**Exhibit 10.4 **

**FORM OF SUBSCRIPTION AGREEMENT **

This **SUBSCRIPTION AGREEMENT **(this “Subscription Agreement”) is entered into on July 26, 2026 by and between RESEARCH ALLIANCE CORPORATION III, a Cayman Islands exempted company (the “Company”), and the subscriber party set forth on the signature page hereto (the “Subscriber”), acting severally and not jointly with any Other Subscriber (as defined below).

**RECITALS **

WHEREAS, substantially concurrently with the execution of this Subscription Agreement, the Company is entering into a business combination agreement (the “Business Combination Agreement”) with OHB Pediatrics Ltd., a company incorporated under the laws of England and Wales (“OHBP”), and such other holders of shares of OHBP party thereto and whose names are set out in Schedule 1a to the Business Combination Agreement (“OHBP Shareholders”), pursuant to which (and subject to the terms and conditions set forth therein), the Company will acquire OHBP and the OHBP Shareholders will sell their shares in the capital of OHBP to the Company in consideration for the issuance by the Company of shares of the Company’s common stock, par value $0.0001 per share (the “Common Stock”, and such acquisition, the “OHBP Share Acquisition”). After giving effect to the OHBP Share Acquisition, OHBP will be a wholly-owned subsidiary of the Company;

At least one day prior to the Closing Date (and as more fully described in the Business Combination Agreement), the Company will domesticate as a Delaware corporation in accordance with Section 388 of the General Corporation Law of the State of Delaware and Part XII of the Cayman Islands Companies Law (2020 Revision) (the “Domestication”, and together with the OHBP Share Acquisition and the other transactions contemplated by the Business Combination Agreement, the “Transactions”);

WHEREAS, in connection with the Transactions, Subscriber desires to subscribe for and purchase from the Company and the Company desires to issue and sell to Subscriber in consideration of the payment thereto, on the terms and subject to the conditions contained in this Subscription Agreement, following the Domestication and immediately prior to or substantially concurrently with the Closing, (A) that number of shares (the “Subscribed Shares”) of the Company’s common stock, par value $0.0001 per share (the “Common Stock”) at $10.00 per Subscribed Share (the “Per Share Price”), and/or (B) pursuant to Section 2 hereof, pre-funded warrants to purchase shares of Common Stock substantially in the form attached hereto as Exhibit A (the “Pre-Funded Warrants”), each to purchase one share of the Company’s common stock (collectively, the “Pre-Funded Warrant Shares”), with a per share exercise price equal to $0.0001 (the “Exercise Price”), at a purchase price per Pre-Funded Warrant equal to the Purchase Price less the Exercise Price, in the form of Exhibit A hereto, as set forth opposite such Subscriber’s name on the signature page hereto. The aggregate purchase price of the Subscribed Shares and the Pre-Funded Warrants shall be as set forth opposite such on Subscriber’s name on the signature page hereto next to the heading “Purchase Price”;

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 “Securities Act”); and

WHEREAS, concurrently with the execution of this Subscription Agreement, the Company is entering into subscription agreements (the “Other Subscription Agreements”) substantially similar to this Subscription Agreement with certain other investors (the “Other Subscribers”) pursuant to which each such Other Subscriber has agreed to purchase shares of Common Stock at the Closing (as defined below) at the same Per Share Price as the Subscriber.

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:

**AGREEMENT **

1. Subscription; No Fractional Shares. Subject to the terms and conditions hereof, at the Closing (as defined below), Subscriber, severally and not jointly with any Other Subscriber, hereby agrees to subscribe for and purchase from the Company, and the Company hereby agrees to issue and sell to Subscriber, upon the payment of the Purchase Price, (i) the Subscribed Shares and/or (ii) if applicable pursuant to Section 2 hereof, the Pre-Funded Warrants (such subscription and issuance, the “Subscription”). If Subscriber elects to receive Pre-Funded Warrants in lieu of all or a portion of the Subscribed Shares (which election shall be indicated on Subscriber’s signature page hereto), the aggregate purchase price payable by Subscriber shall remain unchanged and (a) the number of Subscribed Shares shall be reduced by the number of shares of Common Stock underlying the Pre-Funded Warrants issued to Subscriber and (b) Subscriber shall be issued Pre-Funded Warrants exercisable for such number of shares of Common Stock as is specified on Subscriber’s signature page hereto. Subscriber and the Company acknowledge that, as a result of the Domestication, the Subscribed Shares will be shares of Common Stock (and the Pre-Funded Warrants will be exercisable for shares of Common Stock) of the Company as a Delaware corporation and will not be ordinary shares of the Company as a Cayman Islands exempted company. No fractional shares of Common Stock shall be issued pursuant to this Subscription Agreement. The number of Subscribed Shares (and, if applicable, shares issuable upon exercise of the Pre-Funded Warrants) issued at the Closing shall be rounded down to the nearest whole number of shares of Common Stock.

2. Closing.

(a) The consummation of the Subscription contemplated hereby (the “Closing”) shall occur on the closing date of the OHBP Share Acquisition (the “Closing Date”), following the Domestication and immediately prior to or substantially concurrently with the consummation of the other Transactions and it is conditioned upon the satisfaction or waiver of the conditions set forth in this Section 2. If Subscriber has elected to receive Pre-Funded Warrants in lieu of all or a portion of the Subscribed Shares, references in this Section 2 to the delivery and issuance of Subscribed Shares shall be construed to include (as applicable) the delivery and issuance of Pre-Funded Warrants and, upon exercise thereof, Pre-Funded Warrant Shares.

(b) At least three (3) Business Days (as defined below) before the anticipated Closing Date, the Company shall deliver or cause to be delivered written notice to Subscriber (the “Closing Notice”) specifying (i) the anticipated Closing Date, (ii) the wire instructions for delivery of the Purchase Price to an escrow account (the “Escrow Account”) established by the Company with a third party escrow agent (the “Escrow Agent”) to be identified in the Closing Notice, (iii) the expected number of Subscribed Shares, and (iv) if applicable, the expected number of Pre-Funded Warrants to be issued to Subscriber. No later than two (2) Business Days prior to the anticipated Closing Date as set forth in the Closing Notice, Subscriber shall deliver the Purchase Price for the Subscribed Shares (and, if applicable, the Pre-Funded Warrants) by wire transfer of United States dollars in immediately available funds to the Escrow Account and deliver to the Company such information as is reasonably requested in the Closing Notice in order for the Company to issue the Subscribed Shares (and, if applicable, the Pre-Funded Warrants) to Subscriber, including, without limitation, the legal name of the person in whose name the Subscribed Shares (and, if applicable, the Pre-Funded Warrants) are to be issued and a duly completed and executed Internal Revenue Service Form W-9 or appropriate Form W-8 (and any required attachments thereto). Upon the Closing, the Company shall provide instructions to the Escrow Agent to release the funds in the Escrow Account to the Company. The Company shall deliver to Subscriber (i) at the Closing, (A) the Subscribed Shares, if any, in book entry form, free and clear of any liens or other restrictions (other than those arising under this Subscription Agreement or applicable securities laws), in the name of Subscriber (or its nominee in accordance with its delivery instructions), and (B) if applicable, Pre-Funded Warrants (substantially in the form attached hereto as Exhibit A) exercisable for the number of shares of Common Stock as set forth on Subscriber’s signature page hereto, and (ii) as promptly as practicable after the Closing, evidence from the Company’s transfer agent of the issuance to Subscriber of the Subscribed Shares (in book entry form), if any, on and as of the Closing Date. [Notwithstanding the foregoing three sentences, if Subscriber informs the Company (and it does so hereby inform the Company) (1) that it is an investment company registered

under the Investment Company Act of 1940, as amended (the “1940 Act”), (2) that it is advised by an investment adviser subject to regulation under the Investment Advisers Act of 1940, as amended, or (3) that its internal compliance policies and procedures so require it, then, in lieu of the settlement procedures in the foregoing three sentences, the following shall apply: Subscriber shall deliver as soon as practicable on the Closing Date (or as soon as practicable following receipt of evidence from the Company’s transfer agent of the issuance to Subscriber of the Subscribed Shares on and as of the Closing Date) the Purchase Price for the Subscribed Shares (and, if applicable, the Pre-Funded Warrants) by wire transfer of United States dollars in immediately available funds to an account to be specified by the Company against delivery by the Company to Subscriber of (A) the Subscribed Shares, if any, in book entry form, free and clear of any liens or other restrictions (other than those arising under this Subscription Agreement or applicable securities laws), in the name of Subscriber (or its nominee in accordance with its delivery instructions) and evidence from the Company’s transfer agent of the issuance to Subscriber of the Subscribed Shares on and as of the Closing Date, and (B) if applicable, Pre-Funded Warrants exercisable for the number of Pre-Funded Warrant Shares as set forth on Subscriber’s signature page hereto.] As promptly as practicable after the Closing, the Company shall provide Subscriber updated book-entry statements from the Company’s transfer agent reflecting the change in name of the Company to occur in connection with the Closing. In the event that the consummation of the Transactions does not occur within two (2) Business Days after the anticipated Closing Date specified in the Closing Notice, unless otherwise agreed to in writing by the Company and Subscriber, the Company shall promptly (but in no event later than three (3) Business Days after the anticipated Closing Date specified in the Closing Notice) instruct the Escrow Agent to return the Purchase Price to Subscriber by wire transfer in immediately available funds to the account specified by Subscriber (or, in the case of a Subscriber that has elected the alternate settlement provisions above, the Company shall return the Purchase Price so delivered by Subscriber to the Company), and any book entries or Pre-Funded Warrants delivered shall be deemed cancelled. Notwithstanding such return or cancellation (x) a failure to close on the anticipated Closing Date shall not, by itself, be deemed to be a failure of any of the conditions to Closing set forth herein, and (y) unless and until this Subscription Agreement is terminated in accordance with Section 6 herein, Subscriber shall remain obligated (A) to redeliver funds to the Escrow Account or to the Company, as applicable, in accordance with this Section 2 following the Company’s delivery to Subscriber of a new Closing Notice and (B) to consummate the Closing immediately prior to or substantially concurrently with the consummation of the Transactions. For the purposes of this Subscription Agreement, “Business Day” means any day other than a Saturday, Sunday or any other day on which commercial banks are required or authorized to close in the State of New York or the Cayman Islands.

(c) The Closing shall be subject to the satisfaction on the Closing Date, or written waiver by each of the parties hereto, of each of the following conditions:

(i) the Common Stock (including the Subscribed Shares and the Pre-Funded Warrant Shares) shall have been approved for listing on the Nasdaq Stock Market LLC (“Nasdaq”), subject only to official notice of issuance and no suspension of the qualification of the Common Stock for offering or sale or trading on Nasdaq and, to the knowledge of the Company, no initiation or threatening of any proceedings for any of such purposes or delisting, shall have occurred;

(ii) all conditions precedent to the closing of the Transactions set forth in the Business Combination Agreement, including all necessary approvals of the Company’s and OHBP’s shareholders and regulatory approvals, if any, shall have been satisfied (as determined by the parties to the Business Combination Agreement) or waived (other than those conditions which, by their nature, are to be satisfied only at the closing of the Transactions pursuant to the Business Combination Agreement), and the closing of the Transactions shall be scheduled to occur substantially concurrently with or immediately following the Closing; and

(iii) no governmental authority of competent jurisdiction shall have enacted, issued, promulgated, enforced or entered any judgment, order, law, rule or regulation (whether temporary, preliminary or permanent) which is then in effect and has the effect of making the consummation of the Transactions illegal or otherwise restraining, enjoining, or prohibiting consummation of the Transactions, and no such governmental authority shall have instituted or threatened in writing a proceeding seeking to impose any such restraint or prohibition.

(d) The obligation of the Company to consummate the Closing shall be subject to the satisfaction or written waiver by the Company of the additional conditions that, on the Closing Date:

(i) all representations and warranties of Subscriber contained in this Subscription Agreement shall be true and correct in all material respects (other than representations and warranties that are qualified as to materiality or Subscriber Material Adverse Effect (as defined below), which representations and warranties shall be true and correct in all respects) at and as of the Closing Date, except to the extent that any such representation and warranty expressly speaks as of an earlier date, in which case such representation and warranty shall be true and correct in all material respects (other than representations or warranties that are qualified as to materiality or Subscriber Material Adverse Effect, which representations or warranties shall be true and correct in all respects) as of such earlier date, in each case without giving effect to the consummation of the Transactions; and

(ii) Subscriber shall have performed, satisfied and complied in all material respects with all covenants, agreements and conditions required by this Subscription Agreement to be performed, satisfied or complied with by it at or prior to the Closing, except where the failure of such performance, satisfaction or compliance would not or would not reasonably be likely to prevent, materially delay, or materially impact the ability of the Company to consummate the Closing.

