Attn: Paul Shim 
 RE: Securities Subscription
Agreement 
 Ladies and Gentlemen: 
 This
agreement (this “Agreement”) is entered into on February 4, 2020, by and between Artius Acquisition Partners LLC, a Delaware limited liability company (the “Subscriber” or “you”), and Artius
Acquisition Inc., a Cayman Islands exempted company (the “Company”, “we” or “us”). Pursuant to the terms hereof, the Company hereby accepts the offer the Subscriber has made to subscribe for and
purchase 11,500,000 Class B ordinary shares (the “Shares”), $0.0001 par value per share (the “Class B Ordinary Shares” together with all other classes of Company common shares, the
“Ordinary Shares”), up to 1,500,000 of which are subject to forfeiture by you if the underwriters of the initial public offering (“IPO”) of units (“Units”) of the Company, if any, do not
fully exercise their over-allotment option (the “Over-allotment Option”). The Company’s and the Subscriber’s agreements regarding such Shares are as follows: 

1. Subscription for Shares. 
 For the sum
of $25,000 (the “Purchase Price”), which the Subscriber or an affiliate of the Subscriber shall have paid on behalf of the Company to cover Company expenses, the Company hereby issues and sells the Shares to the Subscriber, and the
Subscriber hereby subscribes for and purchases the Shares from the Company, subject to forfeiture, on the terms and subject to the conditions set forth in this Agreement. All references in this Agreement to shares of the Company being forfeited
shall take effect as surrenders for no consideration of such shares as a matter of Cayman Islands law. 
 The Subscriber hereby irrevocably
surrenders to the Company for cancellation and for nil consideration the one Class B ordinary share standing in its name in the register of members of the Company. 

2. Representations, Warranties and Agreements. 

2.1 The Subscriber’s Representations, Warranties and Agreements. To induce the Company to issue the Shares to the Subscriber, the
Subscriber hereby represents and warrants to the Company and agrees with the Company as follows: 












 2.1.1 No Government Recommendation or Approval. The Subscriber understands that no
federal or state agency has passed upon or made any recommendation or endorsement of the offering of the Shares. 
 2.1.2 No
Conflicts. The execution, delivery and performance of this Agreement and the consummation by the Subscriber of the transactions contemplated hereby do not violate, conflict with or constitute a default under (i) the formation and governing
documents of the Subscriber, (ii) any agreement, indenture or instrument to which the Subscriber is a party or (iii) any law, statute, rule or regulation to which the Subscriber is subject, or any agreement, order, judgment or decree to
which the Subscriber is subject. 
 2.1.3 Organization and Authority. The Subscriber is a Delaware limited liability company, validly
existing and in good standing under the laws of Delaware, and possesses all requisite power and authority necessary to carry out the transactions contemplated by this Agreement. Upon execution and delivery by you, this Agreement is a legal, valid
and binding agreement of the Subscriber, enforceable against the Subscriber in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, fraudulent conveyance or similar laws affecting the
enforcement of creditors’ rights generally and subject to general principles of equity (regardless of whether enforcement is sought in a proceeding at law or in equity). 

2.1.4 Experience, Financial Capability and Suitability. The Subscriber is: (i) sophisticated in financial matters and is able to
evaluate the risks and benefits of the investment in the Shares and (ii) able to bear the economic risk of its investment in the Shares for an indefinite period of time because the Shares have not been registered under the Securities Act of
1933, as amended (the “Securities Act”), and therefore cannot be sold unless subsequently registered under the Securities Act or an exemption from such registration is available. The Subscriber is capable of evaluating the merits
and risks of its investment in the Company and has the capacity to protect its own interests. The Subscriber must bear the economic risk of this investment until the Shares are sold pursuant to: (i) an effective registration statement under the
Securities Act or (ii) an exemption from registration available with respect to such sale. The Subscriber is able to bear the economic risks of an investment in the Shares and to afford a complete loss of the Subscriber’s investment in the
Shares. 
 2.1.5 Access to Information; Independent Investigation. Prior to the execution of this Agreement, the Subscriber has had
the opportunity to ask questions of and receive answers from representatives of the Company concerning an investment in the Company, as well as the finances, operations, business and prospects of the Company, and the opportunity to obtain additional
information to verify the accuracy of all information so obtained. In determining whether to make this investment, the Subscriber has relied solely on the Subscriber’s own knowledge and understanding of the Company and its business based upon
the Subscriber’s own due diligence investigation and the information furnished pursuant to this paragraph. The Subscriber understands that no person has been authorized to give any information or to make any representations which were not
furnished pursuant to this Section 2 and the Subscriber has not relied on any other representations or information in making its investment decision, whether written or oral, relating to the Company, its operations and/or its prospects.

