      Act and the Exchange Act, including pursuant to Section 13(a) or 15(d) thereof, for the twelve months preceding the date hereof (or such shorter period as the Company was required by law or regulation to file such material) (the foregoing materials,
      including the exhibits thereto and documents incorporated by reference therein, being collectively referred to herein as the “SEC Documents”) on a timely basis or has received a valid extension of such time of filing and has filed any such SEC
      Documents prior to the expiration of any such extension.  As of their respective dates and to the Company’s knowledge, the SEC Documents complied in all material respects with the requirements of the Securities Act and the Exchange Act, as
      applicable.   None of the SEC Documents, when filed, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the
      circumstances under which they were made, not misleading. The financial statements of the Company included in the SEC Documents comply in all material respects with applicable accounting requirements and the rules and regulations of the SEC with
      respect thereto as in effect at the time of filing.  Such financial statements have been prepared in accordance with United States generally accepted accounting principles applied on a consistent basis during the periods involved (“GAAP”),
      except as may be otherwise specified in such financial statements or the notes thereto and except that unaudited financial statements may not contain all footnotes required by GAAP, and fairly present in all material respects the financial position
      of the Company as of and for the dates thereof and the results of operations and cash flows for the periods then ended, subject, in the case of unaudited statements, to normal, immaterial, year-end audit adjustments.  Except as set forth in the SEC
      Documents, the Company has received no notices or correspondence from the SEC for the one year preceding the date hereof.  To the Company’s knowledge, the SEC has not commenced any enforcement proceedings
      against the Company.

    

    

    (g)          Absence of Certain Changes.  Except as disclosed in the SEC Documents, since December 31, 2020, there has been no material adverse change in the business, properties, operations,
      financial condition or results of operations of the Company or its Subsidiaries.  The Company has not taken any steps, and does not currently expect to take any steps, to seek protection pursuant to any Bankruptcy Law nor does the Company or any of
      its Subsidiaries have any knowledge or reason to believe that its creditors intend to initiate involuntary bankruptcy or insolvency proceedings. The Company is financially solvent and is generally able to pay
      its debts as they become due.

    

    

    (h)          Absence of Litigation. There is no action, suit, proceeding, inquiry or investigation before or by any court, public board, government agency, self-regulatory organization or body
      pending or, to the knowledge of the Company or any of its Subsidiaries, threatened against or affecting the Company, the Common Stock or any of the Company’s or its Subsidiaries’ officers or directors in their capacities as such, which could
      reasonably be expected to have a Material Adverse Effect.

    

    

    (i)          Acknowledgment Regarding Investors’ Status.  The Company acknowledges and agrees that each of the Investors are acting solely in the capacity of an arm’s length purchaser with
      respect to the Transaction Documents and the transactions contemplated hereby and thereby.  The Company further acknowledges that none of the Investors are acting as a financial advisor or fiduciary of the Company (or in any similar capacity) with
      respect to the Transaction Documents and the transactions contemplated hereby and thereby and any advice given by any of the Investors or any of their respective representatives or agents in connection with the Transaction Documents and the
      transactions contemplated hereby and thereby is merely incidental to such Investor’s purchase of the Securities.  The Company further represents to each of the Investors that the Company’s decision to enter into the Transaction Documents has been
      based solely on the independent evaluation by the Company and its representatives and advisors.

    

    

    (j)          No Integrated Offering.  Neither the Company, nor or any of its affiliates, nor any Person acting on their behalf has, directly or indirectly, made any offers or sales of any
      security or solicited any offers to buy any security, under circumstances that would cause this offering of the Securities to be integrated with prior offerings by the Company in a manner that would require stockholder approval pursuant to the rules
      of the Principal Market on which any of the securities of the Company are listed or designated. The issuance and sale of the Purchase Shares and Warrants hereunder does not contravene the rules and regulations of the Principal Market.

      unpatentable proprietary or Confidential Information, systems or procedures) (collectively, the “Intellectual Property”), necessary for the conduct of their respective businesses as conducted as of the date hereof, except to the extent that
      the failure to own or possess adequate rights to use such Intellectual Property would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. The Company and the Subsidiaries have not received any written
      notice of any claim of infringement or conflict which asserted Intellectual Property rights of others, which infringement or conflict, if the subject of an unfavorable decision, would reasonably be expected to result in a Material Adverse Effect.
      There are no pending, or to the Company’s knowledge, threatened judicial proceedings or interference proceedings challenging the Company’s or any Subsidiary’s rights in or to or the validity of the scope of any of the Company’s or its Subsidiaries’
      patents, patent applications or proprietary information. To the Company’s knowledge, no other entity or individual has any right or claim in any of the Company’s or any of its Subsidiary’s patents, patent applications or any patent to be issued
      therefrom by virtue of any contract, license or other agreement entered into between such entity or individual and the Company or any Subsidiary or by any non-contractual obligation, other than by written licenses granted by the Company or any
      Subsidiary, except as would not, individually or in the aggregate, have a Material Adverse Effect. The Company has not received any written notice of any claim challenging the rights of the Company or its Subsidiaries in or to any Intellectual
      Property owned, licensed or optioned by the Company or any Subsidiary which claim, if the subject of an unfavorable decision, would reasonably be expected to result in a Material Adverse Effect.

    

    

    (l)          Environmental Laws.  The Company and its Subsidiaries (i) are in compliance with any and all applicable foreign, federal, state and local laws and regulations relating to the
      protection of human health and safety, the environment or hazardous or toxic substances or wastes, pollutants or contaminants (“Environmental Laws”), (ii) have received all permits, licenses or other approvals required of them under applicable
      Environmental Laws to conduct their respective businesses and (iii) are in compliance with all terms and conditions of any such permit, license or approval, except where, in each of the three foregoing clauses, the failure to so comply could not
      reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect.

    

    

    (m)          Title.  Except as set forth in the SEC Documents, the Company and its Subsidiaries have good and marketable title in fee simple to all real property owned by them and good and
      marketable title in all personal property owned by them that is material to the business of the Company and its Subsidiaries, in each case free and clear of all liens, encumbrances and defects (“Liens”) and, except for Liens as do not
      materially affect the value of such property and do not materially interfere with the use made and proposed to be made of such property by the Company and its Subsidiaries and Liens for the payment of federal, state or other taxes, the payment of
      which is neither delinquent nor subject to penalties.  Any real property and facilities held under lease by the Company and its Subsidiaries are held by them under valid, subsisting and enforceable leases with which the Company and its Subsidiaries
      are in compliance with such exceptions as are not material and do not interfere with the use made and proposed to be made of such property and buildings by the Company and its Subsidiaries.

    

    

    (n)          Insurance.  The Company and each of its Subsidiaries are insured by insurers of recognized financial responsibility against such losses and risks and in such amounts as management
      of the Company believes to be prudent and customary in the businesses in which the Company and its Subsidiaries are engaged.  Neither the Company nor any such Subsidiary has been refused any insurance coverage sought or applied for and neither the
      Company nor any such Subsidiary has any reason to believe that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its
      business at a cost that would not materially and adversely affect the condition, financial or otherwise, or the earnings, business or operations of the Company and its Subsidiaries, taken as a whole.

      issued by, and have made all declarations and filings with, the appropriate federal, state, local or foreign governmental or regulatory authorities that are necessary for the ownership or lease of their respective properties or the conduct of their
      respective businesses as currently conducted, as described in the Registration Statement and the Prospectus (the “Permits”). Neither the Company nor any Subsidiary has received written notice of any proceeding relating to revocation or
      modification of any such Permit or has any reason to believe that such Permit will not be renewed in the ordinary course, except where the failure to obtain any such renewal would not, individually or in the aggregate, reasonably be expected to have
      a Material Adverse Effect.

    

    

    (p)          Tax Status.  Except for matters that would not, individually or in the aggregate, have or reasonably be expected to result in a Material Adverse Effect, the Company and each of
      its Subsidiaries has made or filed all federal and state income and all other material tax returns, reports and declarations required by any jurisdiction to which it is subject (unless and only to the extent that the Company and each of its
      Subsidiaries has set aside on its books provisions reasonably adequate for the payment of all unpaid and unreported taxes) and has paid all taxes and other governmental assessments and charges that are material in amount, shown or determined to be
      due on such returns, reports and declarations, except those being contested in good faith and has set aside on its books provision reasonably adequate for the payment of all taxes for periods subsequent to the periods to which such returns, reports
      or declarations apply.  There are no unpaid taxes in any material amount claimed to be due by the taxing authority of any jurisdiction, and the officers of the Company know of no basis for any such claim.

      inapplicable any control share acquisition, business combination, poison pill (including any distribution under a rights agreement) or other similar anti-takeover provision under the Certificate of Incorporation or the laws of the state of its
      incorporation which is or could become applicable to any of the Investors as a result of the transactions contemplated by this Agreement, including, without limitation, the Company’s issuance of the Purchase Shares and Warrants and the Investors’
      ownership of the Securities.

