Introduction
o    Welcome to the call. This is Ann Gualtieri, Vice President of investor
     relations for DuPont.
o    As you know, DuPont announced yesterday that it has signed a
     definitive agreement to acquire ChemFirst. The purpose of this call is
     to briefly review the strategic rationale for this acquisition and
     provide an opportunity for clarifying questions from the investment
     community.
o    With me on the call are:

     -   Dave Miller, Vice President and General Manager of the DuPont
         Electronic Technologies business...joining us from his office in
         Research Triangle Park, North Carolina;

     -   Jeff Coe, Vice President and General Manager of the DuPont
         Chemical Solutions Enterprise, here with me.

     -   And joining us on the line from Jackson, Mississippi, are Kelly
         Williams, Chairman and CEO of ChemFirst, and Mike Summerford,
         President and Chief Operating Officer of ChemFirst

o    Let me remind you that this call is open to the media and the general
     public on a listen only mode. A separate call is scheduled for 12:45
     to respond to questions from the media.

o    Members of the investment community who are on DuPont's Email list
     have a short power point presentation attached to our notification of
     this conference call. Others on the call may access the presentation
     from DuPont's website (www.dupont.com) by clicking on the investor
     center. These slides are supplementary to my remarks.

o    During the course of this conference call, we may make forward looking
     statements. All statements that address expectations or projections
     about the future are forward looking statements. Although they reflect
     our current expectations, these statements are not guarantees of
     future performance, but involve a number of risks. We urge you to
     review both DuPont and ChemFirst SEC filings for a discussion of some
     of the factors that could cause actual results to differ materially.

Let me start with a description of ChemFirst. As you can see on slide 1,
ChemFirst comprises three operating units. ChemFirst Electronic Materials
and EKC Technologies are leading, global suppliers of products used to
manufacture semiconductor chips. Taken together, sales for these units were
$86 million last year. The third operating unit - First Chemical
Corporation -- is a major producer of polyurethane intermediates, primarily
aniline, with 2001 sales of $192 million.

DuPont will acquire ChemFirst in a cash transaction valued at $408 million,
with a ChemFirst per share value of $29.20. This represents a a 28%%
premium to yesterday's closing share price, and an 11% premium to the 6
month average share price. The acquisition is expected to be about one cent
per share dilutive in the first 12 months, due to integration costs, and
accretive thereafter

The closing of the transaction is subject to approval of ChemFirst
shareholders and regulatory approval. We expect to close in the 4Q.

Our primary objective in acquiring ChemFirst is to strengthen DuPont's
Electronic and Communications Technologies growth platform. At the same
time, we expect the excellent fit of ChemFirst's aniline business with
DuPont's Chemical Solutions Enterprise to add attractive earnings to the
equation. Slide 2 summarizes the overall strategic fit of ChemFirst.

I will first cover the fit with DuPont Electronic Technologies.
---------------------------------------------------------------

ChemFirst's strong position in the semiconductor industry will complement
DuPont's existing product portfolio and enhance our efforts to develop and
commercialize the next generation of materials for market segments that are
expected to grow at double-digit rates. In particular:

o    ChemFirst is a leading manufacturer of photoresist polymers for the
     current generation of high-end (248nm) semiconductor chips. In
     addition to being attractive in its own right, this business would
     give us access to several technologies critical to the manufacture and
     commercialization of DuPont's next-generation (193nm and 157nm)
     polymers -- which have a projected 13% CAGR.

o    ChemFirst also has a leading global position in strippers and removers
     for semiconductor fabrication, which would strengthen our access to
     and relationships with semiconductor manufacturers worldwide. Demand
     for these materials is projected to grow at 14% CAGR.

o    Finally, ChemFirst has an emerging position in slurries for chemical
     mechanical planarization (CMP), which is critical for advanced
     semiconductors. Use of CMP technology is expected to grow at a more
     than >20% CAGR, as smaller and smaller features are incorporated in
     semiconductor chips. ChemFirst's CMP technologies and products are
     complementary to those of DuPont's CMP joint venture with Air
     Products, and will be offered to the JV per our agreement with Air
     Products..

o    Slides 3 and 4 highlight ChemFirst's position in the key electronic
     materials segments that it serves.

Turning to the Chemicals side of the acquisition:

o    ChemFirst's chemicals operations focus on aniline, which DuPont also
     produces. Aniline is a key intermediate used to make monomers for
     rigid polyurethane foam, a mid-performance polymer used mainly in the
     construction, automotive, and appliance industries. Rigid
     polyurethanes are growing at approximately 2x GDP as they continue to
     replace metal and wood. ChemFirst's aniline business is quite
     profitable and a good cash generator.

o    ChemFirst also produces a family of toluene-based intermediates, which
     are also sustainably profitable cash generators.

o    By acquiring ChemFirst, DuPont will be able to realize significant
     synergies in technology, operations, and supply chains, while also
     diversifying its customer base.

To Conclude: We are excited about the growth and earnings potential
inherent in the ChemFirst acquisition. ChemFirst is an excellent fit with
two of DuPont's five growth platforms. It provides products and
technologies that complement DuPont's current and future presence in fast
growing segments within the semiconductor industry. And it's chemical
intermediates business will add attractive earnings from day one.

We will now open the line to questions.
