4.1. Organization, Good Standing and Qualification. The Company is a corporation duly organized, validly existing and in good standing
under the laws of the jurisdiction of its incorporation and has all requisite corporate power and authority to carry on its business as now conducted and to own or lease its properties. The Company is duly qualified to do business as a foreign
corporation and is in good standing in each jurisdiction in which the conduct of its business or its ownership or leasing of property makes such qualification or leasing necessary unless the failure to so qualify has not had and would not reasonably
be expected to have a Material Adverse Effect. The Company’s subsidiaries are set forth on Exhibit 21.1 to its most recent Annual Report on Form 10-K, and the Company owns 100% of the outstanding equity
of all such subsidiaries. The Company’s subsidiaries are duly organized, validly existing and in good standing under the laws of their jurisdiction of incorporation and have all requisite power and authority to carry on their business as now
conducted and to own or lease their properties. The Company’s subsidiaries are duly qualified to do business as foreign corporations and are in good standing in each jurisdiction in which the conduct of their business or their ownership or
leasing of property makes such qualification or leasing necessary unless the failure to so qualify has not had and would not reasonably be expected to have a Material Adverse Effect. 

4.2. Authorization. The Company has the requisite corporate power and authority and has taken all requisite corporate action necessary
for, and no further action on the part of the Company, its officers, directors and stockholders is necessary for, (i) the authorization, execution and delivery of the Transaction Documents, (ii) the authorization of the performance of all
obligations of the Company hereunder or thereunder, and (iii) the authorization, issuance (or reservation for issuance) and delivery of the Shares to each Investor, subject to obtaining Stockholder Approval. The Transaction Documents constitute
the legal, valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability,
relating to or affecting creditors’ rights generally and to general equitable principles. 
 4.3. Capitalization. The Company is
authorized under its Certificate of Incorporation to issue 300,000,000 shares of Common Stock. The Company’s disclosure of its issued and outstanding capital stock in its most recent SEC Filing containing such disclosure was accurate in all
material respects as of the date indicated in such SEC Filing. All of the issued and outstanding shares of the Company’s capital stock have been duly authorized and validly issued and are fully paid and nonassessable; none of such shares were
issued in violation of any preemptive rights; and such shares were issued in compliance in all material respects with 











 
applicable state and federal securities law and any rights of third parties. No Person is entitled to preemptive or similar statutory or contractual rights with respect to the issuance by the
Company of any securities of the Company, including, without limitation, the Shares. Except for (a) stock options and restricted stock units approved pursuant to Company stock-based compensation plans described in the SEC Filings and
(b) warrants disclosed in the SEC Filings, there are no outstanding warrants, options, convertible securities or other rights, agreements or arrangements of any character under which the Company is or may be obligated to issue any equity

with the registration of securities of the Company for its own account or for the account of any other Person or (b) prohibit the Company from filing a registration statement under the 1933 Act. 

The issuance and sale of the Shares hereunder will not obligate the Company to issue shares of Common Stock or other securities to any other
Person (other than the Investors) and will not result in the adjustment of the exercise, conversion, exchange or reset price of any outstanding security. 

The Company does not have outstanding stockholder purchase rights or “poison pill” or any similar arrangement in effect giving any
Person the right to purchase any equity interest in the Company upon the occurrence of certain events. 
 4.4. Valid Issuance.
Subject to receipt of the Stockholder Approval, the Shares will be duly and validly authorized and, when issued and paid for pursuant to this Agreement, will be validly issued, fully paid and nonassessable, and shall be free and clear of all

Shares and the ownership, disposition or voting of the Shares by the Investors or the exercise of any right granted to the Investors pursuant to this Agreement or the other Transaction Documents.

their respective terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability, relating to or affecting creditors’ rights generally, and general principles of equity. 

