2. REGISTRATION RIGHTS.

 

2.1 Demand Registration.

 

2.1.1 Request for Registration.
At any time and from time to time on or after (i) the date that the Company consummates a Business Combination with respect to the Private
Units (or underlying shares of Common Stock), Over-Allotment Units (or underlying shares of Common Stock) and Loan Securities or (ii)
three (3) months prior to the Release Date with respect to all other Registrable Securities, the holders of a majority-in-interest of
the Registrable Securities, as the case may be, held by the Investors, officers or directors of the Company or their affiliates, or the
transferees of the Investors, may make a written demand, on no more than two (2) occasions, for registration under the Securities Act
of all or part of their Registrable Securities, as the case may be (a “Demand Registration” ). Any demand for a Demand Registration
shall specify the number of shares of Registrable Securities proposed to be sold and the intended method(s) of distribution thereof. The
Company will notify all holders of Registrable Securities of the demand, and each holder of Registrable Securities who wishes to include
all or a portion of such holder’s Registrable Securities in the Demand Registration (each such holder including shares of Registrable
Securities in such registration, a “Demanding Holder”) shall so notify the Company within fifteen (15) days after the receipt
by the holder of the notice from the Company. Upon any such request, the Demanding Holders shall be entitled to have their Registrable
Securities included in the Demand Registration, subject to Section 2.1.4 and the provisos set forth in Section 3.1.1. The
Company shall not be obligated to effect more than an aggregate of two (2) Demand Registration under this Section 2.1.1 in respect
of all Registrable Securities.

 

2.1.2 Effective Registration.
A registration will not count as a Demand Registration until the Registration Statement filed with the Commission with respect to such
Demand Registration has been declared effective and the Company has complied with all of its obligations under this Agreement with respect
thereto; provided, however, that if, after such Registration Statement has been declared effective, the offering of Registrable Securities
pursuant to a Demand Registration is interfered with by any stop order or injunction of the Commission or any other governmental agency
or court, the Registration Statement with respect to such Demand Registration will be deemed not to have been declared effective, unless
and until, (i) such stop order or injunction is removed, rescinded or otherwise terminated, and (ii) a majority-in-interest of the Demanding
Holders thereafter elect to continue the offering; provided, further, that the Company shall not be obligated to file a second Registration
Statement until a Registration Statement that has been filed is counted as a Demand Registration or is terminated.

 

    3

     

    

 

2.1.3 Underwritten Offering. If
a majority-in-interest of the Demanding Holders so elect and such holders so advise the Company as part of their written demand for a
Demand Registration, the offering of such Registrable Securities pursuant to such Demand Registration shall be in the form of an underwritten
offering. In such event, the right of any holder to include its Registrable Securities in such registration shall be conditioned upon
such holder’s participation in such underwriting and the inclusion of such holder’s Registrable Securities in the underwriting
to the extent provided herein. All Demanding Holders proposing to distribute their Registrable Securities through such underwriting shall
enter into an underwriting agreement in customary form with the Underwriter or Underwriters selected for such underwriting by a majority-in-interest
of the holders initiating the Demand Registration.

 

2.1.4 Reduction of Offering. If
the managing Underwriter or Underwriters for a Demand Registration that is to be an underwritten offering advises the Company and the
Demanding Holders in writing that the dollar amount or number of shares of Registrable Securities which the Demanding Holders desire to
sell, taken together with all other shares of Common Stock or other securities which the Company desires to sell and the shares of Common
Stock, if any, as to which registration has been requested pursuant to written contractual piggy-back registration rights held by other
stockholders of the Company who desire to sell, exceeds the maximum dollar amount or maximum number of shares that can be sold in such
offering without adversely affecting the proposed offering price, the timing, the distribution method, or the probability of success of
such offering (such maximum dollar amount or maximum number of shares, as applicable, the “Maximum Number of Shares” ), then
the Company shall include in such registration: (i) first, the Registrable Securities as to which Demand Registration has been requested
by the Demanding Holders (pro rata in accordance with the number of shares that each such Person has requested be included in such registration,
regardless of the number of shares held by each such Person (such proportion is referred to herein as “Pro Rata” )) that can
be sold without exceeding the Maximum Number of Shares; (ii) second, to the extent that the Maximum Number of Shares has not been reached
under the foregoing clause (i), the shares of Common Stock or other securities that the Company desires to sell that can be sold without
exceeding the Maximum Number of Shares; and (iii) third, to the extent that the Maximum Number of Shares has not been reached under the
foregoing clauses (i) and (ii), the shares of Common Stock or other securities for the account of other persons that the Company is obligated
to register pursuant to written contractual arrangements with such persons and that can be sold without exceeding the Maximum Number of
Shares.

