Both the SPA and all exhibits thereto are attached as Exhibit A hereto and are incorporated herein in their entirety by reference. Pursuant to the SPA, the Issuer issued in a private placement (a) 1,640,000 shares of the Company's Series A Convertible Preferred Stock (the "Preferred Stock") to the Series A Investors, as well as the reservation for issuance of 16,400,000 shares of the Company's Common Stock upon conversion of the Preferred Stock, and (b) warrants (the "Warrants") to purchase 2,050,000 shares of the Company's Common Stock and the reservation for issuance of 2,050,000 shares of the Company's Common Stock upon the exercise of such Warrants (together, the "Preferred Stock Financing"). The Preferred Stock has the rights, preferences and privileges set forth in the Certificate of Designations of Series A Convertible Preferred Stock as filed with the Secretary of State of the State of Delaware. The purchase price for the Preferred Stock was $25.00 per share. Each share of Preferred Stock is initially convertible into 10 shares of Common Stock at a fixed conversion price of $2.50 per share (subject to adjustment upon the occurrence of certain events including stock subdivisions, combinations, splits, stock dividends, capital reorganizations, or capital reclassifications of the Common Stock), at such holder's option at any time after the first anniversary of the closing of the Investors Rights Agreement among the Company, the Reporting Persons and the other investors named therein, dated as of July 8, 2003, a copy of which is attached hereto as Exhibit B and is incorporated herein in its entirety by reference (the "Investors Rights Agreement").

Pursuant to the Certificate of Designations and the Investors Rights Agreement, the Series A Investors, voting together as a separate class, have the right to designate two members of the Company's Board of Directors so long as at least 37.5% of the shares of Preferred Stock issued at the closing of the Preferred Stock Financing remain outstanding. If between 18.75% and 37.5% of the shares of Preferred Stock issued at the closing of the Preferred Stock Financing are outstanding, the Series A Investors, voting together as a separate class, have the right to designate one member of the Company's Board of Directors. If less than 18.75% of the shares of Preferred Stock issued at the closing of the Preferred Stock Financing are outstanding, the rights of the Series A Investors to vote separately for the election of directors shall terminate. Page 19 of 28 Pursuant to the terms of the Investors Rights Agreement, one director will be designated by the JPMP Reporting Persons and one director will be designated by the Baker Entities. The right of the JPMP Reporting Persons and the Baker Entities, as applicable, to designate a director terminates if the JPMP Reporting Persons or the Baker Entities, as applicable, hold less than 50% of the Preferred Stock (or Common Stock issued upon conversion thereof) purchased by it at the closing of the Preferred Stock Financing.