(e) The obligation of Subscriber to consummate the Closing shall be subject to the satisfaction or written waiver by Subscriber of the additional conditions that, on the Closing Date:

(i) except to the extent consented to in writing by Subscriber, the Business Combination Agreement shall not have been amended, modified, or supplemented, and no condition shall have been waived thereunder, in each case, in a manner that would reasonably be expected to materially and adversely affect the economic benefits that Subscriber (in its capacity as such) would reasonably expect to receive under this Subscription Agreement;

(ii) all representations and warranties of the Company contained in this Subscription Agreement shall be true and correct in all material respects (other than representations and warranties that are qualified as to materiality or Company Material Adverse Effect (as defined below), which representations and warranties shall be true and correct in all respects) at and as of the Closing Date (except to the extent that any such representation or warranty expressly speaks as of an earlier date, in which case such representation and warranty shall be true and correct in all material respects (other than representations and warranties that are qualified as to materiality or Company Material Adverse Effect, which representations and warranties shall be true and correct in all respects) as of such earlier date), in each case, without giving effect to the consummation of the Transactions;

(iii) no Other Subscription Agreement (or other agreements or understandings (including side letters) entered into in connection therewith or otherwise in connection with the sale of shares of Common Stock or Pre-Funded Warrants to any Other Subscriber pursuant to a Subscription Agreement) shall have been amended, modified or waived in any manner that benefits any Other Subscriber unless the Subscriber shall have been offered in writing substantially the same benefits (other than terms particular to the legal or regulatory requirements of such Other Subscriber or its affiliates or related persons);

(iv) all consents, waivers, authorizations or orders of, any notice required to be made to, and any filing or registration with, any court or other federal, state, local or other governmental authority, self-regulatory organization (including Nasdaq and any stockholder approval required by the rules and regulations of Nasdaq) or other person in connection with the execution, delivery and performance of this Subscription Agreement (including, without limitation, the issuance of the Subscribed Shares and the Pre-Funded Warrants, if any) required to be made in connection with the issuance and sale of the Subscribed Shares and the Pre-Funded Warrants, if any, shall have been obtained or made, except where the failure to so obtain or make would not prevent the Company from consummating the transactions contemplated hereby, including the issuance and sale of the Subscribed Shares and the Pre-Funded Warrants, if any, to the Subscriber;

(v) the Company shall have performed, satisfied and complied in all material respects with all covenants, agreements and conditions required by this Subscription Agreement to be performed, satisfied or complied with by it at or prior to the Closing, except where the failure of such performance, satisfaction or compliance would not or would not be reasonably likely to prevent, materially delay, or materially impact the ability of the Subscriber to consummate the Closing; and

(vi) there has not occurred any Material Adverse Effect or Parent Material Adverse Effect (each as defined in the Business Combination Agreement) since the date of this Subscription Agreement that is continuing.

(f) Prior to or at the Closing, Subscriber shall deliver or cause to be delivered to the Company all such other information as is reasonably requested and necessary in order for the Company to issue the Subscribed Shares and Pre-Funded Warrants, if any, to Subscriber.

3. Company Representations and Warranties. The Company represents and warrants to Subscriber that:

(a) The Company (i) is duly incorporated, validly existing as a company and in good standing under the laws of its jurisdiction of incorporation, (ii) has the requisite power and authority to own, lease and operate its properties, to carry on its business as it is now being conducted and to enter into, deliver and perform its obligations under this Subscription Agreement, the Other Subscription Agreements, the Pre-Funded Warrants and the Business Combination Agreement (collectively, the “Transaction Documents”), and (iii) is duly licensed or qualified to conduct its business and, if applicable, is in good standing under the laws of each jurisdiction (other than its jurisdiction of incorporation) in which the conduct of its business or the ownership of its properties or assets requires such license or qualification, except, with respect to the foregoing clause (iii), where the failure to be in good standing would not reasonably be expected to have a Company Material Adverse Effect. For purposes of this Subscription Agreement, a “Company Material Adverse Effect” means an event, change, development, occurrence, condition or effect with respect to the Company and its subsidiaries, taken together as a whole (on a consolidated basis), that, individually or in the aggregate, would reasonably be expected to have a material adverse effect on (i) the business, financial condition, or results of operations of the Company, (ii) the Company’s ability to consummate the transactions contemplated hereby, including the issuance and sale of the Subscribed Shares and Pre-Funded Warrants, or (iii) the Company’s ability to consummate the Transactions.

(b) As of the Closing Date, (i) the Subscribed Shares, if any, and (ii) the Pre-Funded Warrants, if any, will be duly authorized and, when issued and delivered to Subscriber against full payment therefor in accordance with the terms of this Subscription Agreement, will be validly issued, fully paid and non-assessable (in the case of the Subscribed Shares) or duly and validly authorized and binding obligations of the Company (in the case of the Pre-Funded Warrants), in each case free and clear of all liens or other restrictions (other than those arising under this Subscription Agreement or applicable federal and state securities laws) and will not have been issued in violation of or subject to any preemptive or similar rights created under the Company’s organizational documents (as adopted on or prior to the Closing Date) or the laws of its jurisdiction of incorporation. The shares of Common Stock issuable upon exercise of the Pre-Funded Warrants (the “Pre-Funded Warrant Shares”) have been duly and validly authorized and reserved for issuance and, upon issuance pursuant to the terms of the Pre-Funded Warrants against full payment therefor in accordance with the terms of the Pre-Funded Warrants, will be duly and validly issued, fully paid and non-assessable and will be issued free and clear of all liens or other restrictions (other than those arising under this Subscription Agreement or applicable federal and state securities laws), and the holder of the Pre-Funded Warrant Shares shall be entitled to all rights accorded to a holder of Common Stock. The issuance of the Pre-Funded Warrants does not, and the exercise in full of the Pre-Funded Warrants and the issuance and delivery of the Pre-Funded Warrant Shares thereupon will not, (a) obligate the Company to offer to issue, or issue, shares of Common Stock or other securities to any person (other than Subscriber) pursuant to any preemptive rights, rights of first refusal, rights of participation or similar rights or (b) result in any adjustment (automatic, at the election of any person or otherwise) of the exercise, conversion, exchange or reset price under, or any other anti-dilution adjustment pursuant to, any outstanding securities of the Company.

(c) Each of the Transaction Documents has been duly authorized, executed and delivered by the Company, and, assuming the due authorization, execution and delivery of the same by the applicable counterparties, each Transaction Document shall constitute the valid and legally binding obligation of the Company, enforceable against the Company in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and similar laws affecting the rights of creditors generally and by the availability of equitable remedies.

(d) The execution and delivery of the Transaction Documents, the performance by the Company of its obligations under this Subscription Agreement, the issuance and sale of the Subscribed Shares, if any, the issuance and sale of the Pre-Funded Warrants, if any, the issuance and delivery of the Pre-Funded Warrant Shares upon exercise in full of the Pre-Funded Warrants, if any, and the compliance by the Company with all of the provisions of this Subscription Agreement, the Pre-Funded Warrants and the consummation of the transactions contemplated herein will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition of any lien, charge or encumbrance upon any of the property or assets of the Company pursuant to the terms of (i) any indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument to which the Company is a party or by which the Company is bound or to which any of the property or assets of the Company is subject, (ii) the organizational documents of the Company, or (iii) assuming the accuracy of the representations and warranties of Subscriber in Section 4, any statute or any judgment, order, rule or regulation of any court or governmental agency or body, domestic or foreign, having jurisdiction over the Company or any of its properties that, in the case of clauses (i) and (iii), would reasonably be expected to have a Company Material Adverse Effect or materially affect the validity or enforceability of the Subscribed Shares, the Pre-Funded Warrants, the Pre-Funded Warrant Shares, or the ability or legal authority of the Company to comply in all material respects with this Subscription Agreement and the Pre-Funded Warrants (if any).

(e) Assuming the accuracy of the representations and warranties of Subscriber in Section 4, the Company is not required to obtain any consent, waiver, authorization or order of, give any notice to, or make any filing or registration with, any court or other federal, state, local or other governmental authority, self-regulatory organization (including Nasdaq) or other person in connection with the execution, delivery and performance by the Company of this Subscription Agreement (including, without limitation, the issuance of the Subscribed Shares or the Pre-Funded Warrants), other than (i) filings required by applicable federal and state securities laws, (ii) the filing of the Registration Statement (as defined below) with the Securities and Exchange Commission (the “Commission”) pursuant to Section 5 below, (iii) those required by Nasdaq, including with respect to obtaining shareholder approval, (iv) those required to consummate the Transactions as provided under the Business Combination Agreement, (v) the filing of notification under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, if applicable, in connection with the Transactions, and (vii) those of which the failure to obtain would not be reasonably expected to have, individually or in the aggregate, a Company Material Adverse Effect.

(f) Except for such matters as have not had or would not be reasonably expected to have a Company Material Adverse Effect, there is no (i) suit, action, claim or other proceeding or arbitration before a governmental authority or arbitrator pending, or, to the knowledge of the Company, threatened in writing against the Company or (ii) judgment, decree, injunction, ruling or order of any governmental authority or arbitrator outstanding against the Company.

(g) Assuming the accuracy of Subscriber’s representations and warranties set forth in Section 4 of this Subscription Agreement, no registration under the Securities Act is required for the offer and sale of the Subscribed Shares or the Pre-Funded Warrants by the Company to Subscriber, and, assuming the continued accuracy of such representations and warranties at the time of exercise, no registration under the Securities Act is required for the issuance of the Pre-Funded Warrant Shares upon exercise of the Pre-Funded Warrants.

(h) Neither the Company nor any person acting on its behalf has engaged or will engage in any form of general solicitation or general advertising (within the meaning of Regulation D under the Securities Act) in connection with any offer or sale of the Subscribed Shares or Pre-Funded Warrants. The Subscribed Shares and Pre-Funded Warrants are not being offered in a manner involving a public offering under, or in a distribution in violation of, the Securities Act or any state securities laws. Neither the Company nor any person acting on their behalf has, directly or indirectly, at any time within the past six months, made any offer or sale of any security or solicitation of any offer to buy any security under circumstances that would (i) eliminate the availability of the exemption from registration under Section 4(a)(2) under the Securities Act in connection with the offer and sale by the Company of the Subscribed Shares and Pre-Funded Warrants as contemplated hereby or (ii) cause the offering of the Subscribed Shares and Pre-Funded Warrants pursuant to this Subscription Agreement to be integrated with prior offerings by the Company for purposes of the Securities Act. Neither the Company nor any person acting on its behalf has offered or sold or will offer or sell any securities, or has taken or will take any other action, which would reasonably be expected to subject the offer, issuance or sale of the Subscribed Shares or the Pre-Funded Warrants, as contemplated hereby, to the registration provisions of the Securities Act.

(i) Except for Leerink Partners LLC, UBS Securities LLC, Wells Fargo Securities, LLC and LifeSci Capital LLC, and any additional placement agents engaged by the Company (collectively, the “Placement Agents”), no broker or finder is entitled to any brokerage or finder’s fee or commission solely in connection with the sale of the Subscribed Shares or Pre-Funded Warrants to Subscriber. The Company is solely responsible for the payment of any fees, costs, expenses and commissions owed to the Placement Agents in connection with the Subscription or the Transactions.

(j) (i) As of their respective dates, or if amended prior to the date of this Subscription Agreement, as of the date of such amendment, which shall be deemed to supersede such original filing, each report, form, statement, schedule, prospectus, proxy, registration statement and other document required to be filed by the Company with the Commission (such reports, the “SEC Reports”) complied in all material respects with the applicable requirements of the Securities Act and the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations of the Commission promulgated thereunder as in effect as of the time of filing; (ii) none of the SEC Reports, when filed, or if amended prior to the date of this Subscription Agreement, as of the date of such amendment, which shall be deemed to supersede such original filing, 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; (iii) the financial statements of the Company included in the SEC Reports, when filed, or, if amended, as of the date of such amendment, which shall be deemed to supersede such original filing, complied in all material respects with applicable accounting requirements and the rules and regulations of the Commission with respect thereto as in effect at the time of filing and fairly presented in all material respects the financial position of the Company as of and for the dates thereof and the results of operations and cash flows for the periods then ended, subject, in the case of unaudited statements, to normal, year-end audit adjustments; (iv) the Company has filed each report, statement, schedule, prospectus, and registration statement that the Company was required to file with the Commission since its initial registration of securities with the Commission through the date of this Subscription Agreement; and (v) there are no outstanding or unresolved comments in comment letters received by the Company from the staff of the Division of Corporation Finance of the Commission with respect to any of the SEC Reports. A copy of each SEC Report is available to Subscriber via the Commission’s EDGAR system.

(k) As of the date of this Subscription Agreement, the authorized capital stock of the Company consists of 1,000,000 preference shares (“Cayman Preferred Shares”), 479,000,000 Class A ordinary shares (“Cayman Class********* A Shares***”), and 20,000,000 Class B ordinary shares (the “Cayman Class********* B Shares***”), each par value $0.0001 per share. As of the date of this Subscription Agreement, (i) no Cayman Preferred Shares are issued and outstanding, (ii) 7,775,000 Cayman Class A Shares are issued and outstanding, of which 7,500,000 are redeemable Cayman Class A Shares and 275,000 are non-

The foregoing represents all of the issued and outstanding Company Securities as of the date of this Subscription Agreement. All issued and outstanding Company Securities (i) have been duly authorized and validly issued and are fully paid and non-assessable; (ii) have been offered, sold and issued in compliance with applicable law, including federal and state securities laws, and all requirements set forth in (1) the Company’s Amended and Restated Memorandum and Articles of Association, as amended from time to time (the “Company Constitutional Documents”), and (2) any other applicable contracts governing the issuance of such securities; and (iii) are not subject to, nor have they been issued in violation of, any purchase option, call option, right of first refusal, preemptive right, subscription right or any similar right under any provision of any applicable law, the Company Constitutional Documents or any contract to which the Company is a party or otherwise bound. Except as set forth above and pursuant to the Other Subscription Agreements, the Business Combination Agreement and the other agreements and arrangements referred to therein, as of the date hereof, there are no outstanding options, warrants or other rights to subscribe for, purchase or acquire from the Company any Company Securities or other equity interests in the Company or securities convertible into or exchangeable or exercisable for such equity interests. As of the date hereof, the Company has no subsidiaries, other than the subsidiaries formed to consummate the Transactions and such subsidiaries have not conducted any business since their date of formation, and does not own, directly or indirectly, interests or investments (whether equity or debt) in any person, whether incorporated or unincorporated.

(l) There are no securities issued by or to which the Company is a party containing anti-dilution or similar provisions that will be triggered by the issuance of the Subscribed Shares or the Common Stock to be issued pursuant to the Other Subscription Agreements, the issuance of the Pre-Funded Warrants, the issuance of the Pre-Funded Warrant Shares upon exercise of the Pre-Funded Warrants, or securities to be issued pursuant to the Business Combination Agreement, in each case, that have not been or will not be validly waived on or prior to the Closing Date.

(m) The Company is in compliance with all applicable laws and has not received any written communication from a governmental entity that alleges that the Company is not in compliance with or is in default or violation of any applicable law or regulation, except where such non-compliance, default or violation would not, individually or in the aggregate, reasonably be expected to have a Company Material Adverse Effect.

