      Stock options to purchase 75,529,995 shares and 23,695,194 shares were
outstanding as of March 31, 2001 and 2000, respectively, but were not included
in the computation of diluted earnings per share because the options' exercise
price was greater than the average market price of the common shares and,
therefore, the effect would have been antidilutive. In addition, 2,642,542
restricted stock units in the first quarter of 2000 relating to the company's
Long Term Performance Plan were not included in the computation of diluted
earnings per share as their effect would have been antidilutive. Net income
applicable to common shareholders excludes preferred stock dividends of $5
million for the three months ended March 31, 2001 and 2000.
