MONSANTO COMPANY INCREASES FIRST-QUARTER EARNINGS PER SHARE GUIDANCE
Company Reconfirms Full-Year 2006 Free Cash Flow and Earnings Guidance

       ST. LOUIS (Dec. 5, 2005) - Monsanto Company (NYSE: MON) announced today
that it is increasing its first-quarter 2006 earnings per share (EPS) guidance.

       Monsanto now expects that 20 cents per share of its full-year EPS on both
a reported and ongoing basis will occur in the first quarter. The company
revised its first-quarter EPS guidance upward from its earlier estimate for the
quarter of approximately 10 cents per share.

       "While our first quarter historically has been a smaller part of our
overall fiscal year, we believe we are off to a good start," said Hugh Grant,
chairman, president and chief executive officer of Monsanto. "Early indications
from our seeds and traits business suggest continued growth in the upcoming
season, and this growth will be a key contributor to our leadership position in
the years ahead."

       Stronger-than-expected results for cotton traits in Australia and for
Roundup herbicides in Europe and the United States, in part related to earlier
timing of demand particularly in Europe, are the key reasons driving the
improvement in the quarter.

       In addition, Monsanto said that early order patterns for its corn seed
and traits business indicate another strong season ahead for its U.S. business.

       Monsanto now believes that U.S. acres planted with its Roundup Ready and
YieldGard Rootworm insect-protected corn trait technologies could be
approximately 15 percent higher collectively than the company's previous
estimate of a total of 38 million acres for both traits. The company noted that
potential gains from its seeds and traits business could be partially offset by
higher raw material costs from suppliers given the effect from the 2005
hurricane season.

       "We continue to monitor the effect of changes in petroleum-based products
and natural gas prices on our raw materials," said Terry Crews, chief financial
officer of Monsanto. "Our full-year guidance anticipates that our suppliers will
pass on a portion of their higher raw material costs to us."

       Monsanto now expects that its full-year 2006 EPS guidance will be toward
the upper end of its previously announced range of $2.35 to $2.50, on a reported
and ongoing basis. The company confirmed




       that its guidance for free cash flow in fiscal year 2006 remains the same
in the range of $825 million to $900 million. (For a reconciliation of free cash
flow, see note 1.)

       Monsanto's Brett Begemann, executive vice president and international
commercial lead, will discuss the earnings guidance as part of his presentation
at the Citigroup Investment Research 16th Annual Chemical Conference in New
York. Begemann will address investors at 8 a.m. (EST) on Wednesday, Dec. 7, as
part of the conference.

presentation will be available through the Citigroup Investment Research
conference Web site. To access the webcast of this presentation, go to:

                  RECONCILIATION OF NON-GAAP FINANCIAL MEASURE

Free Cash Flow: The presentation of free cash flow is not intended to replace
net income (loss), cash flows, financial position or comprehensive income
(loss), and is not a measure of financial performance as determined in
accordance with generally accepted accounting principles (GAAP) in the United
States. The following table reconciles free cash flow to the respective most
directly comparable financial measure calculated in accordance with GAAP.

1.   Reconciliation of Free Cash Flow: Free cash flow represents the total of
     cash flows from operations and investing activities. With respect to the
     projected free cash flow guidance provided under the caption "Fiscal Year
     2006 Target," Monsanto does not include any estimates or projections of Net
     Cash Provided (Required) by Financing Activities because in order to
     prepare any such estimate or projection, Monsanto would need to rely on
     market factors and conditions that are outside of its control.
