Item 1.01 Entry into a Definitive Material Agreement

As previously disclosed on a Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) on December 12, 2022, on December 8, 2022, GigCapital5, Inc. (“GigCapital5” or the “Company”) entered into a Business Combination Agreement (as amended, the “BCA”) with QTI Merger Sub, Inc., a Delaware corporation and wholly owned subsidiary of GigCapital5 (“Merger Sub”), and QT Imaging, Inc. (“QT Imaging” and transactions contemplated by the BCA, the “Business Combination”). Pursuant to the terms of the BCA, Merger Sub will merge with and into QT Imaging (the “Merger”), with QT Imaging as the surviving company in the Merger, which after giving effect to the Merger will be a wholly owned subsidiary of GigCapital5 and will be renamed as QT Imaging Holdings, Inc. (“QTI Holdings” or the “Combined Company” and the shares of common stock of the Combined Company, the “QTI Holdings Common Stock”).

By entering into the Amended Non-Redemption Agreement (as defined below) and the Subscription Agreements (as defined below), an aggregate of $1.35 million of service fees that would otherwise be payable to various service providers by the Combined Company following the closing of the Business Combination in cash, will be satisfied in full in exchange for the issuance of a total number of shares of QT Imaging that will convert in accordance with the terms of the BCA into an aggregate of 540,000 shares of QTI Holdings upon the consummation of the Business Combination, with no change in the total number of shares issued by GigCapital5 as merger consideration in connection with the Business Combination.

As previously disclosed on a Current Report on Form 8-K filed with the SEC on September 27, 2023, GigCapital5, QT Imaging, and Mizuho Securities USA LLC ( “Mizuho”) entered into that certain Non-Redemption Agreement (the “Prior Non-Redemption Agreement”) on September 25, 2023, pursuant to which Mizuho agreed not to redeem its holdings of common stock, par value $0.0001 per share, of the Company (the “GigCapital5 Common Stock”, and such shares that were not redeemed, the “Non-Redeemed GigCapital5 Shares”) in connection with the special meeting of the stockholders of GigCapital5 held on September 28, 2023 (the “Special Meeting”), in consideration for the issuance to Mizuho of that number of shares of common stock of QT Imaging (the “QTI Shares”) equal to the result of: (i)(A) the number of Non-Redeemed GigCapital5 Shares of Mizuho multiplied by (B) 0.15, divided by (ii) the Exchange Ratio (as defined in the BCA), such that at the closing of the Business Combination, Mizuho will receive that consideration provided for in the BCA that a holder of QTI Shares is entitled to receive, including that number of shares of QTI Holdings Common Stock equal to (A) the number of Non-Redeemed GigCapital5 Shares of Mizuho multiplied by (B) 0.15 (the Merger Consideration QTI Holdings Shares”) upon the terms set forth in the Prior Non-Redemption Agreement.

On February 21, 2024, the parties agreed to amend the Prior Non-Redemption Agreement (as amended, the “Amended Non-Redemption Agreement”) to provide that in addition to the Merger Consideration QTI Holdings Shares issuable to Mizuho under the Prior Non-Redemption Agreement, Mizuho shall receive from QT Imaging, in exchange for $250,000 of services rendered by Mizuho, that number of QTI Shares (the “Services Share Issuance”) that will be converted in accordance with the terms of the BCA into 100,000 shares of QTI Holdings Common Stock .

AMENDED AND RESTATED NON-REDEMPTION AGREEMENT

This Amended and Restated Non-Redemption Agreement (this “Agreement”) is entered into as of February 21, 2024, by and among the entities listed on Exhibit A (collectively, the “Holder”), QT Imaging, Inc., a Delaware corporation (“QT Imaging”), and GigCapital5, Inc., a Delaware corporation (the “Company”).

RECITALS:

A. The Company and QT Imaging are the parties to the Business Combination Agreement dated December 8, 2023, as amended (the “BCA”), pursuant to which QTI Merger Sub, Inc., a Delaware corporation and wholly owned subsidiary of the Company, will merge with and into QT Imaging (the “Merger” and, together with the other transactions contemplated by the BCA and any other agreement executed and delivered in connection therewith, the “Business Combination”), with QT Imaging as the surviving company in the Merger (the “Surviving Corporation”), and after giving effect to the Merger, the Surviving Corporation will be a wholly owned subsidiary of the Company, which will be renamed as QT Imaging Holdings, Inc.

B. The Company held on September 28, 2023 a special meeting of its stockholders (the “Meeting”) at which the stockholders approved, among other things, a proposal (the “Extension Proposal”) to extend the time the Company has to consummate an initial business combination from 24 months from the completion of the Company’s initial public offering to December 31, 2023 (the “Extension”).

C. On September 25, 2023, the Holder and the Company entered into that certain Non-Redemption Agreement, by and among the Holder, QT Imaging and the Company (the “Prior Agreement”), pursuant to which, in connection with the Extension Meeting, the Holder agreed not to request the redemption in connection with the Extension, and to reverse any previously submitted redemption demand, of certain shares of the common stock, par value $0.0001 per share, of the Company (the “GigCapital5 Common Stock”) issued in the Company’s initial public offering held by such Holder, in consideration for the issuance to the Holder of the Merger Consideration GigCapital5 Shares (as defined below), upon the terms set forth in the Prior Agreement.

D. The Holder and the Company now desire to enter into this Agreement, which amends the Prior Agreement to provide that in addition to the Merger Consideration GigCapital5 Shares issuable to the Holder under the Prior Agreement, the Holder shall receive from QT Imaging (the “Services Share Issuance”) in exchange for services rendered by the Holder in connection with an extension that occurred in March 2023, immediately prior to the consummation of the Business Combination, that number of QTI Shares equal to the result of (x) 100,000 divided by (y) the Exchange Ratio (as defined in the BCA), as set forth on Exhibit A hereto (the “Services Consideration Shares”), all on the terms and subject to the conditions set forth herein.

IT IS AGREED:

1. Non-Redemption. The Holder hereby agrees either not to request redemption in connection with the Extension or to reverse any previously submitted redemption demand in connection with the Extension with respect to the aggregate number of shares of GigCapital5 Common Stock set forth on Exhibit A hereto (“Non-Redeemed GigCapital5 Shares”) it holds; provided that in no event will Holder be required to hold a number of shares of GigCapital5 Common Stock representing in excess of 9.9% of the total number of shares of GigCapital5 Common Stock outstanding following the effectuation of the Extension Proposal. The Non-Redeemed GigCapital5 Shares held by the Holder shall not be subject to any transfer restrictions other than with respect to this Section 1, and the Holder shall have no obligation to hold any shares of GigCapital5 Common Stock following the date of the Meeting. Nothing in this Agreement is intended to restrict or prohibit the Holder’s ability to redeem any shares of GigCapital5 Common Stock other than the Non-Redeemed GigCapital5 Shares. The Company shall provide the Holder with the final number of the GigCapital5 Common Stock immediately following completion of the Extension no later than 9:00 AM Eastern Time on the date of the Meeting (or such earlier time as necessary to allow Holder the reasonable opportunity to reverse any previously submitted redemption demand in connection with the Extension).

2. Issuance of QTI Shares.

(a) In consideration of the agreement set forth in Section 1 hereof, immediately prior to, and substantially concurrently with, the closing of the Business Combination (“Closing”), QT Imaging shall issue (the “Share Issuance”) to the Holder that number of shares of common stock of QT Imaging (the “QTI Shares”) equal to the result of: (i)(A) the number of Non-Redeemed GigCapital5 Shares of such Holder multiplied by (B) 0.15, divided by (ii) the Exchange Ratio, such that at the Closing, the Holder will receive that consideration provided for in the BCA that a holder of QTI Shares is entitled to receive pursuant to the BCA, including that number of shares of GigCapital5 Common Stock equal to (A) the number of Non-Redeemed GigCapital5 Shares of such Holder multiplied by (B) 0.15 (the “Merger Consideration GigCapital5 Shares”). In addition, the Holder shall receive from QT Imaging the Services Consideration Shares, such that at the Closing, the Holder will receive that number of shares of GigCapital5 Common Stock equal to (x) the number of Services Consideration Shares multiplied by (y) the Exchange Ratio (the “Services Consideration GigCapital5 Shares”). The QTI Shares and the Services Consideration Shares shall be issued directly to the Holder in book-entry form on the books and records of QTI Imaging, and the Merger Consideration GigCapital5 Shares into which the QTI Shares will convert at the Closing and the Services Consideration GigCapital5 Shares into which the Services Consideration Shares will convert at the Closing shall be issued directly to the Holder in book-entry form on the books and records of the Company’s transfer agent in accordance with the terms of the BCA.

(b) The Holder shall not be required to forfeit, transfer or refrain from transferring any Merger Consideration GigCapital5 Shares or Services Consideration GigCapital5 Shares received by it pursuant to Section 2(a). QT Imaging and the Company acknowledge and agree that any QTI Shares or Services Consideration Shares received by the Holder in the Share Issuance or Services Share Issuance, or Merger Consideration GigCapital5 Shares into which such QTI Shares shall convert at the Closing or Services Consideration GigCapital5 Shares into which such Services Consideration Shares shall convert at the Closing, shall not be changed as a result of or subject to any earn-outs, forfeitures, transfers, restrictions, amendments or other arrangements agreed to by QT Imaging with respect to its other QTI Shares or by GigCapital5 with respect to its other shares of GigCapital5 Common Stock.

3. Representations of the Holder. The Holder hereby represents and warrants to QT Imaging and the Company that:

(a) The Holder, in making the decision to receive the QTI Shares and the Services Consideration Shares from QT Imaging pursuant to this Agreement, has not relied upon any oral or written representations or assurances from QT Imaging or the Company or any of QT Imaging’s or the Company’s officers, directors, partners or employees or any other representatives or agents.

4. QT Imaging Representations. QT Imaging hereby represents and warrants to the Holder that:

(a) This Agreement has been validly authorized, executed and delivered by it and, assuming the due authorization, execution and delivery thereof by the other parties hereto, is a valid and binding agreement enforceable in accordance with its terms, subject to the general principles of equity and to bankruptcy or other laws affecting the enforcement of creditors’ rights generally.

3

(b) The Company has filed a registration statement on Form S-4 (the “Registration Statement”) with the U.S. Securities and Exchange Commission (the “SEC”) which the SEC declared effective on February 6, 2024, and that the Closing will not occur until such time as determined by QT Imaging and the Company. The Merger Consideration GigCapital5 Shares and the Services Consideration GigCapital5 Shares into which the QTI Shares and the Services Consideration Shares will be converted at the Closing will be issued by the Company pursuant to the Registration Statement.

(c) The Company has not disclosed to the Holder material non-public information with respect to the Company.

(d) There is no action pending against the Company or, to the Company’s knowledge, threatened against the Company, before any court, arbitrator, or governmental authority, which in any manner challenges or seeks to prevent, or enjoin or materially delay the performance by the Company of its obligations under this Agreement.

6. Disclosure; Exchange Act Filings. As soon as practicable but in no event later than one business day after execution of this Agreement, the Company will file 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. QT Imaging and the Company agree that the name of the Holder shall not be included in any public disclosures related to this Agreement unless required by applicable law, regulation or stock exchange rule.

