and all applicable rules and regulations promulgated by the Commission thereunder that are effective as of the date hereof and as of the

filed periodic report under the Exchange Act (such date, the “Evaluation Date”). The Company presented in its most
recently filed periodic report under the Exchange Act the conclusions of the certifying officers about the effectiveness of the disclosure
controls and procedures based on their evaluations as of the Evaluation Date. Since the Evaluation Date, there have been no changes in

Listing and Maintenance Requirements. The Common Stock is registered pursuant to Section 12(b)

any Trading Market on which the Common Stock is or has been listed or quoted to the effect that the Company is not in compliance with
the listing or maintenance requirements of such Trading Market. The Company is, and has no reason to believe that it will not in the foreseeable

necessary action, if any, in order to render inapplicable any control share acquisition, business combination, poison pill (including
any distribution under a rights agreement) or other similar anti-takeover provision under the Company’s certificate of incorporation
(or similar charter documents) or the laws of its state of incorporation that is or could become applicable to the Purchasers as a result
of the Purchasers and the Company fulfilling their obligations or exercising their rights under the Transaction Documents, including without
limitation as a result of the Company’s issuance of the Securities and the Purchasers’ ownership of the Securities.


(y)            
Disclosure. Except with respect to the material terms and conditions of the transactions contemplated
by the Transaction Documents, the Company confirms that neither it nor any other Person acting on its behalf has provided any of the Purchasers
or their agents or counsel with any information that it believes constitutes or might constitute material, non-public information which
is not otherwise disclosed in the Pricing Prospectus and the Prospectus. The Company understands and confirms that the Purchasers will
rely on the foregoing representation in effecting transactions in securities of the Company. All of the disclosure furnished by or on
behalf of the Company to the Purchasers regarding the Company and its Subsidiaries, their respective businesses and the transactions contemplated
hereby, including the Disclosure Schedules to this 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 the 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
therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made and when made,
not misleading. The Company acknowledges and agrees that no Purchaser makes or has made any representations or warranties with respect
to the transactions contemplated hereby other than those specifically set forth in Section 3.2 hereof.


(z)            
No Integrated Offering. Assuming the accuracy of the Purchasers’ representations and
warranties set forth in Section 3.2, neither the Company, nor any of its Affiliates, nor any Person acting on its or their behalf has,
directly or indirectly, made any offers or sales 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 for purposes of any applicable shareholder
approval provisions of any Trading Market on which any of the securities of the Company are listed or designated.


(aa)         
Solvency. Based on the consolidated financial condition of the Company as of the Closing Date,
after giving effect to the receipt by the Company of the proceeds from the sale of the Securities hereunder, (i) the fair saleable value
of the Company’s assets exceeds the amount that will be required to be paid on or in respect of the Company’s existing debts
and other liabilities (including known contingent liabilities) as they mature, (ii) the Company’s assets do not constitute unreasonably
small capital to carry on its business as now conducted and as proposed to be conducted including its capital needs taking into account
the particular capital requirements of the business conducted by the Company, consolidated and projected capital requirements and capital
availability thereof, and (iii) the current cash flow of the Company, together with the proceeds the Company would receive, were it to
liquidate all of its assets, after taking into account all anticipated uses of the cash, would be sufficient to pay all amounts on or
in respect of its liabilities when such amounts are required to be paid. The Company does not intend to incur debts beyond its ability
to pay such debts as they mature (taking into account the timing and amounts of cash to be payable on or in respect of its debt). The
Company has no knowledge of any facts or circumstances which lead it to believe that it will file for reorganization or liquidation under
the bankruptcy or reorganization laws of any jurisdiction within one year from the Closing Date. Schedule 3.1(aa) sets forth as
of the date hereof all outstanding secured and unsecured Indebtedness of the Company or any Subsidiary, or for which the Company or any
Subsidiary has commitments. For the purposes of this Agreement, “Indebtedness” means (x) any liabilities for borrowed
money or amounts owed in excess of $50,000 (other than trade accounts payable incurred in the ordinary course of business), (y) all guaranties,
endorsements and other contingent obligations in respect of indebtedness of others, whether or not the same are or should be reflected
in the Company’s consolidated balance sheet (or the notes thereto), except guaranties by endorsement of negotiable instruments for
deposit or collection or similar transactions in the ordinary course of business; and (z) the present value of any lease payments in excess
of $50,000 due under leases required to be capitalized in accordance with GAAP. Neither the Company nor any Subsidiary is in default with
respect to any Indebtedness.

