<FN>
--------------
(1)     We have not calculated the ratio of earnings to fixed charges for the periods before September 1, 1997.
        Historical computation of earnings to fixed charges is not considered meaningful before that date
        because we were not an independent company and Monsanto Company did not allocate debt to us.

(2)     Includes restructuring and other unusual items of $122 million for the year ended December 31, 2000, $63
        million for the year ended December 31, 1999, and $72 million for the four months ended December 31,
        1997.
