NOW THEREFORE, IT IS
AGREED:


 


1.                  
Agreements and Covenants of Trustee. The Trustee hereby agrees and covenants to:


 


(a)                
Hold the Property in trust for the Beneficiaries in accordance with the terms of this Agreement in the Trust Account established
by the Trustee in the United States at J.P. Morgan Chase Bank, N.A. (or at another U.S. chartered commercial bank with consolidated
assets of $100 billion or more) in the United States, maintained by the Trustee and at a brokerage institution selected by the
Trustee that is reasonably satisfactory to the Company;


 


(b)               
Manage, supervise and administer the Trust Account subject to the terms and conditions set forth herein;


 


(c)                
In a timely manner, upon the written instruction of the Company, invest and reinvest the Property solely in United States

of 185 days or less, or in money market funds meeting the conditions of paragraphs (d)(1), (d)(2), (d)(3) and (d)(4) of Rule 2a-7
promulgated under the Investment Company Act of 1940, as amended (or any successor rule), which invest only in direct U.S. government
treasury obligations, as determined by the Company; it being understood that the Trust Account will earn no interest while account
funds are uninvested awaiting the Company’s instructions hereunder and the Trustee may earn bank credits or other consideration;


 






     


     


    

 


(d)               
 Collect and receive, when due, all principal, interest or other income arising from the Property, which shall become part
of the “Property,” as such term is used herein;  


 


(e)                
Promptly notify the Company and the Representative of all communications received by the Trustee with respect to any Property
requiring action by the Company;


 


(f)                 
Supply any necessary information or documents as may be requested by the Company (or its authorized agents) in connection
with the Company’s preparation of the tax returns relating to assets held in the Trust Account;


 


(g)               
Participate in any plan or proceeding for protecting or enforcing any right or interest arising from the Property if, as
and when instructed by the Company to do so;


 


(h)               
Render to the Company monthly written statements of the activities of, and amounts in, the Trust Account reflecting all
receipts and disbursements of the Trust Account;


 


(i)                 
Commence liquidation of the Trust Account only after and promptly after (x) receipt of, and only in accordance with, the
terms of a letter from the Company (“Termination Letter”) in a form substantially similar to that attached
hereto as either Exhibit A or Exhibit B, as applicable, signed on behalf of the Company by its Chief Executive Officer,
Chief Financial Officer, Chief Operating Officer or Chairman of the board of directors of the Company (the “Board”)
or other authorized officer of the Company, and, in the case of Exhibit A, acknowledged and agreed to by the Representative,
and complete the liquidation of the Trust Account and distribute the Property in the Trust Account, including interest earned on
the funds held in the Trust Account and not previously released to the Company to pay its taxes (less up to $100,000 of interest
to pay dissolution expenses), only as directed in the Termination Letter and the other documents referred to therein, or (y) upon
the date which is, the later of (1) 24 months after the closing of the Offering and (2) such later date as may be approved by the
Company’s stockholders in accordance with the Company’s amended and restated certificate of incorporation if a Termination
Letter has not been received by the Trustee prior to such date, in which case the Trust Account shall be liquidated in accordance
with the procedures set forth in the Termination Letter attached as Exhibit B and the Property in the Trust Account, including
interest earned on the funds held in the Trust Account and not previously released to the Company to pay its taxes (less up to
$100,000 of interest to pay dissolution expenses), shall be distributed to the Public Stockholders of record as of such date;


 


(j)                 
Upon written request from the Company, which may be given from time to time in a form substantially similar to that attached
hereto as Exhibit C (a “Tax Payment Withdrawal Instruction”), withdraw from the Trust Account
and distribute to the Company the amount of interest earned on the Property requested by the Company to cover any tax obligation
owed by the Company as a result of assets of the Company or interest or other income earned on the Property, which amount shall
be delivered directly to the Company by electronic funds transfer or other method of prompt payment, and the Company shall forward
such payment to the relevant taxing authority, so long as there is no reduction in the principal amount per share initially deposited
in the Trust Account; provided, however, that to the extent there is not sufficient cash in the Trust Account to
pay such tax obligation, the Trustee shall liquidate such assets held in the Trust Account as shall be designated by the Company
in writing to make such distribution (it being acknowledged and agreed that any such amount in excess of interest income earned
on the Property shall not be payable from the Trust Account). The written request of the Company referenced above shall constitute
presumptive evidence that the Company is entitled to said funds, and the Trustee shall have no responsibility to look beyond said
request;


