For the purposes of determining the ratio of earnings to fixed charges, earnings consist of earnings (loss) before income tax expense (benefit), and minority interest income (loss). Fixed charges consist of interest expense which includes capitalized interest and amortization of capitalized interest, amortization of debt issuance costs and that portion of rent expense attributable to interest costs. Due to the loss before provision for income taxes and cumulative effect of changes in accounting principles for the six months ended June 30, 2004, the ratio coverage was less than 1:1. In order to achieve a coverage of 1:1, the Company would have had to generate additional income of approximately $1.4 million for the six months ended June 30, 2004.
