WARRANT AGENT AGREEMENT


 


WARRANT AGENT AGREEMENT (this “Warrant
Agreement”) dated as of ______, 2016 (the “Issuance Date”) between Cellect Biotechnology Ltd., a company
incorporated under the laws of the State of Israel (the “Company”), and The Bank of New York Mellon (the “Warrant
Agent”).


 


WHEREAS, pursuant to the terms of that
certain Underwriting Agreement (“Underwriting Agreement”), dated _______, 2016, between the Company and H.C.
Wainwright & Co., LLC (“Wainwright”), as representative of the underwriters set forth therein, the Company
is engaged in a public offering (the “Offering”) of up to _________ American Depositary Shares (“ADSs”),
each ADS representing 20 ordinary shares of the Company, no par value per share (“Ordinary Shares”), and up
to ________ Warrants (the “Warrants”), with each such Warrant representing the right of the holder thereof to
purchase one ADS (each, a “Warrant ADS”) for US$_____ per ADS, subject to adjustment as described herein, plus
applicable fees, charges and taxes;


 


WHEREAS, the ADSs are issuable under the
Deposit Agreement dated as of ___________, 2016 (the “Deposit Agreement”) among the Company, The Bank of New
York Mellon, as depositary (the “Depositary”), and all Owners and Holders (each as defined in the Deposit Agreement)
from time to time of the ADSs issued thereunder;


 


WHEREAS, the Company has filed with the
Securities and Exchange Commission (the “Commission”) a Registration Statement, No. 333-212432, on Form F-1
(as the same may be amended from time to time, the “Registration Statement”) for the registration, under the
Securities Act of 1933, as amended (the “Securities Act”), of, among other securities, the Warrants and the
Ordinary Shares underlying the Warrant ADSs issuable upon exercise of the Warrants (the “Warrant Shares”), and
such Registration Statement was declared effective on ________, 2016;


 


WHEREAS, the Company desires the Warrant
Agent to act on behalf of the Company, and the Warrant Agent is willing to so act, in accordance with the terms set forth in this
Warrant Agreement in connection with the issuance, registration, registration of transfer and exercise of the Warrants;


 


WHEREAS, the Company desires to provide
for the 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 the valid, binding and legal 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 with respect to the Warrants, and the Warrant Agent
hereby accepts such appointment and agrees to perform the same in accordance with the express terms and conditions set forth in
this Warrant Agreement (and no implied terms or conditions).


 


2. Warrants.


 


2.1 Form of Warrants. The Warrants
shall be registered securities and shall be evidenced by a global certificate (“Global Certificate”) in the
form of Annex A to this Warrant Agreement, which shall be deposited on behalf of the Company with a custodian for The Depository
Trust Company (“DTC”) and registered in the name of Cede & Co., a nominee of DTC. If DTC subsequently ceases
to make its book-entry settlement system available for the Warrants, the Company may instruct the Warrant Agent regarding making
other arrangements for book-entry settlement. In the event that the Warrants are not eligible for, or it is no longer necessary
to have the Warrants available in, book-entry form, the Company may instruct the Warrant Agent to provide written instructions
to DTC to deliver to the Warrant Agent for cancellation the Global Certificate, and the Company shall instruct the Warrant Agent
to deliver to DTC separate certificates evidencing Warrants (“Definitive Certificates” and, together with the
Global Certificate, “Warrant Certificates”) registered as requested through the DTC system.


 


2.1.1. Exchange of Interest in Global
Certificate for Definitive Certificate. Notwithstanding Section 2.1 above, a holder of a security entitlement in Warrants evidenced
by the Global Certificate has the right to elect at any time to exchange it for a Definitive Certificate evidencing the same number
of Warrants. Upon written notice by a Participant having Warrants credited to its DTC account for the exchange of some or all that
entitlement for a Definitive Certificate evidencing the same number of Warrants, which request shall be in the form attached hereto
as Annex D (a “Warrant Certificate Request Notice” and the date of delivery of such Warrant Certificate
Request Notice by the Holder, the “Warrant Certificate Request Notice Date” and the exchange made pursuant to
the Warrant Certificate Request Notice, a “Warrant Exchange”), and upon surrender by that Participant of the
Warrants to be exchanged to the Warrant Agent through DTC’s system, the Warrant Agent shall, without unreasonable delay,
effect the Warrant Exchange by issuing and delivering a Warrant Certificate for such number of Warrants in the name and mailed
to the address set forth in the Warrant Certificate Request Notice. Such Warrant Certificate shall be dated the original issue
date of the Warrants, shall be manually executed by an authorized signatory of the Company and shall be in the form attached hereto
as Exhibit A In connection with a Warrant Exchange, the Company agrees to deliver, or to direct the Warrant Agent to deliver,
the Warrant Certificate to the specified Holder within five (5) Business Days of the Warrant Certificate Request Notice pursuant
to the delivery instructions in the Warrant Certificate Request Notice (the “Warrant Certificate Delivery Date”).


 


2.2. Issuance and Registration of Warrants.


 


2.2.1. Warrant Register. The Warrant
Agent shall maintain books (“Warrant Register”) for the registration of original issuance and the registration
of transfer of the Warrants.


 


2.2.2. Issuance of Warrants. Upon
the initial issuance of the Warrants, the Warrant Agent shall issue the Global Certificate and deliver the Warrants in the DTC
book-entry settlement system in accordance with written instructions delivered to the Warrant Agent by the Company. Ownership of
security entitlements in the Warrants shall be shown on, and the transfer of such ownership shall be effected through, records
maintained (i) by DTC and (ii) by institutions that have accounts with DTC (each, a “Participant”).


 




     


     


    

  


2.2.3. Beneficial Owner; 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 that Warrant shall be registered on the Warrant Register (the “Holder”) as the absolute
owner of such Warrant for purposes 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. Notwithstanding the foregoing, nothing herein shall prevent the Company,
the Warrant Agent or any agent of the Company or the Warrant Agent from giving effect to any written certification, proxy or other
authorization furnished by DTC governing the exercise of the rights of a holder of a beneficial interest in any Warrant. The rights
of beneficial owners in a Warrant evidenced by the Global Certificate shall be exercised by the Holder or a Participant through
the DTC system, except to the extent set forth herein or in the Global Certificate.


