         ARTICLE III. POWERS, DUTIES AND RIGHTS OF THE GUARANTEE TRUSTEE


                  Section 3.1. Powers and Duties of the Guarantee Trustee.

                  (a) This Guarantee Agreement shall be held by the Guarantee
Trustee for the benefit of the Holders, and the Guarantee Trustee shall not
transfer this Guarantee Agreement to any Person except a Holder exercising his
or her rights pursuant to Section 5.4(iv) or to a Successor Guarantee Trustee on
acceptance by such Successor Guarantee Trustee of its appointment to act as
Successor Guarantee Trustee. The right, title and interest of the Guarantee
Trustee shall automatically vest in any Successor Guarantee Trustee, upon
acceptance by such Successor Guarantee Trustee of its appointment hereunder, and
such vesting and cessation of title shall be effective whether or not
conveyancing documents have been executed and delivered pursuant to the
appointment of such Successor Guarantee Trustee.

                  (b) If an Event of Default has occurred and is continuing, the
Guarantee Trustee shall enforce this Guarantee Agreement for the benefit of the
Holders.

                  (c) The Guarantee Trustee, before the occurrence of any Event
of Default and after the curing or waiver of all Events of Default that may have
occurred, shall undertake to perform only such duties as are specifically set
forth in this Guarantee Agreement, and no implied covenants shall be read into
this Guarantee Agreement against the Guarantee Trustee. In case an Event of
Default has occurred (that has not been cured or waived pursuant to Section
2.6), the Guarantee Trustee shall exercise such of the rights and powers vested
in it by this Guarantee Agreement, and use the same degree of care and skill in
its exercise thereof, as a prudent person would exercise or use under the
circumstances in the conduct of his or her own affairs.

                  (d) No provision of this Guarantee Agreement shall be
construed to relieve the Guarantee Trustee from liability for its own negligent
action, its own negligent failure to act or its own willful misconduct, except
that:

                      (i) prior to the occurrence of any Event of Default and
         after the curing or waiving of all such Events of Default that may have
         occurred:

                               (A) the duties and obligations of the Guarantee
                  Trustee shall be determined solely by the express provisions
                  of this Guarantee Agreement, and the Guarantee Trustee shall
                  not be liable except for the performance of such duties and
                  obligations as are specifically set forth in this Guarantee
                  Agreement; and


   11
                                      -8-


                               (B) in the absence of bad faith on the part of
                  the Guarantee Trustee, the Guarantee Trustee may conclusively
                  rely, as to the truth of the statements and the correctness of
                  the opinions expressed therein, upon any certificates or
                  opinions furnished to the Guarantee Trustee and conforming to
                  the requirements of this Guarantee Agreement; but in the case
                  of any such certificates or opinions that by any provision
                  hereof or of the Trust Indenture Act are specifically required
                  to be furnished to the Guarantee Trustee, the Guarantee
                  Trustee shall be under a duty to examine the same to determine
                  whether or not they conform to the requirements of this
                  Guarantee Agreement;

                     (ii) the Guarantee Trustee shall not be liable for any
         error of judgment made in good faith by a Responsible Officer of the
         Guarantee Trustee, unless it shall be proved that the Guarantee Trustee
         was negligent in ascertaining the pertinent facts upon which such
         judgment was made;

                    (iii) the Guarantee Trustee shall not be liable with respect
         to any action taken or omitted to be taken by it in good faith in
         accordance with the direction of the Holders of not less than a
         Majority in liquidation preference of the Preferred Securities relating
         to the time, method and place of conducting any proceeding for any
         remedy available to the Guarantee Trustee, or exercising any trust or
         power conferred upon the Guarantee Trustee under this Guarantee
         Agreement; and

                     (iv) no provision of this Guarantee Agreement shall require
         the Guarantee Trustee to expend or risk its own funds or otherwise
         incur personal financial liability in the performance of any of its
         duties or in the exercise of any of its rights or powers, if the
         Guarantee Trustee shall have reasonable grounds for believing that the
         repayment of such funds or liability is not reasonably assured to it
         under the terms of this Guarantee Agreement or adequate indemnity
         against such risk or liability is not reasonably assured to it.

                  Section 3.2. Certain Rights of Guarantee Trustee.