 2.1.6 Regulation D Offering. The Subscriber represents that it is an “accredited
investor” as such term is defined in Rule 501(a) of Regulation D under the Securities Act and acknowledges the sale contemplated hereby is being made in reliance on a private placement exemption applicable to “accredited investors”
within the meaning of Section 501(a) of Regulation D under the Securities Act or similar exemptions under state law. 
 2.1.7
Investment Purposes. The Subscriber is purchasing the Shares solely for investment purposes, for the Subscriber’s own account and not for the account or benefit of any other person, and not with a view towards the distribution or
dissemination thereof in violation of the registration requirements of the Securities Act. The Subscriber did not decide to enter into this Agreement as a result of any general solicitation or general advertising within the meaning of Rule 502 under
the Securities Act. 
 2.1.8 Restrictions on Transfer; Shell Company. The Subscriber understands the Shares are being offered in a
transaction not involving a public offering within the meaning of the Securities Act. The Subscriber understands the Shares will be “restricted securities” within the meaning of Rule l44(a)(3) under the Securities Act, and the Subscriber
understands that the certificates representing the Shares will contain a legend in respect of such restrictions. If in the future the Subscriber decides to offer, resell, pledge or otherwise transfer the Shares, such Shares may be offered, resold,
pledged or otherwise transferred only pursuant to: (i) registration under the Securities Act or (ii) an available exemption from registration. The Subscriber agrees that if any transfer of its Shares or any interest therein is proposed to
be made, as a condition precedent to any such transfer, the Subscriber may be required to deliver to the Company an opinion of counsel satisfactory to the Company as described in Section 5.1 below. Absent registration or an exemption, the
Subscriber agrees not to resell the Shares. The Subscriber further acknowledges that because the Company is a shell company, Rule 144 may not be available to the Subscriber for the resale of the Shares until at least one year following consummation
of the initial business combination of the Company, despite technical compliance with the requirements of Rule 144 and the release or waiver of any contractual transfer restrictions. 

2.1.9 No Governmental Consents. No governmental, administrative or other third party consents or approvals are required, necessary or
appropriate on the part of the Subscriber in connection with the transactions contemplated by this Agreement. 
 2.2 The Company’s
Representations, Warranties and Agreements. To induce the Subscriber to subscribe for and purchase the Shares, the Company hereby represents and warrants to the Subscriber and agrees with the Subscriber as follows: 

2.2.1 Organization and Power. The Company is a Cayman Islands exempted company and is qualified to do business in every jurisdiction in
which the failure to so qualify would reasonably be expected to have a material adverse effect on the financial condition, operating results or assets of the Company. The Company possesses all requisite power and authority necessary to carry out the
transactions contemplated by this Agreement. 
 2.2.2 No Conflicts. The execution, delivery and performance of this Agreement and the
consummation by the Company of the transactions contemplated hereby do not violate, conflict with or constitute a default under (i) the memorandum and articles of association of the 

  
 3 













 
Company, (ii) any agreement, indenture or instrument to which the Company is a party or (iii) any law, statute, rule or regulation to which the Company is subject, or any agreement,
order, judgment or decree to which the Company is subject. 
 2.2.3 Title to Securities. Upon issuance in accordance with, and
payment pursuant to, the terms hereof, and registration in the Company’s register of members, the Shares will be duly and validly issued, fully paid and non-assessable. Upon issuance in accordance with,
and payment pursuant to, the terms hereof, and registration in the Company’s register of members, the Subscriber will have or receive good title to the Shares, free and clear of all liens, claims and encumbrances of any kind, other than
(i) transfer restrictions hereunder and under other agreements to which the Shares may be subject, (ii) transfer restrictions under federal and state securities laws, and (iii) liens, claims or encumbrances imposed due to the actions
of the Subscriber. 
 2.2.4 No Adverse Actions. There are no actions, suits, investigations or proceedings pending, threatened
against or affecting the Company which: (i) seek to restrain, enjoin, prevent the consummation of or otherwise affect the transactions contemplated by this Agreement or (ii) question the validity or legality of any transactions or seek to
recover damages or to obtain other relief in connection with any transactions. 
 3. Forfeiture of Shares. 

3.1 Partial or No Exercise of the Over-allotment Option. In the event the Over-allotment Option granted to the underwriters of the IPO
is not exercised in full, the Subscriber acknowledges and agrees that it shall forfeit any and all rights to such number of Shares (up to an aggregate of 1,500,000 Shares and pro rata based upon the percentage of the Over-allotment Option exercised)
such that immediately following such forfeiture, the number of Class B Ordinary Shares will equal 20% of the issued and outstanding Ordinary Shares immediately following the IPO. 

