Prior to the initial public offering (the “IPO”) of the SPAC, SCS Sponsor III LLC (“SCS Sponsor III”) purchased 6,250,000 Class B ordinary shares, par value $0.0001, of the SPAC (“SPAC Class B ordinary shares”), after giving effect to certain share capitalizations and forfeitures in connection with the IPO, for an aggregate purchase price of $25,000. Prior to the IPO, SCS Sponsor III transferred 30,000 of its 6,250,000 SPAC Class B ordinary shares to an independent director of the SPAC. In connection with the closing of the IPO, SCS Sponsor III purchased 640,000 Class A ordinary shares (the “IPO Private Placement Shares”), par value $0.0001 per share, of the SPAC (“SPAC Class A ordinary shares”) for an aggregate purchase price of $6,400,000.

SCS Sponsor III obtained the funds to purchase the foregoing securities from its working capital.

On July 11, 2022, in connection with the consummation (the “Closing”) of the business combination (the “Business Combination”) contemplated by that certain Business Combination Agreement, dated as of January 18, 2022, by and between the SPAC and ProKidney LP, a limited partnership organized under the laws of Ireland, acting through its general partner ProKidney GP Limited, a private limited company incorporated under the laws of Ireland, (i) each outstanding SPAC Class B ordinary share automatically converted into an Issuer Class A ordinary share on a one-for-one basis for no additional consideration and (ii) each outstanding SPAC Class A ordinary share became an Issuer Class A ordinary shares on a one-for-one basis for no additional consideration.

Concurrently with the Closing, SCS Sponsor III distributed for no consideration the 6,860,000 Issuer Class A ordinary shares it held of record immediately after the Closing to its members pro rata in accordance with their respective interests (the “Sponsor Distribution”). SC Master Holdings received 3,773,000 Issuer Class A ordinary shares in the Sponsor Distribution. SC Master Holdings is the holder of record of such 3,773,000 Issuer Class A ordinary shares.

Also in connection with the Business Combination, the SPAC effected a private placement (the “PIPE Financing”) that was contingent upon the substantially concurrent consummation of the Business Combination and which occurred on July 11, 2022, the date of the Closing (the “Closing Date”). Pursuant to a subscription agreement (the “Subscription Agreement”) entered in connection with the PIPE Financing, SC Master Holdings subscribed for 12,500,000 Issuer Class A ordinary shares for a purchase price of $10.00 per share. Of the 12,500,000 Issuer Class A ordinary shares subscribed for by SC Master Holdings, (i) SC PIPE Holdings purchased 9,500,000 Issuer Class A ordinary shares for an aggregate purchase price of $95,000,000 pursuant to the Subscription Agreement and (ii) the Trust purchased 3,000,000 Issuer Class A ordinary shares for an aggregate purchase price of $30,000,000.

SC PIPE Holdings obtained the funds to purchase the foregoing securities from its working capital.

Upon delivery of written notice from (or on behalf of) SCS to the Investor (the “Closing Notice”) that SCS reasonably expects all conditions to the closing of the Transaction to be satisfied or waived on an expected Transaction Closing Date that is not less than five (5) business days from the date on which the Closing Notice is delivered to the Investor, the Investor shall deliver the Subscription Amount three (3) business days prior to the expected Closing Date by wire transfer of United States dollars in immediately available funds to the account(s) specified by SCS in the Closing Notice. On the Closing Date, SCS shall issue the Shares to the Investor and subsequently cause the Shares to be registered in book entry form in the name of the Investor on the SCS share register. For purposes of this Subscription Agreement, “business day” shall mean a day, other than a Saturday, Sunday or other day on which commercial banks in New York, New York or governmental authorities in the Cayman Islands are authorized or required by law to close. Prior to the Closing, Investor shall deliver to SCS a duly completed and executed Internal Revenue Service Form W-9 or appropriate Form W-8. In the event the Transaction Closing Date does not occur within two (2) business days after the Closing Date under this Subscription Agreement, the Subscription Amount will be returned to the Investor by wire transfer of U.S. dollars in immediately available funds to the account specified by the Investor, and any book-entries for the Shares shall be deemed repurchased and cancelled; provided that, unless this Subscription Agreement has been terminated pursuant to Section 9 hereof, such return of funds shall not terminate this Subscription Agreement or relieve the Investor of its obligation to purchase the Shares at the Closing, and the Investor shall remain obligated (i) to redeliver funds to SCS following SCS’s delivery to the Investor of a new Closing Notice and (ii) to consummate the Closing substantially concurrently with the consummation of the Transaction.

[In place of the above, the below will be included for mutual funds and other certain regulated investors:

The closing of the sale of the Shares contemplated hereby (the “Closing”) shall occur on the anticipated closing date of the Transaction (the “Transaction Closing Date”) as specified in the Closing Notice (as defined below) (the “Closing Date”). Upon delivery of written notice from (or on behalf of) SCS to the Investor (the “Closing Notice”), that SCS reasonably expects all conditions to the closing of the Transaction to be satisfied or waived (in writing by any person who has the authority to make such waiver) on an expected Transaction Closing Date that is not less than five (5) business days from the date on which the Closing Notice is delivered to the Investor, the Investor shall deliver, subject to the conditions set forth in this Section 2, the Subscription Amount on the specified Closing Date by wire transfer of United States dollars in immediately available funds to the account(s) specified by SCS in the Closing Notice. On the Closing Date and prior to the release of its Subscription Amount by the Investor, SCS shall issue the Shares against payment of the Subscription Amount to the Investor and cause the Shares to be registered in book entry form in the name of the Investor on SCS’s share register and will provide to the Investor evidence of such issuance from SCS’s transfer agent. For purposes of this Subscription Agreement, “business day” shall mean a day, other than a Saturday, Sunday or other day on which commercial banks in New York, New York or governmental authorities in the Cayman Islands are authorized or required by law to close. Prior to the Closing upon request of SCS, Investor shall deliver to SCS a duly completed and executed Internal Revenue Service Form W-9 or appropriate Form W-8. In the event the Transaction Closing Date does not occur within two (2) business days after the expected Transaction Closing Date set forth in the Closing Notice, SCS shall promptly (but not later than two (2) business days thereafter) return the Subscription Amount to the Investor by wire transfer of U.S. dollars in immediately available funds to the account specified by the Investor, and any book-entries for the Shares shall be deemed repurchased and cancelled; provided that, unless this Subscription Agreement has been terminated pursuant to Section 9 hereof, such return of funds shall not terminate this Subscription Agreement or relieve the Investor of its obligation to purchase the Shares at the Closing, and the Investor shall remain obligated (i) to redeliver funds to SCS following SCS’s delivery to the Investor of a new Closing Notice and (ii) to consummate the Closing substantially concurrently with the consummation of the Transaction.]

3. Closing Conditions. The obligation of the parties hereto to consummate the purchase and sale of the Shares pursuant to this Subscription Agreement is subject to the satisfaction (or waiver in writing by each party entitled to the benefit thereof) of the following conditions: (a) there shall not be in force any injunction or order enjoining or prohibiting the issuance and sale of the Shares under this Subscription Agreement; (b) the terms of the Transaction Agreement (including the conditions thereto) shall not have been amended, and Section 8.3(d) of the Transaction Agreement shall not have been waived, in a manner that is materially adverse to the Investor (in its capacity as such); (c) the Shares (including the Shares acquired hereunder) have been approved for listing on the Nasdaq (as defined below), subject only to official notice of the issuance thereof; and (d)(i) solely with respect to the Investor’s obligation to close, the representations and warranties made by SCS, and (ii) solely with respect to SCS’s obligation to close, the representations and warranties made by the Investor, in each case, in this Subscription Agreement shall be true and correct in all material respects as of the Closing Date other than (x) those representations and warranties qualified by materiality, Material Adverse Effect (as defined below) or similar qualification, which shall be true and correct in all respects as of the Closing Date, and (y) those representations and warranties expressly made as of an earlier date, which shall be true and correct in all material respects (or, if qualified by materiality, Material Adverse Effect or similar qualification, all respects) as of such date, in each case without giving effect to the consummation of the Transactions.

4. Further Assurances. At the Closing, the parties hereto shall execute and deliver such additional documents and take such additional actions as the parties reasonably may deem to be practical and necessary in order to consummate the subscription as contemplated by this Subscription Agreement. For the avoidance of doubt, the Investor is not executing any lock-up or similar agreement with SCS.

5. SCS Representations and Warranties. SCS represents and warrants to the Investor that:

(a) SCS is an exempted company duly incorporated, validly existing and in good standing under the laws of the Cayman Islands (to the extent such concept exists in such jurisdiction). SCS has all power (corporate or otherwise) and authority to own, lease and operate its properties and conduct its business as presently conducted and to enter into, deliver and perform its obligations under this Subscription Agreement.

(b) As of the Closing Date, the Shares will be duly authorized and, when issued and delivered to the Investor against full payment therefor in accordance with the terms of this Subscription Agreement, the Shares will be validly issued, fully paid and non-assessable, free and clear of all liens or other encumbrances (other than those arising under this Agreement or applicable securities laws or those imposed by the Investor) and will not have been issued in violation of or subject to any preemptive or similar rights created under SCS’s organizational documents (as in effect at such time of issuance), under the laws of the Cayman Islands.

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

(d) The issuance and sale by SCS of the Shares pursuant to this Subscription Agreement will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition of any lien, charge or encumbrance upon any of the property or assets of SCS or any of its subsidiaries pursuant to the terms of: (i) any indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument to which SCS or any of its subsidiaries is a party or by which SCS or any of its subsidiaries is bound or to which any of the property or assets of SCS is subject that would reasonably be expected to have a material adverse effect on the business, financial condition or results of operations of SCS and its subsidiaries, taken as a whole (a “Material Adverse Effect”), or materially affect the validity of the Shares or the legal authority of SCS to comply in all material respects with its obligations under this Subscription Agreement; (ii) result in any violation of the provisions of the organizational documents of SCS; or (iii) result in any violation of any statute or any judgment, order, rule or regulation of any court or governmental agency or body, domestic or foreign, having jurisdiction over SCS or any of its properties that would reasonably be expected to have a Material Adverse Effect or materially affect the validity of the Shares or the legal authority of SCS to comply in all material respects with its obligations under this Subscription Agreement.

