(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
     six months ended June 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 six months ended June 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
     June 30, 2001 and 2000 were 3,937 and 7,610, respectively. Further,
     3,931 and 7,265 anti-dilutive options and warrants were excluded
     from the year-to-date June 30, 2001 and 2000 periods, respectively.
