This Warrant Agreement
made as of [___________], 2016, is between BioLight Life Sciences Ltd., an Israeli company, with offices at Kiryat Atidim Building
3, 5th Floor, Tel Aviv 6158101, Israel (the “Company”), and VStock Transfer, LLC, with offices at
18 Lafayette Place, Woodmere, New York 11598 (the “Warrant Agent”).


 


WHEREAS, the Company
has determined to issue and deliver up to [_________] warrants (the “Warrants”) to investors, each Warrant evidencing
the right of the holder thereof to purchase one ordinary share, NIS 2.5 par value per share (the “Ordinary Shares”),
for $[___] of the Company, subject to adjustment as described herein.


 


WHEREAS, the Company
desires the Warrant Agent to act on behalf of the Company, and the Warrant Agent is willing to so act, in connection with the issuance,
registration, transfer, exchange, redemption and exercise of the Warrants;


 


WHEREAS, the Company
desires to provide for the form and provisions of the Warrants, the terms upon which they shall be issued and exercised, and the
respective rights, limitation of rights and immunities of the Company, the Warrant Agent and the holders of the Warrants; and


 


WHEREAS, all acts and
things have been done and performed which are necessary to make the Warrants, when executed on behalf of the Company and countersigned
by or on behalf of the Warrant Agent, as provided herein, the legally valid and binding obligations of the Company, and to authorize
the execution and delivery of this Warrant Agreement.


 


NOW, THEREFORE, in
consideration of the mutual agreements herein contained, the parties hereto agree as follows:


 


1.           Appointment
of Warrant Agent. The Company hereby appoints the Warrant Agent to act as agent for the Company for the Warrants, and the Warrant
Agent hereby accepts such appointment and agrees to perform the same in accordance with the terms and conditions set forth in this
Agreement.


 


2.           Warrants.


 


2.1           Form
of Warrant. Each Warrant shall be (a) issued in registered form only, (b) in substantially the form of Exhibit A
attached hereto, the provisions of which are incorporated herein, (c) signed by, or bear the facsimile or electronic
signature of, any two of the Chairman of the Board, the Chief Executive Officer, and the Chief Financial Officer of
the Company, and (d) signed by the Warrant Agent. In the event  that a person whose facsimile signature has been placed upon
any Warrant shall have ceased to serve in the capacity in which such person signed the Warrant before such Warrant is issued,
it may be issued with the same effect as if he or she had not ceased to be such at the date of issuance.


 


2.2           Effect
of Countersignature. Unless and until countersigned by the Warrant Agent pursuant to this Agreement, a Warrant shall be invalid
and of no effect and may not be exercised by the holder thereof. Warrant certificates shall be dated the date of countersignature
by the Warrant Agent.


 




     

     

    

  


2.3         Registration.



 


2.3.1           Warrant
Register. The Warrant Agent shall maintain books (“Warrant Register”), for the registration of the original
issuance and transfers of the Warrants. Upon the initial issuance of the Warrants, the Warrant Agent shall issue and register the
Warrants in the names of the respective holders thereof in such denominations and otherwise in accordance with instructions delivered
to the Warrant Agent by the Company.


 


2.3.2           Registered
Holder. Prior to due presentment for registration of transfer of any Warrant, the Company and the Warrant Agent may deem and
treat the person in whose name such Warrant shall be registered upon the Warrant Register (“Registered Holder”),
as the absolute owner of such Warrant and of each Warrant represented thereby (notwithstanding any notation of ownership or other
writing on the warrant certificate made by anyone other than the Company or the Warrant Agent), for the purpose of any exercise
thereof, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary.


 


3.           Terms
and Exercise of Warrants.


 


3.1          Exercise
Price. Each Warrant shall entitle the Holder, subject to the provisions of the applicable Warrant Certificate and of this Warrant
Agreement, to purchase from the Company the number of Ordinary Shares stated therein, at the price of US$___ per Ordinary Share,
subject to the subsequent adjustments provided in Section 4 hereof. The term “Exercise Price” as used in this
Warrant Agreement refers to the price per share at which Ordinary Shares may be purchased at the time a Warrant is exercised. 


 


3.2          Duration
of Warrants. A Warrant may be exercised only during the period (“Exercise Period”) commencing on the date
of issuance. For purposes of this Warrant Agreement, the “Expiration Date” shall have the meaning set forth

and all rights in respect thereof under this Agreement shall cease at the close of business on the Expiration Date. 


