Re: Initial Public Offering


 


Ladies and Gentlemen:


 


This letter agreement (this “Letter
Agreement”) is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”)
to be entered into by and between CENAQ Energy Corp., a Delaware corporation (the “Company”), and Imperial Capital,
LLC, as representative (the “Representative”) of the several underwriters (each, an “Underwriter”
and collectively the “Underwriters”), relating to an underwritten initial public offering (the “Public
Offering”), of 15,000,000 of the Company’s units (including up to 2,250,000 units that may be purchased to cover
over-allotments, if any) (the “Units”), each comprised 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 warrant. Each whole warrant (each, a “Warrant”)
entitles the holder thereof to purchase one share of Common Stock at a price of $11.50 per share, subject to adjustment. The Units
shall be sold in the Public Offering pursuant to a registration statement on Form S-1 and prospectus (the “Prospectus”)
filed by the Company with the Securities and Exchange Commission (the “Commission”), and the Company shall apply
to have the Units listed on the NASDAQ Capital Market. Certain capitalized terms used herein are defined in paragraph 11 hereof.


 


In order to induce the Company and the
Underwriters to enter into the Underwriting Agreement and to proceed with the Public Offering and for other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, CENAQ Sponsor LLC (the “Sponsor”) and each of
the undersigned individuals, each of whom is a member of the Company’s board of directors and/or management team (each, an
“Insider” and collectively, the “Insiders”), hereby agrees with the Company as follows:


 


1. The
Sponsor and each Insider agrees that if the Company seeks stockholder approval of a proposed Business Combination, then in connection
with such proposed Business Combination, it, he or she shall (i) vote any shares of Capital Stock owned by it, him or her in favor
of any proposed Business Combination and (ii) not redeem any shares of Common Stock owned by it, him or her in connection with
such stockholder approval.


 






    1


     


    

 


2. The
Sponsor and each Insider hereby agrees that in the event that the Company fails to consummate a Business Combination within 24
months from the closing of the Public Offering, or such later period as may be approved by the Company’s stockholders in
accordance with the Company’s amended and restated certificate of incorporation, the Sponsor and each Insider shall take
all reasonable steps to cause the Company to (i) cease all operations except for the purpose of winding up, (ii) as promptly as
reasonably possible but not more than 10 business days thereafter, subject to lawfully available funds therefor, redeem 100% of
the Common Stock sold as part of the Units in the Public Offering (the “Offering Shares”), at a per-share price,
payable in cash, equal to the aggregate amount then on deposit 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 franchise and income taxes as well as any expenses related
to the administration of the Trust Account (less up to $100,000 of interest to pay dissolution expenses), divided by the number
of then outstanding Offering Shares, which redemption will completely extinguish all of the Public Stockholders’ rights as
stockholders (including the right to receive further liquidation distributions, if any), subject to applicable law and (iii) as
promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining stockholders
and the Company’s board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under
Delaware law to provide for claims of creditors and other requirements of applicable law. The Sponsor and each Insider agree not
to propose any amendment to the Company’s amended and restated certificate of incorporation that would modify (a) the substance
or timing of the Company’s obligation to redeem 100% of the Offering Shares if the Company does not complete a Business Combination
within 24 months from the closing of the Public Offering or (b) any provisions of the Company’s amended and restated certificate
of incorporation relating to stockholders’ rights or pre-initial Business Combination activity, unless the Company provides
its Public Stockholders with the opportunity to redeem their Offering Shares upon approval of any such amendment at a per-share
price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest not previously released
to the Company to pay its franchise and income taxes as well as any expenses related to the administration of the Trust Account,
divided by the number of then outstanding Offering Shares.


 


The Sponsor and each
Insider acknowledges that it, he or she has no right, title, interest or claim of any kind in or to any monies held in the Trust
Account or any other asset of the Company as a result of any liquidation of the Company with respect to the Founder Shares held
by it, him or her. The Sponsor and each Insider hereby further waives, with respect to any shares of Common Stock held by it, him
or her, if any, any redemption rights it, he or she may have in connection with the consummation of a Business Combination, including,
without limitation, any such rights available in the context of a stockholder vote to approve such Business Combination or in the
context of a tender offer made by the Company to purchase shares of Common Stock (although the Sponsor, the Insiders and their
respective affiliates shall be entitled to redemption and liquidation rights with respect to any Offering Shares it, he, she or
they hold if the Company fails to consummate a Business Combination within 24 months from the date of the closing of the Public
Offering).


