**Item 1.01 Entry into a Material Definitive Agreement.**

<u>Entry into Non-Redemption Agreements</u>

On June 6, 2025, Welsbach Technology Metals Acquisition Corp. ("WTMA") filed a definitive proxy statement on Schedule 14A for the purposes of calling a special meeting of WTMA's stockholders (the "Special Meeting") to approve, among other proposals, an amendment to WTMA's amended and restated certificate of incorporation to extend the date by which it has to consummate an initial business combination from June 30, 2025 to September 30, 2025 (the "Extension").

On June 20, 2025 and June 23, 2025, in connection with the Special Meeting, WTMA and Welsbach Acquisition Holdings LLC (the "Sponsor") entered into non-redemption agreements ("Non-Redemption Agreements") with several unaffiliated third-party holders of WTMA's common stock (the "Investors") on substantially the same terms in exchange for their agreement to not redeem up to an aggregate of 465,880 shares of the WTMA's common stock (the "Non-Redeemed Shares") in connection with the Special Meeting. In exchange for the foregoing commitment not to redeem such shares, the Sponsor and WTMA have agreed to cause the surviving entity ("MergeCo") of any future WTMA initial business combination to issue to the Investors up to an aggregate of 23,294 ordinary shares of MergeCo immediately following the consummation of an initial business combination if the Investors continue to hold such Non-Redeemed Shares through the Special Meeting.

The Non-Redemption Agreements shall terminate on the earlier of (i) the failure of WTMA's stockholders to approve the Extension at the Special Meeting, (ii) WTMA's determination not to proceed with the Extension, (iii) the fulfillment of all obligations of parties to the Non-Redemption Agreements, (iv) the liquidation or dissolution of WTMA, (v) the mutual written agreement of the parties or (vi) if the applicable Investor exercises its redemption rights with respect to any Non-Redeemed Shares in connection with the Special Meeting and such Non-Redeemed Shares are actually redeemed.

The foregoing summary of the Non-Redemption Agreements does not purport to be complete and is qualified in its entirety by reference to the form of Non-Redemption Agreement attached hereto as Exhibit 10.1, which is incorporated herein by reference.

**Item 3.02 Unregistered Sales of Equity Securities.**

The information disclosed in Item 1.01 of this Current Report on Form 8-K is incorporated by reference into this Item 3.02. The shares of WTMA common stock being offered to Investors pursuant to the Non-Redemption Agreements will be issued pursuant to one or more exemptions under Rule 4(a)(2) or Regulation D under the Securities Act of 1933 based on representations made by the Investors in the Non-Redemption Agreements.

**BEFORE MAKING ANY VOTING DECISION, INVESTORS AND SECURITY HOLDERS OF WTMA ARE URGED TO READ THE PROXY STATEMENT AND ALL OTHER RELEVANT DOCUMENTS FILED OR THAT WILL BE FILED WITH THE SEC IN CONNECTION WITH THE EXTENSION AMENDMENT PROPOSAL BECAUSE THEY WILL CONTAIN IMPORTANT INFORMATION ABOUT THE EXTENSION AMENDMENT PROPOSAL.**

**Exhibit 10.1**

**NON-REDEMPTION AGREEMENT**

This Non-Redemption Agreement (this "<u>Agreement</u>") is entered as of [●], 2025 by and among Welsbach Technology Metals Acquisition Corp. ("<u>WTMA</u>"), Welsbach Acquisition Holdings LLC, a Delaware limited liability company (the "<u>Sponsor</u>") and the undersigned investors (collectively, the "<u>Investor</u>").

**RECITALS**

**WHEREAS**, the Sponsor currently holds WTMA ordinary shares, par value $0.0001 per share, initially purchased in a private placement prior to WTMA's initial public offering (the "<u>Founder Shares</u>");

**WHEREAS**, WTMA expects to hold an extraordinary general meeting of shareholders (the "<u>Meeting</u>") for the purpose of approving, among other things, an amendment to WTMA's Certificate of Incorporation (the "<u>Charter</u>") to extend the date by which WTMA must consummate an initial business combination (the "<u>Initial Business Combination</u>") by three additional months until September 30, 2025 (the "<u>Extension</u>");

