Except as set forth on the Schedule of Exceptions attached hereto as Exhibit A, the Company hereby represents and warrants the following as of the Execution Date:

2.1Organization and Good Standing and Qualifications.

Except as set forth on the Schedule of Exceptions, the Company does not own any outstanding capital stock of or control any other business entity. The Company is duly qualified as a foreign corporation to do business and is in good standing in every jurisdiction in which the nature of the business conducted or property owned or leased by it makes such qualification necessary, other than those in which the failure so to qualify or be in good standing would not have a Material Adverse Effect. For purposes of this Agreement, “Material Adverse Effect” shall mean the effect of a material adverse change in the business, operations, assets or financial condition of the Company and its Subsidiaries, taken as a whole.

2.2Authorization. (i) The Company has the requisite corporate power and authority to enter into and perform its obligations under this Agreement; (ii) the execution and delivery of this Agreement by the Company, the consummation by the Company of the transactions contemplated hereby and thereby and the issuance, sale and delivery of the Shares have been duly authorized by all necessary corporate action and no further consent or authorization of the Company, its Board of Directors (the “Board of Directors”) or stockholders is required; and (iii) this Agreement has been duly executed and delivered and constitutes a valid and binding obligation of the Company enforceable against the Company in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, securities, insolvency, or similar laws relating to, or affecting generally the enforcement of, creditors’ rights and remedies, or indemnification or by other equitable principles of general application.

2.3Valid Issuance of Shares. The issuance of the Shares has been duly authorized by all requisite corporate action. When the Shares are issued, sold and delivered in accordance with the terms of this Agreement for the consideration expressed herein, the Shares will be duly and validly issued and outstanding, fully paid, and nonassessable, and will be free of all liens and restrictions on transfer other than restrictions on transfer under applicable state and federal securities laws and the Investor shall be entitled to all rights accorded to a holder of shares of Common Stock. The Company has reserved a sufficient number of shares of Common Stock for issuance to the Investor in accordance with the Company’s obligations under this Agreement.

2.4No Conflict. The execution, delivery and performance of this Agreement, and any other document or instrument contemplated hereby, by the Company and the consummation by the Company of the transactions contemplated hereby, do not: (i) violate any provision of the Company’s Amended and Restated Certificate of Incorporation (the “Certificate of Incorporation”) or Amended and Restated Bylaws (the “Bylaws”), (ii) conflict with, or constitute a default (or an event which with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, any material agreement, mortgage, deed of trust, indenture, note, bond, license, lease agreement, instrument or obligation to which the Company is a party where such default or conflict would constitute a Material Adverse Effect, (iii) create or impose a lien, charge or encumbrance on any property of the Company under any agreement or any commitment to which the Company is a party or by which the Company is bound, which would constitute a Material Adverse Effect, (iv) result in a violation of any federal, state, local or foreign statute, rule, regulation, order, writ, judgment or decree (including federal and state securities laws and regulations) applicable to the Company or any of its subsidiaries or by which any property or asset of the Company are bound or affected where such violation would constitute a Material Adverse Effect, or (v) require any consent of any third-party that has not been obtained pursuant to any material contract to which the Company is subject or to which any of its assets, operations or management may be subject. The Company is not required under federal, state or local law, rule or regulation to obtain any consent, authorization or order of, or make any filing or registration with, any court or governmental agency in order for it to execute, deliver or perform any of its obligations under this Agreement or issue and sell the Shares in accordance with the terms hereof (other than any filings that may be required to be made by the Company with the Securities and Exchange Commission (the “Commission”), the Nasdaq Global Market (the “Nasdaq Market”) or state securities commissions, each of which the Company has filed or undertakes to file not later than the applicable due date thereof); provided that, for purposes of the representation made in this sentence, the Company is assuming and relying upon the accuracy of the relevant representations and agreements of the Investor herein.

2.5Compliance. The Company is not, and the execution and delivery of this Agreement and the consummation of the transactions contemplated herewith will not cause the Company to be (i) in violation or default of any provision of any instrument, mortgage, deed of trust, loan, contract, commitment filed with the Commission Documents (as defined below), (ii) in violation of any provision of any judgment, decree, order or obligation to which it is a party or by which it or any of its properties or assets are bound, or (iii) in violation of any federal, state or, to its knowledge, local or foreign statute, rule or governmental regulation, in the case of each of clauses (i), (ii) and (iii), which would have a Material Adverse Effect.

