For purposes of calculating the unaudited ratio of earnings to fixed charges,
earnings consist of income (loss) before income taxes and minority interest 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 quarter ended March 31, 2004, earnings were inadequate to cover fixed charge
requirements by $1,663. For the quarter ended March 31, 2003, earnings were
inadequate to cover fixed charge requirements by $3,513. For the six months
ended December 31, 2003, earnings were inadequate to cover fixed charge
requirements by $13,272. For the nine months ended March 31, 2003, earnings were
inadequate to cover fixed charge requirements by $18,768.
