Number of American Depositary Shares: ________________


 


THIS WARRANT TO PURCHASE
ORDINARY SHARES REPRESENTED BY AMERICAN DEPOSITARY SHARES (the “Warrant”) certifies that, for value received,
_____________ or its assigns (the “Holder”) is entitled, upon the terms and subject to the limitations on exercise
and the conditions hereinafter set forth, at any time on or after September 11, 2017 (the “Initial Exercise Date”)
and on or prior to the close of business on the one-year anniversary of the Initial Exercise Date (the “Termination Date”)
but not thereafter, to subscribe for and purchase from Cellect Biotechnology Ltd., an Israeli limited company (the “Company”),
up to ______ Ordinary Shares (the “Warrant Shares”) represented by ________ American Depositary Shares (“ADSs”),
as subject to adjustment hereunder (the “Warrant ADSs”). The purchase price of one Warrant ADS shall be equal
to the Exercise Price, as defined in Section 2(b). This Warrant is issued pursuant to that certain Engagement Agreement, dated
September 6, 2017, between the Company and H.C. Wainwright & Co., LLC.


 


Section 1.Definitions.
Capitalized terms used and not otherwise defined herein shall have the meanings set forth in that certain Securities Purchase Agreement
(the “Purchase Agreement”), dated September 7, 2017, 2017, among the Company and the purchasers signatory thereto.


 






    	 	1	 



     


    




 


Section 2.Exercise.


 


a) Exercise
of Warrant. Exercise of the purchase rights represented by this Warrant may be made, in whole or in part, at any time or times
on or after the Initial Exercise Date and on or before the Termination Date by delivery to the Company (or such other office or
agency of the Company as it may designate by notice in writing to the registered Holder at the address of the Holder appearing
on the books of the Company) and the Depositary of a duly executed facsimile copy (or .pdf copy via e-mail) of the Notice
of Exercise in the form annexed hereto. Within the earlier of (i) three (3) Trading Days and (ii) the number of Trading Days comprising
the Standard Settlement Period (as defined in Section 2(d)(i) herein) following the date of exercise as aforesaid the Holder shall
deliver the aggregate Exercise Price of the Warrant ADSs thereby purchased by wire transfer or cashier’s check drawn on a
United States bank or, if available, pursuant to the cashless exercise procedure specified in Section 2(c) below. No ink-original
Notice of Exercise shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice
of Exercise form be required. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender
this Warrant to the Company until the Holder has purchased all of the Warrant ADSs available hereunder and the Warrant has been
exercised in full, in which case, the Holder shall surrender this Warrant to the Company for cancellation within three (3) Trading
Days of the date the final Notice of Exercise is delivered to the Company. Partial exercises of this Warrant resulting in purchases
of a portion of the total number of Warrant ADSs available hereunder shall have the effect of lowering the outstanding number of
Warrant ADSs purchasable hereunder in an amount equal to the applicable number of Warrant ADSs purchased. The Holder and the Company
shall maintain records showing the number of Warrant ADSs purchased and the date of such purchases. The Company shall deliver any
objection to any Notice of Exercise within one (1) Business Day of receipt of such notice. The Holder and any assignee, by acceptance
of this Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following the purchase of a portion
of the Warrant ADSs hereunder, the number of Warrant ADSs available for purchase hereunder at any given time may be less than the
amount stated on the face hereof.


 


b) Exercise
Price. The exercise price per ADS under this Warrant shall be $10.125, subject to adjustment hereunder (the “Exercise
Price”).


 


c) Cashless
Exercise. If at any time after the Initial Exercise Date there is no effective Registration Statement registering, or no current
prospectus available for, the resale of the Warrant ADSs by the Holder, then this Warrant may also be exercised, in whole or in
part, at such time by means of a “cashless exercise” in which the Holder shall be entitled to receive a number of Warrant
ADSs equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:


 


	 	(A)  =	the last VWAP immediately preceding the time of delivery of the Notice of Exercise giving rise to the applicable “cashless exercise”, as set forth in the applicable Notice of Exercise (to clarify, the “last VWAP” will be the last VWAP as calculated over an entire Trading Day such that, in the event that this Warrant is exercised at a time that the Trading Market is open, the prior Trading Day’s VWAP shall be used in this calculation);
	 	 	 
	 	(B)  =	the Exercise Price of this Warrant, as adjusted hereunder; and
	 	 	 
	 	(X)  =	the number of Warrant ADSs that would be issuable upon exercise of this Warrant in accordance with the terms of this Warrant if such exercise were by means of a cash exercise rather than a cashless exercise.


 



    	 	2	 



     


    

 


If
Warrant ADSs are issued in such a cashless exercise, the parties acknowledge and agree
that in accordance with Section 3(a)(9) of the Securities Act, the Warrant ADSs shall
take on the characteristics of the Warrants being exercised, and the holding period of the Warrants being exercised may be tacked
on to the holding period of the Warrant ADSs. The Company agrees not to take any position
contrary to this Section 2(c).


 


		d)	Mechanics of Exercise.