 


2.2.4. Execution. The Warrant Certificates
shall be executed on behalf of the Company by any authorized officer of the Company (an “Authorized Officer”),
which need not be the same authorized signatory for all of the Warrant Certificates, either manually or by facsimile signature.
The Warrant Certificates shall be countersigned by an authorized signatory of the Warrant Agent, which need not be the same signatory
for all of the Warrant Certificates, and no Warrant Certificate shall be valid for any purpose unless so countersigned. In case
any Authorized Officer of the Company that signed any of the Warrant Certificates ceases to be an Authorized Officer of the Company
before countersignature by the Warrant Agent and issuance and delivery by the Company, such Warrant Certificates, nevertheless,
may be countersigned by the Warrant Agent, issued and delivered with the same force and effect as though the person who signed
such Warrant Certificates had not ceased to be such officer of the Company; and any Warrant Certificate may be signed on behalf
of the Company by any person who, at the actual date of the execution of such Warrant Certificate, shall be an Authorized Officer
of the Company authorized to sign such Warrant Certificate, although at the date of the execution of this Warrant Agreement any
such person was not such an Authorized Officer.


 


2.2.5. Registration of Transfer.
At any time at or prior to the Expiration Date (as defined below), a transfer of any Warrants may be registered and any Warrant
Certificate or Warrant Certificates may be split up, combined or exchanged for another Warrant Certificate or Warrant Certificates
evidencing the same number of Warrants as the Warrant Certificate or Warrant Certificates surrendered. Any Holder desiring to register
the transfer of Warrants or to split up, combine or exchange any Warrant Certificate shall make such request in writing delivered
to the Warrant Agent, and shall surrender to the Warrant Agent the Warrant Certificate or Warrant Certificates evidencing the Warrants
the transfer of which is to be registered or that is or are to be split up, combined or exchanged and, in the case of registration
of transfer, shall provide a signature guarantee. Thereupon, the Warrant Agent shall countersign and deliver to the person entitled
thereto a Warrant Certificate or Warrant Certificates, as the case may be, as so requested. The Company and the Warrant Agent may
require payment, by the Holder requesting a registration of transfer of Warrants or a split-up, combination or exchange of a Warrant
Certificate (but, for purposes of clarity, not upon the exercise of the Warrants and issuance of Warrant ADS to the Holder), of
a sum sufficient to cover any tax or governmental charge that may be imposed in connection with such registration of transfer,
split-up, combination or exchange, together with reimbursement to the Company and the Warrant Agent of all reasonable expenses
incidental thereto.


 




     


     


    

  


2.2.6. Loss, Theft and Mutilation of
Warrant Certificates. Upon receipt by the Company and the Warrant Agent of evidence reasonably satisfactory to them of the
loss, theft, destruction or mutilation of a Warrant Certificate, and, in case of loss, theft or destruction, of indemnity or security
in customary form and amount, and reimbursement to the Company and the Warrant Agent of all reasonable expenses incidental thereto,
and upon surrender to the Warrant Agent and cancellation of the Warrant Certificate if mutilated, the Warrant Agent shall, on behalf
of the Company, countersign and deliver a new Warrant Certificate of like tenor to the Holder in lieu of the Warrant Certificate
so lost, stolen, destroyed or mutilated. The Warrant Agent may charge the Holder an administrative fee for processing the replacement
of lost Warrant Certificates, which shall be charged only once in instances where a single surety bond obtained covers multiple
certificates. The Warrant Agent may receive compensation from the surety companies or surety agents for administrative services
provided to them.


 


2.2.7. Proxies. The Holder of a
Warrant may grant proxies or otherwise authorize any person, including the Participants and beneficial holders that may own interests
through the Participants, to take any action that a Holder is entitled to take under this Agreement or the Warrants; provided,
however, that at all times that Warrants are evidenced by a Global Certificate, exercise of those Warrants shall be effected
on their behalf by Participants through DTC in accordance the procedures administered by DTC.


 


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 ADSs stated therein, at the price of US$______ per ADS, 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 ADS
at which ADSs may be purchased at the time a Warrant is exercised. In addition to the Exercise Price, an exercising Holder must
pay to the Warrant Agent at the time of exercise the Depositary’s fee of up to US$0.05 per ADS for issuance of ADSs (the
“Issuance Fee”). The Exercise Price per ADS plus the Issuance Fee per ADS is referred to as the “Deposit
Amount”.


 


3.2. Duration of Warrants. Warrants
may be exercised only during the period (“Exercise Period”) commencing on the Issuance Date and terminating
at 5:00 P.M., New York City time (the “close of business”) on _________, 2021 (“Expiration Date”).
Each Warrant not exercised on or before the Expiration Date shall become void, and all rights thereunder and all rights in respect
thereof under this Warrant Agreement shall cease at the close of business on the Expiration Date.


 


3.3. Exercise of Warrants.


 


3.3.1. Exercise and Payment. (a)
Subject to the provisions of this Warrant Agreement, a Holder (or a Participant acting on behalf of a Holder in accordance with
DTC procedures) may exercise Warrants by delivering to the Warrant Agent, not later than 5:00 P.M., New York City time, on any
business day during the Exercise Period (i) the Warrants to be exercised by (A) surrender of the Warrant Certificate evidencing
the Warrants to the Warrant Agent at its office designated for such purpose or (B) delivery of the Warrants to an account of the
Warrant Agent at DTC designated for such purpose in writing by the Warrant Agent to DTC from time to time, (ii) an election to
purchase the Warrant ADSs underlying the Warrants to be exercised (A) in the form included in Annex B to this Warrant Agreement
or (B) via an electronic warrant exercise through the DTC system (each, an “Election to Purchase”) and (iii)
the Deposit Amount for each Warrant to be exercised (and, if applicable, any taxes or charges due in connection with the exercise
of such Warrants), in lawful money of the United States of America by (A) certified or official bank check payable to The Bank
of New York Mellon, (B) bank wire transfer in immediately available funds to The Bank of New York Mellon, 500 Ross Street, Pittsburgh,
PA 15262-00001, ABA #: 043-000-261, Account Number: 1361721, Account Name: Computershare Inc. AAF Client Corporate Actions, Ref:
Cellect Biotechnology Warrants, Swift Code MELNUS3P or (C) payment to the Warrant Agent through the DTC system.


