-------
(1) The ratio of earnings to fixed charges for the periods before
    September 1, 1997 was not calculated. Historical computation of
    earnings to fixed charges is not considered meaningful before
    that date because Solutia was not an independent company and
    Monsanto Company did not allocate debt to Solutia.

(2) Includes restructuring and other unusual items of $122 million
    for the year ended December 31, 2000, $61 million for the year
    ended December 31, 1999, and $72 million for the four months
    ended December 31, 1997. For the nine months ended
    September 30, 2001, amount includes a gain of $28 million that
    resulted from an insurance settlement.
