and is in good standing (or such equivalent concept to the extent such equivalent concept exists under the law of such jurisdiction)
as a foreign corporation or other entity in each jurisdiction in which the nature of the business conducted or property owned

and no Proceeding has been instituted in any such jurisdiction revoking, limiting or curtailing or seeking to revoke, limit or
curtail such power and authority or qualification.

of proceedings relating to the revocation or modification of any Material Permit.

and procedures to ensure that information required to be disclosed by the Company in the reports it files or submits under the

the Company and the Subsidiaries as of the end of the period covered by the most recently filed periodic report under the Exchange

the date hereof, received notice from any Trading Market on which the Ordinary Shares are or have been listed or quoted to the

such other established clearing corporation) in connection with such electronic transfer.

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 articles of association (or similar
charter documents) or the laws of its jurisdiction of incorporation that is or would become applicable to the Purchasers as a result
of the Purchasers and the Company fulfilling their obligations or exercising their rights under the Transaction Documents, including
without limitation as a result of the Company’s issuance of the Securities and the Purchasers’ ownership of the Securities.


 


(y)              
Disclosure. Except with respect to the material terms and conditions of the transactions contemplated by the Transaction
Documents, the Company confirms that neither it nor any other Person acting on its behalf has provided any of the Purchasers or
their agents or counsel with any information that it believes constitutes or might constitute material, non-public information
which is not otherwise disclosed in the 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 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 (it being understood that such disclosure furnished by or on behalf of the Company to the Purchasers includes the SEC
Reports). The Company acknowledges and agrees that no Purchaser makes or has made any representations or warranties with respect

Section 3.2, neither the Company nor any of its Subsidiaries nor, to the Company’s knowledge, any of its controlled Affiliates,
nor any Person acting on its or their behalf (other than the Placement Agent), has, directly or indirectly, made any offers or
sales of any security or solicited any offers to buy any security, under circumstances that would cause this offering of the Securities
to be integrated with prior offerings by the Company for purposes of any applicable shareholder approval provisions of any Trading
Market on which any of the securities of the Company are listed or designated.

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 Shares and Warrants 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 current intention of filing for reorganization or liquidation under the bankruptcy
or reorganization laws of any jurisdiction within one year from the Closing Date. The SEC Reports set 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.

Tax Status. Except for matters that would not, individually or in the aggregate, have or reasonably be expected
to result in a 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, except for such taxes, if any, as are being contested in good
faith and as to which adequate reserves have been established by the Company 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.

respect any provision of FCPA.

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

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 Ordinary 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, 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.

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 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.


 


(c)              
Purchaser Status. At the time such Purchaser was offered the Securities, it was, and as of the date hereof it is,
and on each date on which it exercises any Warrants it will be, either: (i) an “accredited investor” as defined in
Rule 501(a)(1), (a)(2), (a)(3), (a)(7) or (a)(8) under the Securities Act or (ii) a “qualified institutional buyer”
as defined in Rule 144A(a) under the Securities Act.


 


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


 






    22


     


    

 


(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 notice of the transaction contemplated hereunder (written or oral) from the Company or any other
Person representing the Company 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.


 


(g)              
Purchaser Independence. Such Purchaser acknowledges that such Purchaser is acting independently of any other Purchaser
(other than with respect to an Affiliate of such Purchaser that is also a Purchaser hereunder) in connection with the purchase
of the Securities hereunder and is not acting in concert with any other Purchaser (other than with respect to an Affiliate of
such Purchaser that is also a Purchaser hereunder) for the purposes of the Irish Takeover
Panel Act 1997, Takeover Rules, 2013, and that no individual Purchaser or group of Purchasers acting in concert will own 30% or
more of the Company's issued share capital on the Closing Date.


 






    23


     


    

 


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


 


ARTICLE IV.

OTHER AGREEMENTS OF THE PARTIES


 


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


 


4.2             
Furnishing of Information. Until the earlier of the time that (i) no Purchaser owns Securities or (ii) the Warrants
have expired, the Company covenants to timely file (or obtain extensions in respect thereof and file within the applicable grace
period) all reports required to be filed by the Company after the date hereof pursuant to the Exchange Act, provided that the Company
is then subject to the reporting requirements of the Exchange Act.


