                              OFFICERS' CERTIFICATE

     Each of the undersigned officers of Burlington Resources Finance Company,

Scotia, Canada (the "Company"), in accordance with Sections 1.03 and 3.01 of the
Indenture, dated as of February 12, 2001 between the Company and Citibank, N.A.,
as Trustee (the "Indenture"), does hereby certify as follows (capitalized terms
used but not otherwise defined herein shall have the meanings assigned to such
terms in the Indenture):

     1. We have read the provisions of the Indenture pursuant to which the form
and terms of the Securities (as defined below) have been established and the
definitions contained in the Indenture relating thereto. We have also reviewed
such other corporate documents and records, and made such examination or
investigation, as each of us considers is necessary to enable us to express an
informed opinion as to whether the covenants and conditions precedent to the
establishment of the form and terms of the Securities and the authentication and
delivery of the Securities by the Trustee have been or will be complied with,
and in our opinion, all such covenants and conditions precedent have been
complied with.

     2. The Company has registered under the Securities Act of 1933, as amended,
and established one series of Securities under the Indenture, titled 5.60%
Exchange Notes due December 1, 2006 (the "2006 Notes"), one series of Securities
under the Indenture, titled 6.50% Exchange Notes due December 1, 2011 (the "2011
Notes"), and one series of Securities under the Indenture, titled 7.40% Exchange
Notes due December 1, 2031 (the "2031 Notes" and, collectively with the 2006
Notes and the 2011 Notes, the "Securities"), which are represented by one or
more certificates (each a "Global Certificate") registered in the name of The
Depository Trust Company or its nominee ("DTC"), as depository for the
Securities.

     3. On the date hereof, $ aggregate principal amount of the 2006 Notes, $
aggregate principal amount of the 2011 Notes and $ aggregate principal amount of
the 2031 Notes will be issued. The Company shall be entitled to issue additional
Securities (of each or all series) which have identical terms as any of the
Securities issued on the date hereof, other than with respect to the date of
issuance, to issue price and to the special mandatory redemption. Each of the
series of Securities issued on the date hereof and any additional Securities of
a particular series issued in the future shall be treated as a single class for
all purposes of the Indenture. The Securities are not limited in aggregate
principal amount.

     4. The principal amount of the 2006 Notes is payable on December 1, 2006,
the principal amount of the 2011 Notes is payable on December 1, 2011 and the
principal amount of the 2031 Notes is payable on December 1, 2031.

     5. The 2006 Notes shall bear interest at the rate of 5.60% per annum,
beginning on November 16, 2001 or, if interest has been paid on the outstanding
notes, from the most recent date to which interest has been paid, the 2011 Notes
shall bear interest at the rate of 6.50% per annum, beginning on November 16,
2001 or, if interest has been paid on the outstanding notes, from the most
recent date to which interest has been paid, and the 2031 Notes shall bear
interest at the rate of 7.40% per annum, beginning on November 16, 2001 or, if
interest has been paid on the outstanding notes, from the most recent date to
which interest has been paid. Interest on the Securities will be computed on the
basis of a 360-day year comprised of twelve 30-day months. Interest shall be
payable semiannually on June 1 and December 1 in each year (each, an "Interest
Payment Date"), commencing on the first Interest Pay-


<PAGE>
                                      -2-


ment Date after the issue date of the Securities or, if interest has not been
paid on the outstanding notes, on June 1, 2002, until payment of the principal
sum has been made or duly provided for. The interest so payable, and punctually
paid or duly provided for, on any Interest Payment Date or within 5 days
thereafter will be paid to the person in whose name the Securities are
registered at the close of business on May 15 or November 15, as the case may
be, next preceding such Interest Payment Date.

     6. The principal of and the interest on the Securities shall be payable at
the Company's office or agency maintained for such purpose in the Borough of

Street, New York, NY 10005, in immediately available (same day) funds to the
registered holders of the Securities, which initially shall be DTC or its
nominee; provided however, that at the option of the Company payment of interest
may be made by check mailed to the address of the person entitled thereto as
such address appears in the Securities Register.

     7. The Securities shall be subject to a Special Mandatory Redemption as
more fully described in Exhibit A hereto. A failure by the Company to make a
Special Mandatory Redemption when required to do so shall constitute an Event of
Default under the Indenture. Since the Company complied with its obligation
under the Special Mandatory Redemption, this provision no longer has any effect
and the Company will not be required to redeem the Securities pursuant to this
provision.

     8. Each series of the Securities may be redeemed at the option of the
Company, in whole or in part, upon not less than 30 nor more than 60 days'
notice to registered holders thereof. The Securities may be redeemed at a
redemption price applicable to each series of Securities equal to the greater of
(a) 100% of the principal amount of such series plus accrued interest to the
redemption date or (b) the sum of the present values of the remaining scheduled
payments of principal and interest (exclusive of interest accrued to the date of
redemption) discounted to the redemption date on a semiannual basis (assuming a
360-day year consisting of twelve 30-day months) at the Treasury Rate (as
defined in Exhibit A hereto) plus 25 basis points, plus accrued and unpaid
interest on the principal amount of such series being redeemed to the redemption
date.

