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 and six months ended December 31, 2002, earnings were inadequate
to cover fixed charge requirements by $13,322 and $15,255, respectively. For
the three months and six months ended December 31, 2001, earnings were
inadequate to cover fixed charge requirements by $2,063 and $18,656,
respectively.
