7.YOU ARE RELEASING AND WAIVING CLAIMS 
While it is very important that you read this entire Agreement carefully, it is especially important that you read this Section carefully, because it lists important rights you are giving up if you decide to enter into this Agreement.
Who And What Does The Release Cover? 
What Are You Giving Up? It is the Company’s position that you have no legitimate basis for bringing a legal action against it. You may agree or believe otherwise or simply not know.

Acquisition, Inc. (the “Company”), a Cayman Islands exempted company, which shall be domesticated as a Delaware corporation prior to the closing of the Transaction (as defined herein), and the undersigned subscriber
(“Subscriber”). 
 WHEREAS, concurrently with the execution of this Subscription Agreement, the Company is entering into a
definitive merger agreement with Micromidas, Inc., a Delaware corporation (“Micromidas”), and the other parties thereto, in substantially the form previously provided to Subscriber, providing for the acquisition by the Company of
Micromidas (as may be amended or supplemented from time to time, the “Transaction Agreement,” and the transactions contemplated by the Transaction Agreement, the “Transaction”); 

WHEREAS, prior to the closing of the Transaction, the Company will be domesticated as a Delaware corporation in accordance with
Section 388 of the General Corporation Law of the State of Delaware and deregister as a Cayman Islands exempted company in accordance with Section 206 of the Cayman Islands Companies Law (2020 Revision) (the
“Domestication”); 
 WHEREAS, in connection with the Transaction, Subscriber desires to subscribe for and purchase from the
Company, following the Domestication and immediately prior to the consummation of the Transaction, that number of shares of the Company’s Class A common stock, par value $0.0001 per share (the “Shares”), set forth on the
signature page hereto (the “Subscribed Shares”) for a purchase price of $10.00 per share (the “Per Share Price” and the aggregate of such Per Share Price for all Subscribed Shares being referred to herein as the
“Purchase Price”), and the Company desires to issue and sell to Subscriber the Subscribed Shares in consideration of the payment of the Purchase Price by or on behalf of Subscriber to the Company at or prior to the Closing Date (as
defined herein); and 
 WHEREAS, on or about the date of this Subscription Agreement, the Company is entering into subscription agreements
(the “Other Subscription Agreements” and together with the Subscription Agreement, the “Subscription Agreements”) with certain other investors (the “Other Subscribers” and together with Subscriber,
the “Subscribers”), pursuant to which such Subscribers have agreed to purchase on the closing date of the Transaction, inclusive of the Subscribed Shares, an aggregate amount of up to 20,000,000 Shares, at the Per Share Price. 

NOW, THEREFORE, in consideration of the foregoing and the mutual representations, warranties and covenants, and subject to the conditions,
herein contained, and intending to be legally bound hereby, the parties hereto hereby agree as follows: 

Section 1    Subscription. Subject to the terms and conditions hereof, at the Closing (as defined
below), Subscriber hereby agrees to subscribe for and purchase, and the Company hereby agrees to issue and sell to Subscriber, upon the payment of the Purchase Price, the Subscribed Shares (such subscription and issuance, the
“Subscription”). Subscriber acknowledges and agrees that, as a result of the Domestication, the Shares that will be purchased by Subscriber and issued by the Company pursuant hereto shall be shares of common stock in a Delaware
corporation (and not, for the avoidance of doubt, ordinary shares in a Cayman Islands exempted company). 

Section 2    Closing. 

(a)    The consummation of the Subscription contemplated hereby (the “Closing”) shall occur on the
closing date of the Transaction (the “Closing Date”), immediately prior to or substantially concurrently with the consummation of the Transaction. 

(b)    At least five (5) Business Days before the anticipated Closing Date, the Company shall deliver written notice
to Subscriber (the “Closing Notice”) specifying (i) the anticipated Closing Date and (ii) the wire instructions for delivery of the Purchase Price to the Company. No later than two (2) Business Days prior to the
Closing Date, Subscriber shall deliver the Purchase Price for the Subscribed Shares by wire transfer of United States dollars in immediately available funds to the account specified by the Company in the Closing Notice, such funds to be held by the
Company in escrow until the Closing, and deliver to the Company such information as is reasonably required in the Closing Notice in order for the Company to issue the Subscribed Shares to Subscriber, including,

 
without limitation, the legal name of the person in whose name the Subscribed Shares are to be issued and a duly completed and executed Internal Revenue Service Form W-9 or appropriate Form W-8.

Subscriber, the Company shall promptly (but in no event later than seven (7) Business Days after the anticipated Closing Date specified in the Closing Notice) return the funds so delivered by Subscriber to the Company by wire transfer in
immediately available funds to the account specified by Subscriber, and any book entries shall be deemed cancelled. Notwithstanding such return or cancellation (x) a failure to close on the anticipated Closing Date shall not, by itself, be
deemed to be a failure of any of the conditions to Closing set forth in this Section 2 to be satisfied or waived on or prior to the Closing Date, and (y) unless and until this Subscription Agreement is terminated in
accordance with Section 7 herein, Subscriber shall remain obligated (A) to redeliver funds to the Company in escrow following the Company’s delivery to Subscriber of a new Closing Notice and (B) to consummate

which commercial banks are required or authorized to close in the State of New York. Any funds held in escrow by the Company will be uninvested, and Subscriber shall not be entitled to any interest earned thereon. Upon delivery of the Subscribed
Shares to Subscriber (or its nominee or custodian, if applicable), the Purchase Price may be released by the Company from escrow. 

(c)    The Closing shall be subject to the satisfaction, or valid waiver by each of the parties hereto, of the conditions
that, on the Closing Date: 
  

	 	(i)	 no suspension of the qualification of the Subscribed Shares for offering or sale or trading in any

Section 3    Company Representations and Warranties. The Company represents and warrants to Subscriber
that: 
 (a)    The Company (i) is or will be, as applicable, duly organized, validly existing and in good standing
under the laws of the Cayman Islands as of the date hereof and the State of Delaware as of the Closing Date, (ii) has the requisite power and authority to own, lease and operate its properties, to carry on its business as it is now being
conducted and to enter into, deliver and perform its obligations under this Subscription Agreement, and (iii) is duly licensed or qualified to conduct its business and, if applicable, is in good standing under the laws of each jurisdiction
(other than its jurisdiction of incorporation) in which the conduct of its business or the ownership of its properties or assets requires such license or qualification, except, with respect to the foregoing clause (iii), where the failure to
be in good standing would not reasonably be expected to have a Company Material Adverse Effect. For purposes of this Subscription Agreement, a “Company Material Adverse Effect” means an event, change, development, occurrence,
condition or effect with respect to the Company and its subsidiaries, taken together as a whole (on a consolidated basis), that, individually or in the aggregate, would reasonably be expected to have a material adverse effect on the business,
financial condition, stockholders equity or results of operations of the Company and its subsidiaries, taken together as a whole (on a consolidated basis) or on the Company’s ability to consummate the transactions contemplated hereby, including
the issuance and sale of the Subscribed Shares. 
 (b)    As of the Closing Date, the Subscribed Shares will be duly
authorized and, when issued and delivered to Subscriber against full payment therefor in accordance with the terms of this Subscription Agreement, will be validly issued, fully paid and non-assessable and will
not have been issued in violation of any preemptive rights created under the Company’s organizational documents (as adopted on or prior to the Closing Date) or the laws of its jurisdiction of incorporation. 

