                  designate by written notice in accordance with the provisions of this Agreement. Whenever any amount expressed to be due by the terms of this Agreement is due on any day that is not a Business Day, the same shall instead be due on the
                  next succeeding day that is a Business Day.

                (i)

              	
                Exchange Cap. The Company shall not issue or sell any shares of Common Stock pursuant to this Agreement, and the Investor shall not purchase or acquire any
                  shares of Common Stock pursuant to this Agreement, to the extent that after giving effect thereto, the aggregate number of shares of Common Stock that would be issued pursuant to this Agreement and the transactions contemplated hereby
                  would be equal to or greater than 3,269,606 shares of Common Stock (subject to adjustment for any reorganization, recapitalization, non-cash dividend, stock split, reverse stock split or other similar transaction), representing 19.99% of
                  the shares of Common Stock outstanding on the Execution Date (which number of shares shall be reduced, on a share-for-share basis, by the number of shares of Common Stock issued or issuable pursuant to any transaction or series of
                  transactions that may be aggregated with the transactions contemplated by this Agreement under applicable rules of the Nasdaq Capital Market or any other Principal Market on which the Common Stock may be listed or quoted) (the “Exchange
                    Cap”), unless and until the Company elects to solicit stockholder approval of the issuance of Common Stock as contemplated by this Agreement and the stockholders of the Company have in fact approved such issuance in accordance with
                  the applicable rules and regulations of the Nasdaq Capital Market, any other Principal Market on which the Common Stock may be listed or quoted, and the Company’s Certificate of Incorporation, as amended and in effect as of the Execution
                  Date (the “Certificate of Incorporation”), and the Company’s Bylaws, as amended and in effect as of the Execution Date (the “Bylaws”). For the avoidance of doubt, the Company may, but shall be under no obligation to, request
                  its stockholders to approve the issuance of Common Stock as contemplated by this Agreement; provided, that if stockholder approval is not obtained in accordance with this Section 2(e)(i), the Exchange Cap shall be applicable for
                  all purposes of this Agreement and the transactions contemplated hereby at all times during the term of this Agreement (except as set forth in Section 2(e)(ii) below).

              


      

      

      

      
        	
                (ii)

              	
                General. The Company shall not issue any Securities pursuant to this Agreement if such issuance would reasonably be expected to result in (A) a violation of the Securities Act
                  or (B) a breach of the rules and regulations of the Principal Market. Furthermore, the Company agrees that it shall not issue any Securities pursuant to this Agreement if, at the time of such issuance (Y) the effectiveness of the
                  Registration Statement registering the Securities has lapsed for any reason (including, without limitation, the issuance of a stop order or similar order) or (Z) the Registration Statement is unavailable for the sale by the Company to the
                  Investor (or the resale by the Investor, as the case may be) of any or all of the Securities to be issued to the Investor under the Transaction Documents. The provisions of this Section 2(e) shall be implemented in a manner other
                  than in strict conformity with the terms hereof only if necessary to ensure compliance with the Securities Act and the rules and regulations of the Principal Market.

              


      

      

      

      
        	
                (e)

              	
                Beneficial Ownership Limitation. Notwithstanding anything to the contrary contained in this Agreement, the Company shall not issue or sell, and the Investor shall not purchase or
                  acquire, any Common Stock under this Agreement that, when aggregated with all other shares of Common Stock then beneficially owned by the Investor and its affiliates (as calculated pursuant to Section 13(d) of the Exchange Act and Rule
                  13d-3 promulgated thereunder) would result in the beneficial ownership by the Investor and its affiliates of more than 4.99% of the then issued and outstanding Common Stock (the “Beneficial Ownership Limitation”); provided,
                  however, that if such Beneficial Ownership Limitation is reached due, in whole or in part, to purchases of Common Stock by the Investor other than from the Company, the Investor shall promptly dispose of such shares purchased other
                  than from the Company to the extent necessary to permit the Company to issue Common Stock to the Investor pursuant to this Agreement. The Beneficial Ownership Limitation shall not be waived without the written consent of the Company and
                  the Investor. Upon the written or oral request of the Investor, the Company shall promptly (but not later than the following Business Day) confirm orally or in writing to the Investor the amount of Common Stock then outstanding. The
                  Investor and the Company shall each cooperate in good faith in the determinations required hereby and the application hereof.

