Item 1.01

Entry into a Material Definitive Agreement

On July 26, 2026, Research Alliance Corporation III, a Cayman Islands exempted company ("RACC"), OHB Pediatrics Ltd., a company incorporated under the laws of England and Wales (the "Company"), and the shareholders of the Company (the "Shareholders"), entered into a Business Combination Agreement (as it may be amended, supplemented or otherwise modified from time to time, the "Business Combination Agreement"), pursuant to which, among other things and subject to the terms and conditions contained therein, RACC will acquire 100% of the outstanding shares in the capital of the Company from the Shareholders in exchange for newly issued shares of RACC common stock (the "Share Acquisition"). The transactions contemplated by the Business Combination Agreement are referred to herein as the "Transactions." The Business Combination Agreement and the Transactions were unanimously approved by the boards of directors of each of RACC and the Company. The Transactions are expected to close in the second half of 2026, following the receipt of the requisite approval of RACC's shareholders and the fulfillment of other customary closing conditions.

Business Combination Agreement

The Domestication

The Business Combination Agreement provides, among other things, that at least one business day prior to the closing of the transactions contemplated by the Business Combination Agreement (the "Closing" and the date upon which the Closing actually occurs, the "Closing Date"), (a) each outstanding Class B ordinary share of RACC will be converted, on a one-for-one basis, into a Class A ordinary share of RACC (the "Sponsor Share Conversion") and (b) RACC will de-register from the Register of Companies in the Cayman Islands and transfer by way of continuation from the Cayman Islands to Delaware and domesticate as a Delaware corporation in accordance with Section 388 of the General Corporation Law of the State of Delaware (the "DGCL") and Part 12 of the Companies Act (Revised) of the Cayman Islands (the "Domestication"). In connection with the Domestication, (i) each then outstanding Class A ordinary share of RACC (each, a "RACC Class A Share") will be converted automatically, on a one-for-one basis, into one share of common stock, par value $0.0001 per share, of RACC (the "RACC Common Stock") and (ii) RACC will file a certificate of incorporation (the "RACC COI") with the Secretary of State of the State of Delaware and adopt bylaws (the "RACC Bylaws").

RACC Shareholder Redemptions

RACC will provide the holders of RACC Class A Shares the right to have all or a portion of their RACC Class A Shares redeemed for cash in connection with the Transactions, in accordance with RACC's governing documents, for a per-share price equal to the pro rata portion of the funds then in RACC's trust account (including interest earned on the funds held in the trust account, less taxes paid or payable).

The Share Acquisition

Subject to the terms and conditions of the Business Combination Agreement, at the Closing and following the Domestication, each of the Shareholders will sell and transfer to RACC 100% of the outstanding shares in the capital of the Company (the "Company Shares") in exchange for newly issued shares of RACC Common Stock. The number of shares of RACC Common Stock to be issued as consideration for the Share Acquisition (the "Closing Consideration") is equal to (a) the Adjusted Equity Value (as defined below) divided by (b) $10.00. Each Shareholder will receive a number of shares of RACC Common Stock equal to the Exchange Ratio (as defined below) multiplied by the number of Company Shares held by such Shareholder. The "Adjusted Equity Value" means the sum of (a) a base equity value of $160,000,000 (the "Base Equity Value") plus (b) the Company SAFE Amount (as defined below). The "Exchange Ratio" means the Closing Consideration divided by the number of fully-diluted Company Shares outstanding as of immediately prior to the Closing. Upon consummation of the Share Acquisition, the Company will become a wholly-owned subsidiary of RACC.

Representations and Warranties; Covenants

The Business Combination Agreement contains representations, warranties and covenants of each of the parties thereto that are customary for transactions of this type, including with respect to the operations of RACC and the Company prior to the Closing and the preparation and filing of a registration statement on Form S-4 relating to the Transactions, which will include a prospectus and proxy statement of RACC (the "Registration Statement / Proxy Statement") with the Securities and Exchange Commission (the "SEC"). The parties have also undertaken to procure clearance under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended. In addition, the board of directors of RACC has agreed to adopt an equity incentive plan (the "RACC Equity Incentive Plan") and an employee stock purchase plan (the "RACC Employee Stock Purchase Plan") prior to the effectiveness of the Registration Statement / Proxy Statement, as described in the Business Combination Agreement.

Governance

RACC has agreed to take all action within its power as may be necessary or appropriate such that, effective immediately after the Closing, the board of directors of RACC will consist of the individuals set forth on a schedule to the Business Combination Agreement, which will be divided into three classes.

Conditions to Closing

The obligation of the parties to consummate the Transactions is subject to certain closing conditions, including, but not limited to, (i) the expiration or termination of the applicable waiting period under the HSR Act, (ii) no governmental order or law preventing or prohibiting the consummation of the Transactions being in effect, (iii) the effectiveness of the Registration Statement / Proxy Statement, (iv) receipt of the requisite approvals of RACC's shareholders, (v) the approval for listing of RACC Common Stock on The Nasdaq Capital Market ("Nasdaq"), (vi) the completion of the Pre-Closing Reorganization (as defined in the Business Combination Agreement), (vii) the constitution of the board of directors of RACC as contemplated by the Business Combination Agreement, and (viii) the execution and delivery of the Investor Rights Agreement (as defined below).

The obligation of RACC to consummate the Transactions is also subject to the fulfillment of other customary closing conditions, including, but not limited to, (i) there having been no Company Material Adverse Effect (as defined in the Business Combination Agreement) since the date of the Business Combination Agreement that is continuing, (ii) the receipt of certain required third party consents, and (iii) the delivery by each Shareholder of a duly executed stock transfer form in respect of all Company Shares held by such Shareholder.

The obligation of the Company and the Shareholders to consummate the Transactions is also subject to the fulfillment of other customary closing conditions, including, but not limited to, (i) there having been no RACC Material Adverse Effect (as defined in the Business Combination Agreement) since the date of the Business Combination Agreement that is continuing, (ii) the Backstop Agreement being in full force and effect and the Sponsor (or an affiliate thereof) having complied in all material respects with its obligations thereunder, and (iii) the consummation of the Domestication.

Termination

The Business Combination Agreement may be terminated under certain customary and limited circumstances prior to the Closing, including, but not limited to, (i) by mutual written consent of RACC, the Company and the Shareholders, (ii) by RACC if the representations and warranties of the Company or the Shareholders are not true and correct or if the Company or any Shareholder fails to perform any covenant or agreement set forth in the Business Combination Agreement such that certain conditions to Closing cannot be satisfied and the breach or breaches of such representations or warranties or the failure to perform such covenant or agreement, as applicable, are not cured or cannot be cured within certain specified time periods, (iii) by the Shareholders if the representations and warranties of RACC are not true and correct or if RACC fails to perform any covenant or agreement set forth in the Business Combination Agreement such that certain conditions to Closing cannot be satisfied and the breach or breaches of such representations or warranties or the failure to perform such covenant or agreement, as applicable, are not cured or cannot be cured within certain specified time periods, (iv) subject to certain limited exceptions, by either RACC or the Shareholders if the Transactions shall not have been consummated by a date that is six months from the date of the Business Combination Agreement (subject to automatic extension in certain circumstances), (v) by either RACC or the Shareholders if any governmental authority has issued a final and non-appealable order prohibiting the Transactions, and (vi) by either RACC or the Shareholders if the requisite RACC shareholder approvals are not obtained after the conclusion of the meeting at which RACC's shareholders voted on such matters.

If the Business Combination Agreement is validly terminated, none of the parties will have any liability or any further obligation under the Business Combination Agreement other than customary surviving provisions, except in the case of willful and material breach or fraud.

The foregoing description of the Business Combination Agreement and the Transactions does not purport to be complete and is qualified in its entirety by the terms and conditions of the Business Combination Agreement and any related agreements. The Business Combination Agreement contains representations, warranties and covenants that the respective parties made to each other as of the date of such agreement or other specific dates. The assertions embodied in those representations, warranties and covenants were made for purposes of the contract among the respective parties and are subject to important qualifications and limitations agreed to by the parties in connection with negotiating such agreement. The Business Combination Agreement is not intended to provide any other factual information about RACC, the Company, the Shareholders or any other party to the Business Combination Agreement or any related agreement. In particular, the representations, warranties, covenants and agreements contained in the Business Combination Agreement, which were made only for purposes of such agreement and as of specific dates, were solely for the benefit of the parties, are subject to limitations agreed upon by the parties (including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties instead of establishing these matters as facts) and are subject to standards of materiality applicable to the parties that may differ from those applicable to investors and security holders. Investors and security holders are not third-party beneficiaries under the Business Combination Agreement and should not rely on the representations, warranties, covenants and agreements, or any descriptions thereof, as characterizations of the actual state of facts or condition of any party to the Business Combination Agreement. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Business Combination Agreement, which subsequent information may or may not be fully reflected in RACC's public disclosures.

The foregoing description of the Business Combination Agreement is qualified in its entirety by reference to the Business Combination Agreement filed as Exhibit 2.1 to this Current Report on Form 8-K.

Related Agreements

The Business Combination Agreement contemplates the execution of various additional agreements and instruments, on or before the Closing, including, among others, the following:

Sponsor Letter Agreement

Concurrently with the execution of the Business Combination Agreement, RACC, Research Alliance Holdings III LLC, a Cayman Islands limited liability company (the "Sponsor"), Michael F. MacLean and Timothy J. Miller (the "Other Class B Shareholders") and the Company entered into the Sponsor Letter Agreement (the "Sponsor Letter Agreement"), pursuant to which the Sponsor and each Other Class B Shareholder, as holders of Class B ordinary shares, have agreed to, among other things, (i) vote in favor of the Business Combination Agreement and the Transactions, (ii) waive any adjustment to the conversion ratio set forth in the governing documents of RACC or any other anti-dilution or similar protection with respect to the Class B ordinary shares (whether resulting from the transactions contemplated by the Subscription Agreements (as defined below) or otherwise), (iii) be bound by certain other covenants and agreements related to the Transactions, (iv) be bound by certain transfer restrictions with respect to his or its shares in RACC prior to the Closing, and (v) be subject to the restrictions contemplated by the Lock-Up Agreements (as defined below) in each case, on the terms and subject to the conditions set forth in the Sponsor Letter Agreement.

Company SAFEs

Concurrently with the execution of the Business Combination Agreement, each of RA Capital Healthcare Fund, L.P. and RA Capital Nexus Fund IV, L.P. (the "SAFE Holders") entered into a simple agreement for future equity (collectively, the "Company SAFEs") with the Company, pursuant to which the SAFE Holders have agreed to provide interim financing to the Company in the aggregate principal amount of $45,000,000, bearing interest at a rate of 8% per annum. The Company SAFEs will convert into ordinary shares of the Company immediately prior to the Closing. The sum of the principal amount of the Company SAFEs and all accrued and unpaid interest thereon as of the Closing Date is referred to as the "Company SAFE Amount." The Company SAFE Amount is added to the Base Equity Value to determine the Adjusted Equity Value for purposes of calculating the Closing Consideration.

The foregoing description of the Company SAFEs is subject to and qualified in its entirety by reference to the full text of the form of Company SAFE, a copy of which is included as Exhibit 10.2 to this Current Report on Form 8-K.

The obligations of the PIPE Investors to consummate the PIPE Financing are further subject to additional conditions, including, among other things: (i) the Business Combination Agreement shall not have been amended, modified, or supplemented, and no condition waived thereunder, in a manner that would reasonably be expected to

materially and adversely affect the economic benefits that a PIPE Investor (in its capacity as such) would reasonably expect to receive under the Subscription Agreements; (ii) the material truth and accuracy of the representations and warranties of RACC in the Subscription Agreements, subject to customary bringdown standards; (iii) no subscription agreement, or other agreements or understandings (including side letters) entered into in connection with the sale of RACC Common Stock or Pre-Funded Warrants under the Subscription Agreements, with any other PIPE Investor shall have been amended, modified, or waived in any manner that benefits such other PIPE Investor unless all PIPE Investors have been offered substantially the same benefits (other than terms particular to the legal or regulatory requirements of such other PIPE Investor or its affiliates or related persons); (iv) all specified consents, waivers or other authorizations and notices, required to be made in connection with the issuance and sale of RACC Common Stock and the Pre-Funded Warrants, if any, under the Subscription Agreements shall have been obtained or made, except where failure to so obtain would not prevent RACC from consummating the transactions contemplated by the Subscription Agreements; (v) material compliance by RACC with its covenants, agreements and conditions under the Subscription Agreements; and (vi) there has not occurred any Material Adverse Effect (as defined in the Business Combination Agreement) since the date of the Subscription Agreements that is continuing.

Investor Rights Agreement

At the Closing, RACC, the Sponsor, RA Capital Healthcare Fund, L.P., RA Capital Nexus Fund IV, L.P., certain existing shareholders of RACC, and certain former shareholders of the Company will enter into an investor rights agreement (the "Investor Rights Agreement"). Pursuant to the Investor Rights Agreement, among other things, RACC will agree that, within 30 calendar days following the Closing Date, RACC will file with the SEC (at RACC's sole cost and expense) a registration statement on Form S-1 (or Form S-3, if then eligible) for a shelf registration covering the resale of all registrable securities held by or issuable to the parties thereto (the "Resale Registration Statement"), and RACC will use its commercially reasonable efforts to have the Resale Registration Statement declared effective as soon as reasonably practicable after the filing thereof. Such holders will be entitled to customary piggyback registration rights and demand registration rights, including underwritten demands.

The Investor Rights Agreement will amend and restate the registration and shareholder rights agreement that was entered into by RACC, the Sponsor and the Other Class B Shareholders in connection with RACC's initial public offering. The Investor Rights Agreement will terminate on the earlier of (a) the fifth anniversary of the date of the Investor Rights Agreement or (b) with respect to any holder party thereto, on the date that such holder no longer holds any registrable securities (as defined therein).

The foregoing description of the Investor Rights Agreement is subject to and qualified in its entirety by reference to the full text of the form of Investor Rights Agreement, a copy of which is attached as Exhibit 10.5 hereto, and the terms of which are incorporated herein by reference.

Lock-Up Agreement

At the Closing, the Sponsor, the Other Class B Shareholders, and certain existing shareholders of the Company will each enter into a lock-up agreement (the "Lock-Up Agreement") with RACC.

The foregoing description of the Lock-Up Agreement is subject to and qualified in its entirety by reference to the full text of the form of Lock-Up Agreement, a copy of which is included as Exhibit 10.6 to this Current Report on Form 8-K.

The foregoing descriptions of the RACC COI and RACC Bylaws do not purport to be complete and are qualified in their entirety by the terms and conditions of the forms of the RACC COI and RACC Bylaws, copies of which are included as Exhibit D and Exhibit E, respectively, to the Business Combination Agreement (attached as Exhibit 2.1 hereto), and the terms of which are incorporated herein by reference.

RACC Equity Incentive Plan and RACC Employee Stock Purchase Plan

Prior to the effectiveness of the Registration Statement / Proxy Statement, the board of directors of RACC will approve and adopt, in each case subject to approval by the RACC shareholders, the RACC Equity Incentive Plan and the RACC Employee Stock Purchase Plan. The RACC Equity Incentive Plan will provide for equity incentive compensation grants to certain employees and consultants (including non-employee directors) in the form of stock options, stock appreciation rights, restricted stock, restricted stock units, and/or other stock-based and cash-based awards. The RACC Employee Stock Purchase Plan will permit eligible employees to purchase RACC Common Stock at a discount under Section 423 of the Internal Revenue Code of 1986, as amended, or as otherwise agreed.

The initial number of shares of RACC Common Stock reserved and available for issuance under the RACC Equity Incentive Plan will equal 15% of RACC Common Stock outstanding as of the Closing. Additionally, the number of shares of RACC Common Stock reserved and available for issuance under the RACC Equity Incentive Plan will be automatically increased annually on the first day of each fiscal year beginning with the 2027 fiscal year in an amount equal to 5% of RACC Common Stock outstanding on the last day of the immediately preceding fiscal year, or such lesser amount as determined by the administrator of the RACC Equity Incentive Plan.

The initial number of shares of RACC Common Stock reserved and available for issuance under the RACC Employee Stock Purchase Plan will equal 2% of RACC Common Stock outstanding as of the Closing. Additionally, on the first day of each fiscal year beginning with the 2028 fiscal year, the number of shares of RACC Common Stock reserved and available for issuance under the RACC Employee Stock Purchase Plan will be increased annually in an amount equal to 2% of RACC Common Stock outstanding on the last day of the immediately preceding fiscal year, or such lesser number of shares as determined by the administrator of the RACC Employee Stock Purchase Plan.

The foregoing descriptions of the RACC Equity Incentive Plan and RACC Employee Stock Purchase Plan do not purport to be complete and will be qualified in their entirety by the terms and conditions of the RACC Equity Incentive Plan and RACC Employee Stock Purchase Plan when finalized.

Accordingly, undue reliance should not be placed upon the forward-looking statements. Neither RACC, the Company nor any of their respective affiliates undertake any obligation to update these forward-looking statements, except as required by law.

The Group Companies and the Company Products are, and since the incorporation of the Company have been, in compliance in all material respects with all Regulatory Permits, and to the knowledge of the Company, no event or circumstance has occurred which (with or without due notice or lapse of time or both) would reasonably be expected to result in the failure of a Group Company to be in compliance in all material respects with the terms of any such Regulatory Permit.

clinical or clinical trials of any Company Product sponsored or conducted or being sponsored or conducted by or on behalf of any Group Company, placing a "clinical hold" or requiring the termination, suspension, investigation or material adverse modification of such studies, tests or trials and, to the knowledge of Company, there are no pending actions by any Governmental Authority under any Healthcare Laws against or affecting any Group Company or with respect to any Company Product.

(f) Since the incorporation of the Company, the Group Companies have not distributed any Company Products that were upon their shipment by any Group Company adulterated or misbranded in violation of 21 U.S.C. § 331 or any other Governmental Authority's jurisdiction. No Company Products have been seized, withdrawn, recalled, detained or subject to a suspension (other than in the ordinary course of business) of research, manufacturing or distribution, and, to the knowledge of the Company, there are no facts or circumstances reasonably likely to cause (i) the seizure, denial, withdrawal, recall, or detention, or public health notification or safety alert relating to any Company Product or (ii) a termination or suspension of research, clinical investigation, manufacturing or distributing of any Company Product, in either case, except as would not have a Company Material Adverse Effect.

No Group Company is the subject of any pending or, to the knowledge of Company, threatened investigation by the FDA pursuant to its Fraud, Untrue Statements of Material Facts, Bribery, and Illegal Gratuities Final Policy or by any other Governmental Authority pursuant to equivalent laws.

4.12 Intellectual Property.

(a) Section 4.12(a)(i) of the Company Disclosure Schedules sets forth, as of the date hereof, a complete and accurate list and details of all registered and applied-for Intellectual Property owned or purported to be owned by a Group Company ("Company Registered IP"). Except as set forth on Section 4.12(a)(ii) of the Company Disclosure Schedules, the Group Companies exclusively own all Company Registered IP and all other Company Owned IP, free and clear of all Liens (other than Permitted Liens). All Company Registered IP is subsisting and, to the knowledge of the Company, all Company Registered IP (excluding applications for registration) are valid and enforceable. Except as set forth on Section 4.12(a)(iii) of the Company Disclosure Schedules, to the knowledge of the Company, no loss or expiration of any Company Registered IP or any other Company Owned IP is threatened or pending, except for any such Intellectual Property expiring at the end of its statutory term, and not as a result of any act or omission by any Group Company.

(b) The Group Companies either own, or have valid licenses or rights to use, all Intellectual Property required to carry on the Business as currently conducted and no Shareholder (including the Key Shareholder) or Affiliate of any Group Company owns, controls or otherwise possesses any Intellectual Property that is necessary for the Business as currently conducted; provided, that, the foregoing shall not be interpreted as a representation or warranty regarding the Infringement of Intellectual Property of a third party.

(c) The Company Owned IP, together with the Material Inbound Licenses, constitute all Intellectual Property necessary to operate the Business as currently conducted; provided, that, the foregoing shall not be interpreted as a representation and warranty regarding the Infringement of Intellectual Property of a third party. Each Group Company (i) has performed in all respects obligations imposed on it in the Company IP Licenses, (ii) has made all payments required to be paid by it under the applicable Company IP Licenses to date, and (iii) such Group Company is not in material breach or material default of any applicable Company IP License. None of the Group Companies has granted any exclusive license of Company Owned IP to any Person and the Company has not received written notice of any disputes under any Material Inbound License in the past two years. For the avoidance of doubt, the Material Inbound Licenses include the Roche License Agreement and all rights granted to the Company thereunder, and no Affiliate of any Group Company holds any concurrent or shared interest in the Roche License Agreement that would diminish or qualify the Group Companies' (or SPAC's after the Closing) rights thereunder.

34

(d) Except as set forth on Section 4.12(d) of the Company Disclosure Schedules, as at the date of this Agreement, no Action is pending or, to the Company's knowledge, threatened in writing against a Group Company, that challenges the validity, enforceability or ownership of, or the Group Companies' right to use, sell, exploit, license or sublicense, any Company Owned IP. During the past two years prior to the date of this Agreement, no Group Company has received any written, or to the knowledge of the Company, oral, notice or claim: (i) asserting that the Business activities of any Group Company have Infringed or are Infringing the Intellectual Property of any other Person; or (ii) claiming or demanding a right to be indemnified, defended, held harmless, or reimbursed by any Group Company with respect to any Infringement claim or Action. To the knowledge of the Company, no Company Product is currently Infringing, or has, in the past two years, Infringed any valid Intellectual Property of any other Person. There are no subsisting Orders to which any Group Company is a party that (A) restrict the rights of a Group Company to use, transfer, license or enforce any Company Owned IP in any material respect, (B) restrict the conduct of the Business of a Group Company in any material respect to accommodate a third party's Intellectual Property, or (C) grant any third party any ownership or exclusive rights with respect to any Company Owned IP. To the Company's knowledge, no third party is Infringing any Company Owned IP. During the past two years, no Group Company has notified any third party or otherwise alleged, in writing, that a third party is Infringing any Company Owned IP.

(e) All current and former founders, employees, consultants, independent contractors and services providers (including those engaged via a third party such as an employer of record) who created any material Intellectual Property in the course of their work or services for any Group Company (each, a "Contributor") have executed a valid written agreement that assigned to a Group Company the Contributor's right, title and interest in such Intellectual Property, and all such Intellectual Property constitutes Company Owned IP. To the knowledge of the Company, no Contributors have claimed any ownership interest in any Company Owned IP since the incorporation of the Company.

(f) Each Group Company has taken commercially reasonable steps designed to protect and maintain the secrecy and confidentiality of all material Trade Secrets included in the Company Owned IP or owned by any third party and for which a Group Company has a written confidentiality obligation. To the knowledge of the Company, such Trade Secrets have not been subject to unauthorized access by a third party.

(g) No funding, facilities or personnel of any Governmental Authority, university or research center were used, directly or indirectly, to develop, create or reduce to practice any Company Owned IP and no Governmental Authority, university, college or other educational institution, multi-national, bi-national or international organization, or research center has any ownership interest in or exclusive license to, or has the right to obtain any ownership interest in or exclusive license to (including no assignment, grant-back, license, march-in or other rights to), any Company Owned IP.

