(1)   For the twelve months ended November 30, 2001, historical earnings from
      continuing operations before provision for income taxes, which included
      approximately $11.6 million of restructuring plus additional non-recurring
      items included in the cost of sales and selling, general and
      administrative expense captions were insufficient to cover fixed charges
      by approximately $23 million. Excluding the restructuring charge, income
      as adjusted would have been $6.8 million and the ratio of earnings to
      fixed charges would have been .37.

(2)   1999 earnings from continuing operations before provision for income taxes
      includes a non-cash writedown of systems development costs of $11,195.
      Excluding this charge, income as adjusted would have been $34,974 and the
      ratio of earnings to fixed charges would have been 1.65.

(a)   Represents one-third of rent expense which management believes represents
      a reasonable approximation of the interest component of rent expense.