                  an opportunity to ask questions of and receive answers from the officers of the Company concerning the financial condition and business of the Company and others matters related to an investment in the Securities. Neither such inquiries
                  nor any other due diligence investigations conducted by the Investor or its representatives shall modify, amend or affect the Investor’s right to rely on the Company’s representations and warranties contained in Section 4 below. The
                  Investor has sought such accounting, legal and tax advice from its own independent advisors as it has considered necessary to make an informed investment decision with respect to its acquisition of the Securities and is not relying on any
                  accounting, legal, tax or other advice from the Company or its officers, employees, representatives or advisors. The Investor acknowledges and agrees that the Company neither makes nor has made any representations or warranties with

                  or endorsement of the Securities or the fairness or suitability of an investment in the Securities nor have such authorities passed upon or endorsed the merits of the transactions contemplated hereby.

                  corporation or other entity in each jurisdiction in which the nature of the business conducted or property owned by it makes such qualification necessary, except where the failure to be so qualified or in good standing, as the case may
                  be, would not have or would not reasonably be expected to result in a Material Adverse Effect, and to the Company’s knowledge, no proceeding has been instituted in any such jurisdiction revoking, limiting or curtailing or seeking to
                  revoke, limit or curtail such power and authority or qualification. The Company has no Subsidiaries, except as set forth on Exhibit 21.1 to the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 filed with the SEC

                Title. Except as set forth in the SEC Documents, the Company and its Subsidiary have good and marketable title in all real property and personal property owned by them that is
                  material to the business of the Company and its Subsidiary, in each case free and clear of all liens, encumbrances and defects (“Liens”), except (i) for Liens as do not materially affect the value of such property or do not

                  Company nor its 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 have a Material Adverse Effect.

                  businesses, and neither the Company nor its Subsidiary has received any written notice of proceedings relating to the revocation or modification of any such Authorization, except for such revocations or modifications that would not be
                  reasonably expected to have a Material Adverse Effect.

                  reports and declarations required by any jurisdiction to which it is subject (unless and only to the extent that the Company and its Subsidiary have 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, and except as could not reasonably be expected to have a
                  Material Adverse Effect. 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.

                Registration Statement. The Company has prepared and filed the Registration Statement with the SEC in accordance with the Securities Act. The Registration Statement was declared
                  effective by order of the SEC on March 11, 2020 (File No. 333-236416). 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, to the knowledge of the Company, has
                  threatened in writing to do so. The “Plan of Distribution” section of the Prospectus permits the issuance of the Securities under the terms of this Agreement. At the time the Registration Statement and any amendments thereto became
                  effective, at the Execution Date 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, in light of the
                  circumstances under which they were made, 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 Commencement 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 representation and warranty does not apply to statements in or omissions from any Prospectus Supplement made in
                  reliance upon and in conformity with information relating to the Investor furnished to the Company in writing by or on behalf of the 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 in reliance on General Instruction I.B.1 of Form S-3 and the conditions set forth in Instruction 3 to General Instruction I.B.6 of Form S-3 for the offering and sale of the
                  Securities contemplated by this Agreement, 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 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 Statement that the Company or another participant in the transactions
                  contemplated hereby made a bona fide offer (within the meaning of Rule 164(h)(2) of the Securities Act) relating to any of the Securities, the Company was not, and as of the Execution Date the Company is, not an “Ineligible Issuer” (as
                  defined in Rule 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 the Investor does not hold any of the Securities, shall not
                  distribute any offering material in connection with the offering and sale of any of the Securities, to or by the Investor, 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 shall not make an offer relating to the Securities that would constitute a “free writing prospectus” as defined in Rule 405 under
                  the Securities Act.

