(1)   For purposes of computing the ratio of earnings to fixed charges, earnings consist of income (loss) before income tax expense plus fixed charges. Fixed charges consist of interest expense, amortization of deferred financing fees and a portion of rental expense that management believes is representative of the interest component of rental expense. For the year ended December 31, 2008, fixed charges exceeded earnings by $107.0 million.