 

2.1.5 Withdrawal. If a majority-in-interest
of the Demanding Holders disapprove of the terms of any underwriting or are not entitled to include all of their Registrable Securities
in any offering, such majority-in-interest of the Demanding Holders may elect to withdraw from such offering by giving written notice
to the Company and the Underwriter or Underwriters of their request to withdraw prior to the effectiveness of the Registration Statement
filed with the Commission with respect to such Demand Registration. If the majority-in-interest of the Demanding Holders withdraws from
a proposed offering relating to a Demand Registration, then such registration shall not count as a Demand Registration provided for in
Section 2.1.

 

    4

     

    

 

2.2 Piggy-Back Registration.

 

2.2.1 Piggy-Back Rights. If at
any time on or after the date the Company consummates a Business Combination the Company proposes to file a Registration Statement under
the Securities Act with respect to an offering of equity securities, or securities or other obligations exercisable or exchangeable for,
or convertible into, equity securities, by the Company for its own account or for stockholders of the Company for their account (or by
the Company and by stockholders of the Company including, without limitation, pursuant to Section 2.1), other than a Registration
Statement (i) filed in connection with any employee stock option or other benefit plan, (ii) for an exchange offer or offering of securities
solely to the Company’s existing stockholders, (iii) for an offering of debt that is convertible into equity securities of the Company
or (iv) for a dividend reinvestment plan, then the Company shall (x) give written notice of such proposed filing to the holders of Registrable
Securities as soon as practicable but in no event less than ten (10) days before the anticipated filing date, which notice shall describe
the amount and type of securities to be included in such offering, the intended method(s) of distribution, and the name of the proposed
managing Underwriter or Underwriters, if any, of the offering, and (y) offer to the holders of Registrable Securities in such notice the
opportunity to register the sale of such number of shares of Registrable Securities as such holders may request in writing within five
(5) days following receipt of such notice (a “Piggy-Back Registration” ). Subject to Section 2.2.2, the Company shall
cause such Registrable Securities to be included in such registration and shall use its reasonable best efforts to cause the managing
Underwriter or Underwriters of a proposed underwritten offering to permit the Registrable Securities requested to be included in a Piggy-Back
Registration on the same terms and conditions as any similar securities of the Company and to permit the sale or other disposition of
such Registrable Securities in accordance with the intended method(s) of distribution thereof. All holders of Registrable Securities proposing
to distribute their securities through a Piggy-Back Registration that involves an Underwriter or Underwriters shall enter into an underwriting
agreement in customary form with the Underwriter or Underwriters selected for such Piggy-Back Registration. Notwithstanding the provisions
set forth in the immediately preceding sentences, the right to a Piggy-Back Registration set forth under this Section 2.2.1 with
respect to the Registrable Securities shall terminate on the seventh anniversary of the Effective Date.

 

2.2.2 Reduction of Offering. If
the managing Underwriter or Underwriters for a Piggy-Back Registration that is to be an underwritten offering advises the Company and
the holders of Registrable Securities in writing that the dollar amount or number of shares of Common Stock which the Company desires
to sell, taken together with the shares of Common Stock, if any, as to which registration has been demanded pursuant to written contractual
arrangements with persons other than the holders of Registrable Securities hereunder, the Registrable Securities as to which registration
has been requested under this Section 2.2, and the shares of Common Stock, if any, as to which registration has been requested
pursuant to the written contractual piggy-back registration rights of other stockholders of the Company, exceeds the Maximum Number of
Shares, then the Company shall include in any such registration:

 

a) If the registration is undertaken for
the Company’s account: (A) first, the shares of Common Stock or other securities that the Company desires to sell that can be sold
without exceeding the Maximum Number of Shares; (B) second, to the extent that the Maximum Number of Shares has not been reached under
the foregoing clause (A), the shares of Common Stock or other securities, if any, comprised of Registrable Securities, as to which registration
has been requested pursuant to the applicable written contractual piggy-back registration rights of such security holders, Pro Rata, that
can be sold without exceeding the Maximum Number of Shares; and (C) third, to the extent that the Maximum Number of Shares has not been
reached under the foregoing clauses (A) and (B), the shares of Common Stock or other securities for the account of other persons that
the Company is obligated to register pursuant to written contractual piggy-back registration rights with such persons and that can be
sold without exceeding the Maximum Number of Shares;

 

    5

     

    

 

b) If the registration is a “demand”
registration undertaken at the demand of persons other than either the holders of Registrable Securities, (A) first, the shares of Common
Stock or other securities for the account of the demanding persons that can be sold without exceeding the Maximum Number of Shares; (B)
second, to the extent that the Maximum Number of Shares has not been reached under the foregoing clause (A), the shares of Common Stock
or other securities that the Company desires to sell that can be sold without exceeding the Maximum Number of Shares; (C) third, to the
extent that the Maximum Number of Shares has not been reached under the foregoing clauses (A) and (B), collectively the shares of Common
Stock or other securities comprised of Registrable Securities, Pro Rata, as to which registration has been requested pursuant to the terms
hereof, that can be sold without exceeding the Maximum Number of Shares; and (D) fourth, to the extent that the Maximum Number of Shares
has not been reached under the foregoing clauses (A), (B) and (C), the shares of Common Stock or other securities for the account of other
persons that the Company is obligated to register pursuant to written contractual arrangements with such persons, that can be sold without
exceeding the Maximum Number of Shares.

 

2.2.3 Withdrawal. Any holder of
Registrable Securities may elect to withdraw such holder’s request for inclusion of Registrable Securities in any Piggy-Back Registration
by giving written notice to the Company of such request to withdraw prior to the effectiveness of the Registration Statement. The Company
(whether on its own determination or as the result of a withdrawal by persons making a demand pursuant to written contractual obligations)
may withdraw a Registration Statement at any time prior to the effectiveness of such Registration Statement. Notwithstanding any such
withdrawal, the Company shall pay all expenses incurred by the holders of Registrable Securities in connection with such Piggy-Back Registration
as provided in Section 3.3.

 

2.2.4 Registrations on Form S-3.
The holders of Registrable Securities may at any time and from time to time, request in writing that the Company register the resale of
any or all of such Registrable Securities on Form S-3 or any similar short-form registration which may be available at such time (“Form
S-3”); provided, however, that (i) the Company shall not be obligated to effect such request through an underwritten offering and
(ii) the Company shall not be obligated to effect more than two (2) such requests. Upon receipt of such written request, the Company will
promptly give written notice of the proposed registration to all other holders of Registrable Securities, and, as soon as practicable
thereafter, effect the registration of all or such portion of such holder’s or holders’ Registrable Securities as are specified
in such request, together with all or such portion of the Registrable Securities or other securities of the Company, if any, of any other
holder or holders joining in such request as are specified in a written request given within fifteen (15) days after receipt of such written
notice from the Company; provided, however, that the Company shall not be obligated to effect any such registration pursuant
to this Section 2.2.4: (i) if Form S-3 is not available for such offering; or (ii) if the holders of the Registrable Securities,
together with the holders of any other securities of the Company entitled to inclusion in such registration, propose to sell Registrable
Securities and such other securities (if any) at any aggregate price to the public of less than $500,000. Registrations effected pursuant
to this Section 2.2.4 shall not be counted as Demand Registrations effected pursuant to Section 2.1.

 

2.3 Limitations on Registration
Rights. Notwithstanding anything herein to the contrary, (i) Chardan Capital Markets, LLC (“Chardan”) or any affiliates
or designees of Chardan may not exercise their rights under Sections 2.1 and 2.2 hereunder after five (5) and seven (7)
years after the effective date of the commencement of sales of the Company’s initial public offering, respectively, and (ii) Chardan
or any affiliates or designees of Chardan may not exercise their rights under Section 2.1 more than one time.

is required to effect the registration of any Registrable Securities pursuant to Section 2, the Company shall use its reasonable

thereof as expeditiously as practicable, and in connection with any such request:

 

