        <footnote id="F1">The deferred stock units acquired on the first of the month are the total result of compensation payable for committee and/or Board meeting(s) attendance in the prior month in the form of stock, also as a result of an outside director's quarterly retainer fee payable on the first day of the quarter in the form of stock, all based on the closing price of the issuer's stock on the first day of the current month.  The deferred stock units do not have any conversion or exercise price (Box 2), nor do they have an exercisable or expiration date (Box 6) for this transaction.</footnote>
