    4


     


    

 


6.1.3 Replacement
of Ordinary Shares upon Reorganization, etc. In case of any reclassification or reorganization of the outstanding Ordinary
Shares other than a change covered by Section 6.1.1 or Section 6.1.2 hereof or that solely affects
the par value of such Ordinary Shares, or in the case of any share reconstruction or amalgamation or consolidation of the Company
with or into another corporation (other than a consolidation or share reconstruction or amalgamation in which the Company is the
continuing corporation and that does not result in any reclassification or reorganization of the outstanding Ordinary Shares),
or in the case of any sale or conveyance to another corporation or entity of the property of the Company as an entirety or substantially
as an entirety in connection with which the Company is dissolved, the Holder of this Purchase Warrant shall have the right thereafter
(until the expiration of the right of exercise of this Purchase Warrant) to receive upon the exercise hereof, for the same aggregate
Exercise Price payable hereunder immediately prior to such event, the kind and amount of ordinary shares or other securities or
property (including cash) receivable upon such reclassification, reorganization, share reconstruction or amalgamation, or consolidation,
or upon a dissolution following any such sale or transfer, by a Holder of the number of Ordinary Shares of the Company obtainable
upon exercise of this Purchase Warrant immediately prior to such event; and if any reclassification also results in a change in
Ordinary Shares covered by Section 6.1.1 or Section 6.1.2, then such adjustment shall be made pursuant
to Section 6.1.1, Section 6.1.2 and this Section 6.1.3. The provisions of this Section
6.1.3 shall similarly apply to successive reclassifications, reorganizations, share reconstructions or amalgamations,
or consolidations, sales or other transfers.


 


6.1.4  Fundamental
Transaction. If, at any time while this Purchase Warrant is outstanding, the Company enters into the following transactions
with another Person or group of Persons whereby such other Person or group acquires more than 50% of the outstanding Ordinary Shares
(not including any Ordinary Shares held by the other Person or other Persons making or party to, or associated or affiliated with,
the other Persons making or party to such stock or share purchase agreement or other business combination): (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
are permitted to sell, tender or exchange their shares for other securities, cash or property and has been accepted by the holders
of 50% or more of the outstanding Ordinary Shares, (iv) the Company, directly or indirectly, in one or more related transactions
effects any reclassification, reorganization or recapitalization of the Ordinary Shares or any compulsory share exchange pursuant
to which the Ordinary Shares is 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, spinoff or scheme of arrangement) with another Person or group
of Persons (each a “Fundamental Transaction”), then, upon any subsequent exercise of this Purchase Warrant,
the Holder shall have the right to receive, for each Purchase Warrant Share that would have been issuable upon such exercise immediately
prior to the occurrence of such Fundamental Transaction, the number Ordinary Shares of the successor or acquiring corporation or
of the Company, if it is the surviving corporation, and any additional or alternative consideration (the “Alternative
Consideration”) receivable as a result of such Fundamental Transaction by a holder of the number of Ordinary Shares for
which this Purchase Warrant is exercisable immediately prior to such Fundamental Transaction. For purposes of any such exercise,
the determination of the Exercise Price shall be appropriately adjusted to apply to such Alternative Consideration based on the
amount of Alternative Consideration issuable in respect of one Ordinary Share in such Fundamental Transaction, and the Company
shall apportion the Exercise Price among the Alternative Consideration in a reasonable manner reflecting the relative value of
any different components of the Alternative Consideration. If holders of Ordinary Shares 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 Alternative
Consideration it receives upon any exercise of this Purchase 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 Purchase Warrant, and to deliver to the Holder in exchange
for this Purchase Warrant a security of the Successor Entity evidenced by a written instrument substantially similar in form and
substance to this Purchase Warrant which is exercisable for a corresponding number of shares of capital stock of such Successor
Entity (or its parent entity) equivalent to the Ordinary Shares acquirable and receivable upon exercise of this Purchase 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 number of shares of capital stock and such exercise price being for the purpose of
protecting the economic value of this Purchase Warrant immediately prior to the consummation of such Fundamental Transaction).
Upon the occurrence of any such Fundamental Transaction, the Successor Entity shall succeed to, and be substituted for (so that
from and after the date of such Fundamental Transaction, the provisions of this Purchase Warrant and the other Transaction Documents
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 Purchase Warrant and the other Transaction Documents
with the same effect as if such Successor Entity had been named as the Company herein.