(h) The consummation of the Transactions will not, under any of the terms, conditions, or provisions of any Material Contract, (i) result in the creation of any Lien (other than a Permitted Lien) upon or, to the knowledge of the Company, give rise to any obligation on a Group Company to obtain any third party Consent or provide any notice to any Person with respect to any Company Owned IP or any other Intellectual Property used in and material to the Business by the Group Companies as currently conducted or (ii) trigger the release of, or create any obligation to release, source code for any Company Software.

(f) Officer's Certificate. SPAC shall have delivered to the Company a certificate signed by an officer of SPAC, dated as of the Closing Date, certifying that the conditions specified in Section 10.3(a), Section 10.3(b) and Section 10.3(c) have been fulfilled.

78

10.4 Frustration of Conditions. None of SPAC or the Company may rely on the failure of any condition set forth in this Article 10 to be satisfied if such failure was primarily caused by such Party's breach of any of its covenants or obligations set forth in this Agreement.

ARTICLE 11

TERMINATION/EFFECTIVENESS

11.1 Termination. This Agreement may be terminated and the Transactions abandoned at any time prior to the Closing, solely:

(a) by mutual written consent of SPAC, the Shareholders and the Company;

(b) by SPAC, if any of the representations or warranties set forth in Article 4 or Article 5 shall not be true and correct or if the Company or any Shareholder has failed to perform or has otherwise breached any of its covenants or agreements set forth in this Agreement (including an obligation to consummate the Closing) such that the condition to Closing set forth in either Section 10.2(a) or Section 10.2(b) would not be satisfied (assuming the Closing occurred as of such date) and the breach or breaches causing such representations or warranties not to be true and correct, or the failures to perform any covenant or agreement, as applicable, is (or are) not cured or cannot be cured within the earlier of (i) 30 days after written notice thereof is delivered to the Company by SPAC, and (ii) the Termination Date; provided, however, that SPAC is not then in breach of this Agreement so as to prevent the condition to Closing set forth in either Section 10.2(a) or Section 10.2(b) from being satisfied (assuming the Closing occurred as of such date);

(c) by the Shareholders, if any of the representations or warranties set forth in Article 6 shall not be true and correct or if SPAC has failed to perform any covenant or agreement on the part of SPAC set forth in this Agreement (including an obligation to consummate the Closing) such that the condition to Closing set forth in either Section 10.3(a) or Section 10.3(b) could not be satisfied (assuming the Closing occurred as of such date) and the breach or breaches causing such representations or warranties not to be true and correct, or the failures to perform any covenant or agreement, as applicable, is (or are) not cured or cannot be cured within the earlier of (i) 30 days after written notice thereof is delivered to SPAC by the Company and (ii) the Termination Date; provided, however, none of the Company or Shareholders is then in breach of this Agreement so as to prevent the condition to Closing set forth in Section 10.3(a) or Section 10.3(b) from being satisfied (assuming the Closing occurred as of such date);

(d) by either SPAC or the Shareholders, if the transactions contemplated by this Agreement shall not have been consummated on or prior to January 26, 2027 (the "Termination Date"); provided, that if on the Termination Date, the only conditions to Closing set forth in Article 10 that have not been satisfied or waived are those set forth in Section 10.1(e) (Registration Statement) or Section 10.1(b) (SPAC Shareholder Approval), the Termination Date shall be automatically extended to April 26, 2027 (the "Extended Termination Date"); provided further that (i) the right to terminate this Agreement pursuant to this Section 11.1(d) shall not be available to SPAC if SPAC's breach of any of its covenants or obligations under this Agreement, or any Ancillary Documents to which it is a party, shall have proximately caused the failure to consummate the transactions contemplated by this Agreement on or before the Termination Date, and (ii) the right to terminate this Agreement pursuant to this Section 11.1(d) shall not be available to the Key Shareholder if the Company's or any Shareholder's breach of any of its covenants or obligations under this Agreement, or any Ancillary Documents to which it is a party, shall have proximately caused the failure to consummate the transactions contemplated by this Agreement on or before the Termination Date;

(e) by either SPAC or the Shareholders, if any Governmental Authority shall have issued an Order or taken any other action permanently enjoining, restraining or otherwise prohibiting the Transactions and such Order or other action shall have become final and nonappealable; or

79

(f) by either SPAC or the Shareholders, if the SPAC Shareholders Meeting has been held (including any adjournment thereof), has concluded, SPAC's shareholders have duly voted and the Required SPAC Shareholder Approval was not obtained.

11.2 Effect of Termination. If this Agreement is terminated pursuant to Section 11.1, this Agreement shall thereupon become null and void and of no further force and effect and there shall be no Liability on the part of any Party to another Party, except that (a) the provisions of Section 9.5, Article 12, and this Section 11.2 shall remain in full force and effect and (b) nothing in this Section 11.2 shall be deemed to (i) release any Party from any Liability for any willful and material breach by such Party of any term of this Agreement prior to the date of termination or in respect of any Fraud Claim or (ii) impair the right of any Party to compel specific performance by any other Party of such other Party's obligations under this Agreement prior to the valid termination of this Agreement; provided, further, that nothing in this Section 11.2 shall, in any way, limit the waivers against the Trust Account as set forth in Section 12.16.

ARTICLE 12

Subject to the foregoing, this Agreement shall be binding upon and inure to the benefit of the Parties and their respective permitted successors and assigns. Any attempted assignment in violation of the terms of this Section 12.3 shall be null and void, ab initio.

12.4 Parties in Interest. This Agreement shall be binding upon and inure solely to the benefit of each Party and its successors and permitted assigns and, except as provided in Section 9.7, Section 12.18 and the two subsequent sentences of this Section 12.4, nothing in this Agreement, express or implied, is intended to or shall confer upon any other Person any rights, benefits or remedies of any nature whatsoever under or by reason of this Agreement.

12.6 Fees and Expenses. Except as otherwise set forth in this Agreement, all fees and expenses incurred in connection with this Agreement, the Ancillary Documents and the transactions contemplated hereby and thereby, including the fees and disbursements of counsel, financial advisors and accountants, shall be paid by the Party incurring such fees or expenses; provided, that if the Closing occurs, SPAC shall bear and pay all such fees and expenses of SPAC and the Company.

12.7 Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the law of any jurisdiction other than the State of Delaware (except that the laws of the Cayman Islands shall also apply to the Domestication).

12.8 Captions; Counterparts. The captions in this Agreement are for convenience only and shall not be considered a part of or affect the construction or interpretation of any provision of this Agreement. This Agreement and each Ancillary Document (including any of the closing deliverables contemplated hereby) may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Delivery of an executed counterpart of a signature page to this Agreement or any Ancillary Document (including any of the closing deliverables contemplated hereby) by e-mail or scanned pages shall be effective as delivery of a manually executed counterpart to this Agreement or any such Ancillary Document.

12.9 Schedules and Exhibits. All references herein to Schedules, Annexes and Exhibits shall be deemed references to such parts of this Agreement, unless the context shall otherwise require. Any disclosure made by a Party in the Schedules with reference to any section or schedule of this Agreement shall be deemed to be a disclosure with respect to all other sections or schedules to which such disclosure may apply solely to the extent the relevance of such disclosure is reasonably apparent on the face of the disclosure in such Schedule. Certain information set forth in the Schedules is included solely for informational purposes.

12.10 Entire Agreement. This Agreement (together with the Schedules, Annexes and Exhibits to this Agreement) and that certain Confidentiality Agreement, dated as of May 22, 2026, between SPAC and the Company (as amended, modified or supplemented from time to time, the "Confidentiality Agreement"), constitute the entire agreement among the Parties relating to the Transactions and supersede any other agreements, whether written or oral, that may have been made or entered into by or among any of the Parties or any of their respective Subsidiaries relating to the Transactions. No representations, warranties, covenants, understandings, agreements, oral or otherwise, relating to the transactions contemplated by this Agreement exist between the Parties except as expressly set forth or referenced in this Agreement and the Confidentiality Agreement.

12.11 Amendments. This Agreement may be amended or modified in whole or in part, only by a duly authorized agreement in writing executed in the same manner as this Agreement and which makes reference to this Agreement. The approval of this Agreement by the shareholders of any of the Parties shall not restrict the ability of the board of directors (or other body performing similar functions) of any of the Parties to terminate this Agreement in accordance with Section 11.1 or to cause such Party to enter into an amendment to this Agreement pursuant to this Section 12.11.

82

12.12 Extension; Waiver. The Company prior to the Closing, and the Company and the Sponsor after the Closing may (a) extend the time for the performance of any of the obligations or other acts of SPAC set forth herein, (b) waive any inaccuracies in the representations and warranties of SPAC set forth herein or (c) waive compliance by SPAC with any of the agreements or conditions set forth herein. SPAC may (i) extend the time for the performance of any of the obligations or other acts of the Company set forth herein, (ii) waive any inaccuracies in the representations and warranties of the Company set forth herein or (iii) waive compliance by the Company with any of the agreements or conditions set forth herein. Any agreement on the part of any such Party to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such Party. Any waiver of any term or condition shall not be construed as a waiver of any subsequent breach or a subsequent waiver of the same term or condition, or a waiver of any other term or condition of this Agreement. The failure of any Party to assert any of its rights hereunder shall not constitute a waiver of such rights.

12.13 Severability. If any provision of this Agreement is held invalid or unenforceable by any court of competent jurisdiction, the other provisions of this Agreement shall remain in full force and effect. The Parties further agree that if any provision contained herein is, to any extent, held invalid or unenforceable in any respect under the Laws governing this Agreement, they shall take any actions necessary to render the remaining provisions of this Agreement valid and enforceable to the fullest extent permitted by Law and, to the extent necessary, shall amend or otherwise modify this Agreement to replace any provision contained herein that is held invalid or unenforceable with a valid and enforceable provision giving effect to the intent of the Parties.

12.14 Jurisdiction; Waiver of Trial by Jury. Any Action based upon, arising out of or related to this Agreement or the Transactions shall be brought in federal and state courts located in the State of Delaware, and each of the Parties irrevocably submits to the exclusive jurisdiction of each such court in any such Action, waives any objection it may now or hereafter have to personal jurisdiction, venue or to convenience of forum, agrees that all claims in respect of the Action shall be heard and determined only in any such court, and agrees not to bring any Action arising out of or relating to this Agreement or the Transactions in any other court. Nothing herein contained shall be deemed to affect the right of any Party to serve process in any manner permitted by Law or to commence legal proceedings or otherwise proceed against any other Party in any other jurisdiction, in each case, to enforce judgments obtained in any Action brought pursuant to this Section 12.14. EACH OF THE PARTIES HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY ACTION BASED UPON, ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS.

12.15 Enforcement. The Parties agree that irreparable damage for which monetary damages, even if available, would not be an adequate remedy, would occur in the event that the Parties do not perform their obligations under the provisions of this Agreement or any other Transaction Agreement in accordance with its specified terms or otherwise breach such provisions. The Parties acknowledge and agree that (a) the Parties shall be entitled to an injunction, specific performance, or other equitable relief, to prevent breaches of any Transaction Agreement and to enforce specifically the terms and provisions hereof and thereof, without proof of damages, prior to the valid termination of this Agreement in accordance with Section 11.1, this being in addition to any other remedy to which they are entitled under any Transaction Agreement or under applicable Law, and (b) the right of specific enforcement is an integral part of the transactions contemplated by this Agreement and without that right, none of the Parties would have entered into this Agreement. Each Party agrees that it will not oppose the granting of specific performance and other equitable relief on the basis that the other Parties have an adequate remedy at Law or that an award of specific performance is not an appropriate remedy for any reason at Law or equity. The Parties acknowledge and agree that any Party seeking an injunction to prevent breaches of any Transaction Agreement and to enforce specifically the terms and provisions of any Transaction Agreement in accordance with this Section 12.15 shall not be required to provide any bond or other security in connection with any such injunction.

83

12.16 Trust Account Waiver. Reference is made to the final prospectus of SPAC, filed with the SEC (File No. 333-294549) on May 20, 2026 (the "Prospectus"). The Company acknowledges, agrees and understands that SPAC 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 SPAC's public shareholders (the "Public Shareholders"), and SPAC may disburse monies from the Trust Account only in the express circumstances described in the Prospectus. For and in consideration of SPAC entering into this Agreement, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Company hereby agrees on behalf of itself and its Representatives that, notwithstanding the foregoing or anything to the contrary in this Agreement, none of the Company nor any of its Representatives does now or shall at any time hereafter have any right, title, interest or claim of any kind in or to any monies in the Trust Account or distributions therefrom, or make any claim against the Trust Account (including any distributions therefrom), regardless of whether such claim arises as a result of, in connection with or relating in any way to, this Agreement or any proposed or actual business relationship between SPAC or any of its Representatives, on the one hand, and, the Company or any of its Representatives, on the other hand, or any other matter, 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 "Trust Account Released Claims"). The Company (on its own behalf and on behalf of its Representatives) hereby irrevocably waives any Trust Account Released Claims that it or any of its Representatives may have against the Trust Account (including any distributions therefrom) now or in the future as a result of, or arising out of, any negotiations, or Contracts with SPAC or its Representatives and will not seek recourse against the Trust Account (including any distributions therefrom) for any reason whatsoever (including for an alleged breach of any agreement with SPAC or its Affiliates).

12.17 Conflicts and Privilege.

(a) Each of the Parties, on behalf of their respective successors and assigns, hereby agree that, in the event a dispute with respect to this Agreement or the transactions contemplated hereby arises after the Closing between or among (x) the Sponsor, the shareholders or holders of other equity interests of SPAC or the Sponsor and/or any of their respective directors, members, partners, officers, employees or Affiliates (other than the Company) prior to the Closing (collectively, the "Sponsor Group"), on the one hand, and (y) the Company and/or any member of the OHB Group, on the other hand, any legal counsel, including Cooley LLP ("Cooley") and Maples and Calder (Cayman) LLP that represented SPAC and/or the Sponsor prior to the Closing may represent the Sponsor and/or any other member of the Sponsor Group, in such dispute even though the interests of such Persons may be directly adverse to the Company, and even though such counsel may have represented SPAC in a matter substantially related to such dispute, or may be handling ongoing matters for SPAC and/or the Sponsor. Each of the Parties, on behalf of their respective successors and assigns, further agree that, as to all legally privileged communications prior to the Closing (made in connection with the negotiation, preparation, execution, delivery and performance under, or any dispute or Action arising out of or relating to, this Agreement, any Transaction Agreements or the transactions contemplated hereby or thereby) between or among SPAC, the Sponsor and/or any other member of the Sponsor Group, on the one hand, and Cooley, on the other hand, the attorney/client privilege and the expectation of client confidence shall survive the Closing and belong to the Sponsor Group after the Closing, and shall not pass to or be claimed or controlled by SPAC or the Company. Notwithstanding the foregoing, any privileged communications or information shared by the Company prior to the Closing with SPAC or the Sponsor under a common interest agreement shall remain the privileged communications or information of the Company.

(b) Each of the Parties, on behalf of their respective successors and assigns, hereby agree that, in the event a dispute with respect to this Agreement or the transactions contemplated hereby arises after the Closing between or among (x) the Shareholders or holders of other equity interests of the Company and/or any of their respective directors, members, partners, officers, employees or Affiliates prior to the Closing (collectively, the "OHB Group"), on the one hand, and (y) SPAC and/or any member of the Sponsor Group, on the other hand, any legal counsel, including Goodwin Procter LLP ("Goodwin") that represented the Company prior to the Closing may represent any member of the OHB Group in such dispute even though the interests of such Persons may be directly adverse to SPAC, and even though such counsel

84

may have represented the Company in a matter substantially related to such dispute, or may be handling ongoing matters for SPAC or the Company, further agree that, as to all legally privileged communications prior to the Closing (made in connection with the negotiation, preparation, execution, delivery and performance under, or any dispute or Action arising out of or relating to, this Agreement, any Transaction Agreements or the transactions contemplated hereby or thereby) between or among the Company and/or any member of the OHB Group, on the one hand, and Goodwin, on the other hand, the attorney/client privilege and the expectation of client confidence shall survive the Closing and belong to the OHB Group after the Closing, and shall not pass to or be claimed or controlled by SPAC. Notwithstanding the foregoing, any privileged communications or information shared by SPAC prior to the Closing with the Company under a common interest agreement shall remain the privileged communications or information of SPAC.

12.18 Placement Agents. Each of Leerink Partners LLC, UBS Securities LLC, Wells Fargo Securities, LLC and LifeSci Capital LLC (together, the "Placement Agents" and each a "Placement Agent") shall be entitled to rely on the representations and warranties of the Company and the SPAC set forth in Article 4 and Article 6, respectively, as if such representations and warranties were made specifically to the Placement Agents as third-party beneficiaries with respect to this Agreement.

OF

[•]

ARTICLE I

The name of the Corporation is [•].

ARTICLE II

The address of the Corporation's registered office in the State of Delaware is [•]. The name of its registered agent at such address is [•].

ARTICLE III

The purpose of the Corporation is to engage in any lawful act or activity for which corporations may be organized under the DGCL.

ARTICLE IV

CAPITAL STOCK

The total number of shares of capital stock which the Corporation shall have authority to issue is [•], of which (i) [•] shares shall be a class designated as common stock, par value $0.0001 per share (the "Common Stock"), and (ii) [•] shares shall be a class designated as preferred stock, par value $0.0001 per share (the "Preferred Stock").

Except as otherwise provided in any certificate of designation of any series of Preferred Stock, the number of authorized shares of the class of Common Stock or Preferred Stock may be increased or decreased (but not below the number of shares of such class then outstanding) by the affirmative vote of the holders of a majority in voting power of the outstanding shares of capital stock of the Corporation entitled to vote thereon irrespective of the provisions of Section 242(b)(2) of the DGCL, and no vote of the holders of any of the Common Stock or the Preferred Stock voting separately as a class shall be required therefor. For the avoidance of doubt, the elimination and reduction of the voting requirements of Section 242 of the DGCL, as permitted by Section 242(d) of the DGCL, shall apply to any amendments to the Amended and Restated Certificate of Incorporation (the "Certificate").

The powers, preferences and rights of, and the qualifications, limitations and restrictions upon, each class or series of stock shall be determined in accordance with, or as set forth below in, this Article IV.

A. COMMON STOCK

Subject to all the rights, powers and preferences of the Preferred Stock and except as provided by law or in this Certificate (including any certificate of designation of any series of Preferred Stock):

(a) the holders of the Common Stock shall have the exclusive right to vote for the election of directors of the Corporation (the "Directors") and on all other matters requiring stockholder action, each outstanding share entitling the holder thereof to one vote on each matter properly submitted to the stockholders of the Corporation for their vote; provided, however, that, except as otherwise required by law, holders of Common Stock, as such, shall not be entitled to vote on any amendment to this Certificate (including any amendment to a certificate of designation of any series of Preferred Stock) that alters or changes the powers, preferences, rights or other terms of one or more outstanding series of Preferred Stock if the holders of such affected series of Preferred Stock are entitled to vote, either separately or together with the holders of one or more other such series, on such amendment pursuant to this Certificate (including any certificate of designation of any series of Preferred Stock) or pursuant to the DGCL;

(b) dividends may be declared and paid or set apart for payment upon the shares of Common Stock out of any assets or funds of the Corporation legally available for the payment of dividends, but only when, as and if declared by the Board of Directors of the Corporation (the "Board") or any authorized committee thereof; and

(c) upon the voluntary or involuntary liquidation, dissolution or winding up of the Corporation, the net assets of the Corporation shall be distributed pro rata to the holders of the Common Stock.

B. PREFERRED STOCK

The Board of Directors or any authorized committee thereof is expressly authorized to provide by resolution or resolutions for, out of the unissued shares of Preferred Stock, the issuance of the shares of Preferred Stock in one or more series of such stock, and by filing a certificate of designation pursuant to applicable law of the State of Delaware, to establish or change from time to time the number of shares of each such series, and to fix the designations, powers, including voting powers, full or limited, or no voting powers, preferences and the relative, participating, optional or other special rights of the shares of each series and any qualifications, limitations and restrictions thereof, all to the fullest extent now or hereafter permitted by the DGCL. The powers, preferences and relative, participating, optional and other special rights of each such series of Preferred Stock, and the qualifications, limitations or restrictions thereof, if any, may differ from those of any and all other series at any time outstanding. Without limiting the generality of the foregoing, the resolution or resolutions providing for the issuance of any series of Preferred Stock may provide that such series shall be superior or rank equally or be junior to any other series of Preferred Stock to the extent permitted by law.

3

ARTICLE V

STOCKHOLDER ACTION

1. Action without Meeting. Subject to the rights, if any, of the holders of shares of any series of Preferred Stock, any action required or permitted to be taken by the stockholders of the Corporation at any annual or special meeting of stockholders of the Corporation must be effected at a duly called annual or special meeting of stockholders and may not be taken or effected by a consent of stockholders in lieu thereof.

2. Special Meetings. Except as otherwise required by statute and subject to the rights, if any, of the holders of shares of any series of Preferred Stock, special meetings of the stockholders of the Corporation may be called only by the Board of Directors, and special meetings of stockholders may not be called by any other person or persons. Only those matters set forth in the notice of the special meeting may be considered or acted upon at a special meeting of stockholders of the Corporation.

ARTICLE VI

DIRECTORS

1. General. The business and affairs of the Corporation shall be managed by or under the direction of the Board of Directors except as otherwise provided herein or required by law.

2. Number of Directors; Term of Office. Except as otherwise provided for or fixed pursuant to the provisions of Article IV (including any certificate of designation with respect to any series of Preferred Stock) and this Article VI relating to the rights of the holders of any series of Preferred Stock to elect additional Directors, the number of directors of the Corporation (the "Directors") shall be fixed solely and exclusively by resolution duly adopted from time to time by the Board of Directors. The Directors, other than those who may be elected by the holders of any series of Preferred Stock, shall be classified, with respect to the term for which they severally hold office, into three classes. The term of office of the initial Class I Directors shall expire at the first regularly-scheduled annual meeting of stockholders following the initial effectiveness of this certificate. The term of office of the initial Class II Directors shall expire at the second annual meeting of stockholders following the initial effectiveness of this certificate. The term of office of the initial Class III Directors shall expire at the third annual meeting of stockholders following the initial effectiveness of this certificate. The Board of Directors is authorized to assign members of the Board of Directors already in office to such classes at the time the classification of the Board of Directors becomes effective. At each annual meeting of stockholders, Directors elected to succeed those Directors whose terms expire shall be elected for a term of office to expire at the third succeeding annual meeting of stockholders after their election. Notwithstanding the foregoing, the Directors elected to each class shall hold office

4

until their successors are duly elected and qualified or until their earlier resignation, death, disqualification or removal. No decrease in the number of Directors shall shorten the term of any incumbent Director. There shall be no cumulative voting in the election of Directors. Election of Directors need not be by written ballot unless the Bylaws of the Corporation so provide.

