declared effective (the “Effective Date”) and continuing until the earlier of the consummation by the Company of an initial business combination or the Company’s liquidation (in each case as described in the Registration Statement)
(such earlier date hereinafter referred to as the “Termination Date”): 
 (i) The Sponsor shall make available, or cause to be made
available, to the Company, at 2870 Peachtree Road, NW Suite 509, Atlanta, Georgia 30305 (or any successor location of the Sponsor), certain office space, utilities and secretarial and administrative support as may be reasonably required by the
Company. In exchange therefor, the Company shall pay the Sponsor the sum of $10,000 per month beginning on the Effective Date and continuing monthly thereafter until the Termination Date; and 

(ii) The Sponsor hereby irrevocably waives any and all right, title, interest, causes of action and claims of any kind as a result of, or
arising out of, this letter agreement (each, a “Claim”) in or to, and any and all right to seek payment of any amounts due to it out of the trust account established for the benefit of the public stockholders of the Company and into which
substantially all of the proceeds of the Company’s initial public offering will be deposited (the “Trust Account”) as a result of, or arising out of, this letter agreement, and hereby irrevocably waives any Claim it may have in the

Trust Account or any monies or other assets in the Trust Account for any reason whatsoever. 
 This letter agreement constitutes the entire

particular provision, except by a written instrument executed by the parties hereto. 
 No party hereto may assign either this letter
agreement or any of its rights, interests, or obligations hereunder without the prior written approval of the other party. Any purported assignment in violation of this paragraph shall be void and ineffectual and shall not operate to transfer or
assign any interest or title to the purported assignee.