(n) The Company has not entered into any side letter or similar agreement or understanding (written or oral) with any Other Subscriber relating to or modifying such Other Subscriber’s Other Subscription Agreements. The Other Subscription Agreements reflect (i) the same Per Share Price and (ii) other terms with respect to the purchase of the Subscribed Shares and Pre-Funded Warrants that are no more favorable to such subscriber than the terms of this Subscription Agreement, other than terms particular to the regulatory requirements of such subscriber or its affiliates or related funds.

The Company has taken no action that is designed to terminate the registration of the Cayman Class A Shares under the Exchange Act other than in connection with the Domestication and subsequent registration under the Exchange Act of the Common Stock. Upon the consummation of the Transactions, the issued and outstanding Common Stock will be registered pursuant to Section 12(b) of the Exchange Act and listed for trading on Nasdaq, subject only to official notice thereof.

(q) The Company acknowledges that there have been no, and in issuing the Subscribed Shares and Pre-Funded Warrants the Company is not relying on any, representations, warranties, covenants and agreements made to the Company by Subscriber, any of its officers, directors, trustees, investment adviser or representatives or any other person or entity, expressly or by implication, other than those representations, warranties, covenants and agreements expressly stated in this Subscription Agreement.

(r) There has been no action taken by the Company, or, to the knowledge of the Company, any officer, director, equityholder, manager, employee, agent or representative of the Company, in each case, acting on behalf of the Company, in violation of any applicable Anti-Corruption Laws (as herein defined).

Subscriber acknowledges that certain information provided to the Subscriber by the Company on behalf of OHBP was based on estimates prepared by OHBP’s management, and such estimates were prepared based on assumptions that are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the estimates. Subscriber further acknowledges that certain financial information (whether historical, audited, unaudited or otherwise, or in the form of management estimates) was prepared without the participation of the Placement Agents and that the Placement Agents do not assume responsibility for independent verification of, or the accuracy or completeness of, such information or management estimates. Subscriber further acknowledges that no disclosure or offering document has been prepared or reviewed by the Placement Agents or any of their respective affiliates in connection with the offer and sale of the Subscribed Shares or the Pre-Funded Warrants or Pre-Funded Warrant Shares (upon exercise of Pre-Funded Warrants), and the Placement Agents and their respective affiliates and any control persons, officers, directors, employees, partners, agents or representatives of the Placement Agents and their respective affiliates have made no independent investigation with respect to the Company, OHBP, the Subscribed Shares or the Pre-Funded Warrants or Pre-Funded Warrant Shares (upon exercise of Pre-Funded Warrants), the Subscription or the Transactions or the accuracy, completeness or adequacy of any information supplied to the Placement Agents by the Company or OHBP.

Subscriber acknowledges and agrees that none of (i) any Other Subscriber pursuant to an Other Subscription Agreement, or any other investor pursuant to any agreement related to the private placement of the Subscribed Shares or Pre-Funded

Warrants (including such person’s affiliates or any control persons, officers, directors, employees, partners, agents or representatives of any of the foregoing), (ii) the Placement Agents, their affiliates or any control persons, officers, directors, employees, partners, agents or representatives of any of the foregoing (collectively, “Placement Agent Parties”), or (iii) any other party to the Business Combination Agreement or any Non-Party Affiliate (as defined below), shall have any liability to the Subscriber, or to any Other Subscriber or other investor, pursuant to, arising out of or relating to this Subscription Agreement, any Other Subscription Agreement, or any other agreement related to the private placement of the Subscribed Shares or Pre-Funded Warrants, the negotiation hereof or thereof or its subject matter, or the transactions contemplated hereby or thereby, including, without limitation, with respect to any action heretofore or hereafter taken or omitted to be taken by any of them in connection with the purchase of the Subscribed Shares, the purchase of the Pre-Funded Warrants or the receipt of Pre-Funded Warrant Shares upon exercise of the Pre-Funded Warrants or with respect to any claim (whether in tort, contract, under federal or state securities laws or otherwise) for breach of this Subscription Agreement, any Other Subscription Agreement, or any other agreement, or in respect of any written or oral representations made or alleged to be made in connection herewith, as expressly provided herein, or for any actual or alleged inaccuracies, misstatements or omissions with respect to any information or materials of any kind furnished by the Company, OHBP, or the Placement Agents concerning the Company, OHBP, the Placement Agents or any Non-Party Affiliate, any of their respective controlled affiliates, this Subscription Agreement or the transactions contemplated hereby.

Subscriber further acknowledges that Subscriber has not relied upon the Placement Agents in connection with Subscriber’s due diligence review of the offering of the Subscribed Shares or the Pre-Funded Warrants or Pre-Funded Warrant Shares (upon exercise of Pre-Funded Warrants) and of the Company and OHBP. In making its decision to purchase the Subscribed Shares or the Pre-Funded Warrants or Pre-Funded Warrant Shares (upon exercise of Pre-Funded Warrants), Subscriber has relied solely upon independent investigation made by Subscriber.

Subscriber acknowledges that the Company represents and warrants that the Subscribed Shares or the Pre-Funded Warrants or Pre-Funded Warrant Shares (upon exercise of Pre-Funded Warrants) (i) were not offered by any form of general advertising or, to the Subscriber’s knowledge, general solicitation, including methods described in section 502(c) of Regulation D and (ii) are not being offered in a manner involving a public offering under, or in a distribution in violation of, the Securities Act, or any state securities laws.

(i) Subscriber acknowledges that it is aware that there are substantial risks incident to the purchase and ownership of the Subscribed Shares or the Pre-Funded Warrants or Pre-Funded Warrant Shares (upon exercise of Pre-Funded Warrants), including those set forth in the SEC Reports. Subscriber has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of an investment in the Subscribed Shares or the Pre-Funded Warrants or Pre-Funded Warrant Shares (upon exercise of Pre-Funded Warrants), and Subscriber has had an opportunity to seek, and has sought, such accounting, legal, business and tax advice as Subscriber has considered necessary to make an informed investment decision.

Subscriber will not look to the Placement Agents for all or part of any such loss or losses that Subscriber may suffer, is able to sustain a complete loss on its investment in the Subscribed Shares or the Pre-Funded Warrants or Pre-Funded Warrant Shares (upon exercise of Pre-Funded Warrants), has no need for liquidity with respect to its investment in the Subscribed Shares or the Pre-Funded Warrants or Pre-Funded Warrant Shares (upon exercise of Pre-Funded Warrants)and has no reason to anticipate any change in circumstances, financial or otherwise, which may cause or require any sale or distribution of all or any part of the Subscribed Shares or the Pre-Funded Warrants or Pre-Funded Warrant Shares (upon exercise of Pre-Funded Warrants).

(k) Subscriber acknowledges that Subscriber shall be responsible for any of Subscriber’s tax liabilities that may arise as a result of the transactions contemplated by this Subscription Agreement, and that none of the Company, the Placement Agents, OHBP, or any of their respective agents or affiliates has offered Subscriber any tax advice relating to Subscriber’s investment in the Subscribed Shares or the Pre-Funded Warrants or Pre-Funded Warrant Shares (upon exercise of Pre-Funded Warrants), or made any representations, warranties or guarantees, whether written or oral, regarding the tax consequences of Subscriber’s investment in the Subscribed Shares or the Pre-Funded Warrants or Pre-Funded Warrant Shares (upon exercise of Pre-Funded Warrants).

Subscriber is not a non-U.S. shell bank or providing banking services to a non-U.S. shell bank. Subscriber represents that if it is a financial institution subject to the Bank Secrecy Act (31 U.S.C. Section 5311 et seq.), as amended by the USA PATRIOT Act of 2001 and its implementing regulations (collectively, the “BSA/PATRIOT Act”), that Subscriber maintains policies and procedures reasonably designed to comply with applicable obligations under the BSA/PATRIOT Act.

Notwithstanding the foregoing, in the case of a Subscriber that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of Subscriber’s assets and the portfolio managers have no direct knowledge of the investment decisions made by the portfolio managers managing other portions of Subscriber’s assets, the representation set forth in the first sentence of this subsection shall only apply with respect to the portion of the assets managed by the portfolio manager that made the investment decision to purchase the Subscribed Shares or the Pre-Funded Warrants or Pre-Funded Warrant Shares (upon exercise of Pre-Funded Warrants).

Part 800.244) will acquire a substantial interest in the Company as a result of the purchase and sale of Subscribed Shares or the Pre-Funded Warrants or Pre-Funded Warrant Shares (upon exercise of Pre-Funded Warrants)by Subscriber 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, in each case as a result of the purchase by Subscriber of Subscribed Shares or the Pre-Funded Warrants or Pre-Funded Warrant Shares (upon exercise of Pre-Funded Warrants) hereunder.

(s) No broker or finder has acted on behalf of Subscriber in connection with the sale of the Subscribed Shares or the Pre-Funded Warrants or Pre-Funded Warrant Shares (upon exercise of Pre-Funded Warrants) pursuant to this Subscription Agreement in such way as to create any liability on the Company.

(t) Subscriber acknowledges and agrees that the certificate or book entry position representing the Subscribed Shares, and any instrument representing the Pre-Funded Warrants or book entry position representing the Pre-Funded Warrant Shares (upon exercise of any Pre-Funded Warrants), will bear or reflect, as applicable, a legend substantially similar to the following:

“THIS SECURITY WAS ORIGINALLY ISSUED IN A TRANSACTION EXEMPT FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND THIS SECURITY MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM. THIS SECURITY MAY BE OFFERED, RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (I) PURSUANT TO ANY EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT, (II) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, OR (III) TO THE COMPANY, IN EACH OF CASES (I) THROUGH (III) IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES. THE COMPANY MAY REQUIRE THE DELIVERY OF A WRITTEN OPINION OF COUNSEL, CERTIFICATIONS AND/OR ANY OTHER INFORMATION IT REASONABLY REQUIRES TO CONFIRM THE SECURITIES ACT EXEMPTION FOR SUCH TRANSACTION.”

5. Registration Rights.

(a) The Company shall submit or file with the Commission (at the Company’s sole cost and expense) a registration statement registering the resale of the Subscribed Shares, the Pre-Funded Warrants and the Pre-Funded Warrant Shares (collectively, the “Registrable Securities”) and naming the Subscriber as a selling stockholder thereunder (the “Registration Statement”) no later than thirty (30) calendar days after the Closing (such deadline the “Filing Deadline”), and the Company shall use its commercially reasonable efforts to have the Registration Statement declared effective as soon as practicable after the filing thereof, but no later than the earlier of (i) the 60th calendar day (or 90th calendar day if the Commission notifies the Company that it will “review” the Registration Statement) following the earlier of (A) the filing of the Registration Statement and (B) the Filing Deadline, and (ii) the 7th Business Day after the date the Company is notified (orally or in writing, whichever is earlier) by the Commission that the Registration Statement will not be “reviewed” or will not be subject to further review (such deadline the “Effectiveness Deadline”), provided, that if the Filing Deadline or Effectiveness Deadline falls on Saturday, Sunday or other day that the Commission is closed for business, the Filing Deadline or Effectiveness Deadline, as the case may be, shall be extended to the next business day on which the Commission is open for business, provided, further, however, that the Company’s obligations to include Subscriber’s Registrable Securities in the Registration Statement are contingent upon Subscriber furnishing in a completed questionnaire in customary form to the Company that contains the information required by Commission rules for a Registration Statement regarding Subscriber, the securities of the Company held by Subscriber and the intended method of disposition of the Registrable Securities (which shall be limited to non-underwritten public offerings) (collectively, the “Subscriber Information”) as shall be reasonably requested by the Company to effect the registration of the Registrable Securities, and shall execute such documents in connection with such registration as the Company may reasonably request that are customary of a selling stockholder in similar situations, provided that Subscriber shall not in connection with the foregoing be required to execute any lock-up or similar agreement or otherwise be subject to any contractual restriction on the ability to transfer the Registrable Securities. Any failure by the Company to file the Registration Statement by the Filing Deadline or to cause the effectiveness of such Registration Statement by the Effectiveness Deadline shall not otherwise relieve the Company of its obligations to file or cause the effectiveness of the Registration Statement as set forth above in this Section 5. Upon notification by the Commission that any Registration Statement has been declared effective by the Commission, and within two (2) Business Days thereafter, the Company shall file the final prospectus under Rule 424 of the Securities Act.

(b) The Company will provide a copy of such portions of the draft of the Registration Statement that include Subscriber Information to Subscriber for review and comment at least two (2) Business Days in advance of filing the Registration Statement, provided, that, for the avoidance of doubt, in no event shall the Company be required to delay or postpone the filing of such Registration Statement as a result of or in connection with Subscriber’s review. With respect to the Subscriber Information, the Company shall request such information at least five (5) Business Days prior to the anticipated initial filing date of the Registration Statement.

(c) In no event shall the Subscriber be identified as a statutory underwriter in the Registration Statement unless requested by the Commission; provided, that if the Commission requests that the Subscriber be identified as a statutory underwriter in the Registration Statement, the Subscriber will have an opportunity to withdraw from the Registration Statement, it being understood that such withdrawal shall not relieve the Company of its obligation to register for resale the Registrable Securities held by the Subscriber at a later date.

