Re:Initial Public Offering

 

Ladies and Gentlemen:

 

This letter (this “Letter Agreement”)
is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”) to be entered
into by and among Hennessy Capital Investment Corp. VI, a Delaware corporation (the “Company”) and Citigroup Global
Markets Inc. and Barclays Capital Inc. (collectively, the “Representatives”), relating to an underwritten initial public
offering (the “Public Offering”), of 34,500,000 of the Company’s units (including up to 4,500,000 units that
may be purchased to cover over-allotments, if any) (the “Units”), each comprised of one share of the Company’s
Class A common stock, par value $0.0001 per share (the “Common Stock”), and one-third of one redeemable warrant. Each
whole Warrant (each, a “Warrant”) entitles the holder thereof to purchase one share of Common Stock at a price of $11.50
per share, subject to adjustment. The Units will be sold in the Public Offering pursuant to a registration statement on Form S-1, as amended,
and prospectus (the “Prospectus”) filed by the Company with the U.S. Securities and Exchange Commission (the “Commission”)
and the Company has applied to have the Units listed on the Nasdaq Global Market. Certain capitalized terms used herein are defined in
paragraph 11 hereof.

 

In order to induce the Company and the Representatives
to enter into the Underwriting Agreement and to proceed with the Public Offering and for other good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, Hennessy Capital Partners VI LLC (the “Sponsor”) and each of the
undersigned individuals, each of whom is a member of the Company’s board of directors and/or management team (each, an “Insider”
and collectively, the “Insiders”), hereby severally (and not jointly and severally) agrees with the Company as follows:

 

1. The
Sponsor and each Insider agrees that if the Company seeks stockholder approval of a proposed Business Combination, then in connection
with such proposed Business Combination, it, he or she shall (i) vote any shares of Capital Stock owned by it, him or her in favor of
any proposed Business Combination and (ii) not redeem any shares of Common Stock owned by it, him or her in connection with such stockholder
approval. If the Company seeks to consummate a proposed Business Combination by engaging in a tender offer, the Sponsor and each Insider
agrees that it, he or she will not sell or tender any shares of Capital Stock owned by it, him or her in connection therewith.

 

2. The Sponsor and each Insider hereby agrees that
in the event that the Company fails to consummate a Business Combination within 24 months from the closing of the Public Offering or
such later period approved by the Company’s stockholders in accordance with the Company’s amended and restated certificate
of incorporation (the “Charter”), the Sponsor and each Insider shall take all reasonable steps to cause the Company
to (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than 10 business
days thereafter, subject to lawfully available funds therefor, redeem 100% of the Common Stock sold as part of the Units in the Public
Offering (the “Offering Shares”), at a per-share price, payable in cash, equal to the aggregate amount then on deposit
in the Trust Account, including interest (net of amounts withdrawn to pay the Company’s taxes (“Permitted Withdrawals”))
and less up to $100,000 of interest to pay dissolution expenses)), divided by the number of then outstanding Offering Shares, which redemption
will completely extinguish all Public Stockholders’ rights as stockholders (including the right to receive further liquidating
distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to
the approval of the Company’s remaining stockholders and the Company’s board of directors, dissolve and liquidate, subject
in each case to the Company’s obligations under Delaware law to provide for claims of creditors and other requirements of applicable
law. The Sponsor and each Insider agree to not propose any amendment to the Charter that would modify the substance or timing of the
Company’s obligation to redeem 100% of the Offering Shares if the Company does not complete a Business Combination within the required
time period set forth in the Charter or with respect to any other material provisions relating to stockholders’ rights or pre-initial
business combination activity, unless the Company provides its Public Stockholders with the opportunity to redeem their Offering Shares
upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust
Account, including interest (net of Permitted Withdrawals), divided by the number of then outstanding Offering Shares.

 

     

     

    

 

The Sponsor and each Insider acknowledges
that it, he or she has no right, title, interest or claim of any kind in or to any monies held in the Trust Account as a result of any
liquidation of the Company with respect to the Founder Shares held by it, him or her. The Sponsor and each Insider hereby further waive,
with respect to any shares of Common Stock held by it, him or her, if any, any redemption rights it, he or she may have in connection
with the consummation of a Business Combination, including, without limitation, any such rights available in the context of a stockholder
vote to approve such Business Combination or in the context of a tender offer made by the Company to purchase shares of Common Stock (although
the Sponsor, the Insiders and their respective affiliates shall be entitled to redemption and liquidation rights with respect to any Offering
Shares it or they hold if the Company fails to consummate a Business Combination within the time period set forth in the Charter or in
connection with a stockholder vote to approve an amendment to the Charter to modify the substance or timing of the Company’s obligation
to redeem 100% of the Offering Shares if the Company does not complete a Business Combination within the time period set forth in the
Charter or with respect to any other material provisions relating to stockholders’ rights or pre-initial business combination activity).