 


(k)                Upon
written request from the Company, which may be given from time to time in a form substantially similar to that attached
hereto as Exhibit D (a “Stockholder Redemption Withdrawal Instruction”), the Trustee shall
distribute on behalf of the Company the amount requested by the Company to be used to redeem shares of Common Stock from
Public Stockholders properly submitted in connection with a stockholder vote to approve an amendment to the Company’s
amended and restated certificate of incorporation to modify the substance or timing of the Company’s obligation to
allow redemption in connection with its Initial Business Combination or to redeem 100% of shares of Common Stock included in
the Units sold in the Offering (the “public shares”) if the Company has not consummated an initial
Business Combination within such time as is described in the Company’s amended and restated certificate of
incorporation or with respect to any other material provisions relating to stockholders’ rights or pre-initial Business
Combination activity. The written request of the Company referenced above shall constitute presumptive evidence that the
Company is entitled to distribute said funds, and the Trustee shall have no responsibility to look beyond said request;
and


 






    2 


     


    

 


(l)                 
Not make any withdrawals or distributions from the Trust Account other than pursuant to Section 1(i), (j)
or (k) above.


 


2.                  
Agreements and Covenants of the Company. The Company hereby agrees and covenants to:


 


(a)                
Give all instructions to the Trustee hereunder in writing, signed by the Company’s Chairman of the Board, Chief Executive
Officer, Chief Financial Officer or Chief Operating Officer. In addition, except with respect to its duties under Sections 1(i),
1(j) and 1(k) hereof, the Trustee shall be entitled to rely on, and shall be protected in relying on, any verbal
or telephonic advice or instruction which it, in good faith and with reasonable care, believes to be given by any one of the persons
authorized above to give written instructions, provided that the Company shall promptly confirm such instructions in writing;


 


(b)               
Subject to Section 4 hereof, hold the Trustee harmless and indemnify the Trustee from and against any and all expenses,
including reasonable counsel fees and disbursements, or losses suffered by the Trustee in connection with any action taken by it
hereunder and in connection with any action, suit or other proceeding brought against the Trustee involving any claim, or in connection
with any claim or demand, which in any way arises out of or relates to this Agreement, the services of the Trustee hereunder, or
the Property or any interest earned on the Property, except for expenses and losses resulting from the Trustee’s gross negligence,
fraud or willful misconduct. Promptly after the receipt by the Trustee of notice of demand or claim or the commencement of any
action, suit or proceeding, pursuant to which the Trustee intends to seek indemnification under this Section 2(b),
it shall notify the Company in writing of such claim (hereinafter referred to as the “Indemnified Claim”).
The Trustee shall have the right to conduct and manage the defense against such Indemnified Claim; provided that
the Trustee shall obtain the consent of the Company with respect to the selection of counsel, which consent shall not be unreasonably
withheld. The Trustee may not agree to settle any Indemnified Claim without the prior written consent of the Company, which such
consent shall not be unreasonably withheld. The Company may participate in such action with its own counsel;


 


(c)                
Pay the Trustee the fees set forth on Schedule A hereto, including an initial acceptance fee, annual administration
fee, and transaction processing fee which fees shall be subject to modification by the parties from time to time. It is expressly
understood that the Property shall not be used to pay such fees unless and until it is distributed to the Company pursuant to Sections
1(i) through 1(j) hereof. The Company shall pay the Trustee the initial acceptance fee and the first annual administration
fee at the consummation of the Offering. The Company shall not be responsible for any other fees or charges of the Trustee except
as set forth in this Section 2(c), Schedule A and as may be provided in Section 2(b) hereof;


 


(d)               
In connection with any vote of the Company’s stockholders regarding a merger, capital stock exchange, asset acquisition,
stock purchase, reorganization or similar business combination involving the Company and one or more businesses (the “Business
Combination”), provide to the Trustee an affidavit or certificate of the inspector of elections for the stockholder
meeting verifying the vote of such stockholders regarding such Business Combination;


 


(e)                
Provide the Representative with a copy of any Termination Letter(s) and/or any other correspondence that is sent to the
Trustee with respect to any proposed withdrawal from the Trust Account promptly after it issues the same;


 


(f)                  Unless
otherwise agreed in writing by the Company and the Representative, ensure that any Instruction Letter (as defined in Exhibit
A) delivered in connection with a Termination Letter in the form of Exhibit A expressly provides that the Deferred
Discount is paid directly to the account or accounts directed by the Representative on behalf of the Underwriters prior to
any transfer of the funds held in the Trust Account to the Company or any other person;


 






    3 


     


    

 


(g)               
 Instruct the Trustee to make only those distributions that are permitted under this Agreement, and refrain from instructing
the Trustee to make any distributions that are not permitted under this Agreement; and


 


(h)               
Within four (4) business days after the Underwriters exercise the over-allotment option (or any unexercised portion thereof)
or such over-allotment option expires, provide the Trustee with a notice in writing of the total amount of the Deferred Discount.