(e) As of their respective filing dates, all reports required to be filed by SCS with the U.S. Securities and Exchange Commission (the “SEC”) since June 29, 2021 (the “SEC Reports”) complied in all material respects with the applicable requirements of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations of the SEC promulgated thereunder, and none of the SEC Reports under the Exchange Act, when filed or, if amended, as of the date of such amendment with respect to those disclosures that are amended, contained any untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; provided that, with respect to any registration statement or any proxy statement/prospectus to be filed by SCS with respect to the Transaction or any other information relating to the Transaction or to the Company or any of its affiliates included in any SEC Report or filed as an exhibit thereto, the representation and warranty in this sentence is made to SCS’s knowledge. As of the date hereof, there are no material outstanding or unresolved comments in comment letters received by SCS from the staff of the Division of Corporation Finance of the SEC with respect to any of the SEC Reports. Notwithstanding the foregoing, this representation and warranty shall not apply to any statement or information in the SEC Reports that relates to changes to historical accounting policies of SCS in connection with any order, directive, guideline, comment or recommendation from the SEC or SCS’s auditors or accountants that is applicable to SCS or SCS’s auditor or accountants (collectively, the “Guidance”), nor shall any correction, amendment or restatement of SCS’s financial statements resulting from or relating to the Guidance result in a breach of any representation or warranty by SCS.

(f) SCS is not required to obtain any consent, waiver, authorization or order of, give any notice to, or make any filing or registration with, any court or other federal, state, local or other governmental authority, self-regulatory organization or other person in connection with the issuance of the Shares pursuant to this Subscription Agreement, other than (i) filings with the SEC, (ii) filings required by applicable state securities laws, (iii) the filings required in accordance with Section 13 of this Subscription Agreement, (iv) those required by The Nasdaq Stock Market LLC (“Nasdaq”), including with respect to obtaining approval of SCS’s shareholders, and (v) the failure of which to obtain would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect.

(g) As of the date hereof, SCS has not received any written communication from a governmental authority that alleges that SCS is not in compliance with or is in default or violation of any applicable law, except where such non-compliance, default or violation would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect.

(h) Assuming the accuracy of the Investor’s representations and warranties set forth in Section 6 of this Subscription Agreement, no registration under the Securities Act of 1933, as amended (the “Securities Act”), is required for the offer and sale of the Shares by SCS to the Investor.

(i) Neither SCS nor any person acting on its behalf has offered or sold the Shares by any form of general solicitation or general advertising in violation of the Securities Act.

(j) The issued and outstanding Class A ordinary shares of SCS are registered pursuant to Section 12(b) of the Exchange Act and are listed for trading on Nasdaq. There is no suit, action, proceeding or investigation pending or, to the knowledge of SCS, threatened against SCS by Nasdaq or the SEC, respectively, to prohibit or terminate the listing of the Shares on Nasdaq or to deregister the Shares under the Exchange Act. SCS has taken no action that is designed to terminate the registration of the Shares under the Exchange Act.

(k) SCS is not under any obligation to pay any broker’s fee or commission in connection with the sale of the Shares other than to the Placement Agents (as defined below).

(l) The Other Subscription Agreements reflect the same Per Share Subscription Price and other terms with respect to the purchase of the Shares that are no more favorable to such subscriber thereunder than the terms of this Subscription Agreement, other than terms particular to the regulatory requirements of such subscriber or its affiliates or related funds. No amendment, waiver or modification to any Other Subscription Agreement has been made that materially benefits such other subscriber thereunder unless the Investor has been offered the same benefits. For the avoidance of doubt, this Section 5(l) shall not apply to any document entered into in connection with the Insider PIPE Investment or the Management PIPE Investment; provided, however, that (i) the Insider PIPE Investment shall be with respect to the same class of ordinary shares being acquired by the Investor hereunder and at the same Per Share Subscription Price and (ii) the Management PIPE Investment shall be with respect to either the same class of ordinary shares being acquired by the Investor hereunder or New Company Common Units (as such term is defined in the Business Combination Agreement) and, at the same Per Share Subscription Price or at $10.00 per New Company Common Unit, as applicable.

(m) Neither SCS nor any of its subsidiaries, affiliates, directors, officers, employees, or, to SCS’s knowledge, (i) the Company nor any of its subsidiaries, affiliates, directors, officers, employees or (ii) SCS’s and the Company’s respective agents or representatives acting on their behalf in connection with this Agreement, is an individual or entity (“Person”) that is, or is owned or controlled by one or more Persons that are: (i) the subject of any sanctions administered or enforced by the United States Government (including the U.S. Department of Treasury’s Office of Foreign Assets Control and the U.S. Department of State), the United Nations Security Council, the European Union, Her Majesty’s Treasury or any other relevant sanctions authority (collectively, “Sanctions”); or (ii) located, organized or resident in a country or territory that is, or whose government is, the subject of comprehensive territorial Sanctions (including, without limitation, Crimea, Cuba, Iran, North Korea, Syria and Venezuela).

6. Investor Representations and Warranties. The Investor represents and warrants to SCS that:

(a) The Investor (i) is a “qualified institutional buyer” (as defined in Rule 144A under the Securities Act) or an “accredited investor” (within the meaning of Rule 501(a) under the Securities Act), in each case, satisfying the applicable requirements set forth on Schedule A hereto, (ii) is acquiring the Shares only for its own account and not for the account of others, or if the Investor is subscribing for the Shares as a fiduciary or agent for one or more investor accounts, the Investor has full investment discretion with respect to each such account, and the full power and authority to make the acknowledgements, representations and agreements herein on behalf of each owner of each such account, and (iii) is not acquiring the Shares with a view to, or for offer or sale in connection with, any distribution thereof in violation of the Securities Act (and shall provide the requested information set forth on Schedule A hereto). The Investor, if such Investor is not a natural person, is not an entity formed for the specific purpose of acquiring the Shares and is an “institutional account” as defined by FINRA Rule 4512(c) of an investment adviser to which the Investor has delegated investment decision making authority. The Investor, or its investment adviser, as applicable, is aware that the sale of the Shares is being made in reliance on a private placement exemption from registration under the Securities Act and is acquiring the Shares for the Investor’s own account or for an account over which it exercises sole discretion for another qualified institutional buyer or accredited investor.

(b) The Investor, or its investment adviser, as applicable, acknowledges and agrees that the Shares are being offered in a transaction not involving any public offering within the meaning of the Securities Act, that the Shares have not been registered under the Securities Act and that SCS is not required to register the Shares except as set forth in Section 8 of this Subscription Agreement. The Investor acknowledges and agrees that the Shares may not be offered, resold, transferred, pledged or otherwise disposed of by the Investor absent an effective registration statement under the Securities Act except (i) to SCS or a subsidiary thereof, (ii) to non-U.S. persons pursuant to offers and sales that occur outside the United States within the meaning of Regulation S under the Securities Act or (iii) pursuant to another applicable exemption from the registration requirements of the Securities Act, and, in each case, in accordance with any applicable securities laws of the states of the United States and other applicable jurisdictions, and that any certificates or book entries representing the Shares shall contain a restrictive legend to such effect (provided that such legend may be subject to removal in accordance with Section 8(d)). The Investor, or its investment adviser, as applicable, acknowledges and agrees that the Shares will be subject to these securities law transfer restrictions and, as a result of these transfer restrictions, the Investor may not be able to readily offer, resell, transfer, pledge or otherwise dispose of the Shares and may be required to bear the financial risk of an investment in the Shares for an indefinite period of time. The Investor, or its investment adviser, as applicable, acknowledges and agrees that the Shares will not immediately be eligible for offer, resale, transfer, pledge or disposition pursuant to Rule 144 promulgated under the Securities Act, and that the provisions of Rule 144(i) will apply to the Shares. The Investor acknowledges and agrees that it has been advised to consult legal, tax and accounting prior to making any offer, resale, transfer, pledge or disposition of any of the Shares.

(c) The Investor acknowledges and agrees that the Investor is purchasing the Shares from SCS, and that SCS, the Company, and/or the Placement Agents and/or their respective affiliates may now or in the future own securities of SCS and may purchase Shares. The Investor further acknowledges that there have been no representations, warranties, covenants and agreements made to the Investor by or on behalf of SCS, the Company, any of their respective affiliates or any control persons, officers, directors, employees, agents or representatives of any of the foregoing or any other person or entity, expressly or by implication, other than those representations, warranties, covenants and agreements of SCS expressly set forth in Section 5 of this Subscription Agreement.

(d) The Investor acknowledges and agrees that the Investor has received or had access to such information as the Investor deems necessary in order to make an investment decision with respect to the Shares, including, with respect to SCS, the Transaction and the business of the Company and its subsidiaries. The Investor acknowledges that Investor has consulted with its own legal, accounting, financial, regulatory, and tax advisors, to the extent deemed appropriate. Without limiting the generality of the foregoing, the Investor acknowledges that it has had the opportunity to review SCS’s filings with the SEC. The Investor acknowledges and agrees that the Investor and the Investor’s professional advisor(s), if any, have had the opportunity to review financial and other information as it deemed necessary to make its decision, and ask such questions, receive such answers and obtain such information as the Investor and such Investor’s professional advisor(s), if any, have deemed necessary to make an investment decision with respect to the Shares.

(e) The Investor acknowledges that certain information provided to the Investor was based on projections, and such projections were prepared based on assumptions and estimates that are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the projections. The Investor acknowledges that such information and projections were prepared without the participation of the Placement Agents and that the Placement Agents, SCS and the Company do not assume responsibility for independent verification of, or the accuracy or completeness of, such information or projections.

(f) The Investor, or its investment adviser, as applicable, became aware of this offering of the Shares solely by means of direct contact between the Investor and SCS, the Company or a representative of SCS or the Company, and the Shares were offered to the Investor solely by direct contact between the Investor and SCS, the Company or a representative of SCS or the Company. The Investor, or its investment adviser, as applicable, did not become aware of this offering of the Shares, nor were the Shares offered to the Investor, by any other means. The Investor acknowledges that the Shares (i) were not offered by any form of general solicitation or general advertising and (ii) are not being offered in a manner involving a public offering under, or in a distribution in violation of, the Securities Act, or any state securities laws. The Investor, or its investment adviser, as applicable, acknowledges that it is not relying upon, and has not relied upon, any statement, representation or warranty made by any person, firm or corporation (including, without limitation, SCS, the Company, the Placement Agents, any of their respective affiliates or any control persons, officers, directors, employees, agents or representatives of any of the foregoing), other than the representations and warranties of SCS contained in Section 5 of this Subscription Agreement, in making its investment or decision to invest in SCS.