Notwithstanding the foregoing, whenever, pursuant to the provisions of Article IV of this Certificate, the holders of any one or more series of Preferred Stock shall have the right, voting separately as a series or together with holders of other such series, to elect additional Directors, the election, term of office, filling of vacancies and other features of such directorships shall be governed by the terms of this Certificate, including any certificate of designation applicable to such series of Preferred Stock. During any period when the holders of any series of Preferred Stock, voting separately as a series or together with one or more series, have the right to elect additional Directors, then upon commencement and for the duration of the period during which such right continues: (i) the then otherwise total authorized number of Directors shall automatically be increased by such specified number of Directors, and the holders of such Preferred Stock shall be entitled to elect the additional Directors so provided for or fixed pursuant to said provisions, and (ii) each such additional Director shall serve until such Director's successor shall have been duly elected and qualified, or until such Director's right to hold such office terminates pursuant to said provisions, whichever occurs earlier, subject to such Director's earlier death, resignation, retirement, disqualification or removal. Notwithstanding any other provision of this Certificate of Incorporation, except as otherwise provided by the Board in the resolution or resolutions establishing such series, whenever the holders of any series of Preferred Stock having such right to elect additional Directors are divested of such right pursuant to the provisions of such stock, the terms of office of all such additional Directors elected by the holders of such stock, or elected to fill any vacancies resulting from the death, resignation, disqualification or removal of such additional Directors, shall forthwith terminate (in which case each such Director shall thereupon cease to be qualified as, and shall cease to be, a Director) and the total authorized number of Directors shall automatically be reduced accordingly.

3. Vacancies and Newly Created Directorships. Subject to the rights, if any, of the holders of any series of Preferred Stock to elect Directors and to fill vacancies in the Board of Directors relating thereto, any and all vacancies and newly created directorships in the Board of Directors, however occurring, including, without limitation, by reason of an increase in the size of the Board of Directors, or the death, resignation, disqualification or removal of a Director, shall be filled solely and exclusively by the affirmative vote of a majority of the remaining Directors then in office, even if less than a quorum of the Board of Directors, or by a sole remaining Director, and not by the stockholders. Any Director appointed in accordance with the preceding sentence shall hold office for the remainder of the full term of the class of Directors in which the new directorship was created or the vacancy occurred and until such Director's successor shall have been duly elected and qualified or until such Director's earlier resignation, disqualification, death or removal. Subject to the rights, if any, of the holders of any series of Preferred Stock to elect Directors, when the number of Directors is increased or decreased, the Board of Directors shall, subject to Article VI.3 hereof, determine the class or classes to which the increased or decreased number of Directors shall be apportioned. In the event of a vacancy in the Board of Directors, the remaining Directors, except as otherwise provided by law, shall exercise the powers of the full Board of Directors until the vacancy is filled.

5

4. Removal. Subject to the rights, if any, of any series of Preferred Stock to elect Directors and to remove any Director whom the holders of any such series have the right to elect, any Director may be removed from office (i) only for cause and (ii) only by the affirmative vote of the holders not less than two-thirds (2/3) of the voting power of the outstanding shares of capital stock then entitled to vote at an election of Directors.

ARTICLE VII

LIMITATION OF LIABILITY

If the DGCL is amended after the effective date of this Certificate to authorize corporate action further eliminating or limiting the personal liability of Officers, then the liability of an Officer of the Corporation shall be eliminated or limited to the fullest extent permitted by the DGCL, as so amended. For purposes of this Article VII, "Officer" shall mean an individual who has been duly appointed as an officer of the Corporation and who, at the time of an act or omission as to which liability is asserted, is deemed to have consented to service by the delivery of process to the registered agent of the Corporation as contemplated by 10 Del.

The Board of Directors or a designated committee thereof shall have the power to determine whether a nomination or any business proposed to be brought before the meeting was made in accordance with the provisions of this Bylaw. If neither the Board of Directors nor such designated committee makes a determination as to whether any stockholder proposal or nomination was made in accordance with the provisions of this Bylaw, the chair of the meeting (as defined in Section 9 of this Article I) shall have the power and duty to determine whether the stockholder proposal or nomination was made in accordance with the provisions of this Bylaw.

(3) Notwithstanding the foregoing provisions of this Article I, Section 2, if the nominating or proposing stockholder (or a qualified representative of the stockholder) does not appear at the Annual Meeting to present a nomination or any business, such nomination or business shall be disregarded, notwithstanding that proxies in respect of such vote may have been received by the Corporation. For purposes of this Article I, Section 2, to be considered a qualified representative of the proposing stockholder, a person must be authorized by a written instrument executed by such stockholder or an electronic transmission delivered by such stockholder to act for such stockholder as proxy at the meeting of stockholders, and such person must produce such written instrument or electronic transmission, or a reliable reproduction of the written instrument or electronic transmission, to the chair of the meeting at the meeting of stockholders.

(4) For purposes of this Bylaw, "public announcement" shall mean disclosure in a press release reported by the Dow Jones News Service, Associated Press or comparable national news service or in a document publicly filed by the Corporation with the Securities and Exchange Commission pursuant to Section 13, 14 or 15(d) of the Exchange Act.

(5) Notwithstanding the foregoing provisions of this Bylaw, a stockholder shall also comply with all applicable requirements of the Exchange Act and the rules and regulations thereunder, including, but not limited to, Rule 14a-19 of the Exchange Act, with respect to the matters set forth in this Bylaw. If a stockholder fails to comply with any applicable requirements of the Exchange Act, including, but not limited to, Rule 14a-19 promulgated thereunder, such stockholder's proposed nomination or proposed business shall be deemed to have not been made in compliance with this Bylaw and shall be disregarded.

(6) Further notwithstanding the foregoing provisions of this Bylaw, unless otherwise required by law, (i) no Proposing Person shall solicit proxies in support of director nominees other than the Corporation's nominees unless such Proposing Person has complied with Rule 14a-19 promulgated under the Exchange Act in connection with the solicitation of such proxies, including the provision to the Corporation of notices required thereunder with timely notice and (ii) if any Proposing Person (A) provides notice pursuant to Rule 14a-19(b) promulgated under the Exchange Act, (B) subsequently fails to comply with the requirements of Rule 14a-19(a)(2) or Rule 14a-19(a)(3) promulgated under the Exchange Act, including the provision to the Corporation of notices required thereunder with timely notice and (C) no other Proposing Person has provided notice pursuant to, and in compliance with, Rule 14a-19 under the Exchange Act that it intends to solicit proxies in support of the election of such proposed nominee in accordance with Rule 14a-19(b) under the Exchange Act, then such proposed nominee shall be disqualified from nomination, the Corporation shall disregard the nomination of such proposed nominee and no vote on the election of such proposed nominee shall occur. Upon request by the Corporation, if any Proposing Person provides notice pursuant to Rule 14a-19(b) promulgated under the Exchange Act, such Proposing Person shall deliver to the Corporation, no later than five (5) business days prior to the applicable meeting date, reasonable evidence that it has met the requirements of Rule 14a-19(a)(3) promulgated under the Exchange Act.

Nominations of persons for election to the Board of Directors and stockholder proposals of other business shall not be brought before a special meeting of stockholders to be considered by the stockholders unless such special meeting is held in lieu of an annual meeting of stockholders in accordance with Article I, Section 1 of these Bylaws, in which case such special meeting in lieu thereof shall be deemed an Annual Meeting for purposes of these Bylaws and the provisions of Article I, Section 2 of these Bylaws shall govern such special meeting.

(c) Notice of an Annual Meeting or special meeting of stockholders need not be given to a stockholder if a waiver of notice is executed, or waiver of notice by electronic transmission is provided, before or after such meeting by such stockholder or if such stockholder attends such meeting, unless such attendance is for the express purpose of objecting at the beginning of the meeting to the transaction of any business because the meeting was not lawfully called or convened.

(d) The Board of Directors may postpone and reschedule or cancel any previously scheduled Annual Meeting or special meeting of stockholders and any record date with respect thereto, regardless of whether any notice or public disclosure with respect to any such meeting has been sent or made pursuant to Section 2 of this Article I or otherwise. In no event shall the public announcement of an adjournment, postponement or rescheduling of any previously scheduled meeting of stockholders commence a new time period for the giving of a stockholder's notice under this Article I.

(e) When any meeting is convened, the chair of the meeting or the stockholders present or represented by proxy at such meeting may adjourn the meeting from time to time for any reason, regardless of whether a quorum is present, to reconvene at any other time and at any place at which a meeting of stockholders may be held under these Bylaws. When any Annual Meeting or special meeting of stockholders is adjourned to another hour, date or place (including an adjournment taken to address a technical failure to convene or continue a meeting using remote communication), notice need not be given of the adjourned meeting if the time, place, if any, thereof and the means of remote communications, if any, by which stockholders and proxy holders may be deemed to be present in person and vote at such adjourned meeting are (i) announced at the meeting at which the adjournment is taken, (ii) displayed, during the time scheduled for the meeting, on the same electronic network used to enable stockholders and proxy holders to participate in the meeting by means of remote communication or (iii) set forth in the notice of meeting given in accordance with this Section 4; provided, however, that if the adjournment is for more than thirty (30) days from the meeting date, or if after the adjournment a new record date is fixed for the adjourned meeting, notice of the adjourned meeting and the means of remote communications, if any, by which stockholders and proxyholders may be deemed to be present in person and vote at such adjourned meeting shall be given to each stockholder of record entitled to vote thereat and each stockholder who, by law or under the Certificate of Incorporation of the Corporation (as the same may hereafter be amended and/or restated, the "Certificate") or these Bylaws, is entitled to such notice.

SECTION 5. Quorum. Except as otherwise provided by law, the certificate of incorporation or these Bylaws, at each meeting of stockholders, the presence in person or by remote communication, if applicable, or represented by proxy, of the holders of a majority in voting power of the outstanding shares of stock entitled to vote at the meeting shall be necessary and sufficient to constitute a quorum. If less than a quorum is present at a meeting, the chair of the meeting or the holders of voting stock, by the affirmative vote of a majority of the voting power present in person or by proxy and entitled to vote thereon, may adjourn the meeting from time to time, and the meeting may be held as adjourned without further notice, except as otherwise provided in Section 4 of this Article I. At such adjourned meeting at which a quorum is present, any business may be transacted which might have been transacted at the meeting as originally noticed. The stockholders present at a duly constituted meeting may continue to transact business until adjournment, notwithstanding the withdrawal of enough stockholders to leave less than a quorum.

Stockholders shall have one vote for each share of stock entitled to vote owned by them of record according to the stock ledger of the Corporation as of the record date, unless otherwise provided by law or by the Certificate. Stockholders may vote either (i) in person, (ii) by written proxy or (iii) by a transmission permitted by Section 212(c) of the DGCL. Any copy, facsimile telecommunication or other reliable reproduction of the writing or transmission permitted by Section 212(c) of the DGCL may be substituted for or used in lieu of the original writing or transmission for any and all purposes for which the original writing or transmission could be used, provided that such copy, facsimile telecommunication or other reproduction shall be a complete reproduction of the entire original writing or transmission. Proxies shall be filed in accordance with the procedures established for the meeting of stockholders. A proxy with respect to stock held in the name of two or more persons shall be valid if executed by or on behalf of any one of them unless at or prior to the exercise of the proxy the Corporation receives a specific written notice to the contrary from any one of them. In the event the Corporation receives proxies for disqualified or withdrawn nominees for the Board of Directors, such votes for such disqualified or withdrawn nominees in the proxies will be treated as abstentions.

(b) Any stockholder directly or indirectly soliciting proxies from other stockholders must use a proxy card color other than white, which shall be reserved for the exclusive use by the Board of Directors.

SECTION 7. Action at Meeting. When a quorum is present at any meeting of stockholders, any matter before any such meeting (other than an election of a director or directors) shall be decided by a majority of the votes properly cast for and against such matter, except where a larger vote is required by law, by the Certificate or by these Bylaws. Any election of directors by stockholders shall be determined by a plurality of the votes properly cast on the election of directors.

SECTION 8. Stockholder Lists. The Corporation shall prepare, no later than the tenth (10th) day before each Annual Meeting or special meeting of stockholders, a complete list of the stockholders entitled to vote at the meeting, arranged in alphabetical order, and showing the address of each stockholder and the number of shares registered in the name of each stockholder; provided, however, that if the record date for determining the stockholders entitled to vote is less than ten (10) days before the meeting date, the list shall reflect the stockholders entitled to vote as of the tenth (10th) day before the meeting date. Such list shall be open to the examination of any stockholder for any purpose germane to the meeting for a period of ten (10) days ending on the day before the meeting date in the manner provided by law.

SECTION 9. Conduct of Meeting. The Board of Directors may adopt by resolution such rules, regulations and procedures for the conduct of any meeting of stockholders as it shall deem appropriate. Except to the extent inconsistent with rules, regulations and procedures adopted by the Board of Directors, the chair of the meeting shall have the right to prescribe such

11

rules, regulations and procedures and to do all such acts, as, in the judgment of such chair, are necessary, appropriate or convenient for the proper conduct of the meeting. Such rules, regulations or procedures, whether adopted by the Board of Directors or the chair of the meeting, may include, without limitation, the following: (a) the establishment of an agenda for the meeting; (b) rules and procedures for maintaining order at the meeting and the safety of those present at the meeting; (c) limitations on attendance at or participation in the meeting to stockholders of record of the Corporation, their duly authorized and constituted proxies, or such other persons as the chair of the meeting shall determine; (d) restrictions on entry to the meeting after the time fixed for the commencement thereof; (e) the determination of the circumstances in which any person may make a statement or ask questions and limitations on the time allotted to questions or comments; (f) the determination of when the polls shall open and close for any given matter to be voted on at the meeting; (g) the exclusion or removal of any stockholders or any other individual who refuses to comply with meeting rules, regulations, or procedures; (h) restrictions on the use of audio and video recording devices, cell phones and other electronic devices; (i) rules, regulations and procedures for compliance with any federal, state or local laws or regulations (including those concerning safety, health or security); (j) procedures (if any) requiring attendees to provide the Corporation advance notice of their intent to attend the meeting; and (k) rules, regulations or procedures regarding the participation by means of remote communication of stockholders and proxy holders not physically present at a meeting, whether such meeting is to be held at a designated place or solely by means of remote communication. The chair of the meeting shall be: (i) such person as the Board of Directors shall have designated to preside over all meetings of the stockholders; (ii) if the Board of Directors has not so designated such a chair of the meeting or if the chair of the meeting is unable to so preside or is absent, then the Chairperson of the Board, if one is elected; (iii) if the Board of Directors has not so designated a chair of the meeting and there is no Chairperson of the Board, or if the chair of the meeting or the Chairperson of the Board is unable to so preside or is absent, then the Chief Executive Officer, if one is elected; or (iv) in the absence or inability to serve of any of the aforementioned persons, the President of the Corporation. Unless and to the extent determined by the Board of Directors or the chair of the meeting, the chair of the meeting shall not be obligated to adopt or follow any technical, formal or parliamentary rules or principles of procedure. In the absence of the Secretary of the Corporation, the secretary of the meeting shall be such person as the chair of the meeting appoints.

SECTION 10. Inspectors of Elections. The Corporation shall, in advance of any meeting of stockholders, appoint one or three inspectors to act at the meeting and make a written report thereof. The Corporation may designate one or more persons as alternate inspectors to replace any inspector who fails to act. If no inspector or alternate is able to act at a meeting of stockholders, the chair of the meeting officer shall appoint one or more inspectors to act at the meeting. Any inspector may, but need not, be an officer, employee or agent of the Corporation. Each inspector, before entering upon the discharge of his or her duties, shall take and sign an oath faithfully to execute the duties of inspector with strict impartiality and according to the best of his or her ability. The inspectors shall perform such duties as are required by the DGCL, including the counting of all votes and ballots. The inspectors may appoint or retain other persons or entities to assist the inspectors in the performance of the duties of the inspectors. The chair of the meeting may review all determinations made by the inspectors, and in so doing the chair of the meeting shall be entitled to exercise his or her sole judgment and discretion and he or she shall not be bound by any determinations made by the inspectors. All determinations by the inspectors and, if applicable, the chair of the meeting, shall be subject to further review by any court of competent jurisdiction.

SECTION 3. Stock Transfer Agreements. The Corporation shall have power to enter into and perform any agreement with any number of stockholders of any one or more classes of stock of the Corporation to restrict the transfer of shares of stock of the Corporation of any one or more classes owned by such stockholders in any manner not prohibited by the DGCL.

SECTION 2. Indemnification of Directors and Officers.

(a) Subject to the operation of Section 4 of this Article V, each Director and Officer shall be indemnified and held harmless by the Corporation to the fullest extent authorized by the DGCL, as the same exists or may hereafter be amended (but, in the case of any such amendment,

20

only to the extent that such amendment permits the Corporation to provide broader indemnification rights than such law permitted the Corporation to provide prior to such amendment), and to the extent authorized in this Section 2.

(1) Actions, Suits and Proceedings Other than By or In the Right of the Corporation. Each Director and Officer shall be indemnified and held harmless by the Corporation against any and all Expenses and Liabilities that are incurred or paid by such Director or Officer or on such Director's or Officer's behalf in connection with any Proceeding or any claim, issue or matter therein (other than an action by or in the right of the Corporation), which such Director or Officer is, or is threatened to be made, a party to or participant in by reason of such Director's or Officer's Corporate Status, if such Director or Officer acted in good faith and in a manner such Director or Officer reasonably believed to be in or not opposed to the best interests of the Corporation and, with respect to any criminal proceeding, had no reasonable cause to believe his or her conduct was unlawful.

(2) Actions, Suits and Proceedings By or In the Right of the Corporation. Each Director and Officer shall be indemnified and held harmless by the Corporation against any and all Expenses that are incurred by such Director or Officer or on such Director's or Officer's behalf in connection with any Proceeding or any claim, issue or matter therein by or in the right of the Corporation, which such Director or Officer is, or is threatened to be made, a party to or participant in by reason of such Director's or Officer's Corporate Status, if such Director or Officer acted in good faith and in a manner such Director or Officer reasonably believed to be in or not opposed to the best interests of the Corporation; provided, however, that no indemnification shall be made under this Section 2(a)(2) in respect of any claim, issue or matter as to which such Director or Officer shall have been finally adjudged by a court of competent jurisdiction to be liable to the Corporation, unless, and only to the extent that, the Court of Chancery of the State of Delaware or another court in which such Proceeding was brought shall determine upon application that, despite adjudication of liability, but in view of all the circumstances of the case, such Director or Officer is fairly and reasonably entitled to indemnification for such Expenses that such court deems proper.

(3) Survival of Rights. The rights of indemnification provided by this Section 2 shall continue as to a Director or Officer after he or she has ceased to be a Director or Officer and shall inure to the benefit of his or her heirs, executors, administrators and personal representatives.

(4) Actions by Directors or Officers. Notwithstanding the foregoing, the Corporation shall indemnify any Director or Officer seeking indemnification in connection with a Proceeding initiated by such Director or Officer only if such Proceeding (including any parts of such Proceeding not initiated by such Director or Officer) was authorized in advance by the Board of Directors, unless such Proceeding was brought to enforce such Officer's or Director's rights to indemnification or, in the case of Directors, advancement of Expenses under these Bylaws in accordance with the provisions set forth herein.

21

SECTION 3. Indemnification of Non-Officer Employees. Subject to the operation of Section 4 of this Article V, each Non-Officer Employee may, in the discretion of the Board of Directors, be indemnified by the Corporation to the fullest extent authorized by the DGCL, as the same exists or may hereafter be amended, against any or all Expenses and Liabilities that are incurred by such Non-Officer Employee or on such Non-Officer Employee's behalf in connection with any threatened, pending or completed Proceeding, or any claim, issue or matter therein, which such Non-Officer Employee is, or is threatened to be made, a party to or participant in by reason of such Non-Officer Employee's Corporate Status, if such Non-Officer Employee acted in good faith and in a manner such Non-Officer Employee reasonably believed to be in or not opposed to the best interests of the Corporation and, with respect to any criminal proceeding, had no reasonable cause to believe his or her conduct was unlawful. The rights of indemnification provided by this Section 3 shall exist as to a Non-Officer Employee after he or she has ceased to be a Non-Officer Employee and shall inure to the benefit of his or her heirs, personal representatives, executors and administrators. Notwithstanding the foregoing, the Corporation may indemnify any Non-Officer Employee seeking indemnification in connection with a Proceeding initiated by such Non-Officer Employee only if such Proceeding was authorized in advance by the Board of Directors.

SECTION 4. Determination. Unless ordered by a court, no indemnification shall be provided pursuant to this Article V to a Director, to an Officer or to a Non-Officer Employee unless a determination shall have been made that such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the Corporation and, with respect to any criminal Proceeding, such person had no reasonable cause to believe his or her conduct was unlawful. Such determination shall be made by (a) a majority vote of the Disinterested Directors, even though less than a quorum of the Board of Directors, (b) a committee comprised of Disinterested Directors, such committee having been designated by a majority vote of the Disinterested Directors (even though less than a quorum), (c) if there are no such Disinterested Directors, or if a majority of Disinterested Directors so directs, by independent legal counsel in a written opinion or (d) by the stockholders of the Corporation.

SECTION 5. Advancement of Expenses to Directors Prior to Final Disposition.

(a) The Corporation shall advance all Expenses incurred by or on behalf of any Director in connection with any Proceeding in which such Director is involved by reason of such Director's Corporate Status within thirty (30) days after the receipt by the Corporation of a written statement from such Director requesting such advance or advances from time to time, whether prior to or after final disposition of such Proceeding. Such statement or statements shall reasonably evidence the Expenses incurred by such Director and shall be preceded or accompanied by an undertaking by or on behalf of such Director to repay any Expenses so advanced if it shall ultimately be determined that such Director is not entitled to be indemnified against such Expenses. Notwithstanding the foregoing, the Corporation shall advance all Expenses incurred by or on behalf of any Director seeking advancement of expenses hereunder in connection with a Proceeding initiated by such Director only if such Proceeding (including any parts of such Proceeding not initiated by such Director) was (i) authorized by the Board of Directors or (ii) brought to enforce such Director's rights to indemnification or advancement of Expenses under these Bylaws.

22

(b) If a claim for advancement of Expenses hereunder by a Director is not paid in full by the Corporation within thirty (30) days after receipt by the Corporation of documentation of Expenses and the required undertaking, such Director may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim and, if successful in whole or in part, such Director shall also be entitled to be paid the expenses of prosecuting such claim. The failure of the Corporation (including its Board of Directors or any committee thereof, independent legal counsel or stockholders) to make a determination concerning the permissibility of such advancement of Expenses under this Article V shall not be a defense to an action brought by a Director for recovery of the unpaid amount of an advancement claim and shall not create a presumption that such advancement is not permissible. The burden of proving that a Director is not entitled to an advancement of expenses shall be on the Corporation.

(c) In any suit brought by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the Corporation shall be entitled to recover such expenses upon a final adjudication that the Director has not met any applicable standard for indemnification set forth in the DGCL.

SECTION 6. Advancement of Expenses to Officers and Non-Officer Employees Prior to Final Disposition.

