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.
<FN>
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 $22.9 million at September 29, 1995 and $20.7
        million at December 31, 1995.
