(*) For the purpose of computing the ratio of earnings to fixed charges,
    "earnings" consist of income (loss) before income taxes and extraordinary
    item plus fixed charges less capitalized interest. "Fixed charges" consist
    of interest expense including amortization of debt issuance costs, a portion
    of rent expense which is deemed to be representative of an interest factor,
    and capitalized interest. For the years ended December 31, 1990, 1991 and
    1992 earnings were insufficient to cover fixed charges by $83,070,000,
    $228,680,000 and $131,761,000 respectively. For the period ended August
    25,1994, earnings were insufficient to cover fixed charges by $201,209,000.
