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:

For ease of administration, this single Subscription Agreement is being executed so as to enable each Subscriber identified on the signature page to enter into a Subscription Agreement, severally, but not jointly. The parties agree that (i) this Subscription Agreement shall be treated as if it were a separate agreement with respect to each Subscriber listed on the signature page, as if each Subscriber entity had executed a separate Subscription Agreement naming only itself as Subscriber, and (ii) no Subscriber listed on the signature page shall have any liability under the Subscription Agreement for the obligations of any Other Subscriber so listed. The decision of Subscriber to purchase the Subscribed Shares pursuant to this Subscription Agreement has been made by Subscriber independently of any Other Subscriber or any other investor 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 Issuer, Oculis 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 or other investors as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that Subscriber and Other Subscribers or other investors 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 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.

1.   Subscription. Subject to the terms and conditions hereof, at the Closing (as defined below), Subscriber hereby agrees, to subscribe for and purchase, and the Issuer hereby agrees to issue and sell to Subscriber, upon the payment of the Purchase Price, the Subscribed Shares (such subscription and issuance, the “Subscription”). Notwithstanding anything herein to the contrary, the consummation of the Subscription is contingent upon the substantially concurrent occurrence of the Acquisition Closing as further described herein. Each of the parties hereto acknowledge and agree that the Subscribed Shares to be issued pursuant hereto shall initially be shares of a Cayman Islands exempted company and that such shares shall, in connection with the Acquisition Closing, be exchanged for ordinary shares in a Swiss corporation.

2.   Representations, Warranties and Agreements.

2.1.   Subscriber’s Representations, Warranties and Agreements. To induce the Issuer to issue the Subscribed Shares, Subscriber hereby represents and warrants to the Issuer and acknowledges and agrees with the Issuer, as of the date hereof and as of the Closing Date, as follows:

2.1.1.   Subscriber has been duly formed or incorporated and is validly existing in good standing under the laws of its jurisdiction of incorporation or formation, with power and authority to enter into, deliver and perform its obligations under this Subscription Agreement.

2.1.2.   This Subscription Agreement has been duly authorized, validly executed and delivered by Subscriber. Assuming that this Subscription Agreement constitutes the valid and binding agreement of the Issuer, this Subscription Agreement is the valid and binding obligation of Subscriber, and is enforceable against Subscriber in accordance with its terms, except as may be limited or otherwise affected by (i) bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium or other laws relating to or affecting the rights of creditors generally, and (ii) principles of equity, whether considered at law or equity.

2.1.3.   The execution, delivery and performance by Subscriber of this Subscription Agreement and the consummation of the transactions contemplated herein do not and will not (i) result in any violation of the provisions of the organizational documents of Subscriber or any of its subsidiaries, (ii) result in any violation of any statute or any judgment, order, rule or regulation of any court or governmental agency or body, domestic or foreign, having jurisdiction over Subscriber that would reasonably be expected to have a material adverse effect on the legal authority and ability of Subscriber to enter into and timely perform its obligations under this Subscription Agreement (a “Subscriber Material Adverse Effect”) or (iii) 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 Subscriber or any of its subsidiaries pursuant to the terms of any indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument

to which Subscriber or any of its subsidiaries is a party or by which Subscriber or any of its subsidiaries is bound or to which any of the property or assets of Subscriber or any of its subsidiaries is subject, which would reasonably be expected to have a Subscriber Material Adverse Effect.

2.1.4.   Subscriber (i) (a) is a “qualified institutional buyer” (as defined in Rule 144A under the Securities Act) or an institutional “accredited investor” (within the meaning of Rule 501(a)(1), (2), (3), or (7) under the Securities Act), (b) is an Institutional Account as defined in FINRA Rule 4512(c) and (c) is a sophisticated institutional investor, experienced in investing in transactions of the type contemplated by this Subscription Agreement and capable of evaluating investment risks independently, both in general and with regard to all transactions and investment strategies involving a security or securities, including its participation in the Subscription, in each case, satisfying the applicable requirements set forth on Schedule I, (ii) has exercised independent judgment in evaluating its participation in the purchase of the Subscribed Shares, (iii) is acquiring the Subscribed Shares only for its own account and not for the account of others, or if Subscriber is subscribing for the Subscribed Shares as a fiduciary or agent for one or more investor accounts, each owner of such account is a qualified institutional buyer, and Subscriber has full investment discretion with respect to each such account, and the full power and authority to make the acknowledgements, representations, warranties and agreements herein on behalf of each owner of each such account, for investment purposes only and not with a view to any distribution of the Subscribed Shares in any manner that would violate the securities laws of the United States or any other applicable jurisdiction and (iv) is not acquiring the Subscribed Shares with a view to, or for offer or sale in connection with, any distribution thereof in violation of the Securities Act (and shall provide the requested information on Schedule I following the signature page hereto). Subscriber has determined based on its own independent review and such professional advice as it deems appropriate that its purchase of the Subscribed Shares and participation in the Subscription (i) are fully consistent with its financial needs, objectives and condition, and (ii) comply and are fully consistent with all investment policies, guidelines and other restrictions applicable to it (if any). Subscriber is not an entity formed for the specific purpose of acquiring the Subscribed Shares. Subscriber understands that the offering of the Subscribed Shares meets (i) the exemptions from filing under FINRA Rule 5123(b)(1)(A) and (C) or (J) and (ii) the institutional customer exemption under FINRA Rule 2111(b).

2.1.5.   Subscriber understands that the Subscribed Shares are being offered in a transaction not involving any public offering within the meaning of the Securities Act and that the Subscribed Shares have not been registered under the Securities Act or the securities laws of any other jurisdiction. Except in respect of any stock lending program, Subscriber understands that the Subscribed Shares may not be resold, transferred, pledged or otherwise disposed of by Subscriber absent an effective registration statement under the Securities Act, except (i) to the Issuer or a subsidiary thereof, (ii) to non-U.S. persons pursuant to offers and sales that occur solely outside the United States within the meaning of Regulation S under the Securities Act or (iii) pursuant to another applicable exemption from the registration requirements of the Securities Act, and in each of cases ‎(i) and ‎(iii), in accordance with any applicable

securities laws of the states and other jurisdictions of the United States, and that the Subscribed Shares shall be subject to a legend to such effect (provided that such legends will be eligible for removal upon compliance with the relevant resale provisions of Rule 144 and as set forth in this Subscription Agreement). Subscriber acknowledges that the Subscribed Shares will not be immediately eligible for offer, resale, transfer, pledge or disposition pursuant to Rule 144 promulgated under the Securities Act until at least one year from the filing by the Issuer of the “Form 10 information” after the closing of the Business Combination and that the provisions of Rule 144(i) will generally apply to the Subscribed Shares. Subscriber understands and agrees that the Subscribed Shares will be subject to the foregoing restrictions and, as a result, Subscriber may not be able to readily resell the Subscribed Shares and may be required to bear the financial risk of an investment in the Subscribed Shares for an indefinite period of time. Subscriber understands that it has been advised to consult independent legal counsel prior to making any offer, resale, pledge or transfer of any of the Subscribed Shares. Subscriber has determined based on its own independent review and such professional advice as it deems appropriate that the Subscribed Shares are a suitable investment for Subscriber, notwithstanding the substantial risks inherent in investing in or holding the Subscribed Shares, 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 Issuer. Subscriber acknowledges specifically that a possibility of total loss exists. Subscriber will not look to the Placement Agent for all or part of any such loss or losses Subscriber may suffer.

2.1.6.   Subscriber understands and agrees that Subscriber is purchasing the Subscribed Shares directly from the Issuer. Subscriber further acknowledges that there have been no representations, warranties, covenants or agreements made to Subscriber by the Issuer, Oculis, the Placement Agent (as defined below) or any of its affiliate or any control persons, officers, directors, employees, partners, agents or representatives, expressly or by implication, other than, in the case of the Issuer only, those representations, warranties, covenants and agreements expressly set forth in this Subscription Agreement. Subscriber understands that certain financial information (whether historical or in the form of financial forecasts or projections) of the Issuer and Oculis have been prepared and reviewed solely by the Issuer, Oculis and their respective officers, directors and employees, as applicable, and have not been reviewed by any outside party or, except for the financial statements as expressly set forth in the Registration Statement (as defined below), certified or audited by an independent third-party auditor or audit firm.

