Each Unit consists of (i) two (2) shares of common stock (the “Shares”), par value $0.001 per share, of the Company (the “Common Stock”), and (ii) one warrant to purchase one share of Common Stock (the “Warrant Shares”) at an initial per share exercise price equal to $4.50 (each a “Warrant” and collectively, the “Warrants”), which will terminate seven years following the initial closing of the Offering (as defined below).

This subscription is submitted to the Purchaser in accordance with and subject to the terms and conditions described in this Subscription Agreement and the Confidential Private Placement Memorandum of the Company, dated November 14, 2022, as amended or supplemented from time to time, including all attachments, schedules and exhibits thereto (the “Memorandum”), relating to the private placement offering (the “Offering”) by the Company of up to 5,405,405 Units with an aggregate maximum purchase price of $25.0 million. The Units are being offered by the Company and Lake Street Capital Markets, LLC (the “Broker”) on a “reasonable best efforts” basis. The minimum purchase amount is 2,162,162 Units ($10.0 million), although the Company may, in its discretion, accept subscriptions for a lesser number of Units.

The Broker will receive a cash commission equal to 5.0% of the gross proceeds from the sale of the Units (the “Commission”) as further described in the Placement Agent Agreement between the Company and the Broker.

The terms of the Offering are more completely described in the Memorandum and such terms are incorporated by reference herein in their entirety. Capitalized terms not otherwise defined herein shall have the meanings ascribed to such terms in the Memorandum.

Wire transfer instructions are set forth on Schedule 1 accompanying this Subscription Agreement. Such funds will be returned promptly, without interest or offset, if the Purchaser’s subscription is not accepted by the Company for any reason or no reason, or the Offering is terminated pursuant to its terms by the Company prior to the applicable closing of the Offering.

3. Deposit of Funds. The Company shall hold all funds in escrow until such time as it closes on the corresponding subscriptions. If the Company rejects a subscription, either in whole or in part (which decision is in the Company’s sole discretion), the rejected subscription funds or the rejected portion thereof will be returned promptly to the Purchaser without interest accrued thereon.

The Company shall have no obligation hereunder until this Subscription Amount is received by the Company and the Company has executed and delivered to the Purchaser a fully executed and compiled copy of this Subscription Agreement. If such Purchaser’s subscription is rejected in whole or the Offering is terminated, all funds received from the Purchaser will be returned without interest or offset, and this Subscription Agreement shall thereafter be of no further force or effect.

6. Representations and Warranties of the Purchaser. Each Purchaser, for itself and no other Purchaser, hereby acknowledges, represents, warrants and agrees to and with the Company as follows (it being specifically acknowledged and agreed that the Broker shall be a third-party beneficiary of the following):

(a)The Purchaser is aware that an investment in the Units involves a significant degree of risk and has carefully read and considered the matters set forth in the Memorandum, including but not limited to the section entitled “Risk Factors” in the Memorandum, and the Company’s filings with the Securities and Exchange Commission (the “SEC”).

(b) None of the securities comprising the Units, including the Shares and the Warrants offered pursuant to the Memorandum, or the Warrant Shares issuable upon conversion of the Warrants, are registered under the Securities Act of 1933, as amended (the “Securities Act”), or any state securities laws. The Purchaser understands that the offering and sale of the Units (including the Shares and the Warrants) and the Warrant Shares issuable upon conversion of the Warrants are intended to be exempt from registration under the Securities Act, by virtue of Section 4(a)(2) thereof and the provisions of Regulation D promulgated thereunder (“Regulation D”), based, in part, upon the representations, warranties and agreements of the Purchaser contained in this Subscription Agreement.

