ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS. On July 18, 2001, Vertex Pharmaceuticals Incorporated completed the acquisition of Aurora Biosciences Corporation. The acquisition was structured as a merger of Ahab Acquisition Sub, Inc., a wholly owned subsidiary of Vertex, with and into Aurora. The merger was a tax-free stock-for-stock exchange and will be accounted for as a "pooling of interests" business combination. Pursuant to the terms of an Agreement and Plan of Merger, dated as of April 29, 2001, among Vertex, Ahab Acquisition Sub, Inc. and Aurora, each outstanding share of Aurora common stock was converted into 0.62 of a share of Vertex common stock, plus cash in lieu of fractional shares. As a result, Vertex is issuing approximately 14,138,022 shares of its common stock to former stockholders of Aurora in connection with the merger. In addition, upon completion of the merger, Vertex assumed outstanding options to purchase shares of Aurora common stock. Each option assumed by Vertex was converted into an option to purchase a number of shares of Vertex common stock equal to the number of shares of Aurora common stock issuable upon exercise of the option, multiplied by 0.62, rounded down to the nearest whole share. The per share exercise price of each assumed option was adjusted by dividing the exercise price of the Aurora option by 0.62, rounded up to the nearest whole cent. As a result, the assumed options are exercisable in the aggregate for approximately 2,757,632 shares of Vertex common stock at a weighted average exercise price of approximately $14.10. Aurora develops and commercializes technologies, products and services to accelerate the discovery of new medicines by the pharmaceutical and biopharmaceutical industries. Aurora will continue its operations as a wholly-owned subsidiary of Vertex and will retain the name Aurora Biosciences Corporation. Dr. Stuart J.M. Collinson, the former Chairman of the Board, President and Chief Executive Officer of Aurora, has been elected as a director of Vertex. ITEM 7. FINANCIAL STATEMENTS AND EXHIBITS.