2.1.7.   Subscriber does not have, as of the date hereof, and during the 30-day period immediately prior to the date hereof such Subscriber has not, and during the period beginning as of the date hereof until and including the date that is two trading days following the Closing such Subscriber will not have, entered into, any “put equivalent position” as such term is defined in Rule 16a-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) or short sale positions with respect to the securities of the Issuer.

2.1.8.   If Subscriber is an employee benefit plan that is subject to Title I of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”),

Subscriber represents and warrants that its acquisition and holding of the Subscribed Shares will not constitute or result in a non-exempt prohibited transaction under Section 406 of ERISA, Section 4975 of the Internal Revenue Code of 1986, as amended (the “Code”), or any applicable other federal, state, local, non-U.S. or other laws or regulations that are similar to such provisions of ERISA or the Code (collectively, “Similar Laws”).

2.1.9.   To the Subscriber’s knowledge, no disclosure or offering document has been prepared in connection with the offer and sale of the Subscribed Shares by Arctica Finance hf. (the “Placement Agent”). In making its decision to purchase the Subscribed Shares, Subscriber represents that it has relied solely upon independent investigation made by Subscriber and the representations, warranties and covenants of the Issuer contained in this Subscription Agreement. Without limiting the generality of the foregoing, Subscriber has not relied on any statements or other information provided by anyone (including the Placement Agent), other than the Issuer and its representatives concerning the Issuer or the Subscribed Shares or the offer and sale of the Subscribed Shares. Subscriber acknowledges and agrees that Subscriber has received access to and has 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, including with respect to the Issuer, Oculis, and the Transactions.

Subscriber represents and warrants it is relying exclusively on its own investment analysis and due diligence (including professional advice it deems appropriate) with respect to the Subscription, the Transactions, the Subscribed Shares and the business, condition (financial and otherwise), management, operations, properties and prospects of the Issuer and Oculis including but not limited to all business, legal, regulatory, accounting, credit and tax matters. Subscriber further acknowledges that Subscriber has not relied upon the Placement Agent in connection with Subscriber’s due diligence review of the offering of the Subscribed Shares and the Issuer.

2.1.10.   Subscriber acknowledges and agrees that (a) it has been informed that the Placement Agent is acting solely as placement agent in connection with the Subscription and is not acting as an underwriter or in any other capacity in connection with the Subscription and is not and shall not be construed as a fiduciary for Subscriber, the Issuer, Oculis or any other person or entity in connection with the Transactions, (b) the Placement Agent has not made and will not make any representation or warranty, whether express or implied, of any kind or character and have not provided any advice or recommendation in connection with the Subscription and the Transactions, in each case, to Subscriber and such advice or recommendation is not necessary or desired, (c) the Placement Agent will have no responsibility to Subscriber with respect to (i) any representations, warranties or agreements made by any person or entity under or in connection with the Subscription and the Transactions or any of the documents furnished

Subscriber further acknowledges that BofA Securities, Inc. is acting as financial advisor to Oculis in connection with the Transactions and that SVB Securities LLC is acting as Oculis’ capital markets advisor in connection with the Transactions. Subscriber waives and releases any claim that it or its affiliates may have against any Placement Agent and its affiliates and any control persons, officers, directors, employees, partners, agents or representatives of that Placement Agent and its affiliates with respect to any actual or perceived conflict of interest that may arise from such Placement Agent’s engagements as indicated in the immediately preceding sentence, in the context of such Placement Agent’s engagement by the Issuer as the Issuer’s placement agent in connection with the Subscription. The Issuer and Oculis are solely responsible for paying any fees or other commission owed to the Placement Agent in connection with the Subscription or the Transactions.

2.2.17.   The Issuer is not (i) a person or entity named on the List of Specially Designated Nationals and Blocked Persons administered by OFAC or in any Executive Order issued by the President of the United States and administered by OFAC, on any Sanctions List, or a person or entity designated by any OFAC sanctions program, (ii) directly or indirectly 50% or more owned or otherwise controlled by, or acting on behalf of, one or more persons on a Sanctions List, (iii) organized, incorporated, established or located in Cuba, Iran, North Korea, Syria, Venezuela, the Crimea region of Ukraine, the so-called Donetsk People’s Republic, the so-called Luhansk People’s Republic, any other Covered Region of Ukraine identified pursuant to Executive Order 14065, or any other country or territory embargoed or subject to substantial trade restrictions by the United States, the United Nations Security Council, the European Union, Switzerland, HMT, any individual European member state or the United Kingdom, or (iv) a non-U.S. shell bank or providing banking services indirectly to a non-U.S. shell bank (each person described in clauses (i) to (v), a “Blocked Person”). The representations, warranties and undertakings in this Section 2.2.17 will not apply to any party hereto to which the Blocking Regulation applies, if and to the extent that such representation, warranty or undertaking is or would be invalid or unenforceable by reason of breach of any provision of the Blocking Regulation (or any law or regulation implementing such Blocking Regulation in any member state of the European Union or the United Kingdom). If the Issuer is a financial institution subject to the BSA/PATRIOT Act, Issuer represents that it maintains policies and procedures reasonably designed to comply with applicable obligations under the BSA/PATRIOT Act. The Issuer also represents that, to the extent required, it maintains policies and procedures reasonably designed to ensure compliance with sanctions programs administered by OFAC, the United Nations Security Council, the European Union, Switzerland, HMT, any European Union member state and the United Kingdom, including for the screening of its investors against the Sanctions List and the OFAC sanctions programs. Issuer further represents and warrants that, to the extent required, it maintains policies and procedures reasonably designed to ensure that the funds held by Issuer were legally derived.

2.2.18.   No part of the proceeds from the Subscription constitutes or will constitute funds obtained on behalf of any Blocked Person or will otherwise be used by the Issuer, directly or indirectly, (i) in connection with any unauthorized investment in, or any unauthorized transactions or dealings with, any Blocked Person, or (ii) otherwise in violation of sanctions enforced by the United States, the European Union, Switzerland, Her Majesty’s Treasury (HMT) or any other relevant sanctions authority.

2.2.19.   Neither the Issuer and its executives and directors, nor any of its subsidiaries and their respective officers and directors, is or has been (i) charged with, or convicted of bribery or any other anticorruption related activity under any applicable law or regulation in any applicable country or jurisdiction, including but not limited to, the U.S. Foreign Corrupt Practices Act (collectively, “Anti-Corruption Laws”), (ii) under investigation by any governmental authority for possible violation of Anti-Corruption Laws, (iii) assessed civil or criminal penalties under any Anti-Corruption Laws or (iv) the target of sanctions imposed by the United Nations, the European Union, Switzerland or the United Kingdom.

2.2.20.   Neither the Issuer and its officers and directors, nor any of its subsidiaries and their respective officers and directors, within the last five years, directly or indirectly offered, promised, given, paid or authorized the offer, promise, giving or payment of anything of value to any governmental authority official or a commercial counterparty for the purposes of: (i) influencing any act, decision or failure to act by such governmental authority official in his or her official capacity or such commercial counterparty, (ii) inducing a governmental authority official to do or omit to do any act in violation of the governmental authority official’s lawful duty, or (iii) inducing a governmental authority official or a commercial counterparty to use his or her influence with a government or instrumentality to affect any act or decision of such government or entity; in each case in order to obtain, retain or direct business or to otherwise secure an improper advantage in violation of any applicable law or regulation or which would cause any such person to be in violation of any law or regulation applicable to such person.

