2.1          Closing.
On the Closing Date, upon the terms and subject to the conditions set forth herein, the Company agrees to sell, and the Purchasers,
severally and not jointly, agree to purchase, up to an aggregate of approximately $35.0 million of Class A Units as determined
pursuant to Section 2.2(a); provided, however, that, to the extent that a Purchaser determines, in its sole discretion, that
such Purchaser (together with such Purchaser’s Affiliates, and any Person acting as a group together with such purchaser
or any of such Purchaser’s Affiliates) would beneficially own in excess of the Beneficial Ownership Limitation, or as such
Purchaser may otherwise choose, in lieu of purchasing Class A Units such Purchaser may elect to purchase Class B Units
at the Class B Unit Purchase Price in lieu of Class A Units in such manner to result in the same aggregate purchase price
being paid by such Purchaser to the Company. The “Beneficial Ownership Limitation” shall be 9.99% (or, at the election
of the Purchaser, 4.99%) of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance
of the Securities on the Closing Date. Each Purchaser’s Subscription Amount as set forth on the signature page hereto
executed by such Purchaser shall be made available for “Delivery Versus Payment” (“DVP”) settlement
with the Company or its designees. The Company shall deliver to each Purchaser its respective Shares or Pre-Funded Warrants (as
applicable to such Purchaser) and Series A Warrants as determined pursuant to Section 2.2(a), and the Company and each
Purchaser shall deliver the other items set forth in Section 2.2 deliverable at the Closing. Upon satisfaction of the covenants
and conditions set forth in Sections 2.2 and 2.3, the Closing shall occur at the offices of the Placement Agent or such other location
as the parties shall mutually agree. The Company covenants that, if the Purchaser delivers a Notice of Exercise (as defined in
the Pre-Funded Warrant) no later than 12:00 p.m. (New York City time) on the Closing Date to exercise any Pre-Funded Warrants
between the date hereof and the Closing Date, the Company shall deliver Pre-Funded Warrant Shares to the Purchaser on the Closing
Date in connection with such Notice of Exercise. Unless otherwise directed by the Placement Agent, settlement of the Shares shall
occur via DVP (i.e., on the Closing Date, the Company shall issue the Shares registered in the Purchasers’ names and addresses
and released by the Transfer Agent directly to the account(s) at the Placement Agent identified by each Purchaser; upon receipt
of such Shares, the Placement Agent shall promptly electronically deliver such Shares to the applicable Purchaser, and payment
therefor shall be made by the Placement Agent (or its clearing firm) by wire transfer to the Company).

Permits. The Company and the Subsidiaries possess all certificates, authorizations and permits issued by the appropriate federal,
state, local or foreign regulatory authorities necessary to conduct their respective businesses as described in the SEC Reports,

Permits”), and neither the Company nor any Subsidiary has received any notice of proceedings relating to the revocation
or modification of any Material Permit.


 


(o)          Title
to Assets. The Company and the Subsidiaries have good and marketable title in fee simple to all real property owned by them
and good and marketable title in all personal property owned by them that is material to the business of the Company and the Subsidiaries,
in each case free and clear of all Liens, except for (i) Liens as do not materially affect the value of such property and
do not materially interfere with the use made and proposed to be made of such property by the Company and the Subsidiaries, and
(ii) Liens for the payment of federal, state or other taxes, for which appropriate reserves have been made therefor in accordance
with GAAP and, the payment of which is neither delinquent nor subject to penalties. Any real property and facilities held under

statements included within the SEC Reports, a written notice of a claim or otherwise has any knowledge that the Intellectual Property
Rights violate or infringe upon the rights of any Person, except as could not have or reasonably be expected to not have a Material
Adverse Effect. To the knowledge of the Company, all such Intellectual Property Rights are enforceable and there is no existing
infringement by another Person of any of the Intellectual Property Rights. The Company and its Subsidiaries have taken reasonable
security measures to protect the secrecy, confidentiality and value of all of their intellectual properties, except where failure
to do so could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. The Company has
no knowledge of any facts that would preclude it from having valid license rights or clear title to the Intellectual Property Rights.
The Company has no knowledge that it lacks or will be unable to obtain any rights or licenses to use all Intellectual Property
Rights that are necessary to conduct its business.

a significant increase in cost.

the Sarbanes-Oxley Act of 2002 that are effective as of the date hereof, and any and all applicable rules and regulations
promulgated by the Commission thereunder that are effective as of the date hereof and as of the Closing Date. The Company and the

are executed in accordance with management’s general or specific authorizations, (ii) transactions are recorded as necessary
to permit preparation of financial statements in conformity with GAAP and to maintain asset accountability, (iii) access to
assets is permitted only in accordance with management’s general or specific authorization, and (iv) the recorded accountability

and reported, within the time periods specified in the Commission’s rules and forms. The Company’s certifying
officers have evaluated the effectiveness of the disclosure controls and procedures of the Company and the Subsidiaries as of the
end of the period covered by the most recently 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

terminating such registration. The Company has not, in the 12 months preceding the date hereof, received notice from 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

electronic transfer.

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.

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 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

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.

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.