(a) The Corporation may, at the discretion of the Board of Directors, advance any or all Expenses incurred by or on behalf of any Officer or any Non-Officer Employee in connection with any Proceeding in which such person is involved by reason of his or her Corporate Status as an Officer or Non-Officer Employee upon the receipt by the Corporation of a statement or statements from such Officer or Non-Officer Employee requesting such advance or advances from time to time, whether prior to or after final disposition of such Proceeding. Such statement or statements shall reasonably evidence the Expenses incurred by such Officer or Non-Officer Employee and shall be preceded or accompanied by an undertaking by or on behalf of such person to repay any Expenses so advanced if it shall ultimately be determined that such Officer or Non-Officer Employee is not entitled to be indemnified against such Expenses.

(b) In any suit brought by the Corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the Corporation shall be entitled to recover such expenses upon a final adjudication that the Officer or Non-Officer Employee has not met any applicable standard for indemnification set forth in the DGCL.

SECTION 7. Contractual Nature of Rights.

(a) The provisions of this Article V shall be deemed to be a contract between the Corporation and each Director and Officer entitled to the benefits hereof at any time while this Article V is in effect, in consideration of such person's past or current and any future performance of services for the Corporation. Neither amendment, repeal or modification of any provision of this Article V nor the adoption of any provision of the Certificate inconsistent with this Article V shall eliminate or reduce any right conferred by this Article V in respect of any act or omission occurring, or any cause of action or claim that accrues or arises or any state of facts existing, at the time of or before such amendment, repeal, modification or adoption of an inconsistent provision (even in the case of a proceeding based on such a state of facts that is

23

commenced after such time), and all rights to indemnification and advancement of Expenses granted herein or arising out of any act or omission shall vest at the time of the act or omission in question, regardless of when or if any proceeding with respect to such act or omission is commenced. The rights to indemnification and to advancement of expenses provided by, or granted pursuant to, this Article V shall continue notwithstanding that the person has ceased to be a director or officer of the Corporation and shall inure to the benefit of the estate, heirs, executors, administrators, legatees and distributees of such person.

(b) If a claim for indemnification hereunder by a Director or Officer is not paid in full by the Corporation within sixty (60) days after receipt by the Corporation of a written claim for indemnification, such Director or Officer may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim, and if successful in whole or in part, such Director or Officer shall also be entitled to be paid the expenses of prosecuting such claim. The failure of the Corporation (including its Board of Directors or any committee thereof, independent legal counsel or stockholders) to make a determination concerning the permissibility of such indemnification under this Article V shall not be a defense to an action brought by a Director or Officer for recovery of the unpaid amount of an indemnification claim and shall not create a presumption that such indemnification is not permissible. The burden of proving that a Director or Officer is not entitled to indemnification shall be on the Corporation.

(c) In any suit brought by a Director or Officer to enforce a right to indemnification hereunder, it shall be a defense that such Director or Officer has not met any applicable standard for indemnification set forth in the DGCL.

SECTION 8. Non-Exclusivity of Rights. The rights to indemnification and to advancement of Expenses set forth in this Article V shall not be exclusive of any other right that any Director, Officer or Non-Officer Employee may have or hereafter acquire under any statute, provision of the Certificate or these Bylaws, agreement, vote of stockholders or Disinterested Directors or otherwise.

SECTION 9. Insurance. The Corporation may maintain insurance, at its expense, to protect itself and any Director, Officer or Non-Officer Employee against any liability of any character asserted against or incurred by the Corporation or any such Director, Officer or Non-Officer Employee, or arising out of any such person's Corporate Status, whether or not the Corporation would have the power to indemnify such person against such liability under the DGCL or the provisions of this Article V.

SECTION 10. Other Indemnification. The Corporation's obligation, if any, to indemnify or provide advancement of Expenses to any person under this Article V as a result of such person serving, at the request of the Corporation, as a director, partner, trustee, officer, employee or agent of another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise shall be reduced by any amount such person may collect as indemnification or advancement of Expenses from such other corporation, partnership, joint venture, trust, employee benefit plan or enterprise (the "Primary Indemnitor"). Any indemnification or advancement of Expenses under this Article V owed by the Corporation as a result of a person serving, at the request of the Corporation, as a director, partner, trustee, officer, employee or agent of another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise shall only be in excess of, and shall be secondary to, the indemnification or advancement of Expenses available from the applicable Primary Indemnitor(s) and any applicable insurance policies.

24

SECTION 11. Savings Clause. If this Article V or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the Corporation shall nevertheless indemnify each indemnitee as to any expenses (including, without limitation, attorneys' fees), liabilities, losses, judgments, fines (including, without limitation, excise taxes and penalties arising under the Employee Retirement Income Security Act of 1974, as amended) and amounts paid in settlement in connection with any action, suit, proceeding or investigation, whether civil, criminal or administrative, including, without limitation, an action by or in the right of the Corporation, to the fullest extent permitted by any applicable portion of this Article V that shall not have been invalidated and to the fullest extent permitted by applicable law.

1. Agreement to Vote. Each Class B Holder hereby agrees to vote at any meeting of the shareholders of RACC, and in any action by written resolution of the shareholders of RACC, all of such Class B Holder's RACC Class B Shares (together with any other Equity Securities of RACC that such Class B Holder holds of record or beneficially, as of the date of this Agreement, or acquires record or beneficial ownership after the date hereof, collectively, the "Subject RACC Equity Securities") in favor of the Transaction Proposals.

2. Waiver of Anti-dilution Protection.

3. Transfer of Shares.

(a) Each Class B Holder hereby agrees that he, she or it shall not, directly or indirectly, (i) sell, assign, transfer (including by operation of law), place a lien on, pledge, dispose of or otherwise encumber any of his, her or its Subject RACC Equity Securities or otherwise agree to do any of the foregoing (each, a "Transfer"), (ii) deposit any of his, her or its Subject RACC Equity Securities into a voting trust or enter into a voting agreement or arrangement or grant any proxy or power of attorney with respect to any of his, her or its Subject RACC Equity Securities that conflicts with any of the covenants or agreements set forth in this Agreement, (iii) enter into any contract, option or other arrangement or undertaking with respect to the direct or indirect acquisition or sale, assignment, transfer (including by operation of law) or other disposition of any of his, her or its Subject RACC Equity Securities, (iv) engage in any hedging or other transaction which is designed to, or which would (either alone or in connection with one or more events or developments (including the satisfaction or waiver of any conditions precedent)), lead to or result in a sale or disposition of his, her or its Subject RACC Equity Securities even if such Subject RACC Equity Securities would be disposed of by a person other than such Class B Holder or (v) take any action that would have the effect of preventing or materially delaying the performance of his, her or its obligations

1

hereunder; provided, however, that the foregoing shall not apply to any Transfer (A) to RACC's officers or directors, any affiliates or family member of any of RACC's officers or directors, any members or partners of the Sponsor or their affiliates, any affiliates of the Sponsor, or any employees of such affiliates; (B) in the case of an individual, by gift to a member of one of the individual's immediate family or to a trust, the beneficiary of which is a member of the individual's immediate family, an affiliate of such person or to a charitable organization; (C) in the case of an individual, by virtue of laws of descent and distribution upon death of the individual; (D) in the case of an individual, pursuant to a qualified domestic relations order; (E) by private sales or transfers made in connection with the transactions contemplated by the Business Combination Agreement; and (F) by virtue of the Sponsor's organizational documents upon liquidation or dissolution of the Sponsor; provided, that any transferee of any Transfer of the type set forth in clauses (A) through (F) must enter into a written agreement in form and substance reasonably satisfactory to the Company agreeing to be bound by this Agreement prior to the occurrence of such Transfer.

4. Other Covenants. Each Class B Holder hereby agrees to be bound by and subject to (i) Sections 9.2 (Confidentiality) and 9.4 (Public Announcements) of the Business Combination Agreement to the same extent as such provisions apply to the parties to the Business Combination Agreement, as if such Class B Holder is directly a party thereto, and (ii) Section 9.6 (Exclusivity) of the Business Combination Agreement to the same extent as such provisions apply to RACC as if such Class B Holder is directly party thereto.

5. Termination of RACC Class B Shares Lock-up Period.

"5. Reserved."

2

7. No Recourse. Except for claims pursuant to the Business Combination Agreement or any other Ancillary Document by any party(ies) thereto against any other party(ies) thereto, each Party agrees that (a) this Agreement may only be enforced against, and any action for breach of this Agreement may only be made against, the Parties, and no claims of any nature whatsoever (whether in tort, contract or otherwise) arising under or relating to this Agreement, the negotiation hereof or its subject matter, or the transactions contemplated hereby shall be asserted against any Company Non-Party Affiliate or any SPAC Non-Party Affiliate (other than the Class B Holders named as parties hereto, on the terms and subject to the conditions set forth herein), and (b) none of the Company Non-Party Affiliates or the SPAC Non-Party Affiliates (other than the Class B Holders named as parties hereto, on the terms and subject to the conditions set forth herein) shall have any Liability arising out of or relating to this Agreement, the negotiation hereof or its subject matter, or the transactions contemplated hereby, including with respect to any claim (whether in tort, contract or otherwise) for breach of this 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 in connection with this Agreement, the negotiation hereof or the transactions contemplated hereby.

8. Fiduciary Duties. Notwithstanding anything in this Agreement to the contrary, (a) each Class B Holder makes no agreement or understanding herein in any capacity other than in such Class B Holder's capacity as a record holder and beneficial owner of the Subject RACC Equity Securities, and not, in the case of each Other Class B Holder in such Other Class B Holder's capacity as a SPAC Related Party, and (b) nothing herein will be construed to limit or affect any action or inaction by each Other Class B Holder or any representative of the Sponsor serving as a member of the board of directors (or other similar governing body) of any SPAC Related Party or as a SPAC Related Party, in each case, acting in such person's capacity as a SPAC Related Party.

9. No Third Party Beneficiaries.

1. Events

(a) Conversion Events.

(i) In the event of a consummation of the RACC deSPAC, immediately prior to the consummation of the Share Acquisition on the Closing Date (each as defined in the Business Combination Agreement), this Safe will convert into an amount of Ordinary Shares of the Company, £0.000001 each, equal to the Purchase Amount plus accrued and unpaid Premium divided by the Safe Price. The Investor will exchange such Ordinary Shares for shares of SPAC Common Shares (as defined in the Business Combination Agreement) pursuant to the terms and conditions of the Business Combination Agreement; or

(ii) In the event the RACC deSPAC is not consummated and the Business Combination Agreement is terminated in accordance with the terms thereof, this Safe will, upon the initial closing of an Equity Financing, automatically convert into the number of shares of Safe Preferred Shares equal to the Purchase Amount plus accrued and unpaid Premium divided by the Conversion Price;

(iii) If this Safe remains outstanding eighteen (18) months following the date of execution hereof, then this Safe shall convert into shares of the Company's Series A Preferred Shares, £0.000001 each, (the "Series A Preferred Shares") in an amount equal to the Purchase Amount plus accrued and unpaid Premium divided by the original issue price of the Series A Preferred Shares (as adjusted for any share dividend, share split, combination or other similar recapitalization with respect to the Series A Preferred Shares).

In connection with the automatic conversion of this Safe into shares of Standard Preferred Shares or Safe Preferred Shares, the Investor will execute and deliver to the Company all of the transaction documents related to the Equity Financing; provided, that such documents (i) are the same documents to be entered into with the purchasers of Standard Preferred Shares, and (ii) have customary exceptions to any drag-along applicable to the Investor, including (without limitation) limited representations, warranties, liability and indemnification obligations for the Investor.

(b) Liquidity Event. If there is a Liquidity Event before the termination of this SAFE, the Investor will automatically be entitled (subject to the liquidation priority set forth in Section 1(d) below and the "MFN" Amendment Provision in Section 3 below) to receive a portion of Proceeds, due and payable to the Investor immediately prior to, or concurrent with, the consummation of such Liquidity Event, equal to the greater of (i) the Purchase Amount plus accrued and unpaid Premium (the "Cash-Out Amount") or (ii) the amount payable on the number of shares of Common Shares equal to the Purchase Amount plus accrued and unpaid Premium divided by the Liquidity Price (the "Conversion Amount"). If any of the Company's securityholders are given a choice as to the form and amount of Proceeds to be received in a Liquidity Event, the Investor will be given the same choice, provided that the Investor may not choose to receive a form of consideration that the Investor would be ineligible to receive as a result of the Investor's failure to satisfy any requirement or limitation generally applicable to the Company's securityholders, or under any applicable laws.

Notwithstanding the foregoing, in connection with a Change of Control intended to qualify as a tax-free reorganization, the Company may reduce the cash portion of Proceeds payable to the Investor by the amount determined by its board of directors in good faith for such Change of Control to qualify as a tax-free reorganization for U.S. federal income tax purposes, provided that such reduction (A) does not reduce the total Proceeds payable to such Investor and (B) is applied in the same manner and on a pro rata basis to all securityholders who have equal priority to the Investor under Section 1(d).

(c) Dissolution Event. If there is a Dissolution Event before the termination of this Safe, the Investor will automatically be entitled (subject to the liquidation priority set forth in Section 1(d) below) to receive a portion of Proceeds equal to the Cash-Out Amount, due and payable to the Investor immediately prior to the consummation of the Dissolution Event.

(d) Liquidation Priority. In a Liquidity Event (other than a deSPAC Transaction) or Dissolution Event, this Safe is intended to operate like standard non-participating Preferred Shares. The Investor's right to receive its Cash-Out Amount is:

(i) Junior to payment of outstanding indebtedness and creditor claims, including contractual claims for payment and convertible promissory notes (to the extent such convertible promissory notes are not actually or notionally converted into Capital Shares);

(ii) On par with payments for other Safes and/or Preferred Shares, and if the applicable Proceeds are insufficient to permit full payments to the Investor and such other Safes and/or Preferred Shares, the applicable Proceeds will be distributed pro rata to the Investor and such other Safes and/or Preferred Shares in proportion to the full payments that would otherwise be due; and

(iii) Senior to payments for Common Shares.

The Investor's right to receive its Cash-Out Amount is (A) on par with payments for Common Shares and other Safes and/or Preferred Shares who are also receiving Cash-Out Amounts or Proceeds on a similar as-converted to Common Shares basis, and (B) junior to payments described in clauses (i) and (ii) above (in the latter case, to the extent such payments are Cash-Out Amounts or similar liquidation preferences).

(e) Termination. This Safe will automatically terminate (without relieving the Company of any obligations arising from a prior breach of or non-compliance with this Safe) immediately following the earliest to occur of: (i) the issuance of Capital Shares to the Investor pursuant to the automatic conversion of this Safe under Section 1(a); or (ii) the payment, or setting aside for payment, of amounts due the Investor pursuant to Section 1(b) or Section 1(c); provided, however, that Section 6(h) will survive any termination of this Safe other than a termination resulting from the issuance of Capital Shares to the Investor pursuant to Section 1(a)(i), and will remain in full force and effect in accordance with its terms.

Purchaser (i) is (a) a "qualified institutional buyer" (as defined in Rule 144A under the Securities Act), (b) an institutional "accredited investor" (within the meaning of Rule 501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act) or (c) an "accredited investor" (within the meaning of Rule 501(a)(5) or (6) of Regulation D under the Securities Act), (ii) is acquiring the Backstop Purchase Shares only for its own account and not for the account of others, or if Purchaser is acquiring the Backstop Purchase Shares as a fiduciary or agent for one or more investor accounts, each owner of such account is a qualified institutional buyer, an institutional accredited investor, or an "accredited investor" (within the meaning of Rule 501(a)(5) or (6) of Regulation D under the Securities Act) and Purchaser has full investment discretion with respect to each such account, and the full power and authority to make the acknowledgements, representations and agreements herein on behalf of each owner of each such account, (iii) is not acquiring the Backstop Purchase Shares with a view to, or for offer or sale in connection with, any distribution thereof in violation of the Securities Act, and (iv) is an "institutional account" as defined by FINRA Rule 4512(c). Purchaser is not an entity formed for the specific purpose of acquiring the Backstop Purchase Shares unless such newly formed entity is an entity in which all of the equity

owners are accredited investors. Purchaser is aware that the Company is not relying specifically on the safe harbor from the registration requirements of the Securities Act provided by Regulation D under the Securities Act, and the Company will not file a Form D under the Securities Act with respect to the offer and sale of the Backstop Purchase Shares.
ii.

Purchaser acknowledges and agrees that (A) the Backstop Purchase Shares are being offered in a transaction not involving any public offering within the meaning of the Securities Act, (B) the offer and sale of the Backstop Purchase Shares have not been registered under the Securities Act and that the Company is not required to register the offer and sale of the Backstop Purchase Shares, and (C) the Backstop Purchase Shares will be "restricted securities" within the meaning of the Securities Act and may not be offered, resold, transferred, pledged or otherwise disposed of by Purchaser absent an effective registration statement under the Securities Act, except (i) to the Company or a subsidiary thereof, or (ii) pursuant to an applicable exemption from the registration requirements of the Securities Act, and, in each of cases (i) and (ii), in accordance with any applicable securities laws of the applicable states and other jurisdictions of the United States, and that any certificates or book-entry statements or instruments representing the Backstop Purchase Shares shall contain the restrictive legend set forth in Section 2(b)(ii) of this Agreement. Purchaser acknowledges and agrees that the Backstop Purchase Shares will be subject to these securities law transfer restrictions, and as a result of these transfer restrictions, Purchaser may not be able to readily resell, transfer, offer, pledge or otherwise dispose of the Backstop Purchase Shares and may be required to bear the financial risk of an investment in the Backstop Purchase Shares for an indefinite period of time. Purchaser acknowledges and agrees that the Backstop Purchase Shares will not be eligible for offer, resale, transfer, pledge or disposition pursuant to Rule 144 promulgated under the Securities Act ("Rule 144"), absent a change in law, receipt of regulatory no-action relief or an exemption, until at least one year from the Closing Date. Purchaser acknowledges and agrees that it has been advised to consult legal counsel prior to making any offer, resale, transfer, pledge or other disposition of any of the Backstop Purchase Shares.

iii.

Purchaser acknowledges that it is aware that there are substantial risks incident to the purchase and ownership of the Backstop Purchase Shares, including those set forth in the SEC Reports. Purchaser 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 Backstop Purchase Shares, and Purchaser has had an opportunity to seek, and has sought, such accounting, legal, business and tax advice as Purchaser has considered necessary to make an informed investment decision. Purchaser is an institutional account as defined in FINRA Rule 4512(c), and/or is a sophisticated investor, experienced in investing in private equity transactions and capable of evaluating investment risks independently, both in

general and with regard to all transactions and investment strategies involving a security or securities. Purchaser has determined based on its own independent review and such professional advice as it deems appropriate that its purchase of the Backstop Purchase Shares (A) are fully consistent with its financial needs, objectives and condition, (B) comply and are fully consistent with all investment policies, guidelines and other restrictions applicable to it, (C) have been duly authorized and approved by all necessary action and (D) is a fit, proper and suitable investment, notwithstanding the substantial risks inherent in investing in or holding the Backstop Purchase Shares. Purchaser understands and acknowledges that it has been informed that the purchase and sale of the Backstop Purchase Shares hereunder meets the institutional customer exemption under FINRA Rule 2111(b).
iv.

Alone, or together with any professional advisor(s), Purchaser has adequately analyzed and fully considered the risks of an investment in the Backstop Purchase Shares and determined that the Backstop Purchase Shares are a suitable investment for Purchaser and that Purchaser is able at this time and in the foreseeable future to bear the economic risk of a total loss of Purchaser's investment in the Company. Purchaser acknowledges specifically that a possibility of total loss of its investment exists.

v.

Purchaser acknowledges that Purchaser shall be responsible for any of Purchaser's tax liabilities that may arise as a result of the transactions contemplated by this Agreement, and that none of the Company, Pediatrics, or any of their respective agents or affiliates has offered Purchaser any tax advice relating to Purchaser's investment in the Backstop Purchase Shares, or made any representations, warranties or guarantees, whether written or oral, regarding the tax consequences of Purchaser's investment in the Backstop Purchase Shares.

vi.

Purchaser, together with any of its affiliates holding the Backstop Purchaser Shares or other securities of the Company, are not currently (and at all times through Closing will refrain from being or becoming) members of a "group" (within the meaning of Section 13(d)(3) or Section 14(d)(2) of the Exchange Act or any successor provision) acting for the purpose of acquiring, holding, voting or disposing of equity securities of the Company or Pediatrics (within the meaning of Rule 13d-5(b)(1) under the Exchange Act), other than a "group" consisting of Purchaser and any such affiliates and persons controlling Purchaser and any such affiliates.

vii.

Purchaser has not entered into any short sales (as defined in Rule 200 of Regulation SHO under the Exchange Act) with respect to the securities of the Company. Notwithstanding the foregoing, in the case of a Purchaser that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of Purchaser's assets and the portfolio managers have no direct

knowledge of the investment decisions made by the portfolio managers managing other portions of Purchaser'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 Backstop Purchase Shares.
d.

Financial Ability. Purchaser at the BPS Closing will have sufficient funds to pay the Subscription Amount.

e.

No Brokers. No broker or finder has acted on behalf of Subscriber in connection with the sale of the Backstop Purchase Shares pursuant to this Agreement in such way as to create any liability on the Company.

4.

i.

Modifications and Amendments. This 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, provided, that, no supplement or waiver may be made by any party hereto without the written consent of Pediatrics in case such supplement or waiver would amend Section 1, 2, 6, 7 or 8 hereof.

Construction. The parties hereto have participated jointly in the negotiation and drafting of this Agreement. If an ambiguity or question of intent or interpretation arises, this Agreement will be construed as if drafted jointly by the parties hereto and no presumption or burden of proof will arise favoring or disfavoring any party hereto because of the authorship of any provision of this Agreement. Any reference to any federal, state, local, or foreign law will be deemed also to refer to law as amended and all rules and regulations promulgated thereunder, unless the context requires otherwise. The words "include," "includes," and "including" will be deemed to be followed by "without limitation." Pronouns in masculine, feminine, and neuter genders will be construed to include any other gender, and words in the singular form will be construed to include the plural and vice versa, unless the context otherwise requires. The words "this Agreement," "herein," "hereof," "hereby," "hereunder," and words of similar import refer to this Agreement as a whole and not to any particular subdivision unless expressly so limited. The parties hereto intend that each representation, warranty, and covenant contained herein will have independent significance. If any party hereto has breached any representation, warranty, or covenant contained herein in any respect, the fact that there exists another representation, warranty or covenant relating to the same subject matter (regardless of the relative levels of specificity) which such party hereto has not breached will not detract from or mitigate the fact that such party hereto is in breach of the first representation, warranty, or covenant.

n.

Waiver. No waiver by any party hereto of any default, misrepresentation, or breach of warranty or covenant hereunder, whether intentional or not, may be deemed to extend to any prior or subsequent default, misrepresentation, or breach of warranty or covenant hereunder or affect in any way any rights arising because of any prior or subsequent occurrence.

This Agreement may be enforced only by the Company and the Purchaser, and none of the Company's direct or indirect creditors nor any other person that is not a party to this Agreement shall have any right to enforce this Agreement or to cause the Company to enforce this Agreement; provided, that, pursuant to Section 8(c), Pediatrics will have the right to specifically enforce the obligations of the Purchaser hereunder as if Pediatrics were acting on behalf of the Company.

q.

