Re:     Initial
Public Offering


 


Ladies and Gentlemen:


 


This letter (this “Letter
Agreement”) is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”)
entered into by and among Nabors Energy Transition Corp., a Delaware corporation (the “Company”), Citigroup
Global Markets Inc. and Wells Fargo Securities, LLC as underwriters (the “Underwriters”), relating to an underwritten
initial public offering (the “Public Offering”), of up to 27,600,000 of the Company’s units (including
up to 3,600,000 units which 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 “Class A Common Stock”),
and one-half of one redeemable warrant (each whole warrant, a “Warrant”). Each Warrant entitles the holder thereof
to purchase one share of Class A Common Stock at a price of $11.50 per share, subject to adjustment. The Units shall be sold in the
Public Offering pursuant to the registration statement on Form S-1 (File No. 333-256876) 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 New York Stock Exchange. 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, Nabors Energy Transition Sponsor LLC, a Delaware limited
liability company (the “Sponsor”), and each of the undersigned individuals, each of whom is a member of the
Company’s board of directors (the “Board”) and/or management team (each an “Insider”
and, collectively, the “Insiders”), hereby agrees with the Company as follows:


 


1.            The
Sponsor and each Insider agree 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 vote all Founder Shares and any shares acquired by it, him or her in the Public
Offering or the secondary public market in favor of such proposed Business Combination.


 


2.            The
Sponsor and each Insider hereby agree that in the event that the Company fails to consummate a Business Combination within 15 months
from the closing of the Public Offering, or up to 21 months from the closing of the Public Offering if the Company has extended the period
of time to consummate a Business Combination, or such later period approved by the Company’s stockholders, in accordance with the
Company’s amended and restated certificate of incorporation, as may be amended from time to time (the “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 Class A 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 taxes (less up to $100,000 of interest to pay dissolution expenses and net of taxes payable), divided by the number
of then outstanding Offering Shares, which redemption will completely extinguish the Public Stockholders’ rights as stockholders
(including the right to receive further liquidating 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 Board, 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 to not propose any amendment to the Certificate of Incorporation (A) in
a manner that would affect the substance or timing of the Company’s obligation to redeem 100% of the Offering Shares if the Company
does not complete an initial Business Combination within 15 months (or up to 21 months, as applicable) from the closing of the Public
Offering or (B) with respect to any other material provision relating to the rights of holders of Offering Shares 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 earned on the funds held in the Trust Account and not previously released to the Company to pay its taxes,
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. The Sponsor and each Insider
hereby further waives, with respect to any shares of the Class A Common Stock held by it, him or her, any redemption rights it, he
or she may have in connection with the consummation of an initial Business Combination, including, without limitation, any such rights
available in the context of a stockholder vote to approve such initial Business Combination or in the context of a tender offer made by
the Company to purchase shares of the Class A Common Stock and in connection with a stockholder vote to amend the Company’s
Certificate of Incorporation in a manner that would affect the substance or timing of the Company’s obligation to redeem 100% of
the Offering Shares if the Company has not consummated an initial Business Combination within 15 months from the closing of the Public
Offering (or up to 21 months, as applicable) (although the Sponsor, the Insiders and their respective affiliates shall be entitled to
redemption and liquidation rights with respect to any shares of the Class A Common Stock (other than the Founder Shares) it or they
hold if the Company fails to consummate an initial Business Combination within 15 months from the date of the closing of the Public Offering
(or up to 21 months, as applicable) or such later date as may be specified in an amendment to the Company’s Certificate of Incorporation).


 


To the fullest extent permitted
by applicable law, the Company hereby agrees to defend, indemnify, hold harmless and exonerate (including the advancement of expenses
to the fullest extent permitted by applicable law) the Sponsor, its affiliates and their respective present and former officers and directors
(each, a “Sponsor Indemnitee”) from any and all costs, fees, expenses, judgments, liabilities, fines, penalties,
reasonable attorneys’ fees and amounts paid in settlement (including all interest, assessments and other charges paid or payable
in connection with or in respect of such costs, fees, expenses, judgments, liabilities, fines, penalties and amounts paid in settlement)
actually, and reasonably, incurred by a Sponsor Indemnitee or on a Sponsor Indemnitee’s behalf in connection with any threatened,
pending or completed action, suit, arbitration, mediation, alternate dispute resolution mechanism, investigation, inquiry, hearing or
any other actual, threatened or completed proceeding instituted by the Company or any third party, whether civil, criminal, administrative
or investigative in nature, in respect of any investment opportunities sourced by a Sponsor Indemnitee for the Company or any liability
arising with respect to a Sponsor Indemnitee’s activities in connection with the affairs of the Company (in each case to the extent
that such indemnification, hold harmless and exoneration obligations with respect to such matters are not expressly covered by a separate
written agreement between the Company and the applicable Sponsor Indemnitee); provided, that in no event shall a Sponsor Indemnitee be
entitled to be indemnified or held harmless hereunder in respect of any costs, fees, expenses, judgments, liabilities, fines, penalties
and amounts paid in settlement (if any) that Sponsor Indemnitee may incur by reason of such person’s own actual fraud or intentional
misconduct; provided further, for the avoidance of doubt, that under no circumstance shall a Sponsor Indemnitee have a claim to any monies
or assets held in the Trust Account, and the Company shall not be permitted to procure monies or assets held in the Trust Account for
the satisfaction of its obligations to any Sponsor Indemnitee in respect of the indemnification provided hereunder. The Sponsor Indemnitees
shall be third party beneficiaries of this paragraph.


