- ----------

(1)   For purposes of calculating the ratio of earnings to fixed charges,
      earnings represent income before income taxes, discontinued operations,
      cumulative effect of change in accounting principle charges and fixed
      charges. Fixed charges represent interest expense and a portion of rental
      expense which we believe is representative of the interest component of
      rental expense.

(2)   Earnings were insufficient to cover fixed charges in the period December 1
      to December 31, 2004, and each of the years ended December 31, 2003 and
      2002 by $6.0 million, $11.0 million, and $21.7 million, respectively.