 


		i.	Delivery of Warrant ADSs Upon Exercise. Within 1 Trading day of the date that a Notice of
Exercise is delivered to the Company, the Company shall deposit the Warrant Shares subject to such exercise with The Bank of New
York Mellon, the Depositary for the ADSs (the “Depositary”) and instruct the Depositary to credit the account
of the Holder’s prime broker with The Depository Trust Company through its Deposit/Withdrawal At Custodian system (“DWAC”)
if the Depositary is then a participant in such system and either (A) there is an effective registration statement registering
for resale of the Warrant Shares represented by the Warrant ADSs by the Holder or (B) the Warrant Shares represented by the Warrant
ADSs are eligible for resale by the Holder without volume or manner-of-sale limitations pursuant to Rule 144 and the Warrant ADSs
have been sold by the Holder prior to the Warrant ADS Delivery Date (as defined below), and otherwise by physical delivery to the
address specified by the Holder in the Notice of Exercise, by the date that is the earlier of (i) three (3) Trading Days and (ii)
the number of Trading Days comprising the Standard Settlement Period after the delivery to the Company of the Notice of Exercise
(such date, the “Warrant ADS Delivery Date”). If the Warrant ADSs can be delivered via DWAC, then in addition
to the delivery of the Warrant Shares to the Depositary, within 2 Trading Days of the applicable exercise, the Depositary shall
have received from the Company any legal opinions or other documentation required by the Depositary to deliver such ADSs without
legend and, if applicable and requested by the Company prior to the Warrant ADS Delivery Date, the Depositary shall have received
from the Holder a confirmation of sale of the Warrant ADSs (provided the requirement of the Holder to provide a confirmation as
to the sale of Warrant ADSs shall not be applicable to the issuance of unlegended Warrant ADS’s upon a cashless exercise
of this Warrant if the Warrant ADSs are then eligible for resale pursuant to Rule 144(b)(1)). The Warrant Shares represented by
the Warrant ADSs shall be deemed to have been issued, and Holder or any other person so designated to be named therein shall be
deemed to have become the beneficial owner of such Warrant Shares represented by the Warrant ADSs for all purposes, as of the date
the Warrant has been exercised, with payment to the Company of the Exercise Price (or by cashless exercise, if permitted) and all
taxes required to be paid by the Holder, if any, pursuant to Section 2(d)(vi) prior to the issuance of such Warrant ADSs having
been paid. As used herein, “Standard Settlement Period” means the standard settlement period, expressed in a
number of Trading Days, on the Company’s primary Trading Market with respect to the Common Stock as in effect on the date
of delivery of the Notice of Exercise.



 






    	 	3	 



     


    




 


ii. Delivery
of New Warrants Upon Exercise. If this Warrant shall have been exercised in part, the Company shall, at the request of a Holder
and upon surrender of this Warrant certificate, at the time of delivery of the Warrant ADSs, deliver to the Holder a new Warrant
evidencing the rights of the Holder to purchase the unpurchased Warrant ADSs called for by this Warrant, which new Warrant shall
in all other respects be identical with this Warrant.


 


iii. Rescission
Rights. If the Company fails to cause the Transfer Agent to transmit to the Holder the Warrant ADSs pursuant to Section 2(d)(i)
by the Warrant ADS Delivery Date, then the Holder will have the right to rescind such exercise; provided, however,
that the Holder shall be required to return any Warrant ADSs or Warrant Shares subject to any such rescinded exercise notice concurrently
with the return to Holder of the aggregate Exercise Price paid to the Company for such Warrant ADSs and the restoration of Holder’s
right to acquire such Warrant ADSs pursuant to this Warrant (including, issuance of a replacement warrant certificate evidencing
such restored right).


 


iv. 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 to the Holder the Warrant ADSs in accordance with the provisions of Section
2(d)(i) above pursuant to an exercise on or before the Warrant ADS Delivery Date, and if after such date the Holder is required
by its broker to purchase (in an open market transaction or otherwise) or the Holder’s brokerage firm otherwise purchases,
ADSs to deliver in satisfaction of a sale by the Holder of the Warrant ADSs which the Holder 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 Holder’s
total purchase price (including brokerage commissions, if any) for the ADSs so purchased exceeds (y) the amount obtained by multiplying
(1) the number of Warrant ADSs 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 for which such exercise was not honored
(in which case such exercise shall be deemed rescinded) or deliver to the Holder the number of ADSs that would have been issued
had the Company timely complied with its exercise and delivery obligations hereunder. For example, if the Holder purchases ADSs
having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted exercise of 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. 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
a Holder’s right 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 ADSs upon
exercise of the Warrant as required pursuant to the terms hereof.


 






    	 	4	 



     


    




 


v. No
Fractional Shares or Scrip. No fractional Warrant Shares or Warrant ADSs shall be issued upon the exercise of this Warrant.
As to any fraction of an ADS which the Holder would otherwise be entitled to purchase upon such exercise, the Company shall, at
its election, either pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by
the Exercise Price or round up to the next whole ADS.


 


vi. Charges,
Taxes and Expenses. Issuance of Warrant ADSs shall be made without charge to the Holder for any issue or transfer tax or other
incidental expense in respect of the issuance of Warrant ADSs, all of which taxes and expenses shall be paid by the Company, and
such Warrant ADSs shall be issued in the name of the Holder or in such name or names as may be directed by the Holder; provided,
however, that in the event that Warrant ADSs are to be issued in a name other than the name of the Holder, this Warrant
when surrendered for exercise shall be accompanied by the Assignment Form attached hereto duly executed by the Holder and the Company
may require, as a condition thereto, the payment of a sum sufficient to reimburse it for any transfer tax incidental thereto. The
Company shall pay all Depositary fees required for same-day processing of any Notice of Exercise and all fees to the Depository
Trust Company (or another established clearing corporation performing similar functions) required for same-day electronic delivery
of the Warrant Shares.


