(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
     and nine months ended September 30, 2001 and 2000, but were not included
     in the computation of diluted EPS because the impact was anti-dilutive.

(b)  During the three and nine months ended September 30, 2001 and 2000, the
     anti-dilutive effect associated with options and warrants 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. The total
     anti-dilutive options and warrants excluded for the quarters ended
     September 30, 2001 and 2000 were 3,803 and 9,699, respectively. Further,
     3,798 and 7,483 anti-dilutive options and warrants were excluded from the
     year-to-date September 30, 2001 and 2000 periods, respectively.