(c)    This Subscription Agreement has been duly authorized, executed and delivered by the Company, and assuming the due
authorization, execution and delivery of the same by Subscriber, this Subscription Agreement shall constitute the valid and legally binding obligation of the Company, enforceable against the Company in accordance with its terms, except as such
enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium and similar laws affecting creditors generally and by the availability of equitable remedies. 

  
 3 

 (d)    Other than the Other Subscription Agreements, the Transaction
Agreement and any other agreement contemplated by the Transaction Agreement, the Company has not entered into any side letter or similar agreement in connection with the Transaction with any Other Subscriber or any other investor in connection with
such Other Subscriber’s or investor’s direct or indirect investment in the Company. Except for any alternative settlement procedures, eligibility for qualified purchasers to invest, and other than terms particular to the regulatory
requirements of such investor or its affiliates or related funds, no Other Subscription Agreement includes terms and conditions that are materially more favorable to any such Other Subscriber than Subscriber hereunder, and such Other Subscription
Agreements reflect the same Per Share Price. The Other Subscription Agreements have not been amended or modified and shall not be amended after the date hereof to provide for terms with respect to the purchase of Shares that are materially more
favorable to such Other Subscriber thereunder than the terms of this Subscription Agreement, unless such terms are also offered to Subscriber. 

(e)    Assuming the accuracy of the representations and warranties of Subscriber, the execution and delivery of this
Subscription Agreement, the issuance and sale of the Subscribed Shares and the compliance by the Company with the provisions of this Subscription Agreement and the consummation of the transactions contemplated herein will not conflict with or result
in a breach or violation of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition of any lien, charge or encumbrance upon any of the property or assets of the Company pursuant to the terms of
(i) any indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument to which the Company is a party or by which the Company is bound or to which any of the property or assets of the Company is subject;
(ii) the organizational documents of the Company; or (iii) any statute or any judgment, order, rule or regulation of any court or governmental agency or body, domestic or foreign, having jurisdiction over the Company or any of its
properties that, in the case of clauses (i) and (iii), would reasonably be expected to have a Company Material Adverse Effect. 

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

(g)    Assuming the accuracy of the representations and warranties of Subscriber, the Company is not required to obtain
any consent, waiver, authorization or order of, give any notice to, or make any filing or registration with, any court or other federal, state, local or other governmental authority, self-regulatory organization (including Nasdaq Capital Market (the
“Stock Exchange”)) or other person in connection with the execution, delivery and performance of this Subscription Agreement (including, without limitation, the issuance of the Subscribed Shares), other than (i) filings
required by applicable state securities laws, (ii) the filing of the Registration Statement pursuant to Section 5 below, (iii) the filing of a Notice of Exempt Offering of Securities on Form D with the United
States Securities and Exchange Commission (“Commission”) under Regulation D of the Securities Act of 1933, as amended (the “Securities Act”), if applicable, (iv) those required by the Stock Exchange, including
with respect to obtaining stockholder approval, (v) those required to consummate the Transaction as provided under the Transaction Agreement, (vi) the filing of notification under the Hart-Scott-Rodino Antitrust Improvements Act of 1976,
if applicable, and (vii) the failure of which to obtain would not be reasonably likely to have a Company Material Adverse Effect. 

(h)    As of their respective dates, all reports, statements, schedules, prospectuses or registration statements
(collectively, the “SEC Reports”) required to be filed by the Company with the Commission complied in all material respects with the applicable requirements of the Securities Act and/or the Securities Exchange Act of 1934, as
amended (the “Exchange Act”), and the rules and regulations of the Commission promulgated thereunder, and none of the SEC Reports, when filed, contained any untrue statement of a material fact or omitted to state a material fact
required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The financial statements of the Company included in the SEC Reports comply in all
material respects with applicable accounting requirements and the rules and regulations of the Commission with respect thereto as in effect at the time of filing and fairly present in all material respects the 

  
 4 

 financial position of the Company 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 Subscriber via the Commission’s EDGAR
system. The Company has timely filed each report, statement, schedule, prospectus, and registration statement that the Company was required to file with the Commission since its initial registration of the Class A ordinary shares with the
Commission. There are no material outstanding or unresolved comments in comment letters from the staff of the Division of Corporation Finance of the Commission with respect to any of the SEC Reports. 

(i)    Except for such matters that would not have a Company Material Adverse Effect, there is no (i) suit, action,
proceeding or arbitration before a governmental authority or arbitrator pending, or, to the knowledge of the Company, threatened in writing against the Company or (ii) judgment, decree, injunction, ruling or order of any governmental authority
or arbitrator outstanding against the Company. 
 (j)    Assuming the accuracy of Subscriber’s representations and
warranties set forth in Section 4 of this Subscription Agreement, no registration under the Securities Act is required for the offer and sale of the Subscribed Shares by the Company to Subscriber. 

(k)    Neither the Company nor any person acting on its behalf has engaged or will engage in any form of general
solicitation or general advertising (within the meaning of Regulation D) in connection with any offer or sale of the Subscribed Shares or any other action that would reasonably be expected to subject the offering, issuance or sale of any of the
Subscribed Shares to Subscriber pursuant to this Subscription Agreement to the registration requirements of the Securities Act. 

(l)    Except for Credit Suisse Securities (USA) LLC and Goldman Sachs & Co. LLC (the “Placement
Agents”), no broker or finder is entitled to any brokerage or finder’s fee or commission solely in connection with the sale of the Subscribed Shares to Subscriber. 

(m)    As of the date hereof, the Company’s Class A ordinary shares, as a class, are registered pursuant to
Section 12(b) of the Securities Exchange Act, and are listed for trading on the Stock Exchange under the symbol “AACQ.” There is no suit, action, proceeding or investigation pending or, to the knowledge of the Company, threatened
against the Company by the Stock Exchange or the Commission with respect to any intention by such entity to deregister the Class A ordinary shares or prohibit or terminate the listing of the Class A ordinary shares on the Stock Exchange.
The Company has taken no action that is designed to terminate the registration of the Class A ordinary shares under the Exchange Act. Following the Domestication, the Shares are expected to be registered under the Exchange Act and listed for
trading on the Stock Exchange. 
 (n)    As of the date of this Subscription Agreement and as of immediately prior to
the Closing Date (and without giving effect to the Domestication), the authorized capital stock of the Company consists of (i) 400,000,000 Class A ordinary shares, (ii) 50,000,000 Class B ordinary shares, par value of $0.0001 per share

Class B Shares are issued and outstanding, (iii) no Preference Shares are issued and outstanding, and (iv) 24,150,000 public warrants and 11,326,667 private placement warrants of the Company are issued and outstanding. All (i) issued
and outstanding Class A ordinary shares and Class B Shares have been duly authorized and validly issued, are fully paid and are non-assessable and are not subject to preemptive rights and
(ii) outstanding warrants have been duly authorized and validly issued and are not subject to preemptive rights. 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 the Company any Class A ordinary shares, Class B Shares or other equity interests in the Company, or securities convertible into or exchangeable or exercisable
for such equity interests. As of the date hereof the Company has no subsidiaries and does not own, directly or indirectly, interests or investments (whether equity or debt) in any person, whether incorporated or unincorporated. There are no
stockholder agreements, voting trusts or other agreements or understandings to which the Company is a party or by which it is bound relating to the voting of any securities of the Company, other than (A) as set forth in the SEC Reports and

 Section 4    Subscriber Representations and Warranties.
Subscriber represents and warrants to the Company that: 
 (a)    Subscriber (i) is duly organized, validly
existing and in good standing under the laws of its jurisdiction of organization, incorporation or formation, and (ii) has the requisite power and authority to enter into and perform its obligations under this Subscription Agreement. 

