                               ITEMS ONE AND TWO
 
BUSINESS AND PROPERTIES
 
     Burlington Resources Inc. ("BR") is a holding company engaged, through its
principal subsidiaries, Burlington Resources Oil & Gas Company and The Louisiana
Land and Exploration Company ("LL&E"), acquired October 22, 1997, and their
affiliated companies (collectively the "Company"), in the exploration,
development, production and marketing of oil and gas.
 
     For additional information concerning Items One and Two, see pages 6
through 19 of the BR 1998 Annual Report, which information is incorporated
herein by reference.
 
OTHER MATTERS
 
     Competition.  The Company actively competes for reserve acquisitions,
exploration leases and sales of oil and gas, frequently against companies with
substantially larger financial and other resources. In its marketing activities,
the Company competes with numerous companies for the sale of oil, gas and
natural gas liquids ("NGLs"). Competitive factors in the Company's business
include price, contract terms, quality of service, pipeline access,
transportation discounts and distribution efficiencies.
 
     Regulation of Oil and Gas Production, Sales and Transportation.  The oil
and gas industry is subject to regulation by numerous national, state and local
governmental agencies and departments in the countries in which the Company
operates, compliance with which is often difficult and costly and some of which
carry substantial noncompliance penalties and risks. Statutes, rules,
regulations or guidelines require drilling permits, drilling bonds and operating
reports. Most jurisdictions in which the Company operates also have statutes,
rules, regulations or guidelines governing conservation matters, including the
unitization or pooling of oil and gas properties and the establishment of
maximum rates of production from oil and gas wells. Many jurisdictions also
limit production to the market demand for oil and gas. Such statutes, rules,
regulations or guidelines may limit the rate at which oil and gas could
otherwise be produced from the Company's properties. All of the Company's sales
of its domestic gas are deregulated.
 
     The Company operates various gathering systems. The United States
Department of Transportation and certain state agencies regulate, under various
statutes, rules or regulations, the safety and operating aspects of the
transportation and storage activities of these facilities by prescribing
standards.
 
     The Federal Energy Regulatory Commission ("FERC") has implemented policies,
subject to court review, allowing interstate pipeline companies to negotiate
their rates with individual shippers. The FERC is also considering allowing the
interstate pipeline companies to negotiate tariffed terms and conditions of
service. The Company will monitor the effects of these programs on its marketing
efforts but does not expect that these actions will have a material adverse
effect on the consolidated financial position or results of operations of the
Company.
 
     Environmental Regulation.  Various federal, state and local laws and
regulations relating to the protection of the environment, including the
discharge of materials into the environment, may affect the Company's domestic
operations and costs as a result of their effect on oil and gas exploration,
development and production operations. In addition, certain of the Company's
international operations are subject to environmental regulations administered
by foreign governments, including political subdivisions thereof, or by
international organizations.
 
     Offshore oil and gas operations in the United States ("U.S.") are subject
to regulations of the U.S. Department of the Interior which currently imposes
absolute liability upon the lessee under a federal lease for the cost of
pollution cleanup resulting from the lessee's operations and could subject the
lessee to possible liability for pollution damages. In the event of a serious
incident of pollution, the U.S.
 
                                        1
<PAGE>   4
 
Department of the Interior may require a lessee under a federal lease to suspend
or cease operations in the affected area.
 
     The Company believes it is in substantial compliance with applicable
environmental laws and regulations. The Company does not anticipate that it will
be required under current environmental laws and regulations to expend amounts
that will have a material adverse effect on the consolidated financial position
or results of operations of the Company.
 
     Filings of Reserve Estimates With Other Agencies.  During 1998, the Company
filed estimates of oil and gas reserves for the year 1997 with the Department of
Energy. These estimates were not materially different from the reserve data
presented. For information concerning proved oil and gas reserves, see page 48
of the BR 1998 Annual Report, which information is incorporated herein by
reference.
 
EMPLOYEES
 
     The Company had 1,678 and 1,819 employees at December 31, 1998 and 1997,
respectively. Currently, the Company has no union employees.
 
                                   ITEM THREE
 
LEGAL PROCEEDINGS
 
     The Company is involved in several proceedings challenging payment of
royalties for its crude oil and natural gas production.
 