 


3.                  
Limitations of Liability. The Trustee shall have no responsibility or liability to:


 


(a)

than this Agreement and that which is expressly set forth herein;


 


(b)               
Take any action with respect to the Property, other than as directed in Section 1 hereof, and the Trustee shall have
no liability to any third party except for liability arising out of the Trustee’s gross negligence, fraud or willful misconduct;


 


(c)                
Institute any proceeding for the collection of any principal and income arising from, or institute, appear in or defend
any proceeding of any kind with respect to, any of the Property unless and until it shall have received instructions from the Company
given as provided herein to do so and the Company shall have advanced or guaranteed to it funds sufficient to pay any expenses
incident thereto;


 


(d)               
Refund any depreciation in principal of any Property;


 


(e)

to the Trustee;


 


(f)                 
The other parties hereto or to anyone else for any action taken or omitted by it, or any action suffered by it to be taken
or omitted, in good faith and in the Trustee’s best judgment, except for the Trustee’s gross negligence, fraud or willful
misconduct. The Trustee may rely conclusively and shall be protected in acting upon any order, notice, demand, certificate, opinion
or advice of counsel (including counsel chosen by the Trustee, which counsel may be the Company’s counsel), statement, instrument,
report or other paper or document (not only as to its due execution and the validity and effectiveness of its provisions, but also
as to the truth and acceptability of any information therein contained) which the Trustee believes, in good faith and with reasonable
care, to be genuine and to be signed or presented by the proper person or persons. The Trustee shall not be bound by any notice
or demand, or any waiver, modification, termination or rescission of this Agreement or any of the terms hereof, unless evidenced

are affected, unless it shall give its prior written consent thereto;


 


(g)               
Verify the accuracy of the information contained in the Registration Statement;


 


(h)               
Provide any assurance that any Business Combination entered into by the Company or any other action taken by the Company

earned on the Property;


 


(j)                 
Prepare, execute and file tax reports, income or other tax returns and pay any taxes with respect to any income generated

including, but not limited to, tax obligations, except pursuant to Section 1(j) hereof; or


 






    4 


     


    

 


(k)               
 Verify calculations, qualify or otherwise approve the Company’s written requests for distributions pursuant to Sections
1(i), 1(j) or 1(k) hereof.

to, or to any monies in, the Trust Account, and hereby irrevocably waives any Claim to, or to any monies in, the Trust Account
that it may have now or in the future. In the event the Trustee has any Claim against the Company under this Agreement, including,
without limitation, under Section 2(b) or Section 2(c) hereof, the Trustee shall pursue such
Claim solely against the Company and its assets outside the Trust Account and not against the Property or any monies in the Trust
Account.


 


5.                  
Termination. This Agreement shall terminate as follows:


 


(a)                
If the Trustee gives written notice to the Company that it desires to resign under this Agreement, the Company shall use
its reasonable efforts to locate a successor trustee, during which time the Trustee shall continue to act in accordance with this
Agreement. At such time that the Company notifies the Trustee that a successor trustee has been appointed by the Company and has
agreed to become subject to the terms of this Agreement, the Trustee shall transfer the management of the Trust Account to the
successor trustee, including but not limited to the transfer of copies of the reports and statements relating to the Trust Account,
whereupon this Agreement shall terminate; provided, however, that in the event that the Company does not locate
a successor trustee within ninety (90) days of receipt of the resignation notice from the Trustee, the Trustee may submit an application
to have the Property deposited with any court in the State of New York or with the United States District Court for the Southern
District of New York and upon such deposit, the Trustee shall be immune from any liability whatsoever; or


 


(b)               
At such time that the Trustee has completed the liquidation of the Trust Account and its obligations in accordance with
the provisions of Section 1(i) hereof and distributed the Property in accordance with the provisions of the Termination
Letter, this Agreement shall terminate except with respect to Section 2(b).


