NOW THEREFORE, IT IS AGREED:


 


1. Agreements and Covenants of Trustee.
The Trustee hereby agrees and covenants to:


 


(a) Hold the Property in trust for the Beneficiaries

of the Company, invest and reinvest the Property solely in United States government securities within the meaning of Section 2(a)(16)
of the Investment Company Act of 1940, as amended, having a maturity of 185 days or less, or in money market funds meeting the conditions
of Rule 2a-7(d) promulgated under the Investment Company Act of 1940, as amended (or any successor rule), which invest only in direct
U.S. government treasury obligations, as determined by the Company; it being understood that the Trust Account will earn no interest while
account funds are uninvested awaiting the Company’s instructions hereunder and the Trustee may earn bank credits or other consideration;


 






     


     


    




 


(d) Collect and receive, when due, all interest
or other income arising from the Property, which shall become part of the “Property,” as such term is used herein;


 


(e) Promptly notify the Company and the Representative
of all communications received by the Trustee with respect to any Property requiring action by the Company;


 


(f) Supply any necessary information or documents
as may be requested by the Company (or its authorized agents) in connection with the Company’s preparation of the tax returns relating
to assets held in the Trust Account or in connection with the preparation or completion of the audit of the Company’s financial
statements by the Company’s auditors;


 


(g) Participate in any plan or proceeding for
protecting or enforcing any right or interest arising from the Property if, as and when instructed by the Company to do so;


 


(h) Render to the Company monthly written statements
of the activities of, and amounts in, the Trust Account reflecting all receipts and disbursements of the Trust Account;


 


(i) Commence liquidation of the Trust Account
(x) only after and promptly after receipt of, and only in accordance with, the terms of a letter from the Company (“Termination Letter”)
in a form substantially similar to that attached hereto as either Exhibit A or Exhibit B, as applicable,
signed on behalf of the Company by either of its Chief Executive Officer, Chief Financial Officer, President, Executive Vice President,
Vice President, Secretary or Chairman of the board of directors of the Company (the “Board”) or other authorized
officer of the Company, and, in the case of a Termination Letter in a form substantially similar to the attached hereto as Exhibit
A, 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 (less up to $100,000 of interest that may be released to the Company to pay dissolution expenses),
only as directed in the Termination Letter and the other documents referred to therein, or (y) as promptly as reasonably possible following
the distribution of the Property in the Trust Account, including interest not previously released to the Company to pay its taxes (less
up to $100,000 of interest that may be released to the Company to pay dissolution expenses), to the Public Stockholders of record as of
such date, which such distribution shall occur as promptly as reasonably possible but not more than ten (10) business days after the date
which is the later of (1) twenty-four (24) months after the closing of the Offering or (2) such date as may be approved by the Company’s
stockholders in accordance with the Company’s amended and restated certificate of incorporation if a Termination Letter has not
been received by the Trustee prior to such date, in which case the Trust Account shall be liquidated in accordance with the procedures
set forth in the Termination Letter attached as Exhibit B.


 


(j) Upon written request from the Company, which
may be given from time to time in a form substantially similar to that attached hereto as Exhibit C, withdraw from the Trust
Account and distribute to the Company the amount of interest earned on the Property requested by the Company to cover any tax obligation
owed by the Company as a result of assets of the Company or interest or other income earned on the Property, which amount shall be delivered
directly to the Company by electronic funds transfer or other method of prompt payment, and the Company shall forward such 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 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 substantially similar to that attached hereto as Exhibit D, the Trustee shall distribute
on behalf of the Company the amount requested by the Company to be used to redeem shares of Common Stock from Public Stockholders properly
submitted in connection with a stockholder vote to approve an amendment to the Company’s amended and restated certificate of incorporation
to modify the substance or timing of the Company’s obligation to allow redemption in connection with an initial Business Combination
or to redeem one hundred percent (100%) of its public shares of Common Stock if the Company has not consummated an initial Business Combination
within such time as is described in clause (y) of Section 1(i) of the Agreement, or with respect to any other provision relating to stockholders’
rights or pre-initial Business Combination activity. The written request of the Company referenced above shall constitute presumptive
evidence that the Company is entitled to distribute said funds, and the Trustee shall have no responsibility to look beyond said request;
and

(l) Not make any withdrawals or distributions
from the Trust Account other than pursuant to Section 1(i), (j) or (k) above.


