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 Thunder Bridge Capital Partners IV Inc., 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.

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, without regard to conflicts of laws principles.

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.
