 Notwithstanding the foregoing, the Holder may elect to receive, without payment by the Holder of
the aggregate Exercise Price in respect of the Ordinary Shares to be acquired, Ordinary Shares of equal value to the value of this Warrant by the surrender of this Warrant together with a Notice of Exercise, duly executed, to the Company. Thereupon,
the Company shall issue to the Holder such number of Ordinary Shares as is computed using the following formula: 
  

			
	X = Y x (A-B)	  	
	A    	  	

 Where: 

X = the number of Ordinary Shares to which the Holder is entitled upon such cashless exercise; 

Y = the total number of Ordinary Shares covered by this Warrant for which the Holder has surrendered purchase rights at such time for cashless
exercise (including both shares to be issued to the Holder and shares as to which the purchase rights are to be canceled as payment therefor); 

A = the Fair Market Value of one Ordinary Share (at the date of exercise); and 

B = the Exercise Price in effect under this Warrant at the time the cashless exercise election is made. 

Subject to compliance with applicable laws and regulations, upon the exercise of the purchase rights represented by this Warrant, a
certificate or certificates for the number of Exercise Shares so purchased, registered in the name of the Holder or a Permitted Transferee of the Holder, if the Holder so designates, shall be issued and delivered to the Holder within a reasonable
time after the purchase rights represented by this Warrant shall have been so exercised (in whole). 
 The person in whose name any
certificate or certificates for Exercise Shares are to be issued (if the Exercise Shares are issued in certificated form) upon exercise of this Warrant shall be deemed to have become the holder of record of such shares on the date on which this
Warrant was exercised in respect of such Exercise Shares and payment of the Exercise Price was made, irrespective of the date of delivery of such certificate or certificates, except that, if the date of such exercise and payment is a date when the
share transfer books of the Company are closed, such person shall be deemed to have become the holder of such shares at the close of business on the next succeeding date on which the share transfer books are open. The person in whose name any
Exercise Shares are first registered (if the Exercise Shares are issued in uncertificated form) upon exercise of this Warrant shall be deemed to have become the holder of record of such shares on the date on which this Warrant was exercised in
respect of such Exercise Shares and payment of the Exercise Price was made, irrespective of the date that such person is registered as the holder of such Exercise Shares in the register of members of the Company, except that, if the date of such
exercise and payment is a date when the share transfer books of the Company are closed, such person shall be deemed to have become the holder of such shares at the close of business on the next succeeding date on which the share transfer books are
open.

	3.	Covenants of the Company 

  

	3.1	Covenants as to Exercise Shares. The Company covenants and agrees that all Exercise Shares that may be issued upon the exercise of the purchase rights represented by this Warrant will, upon issuance, be validly
issued and outstanding, and free from all taxes, liens and charges with respect to the issuance thereof. The Company further covenants and agrees that the Company will at all times during the Exercise Period, have authorized and reserved, free from
preemptive rights, a sufficient number of shares of the series of equity securities comprising the Exercise Shares to provide for the exercise of the purchase rights represented by this Warrant. If at any time during the Exercise Period the number
of authorized but unissued shares of such series of the Company’s equity securities shall not be sufficient to permit exercise of this Warrant, the Company will take such corporate action as may, in the opinion of its counsel, be necessary to
increase its authorized but unissued shares of such series of the Company’s equity securities to such number of shares as shall be sufficient for such purposes. 


 

	3.2	Notices of Record Date. In the event of any taking by the Company of a record of the holders of the shares of the series of equity securities comprising the Exercise Shares for the purpose of determining the
holders thereof who are entitled to receive any dividend or other distribution, the Company shall mail to the Holder, at least ten (10) days prior to the Record Date (as defined below), a notice specifying the date on which any such record is
to be taken for the purpose of such dividend or distribution (the “Record Date”). 

  

	4.	Representations of Holder 

  

	4.1	Acquisition of Warrant for Personal Account. The Holder represents and warrants that it is acquiring this Warrant and the Exercise Shares solely for its account for investment and not with a view to or for sale
or distribution of this Warrant or such Exercise Shares or any part thereof. The Holder also represents that the entire legal and beneficial interests of this Warrant and the Exercise Shares the Holder is acquiring is being acquired for, and will be
held for, its account only. 

  

	4.2	Securities Are Not Registered 

  

	 	(a)	The Holder understands that this Warrant and the Exercise Shares have not been registered under the U.S. Securities Act of 1933, as amended (the “Act”), on the basis that no distribution or public
offering of the securities of the Company is to be effected. The Holder realizes that the basis for the exemption may not be present if, notwithstanding its representations, the Holder has a present intention of acquiring the securities for a fixed
or determinable period in the future, selling (in connection with a distribution or otherwise), granting any participation in, or otherwise distributing the securities. The Holder has no such present intention. 


 

	 	(b)	The Holder recognizes that this Warrant and the Exercise Shares must be held indefinitely unless they are subsequently registered under the Act or an exemption from such registration is available. The Holder recognizes
that the Company has no obligation to register this Warrant or the Exercise Shares, or to comply with any exemption from such registration. 


  
 - 5 - 









	 	(c)	The Holder acknowledges that this Warrant and the Exercise Shares acquired upon the exercise of this Warrant, if not registered for resale under the Act, will have restrictions upon resale imposed by state and federal
securities laws unless this Warrant or the Exercise Shares acquired upon exercise of this Warrant, as applicable, are sold under an exemption from registration, including, without limitation, Rule 144 under the Act (if available).


