Explanation of Responses:

1. 1 for 1

2. These transactions reflect the extension of the expiration date of phantom stock from 3/1/2005 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 3/02D.

3. The performance based restricted stock units, which were granted March 1, 2005, will earn dividends. The reported number of units reflects 75% of the total amount of units granted, and is the amount the employee is guaranteed to realize. The actual number realized could be 25% higher or 25% lower than the total amount of units granted.
