Statements Regarding Computations of Ratios of Earnings to Fixed Charges

The following table sets forth the ratio of earnings to fixed charges for our company for each of the periods indicated. We calculated the ratio of earnings to
fixed charges by dividing earnings by total fixed charges. Earnings are defined as income from continuing operations before provision for income taxes plus Fixed Charges. Fixed charges are defined as
the sum of interest expenses plus amortized capitalized expenses related to indebtedness plus an estimate of the interest within rental expense.