(b)    This Subscription Agreement has been duly executed and delivered by Subscriber, and assuming the due authorization,
execution and delivery of the same by the Company, this Subscription Agreement shall constitute the valid and legally binding obligation of Subscriber, enforceable against Subscriber in accordance with its terms, except as such enforceability may be
limited by bankruptcy, insolvency, reorganization, moratorium and similar laws affecting creditors generally and by the availability of equitable remedies. 

(c)    The execution and delivery of this Subscription Agreement, the purchase of the Subscribed Shares and the compliance
by Subscriber with the provisions of this Subscription Agreement and the consummation of the transactions contemplated herein will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default
under, or result in the creation or imposition of any lien, charge or encumbrance upon any of the property or assets of Subscriber pursuant to the terms of (i) any indenture, mortgage, deed of trust, loan agreement, lease, license or other
agreement or instrument to which Subscriber is a party or by which Subscriber is bound or to which any of the property or assets of Subscriber is subject; (ii) the organizational documents of Subscriber; or (iii) any statute or any
judgment, order, rule or regulation of any court or governmental agency or body, domestic or foreign, having jurisdiction over Subscriber or any of its properties that, in the case of clauses (i) and (iii), would reasonably be
expected to have a Subscriber Material Adverse Effect. For purposes of this Subscription Agreement, a “Subscriber Material Adverse Effect” means an event, change, development, occurrence, condition or effect with respect to
Subscriber that would reasonably be expected to have a material adverse effect on Subscriber’s ability to consummate the transactions contemplated hereby, including the purchase of the Subscribed Shares. 

(d)    Subscriber (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)(1), (2), (3) or (7) under the Securities Act), in each case, satisfying the applicable requirements set forth on Annex A, (ii) is acquiring the Subscribed Shares
only for its own account and not for the account of others, or if Subscriber is subscribing for the Subscribed Shares as a fiduciary or agent for one or more investor accounts, each owner of such account is a “qualified institutional
buyer” or an “accredited investor” (within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act), and Subscriber 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 Subscribed Shares with a view to, or for offer or sale in connection with, any
distribution thereof in violation of the Securities Act (and has provided the Company with the requested information on Annex A following the signature page hereto). Subscriber is not an entity formed for the specific purpose of acquiring the
Subscribed Shares and is an “institutional account” as defined by FINRA Rule 4512(c). 
 (e)    Subscriber
understands that the Subscribed Shares are being offered in a transaction not involving any public offering within the meaning of the Securities Act and that the Subscribed Shares have not been registered under the Securities Act. Subscriber
understands that the Subscribed Shares may not be offered, resold, transferred, pledged or otherwise disposed of by Subscriber absent an effective registration statement under the Securities Act, except (i) to the Company or a subsidiary
thereof, or (ii) pursuant to an applicable exemption from the registration requirements of the Securities Act, and, in each of cases (i) and (ii), in accordance with any applicable securities laws of the applicable states and other
jurisdictions of the United States, and that any certificates or book entry records representing the Subscribed Shares shall contain a restrictive legend to such effect. Subscriber acknowledges and agrees that the Subscribed Shares will be subject
to these securities law transfer restrictions and, as a result of these transfer restrictions, Subscriber may not be able to readily resell the Subscribed Shares and may be required to bear the financial risk of an investment in the Subscribed
Shares for an indefinite period of time. Subscriber acknowledges and agrees that the Subscribed Shares will not be eligible for offer, resale, transfer, pledge or disposition pursuant to Rule 144 promulgated under the Securities Act until at least
one year from the filing of “Form 10 information” with the Commission after the Closing Date. Subscriber understands that it has been advised to consult legal counsel prior to making any offer, resale, pledge or transfer of any of the
Subscribed Shares. 

  
 6 

 (f)    Subscriber understands and agrees that Subscriber is purchasing
the Subscribed Shares directly from the Company. Subscriber further acknowledges that there have not been, and Subscriber hereby agrees that it is not relying on, any representations, warranties, covenants or agreements made to Subscriber by the
Company, the Placement Agents, any of their respective affiliates or any control persons, officers, directors, employees, partners, agents or representatives, any other party to the Transaction or any other person or entity, expressly or by
implication, other than those representations, warranties, covenants and agreements of the Company set forth in this Subscription Agreement. Subscriber acknowledges that certain information provided by the Company 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. 
 (g)    In making its decision to purchase the Subscribed Shares,
Subscriber has relied solely upon independent investigation made by Subscriber and the Company’s representations warranties and covenants contained herein. Subscriber has not relied on any statements or other information provided by anyone
(including the Placement Agents) other than the Company concerning the Company, the Transaction, the Subscribed Shares or the offer and sale of the Subscribed Shares. Subscriber acknowledges and agrees that Subscriber has received and has had an
adequate opportunity to review such financial and other information as Subscriber deems necessary in order to make an investment decision with respect to the Subscribed Shares, including with respect to the Company and the Transaction (including
Micromidas and its subsidiaries (collectively, the “Acquired Companies”)) and made its own assessment and is satisfied concerning the relevant tax and other economic considerations relevant to Subscriber’s investment in the
Subscribed Shares. Subscriber represents and agrees that Subscriber and Subscriber’s professional advisor(s), if any, have had the full opportunity to ask such questions, receive such answers and obtain such information as Subscriber and such
undersigned’s professional advisor(s), if any, have deemed necessary to make an investment decision with respect to the Subscribed Shares. Without limiting the generality of the foregoing, Subscriber acknowledges that it has reviewed the
Company’s filings with the Commission. Subscriber acknowledges and agrees that neither the Placement Agents, nor any of the respective affiliates of the Placement Agents, have provided Subscriber with any information or advice with respect to
the Subscribed Shares nor is such information or advice necessary or desired. Neither the Placement Agents nor any of their respective affiliates have made or make any representation as to the Company or the Acquired Companies or the quality or
value of the Subscribed Shares and the Placement Agents and their respective affiliates may have acquired non-public information with respect to the Company or the Acquired Companies which Subscriber agrees,
subject to applicable law, need not be provided to it. Subscriber acknowledges that the Placement Agents and their respective directors, officers, employees, representatives and controlling persons have made no independent investigation with respect
to the Company, the Acquired Companies or the Shares or the accuracy, completeness or adequacy of any information supplied to Subscriber by the Company. In connection with the issuance of the Subscribed Shares to Subscriber, neither the Placement
Agents nor any of their respective affiliates have acted as a financial advisor or fiduciary to Subscriber. Subscriber acknowledges that no disclosure or offering document has been prepared by the Placement Agents in connection with the offer and
sale of the Shares. Subscriber agrees that the Placement Agents shall not be liable to any Subscriber for any action heretofore or hereafter taken or omitted to be taken by any of them in connection with Subscriber’s purchase of the Subscribed
Shares. 
 (h)    Subscriber became aware of this offering of the Subscribed Shares solely by means of direct contact
between Subscriber and the Company and/or Micromidas, or their respective representatives or affiliates, or by means of contact from one or more of the Placement Agents on behalf of the Company and the Subscribed Shares were offered to Subscriber
solely by direct contact between Subscriber and the Company and/or Micromidas, or their respective affiliates. Subscriber did not become aware of this offering of the Subscribed Shares, nor were the Subscribed Shares offered to Subscriber, by any
other means. Subscriber acknowledges that the Company represents and warrants that the Subscribed 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. 