(d) The Company agrees that, except for such times as the Company is permitted hereunder to suspend the use of the prospectus forming part of a Registration Statement, the Company will use its commercially reasonable efforts to, at its expense, cause such Registration Statement to remain effective with respect to Subscriber, keep any qualification, exemption or compliance under state securities laws which the Company determines to obtain continuously effective with respect to Subscriber, and to keep the applicable Registration Statement or any subsequent shelf registration statement free of any material misstatements or omissions, until the earlier of (i) three years from the issuance of the Subscribed Shares and Pre-Funded Warrants, as applicable, (ii) the date on which all of the Registrable Securities shall have been sold, or (iii) the first date on which the undersigned can sell all of its Registrable Securities (or shares received in exchange therefor) under Rule 144 without limitation as to the manner of sale, the amount of such securities that may be sold and without the requirement for the Company to be in compliance with the current public information required under Rule 144; provided, that the Company shall be entitled to delay or postpone the effectiveness of the Registration Statement, and from time to time to require Subscriber not to sell under the Registration Statement or to suspend the effectiveness thereof, if the negotiation or consummation of a transaction by the Company or its subsidiaries is pending or an event has occurred, which negotiation, consummation or event, the Company’s board of directors reasonably believes, upon the advice of outside legal counsel, would require additional disclosure by the Company in the Registration Statement of material non-public information that the Company has a bona fide business purpose for keeping confidential and the non-disclosure of which in the Registration Statement would be expected, in the reasonable determination of the Company’s board of directors, upon the advice of legal counsel, to cause the Registration Statement to fail to comply with applicable disclosure requirements (such circumstance, a “Suspension Event”); *provided, however, *that the Company may not delay or suspend the Registration Statement on more than two (2) occasions or for more than sixty (60) consecutive calendar days during any twelve-month period. Upon receipt of any written notice from the Company (which notice shall not contain any material non-public information regarding the Company and which notice shall not be subject to any duty of confidentiality) (A) of the occurrence of any Suspension Event during the period that the Registration Statement is effective or (B) that, as a result of a Suspension Event, the Registration Statement or related prospectus contains any untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made (in the case of the prospectus) not misleading, Subscriber agrees that it will promptly discontinue offers and sales of the Registrable Securities under the Registration Statement (excluding, for the avoidance of doubt, sales conducted pursuant to Rule 144 or any other applicable exemption to the registration requirements under the Securities Act) until Subscriber receives copies of a supplemental or amended prospectus (which the Company agrees to promptly prepare) that corrects the misstatement(s) or omission(s) referred to above and receives notice that any post-effective amendment has become effective or unless otherwise notified by the Company that it may resume such offers and sales (which notice shall not contain any material non-public information regarding the Company and which notice shall not be subject to any duty of confidentiality). If so directed by the Company, Subscriber will deliver to the Company or, in Subscriber’s sole discretion destroy, all copies of the prospectus covering the Registrable Securities in Subscriber’s possession; provided, however, that this obligation to deliver or destroy all copies of the prospectus covering the Registrable Securities shall not apply (i) to the extent Subscriber is required to retain a copy of such prospectus (a) in order to comply with applicable legal, regulatory, self-regulatory or professional requirements or (b) in accordance with a bona

fide pre-existing document retention policy or (ii) to copies stored electronically on archival servers as a result of automatic data back-up. Notwithstanding anything to the contrary herein, the Company shall use its commercially reasonable efforts to cause its transfer agent to deliver unlegended shares of Common Stock to a transferee of the Subscriber in connection with any sale of Registrable Securities with respect to which the Subscriber has entered into a contract for sale, prior to the Subscriber’s receipt of the notice of a Suspension Event and for which the Subscriber has not yet settled.

(e) If the Commission prevents the Company from including any or all of the securities proposed to be registered under the Registration Statement due to limitations on the use of Rule 415 of the Securities Act for the resale of the Registrable Securities by Subscriber, any other shares of Common Stock by any Other Subscribers or shares of Common Stock by any other selling stockholder named in the Registration Statement, the Company will promptly notify Subscriber of such event, and such Registration Statement shall register for resale such number of shares of Common Stock which is equal to the maximum number of Registrable Securities as is permitted by the Commission. In such event, the number of shares of Common Stock to be registered for Subscriber, such Other Subscriber or other selling stockholder named in the Registration Statement shall be reduced pro rata among all such selling stockholders (or as otherwise directed by the Commission) and as promptly as practicable after being permitted to register additional Registrable Securities under Rule 415 under the Securities Act, the Company shall use commercially reasonable efforts to amend the Registration Statement or file with the Commission and cause to be declared effective, as promptly as allowed by the Commission, one or more registration statements to register the resale of those Registrable Securities (as defined below) that were not registered on the initial Registration Statement, as so amended and to cause such amendment or Registration Statement to become effective as promptly as practicable. Any such amended or new registration statement(s) shall be deemed to be a “Registration Statement” and all provisions of Section 5 shall apply with respect thereto.

(f) In the case of a registration effected by the Company pursuant to this Subscription Agreement, the Company shall, upon reasonable request, inform Subscriber as to the status of such registration. The Company shall advise Subscriber as promptly as practicable, but in no event later than five (5) Business Days following or such earlier date as indicated:

(i) when a Registration Statement or any amendment thereto has been filed with the Commission and when such Registration Statement or any post-effective amendment thereto has become effective;

(ii) of any request by the Commission for amendments or supplements to any Registration Statement or the prospectus included therein or for additional information with respect to the Subscriber;

(iii) of the issuance by the Commission of any stop order suspending the effectiveness of any Registration Statement or the initiation of any proceedings for such purpose within two (2) Business Days of the Company’s notice of such event;

(iv) within two (2) Business Days of the receipt by the Company of any notification with respect to the suspension of the qualification of the Registrable Securities included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and

(v) subject to the provisions in this Subscription Agreement, of the occurrence of any event that requires the making of any changes in any Registration Statement or prospectus so that, as of such date, the statements therein are not misleading and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in the light of the circumstances under which they were made) not misleading.

Notwithstanding anything to the contrary set forth herein, the Company shall not, when so advising Subscriber of such events, provide Subscriber with any material, non-public information regarding the Company other than to the extent that providing notice to Subscriber of the occurrence of the events listed in clauses (i) through (v) above may constitute material, non-public information regarding the Company.

(g) The Company shall use its commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of any Registration Statement as soon as reasonably practicable.

(h) Except for such times as the Company is permitted hereunder to suspend, and has suspended, the use of a prospectus forming part of a Registration Statement as contemplated by this Subscription Agreement, the Company shall use its commercially reasonable efforts to as soon as reasonably practicable prepare a post-effective amendment to such Registration Statement or a supplement to the related prospectus, or file any other required document so that, as thereafter delivered to purchasers of the Registrable Securities included therein, such prospectus will not include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(i) The Company shall use its commercially reasonable efforts to cause all Subscribed Shares and Pre-Funded Warrant Shares to be listed on each securities exchange or market, if any, on which the Common Stock has been listed.

(j) The Company shall use its commercially reasonable efforts to take all other steps necessary to effect the registration of the Subscribed Shares, Pre-Funded Warrants and Pre-Funded Warrant Shares required hereby and to provide all customary and reasonable cooperation necessary to enable Subscriber to resell the Registrable Securities pursuant to the Registration Statement.

(k) In connection with any request by Subscriber for the removal of any restrictive legend from any Registrable Securities, Subscriber shall deliver to the Company (or its transfer agent, as applicable) such customary certifications, broker representation letters and other documents as the Company or its transfer agent may reasonably request to confirm the availability of an applicable exemption from the registration requirements of the Securities Act, including, without limitation, a written certification as to the applicable exemption (including, if applicable, compliance with the holding period, volume and manner-of-sale requirements of Rule 144) and, if the transfer is being effected through a broker-dealer, a customary broker representation letter.

(l) For purposes of this Section 5, “Subscribed Shares” shall be deemed to include, as of any date of determination, the Subscribed Shares and any equity security issued or issuable with respect to such Subscribed Shares by way of share split, dividend, distribution, recapitalization, merger, exchange, replacement or similar event; “Pre-Funded Warrants” shall be deemed to include, as of any date of determination, the Pre-Funded Warrant Shares and any equity security issued or issuable with respect to such Pre-Funded Warrant Shares by way of share split, dividend, distribution, recapitalization, merger, exchange, replacement or similar event; “Subscriber” shall mean the Subscriber or any affiliate of the Subscriber or other person to whom the rights under this Section 5 shall have been assigned, and “Registrable Securities” shall mean (i) all shares of Common Stock that are not then subject to forfeiture to the Company, (ii) all shares of Common Stock issuable upon exercise, conversion or exchange of any option, warrant or convertible security not then subject to vesting or forfeiture to the Company (including, for the avoidance of doubt, the Pre-Funded Warrants), (iii) all Pre-Funded Warrants, and (iv) all shares of Common Stock directly or indirectly issued or then issuable with respect to the securities referred to in clauses (i), (ii) or (iii) above by way of a stock dividend or stock split, or in connection with a combination of shares, recapitalization, merger, consolidation or other reorganization. As to any particular Registrable Securities, such securities shall cease to be Registrable Securities when (x) a Registration Statement with respect to the sale of such securities shall have become effective under the Securities Act and such securities shall have been disposed of in accordance with such Registration Statement, (y) such securities shall have been transferred pursuant to Rule 144 or (z) such securities shall have ceased to be outstanding.

6. 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 (in each case, except for those provisions expressly contemplated to survive such termination), upon the earliest to occur of (a) such date and time as the Business Combination Agreement is terminated in accordance with its terms; (b) the mutual written agreement of the parties hereto to terminate this Subscription Agreement; (c) if, on the Closing Date of the Transactions, any of the conditions to Closing set forth in Section 2 of this Subscription Agreement have not been satisfied as of the time required hereunder to be so satisfied or waived by the party entitled to grant such waiver and, as a result thereof, the transactions contemplated by this Subscription Agreement will not be or are not consummated at the Closing; or (d) if the Closing has not occurred by the Termination Date (as so defined in the Business Combination Agreement as of the date hereof, the “Outside Closing Date”); provided, that nothing herein will relieve any party from liability for any willful breach hereto 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 of this Subscription Agreement in accordance with this Section 6, any monies paid by Subscriber to the Company in connection herewith shall be promptly (and in any event within two (2) Business Days after such termination) returned to Subscriber.

7. Trust Account Waiver. Subscriber hereby acknowledges that, as described in the Company’s prospectus relating to its initial public offering dated May 19, 2026, the Company has established a trust account (the “Trust Account”) containing the proceeds of its initial public offering (the “IPO”) and from certain private placements occurring simultaneously with the IPO (including interest accrued from time to time thereon) for the benefit of the Company’s public shareholders and certain other parties (including the underwriters of the IPO). For and in consideration of the Company entering into this Subscription Agreement, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Subscriber 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 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”), and (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; provided, however, that nothing in this Section 7 shall (x) be deemed to limit any Subscriber’s right, title, interest or claim to the Trust Account, or any monies held therein, by virtue of such Subscriber’s (i) record or beneficial ownership of Cayman Class A Shares acquired by means other than pursuant to this Subscription Agreement or (ii) redemption rights in connection with the Transactions with respect to any Cayman Class A Shares owned by such Subscriber or limit Subscriber’s right to distributions from the Trust Account in accordance with the Company Constitutional Documents in respect of the Cayman Class A Shares acquired by any means other than pursuant to this Subscription Agreement, (y) serve to limit or prohibit Subscriber’s right to pursue a claim against the Company for legal relief against assets held outside the Trust Account, for specific performance or other equitable relief or (z) serve to limit or prohibit any claims that Subscriber may have in the future against the Company’s assets or funds that are not held in the Trust Account.

8. Indemnity.

(a) To the extent Subscriber is named as a selling stockholder under any Registration Statement, the Company shall indemnify and hold harmless, to the extent permitted by law, Subscriber, its directors, trustees, officers, partners, members, managers, stockholders, affiliates, employees, advisers and agents, and each person who controls Subscriber (within the meaning of the Securities Act or the Exchange Act) and each affiliate of Subscriber (within the meaning of Rule 405 under the Securities Act) from and against any and all losses, charges, claims, damages, liabilities, costs and expenses (including, without limitation, any reasonable and documented attorneys’ fees and expenses incurred in connection with defending or investigating any such action or claim) that arise out of or are caused by, based upon, arising out of or relating to (i) any untrue or alleged untrue statement of material fact contained in such Registration Statement, any prospectus included in such Registration Statement or preliminary prospectus or any amendment thereof or supplement thereto, or document incorporated therein by reference, (ii) any omission or alleged omission of a material fact required to be stated therein or necessary to make the

statements therein (in the case of a prospectus, in light of the circumstances in which they were made) not misleading, or (iii) any violation or alleged violation by the Company of the Securities Act, Exchange Act, or any state securities laws or rule or regulation thereunder, in connection with the performance of its obligations under Section 5 of this Subscription Agreement, except insofar as such untrue statement, alleged untrue statement, omissions, or alleged omission is caused by or contained in any information furnished in writing to the Company by or on behalf of Subscriber expressly for use therein.

(b) To the extent permitted by law, and in connection with any Registration Statement in which Subscriber is participating as a selling stockholder, Subscriber agrees, severally and not jointly with any Other Subscriber in the offering contemplated by this Subscription Agreement, to indemnify and hold harmless the Company and its directors, officers, employees and agents, and each person who controls the Company (within the meaning of the Securities Act or the Exchange Act) and each affiliate of the Company against any losses, charges, claims, damages, liabilities, costs and expenses (including, without limitation, reasonable attorneys’ fees and expenses incurred in connection with defending or investigating any such action or claim) caused by any untrue or alleged untrue statement of material fact contained in any Registration Statement, any prospectus included in any Registration Statement or preliminary prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in the light of the circumstances in which they were made) not misleading, but only to the extent that such untrue statement, alleged untrue statement, omissions, or alleged omission is caused by or contained in any Subscriber Information furnished in writing to the Company by or on behalf of Subscriber expressly for use therein; provided, however, that the indemnification contained in this Section 8 shall not apply to amounts paid in settlement of any such losses, charges, claims, damages, liabilities, costs and expenses if such settlement is effected without the consent of Subscriber. In no event shall the liability of Subscriber payable by way of indemnity or contribution under this Section 8(b) or under Section 8(e) be greater than the dollar amount of the net proceeds received by Subscriber upon the sale of the Subscribed Shares, Pre-Funded Warrants (or Pre-Funded Warrant Shares issuable upon exercise of the Pre-Funded Warrants), as applicable, purchased pursuant to this Subscription Agreement giving rise to such indemnification or contribution obligation.