 


2. Agreements and Covenants of the Company.
The Company hereby agrees and covenants to:


 


(a) Give all instructions to the Trustee hereunder
in writing, signed by either of the Company’s Chairman of the Board, Chief Executive Officer, Chief Financial Officer, President,
Executive Vice President, Vice President or Secretary. In addition, except with respect to its duties under Sections 1(i), 1(j) and 1(k) hereof,
the Trustee shall be entitled to rely on, and shall be protected in relying on, any verbal or telephonic advice or instruction which it,
in good faith and with reasonable care, believes to be given by any one of the persons authorized above to give written instructions,
provided that the Company shall promptly confirm such instructions in writing;


 


(b) Subject to Section 4 hereof,
hold the Trustee harmless and indemnify the Trustee from and against any and all expenses, including reasonable counsel fees and disbursements,
or losses suffered by the Trustee in connection with any action taken by it hereunder and in connection with any action, suit or other
proceeding brought against the Trustee involving any claim, or in connection with any claim or demand, which in any way arises out of
or relates to this Agreement, the services of the Trustee hereunder, or the Property or any interest earned on the Property, except for
expenses and losses resulting from the Trustee’s gross negligence, fraud or willful misconduct. Promptly after the receipt by the
Trustee of notice of demand or claim or the commencement of any action, suit or proceeding, pursuant to which the Trustee intends to seek
indemnification under this Section 2(b), it shall notify the Company in writing of such claim (hereinafter referred to as
the “Indemnified Claim”). The Trustee shall have the right to conduct and manage the defense
against such Indemnified Claim; provided that the Trustee shall obtain the consent of the Company with respect to the
selection of counsel, which consent shall not be unreasonably withheld. The Trustee may not agree to settle any Indemnified Claim without
the prior written consent of the Company, which such consent shall not be unreasonably withheld. The Company may participate in such action
with its own counsel;


 


(c) Pay the Trustee the fees set forth on Schedule
A hereto, including an initial acceptance fee, annual administration fee, and transaction processing fee which fees shall be
subject to modification by the parties from time to time. It is expressly understood that the Property shall not be used to pay such fees
unless and until the closing of the Business Combination (defined below). The Company shall pay the Trustee the initial acceptance fee
and the first annual administration fee at the consummation of the Offering. The Trustee shall refund to the Company the annual administration
fee (on a pro rata basis) with respect to any period after the liquidation of the Trust Account. The Company shall not be responsible
for any other fees or charges of the Trustee except as set forth in this Section 2(c), Schedule A and as
may be provided in Section 2(b) hereof;


 


(d) In connection with any vote of the Company’s
stockholders regarding a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination
involving the Company and one or more businesses (the “Business Combination”), provide to
the Trustee an affidavit or certificate of the inspector of elections for the stockholder meeting verifying the vote of such stockholders
regarding such Business Combination;


 


(e) Provide the Representative with a copy of
any Termination Letter(s) and/or any other correspondence that is sent to the Trustee with respect to any proposed withdrawal from the
Trust Account promptly after it issues the same;


 






    3


     


    

 


(f) Unless otherwise agreed between the Company
and the Representative, ensure that any Instruction Letter (as defined in Exhibit A) delivered in connection with a Termination
Letter in the form of Exhibit A expressly provides that the applicable portions of the Deferred Discount is paid directly to the
account or accounts directed by each of the Representative on behalf of the Underwriters prior to any transfer of the funds held in the
Trust Account to the Company or any other person;


 


(g) Instruct the Trustee to make only those distributions
that are permitted under this Agreement, and refrain from instructing the Trustee to make any distributions that are not permitted under
this Agreement; and


 


(h) Within four (4) business days after the Underwriters
exercise the over-allotment option (or any unexercised portion thereof) or such over-allotment expires, provide the Trustee with a notice
in writing of the total amount of the Deferred Discount.


