ITEM 1.01.        ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

         On Aug. 1, 2005, Monsanto Company's People and Compensation Committee
approved the Monsanto Company Fiscal Year 2006 Annual Incentive Plan (the "2006
Plan"). The 2006 Plan covers the performance period September 1, 2005 through
August 31, 2006. Eligibility includes regular employees who do not participate
in a local sales or manufacturing annual incentive plan. Funding of the 2006
Plan is determined by the Company's attainment of certain financial goals
related to sales growth (10% weighting), earnings per share (50% weighting) and
cash flow (40% weighting) and the determination by the People and Compensation
Committee that such attainment satisfies certain subjective performance criteria
as determined by the Committee. Various performance levels are approved by the
People and Compensation Committee with a payout level (as a percentage of target
annual incentive opportunity) associated with each level of performance as
follows: (i) threshold, 35%, (ii) budget, 100%, and (iii) outstanding, 200%. The
incentive pool will be funded at no less than 20% of budget level funding in the
event the Company pays dividends with respect to each of its financial quarters
ending during the performance period.

         A summary of the 2006 Plan can be found in Exhibit 10 filed herewith
and is incorporated herein by reference.
