Notwithstanding the foregoing, if a Non-Employee Director ceases to serve through one or more quarterly vesting dates due to death, disability, removal, resignation or retirement, the Compensation Committee shall have the discretion

Multiple Roles. If a Non-Employee Director serves in more than one of the roles noted in Section 2(b), he or she shall be entitled to receive compensation for each role.

In addition to the equity award set forth in Section 3(a), in consideration for the services performed in his capacity as the Chairman of the Board, the Chairman shall be granted, at the same time and on the same terms and conditions as the equity granted under Section 3(a) above, an equity award covering a number of ordinary shares having an approximate aggregate value of $100,000, provided, however, that if any Chairman is appointed in the middle of the term, then, in the discretion of the Compensation Committee, such director may be entitled to receive a prorated equity award on such terms and conditions, including a grant date, approved by the Compensation Committee.

Form of Equity Award. The equity award shall be made in the form of restricted share units (RSUs), provided, however, that it may be made in the form of time-based options upon notification by management to the Compensation Committee of the lack of RSU availability under the 2012 Plan (defined below).

Grant Date. The equity granted pursuant to Sections 3(a) and 3(b) shall be granted on March 5th, May 10th, August 10th, November 10th, or December 5th (or if the applicable grant date is not a trading day, the next trading day) on the date most closely following the AGM.

Vesting; Accelerated Vesting.

Notwithstanding the foregoing, if a Non-Employee Director ceases to serve through the vesting date due to death, disability, removal, resignation or retirement, the Compensation Committee shall have the discretion to accelerate the vesting of the equity as of the date of such Non-Employee Director’s cessation of service. Otherwise, such equity shall be forfeited.

Policy Subject to Amendment, Modification and Termination.