      Agreement, is true and correct and does not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements made therein, in light of the circumstances under which they were made, not
      misleading. The press releases disseminated by the Company during the twelve months preceding the date of this Agreement taken as a whole do not contain any untrue statement of a material fact or omit to state a material fact required to be stated

    (u)          Registration Statement.  The Company has prepared and filed with the SEC in accordance with the provisions of the Securities Act the Registration Statement. The Registration
      Statement was declared effective by order of the SEC on February 12, 2021. The Registration Statement is effective pursuant to the Securities Act and available for the issuance of the Securities thereunder, and the Company has not received any
      written notice that the SEC has issued or intends to issue a stop order or other similar order with respect to the Registration Statement or the Prospectus or that the SEC otherwise has (i) suspended or withdrawn the effectiveness of the Registration
      Statement or (ii) issued any order preventing or suspending the use of the Prospectus or any Prospectus Supplement, in either case, either temporarily or permanently or intends or has threatened in writing to do so. The “Plan of Distribution” section
      of the Prospectus permits the issuance and sale of the Purchase Shares and the Warrants under the terms of this Agreement, and the Warrant Shares upon exercise of the Warrants. At the time the Registration Statement and any amendments thereto became
      effective, at the date of this Agreement and at each deemed effective date thereof pursuant to Rule 430B(f)(2) of the Securities Act, the Registration Statement and any amendments thereto complied and will comply in all material respects with the
      requirements of the Securities Act and did not and will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading; and the Base
      Prospectus and any Prospectus Supplement thereto, at the time such Base Prospectus or such Prospectus Supplement thereto was issued and on the Closing Date, complied and will comply in all material respects with the requirements of the Securities Act
      and did not and will not contain an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading; provided that this

      Investor expressly for use therein. The Company meets all of the requirements for the use of a registration statement on Form S-3 pursuant to the Securities Act for the offering and sale of the Securities contemplated by this Agreement and the
      Warrants in reliance on General Instruction I.B.1. of Form S-3, and the SEC has not notified the Company of any objection to the use of the form of the Registration Statement pursuant to Rule 401(g)(1) of the Securities Act. The Company hereby
      confirms that the issuance of the Purchase Shares and the Warrants to the Investors pursuant to this Agreement do not, and the issuance of the Warrant Shares upon exercise of the Warrants would not result in non-compliance with the Securities Act or
      any of the General Instructions to Form S-3. The Registration Statement, as of its effective date, meets the requirements set forth in Rule 415(a)(1)(x) pursuant to the Securities Act. At the earliest time after the filing of the Registration

      405 of the Securities Act).  The Company has not distributed any offering material in connection with the offering and sale of any of the Securities, and, until none of the Investors hold any of the Purchase Shares or Warrants, shall not distribute
      any offering material in connection with the offering and sale of any of the Securities, to or by any of the Investors, in each case, other than the Registration Statement or any amendment thereto, the Prospectus or any Prospectus Supplement required
      pursuant to applicable law or the Transaction Documents. The Company has not made, and agrees that unless it obtains the prior written consent of each of the Investors it will not make, an offer relating to the Securities that would constitute a
      “free writing prospectus” as defined in Rule 405 under the Securities Act. The Company shall comply with the requirements of Rules 164 and 433 under the Securities Act applicable to any such free writing prospectus consented to by each of the
      Investors, including in respect of timely filing with the SEC, legending and record keeping.

      similar rules, regulations or guidelines, issued, administered or enforced by any governmental agency having jurisdiction over the Company (collectively, the “Money Laundering Laws”), except where the failure to be in such compliance would not
      reasonably be expected to result in a Material Adverse Effect; and no action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving the Company or any Subsidiary with respect to the Money

    (gg)          Labor Relations. No labor dispute exists or, to the knowledge of the Company, is imminent with respect to any of the employees of the Company, which could reasonably be expected

      is a party to a collective bargaining agreement, and the Company and its Subsidiaries believe that their relationships with their employees are good. To the knowledge of the Company, no executive officer of the Company or any Subsidiary, is, or is
      now expected to be, in violation of any material term of any employment contract, confidentiality, disclosure or proprietary information agreement or non-competition agreement, or any other contract or agreement or any restrictive covenant in favor
      of any third party, and the continued employment of each such executive officer does not subject the Company or any of its Subsidiaries to any liability with respect to any of the foregoing matters. The Company and its Subsidiaries are in compliance
      with all U.S. federal, state, local and foreign laws and regulations relating to employment and employment practices, terms and conditions of employment and wages and hours, except where the failure to be in compliance could not, individually or in

      Subsidiary.

      regulations thereunder (“FDCA”) that is manufactured, packaged, labeled, tested, distributed, sold, and/or marketed by the Company or any of its Subsidiaries (each such product, a “Pharmaceutical Product”), such Pharmaceutical Product
      is being manufactured, packaged, labeled, tested, distributed, sold and/or marketed by the Company in compliance with all applicable requirements under FDCA and similar laws, rules and regulations relating to registration, investigational use,
      premarket clearance, licensure, or application approval, good manufacturing practices, good laboratory practices, good clinical practices, product listing, quotas, labeling, advertising, record keeping and filing of reports, except where the failure
      to be in compliance would not have a Material Adverse Effect. There is no pending, completed or, to the Company’s knowledge, threatened, action (including any lawsuit, arbitration, or legal or administrative or regulatory proceeding, charge,
      complaint, or investigation) against the Company or any of its Subsidiaries, and none of the Company or any of its Subsidiaries has received any notice, warning letter or other communication from the FDA or any other governmental entity, which (i)
      contests the premarket clearance, licensure, registration, or approval of, the uses of, the distribution of, the manufacturing or packaging of, the testing of, the sale of, or the labeling and promotion of any Pharmaceutical Product, (ii) withdraws
      its approval of, requests the recall, suspension, or seizure of, or withdraws or orders the withdrawal of advertising or sales promotional materials relating to, any Pharmaceutical Product, (iii) imposes a clinical hold on any clinical investigation

      the Company have been and are being conducted in all material respects in accordance with all applicable laws, rules and regulations of the FDA. The Company has not been informed by the FDA that the FDA will prohibit the marketing, sale, license or
      use in the United States of any product proposed to be developed, produced or marketed by the Company nor has the FDA expressed any concern as to approving or clearing for marketing any product being developed or proposed to be developed by the

    5.          COVENANTS.

    

    

    (a)          Filing of Press Release and Initial Prospectus Supplement.  The Company agrees that it shall, (i) prior to 9:30 a.m., New York City Time, on June 4, 2021, issue a press release
      relating to the transactions contemplated by, and describing the material terms and conditions of, the Transaction Documents (the “Press Release”) and (ii) file a Current Report on Form 8-K (the “Current Report”), including the Transaction
      Documents as exhibits thereto, with the SEC prior to 5:30 p.m., New York City Time, on June 4, 2021. The Company further agrees that it shall, within the time required under Rule 424(b) under the Securities Act, file with the SEC the Initial
      Prospectus Supplement pursuant to Rule 424(b)(5) under the Securities Act, which Initial Prospectus Supplement shall specifically relate to the Securities and shall describe the material terms and conditions of the Transaction Documents, contain
      information previously omitted at the time of effectiveness of the Registration Statement in reliance on Rule 430B under the Securities Act, and disclose all information relating to the Securities and the transactions contemplated by the Transaction
      Documents required to be disclosed in the Registration Statement and the Prospectus as of the date of the Initial Prospectus Supplement, including, without limitation, information required to be disclosed in the section captioned “Plan of
      Distribution” in the Prospectus. From and after the issuance of the Press Release, the Company represents to the Investors that it shall have publicly disclosed all material, non-public information delivered to any of the Investors by the Company or
      any of its Subsidiaries, or any of their respective officers, directors, employees or agents in connection with the transactions contemplated by the Transaction Documents. In addition, effective upon the issuance of the Press Release with the SEC,
      the Company acknowledges and agrees that any and all confidentiality or similar obligations under any agreement, whether written or oral, between the Company, any of its Subsidiaries or any of their respective officers, directors, agents, employees
      or Affiliates on the one hand, and any of the Investors or any of their Affiliates on the other hand, shall terminate. The Company shall provide each Investor with an opportunity to review and comment upon the final draft version of the Press Release
      and the final pre-filing draft versions of the Current Report and the Initial Prospectus Supplement within a reasonable time prior to their issuance and filing with the SEC, as applicable, and the Company shall give reasonable consideration to all
      such comments. Each Investor shall use its reasonable best efforts to comment upon the final pre-filing draft versions of the Current Report and the Initial Prospectus Supplement within a reasonable time after such Investor receives them from the
      Company. Each Investor shall furnish to the Company such information regarding itself, the Securities beneficially owned by it and the intended method of distribution thereof, including any arrangement between such Investor and any other Person
      relating to the sale or distribution of the Securities, as shall be reasonably requested by the Company in connection with the preparation and filing of the Current Report and the Initial Prospectus Supplement, and shall otherwise cooperate with the
      Company as reasonably requested by the Company in connection with the preparation and filing of the Current Report and the Initial Prospectus Supplement with the SEC. Notwithstanding the foregoing, the Company shall not publicly disclose the name of
      any Investor, or include the name of any Investor in any filing with the SEC or any regulatory agency or the Principal Market, without the prior written consent of such Investor, except: (i) as required by federal securities law in connection with
      the filing of final Transaction Documents with the SEC and (ii) to the extent such disclosure is required by law or Principal Market regulations, in which case the Company shall provide the Investors with prior notice of such disclosure permitted
      under this clause (ii).