Documents and the transactions contemplated thereby. The Company further acknowledges that no Purchaser is 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 thereby

and the transactions contemplated thereby is merely incidental to the Purchasers’ purchase of the Securities. The Company further

with respect to Securities are being determined, and (z) such hedging activities (if any) could reduce the value of the existing stockholders'
equity interests in the Company at and after the time that the hedging activities are being conducted.  The Company acknowledges
that such aforementioned hedging activities do not constitute a breach of any of the Transaction Documents.

date therein, in which case they shall be accurate as of such date):


(a)            
Organization; Authority. Such Purchaser is either an individual or an entity duly incorporated
or formed, validly existing and in good standing under the laws of the jurisdiction of its incorporation or formation with full right,
corporate, partnership, limited liability company or similar power and authority to enter into and to consummate the transactions contemplated
by the Transaction Documents and otherwise to carry out its obligations hereunder and thereunder. The execution and delivery of the Transaction
Documents and performance by such Purchaser of the transactions contemplated by the Transaction Documents have been duly authorized by
all necessary corporate, partnership, limited liability company or similar action, as applicable, on the part of such Purchaser. Each
Transaction Document to which it is a party has been duly executed by such Purchaser, and when delivered by such Purchaser in accordance
with the terms hereof, will constitute the valid and legally binding obligation of such Purchaser, enforceable against it in accordance
with its terms, except: (i) as limited by general equitable principles and applicable bankruptcy, insolvency, reorganization, moratorium
and other laws of general application affecting enforcement of creditors’ rights generally, (ii) as limited by laws relating to
the availability of specific performance, injunctive relief or other equitable remedies and (iii) insofar as indemnification and contribution
provisions may be limited by applicable law.






    	16 



    	 



    

(b)            
Understandings or Arrangements. Such Purchaser is acquiring the Securities as principal for
its own account and has no direct or indirect arrangement or understandings with any other persons to distribute or regarding the distribution
of such Securities (this representation and warranty not limiting such Purchaser’s right to sell the Securities pursuant to the
Registration Statement or otherwise in compliance with applicable federal and state securities laws). Such Purchaser is acquiring the
Securities hereunder in the ordinary course of its business.


(c)            
Purchaser Status. At the time such Purchaser was offered the Securities, it was, and as of
the date hereof it is, and on each date on which it exercises any Warrants, it will be an “accredited investor” as defined
in Rule 501(a)(1), (a)(2), (a)(3), (a)(7), (a)(8), (a)(9), (a)(12), or (a)(13) under the Securities Act. 


(d)            
Experience of Such Purchaser. Such Purchaser, either alone or together with its representatives,
has such knowledge, sophistication and experience in business and financial matters so as to be capable of evaluating the merits and risks
of the prospective investment in the Securities, and has so evaluated the merits and risks of such investment. Such Purchaser is able
to bear the economic risk of an investment in the Securities and, at the present time, is able to afford a complete loss of such investment.


(e)            
Access to Information. Such Purchaser acknowledges that it has had the opportunity to review
the Transaction Documents (including all exhibits and schedules thereto) and the SEC Reports and has been afforded, (i) the opportunity
to ask such questions as it has deemed necessary of, and to receive answers from, representatives of the Company concerning the terms
and conditions of the offering of the Securities and the merits and risks of investing in the Securities; (ii) access to information about
the Company and its financial condition, results of operations, business, properties, management and prospects sufficient to enable it
to evaluate its investment; and (iii) the opportunity to obtain such additional information that the Company possesses or can acquire
without unreasonable effort or expense that is necessary to make an informed investment decision with respect to the investment. 
Such Purchaser acknowledges and agrees that neither the Placement Agent nor any Affiliate of the Placement Agent has provided such Purchaser
with any information or advice with respect to the Securities nor is such information or advice necessary or desired.  Neither the
Placement Agent nor any Affiliate has made or makes any representation as to the Company or the quality of the Securities and the Placement
Agent and any Affiliate may have acquired non-public information with respect to the Company which such Purchaser agrees need not be provided
to it.  In connection with the issuance of the Securities to such Purchaser, neither the Placement Agent nor any of its Affiliates
has acted as a financial advisor or fiduciary to such Purchaser.


