in the United States 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;

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; the Trustee shall 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 credit
or other consideration;


 


(d)                Collect
and receive, when due, all 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 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 or in connection with the preparation or completion of the
audit of the Company’s financial statements by the Company’s auditors;


 


(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 and account balances of the Trust Account, including a record of 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, President
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 funds held in the Trust Account and not previously released to the Company to pay its franchise
and income taxes (less up to $105,000 of interest that may be released to the Company to pay dissolution expenses and net of taxes payable),
only as directed in the Termination Letter and any other documents referred to therein, or (y) 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 (the “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
funds held in the Trust Account and not previously released to the Company to pay its franchise and income taxes (net of amounts withdrawn
in accordance with this Agreement and less up to $105,000 of interest that may be released to the Company 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 income or franchise 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; 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, so long as there is no reduction in the principal amount per share initially deposited in the Trust Account; provided,
further, that if the tax to be paid is a franchise tax, the written request by the Company to make such distribution shall be
accompanied by a copy of the franchise tax bill from the relevant taxing authority for the Company. 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;


 






    2


     


    

 


(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 Public Stockholders
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 Certificate of Incorporation (i) to modify the substance
or timing of the Company’s obligation to redeem 100% of its public shares of Common Stock if the Company has not consummated an
initial Business Combination within such time as is described in the Certificate of Incorporation or (ii) with respect to any other material
provision relating to the rights of holders of Common Stock 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


 


(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 Chief Executive Officer, Chief Financial Officer,
President or another authorized officer of the Company. 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 documented expenses, including
reasonable outside 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 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 or its representatives’ 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; provided, further that the Company may conduct and manage the defense
against any Indemnified Claim if the Trustee does not promptly take reasonable steps to mount such a defense. The Trustee may not agree
to settle any Indemnified Claim without the prior written consent of the Company. The Company may participate in any such action with
its own counsel;


 






    3


     


    

 


(c)                Pay
the Trustee the fees set forth on Schedule A hereto, including an initial set-up 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) hereof. The Company
shall pay the Trustee the initial set-up 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 Underwriters 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)                 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


 


(g)                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, which shall in no event be
less than $12,250,000, or $14,087,500 if the Underwriters’ over-allotment option is exercised in full.


 


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

obligations, perform duties, inquire or otherwise be subject to the provisions of any agreement or document other than this Agreement

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 written 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 reasonably incurred expenses incident
thereto;


 


(d)                Refund

    4


     


    

 


(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
Company 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 or its representatives’ 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

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,
franchise and income tax obligations, except pursuant to Section 1(j) hereof; or


 


(k)                Verify calculations, qualify or otherwise approve the Company’s written requests for distributions pursuant to Sections
1(i), 1(j) and 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 and Replacement of Trustee. 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 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 related to the Trust Account and any other reasonable transfer requests that the Company may make,
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


 






    5


     


    

 


(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
or its representatives’ 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, without giving effect
to conflicts of law principles that would result in the application of the substantive laws of another jurisdiction.


 


(c)                This
Agreement contains the entire agreement and understanding of the parties hereto with respect to the subject matter hereof. Except as
provided for in Section 6(d), 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)               Sections 1(i) and 1(k) hereof may only be changed, amended or modified pursuant to Section 6(c) hereof with the Consent
of the Stockholders, it being the specific intention of the parties hereto that each of the Company’s stockholders is, and shall
be, a third party beneficiary of this Section 6(d) with the same right and power to enforce this Section 6(d) as the other
parties hereto. 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 share of Common
Stock in connection with a stockholder vote sought to amend the Certificate of Incorporation. Except for any liability arising out of
the Trustee’s or its representatives’ gross negligence, fraud or willful misconduct, the Trustee may rely conclusively on
the certification from the inspector of elections referenced above and shall be relieved of all liability to any party for executing the
proposed amendment in reliance thereon.

(e)               
The parties hereto consent to the jurisdiction and venue of any state or federal court located in the City of New York, County
of New York, State of New York, for purposes of resolving any disputes hereunder. AS TO ANY CLAIM, CROSS-CLAIM OR COUNTERCLAIM IN ANY
WAY RELATING TO THIS AGREEMENT, EACH PARTY WAIVES THE RIGHT TO TRIAL BY JURY.


 


(f)                
Any notice, consent or request to be given in connection with any of the terms or provisions of this Agreement shall be in writing

Attn: Francis Wolf and 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 Zimmer Energy Transition Acquisition Corp. (the “Company”) and Continental Stock Transfer &
Trust Company (the “Trustee”), dated as of [●], 2021 (the “Trust Agreement”), this is to advise
you that the Company has entered into an agreement with [insert name] (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 (or such shorter time period as you may agree) in advance of the actual date 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 JPMorgan 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 Company shall direct on the Consummation Date (including as directed
to it by the Underwriters with respect to the Deferred Discount). It is acknowledged and agreed that while the funds are on deposit in
the trust operating account at JPMorgan Chase Bank, N.A. awaiting distribution, the Company will not 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 of the Chief Executive 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) a joint written instruction signed by the Company and
the Underwriters with respect to the transfer of the funds held in the Trust Account, including payment of the Deferred Discount to the
account or accounts directed by the Underwriters 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