    

    

    (b)          Blue Sky. The Company shall take all such action, if any, as is reasonably necessary in order to obtain an exemption for or to register or qualify (i) the offer and sale of the
      Securities to the Investors under this Agreement and (ii) any subsequent resale of all Securities by the Investors, in each case, under applicable securities or “Blue Sky” laws of the states of the United States in such states as is reasonably
      requested by any of the Investors from time to time, and shall provide evidence of any such action so taken to each of the Investors.

    
      -17-

      
        


    

    

    

    (c)          Listing/DTC.  The Company shall promptly secure the listing of all of the Purchase Shares to be issued to the Investor hereunder and all of the Warrant Shares issuable upon
      exercise of the Warrants on the Principal Market (subject to official notice of issuance) and upon each other national securities exchange or automated quotation system, if any, upon which the Common Stock is then listed, and shall use commercially
      reasonable efforts to maintain, so long as any shares of Common Stock shall be so listed, such listing of all such Purchase Shares and Warrant Shares. The Company shall use commercially reasonable efforts to maintain the listing of the Common Stock
      on the Principal Market and shall comply in all respects with the Company’s reporting, filing and other obligations under the bylaws or rules and regulations of the Principal Market. Neither the Company nor any of its Subsidiaries shall take any
      action that would reasonably be expected to result in the delisting or suspension of the Common Stock on the Principal Market.  The Company shall pay all fees and expenses in connection with satisfying its obligations under this Section 5(c).  The
      Company shall take all action necessary to ensure that its Common Stock can be transferred electronically as DVP Shares.

    

    

    (d)          Short Sales and Hedging Transactions.  Each Investor covenants and agrees that neither it, nor any of its respective agents, representatives or Affiliates, shall, at any time
      beginning on the date of this Agreement and ending when such Investor no longer holds any Warrants, enter into or effect in any manner whatsoever, directly or indirectly, any (i) “short sale” (as such term is defined in Rule 200 of Regulation SHO of
      the Exchange Act) of the Common Stock or (ii) hedging transaction, which establishes a net short position with respect to the Common Stock.

    

    

    (e)          Reservation of Shares.  So long as any portion of any of the Warrants remains outstanding, the Company shall take all action necessary to at all times have authorized, and
      reserved for the purpose of issuance, no less than 100% of the sum of the maximum number of Warrant Shares issuable upon exercise in full of the Warrants (without regard to any limitations on the exercise of the Warrants set forth therein)
      (collectively, the “Required Reserve Amount”); provided that at no time shall the number of shares of Common Stock reserved pursuant to this Section 5(e) be reduced other than proportionally in connection with any exercise of the Warrants. If
      at any time the number of shares of Common Stock authorized and reserved for issuance is not sufficient to meet the Required Reserve Amount, the Company will promptly take all corporate action necessary to authorize and reserve a sufficient number of
      shares, including, without limitation, calling a special meeting of stockholders to authorize additional shares to meet the Company’s obligations pursuant to the Transaction Documents, in the case of an insufficient number of authorized shares,
      obtain stockholder approval of an increase in such authorized number of shares, and voting the management shares of the Company in favor of an increase in the authorized shares of the Company to ensure that the number of authorized shares is
      sufficient to meet the Required Reserve Amount.

    

    

    (f)          Non-Public Information.  Except with respect to the material terms and conditions of the transactions contemplated by the Transaction Documents that will be timely publicly
      disclosed by the Company pursuant to Section 5(a) hereof, the Company confirms that neither it nor any other Person acting on its behalf shall provide any of the Investors or its agents or counsel with any information that constitutes or might
      constitute material, non-public information, unless a simultaneous public announcement thereof is made by the Company in the manner contemplated by Regulation FD. In the event of a breach of the foregoing covenant by the Company or any Person acting
      on its behalf (as determined in the reasonable good faith judgment of any Investor), in addition to any other remedy provided herein or in the other Transaction Documents, if such Investor is holding any Securities at the time of the disclosure of
      material, non-public information, such Investor shall have the right to make a public disclosure, in the form of a press release, public advertisement or otherwise, of such material, non-public information without the prior approval by the Company;
      provided such Investor shall have first provided notice to the Company that it believes it has received information that constitutes material, non-public information, the Company shall have at least 24 hours to publicly disclose such material,
      non-public information prior to any such disclosure by such Investor, the Company shall have failed to demonstrate to such Investor in writing within such time period that such information does not constitute material, non-public information, and the
      Company shall have failed to publicly disclose such material, non-public information within such time period. None of the Investors shall have any liability to the Company, any of its Subsidiaries, or any of their respective directors, officers,
      employees, stockholders or agents, for any such disclosure. The Company understands and confirms that each of the Investors shall be relying on the foregoing covenants in effecting transactions in securities of the Company.

    (g)          Subsequent Equity Issuances. From and after the date of this Agreement until thirty days following the Closing Date (the “Initial Restricted Period”), without the consent
      of the Investors which purchased at least 50.1% in interest of the Purchase Shares and corresponding Warrants, including the Lead Investor (the “Required Investors”), and from and after thirty one days following the Closing Date until sixty
      (60) days following the Closing Date (together with the Initial Restricted Period, the “Restricted Period”), without the prior written consent of the Investor identified as the “Lead Investor” on Schedule I hereto (the “Lead

      Stock Equivalents (or a combination of units thereof), other than in connection with an Exempt Issuance. Each of the Investors shall be entitled to seek injunctive relief against the Company and its Subsidiaries to preclude any such issuance, which
      remedy shall be in addition to any right to collect damages, without the necessity of showing economic loss and without any bond or other security being required. “Common Stock Equivalents” means any securities of the Company or its
      Subsidiaries which entitle the holder thereof to acquire at any time Common Stock, including, without limitation, any debt, preferred stock, rights, options, warrants or other instrument that is at any time convertible into or exercisable or

      that adversely affects any other Investor, or upon the exercise, exchange or conversion of any shares of Common Stock, Common Stock Equivalents or other securities issued and outstanding on the date of this Agreement and held by any of the Investors,
      provided that during the Restricted Period, the exercise or conversion price of any such security is not lowered, none of the terms of such securities are amended to increase the number of shares issuable thereunder and none of the terms or
      conditions of any such securities are otherwise materially changed in any manner that adversely affects any other Investor, (iii)  the issuances of equity-based awards pursuant to an Approved Stock Plan (as defined below), and the issuances of shares

      the number of shares issuable thereunder and none of the terms or conditions of any such equity-based award are otherwise materially changed in any manner that adversely affects any of the Investors, (iv) shares of Common Stock issued upon the

      exercise or other method of issuance (as the case may be) of any such Common Stock Equivalent is made solely pursuant to the conversion, exercise or other method of issuance (as the case may be) provisions of such Common Stock Equivalent that were in

      thereunder and none of the terms or conditions of any such Common Stock Equivalents (other than standard options to purchase Common Stock issued pursuant to an Approved Stock Plan that are covered by clause (iii) above) are otherwise materially
      changed in any manner that adversely affects any of the Investors, or (v) shares of Common Stock in an “at- the-market offering” (as defined in Rule 415(a)(4) under the Securities Act) through one or more registered broker-dealer(s), pursuant to an
      agreement between the Company and such registered broker-dealer(s), at a price per share of Common Stock equal to or greater than $7.3118 (representing 150% of the Per Unit Purchase Price), subject to adjustment for any stock splits, reverse stock
      splits, stock dividends and similar events after the date of this Agreement (such sales of Common Stock referred to in this clause (vi), “Exempt ATM Sales”). “Approved Stock Plan” means any employee benefit plan which has been approved