 


3.3          Exercise
of Warrants.


 


3.3.1           Payment.

the office of the Warrant Agent [____________] which may be done by fax or email delivery, and (ii) by paying to the Company in
full the Exercise Price for each whole Ordinary Share as to which the Warrant is exercised, in lawful money of the United States,
by wire transfer or in good certified check or good bank draft payable to the order of the Company.  In no event shall

[_________________]


 


3.3.2           Issuance
of Ordinary Shares. Assuming the exercise notice has been delivered and funds to pay
in full the Exercise Price are paid, each in accordance with Section 3.3.1,
then on or before the third trading day following the date upon which (1) the Warrant Agent has received an exercise notice for a Warrant and (2) the Company has received the funds in full,
the Company shall cause its transfer agent to (i) provided that the transfer agent is participating in The Depository Trust Company
(“DTC”) Fast Automated Securities Transfer Program, credit such aggregate number of Ordinary Shares to which
the Holder is entitled pursuant to such exercise to the Holder’s or its designee’s balance account with DTC through
its Deposit/Withdrawal at Custodian System, or (ii) if the transfer agent is not participating in the DTC Fast Automated Securities
Transfer Program, issue and deliver to the Holder, or at the Holder’s instruction pursuant to the delivered exercise notice,
the Holder’s agent or designee, in each case pursuant to this clause (ii), sent by reputable overnight courier to the address
specified in the applicable exercise notice, a certificate, registered in the Company’s share register in the name of the
Holder or its designee (as indicated in the applicable exercise notice), for the number of Ordinary Shares to which the Holder
is entitled pursuant to such exercise. 


 


3.3.3           Valid Issuance. All Ordinary Shares issued upon the proper exercise or surrender
of a Warrant in conformity with this Agreement shall be validly issued, fully paid and nonassessable.


 


3.3.4           Date
of Issuance. Each person or entity in whose name any such certificate for Ordinary Shares is issued shall, for all purposes,
be deemed to have become the holder of record of such shares on the date on which the Warrant was surrendered and payment of the
Exercise Price was made, irrespective of the date of delivery of such certificate, except that, if the date of such surrender and
payment is a date when the share transfer books of the Company are closed, such person shall be deemed to have become the holder
of such shares at the close of business on the next succeeding date on which the share transfer books are open.


 




    	 	3	 



     

    

  


