Ratio of earnings to fixed charges (2)                   9.8            7.2           -              -             9.3          5.6


(1)  A 1/3 factor was used to compute the portion of rental expenses deemed representative of the interest factor.

(2)  The results of operations for the twelve months ended December 31, 2001 are adequate to cover fixed charges as defined.
     However, the ratio is negatively affected by the REDUX and PONDIMIN diet drug litigation charge of $950,000 taken in the third
     quarter of 2001. Excluding the additional charge for the REDUX and PONDIMIN diet drug litigation, the pro forma ratio of
     earnings to fixed charges would be 9.4 for the twelve months ended December 31, 2001.

     The results of operations for the year ended December 31, 2000 are inadequate to cover total fixed charges as defined. The
     coverage deficiency for the year ended December 31, 2000 is $324,887. Excluding the charge for the REDUX and PONDIMIN diet
     drug litigation of $7,500,000, the gain on sale of Immunex common stock of $2,061,204 and the Warner-Lambert Company
     termination fee of $1,709,380, the pro forma ratio of earnings to fixed charges would be 8.9 for the year ended December 31,
     2000.

     The results of operations for the year ended December 31, 1999 are inadequate to cover total fixed charges as defined. The
     coverage deficiency for the year ended December 31, 1999 is $403,694. Excluding the charge for the REDUX and PONDIMIN diet
     drug litigation of $4,750,000, the pro forma ratio of earnings to fixed charges would be 8.1 for the year ended December 31,
     1999.

(3)  Amounts have been restated to reflect the Cyanamid Agricultural Products business as a discontinued operation.