    (i)          Securities Law Compliance. For so long as any Investor holds any Securities, the Company shall take all action necessary to cause the Common Stock to continue to be registered as
      a class of securities under Sections 12(g) or 12(b) of the Exchange Act, shall comply with its reporting and filing obligations under the Exchange Act, and shall not take any action or file any document (whether or not permitted by the Exchange Act)
      to terminate or suspend such registration or to terminate or suspend its reporting and filing obligations under the Exchange Act. If all or any portion of a Warrant is exercised at a time when there is an effective registration statement to cover the
      issuance or resale of the Warrant Shares or if the Warrant is exercised via cashless exercise, the Warrant Shares issued pursuant to any such exercise shall be issued free of all legends.  If at any time following the date hereof the Registration
      Statement (or any subsequent registration statement registering the sale or resale of the Warrant Shares) is not effective or is not otherwise available for the sale or resale of the Warrant Shares, the Company shall immediately notify the holders of
      the Warrants in writing that such registration statement is not then effective and thereafter shall promptly notify such holders when the registration statement is effective again and available for the sale or resale of the Warrant Shares (it being
      understood and agreed that the foregoing shall not limit the ability of the Company to issue, or any Investor to sell, any of the Warrant Shares in compliance with applicable federal and state securities laws).  The Company shall use best efforts to
      keep a registration statement (including the Registration Statement) registering the issuance or resale of the Warrant Shares effective from and after the date hereof until the earlier of (i) such time that none of the Investors or any of their
      Affiliates beneficially owns any portion of any of the Warrants and (ii) the expiration of the Warrants in accordance with the terms of the Warrants. Each Investor shall furnish to the Company such information regarding itself, its affiliates, the
      Securities beneficially owned by it and the intended method of distribution thereof as shall be reasonably requested by the Company in connection with the preparation and filing of any such amendment to the Registration Statement or any such
      Prospectus Supplement, and shall otherwise cooperate with the Company as reasonably requested by the Company in connection with the preparation and filing of any such registration statement or any amendment or supplement to the Registration Statement
      in connection with the performance by the Company of its obligations hereunder. The Company shall comply with all applicable federal, state and foreign securities laws in connection with the offer, issuance and sale by the Company of the Securities
      contemplated by the Transaction Documents. Without limiting the generality of the foregoing, neither the Company nor any of its officers, directors or affiliates will take, directly or indirectly, any action designed or intended to stabilize or
      manipulate the price of any security of the Company, or which would reasonably be expected to cause or result in, stabilization or manipulation of the price of any security of the Company.

    

    

    (j)          Integration. From and after the date of this Agreement, neither the Company, nor any of its affiliates will, and the Company shall use its reasonable best efforts to ensure that
      no Person acting on any of their behalf will, directly or indirectly, make any offers or sales of any security or solicit any offers to buy any security, under circumstances that would cause this offering of the Securities to be integrated with other
      offerings of securities by the Company in a manner that would require stockholder approval pursuant to the rules and regulations of the Principal Market on which any of the securities of the Company are listed or designated, unless stockholder
      approval is obtained before the closing of such subsequent transaction in accordance with the rules of such Principal Market.

    

    

    (k)          Use of Proceeds. The Company will use the net proceeds from the offering of the Purchase Shares and the Warrants as described in the Prospectus.

    (l)          Variable Rate Transactions. From and after the date of this Agreement until the third (3rd)
      anniversary of the Closing Date, without the prior written consent of the Lead Investor (which may be granted or withheld in its sole discretion), the Company shall be prohibited from effecting or entering into an agreement to effect any issuance by
      the Company or any of its Subsidiaries of Common Stock or Common Stock Equivalents (or a combination of units thereof) involving a Variable Rate Transaction. “Variable Rate Transaction” means a transaction in which the Company (A) issues or
      sells any debt or equity securities that are convertible into, exchangeable or exercisable for, or include the right to receive additional shares of Common Stock either (1) at a conversion price, exercise price or exchange rate or other price that is
      based upon and/or varies with the trading prices of or quotations for the shares of Common Stock at any time after the initial issuance of such debt or equity securities, or (2) with a conversion, exercise or exchange price that is subject to being
      reset at some future date after the initial issuance of such debt or equity security or upon the occurrence of specified or contingent events directly or indirectly related to the business of the Company or the market for the Common Stock or (B)
      enters into any agreement (including, without limitation, an “equity line of credit”) with any Person, other than with the Lead Investor, whereby the Company or any Subsidiary may sell securities at a future determined price. Notwithstanding the
      foregoing, beginning on the Business Day immediately following the last day of the Restricted Period (and in no event during the Restricted Period), the Company may sell shares of Common Stock in an “at- the-market offering” (as defined in Rule
      415(a)(4) under the Securities Act) through one or more registered broker-dealer(s), pursuant to an agreement between the Company and such registered broker-dealer(s), irrespective of whether such sales are Exempt ATM Sales. Each of the Investors
      shall be entitled to seek injunctive relief against the Company and its Subsidiaries to preclude any such agreement, plan, arrangement or transaction, which remedy shall be in addition to any right to collect damages, without the necessity of showing
      economic loss and without any bond or other security being required.

    

    

    (m)          Participation Right. From and after the date of this Agreement until the first (1st) anniversary of the Closing Date, and except as set forth in clause (x) of this Section 5(m),
      the Company shall be prohibited from effecting or entering into an agreement to effect any issuance by the Company or any of its Subsidiaries of Common Stock or Common Stock Equivalents (or a combination of units thereof) for cash consideration (a “Subsequent





        Financing”), unless the Company shall have first complied with this Section 5(m). The Company acknowledges and agrees that the right set forth in this Section 5(m) is a right granted by the Company, separately, to each Investor.

    

    

    (i)            Between 4:00 p.m. and 7:00 p.m., New York time, on the second (2nd) Business Day
      immediately preceding the Business Day of a proposed or intended Subsequent Financing (each, a “Subsequent Financing Date”), the Company shall deliver to each Investor a written notice of its intention to effect a Subsequent Financing (each, a
      “Pre-Notice”) (the Company shall use best efforts to ensure that each Investor has received and acknowledged receipt of the Pre-Notice within such time period), which Pre-Notice shall not contain any information (including, without limitation,
      material, non-public information) other than: (x) a statement that the Company proposes or intends to effect a Subsequent Financing (without disclosing the specific terms or conditions of the proposed Subsequent Financing or the securities to be
      offered and sold therein), (y) a representation that such statement (described in clause (x) above) does not constitute material, non-public information regarding the Company, its business or its securities and (z) a statement informing such Investor
      that it is entitled to receive a Subsequent Financing Notice (as defined below) containing material, non-public information with respect to such Subsequent Financing upon its timely written request in accordance with this Section 5(m).

    
      -21-

      
        


    

    

    

    (ii)           If such Investor consents to receive material, non-public information with respect to such Subsequent Financing, such Investor shall deliver a written request
      therefor to the Company, not later than 9:00 a.m., New York time, on the Business Day immediately preceding the Business Day of the proposed or intended Subsequent Financing, and upon such written request by such Investor delivered to the Company
      prior to such time, and only upon such written request by such Investor, the Company shall promptly thereafter, but not later than two (2) hours after such written request by such Investor was properly delivered to the Company, deliver to such
      Investor a written notice of the proposed Subsequent Financing (a “Subsequent Financing Notice”), which shall (A) describe in reasonable detail the proposed terms and conditions of such Subsequent Financing, including, without limitation, the
      proposed terms of the securities to be offered and sold in such Subsequent Financing (the “Offered Securities”), the total amount of proceeds intended to be raised and the Person or Persons through or with whom such Subsequent Financing is
      proposed to be effected, (B) include, as an attachment thereto, a term sheet or similar document setting forth the material terms and conditions of such Subsequent Financing, including, without limitation, the material terms of the Offered
      Securities, and (C) offer to issue and sell to such Investor, upon the terms and subject to the conditions of the Subsequent Financing set forth in the Subsequent Financing Notice, at the same price per Offered Security to be paid by each other
      Person participating in such Subsequent Financing, such Investor’s pro rata portion of 50% of the Offered Securities (such 50% of Offered Securities in the aggregate, the “Maximum Investor Participation Amount”), provided that the number of
      Offered Securities which such Investor shall have the right to subscribe for under this Section 5(m) shall be (x) based on such Investor’s pro rata portion of the aggregate number of Purchase Shares purchased hereunder by all Investors on the Closing
      Date (the “Basic Amount”), and (y) with respect to the Lead Investor only, if the Lead Investor shall elect to purchase its full Basic Amount hereunder, any additional portion of the Offered Securities attributable to the Basic Amounts of
      other Investors as the Lead Investor shall indicate it will purchase or acquire should any one or more of the other Investors subscribe for less than their respective Basic Amounts (such undersubscribed Basic Amounts, in the aggregate, the “Undersubscription





        Amount”).

