agree to purchase, an aggregate of $15,023,000 of Shares. Each Purchaser’s Subscription Amount as set forth on the signature

Unless otherwise directed by the Placement Agent, settlement of the Shares shall occur via “Delivery Versus Payment”

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

(x) any liabilities for borrowed money or amounts owed in excess of $100,000 (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

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.

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.


 






    21 


     


    

 


(b)              
Understandings or Arrangements. Such Purchaser is acquiring the Shares 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 Shares
(this representation and warranty not limiting such Purchaser’s right to sell the Shares pursuant to the Registration Statement
or otherwise in compliance with applicable federal and state securities laws). Such Purchaser is acquiring the Shares hereunder
in the ordinary course of its business.


 


(c)              
Purchaser Status. At the time such Purchaser was offered the Shares, it was, and as of the date hereof it is either:
(i) an “accredited investor” as defined in Rule 501(a)(1), (a)(2), (a)(3), (a)(7) or (a)(8) under the Securities Act
or (ii) a “qualified institutional buyer” as defined in Rule 144A(a) 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 Shares, 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 Shares 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 including the Disclosure Schedules) 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 Shares and the merits and risks of investing in the Shares; (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 Shares 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 Shares 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 Shares to such
Purchaser, neither the Placement Agent nor any of its Affiliates has acted as a financial advisor or fiduciary to such Purchaser.


 






    22 


     


    

 


(f)                Certain
Transactions and Confidentiality. Other than consummating the transactions contemplated hereunder, such Purchaser has
not, nor has any Person acting on behalf of or pursuant to any understanding with such Purchaser, directly or indirectly
executed any purchases or sales, including Short Sales, of the securities of the Company during the period commencing as
of the time that such Purchaser first received a term sheet (written or oral) from the Company, the Placement Agent or any
other Person representing the Company setting forth the material pricing terms of the transactions contemplated hereunder and
ending immediately prior to the execution hereof. Notwithstanding the foregoing, in the case of a Purchaser that is a
multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Purchaser’s
assets and the portfolio managers have no direct knowledge of the investment decisions made by the portfolio managers
managing other portions of such Purchaser’s assets, the representation set forth above shall only apply with respect to
the portion of assets managed by the portfolio manager that made the investment decision to purchase the Shares covered by
this Agreement. Other than to other Persons party to this Agreement or to such Purchaser’s representatives, including,
without limitation, its officers, directors, partners, legal and other advisors, employees, agents and Affiliates, such
Purchaser has maintained the confidentiality of all disclosures made to it in connection with this transaction (including the
existence and terms of this transaction). 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.


 


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             
Furnishing of Information. Until the time that no Purchaser owns Shares, 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.


 


4.2             
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 Shares 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.


 






    23 


     


    

 


4.3              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 or agents 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 or Affiliates on the one hand, and any of the
Purchasers or any of their Affiliates on the other hand, shall terminate. 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 (other than the press release described in the first sentence of this Section
4.3), 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, or if such disclosure is consistent with the Form 8-K.
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).


 






    24 


     


    

 



 


4.4             
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 Shares under the Transaction Documents or under any other agreement between the Company and the Purchasers.


 


4.5              Non-Public
Information. Except with respect to the material terms and conditions of the transactions contemplated by the Transaction
Documents, which shall be disclosed pursuant to Section 4.3, 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 to the receipt of such information and agreed 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, agents, employees or
Affiliates, or a duty to the Company, any of its Subsidiaries or any of their respective officers, directors, agents,
employees or Affiliates 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 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.


 






    25



     


    




 


4.6             
Use of Proceeds. Except as set forth on Schedule 4.6 attached hereto, the Company shall use the net proceeds
from the sale of the Shares hereunder for working capital purposes and 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.


 


4.7              Indemnification
of Purchasers. Subject to the provisions of this Section 4.7, 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 material 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,
actual and documented 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 4.7 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;
provided, however, that if it is subsequently determined by a final, non-appealable judgment of a court of competent
jurisdiction that a Purchaser Party was not entitled to receive such periodic payments, such Purchaser Party shall promptly
(but in no event later than five Business Days) return such payments to the Company. 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.


 






    26



     


    

 


4.8             
Listing of Common Stock. The Company hereby agrees to use commercially reasonable 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 on such Trading Market and promptly secure the listing of all of the 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 will take such other action as is necessary to cause all
of the 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.


