Subsidiary, or contracts, commitments, understandings or arrangements by which the Company or any Subsidiary is or may become bound

(h)            SEC
Reports; Financial Statements. The Company has filed all reports, schedules, forms, statements and other documents required
to be filed by the Company under the Securities Act and the Exchange Act, including pursuant to Section 13(a) or 15(d) thereof,
for the three years preceding the date hereof (or such shorter period as the Company was required by law or regulation to file
such material) (the foregoing materials, including the exhibits thereto and documents incorporated by reference therein, together
with the Registration Statement, Prospectus and the Prospectus Supplement, being collectively referred to herein as the “SEC
Reports”). For the twelve months preceding the date hereof, the Company has filed the SEC Reports on a timely basis (including
any valid extension of such time of filing provided under Rule 12b-25 or under coronavirus-related relief by the SEC) and has filed
any such SEC Reports prior to the expiration of any such extension. As of their respective dates, the SEC Reports complied in all
material respects with the requirements of the Securities Act and the Exchange Act, as applicable, and none of the SEC Reports,
when filed, contained any untrue statement of a material fact or omitted 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, not misleading.
The Company is not and has never been an issuer subject to Rule 144(i) under the Securities Act. The financial statements
of the Company included in the SEC Reports comply in all material respects with applicable accounting requirements and the rules and
regulations of the Commission with respect thereto as in effect at the time of filing. Such financial statements have been prepared
in accordance with United States generally accepted accounting principles applied on a consistent basis during the periods involved
(“GAAP”), except as may be otherwise specified in such financial statements or the notes thereto and except
that unaudited financial statements may not contain all footnotes required by GAAP, and fairly present in all material respects
the financial position of the Company and its consolidated Subsidiaries as of and for the dates thereof and the results of operations
and cash flows for the periods then ended, subject, in the case of unaudited statements, to normal, immaterial, year-end audit
adjustments. The selected financial data set forth under the caption “Selected Financial Data” in the SEC Reports fairly
present, on the basis stated in such SEC Reports, the information included therein. The agreements and documents described in the
Registration Statement and the SEC Reports conform in all material aspects to the descriptions thereof contained therein and there
are no agreements or other documents required by the Securities Act and the rules and regulations thereunder to be described in
the Registration Statement, the Prospectus or the SEC Reports or to be filed with the Commission as exhibits to the Registration
Statement, that have not been so described or filed. Each agreement or other instrument (however characterized or described) to
which the Company is a party or by which it is or may be bound or affected and (i) that is referred to in the Registration Statement
or the SEC Reports, or (ii) is material to the Company’s business, has been duly authorized and validly executed by the Company,
is in full force and effect in all material respects and is enforceable against the Company and, to the Company’s knowledge,
the other parties thereto, in accordance with its terms, except (x) as such enforceability may be limited by bankruptcy, insolvency,
reorganization or similar laws affecting creditors’ rights generally, (y) as enforceability of any indemnification or contribution
provision may be limited under the federal and state securities laws, and (z) that the remedy of specific performance and injunctive
and other forms of equitable relief may be subject to the equitable defenses and to the discretion of the court before which any
proceeding therefore may be brought. None of such agreements or instruments has been assigned by the Company, and neither the Company
nor, to the best of the Company’s knowledge, any other party is in default thereunder and, to the best of the Company’s
knowledge, no event has occurred that, with the lapse of time or the giving of notice, or both, would constitute a default thereunder.
To the best of the Company’s knowledge, performance by the Company of the material provisions of such agreements or instruments
will not result in a violation of any existing applicable law, rule, regulation, judgment, order or decree of any governmental
agency or court, domestic or foreign, having jurisdiction over the Company or any of its assets or businesses, including, without
limitation, those relating to environmental laws and regulations.

former director or officer of the Company. There are no Actions required to be disclosed in the SEC Reports that have not been

filed by the Company or any Subsidiary under the Exchange Act or the Securities Act.

any Subsidiary, is, or is now expected to be, in violation of any material term of any employment contract, confidentiality, disclosure
or proprietary information agreement or non-competition agreement, or any other contract or agreement or any restrictive covenant
in favor of any third party, and the continued employment of each such executive officer does not subject the Company or any of
its Subsidiaries to any liability with respect to any of the foregoing matters. The Company and its Subsidiaries are in compliance
with all U.S. federal, state, local and foreign laws and regulations relating to employment and employment practices, terms and
conditions of employment and wages and hours, except where the failure to be in compliance could not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect.

or otherwise relating to the manufacture, processing, distribution, use, treatment, storage, disposal, transport or handling of
Hazardous Materials, as well as all authorizations, codes, decrees, demands, or demand letters, injunctions, judgments, licenses,

Laws to conduct their respective businesses; and (iii) are in compliance with all terms and conditions of any such permit,

registration and permits issued by the appropriate federal, state, local or foreign regulatory authorities applicable to the Company
(“Applicable Laws”) necessary to conduct their respective businesses as described in the SEC Reports, except
where the failure to possess such permits could not reasonably be expected to result in a Material Adverse Effect (each, an
 “Authorization”), and neither the Company nor any Subsidiary has received any notice of proceedings relating to
the revocation or modification of any Authorization or the noncompliance with any ordinance, law, rule or regulation applicable
to the Company. The disclosures in the Registration Statement concerning the effects of federal, state, local and all foreign regulation
on the Company’s business as currently contemplated are correct in all material respects. The Company is and has been in
material compliance with any term of any such Authorizations, except for any violations which would not reasonably be expected
to have a Material Adverse Effect. The Company has not received notice of any claim, action, suit, proceeding, hearing, enforcement,
investigation, arbitration or other action from any governmental authority or body or third party alleging that any product, operation
or activity is in violation of any Applicable Laws or Authorizations or has any knowledge that any such entity or third party is
considering any such claim, litigation, arbitration, action, suit, investigation or proceeding, nor, to the Company’s knowledge,

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

and the Subsidiaries are in compliance.

applications, service marks, trade names, trade secrets, inventions, copyrights, licenses and other intellectual property rights
and similar rights necessary or required for use in connection with their respective businesses as described in the SEC Reports
and which the failure to so have could have a Material Adverse Effect (collectively, the “Intellectual Property Rights”).
Neither the Company nor any Subsidiary has received a notice (written or otherwise) that any of, the Intellectual Property Rights
has expired, terminated or been abandoned, or is expected to expire or terminate or be abandoned, within two (2) years from
the date of this Agreement except where such action would not reasonably be expected to have a Material Adverse Effect. Neither
the Company nor any Subsidiary has received, since the date of the latest audited financial statements included within the SEC
Reports, a written notice of a claim or otherwise has any knowledge that the Intellectual Property Rights or any of the Company’s
products or planned products as described in the SEC Reports 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.

in such amounts as are prudent and customary in the businesses in which the Company and the Subsidiaries are engaged, including,
but not limited to, directors and officers insurance coverage at least equal to the aggregate Subscription Amount. Neither the
Company nor any Subsidiary has any reason to believe that it will not be able to renew its existing insurance coverage as and when
such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business without
a significant increase in cost.

 

(r)            Transactions

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. Except as set forth
in the SEC Reports, the Company and the Subsidiaries maintain a system of internal accounting controls sufficient to provide reasonable
assurance that: (i) transactions 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 for assets is compared with the existing assets at reasonable intervals and appropriate action is taken
with respect to any differences. The Company and the Subsidiaries have established disclosure controls and procedures (as defined
in Exchange Act Rules 13a-15(e) and 15d-15(e) for the Company and the Subsidiaries and designed such disclosure controls
and procedures to ensure that information required to be disclosed by the Company in the reports it files or submits under the
Exchange Act is recorded, processed, summarized 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 Date. Since the Evaluation Date, there have been no changes in the internal control over

investment banker, bank or other Person with respect to the transactions contemplated by the Transaction Documents. The Purchasers
shall have no obligation with respect to any fees or with respect to any claims made by or on behalf of other Persons for fees
of a type contemplated in this Section that may be due in connection with the transactions contemplated by the Transaction
Documents.

 

(u)            Investment
Company. The Company is not, and is not an Affiliate of, and immediately after receipt of payment for the Securities, will
not be or be an Affiliate of, an “investment company” within the meaning of the Investment Company Act of 1940, as
amended. The Company shall conduct its business in a manner so that it will not become an “investment company” subject
to registration under the Investment Company Act of 1940, as amended.

   

(v)            Registration
Rights. Except as described in the Registration Statement and the Prospectus, no Person has any right to cause the Company
or any Subsidiary to effect the registration under the Securities Act of any securities of the Company or any Subsidiary.

 

(w)            Listing
and Maintenance Requirements. The Common Shares are registered pursuant to Section 12(b) or 12(g) of the Exchange
Act, and the Company has taken no action designed to, or which to its knowledge is likely to have the effect of, terminating the
registration of the Common Shares under the Exchange Act nor has the Company received any notification that the Commission is contemplating
terminating such registration. Except as set forth in the Registration Statement, the Company has not, in the 12 months preceding
the date hereof, received notice from any Trading Market on which the Common Shares are or have been listed or quoted to the effect
that the Company is not in compliance with the listing or maintenance requirements of such Trading Market. Except as set forth
in the Registration Statement, 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 Shares are 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.

 

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

 

    16

     

    

 

(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 Prospectus Supplement. 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 light of the circumstances under which they were made
and when made, not misleading. The Company acknowledges and agrees that no Purchaser makes or has made any representations or warranties
with respect to the transactions contemplated hereby other than those specifically set forth in Section 3.2 hereof.

  

(z)            No
Integrated Offering. Assuming the accuracy of the Purchasers’ representations and warranties set forth in Section 3.2,
neither the Company, nor any of its Affiliates, nor any Person acting on its or their behalf has, directly or indirectly, made
any offers or sales of any security or solicited any offers to buy any security, under circumstances that would cause this offering
of the Securities to be integrated with prior offerings by the Company for purposes of (i) the Securities Act which would require
the registration of the Unregistered Warrants or the Unregistered Warrant Shares under the Securities Act, or (ii) 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.

Material Adverse Effect, the Company and its Subsidiaries each (i) has made or filed all United States federal, state and
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. The term “taxes” mean all federal, state, local,
foreign, and other net income, gross income, gross receipts, sales, use, ad valorem, transfer, franchise, profits, license, lease,
service, service use, withholding, payroll, employment, excise, severance, stamp, occupation, premium, property, windfall profits,

statements, and other documents required to be filed in respect to taxes.

