Dow AgroSciences LLC and Monsanto Company today announced a global, multi-year, toll manufacturing agreement that also licenses Dow AgroSciences the rights to Monsanto's glyphosate herbicide registration data. The agreement will allow Dow AgroSciences to register its own brand of glyphosate herbicide for sale globally. However, Dow AgroSciences will not be able to reference Monsanto data when registering its products for use in Japan.

Additionally, the agreement allows Dow AgroSciences to use its own brand of glyphosate
herbicide over the top of Roundup Ready soybeans and cotton in the year 2000 in the United
States, and beginning in 2001, over the top of Roundup Ready corn in the United States.

The agreement does not include lawn and garden uses.

Monsanto's Roundup and Roundup Ultra herbicides, which include the active ingredient
glyphosate, and Dow AgroSciences glyphosate brand(s) will compete with each other in the
agricultural marketplace.