7. Trust Account. Until the earlier of (a) the consummation of the Business Combination; (b) the liquidation of the trust account established for the benefit of the Company’s public stockholders in connection with the Company’s initial public offering (the “Trust Account”); and (c) December 31, 2023, or such later time as the stockholders of the Company may approve, the Company will maintain the investment of funds held in the Trust Account in interest-bearing United States government securities within the meaning of Section 2(a)(16) of the Investment Company Act of 1940, as amended, having a maturity of 185 days or less, or in money market funds meeting the conditions of paragraphs (d)(1), (d)(2), (d)(3) and (d)(4) of Rule 2a-7 promulgated under the Investment Company Act of 1940, as amended, which invest only in direct U.S. government treasury obligations, or maintain such funds in cash in an interest-bearing demand deposit account at a bank. In order to mitigate the current uncertainty surrounding the implementation of the Inflation Reduction Act of 2022, the Company further confirms that it will not utilize any funds from its Trust Account to pay any potential excise taxes that may become due pursuant to the Inflation Reduction Act of 2022 upon a redemption of shares of the GigCapital5 Common Stock, including in connection with a liquidation of the Company if it does not effect a business combination prior to its termination date.

8. Entire Agreement: Amendment. This Agreement constitutes the entire agreement among the parties with respect to the subject matter hereof and may be amended or modified only by written instrument signed by all parties. The headings in this Agreement are for convenience of reference only and shall not alter or otherwise affect the meaning hereof.

9. Governing Law. This Agreement shall be governed by and construed in accordance with the law of the State of New York, including the conflicts of law provisions and interpretations thereof.

10. Counterparts. This Agreement may be executed in one or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement. Delivery of an executed signature page by facsimile or other electronic transmission shall be effective as delivery of a manually signed counterpart of this Agreement.

11. Termination. This Agreement shall become null and void and of no force and effect upon the earliest to occur of: (a) the mutual written consent of the parties hereto; and (b) the delivery of the QTI Shares and the Services Consideration Shares to the Holder. Notwithstanding any provision in this Agreement to the contrary, QT Imaging’s obligation to issue the QTI Shares and the Services Consideration Shares to the Holder shall only take place immediately prior to, and substantially concurrently with, the Closing.

4

12. Remedies. Each of the parties hereto acknowledges and agrees that, in the event of any breach of any covenant or agreement contained in this Agreement by another party, money damages may be inadequate with respect to any such breach and the non-breaching party may have no adequate remedy at law. It is accordingly agreed that each of the parties hereto shall be entitled, in addition to any other remedy to which they may be entitled at law or in equity, to seek injunctive relief and/or to compel specific performance to prevent breaches by the other party hereto of any covenant or agreement of such other party contained in this Agreement.

13. Acknowledgement; Waiver. Holder (i) acknowledges that QT Imaging or the Company may possess or have access to material non-public information which has not been communicated to the Holder; (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 QT Imaging, the Company or any of their respective 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 without limitation, any claims arising under Rule 10b-5 promulgated under the Exchange Act; and (iii) is aware that QT Imaging and the Company are relying on the truth of the representations set forth in Section 3 of this Agreement and the foregoing acknowledgement and waiver in clauses (i) and (ii) above, respectively, in connection with the transactions contemplated by this Agreement.

14. Binding Effect; Assignment. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective legal representatives, successors and permitted assigns. This Agreement shall not be assigned by any party without the prior written consent of the other parties hereto; provided, that no such consent shall be required for any such assignment by Investor to one or more affiliates thereof.

15. Most Favored Nation. In the event QT Imaging or the Company enters one or more other non-redemption agreements in connection with the Extension (“Other Agreements”) before or after the execution of this Agreement, QT Imaging and the Company represent that the terms of such Other Agreements will not be materially more favorable to such other investors thereunder than the terms of this Agreement are in respect of the Holder. To avoid doubt, the Company and QT Imaging acknowledge and agree that a ratio of Non-Redeemed GigCapital5 Shares to QTI Shares issuable in the Share Issuance in any such Other Agreement in connection with the Extension that is more favorable to such other investors thereunder than such ratio in this Agreement is to the Holder would be materially more favorable to such other investors. In the event that another third party is afforded any such more favorable terms than the Holder, QT Imaging and the Company shall promptly inform the Holder of such more favorable terms in writing, and the Holder 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.

Furthermore, SPAC acknowledges and agrees that it owes and must pay the Service Fee to Subscriber in immediately available funds if the Closing does not occur prior to March 31, 2024.

(c) No Conflicts. The execution, delivery and performance by SPAC of this Subscription Agreement and the consummation by SPAC of the transactions contemplated hereby will not (i) result in a violation of the organizational documents of SPAC, or (ii) conflict with, or constitute a default (or an event which with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, any agreement, indenture or instrument to which SPAC is a party, or (iii) result in a violation of any law, rule, regulation, order, judgment or decree (including federal and state securities laws) applicable to SPAC, except in the case of clauses (ii) and (iii) above, for such conflicts, defaults, rights or violations which could not, individually or in the aggregate, reasonably be expected to have a material adverse effect on the ability of SPAC to perform its obligations hereunder.

Section 5. Subscriber Representations and Warranties. Subscriber represents and warrants to the Company and SPAC that, as of the date hereof and as of the Closing Date:

(a) Organization; Authority. Subscriber is an entity duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization with the requisite power and authority to enter into and to consummate the transactions contemplated by the Transaction Documents (as defined below) to which it is a party and otherwise to carry out its obligations hereunder. “Transaction Documents” means, collectively, this Subscription Agreement, the Irrevocable Transfer Agent Instructions (as defined below) and each of the other agreements and instruments entered into or delivered by any of the parties hereto in connection with the transactions contemplated hereby and thereby, as may be amended from time to time.

(b) No Public Sale or Distribution. Subscriber is acquiring the Subscribed Shares for its own account and not with a view towards, or for resale in connection with, the public sale or distribution thereof in violation of applicable securities laws, except pursuant to sales registered or exempted under the 1933 Act; provided, however, by making the representations herein, Subscriber does not agree, or make any representation or warranty, to hold any of the Subscribed Shares for any minimum or other specific term and reserves the right to dispose of the Subscribed Shares at any time in accordance with or pursuant to a registration statement or an exemption from registration under the 1933 Act. Subscriber does not presently

have any agreement or understanding, directly or indirectly, with any Person to distribute any of the Subscribed Shares in violation of applicable securities laws. For purposes of this Subscription Agreement, “Person” means an individual, a limited liability company, a partnership, a joint venture, a corporation, a trust, an unincorporated organization, any other entity and any Governmental Entity (as defined below) or any department or agency thereof. “Governmental Entity” means any nation, state, county, city, town, village, district, or other political jurisdiction of any nature, federal, state, local, municipal, foreign, or other government, governmental or quasi-governmental authority of any nature (including any governmental agency, branch, department, official, or entity and any court or other tribunal), multi-national organization or body; or body exercising, or entitled to exercise, any administrative, executive, judicial, legislative, police, regulatory, or taxing authority or power of any nature or instrumentality of any of the foregoing, including any entity or enterprise owned or controlled by a government or a public international organization or any of the foregoing.

(c) Accredited Investor Status. Subscriber is an “accredited investor” as that term is defined in Rule 501(a) of Regulation D, satisfying the applicable requirements set forth on Annex A hereto, and has provided the Company with the requested information on Annex A following the signature page hereto.

(d) Reliance on Exemptions. Subscriber understands that the Subscribed Shares are being offered and sold to it in reliance on specific exemptions from the registration requirements of United States federal and state securities laws and that the Company is relying in part upon the truth and accuracy of, and Subscriber’s compliance with, the representations, warranties, agreements, acknowledgments and understandings of Subscriber set forth herein in order to determine the availability of such exemptions and the eligibility of Subscriber to acquire the Subscribed Shares.

(e) Information. Subscriber and its advisors, if any, have been furnished with all materials relating to the business, finances and operations of the Company and materials relating to the offer and sale of the Subscribed Shares that have been requested by Subscriber. Subscriber and its advisors, if any, have been afforded the opportunity to ask questions of the Company. Subscriber understands that its investment in the Subscribed Shares involves a high degree of risk. Subscriber has sought such accounting, legal and tax advice as it has considered necessary to make an informed investment decision with respect to its acquisition of the Subscribed Shares.

(f) No Governmental Review. Subscriber understands that no United States federal or state agency or any other government or governmental agency has passed on or made any recommendation or endorsement of the Subscribed Shares or the fairness or suitability of the investment in the Subscribed Shares nor have such authorities passed upon or endorsed the merits of the offering of the Subscribed Shares.

(g) Transfer or Resale. Subscriber understands that: (i) the Subscribed Shares have not been registered under the 1933 Act or any state securities laws, and may not be offered for sale, sold, assigned or transferred unless (A) subsequently registered, or (B) Subscriber provides the Company with reasonable assurance that such Subscribed Shares can be sold, assigned or transferred pursuant to Rule 144 or Rule 144A promulgated under the 1933 Act (or a successor rule thereto) (collectively, “Rule 144”); and (ii) any sale of the Subscribed Shares made in reliance on Rule 144 may be made only in accordance with the terms of Rule 144, and further, if Rule 144 is not applicable, any resale of the Subscribed Shares under circumstances in which the seller (or the Person through whom the sale is made) may be deemed to be an underwriter (as that term is defined in the 1933 Act) may require compliance with some other exemption under the 1933 Act or the rules and regulations of the SEC promulgated thereunder. Notwithstanding the foregoing, the Exchange Securities to be received by Subscriber upon consummation of the Transactions in exchange for the Subscribed Shares shall be registered under the 1933 Act and freely tradeable immediately following consummation of the Transactions, and the Subscribed Shares may be pledged in connection with a bona fide margin account or other loan or financing arrangement secured by the

5

Subscribed Shares and such pledge of Subscribed Shares shall not be deemed to be a transfer, sale or assignment of the Subscribed Shares hereunder, and no Subscriber effecting a pledge of Subscribed Shares shall be required to provide the Company with any notice thereof or otherwise make any delivery to the Company pursuant to this Subscription Agreement, including, without limitation, this Section 5(g).

(h) Validity; Enforcement. This Subscription Agreement has been duly and validly authorized, executed and delivered on behalf of Subscriber and shall constitute the legal, valid and binding obligations of Subscriber enforceable against Subscriber in accordance with their respective terms, except as such enforceability may be limited by general principles of equity or to applicable bankruptcy, insolvency, reorganization, moratorium, liquidation and other similar laws relating to, or affecting generally, the enforcement of applicable creditors’ rights and remedies.

(i) No Conflicts. The execution, delivery and performance by Subscriber of this Subscription Agreement and the consummation by Subscriber of the transactions contemplated hereby will not (i) result in a violation of the organizational documents of Subscriber, or (ii) conflict with, or constitute a default (or an event which with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, any agreement, indenture or instrument to which Subscriber is a party, or (iii) result in a violation of any law, rule, regulation, order, judgment or decree (including federal and state securities laws) applicable to Subscriber, except in the case of clauses (ii) and (iii) above, for such conflicts, defaults, rights or violations which could not, individually or in the aggregate, reasonably be expected to have a material adverse effect on the ability of Subscriber to perform its obligations hereunder.

Section 6. Register; Transfer Agent Instructions; Legend.