2.2.21.   No part of the proceeds from the Subscription will be used, directly or indirectly, for any improper payments, including bribes, to any governmental authority official or commercial counterparty in order to obtain, retain or direct business or obtain any improper advantage. The Issuer has established procedures and controls which it reasonably believes are adequate (and otherwise comply with applicable law) to ensure that the Issuer is and will continue to be in compliance with all applicable current and future Anti-Corruption Laws.

2.2.22.   The Issuer is not in default or violation (and no event has occurred which, with notice or the lapse of time or both, would constitute a default or violation) of any term, condition or provision of (i) the organizational documents of the Issuer, (ii) any loan or credit agreement, guarantee, note, bond, mortgage, indenture, lease or other agreement, permit, franchise or license to which, as of the date of this Subscription Agreement, the Issuer is a party or by which the Issuer’s properties or assets are bound or (iii) any statute or any judgment, order, rule or regulation of any court or governmental agency, taxing authority or regulatory body, domestic or foreign, having jurisdiction over the Issuer or any of its properties, except, in the case of clauses (ii) and (iii), for defaults or violations that have not had and would not be reasonably likely to have, individually or in the aggregate, an Issuer Material Adverse Effect.

2.2.23.   The Issuer is in compliance with all applicable laws, except where such non-compliance would not be reasonably likely to have an Issuer Material

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

2.2.24.   As of the date hereof, the issued and outstanding Class A ordinary shares, $0.0001 par value, of the Issuer (the “Class A Shares”) are registered pursuant to Section 12(b) of the Exchange Act, and are listed for trading on Nasdaq under the symbol “EBAC”. There is no suit, action, proceeding or investigation pending or, to the knowledge of the Issuer, threatened against the Issuer by Nasdaq or the Commission with respect to any intention by such entity to deregister the Class A Shares or prohibit or terminate the listing of the Class A Shares on Nasdaq. The Issuer has taken no action that is designed to terminate the registration of the Class A Shares under the Exchange Act or the listing of the Class A Shares on Nasdaq.

2.2.25.   The Business Combination Agreement has been or will be, as applicable, duly and validly authorized, executed and delivered by the Issuer, Oculis, New Parent, Merger Sub 1, Merger Sub 2 and Merger Sub 3 and, assuming due authorization, execution and delivery by the other parties thereto, constitutes or will constitute, as applicable, a valid and binding agreement of the Issuer, Oculis, New Parent, Merger Sub 1, Merger Sub 2 and Merger Sub 3 enforceable against the Issuer, Oculis, New Parent, Merger Sub 1, Merger Sub 2 and Merger Sub 3 in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency or similar laws affecting the enforcement of creditors’ rights generally or by equitable principles relating to enforceability. The representations and warranties of the Issuer set forth in the Business Combination Agreement are true and correct in all material respects (or, if any such representations or warranties are qualified by materiality, material adverse effect or similar language, true and correct in all respects). To the knowledge of the Issuer, the representations and warranties of Oculis contained in the Business Combination Agreement are true and accurate in all material respects (or, if any such representations or warranties are qualified by materiality, material adverse effect or similar language, true and correct in all respects).

3.   Settlement Date and Delivery.

3.1.   Closing. The closing of the Subscription contemplated hereby (the “Closing”) shall occur on the Closing Start Date but subject to, the Acquisition Closing (the date of the Closing, the “Closing Date”). Upon written notice from (or on behalf of) the Issuer to Subscriber (the “Closing Notice”) at least five (5) Business Days prior to the date that the Issuer reasonably expects all conditions to the Acquisition Closing to be satisfied (the “Expected Closing Date”), Subscriber shall deliver to the Issuer no later than two (2) Business Days prior to the Expected Closing Date (i) the Purchase Price for the Subscribed Shares by wire transfer of United States dollars in immediately available funds to the account specified by the Issuer in the Closing Notice, such funds to be held by the Issuer in escrow until the Closing and (ii) any other information that is reasonably requested in the Closing Notice in order for Issuer to issue the Subscribed Shares including, without limitation, the legal name of the person in whose name

such Subscribed Shares are to be issued, and if applicable, and a duly executed Internal Revenue Service Form W-9 or the applicable Internal Revenue Service Form W-8, as applicable. On the Closing Date, the Issuer shall issue to Subscriber (or the funds and accounts designated by Subscriber if so designated by Subscriber, or its nominee in accordance with its delivery instructions) or to a custodian designated by Subscriber, as applicable, the Subscribed Shares, free and clear of any liens or other restrictions whatsoever (other than those arising under state or federal securities laws), which Subscribed Shares, unless otherwise determined by the Issuer, shall be uncertificated, with record ownership reflected only in the register of shareholders of the Issuer and shall provide evidence of such issuance from the Issuer’s transfer agent showing Subscriber as the owner of the Subscribed Shares within two (2) Business Days of the Closing Date. If the Acquisition Closing is not consummated within two (2) Business Days after the Expected Closing Date, the Issuer shall promptly (but no later than one (1) Business Day thereafter) return the Purchase Price to Subscriber by wire transfer of United States dollars in immediately available funds to an account specified by Subscriber, and the Subscribed Shares shall be cancelled. Notwithstanding such return, (i) a failure to close on the Expected Closing Date shall not, by itself, be deemed to be a failure of any of the conditions to Closing set forth in this Section 3 to be satisfied or waived on or prior to the Closing Date, and (ii) unless and until this Subscription Agreement is terminated in accordance with Section 5 hereof, Subscriber shall remain obligated (A) to redeliver funds on the new Closing Date to the Issuer following the Issuer’s delivery to Subscriber of a new Closing Notice and (B) to consummate the Closing upon satisfaction of the conditions set forth in this Section 3. For purposes of this Subscription Agreement, “Business Day” means any day that, in New York, New York and Lausanne, Switzerland, is neither a legal holiday nor a day on which banking institutions are generally authorized or required by law or regulation to close.

3.2.   Conditions to Closing of the Issuer.

3.2.1.   Representations and Warranties Correct. The representations and warranties made by Subscriber in Section ‎2.1 hereof shall be true and correct in all material respects when made (unless they specifically speak as of another date in which case they shall be true and correct in all material respects as of such date) (other than representations and warranties that are qualified as to materiality or Subscriber Material Adverse Effect, which representations and warranties shall be true and correct in all respects), and shall be true and correct in all material respects on and as of the Closing Date (unless they specifically speak as of another date in which case they shall be true and correct in all material respects as of such date) (other than representations and warranties that are qualified as to materiality or Subscriber Material Adverse Effect, which representations and warranties shall be true in all respects) with the same force and effect as if they had been made on and as of said date, but in each case without giving effect to consummation of the Transactions.

3.2.2.   Compliance with Covenants. Subscriber shall have performed, satisfied and complied in all material respects with the covenants, agreements and

conditions required by this Subscription Agreement to be performed, satisfied or complied with by Subscriber at or prior to the Closing.

3.2.3.   Closing of the Transactions. All conditions precedent to each of the Issuer’s and Oculis’s obligations to consummate, or cause to be consummated, the Acquisition Closing shall have been satisfied or waived by the party entitled to the benefit thereof under the Business Combination Agreement (other than those conditions that may only be satisfied at the consummation of the Acquisition Closing, but subject to satisfaction or waiver by such party of such conditions as of the consummation of the Acquisition Closing), and the Primary Transactions will be consummated immediately following the Closing (or in the case of the Company Share Contribution, upon the timing set forth in the Business Combination Agreement).

3.2.4.   Legality. There shall not be in force any order, judgment, injunction, decree, writ, stipulation, determination or award, in each case, entered by or with any governmental authority, statute, rule or regulation enjoining or prohibiting the consummation of the transactions contemplated by this Subscription Agreement or the Transactions and no such governmental authority shall have instituted or threatened in writing a proceeding seeking to impose any such restraint or prohibition.

