Item 1.01 Entry Into a Material Definitive Agreement.

Business Combination Agreement

On September 29, 2022, Summit Healthcare Acquisition Corp., an exempted company limited by shares incorporated under the laws of the Cayman Islands (“Summit”) entered into a Business Combination Agreement (the “Business Combination Agreement”) with YishengBio Co., Ltd., an exempted company limited by shares incorporated under the laws of the Cayman Islands (to be renamed as YS Biopharma Co., Ltd, herein referred to as “YS Biopharma”), Oceanview Bioscience Acquisition Co., Ltd., an exempted company limited by shares incorporated under the laws of the Cayman Islands and a direct wholly-owned subsidiary of YS Biopharma (“Merger Sub I”) and Hudson Biomedical Group Co., Ltd., an exempted company limited by shares incorporated under the laws of the Cayman Islands and a direct wholly-owned subsidiary of YS Biopharma (“Merger Sub II,” and together with Merger Sub I, “Merger Subs”). Capitalized terms in this Item 1.01 not otherwise defined shall have the meanings ascribed to them in the Business Combination Agreement.

The Business Combination Agreement and the Transactions (as defined below) were unanimously approved by the boards of directors of Summit and YS Biopharma and were approved by the shareholders of YS Biopharma. The Transactions are expected to be consummated after obtaining the required approval by the shareholders of Summit and the satisfaction of certain other customary closing conditions.

The Business Combination

The Business Combination Agreement provides for (i) the merger of Merger Sub I with and into Summit (the “First Merger”), with Summit surviving the First Merger as the surviving entity (the “Surviving Entity”) and becoming a wholly-owned subsidiary of YS Biopharma, and (ii) the merger of the Surviving Entity with and into Merger Sub II (the “Second Merger,” and together with the First Merger, the “Mergers,” together with other transactions contemplated by the Business Combination Agreement, the “Transactions”), with Merger Sub II surviving the Second Merger as the surviving company (the “Surviving Company”) and remaining as the wholly-owned subsidiary of YS Biopharma.

Subject to, and in accordance with the terms and conditions set forth in the Business Combination Agreement, immediately prior to the effective time of the First Merger (the “First Merger Effective Time”), (i) each preferred share of YS Biopharma with par value of US$0.000005 will be converted into one ordinary share of YS Biopharma with par value of US$0.000005; (ii) after the conversion of all preferred shares into ordinary shares, each four of the ordinary shares of YS Biopharma with par value of US$0.000005 will be consolidated into one ordinary share of YS Biopharma with par value of US$0.00002, and each four of the options to acquire ordinary shares of YS Biopharma will be consolidated into one option to acquire ordinary share of YS Biopharma, subject to rounding up to the nearest whole number of shares; and (iii) the second amended and restated memorandum and articles of association of YS Biopharma shall be adopted and become effective. Items (i) through (iii) are herein referred to as the “YS Biopharma Capital Restructuring.”

Subject to, and in accordance with the terms and conditions set forth in the Business Combination Agreement, following completion of the YS Biopharma Capital Restructuring and immediately prior to the First Merger Effective Time, (i) each of Summit’s units (“Units”) (each consisting of one Class A ordinary share of Summit, par value US$0.0001 per share (“Summit Class A Share”) and one-half of one redeemable warrant of Summit, with each whole warrant exercisable for one Summit Class A Share (“Summit Warrant”)) issued and outstanding immediately prior to the First Merger Effective Time shall be automatically detached and the holder thereof shall be deemed to hold one Summit Class A Share and one-half of one Summit Warrant (the “Unit Separation”); (ii) each Summit Class A Share (including Summit Class A Shares held by Summit’s public shareholders as a result of the Unit Separation and Summit Class A Shares to be issued pursuant to the Forward Purchase Subscriptions, but excluding any treasury Summit Shares, redeeming Summit Shares and dissenting Summit Shares) issued and outstanding immediately prior to the First Merger Effective Time shall automatically be cancelled and cease to exist, in exchange for the right to receive such fraction of newly issued ordinary shares of YS Biopharma with par value of US$0.00002 after the YS Biopharma Capital Restructuring (“YS Biopharma Ordinary Shares”) that is equal to the SPAC Class A Exchange Ratio (as described below), without interest; (iii) an aggregate of 1,446,525 Class B ordinary shares of Summit, par value US$0.0001 per share (“Summit Class B Shares,” together with Summit Class A Shares, “Summit Shares”) held by Summit Healthcare Acquisition Sponsor LLC, a Cayman Islands limited liability company (“Sponsor”) will be surrendered for nil consideration, and after such surrender, each of the remaining Summit Class B Shares held by Sponsor and the independent directors of Summit issued and outstanding immediately prior to the First Merger Effective Time shall automatically be cancelled and cease to exist, in exchange for the right to receive one newly issued YS Biopharma Ordinary Share; (iv) each Summit Class B Share held by a Forward Purchase Investor and its permitted transferees issued and outstanding immediately prior to the First Merger Effective Time shall automatically be cancelled and cease to exist, in exchange for the right to receive (a) such fraction of newly issued YS Biopharma Ordinary Shares that is equal to the SPAC Class A Exchange Ratio, without interest, if and only if such Forward Purchase Investor has fully delivered its portion of the Forward Purchase Investment Amount as required under the applicable Forward Purchase Agreement and, failing that, (b) one newly issued YS Biopharma Ordinary Share; and (v) each whole Summit Warrant outstanding immediately prior to the First Merger Effective Time shall cease to be a warrant with respect to Summit Shares and be assumed by YS Biopharma and converted into a warrant of YS Biopharma to purchase one YS Biopharma Ordinary Share (the “YS Biopharma Warrants”), subject to substantially the same terms and conditions prior to the First Merger Effective Time. No fractional shares or warrants will be issued in the foregoing process, and all such shares or warrants would be rounded down to the nearest whole number of shares or warrants.

The SPAC Class A Exchange Ratio will be calculated based on the number of redeeming and non-redeeming Summit Shares. As a result of changes to the SPAC Class A Exchange Ratio, up to an aggregate of 2,732,325 YS Biopharma Ordinary Shares, including 1,446,525 YS Biopharma Ordinary Shares to be contributed by the Sponsor through a share surrender immediately prior to the First Merger Effective Time and up to 1,285,800 new YS Biopharma Ordinary Shares, will be provided to non-redeeming Summit shareholders and the Forward Purchase Investors, which is expected to enhance the value of the YS Biopharma Ordinary Shares to be issued to these investors.

In addition, upon the consummation of the First Merger, (i) if there are any Summit Shares that are owned by Summit as treasury shares or any Summit Shares owned by any direct or indirect subsidiary of Summit immediately prior to the First Merger Effective Time, such Summit Shares shall be canceled and shall cease to exist without any conversion thereof or payment or other consideration therefor; (ii) each Redeeming SPAC Share issued and outstanding immediately prior to the First Merger Effective Time shall be cancelled and cease to exist and shall thereafter represent only the right to be paid a pro rata share of the SPAC Shareholder Redemption Amount in accordance with Summit’s amended and restated memorandum and articles of association; and (iii) each Dissenting SPAC Share issued and outstanding immediately prior to the First Merger Effective Time held by a Dissenting SPAC Shareholder shall be cancelled and cease to exist and shall thereafter represent only the right to be paid the fair value of such Dissenting SPAC Share and such other rights as are granted by the Cayman Act.

Representations and Warranties

The Business Combination Agreement contains representations and warranties of each of the parties thereto that are customary for transactions of this type, many of which are qualified by materiality. The representations and warranties of the respective parties to the Business Combination Agreement will not survive the closing of the Mergers (the “Closing”).

The foregoing description of the Business Combination Agreement and the Transactions does not purport to be complete and is qualified in its entirety by the full text of the Business Combination Agreement and related agreements.

The Business Combination Agreement contains representations, warranties and covenants that the respective parties made to each other as of the date of such agreement or other specific dates set forth thereunder. The assertions embodied in those representations, warranties and covenants were made for purposes of the contract among the respective parties and are subject to important qualifications and limitations agreed to by the parties in connection with negotiating such agreement. The Business Combination Agreement has been included as Exhibit 2.1 to this Current Report on Form 8-K (this “Current Report”) to provide information regarding its terms. It is not intended to provide any other factual information about Summit, YS Biopharma, or any other party to the Business Combination Agreement or any related agreement. In particular, the representations, warranties, covenants and agreements contained in the Business Combination Agreement, which were made only for purposes of such agreement and as of specific dates, were solely for the benefit of the parties to the Business Combination Agreement, are subject to limitations agreed upon by the contracting parties (including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties to the Business Combination Agreement instead of establishing these matters as facts) and are subject to standards of materiality applicable to the contracting parties that may differ from those applicable to investors and security holders and reports and documents filed with the U.S. Securities and Exchange Commission (the “SEC”). Investors and security holders are not third-party beneficiaries under the Business Combination Agreement and should not rely on the representations, warranties, covenants and agreements, or any descriptions thereof, as characterizations of the actual state of facts or condition of any party to the Business Combination Agreement. In addition, the representations, warranties, covenants and agreements and other terms of the Business Combination Agreement may be subject to subsequent waiver or modification. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Business Combination Agreement, which subsequent information may or may not be fully reflected in Summit’s public disclosures.

Related Agreements

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

Shareholder Support Agreement

Concurrently with the execution of the Business Combination Agreement, YS Biopharma and Summit entered into a Shareholder Support Agreement and Deed (the “Shareholder Support Agreement”) with certain YS Biopharma shareholders (the “YSB Shareholders”) and certain Summit shareholders (the “SPAC Shareholders,” and together with the YSB Shareholders, the “Supporting Shareholders”) with respect to the Transactions and post-Closing rights and obligations of shareholders of YS Biopharma. The Shareholder Support Agreement provides that, among other things,

Shareholder Support. (i) the Supporting Shareholders will appear at shareholders meetings of YS Biopharma (or Summit, as applicable) and vote in favor of, consent to or approve the Business Combination Agreement and the transactions contemplated by the Business Combination Agreement, whether at a shareholder meeting of YS Biopharma (or Summit, as applicable) or by written consent, except that no YSB Shareholder shall be obliged to vote in favor of any future amendment, modification or supplement to the Business Combination Agreement or any other Transaction Document; (ii) the Supporting Shareholders will vote against (or act by written consent against) any alternative proposals or actions that would impede, interfere with, delay, postpone or adversely affect the transactions contemplated by the Business Combination Agreement; (iii) the YSB Shareholders agree not to exercise any redemption rights with respect to the shares of YS Biopharma owned by them from the date of the Business Combination Agreement until the Shareholder Support Agreement is terminated in accordance with its terms, subject to certain exceptions set forth therein; (iv) the Sponsor will surrender 1,446,525 Summit Class B Shares for nil consideration immediately prior to the First Merger Effective Time and exchange all of the remaining Summit Shares held by it into YS Biopharma Ordinary Shares on a one-for-one basis at the First Merger Effective Time; and (v) the Sponsor agrees to reimburse Summit or YS Biopharma, at the Closing, certain transaction and operating expenses of Summit if such expenses exceed the amounts agreed by Summit and YS Biopharma.

Shareholders Rights. (i) the letter agreement between Summit, Sponsor and certain other parties thereto, dated as of June 8, 2021, and all the registration and shareholder rights thereunder, will be terminated effective at the First Merger Effective Time; and (ii) YS Biopharma and the YSB Shareholders agree to amend the shareholders agreement of YS Biopharma (the “YS Biopharma Shareholders Agreement”) and terminate all the special shareholder rights and obligations thereunder, effective at the First Merger Effective Time, except for the following rights and transfer restrictions:

(i) Registration Rights. The Supporting Shareholders, together with any other shareholder of YS Biopharma who currently is or subsequently becomes a party to the YS Biopharma Shareholders Agreement, are entitled to customary demand and piggyback registration rights. YS Biopharma also agrees to file a registration statement on Form F-1 within 20 days after the Closing (or 60 days if additional financial information is required) to register the registrable securities pursuant to the YS Biopharma Shareholders Agreement.

