STATEMENT OF COMPUTATION OF

RATIO OF EARNINGS TO FIXED CHARGES

For purposes of computing the ratio of earnings to fixed charges, “earnings” consist of (a) income (loss) from continuing operations before income taxes , (b) amortization of capitalized interest and (c) fixed charges, exclusive of capitalized interest cost. “Fixed charges” consist of (a) interest incurred, (b) amortization of deferred loan costs and debt discount and (c) that portion of operating lease rental expense (33%) deemed to be representative of interest. You should read the ratio of earnings to fixed charges in conjunction with our consolidated and condensed financial statements that are incorporated by reference in this prospectus.