 


3. Limitations of Liability. The Trustee
shall have no responsibility or liability to:


 


(a) Imply obligations, perform duties, inquire
or otherwise be subject to the provisions of any agreement or document other than this Agreement and that which is expressly set forth
herein;


 


(b) Take any action with respect to the Property,
other than as directed in Section 1 hereof, and the Trustee shall have no liability to any third party except for liability
arising out of the Trustee’s gross negligence, fraud or willful misconduct;


 


(c) Institute any proceeding for the collection
of any principal and income arising from, or institute, appear in or defend any proceeding of any kind with respect to, any of the Property
unless and until it shall have received instructions from the Company given as provided herein to do so and the Company shall have advanced
or guaranteed to it funds sufficient to pay any expenses incident thereto;


 


(d) Refund any depreciation in principal of any
Property;


 


(e) Assume that the authority of any person designated
by the Company to give instructions hereunder shall not be continuing unless provided otherwise in such designation, or unless the Company
shall have delivered a written revocation of such authority to the Trustee;


 


(f) The other parties hereto or to anyone else
for any action taken or omitted by it, or any action suffered by it to be taken or omitted, in good faith and in the Trustee’s best
judgment, except for the Trustee’s gross negligence, fraud or willful misconduct. The Trustee may rely conclusively and shall be
protected in acting upon any order, notice, demand, certificate, opinion or advice of counsel (including counsel chosen by the Trustee,
which counsel may be the Company’s counsel), statement, instrument, report or other paper or document (not only as to its due execution
and the validity and effectiveness of its provisions, but also as to the truth and acceptability of any information therein contained)
which the Trustee believes, in good faith and with reasonable care, to be genuine and to be signed or presented by the proper person or
persons. The Trustee shall not be bound by any notice or demand, or any waiver, modification, termination or rescission of this Agreement
or any of the terms hereof, unless evidenced by a written instrument delivered to the Trustee, signed by the proper party or parties and,
if the duties or rights of the Trustee are affected, unless it shall give its prior written consent thereto;


 


(g) Verify the accuracy of the information contained
in the Registration Statement;


 


(h) Provide any assurance that any Business Combination
entered into by the Company or any other action taken by the Company is as contemplated by the Registration Statement;

the taxes payable by the Company, if any, relating to any interest income earned on the Property;


 


(j) Prepare, execute and file tax reports, income
or other tax returns and pay any taxes with respect to any income generated by, and activities relating to, the Trust Account, regardless
of whether such tax is payable by the Trust Account or the Company, including, but not limited to, franchise and income tax obligations,
except pursuant to Section 1(j) hereof; or


 






    4


     


    

 


(k) Verify calculations, qualify or otherwise
approve the Company’s written requests for distributions pursuant to Sections 1(i), 1(j) or 1(k) hereof.


 


4. Trust Account Waiver. The Trustee
has no right of set-off or any right, title, interest or claim of any kind (“Claim”) to, or to any monies in,
the Trust Account, and hereby irrevocably waives any Claim to, or to any monies in, the Trust Account that it may have now or in the future.
In the event the Trustee has any Claim against the Company under this Agreement, including, without limitation, under Section
2(b) or Section 2(c) hereof, the Trustee shall pursue such Claim solely against the Company and its assets outside
the Trust Account and not against the Property or any monies in the Trust Account.


 


5. Termination. This Agreement shall
terminate as follows:


 


(a) If the Trustee gives written notice to the
Company that it desires to resign under this Agreement, the Company shall use its reasonable efforts to locate a successor trustee, pending
which the Trustee shall continue to act in accordance with this Agreement. At such time that the Company notifies the Trustee that a successor
trustee has been appointed and has agreed to become subject to the terms of this Agreement, the Trustee shall transfer the management
of the Trust Account to the successor trustee, including but not limited to the transfer of copies of the reports and statements relating
to the Trust Account, whereupon this Agreement shall terminate; provided, however, that in the event that the
Company does not locate a successor trustee within ninety (90) days of receipt of the resignation notice from the Trustee, the Trustee
may submit an application to have the Property deposited with any court in the State of New York or with the United States District Court
for the Southern District of New York and upon such deposit, the Trustee shall be immune from any liability whatsoever; or


 


(b) At such time that the Trustee has completed
the liquidation of the Trust Account and its obligations in accordance with the provisions of Section 1(i) hereof (which
section may not be amended under any circumstances) and distributed the Property in accordance with the provisions of the Termination
Letter, this Agreement shall terminate except with respect to Section 2(b).


