Since July 6, 1998, Partners, in its capacity as general partner of BVF, has purchased on behalf of such limited partnership an aggregate number of 158,150 shares of the Stock for an aggregate consideration of $2,732,959.48.00, utilizing funds provided by BVF from its working capital pursuant to the terms of its limited partnership agreement with Partners and has sold an aggregate number of 98,000 shares of the Stock for an aggregate consideration of $1,519,949.33. In addition, Partners, in its capacity as investment manager with respect to certain managed accounts, has purchased on behalf of such managed accounts an aggregate number of 238,750 shares of the Stock for an aggregate consideration of $6,705,048.10, utilizing funds under management by Partners pursuant to investment management agreements between Partners and such managed accounts and has sold an aggregate number of 117,000 shares of the Stock for an aggregate consideration of $3,329,608.97. ITEM 4. PURPOSE OF TRANSACTION. The external environment for small, quality biotechnology companies is undergoing a period of rapid and profound change. The convergence of a depressed equity market, the possible slowing pace of a corporate partnering activity, and escalating cash burn rates could produce an industry shake-out in which financially conservative companies prosper and financially weak companies falter. This changing environment may call for managements and Boards to husband capital by significantly reducing cash burn rates and to otherwise alter preconceived business plans. If managed pro-actively and intelligently, this period could yield attractive returns for shareholders. However, the consequences of complacency and the potential for irreparable missteps are great. BVF may seek to work with company managements, Boards and shareholders to maximize shareholder value and, specifically, to protect the substantial value of funded, partnered programs from unnecessary dilution. BVF IS AMENDING ALL ITS 13-D FILINGS WITH THIS NOTICE. ITEM 5. INTEREST IN SECURITIES OF THE ISSUER.