(g) The Investor, or its investment adviser, as applicable, acknowledges that it is aware that there are substantial risks incident to the purchase and ownership of the Shares, including those set forth in SCS’s filings with the SEC. The Investor has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of an investment in the Shares, and the Investor has sought such accounting, legal and tax advice as the Investor has considered necessary to make an informed investment decision. The Investor acknowledges that Investor shall be responsible for any of the Investor’s tax liabilities that may arise as a result of the transactions contemplated by this Subscription Agreement, and that neither SCS nor the Company has provided any tax advice or any other representation or guarantee regarding the tax consequences of the transactions contemplated by the Subscription Agreement.

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

(i) In making its decision to purchase the Shares, the Investor has relied solely upon independent investigation made by the Investor and the representations and warranties of SCS in Section 5. Without limiting the generality of the foregoing, the Investor has not relied on any statements or other information provided by or on behalf of the Placement Agents or any of their respective affiliates or any control persons, officers, directors, employees, agents or representatives of any of the foregoing concerning SCS, the Company, the Transaction, the Transaction Agreement, this Subscription Agreement or the transactions contemplated hereby or thereby, the Shares or the offer and sale of the Shares.

(j) The Investor acknowledges and agrees that no federal or state agency has passed upon or endorsed the merits of the offering of the Shares or made any findings or determination as to the fairness of this investment.

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

(l) The execution, delivery and performance by the Investor of this Subscription Agreement are within the powers of the Investor, have been duly authorized and will not constitute or result in a breach or default under or conflict with any order, ruling or regulation of any court or other tribunal or of any governmental commission or agency, or any agreement or other undertaking, to which the Investor is a party or by which the Investor is bound, and will not violate any provisions of the Investor’s organizational documents, including, without limitation, its incorporation or formation papers, bylaws, indenture of trust or partnership or operating agreement, as may be applicable. The signature of the Investor on this Subscription Agreement is genuine, and the signatory has legal competence and capacity to execute the same or the signatory has been duly authorized to execute the same, and, assuming that this Subscription Agreement constitutes the valid and binding agreement of SCS, this Subscription Agreement constitutes a legal, valid and binding obligation of the Investor, enforceable against the Investor in accordance with its terms except as may be limited or otherwise affected by (i) bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium or other laws relating to or affecting the rights of creditors generally, and (ii) principles of equity, whether considered at law or equity.

(m) Neither the Investor nor any of its officers, directors, managers, managing members, general partners, subsidiaries, affiliates, or, to the Investor’s knowledge, the Investor’s agents or representatives acting on their behalf in connection with this Agreement is: (i) a person named on the Specially Designated Nationals and Blocked Persons List, the Foreign Sanctions Evaders List, the Sectoral Sanctions Identification List, or any other similar list of sanctioned persons administered by the U.S. Treasury Department’s Office of Foreign Assets Control, or any similar list of sanctioned persons administered by the European Union, any individual European Union member state or the United Kingdom (collectively, “Sanctions Lists”); (ii) directly or indirectly 50% or more owned or controlled by, or acting on behalf of, one or more persons on a Sanctions List; (iii) organized, incorporated, established, located, resident in, or a citizen, national, or the government, including any political subdivision, agency, or instrumentality thereof, of, Cuba, Iran, North Korea, Syria, Venezuela, the Crimea region of Ukraine, or any other country or territory that is the subject of comprehensive trade restrictions by the United States, the European Union, any individual European Union member state or the United Kingdom; (iv) a Designated National as defined in the Cuban Assets Control Regulations, 31 C.F.R. Part 515; or (v) a non-U.S. shell bank or, to the Investor’s knowledge, providing banking services indirectly to a non-U.S. shell bank (collectively, a “Prohibited Investor”). The Investor represents that if it is a financial institution subject to the Bank Secrecy Act (31 U.S.C. Section 5311 et seq.), as amended by the USA PATRIOT Act of 2001, and its implementing regulations (collectively, the “BSA/PATRIOT Act”), that the Investor maintains policies and procedures reasonably designed to comply with applicable obligations under the BSA/PATRIOT Act. The Investor also represents that it maintains policies and procedures reasonably designed to ensure compliance with sanctions administered by the United States, the European Union, any individual European Union member state or the United Kingdom, to the extent applicable to it. The Investor further represents that the funds held by the Investor and used to purchase the Shares were legally derived and were not obtained, directly or indirectly, from a Prohibited Investor.

(n) If the Investor is or is acting on behalf of (i) an employee benefit plan that is subject to Title I of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), (ii) a plan, an individual retirement account or other arrangement that is subject to Section 4975 of the Internal Revenue Code of 1986, as amended (the “Code”), (iii) an entity whose underlying assets are considered to include “plan assets” of any such plan, account or arrangement described in clauses (i) and (ii) (each, an “ERISA Plan”), or (iv) an employee benefit plan that is a governmental plan (as defined in Section 3(32) of ERISA), a church plan (as defined in Section 3(33) of ERISA), a non-U.S. plan (as described in Section 4(b)(4) of ERISA) or other plan that is not subject to the foregoing clauses (i), (ii) or (iii) but may be subject to provisions under any other federal, state, local, non-U.S. or other laws or regulations that are similar to such provisions of ERISA or the Code (collectively, “Similar Laws,” and together with ERISA Plans, “Plans”), the Investor represents and warrants that (A) neither SCS nor any of its affiliates has provided investment advice or has otherwise acted as the Plan’s fiduciary, with respect to its decision to acquire and hold the Shares, and none of the parties to the Transaction is or shall at any time be the Plan’s fiduciary with respect to any decision in connection with the Investor’s investment in the Shares; and (B) its purchase of the Shares will not result in a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code, or any applicable Similar Law.

(o) No disclosure or offering document has been prepared by Citigroup Global Markets Inc., Morgan Stanley & Co. LLC, Jefferies LLC, Evercore Group LLC, and UBS Securities LLC (collectively, the “Placement Agents”) or any of their respective affiliates in connection with the offer and sale of the Shares.

(p) None of the Placement Agents, nor any of their respective affiliates, nor any control persons, officers, directors, employees, agents or representatives of any of the foregoing has made any independent investigation with respect to SCS, the Company or its subsidiaries or any of their respective businesses, or the Shares or the accuracy, completeness or adequacy of any information supplied to the Investor by SCS.

(q) The Investor agrees that the Placement Agents shall not be liable to the Investor (including in contract, tort, under federal or state securities laws or otherwise) for any action heretofore or hereafter taken or omitted to be taken in connection with the purchase of the Shares. On behalf of the Investor and its affiliates, the Investor releases the Placement Agents in respect of any losses, claims, damages, obligations, penalties, judgments, awards, liabilities, costs, expenses or disbursements related to the purchase of the Shares. This undertaking is given freely and after obtaining independent legal advice.

(r) In connection with the issue and purchase of the Shares, none of the Placement Agents, nor any of their respective affiliates, has acted as the Investor’s financial advisor or fiduciary.

(s) The Investor is aware that Citigroup Global Markets Inc. is acting as one of SCS’s placement agents and is also acting as financial advisor to the Company in connection with the business combination of SCS and the Company.

(t) When required to deliver payment to SCS pursuant to Section 2 above, the Investor will have sufficient funds to pay the Subscription Amount and consummate the purchase and sale of the Shares pursuant to this Subscription Agreement.

(u) Notwithstanding anything to the contrary set forth herein, the Investor acknowledges and agrees that, subsequent to the date of this Subscription Agreement and prior to the Closing, SCS may enter into one or more additional subscription agreements (the “Additional Subscription Agreements”) with other investors with terms and conditions that are not more advantageous to the investor thereunder than the terms and conditions set forth in this Subscription Agreement (other than terms particular to the regulatory requirements of such other investor or its affiliates or related funds that are mutual funds or that have been offered to Investor), and entry into such subscription agreements may increase the aggregate amount of Shares being subscribed for in the private placement contemplated by this Subscription Agreement. For the avoidance of doubt, such additional subscription agreements shall reflect not less than the same Per Share Subscription Price and shall, once executed, constitute Other Subscription Agreements for purposes of this Agreement, mutatis mutandis.

7. No Hedging. The Investor hereby agrees that neither he, she or it, his, her or its controlled affiliates, nor any person or entity acting on his, her or its or his, her or its controlled affiliates’ behalf or pursuant to any understanding with him, her or it, shall execute any short sales (as such term is defined in Regulation SHO under the Exchange Act, 17 CFR 242.200) or engage in other hedging transactions of any kind with respect to the Shares during the period from the date of this Subscription Agreement through the Closing (or such earlier termination of this Subscription Agreement). Nothing in this Section 6 shall prohibit any other investment portfolios of Investor that have no knowledge of this Subscription Agreement or of the Investor’s participation in this Transaction and have not been informed by the Investor of the Transaction (including Investor’s affiliates) from entering into any short sales or engaging in other hedging transactions and, if the Investor is a multi-managed investment vehicle, whereby separate portfolio managers manage separate portions of the Investor’s assets, and the portfolio managers have no knowledge of the investment decisions made by the portfolio managers managing other portions of the Investor’s assets, then, in each case, this Section 7 shall only apply with respect to the portion of the assets managed by the portfolio manager that made the investment decision to purchase the Shares to be issued pursuant to this Subscription Agreement.

8. Registration Rights.

(a) SCS agrees that, within thirty (30) calendar days following the Closing Date (such deadline, the “Filing Deadline”), SCS will submit to or file with the SEC (at its sole cost and expense) a registration statement for a shelf registration on Form S-1 or Form S-3 (if SCS is then eligible to use a Form S-3 shelf registration) (the “Registration Statement”), in each case, covering the resale of the Shares acquired by the Investor pursuant to this Subscription Agreement (such Shares and, unless issued in a transaction registered under the Securities Act, any other equity security issued or issuable with respect to such Shares by way of stock split, dividend, distribution, recapitalization, merger, exchange, replacement or similar event, the “Registrable Shares”) and SCS shall use its commercially reasonable efforts to have the Registration Statement declared effective as soon as practicable after the filing thereof, but no later than the earlier of (i) the ninetieth (90^th) calendar day following the filing date thereof if the SEC notifies SCS (orally or in writing, whichever is earlier) that it will “review” the Registration Statement and (ii) the fifth (5^th) business day after the date SCS 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 (such earlier date, the “Effectiveness Deadline”); provided, however, that SCS’s obligations to include the Registrable Shares in the Registration Statement are contingent upon the Investor furnishing in writing to SCS such information regarding the Investor or its permitted assigns, the securities of SCS held by the Investor and the intended method of disposition of the Registrable Shares (which shall be limited to non-underwritten public offerings) as shall be reasonably requested by SCS to effect the registration of the Registrable Shares, and the Investor shall execute such documents in connection with such registration as SCS may reasonably request that are customary of a selling stockholder in similar situations, including providing that SCS shall be entitled to postpone and suspend the effectiveness or use of the Registration Statement, if applicable, during any customary blackout or similar period or as permitted hereunder; provided that the Investor shall not in connection with the foregoing be required to execute any lock-up or similar agreement or otherwise be subject to any contractual restriction on the ability to transfer the Registrable Shares. For as long as the Investor holds Shares, SCS will use commercially reasonable efforts to file all reports for so long as the condition in Rule 144(c)(1) (or Rule 144(i)(2), if applicable) is required to be satisfied, and provide all customary and reasonable cooperation, necessary to enable the undersigned to resell the Shares pursuant to Rule 144 of the Securities Act (in each case, when Rule 144 of the Securities Act becomes available to the Investor). Any failure by SCS to file the Registration Statement by the Filing Deadline or to have the Registration Statement declared effective by the Effectiveness Deadline shall not otherwise relieve SCS of its obligations to file the Registration Statement or to have the Registration Statement declared effective as set forth above in this Section 8.

