Entry into a Material Definitive Agreement. On September 21, 2004, VaxGen, Inc. (the "Company") entered into two separate Warrant Exchange Agreements (each an "Agreement" and together the "Agreements") with the holders of warrants to purchase common stock of the Company (the "Common Stock"), which were issued in connection with the Company's Series A 6% Cumulative Convertible Preferred Stock Financing (the "Series A Warrants"), completed in May of 2001. One Agreement was entered into between the Company and Societe Generale, Kepler Capital, LLC, Cheyenne LLC and Prism Capital 5, L.P., who were all holders of the Series A Warrants (the "Series A Warrant Holders"). A separate Agreement was entered into between the Company and CD Investment Partners, Ltd. (together with the Series A Warrant Holders, the "Warrant Holders"), who was also a holder of a Series A Warrant. Pursuant to the Agreements, the Warrant Holders exchanged their Series A Warrants for two new series of warrants to purchase the Common Stock. In exchange for the Series A Warrants, which were exercisable for a total of 655,078 shares of Common Stock, the Company issued to the Warrant Holders, warrants to purchase a total of 1,146,388 shares of Common Stock, exercisable until September 21, 2005, at an exercise price of $0.01 per share (the "2005 Warrants"), and warrants to purchase a total of 655,078 shares of Common Stock, exercisable until September 21, 2007, at an exercise price of $16.00 per share (the "2007 Warrants", together with the 2005 Warrants, the "Exchange Warrants"). In connection with the execution of the Agreements, and the transactions contemplated thereby, the Company and the Warrant Holders also terminated the agreements entered into in connection with the Series A Warrants. Item 1.02. Termination of a Material Definitive Agreement. In connection with the transactions described in Item 1.01 above, the Company and the Warrant Holders canceled the Series A Warrants, which were exercisable for a total of 655,078 shares at an exercise price of $11.449 per share and redeemable for cash at 120% of the number of shares exercisable multiplied by the difference between the highest price between the event triggering redemption and the actual redemption and the exercise price. In addition, the Company and the Warrant Holders terminated that certain Registration Rights Agreement, dated May 23, 2001 (the "Registration Agreement") and that certain Securities Purchase Agreement, dated May 23, 2001 (the "Purchase Agreement"), each entered into in connection with the Series A 6% Cumulative Convertible Preferred Stock Financing. In connection with the termination of these agreements and the cancellation of the Series A Warrants, all of the Company's and the Warrant Holders' rights and obligations under the Series A Warrants, the Registration Agreement and the Purchase Agreement, respectively, were terminated, including without limitation, any rights to cash penalty payments, rights of redemption or registration rights. Item 3.02. Unregistered Sales of Equity Securities. As described in Item 1.01 above, the Company issued the Exchange Warrants to the Warrant Holders in exchange for the Series A Warrants. Neither the Exchange Warrants or the shares of the Common Stock issuable upon exercise thereof were registered under the Securities Act of 1933 (the "Act"). The Company issued the Exchange Warrants in a transaction exempt from the registration requirements of the Act by virtue of the exemption provided for in Section 3(a)(9) of the Act. As of the date of execution of the Agreements, the shares underlying the warrants may be freely tradeable under Rule 144(k) of the Act.
