PROXY STATEMENT
 
 
ANNUAL MEETING OF STOCKHOLDERS
To Be Held June 3, 2009
 
GENERAL INFORMATION ABOUT THE ANNUAL MEETING AND VOTING
 
The Board of Directors (the “Board” or “Board of Directors”) of Patterson-UTI Energy, Inc., a Delaware corporation (“Patterson-UTI”), has made these proxy materials available to you on the Internet, or, upon your request has delivered printed versions of these materials to you by mail. Patterson-UTI is furnishing this proxy statement in connection with the solicitation by the Board of Directors of proxies to be voted at the 2009 annual meeting of stockholders of Patterson-UTI (the “Meeting”). The Meeting will be held Wednesday, June 3, 2009, at 10:00 a.m., local time, at the Hilton Houston North Hotel, 12400 Greenspoint Drive, Houston, Texas 77060, or at any adjournment thereof. The Notice of Internet Availability of Proxy Materials (the “Notice”) was mailed to each of Patterson-UTI’s stockholders (other than those who previously requested electronic delivery) entitled to vote at the Meeting on or about April 20, 2009.
 
Pursuant to the “notice and access” rules adopted by the Securities and Exchange Commission (the “SEC”), Patterson-UTI has elected to provide stockholders access to its proxy materials over the Internet. Accordingly, Patterson-UTI sent a Notice to all of its stockholders as of the record date. The Notice includes instructions on how to access Patterson-UTI’s proxy materials over the Internet and how to request a printed copy of these materials. In addition, by following the instructions in the Notice, stockholders may request to receive proxy materials in printed form by mail or electronically by email on an ongoing basis.
 
Choosing to receive your future proxy materials by email will save us the cost of printing and mailing documents to you and will help conserve natural resources. If you choose to receive future proxy materials by email, you will receive an email next year with instructions containing a link to those materials and a link to the proxy voting site. Your election to receive proxy materials by email will remain in effect until you terminate it.
 
If your shares are registered directly in your name with our transfer agent, Continental Stock Transfer & Trust Company, you are considered the “stockholder of record” with respect to those shares, and the Notice was sent directly to you.
 
If your shares are held in an account at a brokerage firm, bank, broker-dealer, or other similar organization, then you are the beneficial owner of shares held in “street name,” and the Notice was forwarded to you by that organization. As a beneficial owner, you have the right to direct that organization on how to vote the shares held in your account.
 
Whether you are a “stockholder of record” or hold your shares in “street name,” you may direct your vote without attending the Meeting in person.
 
If you are a stockholder of record, you may vote by Internet or by telephone by following the instructions on the Notice. If you request printed copies of the proxy materials by mail, you may also vote by signing and submitting your proxy card and returning by mail or by submitting your vote by telephone. You should sign your name exactly as it appears on the proxy card. If you are signing in a representative capacity (for example, as guardian, executor, trustee, custodian, attorney or officer of a corporation), you should indicate your name and title or capacity.
 
If you are the beneficial owner of shares held in street name, you may be eligible to vote your shares electronically over the Internet or by telephone by following the instructions on the Notice. If you request printed copies of the proxy materials by mail, you may also vote by signing the voter instruction card provided by your bank


Table of Contents

or broker and returning it by mail. If you provide specific voting instructions by mail, telephone or the Internet, your shares will be voted by your broker or nominee as you have directed.
 
Properly submitted proxies received either by mail, Internet, telephone or in person, in time to be counted for the Meeting will be voted as you have directed in your proxy, unless you revoke your proxy in the manner provided below. As to any matter for which you give no direction in your proxy, your shares will be voted as follows:
 
  •  “FOR” the election of all of the nominees to the Board of Directors;
 
  •  “FOR” the ratification of PricewaterhouseCoopers LLP as the independent registered public accounting firm of Patterson-UTI for the fiscal year ending December 31, 2009; and
 
  •  “FOR” or “AGAINST” any other proposals that may be properly submitted at the Meeting at the discretion of the persons named in the proxy.
 
If you are a stockholder of record, you may revoke your proxy before the proxy is voted by either:
 
  •  submitting a new proxy with a later date, including a proxy submitted by the Internet or by telephone, in time to be counted for the meeting;
 
  •  notifying the Secretary of Patterson-UTI in writing before the Meeting that you have revoked your proxy; or
 
  •  attending the Meeting and voting in person.
 
If your shares are held in street name, you must obtain a proxy executed in your favor from the stockholder of record (that is, your brokerage firm, bank, broker-dealer or similar organization) to be able to vote at the Meeting.
 
The Board of Directors is making this solicitation. Patterson-UTI’s officers and other employees, without compensation other than regular compensation, may solicit proxies by mail, email, the Internet, telephone, electronic means and personal interview. Patterson-UTI does not intend to retain a proxy solicitation firm to assist in the solicitation of proxies of stockholders, but may do so if circumstances warrant. Patterson-UTI will pay all costs associated with this solicitation.
 
SHARES OUTSTANDING AND VOTING RIGHTS
 
Only stockholders of record of Patterson-UTI’s common stock, $.01 par value per share (the “Common Stock”), at the close of business on April 6, 2009 are entitled to notice of and to vote at the Meeting or any adjournment or postponement thereof. At the close of business on April 6, 2009, there were 153,100,199 shares of Common Stock issued and outstanding. Holders of record of Common Stock on April 6, 2009 will be entitled to one vote per share on all matters to properly come before the Meeting. A list of stockholders entitled to notice of and to vote at the Meeting will be made available during regular business hours at the offices of Patterson-UTI Energy, Inc., 450 Gears Road, Suite 500, Houston, Texas 77067, from May 19, 2009 through June 2, 2009 and at the Meeting for examination by any stockholder for any purpose germane to the Meeting.
 