(b) At its expense SCS shall:

(i) except for such times as SCS is permitted hereunder to suspend the use of the prospectus forming part of a Registration Statement, use its commercially reasonable efforts to keep such registration, and any qualification, exemption or compliance under state securities laws which SCS determines to obtain, continuously effective with respect to the Investor, and to keep the applicable Registration Statement or any subsequent shelf registration statement free of any material misstatements or omissions, until the earlier of the following: (A) the Investor ceases to hold any Registrable Shares, (B) the date all Registrable Shares held by the Investor may be sold without restriction under Rule 144, including, without limitation, any volume and manner of sale restrictions which may be applicable to affiliates under Rule 144 and without the requirement for SCS to be in compliance with the current public information required under Rule 144(c)(1) (or Rule 144(i)(2), if applicable), and (C) two (2) years from the date of effectiveness of the Registration Statement. The period of time during which SCS is required hereunder to keep a Registration Statement effective is referred to herein as the “Registration Period”;

(ii) during the Registration Period, advise the Investor, as expeditiously as possible:

(1) when a Registration Statement or any amendment thereto has been filed with the SEC;

(2) after it shall receive notice or obtain knowledge thereof, of the issuance by the SEC of any stop order suspending or other matter causing the suspension of the effectiveness of any Registration Statement or the initiation of any proceedings for such purpose;

(3) of the receipt by SCS of any notification with respect to the suspension of the qualification of the Registrable Shares included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and

(4) subject to the provisions in this Subscription Agreement, of the occurrence of any event that requires the making of any changes in any Registration Statement or prospectus so that, as of such date, the statements therein are not misleading and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in the light of the circumstances under which they were made) not misleading. Notwithstanding anything to the contrary set forth herein, SCS shall not, when so advising the Investor of such events, provide the Investor with any material, nonpublic information regarding SCS other than to the extent that providing notice to the Investor of the occurrence of the events listed in (1) through (4) above constitutes material, nonpublic information regarding SCS;

(iii) during the Registration Period, use its commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of any Registration Statement as soon as reasonably practicable;

(iv) during the Registration Period, upon the occurrence of any event contemplated in Section 8(b)(ii)(4) above, except for such times as SCS is permitted hereunder to suspend, and has suspended, the use of a prospectus forming part of a Registration Statement, use its commercially reasonable efforts to, as soon as reasonably practicable, prepare a post-effective amendment to such Registration Statement or a supplement to the related prospectus, or file any other required document so that, as thereafter delivered to purchasers of the Registrable Shares included therein, such prospectus will not include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(v) during the Registration Period, use its commercially reasonable efforts to cause all Registrable Shares to be listed on the national securities exchange on which the Class A ordinary shares issued by SCS have been listed;

(vi) during the Registration Period, use its commercially reasonable efforts to allow the Investor to review disclosure regarding the Investor in the Registration Statement; and

(vii) during the Registration Period, otherwise, in good faith, cooperate reasonably with, and take such customary actions as may reasonably be requested by the Investor, consistent with the terms of this Subscription Agreement, in connection with the registration of the Registrable Shares.

(c) Notwithstanding anything to the contrary in this Subscription Agreement, SCS shall be entitled to delay the filing or effectiveness of, or suspend the use of, the Registration Statement if (i) it determines that in order for the Registration Statement not to contain a material misstatement or omission, (A) an amendment thereto would be needed to include information that would at that time not otherwise be required in a current, quarterly or annual report under the Exchange Act, or (B) the negotiation or consummation of a transaction by SCS or its subsidiaries is pending or an event has occurred, which negotiation, consummation or event SCS’s board of directors reasonably believes would require additional disclosure by SCS in the Registration Statement of material information that SCS has a bona fide business purpose for keeping confidential and the non-disclosure of which in the Registration Statement would be expected, in the reasonable determination of SCS’s board of directors to cause the Registration Statement to fail to comply with applicable disclosure requirements, or (ii) in the good faith judgment of SCS’s board of directors, such filing or effectiveness or use of such Registration Statement would be seriously detrimental to SCS and SCS’s board of directors concludes as a result that it is essential to defer such filing (each such circumstance, a “Suspension Event”); provided, however, that SCS may not delay or suspend the Registration Statement on more than two occasions or for more than forty-five (45) consecutive calendar days, or more than sixty (60) total calendar days, in each case during any twelve (12) month period. Upon receipt of any written notice from SCS of the happening of any Suspension Event during the period that the Registration Statement is effective or if as a result of a Suspension Event the Registration Statement or related prospectus contains any untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein (in light of the circumstances under which they were made, in the case of the prospectus) not misleading, the Investor agrees that (i) it will immediately discontinue offers and sales of the Registrable Shares under the Registration Statement (excluding, for the avoidance of doubt, sales conducted pursuant to Rule 144) until the Investor receives copies of a supplemental or amended prospectus (which SCS agrees to promptly prepare) that corrects the misstatement(s) or omission(s) referred to above and receives notice that any post-effective amendment has become effective or unless otherwise notified by SCS that it may resume such offers and sales, and (ii) it will maintain the confidentiality of any information included in such written notice delivered by SCS unless otherwise required by law or subpoena. If so directed by SCS, the Investor will deliver to SCS or, in the Investor’s sole discretion destroy, all copies of the prospectus covering the Registrable Shares in the Investor’s possession; provided, however, that this obligation to deliver or destroy all copies of the prospectus covering the Registrable Shares shall not apply (A) to the extent the Investor is required to retain a copy of such prospectus (1) in order to comply with applicable legal, regulatory, self-regulatory or professional requirements or (2) in accordance with a bona fide pre-existing document retention policy or (B) to copies stored electronically on archival servers as a result of automatic data back-up.

(d) If the Shares acquired hereunder are either eligible to be sold (i) pursuant to an effective Registration Statement or (ii) without restriction under, and without SCS being in compliance with the current public information requirements of, Rule 144 under the Securities Act, then at the Investor’s request, SCS shall use its commercially reasonable efforts to cause its transfer agent to remove any restrictive legends related to the book entry account holding such Shares and make a new, unlegended entry for such book entry Shares without restrictive legends within two (2) trading days of any such request therefor from the Investor, provided that SCS and its transfer agent have timely received from the Investor customary representations and other documentation reasonably requested by SCS and its transfer agent in connection therewith. Subject to receipt from the Investor by SCS and its transfer agent of customary representations and other documentation reasonably requested by SCS and its transfer agent in connection therewith, including, if required by SCS’s transfer agent, an opinion of SCS’s counsel, in a form reasonably acceptable to its transfer agent, to the effect that the removal of such restrictive legends in such circumstances may be effected under the Securities Act, the Investor may request that SCS remove any legend from the book entry position evidencing its Shares following the earliest of such time as such Shares (i) are covered by and may be sold or transferred pursuant to an effective registration statement, (ii) have been or are about to be sold pursuant to Rule 144, or (iii) are eligible for resale under Rule 144(b)(1) or any successor provision without the requirement for SCS to be in compliance with the current public information requirement under Rule 144 and without volume or manner-of-sale restrictions applicable to the sale or transfer of such Shares. If restrictive legends are no longer required for such Shares pursuant to the foregoing, SCS shall, in accordance with the provisions of this Section 8(d) and within two (2) trading days of any request therefor from the Investor accompanied by such customary and reasonably acceptable representations and other documentation referred to above establishing that restrictive legends are no longer required, use its commercially reasonable efforts to deliver to its transfer agent irrevocable instructions and, upon the transfer agent’s request, a legal opinion of SCS’s counsel, that the transfer agent shall make a new, unlegended entry for such book entry Shares. SCS shall be responsible for the fees of its transfer agent and its legal counsel associated with such removal of legends.

(e) Indemnification.

(i) SCS agrees to indemnify, to the extent permitted by law, the Investor (to the extent a seller under the Registration Statement), its directors and officers and each person who controls the Investor (within the meaning of the Securities Act), to the extent permitted by law, against all losses, claims, damages, liabilities and reasonable and documented out-of-pocket expenses (including reasonable and documented attorneys’ fees of one law firm (and one firm of local counsel)) caused by any untrue or alleged untrue statement of material fact contained in any Registration Statement, prospectus included in any Registration Statement (“Prospectus”) or preliminary Prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of a Prospectus, in the light of the circumstances under which they were made) not misleading, except insofar as the same are caused by or contained in any information or affidavit so furnished in writing to SCS by or on behalf of the Investor expressly for use therein.

(ii) In connection with any Registration Statement in which the Investor is participating, the Investor shall furnish (or cause to be furnished) to SCS in writing such information and affidavits as SCS reasonably requests for use in connection with any such Registration Statement or Prospectus and, to the extent permitted by law, shall indemnify SCS, its directors and officers and each person or entity who controls SCS (within the meaning of the Securities Act) against any losses, claims, damages, liabilities and expenses (including, without limitation, reasonable and documented outside attorneys’ fees) resulting from any untrue or alleged untrue statement of material fact contained or incorporated by reference in any Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of a Prospectus, in the light of the circumstances under which they were made) not misleading, but only to the extent that such untrue statement or omission is contained (or not contained in, in the case of an omission) in any information or affidavit so furnished in writing by on behalf of the Investor expressly for use therein; provided, however, that the liability of the Investor shall be several and not joint with any other investor and shall be in proportion to and limited to the net proceeds received by the Investor from the sale of Registrable Shares giving rise to such indemnification obligation.

