MIDDLEBURY, Conn. -- Chemtura Corporation (the "Company") (NYSE: CEM) today announced that it has called for redemption all of its outstanding $158,938,000 aggregate principal amount of 9 7/8% Senior Notes due 2012 (CUSIP No. 227116AE0) (the "Notes"). The Notes will be redeemed at a redemption price of approximately 112.777% (the "Estimated Redemption Price") of the principal amount thereof plus accrued interest up to, but excluding, the redemption date of July 3, 2006 (the "Redemption Date"). The Estimated Redemption Price is based on a current reference treasury yield of 5.05% plus 0.50%.