3.2 Termination of Rights as Shareholder. If any of the Shares are forfeited in accordance with this Section 3, then after such
time the Subscriber (or successor in interest) shall no longer have any rights as a holder of such forfeited Shares, and the Company shall take such action as is appropriate to cancel such Shares. 

4. Waiver of Liquidation Distributions; Redemption Rights. In connection with the Shares subscribed for and purchased pursuant to this Agreement, the
Subscriber hereby waives any and all right, title, interest or claim of any kind in, or to any distributions by the Company from, the trust account which will be established for the benefit of the Company’s public shareholders and into which
substantially all of the proceeds of the IPO will be deposited (the “Trust Account”), in the event of a liquidation of the Company upon the Company’s failure to timely complete an initial business combination. For purposes of
clarity, in the event the Subscriber purchases securities in the IPO or in the aftermarket, any Class A Shares so purchased shall be eligible to receive any liquidating distributions by the Company. However, in no event will the Subscriber have
the right to redeem any Ordinary Shares for funds held in the Trust Account upon the successful completion of an initial business combination.

 5. Restrictions on Transfer. 

5.1 Restrictive Legends. Any certificates representing the Shares shall have endorsed thereon legends substantially as follows: 

“THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE
SECURITIES LAWS AND NEITHER THE SECURITIES NOR ANY INTEREST THEREIN MAY BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT OR SUCH LAWS OR AN EXEMPTION FROM
REGISTRATION UNDER SUCH ACT AND SUCH LAWS WHICH, IN THE OPINION OF COUNSEL (WHICH THE COMPANY MAY WAIVE), IS AVAILABLE.” 

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO ADDITIONAL RESTRICTIONS ON TRANSFER SET FORTH IN THE LETTER AGREEMENT
BY AND BETWEEN THE COMPANY AND THE SPONSOR.” 
 5.2 Additional Shares or Substituted Securities. In the event of the
declaration of a share dividend, the declaration of an extraordinary dividend payable in a form other than Ordinary Shares, a spin-off, a share split, an adjustment in conversion ratio, a recapitalization or a
similar transaction affecting the outstanding Ordinary Shares without receipt of consideration, any new, substituted or additional securities or other property which are by reason of such transaction distributed with respect to any Shares subject to
this Section 5 or into which such Shares thereby become convertible shall immediately be subject to this Section 5 and Section 3. Appropriate adjustments to reflect the distribution of such securities or property shall be made to the
number and/or class of Shares subject to this Section 5 and Section 3. 
 5.3 Registration Rights. The Subscriber
acknowledges that the Shares are being purchased pursuant to an exemption from the registration requirements of the Securities Act and will become freely tradable only after certain conditions are met or they are registered pursuant to a
registration rights agreement to be entered into with the Company prior to the closing of the IPO. 
 6. Other Agreements. 

6.1 Further Assurances. The Subscriber agrees to execute such further instruments and to take such further action as may reasonably be
necessary to carry out the intent of this Agreement. 
 6.2 Notices. All notices, statements or other documents which are required or
contemplated by this Agreement shall be in writing and delivered: (i) personally or sent by first class registered or certified mail, overnight courier service or facsimile or electronic transmission to the address designated in writing,
(ii) by facsimile to the number most recently provided to such party or such other address or fax number as may be designated in writing by such party or (iii) by electronic mail, to the electronic mail address most recently provided to
such party or such other electronic mail address as may be designated in writing by such party. Any notice or other communication so transmitted shall be deemed to have been given on the day of delivery,


  
 5 













 
if delivered personally, on the business day following receipt of written confirmation, if sent by facsimile or electronic transmission, one (1) business day after delivery to an overnight
courier service or five (5) days after mailing if sent by mail. 
 6.3 Entire Agreement. This Agreement, together with the
letter agreement dated as of the closing of the IPO between the Subscriber and the Company, substantially in the form included as an exhibit to the Registration Statement on Form S-1, embodies the entire
agreement and understanding between the Subscriber and the Company with respect to the subject matter hereof and supersedes all prior oral or written agreements and understandings relating to the subject matter hereof. No statement, representation,
warranty, covenant or agreement of any kind not expressly set forth in this Agreement shall affect, or be used to interpret, change or restrict, the express terms and provisions of this Agreement. 

6.4 Modifications and Amendments. The terms and provisions of this Agreement may be modified or amended only by written agreement
executed by all parties hereto. 
 6.5 Waivers and Consents. The terms and provisions of this Agreement may be waived, or consent for
the departure therefrom granted, only by a written document executed by the party entitled to the benefits of such terms or provisions. No such waiver or consent shall be deemed to be or shall constitute a waiver or consent with respect to any other
terms or provisions of this Agreement, whether or not similar. Each such waiver or consent shall be effective only in the specific instance and for the purpose for which it was given, and shall not constitute a continuing waiver or consent. 

