increments, from time to time and at any time, until the Option lapses or terminates. If the Optionee’s exercise of any Option
would require the Grantor to issue a fractional Share, the Grantor will not be required to issue such fractional Share but it shall pay
the Optionee in cash the value of such fractional Share. Except as set forth in Section 5, all unexercised Options (whether or not vested)
shall lapse and forever terminate on ____________, 20__.

(c) Notwithstanding
the foregoing, in the event the market capitalization of the Company shall exceed: (i) $______ million, [one-half] (rounded to
the nearest Share), or _______ Shares shall vest and become exercisable immediately thereafter; and (ii) $_______ billion, the remaining
[one-half] (rounded to the nearest Share), or _______ Shares shall vest and become exercisable immediately.

 

(d) Notwithstanding
the foregoing, in the event of a Corporate Transaction (as defined in Section 4.2(b) of the Plan) the Option shall be assumed by the

and be fully vested and immediately exercisable upon completion of the Corporation Transaction.

 

		4.	Manner
of Exercise.

price, in cash or by check and (c) the payment of any withholding tax to the Company, will be required to withhold as a result of the
exercise of the Option. The Purchase Price of the shares of Stock as to which the Option is exercised shall be paid in full at the time
of exercise by any approved method set forth in paragraphs (a) through (e) of Section 6.5 of the Plan. The Optionee shall not have any
of the rights of a shareholder with respect to the Stock covered by the Option until the date of the issuance of a stock certificate
to Optionee for such shares of Stock. An Optionee shall have the right to dividends and other rights of a stockholder with respect to
ordinary shares purchased upon exercise of an Option at such time as the Optionee has given written notice of exercise and has paid in
full for such shares and has satisfied such conditions that may be imposed by the Grantor with respect to the withholding of taxes.

 

Subject
to the terms and conditions hereof, the Options shall be exercisable by notice to the Grantor on the form provided by the Grantor, a
copy of which is attached hereto. In the event that the Options are being exercised by any person or persons other than the Optionee,

of the term of the Option.

 

    2

     

    

 

(b) In
the event that the employment of the Optionee shall terminate for cause, the Option shall be cancelled immediately. Termination “for
cause” shall mean dismissal for commission of any act of a theft, embezzlement or fraud involving the Grantor or any member of
the Parent Participating Group or otherwise, or a breach of fiduciary duty to the Grantor or any member of the Parent Participating Group.
If the employment of the Optionee shall be suspended pending an investigation of whether or not the Optionee shall be terminated for
cause, all of the Optionee’s rights under the Option granted hereunder likewise shall be suspended during the period of investigation.

the event of the death or total disability of the Optionee while an employee of Grantor or within three months after the termination

granted shall be exercisable in whole or in part during the Optionee’s lifetime only by the Optionee or his guardian or legal representative.

and privileges conferred by this Option shall be null and void and this Option and the rights and privileges conferred by this Option
shall immediately terminate and become null and void.

 

		7.	Stock
as Investment.

accepting the Option herein granted, the Optionee agrees for himself and his heirs and legatees that, unless the Shares are sold pursuant
to an effective registration statement under the Securities Act of 1933 (the “Securities Act”) or an exemption from
registration, all Shares purchased hereunder shall be acquired for investment purposes only and not for sale or distribution, and upon
the issuance of any or all of the Shares issuable under the Option, the Optionee, or his heirs or legatees receiving such Shares, shall
deliver to the Grantor a representation in writing, that unless such Shares have been registered for resale they are being acquired in
good faith for investment purposes only and not for sale or distribution. Grantor may place a “stop transfer” order with
respect to such Shares with its transfer agent and place an appropriate restrictive legend on the stock certificate evidencing such Shares.

of ordinary shares as to which the Option may be exercised shall be correspondingly adjusted by the Grantor, and the Purchase Price shall
be adjusted so that the product of the Purchase Price immediately after such event multiplied by the number of options subject to this
Agreement immediately after such event shall be equal to the product of the Purchase Price multiplied by the number of Shares subject
to this Agreement immediately prior to the occurrence of such event.

 

(b) In
