       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 are considered common stock equivalents but
were not included in the per share calculation for the quarter ended
March 31, 1996, as their inclusion would have had an antidilutive effect.

     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 are considered common stock equivalents but were not included in the
per share calculation for the quarter ended March 31, 1996 as their inclusion
would have had an antidilutive effect.  The 5% convertible subordinated
debentures are not considered common stock equivalents and were not included in
the fully diluted earnings per share calculation 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 period presented.