                  (a)  Subject to the provisions of Section 3.1:

                      (i) The Guarantee Trustee may rely and shall be fully
         protected in acting or refraining from acting upon any resolution,
         certificate, statement, instrument, opinion, report, notice, request,
         direction, consent, order, bond, debenture, note, other evidence of
         indebtedness or other paper or document reasonably believed by it to be
         genuine and to have been signed, sent or presented by the proper party
         or parties.

                                      -9-


                     (ii) Any direction or act of the Guarantor contemplated by
         this Guarantee Agreement shall be sufficiently evidenced by an
         Officer's Certificate unless otherwise prescribed herein.

                    (iii) Whenever, in the administration of this Guarantee
         Agreement, the Guarantee Trustee shall deem it desirable that a matter
         be proved or established before taking, suffering or omitting to take
         any action hereunder, the Guarantee Trustee (unless other evidence is
         herein specifically prescribed) may, in the absence of bad faith on its
         part, request and rely upon an Officers' Certificate which, upon
         receipt of such request from the Guarantee Trustee, shall be promptly
         delivered by the Guarantor.

                     (iv) The Guarantee Trustee may consult with legal counsel,
         and the written advice or opinion of such legal counsel with respect to
         legal matters shall be full and complete authorization and protection
         in respect of any action taken, suffered or omitted to be taken by it
         hereunder in good faith and in accordance with such advice or opinion.
         Such legal counsel may be legal counsel to the Guarantor or any of its
         Affiliates and may be one of its employees. The Guarantee Trustee shall
         have the right at any time to seek instructions concerning the
         administration of this Guarantee Agreement from any court of competent
         jurisdiction.

                      (v) The Guarantee Trustee shall be under no obligation to
         exercise any of the rights or powers vested in it by this Guarantee
         Agreement at the request or direction of any Holder, unless such Holder
         shall have provided to the Guarantee Trustee such adequate security and
         indemnity as would satisfy a reasonable person in the position of the
         Guarantee Trustee, against the costs, expenses (including attorneys'
         fees and expenses) and liabilities that might be incurred by it in
         complying with such request or direction, including such reasonable
         advances as may be requested by the Guarantee Trustee; provided that,
         nothing contained in this Section 3.2(a)(v) shall be taken to relieve
         the Guarantee Trustee, upon the occurrence of an Event of Default, of
         its obligation to exercise the rights and powers vested in it by this
         Guarantee Agreement.

                     (vi) The Guarantee Trustee shall not be bound to make any
         investigation into the facts or matters stated in any resolution,
         certificate, statement, instrument, opinion, report, notice, request,
         direction, consent, order, bond, debenture, note, other evidence of
         indebtedness or other paper or document, but the Guarantee Trustee, in
         its discretion, may make such further inquiry or investigation into
         such facts or matters as it may see fit.

                    (vii) The Guarantee Trustee may execute any of the trusts or
         powers hereunder or perform any duties hereunder either directly or by
         or through its agents or attorneys, and the Guarantee Trustee shall not
         be responsible for any misconduct or


   13
                                      -10-


         negligence on the part of any such agent or attorney appointed with due
         care by it hereunder.

                   (viii) Any action taken by the Guarantee Trustee or its
         agents hereunder shall bind the holders, and the signature of the
         Guarantee Trustee or its agents alone shall be sufficient and effective
         to perform such action. No third party shall be required to inquire as
         to the authority of the Guarantee Trustee to so act or as to its
         compliance with any of the terms and provisions of this Guarantee
         Agreement, both of which shall be conclusively evidenced by the
         Guarantee's or its agent's taking such action.

                     (ix) Whenever in the administration of this Guarantee
         Agreement the Guarantee Trustee shall deem it desirable to receive
         instructions with respect to enforcing any remedy or right or taking
         any other action hereunder, the Guarantee Trustee (A) may request
         instructions from the Holders of a Majority in Liquidation Amount of
         the Securities, (B) may refrain from enforcing such remedy or right or
         taking such other action until such instructions are received, and (C)
         shall be protected in acting in accordance with such instructions.