(c) Any person entitled to indemnification herein shall (1) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided, that the failure to give prompt notice shall not impair any person’s right to indemnification hereunder to the extent such failure has not materially prejudiced the indemnifying party) and (2) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent shall not be unreasonably withheld, conditioned or delayed). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel (plus local counsel) for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of legal counsel to any indemnified party a conflict of interest exists between such indemnified party and any other of such indemnified parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement includes a statement or admission of fault and culpability on the part of such indemnified party or which settlement does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

(d) The indemnification provided for under this Subscription Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director, trustee, employee, agent, affiliate or controlling person of such indemnified party and shall survive the transfer of the Subscribed Shares, Pre-Funded Warrants (or Pre-Funded Warrant Shares issuable upon exercise of the Pre-Funded Warrants), as applicable, purchased pursuant to this Subscription Agreement. The indemnified parties are express third party beneficiaries of this Section 8, entitled to enforce their rights under this Section 8 as if party hereto.

(e) If the indemnification provided under this Section 8 from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, charges, claims, damages, liabilities, costs and expenses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result of such losses, charges, claims, damages, liabilities, costs and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by (or not made by, in the case of an omission), or relates to information supplied by or on behalf of (or not supplied by, in the case of an omission), such indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action. The amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include, subject to the limitations set forth above, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this Section 8 from any person who was not guilty of such fraudulent misrepresentation. Any contribution by Subscriber pursuant to this Section 8(e) (together with any indemnity under Section 8(b)) shall be no greater than the amount of net proceeds received by such Subscriber from the sale of such Subscribed Shares, Pre-Funded Warrants (or Pre-Funded Warrant Shares issuable upon exercise of the Pre-Funded Warrants), as applicable, purchased pursuant to this Subscription Agreement giving rise to this obligation. Notwithstanding anything to the contrary herein, in no event will any party be liable for consequential, special, exemplary or punitive damages in connection with this Subscription Agreement or the transactions contemplated hereby.

9. Company**’**s Covenants.

(c) While the Registration Statement is effective, the Company shall cause its counsel, or counsel acceptable to the transfer agent, to issue to the transfer agent a “blanket” legal opinion to allow the legend on the Registrable Securities to be removed upon a bona fide sale of such Subscribed Shares, Pre-Funded Warrants (or Pre-Funded Warrant Shares issuable upon exercise of the Pre-Funded Warrants), as applicable, pursuant to the plan of distribution set forth within any prospectus and pursuant to such effective Registration Statement in accordance with this Section 9. Upon request, the Company shall provide the Subscriber with contact information for the person responsible for the Company’s account at the transfer agent to facilitate transfers made pursuant to this Section 9. The Company shall be responsible for the fees of its transfer agent and its legal counsel (including for purposes of giving the opinion referenced herein) associated with such issuance and the Subscriber shall be responsible for its own fees or costs associated therewith (including its legal fees or costs of its legal counsel).

(d) As of the Closing Date, the Company has reserved, and the Company shall continue to reserve and keep available at all times, free of preemptive rights, a sufficient number of shares of Common Stock for the purpose of enabling the Company to issue the Pre-Funded Warrant Shares that are issuable upon the exercise of the Pre-Funded Warrants, if any.

On behalf of Subscriber and its affiliates, Subscriber releases the Placement Agents in respect of any losses, charges, claims, damages, liabilities, costs and expenses related to the Transactions and the purchase and sale of Subscribed Shares and Pre-Funded Warrants, as applicable, hereunder. On behalf of Subscriber and its affiliates, Subscriber agrees not to commence any litigation or bring any claim against any of the Placement Agents in any court or other forum which relates to, may arise out of, or is in connection with, the Transactions and the purchase and sale of the Subscribed Shares and Pre-Funded Warrants, as applicable, hereunder. This undertaking is given freely and after obtaining independent legal advice.

(f) Subscriber hereby agrees that it shall not, nor shall any person acting at Subscriber’s direction or pursuant to any understanding with Subscriber, directly or indirectly offer, sell, pledge, contract to sell, sell any option, engage in hedging activities or execute any “short sales” (as such term is defined in Regulation SHO under the Exchange Act, 17 CFR 242.200) or engage in other hedging transactions of any kind (other than pledges in the ordinary course of business as part of prime brokerage arrangements) directly with respect to the Subscribed Shares, the Pre-Funded Warrants or the Pre-Funded Warrant Shares during the period from the date of this Subscription Agreement through the Closing or the earlier termination of this Subscription Agreement. Notwithstanding anything to the contrary set forth herein, (i) nothing in this Section 10(f) shall prohibit any entities under common management with Subscriber that have no knowledge of this Subscription Agreement or of Subscriber’s participation in the Subscription or that share an investment adviser with Subscriber from entering into any short sales or engaging in other hedging transactions; (ii) in the case of a Subscriber that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Subscriber’s assets and the portfolio managers have no knowledge of the investment decisions made by the portfolio managers managing other portions of Subscriber’s assets, this Section 10(f) shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the Subscribed Shares (or the Pre-Funded Warrants, as applicable) covered by this Subscription Agreement; (iii) nothing herein shall prohibit any sale (including the exercise of any redemption right) of securities of the Company (1) held by Subscriber, its affiliates or any person or entity acting on behalf of Subscriber or any of its affiliates prior to the execution of this Subscription Agreement or (2) purchased by Subscriber, its affiliates or any person or entity acting on behalf of Subscriber or any of its affiliates after the execution of the Subscription Agreement; or (iv) nothing herein shall prohibit ordinary course hedging transactions so long as the sales or borrowings relating to such hedging transactions are not settled with the Subscribed Shares or Pre-Funded Warrant Shares subscribed for or issuable hereunder and the number of securities sold in such transactions does not exceed the number of securities owned or subscribed for at the time of such transactions. The Company acknowledges and agrees that, notwithstanding anything herein to the contrary, the Subscribed Shares and Pre-Funded Warrants may be pledged by Subscriber in connection with a bona fide margin agreement, provided that such pledge shall be (i) pursuant to an available exemption from the registration requirements of the Securities Act or (ii) pursuant to, and in accordance with, a registration statement that is effective under the Securities Act at the time of such pledge, and Subscriber effecting a pledge of the Subscribed Shares or Pre-Funded Warrants shall not be required to provide the Company with any notice thereof; provided, however, that neither the Company nor its counsel shall be required to take any action (or refrain from taking any action) in connection with any such pledge, other than providing any such lender of such margin agreement with an acknowledgment that the Subscribed Shares and Pre-Funded Warrants are not subject to any contractual lock up or prohibition on pledging, the form of such acknowledgment to be subject to review and comment by the Company in all respects.

(g) Neither this Subscription Agreement nor any rights that may accrue to Subscriber hereunder (other than the Subscribed Shares or Pre-Funded Warrants, as applicable, acquired hereunder, if any, and the registration rights set forth in Section 5 in connection with the transfer of any Subscribed Shares, Pre-Funded Warrants or Pre-Funded Warrant Shares (issuable upon exercise of the Pre-Funded Warrants)) may be transferred or assigned, subject to the provisions of the last sentence of this paragraph. Neither this Subscription Agreement nor any rights that may accrue to the Company hereunder may be transferred or assigned (provided, that, for the avoidance of doubt, the Company may transfer the Subscription Agreement and its rights hereunder solely in connection with the consummation of the Transactions and exclusively to another entity under the control of, or under common control with, the Company). Notwithstanding the foregoing, Subscriber may assign 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/adviser who acts on behalf of Subscriber) or, with the Company’s prior written consent, to another person; provided, that such affiliate or other person executes a joinder to this Subscription Agreement, such joinder to be in form and substance reasonably satisfactory to the Company, and no such assignment shall relieve Subscriber of its obligations hereunder if any such assignee fails to perform such obligations unless otherwise expressly agreed in writing by the Company.

(h) All the representations and warranties made by each party hereto in this Subscription Agreement shall survive the Closing. All of the covenants and agreements made by each party hereunder shall survive the Closing until the applicable statute of limitations or in accordance with their respective terms. For the avoidance of doubt, if for any reason the Closing does not occur prior to the consummation of the Transactions, all representations, warranties, covenants and agreements of the parties hereunder shall survive the consummation of the Transactions and remain in full force and effect.

(i) 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 Pre-Funded Warrants and to register the Subscribed Shares, Pre-Funded Warrants and Pre-Funded Warrant Shares for resale, and Subscriber shall promptly provide such information as may be reasonably requested to the extent reasonably available and to the extent consistent with Subscriber’s internal policies and procedures, provided that the Company agrees to keep such information confidential. Subscriber acknowledges that the Company may file a copy of the form of this Subscription Agreement with the Commission as an exhibit to a periodic report of the Company or a registration statement of the Company.

(j) This Subscription Agreement may not be amended, modified, supplemented or waived except by an instrument in writing, signed by the party against whom enforcement of such amendment, modification, supplement or waiver is sought. Additionally, no provision of this Subscription Agreement that would adversely affect, limit or impair any of the rights, protections or benefits afforded to the Placement Agents hereunder may be amended, modified, supplemented or waived, in each case without the prior written consent of each Placement Agent (which consent may be withheld in each Placement Agent’s sole discretion).

(k) 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.

(l) Except as otherwise provided herein, this Subscription Agreement shall be binding upon, and inure to 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. This Subscription Agreement shall not confer any rights or remedies upon any person other than the parties hereto and their respective successors and assigns, except that (i) the Placement Agents shall be third-party beneficiaries of the representations, warranties, acknowledgments, covenants, opinions, understandings and undertakings made by the Company, OHBP and their respective counsel and the representations and warranties made by the Subscriber in this Subscription Agreement, with full rights to enforce such provisions directly against the Company, OHBP and Subscriber to the fullest extent permitted by applicable law, and (ii) as set forth in Section 4, Section 5, Section 8, Section 10(b), Section 10(c), Section 10(e), Section 10(j), Section 10(m), Section 10(w) and this Section 10(l) with respect to the persons specifically referenced therein. The Company agrees not to take any position or make any claim that is contrary to or inconsistent with the rights, protections and benefits afforded to the Placement Agents under this Subscription Agreement.

(m) The parties hereto acknowledge and agree that (i) this Subscription Agreement is being entered into in order to induce the Company to execute and deliver the Business Combination Agreement and (ii) immediate and irreparable harm or 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 seek equitable relief, including in the form of an injunction or injunctions to prevent breaches or threatened breaches or restraining any violation or threatened violation of this Subscription Agreement and to enforce specifically the terms and provisions of this Subscription Agreement in the Designated Courts pursuant to Section 10(s), 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 seek 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. Additionally, the Placement Agents shall be entitled to seek equitable relief, including in the form of an injunction or injunctions to prevent breaches or threatened breaches or restraining any violation or threatened violation of this Subscription Agreement and to specifically enforce the Company’s, OHBP’s and Subscriber’s obligations under this Subscription Agreement for which the Placement Agents are third party beneficiaries, including the non-reliance and exculpation provisions in Section 4. 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 to the extent legally permissible; (y) not to assert that a remedy of specific enforcement pursuant to this Section 10(m) 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.

(n) 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.

(o) 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.

(p) This Subscription Agreement may be executed and delivered in one or more counterparts (including by facsimile or electronic mail or in .pdf) 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.

(q) This Subscription Agreement, and any claim or cause of action hereunder based upon, arising out of or related to this Subscription Agreement (whether based on law, in equity, in contract, in tort or any other theory) or the negotiation, execution, performance or enforcement of 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.

(r) EACH PARTY AND ANY PERSON ASSERTING RIGHTS AS A THIRD PARTY BENEFICIARY 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.

(s) 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 (or, to the extent such court does not have subject matter jurisdiction, the Superior Court of the State of Delaware), or, if it has or can acquire jurisdiction, in the United States District Court for the District 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. 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 10(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.

(t) 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 and then only with respect to the specific obligations set forth herein with respect to such party.

(u) If any change in the Common Stock shall occur between the date hereof and immediately prior to the Closing by reason of any reclassification, recapitalization, sub-division (including consolidation) or combination, exchange or readjustment of shares, or any share dividend, the number of Subscribed Shares issued to Subscriber (or Pre-Funded Warrants and Pre-Funded Warrant Shares, as the case may be) and the Per Share Price shall be appropriately adjusted to reflect such change.

(v) The Company shall, by 9:00 a.m., New York City time, on the first (1st) Business Day immediately following the date of this Subscription Agreement, issue one or more press releases or furnish or file with the Commission a Current Report on Form 8-K (collectively, the “Disclosure Document”) disclosing all material terms of this Subscription Agreement, the Other Subscription Agreements, the Business Combination Agreement, the transactions contemplated hereby and thereby, the Transactions and any other material, non-public information that the Company or OHBP has provided to Subscriber at any time prior to the filing of the Disclosure Document. Upon the issuance or filing of the Disclosure Document, to the Company’s knowledge, Subscriber and its affiliates (provided, that each of Subscriber and its affiliates is not, or is not an affiliate of any person who is, an existing investor in OHBP) shall not be in possession of any material, non-public information received from the Company or OHBP or any of their respective officers, directors, employees or agents, and Subscriber shall no longer be subject to any confidentiality or similar obligations under any current agreement, whether written or oral with the Company, OHBP, the Placement Agents, or any of their respective affiliates in connection with the Transactions. Except with the express written consent of Subscriber and unless prior thereto Subscriber shall have

executed a written agreement regarding the confidentiality and use of such information, the Company shall not, and shall cause its officers, directors, employees and agents, not to, provide Subscriber with any material, non-public information regarding the Company, OHBP or the Transactions from and after the filing of the Disclosure Document. The Company understands and confirms that the Subscriber and its affiliates will rely on the foregoing representations in effecting transactions in the securities of the Company. Notwithstanding anything in this Subscription Agreement to the contrary, the Company shall not and shall cause the Placement Agents and OHBP to not (i) 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, if applicable, in any press release, without the prior written consent of Subscriber and (ii) 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 law, regulatory agency or under the regulations of Nasdaq and (B) as expressly contemplated by Section 5(a) of this Subscription Agreement, in each of which case, the Company shall provide Subscriber with prior written notice of such disclosure, and shall reasonably consult with Subscriber regarding such disclosure. Subscriber will promptly provide any information reasonably requested by the Company or any of its affiliates that is required for any regulatory application or filing made or approval sought in connection with the Transactions (including filings with the Commission).