(ii) Lock-Up Restrictions. Summit and YS Biopharma agree to cause the Sponsor and the independent directors of Summit (together with the Sponsor, the “SPAC Insiders”) and all pre-Closing shareholders of YS Biopharma (together with the SPAC Insiders, the “YS Biopharma Lock-Up Shareholders”) to be subject to certain lock-up restrictions as provided therein, effective as of the First Merger Effective Time, pursuant to which, any YS Biopharma Ordinary Shares held by such YS Biopharma Lock-Up Shareholder immediately after the First Merger Effective Time (such YS Biopharma Ordinary Shares, collectively, the “YS Biopharma Lock-Up Shares”) shall not be transferred during the applicable lock-up period, subject to customary exceptions. For each YS Biopharma Lock-Up Shareholder who is not a SPAC Insider, the applicable lock-up period will be 180 days from and after the First Merger Effective Time. For each YS Biopharma Lock-Up Shareholder who is a SPAC Insider, the applicable lock-up period will be twelve months from and after the First Merger Effective Time. The lock-up requirements will cease to apply after the date on which the closing price of the YS Biopharma Ordinary Shares equals or exceeds $12.00 per share for any 20 trading days within any 30 trading day period commencing at least 150 days after the First Merger Effective Time. YS Biopharma may release, (i) in its sole discretion, up to 3,000,000 YS Biopharma Lock-Up Shares and (ii) with prior written consent from Summit and the Sponsor, an additional number of YS Biopharma Lock-Up Shares to the extent necessary to satisfy the minimum public float requirement as required for obtaining Nasdaq’s listing approval, provided that a release pursuant to sub-clauses (i) and (ii) shall apply on a pro rata basis to all YS Biopharma Lock-Up Shares held by YS Biopharma Lock-Up Shareholders who are holders of preferred shares of YS Biopharma (and ordinary shares issued upon conversion thereof) immediately prior to the First Merger Effective Time.

(iii) Director Appointment Rights. The Sponsor will have the right to appoint two directors on the board of directors of YS Biopharma so long as the Sponsor beneficially owns not less than 1% of all the issued and outstanding shares of YS Biopharma after the Closing.

The foregoing description of the Shareholder Support Agreement is qualified in its entirety by reference to the full text of such agreement filed as Exhibit 10.1 to this Current Report and incorporated by reference herein.

Warrant Assignment Agreement

Concurrently with the execution of the Business Combination Agreement, YS Biopharma, Summit and Continental Stock Transfer & Trust Company, the warrant agent to Summit (the “Warrant Agent”), entered into a warrant assignment agreement (the “Warrant Assignment Agreement”) to amend such warrant agreement (the “Warrant Agreement”), dated June 8, 2021, by and between Summit and the Warrant Agent, pursuant to which Summit assigns and delegates to YS Biopharma all of its rights, interests, and obligations in and under the Warrant Agreement, effective as of the First Merger Effective Time.

The foregoing description of the Warrant Assignment Agreement is qualified in its entirety by reference to the full text of such agreement filed as Exhibit 10.2 to this Current Report and incorporated by reference herein.

Forward Purchase Agreements

Prior to Summit’s initial public offering, Summit entered into forward purchase agreements (collectively, the “Forward Purchase Agreements”) with each of Snow Lake Capital (HK) Limited and the Valliance Fund (collectively, the “Forward Purchase Investors”). The Forward Purchase Agreements provide for the purchase by the Forward Purchase Investors of an aggregate of 3,000,000 Summit Class A Shares, plus an aggregate of 750,000 redeemable warrants to purchase Summit Class A Shares at $11.50 per share, for an aggregate purchase price of $30,000,000 in a private placement to close concurrently with the closing of Summit’s initial business combination, which will be the consummation of the Transactions. The Forward Purchase Investors’ subscription obligations under the Forward Purchase Agreements do not depend on whether any Summit Class A Shares are redeemed by Summit’s public shareholders. Proceeds received from the Forward Purchase Investors under the Forward Purchase Agreements will count towards the Available Closing Cash Amount, which is required to be not less than $30,000,000 under the Business Combination Agreement. The Forward Purchase Investors have also agreed to vote all Summit Shares held by them in favor of Summit’s initial business combination if Summit seeks shareholder approval of such transaction.

The foregoing description of the Forward Purchase Agreements is qualified in its entirety by reference to the full text of such agreements filed as Exhibit 10.6 and Exhibit 10.7 to the Current Report on Form 8-K filed by Summit on June 14, 2021, and incorporated by reference herein.

Promissory Note

On September 29, 2022, Summit issued an unsecured, interest-free promissory note to the Sponsor (the “Sponsor Convertible Note”) pursuant to which Summit may borrow up to US$1,500,000 from the Sponsor for costs and expenses reasonably related to Summit’s working capital needs prior to the consummation of the Business Combination. All unpaid principal under the Sponsor Convertible Note will become due and payable in full on the date on which Summit consummates the Business Combination (such date, the “Maturity Date”), unless earlier accelerated upon the occurrence of an Event of Default (as defined in the Sponsor Convertible Note). The Sponsor will have the option, at any time on or prior to the Maturity Date, to convert any amounts outstanding under the Sponsor Convertible Note, up to US $1,500,000 in the aggregate, into warrants to purchase Summit Class A Shares, at a conversion price of $1.00 per warrant, with each warrant entitling the holder to purchase one Summit Class A Share at a price of $11.50 per share, subject to the same adjustments applicable to the private placement warrants sold concurrently with Summit’s initial public offering. As previously disclosed, Wei Fu, Summit’s Honorary Chairman and Senior Advisor, Bo Tan, Summit’s Chief Executive Officer, Co-Chief Investment Officer and Director and Ken Poon, Summit’s President, Co-Chief Investment Officer and Director, are managers of the Sponsor and have voting and investment discretion with respect to the Summit Shares held of record by the Sponsor.

The foregoing description of the Sponsor Convertible Note is qualified in its entirety by reference to the full text of such agreement filed as Exhibit 2.2 to this Current Report and incorporated by reference herein.

Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

Cautionary Statement Regarding Forward-Looking Statements

This Current Report includes “forward-looking statements” within the meaning of the “safe harbor” provisions of the United States Private Securities Litigation Reform Act of 1995. Forward-looking statements may be identified by the use of words such as “estimate,” “plan,” “project,” “forecast,” “intend,” “will,” “expect,” “anticipate,” “believe,” “seek,” “target” or other similar expressions that predict or indicate future events or trends or that are not statements of historical matters. These forward-looking statements also include, but are not limited to, statements regarding projections, estimates and forecasts of revenue and other financial and performance metrics, anticipated milestones with respect to the clinical and pre-clinical programs of YS Biopharma, projections of market opportunity and expectations, the estimated implied enterprise value of the combined company, YS Biopharma’s ability to scale and grow its business, the advantages and expected growth of the combined company, the combined company’s ability to source and retain talent, the cash position of the combined company following closing of the Transactions, Summit’s and YS Biopharma’s ability to consummate the proposed Transaction, and expectations related to the terms and timing of the Transactions, as applicable. These statements are based on various assumptions, whether or not identified in this Current Report, and on the current expectations of Summit’s and YS Biopharma’s management and are not predictions of actual performance.

These statements involve risks, uncertainties and other factors that may cause actual results, levels of activity, performance or achievements to be materially different from those expressed or implied by these forward-looking statements. Although each of Summit and YS Biopharma believes that it has a reasonable basis for each forward-looking statement contained in this Current Report, each of Summit and YS Biopharma caution you that these statements are based on a combination of facts and factors currently known and projections of the future, which are inherently uncertain. In addition, there will be risks and uncertainties described in the proxy statement/prospectus on Form F-4 relating to the proposed transaction, which is expected to be filed by YS Biopharma with the SEC and other documents filed by YS Biopharma or Summit from time to time with the SEC. These filings may identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Neither Summit nor YS Biopharma can assure you that the forward-looking statements in this Current Report will prove to be accurate. These forward-looking statements are subject to a number of risks and uncertainties, including, among others, the ability to complete the Mergers due to the failure to obtain approval from Summit’s shareholders or satisfy other closing conditions in the Business Combination Agreement, the occurrence of any event that could give rise to the termination of the Business Combination Agreement, the ability to recognize the anticipated benefits of the Mergers, the amount of redemption requests made by Summit’s public shareholders, costs related to the transaction, the impact of the global COVID-19 pandemic, the risk that the transaction disrupts current plans and operations as a result of the announcement and consummation of the transaction, the outcome of any potential litigation, government or regulatory proceedings and other risks and uncertainties, including those to be included under the heading “Risk Factors” in the Registration Statement to be filed by YS Biopharma with the SEC and those included under the heading “Risk Factors” in the annual report on Form 10-K for year ended December 31, 2021 of Summit and in its subsequent quarterly reports on Form 10-Q and other filings with the SEC. There may be additional risks that neither Summit nor YS Biopharma presently know or that Summit and YS Biopharma currently believe are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. In light of the significant uncertainties in these forward-looking statements, nothing in this Current Report should be regarded as a representation by any person that the forward-looking statements set forth herein will be achieved or that any of the contemplated results of such forward-looking statements will be achieved. The forward-looking statements in this Current Report represent the views of Summit and YS Biopharma as of the date of this Current Report. Subsequent events and developments may cause those views to change.

(h)            Effect of the Mergers on Issued Securities of SPAC, Merger Sub I and Merger Sub II. On the terms and subject to the conditions set forth herein, by virtue of the Mergers and without any further action on the part of any Party or any other Person, the following shall occur:

(i)            SPAC Units. Immediately prior to the First Merger Effective Time, each SPAC Unit issued and outstanding immediately prior to the First Merger Effective Time shall be automatically detached and the holder thereof shall be deemed to hold one SPAC Class A Ordinary Share and one-half of a SPAC Warrant in accordance with the terms of the applicable SPAC Unit (the “Unit Separation”), provided that no fractional SPAC Warrants will be issued in connection with the Unit Separation such that if a holder of SPAC Units would be entitled to receive a fractional SPAC Warrant upon the Unit Separation, the number of SPAC Warrants to be issued to such holder upon the Unit Separation shall be rounded down to the nearest whole number of SPAC Warrants. The underlying SPAC Securities held or deemed to be held following the Unit Separation shall be converted in accordance with the applicable terms of this Section 2.2(h).

(ii)          SPAC Ordinary Shares. Immediately following the separation of each SPAC Unit in accordance with Section 2.2(h)(i) and the Company Capital Restructuring,

(1)            each SPAC Class A Ordinary Share (which, for the avoidance of doubt, includes (x) the SPAC Class A Ordinary Shares held by the public shareholders of SPAC as a result of the Unit Separation and (y) the SPAC Class A Ordinary Shares issued pursuant to the Forward Purchase Subscriptions) issued and outstanding immediately prior to the First Merger Effective Time (other than any SPAC Shares referred to in Section 2.2(h)(iv) and Section 2.2(h)(ii)(3), Redeeming SPAC Shares and Dissenting SPAC Shares) shall automatically be cancelled and cease to exist in exchange for the right to receive, upon delivery of the applicable Letter of Transmittal (if any) in accordance with Section 2.4, such fraction of a newly issued Company Ordinary Share that is equal to the SPAC Class A Exchange Ratio, without interest, subject to rounding pursuant to Section 2.4(e);

(2)            (a) an aggregate of 1,446,525 SPAC Class B Ordinary Shares held by Sponsor will be surrendered for nil consideration; and (b) after such surrender, each of the remaining SPAC Class B Ordinary Shares issued and outstanding immediately prior to the First Merger Effective Time and held by the SPAC Insiders (and the SPAC Class A Ordinary Shares into which such SPAC Class B Ordinary Shares are convertible or converted) shall automatically be cancelled and cease to exist in exchange for the right to receive, upon delivery of the applicable Letter of Transmittal (if any) in accordance with Section 2.4, one newly issued Company Ordinary Share; and

(3)            each SPAC Class B Ordinary Share held by a Forward Purchase Investor and its permitted transferees (and the SPAC Class A Ordinary Shares into which such SPAC Class B Ordinary Shares are convertible or converted) issued and outstanding immediately prior to the First Merger Effective Time shall automatically be cancelled and cease to exist in exchange for the right to receive, upon delivery of the applicable Letter of Transmittal (if any) in accordance with Section 2.4, (a) such fraction of a newly issued Company Ordinary Share that is equal to the SPAC Class A Exchange Ratio, without interest, subject to rounding pursuant to Section 2.4(e), if and only if such Forward Purchase Investor has fully delivered its portion of the Forward Purchase Investment Amount as required under the applicable Forward Purchase Agreement and, failing that, (b) one newly issued Company Ordinary Share;

21

As of the First Merger Effective Time, each SPAC Shareholder shall cease to have any other rights in and to such SPAC Shares, except as expressly provided in Section 2.2(h)(v) and Section 2.2(h)(vi).