     9. The Securities are not entitled to the benefit of any sinking fund.

     10. The Securities are subject to defeasance in accordance with Article
Four of the Indenture.

     11. The form of the Global Securities shall be substantially as attached
hereto as Exhibit A.

     12. Citibank, N.A. is hereby designated and appointed as Paying Agent and
Securities Registrar with respect to the Securities.

of Governors of the Federal Reserve System and which establishes yields on
actively traded United States Treasury securities adjusted to constant maturity
under the caption "Treasury Constant Maturities," for the maturity corresponding

straight line basis, rounding to the nearest month) or (ii) if such release (or
any successor release) is not published during the week preceding the
calculation date or does not contain such yields, the rate per annum equal to
the semiannual equivalent yield to maturity of the Comparable Treasury Issue,

comparable maturity to the remaining term of the Securities.

     "Comparable Treasury Price" means, with respect to any redemption date, (A)

amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities under the Indenture at
any time by the Company and the Trustee with the consent of the Holders of a
majority in aggregate principal amount of the Securities affected thereby,
voting as a single class (which may include the Securities), at the time
outstanding. The Indenture also contains provisions permitting the Company and
the Trustee to amend certain provisions of the Indenture without the consent of
the Holders of the Securities.

governmental charges shall be paid by the Company).

"Indenture"), between the Company and Citibank N.A., as Trustee (the "Trustee,"
which term includes any successor trustee under the Indenture). The Securities
shall be fully and unconditionally guaranteed by Burlington Resources Inc., a
Delaware corporation (the "Guarantor"), pursuant to a Guarantee Agreement dated
as of February 12, 2001 by the Guarantor in favor of the holders of Securities.
The terms of this Security include those stated in the Indenture and in the
Officers' Certificate issued thereunder and those made part of the Indenture by
reference to the Trust Indenture Act of 1939, as in effect on the date of the
Indenture. Reference is hereby made to the Indenture and the applicable
officers' certificate issued thereunder for a statement of the respective
rights, limitation of rights, duties and immunities thereunder of the Company,
the Trustee and the Holders and of the terms upon which the Securities are, and
are to be, authenticated and delivered.

     The Securities are a series of Securities issued or to be issued by the
Company under the Indenture, and this Series is unlimited in aggregate principal
amount. As of the Original Issue Date, $ principal amount of Notes of this
Series will be issued. The Indenture provides that the Securities of the Company
referred to therein ("Securities"), may be issued in one or more Series, which
different Series may be issued in such aggregate principal amounts and on such

provisions for determining such interest rate or rates and adjustments thereto,
maturity, redemption (optional and mandatory), covenants and Events of Default)
as may be provided in the officers' certificates or supplemental indentures
relating to the several Series.

     The notes which were exchanged for the Securities contained a special
mandatory redemption provision which no longer has any effect and the Company
will not be required to redeem the Securities pursuant to such provision.

     The Securities are subject to redemption upon not less than 30 nor more
than 60 days notice by mail, in whole or in part, at the option of the Company
at any time at a redemption price equal to the greater of (i) 100% of the
principal amount of such Securities plus accrued and unpaid interest to the
redemption date or (ii) the sum of the present values of the remaining scheduled
payments of principal and interest thereon (exclusive of interest accrued to the
date of redemption) discounted to the redemption date on a semiannual basis
(assuming a 360-day year consisting of twelve 30-day months) at the Treasury
Rate plus 25 basis points plus accrued and unpaid interest thereon to the
redemption date.

of Governors of the Federal Reserve System and which establishes yields on
actively traded United States Treasury securities adjusted to constant maturity
under the caption "Treasury Constant Maturities," for the maturity corresponding
to the Comparable Treasury Issue (if no maturity is within three months before
or after the Remaining Life, yields for the two published maturities most
closely corresponding to the Comparable Treasury Issue shall be determined and
the Treasury Rate shall be interpolated or extrapolated from such yields on a
straight line basis, rounding to the nearest month) or (ii) if such release (or
any successor release) is not published during the week preceding the
calculation date or does not contain such yields, the rate per annum equal to
the semiannual equivalent yield to maturity of the Comparable Treasury Issue,
calculated using a price for the Comparable Treasury Issue (expressed as a
percentage of its principal amount) equal to the Comparable Treasury Price for
such redemption date. The Treasury Rate shall be calculated on the third
Business Day preceding the redemption date.

comparable maturity to the remaining term of the Securities.

     "Comparable Treasury Price" means, with respect to any redemption date, (A)
the average of four Reference Treasury Dealer Quotations for such redemption

such Reference Treasury Dealer Quotations, the average of all such Quotations.

     "Independent Investment Banker" means Merrill Lynch, Pierce, Fenner & Smith

Treasury Issue, an independent investment banking institution of national

& Smith Incorporated and Morgan Stanley & Co. Incorporated and two other primary
U.S. Government securities dealers in New York City (each, a "Primary Treasury
Dealer") and their respective successors, provided, however, that if any of the
foregoing shall cease to be a

                                      -3-


Primary Treasury Dealer, the Company will substitute therefor another Primary
Treasury Dealer and (ii) any other Primary Treasury Dealer selected by the
Company.

