C. Investment Representations.

(iii) The Purchaser 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 Purchaser’s compliance with, the representations and warranties of the Purchaser set forth herein in order to determine the availability of such exemptions and the eligibility of the Purchaser to acquire such Securities.

(iv) The Purchaser did not 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.

(v) The Purchaser 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 Purchaser. The Purchaser has been afforded the opportunity to ask questions of the executive officers and directors of the Company. The Purchaser 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 Purchaser 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 Purchaser nor have such authorities passed upon or endorsed the merits of the offering of the Securities.

The Purchaser has adequate means of providing for its 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 Purchaser can afford a complete loss of its investments in the Securities.

(ix) The Purchaser acknowledges and agrees the certificates evidencing the Securities shall bear a restrictive legend (the “Legend”), in form and substance as set forth in Section 6 hereof, prohibiting the offer, sale, pledge or transfer of the securities, except (i) pursuant to an effective registration statement covering these securities under the Securities Act or (ii) pursuant to any other exemptions from the registration requirements under the Securities Act and such laws which, in the opinion of counsel for the Company, is available.

D. Restrictions on Transfer. The Purchaser acknowledges and understands the Units are being offered in a transaction not involving a public offering in the United States within the meaning of the Securities Act. The Securities have not been registered under the Securities Act, and, if in the future, it decides to offer, resell, pledge or otherwise transfer the Securities, such Securities may be offered, resold, pledged or otherwise transferred only (A) pursuant to an effective registration statement filed under the Securities Act, (B) pursuant to an exemption from registration under Rule 144 promulgated under the Securities Act (“Rule 144”), if available, or (C) pursuant to any other available exemption from the registration requirements of the Securities Act, and in each case in accordance with any applicable securities laws of any state or any other jurisdiction. It agrees that if any transfer of its Securities or any interest therein is proposed to be made, as a condition precedent to any such transfer, it may be required to deliver to the Company an opinion of counsel satisfactory to the Company. Absent registration or another available exemption from registration, it agrees it will not resell the Securities. It further acknowledges that because the Company is a shell company, Rule 144 may not be available to it for the resale of the Securities until the one year anniversary following consummation of the initial Business Combination (defined below) of the Company, despite technical compliance with the requirements of Rule 144 and the release or waiver of any contractual transfer restrictions.