 




     


     


    

  


(b) If any of (i) the Warrants, (ii) the
Election to Purchase, or (iii) the Deposit Amount therefor (and, if applicable, any taxes or charges due in connection with the
exercise of such Warrants), is received by the Warrant Agent on any date after 5:00 P.M., New York City time, or on a date that
is not a Trading Day, the Warrants with respect thereto will be deemed to have been received and exercised on the Trading Day next
succeeding such date. The “Exercise Date” will be the date on which the materials in the foregoing sentence
are received by the Warrant Agent (if by 5:00 P.M., New York City time), or the following Trading Day (if after 5:00 P.M., New
York City time), regardless of any earlier date written on the materials. If the Warrants are received or deemed to be received
after the Expiration Date, the exercise thereof will be null and void and any funds delivered to the Warrant Agent will be returned
to the Holder or Participant, as the case may be, as soon as practicable. In no event will interest accrue on any funds deposited
with the Warrant Agent in respect of an exercise or attempted exercise of Warrants. “Trading Day” means any
day on which the ADSs are traded on the Trading Market, or, if the Trading Market is not the principal trading market for the ADSs,
then on the principal securities exchange or securities market in the United States on which the ADSs are then traded, provided
that “Trading Day” shall not include any day on which the ADSs are scheduled to trade on such exchange or market for
less than 4.5 hours or any day that the ADSs are suspended from trading during the final hour of trading on such exchange or market
(or if such exchange or market does not designate in advance the closing time of trading on such exchange or market, then during
the hour ending at 4:00 P.M., New York City time). “Trading Market” means NYSE MKT, the Nasdaq Capital Market,
the Nasdaq Global Market, the Nasdaq Global Select Market or the New York Stock Exchange.


 


(c) The Warrant Agent shall deposit all
funds received by it in payment of the Exercise Price in the account of the Company maintained with the Warrant Agent for such
purpose and shall advise the Company via telephone at the end of each day on which funds for the exercise of the Warrants are received
of the amount so deposited to such account. The Warrant Agent shall promptly confirm such telephonic advice to the Company in writing.


 


(d) If less than all the Warrants evidenced
by a surrendered Warrant Certificate are exercised, the Warrant Agent shall split up the surrendered Warrant Certificate and return
to the Holder a Warrant Certificate evidencing the Warrants that were not exercised.


 


3.3.2. Issuance of Warrant Shares.
(a) The Warrant Agent shall, by 11:00 a.m., New York City time, on the Trading Day following the Exercise Date of any Warrant,
advise the Company, the transfer agent and registrar for Ordinary Shares and the Depositary, in respect of (i) the number of Warrant
Shares indicated on the Election to Purchase as issuable upon such exercise with respect to such exercised Warrants, (ii) the instructions
of the Holder or Participant, as the case may be, provided to the Warrant Agent with respect to the delivery of the Warrant ADSs
and the number of Warrants that remain outstanding after such exercise and (iii) such other information as the Company or the Depositary
shall reasonably request. The Warrant Agent shall pay the Depositary the Issuance Fee for the number of Warrant ADSs to be issued
out of the Deposit Amount it received.


 




     


     


    

  


(b) The Company shall, by no later than
5:00 P.M., New York City time, on the third Trading Day following the Exercise Date of any Warrant, provided the funds in payment
of the Exercise Price have cleared (such date and time, the “Delivery Time”), cause its registrar to deliver
the Warrant Shares issuable upon that exercise to the Depositary’s Israeli custodian for deposit under the Deposit Agreement
and instruct the Depositary to deliver the Warrant ADSs issuable upon that deposit of Warrant Shares as requested in the Election
to Purchase.


 


3.3.3. Valid Issuance. All Warrant
Shares issuable by the Company upon the proper exercise of a Warrant in conformity with this Warrant Agreement shall be validly
issued, fully paid and non-assessable.


 


3.3.4. No Fractional Exercise. No
fractional Warrant ADSs will be issued upon the exercise of the Warrant, but rather the Company shall adjust the number of Warrant
Shares issued up or down to the nearest integral multiple of the number of Ordinary Shares at the time represented by one ADS.


 


3.3.5 No Transfer 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 Warrant 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. For purposes of clarity, the Company shall pay any stamp or other tax or charge required to be paid in connection with any
issuance to the Holder of the Warrant ADSs or Warrant Shares upon the exercise of Warrants.


 


3.3.6 Date of Issuance. (a) The
Company will treat an exercising Holder as a beneficial owner of the Warrant Shares as of the Exercise Date, except that, if the
Exercise Date is a date when the stock transfer books of the Company are closed, such person shall be deemed to have become the
holder of such shares at the open of business on the next succeeding date on which the stock transfer books are open. However,
it is understood and agreed that Warrant ADSs will not be registered or issued until the Depositary receives notice from its custodian
that the Warrant Shares have been deposited under the Deposit Agreement; provided further, however, it is acknowledged and agreed
that the Company shall take all reasonable steps to ensure the Warrant ADSs are delivered to the Holder on or prior to the Delivery
Time in accordance with Section 3.3.2(b) hereof and, if the Warrant ADSs are not delivered to the Holder on or prior to the Delivery
Time, the provisions of Section 3.3.9 shall apply.


 


(b) Notwithstanding Section 3.3.6(a), the
Company will treat an exercising Holder, which Holder effected a Warrant Exchange pursuant to Section 2.1.1 prior to the Exercise
Date, as a beneficial owner of the Warrant Shares as of the Exercise Date, provided that the Warrant Agent receives the Deposit
Amount within one Trading Day of the Exercise Date. No exercising Holder, which Holder effected a Warrant Exchange pursuant to
Section 2.1.1 prior to the Exercise Date, shall be required to surrender its Warrant to the Warrant Agent, unless such exercise
is for the remaining numbers of ADSs issuable upon exercise of such Warrant, in which case the Holder shall deliver the Warrant
Certificate to the Warrant Agent within three (3) Business Days. For the purposes of this Section 3.3.6(b), “Exercise
Date” means the date on which the Warrant Agent receives the Election to Purchase from a Holder.


 




     


     


    

  


3.3.7 Restrictive Legend Events; Cashless
Exercise Under Certain Circumstances.


 


(i) The Company shall use it reasonable
best efforts to maintain the effectiveness of the Registration Statement and the current status of the prospectus included therein
or to file and maintain the effectiveness of another registration statement and another current prospectus covering the Warrants
and the Warrant Shares at any time that the Warrants are exercisable. The Company shall provide to the Warrant Agent and each Holder
prompt written notice of any time that the Company is unable to deliver the Warrant ADSs via DTC transfer or otherwise without
restrictive legend because (A) the Commission has issued a stop order with respect to the Registration Statement, (B) the Commission
otherwise has suspended or withdrawn the effectiveness of the Registration Statement, either temporarily or permanently, (C) the
Company has suspended or withdrawn the effectiveness of the Registration Statement, either temporarily or permanently, (D) the
prospectus contained in the Registration Statement is not available for the issuance of the Warrant ADSs to the Holder or (E) otherwise
(each a “Restrictive Legend Event”). To the extent that the Warrants cannot be exercised as a result of a Restrictive
Legend Event or a Restrictive Legend Event occurs after a Holder has exercised Warrants in accordance with the terms of the Warrants
but prior to the delivery of the Warrant ADSs, the Company shall, at the election of the Holder, which shall be given within five
(5) days of receipt of such notice of the Restrictive Legend Event, either (A) rescind the previously submitted Election to Purchase
and the Company shall return all consideration paid by registered holder for such shares upon such rescission or (B) treat the
attempted exercise as a cashless exercise as described in paragraph (ii) below and refund the cash portion of the exercise price
to the Holder.


