Note 1: For purposes of calculating the ratio of earnings to fixed
        charges, "earnings" consist of earnings from continuing
        operations before income taxes, adjusted for the portion of fixed
        charges deducted from such earnings.  "Fixed charges" consist of
        interest on all indebtedness (including capital lease obligations
        and capitalized interest), amortization of debt expense and the
        percentage of rental expense on operating leases deemed
        representative of the interest factor.
Note 2: The ratios of earnings to fixed charges, before the restructuring
        and special charges, for 1995 and 1994 were 1.9 to 1 and 2.4 to
        1, respectively.
Note 3: The above computations do not include any fixed charges related
        to the Company's guarantee of debt for Calspan SRL Corporation.
        The debt guarantee was $18.0 million at December 29, 1996 and
        $21.7 million at December 31, 1995.