Corrupt Practices. Neither the Company nor any Subsidiary, nor to the knowledge of the Company or any Subsidiary, any agent
or other person acting on behalf of the Company or any Subsidiary, has (i) directly or indirectly, used any funds for unlawful
contributions, gifts, entertainment or other unlawful expenses related to foreign or domestic political activity, (ii) made
any unlawful payment to foreign or domestic government officials or employees or to any foreign or domestic political parties or

material respect any provision of FCPA. The Company has taken reasonable steps to ensure that its accounting controls and procedures
are sufficient to cause the Company to comply in all material respects with the FCPA.

such accounting firm is a registered public accounting firm as required by the Exchange Act.

 

(ee)         Acknowledgment
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 to

Purchasers has been asked by the Company to agree, nor has any Purchaser agreed, to desist from purchasing or selling, long and/or
short, securities of the Company, or “derivative” securities based on securities issued by the Company or to hold the Shares 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 Shares, 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
shareholders’ 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

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

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.

 

(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. Such Purchaser understands that the Unregistered Warrants and the Unregistered Warrant Shares
are “restricted securities” and have not been registered under the Securities Act or any applicable state securities
law and is acquiring such Securities as principal for his, her or its own account and not with a view to or for distributing or
reselling such Securities or any part thereof in violation of the Securities Act or any applicable state securities law, has no
present intention of distributing any of such Securities in violation of the Securities Act or any applicable state securities
law and has no direct or indirect arrangement or understandings with any other persons to distribute or regarding the distribution
of such Securities in violation of the Securities Act or any applicable state securities law (this representation and warranty
not limiting such Purchaser’s right to sell such Securities pursuant to a registration statement or otherwise in compliance
with applicable federal and state securities laws).

 

    21

     

    

 

(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 Unregistered 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.

 

(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 pricing terms of the transactions contemplated hereunder and ending immediately prior to the execution hereof.
Notwithstanding the foregoing, in the case of a Purchaser that is a multi-managed investment vehicle whereby separate portfolio
managers manage separate portions of such Purchaser’s assets and the portfolio managers have no direct knowledge of the investment
decisions made by the portfolio managers managing other portions of such Purchaser’s assets, the representation set forth
above shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision
to purchase the 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.

 

    22

     

    

 

(g)      
General Solicitation. Such Purchaser is not purchasing the Unregistered Warrants as a result of any advertisement, article,
notice or other communication regarding the Securities published in any newspaper, magazine or similar media or broadcast over
television or radio or presented at any seminar or, to the knowledge of such Purchaser, any other general solicitation or general
advertisement.

 

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  
        Removal of Legends.

 

(a)               
The Unregistered Warrants and Unregistered Warrant Shares may only be disposed of in compliance with state and federal securities
laws. In connection with any transfer of Unregistered Warrants or Unregistered Warrant Shares other than pursuant to an effective
registration statement or Rule 144, to the Company or to an Affiliate of a Purchaser or in connection with a pledge as contemplated
in Section 4.1(b), the Company may require the transferor thereof to provide to the Company an opinion of counsel selected by the
transferor and reasonably acceptable to the Company, the form and substance of which opinion shall be reasonably satisfactory to
the Company, to the effect that such transfer does not require registration of such transferred Unregistered Warrants or Unregistered
Warrant Shares under the Securities Act.

 

(b)       
The Purchasers agree to the imprinting, so long as is required by this Section 4.1, of a legend on any of the Unregistered Warrants
or Unregistered Warrant Shares in the following form:

 

NEITHER THIS SECURITY NOR THE SECURITIES
INTO WHICH THIS SECURITY IS EXERCISABLE HAS BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION
OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES
ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES
ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES
ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS. THIS SECURITY AND THE SECURITIES ISSUABLE UPON EXERCISE OF THIS SECURITY
MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT WITH A REGISTERED BROKER-DEALER OR OTHER LOAN WITH A FINANCIAL INSTITUTION
THAT IS AN “ACCREDITED INVESTOR” AS DEFINED IN RULE 501(a) UNDER THE SECURITIES ACT OR OTHER LOAN SECURED BY SUCH SECURITIES.

 

    23

     

    

 

The Company acknowledges
and agrees that a Purchaser may from time to time pledge pursuant to a bona fide margin agreement with a registered broker-dealer
or grant a security interest in some or all of the Unregistered Warrants or Unregistered Warrant Shares to a financial institution
that is an “accredited investor” as defined in Rule 501(a) under the Securities Act and, if required under the terms
of such arrangement, such Purchaser may transfer pledged or secured Unregistered Warrants or Unregistered Warrant Shares to the
pledgees or secured parties. Such a pledge or transfer would not be subject to approval of the Company and no legal opinion of
legal counsel of the pledgee, secured party or pledgor shall be required in connection therewith. Further, no notice shall be required
of such pledge. At the appropriate Purchaser’s expense, the Company will execute and deliver such reasonable documentation
as a pledgee or secured party of Unregistered Warrants and Unregistered Warrant Shares may reasonably request in connection with
a pledge or transfer of the Unregistered Warrants or Unregistered Warrant Shares.

 

(c)          
Certificates evidencing the Unregistered Warrant Shares shall not contain any legend (including the legend set forth in Section
4.1(b) hereof): (i) while a registration statement covering the resale of such security is effective under the Securities Act,
or (ii) following any sale of such Unregistered Warrant Shares pursuant to Rule 144 (assuming cashless exercise of the Unregistered
Warrants), or (iii) if such Unregistered Warrant Shares are eligible for sale under Rule 144 without volume or manner-of-sale limitations
(assuming cashless exercise of the Unregistered Warrants), or (iv) if such legend is not required under applicable requirements
of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the Commission). The Company
shall cause its counsel to issue a legal opinion to the Transfer Agent or a Purchaser promptly if required by the Transfer Agent
to effect the removal of the legend hereunder, or if requested by a Purchaser, respectively. If all or any portion of an Unregistered
Warrant is exercised at a time when there is an effective registration statement to cover the resale of the Warrant Shares, or
if such Unregistered Warrant Shares may be sold under Rule 144 without volume or manner-of-sale limitations (assuming cashless
exercise of the Unregistered Warrants) or if such legend is not otherwise required under applicable requirements of the Securities
Act (including judicial interpretations and pronouncements issued by the staff of the Commission) then such Unregistered Warrant
Shares shall be issued free of all legends. The Company agrees that following such time as such legend is no longer required under
this Section 4.1(c), the Company will, no later than the earlier of (i) two (2) Trading Days and (ii) the number of Trading Days
comprising the Standard Settlement Period (as defined below) following the delivery by a Purchaser to the Company or the Transfer
Agent of a certificate representing Unregistered Warrant Shares, as applicable, issued with a restrictive legend (such date, the
 “Legend Removal Date”), deliver or cause to be delivered to such Purchaser a certificate representing such shares
that is free from all restrictive and other legends. The Company may not make any notation on its records or give instructions
to the Transfer Agent that enlarge the restrictions on transfer set forth in this Section 4. Certificates for Unregistered Warrant
Shares subject to legend removal hereunder shall be transmitted by the Transfer Agent to the Purchaser by crediting the account
of the Purchaser’s prime broker with the Depository Trust Company System as directed by such Purchaser. As used herein, “Standard
Settlement Period” means the standard settlement period, expressed in a number of Trading Days, on the Company’s
primary Trading Market with respect to the Common Shares as in effect on the date of delivery of a certificate representing Unregistered
Warrant Shares issued with a restrictive legend.

 

(d)          
In addition to such Purchaser’s other available remedies, the Company shall pay to a Purchaser, in cash, (i) as partial liquidated
damages and not as a penalty, for each $1,000 of Unregistered Warrant Shares (based on the VWAP of the Common Shares on the date
such Securities are submitted to the Transfer Agent) delivered for removal of the restrictive legend and subject to Section 4.1(c),
$10 per Trading Day (increasing to $20 per Trading Day five (5) Trading Days after such damages have begun to accrue) for each
Trading Day after the Legend Removal Date until such certificate is delivered without a legend and (ii) if the Company fails to
(a) issue and deliver (or cause to be delivered) to a Purchaser by the Legend Removal Date a certificate representing the Securities
so delivered to the Company by such Purchaser that is free from all restrictive and other legends and (b) if after the Legend Removal
Date such Purchaser purchases (in an open market transaction or otherwise) Common Shares to deliver in satisfaction of a sale by
such Purchaser of all or any portion of the number of Common Shares, or a sale of a number of Common Shares equal to all or any
portion of the number of Common Shares, that such Purchaser anticipated receiving from the Company without any restrictive legend,
then an amount equal to the excess of such Purchaser’s total purchase price (including brokerage commissions and other out-of-pocket
expenses, if any) for the Common Shares so purchased (including brokerage commissions and other out-of-pocket expenses, if any)
(the “Buy-In Price”) over the product of (A) such number of Unregistered Warrant Shares that the Company was
required to deliver to such Purchaser by the Legend Removal Date multiplied by (B) the lowest closing sale price of the Common
Shares on any Trading Day during the period commencing on the date of the delivery by such Purchaser to the Company of the applicable
Unregistered Warrant Shares (as the case may be) and ending on the date of such delivery and payment under this Section 4.1(d).

 

    24

     

    

 

(e)        
The Shares, Registered Warrants and Registered Warrant Shares shall be issued free of legends.

 

4.2  
       Furnishing of Information.

 

(a)               
Until the earliest of the time that (i) no Purchaser owns Securities or (ii) the Unregistered 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.