**WHEREAS**, the Charter provides that a shareholder of WTMA may redeem its ordinary shares, par value $0.0001 per share, initially sold as part of the units in WTMA's initial public offering (whether they were purchased in WTMA's initial public offering or thereafter in the open market) (the "<u>Public Shares</u>" and together with the Founder Shares, the "<u>Ordinary Shares</u>") in connection with the Charter amendment, on the terms set forth in the Charter ("<u>Redemption Rights</u>");

**WHEREAS**, during the period of the Extension the Sponsor intends to cause WTMA to consummate a business combination, with the target company and business combination structure to be identified, resulting in a surviving operating company being listed on Nasdaq immediately following the Initial Business Combination (such surviving company, "<u>MergeCo</u>"), with the effect that the Ordinary Shares will either be exchanged for or converted into ordinary or common shares of MergeCo (the "<u>MergeCo Shares</u>") with such MergeCo Shares to be issued to the existing shareholders of the WTMA's target, at a valuation that is yet to be determined;

**WHEREAS**, subject to the terms and conditions of this Agreement, the Sponsor desires to cause MergeCo to issue to Investor, and Investor desires to acquire from MergeCo on such basis, that number of MergeCo Shares set forth opposite such Investor's name on <u>Exhibit A</u> (the "<u>Promised Securities</u>"), to be issued to Investor by MergeCo in connection with WTMA's completion of its Initial Business Combination.

**NOW THEREFORE**, in consideration of the mutual covenants and agreements set forth herein and for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Investor and the Sponsor hereby agree as follows:

1. <u>Terms of Transfer</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.1. Upon the terms and subject to the conditions of this Agreement, if (a) as of 5:30 PM, New York time, on
the date of the Meeting, Investor holds the Investor Shares (as defined below), (b) Investor does not exercise (or exercised and validly
rescinds) its Redemption Rights with respect to such Investor Shares in connection with the Meeting, (c) the Extension is approved at
the Meeting and, and (d) the Company implements the Extension, then WTMA and the Sponsor hereby agree to cause MergeCo to issue to Investor
for no additional consideration the Promised Securities set forth on <u>Exhibit A</u>. "Investor Shares" shall mean an amount
of the Public Shares presently held by Investor equal to the lesser of an aggregate amount of (i) [ ] Public Shares, and (ii) 9.9% of
the Public Shares that are not to be redeemed, including those Public Shares subject to non-redemption agreements with other WTMA shareholders
similar to this Agreement on or about the date of the Meeting. The Sponsor and WTMA agree to provide Investor with the final number of
Investor Shares subject to this Agreement no later than 9:30 a.m. Eastern on the first business day before the date of the Meeting (and
in all cases a sufficient amount of time to allow the Investor to reverse any exercise of Redemption Rights with regard to any Investor
Shares), *provided*, that such amount shall not exceed [ ] Public Shares.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.2. WTMA, the Sponsor and Investor hereby agree that the issue by MergeCo of the Promised Securities shall
be subject to the conditions that (i) the Initial Business Combination is consummated; and (ii) Investor [(or its Permitted Transferees
(as such term is defined in section 4.3 of that certain stock escrow agreement, dated December 27, 2021, by and among WTMA, the Sponsor,
WTMA's officers, directors and other insiders and Continental Stock Transfer & Trust Company, as escrow agent (as it exists
on the date hereof, the " <u>Escrow Agreement</u> ")] executes the Joinder (as defined in Section 1.8).

