TO:         E. I. du Pont de Nemours and Company ("EID")

AND TO:  DuPont Canada Inc. ("DuPont Canada")

     The undersigned option holder holds options to purchase class A common
shares, series 1 of DuPont Canada under the DuPont Canada Employee Stock Option
Plan.

     DCI Acquisition Inc. (the "Purchaser"), a subsidiary of EID, has made an
offer (the "Offer") to purchase all of the outstanding class A common shares,
series 1 of DuPont Canada, not already owned by the Purchaser and its
affiliates. The Offer does not extend to DuPont Canada options. In a letter
dated April 17, 2003 (the "Option Exchange Letter"), EID, subject to obtaining
all necessary regulatory and other approvals, offered to issue me options to
acquire shares of common stock of EID if I surrender all of my DuPont Canada
options which are unexercised (whether vested or unvested and whether "in the
money" or not) (the "Unexercised Options") as at the Effective Date (as defined
below).

     I accept the offer contained in the Option Exchange Letter with respect to
my Unexercised Options and, conditional upon the Purchaser taking up the shares
deposited under the Offer, surrender all of my Unexercised Options to DuPont
Canada for cancellation in exchange for the issuance by EID to me of options to
purchase shares of common stock of EID. The EID options will be issued in
accordance with the terms and conditions set forth in the Option Exchange
Letter. I understand that the surrender of my Unexercised Options and the
issuance of EID options will be effective on the last date that the Purchaser
takes up shares under the Offer (the "Effective Date").

     I understand that if the Purchaser does not take up the shares deposited
under the Offer, my surrender will not take effect and I will continue to hold
my Unexercised Options.


                    PAGE TWO OF DUPONT OPTION ELECTION FORM

     I acknowledge that by completing and returning this Election Form, all of
my Unexercised Options as of the Effective Date will be surrendered and my
existing option certificates will be cancelled, subject to the terms and
conditions of the Option Exchange Letter.