 


6.                  
Miscellaneous.


 


(a)                
The Company and the Trustee each acknowledge that the Trustee will follow the security procedures set forth below with respect
to funds transferred from the Trust Account. The Company and the Trustee will each restrict access to confidential information
relating to such security procedures to authorized persons. Each party must notify the other party immediately if it has reason
to believe unauthorized persons may have obtained access to such confidential information, or of any change in its authorized personnel.
In executing funds transfers, the Trustee shall rely upon all information supplied to it by the Company, including, account names,
account numbers, and all other identifying information relating to a Beneficiary, Beneficiary’s bank or intermediary bank.
Except for any liability arising out of the Trustee’s gross negligence, fraud or willful misconduct, the Trustee shall not
be liable for any loss, liability or expense resulting from any error in the information or transmission of the funds.


 


(b)               
This Agreement shall be governed by and construed and enforced in accordance with the laws of the State of New York. This
Agreement may be executed in several original or facsimile counterparts, each one of which shall constitute an original, and together
shall constitute but one instrument.


 


(c)                
This Agreement contains the entire agreement and understanding of the parties hereto with respect to the subject matter
hereof. Subject to Section 6(d) hereof, this Agreement or any provision hereof may only be changed, amended or modified (other
than to correct a typographical error) by a writing signed by each of the parties hereto.


 


(d)                This
Agreement or any provision hereof may only be changed, amended or modified pursuant to Section 6(c) hereof with the Consent
of the Stockholders. For purposes of this Section 6(d), the “Consent of the Stockholders” means receipt by the
Trustee of a certificate from the inspector of elections of the stockholder meeting certifying that the Company’s
stockholders of record as of a record date established in accordance with Section 213(a) of the Delaware General Corporation
Law, as amended (“DGCL”) (or any successor rule), who hold sixty-five percent (65%) or more of all then
outstanding shares of the Common Stock and Class B common stock, par value $0.0001 per share, of the Company voting together
as a single class, have voted in favor of such change, amendment or modification. No such amendment will affect any Public
Stockholder who has otherwise indicated his election to redeem his shares of Common Stock in connection with a stockholder
vote sought to amend this Agreement to modify the substance or timing of the Company’s obligation to redeem 100% of the
Common Stock if the Company does not complete its initial Business Combination within the time frame specified in the
Company’s amended and restated certificate of incorporation. Except for any liability arising out of the
Trustee’s gross negligence, fraud or willful misconduct, the Trustee may rely conclusively on the certification from
the inspector or elections referenced above and shall be relieved of all liability to any party for executing the proposed
amendment in reliance thereon.

Attn: Francis Wolf & Celeste Gonzalez


 


	 	Re:	Trust Account Termination Letter


 


Dear Mr. Wolf and Ms. Gonzalez:


 


Pursuant to Section 1(i) of
the Investment Management Trust Agreement between Integrated Energy Transition Acquisition Corp. (the “Company”)
and Continental Stock Transfer & Trust Company (“Trustee”), dated as of __________, 2021 (the “Trust
Agreement”), this is to advise you that the Company has entered into an agreement with ___________ (the “Target
Business”) to consummate a business combination with Target Business (the “Business Combination”)
on or about [insert date]. The Company shall notify you at least seventy-two (72) hours in advance of the actual date
(or such shorter period as you may agree) of the consummation of the Business Combination (the “Consummation Date”).
Capitalized terms used but not defined herein shall have the meanings set forth in the Trust Agreement.


 


In accordance with
the terms of the Trust Agreement, we hereby authorize you to commence to liquidate all of the assets of the Trust Account and to
transfer the proceeds to a segregated account held by you on behalf of the Beneficiaries to the effect that, on the Consummation
Date, all of the funds held in the Trust Operating Account at J.P. Morgan Chase Bank, N.A. will be immediately available for transfer
to the account or accounts that the Company shall direct on the Consummation Date (including as directed to it by the Representative
on behalf of the Underwriters (with respect to the Deferred Discount)).


 


On the Consummation
Date (i) counsel for the Company shall deliver to you written notification that the Business Combination has been consummated,
or will be consummated concurrently with your transfer of funds to the accounts as directed by the Company (the “Notification”),
and (ii) the Company shall deliver to you (a) a certificate by the Chief Executive Officer, Chief Financial Officer, Co-Executive
Chairman or Vice Chairman, which verifies that the Business Combination has been approved by a vote of the Company’s stockholders,
if a vote is held and (b) a joint written instruction signed by the Company and the Representative with respect to the transfer