 


3.            During
the period commencing on the effective date of the Underwriting Agreement and ending 180 days after such date, the undersigned shall
not, without the prior written consent of the Underwriters, except (a) issuances of shares of Class B common stock of the Company,
par value $0.0001 per share (the “Class B Common Stock”), upon the conversion or exchange of shares of
Class F common stock of the Company, par value $0.0001 per share (the “Class F Common Stock” and,
together with the Class A Common Stock and the Class B Common Stock, the “Common Stock”), (b) issuances
of shares of Class A Common Stock upon the conversion or exchange of shares of Class B Common Stock and (c) issuances
of Founder Shares upon the forfeiture by the Sponsor to the Company of an identical number of Founder Shares, (i) sell, offer to
sell, contract or agree to sell, hypothecate, pledge, 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 (the “Exchange Act”), and the rules and regulations of the
Commission promulgated thereunder, any Units, shares of Class A Common Stock, shares of Class B Common Stock, shares of Class F
Common Stock, Warrants or any securities convertible into, or exercisable, or exchangeable for, shares of Common Stock owned by him,
her or it; or (ii) publicly announce any intention to effect any transaction specified in clause (i). If the undersigned is
an officer or director of the Company, the undersigned further agrees that the foregoing restrictions shall be equally applicable to
any issuer-directed Units that the undersigned may purchase in the Public Offering.


 






     


     


    

 


4.            In
the event of the liquidation of the Trust Account, the Sponsor (which for purposes of clarification shall not extend to any officer, member
or manager 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 (other than the Company’s independent public accountants) for services rendered or products
sold to the Company or (ii) a prospective target business with which the Company has entered into a written letter of intent, confidentiality
or other similar agreement or business combination 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 (other than the Company’s independent public accountants) or products sold to the Company or a Target do not reduce
the amount of funds in the Trust Account to below the lesser of (A) $10.20 per Offering Share and (B) the actual 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 including interest earned on the funds held in the Trust Account and not previously released to the Company to pay
its taxes, less taxes payable, except as to any claims by a third party or Target that executed an agreement waiving claims against and
all rights to seek access to the Trust Account whether or not such agreement is enforceable. In the event that any such executed waiver
is deemed to be unenforceable against such third party, the Sponsor shall not be responsible for any liability as a result of any such
third-party claims. Notwithstanding any of the foregoing, such indemnification of the Company by the Sponsor shall not apply as to any
claims under the Company’s obligation to indemnify the Underwriters against certain liabilities, including liabilities under the
Securities Act of 1933, as amended (the “Securities Act”). 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 an additional 3,600,000 Units (as described in
the Prospectus), the Sponsor agrees, upon the expiration or waiver of such option, to forfeit, for cancellation at no cost, a number of
Founder Shares equal to 900,000 multiplied by a fraction, (a) the numerator of which is 3,600,000 minus the number of Units purchased
by the Underwriter upon the exercise of their over-allotment option, and (b) the denominator of which is 3,600,000. The forfeiture
will be adjusted to the extent that the over-allotment option is not exercised in full by the Underwriters so that the Founder Shares
will represent 20.0% of the Company’s issued and outstanding Common Stock after the Public Offering. The Sponsor further agrees
that to the extent that (i) the size of the Public Offering is increased or decreased and (ii) the Sponsor has either purchased
or sold shares of Common Stock or an adjustment to the number of Founder Shares has been effected by way of a stock split, stock dividend,
reverse stock split, contribution back to capital or otherwise, in each case in connection with such increase or decrease in the size
of the Public Offering, then (A) the references to 3,600,000 in the numerator and denominator of the formula in the first sentence
of this paragraph shall be changed to a number equal to 15.0% of the number of Units issued in the Public Offering and (B) the reference
to 900,000 in the formula set forth in the first sentence of this paragraph shall be adjusted to such number of Founder Shares that the
Sponsor would have to collectively return to the Company in order for all holders of Founder Shares to hold an aggregate of 20.0% of the
Company’s issued and outstanding shares of Common Stock after the Public Offering.


