PRELIMINARY — SUBJECT TO COMPLETION — DATED JULY 14, 2009
 
MERGER PROPOSED — YOUR VOTE IS VERY IMPORTANT
 
Dear Stockholder:
 
On February 12, 2009, the board of directors of HeartWare International, Inc., or HeartWare, and the board of directors of Thoratec Corporation, or Thoratec, approved a merger of HeartWare and a wholly-owned subsidiary of Thoratec. Before the merger can be completed, the stockholders of HeartWare must vote to adopt the Agreement and Plan of Merger, which we refer to as the merger agreement, dated as of February 12, 2009, by and among HeartWare, Thoratec, Thomas Merger Sub I, Inc., a direct wholly owned subsidiary of Thoratec, which we refer to as Merger Subsidiary, and Thomas Merger Sub II, Inc., another direct wholly owned subsidiary of Thoratec, which we refer to as Merger Subsidiary Two.
 
Pursuant to the merger agreement, Merger Subsidiary will merge with and into HeartWare, with HeartWare surviving the merger as a wholly owned subsidiary of Thoratec, which we refer to as the merger. Provided that certain tax-related conditions are satisfied, HeartWare, as the surviving corporation in the merger, will merge with and into Merger Subsidiary Two with Merger Subsidiary Two surviving the merger as a subsidiary of Thoratec, which we refer to as the second merger. The merger and second merger are referred to collectively in this proxy statement/prospectus as the mergers.
 
As a result of the merger, each share of HeartWare common stock will be converted into the right to receive $14.30 in cash and 0.6054 of a share of Thoratec common stock. Holders of HeartWare CHESS Depositary Interests, which we refer to as HeartWare CDIs and are traded on the Australian Securities Exchange and which represent 1/35 of a share of HeartWare common stock, will be entitled to receive in exchange for each of their HeartWare CDIs a combination of approximately $0.4085 in cash and approximately 0.01729 of a share of Thoratec common stock. In addition, if the volume weighted average of the per share closing prices of Thoratec common stock on The NASDAQ Stock Market for the twenty (20) consecutive trading days ending on and including the fifth (5th) trading day prior to, but not including, the closing date is less than or equal to $18.38, then HeartWare will have an option to terminate the merger agreement unless, subject to certain adjustments provided for in the merger agreement, Thoratec increases the number of shares of Thoratec common stock payable in the merger such that the value of the stock portion of the merger consideration at closing is equal to 70% of the value of the aggregate Thoratec stock consideration payable in the merger (calculated using the $26.25 price per share of Thoratec common stock used to determine the stock portion of the merger consideration). If that same volume weighted average price is equal to or exceeds $34.13 (130% of the $26.25 price per share of Thoratec common stock used to determine the stock portion of the merger consideration), then Thoratec may reduce the number of shares of Thoratec common stock payable in the merger such that the value of the stock portion of the merger consideration at closing is equal to 130% of the value of the aggregate Thoratec stock consideration payable in the merger (calculated using the $26.25 price per share of Thoratec common stock used to determine the stock portion of the merger consideration). Each HeartWare CDI is exchangeable at the option of the holder of the HeartWare CDI into shares of HeartWare common stock at the ratio of one (1) share of common stock for every thirty-five (35) HeartWare CDIs held by such holder and as a result of the merger, holders of HeartWare CDIs will be entitled to receive 1/35 of the merger consideration described above for each HeartWare CDI held by such holder.
 
If certain tax-related conditions are satisfied, the transaction will be structured to qualify as a “reorganization” for U.S. federal income tax purposes, pursuant to which the amount of gain, if any, recognized by a U.S. holder of HeartWare common stock in the merger shall not exceed the cash portion of the merger consideration received. If the transaction is not structured to qualify as a “reorganization,” the transaction will be fully taxable to HeartWare stockholders for U.S. federal income tax purposes. As a result, in deciding whether to vote to adopt the merger agreement, you should consider the possibility that the transaction will be structured as a fully taxable transaction for U.S. federal income tax purposes because the stock value condition (as defined herein) is not satisfied. You will not be entitled to change your vote or vote again in the event that the stock value condition is not satisfied and the transaction is structured as a fully taxable transaction for U.S. federal income tax purposes. Other than the


Table of Contents

U.S. federal income tax consequences described above, neither HeartWare nor Thoratec is aware of any material effects on HeartWare stockholders if the second merger does not occur. HeartWare has sought a ruling from Australian tax authorities to confirm that a holder of shares of HeartWare common stock that is a resident of Australia for Australian tax purposes may choose to apply scrip-for-scrip roll-over relief to disregard any capital gain that results to it from the cancellation of its HeartWare common stock to the extent that the capital gain is attributable to the stock portion of the merger consideration it receives under the merger contemplated by the merger agreement.
 
The market prices of Thoratec common stock, HeartWare common stock and HeartWare CDIs will fluctuate before the merger. You should obtain current stock price quotations for Thoratec common stock, HeartWare common stock and HeartWare CDIs. HeartWare common stock is quoted on The NASDAQ Global Market under the symbol “HTWR” and HeartWare CDIs are quoted on the Australian Securities Exchange or ASX under the symbol “HIN”. Thoratec common stock is quoted on The NASDAQ Global Select Market under the symbol “THOR”.
 
At a special meeting of HeartWare stockholders, HeartWare stockholders will be asked to vote on the adoption of the merger agreement and certain other matters. The adoption of the merger agreement requires the affirmative vote of the holders of a majority of the outstanding shares of HeartWare common stock entitled to vote. Holders of HeartWare CDIs have a right to direct CHESS Depositary Nominees Pty Limited, the stockholder of record and which we refer to as CDN, on how it should vote its shares and are being requested to give directions to CDN to vote in accordance with the instructions set forth in this proxy statement/prospectus.
 
The HeartWare board of directors recommends that HeartWare stockholders vote “FOR” the proposal to adopt the merger agreement and “FOR” the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies.
 
This document describes the special meeting, the merger, the documents related to the merger and other related matters. Please carefully read this entire document, including all of its annexes. In particular, we encourage you to read the section entitled “Risk Factors” beginning on page 25 for a discussion of the risks relating to the proposed merger. You can also obtain information about Thoratec and HeartWare from documents that each of us has filed with the U.S. Securities and Exchange Commission, or the SEC.

QUESTIONS AND ANSWERS ABOUT THE MERGER
 
The following are some questions that you, as a stockholder of HeartWare or a holder of HeartWare CDIs, may have regarding the merger and the special meeting of stockholders of HeartWare and brief answers to those questions. We urge you to carefully read the remainder of this proxy statement/prospectus because the information in this section does not provide all the information that might be important to you with respect to the adoption of the merger agreement and the other matters being considered at the HeartWare special meeting of stockholders or the issuance of Thoratec common stock in connection with the merger. Additional important information is also contained in the annexes to, and the documents incorporated by reference in, this proxy statement/prospectus.
 
Q: Why am I receiving this proxy statement/prospectus?
 
A: Thoratec has agreed to acquire HeartWare under the terms of the merger agreement. Please see the section entitled “The Merger Agreement” beginning on page 83 of this proxy statement/prospectus for a more detailed summary of the terms and conditions contained in the merger agreement. A copy of the merger agreement is attached to this proxy statement/prospectus as Annex A.
 
In order to complete the merger, HeartWare stockholders must adopt the merger agreement and all other conditions to the consummation of the merger must be satisfied or waived. HeartWare will hold a special meeting of its stockholders, which we refer to as the HeartWare special meeting, to obtain the required approval of HeartWare stockholders to adopt the merger agreement.
 
Q: What are HeartWare stockholders being asked to vote on?
 
A: HeartWare stockholders are being asked to consider and vote on the adoption of the merger agreement and the adjournment of the special meeting to a later date, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the meeting to adopt the merger agreement.
 
Q: What vote is required to adopt the merger agreement?
 
A: The adoption of the merger agreement requires the affirmative vote of a majority of the outstanding shares of HeartWare common stock, including shares of HeartWare common stock represented by HeartWare CDIs, entitled to vote at the HeartWare special meeting. In connection with the transactions contemplated by the merger agreement, all but one of the directors on HeartWare’s board of directors and certain executive officers of HeartWare, who collectively beneficially own in the form of HeartWare CDIs (and in the case of Mr. Douglas Godshall, in the form of shares of HeartWare common stock), as of the HeartWare record date, approximately 1.6% of the total outstanding shares of HeartWare common stock, and Apple Tree Partners I, L.P., who beneficially owns in the form of HeartWare CDIs, as of the HeartWare record date, approximately 30.0% of the total outstanding shares of HeartWare common stock have entered into separate support agreements dated as of February 12, 2009, to, among other things, vote or give directions to vote their respective shares of HeartWare common stock, “FOR” the adoption of the merger agreement with Thoratec, subject to the terms and conditions of the support agreements. Please see the section entitled “The Support Agreements” beginning on page 109 of this proxy statement/prospectus for a more detailed summary of the terms and conditions contained in the support agreements. Copies of the form of support agreements are attached to this proxy statement/prospectus as Annex D and Annex E.
 
Q: What vote is required to adopt the proposal to adjourn the special meeting to a later time, if necessary or appropriate, to solicit additional proxies?
 
A: Assuming a quorum is present at the HeartWare special meeting, the adoption of the proposal to adjourn the special meeting to a later time, if necessary or appropriate, to solicit additional proxies requires the affirmative vote of a majority of shares of HeartWare common stock represented in person or by proxy at the special meeting and entitled to vote thereon.
 
Q: What will happen in the proposed mergers?
 
A: Pursuant to the terms of the merger agreement, Merger Subsidiary will merge with and into HeartWare, with HeartWare surviving the merger as a wholly owned subsidiary of Thoratec. Provided that certain tax-related conditions are met as more fully described in the section entitled “The Merger Agreement — Conditions to the Obligations of Each Party to Consummate the Second Merger” beginning on page 99 of this proxy statement/prospectus, then immediately after the merger, HeartWare, as the surviving corporation in the merger, will


1


Table of Contents

merge with and into Merger Subsidiary Two with Merger Subsidiary Two surviving the second merger as a wholly owned subsidiary of Thoratec.
 
Q: What will HeartWare stockholders receive in the merger?
 
A: As a result of the merger, shares owned by holders of HeartWare common stock, including shares of HeartWare common stock represented by HeartWare CDIs, will be converted into the right to receive in exchange for each full share of HeartWare common stock, $14.30 in cash and 0.6054 of a share of Thoratec common stock.
 
In addition, if the volume weighted average of the per share closing prices of Thoratec common stock on The NASDAQ Stock Market for the twenty (20) consecutive trading days ending on and including the fifth (5th) trading day prior to, but not including, the closing date is equal to or less than $18.38, then HeartWare will have an option to terminate the merger agreement unless, subject to certain adjustments provided for in the merger agreement, Thoratec increases the number of shares of Thoratec common stock payable in the merger such that the value of the stock portion of the merger consideration at closing is equal to 70% of the value of the aggregate Thoratec stock consideration payable in the merger (calculated using the $26.25 price per share of Thoratec common stock used to determine the stock portion of the merger consideration). If that same volume weighted average price is equal to or exceeds $34.13 (130% of the $26.25 price per share of Thoratec common stock used to determine the stock portion of the merger consideration), then Thoratec may reduce the number of shares of Thoratec common stock payable in the merger such that the value of the stock portion of the merger consideration at closing is equal to 130% of the value of the aggregate Thoratec stock consideration payable in the merger (calculated using the $26.25 price per share of Thoratec common stock used to determine the stock portion of the merger consideration).
 
Each HeartWare CDI is exchangeable at the option of the HeartWare CDI holder into shares of HeartWare common stock at the ratio of one (1) share of HeartWare common stock for every thirty-five (35) HeartWare CDIs, and, as a result of the merger, holders of HeartWare CDIs will be entitled to receive 1/35 of the merger consideration described above for each HeartWare CDI held by such holder.
 
Q: What will happen if the value of the stock portion of the merger consideration payable at the effective time of the merger is equal to or less than 70% of the value of the aggregate Thoratec stock consideration as of February 12, 2009 (the date of execution of the merger agreement)?
 
A: Depending on the facts and circumstances then existing, the HeartWare board of directors may or may not determine to exercise HeartWare’s right to terminate the merger agreement as described above. If the HeartWare board of directors determines not to exercise HeartWare’s right to terminate the merger agreement, the HeartWare stockholders may receive Thoratec common stock as consideration in the merger with a per share value of less than $18.38, or 70% of the value of the stock consideration used to determine the merger consideration at signing. If the HeartWare board of directors determines, based on the facts and circumstances existing at the time, not to exercise its right to terminate the merger agreement, HeartWare does not intend to resolicit the votes of its stockholders regarding their adoption of the merger agreement. After the HeartWare board of directors determines, based on the facts and circumstances existing at that time, whether to exercise its right to terminate the merger agreement, HeartWare will promptly notify its stockholders of such determination by issuing a press release announcing such determination, including the basis for the HeartWare board of directors’ determination, as well as filing such press release with the SEC on Form 8-K.
 
Accordingly, in determining whether to vote to adopt the merger agreement, HeartWare stockholders should be mindful that the per share value of the Thoratec common stock they receive in the merger could, as of the effective time of the merger, be less than $18.38, with the result that the value of the aggregate merger consideration payable for each share of HeartWare common stock, as of the effective time of the merger, could be less than $25.43 per share, i.e. $18.38 multiplied by the 0.6054 shares of Thoratec common stock payable in the merger plus $14.30 in cash, (as compared to a value of $30.19 per share of HeartWare common stock as of February 12, 2009, the date of execution of the merger agreement).
 
Q: What will holders of HeartWare CDIs receive in the merger?
 
A: Each HeartWare CDI is exchangeable at the option of the holder of the HeartWare CDI into shares of HeartWare common stock at the ratio of one (1) share of common stock for every thirty-five (35) HeartWare CDIs held by such holder and, as a result of the merger, holders of HeartWare CDIs will be entitled to receive 1/35 of the merger consideration described above for each HeartWare CDI held by such holder. Holders of HeartWare CDIs who do not convert their CDIs into shares of HeartWare common stock prior to the closing date of the merger will

Table of Contents

receive their merger consideration through Computershare Investor Services Pty Ltd, which we refer to as Computershare on behalf of CDN.
 
Q: Does the HeartWare board of directors support the merger?
 
A: Yes. The HeartWare board of directors, by unanimous vote of those present at a meeting duly called, has approved and declared the advisability of the merger agreement and has determined that the merger and the other transactions contemplated by the merger agreement are fair to and in the best interests of HeartWare and its stockholders and recommends that you vote “FOR” the proposal to adopt the merger agreement. You should read the section entitled, “HeartWare’s Reasons for the Merger and Recommendation of the HeartWare Board of Directors” beginning on page 55. The HeartWare board of directors also recommends that you vote “FOR” the adoption of the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies to facilitate the adoption of the merger agreement.
 
Q: Are there risks involved in undertaking the merger?
 
A: Yes. In evaluating the merger, HeartWare stockholders should carefully consider the factors discussed in the section of this proxy statement/prospectus entitled “Risk Factors” beginning on page 25 and other information about HeartWare and Thoratec included in the documents incorporated by reference in this proxy statement/prospectus.
 
Q: Where and when is the HeartWare special meeting?
 
A: The HeartWare special meeting will be held on • , 2009, at • , U.S. Eastern time ( • , Australia Eastern Standard Time on • , 2009), at • .

A: HeartWare stockholders can vote their shares in connection with the HeartWare special meeting if they owned HeartWare shares of common stock at the close of business, U.S. Eastern time, on June 25, 2009 (7:00 a.m., Australia Eastern Standard Time on June 26, 2009), the record date for the HeartWare special meeting. As of the close of business on that day, 8,924,351 shares of HeartWare common stock were outstanding, including shares represented by HeartWare CDIs.
 
Q: What do holders of shares of HeartWare common stock need to do now?
 
A: If you are a HeartWare stockholder, after you have carefully read this proxy statement/prospectus, including the annexes and the other documents referred to in this proxy statement/prospectus and have decided how you wish to vote your shares, please submit a proxy to vote your shares promptly as described below. You have one (1) vote for each share of HeartWare common stock you own as of the record date and a proportionate vote for any fractional shares so held.
 
Q: How do I vote if I am a holder of record of HeartWare common stock?
 
A: If you are a holder of record of HeartWare common stock, after you have carefully read this document and have decided how you wish to vote your shares of common stock, please vote as soon as possible by:
 
• completing, signing and dating each HeartWare proxy card you receive and returning it in the enclosed postage-prepaid envelope by mail; or
 
• voting in person by appearing at the special meeting.
 
Mailing in your proxy card will not prevent you from attending the special meeting. You are encouraged to submit a proxy by mail even if you plan to attend the special meeting in person to ensure that your shares of HeartWare common stock are represented at the special meeting.
 
If you return your signed proxy card, but do not mark the boxes showing how you wish to vote, your shares will be voted “FOR” the proposal to adopt the merger agreement and “FOR” the adoption of the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies.
 
If you would like to attend the HeartWare special meeting, see “Can I attend the HeartWare special meeting and vote my shares in person?” below.

Q: How do I vote if my shares are held by a brokerage firm, bank, trust or other nominee?
 
A: If you are a stockholder who holds shares of HeartWare common stock through a brokerage account or other nominee, such as a bank or trust, after you have carefully read this document and have decided how you wish to vote your shares, please submit a proxy for your shares promptly. If you hold your shares of HeartWare common stock through a brokerage account or another nominee, such as a bank or trust, then the brokerage firm, bank, trust or other nominee is considered to be the stockholder of record with respect to those shares of common stock. However, you are still considered to be the beneficial owner of those shares, with your shares being held in “street name”. “Street name” holders generally cannot vote their shares directly and must instead direct their brokerage firm, bank, trust or other nominee on how to vote their shares. Your brokerage firm, bank, trust or other nominee will only be permitted to vote your shares for you at the special meeting for the proposal to adopt the merger agreement if you instruct it on how to vote in accordance with the instruction form included with these materials and forwarded to you by your brokerage firm, bank, trust or other nominee. Submitting your proxy card or directing your brokerage firm, bank, trust or other nominee to vote your shares will ensure that your shares are represented and voted at the HeartWare special meeting. Without instructions, your shares will not be voted on the proposal to adopt the merger agreement, which will have the effect described below under the question, “What if I abstain from voting or fail to instruct my brokerage firm, bank, trust or other nominee on how to vote?”
 
In addition, because any shares you may hold in “street name” will be deemed to be held by a different stockholder than any shares you hold of record, shares held in “street name” will not be combined for voting purposes with shares you hold of record. To be sure your shares are voted, you should instruct your brokerage firm, bank, trust or other nominee to vote your shares. Shares held by a corporation or business entity must be voted by an authorized officer of the entity.
 
Q: How do I vote if my shares are held in the form of HeartWare CDIs?
 
A: If you are a holder of HeartWare CDIs, you may attend the special meeting but cannot vote your HeartWare CDIs in person at the special meeting. In order to vote your shares in person, you must have converted your HeartWare CDIs into HeartWare common stock before the record date for the HeartWare special meeting. If you wish to convert your HeartWare CDIs, you should contact Computershare as soon as possible to find out how to convert your HeartWare CDIs into shares of HeartWare common stock and how long the conversion process will take.
 
If you are a holder of HeartWare CDIs and you do not wish to convert your HeartWare CDIs into shares of HeartWare common stock, you have a right to direct CDN, the stockholder of record, on how it should vote the shares of HeartWare common stock underlying your HeartWare CDIs in relation to each proposal. After you have carefully read this document and have decided how you wish to direct CDN to cast proxy votes with respect to the shares of HeartWare common stock underlying your HeartWare CDIs, please submit your voting instructions as soon as possible by submitting instructions to CDN to vote the underlying shares on your behalf at the meeting on each proposal according to your directions by:
 
• returning by mail the enclosed CDI Voting Instruction Form (instructions on how to fill out the form are set out on the back of the form or on Computershare’s website at www.computershare.com.au) to Computershare, using the enclosed postage-prepaid envelope or by mailing it to Computershare Investor Services Pty Ltd, GPO Box 242 Melbourne Victoria 3001 Australia or by faxing it to Computershare to (within Australia) 1800 783 447 or (outside Australia) +61 3 9473 2555; or
 
• submitting your voting instructions via Computershare’s website at www.computershare.com.au. You will need your Holder Identification Number or Security Holder Reference Number, which is shown on the enclosed CDI Voting Instruction Form. You will be taken to have signed the CDI Voting Instruction Form if you submit your instructions in accordance with the directions on the website.
 
If you are a holder of HeartWare CDIs, CDN cannot vote your HeartWare CDIs without instructions from you. You should instruct CDN how to vote your shares by following the directions on the CDI Voting Instruction Form. Without instructions, your HeartWare CDIs will not be voted, which will have the effect described below under the question “What if I abstain from voting or fail to instruct CDN on how to vote my HeartWare CDIs?” below.

Q: What is the last day for holders of HeartWare CDIs to submit voting instructions to Computershare?
 
A: If you are a holder of HeartWare CDIs directing CDN to vote the underlying shares of HeartWare common stock on your behalf, the latest time for receipt of CDI Voting Instruction Forms (and any necessary supporting documents) via mail and voting instructions via Internet is • , U.S. Eastern time on • , 2009 ( • , Australia Eastern Standard Time on • , 2009).
 
Q: Why is my vote as a HeartWare stockholder important?
 
A: If you do not vote by proxy or vote in person at the HeartWare special meeting, it will be more difficult for HeartWare to obtain the necessary quorum to hold its special meeting. In addition, your failure to vote, whether by proxy or in person, will have the same effect as a vote “AGAINST” adoption of the merger agreement. The merger agreement must be adopted by the affirmative vote of the holders of a majority of the outstanding shares of HeartWare common stock (including shares represented by HeartWare CDIs) entitled to vote at the special meeting. The HeartWare board of directors recommends that you vote “FOR” the proposal to adopt the merger agreement.
 
Q: What constitutes a quorum for the special meeting?
 
A: The presence, in person or by proxy, of stockholders representing a majority of the shares of HeartWare common stock entitled to vote at the special meeting, including shares represented by HeartWare CDIs, will constitute a quorum for the special meeting. If you are a stockholder of record and you submit a properly executed proxy card or vote in person at the special meeting, then your shares will be counted as part of the quorum. Abstentions and broker non-votes will be treated as present at the HeartWare special meeting for purposes of determining the presence or absence of a quorum. All shares of HeartWare common stock held by stockholders (including shares represented by HeartWare CDIs) that are present in person or represented by proxy and entitled to vote at the special meeting, regardless of how such shares are voted or whether such stockholders abstain from voting, will be counted in determining the presence of a quorum.
 
If CDN has received directions to vote shares of HeartWare common stock underlying HeartWare CDIs in accordance with the procedures set out in this proxy statement/prospectus and on the CDI Voting Instruction Form, regardless of whether the directions are to vote the shares “FOR”, “AGAINST” or to abstain from voting, those shares of HeartWare common stock will be counted in determining the presence of a quorum. If you fail to instruct CDN to vote the shares of HeartWare common stock underlying your HeartWare CDIs, the shares of HeartWare common stock underlying your HeartWare CDIs will not be treated as present at the HeartWare special meeting for purposes of determining the presence or absence of a quorum.
 
Q: What if I abstain from voting or fail to instruct my brokerage firm, bank, trust or other nominee on how to vote my shares of HeartWare common stock?
 
A: If you fail to instruct your brokerage firm, bank, trust or other nominee to vote your shares, the nominee will not be able to vote your shares on the proposal to adopt the merger agreement. Because the adoption of the merger agreement requires an affirmative vote of a majority of the outstanding shares of HeartWare common stock for approval, your abstention from voting or your failure to provide your nominee with voting instructions will have the same effect as a vote “AGAINST” the proposal to adopt the merger agreement. Because your brokerage firm, bank, trust or other nominee does have discretionary authority to vote on the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies, your broker or other nominee may vote your shares in its discretion on this proposal. If your broker or other nominee affirmatively abstains from voting your shares in its discretion on this proposal, it will have the same effect as a vote “AGAINST” the proposal to adjourn the special meeting.
 
Q: What if I abstain from voting or fail to instruct CDN on how to vote my HeartWare CDIs?
 
A: If you are a holder of HeartWare CDIs, CDN cannot vote the shares of HeartWare common stock underlying your HeartWare CDIs on your behalf without instructions from you. You should instruct CDN as to how to vote the underlying shares, following the directions CDN provides to you. Please check the CDI Voting Instruction Form used by CDN. Without instructions, CDN cannot vote on your behalf. If you instruct CDN to abstain from voting the shares of HeartWare common stock underlying your HeartWare CDIs, or you fail to instruct CDN to vote the underlying shares of HeartWare common stock with respect to the proposal to adopt the merger agreement, your direction to abstain from voting on the proposal or failure to instruct CDN will have the same effect as a vote

Table of Contents

“AGAINST” the proposal to adopt the merger agreement. In addition, if you instruct CDN to abstain from voting on the proposal to adjourn the HeartWare special meeting, if necessary or appropriate, in order to solicit additional proxies, or you fail to instruct CDN to vote on this proposal, your instruction to CDN to abstain from voting or your failure to instruct CDN will have the same effect as a vote “AGAINST” the proposal to adjourn the HeartWare special meeting, if necessary or appropriate, in order to solicit additional proxies.
 
Q: How are votes counted?
 
A: Votes will be counted by the inspector of election appointed for the special meeting, who will separately count “FOR” and “AGAINST” votes and abstentions. Because the adoption of the merger agreement requires the affirmative vote of a majority of the outstanding shares of HeartWare common stock, your failure to vote, your failure to provide voting instructions to your broker or nominee or your abstention from voting will have the same effect as a vote against the adoption of the merger agreement. Because the adoption of the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies, requires the affirmative vote of a majority of the shares of HeartWare common stock represented in person or by proxy at the special meeting, abstentions will count as a vote against the proposal and the failure to vote your shares will not affect the outcome of the proposal.
 
CDN, on behalf of the holders of HeartWare CDIs, will vote the underlying shares of HeartWare common stock represented by the HeartWare CDIs on an aggregate basis by (i) determining the total number of HeartWare CDIs “FOR” each proposal, (ii) determining the total number of HeartWare CDIs “AGAINST” each proposal, (iii) determining the total number of HeartWare CDIs abstaining from voting on each proposal, (iv) applying the ratio of one (1) share of HeartWare common stock for every thirty-five (35) HeartWare CDIs and (v) submitting the resultant number of shares of HeartWare common stock “FOR” each proposal and “AGAINST” each proposal and the number of shares abstaining from voting on each proposal, as appropriate.
 
Q: Can I attend the HeartWare special meeting and vote my shares in person?
 
A: All holders of HeartWare common stock, including stockholders of record and stockholders who hold their shares through brokerage firms, banks, trusts or other nominees or any other holder of record, and holders of HeartWare CDIs are invited to attend the HeartWare special meeting. If you are not a stockholder of record, you must obtain a proxy, executed in your favor, from the record holder of your shares, such as a brokerage firm, bank, trust or other nominee, to be able to vote in person at the HeartWare special meeting. If you plan to attend the HeartWare special meeting, you must hold your shares in your own name or have a letter from the record holder of your shares confirming your ownership and you must bring a form of personal photo identification with you in order to be admitted. HeartWare reserves the right to refuse admittance to anyone without proper proof of share ownership or without proper photo identification.
 
Holders of HeartWare CDIs are entitled to attend the HeartWare special meeting but cannot vote their HeartWare CDIs in person at the HeartWare special meeting. In order to vote their shares in person, holders of HeartWare CDIs must have converted their HeartWare CDIs into HeartWare common stock before the record date for the HeartWare special meeting. If you wish to convert your HeartWare CDIs into HeartWare common stock you should contact Computershare as soon as possible to find out how to convert your HeartWare CDIs into shares of HeartWare common stock and how long the conversion process will take and follow the instructions under the question, “How do I vote if my shares are held in the form of HeartWare CDIs?” above.
 
Q: Will HeartWare be required to submit the merger agreement to its stockholders even if the HeartWare board of directors has withdrawn, modified or qualified its recommendation?
 
A: Yes. Unless the merger agreement is terminated before the HeartWare special meeting, HeartWare is required to submit the merger agreement to its stockholders even if the HeartWare board of directors has withdrawn, modified or qualified its recommendation, consistent with the terms of the merger agreement.
 
Q: What is the purpose of the second merger, if it occurs?
 
A: As described below, if certain tax-related conditions are satisfied, the transactions contemplated by the merger agreement will be structured to qualify as a “reorganization” for U.S. federal income tax purposes. If the transactions are intended to qualify as a “reorganization” for U.S. federal income tax purposes, the merger of Merger Subsidiary into HeartWare will be followed by a second merger of HeartWare into Merger Subsidiary Two, with Merger Subsidiary Two surviving this second merger as a wholly owned subsidiary of Thoratec. The

Table of Contents

purpose of employing this two-merger structure is to follow the approach of applicable IRS pronouncements to provide protection against the risk of corporate-level tax to Thoratec and HeartWare in the event the mergers do not qualify as a “reorganization”.
 
Q: Will I be subject to U.S. federal income tax on the Thoratec common stock and cash that I receive?
 
A: For HeartWare stockholders that are U.S. persons (as defined in the section entitled, “The Merger — Material U.S. Federal Income Tax Consequences” beginning on page 71), if certain tax-related conditions (described later in this document) are satisfied, the transactions contemplated by the merger agreement will be structured to qualify as a “reorganization” for U.S. federal income tax purposes. If such transactions qualify as a “reorganization,” you will recognize gain, but not loss, equal to the lesser of (i) the amount of cash you received in the merger and (ii) an amount equal to the excess, if any, of (x) the sum of the amount of cash and the fair market value of the Thoratec common stock you received in the merger over (y) the aggregate tax basis in your HeartWare common stock surrendered.
 
If the applicable conditions (described later in this document) are not satisfied, or the Internal Revenue Service, which we refer to as the IRS, successfully challenges the treatment of the mergers as a “reorganization,” the transactions contemplated by the merger agreement will be fully taxable to you for U.S. federal income tax purposes. In this case, you will recognize all of your gain or loss from the exchange of your HeartWare common stock for cash and Thoratec common stock in the merger.
 
Based on the number of shares of HeartWare common stock outstanding as of the HeartWare record date and assuming that no HeartWare stockholder exercises dissenters’ rights, the stock value condition, as described in “The Merger — Material U.S. Federal Income Tax Consequences — Transaction Structure” beginning on page 72 and subject to the discussion therein, will be satisfied if the mean between the high and low selling prices of a share of Thoratec common stock as reported on The NASDAQ Stock Market for the last trading session closing prior to the effective time of the merger, which we refer to as the effective stock price, is at least $16.74, in which case the second merger will occur and (i) Thoratec and HeartWare will treat the merger and the second merger, taken together, as a single integrated transaction for U.S. federal income tax purposes that qualifies as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code, and (ii) as a condition to the completion of the acquisition of HeartWare pursuant to the merger agreement (which condition is not waivable after the receipt of stockholder approval for the merger unless further stockholder approval is obtained with appropriate disclosure), Shearman & Sterling LLP, which we refer to as Shearman, will deliver a tax opinion to HeartWare, and Latham & Watkins LLP, which we refer to as Latham, will deliver a tax opinion to Thoratec, in each case, to the effect that the merger and the second merger, taken together, will constitute a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code. The tax opinions, if delivered, will be based on certain assumptions and on representation letters provided by HeartWare and Thoratec. Thus, if the stock value condition is satisfied but the tax opinions are not delivered, the merger will not occur unless further HeartWare stockholder approval is obtained with appropriate disclosure.
 
Whether the stock value condition is satisfied will depend on the effective stock price, as described above. Other relevant factors will include (i) whether there has been any adjustment to the merger consideration as a result of either (x) HeartWare electing to terminate the merger agreement and Thoratec electing to increase the number of shares of Thoratec common stock payable in the merger or (y) Thoratec electing to reduce the number of shares of Thoratec common stock payable in the merger, as described in “The Merger Agreement — Merger Consideration” beginning on page 83 and (ii) the number of outstanding shares of HeartWare common stock with respect to which HeartWare stockholders exercise dissenters’ rights. See “The Merger — Material U.S. Federal Income Tax Consequences” beginning on page 71.
 
No assurance, however, can be given that the stock value condition will be met because its satisfaction is dependent, in part, on factors that HeartWare and Thoratec do not control. As a result, in deciding whether to vote to adopt the merger agreement, you should consider the possibility that the transaction will be structured as a fully taxable transaction for U.S. federal income tax purposes because the stock value condition is not satisfied. You will not be entitled to change your vote or to vote again in the event that the stock value condition is not satisfied and the transaction is structured as a fully taxable transaction for U.S. federal income tax purposes. Other than the U.S. federal income tax consequences described above, neither HeartWare nor Thoratec is aware of any material effects on HeartWare stockholders if the second merger does not occur.

Assuming an effective stock price of $26.46 of Thoratec common stock, which was the per share closing price on July 2, 2009, and subject to the discussion under “The Merger — Material U.S. Federal Income Tax Consequences” beginning on page 71, the transactions contemplated by the merger agreement would be structured to qualify as a “reorganization” for U.S. federal income tax purposes.
 
We will notify you via a press release announcing the consummation of the merger as to whether or not the acquisition of HeartWare by Thoratec has been structured to qualify as a “reorganization”.
 
You are urged to carefully read the discussion under “The Merger — Material U.S. Federal Income Tax Consequences” beginning on page 71, and to consult your tax advisor on the consequences of participation in the transactions contemplated by the merger agreement.
 
Q: If I am a HeartWare stockholder, can I change or revoke my vote?
 
A: Yes. Regardless of the method you used to cast your vote, if you are a holder of record of shares, you may change your vote by signing and returning a new proxy card with a later date by 11:59 p.m., U.S. Eastern time on • , 2009 ( • , Australia Eastern Standard Time on • , 2009) or by attending the HeartWare special meeting and voting by ballot at the special meeting.
 
If you are a HeartWare stockholder of record of shares and wish to revoke rather than change your vote, you must send a written, signed revocation to HeartWare International, Inc., 205 Newbury Street, Framingham, Massachusetts 01701, which must be received by 11:59 p.m., U.S. Eastern time on • , 2009 ( • , Australia Eastern Standard Time on • , 2009). You must include your control number.
 
If you hold your shares in “street name” and wish to change or revoke your vote, please refer to the information on the voting instruction form included with these materials and forwarded to you by your brokerage firm, bank, trust or other nominee to see your voting options.
 
Any holder of HeartWare common stock entitled to vote in person at the HeartWare special meeting may vote in person regardless of whether a proxy has been previously given, but the mere presence of a stockholder at the special meeting will not constitute revocation of a previously given proxy.
 
Q: If I am a HeartWare CDI holder, can I change or revoke my direction to vote?
 
A: If you are a holder of HeartWare CDIs and have completed and returned your CDI Voting Instruction Form, you may change or revoke the directions contained therein by a written notice of change or revocation to Computershare by no later than • , U.S. Eastern time on • , 2009 ( • , Australia Eastern Standard Time on • , 2009).
 
Q: If I am a HeartWare stockholder with shares represented by stock certificates, should I send in my HeartWare stock certificates now?
 
A: No. You should not send in your HeartWare stock certificates at this time. After the merger, Thoratec will send you instructions for exchanging your shares of HeartWare common stock for the merger consideration. If your shares are held in “street name” by your brokerage firm, bank, trust or other nominee, you will receive instructions from your brokerage firm, bank, trust or other nominee as to how to affect the surrender of your “street name” shares in exchange for the merger consideration. Please do not send in your stock certificates with your proxy card. Similarly, if you are a holder of HeartWare CDIs, you should not send your holding statement(s) with your CDI Voting Instruction Form. After the merger, Thoratec will send CDN instructions for exchanging its shares of HeartWare common stock for the merger consideration and Computershare will arrange for the merger consideration to be sent to HeartWare CDI holders on behalf of CDN.
 
Q: When do you expect to complete the merger?
 
A: HeartWare and Thoratec are working to complete the merger as promptly as practicable. If HeartWare stockholders adopt the merger agreement and we receive the required regulatory approvals described below in “The Merger — Regulatory Matters” beginning on page 78, HeartWare currently expects that the merger will be completed during the second half of 2009. However, it is possible that factors outside our control, including the review of the merger by the Federal Trade Commission, which we refer to as the FTC, or under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, which we refer to as the HSR Act, could require us to complete the merger at a later time or may result in us not completing the merger at all.

For a description of certain matters that could delay or prevent the completion of the merger, please refer to “Risk Factors,” beginning on page 25.
 
Q: Will the shares of Thoratec common stock to be issued as part of the merger consideration be listed on The NASDAQ Stock Market and ASX?
 
A: Pursuant to the terms of the merger agreement, Thoratec will use its reasonable best efforts to cause the shares of Thoratec common stock to be issued in connection with the merger to be approved for listing on The NASDAQ Stock Market upon the occurrence of the effective time of the merger, subject to official notice of issuance.
 
The shares of Thoratec common stock will not be listed on ASX.
 
Q: What happens if I sell my shares of HeartWare common stock or HeartWare CDIs before the special meeting?
 
A: The record date for stockholders entitled to vote at the special meeting is earlier than the date of the special meeting and the expected closing date of the merger. If you hold shares of HeartWare common stock or HeartWare CDIs on the record date for the special meeting but you transfer your shares of HeartWare common stock or your HeartWare CDIs after the record date but before the special meeting, you will, unless special arrangements are made, retain your right to vote, or in the case of HeartWare CDIs, your right to give directions to vote, at the special meeting but will transfer the right to receive the merger consideration to the person to whom you transfer your shares or HeartWare CDIs. In addition, if you sell your shares prior to the special meeting or prior to the effective time of the merger, you will not be eligible to exercise your dissenters’ rights in respect of the merger.
 
Q: Can I dissent and require appraisal of my shares?
 
A: Yes. HeartWare stockholders are entitled to dissenters’ rights under Section 262 of the General Corporation Law of the State of Delaware, which we refer to as the Delaware General Corporation Law, provided that they satisfy the special criteria and conditions set forth in Section 262 of the Delaware General Corporation Law. You must have been a holder of HeartWare common stock as of the record date for the HeartWare special meeting in order to have dissenters’ rights in connection with the merger.
 
Holders of HeartWare CDIs are not entitled to exercise dissenters’ rights in connection with the merger. Accordingly, holders of HeartWare CDIs must have converted their HeartWare CDIs into shares of HeartWare common stock prior to the record date for the HeartWare special meeting in order to have dissenters’ rights in connection with the merger.

Pursuant to the terms of the merger agreement, which is governed by Delaware law, Merger Subsidiary will merge with and into HeartWare, with HeartWare surviving the merger as a wholly owned subsidiary of Thoratec. If the value of the stock portion of the merger consideration to be received by HeartWare stockholders is at least 41% of the aggregate merger consideration at closing (in each case, as determined pursuant to the merger agreement), then immediately following the merger, HeartWare, as the surviving corporation in the merger, will merge with and into Merger Subsidiary Two, with Merger Subsidiary Two surviving the second merger as a wholly owned subsidiary of Thoratec. Upon completion of the mergers, HeartWare common stock will no longer be publicly traded.
 
What HeartWare Stockholders Will Receive in the Merger (page 83)
 
At the effective time of the merger, each share of HeartWare common stock, including shares of common stock represented by HeartWare CDIs, will be converted into the right to receive $14.30 in cash, without interest, and 0.6054 of a share of Thoratec common stock, which we refer to as the merger consideration. However, if the volume weighted average of the per share closing prices of Thoratec common stock on The NASDAQ Stock Market for the twenty (20) consecutive trading days ending on and including the fifth (5th) trading day prior to, but not including, the closing date is equal to or less than $18.38, then HeartWare will have an option to terminate the merger agreement unless, subject to certain adjustments provided for in the merger agreement, Thoratec increases the number of shares of Thoratec common stock payable in the merger such that the value of the stock portion of the merger consideration at closing is equal to 70% of the value of the aggregate Thoratec stock consideration payable in the merger (calculated using the $26.25 price per share of Thoratec common stock used to determine the stock portion of the merger consideration). If that same volume weighted average price is equal to or exceeds $34.13, then Thoratec may reduce the number of shares payable in the merger such that the value of the stock portion of the merger consideration at closing is equal to 130% of the value of the aggregate Thoratec stock consideration payable in the merger (calculated using the $26.25 price per share of Thoratec common stock used to determine the stock portion of the merger consideration).
 
Based on the number of shares of HeartWare common stock and shares issuable upon exercise of stock options and other stock-based awards outstanding as of February 12, 2009, and a price of $26.25 per Thoratec common share (the volume weighted average closing price of Thoratec common shares on The NASDAQ Stock Market for the four (4) trading days preceding the execution of the merger agreement), HeartWare stockholders would receive Thoratec common shares having a market value of approximately $141.0 million in the merger and an aggregate of approximately $141.0 million in cash.
 
Each HeartWare CDI is exchangeable at the option of the holder of the HeartWare CDI into shares of HeartWare common stock at the ratio of one (1) share of common stock for every thirty-five (35) HeartWare CDIs held by such holder and, as a result of the merger, holders of HeartWare CDIs will be entitled to receive 1/35 of the merger consideration described above for each HeartWare CDI held by such holder. Holders of HeartWare CDIs who do not convert their CDIs into shares of HeartWare common stock prior to the closing date of the merger will receive their merger consideration through Computershare on behalf of CDN.
 
Thoratec will not issue any fractional shares of Thoratec common stock in the merger. Each HeartWare stockholder who would otherwise have been entitled to receive a fractional share of Thoratec common stock will

instead receive an amount in cash based on such holder’s proportionate interest in the net proceeds from the sale or sales in the open market by the exchange agent on behalf of such holder of the aggregate fractional shares of Thoratec common stock that such holder otherwise would be entitled to receive.
 
Treatment of Options and Other Equity-Based Awards (page 87)
 
The merger agreement provides that, at or immediately prior to the effective time of the merger, the terms of each then outstanding vested option to purchase shares of HeartWare common stock granted or issued under incentive option agreements or similar arrangements with directors, employees or consultants of HeartWare or under the HeartWare International, Inc. Incentive Option Terms: Non-Executive Directors or the HeartWare International, Inc. 2008 Stock Incentive Plan, which we refer to collectively as HeartWare incentive options, and each outstanding option to purchase shares of HeartWare common stock issued under the HeartWare International, Inc. Employee Stock Option Plan, which we refer to as the HeartWare employee stock option plan, whether or not exercisable or vested, that is outstanding immediately prior to the effective time will be cancelled and will be converted into a right to receive a cash payment, without interest, equal to (i) the excess, if any, of $30.19 over the applicable exercise price per share of HeartWare common stock of such cancelled option multiplied by (ii) the number of shares of HeartWare common stock such holder would have purchased had such holder exercised such cancelled option in full immediately prior to the effective time.
 
At the effective time of the merger, each then outstanding unvested HeartWare incentive option shall cease to represent the right to acquire shares of HeartWare common stock and will be converted into, and deemed to constitute, an option to acquire, on the same terms and conditions as were applicable under such unvested HeartWare incentive option, a number of shares of Thoratec common stock equal to the product of (i) the number of shares of HeartWare common stock represented by such unvested HeartWare incentive option and (ii) 1.1499, and such new option to acquire Thoratec common stock will have an exercise price per share equal to (x) the per share exercise price specified in such unvested HeartWare incentive option divided by (y) 1.1499. The 1.1499 exchange ratio for each outstanding unvested HeartWare incentive option is subject to the same volume weighted average price adjustments to the stock portion of the merger consideration described in the section entitled, “What HeartWare Stockholders Will Receive in the Merger” above.
 
The terms of each right of any kind, contingent or accrued, to receive shares of HeartWare common stock or benefits measured by the value of a number of shares of HeartWare common stock, and each other award of any kind consisting of shares of HeartWare common stock, issued under the HeartWare International, Inc. Restricted Stock Unit Plan, the HeartWare International, Inc. 2008 Stock Incentive Plan or the HeartWare employee stock option plan (including restricted stock, restricted stock units, deferred stock units and dividend equivalents), which we refer to collectively as HeartWare stock-based awards, will be adjusted as necessary to provide that at, or immediately prior to, the effective time, each such HeartWare stock-based award, whether or not exercisable or vested, that is outstanding immediately prior to the effective time, will be cancelled and will be converted into the right to receive a cash payment, without interest, equal to $30.19 multiplied by the number of shares of HeartWare common stock the holder of such HeartWare stock-based award would have received had such HeartWare stock-based award been fully earned, vested and exercisable and had been exercised or settled immediately prior to the effective time.

Dissenters’ Rights (page 79)
 
Dissenters’ rights are statutory rights that enable stockholders to dissent from an extraordinary transaction, such as a merger, and to demand that the corporation pay the “fair value” for their shares as determined by a court in a judicial proceeding instead of receiving the consideration offered to stockholders in connection with the extraordinary transaction. HeartWare stockholders will have dissenters’ rights in connection with the merger. If any dissenting HeartWare stockholder demands to be paid the “fair value” of its dissenting shares, such dissenting shares will not be converted into or exchangeable for the right to receive the merger consideration, and the dissenting stockholder will instead be entitled to be paid the “fair value” of such dissenting shares, as determined by the Delaware Court of Chancery, in accordance with Section 262 of the Delaware General Corporation Law, unless and until such dissenting stockholder (a) withdraws (in accordance with the Delaware General Corporation Law) or (b) effectively loses the right to dissent and receive the “fair value” of such dissenting shares under Section 262 of


12


Table of Contents

the Delaware General Corporation Law. If any dissenting stockholder effectively withdraws or otherwise loses its right to dissent, then as of the later of the occurrence of such event or the closing of the merger, the dissenting shares held by such dissenting stockholder will be cancelled and converted into solely the right to receive the merger consideration, without interest.
 
You must have been a holder of HeartWare common stock as of the record date for the HeartWare special meeting in order to have dissenters’ rights in connection with the merger. Holders of HeartWare CDIs are not entitled to exercise dissenters’ rights in connection with the merger and therefore must have converted their HeartWare CDIs into shares of HeartWare common stock prior to the record date for the HeartWare special meeting in order to have dissenters’ rights in connection with the merger.
 
For a more complete description of dissenters’ rights associated with the mergers, see “The Merger — Dissenters’ Rights” beginning on page 79.
 
Material U.S. Federal Income Tax Consequences (page 71)
 
If certain tax-related conditions contained in the merger agreement (described below) are satisfied, the transaction will be structured to qualify as a “reorganization” for U.S. federal income tax purposes. If the mergers, taken together, qualify as a “reorganization,” you will recognize gain, but not loss, equal to the lesser of (i) the amount of cash you receive in the merger and (ii) an amount equal to the excess, if any, of (x) the sum of the amount of cash and the fair market value of the Thoratec common stock you receive in the merger over (y) the aggregate tax basis in your HeartWare common stock surrendered.
 
These conditions to the transaction being structured to qualify as a “reorganization” for U.S. federal income tax purposes include: (i) the aggregate value of the Thoratec common stock (measured immediately prior to the merger based on the effective stock price) received by HeartWare stockholders in the merger being equal to at least 41% of the value of the aggregate merger consideration (as determined pursuant to the merger agreement), and (ii) the delivery of tax opinions by Shearman to HeartWare, and Latham to Thoratec, in each case to the effect that the mergers, taken together, will constitute a “reorganization” for U.S. federal income tax purposes.
 
The trading value of Thoratec common stock will fluctuate and thus we cannot assure you that these conditions will be satisfied. If the condition described in (i) above, or the stock value condition, is not satisfied, or the IRS successfully challenges the treatment of the mergers, taken together, as a “reorganization,” the merger will not qualify as a “reorganization” for U.S. federal income tax purposes and will be treated as a fully taxable transaction. In such an event, you will recognize and be subject to tax on all of your gain with respect to the disposition of your HeartWare common stock in the merger, including to the extent your HeartWare common stock is exchanged for Thoratec common stock. If the stock value condition is satisfied but the tax opinion condition described in (ii) above is not satisfied, the acquisition of HeartWare pursuant to the merger agreement will not be completed unless further HeartWare stockholder approval is obtained with appropriate disclosure.
 
Based on the number of shares of HeartWare common stock outstanding as of the HeartWare record date and assuming that no HeartWare stockholder exercises dissenters’ rights, the stock value condition, as described in “The Merger — Material U.S. Federal Income Tax Consequences — Transaction Structure” beginning on page 72 and subject to the discussion therein, will be satisfied if the effective stock price is at least $16.74, in which case the second merger will occur and (i) Thoratec and HeartWare will treat the merger and the second merger, taken together, as a single integrated transaction for U.S. federal income tax purposes that qualifies as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code, and (ii) as a condition to the completion of the acquisition of HeartWare pursuant to the merger agreement (which condition is not waivable after the receipt of stockholder approval for the merger unless further stockholder approval is obtained with appropriate disclosure), Shearman will deliver a tax opinion to HeartWare, and Latham will deliver a tax opinion to Thoratec, in each case, to the effect that the merger and the second merger, taken together, will constitute a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code. The tax opinions, if delivered, will be based on certain assumptions and on representation letters provided by HeartWare and Thoratec. If the stock value condition is satisfied but the tax opinions are not delivered, the merger will not occur unless further HeartWare stockholder approval is obtained with appropriate disclosure.
 
Whether the stock value condition will be satisfied depends on the effective stock price, as described above. Other relevant factors will include (i) whether there has been any adjustment to the merger consideration as a result


13


Table of Contents

of either (x) HeartWare electing to terminate the merger agreement and Thoratec electing to increase the number of shares of Thoratec common stock payable in the merger or (y) Thoratec electing to reduce the number of shares of Thoratec common stock payable in the merger, as described in “The Merger Agreement — Merger Consideration” beginning on page 83 and (ii) the number of outstanding shares of HeartWare common stock with respect to which HeartWare stockholders exercise dissenters’ rights. See “The Merger — Material U.S. Federal Income Tax Consequences” beginning on page 71.
 
No assurance, however, can be given that the stock value condition described above will be met. As a result, in deciding whether to vote to adopt the merger agreement, you should consider the possibility that the transaction will be structured as a fully taxable transaction for U.S. federal income tax purposes because the stock value condition is not satisfied. You will not be entitled to change your vote or to vote again in the event that the stock value condition is not satisfied and the transaction is structured as a fully taxable transaction for U.S. federal income tax purposes. Other than the U.S. federal income tax consequences described above, neither HeartWare nor Thoratec is aware of any material effects on HeartWare stockholders if the second merger does not occur.
 
Assuming an effective stock price of $26.46 of Thoratec common stock, which was the per share closing price on July 2, 2009, and subject to the discussion under “The Merger — Material U.S. Federal Income Tax Consequences” beginning on page 71, the transactions contemplated by the merger agreement would be structured to qualify as a “reorganization” for U.S. federal income tax purposes.
 
We will notify you via a press release announcing the consummation of the merger as to whether or not the acquisition of HeartWare by Thoratec has been structured to qualify as a “reorganization”.
 
THE U.S. FEDERAL INCOME TAX CONSEQUENCES DESCRIBED ABOVE MAY NOT APPLY TO ALL HEARTWARE STOCKHOLDERS, INCLUDING CERTAIN HEARTWARE STOCKHOLDERS SPECIFICALLY REFERRED TO ON PAGES 71 THROUGH 78. YOUR TAX CONSEQUENCES, INCLUDING ANY STATE, LOCAL AND NON-U.S. TAX CONSEQUENCES, WILL DEPEND ON YOUR OWN SITUATION. YOU SHOULD CONSULT YOUR TAX ADVISOR TO DETERMINE THE PARTICULAR TAX CONSEQUENCES OF PARTICIPATION IN THE TRANSACTIONS CONTEMPLATED BY THE MERGER AGREEMENT.
 
Recommendation of the HeartWare Board of Directors (page 55)
 
The HeartWare board of directors has, by unanimous vote of those present at a meeting duly called, approved and declared the advisability of the merger agreement and has determined that the merger and the other transactions contemplated by the merger agreement are fair to and in the best interests of HeartWare and its stockholders and recommends that you vote “FOR” the proposal to adopt the merger agreement.
 
To review the background of, and HeartWare’s reasons for, the merger, as well as certain risks related to the merger, see pages 49 through 55, pages 55 through 58 and pages 25 through 31, respectively.
 
Opinion of HeartWare’s Financial Advisor
 
At the meeting of the HeartWare board of directors on February 12, 2009, J.P. Morgan rendered its oral opinion, subsequently confirmed in writing, to the HeartWare board of directors that, as of such date, and based upon and subject to the factors, procedures, assumptions, qualifications and limitations set forth in its opinion, the merger consideration to be paid to the holders of shares of HeartWare common stock in the merger was fair, from a financial point of view, to such holders.
 
The full text of the written opinion of J.P. Morgan dated February 12, 2009, which sets forth, among other things, the assumptions made, procedures followed, matters considered, and qualifications and limitations on the review undertaken in connection with its opinion, is included as Annex F to this proxy statement/prospectus and is incorporated herein by reference. J.P. Morgan provided its opinion for the information of the HeartWare board of directors in connection with and for the purposes of the evaluation of the transactions contemplated by the merger agreement. J.P. Morgan’s written opinion addresses only the consideration to be paid to the holders of shares of HeartWare common stock in the merger, and does not address any other matter. J.P. Morgan’s opinion does not constitute a recommendation to any stockholder of HeartWare as to how such stockholder should vote with respect to any matter.

Interests of HeartWare Directors and Executive Officers in the Mergers (page 65)
 
In considering the recommendation of the HeartWare board of directors with respect to the merger, HeartWare stockholders should be aware that certain executive officers and non-employee directors of HeartWare have certain interests in the merger that may be different from, or in addition to, the interests of HeartWare stockholders generally. The HeartWare board of directors was aware of these interests and considered them, among other matters, when approving the merger agreement and recommending that the HeartWare stockholders vote to adopt the merger agreement. These interests include the following:
 
  •  at the effective time of the merger, each then outstanding vested HeartWare incentive option and each outstanding option to purchase shares of HeartWare common stock issued under the HeartWare employee stock option plan, whether vested or unvested, will be cancelled and will convert into a right to receive the cash payment described above under the section entitled, “Treatment of Options and other Equity-Based Awards” and on page 87. Based upon the number of unvested options to purchase shares of HeartWare common stock issued under the HeartWare employee stock option plan outstanding as of the HeartWare record date, such unvested options held by the HeartWare non-employee directors and executive officers relating to 203,445 shares of HeartWare common stock will be cancelled and will be converted into aggregate cash payments of $2.4 million;
 
  •  at the effective time of the merger, each then outstanding unvested HeartWare incentive option will be converted into an option to acquire, on the same terms and conditions, an equivalent number of shares of Thoratec common stock as converted as described above under the section entitled, “Treatment of Options and other Equity-Based Awards” and on page 87. As of the HeartWare record date, there were no outstanding unvested HeartWare incentive options held by the HeartWare non-employee directors and executive officers.
 