 






    5


     


    

 


6.1.5  Changes
in Form of Purchase Warrant. This form of Purchase Warrant need not be changed because of any change pursuant to this Section
6.1, and Purchase Warrants issued after such change may state the same Exercise Price and the same number of Ordinary Shares
as are stated in the Purchase Warrants initially issued pursuant to this Agreement. The acceptance by any Holder of the issuance
of new Purchase Warrants reflecting a required or permissive change shall not be deemed to waive any rights to an adjustment occurring
after the date hereof or the computation thereof.


 


6.2 Substitute
Purchase Warrant. In case of any consolidation of the Company with, or share reconstruction or amalgamation of the Company
with or into, another corporation (other than a consolidation or share reconstruction or amalgamation which does not result in
any reclassification or change of the outstanding Ordinary Shares), the corporation formed by such consolidation or share reconstruction
or amalgamation shall execute and deliver to the Holder a supplemental Purchase Warrant providing that the holder of each Purchase
Warrant then outstanding or to be outstanding shall have the right thereafter (until the stated expiration of such Purchase Warrant)
to receive, upon exercise of such Purchase Warrant, the kind and amount of Ordinary Shares and other securities and property receivable
upon such consolidation or share reconstruction or amalgamation, by a holder of the number of Ordinary Shares of the Company for
which such Purchase Warrant might have been exercised immediately prior to such consolidation, share reconstruction or amalgamation,
sale or transfer. Such supplemental Purchase Warrant shall provide for adjustments which shall be identical to the adjustments
provided for in this Section 6. The above provision of this Section 6 shall similarly apply to successive
consolidations or share reconstructions or amalgamations. 


 


6.3 Elimination
of Fractional Interests. The Company shall not be required to issue certificates representing fractions of Ordinary Shares
upon the exercise of the Purchase Warrant, nor shall it be required to issue scrip or pay cash in lieu of any fractional interests,
it being the intent of the parties that all fractional interests shall be eliminated by rounding any fraction up or down, as the
case may be, to the nearest whole number of Ordinary Shares or other securities, properties or rights.


 


7. Reservation
and Listing. The Company shall at all times reserve and keep available out of its authorized Ordinary Shares, solely for the
purpose of issuance upon exercise of this Purchase Warrant, such number of Ordinary Shares or other securities, properties or rights
as shall be issuable upon the exercise thereof. The Company covenants and agrees that, upon exercise of this Purchase Warrant and
payment of the Exercise Price therefor, in accordance with the terms hereby, all Ordinary Shares and other securities issuable
upon such exercise shall be duly and validly issued, fully paid and non-assessable and not subject to preemptive rights of any
shareholder. The Company further covenants and agrees that upon exercise of this Purchase Warrant and payment of the exercise price
therefor, all Ordinary Shares and other securities issuable upon such exercise shall be duly and validly issued, fully paid and
non-assessable and not subject to preemptive rights of any shareholder. As long as this Purchase Warrant shall be outstanding,
the Company shall use its commercially reasonable efforts to cause all Ordinary Shares issuable upon exercise of this Purchase
Warrant to be listed (subject to official notice of issuance) on all national securities exchanges (or, if applicable, on the OTCQB
Market or any successor quotation system) on which the Ordinary Shares issued to the public in the Offering may then be listed
and/or quoted (if at all).


 


8. Certain
Notice Requirements.


 


8.1 Holder’s
Right to Receive Notice. Nothing herein shall be construed as conferring upon the Holders the right to vote or consent or to
receive notice as a shareholder for the election of directors or any other matter, or as having any rights whatsoever as a shareholder
of the Company. If, however, at any time prior to the expiration of the Purchase Warrants and their exercise, any of the events
described in Section 8.2 shall occur, then, in one or more of said events, the Company shall give written notice
of such event at least fifteen days prior to the date fixed as a record date or the date of closing the transfer books (the “Notice
Date”) for the determination of the shareholders entitled to such dividend, distribution, conversion or exchange of securities
or subscription rights, or entitled to vote on such proposed dissolution, liquidation, winding up or sale. Such notice shall specify
such record date or the date of the closing of the transfer books, as the case may be. Notwithstanding the foregoing, the Company
shall deliver to each Holder a copy of each notice given to the other shareholders of the Company at the same time and in the same
manner that such notice is given to the shareholders.

reconstruction or amalgamation) or a sale of all or substantially all of its property, assets and business shall be proposed.