The representations and warranties made by the Issuer in Section ‎2.2 hereof shall be true and correct in all material respects when made (unless they specifically speak as of another date in which case they shall be true and correct in all material respects as of such date) (other than representations and warranties that are qualified as to materiality or Issuer Material Adverse Effect, which representations and warranties shall be true and correct in all respects), and shall be true and correct in all material respects on and as of the Closing Date (unless they specifically speak as of another date in which case they shall be true and correct in all material respects as of such date) (other than representations and warranties that are qualified as to materiality or Issuer Material Adverse Effect, which representations and warranties shall be true and correct in all respects) with the same force and effect as if they had been made on and as of said date, but in each case without giving effect to consummation of the Transactions.

3.3.2.   Compliance with Covenants. The Issuer shall have performed, satisfied and complied in all respects with the covenants, agreements and conditions required by this Subscription Agreement to be performed, satisfied or complied with by the Issuer at or prior to the Closing, except where the failure of such performance or compliance would not or would not reasonably be expected to prevent, materially delay, or materially impair the ability of the Issuer to consummate the Closing.

3.3.3.   Closing of the Transactions. All conditions precedent to the consummation of the Acquisition Closing shall have been satisfied or waived by the party entitled to the benefit thereof under the Business Combination Agreement (other than those conditions that may only be satisfied at the consummation of the Acquisition Closing, but subject to satisfaction or waiver by such party of such conditions as of the consummation of the Acquisition Closing), and the Primary Transactions will be consummated immediately following the Closing (or in the case of the Company Share Contribution, upon the timing set forth in the Business Combination Agreement). Except to the extent consented to in writing by Subscriber, the Business Combination Agreement (as filed with the Commission on or shortly after the date hereof) shall not have been amended, modified, supplemented or waived in a manner that would reasonably be expected to materially and adversely affect the economic benefits that Subscriber would reasonably expect to receive under this Subscription Agreement. New Parent shall have assumed, or shall have agreed to assume, all of the obligations of the Issuer hereunder (including, for the avoidance of doubt, standing in the place of the “Issuer” for purposes of Section 4 hereunder). There shall have been no amendment, waiver or modification to the Other Subscription Agreements that materially benefits any such Other Subscriber thereunder (other than terms particular to the legal or regulatory requirements of such Other Subscriber or its affiliates or related persons) unless Subscriber has been offered substantially the same benefits.

3.3.4.   Legality. There shall not be in force any order, judgment, injunction, decree, writ, stipulation, determination or award, in each case, entered by or with any governmental authority, statute, rule or regulation enjoining or prohibiting consummation of the transactions contemplated by this Subscription Agreement or the Transactions and no such governmental authority shall have instituted or threatened in writing a proceeding seeking to impose any such restraint or prohibition.

3.3.5.   Listing. No suspension of the qualification of the Ordinary Shares for offering or sale or trading in any jurisdiction, and no suspension or removal from listing of the Ordinary Shares on Nasdaq, and no initiation or threatening of any proceedings for any of such purposes or delisting, shall have occurred, and the Subscribed Shares shall be approved for listing on Nasdaq, as applicable, subject to official notice of issuance.

3.4.   From the date hereof until the Closing Date, the Issuer shall provide prompt written notice to Subscriber of any (i) amendment, modification or waiver of any provision of the Business Combination Agreement that would reasonably be expected to materially and adversely affect the economic benefits that Subscriber or the Issuer would reasonably expect to receive under this Subscription Agreement or (ii) any declaration by the Issuer of a Material Adverse Effect (as defined in the Business Combination Agreement) under the Business Combination Agreement.

4.   Registration Statement. The Issuer and the Subscriber hereby agree as follows, and the Issuer shall cause New Parent to, and acknowledges and agrees that, following the Acquisition Closing, New Parent shall assume all of the Issuer’s obligations under the following Section 4 of this Subscription Agreement (including, for the avoidance of doubt, standing in the place of the “Issuer” for purposes of the following Section 4 hereunder):

4.1.   The Issuer agrees that, within thirty (30) Business Days after the Acquisition Closing Date (the “Filing Date”), the Issuer will file with the Commission (at the Issuer’s sole cost and expense) a registration statement (the “Registration Statement”) registering the resale of the Subscribed Shares and/or any other equity security (of the Issuer, any successor entity or otherwise) issued or issuable with respect to the Subscribed Shares by way of share split, dividend, distribution, recapitalization, merger, exchange, replacement or similar event or otherwise (the “Registrable Securities”), and the Issuer 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 Issuer that it will “review” the Registration Statement) following the Closing Date and (ii) the tenth (10^th) Business Day after the date the Issuer 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 earlier date, the “Effectiveness Date”); provided, however, that the Issuer’s obligations to include the Registrable Securities in the Registration Statement are contingent upon Subscriber furnishing a completed and executed selling shareholders questionnaire in customary form to the Issuer that contains the information required by Commission rules for a Registration Statement regarding Subscriber, the securities of the Issuer held by Subscriber and the intended method of disposition of the Registrable Securities to effect the registration of the Registrable Securities, and Subscriber shall execute such documents in connection with such registration as the Issuer may reasonably request that are customary of a selling stockholder in similar situations, including providing that the Issuer shall be entitled to postpone and suspend the effectiveness or use of the Registration Statement, if applicable, as permitted hereunder; 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. For purposes of clarification, any failure by the Issuer to file the Registration Statement by the Filing Date or to effect such Registration Statement by the Effectiveness Date shall not otherwise relieve the Issuer of its obligations to file or effect the Registration Statement as set forth above in this Section ‎4. For purposes of this Section ‎4, “Registrable Securities” shall include, as of any date of determination, the Subscribed Shares and any other equity security issued or issuable with respect to the Subscribed Shares by way of share split, dividend, distribution, recapitalization, merger, exchange, replacement or similar event or otherwise, including, for the avoidance of doubt, any equity securities of New Parent issued in exchange for such Subscribed Shares or such other equity securities, and “Subscriber” shall include any person to which the rights under this Section 4 shall have been duly assigned. The Issuer will provide a draft of the Registration Statement to Subscriber for review at least two (2) Business Days in advance of filing the Registration Statement. In no event shall Subscriber be identified as a statutory underwriter in the Registration Statement unless requested by the Commission and consented to by Subscriber. If the Commission requests that Subscriber be identified as a statutory underwriter in the Registration Statement, Subscriber will have an opportunity to withdraw from the Registration Statement. Notwithstanding the foregoing, if the Commission prevents the Issuer from including any or all of the Registrable Securities proposed to be registered for resale 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 applicable shareholders or otherwise, (i) such Registration Statement shall register for resale such number of Subscribed Shares which is equal to the maximum number of Subscribed Shares as is permitted by the

Commission and (ii) the number of Subscribed Shares to be registered for each selling shareholder named in the Registration Statement shall be reduced pro rata among all such selling shareholders; and as promptly as practicable after being permitted to register additional Subscribed Shares under Rule 415 under the Securities Act, the Issuer shall amend the Registration Statement or file a new Registration Statement to register such Subscribed Shares not included in the initial Registration Statement and cause such amendment or Registration Statement to become effective as promptly as practicable.

4.2.   In the case of the registration effected by the Issuer pursuant to this Subscription Agreement, the Issuer shall, upon reasonable request, inform Subscriber as to the status of such registration. At its expense the Issuer shall:

4.2.1.   except for such times as the Issuer is permitted hereunder to suspend the use of the prospectus forming part of a Registration Statement, use its commercially reasonable efforts to keep such registration, and any qualification, exemption or compliance under state securities laws which the Issuer determines to obtain, continuously effective, and to keep the applicable Registration Statement or any subsequent shelf registration statement free of any material misstatements or omissions, until the earlier of the following: (i) the third anniversary of the effectiveness of the Registration Statement, (ii) when Subscriber has sold all of its Registrable Securities pursuant to the Registration Statement or Rule 144 and (iii) the date all Registrable Securities held by the Subscriber may be sold without restriction under Rule 144, including without limitation, any volume and manner of sale restrictions which may be applicable to affiliates under Rule 144 and without the requirement for the Issuer to be in compliance with the current public information required under Rule 144(c)(1) (or Rule 144(i)(2), if applicable); provided, that for as long as the Registration Statement shall remain effective pursuant to the immediately preceding sentence, the Issuer will (a) use commercially reasonable efforts to file all reports, and (b) provide all customary and reasonable cooperation, necessary to (x) enable Subscriber to resell the Registrable Securities pursuant to the Registration Statement or Rule 144, as applicable, and (y) update or amend the Registration Statement as necessary to include the Registrable Securities.