(iii)         Exchange of SPAC Warrants. Each SPAC Warrant (which, for the avoidance of doubt, includes (1) the SPAC Warrants held by public SPAC warrantholders as a result of the Unit Separation, (2) the SPAC Warrants held by the Sponsor, and (3) the SPAC Warrants held by the Forward Purchase Investors) outstanding immediately prior to the First Merger Effective Time shall cease to be a warrant with respect to SPAC Ordinary Shares and be assumed by the Company and converted into a warrant to purchase one Company Ordinary Share (each, a “Company Warrant”). Each Company Warrant shall continue to have and be subject to substantially the same terms and conditions as were applicable to such SPAC Warrant immediately prior to the First Merger Effective Time (including any repurchase rights and cashless exercise provisions) in accordance with the provisions of the Warrant Assignment Agreement.

(iv)          SPAC Treasury Shares. Notwithstanding Section 2.2(h)(ii) above or any other provision of this Agreement to the contrary, if there are any SPAC Shares that are owned by SPAC as treasury shares or any SPAC Shares owned by any direct or indirect Subsidiary of SPAC immediately prior to the First Merger Effective Time, such SPAC Shares shall be cancelled and shall cease to exist without any conversion thereof or payment or other consideration therefor.

(v)            Redeeming SPAC Shares. Each Redeeming SPAC Share issued and outstanding immediately prior to the First Merger Effective Time shall be cancelled and cease to exist and shall thereafter represent only the right to be paid a pro rata share of the SPAC Shareholder Redemption Amount in accordance with SPAC’s Charter.

(vi)          Dissenting SPAC Shares. Each Dissenting SPAC Share issued and outstanding immediately prior to the First Merger Effective Time held by a Dissenting SPAC Shareholder shall be cancelled and cease to exist in accordance with Section 2.6(a) and shall thereafter represent only the right to be paid the fair value of such Dissenting SPAC Share and such other rights pursuant to Section 238 of the Cayman Act.

(vii)         Merger Sub Shares. At the First Merger Effective Time, the Merger Sub I Share issued and outstanding immediately prior to the First Merger Effective Time shall automatically convert into one ordinary share, par value $0.0001 per share, of the Surviving Entity. The ordinary share of the Surviving Entity shall have the same rights, powers and privileges as the shares so converted and shall constitute the only issued and outstanding share capital of the Surviving Entity. At the Second Merger Effective Time, each share of the Surviving Entity that is issued and outstanding immediately prior to the Second Merger Effective Time will be automatically cancelled and extinguished without any conversion thereof or payment therefor. The Merger Sub II Share that is issued and outstanding immediately prior to the Second Merger Effective Time shall remain outstanding and shall not be affected by the Second Merger.

Section 2.3            Closing.

(a)            On the terms and subject to the conditions of this Agreement, the consummation of the Mergers (the “Closing”, and the day on which the Closing occurs, the “Closing Date”) shall take place remotely by conference call and exchange of documents and signatures in accordance with Section 11.9 on the date that is three (3) Business Days after the first date on which all conditions set forth in Article IX that are required hereunder to be satisfied on or prior to the Closing shall have been satisfied or waived (other than those conditions that by their terms are to be satisfied at the Closing, but subject to the satisfaction or waiver thereof), unless extended in accordance with Section 2.6(c) or at such other time or in such other manner as shall be agreed upon by SPAC and the Company in writing; provided that if the First Merger and the Second Merger are not consummated on the same day, references to the Closing and the Closing Date shall be construed to mean the consummation of the First Merger and the date of the First Merger Effective Time, respectively, and each party hereto shall take all actions within its power as may be necessary or appropriate such that the Second Merger is consummated as promptly as reasonably practicable after the Closing.

22

(b)            Prior to or on the Closing Date,

(v)           the SPAC shall deliver or cause each SPAC Insider to deliver to the Company, a deed of adherence duly executed by such SPAC Insider in substantially the form of Annex I attached to the Shareholder Support Agreement, effective on or prior to the First Merger Effective Time;

(vi)           the Company shall deliver or cause each Company Shareholder (if not already a party to the Shareholders Support Agreement) to deliver to SPAC, a deed of adherence duly executed by such Company Shareholder in substantially the form of Annex I attached to the Shareholder Support Agreement, effective on or prior to the First Merger Effective Time;

(vii)         the Company and SPAC (or the Surviving Entity following the First Merger and the Surviving Company following the Second Merger), shall:

(1)            cause any documents, opinions and notices required to be delivered to the Trustee pursuant to the Trust Agreement to be so delivered;

(2)            pay, or cause the Trustee to pay at the direction and on behalf of SPAC (or the Surviving Entity following the First Merger and the Surviving Company following the Second Merger), by wire transfer of immediately available funds from the Trust Account (A) as and when due all amounts payable on account of the SPAC Shareholder Redemption Amount to former SPAC Shareholders pursuant to their exercise of the SPAC Shareholder Redemption Right, (B) all accrued and unpaid Company Transaction Expenses and, subject to Section 11.6, all accrued and unpaid SPAC Transaction Expenses, each as set forth on a written statement to be delivered to the Surviving Company by or on behalf of the Company and SPAC, respectively, not less than two (2) Business Days prior to the Closing Date, which shall include the respective amounts and wire transfer instructions for the payment thereof, and (C) immediately thereafter, all remaining amounts then available in the Trust Account (if any) (the “Remaining Trust Fund Proceeds”) to a bank account designated by the Company for its immediate use, subject to this Agreement (including, for the avoidance of doubt, Section 8.7) and the Trust Agreement; and

(3)            thereafter, the Trust Account shall terminate, except as otherwise provided in the Trust Agreement.

23

Section 2.4            Cancellation of SPAC Equity Securities and Disbursement of Merger Consideration.

(a)            Prior to the First Merger Effective Time, the Company shall appoint an exchange agent reasonably acceptable to the Company and SPAC as exchange agent (for the avoidance of doubt, Continental Stock Transfer & Trust Company shall be deemed to be reasonably acceptable to SPAC) (in such capacity, the “Exchange Agent”), for the purpose of exchanging SPAC Ordinary Shares for the Merger Consideration in accordance with the Plan of First Merger and this Agreement, and paying the Merger Consideration to the SPAC Shareholders. At or before the First Merger Effective Time, the Company shall deposit, or cause to be deposited, with the Exchange Agent the Merger Consideration.

(b)            If the Exchange Agent requires that, as a condition to receive the Merger Consideration, any SPAC Shareholder deliver a letter of transmittal to the Exchange Agent, then at or as promptly as practicable following the First Merger Effective Time, the Company shall send, or shall cause the Exchange Agent to send, to each SPAC Shareholder a letter of transmittal (which shall specify that the delivery shall be effected, and the risk of loss and title shall pass, only upon proper transfer of each share to the Exchange Agent, and which letter of transmittal will be in customary form and have such other provisions as SPAC and the Company may reasonably specify) for use in such exchange (each, a “Letter of Transmittal”). Notwithstanding anything to the contrary contained herein, any obligation on the Company under this Agreement to issue Company Ordinary Shares to SPAC Shareholders entitled to receive Company Ordinary Shares may be satisfied by the Company issuing such Company Ordinary Shares, and shall be deemed to have been satisfied upon issuance of such Company Ordinary Shares, (i) to the DTC or to such other clearing service or issuer of depositary receipts (or their nominees, in either case) as may be necessary or expedient, and each SPAC Shareholder shall hold such Company Ordinary Shares in book-entry form or through a holding of depositary receipts and the DTC or its nominee or the relevant clearing service or issuer of depositary receipts (or their nominees, as the case may be), will be the holder of record of such Company Ordinary Shares or (ii) directly to each SPAC Shareholder by entering such SPAC Shareholder on the register of members maintained by the Company (or its share registrar) for the Company Ordinary Shares.

(c)            Each SPAC Shareholder shall be entitled to receive its portion of the Merger Consideration, pursuant to Section 2.2(h)(ii) (excluding any SPAC Shares referred to in Section 2.2(h)(iv), Redeeming SPAC Shares and any Dissenting SPAC Shares) upon the receipt of an “agent’s message” by the Exchange Agent (or such other evidence, if any, of transfer as the Exchange Agent may reasonably request), together with a duly completed and validly executed Letter of Transmittal (if required by the Exchange Agent in accordance with Section 2.4(b)) and such other documents as may reasonably be requested by the Exchange Agent. No interest shall be paid or accrued upon the transfer of any share.

(d)            Promptly following the date that is one (1) year after the First Merger Effective Time, the Company shall instruct the Exchange Agent to deliver to the Company all documents in its possession relating to the transactions contemplated hereby, and the Exchange Agent’s duties shall terminate. Thereafter, any portion of the Merger Consideration that remains unclaimed shall be returned to the Company and the unclaimed Company Ordinary Shares comprising the Merger Consideration shall be held by the Company as treasury shares, and any Person that was a holder of SPAC Shares (other than any SPAC Shares referred to in Section 2.2(h)(iv), Redeeming SPAC Shares and Dissenting SPAC Shares) as of immediately prior to the First Merger Effective Time that has not claimed their applicable portion of the Merger Consideration in accordance with this Section 2.4 prior to the date that is one (1) year after the First Merger Effective Time, may (subject to applicable abandoned property, escheat and similar Laws) claim from the Company, and the Company shall promptly transfer and deliver, such applicable portion of the Merger Consideration without any interest thereupon. None of SPAC, the Company, the Merger Subs, the Surviving Entity, the Surviving Company or the Exchange Agent shall be liable to any Person in respect of any of the Merger Consideration delivered to a public official pursuant to and in accordance with any applicable abandoned property, escheat or similar Laws. If any such Merger Consideration shall not have been claimed immediately prior to such date on which any amounts payable pursuant to this Article II would otherwise escheat to or become the property of any Governmental Authority, any such amount shall be cancelled by the Company.

24

(e)            Notwithstanding anything to the contrary contained herein, no fraction of a Company Ordinary Share will be issued by virtue of the Mergers or the other Transactions under this Section 2.4, and each Person who would otherwise be entitled to a fraction of a Company Ordinary Share (after aggregating all fractional Company Ordinary Shares that otherwise would be received by such holder) shall instead have the number of Company Ordinary Shares issued to such Person rounded down in the aggregate to the nearest whole Company Ordinary Share.

Section 2.5            Further Assurances. If, at any time after the First Merger Effective Time, any further action is necessary, proper or advisable to carry out the purposes of this Agreement, the Surviving Entity, the Surviving Company, Merger Sub II and the Company (or their respective designees) shall take all such actions as are necessary, proper or advisable under applicable Laws, so long as such action is consistent with and for the purposes of implementing the provisions of this Agreement.

Section 2.6            Dissenter’s Rights.

(a)            Subject to Section 2.2(c)(ii) but notwithstanding any other provision of this Agreement to the contrary and to the extent available under the Cayman Act, SPAC Shares that are issued and outstanding immediately prior to the First Merger Effective Time and that are held by SPAC Shareholders who shall have validly exercised their dissenters’ rights for such SPAC Shares in accordance with Section 238 of the Cayman Act and otherwise complied with all of the provisions of the Cayman Act relevant to the exercise and enforcement of dissenters’ rights (the “Dissenting SPAC Shares”, and the holders of such Dissenting SPAC Shares being the “Dissenting SPAC Shareholders”) shall be cancelled and cease to exist at the First Merger Effective Time and the Dissenting SPAC Shareholders shall not be entitled to receive the applicable Merger Consideration and shall instead be entitled to receive only the payment of the fair value of such Dissenting SPAC Shares held by them as determined in accordance with the provisions of Section 238 of the Cayman Act. For the avoidance of doubt, the SPAC Shares owned by any SPAC Shareholder who fails to exercise or who effectively withdraws or otherwise loses his, her or its dissenters’ rights pursuant to Section 238 of the Cayman Act shall not be Dissenting SPAC Shares and shall thereupon be cancelled and cease to exist at the First Merger Effective Time, in exchange for the right to receive the applicable Merger Consideration, without any interest thereon in accordance with Section 2.2(h)(ii).

