SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION. -------------------------------------------------- Working Capital ITEM 4. PURPOSE OF TRANSACTION. ----------------------- (a) Item 4(a) of the Statement is hereby amended and restated in full as follows: The Reporting Person presently beneficially owns an aggregate of 6,662,505 shares of Common Stock. The Reporting Person acquired 800,000 shares of Common Stock (the "Initial Shares") prior to June 30, 1997, the date of the First Closing under the Securities Purchase Agreement described below. The Reporting Person subsequently acquired 4,923,630 shares of Common Stock and Warrants covering an aggregate of 1,450,000 shares of Common Stock pursuant to the terms of a Securities Purchase Agreement, dated as of May 13, 1997 (the "Securities Purchase Agreement"), between the Reporting Person and the Company. At the same time as the parties entered into the Securities Purchase Agreement, the parties and/or their affiliates entered into (i) the Warrant Agreement, dated as of May 13, 1997 (the "Warrant Agreement") between the Reporting Person and the Company and (ii) the Registration Rights Agreement, dated as of May 13, 1997 (the "Registration Rights Agreement") between the Reporting Person and the Company. The Initial Shares were acquired by Procter & Gamble Pharmaceuticals, Inc., a wholly owned subsidiary of the Reporting Person pursuant to (i) a Stock Purchase Agreement, dated as of December 11, 1996 (the "Initial Purchase Agreement"), between Procter & Gamble Pharmaceuticals, Inc. and the Company, and (ii) the Registration Rights Agreement, dated as of December 11, 1996 (the "Initial Registration Rights Agreement"), between Procter & Gamble Pharmaceuticals, Inc. and the Company. Of the total shares of Common Stock and Warrants acquired on June 30, 1997 pursuant to the Securities Purchase Agreement, 4,350,000 shares of Common Stock and all of the Warrants were acquired at the initial closing under the Securities Purchase Agreement on June 30, 1997 (the "First Closing"). At the First Closing, the Reporting Person acquired such shares of Common Stock and Warrants for an aggregate cash purchase price of $42,934,500. In addition, pursuant to its commitment in the Securities Purchase Agreement to acquire additional shares of Common Stock at the election of the Company prior to June 30, 2002, the Company sent notice on May 31, 2000 to the Reporting Person requiring such Reporting Person to acquire an additional 573,630 shares of Common Stock of the Company at a purchase price of $29.75 per share in cash (for a total consideration of $17,065,492.50). This per share price was the same price at which the Company issued shares of Common Stock in its public offering consummated on April 4, 2000. This transaction closed on August 3, 2000. Pursuant to a memorandum of understanding between the Reporting Person and the Company entered into on August 3, 2000 (the "MOU"), the parties agreed to restructure the scope and terms of the collaboration agreement between the parties for a five year period commencing January 1, 2001. As part of the MOU, the Warrants were amended to permit the cashless exercise thereof - that is, the Reporting Person, in lieu of exercising the Warrants for cash, would instead be permitted to tender shares of Common Stock for the exercise price of the Warrants and surrender the Warrants with no cash payment and receive in exchange shares of Common Stock equal in current market value to the excess of the current market value of the shares of Common Stock covered by the Warrants over the exercise price of the Warrants. The current market value is the average trading price of the Company's Common Stock over the 30 trading days commencing 33 trading days preceding the date of exercise. On August 3, 2000, following the amendment to the Warrant Agreement as described above, the Reporting Person exercised all of the Warrants pursuant to the cashless exercise provisions and received in exchange therefor 938,875 shares of Common Stock, based on the current market value of $28.00 per share. Also, as part of the MOU, the Reporting Person agreed not to sell any shares of Common Stock of the Company until the earliest of (i) December 31, 2000; (ii) the date on which the Company enters into an agreement with a third party or parties in which the Company receives at least $50 million in committed capital to the Company; and (iii) a public offering of Common Stock of the Company. After the expiration of this restriction, the Reporting Person may sell some or all of its share of Common Stock at any time. Any decision by the Reporting Person as to the sale of such shares after the expiration of this restriction will depend on prevailing market conditions, the Reporting Person's view of the prospects of the Company and other factors. The purpose of the acquisition by the Reporting Person of all of the shares of Common Stock beneficially owned by it is for general investment purposes and to realize the potential appreciation in the value of the Common Stock based on the Reporting Person's view of the prospects of the Company at the time the Reporting Person entered into the Securities Purchase Agreement. In making its investment, the Reporting Person considered the Company's plans and prospects, including the business opportunities that might arise from the commercial research and development collaboration arrangements between the parties contemplated by the collaboration agreement. The Reporting Person does not hold the shares of Common Stock it beneficially owns with the purpose or effect of changing or influencing control of the Company. The Reporting Person has no representative on the Board of Directors of the Company nor any right to manage the business or affairs of the Company. (b) None (c) None (d) None (e) None (f) None (g) None ITEM 5. INTERESTS IN SECURITIES OF THE COMPANY. (a) As of August 3, 2000 the Reporting Person beneficially owns 6,662,505 shares of Common Stock, representing 19.7% of the total shares of Common Stock. (b) The Reporting Person has sole voting power over all shares of Common Stock so beneficially owned by it and does not share voting power over any such shares. The Reporting Person has sole dispositive power over all shares of Common Stock so beneficially owned by it and does not share dispositive power over any such shares. (c) None (d) Not applicable. (e) Not applicable. ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE COMPANY. -------------------------------------------------------- Item 6 to Schedule 13D is hereby amended as follows: The terms of the Warrants were amended to permit the cashless exercise thereof as described in Item 4 above.