A quorum is necessary to transact business at the Meeting. A majority of the shares of Common Stock outstanding on April 6, 2009 will constitute a quorum. The shares held by each stockholder who attends the Meeting in person, signs and timely returns the form of proxy or properly votes using the Internet or telephone will be counted for purposes of determining the presence of a quorum at the Meeting.
 
PROPOSAL NO. 1
 
ELECTION OF DIRECTORS
 
Patterson-UTI’s bylaws provide that the number of members of the Board of Directors shall be fixed either by amendment to the bylaws or by resolution of the Board of Directors. Directors are elected to serve until the next annual meeting of stockholders and until their successors are elected and qualified. Patterson-UTI’s bylaws provide that the affirmative vote of a plurality of the votes cast at the meeting at which a quorum is present is required for the election of directors. Shares as to which a stockholder withholds authority to vote on the election of directors and shares as to which a broker indicates that it does not have discretionary authority to vote on the election of directors

  •  withhold authority to vote for one or more of the nominees, or
 
  •  withhold authority to vote for all of the nominees.
 
The Board of Directors recommends that you vote “FOR” all of the nominees.  Unless you give contrary instructions in your proxy, your proxy will be voted “FOR” the election of all of the nominees to the Board of Directors. If any nominee should become unable or unwilling to accept nomination or election, the person acting under the proxy will vote for the election of such other person as the Board of Directors may recommend. The Board has no reason, however, to believe that any of the nominees will be unable or unwilling to serve if elected.
 
There are no arrangements or understandings between any person and any of the directors pursuant to which such director was selected as a nominee for election at the Meeting. There are no family relationships among any of the directors or executive officers of Patterson-UTI.

Meetings and Committees of the Board of Directors
 
The Board of Directors met seven times during the year ended December 31, 2008. Each director attended, in person or by telephone, at least 75% of the aggregate of all meetings held by the Board and meetings of each committee on which such director served. A majority of the members of the Board of Directors are independent within the meaning of the NASDAQ Stock Market, Inc. (“NASDAQ”) listing standards. Specifically, the Board has determined that Messrs. Buckner, Huff, Hunt and Peak are independent within the meaning of the NASDAQ listing standards. In reaching this conclusion, the Board considered that Mr. Huff controls and manages two investment companies, which have interests in oilfield service portfolio companies that supply parts and equipment to Patterson-UTI in the ordinary course of their businesses consistent with customary terms in the industry. The Board has determined that these transactions are not material to such companies, Patterson-UTI or Mr. Huff and that such transactions do not affect Mr. Huff’s independence under applicable rules and regulations.
 
The Board of Directors has established four standing committees, an Executive Committee, an Audit Committee, a Compensation Committee and a Nominating and Corporate Governance Committee.
 
The Executive Committee, which currently is composed of Messrs. Siegel, Talbott and Berns, has the authority, to the extent permitted by applicable law, to act for the Board in all matters arising between regular or special meetings of the Board of Directors.
 
The Audit Committee members are Messrs. Huff (chairman), Buckner and Hunt, each of whom is independent within the meaning of applicable Securities Exchange Act of 1934, as amended (the “Exchange Act”), rules and within the meaning of the NASDAQ listing standards. The Audit Committee oversees management’s conduct of Patterson-UTI’s accounting and financial reporting process, including review of the financial reports and other


4


Table of Contents

financial information provided by Patterson-UTI to the public and government and regulatory bodies, Patterson-UTI’s system of internal accounting, Patterson-UTI’s financial controls, and the annual independent audit of Patterson-UTI’s financial statements. The Audit Committee also oversees compliance with Patterson-UTI’s codes of conduct and ethics and with legal and regulatory requirements. The Board has determined that Messrs. Huff and Buckner are “audit committee financial experts” within the meaning of applicable SEC rules. The Audit Committee selects the independent registered public accounting firm to audit Patterson-UTI’s books and records and considers and acts upon accounting matters as they arise. The Board of Directors has adopted a written charter for the Audit Committee. The Audit Committee held seven meetings during the year ended December 31, 2008. Please see “Audit Committee Report” elsewhere in this proxy statement.
 
The Compensation Committee members are Messrs. Peak (chairman), Buckner and Huff, each of whom is independent as defined in the NASDAQ listing standards. Among other things, the Compensation Committee sets and administers the policies that govern the compensation of executive officers and directors of Patterson-UTI. The Board of Directors has adopted a written charter for the Compensation Committee. The Compensation Committee held four meetings during the year ended December 31, 2008. Please see “Compensation Discussion and Analysis” and “Compensation Committee Report” elsewhere in this proxy statement for further information about the Compensation Committee.
 
The Nominating and Corporate Governance Committee members are Messrs. Hunt (chairman), Huff and Peak, each of whom is independent as defined in the NASDAQ listing standards. The purpose of the Nominating and Corporate Governance Committee is to identify individuals qualified to become Board members, to recommend for selection by the Board director nominees for the next annual meeting of stockholders, to review Patterson-UTI’s Code of Business Conduct, to develop and continually make recommendations with respect to the best corporate governance principles and to oversee the evaluation of the Board and management. The Board of Directors has adopted a written charter for the Nominating and Corporate Governance Committee. The Nominating and Corporate Governance Committee held one meeting during the year ended December 31, 2008.
 
