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 (“Class A Common Stock”), of Kimbell Tiger Acquisition Corporation,
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 Class A Common Stock as set forth below, at the exercise price (the “Warrant Price”) as determined pursuant
to the Warrant Agreement, payable in lawful money of the United States of America upon surrender of this Warrant Certificate and payment
of the Warrant Price (or through “cashless exercise” as provided for in the Warrant Agreement) at the office
or agency of the Warrant Agent referred to below, subject to the conditions set forth herein and in the Warrant Agreement. The Warrants
evidenced by this Warrant Certificate are [Public][Private Placement][Post-IPO] Warrants. Capitalized 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 Class A 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 Class A
Common Stock, the Company will, upon exercise, round down to the nearest whole number the number of shares of Class A Common Stock
to be issued to the Warrant holder. The number of shares of Class A Common Stock issuable upon exercise of the Warrants is subject
to adjustment upon the occurrence of certain events set forth in the Warrant Agreement.


 


The initial Warrant Price
per share of Class A 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 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.

[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 shares of Class A
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 (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 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 shares of Class A Common Stock to be issued upon exercise is effective under the Securities Act and (ii) a
prospectus thereunder relating to the shares of Class A Common Stock is current, except through “cashless exercise” as
provided for in the Warrant Agreement. In addition, and notwithstanding anything else in this Warrant Certificate or the Warrant Agreement,
to the extent that the holder of a Warrant has delivered a notice contemplated by subsection 3.5.5 of the Warrant Agreement, neither
the Company nor the Warrant Agent shall issue to Holder, and Holder may not acquire, any right it might have to acquire, a number of shares
of Common Stock upon exercise of any Warrant to the extent that, upon such exercise, the number of shares of Common Stock then beneficially
owned by Holder would exceed the Maximum Percentage of shares of Common Stock outstanding immediately after giving effect to such exercise
as determined in accordance with subsection 3.3.5 of the Warrant Agreement.


 


The Warrant Agreement provides
that upon the occurrence of certain events the number of shares of Class A 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 Class A Common Stock, the Company shall, upon exercise, round down to the
nearest whole number of shares of Class A Common Stock 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 stockholder of the Company.