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

(iv) The indemnification provided for under this Subscription Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling person or entity of such indemnified party and shall survive the transfer of securities purchased pursuant to this Subscription Agreement.

(v) If the indemnification provided under this Section 8(e) from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and expenses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations; provided, however, that the liability of the Investor shall be limited to the net proceeds received by the Investor from the sale of Registrable Shares giving rise to such indemnification obligation. The relative fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by (or not made by, in the case of an omission), or relates to information supplied by (or not supplied by, in the case of an omission), such indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action. The amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include, subject to the limitations set forth in Sections 8(e)(i), (ii) and (iii) above, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this Section 8(e)(v) from any person or entity who was not guilty of such fraudulent misrepresentation.

9. Termination. This Subscription Agreement shall terminate and be void and of no further force and effect, and all rights and obligations of the parties hereunder shall terminate without any further liability on the part of any party in respect thereof, upon the earliest to occur of (a) such date and time as the Transaction Agreement is terminated in accordance with its terms, (b) upon the mutual written agreement of each of the parties hereto to terminate this Subscription Agreement, (c) if the conditions to Closing set forth in Section 3 of this Subscription Agreement are not satisfied at the Closing and, as a result thereof, the transactions contemplated by this Subscription Agreement will not be or are not consummated at the Closing and (d) September 18, 2022; provided that nothing herein will relieve any party from liability for any willful breach hereof prior to the time of termination, and each party will be entitled to any remedies at law or in equity to recover losses, liabilities or damages arising from any such willful breach. SCS shall notify the Investor of the termination of the Transaction Agreement promptly after the termination thereof. Upon the termination of this Subscription Agreement in accordance with this Section 9, any monies paid by the Investor to SCS to purchase Shares hereunder shall be promptly (and in any event within one (1) business day after such termination) returned to the Investor.

10. Trust Account Waiver. The Investor acknowledges that SCS is a blank check company with the powers and privileges to effect a merger, asset acquisition, reorganization or similar business combination involving SCS and one or more businesses or assets. The Investor further acknowledges that, as described in SCS’s prospectus relating to its initial public offering dated June 29, 2021 (the “IPO Prospectus”) available at www.sec.gov, substantially all of SCS’s assets consist of the cash proceeds of SCS’s initial public offering and private placement of its securities, and substantially all of those proceeds have been deposited in a trust account (the “Trust Account”) for the benefit of SCS, its public shareholders and the underwriter of SCS’s initial public offering. Except with respect to interest earned on the funds held in the Trust Account that may be released to SCS to pay its tax obligations, if any, the cash in the Trust Account may be disbursed only for the purposes set forth in the IPO Prospectus. For and in consideration of SCS entering into this Subscription Agreement, the receipt and sufficiency of which are hereby acknowledged, the Investor hereby irrevocably waives any and all right, title and interest, or any claim of any kind it has or may have in the future, in or to any monies held in the Trust Account, and agrees not to seek recourse against the Trust Account as a result of, or arising out of, this Subscription Agreement; provided that nothing in this Section 10 shall be deemed to limit the Investor’s right, title, interest or claim to the Trust Account by virtue of the Investor’s record or beneficial ownership of Class A ordinary shares of SCS acquired by any means other than pursuant to this Subscription Agreement.

11. Miscellaneous.

(a) Neither this Subscription Agreement nor any rights that may accrue to the Investor hereunder (other than the Shares acquired hereunder, if any) may be transferred or assigned, other than an assignment to any fund or account managed by the same investment manager as the Investor or an affiliate thereof, subject to, if such transfer or assignment is prior to the Closing, such transferee or assignee, as applicable, executing a joinder to this Subscription Agreement or a separate subscription agreement in substantially the same form as this Subscription Agreement, including with respect to the Subscription Amount and other terms and conditions; provided that, in the case of any such transfer or assignment, the initial party to this Subscription Agreement shall remain bound by its obligations under this Subscription Agreement in the event that the transferee or assignee, as applicable, does not comply with its obligations to consummate the purchase of Shares contemplated hereby. Neither this Subscription Agreement nor any rights that may accrue to SCS hereunder or any of SCS’s obligations may be transferred or assigned other than pursuant to the Transaction.

(b) SCS may request from the Investor such additional information as SCS may deem necessary to evaluate the eligibility of the Investor to acquire the Shares and in connection with the inclusion of the Shares in the Registration Statement, and the Investor shall provide such information as may reasonably be requested, to the extent readily available and to the extent consistent with its internal policies and procedures; provided that SCS agrees to keep any such information provided by the Investor confidential, except as required by laws, rules or regulations, at the request of the staff of the SEC or another regulatory agency or by the regulations of the Nasdaq. The Investor acknowledges that SCS may file a copy of the form of this Subscription Agreement with the SEC as an exhibit to or within a current or periodic report or a registration statement of SCS.

(c) The Investor acknowledges that SCS and the Placement Agents (as third party beneficiaries with the right to enforce Section 4, Section 5, Section 6, Section 11, and Section 12 hereof on their own behalf and not, for the avoidance of doubt, on behalf of SCS) will rely on the acknowledgments, understandings, agreements, representations and warranties of the Investor contained in this Subscription Agreement. Prior to the Closing, the Investor agrees to promptly notify SCS and the Placement Agents if any of the acknowledgments, understandings, agreements, representations and warranties of the Investor set forth herein are no longer accurate.

(d) SCS, the Company, the Placement Agents and the Investor are each entitled to rely upon this Subscription Agreement and each is irrevocably authorized to produce this Subscription Agreement or a copy hereof to any interested party in any administrative or legal proceeding or official inquiry with respect to the matters covered hereby.

(e) All of the representations and warranties contained in this Subscription Agreement shall survive the Closing. All of the covenants and agreements made by each party hereto in this Subscription Agreement shall survive the Closing until the applicable statute of limitations or in accordance with their respective terms, if a shorter period.

(f) This Subscription Agreement may not be modified, waived or terminated (other than pursuant to the terms of Section 9 above) except by an instrument in writing, signed by each of the parties hereto and, to the extent required by the Transaction Agreement, the Company. No failure or delay of either party in exercising any right or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such right or power, or any course of conduct, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the parties and third party beneficiaries hereunder are cumulative and are not exclusive of any rights or remedies that they would otherwise have hereunder.

(g) This Subscription Agreement (including the schedule hereto) constitutes the entire agreement, and supersedes all other prior agreements, understandings, representations and warranties, both written and oral, among the parties, with respect to the subject matter hereof. Except as set forth in Section 8(e), Section 11(c) with respect to the persons referenced therein, this Subscription Agreement shall not confer any rights or remedies upon any person other than the parties hereto, and their respective successor and assigns.

(h) Except as otherwise provided herein, this Subscription Agreement shall be binding upon, and inure to the benefit of the parties hereto and their heirs, executors, administrators, successors, legal representatives and permitted assigns, and the agreements, representations, warranties, covenants and acknowledgments contained herein shall be deemed to be made by, and be binding upon, such heirs, executors, administrators, successors, legal representatives and permitted assigns.

(i) If any provision of this Subscription Agreement shall be adjudicated by a court of competent jurisdiction to be invalid, illegal or unenforceable, the validity, legality or enforceability of the remaining provisions of this Subscription Agreement shall not in any way be affected or impaired thereby and shall continue in full force and effect.

(j) Without limiting any remedies of a party hereunder for a breach of this Subscription Agreement by the other party, each party shall pay its own costs and expenses incurred in connection with the negotiation and execution of this Subscription Agreement and consummation of the transactions contemplated hereby, whether or not such transactions are consummated.

(k) This Subscription Agreement may be executed in one or more counterparts (including by electronic mail or in .pdf) and by different parties in separate counterparts, with the same effect as if all parties hereto had signed the same document. All counterparts so executed and delivered shall be construed together and shall constitute one and the same agreement.

(l) The parties hereto acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Subscription Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Subscription Agreement and to specific enforcement of this Subscription Agreement, in addition to any other remedy to which any party is entitled at law, in equity, in contract, in tort or otherwise. In the event that any claim, action, suit or proceeding shall be brought in equity to enforce the provisions of this Subscription Agreement, no party hereto shall allege, and each party hereto hereby waives the defense, that there is an adequate remedy at law, and each party hereto agrees to waive any requirement for the securing or posting of any bond in connection therewith.

(m) Any claim, action, suit or proceeding based upon, arising out of or related to this Subscription Agreement or the transactions contemplated hereby must be brought in the Court of Chancery of the State of Delaware (or, only to the extent such court does not have subject matter jurisdiction, the Superior Court of the State of Delaware or, if it has or can acquire jurisdiction, in the United States District Court for the District of Delaware), and each of the parties hereto irrevocably and unconditionally (i) consents and submits to the exclusive jurisdiction of each such court in any such claim, action, suit or proceeding, (ii) waives any objection it may now or hereafter have to personal jurisdiction, venue or to convenience of forum, (iii) agrees that all claims in respect of such action, suit or proceeding shall be heard and determined only in any such court and (iv) agrees not to bring any claim, action, suit or proceeding arising out of or relating to this Subscription Agreement or the transactions contemplated hereby in any other court. Nothing herein contained shall be deemed to affect the right of any party to serve process in any manner permitted by law or to commence legal proceedings or otherwise proceed against any other party in any other jurisdiction to enforce judgments obtained in any claim, action, suit or proceeding brought in accordance with this Section 11(m), provided that service of process with respect to any such claim, action, suit or proceeding may also be made upon any party hereto by mailing a copy thereof by registered or certified mail, postage prepaid, to such party at its address as provided in Section 14.

(n) This Subscription Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, without regard to the principles of conflicts of laws that would otherwise require the application of the law of any other State.

(o) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS SUBSCRIPTION AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS SUBSCRIPTION AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS SUBSCRIPTION AGREEMENT. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (I) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER; (II) SUCH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THE FOREGOING WAIVER; (III) SUCH PARTY MAKES THE FOREGOING WAIVER VOLUNTARILY; AND (IV) SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS SUBSCRIPTION AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVER AND CERTIFICATIONS IN THIS SECTION 11(o).