                Accounting Controls; Sarbanes-Oxley. The Company maintains a system of internal accounting controls sufficient to provide reasonable assurances that (A) transactions are executed
                  in accordance with management’s general or specific authorization; (B) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain accountability for assets; (C) access to
                  assets is permitted only in accordance with management’s general or specific authorization; and (D) the recorded accountability for assets is compared with existing assets at reasonable intervals and appropriate action is taken with
                  respect to any differences. Except as disclosed in the SEC Documents, the Company has concluded that its internal control over financial reporting is effective and the Company is not aware of any “significant deficiencies” or “material
                  weaknesses” (each as defined by the rules adopted by the SEC) in its internal control over financial reporting, or any fraud, whether or not material, that involves management or other employees of the Company and its Subsidiary who have
                  a significant role in the Company’s internal controls; and since the end of the latest audited fiscal year, there has been no change in the Company’s internal control over financial reporting (whether or not remediated) that has
                  materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting. The Board of Directors has, subject to the exceptions, cure periods and the phase in periods specified in the
                  applicable stock exchange rules of the Principal Market (“Exchange Rules”), validly appointed an audit committee to oversee internal accounting controls whose composition satisfies the applicable independence and other requirements
                  of the Exchange Rules and the rules under the Exchange Act, and the Board of Directors has adopted a charter for the audit committee that satisfies the requirements of the Exchange Rules and the rules under the Exchange Act. No
                  relationship, direct or indirect, exists between or among the Company, on the one hand, and the directors, officers, stockholders, customers or suppliers of the Company, on the other hand, that is required to be described in the

                  from the Principal Market regarding the continued eligibility of the Common Stock for listing on the Principal Market; provided, however, that the Company shall not be required to provide the Investor copies of any such
                  notice that the Company reasonably believes constitutes material non-public information and the Company would not be required to publicly disclose such notice in any report or statement filed with the SEC and under the Exchange Act or the
                  Securities Act. 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

                  compliance with such permits, licenses and Authorizations and with Applicable Laws, except where the failure to maintain or be in compliance with such permits, licenses, Authorizations and Applicable Laws would not reasonably be expected
                  to have a Material Adverse Effect. The Company shall comply with all requirements imposed upon it by the Securities Act and the Exchange Act and applicable U.S. state securities or “blue sky” laws as from time to time may be in force in
                  connection with the offer, issuance and sale 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,

                  security of the Company. The Company will conduct its affairs in such a manner so as to reasonably ensure that neither it nor its Subsidiary will be or become, at any time prior to the termination of this Agreement, an “investment
                  company,” as such term is defined in the Investment Company Act, assuming no change in the SEC’s current interpretation as to entities that are not considered an investment company. Specifically, the Company and its Subsidiary will use
                  their commercially reasonable efforts to comply with all effective applicable provisions of the Sarbanes-Oxley Act and The Dodd–Frank Wall Street Reform and Consumer Protection Act.

                  purpose; and (iii) of the Company becoming aware of the happening of any event that makes any statement of a material fact made in the Registration Statement, the Prospectus or any Prospectus Supplement untrue or that requires the making
                  of any additions to or changes to the statements then made in the Registration Statement, the Prospectus or any Prospectus Supplement in order to state a material fact required by the Securities Act to be stated therein or necessary in
                  order to make the statements then made therein (in the case of the Prospectus or any Prospectus Supplement, in light of the circumstances under which they were made) not misleading, or of the necessity to amend the Registration Statement
                  or supplement the Prospectus or any Prospectus Supplement to comply with the Securities Act or any other law. The Company shall not be required to disclose to the Investor the substance or specific reasons of any of the events set forth
                  in clauses (i) through (iii) of the immediately preceding sentence, but rather, shall only be required to disclose that the event has occurred. The Company shall not deliver to the Investor any Purchase Notice, and the Investor shall not
                  be obligated to purchase any shares of Common Stock under this Agreement, during the continuation or pendency of any of the foregoing events. If at any time the SEC shall issue any stop order suspending the effectiveness of the
                  Registration Statement or prohibiting or suspending the use of the Prospectus or any Prospectus Supplement, the Company shall use commercially reasonable efforts to obtain the withdrawal of such order at the earliest possible time. The
                  Company shall furnish to the Investor, without charge, a copy of any correspondence from the SEC or the staff of the SEC to the Company or its representatives relating to the Registration Statement or the Prospectus, as the case may be.

                  afforded the opportunity to review and comment thereon at least two (2) Business Days prior to filing with the SEC, as the case may be and (b) the Company shall not have given due consideration to any comments thereon received from the
                  Investor or its counsel, unless the Company reasonably has determined that it is necessary to amend the Registration Statement or make any supplement to the Prospectus to comply with the Securities Act or any other applicable law or
                  regulation, in which case the Company shall promptly (but in no event later than two (2) business days) so inform the Investor, the Investor shall be provided with a reasonable opportunity to review and comment upon any disclosure
                  referring to the Investor, the Transaction Documents or the transactions contemplated thereby, as applicable, and the Company shall expeditiously furnish to the Investor a copy thereof. In addition, for so long as, in the reasonable
                  opinion of counsel for the Investor, the Prospectus is required to be delivered in connection with any acquisition or sale of Securities by the Investor, the Company shall not file any Prospectus Supplement with respect to the Securities
                  without furnishing to the Investor as many copies of such Prospectus Supplement, together with the Prospectus, as the Investor may reasonably request.