3.1.1 Filing Registration Statement.
The Company shall use its reasonable best efforts to, as expeditiously as possible after receipt of a request for a Demand Registration

to cause such Registration Statement to become effective and use its reasonable best efforts to keep it effective for the period required
by Section 3.1.3; provided, however, that the Company shall have the right to defer any Demand Registration for up
to thirty (30) days, and any Piggy-Back Registration for such period as may be applicable to deferment of any demand registration to which
such Piggy-Back Registration relates, in each case if the Company shall furnish to the holders a certificate signed by Chief Executive
Officer or Chairman of the Company stating that, in the good faith judgment of the Board of Directors of the Company, it would be materially
detrimental to the Company and its stockholders for such Registration Statement to be effected at such time; provided further, however,
that the Company shall not have the right to exercise the right set forth in this provision more than once in any 365-day period in respect
of a Demand Registration hereunder.

therein or necessary to make the statements therein not misleading, and promptly make available to the holders of Registrable Securities
included in such Registration Statement any such supplement or amendment; except that before filing with the Commission a Registration
Statement or prospectus or any amendment or supplement thereto, including documents incorporated by reference, the Company shall furnish
to the holders of Registrable Securities included in such Registration Statement and to the legal counsel for any such holders, copies

under such securities or “blue sky” laws of such jurisdictions in the United States as the holders of Registrable Securities
included in such Registration Statement (in light of their intended plan of distribution) may request and (ii) take such action necessary
to cause such Registrable Securities covered by the Registration Statement to be registered with or approved by such other governmental

officers, employees, affiliates, directors, partners, members, attorneys and agents, and each person, if any, who controls an Investor
and each other holder of Registrable Securities (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange
Act) (each, an “Investor Indemnified Party” ), from and against any expenses, losses, judgments, claims, damages or liabilities,
whether joint or several, arising out of or based upon any untrue statement (or allegedly untrue statement) of a material fact contained
in any Registration Statement under which the sale of such Registrable Securities was registered under the Securities Act, any preliminary
prospectus, final prospectus or summary prospectus contained in the Registration Statement, or any amendment or supplement to such Registration
Statement, or arising out of or based upon any omission (or alleged omission) to state a material fact required to be stated therein or
necessary to make the statements therein not misleading, or any violation by the Company of the Securities Act or any rule or regulation
promulgated thereunder applicable to the Company and relating to action or inaction required of the Company in connection with any such
registration; and the Company shall promptly reimburse the Investor Indemnified Party for any legal and any other expenses reasonably
incurred by such Investor Indemnified Party in connection with investigating and defending any such expense, loss, judgment, claim, damage,
liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such expense, loss,
claim, damage or liability arises out of or is based upon any untrue statement or allegedly untrue statement or omission or alleged omission
made in such Registration Statement, preliminary prospectus, final prospectus, or summary prospectus, or any such amendment or supplement,
in reliance upon and in conformity with information furnished to the Company, in writing, by such selling holder expressly for use therein.
The Company also shall indemnify any Underwriter of the Registrable Securities, their officers, affiliates, directors, partners, members
and agents and each person who controls such Underwriter on substantially the same basis as that of the indemnification provided above
in this Section 4.1.

 

4.2 Indemnification by Holders of Registrable
Securities. Each selling holder of Registrable Securities will, in the event that any registration is being effected under the Securities
Act pursuant to this Agreement of any Registrable Securities held by such selling holder, indemnify and hold harmless the Company, each
of its directors and officers and each Underwriter (if any), and each other selling holder and each other person, if any, who controls
another selling holder or such Underwriter within the meaning of the Securities Act, against any losses, claims, judgments, damages or
liabilities, whether joint or several, insofar as such losses, claims, judgments, damages or liabilities (or actions in respect thereof)
arise out of or are based upon any untrue statement or allegedly untrue statement of a material fact contained in any Registration Statement
under which the sale of such Registrable Securities was registered under the Securities Act, any preliminary prospectus, final prospectus
or summary prospectus contained in the Registration Statement, or any amendment or supplement to the Registration Statement, or arise
out of or are based upon any omission or the alleged omission to state a material fact required to be stated therein or necessary to make
the statement therein not misleading, if the statement or omission was made in reliance upon and in conformity with information furnished
in writing to the Company by such selling holder expressly for use therein, and shall reimburse the Company, its directors and officers,
and each other selling holder or controlling person for any legal or other expenses reasonably incurred by any of them in connection with
investigation or defending any such loss, claim, damage, liability or action. Each selling holder’s indemnification obligations
hereunder shall be several and not joint and shall be limited to the amount of any net proceeds actually received by such selling holder.

