(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 is determined based on an estimate of a reasonable interest factor at the inception of the leases.

(2) Due to our losses for the six months ended June 30, 2010 and the years ended December 31, 2009 and 2008, the ratio coverage was less than 1:1 for these periods. We would have had to have generated additional earnings of $61, $108, and $814 for the six months ended June 30, 2010 and the years ended December 31, 2009 and 2008, respectively, to have achieved coverage ratios of 1:1.

(3) The loss for the year ended December 31, 2008 includes the effect of an $1,147 pretax non-cash goodwill impairment charge. The effect of this charge was to reduce the ratio of earnings to fixed charges. Had this charge been excluded from the calculation, the ratio of earnings to fixed charges would have been 2.2x for the year ended December 31, 2008.
