NOW, THEREFORE, in order to implement the foregoing and in consideration of the mutual agreements contained herein and the Original Agreement, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Company and the other parties hereto, intending to be legally bound hereby, agree as follows: 1. Section 1. The following definition is hereby added to Section 1 of the Original Agreement, following the definition of "Selling Expenses": ""Series F Preferred Stock" shall mean the Company's Series F Convertible Preferred Stock, $0.001 par value per share." 2. Section 4(b). The parenthetical "(for both sections)" in Section 4(b) of the Original Agreement is hereby deleted. 3. Section 4(c). Section 4(c) of the Original Agreement is hereby amended and restated in its entirety as follows: "The Company may include in any registration requested pursuant to this Section 4 hereof any shares of Common Stock for sale for its own account or for the account of any other person entitled to "piggy-back" or "incidental rights" as of September 9, 2003, provided that such inclusion shall not affect the number of Restricted Stock that can be sold in the related offering. In connection with an underwritten offering, if the managing underwriter advises the Company in writing that in its opinion the number of Restricted Stock requested by the holders of Restricted Stock to be registered exceeds the number which can be sold in such offering, the Company shall include in such registration statement the number of Restricted Stock that, in the EXECUTION COPY opinion of the managing underwriter, can be sold as follows: (i) first, the Restricted Stock requested to be registered, pro rata among the holders of Restricted Stock that have requested their Restricted Stock to be registered, (ii) second, Common Stock requested to be registered by holders of existing registration rights on September 9, 2003 and (iii) third, any other Common Stock requested to be included in such registration." 4.

The penultimate sentence of Section 5(a) of the Original Agreement is hereby amended and restated in its entirety to read as follows: "Notwithstanding the provisions of this Section 5(a), if the registration was initiated by the Company at the request of a person or persons entitled to demand rights as of September 9, 2003 exercising such demand rights, priority in underwriter cutbacks with respect to such registration shall be governed by the provisions of their particular agreement providing for such demand rights, provided that the holders of Restricted Stock that have requested inclusion of their Restricted Stock to be included therein shall be pari passu with the holders of Series F Preferred Stock, if any, who have exercised their rights to incidental registration under Section 5 of the Registration Rights Agreement dated as of September 9, 2003, among the Company and the investors named therein (pro rata among the requesting holders based upon the number of shares of Restricted Stock owned by such holders and the shares of Common Stock issuable upon conversion of the Series F Preferred Stock held by holders of such securities) and have priority over any other persons holding securities requested to be included in such registration." 6. Effect of First Amendment. In all other respects, the Original Agreement, as amended hereby, remains in full force and effect as written. 7. Counterparts.
