MONSANTO CHIEF EXECUTIVE OFFICER  ANNOUNCES CHANGES TO ORGANIZATIONAL  STRUCTURE
AND MANAGEMENT TEAM

     ST.  LOUIS (June 18,  2003) - Hugh  Grant,  president  and chief  executive
officer  of  Monsanto  Company  (NYSE:  MON),  today  announced  changes  to the
company's  organizational  structure and the related management team. Grant said
the new  structure  is designed to create  focus and  accountability  around his
three near-term objectives: (1) Providing sustainable, efficient cash generation
from Monsanto's chemistry businesses;  (2) Optimizing income growth of the seeds
and traits businesses; and (3) Renewing the focus on biotechnology acceptance.

     "As we continue the process of transforming  Monsanto from a business based
on chemistry  to an  agricultural  global  leader  focused  largely on seeds and
traits,  it's imperative that our business  structure  reflects the realities of
how our business is changing,"  Grant said. Grant reiterated that he expects the
gross profit  generated from the company's  seeds and traits business to surpass
that generated by its Roundup herbicide franchise for the first time in 2003.

     In order to optimize the cost  structure as the company's  business  models
are  redefined,  Grant  said the  commercial  accountability  for the  company's
business will be focused under two geographic leaders.

     Effective  immediately,  Brett D. Begemann and Carl M. Casale will lead all
of  Monsanto's  commercial  operations  in  their  respective  geographies.   As
International  Commercial Lead, Begemann will be responsible for redesigning the
company's business models in specific countries to optimize the  cash-generating
capabilities  of the  chemistry  business and the growth  potential of seeds and
traits.

Casale will lead Monsanto's North and Central  American  businesses with a focus
on  executing  the  post-patent  strategy  for Roundup  herbicide  in the United
States,  and  driving  growth  in  the  seeds,  traits  and  animal  agriculture
businesses.  Both Begemann and Casale have been elected by  Monsanto's  board of
directors as executive vice presidents of the company.

     "I believe  this  management  team and  structure  will help us advance the
market and technology  leadership  edge we have built,  while  positioning us to
take even greater advantage of the opportunities that will unfold as we continue
our transformation, " Grant said.

     The board also  elected  Gerald A.  Steiner and Mark J. Leidy as  executive
vice  presidents  of Monsanto.  In the new post of Commercial  Acceptance  Lead,
Steiner will redefine the company's biotechnology  acceptance goals and strategy
to improve Monsanto's global market acceptance for biotechnology and support the
product  pipeline.   Leidy  will  continue  to  lead  the  global  manufacturing
organization,  with a focus on producing  quality  products while leveraging the
company's manufacturing cost position.

     Cheryl P. Morley was elected by the board as a senior vice president of the
company. She will work with Grant to develop the company's  longer-term strategy
in her new role.

     In addition, Terrell K. Crews, executive vice president and chief financial
officer,  will take on additional  operational  duties.  Grant said the roles of
other members of Monsanto's  executive  management  team will remain  unchanged,
including:   Robert  T.  Fraley,  Ph.D.,  executive  vice  president  and  chief
technology officer; Charles W. Burson,  executive vice president,  secretary and
general counsel; and John M. Murabito, senior vice president, human resources.

     "I have  confidence  that this  management  team will act with  urgency  to
organize their  respective teams and complete the  transformation  of Monsanto,"
Grant said. "The team fully understands our objectives,  including the near-term
objective of delivering on our 2003 earnings commitments."
