NEW YORK, May 16, 2007 – At a briefing today with security analysts, Diane H. Gulyas , group vice president – DuPont Performance Materials , discussed the segment’s growth
and productivity strategies. With more than $6 billion in annual sales, the DuPont Performance Materials growth platform is a leading example of customer-driven innovation and value-added
applications development for the global automotive, packaging and electrical markets.

“Performance Materials has delivered solid year-over-year improvement and growth by launching innovative new products and market-focused solutions, while driving productivity,” said
Gulyas. “Productivity improvement has been especially important in light of the significant increase in raw material costs over the past three years. In addition, we are accelerating
growth in emerging markets by leveraging our capabilities and global customer base.”

The Performance Materials segment believes it will grow revenues and profits at compound annual growth rates over time of 6 and 10 percent, respectively.

“Our key to success is our ability to provide customers with more productive, higher performance polymer materials and system solutions that positively impact their profitability,”
said Gulyas. “New applications and products that serve the needs of valuable customers in attractive end-use markets and geographies will continue to advance our global growth.”