(b)            Prior to the Closing, SPAC shall give the Company (i) prompt written notice of any demands for dissenters’ rights received by SPAC from SPAC Shareholders and any withdrawals of such demands and (ii) the opportunity to direct all negotiations and proceedings with respect to any such notice or demand for dissenters’ rights under the Cayman Act. SPAC shall not, except with the prior written consent of the Company, make any offers or payment or otherwise agree or commit to any payment or other consideration with respect to any exercise by a SPAC Shareholder of its rights to dissent from the First Merger or any demands for appraisal or offer or agree or commit to settle or settle any such demands or approve any withdrawal of any such dissenter rights or demands.

(c)            If any SPAC Shareholder gives to SPAC, before the SPAC Shareholders’ Approval is obtained at the SPAC Shareholders’ Meeting, written objection to the First Merger (each, a “Written Objection”) in accordance with Section 238(2) of the Cayman Act:

(i)            SPAC shall, in accordance with Section 238(4) of the Cayman Act, promptly give written notice of the authorization of the First Merger (the “Authorization Notice”) to each such SPAC Shareholder who has made a Written Objection, and

(ii)            unless SPAC and the Company elect by agreement in writing to waive this Section 2.6(c)(ii), no party shall be obligated to commence the Closing, and the Plan of First Merger shall not be filed with the Registrar of Companies of the Cayman Islands, until at least twenty (20) days shall have elapsed since the date on which the Authorization Notice is given (being the period allowed for written notice of an election to dissent under Section 238(5) of the Cayman Act, as referred to in Section 239(1) of the Cayman Act), but in any event subject to the satisfaction or waiver of all of the conditions set forth in Section 9.1, Section 9.2 and Section 9.3.

25

Section 2.7            Withholding. Each of the parties hereto and any other applicable withholding agent (and their respective Affiliates and Representatives) shall be entitled to deduct and withhold from any amount otherwise payable pursuant to this Agreement such amount as it is required to deduct and withhold with respect to the making of such payment under the Code, or any provision of state, local or non-U.S. Tax Law. The parties hereto shall use commercially reasonable efforts to notify the Person in respect of whom such deduction or withholding is expected to be made prior to making any such deduction or withholding, which notice shall be in writing and include the amount of and basis for such deduction or withholding. The parties hereto shall use commercially reasonable efforts to cooperate and reduce or eliminate any such deduction or withholding to the extent permitted by applicable Law. To the extent that amounts are so deducted or withheld, and paid over to the appropriate Governmental Authority, such deducted or withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction or withholding was made.

To the Knowledge of SPAC, none of the SPAC SEC Filings filed on or prior to the date of this Agreement is subject to ongoing SEC review or investigation as of the date of this Agreement.

Section 4.13          Trust Account. As of the date of this Agreement, SPAC has at least $200,000,000 in the Trust Account, such monies invested in United States government securities or money market funds meeting certain conditions under Rule 2a-7 promulgated under the Investment Company Act pursuant to the Investment Management Trust Agreement, dated as of June 8, 2021, between SPAC and Continental Stock Transfer & Trust Company, as trustee (in such capacity, the “Trustee”, and such Investment Management Trust Agreement, the “Trust Agreement”). Except for the BofA Waiver Letter, there are no separate Contracts or side letters that would cause the description of the Trust Agreement in the SPAC SEC Filings to be inaccurate in any material respect or that would entitle any Person (other than SPAC Shareholders holding SPAC Ordinary Shares (prior to the First Merger Effective Time) sold in SPAC’s IPO who shall have elected to redeem their SPAC Ordinary Shares (prior to the First Merger Effective Time) pursuant to the SPAC Charter) to any portion of the proceeds in the Trust Account. Prior to the Closing, none of the funds held in the Trust Account may be released other than to pay Taxes and payment to SPAC Shareholders who have validly exercised their redemption rights pursuant to the SPAC Charter. There are no Actions pending or, to the Knowledge of SPAC, threatened with respect to the Trust Account. SPAC has performed all material obligations required to be performed by it to date under, and is not in default, breach or delinquent in performance or any other respect (claimed or actual) in connection with, the Trust Agreement, and no event has occurred which, with due notice or lapse of time or both, would constitute such a default or breach thereunder. As of the Closing, the obligations of SPAC to dissolve or liquidate pursuant to the SPAC Charter shall terminate, and as of the Closing, SPAC shall have no obligation whatsoever pursuant to the SPAC Charter to dissolve and liquidate the assets of SPAC by reason of the consummation of the Transactions. As of the date of this Agreement, following the Closing, no SPAC Shareholder is entitled to receive any amount from the Trust Account except to the extent such SPAC Shareholder has exercised his, her or its SPAC Shareholder Redemption Right. As of the date of this Agreement, assuming the accuracy of the representations and warranties contained in Article III and the compliance by each of the Company and the Merger Subs with its obligations hereunder, SPAC has no reason to believe that any of the conditions to the use of funds in the Trust Account will not be satisfied or funds available in the Trust Account will not be available to the Surviving Company (as the surviving entity in the Second Merger) on the Closing Date.

With respect to each Forward Purchase Investor, the Forward Purchase Agreement with such Forward Purchase Investor is in full force and effect and has not been withdrawn or terminated, or otherwise amended or modified, in any material respect, and no withdrawal or termination, or amendment or modification in any material respect is contemplated by SPAC. Each Forward Purchase Agreement is a legal, valid and binding obligation of SPAC and each Forward Purchase Investor, and neither the execution or delivery by any party thereto nor the performance of any party’s obligations under any such Forward Purchase Agreement violates any Laws. The Forward Purchase Agreements contain all of the conditions precedent (other than the conditions contained in the other Transaction Documents) to the obligations of the Forward Purchase Investors to fund the applicable portion of the Forward Purchase Investment Amount set forth in the Forward Purchase Agreements on the terms therein.

(i)            Prior to or as promptly as practicable after the Proxy/Registration Statement is declared effective under the Securities Act, SPAC shall establish a record date for, duly call, give notice of, convene and hold a meeting of the SPAC Shareholders (including any adjournment or postponement thereof, the “SPAC Shareholders’ Meeting”) in accordance with the SPAC Charter to be held as promptly as reasonably practicable and, unless otherwise agreed by SPAC and the Company in writing, in any event not more than thirty (30) days following the date that the Proxy/Registration Statement is declared effective under the Securities Act for the purpose of voting on the Transaction Proposals and obtaining the SPAC Shareholders’ Approval (including the approval of any adjournment or postponement of such meeting for the purpose of soliciting additional proxies in favor of the adoption of the Transaction Proposals), providing SPAC Shareholders with the opportunity to elect to exercise their SPAC Shareholder Redemption Right and such other matters as may be mutually agreed by SPAC and the Company. SPAC will use its reasonable best efforts (A) to solicit from its shareholders proxies in favor of the adoption of the Transaction Proposals, including the SPAC Shareholders’ Approval, and will take all other action necessary or advisable to obtain such proxies and SPAC Shareholders’ Approval and (B) to obtain the vote or consent of its shareholders required by and in compliance with all applicable Law, Nasdaq rules and the SPAC Charter. SPAC (x) shall consult with the Company regarding the record date and the date of the SPAC Shareholders’ Meeting prior to determining such dates and (y) shall not adjourn or postpone the SPAC Shareholders’ Meeting without the prior written consent of Company (which consent shall not be unreasonably withheld, conditioned or delayed); provided, however, that SPAC shall adjourn or postpone the SPAC Shareholders’ Meeting (1) to the extent necessary to ensure that any supplement or amendment to the Proxy/Registration Statement that SPAC or the Company reasonably determines (following consultation with the Company, except with respect to any Company Acquisition Proposal) is necessary to comply with applicable Laws, is provided to the SPAC Shareholders in advance of a vote on the adoption of the Transaction Proposals, (2) if, as of the time that the SPAC Shareholders’ Meeting is originally scheduled, there are insufficient SPAC Shares represented at such meeting (either in person or by proxy) to constitute a quorum necessary to conduct the business of the SPAC Shareholders’ Meeting, (3) if, as of the time that the SPAC Shareholders’ Meeting is originally scheduled, adjournment or postponement of the SPAC Shareholders’ Meeting is necessary to enable SPAC to solicit additional proxies required to obtain SPAC Shareholders’ Approval, (4) in order to seek withdrawals from SPAC Shareholders who have exercised their SPAC Shareholder Redemption Right if a number of SPAC Shares have been elected to be redeemed such that SPAC reasonably expects that the condition set forth in Section 9.3(c) will not be satisfied at the Closing; or (5) to comply with applicable Law; provided, further, however, that without the prior written consent of the Company (such consent not to be unreasonably withheld, delayed or conditioned), SPAC shall not adjourn or postpone on more than two (2) occasions and so long as the date of the SPAC Shareholders’ Meeting is not adjourned or postponed more than an aggregate of thirty (30) consecutive days.

(ii)           The Proxy/Registration Statement shall include a statement to the effect that SPAC Board has unanimously recommended that the SPAC Shareholders vote in favor of the Transaction Proposals at the SPAC Shareholders’ Meeting (such statement, the “SPAC Board Recommendation”) and neither the SPAC Board nor any committee thereof shall withhold, withdraw, qualify, amend or modify, or publicly propose or resolve to withhold, withdraw, qualify, amend or modify, the SPAC Board Recommendation.

Section 8.4            Tax Matters.

(a)            Each of SPAC, Merger Sub I, Merger Sub II, and the Group Companies shall (and shall cause their respective Affiliates to) cooperate fully, as and to the extent reasonably requested by each other, in connection with the filing of relevant Tax Returns and the defense of relevant Tax audits or other similar proceedings. Such cooperation shall include retaining and (upon reasonable request) providing (with the right to make copies) records and information reasonably relevant to any such Tax Returns or Tax audits or other similar proceedings, making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder, and, to the extent applicable, (i) making available to holders of SPAC Securities factual information reasonably necessary and in such person’s possession or reasonably available to it to determine whether the Mergers may qualify for nonrecognition treatment, in whole or in part, under any provision of the Code (it being understood that (A) such holders shall rely on their own Tax advisors, and shall not rely on SPAC, the Merger Subs, the Group Companies, or any of their respective Affiliates or advisors, to make such determination and (B) no information so made available shall be construed as any representation by SPAC, the Merger Subs, the Group Companies, or any of their respective Affiliates or advisors with respect to the Tax treatment of the Transactions) and (ii) making available to SPAC Shareholders information reasonably necessary to compute the taxable income of SPAC Shareholders (or their direct or indirect owners) arising as a result of SPAC’s status as a PFIC or a “controlled foreign corporation” within the meaning of Section 957(a) of the Code for any taxable period (or portion thereof) beginning on or before the Closing Date, including timely providing a PFIC Annual Information Statement (as described in Treasury Regulations Section 1.1295-1(g)) to enable SPAC Shareholders to make and maintain a “Qualified Electing Fund” election under Section 1295 of the Code and the Treasury Regulations promulgated thereunder and information to enable SPAC Shareholders to report their allocable share of “subpart F” income under Section 951 of the Code and “global intangible low-taxed income” under Section 951A of the Code.

(b)            The Company shall, following the close of the taxable year in which the Closing occurs and the following taxable year, determine whether it is a PFIC. If the Company determines after the Closing that it is a PFIC for the taxable year in which the Closing occurs and the following taxable year, the Company shall also determine if any of its Subsidiaries is a PFIC and the Company shall provide sufficient information to its stockholders to enable them to make and maintain a timely and valid “Qualified Electing Fund” election under Section 1295 of the Code and the Treasury Regulations promulgated thereunder for the Company and any Subsidiary of the Company that is a PFIC.

60

(c)            Upon the written request of a Company Shareholder or a SPAC Shareholder (or any direct or indirect owner thereof) that is a U.S. person for U.S. federal income Tax purposes and owns five percent (5%) or more of the Company immediately after the Closing (directly or constructively, as determined under applicable Treasury Regulations), the Company shall use reasonable best efforts to (i) furnish to such Person such information as such Person reasonably requests in connection with such Person’s preparation of any “gain recognition agreement” in accordance with Treasury Regulations Section 1.367(a)-8 and (ii) provide such Person with the information reasonably requested by such Person for purposes of determining whether there has been any “triggering event” (or potential “triggering event”) as defined in Treasury Regulations Section 1.367(a)-8(j) under the terms of such agreement and, as applicable, information reasonably requested by such Person in connection with such triggering event to make a substitute gain recognition agreement.

