       NOTE:  THIS NEWS RELEASE IS BEING RE-ISSUED TO CORRECT INACCURATE
   INFORMATION REGARDING THE FINAL PRORATION FACTOR AND THE NUMBER OF SHARES
           OF DUPONT COMMON STOCK REQUESTED BY PIONEER SHAREHOLDERS


              DUPONT ANNOUNCES FINAL PRORATION FACTOR FOR MERGER
                   WITH PIONEER HI-BRED INTERNATIONAL, INC.
              --------------------------------------------------


        WILMINGTON, Del., Oct. 7 -- DuPont today announced a final proration
factor of 86.00449855 percent in connection with its merger with Pioneer
Hi-Bred International, Inc.  Pioneer shareholders will receive for each
Pioneer share for which a stock election was made a prorated distribution of
DuPont common shares equal to the final proration factor multiplied by the
previously announced conversion ratio of .6561.

        Under the terms of the merger agreement, Pioneer shareholders had
certain rights to elect to receive cash, DuPont shares or some combination of
cash and DuPont shares in exchange for their Pioneer shares.  The agreement
further provided that in the aggregate, 45 percent of the Pioneer shares would
receive cash and 55 percent of the shares would receive DuPont common stock.

        Consistent with the 45/55 split, 68,612,134.8 shares of DuPont common
stock are being distributed to Pioneer shareholders in connection with the
merger.  Pioneer shareholders filed election forms requesting a total of
79,777,378 shares of DuPont common stock.  Because election forms submitted by
Pioneer shareholders requested payment in DuPont common stock in excess of
55 percent in the aggregate, requests for stock will be prorated as described
above.  Pioneer shareholders electing to receive DuPont common stock will






                                       2






receive $40 in cash per share for each Pioneer share requested to be converted
to DuPont common stock but not converted due to proration.  Pioneer share-
holders electing cash will not be prorated and will receive $40 in cash per
share.

        The total value of the transaction is approximately $7.7 billion for
the 80 percent of Pioneer not currently owned by DuPont.

        DuPont is a science company, delivering science-based solutions that
make a difference in people's lives in food and nutrition; health care;
apparel; home and construction; electronics; and transportation.  Founded in
1802, the company operates in 65 countries and has 92,000 employees.