All of the director nominees are existing directors of Patterson-UTI standing for re-election to the Board of Directors.
 
On behalf of the Board, the Nominating and Governance Committee considers director nominees recommended by Patterson-UTI’s stockholders if the recommendations are made in accordance with all legal requirements, including applicable provisions of Patterson-UTI’s restated certificate of incorporation and bylaws. In accordance with Patterson-UTI’s bylaws, in addition to any other applicable requirements, nominations of persons for election to the Board may be made at a meeting of stockholders only by or at the direction of the Board or by a stockholder who is a stockholder of record on the date of the giving of the notice provided for below and on the record date for the determination of stockholders entitled to vote at such annual meeting and gives timely notice of such nomination in writing to the Secretary of Patterson-UTI. To be timely with respect to the 2010 annual meeting of stockholders, a stockholder’s notice must be delivered to or mailed and received at Patterson-UTI’s principal executive offices not earlier than February 3, 2010 and not later than March 5, 2010; provided, however, that in the event that the annual meeting is called for a date that is not within 30 days before or after June 3, 2010, notice by the stockholder must be received not later than the close of business on the tenth day following the day on which such notice of the date of the meeting was mailed or public disclosure of the annual meeting date was made, whichever occurs first.
 
A stockholder’s notice to the Secretary of Patterson-UTI shall set forth:
 
  •  as to each person whom the stockholder proposes to nominate for election or re-election as director, all information relating to such person that is required to be disclosed in solicitations of proxies for election of directors, or is otherwise required, in each case pursuant to Regulation 14A promulgated under the Exchange Act, or any successor regulation thereto,
 
  •  the name and record address of the stockholder proposing such nomination,
 
  •  the class and number of shares of Patterson-UTI that are beneficially owned by the stockholder,


5


Table of Contents

 
  •  a description of all arrangements or understandings between such stockholder and each proposed nominee and any other person or persons (including their names) pursuant to which the nomination or nominations are to be made by such stockholder, and
 
  •  a representation that such stockholder intends to appear in person or by proxy at the meeting to nominate the persons named in the notice.
 
Such notice must be accompanied by a written consent of each proposed nominee to being named as a nominee and to serve as a director if elected.
 
The Nominating and Corporate Governance Committee determines qualification criteria and procedures for the identification and recruitment of candidates for election to serve as directors of Patterson-UTI. The Nominating and Corporate Governance Committee relies on the knowledge and relationships of Patterson-UTI and its officers and directors, as well as third parties when it deems appropriate, to identify and evaluate nominees for director, including nominees recommended by stockholders.
 
Communication with the Board and its Independent Members
 
Persons may communicate with the Board, or directly with its Chairman, Mr. Siegel, by submitting such communication in writing in care of Chairman of the Board of Directors, Patterson-UTI Energy, Inc., 450 Gears Road, Suite 500, Houston, Texas 77067. Persons may communicate with the independent members of the Board by submitting such communication in writing to the Nominating and Corporate Governance Committee of the Board of Directors of Patterson-UTI Energy, Inc., 450 Gears Road, Suite 500, Houston, Texas 77067.
 
Although Patterson-UTI does not have a formal policy regarding attendance by members of the Board at its annual meetings of stockholders, directors are invited to attend annual meetings of Patterson-UTI stockholders. All directors attended the 2008 annual meeting of stockholders with one director attending in person and the remaining directors attending via telephone.

PROPOSAL NO. 2
 
RATIFICATION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
 
The Audit Committee appointed PricewaterhouseCoopers LLP as independent registered public accounting firm to audit the financial statements of Patterson-UTI for the fiscal year ending December 31, 2009, and directed that such engagement be submitted to the stockholders of Patterson-UTI for ratification. In recommending ratification by the stockholders of such engagement, the Board of Directors is acting upon the recommendation of the Audit Committee, which has satisfied itself as to PricewaterhouseCoopers LLP’s independence, professional competence and standing. Although ratification by stockholders of the engagement of PricewaterhouseCoopers LLP is not required by Delaware corporate law or Patterson-UTI’s restated certificate of incorporation or bylaws, the Audit Committee believes a decision of this nature should be made with the consideration of Patterson-UTI’s stockholders. If the stockholders fail to ratify the appointment, the Audit Committee will reconsider whether to retain PricewaterhouseCoopers LLP and may retain that firm or another without re-submitting the matter to our

Table of Contents

stockholders. Even if the appointment is ratified, the Audit Committee may, in its discretion, direct the appointment of a different independent registered public accounting firm at any time during the year if it determines that such change would be in the best interests of Patterson-UTI and its stockholders.
 
It is expected that one or more representatives of PricewaterhouseCoopers LLP will be present at the Meeting and will be given the opportunity to make a statement if they so desire. It also is expected that the representative(s) will be available to respond to appropriate questions from the stockholders.
 
The Board of Directors recommends a vote “FOR” the ratification of PricewaterhouseCoopers LLP as Patterson-UTI’s independent registered public accounting firm.  Ratification of the selection of PricewaterhouseCoopers LLP requires the affirmative vote of the holders of a majority of the shares of Common Stock present in person or by proxy, and entitled to vote at the Meeting. Unless you give contrary instructions in your proxy, your proxy will be voted “FOR” such ratification. Abstentions will be counted as shares entitled to vote on the proposal and will have the same effect as a vote “AGAINST” the proposal. A broker non-vote will be counted for purposes of establishing a quorum, but will not be treated as a share entitled to vote on the proposal.