3.4           Beneficial
Ownership Limitation on Exercises. The Company shall not affect the exercise of any portion of a Warrant, and the Registered
Holder of such Warrant shall not have the right to exercise any portion of such Warrant, to the extent that after giving effect
to such exercise, the Registered Holder (together with the Registered Holder’s affiliates, and any persons acting as a group
together with the Registered Holder or any Registered Holder’s affiliates) would beneficially own in excess of 4.99% (the
“Maximum Percentage”) of the Ordinary Shares outstanding immediately after giving effect to such exercise, provided, however,
that the foregoing limitation on exercise shall not apply to any Registered Holder who, together with such Registered Holder’s
affiliates, and any persons acting as a group together with such Registered Holder and such Registered Holder’s affiliates,
owns in excess of the Maximum Percentage immediately prior to the closing of the Offering.  For purposes of the foregoing
sentence, the aggregate number of Ordinary Shares beneficially owned by such Registered Holder and its affiliates shall include
the number of Ordinary Shares issuable upon exercise of a Warrant with respect to which the determination of such sentence is being
made, but shall exclude Ordinary Shares which would be issuable upon (i) exercise of the remaining, unexercised portion of such
Warrant beneficially owned by the Registered Holder and its affiliates and (ii) exercise or conversion of the unexercised or unconverted
portion of any other securities of the Company beneficially owned by the Registered Holder and its affiliates (including, without
limitation, any convertible notes or convertible preferred shares or warrants) subject to a limitation on conversion or exercise
analogous to the limitation contained herein beneficially owned by the Registered Holder or any of its affiliates.  Except
as set forth in the preceding sentence, for purposes of this paragraph, beneficial ownership shall be calculated in accordance
with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).  To the
extent that the limitation contained in this Section 3.4 applies, the Registered Holder’s submission of an Election to Purchase
shall be deemed to be the Registered Holder’s determination of whether a Warrant is exercisable (in relation to any other
securities owned by the Registered Holder together with any affiliates) and of which portion of a Warrant is exercisable, in each
case subject to the Maximum Percentage, and the Company shall have no obligation to verify or confirm the accuracy of such determination.  In
addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of
the Exchange Act and the rules and regulations promulgated thereunder.  For purposes of the Warrants, in determining
the number of outstanding Ordinary Shares, the Registered Holder may rely on the number of outstanding Ordinary Shares as reflected
in the most recent of (1) the Company’s most recent Form 20-F, Form 6-K or other public filing with the Commission, as the
case may be, (2) a more recent public announcement by the Company or (3) any other notice by the Company or its transfer agent
setting forth the number of Ordinary Shares outstanding.  For any reason at any time, upon the written or oral request
of the Registered Holder, the Company shall within three (3) trading days confirm to the Registered Holder the number of Ordinary
Shares then outstanding.  In any case, the number of outstanding Ordinary Shares shall be determined after giving effect
to the conversion or exercise of securities of the Company, including any Warrant, by the Registered Holder and its affiliates
since the date as of which such number of outstanding Ordinary Shares was reported.  By written notice to the Company,
the Registered Holder may from time to time increase or decrease the Maximum Percentage to any other percentage of the number of
Ordinary Shares outstanding immediately after giving effect to the issuance of Ordinary Shares upon exercise of a Warrant and the
provisions of this Section 3.4 shall continue to apply; provided that (i) any such increase will not be effective until the sixty-first
(61st) day after such notice is delivered to the Company, and (ii) any such increase or decrease will apply only to that Registered
Holder.  For purposes of clarity, the Ordinary Shares underlying any Warrant in excess of the Maximum Percentage for
a Registered Holder shall not be deemed to be beneficially owned by that Registered Holder for any purpose including for purposes
of Section 13(d) or Rule 16a-1(a)(1) of the Exchange Act.  The provisions of this paragraph shall be construed and implemented
in a manner otherwise than in strict conformity with the terms of this Section 3.4 to the extent necessary to correct this paragraph
(or any portion hereof) which may be defective or inconsistent with the intended beneficial ownership limitation herein contained
or to make changes or supplements necessary or desirable to properly give effect to such limitation.

4.           Adjustments.


 


4.1          Share
Dividends


 


4.1.1           Split-Ups. 
If after the date hereof, and subject to the provisions of Section 4.5 below, the number of outstanding Ordinary Shares is
increased by a share dividend payable in Ordinary Shares, or by a split-up of Ordinary Shares or other similar event, then, on
the effective date of such share dividend, split-up or similar event, the number of Ordinary Shares issuable on exercise of each
Warrant shall be increased in proportion to such increase in the outstanding Ordinary Shares and the Exercise Price shall be proportionally
decreased such that the aggregate Exercise Price, after such adjustments, remains the same for each Warrant.


 


4.1.2           Dividends
and Other Distributions. If the Company shall declare or make any dividend or other distribution of its assets (or rights to
acquire its assets) to holders of Ordinary Shares, by way of return of capital or otherwise (including, without limitation, any
distribution of cash, shares or other securities, property or options by way of a dividend, spin off, reclassification, corporate
rearrangement, scheme of arrangement or other similar transaction), except to the extent an adjustment was already made pursuant
to Section 4.1.1 or 4.2 (a “Distribution”), at any time after the issuance of a Warrant, then, in each such
case, the Company shall reserve and put aside the maximum Distribution amount the Registered Holder would have been entitled to
receive if the Registered Holder had held the number Ordinary Shares acquirable upon complete exercise of such Warrant immediately
before the date on which a record is taken for such Distribution, or, if no such record is taken, the date as of which the record
holders of Ordinary Shares are to be determined for the participation in such Distribution. Upon exercise of a Warrant, in whole
or in part, the Company shall, contemporaneously with the delivery of the Ordinary Shares, distribute to the Registered Holder
a pro rata portion of such Distribution based on the portion of the Warrant that has been exercised (provided, however,
to the extent that the Registered Holder’s right to participate in any such Distributions would result in the Registered
Holder exceeding the Maximum Percentage, then the Registered Holder shall not be entitled to participate in such Distribution at
such time and to such extent (or the beneficial ownership of any such Ordinary Shares as a result of such Distribution to such
extent) and such Distribution to such extent shall be held in abeyance for the benefit of the Registered Holder until such time,
if ever, as its right thereto would not result in the Registered Holder exceeding the Maximum Percentage, at which time or times
the Registered Holder shall be granted such Distribution (and any Distributions declared or made on such initial Distribution or
on any subsequent Distribution to be held similarly in abeyance) to the same extent as if there had been no such limitation).


