Dow Reichhold To Shut Down Operations

Research Triangle Park, N.C.-based Dow Reichhold Specialty Latex LLC — a joint venture between The
Dow Chemical Co., Midland, Mich., and Research Triangle Park-based Reichhold Inc. — will sell
certain business assets and close all manufacturing facilities, and plans to end all business
activities before the end of 2008.

The Dow Chemical Co. plans to buy back the businesses it originally supplied when the joint
venture was established, and will provide future service directly to respective customers. The
transaction is expected to be completed by September 18.

Dow Reichhold will shut down its headquarters in Research Triangle Park; a manufacturing
plant in Cheswold, Del.; the Asia/Pacific offices in Malaysia; and an office and laboratory in
Shanghai. The company also is pursuing the sale of other business assets originally provided by
Reichhold.
