          This Amendment (this "Amendment") amends the Tender Offer Statement
on Schedule TO initially filed on June 12, 2002 by Conoco Inc., a Delaware
corporation ("Conoco"), Conoco Canada Resources Limited, a Nova Scotia
corporation and a wholly-owned subsidiary of Conoco ("Conoco Canada"), and
Gulf Indonesia Resources Limited, a New Brunswick corporation ("Gulf
Indonesia"), as amended on July 3, 2002, relating to the offer by Conoco
Canada to purchase all the outstanding common shares, par value $0.01 per
share (the "Shares"), of Gulf Indonesia not owned by Conoco Canada, at a
purchase price of U.S.$13.25 per Share, net to the seller in cash, without
interest thereon (the "Offer"). The Offer is subject to the terms and
conditions set forth in the Offer to Purchase dated June 12, 2002, as amended
on July 3, 2002 (the "Offer to Purchase"), and the related Letter of
Transmittal. This Amendment also constitutes Amendment Number 5 to the
Schedule 13D of Conoco and Conoco Canada filed with the Securities and
Exchange Commission on July 26, 2001, as amended on May 28, 2002, June 10,
2002, June 12, 2002 and July 3, 2002.

Item 13. Information Required by Schedule 13E-3

          (a) The information set forth under "SPECIAL FACTORS - Fairness of
the Offer - The Independent Committee" in the Offer to Purchase is hereby
supplemented and amended by adding the following as a bullet point:

          "o   The Valuation of RBC and the valuation procedures performed by
               RBC in connection with the Valuation, including, without
               limitation, the net asset value and precedent transaction
               analyses performed by RBC."

          (b) The information set forth under "SPECIAL FACTORS - Position of
Conoco and Conoco Canada Regarding Fairness of the Offer" is hereby
supplemented and amended as follows:

          The first paragraph is amended by adding the following as a bullet
point:

          "o   The valuation procedures performed by RBC in connection with
               the Valuation, including, without limitation, the net asset
               value and precedent transaction analyses performed by RBC."

          The second paragraph is amended and restated to read as follows:

               "Conoco and Conoco Canada did not consider the liquidation of
          Gulf Indonesia's assets to be a viable course of action based on
          Conoco's desire to retain its shareholding in Gulf Indonesia.
          Therefore, no appraisal of liquidation value was taken into account
          in the above analysis. In addition, in making their determination as
          to fairness, Conoco and Conoco Canada did not take into account the
          condition to the Offer that it be accepted by a majority of Gulf
          Indonesia shareholders not affiliated with Conoco Canada, as this
          condition is not a financial metric relevant to the financial
          evaluation of the Offer."

         After due inquiry and to the best of my knowledge and belief, I
certify that the information set forth in this statement is true, complete and
correct.
