Section 5. Subscriber Representations and Warranties. Subscriber represents and warrants to the Company, as of the date hereof and as of the Closing Date, that: (a) Subscriber (i) is duly organized or incorporated and validly existing and in good standing under the laws of the jurisdiction of its organization or incorporation; and (ii) has all corporate or other organizational power and authority to execute, deliver and perform its obligations under this Subscription Agreement.

(c) Subscriber has the power, capacity and authority, and the legal right, to make, deliver and perform this Subscription Agreement. Assuming the due execution and delivery of this Agreement by the Company, this Subscription Agreement constitutes a legal, valid and binding obligation of Subscriber, enforceable against Subscriber in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors’ rights generally and by general equitable principles (whether enforcement is sought by proceedings in equity or at law).
6 (d) Subscriber is acquiring the Subscribed Shares for its own account, for investment purposes only and not with a view to any distribution thereof that would not otherwise comply with the Securities Act (and has provided the Company with the requested information on Annex A hereto). (e) Subscriber understands that (i) the Subscribed Shares have not been registered under the Securities Act and the Subscribed Shares are being issued by the Company in transactions exempt from the registration requirements of the Securities Act, and (ii) all or any part of the Subscribed Shares may not be offered or sold except pursuant to effective registration statements under the Securities Act or pursuant to applicable exemptions from registration under the Securities Act and in compliance with applicable state Laws. (f) Subscriber understands that the exemption from registration afforded by Rule 144 promulgated under the Securities Act (“Rule 144”) (the provisions of which are known to the Subscriber) depends on the satisfaction of various conditions, and that, if applicable, Rule 144 may afford the basis for sales only in limited amounts. (g) Subscriber did not employ any broker or finder in connection with the transactions contemplated in this Subscription Agreement and no fees or commissions are payable to the Subscriber, except as otherwise expressly provided for in this Subscription Agreement. (h) No portion of the funds or assets that will be used by Subscriber to pay the Purchase Price or to acquire or hold the Subscribed Shares, constitute or will constitute the assets of any (i) employee benefit plan subject to Title I of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), (ii) plan described in and subject to Section 4975 of the Code (each such employee benefit plan and plan described in clauses (i) and (ii) referred to herein as an “ERISA Plan”), (iii) plan, account or other arrangement subject to provisions under any other federal, state, local, non-U.S. or other laws or regulations that are similar to the fiduciary responsibility or prohibited transaction provisions of Title I of ERISA or Section 4975 of the Code that could cause the underlying assets of the Company to be treated as assets of such plan, account or arrangement or (iv) entity whose underlying assets are deemed to include “plan assets” of any such ERISA Plan or Similar Law Plan pursuant to Section 3(42) of ERISA and any regulations that may be promulgated thereunder or otherwise. (i) No filing with, or authorization, approval, consent, license, order, registration, qualification or decree of, any Governmental Authority or third party is necessary or required by or with respect to Subscriber for the execution of this Subscription Agreement by Subscriber or the consummation by the Subscriber of the transactions contemplated herein. (j) None of the execution, delivery or performance by Subscriber of this Subscription Agreement nor the consummation by Subscriber of the transactions contemplated herein will conflict with, violate or constitute a breach of or a default under (i) Subscriber’s or any of its Subsidiaries’ Organizational Documents, (ii) any indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument to which Subscriber is a party or by which Subscriber is bound or to which any of the property or assets of Subscriber is subject; or (iii) any Applicable Law binding upon Subscriber or any of its Subsidiaries, except in the case of clauses (ii) and (iii) as would not, individually or in the aggregate, reasonably be expected to enjoin, prevent or delay the consummation by Subscriber of the transactions contemplated herein. (k) Subscriber is in compliance with all Applicable Laws, writs, injunctions and orders, except to the extent that failure to do so would not reasonably be expected to have, individually or in the aggregate, a material adverse effect on the Subscriber’s ability to perform its obligation hereunder.
