(1) Ratio of earnings to fixed charges means the ratio of net income (before
fixed charges and income taxes) to fixed charges, where fixed charges are
the aggregate of interest expense, the portion of interest expense under
operating leases deemed by us to be representative of the interest factor
and amortization of debt issuance costs.
(2) Due to net losses incurred in the quarter ended March 31, 2004 and the
years ended December 31, 2000, 2001, 2002, 2003 and 2004, the ratio of
earnings to fixed charges in those periods was less than 1:1. We would have
had to generate additional earnings in the amounts indicated in the table
to have achieved a ratio of 1:1.
