     The ratios of earnings to fixed charges were computed by dividing earnings
by fixed charges. For this purpose, earnings include income before income taxes
and fixed charges. Fixed charges include interest and amortization of debt
expenses, and the estimated interest component of rentals. Certain amounts for
prior years have been restated to conform to the current presentation.
 
     During the five years ended December 31, 1996, there were no shares of
preferred stock outstanding. Accordingly, the ratio of earnings to combined
fixed charges and preferred stock dividends for each of the five years is the
same as the ratio of earnings to fixed charges.
