Explanation of Responses:

1. Shares acquired represent payment of a Performance Share Award ("PSA"), and shares disposed of represent shares withheld from the PSA to pay withholding taxes.

2. The amount reported includes: 978 shares owned directly that are subject to certain restrictions (including possible forfeiture) applicable to restricted stock grants under the Issuer's 2000 Stock Incentive Plan; 419.396 directly-owned shares held in the Issuer's Employee Stock Purchase Plan as of March 31, 2003; and 983.778 indirectly-owned shares allocated to the reporting person's account under the Issuer's 401(k) plan as of April 30, 2003.

3. The Phantom Stock Units were acquired through the deferral of a bonus under the Issuer's Nonqualified Deferred Compensation Plan. The amount of the deferral corresponded to a price of $49.36/share. The units are deemed to convert on a 1-for-1 basis with common stock but will be settled 100% in cash following the reporting person's termination of employment or such other date specified by the reporting person. However, following a one-year holding period which expires May 6, 2004, the reporting person may elect to transfer funds out of the Phantom Stock account (known as the restricted bonus sub-account) and into other Plan accounts.

4. The actual expiration date is not known at this time. Due to technical constraints resulting from the Release 8.5 upgrade to the EDGAR system, the staff of the SEC has designated that "08/08/1988" be entered until such time as the system is modified. The units are to be settled 100% in cash following the reporting person's termination of employment or such other date specified by the reporting person. However, the reporting person may elect to transfer funds into other investment accounts within the Nonqualified Deferred Compensation Plan at any time.