COMPENSATION DISCUSSION AND ANALYSIS
 
Overview
 
Compensation Committee
 
The Compensation Committee (the “Committee”) sets and administers the policies that govern the compensation of executive officers and directors of Patterson-UTI. As part of its duties, the Committee determines the compensation of Patterson-UTI’s executive officers who are named in the Summary Compensation Table appearing elsewhere in this proxy statement (the “Named Executive Officers”) and grants all awards of restricted stock and stock options under Patterson-UTI’s long-term incentive plan.
 
The Committee currently consists of Messrs. Peak (chairman), Buckner and Huff, each of whom is an independent director as defined by the NASDAQ listing standards.
 
Compensation Objectives
 
The Committee’s objectives are to provide to the Named Executive Officers competitive compensation packages that will permit Patterson-UTI to attract and retain highly qualified individuals and to motivate and reward the Named Executive Officers for performance that benefits Patterson-UTI and its stockholders.
 
Role of Management and Compensation Consultant
 
All compensation decisions with respect to the Named Executive Officers of Patterson-UTI are made solely by the Committee. The Committee is permitted under its charter to delegate any of its powers to a subcommittee of the Committee. In performing its duties, the Committee considers input from senior management on individual performance and compensation matters.
 
In determining compensation for the Named Executive Officers for 2008, the Committee considered a variety of information, including (1) compensation for executive officers at similarly situated oilfield service companies, (2) historical and projected financial and operational results at Patterson-UTI, including margins achieved, rig utilization, net income and earnings before interest, taxes, depreciation and amortization (“EBITDA”) and return on equity and assets, (3) historical stock performance, (4) operational and strategic objectives of Patterson-UTI and (5) individual performance.
 
For 2008, the Committee engaged Towers Perrin, an independent compensation consultant, who reported directly to the Committee to evaluate and make recommendations to the Committee regarding Patterson-UTI’s executive compensation philosophy and practices. Towers Perrin reviewed the executive salaries, non-equity incentive compensation and long-term incentives for competitiveness with similarly situated oilfield service companies. Towers Perrin was provided a proposed representative peer group within the oilfield services industry based on various criteria and was provided information as to the responsibilities of the members of Patterson-UTI’s executive team in relationship to its peers. Towers Perrin also analyzed Patterson-UTI’s share utilization as compared to its peers for purposes of assessing dilution resulting from awards under Patterson-UTI’s incentive plans. Towers Perrin was asked to provide its advice as to Patterson-UTI’s incentive plans and the Committee’s proposed compensation of the Named Executive Officers and the reasonableness of that compensation.
 
For 2008, the Committee reviewed compensation data from the following peer group of companies: BJ Services Company, Cameron International Corporation, Diamond Offshore Drilling Inc., Ensco International Inc., FMC Technologies Inc., Helmerich & Payne Inc., Nabors Industries Ltd., National Oilwell Varco Inc., Noble Corp.,

Elements of Compensation
 
Patterson-UTI’s compensation program for its Named Executive Officers includes three primary elements: (1) base salary, (2) non-equity incentive compensation in the form of cash bonuses and (3) long-term incentive opportunities in the form of restricted stock and stock options. Below is a summary of each element of compensation. The general intent of the base salary for the Named Executive Officers was for that compensation to be around the 50th percentile of the peer group and for incentive and equity based compensation to be above the 75th percentile. These objectives were established based on Patterson-UTI’s historical top tier performance on returns on assets and equity and long-term share value creation as compared to peers.
 
Base Salary
 
Historically, the Committee has emphasized performance-based compensation in the form of non-equity and equity incentive compensation and has minimized salary adjustments. From 2004 through 2006 there were no increases to the base salaries of the Named Executive Officers. In February 2007, the base salary of Mr. Berns was increased from $215,000 to $265,000. In October 2007, upon being named President and Chief Executive officer of Patterson-UTI, Mr. Wall’s base salary was increased from $450,000 to $600,000. In February 2008, the base salary of Mr. Vollmer was increased from $275,000 to $350,000.
 
The base salaries of Named Executive Officers are reviewed and determined annually by the Committee based on (i) subjective evaluations of the officer’s functional position and specific performance, (ii) assessment of the relative importance of each position at Patterson-UTI, (iii) a comparison to salary ranges for executives of other companies in the oilfield service industry with market, financial and operational characteristics similar to those of Patterson-UTI, (iv) Patterson-UTI’s financial results and position and (v) Patterson-UTI’s performance compared to similarly situated companies.
 
Non-Equity Incentive Compensation
 
The Named Executive Officers have historically received non-equity incentive compensation in the form of annual cash bonuses designed to put a meaningful portion of total compensation at risk. In 2008, non-equity incentive compensation for Messrs. Siegel, Wall, Vollmer and Berns was tied to a bonus pool based upon Patterson-UTI’s EBITDA. The bonus pool was allocated among the four officers pursuant to a pre-determined sharing percentage that reflected a team-based philosophy as well as the organizational structure of the top management team. The bonus pool and allocation are subject to modification by the Committee at its discretion. EBITDA has been chosen as the performance measure for the annual cash bonus because Patterson-UTI believes it is an important measure of current year financial performance. Non-equity incentive compensation for Mr. Moll during 2008 was determined at the discretion of the Committee based on the operating performance of the Company and the individual performance of Mr. Moll.
 
