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
(the “Class A Common Stock”), of Integrated Energy Transition Acquisition Corp., 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 (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 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 Common Stock to be issued to the Warrant 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.


 


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 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
shares of Class A Common Stock and are issued or to be issued pursuant to a Warrant Agreement dated as of March [•], 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 issuance of 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 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 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.

(To Be Executed Upon Exercise
of Warrant)


 


 


The

Class A Common Stock is less than all of the shares of Class A Common Stock purchasable hereunder, the undersigned requests
that a new Warrant Certificate representing the remaining balance of such shares of Class A Common Stock be registered in the
name of           , whose address
is              and that such Warrant
Certificate be delivered to               ,
whose address is               .


 


In the
event that the Warrant has been called for redemption by the Company pursuant to Section 6.2 of the Warrant Agreement and

that this Warrant is exercisable for shall be determined in accordance with subsection 3.3.1(c) or Section 6.2 of
the Warrant Agreement, as applicable.


 


In the
event that the Warrant is a Private Placement Warrant or a Working Capital Warrant that is to be exercised on a “cashless
basis” pursuant to subsection 3.3.1(c) of the Warrant Agreement, the number of shares of Class A Common Stock that
this Warrant is exercisable for shall be determined in accordance with subsection 3.3.1(c) of the Warrant Agreement.


 


In the
event that the Warrant is to be exercised on a “cashless basis” pursuant to Section 7.4 of the Warrant Agreement,
the number of shares of Class A Common Stock that this Warrant is exercisable for shall be determined in accordance with Section
7.4 of the Warrant Agreement.


 


In the
event that the Warrant may be exercised, to the extent allowed by the Warrant Agreement, through cashless exercise (i) the number
of shares of Class A Common Stock that this Warrant is exercisable for would be determined in accordance with the relevant section
of the Warrant Agreement which allows for such cashless exercise and (ii) the holder hereof shall complete the following: The undersigned
hereby irrevocably elects to exercise the right, represented by this Warrant Certificate, through the cashless exercise provisions
of the Warrant Agreement, to receive shares of Class A Common Stock. If said number of shares is less than all of the shares of
Class A Common Stock purchasable hereunder (after giving effect to the cashless exercise), the undersigned requests that a new
Warrant Certificate representing the remaining balance of such shares of Common Stock be registered in the name of


          , whose address is                  and
that such Warrant Certificate be delivered to


                 , whose address is                 .