 

3. During
the period commencing on the effective date of the Underwriting Agreement and ending 180 days after such date, the Sponsor and each Insider
shall not, without the prior written consent of the Representatives, (i) sell, offer to sell, contract or agree to sell, hypothecate,
pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, or establish or increase
a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Securities Exchange
Act of 1934, as amended (the “Exchange Act”), and the rules and regulations of the Commission promulgated thereunder,
with respect to any Units, shares of Capital Stock, Warrants or any securities convertible into, or exercisable, or exchangeable for,
shares of Common Stock owned by it, him or her, (ii) enter into any swap or other arrangement that transfers to another, in whole or in
part, any of the economic consequences of ownership of any Units, shares of Capital Stock, Warrants or any securities convertible into,
or exercisable, or exchangeable for, shares of Common Stock owned by it, him or her, whether any such transaction is to be settled by
delivery of such securities, in cash or otherwise, or

(iii) publicly announce any intention to effect any transaction
specified in clause (i) or (ii).

 

4. In the event of the liquidation of the Trust
Account, the Sponsor (which for purposes of clarification shall not extend to any other shareholders, members or managers of the
Sponsor or any other Insider) agrees to indemnify and hold harmless the Company against any and all loss, liability, claim, damage
and expense whatsoever (including, but not limited to, any and all legal or other expenses reasonably incurred in investigating,
preparing or defending against any litigation, whether pending or threatened, or any claim whatsoever) to which the Company may
become subject as a result of any claim by (i) any third party for services rendered or products sold to the Company or (ii) any
prospective target business with which the Company has entered into a letter of intent, confidentiality or other similar agreement
for a Business Combination (a “Target”); provided, however, that such indemnification of the
Company by the Sponsor (x) shall apply only to the extent necessary to ensure that such claims by a third party or a Target do not
reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00 per Offering Share or (ii) the actual amount per
Offering Share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.00 per Offering
Share is then held in the Trust Account due to reductions in the value of the trust assets less Permitted Withdrawals, (y) shall not
apply to any claims by a third party (including a Target) that executed a waiver of any and all rights to the monies held in the
Trust Account (whether or not such waiver is enforceable) and (z) shall not apply to any claims under the Company’s indemnity
of the Representatives against certain liabilities, including liabilities under the Securities Act of 1933, as amended. The Sponsor
shall have the right to defend against any such claim with counsel of its choice reasonably satisfactory to the Company if, within
15 days following written receipt of notice of the claim to the Sponsor, the Sponsor notifies the Company in writing that it shall
undertake such defense. For the avoidance of doubt, none of the Company’s officers or directors will indemnify the Company for
claims by third parties, including, without limitation, claims by vendors and prospective target businesses.

5. To
the extent that the Representatives do not exercise their over-allotment option to purchase up to an additional 4,500,000 Units within
45 days from the date of the Prospectus (and as further described in the Prospectus), the Sponsor agrees to forfeit, at no cost, a number
of Founder Shares in the aggregate equal to the product of 1,500,000 multiplied by a fraction, (i) the numerator of which is 4,500,000
minus the number of Units purchased by the Representatives upon the exercise of its over-allotment option, and (ii) the denominator of
which is 4,500,000. The forfeiture will be adjusted to the extent that the over-allotment option is not exercised in full by the Representatives
so that the Initial Stockholders will own an aggregate of 25.0% of the Company’s issued and outstanding shares of Capital Stock
after the Public Offering. To the extent that the size of the Public Offering is increased or decreased, the Company will effect a capitalization
or share repurchase, redemption or stock split or other appropriate mechanism, as applicable, immediately prior to the consummation of
the Public Offering in such amount as to maintain the ownership of the Capital Stock of the Initial Stockholders prior to the Public Offering
at 25.0% of the Company’s issued and outstanding Capital Stock upon the consummation of the Public Offering. In connection with
such increase or decrease in the size of the Public Offering, (A) references to 4,500,000 in the numerator and denominator of the formula
in the first sentence of this paragraph shall be changed to a number equal to 15% of the number of shares included in the Units issued
in the Public Offering and (B) the reference to 1,500,000 in the formula set forth in the immediately preceding sentence shall be adjusted
to such number of Founder Shares that the Sponsor would have to return to the Company in order to hold (with all of the Initial Stockholders)
an aggregate of 25.0% of the Company’s issued and outstanding Capital Stock after the Public Offering.