(i)    Subscriber acknowledges that it is aware that there are substantial risks incident to the purchase and ownership of
the Subscribed Shares. Subscriber has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of an investment in the Subscribed Shares, and Subscriber has had an opportunity to seek, and
has sought, such accounting, legal, business and tax advice as Subscriber has considered necessary to make an informed investment decision. 

  
 7 

 (j)    Subscriber has adequately analyzed and fully considered the risks
of an investment in the Subscribed Shares and determined that the Subscribed Shares are a suitable investment for Subscriber and that Subscriber is able at this time and in the foreseeable future to bear the economic risk of a total loss of
Subscriber’s investment in the Company. Subscriber acknowledges specifically that a possibility of total loss exists. 

(k)    Subscriber understands and agrees that no federal or state agency has passed upon or endorsed the merits of the
offering of the Subscribed Shares or made any findings or determination as to the fairness of this investment. 

(l)    Subscriber is not owned or controlled by or acting on behalf of (in connection with this Transaction), a Sanctioned
Person. Subscriber is not an institution that accepts currency for deposit and that (a) has no physical presence in the jurisdiction in which it is incorporated or in which it is operating and (b) is unaffiliated with a regulated financial
group that is subject to consolidated supervision (a “Shell Bank”) or providing banking services to a Shell Bank. Subscriber represents that if it is a financial institution subject to the Bank Secrecy Act (31 U.S.C.
Section 5311 et seq.), as amended by the USA PATRIOT Act of 2001 and its implementing regulations (collectively, the “BSA/PATRIOT Act”), that Subscriber maintains policies and procedures reasonably designed to comply with
applicable obligations under the BSA/PATRIOT Act. Subscriber also represents that, to the extent required by applicable law, it maintains, either directly or through the use of a third-party administrator, policies and procedures reasonably designed
for the screening of any investors in Subscriber against Sanctions-related lists of blocked or restricted persons. Subscriber further represents and warrants that (a) the funds held by Subscriber and used to purchase the Subscribed Shares were
not directly or indirectly derived from or related to any activities that may contravene U.S. federal, state or non-U.S. anti-money laundering, anti-corruption or Sanctions laws and regulations or activities
that may otherwise be deemed criminal and (b) any returns from Subscriber’s investment will not be used to finance any illegal activities. For purposes of this Subscription Agreement, “Sanctioned Person” means at any time
any person or entity with whom dealings are restricted, prohibited, or sanctionable under any Sanctions (as defined below), including as a result of being: (a) listed on any Sanctions-related list of designated or blocked or restricted persons;
(b) that is a national of, the government of, or any agency or instrumentality of the government of, or resident in, or organized under the laws of, a country or territory that is the target of comprehensive Sanctions from time to time (as of
the date of this Subscription Agreement, Cuba, Iran, North Korea, Syria, and the Crimea region); or (c) a relationship of ownership, control, or agency with any of the foregoing. “Sanctions” means those trade, economic and
financial sanctions laws, regulations, embargoes, and restrictive measures (in each case having the force of law) administered, enacted or enforced from time to time by (a) the United States (including without limitation the U.S. Department of
the Treasury, Office of Foreign Assets Control, the U.S. Department of State, and the U.S. Department of Commerce), (b) the European Union and enforced by its member states, (c) the United Nations and (d) the United Kingdom. 

(m)    Subscriber is not owned or controlled by or acting on behalf of (in connection with this Transaction), a person or
entity resident in, or whose funds used to purchase the Subscribed Shares are transferred from or through, a country, territory or entity that (i) has been designated as non-cooperative with international
anti-money laundering or counter terrorist financing principles or procedures by the United States or by an intergovernmental group or organization, such as the Financial Action Task Force, of which the United States is a member; (ii) is the
subject of an advisory issued by the Financial Crimes Enforcement Network of the U.S. Department of the Treasury; or (iii) has been designated by the Secretary of the Treasury under Section 311 of the USA PATRIOT Act as warranting special
measures due to money laundering concerns (any such country or territory, a “Non-cooperative Jurisdiction”), or an entity or individual that resides or has a place of business in, or is organized
under the laws of, a Non-cooperative Jurisdiction. 
 (n)    Subscriber does not
have, as of the date hereof, and during the 30-day period immediately prior to the date hereof Subscriber has not entered into, any “put equivalent position” as such term is defined in Rule 16a-1 under the Exchange Act or Short Sale positions with respect to the securities of the Company. Notwithstanding the foregoing, in the case of a Subscriber that is a multi-managed investment vehicle whereby
separate portfolio managers manage separate portions of Subscriber’s assets and the portfolio managers have no direct knowledge of the investment decisions made by the portfolio managers managing other portions of Subscriber’s assets, the
representation set forth above shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the Subscribed Shares covered by this Subscription Agreement. 

  
 8 

 (o)    Subscriber is not currently (and at all times through Closing
will refrain from being or becoming) a member of a “group” (within the meaning of Section 13(d)(3) or Section 14(d)(2) of the Exchange Act or any successor provision) including any group acting for the purpose of acquiring,
holding, voting or disposing of equity securities of the Company (within the meaning of Rule 13d-5(b)(1) under the Exchange Act). 

(p)    If Subscriber is an employee benefit plan that is subject to Title I of the Employee Retirement Income Security Act
of 1974, as amended (“ERISA”), 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”) or 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 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, or an entity
whose underlying assets are considered to include “plan assets” of any such plan, account or arrangement (each, a “Plan”) subject to the fiduciary or prohibited transaction provisions of ERISA or section 4975 of the Code,
Subscriber represents and warrants that (i) neither the Company, nor any of its affiliates, including Artius Acquisition Partners, LLC (the “Transaction Parties”), has acted as the Plan’s fiduciary, or has been relied on
for advice, with respect to its decision to acquire and hold the Subscribed Shares, and none of the Transaction Parties shall at any time be relied upon as the Plan’s fiduciary with respect to any decision to acquire, continue to hold or
transfer the Subscribed Shares and (ii) the acquisition and holding of the Subscribed Shares will not result in a non-exempt prohibited transaction under ERISA or Section 4975 of the Code. 

