Effective December 31, 2004, the Prior Plan was frozen and no new contributions will be made to it; provided, however, that any deferrals of Director’s Fees made under the Prior Plan before January 1, 2005 continue to be governed by the terms and conditions of the Prior Plan as in effect on December 31, 2004 or on the date of any later amendment, provided that such amendment is not a material modification of the Prior Plan under Section 409A. Deferred Equity-Based Awards are subject to the terms and conditions of this Plan.
