INVESTMENT MANAGEMENT TRUST AGREEMENT


 


This Investment Management
Trust Agreement (this “Agreement”) is made effective as of [______], 2021 by and between Integrated Energy
Transition Acquisition Corp., a Delaware corporation (the “Company”), and Continental Stock Transfer &
Trust Company, a New York corporation (the “Trustee”).


 


WHEREAS, the Company’s
registration statement on Form S-1, File No. [______] (the “Registration Statement”) and prospectus
(the “Prospectus”) for its initial public offering (the “Offering”) of the
Company’s units (the “Units”), each of which consists of one share of the Company’s Class A
common stock, par value $0.0001 per share (the “Common Stock”), and one-half of one redeemable warrant,
each whole warrant entitling the holder thereof to purchase one share of Common Stock, has been declared effective as of the date
hereof by the U.S. Securities and Exchange Commission; and


 


WHEREAS, the
Company has entered into an Underwriting Agreement (the “Underwriting Agreement”) with Stifel,
Nicolaus & Company, Incorporated, as representative (the “Representative”) of the
several underwriters (the “Underwriters”) named therein; and


 


WHEREAS,
as described in the Prospectus, $150,000,000 of the gross proceeds of the Offering and sale of the Private Placement Warrants (as
defined in the Underwriting Agreement) (or $172,500,000 if the Underwriters’ over-allotment option is exercised in full)
will be delivered to the Trustee to be deposited and held in a segregated trust account located at all times in the United States
(the “Trust Account”) for the benefit of the Company and the holders of the Common Stock included in
the Units issued in the Offering as hereinafter provided (the amount to be delivered to the Trustee (and any interest subsequently
earned thereon) is referred to herein as the “Property,” the stockholders for whose benefit the
Trustee shall hold the Property will be referred to as the “Public Stockholders,” and the Public Stockholders
and the Company will be referred to together as the “Beneficiaries”);


 


WHEREAS,
pursuant to the Underwriting Agreement, a portion of the Property equal to $5,250,000, or $6,037,500 if the Underwriters’
over- allotment option is exercised in full, is attributable to deferred underwriting discounts and commissions that will be payable
by the Company to the Underwriters upon and concurrently with the consummation of the Business Combination (as defined below) (the
 “Deferred Discount”); and


 


WHEREAS, the Company
and the Trustee desire to enter into this Agreement to set forth the terms and conditions pursuant to which the Trustee shall hold
the Property.


 


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 government
securities within the meaning of Section 2(a)(16) of the Investment Company Act of 1940, as amended, having a maturity 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 redemptions 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)            Imply
obligations, perform duties, inquire or otherwise be subject to the provisions of any agreement or document other 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)            Assume
that the authority of any person designated by the Company to give instructions hereunder shall not be continuing unless provided
otherwise in such designation, or unless the Company shall have delivered a written revocation of such authority 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
by a written instrument delivered to the Trustee, signed by the proper party or parties and, if the duties or rights of the Trustee
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 is as contemplated
by the Registration Statement;


 


(i)            File
information returns with respect to the Trust Account with any local, state or federal taxing authority or provide periodic written
statements to the Company documenting the taxes payable by the Company, if any, relating to any interest income 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 by, and activities
relating to, the Trust Account, regardless of whether such tax is payable by the Trust Account or the Company, 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.


 


4.            Trust
Account Waiver. The Trustee has no right of set-off or any right, title, interest or claim of any kind (“Claim”)
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.

AGREEMENT, EACH PARTY WAIVES THE RIGHT TO TRIAL BY JURY.

	 	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 of the funds held in the Trust Account, including payment of amounts owed to public stockholders who have properly
exercised their redemption rights and payment of the Deferred Discount directly to the account or accounts directed by the Representative
from the Trust Account (the “Instruction Letter”). You are hereby directed and authorized to transfer
the funds held in the Trust Account immediately upon your receipt of the Notification and the Instruction Letter, in accordance
with the terms of the Instruction Letter. In the event that certain deposits held in the Trust Account may not be liquidated by
the Consummation Date without penalty, you will notify the Company in writing of the same and the Company shall direct you as to
whether such funds should remain in the Trust Account and be distributed after the Consummation Date to the Company. Upon the distribution
of all the funds, net of any payments necessary for reasonable unreimbursed expenses related to liquidating the Trust Account,
your obligations under the Trust Agreement shall be terminated.


 


In the event that the
Business Combination is not consummated on the Consummation Date described in the notice thereof and we have not notified you on
or before the original Consummation Date of a new Consummation Date, then upon receipt by the Trustee of written instructions from
the Company, the funds held in the Trust Account shall be reinvested as provided in Section 1(c) of the Trust Agreement
on the business day immediately following the Consummation Date as set forth in such notice as soon thereafter as possible.