 


(ii) If a Restrictive Legend Event has
occurred, the Warrant shall only be exercisable on a cashless basis. Notwithstanding anything herein to the contrary, the Company
shall not be required to make any cash payments or net cash settlement to the Holder in lieu of delivery of the Warrant ADSs. Upon
a “cashless exercise”, the Holder shall be entitled to receive the number of Warrant ADSs equal to the quotient obtained
by dividing (A-B) (X) by (A), where:


 


	 	(A)	= the VWAP on the Trading Day immediately preceding the Exercise Date;


 


	 	(B)	= the Exercise Price of the Warrant, as adjusted as set forth herein; and


 


	 	(X)	= the number of Warrant ADSs that would be issuable upon exercise of the Warrant in accordance with the terms of the Warrant if such exercise were by means of a cash exercise rather than a cashless exercise.


 


If the Warrant ADSs are issued in such
a cashless exercise, the Company acknowledges and agrees that, in accordance with Section 3(a)(9) of the Securities Act, the Warrant
ADSs shall take on the registered characteristics of the Warrants being exercised and the Company agrees not to take any position
contrary thereto. Upon receipt of an Election to Purchase for a cashless exercise, the Warrant Agent will promptly deliver a copy
of the Election to Purchase to the Company to confirm the number of Warrant ADSs issuable in connection with the cashless exercise.
The Company shall calculate and transmit to the Warrant Agent in a written notice, and the Warrant Agent shall have no duty, responsibility
or obligation under this section to calculate, the number of Warrant ADSs issuable in connection with any cashless exercise. The
Warrant Agent shall be entitled to rely conclusively on any such written notice provided by the Company, and the Warrant Agent
shall not be liable for any action taken, suffered or omitted to be taken by it in accordance with such written instructions or
pursuant to this Warrant Agreement.


 




     


     


    

  


A Holder that exercises Warrants in a cashless
exercise, as a condition of making that exercise, will still be required to pay the Issuance Fee in respect of the actual number
of Warrant ADSs that the Holder will receive.


 


3.3.8 Disputes. In the case of a
dispute as to the determination of the Exercise Price or the arithmetic calculation of the number of Warrant ADSs issuable in connection
with any exercise, the Company shall promptly deliver to the Holder the number of Warrant ADSs that are not disputed.


 


3.3.9 Compensation for Buy-In on
Failure to Timely Deliver Warrant ADSs Upon Exercise.  In addition to any other rights available to the Holder, if the
Company fails to cause the Depositary to deliver the Warrant ADSs to the Holder pursuant to Section 3.3.2 on or before 5:00 p.m.
(New York City time) on the second Trading Day after the Delivery Time, and if after such date the beneficial owner is required
by its broker to purchase (in an open market transaction or otherwise) or the beneficial owner’s brokerage firm otherwise
purchases, ADSs or Ordinary Shares to deliver in satisfaction of a sale by the beneficial owner of the Warrant ADSs, which the
beneficial owner anticipated receiving upon such exercise (a “Buy-In”), then the Company shall (A) pay in cash
to the Holder the amount, if any, by which (x) the beneficial owner’s total purchase price (including brokerage commissions,
if any) for the Warrant ADSs or Warrant Shares so purchased exceeds (y) the amount obtained by multiplying (1) the number of Warrant
ADSs or Warrant Shares, as applicable, that the Company was required to deliver to the Holder in connection with the exercise at
issue times (2) the price at which the sell order giving rise to such purchase obligation was executed, and (B) at the option of
the Holder, either reinstate the portion of the Warrant and equivalent number of Warrant ADSs or Warrant Shares, as applicable,
for which such exercise was not honored (in which case such exercise shall be deemed rescinded) or deliver to the Holder the number
of Warrant ADSs or Warrant Shares, as applicable, that would have been issued had the Company timely complied with its delivery
obligations.  For example, if the beneficial owner purchases Ordinary Shares having a total purchase price of $11,000 to cover
a Buy-In with respect to an attempted exercise of Warrant ADSs with an aggregate sale price giving rise to such purchase obligation
of $10,000, under clause (A) of the immediately preceding sentence, the Company shall be required to pay the Holder $1,000 for
the benefit of the beneficial owner. The Holder shall provide the Company written notice indicating the amounts payable to the
Holder in respect of the Buy-In and, upon request of the Company, evidence of the amount of such loss.  Nothing herein shall
limit right of a Holder to pursue any other remedies available to it hereunder, at law or in equity including, without limitation,
a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver Warrant
ADSs upon exercise of Warrants as required pursuant to the terms of this Warrant Agreement.


 




     


     


    

  


