Explanation of Responses:

1. This option vests in 25% increments starting one year from the date of grant (3/1/2004).

2. An option grant of 20,300 shares was inadvertently left out of the March 3, 2004 filing. This amendment corrects the error and reflects the current balance as of March 3, 2004.

3. This transaction was inadvertently filed on March 3, 2004. There was no acquisition of 1967.947 shares of Phantom 3/01D. This transaction shows the disposition of 2080.7779 shares of Phantom 3/01D with a conversion price of 1 and reflects the current balance of Phantom 3/01D shares as of March 3, 2004.

4. These transactions reflect the extension of the expiration date of phantom stock from 3/1/2004 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 3/01 account.
