Section 3. Representations and Warranties of the Sponsor.

     As a material inducement to the Company to enter into this Agreement and issue and sell the Sponsor Warrants to the Sponsor, the Sponsor hereby represents and warrants to the Company (which representations and warranties shall survive the Closing Date) that:

     A. Organization and Requisite Authority. The Sponsor is a limited partnership duly organized, validly existing and in good standing under the laws of the State of Delaware. The Sponsor possesses all requisite power and authority necessary to carry out the transactions contemplated by this Agreement.

     B. Authorization; No Breach.

          (i) This Agreement constitutes a valid and binding obligation of the Sponsor, enforceable in accordance with its terms, subject to bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other laws of general applicability relating to or affecting creditors’ rights and to general equitable principles (whether considered in a proceeding in equity or law).

          (ii) The execution and delivery by the Sponsor of this Agreement and the fulfillment of and compliance with the terms hereof by the Sponsor does not and shall not as of the Closing Date conflict with or result in a breach of the terms, conditions or provisions of the organizational documents of the Sponsor or any other agreement, instrument, order, judgment or decree to which the Sponsor is subject.

     C. Investment Representations.

          (i) The Sponsor is acquiring the Sponsor Warrants and, upon exercise of the Sponsor Warrants, the Shares issuable upon such exercise (collectively, the “Securities”) for its own account, for investment purposes only and not with a view towards, or for resale in connection with, any public sale or distribution thereof.

          (ii) The Sponsor is an “accredited investor” as such term is defined in Rule 501(a)(3) of Regulation D.

          (iii) The Sponsor understands that the Securities are being offered and will be sold to it in reliance on specific exemptions from the registration requirements of the United States federal and state securities laws and that the Company is relying upon the truth and accuracy of, and the Sponsor’s compliance with, the representations and warranties of the Sponsor set forth herein in order to determine the availability of such exemptions and the eligibility of the Sponsor to acquire such Securities.

          (iv) The Sponsor did not decide to enter into this Agreement as a result of any general solicitation or general advertising within the meaning of Rule 502(c) under the Securities Act of 1933, as amended (the “Securities Act”).

          (v) The Sponsor has been furnished with all materials relating to the business, finances and operations of the Company and materials relating to the offer and sale of the Securities which have been requested by the Sponsor. The Sponsor has been afforded the opportunity to ask questions of the executive officers and directors of the Company. The Sponsor understands that its investment in the Securities involves a high degree of risk and it has sought such accounting, legal and tax advice as it has considered necessary to make an informed investment decision with respect to the acquisition of the Securities.

          (vi) The Sponsor understands that no United States federal or state agency or any other government or governmental agency has passed on or made any recommendation or endorsement of the Securities or the fairness or suitability of the investment in the Securities by the Sponsor nor have such authorities passed upon or endorsed the merits of the offering of the Securities.

          (vii) The Sponsor understands that: (a) the Securities have not been and are not being registered under the Securities Act or any state securities laws, and may not be offered for sale, sold, assigned or transferred unless (1) subsequently registered thereunder or (2) sold in reliance on an exemption therefrom; and (b) except as specifically set forth in the Registration Rights Agreement, neither the Company nor any other person is under any obligation to register the Securities under the Securities Act or any state securities laws or to comply with the terms and conditions of any exemption thereunder. In this regard, the Sponsor understands that the Securities and Exchange Commission has taken the position that promoters or affiliates of a blank check company and their transferees, both before and after a Business Combination, are deemed to be “underwriters” under the Securities Act when reselling the securities of a blank check company. Based on that position, Rule 144 adopted pursuant to the Securities Act would not be available for resale transactions of the Securities despite technical compliance with the requirements of such Rule, and the Securities can be resold only through a registered offering or in reliance upon another exemption from the registration requirements of the Securities Act.

          (viii) The Sponsor has such knowledge and experience in financial and business matters, knows of the high degree of risk associated with investments in the securities of companies in the development stage such as the Company, is capable of evaluating the merits and risks of an investment in the Securities and is able to bear the economic risk of an investment in the Securities in the amount contemplated hereunder for an indefinite period of time. The Sponsor has adequate means of providing for it or his/her current financial needs and contingencies and will have no current or anticipated future needs for liquidity which would be jeopardized by the investment in the Securities. The Sponsor can afford a complete loss of its or his investment in the Securities.