  

(d)            If, due to a change in United States Tax Law following the date of this Agreement, Merger Sub II is not able to obtain the United States entity classification described in Section 5.11 (i.e., as a “disregarded entity”), the parties hereto shall use commercially reasonable efforts to consummate the acquisition of SPAC by the Company in a manner that is as equivalent as practicable, for United States Tax purposes, to the transactions described herein; provided that any action to be taken pursuant to this Section 8.4(d) shall not cause any material delay to, or result in any material adverse effect on, the Closing.

(e)            All Transfer Taxes will be borne by the party responsible therefor under applicable Law.

Section 8.5            Shareholder Litigation. The Company shall promptly advise SPAC, and SPAC, shall promptly advise the Company, as the case may be, of any Action commenced (or to the Knowledge of the Company or the Knowledge of SPAC, as applicable, threatened) on or after the date of this Agreement against such party, any of its Subsidiaries or any of its directors or officers by any Company Shareholder or SPAC Shareholder relating to this Agreement, the Mergers or any of the other Transactions (any such Action, “Shareholder Litigation”), and such party shall keep the other party reasonably informed regarding any such Shareholder Litigation. Other than with respect to any Shareholder Litigation where the parties identified in this sentence are adverse to each other or in the context of any Shareholder Litigation related to or arising out of a Company Acquisition Proposal or a SPAC Acquisition Proposal, (a) the Company shall give SPAC a reasonable opportunity to participate in the defense or settlement of any such Shareholder Litigation (and consider in good faith the suggestions of SPAC in connection therewith) brought against the Company, any of their respective Subsidiaries or any of their respective directors or officers and no such settlement shall be agreed to without the SPAC’s prior consent (which consent shall not be unreasonably withheld, conditioned or delayed) and (b) SPAC shall give the Company a reasonable opportunity to participate in the defense or settlement of any such Shareholder Litigation (and consider in good faith the suggestions of the Company in connection therewith) brought against SPAC, any of its Subsidiaries or any of its directors or officers, and no such settlement shall be agreed to without the Company’s prior consent (which consent shall not be unreasonably withheld, conditioned or delayed).

61

Section 8.6            Forward Purchase Subscriptions. Unless otherwise consented in writing by each of the Company and SPAC (which consent shall not be unreasonably withheld, conditioned or delayed), SPAC shall not permit any amendment or modification to be made to, any waiver (in whole or in part) or provide consent to (including consent to termination), any provision or remedy under, or any replacements of, any of the Forward Purchase Agreements. The SPAC shall procure that the Forward Purchase Investors perform their respective obligations under their respective Forward Purchase Agreements and complete the consummation of their respective Forward Purchase Subscriptions in full immediately prior to the First Merger Effective Time. Each of the parties shall use its commercially reasonable efforts to 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 the Forward Purchase Agreements on the terms and conditions described therein, including maintaining in effect the Forward Purchase Agreements and to: (a) satisfy on a timely basis all conditions and covenants applicable to it in the Forward Purchase Agreements and otherwise comply with its obligations thereunder, (b) without limiting the rights of any party to enforce certain of such Forward Purchase Agreements in the event that all conditions in the Forward Purchase Agreements (other than conditions that the Company, SPAC or any of its Affiliates control the satisfaction of and other than those conditions that by their nature are to be satisfied at the closings under the Forward Purchase Agreements) have been satisfied, consummate the transactions contemplated by the Forward Purchase Agreements at or prior to the Closing; (c) confer with each other regarding timing of the expected closings under the Forward Purchase Agreements; and (d) deliver notices to the applicable counterparties to the Forward Purchase Agreements sufficiently in advance of the Closing to cause them to fund their obligations as far in advance of the Closing as permitted by the Forward Purchase Agreements. Without limiting the generality of the foregoing, SPAC shall give the Company prompt written notice: (A) of any breach or default (or any event or circumstance that, with or without notice, lapse of time or both, could give rise to any breach or default) by any party to any Forward Purchase Agreement known to; (B) of the receipt of any notice or other communication from any party to any Forward Purchase Agreement by SPAC with respect to any actual, potential, threatened or claimed expiration, lapse, withdrawal, material breach, material default, termination or repudiation by any party to any Forward Purchase Agreement or any provisions of any Forward Purchase Agreement; and (C) if SPAC does not expect to receive, all or any portion of the Forward Purchase Investment Amount on the terms, in the manner or from the Forward Purchase Investors as contemplated by the Forward Purchase Agreements. SPAC shall take all actions required under the Forward Purchase Agreements with respect to the timely book-entry or issuance and delivery of any physical certificates evidencing the SPAC Ordinary Shares and the SPAC Warrants as and when required under any such Forward Purchase Agreements.

  

Section 8.7            Use of Remaining Trust Fund Proceeds. Subject to the satisfaction or waiver of the conditions set forth in Article IX (other than those conditions that by their nature are to be satisfied at the Closing, but subject to the satisfaction or waiver of such conditions), of the Remaining Trust Fund Proceeds, an amount equal to the lesser of (a) 50% of all amounts in the Trust Account immediately prior to the Closing, without taking into account of the SPAC Shareholder Redemption Amount, and (b) all amounts in the Trust Account immediately prior to the Closing, taking into account the SPAC Shareholder Redemption Amount, shall remain with the Company and be (i) used in the operations of the Company or the members of the Company’s “qualified group” within the meaning of Treasury Regulations Section 1.368-1(d)(4)(ii) and/or (ii) loaned to the Group Companies to be used in the business operations of the Group Companies, in each case, such amounts to be used in a manner that would not impair the ability of the Mergers, taken together, to qualify as a “reorganization” within the meaning of Section 368 of the Code. Notwithstanding the foregoing, none of SPAC or the Group Companies make any representation regarding whether the Mergers, taken together, will qualify as a “reorganization” within the meaning of Section 368 of the Code.

MISCELLANEOUS

  

Section 11.1          Trust Account Waiver. Notwithstanding anything to the contrary set forth in this Agreement, each of the Company and the Merger Subs acknowledges that it has read the publicly filed final prospectus of SPAC, filed with the SEC on June 10, 2021 (File No. 333-255722), including the Trust Agreement, and understands that SPAC has established the trust account described therein (the “Trust Account”) for the benefit of SPAC’s public shareholders and that disbursements from the Trust Account are available only in the limited circumstances set forth therein. Each of the Company and the Merger Subs further acknowledges and agrees that SPAC’s sole assets consist of the cash proceeds of SPAC’s initial public offering (the “IPO”) and private placements of its securities occurring simultaneously with the IPO, and that substantially all of these proceeds have been deposited in the Trust Account for the benefit of its public shareholders. Accordingly, the Company (on behalf of itself and its Affiliates) and the Merger Subs hereby waive any past, present or future claim of any kind arising out of this Agreement against, and any right to access, the Trust Account, any trustee of the Trust Account or SPAC, to collect from the Trust Account any monies that may be owed to them by SPAC or any of its Affiliates for any reason whatsoever, and will not seek recourse against the Trust Account at any time for any reason whatsoever, including for any knowing and intentional breach by any of the parties to this Agreement of any of its representations or warranties as set forth in this Agreement, or such party’s material breach of any of its covenants or other agreements set forth in this Agreement, which material breach constitutes, or is a consequence of, a purposeful act or failure to act by such party with the knowledge that the taking of such act or failure to take such act would cause a material breach of this Agreement. This Section 11.1 shall survive the termination of this Agreement for any reason.

PROMISSORY NOTE

Dated as of September 29, 2022

Principal Amount: up to $1,500,000

(as set forth on the Schedule of Borrowings attached hereto as Exhibit A)

Summit Healthcare Acquisition Corp., a Cayman Islands exempted company (the “Maker”), promises to pay to the order of Summit Healthcare Acquisition Sponsor LLC, a Cayman Islands limited liability company, or its registered assigns or successors in interest (the “Payee”), the principal sum of up to One Million and Five Hundred Thousand U.S. dollars ($1,500,000) (as set forth on the Schedule of Borrowings attached hereto as Exhibit A) in lawful money of the United States of America, on the terms and conditions described below. All payments on this Note shall be made by check or wire transfer of immediately available funds or as otherwise determined by the Maker to such account as the Payee may from time to time designate by written notice in accordance with the provisions of this Note.

1.            Principal. The principal balance of this Note shall be payable by the Maker in full on the date (such date, the “Maturity Date”) on which the Maker consummates an initial merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (an “Initial Business Combination”), unless earlier accelerated upon the occurrence of an Event of Default (as defined herein). The principal balance may be prepaid by the Maker at any time without penalty. Under no circumstances shall any individual, including but not limited to any officer, director, employee or shareholder of the Maker, be obligated personally for any obligations or liabilities of the Maker hereunder.

2.            Conversion at the Option of the Payee. At any time and from time to time, at the option of the Payee, all or a portion of any unpaid and outstanding principal balance of this Note, subject to this paragraph 2, may be convertible into one or more redeemable warrants (the “Working Capital Warrants”), with each $1.00 of unpaid and outstanding principal balance of this Note being convertible into one Working Capital Warrant (a “Conversion”). Each Working Capital Warrant, when and if issued, will entitle the Payee to purchase one Class A ordinary share of the Maker, par value $0.0001 per share (each, an “Ordinary Share”), at an exercise price of $11.50 per Ordinary Share, subject to adjustment, and will otherwise have the terms set forth in that certain Warrant Agreement, dated June 8, 2021, entered into by the Maker and Continental Stock Transfer & Trust Company, as the same may be amended, restated or supplemented.

3.            Interest. No interest shall accrue on the unpaid principal balance of this Note.

4.            Drawdown Requests. The Maker and the Payee agree that the Maker may request up to One Million and Five Hundred Thousand U.S. Dollars ($1,500,000) in the aggregate for costs and expenses reasonably related to the Maker’s working capital needs prior to the consummation of the Initial Business Combination. The principal of this Note may be drawn down from time to time prior to the Maturity Date, upon written request from the Maker to the Payee (each, a “Drawdown Request”). Each Drawdown Request must state the amount to be drawn down, and must not be an amount less than One Thousand Dollars ($1,000) unless agreed upon by Maker and Payee. Payee shall fund each Drawdown Request no later than three (3) business day after receipt of a Drawdown Request; provided, however, that the maximum amount of drawdowns collectively under this Note is One Million and Five Hundred Thousand Dollars ($1,500,000). No fees, payments or other amounts shall be due to the Payee in connection with, or as a result of, any Drawdown Request by Maker.

5.            Application of Payments. All payments shall be applied first to payment in full of any costs incurred in the collection of any sum due under this Note, including (without limitation) reasonable attorney’s fees, then to the payment in full of any late charges and finally to the reduction of the unpaid principal balance of this Note.

6.            Events of Default. The occurrence of any of the following shall constitute an event of default (“Event of Default”):

(a)            Failure to Make Required Payments. Failure by the Maker to pay the principal amount due pursuant to this Note within five (5) business days of the Maturity Date.

(b)            Voluntary Bankruptcy, Etc. The commencement by the Maker of a voluntary case under any applicable bankruptcy, insolvency, reorganization, rehabilitation or other similar law, or the consent by it to the appointment of or taking possession by a receiver, liquidator, assignee, trustee, custodian, sequestrator (or other similar official) of the Maker or for any substantial part of its property, or the making by it of any assignment for the benefit of creditors, or the failure of the Maker generally to pay its debts as such debts become due, or the taking of corporate action by the Maker in furtherance of any of the foregoing.

(c)            Involuntary Bankruptcy, Etc. The entry of a decree or order for relief by a court having jurisdiction in the premises in respect of the Maker in an involuntary case under any applicable bankruptcy, insolvency or other similar law, or appointing a receiver, liquidator, assignee, custodian, trustee, sequestrator (or similar official) of the Maker or for any substantial part of its property, or ordering the winding-up or liquidation of its affairs, and the continuance of any such decree or order unstayed and in effect for a period of 60 consecutive days.

7.            Remedies.

(a)            Upon the occurrence of an Event of Default specified in Section 6(a) hereof, the Payee may, by written notice to the Maker, declare this Note to be due immediately and payable, whereupon the unpaid principal amount of this Note, and all other amounts payable hereunder, shall become immediately due and payable without presentment, demand, protest or other notice of any kind, all of which are hereby expressly waived, anything contained herein or in the documents evidencing the same to the contrary notwithstanding.