In 2008, the bonus pool for Messrs. Siegel, Wall, Vollmer and Berns, subject to a minimum threshold of $400 million of EBITDA, was approximately 0.611 of one percent of Patterson-UTI’s EBITDA. The allocation of the bonus pool as a percentage of 2008 EBITDA was as follows: 0.222 of one percent to Mr. Siegel, 0.167 of one percent to Mr. Wall and 0.111 of one percent to each of Messrs. Vollmer and Berns. While, the Committee did not establish a specific threshold bonus amount for each such officer; the Grants of Plan-Based Awards table presents a threshold bonus amount for each such officer based on an assumed EBITDA at the minimum EBITDA threshold of $400 million and the allocation formula. The maximum amount that can be awarded to an individual under any cash-based performance award granted under the 2005 Plan during a 12-month period is $5,000,000. In order to reach this maximum amount, EBITDA of $2.25 billion in the case of Mr. Siegel, $3.00 billion in the case of Mr. Wall and $4.50 billion in the case of Messrs. Vollmer and Berns would have been needed. The Committee did not establish a target bonus amount. The target bonus amount presented in the Grants of Plan-Based Awards table is calculated for the respective officer based on Patterson-UTI’s actual EBITDA for the fiscal year ended December 31, 2008 and the allocation formula applied to the bonus pool for distribution.

Table of Contents

The aggregate bonus pool paid to Messrs. Siegel, Wall, Vollmer and Berns for 2008 was $5,013,720 based on Patterson-UTI’s 2008 EBITDA of $820,427,000. Based on the target allocation above, Mr. Siegel received $1,823,171; Mr. Wall received $1,367,378 and Messrs. Vollmer and Berns each received $911,586. Consistent with Patterson-UTI’s emphasis on performance-based compensation, non-equity incentive compensation for 2008 represented a significant portion of each Named Executive Officer’s total cash compensation from Patterson-UTI for the year.
 
The Committee has established a target bonus pool for 2009 for Messrs. Siegel, Wall, Vollmer and Berns, subject to a minimum EBITDA threshold of $200 million, of approximately 0.611 of one percent of Patterson-UTI’s EBITDA. The target allocation of the bonus pool as a percentage of 2009 EBITDA, is as follows: 0.222 of one percent to Mr. Siegel, 0.167 of one percent to Mr. Wall and 0.111 of one percent to each of Messrs. Vollmer and Berns.
 
Long-Term Incentive Compensation
 
Long-term incentive compensation for the Named Executive Officers consists of both awards of shares of restricted stock and options to purchase Common Stock, each of which vest over three or four years. Awards of such equity-based compensation reflect the Committee’s desire to provide the Named Executive Officers with additional incentives by increasing their proprietary interest in the success of Patterson-UTI. The Committee believes that there should be an emphasis on equity-based compensation in order to provide incentives and rewards that are closely aligned with stockholders. The Committee reviews equity-based compensation of the Named Executive Officers on an annual basis.
 
Patterson-UTI’s equity-based compensation has historically been given significant weight, along with non-equity incentive compensation, in the overall compensation package of the Named Executive Officers. The allocation of equity-based compensation among the Named Executive Officers is made by the Committee based on various factors, including the executive’s position and contribution to the overall goals and objectives of Patterson-UTI. The allocation and mix of equity-based compensation between restricted stock and stock options in 2008 followed this approach, with an emphasis on stock options over restricted stock for the four most highly compensated Named Executive Officers in order to ensure that the greatest awards would only be earned for increases in Patterson-UTI’s equity value.
 
The Committee’s practice has generally been to grant stock options and/or restricted stock to Named Executive Officers at a meeting following the conclusion of Patterson-UTI’s first quarter. Such meetings are typically held in conjunction with regular quarterly Board meetings that are held prior to Patterson-UTI’s public release of quarterly earnings information. Options are granted at an exercise price equal to the closing price of Patterson-UTI’s stock on the date of grant.
 
Retirement Plans
 
Patterson-UTI offers a 401(k) plan to its employees, including its Named Executive Officers. Participants may contribute a portion of their base salary to the 401(k) plan, subject to federal limits. Patterson-UTI makes matching contributions up to four percent of each participant’s eligible base salary. The Named Executive Officers of Patterson-UTI are eligible to participate in the 401(k) plan on the same basis as other employees. Patterson-UTI does not have any other retirement plan.
 
Perquisites and Personal Benefits
 
No Named Executive Officer received perquisites totaling more than $10,000. Accordingly, the perquisites do not meet the threshold which would require disclosure in the Summary Compensation Table below.
 
Share Ownership Guidelines
 
The Committee in 2004, with the approval of the Board, enacted share ownership guidelines applicable to all executive officers and directors of Patterson-UTI. Under these guidelines and subject to a four-year phase-in, each of Patterson-UTI’s Chairman, Chief Executive Officer and President was required to hold shares of Common Stock

Table of Contents

having a value equal to at least five times the officer’s base salary and each of Patterson-UTI’s other executive officers was required to hold shares of Common Stock having a value equal to at least three times the officer’s base salary. The Committee also enacted share ownership guidelines for directors. Under those guidelines, subject to a four-year phase-in, each director of Patterson-UTI was required to hold shares of Common Stock having a value equal to at least four times the annual base retainer provided to the director. Each of the Named Executive Officers and Directors was in compliance with these guidelines as of December 31, 2008.
 
