(1)      The ratio of earnings to fixed charges has been computed by dividing
         earnings by fixed charges. For purposes of computing the 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 consist 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 year ended December 31, 2003, the ratio was
         less than 1:1 for this period. We would have had to generate additional
         earnings of $80,292 to achieve a coverage ratio of 1:1 for the year
         ended December 31, 2003.