 

(b)     
At any time during the period commencing from the six (6) month anniversary of the date hereof and ending at such time that all
of the Unregistered Warrant Shares (assuming cashless exercise) may be sold without the requirement for the Company to be in compliance
with Rule 144(c)(1) and otherwise without restriction or limitation pursuant to Rule 144, if the Company (i) shall fail for any
reason to satisfy the current public information requirement under Rule 144(c) or (ii) has ever been an issuer described in Rule
144(i)(1)(i) or becomes an issuer in the future, and the Company shall fail to satisfy any condition set forth in Rule 144(i)(2)
(a “Public Information Failure”) then, in addition to such Purchaser’s other available remedies, the Company
shall pay to a Purchaser, in cash, as partial liquidated damages and not as a penalty, by reason of any such delay in or reduction
of its ability to sell the Unregistered Warrant Shares, an amount in cash equal to two percent (2.0%) of the aggregate Exercise
Price of such Purchaser’s Unregistered Warrants on the day of a Public Information Failure and on every thirtieth (30th)
day (pro- rated for periods totaling less than thirty days) thereafter until the earlier of (a) the date such Public Information
Failure is cured and (b) such time that such public information is no longer required  for the Purchasers to transfer the
Unregistered Warrant Shares pursuant to Rule 144.  The payments to which a Purchaser shall be entitled pursuant to this Section
4.2(b) are referred to herein as “Public Information Failure Payments.”  Public Information Failure Payments
shall be paid on the earlier of (i) the last day of the calendar month during which such Public Information Failure Payments
are incurred and (ii) the third (3rd) Business Day after the event or failure giving rise to the Public Information
Failure Payments is cured.  In the event the Company fails to make Public Information Failure Payments
in a timely manner, such Public Information Failure Payments shall bear interest at the rate of 1.5% per month (prorated
for partial months) until paid in full. Nothing herein shall limit such Purchaser’s right to pursue actual damages for the
Public Information Failure, and such Purchaser shall have the right to pursue all remedies available to it at law or in equity
including, without limitation, a decree of specific performance and/or injunctive relief.

 

    25

     

    

 

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 in a manner that would require
the registration under the Securities Act of the sale of the Unregistered Warrants or Unregistered Warrant Shares or 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 9:00 a.m. (New York City time) on the date following the date
hereof issue a press release disclosing the material terms of the transactions contemplated hereby, and (b) file a Report
on Form 6-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 or FINRA regulations, in which case the Company shall provide the
Purchasers with prior notice of such disclosure permitted under this clause (b).

  

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

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 Report on Form 6-K. The Company understands
and confirms that each Purchaser shall be relying on the foregoing covenant in effecting transactions in securities of the Company.

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) or (c) in connection with any registration statement of
the Company providing for the resale by the Purchasers of the Warrant Shares issued and issuable upon exercise of the Warrants,
the Company will indemnify each Purchaser Party, to the fullest extent permitted by applicable law, from and against any and all
losses, claims, damages, liabilities, costs (including, without limitation, reasonable attorneys’ fees) and expenses, as
incurred, arising out of or relating to (i) any untrue or alleged untrue statement of a material fact contained in such registration
statement, any prospectus or any form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus,
or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary
to make the statements therein (in the case of any prospectus or supplement thereto, in the light of the circumstances under which
they were made) not misleading, except to the extent, but only to the extent, that such untrue statements or omissions are based
solely upon information regarding such Purchaser Party furnished in writing to the Company by such Purchaser Party expressly for
use therein, or (ii) any violation or alleged violation by the Company of the Securities Act, the Exchange Act or any state securities
law, or any rule or regulation thereunder in connection therewith. 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.

 

    27

     

    

 

4.9            Reservation
of Common Shares. 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 Common Shares 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 Shares. The Company hereby agrees to use best efforts to maintain the listing or quotation of the Common Shares on
the Trading Market on which it is currently listed, and concurrently with the Closing, the Company shall have applied to list or
quote all of the Shares on such Trading Market and promptly secure the listing of all of the Shares on such Trading Market. The
Company further agrees, if the Company applies to have the Common Shares traded on any other Trading Market, it will then include
in such application all of the Shares, and will take such other action as is necessary to cause all of the Shares to be listed
or quoted on such other Trading Market as promptly as possible. The Company will then take all action reasonably necessary to continue
the listing and trading of its Common Shares 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 Shares 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 forty-five (45) Trading 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 Common Shares or Common Share Equivalents
(“Subsequent Financing”).

 

(b)            From
the date hereof until one (1) year 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 Shares or Common Share 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 Common Shares 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 Common Shares 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 Shares
or (ii) enters into, or effects a transaction under, any agreement, including, but not limited to, an equity line of credit,
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.

 

    28

     

    

 

(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 any Transaction Document) shall be offered or paid
to any Person to amend or consent to a waiver or modification of any provision of the Transaction Documents unless the same consideration
is also offered to all of the parties to such Transaction Document. For clarification purposes, this provision constitutes a separate
right granted to each Purchaser by the Company and negotiated separately by each Purchaser, and is intended for the Company to
treat the Purchasers as a class and shall not in any way be construed as the Purchasers acting in concert or as a group with respect
to the purchase, disposition or voting of Securities or otherwise.

 

4.13          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.

 

    29

     

    

 

4.14          Exercise
Procedures.  The applicable form of Notice of Exercise included in each of the Warrants set forth the totality of the
procedures required of the Purchasers in order to exercise the respective 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.

 

4.15          Form
D; Blue Sky Filings. The Company agrees to timely file a Form D with respect to the Unregistered Warrants and Unregistered
Warrant Shares as required under Regulation D and to provide a copy thereof, promptly upon request of any Purchaser. The Company
shall take such action as the Company shall reasonably determine is necessary in order to obtain an exemption for, or to qualify
the Unregistered Warrants and Unregistered Warrant Shares for, sale to the Purchasers at the Closing under applicable securities
or “Blue Sky” laws of the states of the United States, and shall provide evidence of such actions promptly upon request
of any Purchaser.

 

4.16          Registration
Statement.  As soon as practicable (and in any event within 30 calendar days of the date of this Agreement), the Company
shall file a registration statement on Form F-3 (or Form F-1 if Form F-3 is not available to the Company) providing for the resale
by the Purchasers of the Unregistered Warrant Shares issued and issuable upon exercise of the Unregistered Warrants or shall include
such Unregistered Warrant Shares issued and issuable upon exercise of the Unregistered Warrants in any other registration statement
on Form F-3 filed by the Company.  The Company shall use commercially reasonable efforts to cause such registration to become
effective within 60 days following the Closing Date and to keep such registration statement effective at all times (except for
any periods in connection with the filing of post-effective amendments as reasonably determined by Company’s counsel to be
required) until no Purchaser owns any Unregistered Warrants or Unregistered Warrant Shares issuable upon exercise thereof.

 

4.17       On
or prior to the Closing Date, the Company shall have furnished to the Placement Agent a letter substantially in the form of Exhibit
C hereto (the “Lock-Up Agreement”) from each executive officer, director and shareholder of the Company
listed on Schedule 4.17 hereto addressed to the Placement Agent. The Company will use its reasonable best efforts to enforce
the terms of each Lock-Up Agreement and will issue stop-transfer instructions to the transfer agent for the Common Shares with
respect to any transaction or contemplated transaction that would constitute a breach of or default under the applicable Lock-Up
Agreement.

 

4.18       Participation
Right. From the date hereof through the twelve (12) month anniversary of the Closing Date, neither the Company nor any of its
Subsidiaries shall, directly or indirectly, effect any Subsequent Financing unless the Company shall have first complied with this
Section 4.18. The Company acknowledges and agrees that the right set forth in this Section 4.18 is a right granted by the Company,
separately, to each Purchaser.

 

    30

     

    

 

(i)          At
least three (3) Trading Days prior to any proposed or intended Subsequent Financing, the Company shall deliver to each Purchaser
a written notice of its proposal or intention to effect a Subsequent Financing (each such notice, a “Pre-Notice”),
which Pre-Notice shall not contain any information (including, without limitation, material, non-public information) other than:
(A) a statement that the Company proposes or intends to effect a Subsequent Financing, (B) a statement that the statement in clause
(A) above does not constitute material, non-public information and (iii) a statement informing such Purchaser that it is entitled
to receive an Offer Notice (as defined below) with respect to such Subsequent Financing upon its written request. Upon the
written request of a Purchaser within one (1) Trading Day after the Company’s delivery to such Purchaser of such Pre-Notice,
and only upon a written request by such Purchaser, the Company shall promptly, but no later than one (1) Trading Day after such
request, deliver to such Purchaser an irrevocable written notice (the “Offer Notice”) of any proposed or intended
issuance or sale or exchange (the “Offer”) of the securities being offered (the “Offered Securities”)
in a Subsequent Financing, which Offer Notice shall (1) identify and describe the Offered Securities, (2) describe the price and
other terms upon which they are to be issued, sold or exchanged, and the number or amount of the Offered Securities to be issued,
sold or exchanged, (3) identify the Persons (if known) to which or with which the Offered Securities are to be offered, issued,
sold or exchanged and (4) offer to issue and sell to or exchange with all Purchasers, in the aggregate, in accordance with the
terms of the Offer, thirty percent (30%) of the Offered Securities, provided that the number of Offered Securities which each such
Purchaser shall have the right to subscribe for under this Section 4.18 shall be (a) based on such Purchaser’s pro rata portion
of the aggregate number of Shares purchased hereunder by all Purchasers (the “Basic Amount”), and (b) with respect
to each Purchaser that elects to purchase its Basic Amount, any additional portion of the Offered Securities attributable to the
Basic Amounts of other Purchasers as such Purchaser shall indicate it will purchase or acquire should the other Purchasers subscribe
for less than their Basic Amounts (the “Undersubscription Amount”). 

 

(ii)         To
accept an Offer, in whole or in part, such Purchaser must deliver a written notice to the Company prior to the end of the first
(1st) Trading Day after such Purchaser’s receipt of the Offer Notice (the “Offer Period”),
setting forth the portion of such Purchaser’s Basic Amount that such Purchaser elects to purchase and, if such Purchaser
shall elect to purchase all of its Basic Amount, the Undersubscription Amount, if any, that such Purchaser elects to purchase (in
either case, the “Notice of Acceptance”). If the Basic Amounts subscribed for by all Purchasers are less than
the total of all of the Basic Amounts, then such Purchaser who has set forth an Undersubscription Amount in its Notice of Acceptance
shall be entitled to purchase, in addition to the Basic Amounts subscribed for, the Undersubscription Amount it has subscribed
for; provided, however, if the Undersubscription Amounts subscribed for exceed the difference between the total of all the Basic
Amounts and the Basic Amounts subscribed for (the “Available Undersubscription Amount”), such Purchaser who
has subscribed for any Undersubscription Amount shall be entitled to purchase only that portion of the Available Undersubscription
Amount as the Basic Amount of such Purchaser bears to the total Basic Amounts of all Purchasers that have subscribed for Undersubscription
Amounts, subject to rounding by the Company to the extent it deems reasonably necessary. Notwithstanding the foregoing, if the
Company desires to modify or amend the terms and conditions of the Offer prior to the expiration of the Offer Period, the Company
may deliver to each Purchaser a new Offer Notice and the Offer Period shall expire on the second (2nd) Trading Day after
such Purchaser’s receipt of such new Offer Notice. 