 


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


 






    24


     


    

 


4.4             
Securities Laws Disclosure; Publicity. The Company shall (a) by the Disclosure Time, issue a press release disclosing
the material terms of the transactions contemplated hereby, and (b) file a Current Report on Form 8-K, including the Transaction
Documents as exhibits thereto, with the Commission within the time required by the Exchange Act. From and after the issuance of
such press release, the Company represents to the Purchasers that it shall have publicly disclosed all material, non-public information
delivered to any of the Purchasers by the Company or any of its Subsidiaries, or any of their respective officers, directors,
employees or agents in connection with the transactions contemplated by the Transaction Documents. In addition, effective upon
the issuance of such press release, the Company acknowledges and agrees that any and all confidentiality or similar obligations
under any agreement, whether written or oral, between the Company, any of its Subsidiaries or any of their respective officers,
directors, agents, employees or Affiliates on the one hand, and any of the Purchasers or any of their Affiliates on the other
hand, shall terminate. Notwithstanding the foregoing, the Company shall not publicly disclose the name of any Purchaser, or include
the name of any Purchaser in any filing with the Commission or any regulatory agency or Trading Market, without the prior written
consent of such Purchaser, except (a) as required by federal securities law in connection with the filing of final Transaction
Documents with the Commission and (b) to the extent such disclosure is required by law or Trading Market regulations, in which
case the Company shall, to the extent permitted by law, 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 Information. Except with respect to the material terms and conditions of the transactions contemplated
by the Transaction Documents, which shall be disclosed pursuant to Section 4.4, the Company covenants and agrees that neither it
nor any other Person acting on its behalf will provide any Purchaser or its agents or counsel with any information that constitutes,
or the Company reasonably believes constitutes, material non-public information, unless prior thereto such Purchaser shall have
consented to the receipt of such information and agreed with the Company to keep such information confidential. The Company understands
and confirms that each Purchaser shall be relying on the foregoing covenant in effecting transactions in securities of the Company.
To the extent that the Company delivers any material, non-public information to a Purchaser without such Purchaser’s consent,
the Company hereby covenants and agrees that such Purchaser shall not have any duty of confidentiality to the Company, any of its
Subsidiaries, or any of their respective officers, directors, agents, employees or Affiliates, or a duty to the Company, any of
its Subsidiaries or any of their respective officers, directors, agents, employees or Affiliates not to trade on the basis of,
such material, non-public information, provided that the Purchaser shall remain subject to applicable law. To the extent that any
notice provided pursuant to any Transaction Document constitutes, or contains, material, non-public information regarding the Company
or any Subsidiaries, the Company shall simultaneously file such notice with the Commission pursuant to a Current Report on Form
8-K. The Company understands and confirms that each Purchaser shall be relying on the foregoing covenant in effecting transactions
in securities of the Company.


 






    25


     


    

 


4.7             
Use of Proceeds. Except as set forth in the Prospectus Supplement, the Company shall use the net proceeds from the
issuance and sale of the Securities hereunder for general corporate purposes and shall not use such proceeds: (a) for the acquisition
of any Ordinary Shares or Ordinary Share Equivalents, (b) for the settlement of any outstanding litigation or (c) in violation
of FCPA or OFAC regulations.


 


4.8             
Indemnification of Purchasers. Subject to the provisions of this Section 4.8, the Company will indemnify and hold
each Purchaser and its directors, officers, shareholders, members, partners, employees and agents (and any other Persons with
a functionally equivalent role of a Person holding such titles notwithstanding a lack of such title or any other title), each
Person who controls such Purchaser (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act),
and the directors, officers, shareholders, agents, members, partners or employees (and any other Persons with a functionally equivalent
role of a Person holding such titles notwithstanding a lack of such title or any other title) of such controlling persons (each,
a “Purchaser Party”) harmless from any and all losses, liabilities, obligations, claims, contingencies, damages,
costs and expenses, including all judgments, amounts paid in settlements, court costs and reasonable attorneys’ fees and
costs of investigation that any such Purchaser Party may suffer or incur as a result of or relating to (a) any breach of any of
the representations, warranties, covenants or agreements made by the Company in this Agreement or in the other Transaction Documents
or (b) any action instituted against the Purchaser Parties in any capacity, or any of them or their respective Affiliates, by
any shareholder 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 shareholder or any violations by such Purchaser Party of state or federal securities laws or any conduct by such Purchaser
Party which is finally judicially determined to constitute fraud, gross negligence or willful misconduct). If any action shall
be brought against any Purchaser Party in respect of which indemnity may be sought pursuant to this Agreement, such Purchaser
Party shall promptly notify the Company in writing, and the Company shall have the right to assume the defense thereof with counsel
of its own choosing reasonably acceptable to the Purchaser Party. Any Purchaser Party shall have the right to employ separate
counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense
of such Purchaser Party except to the extent that (x) the employment thereof has been specifically authorized by the Company in
writing, (y) the Company has failed after a reasonable period of time to assume such defense and to employ counsel or (z) in such
action there is, in the reasonable opinion of counsel, a material conflict on any material issue between the position of the Company
and the position of such Purchaser Party, in which case the Company shall be responsible for the reasonable fees and expenses
of no more than one such separate counsel. The Company will not be liable to any Purchaser Party under this Agreement (1) for
any settlement by a Purchaser Party effected without the Company’s prior written consent, which shall not be unreasonably
withheld or delayed; or (2) to the extent, but only to the extent that a loss, claim, damage or liability is attributable to any
Purchaser Party’s breach of any of the representations, warranties, covenants or agreements made by such Purchaser Party
in this Agreement or in the other Transaction Documents. The indemnification required by this Section 4.8 shall be made by periodic
payments of the amount thereof during the course of the investigation or defense, as and when bills are received or are incurred.
The indemnity agreements contained herein shall be in addition to any cause of action or similar right of any Purchaser Party
against the Company or others and any liabilities the Company may be subject to pursuant to law.