    

    

    (iii)          In the event that such Investor elects to participate in such Subsequent Financing for all or any part of such Investor’s Basic Amount, such Investor must deliver a
      written notice to the Company prior to the later of (i) 11:00 a.m., New York time, on the Business Day on which such proposed or intended Subsequent Financing shall occur as set forth in the Subsequent Financing Notice and (ii) two (2) hours after
      the time that the applicable Subsequent Financing Notice is received by such Investor (the “Notice Termination Time”), setting forth: (A) a statement that such Investor elects to participate in such Subsequent Financing, (B) (1) the portion of
      such Investor’s Basic Amount that such Investor elects to purchase in such Subsequent Financing, and, (2) with respect to the Lead Investor only, if the Lead Investor shall elect to purchase all of the Lead Investor’s Basic Amount, the portion of the
      Undersubscription Amount, if any, that the Lead Investor shall elect to purchase in addition to the Lead Investor’s Basic Amount, and (C) a representation that such Investor has sufficient funds available to purchase such Basic Amount (and with
      respect to the Lead Investor only, such Undersubscription Amount in addition to such Basic Amount) in such Subsequent Financing on the terms and subject to the conditions set forth in the applicable Subsequent Financing Notice received by such
      Investor (the “Notice of Acceptance”). If the Company does not receive a Notice of Acceptance from an Investor prior to the applicable Notice Termination Time, such Investor shall be deemed to have elected not to participate in the Subsequent
      Financing on the terms set forth in the applicable Subsequent Financing Notice received by such Investor.

    
      -22-

      
        


    

    

    

    (iv)          Notwithstanding the foregoing, if the Company desires to change, modify or amend any of the terms or conditions of a Subsequent Financing, or the Offered Securities
      to be sold therein, set forth in a Subsequent Financing Notice delivered to the Investors hereunder, the Company shall promptly, but not later than 10:00 p.m., New York time, on the Business Day immediately preceding the Business Day on which such
      Subsequent Financing is intended to occur, deliver to each Investor a new written Subsequent Financing Notice describing in reasonable detail the terms and conditions of such Subsequent Financing and Offered Securities, as amended, and each Investor
      will again have the right to participate in such Subsequent Financing upon the terms and conditions, as amended, set forth in such new Subsequent Financing Notice, provided such Investor delivers to the Company a Notice of Acceptance providing the
      information described in the penultimate sentence of Section 5(m)(iii) above, prior to the Notice Termination Time with respect to such new Subsequent Financing Notice, which shall be the later of (I) 11:00 a.m., New York time, on the Business Day on
      which such proposed Subsequent Financing providing for such amended terms and conditions as set forth in the new Subsequent Financing Notice delivered to such Investor hereunder is intended to occur and (II) two (2) hours after the time that such new
      Subsequent Financing Notice was received by such Investor. If by the Notice Termination Time, an Investor has delivered to the Company a Notice of Acceptance in which it has elected to purchase in such Subsequent Financing an aggregate amount of
      Offered Securities that is greater than such Investor’s Basic Amount, such Investor shall be deemed to have elected to participate for such Investor’s applicable Basic Amount in the Subsequent Financing on the terms set forth in the applicable
      Subsequent Financing Notice received by such Investor.

    

    

    (v)           If by the Notice Termination Time, the Investors, in the aggregate, have elected to purchase in such Subsequent Financing an aggregate amount of Offered Securities
      that is equal to or less than the Maximum Investor Participation Amount, or none of the Investors has elected to participate in such Subsequent Financing, then the Company may (A) offer, issue and sell all or any part of an Investor’s Basic Amount as
      to which a Notice of Acceptance has not been given by such Investor (or by the Lead Investor as part of the Undersubscription Amount that the Lead Investor has elected to purchase pursuant to the Lead Investor’s Notice of Acceptance) (all such
      Offered Securities included in the Maximum Investor Participation Amount that are not designated in a Notice of Acceptance as Offered Securities to be purchased by Investors in such Subsequent Financing, the “Other Securities”), pursuant to a
      definitive agreement(s) (the “Subsequent Financing Agreement”), but only to the offerees described in the Subsequent Financing Notice and only upon terms and conditions (including, without limitation, unit prices and interest rates) that are
      not more favorable to the acquiring Person or Persons or less favorable to the Company than those set forth in the most recent Subsequent Financing Notice received by the Investors and (B) to publicly announce (x) the execution of such Subsequent
      Financing Agreement, and (y) either (I) the consummation of the transactions contemplated by such Subsequent Financing Agreement or (II) the termination of such Subsequent Financing Agreement, which shall be filed with the SEC on a Current Report on
      Form 8-K with such Subsequent Financing Agreement and any documents contemplated therein filed as exhibits thereto. If a definitive agreement containing the terms and conditions of such Subsequent Financing as set forth in the Subsequent Financing
      Notice delivered to the Investors is not entered into by the Company for any reason within five (5) Business Days after the date the initial Subsequent Financing Notice for such Subsequent Financing was first delivered to the Investors hereunder, and
      to the extent that the Company determines to proceed with such Subsequent Financing, the Company shall promptly, but not later than 10:00 p.m., New York time, on the Business Day immediately preceding the Business Day on which such Subsequent
      Financing is intended to occur, deliver to each of the Investor a new written Subsequent Financing Notice describing in reasonable detail the terms and conditions of such Subsequent Financing and Offered Securities, as amended, and each of the
      Investors will again have the right to participate in such Subsequent Financing upon the terms and conditions, as amended, set forth in such new Subsequent Financing Notice, provided such Investor delivers to the Company a Notice of Acceptance
      providing the information described in the penultimate sentence of Section 5(m)(iii) above, prior to the Notice Termination Time with respect to such new Subsequent Financing Notice, which shall be the time period described in Section 5(m)(iv) above.

    
      -23-

      
        


    

    

    

    (vi)          In the event the Company shall propose to sell less than all the Other Securities (any such sale to be in the manner and on the terms specified in Section 5(m)(v)
      above), then each Investor may, at its sole option and in its sole discretion, reduce the number or amount of the Offered Securities specified in its Notice of Acceptance to an amount that shall be not less than the number or amount of the Offered
      Securities that such Investor elected to purchase pursuant to Section 5(m)(iii) above multiplied by a fraction, (A) the numerator of which shall be the number or amount of Offered Securities the Company actually proposes to issue, sell or exchange
      (including Offered Securities to be issued or sold to such Investor pursuant to this Section 5(m) prior to such reduction) and (B) the denominator of which shall be the original amount of the Offered Securities. In the event that such Investor so
      elects to reduce the number or amount of Offered Securities specified in its Notice of Acceptance, the Company may not issue, sell or exchange more than the reduced number or amount of the Offered Securities unless and until such securities have
      again been offered each Investor in accordance with Section 5(m)(i) and (ii) above.

    

    

    (vii)         Upon the closing of the issuance, sale or exchange of all or less than all of the Other Securities, such Investor shall acquire from the Company, and the Company
      shall issue to such Investor, the number or amount of the Basic Amount (and with respect to the Lead Investor only, the number or amount of the Undersubscription Amount in addition to the Lead Investor’s Basic Amount) specified in its Notice of
      Acceptance, as reduced pursuant to Section 5(m)(vi) above if such Investor has so elected, upon the terms and conditions specified in the Subsequent Financing Agreement. The purchase by such Investor of any Offered Securities is subject in all cases
      to the preparation, execution and delivery by the Company and such Investor of a separate purchase agreement relating to such Offered Securities reasonably satisfactory in form and substance to such Investor and its counsel. Any Offered Securities
      not acquired by an Investor or other Persons in accordance with this Section 5(m) may not be issued, sold or exchanged until they are again offered to the Investors under the procedures specified in this Section 5(m).