4.2.2.   advise Subscriber, as promptly as practicable but in any event within five (5) Business Days:

(a)   when a Registration Statement or any post-effective amendment thereto has become effective;

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

(c)   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;

(d)   of the receipt by the Issuer 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

(e)   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 Issuer shall not, when so advising Subscriber of such events, provide Subscriber with any material, non-public information regarding the Issuer or subject Subscriber to any duty of confidentiality;

4.2.3.   use its commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of any Registration Statement as soon as reasonably practicable;

4.2.4.   upon the occurrence of any event contemplated in Section ‎4.2.2(e), except for such times as the Issuer is permitted hereunder to suspend, and has suspended, the use of a prospectus forming part of a Registration Statement, the Issuer 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;

4.2.5.   use its commercially reasonable efforts to cause all Subscribed Shares to be listed on each securities exchange or market, if any, on which the Issuer’s Ordinary Shares are then listed;

4.2.6.   allow Subscriber to review and consent to disclosure specifically regarding Subscriber in the Registration Statement on reasonable advance notice (which consent shall not be unreasonably withheld); and

4.2.7.   use its commercially reasonable efforts to take all other steps reasonably necessary to effect the registration of the Registrable Securities and to enable the sale of the Registrable Securities under Rule 144; and

4.2.8.   cause the Issuer’s transfer agent to remove any restrictive legend, at Subscriber’s request, when the Registrable Securities are sold pursuant to Rule 144 under the Securities Act or the Registration Statement or may be sold without restriction

under Rule 144. In connection therewith, if required by the Issuer’s transfer agent and upon receipt of any customary certifications or other documentation reasonably requested by the Issuer, the Issuer will promptly cause an opinion of counsel to be delivered to and maintained with its transfer agent, together with any other authorizations, certificates and directions required by the transfer agent that authorize and direct the transfer agent to issue such Registrable Securities without any such legend.

4.3.   Notwithstanding anything to the contrary in this Subscription Agreement, the Issuer 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, (i) as may be necessary in connection with the preparation and filing of a post-effective amendment to the Registration Statement following the filing of the Issuer’s Annual Report on Form 10-K or 20-F, as applicable, or (ii) if the filing, effectiveness or continued use of any Registration Statement would require the Issuer to make any public disclosure of material non-public information, which disclosure, in the good faith determination of the board of directors of the Issuer, after consultation with counsel to the Issuer, (a) would be required to be made in any Registration Statement in order for the applicable Registration Statement not to contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements contained therein not misleading, (b) would not be required to be made at such time if the Registration Statement were not being filed, and (c) the Issuer has a bona fide business purpose for not making such information public (each such circumstance, a “Suspension Event”); provided, however, that the Issuer may not delay or suspend the Registration Statement on more than two occasions or for more than sixty (60) consecutive calendar days, or more than one hundred twenty (120) total calendar days, in each case, during any three hundred sixty (360) day period. Upon receipt of any written notice from the Issuer (which notice shall not contain any material non-public information regarding the Issuer and which notice shall not be subject to any duty of confidentiality) of the happening of any Suspension Event during the period that the Registration Statement is effective or if 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 immediately discontinue offers and sales of the Subscribed Shares under the Registration Statement (excluding, for the avoidance of doubt, sales conducted pursuant to Rule 144) until Subscriber receives copies of a supplemental or amended prospectus (which the Issuer 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 Issuer that it may resume such offers and sales (which notice shall not contain any material non-public information regarding the Issuer and which notice shall not be subject to any duty of confidentiality). If so directed by the Issuer, Subscriber will deliver to the Issuer or, in Subscriber’s sole discretion destroy, all copies of the prospectus covering the Subscribed Shares in Subscriber’s possession; provided, however, that this obligation to deliver or destroy all copies of the prospectus covering the Subscribed Shares shall not apply (i) to the extent Subscriber is required to retain a copy of such prospectus (a) in order to comply with applicable legal, regulatory, self-regulatory or professional requirements or (b) in accordance with a bona fide pre-existing document retention policy or (ii) to copies stored electronically on archival servers

as a result of automatic data back-up. Subscriber may deliver written notice (an “Opt-Out Notice”) to the Issuer requesting that Subscriber not receive notices from the Issuer otherwise required by this Section 4; provided, however, that Subscriber may later revoke any such Opt-Out Notice in writing. Following receipt of an Opt-Out Notice from Subscriber (unless subsequently revoked), (i) the Issuer shall not deliver any such notices to Subscriber and Subscriber shall no longer be entitled to the rights associated with any such notice and (ii) each time prior to Subscriber’s intended use of an effective Registration Statement, Subscriber will notify the Issuer in writing at least two (2) business days in advance of such intended use, and if a notice of a Suspension Event was previously delivered (or would have been delivered but for the provisions of the preceding sentence) and the related suspension period remains in effect, the Issuer will so notify Subscriber, within one (1) business day of Subscriber’s notification to the Issuer, by delivering to Subscriber a copy of such previous notice of Suspension Event, and thereafter will provide Subscriber with the related notice of the conclusion of such Suspension Event promptly following its availability.

4.4.   The parties agree that:

4.4.1.   The Issuer shall, notwithstanding the termination of this Subscription Agreement, indemnify and hold harmless, to the extent permitted by law, Subscriber (to the extent a selling shareholder under any Registration Statement), the officers, directors, agents, partners, members, managers, shareholders, affiliates, employees and investment advisers of each Subscriber, each person who controls such Subscriber (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act), and the officers, directors, partners, members, managers, shareholders, agents, affiliates, employees and investment advisers of each such controlling person from and against any and all losses, claims, damages, liabilities, costs and expenses (including, without limitation, any reasonable and documented attorneys’ fees of one law firm and one local counsel in each applicable jurisdiction and expenses incurred in connection with defending or investigating any such action or claim) (collectively, “Losses”), as incurred, that arise out of or are based upon (i) any untrue or alleged untrue statement of material fact contained in any Registration Statement (or incorporated by reference therein), prospectus included in any Registration Statement or preliminary prospectus or any amendment thereof or supplement thereto or arising out of or relating to any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus or form of prospectus or supplement thereto, in the light of the circumstances under which they were made) not misleading or (ii) any violation or alleged violation by the Issuer of the Securities Act, Exchange Act or any state securities law or any rule or regulation thereunder, in connection with the performance of its obligations under this Section 4, except insofar as the same are caused by or contained in any information furnished in writing to the Issuer by or on behalf of Subscriber expressly for use therein or Subscriber has omitted a material fact from such information; provided, however, that the indemnification contained in this Section ‎4.4 shall not apply to amounts paid in settlement of any Losses if such settlement is effected without the consent of the Issuer (which consent shall not be unreasonably withheld, conditioned or delayed), nor shall the Issuer be liable for any Losses to the extent they arise out of or are based upon a violation which occurs (A) in reliance upon and in conformity with written information furnished

by Subscriber expressly for use in such Registration Statement or preliminary prospectus or any amendment thereof or supplement thereto, (B) in connection with any failure of such person to deliver or cause to be delivered a prospectus made available by the Issuer in a timely manner, (C) as a result of offers or sales effected by or on behalf of any person by means of a “free writing prospectus” (as defined in Rule 405 under the Securities Act) that was not authorized by the Issuer or (D) in connection with any offers or sales effected by or on behalf of Subscriber in violation of Section ‎4.3 hereof. The Issuer shall notify Subscriber promptly of the institution, threat or assertion of any proceeding arising from or in connection with the transactions contemplated by this Section ‎4 of which the Issuer is aware.

