For purposes of calculating the unaudited ratio of earnings to fixed charges,
earnings consist of income (loss) before provision for income taxes plus fixed
charges. Fixed charges consist of interest charges and amortization of debt
issuance costs, whether expensed or capitalized, the portion of rental expense
that is representative of interest, and preferred share accretion. For the
three months ended March 31, 2002, earnings were inadequate to cover fixed
charge requirements by $6,427. For the nine months ended March 31, 2002,
earnings were inadequate to cover fixed charge requirements by $25,083. For
the three months ended March 31, 2001, earnings were inadequate to cover fixed
charge requirements by $855. For the nine months ended March 31, 2001, earnings
were inadequate to cover fixed charge requirements by $6,772.