                  (b) No provision of this Guarantee Agreement shall be deemed
to impose any duty or obligation on the Guarantee Trustee to perform any act or
acts or exercise any right, power, duty or obligation conferred or imposed on it
in any jurisdiction in which it shall be illegal, or in which the Guarantee
Trustee shall be unqualified or incompetent in accordance with applicable law,
to perform any such act or acts or to exercise any such right, power, duty or
obligation. No permissive power or authority available to the Guarantee Trustee
shall be construed to be a duty to act in accordance with such power and
authority.

                  Section 3.3. Indemnity.

                  The Guarantor agrees to indemnify the Guarantee Trustee for,
and to hold it harmless against, any loss, liability or expense incurred without
negligence or bad faith on the part of the Guarantee Trustee, arising out of or
in connection with the acceptance or administration of this Guarantee Agreement,
including the costs and expenses of defending itself against any claim or
liability in connection with the exercise or performance of any of its powers or
duties hereunder. The Guarantee Trustee will not claim or exact any lien or
charge on any Guarantee Payments as a result of any amount due to it under this
Guarantee Agreement. The provisions of this Section 3.3 shall survive the
termination of this Guarantee Agreement or the removal or resignation of the
Guarantee Trustee.

                          ARTICLE IV. GUARANTEE TRUSTEE


                  Section 4.1. Guarantee Trustee: Eligibility.

                  (a)  There shall at all times be a Guarantee Trustee which
shall:

                      (i)  not be an Affiliate of the Guarantor; and

                     (ii) be a Person that is eligible pursuant to the Trust
         Indenture Act to act as such and has a combined capital and surplus of
         at least $50,000,000, and shall be a corporation meeting the
         requirements of Section 310(c) of the Trust Indenture Act. If such
         corporation publishes reports of condition at least annually, pursuant
         to law or to the requirements of the supervising or examining
         authority, then, for the purposes of this Section and to the extent
         permitted by the Trust Indenture Act, the combined capital and surplus
         of such corporation shall be deemed to be its combined capital and
         surplus as set forth in its most recent report of condition so
         published.

                  (b) If at any time the Guarantee Trustee shall cease to be
eligible to so act under Section 4.1(a), the Guarantee Trustee shall immediately
resign in the manner and with the effect set out in Section 4.2(c).

                  (c) If the Guarantee Trustee has or shall acquire any
"conflicting interest" within the meaning of Section 310(b) of the Trust
Indenture Act, the Guarantee Trustee and Guarantor shall in all respects comply
with the provisions of Section 310(b) of the Trust Indenture Act.

                  Section 4.2. Appointment, Removal and Resignation of the
Guarantee Trustee.


                  (a)  Subject to Section 4.2(b), the Guarantee Trustee may be
appointed or removed without cause at any time by the Guarantor.

                  (b) The Guarantee Trustee shall not be removed until a
Successor Guarantee Trustee has been appointed and has accepted such appointment
by written instrument executed by such Successor Guarantee Trustee and delivered
to the Guarantor.

                  (c) The Guarantee Trustee appointed hereunder shall hold
office until a Successor Guarantee Trustee shall have been appointed or until
its removal or resignation. The Guarantee Trustee may resign from office
(without need for prior or subsequent accounting) by an instrument in writing
executed by the Guarantee Trustee and delivered to the Guarantor, which
resignation shall not take effect until a Successor Guarantee Trustee has been
appointed


   15
                                      -12-


and has accepted such appointment by instrument in writing executed by such
Successor Guarantee Trustee and delivered to the Guarantor and the resigning
Guarantee Trustee.

                  (d) If no Successor Guarantee Trustee shall have been
appointed and accepted appointment as provided in this Section 4.2 within 60
days after delivery to the Guarantor of an instrument of resignation, the
resigning Guarantee Trustee may petition, at the expense of the Guarantor, any
court of competent jurisdiction for appointment of a Successor Guarantee
Trustee. Such court may thereupon, after prescribing such notice, if any, as it
may deem proper, appoint a Successor Guarantee Trustee.


                              ARTICLE V. GUARANTEE


                  Section 5.1. Guarantee.