4.4.2.   Subscriber agrees, severally and not jointly with any person that is a party to the Other Subscription Agreements, to indemnify and hold harmless, to the extent permitted by law, the Issuer and the Placement Agent and each of the Issuer’s and the Placement Agent’s respective directors, officers, employees and agents and each person who controls the Issuer and the Placement Agent, as applicable (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act) against any and all Losses, as incurred, that arise out of or result from any untrue or alleged untrue statement of material fact contained in any Registration Statement, prospectus included in any Registration Statement or preliminary prospectus or any amendment thereof or supplement thereto or any omission of a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing by such Subscriber expressly for use therein; provided, however, that the indemnification contained in this Section ‎4.4 shall not apply to amounts paid in settlement of any Losses if such settlement is effected without the consent of Subscriber (which consent shall not be unreasonably withheld, conditioned or delayed). Notwithstanding anything to the contrary herein, in no event shall the liability of Subscriber be greater in amount than the dollar amount of the net proceeds received by Subscriber upon the sale of the Subscribed Shares purchased pursuant to this Subscription Agreement giving rise to such indemnification obligation.

4.4.3.   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 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. An indemnifying party who elects not to assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one 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 (which consent shall not be unreasonably withheld, conditioned or delayed), 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.

4.4.4.   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 and shall survive the transfer of the Subscribed Shares purchased pursuant to this Subscription Agreement. The Issuer shall cause New Parent to, and acknowledges and agrees that, following the Acquisition Closing, New Parent shall, assume the Issuer’s obligations under Section 4.4 of this Subscription Agreement.

4.4.5.   If the indemnification provided under this Section ‎4.4 from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any Losses 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 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 relates to information supplied by, 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 ‎4.4 from any person who was not guilty of such fraudulent misrepresentation. Each indemnifying party’s obligation to make a contribution pursuant to this Section 4.4 shall be individual, not joint and several, and in no event shall the liability of Subscriber be greater in amount than the dollar amount of the net proceeds received by Subscriber upon the sale of the Subscribed Shares purchased pursuant to this Subscription Agreement giving rise to such contribution obligation.

5.   Termination. This Subscription Agreement shall terminate and be void and of no further force and effect, and all rights and obligations of the parties hereunder shall terminate without any further liability on the part of any party in respect thereof, upon the earliest to occur of (i) such date and time as the Business Combination Agreement is validly terminated in

accordance with its terms without being consummated, (ii) upon the mutual written agreement of each of the parties hereto to terminate this Subscription Agreement, (iii) Issuer’s notification to the Subscriber in writing that it has, with the prior written consent of Oculis, abandoned its plans to move forward with the Transactions and/or terminated the Subscriber’s obligations with respect to the subscription without the issuance of the Subscribed Shares having occurred, (iv) at the election of Subscriber following the date that is 30 days after the Acquisition Closing Date (as defined in the Business Combination Agreement as in effect on the date hereof) if the Closing shall not have occurred by such date (provided, that the right to terminate this Subscription Agreement pursuant to this clause (iv) shall not be available to Subscriber if Subscriber’s or its assignee’s breach of any of its covenants or obligations under this Subscription Agreement (or if an affiliate of Subscriber is one of the Subscribers under an Other Subscription Agreement, such other Subscriber’s breach of any of its covenants or obligations under the Other Subscription Agreement) either individually or in the aggregate, shall have proximately caused the failure of the consummation of the Acquisition Closing on or before the such date); provided that nothing herein will relieve any party from liability for any willful breach hereof prior to the time of termination, and each party will be entitled to any remedies at law or in equity to recover losses, liabilities or damages arising from such breach. The Issuer shall promptly notify Subscriber in writing of the termination of the Business Combination Agreement promptly after the termination of such agreement. Upon the termination hereof in accordance with this Section 5, any monies paid by Subscriber to the Issuer in connection herewith shall promptly (and in any event within two (2) Business Days) be returned in full to Subscriber by wire transfer of U.S. dollars in immediately available funds to the account specified by Subscriber, without any deduction for or on account of any tax withholding, charges or set-off, whether or not the Transaction shall have been consummated.

6.   Miscellaneous.

6.1.   Further Assurances. At the Closing, the parties hereto shall execute and deliver such additional documents and take such additional actions as the parties reasonably may deem to be practical and necessary in order to consummate the Subscription as contemplated by this Subscription Agreement.

6.1.1.   Subscriber acknowledges that the Issuer and the Placement Agent will rely on the acknowledgments, understandings, undertakings, agreements, representations and warranties made by Subscriber contained in this Subscription Agreement. Prior to the Closing, Subscriber agrees to promptly notify the Issuer and the Placement Agent if any of the acknowledgments, understandings, undertakings, agreements, representations and warranties made by Subscriber set forth herein are no longer accurate in all material respects. The Issuer acknowledges that Subscriber and the Placement Agent will rely on the acknowledgments, understandings, undertakings, agreements, representations and warranties made by the Issuer contained in this Subscription Agreement. Prior to the Closing, the Issuer agrees to promptly notify Subscriber and the Placement Agent if any of the acknowledgments, understandings, undertakings, agreements, representations and warranties made by Issuer set forth herein are no longer accurate in all material respects (other than those acknowledgments, understandings, agreements, undertakings, representations and warranties qualified by

materiality, in which case the Issuer shall notify Subscriber and the Placement Agent if they are no longer accurate in any respect).

6.1.2.   Each of the Issuer, Subscriber and the Placement Agent is entitled to rely upon this Subscription Agreement and 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.

6.1.3.   The Issuer may request from Subscriber such additional information as the Issuer may reasonably deem necessary to evaluate the eligibility of Subscriber to acquire the Subscribed Shares, and Subscriber shall provide such information as may be reasonably requested, to the extent within Subscriber’s possession and control or otherwise readily available to Subscriber, provided that the Issuer agrees to keep confidential any such information provided by Subscriber.

6.1.4.   Each of Subscriber and the Issuer shall pay all of its own respective expenses in connection with this Subscription Agreement and the transactions contemplated herein (it being agreed that all expenses related to any Registration Statement are for the account of the Issuer to the extent provided in Section 4, and the Issuer shall be responsible for the fees of its transfer agent and all of DTC’s fees associated with the issuance of the Subscribed Shares).

6.1.5.   Each of Subscriber and the Issuer shall take, or cause to be taken, all actions and do, or cause to be done, all things necessary, proper or advisable to consummate the transactions contemplated by this Subscription Agreement on the terms and conditions described therein no later than immediately prior to the Acquisition Closing.

6.2.   Subscriber hereby acknowledges and agrees that, except in respect of any stock lending program, it will not, nor will any person acting at Subscriber’s direction or pursuant to any understanding with Subscriber (including Subscriber’s controlled affiliates), directly or indirectly, offer, sell, pledge, contract to sell, sell any option in, or engage in hedging activities or execute any “short sales” (as defined in Rule 200 of Regulation SHO under the Exchange Act) with respect to, any Subscribed Shares or any securities of the Issuer or any instrument exchangeable for or convertible into any Subscribed Shares or any securities of the Issuer until the Acquisition Closing (or such earlier termination of this Subscription Agreement in accordance with its terms). Notwithstanding the foregoing, (i) nothing herein shall prohibit any entities under common management or that share an investment advisor with Subscriber (including Subscriber’s controlled affiliates and/or affiliates) from entering into any Short Sales; (ii) in the case of a Subscriber that is a multimanaged investment vehicle whereby separate portfolio managers manage separate portions of such Subscriber’s assets, this Section 6.2 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 covered by this Subscription Agreement. For the avoidance of doubt, this Section 6.2 shall not apply to (i) any sale (including the exercise of any redemption right) of securities of the Issuer (A) held by Subscriber, its controlled affiliates or any person or entity acting on behalf of Subscriber or any of its controlled affiliates prior to

the execution of this Subscription Agreement or (B) purchased by Subscriber, its controlled affiliates or any person or entity acting on behalf of Subscriber or any of its controlled affiliates in an open market transaction after the execution of this Subscription Agreement or (ii) ordinary course, non-speculative hedging transactions. The Issuer acknowledges and agrees that, notwithstanding anything herein to the contrary, the Subscribed Shares 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 shall not be required to provide the Issuer with any notice thereof; provided, however, that neither the Issuer 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 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 Issuer in all respects.