                (m)

              	
                Prospectus Delivery. The Company consents to the use of the Prospectus (and of each Prospectus Supplement thereto) in accordance with the provisions of the Securities Act and with
                  the securities or “blue sky” laws of the jurisdictions in which the Securities may be sold by the Investor, in connection with the offering and sale of the Securities and for such period of time thereafter as the Prospectus is required by
                  the Securities Act to be delivered in connection with sales of the Securities. The Company will make available to the Investor upon request, and thereafter from time to time will furnish to the Investor, as many copies of the Prospectus
                  (and each Prospectus Supplement thereto) as the Investor may reasonably request for the purposes contemplated by the Securities Act within the time during which the Prospectus is required by the Securities Act to be delivered in
                  connection with sales of the Securities. If during such period of time any event shall occur that in the reasonable judgment of the Company and its counsel, or in the reasonable judgment of the Investor and its counsel, is required to be
                  set forth in the Registration Statement, the Prospectus or any Prospectus Supplement or should be set forth therein in order to make the statements made therein (in the case of the Prospectus or any Prospectus Supplement, in light of the
                  circumstances under which they were made) not misleading, or if in the reasonable judgment of the Company and its counsel, or in the reasonable judgment of the Investor and its counsel, it is otherwise necessary to amend the Registration
                  Statement or supplement the Prospectus or any Prospectus Supplement to comply with the Securities Act or any other applicable law or regulation, the Company shall forthwith prepare and, subject to Section 5(l) above, file with the SEC an
                  appropriate amendment to the Registration Statement or an appropriate Prospectus Supplement and in each case shall expeditiously furnish to the Investor, at the Company’s expense, such amendment to the Registration Statement or such
                  Prospectus Supplement, as applicable, as may be necessary to reflect any such change or to effect such compliance. The Company shall have no obligation to separately advise the Investor of, or deliver copies to the Investor of, the SEC
                  Documents, all of which the Investor shall be deemed to have notice of.

                Aggregation. From and after the Execution Date, neither the Company, nor or any of its affiliates will, and the Company shall use commercially reasonable efforts to ensure that no
                  Person acting on 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 the transactions contemplated hereby to be aggregated
                  with other 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, unless stockholder approval is
                  obtained before the closing of such subsequent transaction in accordance with the rules of such Principal Market.

              


      

      

      

      
        	
                (p)

              	
                Other Transactions. During the term of this Agreement, the Company will not deliver a Purchase Notice to the Investor during any time where there is an effective agreement, plan,
                  arrangement or transaction that has the effect of materially restricting, delaying, conflicting with or impairing the ability or right of the Company to perform its obligations under the Transaction Documents, including, without
                  limitation, the obligation of the Company to deliver the Securities to the Investor in accordance with the terms of the Transaction Documents, and the Company will provide notice to the Investors within two (2) Business Days of entering
                  into such an agreement, plan, arrangement or transaction.

              


      

      

      

      
        	
                (q)