 


vii. Closing
of Books. The Company will not close its shareholder books or records in any manner which prevents the timely exercise of this
Warrant, pursuant to the terms hereof.

e) Holder’s
Exercise Limitations. Notwithstanding anything to the contrary contained herein, the Company shall not effect the exercise
of any portion of this Warrant, and the Holder shall not have the right to exercise any portion of this Warrant, pursuant to the
terms and conditions of this Warrant and any such exercise shall be null and void and treated if never made, to the extent that
after giving effect to such exercise, the Holder together with the other Attribution Parties collectively would beneficially own
in excess of 4.99% (the “Maximum Percentage”) of the number of Ordinary Shares outstanding immediately after
giving effect to such exercise. For purposes of the foregoing sentence, the aggregate number of Ordinary Shares beneficially owned
by the Holder and the other Attribution Parties shall include the number of Ordinary Shares underlying ADSs held by the Holder
and all other Attribution Parties plus the number of Ordinary Shares underlying ADSs issuable upon exercise of this Warrant with
respect to which the determination of such sentence is being made, but shall exclude the number of Ordinary Shares underlying ADSs
which would be issuable upon (A) exercise of the remaining, unexercised portion of this Warrant beneficially owned by the Holder
or any of the other Attribution Parties and (B) exercise or conversion of the unexercised or unconverted portion of any other securities
of the Company beneficially owned by the Holder or any other Attribution Party subject to a limitation on conversion or exercise
analogous to the limitation contained in this Section 2(e). For purposes of this Section 2(e), beneficial ownership shall be calculated
in accordance with Section 13(d) of the Exchange Act. For purposes of this Warrant, in determining the number of Ordinary Shares
underlying ADSs the Holder may acquire upon the exercise of this Warrant without exceeding the Maximum Percentage, the Holder may
rely on the number of Ordinary Shares as reflected in (x) the Company's most recent Annual Report on Form 20-F, Current Report
on Form 6-K or other public filing with the Commission, as the case may be, (y) a more recent public announcement by the Company
or (3) any other written notice by the Company setting forth the number of Ordinary Shares outstanding (the “Reported
Outstanding Share Number”). If the Company receives an Exercise Notice from the Holder at a time when the actual number
of outstanding Ordinary Shares is less than the Reported Outstanding Share Number, the Company shall (i) notify the Holder in writing
of the number of Ordinary Shares then outstanding and, to the extent that such Exercise Notice would otherwise cause the Holder's
beneficial ownership, as determined pursuant to this Section 2(e), to exceed the Maximum Percentage, the Holder must notify the
Company of a reduced number of Warrant ADSs to be purchased pursuant to such Exercise Notice (the number of shares by which such
purchase is reduced, the “Reduction Shares”) and (ii) as soon as reasonably practicable, the Company shall return
to the Holder any exercise price paid by the Holder for the Reduction Shares. For any reason at any time, upon the written or oral
request of the Holder, the Company shall within one (1) Business Day confirm orally and in writing or by electronic mail to the
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 this Warrant, by the Holder and any other
Attribution Party since the date as of which the Reported Outstanding Share Number was reported. In the event that the issuance
of Ordinary Shares to the Holder upon exercise of this Warrant results in the Holder and the other Attribution Parties being deemed
to beneficially own, in the aggregate, more than the Maximum Percentage of the number of outstanding Ordinary Shares (as determined
under Section 13(d) of the Exchange Act), the number of shares so issued by which the Holder's and the other Attribution Parties'
aggregate beneficial ownership exceeds the Maximum Percentage (the “Excess Shares”) shall be deemed null and
void and shall be cancelled ab initio, and the Holder shall not have the power to vote or to transfer the Excess Shares. As soon
as reasonably practicable after the issuance of the Excess Shares has been deemed null and void, the Company shall return to the
Holder the exercise price paid by the Holder for the Excess Shares. Upon delivery of a written notice to the Company, the Holder
may from time to time increase (with such increase not effective until the sixty-first (61st) day after delivery of
such notice) or decrease the Maximum Percentage to any other percentage not in excess of 9.99% as specified in such notice; provided
that (i) any such increase in the Maximum Percentage 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 the Holder and the other Attribution
Parties and not to any other holder of Warrants that is not an Attribution Party of the Holder. For purposes of clarity, the Ordinary
Shares issuable pursuant to the terms of this Warrant in excess of the Maximum Percentage shall not be deemed to be beneficially
owned by the 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
2(e) to the extent necessary to correct this paragraph or any portion of this paragraph which may be defective or inconsistent
with the intended beneficial ownership limitation contained in this Section 2(e) or to make changes or supplements necessary or
desirable to properly give effect to such limitation. The limitation contained in this paragraph may not be waived and shall apply
to a successor holder of this Warrant. “Attribution Parties” means, collectively, the following Persons and
entities: (i) any investment vehicle, including, any funds, feeder funds or managed accounts, currently, or from time to time after
the issuance date, directly or indirectly managed or advised by the Holder's investment manager or any of its Affiliates or principals,
(ii) any direct or indirect Affiliates of the Holder or any of the foregoing, (iii) any Person acting or who could be deemed to
be acting as a group together with the Holder or any of the foregoing and (iv) any other Persons whose beneficial ownership of
the Company's Ordinary Shares would or could be aggregated with the Holder's and the other Attribution Parties for purposes of
Section 13(d) of the Exchange Act. For clarity, the purpose of the foregoing is to subject collectively the Holder and all other
Attribution Parties to the Maximum Percentage.