The Company acknowledges
and agrees that the representations contained in this Section 3.2 shall not modify, amend or affect such Purchaser’s right to rely
on the Company’s representations and warranties contained in this Agreement or any representations and warranties contained in any
other Transaction Document or any other document or instrument executed and/or delivered in connection with this Agreement or the consummation
of the transactions contemplated hereby. Notwithstanding the foregoing, for the avoidance of doubt, nothing contained herein shall constitute
a representation or warranty, or preclude any actions, with respect to locating or borrowing shares in order to effect Short Sales or
similar transactions in the future.

ARTICLE IV.

OTHER AGREEMENTS OF THE PARTIES


4.1           
Warrant Shares. 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 Purchaser 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 during the term of the Warrants. 


4.2           
Furnishing of Information. Until the earliest of the time that (i) no Purchaser owns Securities
or (ii) the Warrants have expired, the Company covenants to timely file (or obtain extensions in respect thereof and file within the applicable
grace period) all reports required to be filed by the Company after the date hereof pursuant to the Exchange Act even if the Company is
not then subject to the reporting requirements of the Exchange Act. 


4.3           
Integration. The Company shall not sell, offer for sale or solicit offers to buy or otherwise
negotiate in respect of any security (as defined in Section 2 of the Securities Act) that would be integrated with the offer or sale of
the Securities for purposes of the rules and regulations of any Trading Market such that it would require shareholder approval prior to
the closing of such other transaction unless shareholder approval is obtained before the closing of such subsequent transaction. 


4.4           
Securities Laws Disclosure; Publicity. The Company shall (a) by the Disclosure Time, issue
a press release disclosing the material terms of the transactions contemplated hereby, and (b) file a Current Report on Form 8-K, including
the Transaction Documents as exhibits thereto, with the Commission within the time required by the Exchange Act. From and after the issuance
of such press release, the Company represents to the Purchasers that it shall have publicly disclosed all material, non-public information
delivered to any of the Purchasers by the Company or any of its Subsidiaries, or any of their respective officers, directors, employees,
Affiliates or agents, including, without limitation, the Placement Agent, in connection with the transactions contemplated by the Transaction
Documents. In addition, effective upon the issuance of such press release, 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, Affiliates or agents, including, without limitation, the Placement Agent, on the one hand, and
any of the Purchasers or any of their Affiliates on the other hand, shall terminate and be of no further force or effect. The Company
understands and confirms that each Purchaser shall be relying on the foregoing covenant in effecting transactions in securities of the
Company. The Company and each Purchaser shall consult with each other in issuing any other press releases with respect to the transactions
contemplated hereby, and neither the Company nor any Purchaser shall issue any such press release nor otherwise make any such public statement
without the prior consent of the Company, with respect to any press release of any Purchaser, or without the prior consent of each Purchaser,
with respect to any press release of the Company, which consent shall not unreasonably be withheld or delayed, except if such disclosure
is required by law, in which case the disclosing party shall promptly provide the other party with prior notice of such public statement
or communication. Notwithstanding the foregoing, the Company shall not publicly disclose the name of any Purchaser, or include the name
of any Purchaser in any filing with the Commission or any regulatory agency or Trading Market, without the prior written consent of such
Purchaser, except (a) as required by federal securities law in connection with the filing of final Transaction Documents with the Commission
and (b) to the extent such disclosure is required by law or Trading Market regulations, in which case the Company shall provide the Purchasers
with prior notice of such disclosure permitted under this clause (b) and reasonably cooperate with such Purchaser regarding such disclosure.