    

    

    (viii)        The Company and each Investor agree that, if any Investor elects to participate in the Subsequent Financing, the transaction documents related to the Subsequent
      Financing shall not include any term or provision that, directly or indirectly, will, or is intended to, exclude one or more of the Investors from participating in a Subsequent Financing, including, but not limited to, provisions whereby such
      Investor shall be required to agree to any restrictions on trading as to any of the Securities purchased hereunder or be required to consent to any amendment to or termination of, or grant any waiver, release or the like under or in connection with,
      this Agreement, without the prior written consent of such Investor.  In addition, the Company and each Investor agree that, in connection with a Subsequent Financing, the transaction documents related to the Subsequent Financing shall include a
      requirement for the Company to issue a widely disseminated press release by 9:30 am (New York City time) on the Business Day of execution of the transaction documents in such Subsequent Financing (or, if the date of execution is not a Business Day,
      on the immediately following Business Day) that discloses the material terms of the transactions contemplated by the transaction documents in such Subsequent Financing.

    

    

    (ix)          Notwithstanding anything to the contrary in this Section 5(m) and unless otherwise agreed to by such Investor, the Company shall either confirm in writing to such
      Investor that the transaction with respect to the Subsequent Financing has been abandoned or shall publicly disclose its intention to issue the Offered Securities, in either case, in such a manner such that such Investor will not be in possession of
      any material, non-public information, by the fifth (5th) Business Day following delivery of the Subsequent Financing Notice. If by such fifth (5th) Business Day, no public disclosure regarding a transaction with respect to the Offered Securities has been made, and no notice regarding the abandonment of such
      transaction has been received by such Investor, such transaction shall be deemed to have been abandoned and such Investor shall not be in possession of any material, non-public information with respect to the Company or any of its Subsidiaries.
      Should the Company decide to pursue such transaction with respect to the Offered Securities, the Company shall provide such Investor with another Subsequent Financing Notice and such Investor will again have the right of participation set forth in
      this Section 5(m).

    
      -24-

      
        


    

    

    

    (x)           The restrictions contained in this Section 5(m) shall not apply in connection with (i) an Exempt Issuance, (ii) beginning on the Business Day immediately following
      the last day of the Restricted Period (and in no event during the Restricted Period) or thereafter, the issuance of any securities of the Company in connection with a merger, joint venture, licensing arrangement or any other similar non-capital
      raising transaction, provided that any such issuance shall only be to a Person (or to the equity holders of a Person) which is, itself or through its subsidiaries, an operating company or an owner of an asset in a business synergistic with the
      business of the Company, or (iii) beginning on the Business Day immediately following the last day of the Restricted Period (and in no event during the Restricted Period) or thereafter, the issuance of any Common Stock by the Company in a firm
      commitment underwritten public offering of Common Stock by the Company.

    

    

    (n)          Other Transactions. The Company shall not enter into, announce or recommend to its stockholders any agreement, plan, arrangement or transaction in or of which the terms thereof
      would restrict, materially delay, conflict with or impair the ability or right of the Company to perform its obligations under any of the Transaction Documents to which it is a party, including, without limitation, the obligation of the Company to
      deliver the Purchase Shares and the Warrants to the Investors in accordance with the terms of this Agreement, or to deliver the Warrant Shares upon exercise of the Warrants in accordance with the terms of the Warrants.

    

    

    (o)          Corporate Existence.   So long as any of the Investors beneficially owns any portion of any of the Warrants, the Company shall not be party to any Fundamental Transaction (as
      defined in the Warrant) unless the Company is in compliance with the applicable provisions governing Fundamental Transactions set forth in the Warrants.

    

    

    (p)          Exercise Procedures. The form of Exercise Notice (as defined in the Warrants) included in the Warrants sets forth the totality of the procedures required of the Investors in order
      to exercise the Warrants. No legal opinion or other information or instructions shall be required of any Investor to exercise any portion of such Investor’s Warrants. The Company shall honor exercises of the Warrants and shall deliver the applicable
      number of Warrant Shares in accordance with the terms, conditions and time periods set forth in the Warrants. Without limiting the preceding sentences, no ink-original Exercise Notice shall be required, nor shall any medallion guarantee (or other
      type of guarantee or notarization) of any Exercise Notice form be required in order to exercise any portion of any of the Warrants.

    

    

    (q)          Issuance of Warrant Shares Upon Exercise of Warrants Unconditional and Absolute. The Company acknowledges that its obligations under this Agreement and the Warrants with respect
      to the Warrant Shares, including, without limitation, its obligation to issue the Warrant Shares upon exercise of the Warrants, are unconditional and absolute and not subject to any right of set off, counterclaim, delay or reduction, regardless of
      the effect of any such dilution or any claim the Company may have against any Investor and regardless of the dilutive effect that such issuance may have on the ownership of the other stockholders of the Company.

    

    

    (r)          Equal Treatment of Investors. No consideration (including any modification of any Transaction Document) shall be offered or paid to any Person to amend or consent to a waiver or
      modification of any provision of the Transaction Documents unless the same consideration is also offered to all of the parties to such Transaction Documents. For clarification purposes, this provision constitutes a separate right granted to each
      Investor by the Company and negotiated separately by each Investor, and is intended for the Company to treat the Investors as a class and shall not in any way be construed as the Investors acting in concert or as a group with respect to the purchase,
      disposition or voting of Securities or otherwise.

    

    

    (s)          Shareholders’ Rights Plan. No claim will be made or enforced by the Company or, with the consent of the Company, any other Person, that any Investor is an “Acquiring Person” under
      any control share acquisition, business combination, poison pill (including any distribution under a rights agreement) or similar anti-takeover plan or arrangement in effect or hereafter adopted by the Company, or that any Investor could be deemed to
      trigger the provisions of any such plan or arrangement, by virtue of receiving Securities under the Transaction Documents or under any other agreement between the Company and the Investors.

    6.          TRANSFER AGENT.

    

    

    The Company represents and warrants that the Securities shall otherwise be freely transferable on the books and records of the Company, as applicable, to the extent provided in this Agreement and the
      other Transaction Documents.  If an Investor effects a sale, assignment or transfer of the Securities, the Company shall permit the transfer and shall promptly instruct its Transfer Agent to issue one or more certificates or credit shares to the
      applicable balance accounts at DTC in such name and in such denominations as specified by such Investor to effect such sale, transfer or assignment.  The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable
      harm to an Investor. Accordingly, the Company acknowledges that the remedy at law for a breach of its obligations under this Section 6 will be inadequate and agrees, in the event of a breach or threatened breach by the Company of the provisions of
      this Section 6, that an Investor shall be entitled, in addition to all other available remedies, to an order and/or injunction restraining any breach and requiring immediate issuance and transfer, without the necessity of showing economic loss and
      without any bond or other security being required.  The Company shall cause its counsel to issue a legal opinion to the Transfer Agent in form and substance reasonably acceptable to Investors which purchased at least 50.1% in interest of the Purchase
      Shares and corresponding Warrants, including the Lead Investor (the “Required Investors”)  as follows: (i) at the Closing with respect to the Purchase Shares, (ii) upon each exercise of the Warrants with respect to the Warrant Shares (unless
      such issuance is covered by a prior legal opinion previously delivered to the Transfer Agent), and (iii) on each date a registration statement with respect to the issuance or resale of any of the Warrant Shares is declared effective by the SEC. Any
      fees (with respect to the Transfer Agent, counsel to the Company or otherwise) associated with the issuance of such opinions shall be borne by the Company.

    

    

    	

          	7.