5.3. Purchase Entirely for Own Account. The Shares to be received by such Investor hereunder will be acquired for such Investor’s
own account, not as nominee or agent, for the purpose of investment and not with a view to the resale or distribution of any part thereof in violation of the 1933 Act, and such Investor has no present intention of selling, granting any participation
in, or otherwise distributing the same in violation of the 1933 Act without prejudice, however, to such Investor’s right at all times to sell or otherwise dispose of all or any part of such Shares in compliance with applicable federal and state
securities laws. The Shares are being purchased by such Investor in the ordinary course of its business. Nothing contained herein shall be deemed a representation or warranty by such Investor to hold the Shares for any period of time. Such Investor
is not a broker-dealer registered with the SEC under the 1934 Act or an entity engaged in a business that would require it to be so registered. 

5.4. Investment Experience. Such Investor acknowledges that it can bear the economic risk and complete loss of its investment in the
Shares and has such knowledge and experience in financial or business matters that it is capable of evaluating the merits and risks of the investment contemplated hereby. 

5.5. Disclosure of Information. Such Investor has had an opportunity to receive, review and understand all information related to the
Company requested by it and to ask questions of and receive answers from the Company regarding the Company, its business and the terms and conditions of the offering of the Shares, and has conducted and completed its own independent due diligence.
Such Investor acknowledges that copies of the SEC Filings are available on the EDGAR system. Based on the information such Investor has deemed appropriate, and without reliance upon the Placement Agent, it has independently made its own analysis and
decision to enter into the Transaction Documents. Such Investor is relying exclusively on its own investment analysis and due diligence (including professional advice it deems appropriate) with respect to the execution, delivery and performance of
the Transaction Documents, the Shares and the business, condition (financial and otherwise), management, operations, properties and prospects of the Company, including but not limited to all business, legal, regulatory, accounting, credit and tax
matters. Such Investor has not relied on any information or advice furnished by or on behalf of the Placement Agent in connection with the transactions contemplated hereby. Neither such inquiries nor any other due diligence investigation conducted
by such Investor shall modify, limit or otherwise affect such Investor’s right to rely on the Company’s representations and warranties contained in this Agreement. 











 5.6. Restricted Securities. Such Investor understands that the Shares are
characterized as “restricted securities” under the U.S. federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that under such laws and applicable regulations such
securities may be resold without registration under the 1933 Act only in certain limited circumstances. 
 5.7. Legends. It is
understood that, except as provided below, certificates or book-entry records evidencing the Shares may bear the following or any similar legend:

(ii) the business, affairs, financial condition, operations, properties or prospects of, or any other matter concerning the Company, (e) the Placement Agent will not have any liability or obligation (including without limitation, for or
with respect to any losses, claims, damages, obligations, penalties, judgments, awards, liabilities, costs, expenses or disbursements incurred by such Investor, the Company or any other person or entity), whether in contract, tort or otherwise, to
such Investor, or to any person claiming through it, in respect of the execution, delivery and performance of the Transaction Documents and (f) the Placement Agent and its directors, officers, employees, representatives and controlling persons
have made no independent investigation with respect to the Company or the Shares or the accuracy, completeness or adequacy of any information supplied to the Placement Agent by the Company.

solicitation or general advertising, or publicly disseminated advertisements or sales literature, including (a) any advertisement, article, notice or other communication published in any newspaper, magazine, website, or similar media, or
broadcast over television or radio, or (b) any seminar or meeting to which such Investor was invited by any of the foregoing means of communications.

5.12. Short Sales and Confidentiality Prior to the Date Hereof. Other than consummating the transactions contemplated hereunder, such
Investor has not, nor has any Person acting on behalf of or pursuant to any understanding with such Investor, directly or indirectly executed any purchases or sales, including Short Sales, of the securities of the Company during the period
commencing as of the time that such Investor was first contacted by the Company, the Placement Agent or any other Person regarding the transactions contemplated hereby and ending immediately prior to the date hereof. Notwithstanding the
foregoing, in the case of an Investor that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Investor’s assets and the portfolio managers have no direct knowledge of the investment
decisions made by the portfolio managers managing other 











