3.                                       Vesting.  The Option is only exercisable, in whole or in part, on or before the Expiration Date and then only with respect to the vested portion of the Option.

(a)                                  Except as otherwise provided in this Agreement and the Plan, the Option vests and becomes exercisable to purchase shares of Common Stock as set forth in the Notice of Grant.  Shares scheduled to vest on a certain date or upon the occurrence of a certain condition will not vest in accordance with any of the provisions of this Agreement unless you have been an employee (or other service provider) of the Company, a Subsidiary or an Affiliated Entity continuously from the Date of Grant until the date such vesting occurs.

If your employment (or other service) with the Company is terminated for Cause prior to the Expiration Date, the entire Option, whether or not vested, shall become void, shall be forfeited and shall terminate immediately upon your termination of employment (or other service).  For this purpose, Cause shall mean a conviction (or pleading nolo contendere) of a felony or termination of employment (or other service) due to a violation of the Company’s Code of Business Conduct and Ethics, as determined by the Committee (or its designee) in good faith (“Cause”).
