Exhibit 10.1

Execution Copy

SUBSCRIPTION AGREEMENT

This SUBSCRIPTION AGREEMENT (this “Subscription Agreement”) is entered into on February 23, 2021, by and between one, a Cayman Islands exempted company (“AONE”), and the undersigned subscriber (the “Investor”).

WHEREAS, this Subscription Agreement is being entered into in connection with the Agreement and Plan of Merger, dated as of the date hereof (as may be amended, supplemented or otherwise modified from time to time, the “Transaction Agreement”), by and among AONE, MarkForged, Inc., a Delaware corporation (the “Company”), and Caspian Merger Sub Inc., a Delaware corporation (“Merger Sub”), pursuant to which, among other things, Merger Sub will merge with and into the Company, with the Company as the surviving company in the merger and, after giving effect to such merger, becoming a wholly owned subsidiary of AONE, and AONE will change its name to Markforged Holding Corporation, on the terms and subject to the conditions therein (the “Transaction”);

WHEREAS, prior to the closing of the Transaction (and as more fully described in the Transaction Agreement), AONE will domesticate as a Delaware corporation in accordance with Section 388 of the General Corporation Law of the State of Delaware and Part XII of the Cayman Islands Companies Law (2020 Revision) (the “Domestication”);

WHEREAS, in connection with the Transaction, AONE is seeking commitments from interested investors to purchase, following the Domestication and prior to the closing of the Transaction, shares of AONE’s Class A ordinary shares, par value $0.0001 per share, as such shares will exist as common stock in the Delaware corporation resulting from the Domestication (the “Shares”), in a private placement for a purchase price of $10.00 per share (the “Per Share Subscription Price”);

WHEREAS, the aggregate purchase price to be paid by the Investor for the subscribed Shares (as set forth on the signature page hereto) is referred to herein as the “Subscription Amount;” and

WHEREAS, substantially concurrently with the execution of this Subscription Agreement, AONE is entering into separate subscription agreements (the “Other Subscription Agreements”) with certain investors (the “Other Investors”) with an aggregate purchase price of $210,000,000 (inclusive of the Subscription Amount) (the “PIPE Investment”).

NOW, THEREFORE, in consideration of the foregoing and the mutual representations, warranties and covenants, and subject to the conditions, set forth herein, and intending to be legally bound hereby, each of the Investor and AONE acknowledges and agrees as follows:

1.            Subscription. The Investor hereby subscribes for and agrees to purchase from AONE, and AONE agrees to issue and sell to the Investor, the number of Shares set forth on the signature page of this Subscription Agreement on the terms and subject to the conditions provided for herein. The Investor acknowledges and agrees that, as a result of the Domestication, the Shares that will be issued pursuant hereto shall be shares of common stock in the Delaware corporation resulting from the Domestication (and not shares in a Cayman Islands exempted company).

2.            Closing. The closing of the sale of the Shares contemplated hereby (the “Closing,” and the date upon which the Closing occurs, the “Closing Date”) shall occur following the Domestication on the date of the closing of the Transaction substantially concurrent with, and contingent on, the consummation of the Transaction (such closing date of the Transaction, the “Transaction Closing Date”). Upon delivery of written notice from (or on behalf of) AONE to the Investor (the “Closing Notice”) that AONE 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 at least two (2) 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 AONE in the Closing Notice. On the Transaction Closing Date, AONE shall issue the number of Shares to be purchased hereunder to the Investor, and cause such Shares to be registered in book entry form in the name of the Investor on AONE’s share register, which book entry records shall be free and clear of any liens or other restrictions (other than those arising under this Subscription Agreement or applicable securities laws). 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 (for so long as AONE remains domiciled in the Cayman Islands) are authorized or required by law to close. Prior to or at the Closing, the Investor shall deliver to AONE 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 three (3) business days after the Transaction Closing Date specified in the Closing Notice, the Subscription Amount, to the extent paid, will promptly (but not later than two (2) business days thereafter) 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 8 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 be required to re-deliver to AONE the Subscription Amount following AONE’s delivery of a new Closing Notice).

