_________________

(1) Fixed charges consist of interest expense, which includes amortization of deferred finance charges, interest expense-subordinated debentures, capitalized interest and imputed interest on our lease obligations. The interest component of rent was determined based on an estimate of a reasonable interest factor at the inception of the leases.

(2) Due to our losses for the years ended December 31, 2010 and 2009, the ratio coverage was less than 1:1 for these years. We would have had to have generated additional earnings of $63 and $108 for the years ended December 31, 2010 and 2009, respectively, to have achieved coverage ratios of 1:1.
