For the purposes of computing the ratio of earnings to fixed charges, earnings consist of income (loss) from continuing operations before income taxes plus fixed charges. Fixed charges consist of interest expense, amortization of debt issuance costs and that portion of rental expense we estimate to be representative of interest. Earnings, as defined, were not sufficient to cover fixed charges by $189,160 for the fiscal year ended March 31, 2002 and $17,694 for the fiscal year ended March 31, 2003.

        The following computation of pro forma ratio of earnings to fixed charges for the nine months ended December 31, 2003 reflects the use of a portion of the proceeds of the issuance of our ³/4% Convertible Senior Notes to repurchase approximately $124.2 million of our 3% Convertible Subordinated Notes, as if the repurchase occurred at the beginning of the period. No pro forma ratio of earnings to fixed charges has been presented for the year ended March 31, 2003 due to the deficiency of earnings to cover fixed charges.
