XV. RESTRICTIONS AND FORFEITURE OF STOCK AWARDS
The Companys obligation to deliver stock held in escrow is subject to the condition that the employee remain an employee of the Company on active or authorized leave status or be under contract to provide services to the Company as provided in Section XVI hereof for the entire deferral and/or restriction period, including mandatory and optional deferrals. If the employee fails to meet this condition, the employees right to any such unpaid amounts or undelivered stock shall be forfeited. This provision may be waived by the Committee in exceptional circumstances. In the event an employee holding restricted shares ceases to be on active pay status during the restricted period for a period of more than six months, the restricted period shall be extended by a period of time equal to the length of the period of inactive status.
