Exhibit 12.2

RATIO OF EARNINGS TO

COMBINED FIXED CHARGES AND PREFERRED STOCK DIVIDENDS

The following table sets forth our ratio of earnings to combined fixed charges and preferred stock dividends on a reported basis for the periods indicated. Earnings consist of income (loss) from continuing operations plus fixed charges. Fixed charges consist of interest expense and amortization of deferred financing costs. We have calculated the ratio of earnings to combined fixed charges and preferred stock dividends by adding net income (loss) from continuing operations to fixed charges and dividing that sum by such fixed charges plus preferred dividends, irrespective of whether or not such dividends were actually paid.