  •  each HeartWare stock-based award (other than options granted or issued under (i) incentive option agreements or similar arrangements with directors and executive officers and (ii) the HeartWare employee stock option plan) will be cancelled and will convert into the right to receive the cash payment described above under the section entitled, “Treatment of Options and other Equity-Based Awards” and on page 87. Based upon the number of such restricted stock units as of the HeartWare record date, such units held by the HeartWare executive officers and non-employee directors relating to 82,138 shares will be cancelled and will be converted into aggregate cash payments of $2.5 million;
 
  •  three (3) of HeartWare’s executive officers have each entered into a retention bonus agreement that requires Thoratec to make certain payments to them upon the occurrence of certain events;
 
  •  two (2) of HeartWare’s executive officers have accepted offer letters with Thoratec that will be effective at the effective time of the merger. Additionally, these executive officers have each entered into a separation benefits agreement with Thoratec that becomes effective on the effective time of the merger, which supersedes such executive officer’s employment agreement with HeartWare. This agreement requires Thoratec to make certain payments and provide certain benefits if the executive officer’s employment is involuntarily terminated by Thoratec without “cause” or by the executive for “good reason” as defined in the agreement; and
 
  •  subject to certain conditions, HeartWare will also be permitted to award additional cash retention bonuses to other HeartWare employees, payable on or following the effective time of the merger. The maximum aggregate amount payable (inclusive of any and all payments, reimbursements and tax gross ups) pursuant to such bonuses and the three (3) retention bonus agreements described above will be $8.0 million.

Comparison of Rights of Shareholders of Thoratec and Stockholders of HeartWare (page 112)
 
HeartWare stockholders, whose rights are currently governed by the Certificate of Incorporation of HeartWare, Bylaws of HeartWare and Delaware law, will, upon completion of the merger, become shareholders of Thoratec and their rights will be governed by the Amended and Restated Articles of Incorporation of Thoratec, the Amended and Restated By-laws of Thoratec and California law.

The Merger Agreement
 
Conditions to the Completion of the Mergers (pages 98 through 99)
 
Currently the companies expect to complete the mergers in the second half of 2009. As more fully described in this document and in the merger agreement, the completion of the merger depends on a number of conditions being satisfied or, where legally permissible, waived. These conditions include, among others, receipt of the requisite approval of HeartWare stockholders, the expiration or termination of the required waiting period under the HSR Act and the absence of legal impediments to the consummation of the merger. See “The Merger — Regulatory Matters” for a description of the request for additional information regarding HeartWare and Thoratec from the FTC. As more fully described in this document and in the merger agreement, a copy of which is attached to this proxy statement/prospectus as Annex A, the completion of the second merger depends on the satisfaction of certain tax-related conditions.
 
We cannot be certain when, or if, the conditions to the mergers will be satisfied or waived, or that the mergers will be completed.
 
For a more complete description of the conditions to completion of the mergers, see “The Merger Agreement — Conditions to the Obligations of Each Party to Consummate the Merger,” “— Conditions to the Obligations of Thoratec and Merger Subsidiary to Consummate the Merger,” “— Conditions to the Obligations of HeartWare to Consummate the Merger” and “— Conditions to the Obligations of Each Party to Consummate the Second Merger”.
 
Termination of the Merger Agreement; Termination Fee (pages 100 through 102)
 
The merger agreement contains provisions addressing the circumstances under which HeartWare or Thoratec may terminate the merger agreement. In addition, the merger agreement provides that, in certain circumstances, HeartWare may be required to pay Thoratec a termination fee of $11.3 million or, in certain other circumstances, $5.0 million.
 
For a more complete description, see “The Merger Agreement — Termination” and “— Termination Fee”.
 
Regulatory Matters (page 78)
 
Both HeartWare and Thoratec have agreed to use reasonable best efforts to obtain all regulatory approvals required to complete the transactions contemplated by the merger agreement and both Thoratec and HeartWare have agreed to use their respective reasonable best efforts to take all actions necessary to cause the termination of any waiting period under the HSR Act to be satisfied as soon as practicable. HeartWare and Thoratec have completed the initial filing of applications and notifications to obtain the expiration or termination of the waiting period under the HSR Act. On March 26, 2009, each of HeartWare and Thoratec received a request for additional information, or a second request, from the FTC. Each of HeartWare and Thoratec has substantially complied with the second request and the parties are waiting for a final determination from the FTC. Although the companies do not know of any reason as to why they cannot obtain these regulatory approvals in a timely manner, they cannot be certain when or if they will obtain them.
 
For a more complete description of these regulatory matters, see “The Merger — Regulatory Matters”.
 
The Support Agreements (pages 109 through 110)
 
As a condition to its entering into the merger agreement, Thoratec required certain stockholders of HeartWare to each enter into a support agreement with Thoratec with respect to all of the shares of HeartWare common stock and HeartWare CDIs beneficially owned by such stockholders on the date thereof, along with all such shares purchased or beneficially acquired after the execution of the support agreements and, pursuant to the support agreements, such stockholders have agreed to vote such shares of HeartWare common stock and HeartWare CDIs held by them in favor of the adoption of the merger agreement and, subject to certain exceptions, have agreed not to dispose of their shares prior to the date of the HeartWare special meeting.

The Loan Documents
 
The Loan Agreement (pages 103 through 107)
 
Concurrent with the execution and delivery of the merger agreement, Thoratec entered into a loan agreement with HeartWare and all of HeartWare’s subsidiaries, as guarantors, pursuant to which Thoratec agreed to deposit up to an aggregate of $28.0 million into an escrow account and to loan such funds through one or more term loans to HeartWare, subject to the terms and conditions set forth in the loan agreement, in order to fund the ongoing operations of HeartWare through the anticipated closing of the merger.
 
Thoratec has deposited $20.0 million into the escrow account, although HeartWare could not borrow any funds prior to May 1, 2009. Beginning as of May 1, 2009, HeartWare may borrow up to an aggregate of $12.0 million of funds and, beginning on July 31, 2009, HeartWare may borrow up to an aggregate of $20.0 million of funds. In the event that all of the conditions to closing the merger have been satisfied (other than those conditions that, by their terms, are not capable of being satisfied until the closing, and the condition that relates to the expiration or termination of the applicable waiting period under the HSR Act) and Thoratec exercises an option under the merger agreement to extend the outside date for the completion of the merger until January 31, 2010, HeartWare may borrow up to an additional $8.0 million, which Thoratec must deposit into the escrow account at the time it exercises its extension option. The maximum aggregate amount that HeartWare may borrow under the loan agreement shall not exceed $28.0 million.
 
In the event that the merger agreement is terminated in accordance with its terms, Thoratec may convert the outstanding principal amount of the loans to HeartWare, including any accrued and unpaid interest, as well as any amounts remaining in the escrow account that have not been loaned to HeartWare, in whole or in part, into shares of HeartWare common stock based on a conversion rate equal to (i) $21.5355 per share of HeartWare common stock in the event the mergers are not consummated as a result of a termination of the merger agreement by either HeartWare or Thoratec due to a competing acquisition proposal that the HeartWare board of directors determines is a superior proposal in accordance with the terms of the merger agreement or (ii) $35.00 Australian dollars per share of HeartWare common stock in the event the merger agreement is terminated for any other reason, in each case subject to adjustment as provided in the loan agreement.
 
The outstanding loans to HeartWare under the loan agreement accrue interest at the rate of 10% per annum and are due and payable, together with accrued and unpaid interest, on the earlier of (i) November 1, 2011, (ii) the date on which all of the loans and all of the amounts held in the escrow account have been converted into HeartWare’s common stock in accordance with the loan agreement and (iii) the date on which all of the loans become due and payable in full in accordance with the loan agreement.
 
For a more complete description of the loan agreement, see “The Loan Agreement”.
 
The Investor’s Rights Agreement (pages 108 through 109)
 
Concurrent with the execution of the loan agreement, HeartWare and Thoratec entered into an investor’s rights agreement pursuant to which HeartWare has agreed to provide certain registration rights with respect to any HeartWare common stock issued upon the conversion of the loans or any amounts held in the escrow account, as further described under the heading “The Loan Agreement — Conversion of Loans”.
 
For a more complete description of the investor’s rights agreement, see “The Investor’s Rights Agreement”.
 
The HeartWare Special Meeting
 
Date, Time and Place
 
The special meeting of HeartWare stockholders will be held on • , 2009, at • , U.S. Eastern time ( • , Australia Eastern Standard Time on • , 2009), at • . At the HeartWare special meeting, HeartWare stockholders will be asked to consider and vote upon the adoption of the merger agreement and the adjournment of the HeartWare special meeting, if necessary or appropriate, to permit further solicitation of proxies if there are not sufficient votes at the time of the HeartWare special meeting to adopt the merger agreement.

Table of Contents

 
Record Date; Voting Power; Quorum (page 32)
 
Holders of record of HeartWare common stock are entitled to vote at the HeartWare special meeting if they owned shares of HeartWare common stock as of the close of business, U.S. Eastern time on June 25, 2009 (7:00 a.m., Australia Eastern Standard Time on June 26, 2009), the HeartWare record date.
 
As of the HeartWare record date, there were 8,924,351 shares of HeartWare common stock (including shares represented by HeartWare CDIs) entitled to vote at the HeartWare special meeting. Stockholders will have one vote at the HeartWare special meeting for each share of HeartWare common stock that they owned on the HeartWare record date and a proportionate vote for any fractional shares so held. CDN, on behalf of the holders of HeartWare CDIs, will vote the underlying shares of HeartWare common stock represented by the HeartWare CDIs on an aggregate basis by (i) determining the total number of HeartWare CDIs “FOR” each proposal, (ii) determining the total number of HeartWare CDIs “AGAINST” each proposal, (iii) determining the total number of HeartWare CDIs abstaining from voting on each proposal, (iv) applying the ratio of one (1) share of HeartWare common stock for every thirty-five (35) HeartWare CDIs and (v) submitting the resultant number of shares of HeartWare common stock “FOR” each proposal and “AGAINST” each proposal and the number of shares abstaining from voting on each proposal, as appropriate.
 
As of the HeartWare record date, there were 297,613,225 HeartWare CDIs entitled to give directions to vote at the HeartWare special meeting. Each HeartWare CDI is exchangeable at the option of the HeartWare CDI holder into shares of HeartWare common stock at the ratio of one (1) share of HeartWare common stock for every thirty-five (35) HeartWare CDIs.
 
A majority of shares of HeartWare common stock issued, outstanding and entitled to vote constitutes a quorum for the purpose of considering the proposals. In the event that a quorum is not present at the special meeting, the meeting may be adjourned by the affirmative vote of a majority of shares present or represented at the special meeting, in order to solicit additional proxies.
 
Vote Required (page 32)
 
Adoption of the merger agreement requires the affirmative vote of the holders of a majority of the outstanding shares of HeartWare common stock entitled to vote in connection with the HeartWare special meeting. Because approval is based on the affirmative vote of a majority of outstanding shares entitled to vote, a HeartWare stockholder’s failure to vote, failure to provide its broker or other nominee with voting instructions on how to vote its shares or a HeartWare stockholder’s abstention from voting will have the same effect as a vote “AGAINST” the adoption of the merger agreement.
 
Approval of the proposal to adjourn the HeartWare special meeting, if necessary or appropriate, to permit further solicitation of proxies requires the affirmative vote of the holders of a majority of the shares present in person or represented by proxy and entitled to vote at the HeartWare special meeting. Because approval of such proposal to adjourn is based on the affirmative vote of a majority of shares present or represented, abstentions from voting will have the same effect as a vote “AGAINST” this proposal and the failure by a HeartWare stockholder to vote its shares will not affect the outcome of this proposal. Brokers or other nominees holding shares of HeartWare common stock in “street name” will have the authority to vote the shares in their discretion on the proposal. If any such broker or nominee abstains from voting, such abstention will have the same effect as a vote “AGAINST” this proposal. CDN cannot vote the underlying shares on behalf of holders of HeartWare CDIs without instructions from such holders. An instruction to CDN to abstain on this proposal will have the same effect as a vote “AGAINST” this proposal.
 
Shares Owned by HeartWare Directors and Executive Officers (page 33)

Selected Historical Consolidated Financial Data of Thoratec
 
The following table sets forth Thoratec’s consolidated financial data for the five (5) fiscal years in the period ended January 3, 2009, derived from Thoratec’s audited consolidated financial statements. Thoratec reports on a fifty-two to fifty-three (52-53) week fiscal year, which ends on the Saturday closest to December 31. Accordingly, Thoratec’s fiscal year will periodically contain more or fewer than 365 days. For example, fiscal year 2004 ended January 1, 2005, fiscal year 2005 ended December 31, 2005, fiscal year 2006 ended December 30, 2006, and fiscal year 2007 ended December 29, 2007. Thoratec’s fiscal year 2008 contained 53 weeks and ended on January 3, 2009. In addition, the selected consolidated financial data as of and for the three months ended April 4, 2009 and March 29, 2008 was derived from Thoratec’s unaudited condensed consolidated financial statements. These selected condensed consolidated interim financial data are not necessarily indicative of results to be expected for future interim periods or the entire fiscal year.
 
You should read this information together with “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and with the consolidated financial statements and notes to the consolidated financial statements for the fiscal year ended January 3, 2009 included in Thoratec’s Form 8-K filed with the SEC on June 11, 2009 and in Thoratec’s Form 10-Q for the quarterly period ended April 4, 2009 each of which is incorporated by reference in this proxy statement/prospectus.

Cautionary Statement Regarding Forward-Looking Statements
 
This proxy statement/prospectus and the documents incorporated by reference herein contain a number of forward-looking statements, including statements about the financial condition, results of operations, earnings outlook, prospects, business strategies, operating efficiencies or synergies, competitive positions, growth opportunities for existing products and the plans and objectives of management concerning Thoratec, HeartWare and the combined company and may include statements for the period following the completion of the mergers. We intend these forward-looking statements to be covered by the safe harbor provided by the Private Securities Litigation Reform Act of 1995. You can find many of these statements by looking for words such as “plan,” “believe,” “expect,” “intend,” “anticipate,” “estimate,” “project,” “potential,” “possible” or other similar expressions.
 
The forward-looking statements involve certain risks and uncertainties. The ability of either HeartWare or Thoratec to predict results or the actual effects of its plans and strategies, or those of the combined company, is subject to inherent uncertainty. Factors that may cause actual results or earnings to differ materially from such forward-looking statements include those beginning on page 25 under the section entitled “Risk Factors”, as well as, among others, the following:
 
  •  those discussed and identified in public filings with the SEC made by HeartWare or Thoratec from time to time;
 
  •  completion of the mergers is dependent on, among other things, receipt of HeartWare stockholder and regulatory approvals, the timing of which cannot be predicted with precision and which may not be received at all;
 
  •  the mergers may be more expensive to complete than anticipated, including as a result of unexpected factors or events;
 
  •  the integration of HeartWare’s business and operations with those of Thoratec may take longer than anticipated, may be more costly than anticipated and may have unanticipated adverse results relating to HeartWare’s or Thoratec’s existing businesses;
 
  •  the anticipated cost savings and other synergies of the mergers may take longer to be realized or may not be achieved in their entirety, and attrition in key customer and other relationships as a result of the mergers may be greater than expected;
 
  •  the ability to attract and retain qualified personnel;
 
  •  responses by competitors of HeartWare and Thoratec to the mergers;
 
  •  decisions to restructure, divest or eliminate business units or otherwise change the business mix of either company;
 
  •  the risk of new and changing regulations and/or regulatory actions in the U.S. and internationally;
 
  •  adverse general domestic and international economic conditions;
 
  •  the extent and duration of continued and new economic and market disruptions as well as the effect of governmental regulatory proposals to address these disruptions;
 
  •  the ability to obtain and maintain regulatory approval of Thoratec and HeartWare products for sale in the U.S. and internationally;
 
  •  the results and timing of clinical trials by Thoratec and HeartWare;
 
  •  reimbursement policies and decisions by government agencies and third-party payors;
 
  •  competing therapies that may currently, or in the future, be available to heart failure patients;
 
  •  plans to develop and market new products and the rate of market penetration of new products;
 
  •  risks relating to the protection of, and challenges to, intellectual property rights; and
 
  •  the exposure to litigation, including the possibility that litigation relating to the merger agreement and transactions contemplated thereby could delay or impede the completion of the merger.

You should understand that forward-looking statements are subject to assumptions and uncertainties and that various factors unknown to either Thoratec or HeartWare at this time, in addition to those discussed elsewhere in this proxy statement/prospectus and in the documents referred to or incorporated by reference in this proxy statement/prospectus, could affect the future results of the combined company following the mergers and could cause results to differ materially from those expressed in or implied by these forward-looking statements. The actual results, performance or achievement of Thoratec following the mergers could differ significantly from those expressed in, or implied by, our forward-looking statements. In addition, any of the events anticipated by our forward-looking statements might not occur, and if they do occur, we cannot predict what impact they might have on the results of operations and financial condition of Thoratec following the mergers. You are cautioned not to place undue reliance on these statements, which speak only as of the date of this document or the date of any document incorporated by reference in this document.
 
All subsequent written and oral forward-looking statements concerning the mergers or other matters addressed in this document and attributable to HeartWare or Thoratec or any person acting on their behalf are expressly qualified in their entirety by the cautionary statements contained or referred to in this document. Except to the extent required by applicable law or regulation, HeartWare and Thoratec undertake no obligation to update these forward-looking statements to reflect events or circumstances after the date of this document or to reflect the occurrence of unanticipated events.

RISK FACTORS
 
In deciding whether to vote in favor of the adoption of the merger agreement, you should consider the matters described below, as well as all of the information that we have included in this proxy statement/prospectus and its annexes and all of the information included in the documents we have incorporated into this proxy statement/prospectus by reference, especially the other risks described in Thoratec’s report on Form 10-K filed with the SEC on February 27, 2009, and in HeartWare’s report on Form 10-K filed with the SEC on February 26, 2009. See the section entitled “Where You Can Find More Information” beginning on page 127 of this proxy statement/prospectus and the matters addressed in “Cautionary Statement Regarding Forward-Looking Statements” beginning on page 23 of this proxy statement/prospectus.
 
The risks and uncertainties described below and in Thoratec’s and HeartWare’s Form 10-K reports referred to above are not the only risks that Thoratec and HeartWare face. Additional risks and uncertainties not currently known to Thoratec or HeartWare or that Thoratec or HeartWare currently deem immaterial also may impair the business operations of Thoratec, HeartWare or the combined company.
 
Risks Related to the Mergers
 
Because the market price of Thoratec common stock will fluctuate, HeartWare stockholders cannot be sure of the market value of the shares of Thoratec common stock that they will receive.
 
The market price of both Thoratec and HeartWare common stock will fluctuate after the date of this proxy statement/prospectus and the market price of Thoratec common stock will likely vary at the closing of the merger from the $26.25 per share price used to determine the number of shares of Thoratec common stock that holders of HeartWare common stock will receive in the merger, the price of Thoratec common stock as of the date of this proxy statement/prospectus and the price of Thoratec common stock as of the date of the HeartWare special meeting. The specific dollar value of Thoratec common stock that HeartWare stockholders will receive upon completion of the merger will depend on the market value of Thoratec common stock at that time.
 
Fluctuations in the market price of Thoratec and HeartWare common stock may be the result of general market and economic conditions, changes in the business, operations or prospects of Thoratec or HeartWare, market assessments of the likelihood that the merger will be completed and the timing of closing of the merger, regulatory considerations and other factors independent of the merger. In addition to the adoption of the merger agreement by HeartWare stockholders at the special meeting, completion of the merger is subject to the expiration or termination of the waiting period under the HSR Act as such waiting period has been extended by the FTC’s request for additional information received on March 26, 2009, and the satisfaction of other conditions that may not occur until some time after the special meeting. See “The Merger Agreement — Conditions to the Obligations of Each Party to Consummate the Merger,” “— Conditions to the Obligations of Thoratec and Merger Subsidiary to Consummate the Merger,” “— Conditions to the Obligations of HeartWare to Consummate the Merger” and “— Conditions to the Obligations of Each Party to Consummate the Second Merger” beginning on page 98 of this proxy statement/prospectus. As a result, at the time of the HeartWare special meeting, HeartWare stockholders will not know the precise dollar value of the stock portion of the merger consideration they will be entitled to receive upon completion of the merger.
 
The merger consideration is valued in U.S. dollars and fluctuations in exchange rates between the U.S. dollar and the Australian dollar could affect the value, in Australian dollars, of the merger consideration to be received by HeartWare stockholders and holders of HeartWare CDIs in the merger.
 
The cash portion of the merger consideration payable to HeartWare stockholders in the merger will be paid by Thoratec in U.S. dollars. Also, the shares of Thoratec common stock payable to HeartWare stockholders in the merger have been valued using a market price calculated in U.S. dollars, and the value of the cash portion of the merger consideration payable to HeartWare CDI holders has been calculated in U.S. dollars. In addition, the shares of Thoratec common stock received by HeartWare CDI holders as merger consideration will not be listed in Australia with ASX or otherwise, and the market price of such shares on The NASDAQ Global Select Market will be denominated in U.S. dollars. As a result, fluctuations in exchange rates between the U.S. dollar and the


25


Table of Contents

Australian dollar may materially and adversely affect the value, in Australian dollars, of any cash and Thoratec common stock received by Australian holders of HeartWare common stock or HeartWare CDIs in the merger.
 
While the market price of Thoratec common stock will fluctuate, the market price of Thoratec common stock payable to HeartWare stockholders in the merger is subject to specified maximum and minimum values. If the market price exceeds the maximum value, the stock portion of the merger consideration payable to HeartWare stockholders may be reduced. If the market price falls below the minimum value, HeartWare may terminate the merger agreement or Thoratec may elect to increase the number of shares of Thoratec stock payable to HeartWare stockholders.
 
The number of shares of Thoratec common stock to be received by holders of HeartWare common stock in the merger as part of the merger consideration has been fixed at 0.6054 of a share of Thoratec common stock for each share of HeartWare common stock. However, if the volume weighted average of the per share closing prices of Thoratec common stock on NASDAQ for the twenty (20) consecutive trading days ending on and including the fifth (5th) trading day prior to, but not including, the closing date is equal to or exceeds 130% of $26.25, the Thoratec per share price used to determine the merger consideration, then Thoratec may reduce the number of shares of Thoratec common stock payable in the merger such that the value of the stock portion of the merger consideration at closing is equal to 130% of the value of the stock consideration at the signing of the merger agreement. If the value of the stock portion of the merger consideration at closing is reduced to equal 130% of the value of the stock consideration used to determine the merger consideration, the maximum value of the Thoratec common stock consideration that you would be entitled to receive as consideration in the merger would be 130% of the value of the stock consideration used to determine the merger consideration at signing, regardless of the actual value of Thoratec common stock at the closing.
 
In addition, if the same volume weighted average price described above is equal to or less than 70% of $26.25, then HeartWare will have an option to terminate the merger agreement unless Thoratec elects to increase the number of shares of Thoratec common stock payable in the merger such that the value of the stock portion of the merger consideration at closing is equal to 70% of the value of the stock consideration used to determine the merger consideration at signing. Thoratec’s ability to increase the stock portion of the merger consideration is subject to a requirement that, if an increase in the stock portion of the consideration would require Thoratec to issue more than 19.9% of its outstanding shares of common stock and would therefore require the approval of Thoratec’s shareholders under The NASDAQ Stock Market Marketplace Rule 5635 (formerly The NASDAQ Stock Market Marketplace Rule 4350), Thoratec shall increase the cash portion of the consideration payable to HeartWare stockholders instead with respect to any increase above the 19.9% threshold.
 
In determining whether to exercise HeartWare’s right to terminate the merger agreement, the HeartWare directors will take into account the facts and circumstances existing at that time with a view to determining whether they continue to believe that the merger remains advisable and in the best interests of HeartWare’s stockholders. In making its determination, the HeartWare directors will consult with HeartWare’s management team, as well as its outside legal and financial advisors, and expects to consider, among other things (i) the extent of the decline in Thoratec’s average stock price during the measurement period below $18.38 per share, (ii) the perceived reasons for the decline, including whether the reasons are particular to Thoratec or apply to the medical device industry generally (including taking into account whether the shares of similarly situated companies to Thoratec have suffered a similar decline) and (iii) whether the price decline is likely to be short-term or long-term in nature. In connection with its determination, the HeartWare directors also expect to consider whether, following HeartWare’s election to exercise its right to terminate the merger agreement, Thoratec is likely to elect to increase the number of shares of Thoratec common stock payable in the merger such that the per share value of the Thoratec common stock payable in the merger, as of the effective time of the merger, is equal to $18.38 (70% of the value of the aggregate Thoratec stock consideration payable in the merger, calculated using the $26.25 price per share of Thoratec common stock used to determine the stock portion of the merger consideration), and to review the factors described under the heading “The Merger — HeartWare’s Reasons for the Merger and Recommendation of the HeartWare Board of Directors” beginning on page 55, particularly the factors described under “Strategic Advantages,” “HeartWare’s Business Conditions and Prospects,” “Thoratec’s Business Conditions and Prospects,” and “Tax Treatment”. The HeartWare directors are cognizant of their fiduciary duties to the HeartWare stockholders in connection with the foregoing determination, and intend to inform themselves of all material information reasonably available to them at that time and to exercise due care in their deliberations before determining

whether to exercise their right to terminate the merger agreement in these circumstances. After the HeartWare board of directors determines, based on the facts and circumstances existing at that time, whether to exercise its right to terminate the merger agreement, HeartWare will promptly notify its stockholders of such determination by issuing a press release announcing such determination, including the basis for the HeartWare board of directors’ determination, as well as filing such press release with the SEC on Form 8-K.
 
Because this determination may be made by HeartWare directors after the HeartWare special meeting has occurred, in determining whether to vote to adopt the merger agreement, HeartWare stockholders should be mindful that the per share value of the Thoratec common stock they receive in the merger could, as of the effective time of the merger, be less than $18.38, with the result that the value of the aggregate merger consideration payable for each share of HeartWare common stock, as of the effective time of the merger, could be less than $25.43 per share, i.e. $18.38 multiplied by the 0.6054 shares of Thoratec common stock payable in the merger plus $14.30 in cash, (as compared to a value of $30.19 per share of HeartWare common stock as of February 12, 2009, the date of execution of the merger agreement).
 
The mergers may be fully taxable to HeartWare stockholders for U.S. federal income tax purposes.
 
If the second merger is not completed, either in accordance with the terms of the merger agreement or otherwise, or if the mergers fail to qualify as a reorganization for U.S. federal income tax purposes (including if the IRS successfully challenges the treatment of the mergers as a reorganization), the receipt of shares of HeartWare common stock and cash for shares of Thoratec common stock in the merger will be fully taxable to HeartWare stockholders for U.S. federal income tax purposes.
 
Pursuant to the merger agreement, the second merger will not be completed, and the merger will be structured as a fully taxable transaction to HeartWare stockholders for U.S. federal income tax purposes, if the condition described in the first paragraph under the section entitled “The Merger — Material U.S. Federal Income Tax Consequences — Transaction Structure” beginning on page 72 of this proxy statement/prospectus is not satisfied. Whether that condition is met will depend on the trading values of Thoratec common stock during the last trading session closing before the effective time of merger. The trading value of Thoratec common stock will fluctuate prior to the merger. Accordingly, we cannot assure you that the second merger will occur or that the transaction will not be fully taxable to you. As a result, in deciding whether to vote to adopt the merger agreement, you should consider the possibility that the transaction will be structured as a fully taxable transaction for U.S. federal income tax purposes because the condition described in the first paragraph under the section entitled “The Merger — Material U.S. Federal Income Tax Consequences — Transaction Structure” beginning on page 72 of this proxy statement/prospectus is not satisfied. You will not be entitled to change your vote or to vote again in the event that the stock value condition is not satisfied and the transaction is structured as a fully taxable transaction for U.S. federal income tax purposes.
 
Assuming an effective stock price of $26.46 of Thoratec common stock, which was the per share closing price on July 2, 2009, and subject to the discussion under “The Merger — Material U.S. Federal Income Tax Consequences” beginning on page 71, the transactions contemplated by the merger agreement would be structured to qualify as a “reorganization” for U.S. federal income tax purposes.
 
HeartWare stockholders are strongly urged to consult their tax advisors to determine the specific tax consequences to them of the merger and the second merger, including any U.S. federal, state or local, or non-U.S. or other tax consequences. For more information, see “The Merger — Material U.S. Federal Income Tax Consequences” beginning on page 71 of this proxy statement/prospectus.
 
The merger may result in a gain that may be fully taxable to Australian resident holders of shares of HeartWare common stock to the extent that scrip-for-scrip roll-over relief is not available.
 
A gain on receipt of replacement Thoratec common stock under the merger contemplated by the merger agreement may be subject to Australian income tax to HeartWare shareholders that are resident of Australia for Australian tax purposes to the extent scrip-for-scrip roll-over relief is not available.
 
HeartWare has sought a ruling from the Australian tax authorities to confirm the Australian tax consequences for HeartWare shareholders that are resident of Australia, hold their HeartWare common stock on capital account and have their shares of HeartWare common stock cancelled under the merger contemplated in the merger agreement.

Thoratec and HeartWare may not be able to obtain required governmental and regulatory approvals for completing the merger in a timely manner or at all.
 
Under the HSR Act, the merger may not be consummated unless certain regulatory filings have been submitted to the FTC and the Antitrust Division of the Department of Justice, which we refer to as the Antitrust Division, and certain waiting period requirements have been satisfied. The FTC and the Antitrust Division frequently scrutinize the legality under the antitrust laws of transactions like the merger. At any time before the completion of the merger, the FTC or the Antitrust Division could take any action under the antitrust laws it deems necessary or desirable in the public interest, including seeking to enjoin the completion of the merger, seeking the divestiture of substantial assets of Thoratec or HeartWare or seeking operating restrictions on the business of Thoratec or HeartWare or the combined company following the closing. Neither Thoratec nor HeartWare is required to agree to any divestiture of assets or restrictions on its business in order to secure approval of the merger by antitrust authorities. In addition, certain private parties as well as state attorneys general and other antitrust authorities may challenge or delay the transaction under antitrust laws under certain circumstances. On March 26, 2009, HeartWare and Thoratec each received a request for additional information from the FTC. The effect of the second request is to extend the waiting period imposed by the HSR Act until thirty (30) days after HeartWare and Thoratec have substantially complied with the second request, unless that period is extended voluntarily by the parties or terminated sooner by the FTC. The parties have substantially complied with the second request and are waiting for a final determination from the FTC. We cannot assure you that the merger will not be delayed as a result of antitrust review or that a challenge to the merger on antitrust grounds will not be made, or, if such a challenge is made, what the result will be. The review of the merger by the FTC or the Antitrust Division and any such challenge could significantly delay or prevent the consummation of the merger and, in the event that Thoratec and HeartWare agree to any divestiture or operating restrictions, could have an adverse impact on the financial condition and results of operations of the combined company following the closing.
 
The pro forma condensed combined financial statements and other pro forma information included in the proxy statement/prospectus are presented for illustrative purposes only and may not be an indication of the combined company’s financial condition or results of operations following the transaction.
 
The pro forma condensed combined financial statements and other pro forma information contained in this proxy statement/prospectus are presented for illustrative purposes only and may not be an indication of the combined company’s financial condition or results of operations following the merger. The pro forma condensed combined financial statements have been derived from the historical consolidated financial statements of Thoratec and HeartWare and adjustments and assumptions have been made regarding the combined company after giving effect to the merger. The information upon which these adjustments and assumptions have been made is preliminary, and these kinds of adjustments and assumptions are difficult to make with accuracy. Moreover, the pro forma condensed combined financial statements and other pro forma information do not reflect all costs that are expected to be incurred by the combined company in connection with the merger. For example, the impact of any incremental costs incurred in integrating the two companies is not reflected in the pro forma condensed combined financial statements and other pro forma information. As a result, the actual financial condition and results of operations of the combined company following the merger may not be consistent with, or evident from, the pro forma condensed combined financial statements and other pro forma information.
 
The assumptions used in preparing the pro forma condensed combined financial information may not prove to be accurate, and other factors may affect the combined company’s financial condition or results of operations following the transaction.
 
Any decline or potential decline in the combined company’s financial condition or results of operations may cause significant variations in the stock price of the combined company.

Thoratec and HeartWare may not realize the benefits they expect from the merger because of risks associated with integration and other challenges.
 
Thoratec’s failure to meet the challenges involved in successfully integrating the operations of HeartWare with those of Thoratec, or to otherwise realize any of the anticipated benefits of the merger, could harm the results of operations of Thoratec following the closing. The benefits of the merger anticipated by Thoratec and HeartWare are based on projections and assumptions, not actual experience, and assume a successful integration. Thoratec’s realization of the benefits of the merger will depend, in part, on the timely and successful integration of technology, operations and personnel. The integration of the companies is a complex, time-consuming and expensive process that could disrupt the businesses of Thoratec and HeartWare, even with proper planning and implementation, and will require significant management attention and resources. Some of the challenges involved in integrating the businesses of Thoratec and HeartWare include:
 
  •  integrating information, communications and other systems and reconciling logistics, marketing and administration methods;
 
  •  maintaining employee morale, retaining key employees and integrating the business cultures of both companies;
 
  •  preserving important strategic and customer relationships;
 
  •  coordinating, combining and consolidating operations, relationships and facilities, which may be subject to additional constraints imposed by geographic distance, local laws and regulations;
 
  •  integrating the companies’ internal control over financial reporting and disclosure controls and procedures and creating uniform standards, controls, procedures, policies and information systems; and
 
  •  minimizing the diversion of management’s attention from ongoing business concerns.
 
Thoratec may not successfully integrate the operations of Thoratec and HeartWare in a timely manner, or at all, and the combined company may not realize the anticipated benefits of the merger to the extent, or in the timeframe, anticipated. In addition to the integration risks discussed above, Thoratec’s ability to realize the benefits of the merger could be adversely impacted by practical or legal constraints on its ability to combine operations or by unknown liabilities associated with the merger and the combined operations. A failure by Thoratec to successfully integrate the operations of Thoratec and HeartWare or otherwise to realize any of the anticipated benefits of the merger could cause an interruption of, or a loss of momentum in, the activities of the combined company and could seriously harm Thoratec’s financial position and results of operations. In addition, the overall integration of the two companies may result in unanticipated problems, expenses, liabilities, competitive responses, loss of important third-party relationships and diversion of management’s attention, and may cause Thoratec’s stock price to decline significantly.
 
Whether or not the merger is completed, the pendency of the merger may cause disruptions in the business of HeartWare or Thoratec which could have material adverse effects on each company’s or the combined company’s business and operations.
 
Whether or not the merger is completed, Thoratec’s and HeartWare’s customers, in response to the announcement of the merger, may delay or defer purchase decisions, which could have a material adverse effect on the business of either company or, if the merger is completed, the combined company. Additionally, HeartWare may lose certain key suppliers as a result of the merger, which, if the merger is completed, could adversely affect the business of the combined company. Current and prospective HeartWare employees may experience uncertainty about their future roles with the combined company. Any failure by HeartWare to attract, retain and motivate executives and key management, sales, marketing and technical personnel during the period prior to the completion of the merger could seriously harm its business, as well as the business of the combined company.
 
Failure to complete the merger could negatively impact the stock price and the future business and financial results of Thoratec and HeartWare.
 
Completion of the merger is subject to a number of closing conditions, including the expiration or termination of any applicable waiting period under the HSR Act and adoption of the merger agreement by HeartWare’s stockholders and those closing conditions may not be satisfied on a timely basis or at all. If the merger is not


29


Table of Contents

completed, the price of HeartWare and Thoratec common stock may decline. In addition, if the merger is not completed, Thoratec and HeartWare may be subject to a number of material risks, including the following:
 
  •  Thoratec and HeartWare would not realize any anticipated benefits from being a part of a combined company;
 
  •  HeartWare may be required to pay a termination fee of either $11.3 million or $5.0 million if the merger agreement is terminated under certain circumstances (see “The Merger Agreement — Termination Fee” beginning on page 101 of this proxy statement/prospectus);
 
  •  Thoratec and HeartWare may be subject to litigation related to any failure to complete the merger, which could require substantial time and resources to resolve;
 
  •  the market price of HeartWare common stock may be adversely affected to the extent the market price reflects an assumption that the merger will be completed;
 
  •  HeartWare may not be able to find another buyer willing to pay an equivalent or higher price in an alternative transaction than the price to be paid by Thoratec in the merger;
 
  •  Thoratec and HeartWare will be required to pay certain costs relating to the merger, such as legal, accounting, financial advisor and printing fees whether or not the merger is completed; and
 
  •  matters relating to the merger (including integration planning) require substantial commitments of time and resources by Thoratec and HeartWare management, which could otherwise have been devoted to other opportunities that may have been beneficial to Thoratec and HeartWare.
 
Some directors and executive officers of HeartWare have interests in the merger that differ from the interests of HeartWare stockholders that may influence these directors and executive officers to support the mergers.
 
Certain of HeartWare’s directors and executive officers have financial interests in the merger that are different from, or in addition to, the interests of HeartWare stockholders. The members of the HeartWare board of directors were aware of and considered these interests, among other matters, in evaluating and negotiating the merger agreement and the merger, and in recommending to HeartWare stockholders that the merger agreement be adopted. Please see “The Merger — Interests of HeartWare Directors and Executive Officers in the Mergers,” beginning on page 65.
 
The merger agreement limits HeartWare’s ability to pursue alternatives to the merger.
 
The merger agreement contains “no shop” provisions that, subject to limited exceptions, limit HeartWare’s ability to discuss, facilitate or commit to competing third-party proposals to acquire all or a significant part of the company. These provisions might discourage a potential competing acquiror that might have an interest in acquiring all or a significant part of HeartWare from considering or proposing that acquisition even if it were prepared to pay consideration with a higher per share market price than that proposed in the merger, or might result in a potential competing acquiror’s proposing to pay a lower per share price to acquire HeartWare than it might otherwise have proposed to pay. HeartWare can consider and participate in discussions and negotiations with respect to an alternative proposal so long as the HeartWare board of directors determines in good faith (after consultation with outside legal counsel) that failure to take such action would reasonably be expected to be inconsistent with its fiduciary duties to HeartWare stockholders under applicable law.
 
The market price for Thoratec common stock may be affected by factors different from those affecting the market price of HeartWare common stock. In addition, holders of Thoratec common stock have different rights as shareholders than holders of HeartWare common stock.
 
If the merger is completed, holders of HeartWare common stock will become holders of Thoratec common stock. Thoratec’s business differs from HeartWare’s business, and Thoratec’s results of operations and the market price of Thoratec common stock may be affected by factors different from those currently affecting the results of operations of HeartWare and the market price of HeartWare common stock. In addition, the results of operations of the combined company and the market price of the combined company’s common stock may be affected by factors different from those currently affecting either Thoratec or HeartWare. For a discussion of the businesses of Thoratec and HeartWare and of certain factors to consider in connection with those businesses, see the documents incorporated by reference in this proxy statement/prospectus and referred to under “Where You Can Find More Information” beginning on page 127.

Table of Contents

 
In addition, holders of shares of Thoratec common stock will have different rights as Thoratec shareholders than the rights they had as HeartWare stockholders before the merger. For a detailed comparison of the rights of Thoratec shareholders compared to the rights of HeartWare stockholders, see “Comparison of Rights of Shareholders of Thoratec and Stockholders of HeartWare” beginning on page 112 of this proxy statement/prospectus.
 
HeartWare stockholders, as a group, will have reduced ownership and voting interests after the merger and will exercise less influence over management of Thoratec than they currently exercise over management of HeartWare.
 
After the effective time of the merger, HeartWare stockholders will own, as a group, in the aggregate a significantly smaller percentage of Thoratec than they currently own of HeartWare. Immediately following the merger, former stockholders of HeartWare are expected to own approximately 9.6% of the outstanding shares of Thoratec common stock, based on the number of shares of HeartWare common stock and Thoratec common stock outstanding on the record date. Consequently, as a general matter, HeartWare stockholders, as a group, will have reduced ownership and voting interests in Thoratec following the merger than they owned of HeartWare prior to the merger and, as a result, they will have less influence over the management and policies of Thoratec than they currently exercise over the management and policies of HeartWare.
 
Thoratec will incur significant transaction, integration and restructuring costs in connection with the merger.
 
Thoratec and HeartWare expect to incur significant costs associated with transaction fees and other costs related to the merger. Specifically, as disclosed in prior public filings, Thoratec expects to incur total non-recurring charges associated with the transaction of approximately $15.0 million to $20.0 million. In addition, Thoratec will incur integration and restructuring costs following the completion of the merger as it integrates the business of HeartWare with Thoratec. Although Thoratec expects that the realization of efficiencies related to the integration of the businesses will offset incremental transaction, integration and restructuring costs over time, we cannot assure you that this net benefit will be achieved in the near term or at all.
 
THE HEARTWARE SPECIAL MEETING
 
HeartWare is furnishing this proxy statement/prospectus to HeartWare stockholders as of the HeartWare record date as part of the solicitation of proxies by the HeartWare board of directors for use at the HeartWare special meeting, including any postponement or adjournment of the meeting. Together with this document, HeartWare is also sending its stockholders a notice of the special meeting and a form of proxy that is solicited by the HeartWare board of directors.
 
Date, Time and Place of the Special Meeting
 
The HeartWare special meeting will be held on • , 2009, at • , U.S. Eastern time ( • , Australia Eastern Standard Time on • , 2009), at • .
 
Purpose of the Special Meeting
 
At the HeartWare special meeting, HeartWare stockholders will be asked to:
 
1. consider and vote upon a proposal to adopt the merger agreement; and
 
2. consider and vote upon a proposal to adjourn the HeartWare special meeting, if necessary or appropriate, to permit further solicitation of proxies if there are not sufficient votes at the time of the HeartWare special meeting to adopt the merger agreement.
 
The HeartWare board of directors has approved and declared the advisability of the merger agreement and has determined that the merger and the other transactions contemplated by the merger agreement are fair to and in the best interests of HeartWare and its stockholders and recommends that HeartWare stockholders vote “FOR” the adoption of the merger agreement and “FOR” the proposal to adjourn the HeartWare special meeting, if necessary or appropriate, to permit further solicitation of proxies.

Record Date; Shares Entitled to Vote; Quorum
 
Only holders of record of HeartWare common stock at the close of business, U.S. Eastern time on June 25, 2009 (7:00 a.m., Australia Eastern Standard Time on June 26, 2009), the HeartWare record date for the HeartWare special meeting, are entitled to notice of, and to vote at, the HeartWare special meeting and any adjournment or postponement of it. On the HeartWare record date, 8,924,351 shares of HeartWare common stock, including shares represented by HeartWare CDIs, were issued and outstanding and held by approximately 1,021 holders of record. Stockholders who hold shares in the form of HeartWare CDIs or in “street name” should follow the procedures set forth under the heading “The HeartWare Special Meeting — Voting of Proxies” beginning on page 33.
 
Holders of HeartWare CDIs at the close of business, U.S. Eastern time on June 25, 2009 (7:00 a.m., Australia Eastern Standard Time on June 26, 2009), the HeartWare record date for the HeartWare special meeting, are entitled to notice of, and to direct CDN to vote the underlying shares of HeartWare common stock on their behalf in connection with the HeartWare special meeting and any adjournment or postponement of it by following the procedures set forth under the heading “The HeartWare Special Meeting — Voting of Proxies” beginning on page 33. Holders of HeartWare CDIs cannot vote their CDIs in person at the special meeting unless such HeartWare CDI holders have completed the conversion of their HeartWare CDIs into shares of HeartWare common stock prior to the record date for the HeartWare special meeting set forth above. CDN, on behalf of the holders of HeartWare CDIs, will vote the underlying shares of HeartWare common stock represented by the HeartWare CDIs on an aggregate basis by (i) determining the total number of HeartWare CDIs “FOR” each proposal, (ii) determining the total number of HeartWare CDIs “AGAINST” each proposal, (iii) determining the total number of HeartWare CDIs abstaining from voting on each proposal, (iv) applying the ratio of one (1) share of HeartWare common stock for every thirty-five (35) HeartWare CDIs and (v) submitting the resultant number of shares of HeartWare common stock “FOR” each proposal and “AGAINST” each proposal and the number of shares abstaining from voting on each proposal, as appropriate.
 
A quorum will be present at the HeartWare special meeting if a majority of the shares of HeartWare common stock issued and outstanding, including shares represented by HeartWare CDIs, on the HeartWare record date and entitled to vote at the HeartWare special meeting are represented at the HeartWare special meeting in person or by proxy. Abstentions and broker “non-votes” (described under the heading, “The HeartWare Special Meeting — Voting of Proxies” beginning on page 33) will be treated as present at the HeartWare special meeting for purposes of determining the presence or absence of a quorum for the transaction of all business. In the event that a quorum is not present at the HeartWare special meeting, it is expected that the special meeting will be adjourned to solicit additional proxies, provided that the proposal to adjourn the special meeting has been adopted by the affirmative vote of a majority of shares of HeartWare common stock represented in person or by proxy at the special meeting and entitled to vote thereon, although less than a quorum. Holders of record of HeartWare common stock on the HeartWare record date are entitled to one vote per share on each matter submitted to a vote at the HeartWare special meeting.
 
Vote Required for Approval
 
The adoption of the merger agreement requires the affirmative vote of the holders of a majority of the outstanding shares of HeartWare common stock entitled to vote at the HeartWare special meeting. Because the required vote of HeartWare stockholders is based upon the number of outstanding shares of HeartWare common stock entitled to vote, rather than upon the shares actually voted, the failure by a HeartWare stockholder to appoint a proxy or to vote in person at the HeartWare special meeting, abstentions and any failure by “street name” holders to provide their brokerage firm, bank, trust or other nominee with instructions on how to vote their shares will have the same effect as a vote against the adoption of the merger agreement. If holders of HeartWare CDIs instruct CDN to abstain from voting on their behalf, the shares of HeartWare common stock underlying such HeartWare CDIs will be counted toward a quorum at the HeartWare special meeting. If holders of HeartWare CDIs fail to instruct CDN to vote the shares of HeartWare common stock underlying their HeartWare CDIs on their behalf, the shares of HeartWare common stock underlying such HeartWare CDIs will not be counted toward a quorum at the HeartWare special meeting. Instructions to CDN to abstain from voting or failure to instruct CDN to vote the underlying shares will, however, have the same effect as a vote “AGAINST” the proposal to adopt the merger agreement.


32


Table of Contents

The approval of the proposal to adjourn the HeartWare special meeting, if necessary or appropriate, to permit further solicitation of proxies if there are not sufficient votes at the time of the HeartWare special meeting to adopt the merger agreement requires the affirmative vote of the holders of a majority of the shares present in person or represented by proxy and entitled to vote at the HeartWare special meeting. Because approval of such proposal requires the affirmative vote of a majority of shares present or represented, holders of HeartWare common stock who abstain from voting will have the same effect as a vote against the adoption of the proposal to adjourn the special meeting and failure to vote will have no effect on the outcome of the proposal. Brokers or other nominees holding shares of HeartWare common stock in “street name” who have not received specific instructions from beneficial owners will have the authority to vote the shares in their discretion on the proposal. If any such broker or nominee abstains from voting, such abstention will have the same effect as a vote “AGAINST” the proposal to adjourn the HeartWare special meeting, if necessary or appropriate, in order to solicit additional proxies. CDN cannot vote the underlying shares on behalf of holders of HeartWare CDIs without instructions from such holders. An instruction to CDN to abstain will have the same effect as a vote “AGAINST” the proposal to adjourn the HeartWare special meeting, if necessary or appropriate, in order to solicit additional proxies.
 
Shares Owned by HeartWare Directors, Executive Officers and Affiliates
 
As of the HeartWare record date, the directors and executive officers of HeartWare were entitled to give directions to vote 98,591,115 HeartWare CDIs and, in the case of Mr. Godshall, to vote 2,866 shares of HeartWare common stock, which collectively represented approximately 31.6% of the outstanding shares of HeartWare common stock at that date.
 
In connection with the transactions contemplated by the merger agreement, all but one of the directors on HeartWare’s board of directors and certain executive officers of HeartWare, who collectively beneficially own in the form of HeartWare CDIs (and in the case of Mr. Godshall, in the form of shares of HeartWare common stock), as of the HeartWare record date, approximately 1.6% of the total outstanding shares of HeartWare common stock, and Apple Tree Partners I, L.P., who beneficially owns in the form of HeartWare CDIs, as of the HeartWare record date, approximately 30.0% of the total outstanding shares of HeartWare common stock have entered into separate support agreements dated as of February 12, 2009, to, among other things, vote or give directions to vote their respective shares of HeartWare common stock in favor of the adoption of the merger agreement with Thoratec, subject to the terms and conditions of the support agreements and, subject to certain exceptions, not to dispose of their shares prior to the date of the HeartWare special meeting. See the section entitled “The Support Agreements” beginning on page 109.
 
Voting of Proxies
 
Stockholders of record of shares may vote such shares by attending the HeartWare special meeting and voting their shares in person at the meeting, or by completing the enclosed proxy card, signing and dating it and mailing it in the enclosed postage-prepaid envelope. If a proxy card is signed by a stockholder of record and returned without specific voting instructions, the shares represented by the proxy will be voted “FOR” the proposals presented at the HeartWare special meeting. No proxy voted against the proposal to adopt the merger agreement will be voted in favor of any adjournment.
 
Stockholders whose shares are held in “street name” must follow the instructions they receive from their broker, bank, trust or other nominee in order to have their shares voted. Stockholders who have not received such voting instructions or require further information regarding such voting instructions should contact their broker. Brokers who hold shares of HeartWare common stock in “street name” for a beneficial owner of those shares typically have the authority to vote in their discretion on “routine” proposals when they have not received instructions from beneficial owners. However, brokers are not allowed to exercise their voting discretion with respect to the approval of matters that are “non-routine,” such as adoption of the merger agreement, without specific instructions from the beneficial owner. Broker non-votes are shares held by a broker or other nominee that are represented at the meeting, but with respect to which the broker or other nominee is not instructed by the beneficial owner of such shares to vote on the particular proposal and the broker does not have discretionary voting power on such proposal. Brokers or other nominees holding shares of HeartWare common stock in “street name” will vote shares held by stockholders in “street name” with respect to the proposal to adopt the merger agreement only if such

stockholders provide instructions on how to vote by filling out the voter instruction form sent to them by their broker with this proxy statement/prospectus. Brokers or other nominees holding shares of HeartWare common stock in “street name” who have not received specific instructions from beneficial owners will have the authority to vote the shares in their discretion on the proposal to adjourn the HeartWare special meeting, if necessary or appropriate, to permit further solicitation of proxies.
 
Holders of HeartWare CDIs may give directions to vote the underlying shares of HeartWare common stock by submitting instructions for CDN to vote on behalf of such HeartWare CDI holder at the meeting on each proposal and according to the directions of such HeartWare CDI holder. Holders of HeartWare CDIs can submit voting instructions by completing and mailing the enclosed CDI Voting Instruction Form or by Internet at the website of Computershare, which is www.computershare.com.au. To submit voting instructions by mail, holders of HeartWare CDIs can send the CDI Voting Instruction Form to Computershare, using the enclosed postage-prepaid envelope or by mailing it to Computershare. To submit voting instructions via Computershare’s website, holders of HeartWare CDIs will need their Holder Identification Number or Security Holder Reference Number, which is shown on the enclosed CDI Voting Instruction Form. Instructions on how to fill out the form are set out on the back of the form or on Computershare’s website at www.computershare.com.au. Holders of HeartWare CDIs will be taken to have signed the CDI Voting Instruction Form if instructions are submitted in accordance with the directions on the website www.computershare.com.au. If a holder of HeartWare CDIs is directing CDN to vote on its behalf, the latest time for receipt of CDI Voting Instruction Forms (and any necessary supporting documents) via mail and voting instructions via Internet is • , U.S. Eastern time on • , 2009 ( • , Australia Eastern Standard Time on • , 2009).
 
Revocability of Proxies and CDI Voting Instruction Forms
 
Stockholders of record may revoke their proxy relating to such shares at any time prior to the time it is voted at the meeting. Such stockholders of record may revoke their proxy by:
 
  •  submitting a signed proxy card bearing a later date than the previously submitted proxy card relating to the same shares to HeartWare’s Company Secretary before the taking of the vote at the HeartWare special meeting;
 
  •  submitting a written, signed notice of revocation bearing a later date than the proxy card to HeartWare’s Company Secretary before the taking of the vote at the HeartWare special meeting; or
 
  •  attending the HeartWare special meeting and voting in person (attendance at the HeartWare special meeting will not, in and of itself, revoke a proxy — the stockholder must actually vote in person at the meeting).

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS
 
The following unaudited pro forma condensed combined financial information combines the historical consolidated financial position and results of operations of Thoratec and of HeartWare, after giving effect to the proposed merger. The merger is expected to be accounted for using the acquisition method of accounting. Under the acquisition method of accounting, Thoratec will record all assets acquired and liabilities assumed at their respective acquisition-date fair values. The unaudited pro forma condensed combined balance sheet information gives effect to the merger as if it had occurred on April 4, 2009. The unaudited pro forma condensed combined statement of operations data for the three months ended April 4, 2009 and for the fiscal year ended January 3, 2009, give effect to the merger as if the merger had occurred on December 30, 2007. Because of different fiscal period ends, the unaudited pro forma condensed combined statement of operations data for fiscal year 2008 combines Thoratec’s historical consolidated statement of operations for the fiscal year ended January 3, 2009 and HeartWare’s historical consolidated statement of operations for the fiscal year ended December 31, 2008. Because of different three month period ends, the unaudited pro forma condensed combined balance sheet information and statement of operations data as of and for the first quarter of 2009 combines Thoratec’s historical consolidated balance sheet and statement of operations as of and for the three months ended April 4, 2009 and HeartWare’s historical consolidated balance sheet and statement of operations as of and for the three months ended March 31, 2009.
 
