(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 $403,694. 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.

     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.
