(a)  The $345,000,000 of 5.0% Convertible Subordinated Notes due 2007 which are
     convertible into 8,712,121 shares at $39.60 per share were outstanding
     during the three and nine months ended September 30, 2000 and 1999, but
     were not included in the computation of diluted EPS because the impact was
     anti-dilutive.

(b)  Options and warrants to purchase shares of common stock were excluded from
     the computation of diluted earnings per share in those cases where the
     exercise price was greater than the average market price of common shares.
