(a)   The deficiency in earnings required to cover fixed charges for the fiscal
      years ended March 31, 2006, 2005, 2004 and 2002 was $17,946, $27,352,
      $16,944 and $2,948, respectively. The deficiency in earnings to cover
      fixed charges is computed by subtracting earnings before fixed charges,
      income taxes and discontinued operations from fixed charges. Fixed charges
      consist of interest expense, net amortization of debt issuance expense
      (recorded as a component of interest expense in the consolidated financial
      statements), and that portion of operating lease rental expense which we
      deem to be representative of interest. The deficiency in earnings required
      to cover fixed charges includes depreciation of property, plant and
      equipment and amortization of goodwill and other assets and non-cash
      charges which are reflected in cost of sales, selling, general and
      administrative expenses and other expense, in the following amounts (in
      thousands):