Upon the satisfaction of the foregoing conditions, as applicable, WTMA and the Sponsor shall cause MergeCo to promptly issue (and no later than two (2) business days following the closing of the Initial Business Combination) the Promised Securities to Investor (or its Permitted Transferees) free and clear of any liens or other encumbrances, other than restrictions on transfer imposed by the securities laws. The Sponsor and WTMA covenant and agree to cause MergeCo to facilitate such transfer to Investor (or its Permitted Transferees) in accordance with the foregoing.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.3. <u>Adjustment to Share Amounts</u>. If at any time the number of outstanding Ordinary Shares are increased
or decreased by a consolidation, combination, subdivision or reclassification of the Ordinary Shares of WTMA or other similar event, then,
as of the effective date of such consolidation, combination, subdivision, reclassification or similar event, all share numbers referenced
in this Agreement shall be adjusted in proportion to such increase or decrease in the Ordinary Shares of WTMA. For the avoidance of doubt,
the issuance of MergeCo Shares to the existing shareholders of WTMA's target in connection with the Initial Business Combination
shall not cause any such adjustment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.4. <u>Merger or Reorganization, etc</u>. If there shall occur any reorganization, recapitalization, reclassification,
consolidation or merger involving WTMA in which its Ordinary Shares are converted into or exchanged for securities, cash or other property,
then, following any such reorganization, recapitalization, reclassification, consolidation or merger, in lieu of ordinary shares of WTMA,
the Sponsor shall transfer, with respect to each MergeCo Share to be issued hereunder, the kind and amount of securities, cash or other
property into which such Promised Securities converted or exchanged.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.5. <u>Forfeitures, Transfers, etc.</u> Investor shall not be subject to forfeiture, surrender, claw-back,
transfers, disposals, exchanges or earn-outs for any reason on the Promised Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.6. <u>Delivery of Shares; Other Documents.</u> At the time of the issue of Promised Securities hereunder,
WTMA and the Sponsor shall cause MergeCo to deliver the Promised Securities to Investor in book-entry form effected through MergeCo's
register of members (or other equivalent register) and through WTMA's transfer agent. The parties to this Agreement agree to execute,
acknowledge and deliver such further instruments and to do all such other acts, as may be necessary or appropriate to carry out the purposes
and intent of this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.7. <u>Registration Rights</u>. In connection with the issuance of the Promised Securities, Investor shall
be entitled to registration rights set forth in that certain Registration Rights Agreement, dated December 27, 2021, by and among WTMA,
WTMA's officers, directors and insiders and the Sponsor (as it exists on the date of the Agreement, the " <u>Registration Rights Agreement</u> "), and MergeCo and Investor shall execute the Joinder (as defined below).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.8. <u>Joinder to Agreements</u>. In connection with the issue of the Promised Securities to Investor, Investor
shall execute a joinder to the Registration Rights Agreement and a signature page to the amended and restated version of the Registration
Rights Agreement attached as Annex G to the definitive proxy statement/prospectus filed as part of WTMA's registration statement
on Form S-4 (Registration No. 333-283119), in substantially the forms attached here to as <u>Exhibit B</u> (collectively, the " <u>Joinder</u> ")
pursuant to which Investor shall agree with MergeCo to be bound by the terms and provisions of the Registration Rights Agreement as a
"holder" thereunder with respect to the Promised Securities (upon acquisition thereof) as "Registrable Securities"
thereunder. [Notwithstanding anything in this Agreement and/or the Joinder to the contrary, Investor shall not be subject to any transfer
or lock-up restrictions under the Registration Rights Agreement or any other agreement (other than transfer restrictions that apply to
the MergeCo Shares generally under applicable securities laws).]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.9. <u>Termination</u>. This Agreement and each of the obligations of the undersigned shall terminate on earlier
of (a) the failure of WTMA's shareholders to approve the Extension at the Meeting, (b) WTMA's abandonment of the Extension
prior to the implementation thereof, (c) the fulfillment of all obligations of parties hereto, (d) the liquidation or dissolution of WTMA
prior to completing a Business Combination, (e) the mutual written agreement of the parties hereto; or (f) if Investor exercises its Redemption
Rights with respect to any Investor Shares in connection with the Meeting and such Investors Shares are actually redeemed in connection
with the Meeting. Notwithstanding any provision in this Agreement to the contrary, the Sponsor's obligation to cause MergeCo to
issue the Promised Securities to Investor shall be conditioned on (i) the satisfaction of the conditions set forth in Section 1.2 and
(ii) such Investor Shares not being redeemed in connection with the Meeting.

2. <u>[Reserved]</u>.

3. <u>Representations and Warranties of Investor</u>. Investor represents and warrants to, and agrees with,
the Sponsor that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.1. <u>No Government Recommendation or Approval</u>. Investor understands that no federal or state
agency has passed upon or made any recommendation or endorsement of the offering of the Promised Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.2. <u>Accredited Investor</u>. Investor is an institutional "accredited investor" within the
meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act of 1933, as amended, (the " <u>Securities Act</u> ") or
a "qualified institutional buyer" as defined in Rule 144A under the Securities Act, and acknowledges that the sale contemplated
hereby is being made in reliance, among other things, on a private placement exemption to "accredited investors" under the
Securities Act and similar exemptions under state law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.3. <u>Intent</u>. Investor is acquiring the Promised Securities solely for investment purposes,
for such Investor's own account (and/or for the account or benefit of its members or affiliates, as permitted), and not with a view
to the distribution thereof in violation of the Securities Act and Investor has no present arrangement to sell Promised Securities to
or through any person or entity except as may be permitted hereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.4. <u>Restrictions on Transfer; Trust Account; Redemption Rights</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.4.1. [Reserved.]