3.3.10Beneficial Ownership Limitation.
A Holder shall not have the right to exercise any Warrants to the extent that after giving effect to the issuance of Warrant ADSs
after exercise as set forth on the applicable Election to Purchase, such Holder or a person holding through such Holder (together
with such Holder’s or person’s Affiliates (as defined in Rule 405 under the Securities Act), and any other persons
acting as a group together with that Holder or person or any of that Holder’s or person’s Affiliates), would beneficially
own in excess of 4.99% (“Beneficial Ownership Limitation”) of the Company’s Ordinary Shares. For purposes
of the foregoing sentence, the number of Ordinary Shares beneficially owned by a person shall include the number of Ordinary Shares
underlying the Warrant ADSs that would be owned by that person issuable upon exercise of the Warrants with respect to which such
determination is being made, but shall exclude the number of Ordinary Shares (i) underlying the Warrant ADSs which would be issuable
upon exercise of the remaining, non-exercised Warrants beneficially owned by that person or any of its Affiliates and (ii) underlying
any other securities of the Company held by such Holder or its Affiliates that are exercisable or convertible into Ordinary Shares
and subject to a limitation on conversion or exercise that is analogous to the limitation contained in this Section 3.3.10. Except
as set forth in the preceding sentence, for purposes of this Section 3.3.10, beneficial ownership shall be calculated in accordance
with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and the rules and
regulations promulgated thereunder, it being acknowledged by the Holder that neither the Warrant Agent nor the Company is representing
to the Holder that such calculation is in compliance with Section 13(d) of the Exchange Act and the Holder or beneficial owner
is solely responsible for any schedules required to be filed in accordance therewith. To the extent that the limitation contained
in this Section 3.3.10 applies, the determination of whether a Warrant is exercisable and of the number of Warrants that are exercisable
shall be in the sole discretion of the Holder, and the submission of an Election to Purchase shall be deemed to be the Holder’s
determination of whether such Warrant is exercisable and of the number of Warrants that are exercisable, and neither the Warrant
Agent nor the Company shall have any obligation to verify or confirm the accuracy of such determination and neither of them shall
have any liability for any error made by the Holder or any other person. 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 this Section 3.3.10, in determining the number of outstanding Ordinary Shares, a Holder or other person
may rely on the number of outstanding Ordinary Shares as reflected in (A) the Company’s most recent periodic or annual report
filed with the Securities and Exchange Commission, as the case may be, (B) a more recent public announcement by the Company or
(C) a more recent written notice by the Company or the Company’s transfer agent setting forth the number of Ordinary Shares
outstanding. For any reason at any time, upon the written or oral request of a person that represents that it is or is acting on
behalf of a Holder, the Company shall, within two (2) Trading Days, confirm orally or in writing or by e-mail to that person the
number of Ordinary Shares then outstanding. Upon delivery of a written notice to the Company, the Holder may from time to time
increase or decrease the Beneficial Ownership Limitation to any other percentage not in excess of 9.99% as specified in such notice,
provided that any increase in the Beneficial Ownership Limitation will not be effective until the sixty-first (61st)
day after such notice is delivered to the Company and any such increase or decrease will apply only to the Holder and its Affiliates
and not to any other holder of Warrants. The provisions of this Section 3.3.10 shall be construed and implemented in a manner otherwise
than in strict conformity with the terms of this Section 3.3.10 to correct this subsection (or any portion hereof) which may be
defective or inconsistent with the intended beneficial ownership limitation herein contained.


 




     


     


    

  


4. Adjustments.


 


4.1 Adjustment upon Subdivisions or
Combinations. If the Company at any time after the Issuance Date subdivides (by any stock split, stock dividend, recapitalization,
reorganization, scheme of arrangement or otherwise) its outstanding Ordinary Shares into a greater number of Ordinary Shares or
the ratio of Ordinary Shares per ADS is reduced (e.g., the ratio is changed from 20 Ordinary Shares per one ADS to 10 Ordinary
Shares per one ADS), the Exercise Price in effect immediately prior to such subdivision will be proportionately reduced and the
number of Warrant ADSs will be proportionately increased. If the Company at any time after the Issuance Date combines (by any stock
split, stock dividend, recapitalization, reorganization, scheme, arrangement or otherwise) its outstanding Ordinary Shares into
a smaller number of Ordinary Shares or the ratio of Ordinary Shares per ADS is increased (e.g., the ratio is changed from 20 Ordinary
Shares per one ADS to 30 Ordinary Shares per one ADS), the Exercise Price in effect immediately prior to such combination will
be proportionately increased and the number of Warrant ADSs will be proportionately decreased. Any adjustment under this Section
4.1 shall become effective at the close of business on the date the subdivision or combination or ratio change becomes effective.
The Company shall promptly notify the Warrant Agent in writing of any adjustment to the Warrants and give specific instructions
to the Warrant Agent with respect to any adjustments to the warrant register.


 


4.2 Adjustment for Other Distributions.
In the event the Company shall fix a record date for the making of a dividend or distribution to all holders of Ordinary Shares
of any evidences of indebtedness or assets or subscription rights, options or warrants (excluding those referred to in Section
4.1 or other dividends paid out of retained earnings), then in each such case the Holder will, upon the exercise of Warrants, be
entitled to receive, in addition to the number of Warrant ADSs issuable thereupon, and without payment of any additional consideration
therefor, the amount of such dividend or distribution, as applicable, which such Holder would have held on the date of such exercise
had such Holder been the holder of record of such Warrant ADSs as of the date on which holders of ADSs became entitled to receive
such dividend or distribution. Such adjustment shall be made whenever any such distribution is made and shall become effective
immediately after the record date mentioned above.


 




     


     


    

  


4.3. Reclassification, Consolidation,
Purchase, Combination, Sale or Conveyance. 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,
(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
(including those represented by ADSs) 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 (including those represented by ADSs) (not
including any Ordinary Shares (including those represented by ADSs) held by the other person or other persons making or party to,
or associated or affiliated with the other persons making, such purchase offer, tender offer or exchange offer), (iv) the Company,
directly or indirectly, in one or more related transactions effects any reclassification, reorganization or recapitalization of
ADSs or Ordinary Shares or any compulsory share exchange pursuant to which the ADSs or Ordinary Shares are effectively converted
into or exchanged for other securities, cash or property, 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 whereby such other person acquires more than 50% of the
outstanding Ordinary Shares (including those represented by ADSs) (not including any Ordinary Shares (including those represented
by ADSs) 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 shall have the right to receive, for each Warrant 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 3.3.10 on the exercise of the Warrants), the number of shares, if any, of the successor or acquiring
corporation or of the Company, if it is the surviving corporation, or depositary shares representing those shares, and any additional
consideration (the “Alternate Consideration”) receivable as a result of such Fundamental Transaction by a holder
of the number of ADSs for which this Warrant is exercisable immediately prior to such Fundamental Transaction (without regard to
any limitation in Section 3.3.10 on the exercise of the Warrants). For purposes of any such exercise, the determination of the
Exercise Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration
issuable in respect of one ADS in such Fundamental Transaction and the Company shall apportion the Exercise Price among the Alternate
Consideration in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration.
If holders of ADSs are given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then
the Holder shall be given the same choice as to the Alternate Consideration it receives upon any exercise of this Warrant following
such Fundamental Transaction. 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 of the obligations of the Company under
this Warrant Agreement in accordance with the provisions of this Section 4.3 pursuant to written agreements in customary form and
shall, upon the written request of the Holder of Warrants, deliver to that Holder in exchange for those Warrants a security of
the Successor Entity evidenced by a written instrument substantially similar in form and substance to those Warrants that is exercisable
for a corresponding number of shares of capital stock of such Successor Entity (or its parent entity), if any, plus any Alternate
Consideration, receivable as a result of such Fundamental Transaction by a holder of the number of ADSs for which those Warrants
were exercisable immediately prior to such Fundamental Transaction, and with an exercise price which applies the exercise price
hereunder to such shares of capital stock, if any, plus any Alternate Consideration (but taking into account the relative value
of the ADSs or Ordinary Shares prior to such Fundamental Transaction and the value of such shares of capital stock plus Alternative
consideration after that Fundamental Transaction, for the purpose of protecting the economic value those Warrants had 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 Warrant Agreement and the 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 Warrant
Agreement and the Warrant with the same effect as if such Successor Entity had been named as the Company herein.


