We reported a loss from continuing operations before provision for income taxes and minority interest for the years ended December 31, 2000 and December 31, 2001 and we would have needed to generate additional income from operations before provision for income taxes and minority interest of $23,291 and $28,111, respectively to cover our fixed charges of $154,975 and $177,032, respectively.

        The ratios of earnings to fixed charges presented above were computed by dividing our earnings by fixed charges. For this purpose, earnings have been calculated by adding fixed charges to income (loss) from continuing operations before provision for income taxes and minority interest. Fixed charges consist of interest costs, the interest component of rental expense and amortization of debt discounts and deferred financing costs and premiums.