 

    31

     

    

 

(iii)        The
Company shall have five (5) days from the expiration of the Offer Period above (A) to offer, issue, sell or exchange all or any
part of such Offered Securities as to which a Notice of Acceptance has not been given by a Purchaser (the “Refused Securities”)
pursuant to a definitive agreement(s) (the “Subsequent Financing Agreement”), but only to the offerees described
in the Offer Notice (if so described therein) and only upon terms and conditions (including, without limitation, unit prices and
interest rates) that are not more favorable to the Acquiring Person or Persons or less favorable to the Company than those set
forth in the Offer Notice and (B) to publicly announce (1) the execution of such Subsequent Financing Agreement, and (2) either
(a) the consummation of the transactions contemplated by such Subsequent Financing Agreement or (b) the termination of such Subsequent
Financing Agreement, which shall be filed with the SEC on a Current Report on Form 6-K with such Subsequent Financing Agreement
and any documents contemplated therein filed as exhibits thereto.

 

(iv)        In
the event the Company shall propose to sell less than all the Refused Securities (any such sale to be in the manner and on the
terms specified in Section 4.18(iii) above), then such Purchaser may, at its sole option and in its sole discretion, reduce the
number or amount of the Offered Securities specified in its Notice of Acceptance to an amount that shall be not less than the number
or amount of the Offered Securities that such Purchaser elected to purchase pursuant to Section 4.18(ii) above multiplied by a
fraction, (A) the numerator of which shall be the number or amount of Offered Securities the Company actually proposes to issue,
sell or exchange (including Offered Securities to be issued or sold to Purchasers pursuant to this Section 4.18 prior to such reduction)
and (B) the denominator of which shall be the original amount of the Offered Securities. In the event that any Purchaser so elects
to reduce the number or amount of Offered Securities specified in its Notice of Acceptance, the Company may not issue, sell or
exchange more than the reduced number or amount of the Offered Securities unless and until such securities have again been offered
to the Purchasers in accordance with Section 4.18(i) above.

 

(v)         Upon
the closing of the issuance, sale or exchange of all or less than all of the Refused Securities, such Purchaser shall acquire from
the Company, and the Company shall issue to such Purchaser, the number or amount of Offered Securities specified in its Notice
of Acceptance as reduced pursuant to Section 4.18(iv) above if such Purchaser has so elected, upon the terms and conditions
specified in the Offer. The purchase by such Purchaser of any Offered Securities is subject in all cases to the preparation, execution
and delivery by the Company and such Purchaser of a separate purchase agreement relating to such Offered Securities reasonably
satisfactory in form and substance to such Purchaser and its counsel.

 

(vi)        Any
Offered Securities not acquired by a Purchaser or other Persons in accordance with this Section 4.18 may not be issued, sold or
exchanged until they are again offered to such Purchaser under the procedures specified in this Agreement.

 

(vii)       The
Company and each Purchaser agree that if any Purchaser elects to participate in the Offer, neither the Subsequent Financing Agreement
with respect to such Offer nor any other transaction documents related thereto shall include any term or provision whereby such
Purchaser shall be required to agree to any restrictions on trading as to any securities of the Company or be required to consent
to any amendment to or termination of, or grant any waiver, release or the like under or in connection with, any agreement previously
entered into with the Company or any instrument received from the Company.

 

    32

     

    

 

(viii)      Notwithstanding
anything to the contrary in this Section 4.18 and unless otherwise agreed to by such Purchaser, the Company shall either confirm
in writing to such Purchaser that the transaction with respect to the Subsequent Financing has been abandoned or shall publicly
disclose its intention to issue the Offered Securities, in either case in such a manner such that such Purchaser will not be in
possession of any material, non-public information, by the fifth (5th) Business Day following delivery of the Offer
Notice. If by such fifth (5th) Business Day, no public disclosure regarding a transaction with respect to the Offered
Securities has been made, and no notice regarding the abandonment of such transaction has been received by such Purchaser, such
transaction shall be deemed to have been abandoned and such Purchaser shall not be in possession of any material, non-public information
with respect to the Company or any of its Subsidiaries. Should the Company decide to pursue such transaction with respect to the
Offered Securities, the Company shall provide such Purchaser with another Offer Notice in accordance with, and subject to, the
terms of this Section 4.18 and such Purchaser will again have the right of participation set forth in this Section 4.18. The Company
shall not be permitted to deliver more than one Offer Notice to such Purchaser in any forty-five (45) day period, except as expressly
contemplated by the last sentence of Section 4.18(ii).

 

(ix)         The
restrictions contained in this Section 4.18 shall not apply in connection with the issuance of any Exempt Issuance. The Company
shall not circumvent the provisions of this Section 4.18 by providing terms or conditions to one Purchaser that are not provided
to all.

 

ARTICLE V.

MISCELLANEOUS

 

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).

  

5.2           Fees
and Expenses. At the Closing, the Company has agreed to reimburse the Placement Agent for all expenses (including, without
limitation, fees and disbursements of the Placement Agent’s counsel and all travel and other out-of-pocket expenses) incurred
by the Placement Agent in connection with the transaction contemplated by the Transaction Documents, up to a maximum of $50,000,
taken together and not individually. Except as expressly set forth in the Transaction Documents to the contrary, each party shall
pay the fees and expenses of its advisers, counsel, accountants and other experts, if any, and all other expenses incurred by such
party incident to the negotiation, preparation, execution, delivery and performance of this Agreement. The Company shall pay all
Transfer Agent fees (including, without limitation, any fees required for same-day processing of any instruction letter delivered
by the Company), stamp taxes and other taxes and duties levied in connection with the delivery of any Securities to the Purchasers.
In addition, the Company has agreed to reimburse the lead Purchaser $15,000 for all costs and expenses incurred by it or its affiliates
in connection with the structuring, documentation, negotiation and closing of the transactions contemplated by the Transaction
Documents, by counsel to the lead Purchaser, Kelley Drye & Warren LLP.

 

5.3           Entire
Agreement. The Transaction Documents, together with the exhibits and schedules thereto, the Prospectus and the Prospectus Supplement,

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 Shares 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 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.

  

5.6            Headings.

5.7            Successors
and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their successors and permitted
assigns. The Company may not assign this Agreement or any rights or obligations hereunder without the prior written consent of
each Purchaser (other than by merger). Any Purchaser may assign any or all of its rights under this Agreement to any Person to

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

 

5.8            No
Third-Party Beneficiaries. The Placement Agent shall be a third party beneficiary of the representations and warranties of
the Company in Section 3.1 and the representations and warranties of the Purchasers in Section 3.2. This Agreement is
intended for the benefit of the parties hereto and their respective successors and permitted assigns and is not for the benefit
of, nor may any provision hereof be enforced by, any other Person, except as otherwise set forth in Section 4.8 and this Section 5.8.

 

    34

     

    

 

5.9            Governing
Law. All questions concerning the construction, validity, enforcement and interpretation of the Transaction Documents shall
be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the
principles of conflicts of law thereof. Each party agrees that all legal Proceedings concerning the interpretations, enforcement
and defense of the transactions contemplated by this Agreement and any other Transaction Documents (whether brought against a party
hereto or its respective affiliates, directors, officers, shareholders, partners, members, employees or agents) shall be commenced
exclusively in the state and federal courts sitting in the City of New York. Each party hereby irrevocably submits to the exclusive
jurisdiction of the state and federal courts sitting in the City of New York, Borough of Manhattan for the adjudication of any
dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein (including with respect
to the enforcement of any of the Transaction Documents), and hereby irrevocably waives, and agrees not to assert in any Action
or Proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such Action or Proceeding
is improper or is an inconvenient venue for such Proceeding. Each party hereby irrevocably waives personal service of process and
consents to process being served in any such Action or Proceeding by mailing a copy thereof via registered or certified mail or
overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement and
agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall
be deemed to limit in any way any right to serve process in any other manner permitted by law. If any party shall commence an Action
or Proceeding to enforce any provisions of the Transaction Documents, then, in addition to the obligations of the Company under
Section 4.7, the prevailing party in such Action or Proceeding shall be reimbursed by the non-prevailing party for its reasonable
attorneys’ fees and other costs and expenses incurred with the investigation, preparation and prosecution of such Action
or Proceeding.

  

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

 

5.11          Execution.
This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered one and the same
agreement and shall become effective when counterparts have been signed by each party and delivered to each other party, it being
understood that the parties need not sign the same counterpart. In the event that any signature is delivered by 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”

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 Common Shares 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).

 

    35

     

    

 

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

 

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

  

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

 

5.17          Independent
Nature of Purchasers’ Obligations and Rights. The obligations of each Purchaser under any Transaction Document are several
and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance
or non-performance of the obligations of any other Purchaser under any Transaction Document. Nothing contained herein or in any
other Transaction Document, and no action taken by any Purchaser pursuant hereto or thereto, shall be deemed to constitute the
Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers
are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction
Documents. Each Purchaser shall be entitled to independently protect and enforce its rights including, without limitation, the
rights arising out of this Agreement or out of the other Transaction Documents, and it shall not be necessary for any other Purchaser
to be joined as an additional party in any Proceeding for such purpose. Each Purchaser has been represented by its own separate
legal counsel in its review and negotiation of the Transaction Documents. For reasons of administrative convenience only, each
Purchaser and its respective counsel have chosen to communicate with the Company through S&W. S&W 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.

 

    36

     

    

 

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 Common Shares 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 Shares that occur after
the date of this Agreement.

 

5.21            Sales
During Pre-Settlement Period. 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 (excluding “short sales” as defined in Rule
200 of Regulation SHO) to any Person all, or any portion, of any 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, and the Company shall be
deemed unconditionally bound to sell, 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 to any Person and that any such decision to sell any Shares by such Purchaser shall be made, in
the sole discretion of such Purchaser, at the time such Purchaser elects to effect any such sale, if any.

 

5.22            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.