 




    	 	5	 



     

    

  


4.2           Aggregation
of Shares. If after the date hereof, and subject to the provisions of Section 4.4
hereof, the number of outstanding Ordinary Shares is decreased by a consolidation, combination, reverse share split or reclassification
of Ordinary Shares or other similar event, then, on the effective date of such consolidation, combination, reverse share split,
reclassification or similar event, the number of Ordinary Shares issuable on exercise of each Warrant shall be decreased in proportion
to such decrease in outstanding Ordinary Shares and the Exercise Price shall be proportionally increased such that the aggregate
Exercise Price, after such adjustments, remains the same for each Warrant.


 


4.3           Purchase
Rights. If at any time the Company grants, issues or sells any options, convertible securities
or rights to purchase shares, warrants, securities or other property pro rata to the record holders of Ordinary Shares (the “Purchase
Rights”), then the Registered Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights,
the aggregate Purchase Rights which the Registered Holder could have acquired if the Registered Holder had held the number of Ordinary
Shares acquirable upon complete exercise of a Warrant immediately before the date on which a record is taken for the grant, issuance
or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of Ordinary Shares are
to be determined for the grant, issue or sale of such Purchase Rights (provided, however, to the extent that
the Registered Holder’s right to participate in any such Purchase Right would result in the Registered Holder exceeding the
Maximum Percentage, then the Registered Holder shall not be entitled to participate in such Purchase Right to such extent (or beneficial
ownership of such Ordinary Shares as a result of such Purchase Right to such extent) and such Purchase Right to such extent shall
be held in abeyance for the Registered Holder until such time, if ever, as its right thereto would not result in the Registered
Holder exceeding the Maximum Percentage, at which time or times the Registered Holder shall be granted such right (and any Purchase
Right granted, issued or sold on such initial Purchase Right or on any subsequent Purchase Right to be held similarly in abeyance)
to the same extent as if there had been no such limitation).


 




    	 	6	 



     

    

  