          	9.	
            INDEMNIFICATION.

          


    

    

    In consideration of the Investors’ execution and delivery of this Agreement and acquiring the Purchase Shares and the Warrants hereunder, and in addition to all of the Company’s other obligations
      under the Transaction Documents to which it is a party, the Company shall defend, protect, indemnify and hold harmless each Investor and all of its affiliates, stockholders, officers, directors and employees and any of the foregoing Person’s agents
      or other representatives (including, without limitation, those retained in connection with the transactions contemplated by the Transaction Documents) (collectively, the “Indemnitees”) from and against any and
      all actions, causes of action, suits, claims, losses, costs, penalties, fees, liabilities and damages, and expenses in connection therewith (irrespective of whether any such Indemnitee is a party to the action for which indemnification hereunder is
      sought), and including reasonable attorneys’ fees and disbursements (the “Indemnified Liabilities”), incurred by any Indemnitee as a result of, or arising out of, or relating to: (a) any misrepresentation or breach of any representation or
      warranty made by the Company in any of the Transaction Documents or any other certificate, instrument or document contemplated hereby or thereby, (b) any breach of any covenant, agreement or obligation of the Company contained in any of the
      Transaction Documents or any other certificate, instrument or document contemplated hereby or thereby, (c) any cause of action, suit or claim brought or made against such Indemnitee and arising out of or resulting from the execution, delivery,
      performance or enforcement of any of the Transaction Documents or any other certificate, instrument or  document contemplated hereby or thereby, (d) any violation of the Securities Act, the Exchange Act, state securities or “Blue Sky” laws, or the
      rules and regulations of the Principal Market in connection with the transactions contemplated by the Transaction Documents by the Company or any of its affiliates, officers, directors or employees, (e) any untrue statement or alleged untrue
      statement of a material fact contained, or incorporated by reference, in the Registration Statement or any amendment thereto or any omission or alleged omission to state therein, or in any document incorporated by reference therein, a material fact
      required to be stated therein or necessary to make the statements therein not misleading, or (f) any untrue statement or alleged untrue statement of a material fact contained, or incorporated by reference, in the Prospectus, or any omission or
      alleged omission to state therein, or in any document incorporated by reference therein, a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not
      misleading; provided, however, that (I) the indemnity contained in clause (c) of this Section 9 shall not apply to any Indemnified Liabilities which directly and primarily result from the fraud, gross negligence or willful misconduct of an
      Indemnitee, (II) the indemnity contained in clauses (d), (e) and (f) of this Section 9 shall not apply to any Indemnified Liabilities of an Investor to the extent, but only to the extent, arising out of or based upon any untrue statement or alleged
      untrue statement or omission or alleged omission made in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Investor expressly for use in any Prospectus Supplement (it being hereby acknowledged
      and agreed that the written information set forth on Exhibit D attached hereto with respect to the Lead Investor is the only written information furnished to the Company by or on behalf of the Lead
      Investor expressly for use in the Initial Prospectus Supplement), if the Prospectus was timely made available by the Company to such Investor pursuant to Section 5(l), (III) the indemnity contained in clauses (d), (e) and (f) of this Section 9 shall
      not inure to the benefit of an Investor to the extent such Indemnified Liabilities are based on a failure of such Investor to deliver or to cause to be delivered the Prospectus made available by the Company, if such Prospectus was timely made
      available by the Company pursuant to Section 5(l), and if delivery of the Prospectus by such Investor was required under the Securities Act with respect to the Securities and such delivery by such Investor would have cured the defect giving rise to
      such Indemnified Liabilities, and (IV) the indemnity in this Section 9 shall not apply to amounts paid in settlement of any claim if such settlement is effected without the prior written consent of the Company, which consent shall not be unreasonably
      withheld, conditioned or delayed. To the extent that the foregoing undertaking by the Company may be unenforceable for any reason, the Company shall make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities
      which is permissible under applicable law.  Any required indemnification payment for any particular claim shall be made within thirty (30) days from the date an Investor makes a written request for it. A certificate containing reasonable detail as to
      the amount of such indemnification submitted to the Company by an Investor shall be conclusive evidence, absent manifest error, of the amount due from the Company to such Investor. If any action shall be brought against any Indemnitee in respect of
      which indemnity may be sought pursuant to this Agreement, such Indemnitee shall promptly notify the Company in writing, and the Company shall have the right to assume the defense thereof with counsel of its own choosing reasonably acceptable to the
      Indemnitee. Any Indemnitee shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Indemnitee, except to the extent that (i)
      the employment thereof has been specifically authorized by the Company in writing, (ii) the Company has failed after a reasonable period of time to assume such defense and to employ counsel or (iii) in such action there is, in the reasonable opinion
      of such separate counsel, a material conflict on any material issue between the position of the Company and the position of such Indemnitee, in which case the Company shall be responsible for the reasonable fees and expenses of no more than one such
      separate counsel.

    10.          RESERVED.

    

    

    11.          TERMINATION

    

    

    This Agreement may be terminated only as follows:

    

    

    (a)          If pursuant to or within the meaning of any Bankruptcy Law, the Company commences a voluntary case or any Person commences a proceeding against the Company, a Custodian is appointed for
      the Company or for all or substantially all of its property, or the Company makes a general assignment for the benefit of its creditors, this Agreement shall automatically terminate without any liability or payment to the Company (except as set forth
      below) without further action or notice by any Person.

    

    

    (b)          In the event that the Closing shall not have occurred on or before June 15, 2021, due to the failure to satisfy the conditions set forth in Sections 7 and 8 above with respect to the
      Closing, either the Company, on the one hand, or any Investor, on the other hand, shall have the option to terminate this Agreement at the close of business on such date or thereafter without liability of any party to any other party (except as set
      forth below); provided, however, that the right to terminate this Agreement under this Section 11(b) shall not be available to any party if such party is then in breach of any covenant or agreement contained in this Agreement or any representation or
      warranty of such party contained in this Agreement fails to be true and correct such that the conditions set forth in Section 7(c) or Section 8(d), as applicable, could not then be satisfied. Any termination of this Agreement pursuant to this Section
      11(b) shall be effected by written notice from the Company to each of the Investors, or any Investor to the Company and each of the other Investors, as the case may be, setting forth the basis for the termination hereof.

    

    

    The representations and warranties and covenants of the Company and the Investors contained in Sections 3, 4, 5, and 6 hereof, the indemnification provisions set forth in Section 9 hereof and the agreements and
      covenants set forth in Sections 10, 11 and 12, shall survive the Closing and any termination of this Agreement.  No termination of this Agreement shall be deemed to release the Company or any Investor from any
      liability for intentional misrepresentation or willful breach by such party of any of the Transaction Documents to which it is a party.

    

    

    12.          MISCELLANEOUS.

    

    

    (a)          Governing Law; Jurisdiction; Jury Trial.  The corporate laws of the State of Delaware shall govern all issues concerning the relative rights of the Company and its stockholders.
      All other questions concerning the construction, validity, enforcement and interpretation of this Agreement and the other Transaction Documents shall be governed by the internal laws of the State of Illinois, without giving effect to any choice of
      law or conflict of law provision or rule (whether of the State of Illinois or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of Illinois.  Each party hereby irrevocably submits to the
      exclusive jurisdiction of the state and federal courts sitting in the State of Illinois, County of Cook, for the adjudication of any dispute hereunder or under the other Transaction Documents or in connection herewith or therewith, or with any
      transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action
      or proceeding is brought in an inconvenient forum or that the venue of such suit, action or proceeding is improper.  Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or
      proceeding by mailing a copy thereof to such party at the address for such notices to it under this Agreement and the other Transaction Documents and agrees that such service shall constitute good and sufficient service of process and notice
      thereof.  Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law.  EACH PARTY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE, AND AGREES NOT TO
        REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION HEREWITH OR ARISING OUT OF THIS AGREEMENT OR ANY OF THE OTHER TRANSACTION DOCUMENTS OR ANY TRANSACTION CONTEMPLATED HEREBY OR THEREBY.

    
      -30-

      
        


    

    

    

    (b)          Counterparts.  This Agreement may be executed in two or more identical counterparts, all of which 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; provided that a facsimile signature or signature delivered by e-mail in a “.pdf” format data file, including any electronic signature complying with the U.S. federal ESIGN
      Act of 2000, e.g., www.docusign.com, www.echosign.adobe.com, etc., shall be considered due execution and shall be binding upon the signatory thereto with the same force and effect as if the signature were an original signature.

    

    

    (c)          Headings.  The headings of this Agreement are for convenience of reference and shall not form part of, or affect the interpretation of, this Agreement.

    

    

    (d)          Severability.  If any provision of this Agreement shall be invalid or unenforceable in any jurisdiction, such invalidity or unenforceability shall not affect the validity or
      enforceability of the remainder of this Agreement in that jurisdiction or the validity or enforceability of any provision of this Agreement in any other jurisdiction.

