DuPont To Expand North Carolina Plant

Wilmington, Del.-based DuPont will invest approximately $55 million to expand its manufacturing
facility in Kinston, N.C. During the next three years, the company will spend $24 million and will
create 66 jobs at the plant, which will produce corn-derived DuPont™ Sorona® polymer.

In addition, DuPont has received a $200,000 grant from the One North Carolina Fund, which
provides financial assistance to qualified businesses through the state’s Commerce Finance Center.

“Kinston is special to the DuPont Bio-Based Materials business because it is where we
discovered the recipe for making DuPont Sorona … ,” said John Ranieri, vice president and general
manager, DuPont. “I am proud and honored to say that we are now taking this proprietary technology
from concept to commercial-scale reality with the expansion of our operations in Lenoir County.”&
