Explanation of Responses:


These performances shares paid out in cash, per the vesting and payout date
approved by the Compensation Committee.  The performance shares were not
required to be reported at date of grant because the vesting is based in part on
factors other than stock price.

This option vests yearly in twenty-five percent increments beginning on
3/1/2004.
