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.

These transactions reflect the extension of the expiration date of phantom stock
from 3/1/2003 to "retirement" or "other termination of employment" under
arrangements approved by the Compensation Committee, and reflects the stock
moving to the "retirement" account from the Phantom 3/00 account.

1 for 1

22,588.27 shares are vested (i.e. non-forfeited) immediately.  4,517.65 shares
become vested (i.e. non-forfeited) on 3/1/06.
