In addition, fees paid to non-employee directors for each meeting of the Board in excess of six meetings per year will be $1,800 (no fee will be paid for the first six Board meetings), and fees paid to non-employee directors for each committee meeting will be $1,800. The Lead Independent Director and the chairman of each of the Audit, Compensation and Nominating/Corporate Governance committees will receive an additional annual retainer of $15,000. In addition, like the Company’s other directors, Mr. Jaggers has received an indemnification agreement, the terms of which are described in the Company’s Form 8-K filed September 18, 2006.
