   *  Earnings were insufficient to cover fixed charges, preferred stock
      dividends and non-cash conversion of Series A Preferred Stock by $879.0
      million and $292.9 million in 2003 and 2001, respectively.

(A) Dividend expense is grossed up for taxes based on the Company's effective
tax rate. During 2001 and 2000, the Company's effective tax rate was 83.6% and
70.6%, respectively, which deviates from the statutory tax rate primarily due to
non-deductible portion of goodwill amortization. Effective January 1, 2002, in
accordance with SFAS 142, goodwill is no longer amortized. If goodwill
amortization had not been recorded, the ratio of earnings to fixed charges and
preferred stock dividends would have been as follows:
