- ------------
    
(1) In computing the ratio of earnings to fixed charges: (a) earnings have been
    based on income from continuing operations before income taxes and fixed
    charges (exclusive of interest capitalized) and (b) fixed charges consist of
    interest and amortization of debt issuance costs (including amounts
    capitalized) and the estimated interest portion of rents.