Further Assurances. Each party will, at the request of the other party, promptly take all actions, and execute and deliver all other agreements and documents, which may be reasonably required to give effect to the terms of and the transactions contemplated by this Agreement.

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.

1

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.

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.

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:

(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.

(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;

4

(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

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.

5

(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.

6

(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.

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 that in connection with the issuance and sale of the Subscribed Shares or the Pre-Funded Warrants or Pre-Funded Warrant Shares (upon exercise of Pre-Funded Warrants), no Placement Agent has acted as a financial advisor or fiduciary to any Subscriber. None of the Placement Agents or any of their respective directors, officers, employees, partners, agents, representatives or controlling persons has made any 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) or the completeness or accuracy of any information provided to the Subscriber. Subscriber acknowledges that it has not relied on the Placement Agents in connection with its determination as to the legality of its acquisition of the Subscribed Shares or the Pre-Funded Warrants or Pre-Funded Warrant Shares (upon exercise of Pre-Funded Warrants) or as to the other matters referred to herein. 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

12

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. For purposes of this Subscription Agreement, "Non-Party Affiliate" means each former, current or future officer, director, employee, partner, member, manager, direct or indirect equityholder or affiliate of the Company, OHBP, the Placement Agents or any of the Company's, OHBP's, or the Placement Agents' controlled affiliates or any family member of the foregoing. 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 and agrees that Subscriber has received or had access to, and had an adequate opportunity to review, such information as Subscriber deems necessary in order to make an investment decision with respect to the Subscribed Shares or the Pre-Funded Warrants or Pre-Funded Warrant Shares (upon exercise of Pre-Funded Warrants), including with respect to the Company and the Transactions (including OHBP and its subsidiaries (collectively, the "Acquired Companies")), and made its own assessment and is satisfied concerning the relevant financial, tax, and other economic considerations relevant to Subscriber's investment in the Subscribed Shares or the Pre-Funded Warrants or Pre-Funded Warrant Shares (upon exercise of Pre-Funded Warrants).

Without limiting the generality of the foregoing, Subscriber acknowledges that it has had an opportunity to review the Company's SEC Reports. Subscriber acknowledges and agrees that the Placement Agents and any of their respective affiliates (i) have not provided Subscriber with any information or advice with respect to the Subscribed Shares or the Pre-Funded Warrants or Pre-Funded Warrant Shares (upon exercise of Pre-Funded Warrants) nor is such information or advice necessary or desired; (ii) have not made and will not make any representation, whether express or implied, of any kind or character and have not provided any advice or recommendation in connection with the Subscription, the Transactions, the Company, the Acquired Companies, the quality or value of the Subscribed Shares, or the Pre-Funded Warrants or Pre-Funded Warrant Shares (upon exercise of Pre-Funded Warrants) any of the documents furnished pursuant therewith, or the execution, legality, validity or enforceability (with respect to any person) of any thereof, or the business, condition (financial and otherwise), management, operations, properties or prospects of, or any other matter concerning, the Company, OHBP, the Subscription or the Transactions; (iii) may have acquired non-public information with respect to the Company or the Acquired Companies which Subscriber agrees need not be provided to it; and (iv) may have existing or future business relationships with the Company and OHBP (including, but not limited to, lending, depository, risk management, advisory and banking relationships) and will pursue actions and take steps that it deems or they deem necessary or appropriate to protect its or their interests arising therefrom.

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.

(h) Subscriber acknowledges and agrees that (a) it has been informed that, in connection with the Transactions, (i) Leerink Partners LLC has acted as exclusive financial advisor to the Company and (ii) Leerink Partners LLC, UBS Securities LLC, Wells Fargo Securities, LLC and LifeSci Capital LLC have acted as co-placement agents to the Company, and (iii) any additional placement agents engaged by the Company or OHBP in connection with the Subscription may act as placement agents or advisors to the Company or OHBP after the date of this Subscription Agreement, (b) the Placement Agents are not acting as an underwriter or in any other capacity in connection with the Subscription and (c) Leerink Partners LLC will receive deferred underwriting commissions in connection with the Company's IPO (as defined below).

(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 is (i) an institutional account as defined in FINRA Rule 4512(c), and (ii) is a sophisticated investor, experienced in investing in private equity transactions and capable of evaluating investment risks independently, both in general and with regard to all transactions and investment strategies involving a security or securities.

14

(j) Alone, or together with any professional advisor(s), Subscriber has adequately analyzed and fully considered the 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 determined that the Subscribed Shares or the Pre-Funded Warrants or Pre-Funded Warrant Shares (upon exercise of Pre-Funded Warrants) are a suitable investment for Subscriber and that Subscriber is able at this time and in the foreseeable future to bear the economic risk of a total loss of Subscriber's investment in the Company. Subscriber acknowledges specifically that a possibility of total loss of its investment exists. 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).

(m) Subscriber is not, and is not owned or controlled by or acting on behalf of (in connection with this Subscription Agreement), a Sanctioned Person (as defined below). 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. Subscriber also represents that, to the extent required by applicable law, it maintains, either directly or through the use of a third-party administrator, policies and procedures reasonably designed for the screening of any investors against Prohibited Parties. Subscriber further represents and warrants that, to the extent required by applicable law, the Subscriber maintains policies and procedures reasonably designed to ensure that the funds held by Subscriber and used to purchase the Subscribed Shares or the Pre-Funded Warrants or Pre-Funded Warrant Shares (upon exercise of Pre-Funded Warrants) were legally derived. For purposes of this Subscription Agreement, "Sanctioned Person" means at any time any person or entity that is: (i) the subject or target of Sanctions, (ii) a Prohibited Party; or (iii) located, organized or resident in a country or territory that is, or whose government is, the subject or target of comprehensive Sanctions, including, as of the date of this Subscription Agreement, Crimea, the so-called Donetsk People's Republic or Luhansk People's Republic regions of Ukraine, Cuba, Iran, North Korea, and Syria.

15

(o) During the period commencing as of the time that Subscriber was first contacted by the Company, a Placement Agent or any other person regarding the transactions contemplated by this Subscription Agreement and ending immediately prior to the execution of this Subscription Agreement, Subscriber has not entered into any short sales (as defined in Rule 200 of Regulation SHO under the Exchange Act) with respect to the securities of the Company. 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.

(r) Subscriber at the Closing will have sufficient funds to pay the Purchase Price pursuant to Section 2.

(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.

16

(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.

17

(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

18

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.

19

(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.

20

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

21

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.

22

(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.

(a) At any time and from time to time in connection with a bona fide sale of Subscribed Shares, Pre-Funded Warrants (or Pre-Funded Warrant Shares issuable upon exercise of the Pre-Funded Warrants), as applicable, effected in compliance with the requirements of Rule 144 under the Securities Act or through any broker-dealer sale transactions described in the plan of distribution set forth within any prospectus and pursuant to the Registration Statement of which such prospectus forms a part, the Company shall use its commercially reasonable efforts, subject to the receipt of customary documentation required from the holder of the applicable Subscribed Shares, Pre-Funded Warrants (or Pre-Funded Warrant Shares issuable upon exercise of the Pre-Funded Warrants), as applicable, and broker, if applicable, in connection therewith and compliance with applicable laws, (i) promptly instruct its transfer agent to remove any restrictive legends applicable to the Subscribed Shares, Pre-Funded Warrants (or Pre-Funded Warrant Shares issuable upon exercise of the Pre-Funded Warrants), as applicable, being sold and (ii) cause its legal counsel to deliver the necessary legal opinions, if any, to the transfer agent in connection with the instruction under subclause (i). The Company shall be responsible for the fees of its transfer agent, its legal counsel (including for purposes of giving the opinion referenced herein) and all DTC fees associated with such issuance and legend removal and the Subscriber shall be responsible for its own fees or costs associated therewith (including its legal fees or costs of its legal counsel).

(b) With a view to making available to Subscriber the benefits of Rule 144 that permit Subscriber to sell securities of the Company to the public without registration, the Company agrees, for so long as Subscriber holds Subscribed Shares, Pre-Funded Warrants (or Pre-Funded Warrant Shares issuable upon exercise of the Pre-Funded Warrants), as applicable, to:

(i) use commercially reasonable efforts to make and keep public information available, as those terms are understood and defined in Rule 144; and

23

(ii) use commercially reasonable efforts to file with the Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act so long as the Company remains subject to such requirements and the filing of such reports and other documents as may be required pursuant to the applicable provisions of Rule 144.

(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.

10. Miscellaneous.

(a) All notices, requests, demands, claims, and other communications hereunder shall be in writing. Any notice, request, demand, claim, or other communication hereunder shall be deemed to have been duly given (i) when delivered in person, (ii) when delivered after posting in the United States mail having been sent registered or certified mail return receipt requested, postage prepaid, (iii) when delivered by FedEx or other nationally recognized overnight delivery service, or (iv) when delivered by email, during normal business hours on a Business Day and otherwise as of the opening of the immediately following Business Day, in each case, addressed to the intended recipient at its address specified on the signature page hereof or to such electronic mail address or address as subsequently modified by written notice given in accordance with this Section 10(a).

(b) Subscriber acknowledges that the Company, the Placement Agents and following the Closing Date, OHBP will rely on the acknowledgments, understandings, agreements, representations and warranties of Subscriber contained in this Subscription Agreement; provided, however, that the foregoing clause of this Section 10(b) shall not give the Company, OHBP or the Placement Agents any rights other than those expressly set forth herein. Prior to the Closing, Subscriber agrees to promptly notify the Company and the Placement Agents if it becomes aware that any of the acknowledgments, understandings, agreements, representations and warranties of Subscriber set forth herein are no longer accurate in all material respects. Subscriber acknowledges and agrees that the purchase by Subscriber of Subscribed Shares, Pre-Funded Warrants (or Pre-Funded Warrant Shares issuable upon exercise of the Pre-Funded Warrants), as applicable, from the Company will constitute a reaffirmation of the acknowledgments, understandings, agreements, representations and warranties herein (as modified by any such notice) by Subscriber as of the time of such purchase. The Company acknowledges that Subscriber and the Placement Agents will rely on the acknowledgments, understandings, agreements, representations and warranties of the Company contained in this Subscription Agreement. Prior to the Closing, the Company agrees to promptly notify Subscriber and the Placement Agents if it becomes aware that any of the acknowledgments, understandings, agreements, representations and warranties of the Company set forth herein are no longer accurate in all material respects.

(c) Each of the Company, OHBP, the Placement Agents and Subscriber is irrevocably authorized to produce this Subscription Agreement or a copy hereof to any interested party in any administrative or legal proceeding or official inquiry with respect to the matters covered hereby to the extent required by law or regulatory bodies.

24

(d) Each of the Company and Subscriber shall pay all of its own expenses in connection with this Subscription Agreement and the transactions contemplated herein.

(e) Subscriber agrees that none of the Placement Agents shall be liable to it (including in contract, tort, under federal or state securities laws or otherwise) for any action heretofore or hereafter taken or omitted to be taken by any of them in good faith in connection with the Transactions and the purchase and sale of the Subscribed Shares and Pre-Funded Warrants, as applicable, hereunder. 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.

25

(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.

26

(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.

27

(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

28

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.

FORM OF PRE-FUNDED WARRANT TO PURCHASE COMMON STOCK

Number of Shares: [•]

(subject to adjustment)

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.

REGISTRATIONS AND OFFERINGS

2.1 Shelf Registration.

2.1.1 Filing.

(a) Within thirty (30) calendar days following the Closing Date (the "Filing Deadline"), OAKH shall submit to or file with the Commission a Registration Statement for a Shelf Registration on Form S-1 (the "Form S-1 Shelf") or a Registration Statement for a Shelf Registration on Form S-3 (the "Form S-3 Shelf"), if OAKH is then eligible to use a Form S-3 Shelf, in each case, covering the resale of all the Registrable Securities (determined as of two (2) Business Days prior to such submission or filing) on a delayed or continuous basis as permitted by Rule 415 under the Securities Act (or any successor or similar provision adopted by the Commission then in effect) and shall use its commercially reasonable efforts to have such Shelf 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 OAKH 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 OAKH 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 by the Commission (such deadline the "Effectiveness Deadline"); provided, that if the Filing Deadline or Effectiveness Deadline falls on a 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 OAKH's obligations to include the Registrable Securities in the Registration Statement are contingent upon the Holder furnishing in a completed questionnaire in customary form to OAKH that contains the information required by Commission rules for a Registration Statement regarding the Holder, the securities of OAKH held by the Holder as shall be reasonably requested by OAKH to effect the registration of the Registrable Securities, and shall execute such documents in connection with such registration as OAKH may reasonably request that are customary of a selling stockholder in similar situations. If the Commission is closed for operations due to a government shutdown, the Effectiveness Deadline shall be extended by the same number of Business Days on which the Commission remains closed. Such Shelf shall provide for the resale of the Registrable Securities included therein pursuant to any method or combination of methods legally available (the "Plan of Distribution") to, and requested by, any Holder named therein. OAKH shall maintain a Shelf in accordance with the terms hereof, and shall prepare and file with the Commission such amendments, including post-effective amendments, and supplements as may be necessary to keep a Shelf continuously effective, available for use to permit the Holders named therein to sell their Registrable Securities included therein and in compliance with the provisions of the Securities Act until such time as there are no longer any Registrable Securities. In the event OAKH files a Form S-1 Shelf, OAKH shall use its commercially reasonable efforts to convert the Form S-1 Shelf (and any Subsequent Shelf Registration Statement) to a Form S-3 Shelf as soon as practicable after OAKH is eligible

6

to use Form S-3. OAKH's obligation under this Section 2.1.1, shall, for the avoidance of doubt, be subject to Section 3.4. Any failure by OAKH 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 OAKH of its obligations to file or cause the effectiveness of the Registration Statement as set forth above in this Section 2.1. Upon notification by the Commission that any Registration Statement has been declared effective by the Commission, and within two (2) Business Days thereafter, OAKH shall file the final prospectus under Rule 424 of the Securities Act.

(b) OAKH will provide a copy of such portions of the draft of the Registration Statement that include a Holder's information to such Holder 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 OAKH be required to delay or postpone the filing of such Registration Statement as a result of or in connection with a Holder's review. With respect to the Holder's information, OAKH 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 a Holder be identified as a statutory underwriter in the Registration Statement unless requested by the Commission; provided, that if the Commission requests that a Holder be identified as a statutory underwriter in the Registration Statement, such Holder will have an opportunity to withdraw from the Registration Statement, it being understood that such withdrawal shall not relieve OAKH of its obligation to register for resale the Registrable Securities at a later date.

2.1.2 Subsequent Shelf Registration. If any Shelf ceases to be effective under the Securities Act for any reason at any time while Registrable Securities are still outstanding, OAKH shall, subject to Section 3.4, use its commercially reasonable efforts to as promptly as is reasonably practicable cause such Shelf to again become effective under the Securities Act (including using its commercially reasonable efforts to obtain the prompt withdrawal of any order suspending the effectiveness of such Shelf), and shall use its commercially reasonable efforts to as promptly as is reasonably practicable amend such Shelf in a manner reasonably expected to result in the withdrawal of any order suspending the effectiveness of such Shelf or file an additional registration statement as a Shelf Registration (a "Subsequent Shelf Registration Statement") registering the resale of all Registrable Securities (determined as of two (2) Business Days prior to such filing), and pursuant to the Plan of Distribution. If a Subsequent Shelf Registration Statement is filed, OAKH shall use its commercially reasonable efforts to (i) cause such Subsequent Shelf Registration Statement to become effective under the Securities Act as promptly as is reasonably practicable after the filing thereof (it being agreed that the Subsequent Shelf Registration Statement shall be an automatic shelf registration statement (as defined in Rule 405 promulgated under the Securities Act) if OAKH is a well-known seasoned issuer (as defined in Rule 405 promulgated under the Securities Act) at the most recent applicable eligibility determination date) and (ii) keep such Subsequent Shelf Registration Statement continuously effective, available for use to permit the Holders named therein to sell their Registrable Securities included therein and in compliance with the provisions of the Securities Act until such time as there are no longer any Registrable Securities. Any such Subsequent Shelf Registration Statement shall be on Form S-3 to the extent that OAKH is eligible to use such form. Otherwise, such Subsequent Shelf Registration Statement shall be on another appropriate form. OAKH's obligation under this Section 2.1.2, shall, for the avoidance of doubt, be subject to Section 3.4.

2.1.3 Additional Registration Statement(s). Subject to Section 3.4, in the event that any Holder holds Registrable Securities that are not registered for resale on a delayed or continuous basis, OAKH, upon written request of such Holder at any time beginning 30 days prior to the expiration of the Lock-Up Period (if applicable), shall promptly use its commercially reasonable efforts to cause the resale of such Registrable Securities to be covered by filing a Subsequent Shelf Registration Statement and cause the same to become effective as soon as practicable after such filing and such Subsequent Shelf Registration Statement shall be subject to the terms hereof; provided, however, that OAKH shall only be required to cause such additional Registrable Securities to be so covered twice per calendar year for the Sponsor, RA Capital and the OAKH Existing Investors, and six times for the OHB Holders.

7

2.1.4 Requests for Underwritten Offerings. Subject to Section 3.4, at any time and from time to time and beginning 30 days prior to the expiration of the Lock-up Period (if applicable), the Sponsor, RA Capital and OAKH Existing Investors, or an OHB Holder (any such Holder being in such case, a "Demanding Holder") may request to sell all or any portion of its Registrable Securities in an Underwritten Offering that is registered pursuant to the Shelf; provided that OAKH shall only be obligated to effect an Underwritten Offering following the expiration of the Lock-Up Period (if applicable) if such offering shall include Registrable Securities proposed to be sold by the Demanding Holder, either individually or together with other Demanding Holders, with a total offering price reasonably expected to exceed, in the aggregate, $25,000,000 (the "Minimum Takedown Threshold"). All requests for Underwritten Offerings shall be made by giving written notice to OAKH, which shall specify the approximate number of Registrable Securities proposed to be sold in the Underwritten Offering. Subject to Section 2.4.4, the initial Demanding Holder shall have the right to select the Underwriters for such offering (which shall consist of one or more reputable nationally recognized investment banks), subject to OAKH's prior approval (which shall not be unreasonably withheld, conditioned or delayed). The (i) Sponsor, RA Capital and OAKH Existing Investors may demand not more than two (2) Underwritten Offerings pursuant to this Section 2.1.4 in any twelve (12) month period, and (ii) the OHB Holders, may demand not more than two (2) Underwritten Offerings pursuant to this Section 2.1.4 in any twelve (12) month period, for an aggregate of not more than six (6) Underwritten Offerings pursuant to this Section 2.1.4(i) and (ii) in any twelve (12) month period. Notwithstanding anything to the contrary in this Agreement, OAKH may effect any Underwritten Offering pursuant to any then effective Registration Statement, including a Form S-3, that is then available for such offering.

2.1.5 Reduction of Underwritten Offering. If the managing Underwriter or Underwriters in an Underwritten Offering, in good faith, advises OAKH, the Demanding Holders and the Holders requesting piggy back rights pursuant to this Agreement with respect to such Underwritten Offering (such Holders, the "Requesting Holders") (if any) in writing that the dollar amount or number of Registrable Securities that the Demanding Holders and the Requesting Holders (if any) desire to sell, taken together with all other OAKH Shares or other equity securities that OAKH desires to sell and all other OAKH Shares or other equity securities, if any, that have been requested to be sold in such Underwritten Offering pursuant to separate written contractual piggy-back registration rights held by any other stockholders, exceeds the maximum dollar amount or maximum number of equity securities that can be sold in the Underwritten Offering without adversely affecting the proposed offering price, the timing, the distribution method, or the probability of success of such offering (such maximum dollar amount or maximum number of such securities, as applicable, the "Maximum Number of Securities"), then OAKH shall include in such Underwritten Offering, before including any OAKH Shares or other equity securities proposed to be sold by OAKH or by other holders of OAKH Shares or other equity securities, (i) first, the Registrable Securities of the Demanding Holders that can be sold without exceeding the Maximum Number of Securities (pro rata based on the respective number of Registrable Securities that each Demanding Holder has requested be included in such Underwritten Offering and the aggregate number of Registrable Securities that all of the Demanding Holders have requested be included in such Underwritten Offering), (ii) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (i), the Registrable Securities of the Requesting Holders (if any) (pro rata based on the respective number of Registrable Securities that each Requesting Holder (if any) has requested be included in such Underwritten Offering and the aggregate number of Registrable Securities that all of the Requesting Holders have requested be included in such Underwritten Offering) that can be sold without exceeding the Maximum Number of Securities, (iii) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (i) and (ii), the OAKH Shares or other equity securities that OAKH desires to sell, which

8

can be sold without exceeding the Maximum Number of Securities, and (iv) fourth, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (i), (ii) and (iii), the OAKH Shares or other equity securities of persons other than Holders of Registrable Securities that OAKH is obligated to register in a Registration pursuant to separate written contractual arrangements with such persons that can be sold without exceeding the Maximum Number of Securities.

2.1.6 Withdrawal. Prior to the filing of the applicable "red herring" prospectus or prospectus supplement used for marketing such Underwritten Offering, a majority-in-interest of the Demanding Holders initiating an Underwritten Offering shall have the right to withdraw from such Underwritten Offering for any or no reason whatsoever upon written notification (a "Withdrawal Notice") to OAKH and the Underwriter or Underwriters (if any) of their intention to withdraw from such Underwritten Offering; provided that the Sponsor, RA Capital, OAKH Existing Investors, or an OHB Holder may elect to have OAKH continue an Underwritten Offering if the Minimum Takedown Threshold would still be satisfied by the Registrable Securities proposed to be sold in the Underwritten Offering by the Sponsor, RA Capital, OAKH Existing Investors, the OHB Holders or any of their respective Permitted Transferees, as applicable. If withdrawn, a demand for an Underwritten Offering shall constitute a demand for an Underwritten Offering by the withdrawing Demanding Holder for purposes of Section 2.1.4, unless such Demanding Holder reimburses OAKH for all Registration Expenses with respect to such Underwritten Offering (or, if there is more than one Demanding Holder, a pro rata portion of such Registration Expenses based on the respective number of Registrable Securities that each Demanding Holder has requested be included in such Underwritten Offering); provided that, if the Sponsor, RA Capital, OAKH Existing Investors, or an OHB Holder elects to continue an Underwritten Offering pursuant to the proviso in the immediately preceding sentence, such Underwritten Offering shall instead count as an Underwritten Offering demanded by the Sponsor, RA Capital, OAKH Existing Investors, or such OHB Holder, as applicable, for purposes of Section 2.1.4. Following the receipt of any Withdrawal Notice, OAKH shall promptly forward such Withdrawal Notice to any other Holders that had elected to participate in such Underwritten Offering. Notwithstanding anything to the contrary in this Agreement, OAKH shall be responsible for the Registration Expenses incurred in connection with an Underwritten Offering prior to its withdrawal under this Section 2.1.6, other than if a Demanding Holder elects to pay such Registration Expenses pursuant to the second sentence of this Section 2.1.6.

