Schedule 1

Thomas E. Donilon

Explanation of responses:

(1)   7,500 options are currently exercisable; the balance vests on September 7, 2003.
(2)   7,680 options are currently exercisable; the balance vests on November 16, 2003.
(3)   Vesting of the options is contingent upon the achievement of an aggressive earnings per share (“EPS”) goal established in January 2000. If EPS equals or exceeds $6.46 per share by December 31, 2003, the options will become exercisable in January 2004. If the EPS goal is not met, then the options instead will vest and become exercisable in 25 percent annual increments beginning in January 2005. However, if the EPS goal is not met, the Board of Directors has retained the discretion to reduce or eliminate future compensation awards to offset this vesting.
(4)   17,805 options are currently exercisable; 8,902 options vest on November 21, 2003; and 8,903 options vest on November 21, 2004.
(5)   11,183 options are currently exercisable; and 11,184 options vest on November 20, 2003, November 20, 2004, and November 20, 2005.
(6)   The options vest in four annual installments as follows: 18,898 options vest on January 21, 2004 and 18,899 options vest on January 21, 2005, January 21, 2006, and January 21, 2007.