(c)At the time the Purchaser was offered the Units, it was, and at the date hereof it is, an “accredited investor” as defined in each of Rule 501(a) under the Securities Act and the Accredited Investor Certification attached hereto as Annex B. The Accredited Investor Certification is complete and accurate in all respects as of the date of this Subscription Agreement, and will continue to be complete and accurate as of the effectiveness date of any resale registration statement filed by the Company for the purpose of registering the securities contemplated by this Subscription Agreement (the “Resale Registration Statement”); provided, that the Purchaser shall be entitled to update such information by providing written notice thereof to the Company.

(d) Prior to the execution of this Subscription Agreement, the Purchaser and the Purchaser’s attorney, accountant, purchaser representative and/or tax adviser, if any (collectively, the “Advisers”), have received the Memorandum and all other documents requested by the Purchaser, have carefully reviewed such documents and the documents filed by the Company with the SEC, and understand the information contained therein.

(e)Neither the SEC nor any state securities commission or other regulatory authority has approved the Units, the Shares, the Warrants, or the Warrant Shares, or passed upon or endorsed the merits of the offering of Units, or confirmed the accuracy or determined the adequacy of the Memorandum. The Memorandum has not been reviewed by any federal, state or other regulatory authority.

(f)All documents, records, and books pertaining to the investment in the Units (including, without limitation, the Memorandum) have been made available for inspection by such Purchaser and its Advisers, if any.

(g)The Purchaser and its Advisers, if any, have had a reasonable opportunity to ask questions of and receive answers from a person or persons acting on behalf of the Company concerning the Offering and the business and financial condition of the Company, and all such questions have been answered to the full satisfaction of the Purchaser and its Advisers, if any.

(h)In evaluating the suitability of an investment in the Company, the Purchaser has not relied upon any representation or information (oral or written) other than as stated in or incorporated by reference into the Memorandum or any documents filed by the Company with the SEC.

(i)The Purchaser is unaware of, is in no way relying on, and did not become aware of the Offering through or as a result of, any form of general solicitation or general advertising including, without limitation, any article, notice, advertisement or other communication published in any newspaper, magazine or similar media or broadcast over television, radio or the Internet (including, without limitation, the Company’s or SEC’s website, Internet “blogs,” bulletin boards, discussion groups and social networking sites) in connection with the Offering and is not subscribing for the Units and did not become aware of the Offering through or as a result of any seminar or meeting to which the Purchaser was invited by, or any solicitation of a subscription by, a person not previously known to the Purchaser in connection with investments in securities generally.

(j)The Purchaser has taken no action that would give rise to any claim by any person for brokerage commissions, finders’ fees or the like relating to this Subscription Agreement or the transactions contemplated hereby (other than the Commission and expenses to be paid or reimbursed by the Company to the Broker or as otherwise described in the Memorandum) and, in turn, to be paid to its selected dealers.

(k)The Purchaser, together with its Advisers, if any, has such knowledge and experience in financial, tax, and business matters, and, in particular, investments in securities, so as to enable it to utilize the information made available to it in connection with the Offering to evaluate the merits and risks of an investment in the Units and the Company and to make an informed investment decision with respect thereto.

(l)The Purchaser is not relying on the Company, the Broker, or any of their respective employees or agents with respect to the legal, tax, economic and related considerations of an investment in the Units, and the Purchaser has relied on the advice of, or has consulted with, only its own Advisers.

(m)The Purchaser is acquiring the Units and, upon exercise of the Warrants, will acquire the Warrant Shares, as principal for its own account and not with a view to, or for distributing or reselling such securities or any part thereof in violation of the Securities Act or any applicable state securities laws; provided, however, that by making the representations herein, the Purchaser reserves the right, subject to the provisions of this Subscription Agreement and the Registration Rights Agreement, at all times to sell or otherwise dispose of all or any part of such securities pursuant to the Resale Registration Statement under the Securities Act or under an exemption from such registration and in compliance with applicable federal and state securities laws. The Purchaser is acquiring the Units hereunder in the ordinary course of its business. The Purchaser does not presently have any agreement, plan or understanding, directly or indirectly, with any person to distribute or effect any distribution of any of the Units, Shares, Warrants or Warrant Shares issuable upon exercise of the Warrants (or any securities which are derivatives thereof) to or through any person or entity; the Purchaser is not a registered broker-dealer under Section 15 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or an entity engaged in a business that would require it to be so registered as a broker-dealer. Legends shall be placed on the securities included in the Units to the effect that they have not been registered under the Securities Act or applicable state securities laws. Appropriate notations will be made in the Company’s securities ledgers to the effect that the securities included in the Units have not been registered under the Securities Act or applicable state securities laws. Stop transfer instructions will be placed with the Company’s transfer agent on the securities. There can be no assurance that there will be any market for resale of the Units, the Shares, the Warrants, or the Warrant Shares nor can there be any assurance that such securities will be freely transferable at any time in the foreseeable future.