6.6 Assignment. The rights and obligations under this Agreement may not be assigned by either party hereto without the prior written
consent of the other party. 
 6.7 Benefit. All statements, representations, warranties, covenants and agreements in this Agreement
shall be binding on the parties hereto and shall inure to the benefit of the respective successors and permitted assigns of each party hereto. Nothing in this Agreement shall be construed to create any rights or obligations except among the parties
hereto, and no person or entity shall be regarded as a third-party beneficiary of this Agreement. 
 6.8 Governing Law. This
Agreement and the rights and obligations of the parties hereunder shall be construed in accordance with and governed by the laws of the State of New York applicable to contracts wholly performed within the borders of such state, without giving
effect to the conflict of law principles thereof. 
 6.9 Severability. In the event that any court of competent jurisdiction shall
determine that any provision, or any portion thereof, contained in this Agreement shall be unreasonable or unenforceable in any respect, then such provision shall be deemed limited to the extent that such court deems it reasonable and enforceable,
and as so limited shall remain in full force and effect. In the event that such court shall deem any such provision, or portion thereof, wholly unenforceable, the remaining provisions of this Agreement shall nevertheless remain in full force and
effect. 
 6.10 No Waiver of Rights, Powers and Remedies. No failure or delay by a party hereto in exercising any right, power or
remedy under this Agreement, and no course of dealing between 

  
 6 













 
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 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 Agreement shall entitle the party receiving such notice or demand to
any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the party giving such notice or demand to any other or further action in any circumstances without such notice or demand. 

6.11 Survival of Representations and Warranties. All representations and warranties made by the parties hereto in this Agreement or in
any other agreement, certificate or instrument provided for or contemplated hereby, shall survive the execution and delivery hereof and any investigations made by or on behalf of the parties. 

6.12 No Broker or Finder. Each of the parties hereto represents and warrants to the other that no broker, finder or other financial
consultant has acted on its behalf in connection with this Agreement or the transactions contemplated hereby in such a way as to create any liability on the other. Each of the parties hereto agrees to indemnify and save the other harmless from any
claim or demand for commission or other compensation by any broker, finder, financial consultant or similar agent claiming to have been employed by or on behalf of such party and to bear the cost of legal expenses incurred in defending against any
such claim. 
 6.13 Headings and Captions. The headings and captions of the various subdivisions of this Agreement are for
convenience of reference only and shall in no way modify or affect the meaning or construction of any of the terms or provisions hereof. 

6.14 Counterparts. This Agreement may be executed in one or more counterparts, all of which when taken together shall be considered one
and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign the same counterpart. In the event that any signature is
delivered by facsimile transmission or any other form of electronic delivery, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such
signature page were an original thereof. 
 6.15 Construction. The parties hereto have participated jointly in the negotiation and
drafting of this Agreement. If an ambiguity or question of intent or interpretation arises, this Agreement will be construed as if drafted jointly by the parties hereto and no presumption or burden of proof will arise favoring or disfavoring any
party hereto because of the authorship of any provision of this Agreement. The words “include,” “includes,” and “including” will be deemed to be followed by “without limitation.”
Pronouns in masculine, feminine, and neuter genders will be construed to include any other gender, and words in the singular form will be construed to include the plural and vice versa, unless the context otherwise requires. The words “this
Agreement,” “herein,” “hereof,” “hereby,” “hereunder,” and words of similar import refer to this Agreement as a whole and not to any particular subdivision unless expressly
so limited.

The parties hereto intend that each representation, warranty, and covenant contained herein will have independent significance. If any party hereto has breached any representation, warranty, or
covenant contained herein in any respect, the fact that there exists another representation, warranty or covenant relating to the same subject matter (regardless of the relative levels of specificity) which such party hereto has not breached will
not detract from or mitigate the fact that such party hereto is in breach of the first representation, warranty, or covenant. 
 6.16
Mutual Drafting. This Agreement is the joint product of the Subscriber and the Company and each provision hereof has been subject to the mutual consultation, negotiation and agreement of such parties and shall not be construed for or against
any party hereto. 
 7. Voting and Tender of Shares. The Subscriber agrees to vote the Shares in favor of an initial business combination that the
Company negotiates and submits for approval to the Company’s shareholders and shall not seek redemption with respect to such Shares. Additionally, the Subscriber agrees not to tender any Shares in connection with a tender offer presented to the
Company’s shareholders in connection with an initial business combination negotiated by the Company.
