                          AMENDMENT dated as of November 30, 2000 (this
                  "Amendment") in respect of the LONG-TERM REVOLVING CREDIT
                  AGREEMENT dated as of February 25, 1998, as amended and
                  restated pursuant to the Amendment and Restatement Agreement
                  dated as of February 23, 1999 and the Second Amendment and
                  Restatement Agreement dated as of March 31, 2000, (the "Credit
                  Agreement"), among BURLINGTON RESOURCES, INC., a Delaware
                  corporation (the "Borrower"), the financial institutions (the
                  "Lenders") listed on the signature pages thereof, Citibank,
                  N.A., as syndication agent for the Lenders, Chase Bank of
                  Texas, N.A. ("Chase" and, in its capacity as administrative
                  agent for the Lenders, the "Administrative Agent"), The Chase
                  Manhattan Bank, as auction administrative agent for the
                  Lenders (in such capacity, the "Auction Administrative
                  Agent"), and Bank of America, N.A. and Fleet National Bank, as
                  co-documentation agents for the Lenders.

         The Borrower has advised the Lenders that it desires to amend the
Credit Agreement to (i) conform the affirmative maintenance of existence
covenant to certain of its other material agreements and the existing merger
covenant by permitting conversions of Material Subsidiaries (such term and each
other capitalized term used and not otherwise defined herein having the meaning
assigned to it in the Credit Agreement as amended hereby) into non-corporate
forms and (ii) update the references to certain outdated tax forms, and has
requested in connection therewith that the Credit Agreement be amended as set
forth in Section 1 below. The parties hereto are willing so to amend the Credit
Agreement.

         In consideration of the premises and the agreements, provisions and
covenants herein contained, the parties hereto hereby agree, on the terms and
subject to the conditions set forth herein, as follows:

         SECTION 1. Amendment. Upon the effectiveness of this Amendment as
provided in Section 3 below, the Credit Agreement shall be amended as follows:

                  (i) Paragraph (a) of Section 5.01 of the Credit Agreement is
         hereby deleted in its entirety and replaced with the following:

                           "(a) PRESERVATION OF CORPORATE EXISTENCE, ETC.
                  Preserve and maintain, and cause each Material Subsidiary to
                  preserve and maintain, its existence, rights (organizational
                  and statutory) and material franchises, except as otherwise
                  contemplated or permitted by Section 5.02(c) or 5.02(d);
                  provided, that any Material Subsidiary may change its form of
                  organization to a partnership or other form of Business
                  Entity."
<PAGE>   2
                  (ii) Section 2.15 of the Credit Agreement is hereby amended by
         replacing (a) each reference to "form 1001" in such Section with the
         words "form W-8BEN" and (b) each reference to "form 4224" in such
         Section with the words "form W-8ECI".

         SECTION 2. Representations and Warranties. The Borrower represents and
warrants as of the effective date of this Amendment to each of the Lenders that:

                  (a) Immediately before and immediately after giving effect to
         this Amendment, the representation and warranties set forth in the
         Credit Agreement are true and correct in all material respects with the
         same effect as if made on the effective date hereof, except to the
         extent such representations and warranties expressly relate to an
         earlier date.

                  (b) Immediately before and immediately after giving effect to
         this Amendment, no Event of Default or Default has occurred and is
         continuing.

         SECTION 3. Conditions of Effectiveness. This Amendment shall become
effective as of the date hereof when Chase shall have received counterparts of
this Amendment that, when taken together, bear the signatures of the Borrower,
the Administrative Agent, Chase and the Majority Lenders.

         SECTION 4. Agreement. Except as specifically stated herein, the
provisions of the Credit Agreement are and shall remain in full force and
effect. As used therein, the terms "Credit Agreement", "herein", "hereunder",
"hereinafter", "hereto", "hereof" and words of similar import shall, unless the
context otherwise requires, refer to the Credit Agreement as amended hereby.

         SECTION 5. APPLICABLE LAW. THIS AMENDMENT SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE SATE OF NEW YORK.

         SECTION 6. Counterparts. This Amendment may be executed in two or more
counterparts, each of which shall constitute an original but all of which when
taken together shall constitute but one contract.

         SECTION 7. Expenses. The Borrower agrees to reimburse the
Administrative Agent for all out-of-pocket expenses incurred by it in connection
with this Amendment, including the reasonable fees, charges and disbursements of
Cravath, Swaine & Moore, counsel for the Administrative Agent.

October 18, 2000

Mr. Steven J. Shapiro
11730 Flintwood Drive
Houston, Texas 77024

Dear Steve,

As you know, the Board of Directors of Burlington Resources Inc. (the "Company")
will consider, at its meeting on October 18, 2000, your election to the position
of Senior Vice President and Chief Financial Officer for the Company. The
purpose of this letter is to confirm one issue that we have discussed relating
to your employment. Assuming that the Board does elect you to that position, if
(i) you are still employed by the Company on your 55th birthday or (ii) before
your 55th birthday, your employment is involuntarily terminated by the Company
(other than for "Cause" or as a result of your death or "Permanent Disability"),
you will receive upon termination of your employment with the Company a
supplemental pension benefit equal to the difference between the benfit
calculated using your actual service and the benefit calculated assuming you had
an additional three (3) years of credited service. This supplemental pension
benefit will be calculated using the provisions of the qualified Pension Plan
and the non-qualified Supplemental Benefits Plan in effect at the time of the
termination of your employment. This benefit is a non-qualified, unfounded
deferred compensation arrangement. For purposes of this letter, the terms
"Cause" and "Permanent Disability" are defined in the Company's Key Executive
Severance Protection Plan.

This letter is not a contract or offer of a contract of employment and shall not
be deemed as such. Employment at Burlington is pursuant to the
Employment-At-Will Doctrine.

Steve, I am delighted that you will be joining the Company and look forward to
working with you.

Sincerely,

Bobby S. Shackouls
