[Subject to paragraph 4 below, the Option, to the extent that there has been no termination of the Participant’s [employment] [service] and the Option has not otherwise expired or been forfeited, shall first become exercisable [insert schedule].]

4. Termination.

Unless earlier expired or forfeited, the Option shall, notwithstanding any other provision of this Agreement, expire in its entirety upon the fifth anniversary of the date hereof.

If the Participant’s employment or service with the Corporation or one of its Subsidiaries is terminated, the exercise period of the Option shall expire on the earliest of the following: (i) the time specified in paragraph 4 above; (ii) twelve (12) months after the last day that the Participant is employed by or provides services to the Corporation or one of its Subsidiaries; or (iii) immediately upon the Participant’s termination for “Cause” (as defined in the Plan).

Notwithstanding anything herein to the contrary, in the event Participant violates any of the restrictive covenants contained in any agreement executed in connection with Participant’s employment with or service to the Corporation or one of its Subsidiaries, as well as termination thereof, then the Option shall be forfeited and may not be exercised. The determination of whether such a violation has occurred will be determined by the Administrator in good faith and in its sole discretion.

6. Method of Exercise.

The Option may be exercised in whole or in part at any time during the term hereof by notice in the form required by the Corporation, together with payment of the aggregate exercise price and applicable withholding tax.