 
portions of such Investor’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 Shares covered by this Agreement. Other than to other Persons party to this Agreement and other than to such Person’s outside attorney, accountant, auditor or investment advisor only to the extent necessary to
permit evaluation of the investment, and the performance of the necessary or required tax, accounting, financial, legal, or administrative tasks and services and other than as may be required by law, such Investor has maintained the confidentiality
of all disclosures made to it in connection with this transaction (including the existence and terms of this transaction). Notwithstanding the foregoing, for avoidance of doubt, nothing contained herein shall constitute a representation or warranty,
or preclude any actions, with respect to the identification of the availability of, or securing of, available shares to borrow in order to effect Short Sales or similar transactions in the future. 

5.13. No Government Recommendation or Approval. Such Investor understands that no United States federal or state agency, or similar
agency of any other country, has reviewed, approved, passed upon, or made any recommendation or endorsement of the Company or the purchase of the Shares.

Investor of the transactions contemplated hereby and thereby will not (i) result in a violation of the organizational documents of such Investor, (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 agreement, indenture or instrument to which such Investor is a party, or (iii) result in a violation of any law,
rule, regulation, order, judgment or decree (including federal and state securities laws) applicable to such Investor, except in the case of clauses (ii) and (iii) above, for such conflicts, defaults, rights or violations which would not,
individually or in the aggregate, reasonably be expected to have a material adverse effect on the ability of such Investor to perform its obligations hereunder.

9.5. Expenses. The parties hereto shall pay their own costs and expenses in connection herewith regardless of whether the transactions
contemplated hereby are consummated; it being understood that each of the Company and each Investor has relied on the advice of its own respective counsel. For the avoidance of doubt, the Company shall be responsible for any fees or commissions
payable to the Placement Agent. 
 9.6. Amendments and Waivers. Prior to Closing, no amendment or waiver of any provision of this
Agreement will be effective with respect to any party unless made in writing and signed by a duly authorized representative of such party. Following the Closing, any term of this Agreement may be amended and the observance of any term of this
Agreement may be waived (either generally or in a particular instance and either retroactively or prospectively) only with the written consent of the Company and the Investor Majority. Notwithstanding the foregoing, this Agreement may not be amended
and the observance of any term of this Agreement may not be waived with respect to any Investor without the written consent of such Investor unless such amendment or waiver applies to all Investors in the same fashion. Any amendment or waiver
effected in accordance with this paragraph shall be binding upon (i) prior to Closing, each Investor that signed such amendment or waiver and (ii) following the Closing, each holder of any Shares purchased under this Agreement at the time
outstanding and the Company. 
 9.7. Publicity. Except as set forth below, no public release or announcement concerning the
transactions contemplated hereby shall be issued by the Investors prior to Closing without the prior consent of the Company, except as such release or announcement may be required by law or the applicable rules or regulations of any securities
exchange or securities market, in which case the Investors shall allow the Company reasonable time to comment on such release or announcement in advance of such issuance. Notwithstanding the foregoing, each Investor may identify the Company and the
value of such Investor’s security holdings in the Company in accordance with applicable investment reporting and disclosure regulations or internal policies without prior notice to or consent from the Company (including, for the avoidance of
doubt, filings pursuant to Sections 13 and 16 of the 1934 Act). The Company shall not include the name of any Investor or any Affiliate or investment adviser of such Investor in any press release or public announcement (which, for the avoidance of
doubt, shall not include any SEC Filing to the extent such disclosure is required by SEC rules and regulations) without the prior written consent of such Investor. No later than the Business Day immediately following the date this Agreement is
executed, the Company shall issue a press release (the “Press Release”) and/or file a Form 8-K disclosing all material terms of the sale of the Shares to the Investors pursuant to this
Agreement and any material non-public information that the Company may have provided any Investor in connection with the transactions contemplated by this Agreement. In addition, the Company will make such
other filings and notices in the manner and time required by the SEC or Nasdaq. 











 9.8. Severability. Any provision of this Agreement that is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof but shall be interpreted as if it were written so as to be
enforceable to the maximum extent permitted by applicable law, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. To the extent permitted by
applicable law, the parties hereby waive any provision of law which renders any provision hereof prohibited or unenforceable in any respect. 