2.        Shelf
Registration.

 

(a)              
On or prior to each Filing Date, the Company shall prepare and file with the Commission a Registration Statement covering
the resale of all of the Registrable Securities that are not then registered on an effective Registration Statement for an offering
to be made on a continuous basis pursuant to Rule 415. Each Registration Statement filed hereunder shall be on Form F-3 (except
if the Company is not then eligible to register for resale the Registrable Securities on Form F-3, in which case such registration
shall be on another appropriate form in accordance herewith, subject to the provisions of Section 2(e)) and shall contain (unless
otherwise directed by at least 85% in interest of the Holders) substantially the “Plan of Distribution” attached
hereto as Annex A and substantially the “Selling Stockholder” section attached hereto as Annex B;
provided, however, that no Holder shall be required to be named as an “underwriter” without such Holder’s
express prior written consent. Subject to the terms of this Agreement, the Company shall use its best efforts to cause a Registration
Statement filed under this Agreement (including, without limitation, under Section 3(c)) to be declared effective under the Securities
Act as promptly as possible after the filing thereof, but in any event no later than the applicable Effectiveness Date, and shall
use its best efforts to keep such Registration Statement continuously effective under the Securities Act until the date that all
Registrable Securities covered by such Registration Statement (i) have been sold, thereunder or pursuant to Rule 144, or (ii)
may be sold without volume or manner-of-sale restrictions pursuant to Rule 144 and without the requirement for the Company to
be in compliance with the current public information requirement under Rule 144, as determined by the counsel to the Company pursuant
to a written opinion letter to such effect, addressed and acceptable to the Transfer Agent and the affected Holders (the “Effectiveness
Period”). The Company shall telephonically request effectiveness of a Registration Statement as of 5:00 p.m. (New York
City time) on a Trading Day. The Company shall immediately notify the Holders via facsimile or by e-mail of the effectiveness
of a Registration Statement on the same Trading Day that the Company telephonically confirms effectiveness with the Commission,
which shall be the date requested for effectiveness of such Registration Statement. The Company shall, by 9:30 a.m. (New York
City time) on the Trading Day after the effective date of such Registration Statement, file a final Prospectus with the Commission
as required by Rule 424. Failure to so notify the Holder within one (1) Trading Day of such notification of effectiveness or failure
to file a final Prospectus as foresaid shall be deemed an Event under Section 2(d).

 

(b)              
 Notwithstanding the registration obligations set forth in Section 2(a), if the Commission informs the Company that all
of the Registrable Securities cannot, as a result of the application of Rule 415, be registered for resale as a secondary offering
on a single registration statement, the Company agrees to promptly inform each of the Holders thereof and use its commercially
reasonable efforts to file amendments to the Initial Registration Statement as required by the Commission, covering the maximum
number of Registrable Securities permitted to be registered by the Commission, on Form F-3 or such other form available to register
for resale the Registrable Securities as a secondary offering, subject to the provisions of Section 2(e); with respect to filing
on Form F-3 or other appropriate form, and subject to the provisions of Section 2(d) with respect to the payment of liquidated
damages; provided, however, that prior to filing such amendment, the Company shall be obligated to use diligent
efforts to advocate with the Commission for the registration of all of the Registrable Securities in accordance with the SEC Guidance,
including without limitation, Compliance and Disclosure Interpretation 612.09.

 

    4

     

    

 

(c)              
Notwithstanding any other provision of this Agreement and subject to the payment of liquidated damages pursuant to Section
2(d), if the Commission or any SEC Guidance sets forth a limitation on the number of Registrable Securities permitted to be registered
on a particular Registration Statement as a secondary offering (and notwithstanding that the Company used diligent efforts to
advocate with the Commission for the registration of all or a greater portion of Registrable Securities), unless otherwise directed
in writing by a Holder as to its Registrable Securities, the number of Registrable Securities to be registered on such Registration
Statement will be reduced as follows: 

 

		a.	First, the Company shall
                                         reduce or eliminate any securities to be included other than Registrable Securities;
                                         and

 

		b.	Second, the Company shall
                                         reduce Registrable Securities represented by Warrant Shares (applied, in the case that
                                         some Warrant Shares may be registered, to the Holders on a pro rata basis based on the
                                         total number of unregistered Warrant Shares held by such Holders). 

 

In the event of a cutback hereunder,
the Company shall give the Holder at least five (5) Trading Days prior written notice along with the calculations as to such Holder’s
allotment. In the event the Company amends the Initial Registration Statement in accordance with the foregoing, the Company will
use its best efforts to file with the Commission, as promptly as allowed by Commission or SEC Guidance provided to the Company
or to registrants of securities in general, one or more registration statements on Form F-3 or such other form available to register
for resale those Registrable Securities that were not registered for resale on the Initial Registration Statement, as amended.

 

    5

     

    

 

(d)              
If: (i) the Initial Registration Statement is not filed on or prior to its Filing Date (if the Company files the Initial
Registration Statement without affording the Holders the opportunity to review and comment on the same as required by Section
3(a) herein, the Company shall be deemed to have not satisfied this clause (i)), or (ii) the Company fails to file with the Commission
a request for acceleration of a Registration Statement in accordance with Rule 461 promulgated by the Commission pursuant to the
Securities Act, within five Trading Days of the date that the Company is notified (orally or in writing, whichever is earlier)
by the Commission that such Registration Statement will not be “reviewed” or will not be subject to further review,
or (iii) prior to the effective date of a Registration Statement, the Company fails to file a pre-effective amendment and otherwise
respond in writing to comments made by the Commission in respect of such Registration Statement within ten (10) calendar days
after the receipt of comments by or notice from the Commission that such amendment is required in order for such Registration
Statement to be declared effective, or (iv) a Registration Statement registering for resale all of the Registrable Securities
is not declared effective by the Commission by the Effectiveness Date of the Initial Registration Statement, or (v) after the
effective date of a Registration Statement, such Registration Statement ceases for any reason to remain continuously effective
as to all Registrable Securities included in such Registration Statement, or the Holders are otherwise not permitted to utilize
the Prospectus therein to resell such Registrable Securities, for more than ten (10) consecutive calendar days or more than an
aggregate of fifteen (15) calendar days (which need not be consecutive calendar days) during any 12-month period (any such failure
or breach being referred to as an “Event”, and for purposes of clauses (i) and (iv), the date on which such
Event occurs, and for purpose of clause (ii) the date on which such five (5) Trading Day period is exceeded, and for purpose of
clause (iii) the date which such ten (10) calendar day period is exceeded, and for purpose of clause (v) the date on which such
ten (10) or fifteen (15) calendar day period, as applicable, is exceeded being referred to as “Event Date”),
then, in addition to any other rights the Holders may have hereunder or under applicable law, on each such Event Date and on each
monthly anniversary of each such Event Date (if the applicable Event shall not have been cured by such date) until the applicable
Event is cured, the Company shall pay to each Holder an amount in cash, as partial liquidated damages and not as a penalty, equal
to the product of 2.0% multiplied by the aggregate Subscription Amount paid by such Holder pursuant to the Purchase Agreement.
If the Company fails to pay any partial liquidated damages pursuant to this Section in full within seven days after the date payable,
the Company will pay interest thereon at a rate of 18% per annum (or such lesser maximum amount that is permitted to be paid by
applicable law) to the Holder, accruing daily from the date such partial liquidated damages are due until such amounts, plus all
such interest thereon, are paid in full. The partial liquidated damages pursuant to the terms hereof shall apply on a daily pro
rata basis for any portion of a month prior to the cure of an Event.

 

(e)              
If Form F-3 is not available for the registration of the resale of Registrable Securities hereunder, the Company shall
(i) register the resale of the Registrable Securities on another appropriate form and (ii) undertake to register the Registrable
Securities on Form F-3 as soon as such form is available, provided that the Company shall maintain the effectiveness of the Registration
Statement then in effect until such time as a Registration Statement on Form F-3 covering the Registrable Securities has been
declared effective by the Commission.

 

(f)               
Notwithstanding anything to the contrary contained herein, in no event shall the Company be permitted to name any Holder
or affiliate of a Holder as any Underwriter without the prior written consent of such Holder.

3.        Registration
Procedures.

 

In connection with
the Company’s registration obligations hereunder, the Company shall:

 

(a)              
Not less than five (5) Trading Days prior to the filing of each Registration Statement and not less than one (1) Trading
Day prior to the filing of any related Prospectus or any amendment or supplement thereto (including any document that would be
incorporated or deemed to be incorporated therein by reference), the Company shall (i) furnish to each Holder copies of all such
documents proposed to be filed, which documents (other than those incorporated or deemed to be incorporated by reference) will
be subject to the review of such Holders, and (ii) cause its officers and directors, counsel and independent registered public
accountants to respond to such inquiries as shall be necessary, in the reasonable opinion of respective counsel to each Holder,
to conduct a reasonable investigation within the meaning of the Securities Act. The Company shall not file a Registration Statement
or any such Prospectus or any amendments or supplements thereto to which the Holders of a majority of the Registrable Securities
shall reasonably object in good faith, provided that, the Company is notified of such objection in writing no later than five
(5) Trading Days after the Holders have been so furnished copies of a Registration Statement or one (1) Trading Day after the
Holders have been so furnished copies of any related Prospectus or amendments or supplements thereto. Each Holder agrees to furnish
to the Company a completed questionnaire in the form attached to this Agreement as Annex B (a “Selling Stockholder
Questionnaire”) on a date that is not less than two (2) Trading Days prior to the Filing Date or by the end of the fourth
(4th) Trading Day following the date on which such Holder receives draft materials in accordance with this Section.

 

(b)              
(i) Prepare and file with the Commission such amendments, including post-effective amendments, to a Registration Statement
and the Prospectus used in connection therewith as may be necessary to keep a Registration Statement continuously effective as
to the applicable Registrable Securities for the Effectiveness Period and prepare and file with the Commission such additional
Registration Statements in order to register for resale under the Securities Act all of the Registrable Securities, (ii) cause
the related Prospectus to be amended or supplemented by any required Prospectus supplement (subject to the terms of this Agreement),
and, as so supplemented or amended, to be filed pursuant to Rule 424, (iii) respond as promptly as reasonably possible to any
comments received from the Commission with respect to a Registration Statement or any amendment thereto and provide as promptly
as reasonably possible to the Holders true and complete copies of all correspondence from and to the Commission relating to a
Registration Statement (provided that, the Company shall excise any information contained therein which would constitute material
non-public information regarding the Company or any of its Subsidiaries), and (iv) comply in all material respects with the applicable
provisions of the Securities Act and the Exchange Act with respect to the disposition of all Registrable Securities covered by
a Registration Statement during the applicable period in accordance (subject to the terms of this Agreement) with the intended
methods of disposition by the Holders thereof set forth in such Registration Statement as so amended or in such Prospectus as
so supplemented.