The outstanding shares of capital stock of the Company have been duly and validly issued and are fully paid and nonassessable. The outstanding shares of capital stock of the Company were not issued in violation of any preemptive rights or similar rights to subscribe for or purchase securities and have been issued in compliance with all federal and state securities laws, in

each case except as would not reasonably be expected to have a Material Adverse Effect. Except as set forth in the Commission Documents, there are no outstanding rights (including, without limitation, preemptive rights), warrants or options to acquire, or instruments convertible into or exchangeable for, any unissued shares of capital stock or other equity interest in the Company, or any contract, commitment, agreement, understanding or arrangement of any kind to which the Company is a party and relating to the issuance or sale of any capital stock of the Company, any such convertible or exchangeable securities or any such rights, warrants or options. Without limiting the foregoing, no preemptive right, co-sale right, right of first refusal, or other similar right exists with respect to the Shares or the issuance and sale thereof. Except as disclosed in the Commission Documents, there are no stockholder agreements, voting agreements or other similar agreements with respect to the voting of the Shares to which the Company is a party or, to the knowledge of the Company, between or among any of the Company’s stockholders.

The Common Stock is currently listed or quoted on the Nasdaq Market.

As of their respective dates, the financial statements of the Company included in the Commission Documents filed with the Commission during the past twelve (12) months complied as to form and substance in all material respects with applicable accounting requirements and the published rules and regulations of the Commission or other applicable rules and regulations with respect thereto. Such financial statements have been prepared in accordance with generally accepted accounting principles (“GAAP”) applied on a consistent basis during the periods involved (except (i) as may be otherwise indicated in such financial statements or the notes thereto or (ii) in the case of unaudited interim statements, to the extent they may not include footnotes or may be condensed or summary statements), and fairly present in all material respects the financial position of the Company as of 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).

2.8Internal Controls and Procedures. The Company maintains disclosure controls and procedures as such terms are defined in, and required by, Rule 13a-15 and Rule 15d-15 under the Exchange Act.

Documents to ensure that all material information required to be disclosed by the Company in the reports that it files or furnishes under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Commission. The Company maintains a system of internal controls over financial reporting sufficient to provide reasonable assurance that (i) transactions are executed in accordance with management’s general or specific authorizations; and (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP.

2.9Material Adverse Change. Except as disclosed in the Commission Documents, since September 30, 2020, no event or series of events has or have occurred that would, individually or in the aggregate, have a Material Adverse Effect on the Company.

2.10No Undisclosed Liabilities. To the Company’s knowledge, neither the Company nor any of its subsidiaries has any liabilities, obligations, claims or losses (whether liquidated or unliquidated, secured or unsecured, absolute, accrued, contingent or otherwise) that would be required to be disclosed on a balance sheet of the Company or any of its subsidiaries (including the notes thereto) in conformity with GAAP and are not disclosed in the Commission Documents, other than those incurred in the ordinary course of the Company’s or its subsidiaries’ respective businesses since September 30, 2020.

2.11No Undisclosed Events or Circumstances. Except for the transactions contemplated by this Agreement and the Transaction Documents, no event or circumstance has occurred or exists with respect to the Company, its subsidiaries, or their respective businesses, properties, operations or financial condition, which, under applicable law, rule or regulation, requires public disclosure or announcement by the Company but which has not been so publicly announced or disclosed and which, individually or in the aggregate, would have a Material Adverse Effect on the Company.

2.12Actions Pending. There is no action, suit, claim, investigation or proceeding pending or, to the knowledge of the Company, threatened against the Company or any subsidiary which questions the validity of this Agreement or the transactions contemplated hereby or any action taken or to be taken pursuant hereto. Except as set forth in the Commission Documents, there is no action, suit, claim, investigation or proceeding pending or, to the knowledge of the Company, threatened, against or involving the Company, any subsidiary, or any of their respective properties or assets that could be reasonably expected to have a Material Adverse Effect on the Company. Except as set forth in the Commission Documents, no judgment, order, writ, injunction or decree or award has been issued by or, to the knowledge of the Company, requested of any court, arbitrator or governmental agency which could be reasonably expected to result in a Material Adverse Effect.