(a) Register. The Company shall maintain at its principal executive offices (or such other office or agency of the Company as it may designate by notice to each holder of Subscribed Shares), a stock ledger for the Subscribed Shares in which the Company shall record the name and address of the Person in whose name the Subscribed Shares have been issued (including the name and address of each transferee) and the number of Subscribed Shares held by such Person. The Company shall keep the stock ledger open and available at all times during business hours for inspection of Subscriber or its legal representatives. If Subscriber effects a sale, assignment or transfer of the Subscribed Shares in accordance with Section 5(g), the Company shall permit the transfer and shall promptly record in its stock ledger for the Subscribed Shares, such name and such denominations as specified by Subscriber to effect such sale, transfer or assignment.

(b) Transfer Agent Instructions. Upon the consummation of the Transactions, the SPAC shall issue irrevocable instructions to its transfer agent and any subsequent transfer agent (as applicable, the “Transfer Agent”) in a form acceptable to Subscriber (the “Irrevocable Transfer Agent Instructions”) to issue certificates or credit shares to the applicable balance accounts at The Depository Trust Company (“DTC”), registered in the name of Subscriber or its respective nominee(s), for the Exchange Securities in such amounts as in accordance with the terms of the Business Combination Agreement. The SPAC represents and warrants that no instruction other than the Irrevocable Transfer Agent Instructions referred to in this Section 6(b) will be given by the SPAC to the Transfer Agent with respect to the Exchange Securities, and that the Exchange Securities shall otherwise be freely transferable on the books and records of the SPAC to the extent provided in this Subscription Agreement and the Business Combination Agreement. In the event that a sale, assignment or transfer involves Exchange Securities sold, assigned or transferred pursuant to an effective registration statement or in compliance with Rule 144, and the Transfer Agent has not already issued the Exchange Securities as credit shares to the applicable balance accounts at DTC, the Transfer Agent shall issue such shares to such Subscriber, assignee or transferee (as the case may be) without any restrictive legend in accordance with Section 6(d) below. Each of the Company and SPAC acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to Subscriber.

6

Accordingly, each of the Company and SPAC acknowledges that the remedy at law for a breach of its obligations under this Section 6(b) will be inadequate and agrees, in the event of a breach or threatened breach by the Company of the provisions of this Section 6(b), that Subscriber shall be entitled, in addition to all other available remedies, to an order and/or injunction restraining any breach and requiring immediate issuance and transfer, without the necessity of showing economic loss and without any bond or other security being required. The SPAC shall cause its counsel to issue the legal opinion referred to in the Irrevocable Transfer Agent Instructions to the Transfer Agent following the consummation of the Transactions. Any fees (with respect to the Transfer Agent, counsel to the Company or SPAC or otherwise) associated with the issuance of such opinion or the removal of any legends on any of the Subscribed Shares or the Exchange Securities shall be borne by the Company and SPAC, jointly.

(c) Legends. Subscriber understands that the Subscribed Shares have been issued pursuant to an exemption from registration or qualification under the 1933 Act and applicable state securities laws, and except as set forth below, the Subscribed Shares shall bear any legend as required by the “blue sky” laws of any state and a restrictive legend in substantially the following form (and a stop-transfer order may be placed against transfer of such stock certificates):

THE ISSUANCE AND SALE OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (I) IN THE ABSENCE OF (A) AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR (B) AN OPINION OF COUNSEL TO THE HOLDER (IF REQUESTED BY THE COMPANY), IN A FORM REASONABLY ACCEPTABLE TO THE COMPANY, THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR (II) UNLESS SOLD OR ELIGIBLE TO BE SOLD PURSUANT TO RULE 144 OR RULE 144A UNDER SAID ACT. NOTWITHSTANDING THE FOREGOING, THE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN OR FINANCING ARRANGEMENT SECURED BY THE SECURITIES.

(d) Removal of Legends. Upon the closing of the Transactions, in accordance with the terms of the Business Combination Agreement, the Exchange Securities shall be issued without any legends.

Section 7. Termination. This Subscription Agreement shall terminate and be void and of no further force and effect, and all rights and obligations of the parties hereunder shall terminate without any further liability on the part of any party in respect thereof, upon the earliest to occur of (a) such date and time as the Business Combination Agreement is terminated in accordance with its terms and (b) the mutual written agreement of the parties hereto to terminate this Subscription Agreement; provided, that if any of the conditions to the obligations of Subscriber and the Company to consummate, or cause to be consummated, the transactions contemplated by this Subscription Agreement (including the Closing) set forth in Sections 3(d), (e) or (f) are not satisfied on the Closing Date, this Subscription Agreement shall be terminable by any of the Company or Subscriber upon written notice of termination delivered in accordance with Section 9(a); provided further, that nothing herein will relieve any party from liability for any willful breach hereof prior to the time of termination, and each party will be entitled to any remedies at law or in equity to recover losses, liabilities or damages arising from such breach. The Company shall notify Subscriber of the termination of the Business Combination Agreement promptly after the termination thereof. Upon the termination hereof in accordance with this Section 7, any monies paid by Subscriber to the Company in connection herewith shall promptly (and in any event within one Business Day) be returned in full to Subscriber by wire transfer of U.S. dollars in immediately available funds to the account specified by Subscriber, without any deduction for or on account of any tax withholding, charges or set-off, whether or not the Transactions shall have been consummated.

Section 8. Trust Account Waiver. Subscriber hereby acknowledges that, as described in SPAC’s prospectus relating to its initial public offering (the “IPO”) dated September 23, 2021 available at www.sec.gov, SPAC has established a trust account (the “Trust Account”) containing the proceeds of the IPO and from certain private placements occurring simultaneously with the IPO (including interest accrued from time to time thereon) for the benefit of SPAC, its public shareholders and certain other parties (including the underwriters of the IPO), and that, except as otherwise described in such prospectus, SPAC may disburse monies from the Trust Account only to (x) its public shareholders in the event they elect to have their shares of SPAC Common Stock redeemed for cash in connection with the consummation of SPAC’s initial business combination, an amendment to its certificate of incorporation, as amended and rested and as in effect on the date hereof (the “SPAC Charter”) to extend the deadline by which SPAC must consummate its initial business combination, or SPAC’s failure to consummate an initial business combination by such deadline, (y) pay certain taxes from time to time, or (z) SPAC after or concurrently with the consummation of its initial business combination. For and in consideration of SPAC entering into this Subscription Agreement, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Subscriber, on behalf of itself and its affiliates, hereby (a) agrees that it does not now and shall not at any time hereafter have any right, title, interest or claim of any kind in or to any assets held in the Trust Account, and shall not make any claim against the Trust Account, arising out or as a result of, in connection with or relating in any way to this Subscription Agreement, and regardless of whether such claim arises based on contract, tort, equity or any other theory of legal liability (any and all such claims are collectively referred to hereafter as the “Released Claims”), (b) irrevocably waives any Released Claims that it may have against the Trust Account now or in the future as a result of, or arising out of, this Subscription Agreement, and (c) will not seek recourse against the Trust Account as a result of, in connection with or relating in any way to this Subscription Agreement. Subscriber acknowledges and agrees that such irrevocable waiver is a material inducement to SPAC to enter into this Subscription Agreement, and further intends and understands such waiver to be valid, binding, and enforceable against Subscriber in accordance with applicable law. To the extent Subscriber commences any action or proceeding based upon, in connection with, relating to or arising out of any matter relating to SPAC or its Representatives, which proceeding seeks, in whole or in part, monetary relief against SPAC or its Representatives, Subscriber hereby acknowledges and agrees that its sole remedy shall be against funds held outside of the Trust Account and that such claim shall not permit Subscriber (or any person claiming on Subscriber’s behalf or in lieu of Subscriber) to have any claim against the Trust Account (including any distributions therefrom) or any amounts contained therein. Nothing in this Section 8 shall be deemed to limit Subscriber’s right to distributions from the Trust Account in accordance with the SPAC Charter, in respect of any redemptions by Subscriber in respect of shares of SPAC Common Stock. Notwithstanding anything in this Subscription Agreement to the contrary, the provisions of this Section 8 shall survive termination of this Subscription Agreement.

Section 9. Miscellaneous.

Prior to the Closing, Subscriber agrees to promptly notify the Company if it becomes aware that any of the acknowledgments, understandings, agreements, representations and warranties of Subscriber set forth herein are no longer accurate in all material respects. The Company and SPAC each acknowledges that Subscriber and the Company, SPAC and their respective subsidiaries will rely on the acknowledgments, understandings, agreements, representations and warranties contained in this Subscription Agreement.

(f) All the agreements, representations and warranties made by each party hereto in this Subscription Agreement shall survive the Closing.

(g) The Company may request from Subscriber such additional information as the Company may reasonably deem necessary to evaluate the eligibility of Subscriber to acquire the Subscribed Shares, and Subscriber shall promptly provide such information as may be reasonably requested, to the extent readily available and to the extent consistent with its internal policies and procedures; provided, that the Company agrees to keep any such information provided by Subscriber confidential, except (A) as required by the federal securities laws, rules or regulations and (B) to the extent such disclosure is required by other laws, rules or regulations, at the request of the staff of the Commission or regulatory agency or under the regulations of the Stock Exchange. Subscriber acknowledges that the Company may file a form of this Subscription Agreement with the Commission as an exhibit to a current or periodic report of the Company, a proxy statement of the Company or a registration statement of the Company.

(h) This Subscription Agreement may not be amended, modified or waived except by an instrument in writing, signed by each of the parties hereto.

(i) This Subscription Agreement constitutes the entire agreement, and supersedes all other prior agreements, understandings, representations and warranties, both written and oral, among the parties, with respect to the subject matter hereof; provided, however, that if the consummation of the Transactions does not occur, Subscriber retains the right to demand the payment of the Service Fee pursuant to the terms of the Financial Printing Services Quotation between SPAC, or one of SPAC’s affiliates GIGAcquisitions, Inc. or its principal agents, and Subscriber (“IPO Proposal”). Furthermore, it is agreed that the Service Fee relates only to services rendered in connection with the Transactions and that other amounts may be owed by SPAC or its affiliates under such IPO Proposal for other services rendered.

(j) Except as otherwise provided herein, this Subscription Agreement is intended for the benefit of the parties hereto and their heirs, executors, administrators, successors, legal representatives, and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other person. Except as set forth in Section 6, Section 8, Section 9(b), Section 9(c), Section 9(e), Section 9(h) and this Section 9(j) with respect to the persons specifically referenced therein, this Subscription Agreement shall not confer any rights or remedies upon any person other than the parties hereto, and their respective successors and assigns.

(k) The parties hereto acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Subscription Agreement were not performed in accordance with their specific terms or were otherwise breached and that money or other legal remedies would not be an adequate remedy for such damage. It is accordingly agreed that the parties shall be entitled to equitable relief, including in the form of an injunction or injunctions to prevent breaches or threatened breaches of this Subscription Agreement and to enforce specifically the terms and provisions of this Subscription Agreement, this being in addition to any other remedy to which such party is entitled at law, in equity, in contract, in tort or otherwise. The parties hereto acknowledge and agree that the Company shall be entitled to specifically enforce Subscriber’s obligations to fund the Subscription and the provisions of the Subscription Agreement, in each case, on the terms and subject to the conditions set forth herein. The parties hereto further acknowledge and agree: (x) to waive any requirement for the security or posting of any bond in connection with any such equitable remedy; (y) not to assert that a remedy of specific enforcement pursuant to this Section 9(k) is unenforceable, invalid, contrary to applicable law or inequitable for any reason; and (z) to waive any defenses in any action for specific performance, including the defense that a remedy at law would be adequate.

