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.

The reporting person no longer has a reportable beneficial ownership in 80
shares of common stock owned by his son and included in prior ownership reports.
 This report is to disclaim beneficial ownership - it is not a sale of stock.

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