                  The Guarantor irrevocably and unconditionally agrees to pay in
full to the Holders the Guarantee Payments (without duplication of amounts
theretofore paid by or on behalf of the Issuer), as and when due, regardless of
any defense, right of set-off or counterclaim which the Issuer may have or
assert. The Guarantor's obligation to make a Guarantee Payment may be satisfied
by direct payment of the required amounts by the Guarantor to the Holders or by
causing the Issuer to pay such amounts to the Holders.

                  Section 5.2. Waiver of Notice and Demand.

                  The Guarantor hereby waives notice of acceptance of the
Guarantee Agreement and of any liability to which it applies or may apply,
presentment, demand for payment, any right to require a proceeding first against
the Guarantee Trustee, Issuer or any other Person before proceeding against the
Guarantor, protest, notice of nonpayment, notice of dishonor, notice of
redemption and all other notices and demands.

                  Section 5.3. Obligations Not Affected.

                  The obligations, covenants, agreements and duties of the
Guarantor under this Guarantee Agreement shall in no way be affected or impaired
by reason of the happening from time to time of any of the following:

                  (a) the release or waiver, by operation of law or otherwise,
         of the performance or observance by the Issuer of any express or
         implied agreement, covenant, term or condition relating to the
         Securities to be performed or observed by the Issuer;

                  (b) the extension of time for the payment by the Issuer of all
         or any portion of the Distributions (other than an extension of time
         for payment of Distributions that


   16
                                      -13-


         results from the extension of any interest payment period on the
         Debentures as so provided in the Indenture), Redemption Price,
         Liquidation Distribution or any other sums payable under the terms of
         the Securities or the extension of time for the performance of any
         other obligation under, arising out of, or in connection with, the
         Securities;

                  (c) any failure, omission, delay or lack of diligence on the
         part of the Holders to enforce, assert or exercise any right,
         privilege, power or remedy conferred on the Holders pursuant to the
         terms of the Securities, or any action on the part of the Issuer
         granting indulgence or extension of any kind;

                  (d) the voluntary or involuntary liquidation, dissolution,
         sale of any collateral, receivership, insolvency, bankruptcy,
         assignment for the benefit of creditors, reorganization, arrangement,
         composition or readjustment of debt of, or other similar proceedings
         affecting, the Issuer or any of the assets of the Issuer;

                  (e)  any invalidity of, or defect or deficiency in, the
         Securities;

                  (f)  the settlement or compromise of any obligation guaranteed
         hereby or hereby incurred; or

                  (g) any other circumstance whatsoever that might otherwise
         constitute a legal or equitable discharge or defense of a guarantor, it
         being the intent of this Section 5.3 that the obligations of the
         Guarantor hereunder shall be absolute and unconditional under any and
         all circumstances.

                  There shall be no obligation of the Holders to give notice to,
or obtain the consent of, the Guarantor with respect to the happening of any of
the foregoing.

                  Section 5.4. Rights of Holders.

                  The Guarantor expressly acknowledges that: (i) this Guarantee
Agreement will be deposited with the Guarantee Trustee to be held for the
benefit of the Holders; (ii) the Guarantee Trustee has the right to enforce this
Guarantee Agreement on behalf of the Holders; (iii) the Holders of a Majority in
liquidation preference of the Securities have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the
Guarantee Trustee in respect of this Guarantee Agreement or exercising any trust
or power conferred upon the Guarantee Trustee under this Guarantee Agreement;
and (iv) if the Guarantee Trustee fails to enforce this Guarantee Agreement
after a Holder has made a written request for the Guarantee Trustee to do so,
any Holder may, to the extent permitted by law, institute a legal proceeding
directly against the Guarantor to enforce its rights under this Guarantee
Agreement, without first instituting a legal proceeding against the Guarantee
Trustee, the Issuer or any other Person. Notwithstanding the foregoing, if the
Guarantor has failed to


   17
                                      -14-


make a Guarantee Payment, a Holder may directly institute a proceeding against
the Guarantor for enforcement of this Guarantee Agreement for such payment. The
Guarantor waives, any right or remedy to require that any action on this
Guarantee Agreement be brought first against the Issuer or any other Person or
entity before proceeding directly against the Guarantor.

                  Section 5.5. Guarantee of Payment.

