DuPont today said it has been notified of an unsolicited mini-tender offer by Ontario-based TRC Capital Corporation (TRC), a private Canadian investment company.  DuPont is not affiliated with TRC, the offer or offer documentation.

On Nov. 9, TRC issued an Offer to Purchase up to 2,000,000 outstanding shares of common stock of E. I. du Pont de Nemours and Company for $41.50 per share.  The offer was more than 3 percent lower than the closing price of the DuPont stock on Nov. 8, 2005.

DuPont does not recommend or endorse this offer and urges its shareholders to obtain current market quotations for their shares of Common Stock, consult with their broker or financial advisor and exercise caution with respect to TRC's offer.

TRC has made many such mini-tender offers for other companies' shares.  Mini-tender offers are third-party offers to purchase less than 5 percent of a company's outstanding shares, thereby avoiding many filing, disclosure and procedural requirements of the U.S. Securities and Exchange Commission (SEC).

DuPont recommends that its shareholders review SEC's "Investor Tips" regarding mini-tender offers.  According to the Commission, "Some bidders make mini-tender offers at below market prices, hoping that they will catch investors off guard if the investors do not compare the offer price to the current market price" and that "mini-tender offers typically do not provide the same disclosure and procedural protections that larger, traditional tender offers provide."  Investor Tips and additional information from the SEC can be found at http://www.sec.gov/investor/pubs/minitend.htm.