(n)The Purchaser has adequate means of providing for such Purchaser’s current financial needs and foreseeable contingencies and has no need for liquidity of its investment in the Units for an indefinite period of time.

(o)The Purchaser (i) if a natural person, represents that the Purchaser has reached the age of 21 and has full power and authority to execute and deliver this Subscription Agreement and any other agreements, documents or instruments delivered or required to be delivered together with or pursuant to this Subscription Agreement or in connection herewith (the “Subscription Documents”) and to carry out the provisions hereof and thereof; (ii) if a corporation, partnership, or limited liability company or partnership, or association, joint stock company, trust, unincorporated organization or other entity, represents that such entity was not formed for the specific purpose of acquiring the Units, such entity is duly organized, validly existing and in good standing under the laws of the state of its organization, the consummation of the transactions contemplated hereby is authorized by, and will not result in a violation of state law or our charter or other organizational documents, such entity has full power and authority to execute and deliver the Subscription Documents and to carry out the provisions hereof and thereof and to purchase and hold the securities constituting the Units, the execution and delivery of the Subscription Documents have been duly authorized by all necessary action, the Subscription Documents to which it is a party have been duly executed and when delivered on behalf of such entity in accordance with the terms hereof, will constitute a legal, valid and binding obligation of such entity, enforceable against it in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, liquidation or similar laws relating to, or affecting generally the enforcement of, creditors’ rights and remedies or by other equitable principles of general application; or (iii) if executing the Subscription Documents in a representative or fiduciary capacity, represents that it has full power and authority to execute and deliver the Subscription Documents in such capacity and on behalf of the subscribing individual, ward, partnership, trust, estate, corporation, or limited liability company, or other entity for whom the Purchaser is executing the Subscription Documents, and such individual, partnership, ward, trust, estate, corporation, or limited liability company, or other entity has full right and power to execute and deliver the Subscription Documents and all other related agreements or certificates and to carry out the provisions hereof and thereof and to purchase and hold the securities constituting the Units, and represents that the Subscription Documents constitute a legal, valid and binding obligation of such entity. The execution, delivery and performance of this Subscription Agreement and the Registration Rights Agreement, and the consummation by the Purchaser of the transactions contemplated hereby and thereby will not (i) result in a violation of the organizational documents of the Purchaser (except as to any Purchaser who is a natural person), (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 the Purchaser 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 the Purchaser, 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 the Purchaser to perform its obligations hereunder.

(p)The Purchaser and its Advisers, if any, have had the opportunity to obtain any additional information, to the extent the Company had such information in its possession or could acquire it without unreasonable effort or expense, necessary to verify the accuracy of the information contained in the Memorandum and all documents received or reviewed in connection with the purchase of the Units and have had the opportunity to have representatives of the Company provide them with such additional information regarding the terms and conditions of this particular investment and the financial condition, results of operations, and business of the Company deemed relevant by the Purchaser or the Advisers, if any, and all such requested information, to the extent the Company had such information in its possession or could acquire it without unreasonable effort or expense, has been provided to the full satisfaction of the Purchaser and the Advisers, if any.