Section 3.Certain
Adjustments.


 


a) Share
Dividends and Splits. If the Company, at any time while this Warrant is outstanding: (i) pays a share dividend or otherwise
makes a distribution or distributions on its Ordinary Shares or ADSs or any other equity or equity equivalent securities payable
in Ordinary Shares or ADSs (which, for avoidance of doubt, shall not include any ADSs issued by the Company upon exercise of this
Warrant), as applicable, (ii) subdivides outstanding Ordinary Shares or ADSs into a larger number of shares or ADSs, as applicable,
(iii) combines (including by way of reverse share split) outstanding Ordinary Shares or ADSs into a smaller number of shares or
ADSs, as applicable, or (iv) issues by reclassification of Ordinary Shares, ADSs or any shares of capital stock of the Company,
as applicable, then in each case the Exercise Price shall be multiplied by a fraction of which the numerator shall be the number
of ADSs (excluding treasury shares, if any) outstanding immediately before such event and of which the denominator shall be the
number of ADSs outstanding immediately after such event, and the number of shares issuable upon exercise of this Warrant shall
be proportionately adjusted such that the aggregate Exercise Price of this Warrant shall remain unchanged. Any adjustment made
pursuant to this Section 3(a) shall become effective immediately after the record date for the determination of shareholders entitled
to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision,
combination or re-classification.


 


b) [RESERVED]


 


c) Subsequent
Rights Offerings. In addition to any adjustments pursuant to Section 3(a) above, if at any time the Company grants, issues
or sells any Ordinary Share Equivalents or rights to purchase shares, warrants, securities or other property pro rata to the record
holders of any class of Ordinary Shares or ADSs (the “Purchase Rights”), then the Holder will be entitled to
acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired
if the Holder had held the number of Ordinary Shares or ADSs acquirable upon complete exercise of this Warrant (without regard
to any limitations on exercise hereof, including without limitation, the Maximum Percentage) 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 or ADSs are to be determined for the grant, issue or sale of such Purchase Rights (provided,
however, to the extent that the Holder’s right to participate in any such Purchase Right would result in the Holder exceeding
the Maximum Percentage, then the Holder shall not be entitled to participate in such Purchase Right to such extent (or beneficial
ownership of such ADSs as a result of such Purchase Right to such extent) and such Purchase Right to such extent shall be held
in abeyance for the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Maximum
Percentage).


 






    	 	7	 



     


    




 


d) Pro
Rata Distributions. During such time as this Warrant is outstanding, if the Company shall declare or make any dividend (other
than cash) or other distribution of its assets (or rights to acquire its assets) to holders of Ordinary Shares or ADSs, by way
of return of capital or otherwise (including, without limitation, any distribution ofshares or other securities, property or options
by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction)
(a “Distribution”), at any time after the issuance of this Warrant, then, in each such case, the Holder shall
be entitled to participate in such Distribution to the same extent that the Holder would have participated therein if the Holder
had held the number of Ordinary Shares or ADSs acquirable upon complete exercise of this Warrant (without regard to any limitations
on exercise hereof, including without limitation, the Maximum Percentage) immediately before the date of 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 or ADSs are to
be determined for the participation in such Distribution (provided, however, to the extent that the Holder's right
to participate in any such Distribution would result in the Holder exceeding the Maximum Percentage, then the Holder shall not
be entitled to participate in such Distribution to such extent (or in the beneficial ownership of any Ordinary Shares or ADSs as
a result of such Distribution to such extent) and the portion of such Distribution shall be held in abeyance for the benefit of
the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Maximum Percentage).


 





