In consideration of
the premises and mutual covenants contained herein and for other good and valuable consideration, the receipt, validity and sufficiency
of which is hereby acknowledged, the parties agree as follows:



1.                 
Grant of Option. Subject to the terms and conditions of this Agreement, the Company confirms that it granted to the Optionee
the right (the “Option”) to purchase all or any part of an aggregate of 100,000 (one hundred thousand)
ordinary shares of the Company, par value $0.001 per share (“Common Stock”).



2.                 
Vesting Schedule. This Option shall vest based on activities and/or services performed, as set out in Addendum A.



3.                 
Exercise Price. The price of each share of Common Stock purchased pursuant to this Option shall be U.S. $0.01.



4.                 
Exercise of Option. The Optionee may exercise the Option, in whole or in part, with respect to any whole number of vested
shares of Common Stock subject to the Option. The Optionee shall exercise the Option by giving the Company written notice, in a
form prescribed by the Company. Such notice shall specify the number of shares of Common Stock to be purchased and shall be accompanied
by payment, in U.S. dollars, in cash, by wire transfer of immediately available funds, or by certified check or by official bank
check, of an amount equal to the Option exercise price per share of Common Stock, multiplied by the number of shares of Common
Stock as to which the Option is being exercised; provided, however, that (i) [this Option may be exercised on a cashless basis,
in whole or in part, in accordance with the Cashless Exercise Formula (as defined below), and (ii) the purchase price may be paid
by the delivery of funds equal to the purchase price by a broker, in accordance with Regulation T promulgated by the Board of Governors
of the Federal Reserve System or as otherwise may be permissible by law. The board of directors of the Company (the “Board”)
may impose from time to time such limitations as it deems appropriate on the exercise of the Option.



For purposes of this
Agreement, the term “Cashless Exercise Formula” means:



N’= (N x (P -
E)) / P



where:



N’ = the
adjusted number of shares of Common Stock issuable upon cashless exercise of the Option.



N = the current
number of shares of Common Stock issuable upon exercise of the Option.



E = the Exercise
Price on the date of cashless exercise of the Option.



P = the average
reported last sales price of the Common Stock for the last 10 trading days ending on the third business day prior to the date on
which notice of cashless exercise is given.

in Section 4, to the broker) a certificate or certificates for such shares of Common Stock purchased pursuant to the Option; provided,
however, that the time of such delivery may be postponed by the Company for such period of time as the Company may require for
compliance with any law, rule or regulation applicable to the issuance or transfer of shares of Common Stock.



6.                 
Payment of Taxes. Prior to or concurrently with delivery by the Company to the Optionee of a certificate or certificate(s)

Certain Adjustments.



(a)               
In the event that the Company or the division, subsidiary or other affiliated entity for which the Optionee performs services
is sold (including a stock or an asset sale), spun off, merged, consolidated, reorganized or liquidated, the Board may determine
that (i) the Option shall be assumed, or a substantially equivalent Option shall be substituted, by an acquiring or succeeding

provide that the Option shall terminate immediately prior to the consummation of the transaction unless exercised by the Optionee

of a sale or similar transaction under the terms of which holders of Common Stock receive a payment for each share of Common Stock
surrendered in the transaction (the “Sales Price”), make or provide for a payment to each Optionee equal
to the amount by which (A) the Sales Price times the number of shares of Common Stock subject to the Option (to the extent such
Option is then exercisable) exceeds (B) the aggregate exercise price for all such shares of Common Stock; or (iv) may make such
other equitable adjustments as the Board deems appropriate.



(b)              
In the event of any stock dividend or split, recapitalization, combination, exchange or similar change affecting the Common Stock,
the Board shall make any or all of the following adjustments as it deems appropriate to equitably reflect such event: (i) adjust
the option price to be paid for any or all shares subject to this Agreement, (ii) adjust the number of shares of Common Stock
(or such other security as is designated by the Board) subject to this Agreement and (iii) make any other equitable adjustments
or take such other equitable action as the Board, in its discretion, shall deem appropriate.



(c)               
Any and all adjustments or actions taken by the Board pursuant to this Section shall be conclusive and binding for all purposes.



10.             
No Restriction on the Right of the Company to Effect Corporate Changes. The Option granted hereunder shall not affect in
any way the right or power of the Company or its stockholders to make or authorize any or all adjustments, recapitalizations, reorganizations
or other changes in the Company’s capital structure or its business, or any merger or consolidation of the Company, or any
issue of stock or of options, warrants or rights to purchase stock or of bonds, debentures, preferred or prior preference stocks
whose rights are superior to or affect the Common Stock or the rights of holders thereof or which are convertible into or exchangeable
for Common Stock, or the dissolution or liquidation of the Company, or any sale or transfer of all or any part of its assets or
business, or any other corporate act or proceeding, whether of a similar character or otherwise.