4.4           Fundamental
Transactions. If, at any time while the Warrants are outstanding, (i) the Company,
directly or indirectly, in one or more related transactions effects any merger or consolidation of the Company with or into
another person, in which the Company is not the surviving entity or the shareholders of the Company immediately prior to such
merger or consolidation do not own, directly or indirectly, a majority of the outstanding voting securities of the
surviving entity, (ii) the Company, directly or indirectly, effects any sale, lease, license, assignment, transfer,
conveyance or other disposition of all or substantially all of its assets in one or a series of related transactions, (iii)
any, direct or indirect, purchase offer, tender offer or exchange offer (whether by the Company or another person) is
completed pursuant to which holders of Ordinary Shares are permitted to sell, tender or exchange their shares for other
securities, cash or property and has been accepted by the holders of 50% or more of the outstanding Ordinary Shares, (iv) the
Company, directly or indirectly, in one or more related transactions effects any reclassification, reorganization or
recapitalization of the Ordinary Shares or any compulsory share exchange pursuant to which the Ordinary Shares are
effectively converted into or exchanged for other securities, cash or property (other than as a result of a subdivision or
combination of Ordinary Shares covered by Section 4.1 above), or (v) the Company, directly or indirectly, in one or more
related transactions consummates a stock or share purchase agreement or other business combination (including, without
limitation, a reorganization, recapitalization, spin-off or scheme of arrangement) with another person or group of persons
whereby such other person or group acquires more than 50% of the outstanding Ordinary Shares (not including any Ordinary
Shares held by the other person or other persons making or party to, or associated or affiliated with the other persons
making or party to, such stock or share purchase agreement or other business combination) (each, a
“Fundamental Transaction”), then, upon any subsequent exercise of a Warrant, the Registered Holder of such
Warrant shall be entitled to receive, for each Ordinary Share that would have been issuable upon such exercise immediately
prior to the occurrence of such Fundamental Transaction (without regard to any limitation in Section 3.4 on the exercise of
the Warrants), the number of Ordinary Shares of the successor or acquiring corporation or of the Company, if it is the
surviving corporation, and any additional consideration (the “Alternate Consideration”) which, in all
cases, was received as a result of such Fundamental Transaction by a holder of the number of Ordinary Shares for which a
Warrant is exercisable immediately prior to such Fundamental Transaction (without regard to any limitation in Section 3.4 on
the exercise of the Warrants). If holders of Ordinary Shares are given any choice as to the securities, cash or property to
be received in a Fundamental Transaction, then each Registered Holder shall be given the same choice as to the
Alternate Consideration. Notwithstanding anything to the contrary, (a) if the holders of Ordinary Shares received, as a
result of such Fundamental Transaction, a consideration or Alternate Consideration (whether from the Company or from any
other person, and whether such consideration or Alternate Consideration is comprised of cash, securities or other property)
(such consideration attributed to one Ordinary Share: the "Fundamental Transaction Consideration Per Ordinary
Share") with respect to some but not all of their Ordinary Shares (including in the event that they have tendered
only some of the Ordinary Shares which such shareholders have initially requested to tender) then, upon any subsequent
exercise of a Warrant, the Registered Holder of such Warrant shall be entitled to receive such consideration on a pro-rata
basis, based on the number of Ordinary Shares underlying its Warrant; and (b) in the event that the Fundamental Transaction
Consideration Per Ordinary Share paid as a result of such Fundamental Transaction is paid by the Successor Entity (as defined
below) or by any other person other than the Company, then such Successor Entity or the other person shall assume and be
responsible to pay the Fundamental Transaction Consideration Per Ordinary Share upon any subsequent exercise of a
Warrant.  The Company shall cause any successor entity in a Fundamental Transaction in which the Company is not the
survivor (the “Successor Entity”) to assume in writing all obligations of the Company under each Warrant
in accordance with the provisions of this Section 4.4 pursuant to agreements in form and substance reasonably satisfactory
to the Registered Holders and approved by the Registered Holder (without unreasonable delay) prior to such
Fundamental Transaction and shall, at the option of each Registered Holder, deliver to such Registered Holder in exchange for
such Registered Holder’s Warrant a written instrument substantially similar in form and substance to such
Registered Holder’s Warrant which is exercisable for a corresponding number of shares of capital stock of such
Successor Entity (or its parent entity) equivalent to the Ordinary Shares acquirable and receivable upon exercise of such
Warrant (without regard to the limitations on exercise set forth in Section 3.4) prior to such Fundamental Transaction, and
with an exercise price which applies the Exercise Price hereunder to such shares of capital stock (but taking into account
the relative value of the Ordinary Shares pursuant to such Fundamental Transaction and the value of such shares of capital
stock, such number of shares of capital stock and such exercise price being for the purpose of protecting the economic value
of such Warrant immediately prior to the consummation of such Fundamental Transaction). Upon the occurrence of any such
Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that from and after the date of
such Fundamental Transaction, the provisions of this Agreement and each Warrant referring to the “Company” shall
refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the
obligations of the Company under this Agreement and each Warrant with the same effect as if such Successor Entity had been
named as the Company herein.


 




    	 	7	 



     

    

  


4.5           Calculations.
All calculations under this Section 4 shall be made to the nearest cent or the nearest
whole share, as the case may be. For purposes of this Section 4, any calculation of the number of Ordinary Shares deemed to
be issued and outstanding as of a given date shall not include treasury shares, if any. In any case in which this Section 4
shall require that an adjustment in the Exercise Price be made effective as of a record date for a specified event, if the
Registered Holder exercises a Warrant after such record date, the Company may elect to defer, until the occurrence of such
event, the issuance of the Ordinary Shares and other share capital of the Company in excess of the Ordinary Shares and other
share capital of the Company, if any, issuable upon such exercise on the basis of the Exercise Price in effect prior to such
adjustment; provided, however, that in such case the Company or the Warrant Agent shall deliver to
the Registered Holder a due bill or other appropriate instrument evidencing the Registered Holder’s right to receive
such additional shares and/or other capital securities upon the occurrence of the event requiring such
adjustment.


 


4.6           Notices
of Changes in Warrant. Upon every adjustment of the Exercise Price or the number of shares issuable upon exercise of a Warrant,
the Company shall give written notice thereof to the Warrant Agent, which notice shall state the Exercise Price resulting from
such adjustment and the increase or decrease, if any, in the number of shares purchasable at such price upon the exercise of a
Warrant, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. Upon
the occurrence of any such adjustment the Company shall give written notice to each Registered Holder, at the last address set
forth for such holder in the Warrant Register, of the record date or the effective date of the event. Failure to give such notice,
or any defect therein, shall not affect the legality or validity of such event. 


