           ChemFirst Announces Special Shareholders' Meeting and
             Receipt of FTC Request for Additional Information
                     in Connection with Proposed Merger

JACKSON, Miss. (Sept. 3, 2002)-- ChemFirst Inc. (NYSE: CEM) announced today
that it has scheduled a special meeting of its shareholders to consider and
act on a proposal to approve ChemFirst's previously-announced merger
agreement with DuPont. The special meeting will be held on October 16,
2002, at 11:00 a.m., local time, at Dennery's, 330 Greymont Avenue,
Jackson, Mississippi. Shareholders of record at the close of business on
September 6, 2002, the record date for the special meeting, will be
entitled to vote at the meeting.

         ChemFirst also announced that the Federal Trade Commission (FTC)
has requested additional information relating to the previously announced
merger agreement between ChemFirst and DuPont. The merger has already been
approved by the German Federal Cartel Office under applicable German
antitrust laws.

         The FTC's request extends the waiting period for clearance under
the Hart-Scott-Rodino Antitrust Improvements Act of 1976 until 30 days
after ChemFirst and DuPont comply with the request unless terminated
earlier. ChemFirst and DuPont will continue to cooperate with the FTC's
review of the proposed merger and anticipate that the merger will close
during the fourth quarter of 2002.

         Completion of the merger is subject to customary closing
conditions, including approval of the merger agreement by ChemFirst
shareholders, in addition to antitrust clearance.

         This press release includes forward-looking statements based on
management assumptions and expectations. These forward-looking statements

(or non-occurrence) of transactions and events which may be subject to
circumstances beyond the control of ChemFirst and its subsidiaries, that

on risk factors that could affect actual results, please refer to the
company's 2001 Form 10-K and most recent 10-Q's.
