execution and delivery of this Agreement by the parties hereto, the Company agrees to sell, and the Purchasers, severally and not jointly,
agree to purchase, up to an aggregate of $_______ of Shares and Common Warrants; provided, however, that, to the extent

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 Shares such Purchaser may elect to purchase Prefunded
Warrants in lieu of Shares 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 4.99% (or, at the election of the Purchaser at Closing, 9.99%) 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” settlement with the Company or its designee. The Company shall deliver to each Purchaser its
respective Shares and 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 take place remotely by electronic transfer of the Closing documentation. Each Purchaser acknowledges that, concurrently
with the Closing and pursuant to the Prospectus, the Company may sell up to $____ of additional Shares and Warrants to purchasers not
party to this Agreement, less the aggregate Subscription Amount pursuant to this Agreement, and will issue to such purchasers such shares
of Common Stock and Common Warrants or Prefunded Warrants and Common Warrants in the same form and at the same Per Share Purchase Price.
Unless otherwise directed by the Placement Agent, settlement of the Shares shall occur via “Delivery Versus Payment” (“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). Notwithstanding anything herein to the contrary, if at any time on or
after the time of execution of this Agreement by the Company and an applicable Purchaser, through, and including the time immediately
prior to the Closing (the “Pre-Settlement Period”), such Purchaser sells to any Person all, or any portion, of the
Shares to be issued hereunder to such Purchaser at the Closing (collectively, the “Pre-Settlement Shares”), such Purchaser
shall, automatically hereunder (without any additional required actions by such Purchaser or the Company), be deemed to be unconditionally
bound to purchase, such Pre-Settlement Shares to such Purchaser at the Closing; provided, that the Company shall not be required to deliver
any Pre-Settlement Shares to such Purchaser prior to the Company’s receipt of the purchase price of such Pre-Settlement Shares
hereunder; and provided further that the Company hereby acknowledges and agrees that the forgoing shall not constitute a representation
or covenant by such Purchaser as to whether or not during the Pre-Settlement Period such Purchaser shall sell any shares of Common Stock
to any Person and that any such decision to sell any shares of Common Stock by such Purchaser shall solely be made at the time such Purchaser
elects to effect any such sale, if any. Notwithstanding the foregoing, with respect to any Notice(s) of Exercise (as defined in the Prefunded
Warrants) delivered on or prior to 12:00 p.m. (New York City time) on the Closing Date, which may be delivered at any time after the
time of execution of this Agreement, the Company agrees to deliver the Warrant Shares subject to such notice(s) by 4:00 p.m. (New York
City time) on the Closing Date and the Closing Date shall be the Warrant Share Delivery Date (as defined in the Prefunded Warrants) for
purposes hereunder.

of the Sarbanes-Oxley Act of 2002, as amended that are effective as of the date hereof, and any and all applicable rules and regulations

designed such disclosure controls and procedures to ensure that information required to be disclosed by the Company in the reports it

the Company has taken no action designed to, or which to its knowledge is likely to have the effect of, terminating the registration

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 or maintenance
requirements of such Trading Market. The Company is, and has no reason to believe that it will not in the foreseeable future continue
to be, in compliance with all such listing and maintenance requirements. The Common Stock is currently eligible for electronic transfer
through the Depository Trust Company or another established clearing corporation and the Company is current in payment of the fees to
the Depository Trust Company (or such other established clearing corporation) in connection with such electronic transfer.

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


 


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

No Integrated Offering. Assuming the accuracy of the Purchasers’ representations and warranties set forth in Section 3.2,
neither the Company, nor any of its Affiliates, nor any Person acting on its or their behalf has, directly or indirectly, made any offers
or sales of any security or solicited any offers to buy any security, under circumstances that would cause this offering of the Securities
to be integrated with prior offerings by the Company for purposes of any applicable shareholder approval provisions of any Trading Market
on which any of the securities of the Company are listed or designated.


 


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

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.

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 to each Purchaser that the Company’s
decision to enter into this Agreement and the other Transaction Documents has been based solely on the independent evaluation of the
transactions contemplated hereby by the Company and its representatives.

acknowledges that such aforementioned hedging activities do not constitute a breach of any of the Transaction Documents.

(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

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.


