4. Representations, Warranties and Agreements of the Purchasers. Each Purchaser severally for itself, and not jointly with the other Purchasers, represents and warrants to, and agrees with, the Company as follows:

4.1 Authorization. Such Purchaser has all requisite power under its constituent documents to enter into each of this Agreement and the Registration Rights Agreement and to carry out and perform its obligations under the terms of this Agreement and the Registration Rights Agreement. All action on the part of such Purchaser and, if applicable, its officers, directors, stockholders, managers, members and equityholders necessary for the authorization, execution, delivery and performance of this Agreement and the Registration Rights Agreement and the consummation of the transactions contemplated herein and therein has been taken. When executed and delivered, each of this Agreement and the Registration Rights Agreement will constitute the legal, valid and binding obligation of such Purchaser, enforceable against such Purchaser in accordance with its terms, except as such may be limited by bankruptcy, insolvency, reorganization or other laws affecting creditors’ rights generally and by general equitable principles.

4.2 Purchase Entirely for Own Account. Such Purchaser is acquiring the Shares being purchased by it hereunder for investment, for its own account, and not for resale or with a view to distribution thereof in violation of the Securities Act.

4.3 Investor Status; Etc. Such Purchaser certifies and represents to the Company that at the time such Purchaser acquires any of the Shares, such Purchaser will be an “Accredited Investor” as defined in Rule 501 of Regulation D promulgated under the Securities Act and was not organized for the purpose of acquiring the Shares. Such Purchaser’s financial condition is such that it is able to bear the risk of holding the Shares for an indefinite period of time and the risk of loss of its entire investment. Such Purchaser has sufficient knowledge and experience in investing in companies similar to the Company in terms of the Company’s stage of development so as to be able to evaluate the risks and merits of its investment in the Company. Such

10

Purchaser has received and carefully reviewed descriptive materials relating to the Company and any other materials relating thereto that such Purchaser has requested. Such Purchaser has had an opportunity to ask questions of and receive answers from the authorized representatives of the Company, and to review any relevant documents and records concerning the business of the Company and the terms and conditions of this investment, and that any such questions have been answered to such Purchaser’s full satisfaction. No Person other than the Company or its authorized representatives, has offered the securities to the Purchaser. Such Purchaser is acquiring the Shares in the ordinary course of business for such Purchaser’s own account as principal (and not as a nominee or agent), for investment purposes only, and not with a view to, or for, resale, distribution or fractionalization thereof, in whole or in part, in any manner in violation of applicable United States federal or state securities laws or the rules or regulations promulgated thereunder. Such Purchaser has made no agreement, direct or indirect, with any other Person regarding any sale, transfer, assignment or other disposition of any interest in the Shares. Such Purchaser is aware that, in the view of the SEC and certain state securities commissions, a purchase of the Shares now with an intent to resell by reason of any foreseeable specific contingency or anticipated change in market values or any change in the condition of the Company, or in connection with a contemplated liquidation or settlement of any loan obtained for the acquisition of the Shares and for which the Shares were pledged as security, would represent an intent inconsistent with this representation. Such Purchaser further represents and agrees that if, contrary to the foregoing intentions, such Purchaser should later desire to dispose of or transfer any of the Shares in any manner, such Purchaser shall not do so without first complying with the provisions of Section 6.1. Such Purchaser understands that no federal or state agency has passed upon or made any recommendation or endorsement of an investment in the Shares. The foregoing shall in no way limit or modify the representations of the Company set forth in Section 3 hereof.

4.4 Shares Not Registered. Such Purchaser understands that the Shares have not been registered under the Securities Act, by reason of their issuance by the Company in a transaction exempt from the registration requirements of the Securities Act, and that the Shares must continue to be held by such Purchaser unless a subsequent disposition thereof is registered under the Securities Act or is exempt from such registration.

6.1 Securities Law Transfer Restrictions. No Purchaser shall sell, assign, pledge, transfer or otherwise dispose or encumber any of the Shares being purchased by it hereunder, except: (i) pursuant to an effective registration statement under the Securities Act or (ii) pursuant to an available exemption from registration under the Securities Act and applicable state securities laws and, if reasonably requested by the Company, upon delivery by such Purchaser of an opinion of counsel reasonably satisfactory to the Company to the effect that the proposed transfer is exempt from registration under the Securities Act and applicable state securities laws. Any transfer or purported transfer of the Shares in violation of this Section 6.1 shall be voidable by the Company; provided, however, that no opinion will be required in connection with (1) a public sale or transfer of Shares pursuant to an effective registration statement in connection with which such Purchaser represents in writing to the Company that such Shares have been or are being sold pursuant to such registration statement; (2) a public sale of Shares pursuant to Rule 144 under the Securities Act if such Purchaser has delivered to the Company a customary and accurate Rule 144 broker’s and seller’s representation letter; or (3) a sale of shares pursuant to Rule 144(k) under the Securities Act if such Purchaser has delivered to the Company a customary and accurate Rule 144 seller’s representation letter.