4.3 Conduct of Indemnification Proceedings.
Promptly after receipt by any person of any notice of any loss, claim, damage or liability or any action in respect of which indemnity
may be sought pursuant to Section 4.1 or 4.2, such person (the “Indemnified Party”) shall, if a claim in respect
thereof is to be made against any other person for indemnification hereunder, notify such other person (the “Indemnifying Party”
) in writing of the loss, claim, judgment, damage, liability or action; provided, however, that the failure by the Indemnified Party to
notify the Indemnifying Party shall not relieve the Indemnifying Party from any liability which the Indemnifying Party may have to such
Indemnified Party hereunder, except and solely to the extent the Indemnifying Party is actually prejudiced by such failure. If the Indemnified
Party is seeking indemnification with respect to any claim or action brought against the Indemnified Party, then the Indemnifying Party
shall be entitled to participate in such claim or action, and, to the extent that it wishes, jointly with all other Indemnifying Parties,
to assume control of the defense thereof with counsel satisfactory to the Indemnified Party. After notice from the Indemnifying Party
to the Indemnified Party of its election to assume control of the defense of such claim or action, the Indemnifying Party shall not be
liable to the Indemnified Party for any legal or other expenses subsequently incurred by the Indemnified Party in connection with the
defense thereof other than reasonable costs of investigation; provided, however, that in any action in which both the Indemnified Party
and the Indemnifying Party are named as defendants, the Indemnified Party shall have the right to employ separate counsel (but no more
than one such separate counsel) to represent the Indemnified Party and its controlling persons who may be subject to liability arising
out of any claim in respect of which indemnity may be sought by the Indemnified Party against the Indemnifying Party, with the fees and
expenses of such counsel to be paid by such Indemnifying Party if, based upon the written opinion of counsel of such Indemnified Party,
representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them.
No Indemnifying Party shall, without the prior written consent of the Indemnified Party, consent to entry of judgment or effect any settlement
of any claim or pending or threatened proceeding in respect of which the Indemnified Party is or could have been a party and indemnity
could have been sought hereunder by such Indemnified Party, unless such judgment or settlement includes an unconditional release of such
Indemnified Party from all liability arising out of such claim or proceeding.

 

4.4 Contribution.

 

4.4.1 If the indemnification provided
for in the foregoing Sections 4.1, 4.2 and 4.3 is unavailable to any Indemnified Party in respect of any loss, claim,
damage, liability or action referred to herein, then each such Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall
contribute to the amount paid or payable by such Indemnified Party as a result of such loss, claim, damage, liability or action in such
proportion as is appropriate to reflect the relative fault of the Indemnified Parties and the Indemnifying Parties in connection with
the actions or omissions which resulted in such loss, claim, damage, liability or action, as well as any other relevant equitable considerations.
The relative fault of any Indemnified Party and any Indemnifying Party shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information
supplied by such Indemnified Party or such Indemnifying Party and the parties’ relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission.

 

4.4.2 The parties hereto agree that it
would not be just and equitable if contribution pursuant to this Section 4.4 were determined by pro rata allocation or by any other
method of allocation which does not take account of the equitable considerations referred to in the immediately preceding Section 4.4.1.

 

4.4.3 The amount paid or payable by an
Indemnified Party as a result of any loss, claim, damage, liability or action referred to in the immediately preceding paragraph shall
be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Party in connection
with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 4.4, no holder of Registrable
Securities shall be required to contribute any amount in excess of the dollar amount of the net proceeds (after payment of any underwriting
fees, discounts, commissions or taxes) actually received by such holder from the sale of Registrable Securities which gave rise to such
contribution obligation. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities
Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

 

    12

     

    

 

5. RULE 144.

 

5.1 Rule 144. The Company covenants that
it shall file any reports required to be filed by it under the Securities Act and the Exchange Act and shall take such further action
as the holders of Registrable Securities may reasonably request, all to the extent required from time to time to enable such holders to
sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by Rule 144
under the Securities Act, as such Rules may be amended from time to time, or any similar rule or regulation hereafter adopted by the Commission.