 


4.7           No
Fractional Shares. Notwithstanding any provision contained in this Warrant Agreement to the contrary, the Company shall not
issue fractional shares upon exercise of Warrants. If, by reason of any adjustment made pursuant to this Section 4, the holder
of any Warrant would be entitled, upon the exercise of such Warrant, to receive a fractional interest in a share, the Company
shall, upon such exercise, round up to the nearest whole number the number of the Ordinary Shares to be issued to the Warrant holder.


 


4.8           Form
of Warrant. The form of Warrant need not be changed because of any adjustment pursuant to this Section 4, and Warrants issued
after such adjustment may state the same Exercise Price and the same number of shares as is stated in the Warrants initially issued
pursuant to this Agreement. However, the Company may, at any time, in its sole discretion, make any change in the form of Warrant
that the Company may deem appropriate and that does not affect the substance thereof, and any Warrant thereafter issued or countersigned,
whether in exchange or substitution for an outstanding Warrant or otherwise, may be in the form as so changed.


 


4.9           Other
Events. In case any event shall occur affecting the Company as to which none of the provisions
of preceding subsections of this Section 4 are strictly applicable, but which would require an adjustment to the terms
of the Warrants in order to (i) avoid an adverse impact on the Warrants and (ii) effectuate the intent and purpose of
this Section 4, then, in each such case, the Company shall appoint a firm of independent public accountants, investment banking
or other appraisal firm of recognized national standing, which shall give its opinion as to whether or not any adjustment to the
rights represented by the Warrants is necessary to effectuate the intent and purpose of this Section 4 and, if they determine
that an adjustment is necessary, the terms of such adjustment. The Company shall adjust the terms of the Warrants in a manner that
is consistent with any adjustment recommended in such opinion.


 




    	 	8	 



     

    

  


5.           Transfer
and Exchange of Warrants.


 


5.1           Registration
of Transfer. The Warrant Agent shall register the transfer, from time to time, of any outstanding Warrant into the Warrant
Register, upon surrender of such Warrant for transfer, properly endorsed with signatures properly guaranteed and accompanied by
appropriate instructions for transfer. Upon any such transfer, a new Warrant representing an equal aggregate number of Warrants
shall be issued and the old Warrant shall be cancelled by the Warrant Agent. The Warrants so cancelled shall be delivered by the
Warrant Agent to the Company from time to time upon the Company’s request.


 


5.2           Procedure
for Surrender of Warrants. Warrants may be surrendered to the Warrant Agent, together with a written request for exchange or
transfer, and, thereupon, the Warrant Agent shall issue in exchange therefor one or more new Warrants as requested by the Registered
Holder of the Warrants so surrendered, representing an equal aggregate number of Warrants; provided, however, that, in the event
a Warrant surrendered for transfer bears a restrictive legend, the Warrant Agent shall not cancel such Warrant and shall issue
new Warrants in exchange therefor until the Warrant Agent has received an opinion of counsel for the Company stating that such
transfer may be made and indicating whether the new Warrants must also bear a restrictive legend.


 


5.3           Fractional
Warrants. The Warrant Agent shall not be required to effect any registration of transfer or exchange which will result in the
issuance of a warrant certificate for a fraction of a warrant.


 


5.4           Warrant
Execution and Countersignature. The Warrant Agent is hereby authorized to countersign and to deliver, in accordance with the
terms of this Agreement, the Warrants required to be issued pursuant to the provisions of this Section 5, and the Company, whenever
required by the Warrant Agent, will supply the Warrant Agent with Warrants duly executed on behalf of the Company for such purpose.


 


6.           Other
Provisions Relating to Rights of Registered Holders of Warrants.


 


6.1           No
Rights as Shareholder. A Warrant does not entitle the Registered Holder thereof to any of the rights of a shareholder of the
Company, including, without limitation, the right to receive dividends, or other distributions, exercise any preemptive rights
to vote or to consent or to receive notice as shareholders in respect of the meetings of shareholders or the election of directors
of the Company or any other matter.