In April 2009, in response to significant volatility in the market price of the Common Stock, the Nominating and Corporate Governance Committee modified the share ownership guidelines. The modified guidelines require the holding of a minimum number of shares of Common Stock rather than a specified dollar value of Common Stock. The modified guidelines require officers and directors to hold at all times, subject to a four year phase-in from the date first elected as an officer or director, at least the following number of shares of Common Stock:
 
                 
      Chairman     120,000 shares  
      President and Chief Executive Officer     90,000 shares  
      Senior Vice Presidents     60,000 shares  
      General Counsel     7,500 shares  
      Chief Accounting Officer     7,500 shares  
      Outside Directors     10,000 shares  
      Non-executive Inside Director     10,000 shares  
 
Each of the Named Executive Officers and Directors is in compliance with the modified guidelines as of the date of this proxy statement.
 
Change in Control and Severance Agreements
 
Patterson-UTI has entered into change in control agreements with its Named Executive Officers as further described elsewhere in this proxy statement. The Committee believes that the change in control agreements help Patterson-UTI to attract and retain the Named Executive Officers by reducing the personal uncertainty and anxiety that arises from the possibility of a future business combination. The Committee also believes the change in control agreements should prevent the Named Executive Officers from leaving employment out of concern for the security of their jobs or being unable to concentrate on their work.
 
Patterson-UTI has entered into written letter agreements with each of Messrs. Siegel, Berns and Vollmer pursuant to which Patterson-UTI has agreed to pay each such person within ten days of the termination of his employment with Patterson-UTI for any reason (including voluntary termination by him), an amount in cash equal to his annual base salary at the time of such termination. Patterson-UTI has entered into a severance agreement with Mr. Wall that generally has a three-year term and provides for a lump-sum cash payment of $750,000 to be payable to Mr. Wall within ten days of the date of a qualifying termination of his employment with Patterson-UTI. A qualifying termination for Mr. Wall is defined in the severance agreement generally as a termination by Patterson-UTI for any reason other than cause or, if certain conditions are met, a termination by Mr. Wall due to a reduction in his annual base salary below a defined threshold amount. Any payment made by Patterson-UTI pursuant to these letter agreements or the severance agreement will reduce dollar for dollar any payment owed to such person, if any, pursuant to the change in control agreements discussed above.
 
Section 162(m) Considerations
 
In considering compensation decisions for the executive management of Patterson-UTI, the Committee routinely considers the potential effect of Section 162(m) of the Internal Revenue Code. Section 162(m) imposes a limitation on corporate tax deductions for non-performance based compensation to certain officers that exceeds $1 million that can be taken by a publicly held corporation for compensation paid to certain of its executive officers. The Committee believes that tax deduction limitations should not compromise Patterson-UTI’s ability to establish and maintain appropriate executive compensation programs and reserves the right to award non-deductible compensation.

(1) For the fiscal year ended December 31, 2008, the bonus plan for Messrs. Wall, Vollmer, Siegel and Berns provided for a bonus pool based on EBITDA, subject to a minimum EBITDA of $400 million. The bonus pool was allocated among Messrs. Wall, Vollmer, Siegel and Berns based on a pre-determined sharing percentage. The threshold amount presented in this table is calculated for the respective officer based on an assumed EBITDA of $400 million and the allocation formula applied to the bonus pool for distribution due to the fact that the bonus plan provides for no payment if the minimum EBITDA of $400 million is not satisfied. The target amount is calculated based on Patterson-UTI’s actual EBITDA for the fiscal year ended December 31, 2008 and the allocation formula applied to the bonus pool for distribution. The cash bonuses awarded from the bonus pool were awarded under the 2005 Plan, which has been designed to meet the requirements of Section 162(m) of the Code. Although the bonus pool for Messrs. Wall, Vollmer, Siegel and Berns did not have an EBITDA cap, the maximum amount that could be awarded to an individual under any cash-based performance award granted under the 2005 Plan during a 12-month period is $5,000,000.
 
(2) Shares of restricted stock were awarded pursuant to the 2005 Plan. Ordinary dividends are paid on unvested shares of restricted stock. The rate at which these dividends are paid is the same rate at which ordinary dividends are paid on all other shares of common stock of Patterson-UTI. The right to receive these dividends has been included in the grant date fair value of stock awards presented in the table. The shares awarded to Messrs. Wall, Vollmer, Siegel and Berns vest over a three year period as follows: one-third on April 25, 2009, and the remaining two-thirds in equal monthly installments over the twenty-four months following April 25, 2009.

Directors who are also employees of Patterson-UTI do not receive compensation for serving as a director or as a member of a committee of the Board of Directors.

Each non-employee director that serves on the Audit Committee or the Compensation Committee receives additional annual cash compensation of $10,000 per committee on which he serves, with the chairman of each such committee receiving $15,000.
 
CHANGE IN CONTROL ARRANGEMENTS; EMPLOYMENT CONTRACTS;
INDEMNIFICATION AGREEMENTS; CERTAIN PAYMENTS
 
Patterson-UTI has entered into change in control agreements with Messrs. Siegel, Wall, Berns, Vollmer and Moll (each agreement, an “Agreement” and collectively, the “Agreements”; and each individual, an “Employee and collectively, the “Employees”). The Agreements were entered into to protect the Employees should a change in control occur, thereby encouraging the Employee to remain in the employ of Patterson-UTI and not be distracted from the performance of his duties to Patterson-UTI by the possibility of a change in control.
 
