Item 1.01.  Entry Into a Material Definitive Agreement.

On March 11, 2005,  Monsanto  Company ("the Company")  entered into a $1 billion
364-day  revolving  credit  agreement (the "Revolving  Credit  Agreement")  with
certain lender parties  thereto,  JPMorgan Chase Bank,  N.A., as  administrative
agent,  Citibank,  N.A., as syndication  agent,  ABN AMRO Bank N.V., The Bank of
Tokyo-Mistubishi,   Ltd.,   Chicago  Branch  and  Bank  of  America,   N.A.,  as
co-documentation  agents,  and J.P. Morgan  Securities Inc. and Citigroup Global
Markets Inc., as joint lead arrangers and joint bookrunners.

Under the terms of the Revolving  Credit  Agreement,  the Company may obtain and
utilize from time to time up to $1 billion in revolving credit loans for general
corporate  purposes.  Borrowings  under  the  Revolving  Credit  Agreement  bear
interest at one of two rates as described  in the  Revolving  Credit  Agreement.
There is a  facility  fee  payable  to each  lender,  which  shall  accrue at an
applicable  percentage per annum as described in the Revolving Credit Agreement.
There  is also a  utilization  fee.  The  Revolving  Credit  Agreement  contains
affirmative,  negative and financial  covenants  customary for such  financings,
including,  among other things, limits on the incurrence of debt, the incurrence
of liens,  and mergers and  consolidations.  The Revolving Credit Agreement also
contains customary  representations  and warranties.  Breaches of the covenants,
representations  or warranties may be grounds for  termination.  Other events of
default include the Company's  failure to pay certain debt, the  acceleration of
certain debt, certain insolvency,  bankruptcy or ERISA events,  unpaid judgments
over a specified  amount,  or a change in control as specified in the  Revolving
Credit Agreement. The covenants, representations, warranties and other events of
default are  identical to those in the  Company's  existing $1 billon  five-year
revolving  credit  agreement,  dated as of June 4, 2004.  The  Revolving  Credit
Agreement expires on March 10, 2006.

A copy of the Revolving Credit Agreement is filed as Exhibit 10.15 hereto and is
incorporated  by reference  herein.  The  description  of the  Revolving  Credit
Agreement  above is  qualified  in its entirety by reference to the full text of
the Revolving Credit Agreement.
