Ratio of earnings to fixed charges (2) (4)               16.3             -            9.3           5.6           5.0           4.0


(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 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 $403,328. Excluding the charge for the REDUX and PONDIMIN
      litigation settlement 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.

(4)   The income from continuing operations before federal and foreign taxes for the nine months ended September 30, 2000 included
      the Warner-Lambert Company termination fee of $1,709,380. Excluding the termination fee, the ratio of earnings to fixed
      charges would be 10.1 for the nine months ended September 30, 2000.