2

(b)            Upon the occurrence of an Event of Default specified in Sections 6(b) and 6(c) hereof, the unpaid principal balance of this Note, and all other sums payable with regard to this Note, shall automatically and immediately become due and payable, in all cases without any action on the part of the Payee.

8.            Waivers. The Maker and all endorsers and guarantors of, and sureties for, this Note waive presentment for payment, demand, notice of dishonor, protest and notice of protest with regard to the Note, all errors, defects and imperfections in any proceedings instituted by the Payee under the terms of this Note, and all benefits that might accrue to Maker by virtue of any present or future laws exempting any property, real or personal, or any part of the proceeds arising from any sale of any such property, from attachment, levy or sale under execution, or providing for any stay of execution, exemption from civil process, or extension of time for payment; and Maker agrees that any real estate that may be levied upon pursuant to a judgment obtained by virtue hereof, on any writ of execution issued hereon, may be sold upon any such writ in whole or in part in any order desired by Payee.

9.            Unconditional Liability. The Maker hereby waives all notices in connection with the delivery, acceptance, performance, default, or enforcement of the payment of this Note, and agrees that its liability shall be unconditional, without regard to the liability of any other party, and shall not be affected in any manner by any indulgence, extension of time, renewal, waiver or modification granted or consented to by the Payee, and consents to any and all extensions of time, renewals, waivers or modifications that may be granted by the Payee with respect to the payment or other provisions of this Note, and agrees that additional makers, endorsers, guarantors or sureties may become parties hereto without notice to the Maker or affecting the Maker’s liability hereunder.

10.            Notices. All notices, statements or other documents which are required or contemplated by this Note shall be: (i) in writing and delivered personally or sent by first class registered or certified mail, overnight courier service or facsimile or electronic transmission to the address designated in writing, (ii) by facsimile to the number most recently provided to such party or such other address or fax number as may be designated in writing by such party or (iii) by electronic mail, to the electronic mail address most recently provided to such party or such other electronic mail address as may be designated in writing by such party.

11.            Construction. THIS NOTE SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF NEW YORK, WITHOUT REGARD TO CONFLICT OF LAW PROVISIONS THEREOF.

3

12.            Severability. Any provision contained in this Note which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

13.            Trust Waiver. Notwithstanding anything herein to the contrary, the Payee hereby waives any and all right, title, interest or claim of any kind (“Claim”) in or to any distribution of or from the trust account (the “Trust Account”) in which the proceeds of the initial public offering (the “IPO”) conducted by the Maker and certain of the proceeds of the sale of the warrants issued in a private placement in connection with the consummation of the IPO are deposited, as described in greater detail in the registration statement and prospectus filed with the Securities and Exchange Commission in connection with the IPO, and hereby agrees not to seek recourse, reimbursement, payment or satisfaction for any Claim against the trust account for any reason whatsoever; provided, however, that if the Maker completes an Initial Business Combination, the Maker shall repay the principal balance of this Note, which may be out of the proceeds released to the Maker from the Trust Account.

14.            Amendment; Waiver. Any amendment hereto or waiver of any provision hereof may be made with, and only with, the written consent of the Maker and the Payee.

9

provided, however, as to any particular Registrable Securities, such securities shall cease to be Registrable Securities when: (i) a registration statement with respect to the sale of such securities shall have become effective under the Securities Act and such securities shall have been sold, transferred, disposed of or exchanged in accordance with such Registration Statement; (ii) such securities shall have been otherwise transferred, new certificates for such securities not bearing a legend restricting further transfer shall have been delivered by the Company and subsequent public distribution of such securities shall not require registration under the Securities Act; (iii) such securities shall have ceased to be outstanding; (iv) such securities have been sold to, or through, a broker, dealer or underwriter in a public distribution or other public securities transaction; or (v) such securities become eligible for resale without volume or manner-of-sale restrictions and without current public information pursuant to Rule 144 promulgated by the SEC pursuant to the Securities Act.”

3.7.            Shelf Registration. The following shall be inserted as a new Section 3.5A of the YSB Shareholders Agreement:

“3.5A Shelf Registration.

(a) Filing. The Company shall file within 20 days of the Second Merger Effective Time or within 60 days of the Second Merger Effective Time if the Company is required to include therein additional financial information that is not included in the Form F-4 at the time of the Second Merger Effective Time, and use commercially reasonable efforts to cause to be declared effective as soon as practicable thereafter within 90 calendar days following the Second Merger Effective Time, but if the SEC notifies the Company that the Shelf will not be “reviewed” or will not be subject to further review, such effectiveness date shall be no later than the 10th business day after the date the Company is notified (orally or in writing, whichever is earlier) by the SEC that the Registration Statement will not be “reviewed” or will not be subject to further review, a Registration Statement for a Shelf Registration on Form F-1 or Form S-1, as applicable (the “Form F-1 Shelf”) or, if the Company is eligible to use a Registration Statement on Form F-3 or Form S-3, a Shelf Registration on Form F-3 or Form S-3, as applicable (the “Form F-3 Shelf”, together with the Form F-1 Shelf, the “Shelf”), in each case, covering the resale of all the Registrable Securities (determined as of two business days prior to such filing) on a delayed or continuous basis; provided, however, that the Company’s obligations to include the Registrable Securities held by a holder of Registrable Securities (the “Holder”) in the Shelf are contingent upon such Holder furnishing in writing to the Company such information regarding the Holder, the securities of the Company held by the Holder and the intended method of disposition of the Registrable Securities as shall be reasonably requested by the Company to effect the registration of the Registrable Securities, and the Holder shall execute such documents in connection with such registration as the Company may reasonably request that are customary of a selling shareholder in similar situations. Such Shelf shall provide for the resale of the Registrable Securities included therein pursuant to any method or combination of methods legally available to, and requested by, any Holder named therein. The Company shall maintain a Shelf in accordance with the terms hereof, and shall prepare and file with the SEC such amendments, including post-effective amendments, and supplements as may be necessary to keep a Shelf continuously effective, available for use and in compliance with the provisions of the Securities Act until such time as there are no longer any Registrable Securities in such Shelf. In the event the Company files a Form F-1 Shelf, the Company shall use its commercially reasonable efforts to convert the Form F-1 Shelf (and any Subsequent Shelf Registration) to a Form F-3 Shelf as soon as practicable after the Company is eligible to use Form F-3. References to Section 3.5 in Section 3.10 of the YSB Shareholders Agreement shall exclude this Section 3.5A.

10

(b)

Subsequent Shelf Registration. If any Shelf ceases to be effective under the Securities Act for any reason at any time while Registrable Securities are still outstanding, the Company shall use its commercially reasonable efforts to as promptly as is reasonably practicable cause such Shelf to again become effective under the Securities Act (including obtaining the prompt withdrawal of any order suspending the effectiveness of such Shelf), and shall use its commercially reasonable efforts to as promptly as is reasonably practicable amend such Shelf in a manner reasonably expected to result in the withdrawal of any order suspending the effectiveness of such Shelf or file an additional registration statement as a Shelf (a “Subsequent Shelf Registration”) registering the resale of all Registrable Securities (determined as of two business days prior to such filing), and pursuant to any method or combination of methods legally available to, and requested by, any Holder named therein. If a Subsequent Shelf Registration is filed, the Company shall use its commercially reasonable efforts to (i) cause such Subsequent Shelf Registration to become effective under the Securities Act as promptly as is reasonably practicable after the filing thereof (it being agreed that the Subsequent Shelf Registration shall be an automatic shelf registration statement (as defined in Rule 405 promulgated under the Securities Act) if the Company becomes a well-known seasoned issuer (as defined in Rule 405 promulgated under the Securities Act) at the most recent applicable eligibility determination date), and (ii) keep such Subsequent Shelf Registration continuously effective, available for use and in compliance with the provisions of the Securities Act until such time as there are no longer any Registrable Securities included in such Subsequent Shelf Registration. Any such Subsequent Shelf Registration shall be on Form F-3 or Form S-3, as applicable, to the extent that the Company is eligible to use such form. Otherwise, such Subsequent Shelf Registration shall be on another appropriate form.

(c)

Underwriting. If the Holders of Registrable Securities requesting registration under this Section 3.5A intend to distribute the Registrable Securities covered by their request by means of an underwriting, the provisions of Section 3.3(b) shall apply to such registration.”

3.8.            Assignment. Section 10.1 of the YSB Shareholders Agreement is amended in its entirety and replaced as follows:

From:

“10.1 Assignment. Notwithstanding anything herein to the contrary, all rights and obligations of the Preferred Holders (in their capacity as a Preferred Holder or otherwise) may be assigned to any Person to which the Preferred Holders transfer their Preferred Shares in accordance with this Agreement; provided, however, that no party, other than the Preferred Holders and its Affiliates, may be assigned any of the foregoing rights unless the Company is given written notice by the assigning party stating the name and address of the assignee and identifying the securities of the Company as to which the rights in question are being assigned.”

To:

“10.1 Assignment. Except as otherwise provided in this Agreement, the terms and conditions of this Agreement shall inure to the benefit of and be binding upon the respective permitted successors and assigns of the parties (including transferees of any Registrable Securities). Nothing in this Agreement, express or implied, is intended to confer upon any party other than the parties hereto or their respective successors and assigns any rights, remedies, obligations, or liabilities under or by reason of this Agreement, except as expressly provided in this Agreement.”

11

3.9.            Amendment and Modification. Section 10.2 of the YSB Shareholders Agreement is amended by adding the following bolded and underlined text:

“10.2 Amendment of Rights. Any provision in this Agreement may be amended and the observance thereof may be waived (either generally or in a particular instance and either retroactively or prospectively), only by the written consent of (i) as to the Company, only by the Company; (ii) as to the Series A Holders, only by the Majority Series A Holders (and the relevant holders of the Ordinary Shares which the Series A Preferred Shares have been converted into), provided, however, that any Series A Holder may waive any of its own rights hereunder without obtaining the consent of any other Series A Holders, provided further, that any amendment or waiver that effects any Series A Holder in a disproportionate and adverse manner than the effect of such amendment or waiver on any other Series A Holders shall require the written consent of the holder so disproportionately and adversely affected; (iii) as to the Series B Holders, only by the Majority Series B Holders (and relevant holders of the Ordinary Shares which the Series B Preferred Shares have been converted into), provided, however, that any Series B Holder may waive any of its own rights hereunder without obtaining the consent of any other Series B Holders; provided further, that any amendment or waiver that affects any Series B Holder in a disproportionate and adverse manner than the effect of such amendment or waiver on any other Series B Holders shall require the written consent of the holder so disproportionately and adversely affected, and (iv) as to the Ordinary Holders, by person or entities holding at least a majority of the outstanding Ordinary Shares; provided, however, that any Ordinary Holder may waive any of its own rights hereunder without obtaining the consent of any other Ordinary Holders. Any amendment or waiver effected in accordance with this Section 10 shall be binding upon the Company, the Series A Holders, the Series B Holders, the Ordinary Holders and their respective permitted transferees. Notwithstanding the foregoing and anything to the contrary contained herein, (i) only upon the prior written consent of the Company and the Holders of at least a majority of the Registrable Securities at the time in question, compliance with any of the provisions, covenants and conditions set forth in Section 3 (Registration Rights) of this Agreement may be waived, or any of such provisions, covenants or conditions may be amended or modified; provided, however, that any amendment or modification to Section 3 (Registration Rights) of this Agreement that would have a disproportionately adverse effect on any party’s rights hereunder in any material respect shall require the prior written consent of such party, and (ii) no amendment or modification shall be made to Section 2A (Sponsor Board Representation) without Sponsor’s prior written consent.”

3.10.            Termination Upon First Merger. The following shall be inserted as a new Section 12.14 of the YSB Shareholders Agreement:

“12.14 Termination upon First Merger. Section 1 (Information Rights and Inspection Rights), Section 2 (Board Representation), Section 4 (Right of Participation), Section 5 (Transfer Restrictions), Section 6 (Confidentiality and Non-Disclosure), Section 7 (Protective Provisions), Section 8A (Conversion Rights), Section 9A (Liquidation Preference), Section 9B (Redemption) and Section 11 (Other Undertakings of the Company and the Founders), except for Section 11.5 (Use of Preferred Holders’ Name or Logo), of this Agreement shall be automatically terminated effective as of the First Merger Effective Time, and thereupon shall be of no further force or effect, without any further action on the part of any of the Shareholders or the Company, and neither the Company, the Shareholders, nor any of their respective affiliates or subsidiaries shall have any further rights, duties, liabilities or obligations thereunder and each Shareholder and the Company hereby releases in full any and all claims with respect thereto with effect on and from the First Merger Effective Time.”

