instructed by the Company to do so; 
 (h) Render to the Company monthly written statements of the activities of, and amounts in, the Trust

 (i) Commence liquidation of the Trust Account only after and

signed on behalf of the Company by its Chief Executive Officer, Chief Financial Officer, President, Chairman (or Co-Chairman) of the Board of Directors (the “Board”), Secretary or other authorized
officer of the Company and, in the case of a Termination Letter in a form substantially similar to that attached hereto as Exhibit A, acknowledged and agreed to by the Representative, and complete the liquidation of the Trust Account and
distribute the Property in the Trust Account, including interest not previously released to the Company to pay its taxes only as directed in the Termination Letter and the other documents referred to therein; provided, however, that in
the event that a Termination Letter has not been received by the Trustee by the date which is later than (i) the 12 month anniversary of the closing of the IPO (“Initial Business Combination Period”), (ii) up to the 18 month
anniversary of the closing of the IPO if the period to complete a Business Combination is extended by the Board of Directors of the Company pursuant to the Company’s Amended and Restated Certificate of Incorporation, or (iii) such later
date as may be approved (prior to the expiration of the Initial Business Combination Period) by the Company’s stockholders in accordance with the Company’s Amended and Restated Certificate of Incorporation, as the same may be amended from
time to time, the Trust Account shall be liquidated in accordance with the procedures set forth in the Termination Letter attached as Exhibit B hereto and the Property in the Trust Account, including interest earned on the funds held in the

payment to the relevant taxing authority; provided, however, that to the extent there is not sufficient cash in the Trust Account to pay such tax obligation, the Trustee shall liquidate such assets held in the Trust Account as shall be
designated by the Company in writing to make such distribution, so long as there is no reduction in the principal amount per share initially deposited in the Trust Account; provided, further, that if the tax to be paid is a franchise
tax, the written request by the Company to make such distribution shall be accompanied by a copy of the franchise tax bill from the State of Delaware for the Company (it being acknowledged and agreed that any such amount in excess of interest income
earned on the Property shall not be payable from the Trust Account). The written request of the Company referenced above shall constitute presumptive evidence that the Company is entitled to said funds, and the Trustee shall have no responsibility
to look beyond said request;

 (k) Upon written request from the Company, which may be given from time to time in a form

Letter on or prior to the Applicable Deadline, to follow the instructions set forth in the Extension Letter.;
 (n) Promptly acknowledge, in
writing to any redeeming Public Stockholder and the Company, any irrevocable instruction letter in the form of Exhibit D delivered by such redeeming Public Stockholder after the announcement by the Company of the consummation of proposed
Business Combination and promptly comply with any irrevocable written instruction letter in the form of Exhibit D delivered by such Public Stockholder in connection with the disbursement of funds to such Public Stockholder if the Company has
not notified the Trustee in writing during the Objection Period that such irrevocable written instruction letter is not in compliance with the requirements set forth in this Agreement for redemption of a Public Stockholders shares of Common
Stock ; and

businesses or entities (a “Business Combination”), or pursuant to Section 2(b). The Company shall pay the Trustee the initial acceptance fee and first year’s fee at the consummation of the IPO and thereafter on the anniversary of

Section 2(b); or

and to transfer the proceeds to a segregated account held by you on behalf of the Beneficiaries to the effect that, on the Consummation Date, all of the funds held in the Trust Operating Account at J.P. Morgan Chase Bank, N.A. will be immediately
available for transfer to the account or accounts that the Company shall direct on the Consummation Date (including as directed to it by the Representative on behalf of the Underwriters (with respect to the Deferred Discount). It is acknowledged and
agreed that while the funds are on deposit in the trust account at J.P. Morgan Chase Bank, N.A. awaiting distribution, the Company will not earn any interest or dividends .