Reference Treasury Dealer at 5:00 p.m. on the third Business Day preceding such
redemption date.

the Securities may be declared due and payable in the manner and with the effect
provided in the Indenture. The Indenture provides that the Trustee or Holders of

certain conditions such declarations may be annulled and past defaults may be
waived.

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities under the Indenture at
any time by the Company and the Trustee with the consent of the Holders of a
majority in aggregate principal amount of the Securities affected thereby,
voting as a single class (which may include the Securities), at the time
outstanding. The Indenture also contains provisions permitting the Company and
the Trustee to amend certain provisions of the Indenture without the consent of
the Holders of the Securities.

     No reference herein to the Indenture or the Officers' Certificate and no
provision of this Note or of the Indenture or the Officers' Certificate shall
alter or impair the obligation of the Company, which is absolute and

of this Security, the Securities are ex-

exchange, but the Company may require payment of a sum sufficient to cover any

exchanges pursuant to the Indenture in which case such transfer taxes or similar
governmental charges shall be paid by the Company).

Company, the Trustee and any agent of the Company or the Trustee may treat the
person in whose name this Note is registered as the owner hereof for all
purposes, whether or not this Security be overdue, and neither the Company, the

     This Security is one of a duly authorized issue of Securities of the

or to be issued pursuant to an Indenture, dated as of February 12, 2001 (the
"Indenture"), between the Company and Citibank N.A., as Trustee (the "Trustee,"
which term includes any successor trustee under the Indenture). The Securities
shall be fully and unconditionally guaranteed by Burlington Resources Inc., a
Delaware corporation (the "Guarantor"), pursuant to a Guarantee Agreement dated
as of February 12, 2001 by the Guarantor in favor of the holders of Securities.
The terms of this Security include those stated in the Indenture and in the
Officers' Certificate issued thereunder and those made part of the Indenture by
reference to the Trust Indenture Act of 1939, as in effect on the date of the
Indenture. Reference is hereby made to the Indenture and the applicable
officers' certificate issued thereunder for a statement of the respective
rights, limitation of rights, duties and immunities thereunder of the Company,
the Trustee and the Holders and of the terms upon which the Securities are, and
are to be, authenticated and delivered.

     The Securities are a series of Securities issued or to be issued by the
Company under the Indenture, and this Series is unlimited in aggregate principal
amount. As of the Original Issue Date, $ principal amount of Notes of this
Series will be issued. The Indenture provides that the Securities of the Company
referred to therein ("Securities"), may be issued in one or more Series, which
different Series may be issued in such aggregate principal amounts and on such
terms (including, but not limited to, terms relating to interest rate or rates,
provisions for determining such interest rate or rates and adjustments thereto,
maturity, redemption (optional and mandatory), covenants and Events of Default)
as may be provided in the officers' certificates or supplemental indentures
relating to the several Series.

     The notes which were exchanged for the Securities contained a special
mandatory redemption provision which no longer has any effect and the Company
will not be required to redeem the Securities pursuant to such provision.

     The Securities are subject to redemption upon not less than 30 nor more
than 60 days notice by mail, in whole or in part, at the option of the Company
at any time at a redemption price equal to the greater of (i) 100% of the
principal amount of such Securities plus accrued and unpaid interest to the
redemption date or (ii) the sum of the present values of the remaining scheduled
payments of principal and interest thereon (exclusive of interest accrued to the
date of redemption) discounted to the redemption date on a semiannual basis
(assuming a 360-day year consisting of twelve 30-day months) at the Treasury
Rate plus 25 basis points plus accrued and unpaid interest thereon to the
redemption date.

of Governors of the Federal Reserve System and which establishes yields on
actively traded United States Treasury securities adjusted to constant maturity
under the caption "Treasury Constant Maturities," for the maturity corresponding
to the Comparable Treasury Issue (if no maturity is within three months before
or after the Remaining Life, yields for the two published maturities most
closely corresponding to the Comparable Treasury Issue shall be determined and
the Treasury Rate shall be interpolated or extrapolated from such yields on a
straight line basis, rounding to the nearest month) or (ii) if such release (or
any successor release) is not published during the week preceding the
calculation date or does not contain such yields, the rate per annum equal to
the semiannual equivalent yield to maturity of the Comparable Treasury Issue,

Business Day preceding the redemption date.

comparable maturity to the remaining term of the Securities.

     "Comparable Treasury Price" means, with respect to any redemption date, (A)

foregoing shall cease to be a

redemption date.

waived.

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities under the Indenture at
any time by the Company and the Trustee with the consent of the Holders of a
majority in aggregate principal amount of the Securities affected thereby,
voting as a single class (which may include the Securities), at the time
outstanding. The Indenture also contains provisions permitting the Company and
the Trustee to amend certain provisions of the Indenture without the consent of
the Holders of the Securities.

     No reference herein to the Indenture or the Officers' Certificate and no
provision of this Note or of the Indenture or the Officers' Certificate shall
alter or impair the obligation of the Company, which is absolute and

governmental charges shall be paid by the Company).
