Notes:

      (1)   In December 1997, the company adopted Statement of Financial
            Accounting Standards No. 128, "Earnings Per Share". Under this
            standard, basic earnings per share is computed by dividing net
            income applicable to common stockholders by the average number of
            common shares outstanding during the year. The computation of
            diluted earnings per share assumes that the average number of common
            shares outstanding is increased by dilutive common share equivalents
            and the conversion of securities having a dilutive effect, and that
            net income applicable to common stock is increased by dividends and
            after-tax interest on such securities.

      (2)   Potentially dilutive securities at December 31, 1997 included shares
            issuable pursuant to certain stock-based compensation. These
            securities included 450,000 shares issuable upon the vesting of the
            restricted share units issued in 1996 as well as 270,000 shares
            issuable upon the exercise of stock options calculated using the
            treasury stock method. Potentially dilutive securities in 1997 were
            not included in the computation of diluted earnings per share
            because the effect would have been antidilutive.
