        <footnote id="F1">Pursuant to the Amended and Restated 1997 Directors' Stock and Deferred Fee Plan, the Reporting Person was granted a Restricted Stock Award of the number of shares of the Issuer's common stock having an aggregate Fair Market Value equal to $100,000 on the date of grant.  The Fair Market Value of each Restricted Stock Unit is equal to the closing price of the Issuer's common stock as reported by The New York Stock Exchange, Inc. on the date of grant, which was $22.70.  Each stock unit is the economic equivalent of one share of common stock, but the shares of common stock are distributed only upon termination of the Reporting Person's services as a director of the Issuer.</footnote>
