Certain capitalized terms used herein are defined in paragraph 10 hereof.

In order to induce the Company and the Underwriters 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 Underwriters as follows:

The undersigned hereby waives any and all right, title, interest or claim of any kind (each a “Claim”) in or to (x) any distribution of the Trust Account with respect to the undersigned’s Insider Shares (other than the undersigned’s Private Placement Units) in connection with a liquidation and (y) any remaining net assets of the Company after such liquidation. The undersigned hereby waives any Claim the undersigned may have in the future as a result of, or arising out of, any contracts or agreements with the Company and will not seek recourse against the funds held in or distributed from the Trust Account for any reason (other than with respect to the undersigned’s Private Placement Units or with respect to reimbursement of reasonable out-of-pocket expenses