On February 12, 2009, Thoratec and HeartWare entered into the merger agreement. Under the merger agreement, at the effective time of the merger, each share of HeartWare common stock, including shares of common stock represented by HeartWare CDIs, will be converted into the right to receive $14.30 in cash, without interest, and 0.6054 of a share of Thoratec common stock, subject to adjustment as described in “The Merger Agreement — Merger Consideration” beginning on page 83 of this proxy statement/prospectus. Based on the number of shares of HeartWare common stock and shares issuable upon exercise of stock options and other stock-based awards outstanding as of February 12, 2009, and a price of $26.25 per Thoratec common share (the volume weighted average closing price of Thoratec common shares on The NASDAQ Stock Market for the four (4) trading days preceding the execution of the merger agreement), HeartWare stockholders would receive Thoratec common shares having a market value of approximately $141.0 million in the merger and an aggregate of approximately $141.0 million in cash, reflecting a price of $30.19 per share of HeartWare common stock or $0.86 for each HeartWare CDI (based upon the assumed US/AUS exchange rate of 1.5265 provided in the merger agreement). HeartWare common stock is quoted on The NASDAQ Global Market under the symbol “HTWR” and HeartWare CDIs are quoted on ASX under the symbol “HIN”. Thoratec common stock is quoted on The NASDAQ Global Select Market under the symbol “THOR”.
 
The HeartWare board of directors and the Thoratec board of directors have approved the merger agreement. The completion of the merger depends on a number of conditions being satisfied or, where legally permissible, waived. These conditions include, among others, receipt of the requisite approval of HeartWare stockholders, the expiration or termination of the required waiting period under the HSR Act and the absence of legal impediments to the consummation of the merger. We cannot be certain when, or if, the conditions to the mergers will be satisfied or waived, or that the mergers will be completed. For a more complete description of the approval of the merger agreement and the conditions to completion of the mergers, see “The Merger — Background of the Merger,” “The Merger — HeartWare’s Reasons for the Merger and Recommendation of the HeartWare Board of Directors,” “The Merger — Thoratec’s Reasons for the Merger,” “The Merger Agreement — Conditions to the Obligations of Each Party to Consummate the Merger,” “The Merger Agreement — Conditions to the Obligations of Thoratec and Merger Subsidiary to Consummate the Merger,” “The Merger Agreement — Conditions to the Obligations of HeartWare to Consummate the Merger” and “The Merger Agreement — Conditions to the Obligations of Each Party to Consummate the Second Merger”.
 
The unaudited pro forma condensed combined financial statements reflect the estimated merger consideration expected to be transferred, which does not purport to represent what the actual merger consideration transferred will be at the effective time of the merger. In accordance with SFAS No. 141R, as amended, the fair value of equity securities issued as part of the consideration transferred will be measured on the closing date of the merger at the then-current market price. This requirement will likely result in a per share equity component different from the $26.46 assumed in these unaudited pro forma condensed combined financial statements and that difference may be

material. For illustrative purposes only, assuming a then-current market price of Thoratec common stock on the closing date of the merger of between $8.79 (the highest volume weighted average price of Thoratec common stock, subject to adjustments depending on the number of shares of Thoratec common stock reserved for issuance to holders of unvested and outstanding HeartWare incentive options pursuant to the merger agreement as described in “The Merger Agreement — Treatment of Options and Other Equity-Based Awards” beginning on page 87, at which the aggregate amount of stock consideration payable in the merger will be fixed at 19.9% of the already outstanding shares of Thoratec common stock) and $18.38 per share, and assuming that HeartWare elects to terminate the merger agreement as described in “The Merger Agreement — Merger Consideration” beginning on page 83 of this proxy statement/prospectus and Thoratec elects to increase the number of shares of Thoratec common stock payable in the merger such that the per share value of Thoratec common stock payable in the merger, at the effective time, is equal to $18.38 (70% of $26.25, the price per share of Thoratec common stock used to determine the stock portion of the merger consideration), the estimated aggregate merger consideration (including amounts payable to holders of HeartWare restricted stock, options or other equity based awards at the effective time of the merger pursuant to the merger agreement) will be approximately $239.7 million and the related goodwill balance will be approximately $91.2 million. Assuming a then-current market price of Thoratec common stock on the closing date of the merger of $34.13 per share, the estimated aggregate merger consideration (including amounts payable to holders of HeartWare restricted stock, options or other equity based awards at the effective time of the merger) will be approximately $324.3 million and the related goodwill balance will be approximately $175.8 million. A table illustrating the value of the consideration that would be payable, at the effective time of the merger, to holders of HeartWare common stock issued and outstanding immediately prior to the effective time of the merger, including shares of common stock underlying HeartWare CDIs, based on a range of values of Thoratec common stock is described further in “The Merger Agreement — Merger Consideration” beginning on page 83 of this proxy statement/prospectus.
 
The unaudited pro forma condensed combined financial statements and adjustments are based upon available information and assumptions that the management of Thoratec believes reasonably reflect the merger. The merger is dependent upon certain valuations for identifiable purchased intangibles and in-process research and development that have yet to progress to a stage where there is sufficient information for a definitive measurement. The fair value of identifiable intangible assets is determined using the income approach, which starts with a forecast of all the expected future net cash flows. Under the HSR Act and other relevant laws and regulations, there are significant limitations regarding what Thoratec can learn about the specifics of the HeartWare intangible assets prior to the effective time of the merger and any such process will take several months to complete. The estimated intangible asset values and their useful lives could also be impacted by a variety of factors that may become known to Thoratec only upon access to additional information and/or by changes in such factors that may occur prior to the effective time of the merger. These factors include but are not limited to the regulatory, legislative, legal, technological and competitive environments. Accordingly, increased knowledge about these and/or other elements will likely result in a change to the estimated fair value of the HeartWare intangible assets and/or to the estimated weighted-average useful lives from what Thoratec has assumed in the unaudited pro forma condensed combined financial statements and such differences may be material. The combined effect of any such changes could then also result in a significant increase or decrease to Thoratec’s estimate of associated amortization expense. Accordingly, there will be differences between such preliminary estimates and the final acquisition method of accounting for the merger, and these differences could have a material impact on the accompanying unaudited pro forma condensed combined financial statements and the combined company’s future results of operations and financial position.
 
As of the date of this proxy statement/prospectus, Thoratec does not have sufficient information as to the amount, timing and risk of cash flows of all of the HeartWare intangible assets, particularly those assets still in the research and development phase, to calculate the fair value of such intangible assets. Some of the more significant assumptions inherent in the development of intangible asset values, from the perspective of a market participant, include the amount and timing of projected future cash flows (including revenue, cost of sales, research and development costs, sales and marketing expenses and working capital/contributory asset charges), the discount rate selected to measure the risks inherent in the future cash flows and the assessment of the asset’s life cycle and the competitive trends impacting the asset, as well as other factors.

Acquired in-process research and development assets are initially recognized at fair value and are classified as indefinite-lived assets until the successful completion or abandonment of the associated research and development efforts. Accordingly, during the development period after the acquisition date, these assets will not be amortized; instead these assets will be subject to periodic impairment testing that may result in the write-off of all or a portion of the carrying value of these assets. Upon successful completion of the development process for an acquired in-process research and development project, determination as to the useful life of the asset will be made. At that point in time the remaining carrying value of the asset would then be considered a finite-lived intangible asset and Thoratec would begin to amortize the asset.
 
The unaudited pro forma condensed combined financial statements do not include the effects of the costs associated with any restructuring or integration activities resulting from the merger. In addition, the unaudited pro forma condensed combined financial statements do not include the potential realization of any cost savings from operating efficiencies or synergies resulting from the merger, nor do they include any potential incremental revenues and earnings that may be achieved with the combined capabilities of Thoratec and HeartWare.
 
Thoratec shareholders and HeartWare stockholders should read the unaudited pro forma condensed combined financial information in conjunction with Thoratec’s and HeartWare’s audited historical consolidated financial statements, accompanying notes to the consolidated financial statements and the section entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Thoratec’s Form 8-K filed with the SEC on June 11, 2009 and Thoratec’s and HeartWare’s Annual Report on Form 10-K for the fiscal years ended January 3, 2009 and December 31, 2008, respectively, each of which is incorporated by reference into this proxy statement/prospectus. Thoratec shareholders and HeartWare stockholders should also read the unaudited pro forma condensed combined financial information in conjunction with Thoratec’s and HeartWare’s unaudited historical condensed consolidated financial statements, accompanying notes to the condensed consolidated financial statements and the section entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Thoratec’s and HeartWare’s Quarterly Report on Form 10-Q for the quarterly period ended April 4, 2009 and March 31, 2009, respectively, each of which is incorporated by reference into this proxy statement/prospectus.

Notes to Unaudited Pro Forma Condensed Combined Financial Statements
 
1.   Basis of Pro Forma Presentation
 
The unaudited pro forma condensed combined financial statements of Thoratec have been prepared giving effect to the merger between Merger Subsidiary and HeartWare on a historical basis. The unaudited pro forma condensed combined balance sheet information gives effect to the merger as if the merger had occurred on April 4, 2009. The unaudited pro forma condensed combined statement of operations data for the three months ended April 4, 2009 and for the fiscal year ended January 3, 2009, gives effect to the merger as if the merger had occurred on December 30, 2007. The merger has been accounted for in the unaudited pro forma condensed combined financial statements using the acquisition method of accounting in accordance with SFAS No. 141R, Business Combinations, which Thoratec adopted on January 1, 2009, and using the fair value concepts defined in SFAS No. 157, Fair Value Measurements.
 
SFAS No. 141R requires, among other things, that most assets acquired and liabilities assumed be recognized at their fair values as of the acquisition-date and that the fair value of in-process research and development be recorded on the balance sheet regardless of the likelihood of success as of the acquisition-date. In April 2009, the FASB issued FSP SFAS No. 141R-1, Accounting for Assets Acquired and Liabilities Assumed in a Business Combination That Arise from Contingencies, which amends the guidance in SFAS No. 141R to require contingent assets acquired and liabilities assumed in a business combination to be recognized at fair value on the acquisition date if fair value can be reasonably estimated during the measurement period. This guidance is effective for all business acquisitions occurring on or after the beginning of the first annual reporting period beginning on or after December 15, 2008.
 
SFAS No. 157 defines the term “fair value” and sets forth the valuation requirements for any asset or liability measured at fair value, expands related disclosure requirements and specifies a hierarchy of valuation techniques based on the nature of the inputs used to develop the fair value measures. Fair value is defined in SFAS No. 157 as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.” This is an exit price concept for the valuation of the asset or liability. In addition, market participants are assumed to be buyers and sellers in the principal (or the most advantageous) market for the asset or liability. Fair value measurement for an asset assumes the highest and best use by these market participants. As a result of these standards, Thoratec may be required to record assets which are not intended to be used or sold and/or to value assets at fair value measures that do not reflect Thoratec’s intended use of those assets. Many of these fair value measurements can be highly subjective and it is also possible that other professionals, applying reasonable judgment to the same facts and circumstances, could develop and support a range of alternative estimated amounts.
 
Under SFAS No. 141R, acquisition-related transaction costs (i.e., advisory, legal, valuation and other professional fees) and certain acquisition-related restructuring charges are not included as a component of consideration transferred but are accounted for as expenses in the periods in which the costs are incurred. As of April 4, 2009, total remaining transaction costs are estimated to be $14.5 million, with approximately $8.8 million allocable to Thoratec, and approximately $5.5 million allocable to HeartWare. The estimated transaction costs also include $0.2 million related to the issuance of Thoratec shares as stock consideration in the merger.
 
For purposes of these unaudited pro forma condensed combined financial statements, Thoratec has assumed the total preliminary consideration issued and paid in the merger to be approximately $283.0 million, consisting of $141.0 million paid in cash and approximately 5.4 million issued shares of Thoratec common stock valued at the July 2, 2009 share price of $26.46 per share, or $142.0 million.

Total preliminary estimated merger consideration
          $ 283,035  
                 
 
Under the acquisition method of accounting, the total preliminary estimated merger consideration is shown in the table above, and is allocated in the table below to Thoratec’s net tangible and intangible assets and liabilities based on their estimated fair value. For the unaudited pro forma condensed combined financial statements, the preliminary estimated merger consideration is allocated as follows:
 
         
    (In thousands)  
 
Assets as of April 4, 2009 at book value:
       
Cash
  $ 12,592  
Receivable, net
    1,179  
Inventory
    6,685  
Short-term prepaid expenses and other
    926  
Property, plant and equipment, net
    3,464  
Purchased intangibles
    1,010  
Long-term prepaid expenses and other
    289  
Accounts payable and accrued liabilities as of April 4, 2009 at book value
    (5,894 )
Adjustments to:
       
Inventory at the estimated fair value
    1,089  
Estimated fair value for leases
    (240 )
Reversal of HeartWare purchased intangibles
    (1,010 )
Long-term deferred tax asset related to operating loss carry-forwards
    28,881  
Short-term deferred tax liabilities

Notes to Unaudited Pro Forma Condensed Combined Financial Statements — (Continued)
 
The above estimated goodwill is calculated as the difference between the acquisition-date fair value of the consideration expected to be transferred and the values assigned to the assets acquired and liabilities assumed. Estimated goodwill does not include pro forma adjustments for non-recurring items such as transaction costs and compensation payments. Goodwill is not amortized.
 
The estimated consideration expected to be transferred as reflected in these unaudited pro forma condensed combined financial statements does not purport to represent what the actual merger consideration will be when the merger is consummated. In accordance with SFAS No. 141R, the fair value of the equity securities issued as part of the consideration transferred will be measured on the closing date of the merger at the then-current market price. This requirement will likely result in a per share equity component different from the $26.46 assumed in these unaudited pro forma condensed combined financial statements and that difference may be material. For example, the high and low closing price per share of Thoratec’s common stock, as reported by The NASDAQ Global Select Market for the period from the merger agreement date of February 12, 2009 to July 2, 2009 was $30.38 and $20.40, respectively, and if the price per share of Thoratec’s common stock on the closing date of the merger were to be $30.38 or $20.40, the estimated merger consideration would be as follows:
 
                 
        Estimated
        Merger
    Stock Price   Consideration
        (In thousands)
 
High
  $ 30.38     $ 304,084  
Low
  $ 20.40     $ 250,509  
 
An increase or decrease in the merger consideration transferred at the effective time of the merger as described above would be reflected as an adjustment to goodwill in the unaudited pro forma condensed combined balance sheets.

b) Reflects the following estimated acquisition-date fair value adjustments:
 
                 
        Estimated Useful
        Lives (Years)
    (In thousands)

Inventory fair value adjustment
    1,089          
Reversal of HeartWare historical purchased intangibles
    (1,010 )        
 
 
(1) Developed technology assets represent ventricular assist device products that have received required regulatory approvals to enable such products to be marketed or sold to the public and ventricular assist device products that are currently undergoing approved clinical trials in the United States. The estimated fair value of such assets was determined using the income approach using projected discounted cash flows. Acquired developed-technology assets are recognized at fair value at the date of the transaction and are classified as finite-lived intangibles. The useful life of finite-lived intangibles is estimated and amortized over the period the asset is expected to contribute directly or indirectly to future cash flows of Thoratec. The amortized costs will be charged to Thoratec’s combined net income or loss.
 
(2) In-process research and development assets represent ventricular assist device products that are under development and that have not received the required regulatory approvals to enable such products to be marketed or sold to the public or to be used in clinical trials. The estimated fair value of such assets was determined using the income approach using projected discounted cash flows. As of the date of this proxy statement/prospectus, Thoratec does not have sufficient information as to the amount, timing and risk of cash flows to calculate the fair value of all of the in-process research and development intangibles. Accordingly, during the development period after the acquisition date, these assets will not be amortized; instead these assets will be subject to periodic impairment testing. Upon successful completion of the development process for an acquired in-process research and development project, determination as to the useful life of the asset will be made. At that point in time the remaining carrying value of the asset would then be considered a finite-lived intangible asset and Thoratec would begin to amortize the asset.
 
c) Reflects the following tax impacts related to fair value adjustments and loss carry-forwards:
 
         
    (In thousands)
 
Long-term deferred tax asset related to operating loss carry-forwards
  $ 28,881  
Short-term deferred tax liabilities
    430  
Long-term deferred tax liability relating to purchased intangibles and in-process research and development
    67,345  
 
d) Reflects the following impact for severance payments and retention bonus payments to be made to certain HeartWare employees as a result of pre-existing change in control contractual provisions that will become payable at the time the transaction is consummated and which are directly attributable to the transaction:
 
         
    (In thousands)
 
Accrued liabilities
  $ 8,464  
Short-term deferred tax liability
    548  
Long-term deferred tax assets
    5,627  
 
e) Reflects accrued incremental direct and external transaction costs totaling $14.5 million consisting of approximately $8.8 million allocable to Thoratec’s investment banking fees, legal fees and accounting fees and an

estimated $0.2 million associated with stock consideration recorded to additional-paid-in capital and approximately $5.5 million allocable to HeartWare’s legal and investment banking fees and are recorded to accrued liabilities.
 
f) Reflects the following elimination of the impact of the pro forma adjustments on HeartWare’s historical accumulated deficit balance, which is comprised of pre-existing change in control contractual provisions at the time the transaction is consummated, and therefore is directly attributable to the transaction:

Retention bonus and severance payments
  $ (7,032 )
Deferred taxes
    5,079  
Transaction costs
    (5,500 )
 
g) Goodwill is calculated as the difference between the acquisition-date fair value of the merger consideration expected to be issued and paid and the values assigned to the assets acquired and liabilities assumed. Goodwill is not amortized.
 
h) Reflects the reversal of an unrealized gain of $0.9 million, as a result of $110.0 million in short-term investments used in the merger consideration.
 
Pro Forma Adjustments to Condensed Combined Statement of Operations for the Three Months Ended April 4, 2009
 
Significant non-recurring one time charges have not been reflected in the combined statement of operations, including merger-related transaction costs and share-based compensation costs described under the section “Pro Forma Adjustments to Condensed Combined Balance Sheet” above. Additionally, the pro forma statement of operations does not reflect the non-recurring impact on cost of sales as a result of the inventory fair value adjustment.
 
i) Reflects a reduction in interest income of $0.8 million resulting from the use of cash and short-term investments as merger consideration, assuming an interest rate based upon Thoratec’s 2009 historical average interest rate of 2.35%.
 
j) Reflects the reversal of amortization of the historical book value of HeartWare’s purchased intangible assets.
 
k) Reflects incremental amortization expense of $2.5 million for the fair value adjustment related to purchased identified intangible assets.
 
l) Represents a $27,000 amortization of fair value adjustment on operating leases recorded to cost of product sales.
 
m) The $2.8 million tax benefit reflects the tax impact related to the pro forma combined net loss position from Thoratec’s utilization of HeartWare net operating losses, which reduces the combined federal statutory income tax expense and state tax expense.
 
n) Reflects the basic shares of Thoratec common stock to be issued in exchange for HeartWare common stock outstanding at an exchange ratio of 0.6054, or 5.4 million shares. Diluted shares also include the elimination of Thoratec’s common share equivalents as such shares are anti-dilutive for pro forma purposes. Additionally, the weighted average shares of HeartWare at March 31, 2009 are eliminated in the condensed combined pro forma financial statements.
 
Pro Forma Adjustments to Condensed Combined Statement of Operations for the Fiscal Year Ended January 3, 2009
 
Significant non-recurring one time charges have not been reflected in the combined statement of operations, including merger-related transaction costs and share-based compensation costs described under the section “Pro Forma

o) Reflects a reduction in interest income from $141.0 million of cash and short-term investments used as merger consideration, assuming an interest rate based upon Thoratec’s 2008 historical average interest rate of 3.3%.
 
p) Reflects the reversal of amortization of the historical book value of HeartWare’s purchased intangible assets.
 
q) Reflects incremental amortization expense of $10.0 million for the fair value adjustment related to purchased identified intangible assets.
 
r) Represents a $0.1 million amortization of fair value adjustment on operating leases recorded to cost of product sales.
 
s) The $12.9 million tax benefit reflects the tax impact related to the pro forma combined net loss position from Thoratec’s utilization of HeartWare net operating losses, which reduces the combined federal statutory income tax expense and state tax expense.
 
t) Reflects the basic shares of Thoratec common stock to be issued in exchange for HeartWare common stock outstanding at an exchange ratio of 0.6054, or 5.4 million shares. Diluted shares also include the elimination of Thoratec’s common share equivalents as such shares are anti-dilutive for pro forma purposes. Additionally, the weighted average shares of HeartWare at December 31, 2008 are eliminated in the condensed combined pro forma financial statements.
 
3.   Pro Forma Condensed Combined Net Loss Per Share
 
The basic and diluted pro forma condensed combined net loss per common share for the periods presented are based on the weighted average number of common and diluted shares after taking into account the shares issued for the acquisition of HeartWare. Diluted net income per common share reflects the potential dilution that could occur, using the treasury stock method, if securities or other contracts to issue common stock were exercised or converted into common stock. Amounts used in the determination of pro forma basic and diluted net loss per share are as follows:
 
                 
    Three Months Ended
    Fiscal Year Ended
 
    April 4, 2009     January 3, 2009

Thoratec weighted average number of common shares-basic
    56,384       55,097  
Shares issued for HeartWare acquisition
    5,368       5,368  
                 
Pro forma weighted average number of common shares-basic and diluted
    61,752       60,465  
                 
Pro forma net loss per share:
               
Basic
  $ (0.02 )   $ (0.12 )
                 
Diluted
  $ (0.02 )   $ (0.12 )
                 
 
The computation of diluted pro forma net loss per share excludes the effect of common stock options and convertible debt because the effect would be anti-dilutive.

THE MERGER
 
Background to the Merger
 
From time to time, HeartWare’s management and board of directors explore and assess the various strategic alternatives available to HeartWare to strengthen its existing market positions, establish new growth platforms, improve its capital position and deliver increased value to its stockholders. In late 2008, HeartWare retained J.P. Morgan as financial advisor to assist it in evaluating potential transactions, including a potential combination with Thoratec.
 
Thoratec’s management also periodically reviews and analyzes clinical and technological market developments and explores potential strategic alternatives available to Thoratec to enhance shareholder value and facilitate the continued growth of its business and development of its product offerings. The Thoratec board of directors met on August 21, 2008, and, at that meeting, Mr. Gerhard F. Burbach, President and Chief Executive Officer of Thoratec, and other members of Thoratec’s management reviewed a variety of strategic alternatives that might be available to Thoratec in order to potentially enhance the range of products in development or offered by Thoratec. Thoratec management’s review of strategic alternatives included a general discussion of the potential merits of an acquisition of HeartWare. During the meeting, the Thoratec board of directors authorized Mr. Burbach to contact senior management of HeartWare to determine if HeartWare was interested in exploring an acquisition by Thoratec.
 
On September 23, 2008, Mr. Douglas Godshall, President and Chief Executive Officer of HeartWare, and Mr. Burbach both attended the annual scientific meeting of the Heart Failure Society of America in Toronto, Canada. At those meetings, Mr. Burbach informed Mr. Godshall that Thoratec might be interested in exploring the possibility of acquiring HeartWare. Mr. Godshall responded that HeartWare was not seeking a sale at that time but indicated that he would consult with the HeartWare board of directors should Thoratec decide to pursue an acquisition transaction.
 
On September 26, 2008, Mr. Godshall and Mr. Burbach spoke by telephone and agreed to meet at the Cleveland Clinic Conference that was scheduled to occur in mid-October and to further discuss Thoratec’s interest in acquiring HeartWare.
 
On October 17, 2008, Mr. Burbach and Mr. Jon Shear, Vice President Business Development of Thoratec, met with Mr. Godshall and Mr. David McIntyre, Chief Financial Officer and Chief Operating Officer of HeartWare, at the Cleveland Clinic Conference in Cleveland, Ohio. At that meeting, Mr. Burbach again expressed Thoratec’s potential interest in exploring the possibility of acquiring HeartWare. Mr. Burbach and Mr. Shear described the various business segments of Thoratec and the potential benefits to patients that could result from the combination of the two companies. At this meeting, Mr. Burbach and Mr. Godshall discussed whether Apple Tree Partners, HeartWare’s largest stockholder, would be receptive to an acquisition proposal. Mr. Godshall again informed Mr. Burbach that HeartWare was not seeking a sale, and that he was not, at that time, able to respond to Mr. Burbach’s inquiries regarding a potential sale of HeartWare or Apple Tree’s potential response to an acquisition proposal. Mr. Godshall advised Mr. Burbach that he would inform the HeartWare board of directors of Thoratec’s expression of interest.
 
During the week of October 19, 2008, Mr. Godshall had discussions with various members of the HeartWare board of directors regarding Thoratec’s expressed interest in acquiring HeartWare.
 
On November 1, 2008, Thoratec delivered a draft confidentiality agreement to HeartWare that would allow Thoratec access to certain due diligence information concerning HeartWare in the event that the HeartWare board of directors determined to explore a possible business combination transaction with Thoratec.
 
On November 6, 2008, representatives of HeartWare met with representatives of J.P. Morgan and informed J.P. Morgan of HeartWare’s discussions with Thoratec. Around this time, HeartWare also engaged Shearman as its outside legal counsel to advise it in connection with its discussions with Thoratec regarding a possible transaction.
 
The HeartWare board of directors met on November 12, 2008 and November 13, 2008. At those meetings, among other things, members of HeartWare’s senior management team made presentations to the HeartWare board of directors regarding HeartWare’s business and financial performance, and representatives of J.P. Morgan made a presentation of its preliminary financial analyses of HeartWare and Thoratec and a potential transaction. The


49


Table of Contents

HeartWare board of directors discussed whether HeartWare should engage in discussions with Thoratec concerning a possible change of control transaction, actively solicit third parties with respect to a change of control transaction or continue to pursue HeartWare’s long-term strategy as an independent company. The HeartWare board of directors also discussed other aspects of HeartWare, including the status of its U.S. clinical trial and its financing plans. At the conclusion of these meetings, the HeartWare board of directors authorized HeartWare’s senior management team to provide limited summary due diligence information regarding HeartWare to Thoratec and its representatives and to request that Thoratec make a more specific proposal to acquire HeartWare, including a firm indication of Thoratec’s valuation of HeartWare, the form of consideration to be paid and the anticipated timing of a transaction. The HeartWare board of directors also established a sub-committee of the HeartWare board of directors in connection with its consideration of a potential transaction with Thoratec, comprised of Messrs. Godshall, Harrison, Larkin, Stockman and Thomas, which we refer to as the transaction sub-committee.
 
During the period from November 4 through November 14, 2008, HeartWare and Thoratec with the assistance of their respective counsel negotiated the terms of a mutual confidentiality agreement, which the parties entered into on November 14, 2008. The mutual confidentiality agreement contained customary confidentiality provisions and non-solicit provisions and a customary standstill provision for Thoratec.
 
On November 18, 2008, Mr. Burbach and other representatives of Thoratec’s senior management team met with Mr. Godshall, Mr. McIntyre and Mr. Jeffrey LaRose, the Chief Scientific Officer of HeartWare, in New York, New York. At that meeting, HeartWare made a presentation and answered questions regarding certain aspects of its business, including its technology. The HeartWare representatives also advised the Thoratec representatives that the HeartWare board of directors required a firm indication on valuation before further due diligence with respect to HeartWare would be permitted.
 
On December 6, 2008, at a meeting of the Thoratec board of directors, Mr. Burbach and other members of Thoratec’s senior management team presented a preliminary assessment of a potential acquisition of HeartWare. During that meeting, the Thoratec board of directors authorized Mr. Burbach to present a proposal to HeartWare pursuant to which Thoratec would acquire all of the outstanding shares of HeartWare (on a fully diluted basis) for approximately $225.0 million, comprised of 40% cash and 60% shares of Thoratec common stock.
 
On December 8, 2008, Mr. Burbach called Mr. Godshall to inform him that Thoratec was prepared, on a preliminary basis, to pay approximately $225.0 million for all of the outstanding shares of HeartWare (on a fully diluted basis). Mr. Burbach further indicated that Thoratec would propose a mix of consideration consisting of 40% in cash and 60% in shares of Thoratec common stock. Mr. Godshall indicated that he would inform the HeartWare board of directors of Thoratec’s proposal.
 
On December 9, 2008, a meeting of the HeartWare board of directors was held by teleconference to discuss Thoratec’s initial proposal. Following deliberations among the members of the HeartWare board of directors and their advisors, the HeartWare board of directors concluded that the purchase price proposed by Thoratec was inadequate. The HeartWare board of directors did, however, authorize HeartWare’s senior management team to continue discussions with Thoratec and to seek an increase in the purchase price proposed by Thoratec. The HeartWare board of directors also directed HeartWare’s management not to provide any additional due diligence materials to Thoratec before there was agreement between the parties on a purchase price for HeartWare.
 
On December 10, 2008, Mr. Godshall informed Mr. Burbach that the HeartWare board of directors believed the $225.0 million purchase price that had been proposed was inadequate and that the HeartWare board of directors had directed management to discontinue the due diligence on HeartWare until such time as a purchase price for HeartWare was preliminarily agreed upon in principle by the parties. Mr. Godshall further informed Mr. Burbach that HeartWare, at the direction of the HeartWare board of directors, would be pursuing its plan to raise third-party financing in the first quarter of 2009.
 
On December 11, 2008, the Thoratec board of directors met and Mr. Burbach updated the Thoratec board of directors on his discussions with Mr. Godshall. In addition, on December 11, 2008, Mr. Burbach called Mr. Godshall to tell him that the Thoratec board of directors had engaged Banc of America Securities LLC, which we refer to as Banc of America, as its financial advisor in connection with Thoratec’s proposed acquisition of HeartWare, and that

he would contact Mr. Godshall in the near-term following discussions with the Thoratec board of directors and Thoratec’s advisors regarding the proposed transaction.
 
On December 18, 2008, Mr. Godshall and Mr. McIntyre, together with representatives of J.P. Morgan, met by teleconference with Mr. David Smith, the CFO of Thoratec, and Mr. Shear, together with representatives of Banc of America. During this call, Mr. Godshall repeated the position of the HeartWare board of directors regarding the inadequacy of Thoratec’s $225.0 million proposal, and stated that Thoratec would have to propose a significantly higher purchase price in order for the HeartWare board of directors to give any further consideration to a business combination transaction with Thoratec. Following that call, at the direction of senior management of HeartWare and Thoratec, representatives of J.P. Morgan and Banc of America held a follow up meeting by teleconference to discuss their respective preliminary analyses of the valuation of HeartWare.
 
The Thoratec board of directors met again on December 22, 2008, and Mr. Burbach and other members of Thoratec’s senior management team, representatives of Banc of America and Latham, Thoratec’s outside legal counsel, reviewed the current state of negotiations with HeartWare and its advisors for the Thoratec board of directors, and Banc of America provided a preliminary valuation analysis with respect to HeartWare. Following discussion among the Thoratec board of directors and its advisors, the Thoratec board of directors authorized Mr. Burbach to communicate a proposal representing a valuation of HeartWare of $270.0 million (on a fully diluted basis) and indicate that the consideration would take the form of up to 60% shares of Thoratec common stock and approximately 40% cash.
 
On December 23, 2008, Mr. Burbach sent a letter to Mr. Godshall containing a brief overview of Thoratec, summarizing Thoratec’s views on the strategic benefits of a business combination transaction with HeartWare and outlining Thoratec’s preliminary views regarding a proposed transaction structure. The letter indicated a valuation of HeartWare of $270.0 million (on a fully diluted basis) and indicated that the consideration would take the form of up to 60% shares of Thoratec common stock and approximately 40% cash.
 
On December 24, 2008, Mr. Godshall called Mr. Burbach to advise him that HeartWare was not prepared to proceed with the proposed transaction based on a purchase price of $270.0 million. Later that day, Mr. McIntyre contacted Mr. Shear and requested that all confidential information disclosed to date be returned or destroyed pursuant to the terms of the confidentiality agreement executed on November 14, 2008.
 
On December 27, 2008, Mr. Godshall called Mr. Burbach to discuss the terms for the proposed transaction and a structure that might be acceptable to both the HeartWare board of directors and the Thoratec board of directors. Mr. Godshall repeated the position of the HeartWare board of directors regarding the inadequacy of Thoratec’s $270.0 million proposal and that, accordingly, Thoratec needed to propose a higher purchase price, and that while HeartWare was amenable to receiving Thoratec common stock as part of the consideration, the HeartWare stockholders would need protection against a decrease in Thoratec’s stock price during the period between signing a definitive agreement and the closing of a transaction.
 
On December 29, 2008, a meeting of the HeartWare board of directors was held by teleconference. Representatives of Shearman and J.P. Morgan also participated in the meeting. Mr. Godshall updated the HeartWare board of directors on the recent discussions with Thoratec, including the $270.0 million proposal. Mr. Godshall also informed the HeartWare board of directors of potential third-party financing transactions that might be available to HeartWare absent a transaction with Thoratec. The HeartWare board of directors discussed with representatives of Shearman and J.P. Morgan the potential terms for a definitive merger agreement, including various price protection mechanisms in respect of the stock portion of the proposed consideration. The HeartWare board of directors also discussed the need for interim financing in the event of a transaction with Thoratec and the preliminary terms on which Thoratec might provide this interim financing. Following further discussions, the HeartWare board of directors authorized continued discussions with Thoratec, provided that Thoratec would agree to increase the purchase price to approximately $285.0 million.
 
From December 29, 2008 through January 7, 2009, HeartWare and its legal and financial advisors and Thoratec and its legal and financial advisors continued to discuss the material terms of a proposed transaction and during those discussions, agreed to continue negotiations based upon a $282.0 million purchase price for HeartWare. Mr. Burbach and other members of Thoratec’s senior management team met with the Thoratec board

of directors on January 5, January 8 and January 9, 2009, to discuss the material terms of the proposed transaction and the ongoing negotiations with HeartWare and to receive guidance from the members of the Thoratec board of directors on the proposed terms of an acquisition of HeartWare, including the proposed purchase price.
 
On January 11, 2009, representatives of HeartWare’s senior management team, including Mr. Godshall and Mr. McIntyre, met at Latham’s office in San Francisco, California with representatives of Thoratec’s senior management team, including Mr. Burbach and Mr. Smith, and representatives of Shearman, J.P. Morgan, Latham and Banc of America, to discuss the material terms of the proposed transaction, including the terms of an interim loan from Thoratec to HeartWare, and the same participants met again on January 12, 2009 by teleconference to continue their discussion. At those meetings, Thoratec and HeartWare agreed to prepare a non-binding term sheet based on a purchase price of approximately $282.0 million, with the consideration taking the form of 50% shares of Thoratec common stock and 50% cash, and which would include both protection for HeartWare against a decrease in Thoratec’s stock price during the period between signing of a definitive merger agreement and the closing of the merger and a similar protection for Thoratec against an increase in Thoratec’s stock price during the period between the signing of a definitive merger agreement and the closing of the merger.
 
On January 12, 2009, Mr. Godshall and representatives of HeartWare’s senior management team met by teleconference with the transaction sub-committee of the HeartWare board of directors.

The transaction sub-committee unanimously agreed to recommend to the full HeartWare board of directors to proceed with the negotiation of the proposed transaction on the terms outlined during the call. Later that day, the full HeartWare board of directors met by teleconference, at which time the board was informed of the transaction sub-committee’s recommendation. The HeartWare board of directors unanimously agreed with the transaction sub-committee’s recommendation and instructed HeartWare’s senior management team to proceed with negotiations. Later that day, Latham sent a detailed preliminary due diligence request list to Shearman, requesting that HeartWare provide Thoratec and its representatives with certain business, financial, accounting, legal, regulatory and other information.
 
On January 13, 2009, Mr. Burbach and other representatives of Thoratec’s senior management met with the Thoratec board of directors and updated the Thoratec board of directors on the status of negotiations with HeartWare and the material terms of the proposed acquisition of HeartWare that had been preliminarily agreed to at the January 11 and 12, 2009 meetings. The Thoratec board of directors authorized Thoratec’s senior management team to proceed with negotiations with HeartWare based on the terms presented to the Thoratec board of directors. Later that day, HeartWare and Thoratec reached a non-binding agreement in principle on the material terms for the proposed business combination between the two companies and representatives of Shearman and J.P. Morgan met by teleconference with representatives of Latham and Banc of America to discuss the preparation and negotiation of a definitive merger agreement, the ongoing due diligence process and the timing of the proposed transaction. Following that teleconference, HeartWare provided Thoratec with an initial response to its preliminary due diligence request list. In addition, on January 13, 2009, Shearman sent a detailed preliminary due diligence request list with respect to Thoratec to Latham, requesting that Thoratec provide HeartWare and its representatives with certain business, financial, accounting, legal, regulatory and other information.
 
On January 13, 2009, Mr. Godshall, Mr. McIntyre and other representatives of HeartWare’s senior management team met with Mr. Burbach and other representatives of Thoratec’s senior management team at Latham’s offices in San Francisco, California to conduct due diligence on Thoratec, and Mr. Godshall, Mr. McIntyre and other representatives of HeartWare’s senior management team and Mr. Burbach and other representatives of Thoratec’s senior management team met again by teleconference on January 15, 2009, together with representatives of J.P. Morgan, Shearman, Banc of America and Latham to continue those discussions. At those meetings, Mr. Burbach advised HeartWare that Thoratec’s wholly owned subsidiary, ITC, had received a 483 Notice of Observation report issued by the FDA in January 2009 as a result of an inspection of ITC’s facilities in New Jersey. HeartWare inquired about Thoratec’s plans to publicly disclose the 483 Notice of Observation report, and HeartWare noted that it would not proceed with the due diligence process until HeartWare had additional information regarding the 483 Notice of Observation Report, its implications and nature of Thoratec’s plans regarding disclosure of the report.

On January 18, 2009, the HeartWare board of directors met by teleconference to discuss the status of the transaction, including the results of HeartWare’s due diligence investigation to date. Later that evening, at the direction of the HeartWare board of directors, HeartWare informed Thoratec that it was terminating negotiations until Thoratec presented a timeline for public disclosure of ITC’s receipt of the 483 Notice of Observation report, or alternatively agreed to a transaction structure that did not include a fixed rate of exchange with respect to shares of Thoratec common stock offered as merger consideration, and HeartWare sent a notice to Thoratec requesting the return of confidential information that had been delivered to Thoratec in connection with the proposed transaction.
 
On January 20, 2009, representatives of HeartWare received additional information from Thoratec regarding the 483 Notice of Observation report, including Thoratec’s plans to publicly disclose ITC’s receipt of the 483 Notice of Observation report on February 5, 2009, in connection with its release of its fourth quarter 2008 earnings.

At that meeting, HeartWare executed a letter of intent with Thoratec that granted Thoratec exclusivity with respect to negotiating a change of control transaction with HeartWare from January 27, 2009 to the first to occur of (i) February 16, 2009 and (ii) the execution of definitive agreements with respect to the proposed transaction.
 
Later on January 27, 2009, Latham sent a draft of a proposed merger agreement and a proposed support agreement to HeartWare and Shearman. On January 29, 2009, Latham sent drafts of a proposed loan agreement, investor’s rights agreement and escrow agreement to HeartWare and Shearman.

Each of HeartWare’s and Thoratec’s senior management teams met regularly with their respective advisors to receive an update on the status of the negotiations, review issues and concerns that arose during negotiations and provide direction and instructions to their advisors. During this period, members of HeartWare’s senior management team regularly updated members of the HeartWare board of directors regarding the status of the discussions and the proposed resolution of the material open issues under the draft agreements.

On February 10, 2009, the Thoratec board of directors met with Mr. Burbach and other members of Thoratec’s senior management team and representatives of Banc of America and Latham.

The Thoratec board of directors and their advisors discussed the terms of the proposed acquisition of HeartWare and the terms of the merger agreement, the loan agreement and related documents.
 
On February 11, 2009, the HeartWare board of directors met by teleconference.

Extended discussion followed among the directors and their advisors, with numerous questions addressed by the HeartWare board of directors to HeartWare’s advisors regarding the draft agreements, the terms of the proposed transaction and the process between signing the definitive agreements and closing, including the likely timing of that process. Following these discussions, the HeartWare board of directors agreed to continue to review the information that had been presented to it regarding the proposed transaction, and to reconvene by teleconference the following day for purposes of making a final determination regarding whether HeartWare should proceed with the proposed transaction.

directors approved the merger agreement, the loan agreement and the other transaction agreements and the transactions contemplated thereby.
 
Following the meetings of each of the HeartWare board of directors and the Thoratec board of directors on February 12, 2009, HeartWare, Thoratec, Merger Subsidiary and Merger Subsidiary Two executed the merger agreement and the other transaction agreements.
 
Early in the morning of February 13, 2009, HeartWare and Thoratec issued a joint press release announcing their execution of the merger agreement and Messrs. Burbach, Smith, Godshall and McIntyre held a joint conference call for investors of both companies to discuss the merger.
 
HeartWare’s Reasons for the Merger and Recommendation of the HeartWare Board of Directors
 
In reaching its decision to approve the merger agreement and declare its advisability and to recommend that HeartWare stockholders vote in favor of the adoption of the merger agreement, the HeartWare board of directors consulted with HeartWare’s senior management team, as well as its outside legal and financial advisors, and considered a number of factors, including the following:
 
  •  Value of Merger Consideration.  The HeartWare board of directors considered the value of the per share merger consideration to be received by HeartWare stockholders in the merger. The HeartWare board of directors noted that HeartWare stockholders will receive $14.30 in cash and 0.6054 of a share of Thoratec common stock for each share of HeartWare common stock outstanding, which, based upon a volume weighted average closing price of Thoratec common stock for the four (4) days preceding the signing of the merger agreement of $26.25 per share, reflected a price of $30.19 per share of HeartWare common stock or $0.86 for each HeartWare CDI (based upon the then current US/AUS exchange rate of 1.5265), representing a significant premium to the current and historical trading prices for shares of HeartWare common stock and for HeartWare CDIs. The HeartWare board of directors also considered the current and historical trading prices of shares of Thoratec common stock as of the date of the meeting at which the HeartWare board of directors approved the merger, and noted that the current trading price of shares of Thoratec common stock was approximately 21.1% below the fifty-two (52) week high for these shares.
 
  •  The HeartWare board of directors also considered the fact that if the volume weighted average of the per share closing prices of Thoratec common stock on The NASDAQ Stock Market for the twenty (20) consecutive trading days ending on the fifth (5th) trading day prior to the closing date is less than $18.38 (70% of the $26.25 stock price used to calculate the merger consideration), then HeartWare will have an option to terminate the merger agreement unless Thoratec increases the number of shares of Thoratec common stock payable in the merger such that the value of the stock portion of the merger consideration as of the fifth (5th) business day prior to closing is equal to 70% of the value of the aggregate Thoratec stock consideration payable in the merger at the signing of the merger agreement (which was calculated using the $26.25 price per share of Thoratec common stock used to determine the stock portion of the merger consideration).
 
  •  The HeartWare board of directors further considered that if that same volume weighted average price as mentioned above exceeds $34.13 (130% of the $26.25 stock price used to calculate the merger consideration), then Thoratec may reduce the number of shares of Thoratec common stock payable in the merger such that the value of the stock portion of the merger consideration as of the fifth (5th) business day prior to closing is equal to 130% of the value of the aggregate Thoratec stock consideration payable in the merger at the signing of the merger agreement (which was calculated using the $26.25 price per share of Thoratec common stock used to determine the stock portion of the merger consideration).
 
  •  Form of the Merger Consideration.  The HeartWare board of directors considered that part of the merger consideration includes shares of Thoratec common stock and, therefore, in addition to the possibility that, for U.S. federal income tax purposes, the amount of gain, if any, recognized by U.S. holders of HeartWare common stock may be limited to the cash portion of the merger consideration received (as discussed below) and that, for Australian tax purposes, the stock portion of the merger consideration may be tax free to HeartWare stockholders (as discussed below), HeartWare stockholders will retain an equity interest in the combined enterprise with the related opportunity to share in its future growth.

  •  Strategic Advantages.  In light of the significant stock component of the merger consideration, the HeartWare board of directors also assessed the complementary strengths of each of the companies and the compatibility of the corporate structures. The HeartWare board of directors also reviewed information with respect to the prospects of the combined company, including the potential for the combined company, by using the existing strengths and relationships of each of Thoratec and HeartWare, to offer a broader range of treatments and to develop more effective and less invasive treatment options more quickly than if the companies were to remain separate entities. In addition, the board of directors also considered that the combined company would be more financially stable than HeartWare would be if it remained independent.
 
  •  Terms of the Merger Agreement.  The HeartWare board of directors, with the assistance of its legal advisors, reviewed the terms of the merger agreement, including:
 
  •  The ability of the HeartWare board of directors to respond to and engage in discussions or negotiations regarding unsolicited third-party acquisition proposals under certain circumstances and, ultimately, to terminate the merger agreement in order to accept a superior proposal;
 
  •  The fact that the HeartWare board of directors has the right to change its recommendation to the HeartWare stockholders that they vote in favor of the adoption of the merger agreement if the HeartWare board of directors determines in its good faith judgment prior to the HeartWare special meeting of stockholders and after consultation with its outside legal counsel and financial advisors, that the failure to change its recommendation would reasonably be expected to be inconsistent with its fiduciary duties to HeartWare stockholders under applicable law; and
 
  •  HeartWare’s right to terminate the merger agreement under certain circumstances, including if the volume weighted average closing price of shares of Thoratec common stock is less than $18.38 over the twenty (20) business day period ending five (5) business days prior to the closing of the merger.
 
  •  The Loan Agreement.  The HeartWare board of directors considered that Thoratec had agreed to provide a convertible loan facility of up to $28.0 million to fund ongoing operations, which will allow HeartWare to proceed with its product development and commercialization efforts without the need to raise additional financing, which the board viewed as particularly advantageous in light of the current state of the financing markets.
 
  •  HeartWare’s Business Conditions and Prospects.  The HeartWare board of directors considered information with respect to HeartWare’s financial condition, results of operations, business, competitive position and business prospects and risks, on both an historical and prospective basis, as well as current industry, economic and market conditions and trends. The HeartWare board of directors also took into account risks associated with HeartWare’s clinical trial program, its ability to obtain regulatory approval needed to commercialize its products and generate revenues and its ability to obtain the financing that would be necessary to allow it to continue its development program on terms that would not be overly dilutive to its current stockholders.
 
  •  Thoratec’s Business Condition and Prospects.  The HeartWare board of directors considered information with respect to Thoratec’s financial condition, results of operations, business, competitive position and business prospects and risks, on both an historical and prospective basis, as well as current industry, economic and market conditions and trends. In considering Thoratec’s condition and prospects, the HeartWare board of directors reviewed information regarding Thoratec’s historical performance and received reports from HeartWare’s senior management team regarding its due diligence review of Thoratec’s business and legal affairs and Thoratec’s management. The HeartWare board also took into account the expected effect of the merger on Thoratec’s EPS and EBITDA.
 
  •  Regulatory Matters.  The HeartWare board of directors considered the regulatory clearances that would be required as a condition to the merger and the prospects and anticipated timing of obtaining those clearances.
 
  •  Tax Treatment.  The HeartWare board of directors noted the expected tax treatment of the merger consideration to be received by HeartWare stockholders, including the fact that, subject to certain tax-related conditions being satisfied and the second merger occurring, the amount of gain, if any, recognized by


56


Table of Contents

  U.S. holders of HeartWare common stock for U.S. federal income tax purposes may be limited to the cash portion of the merger consideration received, and that, subject to a favorable tax ruling or other relief from Australian tax authorities, Australian holders of HeartWare common stock will not be required to recognize any gain on the stock portion of the merger consideration for Australian tax purposes.
 
  •  Potential Negative Considerations.  The HeartWare board of directors considered a number of potentially negative factors, as well as related mitigating factors in its deliberations concerning the merger agreement and the merger, including:
 
  •  The possibility that the merger might not be completed as a result of the failure to receive the required regulatory clearances or satisfy other closing conditions, including securing the required approval from HeartWare stockholders, which could result in a significant distraction to HeartWare employees and increased expenses from an unsuccessful attempt to complete the merger. In that regard, the board of directors considered the support agreements to be entered into by its directors and certain stockholders, on the one hand, and Thoratec, on the other hand, both in the context of making it more likely that stockholder approval for the merger would be obtained, and that the execution of these support agreements should not deter a superior proposal as they would terminate upon termination of the merger agreement in favor of a superior proposal.
 
  •  The risk that adverse changes to the business, assets, liabilities, condition (financial or otherwise) or operating results of HeartWare could result in a failure to complete the merger.
 
  •  The possibility that the value of the per share merger consideration could decrease prior to the closing of the merger if the trading price of Thoratec decreases below $26.25 per share (but remains higher than $18.38 per share) and the inability of HeartWare stockholders to participate in any pre-merger increases in the trading price of Thoratec common shares above $34.13 per share.
 
  •  The potential difficulties of integrating the businesses of HeartWare and Thoratec and the risk that all or some portion of the potential benefits of the merger might not be realized.
 
  •  The fact that, under the terms of the merger agreement, prior to the completion of the merger or termination of the merger agreement, HeartWare is required to conduct its business only in the ordinary course and is subject to specified restrictions on its ability to conduct its business, including in respect of entering into or terminating material contracts, commencing or settling litigation or increasing the compensation of its employees.
 
  •  HeartWare’s inability to solicit competing acquisition proposals and the possibility that the $11.3 million termination fee payable by HeartWare upon termination of the merger agreement could discourage other potential acquirers from making a competing offer to purchase HeartWare.
 
  •  The fact that in the event that the merger agreement is terminated due to a superior proposal, Thoratec may convert the outstanding principal amount of the loans to HeartWare under the loan agreement, as well as amounts then held in escrow pursuant to the loan agreement, into shares of HeartWare common stock based on a conversion rate equal to $21.5355 per share of HeartWare common stock, which could discourage other potential bidders from making a bid.
 
In the judgment of the HeartWare board of directors, however, these potential risks were more than offset by the potential benefits of the merger discussed above.
 
  •  Opinion of Financial Advisor.  The HeartWare board of directors also considered the oral opinion rendered by J.P. Morgan on February 12, 2009, which opinion was subsequently confirmed in writing, to the effect that, as of the date of the opinion and based on and subject to the factors, procedures, assumptions, qualifications and limitations set forth in the opinion, the merger consideration was fair, from a financial point of view, to HeartWare stockholders, and the analyses, methodologies and conclusions underlying such determinations, as described under “The Merger — Opinion of HeartWare’s Financial Advisor”, beginning on page 60 of this proxy statement/prospectus. A copy of J.P. Morgan’s written opinion is attached as Annex F to this proxy statement/prospectus.

  •  Additional Considerations.  In the course of its deliberations on the merger, the HeartWare board of directors consulted with members of HeartWare’s management and HeartWare’s legal, financial, accounting and tax advisors on various legal, business and financial matters. Additional factors considered by the HeartWare board of directors in determining whether to approve the merger agreement and declare its advisability and recommend that HeartWare stockholders vote to adopt the merger agreement include:
 
  •  The fact that HeartWare stockholders will have an opportunity to vote on the merger on the terms provided in the merger agreement.
 
  •  The fact that for one (1) year following the merger, employees that remain in the employment of HeartWare will receive employee benefits that, in the aggregate, are substantially similar to those received by similarly situated employees of Thoratec.
 
  •  The fact that at closing, holders of options issued under HeartWare’s employee stock option plan and holders of certain HeartWare incentive options will become entitled to receive a cash payment equal to the difference between $30.19 (the value of the merger consideration at signing) and the exercise price of the options and that at closing each restricted stock unit will be converted into the right to receive a cash payment of $30.19.
 
The foregoing discussion of the information and factors considered by the HeartWare board of directors is not exhaustive, but includes the material factors that the HeartWare board of directors considered. In view of the wide variety of factors considered in connection with its evaluation of the merger and related transactions and the complexity of these matters, the HeartWare board of directors did not find it useful, and did not attempt, to quantify, rank or otherwise assign relative weights to these factors. In considering the factors described above, individual members of the HeartWare board of directors may have given different weight to different factors. The HeartWare board of directors conducted an overall analysis of the factors described above, including discussions with, and questioning of, the management of HeartWare and HeartWare’s legal and financial advisors, and reached the consensus that the merger was advisable and in the best interests of HeartWare and HeartWare stockholders.
 
In considering the recommendation of the HeartWare board of directors to adopt the merger agreement, HeartWare stockholders should be aware that the executive officers and directors of HeartWare have certain interests in the merger that may be different from, or in addition to, the interests of HeartWare generally. The HeartWare board of directors was aware of these interests and considered them when adopting the merger agreement and recommending that HeartWare stockholders vote to adopt the merger agreement. See “The Merger — Interests of HeartWare Directors and Executive Officers in the Mergers” beginning on page 65.
 
Thoratec’s Reasons for the Merger
 
The Thoratec board of directors approved the merger agreement and the transactions contemplated by the merger agreement.
 
In reaching its decision to approve the merger agreement, the Thoratec board of directors consulted with senior members of Thoratec’s management team and with its financial, legal and accounting advisors regarding the strategic and operational aspects of combining Thoratec and HeartWare and the results of the due diligence efforts undertaken by management and Thoratec’s financial, legal and accounting advisors. In addition, the Thoratec board of directors held discussions with representatives of Banc of America, Thoratec’s financial advisor, and Thoratec’s other advisors regarding the past and current business operations, financial condition and future prospects of HeartWare. In reaching its decision to approve the merger agreement, the Thoratec board of directors considered a variety of factors, including the following:
 
  •  Strengthened Business and Operating Efficiencies.
 
  •  The complementary nature of the technology and products of HeartWare, including HeartWare’s current portfolio of miniaturized implantable heart pumps that have been approved for sale, are undergoing clinical trials or are under development, which would increase Thoratec’s portfolio of mechanical circulatory support devices and accelerate Thoratec’s development of enhanced technologies for heart failure patients.

  •  The expectation that, after the consummation of the merger, the greater scale and scope of the combined company’s operations could create added resources to fund ongoing, focused research and development programs, future technology innovations and clinical studies, and the combined company would be better positioned to grow through external initiatives, if and when such opportunities should arise.
 