(w) The obligations of Subscriber under this Subscription Agreement are several and not joint with the obligations of any Other Subscriber under the Other Subscription Agreements, and Subscriber shall not be responsible in any way for the performance of the obligations of any Other Subscriber under this Subscription Agreement or any Other Subscriber under the Other Subscription Agreements. The decision of Subscriber to purchase Subscribed Shares and Pre-Funded Warrants, as applicable, pursuant to this Subscription Agreement has been made by Subscriber independently of any Other Subscriber and independently of any information, materials, statements or opinions as to the business, affairs, operations, assets, properties, liabilities, results of operations, condition (financial or otherwise) or prospects of the Company, OHBP or any of their respective subsidiaries which may have been made or given by any Other Subscriber or investor or by any agent or employee of any Other Subscriber or investor, and neither Subscriber nor any of its agents or employees shall have any liability to any Other Subscriber or investor (or any other person) relating to or arising from any such information, materials, statements or opinions. Nothing contained herein or in any Other Subscription Agreement, and no action taken by Subscriber or investor pursuant hereto or thereto, shall be deemed to constitute Subscriber and Other Subscribers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that Subscriber and Other Subscribers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by this Subscription Agreement and the Other Subscription Agreements. Subscriber acknowledges that no Other Subscriber has acted as agent for Subscriber in connection with making its investment hereunder and no Other Subscriber will be acting as agent of Subscriber in connection with monitoring its investment in the Subscribed Shares and Pre-Funded Warrants, as applicable, or enforcing its rights under this Subscription Agreement. Subscriber shall be entitled to independently protect and enforce its rights, including without limitation the rights arising out of this Subscription Agreement, and it shall not be necessary for any Other Subscriber or investor to be joined as an additional party in any proceeding for such purpose. The Company and the Subscriber each acknowledge and agree that nothing contained herein or in any Other Subscription Agreement, and no action taken by any Placement Agent in connection with the offering of the Subscribed Shares and Pre-Funded Warrants pursuant to this Subscription Agreement or any Other Subscription Agreement, shall be deemed to constitute any Placement Agent and any other Placement Agent as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that any Placement Agent and any other Placement Agent are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by this Subscription Agreement and the Other Subscription Agreements. The Company and the Subscriber each also acknowledge and agree that none of the Placement Agents or any other advisors involved in the Transactions shall have any authority to act for, or assume any obligation or responsibility on behalf of, one another or any party to this Subscription Agreement in connection with this Subscription Agreement, the Other Subscription Agreements, or the transactions contemplated hereby or thereby. Nothing contained herein or in any other agreement or document relating to the offering of the Subscribed Shares or Pre-Funded Warrants shall create a partnership, joint venture, association, syndicate or other similar relationship between any of the Placement Agents or between any of the Placement Agents and the Subscriber for any purpose whatsoever.

Warrant No. [•]		Original Issue Date: [•], 2026

Oak Hill Bio, Inc.,** a corporation duly organized under the laws of the State of Delaware (having domesticated from a Cayman Islands exempted company to a Delaware corporation in accordance with Section 388 of the General Corporation Law of the State of Delaware and Part XII of the Cayman Companies Act (Revised) immediately prior to the Original Issue Date) (the “Company”), hereby certifies that, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, [•] or its registered assigns (the “Holder”), is entitled, subject to the terms set forth below, to purchase from the Company up to a total of [•] shares of common stock, $0.0001 par value per share (the “Common Stock”), of the Company (each such share, a “Warrant Share” and all such shares, the “Warrant Shares”) at an exercise price per share equal to $0.0001 (the “Exercise Price”), in each case as adjusted from time to time as provided in Section* 9*, upon surrender of this Pre-Funded Warrant to Purchase Common Stock (including any Warrants to Purchase Common Stock issued in exchange, transfer or replacement hereof, the “Warrant”) at any time and from time to time on or after the date hereof (the “Original Issue Date”), subject to the following terms and conditions:

This Warrant is one of a series of similar warrants issued pursuant to that certain Subscription Agreement, dated [•], 2026, by and between the Company and the Subscriber identified therein (the “Purchase Agreement”), and is being issued as Exhibit A thereto. Capitalized terms used but not defined herein have the meanings given to them in the Purchase Agreement.

1. Definitions. For purposes of this Warrant, the following terms shall have the following meanings:

“Affiliate” means, with respect to any Person, any other Person that, directly or indirectly through one or more intermediates, controls, is controlled by or is under common control with such Person.

“Attribution Parties” means, collectively, the following Persons and entities: (i) any direct or indirect Affiliates of the Holder, (ii) any investment vehicle, including, any funds, feeder funds or managed accounts, currently, or from time to time after the date hereof, directly or indirectly managed or advised by the Holder’s investment manager, (iii) any Person acting or who could be deemed to be acting as a Group together with the Holder or any Attribution Parties and (iv) any other Persons whose beneficial ownership of the Company’s Common Stock would or could be aggregated with the Holder’s and/or any other Attribution Parties for purposes of Section 13(d) or Section 16 of the Exchange Act; provided, that, for the avoidance of doubt, the term “Attribution Parties” shall not include any other client, fund or account managed by the Holder’s investment manager that is not under common control with the Holder and that has independent investment discretion. For clarity, the purpose of the foregoing is to subject collectively the Holder and all other Attribution Parties to the Maximum Percentage.

“Closing Sale Price” means, for any security as of any date, the last trade price for such security on the Principal Trading Market for such security, as reported by Bloomberg Financial Markets, or, if such Principal Trading Market begins to operate on an extended hours basis and does not designate the last trade price, then the last trade price of such security prior to 4:00 P.M., New York City time, as reported by Bloomberg Financial Markets, or if the foregoing do not apply, the last trade price of such security in the over-the-counter market on the electronic bulletin board for such security as reported by Bloomberg Financial Markets. If the Closing Sale Price cannot be calculated for a security on a particular date on any of the foregoing bases, the Closing Sale Price of such security on such date shall be the fair market value as mutually determined by the Company and the Holder. If the Company and the Holder are unable to agree upon the fair market value of such security, then the Board of Directors of the Company shall use its good faith judgment to determine the fair market value. The Board of Directors’ determination shall be binding upon all parties absent demonstrable error. All such determinations shall be appropriately adjusted for any stock dividend, stock split, stock combination or other similar transaction during the applicable calculation period.

“Commission” means the U.S. Securities and Exchange Commission.

“Exchange Act” means the U.S. Securities Exchange Act of 1934, as amended, and all of the rules and regulations promulgated thereunder.

“Group” shall have the meaning ascribed to it in Section 13(d) of the Exchange Act, and all related rules, regulations and jurisprudence.

“Person” means an individual, partnership, corporation, limited liability company, business trust, joint stock company, trust, incorporated or unincorporated association, joint venture, government (or an agency or subdivision thereof) or any other entity or organization.

“Principal Trading Market” means the national securities exchange or other trading market on which the Common Stock is primarily listed on and quoted for trading, which, as of the Original Issue Date, shall be the Nasdaq Stock Market LLC.

“Securities Act” means the U.S. Securities Act of 1933, as amended, and all of the rules and regulations promulgated thereunder.

“Standard Settlement Period” means the standard settlement period, expressed in a number of Trading Days, for the Principal Trading Market with respect to the Common Stock that is in effect on the date of delivery of an applicable Exercise Notice, which as of the Original Issue Date was “T+1.”

“Trading Day” means any weekday on which the Principal Trading Market is normally open for trading.

“Transfer Agent” means Continental Stock Transfer & Trust Company, the Company’s transfer agent and registrar for the Common Stock, and any successor appointed in such capacity.

2. Issuance of Securities; Registration of Warrants. The Company shall register ownership of this Warrant, upon records to be maintained by the Company for that purpose (the “Warrant Register”), in the name of the record Holder (which shall include the initial Holder or, as the case may be, any assignee to which this Warrant is permissibly assigned hereunder) from time to time. The Company may deem and treat the registered Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for all other purposes, absent actual notice to the contrary.

3. Registration of Transfers. This Warrant and all rights hereunder (including, without limitation, any registration rights) are transferable, in whole or in part, upon surrender of this Warrant at the principal office of the Company or its designated agent, together with a written assignment of this Warrant substantially in the form attached hereto duly executed by the Holder or its agent or attorney and funds sufficient to pay any transfer taxes payable upon the making of such transfer. Subject to compliance with all applicable securities laws, the Company shall, or will cause its Transfer Agent to, register the transfer of all or any portion of this Warrant in the Warrant Register, upon surrender of this Warrant, and payment for all applicable transfer taxes (if any). Upon any such registration or transfer, a new warrant to purchase Common Stock in substantially the form of this Warrant (any such new warrant, a “New Warrant”) evidencing the portion of this Warrant so transferred shall be issued to the transferee, and a New Warrant evidencing the remaining portion of this Warrant not so transferred, if any, shall be issued to the transferring Holder. The acceptance of the New Warrant by the transferee thereof shall be deemed the acceptance by such transferee of all of the rights and obligations in respect of the New Warrant that the Holder has in respect of this Warrant. The Company shall, or will cause its Transfer Agent to, prepare, issue and deliver at the Company’s own expense any New Warrant under this Section*** 3*. Until due presentment for registration of transfer, the Company may treat the registered Holder hereof as the owner and holder for all purposes, and the Company shall not be affected by any notice to the contrary.

4. Exercise of Warrants.* *

(a) All or any part of this Warrant shall be exercisable by the registered Holder in any manner permitted by this Warrant (including Section*** 11*) at any time and from time to time on or after the Original Issue Date, and such rights shall not expire until exercised in full.

(b) The Holder may exercise this Warrant by delivering to the Company (i) an exercise notice, in the form attached as Schedule 1 hereto (the “Exercise Notice”), completed and duly signed, and (ii) payment of the Exercise Price for the number of Warrant Shares as to which this Warrant is being exercised (which may take the form of a “cashless exercise” if so indicated in the Exercise Notice pursuant to Section*** 10* below), and the date on which the last of such items is delivered to the Company (as determined in accordance with the notice provisions hereof) is an “Exercise Date.” The Holder shall not be required to deliver the original Warrant in order to effect an exercise hereunder. Execution and delivery of the Exercise Notice shall have the same effect as cancellation of the original Warrant and issuance of a New Warrant evidencing the right to purchase the remaining number of Warrant Shares, if any.

(c) The Holder and any assignee, by acceptance of this Warrant, acknowledge and agree that, by reason of the provisions of this section, following the purchase of a portion of the Warrant Shares hereunder, the number of Warrant Shares available for purchase hereunder at any given time may be less than the amount stated on the face hereof.

5. Delivery of Warrant Shares.* *

(a) Upon exercise of this Warrant, the Company shall promptly (but in no event later than the number of Trading Days comprising the Standard Settlement Period following the Exercise Date), upon the request of the Holder, cause the Transfer Agent to credit such aggregate number of shares of Common Stock specified by the Holder in the Exercise Notice and to which the Holder is entitled pursuant to such exercise (the “Exercise Shares”) to the Holder’s or its designee’s balance account with The Depository Trust Company (“DTC”) through its Deposit Withdrawal At Custodian system, so long as either (A) there is an effective registration statement permitting the issuance of the Warrant Shares to or the resale of such Warrant Shares by the Holder or (B) the Exercise Shares are eligible for resale by the Holder without volume or manner-of-sale restrictions pursuant to Rule 144 promulgated under the Securities Act (assuming cashless exercise of this Warrant). If (A) and (B) above are not true, the Company shall cause the Transfer Agent to either (i) record the Exercise Shares in the name of the Holder or its designee on the book-entry ledger statements reflecting the Exercise Shares with an appropriate legend regarding restriction on transferability, which shall be issued and dispatched by overnight courier to the address as specified in the Exercise Notice, and on the Company’s share register or (ii) issue such Exercise Shares in the name of the Holder or its designee in restricted book-entry form in the Company’s share register. The Holder, or any Person so designated by the Holder to receive Warrant Shares, shall be deemed to have become the holder of record of such Warrant Shares as of the Exercise Date, irrespective of the date such Warrant Shares are credited to the Holder’s DTC account, the date of the book entry positions or the date of delivery of the book-entry ledger statements evidencing such Exercise Shares, as the case may be.

(b) In addition to any other rights available to the Holder, if the Company fails to cause the Transfer Agent to deliver to the Holder or its designee Exercise Shares in the manner required pursuant to Section*** 5(a)* within the Standard Settlement Period following the Exercise Date (other than a failure caused by incorrect or incomplete information provided by Holder to the Company) and the Holder or the Holder’s broker on its behalf purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder of the Warrant Shares which the Holder anticipated receiving upon such exercise (a “Buy-In”) but did not receive within the Standard Settlement Period, then the Company shall, within two Trading Days after the Holder’s request and in the Holder’s sole discretion, either (i) promptly honor its obligation to deliver to the Holder or its designee the Exercise Shares pursuant to Section*** 5(a)* and pay cash to the Holder in an amount equal to the excess (if any) of the Holder’s total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased in the Buy-In, less the product of (A) the number of shares of Common Stock purchased in the Buy-In, times (B) the Closing Sale Price of a share of Common Stock on the Exercise Date, or (ii) upon written notice to the Company, cancel such exercise in full and have the Company reinstate the portion of this Warrant for the number of Warrant Shares that were subject to such exercise, in which case such exercise shall be deemed not to have occurred. The Holder shall provide the Company written notice promptly after the occurrence of a Buy-In, indicating the amounts payable to the Holder in respect of the Buy-In together with applicable confirmations and other evidence reasonably requested by the Company.

