Item 5.  Other Events and Regulation FD Disclosure.

     Crompton Corporation announced today that it has completed
the sale of its organosilicones business to General Electric
Company and its acquisition of the GE Specialty Chemicals

the transaction, Crompton received $633 million in cash for its
organosilicones business and acquired the GE Specialty Chemicals

organosilicones business sold to GE.  The earn-out will total a
minimum of $105 million and a maximum of $250 million, bringing
the full value of the transaction to a minimum of $910 million