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.4.2. Investor acknowledges and agrees that the Promised Securities are not entitled to, and have no right,
interest or claim of any kind in or to, any monies held in the trust account into which the proceeds of WTMA's initial public offering
were deposited (the " <u>Trust Account</u> ") or distributed as a result of any liquidation of the Trust Account.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.4.3. Investor agrees, solely for the benefit of and, notwithstanding anything else herein, enforceable only
by WTMA, to waive any right that it may have to elect to have WTMA redeem any Investor Shares in connection with the Extension and agrees
not to redeem or otherwise exercise any right to redeem, the Investor Shares in connection with the Extension and to reverse and revoke
any prior redemption elections made with respect to the Investor Shares in connection with the Extension. For the avoidance of doubt,
nothing in this Agreement is intended to restrict or prohibit Investor's ability to redeem any Public Shares other than the Investor
Shares, or to trade or redeem any Public Shares (other than the Investor Shares) in its discretion and at any time or trade or redeem
any Investor Shares in its discretion and at any time after the date of the Meeting.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.4.4. Investor acknowledges and understands the Promised Securities will be offered by MergeCo in a transaction
not involving a public offering in the United States within the meaning of the Securities Act and have not been registered under the Securities
Act and, if in the future Investor decides to offer, resell, pledge or otherwise transfer Promised Securities, such Promised Securities
may be offered, resold, pledged or otherwise transferred only (A) pursuant to an effective registration statement filed under the
Securities Act, (B) pursuant to an exemption from registration under Rule 144 promulgated under the Securities Act, if available,
or (C) pursuant to any other available exemption from the registration requirements of the Securities Act, and in each case in accordance
with any applicable securities laws of any state or any other jurisdiction. Investor agrees that, if any transfer of the Promised
Securities or any interest therein is proposed to be made, as a condition precedent to any such transfer, Investor may be required to
deliver to MergeCo an opinion of counsel satisfactory to MergeCo that registration is not required with respect to the Promised Securities
to be transferred. Absent registration or another available exemption from registration, Investor agrees it will not transfer the Promised
Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.5. <u>Sophisticated Investor</u>. Investor is sophisticated in financial matters and able to evaluate the
risks and benefits of the investment in the Promised Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.6. <u>Risk of Loss</u>. Investor is aware that an investment in the Promised Securities is highly speculative
and subject to substantial risks. Investor is cognizant of and understands the risks related to the acquisition of the Promised Securities,
including those restrictions described or provided for in this Agreement pertaining to transferability under applicable securities laws. 
Investor is able to bear the economic risk of its investment in the Promised Securities for an indefinite period of time and able to sustain
a complete loss of such investment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.7. <u>Independent Investigation</u>. Investor has relied upon an independent investigation of
WTMA and has not relied upon any information or representations made by any third parties or upon any oral or written representations
or assurances, express or implied, from the Sponsor or any representatives or agents of the Sponsor, other than as set forth in this Agreement.
Investor is familiar with the business, operations and financial condition of WTMA and has had an opportunity to ask questions of, and
receive answers from WTMA's management concerning WTMA and the terms and conditions of the proposed sale of the Promised Securities
and has had full access to such other information concerning WTMA as Investor has requested. Investor confirms that all documents that
it has requested have been made available and that Investor has been supplied with all of the additional information concerning this investment
which Investor has requested.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.8. <u>Organization and Authority</u>. If an entity, Investor is duly organized and existing under
the laws of the jurisdiction in which it was organized and it possesses all requisite power and authority to acquire the Promised Securities,
enter into this Agreement and perform all the obligations required to be performed by Investor hereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.9. <u>Non-U.S. Investor</u>. If Investor is not a United States person (as defined by Section 7701(a)(30)
of the U.S. Internal Revenue Code of 1986, as amended, and the regulations promulgated thereunder (collectively, the " <u>Code</u> ")),
Investor hereby represents that it has satisfied itself as to the full observance of the laws of its jurisdiction in connection with any
invitation to subscribe for the Promised Securities or any use of this Agreement, including (i) the legal requirements within its jurisdiction
for the acquisition of the Promised Securities, (ii) any foreign exchange restrictions applicable to such acquisition, (iii) any governmental
or other consents that may need to be obtained, and (iv) the income tax and other tax consequences, if any, that may be relevant to the
acquisition, holding, redemption, sale, or transfer of the Promised Securities. Investor's subscription and payment for and continued
beneficial ownership of the Promised Securities will not violate any applicable securities or other laws of Investor's jurisdiction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.10. <u>Authority</u>. This Agreement has been validly authorized, executed and delivered by Investor and is
a valid and binding agreement enforceable in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy,
insolvency, fraudulent conveyance, moratorium, reorganization, or similar laws relating to, or affecting generally the enforcement of,
creditors' rights and remedies or by equitable principles of general application and except as enforcement of rights to indemnity
and contribution may be limited by federal and state securities laws or principles of public policy.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.11. <u>No Conflicts</u>. The execution, delivery and performance of this Agreement and the consummation by
Investor of the transactions contemplated hereby do not violate, conflict with or constitute a default under (i) Investor's
organizational documents, (ii) any agreement or instrument to which Investor is a party or (iii) any law, statute, rule or regulation
to which Investor is subject, or any order, judgment or decree to which Investor is subject, in the case of clauses (ii) and (iii), that
would reasonably be expected to prevent Investor from fulfilling its obligations under this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.12. <u>No Intent to Effect a Change of Control; Ownership</u>. Investor has no present intent to effect a
"change of control" of WTMA as such term is understood under the rules promulgated pursuant to Section 13(d) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), and under the rules of the Nasdaq.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.13. <u>No Advice from Sponsor</u>. Investor has had the opportunity to review this Agreement and the transactions
contemplated by this Agreement with Investor's own legal counsel and investment and tax advisors. Except for any statements
or representations of the Sponsor explicitly made in this Agreement, Investor is relying solely on such counsel and advisors and not on
any statements or representations, express or implied, of the Sponsor or any of its representatives or agents for any reason whatsoever,
including without limitation for legal, tax or investment advice, with respect to this investment, the Sponsor, WTMA, the Promised Securities,
the transactions contemplated by this Agreement or the securities laws of any jurisdiction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.14. <u>Reliance on Representations and Warranties</u>. Investor understands that the Promised Securities
are being offered and sold to Investor in reliance on exemptions from the registration requirements under the Securities Act, and analogous
provisions in the laws and regulations of various states, and that the Sponsor is relying upon the truth and accuracy of the representations,
warranties, agreements, acknowledgments and understandings of Investor set forth in this Agreement in order to determine the applicability
of such provisions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.15. <u>No General Solicitation</u>. Investor is not subscribing for Promised Securities as a result
of or subsequent to any general solicitation or general advertising, including but not limited to any advertisement, article, notice or
other communication published in any newspaper, magazine, or similar media or broadcast over television or radio or any seminar or meeting
whose attendees have been invited by any general solicitation or general advertising.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.16. <u>Brokers</u>. No broker, finder or intermediary has been paid or is entitled to a fee or commission
from or by Investor in connection with the acquisition of the Promised Securities nor is Investor entitled to or will accept any such
fee or commission.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.17. <u>No Pending Actions</u>. There is no action pending against Investor or, to Investor's knowledge,
threatened against Investor, before any court, arbitrator, or governmental authority, which in any manner challenges or seeks to prevent,
enjoin or materially delay the performance by Investor of its obligations under this Agreement.