  

	 	(d)	The Holder acknowledges that the Company may cause the legend set forth on the first page of this Warrant to be set forth on this Warrant or any Warrant issued in place of this Warrant, and, if required, a similar
legend on any security issued or issuable upon exercise of this Warrant, unless, (i) in the reasonable opinion of counsel for the Company, such legend is unnecessary or (ii) Holder provides appropriate documentation to the Company
including, if reasonably requested, an opinion of counsel for the Holder, that such legend is unnecessary, and, in each case, the Company will cause such legend removed from the warrant or stock, as applicable. 


 

	5.	Adjustment of Exercise Price and Number of Exercise Shares. In the event of changes in the series of equity securities of the Company comprising the Exercise Shares by reason of share dividends, splits,
recapitalizations, reclassifications, combinations or exchanges of shares, separations, reorganizations, liquidations, or the like, the number and class of Exercise Shares available under this Warrant in the aggregate and the Exercise Price shall be
correspondingly adjusted to give the Holder of this Warrant, on exercise for the same Aggregate Exercise Price, the total number, class, and kind of shares as the Holder would have owned had this Warrant been exercised prior to the event and had the
Holder continued to hold such shares until after the event requiring adjustment. For purposes of this Section 5 and Section 7, the “Aggregate Exercise Price” shall mean the aggregate Exercise Price payable in connection
with the exercise in full of this Warrant (assuming no cashless exercise election). The form of this Warrant need not be changed because of any adjustment in the number of Exercise Shares subject to this Warrant. 


 

	6.	Fractional Shares. No fractional shares shall be issued upon the exercise of this Warrant as a consequence of any adjustment pursuant hereto. All Exercise Shares (including fractions) to be issued upon exercise
of this Warrant shall be aggregated for purposes of determining whether the exercise would result in the issuance of any fractional share. If, after aggregation, the exercise would result in the issuance of a fractional share, the Company shall, in
lieu of issuance of any fractional share, pay the Holder otherwise entitled to such fraction a sum in cash equal to the product resulting from multiplying the then current Market Price on the date of exercise by such fraction. 


 

	7.	 Reorganization. In the event, at any time during the Exercise Period, (i) any capital reorganization of the share capital of the Company
(other than a change in par value or from par value to no par value or no par value to par value or as a result of a transaction 



  
 - 6 - 









	 	
covered by Section 5 above) is consummated, (ii) the Company, directly or indirectly, in one or more related transactions effects any merger or consolidation of the Company with or into
another Person (as defined below) in which the Company is not the surviving entity or the shareholders of the Company immediately prior to such merger or consolidation do not own, directly or indirectly, at least 50% of the outstanding voting
securities of the surviving entity, (iii) 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, or (iv) any, direct or indirect, purchase offer, tender offer or exchange offer (whether by the Company or another Person) is completed pursuant to which all or substantially all of the holders of Ordinary Shares are permitted to
sell, tender or exchange their shares for other securities, cash or property and has been accepted by the holders of 50% or more of the outstanding Ordinary Shares (each a “Corporate Change”), then, as a condition of such Corporate
Change, lawful and adequate provisions shall be made by the Company whereby the Holder hereof shall thereafter have the right to purchase and receive (in lieu of the Exercise Shares of the Company immediately theretofore purchasable and receivable
upon the exercise of the purchase rights represented hereby) such shares in the capital, securities or other assets or property as would have been issuable or payable with respect to or in exchange for a number of Exercise Shares equal to the number
of Exercise Shares immediately theretofore purchasable and receivable upon the exercise of the purchase rights represented hereby, and the Exercise Price shall be appropriately adjusted so that the Aggregate Exercise Price after such Corporate
Change shall be equal to the Aggregate Exercise Price immediately prior to such Corporate Change. For purposes of this Section 7, “Person” means an individual, a limited liability company, a partnership, a joint venture, a
corporation, a trust, an unincorporated organization, any other entity and a government or any department or agency thereof. 

  

	8.	[RESERVED]. 

  

	9.	No Shareholder Rights. This Warrant in and of itself shall not entitle the Holder to any voting rights or other rights as a shareholder of the Company with respect to the Exercise Shares. 


 

	10.	Transfer of Warrant. This Warrant may be transferred only pursuant to a registration statement filed under the Act, or an exemption from such registration. Subject to such restrictions and to applicable laws, and
provided that the number of holders of the Warrants shall not exceed 10 (joint holders being counted as one person) or such greater number as may be permitted from time to pursuant to a consent issued to the Company pursuant to the Control of
Borrowing (Jersey) Order 1958, this Warrant and all rights hereunder are transferable in full by the Holder to any Permitted Transferee upon delivery of this Warrant and the form of assignment attached hereto to the Company, duly executed and
delivered directly or by duly authorized attorney. This Warrant shall not be exercised in part. 

  

	11.	 Lost, Stolen, Mutilated or Destroyed Warrant. If this Warrant is lost, stolen, mutilated or destroyed, the Company may, on such terms as to
indemnity or otherwise as it may reasonably impose (which shall, in the case of a mutilated Warrant, include the surrender 



  
 - 7 - 









	 	
thereof), issue a new Warrant of like denomination and tenor as this Warrant so lost, stolen, mutilated or destroyed. Any such new Warrant shall constitute an original contractual obligation of
the Company, whether or not the allegedly lost, stolen, mutilated or destroyed Warrant shall be at any time enforceable by anyone. 

  

	12.	Amendment. Any term of this Warrant may be amended or waived with the written consent of the Company and the Holder. Upon the effectuation of such amendment or waiver in conformance with this Section 12, the
Company shall promptly give written notice thereof to the record holders of this Warrant who have not previously consented thereto in writing.
