Ratio of Earnings to Fixed Charges*                    1.4x            1.4x           1.5x            **              **



------------------
*    For the purpose of computing the ratio of earnings to fixed charges,
     earnings consist of income (loss) before provision for income taxes
     and before adjustment for loss from equity investments plus fixed
     charges. Fixed charges consist of interest charges, amortization of
     debt expense and discount or premium related to indebtedness, whether
     expensed or capitalized, and that portion of rental expense we believe
     to be representative of interest.

**   Due to Fisher's loss in 1998 and 1997, the ratio coverage was less
     than 1:1. Fisher must generate additional earnings of $60.3 million in
     1998 and $5.1 million in 1997 to achieve a coverage ratio of 1:1.