In the event of a change in control of Patterson-UTI in which an Employee’s employment is terminated by Patterson-UTI other than for cause or by the Employee for good reason, the terms of the Agreements would entitle the Employee to, among other things:
 
  •  a bonus payment equal to the highest bonus paid after the Agreement was entered into (such bonus payment prorated for the portion of the fiscal year preceding the termination date),
 
  •  a payment equal to 2.5 times (in the case of Messrs. Siegel and Wall), 2.0 times (in the case of Messrs. Berns and Vollmer) or 1.5 times (in the case of Mr. Moll) of the sum of (i) the highest annual salary in effect for


17


Table of Contents

  such Employee during the term of the Agreement and (ii) the average of the three annual bonuses earned by the Employee for the three fiscal years preceding the termination date (or a benchmark bonus in the case of Messrs. Wall and Moll), and
 
  •  continued coverage under Patterson-UTI’s welfare plans for up to three years (in the case of Messrs. Siegel and Wall) or two years (in the case of Messrs. Berns, Vollmer and Moll).
 
Each Agreement provides the Employee with a full gross-up payment for any excise taxes imposed on payments and benefits received under the Agreements or otherwise, including other taxes that may be imposed as a result of the gross-up payment.
 
A “change in control” is principally defined by the Agreement as:
 
  •  an acquisition by any individual, entity or group of beneficial ownership of 35% or more of either Patterson-UTI’s then outstanding Common Stock or the combined voting power of the then outstanding voting securities of Patterson-UTI entitled to vote in the election of directors,
 
  •  a change occurs in which the members of the Board of Directors as of the date of the Agreement cease to constitute at least a majority of Patterson-UTI’s Board of Directors unless that change occurs through a vote of at least a majority of the incumbent members of the Board of Directors, or
 
  •  a change in the beneficial ownership of Patterson-UTI following consummation of a reorganization, merger, consolidation, sale of Patterson-UTI or any subsidiary of Patterson-UTI or a disposition of all or substantially all of the assets of Patterson-UTI, in which the beneficial owners immediately prior to the transaction own 65% or less of outstanding Common Stock of the newly combined or merged entity.
 
The Agreements terminate on the first to occur of:
 
  •  the Employee’s death, disability or retirement,
 
  •  the termination of the Employee’s employment, or
 
  •  January 29, 2010 although, unless otherwise terminated, the Agreements automatically renew for successive twelve-month periods until Patterson-UTI notifies the Employee at least 90 days before the expiration of the initial term or the renewal period, as applicable, that the term will not be extended. Patterson-UTI has not provided any such notification to the Employees.
 
All unvested stock options and restricted stock awards held by Named Executive Officers vest upon a change of control as defined by the underlying award agreements. All restricted stock awards held by Named Executive Officers contain provisions that in the event of termination due to death or disability, the Named Executive Officer would vest in a portion of the unvested restricted stock.
 
Patterson-UTI has entered into written letter agreements with each of Messrs. Siegel, Berns and Vollmer pursuant to which Patterson-UTI has agreed to pay each such person within ten days of the termination of his employment with Patterson-UTI for any reason (including voluntary termination by him), an amount in cash equal to his annual base salary at the time of such termination. Patterson-UTI has entered into a severance agreement with Mr. Wall that generally has a three-year term and provides for a lump-sum cash payment of $750,000 to be payable to Mr. Wall within ten days of the date of a qualifying termination of his employment with Patterson-UTI. A qualifying termination for Mr. Wall is defined in the severance agreement generally as a termination by Patterson-UTI for any reason other than cause or, if certain conditions are met, a termination by Mr. Wall due to a reduction in his annual base salary below a defined threshold amount. Any payment made by Patterson-UTI pursuant to these letter agreements or the severance agreement will reduce dollar for dollar any payment owed to such person, if any, pursuant to the change in control agreements discussed above.

Bonus amounts earned in 2008 were not considered in this calculation as they were not determined until after December 31, 2008.
 
(3) Each of the Named Executive Officers’ option and stock award agreements provide that unvested options and awards will immediately vest upon a change in control. Amounts presented in the table represent the value of unvested option and stock awards using the market price of Patterson-UTI Common Stock at December 31, 2008. All unvested options held by the Named Executive Officers as of December 31, 2008 had exercise prices that were greater than the market price of Patterson-UTI Common Stock at December 31, 2008.
 
(4) Messrs. Wall, Vollmer and Moll participated in Patterson-UTI’s health and welfare plans as of December 31, 2008. The amounts presented represent Patterson-UTI’s portion of the premiums for three years in the case of Mr. Wall and two years in the case of Messrs. Vollmer and Moll based on the rates in effect at December 31, 2008.
 
All restricted stock awards held by Named Executive Officers provide that in the event of termination of employment due to death or disability, the Named Executive Officer would vest in a portion of the unvested restricted stock. With respect to Mr. Siegel, such a termination at December 31, 2008 would have resulted in the accelerated vesting of 60,462 shares with a fair value of $695,918. With respect to Messrs. Vollmer and Berns, such a termination at December 31, 2008 would have resulted in the accelerated vesting of 30,229 shares with a fair value of $347,936. With respect to Mr. Wall, such a termination would have resulted in the accelerated vesting of 40,583 shares with a fair value of $467,110. With respect to Mr. Moll, such a termination would have resulted in the accelerated vesting of 6,654 shares with a fair value of $76,588.
 