2.2 Piggyback Registration.

2.2.1 Piggyback Rights. Subject to Section 2.4.3, if any Holder proposes to conduct a registered offering of, or if OAKH proposes to file a Registration Statement under the Securities Act with respect to the Registration of, equity securities, or securities or other obligations exercisable or exchangeable for, or convertible into equity securities, for the account of stockholders of OAKH (or by OAKH and by the stockholders of OAKH including, without limitation, an Underwritten Offering pursuant to Section 2.1), other than a Registration Statement (or any registered offering with respect thereto) (i) filed in connection with any employee stock option or other benefit plan, (ii) pursuant to a Registration Statement on Form S-4 (or similar form that relates to a transaction subject to Rule 145 under the Securities Act or any successor rule thereto), (iii) for an offering of debt that is convertible into equity securities of OAKH, (iv) for a dividend reinvestment plan, (v) for an exchange offer or offering of securities solely to OAKH's existing securityholders, (vi) for a rights offering, (vii) for an equity line of credit or an at-the-market offering of securities, (viii) a Block Trade or (ix) an Other Coordinated Offering, then OAKH shall give written notice of such proposed offering to all of the Holders of Registrable Securities as soon as practicable but not less than five (5) days before the anticipated filing date of such Registration Statement or, in the case of an Underwritten Offering pursuant to a Shelf Registration, the applicable "red herring" prospectus or prospectus supplement used for marketing such offering, which notice shall (A) describe the amount and type of securities to be included in such offering, the intended method(s) of distribution, and the name of the proposed managing Underwriter or Underwriters, if any, in such offering, and (B) offer to all of the

Holders of Registrable Securities the opportunity to include in such registered offering such number of Registrable Securities as such Holders may request in writing within two (2) days after receipt of such written notice (such registered offering, a "Piggyback Registration"); provided, in the case of an "overnight" or "bought" offering, such requests must be made by the Holders within two (2) Business Days after delivery of any such notice by OAKH; provided further that if OAKH has been advised in writing by the managing Underwriter(s) that the inclusion of Registrable Securities for sale for the benefit of the Holders will have an adverse effect on the price, timing, or distribution of OAKH Shares in an Underwritten Offering, then (1) if no Registrable Securities can be included in the Underwritten Offering in the opinion of the managing Underwriter(s), OAKH shall not be required to offer such opportunity to such Holders or (2) if any Registrable Securities can be included in the Underwritten Offering in the opinion of the managing Underwriter(s), then the amount of Registrable Securities to be offered for the accounts of Holders shall be determined based on the provisions of Section 2.2.2. Subject to the foregoing proviso and to Section 2.2.2, OAKH shall, in good faith, cause such Registrable Securities to be included in such Piggyback Registration and, if applicable, shall use its commercially reasonable efforts to cause the managing Underwriter or Underwriters of such Piggyback Registration to permit the Registrable Securities requested by the Holders pursuant to this Section 2.2.1 to be included therein on the same terms and conditions as any similar securities of OAKH included in such registered offering and to permit the sale or other disposition of such Registrable Securities in accordance with the intended method(s) of distribution thereof. The inclusion of any Holder's Registrable Securities in a Piggyback Registration shall be subject to such Holder agreement to enter into an underwriting agreement in customary form with the Underwriter(s) selected for such Underwritten Offering.

2.2.2 Reduction of Piggyback Registration. If the managing Underwriter or Underwriters in an Underwritten Offering that is to be a Piggyback Registration, in good faith, advises OAKH and the Holders of Registrable Securities participating in the Piggyback Registration in writing that the dollar amount or number of OAKH Shares or other equity securities that OAKH desires to sell, taken together with (i) the OAKH Shares or other equity securities, if any, as to which Registration or a registered offering has been demanded pursuant to separate written contractual arrangements with persons or entities other than the Holders of Registrable Securities hereunder, (ii) the Registrable Securities as to which registration has been requested pursuant to Section 2.2 hereof, and (iii) the OAKH Shares or other equity securities, if any, as to which Registration or a registered offering has been requested pursuant to separate written contractual piggy-back registration rights of persons or entities other than the Holders of Registrable Securities hereunder, exceeds the Maximum Number of Securities, then:

(a) if the Registration or registered offering is undertaken for OAKH's account, OAKH shall include in any such Registration or registered offering (A) first, the OAKH Shares or other equity securities that OAKH desires to sell, which can be sold without exceeding the Maximum Number of Securities; (B) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (A), the Registrable Securities of Holders exercising their rights to register their Registrable Securities pursuant to Section 2.2.1, pro rata, based on the respective number of Registrable Securities that each Holder has requested be included in such Underwritten Offering and the aggregate number of Registrable Securities that the Holders have requested to be included in such Underwritten Offering, which can be sold without exceeding the Maximum Number of Securities; and (C) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), the OAKH Shares or other equity securities, if any, as to which Registration or a registered offering has been requested pursuant to separate written contractual piggy-back registration rights of persons or entities other than the Holders of Registrable Securities hereunder, which can be sold without exceeding the Maximum Number of Securities;

10

(b) if the Registration or registered offering is pursuant to a demand by persons or entities other than the Holders of Registrable Securities, then OAKH shall include in any such Registration or registered offering (A) first, the OAKH Shares or other equity securities, if any, of such requesting persons or entities, other than the Holders of Registrable Securities, which can be sold without exceeding the Maximum Number of Securities; (B) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (A), the Registrable Securities of Holders exercising their rights to register their Registrable Securities pursuant to Section 2.2.1, pro rata, based on the respective number of Registrable Securities that each Holder has requested be included in such Underwritten Offering and the aggregate number of Registrable Securities that the Holders have requested to be included in such Underwritten Offering, which can be sold without exceeding the Maximum Number of Securities; (C) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), the OAKH Shares or other equity securities that OAKH desires to sell, which can be sold without exceeding the Maximum Number of Securities; and (D) fourth, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A), (B) and (C), the OAKH Shares or other equity securities, if any, as to which Registration or a registered offering has been requested pursuant to separate written contractual piggy-back registration rights of persons or entities other than the Holders of Registrable Securities hereunder, which can be sold without exceeding the Maximum Number of Securities; and

(c) if the Registration or registered offering and Underwritten Offering is pursuant to a request by Holder(s) of Registrable Securities pursuant to Section 2.1 hereof, then OAKH shall include in any such Registration or registered offering securities in the priority set forth in Section 2.1.5.

2.2.3 Piggyback Registration Withdrawal. Any Holder of Registrable Securities (other than a Demanding Holder, whose right to withdraw from an Underwritten Offering, and related obligations, shall be governed by Section 2.1.6) shall have the right to withdraw from a Piggyback Registration for any or no reason whatsoever upon written notification to OAKH and the Underwriter or Underwriters (if any) of his, her or its intention to withdraw from such Piggyback Registration prior to the effectiveness of the Registration Statement filed with the Commission with respect to such Piggyback Registration or, in the case of a Piggyback Registration pursuant to a Shelf Registration, the filing of the applicable "red herring" prospectus or prospectus supplement with respect to such Piggyback Registration used for marketing such transaction. OAKH (whether on its own good faith determination or as the result of a request for withdrawal by persons or entities pursuant to separate written contractual obligations) may withdraw a Registration Statement filed with the Commission in connection with a Piggyback Registration (which, in no circumstance, shall include a Shelf) at any time prior to the effectiveness of such Registration Statement. Notwithstanding anything to the contrary in this Agreement (other than Section 2.1.6), OAKH shall be responsible for the Registration Expenses incurred in connection with the Piggyback Registration prior to its withdrawal under this Section 2.2.3.

2.2.4 Unlimited Piggyback Registration Rights. For purposes of clarity, subject to Section 2.1.6, any Piggyback Registration effected pursuant to Section 2.2 hereof shall not be counted as a demand for an Underwritten Offering under Section 2.1.4 hereof.

2.3 Market Stand-off. In connection with any Underwritten Offering of equity securities of OAKH (other than a Block Trade or Other Coordinated Offering) in which the Holder participates, if requested by the managing Underwriters, each such Holder that is (a) an executive officer, (b) a director or (c) Holder in excess of five percent (5%) of the outstanding OAKH Shares (and for which it is customary for such a Holder to agree to a lock-up) agrees that it shall not Transfer any OAKH Shares or other equity securities of OAKH (other than those included in such offering pursuant to this Agreement), without the prior written consent of OAKH, during the ninety (90)-day period (or such shorter time agreed to by the managing Underwriters) beginning on the date of pricing of such offering, except as expressly permitted by such lock-up agreement or in the event the managing Underwriters otherwise agree by written consent. Each such Holder agrees to execute a customary lock-up agreement in favor of the Underwriters to such effect (in each case on substantially the same terms and conditions as all such Holders).

11

2.4 Block Trades; Other Coordinated Offerings.

2.4.1 Notwithstanding any other provision of this Article II, but subject to Section 3.4, at any time and from time to time when an effective Shelf is on file with the Commission, at any time and from time to time following the expiration of the Lock-up Period (if applicable), if a Demanding Holder wishes to engage in (a) an underwritten registered offering not involving a "roadshow", an offer commonly known as a "block trade" (a "Block Trade") , or (b) an "at the market" or similar registered offering through a broker, sales agent or distribution agent, whether as agent or principal (an "Other Coordinated Offering"), in each case, (x) with a total offering price reasonably expected to exceed $20,000,000 in the aggregate or (y) with respect to all remaining Registrable Securities held by the Demanding Holder, then such Demanding Holder shall notify OAKH of the Block Trade or Other Coordinated Offering at least five (5) Business Days prior to the day such offering is to commence and OAKH shall use its commercially reasonable efforts to facilitate such Block Trade or Other Coordinated Offering; provided that the Demanding Holders representing a majority of the Registrable Securities wishing to engage in the Block Trade or Other Coordinated Offering shall use commercially reasonable efforts to work with OAKH and any Underwriters, brokers, sales agents or placement agents prior to making such request in order to facilitate preparation of the registration statement, prospectus and other offering documentation related to the Block Trade or Other Coordinated Offering.

2.4.2 Prior to the filing of the applicable "red herring" prospectus or prospectus supplement used in connection with a Block Trade or Other Coordinated Offering, a majority-in-interest of the Demanding Holders initiating such Block Trade or Other Coordinated Offering shall have the right to submit a Withdrawal Notice to OAKH, the Underwriter or Underwriters (if any) and any brokers, sales agents or placement agents (if any) of their intention to withdraw from such Block Trade or Other Coordinated Offering. Notwithstanding anything to the contrary in this Agreement, OAKH shall be responsible for the Registration Expenses incurred in connection with a Block Trade or Other Coordinated Offering prior to its withdrawal under this Section 2.4.2.

2.4.3 Notwithstanding anything to the contrary in this Agreement, Section 2.2 shall not apply to a Block Trade or Other Coordinated Offering initiated by a Demanding Holder pursuant to this Agreement.

2.4.4 The Demanding Holder in a Block Trade or Other Coordinated Offering shall have the right to select the Underwriters and any brokers, sales agents or placement agents (if any) for such Block Trade or Other Coordinated Offering (in each case, which shall consist of one or more reputable nationally recognized investment banks).

2.4.5 The (i) Sponsor, RA Capital and OAKH Existing Investors may demand no more than two (2) Block Trades or Other Coordinated Offerings pursuant to this Section 2.4 in any twelve (12) month period, and (ii) the OHB Holders, may demand no more than six (6) Block Trades or Other Coordinated Offerings pursuant to this Section 2.4 in any twelve (12) month period. For the avoidance of doubt, any Block Trade or Other Coordinated Offering effected pursuant to this Section 2.4 shall not be counted as a demand for an Underwritten Offering pursuant to Section 2.1.4 hereof.

2.5 Cutback. If the Commission prevents OAKH 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 the Holders, OAKH will promptly notify the Holders of such event, and such Registration Statement shall register for resale such number of OAKH

12

Shares which is equal to the maximum number of Registrable Securities as is permitted by the Commission. In such event, the number of OAKH Shares to be registered for the Holders shall be reduced pro rata among all such Holders (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, OAKH 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 the 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 2 shall apply with respect thereto.

ARTICLE III

OAKH PROCEDURES

3.1 General Procedures. If at any time OAKH is required to effect the Registration of Registrable Securities hereunder, OAKH shall use its commercially reasonable efforts to effect such Registration to permit the sale of such Registrable Securities in accordance with the intended plan of distribution thereof, and pursuant thereto OAKH shall:

3.1.1 prepare and file with the Commission as soon as reasonably practicable a Registration Statement with respect to such Registrable Securities and use its commercially reasonable efforts to cause such Registration Statement to become effective and remain effective until all Registrable Securities covered by such Registration Statement are sold in accordance with the intended plan of distribution set forth in such Registration Statement or have ceased to be Registrable Securities;

3.1.2 prepare and file with the Commission such amendments and post-effective amendments to the Registration Statement, and such supplements to the Prospectus, as may be reasonably requested by any Holder that holds at least five percent (5%) of the Registrable Securities registered on such Registration Statement or any Underwriter of Registrable Securities or as may be required by the rules, regulations or instructions applicable to the registration form used by OAKH or by the Securities Act or rules and regulations thereunder to keep the Registration Statement effective until all Registrable Securities covered by such Registration Statement are sold in accordance with the intended plan of distribution set forth in such Registration Statement or supplement to the Prospectus or have ceased to be Registrable Securities;

3.1.3 in connection with the filing of a Registration Statement or Prospectus, or any amendment or supplement thereto, upon the reasonable request of a Holder, furnish without charge to the Underwriters, if any, and the Holders of Registrable Securities included in such Registration, and such Holders' legal counsel, (i) excerpts of such Registration Statement naming such Holders or Underwriters, and the section entitled "Plan of Distribution", "Underwriting" or similar sections, (ii) each amendment and supplement to such Registration Statement (in each case including all exhibits thereto and documents incorporated by reference therein), (iii) the Prospectus included in such Registration Statement (including each preliminary Prospectus), and (iv) such other documents as the Underwriters and the Holders of Registrable Securities included in such Registration or the legal counsel for any such Holders may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such Holders; provided, that, in no event shall OAKH be required to delay or postpone the filing of such Registration Statement as a result of or in connection with a Holder's review; and provided, further, that OAKH shall have no obligation to furnish any documents publicly filed or furnished with the Commission pursuant to the Electronic Data Gathering, Analysis and Retrieval System ("EDGAR");

13

3.1.4 prior to any public offering of Registrable Securities, use its commercially reasonable efforts to (i) register or qualify the Registrable Securities covered by the Registration Statement under such securities or "blue sky" laws of such jurisdictions in the United States as the Holders of Registrable Securities included in such Registration Statement (in light of their intended plan of distribution) may request (or provide evidence satisfactory to such Holders that the Registrable Securities are exempt from such registration or qualification) and (ii) take such action necessary to cause such Registrable Securities covered by the Registration Statement to be registered with or approved by such other governmental authorities as may be necessary by virtue of the business and operations of OAKH and do any and all other acts and things that may be necessary or advisable to enable the Holders of Registrable Securities included in such Registration Statement to consummate the disposition of such Registrable Securities in such jurisdictions; provided, however, that OAKH shall not be required to qualify generally to do business or as a dealer in securities in any jurisdiction where it would not otherwise be required to qualify or take any action to which it would be subject to general service of process or taxation in any such jurisdiction where it is not then otherwise so subject;

3.1.5 cause all such Registrable Securities to be listed on each national securities exchange on which similar securities issued by OAKH are then listed;

3.1.6 provide a transfer agent and registrar for all such Registrable Securities no later than the effective date of such Registration Statement;

3.1.7 advise each seller of such Registrable Securities, promptly after it shall receive notice or obtain knowledge thereof, of the issuance of any stop order by the Commission suspending the effectiveness of such Registration Statement or the initiation or threatening of any proceeding for such purpose and promptly use its commercially reasonable efforts to prevent the issuance of any stop order or to obtain its withdrawal if such stop order should be issued;

3.1.8 notify the selling Holders at any time when a Prospectus relating to such Registration Statement is required to be delivered under the Securities Act, of the happening of any event as a result of which the Prospectus included in such Registration Statement, as then in effect, includes a Misstatement, and then to correct such Misstatement as set forth in Section 3.4;

3.1.9 in the event of an Underwritten Offering, a Block Trade, an Other Coordinated Offering, or sale by a broker, placement agent or sales agent pursuant to such Registration, in each of the following cases to the extent customary for a transaction of its type, permit a representative of the Holders, the Underwriters or other financial institutions facilitating such Underwritten Offering, Block Trade, Other Coordinated Offering or other sale pursuant to such Registration, if any, and any attorney, consultant or accountant retained by such Holders or Underwriter to participate, at each such person's or entity's own expense, in the preparation of the Registration Statement, and cause OAKH's officers, directors and employees to supply all information reasonably requested by any such representative, Underwriter, financial institution, attorney, consultant or accountant in connection with the Registration; provided, however, that such representatives, Underwriters or financial institutions agree to confidentiality arrangements in form and substance reasonably satisfactory to OAKH, prior to the release or disclosure of any such information;

3.1.10 obtain a "cold comfort" letter (including a bring-down letter dated as of the date the Registrable Securities are delivered for sale pursuant to such Registration) from OAKH's independent registered public accountants in the event of an Underwritten Offering or a Block Trade pursuant to such Registration (subject to such placement agent or sales agent providing such certification or representation reasonably requested by OAKH's independent registered public accountants and OAKH's counsel) in customary form and covering such matters of the type customarily covered by "cold comfort" letters for a transaction of its type as the managing Underwriter may reasonably request, and reasonably satisfactory to a majority-in-interest of the participating Holders;

14

3.1.11 in the event of an Underwritten Offering or a Block Trade pursuant to such Registration, on the date the Registrable Securities are delivered for sale pursuant to such Registration, to the extent customary for a transaction of its type, obtain an opinion and negative assurance letter, dated such date, of counsel representing OAKH for the purposes of such Registration, addressed to the participating Holders, the broker, placement agents or sales agent, if any, and the Underwriters, if any, covering such legal matters with respect to the Registration in respect of which such opinion is being given as the participating Holders, broker, placement agent, sales agent or Underwriter may reasonably request and as are customarily included in such opinions and negative assurance letters;

3.1.12 in the event of any Underwritten Offering or a Block Trade, enter into and perform its obligations under an underwriting or other purchase or sales agreement, in usual and customary form, with the managing Underwriter of such offering or sale;

3.1.13 make available to its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least twelve (12) months beginning with the first day of OAKH's first full calendar quarter after the effective date of the Registration Statement which satisfies the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder (or any successor rule then in effect), which requirement will be deemed satisfied if OAKH timely files Forms 10-K, 10-Q, and 8-K as may be required to be filed under the Exchange Act and otherwise complies with Rule 158 under the Securities Act;

3.1.14 with respect to an Underwritten Offering pursuant to Section 2.1.4, use its commercially reasonable efforts to make available senior executives of OAKH to participate in customary "road show" presentations that may be reasonably requested by the Underwriter in such Underwritten Offering; and

3.1.15 otherwise, in good faith, cooperate reasonably with, and take such customary actions as may reasonably be requested by the participating Holders, consistent with the terms of this Agreement, in connection with such Registration.

Notwithstanding the foregoing, OAKH shall not be required to provide any documents or information to an Underwriter, broker, sales agent or placement agent if such Underwriter, broker, sales agent or placement agent has not then been named with respect to the applicable Underwritten Offering or other offering involving a registration as an Underwriter, broker, sales agent or placement agent, as applicable.

3.2 Registration Expenses. The Registration Expenses of all Registrations shall be borne by OAKH. It is acknowledged by the Holders that the Holders shall bear all incremental selling expenses relating to the sale of Registrable Securities, such as Underwriters' commissions and discounts, brokerage fees, Underwriter marketing costs and, other than as set forth in the definition of "Registration Expenses," all fees and expenses of any legal counsel representing the Holders.

3.3 Requirements for Participation in Registration Statement and Underwritten Offerings. Notwithstanding anything in this Agreement to the contrary, if any Holder does not provide OAKH with its requested Holder Information, OAKH may exclude such Holder's Registrable Securities from the applicable Registration Statement or Prospectus if OAKH determines, based on the advice of counsel, that it is necessary or advisable to include such information in the applicable Registration Statement or Prospectus and such Holder continues thereafter to withhold such information. In addition, no person or entity may participate in any Underwritten Offering or other offering for equity securities of OAKH pursuant to a Registration initiated by OAKH hereunder unless such person or entity (i) agrees to sell such person's or entity's securities on the basis provided in any underwriting,

15

sales, distribution or placement arrangements approved by OAKH and (ii) completes and executes all customary questionnaires, powers of attorney, indemnities, lock-up agreements, underwriting or other agreements and other customary documents as may be reasonably required under the terms of such underwriting, sales, distribution or placement arrangements provided that such Holder shall only be subject to the restrictions set forth in any such lock-up agreements if the directors and officers of OAKH are subject to a lock-up obligation to the Underwriters managing the offering and the length of such lock-up for such Holder shall be no longer than the shortest lock-up of any such directors and officers; provided, further, that if OAKH or the Underwriters managing the offering waive or shorten the lock-up period for any of OAKH's officers, directors or stockholders, then (i) all Holders subject to such lock-up shall receive notice of such waiver or modification no later than two (2) Business Days following such waiver or modification, and (ii) such lock-up will be similarly waived pro rata or shortened for each such Holder. For the avoidance of doubt, the exclusion of a Holder's Registrable Securities as a result of this Section 3.3 shall not affect the registration of the other Registrable Securities to be included in such Registration.

3.4 Suspension of Sales; Adverse Disclosure; Restrictions on Registration Rights.

3.4.1 Upon receipt of written notice from OAKH that a Registration Statement or Prospectus contains a Misstatement, each of the Holders shall forthwith discontinue disposition of Registrable Securities until it has received copies of a supplemented or amended Prospectus correcting the Misstatement (it being understood that OAKH hereby covenants to prepare and file such supplement or amendment as soon as reasonably practicable after the time of such notice), or until it is advised in writing by OAKH that the use of the Prospectus may be resumed.

3.4.2 Subject to Section 3.4.4, if the filing, initial effectiveness or continued use of a Registration Statement in respect of any Registration at any time would (a) require OAKH to make an Adverse Disclosure, (b) require the inclusion in such Registration Statement of financial statements that are unavailable to OAKH, or (c) in the good faith judgment of the majority of the OAKH Board such Registration, be seriously detrimental to OAKH and the majority of the OAKH Board concludes as a result that it is essential to defer such filing, initial effectiveness or continued use at such time, OAKH may, upon giving prompt written notice of such action to the Holders (which notice shall not specify the nature of the event giving rise to such delay or suspension), delay the filing or initial effectiveness of, or suspend use of, such Registration Statement for the shortest period of time determined in good faith by OAKH to be necessary for such purpose. In the event OAKH exercises its rights under this Section 3.4.2, the Holders agree to suspend, immediately upon their receipt of the notice referred to above, their use of the Prospectus relating to any Registration in connection with any sale or offer to sell Registrable Securities until such Holder receives written notice from OAKH that such sales or offers of Registrable Securities may be resumed, and in each case maintain the confidentiality of such notice and its contents.

