    <footnotes>
        <footnote id="F1">&quot;Share units&quot; were based on a NAV of $36.70 per share as of June 20, 2003.

Change in amount reflects &quot;change&quot; in shares due to fluctuations in market value from one valuation date to the next.  No shares were sold.

Share &quot;units&quot; are converted, for reporting and communication purposes, to &quot;shares&quot; of stock.  The number of &quot;shares&quot; reported under this Plan are based on the NAV at valuation end, divided by the share price.  However, there is also a cash component to the stock fund, which varies throughout the year.  Due to this NAV and cash variation from valuation to valuation, the number of shares will appear to change because of the accounting procedures used to valuate the Plan.