 


The Company shall instruct the Warrant
Agent in writing to mail by first class mail, postage prepaid, to each Holder, written notice of the execution of any such amendment,
supplement or agreement with the Successor Entity. Any supplemented or amended agreement entered into by the successor corporation
or transferee shall provide for adjustments, which shall be as nearly equivalent as may be practicable to the adjustments provided
for in this Section 4.3. The Warrant Agent shall have no duty, responsibility or obligation to determine the correctness of any
provisions contained in such agreement or such notice, including but not limited to any provisions relating either to the kind
or amount of securities or other property receivable upon exercise of warrants or with respect to the method employed and provided
therein for any adjustments, and shall be entitled to rely conclusively for all purposes upon the provisions contained in any such
agreement. The provisions of this Section 4.3 shall similarly apply to successive reclassifications, changes, consolidations, mergers,
sales and conveyances of the kind described above.


 




     


     


    

  


4.4. Adjustment Upon Issuance of ADSs
or Ordinary Shares. If and whenever on or after the Issuance Date and prior to _____, 20181
(the “Applicable Period”), the Company issues, sells or delivers, or in accordance with this Section 4 is deemed
to have issued, sold or delivered , any ADSs or Ordinary Shares (including the issuance, sale or delivery of ADSs or Ordinary Shares
owned or held by or for the account of the Company, but excluding any Excluded Securities issued or sold or deemed to have been
issued, sold or delivered) for a consideration per ADS less than a price equal to the Exercise Price, in the case of an ADS, or
less than a price equal to the Ordinary Share Equivalent Price, in the case of an Ordinary Share, in each case in effect immediately
prior to such issuance, sale or delivery or deemed issuance, sale or delivery (such Exercise Price or Ordinary Share Equivalent
Price, as the case may be, then in effect is referred to as the “Applicable Price”) (the foregoing a “Dilutive
Issuance”), then immediately after such Dilutive Issuance, the Exercise Price then in effect shall be reduced to the
New Issuance Price (as defined in Section 10).


  


For all purposes of the foregoing (including,
without limitation, determining the adjusted Exercise Price and consideration per share under this Section 4.4), the following
shall be applicable:


 


(i) Issuance of
Options. If the Company grants or sells any Options (other than Options that qualify as Excluded Securities) during the Applicable
Period and the lowest price per share for which one ADS or Ordinary Share is issuable upon the exercise of any such Option or upon
conversion, exercise or exchange of any Convertible Securities issuable upon exercise of any such Option is less than the Applicable
Price, then such ADS or Ordinary Share shall be deemed to be outstanding and to have been issued and sold or delivered by the Company
at the time of the granting or sale of such Option for the New Issuance Price. For purposes of this Section 4.4(i), the “lowest
price per share for which one ADS or Ordinary Share is issuable upon the exercise of any such Options or upon conversion, exercise
or exchange of any Convertible Securities issuable upon exercise of any such Option” shall be equal to (1) the sum of the
lowest amounts of consideration (if any) received or receivable by the Company with respect to any one ADS or Ordinary Share upon
the granting or sale of such Option, upon exercise of such Option and upon conversion, exercise or exchange of any Convertible
Security issuable upon exercise of such Option minus (2) the sum of all amounts paid or payable to the holder of such Option (or
any other person or entity) upon the granting or sale of such Option, upon exercise of such Option and upon conversion, exercise
or exchange of any Convertible Security issuable upon exercise of such Option plus the value of any other consideration received
or receivable by, or benefit conferred on, the holder of such Option (or any other person or entity). Except as contemplated below,
no further adjustment of the Exercise Price shall be made upon the actual issuance of such ADSs or Ordinary Shares or of such Convertible
Securities upon the exercise of such Options or upon the actual issuance of such ADSs or Ordinary Shares upon conversion, exercise
or exchange of such Convertible Securities.


 





 






1
18 months from the date of issuance.


 




     


     


    

  


(ii) Issuance of
Convertible Securities. If the Company issues or sells any Convertible Securities (other than Convertible Securities that qualify
as Excluded Securities) during the Applicable Period and the lowest price per share for which one ADS or Ordinary Share is issuable
upon the conversion, exercise or exchange thereof is less than the Applicable Price, then such ADS or Ordinary Share shall be deemed
to be outstanding and to have been issued and sold or delivered by the Company at the time of the issuance or sale of such Convertible
Securities for the New Issuance Price. For the purposes of this Section 4.4(ii), the “lowest price per share for which one
ADS or Ordinary Share is issuable upon the conversion, exercise or exchange thereof” shall be equal to (x) the sum of the
lowest amounts of consideration (if any) received or receivable by the Company with respect to one ADS or Ordinary Share upon the
issuance or sale of the Convertible Security and upon conversion, exercise or exchange of such Convertible Security minus (2) the
sum of all amounts paid or payable to the holder of such Convertible Security (or any other person or entity) upon the issuance
or sale of such Convertible Security plus the value of any other consideration received or receivable by, or benefit conferred
on, the holder of such Convertible Security (or any other person or entity). Except as contemplated below, no further adjustment
of the Exercise Price shall be made upon the actual issuance of such ADSs or Ordinary Shares upon conversion, exercise or exchange
of such Convertible Securities, and if any such issue or sale of such Convertible Securities is made upon exercise of any Options
for which adjustment of Warrants has been or is to be made pursuant to other provisions of this Section 4.4, except as contemplated
below, no further adjustment of the Exercise Price shall be made by reason of such issue, sale or delivery.