 

6. (a)
The Sponsor and each Insider hereby agrees and acknowledges that: (i) the Representatives and the Company would be irreparably injured
in the event of a breach by such Sponsor or an Insider of its, his or her obligations under paragraphs 1, 2, 3, 4, 5, 7(a), 7(b), and
9, as applicable, of this Letter Agreement (ii) monetary damages may not be an adequate remedy for such breach and (iii) the non- breaching
party shall be entitled to injunctive relief, in addition to any other remedy that such party may have in law or in equity, in the event
of such breach.

 

7. (a)
The Sponsor and each Insider agrees that it, he or she shall not Transfer any Founder Shares (or shares of Common Stock issuable upon
conversion thereof) until the earlier of (A) one year after the completion of the Company’s initial Business Combination or (B)
subsequent to the Business Combination,

(x) if the last
reported sale price of the Common Stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations,
recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the Company’s
initial Business Combination or (y) the date on which the Company completes a liquidation, merger, capital stock exchange, reorganization
or other similar transaction that results in all of the Company’s stockholders having the right to exchange their shares of Common
Stock for cash, securities or other property (the “Founder Shares

Lock-up Period”).

 

(b) The
Sponsor and each Insider agree that it, he or she shall not Transfer any Private Placement Warrants (or shares of Common Stock issued
or issuable upon the exercise of the Private Placement Warrants) until 30 days after the completion of a Business Combination (the “Private
Placement Warrants Lock-up Period”, together with the Founder Shares Lock-up Period, the “Lock-up Periods”).

 

(c) Notwithstanding the provisions set forth in
paragraphs 3 and 7(a) and (b), Transfers of the Founder Shares, Private Placement Warrants and shares of Common Stock issued or
issuable upon the exercise or conversion of the Private Placement Warrants or the Founder Shares and that are held by the Sponsor,
any Insider or any of their permitted transferees (that have complied with this paragraph 7(c)), are permitted (a) to the
Company’s officers or directors, any affiliates or family members of any of the Company’s officers or directors, any
members of the Sponsor, or any affiliates of the Sponsor; (b) in the case of an individual, transfers by gift to a member of the
individual’s immediate family, to a trust, the beneficiary of which is a member of the individual’s immediate family or
an affiliate of such person, or to a charitable organization; (c) in the case of an individual, transfers by virtue of laws of
descent and distribution upon death of the individual; (d) in the case of an individual, transfers pursuant to a qualified domestic
relations order; (e) transfers by private sales or transfers made in connection with the consummation of a Business Combination at
prices no greater than the price at which the securities were originally purchased; (f) transfers in the event of the
Company’s liquidation prior to the completion of an initial Business Combination; (g) transfers by virtue of the laws of the
State of Delaware or the Sponsor’s limited liability company agreement upon dissolution of the Sponsor; (h) in the event of
the Company’s completion of a liquidation, merger, stock exchange, reorganization or other similar transaction which results
in all of the Company’s public stockholders having the right to exchange their shares of Class A common stock for cash,
securities or other property subsequent to the completion of the initial business combination; (i) to a nominee or custodian of a
person or entity to whom a disposition or transfer would be permissible under clauses (a) through (h) above; provided, however,
that in the case of clauses (a) through (e) and (i), these permitted transferees must enter into a written agreement with the
Company agreeing to be bound by the transfer restrictions herein and the other restrictions contained in this Agreement (including
provisions relating to voting, the Trust Account and liquidating distributions).

