________________________________________________________________________________
 (a) In the twelve months ended December 31, 1993 and December 31, 1991,
 earnings were inadequate to cover combined fixed charges and preferred stock
 dividends by $172 million and $36 million, respectively. In 1993, the Company
 recorded an after-tax charge of $132 million for personnel reductions, business
 restructurings involving consolidations and re-alignments within divisions,
 costs at sites of discontinued businesses, future environmental liabilities,
 and other charges. In 1991, the Company recorded an after-tax charge of $80
 million to cover losses on the disposition and write-down of certain businesses
 and costs of personnel reductions.

 (b) The ratio of earnings to combined fixed charges and preferred stock
 dividends has been computed based upon income before taxes and fixed charges
 included in income (loss) after eliminating the amortization of capitalized
 interest and the undistributed (earnings) losses of less than 50%-owned
 affiliates. Fixed charges include interest and that portion of rental expense
 deemed to represent interest.