(l) If any provision of this Subscription Agreement shall be invalid, illegal or unenforceable, the validity, legality or enforceability of the remaining provisions of this Subscription Agreement shall not in any way be affected or impaired thereby and shall continue in full force and effect.

(m) No failure or delay by a party hereto in exercising any right, power or remedy under this Subscription Agreement, and no course of dealing between the parties hereto, shall operate as a waiver of any such right, power or remedy of such party. No single or partial exercise of any right, power or remedy under this Subscription Agreement by a party hereto, nor any abandonment or discontinuance of steps to enforce any such right, power or remedy, shall preclude such party from any other or further exercise thereof or the exercise of any other right, power or remedy hereunder. The election of any remedy by a party hereto shall not constitute a waiver of the right of such party to pursue other available remedies. No notice to or demand on a party not expressly required under this Subscription Agreement shall entitle the party receiving such notice or demand to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the party giving such notice or demand to any other or further action in any circumstances without such notice or demand.

10

(n) This Subscription Agreement may be executed and delivered in one or more counterparts (including by electronic mail, in .pdf or other electronic submission) and by different parties in separate counterparts, with the same effect as if all parties hereto had signed the same document. All counterparts so executed and delivered shall be construed together and shall constitute one and the same agreement.

(o) This Subscription Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, without regard to the principles of conflicts of laws that would otherwise require the application of the law of any other state.

(p) EACH PARTY HEREBY WAIVES ITS RESPECTIVE RIGHTS TO A TRIAL BY JURY OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OR RELATED TO THIS SUBSCRIPTION AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY IN ANY ACTION, PROCEEDING OR OTHER LITIGATION OF ANY TYPE BROUGHT BY ANY PARTY AGAINST ANY OTHER PARTY OR ANY AFFILIATE OF ANY OTHER SUCH PARTY, WHETHER WITH RESPECT TO CONTRACT CLAIMS, TORT CLAIMS OR OTHERWISE. THE PARTIES AGREE THAT ANY SUCH CLAIM OR CAUSE OF ACTION SHALL BE TRIED BY A COURT TRIAL WITHOUT A JURY. WITHOUT LIMITING THE FOREGOING, THE PARTIES FURTHER AGREE THAT THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY IS WAIVED BY OPERATION OF THIS SECTION AS TO ANY ACTION, COUNTERCLAIM OR OTHER PROCEEDING WHICH SEEKS, IN WHOLE OR IN PART, TO CHALLENGE THE VALIDITY OR ENFORCEABILITY OF THIS SUBSCRIPTION AGREEMENT OR ANY PROVISION HEREOF. THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS SUBSCRIPTION AGREEMENT.

(q) The parties agree that all disputes, legal actions, suits and proceedings arising out of or relating to this Subscription Agreement must be brought exclusively in the Court of Chancery of the State of Delaware and any state appellate court therefrom within the State of Delaware (or, if the Court of Chancery of the State of Delaware declines to accept jurisdiction over a particular matter, any federal court within the State of Delaware or, in the event each federal court within the State of Delaware declines to accept jurisdiction over a particular matter, any state court within the State of Delaware) (collectively the “Designated Courts”). Each party hereby consents and submits to the exclusive jurisdiction of the Designated Courts. No legal action, suit or proceeding with respect to this Subscription Agreement may be brought in any other forum.

WHEREAS, the Company and Subscriber are executing and delivering this Subscription Agreement in reliance upon the exemption from securities registration afforded by Section 4(a)(2) of the Securities Act of 1933, as amended (the “1933 Act”), and Rule 506(b) of Regulation D (“Regulation D”) as promulgated by the Commission under the 1933 Act;

WHEREAS, pursuant to this Subscription Agreement, and in full satisfaction of the amounts due to Subscriber upon the consummation of the Transactions pursuant to its engagement by SPAC as set forth in the Engagement Letter, Subscriber shall receive from the Company, immediately prior to the consummation of the Transactions, that number of shares of Common Stock equal to the result of (x) 240,000 divided by (y) the Exchange Ratio (as defined in the Business Combination Agreement), as set forth on the signature page hereto (the “Subscribed Shares”), all on the terms and subject to the conditions set forth herein.

NOW, THEREFORE, in consideration of the foregoing and the mutual representations, warranties and covenants, and subject to the conditions, herein contained, and intending to be legally bound hereby, the parties hereto hereby agree as follows:

(ii) there shall have been no amendment or modification to the Business Combination Agreement after the date hereof that materially and adversely affects the Company or SPAC or the Subscriber’s investment in the Company or SPAC, other than amendments, waivers or modifications as expressly contemplated by and included in the terms of the Business Combination Agreement as of the date of its execution.

3

(g) Prior to or at the Closing, Subscriber shall deliver to the Company all such other information as is reasonably requested in order for the Company to issue the Subscribed Shares to Subscriber, including, without limitation, the legal name of the person in whose name the Subscribed Shares are to be issued (or Subscriber’s nominee in accordance with its delivery instructions) and a duly completed and executed Internal Revenue Service Form W-9 or appropriate Form W-8.

Section 4. Company and SPAC Representations and Warranties. The Company and SPAC each, severally and not jointly, represents and warrants to the Subscriber that, as of the date hereof and as of the Closing Date:

Each of the Company, SPAC and their respective Subsidiaries (as defined below) are entities duly organized and validly existing and in good standing under the laws of the jurisdiction in which they are formed, and have the requisite power and authority to own their properties and to carry on their business as now being conducted and as presently proposed to be conducted. Each of the Company, SPAC and each of their respective Subsidiaries is duly qualified as a foreign entity to do business and is in good standing in every jurisdiction in which its ownership of property or the nature of the business conducted by it makes such qualification necessary, except to the extent that the failure to be so qualified or be in good standing would not reasonably be expected to have a Material Adverse Effect (as defined below). As used in this Subscription Agreement, “Material Adverse Effect” means any material adverse effect on (i) the business, properties, assets, liabilities, operations (including results thereof), condition (financial or otherwise) or prospects of the Company, the SPAC or any of their respective Subsidiaries, individually or taken as a whole, (ii) the transactions contemplated hereby or in any of the other Transaction Documents or any other agreements or instruments to be entered into in connection herewith or therewith or (iii) the authority or ability of the Company, the SPAC or any of their respective Subsidiaries to perform any of their respective obligations under any of the Transaction Documents (as defined below). Other than the Persons (as defined below) set forth on Schedule 4(a), the Company and SPAC have no Subsidiaries. No Subsidiary of the Company owns any Intellectual Property that is material to the Company’s business or any other material assets. “Subsidiaries” means any Person in which the Company or the SPAC, as applicable, directly or indirectly, (I) owns any of the outstanding capital stock or holds any equity or similar interest of such Person or (II) controls or operates all or any part of the business, operations or administration of such Person, and each of the foregoing, is individually referred to herein as a “Subsidiary.”

(b) Authorization; Enforcement; Validity. The Company and SPAC each has the requisite power and authority to enter into and perform its obligations under this Subscription Agreement and the other Transaction Documents and the Company has the requisite power and authority to issue the Subscribed Shares in accordance with the terms hereof and thereof. The execution and delivery of this Subscription Agreement and the other Transaction Documents by the Company and the SPAC, and the consummation by the Company and the SPAC of the transactions contemplated hereby and thereby (including, without limitation, the issuance by the Company of the Subscribed Shares) have been duly authorized by the Company’s board of directors and SPAC’s board of directors, respectively, and (other than the filing with the SEC of the Business Combination Registration Statement, a Form D with the SEC and any other filings as may be required by any state securities agencies) no further filing, consent or authorization is required by the Company, the SPAC, their respective Subsidiaries, or their respective boards of directors or their stockholders or other governing body. This Subscription Agreement has been, and the other Transaction Documents to which it is a party will be prior to the Closing, duly executed and delivered by the Company and SPAC and each constitutes the legal, valid and binding obligations of the Company and SPAC, respectively, enforceable against the Company and SPAC in accordance with its respective terms, except as such enforceability may be limited by general principles of equity or applicable

As of the Closing, the Company shall have reserved from its duly authorized capital stock not less than the number of shares sufficient to cover the issuance of Subscribed Shares. The Subscribed Shares, when issued, will be validly issued, fully paid and nonassessable and free from all preemptive or similar rights or Liens with respect to the issue thereof, with the holders being entitled to all rights accorded to a holder of Common Stock. Subject to the accuracy of the representations and warranties of Subscriber in this Subscription Agreement, the offer and issuance by the Company of the Subscribed Shares is exempt from registration under the 1933 Act.

(d) No Conflicts. The execution, delivery and performance of the Transaction Documents by the Company and SPAC and the consummation by the Company and SPAC of the transactions contemplated hereby and thereby (including, without limitation, the issuance by the Company of the Subscribed Shares) will not (i) result in a violation of the Certificate of Incorporation (as defined below) (including, without limitation, any certificate of designation contained therein), Bylaws (as defined below), certificate of formation, memorandum of association, articles of association, bylaws or other organizational documents of the Company or the SPAC, or any capital stock or other securities of the Company or the SPAC, (ii) conflict with, or constitute a default (or an event which with notice or lapse of time or both would become a default) in any respect under, or give to others any rights of termination, amendment, acceleration or cancellation of, any agreement, indenture or instrument to which the Company or SPAC is a party, or (iii) result in a violation of any law, rule, regulation, order, judgment or decree (including, without limitation, foreign, federal and state securities laws and regulations and the rules and regulations of the Nasdaq Global Market LLC (the “Principal Market”) and including all applicable foreign, federal and state laws, rules and regulations) applicable to the Company or SPAC or by which any property or asset of the Company or the SPAC is bound or affected.

(e) Consents.

All consents, authorizations, orders, filings and registrations which the Company, SPAC or any of their respective Subsidiaries is required to obtain pursuant to the preceding sentence have been or will be obtained or effected on or prior to the Closing Date, and neither the Company, nor SPAC, nor any of their respective Subsidiaries, is aware of any facts or circumstances which might prevent the Company, SPAC or any of their respective Subsidiaries from obtaining or effecting any of the registration, application or filings contemplated by the Transaction Documents. “Governmental Entity” means any nation, state, county, city, town, village, district, or other political jurisdiction of any nature, federal, state, local, municipal, foreign, or other government, governmental or quasi-governmental authority of any nature (including any governmental agency, branch, department, official, or entity and any court or other tribunal), multi-national organization or body; or body exercising, or entitled to exercise, any administrative, executive, judicial, legislative, police, regulatory, or taxing authority or power of any nature or instrumentality of any of the foregoing, including any entity or enterprise owned or controlled by a government or a public international organization or any of the foregoing.

Neither the Company, nor any of its Subsidiaries or affiliates, nor any Person acting on its or their behalf, has engaged in any form of general solicitation or general advertising (within the meaning of Regulation D) in connection with the offer or sale of the Subscribed Shares. The Company shall be responsible for the payment of any placement agent’s fees, financial advisory fees, or brokers’ commissions (other than for Persons engaged by Subscriber or its investment advisor) relating to or arising out of the transactions contemplated hereby. The Company shall pay and hold Subscriber harmless against, any liability, loss or expense (including, without limitation, attorney’s fees and out-of-pocket expenses) arising in connection with any such claim. Neither the Company, nor SPAC, nor any of their respective Subsidiaries has engaged any placement agent or other agent in connection with the offer or sale of the Subscribed Shares.