3.11.            Additional Parties. The following shall be inserted as a new Section 12.15 of the YSB Shareholders Agreement and the Exhibit A referred to therein shall be in the form of Annex I hereto:

“12.15 Deed of Adherence. Each Shareholder and its permitted transferees (if not already a party to this Agreement) may, upon execution and delivery to the Company of a Deed of Adherence substantially in the form attached hereto as Exhibit A, become a party to this Agreement, as if it had been a Party to this Agreement as of the date thereof and shall be subject to all of the rights, obligations, and restrictions described in this Agreement.”

12

3.12.            Miscellaneous. Each of Section 3.1, Section 3.14 and Section 3.15 of the YSB Shareholders Agreement is deleted in its entirety and replaced as follows, respectively:

From:

“3.1          Applicability of Rights. The Preferred Holders shall be entitled to the following rights with respect to any potential public offering of the Company’s Ordinary Shares in the United States and shall be entitled to reasonably analogous or equivalent rights with respect to any other offering of the Company’s securities in any other jurisdiction in which the Company undertakes to publicly offer or list such securities for trading on a recognized securities exchange.”

“3.14        Qualified IPO. The Company and the Founder shall use their best efforts to complete, or cause to complete, a Qualified IPO prior to January 28, 2024.”

“3.15        Preferred Holders’ Right to Sell Shares in a Public Offering. Preferred Holders hereby agree not to transfer or sell their shares in the IPO of the Company, unless otherwise agreed on by the Company.”

To:

“3.1          [Intentionally Omitted.]”

“3.14        [Intentionally Omitted.]”

“3.15        [Intentionally Omitted.]”

Article IV

Additional Agreements of the Parties

4.1.            Sponsor Share Forfeiture and Conversion. Sponsor hereby agrees that immediately prior to the First Merger Effective Time, Sponsor shall surrender to SPAC an aggregate of 1,446,525 SPAC Class B Ordinary Shares for cancellation at no cost (the “Sponsor Share Forfeiture”). Immediately following the completion of the Sponsor Share Forfeiture and before the First Merger Effective Time, Sponsor will hold an aggregate of 3,853,475 SPAC Class B Ordinary Shares, and all such shares will be exchanged for ordinary shares of the Company, par value $0.00002 per share, on a one-for-one basis in connection with the First Merger (the “Sponsor Share Conversion”). Notwithstanding the foregoing, if (i) after completion of the Sponsor Share Forfeiture, the First Merger does not occur and the Business Combination Agreement is terminated, or (ii) after completion of the First Merger, the Second Merger does not occur and the Business Combination Agreement is terminated, each of SPAC, Sponsor and the Company shall take all such actions that are necessary, proper or advisable under applicable Laws such that Sponsor shall, to the fullest extent possible, be returned to the position in which Sponsor would have been, and would be entitled to all rights and benefits that Sponsor would have had, as if the Sponsor Share Forfeiture and the Sponsor Share Conversion, as the case may be, had not occurred.

4.2.            Sponsor Affiliate Agreements. Each of Sponsor and SPAC hereby agree that from the date hereof until the termination of this Agreement, none of them shall, or shall agree to, amend, modify or vary that certain letter agreement dated June 8, 2021 by and among the Sponsor, SPAC and other SPAC Shareholders, except as otherwise provided for under this Agreement, the Business Combination Agreement or any other Transaction Documents.

4.3.            Existing Shareholder Rights. Each of the YSB Shareholders and the Company hereby agrees that, (i) after the First Merger Effective Time, except as set forth in the YSB Shareholders Agreements and the Amended Company Charter, any rights under any other agreement providing for right of first refusal, right of first offer, participation rights, redemption rights, put rights, purchase rights or other similar rights not generally available to the shareholders of the Company, if any, shall be automatically terminated effective as of the First Merger Effective Time, and thereupon shall be of no further force or effect, without any further action on the part of any of the YSB Shareholders or the Company, and neither the Company, the YSB Shareholders, nor any of their respective affiliates or subsidiaries shall have any further rights, duties, liabilities or obligations thereunder and (ii) from the date hereof until the termination of this Agreement, none of them shall, or shall agree to, amend, modify or vary the YSB Shareholders Agreement without Sponsor’s prior written consent, except as otherwise provided for under this Agreement, the Business Combination Agreement or any other Transaction Documents. For the avoidance of doubt, after the effectiveness of the YSB SHA Amendments, none of the shareholders of the Company will have redemption rights that are not generally available to the shareholders of the Company.

13

4.4.            Termination of Prior SPAC Agreement. Each of SPAC, Sponsor and other SPAC Insiders hereby agrees that the Prior SPAC Agreement shall terminate as of the First Merger Effective Time, and thereafter shall be of no further force and effect.

4.5.            Non-Recourse. This Agreement may only be enforced against, and any claim or cause of action based upon, arising out of, or related to this Agreement or the transactions contemplated hereby may only be brought against, the entities that are expressly named as parties hereto and then only with respect to the specific obligations set forth herein with respect to such party. Except to the extent a party hereto (and then only to the extent of the specific obligations undertaken by such party in this Agreement), or its successor or transferee, (a) no past, present or future director, officer, employee, incorporator, member, partner, shareholder, stockholder, Affiliate, agent, attorney, advisor or other Representative of any party hereto and (b) no past, present or future director, officer, employee, incorporator, member, partner, shareholder, stockholder, Affiliate, agent, attorney, advisor or other representative of any of the foregoing shall have any liability (whether in contract, tort, equity or otherwise) for any one or more of the representations, warranties, covenants, agreements or other obligations or liabilities of any of the SPAC, the Company, or the Shareholders under this Agreement or for any claim based on, arising out of, or related to this Agreement or the transactions contemplated hereby.

4.6.            Additional Matters. Each Shareholder shall, from time to time, refrain from exercising any veto right, consent right or similar right (whether under the Company Charter or the Cayman Act) which would impede, disrupt, prevent or otherwise adversely affect the consummation of the Mergers or any other Transaction.

4.7.            Fiduciary Duties. Notwithstanding anything in this Agreement to the contrary, nothing herein will be construed to limit or affect any action or inaction by any Shareholder or SPAC Insider serving as a director, officer, employee or fiduciary of SPAC or the Company (as the case may be).

4.8.            Sponsor Reimbursement. If the SPAC Transaction Expenses or SPAC’s operating expenses exceed the applicable maximum amounts agreed between the Company and SPAC in accordance with section 11.6 of the Business Combination Agreement, Sponsor shall, at the Closing, reimburse SPAC or the Company for the expenses in excess of such mutually agreed amounts. Sponsor may elect to satisfy its foregoing reimbursement obligation (if any) by (i) cash payment or (ii) cancellation of amounts then outstanding under the Working Capital Loan.

Article V

General Provisions

This Agreement and the rights, duties and obligations of the Company hereunder may not be assigned or delegated by the Company in whole or in part.

This Agreement shall not confer any rights or benefits on any persons that are not parties hereto, other than as expressly set forth in this Agreement (including Section 4.5 hereof).

14

5.3.            Severability. The invalidity or unenforceability of any specific provision of this Agreement shall not invalidate or render unenforceable any of its other provisions. The parties hereto further agree that if any provision contained in this Agreement is, to any extent, held invalid or unenforceable in any respect under the laws governing this Agreement, they shall take any actions necessary to render the remaining provisions of this Agreement valid and enforceable to the fullest extent permitted by law and, to the extent necessary, shall amend or otherwise modify this Agreement to replace any provision contained in this Agreement that is held invalid or unenforceable with a valid and enforceable provision giving effect to the intent of the parties hereto.

5.4.            Entire Agreement. This Agreement (together with the Business Combination Agreement, the YSB Shareholders Agreement, and including all agreements entered into pursuant hereto or thereto or referenced herein or therein and all certificates and instruments delivered pursuant hereto and thereto) set forth the entire understanding of the parties with respect to the subject matter hereof and supersede all other prior and contemporaneous agreements and understandings between the parties, whether oral or written, with respect to such subject matter.

5.5.            Governing Law; Venue. Notwithstanding the place where this Agreement may be executed by any of the parties hereto, the parties expressly agree that this Agreement shall be governed by and construed under the Laws of the State of New York as applied to agreements among New York residents entered into and to be performed entirely within New York, without regard to the conflict of law provisions of such jurisdiction and the venue for any action taken with respect to this Agreement shall be any state or federal court in the State of New York.

5.6.            WAIVER OF TRIAL BY JURY. EACH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES THE RIGHT TO A TRIAL BY JURY IN ANY ACTION, SUIT, COUNTERCLAIM OR OTHER PROCEEDING (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF, CONNECTED WITH OR RELATING TO THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREBY, OR THE ACTIONS OF THE SPONSOR IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE OR ENFORCEMENT HEREOF.

5.7.            Construction. The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rule of strict construction will be applied against any party.

The headings, subheadings and captions contained in this Agreement are included for convenience of reference only, and in no way define, limit or describe the scope of this Agreement or the intent of any provision hereof.

5.8.            Amendments and Modifications. Only upon the prior written consent of (i) the Company, (ii) SPAC, (iii) Sponsor, (iv) YSB Shareholders holding at least fifty percent (50%) of the then outstanding YSB Ordinary Shares, (v) the Majority Series A Holders (as defined in the YSB Shareholders Agreement) and (vi) the Majority Series B Holders (as defined in the YSB Shareholders Agreement) (collectively, the “Consent Parties”), compliance with any of the provisions, covenants and conditions set forth in this Agreement may be waived, or any of such provisions, covenants or conditions may be amended or modified; provided, however, that notwithstanding the foregoing, any amendment or modification to this Agreement that would have a disproportionately adverse effect on any party’s rights hereunder in any material respect shall require the prior written consent of such party.

5.9.            Counterparts. This Agreement may be executed in multiple counterparts (including by electronic means), each of which shall be deemed an original, and all of which together shall constitute the same instrument, but only one of which need be produced.

15

Whereas, on the date of this Agreement, SPAC, the Company, Oceanview Bioscience Acquisition Co., Ltd., a Cayman Islands exempted company (“Merger Sub I”), and Hudson Biomedical Group Co., Ltd., a Cayman Islands exempted company (“Merger Sub II”), entered into a business combination agreement (as amended, modified or supplemented from time to time, the “Business Combination Agreement”);

Whereas, all of the Warrants are governed by the Existing Warrant Agreement;

Whereas, pursuant to the Business Combination Agreement, Merger Sub I will merge with and into SPAC, with SPAC surviving such merger as a wholly-owned subsidiary of the Company (the “First Merger”, and the effective time of the First Merger is hereinafter referred to as the “First Merger Effective Time”), and as a result of the First Merger, the holders of Ordinary Shares of SPAC shall become holders of ordinary shares of par value US$0.00002 each of the Company (“Company Ordinary Shares”), and SPAC, as the surviving company in the First Merger, will then merge with and into Merger Sub II (the “Second Merger”), with Merger Sub II being the surviving entity and a wholly-owned subsidiary of the Company;