12. Non-Reliance and Exculpation. The Investor acknowledges that it is not relying upon, and has not relied upon, any statement, representation or warranty made by any person, firm or corporation (including, without limitation, the Placement Agents, any of their respective affiliates or any control persons, officers, directors, employees, partners, agents or representatives of any of the foregoing), other than the statements, representations and warranties of SCS expressly contained in Section 5 of this Subscription Agreement, in making its investment or decision to invest in SCS. The Investor acknowledges and agrees that, to the maximum extent permitted by law, none of (i) any other investor pursuant to this Subscription Agreement or any Other Subscription Agreement (including any such investor’s respective affiliates or any control persons, officers, directors, employees, partners, agents or representatives of any of the foregoing), (ii) the Placement Agents, their respective affiliates or any control persons, officers, directors, employees, partners, agents or representatives of any of the foregoing, (iii) any party to the Transaction Agreement (other than SCS) or (iv) any affiliates, or any control persons, officers, directors, employees, partners, agents or representatives of any of SCS, the Company or any other party to the Transaction Agreement shall be liable to the Investor pursuant to this Subscription Agreement, the negotiation hereof or the subject matter hereof, or the transactions contemplated hereby, for any action heretofore or hereafter taken or omitted to be taken by any of them in connection with the purchase of the Shares.

13. Press Releases. SCS shall, by 9:00 a.m., New York City time, on the first business day immediately following the date of this Subscription Agreement, issue one or more press releases or furnish or file with the SEC a Current Report on Form 8-K, registration statement or proxy statement for the Transaction (collectively, the “Disclosure Document”) disclosing, to the extent not previously publicly disclosed, the PIPE Investment, all material terms of the Transaction and any other material, non-public information about SCS or the Transaction that SCS has provided to the Investor at any time prior to the filing of the Disclosure Document. From and after the disclosure of the Disclosure Document, to the knowledge of SCS, the Investor shall not be in possession of any material, non-public information about SCS or the Transaction received from SCS, unless otherwise agreed in writing by such Investor. All press releases or other public communications or marketing materials relating to the transactions contemplated hereby between SCS and the Investor, and the method of the release for publication thereof, shall be subject to the prior approval of (i) SCS and (ii) to the extent such press release or public communication references the Investor or its affiliates or investment advisers by name, the Investor in writing. The restriction in this Section 13 shall not apply to the extent the public announcement is required by applicable securities law, any governmental authority or stock exchange rule; provided that in such an event, the applicable party shall use its commercially reasonable efforts to consult with the other party in advance as to its form, content and timing.

14. Notices. All notices and other communications among the parties shall be in writing and shall be deemed to have been duly given (i) when delivered in person, (ii) when delivered after posting in the United States mail having been sent registered or certified mail return receipt requested, postage prepaid, (iii) when delivered by FedEx or other nationally recognized overnight delivery service, or (iv) when delivered by email (in each case in this clause (iv), solely if receipt is confirmed, but excluding any automated reply, such as an out-of-office notification), addressed as follows:

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 Commission such amendments, including post-effective amendments, and supplements as may be necessary to keep a Shelf continuously effective, available for use to permit the Holders named therein to sell their Registrable Securities included therein and in compliance with the provisions of the Securities Act until such time as there are no longer any Registrable Securities. In the event the Company files a Form S-1 Shelf, the Company shall use its commercially reasonable efforts to convert the Form S-1 Shelf (and any Subsequent Shelf Registration Statement) to a Form S-3 Shelf as soon as practicable after the Company is eligible to use Form S-3. The Company’s obligation under this Section 2.1.1, shall, for the avoidance of doubt, be subject to Section 3.4.

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

2.1.3 Additional Registrable Securities. Subject to Section 3.4, in the event that any Holder holds Registrable Securities that are not registered for resale on a delayed or continuous basis, the Company, upon written request of the Sponsor, a ProKidney Holder, an Investor Stockholder, a Director Holder or an Advisor Holder, shall use commercially reasonable efforts to cause the resale of such Registrable Securities to be covered by either, at the Company’s option, any then available Shelf (including by means of a post-effective amendment) or by filing a Subsequent Shelf Registration Statement and cause the same to become effective as soon as practicable after such filing and such Shelf or Subsequent Shelf Registration Statement shall be subject to the terms hereof; provided, however, that the Company shall only be required to cause such Registrable Securities to be so covered twice per calendar year for each of the Sponsor, each ProKidney Holder, each Investor Stockholder, each Director Holder and each Advisor Holder; provided, further, that prior to making such filing with respect to any written request by a Holder, the Company shall notify the other Holders and provide such other Holders a reasonable opportunity to include additional Registrable Securities held by such other Holders in such filing.

2.1.4 Requests for Underwritten Shelf Takedowns. Subject to Section 3.4, at any time and from time to time when an effective Shelf is on file with the Commission, the Sponsor, an Investor Stockholder or a ProKidney Holder (any of the Sponsor, an Investor Stockholder or a ProKidney Holder being, in such case, a “Demanding Holder”) may request to sell all or any portion of its Registrable Securities in an Underwritten Offering that is registered pursuant to the Shelf (each, an “Underwritten Shelf Takedown”); provided that the Company shall only be obligated to effect an Underwritten Shelf Takedown if such offering shall include Registrable Securities proposed to be sold by the Demanding Holder, either individually or together with other Demanding Holders, with a total offering price reasonably expected to exceed, in the aggregate, $50.0 million (the “Minimum Takedown Threshold”). All requests for Underwritten Shelf Takedowns shall be made by giving written notice to the Company, which shall specify the approximate number of Registrable Securities proposed to be sold in the Underwritten Shelf Takedown. Subject to Section 2.4.4, the Underwriters for such offering (which shall consist of one or more reputable nationally recognized investment banks) shall be selected by the majority-in-interest of the Demanding Holders, subject to the Company’s prior approval (which shall not be unreasonably withheld, conditioned or delayed). The Sponsor, an Investor Stockholder and a ProKidney Holder may each demand not more than (i) one (1) Underwritten Shelf Takedown pursuant to this Section 2.1.4 within any six (6) month period or (ii) two (2) Underwritten Shelf Takedowns pursuant to this Section 2.1.4 in any twelve (12) month period. Notwithstanding anything to the contrary in this Agreement, the Company may effect any Underwritten Offering pursuant to any then effective Registration Statement, including a Form S-3, that is then available for such offering.

2.1.5 Reduction of Underwritten Offering. If the managing Underwriter or Underwriters in an Underwritten Shelf Takedown, in good faith, advises the Company, the Demanding Holders and the Holders requesting piggy back rights pursuant to this Agreement with respect to such Underwritten Shelf Takedown (the “Requesting Holders”) (if any) in writing that the dollar amount or number of Registrable Securities that the Demanding Holders and the Requesting Holders (if any) desire to sell, taken together with all other shares of Class A Common Stock or other equity securities that the Company desires to sell and the shares of Class A Common Stock or other equity securities, if any, as to which a Registration has been requested pursuant to separate written contractual piggy-back registration rights held by any other stockholders who desire to sell, exceeds the maximum dollar amount or maximum number of equity securities that can be sold in the Underwritten Offering without adversely affecting the proposed offering price, the timing, the distribution method, or the probability of success of such offering (such maximum dollar amount or maximum number of such securities, as applicable, the “Maximum Number of Securities”), then the Company shall include in such Underwritten Offering, before including any shares of Class A Common Stock or other equity securities proposed to be sold by Company or by other holders of Class A Common Stock or other equity securities, the Registrable Securities of the Demanding Holders and the Requesting Holders (if any) (pro rata based on the respective number of Registrable Securities that each Demanding Holder and Requesting Holder (if any) has requested be included in such Underwritten Shelf Takedown and the aggregate number of Registrable Securities that the Demanding Holders and Requesting Holders have requested be included in such Underwritten Shelf takedown) that can be sold without exceeding the Maximum Number of Securities.

2.1.6 Withdrawal. Prior to the filing of the applicable “red herring” prospectus or prospectus supplement used for marketing such Underwritten Shelf Takedown, any Demanding Holder initiating an Underwritten Shelf Takedown shall have the right to withdraw from such Underwritten Shelf Takedown for any or no reason whatsoever upon written notification (a “Withdrawal Notice”) to the Company and the Underwriter or Underwriters (if any) of their intention to withdraw from such Underwritten Shelf Takedown; provided that the Sponsor, an Investor Stockholder or a ProKidney Holder may elect to have the Company continue an Underwritten Shelf Takedown if the Minimum Takedown Threshold would still be satisfied by the Registrable Securities proposed to be sold in the Underwritten Shelf Takedown by the Sponsor, the Investor Stockholders, the ProKidney Holders or any of their respective Permitted Transferees, as applicable. If withdrawn by a Demanding Holder, the Sponsor, an Investor Stockholder or a ProKidney Holder may elect to continue an Underwritten Shelf Takedown pursuant to the proviso in the immediately preceding sentence and such Underwritten Shelf Takedown shall instead count as an Underwritten Shelf Takedown demanded by the Sponsor, such Investor Stockholder or such ProKidney Holder, as applicable, for purposes of Section 2.1.4. Following the receipt of any Withdrawal Notice, the Company shall promptly forward such Withdrawal Notice to any other Holders that had elected to participate in such Shelf Takedown and shall not include the Registrable Securities of such withdrawing Demanding Holder in the applicable registration and such Registrable Securities shall continue to be Registrable Securities for all purposes of this Agreement (subject to the other terms and conditions of this Agreement). Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with a Shelf Takedown prior to its withdrawal under this Section 2.1.6.

2.2 Piggyback Registration.

2.2.1 Piggyback Rights. Subject to Section 2.4.3, if the Company or any Holder proposes to conduct a registered offering of, or if the Company proposes to file a Registration Statement under the Securities Act with respect to the Registration of, equity securities, or securities or other obligations exercisable or exchangeable for, or convertible, into equity securities, for its own account or for the account of stockholders of the Company (or by the Company and by the stockholders of the Company including, without limitation, an Underwritten Shelf Takedown pursuant to Section 2.1), other than a Registration Statement (or any registered offering with respect thereto) (i) filed in connection with any employee stock option or other benefit plan, (ii) pursuant to a Registration Statement on Form S-4 (or similar form that relates to a transaction subject to Rule 145 under the Securities Act or any successor rule thereto), (iii) for an offering of debt that is convertible into equity securities of the Company, (iv) for a dividend reinvestment plan or (v) a Block Trade, then the Company shall give written notice of such proposed offering to all of the Holders of Registrable Securities as soon as practicable but not less than ten (10) days before the anticipated filing date of such Registration Statement or, in the case of an Underwritten Offering pursuant to a Shelf Registration, the applicable “red herring” prospectus or prospectus supplement used for marketing such offering (or such shorter period of days (but not less than two (2) days) as may be agreed by holders of at least 25% of the outstanding Registrable Securities), which notice shall (A) describe the amount and type of securities to be included in such offering, the proposed filing date, the intended method(s) of distribution, the name of the proposed managing Underwriter or Underwriters, if any, in such offering and to the extent then known a good faith estimate of the proposed minimum offering price, and (B) offer to all of the Holders of Registrable Securities the opportunity to include in such registered offering such number of Registrable Securities as such Holders may request in writing within five (5) days (or such shorter period of days (but not less than one (1) day) as may be agreed by holders of at least 25% of the outstanding Registrable Securities) after receipt of such written notice (such registered offering, a “Piggyback Registration”).

