CHEMFIRST INC. (LOGO)


DATE:    August 30, 2002

TO:      Employee Stock Purchase Plan Participants

FROM:    Bill Kemp


As previously announced, ChemFirst on July 23, 2002 entered into a merger
agreement with E. I. du Pont de Nemours and Company providing for the
acquisition of ChemFirst by DuPont at a price of $29.20 per share of
ChemFirst common stock. The proposed merger is subject to a number of
conditions, including approval of the merger agreement by ChemFirst
shareholders, and is expected to be completed in the fourth quarter of
2002. Under the merger agreement, ChemFirst was required to amend the
ChemFirst Inc. 1997 Employee Stock Purchase Plan (the "Plan" or the "ESPP")
to address various transitional matters relating to the merger. A copy of
the amendment to the Plan is attached for your information. As a
participant in, or owner of shares acquired under, the Plan, you should be
aware of the following:


1.   Participants who enrolled in the Plan for the current offering period
     (July 1, 2002 through September 30, 2002) may not increase their
     contribution rates under the Plan from those in effect on July 23,
     2002. No new participants may join the Plan during the current
     offering period.

2.   There will be no further offering periods under the Plan.

3.   The amendment to the Plan provides, among other things, that each
     participant's outstanding right to purchase ChemFirst common stock
     under the ESPP will terminate immediately prior to the merger in
     exchange for a specified cash payment. However, the merger is not
     expected to take place prior to the end of the current offering period
     on September 30, 2002, and, prior to the merger, there will be no
     further offering periods in which new rights to acquire shares under
     the ESPP would arise. As a consequence, ChemFirst anticipates that all
     rights to purchase ChemFirst common stock under the ESPP will have
     been exercised by the end of the current offering period, and there
     should be no such rights outstanding and subject to termination
     immediately prior to the merger.

4.   Upon completion of the merger, you will be entitled to receive $29.20
     in cash, without interest, in exchange for each share of ChemFirst
     common stock that you hold in your ESPP account with EquiServe, less
     any applicable transaction and commission fees charged by EquiServe.
     Any such shares that you purchased under the ESPP during an offering
     period commencing fewer than two years prior to the completion of the
     merger will be treated under the Plan as having been sold in a
     "disqualifying disposition." As a result, you would recognize ordinary
     income equal to the difference between those shares' fair market value
     on the date of purchase and your purchase price. ChemFirst would be
     required to report the amount of ordinary income recognized upon such
     a disqualifying disposition on your W-2 form for the year in which the
     merger is completed.

5.   The Plan will terminate on the effective date of the merger.

Until the merger has occurred, you may access your ESPP account with
EquiServe and process sales via:

     o   Telephone Voice Response System (1-800-633-9394): available 24
         hours a day/7 days a week.

     o   Customer Service Representatives-available each trading day 8:30
         a.m.-6:00 p.m. Eastern time.

     o   www.equiserve.com

EquiServe is available to assist you with the following account issues:

     o   Account share balance inquiries, transfer instructions, and market
         price history

     o   Duplicate participant statement and 1099 forms

     o   Redeeming ESPP shares, which may be sold any day the stock market
         is open. If your sale request is received by EquiServe no later
         than 1:00 p.m. Eastern time on a trading day, your shares will be
         sold that day. Requests logged after hours or after the 1:00 p.m.
         cutoff will be processed on the next trading day.

If you have any questions about the Plan in the coming weeks, please
contact your local human resources representative.

                             FIRST AMENDMENT TO
            THE CHEMFIRST INC. 1997 EMPLOYEE STOCK PURCHASE PLAN

         WHEREAS, ChemFirst Inc. (the "Company") maintains the ChemFirst
Inc. 1997 Employee Stock Purchase Plan (the "Plan"); and

         WHEREAS, the Company has proposed to enter into a certain
Agreement and Plan of Merger (the "Merger Agreement") among the Company, E.
I. du Pont de Nemours and Company, a Delaware corporation ("Parent"), and
Purple Acquisition Corporation, a Mississippi corporation and wholly owned
subsidiary of Parent ("Merger Sub"), pursuant to which Merger Sub will be
merged with and into the Company, at which time (the "Effective Time") the
separate corporate existence of Merger Sub shall cease and the Company
shall continue as the surviving corporation and a wholly owned subsidiary
of Parent; and

         WHEREAS, the Merger Agreement provides, among other things, that
the Company shall amend the Plan effective as of the date of the Merger
Agreement (the "Merger Agreement Date") to provide that (i) participants in
the Plan may not increase their payroll deductions or purchase elections
from those in effect as of the Merger Agreement Date, (ii) no offering
periods shall be commenced under the Plan after the Merger Agreement Date,
(iii) each participant's outstanding right to purchase the Company common
stock under the Plan shall terminate immediately before the Effective Time
in exchange for a cash payment in an amount equal to the difference between
the merger consideration and the applicable option price, and (iv) the Plan
shall terminate at the Effective Time; and

         WHEREAS, the Board of Directors of the Company has adopted and
approved the execution of an amendment to the Plan in the form set forth
below.

         NOW, THEREFORE, the Plan is amended by adding a new Section 5.18
immediately following Section 5.17 to read in its entirety as follows,
effective as of the Merger Agreement Date:

                  "5.18 Effect of Merger. On July 23, 2002, the Sponsoring
         Employer entered into that certain Agreement and Plan of Merger
         (the "Merger Agreement") among the Sponsoring Employer, E. I. du
         Pont de Nemours and Company, a Delaware corporation ("Parent"),
         and Purple Acquisition Corporation, a Mississippi corporation and

         Employer shall continue as the surviving corporation and a wholly

         the Merger Agreement, and notwithstanding any provision of the
         Plan to the contrary: (i) a Member may not increase his Member's
         Contribution Rate from his Member's Contribution Rate in effect as
         of July 23, 2002, (ii) no Offering Period shall commence after
         July 23, 2002, (iii) each Option granted under the Plan and
         outstanding with respect to a Member immediately before the
         Effective Time shall terminate immediately before the Effective
         Time in exchange for a cash payment from the Sponsoring Employer
         to the Member equal to the excess, if any, of (A) the product of
         (1) the number of shares of Common Stock that could have been
         purchased with the contributions held in the Member's Contribution
         Account immediately before the Effective Time (the "Applicable
         Shares") at the Issue Price (treating the date on which the
         Effective Time occurs as the last day in the Offering Period for
         purposes of determining the Issue Price) and (2) the Merger
         Consideration (as defined in the Merger Agreement), over (B) the
