The principal executive offices of the Company are located at 16020 Industrial Drive, Gaithersburg, MD 20877. Item 2. Identity and Background. In accordance with Securities and Exchange Commission Release No. 34-39538 (January 12, 1998), this Statement is being filed by Credit Suisse First Boston (the "Bank"), a Swiss bank, on behalf of itself and its subsidiaries, to the extent that they constitute the Credit Suisse First Boston business unit (the "CSFB business unit") excluding Asset Management (as defined below) (the "Reporting Person"). The CSFB business unit is also comprised of an asset management business principally conducted under the brand name Credit Suisse Asset Management ("Asset Management"). The Reporting Person provides financial advisory and capital raising services, sales and trading for users and suppliers of capital around the world and invests in and manages private equity and venture capital funds. Asset Management provides asset management and investment advisory services to institutional, mutual fund and private investors worldwide. The address of the Bank's principal business and office is Uetlibergstrasse 231, P.O. Box 900, CH 8070 Zurich, Switzerland. The address of the Reporting Person's principal business and office in the United States is Eleven Madison Avenue, New York, New York 10010. The Bank owns directly a majority of the voting stock, and all of the non-voting stock, of Credit Suisse First Boston, Inc. ("CSFBI"), a Delaware corporation. The address of CSFBI's principal business and office is Eleven Madison Avenue, New York, New York 10010. The ultimate parent company of the Bank and CSFBI, and the direct owner of the remainder of the voting stock of CSFBI, is Credit Suisse Group ("CSG"), a corporation formed under the laws of Switzerland. CSFBI owns all of the voting stock of Credit Suisse First Boston (USA), Inc. ("CSFB-USA"), a Delaware corporation and holding company. CSFB-USA is the sole member of Credit Suisse First Boston LLC ("CSFB LLC"), a Delaware limited liability company and a registered broker-dealer that effects trades in many companies, including the Company. CSFB LLC is the successor company of Credit Suisse First Boston Corporation ("CSFBC"), and all references hereinafter to CSFBC shall be deemed to refer to CSFB LLC. The address of the principal business and office of each of CSFB-USA and CSFB LLC is Eleven Madison Avenue, New York, New York 10010. CSG is a global financial services company with two distinct business units. In addition to the CSFB business unit, CSG is comprised of the Credit Suisse Financial Services business unit (the "Credit Suisse Financial Services business unit"), which offers investment products, private banking and financial advisory services, including insurance and pension solutions, for private and corporate clients in Europe and other markets around the world. CSG's business address is Paradeplatz 8, P.O. Box 1, CH 8070 Zurich, Switzerland. CSG, for purposes of the federal securities laws, may be deemed ultimately to control the Bank and the Reporting Person. CSG, its executive officers and directors, and its direct and indirect subsidiaries (including Asset Management and the Credit Suisse Financial Services business unit) may beneficially own the Shares of the Company to which this Statement relates, and such Shares are not reported in this Statement. CSG disclaims beneficial ownership of Shares beneficially owned by its direct and indirect subsidiaries, including the Reporting Person. Each of Asset Management and the Credit Suisse Financial Services business unit disclaims beneficial ownership of Shares beneficially owned by the Reporting Person. The Reporting Person disclaims beneficial ownership of Shares beneficially owned by CSG, Asset Management and the Credit Suisse Financial Services business unit. The name, business address, citizenship, present principal occupation or employment, and the name and business address of any corporation or organization in which each such employment is conducted, of each executive officer or director of the Reporting Person, CSFBI, CSFB-USA, and CSFB LLC are set forth on Schedules A-1 through A-4 attached hereto, each of which is incorporated by reference herein. Except as otherwise provided herein, during the past five years none of the Reporting Person, CSFBI, CSFB-USA, CSFB LLC, nor, to the best knowledge of the Reporting Person, any of the other persons listed on Schedules A-1 through A-4 attached hereto, has been (i) convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (ii) a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to United States federal or state securities laws or finding any violation with respect to such laws. On January 22, 2002, CSFBC, without admitting or denying any alleged violation, entered into coordinated settlements with NASD Regulation, Inc. ("NASDR") and the Securities and Exchange Commission ("SEC") resolving all outstanding investigations of CSFBC into the allocation of shares in initial public offerings ("IPOs"). CSFB-USA was then the sole stockholder