4. <u>Representations and Warranties of Sponsor.</u> The Sponsor represents and warrants to, and agrees with,
the Investor that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.1. <u>Power and Authority</u>. The Sponsor is a limited liability company duly formed and validly existing
and in good standing as a limited liability company under the laws of Delaware and possesses all requisite limited liability company power
and authority to enter into this Agreement and to perform all of the obligations required to be performed by the Sponsor hereunder, including
the assignment, sale and transfer the Promised Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.2. <u>Authority</u>. All corporate action on the part of the Sponsor and its officers, directors and members
necessary for the authorization, execution and delivery of this Agreement and the performance of all obligations of the Sponsor required
pursuant hereto has been taken. This Agreement has been duly executed and delivered by the Sponsor and (assuming due authorization, execution
and delivery by Investor) constitutes the Sponsor's legal, valid and binding obligation, enforceable against the Sponsor in accordance
with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, fraudulent conveyance, moratorium,
reorganization, or similar laws relating to, or affecting generally the enforcement of, creditors' rights and remedies or by equitable
principles of general application and except as enforcement of rights to indemnity and contribution may be limited by federal and state
securities laws or principles of public policy.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.3. <u>Title to Securities</u>. The Sponsor shall cause the Promised Securities to be issued, when issued
to Investor by MergeCo as provided herein, to be free and clear of all liens, pledges, security interests, charges, claims, encumbrances, agreements,

5. <u>Trust Account</u>. Until the earlier of (a) the consummation of WTMA's initial business combination;

not effect a business combination prior to its termination date.

