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 evaluate the financial results of the company. These measures should not be viewed as an alternative to GAAP measures of performance. Furthermore, these measures may not be consistent with similar measures provided by other companies.

This data should be read in conjunction with the previously published company reports on Form 10-K, 10-Q and 8-K. These reports along with reconciliations of non-GAAP measures to GAAP results are available on the Investor Center website at www.dupont.com.

Forward Looking StatementsDuring 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 “plans,” “expects,” “will,” "believes," “intends,” and “estimates.” Although they reflect our current expectations, these statements are not guarantees of future performance, but involve a number of risks, uncertainties, and assumptions. Some of those risk factors include: fluctuations in energy and raw material prices; failure to develop and market new products and optimally manage product life cycles; global economic and capital markets conditions; litigation and environmental matters; changes in laws and regulations or political conditions; and business or supply disruptions. The Company does not undertake to update any forward-looking statements as a result of future developments or new information.

Developing MarketsTotal developing markets is comprised of Developing Asia, Developing Europe, Middle East & Africa, and Latin America. A detailed list of all developing countries is available on the Earnings News Release link on the Investor Center website at www.dupont.com.