(q)    Subscriber, at the time of payment of the Purchase Price in accordance with Section 2, will have sufficient
funds to pay the Purchase Price pursuant to Section 2. 
 (r)    Assuming the accuracy of the
representations and warranties of the Company in Section 3(l), except for the Placement Agents, no broker or finder is entitled to any brokerage or finder’s fee or commission solely in connection with the sale of the Subscribed Shares to
Subscriber. 
 (s)    Subscriber agrees that the Placement Agents may rely upon the representations and warranties made
by Subscriber to the Company in this Subscription Agreement. 
 Section 5    Registration of Subscribed
Shares. 
 (a)    The Company agrees that, within fifteen (15) Business Days after the Closing Date (the
“Filing Date”), the Company will file with the Commission (at the Company’s sole cost and expense) a registration statement registering the resale of the Subscribed Shares (the “Registration Statement”), and the
Company shall use its commercially reasonable efforts to have the Registration Statement declared effective as soon as practicable after the filing thereof (and in any event, no later than sixty (60) calendar days following the Filing Date)
(the “Effectiveness Deadline”), provided, that the Effectiveness Deadline shall be extended to ninety (90) calendar days after the Filing Date if the Registration Statement is reviewed by, and comments thereto are provided
from, the Commission; provided, that if such day falls on a Saturday, Sunday or other day that the Commission is closed for business, the Effectiveness Deadline shall be extended to the next Business Day on which the Commission is open for business.
Notwithstanding the foregoing, if the Company is notified (orally or in writing, whichever is earlier) by the Commission that the Registration Statement will not be “reviewed” or subject to further review, the Company shall use its
commercially reasonable efforts to have the Registration Statement declared effective within ten (10) Business Days of receipt of such notice. The Company will use its commercially reasonable efforts to provide a draft of the Registration
Statement to the undersigned for review (but not comment, other than reasonable comments with respect to information being provided by Subscriber for inclusion in the Registration Statement) at least two (2) Business Days in advance of filing
the Registration Statement; provided that, for the avoidance of doubt, in no event shall the Company be required to delay or postpone the filing of such Registration Statement as a result of or in connection with Subscriber’s review.
Notwithstanding the foregoing, if the Commission prevents the Company 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 Subscribed Shares by the applicable stockholders or otherwise, such Registration Statement shall register for resale such number of Subscribed Shares which is equal to 

  
 9 

 
the maximum number of Subscribed Shares as is permitted by the Commission. In such event, the number of Subscribed Shares to be registered for each selling stockholder named in the Registration
Statement shall be reduced pro rata among all such selling stockholders. The Company agrees that, except for such times as the Company is permitted hereunder to suspend the use of the prospectus forming part of a Registration Statement, the
Company will use commercially reasonable efforts to cause such Registration Statement to remain effective with respect to Subscriber until the earlier of (i) two (2) years from the issuance of the Subscribed Shares, (ii) the date on which
all of the Subscribed Shares shall have been sold, or (iii) on the first date on which the undersigned can sell all of its Subscribed Shares (or shares received in exchange therefor) under Rule 144 of the Securities Act without limitation as to
the manner of sale or the amount of such securities that may be sold. For as long as the Company is required to use commercially reasonable efforts to cause the Registration Statement to remain effective pursuant to the immediately preceding
sentence, the Company will use commercially reasonable efforts to file all reports, and provide all customary and reasonable cooperation, necessary to enable the undersigned to resell the Subscribed Shares pursuant to the Registration Statement or
Rule 144 of the Securities Act (when Rule 144 of the Securities Act becomes available to the Company), as applicable, qualify the Subscribed Shares for listing on the applicable stock exchange on which the Company’s Shares are then listed, and
update or amend the Registration Statement as necessary to include the Subscribed Shares. The undersigned agrees to disclose its beneficial ownership, as determined in accordance with Rule 13d-3 of the
Exchange Act, of Subscribed Shares to the Company (or its successor) upon request to assist the Company in making the determination described above. The Company’s obligations to include the Subscribed Shares in the Registration Statement are
contingent upon Subscriber furnishing in writing to the Company such information regarding Subscriber, the securities of the Company held by Subscriber and the intended method of disposition of the Subscribed Shares as shall be reasonably requested
by the Company to effect the registration of the Subscribed Shares, and Subscriber shall execute such documents in connection with such registration as the Company may reasonably request that are customary of a selling stockholder in similar
situations, including providing that the Company shall be entitled to postpone and suspend the effectiveness or use of the Registration Statement during any customary blackout or similar period or as permitted hereunder; provided, that Subscriber
shall not in connection with the foregoing be required to execute any lock-up or similar agreement or otherwise be subject to any contractual restriction on the ability to transfer the Subscribed Shares. In the case of the registration effected by
the Company pursuant to this Subscription Agreement, the Company shall, upon reasonable request, inform Subscriber as to the status of such registration. In no event shall Subscriber be identified as a statutory underwriter in the Registration
Statement unless requested by the Commission. If the Commission requests that Subscriber be identified as a statutory underwriter in the Registration Statement, Subscriber shall have an opportunity to withdraw from the Registration Statement.
Subscriber shall not be entitled to use the Registration Statement for an underwritten offering of Subscribed Shares. Notwithstanding anything to the contrary contained herein, the Company may delay or postpone filing of such Registration Statement,
and from time to time require Subscriber not to sell under the Registration Statement or suspend the use or effectiveness of any such Registration Statement if it determines that in order for the registration statement to not contain a material
misstatement or omission, an amendment thereto would be needed, or if such filing or use could materially affect a bona fide business or financing transaction of the Company or would require premature disclosure of information that could materially
adversely affect the Company (each such circumstance, a “Suspension Event”); provided, that, (w) the Company shall not so delay filing or so suspend the use of the Registration Statement for a period of more than ninety
(90) consecutive days or more than a total of one hundred- twenty (120) calendar days, in each case in any three hundred sixty (360) day period and (x) the Company shall use commercially reasonable efforts to make such
registration statement available for the sale by the undersigned of such securities as soon as practicable thereafter. 

(b)    At its expense, the Company shall advise Subscriber within two (2) Business Days: (i) of the issuance by the
Commission of any stop order suspending the effectiveness of any Registration Statement or the initiation of any proceedings for such purpose; (ii) of the receipt by the Company of any notification with respect to the suspension of the qualification
of the Subscribed Shares included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and (iii) subject to the provisions in this Subscription Agreement, of the occurrence of a Suspension Event.
Notwithstanding anything to the contrary set forth herein, the Company shall not, when so advising Subscriber of such events, provide Subscriber with any material, non-public information regarding the Company other than to the extent that providing
notice to Subscriber of the occurrence of such events would constitute material, non-public information regarding the Company. 