6. <u>Governing Law; Jurisdiction; Waiver of Jury Trial</u>. This Agreement shall be governed by and construed

thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.2. <u>Entire Agreement</u>. This Agreement sets forth the entire agreement and understanding between the

and (b) if by any other form of electronic transmission, when directed to such party.

9. <u>Counterparts</u>. This Agreement may be executed in two or more counterparts, all of which when taken

survive the closing of the transactions contemplated hereby.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10.2. <u>Severability</u>. In the event that any provision of this Agreement becomes or is declared by a court
of competent jurisdiction to be illegal, unenforceable or void, this Agreement shall continue in full force and effect without said provision;
provided that no such severability shall be effective if it materially changes the economic benefit of this Agreement to any party.

11. <u>Headings</u> *.* The titles and subtitles used in this Agreement are used for convenience only
and are not to be considered in construing or interpreting this Agreement.

12. <u>Disclosure; Waiver</u>. As soon as practicable, but in no event later than one business day, after
execution of this Agreement, WTMA will file (to the extent that it has not already filed) a Current Report on Form 8-K under the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), reporting the material terms of this Agreement. The parties to this
Agreement shall cooperate with one another to assure that such disclosure is accurate. WTMA agrees that the name of the investor shall
not be included in any public disclosures related to this Agreement unless required by applicable law, regulation or stock exchange rule.
Investor (i) acknowledges that the Sponsor may possess or have access to material non-public information which has not been communicated
to the Investor; (ii) hereby waives any and all claims, whether at law, in equity or otherwise, that he, she, or it may now have or may
hereafter acquire, whether presently known or unknown, against the Sponsor or any of WTMA's officers, directors, employees, agents,
affiliates, subsidiaries, successors or assigns relating to any failure to disclose any non-public information in connection with the
transaction contemplated by this Agreement, including any potential business combination involving WTMA, including without limitation,
any claims arising under Rule 10-b(5) of the Exchange Act; and (iii) is aware that the Sponsor is relying on the truth of the representations
set forth in Section 3 of this Agreement and the foregoing acknowledgement and waiver in this Section 12, in connection with the transactions
contemplated by this Agreement. WTMA shall, by 9:30 a.m., New York City time, on the first business day immediately following the date
of the Meeting, issue one or more press releases or file with the United States Securities and Exchange Commission a Current Report on
Form 8-K (collectively, the " <u>Disclosure Document</u> ") disclosing, to the extent not previously publicly disclosed, all
material terms of the transactions contemplated hereby and any other material, nonpublic information that WTMA has provided to Investor
at any time prior to the filing of the Disclosure Document. Upon the issuance of the Disclosure Document, to WTMA's knowledge, Investor
shall not be in possession of any material, nonpublic information received from WTMA or any of its officers, directors or employees.

13. <u>Independent Nature of Rights and Obligations</u>. Nothing contained herein, and no action taken by
any party pursuant hereto, shall be deemed to constitute Investor and the Sponsor as, and the Sponsor acknowledges that Investor and the
Sponsor do not so constitute, a partnership, an association, a joint venture or any other kind of entity, or create a presumption that
Investor and the Sponsor are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated
by this Agreement or any matters, and the Sponsor acknowledges that Investor and the Sponsor are not acting in concert or as a group,
and the Sponsor shall not assert any such claim, with respect to such obligations or the transactions contemplated by this Agreement.

14. <u>Most Favored Nation</u>. In the event the Sponsor or WTMA enter one or more other non-redemption agreements
before or after the execution of this Agreement in connection with the Meeting, the Sponsor and WTMA represent that the terms of such
other agreements are not materially more favorable to such other investors thereunder than the terms of this Agreement are in respect
of the Investor. In the event that another investor is afforded any such more favorable terms than the Investor, the Sponsor shall promptly
inform the Investor of such more favorable terms in writing, and the Investors shall have the right to elect to have such more favorable
terms included herein, in which case the parties hereto shall promptly amend this Agreement to effect the same.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed as of the date first above written.