The Company may, and may instruct any transfer agent for the Company, to place such stop transfer orders as may be required on the transfer books of the Company in order to ensure compliance with the provisions of this Section 6.1.

15

6.2 Legends. Each certificate representing any of the Shares shall be endorsed with a legend in substantially the form set forth below, and each Purchaser covenants that, except to the extent such restrictions are waived by the Company, it shall not transfer the shares represented by any such certificate without complying with the restrictions on transfer described in this Agreement and the legends endorsed on such certificate:

THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR THE SECURITIES LAWS OF ANY STATE AND MAY ONLY BE OFFERED, SOLD, ASSIGNED, PLEDGED, TRANSFERRED OR OTHERWISE DISPOSED OF PURSUANT TO (I) AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT AND SUCH LAWS OR (II) AN EXEMPTION FROM REGISTRATION UNDER SAID ACT, AND TO THE EXTENT PERMITTED BY SECTION 6.1 OF THE COMMON STOCK PURCHASE AGREEMENT PURSUANT TO WHICH THE SHARES REPRESENTED HEREBY WERE ACQUIRED, UPON DELIVERY OF AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY THAT THE PROPOSED TRANSFER IS EXEMPT FROM THE ACT AND SUCH LAWS.

6.3 Removal of Legends. Upon the earlier of (i) the effectiveness of the Registration Statement (as defined in the Registration Rights Agreement) covering resale of the Shares under the Securities Act or (ii) the Shares becoming eligible for resale under Rule 144(k) promulgated under the Securities Act, the Company shall (A) deliver to the transfer agent for the Common Stock (the “Transfer Agent”) irrevocable instructions that the Transfer Agent shall reissue a certificate representing the Shares without legends upon receipt by such Transfer Agent of the legended certificates for such Shares, together with either (1) a customary representation by the applicable Purchaser that Rule 144(k) promulgated under the Securities Act applies to the Shares represented thereby or (2) a statement by the Purchaser that such Purchaser has sold the Shares represented thereby in accordance with the Plan of Distribution contained in the Registration Statement, and (B) cause its counsel to deliver to the Transfer Agent one or more blanket opinions to the effect that the removal of such legends in such circumstances may be effected under the Securities Act. From and after the earlier of such dates, upon a Purchaser’s written request, the Company shall promptly cause certificates evidencing the Purchaser’s Shares to be replaced with certificates which do not bear such restrictive legends. When the Company is required to cause unlegended certificates to replace previously issued legended certificates, if unlegended certificates are not delivered to a Purchaser within five (5) business days of submission by that Purchaser of legended certificate(s) to the Transfer Agent as provided above, the Company shall be liable to the Purchaser for liquidated damages in an amount equal to 1.0% of the aggregate purchase price of the Shares evidenced by such certificate(s) for each thirty (30) day period (pro rated for any period of less than 30 days) beyond such five (5) business days that the unlegended certificates have not been so delivered.

7. Termination; Liabilities Consequent Thereon. This Agreement may be terminated and the transactions contemplated hereunder abandoned at any time prior to the Closing only as follows:

(d) with respect to a Purchaser, by such Purchaser, if there has been any breach of any representation or warranty or any material breach of any covenant of the Company contained herein and the same has not been cured within 15 days after notice thereof (it being understood and agreed by each Purchaser that, in the case of any representation or warranty of the Company contained herein which is not hereinabove qualified by application thereto of a materiality standard, such representation or warranty will be deemed to have been breached for purposes of this Section 7.1(d) only if such representation or warranty was not true and correct in all material respects at the time such representation or warranty was made by the Company); or

(e) by the Company with respect to a Purchaser, if there has been any breach of any representation, warranty or any material breach of any covenant of such Purchaser contained herein and the same has not been cured within 15 days after notice thereof (it being understood and agreed by the Company that, in the case of any representation and warranty of the Purchaser contained herein which is not hereinabove qualified by application thereto of a materiality standard, such representation or warranty will be deemed to have been breached for purposes of this Section 7.1(e) only if such representation or warranty was not true and correct in all material respects at the time such representation or warranty was made by such Purchaser).

Any termination pursuant to this Section 7 shall be without liability on the part of any party, unless such termination is the result of a material breach of this Agreement by a party to this Agreement in which case such breaching party shall remain liable for such breach notwithstanding any termination of this Agreement.
