17.12 Minimum Vesting Periods. Except as set forth in Section 14 herein and notwithstanding any other provision set forth in the Plan to the contrary, (A) any Award (other than a Stock Option or SAR) that is not subject to performance criteria shall Vest over a service period of at least three years, with such vesting to occur in equal installments over such three year period, and (B) any Award (other than a Stock Option or SAR) that is subject to performance criteria shall Vest over a performance period of at least 12 months in one or more installments over that period.”
