Ratio of Earnings to Fixed Charges                        19.7          13.0 (a)     16.8 (b)      21.5        19.3       14.3

(a)  Excluding an $87.7 million ($64.5 million,  net of tax)  restructuring  and
     related  inventory charge in 2001, the company's ratio of earnings to fixed
     charges would have been 16.2 times.

(b)  Excluding a $41.3 million ($29.7 million,  net of tax) restructuring charge
     in 2000,  the company's  ratio of earnings to fixed charges would have been
     18.5 times.


In the computation of the company's ratio of earnings to fixed charges, earnings
consist of earnings before income taxes,  plus fixed charges,  less  capitalized
interest,  plus amortization of capitalized  interest.  Fixed charges consist of
interest expense  excluding the benefit of capitalized  interest and including a
reasonable approximation of the interest component included in rental expense.
