*   Earnings were insufficient to cover fixed charges, preferred stock
    dividends and non-cash conversion of Series A Preferred Stock by $879.0
    million, $292.9 million and $315.6 million in 2003, 2001 and 1999,
    respectively.

**  Earnings were insufficient to cover fixed charges by $290.0 million in 1999.

(A) Dividend expense is grossed up for taxes based on the Company's effective
tax rate. During 2001, 2000 and 1999, the Company's effective tax rate was
83.6%, 70.6% and 8.8%, 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:
