                                                  =====          ====


(1)  One-third of rental expense is considered to be the amount
     representing return on capital.
     
(2)  Earnings are income before income taxes and fixed charges.  Since
     the Single Business Tax (the Tax) and rental expense have already
     been deducted, the Tax and the one-third portion of rental
     expense considered to be fixed charges are added back.
     
(3)  The results for the first six months of 1995 reflect a $72.8
     million pretax credit primarily from settlement gains resulting
     from lump sum pension payments from the pension plan to former
     employees who left the business in the nonmanagement work force
     restructuring.
