(A)   The preferred stock dividend requirements of consolidated subsidiaries is
      included in fixed charges (i.e., the denominator of the ratio calculation)
      but excluded from the numerator of the ratio calculation because such
      amount was not deducted in arriving at the pre-tax income (loss) from
      continuing operations, as defined.

(B)   Due to the Company's losses in 1998 and 1999, the ratio coverage was less
      than 1:1. The Company would have had to generate additional earnings of
      approximately $19.0 million and $14.7 million in 1998 and 1999,
      respectively, to achieve a coverage ratio of 1:1.

(C)   Included in earnings for 1998 and 1999 were special charges of $10.2
      million and $5.2 million, respectively, relating to asset impairments and
      litigation settlement costs. If such charges were not taken the Company
      would have needed to generate additional earnings of $8.8 million and $9.5
      in 1998 and 1999, respectively, to achieve a coverage of 1:1.