 


6.            The
Sponsor and each Insider hereby agree and acknowledge that: (i) each of the Underwriters and the Company would be irreparably injured
in the event of a breach by the Sponsor or an 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 seek 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) Subject
to the exceptions set forth herein, the Sponsor and each Insider agree not to transfer, assign or sell any Founder Shares or the Class A
Common Stock issuable upon conversion of the Founder Shares held by it, him or her until the earlier of (i) one year after the date
of the consummation of a Business Combination and (ii) the earlier to occur of, subsequent to a Business Combination, (A) the
first date on which the last reported sale price of the Class A 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 150 days after the consummation of a Business Combination and (B) the date on which the Company consummates
a subsequent 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 Class A Common Stock for cash, securities or other property (the “Founder
Shares Lock-up Period”).


 






     


     


    

 


(b)            Subject
to the exceptions set forth herein, the Sponsor and each Insider agree not to transfer, assign or sell any Private Placement Warrants
or Class A Common Stock underlying such warrants held by it, him or her, 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 (including the conversions or exchanges
of the Founder Shares to shares of Class B Common Stock or Class F Common Stock, as applicable, and the issuance of Founder
Shares upon the forfeiture by the Sponsor to the Company of an identical number of Founder Shares), Private Placement Warrants and shares
of Class A Common Stock issued or issuable upon the exercise or conversion of the Private Placement Warrants or the Founder Shares
and that are held by the Sponsor, any Insider or any of their permitted transferees (that have complied with this paragraph 7(c))
are permitted (i) to the Company’s officers or directors, any affiliates or family members of any of the Company’s officers
or directors, the Sponsor, any members of the Sponsor or their affiliates, or any affiliates of the Sponsor; (ii) in the case of
an individual, by gift to members of the individual’s immediate family or to a trust, the beneficiary of which is a member of one
of the individual’s immediate family, an affiliate of such person or to a charitable organization; (iii) in the case of an
individual, by virtue of laws of descent and distribution upon death of the individual; (iv) in the case of an individual, pursuant
to a qualified domestic relations order; (v) by virtue of the laws of the state of Delaware or the Sponsor’s operating agreement
upon dissolution of the Sponsor; (vi) 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; (vii) in the event of the Company’s
liquidation prior to the completion of a Business Combination; or (viii) in the event of completion of a liquidation, merger, stock
exchange or other similar transaction which results in all of the Company’s stockholders having the right to exchange their shares
of Class A Common Stock for cash, securities or other property subsequent to the completion of a Business Combination; provided,
however, that in the case of clauses (i) through (vi), these permitted transferees must enter into a written agreement agreeing
to be bound by these transfer restrictions.


 


8.            Each
Insider’s biographical information furnished to the Company and the Underwriters that are included in the Prospectus is true and
accurate in all respects and does not omit any material information with respect to such Insider’s background and contains all of
the information required to be disclosed pursuant to Item 401 of Regulation S-K promulgated under the Securities Act. Each Insider’s
questionnaire furnished to the Company and the Underwriters including any such information that is included in the Prospectus, is true
and accurate in all respects. Each Insider represents and warrants that: such Insider 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; such Insider 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 such Insider is not currently a defendant in any such criminal proceeding; and none of the Sponsor or any such Insider
has ever 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.


 






     


     


    

 


9.            Except
as disclosed in the Prospectus, none of the Sponsor, the Insiders or their respective affiliates shall receive 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). However, such persons may receive the following payments, none of which will be made from the proceeds held
in the Trust Account prior to the completion of the initial Business Combination: repayment of a loan of up to $300,000 made to the Company
by an affiliate of the Sponsor, pursuant to an Amended and Restated Promissory Note dated effective as of March 26, 2021; payment
of an aggregate of $15,000 per month to the Sponsor or an affiliate thereof for office space, utilities and secretarial and administrative
support, pursuant to an Administrative Support Agreement, dated November 16, 2021; reimbursement for any out-of-pocket expenses
related to identifying, investigating, negotiating and consummating an initial Business Combination; and 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 an affiliate of the Sponsor or certain
of the Company’s officers and 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.
Up to $1,500,000 of such loans may be convertible into warrants at a price of $1.00 per warrant at the option of the lender. Such warrants
shall be identical to the Private Placement Warrants, including as to exercise price, exercisability and exercise period. Additionally,
in the event the Company does not consummate its initial Business Combination within 15 months, the Company may, by resolution of the
Board and if requested by the Sponsor, extend the period of time to consummate a business combination up to two times, each by an additional
three months (for a total of up to 21 months to complete an initial business combination), subject to the Sponsor (or its affiliates
or designees) depositing into the Trust Account, on or prior to the applicable deadline, additional funds of $2,400,000, or $2,760,000
if the underwriters’ over-allotment option is exercised in full ($0.10 per unit in either case), for each of the available three-month
extensions, for a total payment of up to $4,800,000, or up to $5,520,000 if the underwriters’ over-allotment option is exercised
in full ($0.20 per unit in either case). Any such payments would be made in the form of non-interest bearing loans. If the Company completes
its initial Business Combination, it will, at the option of the Sponsor, repay such loaned amounts out of the proceeds of the Trust Account
released to the Company or convert a portion or all of the total loan amount into warrants at a price of $1.00 per warrant, which warrants
will be identical to the Private Placement Warrants. If the Company does not complete a business combination, it will repay such loans
only from funds held outside of the Trust Account.


