<FN>
Stock options exercised in conjunction with cancellation of repurchased common stock caused a significant change
in the shares  outstanding used in computing  earnings per share between quarters.  Due to this change in shares
outstanding, the sum of quarterly earnings per share does not equal year-to-date earnings per share.
