 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: 
 1. If the Company solicits approval of its stockholders of a Business Combination, the undersigned will vote all Insider
Shares owned by the undersigned in accordance with the majority of the votes cast by the holders of the IPO Shares. The undersigned will not vote in favor of any amendment to Article Fifth and Sixth of the Amended and Restated Certificate of
Incorporation of the Company proposed to be filed with the Secretary of State of the State of Delaware on the Effective Date. 
 2. In the event that the

Transfer & Trust Company, as Trustee (the “Trust Agreement”); and (ii) cause the Company to liquidate as soon as reasonably practicable. The undersigned agrees that in connection with any cessation of the corporate
existence of the Company, it will take all reasonable steps to cause the Company to adopt a plan of distribution in accordance with Section 281(b) of the General Corporation Law of the State of Delaware or any successor provision thereto. 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 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. The undersigned
acknowledges and agrees that there will be no distribution from the Trust Account with respect to any warrants, all rights of which will terminate on the Company’s liquidation. 
 3. Except as disclosed in the Registration Statement, neither the undersigned nor any Affiliate of the undersigned will be entitled to receive and will not accept any compensation for services rendered to the Company
prior to or in connection with the consummation of the Business Combination; provided, that the undersigned shall be entitled to reimbursement from the Company upon approval by the Company’s Audit Committee for the undersigned’s reasonable
out-of-pocket expenses incurred in connection with seeking and consummating a Business Combination. 
 4. Neither the undersigned nor any Affiliate of the
undersigned will be entitled to receive or accept from the Company a finder’s fee, broker commission or any other compensation in the event the undersigned or any Affiliate of the undersigned originates a Business Combination.