4.5           
Shareholder Rights Plan. No claim will be made or enforced by the Company or, with the consent
of the Company, any other Person, that any Purchaser 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 Purchaser 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 Purchasers.


4.6           
Non-Public Information. Except with respect to the material pricing terms and conditions of
the transactions contemplated by the Transaction Documents, which shall be disclosed pursuant to Section 4.4, the Company covenants and
agrees that neither it, nor any other Person acting on its behalf will provide any Purchaser or its agents or counsel with any information
that constitutes, or the Company reasonably believes constitutes, material non-public information, unless prior thereto such Purchaser
shall have consented in writing to the receipt of such information and agreed in writing with the Company to keep such information confidential.
The Company understands and confirms that each Purchaser shall be relying on the foregoing covenant in effecting transactions in securities
of the Company. To the extent that the Company, any of its Subsidiaries, or any of their respective officers, directors, agents, employees
or Affiliates delivers any material, non-public information to a Purchaser without such Purchaser’s consent, the Company hereby
covenants and agrees that such Purchaser shall not have any duty of confidentiality to the Company, any of its Subsidiaries, or any of
their respective officers, directors, employees, Affiliates or agents, including, without limitation, the Placement Agent, or a duty to
the Company, any of its Subsidiaries or any of their respective officers, directors, employees, Affiliates or agents, including, without
limitation, the Placement Agent, not to trade on the basis of, such material, non-public information, provided that the Purchaser shall
remain subject to applicable law. To the extent that any notice provided pursuant to any Transaction Document constitutes, or contains,
material, non-public information regarding the Company or any Subsidiaries, the Company shall simultaneously with the delivery of such
notice file such notice with the Commission pursuant to a Current Report on Form 8-K. The Company understands and confirms that each Purchaser
shall be relying on the foregoing covenant in effecting transactions in securities of the Company.


4.7           
Use of Proceeds. The Company shall use the net proceeds from the sale of the Securities hereunder
for the purposes set forth in the Pricing Prospectus and Prospectus and, except as set forth on Schedule 4.7 attached hereto, shall
not use such proceeds: (a) for the satisfaction of any portion of the Company’s debt (other than payment of trade payables in the
ordinary course of the Company’s business and prior practices), (b) for the redemption of any Common Stock or Common Stock Equivalents,
(c) for the settlement of any outstanding litigation or (d) in violation of FCPA or OFAC regulations.


4.8           
Indemnification of Purchasers. Subject to the provisions of this Section 4.8, the Company
will indemnify and hold each Purchaser and its directors, officers, shareholders, members, partners, employees and agents (and any other
Persons with a functionally equivalent role of a Person holding such titles notwithstanding a lack of such title or any other title),
each Person who controls such Purchaser (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and
the directors, officers, shareholders, agents, members, partners or employees (and any other Persons with a functionally equivalent role
of a Person holding such titles notwithstanding a lack of such title or any other title) of such controlling persons (each, a “Purchaser
Party”) harmless from any and all losses, liabilities, obligations, claims, contingencies, damages, costs and expenses, including
all judgments, amounts paid in settlements, court costs and reasonable attorneys’ fees and costs of investigation that any such
Purchaser Party may suffer or incur as a result of or relating to (a) any breach of any of the representations, warranties, covenants
or agreements made by the Company in this Agreement or in the other Transaction Documents or (b) any action instituted against the Purchaser
Parties in any capacity, or any of them or their respective Affiliates, by any stockholder of the Company who is not an Affiliate of such
Purchaser Party, with respect to any of the transactions contemplated by the Transaction Documents (unless such action is solely based
upon a material breach of such Purchaser Party’s representations, warranties or covenants under the Transaction Documents or any
agreements or understandings such Purchaser Party may have with any such stockholder or any violations by such Purchaser Party of state
or federal securities laws or any conduct by such Purchaser Party which is finally judicially determined to constitute fraud, gross negligence
or willful misconduct). If any action shall be brought against any Purchaser Party in respect of which indemnity may be sought pursuant
to this Agreement, such Purchaser Party 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 Purchaser Party. Any Purchaser Party 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 Purchaser Party 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 counsel a material conflict on any material issue between the position
of the Company and the position of such Purchaser Party, in which case the Company shall be responsible for the reasonable fees and expenses
of no more than one such separate counsel. The Company will not be liable to any Purchaser Party under this Agreement (y) for any settlement
by a Purchaser Party effected without the Company’s prior written consent, which shall not be unreasonably withheld or delayed;
or (z) to the extent, but only to the extent that a loss, claim, damage or liability is attributable to any Purchaser Party’s breach
of any of the representations, warranties, covenants or agreements made by such Purchaser Party in this Agreement or in the other Transaction
Documents. The indemnification required by this Section 4.8 shall be made by periodic payments of the amount thereof during the course
of the investigation or defense, as and when bills are received or are incurred. The indemnity agreements contained herein shall be in
addition to any cause of action or similar right of any Purchaser Party against the Company or others and any liabilities the Company
may be subject to pursuant to law.

