4. Purchaser’s Representations, Warranties and Covenants.

(a) Investment Intention. The Purchaser represents and warrants that it is acquiring the Shares solely for its own account for investment and not with a view to or for sale in connection with any distribution thereof in any transaction or series of transactions that would be in violation of the securities laws of the United States or any state thereof. The Purchaser agrees that it will not, directly or indirectly, offer, transfer, sell, pledge, hypothecate or otherwise dispose of any of the Shares (or solicit any offers to buy, purchase or otherwise acquire or take a pledge of any Shares), except in compliance with the Securities Act of 1933, as amended (the “Securities Act”), and the rules and regulations of the Securities and Exchange Commission (the “Commission”) thereunder, and in compliance with applicable state securities or “blue sky” laws. The Purchaser further understands, acknowledges and agrees that none of the Shares may be transferred, sold, pledged, hypothecated or otherwise disposed of unless (i) (A) such disposition is pursuant to an effective registration statement under the Securities Act, (B) the Purchaser shall have delivered to the Company an opinion of counsel, which opinion and counsel shall be reasonably satisfactory to the Company, to the effect that such disposition is exempt from the provisions of Section 5 of the Securities Act, or (C) a no-action letter from the Commission, reasonably satisfactory to the Company, shall have been obtained with respect to such disposition and (ii) such disposition is pursuant to registration under any applicable state securities laws or an exemption therefrom.

(b) Legend. The Purchaser acknowledges that the certificate or certificates representing the Shares shall bear the following legend:

“THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR QUALIFIED UNDER ANY STATE SECURITIES LAWS AND MAY NOT BE TRANSFERRED, SOLD, PLEDGED, HYPOTHECATED OR OTHERWISE DISPOSED OF UNLESS (i) (A) SUCH DISPOSITION IS PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OF 1933, AS AMENDED, (B) THE HOLDER HEREOF SHALL HAVE DELIVERED TO THE COMPANY AN OPINION OF COUNSEL, WHICH OPINION AND COUNSEL SHALL BE REASONABLY SATISFACTORY TO THE COMPANY, TO THE EFFECT THAT SUCH DISPOSITION IS EXEMPT FROM THE PROVISIONS OF SECTION 5 OF SUCH ACT OR (C) A NO-ACTION LETTER FROM THE

SECURITIES AND EXCHANGE COMMISSION, REASONABLY SATISFACTORY TO COUNSEL FOR THE COMPANY, SHALL HAVE BEEN OBTAINED WITH RESPECT TO SUCH DISPOSITION AND (ii) SUCH DISPOSITION IS PURSUANT TO REGISTRATION UNDER ANY APPLICABLE STATE SECURITIES LAWS OR AN EXEMPTION THEREFROM.”

“THE SHARES REPRESENTED BY THIS CERTIFICATE ARE ENTITLED TO THE BENEFITS OF AND ARE BOUND BY THE OBLIGATIONS SET FORTH IN A REGISTRATION AND PARTICIPATION AGREEMENT, DATED AS OF APRIL 7, 2004, AMONG THE COMPANY AND CERTAIN STOCKHOLDERS OF THE COMPANY, A COPY OF WHICH IS LOCATED AT THE PRINCIPAL OFFICE OF THE COMPANY.”

(c) Securities Law Matters. The Purchaser acknowledges receipt of advice from the Company that (i) the Shares have not been registered under the Securities Act or qualified under any state securities or “blue sky” laws, (ii) it is not anticipated that there will be any public market for the Shares, (iii) the Shares must be held indefinitely and the Purchaser must continue to bear the economic risk of the investment in the Shares unless the Shares are subsequently registered under the Securities Act and such state laws or an exemption from registration is available, (iv) Rule 144 promulgated under the Securities Act (“Rule 144”) is not presently available with respect to the sales of any securities of the Company and the Company has made no covenant to make Rule 144 available, (v) when and if the Shares may be disposed of without registration in reliance upon Rule 144, such disposition can be made only in limited amounts in accordance with the terms and conditions of such Rule, if the Purchaser is deemed to be an “affiliate” of the Company within the meaning of Rule 144, (vi) the Company does not plan to file reports with the Commission or make public information concerning the Company available unless required to do so by law or by the terms of its financing agreements, (vii) if the exemption afforded by Rule 144 is not available, sales of the Shares may be difficult to effect because of the absence of public information concerning the Company, (viii) a restrictive legend in the form heretofore set forth shall be placed on the certificates representing the Shares and (ix) a notation shall be made in the appropriate records of the Company indicating that the Shares are subject to restrictions on transfer set forth in this Agreement and, if the Company should in the future engage the services of a stock transfer agent, appropriate stop-transfer restrictions will be issued to such transfer agent with respect to the Shares.

(d) Compliance with Rule 144. If any of the Shares are to be disposed of in accordance with Rule 144, the Purchaser shall transmit to the Company an executed copy of Form 144 (if required by Rule 144) no later than the time such form is required to be transmitted to the Commission for filing and such other documentation as the Company may reasonably require to assure compliance with Rule 144 in connection with such disposition.

(e) Ability to Bear Risk. The Purchaser represents and warrants that (i) the financial situation of the Purchaser is such that it can afford to bear the economic risk of holding the Shares for an indefinite period and (ii) the Purchaser can afford to suffer the complete loss of its investment in the Shares.

The Purchaser agrees that, in the event that the Company files a registration statement under the Securities Act with respect to an underwritten public offering of any shares of its capital stock, the Purchaser will not effect any public sale or distribution of any shares of the Common Stock (other than as part of such underwritten public offering) during the Holdback Period (as defined in the Registration and Participation Agreement).

5. Representations and Warranties of the Company. The Company represents and warrants to the Purchaser that (a) the Company has been duly incorporated and is in good standing under the laws of State of Delaware, (b) this Agreement has been duly authorized, executed and delivered by the Company and constitutes a valid and legally binding obligation of the Company enforceable against the Company in accordance with its terms, (c) the Shares, when issued and delivered in accordance with the terms hereof, will be duly authorized, validly issued, fully paid and nonassessable, and free and clear of any liens or encumbrances other than those created pursuant to this Agreement or otherwise in connection with the transactions contemplated hereby and (d) the authorized capital stock of the Company consists of 7,000,000 shares of Common