              	
                Required Filings Relating to Purchases. To the extent required under the Securities Act or under interpretations by the SEC thereof, as promptly as practicable after the close
                  of each of the Company’s fiscal quarters (or on such other dates as required under the Securities Act or under interpretations by the SEC thereof), the Company shall prepare a Prospectus Supplement, which will set forth the number of
                  Purchase Shares sold to the Investor during such quarterly period (or other relevant period), the purchase price for such Purchase Shares and the net proceeds received by the Company from such sales, and shall file such Prospectus
                  Supplement with the SEC pursuant to Rule 424(b) under the Securities Act (and within the time periods required by Rule 424(b) and Rule 430B under the Securities Act). If any such quarterly Prospectus Supplement is not required to be filed
                  under the Securities Act or under interpretations by the SEC thereof, the Company shall disclose the information referenced in the immediately preceding sentence in its annual report on Form 10-K or its quarterly report on Form 10-Q (as
                  applicable) in respect of the quarterly period that ended immediately before the filing of such report in which sales of Purchase Shares were made to the Investor under this Agreement, and file such report with the SEC within the
                  applicable time period required by the Exchange Act. The Company shall not file any Prospectus Supplement pursuant to this Section 5(q), and shall not file any report containing disclosure relating to such sales of Purchase Shares, unless
                  a copy of such Prospectus Supplement or disclosure has been submitted to the Investor a reasonable period of time before the filing and the Investor has not reasonably objected thereto (it being acknowledged and agreed that the Company
                  shall not submit any portion of any Form 10-K or Form 10-Q other than the specific disclosure relating to any sales of Purchase Shares). The Company shall also furnish copies of all such Prospectus Supplements to each exchange or market
                  in the United States on which sales of the Purchase Shares may be made as may be required by the rules or regulations of such exchange or market, if applicable.

      On the Commencement Date, the Company shall issue to the Transfer Agent, (i) irrevocable instructions in the form substantially similar to those used by the
        Investor in substantially similar transactions (the “Commencement Irrevocable Transfer Agent Instructions”) and (ii) the notice of effectiveness of the Registration Statement in the form attached as an exhibit to the Registration Rights
        Agreement (the “Notice of Effectiveness of Registration Statement”), to issue the Securities in accordance with the terms of this Agreement and the Registration Rights Agreement. All Securities to be issued from and after the Commencement
        Date to or for the benefit of the Investor pursuant to this Agreement shall be issued only as DWAC Shares. The Company represents and warrants to the Investor that, while this Agreement is effective, no instruction other than the Commencement
        Irrevocable Transfer Agent Instructions and the Notice of Effectiveness of Registration Statement referred to in this Section 6 shall be given by the Company to the Transfer Agent with respect to the Securities from and after Commencement, and the
        Securities covered by the Registration Statement shall otherwise be freely transferable on the books and records of the Company. The Company agrees that if the Company fails to fully comply with the provisions of this Section 6 within two (2)
        Business Days of the Investor providing the deliveries referred to above, the Company shall, at the Investor’s written instruction, purchase such shares of Common Stock containing the legended certificates or book-entry statements from the Investor
        at the greater of the (i) purchase price paid for such shares of Common Stock (as applicable) and (ii) the Closing Sale Price of the Common Stock on the date of the Investor’s written instruction.

        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 (e) 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) and (e) of this Section 9 shall not apply to any Indemnified Liabilities 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 the Investor expressly for use in any Prospectus Supplement (it being hereby acknowledged and agreed that the written information set forth
        on Exhibit C attached hereto is the only written information furnished to the Company by or on behalf of the Investor expressly for use in the Initial Prospectus Supplement), if the Prospectus was timely made available by the Company to the
        Investor pursuant to Section 5(l), (III) the indemnity contained in clauses (d) and (e) of this Section 9 shall not inure to the benefit of the Investor to the extent such Indemnified Liabilities are based on a failure of the 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 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 that is permissible under applicable law, provided that no seller of Securities guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any seller
        of Securities who was not guilty of fraudulent misrepresentation.

      

      

      Payment under this indemnification shall be made for any undisputed amounts within thirty (30) days from the date the Investor makes written request for
        it. The Indemnitee shall promptly repay any amount paid to it hereunder if it is ultimately determined, by a final and non-appealable order of a court of competent jurisdiction, that the Indemnitee is not entitled to be indemnified against such
        Indemnified Liabilities by the Company pursuant to this Agreement. 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.

                TERMINATION.

              


      

      

      

      This Agreement may be terminated only as follows:

      

      

      
        	
                (a)

                  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 (any of which would be an Event of Default as described in Sections 10(f), 10(g) and 10(h)
                  hereof), 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.

                  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.

                    Notice”) to the Investor electing to terminate this Agreement without any liability whatsoever of any party to any other party under this Agreement (except as set forth below in this Section 11). The Company Termination Notice shall
                  not be effective until one (1) Business Day after it has been received by the Investor.