of CSFBC. CSFBC consented to these settlements without admitting or denying any of the allegations made in the SEC's Complaint or the Letter of Acceptance, Waiver and Consent ("AWC") filed with the NASDR. The SEC and NASDR alleged that, between April 1999 and June 2000, certain CSFBC employees allocated many shares in IPOs to over 100 customers with whom they had improper profit-sharing arrangements. The NASDR and SEC alleged that certain employees allocated "hot" IPO shares to certain customers who paid the Firm a portion of the profits (between 33 and 65 percent) that they made when they sold their IPO stock, by paying inflated brokerage commissions on transactions unrelated to the IPO shares. Under the terms of the coordinated settlement: o CSFBC paid a total of $100 million. This amount included $30 million in fines and civil penalties divided evenly between the SEC and NASDR, and a total of $70 million in disgorgement, $35 million of which was paid to the U.S. Treasury and $35 million of which was paid to the NASDR, representing the monies obtained as a result of the conduct described by the SEC and NASDR. The SEC determined in this case that it was appropriate and in the public interest to pay funds to the U.S. Treasury rather than to any third parties. o CSFBC has adopted and implemented revised policies and procedures for allocating IPOs in its broker-dealer operations. The SEC and NASD have reviewed these policies and procedures. These included the establishment of an IPO Allocation Review Committee, a process for the pre-qualification of accounts before they are eligible to receive IPO allocations and enhanced supervisory procedures, which includes the review of commissions paid by certain accounts receiving allocations around the time of the IPO. CSFBC also agreed to retain an independent consultant to review the implementation of these policies and procedures one year from the date of the settlement. In the NASDR settlement, CSFBC, without admitting or denying any findings, consented to a censure and findings that it violated NASD Rules 2110, 2330, 2710, 3010 and 3110. These Rules (a) require broker-dealers to adhere to just and equitable principles of trade, (b) prohibit broker-dealers from sharing in the profits of client accounts except as specifically provided, (c) require a managing underwriter to file certain information that may have a bearing on the NASDR's review of underwriting arrangements, (d) require members to establish, maintain and enforce a reasonable supervisory system, and (e) require broker-dealers to maintain certain books and records. The NASDR AWC also found violations of Section 17(a) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and SEC Rule 17a-3, thereunder, which are incorporated by NASD Rule 3110 and similarly impose certain record keeping requirements on CSFBC as a broker-dealer. In the SEC settlement, CSFBC, without admitting or denying the allegations of the Complaint, consented to entry by the District Court for the District of Columbia of a final judgment that: (1) permanently enjoined CSFBC, directly or indirectly, from violations of NASD Conduct Rules 2110 and 2330 and Section 17(a)(1) of the Exchange Act and SEC Rule 17a-3; and (2) ordered CSFBC to comply with certain undertakings. Neither the SEC nor NASDR made any allegations or findings of fraudulent conduct by CSFBC. Further, neither the SEC nor NASDR alleged that any IPO prospectus was rendered false or misleading by CSFBC's conduct or that this conduct affected either the offering price of an IPO or the price at which any IPO stock traded in the aftermarket. On October 31, 2003, the U.S. District Court for the Southern District of New York (the "SDNY") approved the global settlement among a number of Wall Street firms, including CSFB LLC, and a coalition of state and federal regulators and self-regulatory organizations (the "Global Settlement"). CSFB LLC, without admitting or denying any alleged violation, consented to the Global Settlement and thereby resolved a Securities and Exchange Commission's ("SEC") complaint filed on April 28, 2003, in the SDNY. In this complaint, the SEC alleged that, from July 1998 to December 2001, CSFB LLC engaged in acts and practices that created or maintained inappropriate influence over research analysts, thereby imposing conflicts of interest on research analysts that CSFB LLC failed to manage in an adequate or appropriate manner. The SEC's complaint also alleged that CSFB LLC engaged in inappropriate "spinning" of "hot" IPO allocations in violation of New York Stock Exchange ("NYSE") and NASD Inc. ("NASD") rules requiring adherence to high business standards and just and equitable principles of trade, and that CSFB LLC's books and records relating to certain transactions violated the broker-dealer record-keeping provisions of Section 17(a) of the Securities Exchange Act of 1934, NYSE Rules 401, 440 and 476(a)(6) and NASD Rules 2110 and 3110. Under the terms of the Global Settlement: o CSFB LLC agreed to pay the following amounts: $75 million as a penalty, $75 million