Warrant Certificate

 

This Warrant Certificate certifies that , or registered
assigns, is the registered holder of warrant(s) evidenced hereby (the “Warrants” and each, a “Warrant”)
to purchase shares of Class A common stock, $0.0001 par value per share (“Common Stock”), of Hennessy Capital
Investment Corp. V, a Delaware corporation (the “Company”). Each whole Warrant entitles the holder, upon exercise
during the period set forth in the Warrant Agreement referred to below, to receive from the Company that number of fully paid and
non-assessable shares of Common Stock as set forth below, at the exercise price (the “Warrant Price”) as determined
pursuant to the Warrant Agreement, payable in lawful money (or through “cashless exercise” as provided for in the Warrant
Agreement) of the United States of America upon surrender of this Warrant Certificate and payment of the Warrant Price at the office
or agency of the Warrant Agent referred to below, subject to the conditions set forth herein and in the Warrant Agreement. Defined
terms used in this Warrant Certificate but not defined herein shall have the meanings given to them in the Warrant Agreement.

 

Each whole Warrant is initially exercisable for one fully paid
and non-assessable share of Common Stock. No fractional shares will be issued upon exercise of any Warrant. If, upon the exercise
of Warrants, a holder would be entitled to receive a fractional interest in a share of Common Stock, the Company will, upon exercise,
round down to the nearest whole number of the number of shares of Common Stock to be issued to the holder. The number of shares
of Common Stock issuable upon exercise of the Warrants is subject to adjustment upon the occurrence of certain events as set forth
in the Warrant Agreement.

 

     

     

    

 

[Form of Warrant]

 

The initial Warrant Price per share of Common Stock for any
Warrant is equal to $11.50 per share. The Warrant Price is subject to adjustment upon the occurrence of certain events as set forth
in the Warrant Agreement.

 

Subject to the conditions set forth in the Warrant Agreement,
the Warrants may be exercised only during the Exercise Period and to the extent not exercised by the end of such Exercise Period,
such Warrants shall become null and void. The Warrants may be redeemed, subject to certain conditions, as set forth in the Warrant
Agreement.

 

Reference is hereby made to the further provisions of this Warrant
Certificate set forth on the reverse hereof and such further provisions shall for all purposes have the same effect as though fully
set forth at this place.

 

This Warrant Certificate shall not be valid unless countersigned
by the Warrant Agent, as such term is used in the Warrant Agreement.

 

This Warrant Certificate shall be governed by and construed
in accordance with the internal laws of the State of New York.

The Warrants evidenced by this Warrant Certificate are part
of a duly authorized issue of Warrants entitling the holder on exercise to receive shares of Common Stock and are issued or to
be issued pursuant to a Warrant Agreement dated as of      , 2021 (the “Warrant Agreement”),
duly executed and delivered by the Company to Continental Stock Transfer & Trust Company, a New York corporation, as warrant
agent (or successor warrant agent) (collectively, the “Warrant Agent”), which Warrant Agreement is hereby incorporated
by reference in and made a part of this instrument and is hereby referred to for a description of the rights, limitation of rights,
obligations, duties and immunities thereunder of the Warrant Agent, the Company and the holders (the words “holders”
or “holder” meaning the Registered Holders or Registered Holder, respectively) of the Warrants. A copy of the
Warrant Agreement may be obtained by the holder hereof upon written request to the Company. Defined terms used in this Warrant
Certificate but not defined herein shall have the meanings given to them in the Warrant Agreement.

 

Warrants may be exercised at any time during the Exercise Period
set forth in the Warrant Agreement. The holder of Warrants evidenced by this Warrant Certificate may exercise them by surrendering
this Warrant Certificate, with the form of election to purchase set forth hereon properly completed and executed, together with
payment of the Warrant Price as specified in the Warrant Agreement (or through “cashless exercise” as provided for
in the Warrant Agreement) at the designated office of the Warrant Agent. In the event that upon any exercise of Warrants evidenced
hereby the number of Warrants exercised shall be less than the total number of Warrants evidenced hereby, there shall be issued
to the holder hereof or his, her or its assignee, a new Warrant Certificate evidencing the number of Warrants not exercised.

 

Notwithstanding anything else in this Warrant Certificate or
the Warrant Agreement, no Warrant may be exercised unless at the time of exercise (i) a registration statement covering the shares
of Common Stock to be issued upon exercise is effective under the Securities Act and (ii) a prospectus thereunder relating to the
shares of Common Stock is current, except through “cashless exercise” as provided for in the Warrant Agreement.

 

The Warrant Agreement provides that upon the occurrence of certain
events the number of shares of Common Stock issuable upon exercise of the Warrants set forth on the face hereof may, subject to
certain conditions, be adjusted. If, upon exercise of a Warrant, the holder thereof would be entitled to receive a fractional interest
in a share of Common Stock, the Company shall, upon exercise, round down to the nearest whole number of shares of Common Stock
to be issued to the holder of the Warrant.

 

Warrant Certificates, when surrendered at the designated office
of the Warrant Agent by the Registered Holder thereof in person or by legal representative or attorney duly authorized in writing,
may be exchanged, in the manner and subject to the limitations provided in the Warrant Agreement, but without payment of any service
charge, for another Warrant Certificate or Warrant Certificates of like tenor evidencing in the aggregate a like number of Warrants.

 

Upon due presentation for registration of transfer of this Warrant
Certificate at the office of the Warrant Agent a new Warrant Certificate or Warrant Certificates of like tenor and evidencing in
the aggregate a like number of Warrants shall be issued to the transferee(s) in exchange for this Warrant Certificate, subject
to the limitations provided in the Warrant Agreement, without charge except for any tax or other third-party charges imposed in
connection therewith.

 

The Company and the Warrant Agent may deem and treat the Registered
Holder(s) hereof as the absolute owner(s) of this Warrant Certificate (notwithstanding any notation of ownership or other writing
hereon made by anyone), for the purpose of any exercise hereof, of any distribution to the holder(s) hereof, and for all other
purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary. Neither the Warrants nor
this Warrant Certificate entitles any holder hereof to any rights of a stockholder of the Company.
