|(1) | For purposes of computing the ratio of earnings
    available to cover fixed charges, earnings consist of income
    before taxes plus fixed charges. Fixed charges consist of
    interest on indebtedness including amortization of deferred
    financing fees and fixed loan guarantee fees. No ratio is
    presented for the fiscal year ended October 30, 2004 as the
    earnings for that period were $3,960,000 less than the fixed
    charges.
