Exhibit 12

COMPUTATION OF RATIO OF EARNINGS TO FIXED CHARGES

     Set forth below is information concerning our ratio of earnings to fixed charges on a consolidated basis for the periods indicated. This ratio shows the extent to which our business generates enough earnings after the payment of all expenses other than interest to make the required interest payments on the notes.

     The ratio of earnings to fixed charges in computed by dividing earnings before fixed charges by fixed charges. Earnings before fixed charges consist of earnings (loss) before income tax, minority interest and equity in unconsolidated subsidiaries, plus fixed charges. Fixed charges consist of interest expense, amortization of debt issuance costs and the portion of rental expense that we believe is representative of the interest component of lease expense. For the year ended August 31, 2002, there was a deficiency of earnings to fixed charges of $47.2 million.
