(1)

The ratio of earnings to fixed charges was computed by dividing earnings (loss) from continuing operations before taxes and fixed charges by total fixed charges from continuing operations for the periods indicated. Fixed charges from continuing operations include (i) interest expense and capitalization and amortization of debt discount and issuance costs on all indebtedness and (ii) one-third of all rental expense, which the Company considers to be a reasonable approximation of the interest factor included in rental expense.

(2)

For the year ended October 30, 2004, earnings were inadequate to cover fixed charges. The Company needed additional earnings of $19.6 million to achieve a ratio of earnings to fixed charges of 1.0x.
