Explanation of Responses:

( 1 )1 for 1 ( 2 )The RSUP4 award listed in Table II has been reported at 75% of the original grant amount, as that represents the minimum amount guaranteed to be paid out upon vesting. Because of performance targets achieved, the award was paid out on March 2, 2009, at a performance-adjusted rate of 125%. The shares coded "A" represent that portion attributable to this performance adjustment. The shares coded "F" were sold to cover income tax obligations associated with the payout. ( 3 )This transaction reflects the extension and vesting of phantom stock to retirement or other termination of employment under arrangements approved by the Compensation Committee. ( 4 )These transactions reflect the extension of the expiration date of phantom stock from 3/1/2009 to "retirement" under arrangements approved by the Compensation Committee and reflect the movement of stock from the Phantom 3/06D account to the "retirement" account. ( 5 )On February 17, 2009,the Board approved a March 2, 2009 performance-adjusted restricted stock unit grant to Mr. Marsh in the amount of 10,695 shares, of which 50% or 5,348 shares will be payable on March 2, 2012. Of these shares, 5,347 shares are subject to forfeiture if the performance goals are not met. The full grant can be adjusted upward by an additional 50% if the 3-year goals are achieved. ( 6 )These transactions reflect the extension of the expiration date of phantom stock from 3/1/2008 to "retirement" under arrangements approved by the Compensation Committee and reflect the movement of stock from the Phantom 3/05 account to the "retirement" account.
