---------------
(1) The ratio of earnings to fixed charges represents the historical ratio of
    the Company and is calculated on a total enterprise basis. The ratio is
    computed by dividing the sum of earnings before provision for taxes and
    fixed charges (excluding capitalized interest) by fixed charges. Fixed
    charges represent interest (including capitalized interest) and amortization
    of debt discount and expense and the interest factor of all rentals,
    consisting of an appropriate interest factor on operating leases.
