-------
(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. For the six months ended June 30, 2001,
    amount includes a gain of $28 million that resulted from an
    insurance settlement.