 

    7

     

    

 

(c)              
If during the Effectiveness Period, the number of Registrable Securities at any time exceeds 100% of the number of shares
of Common Stock then registered in a Registration Statement, then the Company shall file as soon as reasonably practicable, but
in any case prior to the applicable Filing Date, an additional Registration Statement covering the resale by the Holders of not
less than the number of such Registrable Securities.

 

(d)              
Notify the Holders of Registrable Securities to be sold (which notice shall, pursuant to clauses (iii) through (vi) hereof,
be accompanied by an instruction to suspend the use of the Prospectus until the requisite changes have been made) as promptly
as reasonably possible (and, in the case of (i)(A) below, not less than one (1) Trading Day prior to such filing) and (if requested
by any such Person) confirm such notice in writing no later than one (1) Trading Day following the day (i)(A) when a Prospectus
or any Prospectus supplement or post-effective amendment to a Registration Statement is proposed to be filed, (B) when the Commission
notifies the Company whether there will be a “review” of such Registration Statement and whenever the Commission comments
in writing on such Registration Statement, and (C) with respect to a Registration Statement or any post-effective amendment, when
the same has become effective, (ii) of any request by the Commission or any other federal or state governmental authority for
amendments or supplements to a Registration Statement or Prospectus or for additional information, (iii) of the issuance by the
Commission or any other federal or state governmental authority of any stop order suspending the effectiveness of a Registration
Statement covering any or all of the Registrable Securities or the initiation of any Proceedings for that purpose, (iv) of the
receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification
of any of the Registrable Securities for sale in any jurisdiction, or the initiation or threatening of any Proceeding for such
purpose, (v) of the occurrence of any event or passage of time that makes the financial statements included in a Registration
Statement ineligible for inclusion therein or any statement made in a Registration Statement or Prospectus or any document incorporated
or deemed to be incorporated therein by reference untrue in any material respect or that requires any revisions to a Registration
Statement, Prospectus or other documents so that, in the case of a Registration Statement or the Prospectus, as the case may be,
it will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, and (vi) of
the occurrence or existence of any pending corporate development with respect to the Company that the Company believes may be
material and that, in the determination of the Company, makes it not in the best interest of the Company to allow continued availability
of a Registration Statement or Prospectus; provided, however, that in no event shall any such notice contain any
information which would constitute material, non-public information regarding the Company or any of its Subsidiaries.

 

    8

     

    

 

(e)              
Use its best efforts to avoid the issuance of, or, if issued, obtain the withdrawal of (i) any order stopping or suspending
the effectiveness of a Registration Statement, or (ii) any suspension of the qualification (or exemption from qualification) of
any of the Registrable Securities for sale in any jurisdiction, at the earliest practicable moment.

 

(f)               
Furnish to each Holder, without charge, at least one conformed copy of each such Registration Statement and each amendment
thereto, including financial statements and schedules, all documents incorporated or deemed to be incorporated therein by reference
to the extent requested by such Person, and all exhibits to the extent requested by such Person (including those previously furnished
or incorporated by reference) promptly after the filing of such documents with the Commission; provided, that any such item which
is available on the EDGAR system (or successor thereto) need not be furnished in physical form.

 

(g)              
Subject to the terms of this Agreement, the Company hereby consents to the use of such Prospectus and each amendment or
supplement thereto by each of the selling Holders in connection with the offering and sale of the Registrable Securities covered
by such Prospectus and any amendment or supplement thereto, except after the giving of any notice pursuant to Section 3(d).

 

(h)              
 Prior to any resale of Registrable Securities by a Holder, use its commercially reasonable efforts to register or qualify
or cooperate with the selling Holders in connection with the registration or qualification (or exemption from the Registration
or qualification) of such Registrable Securities for the resale by the Holder under the securities or Blue Sky laws of such jurisdictions
within the United States as any Holder reasonably requests in writing, to keep each registration or qualification (or exemption
therefrom) effective during the Effectiveness Period and to do any and all other acts or things reasonably necessary to enable
the disposition in such jurisdictions of the Registrable Securities covered by each Registration Statement, provided that the
Company shall not be required to qualify generally to do business in any jurisdiction where it is not then so qualified, subject
the Company to any material tax in any such jurisdiction where it is not then so subject or file a general consent to service
of process in any such jurisdiction.

 

(i)                
If requested by a Holder, cooperate with such Holder to facilitate the timely preparation and delivery of certificates
representing Registrable Securities to be delivered to a transferee pursuant to a Registration Statement, which certificates shall
be free, to the extent permitted by the Purchase Agreement, of all restrictive legends, and to enable such Registrable Securities
to be in such denominations and registered in such names as any such Holder may request.

 

    9

     

    

 

(j)                
Upon the occurrence of any event contemplated by Section 3(d), as promptly as reasonably possible under the circumstances
taking into account the Company’s good faith assessment of any adverse consequences to the Company and its stockholders
of the premature disclosure of such event, prepare a supplement or amendment, including a post-effective amendment, to a Registration
Statement or a supplement to the related Prospectus or any document incorporated or deemed to be incorporated therein by reference,
and file any other required document so that, as thereafter delivered, neither a Registration Statement nor such Prospectus will
contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were made, not misleading. If the Company notifies
the Holders in accordance with clauses (iii) through (vi) of Section 3(d) above to suspend the use of any Prospectus until the
requisite changes to such Prospectus have been made, then the Holders shall suspend use of such Prospectus. The Company will use
its best efforts to ensure that the use of the Prospectus may be resumed as promptly as is practicable. The Company shall be entitled
to exercise its right under this Section 3(j) to suspend the availability of a Registration Statement and Prospectus, subject
to the payment of partial liquidated damages otherwise required pursuant to Section 2(d), for a period not to exceed 60 calendar
days (which need not be consecutive days) in any 12-month period.

 

(k)              
Otherwise use commercially reasonable efforts to comply with all applicable rules and regulations of the Commission under
the Securities Act and the Exchange Act, including, without limitation, Rule 172 under the Securities Act, file any final Prospectus,
including any supplement or amendment thereof, with the Commission pursuant to Rule 424 under the Securities Act, promptly inform
the Holders in writing if, at any time during the Effectiveness Period, the Company does not satisfy the conditions specified
in Rule 172 and, as a result thereof, the Holders are required to deliver a Prospectus in connection with any disposition of Registrable
Securities and take such other actions as may be reasonably necessary to facilitate the registration of the Registrable Securities
hereunder.

 

(l)                
The Company shall use its best efforts to maintain eligibility for use of Form F-3 (or any successor form thereto) for
the registration of the resale of Registrable Securities.

 

(m)            
The Company may require each selling Holder to furnish to the Company a certified statement as to the number of shares
of Common Stock beneficially owned by such Holder and, if required by the Commission, the natural persons thereof that have voting
and dispositive control over the shares. During any periods that the Company is unable to meet its obligations hereunder with
respect to the registration of the Registrable Securities solely because any Holder fails to furnish such information within three
Trading Days of the Company’s request, any liquidated damages that are accruing at such time as to such Holder only shall
be tolled and any Event that may otherwise occur solely because of such delay shall be suspended as to such Holder only, until
such information is delivered to the Company.

 

    10

     

    

 

4.        Registration
Expenses. All fees and expenses incident to the performance of or compliance with, this Agreement by the Company shall be
borne by the Company whether or not any Registrable Securities are sold pursuant to a Registration Statement. The fees and expenses
referred to in the foregoing sentence shall include, without limitation, (i) all registration and filing fees (including, without
limitation, fees and expenses of the Company’s counsel and independent registered public accountants) (A) with respect to
filings made with the Commission, (B) with respect to filings required to be made with any Trading Market on which the Common
Stock is then listed for trading, and (C) in compliance with applicable state securities or Blue Sky laws reasonably agreed to
by the Company in writing (including, without limitation, fees and disbursements of counsel for the Company in connection with
Blue Sky qualifications or exemptions of the Registrable Securities), (ii) printing expenses (including, without limitation, expenses
of printing certificates for Registrable Securities), (iii) messenger, telephone and delivery expenses, (iv) fees and disbursements
of counsel for the Company, (v) Securities Act liability insurance, if the Company so desires such insurance, and (vi) fees and
expenses of all other Persons retained by the Company in connection with the consummation of the transactions contemplated by
this Agreement. In addition, the Company shall be responsible for all of its internal expenses incurred in connection with the
consummation of the transactions contemplated by this Agreement (including, without limitation, all salaries and expenses of its
officers and employees performing legal or accounting duties), the expense of any annual audit and the fees and expenses incurred
in connection with the listing of the Registrable Securities on any securities exchange as required hereunder. In no event shall
the Company be responsible for any broker or similar commissions of any Holder or, except to the extent provided for in the Transaction
Documents, any legal fees or other costs of the Holders.