7 (l) Subscriber has substantial investment experience so that Subscriber has the capacity to protect its own interests and is fully capable of evaluating the merits and risks of its purchase of the Subscribed Shares. Subscriber acknowledges that it has made its own decision to purchase the Subscribed Shares without reliance on any representation or warranty of the Company or any third party (other than with respect to the representations and warranties expressly set forth in Section 4). Subscriber further acknowledges that neither the Company nor any other party has any responsibility with respect to any statements, representations or warranties that have been made or may be made in connection with the transactions contemplated by this Subscription Agreement regarding the Company, or the value of the Subscribed Shares and that neither the Company nor any other party has made any representation, warranty or covenant, express or implied, to Subscriber in connection with the transactions contemplated herein (other than with respect to the representations and warranties expressly set forth in Section 4). Specifically, the Company has not made any representation, warranty or covenant, express or implied, with respect to the Company’s business, financial condition, prospects, or value, or the value of the Subscribed Shares. Subscriber represents that it has had a full, fair and complete opportunity to value the Subscribed Shares. Subscriber acknowledges that there is a limited trading market for the Common Stock and that the Purchase Price may not be indicative of the actual fair market value of the Subscribed Shares. Subscriber further acknowledges that the value of the Subscribed Shares may increase or decrease substantially over time. In full understanding of the possibility that, at the present time or in the future, the Subscribed Shares could be worth substantially more or less than the Purchase Price, Subscriber has voluntarily entered into this Subscription Agreement and determined to purchase the Subscribed Shares. (m) Subscriber has (i) had access to all information regarding the Company and its present and prospective business, assets, liabilities and financial condition that Subscriber considers important in making the decision to acquire the Subscribed Shares and (ii) had an opportunity to ask questions of and receive answers from the Company regarding the Company, its present and prospective business, assets, liabilities and financial condition and the terms and conditions of the Subscription. Subscriber acknowledges that the Company may be in possession of material, non-public information not known to the Subscriber (the “Excluded Information”). The Excluded Information, if publicly disclosed, could foreseeably affect the value of the Subscribed Shares, including Excluded Information that may be indicative that the value of such securities is substantially greater or lower than the purchase price being paid for such securities by the Subscriber as set forth herein. Notwithstanding the Company’s possession of the Excluded Information which is not being disclosed to Subscriber, the Subscriber wishes to enter into this Subscription Agreement at this time for its own business purposes. Subscriber understands the disadvantage to which Subscriber may be subject on account of the disparity of the access to, and possession of, the information between the Company and such Subscriber. Subscriber has conducted an independent evaluation of the Company’s business and securities to determine whether to engage in the transactions contemplated by this Subscription Agreement and, notwithstanding the absence of access by Subscriber to the Excluded Information, the Subscriber is desirous of consummating such transactions. Subscriber acknowledges that certain matters comprising the Excluded Information may or may not materialize and Subscriber agrees that the Company shall not be obligated to disclose any Excluded Information or have any liability to the Subscriber with respect to any such non-disclosure. Subscriber understands and agrees that the Company makes no representation or warranty whatsoever with respect to the business, condition (financial or otherwise), properties, prospects, creditworthiness, status or affairs of the Company or with respect to the value of the Subscribed Shares, in each case other than as expressly set forth in Section 4. (n) Subscriber is entering into this Subscription Agreement freely and understands and expressly accepts and assumes the economic and market risk associated with purchasing the Subscribed Shares for the Purchase Price. Subscriber acknowledges specifically that a possibility of total loss exists.
8 (o) Subscriber understands and agrees that no federal or state agency has passed upon or endorsed the merits of the offering of the Subscribed Shares or made any findings or determination as to the fairness of this investment. (p) Neither Subscriber nor any Person acting on its behalf in connection with this Agreement is (i) the subject or target of any economic or financial sanctions or trade embargoes imposed, administered, or enforced from time to time by the United States, including the U.S. Treasury Department’s Office of Foreign Assets Control and the U.S. Department of State, United Nations, United Kingdom, European Union, or any EU member state (“Sanctions”), including any Person that is (A) named on the List of Specially Designated Nationals and Blocked Persons administered by OFAC or any similar Sanctions- related list administered or enforced by the United States, United Nations, United Kingdom, European Union, or any EU member state, (B) located, organized, or resident in a country, region, or territory which is itself the subject or target of any Sanctions (currently, the Crimea, so-called Donetsk People’s Republic, Kherson, so-called Luhansk People’s Republic, and Zaporizhzhia regions of Ukraine, Cuba, Iran, North Korea, and Syria), or (C) owned or controlled by, or acting on behalf of, any such Person or Persons described in the foregoing (A) or (B); (ii) designated by the U.S. Treasury Department as warranting special measures or as being of primary money laundering concern; or (iii) a non-U.S. shell bank or providing banking services indirectly to a non-U.S. shell bank. (q) No foreign person (as defined in 31 C.F.R. Part 800.224) in which the national or subnational governments of a single foreign state have a substantial interest (as defined in 31 C.F.R. Part 800.244) will acquire a substantial interest in the Company as a result of the purchase and sale of Subscribed Shares hereunder such that a declaration to the Committee on Foreign