(q)Any information which the Purchaser has heretofore furnished or is furnishing herewith to the Company or the Broker is complete and accurate and may be relied upon by the Company and the Broker in determining the availability of an exemption from registration under federal and state securities laws in connection with the offering of securities as described in the Memorandum. The Purchaser further represents and warrants that it will notify and supply corrective information to the Company and the Broker immediately upon the occurrence of any change therein occurring prior to the Company’s issuance of the securities contained in the Units.

(r)The Purchaser has significant prior investment experience, including investment in non-registered, high risk securities. The Purchaser has a sufficient net worth to sustain a loss of its entire investment in the Company in the event such a loss should occur. The Purchaser’s overall commitment to investments which are not readily marketable is not excessive in view of the Purchaser’s net worth and financial circumstances and the purchase of the Units will not cause such commitment to become excessive. The investment is a suitable one for the Purchaser.

(s)The Purchaser is satisfied that the Purchaser has received adequate information with respect to all matters which it or its Advisers, if any, consider material to the Purchaser’s decision to make this investment.

(t)The Purchaser acknowledges that any estimates or forward-looking statements or projections included in the Memorandum or in any documents filed with or furnished to the SEC by the Company were prepared by the Company in good faith but that the attainment of any such projections, estimates or forward-looking statements cannot be guaranteed by the Company and should not be relied upon.

(u)No oral or written representations have been made, or oral or written information furnished, to the Purchaser or its Advisers, if any, in connection with the Offering which are in any way inconsistent with the information contained in the Memorandum or incorporated by reference in the Memorandum.

(v)Within five (5) days after receipt of a request from the Company, the Purchaser will provide such information and deliver such documents as may reasonably be necessary to comply with any and all laws and ordinances to which the Company is subject.

(w)NEITHER THE SECURITIES OFFERED HEREBY NOR THE SECURITIES ISSUABLE UPON EXERCISE OF THESE SECURITIES HAVE BEEN REGISTERED WITH THE SEC OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT, AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE TRANSFEROR TO SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL BE REASONABLY ACCEPTABLE TO THE COMPANY.

(x)The Purchaser acknowledges that none of the Units, the Shares, the Warrants, or the Warrant Shares issuable upon exercise of the Warrants have been recommended by any federal or state securities commission or regulatory authority. In making an investment decision, investors must rely on their own examination of the Company and the terms of the Offering, including the merits and risks involved. Furthermore, the foregoing authorities have not confirmed the accuracy or determined the adequacy of this Subscription Agreement or the Memorandum. Any representation to the contrary is a criminal offense. The Units, the Shares, the Warrants, and the Warrant Shares issuable upon exercise of the Warrants are subject to restrictions on transferability and resale and may not be transferred or resold except as permitted under the Securities Act, and the applicable state securities laws, pursuant to registration or exemption therefrom. The Purchaser is aware that it will be required to bear the financial risks of this investment for an indefinite period of time.

(y)(For ERISA plans only) The fiduciary of the ERISA plan (the “Plan”) represents that such fiduciary has been informed of and understands the Company’s investment objectives, policies, and strategies, and that the decision to invest “plan assets” (as such term is defined in ERISA) in the Company is consistent with the provisions of ERISA that require diversification of plan assets and impose other fiduciary responsibilities. The Purchaser fiduciary or Plan (i) is responsible for the decision to invest in the Company; (ii) is independent of the Company or any of its affiliates; (iii) is qualified to make such investment decision; and (iv) in making such decision, the Purchaser fiduciary or Plan has not relied primarily on any advice or recommendation of the Company or any of its affiliates.

