Ratio of earnings to fixed charges (1)                                                      4.3

      For the purpose of computing this ratio, "earnings" consist of (a) income
      from continuing operations before income taxes (adjusted for undistributed
      earnings or recognized losses of partially-owned affiliates, minority
      interest in earnings or losses of consolidated subsidiaries, and
      amortization of previously capitalized interest),  plus (b) fixed charges,
      minus (c) interest capitalized during the period.  "Fixed charges" consist
      of (a) interest incurred and amortization of debt expense plus (b) the
      portion of rent expense representative of the interest factor.

(1) Included in earnings is a $54.6 million pre-tax net gain on sale of
    businesses, as disclosed in Note 3 to the Company's consolidated financial
    statements. Excluding this gain, the ratio of earnings to fixed charges
    would be 4.0.