3.            Closing Conditions.

(a)            The obligation of the parties hereto to consummate the purchase and sale of the Shares pursuant to this Subscription Agreement is subject to the following conditions: (i) no suspension of the qualification of the Shares for offering or sale or trading in any jurisdiction, or initiation or threatening of any proceedings for any of such purposes, shall have occurred; (ii) no governmental authority of competent jurisdiction shall have rendered, issued, promulgated, enforced or entered any judgment, order, law, rule or regulation (whether temporary, preliminary or permanent) which is then in effect and which then makes the consummation of the transactions contemplated hereby illegal or then restrains or prohibits the consummation of the transactions contemplated hereby, and (iii) all conditions precedent to the closing of the Transaction set forth in Sections 9.1(a), 9.1(b), 9.1(c), 9.1(d), 9.1(e) and 9.1(f) of the Transaction Agreement shall have been satisfied (as determined by the parties to the Transaction Agreement) or waived (other than those conditions which, by their nature, are to be satisfied at the closing of the Transaction).

(b)            The obligations of AONE to consummate the purchase and sale of the Shares pursuant to this Subscription Agreement is subject to the following additional conditions: (i) the representations and warranties made by the Investor 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 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 or similar qualification, all respects) as of such date, in each case without giving effect to the consummation of the Transactions and (ii) the Investor shall have performed, satisfied and complied in all material respects with all covenants, agreements and conditions required by this Subscription Agreement to be performed, satisfied or complied with by it at or prior to Closing.

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.

5.            AONE Representations and Warranties. AONE represents and warrants to the Investor, as of the date hereof and as of the Closing Date:

(a)            AONE 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). AONE 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. As of the Closing Date, following the Domestication, AONE will be duly incorporated, validly existing as a corporation and in good standing under the laws of the State of Delaware.

(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 and will not have been issued in violation of or subject to any preemptive or similar rights created under AONE’s organizational documents (as in effect at such time of issuance) or under the Delaware General Corporation Law or laws of the Cayman Islands, as the case may be.

(c)            This Subscription Agreement has been duly authorized, executed and delivered by AONE and, assuming that this Subscription Agreement constitutes the valid and binding agreement of the Investor, this Subscription Agreement is enforceable against AONE 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 execution, delivery and performance of this Subscription Agreement, including the issuance and sale by AONE 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 AONE 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 AONE or any of its subsidiaries is a party or by which AONE or any of its subsidiaries is bound or to which any of the property or assets of AONE is subject that would reasonably be expected to have a material adverse effect on the business, financial condition, stockholders’ equity or results of operations of AONE and its subsidiaries, taken as a whole (a “Material Adverse Effect”), or materially affect the validity of the Shares or the legal authority of AONE 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 AONE; 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 AONE 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 AONE 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 AONE with the U.S. Securities and Exchange Commission (the “SEC”) since August 21, 2020 (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. None of the SEC Reports filed under the Exchange Act included, when filed or, if amended, as of the date of such amendment with respect to those disclosures that are amended, any untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, that AONE makes no such representation or warranty with respect to any registration statement or any proxy statement/prospectus to be filed by AONE with respect to any information relating to the Company or any of its affiliates included in any SEC Report or filed as an exhibit thereto. As of the date hereof, there are no material outstanding or unresolved comments in comment letters received by AONE from the staff of the Division of Corporation Finance of the SEC with respect to any of the SEC Reports. The financial statements of AONE included in the SEC Reports comply in all material respects with applicable accounting requirements and the rules and regulations of the SEC with respect thereto as in effect at the time of filing and fairly present in all material respects the financial position of AONE as of and for the dates thereof and the results of operations and cash flows for the periods then ended, subject, in the case of unaudited statements, to normal, year-end audit adjustments. A copy of each SEC Report is available to the Investor via the SEC’s EDGAR system. AONE has timely filed each report, statement, schedule, prospectus, and registration statement that AONE was required to file with the SEC since its initial registration of the Class A ordinary shares with the SEC.

(f)            As of the date hereof, the authorized share capital of AONE is $22,100.00 divided into (i) 200,000,000 Class A ordinary shares, par value $0.0001 per share, of AONE, 21,500,000 of which are issued and outstanding as of the date hereof, (ii) 20,000,000 Class B ordinary shares, par value $0.0001 per share, of AONE, 5,375,000 of which are issued and outstanding as of the date hereof, and (iii) 1,000,000 preference shares, par value $0.0001 per share, of which no shares are issued and outstanding as of the date hereof ((i), (ii) and (iii) collectively, the “AONE Securities”).  The foregoing represents all of the issued and outstanding AONE Securities as of the date hereof.  All issued and outstanding AONE Securities (i) have been duly authorized and validly issued and are fully paid and non-assessable; (ii) have been offered, sold and issued in compliance with applicable law, including federal and state securities laws, and all requirements set forth in (1) AONE’s organizational documents, and (2) any other applicable contracts governing the issuance of such securities; and (iii) are not subject to, nor have they been issued in violation of, any purchase option, call option, right of first refusal, preemptive right, subscription right or any similar right under any provision of any applicable law, AONE’s organizational documents or any contract to which AONE is a party or otherwise bound.  As of the date hereof, warrants to purchase an aggregate of 8,525,000 AONE ordinary shares are issued and outstanding.  The warrants are not exercisable until the later of (x) August 20, 2021 and (y) thirty (30) days after the Closing Date. Except as set forth above and pursuant to the Other Subscription Agreements and the Transaction Agreement, there are no outstanding options, warrants or other rights to subscribe for, purchase or acquire from AONE any AONE Securities or other equity interests in AONE, or securities convertible into or exchangeable or exercisable for such equity interests. There are no securities or instruments issued by or to which AONE is a party containing anti-dilution or similar provisions that will be triggered by the issuance of (i) the Shares or (ii) the shares to be issued pursuant to any Other Subscription Agreement, that have not been or will not be validly waived on or prior to the Closing Date, including such provisions in Class B Shares pursuant to the terms of AONE’s memorandum of association.

(g)            AONE 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 12 of this Subscription Agreement, (iv) those required by the NYSE, including with respect to obtaining approval of AONE’s stockholders, (v) any filings required under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 or similar antitrust laws, and (vi) the failure of which to obtain would not be reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect.

(h)            AONE is in compliance with all applicable laws, except where such non-compliance would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect. AONE has not received any written communication from a governmental authority that alleges that AONE 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.

(i)            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 AONE to the Investor and the Shares 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.

(j)            Neither AONE 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.

(k)            As of the date hereof, the issued and outstanding Class A ordinary shares of AONE are registered pursuant to Section 12(b) of the Exchange Act and are listed for trading on the NYSE. Following the Domestication, the Shares will be registered under the Exchange Act and listed for trading on the NYSE. There is no suit, action, proceeding or investigation pending or, to the knowledge of AONE, threatened against AONE by the NYSE or the SEC with respect to any intention by such entity to deregister the Shares or prohibit or terminate the listing of the Shares on the NYSE, excluding, for the purposes of clarity, the customary ongoing review by the NYSE in connection with the Transaction and any action in connection with the pre-Domestication Class A ordinary shares of AONE in connection with the Domestication.

(l)            AONE 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).

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

(n)            Other than the Other Subscription Agreements, the Transaction Agreement and any other agreement contemplated by the Transaction Agreement, AONE has not entered into any side letter or similar agreement with any Other Investor in connection with such Investor’s direct or indirect investment in AONE or with any Other Investor. 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 than the terms of this Subscription Agreement, other than terms particular to the regulatory requirements of such subscriber or its affiliates or related funds, and such Other Subscription Agreements have not been amended or modified in any material respect following the date of this Subscription Agreement.

(o)            AONE acknowledges and agrees that, notwithstanding anything herein to the contrary, the Shares may be pledged by the Investor in connection with a bona fide margin agreement, which shall not be deemed to be a transfer, sale or assignment of the Shares hereunder, and the Investor effecting a pledge of Shares shall not be required to provide AONE with any notice thereof or otherwise make any delivery to AONE pursuant to this Agreement. AONE hereby agrees to execute and deliver such documentation as a pledgee of the Shares may reasonably request in connection with a pledge of the Shares to such pledgee by the Investor.

