The Nonqualified Stock Option Agreement shall state when the Nonqualified Stock Option becomes exercisable ( i.e. “vests”) and, if applicable in the Administrator’s discretion, shall describe the Performance Objectives and Performance Period upon which vesting is based, the manner in which performance shall be measured and the extent to which partial achievement of the Performance Objectives may result in vesting of the Option. The Participant may exercise the Nonqualified Stock Option, in full or in part, upon or after the vesting date of such Option (or portion thereof); provided, however, that the Participant may not exercise a Nonqualified Stock Option after the maximum term of such Option, as such term is specified in the Nonqualified Stock Option Agreement. Unless otherwise determined by the Administrator and specified in the Agreement governing the Award, no Nonqualified Stock Option shall be exercisable during a term of more than ten (10) years after the date on which it is granted. The Administrator may accelerate the exercisability of any Nonqualified Stock Option granted hereunder which is not immediately exercisable as of the date of grant.
