Explanation of Responses:

1. Shares simultaneously acquired and disposed represent shares withheld to pay Medicare taxes in connection with the payment of a Performance Share Award and the reporting person's deferral of the remaining performance shares under the Issuer's Nonqualified Deferred Compensation Plan (NQDCP) (reported in Table II of this Form).

2. Based on a plan statement dated December 31, 2007.

3. The Deferred Stock Units were credited to the reporting person's account under the Issuer's NQDCP in lieu of a payment by the Issuer of performance shares under the Issuer's 2005 Stock Incentive Plan. The number of units credited to the reporting person's account was determined on a 1-for-1 basis equal to the number of shares of common stock that would have been paid, reduced by the number of shares having a value equal to the Issuer's Medicare tax withholding obligation as a result of the deferral of the payment of the shares. The units will be settled 100% in shares of the Issuer's common stock following the reporting person's termination of employment or such other date specified by the reporting person under the terms of the NQDCP.

4. The Deferred Stock Units reported on Form 4 dated 05/08/2007 were incorrectly reported as 13,501; the correct total should have been 14,979.