 


10.            The
Sponsor and each Insider has full right and power, without violating any agreement to which it, he or she 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 director of the Company and each Insider hereby consents to being named in the Prospectus
as an officer and/or director of the Company, as applicable.


 


11.            As
used herein, (a) “Business Combination” shall mean a merger, capital stock exchange, asset acquisition,
stock purchase, reorganization or similar business combination, involving the Company and one or more businesses or entities; (b) “Founder
Shares” shall mean (i) the shares of Class F Common Stock held by the Sponsor, the Company’s independent
directors and any other holder prior to the consummation of the Public Offering, (ii) the shares of Class B Common Stock issued
upon the conversion of such Class F Common Stock and (iii) the shares of Class A Common Stock issued upon the conversion
of such Class B Common Stock; (c) “Private Placement Warrants” shall mean the warrants to purchase
12,290,000 shares of Class A Common Stock (or 13,730,000 shares of Class A Common Stock if the Underwriters’ over-allotment
option in connection with the Public Offering is exercised in full), that the purchasers named in Exhibit A to the Private Placement
Warrants Purchase Agreement, dated November 16, 2021, among the Company and such purchasers, have agreed to purchase for an aggregate
purchase price of approximately $12,290,000 (or approximately $13,730,000 if the Underwriters’ over-allotment option in connection
with the Public Offering is exercised in full), or $1.00 per warrant, in a private placement that shall occur simultaneously with the
consummation of the Public Offering; (iv) “Public Stockholders” shall mean the holders of shares of Class A
Common Stock issued in the Public Offering; and (v) “Trust Account” shall mean the trust fund into which
a portion of the net proceeds of the Public Offering and the sale of the Private Placement Warrants shall be deposited.


 


12.            This
Letter Agreement constitutes the entire agreement and understanding of the parties hereto in respect of the subject matter hereof and
supersedes all prior understandings, agreements or representations by or among the parties hereto, written or oral, to the extent they
relate in any way to the subject matter hereof or the transactions contemplated hereby. This Letter Agreement may not be changed, amended,
modified or waived (other than to correct a typographical error) as to any particular provision, except by a written instrument executed
by all parties hereto.


 






     


     


    

 


13.            No
party hereto may assign either this Letter Agreement or any of its rights, interests or obligations hereunder without the prior written
consent of the other parties. Any purported assignment in violation of this paragraph shall be void and ineffectual and shall not operate
to transfer or assign any interest or title to the purported assignee. This Letter Agreement shall be binding on the Sponsor, each Insider
and each of their respective successors, heirs and assigns and permitted transferees.


 


14.            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 invalid
or unenforceable term or provision, the parties hereto intend that there shall be added as a part of this Letter Agreement a provision
as similar in terms to such invalid or unenforceable provision as may be possible and be valid and enforceable.


 


15.            This
Letter 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. The parties
hereto (i) all agree that any action, proceeding, claim or dispute arising out of, or relating in any way to, this Letter Agreement
shall be brought and enforced in the courts of New York City, in the State of New York, and irrevocably submit to such jurisdiction and
venue, which jurisdiction and venue shall be exclusive and (ii) waive any objection to such exclusive jurisdiction and venue or that
such courts represent an inconvenient forum.


 


16.            Any
notice, consent or request to be given in connection with any of the terms or provisions of this Letter Agreement shall be in writing
and shall be sent by express mail or similar private courier service, by certified mail (return receipt requested), by hand delivery or
facsimile or other electronic transmission.


 


17.            This
Letter Agreement shall terminate on the earlier of (i) the expiration of the Lock-up Periods or (ii) the liquidation of the
Company; provided, however, that this Letter Agreement shall earlier terminate in the event that the Public Offering is not
consummated and closed by February 14, 2022, provided further that paragraph 4 of this Letter Agreement shall survive
such liquidation.


 


18.            This
Letter Agreement may be executed in any number of original or facsimile counterparts and each of such counterparts shall for all purposes
be deemed to be an original, and all such counterparts shall together constitute but one and the same instrument. Delivery of a signed
counterpart of this Agreement by facsimile or electronic transmission shall constitute valid and sufficient delivery thereof.