 


6. Miscellaneous.


 


(a) The Company and the Trustee each acknowledge
that the Trustee will follow the security procedures set forth below with respect to funds transferred from the Trust Account. The Company
and the Trustee will each restrict access to confidential information relating to such security procedures to authorized persons. Each
party must notify the other party immediately if it has reason to believe unauthorized persons may have obtained access to such confidential
information, or of any change in its authorized personnel. In executing funds transfers, the Trustee shall rely upon all information supplied
to it by the Company, including, account names, account numbers, and all other identifying information relating to a Beneficiary, Beneficiary’s
bank or intermediary bank. Except for any liability arising out of the Trustee’s gross negligence, fraud or willful misconduct,
the Trustee shall not be liable for any loss, liability or expense resulting from any error in the information or transmission of the
funds.


 


(b) This Agreement shall be governed by and construed
and enforced in accordance with the laws of the State of New York, without giving effect to conflicts of law principles that would result
in the application of the substantive laws of another jurisdiction. This Agreement may be executed in several original or facsimile counterparts,
each one of which shall constitute an original, and together shall constitute but one instrument.


 


(c) This Agreement contains the entire agreement
and understanding of the parties hereto with respect to the subject matter hereof. This Agreement or any provision hereof may only be
changed, amended or modified (other than to correct a typographical error) by a writing signed by each of the parties hereto; provided,
however, that no such change, amendment or modification to Section 1(i), 2(f) or Exhibit A may be made without the prior written
consent of the Representative.


 






    5


     


    

 


(d) This Agreement or any provision hereof may
only be changed, amended or modified pursuant to Section 6(c) hereof with the Consent of the Stockholders. For purposes
of this Section 6(d), the “Consent of the Stockholders”
means receipt by the Trustee of a certificate from the inspector of elections of the stockholder meeting certifying that the Company’s
stockholders of record as of a record date established in accordance with Section 213(a) of the Delaware General Corporation Law, as amended
(“DGCL”) (or any successor rule), who hold sixty-five percent (65%) or more of all then outstanding shares of
Common Stock and Class B common stock, par value $0.0001 per share, of the Company voting together as a single class, have voted in favor
of such change, amendment or modification. No such amendment will affect any Public Stockholder who has otherwise indicated his election
to redeem his shares of Common Stock in connection with a stockholder vote sought to amend this Agreement to modify the substance or timing
of the Company’s obligation to allow redemption in connection with its initial Business Combination or to redeem one hundred percent
(100%) of the public shares of Common Stock if the Company does not complete its initial Business Combination within the time frame specified
in the Company’s amended and restated certificate of incorporation, or with respect to any other provision relating to stockholders’
rights or pre-initial Business Combination activity. Except for any liability arising out of the Trustee’s gross negligence, fraud
or willful misconduct, the Trustee may rely conclusively on the certification from the inspector or elections referenced above and shall
be relieved of all liability to any party for executing the proposed amendment in reliance thereon.


 


(e) The parties hereto consent to the jurisdiction
and venue of any state or federal court located in the City of New York, State of New York, for purposes of resolving any disputes hereunder.
AS TO ANY CLAIM, CROSS-CLAIM OR COUNTERCLAIM IN ANY WAY RELATING TO THIS AGREEMENT, EACH PARTY WAIVES THE RIGHT TO TRIAL BY JURY.


