New York corporation (the “Trustee”).


 


WHEREAS, the Company’s registration
statement on Form S-1, File No. 333- 240267 (the “Registration Statement”) and prospectus (the “Prospectus”)
for the initial public offering of the Company’s units (the “Units”), each of which consists of

(such initial public offering hereinafter referred to as the “Offering”), 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 Credit Suisse Securities (USA) LLC, as representative
(the “Representative”) to the several underwriters (the “Underwriters”) named
therein; and


 


WHEREAS, as described in the Prospectus,
$350,000,000 of the gross proceeds of the Offering and sale of the Private Placement Warrants (as defined in the Underwriting Agreement)
(or $402,500,000 if the Underwriter’s option to purchase additional units 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 shares of 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”); and


 


WHEREAS, pursuant to the Underwriting Agreement,
a portion of the Property equal to $12,250,000, or $14,087,500 if the Underwriter’s option to purchase additional units is
exercised in full, is attributable to deferred underwriting discounts and commissions that will be payable by the Company to the
Underwriter upon 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 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;

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; the Trustee may not invest in any other securities or assets,
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;

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 or other authorized officer of the Company, 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 us to pay our income 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
certificate of incorporation (as amended), 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 income 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. It is acknowledged and agreed that there should be no reduction
in the principal amount per share initially deposited in the Trust Account;


 


(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 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 to the remitting brokers on behalf of Public Stockholders redeeming Common Stock the amount required to pay redeemed
Common Stock from Public Stockholders pursuant to the Company’s certificate of incorporation (as amended); and

Give all instructions to the Trustee hereunder in writing, signed by the Company’s Chief Executive Officer,
Chief Financial Officer or other authorized officer of the Company. In addition, except with respect to its duties under Sections
1(i), (j) or (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(k) 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) and as may be provided in Section 2(b) hereof;


 


(d)               
In connection with any vote of the Company’s stockholders regarding a merger, share exchange, asset acquisition,
share 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 between 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;


 


(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;


 









    3


     


    

 


(h)

substance or timing of the Company’s obligation to provide holders of the Common Stock the right to have their shares redeemed
in connection with the Company’s initial Business Combination or to redeem 100% of the Common Stock if the Company does not
complete its initial Business Combination within the time period set forth therein or (B) with respect to any other provision relating
to the rights of holders of the Common Stock (in each case, an “Amendment”), the Company will provide
the Trustee with a letter (an “Amendment Notification Letter”) in the form of Exhibit D providing
instructions for the distribution of funds to Public Stockholders who exercise their redemption option in connection with such
Amendment; and


 


(i)

portion thereof) or such option to purchase additional units expires, provide the Trustee with a notice in writing of the total
amount of the Deferred Discount.

(c)

(g)               
The other parties hereto or to anyone else for any action taken or omitted by it, or any action suffered by it to

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

(k)

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


 


(l)                 
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, pending which 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

This Agreement shall be governed by and construed and enforced in accordance with the laws of the State of New York,
without giving effect to conflicts of law principles that would result in the application of the substantive laws of another jurisdiction.
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.
Except for Section 1(i), 1(j) and 1(k) hereof (which sections may not be modified, amended or deleted
without the affirmative vote of sixty-five percent (65%) of the then outstanding Common Stock and Class B common stock, par
value $0.0001 per share, of the Company, voting together as a single class; provided that no such amendment will

vote to amend this Agreement to modify the substance or timing of the Company’s obligation to provide for the
redemption of the Common Stock in connection with an initial Business Combination or an Amendment or to redeem 100% of its

Continental Stock Transfer & Trust Company


1 State Street, 30th Floor

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 Star Peak Energy Transition Corp. (the “Company”) and Continental
Stock Transfer & Trust Company (“Trustee”), dated as of August [●], 2020 (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 time 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
into the trust operating account at J.P. Morgan Chase Bank, N.A. to the effect that, on the Consummation Date, all of the funds
held in the Trust Account will be immediately available for transfer to the account or accounts that the Representative (with respect
to the Deferred Discount) and the Company shall direct on the Consummation Date. It is acknowledged and agreed that while the funds
are on deposit in said trust operating account at J.P. Morgan Chase Bank, N.A. awaiting distribution, neither the Company nor the
Representative will earn any interest or dividends.


 


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
substantially 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 or other authorized
officer of the Company, which verifies that the Business Combination has been approved by a vote of the Company’s stockholders,
if a vote is held and (b) 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 the Deferred Discount 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