4.9           
Reservation of Common Stock. As of the date hereof, the Company has reserved and the Company
shall continue to reserve and keep available at all times, free of preemptive rights, a sufficient number of shares of Common Stock for
the purpose of enabling the Company to issue Shares pursuant to this Agreement and Warrant Shares pursuant to any exercise of the Warrants.


4.10        
Listing of Common Stock. The Company hereby agrees to use best efforts to maintain the listing
or quotation of the Common Stock on the Trading Market on which it is currently listed, and concurrently with the Closing, the Company
shall apply to list or quote all of the Shares and Warrant Shares on such Trading Market and promptly secure the listing of all of the
Shares and Warrant Shares on such Trading Market. The Company further agrees, if the Company applies to have the Common Stock traded on
any other Trading Market, it will then include in such application all of the Shares and Warrant Shares, and will take such other action
as is necessary to cause all of the Shares and Warrant Shares to be listed or quoted on such other Trading Market as promptly as possible.
The Company will then take all action reasonably necessary to continue the listing and trading of its Common Stock on a Trading Market
and will comply in all respects with the Company’s reporting, filing and other obligations under the bylaws or rules of the Trading
Market. The Company agrees to maintain the eligibility of the Common Stock for electronic transfer through the Depository Trust Company
or another established clearing corporation, including, without limitation, by timely payment of fees to the Depository Trust Company
or such other established clearing corporation in connection with such electronic transfer.


4.11        
Subsequent Equity Sales. 


(a)            
From the date hereof until sixty (60) days after the Closing Date, neither the Company nor any Subsidiary
shall (i) issue, enter into any agreement to issue or announce the issuance or proposed issuance of any shares of Common Stock or Common
Stock Equivalents or (ii) file any registration statement or amendment or supplement thereto, other than the Prospectus or filing a registration
statement on Form S-8 in connection with any employee benefit plan.


(b)            
From the date hereof until the one (1) year anniversary of the Closing Date, 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 (i) 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 (A) 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 (B) 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 (ii) enters into,
or effects a transaction under, any agreement, including, but not limited to, an equity line of credit or an “at-the-market offering”,
whereby the Company may issue securities at a future determined price regardless of whether shares pursuant to such agreement have actually
been issued and regardless of whether such agreement is subsequently canceled; provided, however, that, after sixty (60)
days following the Closing Date, the issuance of shares of Common Stock in an “at the market” offering with H.C. Wainwright
& Co., LLC as sales agent shall not be deemed a Variable Rate Transaction. Any Purchaser shall be entitled to obtain injunctive relief
against the Company to preclude any such issuance, which remedy shall be in addition to any right to collect damages. 


(c)            
Notwithstanding the foregoing, this Section 4.11 shall not apply in respect of an Exempt Issuance,
except that no Variable Rate Transaction shall be an Exempt Issuance.

