Re: Advisory Services Agreement


 


Ladies and Gentlemen:


 


This letter agreement by and between Thunder Bridge
Capital Partners IV Inc. (the “Company”) and Thunder Bridge Capital, LLC (“TBC”), 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)    TBC, an affiliate of
the Company’s Chief Executive Officer, shall provide advisory services relating to the Company’s search for and consummation
of an initial business combination. In exchange therefor, the Company shall pay TBC the sum of $20,000 per month commencing on the Listing
Date, and will be entitled to be reimbursed for any out-of-pocket expenses, continuing monthly thereafter until the Termination Date;
and


 


(ii)     TBC 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.