 


(iii) Change in Option Price. If
during the Applicable Period the purchase or exercise price provided for in any Options, the additional consideration, if any,
payable upon the issue, conversion, exercise or exchange of any Convertible Securities or the rate at which any Convertible Securities
are convertible into or exercisable or exchangeable for ADSs or Ordinary Shares increases or decreases at any time, the Exercise
Price in effect at the time of such increase or decrease shall be adjusted to the Exercise Price which would have been in effect
at such time had such revised terms been in effect. For purposes of this Section 4.4(iii), if the terms of any Option or Convertible
Security that was outstanding as of the original issuance of the Warrants are increased or decreased in the manner described in
the immediately preceding sentence, then such Option or Convertible Security and the ADSs or Ordinary Shares deemed issuable upon
exercise, conversion or exchange thereof shall be deemed to have been issued as of the date of such increase or decrease. No adjustment
pursuant to this Section 4.4 shall be made if such adjustment would result in an increase of the Exercise Price then in effect.
For purposes of clarity, if the Company enters into a Variable Rate Transaction (as defined in the Underwriting Agreement), despite
the prohibition thereon in the Underwriting Agreement, the Company shall be deemed to have issued Ordinary Shares, ADSs, Options
or Convertible Securities at the lowest possible conversion or exercise price at which such securities may be converted or exercised.
For purposes herein, no Variable Rate Transaction shall be Excluded Securities.


 


4.5 Other Events. If any event occurs
of the type contemplated by the provisions of Section 4.1, 4.2 or 4.4 but not expressly provided for by such provisions (including,
without limitation, the granting of stock appreciation rights, Adjustment Rights, phantom stock rights or other rights with equity
features to all holders of ADSs for no consideration), then the Company's Board of Directors will, at its discretion and in good
faith, make an adjustment in the Exercise Price and the number of Warrant ADSs or designate such additional consideration to be
deemed issuable upon exercise of a Warrant, so as to protect the rights of the registered Holder. No adjustment to the Exercise
Price will be made pursuant to more than one sub-section of this Section 4 in connection with a single issuance.


 




     


     


    

  


4.6. Notices of Changes in Warrant.
Upon every adjustment of the Exercise Price or the number of Warrant ADSs 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 Warrant ADSs 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 event specified in Sections 4.1 or 4.2, then, in any such event, the Company shall give written notice to each Holder, at the
last address set forth for such holder in the Warrant Register, as 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. The Warrant Agent shall be
entitled to rely conclusively on, and shall be fully protected in relying on, any certificate, notice or instructions provided
by the Company with respect to any adjustment of the Exercise Price or the number of shares issuable upon exercise of a Warrant,
or any related matter, and the Warrant Agent shall not be liable for any action taken, suffered or omitted to be taken by it in
accordance with any such certificate, notice or instructions or pursuant to this Warrant Agreement. The Warrant Agent shall not
be deemed to have knowledge of any such adjustment unless and until it shall have received written notice thereof from the Company.


 


5. Restrictive Legends; Fractional Warrants.


 


In the event that a Warrant Certificate
surrendered for transfer bears a restrictive legend, the Warrant Agent shall not register that transfer until the Warrant Agent
has received an opinion of counsel for the Company stating that such transfer may be made and indicating whether the Warrants must
also bear a restrictive legend upon that transfer. The Warrant Agent shall not be required to effect any registration of transfer
or exchange which will result in the transfer of or delivery of a Warrant Certificate for a fraction of a Warrant.


  


6. [RESERVED]


 


7. Other Provisions Relating to Rights
of Holders of Warrants.


 


7.1. No Rights as Stockholder. Except
as otherwise specifically provided herein, a Holder, solely in its capacity as a holder of Warrants, shall not be entitled to vote
or receive dividends or be deemed the holder of share capital of the Company for any purpose, nor shall anything contained in this
Warrant Agreement be construed to confer upon a Holder, solely in its capacity as the registered holder of Warrants, any of the
rights of a stockholder of the Company or any right to vote, give or withhold consent to any corporate action (whether any reorganization,
issue of stock, reclassification of share capital, consolidation, merger, conveyance or otherwise), receive notice of meetings,
receive dividends or subscription rights or rights to participate in new issues of shares, or otherwise, prior to the issuance
to the Holder of the Warrant ADSs which it is then entitled to receive upon the due exercise of Warrants.


 


7.2. 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.


 




     


     


    

  


8. Concerning the Warrant Agent and
Other Matters.


 


8.1. Any instructions given to the Warrant

to act, in accordance with any oral instructions which do not conform with the written confirmation received in accordance with
this Section 8.1.

for providing services to the Warrant Agent with respect to the Warrants and the expenses for which the Warrant Agent is obliged
to reimburse Computershare, and the fees and expenses of the Warrant Agent’s counsel. While the Warrant Agent endeavors to
maintain out-of-pocket charges (both internal and external) at competitive rates, these charges may not reflect actual out-of-pocket
costs, and may include handling charges to cover internal processing and use of the Warrant Agent’s billing systems.


 


(b) All amounts owed by the Company to
the Warrant Agent under this Warrant Agreement are due within 30 days of the invoice date. Delinquent payments are subject to a

of its duties under this Warrant Agreement or in the exercise of its rights.

the Warrant Agent:


 


(a) shall have no duties

(e) may rely on and
shall be fully authorized and protected in acting or failing to act upon any certificate, instrument, opinion, notice, letter,
telegram, telex, facsimile transmission or other document or security delivered to the Warrant Agent and believed by it to be genuine

(f) shall not be liable
or responsible for any recital or statement contained in the Registration Statement or any other documents relating thereto;

of its duties hereunder from the Company or counsel to the Company, and may apply to the Company, for advice or instructions in
connection with the Warrant Agent’s duties hereunder, and the Warrant Agent shall not be liable for any delay in acting while
waiting for those instructions; any applications by the Warrant Agent for written instructions from the Company may, at the option
of the Agent, set forth in writing any action proposed to be taken or omitted by the Warrant Agent under this Warrant Agreement
and the date on or after which such action shall be taken or such omission shall be effective; the Warrant Agent shall not be liable
for any action taken by, or omission of, the Warrant Agent in accordance with a proposal included in such application on or after
the date specified in such application (which date shall not be less than five business days after the date such application is
sent to the Company, unless the Company shall have consented in writing to any earlier date) unless prior to taking any such action,
the Warrant Agent shall have received written instructions in response to such application specifying the action to be taken or
omitted; “Business Day” means a day other than a Saturday or Sunday on which commercial Banks in New York City
are open for the general conduct of banking business;


 


(i) may consult with counsel satisfactory

protection in respect of any action taken, suffered, or omitted by it hereunder in good faith and in accordance with the advice
of such counsel;


 


(j) may perform any
of its duties hereunder either directly or by or through nominees, correspondents, designees, subagents or subcustodians, and it

and expenses of which shall be at the Company’s expense, to resolve any foreign law issues that may arise as a result of
the Company or any other party being subject to the laws or regulations of any foreign jurisdiction.


