Fixed charges are equal to interest expense plus one-third of operating rental expense which management believes is representative of the interest component of rent expense.

(2) Earnings were insufficient to cover fixed charges for the years ended December 31, 2000, 2001 and 2002 by $33.5 million, $31.2 million and $207.6 million, respectively.