6.            Investor Representations and Warranties. The Investor represents and warrants to AONE, as of the date hereof and as of the Closing Date:

(a)            The Investor (i) is a “qualified institutional buyer” (as defined in Rule 144A under the Securities Act) or an institutional “accredited investor” (within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act), in each case, satisfying the applicable requirements set forth on Schedule A, (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). The Investor 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).

The Investor 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 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 AONE. The Investor further acknowledges that there have been no representations, warranties, covenants and agreements made to the Investor by or on behalf of AONE, 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 AONE expressly set forth in this Subscription Agreement.

(d)            The Investor acknowledges and agrees that the Investor has received such information as the Investor deems necessary in order to make an investment decision with respect to the Shares, including, with respect to AONE, the Transaction and the business of the Company and its subsidiaries. Without limiting the generality of the foregoing, the Investor acknowledges that it has reviewed AONE’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 full opportunity to 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. The Investor further acknowledges that the information provided to the Investor is preliminary and subject to change.

(e)            The Investor became aware of this offering of the Shares solely by means of direct contact between the Investor and AONE, the Company or a representative of AONE or the Company, and the Shares were offered to the Investor solely by direct contact between the Investor and AONE, the Company or a representative of AONE or the Company.

The Investor acknowledges that AONE represents and warrants 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 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, AONE, 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 AONE contained in this Subscription Agreement, in making its investment or decision to invest in AONE.

(f)            The Investor acknowledges that it is aware that there are substantial risks incident to the purchase and ownership of the Shares, including those set forth in AONE’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 AONE 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.

(g)            Alone, or together with any professional advisor(s), the Investor has had a full opportunity to ask questions of and receive answers from AONE or any person or persons acting on behalf of AONE concerning the terms and conditions of an investment in the Shares, 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 AONE. The Investor acknowledges specifically that a possibility of total loss exists.

(h)            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 AONE.

(i)            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.

(j)            The Investor, if not a natural person, 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.

(k)            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, if not a natural person, 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, if the Investor is a natural person, has legal competence and capacity to execute the same or, if the Investor is not a natural person, the signatory has been duly authorized to execute the same, and, assuming that this Subscription Agreement constitutes the valid and binding agreement of AONE, 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.

The Investor also represents that it maintains policies and procedures reasonably designed to ensure compliance with sanctions administered by the United States, to the extent applicable to it. The Investor further represents that, to the best of its knowledge 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.

(m)            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) it has not relied on AONE or any of its affiliates for investment advice or as the Plan’s fiduciary, with respect to its decision to acquire and hold the Shares, and none of the parties to the Transaction shall at any time be relied on 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.

(s)            The Investor acknowledges that the purchase and sale of Shares hereunder meets the exemptions from filing under FINRA Rule 5123(b)(1).

(t)            The Investor acknowledges that the Placement Agents may have acquired, or may acquire, non-public information with respect to AONE, which the Investor agrees need not be provided to it.

(u)            The Investor acknowledges and is aware that Goldman Sachs & Co. LLC is acting as financial advisor to AONE in connection with the Transaction.

