      Crompton Corporation ("Crompton") has entered into a definitive agreement

it is acquiring from Crompton. The earn-out, which is based on incremental
contribution margin, will be a minimum of $105 million and a maximum of $250
million payable quarterly over a three-year period. The transaction is subject
