At the time any Award is made under this Article X, the Company and the Holder shall enter into a Restricted Stock Unit Agreement setting forth each of the matters contemplated thereby and such other matters as the Committee may determine to be appropriate. The Restricted Stock Unit Agreement shall set forth the individual service-based vesting requirement which the Holder would be required to satisfy before the Holder would become entitled to distribution pursuant to Section 10.3 and the number of Units awarded to the Holder. Such conditions shall be sufficient to constitute a “substantial risk of forfeiture” as such term is defined under Section 409A of the Code. At the time of such Award, the Committee may, in its sole discretion, prescribe additional terms and conditions or restrictions relating to Restricted Stock Unit Awards in the Restricted Stock Unit Agreement, including, but not limited to, rules pertaining to the effect of Termination of Service prior to expiration of the applicable vesting period. The terms and conditions of the respective Restricted Stock Unit Agreements need not be identical.