e) Fundamental
Transactions. The Company shall not enter into or be party to a Fundamental Transaction (as defined below) unless the Successor
Entity (as defined below) assumes in writing all of the obligations of the Company under this Warrant and the other Transaction
Documents in accordance with the provisions of this Section 3(e) pursuant to written agreements, including agreements, if so requested
by the Holder, to deliver to each holder of the Warrants in exchange for such Warrants a security of the Successor Entity evidenced
by a written instrument substantially similar in form and substance to this Warrant, including, without limitation, an adjusted
exercise price equal to the value for the Ordinary Shares reflected by the terms of such Fundamental Transaction, and exercisable
for a corresponding number of shares of capital stock equivalent to the Ordinary Shares represented by ADSs acquirable and receivable
upon exercise of this Warrant (without regard to any limitations on the exercise of this Warrant) 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 adjustments to the number of shares of capital stock and such exercise price being for the purpose of protecting the economic
value of this Warrant immediately prior to the consummation of such Fundamental Transaction). Any security issuable or potentially
issuable to the Holder pursuant to the terms of this Warrant on the consummation of a Fundamental Transaction shall be registered
and freely tradable by the Holder without any restriction or limitation or the requirement to be subject to any holding period
pursuant to any applicable securities laws if any securities issued to any other equityholder of the Company are registered on
Form F-4 or any successor form. Upon the occurrence or consummation of any Fundamental Transaction, and it shall be a required
condition to the occurrence or consummation of any Fundamental Transaction that, the Company and the Successor Entity or Successor
Entities, jointly and severally, shall succeed to, and the Company shall cause any Successor Entity or Successor Entities to jointly
and severally succeed to, and be added to the term “Company” under this Warrant (so that from and after the date of
such Fundamental Transaction, each and every provision of this Warrant referring to the “Company” shall refer instead
to each of the Company and the Successor Entity or Successor Entities, jointly and severally), and the Company and the Successor
Entity or Successor Entities, jointly and severally, may exercise every right and power of the Company prior thereto and shall
assume all of the obligations of the Company prior thereto under this Warrant with the same effect as if the Company and such Successor
Entity or Successor Entities, jointly and severally, had been named as the Company in this Warrant, and, solely at the request
of the Holder, if the Successor Entity and/or Successor Entities is a publicly traded corporation whose common stock is quoted
on or listed for trading on a Trading Market in the United States, shall deliver (in addition to and without limiting any right
under this Warrant) to the Holder in exchange for this Warrant a security of the Successor Entity and/or Successor Entities evidenced
by a written instrument substantially similar in form and substance to this Warrant and exercisable for a corresponding number
of shares of capital stock of the Successor Entity and/or Successor Entities (the “Successor Capital Stock”)
equivalent to the Ordinary Shares underlying the ADSs acquirable and receivable upon exercise of this Warrant (without regard to
any limitations on the exercise of this Warrant) prior to such Fundamental Transaction (such corresponding number of shares of
Successor Capital Stock to be delivered to the Holder shall be equal to the quotient of (i) the aggregate dollar value of all consideration
(including cash consideration and any consideration other than cash (“Non-Cash Consideration”), in such Fundamental
Transaction, as such values are set forth in any definitive agreement for the Fundamental Transaction that has been executed at
the time of the first public announcement of the Fundamental Transaction or, if no such value is determinable from such definitive
agreement, as determined in accordance with Section 5(a) with the term "Non-Cash Consideration" being substituted for
the term "Exercise Price") that the Holder would have been entitled to receive upon the happening of such Fundamental
Transaction or the record, eligibility or other determination date for the event resulting in such Fundamental Transaction, had
this Warrant been exercised immediately prior to such Fundamental Transaction or the record, eligibility or other determination
date for the event resulting in such Fundamental Transaction (without regard to any limitations on the exercise of this Warrant)
divided by (ii) the per share closing sale price of such corresponding capital stock on the Trading Day immediately prior to the
consummation or occurrence of the Fundamental Transaction), and with an identical exercise price to the Exercise Price hereunder
(such adjustments to the number of shares of capital stock and such exercise price being for the purpose of protecting after the
consummation or occurrence of such Fundamental Transaction the economic value of this Warrant that was in effect immediately prior
to the consummation or occurrence of such Fundamental Transaction, as elected by the Holder solely at its option). Upon occurrence
or consummation of the Fundamental Transaction, and it shall be a required condition to the occurrence or consummation of such
Fundamental Transaction that, the Company and the Successor Entity or Successor Entities shall deliver to the Holder confirmation
that there shall be issued upon exercise of this Warrant at any time after the occurrence or consummation of the Fundamental Transaction,
as elected by the Holder solely at its option, ADSs, Successor Capital Stock or, in lieu of the ADSs or Successor Capital Stock
(or other securities, cash, assets or other property purchasable upon the exercise of this Warrant prior to such Fundamental Transaction),
such shares of stock, securities, cash, assets or any other property whatsoever (including warrants or other purchase or subscription
rights), which for purposes of clarification may continue to be ADSs, if any, that the Holder would have been entitled to receive
upon the happening of such Fundamental Transaction or the record, eligibility or other determination date for the event resulting
in such Fundamental Transaction, had this Warrant been exercised immediately prior to such Fundamental Transaction or the record,
eligibility or other determination date for the event resulting in such Fundamental Transaction (without regard to any limitations
on the exercise of this Warrant), as adjusted in accordance with the provisions of this Warrant.


 



    	 	8	 



     


    

 


