NOW
THEREFORE, IT IS AGREED:

Hold the Property in trust for the Beneficiaries in accordance with the terms of this Agreement in the Trust Account established

Company;


 


(b)
Manage, supervise and administer the Trust Account subject to the terms and conditions set forth herein;

Rule 2a-7 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 Trustee has no obligation
to monitor or question the Company’s determination that an investment is in compliance with the foregoing clause; the Company
shall not instruct the Trustee to invest in any other securities or assets, 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
credit 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)
As soon as practicable notify the Company and the Representatives 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

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 only after and promptly after (x) 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 its Chief Executive
Officer, President, Chief Financial Officer, 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 Exhibit A, acknowledged and agreed to by the Representatives
and complete the liquidation of the Trust Account and distribute the Property in the Trust Account, including interest earned
on funds held in the Trust Account (net of amounts withdrawn in accordance with this Agreement and less up to $100,000 of interest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) upon the date which is the later of (i) 24 months after the closing of the Offering
(or 27 months from the closing of the Offering, if the Company has executed a letter of intent, agreement in principle or definitive
agreement for its initial business combination within 24 months from the closing of the Offering but has not completed its initial
business combination within such 24-month period) and (ii) such later 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 and the Property in the Trust Account, including
interest earned on funds held in the Trust Account (net of amounts withdrawn in accordance with this Agreement and less up to
$100,000 of interest that may be released to the Company to pay dissolution expenses) shall be distributed to the Public Stockholders
of record as of such date;

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 such payment
the Company shall forward 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 relevant taxing authority for the Company. 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) [Reserved];

as is described in the Company’s amended and restated Certificate of Incorporation or with respect to any other material
provisions 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

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

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


 


(a)
Give all instructions to the Trustee hereunder in writing, signed by the Company’s Chairman of the Board, President,
Chief Executive Officer, Chief Financial Officer or Secretary. In addition, except with respect to its duties under Sections 1(i),
1(j), 1(k) and 1(l) hereof, the Trustee shall be entitled to rely on, and shall be protected in relying on, any
such written instructions and, further, 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 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, or
its representatives’, 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 shall not be unreasonably withheld, conditioned, or delayed; provided, further that the Company
may conduct and manage the defense against any Indemnified Claim if the Trustee does not promptly take reasonable steps to mount
such a defense. The Trustee may not agree to settle any Indemnified Claim without the prior written consent of the Company. The
Company may participate in any such action with its own counsel;


 


(c)
Pay the Trustee the fees set forth on Schedule A hereto, including an initial set-up 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 property is distributed to the Company pursuant
to Sections 1(i) hereof. The Company shall pay the Trustee the initial set-up 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;


 






    3


     


    




 


(e)
Provide the Representatives 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;


 


(f)
Unless otherwise agreed between the Company and the Representatives, ensure that any Instruction Letter delivered in connection
with a Termination Letter in the form of Exhibit A expressly provides that the Deferred Discount is paid
directly to the accounts as directed by the Representatives 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 Representatives 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, which
shall in no event be less than $7,000,000, or $8,050,000 if the underwriters’ overallotment option is exercised in full.

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, or its representatives’,
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

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, or its representatives’, gross negligence, fraud, or

    5


     


    




 


(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.


 


(d) Sections 1(i) and
1(l) hereof may only be changed, amended or modified pursuant to Section 6(c) hereof with the Consent
of the Stockholders, it being the specific intention of the parties hereto that each of the Company’s stockholders is, and
shall be, a third party beneficiary of this Section 6(d) with the same right and power to enforce this Section 6(d) as
the other parties hereto. 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 either
(i) 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 the 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, or (ii) the
Company’s stockholders of record as of the record date who hold sixty-five percent (65%) or more of all then outstanding
shares of the Common Stock and Class B common stock, par value $0.0001 per share, of the Company voting together as a single
class, have delivered to such entity a signed writing approving such change, amendment or modification. No such amendment will
affect any Public Stockholder who has otherwise indicated his election to redeem his share of Common Stock in connection with
a stockholder vote sought to amend the Certificate of Incorporation. Except for any liability arising out of the Trustee’s,
or its representatives’, 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, County
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.

	 	Re:	Trust Account No. Termination Letter


 


Ladies
and Gentlemen:


 


Pursuant
to Section 1(i) of the Investment Management Trust Agreement between Hennessy Capital Investment Corp.
VI (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 [insert name] (the “Target Business”) to consummate a business combination with Target Business
(the “Business Combination”) on or about [insert date]. The Company shall notify you at least seventy-two (72)
hours 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 to transfer the proceeds into the trust operating account at JPMorgan Chase Bank N.A. to the effect that, on the
Consummation Date, all of the funds held in the Trust Account 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 Representatives) (with respect to the
Deferred Discount). It is acknowledged and agreed that while the funds are on deposit in the trust operating account at JPMorgan
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) [an affidavit] [a certificate]
of the Chief Executive Officer of the Company, 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 Representatives
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 redemptions rights and payment of amounts of the Deferred Discount to the underwriter 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

In

of record and, in your separate capacity as Paying Agent, agree to distribute said funds directly to the 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 related to liquidating the
Trust Account, your obligations under the Trust Agreement shall be terminated, except to the extent otherwise provided in Section 1(i) of
the Trust Agreement.