Investment in the United States would be mandatory under 31 C.F.R. Part 800.401, and no foreign person will have control (as defined in 31 C.F.R. Part 800.208) over the Company from and after the Closing as a result of the purchase and sale of Subscribed Shares hereunder. (r) Subscriber will have sufficient funds to pay the Purchase Price pursuant to Section 2 of this Subscription Agreement at the Closing. (s) Except as expressly disclosed in a Schedule 13D or Schedule 13G (or amendments thereto) filed by Subscriber with the Commission with respect to the beneficial ownership of the Company’s outstanding securities prior to the date hereof, if any, Subscriber is not currently (and at all times through Closing will refrain from being or becoming) a member of a “group” (within the meaning of Section 13(d)(3) or Section 14(d)(2) of the Exchange Act, or any successor provision), including any group acting for the purpose of acquiring, holding or disposing of equity securities of the Company (within the meaning of Rule 13d-5(b)(1) under the Exchange Act). Section 6. Other Agreements of the Parties. (a) (i) The Subscribed Shares may only be disposed of in compliance with state and federal securities laws. In connection with any transfer of Subscribed Shares other than (A) pursuant to an effective registration statement, (B) pursuant to Rule 144 or (C) to the Company, the Company may require the transferor thereof to provide to the Company an opinion of counsel selected by the transferor and reasonably acceptable to the Company, the form and substance of which opinion shall be reasonably satisfactory to the Company, to the effect that such transfer does not require registration of such transferred Subscribed Shares under the Securities Act. As a condition of transfer, any such transferee shall agree in writing to be bound by the terms of this Section 6(a), as applicable. Subscriber hereby covenants and agrees not to effect any sale or other
9 transfer of the Subscribed Shares other than (x) pursuant to the plan of distribution contained in a registration statement covering the resale of such Subscribed Shares, (y) in accordance with the provisions of Rule 144, or (z) in compliance with another exemption from registration under the Securities Act and applicable state securities laws. (ii) Subscriber agrees to the imprinting, so long as is required by this Section 6(a), of a legend on any of the Subscribed Shares in the following form: THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR THE SECURITIES LAWS OF ANY STATE AND MAY NOT UNDER ANY CIRCUMSTANCES BE SOLD, TRANSFERRED, OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT FOR SUCH SECURITIES UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS. (b) The Company shall use its reasonable best efforts to prepare and file a listing of additional shares notification form with The Nasdaq Stock Market (the “Stock Exchange”) in respect of the Subscribed Shares in the time and manner required by the Stock Exchange. (c) Without the prior affirmative written consent of the Subscriber (which may be given, withheld, conditioned or delayed in the sole and absolute discretion of the Subscriber), the Company shall not consummate any financing for its capital, other than as follows: (i) in connection with any issuance and sale of shares of Common Stock (or any instrument exchangeable for or convertible into Common Stock), either (A) to the Subscriber pursuant to Section 6(d) hereof or (B) after May 13, 2028; or (ii) in connection with the incurrence of any indebtedness or the issuance and sale of any shares of Preferred Stock (or any instrument exchangeable for or convertible into Preferred Stock), after May 13, 2029; provided that from and after May 13, 2029, this clause (ii) shall be deemed replaced with the following: “(ii) in connection with the incurrence of any indebtedness or the issuance and sale of any shares of Preferred Stock (or any instrument exchangeable for or convertible into Preferred Stock), unless: (A) at least 30 days prior to any such incurrence, issuance and sale to any purchaser (such purchaser, the “Proposed Purchaser”), the Company gives the Subscriber the right to purchase the Subscriber’s fully-diluted ownership percentage of such securities; and (B) the Company gives the Subscriber a right of last offer to acquire 100% of such securities; in each case, on the same terms and conditions as the bona fide terms offered by the Proposed Purchaser.” (d) Each of the Subscriber and the Company shall have the right from time to time (the “Put/Call Right” and, in the case of the Company with respect to purchase amounts above $10,000,000, the “Second Company Call Right”), upon written notice to the other (an “Additional Shares Purchase Notice”), to require the issuance and purchase of a number of additional shares of Common Stock (together with the Subscribed Shares, the “Shares”) at a purchase price per share equal to $10.00 for a purchase price of up to $20,000,000 at any time and from time to time prior to May 13, 2027; provided, however, that: (i) the Company shall not deliver any Additional Shares Purchase Notice if, after giving effect to such Additional Shares Purchase Notice and all other Additional Shares Purchase Notices delivered by the Company during the same calendar month, the aggregate purchase price of the additional shares of Common Stock to be purchased pursuant to all such Additional Shares Purchase Notices in such calendar month would exceed $10,000,000;
10 (ii) an Additional Shares Purchase Notice may only be delivered by the Company if, as of the date that such Additional Shares Purchase Notice is delivered, (A) no Liquidation Event shall have occurred and be continuing and (B) all representations and warranties of the Company contained in this Subscription Agreement shall be true and correct in all respects, mutatis mutandis, at and as of such date (except to the extent that any such representation or warranty expressly speaks as of an earlier date, in which case such representation or warranty shall be true and correct in all respects as of such earlier date), in each case, except where the failure to be so true and correct has not had, and would not reasonably be expected to have, a Material Adverse Effect; and (iii) no Additional Shares Purchase Notice with respect to a Second Company Call Right may be delivered by the Company unless the Company can establish that it had, in the ordinary course of business and as of the last day of the most recently ended calendar month, less than $40,000,000 of cash on its balance sheet, as determined by the Company in good faith and reflected in its internal books and records.

