(1)	The securities represent deferred shares of the issuer's common stock credited to the reporting person's deferred compensation account pursuant to dividend equivalent rights. Those rights resulted initally in the addition of a cash sum to the account equal to the dividends which would have been paid during the first quarter of 2007 on shares covered by the reporting person's April 2003 Stock Option and the deferred stock credited thereunder pursuant to dividend equivalent rights had all such stock actually been issued and outstanding on March 1, 2007, the dividend payment date. The accumulated sum was then converted into additional shares of deferred stock on the first business day following the end of the 2007 first quarter based on the closing selling price of the issuer's common stock on March 1, 2007, on which date actual dividends on the common stock were paid during the first quarter of 2007.
(2)	Includes 207 shares of Common Stock, 2,064 shares underlying restricted stock units, and 929 shares of deferred stock which may be subject in whole or in part to vesting schedules tied to the reporting person's continued service with the issuer and which will be distributed as actual shares of Common Stock of the issuer either at the time of vesting or at a specified time thereafter (including termination of service with the issuer).