(z)The Purchaser should check the U.S. Office of Foreign Assets Control website before making the following representations. The Purchaser represents that the amounts invested by it in the Offering were not and are not directly or indirectly derived from activities that contravene federal, state or international laws and regulations, including anti-money laundering laws and regulations. Federal regulations and Executive Orders administered by the U.S. Office of Foreign Assets Control (“OFAC”) prohibit, among other things, the engagement in transactions with, and the provision of services to, certain foreign countries, territories, entities and individuals. The lists of OFAC prohibited countries, territories, persons and entities can be found on the OFAC website at http://www.treas.gov/ofac. In addition, the programs administered by OFAC (the “OFAC

Programs”) prohibit dealing with individuals¹ or entities in certain countries regardless of whether such individuals or entities appear on the OFAC lists.

(aa)None of: (1) the Purchaser; (2) any person controlling or controlled by the Purchaser; (3) if the Purchaser is a privately-held entity, any person having a beneficial interest in the Purchaser; or (4) any person for whom the Purchaser is acting as agent or nominee in connection with this investment is a country, territory, individual or entity named on an OFAC list, or a person or entity prohibited under the OFAC Programs. Please be advised that the Company may not accept any amounts from a prospective investor if such prospective investor cannot make the representation set forth in the preceding sentence. The Purchaser agrees to promptly notify the Company and the Broker should the Purchaser become aware of any change in the information set forth in these representations. The Purchaser understands and acknowledges that, by law, the Company may be obligated to “freeze the account” of the Purchaser, either by prohibiting additional subscriptions from the Purchaser, declining any redemption requests and/or segregating the assets in the account in compliance with governmental regulations, and the Broker may also be required to report such action and to disclose the Purchaser’s identity to OFAC. The Purchaser further acknowledges that the Company may, by written notice to the Purchaser, suspend the redemption rights, if any, of the Purchaser if the Company reasonably deems it necessary to do so to comply with anti-money laundering regulations applicable to the Company and the Broker or any of the Company’s other service providers. These individuals include specially designated nationals, specially designated narcotics traffickers and other parties subject to OFAC sanctions and embargo programs.

(bb)None of: (1) the Purchaser; (2) any person controlling or controlled by the Purchaser; (3) if the Purchaser is a privately-held entity, any person having a beneficial interest in the Purchaser; or (4) any person for whom the Purchaser is acting as agent or nominee in connection with this investment is a senior foreign political figure,² or any immediate family³ member or close associate⁴ of a senior foreign political figure, as such terms are defined in the footnotes below.

(cc)If the Purchaser is affiliated with a non-U.S. banking institution (a “Foreign Bank”), or if the Purchaser receives deposits from, makes payments on behalf of, or handles other financial transactions related to a Foreign Bank, the Purchaser represents and warrants to the Company that: (1) the Foreign Bank has a fixed address, other than solely an electronic address, in a country in which the Foreign Bank is authorized to conduct banking activities; (2) the Foreign Bank maintains operating records related to its banking activities; (3) the Foreign Bank is subject to inspection by the banking authority that licensed the Foreign Bank to conduct banking activities; and (4) the Foreign Bank does not provide banking services to any other Foreign Bank that does not have a physical presence in any country and that is not a regulated affiliate.

(dd)Other than with respect to the transactions contemplated herein, since the time that such Purchaser was first contacted by the Company, a broker or any other person regarding the transactions contemplated hereby, none of (i) the Purchaser, (ii) any affiliate of such Purchaser that (x) had knowledge of the transactions contemplated hereby, (y) has or shares discretion relating to such Purchaser’s investments or trading or information concerning such Purchaser’s investments, including in respect of the Units, and (z) is subject to such Purchaser’s review or input concerning such affiliate’s investments or trading (collectively, “Trading Affiliates”) or (iii) any person acting on behalf of or pursuant to any understanding with such Purchaser or Trading Affiliate, has directly or indirectly effected or agreed to effect any purchases or sales of the securities of the Company (including, without limitation, any short sales involving the Company’s securities). Notwithstanding the foregoing, in the case of a Purchaser and/or Trading Affiliate that is, individually or collectively, a multi-managed investment bank or vehicle whereby separate portfolio managers manage separate portions of such Purchaser’s or Trading Affiliate’s assets and the portfolio managers have no direct knowledge of the investment decisions made by the portfolio managers managing other portions of such Purchaser’s or Trading Affiliate’s assets, the representation set forth above shall apply only with respect to the portion of assets managed by the portfolio manager that has knowledge about the financing transaction contemplated by this Subscription Agreement. Other than to other persons party to this

Subscription Agreement and prospective investors, such Purchaser has maintained the confidentiality of all disclosures made to it in connection with this transaction (including the existence and terms of this transaction).