(h) No Integrated Offering. None of the Company, SPAC or their respective Subsidiaries or any of their affiliates, nor any Person acting on their behalf has, directly or indirectly, made any offers or sales of any security or solicited any offers to buy any security, under circumstances that would require registration of the issuance of any of the Subscribed Shares under the 1933 Act, whether through integration with prior offerings or otherwise, or cause this offering of the Subscribed Shares to require approval of stockholders of the Company or stockholders of SPAC for purposes of the 1933 Act or under any applicable stockholder approval provisions, including, without limitation, under the rules and regulations of any exchange or automated quotation system on which any of the securities of the Company or SPAC are listed or designated for quotation. None of the Company, SPAC or any of their Subsidiaries, their affiliates nor any Person acting on their behalf will take any action or steps that would cause the offering of any of the Subscribed Shares to be integrated with other offerings of securities of the Company.

(i) [Reserved.]

(j) Application of Takeover Protections; Rights Agreement. The Company, SPAC and their respective boards of directors have taken all necessary action, if any, in order to render inapplicable any control share acquisition, interested stockholder, business combination, poison pill (including, without limitation, any distribution under a rights agreement), stockholder rights plan or other similar anti-takeover provision under the Certificate of Incorporation, Bylaws or other organizational documents or the laws of the jurisdiction of its incorporation or otherwise which is or could become applicable to Subscriber as a result of the transactions contemplated by this Subscription Agreement, including, without limitation, the Company’s issuance of the Subscribed Shares and Subscriber’s ownership of the Subscribed Shares. The Company, SPAC and their respective boards of directors have taken all necessary action, if any, in order to render inapplicable any stockholder rights plan or similar arrangement relating to accumulations of beneficial ownership of shares of Common Stock or a change in control of the Company or any of its Subsidiaries.

6

(k) SEC Documents; Financial Statements. The Company has delivered or has made available to Subscriber or their respective representatives true, correct and complete copies of each of the reports, schedules, forms, proxy statements, statements and other documents required to be filed by it with the SEC pursuant to the reporting requirements of the 1934 Act (all of the foregoing filed prior to the date hereof and all exhibits and appendices included therein and financial statements, notes and schedules thereto and documents incorporated by reference therein being hereinafter referred to as the “SEC Documents”) not available on the EDGAR system. As of their respective dates, the SEC Documents complied in all material respects with the requirements of the 1934 Act and the rules and regulations of the SEC promulgated thereunder applicable to the SEC Documents, and none of the SEC Documents, at the time they were filed with the SEC, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. As of their respective dates, the financial statements of the Company and SPAC included in the SEC Documents complied in all material respects with applicable accounting requirements and the published rules and regulations of the SEC with respect thereto as in effect as of the time of filing. Such financial statements have been prepared in accordance with generally accepted accounting principles (“GAAP”), consistently applied, during the periods involved (except (i) as may be otherwise indicated in such financial statements or the notes thereto, or (ii) in the case of unaudited interim statements, to the extent they may exclude footnotes or may be condensed or summary statements) and fairly present in all material respects the financial position of the Company and SPAC as of the dates thereof and the results of its operations and cash flows for the periods then ended (subject, in the case of unaudited statements, to normal year-end audit adjustments which will not be material, either individually or in the aggregate). The reserves, if any, established by the Company or the lack of reserves, if applicable, are reasonable based upon facts and circumstances known by the Company on the date hereof and there are no loss contingencies that are required to be accrued by the Statement of Financial Accounting Standard No. 5 of the Financial Accounting Standards Board which are not provided for by the Company in its financial statements or otherwise. No other information provided by or on behalf of the Company to Subscriber which is not included in the SEC Documents (including, without limitation, information referred to in Section 3(g) of this Subscription Agreement or in the disclosure schedules to this Subscription Agreement) contains any untrue statement of a material fact or omits to state any material fact necessary in order to make the statements therein not misleading, in the light of the circumstance under which they are or were made. The Company and SPAC are not currently contemplating to amend or restate any of the financial statements (including, without limitation, any notes or any letter of the independent accountants of the Company with respect thereto) included in the SEC Documents (with respect to each of the Company and SPAC, the “Financial Statements”), nor is the Company currently aware of facts or circumstances which would require the Company to amend or restate any of the Financial Statements, in each case, in order for any of the Financials Statements to be in compliance with GAAP and the rules and regulations of the SEC. Neither the Company nor SPAC has been informed by its independent accountants that they recommend that the Company or SPAC amend or restate any of the Financial Statements or that there is any need for the Company or SPAC to amend or restate any of the Financial Statements.

(l) Absence of Certain Changes. Since the date of the Company’s and SPAC’s most recent audited financial statements contained in the Business Combination Registration Statement, there has been no material adverse change and no material adverse development in the business, assets, liabilities, properties, operations (including results thereof), condition (financial or otherwise) or prospects of the Company, SPAC or any of their respective Subsidiaries. Since the date of the Company’s and SPAC’s most recent audited financial statements contained in a Business Combination Registration Statement, neither the Company, nor SPAC, nor any of their respective Subsidiaries has (i) declared or paid any dividends, (ii) sold any assets, individually or in the aggregate, outside of the ordinary course of business

7

or (iii) made any capital expenditures, individually or in the aggregate, outside of the ordinary course of business. Neither the Company, SPAC, nor any of their respective Subsidiaries has taken any steps to seek protection pursuant to any law or statute relating to bankruptcy, insolvency, reorganization, receivership, liquidation or winding up, nor does the Company, SPAC or any of their respective Subsidiaries have any knowledge or reason to believe that any of their respective creditors intend to initiate involuntary bankruptcy proceedings or any actual knowledge of any fact which would reasonably lead a creditor to do so. The Company, SPAC and their respective Subsidiaries, individually and on a consolidated basis, are not as of the date hereof, and after giving effect to the transactions contemplated hereby to occur at the Closing, will not be Insolvent (as defined below). For purposes of this Section 4(l), “Insolvent” means, (i) with respect to the Company, SPAC and their respective Subsidiaries, on a consolidated basis, (A) the present fair saleable value of the Company’s, SPAC’s and their respective Subsidiaries’ assets is less than the amount required to pay the Company’s, SPAC’s, and their respective Subsidiaries’ total Indebtedness (as defined below), (B) the Company, SPAC and their respective Subsidiaries are unable to pay their debts and liabilities, subordinated, contingent or otherwise, as such debts and liabilities become absolute and matured or (C) the Company, SPAC and their respective Subsidiaries intend to incur or believe that they will incur debts that would be beyond their ability to pay as such debts mature; and (ii) with respect to the Company, SPAC and each Subsidiary, individually, (A) the present fair saleable value of the Company’s, SPAC’s or such Subsidiary’s (as the case may be) assets is less than the amount required to pay its respective total Indebtedness, (B) the Company, SPAC or such Subsidiary (as the case may be) is unable to pay its respective debts and liabilities, subordinated, contingent or otherwise, as such debts and liabilities become absolute and matured or (C) the Company, SPAC or such Subsidiary (as the case may be) intends to incur or believes that it will incur debts that would be beyond its respective ability to pay as such debts mature. Neither the Company, nor SPAC, nor any of their respective Subsidiaries has engaged in any business or in any transaction, and is not about to engage in any business or in any transaction, for which the Company’s, SPAC’s or such Subsidiary’s remaining assets constitute unreasonably small capital with which to conduct the business in which it is engaged as such business is now conducted and is proposed to be conducted.

(m) No Undisclosed Events, Liabilities, Developments or Circumstances. No event, liability, development or circumstance has occurred or exists, or is reasonably expected to exist or occur with respect to the Company, SPAC, any of their respective Subsidiaries or any of their respective businesses, properties, liabilities, prospects, operations (including results thereof) or condition (financial or otherwise), that (i) would be required to be disclosed by the Company or SPAC under applicable securities laws and which has not been publicly announced, (ii) could have a material adverse effect on Subscriber’s investment hereunder or (iii) could have a Material Adverse Effect.

(n) Conduct of Business; Regulatory Permits. Neither the Company, nor SPAC nor any of their respective Subsidiaries is in violation of any term of or in default under its Certificate of Incorporation, any certificate of designation, preferences or rights of any other outstanding series of preferred stock of the Company, SPAC or any of their Subsidiaries or Bylaws or their organizational charter, certificate of formation, memorandum of association, articles of association, Certificate of Incorporation or certificate of incorporation or bylaws, respectively. Neither the Company, nor SPAC nor any of their respective Subsidiaries is in violation of any judgment, decree or order or any statute, ordinance, rule or regulation applicable to the Company, SPAC or any of their respective Subsidiaries, and neither the Company, nor SPAC nor any of their respective Subsidiaries will conduct its business in violation of any of the foregoing, except in all cases for possible violations which could not, individually or in the aggregate, have a Material Adverse Effect. Without limiting the generality of the foregoing, each of the Company and SPAC has no knowledge of any facts or circumstances that could reasonably lead to failure to list the Exchange Securities on the Principal Market upon consummation of the Transactions on the Principal Market. The Company, SPAC and each of their respective Subsidiaries possess all certificates, authorizations and permits issued by the appropriate regulatory authorities necessary to conduct their respective businesses, except where the

The Company, SPAC and each of their respective Subsidiaries are insured by insurers of recognized financial responsibility against such losses and risks and in such amounts as management of the Company and management of SPAC each believes to be prudent and customary in the businesses in which the Company, SPAC and their respective Subsidiaries are engaged. Neither the Company, nor SPAC nor any such Subsidiary has been refused any insurance coverage sought or applied for, and neither the Company, nor SPAC nor any such Subsidiary has any reason to believe that it will be unable to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business at a cost that would not have a Material Adverse Effect.

(v) Employee Relations. Neither the Company, nor SPAC nor any of their respective Subsidiaries is a party to any collective bargaining agreement or employs any member of a union.

12

terminate such officer’s employment with the Company, SPAC or any such Subsidiary.

The Company, SPAC and their respective Subsidiaries are in compliance with all federal, state, local and foreign laws and regulations respecting labor, employment and employment practices and benefits, terms and conditions of employment and wages and hours, except where failure to be in compliance would not, either individually or in the aggregate, reasonably be expected to result in a Material Adverse Effect.

The Company and its Subsidiaries own or possess adequate rights or licenses to use all trademarks, trade names, service marks, service mark registrations, service names, original works of authorship, patents, patent rights, copyrights, inventions, licenses, approvals, governmental authorizations, trade secrets and other intellectual property rights and all applications and registrations therefor (“Intellectual Property Rights”) necessary to conduct their respective businesses as now conducted and presently proposed to be conducted. Each of patents owned by the Company or any of its Subsidiaries is listed on Schedule 4(x)(i). Except as set forth in Schedule 4(x)(ii), none of the Company’s Intellectual Property Rights have expired or terminated or have been abandoned or are expected to expire or terminate or are expected to be abandoned, within three years from the date of this Subscription Agreement. The Company does not have any knowledge of any infringement by the Company or its Subsidiaries of Intellectual Property Rights of others. There is no claim, action or proceeding being made or brought, or to the knowledge of the Company or any of its Subsidiaries, being threatened, against the Company or any of its Subsidiaries regarding its Intellectual Property Rights. Neither the Company nor any of its Subsidiaries is aware of any facts or circumstances which might give rise to any of the foregoing infringements or claims, actions or proceedings. The Company and its Subsidiaries have taken reasonable security measures to protect the secrecy, confidentiality and value of all of their Intellectual Property Rights.