 






    20


     


    

 


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


 


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


 


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


 


(e)
Access to Information. Such Purchaser acknowledges that it has had the opportunity to review the Transaction Documents (including
all exhibits and schedules thereto) and the Registration Statement and the Preliminary Prospectus 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

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

OTHER AGREEMENTS OF THE PARTIES


 


4.1
Warrant Shares. If all or any portion of a Warrant is exercised at a time when there is an effective registration statement to
cover the issuance or resale of the Warrant Shares or if the Warrant is exercised via cashless exercise, the Warrant Shares issued pursuant
to any such exercise shall be issued free of all legends. If at any time following the date hereof the Registration Statement (or any
subsequent registration statement registering the sale or resale of the Warrant Shares) is not effective or is not otherwise available
for the sale or resale of the Warrant Shares, the Company shall immediately notify the holders of the Warrants in writing that such registration
statement is not then effective and thereafter shall promptly notify such holders when the registration statement is effective again
and available for the sale or resale of the Warrant Shares (it being understood and agreed that the foregoing shall not limit the ability
of the Company to issue, or any Purchaser to sell, any of the Warrant Shares in compliance with applicable federal and state securities
laws). The Company shall use best efforts to keep a registration statement (including the Registration Statement) registering the issuance
or resale of the Warrant Shares effective during the term of the Warrants.


 


4.2
Furnishing of Information. Until the earliest of the time that (i) no Purchaser owns Securities or (ii) the Warrants have expired,
the Company covenants to timely file (or obtain extensions in respect thereof and file within the applicable grace period) all reports

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.


 






    22


     


    

 


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


 


4.5
Shareholder Rights Plan. No claim will be made or enforced by the Company or, with the consent of the Company, any other Person,
that any Purchaser is an “Acquiring Person” under any control share acquisition, business combination, poison pill
(including any distribution under a rights agreement) or similar anti-takeover plan or arrangement in effect or hereafter adopted by
the Company, or that any Purchaser could be deemed to trigger the provisions of any such plan or arrangement, by virtue of receiving
Securities under the Transaction Documents or under any other agreement between the Company and the Purchasers.


 


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

4.7
Use of Proceeds. Except as set forth in the Pricing Prospectus and the Prospectus, 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.

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


 


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


 






    24


     


    

 


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


 


4.11
Subsequent Equity Sales.


 


(a)
From the date hereof until 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, other than the Prospectus or filing a registration statement on Form S-8 in connection
with any employee benefit plan.


 


(b)
From the date hereof until nine (9) months after the Closing Date, the Company shall be prohibited from effecting or entering into an
agreement to effect any issuance by the Company or any of its Subsidiaries of Common Stock or Common Stock Equivalents (or a combination
of units thereof) involving a Variable Rate Transaction. “Variable Rate Transaction” means a transaction in which
the Company (i) issues or sells any debt or equity securities that are convertible into, exchangeable or exercisable for, or include
the right to receive additional shares of Common Stock either (A) at a conversion price, exercise price or exchange rate or other price
that is based upon and/or varies with the trading prices of or quotations for the shares of Common Stock at any time after the initial
issuance of such debt or equity securities, or (B) with a conversion, exercise or exchange price that is subject to being reset at some
future date after the initial issuance of such debt or equity security or upon the occurrence of specified or contingent events directly
or indirectly related to the business of the Company or the market for the Common Stock or (ii) enters into, or effects a transaction
under, any agreement, including, but not limited to, an equity line of credit or an “at-the-market offering”, whereby the
Company may issue securities at a future determined price. Any Purchaser shall be entitled to obtain injunctive relief against the Company
to preclude any such issuance, which remedy shall be in addition to any right to collect damages.


 


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


 


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


 






    25


     


    

 


4.13
Exercise Procedures. The form of Notice of Exercise included in the Warrants set forth the totality of the procedures required
of the Purchasers in order to exercise the Warrants. No additional legal opinion, other information or instructions shall be required
of the Purchasers to exercise their Warrants. Without limiting the preceding sentences, no ink-original Notice of Exercise shall be required,
nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of Exercise form be required in order to
exercise the Warrants. The Company shall honor exercises of the Warrants and shall deliver Warrant Shares in accordance with the terms,
conditions and time periods set forth in the Transaction Documents.


 


4.14
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.

Warrants based on the initial Subscription Amounts hereunder (or, prior to the Closing, the Company and each Purchaser) 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

Governing Law. All questions concerning the construction, validity, enforcement and interpretation of the Transaction Documents

5.11
Execution. This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered one

it being understood that the parties need not sign the same counterpart. In the event that any signature is delivered by e-mail delivery
of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party executing (or on whose
behalf such signature is executed) with the same force and effect as if such “.pdf” signature page were an original thereof.

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).

the Company of such loss, theft or destruction. The applicant for a new certificate or instrument under such circumstances shall also

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


 


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


 


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

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


 


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


 


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


 


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