 

    11

     

    

 

5.        Indemnification.

 

(a)              
Indemnification by the Company. The Company shall, notwithstanding any termination of this Agreement, indemnify
and hold harmless each Holder, the officers, directors, members, partners, agents, brokers (including brokers who offer and sell
Registrable Securities as principal as a result of a pledge or any failure to perform under a margin call of Common Stock), investment
advisors and 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 each of them, each Person who controls any such Holder (within the meaning of Section
15 of the Securities Act or Section 20 of the Exchange Act) and the officers, directors, members, stockholders, partners, agents
and 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 each such controlling Person, to the fullest extent permitted by applicable law, from and
against any and all losses, claims, damages, liabilities, costs (including, without limitation, reasonable attorneys’ fees)
and expenses (collectively, “Losses”), as incurred, arising out of or relating to (1) any untrue or alleged
untrue statement of a material fact contained in a Registration Statement, any Prospectus or any form of prospectus or in any
amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission
of a material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus or
supplement thereto, in light of the circumstances under which they were made) not misleading or (2) any violation or alleged violation
by the Company of the Securities Act, the Exchange Act or any state securities law, or any rule or regulation thereunder, in connection
with the performance of its obligations under this Agreement, except to the extent, but only to the extent, that (i) such untrue
statements or omissions are based solely upon information regarding such Holder furnished in writing to the Company by such Holder
expressly for use therein, or to the extent that such information relates to such Holder or such Holder’s proposed method
of distribution of Registrable Securities and was reviewed and expressly approved in writing by such Holder expressly for use
in a Registration Statement, such Prospectus or in any amendment or supplement thereto (it being understood that the Holder has
approved Annex A hereto for this purpose) or (ii) in the case of an occurrence of an event of the type specified in Section 3(d)(iii)-(vi),
the use by such Holder of an outdated, defective or otherwise unavailable Prospectus after the Company has notified such Holder
in writing that the Prospectus is outdated, defective or otherwise unavailable for use by such Holder and prior to the receipt
by such Holder of the Advice contemplated in Section 6(d). The Company shall notify the Holders promptly of the institution, threat
or assertion of any Proceeding arising from or in connection with the transactions contemplated by this Agreement of which the
Company is aware. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of
such indemnified person and shall survive the transfer of any Registrable Securities by any of the Holders in accordance with
Section 6(h).

 

    12

     

    

 

(b)              
Indemnification by Holders. Each Holder shall, severally and not jointly, indemnify and hold harmless the Company,
its directors, officers, agents and employees, each Person who controls the Company (within the meaning of Section 15 of the Securities
Act and Section 20 of the Exchange Act), and the directors, officers, agents or employees of such controlling Persons, to the
fullest extent permitted by applicable law, from and against all Losses, as incurred, to the extent arising out of or based solely
upon: any untrue or alleged untrue statement of a material fact contained in any Registration Statement, any Prospectus, or in
any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged
omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus
or supplement thereto, in light of the circumstances under which they were made) not misleading (i) to the extent, but only to
the extent, that such untrue statement or omission is contained in any information so furnished in writing by such Holder to the
Company expressly for inclusion in such Registration Statement or such Prospectus or (ii) to the extent, but only to the extent,
that such information relates to such Holder’s information provided in the Selling Stockholder Questionnaire or the proposed
method of distribution of Registrable Securities and was reviewed and expressly approved in writing by such Holder expressly for
use in a Registration Statement (it being understood that the Holder has approved Annex A hereto for this purpose), such Prospectus
or in any amendment or supplement thereto. In no event shall the liability of a selling Holder be greater in amount than the dollar
amount of the proceeds (net of all expenses paid by such Holder in connection with any claim relating to this Section 5 and the
amount of any damages such Holder has otherwise been required to pay by reason of such untrue statement or omission) received
by such Holder upon the sale of the Registrable Securities included in the Registration Statement giving rise to such indemnification
obligation.

 

    13

     

    

 

(c)              
Conduct of Indemnification Proceedings. If any Proceeding shall be brought or asserted against any Person entitled
to indemnity hereunder (an “Indemnified Party”), such Indemnified Party shall promptly notify the Person from
whom indemnity is sought (the “Indemnifying Party”) in writing, and the Indemnifying Party shall have the right
to assume the defense thereof, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment
of all fees and expenses incurred in connection with defense thereof, provided that the failure of any Indemnified Party to give
such notice shall not relieve the Indemnifying Party of its obligations or liabilities pursuant to this Agreement, except (and
only) to the extent that it shall be finally determined by a court of competent jurisdiction (which determination is not subject
to appeal or further review) that such failure shall have materially and adversely prejudiced the Indemnifying Party.

 

An Indemnified
Party shall have the right to employ separate counsel in any such Proceeding and to participate in the defense thereof, but the
fees and expenses of such counsel shall be at the expense of such Indemnified Party or Parties unless: (1) the Indemnifying Party
has agreed in writing to pay such fees and expenses, (2) the Indemnifying Party shall have failed promptly to assume the defense
of such Proceeding and to employ counsel reasonably satisfactory to such Indemnified Party in any such Proceeding, or (3) the
named parties to any such Proceeding (including any impleaded parties) include both such Indemnified Party and the Indemnifying
Party, and counsel to the Indemnified Party shall reasonably believe that a material conflict of interest is likely to exist if
the same counsel were to represent such Indemnified Party and the Indemnifying Party (in which case, if such Indemnified Party
notifies the Indemnifying Party in writing that it elects to employ separate counsel at the expense of the Indemnifying Party,
the Indemnifying Party shall not have the right to assume the defense thereof and the reasonable fees and expenses of no more
than one separate counsel shall be at the expense of the Indemnifying Party). The Indemnifying Party shall not be liable for any
settlement of any such Proceeding effected without its written consent, which consent shall not be unreasonably withheld or delayed.
No Indemnifying Party shall, without the prior written consent of the Indemnified Party, effect any settlement of any pending
Proceeding in respect of which any Indemnified Party is a party, unless such settlement includes an unconditional release of such
Indemnified Party from all liability on claims that are the subject matter of such Proceeding.

 

    14

     

    

 

Subject
to the terms of this Agreement, all reasonable fees and expenses of the Indemnified Party (including reasonable fees and expenses
to the extent incurred in connection with investigating or preparing to defend such Proceeding in a manner not inconsistent with
this Section) shall be paid to the Indemnified Party, as incurred, within ten Trading Days of written notice thereof to the Indemnifying
Party, provided that the Indemnified Party shall promptly reimburse the Indemnifying Party for that portion of such fees and expenses
applicable to such actions for which such Indemnified Party is finally determined by a court of competent jurisdiction (which
determination is not subject to appeal or further review) not to be entitled to indemnification hereunder.

 

(d)              
Contribution. If the indemnification under Section 5(a) or 5(b) is unavailable to an Indemnified Party or insufficient
to hold an Indemnified Party harmless for any Losses, then each Indemnifying Party shall contribute to the amount paid or payable
by such Indemnified Party, in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and Indemnified
Party in connection with the actions, statements or omissions that resulted in such Losses as well as any other relevant equitable
considerations. The relative fault of such Indemnifying Party and Indemnified Party shall be determined by reference to, among
other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission
or alleged omission of a material fact, has been taken or made by, or relates to information supplied by, such Indemnifying Party
or Indemnified Party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent
such action, statement or omission. The amount paid or payable by a party as a result of any Losses shall be deemed to include,
subject to the limitations set forth in this Agreement, any reasonable attorneys’ or other fees or expenses incurred by
such party in connection with any Proceeding to the extent such party would have been indemnified for such fees or expenses if
the indemnification provided for in this Section was available to such party in accordance with its terms.

 

The parties
hereto agree that it would not be just and equitable if contribution pursuant to this Section 5(d) were determined by pro rata
allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the
immediately preceding paragraph. In no event shall the contribution obligation of a Holder of Registrable Securities be greater
in amount than the dollar amount of the proceeds (net of all expenses paid by such Holder in connection with any claim relating
to this Section 5 and the amount of any damages such Holder has otherwise been required to pay by reason of such untrue or alleged
untrue statement or omission or alleged omission) received by it upon the sale of the Registrable Securities giving rise to such
contribution obligation.

 

The indemnity
and contribution agreements contained in this Section are in addition to any liability that the Indemnifying Parties may have
to the Indemnified Parties.

 

    15

     

    

 

6.        Miscellaneous.

 

(a)              
Remedies. In the event of a breach by the Company or by a Holder of any of their respective obligations under this
Agreement, each Holder or the Company, as the case may be, in addition to being entitled to exercise all rights granted by law
and under this Agreement, including recovery of damages, shall be entitled to specific performance of its rights under this Agreement.
Each of the Company and each Holder agrees that monetary damages would not provide adequate compensation for any losses incurred
by reason of a breach by it of any of the provisions of this Agreement and hereby further agrees that, in the event of any action
for specific performance in respect of such breach, it shall not assert or shall waive the defense that a remedy at law would
be adequate.

 

(b)              
No Piggyback on Registrations; Prohibition on Filing Other Registration Statements. Neither the Company nor any
of its security holders (other than the Holders in such capacity pursuant hereto) may include securities of the Company in any
Registration Statements other than the Registrable Securities. The Company shall not file any other registration statements until
all Registrable Securities are registered pursuant to a Registration Statement that is declared effective by the Commission, provided
that this Section 6(b) shall not prohibit the Company from filing amendments to registration statements filed prior to the date
of this Agreement.

 

(c)              
[RESERVED]

 

(d)              
Discontinued Disposition. By its acquisition of Registrable Securities, each Holder agrees that, upon receipt of
a notice from the Company of the occurrence of any event of the kind described in Section 3(d)(iii) through (vi), such Holder
will forthwith discontinue disposition of such Registrable Securities under a Registration Statement until it is advised in writing
(the “Advice”) by the Company that the use of the applicable Prospectus (as it may have been supplemented or
amended) may be resumed. The Company will use its best efforts to ensure that the use of the Prospectus may be resumed as promptly
as is practicable. The Company agrees and acknowledges that any periods during which the Holder is required to discontinue the
disposition of the Registrable Securities hereunder shall be subject to the provisions of Section 2(d).

 

    16

     

    

 

(e)              
Piggy-Back Registrations. If, at any time during the Effectiveness Period, there is not an effective Registration
Statement covering all of the Registrable Securities, and in particular the Warrant Shares, and the Company shall determine to
prepare and file with the Commission a registration statement relating to an offering for its own account or the account of others
under the Securities Act of any of its equity securities, other than on Form S-4 or Form S-8 (each as promulgated under the Securities
Act) or their then equivalents relating to equity securities to be issued solely in connection with any acquisition of any entity
or business or equity securities issuable in connection with the Company’s stock option or other employee benefit plans,
then the Company shall deliver to each Holder a written notice of such determination and, if within fifteen days after the date
of the delivery of such notice, any such Holder shall so request in writing, the Company shall include in such registration statement
all or any part of such Registrable Securities such Holder requests to be registered; provided, however, that the
Company shall not be required to register any Registrable Securities pursuant to this Section 6(e) that are eligible for resale
pursuant to Rule 144 (without volume restrictions or current public information requirements) promulgated by the Commission pursuant
to the Securities Act or that are the subject of a then effective Registration Statement that is available for resales or other
dispositions by such Holder.