12 (h) This Subscription Agreement constitutes the entire agreement, and supersedes all other prior agreements, understandings, representations and warranties, both written and oral, between the Parties with respect to the subject matter hereof. (i) Except as otherwise provided herein, this Subscription Agreement is intended for the benefit of the Parties and their respective permitted heirs, executors, administrators, successors, legal representatives, and assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other Person. Except as set forth in this Section 7(i) 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, and their respective successors and assigns, and the Parties acknowledge that such Persons so referenced are third party beneficiaries of this Subscription Agreement for the purposes of, and to the extent of, the rights granted to them, if any, pursuant to the applicable provisions. (j) The Parties 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 acknowledge and agree that the Company shall be entitled to specifically enforce Subscriber’s obligations to fund the Purchase Price and the provisions of the Subscription Agreement, in each case, on the terms and subject to the conditions set forth herein. The Parties further acknowledge and agree: (i) to waive any requirement for the security or posting of any bond in connection with any such equitable remedy; (ii) not to assert that a remedy of specific enforcement pursuant to this Section 7(j) is unenforceable, invalid, contrary to Applicable Law or inequitable for any reason; and (iii) to waive any defenses in any action for specific performance, including the defense that a remedy at law would be adequate. (k) 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. (l) No failure or delay by either Party in exercising any right, power or remedy under this Subscription Agreement, and no course of dealing between the Parties, 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 either Party, 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 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. (m) This Subscription Agreement may be signed in counterparts (which may include counterparts delivered by any standard form of telecommunication), each of which shall be an original and all of which together shall constitute one and the same instrument.

Counterparts may be delivered via facsimile, electronic mail (including any electronic signature covered by the Electronic Signatures in Global and National Commerce Act of 2000, Uniform Electronic Transactions Act, the Electronic Signatures and Records Act or other Applicable Law (e.g., www.docusign.com)) or other transmission method and any counterpart so delivered shall be deemed to have been duly and validly delivered and be legally valid, effective and enforceable for all purposes. (n) This Subscription Agreement and any dispute or claim arising out of, or in connection with, it or its subject matter or formation (including non-contractual disputes or claims) shall be governed by and construed in accordance with the laws of the State of Delaware, without giving effect to any choice of law or conflict of law provision or rule that would cause the application of the laws of any jurisdiction other than the State of Delaware. Each Party hereby irrevocably submits to the exclusive jurisdiction of the Court of Chancery of the State of Delaware or, if such court does not have subject matter jurisdiction, any other state or federal court located in the State of Delaware, over any suit, action or other proceeding brought by either Party arising out of or relating to this Subscription Agreement, and each Party hereby irrevocably agrees that all claims or disputes with respect to any such suit, action or other proceeding shall be heard and determined in such courts. Each Party hereby consents to service of process in any such proceeding in any manner permitted by the Laws of Delaware, and further consents to service of process by nationally recognized overnight courier service guaranteeing overnight delivery, or by registered or certified mail, return receipt requested, at its address specified pursuant to Section 7(a).

EACH PARTY MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION 7(o) WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF EACH SUCH PARTY TO THE WAIVER OF ITS RIGHT TO TRIAL BY JURY.