7.            Registration Rights.

(a)            AONE agrees that, within thirty (30) calendar days following the Closing Date (such deadline, the “Filing Deadline”), AONE will submit to or file with the SEC a registration statement on Form S-1 or Form S-3 (if AONE 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 Agreement (the “Registrable Shares”) and AONE 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 75^th calendar day (or 100th calendar day if the SEC notifies AONE that it will “review” the Registration Statement) following the Closing and (ii) the 5th business day after the date AONE 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 applicable date, the “Effectiveness Deadline”); provided, however, that AONE’s obligations to include the Registrable Shares in the Registration Statement are contingent upon the Investor furnishing in writing to AONE such information regarding the Investor or its permitted assigns, the securities of AONE 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 AONE to effect the registration of the Registrable Shares, and the Investor shall execute such documents in connection with such registration as AONE may reasonably request that are customary of a selling stockholder in similar situations, including providing that AONE 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. AONE will provide a draft of the Registration Statement to the Investor for review at least two (2) business days in advance of the filing of the Registration Statement. In no event shall the Investor be identified as a statutory underwriter in the Registration Statement unless required by the SEC; provided, that if the SEC requests that the Investor be identified as a statutory underwriter in the Registration Statement, the Investor will have an opportunity to withdraw from the Registration Statement. With respect to the information to be provided by the Investor pursuant to this Section 7(a), AONE shall request such information from the Investor at least five (5) business days prior to the anticipated filing date of the Registration Statement. Notwithstanding the foregoing, if the SEC prevents AONE from including any or all of the shares proposed to be registered under the Registration Statement due to limitations on the use of Rule 415 of the Securities Act for the resale of the Shares by the applicable stockholders or otherwise, such Registration Statement shall register for resale such number of Shares which is equal to the maximum number of Shares as is permitted by the SEC. In such event, the number of Shares to be registered for each selling stockholder named in the Registration Statement shall be reduced pro rata among all such selling stockholders and as promptly as practicable after being permitted to register additional Shares under Rule 415 under the Securities Act, AONE shall amend the Registration Statement or file a new Registration Statement to register such Shares not included in the initial Registration Statement and cause such amendment or Registration Statement to become effective as promptly as practicable. For as long as the Investor holds Shares, AONE 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 AONE to file the Registration Statement by the Filing Deadline or to effect such Registration Statement by the Effectiveness Deadline shall not otherwise relieve AONE of its obligations to file or effect the Registration Statement as set forth above in this Section 7.

(b)            At its expense AONE shall:

(i)            except for such times as AONE 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 AONE 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 earliest 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 AONE to be in compliance with the current public information required under Rule 144(c)(1) (or Rule 144(i)(2), if applicable), and (C) three (3) years from the date of effectiveness of the Registration Statement. The period of time during which AONE 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 promptly as reasonably practicable:

(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 the effectiveness of any Registration Statement or the initiation of any proceedings for such purpose;

(3)            of the receipt by AONE 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, AONE shall not, when so advising the Investor of such events, provide the Investor with any material, nonpublic information regarding AONE other than to the extent that providing notice to the Investor of the occurrence of the events listed in (1) through (4) above may constitute material, nonpublic information regarding AONE;

(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 7(b)(ii)(4) above, except for such times as AONE is permitted hereunder to suspend, and has suspended, the use of a prospectus forming part of a Registration Statement, AONE shall use its commercially reasonable efforts to as soon as reasonably practicable prepare a post-effective amendment to such Registration Statement or a supplement to the related prospectus, or file any other required document so that, as thereafter delivered to purchasers of the Registrable 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 each securities exchange or market, if any, on which the shares of common stock issued by AONE 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 Agreement, in connection with the registration of the Registrable Shares.

(c)            Notwithstanding anything to the contrary in this Subscription Agreement, AONE shall be entitled to delay the filing or effectiveness of, or suspend the use of, the Registration Statement if (i) it determines, upon the advice of external legal counsel, that in order for the Registration Statement not to contain a material misstatement or omission, 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 (ii) the negotiation or consummation of a transaction by AONE or its subsidiaries is pending or an event has occurred, which negotiation, consummation or event AONE’s board of directors, upon the advice of external legal counsel, reasonably believes would require additional disclosure by AONE in the Registration Statement of material information that AONE 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 AONE’s board of directors, upon the advice of external legal counsel, to cause the Registration Statement to fail to comply with applicable disclosure requirements (each such circumstance, a “Suspension Event”); provided, however, that AONE may not delay or suspend the Registration Statement on more than two (2) occasions or for more than seventy-five (75) consecutive calendar days, or more than one hundred (100) total calendar days in each case during any twelve-month period. Upon receipt of any written notice from AONE 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 AONE 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 AONE 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 AONE unless otherwise required by law or subpoena. If so directed by AONE, the Investor will deliver to AONE 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.

