(1) The ratio of earnings to fixed charges has been computed by dividing earnings by fixed charges. For purposes of computing he ratio:

earnings consist of (a) income from continuing operations before income from equity investments in partnerships and income taxes, (b) fixed charges and (c) cash distributions from partnership investments; and

fixed charges consists of (a) interest on debt, (b) amortization of debt issuance costs and (c) one-third of operating rental expense, which management believes is representative of the interest component of rent expense.

(2) Due to our losses in the three months ended March 31, 2006 and the year ended December 31, 2003, the ratio was less than 1:1 for these periods. We would have had to generate additional earnings of $115,674 and $80,292 to achieve a ratio of earnings to fixed charges of 1:1 for the three months ended March 31, 2006 and the year ended December 31, 2003, respectively.