      Except as set forth in Sections 11(a) (in respect of an Event of Default under Sections 10(f), 10(g),  10(h), 11(d), and 11(e), any termination of this
        Agreement pursuant to this Section 11 shall be effected by written notice from the Company to the Investor, or the Investor to the Company, as the case may be, setting forth the basis for the termination hereof. The representations and warranties
        and covenants of the Company and the Investor contained in Sections 3, 4, 5 (except for Subsections 5(f) and 5(p)), and 6 hereof, the indemnification provisions set forth in Section 9 hereof and the agreements and covenants set forth in Sections 11
        and 12 shall survive the Commencement and any termination of this Agreement. No termination of this Agreement shall (i) affect the Company’s or the Investor’s rights or obligations under this Agreement with respect to pending purchases, and the
        Company and the Investor shall complete their respective obligations with respect to any pending Purchases under this Agreement or (ii) be deemed to release the Company or the Investor from any liability for intentional misrepresentation or willful
        breach of any of the Transaction Documents.

                  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 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

                (i)

              	
                Publicity. The Company shall afford the Investor and its counsel with the opportunity to review and comment upon, shall consult with the Investor and its counsel on the form and
                  substance of, and shall give due consideration to all such comments from the Investor or its counsel on, any press release, SEC filing or any other public disclosure by or on behalf of the Company relating to the Investor, its purchases
                  hereunder or any aspect of the Transaction Documents or the transactions contemplated thereby, not less than 24 hours prior to the issuance, filing or public disclosure thereof. The Investor must be provided with a final version of any
                  information related to the Investor contained within such press release, SEC filing or other public disclosure at least 24 hours prior to any release, filing or use by the Company thereof, or such shorter time as is reasonably necessary.
                  The Company agrees and acknowledges that its failure to fully comply with this provision constitutes a Material Adverse Effect.

              


      

      

      

      
        	
                (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 the Investor that it has not engaged any financial advisor, placement agent,
                  broker or finder in connection with the transactions contemplated hereby. The Investor 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 engaged by the Company relating to or arising out of the
                  transactions contemplated hereby. The Company shall pay, and hold the Investor harmless against, any liability, loss or expense (including, without limitation, reasonable attorneys’ fees and out of pocket expenses) arising in connection
                  with any such claim.

                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

                (m)

              	
                Remedies, Other Obligations, Breaches and Injunctive Relief. The Investor’s remedies provided in this Agreement, including, without limitation, the Investor’s remedies provided in
                  Section 9, shall be cumulative and in addition to all other remedies available to the Investor under this Agreement, at law or in equity (including a decree of specific performance and/or other injunctive relief), no remedy of the
                  investor contained herein shall be deemed a waiver of compliance with the provisions giving rise to such remedy and nothing herein shall limit the Investor’s right to pursue actual damages for any failure by the other party to comply with
                  the terms of this Agreement. The parties acknowledge that a breach by any party of its obligations hereunder will cause irreparable harm to the non-breaching party and that the remedy at law for any such breach may be inadequate. The
                  parties therefore agree that, in the event of any such breach or threatened breach, the non-breaching party 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.

              


      

      

      

      
        	
                (n)

              	
                Enforcement Costs. If: (i) this Agreement is placed by the Investor in the hands of an attorney for enforcement or is enforced by the Investor through any legal proceeding; (ii)
                  an attorney is retained to represent the 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
                  the Investor in any other proceedings whatsoever in connection with this Agreement, then the Company shall pay to the Investor, as incurred by the Investor, all reasonable and documented 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 or is enforced by the Company through any legal proceeding, then the
                  Investor shall pay to the Company, as incurred by the Company, all reasonable and documented costs and expenses, including attorneys’ fees incurred in connection therewith, in addition to all other amounts due hereunder.

              


      

      

      

      
        	
                (o)

              	
                Waivers. No provision of this Agreement may be waived other than in a written instrument signed by the party against whom enforcement of such waiver is sought. No failure or
                  delay in the exercise of any power, right or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such power, right or privilege preclude other or further exercise thereof or of any other
                  right, power or privilege.

              


      

      

      

      
        	
                (p)

              	
                Adjustments for Stock Splits. The parties acknowledge and agree that all share-related numbers contained in this Agreement shall be adjusted to take into account any
                  reorganization, recapitalization, non-cash dividend, stock split, reverse stock split or other similar transaction with respect to the Common Stock except as specifically stated herein.