6.3.   Notices. Any notice or communication required or permitted hereunder shall be in writing and either delivered personally, emailed or sent by overnight mail via a reputable overnight carrier, or sent by certified or registered mail, postage prepaid, and shall be deemed to be given and received (i) when so delivered personally, (ii) when sent, with no mail undeliverable or other rejection notice, if sent by email, or (iii) three (3) Business Days after the date of mailing to the address below or to such other address or addresses as such person may hereafter designate by notice given hereunder:

6.4.   Entire Agreement. 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, including any commitment letter entered into relating to the subject matter hereof.

6.5.   Modifications and Amendments. 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 and also signed by Oculis, provided that Section 2, Section 4.4.2, Section 4.4.5, Section 5, Section 6.1.1, Section 6.1.2, Section 6.5, Section 6.7, Section 6.8, Section 6.9, Section 6.11, Section 6.13, Section 6.14, Section 8 and Section 9 of this Subscription Agreement may not be amended, modified or waived without the prior written consent of the Placement Agent.

6.6.   Assignment. This Subscription Agreement and any rights, interests or obligations that may accrue to the Issuer and Subscriber hereunder (other than the Subscribed Shares acquired hereunder and the rights set forth in Section 4) may be transferred or assigned without the prior written consent of Subscriber, Issuer and Oculis, as applicable; provided that prior to such assignment any such assignee(s) agrees in writing to be bound by the terms hereof, and upon such assignment by a Subscriber, the assignee(s) shall become Subscriber hereunder and have the rights and obligations and be deemed to make the representations and warranties of Subscriber provided for herein to the extent of such assignment; provided further that, no assignment shall relieve the assigning party of any of its obligations hereunder, including any assignment to any fund or account managed by the same investment manager as Subscriber.

6.7.   Benefit. 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 the agreements, representations, warranties, covenants and acknowledgments contained herein shall be deemed to be made by, and be binding upon, such heirs, executors, administrators, successors, legal representatives and permitted assigns. This Subscription Agreement shall not confer rights or remedies upon any person other than the parties hereto and their respective successors and assigns, except that the Placement Agent shall be third-party beneficiaries to the representations, warranties, understandings and undertakings made by the Issuer and Subscriber in this Subscription Agreement and as provided in Section 4.4.2, Section 6.5, Section 6.14 and Section 9 and Oculis shall be a third-party beneficiary with respect to the entirety of this Subscription Agreement and as provided in Section 4.4.

6.8.   Governing Law. 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 giving effect to the principles of conflicts of law thereof.

6.9.   Consent to Jurisdiction; Waiver of Jury Trial. Each of the parties irrevocably consents to the exclusive jurisdiction and venue of the Court of Chancery of the State of Delaware, provided that if subject matter jurisdiction over the matter that is the subject of the legal proceeding is vested exclusively in the U.S. federal courts, such legal proceeding shall be heard in the U.S. District Court for the District of Delaware (together with the Court of Chancery

of the State of Delaware, “Chosen Courts”), in connection with any matter based upon or arising out of this Subscription Agreement. Each party hereby waives, and shall not assert as a defense in any legal dispute, that (i) such person is not personally subject to the jurisdiction of the Chosen Courts for any reason, (ii) such legal proceeding may not be brought or is not maintainable in the Chosen Courts, (iii) such person’s property is exempt or immune from execution, (iv) such legal proceeding is brought in an inconvenient forum or (v) the venue of such legal proceeding is improper. Each party hereby consents to service of process in any such proceeding in any manner permitted by Delaware law, further consents to service of process by nationally recognized overnight courier service guaranteeing overnight delivery, or by registered or certified mail, return receipt requested, at its address specified pursuant to Section ‎6.3 and waives and covenants not to assert or plead any objection which they might otherwise have to such manner of service of process. Notwithstanding the foregoing in this Section ‎6.9, a party may commence any action, claim, cause of action or suit in a court other than the Chosen Courts solely for the purpose of enforcing an order or judgment issued by the Chosen Courts. TO THE EXTENT NOT PROHIBITED BY APPLICABLE LAW WHICH CANNOT BE WAIVED, EACH OF THE PARTIES WAIVES ANY RIGHT TO TRIAL BY JURY ON ANY CLAIMS OR COUNTERCLAIMS ASSERTED IN ANY LEGAL DISPUTE RELATING TO THIS SUBSCRIPTION AGREEMENT WHETHER NOW EXISTING OR HEREAFTER ARISING. IF THE SUBJECT MATTER OF ANY SUCH LEGAL DISPUTE IS ONE IN WHICH THE WAIVER OF JURY TRIAL IS PROHIBITED, NO PARTY SHALL ASSERT IN SUCH LEGAL DISPUTE A NONCOMPULSORY COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS SUBSCRIPTION AGREEMENT. FURTHERMORE, NO PARTY SHALL SEEK TO CONSOLIDATE ANY SUCH LEGAL DISPUTE WITH A SEPARATE ACTION OR OTHER LEGAL PROCEEDING IN WHICH A JURY TRIAL CANNOT BE WAIVED.

6.10.   Severability. 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.

6.11.   No Waiver of Rights, Powers and Remedies. 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.

6.12.   Remedies.

6.12.1.   The parties agree that irreparable damage would occur if this Subscription Agreement is not performed or the Closing is not consummated in accordance with its specific terms or is otherwise breached and that money damages or other legal remedies would not be an adequate remedy for any such damage. It is accordingly agreed that the parties hereto shall be entitled to equitable relief, including in the form of an injunction or injunctions, to prevent breaches or threatened breaches of this Subscription Agreement and to enforce specifically the terms and provisions of this Subscription Agreement in an appropriate court of competent jurisdiction as set forth in Section ‎6.9, this being in addition to any other remedy to which any party is entitled at law or in equity, including money damages. The right to specific enforcement shall include the right of the parties hereto to cause the other parties hereto to cause the transactions contemplated hereby to be consummated on the terms and subject to the conditions and limitations set forth in this Subscription Agreement. The parties hereto further agree (i) to waive any requirement for the security or posting of any bond in connection with any such equitable remedy, (ii) not to assert that a remedy of specific enforcement pursuant to this Section ‎6.12 is unenforceable, invalid, contrary to applicable law or inequitable for any reason and (iii) to waive any defenses in any action for specific performance, including the defense that a remedy at law would be adequate.

6.12.2.   The parties acknowledge and agree that this Section ‎6.12 is an integral part of the transactions contemplated hereby and without that right, the parties hereto would not have entered into this Subscription Agreement.

6.13.   Survival of Representations and Warranties and Covenants. All representations and warranties made by the parties hereto, and all covenants and other agreements of the parties hereto, in this Subscription Agreement shall survive the Closing.

6.14.   No Liability. Subscriber agrees that the Placement Agent shall not 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 hereunder. On behalf of Subscriber and its affiliates, Subscriber releases the Placement Agent in respect of any Losses related to the Transactions and the purchase and sale of the Subscribed Shares hereunder. Subscriber agrees not to commence any litigation or bring any claim against the Placement Agent in any court or any 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 hereunder. This undertaking is given freely and after obtaining independent legal advice, except for such party’s own gross negligence, willful misconduct or bad faith.

6.15.   Headings and Captions. The headings and captions of the various subdivisions of this Subscription Agreement are for convenience of reference only and shall in no way modify or affect the meaning or construction of any of the terms or provisions hereof.

