ITEM 2.01   Completion of Acquisition or Disposition of Assets

     On  March  23,  2005,   Monsanto   Company   ("Monsanto"),   completed  the
previously-announced  acquisition  of  Seminis,  Inc.,  a  Delaware  corporation
("Seminis"), through the merger of Monsanto Sub, Inc., a wholly owned subsidiary
of Monsanto ("Merger Sub"), with and into Seminis (the "Merger"). The Merger was
effected  pursuant to that  certain  Agreement  and Plan of Merger,  dated as of
January 22, 2005,  by and among  Monsanto,  Merger Sub, and Seminis (the "Merger
Agreement"). Seminis continues as the surviving corporation of the Merger and as
a wholly owned subsidiary of Monsanto.

     Prior to the  consummation  of the Merger,  Seminis  was a  privately  held
corporation  based in Oxnard,  California.  Seminis is a producer of  commercial
fruit and vegetable seeds.

     The aggregate  consideration paid by Monsanto in connection with the Merger
consisted of  approximately  $1.4 billion in cash and assumed  debt,  subject to
Marinet Investments, LLC's ("Marinet") contingent value right described below.

     Prior to closing,  on March 11, 2005,  Marinet,  a holder of  co-investment
rights in Seminis which were  terminated  upon the  consummation  of the Merger,
elected pursuant to the Merger  Agreement to reduce the merger  consideration it
would  otherwise  have been entitled to receive by $50 million in exchange for a
performance  based contingent value right to receive up to $125 million based on
the  achievement of certain net sales targets over the  thirty-six  month period
ending September 30, 2007.

     Upon the  consummation  of the  Merger,  each  outstanding  share of common
stock,  par value  $.01 per share,  of  Seminis  ("Seminis  Common  Stock")  was
converted  into the right to receive  an amount in cash  equal to  $10.52.  Such
shares of Seminis  Common Stock were held by  affiliates of Fox Paine & Company,
LLC, which  collectively held 74.6% of the outstanding  shares of Seminis Common
Stock, various employees of Seminis and other stockholders.

     The foregoing description of the Merger does not purport to be complete and
is qualified in its  entirety by  reference to the Merger  Agreement,  a copy of
which was  previously  filed with the  Securities  and  Exchange  Commission  by
Monsanto as Exhibit  2.1 to the  Current  Report on Form 8-K on January 27, 2005
and is incorporated in this Item 2.01 by reference.

     On  March  23,  2005,  Monsanto  issued  a  press  release  announcing  the
completion of the Merger.  The press release is attached  herewith as Exhibit 99
to this  Current  Report  on Form  8-K and  incorporated  in this  Item  2.01 by
reference.