The Investor may deliver written notice (an “Opt-Out Notice”) to AONE requesting that Investor not receive notices from AONE otherwise required by this Section 7; provided, however, that Investor may later revoke any such Opt-Out Notice in writing. Following receipt of an Opt-Out Notice from Investor (unless subsequently revoked), (i) AONE shall not deliver any such notices to Investor and Investor shall no longer be entitled to the rights associated with any such notice and (ii) each time prior to Investor’s intended use of an effective Registration Statement, Investor will notify AONE in writing at least two (2) business days in advance of such intended use, and if a notice of a Suspension Event was previously delivered (or would have been delivered but for the provisions of this Section 7) and the related suspension period remains in effect, AONE will so notify Investor, within one (1) business day of Investor’s notification to AONE, by delivering to Investor a copy of such previous notice of Suspension Event, and thereafter will provide Investor with the related notice of the conclusion of such Suspension Event promptly following its availability.

(d)            Indemnification.

(i)            AONE agrees to indemnify, to the extent permitted by law, the Investor (to the extent a seller under the Registration Statement), its directors, officers, employees, advisors and agents, 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) 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 AONE 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 AONE in writing such information and affidavits as AONE reasonably requests for use in connection with any such Registration Statement or Prospectus and, to the extent permitted by law, shall indemnify AONE, its directors and officers and each person or entity who controls AONE (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 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.

(v)            If the indemnification provided under this Section 7(d) 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. 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 7(d)(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 7(d)(v) from any person or entity who was not guilty of such fraudulent misrepresentation. Each indemnifying party’s obligation to make a contribution pursuant to this Section 7(d)(v) shall be individual, not joint and several, and in no event shall the liability of the Investor exceed the pre-tax net proceeds received by such Investor from the sale of Registrable Shares giving rise to such indemnification obligation.

(e)            In addition, in connection with any sale, assignment, transfer or other disposition of the Shares by the Investor pursuant to Rule 144 or pursuant to any other exemption under the Securities Act such that the Shares held by the Investor become freely tradable and upon compliance by the Investor with the requirements of this Subscription Agreement, if requested by the Investor, AONE shall cause the transfer agent for the Shares (the “Transfer Agent”) to remove any restrictive legends related to the book entry account holding such Shares and make a new entry for such book entry Shares sold or disposed of without restrictive legends within two (2) trading days of any such request therefor from the Investor, provided that AONE and the Transfer Agent have timely received from the Investor customary representations and other documentation reasonably acceptable to AONE and the Transfer Agent in connection therewith. Subject to receipt from the Investor by AONE and the Transfer Agent of customary representations and other documentation reasonably acceptable to AONE and the Transfer Agent in connection therewith, including, if required by the Transfer Agent, an opinion of AONE’s counsel, in a form reasonably acceptable to the 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 AONE remove any legend from the book entry position evidencing its Shares following the earliest of such time as such Shares are (i) being sold or transferred pursuant to an effective registration statement, or (ii) in connection with a sale pursuant to Rule 144. With respect to clause (i), while the Registration Statement is effective, AONE shall cause its counsel, or counsel acceptable to the Transfer Agent, to issue to the Transfer Agent a “blanket” legal opinion covering sales made pursuant to the registration statement in accordance with the provisions of this Section 7 to allow the legend to be removed upon such sale. AONE shall be responsible for the fees of its Transfer Agent and all DTC fees associated with such issuance.

8.            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, or are not capable of being satisfied on or prior to, the Closing and, as a result thereof, the transactions contemplated by this Subscription Agreement are not consummated at the Closing; and (d) October 29, 2021, if the Closing has not occurred on or before such date; provided that nothing herein will relieve any party from liability for any willful breach hereof prior to the time of termination, and each party will be entitled to any remedies at law or in equity to recover reasonable and documented out-of pocket losses, liabilities or damages arising from any such willful breach. AONE shall notify the Investor of the termination of the Transaction Agreement promptly after the termination of such agreement. Upon the termination of this Subscription Agreement in accordance with this Section 8, any monies paid by the Investor to AONE in connection herewith shall be promptly (and in any event within one business day after such termination) returned to the Investor without any deduction for or on account of any tax, withholding, charges, or set-off.

