      Primary earnings per share is based on weighted average shares of
common stock outstanding plus dilutive common equivalent shares. The 5 1/4%
zero coupon convertible subordinated debentures (issued in July 1994) are
considered common stock equivalents but were not included in the per share
calculation for 1995 or 1994 as their inclusion would have had an
antidilutive effect. Shares issuable upon an assumed conversion of the 5 1/4%
zero coupon convertible subordinated debentures were dilutive for the last
three quarters of 1996. Consequently, a total of 9.2 million shares are
included in the weighted average common and dilutive common equivalent shares
for the year ended December 31, 1996.

      Fully diluted earnings per share is based on weighted average shares of
common stock outstanding plus dilutive common equivalent shares and dilutive
convertible securities. The 5 1/4% zero coupon convertible subordinated
debentures (issued in July 1994) are considered common stock equivalents but
were not included in the per share calculation for 1995 or 1994 as their
inclusion would have had an antidilutive effect. Shares issuable upon an
assumed conversion of the 5 1/4% zero coupon convertible subordinated
debentures were dilutive for the last three quarters of 1996.  Consequently,
a total of 9.2 million shares are included in the weighted average common and
dilutive common equivalent shares for the year ended December 31, 1996.  The
5% convertible subordinated debentures are not considered common stock
equivalents and were not included in the fully diluted earnings per share
calculation for 1996 as their inclusion would have had an antidilutive
effect. Fully diluted earnings per share is not presented on the face of the
Consolidated Statement of Income since dilution is less than 3% for each year
presented.