 


4.9 
Subsequent Equity Sales.


 


(a)              
From the date hereof until ninety (90) 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; provided, however, that this Section 4.9(a)
shall not prohibit (a) the filing of the Prospectus Supplement or the filing of a registration statement or any amendment or supplement
thereto pursuant to the Registration Rights Agreement, dated October 7, 2020, by and between the Company and Dillon Hill Capital,
LLC or pursuant to the Registration Rights Agreement, dated October 7, 2020, by and between the Company and Dillon Hill Investment
Company, LLC, (b) the filing of any Annual Report on Form 10-K, Quarterly Report on Form 10-Q or Current Report on Form 8-K that
may be deemed to be an amendment or supplement to any existing registration statement or (c) the filing of any amendment or supplement
to any existing registration statement solely for the purpose of revising any required disclosure in such registration statement
and not for the purpose of increasing the offering size pursuant to any such registration statement.


 






    27


     


    

 


(b)              
Notwithstanding the foregoing, this Section 4.9 shall not apply in respect of an Exempt Issuance.


 


4.10         
Equal Treatment of Purchasers. 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 Document. 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 Shares or otherwise.


 


4.11         
Certain Transactions and Confidentiality. Each Purchaser, severally and not jointly with the other Purchasers, covenants
that neither it nor any Affiliate acting on its behalf or pursuant to any understanding with it will execute any purchases or sales,
including Short Sales of any of the Company’s securities during the period commencing with the execution of this Agreement
and ending at such time that the transactions contemplated by this Agreement are first publicly announced pursuant to the initial
press release as described in Section 4.3.  Each Purchaser, severally and not jointly
with the other Purchasers, covenants that until such time as the transactions contemplated by this Agreement are publicly disclosed
by the Company pursuant to the initial press release as described in Section 4.3, such Purchaser will maintain the confidentiality
of the existence and terms of this transaction and the information included in the Disclosure Schedules.  Notwithstanding
the foregoing and notwithstanding anything contained in this Agreement to the contrary, the Company expressly acknowledges and
agrees that (i) no Purchaser makes any representation, warranty or covenant hereby that it will not engage in effecting transactions
in any securities of the Company after the time that the transactions contemplated by this Agreement are first publicly announced
pursuant to the initial press release as described in Section 4.3, (ii) no Purchaser shall be restricted or prohibited from effecting
any transactions in any securities of the Company in accordance with applicable securities laws from and after the time that the
transactions contemplated by this Agreement are first publicly announced pursuant to the initial press release as described in
Section 4.3 and (iii) no Purchaser shall have any duty of confidentiality or duty not to trade in the securities of the Company
to the Company or its Subsidiaries after the issuance of the initial press release as described in Section 4.3.  Notwithstanding
the foregoing, in the case of a Purchaser that is a multi-managed investment vehicle whereby separate portfolio managers manage
separate portions of such Purchaser’s assets and the portfolio managers have no direct knowledge of the investment decisions
made by the portfolio managers managing other portions of such Purchaser’s assets, the covenant set forth above shall only
apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the
Shares covered by this Agreement.


 






    28


     


    

 


4.12         
 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.


 


ARTICLE V.

MISCELLANEOUS


 


5.1             
Termination.  This Agreement may be terminated (a) by any Purchaser, as to such Purchaser’s obligations
hereunder only and without any effect whatsoever on the obligations between the Company and the other Purchasers, by written notice
to the other parties or (b) the Company by written notice to the Purchasers,
if in either case the Closing has not been consummated on or before the fifth (5th) Trading Day following the date hereof;
provided, however, that no such termination will affect the right of any party to sue for any breach by any other
party (or parties).


 


5.2             
Fees and Expenses. Except as expressly set forth in the Transaction Documents to the contrary, each party shall pay
the fees and expenses of its advisers, counsel, accountants and other experts, if any, and all other expenses incurred by such
party incident to the negotiation, preparation, execution, delivery and performance of this Agreement. The Company shall pay all
Transfer Agent fees (including, without limitation, any fees required for same-day processing of any instruction letter delivered
by the Company), stamp taxes and other taxes and duties levied in connection with the delivery of any Shares to the Purchasers.


 


5.3             
Entire Agreement. The Transaction Documents, together with the exhibits and schedules thereto, the Prospectus and
the Prospectus Supplement, contain the entire understanding of the parties with respect to the subject matter hereof and thereof
and supersede all prior agreements and understandings, oral or written, with respect to such matters, which the parties acknowledge
have been merged into such documents, exhibits and schedules.