6.16.   Counterparts. This Subscription Agreement may be executed in one or more counterparts, all of which when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other parties, it being understood that the parties need not sign the same

counterpart. In the event that any signature is delivered by facsimile transmission or any other form of electronic delivery, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such signature page were an original thereof.

6.17.   Construction. 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 Subscription Agreement,” “herein,” “hereof,” “hereby,” “hereunder,” and words of similar import refer to this Subscription 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. All references in this Subscription Agreement to numbers of shares, per share amounts and purchase prices shall be appropriately adjusted to reflect any stock split, stock dividend, stock combination, recapitalization or the like occurring after the date hereof.

6.18.   Mutual Drafting. This Subscription Agreement is the joint product of the parties hereto and each provision hereof has been subject to the mutual consultation, negotiation and agreement of the parties and shall not be construed for or against any party hereto.

7.   Cleansing Statement; Disclosure.

7.1.   The Issuer shall, or shall cause New Parent to, on the first (1st) Business Day immediately following the date of this Subscription Agreement, issue one or more press releases or file with the Commission a Current Report on Form 8-K (collectively, the “Disclosure Document”) disclosing all material terms of the transactions contemplated hereby and by the Other Subscription Agreements and the Transactions and any other material nonpublic information that the Issuer or its officers, directors, employees or agents has provided to Subscriber prior to the filing of the Disclosure Document. Upon the issuance of the Disclosure Document, to the actual knowledge of the Issuer, Subscriber shall not be in possession of any material, non-public information received from the Issuer or any of its 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 Issuer, the Placement Agent or any of its affiliates, relating to the transactions contemplated by this Subscription Agreement.

7.2.   Notwithstanding anything in this Subscription Agreement to the contrary, the Issuer shall not (and shall cause its officers, directors, employees and agents not to) publicly disclose the name of Subscriber or any affiliate or investment adviser of Subscriber, or include the name of Subscriber or any affiliate or investment adviser of Subscriber without the prior written consent (including by e-mail) of Subscriber (i) in any press release or marketing materials, or (ii) in any filing with the Commission or any regulatory agency or trading market,

except as required by the federal securities laws, rules or regulations and to the extent such disclosure is required by other laws, rules or regulations, at the request of the staff of the Commission or regulatory agency or under regulations of Nasdaq, in which case the Issuer shall provide Subscriber with prior written notice (including by e-mail) of such permitted disclosure, and shall reasonably consult with Subscriber regarding such disclosure.

8.   Trust Account Waiver. In addition to the waiver of the Issuer pursuant to Section 12.01 of the Business Combination Agreement, and notwithstanding anything to the contrary set forth herein, each of the Issuer and Subscriber acknowledges that the Issuer has established a trust account containing the proceeds of its initial public offering and from certain private placements (collectively, with interest accrued from time to time thereon, the “Trust Account”). Each of the Issuer and Subscriber agrees that (i) it has no right, title, interest or claim of any kind in or to any monies held in the Trust Account, and (ii) it shall have no right of set-off or any right, title, interest or claim of any kind (“Claim”) to, or to any monies in, the Trust Account, in each case in connection with this Subscription Agreement, and hereby irrevocably waives any Claim to, or to any monies in, the Trust Account that it may have in connection with this Subscription Agreement; provided, however, that nothing in this Section ‎8 shall (x) serve to limit or prohibit Subscriber’s right to pursue a claim against the Issuer for legal relief against assets held outside the Trust Account, for specific performance or other equitable relief, (y) serve to limit or prohibit any claims that Subscriber may have in the future against the Issuer’s assets or funds that are not held in the Trust Account (including any funds that have been released from the Trust Account and any assets that have been purchased or acquired with any such funds) or (z) be deemed to limit Subscriber’s right, title, interest or claim to the Trust Account by virtue of such Subscriber’s record or beneficial ownership of securities of the Issuer, including, but not limited to, any redemption right with respect to any such securities of the Issuer. In the event Subscriber has any Claim against the Issuer under this Subscription Agreement, Subscriber shall pursue such Claim solely against the Issuer and its assets outside the Trust Account and not against the property or any monies in the Trust Account. Subscriber agrees and acknowledges that such waiver is material to this Subscription Agreement and has been specifically relied upon by the Issuer to induce the Issuer to enter into this Subscription Agreement and Subscriber further intends and understands such waiver to be valid, binding and enforceable under applicable law.
Notwithstanding the foregoing, in no event shall the terms of this Section 8 apply to any money or other assets held outside the Trust Account.

9.   Non-Reliance. Subscriber acknowledges that it is not relying upon, and has not relied upon, any statement, representation or warranty made by any person, firm or corporation, (including, without limitation, Oculis, any Placement Agent, any of their respective affiliates or any of their respective control persons, officers, directors or employees), other than the representations and warranties of the Issuer expressly set forth in this Subscription Agreement, in making its investment or decision to invest in the Issuer. Subscriber agrees that neither (i) an Other Subscriber pursuant to this Subscription Agreement or any other agreement related to the private placement of shares of the Issuer’s capital stock (including the controlling persons, officers, directors, partners, agents or employees of any such Subscriber) nor (ii) Oculis, the Placement Agent, its affiliates or any of its control persons, officers, directors, partners, agents or employees shall be liable to any Other Subscriber pursuant to this Subscription Agreement or any other agreement related to the private placement of shares of the Issuer’s capital stock for

any action heretofore or hereafter taken or omitted to be taken by any of them in connection with the purchase of the Subscribed Shares hereunder.

10.   Rule 144. From and after such time as the benefits of Rule 144 promulgated under the Securities Act or any other similar rule or regulation of the Commission that may allow Subscriber to sell securities of the Issuer to the public without registration are available to holders of the Issuer’s shares of common stock and for so long as Subscriber holds the Subscribed Shares, the Issuer agrees to, and shall cause New Parent to agree to:

10.1.   make and keep public information available, as those terms are understood and defined in Rule 144; and

10.2.   file with the Commission in a timely manner all reports and other documents required of the Issuer under the Securities Act and the Exchange Act so long as the Issuer remains subject to such requirements and the filing of such reports and other documents is required for the applicable provisions of Rule 144; and

10.3.   furnish to Subscriber so long as it owns Subscribed Shares, as promptly as practicable upon request, (x) a written statement by the Issuer or New Parent, as applicable, if true, that it has complied with the reporting requirements of Rule 144, the Securities Act and the Exchange Act, and (y) such other information as may be reasonably requested to permit Subscriber to sell such securities pursuant to Rule 144 without registration.

The Issuer shall, or shall cause New Parent to, if requested by Subscriber, use commercially reasonable efforts to (i) cause the removal of any restrictive legend related to compliance with the federal securities laws set forth on the Subscribed Shares, (ii) cause its legal counsel to deliver an opinion, if necessary, to the transfer agent in connection with the instruction under subclause (i) to the effect that removal of such legends in such circumstances may be effected in compliance under the Securities Act, and (iii) issue Subscribed Shares without any such legend in certificated or book-entry form or by electronic delivery through The Depository Trust Company, at Subscriber’s option, within two (2) Business Days of such request, if (A) such Subscribed Shares may be sold by Subscriber without restriction under Rule 144, including without limitation, any volume and manner of sale restrictions, or (B) Subscriber has sold or transferred Subscribed Shares pursuant to the Registration Statement or in compliance with Rule 144. The Issuer’s or New Parent’s obligation to remove legends under this paragraph may be conditioned upon Subscriber providing such representations and documentation (including broker representation letters) as are reasonably necessary and customarily required in connection with the removal of restrictive legends related to compliance with the federal securities laws. Subscriber agrees to disclose its beneficial ownership, as determined in accordance with Rule 13d-3 of the Exchange Act, of Ordinary Shares to the Issuer (or its successor) upon reasonable request to assist the Issuer or New Parent, as applicable, in making the determination described above. Notwithstanding the foregoing, the Issuer will not be required to deliver any such opinion, authorization, certificate, or direction if it reasonably believes that removal of the legend could result in or facilitate transfers of securities in violation of applicable law.