  •  The expectation that the merger would result in operating synergies for the combined company over the long-term.
 
  •  Positioned for Long-Term Growth.
 
  •  The potential to accelerate Thoratec’s future revenue and earnings growth.
 
  •  The expectation that the merger would expand the acceptance and availability of mechanical circulatory support devices, including Thoratec’s and HeartWare’s products.
 
  •  The expectation that, after the consummation of the merger, the experience, resources and breadth of product offerings of the combined company would allow the combined company to respond more quickly and effectively to technological change and market demands.
 
  •  Merger Consideration.  The market price of Thoratec common stock payable to HeartWare stockholders in the merger is subject to specified maximum and minimum values, such that if the market price exceeds the maximum value, the stock portion of the merger consideration payable to HeartWare stockholders may be reduced by Thoratec and if the market price falls below the minimum value and HeartWare elects to terminate the merger agreement, Thoratec may elect to increase the number of shares of Thoratec stock payable to HeartWare stockholders and consummate the merger. See “The Merger Agreement — Merger Consideration” beginning on page 83 of this proxy statement/prospectus.
 
  •  Terms of the Merger Agreement.  The Thoratec board of directors, with the assistance of its legal advisors, reviewed the terms of the merger agreement, including the provisions in the merger agreement that prohibit HeartWare from soliciting other acquisition proposals and the circumstances under which a termination fee is payable by HeartWare to Thoratec under the merger agreement and the nature of the negotiating process that resulted in the termination fee provision.
 
  •  Support Agreements.  The agreement by all but one of HeartWare’s directors, certain executive officers and Apple Tree Partners, HeartWare’s largest stockholder, who collectively beneficially own in the form of HeartWare CDIs (and in the case of Mr. Godshall, in the form of shares of HeartWare common stock), as of the HeartWare record date, approximately 31.6% of the total outstanding shares of HeartWare common stock, to vote or give directions to vote their respective shares of HeartWare common stock for the adoption of the merger agreement with Thoratec, subject to the terms and conditions of the support agreements. See “The Support Agreements” beginning on page 109 of this proxy statement/prospectus.
 
Potential Negative Considerations.  The Thoratec board of directors considered a number of potentially negative factors, as well as related mitigating factors, in its deliberations concerning the merger agreement, including:
 
  •  The risk of obtaining required regulatory approvals relating to the merger and the possibility that the merger might not be completed or might be unduly delayed, even if HeartWare’s stockholders approve the merger.
 
  •  The potential adverse consequences to Thoratec if the merger is not completed or is significantly delayed.
 
  •  That the merger will be dilutive to Thoratec’s earnings on both a GAAP and non-GAAP basis into 2011.
 
  •  The expectation that Thoratec will record non-recurring charges associated with the acquisition of HeartWare of approximately $15.0 million to $20.0 million in 2009.
 
  •  The risk that anticipated cost savings, operational synergies and other benefits sought in the merger might not be fully realized.
 
  •  The time, effort and costs incurred in connection with the negotiation and implementation of the merger and involved in integrating the management teams, strategies, cultures and organizations of the two companies


59

  following the closing, including the risk of diverting management’s attention from the operation of Thoratec’s business and from other strategic priorities.
 
  •  The fact that the outcome of ongoing clinical trails related to HeartWare’s products may not be favorable and that regulatory approvals necessary to market and sell those products may not be received in a timely manner or at all.
 
  •  The risk that Thoratec may not be able to retain key employees of HeartWare following the closing.
 
  •  The fact that certain preferred stockholders have a minority interest in HeartWare, Inc. and that HeartWare, Inc. is not a wholly-owned subsidiary of HeartWare.
 
  •  The other risks of the type and nature described under “Risk Factors” beginning on page 25 of this proxy statement/prospectus.
 
After consideration of these factors, the Thoratec board of directors determined that these risks could be mitigated or managed by Thoratec, HeartWare or by the combined company following the merger, were reasonably acceptable under the circumstances or, in light of the anticipated benefits, the risks were unlikely to have a materially adverse impact on the merger or on the combined company following the merger, and that, overall, these risks were significantly outweighed by the potential benefits of the merger.
 
The Thoratec board of directors considered all of the foregoing factors as a whole and determined to approve the merger agreement.
 
The foregoing discussion of the information and factors considered by the Thoratec board of directors is not exhaustive, but Thoratec believes it includes all the material factors considered by the Thoratec board of directors. In view of the wide variety of factors considered by the Thoratec board of directors in connection with its evaluation of the mergers and the complexity of these matters, the Thoratec board of directors did not consider it practical, and did not attempt, to quantify, rank or otherwise assign relative weights to the specific factors it considered in reaching its decision. Rather, the Thoratec board of directors made its decision based on the totality of information presented to, and the investigation conducted by, it. In considering the factors discussed above, individual directors may have given different weights to different factors.
 
Opinion of HeartWare’s Financial Advisor
 
Pursuant to an engagement letter dated December 2, 2008, HeartWare retained J.P. Morgan to act as its financial advisor in connection with the transactions contemplated by the merger agreement.
 
At the meeting of the HeartWare board of directors on February 12, 2009, J.P. Morgan rendered its oral opinion, subsequently confirmed in writing, to the HeartWare board of directors that, as of such date and based upon and subject to the factors, procedures, assumptions, qualifications and limitations set forth in its opinion, the merger consideration to be paid to the holders of shares of HeartWare common stock in the merger was fair, from a financial point of view, to such holders.
 
The full text of the written opinion of J.P. Morgan dated February 12, 2009, which sets forth, among other things, the assumptions made, procedures followed, matters considered, and qualifications and limitations on the review undertaken in connection with its opinion, is included as Annex F to this proxy statement/prospectus and is incorporated herein by reference. The summary of J.P. Morgan’s opinion below is qualified in its entirety by reference to the full text of the opinion, and HeartWare stockholders are urged to read the opinion carefully and in its entirety. J.P. Morgan provided its opinion for the information of the HeartWare board of directors in connection with and for the purposes of the evaluation of the transactions contemplated by the merger agreement. J.P. Morgan’s written opinion addresses only the consideration to be paid to the holders of shares of HeartWare common stock in the merger, and does not address any other matter. J.P. Morgan’s opinion does not constitute a recommendation to any stockholder of HeartWare as to how such stockholder should vote with respect to any matter. The consideration to be paid to the holders of shares of HeartWare common stock in the merger was determined in negotiations between HeartWare and Thoratec, and the decision to approve and recommend the merger was made independently by the HeartWare board of directors.

In arriving at its opinion, J.P. Morgan, among other things:
 
  •  reviewed the merger agreement;
 
  •  reviewed certain publicly available business and financial information concerning HeartWare and Thoratec and the industries in which they operate;
 
  •  compared the proposed financial terms of the merger with the publicly available financial terms of certain transactions involving companies J.P. Morgan deemed relevant and the consideration received for such companies;
 
  •  compared the financial and operating performance of HeartWare and Thoratec with publicly available information concerning certain other companies J.P. Morgan deemed relevant and reviewed the current and historical market prices of the shares of HeartWare common stock and Thoratec common stock and certain publicly traded securities of such other companies;
 
  •  reviewed certain internal financial analyses and forecasts prepared by or at the direction of the managements of HeartWare and Thoratec relating to their respective businesses, as well as discussed the estimated amount and timing of the cost savings and related expenses and synergies expected by the managements of HeartWare and Thoratec to result from the merger; and
 
  •  performed such other financial studies and analyses and considered such other information as J.P. Morgan deemed appropriate for the purposes of its opinion.
 
In addition, J.P. Morgan held discussions with certain members of the management of HeartWare and Thoratec with respect to certain aspects of the merger and the past and current business operations of HeartWare and Thoratec, the financial condition and future prospects and operations of HeartWare and Thoratec, the effects of the merger on the financial condition and future prospects of HeartWare and Thoratec and certain other matters J.P. Morgan believed necessary or appropriate to its inquiry.
 
In giving its opinion, J.P. Morgan relied upon and assumed the accuracy and completeness of all information that was publicly available or was furnished to or discussed with J.P. Morgan by HeartWare and Thoratec or otherwise reviewed by or for J.P. Morgan, and J.P. Morgan has not independently verified (nor has J.P. Morgan assumed responsibility or liability for independently verifying) any such information or its accuracy or completeness. J.P. Morgan has not conducted or been provided with any valuation or appraisal of any assets or liabilities, nor has J.P. Morgan evaluated the solvency of HeartWare or Thoratec under any state or federal laws relating to bankruptcy, insolvency or similar matters. In relying on financial analyses and forecasts provided to J.P. Morgan or derived therefrom, including the synergies referred to above, J.P. Morgan has assumed that they have been reasonably prepared based on assumptions reflecting the best currently available estimates and judgments by management as to the expected future results of operations and financial condition of HeartWare and Thoratec to which such analyses or forecasts relate. J.P. Morgan expresses no view as to such analyses or forecasts (including the synergies referred to above) or the assumptions on which they were based. J.P. Morgan has also assumed that the merger and the other transactions contemplated by the merger agreement will have the tax consequences described in discussions with, and materials furnished to J.P. Morgan by, representatives of HeartWare, and will be consummated as described in the merger agreement. J.P. Morgan has also assumed that the representations and warranties made by HeartWare and Thoratec in the merger agreement and the related agreements are and will be true and correct in all respects material to J.P. Morgan’s analysis, and that there will not be any adjustment to the stock portion of merger consideration that is material to their analysis. J.P. Morgan is not a legal, regulatory or tax expert and has relied in all legal, regulatory and tax matters on the assessments made by advisors to HeartWare with respect to such issues. J.P. Morgan has further assumed that all material governmental, regulatory or other consents and approvals necessary for the consummation of the merger will be obtained without any adverse effect on HeartWare or Thoratec or on the contemplated benefits of the merger.
 
The forecasts furnished to J.P. Morgan by HeartWare and Thoratec were prepared by the managements of HeartWare and Thoratec. Neither HeartWare nor Thoratec publicly discloses internal management forecasts of the type provided to J.P. Morgan in connection with J.P. Morgan’s analysis of the merger, and such forecasts were not prepared with a view toward public disclosure. These forecasts were based on numerous variables and assumptions

that are inherently uncertain and may be beyond the control of management, including, without limitation, factors related to general economic and competitive conditions and prevailing interest rates. Accordingly, actual results could vary significantly from those set forth in such forecasts.
 
J.P. Morgan’s opinion is necessarily based on economic, market and other conditions as in effect on, and the information made available to J.P. Morgan as of, the date of its opinion. It should be understood that subsequent developments may affect J.P. Morgan’s opinion and that J.P. Morgan does not have any obligation to update, revise, or reaffirm its opinion. J.P. Morgan’s opinion is limited to the fairness, from a financial point of view, of the consideration to be paid to the holders of the shares of HeartWare common stock in the merger and J.P. Morgan expresses no opinion as to the fairness of the merger to, or any consideration paid in connection therewith to, the holders of any other class of securities, creditors or other constituencies of HeartWare or as to the underlying decision by HeartWare to engage in the merger. Furthermore, J.P. Morgan expresses no opinion with respect to the amount or nature of any compensation to any officers, directors, or employees of any party to the merger, or any class of such persons relative to the consideration to be paid to the holders of the shares of HeartWare common stock in the merger or with respect to the fairness of any such compensation. J.P. Morgan expresses no opinion as to the price at which HeartWare common stock or Thoratec common stock will trade at any future time, whether before or after the closing of the merger.
 
In accordance with customary investment banking practice, J.P. Morgan employed generally accepted valuation methods in reaching its opinion. The following is a summary of the material financial analyses utilized by J.P. Morgan in connection with providing its opinion. The financial analyses summarized below include information presented in tabular format. In order to fully understand J.P. Morgan’s financial analyses, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses. Considering the data described below without considering the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of J.P. Morgan’s financial analyses.
 
Financial Analyses — HeartWare
 
Selected public benchmarks analysis
 
Using publicly available information, J.P. Morgan compared selected financial data of HeartWare with similar data for selected publicly traded companies engaged in businesses which J.P. Morgan judged to be analogous to HeartWare’s business. These companies were selected, among other reasons, because they share similar business characteristics to HeartWare based on operational characteristics and financial metrics. However, none of the companies selected is identical or directly comparable to HeartWare. Accordingly, J.P. Morgan made judgments and assumptions concerning differences in financial and operating characteristics of the selected companies and other factors that could affect the public trading value of the selected companies.
 
For each selected company, J.P. Morgan calculated such company’s firm value divided by its estimated revenue, which we refer to as FV/Revenue, for fiscal year 2010. For purposes of this analysis, a company’s firm value is calculated as the fully diluted common equity value of such company as of February 11, 2009, plus the value of such company’s indebtedness and minority interests and preferred stock, minus such company’s cash, cash equivalents and marketable securities.
 
The following table represents the results of this analysis:
 
                 
Peer Group
  Mean   Median
 
FV/Revenue
    2.7x       3.0x  
 
Based on the results of this analysis and other factors that J.P. Morgan considered appropriate, J.P. Morgan applied a FV/Revenue of 2.0x to 3.5x to HeartWare’s estimated revenue for fiscal year 2010. This resulted in an implied equity value per share of HeartWare common stock of $9.75 to $15.00.
 
Selected precedent transactions analysis
 
Using publicly available information, J.P. Morgan examined the following selected transactions involving businesses which J.P. Morgan judged to be analogous to HeartWare’s business. These transactions were selected,

For each of the selected transactions, J.P. Morgan calculated and, to the extent information was publicly available, compared the transaction value divided by the target’s one-year forward revenue for the one-year period immediately following the announcement of the respective transaction, which we refer to as a Transaction Value/FTM Revenue Multiple.
 
The following table represents the results of this analysis:
 
         
    Transaction Value/FTM
    Revenue Multiple
 
High
    14.2 x
Low
    4.5 x
Median
    6.1 x
 
Based on the results of this analysis and other factors that J.P. Morgan considered appropriate, J.P. Morgan derived a Transaction Value/FTM Revenue Multiple of 5.0x to 8.0x to HeartWare’s estimated revenue for fiscal year 2009. This resulted in an implied equity value per share of common stock of HeartWare of $11.25 to $16.25.
 
Discounted cash flow analysis
 
J.P. Morgan conducted a discounted cash flow analysis for the purpose of determining the fully diluted equity value per share of HeartWare common stock. J.P. Morgan calculated the unlevered free cash flows that HeartWare is expected to generate during fiscal years 2009 through 2022 based upon the financial forecasts prepared by HeartWare’s management. J.P. Morgan also calculated a range of terminal firm values for HeartWare by applying, based upon J.P. Morgan’s judgment and experience, a perpetual growth rate ranging from 2.50% to 3.50% to HeartWare’s unlevered free cash flow during the final year of the fourteen (14)-year period ending 2022 and using a range of discount rates from 19.0% to 21.0%. This discount rate range was based upon an analysis of the weighted average cost of capital of HeartWare conducted by J.P. Morgan. The unlevered free cash flows and the range of terminal firm values were then discounted to present values using the same range of discount rates from 19.0% to 21.0%. The present value of the unlevered free cash flows and the range of terminal firm values were then adjusted for HeartWare’s excess cash and total debt as of December 31, 2008. Based on the foregoing, this analysis indicated an implied fully diluted equity value per share of HeartWare common stock of between $20.50 to $26.25, on a stand-alone basis (i.e., without synergies). J.P. Morgan also performed discounted cash flow analyses on upside and downside sensitivities to management’s forecasts, which analyses were not material in determining fairness.

Financial Analyses — Thoratec
 
Selected public benchmarks analysis
 
Using publicly available information, J.P. Morgan compared selected financial data of Thoratec with similar data for selected publicly traded companies engaged in businesses which J.P. Morgan judged to be analogous to Thoratec’s business. These companies were selected, among other reasons, because they share similar business characteristics to Thoratec based on operational characteristics and financial metrics. However, none of the companies selected is identical or directly comparable to Thoratec. Accordingly, J.P. Morgan made judgments and assumptions concerning differences in financial and operating characteristics of the selected companies and other factors that could affect the public trading value of the selected companies.
 
For each selected company, J.P. Morgan calculated such company’s firm value divided by its estimated revenue, which we refer to as FV/Revenue, for fiscal years 2009 and 2010. For purposes of this analysis, a company’s firm value is calculated as the fully diluted common equity value of such company as of February 11, 2009, plus the value of such company’s indebtedness and minority interests and preferred stock, minus such company’s cash, cash equivalents and marketable securities.
 
The following table represents the results of this analysis:
 
                                 
    Mean   Median
Peer Group
  2009   2010   2009   2010
 
FV/Revenue
    3.5 x     3.1 x     3.5 x     3.3x  
 
Based on the results of this analysis and other factors that J.P. Morgan considered appropriate, J.P. Morgan applied a FV/Revenue of 3.0x to 4.5x to Thoratec’s estimated revenue for fiscal year 2009 and a FV/Revenue of 2.0x to 4.0x to Thoratec’s estimated revenue for fiscal year 2010. This resulted in an implied equity value per share of Thoratec common stock of $19.50 to $29.75.
 
Discounted cash flow analysis
 
J.P. Morgan conducted a discounted cash flow analysis for the purpose of determining the fully diluted equity value per share of Thoratec common stock. J.P. Morgan calculated the unlevered free cash flows that Thoratec is expected to generate during fiscal years 2009 through 2018 based upon the financial forecasts prepared by HeartWare’s management. J.P. Morgan also calculated a range of terminal firm values for Thoratec by applying, based upon J.P. Morgan’s judgment and experience, a perpetual growth rate ranging from 2.50% to 3.50% to Thoratec’s unlevered free cash flow during the final year of the 10-year period ending 2018 and using a range of discount rates from 10.0% to 12.0%. This discount rate range was based upon an analysis of the weighted average cost of capital of Thoratec conducted by J.P. Morgan. The unlevered free cash flows and the range of terminal firm values were then discounted to present values using the same range of discount rates from 10.0% to 12.0%. The present value of the unlevered free cash flows and the range of terminal firm values were then adjusted for Thoratec’s excess cash and total debt as of December 31, 2008. Based on the foregoing, this analysis indicated an implied fully diluted equity value per share of Thoratec common stock of between $27.50 to $38.25, on a stand-alone basis (i.e., without synergies).
 
The foregoing summary of certain material financial analyses does not purport to be a complete description of the analyses or data presented by J.P. Morgan. The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. J.P. Morgan believes that the foregoing summary and its analyses must be considered as a whole and that selecting portions of the foregoing summary and these analyses, without considering all of its analyses as a whole, could create an incomplete view of the processes underlying the analyses and its opinion. In arriving at its opinion, J.P. Morgan did not attribute any particular weight to any analyses or factors considered by it and did not form an opinion as to whether any individual analysis or factor (positive or negative), considered in isolation, supported or failed to support its opinion. Rather, J.P. Morgan considered the results of all its analyses as a whole and made its determination as to fairness on the basis of its experience and professional judgment after considering the results of all of its analyses.
 
Analyses based on forecasts of future results are inherently uncertain, as they are subject to numerous factors or events beyond the control of the parties and their advisors. Accordingly, forecasts and analyses used or made by


64


Table of Contents

J.P. Morgan are not necessarily indicative of actual future results, which may be significantly more or less favorable than suggested by those analyses. Moreover, J.P. Morgan’s analyses are not and do not purport to be appraisals or otherwise reflective of the prices at which businesses actually could be bought or sold. None of the selected companies reviewed as described in the above summary is identical to HeartWare, and none of the selected transactions reviewed as described in the above summary was identical to the merger. However, the companies selected were chosen because they are publicly traded companies with operations and businesses that, for purposes of J.P. Morgan’s analysis, may be considered similar to those of HeartWare. The transactions selected were similarly chosen for their participants, size and other factors that, for purposes of J.P. Morgan’s analysis, may be considered similar to those of the merger. The analyses necessarily involve complex considerations and judgments concerning differences in financial and operational characteristics of the companies involved and other factors that could affect the companies compared to HeartWare and the transactions compared to the merger.
 
The opinion of J.P. Morgan was one of the many factors taken into consideration by the HeartWare board of directors in making its determination to approve the merger. The analyses of J.P. Morgan as summarized above should not be viewed as determinative of the opinion of the HeartWare board of directors with respect to the value of HeartWare or Thoratec, or of whether the HeartWare board of directors would have been willing to agree to different or other forms of consideration.
 
As part of its investment banking and financial advisory business, J.P. Morgan and its affiliates are continually engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, investments for passive and control purposes, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and valuations for estate, corporate and other purposes.
 
J.P. Morgan has acted as financial advisor to HeartWare with respect to the merger and will receive a fee from HeartWare for its services if the merger is consummated. In addition, HeartWare has agreed to indemnify J.P. Morgan for certain liabilities arising out of its engagement. During the two years preceding the date of J.P. Morgan’s opinion, neither J.P. Morgan nor its affiliates had any other significant commercial or investment banking relationships with HeartWare or Thoratec. In the ordinary course of J.P. Morgan’s businesses, J.P. Morgan and its affiliates may actively trade the debt and equity securities of HeartWare or Thoratec for its own account or for the accounts of customers and, accordingly, J.P. Morgan may at any time hold long or short positions in such securities.
 
Interests of HeartWare Directors and Executive Officers in the Mergers
 
In considering the recommendation of the HeartWare board of directors with respect to the merger, HeartWare stockholders should be aware that certain executive officers and non-employee directors of HeartWare have certain interests in the merger that may be different from, or in addition to, the interests of HeartWare stockholders generally. The HeartWare board of directors was aware of the interests described below and considered them, among other matters, when approving the merger agreement and recommending that the HeartWare stockholders vote to adopt the merger agreement. These interests are summarized below.
 
Equity Compensation Awards
 
The merger agreement provides that, at or immediately prior to the effective time, the terms of each then outstanding vested HeartWare incentive option and each then outstanding option to purchase shares of HeartWare common stock issued under the HeartWare employee stock option plan will be adjusted to provide that, at or immediately prior to the effective time of the merger, each vested HeartWare incentive option and each HeartWare employee stock option, whether or not exercisable or vested, that is outstanding immediately prior to the effective time will be cancelled and will convert into a right to receive a cash payment, without interest, equal to (i) the excess, if any, of $30.19 over the applicable exercise price per share of HeartWare common stock of such cancelled option multiplied by (ii) the number of shares of HeartWare common stock such holder would have purchased (assuming full vesting of each outstanding option to purchase shares of HeartWare common stock issued under the HeartWare employee stock option plan) had such holder exercised such cancelled option in full immediately prior to the effective time. Based upon the number of unvested HeartWare employee stock options outstanding as of the HeartWare record date, the unvested HeartWare employee stock options held by the HeartWare non-employee


65


Table of Contents

directors and executive officers relating to 203,445 shares of HeartWare common stock will be cancelled and will be converted into aggregate cash payments of $2.4 million.
 
The merger agreement also provides that, at the effective time of the merger, each then outstanding unvested HeartWare incentive option shall cease to represent the right to acquire shares of HeartWare common stock and will be converted into, and deemed to constitute, an option to acquire, on the same terms and conditions as were applicable under such HeartWare incentive option, a number of shares of Thoratec common stock equal to the product of (i) the number of shares of HeartWare common stock represented by such unvested HeartWare incentive option and (ii) 1.1499, rounded down, to the nearest whole share of Thoratec common stock, and such new option to acquire Thoratec common stock will have an exercise price per share (rounded up to the nearest cent) equal to (x) the per share exercise price specified in such HeartWare incentive option divided by (y) 1.1499. The 1.1499 exchange ratio for each outstanding unvested HeartWare incentive option is subject to the same volume weighted average price adjustments to the stock portion of the merger consideration described in the section entitled, “The Merger Agreement — Merger Consideration” beginning on page 83 of this proxy statement/prospectus. See “The Merger Agreement — Treatment of Options and Other Equity-Based Awards” beginning on page 87 of this proxy statement/prospectus. As of the HeartWare record date, there were no outstanding unvested HeartWare incentive options held by the HeartWare non-employee directors and executive officers.
 
Pursuant to the terms of the merger agreement, the exercise price for any HeartWare employee stock option or HeartWare incentive option that is measured in Australian dollars will be deemed to be converted to U.S. dollars at an exchange rate of 1.5265 Australian dollars for each U.S. dollar.
 
Further, the merger agreement provides that the terms of each HeartWare stock-based award, other than HeartWare incentive options and HeartWare employee stock options, will be adjusted as necessary to provide that at, or immediately prior to the effective time, each such HeartWare stock-based award, whether or not exercisable or vested, that is outstanding immediately prior to the effective time, will be cancelled and will convert into the right to receive a cash payment, without interest, equal to $30.19 multiplied by the number of shares of HeartWare common stock the holder of such HeartWare stock-based award would have received had such HeartWare stock-based award been fully earned, vested and exercisable and had been exercised or settled immediately prior to the effective time. See “The Merger Agreement — Treatment of Options and Other Equity-Based Awards” beginning on page 87 of this proxy statement/prospectus. Based upon the number of restricted stock units, or RSUs, as of the HeartWare record date, RSUs held by the HeartWare executive officers and non-employee directors relating to 82,138 shares will be cancelled and will be converted into aggregate cash payments of $2.5 million.

Executive Officer Employment Agreements, Retention Bonus Agreements, Thoratec Offer Letters and Separation Benefits Agreements
 
Executive Officer Employment Agreements.  Each of HeartWare’s executive officers is a party to an employment agreement that requires HeartWare to make certain payments and provide certain benefits if the executive’s employment is terminated by HeartWare without “cause” (as defined in the agreement) or is terminated by the executive officer for “good reason” (as defined in the agreement) within eighteen (18) months following a change in control of HeartWare.

Table of Contents

Mr. Godshall’s employment agreement provides for a lump-sum cash payment of two (2) times the aggregate of his base salary and the most recent annual bonus (employment agreements for Messrs. McIntyre and LaRose provide for a similar payment, however, their change in control benefits have been addressed in their separation benefits agreements with Thoratec, described below). With regard to Messrs. Schuermann, Yomtov, Paz, Hathaway and Ms. Farrell, their employment agreements provide for a lump-sum cash payment equal to one (1) year of the executive’s base salary. The employment agreements also provide for continued payment of the executive’s portion of elected Consolidated Omnibus Budget Reconciliation Act of 1985, which we refer to as COBRA, continuation coverage for a period of twelve (12) months (twenty-four (24) months for Mr. Godshall) or, if earlier, until the executive becomes entitled to participate in another employer’s health plan. Additionally, the employment agreements require the company to provide sixty (60) days’ (or ninety (90) days’ for Mr. Godshall), prior written notice for a termination of employment, other than for cause, or to provide additional severance to the extent such notice is not given. Upon a termination following a change in control, Messrs. Godshall, Schuermann, Yomtov, Paz, Hathaway and Ms. Farrell are entitled to severance payments of $920,000, $243,000, $189,000, $210,600, $250,000, and $195,000, respectively. Upon the closing of the merger, the employment agreements for Messrs. McIntyre and LaRose will terminate and their continuing employment will be governed by the offer letters and separation benefits agreements described below.
 
Severance payments and benefits are conditioned on the executive’s execution of a release of claims against HeartWare, its affiliates and personnel. In addition, pursuant to their employment agreements, the executives may be subject to an ongoing confidentiality obligation, post-employment non-competition, non-solicitation and non-disparagement covenants and they must continue to comply with the terms of their Proprietary Information, Confidentiality and Invention Assignment Agreement. Additionally, pursuant to the employment agreements, if the HeartWare board of directors determines that an executive has engaged in any activity that contravenes any restrictive covenant set forth in the agreement, the executive will forfeit any severance payable, in addition to repaying the previously paid severance pay, within thirty (30) days after receipt of the HeartWare board of directors’ determination notice.
 
Retention Bonus Agreements.  Messrs. Godshall, McIntyre and LaRose have each entered into a retention bonus agreement with HeartWare. Mr. Godshall’s retention bonus agreement provides for the payment of $3.3 million within thirty (30) days following the closing of the merger, subject to his continued employment through the closing of the merger and his entry into a consulting agreement with Thoratec that has a term of at least three (3) months. In the event that, prior to the close of the merger, Mr. Godshall is terminated without “cause” (as defined by Mr. Godshall’s employment agreement) or resigns for “good reason” (as defined by Mr. Godshall’s employment agreement), the retention bonus will vest in full and be paid on the later of (i) the closing of the merger and (ii) within sixty (60) days following such termination, subject to Mr. Godshall entering into a general release of claims.
 
Mr. McIntyre’s retention bonus agreement provides for payments totaling $2.1 million that vest and are paid in two (2) equal installments (the second installment of which is subject to accelerated vesting that may occur pursuant to termination without cause, resignation under certain circumstances, death or disability). Mr. McIntyre receives his first installment if he remains employed through the closing of the merger and the second installment on the first anniversary of the closing of the merger, on the condition that he remain employed through that date. In the event that Mr. McIntyre is terminated without “cause” (as defined in Mr. McIntyre’s separation benefits agreement), resigns for “good reason” (as defined in Mr. McIntyre’s separation benefits agreement), or resigns for any reason after six (6) consecutive months of service with Thoratec following the closing of the merger (and provides three (3) months notice prior to the resignation date), any unvested retention bonus will vest and be paid within sixty (60) days following such termination, subject to Mr. McIntyre entering into a general release of claims. Pursuant to the retention bonus agreement, Mr. McIntyre waived resignation for “good reason” as a result of any changes of employment due to the mergers.
 
Mr. LaRose’s retention bonus agreement provides for payments totaling $1.7 million that vest and are paid in two equal installments (subject to accelerated vesting that may occur pursuant to termination without cause, resignation without good reason, death or disability). Mr. LaRose receives his first installment if he remains employed through the closing of the merger and the second installment on the first anniversary of the closing of the merger, on the condition that he remain employed through that date. In the event that Mr. LaRose is terminated


68


Table of Contents

without “cause” (as defined in Mr. LaRose’s separation benefits agreement) or resigns for “good reason” (as defined in Mr. LaRose’s separation benefits agreement), any unvested retention bonus will vest and be paid within sixty (60) days following such termination, subject to Mr. LaRose entering into a general release of claims. Pursuant to the retention bonus agreement, Mr. LaRose waived resignation for “good reason” as a result of any changes of employment due to the mergers.
 
Each executive with a retention bonus agreement will be solely responsible for all taxes with respect to any payment received, including, without limitation, any excise tax imposed by Section 4999 of the Internal Revenue Code of 1986, as amended, which we refer to as the Internal Revenue Code; provided, however, that if the payments and benefits received constitute an “excess parachute payment” (as defined under Section 280G of the Internal Revenue Code), such payments and benefits will be reduced to the extent necessary to prevent any portion from becoming nondeductible by HeartWare or subject to excise tax imposed under Section 4999 of the Internal Revenue Code, but only if the net after-tax benefit received by the executive by reason of the reduction will exceed the net after-tax benefit that he would receive if no such reduction was made.
 
Subject to certain conditions, HeartWare will also be permitted to award additional cash retention bonuses to other HeartWare employees, payable on or following the effective time of the merger. The maximum aggregate amount payable (inclusive of any and all payments, reimbursements and tax gross-ups) pursuant to such additional cash retention bonuses and the retention bonus agreements discussed above will be $8.0 million. As part of the additional cash retention bonuses, retention bonus letters for Messrs. Schuermann, Paz, Yomtov, Hathaway, and Ms. Farrell provide for payment of $150,000, $150,000, $100,000, $80,000, and $100,000, respectively, ninety (90) days following the closing of the merger, subject to continued employment through the entirety of this period. In the event that, prior to the end of this period, the executive is terminated without “cause” (as defined by the executive’s employment agreement) or in the event of death or disability of the executive, the retention bonus, whether vested or unvested, will be paid in full, provided that the executive enters into a general release of claims. See, “The Merger Agreement — Obligations with Respect to Continuing Employees and Benefit Matters” beginning on page 97 of this proxy statement/prospectus.
 
Thoratec Offer Letters.  Messrs. McIntyre and LaRose have accepted employment with Thoratec that become effective on the closing of the merger. Mr. McIntyre has accepted a position as Vice President of Business Operations in the Cardiovascular Division of Thoratec. Mr. McIntyre’s offer letter provides for (i) an annual base salary of $260,000, (ii) options to purchase 25,000 shares of Thoratec common stock that vest ratably over four years, (iii) 20,000 RSUs that convert one-for-one into shares of common stock of Thoratec that vest ratably over four years, (iv) a bonus opportunity equal to 60% of his base salary, payable based on the achievement of his 2009 individual and corporate objectives (prorated based on hire date) and (v) a monthly housing allowing of $10,000.
 
Mr. LaRose has accepted a position as Vice President of Advanced Development in Thoratec’s Research and Development group. Mr. LaRose’s offer letter provides for (i) an annual base salary of $260,000, (ii) options to purchase 20,000 shares of Thoratec common stock that vest ratably over four years, (iii) 15,000 RSUs that convert one-for-one into shares of common stock of Thoratec that vest ratably over four (4) years, and (iv) a bonus opportunity equal to 50% of his base salary, payable based on the achievement of his 2009 individual and corporate objectives (prorated based on hire date).
 
Separation Benefits Agreements.  Messrs. McIntyre and LaRose have entered into substantially similar separation benefits agreements with Thoratec that become effective on the closing of the merger and supersede the employment agreements of Messrs. McIntyre and LaRose with HeartWare. These separation benefits agreements require Thoratec to make certain payments and provide certain benefits if the executive officer’s employment is involuntarily terminated by Thoratec without “cause” (as defined in the agreement) or by the executive for “good reason” (as defined in the agreement).
 
The separation benefits agreements of Messrs. McIntyre and LaRose provide for the payment of two (2) times the then-current annual base salary if employment is involuntarily terminated without “cause” (as defined in the agreement) within twelve (12) months after the close of the merger. If the applicable executive’s employment is involuntarily terminated more than twelve (12) months following the close of the merger, the executive will be paid severance equal to one year of his then-current base salary. The separation benefits agreements also provide for continued payment or reimbursement of the executive’s portion of elected COBRA continuation coverage for a


69


Table of Contents

period of twelve (12) months following a termination without “cause” (as defined in the agreement) or resignation for “good reason” (as defined in the agreement) or, if earlier, until the applicable executive becomes entitled to participate in another employer’s health plan. These agreements also provide Messrs. McIntyre and LaRose certain change in control protections upon a change in control of Thoratec.
 
Additionally, Mr. McIntyre’s agreement provides that if he is terminated for any reason, other than for “cause”, after nine months of continuous employment with Thoratec following the close of the merger, Thoratec will reimburse certain of Mr. McIntyre and his dependents’ relocation costs and provide a lump-sum payment equivalent to one month of his then-current base salary.
 
In the event that any payment or benefit payable is subject to the excise tax imposed by Section 4999 of the Internal Revenue Code, the applicable executive will be paid an additional payment, which we refer to as a Gross-Up Payment, in an amount that after the payment by the executive of all taxes, including, without limitation, any income taxes and excise tax imposed upon the Gross-Up Payment, the executive will retain the full remaining amount of the payment without being reduced by the excise tax imposed upon the payment. Under the terms of the separation benefits agreement, the executive will not be paid a Gross-Up Payment with respect to any payments or benefits deemed to be a “parachute payment” within the meaning of Section 280G(b)(2) of the Internal Revenue Code in connection with the merger.
 
Each separation benefits agreement requires that in order to receive any payments the executive must execute and not revoke an effective release of claims, in a form acceptable to Thoratec, and remain in compliance with all applicable restrictive covenants set forth in the separation benefits agreement, the employee confidential information and inventions agreement and the non-competition agreement. The proprietary information, confidentiality and inventions assignment agreement requires an employee to, among other things, assign all rights, including all intellectual property rights, to HeartWare, Inc. without further compensation and prevents the executive from revealing any of HeartWare’s trade secrets or confidential information concerning the organization, business or finances, for a period of five (5) years after cessation of employment.
 
Ownership of Thoratec Following the Merger
 
Based on the number of outstanding shares of HeartWare common stock (including shares represented by HeartWare CDIs) on the HeartWare record date, the number of outstanding shares of Thoratec common stock on the HeartWare record date and assuming an exchange ratio of 0.6054, we anticipate that the holders of outstanding shares of HeartWare common stock (excluding holders of options and other awards) will own approximately 9.6% of the outstanding shares of Thoratec common stock following the merger.
 
Effective Time of the Mergers
 
The merger will become effective upon the filing of a certificate of merger with the Secretary of State of the State of Delaware or at such other time as is agreed upon by HeartWare and Thoratec and specified as the effective time in the certificate of merger. The filing of the certificate of merger will occur as soon as practicable after satisfaction or waiver of the conditions to the completion of the merger, as described in the merger agreement. As a result of the merger, HeartWare will become a wholly owned subsidiary of Thoratec, all of the outstanding shares of HeartWare common stock will be cancelled and the former HeartWare stockholders will be entitled to receive the merger consideration. Assuming certain tax-related conditions described in the merger agreement are met, immediately following the consummation of the merger, the second merger will become effective upon the filing of a certificate of merger, which we refer to as the second merger certificate of merger, with the Secretary of State of the State of Delaware or at such other time as is agreed upon by HeartWare and Thoratec and specified as the effective time in the second merger certificate of merger.
 
Public Trading Markets
 
HeartWare common stock trades on The NASDAQ Global Market under the symbol “HTWR” and HeartWare CDIs trade on ASX under the symbol “HIN”. Thoratec common stock trades on The NASDAQ Global Select Market under the symbol “THOR”. Upon completion of the merger, HeartWare common stock and HeartWare CDIs will be delisted from the above listed exchanges and deregistered under the Exchange Act. Thoratec will apply


70

to have the shares of Thoratec common stock to be issued in the merger approved for listing on The NASDAQ Global Select Market. Shares of Thoratec common stock will not be listed on ASX.
 
Thoratec’s Dividend Policy
 
The holders of Thoratec common stock receive dividends if and when declared by the Thoratec board of directors. Thoratec has not declared or paid any dividends on its common stock and does not intend to pay dividends in the foreseeable future.
 
Material U.S. Federal Income Tax Consequences
 
The following summary describes the material U.S. federal income tax consequences to holders of HeartWare common stock upon an exchange of their HeartWare common stock for Thoratec common stock and cash in the merger. The following summary is based upon the Internal Revenue Code, existing and proposed Treasury regulations and published administrative rulings and court decisions, all as currently in effect as of the date hereof, and all of which are subject to change, possibly with retroactive effect. The following discussion does not address the following: (i) the tax consequences of the mergers under U.S. federal non-income tax laws or under state, local or non-U.S. tax laws; or (ii) the tax consequences of the ownership or disposition of Thoratec common stock acquired in the merger.
 
Except as specifically set forth below, this discussion addresses only those HeartWare stockholders that are U.S. persons for U.S. federal income tax purposes. You are a U.S. person for purposes of this discussion if you are:
 
  •  a citizen or resident of the United States;
 
  •  a corporation (or an entity treated as a corporation for U.S. federal income tax purposes) created or organized under the laws of the United States or of any state thereof or the District of Columbia;
 
  •  an estate the income of which is subject to U.S. federal income tax regardless of its source; or
 
  •  a trust if (a) (i) a court within the United States is able to exercise primary supervision over the trust, and (ii) one or more U.S. persons have authority to control all substantial decisions of the trust, or (b) the trust has made an election under applicable Treasury regulations to be treated as a U.S. person.
 
This discussion addresses only those HeartWare stockholders that hold their HeartWare common stock as a capital asset within the meaning of Section 1221 of the Internal Revenue Code and does not address all the U.S. federal income tax consequences that may be relevant to particular HeartWare stockholders in light of their individual circumstances or to HeartWare stockholders that are subject to special rules, such as:
 
  •  financial institutions;
 
  •  investors in pass-through entities;
 
  •  insurance companies;
 
  •  tax-exempt organizations;
 
  •  dealers in securities or currencies;
 
  •  traders in securities that elect to use a mark to market method of accounting;
 
  •  persons that hold HeartWare common stock as part of a straddle, hedge, constructive sale or conversion transaction;
 
  •  regulated investment companies;
 
  •  real estate investment trusts;
 
  •  certain U.S. expatriates;
 
  •  persons whose “functional currency” is not the U.S. dollar; and


71


Table of Contents

 
  •  stockholders who acquired their HeartWare common stock through the exercise of an employee stock option or otherwise as compensation.
 
If a partnership (or other entity taxed as a partnership for U.S. federal income tax purposes) holds HeartWare common stock, the tax treatment of a partner in the partnership generally will depend upon the status of the partner and the activities of the partnership. Partnerships and partners in such a partnership should consult their tax advisers about the tax consequences of the mergers to them.
 
Under general U.S. federal income tax principles, a holder of HeartWare CDIs will be treated as the beneficial owner of the corresponding number of shares of HeartWare common stock held by CDN. References to HeartWare common stock in this discussion include HeartWare CDIs.
 
Holders of HeartWare common stock are urged to consult their own tax advisors regarding the U.S. federal income tax consequences of the mergers in light of their personal circumstances and the consequences of the mergers under U.S. federal non-income tax laws and state, local and non-U.S. tax laws.
 
Transaction Structure
 
Pursuant to the merger agreement, the acquisition of HeartWare by Thoratec will be effected either as (i) a transaction structured to qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code, if the value of the stock portion of the merger consideration equals or exceeds 41% of the value of the aggregate merger consideration, in each case as specifically calculated pursuant to relevant provisions in the merger agreement, or (ii) otherwise, a transaction that is not structured to qualify as a “reorganization” and that will be fully taxable to HeartWare stockholders for U.S. federal income tax purposes. Whether the acquisition of HeartWare will be effected as a transaction intended to qualify as a “reorganization” or as a fully taxable transaction will depend in part upon future events that are not within the control of HeartWare or Thoratec, as described in more detail below.
 
Thoratec will notify HeartWare’s stockholders via a press release announcing the consummation of the merger as to whether or not the acquisition of HeartWare by Thoratec has been structured as a “reorganization”.
 
If the “continuity percentage,” as defined in this paragraph and as calculated pursuant to the merger agreement, is at least 41%, then immediately following, and as part of the same plan as, the merger, the second merger will occur. We refer to the condition described in the preceding sentence as the stock value condition. Pursuant to the second merger, HeartWare, the surviving corporation in the merger, will merge with and into a direct, wholly owned subsidiary of Thoratec. The continuity percentage is the percentage obtained by dividing (i) the aggregate value of the Thoratec common stock payable in the merger (valued using the effective stock price, which is the mean between the high and the low selling prices of a share of Thoratec common stock as reported on The NASDAQ Stock Market for the last trading session closing prior to the effective time of the merger), by (ii) the sum of the aggregate value of the Thoratec common stock payable in the merger (valued using the effective stock price) and all other consideration payable to HeartWare stockholders (including for this purpose HeartWare stockholders exercising dissenters’ rights and cash paid in respect of certain HeartWare stock-based awards) in connection with the merger, in each case as calculated pursuant to the merger agreement. Pursuant to the merger agreement, and solely for purposes of determining the continuity percentage, each outstanding share of HeartWare common stock with respect to which dissenters’ rights are exercised will be deemed to receive cash in an amount equal to the sum of the value of the Thoratec common stock (determined using the effective stock price) and cash payable with respect to each non-dissenting HeartWare share in the merger.
 
If the continuity percentage equals or exceeds 41%, the stock value condition will be satisfied and the second merger will occur, in which case (i) Thoratec and HeartWare will treat the merger and the second merger, taken together, as a single integrated transaction for U.S. federal income tax purposes that qualifies as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code, and (ii) as a condition to the completion of the acquisition of HeartWare pursuant to the merger agreement (which condition is not waivable after the receipt of stockholder approval for the merger unless further stockholder approval is obtained with appropriate disclosure), Shearman will deliver a tax opinion to HeartWare, and Latham will deliver a tax opinion to Thoratec, in each case, to the effect that the merger and the second merger, taken together, will constitute a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code. Thus, if the stock value condition is satisfied but the tax opinions are not delivered, the merger will not occur unless further HeartWare stockholder approval is obtained with appropriate disclosure.


72


Table of Contents

 
The tax opinions described in the preceding paragraph will be based on certain assumptions and on representation letters provided by HeartWare and Thoratec. The determination by Shearman and Latham as to whether the merger and the second merger, taken together, will be treated as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code will depend upon the facts and circumstances (including as set forth in the representation letters) and law existing at the effective times of the mergers. It is possible that HeartWare and/or Thoratec will not be able to obtain its respective tax opinion. If any of the representations in the representation letters is or becomes inaccurate, then the tax opinions may no longer be valid. Neither of these tax opinions will be binding on the IRS and will not preclude the IRS from asserting, or a court from sustaining, a contrary conclusion. Neither HeartWare nor Thoratec intends to request any ruling from the IRS as to the U.S. federal income tax consequences of the mergers. Thus, even if the stock value condition is satisfied, there can be no assurance that the merger and the second merger, taken together, will qualify as a “reorganization”.
 
If the continuity percentage is less than 41%, the stock value condition will not be satisfied, the second merger will not occur and the merger will not qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code. In such event, (i) the acquisition of HeartWare will be treated as a transaction that is fully taxable to HeartWare stockholders for U.S. federal income tax purposes, and (ii) the receipt of the tax opinions described above will not be a condition to completing the acquisition of HeartWare pursuant to the merger agreement.
 
Whether the stock value condition is satisfied will depend on the effective stock price. Other relevant factors will include (i) whether there has been any adjustment to the merger consideration as a result of either (x) HeartWare electing to terminate the merger agreement and Thoratec electing to increase the number of shares of Thoratec common stock payable in the merger or (y) Thoratec electing to reduce the number of shares of Thoratec common stock payable in the merger, as described in “The Merger Agreement — Merger Consideration” beginning on page 83 and (ii) the number of outstanding shares of HeartWare common stock with respect to which HeartWare stockholders exercise dissenters’ rights. Accordingly, in deciding whether to vote to adopt the merger agreement, you should consider the possibility that the transaction will be structured as a fully taxable transaction because the stock value condition is not satisfied. You will not be entitled to change your vote or to vote again in the event that the stock value condition is not satisfied and the transaction is structured as a fully taxable transaction for U.S. federal income tax purposes.
 
Based on 8,924,351 shares of HeartWare common stock outstanding as of the record date and restricted stock units representing 82,138 shares of HeartWare common stock outstanding as of the record date, the stock value condition will be satisfied if the effective stock price is at least $16.74 and will not be satisfied if the effective stock price is $16.73 or less, assuming that no HeartWare stockholder exercises dissenters’ rights and assuming that there has been no adjustment to the merger consideration as a result of either (i) HeartWare electing to terminate the merger agreement and Thoratec electing to increase the number of shares of Thoratec common stock payable in the merger or (ii) Thoratec electing to reduce the number of shares of Thoratec common stock payable in the merger, as described in “The Merger Agreement — Merger Consideration” beginning on page 83.
 
The table set forth below shows, given a hypothetical effective stock price reflecting a range of values for Thoratec common stock, the resulting continuity percentage assuming that no HeartWare stockholder exercises dissenters’ rights and the percentage of the outstanding shares of HeartWare common stock with respect to which HeartWare stockholders exercise dissenters’ rights at and above which percentage the stock value condition would not be satisfied. The range of continuity percentages shown in the table below reflects fluctuations in the value of the aggregate stock consideration arising solely from changes in the hypothetical effective stock price.
 
All amounts shown in the table set forth below assume that 0.6054 of a share of HeartWare common stock and $14.30 in cash are payable in the merger for each share of HeartWare common stock and that there has been no adjustment to the merger consideration as a result of either (i) HeartWare electing to terminate the merger agreement and Thoratec electing to increase the number of shares of Thoratec common stock payable in the merger or (ii) Thoratec electing to reduce the number of shares of Thoratec common stock payable in the merger, as described in “The Merger Agreement — Merger Consideration” beginning on page 83. In the event the merger consideration is adjusted as a result of either (i) or (ii), as described in “The Merger Agreement — Merger Consideration” beginning on page 83, the actual continuity percentage would differ from the amounts shown in the

second column of the table set forth below. If HeartWare elects to terminate the merger agreement and Thoratec elects to increase the number of shares of Thoratec common stock payable in the merger as described in “The Merger Agreement — Merger Consideration” beginning on page 83, the actual continuity percentage will be greater than the continuity percentage shown in the table set forth below for any given hypothetical effective stock price because the aggregate merger consideration payable in the form of stock will be greater than it would have been had Thoratec not elected to increase the number of shares of Thoratec common stock payable in the merger, subject to the discussion in the following paragraph. Alternatively, if Thoratec elects to reduce the number of shares of Thoratec common stock payable in the merger as described in “The Merger Agreement — Merger Consideration” beginning on page 83, the continuity percentage will be less than the continuity percentage shown in the table set forth below because a lesser portion of the aggregate merger consideration will be payable in the form of stock consideration.
 
As described in the “The Merger Agreement — Merger Consideration” beginning on page 83, if Thoratec, following HeartWare’s exercise of its option to terminate the merger agreement, then elects to increase the number of shares of Thoratec common stock payable in the merger to the degree that such increase would require Thoratec to issue more than 19.9% of the already outstanding shares of Thoratec common stock, the maximum number of shares that may be issued by Thoratec without requiring the approval of Thoratec’s shareholders under The NASDAQ Stock Market Marketplace Rule 5635 (formerly The NASDAQ Stock Market Marketplace Rule 4350), the aggregate amount of stock consideration payable in the merger will be fixed at 19.9% of the already outstanding shares of Thoratec common stock, and any additional consideration due to HeartWare stockholders will be paid solely in cash in lieu of the issuance of shares of Thoratec common stock, with such cash consideration calculated using the volume weighted average price (as defined in note (3) to the following table) of shares of Thoratec common stock otherwise issuable in the merger. If the cash consideration payable as a portion of the merger consideration is so increased, the actual continuity percentage will be less than the continuity percentage that would otherwise result if the cash consideration portion of the merger consideration were not so increased.
 
The following table is provided for illustrative purposes only. The actual mean between the high and low selling prices of a share of Thoratec common stock as reported on The NASDAQ Stock Market for the last trading session closing prior to the effective time of the merger will determine the actual effective stock price and actual continuity percentage. The actual effective stock price will not be determinable until the close of the last trading session prior to the effective time of the merger. All dollar amounts set forth in the table below have been calculated in U.S. dollars.

(1) The continuity percentage amounts set forth in this column reflect the aggregate value of the stock portion of the merger consideration divided by the sum of the aggregate value of the stock portion of the merger consideration and all other consideration payable to HeartWare stockholders, including cash amounts paid to holders of HeartWare restricted stock units, based on the hypothetical effective stock price set forth in the first

column of the table. Amounts in this column assume that none of the HeartWare stockholders exercise dissenters’ rights. Amounts in this column are rounded to the nearest tenth of a percentage point.
 
In addition, all amounts shown in the table assume that 8,924,351 shares of HeartWare common stock (the number of shares of HeartWare common stock outstanding as of the record date) are outstanding as of the effective time of the merger and that restricted stock units representing 82,138 shares of HeartWare common stock (the number of HeartWare restricted stock units outstanding as of the record date) are outstanding as of the effective time of the merger. All else being equal, a decrease in the number of restricted stock units outstanding will increase the continuity percentage relative to the amount shown in this column. Under the terms of the merger agreement, HeartWare may not issue any additional restricted stock units prior to the closing without the prior written consent of Thoratec.
 
(2) Given a hypothetical effective stock price set forth in the first column of the table, amounts set forth in this column reflect the percentage of the outstanding shares of HeartWare common stock subject to HeartWare stockholders’ exercise of dissenters’ rights at and above which the continuity percentage would be less than 41% and the stock value condition would not be met. Amounts in this column are, unless otherwise noted, expressed to a tenth of a percentage point. If the continuity percentage would be less than 41% and the stock value condition would not be met at the given hypothetical effective stock price set forth in the first column of the table, then this column has been left blank. As noted above, if there has been an adjustment to the merger consideration as a result of either (i) HeartWare electing to terminate the merger agreement and Thoratec electing to increase the number of shares of Thoratec common stock payable in the merger or (ii) Thoratec electing to reduce the number of shares of Thoratec common stock payable in the merger, as described in “The Merger Agreement — Merger Consideration” beginning on page 83, the actual percentage of the outstanding shares of HeartWare common stock subject to HeartWare stockholders’ exercise of dissenters’ rights at and above which the continuity percentage would be less than 41% would differ from the amounts set forth in this column.

(5) Represents the lowest effective stock price at which the stock value condition will be satisfied, assuming no HeartWare stockholder exercises dissenters’ rights.
 
(6) Represents an effective stock price equal to the volume weighted average price at which HeartWare will have the right to terminate the merger agreement unless, within two (2) business days following receipt of HeartWare’s written notice of its election to terminate the merger agreement, Thoratec elects to increase the number of shares of Thoratec common stock payable in the merger.

share of Thoratec common stock payable in the merger is equal to $34.13 (130% of the value of the aggregate Thoratec stock consideration payable in the merger, calculated using the $26.25 price per share of Thoratec common stock used to determine the stock portion of the merger consideration).
 
(12) This amount is expressed to a hundredth of a percentage point.
 
Treatment as a Reorganization
 
Assuming that the stock value condition is satisfied and that the merger and the second merger, taken together, are treated as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code, the following material U.S. federal income tax consequences generally will result:
 
  •  A HeartWare stockholder that exchanges HeartWare common stock for Thoratec common stock and cash pursuant to the merger will recognize gain (but not loss) in an amount equal to the lesser of (i) the amount of cash received in the merger (other than any cash received with respect to a fractional share of Thoratec common stock, which is discussed below) and (ii) an amount equal to the excess, if any, of (x) the sum of the amount of cash and the fair market value of the shares of Thoratec common stock received over (y) the stockholder’s adjusted tax basis in the HeartWare common stock exchanged.
 
  •  The gain recognized will be capital gain unless the receipt of cash by the stockholder has the effect of a distribution of a dividend, in which case such gain will be treated as ordinary dividend income to the extent of the stockholder’s ratable share of accumulated earnings and profits of Thoratec as calculated for U.S. federal income tax purposes. In general, the determination of whether the receipt of cash in the merger will be treated as a dividend for U.S. federal income tax purposes depends upon the extent to which a HeartWare stockholder’s receipt of cash reduces its deemed percentage stock ownership of Thoratec. For purposes of this determination, a HeartWare stockholder will be treated as if it first exchanged all of its HeartWare common stock solely for Thoratec common stock, and then Thoratec immediately redeemed a portion of such Thoratec common stock in exchange for the cash that such stockholder actually received.
 
