In such capacity, XAM possesses the power to vote and direct the disposition of all securities held by Xmark LP and Xmark Ltd. As of February 23, 2005, Xmark LP is the holder of 50,337 shares (the "Xmark LP Preferred") of the Series A-1 Preferred Stock, par value $0.001 per share (the "Preferred Stock") of Aerogen, Inc., a Delaware corporation (the "Company"), which are presently convertible into 503,370 shares of the Company's common stock, par value $0.001 per share (the "Common Stock"). As of February 23, 2005, Xmark Ltd is the holder of 62,996 shares (the "Xmark Ltd Preferred") of Preferred Stock, which are presently convertible into 629,960 shares of Common Stock. The terms of the Xmark LP Preferred and the Xmark Ltd Preferred originally precluded each of Xmark LP and Xmark Ltd from converting the Xmark LP Preferred and the Xmark Ltd Preferred if the conversion thereof would result in Xmark LP, Xmark Ltd and/or their affiliates beneficially owning in excess of 4.99% of the Company's outstanding Common Stock following any such conversion (the "Issuance Limitation"). Each such Issuance Limitation was waivable by Xmark LP and Xmark Ltd, respectively, providing 61 days' advance written notice to the Company. On November 3, 2004, Xmark LP and Xmark Ltd each provided a written waiver of the Issuance Limitation to the Company with respect to the Xmark LP Preferred and the Xmark Ltd Preferred. As a result of this waiver and as a result of the fact that XAM possesses the sole power to vote and direct the disposition of the securities described above, for purposes of Reg. Section 240.13d-3, XAM may be deemed to beneficially own 1,133,330 shares of Common Stock, or approximately 18.8% of the shares of Common Stock deemed issued and outstanding as of February 23, 2005. Item 5. Interest in Securities of the Issuer. ------------------------------------ Item 5 of the Schedule 13D is hereby amended and restated in its entirety as follows: Based on information reported by the Company in its Form 10-Q for the fiscal quarter ended September 30, 2004, filed with the Securities and Exchange Commission on November 15, 2004, there were 4,884,829 shares of Common Stock outstanding as of November 5, 2004. As of February 23, 2005, Xmark LP is the holder of 50,337 shares (the "Xmark LP Preferred") of the Series A-1 Preferred Stock, par value $0.001 per share (the "Preferred Stock") of Aerogen, Inc., a Delaware corporation (the "Company"), which are presently convertible into 503,370 shares of the Company's common stock, par value $0.001 per share (the "Common Stock"). As of February 23, 2005, Xmark Ltd is the holder of 62,996 shares (the "Xmark Ltd Preferred") of Preferred Stock, which are presently convertible into 629,960 shares of Common Stock. The terms of the Xmark LP Preferred and the Xmark Ltd Preferred preclude each of Xmark LP and Xmark Ltd from converting the Xmark LP Preferred and the Xmark Ltd Preferred if the conversion thereof would result in Xmark LP, Xmark Ltd and/or their affiliates beneficially owning in excess of 4.99% of the Company's outstanding Common Stock following any such conversion (the "Issuance Limitation"). Each such Issuance Limitation is waivable by Xmark LP and Xmark Ltd, respectively, providing 61 days' advance written notice to the Company. On November 3, 2004, Xmark LP and Xmark Ltd each provided a written waiver of the Issuance Limitation to the Company with respect to the Xmark LP Preferred and the Xmark Ltd Preferred. As a result of this waiver and as a result of the fact that XAM possesses the sole power to vote and direct the disposition of the securities described above, for purposes of Reg. Section 240.13d-3, XAM may be deemed to beneficially own 1,133,330 shares of Common Stock, or approximately 18.8% of the shares of Common Stock deemed issued and outstanding as of February 23, 2005. During the sixty days prior to February 23, 2005, there were no transactions in Common Stock, or securities convertible into, exercisable for or exchangeable for Common Stock, by XAM or any person or entity controlled by XAM or any person or entity for which XAM possesses voting or investment control over the securities thereof, except that Xmark LP and Xmark Ltd sold: (1) on January 19, 2005, warrants to purchase up to an aggregate of 1,666,660 shares of the Company's Common Stock for an aggregate purchase price of $383,331.80; (2) on January 24, 2005, 53,333 shares of the Company's Preferred Stock for an aggregate purchase price of $960,000.00, in each case, as more fully described in Item 6 of this Amendment No. 1 to Schedule 13D; and (3) on February 23, 2005, 91,309 shares of Common Stock for an aggregate purchase price of $164,355.48.