The term “Environmental Laws” means all federal, state, local or foreign laws relating to pollution or protection of human health or the environment (including, without limitation, ambient air, surface water, groundwater, land surface or subsurface strata), including, without limitation, laws relating to emissions, discharges, releases or threatened releases of chemicals, pollutants, contaminants, or toxic or hazardous substances or wastes (collectively, “Hazardous Materials”) into the environment, or otherwise relating to the manufacture, processing, distribution, use, treatment, storage, disposal, transport or handling of Hazardous Materials, as well as all authorizations, codes, decrees, demands or demand letters, injunctions, judgments, licenses, notices or notice letters, orders, permits, plans or regulations issued, entered, promulgated or approved thereunder.

(B) are present on, over, beneath, in or upon any Real Property or any portion thereof in quantities that would constitute a violation of any Environmental Laws. No prior use by the Company or any of its Subsidiaries of any Real Property has occurred that violates any Environmental Laws, which violation would have a material adverse effect on the business of the Company or any of its Subsidiaries.

(iii) Neither the Company nor any of its Subsidiaries knows of any other person who or entity which has stored, treated, recycled, disposed of or otherwise located on any Real Property any Hazardous Materials, including, without limitation, such substances as asbestos and polychlorinated biphenyls.

There are no unpaid taxes in any material amount claimed to be due by the taxing authority of any jurisdiction, and the officers of the Company, SPAC and their respective

14

Subsidiaries know of no basis for any such claim. Each of the Company and SPAC is not operated in such a manner as to qualify as a passive foreign investment company, as defined in Section 1297 of the Code. The net operating loss carryforwards (“NOLs”) for United States federal income tax purposes of the consolidated group of which the Company and SPAC is the common parent, if any, shall not be adversely effected by the transactions contemplated hereby.

(bb) Internal Accounting and Disclosure Controls. The Company, SPAC and each of their respective Subsidiaries maintains internal control over financial reporting (as such term is defined in Rule 13a-15(f) under the 1934 Act) that is effective to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles, including that (i) transactions are executed in accordance with management’s general or specific authorizations, (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain asset and liability accountability, (iii) access to assets or incurrence of liabilities is permitted only in accordance with management’s general or specific authorization and (iv) the recorded accountability for assets and liabilities is compared with the existing assets and liabilities at reasonable intervals and appropriate action is taken with respect to any difference.

Neither the Company, nor SPAC, nor any of their respective Subsidiaries has received any notice or correspondence from any accountant, Governmental Entity or other Person relating to any potential material weakness or significant deficiency in any part of the internal controls over financial reporting of the Company, SPAC or any of their respective Subsidiaries.

(cc) Off Balance Sheet Arrangements. There is no transaction, arrangement, or other relationship between the Company, SPAC or any of their respective Subsidiaries and an unconsolidated or other off balance sheet entity that is required to be disclosed by the Company or SPAC in its 1934 Act filings and is not so disclosed or that otherwise could be reasonably likely to have a Material Adverse Effect.

(vv) Cybersecurity. The Company and its Subsidiaries’ information technology assets and equipment, computers, systems, networks, hardware, software, websites, applications, and databases (collectively, “IT Systems”) are adequate for, and operate and perform in all material respects as required in connection with the operation of the business of the Company and its Subsidiaries as currently conducted, free and clear of all material bugs, errors, defects, Trojan horses, time bombs, malware and other corruptants that would reasonably be expected to have a Material Adverse Effect on the Company’s business. The Company and its Subsidiaries have implemented and maintained commercially reasonable physical, technical and administrative controls, policies, procedures, and safeguards to maintain and protect their material confidential information and the integrity, continuous operation, redundancy and security of all IT Systems and data, including “Personal Data,” used in connection with their businesses. “Personal Data” means (i) a natural person’s name, street address, telephone number, e-mail address, photograph, social security number or tax identification number, driver’s license number, passport number, credit card number, bank information, or customer or account number; (ii) any information which would qualify as “personally identifying information” under the Federal Trade Commission Act, as amended; (iii) “personal data” as defined by the European Union General Data Protection Regulation (“GDPR”) (EU 2016/679); (iv) any information which would qualify as “protected health information” under the Health Insurance Portability and Accountability Act of 1996, as amended by the Health Information Technology for Economic and Clinical Health Act (collectively, “HIPAA”); and (v) any other piece of information that allows the identification of such natural person, or his or her family, or permits the collection or analysis of any data related to an identified person’s health or sexual orientation. There have been no breaches, violations, outages or unauthorized uses of or accesses to same, except for those that have been remedied without material cost or liability or the duty to notify any other person or such, nor any incidents under internal review or investigations relating to the same except in each case, where such would not, either individually or in the aggregate, reasonably be expected to result in a Material Adverse Effect. The Company and its Subsidiaries are presently in compliance with all applicable laws or statutes and all judgments, orders, rules and regulations of any court or arbitrator or governmental or regulatory authority, internal policies and contractual obligations relating to the privacy and security of IT Systems and Personal Data and to the protection of such IT Systems and Personal Data from unauthorized use, access, misappropriation or modification except in each case, where such would not, either individually or in the aggregate, reasonably be expected to result in a Material Adverse Effect.

(ww) Compliance with Data Privacy Laws. The Company and its Subsidiaries are, and at all prior times were, in compliance with all applicable state and federal data privacy and security laws and regulations, including without limitation HIPAA, and the Company and its Subsidiaries have taken commercially reasonable actions to prepare to comply with, and since May 25, 2018, have been and currently are in compliance with, the GDPR (EU 2016/679) (collectively, the “Privacy Laws”) except in each case, where such would not, either individually or in the aggregate, reasonably be expected to result in a Material Adverse Effect. To ensure compliance with the Privacy Laws, the Company and its Subsidiaries have in place, comply with, and take appropriate steps reasonably designed to ensure

19

compliance in all material respects with their policies and procedures relating to data privacy and security and the collection, storage, use, disclosure, handling, and analysis of Personal Data (the “Policies”). The Company and its Subsidiaries have at all times made all disclosures to users or customers required by applicable laws and regulatory rules or requirements, and none of such disclosures made or contained in any Policy have, to the knowledge of the Company, been inaccurate or in violation of any applicable laws and regulatory rules or requirements in any material respect. The Company further certifies that neither it nor any Subsidiary: (i) has received notice of any actual or potential liability under or relating to, or actual or potential violation of, any of the Privacy Laws, and has no knowledge of any event or condition that would reasonably be expected to result in any such notice; (ii) is currently conducting or paying for, in whole or in part, any investigation, remediation, or other corrective action pursuant to any Privacy Law; or (iii) is a party to any order, decree, or agreement that imposes any obligation or liability under any Privacy Law.

(xx) Disclosure. Each of the Company and SPAC confirms that neither it nor any other Person acting on its behalf has provided Subscriber or its agents or counsel with any information that constitutes or could reasonably be expected to constitute material, non-public information concerning the Company, SPAC or any of their respective Subsidiaries, other than the existence of the transactions contemplated by this Subscription Agreement and the other Transaction Documents. Each of the Company and SPAC understands and confirms that Subscriber will rely on the foregoing representations in effecting transactions in securities of the Company. All disclosure provided to Subscriber regarding the Company, SPAC and their respective Subsidiaries, their businesses and the transactions contemplated hereby, including the schedules to this Subscription Agreement, furnished by or on behalf of the Company, SPAC or any of their respective Subsidiaries is true and correct and does not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading. All of the written information furnished after the date hereof by or on behalf of the Company, SPAC or any of their respective Subsidiaries to Subscriber pursuant to or in connection with this Subscription Agreement and the other Transaction Documents, taken as a whole, will be true and correct in all material respects as of the date on which such information is so provided and will not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading. Each press release issued by the Company, SPAC or any of their respective Subsidiaries during the twelve (12) months preceding the date of this Subscription Agreement did not at the time of release contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they are made, not misleading. No event or circumstance has occurred or information exists with respect to the Company, SPAC or any of their respective Subsidiaries or its or their business, properties, liabilities, prospects, operations (including results thereof) or conditions (financial or otherwise), which, under applicable law, rule or regulation, requires public disclosure at or before the date hereof or announcement by the Company or SPAC but which has not been so publicly disclosed. All financial projections and forecasts that have been prepared by or on behalf of the Company, SPAC or any of their respective Subsidiaries and made available to Subscriber have been prepared in good faith based upon reasonable assumptions and represented, at the time each such financial projection or forecast was delivered to Subscriber, the Company’s or SPAC’s best estimate of future financial performance (it being recognized that such financial projections or forecasts are not to be viewed as facts and that the actual results during the period or periods covered by any such financial projections or forecasts may differ from the projected or forecasted results). The Company and SPAC each acknowledges and agrees that no Subscriber makes or has made any representations or warranties with respect to the transactions contemplated hereby other than those specifically set forth in Section 5.

20

Section 5. Subscriber Representations and Warranties. Subscriber represents and warrants to the Company and SPAC that, as of the date hereof and as of the Closing Date:

(a) Organization; Authority. Subscriber is an entity duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization with the requisite power and authority to enter into and to consummate the transactions contemplated by the Transaction Documents to which it is a party and otherwise to carry out its obligations hereunder.

(b) No Public Sale or Distribution. Subscriber is acquiring the Subscribed Shares for its own account and not with a view towards, or for resale in connection with, the public sale or distribution thereof in violation of applicable securities laws, except pursuant to sales registered or exempted under the 1933 Act; provided, however, by making the representations herein, Subscriber does not agree, or make any representation or warranty, to hold any of the Subscribed Shares for any minimum or other specific term and reserves the right to dispose of the Subscribed Shares at any time in accordance with or pursuant to a registration statement or an exemption from registration under the 1933 Act. Subscriber does not presently have any agreement or understanding, directly or indirectly, with any Person to distribute any of the Subscribed Shares in violation of applicable securities laws. For purposes of this Subscription Agreement, “Person” means an individual, a limited liability company, a partnership, a joint venture, a corporation, a trust, an unincorporated organization, any other entity and any Governmental Entity (as defined below) or any department or agency thereof.

(c) Accredited Investor Status. Subscriber is an “accredited investor” as that term is defined in Rule 501(a) of Regulation D, satisfying the applicable requirements set forth on Annex A hereto, and has provided the Company with the requested information on Annex A following the signature page hereto.

(d) Reliance on Exemptions. Subscriber understands that the Subscribed Shares are being offered and sold to it in reliance on specific exemptions from the registration requirements of United States federal and state securities laws and that the Company is relying in part upon the truth and accuracy of, and Subscriber’s compliance with, the representations, warranties, agreements, acknowledgments and understandings of Subscriber set forth herein in order to determine the availability of such exemptions and the eligibility of Subscriber to acquire the Subscribed Shares.