  •  The deemed redemption will not be treated as a dividend for U.S. federal income tax purposes if it results in a “meaningful reduction” in the stockholder’s deemed percentage stock ownership of Thoratec, taking into account any of such stockholder’s existing ownership of Thoratec common stock and certain constructive ownership rules. The IRS has indicated in rulings that any reduction in the interest of a minority stockholder that owns a small number of shares in a publicly and widely held corporation and that exercises no control over corporate affairs is a “meaningful reduction” resulting in capital gain treatment. In one published ruling, the IRS indicated that a shareholder in a publicly held corporation whose relative stock interest in the corporation is “minimal” and who exercises no control over corporate affairs is treated as having had a meaningful reduction in his or her stock after a redemption transaction if his or her percentage stock ownership in the corporation has been reduced by any extent, taking into account the shareholder’s actual and constructive ownership before and after the hypothetical redemption. In that ruling, a reduction from 0.000118% to 0.0001081% was held to be a meaningful reduction. Each HeartWare stockholder whose deemed percentage stock ownership in Thoratec is not minimal should consult its tax advisor to determine whether the receipt of cash by such stockholder may be treated as a dividend for U.S. federal income tax purposes.
 
  •  A HeartWare stockholder will have an aggregate initial tax basis in the Thoratec common stock received in the merger equal to the stockholder’s aggregate adjusted tax basis in its HeartWare common stock surrendered (i) reduced by the sum of (x) the portion of the stockholder’s adjusted tax basis in its HeartWare common stock surrendered that is allocable to fractional shares of Thoratec common stock for which cash is received and (y) the amount of cash received by the stockholder in the merger and (ii) increased by the amount of gain (including any portion of such gain that is treated as a dividend as described above), if any, recognized by the stockholder (but not including the gain recognized upon the receipt of cash in lieu of fractional shares of Thoratec common stock).
 
  •  The holding period for Thoratec common stock received by a HeartWare stockholder in the merger (including fractional shares of Thoratec common stock deemed received) will include the holding period for the HeartWare common stock surrendered.

Table of Contents

 
  •  If a HeartWare stockholder receives cash in lieu of fractional shares of Thoratec common stock in the merger, the stockholder generally will recognize capital gain or loss equal to the difference between the amount of cash received in lieu of the fractional shares of Thoratec common stock and the portion of the stockholder’s adjusted tax basis in its HeartWare common stock surrendered that is allocable to the fractional shares.
 
Any capital gain that is recognized on the exchanges described above will be long-term capital gain if the stockholder’s holding period with respect to its HeartWare common stock exceeds one (1) year. Long-term capital gains of non-corporate taxpayers currently are taxed at a maximum U.S. federal income tax rate of 15%. Short-term capital gains are taxed at ordinary income rates. Subject to certain exceptions, dividends received by non-corporate stockholders currently are taxed at a maximum U.S. federal income tax rate of 15%, provided certain holding period requirements are met.
 
A HeartWare stockholder who receives Thoratec common stock in the merger will be required to retain records pertaining to the merger. In addition, a HeartWare stockholder who, immediately before the merger, owned at least 5% (by vote or value) of the total outstanding stock of HeartWare is required to attach a statement to its U.S. federal income tax return for the year in which the merger is completed that sets forth such stockholder’s tax basis in its HeartWare common stock surrendered and the fair market value of such stock.
 
If a HeartWare stockholder acquired different blocks of HeartWare common stock at different times or at different prices, any gain will be determined separately with respect to each block of HeartWare common stock, and the cash and shares of Thoratec common stock received in the merger will be allocated on a pro rata basis to each such block of HeartWare common stock.
 
Treatment as a Fully Taxable Transaction
 
If the stock value condition is not satisfied, the second merger will not occur and the merger will not qualify as a “reorganization”. Instead, the merger will be fully taxable for U.S. federal income tax purposes and HeartWare stockholders will be fully subject to tax on the exchange of their HeartWare common stock for Thoratec common stock and cash. In general, each HeartWare stockholder will recognize capital gain or loss in the merger in an amount equal to the difference between (i) the sum of the amount of cash received (including any cash received with respect to a fractional share of Thoratec common stock) and the fair market value of Thoratec common stock received, and (ii) the stockholder’s adjusted tax basis in its HeartWare common stock surrendered. The capital gain or loss will be long-term capital gain or loss if the stockholder had held the HeartWare common stock surrendered for more than one year. Long-term capital gains of non-corporate taxpayers currently are taxed at a maximum U.S. federal income tax rate of 15%. Short-term capital gains are taxed at ordinary income rates. The initial tax basis in the Thoratec common stock received in the merger will be equal to its fair market value and the holding period for such Thoratec common stock will begin the day after the effective time of the merger.
 
If a HeartWare stockholder acquired different blocks of HeartWare common stock at different times or at different prices, any gain or loss will be determined separately with respect to each block of HeartWare common stock, and the cash and shares of Thoratec common stock received in the merger will be allocated on a pro rata basis to each such block of HeartWare common stock.
 
Dissenting HeartWare Stockholders
 
The above discussion does not apply to HeartWare stockholders who properly perfect dissenters’ rights. A HeartWare stockholder who perfects dissenters’ rights with respect to such stockholder’s HeartWare common stock will recognize capital gain or loss equal to the difference between (i) the amount of cash received in exchange for such HeartWare common stock and (ii) such stockholder’s adjusted tax basis in such HeartWare common stock. The capital gain or loss will be long-term capital gain or loss if the stockholder had held such HeartWare common stock surrendered for more than one year. Long-term capital gains of non-corporate taxpayers currently are taxed at a maximum U.S. federal income tax rate of 15%. Short-term capital gains are taxed at ordinary income rates.
 
If a HeartWare stockholder acquired different blocks of HeartWare common stock at different times or at different prices, any gain or loss will be determined separately with respect to each block of HeartWare common stock.

Certain Considerations for Non-U.S. Stockholders
 
This section describes certain considerations for HeartWare stockholders that are not U.S. persons, which we will refer to as non-U.S. stockholders.
 
Any capital gain recognized by a non-U.S. stockholder as a result of the exchange of HeartWare common stock in the merger generally will not be subject to U.S. federal income tax unless: (i) the gain is effectively connected with the conduct of a trade or business in the United States and, if an applicable income tax treaty applies, is attributable to a U.S. permanent establishment of the non-U.S. stockholder (in this case, such non-U.S. stockholder will be subject to U.S. federal income tax on the net gain derived from the disposition in the same manner as if the non-U.S. stockholder was a U.S. person, and if the non-U.S. stockholder is a corporation, it may be subject to the additional “branch profits tax” at a 30% rate or a lower rate specified by an applicable income tax treaty); (ii) the non-U.S. stockholder is an individual present in the United States for 183 days or more in the taxable year in which the disposition occurs and certain other conditions are met (in this case, the individual non-U.S. stockholder will be subject to a flat 30% U.S. federal income tax on the gain derived from the disposition, which tax may be offset by U.S. source capital losses); or (iii) HeartWare is or has been a “U.S. real property holding corporation” for U.S. federal income tax purposes and one or more other conditions are satisfied (HeartWare has provided a representation in the merger agreement to the effect that it is not and has not been a “U.S. real property holding corporation”).
 
To the extent the receipt of cash by a non-U.S. stockholder is treated as a dividend for U.S. federal income tax purposes as described above in “— Treatment as a Reorganization”, the dividend generally will be subject to withholding of U.S. federal income tax at a 30% rate unless such withholding rate is reduced by an applicable income tax treaty. In order for a non-U.S. stockholder to claim benefits under an applicable income tax treaty in respect of a dividend, the non-U.S. stockholder generally will be required to provide a completed IRS Form W-8BEN and certify under penalties of perjury that it is not a U.S. person.
 
Backup Withholding
 
Certain HeartWare stockholders may be subject to backup withholding of U.S. federal income tax, at a rate of 28%, with respect to the consideration received pursuant to the merger. Backup withholding will not apply, however, to a HeartWare stockholder that (i) is a U.S. person and furnishes a correct taxpayer identification number and certifies that it is not subject to backup withholding on IRS Form W-9 or a substantially similar form, (ii) provides a certification of its status as a non-U.S. stockholder on an appropriate IRS Form W-8 or successor form or (iii) is otherwise exempt from backup withholding, such as a corporation, and provides appropriate proof of the applicable exemption. Any amounts withheld from payments to a HeartWare stockholder under the backup withholding rules are not an additional tax and will be allowed as a refund or credit against the HeartWare stockholder’s U.S. federal income tax liability, if any, provided that the HeartWare stockholder timely furnishes the required information to the IRS.
 
THE FOREGOING DISCUSSION IS INTENDED ONLY AS A SUMMARY. HOLDERS OF HEARTWARE COMMON STOCK ARE URGED TO CONSULT THEIR OWN TAX ADVISORS REGARDING THE U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE MERGERS IN LIGHT OF THEIR PERSONAL CIRCUMSTANCES AND THE CONSEQUENCES OF THE MERGERS UNDER U.S. FEDERAL NON-INCOME TAX LAWS AND STATE, LOCAL AND NON-U.S. TAX LAWS.
 
Regulatory Matters
 
Both HeartWare and Thoratec have agreed to use their respective reasonable best efforts to prepare and file as soon as practicable all forms, registrations and notices relating to antitrust, competition, trade or other regulatory matters and to take any such actions as are reasonably necessary to obtain any regulatory approvals required to complete the transactions contemplated by the merger agreement, including any notification and report forms and related material required to be filed pursuant to the HSR Act with the FTC and with the Antitrust Division. HeartWare and Thoratec have completed the initial filing of applications and notifications to obtain the expiration or termination of the waiting period under the HSR Act and, as discussed below, HeartWare and Thoratec have both substantially complied with the second request and the parties are waiting for a final determination from the FTC.

United States Antitrust Approval
 
Under the provisions of the HSR Act and related rules, certain transactions, including the merger, may not be completed until each party has filed its notification and report form with the FTC and the Antitrust Division and the HSR Act thirty (30) calendar-day waiting period has expired or been terminated early. HeartWare and Thoratec each filed their respective notification and report forms with the FTC and the Antitrust Division regarding the merger under the HSR Act on February 24, 2009. On March 26, 2009, each of HeartWare and Thoratec received a request for additional information, or a second request, from the FTC. The effect of the second request is to extend the waiting period for the merger under the HSR Act until thirty (30) calendar days after Thoratec and HeartWare have substantially complied with the second request, unless that period is extended voluntarily by Thoratec and HeartWare or terminated sooner by the FTC. HeartWare and Thoratec have both substantially complied with the second request and the parties are waiting for a final determination from the FTC. At any time before or after the effective time of the merger, the FTC, or others (including state attorney generals and private parties) could take action under the antitrust laws as they deem necessary or desirable in the public interest, including seeking to prevent the merger, to rescind the merger or to conditionally approve the merger upon the divestiture of assets of HeartWare or Thoratec or their subsidiaries.
 
Under the terms of the merger agreement, neither Thoratec nor HeartWare is obligated to consent to or to effect any divestiture or hold separate-order or enter into any license or similar agreement with respect to, or agree to restrict its ownership or operation of, any of its business or assets of that of either Thoratec, HeartWare or any of its affiliates or subsidiaries, in order to consummate the mergers. We cannot assure that a challenge to the merger on antitrust grounds will not be made or, if a challenge is made, of the results of such challenge. Similarly, we cannot assure that HeartWare or Thoratec will obtain the regulatory approvals necessary to consummate the merger or that the granting of these approvals will not involve the imposition of conditions to the consummation of the merger or require changes to the terms of the merger. These conditions or changes could result in the conditions to the merger not being satisfied prior to the termination date or at all. See the section entitled “Risk Factors” beginning on page 25.
 
Dissenters’ Rights
 
Holders of record of shares of HeartWare common stock who do not vote in favor of the adoption of the merger agreement and who properly demand an “appraisal” of the “fair value” of their shares will be entitled to dissenters’ rights in connection with the merger under Section 262 of the Delaware General Corporation Law, which we refer to as Section 262.
 
The following discussion is not a complete statement of the law pertaining to dissenters’ rights under Section 262 and is qualified in its entirety by the full text of Section 262 which is attached to this proxy statement/prospectus as Annex G. The following summary does not constitute any legal or other advice nor does it constitute a recommendation that stockholders exercise their dissenters’ rights under Section 262. All references in Section 262 and in this summary to a “stockholder” or “holders of shares of HeartWare common stock” are to the record holder or holders of the shares of HeartWare common stock as to which dissenters’ rights are asserted. A person having a beneficial interest in shares of HeartWare common stock held of record in the name of another person, such as a broker, fiduciary, depositary or other nominee, must act promptly to cause the record holder to follow the steps summarized below properly and in a timely manner to perfect dissenters’ rights.
 
Under Section 262, a record holder of shares of HeartWare common stock who makes the demand described below with respect to such shares, who continuously is the record holder of such shares through the effective time of the merger, who does not vote in favor of the adoption of the merger agreement and who otherwise follows the procedures set forth in Section 262 will be entitled to have his or her shares appraised by the Delaware Court of Chancery and to receive payment in cash of the “fair value” of the shares, exclusive of any element of value arising from the accomplishment or expectation of the merger, together with interest, if any, to be paid upon the amount determined to be the fair value.
 
Under Section 262, where a merger is to be submitted for approval at a meeting of stockholders, as in the case of the adoption of the merger agreement by HeartWare stockholders, the corporation, not less than twenty (20) days prior to the meeting, must notify each of its stockholders entitled to dissenters’ rights that dissenters’ rights are available and include in the notice a copy of Section 262. This proxy statement/prospectus constitutes the notice,


79


Table of Contents

and the full text of Section 262 is attached to this proxy statement/prospectus as Annex G. Any holder of HeartWare common stock who wishes to exercise dissenters’ rights, or who wishes to preserve such holder’s right to do so, should review the following discussion and Annex G carefully because failure to timely and properly comply with the procedures specified will result in the loss of dissenters’ rights. Moreover, because of the complexity of the procedures for exercising the right to seek appraisal of shares of HeartWare common stock, we believe that if you are considering exercising such rights, you should seek the advice of legal counsel.
 
Any stockholder wishing to exercise dissenters’ rights must deliver to HeartWare, before the vote on the adoption of the merger agreement at the HeartWare special meeting on • , 2009, at • , U.S. Eastern time ( • , Australia Eastern Standard Time on • , 2009), a written demand for the appraisal of the stockholder’s shares, and that holder of shares of HeartWare common stock must not vote in favor of the adoption of the merger agreement. A holder of shares of HeartWare common stock wishing to exercise dissenters’ rights must hold the shares of record on the date the written demand for appraisal is made and must continue to hold the shares of record through the effective date of the merger, since dissenters’ rights will be lost if the shares are transferred prior to the effective time of the merger. A proxy which is properly executed and does not contain voting instructions will, unless revoked, be voted in favor of the adoption of the merger agreement, and it will constitute a waiver of the stockholder’s right of appraisal and will nullify any previously delivered written demand for appraisal. Therefore, a stockholder who votes by proxy and who wishes to exercise dissenters’ rights must vote against the adoption of the merger agreement or abstain from voting on the adoption of the merger agreement. Neither voting against the adoption of the merger agreement (in person or by proxy) nor abstaining from voting or failing to vote on the proposal to adopt the merger will in and of itself constitute a written demand for appraisal satisfying the requirements of Section 262. The written demand for appraisal must be in addition to and separate from any proxy or vote. The demand must reasonably inform HeartWare of the identity of the record holder as well as the intention of the holder to demand an appraisal of the “fair value” of the shares held by the holder. A stockholder’s failure to make the written demand prior to the taking of the vote on the adoption of the merger agreement at the special meeting of stockholders will constitute a waiver of dissenters’ rights.
 
Only a holder of record of shares of HeartWare common stock is entitled to assert dissenters’ rights for the shares registered in that holder’s name. A demand for appraisal in respect of shares of HeartWare common stock should be executed by or on behalf of the holder of record, fully and correctly, as the holder’s name appears on the holder’s stock certificates, should specify the holder’s name and mailing address and the number of shares registered in the holder’s name and must state that the person intends thereby to demand appraisal of the holder’s shares in connection with the merger. If the shares are owned of record by a person other than the beneficial owner, including a broker, fiduciary (such as a trustee, guardian or custodian), depositary or other nominee, execution of the demand should be by or for the record owner, and if the shares are owned of record by more than one person, as in a joint tenancy and tenancy in common, the demand should be executed by or on behalf of all joint owners. An authorized agent, including an agent for two or more joint owners, may execute a demand for appraisal on behalf of a holder of record; however, the agent must identify the record owner or owners and expressly disclose that, in executing the demand, the agent is acting as agent for the record owner or owners. A record holder such as a broker who holds shares as nominee for several beneficial owners may exercise dissenters’ rights with respect to the shares held for one or more beneficial owners while not exercising the rights with respect to the shares held for other beneficial owners; in such case, however, the written demand should set forth the number of shares as to which appraisal is sought, and where no number of shares is expressly mentioned the demand will be presumed to cover all shares of HeartWare common stock held in the name of the record owner. Stockholders who hold their shares in brokerage accounts or other nominee forms and who wish to exercise dissenters’ rights are urged to consult with their brokers to determine the appropriate procedures for the making of a demand for appraisal by such a nominee.
 
All written demands for appraisal pursuant to Section 262 should be sent or delivered to HeartWare at 205 Newbury Street, Framingham, Massachusetts 01701, Attention: David McIntyre, Chief Financial Officer and Company Secretary.
 
At any time within sixty (60) days after the effective date of the merger, any holder of HeartWare common stock who has not commenced an appraisal proceeding or joined that proceeding as a named party may withdraw his, her or its demand for appraisal and accept the merger consideration offered pursuant to the merger agreement by delivering to the surviving corporation a written withdrawal of the demand for appraisal. However, any such attempt


80


Table of Contents

to withdraw the demand made more than sixty (60) days after the effective date of the merger will require written approval of the surviving corporation. No appraisal proceeding in the Delaware Court of Chancery will be dismissed as to any stockholder without the approval of the Delaware Court of Chancery, and such approval may be conditioned upon such terms as the court deems just; provided, however, that any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party may withdraw his, her or its demand for appraisal and accept the merger consideration offered pursuant to the merger agreement within sixty (60) days after the effective date of the merger. If the surviving corporation does not approve a request to withdraw a demand for appraisal when that approval is required, or, except with respect to any stockholder who withdraws such stockholder’s right to appraisal in accordance with the proviso in the immediately preceding sentence, if the Delaware Court of Chancery does not approve the dismissal of an appraisal proceeding, the stockholder will be entitled to receive only the appraised value determined in any such appraisal proceeding, which value could be less than, equal to or more than the merger consideration being offered pursuant to the merger agreement.
 
Within ten (10) days after the effective date of the merger, the surviving corporation must notify each holder of HeartWare common stock who has complied with Section 262 and who has not voted in favor of the adoption of the merger agreement, that the merger has become effective. Within 120 days after the effective date of the merger, but not thereafter, the surviving corporation or any holder of HeartWare common stock who has so complied with Section 262 and is entitled to dissenters’ rights under Section 262 may commence an appraisal proceeding by filing a petition in the Delaware Court of Chancery with a copy served on the surviving corporation demanding a determination of the fair value of the shares held by all dissenting holders. If a petition for appraisal is not timely filed, then the right to an appraisal for all dissenting stockholders will cease. The surviving corporation is under no obligation to and has no present intention to file a petition, and holders should not assume that the surviving corporation will file a petition or that the surviving corporation will initiate any negotiations with respect to the fair value of such shares. Accordingly, it is the obligation of the holders of HeartWare common stock who desire to have their shares appraised to initiate all necessary action to perfect their dissenters’ rights in respect of shares of HeartWare common stock within the time and in the manner prescribed in Section 262.
 
Within one hundred and twenty (120) days after the effective date of the merger, any holder of HeartWare common stock who has complied with the requirements for exercise of dissenters’ rights will be entitled, upon written request, to receive from the surviving corporation a statement setting forth the aggregate number of shares not voted in favor of the adoption of the merger agreement and with respect to which demands for appraisal have been received and the aggregate number of holders of such shares. The statement must be mailed within ten (10) days after a written request therefore has been received by the surviving corporation or within ten (10) days after the expiration of the period for delivery of demands for appraisal, whichever is later. Notwithstanding the foregoing, a person who is the beneficial owner of shares of common stock of HeartWare held either in a voting trust or by a nominee on behalf of such person may, in such person’s own name, file a petition or request from HeartWare the statement described in this paragraph.
 
Under the merger agreement, we have agreed to provide Thoratec notice of any demands for appraisal received by us. Thoratec will have the right to participate in all negotiations and proceedings with respect to demands for appraisal under Section 262. We will not make any payments with respect to, or settle or offer to settle, any demand for appraisal without the written consent of Thoratec.
 
If a petition for an appraisal is timely filed by a holder of shares of HeartWare common stock and a copy thereof is served upon the surviving corporation, the surviving corporation will then be obligated within twenty (20) days to file with the Delaware Register in Chancery a duly verified list containing the names and addresses of all stockholders who have demanded an appraisal of their shares and with whom agreements as to the value of their shares have not been reached. After notice to the stockholders as required by the court, the Delaware Court of Chancery is empowered to conduct a hearing on the petition to determine those stockholders who have complied with Section 262 and who have become entitled to dissenters’ rights thereunder. The Delaware Court of Chancery may require the stockholders who demanded payment for their shares to submit their stock certificates to the Delaware Register in Chancery for notation thereon of the pendency of the appraisal proceedings; and if any stockholder fails to comply with the direction, the Delaware Court of Chancery may dismiss the proceedings as to the stockholder.

Table of Contents

After the Delaware Court of Chancery determines the holders of HeartWare common stock entitled to appraisal, appraisal proceedings shall be conducted in accordance with the rules of the Delaware Court of Chancery, including any rules specifically governing appraisal proceedings. Through such proceedings, the court will determine the “fair value” of shares, exclusive of any element of value arising from the accomplishment or expectation of the merger, together with interest, if any, to be paid upon the amount determined to be the fair value. Unless the court in its discretion determines otherwise for good cause shown, interest from the effective date of the merger through the date of payment of the judgment shall be compounded quarterly and shall accrue at 5% over the federal reserve discount rate (including any surcharge) as established from time to time during the period between the effective date of the merger and the date of payment of the judgment. In determining fair value, the Delaware Court of Chancery will take into account all relevant factors. In Weinberger v. UOP, Inc., the Delaware Supreme Court discussed the factors that could be considered in determining fair value in an appraisal proceeding, stating that “proof of value by any techniques or methods which are generally considered acceptable in the financial community and otherwise admissible in court” should be considered and that “[f]air price obviously requires consideration of all relevant factors involving the value of a company”. The Delaware Supreme Court stated that, in making this determination of fair value, the court must consider market value, asset value, dividends, earnings prospects, the nature of the enterprise and any other facts that could be ascertained as of the date of the merger that throw any light on future prospects of the merged corporation. Section 262 provides that fair value is to be “exclusive of any element of value arising from the accomplishment or expectation of the merger”. In Cede & Co. v. Technicolor, Inc., the Delaware Supreme Court stated that such exclusion is a “narrow exclusion [that] does not encompass known elements of value,” but which rather applies only to the speculative elements of value arising from such accomplishment or expectation. In Weinberger, the Delaware Supreme Court also stated that “elements of future value, including the nature of the enterprise, which are known or susceptible of proof as of the date of the merger and not the product of speculation, may be considered”.
 
Stockholders considering seeking appraisal should be aware that the fair value of their shares as so determined could be more than, the same as or less than the merger consideration they would receive pursuant to the merger if they did not seek appraisal of their shares and that an investment banking opinion as to the fairness from a financial point of view of the consideration to be received in a merger is not necessarily an opinion as to fair value under Section 262. Although we believe that the merger consideration is fair, no representation is made as to the outcome of the appraisal of fair value as determined by the Delaware Court of Chancery, and stockholders should recognize that such an appraisal could result in a determination of a value higher or lower than, or the same as, the merger consideration. Neither Thoratec nor HeartWare anticipate offering more than the applicable merger consideration to any holder of common stock of HeartWare exercising appraisal rights, and Thoratec and HeartWare reserve the right to assert, in any appraisal proceeding, that for purposes of Section 262, the “fair value” of a share of HeartWare common stock is less than the merger consideration. The Delaware courts have stated that the methods which are generally considered acceptable in the financial community and otherwise admissible in court may be considered in the appraisal proceedings. In addition, the Delaware courts have decided that the statutory appraisal remedy, depending on factual circumstances, may or may not be a dissenting stockholder’s exclusive remedy. The costs of the action may be determined by the court and taxed upon the parties as the court deems equitable under the circumstances. However, costs do not include attorneys’ and expert witness fees. Each dissenting stockholder is responsible for his or her attorneys’ and expert witness expenses, although upon application of a dissenting stockholder or the surviving corporation, the Delaware Court of Chancery may also order that all or a portion of the expenses incurred by a stockholder in connection with an appraisal, including, without limitation, reasonable attorneys’ fees and the fees and expenses of experts utilized in the appraisal proceeding, be charged pro rata against the value of all the shares entitled to be appraised.
 
Any holder of shares of HeartWare common stock who has duly demanded an appraisal in compliance with Section 262 will not, after the effective date of the merger, be entitled to vote the shares subject to the demand for any purpose or be entitled to the payment of dividends or other distributions on those shares (except dividends or other distributions payable to holders of record of HeartWare common stock as of a record date prior to the effective time of the merger).
 
If any stockholder who demands appraisal of shares of HeartWare common stock under Section 262 fails to perfect, successfully withdraws or loses such holder’s right to appraisal, then as of the later of the occurrence of such event or the


82


Table of Contents

effective date of the merger, the stockholder’s shares of HeartWare common stock will be deemed to have been converted at the effective time of the merger into and represent solely the right to receive the merger consideration, without interest, pursuant to the merger agreement. A stockholder will fail to perfect, or effectively lose, the holder’s right to appraisal if no petition for appraisal is filed within one hundred and twenty (120) days after the effective date of the merger. In addition, as indicated above, a stockholder may withdraw his, her or its demand for appraisal in accordance with Section 262 and accept the merger consideration offered pursuant to the merger agreement.
 
Failure to comply with all of the procedures set forth in Section 262 will result in the loss of a stockholder’s statutory dissenters’ rights. Consequently, any stockholder wishing to exercise dissenters’ rights is urged to consult legal counsel before attempting to exercise those rights.
 
Holders of HeartWare CDIs are not entitled to exercise dissenters’ rights in connection with the merger. Holders of HeartWare CDIs must have converted their HeartWare CDIs into shares of HeartWare common stock prior to the record date for the HeartWare special meeting in order to have dissenters’ rights in connection with the merger.
 
THE MERGER AGREEMENT
 
This section of the proxy/statement prospectus describes the material provisions of the merger agreement but does not purport to describe all of the terms of the merger agreement. The following summary is qualified in its entirety by reference to the complete text of the merger agreement, which is attached as Annex A to this proxy statement/prospectus. We urge you to read the full text of the merger agreement because it is the legal document that governs the mergers. The merger agreement and the discussion under the heading “The Merger Agreement” have been included to provide you with information regarding the terms of the merger agreement. They are not intended to provide any other factual information about HeartWare and Thoratec. That information can be found elsewhere in this proxy statement/prospectus and in the other public filings made by HeartWare or Thoratec with the SEC, which are available without charge. See “Where You Can Find More Information” beginning on page 127.
 
The merger agreement contains representations and warranties the parties made to each other as of specific dates. The assertions embodied in those representations and warranties were made solely for purposes of the contract between HeartWare and Thoratec and may be subject to important qualifications and limitations agreed to by HeartWare and Thoratec in connection with negotiating its terms. Moreover, certain representations and warranties may not be accurate or complete as of any specified date because they are subject to a contractual standard of materiality different from those generally applicable to stockholders or were used for the purpose of allocating risk between HeartWare and Thoratec rather than establishing matters as facts. For the foregoing reasons, you should not rely on the representations and warranties as statements of factual information.
 
The Mergers
 
Pursuant to the merger agreement, Merger Subsidiary will merge with and into HeartWare, with HeartWare surviving the merger as a wholly owned subsidiary of Thoratec, which we refer to as the intermediate surviving corporation. Provided that the value of the stock consideration is at least 41% of the aggregate merger consideration at closing, then immediately following the merger, HeartWare will merge with and into Merger Subsidiary Two with Merger Subsidiary Two surviving the second merger as a subsidiary of Thoratec, which we refer to as the surviving corporation.
 
Merger Consideration
 
At the effective time, each share of HeartWare common stock issued and outstanding immediately prior to the effective time, including shares of common stock underlying HeartWare CDIs, will be automatically converted into the right to receive (i) $14.30 in cash, without interest, and (ii) 0.6054 shares of common stock of Thoratec, other than:
 
  •  shares held in the treasury of HeartWare or owned by Thoratec, Merger Subsidiary or Merger Subsidiary Two, which shares will be cancelled; and
 
  •  shares held by holders who have properly demanded and perfected their dissenters’ rights.

Thoratec will not issue any fractional shares of Thoratec common stock in the merger. Instead, a HeartWare stockholder who otherwise would have received a fraction of a share of Thoratec common stock will receive an amount in cash, without interest, in lieu thereof equal to such holder’s proportionate interest in the net proceeds from the sale or sales by the exchange agent on behalf of such holder of the aggregate fractional shares of Thoratec common stock that such holder otherwise would be entitled to receive. As soon as practicable after the exchange agent determines the amount of cash to be paid to former HeartWare stockholders (and, to the extent applicable, holders of HeartWare CDIs) in respect of any fractional shares of Thoratec common stock, the exchange agent will distribute such amounts to such former holders in cash rounded to the nearest cent.
 
In addition, if the volume weighted average of the per share closing prices of Thoratec common stock on The NASDAQ Stock Market for the twenty (20) consecutive trading days ending on and including the fifth (5th) trading day prior to, but not including, the closing date of the merger is less than or equal to $18.38 per share, or 70% of $26.25, the Thoratec per share price used to determine the merger consideration, then HeartWare will have an option to terminate the merger agreement unless within two (2) business days following receipt of HeartWare’s written notice of its election to terminate the merger agreement, Thoratec elects to increase the number of shares of Thoratec common stock payable in the merger such that the value of the stock portion of the merger consideration at closing is equal to 70% of the value of the aggregate Thoratec stock consideration payable in the merger (calculated using the $26.25 price per share of Thoratec common stock used to determine the stock portion of the merger consideration). If that same volume weighted average price is greater than or equal to $34.13 per share, or 130% of $26.25, then Thoratec may reduce the number of shares of Thoratec common stock payable in the merger such that the value of the stock portion of the merger consideration at closing is equal to 130% of the value of the aggregate Thoratec stock consideration payable in the merger (calculated using the $26.25 price per share of Thoratec common stock used to determine the stock portion of the merger consideration).
 
If Thoratec, following HeartWare’s exercise of its option to terminate the merger agreement, then elects to increase the number of shares of Thoratec common stock payable in the merger to the degree that such increase would require Thoratec to issue more than 19.9% of the already outstanding shares of Thoratec common stock, and would therefore, require the approval of Thoratec’s shareholders under The NASDAQ Stock Market Marketplace Rule 5635 (formerly The NASDAQ Market Marketplace Rule 4350), the number of shares payable in the merger will instead be increased to equal the maximum number of shares that may be issued without requiring the approval of Thoratec’s shareholders and the additional consideration due to HeartWare stockholders resulting from Thoratec’s exercise of its election to increase the stock portion of the merger consideration would be paid in cash in an amount equal to the product of (i) the number of shares above such 19.9% that would have otherwise been issued as merger consideration and (ii) the volume weighted average of the per share closing prices of Thoratec common stock on The NASDAQ Stock Market for the twenty (20) consecutive trading days ending on and including the fifth (5th) trading day prior to, but not including, the closing date of the merger.
 
Set forth below is a table illustrating the value of the merger consideration that would be payable, at the effective time of the merger, to holders of HeartWare common stock issued and outstanding immediately prior to the effective time of the merger, including shares of common stock underlying HeartWare CDIs, based on a range of values of Thoratec common stock reflecting a hypothetical volume weighted average of the per share closing prices of Thoratec common stock on The NASDAQ Stock Market for the twenty (20) consecutive trading days ending on and including the fifth (5th) trading day prior to, but not including, the closing date of the merger, or the volume weighted average price. The hypothetical consideration amounts provided in the table below include the aggregate value of the cash and stock consideration that would be payable to holders of HeartWare common stock issued and outstanding immediately prior to the effective time of the merger, based on each hypothetical value.
 
With the exception of the consideration payable to HeartWare stockholders in the event that the volume weighted average price equals $8.79 or less, the range of consideration payable in the merger shown in the table below reflects fluctuations in the value of the aggregate stock consideration; the value of the per share cash consideration payable in the merger does not vary from $14.30 per share of HeartWare common stock. If the volume weighted average price is equal to or less than $8.79 (subject to adjustments depending on the number of shares of Thoratec common stock reserved for issuance to holders of unvested and outstanding HeartWare incentive options pursuant to the merger agreement as described below under the heading “— Treatment of Options and Other Equity-Based Awards”), the aggregate amount of stock consideration payable in the merger will be fixed at 19.9%

of the then outstanding shares of Thoratec common stock, the maximum number of shares that may be issued by Thoratec without requiring the approval of Thoratec’s shareholders under The NASDAQ Stock Market Marketplace Rule 5635 (formerly The NASDAQ Stock Market Marketplace Rule 4350) and any additional consideration due to HeartWare stockholders will be paid solely in cash in lieu of issuance of shares of Thoratec common stock.
 
The following table is provided for illustrative purposes only. The actual prices at which shares of Thoratec common stock trade during the twenty (20) consecutive trading day measurement period will determine the actual volume weighted average price and the value of the consideration payable in the merger as of the effective time of the merger. The actual volume weighted average price will not be determinable until five (5) trading days prior to the closing date of the merger. All dollar amounts set forth in the table below have been calculated in U.S. dollars, and as a result, fluctuations in exchange rates between the U.S. dollar and the Australian dollar may materially and adversely affect the value, in Australian dollars, of the cash and Thoratec common stock received by Australian holders of HeartWare common stock or HeartWare CDIs in the merger.

(1) Amounts in this column reflect the cash and stock portions of the merger consideration, but do not reflect amounts to be paid to HeartWare stockholders if, following HeartWare’s election to terminate the merger agreement, Thoratec exercises its right to increase the stock consideration payable in the merger. As of February 12, 2009, the date of execution of the merger agreement, the value of the aggregate merger consideration payable by Thoratec in the merger was $30.19 per share of HeartWare common stock.
 
(2) If the volume weighted average price is less than or equal to $18.38 per share, or 70% of $26.25 (the price per share of Thoratec common stock used to determine the stock portion of the merger consideration), HeartWare will have the right to terminate the merger agreement unless, within two (2) business days following receipt of HeartWare’s written notice of its election to terminate the merger agreement, Thoratec elects to increase the number of shares of Thoratec common stock payable in the merger such that the per share value of Thoratec common stock payable in the merger, at the effective time, is equal to $18.38 (70% of $26.25, the price per share of Thoratec common stock used to determine the stock portion of the merger consideration). If HeartWare does not elect to terminate the merger agreement (and thus Thoratec does not increase the number of shares of Thoratec common stock payable in the merger), HeartWare stockholders will receive, for each share of HeartWare common stock, including shares of HeartWare common stock represented by HeartWare CDIs, $14.30 in cash and 0.6054 of a share of Thoratec common stock (which may reflect a value per share of Thoratec common stock, as of the effective time of the merger, of less than $18.38). If HeartWare elects to terminate the merger agreement and Thoratec does not elect to increase the number of shares of Thoratec common stock payable in the merger, the merger agreement will be terminated and no merger consideration will be paid to HeartWare stockholders.
 
(3) If the volume weighted average price is equal to or less than $8.79 (subject to adjustments depending on the number of shares of Thoratec common stock reserved for issuance to holders of unvested and outstanding HeartWare incentive options pursuant to the merger agreement as described below under the heading “— Treatment of Options and Other Equity-Based Awards”), the aggregate amount of stock consideration payable in the merger will be fixed at 19.9% of the already outstanding shares of Thoratec common stock and


85


Table of Contents

any additional consideration due to HeartWare stockholders will be paid solely in cash in lieu of the issuance of shares of Thoratec common stock, with such cash consideration calculated using the volume weighted average price of shares of Thoratec common stock otherwise issuable in the merger.
 
(4) If the volume weighted average price is $15.00, which is less than $18.38 per share, or 70% of $26.25 (the price per share of Thoratec common stock used to determine the stock portion of the merger consideration), HeartWare will have the right to terminate the merger agreement unless, within two (2) business days following receipt of HeartWare’s written notice of its election to terminate the merger agreement, Thoratec elects to increase the number of shares of Thoratec common stock payable in the merger such that the per share value of Thoratec common stock is equal to $18.38 (70% of $26.25, the price per share of Thoratec common stock used to determine the stock portion of the merger consideration). If HeartWare does not elect to terminate the merger agreement (and thus Thoratec does not increase the number of shares of Thoratec common stock payable in the merger), HeartWare stockholders will receive, for each share of HeartWare common stock, including shares of HeartWare common stock represented by HeartWare CDIs, $14.30 in cash and 0.6054 of a share of Thoratec common stock (which may reflect a value per share of Thoratec common stock, as of the effective time of the merger, of less than $18.38). If HeartWare elects to terminate the merger agreement and Thoratec does not elect to increase the number of shares of Thoratec common stock payable in the merger, the merger agreement will be terminated and no merger consideration will be paid to HeartWare stockholders.
 
(5) One cent less than $18.38, which is 70% of $26.25, the price per share of Thoratec common stock used to determine the stock portion of the merger consideration and the highest volume weighted average price that gives HeartWare the right to terminate the merger agreement, and following the exercise by HeartWare of this right, Thoratec the opportunity to elect to increase the stock consideration. Although HeartWare may terminate the merger agreement if the volume weighted average price is equal to $18.38, the exercise by Thoratec of its election to increase shares pursuant to the terms of the merger agreement at such a volume weighted average price would not result in additional consideration to be paid to HeartWare shareholders; $18.37 is the highest volume weighted average price at which Thoratec’s election to increase the stock consideration will result in additional consideration to be paid to HeartWare stockholders. If HeartWare does not elect to terminate the merger agreement (and thus Thoratec does not increase the number of shares of Thoratec common stock payable in the merger), HeartWare stockholders will receive, for each share of HeartWare common stock, including shares of HeartWare common stock represented by HeartWare CDIs, $14.30 in cash and 0.6054 of a share of Thoratec common stock (which may reflect a value per share of Thoratec common stock, as of the effective time of the merger, of less than $18.38). If HeartWare elects to terminate the merger agreement, and Thoratec does not elect to increase the number of shares of Thoratec common stock payable in the merger, the merger agreement will be terminated and no merger consideration will be paid to HeartWare stockholders.

(7) The average of the high and low closing price per share of Thoratec’s common stock, as reported by The NASDAQ Global Select Market for the period from February 12, 2009 (the date of execution of the merger agreement) to July 2, 2009.
 
(8) The closing price per share of Thoratec common stock, as reported by The NASDAQ Global Select Market, on July 2, 2009.
 
(9) The high closing price per share of Thoratec’s common stock, as reported by The NASDAQ Global Select Market for the period from February 12, 2009 (the date of execution of the merger agreement) to July 2, 2009.
 
(10) 130% of $26.25, the price per share of Thoratec common stock used to determine the stock portion of the merger consideration. If the volume weighted average price is above $34.13, Thoratec may elect to reduce the number of shares of Thoratec common stock payable in the merger such that the value per share of Thoratec common stock payable in the merger is equal to $34.13 (130% of the value of the aggregate Thoratec stock consideration payable in the merger, calculated using the $26.25 price per share of Thoratec common stock used to determine the stock portion of the merger consideration). If the volume weighted average price is above $34.13 and Thoratec elects to reduce the number of shares of Thoratec common stock such that the


86


Table of Contents

value per share of Thoratec common stock payable in the merger is equal to $34.13, the aggregate number of shares of Thoratec common stock issued as merger consideration will decrease as the volume weighted average price increases such that the total consideration payable to HeartWare shareholders will remain the same as the total consideration displayed in the table for the volume weighted average price of $34.13.
 
The calculations presented in the table set forth above assume 8,866,702 outstanding shares of HeartWare common stock, 56,417,263 outstanding shares of Thoratec common stock, the number of outstanding shares of each of HeartWare and Thoratec as of February 11, 2009 and solely for purposes of calculating the maximum number of shares that may be issued by Thoratec without requiring the approval of Thoratec’s shareholders under The NASDAQ Stock Market Marketplace Rule 5635 (previously The NASDAQ Stock Market Marketplace Rule 4350) at the volume weighted average price of $8.79, 20,000 shares of Thoratec common stock reserved for issuance to holders of unvested and outstanding HeartWare incentive options pursuant to the merger agreement as described below under the heading “— Treatment of Options and Other Equity-Based Awards”. The calculations presented in the table set forth above do not reflect amounts payable to holders of HeartWare restricted stock, options or other equity-based awards at the effective time of the merger described under the heading “— Treatment of Options and Other Equity-Based Awards” below.
 
If the number of shares of HeartWare or Thoratec capital stock outstanding changes before the merger is completed for any reason, including by reason of any reclassification, recapitalization, stock split or combination, exchange or readjustment of shares or any stock dividend thereon with a record date during such period, but excluding any change that results from any exercise of HeartWare stock awards as described below, then appropriate adjustments to amounts payable in the merger will be made to account for such change.
 
Treatment of Options and Other Equity-Based Awards
 
The terms of the unvested and outstanding HeartWare incentive options will be adjusted to provide that, at the effective time of the merger, each unvested and outstanding HeartWare incentive option will be converted into an option to acquire, on the same terms and conditions as were applicable under such HeartWare incentive option, a number of shares of Thoratec common stock equal to the product of (i) the number of shares of HeartWare common stock represented by such HeartWare incentive option and (ii) 1.1499 rounded down, to the nearest whole share of Thoratec common stock and such new option to acquire Thoratec common stock will have an exercise price equal to (x) the per share exercise price specified in such unvested HeartWare incentive option divided by (y) 1.1499. The 1.1499 exchange ratio for each outstanding unvested HeartWare incentive option is subject to the same volume weighted average price adjustments to the stock portion of the merger consideration described in the section entitled, “— Merger Consideration” above. Any exercise price for a converted HeartWare incentive option that is measured in Australian dollars will be deemed to be converted to U.S. dollars at an exchange rate of 1.5265 Australian dollars for each U.S. dollar.
 
The terms of each outstanding vested HeartWare incentive option and each outstanding option to purchase shares of HeartWare common stock issued under the HeartWare employee stock option plan, will be adjusted to provide that, at or immediately prior to the effective time of the merger, each vested HeartWare incentive option and each HeartWare employee stock option, whether or not exercisable or vested, that is outstanding immediately prior to the effective time of the merger will be cancelled and will convert into the right to receive a cash payment, without interest, equal to (i) the excess, if any, of $30.19 over the applicable exercise price per share of HeartWare common stock of such cancelled option multiplied by (ii) the number of shares of HeartWare common stock such holder would have purchased (assuming full vesting of each outstanding option to purchase shares of HeartWare common stock issued under the HeartWare employee stock option plan) had such holder exercised such cancelled option in full immediately prior to the effective time. Any exercise price for an option to purchase shares of HeartWare common stock issued under the HeartWare employee stock option plan that is measured in Australian dollars will convert to U.S. dollars at an exchange rate of 1.5265 Australian dollars for each U.S. dollar.
 
The terms of each HeartWare stock-based award will be adjusted as necessary to provide that at, or immediately prior to, the effective time, each such HeartWare stock-based award, whether or not exercisable or vested, that is outstanding immediately prior to the effective time, will be cancelled and will convert into the right to receive a cash payment, without interest, equal to $30.19 multiplied by the number of shares of HeartWare


87


Table of Contents

common stock the holder of such HeartWare stock-based award would have received had such HeartWare stock-based award been fully earned, vested and exercisable and had been exercised or settled immediately prior to the effective time.
 
HeartWare will take any necessary action to ensure that, as of the effective time of the merger, the HeartWare International, Inc. 2008 Stock Incentive Plan, HeartWare International, Inc. Incentive Option Terms: Non-Executive Directors, HeartWare employee stock option plan, the HeartWare International, Inc. Restricted Stock Unit Plan and each other employee, director or consultant stock option, stock purchase or equity compensation plan, arrangement or agreement of HeartWare will terminate.
 
Exchange of Certificates
 
Prior to the effective time of the merger, Thoratec will appoint an exchange agent for the payment of merger consideration. At the effective time of the merger, Thoratec will deposit with the exchange agent certificates or, at Thoratec’s option, evidence of shares in book-entry form, representing shares of Thoratec stock and cash in an amount sufficient to pay the aggregate merger consideration. In addition, Thoratec will deposit with the exchange agent, as necessary from time to time after the effective time of the merger, any dividends or distributions with respect to shares of Thoratec stock constituting part of the merger consideration.
 
Surrender of Certificates
 
Promptly following the effective time of the merger, Thoratec has agreed to send HeartWare stockholders a letter of transmittal and instructions advising HeartWare stockholders how to surrender certificates in exchange for the merger consideration. The exchange agent will pay HeartWare stockholders their merger consideration after HeartWare stockholders have (i) surrendered their certificates to the exchange agent, or in the case of book-entry shares, followed the applicable procedures set forth in the letter of transmittal, and (ii) provided to the exchange agent a duly signed and completed letter of transmittal and any other items specified by the letter of transmittal. Interest will not be paid or accrue in respect of the merger consideration. The shares of Thoratec stock constituting part of the merger consideration, at Thoratec’s option, will be in uncertificated book-entry form, unless a physical certificate is requested by a HeartWare stockholder or otherwise required by applicable law.
 
Stock Transfer Books and Share Transfers
 
After the effective time of the merger, there will be no further transfers on the stock transfer books of HeartWare. If certificates are presented to the exchange agent or the intermediate surviving corporation or the surviving corporation for transfer, or transfer is sought for book-entry shares, such certificates or book-entry shares will be cancelled and exchanged as set forth under this heading “The Merger Agreement — Exchange of Certificates”.
 
Investment and Return of Exchange Fund
 
The exchange agent will invest the cash portion of the merger consideration deposited with the exchange agent as directed by Thoratec on a daily basis from time to time. Any interest or other income resulting from such investments will be paid to Thoratec. In the event such cash is insufficient to fully satisfy all of the payment obligations to be made by the exchange agent, Thoratec will promptly deposit cash with the exchange agent in an amount that is equal to the deficiency in the amount of cash required to fully satisfy such payment obligations.
 
Any shares of Thoratec common stock, cash dividends and other distributions deposited with the exchange agent (and any interest or other income earned thereon) that remains undistributed to the holders of certificates or book-entry shares six (6) months after the effective time of the merger will be delivered to Thoratec upon demand, and any HeartWare stockholders who have not complied with the exchange procedure will thereafter look only to Thoratec for payment of the merger consideration.
 
Lost Certificates
 
If a certificate for HeartWare common stock has been lost, stolen or destroyed, the exchange agent will issue the consideration payable under the merger agreement upon receipt of an affidavit from the applicable HeartWare stockholder of that fact and, if required by the exchange agent or Thoratec, the posting of a bond in an amount as the


88


Table of Contents

exchange agent or Thoratec reasonably directs as indemnity against any claim that may be made with respect to such certificate by the applicable HeartWare stockholder.
 
Dividends on Thoratec Common Stock
 
No dividends or other distributions with respect to shares of Thoratec common stock constituting part of the merger consideration, and no cash payment in lieu of fractional shares, will be paid to the holder of any certificates not surrendered or of any book-entry shares not transferred until such certificates or book-entry shares are surrendered or transferred in accordance with the exchange procedures.
 
Withholding
 
Thoratec, Merger Subsidiary, Merger Subsidiary Two, the surviving corporations and the exchange agent will be entitled to deduct and withhold from the consideration otherwise payable to any holder of shares of HeartWare stock, stock awards or otherwise pursuant to the merger agreement such amounts as may be required to be deducted and withheld with respect to the making of such payment under any federal, state, local or foreign tax law.
 
The Surviving Corporations
 
The Certificate of Incorporation of HeartWare will be amended and restated as of the effective time of the merger, and, as so amended, will be the Certificate of Incorporation of the intermediate surviving corporation, as set forth on Exhibit A to the merger agreement, a copy of which has been attached as Annex A to this proxy statement/prospectus. Following the merger, if the value of the stock consideration is at least 41% of the aggregate merger consideration at closing, the Certificate of Incorporation of Merger Subsidiary Two shall be amended and restated and, as so amended, shall be the Certificate of Incorporation of the surviving corporation. The bylaws of the intermediate surviving corporation shall be amended and restated as of the effective time of the merger to be identical to the bylaws of Merger Subsidiary as in effect immediately prior to the effective time of the merger. If the value of the stock consideration is at least 41% of the aggregate merger consideration at the effective time of the merger, the bylaws of the surviving corporation shall be amended and restated to be identical to the bylaws of the intermediate surviving corporation.
 
After the effective time of the merger, until successors are duly elected or appointed, the directors of Merger Subsidiary shall be the directors of the intermediate surviving corporation and the officers of Merger Subsidiary shall be the officers of the intermediate surviving corporation. If the value of the stock consideration is at least 41% of the aggregate merger consideration at the effective time of the merger, after the second merger effective time, until successors are duly elected or appointed and qualified, the directors of the intermediate surviving corporation shall be the directors of the surviving corporation and the officers of the intermediate surviving corporation shall be the officers of the surviving corporation.
 
Representations and Warranties
 
The merger agreement contains representations and warranties made by HeartWare to Thoratec and representations and warranties made by Thoratec to HeartWare. The assertions embodied in those representations and warranties were made solely for purposes of the merger agreement and may be subject to important qualifications and limitations agreed by the parties in connection with negotiating its terms. Moreover, some of those representations and warranties may not be accurate or complete as of any particular date because they are subject to a contractual standard of materiality or material adverse effect different from that generally applicable to public disclosures to stockholders or used for the purpose of allocating risk between the parties to the merger agreement rather than establishing matters of fact. For the foregoing reasons, you should not rely on the representations and warranties contained in the merger agreement as statements of factual information. None of the representations and warranties of the parties to the merger agreement will survive the effective time of the merger.

Many of HeartWare’s and Thoratec’s representations and warranties are qualified by a material adverse effect standard. For purposes of the merger agreement, “material adverse effect” for HeartWare is defined to mean any event, change or occurrence which, individually or together with any one or more other events, changes or occurrences (A) has had, or is reasonably likely to have, a material adverse effect upon the business, assets, liabilities, condition (financial or otherwise) or operating results of HeartWare and its subsidiaries taken as a whole; provided, that in no event shall any of the following events, changes or occurrences constitute a HeartWare material adverse effect or be considered in determining whether a HeartWare material adverse effect has occurred or is reasonably likely to occur: (i) changes in general economic, securities market or business conditions except to the extent that such changes have a materially disproportionate effect (relative to other industry participants) on HeartWare and its subsidiaries, taken as a whole, (ii) changes in conditions generally affecting the industry in which HeartWare and its subsidiaries operate, except to the extent that such changes have a materially disproportionate effect (relative to other industry participants that are development stage companies at a similar stage of development as HeartWare and its subsidiaries) on HeartWare and its subsidiaries, taken as a whole, (iii) any change in the trading price or trading volume of HeartWare common stock or HeartWare CDIs in and of itself or any failure to meet internal or published projections or forecasts for any period in and of itself (in each case, as distinguished from any event, change or occurrence giving rise or contributing to such change or failure), (iv) changes in GAAP, or applicable laws or (v) changes resulting from the announcement or the existence of, or that result from the compliance by HeartWare with its obligations under, the merger agreement, or (B) would prevent HeartWare from consummating, or materially delay, the merger.
 
“Material adverse effect” for Thoratec is defined to mean any event, change or occurrence which, individually or together with any one or more other events, changes or occurrences (A) has had, or is reasonably likely to have, a material adverse effect upon the business, assets, liabilities, condition (financial or otherwise) or operating results of Thoratec and its subsidiaries taken as a whole; provided, that in no event shall any of the following events, changes or occurrences constitute a Thoratec material adverse effect or be considered in determining whether a Thoratec material adverse effect has occurred or is reasonably likely to occur: (i) changes in general economic, securities market or business conditions except to the extent that such changes have a materially disproportionate effect (relative to other industry participants) on Thoratec and its subsidiaries, taken as a whole, (ii) changes in conditions generally affecting the industry in which Thoratec and its subsidiaries operate, except to the extent that such changes have a materially disproportionate effect (relative to other industry participants that are at a similar stage of development as Thoratec and its subsidiaries) on Thoratec and its subsidiaries, taken as a whole, (iii) any change in the trading price or trading volume of Thoratec common stock in and of itself or any failure to meet internal or published projections or forecasts for any period in and of itself (in each case, as distinguished from any event, change or occurrence giving rise or contributing to such change or failure), (iv) changes in GAAP or applicable laws or (v) changes resulting from the announcement or the existence of, or that result from the compliance by Thoratec with its obligations under, the merger agreement or (B) would prevent Thoratec, Merger Subsidiary or Merger Subsidiary Two from consummating, or materially delay, the merger.

Stockholder Meeting
 
Unless the merger agreement has been terminated, HeartWare will establish a record date for, duly call, give notice of, convene and hold a meeting of the HeartWare stockholders for the purpose of obtaining the stockholder approval of the merger, on or prior to the earlier of (i) forty-five (45) days after the applicable waiting period (including any extensions thereof) under the HSR Act expires or is terminated and (ii) October 15, 2009 (or, if this registration statement has not become effective by the earlier of such dates, within forty-five (45) days after such date on which this registration statement becomes effective). Unless the merger agreement has been terminated, HeartWare will use its commercially reasonable efforts to obtain the approval of the HeartWare stockholders and comply with all legal requirements applicable to the stockholder meeting. Provided the merger agreement has not been terminated as set forth under the heading “The Merger Agreement — Termination” below, HeartWare’s obligations set forth under this heading “The Merger Agreement — Stockholder Meeting” will not be affected by any public announcement or disclosure of, or the communication to HeartWare of, any Acquisition Proposal, as defined below, under the heading “The Merger Agreement — Agreement Not to Solicit Other Offers” or by HeartWare’s failure to make or HeartWare’s withdrawal or modifications in a manner adverse to Thoratec, a recommendation that the HeartWare stockholders vote for the adoption of the merger agreement, or public recommendation of any Acquisition Proposal (as defined below) or public action inconsistent with the recommendation of the merger agreement.
 
