(i) Upon a Change in Control prior to the second Vesting Date (i.e., prior to March 22, 2015), the portion of the Option that was scheduled to vest on the first Vesting Date, if not then vested, and on the second Vesting Date shall accelerate and become fully vested and exercisable, subject to the Grantee’s continued employment in active service by the Company or one of its Affiliates or otherwise provides services as a member of the Board, or both, through the effective date of a Change in Control. The remaining portion of the Option shall be unaffected by the Change in Control.

(ii) Notwithstanding anything in this Agreement to the contrary, if (A) the Grantee’s employment terminates for any reason other than a termination by the Company or one of its Affiliates for Cause or by the Grantee without Good Reason, and the Grantee’s service as a member of the Board terminates for any reason other than termination by the Board for Cause or by the Grantee for any reason, and (B) the effective date of a Change in Control occurs during the period (x) beginning on the date of the

Grantee’s termination of employment or service, whichever is later, and (y) ending 90 days following such termination date, then immediately prior to the effective date of the Change in Control (and subject to the consummation of such Change in Control), then if the portion of the Option that was scheduled to vest on the first or second Vesting Date had not yet vested, such portion of the Option that would vest on the first Vesting Date, if not then vested, and the second Vesting Date shall vest in accordance with Section 2(b)(i) above as if the Change in Control had occurred immediately prior to such termination.”

“(i) Except as provided below in Section 5(a)(iii), if, prior to the second Vesting Date (i.e., March 22, 2015), (1) either the Grantee’s employment or service with the Company and its Affiliates is terminated by the Company, one of its Affiliates or the Board without Cause or due to the Grantee’s Disability, (2) the Grantee’s employment with the Company and its Affiliates is terminated by the Grantee for Good Reason or (3) either the Grantee’s employment or service with the Company and its Affiliates is terminated due to the Grantee’s death, the Option shall become fully vested and exercisable as of the date of such termination with respect to the portion of the Option Shares that would vest on the first and second Vesting Date to the extent then not vested.”

“(iv) Notwithstanding anything to the contrary in this Agreement, upon any termination of the Grantee’s employment with the Company and its Affiliates (even if the Grantee remains in service as a member of the Board or other non-employee capacity), the unvested portion of the Option shall be cancelled immediately and the Grantee shall immediately forfeit any rights to the Option Shares subject to such unvested portion, except with respect to 40% of the Option Shares which may vest or be eligible to vest in accordance with the terms herein, including Section 5(a)(i) and Section 5(a)(iii).”
