Re: Administrative Services Agreement


 


Ladies and Gentlemen:


 


This letter agreement by and between Thunder Bridge
Capital Partners IV Inc. (the “Company”) and First Capital Group, LLC (“First Capital”), dated as
of the date hereof, will confirm our agreement that, commencing on the date the securities of the Company are first listed on the NASDAQ
Capital Market (the “Listing Date”), pursuant to a Registration Statement on Form S-1 and prospectus
filed with the Securities and Exchange Commission (the “Registration Statement”) and continuing until the earlier of
(a) the consummation by the Company of an initial business combination or (b) the Company’s liquidation (in each case as described
in the Registration Statement) (such earlier date hereinafter referred to as the “Termination Date”):


 


(i) First Capital, an affiliate
of the Company’s Chief Executive Officer, shall make available, or cause to be made available, to the Company, at 9912 Georgetown
Pike, Suite D203, Great Falls, Virginia 22066 (or any successor location of First Capital), office space and administrative and support
services. In exchange therefor, the Company shall pay First Capital the sum of $10,000 per month on the Listing Date and continuing monthly
thereafter until the Termination Date; and


 


(ii)  First Capital
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 shareholders of the Company and into which substantially all of the proceeds
of the Company’s initial public offering will be deposited (the “Trust Account”), and hereby irrevocably waives
any Claim it may have in the future, which Claim would reduce, encumber or otherwise adversely affect the Trust Account or any monies
or other assets in the Trust Account, and further agrees not to seek recourse, reimbursement, payment or satisfaction of any Claim against
the Trust Account or any monies or other assets in the Trust Account for any reason whatsoever.


 


This letter agreement constitutes the entire agreement
and understanding of the parties hereto in respect of its subject matter and supersedes all prior understandings, agreements, or representations
by or among the parties hereto, written or oral, to the extent they relate in any way to the subject matter hereof or the transactions
contemplated hereby.


 


This letter agreement may not be amended, modified
or waived as to any 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.


 


This letter agreement constitutes the entire relationship
of the parties hereto, and any litigation between the parties (whether grounded in contract, tort, statute, law or equity) shall be governed
by, construed in accordance with, and interpreted pursuant to the laws of the State of New York, without giving effect to its choice of
laws principles.


 


This letter agreement may be executed in one or
more counterparts, each of which shall for all purposes be deemed to be an original but all of which together shall constitute one and
the same letter agreement.
