          This Amendment (this "Amendment") is the final amendment to the Tender
Offer Statement on Schedule TO initially filed on June 12, 2002 (as amended on
July 3, 2002, July 15, 2002 and July 22, 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"),
relating to the offer by Conoco Canada to purchase all the outstanding common
shares, par value U.S.$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"). This Amendment also
constitutes Amendment Number 7 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, July 3, 2002, July 15, 2002 and

tendered during the subsequent offering period and not properly withdrawn. The