Patterson-UTI has entered into an indemnification agreement with each of its Named Executive Officers and directors containing provisions that may require Patterson-UTI, among other things, to indemnify such executive officers and directors against liabilities that may arise by reason of their status or service as executive officers or directors (subject to certain exceptions) and to advance expenses incurred as a result of any proceeding against them as to which they could be indemnified.
 
CERTAIN TRANSACTIONS
 
In connection with the acquisition by REMY Capital Partners III, L.P. (“REMY Capital”) of an ownership interest in UTI in March 1995, REMY Capital succeeded to a registration rights agreement with UTI. As the successor-in-interest to UTI, Patterson-UTI assumed this registration rights agreement pursuant to which REMY Capital has the right to require Patterson-UTI to use its reasonable efforts to register shares held by REMY Capital under the Securities Act of 1933, as amended. In the event that such rights are exercised in connection with a primary offering proposed by Patterson-UTI (or a secondary offering with which Patterson-UTI agrees to


19


Table of Contents

participate), REMY Capital would bear its pro rata share of the costs of the offering, other than legal, accounting and printing costs, all of which Patterson-UTI would bear. In the event that REMY Capital elects to exercise such rights other than in connection with an offering in which Patterson-UTI participates, REMY Capital would bear all costs of the offering. These rights continue so long as REMY Capital continues to own the Common Stock that it acquired in March 1995. As of the date of this proxy statement, REMY Capital continues to hold 1,000,000 shares of Common Stock.
 
Mr. Siegel, Chairman of the Board of Patterson-UTI, is President and sole stockholder of REMY Investors, which is the general partner of REMY Capital. Mr. Berns, a director and Senior Vice President of Patterson-UTI, is an executive of REMY Investors.
 
In connection with Mr. Vollmer’s appointment as Chief Financial Officer, Patterson-UTI delivered a letter to Mr. Vollmer dated February 6, 2006 (the “Letter Agreement”). Pursuant to the Letter Agreement, Patterson-UTI agreed, to the extent permitted by law and provided that the applicable accounting restatement pending at that time did not result from Patterson-UTI’s material non-compliance with financial reporting requirements under the federal securities laws as a result of knowing misconduct by Mr. Vollmer:
 
  •  Patterson-UTI is not entitled to and will not make any claim against Mr. Vollmer for reimbursement of any bonus or other incentive or equity based compensation received by him or any profits realized by him from the sale of securities of Patterson- UTI, under Section 304 of the Sarbanes-Oxley Act of 2002 (“Section 304”) on account of the restatement of any financial statements of Patterson-UTI covering any accounting period ending on or prior to September 30, 2005;
 
  •  Patterson-UTI will not make any claim against Mr. Vollmer for any profits realized from the sale of securities of Patterson-UTI that were owned by him prior to his becoming Chief Financial Officer or were acquired by him on account of the exercise of options or the settling of restricted stock units that were held by him immediately prior to his becoming Chief Financial Officer, under Section 304 on account of the restatement of any financial statements of Patterson-UTI covering any period during which he was Chief Financial Officer; and
 
  •  Patterson-UTI will indemnify Mr. Vollmer against all losses in connection with his defense of any claim against him under Section 304 in contravention of the two immediately preceding bullets, to the extent he is obligated to reimburse Patterson-UTI for any bonus or other incentive or equity compensation received by him or any profits realized by him for the sale of Patterson-UTI securities.
 
Notwithstanding court decisions that Patterson-UTI’s right to make any such claims appears doubtful, Patterson-UTI has entered into this agreement because of the breadth of language of Section 304 and the uncertainty as to how the statute may be interpreted by the courts in the future and the importance at the time of Mr. Vollmer’s continued service as Chief Financial Officer.
 
Patterson-UTI has a written policy with respect to related person transactions. In accordance with this policy, related person transactions are reviewed by the Lead Director or the chair of the Audit Committee, each of whom has full delegated authority to approve, disapprove, ratify, amend, terminate or rescind any such transaction, or direct that such transaction be submitted to the Audit Committee or the full Board of Directors for consideration. In approving or disapproving related person transactions, the relevant facts and circumstances of the related person transaction are considered, including whether such transaction is in, or not inconsistent with, the best interest of Patterson-UTI and whether, in appropriate cases, such transaction is on commercial terms at least as favorable to Patterson-UTI as would otherwise be available to or from an unrelated third party or to Patterson-UTI’s employees generally. Related person transactions generally include transactions in an amount that exceeds $50,000 between Patterson-UTI or any of its subsidiaries and an executive officer, a director (or nominee to become director), an immediate family member of any of the foregoing or any entity in which any of the foregoing has a 10% or greater beneficial ownership interest or in which they are an executive officer, general partner, principal or engaged in a similar position. Certain related person transactions have been pre-approved under the terms of the policy, including, subject to certain exceptions and limitations, the sale to or purchase from Patterson-UTI of goods and services by entities related to directors in the ordinary course of business that are immaterial to Patterson-UTI and with respect to which the director has no direct economic interest or decision making authority.

Taking the foregoing into consideration, the undersigned Audit Committee members recommended to the Board of Directors that the Board approve the inclusion of the Patterson-UTI’s audited financial statements in the Annual Report on Form 10-K for the fiscal year ended December 31, 2008.
