(a) Ratio includes the effect of the Loss from Zimmer Plant Disallowance of $144,533,000 (net of applicable
income taxes  of $14,534,000).  As a result, earnings for  the twelve  months ended  December 31, 1993 were
inadequate to cover fixed charges by $21,744,000.  If the effect of the Loss from Zimmer Plant Disallowance
were excluded, the ratio would be 2.46 for the twelve months ended December 31, 1993.