(c)    Upon receipt of any written notice from the Company (which notice shall not contain any material non-public information regarding the Company) 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 undersigned agrees that (i) it will immediately discontinue offers and sales of the Subscribed Shares under the Registration Statement (excluding, for the avoidance of doubt, sales conducted
pursuant to Rule 144) until the undersigned receives copies of a supplemental or amended prospectus (which the Company agrees to promptly prepare) that corrects the misstatement(s) or omission(s) referred to above and receives notice that any
post-effective amendment has become effective or unless otherwise notified by the Company that it may resume such offers and sales, and (ii) it will maintain the confidentiality of any information included in such written notice delivered by
the Company unless otherwise required by law, subpoena or regulatory request or 

  
 10 

 
requirement. If so directed by the Company, the undersigned will deliver to the Company or, in the undersigned’s sole discretion destroy, all copies of the prospectus covering the Subscribed
Shares in the undersigned’s possession; provided, however, that this obligation to deliver or destroy all copies of the prospectus covering the Subscribed Shares shall not apply (w) to the extent the undersigned is required to retain a
copy of such prospectus (A) in order to comply with applicable legal, regulatory, self-regulatory or professional requirements or (B) in accordance with a bona fide pre-existing document retention
policy or (x) to copies stored electronically on archival servers as a result of automatic data back-up. 

(d) For purposes of this Section 5, “Subscribed Shares” shall mean, as of any date of determination, the Subscribed Shares (as
defined in the recitals to this Subscription Agreement) and any other equity security issued or issuable with respect to the Subscribed Shares by way of share split, dividend, distribution, recapitalization, merger, exchange, replacement or similar
event, and “Subscriber” shall include any affiliate of the undersigned Subscriber to which the rights under this Section 5 shall have been duly assigned. 

(e)     
  

	 	(i)	 The Company agrees to indemnify, to the extent permitted by law, Subscriber (to the extent a seller under the
Registration Statement), its directors and officers, employees and agents, and each person who controls Subscriber (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 (plus the fees of any local counsel)) caused by any untrue or alleged untrue statement of material fact contained in, or
incorporated by reference in, the Registration Statement, prospectus included in the 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 furnished in writing to the Company by or on behalf of Subscriber expressly for use therein. 

  

	 	(ii)	 Subscriber shall, to the extent permitted by law, indemnify the Company, its directors and officers, employees
and agents, and each person or entity who controls the Company (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 in, or incorporated by reference in, the 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 or on behalf of Subscriber expressly for use therein. In no event shall the
liability of Subscriber be greater in amount than the dollar amount of the net proceeds received by Subscriber upon the sale of the Subscribed Shares giving rise to such indemnification obligation. Subscriber shall notify the Company promptly of the
institution, threat or assertion of any proceeding arising from or in connection with the transactions contemplated by this Section 5 of which Subscriber is aware. 

 

	 	(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 or separate defenses 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, delayed or conditioned). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees
and expenses of more than one counsel (plus any local counsel) for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of legal counsel to any indemnified party a conflict of interest
exists between such indemnified party and any other of such 

  
 11 

	 	
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 the Subscribed Shares purchased pursuant to this
Subscription Agreement. 

  

	 	(v)	 If the indemnification provided under this Section 5(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. 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),
or on behalf of, 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 5(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 5(e)(v) from any person or entity who was not guilty of such fraudulent misrepresentation. Notwithstanding anything to the contrary herein, in no event will any party be liable for
consequential, special, exemplary or punitive damages in connection with this Subscription Agreement. Each indemnifying party’s obligation to make a contribution pursuant to this Section 5(e)(v) shall be individual, not joint and several, and
in no event shall the liability of any Subscriber hereunder be greater in amount than the dollar amount of the net proceeds received by such Subscriber upon the sale of the Subscribed Shares giving rise to such indemnification obligation.

 (f)    If the Subscribed Shares acquired hereunder are eligible to be sold without restriction
under, and without the requirement for the Company to be in compliance with the current public information requirements of, Rule 144 then at Subscriber’s request, the Company will reasonably cooperate with the Company’s transfer agent,
such that any remaining restrictive legend set forth on such Subscribed Shares will be removed in connection with a sale of such shares. 

Section 6    Short Sales. Subscriber hereby agrees that, from the date of this Subscription Agreement until
the earlier of the Closing or the termination of this Subscription Agreement, none of Subscriber, its controlled affiliates, or any person or entity acting on behalf of Subscriber or any of its controlled affiliates or pursuant to any understanding
with Subscriber or any of its controlled affiliates will engage in any Short Sales with respect to securities of the Company prior to the Closing. For purposes of this Subscription Agreement, “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 Subscriber that have no knowledge of this Subscription Agreement or of Subscriber’s participation in
the Transaction (including Subscriber’s controlled affiliates and/or affiliates) from entering into any Short Sales 

  
 12 

 
and (ii) in the case of a Subscriber that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Subscriber’s assets and the
portfolio managers have no knowledge of the investment decisions made by the portfolio managers managing other portions of such Subscriber’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 Subscribed Shares covered by this Subscription Agreement. 

Section 7    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 either party in respect thereof, upon the earlier 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 the parties hereto to terminate this Subscription Agreement, or (c) if, on the Closing Date of the Transaction, any of the conditions to Closing set forth in
Section 2 of this Subscription Agreement have not been satisfied as of the time required hereunder to be so satisfied or waived by the party entitled to grant such waiver and, as a result thereof, the transactions contemplated by this
Subscription Agreement are not consummated, or (d) written notice by either party to the other party to terminate this Subscription Agreement if the transactions contemplated by this Subscription Agreement are not consummated on or prior to
August 31, 2021; provided, that nothing herein will relieve any party from liability for any intentional breach hereof prior to the time of termination, and each party will be entitled to any remedies at law or in equity to recover losses,
liabilities or damages arising from such breach. The Company shall notify Subscriber of the termination of the Transaction Agreement promptly after the termination thereof. 

Section 8    Trust Account Waiver. Subscriber hereby acknowledges that the Company has established a trust
account (the “Trust Account”) containing the proceeds of its initial public offering (the “IPO”) and from certain private placements occurring simultaneously with the IPO (including interest accrued from time to
time thereon) for the benefit of the Company’s public stockholders and certain other parties (including the underwriters of the IPO). For and in consideration of the Company entering into this Subscription Agreement, and for other good and
valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Subscriber hereby (a) agrees that it does not now and shall not at any time hereafter have any right, title, interest or claim of any kind in or to any assets
held in the Trust Account, and shall not make any claim against the Trust Account, regardless of whether such claim arises as a result of, in connection with or relating in any way to this Subscription Agreement or any other matter, and regardless
of whether such claim arises based on contract, tort, equity or any other theory of legal liability (any and all such claims are collectively referred to hereafter as the “Released Claims”), (b) irrevocably waives any Released
Claims that it may have against the Trust Account now or in the future as a result of, or arising out of, any negotiations, contracts or agreements with the Company, and (c) will not seek recourse against the Trust Account for any reason
whatsoever; provided, however, that nothing in this Section 8 shall be deemed to limit any Subscriber’s right to distributions from the Trust Account in accordance with the Company’s amended and restated
certificate of incorporation in respect of the Shares of the Company acquired by any means other than pursuant to this Subscription Agreement. 