9.            Investor Covenant. Investor hereby agrees that, from the date of this Subscription Agreement, none of Investor or any person or entity acting on behalf of Investor or pursuant to any understanding with Investor will engage in any Short Sales with respect to securities of AONE prior to the Closing. For purposes of this Section 9 “Short Sales” shall include, without limitation, all “short sales” as defined in Rule 200 promulgated under Regulation SHO under the Exchange Act, and all types of direct and indirect stock pledges (other than pledges in the ordinary course of business as part of prime brokerage arrangements), forward sale contracts, options, puts, calls, swaps and similar arrangements (including on a total return basis), and sales and other transactions through non-U.S. broker dealers or foreign regulated brokers. Notwithstanding the foregoing, (i) nothing herein shall prohibit other entities under common management with Investor that have no knowledge of this Subscription Agreement or of Investor’s participation in the Transaction or PIPE Investment (including Investor’s controlled affiliates and/or affiliates) from entering into any Short Sales and (ii) in the case of an Investor that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Investor’s assets and the portfolio managers have no knowledge of the investment decisions made by the portfolio managers managing other portions of such Investor’s assets, the covenant set forth above shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the Shares covered by this Subscription Agreement.

10.            Trust Account Waiver. The Investor acknowledges that AONE is a blank check company with the powers and privileges to effect a merger, asset acquisition, reorganization or similar business combination involving AONE and one or more businesses or assets. The Investor further acknowledges that, as described in AONE’s prospectus relating to its initial public offering dated August 20, 2020 (the “IPO Prospectus”) available at www.sec.gov, substantially all of AONE’s assets consist of the cash proceeds of AONE’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 AONE, its public shareholders and the underwriter of AONE’s initial public offering. Except with respect to interest earned on the funds held in the Trust Account that may be released to AONE 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 AONE 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 (x) shall serve to limit or prohibit the Investor’s right to pursue a claim against AONE for legal relief against assets held outside the Trust Account, for specific performance or other equitable relief, (y) shall serve to limit or prohibit any claims that the Investor may have in the future against AONE’s assets or funds that are not held in the Trust Account (including any funds that have been released from the Trust Account and any assets that have been purchased or acquired with any such funds) or (z) 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 AONE 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 and the Investor’s rights under Section 7 hereof) 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 without AONE’s written consent, 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 AONE hereunder or any of AONE’s obligations may be transferred or assigned other than pursuant to the Transaction.

(b)            AONE may request from the Investor such additional information as AONE 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 promptly 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 AONE agrees to keep any such information provided by Investor confidential, except as may be required by applicable law, rule, regulation or in connection with any legal proceeding or regulatory request. The Investor acknowledges that AONE may file a copy of this Subscription Agreement with the SEC as an exhibit to a current or periodic report or a registration statement of AONE.

(c)            AONE acknowledges and agrees that the Placement Agents are third party beneficiaries of the acknowledgements, understandings, agreements, representations, warranties and covenants of the parties contained in this Subscription Agreement. The Investor acknowledges that AONE and the Placement Agents (as third party beneficiaries of Section 5, Section 6, Section 11 (to the extent applicable to the Placement Agents) and Section 12 hereof on their own behalf and not, for the avoidance of doubt, on behalf of AONE or the Company) 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 AONE and the Placement Agents if any of the representations and warranties of the Investor set forth herein are no longer accurate in any material respect.

(d)            AONE, the Placement Agents (to the extent set forth in Section 11(c)) 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 8 above) except by an instrument in writing, signed by each of the parties hereto. 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 7(d), Section 8(b), Section 11(c), and Section 11(d) with respect to the persons referenced therein (who shall be express third party beneficiaries of and entitled to enforce such provisions), 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)            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. Counterparts may be delivered via facsimile, electronic mail (including any electronic signature covered by the U.S. federal ESIGN Act of 2000, Uniform Electronic Transactions Act, the Electronic Signatures and Records Act or other applicable law, e.g., www.docusign.com) or other transmission method and any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes. All counterparts so executed and delivered shall be construed together and shall constitute one and the same agreement.

(k)            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 seek an injunction or injunctions to prevent breaches of this Subscription Agreement, without posting a bond or undertaking and without proof of damages, to enforce specifically the terms and provisions of this Subscription Agreement, this being in addition to any other remedy to which such party is entitled at law, in equity, in contract, in tort or otherwise.