 

(f)               
Amendments and Waivers. The provisions of this Agreement, including the provisions of this sentence, may not be
amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, unless the
same shall be in writing and signed by the Company and the Holders of 50.1% or more of the then outstanding Registrable Securities
(for purposes of clarification, this includes any Registrable Securities issuable upon exercise or conversion of any Security),
provided that, if any amendment, modification or waiver disproportionately and adversely impacts a Holder (or group of Holders),
the consent of such disproportionately impacted Holder (or group of Holders) shall be required. If a Registration Statement does
not register all of the Registrable Securities pursuant to a waiver or amendment done in compliance with the previous sentence,
then the number of Registrable Securities to be registered for each Holder shall be reduced pro rata among all Holders and each
Holder shall have the right to designate which of its Registrable Securities shall be omitted from such Registration Statement.
Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with respect to a matter that relates
exclusively to the rights of a Holder or some Holders and that does not directly or indirectly affect the rights of other Holders
may be given only by such Holder or Holders of all of the Registrable Securities to which such waiver or consent relates; provided,
however, that the provisions of this sentence may not be amended, modified, or supplemented except in accordance with the
provisions of the first sentence of this Section 6(f). No consideration 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 also is offered to all of the parties
to this Agreement.

 

(g)              
Notices. Any and all notices or other communications or deliveries required or permitted to be provided hereunder
shall be delivered as set forth in the Purchase Agreement.

 

    17

     

    

 

(h)              
Successors and Assigns. This Agreement shall inure to the benefit of and be binding upon the successors and permitted
assigns of each of the parties and shall inure to the benefit of each Holder. The Company may not assign (except by merger) its
rights or obligations hereunder without the prior written consent of all of the Holders of the then outstanding Registrable Securities.
Each Holder may assign their respective rights hereunder in the manner and to the Persons as permitted under Section 5.8 of the
Purchase Agreement.

 

(i)                
No Inconsistent Agreements. Neither the Company nor any of its Subsidiaries has entered, as of the date hereof,
nor shall the Company or any of its Subsidiaries, on or after the date of this Agreement, enter into any agreement with respect
to its securities, that would have the effect of impairing the rights granted to the Holders in this Agreement or otherwise conflicts
with the provisions hereof. Except as set forth on Schedule 6(i), neither the Company nor any of its Subsidiaries has previously
entered into any agreement granting any registration rights with respect to any of its securities to any Person that have not
been satisfied in full.

 

(j)                
Execution and Counterparts. 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 the other party, it being understood that both 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.

 

(k)              
Governing Law. All questions concerning the construction, validity, enforcement and interpretation of this Agreement
shall be determined in accordance with the provisions of the Purchase Agreement.

 

(l)                
Cumulative Remedies. The remedies provided herein are cumulative and not exclusive of any other remedies provided
by law.

 

(m)            
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.

 

    18

     

    

 

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

 

(o)              
Independent Nature of Holders’ Obligations and Rights. The obligations of each Holder hereunder are several
and not joint with the obligations of any other Holder hereunder, and no Holder shall be responsible in any way for the performance
of the obligations of any other Holder hereunder. Nothing contained herein or in any other agreement or document delivered at
any closing, and no action taken by any Holder pursuant hereto or thereto, shall be deemed to constitute the Holders as a partnership,
an association, a joint venture or any other kind of group or entity, or create a presumption that the Holders are in any way
acting in concert or as a group or entity with respect to such obligations or the transactions contemplated by this Agreement
or any other matters, and the Company acknowledges that the Holders are not acting in concert or as a group, and the Company shall
not assert any such claim, with respect to such obligations or transactions. Each Holder shall be entitled to protect and enforce
its rights, including without limitation the rights arising out of this Agreement, and it shall not be necessary for any other
Holder to be joined as an additional party in any proceeding for such purpose. The use of a single agreement with respect to the
obligations of the Company contained was solely in the control of the Company, not the action or decision of any Holder, and was
done solely for the convenience of the Company and not because it was required or requested to do so by any Holder. It is expressly
understood and agreed that each provision contained in this Agreement is between the Company and a Holder, solely, and not between
the Company and the Holders collectively and not between and among Holders.

Annex A

 

Plan of Distribution

 

Each Selling Stockholder
(the “Selling Stockholders”) of the securities and any of their pledgees, assignees and successors-in-interest
may, from time to time, sell any or all of their securities covered hereby on the principal Trading Market or any other stock
exchange, market or trading facility on which the securities are traded or in private transactions. These sales may be at fixed
or negotiated prices. A Selling Stockholder may use any one or more of the following methods when selling securities:

 

		·	ordinary brokerage
                                         transactions and transactions in which the broker-dealer solicits purchasers;

 

		·	block trades
                                         in which the broker-dealer will attempt to sell the securities as agent but may position
                                         and resell a portion of the block as principal to facilitate the transaction;

 

		·	purchases by
                                         a broker-dealer as principal and resale by the broker-dealer for its account;

 

		·	an exchange
                                         distribution in accordance with the rules of the applicable exchange;

 

		·	privately negotiated
                                         transactions;

 

		·	settlement
                                         of short sales;

 

		·	in transactions
                                         through broker-dealers that agree with the Selling Stockholders to sell a specified number
                                         of such securities at a stipulated price per security;

 

		·	through the
                                         writing or settlement of options or other hedging transactions, whether through an options
                                         exchange or otherwise;

 

		·	a combination
                                         of any such methods of sale; or

 

		·	any other method
                                         permitted pursuant to applicable law.

 

The Selling Stockholders
may also sell securities under Rule 144 or any other exemption from registration under the Securities Act of 1933, as amended
(the “Securities Act”), if available, rather than under this prospectus.

 

Broker-dealers engaged
by the Selling Stockholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions
or discounts from the Selling Stockholders (or, if any broker-dealer acts as agent for the purchaser of securities, from the purchaser)
in amounts to be negotiated, but, except as set forth in a supplement to this Prospectus, in the case of an agency transaction
not in excess of a customary brokerage commission in compliance with FINRA Rule 2440; and in the case of a principal transaction
a markup or markdown in compliance with FINRA IM-2440.

 

     

     

    

 

In connection with
the sale of the securities or interests therein, the Selling Stockholders may enter into hedging transactions with broker-dealers
or other financial institutions, which may in turn engage in short sales of the securities in the course of hedging the positions
they assume. The Selling Stockholders may also sell securities short and deliver these securities to close out their short positions,
or loan or pledge the securities to broker-dealers that in turn may sell these securities. The Selling Stockholders may also enter
into option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities
which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which
securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended
to reflect such transaction).

 

The Selling Stockholders
and any broker-dealers or agents that are involved in selling the securities may be deemed to be “underwriters” within
the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers
or agents and any profit on the resale of the securities purchased by them may be deemed to be underwriting commissions or discounts
under the Securities Act. Each Selling Stockholder has informed the Company that it does not have any written or oral agreement
or understanding, directly or indirectly, with any person to distribute the securities.

 

The Company is required
to pay certain fees and expenses incurred by the Company incident to the registration of the securities. The Company has agreed
to indemnify the Selling Stockholders against certain losses, claims, damages and liabilities, including liabilities under the
Securities Act.

 

We agreed to keep
this prospectus effective until the earlier of (i) the date on which the securities may be resold by the Selling Stockholders
without registration and without regard to any volume or manner-of-sale limitations by reason of Rule 144, without the requirement
for the Company to be in compliance with the current public information under Rule 144 under the Securities Act or any other rule
of similar effect or (ii) all of the securities have been sold pursuant to this prospectus or Rule 144 under the Securities Act
or any other rule of similar effect. The resale securities will be sold only through registered or licensed brokers or dealers
if required under applicable state securities laws. In addition, in certain states, the resale securities covered hereby may not
be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or
qualification requirement is available and is complied with.

 

Under applicable rules
and regulations under the Exchange Act, any person engaged in the distribution of the resale securities may not simultaneously
engage in market making activities with respect to the common stock for the applicable restricted period, as defined in Regulation
M, prior to the commencement of the distribution. In addition, the Selling Stockholders will be subject to applicable provisions
of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases
and sales of the common stock by the Selling Stockholders or any other person. We will make copies of this prospectus available
to the Selling Stockholders and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior
to the time of the sale (including by compliance with Rule 172 under the Securities Act).

SELLING SHAREHOLDERS

 

The common stock being
offered by the selling shareholders are those previously issued to the selling shareholders, and those issuable to the selling
shareholders, upon exercise of the warrants. For additional information regarding the issuances of those shares of common stock
and warrants, see "Private Placement of Common Shares and Warrants" above. We are registering the shares of common stock
in order to permit the selling shareholders to offer the shares for resale from time to time. Except for the ownership of the
shares of common stock and the warrants, the selling shareholders have not had any material relationship with us within the past
three years.

 

The table below lists
the selling shareholders and other information regarding the beneficial ownership of the shares of common stock by each of the
selling shareholders. The second column lists the number of shares of common stock beneficially owned by each selling shareholder,
based on its ownership of the shares of common stock and warrants, as of ________, 2020, assuming exercise of the warrants held
by the selling shareholders on that date, without regard to any limitations on exercises.

 

The third column lists
the shares of common stock being offered by this prospectus by the selling shareholders.

 

In accordance with
the terms of a registration rights agreement with the selling shareholders, this prospectus generally covers the resale of the
sum of (i) the number of shares of common stock issued to the selling shareholders in the __________________ and (ii) the maximum
number of shares of common stock issuable upon exercise of the related warrants, determined as if the outstanding warrants were
exercised in full as of the trading day immediately preceding the date this registration statement was initially filed with the
SEC, each as of the trading day immediately preceding the applicable date of determination and all subject to adjustment as provided
in the registration right agreement, without regard to any limitations on the exercise of the warrants. The fourth column assumes
the sale of all of the shares offered by the selling shareholders pursuant to this prospectus.

 

Under the terms of
the warrants, a selling shareholder may not exercise the warrants to the extent such exercise would cause such selling shareholder,
together with its affiliates and attribution parties, to beneficially own a number of shares of common stock which would exceed
[4.99%][9.99%]1 of our then outstanding
common stock following such exercise, excluding for purposes of such determination shares of common stock issuable upon exercise
of the warrants which have not been exercised. The number of shares in the second column does not reflect this limitation. The
selling shareholders may sell all, some or none of their shares in this offering. See "Plan of Distribution."