(ee)The Purchaser is aware that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of Common Stock and other activities with respect to the Common Stock held by the Purchaser.

(ff)The purchase by the Purchaser of the Shares and Warrants issuable to it at closing will not result in the Purchaser (individually or together with any other person with whom such Purchaser has identified, or will have identified, itself as part of a “group” in a public filing made with the SEC involving the Company’s securities) acquiring, or obtaining the right to acquire, in excess of 19.99% of the outstanding shares of Common Stock or the voting power of the Company on a post-transaction basis that assumes that such closing shall have occurred. The Purchaser does not presently intend to, alone or together with others, make a public filing with the SEC to disclose that it has (or that it together with such other persons has) acquired, or obtained the right to acquire, as a result of such closing (when added to any other securities of the Company that it or they then own or have the right to acquire), in excess of 19.99% of the outstanding shares of Common Stock or the voting power of the Company on a post-transaction basis that assumes that each closing shall have occurred.

(gg)If the Purchaser is an officer of the Company or beneficial owner of 20% or more of the Company’s outstanding voting equity securities, such Purchaser does not qualify as a “bad actor” within the meaning of Rule 506(d) under the Securities Act.

7. Company Representations and Warranties. The Company represents and warrants to the Purchaser, except as and to the extent set forth in the publicly available reports, schedules, forms, statements and other documents filed by the Company with, or furnished by the Company to, the SEC (the “General Disclosure Package”) as of the date hereof and as of each closing:

The Company is duly qualified as a foreign corporation to do business and is in good standing in each jurisdiction where the nature of the business conducted or property owned by it makes such qualification necessary except to the extent as would not reasonably be likely to have a material adverse effect.

(b) The Company has all requisite corporate right, power and authority to enter into the Transaction Documents and to consummate the transactions contemplated hereby. All corporate action on the part of the Company, its directors and stockholders necessary for the: (i) authorization, execution, delivery and performance of the Transaction Documents by the Company; (ii) authorization, sale, issuance and delivery of the Units and securities comprising the Units contemplated hereby and the performance of the Company’s obligations hereunder; and (iii) authorization and reservation for issuance of the Warrant Shares issuable upon exercise of the Warrants, has been taken. When the Warrants are exercised in accordance with their terms, the Warrant Shares will be validly issued, fully paid and nonassessable. The issuance and sale of the securities contemplated hereby will not give rise to any preemptive rights or rights of first refusal on behalf of any person which have not been waived in connection with this Offering. The Company is not in default of any other obligations except as would not be reasonably expected to have a material adverse effect.

(c)Assuming this Subscription Agreement has been duly and validly authorized, executed and delivered by the parties hereto and thereto other than the Company, this Subscription Agreement is duly authorized, executed and delivered by the Company and constitutes the legal, valid and binding obligations of the Company enforceable against the Company in accordance with its terms, except as such enforcement is limited by general equitable principles, or by bankruptcy, insolvency and other similar laws affecting the enforcement of creditors rights generally.

(d)The execution, delivery and performance of this Subscription Agreement by the Company and the consummation by the Company of the transactions contemplated hereby and thereby (including, without limitation, the issuance of the Units and the Warrant Shares issuable upon exercise of the Warrants will not (i) result in a violation of the Certificate of Incorporation of the Company or other organizational documents of the Company, (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, acceleration or cancellation of, any agreement,

indenture, or instrument to which the Company is a party except as would not reasonably be expected to have a material adverse effect, or (iii) result in a violation of any law, rule, regulation, order, judgment or decree applicable to the Company by which any property or asset of the Company is bound or affected except as would not reasonably be expected to have a material adverse effect.

