“Effective
as of December 1, 2011, you will be eligible to receive monthly compensation according to the table below. Payments will be made
every month, starting on or before the ninth of the month following the commencement of your employment. You
acknowledge that your monthly compensation stated below includes remuneration for all allowances and benefits required by law,
by extension of the law, or any collective bargaining agreements (with the sole exception of travel allowances and meal allowances,
also described below), as follows:

	Type of Payment	Sum
	Base Salary	27,000 NIS
	Travel Allowance	Equal to intercity bus fare (“chofshi-chodshi”) (up to a maximum currently set at 510 NIS).
	Meals	Up to a maximum currently set at 14 NIS per meal, plus income tax, as appropriate for the portion subsidized by the Company.

or any law that may be enacted in its place, will not apply to you. You will not be entitled to remuneration according to the Work
Hours and Rest Law and acknowledge that your Base Salary has already been increased to include within it all payments which are
paid to an employee who is paid in accordance with the directives of the Work Hours and Rest Law. You are expected to work those
days and hours necessary for the proper performance of your duties.”

 

3.Except as expressly
provided in this Amendment #2, all of the terms and conditions of the Offer of Employment Letter remain unchanged, and the terms
and conditions of the Offer of Employment Letter as amended hereby remain in full force and effect.