 


5.4             
Notices. Any and all notices or other communications or deliveries required or permitted to be provided hereunder
shall be in writing and shall be deemed given and effective on the earliest of: (a) the time of transmission, if such notice or
communication is delivered via facsimile at the facsimile number or email attachment at the email address as set forth on the signature
pages attached hereto at or prior to 5:30 p.m. (New York City time) on a Trading Day, (b) the next Trading Day after the time of

recognized overnight courier service or (d) upon actual receipt by the party to whom such notice is required to be given. The address

provided pursuant to any Transaction Document constitutes, or contains, material, non-public information regarding the Company
or any Subsidiaries, the Company shall simultaneously file such notice with the Commission pursuant to a Current Report on Form
8-K.


 






    29


     


    

 


5.5             
 Amendments; Waivers. 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 Purchasers which purchased (or, if prior to the Closing,
all of the Purchasers) at least 50.1% in interest of the Shares based on the initial Subscription Amounts (which shall include
all Purchasers with an initial Subscription Amount of at least $3 million for any waiver, modification, supplementation or amendment
to Section 4.9(a)) hereunder or, in the case of a waiver, by the party against whom enforcement of any such waived provision is
sought, provided that if any amendment, modification or waiver disproportionately and adversely impacts a Purchaser (or group of
Purchasers), the consent of such disproportionately impacted Purchaser (or group of Purchasers) shall also be required. 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 proposed
amendment or waiver that disproportionately, materially and adversely affects the rights and obligations of any Purchaser relative
to the comparable rights and obligations of the other Purchasers shall require the prior written consent of such adversely affected
Purchaser. Any amendment effected in accordance with this Section 5.5 shall be binding upon each Purchaser and holder of Shares
and the Company.


 


5.6             
Headings. The headings herein are for convenience only, do not constitute a part of this Agreement and shall not
be deemed to limit or affect any of the provisions hereof.


 


5.7             
Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their successors
and permitted assigns. The Company may not assign this Agreement or any rights or obligations hereunder without the prior written
consent of each Purchaser (other than by merger). Any Purchaser may assign any or all of its rights under this Agreement to any
Person to whom such Purchaser assigns or transfers any Shares, provided that such transferee agrees in writing to be bound, with
respect to the transferred Shares, by the provisions of the Transaction Documents that apply to the “Purchasers.”


 


5.8             
No Third-Party Beneficiaries. The Placement Agent shall be the third party beneficiary of the representations and
warranties of the Company in Section 3.1 and the representations and warranties of the Purchasers in Section 3.2. This Agreement
is intended for the benefit of the parties hereto and their respective successors and permitted assigns and is not for the benefit
of, nor may any provision hereof be enforced by, any other Person, except as otherwise set forth in Section 4.7 and this Section
5.8.


 






    30


     


    

 


5.9              Governing
Law. All questions concerning the construction, validity, enforcement and interpretation of the Transaction Documents
shall be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard
to the principles of conflicts of law thereof. Each party agrees that all legal Proceedings concerning the interpretations,
enforcement and defense of the transactions contemplated by this Agreement and any other Transaction Documents (whether
brought against a party hereto or its respective affiliates, directors, officers, shareholders, partners, members, employees
or agents) shall be commenced exclusively in the state and federal courts sitting in the City of New York. Each party hereby
irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in the City of New York, Borough of
Manhattan for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby
or discussed herein (including with respect to the enforcement of any of the Transaction Documents), and hereby irrevocably
waives, and agrees not to assert in any Action or Proceeding, any claim that it is not personally subject to the jurisdiction
of any such court, that such Action or Proceeding is improper or is an inconvenient venue for such Proceeding. Each party
hereby irrevocably waives personal service of process and consents to process being served in any such 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 4.7, 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 Shares.


 


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 facsimile transmission or 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 facsimile or “.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.


 






    31


     


    

 


5.14         
 Replacement of Shares. If any certificate or instrument evidencing any Shares 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 Shares.


 


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 seek 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         
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.


 


5.19         
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.


 


5.20         
WAIVER OF JURY TRIAL. IN ANY ACTION, SUIT, OR PROCEEDING IN ANY JURISDICTION BROUGHT BY ANY PARTY AGAINST ANY
OTHER PARTY UNDER THE TRANSACTION DOCUMENTS, 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.
