The undersigned intends to purchase 3,000,000 Units in the IPO. Certain capitalized terms used herein are defined in paragraph 6 hereof.

In order to induce the Company and the Underwriter to enter into the Underwriting Agreement and to proceed with the IPO, and in recognition of the benefit that such IPO will confer upon the undersigned as a stockholder of the Company, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the undersigned hereby agrees with the Company and the Underwriter as follows:

2. If the Company solicits approval of its stockholders of a Business Combination, the undersigned will vote all shares of Common Stock acquired in the IPO in favor of such Business Combination.

3. The undersigned hereby waives his, her or its right to exercise redemption rights, as described in the Registration Statement, in connection with a Business Combination with respect to the Restricted Shares, and agrees that he, she or it will not seek redemption with respect to such Restricted Shares in connection with any vote on a Business Combination with respect thereto.