 


3. During
the period commencing on the effective date of the Underwriting Agreement and ending 180 days after such date, the Sponsor and
each Insider shall not, without the prior written consent of the Representative, (i) sell, offer to sell, contract or agree to
sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly,
or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section
16 of the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission promulgated thereunder,
with respect to any Units, shares of Common Stock, Founder Shares, Warrants or any securities convertible into, or exercisable,
or exchangeable for, shares of Common Stock owned by it, him or her, (ii) enter into any swap or other arrangement that transfers
to another, in whole or in part, any of the economic consequences of ownership of any Units, shares of Common Stock, Founder Shares,
Warrants or any securities convertible into, or exercisable, or exchangeable for, shares of Common Stock owned by it, him or her,
whether any such transaction is to be settled by delivery of such securities, in cash or otherwise or (iii) publicly announce any
intention to effect any transaction specified in clause (i) or (ii). The provisions of this paragraph will not apply if the release
or waiver is effected solely to permit a transfer not for consideration and the transferee has agreed in writing to be bound by
the same terms described in this Letter Agreement to the extent and for the duration that such terms remain in effect at the time
of the transfer.

4. In
the event of the liquidation of the Trust Account, the Sponsor (which for purposes of clarification shall not extend to any other
shareholders, members or managers of the Sponsor) agrees to indemnify and hold harmless the Company against any and all loss, liability,
claim, damage and expense whatsoever (including, but not limited to, any and all legal or other expenses reasonably incurred in
investigating, preparing or defending against any litigation, whether pending or threatened, or any claim whatsoever) to which
the Company may become subject as a result of any claim by (i) any third party for services rendered or products sold to the Company
or (ii) a prospective target business with which the Company has entered into an acquisition agreement (a “Target”);
provided, however, that such indemnification of the Company by the Sponsor shall apply only to the extent necessary to ensure that
such claims by a third party for services rendered or products sold to the Company or a Target do not reduce the amount of funds
in the Trust Account to below (i) $10.00 per Offering Share or (ii) such lesser amount per Offering Share held in the Trust Account
due to reductions in the value of the trust assets as of the date of the liquidation of the Trust Account, in each case, net of
the amount of interest earned on the property in the Trust Account which may be withdrawn to pay taxes and expenses related to
the administration of the Trust Account, except as to any claims by a third party (including a Target) who executed a waiver of
any and all rights to seek access to the Trust Account and except as to any claims under the Company’s indemnity of the Underwriters
against certain liabilities, including liabilities under the Securities Act of 1933, as amended. In the event that any such executed
waiver is deemed to be unenforceable against such third party, the Sponsor shall not be responsible to the extent of any liability
for such third party claims. The Sponsor shall have the right to defend against any such claim with counsel of its choice reasonably
satisfactory to the Company if, within 15 days following written receipt of notice of the claim to the Sponsor, the Sponsor notifies
the Company in writing that it shall undertake such defense.


 


5. To
the extent that the Underwriters do not exercise their over-allotment option to purchase up to an additional 2,250,000 Units within
45 days from the date of the Prospectus (and as further described in the Prospectus), the Sponsor agrees to forfeit, at no cost,
a number of Founder Shares in the aggregate equal to 562,500 multiplied by a fraction, (i) the numerator of which is 2,250,000
minus the number of Units purchased by the Underwriters upon the exercise of their over-allotment option, and (ii) the denominator
of which is 2,250,000. The forfeiture will be adjusted to the extent that the over-allotment option is not exercised in full by
the Underwriters so that the Initial Stockholders will own an aggregate of 20.0% of the Company’s issued and outstanding
shares of Capital Stock after the Public Offering.


 






    3


     


    

 


6. The
Sponsor and each Insider hereby agrees and acknowledges that: (i) the Underwriters and the Company would be irreparably injured
in the event of a breach by such Sponsor or Insider of its, his or her obligations under paragraphs 1, 2, 3, 4, 5, 7(a), 7(b),
and 9 of this Letter Agreement, (ii) monetary damages may not be an adequate remedy for such breach and (iii) the non-breaching
party shall be entitled to injunctive relief, in addition to any other remedy that such party may have in law or in equity, in
the event of such breach.


 


7. (a)
The Sponsor and each Insider agrees that it, he or she shall not Transfer any Founder Shares (or shares of Common Stock issuable
upon conversion thereof) until the earlier of (A) six months year after the completion of the Company’s initial Business
Combination or (B) subsequent to the Business Combination, (x) if the last sale price of the Common Stock equals or exceeds $12.00
per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days
within any 30-trading day period commencing at least 75 days after the Company’s initial Business Combination or (y) the
date on which the Company completes a liquidation, merger, capital stock exchange, reorganization or other similar transaction
that results in all of the Company’s stockholders having the right to exchange their shares of Common Stock for cash, securities
or other property (the “Founder Shares Lock-up Period”).


 


(b) The Sponsor and
each Insider agrees that it, he or she shall not Transfer any Private Placement Warrants (or shares of Common Stock issued or issuable
upon the exercise of the Private Placement Warrants), until 30 days after the completion of a Business Combination (the “Private
Placement Warrants Lock-up Period” and, together with the Founder Shares Lock-up Period, the “Lock-up Periods”).


