Agreement will help DDC to meet EPA 2007 emissions control regulations.

CORNING, N.Y., – Corning Incorporated (NYSE:GLW) announced today that it has entered into a long-term agreement with Detroit Diesel Corporation for the supply of advanced diesel emissions control products. This multi-year agreement will help Detroit Diesel, a subsidiary of DaimlerChrysler AG, meet Environmental Protection Agency (EPA) 2007 regulations which went into effect Jan. 1, 2007.

Corning and Detroit Diesel worked jointly to integrate Corning DuraTrap® filters and Corning Celcor® substrates into Detroit Diesel’s emissions control systems for medium- and heavy-duty engines which will be used in EPA 2007 compliant on-highway applications.

“We are pleased that Detroit Diesel has selected Corning as its supplier of advanced emissions control products” said Thomas R. Hinman, senior vice president and general manager of Corning Diesel Technologies. “Our innovation and manufacturing leadership, including materials and process inventions, have enabled Corning to continually advance our filter and substrate solutions to meet the needs of leading vehicle and engine manufacturers. This agreement further strengthens our relationship with Detroit Diesel and continues to reinforce our position as a leader in the heavy-duty diesel market.”

Corning is a leading supplier of advanced cellular ceramic substrates and diesel particulate filters to all of the world’s major manufacturers of gasoline and diesel engines and vehicles. The company invented an economical, high-performance cellular ceramic substrate in the early 1970s that is now the standard for catalytic converters worldwide. In 1978, Corning developed the cellular ceramic particulate filter to remove soot from diesel emissions.

Since 2001, Corning has announced investments totaling $365 million for its diesel manufacturing facility in the Corning, N.Y. area which is designed to make the large filter and substrate products that are used in diesel engine exhaust treatment systems. The facility began production in 2004.
