Business Editors

CORNING, N.Y.--(BUSINESS WIRE)--Oct. 17, 2001

Corning Incorporated (NYSE:GLW), a leading supplier of diesel substrates and particulate filters, announced today that its board of directors has approved the construction of a new diesel emission control product manufacturing facility.

The new plant, to be located in Erwin, NY, will use advanced manufacturing technologies and processes to produce both diesel filters and diesel catalyst substrates. Construction is scheduled to begin by early 2002, with initial production of substrate and filter products expected in early 2004.

"As global demand increases for stricter regulation of emissions, Corning is committed to helping diesel vehicle manufacturers meet these tighter standards," said Corning's President and CEO, John Loose. "The worldwide market for substrates and filters for diesel applications is expected to reach approximately $1.5 billion by 2008. With initiatives such as our new plant announced today, Corning expects to continue on as a leading supplier in this market."

"We are preparing to fill the diesel industry's future needs by anticipating tomorrow's requirements today," added Steve Suttle, Corning Environmental Technologies vice president. "Coupled with our extensive diesel emissions product design, modeling and testing capabilities, this new plant will enable Corning's customers to meet the strong and growing demand for clean-diesel vehicles."

Having received board approval, the company plans to invest approximately $200 million in the new plant over a five-year period beginning this year.

Demand for diesel emission-control products continues to increase as stricter air quality control regulations are implemented. These regulations include U.S. legislation scheduled for implementation in 2004 and 2007, as well as European standards set for 2005 and anticipated for 2008.