 




    	 	9	 



     

    

  


6.2           Lost,
Stolen Mutilated or Destroyed Warrants. If any Warrant is lost, stolen, mutilated or destroyed, the Company and the Warrant
Agent may, on such terms as to indemnity or otherwise as they may in their discretion impose (which terms shall, in the case of
a mutilated Warrant, include the surrender thereof), issue a new Warrant of like denomination, tenor and date as the Warrant so
lost, stolen, mutilated or destroyed. Any such new Warrant shall constitute a substitute contractual obligation of the Company,
whether or not the allegedly lost, stolen, mutilated or destroyed Warrant shall be at any time enforceable by anyone.


 


6.3           Reservation
of Ordinary Shares. The Company shall at all times reserve and keep available a number of its authorized but unissued Ordinary
Shares that will be sufficient to permit the exercise in full of all outstanding Warrants issued pursuant to this Warrant Agreement.


 


6.4           Registration
of the Ordinary Shares. The Company registered the Warrants and the Ordinary Shares underlying
the Warrants in the Registration Statement. The Company will use its reasonable efforts to maintain the effectiveness of such Registration
Statement and the current status of the Prospectus or to file and maintain the effectiveness of another registration statement
and another current prospectus covering the Ordinary Shares issuable upon exercise of the Warrants at any time that the Warrants
are exercisable.  In addition, the Company agrees to use its reasonable best efforts to register such Ordinary Shares
under the blue sky laws of the states of residence of the exercising Warrant holders to the extent an exemption from such registration
is not available. 


 


7.           Concerning
the Warrant Agent and Other Matters. 


 


7.1           Payment
of Taxes. The Company shall not be required to pay any stamp or other tax or charge required to be paid in connection
with the exercise of Warrants; and the Company shall not be required to issue or deliver any Ordinary  Shares until such tax
or other charge shall have been paid or it has been established to the Company’s and the Warrant Agent’s
satisfaction that no such tax or other charge is due.


 


7.2           Resignation, Consolidation, or Merger of Warrant
Agent.


 




    	 	10	 



     

    

  


7.2.1           Appointment
of Successor Warrant Agent. The Warrant Agent, or any successor to it hereafter appointed, may resign its duties and be discharged
from all further duties and liabilities hereunder after giving sixty (60) days’ notice in writing to the Company. If the
office of the Warrant Agent becomes vacant by resignation or incapacity to act or otherwise, the Company shall appoint, in writing,
a successor Warrant Agent in place of the Warrant Agent. If the Company shall fail to make such appointment within a period of
thirty (30) days after it has been notified in writing of such resignation or incapacity by the Warrant Agent or by the holder
of the Warrant (who shall, with such notice, submit his, her or its Warrant for inspection by the Company), then the holder of
any Warrant may apply to the Supreme Court of the State of New York for the County of New York for the appointment of a successor
Warrant Agent. Any successor Warrant Agent, whether appointed by the Company or by such court, shall be an entity organized and
existing under the laws of the State of New York, in good standing and have its principal office in the Borough of Manhattan, City
and State of New York, and be authorized under such laws to exercise corporate trust powers and subject to supervision or examination
by federal or state authorities. After appointment, any successor Warrant Agent shall be vested with all the authority, powers,
rights, immunities, duties and obligations of its predecessor Warrant Agent with like effect as if originally named as Warrant
Agent hereunder, without any further act or deed; but, if for any reason it becomes necessary or appropriate, the predecessor Warrant
Agent shall execute and deliver, at the expense of the Company, an instrument transferring to such successor Warrant Agent all
the authority, powers, and rights of such predecessor Warrant Agent hereunder; and, upon request of any successor Warrant Agent,
the Company shall make, execute, acknowledge, and deliver any and all instruments in writing for more fully and effectually vesting
in and confirming to such successor Warrant Agent all such authority, powers, rights, immunities, duties and obligations.


 


7.2.2           Notice

or Consolidation of Warrant Agent. Any entity into which the Warrant Agent may be merged or with which it may be consolidated

Warrant Agent under this Warrant Agreement without any further act on the part of the Company or the Warrant Agent.

of Warrant Agent.

hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be
conclusively proved and established by a statement signed by the Chief Executive Officer, Chief Financial Officer or Chairman of
the Board of the Company and delivered to the Warrant Agent. The Warrant Agent may rely upon such statement for any action taken

Agent’s negligence, willful misconduct or bad faith.
