        <footnote id="F1">Transactions in Issuer's 401(K)Plan, Executive Savings Investment Plan, and Deferred Compensation Plan are made through the acquisition or disposition of units rather than actual shares.  The value of units are re-valued rather than based upon earnings or losses and appreciation or depreciation on the underlying investments, and adjustments for contributions to, transfers to and from, and distributions from the applicable investment fund.</footnote>