9.9. Benefit of Agreement. The Placement Agent is an intended third-party beneficiary of Section 9.14 of this Agreement and of the
representations and warranties of the Company and of each Investor set forth in Section 4 and Section 5, respectively, of this Agreement. 

9.10. Entire Agreement. This Agreement, including the signature pages, Exhibits, the other Transaction Documents and the Confidentiality
Agreement between the Company and each Investor constitute the entire agreement among the parties hereof with respect to the subject matter hereof and thereof and supersede all prior agreements and understandings, both oral and written, between the
parties with respect to the subject matter hereof and thereof. 
 9.11. Further Assurances. The parties shall execute and deliver all
such further instruments and documents and take all such other actions as may reasonably be required to carry out the transactions contemplated hereby and to evidence the fulfillment of the agreements herein contained. 

9.12. Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York. Service
of process in connection with any such suit, action or proceeding may be served on each party hereto anywhere in the world by the same methods as are specified for the giving of notices under this Agreement. 

9.13. Independent Nature of Investors’ Obligations and Rights. The obligations of each Investor under any Transaction Document are
several and not joint with the obligations of any other Investor, and no Investor shall be responsible in any way for the performance of the obligations of any other Investor under any Transaction Document. The decision of each Investor to purchase
Shares pursuant to the Transaction Documents has been made by such Investor independently of any other Investor. Nothing contained herein or in any Transaction Document, and no action taken by any Investor pursuant thereto, shall be deemed to
constitute the Investors as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Investors are in any way acting in concert or as a group with respect to such obligations or the transactions
contemplated by the Transaction Documents. Each Investor acknowledges that no other Investor has acted as agent for such Investor in connection with making its investment hereunder and that no Investor will be acting as agent of such Investor in
connection with monitoring its investment in the Shares or enforcing its rights under the Transaction Documents. Each Investor shall be entitled to independently protect and enforce its rights, including, without limitation, the rights arising out
of this Agreement or out of the other Transaction Documents, and it shall not be necessary for any other Investor to be joined as an 











 
additional party in any proceeding for such purpose. The Company acknowledges that each of the Investors has been provided with the same Transaction Documents for the purpose of closing a
transaction with multiple Investors and not because it was required or requested to do so by any Investor. It is expressly understood and agreed that each provision contained in this Agreement is between the Company and an Investor, solely, and not
between the Company and the Investors collectively and not between and among the Investors. 
 9.14. Exculpation of the Placement
Agent. Each party hereto agrees for the express benefit of the Placements Agent and its affiliates and representatives that: 
 (i) none
of the Placement Agent, its affiliates or any of its representatives (1) has any duties or obligations other than those specifically set forth herein or in the engagement letter, dated September 9, 2022 (the “Engagement
Letter”), between the Company and the Placement Agent; (2) shall be liable for any improper payment made in accordance with the information provided by the Company; (3) makes any representation or warranty, or has any
responsibilities as to the validity, accuracy, value or genuineness of any information, certificates or documentation delivered by or on behalf of the Company pursuant to this Agreement or the Transaction Documents or in connection with any of the
transactions contemplated hereby and thereby; or (4) shall be liable (x) for any action taken, suffered or omitted by any of them in good faith and reasonably believed to be authorized or within the discretion or rights or powers conferred
upon it by this Agreement or any Transaction Document or (y) for anything which any of them may do or refrain from doing in connection with this Agreement or any Transaction Document, except in each case for such party’s own gross
negligence, fraud, willful misconduct or bad faith. 
 (ii) The Placement Agent, its affiliates and its representatives shall be entitled to
(1) rely on, and shall be protected in acting upon, any certificate, instrument, notice, letter or any other document or security delivered to any of them by or on behalf of the Company, and (2) be indemnified by the Company for acting as
the Placement Agent hereunder pursuant to the indemnification provisions set forth in the Engagement Letter.