(e)The Company is not an “investment company” within the meaning of such term under the Investment Company Act of 1940, as amended, and the rules and regulations of the SEC promulgated thereunder.

(f)Neither the Company nor any person participating on the Company’s behalf in the transactions contemplated hereby has conducted any “general solicitation,” as such term is defined in Regulation D, with respect to any of the securities being offered hereby.

(g)The Company agrees to file a Form D with respect to the sale of the securities offered hereby under Regulation D of the rules and regulations promulgated under the Securities Act. The Company shall take such action as the Company shall reasonably determine is necessary to qualify the such securities for sale to the Purchaser pursuant to this Subscription Agreement under applicable securities or “blue sky” laws of the states of the United States (or to obtain an exemption from such qualification).

(h)Neither the Company, nor any of its affiliates, nor any person acting on its or their behalf, has directly or indirectly made any offers or sales in any security or solicited any offers to buy any security under circumstances that would require registration under the Securities Act of the issuance of the Units or Warrant Shares. The issuance of the Units and Warrant Shares will not be integrated with any other issuance of the Company’s securities (past, current or future) such that the offering of the Units or Warrant Shares would require registration under the Securities Act or would require stockholder approval pursuant to the Company’s Certificate of Incorporation or other organizational documents of the Company or the rules and regulations of Nasdaq.

(i)The execution, delivery and performance of this Subscription Agreement by the Company will not (i) violate any law, treaty, rule or regulation applicable to or binding upon the Company or any of its properties or assets, or (ii) result in a breach of any contractual obligation to which the Company is a party or by which it or any of its properties or assets is bound that would reasonably be expected to have a material adverse effect on the ability of the Company to perform its obligations under this Subscription Agreement and the Transaction Documents. 

8. Registration Rights. Contemporaneously with the execution and delivery of this Subscription Agreement, the parties hereto are executing and delivering a Registration Rights Agreement pursuant to which, among other things, the Company will agree to provide certain registration rights with respect to the Shares and the Warrant Shares under the Securities Act and the rules and regulations promulgated thereunder and applicable state securities laws.

19. Counsel. This Subscription Agreement and all the other Transaction Documents related to the Offering have been prepared by Fenwick & West LLP, as counsel to the Company (“Counsel”), after full disclosure of its representation of the Company and with the consent and direction of the Company and the Purchaser. The Purchaser acknowledges that he, she or it is fully aware of his, her or its right to the advice of counsel independent from that of the Company, that Counsel has advised the Purchaser of such right and disclosed to the Purchaser the risks in not seeking such independent advice, and that he, she or it understands the potentially adverse interests of the parties with respect to the Transaction Documents. The Purchaser further acknowledges that no representations have been made with respect to the tax or other consequences of the Transaction Documents to the Purchaser and that he, she or it has been advised of the importance of seeking independent counsel with respect to such consequences. By executing this Subscription Agreement, the Purchaser represents that he, she or it has, after being advised of the potential conflicts between the Purchaser and the Company with respect to the future consequences of the Transaction Documents, either consulted independent legal counsel or elected, notwithstanding the advisability of seeking such independent legal counsel, not to consult such independent legal counsel.

20. Miscellaneous.

(a) This Subscription Agreement (including the annexes hereto), together with the Transaction Documents (which are to be issued or executed at closing), constitutes the entire agreement between the Purchaser and the Company with respect to the subject matter hereof and supersedes all prior oral or written agreements and understandings, if any, relating to the subject matter hereof.

(d) This Subscription Agreement may be executed in one or more counterparts each of which shall be deemed an original (including signatures sent by facsimile transmission or by email transmission of a PDF scanned document), but all of which shall together constitute one and the same instrument.