 






    26


     


    

 


4.9             
Reservation of Ordinary Shares; Aggregate Nominal Amount of Warrant 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 Ordinary 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. The Company acknowledges that each Purchaser that so elects under Section 2.2(b)(ii) herein has
paid the aggregate nominal amount of the Ordinary Shares issuable upon exercise of such Purchaser’s Warrants and the Company
shall hold such aggregate nominal amount in trust and shall apply it as applicable in connection with exercises of the Warrants
pursuant to Section 2(c) therein by such Purchaser or any assignee of the Warrants. Upon the exercise of the Warrants other than
pursuant to Section 2(c) therein by such Purchaser or any assignee of the Warrants or upon the termination of the Warrants prior
to exercise of all or any portion of such Warrants, the Company shall return to the Purchaser the applicable portion of the aggregate
nominal amount of the Ordinary Shares in connection with such Warrants that have been exercised other than pursuant to Section
2(c) therein on a periodic six (6) month basis or promptly upon request by the Purchaser and, upon termination of the Warrants
prior to exercise of all or any portion of such Warrants, the Company shall promptly return to the Purchaser in full the remaining
amount of the aggregate nominal amount of the Ordinary Shares in connection with such Warrants or promptly upon request by the
Purchaser. Notwithstanding the foregoing, each Purchaser shall have the right, upon three (3) Trading Days notice to the Company,
to require the Company to return the remaining amount of the aggregate nominal amount of the Ordinary Shares issuable upon exercise
of such Purchaser’s Warrants that was paid by such Purchaser, provided that any future exercise of the Warrants pursuant
to Section 2(c) therein by such Purchaser shall require delivery of such aggregate nominal amount of the Ordinary Shares before
the Warrant Shares are issued.


 


4.10         
Listing of Ordinary Shares. The Company hereby agrees to use commercially reasonable best efforts to maintain the
listing or quotation of the Ordinary Shares on the Trading Market on which the Ordinary Shares are currently listed, and concurrently
with the Closing, the Company shall apply to list or quote all of the Shares and Warrant Shares on such Trading Market and promptly
secure the listing of all of the Shares and Warrant Shares on such Trading Market. The Company further agrees, if the Company applies
to have the Ordinary Shares traded on any other Trading Market, it will then include in such application all of the Shares and
Warrant Shares, and will take such other action as is necessary to cause all of the Shares and Warrant Shares to be listed or quoted
on such other Trading Market as promptly as possible. The Company will then take all action reasonably necessary to continue the
listing and trading of its Ordinary 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 Ordinary 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         
Reserved.


 


4.12         
Subsequent Equity Sales.


 


(a)       From
the date hereof until ninety (90) days after the Closing Date, neither the Company nor any Subsidiary shall issue, enter into any
agreement to issue or announce the issuance or proposed issuance of Ordinary Shares or Ordinary Share Equivalent.


 


(b)       From
the date hereof until six (6) months after the Closing Date, the Company shall be prohibited from effecting or entering into an
agreement to effect any issuance by the Company or any of its Subsidiaries of Common Stock or Common Stock Equivalents (or a combination
of units thereof) involving a Variable Rate Transaction; provided, however, that, following ninety (90) days after
the Closing Date, the prohibition in this sentence shall not apply to the issuance of Ordinary Shares in an “at the market”
offering pursuant to the Company’s existing sales agreement with Jeffries LLC as sales agent or a sales agreement with H.C.
Wainwright & Co., LLC as sales agent. “Variable Rate Transaction” means a transaction in which the Company
(i) issues or sells any debt or equity securities that are convertible into, exchangeable or exercisable for, or include the right
to receive additional shares of Common Stock either (A) at a conversion price, exercise price or exchange rate or other price that
is based upon and/or varies with the trading prices of or quotations for the shares of Common Stock at any time after the initial
issuance of such debt or equity securities, or (B) with a conversion, exercise or exchange price that is subject to being reset
at some future date after the initial issuance of such debt or equity security or upon the occurrence of specified or contingent
events directly or indirectly related to the business of the Company or the market for the Common Stock or (ii) enters into, or
effects a transaction under, any agreement, including, but not limited to, an equity line of credit, whereby the Company may issue
securities at a future determined price. Any Purchaser shall be entitled to obtain injunctive relief against the Company to preclude
any such issuance, which remedy shall be in addition to any right to collect damages