2.13Compliance with Law. The businesses of the Company and its subsidiaries have been and are presently being conducted in accordance with all applicable federal, state, local and foreign governmental laws, rules, regulations and ordinances, except as would not reasonably be expected to cause a Material Adverse Effect. The Company and each of its subsidiaries have all franchises, permits, licenses, consents and other governmental or regulatory authorizations and approvals necessary for the conduct of its business as now being conducted by it, except for such franchises, permits, licenses, consents and other governmental or regulatory authorizations and

approvals, the failure to possess which, individually or in the aggregate, could not reasonably be expected to have a Material Adverse Effect.

2.14Exemption from Registration, Valid Issuance. Subject to, and in reliance on, the representations, warranties and covenants made herein by the Investor, the issuance and sale of the Shares in accordance with the terms and on the bases of the representations and warranties set forth in this Agreement, may and shall be properly issued pursuant to Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”), Regulation D promulgated pursuant to the Securities Act (“Regulation D”) and/or any other applicable federal and state securities laws.

The Company shall be responsible for the fees of its Transfer Agent and all Depositary Trust Company fees associated with such issuance.

(c)In addition to the Investor’s other available remedies, if the Company fails to (i) issue and deliver (or cause to be delivered) to the Investor by the trading day that is five (5) Business Days after the Legend Removal Date the Shares and (ii) if after the Legend Removal Date, the Investor purchases (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of an actual sale by the Investor of all or any portion of the Shares as to which the Investor anticipated receiving from the Company pursuant to Section 6.2(b), then the Company shall pay the Investor, in cash, an amount equal to the excess, if any, of the Investor’s total purchase price (including brokerage commissions and other out-of-pocket expenses, if any) for the shares of Common Stock so purchased over the product of (i) a commensurate number of Shares as to which the Company was required to deliver to the Investor by the Legend Removal Date pursuant to Section 6.2(b) multiplied by (ii) the lowest closing sale price of the Common Stock on any trading day during the period commencing on the Legend Removal Date and ending on the date of delivery of such Shares by Company to the Investor pursuant to Section 6.2(b).

The words ‘execution’, ‘signed’, ‘signature’, ‘delivery’ and words of like import in or relating to any document to be signed in connection with this Agreement or any other Transaction Document and the transactions contemplated hereby shall be deemed to include Electronic Signatures, deliveries or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature, physical delivery thereof or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any Applicable Law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, or any other similar State laws based on the Uniform Electronic Transactions Act; provided, that nothing herein shall require any Person to accept electronic signatures in any form or format without its prior written consent. Without limiting the generality of the foregoing, the parties hereto hereby (a) agree that, for all purposes, including in connection with any workout, restructuring, enforcement of remedies, bankruptcy proceedings or litigation among the Purchasers and the Obligors, electronic images of this Agreement or any other Transaction Document (in each case, including with respect to any signature pages thereto) shall have the same legal effect, validity and enforceability as any paper original, and (b) waive any argument,

defense or right to contest the validity or enforceability of the Transaction Documents based solely on the lack of paper original copies of any Transaction Documents, including with respect to any signature pages thereto.

7.10Severability. If any provision of this Agreement is held to be invalid or unenforceable, the remaining provisions shall nevertheless be given full force and effect.

7.11Entire Agreement. This Agreement, together with the Exhibits hereto (which are incorporated herein by reference), and the other Transaction Documents constitute the entire agreement between the parties with respect to the subject matter hereof and supersede all prior agreements, understandings and negotiations, both written and oral, between the parties with respect to the subject matter of this Agreement. No representation, inducement, promise, understanding, condition or warranty not set forth herein (or in the Exhibits or other Transaction Documents) has been made or relied upon by either party hereto. None of this Agreement, nor any provision hereof, is intended to confer upon any Person other than the parties hereto any rights or remedies hereunder.

7.12Amendment; No Waivers. This Agreement or any term or provision hereof may not be amended, changed or modified except with the written consent of the Company and the Investor. No waiver of any right hereunder shall be effective unless such waiver is signed in writing by the party against whom such waiver is sought to be enforced. No failure or delay by either party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by law.

IN WITNESS WHEREOF, the parties have executed this Common Stock Purchase Agreement as of the date first set forth above.