 


(f) Any notice, consent or request to be given
in connection with any of the terms or provisions of this Agreement shall be in writing and shall be sent by express mail or similar private

	 	Re:	Trust Account Termination Letter


 


Dear Mr. Wolf and Ms. Gonzalez:


 


Pursuant to Section 1(i) of the Investment Management
Trust Agreement between Thunder Bridge Capital Partners IV Inc. (the “Company”) and Continental Stock Transfer
& Trust Company (the “Trustee”), dated as of ___, 2021 (the “Trust Agreement”),
this is to advise you that the Company has entered into an agreement with (the “Target Business”) to consummate
a business combination with the Target Business (the “Business Combination”) on or about
[insert date]. The Company shall notify you at least seventy-two (72) hours (or such shorter time as you may agree) in advance of the
actual date of the consummation of the Business Combination (the “Consummation Date”). Capitalized
terms used but not defined herein shall have the meanings set forth in the Trust Agreement.


 


In accordance with the terms of the Trust Agreement,
we hereby authorize you to commence to liquidate all of the assets of the Trust Account and 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 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 their respective portions
of the Deferred Discount)). It is acknowledged and agreed that while the funds are on deposit in the trust operating account at J.P. Morgan
Chase Bank, N.A. awaiting distribution, the Company will not earn any interest or dividends.


 


On the Consummation Date, (i) counsel for the Company
shall deliver to you written notification that the Business Combination has been consummated, or will be consummated concurrently with
your transfer of funds to the accounts as directed by the Company (the “Notification”) and (ii) the Company
shall deliver to you (a) a certificate of the Chief Executive Officer, which verifies that the Business Combination has been approved
by a vote of the Company’s stockholders, if a vote is held and (b) a joint written instruction signed by the Company and the Representative
with respect to the transfer of the funds held in the Trust Account, including payment of amounts owed to public stockholders who have
properly exercised their redemption rights and payment of the Deferred Discount to the Representative from the Trust Account (the “Instruction Letter”).
You are hereby directed and authorized to transfer the funds held in the Trust Account immediately upon your receipt of the Notification
and the Instruction Letter, in accordance with the terms of the Instruction Letter. In the event that certain deposits held in the Trust
Account may not be liquidated by the Consummation Date without penalty, you will notify the Company in writing of the same and the Company
shall direct you as to whether such funds should remain in the Trust Account and be distributed after the Consummation Date to the Company.
Upon the distribution of all the funds, net of any payments necessary for reasonable unreimbursed expenses related to liquidating the
Trust Account, your obligations under the Trust Agreement shall be terminated.


 


In the event that the Business Combination is
not consummated on the Consummation Date described in the notice thereof and we have not notified you on or before the original Consummation
Date of a new Consummation Date, then upon receipt by the Trustee of written instructions from the Company, the funds held in the Trust
Account shall be reinvested as provided in Section 1(c) of the Trust Agreement on the business day immediately following the Consummation
Date as set forth in such notice as soon thereafter as possible.


 


	 	Very truly yours,

Dear Mr. Wolf and Ms. Gonzalez:


 


Pursuant to Section 1(i) of the Investment Management
Trust Agreement between Thunder Bridge Capital Partners IV Inc. (the “Company”) and Continental Stock Transfer
& Trust Company (the “Trustee”), dated as of ___, 2021 (the “Trust Agreement”),
this is to advise you that the Company has been unable to effect a business combination with a target business (the “Business Combination”)
within the time frame specified in Section 1(i) of the Trust Agreement. Capitalized terms used but not defined herein shall have the meanings
set forth in the Trust Agreement.


 


In accordance with the terms of the Trust Agreement,
we hereby authorize you to liquidate all of the assets in the Trust Account and to transfer the total proceeds into a segregated account
held by you on behalf of the Beneficiaries to await distribution to the Public Stockholders. The Company has selected (1) as
the effective date for the purpose of determining when the Public Stockholders will be entitled to receive their share of the liquidation
proceeds. You agree to be the Paying Agent of record and, in your separate capacity as Paying Agent, agree to distribute said funds directly
to the Company’s Public Stockholders in accordance with the terms of the Trust Agreement and the Amended and Restated Certificate
of Incorporation of the Company. Upon the distribution of all the funds, net of any payments necessary for reasonable unreimbursed expenses