Section 9    Miscellaneous. 

(a)    All notices, requests, demands, claims, and other communications hereunder shall be in writing. Any notice,
request, demand, claim, or other communication hereunder shall be deemed duly given (i) when delivered personally to the recipient, (ii) when sent by electronic mail (which is confirmed), on the date of transmission to such recipient;
(iii) one (1) Business Day after being sent to the recipient by reputable overnight courier service (charges prepaid), or (iv) four (4) Business Days after being mailed to the recipient by certified or registered mail, return receipt
requested and postage prepaid, and, in each case, addressed to the intended recipient at its address specified on the signature page hereof or to such electronic mail address or address as subsequently modified by written notice given in accordance
with this Section 9(a). A courtesy electronic copy of any notice sent by methods (i), (iii), or (iv) above shall also be sent to the recipient via electronic mail if provided in the applicable signature page hereof or
to an electronic mail address as subsequently modified by written notice given in accordance with this Section 9(a). 

(b)    Subscriber acknowledges that the Company, Micromidas, the Placement Agents and others will rely on the
acknowledgments, understandings, agreements, representations and warranties of Subscriber contained in this Subscription Agreement. Prior to the Closing, Subscriber agrees to promptly notify the Company, Micromidas and each of the Placement Agents
if it becomes aware that any of the acknowledgments, understandings, agreements, 

  
 13 

 
representations and warranties of Subscriber set forth herein are no longer accurate in all material respects. The Company acknowledges that Subscriber and the Placement Agents will rely on the
acknowledgments, understandings, agreements, representations and warranties contained in this Subscription Agreement. Prior to the Closing, the Company agrees to promptly notify Subscriber and each of the Placement Agents if it becomes aware that
any of the acknowledgments, understandings, agreements, representations and warranties of the Company set forth herein are no longer accurate in all material respects. 

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

(d)    Each of the Company and Subscriber shall pay all of its own expenses in connection with this Subscription Agreement
and the transactions contemplated herein. The Company shall be responsible for the fees of its transfer agent, stamp taxes and DTC fees associated with the issuance of the Subscribed Shares. 

(e)    Neither this Subscription Agreement nor any rights that may accrue to Subscriber hereunder (other than the
Subscribed Shares acquired hereunder, if any) may be transferred or assigned. Neither this Subscription Agreement nor any rights that may accrue to the Company hereunder may be transferred or assigned (provided, that, for the avoidance of doubt, the
Company may transfer the Subscription Agreement and its rights hereunder solely in connection with the consummation of the Transaction and exclusively to another entity under the control of, or under common control with, the Company).
Notwithstanding the foregoing, Subscriber may assign its rights and obligations under this Subscription Agreement to one or more of its affiliates (including other investment funds or accounts managed or advised by the investment manager who acts on
behalf of Subscriber or by an affiliate of such investment manager) or, with the Company’s prior written consent, to another person, provided that no such assignment shall relieve Subscriber of its obligations hereunder if any such assignee
fails to perform such obligations, unless the Company has given prior written consent to such relief. 
 (f)    All the
agreements, representations and warranties made by each party hereto in this Subscription Agreement shall survive the Closing. 

(g)    The Company may request from Subscriber such additional information as the Company may reasonably deem necessary to
evaluate the eligibility of Subscriber to acquire the Subscribed Shares, and Subscriber shall promptly provide such information as may be reasonably requested. Subscriber acknowledges that the Company may file a copy of a form of this Subscription
Agreement with the Commission (and such copy shall not identify Subscriber and, if applicable, its investment adviser by name (except to the extent required by the federal securities laws, exchange rules, the Commission or any other securities
authorities or any rules and regulations promulgated thereby)) as an exhibit to a periodic report of the Company or a registration statement of the Company. 

(h)    This Subscription Agreement may not be amended, modified or waived except by an instrument in writing signed by
each of the parties hereto. 
 (i)    This Subscription Agreement and any
non-disclosure agreement entered into by the parties hereto constitute 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. 
 (j)    Except as otherwise provided herein, this
Subscription Agreement is intended for the benefit of the parties hereto and their heirs, executors, administrators, successors, legal representatives, and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by,
any other person. Except as set forth in Section 9(b), Section 9(c) and this Section 9(j) with respect to the persons specifically 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, and the parties hereto acknowledge that such persons so referenced are third party beneficiaries of this
Subscription Agreement for the purposes of, and to the extent of, the rights granted to them, if any, pursuant to the applicable provisions. 

  
 14 

 (k)    The parties hereto acknowledge and agree that (i) this
Subscription Agreement is being entered into in order to induce the Company to execute and deliver the Transaction Agreement and (ii) 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 and that money or other legal remedies would not be an adequate remedy for such damage. It is accordingly agreed that the parties shall be entitled to equitable relief,
including in the form of an injunction or injunctions to prevent breaches or threatened breaches of this Subscription Agreement and to enforce specifically the terms and provisions of this Subscription Agreement, this being in addition to any other
remedy to which such party is entitled at law, in equity, in contract, in tort or otherwise. The parties hereto acknowledge and agree that Micromidas and the Placement Agents shall be entitled to rely on the provisions of the Subscription Agreement
of which Micromidas and the Placement Agents are each an express third party beneficiary, in each case, on the terms and subject to the conditions set forth herein. The parties hereto further acknowledge and agree: (x) to waive any requirement
for the security or posting of any bond in connection with any such equitable remedy; (y) not to assert that a remedy of specific enforcement pursuant to this Section 9(j) is unenforceable, invalid, contrary to
applicable law or inequitable for any reason; and (z) to waive any defenses in any action for specific performance, including the defense that a remedy at law would be adequate. 

(l)    In any dispute arising out of or related to this Subscription Agreement, or any other agreement, document,
instrument or certificate contemplated hereby, or any transactions contemplated hereby or thereby, the applicable adjudicating body shall award to the prevailing party, if any, the documented out-of-pocket costs and attorneys’ fees reasonably incurred by the prevailing party in connection with the dispute and the enforcement of its rights under this Subscription Agreement or any other
agreement, document, instrument or certificate contemplated hereby and, if the adjudicating body determines a party to be the prevailing party under circumstances where the prevailing party won on some but not all of the claims and counterclaims,
the adjudicating body may award the prevailing party an appropriate percentage of the documented out-of-pocket costs and attorneys’ fees reasonably incurred by the
prevailing party in connection with the adjudication and the enforcement of its rights under this Subscription Agreement or any other agreement, document, instrument or certificate contemplated hereby or thereby. 

(m)    If any provision of this Subscription Agreement shall be invalid, illegal or unenforceable, the validity, legality
or enforceability of the remaining provisions of this Subscription Agreement shall not in any way be affected or impaired thereby and shall continue in full force and effect. 