YS Group’s business operations are subject to various PRC laws and regulations, the interpretation and enforcement of which involve significant uncertainties as the PRC legal system is evolving rapidly . PRC regulations relating to offshore investment activities by PRC residents may subject YS Biopharma’s PRC resident shareholders, beneficial owners and PRC subsidiaries to liability or penalties, limit their ability to inject capital into its PRC subsidiaries, limit its PRC subsidiaries’ ability to increase their registered capital or distribute profits to YS Group or otherwise adversely affect us . YS Group’s PRC subsidiaries are subject to restrictions on paying dividends or making other payments to its offshore holding companies, including the YS Biopharma, which may restrict their ability to satisfy liquidity requirements . Fluctuations in exchange rates could have a material and adverse effect on the value of your investment and YS Biopharma’s results of operations . PRC regulation of loans to and direct investment in PRC entities by offshore holding companies and governmental control of currency conversion may restrict or delay YS Biopharma or YS Biopharma from using the offshore proceeds to make loans or additional capital contributions to its PRC subsidiaries, which could adversely affect its liquidity and ability to fund and expand its business . Foreign exchange controls may limit YS Group’s ability to effectively utilize its revenues and proceeds generated or financed outside China and adversely affect the value of your investment . The M&A Rules and certain other PRC regulations could make it more difficult for YS Group to pursue growth through acquisitions in China . Failure to comply with PRC regulations regarding the registration requirements for employee stock ownership plans or share option plans may subject the PRC plan participants or YS Biopharma to fines and other legal or administrative sanctions . Your ability to effect service of legal process, enforce judgments or bring actions against YS Biopharma, YS Biopharma, Summit Healthcare or certain of their officers and directors outside the U . S . will be limited and addition costs may be required . As an exempted company incorporated in the Cayman Islands, the YS Biopharma is permitted to adopt certain home country practices in relation to corporate governance matters that differ significantly from Nasdaq corporate governance listing standards ; these practices may afford less protection to the investors than they would enjoy if the YS Biopharma complied fully with Nasdaq corporate governance listing standards . You may face difficulties in protecting your interests, and your ability to protect your rights through U . S . courts may be limited, because the YS Biopharma is incorporated under the law of the Cayman Islands, the YS Biopharma conducts substantially all of its operations and a majority of its directors and executive officers reside outside of the United States . Inflation in China and increase in labor costs could negatively affect the profitability and growth of YS Group . YS Biopharma may be deemed to be a PRC tax resident under the EIT Law following the consummation of the Business Combination, and as a result, their global income could be subject to PRC withholding tax and enterprise income tax . YS Group and YS Biopharma’s Shareholders face uncertainties with respect to Business Combination and other indirect transfers of equity interests in PRC resident enterprises . Dividends payable to YS Biopharma’s foreign investors and gains on the sale of YS Biopharma’s securities by foreign investors may become subject to PRC tax . 8

Risk Factors 㸦 Continued 㸧 YS Biopharma faces regulatory uncertainties in China that could restrict its ability to grant share incentive awards to its employees or consultants who are PRC citizens . It may be difficult for overseas regulators to conduct investigation or collect evidence within China . If the custodians or authorized users of YS Group’s controlling non - tangible assets, including chops and seals, fail to fulfill their responsibilities, or misappropriate or misuse these assets, its business and operations may be materially and adversely affected . Risks Related to Ownership of the YS Biopharma Ordinary Shares The price of the YS Biopharma Ordinary Shares may be volatile, and the value of the YS Biopharma Ordinary Shares may decline . A market for YS Biopharma’s securities may not develop or be sustained, which would adversely affect the liquidity and price of Summit Healthcare’s securities . Provisions in the Amended YS Biopharma Articles could discourage, delay or prevent a change of control of YS Biopharma and may affect the trading price of the YS Biopharma Ordinary Shares . The Amended YS Biopharma Articles will provide that the courts of the Cayman Islands will be the exclusive forums for certain disputes between YS Biopharma and its shareholders, which could limit YS Biopharma’s shareholders’ ability to obtain a favorable judicial forum for complaints against YS Biopharma or its directors, officers or employees . The warrant agreement relating to the YS Biopharma Warrants will provide that YS Biopharma agrees that any action, proceeding or claim against YS Biopharma arising out of or relating in any way to such agreement will be brought and enforced in the courts of the State of New York or the United States District Court for the Southern District of New York, and that it irrevocably submits to such jurisdiction, which will be the exclusive forum for any such action, proceeding or claim . This exclusive forum provision could limit the ability of holders of the YS Biopharma Warrants to obtain what they believe to be a favorable judicial forum for disputes related to such agreement . If YS Biopharma does not meet the expectations of equity research analysts, if they do not publish research or reports about YS Biopharma’s business or if they issue unfavorable commentary or downgrade the YS Biopharma Ordinary Shares, the price of the YS Biopharma Ordinary Shares could decline . YS Biopharma’s issuance of additional share capital in connection with financings, acquisitions, investments, YS Biopharma’s equity incentive plans or otherwise will dilute all other shareholders . YS Biopharma does not intend to pay dividends for the foreseeable future and, as a result, your ability to achieve a return on your investment will depend on appreciation in the price of the YS Biopharma Ordinary Shares . YS Biopharma will be an emerging growth company and may take advantage of certain reduced reporting requirements . YS Biopharma will be a foreign private issuer within the meaning of the rules under the Exchange Act, and as such YS Biopharma will be exempt from certain provisions applicable to U . S . domestic public companies . YS Biopharma may lose its foreign private issuer status in the future, which could result in significant additional costs and expenses . As an exempted company incorporated in the Cayman Islands, YS Biopharma is permitted to adopt certain home country practices in relation to corporate governance matters that differ significantly from Nasdaq’s corporate governance requirements ; these practices may afford less protection to shareholders . If YS Biopharma opts to rely on such exemptions in the future, such decision might afford less protection to holders of YS Biopharma’s ordinary shares . As a result of being a public company, YS Biopharma will be obligated to develop and maintain proper and effective internal controls over financial reporting, and any failure to maintain the adequacy of these internal controls may adversely affect investor confidence in YS Biopharma and, as a result, the value of the YS Biopharma Ordinary Shares . As a result of YS Biopharma’s plans to expand operations, including to jurisdictions in which the tax laws may not be favorable, YS Biopharma’s tax rate may fluctuate, its tax obligations may become significantly more complex and subject to greater risk of examination by taxing authorities or YS Biopharma may be subject to future changes in tax law, the impacts of which could adversely affect YS Biopharma’s after - tax profitability and financial results . If YS Biopharma or any of its subsidiaries is treated as a “controlled foreign corporation” for U . S . federal income tax purposes, certain U . S . Holders may be subject to adverse U . S . federal income tax consequences . If YS Biopharma is or becomes a “passive foreign investment company” for U . S . federal income tax purposes, U . S . Holders may be subject to adverse U . S . federal income tax consequences . Risks Relating to Summit Healthcare and the Business Combination The process of taking a company public by means of a business combination with a special purpose acquisition company is different from taking a company public through a traditional initial public offering and may create risks for our unaffiliated investors . Summit’s current directors and officers and their affiliates have interests that are different from, or in addition to (and which may conflict with), the interests of its shareholders, and therefore potential conflicts of interest exist in recommending that shareholders vote in favor of approval of the Business Combination . Such conflicts of interests include that the Sponsor as well as Summit’s directors and officers are expected to lose their entire investment in Summit if the Business Combination is not completed . 9

10 Risk Factors 㸦 Continued 㸧 The exercise of Summit’s directors’ discretion in agreeing to changes or waivers in the terms of the Business Combination may result in a conflict of interest when determining whether such changes to the terms of the Business Combination or waivers of conditions are appropriate and in Summit’s best interest . We may be forced to close the Business Combination even if we determine it is no longer in Summit shareholders’ best interest . The Initial Shareholders agreed to vote in favor of the Business Combination, regardless of how Summit Public Shareholders vote . Summit is dependent upon its directors and officers and their loss could adversely affect Summit’s ability to complete the Business Combination . Summit’s directors and officers will allocate their time to other businesses, thereby causing conflicts of interest in their determination as to how much time to devote to Summit’s affairs . This conflict of interest could have a negative impact on Summit’s ability to complete the Business Combination . Past performance by Mr . Bo Tan, Mr . Ken Poon or entities affiliated with Summit or its Sponsor, including its management team, may not be indicative of future performance of an investment in YS Biopharma . Sponsor, Summit’s directors, officers and their affiliates may elect to purchase shares or warrants from Summit Public Shareholders, which may influence a vote on the Business Combination and reduce Summit’s public “float . ” Shareholder litigation could prevent or delay the closing of the Business Combination or otherwise negatively impact business, operating results and financial condition . The COVID - 19 pandemic triggered an economic crisis which may delay or prevent the consummation of the Business Combination . Delays in completing the Business Combination may substantially reduce the expected benefits of the Business Combination . Summit may not have sufficient funds to consummate the Business Combination . If Summit is unable to complete this Business Combination, or another business combination, within the prescribed time frame, Summit would cease all operations except for the purpose of winding up and redeem all the Summit Public Shares and liquidate . If, before distributing the proceeds in the Trust Account to Summit Public Shareholders, Summit files a bankruptcy or insolvency petition or an involuntary bankruptcy or insolvency petition is filed against it that is not dismissed, the claims of creditors in such proceeding may have priority over the claims of its shareholders, even for funds in the Trust Account and the per - share amount that would otherwise be received by its shareholders in connection with its liquidation may be reduced . If the Adjournment Proposal is not approved, and an insufficient number of votes have been obtained to authorize the consummation of the Business Combination, the Summit Board will not have the ability to adjourn the Extraordinary General Meeting to a later date in order to solicit further votes, and, therefore, the Business Combination will not be approved . If third parties bring claims against Summit, the proceeds held in the Trust Account could be reduced and the per - share redemption amount received by shareholders may be less than $ 10 . 00 per share . If, after Summit distributes the proceeds in the Trust Account to Summit Public Shareholders, Summit files a bankruptcy or insolvency petition or an involuntary bankruptcy or insolvency petition is filed against it that is not dismissed, a bankruptcy or insolvency court may seek to recover such proceeds, and the members of the Summit Board may be viewed as having breached their fiduciary duties to its creditors, thereby exposing the members of its board of directors and Summit to claims of punitive damages . The Business Combination may be completed even though material adverse effects may result from the announcement of the Business Combination, industry - wide changes and other causes . Subsequent to the completion of the Business Combination, YS Biopharma may be required to subsequently take write - downs or write - offs, restructure its operations, or incur unanticipated losses, impairment or other charges or liabilities that could have a significant negative effect on its financial condition, results of operations and the price of YS Biopharma Securities, which could cause Summit shareholders to lose some or all of their investment . During the interim period, Summit is prohibited from entering into certain transactions that might otherwise be beneficial to Summit or its shareholders . The Business Combination remains subject to conditions that Summit cannot control and if such conditions are not satisfied or waived, the Business Combination may not be consummated . A shareholder who has exercised Dissent Rights and followed the dissent procedure prescribed by the Cayman Islands Companies Act may subsequently lose their Dissent Rights following the Extraordinary General Meeting, including where completion of the Merger is delayed in order to invoke the exemption under Section 239 of the Cayman Islands Companies Act, in which event such dissenting shareholder would not receive cash for their Summit Shares and instead would only be entitled to receive the merger consideration and would become a shareholder of YS Biopharma upon consummation of the Business Combination . Summit shareholders may have limited remedies if their shares suffer a reduction in value following the Business Combination, and because Summit (and also YS Biopharma, the surviving company) is incorporated under the laws of the Cayman Islands, shareholders may face difficulties in protecting their interests, and a shareholder’s ability to protect its rights through the U . S . federal courts may be limited . Summit Warrants are accounted for as liabilities and the changes in value of Summit Warrants could have a material effect on Summit’s financial results .

Risk Factors 㸦 Continued 㸧 Risks Relating to U . S . Taxation If the Merger does not qualify as a “reorganization” under section 368 (a) of the Code, then the Merger will generally be taxable to U . S . Holders . Risks Relating to Redemption of Summit Public Shares You will not have any rights or interests in funds from the Trust Account, except under certain limited circumstances . To liquidate your investment, therefore, you may be forced to redeem or sell your Summit Public Shares or Summit Public Warrants, potentially at a loss . Summit Public Shareholders who wish to redeem their Summit Public Shares for a pro rata portion of the Trust Account must comply with specific requirements for redemption, which may make it difficult for them to exercise their redemption rights prior to the deadline . If Summit Public Shareholders fail to comply with the redemption requirements specified in this proxy statement/prospectus, they will not be entitled to redeem their Summit Public Shares for a pro rata portion of the funds held in the Trust Account . Summit does not have a specified maximum redemption threshold . The absence of such a redemption threshold may make it possible for Summit to complete a business combination with which a substantial majority of its shareholders do not agree . The grant and future exercise of registration rights may adversely affect the market price of YS Biopharma Ordinary Shares upon consummation of the Business Combination . If you or a “group” of shareholders of which you are a part are deemed to hold an aggregate of more than 15 % of the Summit Public Shares issued in the IPO, you (or, if a member of such a group, all of the members of such group in the aggregate) will lose the ability to redeem all such shares in excess of 15 % of the Summit Public Shares issued in the IPO . There is no guarantee that a shareholder’s decision whether to redeem its Summit Public Shares for a pro rata portion of the Trust Account will put the shareholder in a better future economic position . 11
