(a)  The $345.0 million of Convertible Debentures which are convertible into 8.7
     million shares at $39.60 per share were outstanding during the three months
     ended March 31, 2001 and 2000, but were not included in the computation of
     diluted EPS because the impact was anti-dilutive.

(b)  During the three months ended March 31, 2001 and 2000, the antidilutive
     effect associated with 1.6 million and 6.1 million options, respectively,
     as well as 2.3 million and 2.5 million warrants, respectively, were
     excluded from the computation of diluted earnings per share, since the
     exercise price of these options and warrants was greater than the average
     market price of the Company's common stock during these periods.