3.1.14 in the event of any Underwritten Offering or sale by a broker, placement agent or sales agent pursuant to such Registration, enter into and perform its obligations under an underwriting or other purchase or sales agreement, in usual and customary form, with the managing Underwriter or the broker, placement agent or sales agent of such offering or sale;

3.1.15 make available to its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least twelve (12) months beginning with the first day of the Company’s first full calendar quarter after the effective date of the Registration Statement which satisfies the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder (or any successor rule then in effect);

3.1.16 with respect to an Underwritten Offering pursuant to Section 2.1.4, make available senior executives of the Company to participate in meetings with analysts or customary “road show” presentations that may be reasonably requested by the Underwriter in such Underwritten Offering;

3.1.18 file the applicable Registration Statement with FINRA within three (3) Business Days of the date such Registration Statement is filed with or submitted to the SEC, and cooperate with each participating Holder and Underwriter, if any, and their respective counsels in connection with any other filings required to be made with FINRA; and

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

3.2 Registration Expenses. The Registration Expenses of all Registrations shall be borne by the Company. It is acknowledged by the Holders that the Holders shall bear all Underwriters’ commissions and discounts, brokerage fees, Underwriter marketing costs, transfer taxes and, other than as set forth in the definition of “Registration Expenses,” all fees and expenses of any legal counsel representing the Holders.

3.3 Requirements for Participation in Registration Statement in Offerings. Notwithstanding anything in this Agreement to the contrary, if any Holder does not provide the Company with its requested Holder Information, the Company may exclude such Holder’s Registrable Securities from the applicable Registration Statement or Prospectus if the Company determines, based on the advice of counsel, that such information is necessary to effect the registration and such Holder continues thereafter to withhold such information. No person or entity may participate in any Underwritten Offering or other offering for equity securities of the Company pursuant to a Registration initiated by the Company hereunder unless such person or entity (i) agrees to sell such person’s or entity’s securities on the basis provided in any underwriting, sales, distribution or placement arrangements approved by the Company and (ii) completes and executes all customary questionnaires, powers of attorney, indemnities, lock-up agreements, underwriting or other agreements and other customary documents as may be reasonably required under the terms of such underwriting, sales, distribution or placement arrangements. The exclusion of a Holder’s Registrable Securities as a result of this Section 3.3 shall not affect the registration of the other Registrable Securities to be included in such Registration.

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

3.4.1 Upon receipt of written notice from the Company that: (a) a Registration Statement or Prospectus contains a Misstatement; or (b) any request by the Commission for any amendment or supplement to any Registration Statement or Prospectus or for additional information or of the occurrence of an event requiring the preparation of a supplement or amendment to such Prospectus so that, as thereafter delivered to the purchasers of the securities covered by such Registration Statement or Prospectus, such Registration Statement or Prospectus will not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, each of the Holders shall forthwith discontinue disposition of Registrable Securities pursuant to such Registration Statement covering such Registrable Securities until it has received copies of a supplemented or amended Prospectus (it being understood that the Company hereby covenants to prepare and file such supplement or amendment as soon as practicable after the time of such notice) or until it is advised in writing by the Company that the use of the Prospectus may be resumed, and, if so directed by the Company, each such Holder will deliver to the Company all copies, other than permanent file copies then in such Holder’s possession, of the most recent Prospectus covering such Registrable Securities at the time of receipt of such notice. In the event that a Holder exercises a demand right pursuant to Section 2.1 and the related offering is expected to, or may, occur during a quarterly earnings blackout period of the Company (such blackout periods determined in accordance with the Company’s written insider trading compliance program adopted by the Board), the Company and such Holder shall act reasonably and work cooperatively in view of such quarterly earnings blackout period.

3.4.2 Subject to Section 3.4.4, if the filing, initial effectiveness or continued use of a Registration Statement in respect of any Registration at any time would (a) require the Company to make an Adverse Disclosure or (b) require the inclusion in such Registration Statement of financial statements that are unavailable to the Company for reasons beyond the Company’s control after the exercise by the Company of reasonable best efforts, or (c) in the good faith judgment of the majority of the Board, be seriously detrimental to the Company and as a result it is essential to defer such filing, initial effectiveness or continued use at such time, the Company may, upon giving prompt written notice of such action to the Holders, delay the filing or initial effectiveness of, or suspend use of, such Registration Statement for the shortest period of time determined in good faith by the Company to be necessary for such purpose. In the event the Company exercises its rights under this Section 3.4.2, the Holders agree to suspend, immediately upon their receipt of the notice referred to above, their use of the Prospectus relating to any Registration in connection with any sale or offer to sell Registrable Securities until such Holder receives written notice from the Company that such sales or offers of Registrable Securities may be resumed, and in each case maintain the confidentiality of such notice and its contents.

3.4.3 (a) During the period starting with the date thirty (30) days prior to the Company’s good faith estimate of the date of the filing of, and ending on a date ninety (90) days after the effective date of, a Company-initiated Registration, and provided that the Company continues to actively employ, in good faith, all reasonable efforts to maintain the effectiveness of the applicable Shelf, the Company may, upon giving prompt written notice of such action to the Holders, delay any other registered offering pursuant to Section 2.1.4 and, (b) during the period starting with the date fifteen (15) days prior to the Company’s good faith estimate of the date of the filing of, and ending on a date forty five (45) days after the effective date of, a Company-initiated Registration, and provided that the Company continues to actively employ, in good faith, all reasonable efforts to maintain the effectiveness of the applicable Shelf, the Company may, upon giving prompt written notice of such action to the Holders, delay any other registered offering pursuant to Section 2.4.

3.4.4 The right to delay or suspend any filing, initial effectiveness or continued use of a Registration Statement pursuant to Section 3.4.2 or a registered offering pursuant to Section 3.4.3 shall be exercised by the Company, in the aggregate, on not more than ninety (90) consecutive calendar days, or for more than one hundred and twenty (120) total calendar days, in each case during any twelve-month period.

3.5 Reporting Obligations. As long as any Holder shall own Registrable Securities, the Company, at all times while it shall be a reporting company under the Exchange Act, covenants to file timely (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to Sections 13(a) or 15(d) of the Exchange Act and to promptly furnish the Holders with true and complete copies of all such filings; provided that any documents publicly filed or furnished with the Commission pursuant to the Electronic Data Gathering, Analysis and Retrieval System shall be deemed to have been furnished or delivered to the Holders pursuant to this Section 3.5. The Company further covenants that it shall (i) take such further action as any Holder may reasonably request, all to the extent required from time to time to enable such Holder to sell shares of Common Stock held by such Holder without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act (or any successor rule then in effect) and (ii) certify to the Holders in writing that it has filed current Form 10 information with the Commission within four (4) Business Days of the Closing. Upon the request of any Holder, the Company shall deliver to such Holder a written certification of a duly authorized officer as to whether it has complied with such requirements.

ARTICLE IV

INDEMNIFICATION AND CONTRIBUTION

4.1 Indemnification.

4.1.1 The Company agrees to indemnify, to the extent permitted by law, each Holder of Registrable Securities, its officers, directors, partners, members and agents and each person or entity who controls such Holder (within the meaning of the Securities Act), against all losses, claims, damages, liabilities and out-of-pocket expenses (including, without limitation, reasonable outside attorneys’ fees and reasonable expenses of investigation) arising out of, resulting from or based upon any untrue or alleged untrue statement of material fact contained in or incorporated by reference in any Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as the same are caused by or contained in any information or affidavit so furnished in writing to the Company by such Holder expressly for use therein. The Company shall indemnify the Underwriters, their officers and directors and each person or entity who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided in the foregoing with respect to the indemnification of the Holder.

4.1.2 In connection with any Registration Statement in which a Holder of Registrable Securities is participating, such Holder shall furnish (or cause to be furnished) to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such Registration Statement or Prospectus (the “Holder Information”) and, to the extent permitted by law, shall indemnify the Company, its directors, officers, partners, members and agents and each person or entity who controls the Company (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and out-of-pocket expenses (including, without limitation, reasonable outside attorneys’ fees and reasonable expenses of investigation) arising out of, resulting from or based upon any untrue or alleged untrue statement of material fact contained or incorporated by reference in any Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement is contained in (or not contained in, in the case of an omission) any Holder Information so furnished in writing by or on behalf of such Holder expressly for use therein; provided, however, that the obligation to indemnify shall be several, not joint and several, among such Holders of Registrable Securities, and the liability of each such Holder of Registrable Securities shall be in proportion to and limited to the net proceeds actually received by such Holder from the sale of Registrable Securities pursuant to such Registration Statement. The Holders of Registrable Securities shall indemnify the Underwriters, their officers, directors and each person or entity who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided in the foregoing with respect to indemnification of the Company.

4.1.3 Any person or entity entitled to indemnification herein shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s or entity’s right to indemnification hereunder to the extent such failure has not materially prejudiced the indemnifying party) and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Article IV for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation, unless (1) such indemnified party reasonably objects to such assumption on the grounds that there may be defenses available to it which are different from or in addition to the defenses available to such indemnifying party, (2) the indemnifying party shall have failed within a reasonable period of time to assume such defense or, having assumed such defense, has not conducted the defense of such claim actively and diligently or (3) the named parties in any such proceeding (including any impleaded parties) include both the indemnified party and the indemnifying party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interest between them, in which case the indemnified party shall be promptly reimbursed by the indemnifying party for the expenses incurred in connection with retaining one separate legal counsel, in addition to any local counsel (for the avoidance of doubt, for all indemnified parties in connection therewith). If such defense is assumed, (A) the indemnifying party shall keep the indemnified party informed as to the status of such claim at all stages thereof (including all settlement negotiations and offers), promptly submit to such indemnified party copies of all pleadings, responsive pleadings, motions and other similar legal documents and paper received or filed in connection therewith, permit such indemnified party and their respective counsels to confer with the indemnifying party and its counsel with respect to the conduct of the defense thereof, and permit indemnified party and its counsel a reasonable opportunity to review all legal papers to be submitted prior to their submission and (B) the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent shall not be unreasonably withheld). In any action hereunder as to which the indemnifying party has assumed the defense thereof with counsel satisfactory to the indemnified party, the indemnified party shall continue to be entitled to participate in the defense thereof, with counsel of its own choice, but the indemnifying party shall not be obligated hereunder to reimburse the indemnified party for the costs thereof. No indemnifying party shall, without the prior written consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement includes a statement or admission of fault, culpability or failure to act on the part of such indemnified party or which settlement does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation that shall be in form and substance satisfactory to such indemnified party.