4.12        
Equal Treatment of Purchasers. No consideration (including any modification of this Agreement)
shall be offered or paid to any Person to amend or consent to a waiver or modification of any provision of this Agreement unless the same
consideration is also offered to all of the parties to this Agreement. For clarification purposes, this provision constitutes a separate
right granted to each Purchaser by the Company and negotiated separately by each Purchaser, and is intended for the Company to treat the
Purchasers as a class and shall not in any way be construed as the Purchasers acting in concert or as a group with respect to the purchase,
disposition or voting of Securities or otherwise.


4.13        
[RESERVED]


4.14        
Capital Changes. Until the one year anniversary of the Closing Date, the Company shall not
undertake a reverse or forward stock split or reclassification of the Common Stock without the prior written consent of the Purchasers
holding a majority in interest of the Shares and Prefunded Warrants, other than a reverse stock split that is required, in the good faith
determination of the Board of Directors, to maintain the listing of the Common Stock on the Trading Market.


4.15        
Exercise Procedures. The form of Notice of Exercise included in the Warrants
set forth the totality of the procedures required of the Purchasers in order to exercise the Warrants. No additional legal opinion, other
information or instructions shall be required of the Purchasers to exercise their Warrants. Without limiting the preceding sentences,
no ink-original Notice of Exercise shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of
any Notice of Exercise form be required in order to exercise the Warrants. The Company shall honor exercises of the Warrants and shall
deliver Warrant Shares in accordance with the terms, conditions and time periods set forth in the Transaction Documents.


4.16        
Lock-Up Agreements. The Company shall not amend, modify, waive or terminate any provision
of any of the Lock-Up Agreements except to extend the term of the lock-up period and shall enforce the provisions of each Lock-Up Agreement
in accordance with its terms. If any party to a Lock-Up Agreement breaches any provision of a Lock-Up Agreement, the Company shall promptly
use its best efforts to seek specific performance of the terms of such Lock-Up Agreement.

Action or Proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such
party at the address in effect for 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 process in any
other manner permitted by law. If any party shall commence an Action or Proceeding to enforce any provisions of the Transaction Documents,
then, in addition to the obligations of the Company under Section 4.8, the prevailing party in such Action or Proceeding shall be reimbursed
by the non-prevailing party for its reasonable attorneys’ fees and other costs and expenses incurred with the investigation, preparation
and prosecution of such Action or Proceeding.

5.10        
Survival. The representations and warranties contained herein shall survive the Closing and
the delivery of the Securities.


5.11        
Execution. This Agreement may be executed in two or more counterparts, all of which when taken
together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and
delivered to each other party, it being understood that the parties need not sign the same counterpart. In the event that any signature
is delivered by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of
the party executing (or on whose behalf such signature is executed) with the same force and effect as if such “.pdf” signature
page were an original thereof.


5.12        
Severability. If any term, provision, covenant or restriction of this Agreement is held by
a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and
restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the
parties hereto shall use their commercially reasonable efforts to find and employ an alternative means to achieve the same or substantially
the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the
intention of the parties that they would have executed the remaining terms, provisions, covenants and restrictions without including any
of such that may be hereafter declared invalid, illegal, void or unenforceable.


5.13        
Rescission and Withdrawal Right. Notwithstanding anything to the contrary contained in (and
without limiting any similar provisions of) any of the other Transaction Documents, whenever any Purchaser exercises a right, election,
demand or option under a Transaction Document and the Company does not timely perform its related obligations within the periods therein
provided, then such Purchaser may rescind or withdraw, in its sole discretion from time to time upon written notice to the Company, any
relevant notice, demand or election in whole or in part without prejudice to its future actions and rights; provided, however,
that, in the case of a rescission of an exercise of a Warrant, the applicable Purchaser shall be required to return any shares of Common
Stock subject to any such rescinded exercise notice concurrently with the return to such Purchaser of the aggregate exercise price paid
to the Company for such shares and the restoration of such Purchaser’s right to acquire such shares pursuant to such Purchaser’s
Warrant (including, issuance of a replacement warrant certificate evidencing such restored right).


