(1) This line entry reflects the balance as of March 2, 2004. All Form 4 reports filed by the reporting person after March 2, 2004, but before the date this Form 4 was filed, did not take this particular transaction into account and, consequently, did not properly reflect the amount of securities then beneficially owned by the reporting person. After taking this and all subsequent transactions into account, the balance, as of March 14, 2005, is 67,444.
(2) Balance as of December 31, 2004.
(3) All of these options are vested and exercisable in full.
(4) Vesting of these options occurs on January 26 of each of the five years beginning in 2001, at a rate equal to the percent by which the Issuer's earnings per share for the prior fiscal year was of $31.2, subject to at least a 10% increase in the Issuer's earnings per share from the prior fiscal year, and with any portion of the option which has not been vested at January 26, 2005 becoming vested on January 26, 2009.
(5) One-fifth of these options vest on January 24 of each of the five years beginning in 2002.
(6) One-fifth of these options vest on January 23 of each of the five years beginning in 2003.
(7) One-fifth of these options vest on January 22 of each of the five years beginning in 2004.
