The determinations of the Committee shall be final and binding in all matters relating to the Program.  The Committee shall have authority to determine the terms and conditions of Bonuses.

Section 1.3.  Eligible Persons.  Bonuses may be granted to employees of the Corporation.  The Committee or, if applicable, its delegate(s) shall determine the employees who are eligible to participate in the Program ("Participants").

In general, for the Program, the Performance Period is the Corporation's fiscal year (October 1 – September 30).