3.4.3 Subject to Section 3.4.4, (a) during the period starting with the date thirty (30) days prior to OAKH's good faith estimate of the date of the filing of, and ending on a date ninety (90) days after the effective date of, an OAKH-initiated Registration and provided that OAKH continues to actively employ, in good faith, all commercially reasonable efforts to maintain the effectiveness of the applicable Shelf Registration, or (b) if, pursuant to Section 2.1.4, Holders have requested an Underwritten Offering and OAKH and Holders are unable to obtain the commitment of underwriters to firmly underwrite such offering, OAKH may, upon giving prompt written notice of such action to the Holders, delay any other registered offering pursuant to Section 2.1.4 or 2.4.

3.4.4 The right to delay or suspend any filing, initial effectiveness or continued use of a Registration Statement pursuant to Section 3.4.2 or a registered offering pursuant to Section 3.4.3 shall be exercised by OAKH, in the aggregate, on not more than three (3) occasions or for more than ninety (90) consecutive calendar days during any twelve (12)-month period.

16

3.5 Reporting Obligations. As long as any Holder shall own Registrable Securities, OAKH, at all times while it shall be a reporting company under the Exchange Act, covenants to file timely (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by OAKH after the date hereof pursuant to Sections 13(a) or 15(d) of the Exchange Act and to promptly furnish the Holders with true and complete copies of all such filings; provided that any documents publicly filed or furnished with the Commission pursuant to EDGAR shall be deemed to have been furnished or delivered to the Holders pursuant to this Section 3.5. OAKH further covenants that it shall take such further action as any Holder may reasonably request, all to the extent required from time to time to enable such Holder to sell OAKH Shares held by such Holder without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act (or any successor rule then in effect). Upon the request of any Holder, OAKH shall deliver to such Holder a written certification of a duly authorized officer as to whether it has complied with such requirements.

3.6 Restrictive Legend Removal.

3.6.1 At any time and from time to time in connection with a bona-fide sale of Registrable Securities effected in compliance with the requirements of Rule 144 under the Securities Act or through any broker-dealer sale transactions described in the plan of distribution set forth within any prospectus and pursuant to the Registration Statement of which such prospectus forms a part, OAKH shall use its commercially reasonable efforts, subject to the receipt of customary documentation required from the holder of the applicable Registrable Securities and broker in connection therewith and compliance with applicable laws, (i) promptly instruct its transfer agent to remove any restrictive legends applicable to the Registrable Securities being sold and (ii) cause its legal counsel to deliver the necessary legal opinions, if any, to the transfer agent in connection with the instruction under subclause (i). OAKH shall be responsible for the fees of its transfer agent, its legal counsel (including for purposes of giving the opinion referenced herein) and all DTC fees associated with such issuance and the Holder shall be responsible for its fees or costs associated with such removal of such restrictive legends (including its legal fees or costs of its legal counsel).

3.6.2 With a view to making available to each Holder of Registrable Securities the benefits of Rule 144 that permit the Holder to sell securities of OAKH to the public without registration, OAKH agrees, for so long as any Holder holds Registrable Securities, to:

(a) use commercially reasonable efforts to make and keep public information available, as those terms are understood and defined in Rule 144; and

(b) use commercially reasonable efforts to file with the Commission in a timely manner all reports and other documents required of OAKH under the Securities Act and the Exchange Act so long as OAKH remains subject to such requirements and the filing of such reports and other documents as may be required pursuant to the applicable provisions of Rule 144.

ARTICLE IV

INDEMNIFICATION AND CONTRIBUTION

4.1 Indemnification.

4.1.1 OAKH agrees to indemnify, to the extent permitted by law, each Holder of Registrable Securities, its officers, directors and agents and each person or entity who controls such Holder (within the meaning of the Securities Act), against all losses, claims, damages, liabilities and out-of-pocket expenses (including, without limitation, reasonable and documented outside attorneys' fees) resulting from any untrue or alleged untrue statement of material fact contained in or incorporated by reference in any

17

Registration Statement, Prospectus 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 not misleading (in the case of a Prospectus, in light of the circumstances in which they were made), except insofar as the same are caused by or contained in any information or affidavit so furnished in writing to OAKH by such Holder expressly for use therein.

4.1.2 In connection with any Registration Statement in which a Holder of Registrable Securities is participating, such Holder shall furnish (or cause to be furnished) to OAKH in writing such information and affidavits as OAKH reasonably requests for use in connection with any such Registration Statement or Prospectus (the "Holder Information") and, to the extent permitted by law, shall indemnify OAKH, its directors, officers and agents and each person or entity who controls OAKH (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and reasonable and documented out-of-pocket expenses (including, without limitation, reasonable and documented outside attorneys' fees) resulting from any untrue or alleged untrue statement of material fact contained or incorporated by reference in any Registration Statement, Prospectus 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 not misleading (in the case of a Prospectus, in light of the circumstances in which they were made), but only to the extent that such untrue statement is contained in (or not contained in, in the case of an omission) any information or affidavit so furnished in writing by or on behalf of such Holder expressly for use therein; provided, however, that the obligation to indemnify shall be several, not joint and several, among such Holders of Registrable Securities, and the liability of each such Holder of Registrable Securities shall be in proportion to and limited to the net proceeds received by such Holder from the sale of Registrable Securities pursuant to such Registration Statement. The Holders of Registrable Securities shall indemnify the Underwriters, their officers, directors and each person or entity who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided in the foregoing with respect to indemnification of OAKH.

4.1.3 Any person or entity entitled to indemnification herein shall (i) 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 or entity's right to indemnification hereunder to the extent such failure has not materially prejudiced the indemnifying party) and (ii) 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). 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 one local counsel if necessary in the reasonable judgment of the indemnified party) for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist 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.

18

4.1.4 The indemnification provided for under this 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 or controlling person or entity of such indemnified party and shall survive the transfer of securities. OAKH and each Holder of Registrable Securities participating in an offering also agrees to make such provisions as are reasonably requested by any indemnified party for contribution to such party in the event OAKH's or such Holder's indemnification is unavailable for any reason.

4.1.5 If the indemnification provided under Section 4.1 from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and documented out-of-pocket 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, claims, damages, liabilities and documented out-of-pocket 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 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; provided, however, that the liability of any Holder under this Section 4.1.5 shall be limited to the amount of the net proceeds received by such Holder in such offering giving rise to such liability. 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 in Sections 4.1.1, 4.1.2 and 4.1.3 above, any legal or other fees, charges or out-of-pocket expenses reasonably incurred by such party in connection with any investigation or proceeding. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 4.1.5 were determined by pro rata allocation or by any other method of allocation, which does not take account of the equitable considerations referred to in this Section 4.1.5. No person or entity guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this Section 4.1.5 from any person or entity who was not guilty of such fraudulent misrepresentation.

The parties agree that all disputes, legal actions, suits and proceedings arising out of or relating to this 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 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.

20

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 AGREEMENT OR ANY PROVISION HEREOF. THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT.

5.6 Amendments and Modifications. Upon the written consent of (a) OAKH and (b) the Holders of a majority of the total Registrable Securities, compliance with any of the provisions, covenants and conditions set forth in this Agreement may be waived, or any of such provisions, covenants or conditions may be amended or modified; provided, however, that notwithstanding the foregoing, any amendment hereto or waiver hereof shall also require the written consent of (i) RA Capital so long as RA Capital and its affiliates hold, in the aggregate, Registrable Securities representing at least five percent (5%) of the outstanding OAKH Shares and (ii) an OHB Holder, for so long as such OHB Holder and its affiliates hold, in the aggregate, Registrable Securities representing at least five percent (5%) of the outstanding OAKH Shares; and provided, further, that any amendment hereto or waiver hereof that adversely affects one Holder, solely in its capacity as a holder of the shares of capital stock of OAKH, in a manner that is materially different from the other Holders (in such capacity) shall require the consent of the Holder so affected. No course of dealing between any Holder or OAKH and any other party hereto or any failure or delay on the part of a Holder or OAKH in exercising any rights or remedies under this Agreement shall operate as a waiver of any rights or remedies of any Holder or OAKH. No single or partial exercise of any rights or remedies under this Agreement by a party shall operate as a waiver or preclude the exercise of any other rights or remedies hereunder or thereunder by such party.

5.7 Other Registration Rights. Other than as provided in the (i) Private Placement Shares Purchase Agreement, dated as of June 11, 2024, between OAKH and the Sponsor and (ii) any subscription agreement entered into by OAKH and the investors party thereto in connection with a PIPE Financing, OAKH represents and warrants that no person or entity, other than a Holder of Registrable Securities, has any right to require OAKH to register any securities of OAKH for sale or to include such securities of OAKH in any Registration Statement filed by OAKH for the sale of securities for its own account or for the account of any other person or entity. OAKH hereby agrees and covenants that it will not grant rights to register any OAKH Shares (or securities convertible into or exchangeable for OAKH Shares) pursuant to the Securities Act that are more favorable than those granted to the Holders hereunder without (a) the prior written consent of (i) RA Capital so long as RA Capital and its affiliates hold, in the aggregate, Registrable Securities representing at least five percent (5%) of the outstanding OAKH Shares and (ii) an OHB Holder, for so long as such OHB Holder and its affiliates hold, in the aggregate, Registrable Securities representing at least five percent (5%) of the outstanding OAKH Shares or (b) granting substantially equivalent rights to the Holders hereunder such that the Holders shall receive the benefit of such more favorable or senior terms and/or conditions. Further, OAKH represents and warrants that this Agreement supersedes any other registration rights agreement or agreement with similar terms and conditions and in the event of a conflict between any such agreement or agreements and this Agreement, the terms of this Agreement shall prevail. Notwithstanding the foregoing, nothing in this Section 5.7 shall prohibit the Company from filing a registration statement for one or more bona fide underwritten public offerings (including on Form S-1) where the Board determines in good faith that such offering is reasonably necessary to facilitate the disposition of securities by one or more holders whose securities are not then eligible for resale pursuant to an effective Registration Statement.

21

5.8 Term. This Agreement shall terminate on the earlier of (a) the fifth (5th) anniversary of the date of this Agreement and (b) with respect to any Holder, on the date that such Holder no longer holds any Registrable Securities. The provisions of Sections 3.5 and Article IV shall survive any termination.

5.9 Holder Information. Each Holder agrees, if requested in writing, to represent to OAKH the total number of Registrable Securities held by such Holder in order for OAKH to make determinations hereunder.

5.10 Severability. It is the desire and intent of the parties that the provisions of this Agreement be enforced to the fullest extent permissible under the laws and public policies applied in each jurisdiction in which enforcement is sought. Accordingly, if any particular provision of this Agreement shall be adjudicated by a court of competent jurisdiction to be invalid, prohibited or unenforceable for any reason, such provision, as to such jurisdiction, shall be ineffective, without invalidating the remaining provisions of this Agreement or affecting the validity or enforceability of this Agreement or affecting the validity or enforceability of such provision in any other jurisdiction. Notwithstanding the foregoing, if such provision could be more narrowly drawn so as not to be invalid, prohibited or unenforceable in such jurisdiction, it shall, as to such jurisdiction, be so narrowly drawn, without invalidating the remaining provisions of this Agreement or affecting the validity or enforceability of such provision in any other jurisdiction.

5.11 Entire Agreement; Restatement. This Agreement constitutes the full and entire agreement and understanding between the parties with respect to the subject matter hereof and supersedes all prior agreements and understandings relating to such subject matter. Upon the Closing, the Original RSRA shall no longer be of any force or effect.

5.12 Adjustments. If, and as often as, there are any changes in the Registrable Securities by way of stock split, stock dividend, combination or reclassification, or through merger, consolidation, reorganization, recapitalization or sale, or by any other means, appropriate adjustment shall be made in the provisions of this Agreement, as may be required, so that the rights, privileges, duties and obligations hereunder shall continue with respect to the Registrable Securities as so changed.

A COPY OF SUCH LOCK-UP AGREEMENT WILL BE FURNISHED WITHOUT CHARGE BY THE ISSUER TO THE HOLDER HEREOF UPON WRITTEN REQUEST."

6. PubCo represents that it has not entered into any side letter or agreement with any Holder which provides any rights or benefits to such Holder that are materially more favorable to such Holder than the rights and benefits in this Agreement and will not enter into any such side letter or agreement unless such rights and benefits are also offered to the other Holders.

Exhibit 99.1

Oak Hill Bio and Research Alliance Corporation III Announce Business Combination Agreement to Create Publicly Listed Rare Disease Biotechnology Company to Advance Antisense Oligonucleotide Therapy Rugonersen for Angelman Syndrome

Transaction to provide Oak Hill Bio with approximately $175 million in gross proceeds, including $75 million of cash in Research Alliance Corporation III's (Nasdaq: RACC) ("RACC") trust account that is fully backstopped by RA Capital Management and a $100 million committed private financing.

Together with Oak Hill Bio's recent $32.5 million Series A financing, the transaction is expected to provide cash runway for development of rugonersen, a potential best-in-class antisense oligonucleotide (ASO) for the treatment of Angelman syndrome, through Phase 3 readout and potential new drug application (NDA) submission in 2H2029.

Current RACC Director and former Avidity Biosciences CFO Mike MacLean to remain on the Board of the combined company post-closing.

Business combination expected to close by year-end 2026, and the combined company expected to trade on the Nasdaq Capital Market under the ticker symbol "OAKH".

Cambridge and New York (United States), July 27, 2026 - OHB Pediatrics Ltd. d/b/a Oak Hill Bio, a clinical-stage rare disease therapeutics company, and RACC, a special purpose acquisition company (SPAC) sponsored by RA Capital Management, today announced that they have entered into a definitive business combination agreement. In connection with consummation of the transaction, which is expected to close by year-end 2026 subject to customary closing conditions, RACC would redomesticate as a Delaware corporation and be renamed Oak Hill Bio, Inc., and its shares of common stock would be listed on the Nasdaq Capital Market under the ticker symbol "OAKH".

Oak Hill Bio is developing rugonersen, an investigational ASO therapy for the treatment of Angelman syndrome, in the pivotal Phase 3 BEACON clinical trial (NCT07605429) which dosed its first patient in July 2026. Angelman syndrome is a devastating neurodevelopmental disorder affecting approximately 30,000 diagnosed patients in the U.S. and European Group of Five countries ("EU5") with no approved disease-modifying therapies. Rugonersen was originally developed by Roche as a highly potent and specific therapy to restore neuronal UBE3A expression, acting as a potential disease modifying treatment, and was licensed by Oak Hill Bio from Roche in February 2025. Several former members of the rugonersen program have joined Oak Hill Bio to lead further development.

"We are excited to announce a business combination with Research Alliance Capital III and partnering with RA Capital," said Josh Distler, Chief Executive Officer of Oak Hill Bio. "The resources provided by this amazing group of investors will enable us to continue to aggressively develop rugonersen. We have dosed the first patient in the Phase 3 BEACON trial and look forward to evaluating the potential of rugonersen to meaningfully impact the lives of patients living with Angelman syndrome and their families."

"Oak Hill Bio combines compelling science, a management team with a broad range of experience, and an extremely promising rare disease asset, making for a solid foundation for continued success," said Matthew Hammond, Partner at RA Capital and CEO and Director of RACC. "We are excited to lead this transaction and support Oak Hill Bio as the team brings rugonersen into pivotal development and towards a potential registration for a best-in-class treatment for Angelman syndrome."

Summary of the Transaction

The proposed transaction is expected to provide Oak Hill Bio with approximately $175 million in gross proceeds before transaction expenses, including $75 million of cash in RACC's trust account that is fully backstopped by RA Capital and a $100 million committed private financing.

About Oak Hill Bio

Oak Hill Bio is a clinical-stage biotechnology company focused on acquiring and developing promising therapeutics for rare diseases with significant unmet need that have been deprioritized by pharmaceutical companies. The company's lead program is rugonersen (OHB-724), an investigational antisense oligonucleotide (ASO) in Phase 3 clinical development as a potential best-in-class treatment for Angelman syndrome, a devastating neurodevelopmental disorder with no approved disease-modifying therapies.

Oak Hill Bio is the trading name for OHB Pediatrics Ltd. It was formed in 2024 as a subsidiary of Oak Hill Bio Holdings (formerly known as Oak Hill Bio Ltd).

About Angelman Syndrome

Angelman syndrome (AS) is a serious rare genetic neurodevelopmental disorder that causes severe mental and physical impairment and affects approximately 15,000 patients in each of the U.S. and the EU5, with an estimated incidence of 1 in 12,000 to 20,000 live births. AS is characterized by global developmental delay, intellectual disability, epilepsy (90% of cases before age 3 years) with an atypical underlying electroencephalogram (EEG), ataxia, tremor, hyperactivity, limited speech, and sleep dysregulation. Symptoms often emerge during infancy and persist throughout life. Deletions and mutations in the maternal ubiquitin protein ligase E3A (UBE3A) allele cause Angelman syndrome, due to epigenetic silencing of the paternal UBE3A allele by a long non-coding antisense RNA (UBE3A-ATS) in neurons. UBE3A is required for normal brain development and function. Failure to express UBE3A in central nervous system (CNS) neurons leads to a build-up of damaged or unwanted proteins, that if left unchecked, can paralyze normal neuronal maturation, function, and synaptic pruning.

About Rugonersen

Rugonersen is an antisense oligonucleotide (ASO) designed to address the underlying disease biology of Angelman syndrome (AS) by specifically and potently binding the UBE3A-ATS transcript. Rugonersen binding is intended to trigger degradation of the UBE3A-ATS transcript in the CNS and therefore the unsilencing of the UBE3A paternal allele. Rugonersen allows neuronal expression of the paternal wild-type copy of the UBE3A gene, potentially improving neuronal function and development in AS patients.

Rugonersen's clinical and preclinical data are detailed in the following publications: Hipp, J.F., Bacino, C.A., Bird, L.M. et al. The UBE3A-ATS antisense oligonucleotide rugonersen in children with Angelman syndrome: a Phase 1 trial. Nat Med (2025). https://doi.org/10.1038/s41591-025-03784-7 ; Jagasia et al., Angelman syndrome patient-derived neuron screen leads to clinical ASO rugonersen targeting UBE3A-ATS with long-lasting effect in monkeys, Nucleic Acids Research (2025). https://doi.org/10.1093/nar/gkaf851

CORPORATE Risk Factors (1 of 7) Certain factors may have a material adverse effect on our business, financial condition and results of operations. The risks and uncertainties described below are not the only ones we and the post-business combination public company will face. Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, may also become important factors that adversely affect our business. If any of the following risks actually occur, our business, financial condition, results of operations and future prospects could be adversely affected. In that event, you could lose all or part of your investment. All references in this section to "we", "our" or "us" refer both to the business of OHB Pediatrics Ltd ("Oak Hill Bio") prior to the consummation of the proposed business combination and to the business of the post-business combination public company and its subsidiaries, as applicable. The list below has been prepared solely for the purpose of the private placement transaction, and solely for potential private placement investors, and not for any other purpose. Accordingly, the list below is qualified in its entirety by disclosures contained in future documents filed or furnished by Oak Hill Bio and Research Alliance Corporation III ("RAC III") or otherwise with respect to Oak Hill Bio and RAC III, with the Securities and Exchange Commission (the "SEC"), including the documents filed or furnished in connection with the proposed transactions between Oak Hill Bio and RAC III. The risks presented in such filings may differ significantly from and be more extensive than those presented below. Risks Related to Oak Hill Bio's Financial Position and Need for Additional Capital • Oak Hill Bio is substantially dependent on the success of rugonersen, its current sole product candidate. If Oak Hill Bio is unable to complete development of, obtain approval for and commercialize rugonersen or any future product candidate it may develop in a timely manner or at all, its business will be harmed. • Oak Hill Bio has incurred significant losses since inception, has no products approved for sale, only has one product candidate and expects to incur losses for the foreseeable future. • To become and remain profitable, Oak Hill Bio must succeed in identifying, acquiring, developing, and obtaining the necessary regulatory approvals for products or product candidates that generate significant revenue, either through commercialization or out licensing. • Oak Hill Bio will need substantial additional funding to advance its current and future product candidates, including rugonersen. If Oak Hill Bio is unable to obtain substantial additional funding when needed, it could be forced to delay, scale back or discontinue its product development programs or future commercialization efforts. • Oak Hill Bio's limited operating history may make it difficult for you to evaluate the success of Oak Hill Bio's business to date and to assess Oak Hill Bio's future viability. Risks Related to Oak Hill Bio's Discovery, Development, Preclinical and Clinical Testing • If Oak Hill Bio is unable to advance rugonersen or any other product candidates through preclinical studies and clinical trials, obtain marketing approval and ultimately commercialize them, or experiences significant delays in doing so, Oak Hill Bio's business will be materially harmed. • Oak Hill Bio's ability to complete clinical trials may be adversely impacted if it experiences delays or difficulties in the enrollment of patients in clinical trials. • Oak Hill Bio may not be successful in its efforts to identify, discover or develop potential product candidates. • Drug development is a lengthy and expensive process, and preclinical and clinical testing is uncertain as to the outcome. Oak Hill Bio may encounter substantial delays in the commencement, enrollment or completion of its clinical trials and may never advance to clinical trials, or it may fail to demonstrate safety and effectiveness to the satisfaction of applicable regulatory authorities, which could prevent it from advancing or commercializing its product candidates on a timely basis, if at all. • The outcome of preclinical studies and earlier-stage clinical trials may not be predictive of future results or the success of later preclinical studies and clinical trials. • Interim, initial, "topline" and preliminary data from Oak Hill Bio's preclinical studies or clinical trials that Oak Hill Bio announces or publishes from time to time may change as more patient data become available and are subject to audit and verification procedures that could result in material changes in the final data. • If rugonersen or any of Oak Hill Bio's future product candidates cause undesirable side effects or have other unexpected adverse properties, such side effects or properties could delay or prevent the initiation or completion of clinical trials, preclude or delay regulatory approval, limit the commercial potential of such candidate or result in significant negative consequences following any potential marketing approval. • Oak Hill Bio may expend its limited resources to pursue a particular program, product candidate or indication and fail to capitalize on programs, product candidates or indications that may be more profitable or for which there is a greater likelihood of success. • The increasing use of social media platforms presents new risks and challenges. • Clinical trial and product liability lawsuits against Oak Hill Bio could divert Oak Hill Bio's resources, cause Oak Hill Bio to incur substantial liabilities and limit commercialization of Oak Hill Bio's product candidates. • Oak Hill Bio may conduct certain clinical trials for its product candidates outside of the United States. However, the FDA and comparable foreign regulatory authorities may not accept data from such trials, in which case Oak Hill Bio's development plans will be delayed, which could materially harm Oak Hill Bio's business. Private and Confidential - Not to be Retained Oak Hill Bio 20