 


(c)       Notwithstanding
the foregoing, this Section 4.12 shall not apply in respect of an Exempt Issuance, except that no Variable Rate Transaction shall
be an Exempt Issuance.


 


4.13         
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 the Transaction Documents. 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.


 






    28


     


    

 


4.14         
Certain Transactions and Confidentiality. Each Purchaser, severally and not jointly with the other Purchasers, covenants
that neither it nor any Affiliate acting on its behalf or pursuant to any understanding with it will execute any purchases or
sales, including Short Sales of any of the Company’s securities during the period commencing with the execution of this
Agreement and ending at such time that the transactions contemplated by this Agreement are first publicly announced pursuant
to the initial press release as described in Section 4.4.  Each Purchaser, severally
and not jointly with the other Purchasers, covenants that until such time as the transactions contemplated by this Agreement are
publicly disclosed by the Company pursuant to the initial press release as described in Section 4.4, such Purchaser will maintain
the confidentiality of the existence and terms of this transaction.  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.


 


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

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. Except as expressly set forth in the Transaction Documents to the contrary, each party shall

pay, or procure payment of, all Transfer Agent fees (including, without limitation, any fees required for same-day processing
of any instruction letter delivered by the Company and any exercise notice delivered by a Purchaser) stamp taxes and other taxes
and duties levied in connection with the delivery of any Securities to the Purchasers pursuant to this Agreement.

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

and permitted assigns. The Company may not assign this Agreement or any rights or obligations hereunder without the prior written
consent of each Purchaser (other than by merger). Any Purchaser may assign any or all of its rights under this Agreement to any
Person to whom such Purchaser assigns or transfers any Securities, provided that such transferee agrees in writing to be bound,
with respect to the transferred Securities, by the provisions of the Transaction Documents that apply to the “Purchasers”,
provided that, in connection with any such assignment of any rights under this Agreement prior to the Closing Date (other than
any assignment to an Affiliate of such Purchaser, for which no consent shall be required), such assignment shall require the prior
written consent of the Company, which consent shall not be unreasonably withheld.


 


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


 


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 4.8, the prevailing party in such Action or Proceeding shall be reimbursed by the non-prevailing party for its reasonable
attorneys’ fees and other costs and expenses incurred with the investigation, preparation and prosecution of such Action
or Proceeding.


 


5.10         
Survival. The representations and warranties contained herein shall survive the Closing and the delivery of the Shares
for two (2) years following the Closing Date.


 






    31


     


    

 



  


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


 


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


 


5.13         
Rescission and Withdrawal Right. Notwithstanding anything to the contrary contained in (and without limiting any
similar provisions of) any of the other Transaction Documents, whenever any Purchaser exercises a right, election, demand or option
under a Transaction Document and the Company does not timely perform its related obligations within the periods therein provided,
then such Purchaser may rescind or withdraw, in its sole discretion from time to time upon written notice to the Company, any relevant
notice, demand or election in whole or in part without prejudice to its future actions and rights; provided, however,
that, in the case of a rescission of an exercise of a Warrant, the applicable Purchaser shall be required to return any Ordinary
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).


 


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.


 






    32


     


    

 


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 the legal counsel of the Placement
Agent. The legal counsel of the Placement Agent does not represent any of the Purchasers and only represents the Placement Agent.
The Company has elected to provide all Purchasers with the same terms and Transaction Documents for the convenience of the Company
and not because it was required or requested to do so by any of the Purchasers. It is expressly understood and agreed that each
provision contained in this Agreement and in each other Transaction Document is between the Company and a Purchaser, solely, and
not between the Company and the Purchasers collectively and not between and among the Purchasers.


 


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


 


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


 






    33


     


    

 


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 Ordinary Shares in any Transaction Document shall be subject
to adjustment for reverse and forward share splits, share dividends, share combinations and other similar transactions of the Ordinary
Shares that occur after the date of this Agreement.


 


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