 

6. MISCELLANEOUS.

 

6.1 Other Registration Rights. The Company
represents and warrants that, except as disclosed in the Company’s registration statement on Form S-1 (File No. 333-261467), no
person, other than the holders of the Registrable Securities, has any right to require the Company to register any of the Company’s
share capital for sale or to include the Company’s share capital in any registration filed by the Company for the sale of share
capital for its own account or for the account of any other person.

 

6.2 Assignment; No Third Party Beneficiaries.
This Agreement and the rights, duties and obligations of the Company hereunder may not be assigned or delegated by the Company in whole
or in part. This Agreement and the rights, duties and obligations of the holders of Registrable Securities hereunder may be freely assigned
or delegated by such holder of Registrable Securities in conjunction with and to the extent of any transfer of Registrable Securities
by any such holder. This Agreement and the provisions hereof shall be binding upon and shall inure to the benefit of each of the parties,
to the permitted assigns of the Investors or holder of Registrable Securities or of any assignee of the Investors or holder of Registrable
Securities. This Agreement is not intended to confer any rights or benefits on any persons that are not party hereto other than as expressly
set forth in Section 4 and this Section 6.2.

 

6.3 Notices. All notices, demands, requests,
consents, approvals or other communications (collectively, “Notices” ) required or permitted to be given hereunder or which
are given with respect to this Agreement shall be in writing and shall be personally served, delivered by reputable air courier service
with charges prepaid, or transmitted by hand delivery, telegram, telex or facsimile, addressed as set forth below, or to such other address
as such party shall have specified most recently by written notice. Notice shall be deemed given on the date of service or transmission
if personally served or transmitted by telegram, telex or facsimile; provided, that if such service or transmission is not on a business
day or is after normal business hours, then such notice shall be deemed given on the next business day. Notice otherwise sent as provided
herein shall be deemed given on the next business day following timely delivery of such notice to a reputable air courier service with
an order for next-day delivery.

	 	Re:	Administrative
    Services Agreement

 

Ladies
and Gentlemen:

 

This
letter agreement, by and between Welsbach Technology Metals Acquisition Corp. (the “Company”) and Welsbach Acquisition Holdings
LLC (the “Sponsor”), dated as of the date hereof, will confirm our agreement that, commencing on the date the securities
of the Company are first listed on the Nasdaq Global Market (the “Listing Date”), pursuant to a Registration Statement on
Form S-1 and prospectus filed with the U.S. Securities and Exchange Commission (the “Registration Statement”) and continuing
until the earlier of the consummation by the Company of an initial business combination or the Company’s liquidation (in each case
as described in the Registration Statement) (such earlier date hereinafter referred to as the “Termination Date”):

 

(i)
The Sponsor shall make available, or cause to be made available, to the Company, certain office space, utilities and secretarial and
administrative support as may be reasonably required by the Company. In exchange therefor, the Company shall pay the Sponsor a sum of
$10,000 per month on the Listing Date and continuing monthly thereafter until the Termination Date; and

 

(ii)
The Sponsor hereby irrevocably waives any and all right, title, interest, causes of action and claims of any kind as a result of, or
arising out of, this letter agreement (each, a “Claim”) in or to, and any and all right to seek payment of any amounts due
to it out of, the trust account established for the benefit of the public stockholders of the Company and into which substantially all
of the proceeds of the Company’s initial public offering will be deposited (the “Trust Account”) as a result of, or
arising out of, this letter agreement, and hereby irrevocably waives any Claim it may have in the future, which Claim would reduce, encumber
or otherwise adversely affect the Trust Account or any monies or other assets in the Trust Account, and further agrees not to seek recourse,
reimbursement, payment or satisfaction of any Claim against the Trust Account or any monies or other assets in the Trust Account for
any reason whatsoever.

 

This
letter agreement constitutes the entire agreement and understanding of the parties hereto in respect of its subject matter 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 amended, modified or waived as to any particular provision, except by a written instrument executed by the
parties hereto.

 

No
party hereto may assign either this letter agreement or any of its rights, interests, or obligations hereunder without the prior written
approval of the other party. 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 constitutes the entire relationship of the parties hereto, and any litigation between the parties (whether grounded
in contract, tort, statute, law or equity) shall be governed by, construed in accordance with, and interpreted pursuant to the laws of
the State of New York, without giving effect to its choice of law principles.
