(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 agricultural products business as a discontinued
    operation.

(4) The income from continuing operations before federal and foreign taxes for the three
    months ended March 31, 2000 included the Warner-Lambert termination fee of $1,709.4.
    Excluding the termination fee, the ratio of earnings to fixed charges would be 9.6 for
    the three months ended March 31, 2000.