(c) To the extent permitted by law and subject to Section*** 5(b), the Company’s obligations to issue and deliver Warrant Shares in accordance with and subject to the terms hereof (including the limitations set forth in Section** 11* below) are absolute and unconditional, irrespective of any action or inaction by the Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any Person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by the Holder or any other Person of any obligation to the Company or any violation or alleged violation of law by the Holder or any other Person, and irrespective of any other circumstance that might otherwise limit such obligation of the Company to the Holder in connection with the issuance of Warrant Shares. Subject to Section*** 5(b)*, nothing herein shall limit the Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver Exercise Shares; provided, however, that the Holder shall not be entitled to both (i) require the Company to reinstate the portion of the Warrant and equivalent number of Warrant Shares for which such exercise was not timely honored and (ii) receive the number of shares of Common Stock that would have been issued if the Company had timely complied with its delivery requirements under Section 5(a).

6. Charges, Taxes and Expenses. Issuance and delivery of Exercise Shares shall be made without charge to the Holder for any issue or transfer tax, transfer agent fee or other incidental tax or expense (excluding any applicable stamp duties) in respect of the issuance of such shares, all of which taxes and expenses shall be paid by the Company; provided, however, that the Company shall not be required to pay any tax that may be payable in respect of any transfer involved in the registration of any Warrant Shares or the Warrants in a name other than that of the Holder or an Affiliate thereof. The Holder shall be responsible for all other tax liability that may arise as a result of holding or transferring this Warrant or receiving Warrant Shares upon exercise hereof.

7. Replacement of Warrant. If this Warrant is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation hereof, or in lieu of and substitution for this Warrant, a New Warrant, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction (in such case) and, in each case, a customary and reasonable contractual indemnity, if requested by the Company. If a New Warrant is requested as a result of a mutilation of this Warrant, then the Holder shall deliver such mutilated Warrant to the Company as a condition precedent to the Company’s obligation to issue the New Warrant.

8. Reservation of Warrant Shares. The Company covenants that it will, at all times while this Warrant is outstanding, reserve and keep available out of the aggregate of its authorized but unissued and otherwise unreserved Common Stock, solely for the purpose of enabling it to issue Warrant Shares upon exercise of this Warrant as herein provided, 100% of the number of Warrant Shares that are initially issuable and deliverable upon the exercise of this entire Warrant, free from preemptive rights or any other contingent purchase rights of persons other than the Holder (taking into account the adjustments and restrictions of Section*** 9*). The Company covenants that all Warrant Shares so issuable and deliverable shall, upon issuance and the payment of the applicable Exercise Price in accordance with the terms hereof, be duly and validly authorized, issued and fully paid and non-assessable. The Company will take all such action as may be reasonably necessary to assure that such shares of Common Stock may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of any securities exchange or automated quotation system upon which the Common Stock may be listed. The Company further covenants that it will not, without the prior written consent of the Holder, take any actions to increase the par value of the Common Stock at any time while this Warrant is outstanding. If at any time while this Warrant is outstanding, the Company does not have a sufficient number of authorized and unreserved shares of Common Stock to satisfy its obligations under this Warrant, the Company shall promptly take all action necessary to increase the Company’s authorized shares of Common Stock to an amount sufficient to allow the Company to reserve 100% of the Warrant Shares then issuable upon exercise of this Warrant.

9. Certain Adjustments. The Exercise Price and number of Warrant Shares issuable upon exercise of this Warrant (the “Number of Warrant Shares”) are subject to adjustment from time to time as set forth in this Section*** 9*.**

(a) Stock Dividends and Splits. If the Company, at any time while this Warrant is outstanding, (i) pays a stock dividend on its Common Stock or otherwise makes a distribution on any class of capital stock issued and outstanding on the Original Issue Date and in accordance with the terms of such stock on the Original Issue Date or as amended, that is payable in shares of Common Stock, (ii) subdivides its outstanding shares of Common Stock into a larger number of shares of Common Stock, (iii) combines its outstanding shares of Common Stock into a smaller number of shares of Common Stock or (iv) issues by reclassification of shares of capital stock any additional shares of Common Stock of the Company, then in each such case the Number of Warrant Shares shall be multiplied by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately after such event and the denominator of which shall be the number of shares of Common Stock outstanding immediately before such event. Any adjustment made pursuant to clause (i) of this paragraph shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution, provided, however, that if such record date shall have been fixed and such dividend is not fully paid on the date fixed therefor, the Number of Warrant Shares shall be recomputed accordingly as of the close

of business on such record date and thereafter the Number of Warrant Shares shall be adjusted pursuant to this paragraph as of the time of actual payment of such dividends. Any adjustment pursuant to clause (ii), (iii) or (iv) of this paragraph shall become effective immediately after the effective date of such subdivision, combination or issuance.

(b) Pro Rata Distributions. If, on or after the Original Issue Date, the Company shall declare or make any dividend or other pro rata distribution of its assets (or rights to acquire its assets) to holders of shares of Common Stock, by way of return of capital or otherwise (including, without limitation, any distribution of cash, stock or other securities, property, options, evidence of indebtedness or any other assets by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction, but, for the avoidance of doubt, excluding any distribution of shares of Common Stock subject to Section 9(a), any distribution of Purchase Rights (as defined below) subject to Section*** 9(c)* and any Fundamental Transaction (as defined below) subject to Section*** 9(d))* (a “Distribution”) then, in each such case, the Holder shall be entitled to participate in such Distribution to the same extent that the Holder would have participated therein if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant (without regard to any limitations or restrictions on exercise of this Warrant, including without limitation, the Maximum Percentage (as defined below)) immediately before the date on which a record is taken for such Distribution, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the participation in such Distribution; provided, that to the extent that the Holder’s right to participate in any such Distribution would result in the Holder and the other Attribution Parties exceeding the Maximum Percentage, then the Holder shall not be entitled to participate in such Distribution to such extent (and shall not be entitled to beneficial ownership of such shares of Common Stock as a result of such Distribution to such extent) and the portion of such Distribution shall be held in abeyance for the benefit of the Holder until such time or times as its right thereto would not result in the Holder and the other Attribution Parties exceeding the Maximum Percentage, at which time or times the Holder shall be granted such Distribution (and any Distributions declared or made on such initial Distribution or on any subsequent Distribution held similarly in abeyance) to the same extent as if there had been no such limitation.

(c) Purchase Rights. If at any time on or after the Original Issue Date, the Company grants, issues or sells any Options, Convertible Securities or rights to purchase stock, warrants, securities or other property, in each case pro rata to the record holders of any class of Common Stock (the “Purchase Rights”), then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant (without regard to any limitations or restrictions on exercise of this Warrant, including without limitation, the Maximum Percentage) immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of Common Stock are to be determined for the grant, issuance or sale of such Purchase Rights; provided, that to the extent that the Holder’s right to participate in any such Purchase Right would result in the Holder and the other Attribution Parties exceeding the Maximum Percentage, then the Holder shall not be entitled to participate in such Purchase Right to such extent (and shall not be entitled to beneficial ownership of such Common Stock as a result of such Purchase Right (and beneficial ownership) to such extent) and at the Holder’s election, in its sole discretion, either (1) such Purchase Right to such extent shall be held in abeyance for the benefit

of the Holder until such time or times as its right thereto would not result in the Holder and the other Attribution Parties exceeding the Maximum Percentage, at which time or times the Holder shall be granted such right (and any Purchase Right granted, issued or sold on such initial Purchase Right or on any subsequent Purchase Right to be held similarly in abeyance) to the same extent as if there had been no such limitation or (2) the Company shall offer the Holder the right upon exercise of such Purchase Right to acquire a security (e.g. a pre-funded warrant) that would not result in the Holder and the other Attribution Parties exceeding the Maximum Percentage but will otherwise to the extent possible have economic and other rights, preferences and privileges substantially consistent and on par with the securities or other property issuable upon exercise of the originally offered Purchase Rights). As used in this Section*** 9(c)*, (i) “Options” means any rights, warrants or options to subscribe for or purchase shares of Common Stock or Convertible Securities and (ii) “Convertible Securities” means any stock or securities (other than Options) directly or indirectly convertible into or exercisable or exchangeable for shares of Common Stock.

(d) Fundamental Transactions. If, at any time while this Warrant is outstanding (i) the Company effects any merger or consolidation of the Company with or into another Person, in which the Company is not the surviving entity or in which the stockholders of the Company immediately prior to such merger or consolidation do not own, directly or indirectly, at least 50% of the voting power of the surviving entity immediately after such merger or consolidation, (ii) the Company effects any sale to another Person of all or substantially all of its assets in one or a series of related transactions, (iii) pursuant to any tender offer or exchange offer (whether by the Company or another Person), holders of capital stock tender shares representing more than 50% of the voting power of the capital stock of the Company and the Company or such other Person, as applicable, accepts such tender for payment, (iv) the Company consummates a stock purchase agreement or other business combination (including, without limitation, a reorganization, recapitalization, spin-off or scheme of arrangement) with another Person whereby such other Person acquires more than 50% of the voting power of the capital stock of the Company (except for any such transaction in which the stockholders of the Company immediately prior to such transaction maintain, in substantially the same proportions, the voting power of such Person immediately after the transaction) or (v) the Company effects any reclassification of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property (other than as a result of a subdivision or combination of shares of Common Stock covered by Section*** 9(a)* above) (in any such case, a “Fundamental Transaction”) provided, however, that, for the avoidance of doubt, neither (A) the domestication of the Company from a Cayman Islands exempted company to a Delaware corporation in connection with the transactions contemplated by the Purchase Agreement (the “Domestication”) nor (B) the acquisition by the Company of OHB Pediatrics Ltd. pursuant to the business combination agreement entered into in connection with the Purchase Agreement, shall constitute a Fundamental Transaction for purposes of this** **Warrant; then following such Fundamental Transaction the Holder shall have the right to receive, upon exercise of this Warrant, the same amount and kind of securities, cash or property as it would have been entitled to receive upon the occurrence of such Fundamental Transaction if it had been, immediately prior to such Fundamental Transaction, the holder of the number of Warrant Shares then issuable upon exercise in full of this Warrant (including any Distributions or Purchase Rights then held in abeyance pursuant to Sections 9(b) or 9(c) above) without regard to any limitations on exercise contained herein (the “Alternate Consideration”). If holders of Common Stock are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder shall

be given the same choice as to the Alternate Consideration it receives upon any exercise of this Warrant following such Fundamental Transaction. The Company shall not effect any Fundamental Transaction in which the Company is not the surviving entity or the Alternate Consideration includes securities of another Person unless (i) the Alternate Consideration is solely cash and the Company provides for the simultaneous “cashless exercise” of this Warrant pursuant to Section*** 10* below or (ii) prior to or simultaneously with the consummation thereof, any successor to the Company, surviving entity or other Person (including any purchaser of assets of the Company) shall assume the obligation to deliver to the Holder such Alternate Consideration as, in accordance with the foregoing provisions, the Holder may be entitled to receive, and the other obligations under this Warrant. The provisions of this paragraph (d) shall similarly apply to subsequent transactions analogous to a Fundamental Transaction type.

(e) Number of Warrant Shares. Simultaneously with any adjustment to the Number of Warrant Shares pursuant to Section*** 9*, the Exercise Price shall be increased or decreased proportionately, so that after such adjustment the aggregate Exercise Price payable hereunder for the increased or decreased Number of Warrant Shares shall be the same as the aggregate Exercise Price in effect immediately prior to such adjustment. Notwithstanding the foregoing, in no event may the Exercise Price be adjusted below the par value of the Common Stock then in effect.

(f) Calculations. All calculations under this Section*** 9* shall be made to the nearest one-tenth of one cent or the nearest share, as applicable.

(g) Notice of Adjustments. Upon the occurrence of each adjustment pursuant to this Section*** 9*, the Company at its expense will, at the written request of the Holder, promptly (and in any event within five (5) Trading Days) compute such adjustment, in good faith, in accordance with the terms of this Warrant and prepare a certificate setting forth such adjustment, including a statement of the adjusted Exercise Price and adjusted number or type of Warrant Shares or other securities issuable upon exercise of this Warrant (as applicable), describing the transactions giving rise to such adjustments and showing in detail the facts upon which such adjustment is based. Upon written request, the Company will promptly deliver a copy of each such certificate to the Holder and to the Company’s transfer agent.

(h) Notice of Corporate Events. If, while this Warrant is outstanding, the Company (i) declares a dividend or any other distribution of cash, securities or other property in respect of its Common Stock, including, without limitation, any granting of rights or warrants to subscribe for or purchase any capital stock of the Company or any subsidiary, (ii) authorizes or approves, enters into any agreement contemplating or solicits stockholder approval for any Fundamental Transaction or (iii) authorizes the voluntary dissolution, liquidation or winding up of the affairs of the Company, then the Company shall deliver to the Holder a notice of such transaction at least ten days prior to the applicable record or effective date on which a Person would need to hold Common Stock in order to participate in or vote with respect to such transaction; provided, however, that the failure to deliver such notice or any defect therein shall not affect the validity of the corporate action required to be described in such notice. In addition, if while this Warrant is outstanding, the Company authorizes or approves, enters into any agreement contemplating or solicits stockholder approval for any Fundamental Transaction contemplated by Section*** 9(d), other than a Fundamental Transaction under clause (iii) of Section** 9(d),* the Company shall deliver to the Holder a notice of such Fundamental Transaction at least

30 days prior to the date such Fundamental Transaction is consummated. Holder agrees to maintain any information disclosed pursuant to this Section*** 9(h)* in confidence until such information is publicly available, and shall comply with applicable law with respect to trading in the Company’s securities following receipt of any such information.

10. Payment of Exercise Price. Notwithstanding anything contained herein to the contrary, the Holder may, in its sole discretion, satisfy its obligation to pay the Exercise Price through a “cashless exercise”, in which event the Company shall issue to the Holder the number of Warrant Shares in an exchange of securities effected pursuant to Section 3(a)(9) of the Securities Act, determined as follows:

X = Y [(A-B)/A] where:

“X” equals the number of Warrant Shares to be issued to the Holder;

“Y” equals the total number of Warrant Shares with respect to which this Warrant is then being exercised;

“A” equals the Closing Sale Price of the shares of Common Stock (as reported by Bloomberg Financial Market) as of the Trading Day immediately preceding the Exercise Date); and

“B” equals the Exercise Price then in effect for the applicable Warrant Shares at the time of such exercise.