CORPORATE Risk Factors (2 of 7) Risks Related to Oak Hill Bio's Dependence on Third Parties • Oak Hill Bio relies, and expects to continue to rely, on third parties to conduct some or all aspects of Oak Hill Bio's product manufacturing, research and preclinical and clinical testing, and these third parties may not perform satisfactorily. If Oak Hill Bio needs to replace one or more of these third parties, its development plans may be significantly delayed and it may expend more funds than currently planned. • Oak Hill Bio currently depends on a small number of third-party suppliers to supply the product candidates that it is evaluating in its research and development programs. The loss of these or future third-party suppliers, or their inability to provide Oak Hill Bio with sufficient supply, could harm Oak Hill Bio's business. • Oak Hill Bio is dependent on single-source suppliers for some of the components and materials used in its product candidates. • Oak Hill Bio currently intends to commercialize rugonersen independently, if approved, although it may seek to establish collaborations with third parties for commercialization in certain geographies or indications. Oak Hill Bio has no experience as a company in commercializing products, and there can be no assurance that it will be able to do so successfully. • Oak Hill Bio may enter into collaborations with third parties for the research, development and commercialization of certain of its product candidates. If any such collaborations are not successful, Oak Hill Bio may not be able to capitalize on the market potential of those product candidates. • If conflicts arise between Oak Hill Bio and its potential collaborators, these parties may act in a manner adverse to Oak Hill Bio and could limit its ability to implement its strategies. • Oak Hill Bio is dependent on third-party vendors to provide certain licenses, products and services, and its business and operations, including clinical trials, could be disrupted by any problems with its significant third-party vendors. Risks Related to Oak Hill Bio's Regulatory Approval and Other Regulatory and Legal Compliance Matters • Oak Hill Bio has not yet completed any clinical trials and may be unable to do so for rugonersen or any future product candidates. • Even if Oak Hill Bio completes the necessary preclinical studies and clinical trials, the marketing approval process is expensive, time-consuming and uncertain and may prevent Oak Hill Bio from obtaining approvals for the commercialization of its product candidates. If Oak Hill Bio is not able to obtain, or if there are delays in obtaining, required regulatory approvals, Oak Hill Bio will not be able to commercialize, or will be delayed in commercializing, its product candidates, and its ability to generate revenue will be materially impaired. • Obtaining and maintaining marketing approval or commercialization of Oak Hill Bio's product candidates in the United States does not mean that Oak Hill Bio will be successful in obtaining marketing approval of its product candidates in other jurisdictions. Failure to obtain marketing approval in foreign jurisdictions would prevent Oak Hill Bio's product candidates from being marketed in such jurisdictions, which, in turn, would materially impair Oak Hill Bio's ability to generate revenue. • Oak Hill Bio may seek one or more designations or expedited programs for one or more of its product candidates, but it might not receive such designations or be allowed to proceed on expedited program pathways, and even if it does and proceeds on such expedited program pathways in the future, such designations or expedited programs may not lead to a faster development or regulatory review or approval process, and each designation does not increase the likelihood that any of Oak Hill Bio's product candidates will receive marketing approval in the United States. • Oak Hill Bio has obtained orphan drug designation for rugonersen and may pursue a similar strategy for future product candidates, and it may not be able to obtain such designation or obtain or maintain the benefits of such designation including orphan drug exclusivity, and even if it does, that exclusivity may not prevent regulatory authorities from approving other competing products. • A marketing application for a product candidate with rare pediatric disease designation, or RPDD, if approved, may not meet the eligibility criteria for a Priority Review Voucher, or PRV, or the RPDD program may sunset before the FDA is able to consider eligibility for a voucher. • Oak Hill Bio may also in the future seek approval from the FDA or comparable foreign regulatory authorities for its current or future product candidates, where applicable, under the accelerated approval pathways. Oak Hill Bio may fail to obtain approval under such accelerated approval pathways. Moreover, these pathways may not lead to a faster development, regulatory review or approval process and do not increase the likelihood that Oak Hill Bio's product candidates will receive marketing approval. • Even if Oak Hill Bio receives regulatory approval for any of its product candidates, it will be subject to ongoing regulatory obligations and continued regulatory review, which may result in significant additional expense. Additionally, Oak Hill Bio's product candidates, if approved, could be subject to post-market study requirements, marketing and labeling restrictions, and even recall or market withdrawal if unanticipated safety issues are discovered following approval. In addition, Oak Hill Bio may be subject to penalties or other enforcement action if Oak Hill Bio fails to comply with regulatory requirements. • Any product candidate for which Oak Hill Bio obtains marketing approval will be subject to restrictions, such as the laws and regulations prohibiting the promotion of off-label uses, or may need to be withdrawn from the market, and Oak Hill Bio may be subject to substantial penalties if it fails to comply with regulatory requirements or if it experiences unanticipated problems with its medicines, when and if any of them are approved. • Oak Hill Bio and its contract manufacturers are subject to significant regulation. The manufacturing facilities on which Oak Hill Bio rely may not continue to meet regulatory requirements, which could materially harm Oak Hill Bio's business.

CORPORATE Risk Factors (3 of 7) Risks Related to Oak Hill Bio's Regulatory Approval and Other Regulatory and Legal Compliance Matters (cont.) • If Oak Hill Bio or any contract manufacturers and suppliers Oak Hill Bio engages fail to comply with environmental, health, and safety laws and regulations, Oak Hill Bio could become subject to fines or penalties or incur significant costs. • Shutdowns or disruptions at the FDA and other government agencies caused by funding shortages or global health concerns could hinder their ability to hire, retain or deploy key leadership and other personnel, or otherwise prevent new or modified products from being developed, approved or commercialized in a timely manner or at all, which could negatively impact Oak Hill Bio's business. • Oak Hill Bio's relationships with healthcare providers, physicians and third-party payors will be subject to applicable anti-kickback, fraud and abuse, and other healthcare laws and regulations, which could expose Oak Hill Bio to criminal sanctions, civil penalties, contractual damages, reputational harm and diminished profits and future earnings. • Healthcare legislative reform discourse and potential or enacted measures may increase the difficulty and cost for Oak Hill Bio and any future collaborators to obtain marketing approval of and commercialize its product candidates and affect the prices it or they may obtain. • Oak Hill Bio's service providers, principal investigators, consultants and commercial partners may engage in misconduct or other improper activities, including non-compliance with regulatory standards and requirements and insider trading. • Laws and regulations governing any international operations Oak Hill Bio may have in the future may preclude it from developing, manufacturing and selling certain product candidates outside of the United States and require it to develop and implement costly compliance programs. • Oak Hill Bio is subject to stringent data protection, privacy, and security laws, regulations, standards and contractual obligations and actual or perceived failure to comply with such requirements could have a material adverse effect on Oak Hill Bio's business, financial condition, results of operations or prospects. • Oak Hill Bio's use of new and evolving technologies, such as artificial intelligence, may present risks and challenges that can impact its business, including by posing cybersecurity and other risks to its confidential and/or proprietary information, including personal information, and as a result Oak Hill Bio may be exposed to reputational harm and liability. • If any of Oak Hill Bio's product candidates obtains regulatory approval and does not receive appropriate periods of non-patent exclusivity, competitors could enter the market with generic versions of such products more quickly than Oak Hill Bio expects, which may result in a material decline in sales of Oak Hill Bio's products. Risks Related to Oak Hill Bio's Commercialization • Oak Hill Bio faces substantial competition, which may result in others discovering, developing or commercializing products before, or more successfully than, Oak Hill Bio. • Even if one or more of Oak Hill Bio's product candidates receives marketing approval, it may fail to achieve the degree of market acceptance by physicians, patients, third-party payors and others in the medical community necessary for commercial success. • If the market opportunities for any product candidates Oak Hill Bio develops are smaller than Oak Hill Bio believes they are, Oak Hill Bio's revenue may be adversely affected and its business may suffer. Because the target patient populations of Oak Hill Bio's programs are small, and the addressable patient population even smaller, Oak Hill Bio must be able to successfully identify patients and capture a significant market share to achieve profitability and growth. • The estimates of market opportunity and forecasts of market growth included in this investor presentation, if any, may prove to be inaccurate, and even if the markets in which Oak Hill Bio competes achieve the forecasted growth, Oak Hill Bio's business may not grow at similar rates, or at all. • The pricing and third-party payor coverage and reimbursement status of newly approved products are uncertain. Failure to obtain or maintain adequate coverage and reimbursement for Oak Hill Bio's future product candidates, if approved, could limit Oak Hill Bio's ability to market those products and decrease its ability to generate product revenue. • If Oak Hill Bio is unable to establish sales, marketing and distribution capabilities or enter into sales, marketing and distribution agreements with third parties, Oak Hill Bio may not be successful in commercializing its product candidates if any are approved. Risks Related to Oak Hill Bio's Intellectual Property • If Oak Hill Bio is unable to obtain and maintain patent protection for its therapeutic programs and other proprietary technologies it develops, or if the scope of the patent protection obtained is not sufficiently broad, its competitors could develop and commercialize products and technology similar or identical to Oak Hill Bio's, and its ability to successfully commercialize its therapeutic programs and other proprietary technologies it may develop may be adversely affected. • Oak Hill Bio may not be able to protect its intellectual property and proprietary rights throughout the world. • Obtaining and maintaining patent protection depends on compliance with various procedural, document submission, fee payment, and other requirements imposed by government patent agencies, and Oak Hill Bio's patent protection could be reduced or eliminated for non-compliance with these requirements. Private and Confidential - Not to be Retained Oak Hill Bio 22

CORPORATE Risk Factors (4 of 7) Risks Related to Oak Hill Bio's Intellectual Property (cont.) • Changes in U.S. patent law could diminish the value of patents in general, thereby impairing Oak Hill Bio's ability to protect its products. • Issued patents covering Oak Hill Bio's therapeutic programs and other proprietary technologies it may develop could be found invalid or unenforceable if challenged in court or before administrative bodies in the United States or abroad. • Oak Hill Bio may be subject to claims challenging the inventorship of its patents and other intellectual property. • If Oak Hill Bio is unable to protect the confidentiality of its trade secrets, its business and competitive position would be harmed. • Oak Hill Bio may be subject to claims that its service providers, consultants or advisors have wrongfully used or disclosed alleged trade secrets of their current or former employers or claims asserting ownership of what it regards as its own intellectual property. • Third-party claims of intellectual property infringement, misappropriation or other violations against Oak Hill Bio or its collaborators may prevent or delay the development and commercialization of its therapeutic programs and other proprietary technologies it may develop. • Oak Hill Bio may become involved in lawsuits to protect or enforce its patents and other intellectual property rights, which could be expensive, time consuming and unsuccessful. • If Oak Hill Bio's trademarks and trade names are not adequately protected, then it may not be able to build name recognition in its markets of interest and its business may be adversely affected. • Intellectual property rights do not necessarily address all potential threats. • Intellectual property discovered through government funded programs may be subject to federal regulations such as "march-in" rights, certain reporting requirements and a preference for U.S.-based companies. Compliance with such regulations may limit Oak Hill Bio's exclusive rights and limit its ability to contract with non-U.S. manufacturers. • Oak Hill Bio partially depends on intellectual property licensed from third parties, and its licensors may not always act in its best interest. If Oak Hill Bio fails to comply with its obligations under its intellectual property licenses, if the licenses are terminated or if disputes regarding these licenses arise, it could lose significant rights that are important to its business. • Oak Hill Bio may not be successful in obtaining or maintaining necessary rights to product components and processes for its development pipeline through acquisitions (including in-licenses). • Oak Hill Bio's use of open source software could impose limitations on its ability to commercialize its product candidates. Risks Related to Oak Hill Bio's Personnel Matters, Managing Growth and Other Operational Matters • Oak Hill Bio's future success depends on Oak Hill Bio's ability to retain key executives and to attract, retain and motivate qualified personnel. • Oak Hill Bio will need to expand its headcount over time to support its development and regulatory capabilities and potentially implement sales, marketing and distribution capabilities, and as a result, it may encounter difficulties in managing its growth, which could disrupt its operations. • Oak Hill Bio's international activities subject it to various risks, and its failure to manage these risks could adversely affect its results of operations. • Oak Hill Bio faces risks associated with tariffs and other trade restrictions, which may have a material adverse impact on its results of operations and financial condition. • Future acquisitions or strategic alliances could disrupt Oak Hill Bio's business and harm its financial condition and results of operations. • Oak Hill Bio's internal information technology systems, or those of its vendors, collaborators or other contractors or consultants, may fail or suffer from cybersecurity incidents or breaches, loss or leakage of data and other disruptions or compromise, which could result in a material disruption of its product development programs, compromise sensitive information related to its business or prevent it from accessing critical information, or trigger contractual and legal obligations, potentially exposing Oak Hill Bio to liability or reputational harm or otherwise adversely affecting its business and financial results. • Oak Hill Bio's operations or those of the third parties upon whom it depends might be affected by the occurrence of a natural disaster, pandemic or other catastrophic event. • Adverse developments affecting the financial services industry, such as actual events or concerns involving liquidity, defaults, or non-performance by financial institutions or transactional counterparties, could adversely affect Oak Hill Bio's current and projected business operations and its financial condition and results of operations. • The effects of a future pandemic, epidemic or outbreak of an infectious or highly contagious disease may materially and adversely affect Oak Hill Bio's business and financial results and could cause a disruption in the development of its product candidates.

CORPORATE Risk Factors (5 of 7) General Oak Hill Bio Risk Factors • Changes in tax laws or regulations or in their implementation or interpretation may adversely affect Oak Hill Bio's business and financial condition. • Tax authorities may disagree with Oak Hill Bio's positions and conclusions regarding certain tax positions, or may apply existing rules in an unforeseen manner, resulting in unanticipated costs, taxes or non-realization of expected benefits. • Oak Hill Bio's ability to utilize its net operating loss carryforwards and certain other tax attributes may be subject to limitations. • Oak Hill Bio's disclosure controls and procedures may not prevent or detect all errors or acts of fraud. • As a public company, Oak Hill Bio will be exposed to the risk of securities class action litigation. • Oak Hill Bio may be exposed to significant foreign exchange risk. Risks Related to the Business Combination • The consummation of the Business Combination is subject to a number of conditions, and if those conditions are not satisfied or waived, the Business Combination may not be completed. • Some of RAC III's, Oak Hill Bio's or the post-closing combined company's officers and directors may have conflicts of interest that may influence them to approve the proposed Business Combination without regard to your interests. • RAC III's directors and officers may have interests in the proposed Business Combination different from the interests of RAC III, Oak Hill Bio, and/or the post-closing combined company. • There can be no assurance that Oak Hill Bio and RAC III will be able to raise sufficient capital through the proposed financing transactions, including the PIPE Investment, the interim financing provided by the Sponsor to Oak Hill Bio in the form of a SAFE (the "RAC Interim Financing") and any related backstop arrangements, to consummate the proposed Business Combination. • The consummation of the proposed PIPE Investment is conditioned on the closing of the proposed Business Combination, and the closing of the proposed Business Combination will be subject to a number of closing conditions, some of which will be outside of Oak Hill Bio and RAC III's control, including approval by the shareholders of RAC III. • The RAC Interim Financing is conditioned on and integral to the consummation of the proposed Business Combination, and any failure to complete, or delay in completing, the proposed Business Combination could adversely affect the terms on which the RAC Interim Financing converts and result in dilution to holders of securities of the post-closing combined company. If the proposed Business Combination is not consummated, the SAFE issued in the RAC Interim Financing may convert into equity of Oak Hill Bio pursuant to its terms, which could delay or otherwise deter any alternative transaction relating to Oak Hill Bio. There can be no assurance that the RAC Interim Financing will remain available on its current terms or that its existence will not create additional risks to or otherwise delay of the closing of the proposed Business Combination. • A portion of the total outstanding shares of the post-closing combined company is expected to be restricted from immediate resale but may be sold into the market in the near future. • Sales of a substantial number of shares of the post-closing combined company's common stock in the public market by existing shareholders could cause the post-closing combined company's share price to decline, even if Oak Hill Bio's business is doing well. • RAC III's shareholders will experience immediate dilution due to (i) the issuance of securities to existing Oak Hill Bio security holders and investors in the proposed PIPE Investment in connection with the proposed Business Combination, and (ii) additional sources of dilution upon exercise or conversion of securities that will be issued in connection with or following the proposed Business Combination (for instance, any securities issued in connection with the post-closing combined company equity plan or employee share purchase plan), in each case potentially entitling recipients of such securities to a significant voting stake in the post-closing combined company. • If RAC III does not consummate an initial business combination within the combination period (24 months from the closing of the Initial Public Offering, currently May 21, 2028, the "Combination Period"), as may be extended at the option of Research Alliance Holdings III, LLC (the "Sponsor"), its public shareholders may receive only their pro rata portion of the funds in RAC III's trust account that are available for distribution to its public shareholders. • There are no assurances that RAC III will be able to complete the proposed Business Combination prior to the expiration of the Combination Period. • Oak Hill Bio's or the post-closing combined company's stockholders cannot be certain of the value of the merger consideration they will receive until the closing of the proposed Business Combination. • Because there are no current plans to pay cash dividends on the common stock of the post-closing combined company for the foreseeable future, you may not receive any return on investment unless you sell your RAC III Class A ordinary shares (Nasdaq: RACC) or the common stock of the post-closing combined company at a price greater than what you paid for it. • RAC III, Oak Hill Bio and the post-closing combined company expect to incur substantial transaction fees and costs in connection with the proposed Business Combination and the integration of their businesses. • The costs related to the proposed Business Combination could be significantly higher than currently anticipated. • RAC III's, Oak Hill Bio's or the post-closing combined company's business and operations could be negatively affected, or the proposed Business Combination may be delayed or prevented from being completed, if they become subject to any securities litigation or shareholder activism.

CORPORATE Risk Factors (6 of 7) Risks Related to the Business Combination (cont.) • In connection with the proposed Business Combination, the Sponsor (Research Alliance Holdings III, LLC) and RAC III's directors, executive officers, advisors and their respective affiliates may elect to purchase Class A ordinary shares of RAC III from public shareholders, which may reduce the public "float" of RAC III's Class A ordinary shares. • The Nasdaq Stock Market LLC may delist RAC III's Class A ordinary shares (Nasdaq: RACC) from its exchange prior to the closing of the Business Combination or Nasdaq may not list the post-closing combined company's securities on its exchange, including the shares issued in connection with the proposed PIPE Investment, which could limit investors' ability to make transactions in the post-closing combined company's securities and subject the post-closing combined company to additional trading restrictions. • The securities issued in the proposed PIPE Investment will not initially be registered with the SEC, and prior to such registration cannot be transferred or resold except in a transaction exempt from or not subject to the registration requirements of the Securities Act and applicable state securities laws. • There can be no assurance that the post-closing combined company will be able to comply with Nasdaq's continued listing standards. • Following the closing of the proposed Business Combination, an active trading market for the common stock of the post-closing combined company may not be available on a consistent basis to provide stockholders with adequate liquidity. The share price may be extremely volatile and shareholders could lose a significant part of their investment. • If, following the proposed Business Combination, securities or industry analysts do not publish or cease publishing reports about the post-closing combined company, its business, or its market, or if they change their recommendations regarding the post-closing combined company's securities adversely, the price and trading volume of the securities of the post-closing combined company could decline. • The benefits of the proposed Business Combination may not be realized to the extent currently anticipated by RAC III, Oak Hill Bio and the post-closing combined company, or at all. The ability to recognize any such benefits may be affected by, among other things, competition, the ability of the post-closing combined company to grow and manage growth profitably, maintain relationships with collaborators and suppliers and retain its management and key employees. If the proposed Business Combination's benefits do not meet the expectations of investors, shareholders or financial analysts, the market price of RAC III's or the post-closing combined company's securities may decline. • The proposed Business Combination will result in changes to the composition of the board of directors of Oak Hill Bio and the composition of the board of directors of the post-closing combined company, which may affect the strategy of the post-closing combined company. • The ability of RAC III, Oak Hill Bio and the post-closing combined company to successfully effect the proposed Business Combination and to be successful thereafter will be dependent upon the efforts of certain key personnel, including Oak Hill Bio's key personnel. The loss of key personnel could negatively impact the operations and profitability of the post-closing combined company and its financial condition could suffer as a result. • The post-closing combined company does not have experience operating as a public company subject to U.S. federal securities laws and may not be able to adequately develop and implement the governance, compliance, risk management and control infrastructure and culture required for a public company, including compliance with the Sarbanes Oxley Act • RAC III is currently an "emerging growth company" within the meaning of the Securities Act, and if the post-closing combined company takes advantage of certain exemptions from disclosure requirements available to emerging growth companies, this could make the securities of the post-closing combined company less attractive to investors and may make it more difficult to compare the post-closing combined company's performance with other public companies. • The requirements of being a public company may strain the post-closing combined company's resources, incur increased costs and distract its management, which could make it difficult to manage its business, particularly after the post- closing combined company is no longer an emerging growth company. • Subsequent to the completion of the proposed Business Combination, the post-closing combined company may be required to take write-downs or write-offs, restructuring and impairment or other charges that could have a significant negative effect on its financial condition, results of operations and stock price, which could cause you to lose some or all of your investment. • As a private company, Oak Hill Bio has not been required to document and test its internal controls over financial reporting nor has management been required to certify the effectiveness of its internal controls and its auditors have not been required to opine on the effectiveness of its internal control over financial reporting. As such, material weaknesses may be identified in Oak Hill Bio's or the post-closing combined company's internal control over financial reporting that could lead to errors in the post-closing combined company's financial reporting, which could adversely affect the post-closing combined company's business and the market price of its securities. • If the post-closing combined company fails to maintain an effective system of disclosure controls and internal controls over financial reporting, its ability to produce timely and accurate financial statements or comply with applicable regulations could be impaired. • If the post-closing combined company's estimates or judgments relating to its critical accounting standards prove to be incorrect, or such standards change over time, its results of operations could be adversely affected. • Because the post-closing combined company will become a publicly traded company by virtue of mergers in connection with the proposed Business Combination as opposed to an underwritten initial public offering, there are no underwriters involved in the process, which could result in less diligence being conducted on Oak Hill Bio or the post-closing combined company than in an underwritten initial public offering.

CORPORATE Risk Factors (7 of 7) Risks Related to the Business Combination (cont.) • RAC III's public shareholders can redeem some or all of the funds held in RAC III's trust account, and significant redemptions could materially impact the post-closing combined company's cash position and runway. • The ability of RAC III's public shareholders to exercise redemption rights with respect to a large number of RAC III's public shares may not allow the post-closing combined company to complete the most desirable business combination, fully fund Oak Hill Bio's business plan, or changes thereto, or optimize the capital structure of the post-closing combined company. • Past performance by RAC III's management team or their affiliates, including RA Capital Management, Therapeutics Acquisition Corp. d/b/a Research Alliance Corp. I, Research Alliance Corp. II or their respective business combination targets, may not be indicative of future performance of an investment in RAC III or the post-closing combined company. • The post-closing combined company's governing documents may include provisions that may discourage takeover attempts. • Oak Hill Bio's operating and financial results, which were presented to the RAC III board of directors, may not prove accurate. • Activities taken by existing RAC III shareholders to increase the likelihood of approval of the proposed Business Combination proposal and the other proposals to be described in the proxy statement/prospectus that will be filed in connection with the proposed Business Combination could have a depressive effect on RAC III's share price. • Upon executing a definitive agreement with respect to the proposed Business Combination by and among Oak Hill Bio, RAC III and the post-closing combined company, RAC III may be prohibited from entering into certain transactions that might otherwise be beneficial to it or its shareholders. • The proposed Business Combination may be completed even though material adverse effects may result from the announcement of the proposed Business Combination, industry-wide changes, and other causes. • Delays in completing the proposed Business Combination may substantially reduce the expected benefits of the proposed Business Combination. • Oak Hill Bio has, and the post-closing combined company will have, broad discretion in the use of cash on hand and may not use it effectively.
