Thrive Acquisition Corporation


Incorporated Under the Laws of the Cayman Islands


 


Warrant Certificate


 


This Warrant Certificate
certifies that [             ], or registered assigns, is the
registered holder of [             ] warrant(s) (the “Warrants”
and each, a “Warrant”) to purchase Class A ordinary shares, $0.0001 par value (“Ordinary Shares”),
of Thrive Acquisition Corporation, a Cayman Islands exempted company (the “Company”). Each 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 nonassessable Ordinary Shares as set forth below, at the exercise price (the “Exercise 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 Exercise
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 Ordinary Share. Fractional shares shall not be issued upon exercise of any Warrant.
If, upon the exercise of Warrants, a holder would be entitled to receive a fractional interest in an Ordinary Share, the Company shall,
upon exercise, round down to the nearest whole number the number of Ordinary Shares to be issued to the Warrant holder. The number of
Ordinary Shares issuable upon exercise of the Warrants is subject to adjustment upon the occurrence of certain events as set forth in
the Warrant Agreement.


 


The initial Exercise Price
per one Ordinary Share for any Warrant is equal to $11.50 per share. The Exercise 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 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.

[Form of Warrant Certificate]



 


[Reverse]


 


The Warrants evidenced by
this Warrant Certificate are part of a duly authorized issue of Warrants entitling the holder on exercise to receive [             ]
Ordinary Shares 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 (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 Exercise Price as specified in the Warrant Agreement (or through “cashless exercise”
as provided for in the Warrant Agreement) at the principal corporate trust 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 issuance of the Ordinary Shares to be issued upon exercise is effective under the Securities Act and (ii) a prospectus thereunder
relating to the Ordinary Shares 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 Ordinary Shares 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 an Ordinary Share, the Company shall, upon exercise, round down to the nearest whole number of Ordinary Shares
to be issued to the holder of the Warrant.


 


Warrant Certificates, when
surrendered at the principal corporate trust 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 governmental charge
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 shareholder of the Company.

3.3.1(c) of the Warrant Agreement.


 


In the event that the Warrant

name of [             ], whose address is [             ]