Status. Except for matters that would not, individually or in the aggregate, have or reasonably be expected to result in a

local income and all foreign income and franchise tax returns, reports and declarations required by any jurisdiction to which it
is subject, (ii) 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 and (iii) has set aside on its books provision reasonably adequate for
the payment of all material taxes for periods subsequent to the periods to which such returns, reports or declarations apply. There
are no unpaid taxes in any material amount claimed to be due by the taxing authority of any jurisdiction, and the officers of the
Company or of any Subsidiary know of no basis for any such claim.


 


(cc)         Foreign
Corrupt Practices. Neither the Company nor any Subsidiary, nor to the knowledge of the Company or any Subsidiary, any agent

any unlawful payment to foreign or domestic government officials or employees or to any foreign or domestic political parties or
campaigns from corporate funds, (iii) failed to disclose fully any contribution made by the Company or any Subsidiary (or

material respect any provision of FCPA.

accounting firm (i) is a registered public accounting firm as required by the Exchange Act and (ii) shall express its
opinion with respect to the financial statements to be included in the Company’s Annual Report for the fiscal year ending

Regarding Purchasers’ Purchase of Securities. The Company acknowledges and agrees that each of the Purchasers is acting
solely in the capacity of an arm’s length purchaser with respect to the Transaction 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 any advice given
by any Purchaser or any of their respective representatives or agents in connection with the Transaction Documents and the transactions
contemplated thereby is merely incidental to the Purchasers’ purchase of the Securities. The Company further represents

short, securities of the Company, or “derivative” securities based on securities issued by the Company or to hold
the Securities for any specified term; (ii) past or future open market or other transactions by any Purchaser, specifically
including, without limitation, Short Sales or “derivative” transactions, before or after the closing of this or future
private placement transactions, may negatively impact the market price of the Company’s publicly-traded securities; (iii) any
Purchaser, and counter-parties in “derivative” transactions to which any such Purchaser is a party, directly or indirectly,
presently may have a “short” position in the Common Stock, and (iv) each Purchaser shall not be deemed to have
any affiliation with or control over any arm’s length counter-party in any “derivative” transaction. The Company
further understands and acknowledges that (y) one or more Purchasers may engage in hedging activities at various times during
the period that the Securities are outstanding, including, without limitation, during the periods that the value of the Warrant
Shares deliverable 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.


 


(gg)        Regulation
M Compliance.  The Company has not, and to its knowledge no one acting on its behalf has, (i) taken, directly or
indirectly, any action designed to cause or to result in the stabilization or manipulation of the price of any security of the
Company to facilitate the sale or resale of any of the Securities, (ii) sold, bid for, purchased, or, paid any compensation
for soliciting purchases of, any of the Securities, or (iii) paid or agreed to pay to any Person any compensation for soliciting
another to purchase any other securities of the Company, other than, in the case of clauses (ii) and (iii), compensation paid
to the Company’s placement agent in connection with the placement of the Securities.

3.2            Representations
and Warranties of the Purchasers. Each Purchaser, for itself and for no other Purchaser, hereby represents and warrants as
of the date hereof and as of the Closing Date to the Company as follows (unless as of a specific 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.


 






    22


    


    

 


(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 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 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.


 






    23


    


    

 


(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 or any other Person representing the Company setting
forth the material 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 Securities 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          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.


 






    24


    


    

 


4.2            Furnishing
of Information. Until the earlier of the time that (i) no Purchaser owns Securities and (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 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, 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).


 






    25


    


    

 


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 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
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 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.


 


4.7            Use
of Proceeds. Except as set forth on Schedule 4.7 attached hereto, the Company shall use the net proceeds from the sale
of the Securities 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.

4.8            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 (x) the employment thereof has been specifically authorized by the Company in writing, (y) the Company has
failed after a reasonable period of time to assume such defense and to employ counsel or (z) 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 (1) for any settlement by a Purchaser
Party effected without the Company’s prior written consent, which shall not be unreasonably withheld or delayed; or (2) 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.

4.12          Subsequent
Equity Sales.


 


(a)            From
the date hereof until 90 days after the Closing Date, neither the Company nor any Subsidiary shall issue, enter into any agreement
to issue or announce the issuance or proposed issuance of any shares of Common Stock or Common Stock Equivalents.


 


(b)            Notwithstanding
the foregoing, this Section 4.12 shall not apply in respect of an Exempt Issuance.


 


4.13          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.


 


4.14         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 4.4.  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 4.4, 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 4.4, (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 4.4 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 4.4.  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 Securities covered
by this Agreement.


 






    28


    


    

 


4.15         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.


 


4.16          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.


 


ARTICLE V.

5.1           Termination. 
This Agreement may be terminated 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, if 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).

5.5            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 at least 50.1% in interest of the sum of (i) the
Shares and (ii) the Pre-Funded Warrant Shares initially issuable upon exercise of the Pre-Funded Warrants based on the initial
Subscription Amounts 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 at least 50.1% in interest 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 Securities and the Company.

to the transferred Securities, by the provisions of the Transaction Documents that apply to the “Purchasers.”

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

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; 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.


 






    32


    


    

 


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 the legal counsel of the Placement Agent.
The legal counsel of the Placement Agent 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.


 






    33


    


    

 


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.