 

    3

     

    

 

8. The
Sponsor and each Insider represent and warrant that it, he or she has never been suspended or expelled from membership in any securities
or commodities exchange or association or had a securities or commodities license or registration denied, suspended or revoked. Each Insider’s
biographical information furnished to the Company (including any such information included in the Prospectus) is true and accurate in
all respects and does not omit any material information with respect to the Insider’s background. The Sponsor and each Insider’s
questionnaire furnished to the Company is true and accurate in all respects. The Sponsor and each Insider represents and warrants that:
it, he or she is not subject to or a respondent in any legal action for, any injunction, cease-and-desist order or order or stipulation
to desist or refrain from any act or practice relating to the offering of securities in any jurisdiction; it, he or she has never been
convicted of, or pleaded guilty to, any crime (i) involving fraud, (ii) relating to any financial transaction or handling of funds of
another person, or (iii) pertaining to any dealings in any securities and it, he or she is not currently a defendant in any such criminal
proceeding.

 

9. Except
as disclosed in the Prospectus, neither the Sponsor nor any Insider nor any affiliate of the Sponsor or any Insider, nor any director
or officer of the Company, shall receive from the Company any finder’s fee, reimbursement, consulting fee, monies in respect of
any repayment of a loan or other compensation prior to, or in connection with any services rendered in order to effectuate the consummation
of the Company’s initial Business Combination (regardless of the type of transaction that it is), other than the following, none
of which will be made from the proceeds held in the Trust Account prior to the completion of the initial Business Combination: repayment
of a loan and advances of up to $500,000 made to the Company by the Sponsor to cover expenses related to the organization of the Company
and the Public Offering; payment to an affiliate of the Sponsor for certain office space, utilities and secretarial and administrative
support as may be reasonably required by the Company for a total of $15,000 per month, payments to each of our President and Chief Operating
Officer and our Chief Financial Officer of $29,000 per month for their services until the completion of our initial business combination,
of which $14,000 per month is payable upon the completion of our initial business combination; reimbursement for any reasonable out-of-pocket
expenses related to identifying, investigating and consummating an initial Business Combination, and repayment of loans, if any, and on
such terms as to be determined by the Company from time to time, made by the Sponsor or certain of the Company’s officers and directors
to finance transaction costs in connection with an intended initial Business Combination, provided, that, if the Company does not consummate
an initial Business Combination, a portion of the working capital held outside the Trust Account may be used by the Company to repay such
loaned amounts so long as no proceeds from the Trust Account are used for such repayment. Up to $1,500,000 of such loans may be convertible
into warrants of the post Business Combination entity at a price of $1.50 per warrant at the option of the lender. Such warrants would
be identical to the Private Placement Warrants, including as to exercise price, exercisability and exercise period.

 

10. The Sponsor and each Insider has full right
and power, without violating any agreement to which it is bound (including, without limitation, any non-competition or
non-solicitation agreement with any employer or former employer), to enter into this Letter Agreement and, as applicable, to serve
as an officer and/or a director on the board of directors of the Company and hereby consents to being named in the Prospectus as an
officer and/or a director of the Company.

13. Except
as otherwise provided herein, no party hereto may assign either this Letter Agreement or any of its rights, interests, or obligations

Letter 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. The parties
hereto (i) all agree that any action, proceeding, claim or dispute arising out of, or relating in any way to, this Letter Agreement shall
be brought and enforced in the courts of New York City, in the State of New York, and irrevocably submit to such jurisdiction and venue,
which jurisdiction and venue shall be exclusive and (ii) waive any objection to such exclusive jurisdiction and venue or that such courts
represent an inconvenient forum.

 

18. Any
notice, consent or request to be given in connection with any of the terms or provisions of this Letter Agreement shall be in writing

share (the “Common Stock”), and one-third of one redeemable warrant, each whole warrant entitling the holder
thereof to purchase one share of Common Stock (such initial public offering hereinafter referred to as the

and

 

WHEREAS,
the Company has entered into an Underwriting Agreement (the “Underwriting Agreement”) with Citigroup Global Markets

NOW
THEREFORE, IT IS AGREED:

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

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

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

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

consummation of the Offering. 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 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;

 

    3

    

    

 

(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
$10,500,000 or

the investment of any Property, other than in compliance with Section 1 hereof, and in no event shall the Trustee be liable for

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

execute and file tax reports, income or other tax returns and pay any taxes with respect to any income generated by, and activities relating

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

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 and Replacement of Trustee. 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

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 and any other reasonable transfer requests that the Company may make, 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 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,
or its representatives’, 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.

 

    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.

 

(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

		Re:	Trust
Account 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) 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
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 written instruction as soon thereafter as possible.