Agreement Not to Solicit Other Offers
 
HeartWare has agreed that it, its subsidiaries and their officers, directors, employees and other agents and advisors will not, directly or indirectly:
 
  •  solicit, initiate or knowingly take any action to facilitate or encourage any inquiries regarding, or the making or submission of any proposal or offer that constitutes, or could be reasonably expected to result in, an Acquisition Proposal, as defined under this heading, below;
 
  •  enter into or participate in any discussions or negotiations regarding any Acquisition Proposal, or furnish or disclose any information relating to HeartWare or any of its subsidiaries or knowingly cooperate in any way with, or knowingly take any action to facilitate or encourage any effort by, any third-party that is seeking to make, or has made, any Acquisition Proposal;
 
  •  fail to make, withdraw or modify in a manner adverse to Thoratec, the HeartWare board of directors’ recommendation that the HeartWare stockholders vote in favor of the adoption of the merger agreement (or publicly recommend any Acquisition Proposal or take any public action or make any public statement inconsistent with the recommendation of the merger agreement); or
 
  •  enter into any agreement, agreement in principle, letter of intent or other similar instrument relating to any Acquisition Proposal.
 
However, prior to obtaining the approval of the HeartWare stockholders in favor of the adoption of the merger agreement and in response to a written Acquisition Proposal received by HeartWare that was not solicited in violation of the terms described in the bullet points above in “The Merger Agreement — Agreement Not to Solicit Other Offers”, HeartWare may provide access to its properties, contracts, personnel, books and records and furnish information, data and/or draft agreements with respect to HeartWare and its subsidiaries to the person making such Acquisition Proposal and its representatives and participate in discussions or negotiations with the person making such Acquisition Proposal and its representatives regarding such Acquisition Proposal, if the HeartWare board of directors has first determined in good faith (after consultation with its outside legal counsel and financial advisors) that such Acquisition Proposal constitutes, or could reasonably be expected to lead to a Superior Proposal, as such term is defined below, and that its failure to take such action would reasonably be expected to be inconsistent with the fiduciary duties of the HeartWare board of directors. In the event that the HeartWare board of directors determines in good faith (after consultation with its outside legal counsel and financial advisors) that such


94


Table of Contents

Acquisition Proposal constitutes a Superior Proposal, the HeartWare board of directors may fail to make, withdraw or modify in a manner adverse to Thoratec, a recommendation that the HeartWare stockholders vote in favor of the adoption of the merger agreement (or publicly recommend any Acquisition Proposal or take any public action or make any public statement inconsistent with the recommendation of the merger agreement).
 
The HeartWare board of directors may not fail to make, withdraw or modify in a manner adverse to Thoratec, a recommendation that the HeartWare stockholders vote in favor of the adoption of the merger agreement (or publicly recommend any Acquisition Proposal or take any public action or make any public statement inconsistent with the recommendation of the merger agreement) or enter into an agreement with respect to a Superior Proposal unless:
 
  •  HeartWare has given Thoratec three (3) business days written notice of its intention to take such action (it being understood and agreed that, in connection with a Superior Proposal, any change to the consideration offered or other material terms of any Superior Proposal shall require an additional notice to Parent and a new two (2) business day notice period);
 
  •  the HeartWare board of directors has considered in good faith (after consultation with its outside legal counsel and financial advisors) any changes or revisions to the merger agreement proposed by Thoratec and (i) has not determined that the Superior Proposal would no longer constitute a Superior Proposal if such changes were to be given effect or (ii) has determined to withdraw or modify its recommendation in a manner adverse to Thoratec even if such changes were to be given effect; and
 
  •  HeartWare has complied with its obligations under this heading “The Merger Agreement — Agreement Not to Solicit Other Offers” and in the event that the HeartWare board of directors has determined to enter into an agreement regarding such Superior Proposal, HeartWare has terminated the merger agreement and paid to Thoratec any termination fee as described under the heading “The Merger Agreement — Termination Fee”.
 
HeartWare has agreed to:
 
  •  promptly (and in any event within two (2) business days) notify Thoratec orally and in writing of the receipt of any Acquisition Proposal or any indication in writing that a third-party may be considering making an Acquisition Proposal, along with the identity of the person making such Acquisition Proposal, and to the extent applicable, provide Thoratec with a copy or written summary of the material terms of such Acquisition Proposal;
 
  •  keep Thoratec reasonably informed of the status on a current basis (including any change to the material terms) of any such Acquisition Proposal, potential Acquisition Proposal or information request;
 
  •  following any determination by the HeartWare board of directors that an Acquisition Proposal constitutes a Superior Proposal, deliver to Thoratec a written notice advising it that the HeartWare board of directors has made such determination together with a copy of any written summary or any draft or definitive agreements related to such Superior Proposal and a summary of the material terms of such Superior Proposal;
 
  •  prior to furnishing any information to or entering into discussions or negotiations with any person making an Acquisition Proposal, receive from such person an executed confidentiality agreement, the terms of which shall be no less favorable to HeartWare than, in the aggregate, those contained in the confidentiality agreement dated as of November 14, 2008 by and between HeartWare and Thoratec, which we refer to as the confidentiality agreement; and
 
  •  promptly provide to Thoratec any non-public information concerning HeartWare or any of its subsidiaries not previously provided to Thoratec or representatives of Thoratec that is provided to any person making an Acquisition Proposal.
 
HeartWare has also agreed that neither it nor any of its subsidiaries will terminate, waive, amend or modify any provision or any existing standstill or confidentiality agreement to which it or any of its subsidiaries is a party, or enter into any confidentiality agreement that contains a standstill provision that is less favorable to HeartWare than the standstill provision contained in the confidentiality agreement (or that does not include any standstill provision), unless the failure to take such action by the HeartWare board of directors would be reasonably expected to be inconsistent with its fiduciary duties under applicable law (in which case, such termination, waiver, amendment or


95


Table of Contents

modification, or the terms of any standstill provision contained in any confidentiality agreement entered into pursuant to the terms of the merger agreement that is less favorable to HeartWare than the standstill provision contained in the confidentiality agreement (or the absence of any such standstill provision), shall also apply to the confidentiality agreement, to the extent applicable).
 
As used in the merger agreement, other than as described under the heading “The Merger Agreement — Termination Fee,” the term “Acquisition Proposal” means, other than the transactions contemplated by the merger agreement, any offer or proposal from any third-party relating to, whether in a single transaction or series of transactions:
 
  •  any acquisition or purchase, direct or indirect, of 20% or more of the assets (based on fair market value) of HeartWare and its subsidiaries, taken as a whole, or over 20% of any class of equity or voting securities of HeartWare or of any of its subsidiaries;
 
  •  any tender offer (including a self-tender offer) or exchange offer that, if consummated, would result in a third-party beneficially owning 20% or more of any class of equity or voting securities of HeartWare or of any of its subsidiaries; or
 
  •  a merger, consolidation, share exchange, business combination, sale of substantially all the assets, reorganization, recapitalization, liquidation, dissolution or other similar transaction involving HeartWare or any of its subsidiaries whose assets, individually or in the aggregate, constitute more than 20% of the assets (based on fair market value) of HeartWare and its subsidiaries, taken as a whole.
 
As used in the merger agreement, the term “Superior Proposal” means any bona fide, unsolicited written offer or proposal from any third-party relating to, whether in a single transaction or series of transactions:
 
  •  any acquisition or purchase, direct or indirect, of 50% or more of the assets (based on fair market value) of HeartWare and its subsidiaries, taken as a whole, or over 50% of any class of equity or voting securities of HeartWare or of any of its subsidiaries;
 
  •  any tender offer (including a self-tender offer) or exchange offer that, if consummated, would result in a third-party’s beneficially owning 50% or more of any class of equity or voting securities of HeartWare or of any of its subsidiaries; or
 
  •  a merger, consolidation, share exchange, business combination, sale of substantially all the assets, reorganization, recapitalization, liquidation, dissolution or other similar transaction involving HeartWare or any of its subsidiaries whose assets, individually or in the aggregate, constitute more than 50% of the assets (based on fair market value) of HeartWare and its subsidiaries, taken as a whole,
 
in each case in which the HeartWare board of directors determines in good faith (after consultation with outside legal counsel and financial advisors) that such offer or proposal (i) is reasonably likely to be consummated and (ii) if consummated, would result in a transaction more favorable to HeartWare’s stockholders than the transactions provided for in the merger agreement (including any adjustment to the terms and conditions of the merger agreement proposed by Thoratec in response to such offer or proposal), and in each case taking into account all of the terms and conditions of such offer or proposal, including the third-party making such offer or proposal and the legal, financial, regulatory and other aspects of such offer or proposal, including any conditions relating to financing, regulatory approvals or other events or circumstances.
 
Efforts to Complete the Merger
 
Subject to the terms and conditions of the merger agreement, each of the parties has agreed to use its reasonable best efforts to take all actions, and to assist and cooperate with the other party in doing, all things necessary, proper or advisable under applicable law to make effective the mergers and the other transactions contemplated in the merger agreement. Without limiting the generality of the foregoing, each party has agreed to use its reasonable best efforts to (i) prepare and file as soon as practicable all forms, registrations and notices relating to antitrust, competition, trade or other regulatory matters that are required by applicable law to be filed in order to consummate the merger and the other transactions contemplated in the merger agreement, and take such actions as are reasonably necessary to obtain any requisite approvals, consents, exemptions or waivers by, or to avoid an action by, any

Notwithstanding the foregoing, each party hereto agrees that the reasonable best efforts of any party shall not require any party or its affiliates or subsidiaries to: (i) agree to or effect any divestiture or hold-separate order, or enter into any license or similar agreement with respect to, or agree to restrict its ownership or operation of, any business or assets of any party or any of its affiliates or subsidiaries, (ii) enter into, amend, or agree to enter into or amend, any contracts of any party or any of its affiliates or subsidiaries or (iii) otherwise waive, abandon or alter any material rights or obligations of any party or any of its subsidiaries or affiliates.

For a period of twelve (12) months following the effective time of the merger, HeartWare employees who remain in the employment of the surviving corporation or the intermediate surviving corporation will receive employee benefits that, in the aggregate, are substantially similar to those received by similarly situated employees of Thoratec, provided that neither Thoratec nor either surviving corporation shall have any obligation to issue, or adopt any plans or arrangements providing for the issuance of, shares of capital stock, warrants, options, stock appreciation rights or other rights in respect of any shares of capital stock of any entity or any securities convertible or exchangeable into such shares pursuant to any such plans or arrangements.
 
Prior to the date of the merger agreement, HeartWare entered into retention bonus agreements in the form attached as Exhibit B to the merger agreement, a copy of which has been attached as Annex A to this proxy statement/prospectus, for the benefit of certain HeartWare employees pursuant to which such employees will receive cash payments in the amounts, at the times and on the conditions set forth in the retention bonus agreements. With the prior written notice of the names of the employees and the amounts and terms of the retention bonuses to Thoratec, and with prior consultation with Thoratec, HeartWare will also be permitted to award additional cash retention bonuses to other HeartWare employees, payable on or following the effective time of the merger. The maximum aggregate amount payable (inclusive of any and all payments, reimbursements and tax gross-ups) pursuant to such bonuses and retention bonus agreements will be $8.0 million.
 
Upon Thoratec’s request at least five (5) business days prior to the effective time of the merger, HeartWare shall take all actions required to terminate its 401(k) plan prior to the effective time of the merger.
 
Indemnification and Insurance
 
The certificate of incorporation and bylaws of the surviving corporation will contain provisions no less favorable with respect to indemnification than those set forth in the certificate of incorporation and bylaws of HeartWare, which provisions shall not be amended, repealed or otherwise modified for a period of seven (7) years from the effective time of the merger in any manner that would adversely affect the rights thereunder. The merger agreement provides that for a period of seven (7) years following the merger, Thoratec will provide director’s and officer’s liability insurance for the present and former directors and officers of HeartWare with respect to claims arising from facts or events occurring before the merger is completed, provided Thoratec is not obligated to pay an aggregate premium in excess of 250% of the amount per annum HeartWare paid in its last full fiscal year. This directors’ and officers’ liability insurance will contain at least the same coverage and amounts, and terms and conditions no less advantageous, as HeartWare’s existing coverage. Alternatively, the merger agreement provides that Thoratec may purchase a seven (7) year prepaid policy on terms no less favorable than those in HeartWare’s current director’s and officer’s liability insurance policy maintained and in effect, provided, however, that the cost of such policy does not exceed 250% of the annual premium currently paid by HeartWare.

Frustration of Closing Conditions
 
No party to the merger agreement may rely on the failure of any condition to closing to be satisfied if such failure was caused by the failure of such party to comply with its obligations set forth in the merger agreement.

  •  upon mutual written agreement of HeartWare and Thoratec;
 
  •  if the merger is not consummated by July 31, 2009; provided, however, that if (i) all closing conditions have been satisfied or properly waived other than those not capable of being satisfied until the effective time of the merger, approval of the merger agreement by HeartWare stockholders and the expiration or termination of the applicable waiting period under the HSR Act, and (ii) the HeartWare or the Thoratec board of directors determines, in good faith, that it is reasonably likely that expiration or termination of the applicable waiting period under the HSR Act can occur before October 31, 2009, then either HeartWare or Thoratec may, at its option, extend the deadline of July 31, 2009 to October 31, 2009; further, in the event that (i) the deadline has been so extended to October 31, 2009, (ii) all closing conditions have been satisfied other than the expiration or termination of the applicable waiting period under the HSR Act, (iii) the Thoratec board of directors determines, in good faith and after consultation with outside legal counsel, that it is reasonably likely that expiration or termination of the applicable waiting period can occur before January 31, 2010, and (iv) prior to or concurrently with such extension, Thoratec funds $8.0 million into the escrow account as described below under the heading “The Loan Agreement — The Loans” beginning on page 103, then Thoratec may extend the deadline from October 31, 2009 to January 31, 2010;
 
  •  if any applicable law prohibits or makes consummation of the merger illegal, or enjoins the consummation of the merger and such injunction is final or nonappealable; or

  incapable of being cured prior to the earlier of (i) the merger agreement deadline described in the second bullet point in the first paragraph of the section entitled “The Merger Agreement — Termination” above and (ii) twenty (20) business days after Thoratec receives written notice of such breach from HeartWare;
 
  •  prior to the HeartWare stockholders’ adoption of the merger agreement, (i) the HeartWare board of directors has received a Superior Proposal and has determined in good faith that the failure to accept such Superior Proposal would reasonably be expected to be inconsistent with its fiduciary duties, (ii) HeartWare has complied in all materials respects with the provisions described under the heading “The Merger Agreement — Agreement Not to Solicit Other Offers” above and (iii) HeartWare has paid any termination fee to Thoratec as described under the heading “The Merger Agreement — Termination Fee” below; or
 
  •  the volume weighted average of the per share closing prices of Thoratec common stock on The NASDAQ Stock Market for the twenty (20) consecutive trading days ending on and including the fifth (5th) trading day prior to, but not including, the closing date is less than or equal to $18.38, or 70% of $26.25, the Thoratec price used to determine the merger consideration, and after HeartWare has delivered to Thoratec a notice to terminate, Thoratec does not timely provide notice of its intent to increase the number of shares of Thoratec common stock payable in the merger such that the value of the stock portion of the merger consideration at closing is equal to 70% of the value of the aggregate Thoratec stock consideration payable in the merger (calculated using the $26.25 price per share of Thoratec common stock used to determine the stock portion of the merger consideration).
 
Effect of Termination
 
If the merger agreement is terminated, it will become void and have no effect, and there will be no liability on the part of HeartWare and Thoratec, Merger Subsidiary or Merger Subsidiary Two, except that (i) HeartWare, Thoratec and their respective subsidiaries will remain liable for any knowing, intentional and material breach of the merger agreement, and (ii) designated provisions of the merger agreement will survive termination, including, but not limited to, the confidential treatment of information and publicity restrictions.
 
Termination Fee
 
HeartWare has agreed to pay a termination fee of $11.3 million to Thoratec under the following circumstances:
 
  •  if the merger agreement is terminated by HeartWare prior to the HeartWare stockholders’ adoption of the merger agreement as a result of the HeartWare board of directors’ receipt of a Superior Proposal and its good faith determination that the failure to accept such Superior Proposal would reasonably be expected to be inconsistent with its fiduciary duties and HeartWare has complied in all material respects with the obligations described under the heading “The Merger Agreement — Agreement Not to Solicit Other Offers” above;

HeartWare will pay a termination fee of $5.0 million to Thoratec under the following circumstances:
 
  •  if the merger agreement is terminated by Thoratec as a result of the HeartWare board of directors, other than in connection with a Superior Proposal, failing to make, withdrawing or modifying in a manner adverse to Thoratec, a recommendation that the HeartWare stockholders vote for the adoption of the merger agreement or HeartWare taking any public action inconsistent with the recommendation of the merger agreement.
 
If the merger agreement is terminated by Thoratec as a result of the HeartWare board of directors, other than in connection with a Superior Proposal, failing to make, withdrawing or modifying in a manner adverse to Thoratec, a recommendation that the HeartWare stockholders vote for the adoption of the merger agreement or HeartWare taking any public action inconsistent with the recommendation of the merger agreement, and within twelve (12) months of such termination, HeartWare enters into a definitive agreement with respect to an Acquisition Proposal or any Acquisition Proposal is consummated, then HeartWare will pay to Thoratec a fee of $6.3 million, with such fee payment to be made upon the earlier to occur of the execution of a definitive agreement relating to, or consummation of, such Acquisition Proposal.
 
As used under this heading “The Merger Agreement — Termination Fee”, the term “Acquisition Proposal” means, other than the transactions contemplated by the merger agreement, any offer or proposal from any third-party relating to, whether in a single transaction or series of transactions:
 
  •  any acquisition or purchase, direct or indirect, of 50% or more of the assets (based on fair market value) of HeartWare and its subsidiaries, taken as a whole, or over 50% of any class of equity or voting securities of HeartWare or of any of its subsidiaries;

  •  a merger, consolidation, share exchange, business combination, sale of substantially all the assets, reorganization, recapitalization, liquidation, dissolution or other similar transaction involving HeartWare or any of its subsidiaries whose assets, individually or in the aggregate, constitute more than 50% of the assets (based on fair market value) of HeartWare and its subsidiaries, taken as a whole.
 
Amendments and Waivers
 
The merger agreement may be amended prior to the effective time of the merger if such amendment is in writing and is signed by each party to the merger agreement. However, after adoption of the merger agreement by the HeartWare stockholders, no amendment that, by applicable law or in accordance with the rules of any relevant stock exchange, requires further approval by such stockholders may be made without such stockholder approval.
 
At any time prior to the effective time of the merger, HeartWare, Thoratec, Merger Subsidiary or Merger Subsidiary Two may, to the extent permitted by applicable law:
 
  •  extend the time for the performance of any of the obligations or other acts of the other parties under the merger agreement;
 
  •  waive any inaccuracies in the representations and warranties of the other parties contained herein or in any instrument delivered pursuant hereto; or


102


Table of Contents

 
  •  waive compliance with any of the covenants or agreements of the other parties or conditions to the obligations of the waiving parties contained herein.
 
However, after adoption of the merger agreement by HeartWare stockholders, no extension or waiver that, by applicable law or in accordance with the rules of any relevant stock exchange, requires further approval by such stockholders may be made without such stockholder approval.
 
THE LOAN AGREEMENT
 
This section of the proxy statement/prospectus describes the material provisions of the loan agreement but does not purport to describe all of the terms of the loan agreement. The following summary is qualified in its entirety by reference to the complete text of the loan agreement, which is attached as Annex B to this proxy statement/prospectus. We urge you to read the full text of the loan agreement because it is the legal document that governs the loans from Thoratec to HeartWare in connection with the merger. The loan agreement and the discussion under the heading “The Loan Agreement” have been included to provide you with information regarding the terms of the loan agreement. They are not intended to provide any other factual information about HeartWare and Thoratec. That information can be found elsewhere in this proxy statement/prospectus and in the other public filings made by HeartWare or Thoratec with the SEC, which are available without charge at www.sec.gov. See “Where You Can Find More Information” beginning on page 127 of this proxy statement/prospectus.
 
The loan agreement contains representations and warranties the parties made to each other as of specific dates. The assertions embodied in those representations and warranties were made solely for purposes of the contract between HeartWare and Thoratec and may be subject to important qualifications and limitations agreed by HeartWare and Thoratec in connection with negotiating its terms. Moreover, certain representations and warranties may not be accurate or complete as of any specified date because they are subject to a contractual standard of materiality different from those generally applicable to stockholders or were used for the purpose of allocating risk between HeartWare and Thoratec rather than establishing matters as facts. For the foregoing reasons, you should not rely on the representations and warranties as statements of factual information.
 
The Loans
 
Concurrent with the execution and delivery of the merger agreement, Thoratec entered into the loan agreement with HeartWare and all of HeartWare’s subsidiaries, as guarantors, pursuant to which Thoratec agreed to deposit up to an aggregate of $28.0 million into an escrow account and to loan such funds through one or more term loans to HeartWare, subject to the terms and conditions set forth in the loan agreement, in order to fund the ongoing operations of HeartWare through the closing of the merger.
 
Thoratec has agreed to make one or more term loans to HeartWare from and after February 12, 2009 but no later than the earlier of (i) November 1, 2011, (ii) the date on which all outstanding principal amount of loans to HeartWare, including any accrued and unpaid interest, as well as any amounts remaining in the escrow account that have not been loaned to HeartWare, are converted into shares of HeartWare common stock as described below under the heading “The Loan Agreement — Conversion of Loans”, or (iii) the date on which the outstanding principal amount of the loans becomes due and payable in full, whether by acceleration or otherwise, which we refer to as the Maturity Date. Thoratec deposited $20.0 million into the escrow account on February 13, 2009, although HeartWare could not borrow any funds prior to May 1, 2009. Beginning as of May 1, 2009, HeartWare may borrow up to an aggregate of $12.0 million and beginning on July 31, 2009, HeartWare may borrow up to an aggregate of $20.0 million. In the event that all of the conditions to closing the merger (other than those conditions that, by their terms, are not capable of being satisfied until the closing, and the condition that relates to the expiration or termination of the applicable waiting period under the HSR Act), have been satisfied and Thoratec exercises an option under the merger agreement to extend the outside date for the completion of the merger from October 31, 2009 until January 31, 2010 as described under the heading “The Merger Agreement — Termination” beginning on page 100, then HeartWare may borrow up to an additional $8.0 million, which Thoratec must deposit into the escrow account at the time it exercises its extension option. HeartWare may borrow the additional $8.0 million on or after the date Thoratec exercises such option but no later than the Maturity Date.


103


Table of Contents

Interest
 
The loans will bear interest at a rate per annum equal to 10%. Interest on each loan will be payable in arrears on (i) March 31, June 30, September 30 and December 31 of each year, commencing on March 31, 2009, (ii) the Maturity Date, (iii) the date of repayment or prepayment made in respect thereof and (iv) the date of conversion of such loan as described under the heading “The Loan Agreement — Conversion of the Loans” below.
 
Upon the occurrence and continuance of an event of default, as described below under the heading “The Loan Agreement — Events of Default”, HeartWare will, on demand from time to time, pay interest in cash, to the extent permitted by law, on such defaulted amount to but excluding the date of actual payment at a rate equal to 12% per annum.
 
Repayment and Prepayment of Loans
 
All loans then outstanding will be due and payable in full in cash on the Maturity Date, together with accrued and unpaid interest on the principal amount to be paid to but excluding the date of payment.
 
HeartWare may, at any time and from time to time, prepay the loans in whole or in part upon at least five (5) business days prior irrevocable written notice to Thoratec. Any partial prepayment must be in a minimum amount of $500,000 and integral multiples of $250,000 in excess thereof. However, HeartWare may not voluntarily prepay the loans prior to the date, if any, upon which the merger agreement is terminated, or at any time prior to the consummation of a change of control of HeartWare, if a termination of the merger agreement has occurred as a result of a Superior Proposal, as such term is defined under the heading “The Merger Agreement — Agreement Not to Solicit Other Offers” beginning on page 94.
 
Upon a change of control of HeartWare, HeartWare will repay all or any part of the loans at 100% of the outstanding principal amount of the loans plus accrued and unpaid interest to the date of repayment.
 
Conversion of Loans
 
In the event that the merger agreement is terminated, Thoratec may convert the outstanding principal amount of the loans to HeartWare, including any accrued and unpaid interest, as well as any amounts remaining in the escrow account that have not been loaned to HeartWare, in whole or in part, into shares of HeartWare common stock based on a conversion rate equal to (i) $35.00 Australian dollars per share of HeartWare common stock or (ii) $21.5355 per share of HeartWare common stock in the event the mergers are not consummated as a result of a termination due to a competing Acquisition Proposal that the HeartWare board of directors determines is a Superior Proposal in accordance with the terms of the merger agreement. The conversion rate will be adjusted in the event of any stock split, dividend, distribution or other subdivision or other reclassification of HeartWare common stock. With respect to any conversion of any convertible portion of the loans or escrow funds into HeartWare common stock that would be subject to a waiting period provided by the HSR Act, no such conversion will be considered effective until the expiration or termination of such waiting period.
 
Notwithstanding the foregoing, for so long as HeartWare CDIs are listed on ASX, no more than 14.99% in the aggregate of the then authorized and outstanding shares of HeartWare common stock as of the date of any conversion will be issued to Thoratec.
 
Representations and Warranties
 
The loan agreement contains representations and warranties made by HeartWare and its subsidiaries to Thoratec and representations and warranties made by Thoratec to HeartWare and its subsidiaries. The assertions embodied in those representations and warranties were made solely for purposes of the loan agreement and may be subject to important qualifications and limitations agreed by the parties in connection with negotiating its terms. Moreover, some of those representations and warranties may not be accurate or complete as of any particular date because they are subject to a contractual standard of materiality or material adverse effect different from that generally applicable to public disclosures to stockholders or used for the purpose of allocating risk between the parties to the loan agreement rather than establishing matters of fact. For the foregoing reasons, you should not rely on the representations and warranties contained in the loan agreement as statements of factual information.

THE INVESTOR’S RIGHTS AGREEMENT
 
This section of the proxy statement/prospectus describes the material provisions of the investor’s rights agreement but does not purport to describe all of the terms of the investor’s rights agreement. The following summary is qualified in its entirety by reference to the complete text of the investor’s rights agreement, which is attached as Annex C to this proxy statement/prospectus. We urge you to read the full text of the investor’s rights agreement because it is the legal document that governs the registration rights of Thoratec from HeartWare in connection with the merger. The investor’s rights agreement and the discussion under the heading “The Investor’s Rights Agreement” have been included to provide you with information regarding the terms of the investor’s rights agreement. They are not intended to provide any other factual information about HeartWare and Thoratec. That information can be found elsewhere in this proxy statement/prospectus and in the other public filings made by HeartWare or Thoratec with the SEC, which are available without charge at www.sec.gov. See “Where You Can Find More Information” beginning on page 127 of this proxy statement/prospectus.
 
Concurrent with the execution of the loan agreement, HeartWare and Thoratec entered into the investor’s rights agreement. Pursuant to the investor’s rights agreement, HeartWare has agreed to provide certain registration rights with respect to any HeartWare common stock issued upon the conversion of the loans or any amounts held in the escrow account as described under the heading “The Loan Agreement — Conversion of Loans” beginning on page 104.
 
Demand Registration
 
If HeartWare receives at any time after any termination of the merger agreement a written request from Thoratec to file a Form S-3 shelf registration statement covering the registration of any and all of HeartWare common stock issued or issuable from time to time upon conversion of the convertible loans as described under the heading “The Loan Agreement — Conversion of Loans” beginning on page 104 and any HeartWare common stock issued or issuable in respect of such HeartWare common stock upon any stock split, stock dividend, recapitalization, reclassification, merger, consolidation or other similar event, which we refer to as the Registrable Securities, HeartWare will use commercially reasonable efforts to file, within thirty (30) days after the receipt of such request, a registration statement on Form S-3 and will use its commercially reasonable efforts to cause such shelf registration statement to be declared effective by the SEC as soon as reasonably practicable after the filing thereof.
 
Upon the filing of such shelf registration statement, HeartWare will use its commercially reasonable efforts to keep such shelf registration statement effective with the SEC for nine (9) months following the date of the initial effectiveness of the shelf registration statement, as such period may be extended pursuant to the terms of the investor’s rights agreement.
 
Piggyback Registration
 
Whenever HeartWare proposes to register any of its common stock in connection with an underwritten public offering of such securities solely for cash, other than a registration on Form S-4 or Form S-8, and the registration form to be filed may be used for the registration or qualification for distribution of Registrable Securities by HeartWare, HeartWare will give prompt notice to Thoratec of its intention to effect such registration (but in no event less than ten (10) business days prior to the anticipated filing date) and will include in such registration all Registrable Securities with respect to which HeartWare has received written requests for inclusion from Thoratec within ten (10) business days after the date of HeartWare’s notice. However, if the managing underwriter in any underwritten offering pursuant to such registration statement advises HeartWare that the number of securities requested to be included in such registration exceeds the number which can be sold without adversely affecting the marketability of the offering, HeartWare will include in such registration only such number of securities that in the opinion of such underwriter can be sold without adversely affecting the marketability of the offering, which securities will be so included in the following order of priority:
 
  •  first, the securities HeartWare proposes to sell; and
 
  •  second, the Registrable Securities of Thoratec and any other securities of HeartWare that have been requested by other holders of HeartWare common stock having registration rights to be so included, on a pro


108

  rata basis, up to the maximum number of securities the managing underwriter advises HeartWare may be sold without adversely affecting the marketability of such offering.
 
Thoratec may withdraw its Registrable Securities from such registration statement by giving prompt written notice to HeartWare and any managing underwriter on or before the fifth (5th) business day prior to the planned effective date of such registration statement. HeartWare may terminate or withdraw any such registration statement prior to the effectiveness of such registration statement, whether or not Thoratec has elected to include Registrable Securities in such registration.
 
Registration Expenses
 
All registration, filing fees, fees and expenses of compliance with securities or blue sky laws and certain other associated expenses incidental to HeartWare’s compliance with the investor’s rights agreement will be paid by HeartWare. Thoratec will pay all underwriting discounts, selling commissions and transfer taxes applicable to the sale of Registrable Securities by Thoratec and any other registration expenses required by law to be paid by Thoratec; provided, however, that in the event of a registration statement of Registrable Securities as described under the heading “The Investor’s Rights Agreement — Piggyback Registration” above, such underwriting discounts, selling commissions and transfer taxes shall be payable by HeartWare and the holders of securities listed in such registration statement pro rata on the basis of the amount of proceeds received from the sale of such securities so registered and sold in such sale.
 
THE SUPPORT AGREEMENTS
 
This section of the proxy statement/prospectus describes the material provisions of the support agreements entered into by Thoratec with each of the directors (except one) and certain officers of HeartWare, which we refer to each as a management support agreement, and with Apple Tree Partners, a beneficial owner of approximately 30.2% of HeartWare common stock, which we refer to as the stockholder support agreement. We refer to the management support agreement and stockholder support agreement collectively as the support agreements. The summary of the support agreements does not purport to describe all of the terms of the support agreements. The following summary is qualified in its entirety by reference to the complete text of the management support agreement and the stockholder support agreement, which are attached as Annexes D and E, respectively, to this proxy statement/prospectus. We urge you to read the full text of the support agreements because they are the legal documents that govern the voting obligations of certain HeartWare stockholders in connection with the merger. The support agreements and the discussion under the heading “The Support Agreements” have been included to provide you with information regarding the terms of the support agreements. They are not intended to provide any other factual information about HeartWare and Thoratec. That information can be found elsewhere in this proxy statement/prospectus and in the other public filings made by HeartWare or Thoratec with the SEC, which are available without charge. See “Where You Can Find More Information” beginning on page 127 of this proxy statement/prospectus.
 
As a condition to its entering into the merger agreement, Thoratec required certain officers and all of the directors of HeartWare other than Seth Harrison to each enter into a management support agreement with Thoratec and Apple Tree Partners, an investment fund controlled by Seth Harrison, the largest single stockholder of HeartWare, to enter into a stockholder support agreement with Thoratec, in each case with respect to all of the shares of HeartWare common stock, including shares of common stock represented by HeartWare CDIs, beneficially owned by such stockholders on the date thereof, along with all such shares purchased or beneficially acquired after the execution of the support agreements, which we refer to collectively as the support agreement shares. Such HeartWare stockholders, which we refer to as the support agreement stockholders, include Apple Tree Partners, the seven HeartWare directors other than Seth Harrison, and David McIntyre and Jeffrey LaRose, the chief financial officer and chief scientific officer, respectively, of HeartWare. As of the HeartWare record date, the outstanding support agreement shares represent approximately 31.6% of the votes eligible to be cast or to be directed to be cast at the HeartWare special meeting.

Under the support agreements, the support agreement stockholders have agreed to do the following:
 
  •  vote or cause to be voted the support agreement shares in favor of (i) the adoption of the merger agreement, (ii) any other action in furtherance thereof (provided that such action does not require a material amendment (defined below) to the merger agreement to which the support agreement stockholder has not consented) and (iii) any adjournment or postponement recommended by HeartWare with respect to the special meeting; and
 
  •  vote or cause to be voted the support agreement shares against any (i) Acquisition Proposal and (ii) any action or agreement that would result in a breach of any representation, warranty, covenant or obligation of HeartWare in the merger agreement or impair the ability of HeartWare to consummate the merger.
 
The support agreement stockholders have agreed that they will not, nor will they permit any entity under their control to, deposit any of the support agreement shares in a voting trust, grant any proxies or power of attorney with respect to the support agreement shares or subject any of the support agreement shares to any arrangement with respect to the voting of such shares other than agreements entered into with Thoratec.
 
The support agreement stockholders have agreed not to, and not to permit any representative to:

  •  directly or indirectly encourage, initiate or cooperate in a stockholders’ vote or action by consent of HeartWare stockholders in opposition to or in competition with the consummation of the mergers; or
 
  •  unless required by applicable law, make any press release, public announcement or other non-confidential communication with respect to HeartWare or Thoratec, including the merger agreement and the transactions contemplated thereby, without the prior written consent of Thoratec, except that this obligation shall not restrict the support agreement stockholders from acting in their capacities as directors or officers of HeartWare or its subsidiaries, as the case may be.
 
Subject to certain exceptions described in the support agreements, the support agreement stockholders have agreed not to sell, transfer or otherwise dispose of any support agreement shares.
 
The support agreements terminate upon the earliest to occur of:
 
  •  the valid termination of the merger agreement;
 
  •  the effective time of the merger;
 
  •  the date following the adoption of the merger agreement by the HeartWare stockholders;
 
  •  the date that any material amendment shall be made to the merger agreement without the written consent of the support agreement stockholder (with a “material amendment” meaning any valid written amendment to the merger agreement reducing the merger consideration payable to the support agreement stockholder and any other valid written amendment to the merger agreement that would materially delay the consummation of the merger);
 
  •  any amendment to Thoratec’s articles of incorporation or by-laws that would have a disparate effect on holders of HeartWare common stock, as holders of Thoratec common stock at and following the effective time of the merger, relative to other holders of Thoratec common stock; and
 
  •  any amendment to Thoratec’s articles of incorporation to provide for any class of capital stock with rights to distributions or upon a liquidation that are superior to those of Thoratec common stock, other than an amendment in connection with a shareholder rights plan, “poison pill” anti-takeover plan or other similar device.

ACCOUNTING TREATMENT OF THE TRANSACTION
 
Thoratec will account for the merger using the “acquisition method of accounting” as that term is used under SFAS No. 141R, Business Combinations, which Thoratec adopted on January 1, 2009, and uses the fair value concepts defined in SFAS No. 157, Fair Value Measurements for accounting and financial reporting purposes. SFAS No. 141R requires, among other things, that most assets acquired and liabilities assumed be recognized at their fair values as of the acquisition date and that the fair value of in-process research and development be recorded on the balance sheet regardless of the likelihood of success as of the acquisition date. Acquisition-related transaction costs (i.e., advisory, legal, valuation and other professional fees) and certain acquisition-related restructuring charges are not included as a component of consideration transferred but are accounted for as expenses in the periods in which the costs are incurred.
 
The results of operations of HeartWare will be consolidated with those of Thoratec beginning on the date of the merger.

  The Delaware General Corporation Law permits a Delaware corporation to provide in its certificate of incorporation or bylaws that the board of directors shall be divided into as many as three (3) classes of directors with staggered terms of office, with only one (1) class of directors being elected each year for a maximum term of three (3) years.
 
Under HeartWare’s Certificate of Incorporation, the board of directors is divided into three (3) classes — Class I, Class II and Class III — that are, as nearly as possible, of equal size. Generally, each director is elected for a three (3) year term; however, the current directors of Class I shall hold office until the 2009 annual meeting of stockholders, the current directors of Class II shall hold office until the 2010 annual meeting of stockholders and the current directors of Class III shall hold office until the 2011 annual meeting of stockholders.
         
Number of Directors   Under the CCC, the minimum number of directors shall not be less than three(3), subject to limited exceptions, and the maximum number of directors may not be greater than two(2) times the stated minimum number of directors minus one(1). The bylaws or articles of incorporation shall set forth the number of directors of the corporation, or the stated minimum and maximum numbers of directors, with the exact amount to be specified by the board of directors. A bylaw or section of the articles of   The Delaware General Corporation Law provides that the board of directors of a Delaware corporation must consist of one (1) or more directors as fixed by, or in the manner provided in, the corporation’s bylaws, unless the certificate of incorporation fixes the number of directors.
 
Under HeartWare’s Bylaws, subject to the rights of the holders of any series of preferred stock to elect directors under specified circumstances, the number of

    incorporation specifying or changing a fixed number of directors or the maximum or minimum number of directors, or switching from a variable to a fixed board or vice versa, may only be adopted by the approval of the majority of the outstanding shares, provided that such action reducing the number of directors to a number less than five(5) cannot be adopted if the votes cast against its adoption are equal to more than 162/3% of the outstanding shares entitled to vote.
  directors may be fixed from time to time by resolution adopted by a majority of the total number of authorized directors.
 
The HeartWare board of directors currently consists of eight (8) directors.
         
   
 
Thoratec’s By-laws provide that the number of directors shall not be less than five(5) nor more than nine(9). The exact number of directors may be fixed by resolution of the board of directors.
   
         
   
 
The Thoratec board of directors currently consists of nine(9) directors.
   
         
Removal of Directors   Under the CCC, any director or the entire board of directors may be removed, with or without cause, with the approval of a majority of the outstanding shares entitled to vote; however, no director may be removed (unless the entire board is removed) if the number of votes cast against the removal would be sufficient to elect the director under cumulative voting, nor may a director elected by a class or series of shares, voting as a class or series, be removed without the applicable vote of the holders of the shares of that class or series.
 
Under Thoratec’s By-laws, any or all of the directors may be removed without cause if such removal is approved by the affirmative vote or written consent of a majority of the outstanding shares entitled to vote. Unless the entire board of directors is so removed, no director may be removed if(i) the votes cast against removal, or not consenting in writing to such removal in the case of written consent, would be sufficient to elect such director if voted cumulatively at an election at which the same total number of votes was cast or, if such action is taken by written consent, all shares entitled to vote were voted and (ii) the entire number of directors authorized at the time of the director’s
  Under the Delaware General Corporation Law, stockholders holding a majority of shares entitled to vote at an election of directors may remove any directors or the entire board of directors, except that, unless the certificate of incorporation provides otherwise, in the case of a corporation whose board of directors is classified, stockholders may only remove a director for cause or at an election of the class of directors of which such director is a part.
 
Under HeartWare’s Bylaws, subject to the rights of the holders of any series of preferred stock then outstanding, any director, or the entire board of directors may be removed at any time, but only for cause and only by the affirmative vote of the holders of a majority of the voting power of all of the outstanding shares of capital stock entitled to vote generally in the election of directors, voting together as a single class.

Vacancies on the Board of Directors   Under the CCC, any vacancy on the board of directors other than one created by removal of a director may be filled by the approval of the board of directors, unless otherwise provided in the articles of incorporation or bylaws. If the number of directors is less than a quorum, a vacancy may be filled by the unanimous written consent of the directors then in office, by the affirmative vote of a majority of the directors at a meeting held pursuant to notice or waivers of notice, or by a sole remaining director. A vacancy created by removal of a director may be filled only by the shareholders unless board approval is authorized by a corporation’s articles of incorporation or by a bylaw approved by the corporation’s shareholders. The board of directors may declare vacant the office of a director who has been declared of unsound mind by an order of court or convicted of a felony.
 
Under Thoratec’s By-laws, vacancies on the board of directors not caused by removal may be filled by a majority of the directors then in office, regardless of whether they constitute a quorum, or by a sole remaining director. The shareholders may elect a director at any time to fill any vacancy not filled, or which cannot be filled, by the board of directors. No reduction in the authorized number of directors shall have the effect of removing any director prior to the expiration of his or her term in office.
  Under the Delaware General Corporation Law, unless a corporation’s certificate of incorporation or bylaws provide otherwise, vacancies and newly created directorships resulting from a resignation, an increase in the authorized number of directors or otherwise may be filled by a vote of a majority of the directors remaining in office, even if such majority is less than a quorum, or by the sole remaining director.
 
Under HeartWare’s Bylaws, subject to the rights of the holders of any series of preferred stock then outstanding, newly created directorships resulting from any increase in the authorized number of directors or any vacancies in the board of directors resulting from death, resignation, retirement, disqualification or otherwise (including removal from office by a vote of the stockholders) may be filled only by a majority vote of the directors then in office, even if less than a quorum (and not by stockholders), or by the sole remaining director, or, to the extent required by the Certificate of Incorporation, by the stockholders, and directors so chosen shall hold office for a term expiring at the next annual meeting of stockholders or until such director’s successor shall have been duly elected and qualified. No decrease in the number of authorized directors shall shorten the term of any incumbent director.
         
Director Liability   The CCC permits the adoption of provisions by the corporation to eliminate the personal liability of directors for monetary damages, except where such liability is based on:
 
•     Intentional misconduct or knowing and culpable violation of law;
 
•   Acts or omissions that a director believes to be contrary to the best interests of the corporation or its shareholders or that involve the absence of good faith on the part of the director;
 
•   Receipt of an improper personal benefit;
  The Delaware General Corporation Law permits the adoption of a provision in the certificate of incorporation limiting or eliminating the monetary liability of a director to a corporation or its stockholders by reason of a director’s breach of the fiduciary duty of care. However, the law does not permit any limitation of the liability of a director for:
 
•     Breaching the duty of loyalty to the corporation or its stockholders;
 
•   Acts or omissions not in good faith or intentional misconduct or a knowing violation of law;

•     Acts or omissions that show reckless disregard for the director’s duty to the corporation or its shareholders, where the director in the ordinary course of performing a director’s duties should be aware of a risk of serious injury to the corporation or its shareholders;
 
•   Acts or omissions that constitute an unexcused pattern of inattention that amounts to an abdication of the director’s duty to the corporation and its shareholders; or
 
•   Liability for improper distributions, loans or guarantees.
 
•     Obtaining an improper personal benefit from the corporation; or
 
•   Paying an improper dividend or approving an improper repurchase or redemption of the stock of the corporation.
 
Under HeartWare’s Certificate of Incorporation, to the fullest extent permitted by the Delaware General Corporation Law, a director of HeartWare shall not be personally liable to HeartWare or its stockholders for monetary damages for breach of fiduciary duty as a director.
         
   
 
Under Thoratec’s By-laws, to the full extent permitted by law, Thoratec will indemnify its directors, officers, employees and other persons described in Section 317(a) of the CCC against all expenses judgments fines, settlements and other amounts incurred by them in connection with any proceeding as defined in the CCC.
   
         
Variation of Shareholder Rights   The CCC provides that holders of outstanding stock will be entitled to vote as a class upon any proposed amendment to the articles of incorporation that would change the rights, preferences, privileges or restrictions of the shares of such class.
 
Thoratec’s Articles of Incorporation and By-laws contain no provision providing for the variation of rights of outstanding shares of stock.
  The Delaware General Corporation Law provides that the holders of each class of outstanding stock will be entitled to vote as a class upon any proposed amendment to the certificate of incorporation that would alter or change the powers, preferences or special rights of the shares of such class so as to affect them adversely.
 
HeartWare’s Certificate of Incorporation and Bylaws contain no provision providing for the variation of rights of outstanding shares of stock.
         
Waiver of Claims by Shareholders; Indemnification of Officers, Directors and Employees   Under the CCC, a California corporation has the power to indemnify any person who was or is a party or is threatened to be made a party to any proceeding (other than an action by or in the right of the corporation to procure a judgment in its favor) by reason of the fact that that person is or was a director, officer, employee or other agent of the corporation or serving in such capacity to a predecessor corporation of the corporation, against expenses, judgments, fines, settlements and other amounts actually and reasonably incurred in connection with the proceeding if that person acted in good faith and in a   Under the Delaware General Corporation Law, a Delaware corporation must indemnify its present or former directors and officers against expenses (including attorneys’ fees) actually and reasonably incurred to the extent that the officer or director has been successful on the merits or otherwise in defense of any action, suit or proceeding brought against him or her by reason of the fact that he or she is or was a director or officer of the corporation.
 
The Delaware General Corporation Law generally permits a Delaware corporation to indemnify any person who was or is a party or is threatened to be made a party

    manner the person reasonably believed to be in the best interests of the corporation, and in the case of a criminal proceeding, had no reasonable cause to believe the conduct of the person was unlawful.
 
Thoratec’s By-Laws provide that, to the full extent permitted by law, Thoratec shall indemnify its directors, officers, employees and other persons described in Section 317(a) of the CCC, including persons formerly occupying such position, against all expenses (including attorneys’ fees), judgments, fines, settlements and other amounts actually and reasonably incurred by them in connection with any “proceeding”, as that term is used in such Section and including an action by or in the right of the corporation, by reason of the fact that such person is or was a person described by such Section.
 
Upon written request to Thoratec’s board of directors by any person seeking indemnification under the CCC, the board of directors will promptly determine whether the applicable standard of conduct set forth in the CCC has been met and, if so, the board of directors will authorize indemnification. If the board of directors cannot authorize indemnification because the number of directors who are parties to the proceeding with respect to which indemnification is sought prevent the formation of a quorum of directors who are not parties to such proceeding, the board of directors will promptly call a meeting of shareholders. At such meeting, the shareholders shall determine in accordance with the CCC whether the applicable standard of conduct set forth in the CCC has been met and, if so, the shareholders present at the meeting in person or by proxy shall authorize indemnification.
 
To the full extent permitted by law and except as is otherwise determined by the board of directors in the specific instance, expenses incurred by a person seeking indemnification under Thoratec’s By-laws in defending any proceeding covered by the By-laws will be advanced by the corporation prior to the final disposition of the proceeding upon receipt by the
  to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that such person is or was a director, officer, employee or agent of the corporation or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or entity, against expenses (including attorneys’ fees) actually or reasonably incurred by such person in connection with such action, suit or proceeding if the person acted in good faith and in a manner reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe the conduct was unlawful.
 
HeartWare’s Bylaws provide that each person who was or is made a party or is threatened to be made a party to or is involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that he or she or a person of whom he or she is the legal representative, is or was a director or officer of the corporation or is or was serving at the request of the corporation as a director, officer, employee, partner, manager or trustee of another corporation, a partnership, joint venture, trust or other enterprise, including service with respect to employee benefit plans, whether the basis of such proceeding is an alleged action in an official capacity as a director or officer, or in any other capacity while serving as a director or officer, shall be indemnified and held harmless by the corporation to the fullest extent authorized by the Delaware General Corporation Law, against all expenses, liability and loss reasonably incurred or suffered by such person in connection therewith and such indemnification shall continue as to a person who has ceased to be a director or officer and shall inure to the benefit of his or her heirs, executors and administrators.
 
HeartWare’s Bylaws provide that the corporation shall indemnify any such person seeking indemnity in connection with a proceeding initiated by such

HeartWare’s Bylaws provide that the payment of expenses incurred by a director or officer of the corporation in his or her capacity as a director or officer (and not in any other capacity in which service was or is tendered by such person while a director or officer) in defending a proceeding in advance of the final disposition of such proceeding, shall be made only upon delivery to the corporation of an undertaking, by or on behalf of such director or officer, to repay all amounts so advanced if it should be determined ultimately by final judicial decision that such director or officer is not entitled to be indemnified.
         
     
 
HeartWare may, to the extent authorized from time to time by the board of directors, grant rights to indemnification, and to the advancement of related expenses, to any employee or agent of the corporation to the fullest extent of the provisions of the Bylaws with respect to the indemnification of and advancement of expenses to directors and officers of the corporation.
         
     
 
The rights conferred on any person in the indemnification provisions of HeartWare’s Bylaws are not exclusive of any right which such persons may have or acquire under any statute, provision of the Certificate of Incorporation, Bylaw, agreement, vote of stockholders or disinterested directors or otherwise.
         
     
 
Under HeartWare’s Bylaws, HeartWare may maintain insurance to the extent reasonably available, at its expense, to protect itself and any such director, officer, employee or agent of the

      corporation or another corporation, partnership, joint venture, trust or other enterprise against any such expense, liability or loss, whether or not the corporation would have the power to indemnify such person against such expense, liability or loss under the Delaware General Corporation Law.
         
Amendment of Certificate of Incorporation   Under the CCC, an amendment to the articles of incorporation requires the approval of the corporation’s board of directors and a majority of the outstanding shares entitled to vote, either before or after the board approval, although certain minor amendments may be adopted with only the approval of the board of directors.
 
Thoratec’s Articles of Incorporation contain no provisions altering the standards for amendment of the Articles of Incorporation.
  Under the Delaware General Corporation Law, a Delaware corporation’s certificate of incorporation may be amended only if the proposed amendment is approved by (i) the board of directors, (ii) the holders of a majority of the outstanding stock entitled to vote thereon and (iii) the holders of a majority of the outstanding stock of each class entitled to vote thereon as a class.
 
HeartWare’s Certificate of Incorporation contains no provisions altering the standards for amendment of the Certificate of Incorporation.
         
Amendment of Bylaws   Under the CCC, a corporation’s bylaws may be adopted, amended or repealed by either the board of directors or the shareholders of the corporation.
 
Thoratec’s By-laws may be adopted, amended or repealed by the affirmative vote of a majority of the outstanding shares entitled to vote or the board of directors, except as otherwise provided for in the By-laws.
  HeartWare’s Certificate of Incorporation provides that the board of directors and the stockholders are authorized to make, adopt, amend or repeal the Bylaws of the corporation.
 
HeartWare’s Bylaws provide that the Bylaws may be altered, amended or repealed or new Bylaws may be adopted by the affirmative vote of a majority of the directors present at any regular or special meeting of the board of directors at which a quorum is present.
         
     
 
HeartWare’s Bylaws provide that the Bylaws may be altered, amended or repealed or new Bylaws may be adopted by the affirmative vote of the holders of at least 662/3% of the voting power of all of the shares of capital stock of the corporation issued and outstanding and entitled to vote generally in any election of directors, voting together as a single class. Such vote may be held at any annual meeting of stockholders or at any special meeting of stockholders provided that notice of such alteration, amendment, repeal or adoption of new Bylaws shall have been stated in the notice of such special meeting.
         
Business Combinations   The CCC requires that, in a merger of a corporation with a shareholder (or its   Section 203 of the Delaware General Corporation Law, which we refer to as

122

    affiliate) who holds more than 50% but less than 90% of the corporation’s common stock, the other shareholders of the corporation must receive common stock in the transaction, unless all the corporation’s shareholders consent to the transaction.   Section 203, prohibits a Delaware corporation from engaging in a “business combination” with a person owning 15% or more of the corporation’s voting stock for three (3) years following the time that person becomes a 15% stockholder, with certain exceptions.
         
     
 
HeartWare has not opted out of Section 203 in its Certificate of Incorporation and is therefore subject to the terms of this provision of the Delaware General Corporation Law.
         
Approval of Certain Transactions   Under the CCC, there is no statutory restriction on a California corporation’s ability to acquire the business of another corporation. However, a merger or consolidation, sale, lease, conveyance, exchange, transfer or other disposition of all or substantially all of the property of the corporation not in the usual and regular course of the corporation’s business, or a dissolution of the corporation, generally must be approved by the holders of a majority of the shares entitled to vote thereon unless the articles of incorporation provides otherwise. Thoratec’s Articles of Incorporation does not provide otherwise.   Under the Delaware General Corporation Law, there is no statutory restriction on a Delaware corporation’s ability to acquire the business of another corporation. However, a merger or consolidation, sale, lease, exchange or other disposition of all or substantially all of the property of the corporation not in the usual and regular course of the corporation’s business, or a dissolution of the corporation, generally must be approved by the holders of a majority of the shares entitled to vote thereon unless the certificate of incorporation provides for a greater vote. HeartWare’s Certificate of Incorporation does not provide for a greater vote.
         
Purchases of Stock from Certain Persons   Thoratec’s Articles of Incorporation and By-laws do not limit Thoratec’s power to purchase shares of Thoratec stock from any person.   HeartWare’s Certificate of Incorporation and Bylaws do not limit HeartWare’s power to purchase shares of HeartWare stock from any person.
         
Inspection of Books and Records; Shareholder Lists   Under the CCC, any shareholder may inspect Thoratec’s shareholder list for a purpose reasonably related to the person’s interest as a shareholder. The CCC provides, in addition, for an absolute right to inspect and copy the corporation’s shareholder list by persons holding an aggregate of 5% or more of the corporation’s voting shares, or shareholders holding an aggregate of 1% or more of such shares who have contested the election of directors.
 
Under the CCC, any shareholder may examine the accounting books and records and the minutes of the shareholders and the board and its committees, provided that the inspection is for a purpose reasonably related to the shareholder’s interests as a shareholder.

