ITEM 1.01. ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

Merger Agreement

On August 21, 2005, Eyetech Pharmaceuticals, Inc., a Delaware corporation (the “Company”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with OSI Pharmaceuticals, Inc., a Delaware corporation (the “Buyer”), and Merger EP Corporation, a Delaware corporation and wholly owned subsidiary of the Buyer (“Merger Sub”). Under the Merger Agreement, Merger Sub will be merged with and into the Company (the “Merger”), with the Company continuing after the Merger as the surviving corporation and a wholly owned subsidiary of the Buyer. At the effective time of the Merger, each outstanding share of the Company’s common stock, par value $0.01 per share, will be converted into the right to receive (i) $15.00 per share in cash and (ii) 0.12275 fully paid and non-assessable shares of common stock of the Buyer, $0.01 par value per share. All outstanding options under the Company’s 2001 Stock Plan will be assumed by the Buyer. All outstanding options under the Company’s 2003 Stock Incentive Plan and options that were granted outside of the Company’s stock plans that are not exercised prior to the effective time of the Merger will be cancelled.

The Merger Agreement has been approved by the Company’s Board of Directors. The transactions contemplated by the Merger Agreement are subject to adoption of the Merger Agreement by the holders of a majority of the outstanding shares of the Company’s common stock. The transactions contemplated by the Merger Agreement are also subject to the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and other customary closing conditions. The Merger is expected to close by the end of 2005.

The foregoing description of the Merger Agreement is not complete and is qualified in its entirety by reference to the Merger Agreement, which is filed as Exhibit 2.1 hereto and is incorporated herein by reference.

In connection with the execution of the Merger Agreement, certain stockholders of the Company executed agreements with the Buyer to vote their shares of the Company’s common stock in favor of adoption of the Merger Agreement and against a defined category of competing proposals to acquire the Company (the “Voting Agreements”). The shares subject to the Voting Agreements represent in the aggregate approximately 8.2% of the outstanding shares of the Company’s common stock. If the Merger Agreement is terminated for any reason, the Voting Agreements will also terminate.

ADDITIONAL INFORMATION ABOUT THE MERGER AND WHERE TO FIND IT

The Buyer intends to file a registration statement on Form S-4 with the Securities and Exchange Commission containing a proxy statement/prospectus in connection with the proposed Merger. The proxy statement/prospectus will be mailed to the stockholders of the Company to consider and vote upon the proposed Merger. Investors and stockholders are urged to carefully read the proxy statement/prospectus and other relevant materials filed with the SEC when they become available because they will contain important information about the Buyer, the Company, the Merger, and other related matters. Investors and stockholders may obtain free copies of these documents (when they are available) and other documents filed with the SEC at the SEC’s web site at www.sec.gov. These documents can also be obtained for free from the Buyer by directing a request to the Buyer’s Investor Relations at 631-962-2000 and for free from the Company by directing a request to the Company’s Investor Relations at 212-824-3100.

PARTICIPANTS IN THE MERGER

The Buyer, the Company and their respective executive officers, directors and other members of management or employees may be deemed to be participants in the solicitation of proxies from the Company’s stockholders with respect to the transactions contemplated by the Merger Agreement. Information regarding the Buyer’s executive officers and directors is available in the Buyer’s Annual Report on Form 10-K for the year ended September 30, 2004 and its proxy statement dated February 2, 2005 for its 2005 Annual Meeting of Stockholders, which are filed with the SEC. Information regarding the Company’s executive officers and directors is available in the Company’s Annual Report on Form 10-K for the year ended December 31, 2004, its proxy statement dated April 11, 2005 for its 2005 Annual Meeting of Stockholders and its Current Report on Form 8-K dated June 15, 2005,

which are filed with the SEC. You can obtain free copies of these documents from the Buyer and the Company using the contact information above. Additional information regarding interests of such participants will be included in the registration statement containing the proxy statement/prospectus that will be filed with the SEC and available free of charge as indicated above.

In addition, in connection with the execution of the Merger Agreement, Dr. David Guyer, the Company’s Chief Executive Officer, Paul G. Chaney, the Company’s Chief Operating Officer, and Dr. Anthony P. Adamis, the Company’s Chief Scientific Officer, have entered into letter agreements with the Buyer setting forth the terms under which these individuals will continue their employment with the Buyer following the Merger. Furthermore, in connection with the execution of the Merger Agreement, the Company’s Board of Directors authorized the payment of transaction completion bonuses in the aggregate amount of $350,000. The recipients of these bonuses, and the amounts they may receive, will be determined by the Company’s Board of Directors based on the recommendation of its Compensation Committee. Such recipients may include executive officers of the Company. Additional information regarding these arrangements and the interests of such participants will be included in the registration statement containing the proxy statement/prospectus that will be filed with the SEC and available free of charge as indicated above.
