          This Amendment (this "Amendment") is Amendment Number 3 to the
Tender Offer Statement on Schedule TO initially filed on June 12, 2002 (as
amended on July 3, 2002 and July 15, 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 6 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 and July 15, 2002.

ITEM 4. TERMS OF THE TRANSACTION; ITEM. 6. PURPOSE OF THE TRANSACTION AND
PLANS AND PROPOSAL; ITEM 8. INTEREST IN SECURITIES OF THE SUBJECT COMPANY

          Item 4, Item 6, Item 8 are hereby amended by adding thereto the
following:

          The initial offering period in respect of the Offer expired at
6:00 p.m., New York time, on Friday, July 19, 2002. Based upon information
provided by The Bank of New York, the depositary for the Offer (the
"Depositary"), a total of 17,959,400 Shares were tendered during the
initial offering period and not properly withdrawn. Conoco Canada has
accepted all such Shares for payment.

          Conoco Canada has commenced a subsequent offering period with
respect to the Offer, which expires at 6:00 p.m. New York time on July 30,
2002 (the "Subsequent Offering Period Expiration Date"), unless extended.
During the subsequent offering period, Conoco Canada will immediately accept
for payment and promptly pay for Shares as they are tendered. Shareholders of
Gulf Indonesia who tender their Shares during the subsequent offering period
will receive the same U.S.$13.25 per Share cash consideration paid to
shareholders who tendered during the initial offering period.

          Shareholders who tender their Shares during the subsequent offering
period may withdraw those Shares at any time prior to the Subsequent Offering
Period Expiration Date. Withdrawals will only be effective if the withdrawing
shareholder delivers to the Depositary, concurrently with its notice of
withdrawal, a certified check in the name of Conoco Canada in an amount equal
to the aggregate Offer price in respect of the withdrawn Shares and otherwise
follows the procedures for withdrawal set forth in Conoco Canada's Notice of
Subsequent Offering Period, which is attached hereto as Exhibit (a)(1)(N) and
incorporated herein by reference. Shareholders who tendered Shares during the
initial offering period may no longer withdraw those Shares.
