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

N.A. 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 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,
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;


 






     


     


    

 


(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;


 


(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, President, Chief Financial Officer, Secretary or Chairman of the board
of directors of the Company (the “Board”) 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 not previously released to the Company to pay
its franchise and income taxes as well as expenses relating to the administration of the trust account (less up to $100,000 of interest
that may be released to the Company 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) 18 months after the closing of the Offering, provided that the Company may, but is not obligated to, extend the period of time to consummate its initial Business Combination (as
defined below) two times by an additional three months each time (for a total of up to 24 months to complete its initial Business Combination);
further provided that upon each 3-month extension of the period of time to consummate an initial Business Combination, unless the Company
files the Sponsor (or its designees) must deposit into the Trust Account funds equal to one percent (1%) of the gross proceeds of the
Offering (including such proceeds from the exercise of the underwriters’ over-allotment option, if exercised) in exchange for a
non-interest bearing, unsecured promissory note; and further provided that if the Company filed a proxy statement, registration statement
or similar filing for an initial Business Combination within the initial 18-month period, it may extend the period of time to consummate
a Business Combination by three months (or up to 21 months to complete a Business Combination) without the deposit of the additional funds; 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 not previously released to the Company to pay its franchise and income taxes as well as expenses relating to the administration
of the trust account (less up to $100,000 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; provided, however, that in the event the Trustee receives a Termination
Letter in a form substantially similar to Exhibit B hereto, or if the Trustee begins to liquidate the Property because it has received
no such Termination Letter by the date specified in clause (y) of this Section 1(i), the Trustee shall keep the Trust Account open
until twelve (12) months following the date the Property has been distributed to the Public Stockholders;


 


(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; 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 State of Delaware for the Company and a written statement from the principal financial officer
of the Company setting forth the actual amount payable. 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 (i) that would affect 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 Company’s amended and restated certificate of incorporation or (ii) relating
to any provisions of the Company’s amended and restated certificate of incorporation 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


 


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

Officer or Secretary. 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(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 Trustee shall refund to the Company the annual administration fee (on a pro rata basis) with respect to any period after the liquidation
of the Trust Account. 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) 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 $5,250,000.

(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

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

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

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.

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

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
(which section may not be amended under any circumstances) 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

not complete its initial Business Combination within the time frame specified in the Company’s amended and restated certificate
of incorporation) or (ii) relating to any provisions of the Company’s amended and restated certificate of incorporation relating

Ladies and Gentlemen:


 


Pursuant to Section 1(i)
of the Investment Management Trust Agreement between CENAQ Energy 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 (the “Target Business”) to consummate
a business combination with Target Business (the “Business Combination”) on or about ___________, 20__. The
Company shall notify you at least forty-eight (48) hours 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 on _______, 20__ and to
transfer the proceeds into the trust operating account at Bank of America, 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. It is acknowledged and agreed that while the funds are on deposit in the trust operating account at Bank of America,
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
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) written instruction signed by the
Company 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 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 written instructions as soon thereafter as possible.