(e) Information. Subscriber and its advisors, if any, have been furnished with all materials relating to the business, finances and operations of the Company and materials relating to the offer and sale of the Subscribed Shares that have been requested by Subscriber. Subscriber and its advisors, if any, have been afforded the opportunity to ask questions of the Company. Neither such inquiries nor any other due diligence investigations conducted by Subscriber or its advisors, if any, or its representatives shall modify, amend or affect Subscriber’s right to rely on the Company’s representations and warranties contained herein. Subscriber understands that its investment in the Subscribed Shares involves a high degree of risk. Subscriber has sought such accounting, legal and tax advice as it has considered necessary to make an informed investment decision with respect to its acquisition of the Subscribed Shares.

(f) No Governmental Review. Subscriber understands that no United States federal or state agency or any other government or governmental agency has passed on or made any recommendation or endorsement of the Subscribed Shares or the fairness or suitability of the investment in the Subscribed Shares nor have such authorities passed upon or endorsed the merits of the offering of the Subscribed Shares.

(g) Transfer or Resale. Subscriber understands that: (i) the Subscribed Shares have not been registered under the 1933 Act or any state securities laws, and may not be offered for sale, sold, assigned or transferred unless (A) subsequently registered, or (B) Subscriber provides the Company with reasonable assurance that such Subscribed Shares can be sold, assigned or transferred pursuant to Rule 144 or Rule 144A promulgated under the 1933 Act (or a successor rule thereto) (collectively, “Rule 144”); and (ii) any

21

sale of the Subscribed Shares made in reliance on Rule 144 may be made only in accordance with the terms of Rule 144, and further, if Rule 144 is not applicable, any resale of the Subscribed Shares under circumstances in which the seller (or the Person through whom the sale is made) may be deemed to be an underwriter (as that term is defined in the 1933 Act) may require compliance with some other exemption under the 1933 Act or the rules and regulations of the SEC promulgated thereunder. Notwithstanding the foregoing, the Exchange Securities to be received by Subscriber upon consummation of the Transactions in exchange for the Subscribed Shares shall be registered under the 1933 Act and freely tradeable immediately following consummation of the Transactions, and the Subscribed Shares may be pledged in connection with a bona fide margin account or other loan or financing arrangement secured by the Subscribed Shares and such pledge of Subscribed Shares shall not be deemed to be a transfer, sale or assignment of the Subscribed Shares hereunder, and no Subscriber effecting a pledge of Subscribed Shares shall be required to provide the Company with any notice thereof or otherwise make any delivery to the Company pursuant to this Subscription Agreement, including, without limitation, this Section 5(g).

(h) Validity; Enforcement. This Subscription Agreement has been duly and validly authorized, executed and delivered on behalf of Subscriber and shall constitute the legal, valid and binding obligations of Subscriber enforceable against Subscriber in accordance with their respective terms, except as such enforceability may be limited by general principles of equity or to applicable bankruptcy, insolvency, reorganization, moratorium, liquidation and other similar laws relating to, or affecting generally, the enforcement of applicable creditors’ rights and remedies.

(i) No Conflicts. The execution, delivery and performance by Subscriber of this Subscription Agreement and the consummation by Subscriber of the transactions contemplated hereby will not (i) result in a violation of the organizational documents of Subscriber, or (ii) conflict with, or constitute a default (or an event which with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, any agreement, indenture or instrument to which Subscriber is a party, or (iii) result in a violation of any law, rule, regulation, order, judgment or decree (including federal and state securities laws) applicable to Subscriber, except in the case of clauses (ii) and (iii) above, for such conflicts, defaults, rights or violations which could not, individually or in the aggregate, reasonably be expected to have a material adverse effect on the ability of Subscriber to perform its obligations hereunder.

Section 6. Register; Transfer Agent Instructions; Legend.

(a) Register. The Company shall maintain at its principal executive offices (or such other office or agency of the Company as it may designate by notice to each holder of Subscribed Shares), a stock ledger for the Subscribed Shares in which the Company shall record the name and address of the Person in whose name the Subscribed Shares have been issued (including the name and address of each transferee) and the number of Subscribed Shares held by such Person. The Company shall keep the stock ledger open and available at all times during business hours for inspection of Subscriber or its legal representatives. If Subscriber effects a sale, assignment or transfer of the Subscribed Shares in accordance with Section 5(g), the Company shall permit the transfer and shall promptly record in its stock ledger for the Subscribed Shares, such name and such denominations as specified by Subscriber to effect such sale, transfer or assignment.

(b) Transfer Agent Instructions. Upon the consummation of the Transactions, the SPAC shall issue irrevocable instructions to its transfer agent and any subsequent transfer agent (as applicable, the “Transfer Agent”) in a form acceptable to Subscriber (the “Irrevocable Transfer Agent Instructions”) to issue certificates or credit shares to the applicable balance accounts at The Depository Trust Company (“DTC”), registered in the name of Subscriber or its respective nominee(s), for the Exchange Securities in such amounts as in accordance with the terms of the Business Combination Agreement. The SPAC represents and warrants that no instruction other than the Irrevocable Transfer Agent Instructions referred

22

to in this Section 6(b) will be given by the SPAC to the Transfer Agent with respect to the Exchange Securities, and that the Exchange Securities shall otherwise be freely transferable on the books and records of the SPAC to the extent provided in this Subscription Agreement and the Business Combination Agreement. In the event that a sale, assignment or transfer involves Exchange Securities sold, assigned or transferred pursuant to an effective registration statement or in compliance with Rule 144, and the Transfer Agent has not already issued the Exchange Securities as credit shares to the applicable balance accounts at DTC, the Transfer Agent shall issue such shares to such Subscriber, assignee or transferee (as the case may be) without any restrictive legend in accordance with Section 6(d) below. Each of the Company and SPAC acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to Subscriber. Accordingly, each of the Company and SPAC acknowledges that the remedy at law for a breach of its obligations under this Section 6(b) will be inadequate and agrees, in the event of a breach or threatened breach by the Company of the provisions of this Section 6(b), that Subscriber shall be entitled, in addition to all other available remedies, to an order and/or injunction restraining any breach and requiring immediate issuance and transfer, without the necessity of showing economic loss and without any bond or other security being required. The SPAC shall cause its counsel to issue the legal opinion referred to in the Irrevocable Transfer Agent Instructions to the Transfer Agent following the consummation of the Transactions. Any fees (with respect to the Transfer Agent, counsel to the Company or SPAC or otherwise) associated with the issuance of such opinion or the removal of any legends on any of the Subscribed Shares or the Exchange Securities shall be borne by the Company and SPAC, jointly.

(c) Legends. Subscriber understands that the Subscribed Shares have been issued pursuant to an exemption from registration or qualification under the 1933 Act and applicable state securities laws, and except as set forth below, the Subscribed Shares shall bear any legend as required by the “blue sky” laws of any state and a restrictive legend in substantially the following form (and a stop-transfer order may be placed against transfer of such stock certificates):

THE ISSUANCE AND SALE OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (I) IN THE ABSENCE OF (A) AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR (B) AN OPINION OF COUNSEL TO THE HOLDER (IF REQUESTED BY THE COMPANY), IN A FORM REASONABLY ACCEPTABLE TO THE COMPANY, THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR (II) UNLESS SOLD OR ELIGIBLE TO BE SOLD PURSUANT TO RULE 144 OR RULE 144A UNDER SAID ACT. NOTWITHSTANDING THE FOREGOING, THE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN OR FINANCING ARRANGEMENT SECURED BY THE SECURITIES.

(d) Removal of Legends. Upon the closing of the Transactions, in accordance with the terms of the Business Combination Agreement, the Exchange Securities shall be issued without any legends. The SPAC shall no later than two (2) trading days following the closing of the Transactions, either: (A) provided that the Transfer Agent is participating in the DTC Fast Automated Securities Transfer Program (“FAST”), credit the aggregate number of shares of SPAC Common Stock to which Subscriber shall be entitled as Exchange Securities to Subscriber’s or its designee’s balance account with DTC through its Deposit/Withdrawal at Custodian system or (B) if the Transfer Agent is not participating in FAST, issue and deliver (via reputable overnight courier) to Subscriber, a certificate representing such shares of SPAC Common Stock that is free from all restrictive and other legends, registered in the name of Subscriber or its designee (the date by which such credit is so required to be made to the balance account of Subscriber or Subscriber’s designee with DTC or such certificate is required to be delivered to Subscriber pursuant to

23

the foregoing is referred to herein as the “Required Delivery Date”, and the date such shares of SPAC Common Stock are actually delivered without restrictive legend to Subscriber or Subscriber’s designee with DTC, as applicable, the “Share Delivery Date”). The SPAC shall be responsible for any Transfer Agent fees or DTC fees with respect to any issuance of Exchange Securities or the removal of any legends with respect to any Exchange Securities in accordance herewith.

(e) FAST Compliance. While any Subscribed Shares remain outstanding, SPAC shall maintain a transfer agent that participates in FAST.

Section 7. Termination. This Subscription Agreement shall terminate and be void and of no further force and effect, and all rights and obligations of the parties hereunder shall terminate without any further liability on the part of any party in respect thereof, upon the earliest to occur of (a) such date and time as the Business Combination Agreement is terminated in accordance with its terms and (b) the mutual written agreement of the parties hereto to terminate this Subscription Agreement; provided, that if any of the conditions to the obligations of Subscriber and the Company to consummate, or cause to be consummated, the transactions contemplated by this Subscription Agreement (including the Closing) set forth in Sections 3(d), (e) or (f) are not satisfied on the Closing Date, this Subscription Agreement shall be terminable by any of the Company or Subscriber upon written notice of termination delivered in accordance with Section 9(a); provided further, that nothing herein will relieve any party from liability for any willful breach hereof prior to the time of termination, and each party will be entitled to any remedies at law or in equity to recover losses, liabilities or damages arising from such breach. The Company shall notify Subscriber of the termination of the Business Combination Agreement promptly after the termination thereof. Upon the termination hereof in accordance with this Section 7, any monies paid by Subscriber to the Company in connection herewith shall promptly (and in any event within one Business Day) be returned in full to Subscriber by wire transfer of U.S. dollars in immediately available funds to the account specified by Subscriber, without any deduction for or on account of any tax withholding, charges or set-off, whether or not the Transactions shall have been consummated.