In addition to and not in substitution
for any other rights hereunder, prior to the occurrence or consummation of any Fundamental Transaction pursuant to which holders
Ordinary Shares or ADSs are entitled to receive securities, cash, assets or other property with respect to or in exchange for Ordinary
Shares or ADSs (a “Corporate Event”), the Company shall make appropriate provision to insure that, and any applicable
Successor Entity or Successor Entities shall ensure that, and it shall be a required condition to the occurrence or consummation
of such Corporate Event that, the Holder will thereafter have the right to receive upon exercise of this Warrant at any time after
the occurrence or consummation of the Corporate Event, ADSs or Successor Capital Stock or, if so elected by the Holder, in lieu
of ADSs (or other securities, cash, assets or other property) purchasable upon the exercise of this Warrant prior to such Corporate
Event (but not in lieu of such items still issuable under Sections 3(c) and 3(d), which shall continue to be receivable on the
ADSs or on the such shares of stock, securities, cash, assets or any other property otherwise receivable with respect to or in
exchange for ADSs), such shares of stock, securities, cash, assets or any other property whatsoever (including warrants or other
purchase or subscription rights and any Ordinary Shares) which the Holder would have been entitled to receive upon the occurrence
or consummation of such Corporate Event or the record, eligibility or other determination date for the event resulting in such
Corporate Event, had this Warrant been exercised immediately prior to such Corporate Event or the record, eligibility or other
determination date for the event resulting in such Corporate Event (without regard to any limitations on exercise of this Warrant).
The provisions of this Section 3(e) shall apply similarly and equally to successive Fundamental Transactions and Corporate Events.
“Fundamental Transaction” means (A) that the Company shall, directly or indirectly, including through subsidiaries,
Affiliates or otherwise, in one or more related transactions, (i) consolidate or merge with or into (whether or not the Company
is the surviving corporation) another Person, or (ii) sell, assign, transfer, convey or otherwise dispose of all or substantially
all of the properties or assets of the Company or any of its "significant subsidiaries" (as defined in Rule 1-02 of Regulation
S-X) to one or more Persons, or (iii) make, or allow one or more Persons to make, or allow the Company to be subject to or have
its Ordinary Shares be subject to or party to one or more persons making, a purchase, tender or exchange offer that is accepted
by the holders of at least either (x) 50% of the outstanding Ordinary Shares, (y) 50% of the outstanding Ordinary Shares calculated
as if any Ordinary Shares held by all Persons making or party to, or Affiliated with any Persons making or party to, such purchase,

or Affiliated with any Person making or party to, such purchase, tender or exchange offer, become collectively the beneficial owners
(as defined in Rule 13d-3 under the Exchange Act) of at least 50% of the outstanding Ordinary Shares, or (iv) consummate a securities
purchase agreement or other business combination (including, without limitation, a reorganization, recapitalization, spin-off or
scheme of arrangement) with one or more Persons whereby all such Persons, individually or in the aggregate, acquire, either (x)
at least 50% of the outstanding Ordinary Shares, (y) at least 50% of the outstanding Ordinary Shares calculated as if any Ordinary
Shares held by all the Persons making or party to, or Affiliated with any Person making or party to, such securities purchase agreement

under Israeli law, (B) that the Company shall, directly or indirectly, including through subsidiaries, Affiliates or otherwise,
in one or more related transactions, allow any Person individually or the Persons in the aggregate to be or become the "beneficial

conveyance, tender, tender offer, exchange, reduction in outstanding Ordinary Shares, merger, consolidation, business combination,
reorganization, recapitalization, spin-off, scheme of arrangement, reorganization, recapitalization or reclassification or otherwise
in any manner whatsoever, of either (x) at least 50% of the aggregate ordinary voting power represented by issued and outstanding

issuance of or the entering into any other instrument or transaction structured in a manner to circumvent, or that circumvents,
the intent of this definition in which case this definition shall be construed and implemented in a manner otherwise than in strict
conformity with the terms of this definition to the extent necessary to correct this definition or any portion of this definition
which may be defective or inconsistent with the intended treatment of such instrument or transaction. Notwithstanding anything
contained herein, any transaction which results in a Company subsidiary that is not wholly-owned by the Company becoming a wholly-owned
subsidiary of the Company shall not be considered a "Fundamental Transaction" and shall not otherwise trigger any adjustment
or rights under this Warrant. “Successor Entity” means one or more Person or Persons (or, if so elected by the
Holder, the Company or Parent Entity (as defined below)) formed by, resulting from or surviving any Fundamental Transaction or
one or more Person or Persons (or, if so elected by the Holder, the Company or the Parent Entity) with which such Fundamental Transaction
shall have been entered into. “Parent Entity” of a Person means an entity that, directly or indirectly, controls
the applicable Person, including such entity whose common stock or equivalent equity security is quoted or listed on a Trading
Market, or, if there is more than one such Person or such entity, such Person or entity with the largest public market capitalization
as of the date of consummation of the Fundamental Transaction.

f) Calculations.
All calculations under this Section 3 shall be made to the nearest cent or the nearest 1/100th of an ADS, as the case may be. For
purposes of this Section 3, the number of Ordinary Shares deemed to be issued and outstanding as of a given date shall be the sum
of the number of Ordinary Shares (excluding treasury shares, if any) issued and outstanding.


 


g) Notice
to Holder.


 


i. Adjustment
to Exercise Price. Whenever the Exercise Price is adjusted pursuant to any provision of this Section 3, the Company shall promptly
mail to the Holder a notice setting forth the Exercise Price after such adjustment and any resulting adjustment to the number of
Warrant ADSs and setting forth a brief statement of the facts requiring such adjustment.


