ITEM 5. OTHER EVENTS.

     On May 29, 2003,  Monsanto  Company  announced  that Hugh Grant was elected
President,  Chief  Executive  Officer,  and  director  of the  board,  effective
immediately,  and that an audio  webcast  would be held on May 30, 2003, at 8:00
a.m. central (9:00 a.m. eastern),  to introduce Mr. Grant as President and Chief
Executive Officer. In addition,  we also reconfirmed our full year 2003 earnings
per share  ("EPS") and free cash flow guidance and our  second-quarter  2003 EPS
guidance.

     The audio webcast may be accessed under the "Investors Information" page on
our website located at http://www.monsanto.com  and a replay of the webcast will
be available on our website for two weeks.  A press  release dated May 29, 2003,
issued by Monsanto  Company in  connection  with Mr.  Grant's  election  and the
reconfirming  of  guidance,  is  attached  to this  report as  Exhibit  99.1 and
incorporated herein by reference.

     In connection with and as a result of Mr. Grant's election as President and
Chief  Executive  Officer,  our board  approved  amendments to the July 13, 2000
consulting agreement between the Company and Frank V. AtLee III, as amended by a
letter agreement dated February 19, 2003, to provide that:

>>   The term of the consulting agreement be extended through the earlier of the
     date of the 2004 annual meeting of  shareowners or Mr. AtLee's  termination
     of service as Chairman of the Board of Directors.
>>   His  consulting  services  to the  Company no longer  include  services  as
     interim Chief Executive Officer and President.
>>   For consulting  services  rendered to the Company from May 30, 2003 through
     the date of the expiration of the amended agreement,  his compensation will
     be $400,000 on an annualized basis, less the cash value of all regular fees
     for his services as a member of the Board,  such amounts payable in arrears
     as of the last day of each calendar month during the extended term.
>>   All deferred consulting fees earned under the consulting  agreement be paid
     to him as soon as practicable.
>>   He will  continue to be  reimbursed  for  reasonable  expenses  incurred in
     connection with his rendering of consulting services to the Company.

     Certain  statements  contained  in the  attached  press  release,  such  as
statements  concerning our  anticipated  financial  results,  current and future
product  performance,   regulatory  approvals,  currency  impact,  business  and
financial plans and other non-historical facts are "forward-looking statements."
These  statements  are based on current  expectations  and  currently  available
information.  However,  since these statements are based on factors that involve
risks  and  uncertainties,   our  actual  performance  and  results  may  differ
materially from those described or implied by such  forward-looking  statements.
Factors  that could  cause or  contribute  to such  differences  include,  among
others: fluctuations in exchange rates and other developments related to foreign
currencies  and economies;  increased  generic and branded  competition  for our
Roundup herbicide;  the accuracy of our estimates and projections,  for example,
those with respect to product returns and grower use of our products and related
distribution  inventory levels;  the effect of weather  conditions and commodity
markets on the agriculture business; the success of our research and development
activities  and the speed  with  which  regulatory  authorizations  and  product
launches  may be  achieved;  domestic and foreign  social,  legal and  political
developments,  especially  those  relating to  agricultural  products  developed
through biotechnology;  our ability to continue to manage our costs; our ability
to successfully  market new and existing  products in new and existing  domestic
and international  markets;  our ability to obtain payment for the products that
we sell;  our ability to achieve and maintain  protection  for our  intellectual
property;  the  effects of our  accounting  policies  and  changes in  generally
accepted accounting  principles;  our exposure to lawsuits and other liabilities
and  contingencies,  including those related to intellectual  property,  product
liability,   regulatory  compliance  (including  seed  quality),   environmental
contamination and antitrust; our ability to fund our short-term financing needs;
general economic and business  conditions;  and other risks and factors detailed
in our  filings  with the SEC.  Undue  reliance  should  not be  placed on these
forward-looking  statements,  which  are  current  only  as of the  date of this
report.   We   disclaim   any  current   intention   to  revise  or  update  any

                                       2


forward-looking statements or any of the factors that may affect actual results,
whether as a result of new information, future events or otherwise.
