(1)      There was a deficiency of earnings to fixed charges for the three
         months ended July 3, 1999 of $1,132.

         -    The ratios of earnings to fixed charges were computed by dividing
              earnings by fixed charges. For this purpose, "earnings" consist of
              earnings before taxes and extraordinary item plus fixed charges
              and "fixed charges" consist of interest expense and amortization
              of debt issuance costs.
