Company is Focused on Delivering Results Through Growth and Productivity

WILMINGTON, Del., May 9, 2007 - At a conference with security analysts today, DuPont Executive Vice President & Chief Financial Officer Jeffrey L. Keefer reviewed DuPont’s growth strategies and recent results achieved against those strategies.

“Our rising return on innovation and rapid growth in emerging markets are key growth drivers for us,” Keefer said. Recent new products from DuPont include: Herculex® insect-protected seed corn; Tyvek® Thermawrap™ and DuPont™ Energain® to reduce building energy consumption; and, new aesthetics for Corian® surfaces. New products to be introduced in the near future include DuPont™ Optimum™ GAT™ which is expected to be in the market for soybeans in 2009 and corn in 2010. In addition, the company remains intensely focused on advancing its high-potential bio-based fuels and bio-based materials pipelines.

“While driving innovation, we also continue to improve our cost and capital productivity on a project-by-project basis,” said Keefer. “Our financial progress from 2003 through 2006 demonstrates the track we are on:

• Pre-tax operating income margin has increased six percentage points,
• return on invested capital has increased seven percentage points,
• and, average growth in earnings per share over this three-year period has been 20 percent.”

“We will continue to execute our growth strategies while maintaining financial discipline and returning cash to our shareholders,” Keefer said. He highlighted the company’s commitment to returning cash to shareholders through dividends and share repurchases. In particular, Keefer commented that DuPont's $5 billion share repurchase program launched in November 2005 is nearly 80 percent complete.
