DuPont reported financial results for 4Q 2008 and full year 2008. Net sales decreased 17% in 4Q due to a 20% decline in volume, though pricing increased 7%. For the full year, net sales rose 4% while volume declined 5% and pricing increased 7%. Earnings per share were negative $0.70 in 4Q and $2.20 for the full year. All business segments experienced sales declines in 4Q, with Performance Materials down 30% and Coatings & Color Technologies down 21%. DuPont expects continued challenges in 2009 from weak global economic conditions and has initiatives to reduce costs, capital spending, and working capital to enhance earnings and cash flow.

The attached charts include company information that does not conform to generally accepted accounting
principles (GAAP). Management believes that an analysis of this data is meaningful to investors because it
provides insight with respect to ongoing operating results of the company and allows investors to better

Forward Looking Statements
During the course of this presentation we may make forward-looking statements or provide forward-looking
information. All statements that address expectations or projections about the future are forward-looking
statements. Some of these statements include words such as quot;expects,quot; quot;anticipates,” quot;plans,quot; quot;intends,quot;

guarantees of future performance, but involve a number of risks, uncertainties, and assumptions. Some of
those risk factors include economic conditions, competitive pressures, challenges associated with research
and development, market acceptance of new products, and regulatory approval. We urge you to review
DuPont's SEC filings, particularly its latest annual report on Form 10-K and quarterly report on Form 10-Q,
for a discussion of some of the factors which could cause actual results to differ materially.
The Company does not undertake to update any forward-looking statements as a result of future