  Under the Delaware General Corporation Law, upon a proper written demand, any stockholder may inspect HeartWare’s books and records for a proper purpose.
 
Under the Delaware General Corporation Law, a complete list of stockholders entitled to vote at any meeting of stockholders, arranged in alphabetical order and showing the address of each stockholder and the number of shares registered in each stockholder’s name, shall be open to the examination of any stockholder, for any purpose germane to the meeting, during ordinary business hours for a period of at least ten (10) days prior to the meeting, either (i) on a reasonably accessible electronic network, or (ii) during ordinary business hours, at the principal place of business of the corporation.

    In addition, the CCC limits the right of inspection of shareholder lists to record shareholders, whereas Delaware has extended that right to beneficial owners of shares.   Under the Delaware General Corporation Law, the stock list shall also be kept at the place of the meeting (if the meeting is to be held at a place) during the whole time thereof and shall be open to the examination of any such stockholder who is present. If the meeting is held by means of remote communication, the list shall be open to the examination of any stockholder during the whole time of the meeting on a reasonably accessible electronic network. This list shall presumptively determine the identity of the stockholders entitled to vote at the meeting.
         
Stockholder Rights Plan   The CCC does not include a statute expressly validating shareholder rights plans.
 
Thoratec has a shareholder rights plan. Under the rights plan, Thoratec distributed one(1) purchase right for each share of common stock outstanding at the close of business on May 17, 2002. If a person or group acquires 15% or more of Thoratec’s common stock in a transaction not pre- approved by Thoratec’s board of directors, each right will entitle its holder, other than the acquirer, to buy Thoratec’s common stock at 50% of its market value for the right’s then-current exercise price (initially $70.00). In addition, if an unapproved party acquires more than 15% of Thoratec’s common stock, and Thoratec is later acquired by the unapproved party or in a transaction in which all shareholders are not treated alike, shareholders with unexercised rights, other than the unapproved party, will be entitled to purchase common stock of the merger party or asset buyer with a value of twice the exercise price of the rights. Each right also becomes exercisable for one one-thousandth (0.001) of a share of Thoratec’s Series RP preferred stock at the right’s then-current exercise price ten (10) days after an unapproved third-party makes, or announces an intention to make, a tender offer or exchange offer that, if completed, would result in the unapproved party acquiring 15% or more of Thoratec’s common stock. Thoratec’s board of directors may redeem the rights for a nominal amount before an event that
  Under the Delaware General Corporation Law, HeartWare’s board of directors could adopt a stockholder rights plan without stockholder approval.
 
HeartWare does not currently have a stockholder rights plan.

    causes the rights to become exercisable. The rights will expire on May 2, 2012.    
         
Dissenters’ Rights   Under the CCC, shareholders of a California corporation whose shares do not have transfer restrictions imposed by the corporation or by law and are listed on a national securities exchange (including the NASDAQ) or on a list of over-the-counter margin stocks issued by the Board of Governors of the Federal Reserve System generally, which we refer to as a listed company, do not have dissenters’ rights unless the holders of at least 5% of the class of outstanding shares demand the right. Additionally, dissenters’ rights are unavailable if the shareholders of a corporation or the corporation itself, or both, immediately prior to a reorganization will own (immediately after the reorganization) more than five- sixths (5/6) of the voting power of the surviving or acquiring corporation or its parent. Under California law, a shareholder attempting to assert dissenters’ rights must hold capital stock that satisfies each of the following requirements:(i) the shares must have been outstanding on the company’s record date; (ii) the shares must not have been voted in favor of the reorganization (or, in the case of a listed company, must have been voted against the reorganization); (iii) the holder of such shares must make a written demand that the company repurchase such shares of capital stock at fair market value; and (iv) the holder of such shares must submit certificates for endorsement. A vote by proxy or in person against the merger does not in and of itself constitute a demand for appraisal under California law. California law generally affords dissenters’ rights in reorganizations that are structured as sales of assets.
 
Thoratec shareholders do not have dissenters’ rights in connection with the merger.
  Under the Delaware General Corporation Law, in certain situations, dissenters’ rights may be available in connection with a merger or a consolidation. Dissenters’ rights are not available under the Delaware General Corporation Law to stockholders of the surviving corporation when a corporation is to be the surviving corporation and no vote of its stockholders is required to approve the merger. In addition, no dissenters’ rights are available under the Delaware General Corporation Law to holders of shares of any class or series of stock which is either:
 
•     listed on a national securities exchange; or
 
•   held of record by more than 2,000 stockholders.
 
Notwithstanding the above, dissenters’ rights shall be available to those stockholders who are required by the terms of the merger or consolidation to accept for that stock anything other than:
 
•   shares of stock of the corporation surviving or resulting from the merger or consolidation, or depository receipts in respect thereof;
 
•   shares of stock of another corporation, or depository receipts in respect thereof, which, as of the effective date of the merger or consolidation, are listed on a national securities exchange or held of record by more than 2,000 stockholders;
 
•   cash in lieu of fractional shares or fractional depository receipts in the foregoing paragraphs; or
 
•   any combination of the items listed above.
         
     
 
HeartWare stockholders have dissenters’ rights in connection with the merger.
         
Derivative Suits   The CCC provides that a shareholder bringing a derivative action on behalf of a corporation need not have been a shareholder at the time of the transaction in question, provided that certain tests are met. The CCC also provides that the   The Delaware General Corporation Law requires that the stockholder bringing a derivative suit must have been a stockholder at the time of the wrong complained or that he received the stock by operation of law from a person who

In addition, the stockholder must remain a stockholder throughout the litigation. Furthermore, a stockholder may not sue derivatively unless he or she first makes a demand on the corporation that it bring suit and such demand has been refused, unless it is shown that the demand would have been futile.
         
Preemptive Rights   Under the CCC, a shareholder is not entitled to preemptive rights to subscribe for additional issuances of stock, or any security convertible into stock, unless the rights are specifically granted in the articles of incorporation.
 
Thoratec’s Articles of Incorporation do not provide for any such preemptive rights.
  Under the Delaware General Corporation Law, security holders of a corporation only have preemptive rights as may be provided in the corporation’s certificate of incorporation.
 
HeartWare’s Certificate of Incorporation does not provide for preemptive rights.

Section 2.01.  The Mergers.  (a) The Mergers.  At the Effective Time, upon the terms and subject to satisfaction or valid waiver of the conditions set forth in this Agreement, Merger Subsidiary shall be merged with and into the Company in the Merger, whereupon the separate existence of Merger Subsidiary shall cease, and the Company shall continue as the Intermediate Surviving Corporation. If, and only if, the Continuity Percentage


A-8


Table of Contents

equals or exceeds the Reorganization Threshold, immediately following the Effective Time, the Intermediate Surviving Corporation shall be merged with and into Merger Subsidiary Two in the Second Merger, whereupon the separate existence of the Intermediate Surviving Corporation shall cease, and Merger Subsidiary Two shall continue as the Surviving Corporation. For the avoidance of doubt, if the Continuity Percentage is less than the Reorganization Threshold, the Parties shall not, and shall have no obligation to, consummate the Second Merger pursuant to this Agreement.
 
(b) The Closing.  Subject to the terms and conditions of this Agreement, the closing of the Mergers (the “Closing”) shall take place on a day that is a Business Day (i) at the offices of Latham & Watkins LLP, 140 Scott Drive, Menlo Park, California 94025 at 9:00 a.m. (Pacific time), no later than the third (3rd) Business Day following the satisfaction of the conditions set forth in Article 7 (other than (A) those conditions that are waived in accordance with the terms of this Agreement by the Party or Parties for whose benefit such conditions exist and (B) any such conditions that, by their terms, are not capable of being satisfied until the Closing) or (ii) at such other place, time and/or date as the Parties may otherwise agree. The date upon which the Closing shall occur is referred to herein as the “Closing Date.”
 
(c) The Merger.  At the Closing, the Parties shall cause the Merger to be consummated by filing a certificate of merger (the “Certificate of Merger”) with the Secretary of State of the State of Delaware, in such form as required by, and properly executed in accordance with, Delaware Law. The Merger shall become effective at such time as the Certificate of Merger is duly filed with the Secretary of State of the State of Delaware or at such other time as is agreed upon by the Parties and specified as the effective time in the Certificate of Merger (the “Effective Time”). At the Effective Time, the effect of the Merger shall be as provided in this Agreement and the applicable provisions of Delaware Law. Without limiting the generality of the foregoing, at the Effective Time, all the property, rights, privileges, immunities, powers and franchises of the Company and Merger Subsidiary shall vest in the Intermediate Surviving Corporation, and all debts, liabilities and duties of the Company and Merger Subsidiary shall become the debts, liabilities and duties of the Intermediate Surviving Corporation.
 
(d) The Second Merger.  If, and only if, the Continuity Percentage equals or exceeds the Reorganization Threshold, at the Closing, immediately following the consummation of the Merger, the Parties shall cause the Second Merger to be consummated by filing a certificate of merger (the “Second Merger Certificate of Merger”) with the Secretary of State of the State of Delaware, in such form as required by, and properly executed in accordance with, Delaware Law. The Second Merger shall become effective at such time as the Second Merger Certificate of Merger is duly filed with the Secretary of State of the State of Delaware or at such other time as is agreed upon by the Parties and specified as the effective time in the Second Merger Certificate of Merger (the “Second Merger Effective Time”); provided, however, that in no event shall the Second Merger Effective Time precede the Effective Time. At the Second Merger Effective Time, the effect of the Second Merger shall be as provided in this Agreement and the applicable provisions of Delaware Law. Without limiting the generality of the foregoing, at the Second Merger Effective Time, all the property, rights, privileges, immunities, powers and franchises of the Intermediate Surviving Corporation and Merger Subsidiary Two shall vest in the Surviving Corporation, and all debts, liabilities and duties of the Intermediate Surviving Corporation and Merger Subsidiary Two shall become the debts, liabilities and duties of the Surviving Corporation.
 
Section 2.02.  Conversion of Shares.  At the Effective Time, by virtue of the Merger and without any action on the part of the Company, Parent, Merger Subsidiary or Merger Subsidiary Two or the holders of any shares of capital stock of the Company, Parent or Merger Subsidiary:
 
(a) Merger Subsidiary Common Stock.  Each share of common stock of Merger Subsidiary outstanding immediately prior to the Effective Time shall be converted into and become one (1) share of common stock of the Intermediate Surviving Corporation with the same rights, powers and privileges as the shares so converted and shall constitute the only outstanding shares of capital stock of the Intermediate Surviving Corporation.
 
(b) Company Stock.  Subject to Section 2.02(e), each share of Company Stock (each, a “Share”) issued and outstanding immediately prior to the Effective Time (other than Treasury Shares that will be cancelled in accordance with Section 2.02(d) and any shares of Company Stock (“Dissenting Shares”) which are held by Company Stockholders exercising appraisal rights in accordance with Section 262 of the Delaware Law (“Dissenting Stockholders”)) shall automatically be converted into the right to receive (i) $14.30 in cash,

Table of Contents

without interest (the “Cash Consideration”) and (ii) 0.6054 validly issued, fully paid and non-assessable shares of Parent Stock, subject to the adjustments set forth in Section 2.02(c) (the “Stock Consideration” and together with the Cash Consideration, the “Merger Consideration”).
 
(c) Adjustments to Stock Consideration.  Notwithstanding the foregoing:
 
(i) If the Average Parent Stock Price is less than or equal to $18.38 (the “Walk-Away Price”), the Company shall have the right to give written notice to Parent (a “Walk-Away Notice”), of the Company’s election to terminate this Agreement in accordance with Section 8.01(d)(iii) hereof. Any Walk-Away Notice shall be delivered to Parent no later than 5:00 p.m. Pacific time on the second (2nd) Business Day following the Measurement End Date. If the Company delivers a timely Walk-Away Notice, Parent shall have the right to give written notice to the Company (the “Top-Up Notice”), of Parent’s election to increase (A) the per share Stock Consideration otherwise payable hereunder to a number of shares of Parent Stock equal to (i) the product of (x) the Stock Consideration, (y) $26.25 and (z) seventy percent (70%) divided by (ii) the Average Parent Stock Price and (B) the Company Stock Award Exchange Ratio to (i) the product of (x) the Company Stock Award Exchange Ratio, (y) $26.25 and (z) seventy percent (70%) divided by (ii) the Average Parent Stock Price. Any Top-Up Notice shall be delivered to the Company no later than 5:00 p.m. Pacific time on the second (2nd) Business Day following delivery to Parent of the Walk-Away Notice. In the event that Parent delivers a Top-Up Notice in response to a duly delivered Walk-Away Notice in accordance with this Section 2.02(c)(i), (1) the Company shall not be entitled to terminate this Agreement pursuant to Section 8.01(d)(iii) and (2) for all purposes under this Agreement, the Stock Consideration and the Company Stock Award Exchange Ratio shall mean the Stock Consideration and the Company Stock Award Exchange Ratio as adjusted pursuant to this Section 2.02(c)(i).
 
(ii) If the Average Parent Stock Price is greater than or equal to $34.13, Parent shall have the right to give written notice to the Company (a “Reset Notice”), of Parent’s election to decrease (A) the per share Stock Consideration otherwise payable hereunder to a number of shares of Parent Stock equal to (i) the product of (x) the Stock Consideration, (y) $26.25 and (z) one hundred thirty percent (130%) divided by (ii) the Average Parent Stock Price and (B) the Company Stock Award Exchange Ratio to (i) the product of (x) the Company Stock Award Exchange Ratio, (y) $26.25 and (z) one hundred thirty percent (130%) divided by (ii) the Average Parent Stock Price. Any Reset Notice shall be delivered to the Company no later than 5:00 p.m. Pacific time on the second (2nd) Business Day following the Measurement End Date. In the event that Parent delivers a Reset Notice in accordance with this Section 2.02(c)(ii), for all purposes under this Agreement, the Stock Consideration and the Company Stock Award Exchange Ratio shall mean the Stock Consideration and the Company Stock Award Exchange Ratio as adjusted pursuant to this Section 2.02(c)(ii).
 
(d) Treasury Shares.  Each Share held in the treasury of the Company or owned, directly or indirectly, by Parent, Merger Subsidiary or Merger Subsidiary Two immediately prior to the Effective Time (collectively, “Treasury Shares”) shall automatically be cancelled and retired and shall cease to exist, and no consideration shall be delivered in exchange therefor.
 
(e) Treatment of Fractional Shares.  Notwithstanding any other provision of this Agreement, no fractional shares of Parent Stock will be issued and, in lieu of any fractional share of Parent Stock that otherwise would be issuable pursuant to the Merger, each holder of Shares (and, to the extent applicable, CDIs) who otherwise would be entitled to receive a fraction of a share of Parent Stock pursuant to the Merger will be paid an amount in cash, without interest, in lieu thereof equal to such holder’s proportionate interest in the net proceeds from the sale or sales by the Exchange Agent on behalf of such holder of the aggregate fractional shares of Parent Stock that such holder otherwise would be entitled to receive. As soon as practicable following the completion of the Merger, the Exchange Agent shall determine the excess of (i) the number of whole shares of Parent Stock issuable to the former holders of Shares pursuant to the Merger including fractional shares, over (ii) the aggregate number of whole shares of Parent Stock to be distributed to former holders of Shares (and, to the extent applicable, CDIs) (such excess being collectively called the “Excess Parent Stock”). The Exchange Agent shall, as promptly as reasonably practicable following the Effective Time (and in any event


A-10


Table of Contents

within five (5) Business Days after the date upon which the Certificate (or affidavit(s) of loss in lieu thereof) that would otherwise result in the issuance of such fractional shares of Parent Stock has been received by the Exchange Agent), sell the Excess Parent Stock on NASDAQ at the then prevailing prices on NASDAQ and such sales shall be executed in round lots to the extent practicable. Parent shall pay all commissions, transfer Taxes and other out-of-pocket transaction costs, including the expenses and compensation of the Exchange Agent and costs associated with calculating and distributing the respective cash amounts payable to the applicable former holders of Shares, incurred in connection with such sales of Excess Parent Stock. Until the proceeds of such sales have been distributed to the former holders of Shares (and, to the extent applicable, CDIs) to whom fractional shares of Parent Stock otherwise would have been issued in the Merger, the Exchange Agent will hold such proceeds in trust for such former holders. As soon as practicable after the determination of the amount of cash to be paid to former holders of Shares (and, to the extent applicable, CDIs) in respect of any fractional shares of Parent Stock, the Exchange Agent shall distribute such amounts to such former holders.
 
(f) Changes in Capitalization.  If, between the date of this Agreement and the Effective Time, any change in the outstanding shares of capital stock of the Company or Parent shall occur, including by reason of any reclassification, recapitalization, stock split or combination, exchange or readjustment of shares, or any stock dividend thereon with a record date during such period, but excluding any change that results from any exercise of Company Stock Awards to purchase shares of Company Stock, the Cash Consideration, the Stock Consideration, the Company Stock Award Amount and the Company Stock Award Exchange Ratio and any other amounts payable pursuant to this Agreement shall be adjusted appropriately to account for such change.
 
(g) Limitation on Issuance of Parent Stock.  Notwithstanding any provision to the contrary in this Agreement, if the Company delivers a Walk-Away Notice and Parent elects to deliver a Top-Up Notice in response thereto, and, as a result of Parent’s delivery of such Top-Up Notice, after giving effect to the increase in the Stock Consideration and the Company Stock Award Exchange Ratio that would result therefrom in accordance with Section 2.02(c)(i), the issuance of shares of Parent Stock and Parent Incentive Options in connection with the transactions contemplated by this Agreement would require the approval of Parent’s stockholders under NASDAQ Marketplace Rule 4350, then (i) the per share Stock Consideration shall be reduced to a number of shares of Parent Stock such that the aggregate number of shares of Parent Stock issued or to be issued in connection with the transactions contemplated by this Agreement shall be equal to the maximum number of shares of Parent Stock that may be issued without requiring the approval of Parent’s stockholders under NASDAQ Marketplace Rule 4350, and, for all purposes under this Agreement, the Stock Consideration shall mean the Stock Consideration as so adjusted and (ii) the per share Cash Consideration shall be increased by an amount equal to the product of (A) the number of shares by which the per share Stock Consideration has been reduced pursuant to the preceding Section 2.02(g)(i) and (B) the Average Parent Stock Price.
 
Section 2.03.  Treatment of Options and Other Equity-Based Awards.  (a) Unvested Incentive Stock Options.  The terms of outstanding options to purchase shares of Company Stock granted or issued under incentive option agreements or similar arrangements with directors, employees or consultants of the Company or under the HeartWare International, Inc. Incentive Option Terms: Non-Executive Directors or the HeartWare International, Inc. 2008 Stock Incentive Plan (each, a “Company Incentive Option”) shall be adjusted as necessary to provide that, at the Effective Time, each Company Incentive Option that is unvested and outstanding immediately prior to the Effective Time, including each Company Incentive Option issued prior to the Effective Time in accordance with Section 6.01(c)(i)(B), shall cease to represent the right to acquire shares of Company Stock and shall instead be converted into, and deemed to constitute, an option to acquire, on the same terms and conditions as were applicable under such Company Incentive Option, a number of shares of Parent Stock (each, a “Parent Incentive Option”) equal to the product of (a) the number of shares of Company Stock represented by such unvested Company Incentive Option and (b) the Company Stock Award Exchange Ratio, rounded down, if necessary, to the nearest whole share of Parent Stock and such Parent Incentive Option shall have an exercise price per share (rounded up to the nearest cent) equal to (x) the per share exercise price specified in such Company Incentive Option divided by (y) the Company Stock Award Exchange Ratio; provided, however, that the exercise price and the number of shares of Parent Stock subject to each Parent Incentive Option shall be determined in a


A-11


Table of Contents

manner consistent with the requirements of Section 409A of the Code, and to the extent necessary to avoid treating the assumption of such Company Incentive Options as a grant of a new stock option under Section 409A of the Code, the exercise price of Parent Incentive Options shall be increased. For purposes of this Section 2.03(a), any exercise price for a Parent Incentive Option that is measured in Australian dollars shall be deemed to be converted to U.S. dollars for all purposes hereunder at an exchange rate of 1.5265 Australian dollars for each U.S. dollar.
 
(b) Vested Incentive Stock Options and Employee Stock Options.  The terms of each outstanding vested Company Incentive Option and each outstanding option to purchase shares of Company Stock issued under the HeartWare International, Inc. Employee Stock Option Plan (each, a “Company ESOP” and, together with the Company Incentive Options, each, a “Company Option”) shall be adjusted as necessary to provide that, at or immediately prior to the Effective Time, each such Company Option, whether or not exercisable or vested, that is outstanding immediately prior to the Effective Time (each, a “Cancelled Company Option”) shall be cancelled and will convert into the right to receive a cash payment, without interest, equal to (i) the excess, if any, of the Company Stock Award Amount over the applicable exercise price per share of Company Stock of such Cancelled Company Option multiplied by (ii) the number of shares of Company Stock such holder could have purchased (assuming full vesting of each outstanding option to purchase shares of Company Stock issued under the HeartWare International, Inc. Employee Stock Option Plan) had such holder exercised such Cancelled Company Option in full immediately prior to the Effective Time. For purposes of this Section 2.03(b), any exercise price for a Company ESOP that is measured in Australian dollars shall be deemed to be converted to U.S. dollars for all purposes hereunder at an exchange rate of 1.5265 Australian dollars for each U.S. dollar.
 
(c) Stock-Based Awards.  The terms of each right of any kind, contingent or accrued, to receive shares of Company Stock or benefits measured by the value of a number of shares of Company Stock, and each award of any kind consisting of shares of Company Stock, issued under the HeartWare International, Inc. Restricted Stock Unit Plan, the HeartWare International, Inc. 2008 Stock Incentive Plan or the HeartWare International, Inc. Employee Stock Option Plan (including restricted stock, restricted stock units, deferred stock units and dividend equivalents), other than Company Incentive Options and Company ESOPs (each, a “Company Stock-Based Award” and, together with the Company Incentive Options and Company ESOPs, the “Company Stock Awards”) shall be adjusted as necessary to provide that, at or immediately prior to the Effective Time, each such Company Stock-Based Award, whether or not exercisable or vested, that is outstanding immediately prior to the Effective Time shall be cancelled and will convert into the right to receive a cash payment, without interest, equal to the Company Stock Award Amount multiplied by the number of shares of Company Stock the holder of such Company Stock-Based Award would have received had such Company Stock-Based Award been fully earned, vested and exercisable and been exercised or settled immediately prior to the Effective Time.

foregoing in this clause (iii), an “Adverse Recommendation Change”) or (iv) enter into any agreement, agreement in principle, letter of intent, or other similar instrument relating to any Acquisition Proposal. The Company shall, and shall cause each of its Subsidiaries and its and their Representatives to, immediately cease and cause to be terminated any discussions or negotiations with any Third Party (other than Parent and its Representatives) that may be ongoing as of the date hereof with respect to any actual or potential Acquisition Proposal. The Company shall use its commercially reasonable efforts to obtain, in accordance with the terms of any applicable confidentiality agreement, the return or destruction of any confidential information previously furnished to any such Person by the Company, any of its Subsidiaries or any of its or their Representatives.

(c) The Company shall promptly (and in any event within two (2) Business Days) advise Parent orally and in writing of (i) the receipt of any indication in writing that a Third Party is considering or may be considering making an Acquisition Proposal or (ii) the receipt of any Acquisition Proposal, in each case, along with the identity of the Person making any such Acquisition Proposal, and, to the extent available, the Company shall provide Parent with a copy or a written summary of the material terms of any such Acquisition Proposal. The Company shall keep Parent reasonably informed of the status on a current basis (including any change to the material terms) of any such Acquisition Proposal, potential Acquisition Proposal or information request. Following a determination by the Board of Directors of the Company that an Acquisition Proposal constitutes a Superior Proposal, the Company shall deliver to Parent a written notice advising it that the Board of Directors of the Company has made such

determination together with a copy of any written summary or any draft or definitive agreements related to such Superior Proposal and a summary of the material terms of such Superior Proposal. The Company agrees that it shall not, and shall cause its Subsidiaries not to, enter into any confidentiality agreement or other agreement with any Person subsequent to the date of this Agreement which prohibits the Company from providing such information to Parent.
 
(d) Prior to furnishing any information to or entering into discussions or negotiations with any Person making an Acquisition Proposal pursuant to Section 6.04(b), the Company shall receive from such Person an executed confidentiality agreement, the terms of which shall be no less favorable to the Company than, in the aggregate, those contained in the Confidentiality Agreement dated as of November 14, 2008 between the Company and Parent (the “Confidentiality Agreement”) (a copy of which shall be provided for informational purposes only to Parent).

(e) Notwithstanding anything to the contrary contained herein, nothing contained in this Agreement shall prohibit or restrict the Company or the Board of Directors of the Company from (a) taking and/or disclosing to the Company Stockholders a position contemplated by Rule 14d-9 or Rule 14e-2 promulgated under the Exchange Act or (b) making any disclosure to the stockholders of the Company if, the Board of Directors of the Company, determines in good faith (after consultation with its outside legal counsel and financial advisors) that it is required to do so under Applicable Law (including Rule 14d-9 and Rule 14e-2 promulgated under the Exchange Act); provided, however, that in no event shall this Section 6.04(e) affect the obligations of the Company specified in Section 6.04(b).

No investigation made or information provided, made available or delivered to Parent, Merger Subsidiary, Merger Subsidiary Two or any of their respective Representatives pursuant to this Section 6.05 shall affect any of the representations, warranties, covenants, rights or remedies, or the conditions to the obligations of, the Parties hereunder.

Without limiting the generality of the foregoing, the Parties will use their respective reasonable best efforts to (a) prepare and file as soon as practicable all forms, registrations and notices relating to antitrust, competition, trade or other regulatory matters that are required by Applicable Law to be filed in order to consummate the Merger and the other transactions contemplated hereby, and take such actions as are reasonably necessary to obtain any requisite approvals, consents, orders, exemptions or waivers by, or to avoid an action or proceeding by, any Governmental Authority relating to antitrust, competition, trade or other regulatory matters (collectively, “Regulatory Approvals”), including (i) any Notification and Report Forms and related material required in connection with the HSR Act with the United States Federal Trade Commission (“FTC”) and with the Antitrust Division of the United States Department of Justice (“Antitrust Division”) in connection with the HSR Act (which shall be filed no later than ten (10) Business Days following the date of this Agreement) and (ii) any form or report required by any other Governmental Authority relating to any other Regulatory Approval, (b) take all actions necessary to cause all conditions set forth in Article 7 (including the prompt termination of any waiting period under the HSR Act (including any extension of the initial thirty (30) day waiting period thereunder)) to be satisfied as soon as practicable and (c) execute and deliver any additional instruments necessary to consummate the Mergers and to fully carry out the purposes of this Agreement; provided, however, that the Parties hereto understand and agree that the reasonable best efforts of any Party hereto shall not require any Party or its Affiliates or Subsidiaries to: (i) agree to or effect any divestiture or hold-separate order, or enter into any license or similar agreement with respect to, or agree to restrict its ownership or operation of, any business or assets of any Party or any of its Affiliates or Subsidiaries, (ii) enter into, amend, or agree to enter into or amend, any contracts of any Party or any of its Affiliates or Subsidiaries or (iii) otherwise waive, abandon or alter any material rights or obligations of any Party or any of its Subsidiaries or Affiliates.

Subject to Applicable Law and the attorney-client and similar applicable privileges, Parent and the Company shall have the right to review in advance, and, to the extent reasonably practicable, each will consult the other on, all the information relating to the other and each of their respective Subsidiaries and Affiliates that appears in any filing made with, or written materials submitted to, any Governmental Authority in connection with the Mergers and the other transactions contemplated hereby.
 
(c) Each Party shall (a) subject to Section 6.06(d) below, respond as promptly as reasonably practicable to any inquiries or requests for additional information and documentary material received from the FTC or the Antitrust Division and to all inquiries and requests received from any State Attorney General or other Governmental Authority in connection with Regulatory Approvals and antitrust matters, (b) not extend any waiting period or agree to refile under the HSR Act (except with the prior written consent of the other Parties hereto, which consent shall not be unreasonably withheld, conditioned or delayed) and (c) not enter into any agreement with the FTC or the Antitrust Division agreeing not to consummate the Mergers or the other transactions contemplated by this Agreement. Except for the Mergers and without limiting the Parties’ other obligations under this Agreement, none of the Parties shall enter into or consummate any merger or other acquisition of a business or any similar transaction (other than a license of Intellectual Property entered into in the ordinary course of business), that would reasonably be expected to make it less likely that the conditions set forth in Section 7.01(b) and Section 7.01(c) would be satisfied in a timely manner.

Section 6.08.  Public Announcements.  The initial press release with respect to this Agreement, the Mergers and the other transactions contemplated hereby shall be a joint release mutually agreed upon by the Company and Parent.

None of the covenants or agreements of the Parties in this Agreement shall survive the Effective Time, other than (a) the covenants and agreements of the Parties contained in this Article 9, in Article 2 and in Sections 6.10 and 6.11 and (b) those other covenants and agreements contained herein that by their terms apply, or that are to be performed in whole or in part, after the Effective Time, in each case which shall survive the consummation of the Mergers until fully performed.
 
Section 9.03.  Amendments and Waivers.  (a) Any provision of this Agreement may be amended prior to the Effective Time if, but only if, such amendment or waiver is in writing and is signed, in the case of an amendment, by each Party; provided, however, that, after approval of the Agreement by the stockholders of the Company, no amendment that, by Applicable Law or in accordance with the rules of any relevant stock exchange, requires further approval by such stockholders may be made without such stockholder approval.
 
(b) At any time prior to the Effective Time, Parent, Merger Subsidiary and Merger Subsidiary Two, on the one hand, or the Company, on the other hand, may, to the extent permitted by Applicable Law, (a) extend the time for the performance of any of the obligations or other acts of the other Parties under this Agreement, (b) waive any inaccuracies in the representations and warranties of the other Parties contained herein or in any instrument delivered pursuant hereto or (c) waive compliance with any of the covenants or agreements of the other Parties or conditions to the obligations of the waiving Parties contained herein; provided, however, that after any approval of this Agreement by the stockholders of the Company, no extension or waiver that, by Applicable Law or in accordance with the rules of any relevant stock exchange, requires further approval by such stockholders may be made without such stockholder approval. Any agreement on the part of a Party to any such extension or waiver shall be valid only if set forth in a written instrument signed by such Party. The failure or delay of any Party to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of those rights, nor shall any single or partial exercise of any right under this Agreement preclude any other or further exercise of any rights hereunder.
 
Section 9.04.  Expenses.  Except as otherwise expressly set forth in this Agreement, all Expenses incurred in connection herewith and the transactions contemplated hereby shall be paid by the Party incurring, or required to incur, such Expenses, whether or not the Mergers are consummated.
 
Section 9.05.  Mutual Drafting; Headings.  Each Party has participated in the drafting of this Agreement, which each Party acknowledges is the result of extensive negotiations between the Parties.

Subject to the foregoing, this Agreement will be binding upon, inure to the benefit of and be enforceable by the Parties and their respective successors and permitted assigns.
 
(b) Nothing in this Agreement, express or implied, shall confer upon any Person other than the Parties hereto any rights, benefits or remedies of any nature whatsoever under or by reason of this Agreement; provided that the

Each Party hereby irrevocably waives, and agrees not to assert as a defense, counterclaim or otherwise, in any legal action, suit or proceeding arising out of, based upon or relating to this Agreement, (a) any claim that it is not personally subject to the jurisdiction of the above named courts for any reason other than the failure to serve process in accordance with Section 9.01, (b) any claim that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) and (c) to the fullest extent permitted by Applicable Law, any claim that (i) the suit, action or proceeding in such court is brought in an inconvenient forum, (ii) the venue of such suit, action or proceeding is improper or (iii) this Agreement, or the subject mater hereof, may not be enforced in or by such courts. Each Party agrees that notice or the service of process in any action, suit or proceeding arising out of, based upon or relating to this Agreement or the rights and obligations arising hereunder shall be properly served or delivered if delivered in the manner contemplated by Section 9.01.

Section 9.11.  Entire Agreement.  This Agreement (together with the Exhibits, the Company Disclosure Schedule, the Parent Disclosure Schedule and the other instruments delivered pursuant hereto), the Loan Documents and the Confidentiality Agreement constitute the entire agreement of the Parties and supersede all prior agreements and undertakings, both written and oral, among the Parties, or any of them, with respect to the subject matter hereof and thereof.

(b) Each Guarantor and the Lender hereby confirms that it is the intention of all such Persons that this Guaranty and the Obligations of each Guarantor hereunder not constitute a fraudulent transfer or conveyance for purposes of any law related to fraudulent transfer or conveyance to the extent applicable to this Guaranty and the Obligations of the Guarantor hereunder. To effectuate the foregoing intention, the Lender and the Guarantors hereby irrevocably agree that the Obligations of each Guarantor under this Guaranty at any time shall be limited to the maximum amount as will result in the Obligations of such Guarantor under this Guaranty not constituting a fraudulent transfer or conveyance.
 
Section 7.02.  Payment by Guarantors.  Guarantors hereby jointly and severally agree, in furtherance of the foregoing and not in limitation of any other right which the Lender may have at law or in equity against any Guarantor by virtue hereof, that upon the failure of Borrower to pay any of the Guaranteed Obligations when and as the same shall become due, whether at stated maturity, by required prepayment, declaration, acceleration, demand or otherwise (including amounts that would become due but for the operation of the automatic stay under Section 362(a) of the Bankruptcy Code), Guarantors will upon demand pay, or cause to be paid, in cash, to the Lender, an amount equal to the sum of the unpaid principal amount of all Guaranteed Obligations then due as aforesaid, accrued and unpaid interest on such Guaranteed Obligations (including interest which, but for Borrower’s becoming the subject of a case under the Bankruptcy Code, would have accrued on such Guaranteed Obligations, whether or not a claim is allowed against Borrower for such interest in the related bankruptcy case) and all other Guaranteed Obligations then owed to the Lenders as aforesaid.

B-15


Table of Contents

Obligations. In furtherance of the foregoing and without limiting the generality thereof, each Guarantor agrees as follows:
 
(a) this Guaranty is a guaranty of payment when due and not of collectability. This Guaranty is a primary obligation of each Guarantor and not merely a contract of surety;
 
(b) the Lender may enforce this Guaranty upon the occurrence of an Event of Default notwithstanding the existence of any dispute between Borrower and the Lender with respect to the existence of such Event of Default;
 
(c) the obligations of each Guarantor hereunder are independent of the obligations of Borrower and the obligations of any other guarantor (including any other Guarantor) of the obligations of Borrower, and a separate action or actions may be brought and prosecuted against such Guarantor whether or not any action is brought against Borrower or any of such other guarantors and whether or not Borrower is joined in any such action or actions;
 
(d) payment by any Guarantor of a portion, but not all, of the Guaranteed Obligations shall in no way limit, affect, modify or abridge any Guarantor’s liability for any portion of the Guaranteed Obligations which has not been paid. Without limiting the generality of the foregoing, if the Lender is awarded a judgment in any suit brought to enforce any Guarantor’s covenant to pay a portion of the Guaranteed Obligations, such judgment shall not be deemed to release such Guarantor from its covenant to pay the portion of the Guaranteed Obligations that is not the subject of such suit, and such judgment shall not, except to the extent satisfied by such Guarantor, limit, affect, modify or abridge any other Guarantor’s liability hereunder in respect of the Guaranteed Obligations;
 
(e) the Lender, upon such terms as it deems appropriate, without notice or demand and without affecting the validity or enforceability hereof or giving rise to any reduction, limitation, impairment, discharge or termination of any Guarantor’s liability hereunder, from time to time may (i) renew, extend, accelerate, increase the rate of interest on, or otherwise change the time, place, manner or terms of payment of the Guaranteed Obligations; (ii) settle, compromise, release or discharge, or accept or refuse any offer of performance with respect to, or substitutions for, the Guaranteed Obligations or any agreement relating thereto and/or subordinate the payment of the same to the payment of any other obligations; (iii) request and accept other guaranties of the Guaranteed Obligations and take and hold security for the payment hereof or the Guaranteed Obligations; and (iv) exercise any other rights available to it under the Loan Documents; and
 
(f) this Guaranty and the obligations of Guarantors hereunder shall be valid and enforceable and shall not be subject to any reduction, limitation, impairment, discharge or termination for any reason (other than payment in full of the Guaranteed Obligations), including the occurrence of any of the following, whether or not any Guarantor shall have had notice or knowledge of any of them: (i) any failure or omission to assert or enforce or agreement or election not to assert or enforce, or the stay or enjoining, by order of court, by operation of law or otherwise, of the exercise or enforcement of, any claim or demand or any right, power or remedy (whether arising under the Loan Documents, at law, in equity or otherwise) with respect to the Guaranteed Obligations or any agreement relating thereto, or with respect to any other guaranty of the payment of the Guaranteed Obligations; (ii) any rescission, waiver, amendment or modification of, or any consent to departure from, any of the terms or provisions (including provisions relating to Events of Default) hereof, any of the other Loan Documents or any agreement or instrument executed pursuant thereto, or of any other guaranty for the Guaranteed Obligations, in each case whether or not in accordance with the terms hereof or such Loan Document or any agreement relating to such other guaranty; (iii) the Guaranteed Obligations, or any agreement relating thereto, at any time being found to be illegal, invalid or unenforceable in any respect; (iv) the application of payments received from any source (other than payments received pursuant to the other Loan Documents) to the payment of indebtedness other than the Guaranteed Obligations, even though the Lender might have elected to apply such payment to any part or all of the Guaranteed Obligations; (v) the Lender’s consent to the change, reorganization or termination of the corporate structure or existence of Borrower or any of its Subsidiaries and to any corresponding restructuring of the Guaranteed Obligations; (vi) any defenses, set offs or counterclaims which Borrower may allege or assert against the Lender in respect of the Guaranteed Obligations, including failure of consideration, breach of warranty, payment, statute of


B-16

frauds, statute of limitations, accord and satisfaction and usury; and (vii) any other act or thing or omission, or delay to do any other act or thing, which may or might in any manner or to any extent vary the risk of any Guarantor as an obligor in respect of the Guaranteed Obligations.
 
Section 7.04.  Waivers by Guarantors.  Each Guarantor hereby waives, for the benefit of the Lender: (a) any right to require the Lender, as a condition of payment or performance by such Guarantor, to (i) proceed against Borrower, any other guarantor (including any other Guarantor) of the Guaranteed Obligations or any other Person, (ii) proceed against or exhaust any security held from Borrower, any such other guarantor or any other Person, (iii) proceed against or have resort to any balance of any deposit account or credit on the books of the Lender in favor of Borrower or any other Person, or (iv) pursue any other remedy in the power of the Lender whatsoever; (b) any defense arising by reason of the incapacity, lack of authority or any disability or other defense of Borrower or any other Guarantor including any defense based on or arising out of the lack of validity or the unenforceability of the Guaranteed Obligations or any agreement or instrument relating thereto or by reason of the cessation of the liability of Borrower or any other Guarantor from any cause other than payment in full of the Guaranteed Obligations; (c) any defense based upon any statute or rule of law which provides that the obligation of a surety must be neither larger in amount nor in other respects more burdensome than that of the principal; (d) any defense based upon the Lender’s errors or omissions in the administration of the Guaranteed Obligations, except behavior which amounts to bad faith; (e) (i) any principles or provisions of law, statutory or otherwise, which are or might be in conflict with the terms hereof and any legal or equitable discharge of such Guarantor’s obligations hereunder, (ii) the benefit of any statute of limitations affecting such Guarantor’s liability hereunder or the enforcement hereof, and (iii) any rights to set offs, recoupments and counterclaims; (f) notices, demands, presentments, protests, notices of protest, notices of dishonor and notices of any action or inaction, including acceptance hereof, notices of default hereunder, notices of any renewal, extension or modification of the Guaranteed Obligations or any agreement related thereto, notices of any extension of credit to Borrower and notices of any of the matters referred to in Section 7.03 and any right to consent to any thereof; and (g) any defenses or benefits that may be derived from or afforded by law which limit the liability of or exonerate guarantors or sureties, or which may conflict with the terms hereof.
 
Section 7.05.  Guarantors’ Rights of Subrogation, Contribution, Etc.  Until the Guaranteed Obligations shall have been indefeasibly paid in full and the Commitments shall have terminated, each Guarantor hereby waives any claim, right or remedy, direct or indirect, that such Guarantor now has or may hereafter have against Borrower or any other Guarantor or any of its assets in connection with this Guaranty or the performance by such Guarantor of its obligations hereunder, in each case whether such claim, right or remedy arises in equity, under contract, by statute, under common law or otherwise and including (a) any right of subrogation, reimbursement or indemnification that such Guarantor now has or may hereafter have against Borrower with respect to the Guaranteed Obligations, and (b) any right to enforce, or to participate in, any claim, right or remedy that the Lender now has or may hereafter have against Borrower. In addition, until the Guaranteed Obligations shall have been indefeasibly paid in full and the Commitments shall have terminated, each Guarantor shall withhold exercise of any right of contribution such Guarantor may have against any other guarantor (including any other Guarantor) of the Guaranteed Obligations. Each Guarantor further agrees that, to the extent the waiver or agreement to withhold the exercise of its rights of subrogation, reimbursement, indemnification and contribution as set forth herein is found by a court of competent jurisdiction to be void or voidable for any reason, any rights of subrogation, reimbursement or indemnification such Guarantor may have against Borrower, and any rights of contribution such Guarantor may have against any such other guarantor, shall be junior and subordinate to any rights the Lender may have against Borrower to any right the Lender may have against such other guarantor. If any amount shall be paid to any Guarantor on account of any such subrogation, reimbursement, indemnification or contribution rights at any time when all Guaranteed Obligations shall not have been finally and indefeasibly paid in full, such amount shall be held in trust for the Lender and shall forthwith be paid over to the Lender to be credited and applied against the Guaranteed Obligations, whether matured or unmatured, in accordance with the terms hereof.
 
Section 7.06.  Subordination of Other Obligations.  Any Indebtedness of Borrower or any Guarantor now or hereafter held by any Guarantor (the “Obligee Guarantor”) is hereby subordinated in right of payment to the Guaranteed Obligations, and any such Indebtedness collected or received by the Obligee Guarantor after an Event of Default has occurred and is continuing shall be held in trust for the Lender and shall forthwith be paid over to the


B-17


Table of Contents

Lender to be credited and applied against the Guaranteed Obligations but without affecting, impairing or limiting in any manner the liability of the Obligee Guarantor under any other provision hereof.
 
Section 7.07.  Continuing Guaranty.  This Guaranty is a continuing guaranty and shall remain in effect until all of the Guaranteed Obligations shall have been paid in full and the Commitments shall have terminated. Each Guarantor hereby irrevocably waives any right to revoke this Guaranty as to future transactions giving rise to any Guaranteed Obligations.
 
Section 7.08.  Authority of Guarantors or Borrower.  It is not necessary for the Lender to inquire into the capacity or powers of any Guarantor or Borrower or the officers, directors or any agents acting or purporting to act on behalf of any of them.
 
Section 7.09.  Financial Condition of Borrower.  Any Loan may be made to Borrower or continued from time to time without notice to or authorization from any Guarantor regardless of the financial or other condition of Borrower at the time of any such grant or continuation. The Lender shall have no obligation to disclose or discuss with any Guarantor its assessment, or any Guarantor’s assessment, of the financial condition of Borrower. Each Guarantor has adequate means to obtain information from Borrower on a continuing basis concerning the financial condition of Borrower and its ability to perform its obligations under the Loan Documents and each Guarantor assumes the responsibility for being and keeping informed of the financial condition of Borrower and of all circumstances bearing upon the risk of nonpayment of the Guaranteed Obligations. Each Guarantor hereby waives and relinquishes any duty on the part of the Lender to disclose any matter, fact or thing relating to the business, operations or conditions of Borrower now known or hereafter known by the Lender.
 
Section 7.10.  Bankruptcy, Etc.  (a) So long as any Guaranteed Obligations remain outstanding, no Guarantor shall, without the prior written consent of the Lender, commence or join with any other Person in commencing any bankruptcy, reorganization or insolvency case or proceeding of or against Borrower or any other Guarantor. The obligations of Guarantors hereunder shall not be reduced, limited, impaired, discharged, deferred, suspended or terminated by any case or proceeding, voluntary or involuntary, involving the bankruptcy, insolvency, receivership, reorganization, liquidation or arrangement of Borrower or any other Guarantor or by any defense which Borrower or any other Guarantor may have by reason of the order, decree or decision of any court or administrative body resulting from any such proceeding.
 
(b) Each Guarantor acknowledges and agrees that any interest on any portion of the Guaranteed Obligations which accrues after the commencement of any case or proceeding referred to in clause (a) above (or, if interest on any portion of the Guaranteed Obligations ceases to accrue by operation of law by reason of the commencement of such case or proceeding, such interest as would have accrued on such portion of the Guaranteed Obligations if such case or proceeding had not been commenced) shall be included in the Guaranteed Obligations because it is the intention of Guarantors and the Lender that the Guaranteed Obligations which are guaranteed by Guarantors pursuant hereto should be determined without regard to any rule of law or order which may relieve Borrower of any portion of such Guaranteed Obligations. Guarantors will permit any trustee in bankruptcy, receiver, debtor in possession, assignee for the benefit of creditors or similar Person to pay the Lender, or allow the claim of the Lender in respect of, any such interest accruing after the date on which such case or proceeding is commenced.
 
(c) In the event that all or any portion of the Guaranteed Obligations are paid by Borrower, the obligations of Guarantors hereunder shall continue and remain in full force and effect or be reinstated, as the case may be, in the event that all or any part of such payment(s) are rescinded or recovered directly or indirectly from the Lender as a preference, fraudulent transfer or otherwise, and any such payments which are so rescinded or recovered shall constitute Guaranteed Obligations for all purposes hereunder.
 
ARTICLE VIII.

Section 9.03.  Binding Effect.  This Agreement shall become effective when it shall have been executed by each of the parties hereto and thereto and when the Lender shall have received counterparts hereof and thereof which, when taken together, bear the signatures of each of the other parties hereto and thereto.

B-21


Table of Contents

Section 9.04(b)) and principal and interest shall only be paid to such persons recorded in the register. The register is intended to function as a “book entry” system within the meaning of sections 5f.103-1(c)(1)(ii) and 5f.103-1(c)(2) of the Treasury Regulations (and any successor provisions).
 
Section 9.05.  Right of Setoff.  If an Event of Default shall have occurred and be continuing, the Lender is hereby authorized at any time and from time to time, except to the extent prohibited by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by the Lender to or for the credit or the account of the Borrower against any of and all the obligations of the Borrower now or hereafter existing under this Agreement and other Loan Documents held by the Lender, irrespective of whether or not the Lender shall have made any demand under this Agreement or such other Loan Document and although such obligations may be unmatured.

Section 9.07.  Waivers; Amendment.  (a) No failure or delay of the Lender in exercising any power or right hereunder or under any other Loan Document shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Lender hereunder and under the other Loan Documents are cumulative and are not exclusive of any rights or remedies that it would otherwise have. No waiver of any provision of this Agreement or any other Loan Document or consent to any departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) below, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given.

Table of Contents

CONNECTION WITH THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS.

The parties shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.
 
Section 9.12.  Counterparts.  This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original but all of which when taken together shall constitute a single contract, and shall become effective as provided in Section 9.03.

Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.
 
(a) Each party hereto hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement in any New York State or Federal court sitting in the Borough of Manhattan, New York, New York. Each of the parties hereto hereby irrevocably waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court.
 
(b) Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 9.01. Nothing in this Agreement will affect the right of any party to this Agreement to serve process in any other manner permitted by law.
 
Section 9.15.  No Fiduciary Duty.  The Lender and its Affiliates (collectively, solely for purposes of this paragraph, the “Lender”), may have economic interests that conflict with those of the Borrower. The Borrower agrees that nothing in the Loan Documents or otherwise will be deemed to create an advisory, fiduciary or agency relationship or fiduciary or other implied duty between the Lender and the Borrower, its stockholders or its affiliates. The Borrower acknowledge and agree that (i) the transactions contemplated by the Loan Documents are arm’s-length commercial transactions between the Lender, on the one hand, and the Borrower, on the other, (ii) in connection therewith and with the process leading to such transaction the Lender is acting solely as a principal and not the agent or fiduciary of the Borrower, its management, stockholders, creditors or any other Person, (iii) the

The Borrower further acknowledges and agrees that it is responsible for making its own independent judgment with respect to such transactions and the process leading thereto.

Section 9.16.  Payments Set Aside.  To the extent that any payment by or on behalf of the Borrower is made to the Lender, or the Lender exercises its right of setoff, and such payment or the proceeds of such setoff or any part thereof is subsequently invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by the Lender in its discretion) to be repaid to a trustee, receiver or any other party, in connection with any proceeding under any bankruptcy or insolvency law or otherwise, then to the extent of such recovery, the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such setoff had not occurred.

Upon filing a Resale Shelf Registration Statement, the Company will, if applicable, use its commercially reasonable efforts to keep such Resale Shelf Registration Statement effective with the SEC for nine months following the date of the initial effectiveness of the Resale Shelf Registration Statement; provided that such nine month period shall be extended by any period or periods of time during which the Resale Registration Statement (taken together with any Subsequent Shelf Registration) is unavailable for sales of Registrable Securities, whether as provided in Section 4.1.2, Section 4.5 or otherwise (such nine month period, as extended, the “Resale Effectiveness Period”).
 
4.1.2  If any Resale Shelf Registration Statement or subsequent Registration Statement (a “Subsequent Shelf Registration”) ceases to be effective under the Securities Act for any reason at any time within the Resale Effectiveness Period, including the expiration thereof, the Company shall use its commercially reasonable efforts to cause such Resale Shelf Registration Statement or Subsequent Shelf Registration, respectively, to again become effective under the Securities Act (including obtaining the prompt withdrawal of any order suspending the effectiveness of such Resale Shelf Registration Statement), and in any event shall within thirty (30) days of such cessation of effectiveness, amend such Resale Shelf Registration Statement or Subsequent Shelf Registration, respectively, in a manner reasonably expected to obtain the withdrawal of any order suspending the effectiveness of

such Resale Shelf Registration Statement or Subsequent Shelf Registration, respectively, or file an additional registration statement providing for the registration, and the sale on a continuous or delayed basis, of all of the Registrable Securities pursuant to Rule 415 under the Securities Act; provided that such Subsequent Shelf Registration will not provide for the registration, and the sale on a continuous or delayed basis, of any Common Stock other than the Registrable Securities. If a Subsequent Shelf Registration is filed, the Company shall use its commercially reasonable efforts to (x) cause such Subsequent Shelf Registration to become effective under the Securities Act as soon as reasonably practicable after such filing and (y) keep such Subsequent Shelf Registration (or another Subsequent Shelf Registration) continuously effective with the SEC at all times during the Resale Effectiveness Period. Any such Subsequent Shelf Registration shall be a registration statement on Form S-3 to the extent that the Company is eligible to use such form. For the avoidance of doubt, the Company shall not be required to maintain a Resale Shelf Registration Statement or Subsequent Shelf Registration after the end of the Resale Effectiveness Period.
 
4.1.3  If for any reason the Company is unable to qualify as a registrant to register the Registrable Securities on Form S-3 or any equivalent form or forms or any similar registration in accordance with Section 4.1.1 or Section 4.1.2, as applicable, the Company shall use commercially reasonable efforts to file a registration statement on Form S-1 or any equivalent form or forms within thirty (30) days of such failure to qualify in order to provide for the registration of such Registrable Securities for resale by the Investor in accordance with any reasonable method of distribution elected by the Investor.
 
4.1.4  If the Investor intends that any Registrable Securities covered by any registration pursuant to Section 4.1 shall be distributed by means of an underwritten offering, the Investor will so advise the Company. In such event, the managing underwriter to administer the offering will be chosen by the Investor, subject to the prior written consent of the Company, such consent not to be unreasonably withheld, conditioned or delayed. Unless otherwise mutually agreed by the Company and the Investor, the Company and the Investor shall enter into an underwriting agreement in such reasonable and customary form as shall have been negotiated and agreed to by the Company with the underwriter or underwriters selected for such underwriting. If the Investor disapproves of the terms of the underwriting, the Investor may promptly elect to withdraw therefrom by written notice to the Company and the managing underwriter.
 
4.1.5  If the managing underwriter in any underwritten offering pursuant to this Section 4.1, advises the Company that in its reasonable opinion the number of securities requested by the Investor to be included in such distribution exceeds the number which can be sold without adversely affecting the marketability of such offering (including an adverse effect on the per share offering price), the Investor will include in such distribution only such number of securities that in the reasonable opinion of such underwriter can be sold without adversely affecting the marketability of the offering (including an adverse effect on the per share offering price).
 
4.1.6  Notwithstanding the foregoing, if the Company shall furnish to the Investor a certificate signed by the Chief Executive Officer of the Company stating that in the good faith judgment of the Board it would be detrimental to the Company and its stockholders for such Resale Shelf Registration Statement to be filed, the Company shall have the right to defer such filing for a period of not more than sixty (60) days after receipt of the request by the Investor; provided, however, that the Company shall not register any securities for the account of itself or any other stockholder during such sixty (60) day period.
 
4.1.7  In addition, the Company shall not be obligated to effect or to take any action to effect, any registration pursuant to this Section 4.1 after the Company has effected one (1) registration pursuant to this Section 4.1; provided, however, that such registration has been declared or ordered effective and has been available for sales of Registrable Securities for the entire Resale Effectiveness Period.
 
4.2  Piggyback Registrations
 
4.2.1  Whenever the Company proposes to register any of its Common Stock in connection with an underwritten public offering of such securities solely for cash, other than a registration on Form S-4 or Form S-8 (or any successor form), and the registration form to be filed may be used for the registration or qualification for distribution of Registrable Securities by the Company, the Company will give prompt written notice to the Investor of its intention to effect such a registration (but in no event less than ten (10) Business Days prior to the anticipated


C-4


Table of Contents

filing date) and, subject to Section 4.2.3, will include in such registration all Registrable Securities with respect to which the Company has received written requests for inclusion therein from the Investor within ten (10) Business Days after the date of the Company’s notice (a “Piggyback Registration Statement”). The Investor may withdraw its Registrable Securities from such Piggyback Registration Statement by giving prompt written notice to the Company and the managing underwriter, if any, on or before the fifth (5th) Business Day prior to the planned effective date of such Piggyback Registration Statement. The Company may terminate or withdraw any registration under this Section 4.2.1 prior to the effectiveness of such registration, whether or not the Investor has elected to include Registrable Securities in such registration.
 