5.14        
Replacement of Securities. If any certificate or instrument evidencing any Securities is mutilated,
lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof
(in the case of mutilation), or in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of evidence
reasonably satisfactory to the Company of such loss, theft or destruction. The applicant for a new certificate or instrument under such
circumstances shall also pay any reasonable third-party costs (including customary indemnity) associated with the issuance of such replacement
Securities.


5.15        
Remedies. In addition to being entitled to exercise all rights provided herein or granted
by law, including recovery of damages, each of the Purchasers and the Company will be entitled to specific performance under the Transaction
Documents. The parties agree that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations
contained in the Transaction Documents and hereby agree to waive and not to assert in any Action for specific performance of any such
obligation the defense that a remedy at law would be adequate.

5.16        
Payment Set Aside. To the extent that the Company makes a payment or payments to any Purchaser
pursuant to any Transaction Document or a Purchaser enforces or exercises its rights thereunder, and such payment or payments or the proceeds
of such enforcement or exercise or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside,
recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any other
Person under any law (including, without limitation, any bankruptcy law, state or federal law, common law or equitable cause of action),
then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued
in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred.


5.17        
Independent Nature of Purchasers’ Obligations and Rights. The obligations of each Purchaser
under any Transaction Document are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible
in any way for the performance or non-performance of the obligations of any other Purchaser under any Transaction Document. Nothing contained
herein or in any other Transaction Document, and no action taken by any Purchaser pursuant hereto or thereto, shall be deemed to constitute
the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers
are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Documents.
Each Purchaser shall be entitled to independently protect and enforce its rights including, without limitation, the rights arising out
of this Agreement or out of the other Transaction Documents, and it shall not be necessary for any other Purchaser to be joined as an
additional party in any Proceeding for such purpose. Each Purchaser has been represented by its own separate legal counsel in its review
and negotiation of the Transaction Documents. For reasons of administrative convenience only, each Purchaser and its respective counsel
have chosen to communicate with the Company through EGS. EGS does not represent any of the Purchasers and only represents the Placement
Agent. The Company has elected to provide all Purchasers with the same terms and Transaction Documents for the convenience of the Company
and not because it was required or requested to do so by any of the Purchasers. It is expressly understood and agreed that each provision
contained in this Agreement and in each other Transaction Document is between the Company and a Purchaser, solely, and not between the
Company and the Purchasers collectively and not between and among the Purchasers.


5.18        
Liquidated Damages. The Company’s obligations to pay any partial liquidated damages
or other amounts owing under the Transaction Documents is a continuing obligation of the Company and shall not terminate until all unpaid
partial liquidated damages and other amounts have been paid notwithstanding the fact that the instrument or security pursuant to which
such partial liquidated damages or other amounts are due and payable shall have been canceled.


5.19        
Saturdays, Sundays, Holidays, etc.If the last or appointed day for the taking of any action
or the expiration of any right required or granted herein shall not be a Business Day, then such action may be taken or such right may
be exercised on the next succeeding Business Day.


5.20        
Construction. The parties agree that each of them and/or their respective counsel have reviewed
and had an opportunity to revise the Transaction Documents and, therefore, the normal rule of construction to the effect that any ambiguities
are to be resolved against the drafting party shall not be employed in the interpretation of the Transaction Documents or any amendments
thereto. In addition, each and every reference to share prices and shares of Common Stock in any Transaction Document shall be subject
to adjustment for reverse and forward stock splits, stock dividends, stock combinations and other similar transactions of the Common Stock
that occur after the date of this Agreement.


5.21        
WAIVER OF JURY TRIAL. IN ANY ACTION, SUIT, OR PROCEEDING IN ANY JURISDICTION BROUGHT
BY ANY PARTY AGAINST ANY OTHER PARTY, THE PARTIES EACH KNOWINGLY AND INTENTIONALLY, TO THE GREATEST EXTENT PERMITTED BY APPLICABLE LAW,
HEREBY ABSOLUTELY, UNCONDITIONALLY, IRREVOCABLY AND EXPRESSLY WAIVES FOREVER TRIAL BY JURY.