    

    

    (e)          Entire Agreement; Amendment.  This Agreement and the other Transaction Documents supersede all other prior oral or written agreements among the Investors, the Company, their
      respective affiliates and Persons acting on their behalf with respect to the subject matter hereof, and this Agreement, the other Transaction Documents and the instruments referenced herein contain the entire understanding of the parties with respect
      to the matters covered herein and therein and, except as specifically set forth herein or therein, neither the Company nor any of the Investors makes any representation, warranty, covenant or undertaking with respect to such matters.  The Company
      acknowledges and agrees that is has not relied on, in any manner whatsoever, any representations or statements, written or oral, other than as expressly set forth in the Transaction Documents. No provision of this Agreement may be waived, modified,
      supplemented or amended except in a written instrument signed, in the case of an amendment, by the Company and the Required Investors (or, prior to the Closing, the Company and each Investor) or, in the case of a waiver, by the party against whom
      enforcement of any such waived provision is sought.  No waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a
      waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of any party to exercise any right hereunder in any manner impair the exercise of any such right. Any amendment effected in accordance with this Section
      12(e) shall be binding upon each Investor and the Company.

    

    

    (f)          Notices.  Any notices, consents, waivers or other communications required or permitted to be given under the terms of this Agreement must be in writing and will be deemed to have
      been delivered: (i) upon receipt when delivered personally; (ii) (a) at the time of transmission, if such notice or communication is delivered via facsimile (provided confirmation of transmission is mechanically or electronically generated and kept
      on file by the sending party) at the facsimile number as set forth below or on Schedule I or email attachment (provided that no automated message of failure of delivery is generated by the sender’s server at the time of transaction) at the email

      automated message of failure of delivery is generated by the sender’s server at the time of transaction) at the email address as set forth below or on Schedule I on a day that is not a Trading Day or later than 5:30 p.m. (New York City time) on any
      Trading Day (provided confirmation of transmission is mechanically or electronically generated and kept on file by the sending party); or (iii) one Business Day after deposit with a nationally recognized overnight delivery service, in each case
      properly addressed to the party to receive the same. The addresses for such communications shall be:

      containing the time, date, and recipient facsimile number or email address, as applicable, and an image of the first page of such transmission or (C) provided by a nationally recognized overnight delivery service, shall be rebuttable evidence of

    (g)          Successors and Assigns.  This Agreement shall be binding upon and inure to the benefit of the parties and any permitted successors and assigns of the Company.  The Company shall
      not assign this Agreement or any rights or obligations hereunder without the prior written consent of each of the Investors, including by merger or consolidation.  None of the Investors may assign its rights or obligations under this Agreement.

    
      -32-

      
        


    

    

    

    (h)          No Third Party Beneficiaries.  The Placement Agent shall be the third party beneficiary of the representations and warranties of each Investor, severally and only with respect to
      itself and not jointly, in Section 3, and the representations and warranties of the Company in Section 4. This Agreement is intended for the benefit of the parties hereto and any permitted successors and assigns of the Company and, except as set
      forth in Section 9, is not for the benefit of, nor may any provision hereof be enforced by, any other Person.

    

    

    (i)          Publicity.  The Company shall afford each of the Investors and its counsel with the opportunity to review and comment upon the form and substance of, and shall give reasonable
      consideration to all such comments from such Investor or its counsel on, any press release, SEC filing or any other public disclosure by or on behalf of the Company relating to such Investor, its purchases hereunder or any aspect of the Securities,
      any of the Transaction Documents or the transactions contemplated thereby, not less than 24 hours prior to the issuance, filing or public disclosure thereof. Each Investor must be provided with a final version of any such press release, SEC filing or
      other public disclosure at least 24 hours prior to any release, filing or use by the Company thereof. The Company agrees and acknowledges that its failure to fully comply with this provision constitutes a Material Adverse Effect.  Except as
      contemplated in Section 5(f) hereof, no Investor shall issue a press release or any other public disclosure regarding this Agreement or the substance hereof without the prior written consent of the Company, which consent shall not be unreasonably
      withheld, conditioned or delayed.

    

    

    (j)          Further Assurances.  Each party shall do and perform, or cause to be done and performed, all such further acts and things, and shall execute and deliver all such other agreements,
      certificates, instruments and documents, as the other party may reasonably request in order to carry out the intent and accomplish the purposes of this Agreement and the consummation of the transactions contemplated hereby.

    

    

    (k)          No Financial Advisor, Placement Agent, Broker or Finder.    The Company represents and warrants to each of the Investors that, except for the Placement Agent and for the
      obligations set forth in the placement agency agreement between the Company and the Placement Agent, dated June 4, 2021, it has not engaged any financial advisor, placement agent, broker or finder in connection with the transactions contemplated
      hereby.  Each Investor, severally and only with respect to itself and not jointly, represents and warrants to the Company that it has not engaged any financial advisor, placement agent, broker or finder in connection with the transactions
      contemplated hereby.  The Company shall be responsible for the payment of any fees or commissions, if any, of any financial advisor, placement agent, broker or finder relating to or arising out of the transactions contemplated hereby.  The Company
      shall pay, and hold each of the Investors harmless against, any liability, loss or expense (including, without limitation, attorneys’ fees and out of pocket expenses) arising in connection with any such claim.

    

    

    (l)          No Strict Construction.  The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict
      construction will be applied against any party.

    

    

    (m)          Remedies, Other Obligations, Breaches and Injunctive Relief.  The Investors’ remedies provided in this Agreement, including, without limitation, the Investors’ remedies provided
      in Section 9, shall be cumulative and in addition to all other remedies available to the Investors under this Agreement, at law or in equity (including a decree of specific performance and/or other injunctive relief), no remedy of any of the
      Investors contained herein shall be deemed a waiver of compliance with the provisions giving rise to such remedy and nothing herein shall limit any Investor’s right to pursue actual damages for any failure by the Company to comply with the terms of
      this Agreement.  The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Investors and that the remedy at law for any such breach may be inadequate.  The Company therefore agrees that, in the event
      of any such breach or threatened breach, any Investor shall be entitled, in addition to all other available remedies, to an injunction restraining any breach, without the necessity of showing economic loss and without any bond or other security being
      required.

    
      -33-

      
        


    

    

    

    (n)          Enforcement Costs.  If: (i) this Agreement is placed by any Investor in the hands of an attorney for enforcement or is enforced by any Investor through any legal proceeding; (ii)
      an attorney is retained to represent any Investor in any bankruptcy, reorganization, receivership or other proceedings affecting creditors’ rights and involving a claim under this Agreement; or (iii) an attorney is retained to represent any Investor
      in any other proceedings whatsoever in connection with this Agreement, then the Company shall pay to such Investor, as incurred by such Investor, all reasonable costs and expenses including attorneys’ fees incurred in connection therewith, in
      addition to all other amounts due hereunder. If this Agreement is placed by the Company in the hands of an attorney for enforcement against an Investor or is enforced by the Company against an Investor through any legal proceeding, then such Investor
      against whom this Agreement is so enforced shall pay to the Company, as incurred by the Company, all reasonable costs and expenses including reasonable attorneys’ fees incurred in connection therewith, in addition to all other amounts due hereunder.

    

    

    (o)          [Reserved].

    

    

    (p)          Independent Nature of Investors’ Obligations and Rights.  The obligations of each Investor under the Transaction Documents 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.  Nothing contained herein or in any other Transaction Document, and no action taken by any
      Investor pursuant hereto or thereto, shall be deemed to constitute the Investors as, and the Company acknowledges that the Investors do not so constitute, a partnership, an association, a joint venture or any other kind of group or entity, or create
      a presumption that the Investors are in any way acting in concert or as a group or entity with respect to such obligations or the transactions contemplated by the Transaction Documents or any matters, and the Company acknowledges that the Investors
      are not acting in concert or as a group, and the Company shall not assert any such claim, with respect to such obligations or the transactions contemplated by the Transaction Documents. The decision of each Investor to purchase the Purchase Shares
      and the Warrants pursuant to the Transaction Documents has been made by such Investor independently of any other Investor. Each Investor acknowledges that no other Investor has acted as agent for such Investor in connection with such Investor making
      its investment hereunder and that no other Investor will be acting as agent of such Investor in connection with monitoring such Investor’s investment in the Securities or enforcing its rights under the Transaction Documents. The Company and each
      Investor confirms that each Investor has independently participated with the Company in the negotiation of the transaction contemplated hereby with the advice of its own counsel and advisors. Each Investor shall be entitled to independently protect
      and enforce its rights, including, without limitation, the rights arising out of this Agreement, the Warrants or out of any 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 use of a single agreement to effectuate the purchase and sale of the Purchase Shares and the Warrants contemplated hereby was solely in the control of the Company, not the action or decision of any Investor, and was
      done solely for the convenience of the Company 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 and in each other Transaction Document is