 


ii. Notice
to Allow Exercise by Holder. If (A) the Company shall declare a dividend (or any other distribution in whatever form) on the
Ordinary Shares, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Ordinary Shares or
ADSs, (C) the Company shall authorize the granting to all holders of the Ordinary Shares or ADSs rights or warrants to subscribe
for or purchase any shares of capital stock of any class or of any rights, (D) the approval of any shareholders of the Company
shall be required in connection with any reclassification of the Ordinary Shares or ADSs, any consolidation or merger to which
the Company is a party, any sale or transfer of all or substantially all of the assets of the Company, or any compulsory share
exchange whereby the Ordinary Shares are converted into other securities, cash or property, or (E) the Company shall authorize
the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Company, then, in each case, the Company
shall cause to be mailed to the Holder at its last address as it shall appear upon the Warrant Register of the Company, at least
20 calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which
a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to
be taken, the date as of which the holders of the Ordinary Shares or ADSs of record to be entitled to such dividend, distributions,
redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, sale,
transfer or share exchange is expected to become effective or close, and the date as of which it is expected that holders of the
Ordinary Shares of record shall be entitled to exchange their Ordinary Shares for securities, cash or other property deliverable
upon such reclassification, consolidation, merger, sale, transfer or share exchange; provided that the failure to mail such notice
or any defect therein or in the mailing thereof shall not affect the validity of the corporate action required to be specified
in such notice. To the extent that any notice provided in this Warrant constitutes, or contains, material, non-public information
regarding the Company or any of the Subsidiaries, the Company shall simultaneously file such notice with the Commission pursuant
to a Report on Form 6-K. The Holder shall remain entitled to exercise this Warrant during the period commencing on the date of

Section 4.Transfer
of Warrant.


 


a) Transferability.
Pursuant to FINRA Rule 5110(g)(1), neither this Warrant nor any Warrant ADSs issued upon exercise of this Warrant shall be sold,
transferred, assigned, pledged or hypothecated, or be the subject of any hedging, short sale, derivative, put or call transaction
that would result in the effective economic disposition of the securities by any person for a period of 180 days immediately following
the date of effectiveness or commencement of sales of the offering pursuant to which this Warrant is being issued, except the transfer
of any security:


 


		i.	by operation of law or by reason of reorganization of the
Company;






 


		ii.	to any FINRA member firm participating in the offering and the officers and partners thereof, if all
securities so transferred remain subject to the lock-up restriction in this Section 4(a) for the remainder of the time period;






 


		iii.	if the aggregate amount of securities of the Company held by the underwriter and related persons do
not exceed 1% of the securities being offered;



 


		iv.	that is beneficially owned on a pro-rata basis by all equity owners of an investment fund, provided
that no participating member manages or otherwise directs investments by the fund, and participating members in the aggregate do
not own more than 10% of the equity in the fund; or






 


		v.	the exercise or conversion of any security, if all securities received remain subject to the lock-up
restriction in this Section 4(a) for the remainder of the time period.






 


Subject to
the foregoing restriction and subject to compliance with any applicable securities laws and the conditions set forth in Section
4(d) hereof and to the provisions of Section 4.1 of the Purchase Agreement, this Warrant and all rights hereunder are transferable,
in whole or in part, upon surrender of this Warrant at the principal office of the Company or its designated agent, together with
a written assignment of this Warrant substantially in the form attached hereto duly executed by the Holder or its agent or attorney
and funds sufficient to pay any transfer taxes payable upon the making of such transfer. Upon such surrender and, if required,
such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees, as applicable,
and in the denomination or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant
evidencing the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled. Notwithstanding anything
herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company unless the Holder
has assigned this Warrant in full, in which case, the Holder shall surrender this Warrant to the Company within three (3) Trading
Days of the date the Holder delivers an assignment form to the Company assigning this Warrant full. The Warrant, if properly assigned
in accordance herewith, may be exercised by a new holder for the purchase of Warrant ADSs without having a new Warrant issued.


 






    	 	11	 



     


    




 


b) New
Warrants. This Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid office of the
Company, together with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by
the Holder or its agent or attorney. Subject to compliance with Section 4(a), as to any transfer which may be involved in such
division or combination, the Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants
to be divided or combined in accordance with such notice. All Warrants issued on transfers or exchanges shall be dated the Initial
Exercise Date and shall be identical with this Warrant except as to the number of Warrant ADSs issuable pursuant thereto.


 


c) Warrant
Register. The Company shall register this Warrant, upon records to be maintained by the Company for that purpose (the “Warrant
Register”), in the name of the record Holder hereof from time to time. The Company may deem and treat the registered
Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and
for all other purposes, absent actual notice to the contrary.


 


d) Transfer
Restrictions. If, at the time of the surrender of this Warrant in connection with any transfer of this Warrant, the transfer
of this Warrant shall not be either (i) registered pursuant to an effective registration statement under the Securities Act and
under applicable state securities or blue sky laws or (ii) eligible for resale without volume or manner-of-sale restrictions or
current public information requirements pursuant to Rule 144, the Company may require, as a condition of allowing such transfer,
that the Holder or transferee of this Warrant, as the case may be, comply with the provisions of the Purchase Agreement, including
Section 4.13 thereof.


 


e) Representation
by the Holder. The Holder, by the acceptance hereof, represents and warrants that it is acquiring this Warrant and, upon any
exercise hereof, will acquire the Warrant ADSs issuable upon such exercise, for its own account and not with a view to or for distributing
or reselling such Warrant ADSs or any part thereof in violation of the Securities Act or any applicable state securities law, except
pursuant to sales registered or exempted under the Securities Act.

Section 5. Miscellaneous.


 


a) [RESERVED]


 


b) No
Rights as Shareholder Until Exercise. This Warrant does not entitle the Holder to any voting rights, dividends or other rights
as a shareholder of the Company prior to the exercise hereof as set forth in Section 2(d)(i), except as expressly set forth in
Section 3.