4.1.4 The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling person or entity of such indemnified party and shall survive the transfer of securities.

4.1.5 If the indemnification provided under Section 4.1 from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and out-of-pocket expenses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities and out-of-pocket expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by (or not made by, in the case of an omission), or relates to information supplied by (or not supplied by in the case of an omission), such indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action; provided, however, that the liability of any Holder under this Section 4.1.5 shall be limited to the amount of the net proceeds actually received by such Holder in such offering giving rise to such liability. The amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include, subject to the limitations set forth in Sections 4.1.1, 4.1.2 and 4.1.3 above, any legal or other fees, charges or out-of-pocket expenses reasonably incurred by such party in connection with any investigation or proceeding. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 4.1.5 were determined by pro rata allocation or by any other method of allocation, which does not take account of the equitable considerations referred to in this Section 4.1.5. No person or entity guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this Section 4.1.5 from any person or entity who was not guilty of such fraudulent misrepresentation.

4.1.6 The obligations of the parties under this Article IV shall be in addition to any liability which any party may otherwise have to any other party.

Notwithstanding anything herein to the contrary, any provision hereof may be waived by any waiving party on such party’s own behalf, without the consent of any other party.

5.7 Other Registration Rights. Other than as provided in the Subscription Agreements, the Company represents and warrants that no person or entity, other than a Holder of Registrable Securities, has any right to require the Company to register any securities of the Company for sale or to include such securities of the Company in any Registration Statement filed by the Company for the sale of securities for its own account or for the account of any other person or entity. For so long as (a) the Sponsor and its affiliates hold, in the aggregate, at least one percent (1%) of the outstanding shares of Class A Common Stock, the Company hereby agrees and covenants that it will not grant rights to register any Common Stock (or securities convertible into or exchangeable for Common Stock) pursuant to the Securities Act that are more favorable, pari passu or senior to those granted to the Holders hereunder (such rights “Competing Registration Rights”) without the prior written consent of the Sponsor, (b) an Investor Stockholder and its affiliates hold, in the aggregate, at least one percent (1%) of the outstanding shares of Class A Common Stock, the Company hereby agrees and covenants that it will not grant Competing Registration Rights without the prior written consent of such Investor Stockholder, and (c) a ProKidney Holder and its affiliates hold, in the aggregate, at least one percent (1%) of the outstanding shares of Class A Common Stock, the Company hereby agrees and covenants that it will not grant Competing Registration Rights without the prior written consent of such ProKidney Holder. Further, the Company represents and warrants that this Agreement supersedes any other registration rights agreement or agreement with similar terms and conditions and in the event of a conflict between any such agreement or agreements and this Agreement, the terms of this Agreement shall prevail.

5.8 Term. This Agreement shall terminate on the earlier of (a) the tenth (10^th) anniversary of the date of this Agreement and (b) with respect to any Holder, on the date that such Holder no longer holds any Registrable Securities. The provisions of Sections 3.2 and 3.5 and Articles IV and V shall survive any termination.

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

5.10 Additional Holders; Joinder. In addition to persons or entities who may become Holders pursuant to Section 5.2, subject to the prior written consent of each of the Sponsor, each ProKidney Holder and each Investor Stockholder (in each case, so long as such Holder and its affiliates hold, in the aggregate, at least one percent (1%) of the outstanding shares of Class A Common Stock), the Company may make any person or entity who acquires Class A Common Stock or rights to acquire Class A Common Stock after the date hereof a party to this Agreement (each such person or entity, an “Additional Holder”) by obtaining an executed joinder to this Agreement from such Additional Holder in the form of Exhibit A attached hereto (a “Joinder”). Such Joinder shall specify the rights and obligations of the applicable Additional Holder under this Agreement. Upon the execution and delivery and subject to the terms of a Joinder by such Additional Holder, the Class A Common Stock then owned, or underlying any rights then owned, by such Additional Holder (the “Additional Holder Common Stock”) shall be Registrable Securities to the extent provided herein and therein and such Additional Holder shall be a Holder under this Agreement with respect to such Additional Holder Common Stock.

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

5.12 Specific Performance. Each of the parties acknowledges and agrees that the other parties would be damaged irreparably in the event any of the provisions of this Agreement are not performed in accordance with their specific terms or otherwise are breached or violated. Accordingly, to the fullest extent permitted by law, each of the parties agrees that, without posting bond or other undertaking, the other parties will be entitled to an injunction or injunctions to prevent breaches or violations of the provisions of this Agreement and to enforce specifically this Agreement and the terms and provisions hereof in any action, claim or suit in addition to any other remedy to which it may be entitled, at law or in equity. Each party further agrees that, in the event of any action for specific performance in respect of such breach or violation, it will not assert that the defense that a remedy at law would be adequate.

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

EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (I) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (II) EACH SUCH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (III) EACH SUCH PARTY MAKES THIS WAIVER VOLUNTARILY, AND (IV) EACH SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 3(c).

(d) Assignment; Third Parties. This Agreement and all of the provisions hereof will be binding upon and inure to the benefit of the parties hereto and their respective heirs, successors and permitted assigns. This Agreement and all obligations of a Holder are personal to such Holder and may not be transferred or delegated at any time. Nothing contained in this Agreement shall be construed to confer upon any person who is not a signatory hereto any rights or benefits, as a third party beneficiary or otherwise.

(e) Specific Performance. Each Holder acknowledges that its obligations under this Agreement are unique, recognizes and affirms that in the event of a breach of this Agreement by such Holder, money damages will be inadequate and the Company will have no adequate remedy at law, and agrees that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed by such Holder in accordance with their specific terms or were otherwise breached. Accordingly, the Company shall be entitled to an injunction or restraining order to prevent breaches of this Agreement by a Holder and to enforce specifically the terms and provisions hereof, without the requirement to post any bond or other security or to prove that money damages would be inadequate, this being in addition to any other right or remedy to which such party may be entitled under this Agreement, at law or in equity.

(f) Amendment; Waiver. Upon (i) the approval of a majority of the total number of directors serving on the Board of Directors of the Company and (ii) the written consent of the Holders of a majority of the total Lock-Up Shares, compliance with any of the provisions, covenants and conditions set forth in this Agreement may be waived by the Company, or any of such provisions, covenants or conditions may be amended or modified, so long as no Holder is impacted disproportionately than any other Holder by such waiver, amendment or modification; provided, however, that notwithstanding the foregoing, any amendment hereto or waiver hereof that adversely affects a Holder, solely in its capacity as a holder of Lock-Up Shares, shall require the consent of the Holder so affected. No course of dealing between any Holder or the Company and any other party hereto or any failure or delay on the part of a Holder or the Company in exercising any rights or remedies under this Agreement shall operate as a waiver of any rights or remedies of any Holder or the Company. No single or partial exercise of any rights or remedies under this Agreement by a party shall operate as a waiver or preclude the exercise of any other rights or remedies hereunder or thereunder by such party.

(g) Interpretation. The titles and subtitles used in this Agreement are for convenience only and are not to be considered in construing or interpreting this Agreement. In this Agreement, unless the context otherwise requires: (i) any pronoun used in this Agreement shall include the corresponding masculine, feminine or neuter forms, and the singular form of nouns, pronouns and verbs shall include the plural and vice versa; (ii) “including” (and with correlative meaning “include”) means including without limiting the generality of any description preceding or succeeding such term and shall be deemed in each case to be followed by the words “without limitation”; (iii) the words “herein,” “hereto,” and “hereby” and other words of similar import in this Agreement shall be deemed in each case to refer to this Agreement as a whole and not to any particular section or other subdivision of this Agreement; and (iv) the term “or” means “and/or”. The parties have participated jointly in the negotiation and drafting of this Agreement. Consequently, in the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties hereto, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provision of this Agreement.

(h) Notices. All notices and other communications among the parties hereto shall be in writing and shall be deemed to have been duly given (i) when delivered in person, (ii) when delivered after posting in the United States mail having been sent registered or certified mail return receipt requested, postage prepaid or (iii) when delivered by FedEx or other nationally recognized overnight delivery service, addressed, if to the Company, to: ProKidney Corp., 2000 Frontis Plaza Blvd, Suite 250, Winston-Salem, NC 27103, Attn: Investor Relations, email: elizabeth.goodwin@prokidney.com, with a copy, which shall not constitute notice, to Todd Girolamo, General Counsel, email: todd.girolamo@prokidney.com; and if to any Holder, at such Holder’s address or email address as set forth in the Company’s books and records.

(i) Severability. If any provision of this Agreement is held invalid or unenforceable by any court of competent jurisdiction, the other provisions of this Agreement will remain in full force and effect. Any provision of this Agreement held invalid or unenforceable only in part or degree will remain in full force and effect to the extent not held invalid or unenforceable.

(j) Entire Agreement. This Agreement constitutes the full and entire understanding and agreement among the parties with respect to the subject matter hereof, and any other written or oral agreement relating to the subject matter hereof existing between the parties is expressly canceled. Notwithstanding the foregoing, nothing in this Agreement (other than Section 2(f)) shall limit any of the rights, remedies or obligations of the Company or any of the Holders under any other agreement between any of the Holders and the Company, and nothing in any other agreement, certificate or instrument shall limit any of the rights, remedies or obligations of any of the Holders or the Company under this Agreement.

(k) Several Liability: The liability of any Holder hereunder is several (and not joint). Notwithstanding any other provision of this Agreement, in no event will any Holder be liable for any other Holder’s breach of such other Holder’s obligations under this Agreement.

(l) Counterparts. The undersigned hereby consents to receipt of this Agreement in electronic form and understands and agrees that this Agreement may be signed electronically. In the event that any signature is delivered by facsimile transmission, electronic mail or otherwise by electronic transmission evidencing an intent to sign this Agreement, such facsimile transmission, electronic mail or other electronic transmission shall create a valid and binding obligation of the undersigned with the same force and effect as if such signature were an original. Execution and delivery of this Agreement by facsimile transmission, electronic mail or other electronic transmission is legal, valid and binding for all purposes.