Section 8. Trust Account Waiver. Subscriber hereby acknowledges that, as described in SPAC’s prospectus relating to its initial public offering (the “IPO”) dated September 23, 2021 available at www.sec.gov, SPAC has established a trust account (the “Trust Account”) containing the proceeds of the IPO and from certain private placements occurring simultaneously with the IPO (including interest accrued from time to time thereon) for the benefit of SPAC, its public shareholders and certain other parties (including the underwriters of the IPO), and that, except as otherwise described in such prospectus, SPAC may disburse monies from the Trust Account only to (x) its public shareholders in the event they elect to have their shares of SPAC Common Stock redeemed for cash in connection with the consummation of SPAC’s initial business combination, an amendment to its certificate of incorporation, as amended and rested and as in effect on the date hereof (the “SPAC Charter”) to extend the deadline by which SPAC must consummate its initial business combination, or SPAC’s failure to consummate an initial business combination by such deadline, (y) pay certain taxes from time to time, or (z) SPAC after or concurrently with the consummation of its initial business combination. For and in consideration of SPAC entering into this Subscription Agreement, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Subscriber, on behalf of itself and its affiliates, hereby (a) agrees that it does not now and shall not at any time hereafter have any right, title, interest or claim of any kind in or to any assets held in the Trust Account, and shall not make any claim against the Trust Account, arising out or as a result of, in connection with or relating in any way to this Subscription Agreement, and regardless of whether such claim arises based on contract, tort, equity or any other theory of legal liability (any and all such claims are collectively referred to hereafter as the “Released Claims”), (b) irrevocably waives any Released Claims that it may have against the Trust Account now or in the future as a result of, or arising out of, this Subscription Agreement, and (c) will not seek recourse against the Trust Account as a result of, in connection with or relating in any way to this Subscription Agreement. Subscriber acknowledges and agrees that such irrevocable waiver is a material inducement to SPAC to enter into this Subscription

24

Agreement, and further intends and understands such waiver to be valid, binding, and enforceable against Subscriber in accordance with applicable law. To the extent Subscriber commences any action or proceeding based upon, in connection with, relating to or arising out of any matter relating to SPAC or its Representatives, which proceeding seeks, in whole or in part, monetary relief against SPAC or its Representatives, Subscriber hereby acknowledges and agrees that its sole remedy shall be against funds held outside of the Trust Account and that such claim shall not permit Subscriber (or any person claiming on Subscriber’s behalf or in lieu of Subscriber) to have any claim against the Trust Account (including any distributions therefrom) or any amounts contained therein. Nothing in this Section 8 shall be deemed to limit Subscriber’s right to distributions from the Trust Account in accordance with the SPAC Charter, in respect of any redemptions by Subscriber in respect of shares of SPAC Common Stock. Notwithstanding anything in this Subscription Agreement to the contrary, the provisions of this Section 8 shall survive termination of this Subscription Agreement.

Section 9. Miscellaneous.

Notwithstanding the foregoing, Subscriber may assign all or a portion of its rights and obligations under this Subscription Agreement to one or more of its affiliates (including other investment funds or accounts managed or advised by the investment manager who acts on behalf of Subscriber) upon written notice to the Company and SPAC or, with the Company’s and SPAC’s prior written consent, to another person; provided, that in the case of any such assignment, the assignee(s) shall become a Subscriber hereunder and have the rights and obligations and be deemed to make the representations and warranties of Subscriber provided for herein to the extent of such assignment and provided further that no such assignment shall relieve the assigning Subscriber of its obligations hereunder if any such assignee fails to perform such obligations, unless the Company and SPAC have given their prior written consent to such relief.

(i) This Subscription Agreement constitutes the entire agreement, and supersedes all other prior agreements, understandings, representations and warranties, both written and oral, among the parties, with respect to the subject matter hereof.

(j) Except as otherwise provided herein, this Subscription Agreement is intended for the benefit of the parties hereto and their heirs, executors, administrators, successors, legal representatives, and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other person. Except as set forth in Section 6, Section 8, Section 9(b), Section 9(c), Section 9(e), Section 9(h) and this Section 9(j) with respect to the persons specifically referenced therein, this Subscription Agreement shall not confer any rights or remedies upon any person other than the parties hereto, and their respective successors and assigns.

(k) The parties hereto acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Subscription Agreement were not performed in accordance with their specific terms or were otherwise breached and that money or other legal remedies would not be an adequate remedy for such damage. It is accordingly agreed that the parties shall be entitled to equitable relief, including in the form of an injunction or injunctions to prevent breaches or threatened breaches of this Subscription Agreement and to enforce specifically the terms and provisions of this Subscription Agreement, this being in addition to any other remedy to which such party is entitled at law, in equity, in contract, in tort or otherwise. The parties hereto acknowledge and agree that the Company shall be entitled

26

to specifically enforce Subscriber’s obligations to fund the Subscription and the provisions of the Subscription Agreement, in each case, on the terms and subject to the conditions set forth herein. The parties hereto further acknowledge and agree: (x) to waive any requirement for the security or posting of any bond in connection with any such equitable remedy; (y) not to assert that a remedy of specific enforcement pursuant to this Section 9(k) is unenforceable, invalid, contrary to applicable law or inequitable for any reason; and (z) to waive any defenses in any action for specific performance, including the defense that a remedy at law would be adequate.

(l) If any provision of this Subscription Agreement shall be invalid, illegal or unenforceable, the validity, legality or enforceability of the remaining provisions of this Subscription Agreement shall not in any way be affected or impaired thereby and shall continue in full force and effect.

(m) No failure or delay by a party hereto in exercising any right, power or remedy under this Subscription Agreement, and no course of dealing between the parties hereto, shall operate as a waiver of any such right, power or remedy of such party. No single or partial exercise of any right, power or remedy under this Subscription Agreement by a party hereto, nor any abandonment or discontinuance of steps to enforce any such right, power or remedy, shall preclude such party from any other or further exercise thereof or the exercise of any other right, power or remedy hereunder. The election of any remedy by a party hereto shall not constitute a waiver of the right of such party to pursue other available remedies. No notice to or demand on a party not expressly required under this Subscription Agreement shall entitle the party receiving such notice or demand to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the party giving such notice or demand to any other or further action in any circumstances without such notice or demand.

(n) This Subscription Agreement may be executed and delivered in one or more counterparts (including by electronic mail, in .pdf or other electronic submission) and by different parties in separate counterparts, with the same effect as if all parties hereto had signed the same document. All counterparts so executed and delivered shall be construed together and shall constitute one and the same agreement.

(o) This Subscription Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, without regard to the principles of conflicts of laws that would otherwise require the application of the law of any other state.

(p) EACH PARTY HEREBY WAIVES ITS RESPECTIVE RIGHTS TO A TRIAL BY JURY OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OR RELATED TO THIS SUBSCRIPTION AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY IN ANY ACTION, PROCEEDING OR OTHER LITIGATION OF ANY TYPE BROUGHT BY ANY PARTY AGAINST ANY OTHER PARTY OR ANY AFFILIATE OF ANY OTHER SUCH PARTY, WHETHER WITH RESPECT TO CONTRACT CLAIMS, TORT CLAIMS OR OTHERWISE. THE PARTIES AGREE THAT ANY SUCH CLAIM OR CAUSE OF ACTION SHALL BE TRIED BY A COURT TRIAL WITHOUT A JURY. WITHOUT LIMITING THE FOREGOING, THE PARTIES FURTHER AGREE THAT THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY IS WAIVED BY OPERATION OF THIS SECTION AS TO ANY ACTION, COUNTERCLAIM OR OTHER PROCEEDING WHICH SEEKS, IN WHOLE OR IN PART, TO CHALLENGE THE VALIDITY OR ENFORCEABILITY OF THIS SUBSCRIPTION AGREEMENT OR ANY PROVISION HEREOF. THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS SUBSCRIPTION AGREEMENT.

27

(q) The parties agree that all disputes, legal actions, suits and proceedings arising out of or relating to this Subscription Agreement must be brought exclusively in the Court of Chancery of the State of Delaware and any state appellate court therefrom within the State of Delaware (or, if the Court of Chancery of the State of Delaware declines to accept jurisdiction over a particular matter, any federal court within the State of Delaware or, in the event each federal court within the State of Delaware declines to accept jurisdiction over a particular matter, any state court within the State of Delaware) (collectively the “Designated Courts”). Each party hereby consents and submits to the exclusive jurisdiction of the Designated Courts. No legal action, suit or proceeding with respect to this Subscription Agreement may be brought in any other forum. Notwithstanding the foregoing, a final judgement in any such action may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Each party hereby irrevocably waives all claims of immunity from jurisdiction, and any objection which such party may now or hereafter have to the laying of venue of any suit, action or proceeding in any Designated Court, including any right to object on the basis that any dispute, action, suit or proceeding brought in the Designated Courts has been brought in an improper or inconvenient forum or venue. Each of the parties also agrees that delivery of any process, summons, notice or document to a party hereof in compliance with Section 9(a) of this Subscription Agreement shall be effective service of process for any action, suit or proceeding in a Designated Court with respect to any matters to which the parties have submitted to jurisdiction as set forth above.

(r) This Subscription Agreement may only be enforced against, and any claim, action, suit or other legal proceeding based upon, arising out of, or related to this Subscription Agreement, or the negotiation, execution or performance of this Subscription Agreement, may only be brought against the entities that are expressly named as parties hereto.

(s) The Company shall, by 9:00 a.m., New York City time, on the first Business Day immediately following the date of this Subscription Agreement, file with the Commission a Current Report on Form 8-K (the “Disclosure Document”) disclosing all material terms of this Subscription Agreement and the transactions contemplated hereby, the Transactions and any other material, nonpublic information that the Company or SPAC has provided to Subscriber at any time prior to the filing of the Disclosure Document and including as exhibits to the Disclosure Document, the form of this Subscription Agreement (without redaction). Upon the issuance of the Disclosure Document, to the Company’s knowledge, Subscriber shall not be in possession of any material, non-public information received from the Company or SPAC or any of its affiliates, officers, directors, or employees or agents, unless otherwise agreed by Subscriber. Notwithstanding anything in this Subscription Agreement to the contrary, each of the Company and SPAC (i) shall not publicly disclose the name of Subscriber or any of its affiliates or advisers, or include the name of Subscriber or any of its affiliates or advisers in any press release, without the prior written consent of Subscriber and (ii) shall not publicly disclose the name of Subscriber or any of its affiliates or advisers, or include the name of Subscriber or any of its affiliates or advisers in any filing with the Commission or any regulatory agency or trading market, without the prior written consent of Subscriber, except (A) as required by the federal securities laws, rules or regulations and (B) to the extent such disclosure is required by other laws, rules or regulations, at the request of the staff of the Commission or regulatory agency or under the regulations of the Stock Exchange, in which case of clause (A) or (B), the Company and SPAC, as applicable, shall provide Subscriber with prior written notice (including by e-mail) of such permitted disclosure, and shall reasonably consult with Subscriber regarding such disclosure. Subscriber will promptly provide any information reasonably requested by the Company and SPAC for any regulatory application or filing made or approval sought in connection with the Transactions (including filings with the Commission).

(t) If any change in the Common Stock shall occur between the date of this Subscription Agreement and the Closing by reason of any reclassification, recapitalization, stock split, reverse stock split, combination, exchange, or readjustment of shares, or any share dividend, the number of Subscribed Shares issued to Subscriber hereunder shall be appropriately adjusted to reflect such change.

28

(u) The headings herein are for convenience only, do not constitute a part of this Subscription Agreement and shall not be deemed to limit or affect any of the provisions hereof. The language used in this Subscription Agreement will be deemed to be the language chosen by the parties hereto to express their mutual intent, and no rules of strict construction will be applied against any party. Unless the context otherwise requires, (i) all references to Sections, Schedules or Exhibits are to Sections, Schedules or Exhibits contained in or attached to this Subscription Agreement, (ii) each accounting term not otherwise defined in this Subscription Agreement has the meaning assigned to it in accordance with GAAP, (iii) words in the singular or plural include the singular and plural and pronouns stated in either the masculine, the feminine or neuter gender shall include the masculine, feminine and neuter, (iv) the use of the word “including” in this Subscription Agreement shall be by way of example rather than limitation, and (v) the word “or” shall not be exclusive.
