Stock Options, RSUs and PSUs:

In 2005, the Company adopted two new equity incentive plans, which were subsequently amended in January 2014 and in July 2018: the 2005 United States Equity Incentive Plan and the 2005 Israel Equity Incentive Plan together are referred to as the Equity Incentive Plans.

Under the Equity Incentive Plans, the Company may grant options to employees, officers and directors at an exercise price equal to at least the fair market value of the ordinary shares at the date of grant and are granted for periods not to exceed

seven years

. The Company grants under the Equity Incentive Plans options, Restricted Stock Units (“RSUs”) and Performance RSUs (“PSUs”) and can also grant a variety of other equity incentives. Options granted under the Equity Incentive Plans generally vest over a period of

four years

of employment. Options, RSUs and PSUs that are cancelled or forfeited before expiration become available for future grants. The number of PSUs granted to sales employees is equal to the amount of compensation earned (based on the employee’s level) divided by the fair value of the ordinary share at the grant date. RSUs and PSUs vest over a

four year

period of employment from the grant date. PSUs are subject to certain performance criteria; accordingly, compensation expense is recognized for such awards when it becomes probable that the related performance condition will be satisfied.

Under the Equity Incentive Plans, the Company’s

non-employee

directors receive an automatic annual option grant. Following the amendments to the Equity Incentive Plans in July 2018, commencing December 31, 2018, on December 31st of each year, the number of Reserved and Authorized Shares (as defined below) under both Equity Incentive Plans together shall be automatically reset on such date to equal

% of the sum of (i) the number of ordinary shares issued and outstanding on such date and (ii) the number of ordinary shares reserved and authorized under the Equity Incentive Plans for outstanding awards granted under the Equity Incentive Plans as of such date (provided, however, that in

event shall the number of Reserved and Authorized Shares be less than the number of ordinary shares reserved and authorized under the Equity Incentive Plans for outstanding awards granted under the Equity Incentive Plans as of such date).

The number of “Reserved and Authorized Shares” under the Equity Plans shall equal the sum of (i) the number of ordinary shares reserved and authorized under the Equity Incentive Plans for outstanding options, RSUs, PSUs and other awards granted under the Equity Incentive Plans as of such date, and (ii) the number of ordinary shares reserved, authorized and available for issuance under the Equity Incentive Plans on such date.