(n)    No failure or delay by a party hereto in exercising any right, power or remedy under this Subscription Agreement,
and no course of dealing between the parties hereto, shall operate as a waiver of any such right, power or remedy of such party. No single or partial exercise of any right, power or remedy under this Subscription Agreement by a party hereto, nor any
abandonment or discontinuance of steps to enforce any such right, power or remedy, shall preclude such party from any other or further exercise thereof or the exercise of any other right, power or remedy hereunder. The election of any remedy by a
party hereto shall not constitute a waiver of the right of such party to pursue other available remedies. No notice to or demand on a party not expressly required under this Subscription Agreement shall entitle the party receiving such notice or
demand to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the party giving such notice or demand to any other or further action in any circumstances without such notice or demand. 

(o)    This Subscription Agreement may be executed and delivered in one or more counterparts (including by facsimile or
electronic mail or in .pdf) and by different parties in separate counterparts, with the same effect as if all parties hereto had signed the same document. All counterparts so executed and delivered shall be construed together and shall constitute
one and the same agreement. 
 (p)    This Subscription Agreement shall be governed by, and construed in accordance
with, the laws of the State of New York, without regard to the principles of conflicts of laws that would otherwise require the application of the law of any other state. 

(q)    EACH PARTY AND ANY PERSON ASSERTING RIGHTS AS A THIRD PARTY BENEFICIARY HEREBY WAIVES ITS RESPECTIVE RIGHTS TO A
TRIAL BY JURY OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OR RELATED TO THIS SUBSCRIPTION AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY IN ANY ACTION,  

  
 15 

 
PROCEEDING OR OTHER LITIGATION OF ANY TYPE BROUGHT BY ANY PARTY AGAINST ANY OTHER PARTY OR ANY AFFILIATE OF ANY OTHER SUCH PARTY, WHETHER WITH RESPECT TO CONTRACT CLAIMS, TORT CLAIMS OR
OTHERWISE. THE PARTIES AGREE THAT ANY SUCH CLAIM OR CAUSE OF ACTION SHALL BE TRIED BY A COURT TRIAL WITHOUT A JURY. WITHOUT LIMITING THE FOREGOING, THE PARTIES FURTHER AGREE THAT THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY IS WAIVED BY OPERATION OF
THIS SECTION AS TO ANY ACTION, COUNTERCLAIM OR OTHER PROCEEDING WHICH SEEKS, IN WHOLE OR IN PART, TO CHALLENGE THE VALIDITY OR ENFORCEABILITY OF THIS SUBSCRIPTION AGREEMENT OR ANY PROVISION HEREOF. THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT
AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS SUBSCRIPTION AGREEMENT. 
 (r)    The parties agree that
all disputes, legal actions, suits and proceedings arising out of or relating to this Subscription Agreement must be brought exclusively in the United States District Court for the Southern District of New York, the Supreme Court of the State of New
York and the federal or state appellate courts located in the State of New York (collectively the “Designated Courts”). Each party hereby consents and submits to the exclusive jurisdiction of the Designated Courts. No legal action,
suit or proceeding with respect to this Subscription Agreement may be brought in any other forum. Each party hereby irrevocably waives all claims of immunity from jurisdiction, and any objection which such party may now or hereafter have to the
laying of venue of any suit, action or proceeding in any Designated Court, including any right to object on the basis that any dispute, action, suit or proceeding brought in the Designated Courts has been brought in an improper or inconvenient forum
or venue. Each of the parties also agrees that delivery of any process, summons, notice or document to a party hereof in compliance with Section 9(a) of this Subscription Agreement shall be effective service of process for
any action, suit or proceeding in a Designated Court with respect to any matters to which the parties have submitted to jurisdiction as set forth above. 

(s)    This Subscription Agreement may only be enforced against, and any claim, action, suit or other legal proceeding
based upon, arising out of, or related to this Subscription Agreement, or the negotiation, execution or performance of this Subscription Agreement, may only be brought against the entities that are expressly named as parties or third party
beneficiaries hereto and then only with respect to the specific obligations set forth herein with respect to such party or third party beneficiary. No past, present or future director, officer, employee, incorporator, manager, member, partner,
stockholder, affiliate, agent, attorney or other representative of any party hereto or of any affiliate of any party hereto, or any of their successors or permitted assigns, shall have any liability for any obligations or liabilities of any party
hereto under this Subscription Agreement or for any claim, action, suit or other legal proceeding based on, in respect of or by reason of the transactions contemplated hereby. 

(t)    Notwithstanding anything in this Subscription Agreement to the contrary, the Company shall not publicly disclose
the name of Subscriber, its investment adviser or any of their respective affiliates, Subscriber’s beneficial ownership of the Subscribed Shares, or the nature of Subscriber’s commitments, arrangements and understandings under and relating
to this Subscription Agreement in any press release issued by the Company, any Form 8-K filed by the Company with the Commission in connection with the execution and delivery of the Transaction Agreement or
the transactions contemplated thereby and the Registration Statement (as defined in the Transaction Agreement), except to the extent required by the federal securities laws, exchange rules, the Commission or any other securities authorities or any
rules and regulations promulgated thereby or with Subscriber’s consent; provided, however, that the Company shall provide Subscriber with prior written notice of any such disclosure required by the federal securities laws, exchange rules, the
Commission or any other securities authorities or any rules and regulations promulgated thereby and shall reasonably consult with Subscriber regarding such disclosure. Subscriber will promptly provide any information reasonably requested by the
Company for any regulatory application or filing made or approval sought in connection with the Transaction (including filings with the Commission). The Company has disclosed to Subscriber certain non-public information regarding the Transaction,
including the material terms of the transactions contemplated hereby (and by the Other Subscription Agreements), and Subscriber acknowledges its agreement to treat such information confidentially until such time as all such “material non-public
information” (within the meaning of applicable securities laws) is either publicly disclosed by the Company or deemed by the Company to be no longer relevant. In accordance therewith, the Company shall, by 9:30 a.m., New York City time, on the
first (1st) Business Day immediately following the date of this Subscription Agreement, issue one or more press releases or file with the Commission a Current Report on Form 8-K disclosing, to the extent not previously publicly disclosed, such
material non-public information unless the Company determines, in compliance with applicable laws and regulations, that any of such information is no longer material. 

(u)    If any change in the Shares shall occur between the date of this Subscription Agreement and immediately prior to
the Closing by reason of any reclassification, recapitalization, stock split (including reverse stock split) or combination, exchange or readjustment of shares, or any stock dividend, the number of Subscribed Shares issued to Subscriber shall be
appropriately adjusted to reflect such change. 

  
 16 

 (v)    The obligations of Subscriber under this Subscription Agreement
are several and not joint with the obligations of any Other Subscriber or any other investor under the Other Subscription Agreements, and Subscriber shall not be responsible in any way for the performance of the obligations of any Other Subscriber
under this Subscription Agreement or any Other Subscriber or other investor under the Other Subscription Agreements. The decision of Subscriber to purchase Subscribed Shares pursuant to this Subscription Agreement has been made by Subscriber
