SEALED AIR ANNOUNCES DEFINITIVE AGREEMENT

FOR THE SALE OF DIVERSEY JAPAN

ELMWOOD PARK, N.J., Tuesday, October 30, 2012 – Sealed Air Corporation (NYSE:SEE) announced today that it has entered into a definitive agreement with an investment vehicle of The Carlyle Group (“Carlyle”), a global alternative asset manager, for Carlyle to acquire Diversey G.K. (“Diversey Japan”) (an indirect subsidiary of Diversey, Inc.) for gross proceeds of approximately ¥30 billion (USD equivalent of approximately 377 million).

Diversey Japan is a leading provider of cleaning, sanitation and hygiene products and solutions, mainly to institutional customers in the Japanese market, with trailing twelve month sales as of September 30, 2012, of approximately $321 million.

“The determination to sell Diversey Japan follows a strategic portfolio review aimed at focusing on higher growth countries in which our portfolio offers the greatest potential,” said William V. Hickey, Sealed Air’s Chair of the Board and Chief Executive Officer. “We are very committed to our strategy of growing our presence in food safety and security, facility hygiene and product protection globally. We intend to continue our close relationship with Diversey Japan as we collaborate in areas such as product development, procurement and providing quality service to customers. The sale of Diversey Japan allows us to continue to offer leading solutions and service levels, while accelerating debt reduction and generating value for our stockholders.”

The transaction is expected to be completed in the fourth quarter of 2012, subject to the satisfaction of customary closing conditions. The price will be subject to certain purchase price adjustments. The Company noted that Diversey Japan will now be accounted for as a discontinued operation as of September 30, 2012, which is expected to impact third quarter 2012 net earnings per share by $0.03. Full third quarter results and further detail regarding the transaction will be presented on Sealed Air’s upcoming earnings call on November 2, 2012.