 




     


     


    

  


8.4. (a) In the absence of gross negligence
or willful misconduct on its part, the Warrant Agent shall not be liable for any action taken, suffered, or omitted by it or for
any error of judgment made by it in the performance of its duties under this Warrant Agreement. Anything in this Warrant Agreement
to the contrary notwithstanding, in no event shall Warrant Agent be liable for special, indirect, incidental, consequential or
punitive losses or damages of any kind whatsoever (including but not limited to lost profits), even if the Warrant Agent has been
advised of the possibility of such losses or damages and regardless of the form of action. Any liability of the Warrant Agent will
be limited in the aggregate to the amount of fees paid by the Company hereunder. The Warrant Agent shall not be liable for any
failures, delays or losses, arising directly or indirectly out of conditions beyond its reasonable control including, but not limited
to, acts of government, exchange or market ruling, suspension of trading, work stoppages or labor disputes, fires, civil disobedience,
riots, rebellions, storms, electrical or mechanical failure, computer hardware or software failure, communications facilities failures
including telephone failure, war, terrorism, insurrection, earthquakes, floods, acts of God or similar occurrences.


 


(b) In the event any
question or dispute arises with respect to the proper interpretation of the Warrants or the Warrant Agent’s duties under
this Warrant Agreement or the rights of the Company or of any Holder, the Warrant Agent shall not be required to act and shall
not be held liable or responsible for its refusal to act until the question or dispute has been judicially settled (and, if appropriate,
it may file a suit in interpleader or for a declaratory judgment for such purpose) by final judgment rendered by a court of competent
jurisdiction, binding on all persons interested in the matter which is no longer subject to review or appeal, or settled by a written
document in form and substance satisfactory to Warrant Agent and executed by the Company and each such Holder. In addition, the
Warrant Agent may require for such purpose, but shall not be obligated to require, the execution of such written settlement by
all the Holders and all other persons that may have an interest in the settlement.


 


8.5. The Company covenants to indemnify
the Warrant Agent and hold it harmless from and against any loss, liability, claim or expense (“Loss”) arising
out of or in connection with the Warrant Agent’s duties under this Warrant Agreement, including the costs and expenses of
defending itself against any Loss, unless such Loss shall have been determined by a court of competent jurisdiction to be a result
of the Warrant Agent’s gross negligence or willful misconduct.


 


8.6. Unless terminated earlier by the parties
hereto, this Agreement shall terminate 90 days after the earlier of the Expiration Date and the date on which no Warrants remain
outstanding (the “Termination Date”). On the business day following the Termination Date, the Agent shall deliver
to the Company any entitlements, if any, held by the Warrant Agent under this Warrant Agreement. The Agent’s right to be
indemnified and held harmless and to be reimbursed for fees, charges and out-of-pocket expenses as provided in this Section 8 shall
survive the termination of this Warrant Agreement.


 


8.7. If any provision of this Warrant Agreement
shall be held illegal, invalid, or unenforceable by any court, this Warrant Agreement shall be construed and enforced as if such
provision had not been contained herein and shall be deemed an Agreement among the parties to it to the full extent permitted by
applicable law.


 




     


     


    

  


8.8. The Company represents and warrants

a party or is bound, (c) this Warrant Agreement has been duly executed and delivered by the Company and constitutes the legal,
valid, binding and enforceable obligation of the Company, (d) the Warrants will comply in all material respects with all applicable

connection with the offering of the Warrants.

be governed by and construed in accordance with the laws of the State of New York. All actions and proceedings relating to or arising

not be assigned, or otherwise transferred, in whole or in part, by either party without the prior written consent of the other
party, which the other party will not unreasonably withhold, condition or delay; except that (i) consent is not required for an
assignment or delegation of duties by Warrant Agent to any affiliate of Warrant Agent and (ii) any reorganization, merger, consolidation,
sale of assets or other form of business combination by Warrant Agent or the Company shall not be deemed to constitute an assignment
of this Warrant Agreement.


 




     


     


    

  


(c) No provision of
this Warrant Agreement may be amended, modified or waived, except in a written document signed by both parties. The Company and
the Warrant Agent may amend or supplement this Warrant Agreement without the consent of any Holder for the purpose of curing any
ambiguity, or curing, correcting or supplementing any defective provision contained herein or adding or changing any other provisions
with respect to matters or questions arising under this Agreement as the parties may deem necessary or desirable and that the parties
determine, in good faith, shall not adversely affect the interest of the Holders.  All other amendments and supplements
shall require the vote or written consent of Holders of at least 50.1% of the then outstanding Warrants, provided that adjustments
may be made to the Warrant terms and rights in accordance with Section 4 without the consent of the Holders.


 


8.13 Payment of Taxes. The Company
will from time to time promptly pay all taxes and charges that may be imposed upon the Company or the Warrant Agent in respect
of the issuance or delivery of Warrant Shares or Warrant ADSs upon the exercise of Warrants, but the Company may require the Holders
to pay any transfer taxes in respect of the Warrants or such shares. The Warrant Agent may refrain from registering any transfer
of Warrants or any delivery of any Warrant ADSs unless or until the persons requesting the registration or issuance shall have
paid to the Warrant Agent for the account of the Company the amount of such tax or charge, if any, or shall have established to
the reasonable satisfaction of the Company and the Warrant Agent that such tax or charge, if any, has been paid.


 


8.14 Resignation of Warrant Agent.


 


8.14.1. 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 thirty (30) days’ notice in writing to the Company, or such shorter period
of time agreed to by the Company. The Company may terminate the services of the Warrant Agent, or any successor Warrant Agent,
after giving thirty (30) days’ notice in writing to the Warrant Agent or successor Warrant Agent, or such shorter period
of time as agreed. If the office of the Warrant Agent becomes vacant by resignation, termination 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 30 days after it has been notified in writing of such resignation or incapacity by the Warrant
Agent, then the Warrant Agent or any Holder may apply to any court of competent jurisdiction for the appointment of a successor
Warrant Agent at the Company’s cost. Pending appointment of a successor to such Warrant Agent, either by the Company or by

		(e)	“C” shall mean the number of such additional ADSs or Ordinary Shares issued in such
transaction.