(l)            THE PARTIES HERETO IRREVOCABLY SUBMIT TO THE EXCLUSIVE JURISDICTION OF THE COURT OF CHANCERY OF THE STATE OF DELAWARE (OR, TO THE EXTENT SUCH COURT DOES NOT HAVE SUBJECT MATTER JURISDICTION, THE SUPERIOR COURT OF THE STATE OF DELAWARE, OR THE UNITED STATES DISTRICT COURT FOR THE DISTRICT OF DELAWARE) SOLELY IN RESPECT OF THE INTERPRETATION AND ENFORCEMENT OF THE PROVISIONS OF THIS SUBSCRIPTION AGREEMENT AND THE DOCUMENTS REFERRED TO IN THIS SUBSCRIPTION AGREEMENT AND IN RESPECT OF THE TRANSACTIONS CONTEMPLATED HEREBY, AND HEREBY WAIVE, AND AGREE NOT TO ASSERT, AS A DEFENSE IN ANY ACTION, SUIT OR PROCEEDING FOR INTERPRETATION OR ENFORCEMENT HEREOF OR ANY SUCH DOCUMENT THAT IS NOT SUBJECT THERETO OR THAT SUCH ACTION, SUIT OR PROCEEDING MAY NOT BE BROUGHT OR IS NOT MAINTAINABLE IN SAID COURTS OR THAT VENUE THEREOF MAY NOT BE APPROPRIATE OR THAT THIS SUBSCRIPTION AGREEMENT OR ANY SUCH DOCUMENT MAY NOT BE ENFORCED IN OR BY SUCH COURTS, AND THE PARTIES HERETO IRREVOCABLY AGREE THAT ALL CLAIMS WITH RESPECT TO SUCH ACTION, SUIT OR PROCEEDING SHALL BE HEARD AND DETERMINED BY SUCH A DELAWARE STATE OR FEDERAL COURT. THE PARTIES HEREBY CONSENT TO AND GRANT ANY SUCH COURT JURISDICTION OVER THE PERSON OF SUCH PARTIES AND OVER THE SUBJECT MATTER OF SUCH DISPUTE AND AGREE THAT MAILING OF PROCESS OR OTHER PAPERS IN CONNECTION WITH SUCH ACTION, SUIT OR PROCEEDING IN THE MANNER PROVIDED IN SECTION 14 OF THIS SUBSCRIPTION AGREEMENT OR IN SUCH OTHER MANNER AS MAY BE PERMITTED BY LAW SHALL BE VALID AND SUFFICIENT SERVICE THEREOF. 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 REQUIRED THE APPLICATION OF THE LAW OF ANY OTHER STATE.

(m)            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.

15. Independent Obligations. The obligations of Investor under this Subscription Agreement are several and not joint with the obligations of any Other Investor under the Other Subscription Agreements, and Investor shall not be responsible in any way for the performance of the obligations of any Other Investor under the Other Subscription Agreements. The decision of Investor to purchase Shares pursuant to this Subscription Agreement has been made by Investor independently of any Other Investor and independently of any information, materials, statements or opinions as to the business, affairs, operations, assets, properties, liabilities, results of operations, condition (financial or otherwise) or prospects of AONE or any of its subsidiaries which may have been made or given by any Other Investor or by any agent or employee of any Other Investor, and neither Investor nor any of its agents or employees shall have any liability to any Other Investor (or any other person) relating to or arising from any such information, materials, statements or opinions. Nothing contained herein or in any Other Subscription Agreement, and no action taken by Investor or any Other Investors pursuant hereto or thereto, shall be deemed to constitute the Investor and Other Investors as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Investor and Other Investors are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by this Subscription Agreement and the Other Subscription Agreements. Investor acknowledges that no Other Investor has acted as agent for the Investor in connection with making its investment hereunder and no Other Investor will be acting as agent of the Investor in connection with monitoring its investment in the Shares or enforcing its rights under this Subscription Agreement. Investor shall be entitled to independently protect and enforce its rights, including without limitation the rights arising out of this Subscription Agreement, and it shall not be necessary for any Other Investor or investor to be joined as an additional party in any proceeding for such purpose.