as disgorgement of commissions and other monies for restitution for investors, and $50 million to be used to fund independent research. This $50 million to fund independent research is payable over a five year period. o CSFB LLC is required, among other things, to: (i) separate its research and investment banking departments and make independent research available to investors, (ii) prohibit its analysts from receiving compensation for investment banking activities and prohibit analysts' involvement in investment banking "pitches" and "roadshows," (iii) contract, for a five-year period, with no fewer than three independent research firms that will make available independent research to CSFB's customers, and (iv) make its analysts' historical price targets (among other things) publicly available. o CSFB LLC is permanently restrained and enjoined from violating Sections 15(c) and 17(a) of the Exchange Act, Exchange Act Rules 15c1-2 and 17a-3, NASD Rules 2110, 2210, 3010, and 3110, and NYSE Rules 342, 401, 440, 472, and 476. Other Wall Street firms were subject to similar requirements. Item 3. Source and Amount of Funds. On February 13, 2004, IGEN International, Inc. ("IGEN") announced that it had been acquired by Roche Holding Ltd. in a transaction (the "Merger"), in which IGEN stockholders received US$47.25 in cash, without interest, and one Share of the Company for each share of IGEN common stock they owned immediately prior to the closing. On February 13, immediately prior to closing, CSFB LLC held 1,128,441 shares of IGEN common stock. The aggregate consideration (exclusive of commissions) paid by CSFB LLC for these shares of IGEN was US$64,911,068.75. CSFB LLC received 1,128,441 Shares as a result of the Merger. Following the Merger, CSFB has acquired an additional 262,200 Shares. The aggregate consideration (exclusive of commissions) paid by CSFB LLC for these additional Shares was US$4,129,900.00. The funds used by CSFB LLC to make these acquisitions, and the acquisitions described in Schedule B attached hereto, came from working capital. Item 4. Purpose of the Transaction. CSFB LLC acquired 2,795 Shares for customer facilitation purposes, 10,081 Shares as part of index arbitrage trading strategies, 1,105,074 Shares as part of risk arbitrage trading strategies, 7,991 Shares as part of statistical arbitrage trading strategies, 5,000 Shares as part of its activities related to discretionary trading accounts and 259,700 Shares as part of its activities related to proprietary trading accounts. CSFB LLC intends to optimize the value of its investments and, therefore, will review from time to time the Company's business affairs and financial position. Based on such evaluation and review, as well as general economic and industry conditions existing at the time, CSFB LLC may consider from time to time various alternative courses of action. Such actions may include the acquisition of additional Shares or other securities through open market purchases, privately negotiated transactions, a tender offer, an exchange offer or otherwise. Alternatively, such actions may involve the sale of all or a portion of the Shares or other securities in the open market, in privately negotiated transactions, through a public offering or otherwise. Except as set forth herein, each of the Reporting Person and CSFB LLC has no present plans or proposals that relate to or that would result in any of the actions specified in clauses (a) through (j) of Item 4 of Schedule 13D. Item 5. Interest in Securities of the Issuer. (a) As of February 20, 2004, the Reporting Person may be deemed to beneficially own an aggregate of 1,390,641 Shares, consisting of 1,390,641 Shares held directly by CSFB LLC. Accordingly, the Reporting Person may be deemed to beneficially own 5.2% of the outstanding Shares. To the best knowledge of the Reporting Person, and except as described herein, neither the Reporting Person, CSFBI, CSFB-USA, CSFB LLC, nor, to the best knowledge of the Reporting Person, any other persons listed on Schedules A-1 through A-4 attached hereto, beneficially owns any additional Shares. (b) With respect to any rights or powers to vote, or to direct the vote of, or to dispose of, or direct the disposition of, the Shares referenced in paragraph 5(a), there is shared power to vote, or to direct the vote of, and to dispose of, or to direct the disposition of, such Shares among the Reporting Person, CSFBI, CSFB-USA and CSFB LLC. (c) Schedule B, which is incorporated herein by reference, sets forth the transactions in the Shares effected by the Reporting Person and its subsidiaries during the period beginning December 22, 2003 and ending February 20, 2004, inclusive. (d) No other person is known by the Reporting Person to have the right to receive or power to direct the receipt of dividends from, or the proceeds from the sale of, the Shares beneficially owned by the Reporting Person, CSFBI, CSFB-USA or CSFB LLC. (e) Not applicable. Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer. Not applicable. Item 7. Material to be filed as Exhibits.