For purposes of Rule 144 promulgated under the Securities Act, it is intended, understood and acknowledged that the Warrant Shares issued in a “cashless exercise” transaction shall be deemed to have been acquired by the Holder, and the holding period for the Warrant Shares shall be deemed to have commenced, on the Original Issue Date (provided* that the Commission continues to take the position that such treatment is proper at the time of such exercise). In the event that a registration statement registering the issuance of Warrant Shares is, for any reason, not effective at the time of exercise of this Warrant, then this Warrant may only be exercised through a cashless exercise, as set forth in this Section** 10*. If the Warrant Shares are issued in such a cashless exercise, the Company acknowledges and agrees that, in accordance with Section 3(a)(9) of the Securities Act, the Exercise Shares issued in such exercise shall take on the registered characteristics of the Warrants being exercised and may be tacked on to the holding period of the Warrants being exercised. Except as set forth in Section*** 5(b)* (Buy-in Remedy) and Section*** 12* (No Fractional Shares), in no event will the exercise of this Warrant be settled in cash.

11. Limitations on Exercise.* *

(a) Notwithstanding anything to the contrary contained herein, the Company shall not effect the exercise of any portion of this Warrant, and the Holder of this Warrant shall not have the right to exercise any portion of the Warrant, and any such exercise shall be null and void ab initio and treated as if the exercise had not been made, to the extent that immediately prior to or following such exercise, the Holder, together with the Attribution Parties, beneficially owns or would

beneficially own as determined in accordance with Section 13(d) of the Exchange Act and the rules promulgated thereunder, in excess of [4.99][9.99]% (the “Maximum Percentage”) of the Common Stock that would be issued and outstanding following such exercise. For purposes of calculating beneficial ownership for determining whether the Maximum Percentage is or will be exceeded, the aggregate number of shares of Common Stock held and/or beneficially owned by the Holder together with the Attribution Parties, shall include the number of shares of Common Stock held and/or beneficially owned by the Holder together with the Attribution Parties plus the number of shares of Common Stock issuable upon exercise of the relevant Warrant with respect to which the determination is being made but shall exclude the number of shares of Common Stock which would be issuable upon (i) exercise of the remaining, unexercised Warrant held and/or beneficially owned by the Holder or the Attribution Parties and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company held and/or beneficially owned by such Holder or any Attribution Party (including, without limitation, any convertible notes, convertible stock or warrants) that are subject to a limitation on conversion or exercise analogous to the limitation contained herein. For purposes of this Section*** 11(a), beneficial ownership of the Holder or the Attribution Parties shall, except as set forth in the immediately preceding sentence, be calculated and determined in accordance with Section 13(d) of the Exchange Act and the rules promulgated thereunder. For purposes of this Warrant, in determining the number of outstanding shares of Common Stock, a Holder of this Warrant may rely on the number of outstanding shares of Common Stock as reflected in (1) the Company’s most recent Form 10-K, Form 10-Q, Current Report on Form 8-K or other public filing with the Securities and Exchange Commission, as the case may be, (2) a more recent public announcement by the Company or (3) any other notice by the Company or the Company’s transfer agent setting forth the number of shares of Common Stock outstanding (such issued and outstanding shares, the “Reported Outstanding Share Number”). For any reason at any time, upon the written or oral request of the Holder, the Company shall within one business day confirm orally and in writing or by electronic mail to the Holder the number of shares of Common Stock then outstanding. The Holder shall disclose to the Company the number of shares of Common Stock that it, together with the Attribution Parties holds and/or beneficially owns and has the right to acquire through the exercise of derivative securities and any limitations on exercise or conversion analogous to the limitation contained herein contemporaneously or immediately prior to submitting an Exercise Notice for the relevant Warrant. If the Company receives an Exercise Notice from the Holder at a time when the actual number of outstanding shares of Common Stock is less than the Reported Outstanding Share Number, the Company shall (i) notify the Holder in writing of the number of shares of Common Stock then outstanding and, to the extent that such Exercise Notice would otherwise cause the Holder’s, together with the Attribution Parties’, beneficial ownership, as determined pursuant to this Section** 11(a)*, to exceed the Maximum Percentage, the Holder must notify the Company of a reduced number of Warrant Shares to be purchased pursuant to such Exercise Notice (the number of shares by which such purchase is reduced, the “Reduction Shares”) and (ii) as soon as reasonably practicable, the Company shall return to the Holder any exercise price paid by the Holder for the Reduction Shares. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Warrant, by the Holder and the Attribution Parties since the date as of which the Reported Outstanding Share Number was reported. In the event that the issuance of Common Stock to the Holder upon exercise of this Warrant results in the Holder, together with the Attribution Parties, being deemed to beneficially own, in the aggregate, more than the Maximum Percentage of the number of outstanding shares of Common Stock (as determined under Section 13(d) of the Exchange Act), the number of shares so issued by which the Holder’s, together with

the Attribution Parties’, aggregate beneficial ownership exceeds the Maximum Percentage (the “Excess Shares”) shall be deemed null and void and shall be cancelled ab initio, and the Holder and/or the Attribution Parties shall not have the power to vote or to transfer the Excess Shares. As soon as reasonably practicable after the issuance of the Excess Shares has been deemed null and void, the Company shall return to the Holder the exercise price paid by the Holder for the Excess Shares. By written notice to the Company, a Holder of this Warrant may from time to time increase or decrease the Maximum Percentage to any other percentage not in excess of 19.99% specified in such notice; provided* *that any increase in the Maximum Percentage will not be effective until the 61st day after such notice is delivered to the Company and shall not negatively affect any partial exercise effected prior to such change; and provided further that, for purposes of clarity, any decrease in the Maximum Percentage shall be effective immediately upon written notice to the Company.

(b) This Section*** 11* shall not restrict the number of shares of Common Stock which a Holder or the Attribution Parties may receive or beneficially own in order to determine the amount of securities or other consideration that such Holder or the Attribution Parties may receive in the event of a Fundamental Transaction as contemplated in Section*** 9(d)* of this Warrant. For purposes of clarity, the shares of Common Stock issuable pursuant to the terms of this Warrant in excess of the Maximum Percentage shall not be deemed to be beneficially owned by the Holder or the Attribution Parties for any purpose including for purposes of Section 13(d) of the Exchange Act and the rules promulgated thereunder or Section 16 of the Exchange Act and the rules promulgated thereunder, including Rule 16a-1(a)(1). No prior inability to exercise this Warrant pursuant to this paragraph shall have any effect on the applicability of the provisions of this paragraph with respect to any subsequent determination of exercisability. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section*** 11* to the extent necessary to correct this paragraph or any portion of this paragraph which may be defective or inconsistent with the intended beneficial ownership limitation contained in this Section*** 11* or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitation contained in this paragraph may not be waived and shall apply to a successor holder of this Warrant.

12. No Fractional Shares. No fractional Warrant Shares will be issued in connection with any exercise of this Warrant. In lieu of any fractional shares that would otherwise be issuable, the number of Warrant Shares to be issued shall be rounded down to the next whole number and the Company shall pay the Holder in cash the fair market value (based on the Closing Sale Price) for any such fractional shares.

13. Notices. Any and all notices or other communications or deliveries hereunder (including, without limitation, any Exercise Notice) shall be in writing and shall be deemed given and effective on the earliest of (i) the date of transmission, if such notice or communication is delivered confirmed e-mail at the e-mail address specified in the books and records of the Transfer Agent prior to 5:30 P.M., New York City time, on a Trading Day, (ii) the next Trading Day after the date of transmission, if such notice or communication is delivered via confirmed e-mail at the e-mail address specified in the books and records of the Transfer Agent on a day that is not a Trading Day or later than 5:30 P.M., New York City time, on any Trading Day, (iii) the Trading Day following the date of mailing, if sent by nationally recognized overnight courier service specifying next business day delivery, or (iv) upon actual receipt by the Person to whom such notice is required to be given, if by hand delivery.

14. Warrant Agent. The Company shall initially serve as warrant agent under this Warrant. Upon 30 days’ notice to the Holder, the Company may appoint a new warrant agent. Any corporation into which the Company or any new warrant agent may be merged or any corporation resulting from any consolidation to which the Company or any new warrant agent shall be a party or any corporation to which the Company or any new warrant agent transfers substantially all of its corporate trust or shareholders services business shall be a successor warrant agent under this Warrant without any further act. Any such successor warrant agent shall promptly cause notice of its succession as warrant agent to be mailed (by first class mail, postage prepaid) to the Holder at the Holder’s last address as shown on the Warrant Register.

15. Miscellaneous.

(a) No Rights as a Stockholder. Except as otherwise set forth in this Warrant, the Holder, solely in such Person’s capacity as a holder of this Warrant, shall not be entitled to vote or receive dividends or be deemed the holder of share capital of the Company for any purpose, nor shall anything contained in this Warrant be construed to confer upon the Holder, solely in such Person’s capacity as the Holder of this Warrant, any of the rights of a stockholder of the Company or any right to vote, give or withhold consent to any corporate action (whether any reorganization, issue of stock, reclassification of stock, consolidation, merger, amalgamation, conveyance or otherwise), receive notice of meetings, receive dividends or subscription rights, or otherwise, prior to the issuance to the Holder of the Warrant Shares which such Person is then entitled to receive upon the due exercise of this Warrant. In addition, nothing contained in this Warrant shall be construed as imposing any liabilities on the Holder to purchase any securities (upon exercise of this Warrant or otherwise) or as a stockholder of the Company, whether such liabilities are asserted by the Company or by creditors of the Company.

(b) Further Assurances. Except and to the extent as waived or consented to by the Holder, the Company shall not by any action, including, without limitation, amending its certificate or articles of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to protect the rights of Holder as set forth in this Warrant against impairment. Without limiting the generality of the foregoing, the Company will (a) not increase the par value of any Warrant Shares above the amount payable therefor upon such exercise immediately prior to such increase in par value, (b) take all such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and non-assessable Warrant Shares upon the exercise of this Warrant, and (c) use commercially reasonable efforts to obtain all such authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof as may be necessary to enable the Company to perform its obligations under this Warrant. Before taking any action which would result in an adjustment in the number of Warrant Shares for which this Warrant is exercisable or in the Exercise Price, the Company shall obtain all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any public regulatory body or bodies having jurisdiction thereof.

(c) Successors and Assigns. Subject to compliance with applicable securities laws, this Warrant may be assigned by the Holder. This Warrant may not be assigned by the Company without the written consent of the Holder, except to a successor in the event of a Fundamental Transaction. This Warrant shall be binding on and inure to the benefit of the Company and the Holder and their respective successors and assigns. Subject to the preceding sentence, nothing in this Warrant shall be construed to give to any Person other than the Company and the Holder any legal or equitable right, remedy or cause of action under this Warrant.

(d) Amendment and Waiver. This Warrant may be amended only in writing signed by the Company and the Holder, or their successors and assigns. Except as otherwise provided herein, the Company may take any action herein prohibited, or omit to perform any act herein required to be performed by it, only if the Company has obtained the written consent of the Holder.

(e) Acceptance. Receipt of this Warrant by the Holder shall constitute acceptance of and agreement to all of the terms and conditions contained herein.

(f) Governing Law; Jurisdiction. ALL QUESTIONS CONCERNING THE CONSTRUCTION, VALIDITY, ENFORCEMENT AND INTERPRETATION OF THIS WARRANT SHALL BE GOVERNED BY AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO THE PRINCIPLES OF CONFLICTS OF LAW THEREOF. EACH OF THE COMPANY AND THE HOLDER HEREBY IRREVOCABLY SUBMITS TO THE EXCLUSIVE JURISDICTION OF THE STATE AND FEDERAL COURTS SITTING IN THE CITY OF NEW YORK, BOROUGH OF MANHATTAN, FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION HEREWITH OR WITH ANY TRANSACTION CONTEMPLATED HEREBY OR DISCUSSED HEREIN (INCLUDING WITH RESPECT TO THE ENFORCEMENT OF ANY OF THE TRANSACTION DOCUMENTS), AND HEREBY IRREVOCABLY WAIVES, AND AGREES NOT TO ASSERT IN ANY SUIT, ACTION OR PROCEEDING, ANY CLAIM THAT IT IS NOT PERSONALLY SUBJECT TO THE JURISDICTION OF ANY SUCH COURT. EACH OF THE COMPANY AND THE HOLDER HEREBY IRREVOCABLY WAIVES PERSONAL SERVICE OF PROCESS AND CONSENTS TO PROCESS BEING SERVED IN ANY SUCH SUIT, ACTION OR PROCEEDING BY MAILING A COPY THEREOF VIA REGISTERED OR CERTIFIED MAIL OR OVERNIGHT DELIVERY (WITH EVIDENCE OF DELIVERY) TO SUCH PERSON AT THE ADDRESS IN EFFECT FOR NOTICES TO IT AND AGREES THAT SUCH SERVICE SHALL CONSTITUTE GOOD AND SUFFICIENT SERVICE OF PROCESS AND NOTICE THEREOF. NOTHING CONTAINED HEREIN SHALL BE DEEMED TO LIMIT IN ANY WAY ANY RIGHT TO SERVE PROCESS IN ANY MANNER PERMITTED BY LAW. EACH OF THE COMPANY AND THE HOLDER HEREBY WAIVES ALL RIGHTS TO A TRIAL BY JURY.

(g) Headings. The headings herein are for convenience only, do not constitute a part of this Warrant and shall not be deemed to limit or affect any of the provisions hereof.

(h) Severability. If any part or provision of this Warrant is held unenforceable or in conflict with the applicable laws or regulations of any jurisdiction, the invalid or unenforceable part or provisions shall be replaced with a provision which accomplishes, to the extent possible, the original business purpose of such part or provision in a valid and enforceable manner, and the remainder of this Warrant shall remain binding upon the parties hereto.
