ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS On June 12, 2003, OSI Pharmaceuticals, Inc. completed its acquisition of Cell Pathways, Inc. in a stock-for-stock merger valued at approximately $31 million based on the five-day average closing prices of OSI's common stock at the time of the announcement of the merger in February 2003. The acquisition was structured as a merger of a wholly-owned subsidiary of OSI with and into Cell Pathways pursuant to an Agreement and Plan of Merger among OSI, Cell Pathways and CP Merger Corporation, dated as February 7, 2003. As a result of the merger, OSI acquired (1) a technology platform designed to selectively induce apoptosis, or programmed cell death, in pre-cancerous and cancerous cells; (2) two drug candidates in clinical development: Aptosyn(R) (exisulind) and CP461; and (3) a marketed oncology product, Gelclair(TM). In addition, OSI also acquired certain other assets, including the lease to a facility, property and equipment, and assumed certain liabilities. As consideration for the merger, each share of Cell Pathways common stock was exchanged for (i) 0.0567 of a share of OSI common stock and (ii) a contingent value right to receive 0.04 of a share of OSI common stock in the event a new drug application is accepted for filing with the U.S. Food and Drug Administration by June 12, 2008 for either of the two newly acquired clinical candidates, Aptosyn(R) (exisulind) or CP461. Based on the exchange ratio of 0.0567, approximately 2.2 million shares of OSI common stock were issued to Cell Pathways' stockholders in connection with the merger. Any outstanding options that were not exercised prior to the effective date of the merger were, in accordance with their terms, terminated. OSI has assumed each outstanding and unexercised warrant to purchase shares of Cell Pathways common stock pursuant to the same terms and conditions applicable to the respective Cell Pathways warrant except that the exercise price of the warrant and the number of shares of OSI common stock for which the warrant is exercisable were adjusted pursuant to a certificate of adjustment based on the exchange ratio described above. The number of shares of OSI common stock delivered as the merger consideration was determined through arms-length negotiation between the parties. There was no material relationship between Cell Pathways or its stockholders and OSI or any of its affiliates, directors or officers, or any associate of an OSI director or officer. The Agreement and Plan of Merger was filed by OSI as Exhibit 2.1 to the Form 8-K filed on February 11, 2003 and is incorporated herein by reference. Further details regarding the transaction are contained in OSI's press release dated June 12, 2003, attached to this Current Report on Form 8-K as Exhibit 99.1 and incorporated herein by reference.