 


(c) Notwithstanding
the provisions set forth in paragraphs 7(a) and (b), Transfers of the Founder Shares, Private Placement Warrants and shares of
Common Stock issued or issuable upon the exercise or conversion of the Private Placement Warrants or the Founder Shares, as applicable,
and that are held by the Sponsor, an Insider or any of their permitted transferees (that have complied with this paragraph 7(c)),
are permitted (a) to the Company’s officers, directors, any affiliates or family members of any of the Company’s officers,
directors, any members of the Sponsor or any affiliates of the Sponsor; (b) in the case of an individual, transfers by gift to
a member of the individual’s immediate family, to a trust, the beneficiary of which is a member of the individual’s
immediate family or an affiliate of such person, or to a charitable organization; (c) in the case of an individual, transfers by
virtue of laws of descent and distribution upon death of the individual; (d) in the case of an individual, transfers pursuant to
a qualified domestic relations order; (e) transfers by private sales or transfers made in connection with the consummation of a
Business Combination at prices no greater than the price at which the securities were originally purchased; (f) transfers in the
event of the Company’s liquidation prior to the completion of an initial Business Combination; (g) transfers by virtue of
the laws of the State of Delaware or the Sponsor’s limited liability company agreement upon dissolution of the Sponsor; and
(h) in the event of the Company’s liquidation, merger, capital stock exchange, reorganization or other similar transaction
which results in all of the Company’s stockholders having the right to exchange their shares of Common Stock for cash, securities
or other property subsequent to the completion of the Company’s initial Business Combination; provided, however, that in
the case of clauses (a) through (g), these permitted transferees must enter into a written agreement agreeing to be bound by the
restrictions herein.

8. The
Sponsor and each Insider represents and warrants that it, he or she has never been suspended or expelled from membership in any
securities or commodities exchange or association or had a securities or commodities license or registration denied, suspended
or revoked. Each Insider’s biographical information furnished to the Company (including any such information included in
the Prospectus) is true and accurate in all respects and does not omit any material information with respect to the Insider’s
background. The questionnaire of the Sponsor and each Insider furnished to the Company is true and accurate in all respects.


 


9. The
Sponsor and each Insider represents and warrants that: it, he or she is not subject to or a respondent in any legal action for,
any injunction, cease-and-desist order or order or stipulation to desist or refrain from any act or practice relating to the offering
of securities in any jurisdiction; it, he or she has never been convicted of, or pleaded guilty to, any crime (i) involving fraud,
(ii) relating to any financial transaction or handling of funds of another person or (iii) pertaining to any dealings in any securities
and it, he or she is not currently a defendant in any such criminal proceeding.


 


10. Except
as disclosed in the Prospectus, neither the Sponsor nor any Insider nor any affiliate of the Sponsor or any Insider, nor any director
or officer of the Company, shall receive from the Company any finder’s fee, reimbursement, consulting fee, monies in respect
of any repayment of a loan or other compensation prior to, or in connection with any services rendered in order to effectuate the
consummation of the Company’s initial Business Combination (regardless of the type of transaction that it is), other than
the following, none of which will be made from the proceeds held in the Trust Account prior to the completion of the initial Business
Combination: (a) reimbursement for any out-of-pocket expenses related to the Company’s formation and Public Offering and
to identifying, investigating and completing an initial Business Combination; (b) repayment of loans, if any, and on such terms
as to be determined by the Company from time to time, made by the Sponsor or any Insider or any of the Company’s officers
or directors to finance transaction costs in connection with an intended initial Business Combination, provided, that, if the Company
does not consummate an initial Business Combination, a portion of the working capital held outside the Trust Account may be used
by the Company to repay such loaned amounts so long as no proceeds from the Trust Account are used for such repayment; and (c)
payments to the Sponsor, any Insiders or their respective affiliates in connection with the successful completion of the Company’s
initial Business Combination. Up to $1,500,000 of the loans referenced in clause (b) above may be convertible into warrants at
a price of $1.00 per warrant at the option of the lender. Such warrants would be identical to the Private Placement Warrants, including
as to exercise price, exercisability and exercise period.


 


11. The
Sponsor and each Insider has full right and power, without violating any agreement to which it is bound (including, without limitation,
any non-competition or non-solicitation agreement with any employer or former employer), to enter into this Letter Agreement and,
as applicable, to serve as an officer and/or a director on the board of directors of the Company and hereby consents to being named
in the Prospectus as an officer and/or director of the Company.

17. This
Letter Agreement shall be deemed severable, and the invalidity or unenforceability of any term or provision hereof shall not affect
the validity or enforceability of this Letter Agreement or of any other term or provision hereof. Furthermore, in lieu of any such