                  This Guarantee Agreement creates a guarantee of payment and
not of collection. This Guarantee Agreement will not be discharged except by
payment of the Guarantee Payments in full (without duplication of amounts
theretofore paid by the Issuer) or upon distribution of Debentures to Holders as
provided in the Declaration of Trust.

                  Section 5.6. Subrogation.

                  The Guarantor shall be subrogated to all (if any) rights of
the Holders against the Issuer in respect of any amounts paid to the Holders by
the Guarantor under this Guarantee Agreement and shall have the right to waive
payment by the Issuer pursuant to Section 5.1; provided, however, that the
Guarantor shall not (except to the extent required by mandatory provisions of
law) be entitled to enforce or exercise any rights which it may acquire by way
of subrogation or any indemnity, reimbursement or other agreement, in all cases
as a result of payment under this Guarantee Agreement, if at the time of any
such payment, any amounts are due and unpaid under this Guarantee Agreement. If
any amount shall be paid to the Guarantor in violation of the preceding
sentence, the Guarantor agrees to hold such amount in trust for the Holders and
to pay over such amount to the Holders.

                  Section 5.7. Independent Obligations.

                  The Guarantor acknowledges that its obligations hereunder are
independent of the obligations of the Issuer with respect to the Securities and
that the Guarantor shall be liable as principal and as debtor hereunder to make
Guarantee Payments pursuant to the terms of this Guarantee Agreement
notwithstanding the occurrence of any event referred to in subsections (a)
through (g), inclusive, of Section 5.3 hereof.


                     ARTICLE VI. COVENANTS AND SUBORDINATION


                  Section 6.1. Subordination.

                  This Guarantee Agreement will constitute an unsecured
obligation of the Guarantor and will rank subordinate and junior in right of
payment to all Senior Indebtedness and Subordinated Indebtedness of the
Guarantor. If an Event of Default has occurred and is continuing under the
Declaration of Trust, the rights of the holders of the Common Securities to


   18
                                      -15-


receive Guarantee Payments hereunder shall be subordinated to the rights of the
holders of Preferred Securities to receive Guarantee Payments under this
Guarantee.

                  Section 6.2. Pari Passu Guarantees.

                  This Guarantee Agreement shall rank pari passu with any
similar Guarantee Agreements issued by the Guarantor on behalf of the holders of
Preferred Securities issued by Burlington Resources Capital I.


                            ARTICLE VII. TERMINATION


                  Section 7.1. Termination.

                  This Guarantee Agreement shall terminate and be of no further
force and effect upon (i) full payment of the Redemption Price of all
Securities, (ii) the distribution of Debentures to the Holders in exchange for
all of the Securities or (iii) full payment of the amounts payable in accordance
with the Declaration of Trust upon liquidation of the Issuer. Notwithstanding
the foregoing, this Guarantee Agreement will continue to be effective or will be
reinstated, as the case may be, if at any time any Holder must restore payment
of any sums paid with respect to Preferred Securities or this Guarantee
Agreement.


                           ARTICLE VIII. MISCELLANEOUS


                  Section 8.1. Successors and Assigns.

                  All guarantees and agreements contained in this Guarantee
Agreement shall bind the successors, assigns, receivers, trustees and
representatives of the Guarantor and shall inure to the benefit of the Holders
of the Securities then outstanding. Except in connection with a consolidation,
merger or sale involving the Guarantor that is permitted under Article 5 of the
Indenture and pursuant to which the assignee agrees in writing to perform the
Guarantor's obligations hereunder, the Guarantor shall not assign its
obligations hereunder.

                  Section 8.2. Amendments.

                  Except with respect to any changes which do not adversely
affect the rights of the Holders in any material respect (in which case no
consent of the Holders will be required), this Guarantee Agreement may only be
amended with the prior approval of the Holders of not less than a Majority in
liquidation preference of all the outstanding Preferred Securities. The


   19
                                      -16-


provisions of Article VI of the Declaration of Trust concerning meetings of the
Holders shall apply to the giving of such approval.

Holders and is not separately transferable from the Preferred Securities.

                  Section 8.5. Interpretation.

                  In this Guarantee Agreement, unless the context otherwise
requires:

                  (a) capitalized terms used in this Guarantee Agreement but not
         defined in the preamble hereto have the respective meanings assigned to