4.2.2  The right of the Investor to registration pursuant to this Section 4.2 will be conditioned upon the Investor’s participation in the underwriting and the inclusion of the Investor’s Registrable Securities in the underwriting, and the Company and the Investor will (together with any other Persons distributing their securities through such underwriting) enter into an underwriting agreement (including all reasonable and customary questionnaires, powers of attorney, indemnities, lock-up letters and other documents required under the terms of such underwriting agreement) in such reasonable and customary form as shall have been negotiated and agreed to by the Company with the underwriter or underwriters selected for such underwriting by the Company. If the Investor disapproves of the terms of the underwriting, the Investor may elect to withdraw therefrom by written notice to the Company and the managing underwriter.
 
4.2.3 If the managing underwriter in any underwritten offering pursuant to a Piggyback Registration Statement advises the Company that in its sole and reasonable opinion the number of securities requested to be included in such registration exceeds the number which can be sold without adversely affecting the marketability of such offering (including an adverse effect on the per share offering price), the Company will include in such registration only such number of securities that in the reasonable opinion of such underwriter can be sold without adversely affecting the marketability of the offering (including an adverse effect on the per share offering price), which securities will be so included in the following order of priority: (i) first, the securities the Company proposes to sell and (ii) second, the Registrable Securities of the Investor and any other securities of the Company that have been requested by other holders of Common Stock having registration rights to be so included, on a pro rata basis, up to the maximum number of securities the managing underwriter advises the Company may be sold without adversely affecting the marketability of such offering.
 
4.3  Registration Procedures
 
Whenever any Registrable Securities are to be registered pursuant to Section 4.1, the Company will use its commercially reasonable efforts to effect the registration and sale of such Registrable Securities as soon as reasonably practicable in accordance with the intended method of disposition thereof and pursuant thereto. The Company shall, without limitation of its other obligations set forth in this Agreement:

net proceeds actually received by the Investor from the sale of Registrable Securities included in such registration exceeds (y) the amount of any other losses, expenses, settlements, damages, claims and liabilities that the Investor has been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission or violation. The indemnity agreement contained in this Section 5.1.2 shall not apply to amounts paid in settlement of any loss, claim, damage, liability or action if such settlement is effected without the consent of the Investor (which consent shall not be unreasonably withheld, conditioned or delayed), nor shall the Investor be liable to any Investor Indemnified Party for any such loss, claim, damage, liability or action where such untrue statement or alleged untrue statement or omission or alleged omission was corrected in a final or amended prospectus prior to the confirmation of the sale of the Registrable Securities to the person asserting any such loss, claim, damage or liability, and the Company or the underwriters failed to deliver a copy of the final or amended prospectus at or prior to the confirmation of the sale of the Registrable Securities to the person asserting any such loss, claim, damage or liability in any case in which such delivery is required by the Securities Act.
 
5.1.3 Each party entitled to indemnification under this Section 5 (the “Indemnified Party”) shall give written notice to the party required to provide indemnification (the “Indemnifying Party”) promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to participate or to assume the defense of any such claim or any litigation resulting therefrom, provided, however, that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party (whose approval shall not unreasonably be withheld, conditioned or delayed), and the Indemnified Party may participate in such defense at such party’s expense; provided, further, however, that an Indemnified Party (together with all other Indemnified Parties which may be represented without conflict by one counsel) shall have the right to retain one separate counsel, with the reasonable fees and expenses to be paid by the Indemnifying Party, if representation of such Indemnified Party by the counsel retained by the Indemnifying Party would be inappropriate due to conflicting interests between such Indemnified Party and any other party represented by such counsel in such proceeding. The failure of any Indemnified Party to give notice as provided herein shall relieve the Indemnifying Party of its obligations under this Section 5 only to the extent that the failure to give such notice is materially prejudicial or harmful to an Indemnifying Party’s ability to defend such action. No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the consent of each Indemnified Party (which consent shall not be unreasonably withheld, conditioned or delayed), consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation. The indemnity agreements contained in this Section 5 shall not apply to amounts paid in settlement of any loss, claim, damage, liability or action if such settlement is effected without the consent of the Indemnifying Party, which consent shall not be unreasonably withheld, conditioned or delayed. The indemnification set forth in this Section 5 shall be in addition to any other indemnification rights or agreements that an Indemnified Party may have.
 
5.1.4  If the indemnification provided for in this Section 5 is held by a court of competent jurisdiction to be unavailable to an Indemnified Party, other than pursuant to its terms, with respect to any claim, loss, damage, liability or action referred to therein, then, subject to the limitations contained in the last sentence of this Section 5.1.4, the Indemnifying Party, in lieu of indemnifying such Indemnified Party hereunder, shall contribute to the amount paid or payable by such Indemnified Party as a result of such claim, loss, damage, liability or action in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party on the one hand and the Indemnified Party on the other in connection with the actions that resulted in such claims, loss, damage, liability or action, as well as any other relevant equitable considerations. The relative fault of the Indemnifying Party and of the Indemnified Party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact related to information supplied by the Indemnifying Party or by the Indemnified Party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Investor agree that it would not be just and equitable if contribution pursuant to this Section 5.1.4 were based solely upon the number of entities from whom contribution was requested or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 5.1.4. In no event shall the Investor’s contribution obligation under this Section 5.1.4 exceed (i) the amount by which the net proceeds actually received by the Investor from the sale of Registrable Securities included in such registration exceeds (ii) the amount of any other

losses, expenses, settlements, damages, claims and liabilities that the Investor has been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission or violation. No person guilty of fraudulent misrepresentation (within the meaning of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.
 
5.1.5  Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in an underwriting agreement entered into in connection with an underwritten public offering are in conflict with the foregoing provisions, the provisions in such underwriting agreement shall control.

SUPPORT AGREEMENT
 
This SUPPORT AGREEMENT (the “Agreement”), dated as of February 12, 2009, is entered into by and between the undersigned stockholder (“Stockholder”) of HeartWare International, Inc., a Delaware corporation (the “Company”), and Thoratec Corporation, a California corporation (“Parent”).
 
WHEREAS, concurrently with the execution of this Agreement, the Company, Parent, Thomas Merger Sub I, Inc., a Delaware corporation and a wholly-owned subsidiary of Parent (“Merger Subsidiary”) and Thomas Merger Sub II, Inc., a Delaware corporation and a wholly-owned subsidiary of Parent (“Merger Subsidiary Two”), are entering into an Agreement and Plan of Merger (as the same may be amended from time to time, the “Merger Agreement”), providing for the merger of Merger Subsidiary with and into the Company (the “Merger”), with the Company continuing as the surviving corporation (the “Intermediate Surviving Corporation”) and the merger of the Intermediate Surviving Corporation with and into Merger Subsidiary Two, with Merger Subsidiary Two as the surviving corporation (the “Second Merger” and together with the Merger, the “Mergers”) pursuant to the terms and subject to the conditions set forth in the Merger Agreement;
 
WHEREAS, as a condition to its willingness to enter into the Merger Agreement, Parent has requested that Stockholder make certain representations, warranties, covenants and agreements with respect to the shares of common stock, par value $0.001 per share, of the Company (the “Common Stock”) and/or CHESS Depositary Interests representing shares of Common Stock (collectively, with the Common Stock, the “Shares”) beneficially owned by Stockholder and set forth opposite Stockholder’s name on Schedule A attached hereto (the “Stockholder Shares”); and
 
WHEREAS, in order to induce Parent to enter into the Merger Agreement, Stockholder is willing to make certain representations, warranties, covenants and agreements with respect to the Stockholder Shares as set forth herein;
 
NOW, THEREFORE, in consideration of the promises contained herein and for other good and valuable consideration, the receipt, sufficiency and adequacy of which is hereby acknowledged, the parties hereto agree as follows:
 
1.  Representations of Stockholder.  Stockholder represents and warrants to Parent that (a) Stockholder beneficially owns all of the Stockholder Shares free and clear of any lien, encumbrance or restriction and, except pursuant to this Agreement, there are no rights, agreements or commitments to which Stockholder is a party relating to the pledge, disposition or voting of any Shares, and there are no voting trusts or voting agreements with respect to the Stockholder Shares, (b) Stockholder does not beneficially own any Shares other than the Stockholder Shares and (c) Stockholder has full power and authority to enter into, execute and deliver this Agreement and to perform fully Stockholder’s obligations hereunder, and no permit, authorization, consent or approval from any Person is necessary therefor. Stockholder further represents and warrants to Parent that this Agreement has been duly executed and delivered by Stockholder and constitutes the legal, valid and binding obligation of Stockholder enforceable against Stockholder in accordance with its terms.
 
2.  Representations of Parent.  Parent represents and warrants to Stockholder that (a) Parent has full power and authority to enter into, execute and deliver this Agreement and to perform fully Parent’s obligations hereunder and no permit, authorization, consent or approval from any Person is necessary therefore and (b) this Agreement has been duly executed and delivered by Parent and constitutes the legal, valid and binding obligation of Parent enforceable against Parent in accordance with its terms.
 
3.  Agreement to Vote Shares.  From the date of this Agreement to the earliest to occur of (a) the date upon which the Merger Agreement is validly terminated, (b) the Effective Time of the Merger, (c) the date following receipt of the Company Stockholder Approval, (d) the date that any material amendment shall be made to the Merger Agreement (a “material amendment” shall mean any valid written amendment to the Merger Agreement reducing the consideration payable to Stockholder pursuant to the Merger Agreement and any other valid written amendment to the Merger Agreement that would materially delay the consummation of


D-1

the Merger) without the written consent of Stockholder and (e)(i) any amendment to the Articles of Incorporation or Bylaws (whether by merger, consolidation or otherwise) of Parent in any manner that would have a disparate effect on holders of Shares, as holders of Parent Stock at and following the Effective Time, relative to other holders of Parent Stock, and (ii) any amendment to the Articles of Incorporation of Parent to provide for any class of capital stock with rights to distributions or upon a liquidation (including upon a merger, consolidation, asset sale or similar transaction) that are superior to those of the Parent Stock, other than an amendment in connection with a shareholder rights plan, “poison pill” anti-takeover plan or other similar device (the earliest of such to occur being the “Voting Covenant Expiration Date”), Stockholder shall, and shall cause any holder of record of the Stockholder Shares or any New Shares (as defined in Section 9 hereof) to vote, or cause to be voted, the Stockholder Shares and any New Shares (i) in favor of (A) adoption of the Merger Agreement, (B) any other action in furtherance thereof; provided, that such action does not require a material amendment to the Merger Agreement to which Stockholder has not consented, and (C) any adjournment or postponement recommended by the Company with respect to any stockholder meeting concerning the Merger Agreement and the Mergers and (ii) against any Acquisition Proposal and any action or agreement that would result in a breach of any representation, warranty, covenant or obligation of the Company in the Merger Agreement or impair the ability of the Company to consummate the Merger. In addition, Stockholder agrees not to take, or commit or agree to take, any action inconsistent with the foregoing.
 
4.  No Voting Trusts or Other Arrangements.  Except as otherwise set forth herein, Stockholder agrees that Stockholder will not, and will not permit any entity under Stockholder’s control to, deposit any of the Stockholder Shares or any New Shares in a voting trust, grant any proxies or power of attorney with respect to the Stockholder Shares or any New Shares or subject any of the Stockholder Shares or any New Shares to any arrangement with respect to the voting of the Stockholder Shares or any New Shares other than agreements entered into with Parent.
 
 
5.  No Solicitations.  Stockholder agrees that Stockholder will not, and will not permit any entity under Stockholder’s control or any of its or their respective officers, directors, employees, agents or other representatives to, (a) solicit proxies or become a “participant” in a “solicitation”, as such terms are defined in Regulation 14A under the Securities and Exchange Act of 1934, as amended (the “Exchange Act”), in opposition to or competition with the consummation of the Mergers or otherwise encourage or assist any party in taking or planning any action which would reasonably be expected to compete with, impede, interfere with or attempt to discourage the consummation of the Mergers or inhibit the timely consummation of the Mergers in accordance with the terms of the Merger Agreement, (b) directly or indirectly encourage, initiate or cooperate in a stockholders’ vote or action by consent of the Company’s stockholders in opposition to or in competition with the consummation of the Mergers, (c) become a member of a “group” (as such term is used in Rule 13d-5 under the Exchange Act) with respect to any voting securities of the Company for the purpose of opposing or competing with the consummation of the Mergers or (d) unless required by applicable law, make any press release, public announcement or other non-confidential communication with respect to the business or affairs of the Company or Parent, including this Agreement and the Merger Agreement and the transactions contemplated hereby and thereby, without the prior written consent of Parent.
 
6.  Waiver of Appraisal and Dissenters’ Rights and Actions.  Stockholder hereby (a) waives and agrees not to exercise any rights of appraisal or rights to dissent from the Mergers that Stockholder may have and (b) agrees not to commence or participate in, and to take all actions necessary to opt out of any class in any class action with respect to, any claim, derivative or otherwise, against Parent, Merger Subsidiary, Merger Subsidiary Two, the Company or any of their respective successors relating to the negotiation, execution or delivery of this Agreement or the Merger Agreement or the consummation of the Mergers, including any claim (i) challenging the validity of or seeking to enjoin the operation of any provision of this Agreement or (ii) alleging a breach of any fiduciary duty of the Board of Directors of the Company in connection with the Merger Agreement or the transactions contemplated thereby.
 
7.  Stockholder Capacity.  Notwithstanding anything to the contrary set forth herein, Stockholder is entering into this Agreement solely in Stockholder’s capacity as the beneficial owner of the Stockholder Shares and New Shares, as applicable, and nothing in this Agreement shall prevent Stockholder from taking any action or omitting to take any action in Stockholder’s capacity as a member of the Board of Directors of the


D-2


Table of Contents

Company or any of its subsidiaries (or any committee thereof) or as an officer or employee of the Company or any of its subsidiaries, in either case as applicable or as may become applicable to Stockholder. If Stockholder is an officer of director of the Company, any action taken by Stockholder in Stockholder’s capacity as an officer or director of the Company (but, for the avoidance of doubt, excluding any action taken by Stockholder in Stockholder’s capacity as a holder or beneficial owner of any Shares) will not be deemed to constitute a breach of this Agreement, regardless of the circumstances related thereto.
 
8.  Transfer and Encumbrance.  During the period from the date hereof through the Voting Covenant Expiration Date, except as otherwise expressly contemplated by this Section 8, Stockholder agrees not to transfer, sell, offer, exchange, pledge or otherwise dispose of or encumber any of the Stockholder Shares or New Shares and not to enter into any contract, agreement or arrangement with respect to any of the foregoing, and any such transfer shall be null and void and of no effect. This Section 8 shall not prohibit a transfer of any Stockholder Shares or New Shares by Stockholder (a) to any member of Stockholder’s immediate family, or to a trust for the benefit of Stockholder or any member of Stockholder’s immediate family, (b) upon the death of Stockholder, or (c) to the extent required to pay taxes resulting from the vesting of any stock awards for Shares or the exercise of any stock options within 60 days prior to their expiration or (d) to the extent required to effect a net or cashless exercise of any stock option within 60 days prior to their expiration; provided, however, that a transfer referred to in this sentence, other than a transfer in accordance with the foregoing clause (c) or (d), shall be permitted only if, as a precondition to such transfer, the proposed transferee agrees in writing, reasonably satisfactory in form and substance to Parent, to be bound by the terms of this Agreement with respect to all of the Stockholder Shares or New Shares so transferred.
 
9.  Additional Purchases.  Stockholder agrees that (a) all Shares that Stockholder purchases, acquires the right to vote or share in the voting of, or otherwise acquires beneficial ownership of, including upon the exercise of options to purchase Shares, after the execution of this Agreement and (b) all Shares which Stockholder owns beneficially or of record but has not included as Stockholder Shares as of the date hereof for any reason (all such Shares collectively, “New Shares”), shall be subject to the terms of this Agreement to the same extent as if they constituted Stockholder Shares as of the date hereof.
 
10.  Specific Performance.  Each party hereto acknowledges that it will be impossible to measure in money the damage to the other party if a party hereto fails to comply with any of the obligations imposed by this Agreement, that every such obligation is material and that, in the event of any such failure, the other party will not have an adequate remedy at law or damages. Accordingly, each party hereto agrees that injunctive relief or other equitable remedy, in addition to remedies at law or damages, is the appropriate remedy for any such failure and will not oppose the granting of such relief on the basis that the other party has an adequate remedy at law. Each party hereto agrees that it will not seek, and agrees to waive any requirement for, the securing or posting of a bond in connection with any other party’s seeking or obtaining such equitable relief.
 
11.  Remedies.  All rights, powers and remedies provided under this Agreement or otherwise available in respect hereof at law or in equity shall be cumulative and not alternative, and the exercise of any such right, power or remedy by any party hereto shall not preclude the simultaneous or later exercise of any other such right, power or remedy by such party.
 
12.  Entire Agreement.  This Agreement supersedes all prior agreements, written or oral, among the parties hereto with respect to the subject matter hereof and contains the entire agreement among the parties with respect to the subject matter hereof.

(a) THIS AGREEMENT, AND ALL CLAIMS AND CAUSES OF ACTION ARISING OUT OF, BASED UPON, OR RELATED TO THIS AGREEMENT OR THE NEGOTIATION, EXECUTION OR PERFORMANCE HEREOF, SHALL BE DEEMED TO BE MADE IN AND IN ALL RESPECTS SHALL BE GOVERNED BY, AND CONSTRUED, INTERPRETED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF DELAWARE, WITHOUT REGARD TO CHOICE OR CONFLICT OF LAW PRINCIPLES THAT WOULD RESULT IN THE APPLICATION OF ANY LAWS OTHER THAN THE LAWS OF THE STATE OF DELAWARE. Any legal action, suit or proceeding arising out of, based upon or relating to this Agreement or the transactions contemplated hereby shall be brought solely in the Chancery Court of the State of Delaware and any state appellate court therefrom within the State of Delaware (or, if the Chancery Court of the State of Delaware declines to accept jurisdiction over a particular matter, any state or federal court within the State of Delaware and any direct appellate court therefrom). Each party hereby irrevocably submits to the exclusive jurisdiction of such courts in respect of any legal action, suit or proceeding arising out of, based upon or relating to this Agreement and the rights and obligations arising hereunder and agrees that it will not bring any action arising out of, based upon or related to this Agreement in any other court. Each party hereby irrevocably waives, and agrees not to assert as a defense, counterclaim or otherwise, in any legal action, suit or proceeding arising out of, based upon or relating to this Agreement, (i) any claim that it is not personally subject to the jurisdiction of the above named courts for any reason other than the failure to serve process in accordance with Section 13, (ii) any claim that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise), and (iii) to the fullest extent permitted by Applicable Law, any claim that (A) the suit, action or proceeding in such court is brought in an inconvenient forum, (B) the venue of such suit, action or proceeding is improper, or (C) this Agreement, or the subject mater hereof, may not be enforced in or by such courts. Each party agrees that notice or the service of process in any action, suit or proceeding arising out of, based upon or relating to this Agreement or the rights and obligations arising hereunder shall be properly served or delivered if delivered in the manner contemplated by Section 13.

SUPPORT AGREEMENT
 
This SUPPORT AGREEMENT (the “Agreement”), dated as of February 12, 2009, is entered into by and between the undersigned stockholder (“Stockholder”) of HeartWare International, Inc., a Delaware corporation (the “Company”), and Thoratec Corporation, a California corporation (“Parent”).
 
WHEREAS, concurrently with the execution of this Agreement, the Company, Parent, Thomas Merger Sub I, Inc., a Delaware corporation and a wholly-owned subsidiary of Parent (“Merger Subsidiary”) and Thomas Merger Sub II, Inc., a Delaware corporation and a wholly-owned subsidiary of Parent (“Merger Subsidiary Two”), are entering into an Agreement and Plan of Merger (as the same may be amended from time to time, the “Merger Agreement”), providing for the merger of Merger Subsidiary with and into the Company (the “Merger”), with the Company continuing as the surviving corporation (the “Intermediate Surviving Corporation”) and the merger of the Intermediate Surviving Corporation with and into Merger Subsidiary Two, with Merger Subsidiary Two as the surviving corporation (the “Second Merger” and together with the Merger, the “Mergers”) pursuant to the terms and subject to the conditions set forth in the Merger Agreement;
 
WHEREAS, as a condition to its willingness to enter into the Merger Agreement, Parent has requested that Stockholder make certain representations, warranties, covenants and agreements with respect to the shares of common stock, par value $0.001 per share, of the Company (the “Common Stock”) and/or CHESS Depositary Interests representing shares of Common Stock (collectively, with the Common Stock, the “Shares”) beneficially owned by Stockholder and set forth opposite Stockholder’s name on Schedule A attached hereto (the “Stockholder Shares”); and
 
WHEREAS, in order to induce Parent to enter into the Merger Agreement, Stockholder is willing to make certain representations, warranties, covenants and agreements with respect to the Stockholder Shares as set forth herein;
 
NOW, THEREFORE, in consideration of the promises contained herein and for other good and valuable consideration, the receipt, sufficiency and adequacy of which is hereby acknowledged, the parties hereto agree as follows:
 
1.  Representations of Stockholder.  Stockholder represents and warrants to Parent that (a) Stockholder beneficially owns all of the Stockholder Shares free and clear of any lien, encumbrance or restriction and, except pursuant to this Agreement, there are no rights, agreements or commitments to which Stockholder is a party relating to the pledge, disposition or voting of any Shares, and there are no voting trusts or voting agreements with respect to the Stockholder Shares, (b) Stockholder does not beneficially own any Shares other than the Stockholder Shares and (c) Stockholder has full power and authority to enter into, execute and deliver this Agreement and to perform fully Stockholder’s obligations hereunder, and no permit, authorization, consent or approval from any Person is necessary therefor. Stockholder further represents and warrants to Parent that this Agreement has been duly executed and delivered by Stockholder and constitutes the legal, valid and binding obligation of Stockholder enforceable against Stockholder in accordance with its terms.
 
2.  Representations of Parent.  Parent represents and warrants to Stockholder that (a) Parent has full power and authority to enter into, execute and deliver this Agreement and to perform fully Parent’s obligations hereunder and no permit, authorization, consent or approval from any Person is necessary therefore and (b) this Agreement has been duly executed and delivered by Parent and constitutes the legal, valid and binding obligation of Parent enforceable against Parent in accordance with its terms.
 
3.  Agreement to Vote Shares.  From the date of this Agreement to the earliest to occur of (a) the date upon which the Merger Agreement is validly terminated, (b) the Effective Time of the Merger, (c) the date following receipt of the Company Stockholder Approval, (d) the date that any material amendment shall be made to the Merger Agreement (a “material amendment” shall mean any valid written amendment to the Merger Agreement reducing the consideration payable to Stockholder pursuant to the Merger Agreement and any other valid written amendment to the Merger Agreement that would materially delay the consummation of


E-1


Table of Contents

the Merger) without the written consent of Stockholder and (e)(i) any amendment to the Articles of Incorporation or Bylaws (whether by merger, consolidation or otherwise) of Parent in any manner that would have a disparate effect on holders of Shares, as holders of Parent Stock at and following the Effective Time, relative to other holders of Parent Stock, and (ii) any amendment to the Articles of Incorporation of Parent to provide for any class of capital stock with rights to distributions or upon a liquidation (including upon a merger, consolidation, asset sale or similar transaction) that are superior to those of the Parent Stock, other than an amendment in connection with a shareholder rights plan, “poison pill” anti-takeover plan or other similar device (the earliest of such to occur being the “Voting Covenant Expiration Date”), Stockholder shall, and shall cause any holder of record of the Stockholder Shares or any New Shares (as defined in Section 9 hereof) to vote, or cause to be voted, the Stockholder Shares and any New Shares (i) in favor of (A) adoption of the Merger Agreement, (B) any other action in furtherance thereof; provided, that such action does not require a material amendment to the Merger Agreement to which Stockholder has not consented, and (C) any adjournment or postponement recommended by the Company with respect to any stockholder meeting concerning the Merger Agreement and the Mergers and (ii) against any Acquisition Proposal and any action or agreement that would result in a breach of any representation, warranty, covenant or obligation of the Company in the Merger Agreement or impair the ability of the Company to consummate the Merger. In addition, Stockholder agrees not to take, or commit or agree to take, any action inconsistent with the foregoing.
 
4.  No Voting Trusts or Other Arrangements.  Except as otherwise set forth herein, Stockholder agrees that Stockholder will not, and will not permit any entity under Stockholder’s control to, deposit any of the Stockholder Shares or any New Shares in a voting trust, grant any proxies or power of attorney with respect to the Stockholder Shares or any New Shares or subject any of the Stockholder Shares or any New Shares to any arrangement with respect to the voting of the Stockholder Shares or any New Shares other than agreements entered into with Parent.
 
5.  No Solicitations.  Stockholder agrees that Stockholder will not, and will not permit any entity under Stockholder’s control or any of its or their respective officers, directors, employees, agents or other representatives to, (a) solicit proxies or become a “participant” in a “solicitation”, as such terms are defined in Regulation 14A under the Securities and Exchange Act of 1934, as amended (the “Exchange Act”), in opposition to or competition with the consummation of the Mergers or otherwise encourage or assist any party in taking or planning any action which would reasonably be expected to compete with, impede, interfere with or attempt to discourage the consummation of the Mergers or inhibit the timely consummation of the Mergers in accordance with the terms of the Merger Agreement, (b) directly or indirectly encourage, initiate or cooperate in a stockholders’ vote or action by consent of the Company’s stockholders in opposition to or in competition with the consummation of the Mergers, (c) become a member of a “group” (as such term is used in Rule 13d-5 under the Exchange Act) with respect to any voting securities of the Company for the purpose of opposing or competing with the consummation of the Mergers or (d) unless required by applicable law, make any press release, public announcement or other non-confidential communication with respect to the business or affairs of the Company or Parent, including this Agreement and the Merger Agreement and the transactions contemplated hereby and thereby, without the prior written consent of Parent.
 
6.  Waiver of Appraisal and Dissenters’ Rights and Actions.  Stockholder hereby (a) waives and agrees not to exercise any rights of appraisal or rights to dissent from the Mergers that Stockholder may have and (b) agrees not to commence or participate in, and to take all actions necessary to opt out of any class in any class action with respect to, any claim, derivative or otherwise, against Parent, Merger Subsidiary, Merger Subsidiary Two, the Company or any of their respective successors relating to the negotiation, execution or delivery of this Agreement or the Merger Agreement or the consummation of the Mergers, including any claim (i) challenging the validity of or seeking to enjoin the operation of any provision of this Agreement or (ii) alleging a breach of any fiduciary duty of the Board of Directors of the Company in connection with the Merger Agreement or the transactions contemplated thereby.
 
7.  Stockholder Capacity.  Notwithstanding anything to the contrary set forth herein, Stockholder is entering into this Agreement solely in Stockholder’s capacity as the beneficial owner of the Stockholder Shares and New Shares, as applicable, and nothing in this Agreement shall prevent Stockholder from taking any action or omitting to take any action in Stockholder’s capacity as a member of the Board of Directors of the


E-2


Table of Contents

Company or any of its subsidiaries (or any committee thereof) or as an officer or employee of the Company or any of its subsidiaries, in either case as applicable or as may become applicable to Stockholder. If Stockholder is an officer of director of the Company, any action taken by Stockholder in Stockholder’s capacity as an officer or director of the Company (but, for the avoidance of doubt, excluding any action taken by Stockholder in Stockholder’s capacity as a holder or beneficial owner of any Shares) will not be deemed to constitute a breach of this Agreement, regardless of the circumstances related thereto.
 
8.  Transfer and Encumbrance.  During the period from the date hereof through the Voting Covenant Expiration Date, except as otherwise expressly contemplated by this Section 8, Stockholder agrees not to transfer, sell, offer, exchange, pledge or otherwise dispose of or encumber any of the Stockholder Shares or New Shares and not to enter into any contract, agreement or arrangement with respect to any of the foregoing, and any such transfer shall be null and void and of no effect. This Section 8 shall not prohibit a transfer of any Stockholder Shares or New Shares by Stockholder to any transferee; provided, however, that a transfer referred to in this sentence shall be permitted only if, as a precondition to such transfer, the proposed transferee agrees in writing, reasonably satisfactory in form and substance to Parent, to be bound by the terms of this Agreement with respect to all of the Stockholder Shares or New Shares so transferred; provided, further, however, that such transfer shall not be permitted unless (a) following such transfer of the Stockholder Shares or New Shares the proposed transferee would beneficially own, in the aggregate, less than five percent (5%) of the outstanding Shares and (b) the transferee agrees to limit its beneficial ownership to no more than five percent (5%) of the outstanding Shares through the Voting Covenant Expiration Date.
 
9.  Additional Purchases.  Stockholder agrees that (a) all Shares that Stockholder purchases, acquires the right to vote or share in the voting of, or otherwise acquires beneficial ownership of, including upon the exercise of options to purchase Shares, after the execution of this Agreement and (b) all Shares which Stockholder owns beneficially or of record but has not included as Stockholder Shares as of the date hereof for any reason (all such Shares collectively, “New Shares”), shall be subject to the terms of this Agreement to the same extent as if they constituted Stockholder Shares as of the date hereof.
 
10.  No Other Support Agreements.  Except as provided in Section 8 hereof or in a similar agreement with a director or executive officer of the Company, Parent agrees that it shall not enter into any agreement or arrangement with any Company Stockholder pursuant to which such Company Stockholder would agree to vote shares of Company Stock held by it in favor of the merger other than this Agreement and similar agreements with directors and executive officers of the Company.
 
11.  Specific Performance.  Each party hereto acknowledges that it will be impossible to measure in money the damage to the other party if a party hereto fails to comply with any of the obligations imposed by this Agreement, that every such obligation is material and that, in the event of any such failure, the other party will not have an adequate remedy at law or damages. Accordingly, each party hereto agrees that injunctive relief or other equitable remedy, in addition to remedies at law or damages, is the appropriate remedy for any such failure and will not oppose the granting of such relief on the basis that the other party has an adequate remedy at law. Each party hereto agrees that it will not seek, and agrees to waive any requirement for, the securing or posting of a bond in connection with any other party’s seeking or obtaining such equitable relief.
 
12.  Remedies.  All rights, powers and remedies provided under this Agreement or otherwise available in respect hereof at law or in equity shall be cumulative and not alternative, and the exercise of any such right, power or remedy by any party hereto shall not preclude the simultaneous or later exercise of any other such right, power or remedy by such party.
 
13.  Entire Agreement.  This Agreement and the Letter Agreement, dated February 12, 2009, between Stockholder and Parent supersede all prior agreements, written or oral, among the parties hereto with respect to the subject matter hereof and contains the entire agreement among the parties with respect to the subject matter hereof.
 
14.  Notices.  All notices hereunder shall be in writing and shall be deemed given when delivered personally, upon receipt of a transmission confirmation if sent by telecopy, electronic mail or like transmission or on the next business day when sent by Federal Express, Express Mail or other reputable overnight courier

(the “Company”) of the consideration to be paid to such holders in the proposed merger (the “Transaction”) of the Company with a wholly-owned subsidiary of Thoratec Corporation (the “Acquiror”). Pursuant to the Agreement and Plan of Merger, dated as of February 12, 2009 (the “Agreement”), by and among the Company, the Acquiror and its subsidiaries, Thomas Merger Sub I, Inc. and Thomas Merger Sub II, Inc., the Company will become a wholly-owned subsidiary of the Acquiror, and each outstanding share of Company Common Stock, other than shares of Company Common Stock held in treasury or owned by the Acquiror and its affiliates and Dissenting Shares (as defined in the Agreement), will be converted into the right to receive consideration per share equal to $14.30 in cash (the “Cash Consideration”) and 0.6054 shares (the “Stock Consideration”, and, together with the Cash Consideration, the “Consideration”) of the Acquiror’s common stock (the “Acquiror Common Stock”). We also understand that the Stock Consideration will be subject to adjustment (the “Adjustment”) as provided in the Agreement based on the Average Parent Stock Price (as defined in the Agreement).
 
In arriving at our opinion, we have (i) reviewed the Agreement; (ii) reviewed certain publicly available business and financial information concerning the Company and the Acquiror and the industries in which they operate; (iii) compared the proposed financial terms of the Transaction with the publicly available financial terms of certain transactions involving companies we deemed relevant and the consideration received for such companies; (iv) compared the financial and operating performance of the Company and the Acquiror with publicly available information concerning certain other companies we deemed relevant and reviewed the current and historical market prices of the Company Common Stock and the Acquiror Common Stock and certain publicly traded securities of such other companies; (v) reviewed certain internal financial analyses and forecasts prepared by or at the direction of the managements of the Company and the Acquiror relating to their respective businesses, as well as discussed the estimated amount and timing of the cost savings and related expenses and synergies expected by the managements of the Company and the Acquiror to result from the Transaction (the “Synergies”); and (vi) performed such other financial studies and analyses and considered such other information as we deemed appropriate for the purposes of this opinion.
 
In addition, we have held discussions with certain members of the management of the Company and the Acquiror with respect to certain aspects of the Transaction, and the past and current business operations of the Company and the Acquiror, the financial condition and future prospects and operations of the Company and the Acquiror, the effects of the Transaction on the financial condition and future prospects of the Company and the Acquiror, and certain other matters we believed necessary or appropriate to our inquiry.
 
In giving our opinion, we have relied upon and assumed the accuracy and completeness of all information that was publicly available or was furnished to or discussed with us by the Company and the Acquiror or otherwise reviewed by or for us, and we have not independently verified (nor have we assumed responsibility or liability for independently verifying) any such information or its accuracy or completeness. We have not conducted or been provided with any valuation or appraisal of any assets or liabilities, nor have we evaluated the solvency of the Company or the Acquiror under any state or federal laws relating to bankruptcy, insolvency or similar matters. In relying on financial analyses and forecasts provided to us or derived therefrom, including the Synergies, we have assumed that they have been reasonably prepared based on assumptions reflecting the best currently available

estimates and judgments by management as to the expected future results of operations and financial condition of the Company and the Acquiror to which such analyses or forecasts relate. We express no view as to such analyses or forecasts (including the Synergies) or the assumptions on which they were based. We have also assumed that the Transaction and the other transactions contemplated by the Agreement will have the tax consequences described in discussions with, and materials furnished to us by, representatives of the Company, and will be consummated as described in the Agreement. We have also assumed that the representations and warranties made by the Company and the Acquiror in the Agreement and the related agreements are and will be true and correct in all respects material to our analysis, and that the Adjustment will not result in any adjustment to the Stock Consideration that is material to our analysis. We are not legal, regulatory or tax experts and have relied on the assessments made by advisors to the Company with respect to such issues. We have further assumed that all material governmental, regulatory or other consents and approvals necessary for the consummation of the Transaction will be obtained without any adverse effect on the Company or the Acquiror or on the contemplated benefits of the Transaction.
 
Our opinion is necessarily based on economic, market and other conditions as in effect on, and the information made available to us as of, the date hereof. It should be understood that subsequent developments may affect this opinion and that we do not have any obligation to update, revise, or reaffirm this opinion. Our opinion is limited to the fairness, from a financial point of view, of the Consideration to be paid to the holders of the Company Common Stock in the proposed Transaction and we express no opinion as to the fairness of the Transaction to, or any consideration paid in connection therewith to, the holders of any other class of securities, creditors or other constituencies of the Company or as to the underlying decision by the Company to engage in the Transaction. Furthermore, we express no opinion with respect to the amount or nature of any compensation to any officers, directors, or employees of any party to the Transaction, or any class of such persons relative to the Consideration to be paid to the holders of the Company Common Stock in the Transaction or with respect to the fairness of any such compensation. We are expressing no opinion herein as to the price at which the Company Common Stock or the Acquiror Common Stock will trade at any future time.
 
We have acted as financial advisor to the Company with respect to the proposed Transaction and will receive a fee from the Company for our services if the proposed Transaction is consummated. In addition, the Company has agreed to indemnify us for certain liabilities arising out of our engagement. Please be advised that during the two years preceding the date of this letter, neither we nor our affiliates have had any other significant financial advisory or other significant commercial or investment banking relationships with the Company or the Acquiror. In the ordinary course of our businesses, we and our affiliates may actively trade the debt and equity securities of the Company or the Acquiror for our own account or for the accounts of customers and, accordingly, we may at any time hold long or short positions in such securities.
 
On the basis of and subject to the foregoing, it is our opinion as of the date hereof that the Consideration to be paid to the holders of the Company Common Stock in the proposed Transaction is fair, from a financial point of view, to such holders.
 
The issuance of this opinion has been approved by a fairness opinion committee of J.P. Morgan Securities Inc. This letter is provided to the Board of Directors of the Company in connection with and for the purposes of its evaluation of the Transaction. This opinion does not constitute a recommendation to any stockholder of the Company as to how such stockholder should vote with respect to the Transaction or any other matter. This opinion may not be disclosed, referred to, or communicated (in whole or in part) to any third party for any purpose whatsoever except with our prior written approval. This opinion may be reproduced in full in any proxy or information statement mailed to stockholders of the Company but may not otherwise be disclosed publicly in any manner without our prior written approval.
 
Very truly yours,

Annex G
 
DELAWARE GENERAL CORPORATION LAW
 
§ 262 APPRAISAL RIGHTS. — (a) Any stockholder of a corporation of this State who holds shares of stock on the date of the making of a demand pursuant to subsection (d) of this section with respect to such shares, who continuously holds such shares through the effective date of the merger or consolidation, who has otherwise complied with subsection (d) of this section and who has neither voted in favor of the merger or consolidation nor consented thereto in writing pursuant to § 228 of this title shall be entitled to an appraisal by the Court of Chancery of the fair value of the stockholder’s shares of stock under the circumstances described in subsections (b) and (c) of this section. As used in this section, the word “stockholder” means a holder of record of stock in a stock corporation and also a member of record of a nonstock corporation; the words “stock” and “share” mean and include what is ordinarily meant by those words and also membership or membership interest of a member of a nonstock corporation; and the words “depository receipt” mean a receipt or other instrument issued by a depository representing an interest in one or more shares, or fractions thereof, solely of stock of a corporation, which stock is deposited with the depository.
 
(b) Appraisal rights shall be available for the shares of any class or series of stock of a constituent corporation in a merger or consolidation to be effected pursuant to § 251 (other than a merger effected pursuant to § 251(g) of this title), § 252, § 254, § 257, § 258, § 263 or § 264 of this title:
 
(1) Provided, however, that no appraisal rights under this section shall be available for the shares of any class or series of stock, which stock, or depository receipts in respect thereof, at the record date fixed to determine the stockholders entitled to receive notice of and to vote at the meeting of stockholders to act upon the agreement of merger or consolidation, were either (i) listed on a national securities exchange or (ii) held of record by more than 2,000 holders; and further provided that no appraisal rights shall be available for any shares of stock of the constituent corporation surviving a merger if the merger did not require for its approval the vote of the stockholders of the surviving corporation as provided in subsection (f) of § 251 of this title.
 
(2) Notwithstanding paragraph (1) of this subsection, appraisal rights under this section shall be available for the shares of any class or series of stock of a constituent corporation if the holders thereof are required by the terms of an agreement of merger or consolidation pursuant to §§ 251, 252, 254, 257, 258, 263 and 264 of this title to accept for such stock anything except:
 
a. Shares of stock of the corporation surviving or resulting from such merger or consolidation, or depository receipts in respect thereof;
 
b. Shares of stock of any other corporation, or depository receipts in respect thereof, which shares of stock (or depository receipts in respect thereof) or depository receipts at the effective date of the merger or consolidation will be either listed on a national securities exchange or held of record by more than 2,000 holders;
 
c. Cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a. and b. of this paragraph; or
 
d. Any combination of the shares of stock, depository receipts and cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a., b. and c. of this paragraph.
 
(3) In the event all of the stock of a subsidiary Delaware corporation party to a merger effected under § 253 of this title is not owned by the parent corporation immediately prior to the merger, appraisal rights shall be available for the shares of the subsidiary Delaware corporation.
 
(c) Any corporation may provide in its certificate of incorporation that appraisal rights under this section shall be available for the shares of any class or series of its stock as a result of an amendment to its certificate of incorporation, any merger or consolidation in which the corporation is a constituent corporation or the sale of all or substantially all of the assets of the corporation. If the certificate of incorporation contains such a provision, the


G-1


Table of Contents

procedures of this section, including those set forth in subsections (d) and (e) of this section, shall apply as nearly as is practicable.
 
(d) Appraisal rights shall be perfected as follows:
 
(1) If a proposed merger or consolidation for which appraisal rights are provided under this section is to be submitted for approval at a meeting of stockholders, the corporation, not less than 20 days prior to the meeting, shall notify each of its stockholders who was such on the record date for such meeting with respect to shares for which appraisal rights are available pursuant to subsection (b) or (c) hereof that appraisal rights are available for any or all of the shares of the constituent corporations, and shall include in such notice a copy of this section. Each stockholder electing to demand the appraisal of such stockholder’s shares shall deliver to the corporation, before the taking of the vote on the merger or consolidation, a written demand for appraisal of such stockholder’s shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such stockholder’s shares. A proxy or vote against the merger or consolidation shall not constitute such a demand. A stockholder electing to take such action must do so by a separate written demand as herein provided. Within 10 days after the effective date of such merger or consolidation, the surviving or resulting corporation shall notify each stockholder of each constituent corporation who has complied with this subsection and has not voted in favor of or consented to the merger or consolidation of the date that the merger or consolidation has become effective; or
 
(2) If the merger or consolidation was approved pursuant to § 228 or § 253 of this title, then either a constituent corporation before the effective date of the merger or consolidation or the surviving or resulting corporation within 10 days thereafter shall notify each of the holders of any class or series of stock of such constituent corporation who are entitled to appraisal rights of the approval of the merger or consolidation and that appraisal rights are available for any or all shares of such class or series of stock of such constituent corporation, and shall include in such notice a copy of this section. Such notice may, and, if given on or after the effective date of the merger or consolidation, shall, also notify such stockholders of the effective date of the merger or consolidation. Any stockholder entitled to appraisal rights may, within 20 days after the date of mailing of such notice, demand in writing from the surviving or resulting corporation the appraisal of such holder’s shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such holder’s shares. If such notice did not notify stockholders of the effective date of the merger or consolidation, either (i) each such constituent corporation shall send a second notice before the effective date of the merger or consolidation notifying each of the holders of any class or series of stock of such constituent corporation that are entitled to appraisal rights of the effective date of the merger or consolidation or (ii) the surviving or resulting corporation shall send such a second notice to all such holders on or within 10 days after such effective date; provided, however, that if such second notice is sent more than 20 days following the sending of the first notice, such second notice need only be sent to each stockholder who is entitled to appraisal rights and who has demanded appraisal of such holder’s shares in accordance with this subsection. An affidavit of the secretary or assistant secretary or of the transfer agent of the corporation that is required to give either notice that such notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein. For purposes of determining the stockholders entitled to receive either notice, each constituent corporation may fix, in advance, a record date that shall be not more than 10 days prior to the date the notice is given, provided, that if the notice is given on or after the effective date of the merger or consolidation, the record date shall be such effective date. If no record date is fixed and the notice is given prior to the effective date, the record date shall be the close of business on the day next preceding the day on which the notice is given.
 
(e) Within 120 days after the effective date of the merger or consolidation, the surviving or resulting corporation or any stockholder who has complied with subsections (a) and (d) of this section hereof and who is otherwise entitled to appraisal rights, may commence an appraisal proceeding by filing a petition in the Court of Chancery demanding a determination of the value of the stock of all such stockholders. Notwithstanding the foregoing, at any time within 60 days after the effective date of the merger or consolidation, any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party shall have the right to withdraw such stockholder’s demand for appraisal and to accept the terms offered upon the merger or consolidation.

Table of Contents

Within 120 days after the effective date of the merger or consolidation, any stockholder who has complied with the requirements of subsections (a) and (d) of this section hereof, upon written request, shall be entitled to receive from the corporation surviving the merger or resulting from the consolidation a statement setting forth the aggregate number of shares not voted in favor of the merger or consolidation and with respect to which demands for appraisal have been received and the aggregate number of holders of such shares. Such written statement shall be mailed to the stockholder within 10 days after such stockholder’s written request for such a statement is received by the surviving or resulting corporation or within 10 days after expiration of the period for delivery of demands for appraisal under subsection (d) of this section hereof, whichever is later. Notwithstanding subsection (a) of this section, a person who is the beneficial owner of shares of such stock held either in a voting trust or by a nominee on behalf of such person may, in such person’s own name, file a petition or request from the corporation the statement described in this subsection.
 
(f) Upon the filing of any such petition by a stockholder, service of a copy thereof shall be made upon the surviving or resulting corporation, which shall within 20 days after such service file in the office of the Register in Chancery in which the petition was filed a duly verified list containing the names and addresses of all stockholders who have demanded payment for their shares and with whom agreements as to the value of their shares have not been reached by the surviving or resulting corporation. If the petition shall be filed by the surviving or resulting corporation, the petition shall be accompanied by such a duly verified list. The Register in Chancery, if so ordered by the Court, shall give notice of the time and place fixed for the hearing of such petition by registered or certified mail to the surviving or resulting corporation and to the stockholders shown on the list at the addresses therein stated. Such notice shall also be given by 1 or more publications at least 1 week before the day of the hearing, in a newspaper of general circulation published in the City of Wilmington, Delaware or such publication as the Court deems advisable. The forms of the notices by mail and by publication shall be approved by the Court, and the costs thereof shall be borne by the surviving or resulting corporation.
 
(g) At the hearing on such petition, the Court shall determine the stockholders who have complied with this section and who have become entitled to appraisal rights. The Court may require the stockholders who have demanded an appraisal for their shares and who hold stock represented by certificates to submit their certificates of stock to the Register in Chancery for notation thereon of the pendency of the appraisal proceedings; and if any stockholder fails to comply with such direction, the Court may dismiss the proceedings as to such stockholder.
 
(h) After the Court determines the stockholders entitled to an appraisal, the appraisal proceeding shall be conducted in accordance with the rules of the Court of Chancery, including any rules specifically governing appraisal proceedings. Through such proceeding the Court shall determine the fair value of the shares exclusive of any element of value arising from the accomplishment or expectation of the merger or consolidation, together with interest, if any, to be paid upon the amount determined to be the fair value. In determining such fair value, the Court shall take into account all relevant factors. Unless the Court in its discretion determines otherwise for good cause shown, interest from the effective date of the merger through the date of payment of the judgment shall be compounded quarterly and shall accrue at 5% over the Federal Reserve discount rate (including any surcharge) as established from time to time during the period between the effective date of the merger and the date of payment of the judgment. Upon application by the surviving or resulting corporation or by any stockholder entitled to participate in the appraisal proceeding, the Court may, in its discretion, proceed to trial upon the appraisal prior to the final determination of the stockholders entitled to an appraisal. Any stockholder whose name appears on the list filed by the surviving or resulting corporation pursuant to subsection (f) of this section and who has submitted such stockholder’s certificates of stock to the Register in Chancery, if such is required, may participate fully in all proceedings until it is finally determined that such stockholder is not entitled to appraisal rights under this section.
 
(i) The Court shall direct the payment of the fair value of the shares, together with interest, if any, by the surviving or resulting corporation to the stockholders entitled thereto. Payment shall be so made to each such stockholder, in the case of holders of uncertificated stock forthwith, and the case of holders of shares represented by certificates upon the surrender to the corporation of the certificates representing such stock. The Court’s decree may be enforced as other decrees in the Court of Chancery may be enforced, whether such surviving or resulting corporation be a corporation of this State or of any state.

Table of Contents

(j) The costs of the proceeding may be determined by the Court and taxed upon the parties as the Court deems equitable in the circumstances. Upon application of a stockholder, the Court may order all or a portion of the expenses incurred by any stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorney’s fees and the fees and expenses of experts, to be charged pro rata against the value of all the shares entitled to an appraisal.
 
(k) From and after the effective date of the merger or consolidation, no stockholder who has demanded appraisal rights as provided in subsection (d) of this section shall be entitled to vote such stock for any purpose or to receive payment of dividends or other distributions on the stock (except dividends or other distributions payable to stockholders of record at a date which is prior to the effective date of the merger or consolidation); provided, however, that if no petition for an appraisal shall be filed within the time provided in subsection (e) of this section, or if such stockholder shall deliver to the surviving or resulting corporation a written withdrawal of such stockholder’s demand for an appraisal and an acceptance of the merger or consolidation, either within 60 days after the effective date of the merger or consolidation as provided in subsection (e) of this section or thereafter with the written approval of the corporation, then the right of such stockholder to an appraisal shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery shall be dismissed as to any stockholder without the approval of the Court, and such approval may be conditioned upon such terms as the Court deems just; provided, however that this provision shall not affect the right of any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party to withdraw such stockholder’s demand for appraisal and to accept the terms offered upon the merger or consolidation within 60 days after the effective date of the merger or consolidation, as set forth in subsection (e) of this section.
 
(l) The shares of the surviving or resulting corporation to which the shares of such objecting stockholders would have been converted had they assented to the merger or consolidation shall have the status of authorized and unissued shares of the surviving or resulting corporation.

PART II
 
INFORMATION NOT REQUIRED IN PROSPECTUS
 
Item 20.   Indemnification of Directors and Officers
 
Section 317 of the California Corporations Code permits a corporation to indemnify any person who was or is a party or is threatened to be made a party to any proceeding (other than an action by or in the right of the corporation to procure a judgment in its favor) by reason of the fact that the person is or was an agent of the corporation, against expenses, judgments, fines, settlements and other amounts actually and reasonably incurred in connection with the proceeding if that person acted in good faith and in a manner the person reasonably believed to be in the best interests of the corporation and, in the case of a criminal proceeding, had no reasonable cause to believe the conduct of the person was unlawful. No indemnification may be made in the cases of:
 
  •  Intentional misconduct or knowing and culpable violation of law;
 
  •  Acts or omissions that a director believes to be contrary to the best interests of the corporation or its shareholders or that involve the absence of good faith on the part of the director;
 
  •  Receipt of an improper personal benefit;
 
  •  Acts or omissions that show reckless disregard for the director’s duty to the corporation or its shareholders, where the director in the ordinary course of performing a director’s duties should be aware of a risk of serious injury to the corporation or its shareholders;
 
  •  Acts or omissions that constitute an unexcused pattern of inattention that amounts to an abdication of the director’s duty to the corporation and its shareholders; or
 
  •  Liability for improper distributions, loans or guarantees.
 
Pursuant to Section 317 of the California Corporations Code, Thoratec has included in its by-laws provisions regarding the indemnification of officers and directors of Thoratec.
 
Section 29 of Thoratec’s By-laws, as amended, provides as follows:
 
(a) Right of Indemnity.  To the full extent permitted by law, this corporation shall indemnify its directors, officers, employees and other persons described in Section 317(a) of the California Corporations Code, including persons formerly occupying any such position, against all expenses, judgments, fines, settlements and other amounts actually and reasonably incurred by them in connection with any “proceeding”, as that term is used in such Section and including an action by or in the right of the corporation, by reason of the fact that such person is or was a person described by such Section. “Expenses”, as used in this By-law, shall have the same meaning as in Section 317(a) of the California Corporations Code.
 
(b) Approval of Indemnity.  Upon written request to the Board of Directors by any person seeking indemnification under Section 317(b) or Section 317(c) of the California Corporations Code, the Board shall promptly determine in accordance with Section 317(e) of the Code whether the applicable standard of conduct set forth in Section 317(b) or Section 317(c) has been met and, if so, the Board shall authorize indemnification. If the Board cannot authorize indemnification because the number of directors who are parties to the proceeding with respect to which indemnification is sought prevent the formation of a quorum of directors who are not parties to such proceeding, the Board shall promptly call a meeting of shareholders. At such meeting, the shareholders shall determine in accordance with Section 317(e) of the Code whether the applicable standard of conduct set forth in Section 317(b) or Section 317(c) has been met and, if so, the shareholders present at the meeting in person or by proxy shall authorize indemnification.
 
(c) Advancement of Expenses.  To the full extent permitted by law and except as is otherwise determined by the Board of Directors in the specific instance, expenses incurred by a person seeking indemnification under this By-law in defending any proceeding covered by this By-law shall be advanced by the corporation prior to the final disposition of the proceeding upon receipt by the corporation of an undertaking by

or on behalf of such person to repay such amount unless it shall ultimately be determined that such person is entitled to be indemnified by the corporation therefor.
 
Thoratec has also entered into agreements with certain of its officers and directors to indemnify such persons within the limits set forth by California law and Thoratec’s By-laws, as amended. Thoratec also maintains a limited amount of director and officer insurance. The indemnification provision in the By-laws, and the indemnity agreements entered into between Thoratec and its officers or directors, may be sufficiently broad to permit indemnification of the Registrant’s officers and directors for liability arising under the Securities Act.

Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and
 
(iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.
 
(2) The undersigned Registrant hereby undertakes that, for the purpose of determining any liability under the Securities Act of 1933, as amended, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
 
(3) The undersigned Registrant hereby undertakes to remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
 
(4) The undersigned Registrant hereby undertakes as follows: that prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the undersigned Registrant undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other Items of the applicable form.

(5) The undersigned Registrant hereby undertakes that, for the purpose of determining liability under the Securities Act of 1933 to any purchaser, if the Registrant is subject to Rule 430C, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.
 
(6) The Registrant undertakes that every prospectus (a) that is filed pursuant to paragraph (4) immediately preceding, or (b) that purports to meet the requirements of Section 10(a)(3) of the Securities Act of 1933, as amended, and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, as amended, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
 
(7) Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended, may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act of 1933, as amended, and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933, as amended, and will be governed by the final adjudication of such issue.
 
(8) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, as amended, each filing of the Registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934, as amended (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934, as amended) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
 
(9) The undersigned Registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11 or 13 of this Form, within one business day of receipt of such request, and to send the incorporated documents by first-class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.
 
(10) The undersigned Registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.
 
(11) The undersigned Registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following

communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:
 
(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;
 
(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;
 
(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and
 
(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.