 


c) Loss,
Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably
satisfactory to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Warrant
ADSs, and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the case of
the Warrant, shall not include the posting of any bond), and upon surrender and cancellation of such Warrant or stock certificate,
if mutilated, the Company will make and deliver a new Warrant or stock certificate of like tenor and dated as of such cancellation,
in lieu of such Warrant or stock certificate.


 


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


 


e) Authorized
Shares.


 


The Company covenants
that, during the period the Warrant is outstanding, it will reserve from its authorized and unissued Ordinary Shares and a sufficient
number of shares to provide for the issuance of the Warrant ADSs and underlying Ordinary Shares upon the exercise of any purchase
rights under this Warrant. The Company further covenants that its issuance of this Warrant shall constitute full authority to its
officers who are charged with the duty of issuing the necessary Warrant Shares upon the exercise of the purchase rights under this
Warrant. The Company will take all such reasonable action as may be necessary to assure that such Warrant ADSs may be issued as
provided herein without violation of any applicable law or regulation, or of any requirements of the applicable Trading Market
upon which the Ordinary Shares and ADSs may be listed. The Company covenants that all Warrant Shares which may be issued upon the
exercise of the purchase rights represented by this Warrant will, upon exercise of the purchase rights represented by this Warrant
and payment for such Warrant ADSs in accordance herewith, be duly authorized, validly issued, fully paid and nonassessable and
free from all taxes, liens and charges created by the Company in respect of the issue thereof (other than taxes in respect of any
transfer occurring contemporaneously with such issue).


 






    	 	13	 



     


    




 


Except and
to the extent as waived or consented to by the Holder, the Company shall not by any action, including, without limitation, amending
its certificate of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this
Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions
as may be necessary or appropriate to protect the rights of Holder as set forth in this Warrant against impairment. Without limiting
the generality of the foregoing, the Company will (i) not increase the par value of any Warrant Shares above the amount payable
therefor upon such exercise immediately prior to such increase in par value, (ii) take all such action as may be necessary or appropriate
in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares upon the exercise of this Warrant
and (iii) use commercially reasonable efforts to obtain all such authorizations, exemptions or consents from any public regulatory
body having jurisdiction thereof, as may be, necessary to enable the Company to perform its obligations under this Warrant.


 


Before taking
any action which would result in an adjustment in the number of Warrant ADSs for which this Warrant is exercisable or in the Exercise
Price, the Company shall obtain all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any
public regulatory body or bodies having jurisdiction thereof.


 


f) Jurisdiction.
All questions concerning the construction, validity, enforcement and interpretation of this Warrant shall be determined in accordance
with the provisions of the Purchase Agreement.


 


g) Restrictions.
The Holder acknowledges that the Warrant Shares and Warrant ADSs acquired upon the exercise of this Warrant, if not registered
and the Holder does not utilize cashless exercise, will have restrictions upon resale imposed by state and federal securities laws.


 


h) Nonwaiver
and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder shall operate
as a waiver of such right or otherwise prejudice the Holder’s rights, powers or remedies, notwithstanding the fact that all
rights hereunder terminate on the Termination Date. If the Company willfully and knowingly fails to comply with any provision of
this Warrant, which results in any material damages to the Holder, the Company shall pay to the Holder such amounts as shall be
sufficient to cover any costs and expenses including, but not limited to, reasonable attorneys’ fees, including those of
appellate proceedings, incurred by the Holder in collecting any amounts due pursuant hereto or in otherwise enforcing any of its
rights, powers or remedies hereunder.


 


i) Notices.
Any notice, request or other document required or permitted to be given or delivered to the Holder by the Company shall be delivered
in accordance with the notice provisions of the Purchase Agreement.


 






    	 	14	 



     


    




 


j) Limitation
of Liability. No provision hereof, in the absence of any affirmative action by the Holder to exercise this Warrant to purchase
Warrant ADSs, and no enumeration herein of the rights or privileges of the Holder, shall give rise to any liability of the Holder
for the purchase price of any Ordinary Shares or ADSs or as a shareholder of the Company, whether such liability is asserted by
the Company or by creditors of the Company.


 


k) Remedies.
The Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled
to specific performance of its rights under this Warrant. The Company agrees that monetary damages would not be adequate compensation
for any loss incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees to waive and not to assert
the defense in any action for specific performance that a remedy at law would be adequate.


 


l) Successors
and Assigns. Subject to applicable securities laws, this Warrant and the rights and obligations evidenced hereby shall inure
to the benefit of and be binding upon the successors and permitted assigns of the Company and the successors and permitted assigns
of Holder. The provisions of this Warrant are intended to be for the benefit of any Holder from time to time of this Warrant and
shall be enforceable by the Holder or holder of Warrant ADSs.


 


m) Amendment.
This Warrant may be modified or amended or the provisions hereof waived with the written consent of the Company and the Holder.


 


n) Severability.
Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective and valid under applicable
law, but if any provision of this Warrant shall be prohibited by or invalid under applicable law, such provision shall be ineffective
to the extent of such prohibition or invalidity, without invalidating the remainder of such provisions or the remaining provisions
of this Warrant.


 


o) Headings.
The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose, be deemed a part of
this Warrant.