     On November 20, 1997, the Company and numerous other defendants entered
into a settlement agreement in a lawsuit styled as The McMahon Foundation, et
al. v. Amerada Hess Corporation, et al. This lawsuit is a proposed class action
consisting of both working interest owners and royalty owners against numerous
defendants, all of which are oil companies and/or purchasers of oil from oil
companies, including Burlington Resources Oil & Gas Company, formerly known as
Meridian Oil Inc. ("BROG") and LL&E. The plaintiffs allege that the defendants
conspired to fix, depress, stabilize and maintain at artificially low levels the
prices paid for oil by, among other things, setting their posted prices at
arbitrary levels below competitive market prices. Cases involving similar
allegations have been filed in federal courts in other states. On January 14,
1998, the United States Judicial Panel on Multidistrict Litigation issued an
order consolidating these cases and transferring the McMahon case to the United
States District Court for the Southern District of Texas in Corpus Christi. The
Company and other defendants have entered into a Settlement Agreement which
received preliminary approval by the Court on October 28, 1998. The Court has
set a hearing to finally determine the fairness, accuracy and reasonableness of
the Settlement Agreement beginning in April 1999.
 
     The Company is also involved in several governmental proceedings relating
to the payment of royalties. Various administrative proceedings are pending
before the Minerals Management Service ("MMS") of the United States Department
of the Interior with respect to the proper valuation of oil and gas produced on
federal and Indian lands for purposes of paying royalties on production sold by
BROG to its affiliate, Burlington Resources Trading Inc. ("BRTI"), or gathered
by its affiliate, Burlington Resources Gathering Inc. In general, these
proceedings stem from regular MMS audits of the Company's royalty payments over
various periods of time and involve the interpretation of the relevant federal
regulations. Most of these administrative proceedings currently have been
suspended pending negotiations between the Company and the MMS to resolve their
disputes regarding the appropriate valuation methodology or pending resolution
of the federal False Claims Act litigation as hereinafter described.
 
     In late February 1998, the Company and numerous other oil and gas companies
received a complaint filed in the United States District Court for the Eastern
District of Texas in Lufkin in a lawsuit styled as United States of America ex
rel J. Benjamin Johnson, Jr., et al. v. Shell Oil Company, et
 
                                        2
<PAGE>   5
 
al. alleging violations of the civil False Claims Act. The United States has
intervened in this lawsuit as to some of the defendants, including the Company,
and has filed a separate complaint. This suit alleges that the Company underpaid
royalties for crude oil produced on federal and Indian lands through the use of
below-market posted prices in the sale of oil from BROG to BRTI. The suit
alleges that royalties paid by BROG based on these posted prices were lower than
the royalties allegedly required to be paid under federal regulations, and that
the forms filed by BROG with the MMS reporting the royalties paid were false,
thereby violating the civil False Claims Act. The Company and others have also
received document subpoenas and other inquiries from the Department of Justice
relating to the payment of royalties to the federal government for natural gas
production. These requests and inquiries have been made in the context of one or
more other False Claims Act cases brought by individuals which remain under seal
and are now being investigated by the Civil Division of the Department of
Justice. The Company has responded and continues to respond to these requests
and inquiries, but the Company does not know what action, if any, the Department
of Justice will take with regard to these other cases. If the government chooses
not to intervene and pursue these cases, the individuals who initially brought
these cases are free to pursue them in return for a share, if any, of any final
settlement or judgment. In addition, the Company has been advised that it is a
target of a criminal investigation by the United States Attorney for the
District of Wyoming into the alleged underpayment of oil and gas royalties. The
Company has responded to numerous grand jury document subpoenas in connection
with an investigation and is otherwise cooperating with the investigation.
Management cannot predict when the investigation will be completed or its
ultimate outcome.
 
     Based on the Company's present understanding of the various governmental
proceedings relating to royalty payments, descibed in the preceding two
paragraphs, the Company believes that it has substantial defenses to these
claims and intends to vigorously assert such defenses. However, in the event
that the Company is found to have violated the civil False Claims Act or is
indicted or convicted on criminal charges, the Company could be subjected to a
variety of sanctions, including treble damages, substantial monetary fines,
civil and/or criminal penalties and a temporary suspension from entering into
future federal mineral leases and other federal contracts for a defined period
of time. While the ultimate outcome and impact on the Company cannot be
predicted with certainty, management believes that the resolution of these
proceedings will have a material adverse effect on the consolidated financial
position of the Company, although results of operations and cash flows could be
significantly impacted in the reporting periods in which such matters are
resolved.
 
     In addition to the foregoing, the Company and its subsidiaries are named
defendants in numerous other lawsuits and named parties in numerous governmental
and other proceedings arising in the ordinary course of business. While the
outcome of these other lawsuits and proceedings cannot be predicted with
certainty, management believes these matters, other than the above-described
proceedings, will not have a material adverse effect on the consolidated
financial position, results of operations or cash flows of the Company.

FORWARD-LOOKING STATEMENTS
 
     The Company, in discussions of its future plans, objectives and expected
performance in periodic reports filed by the Company with the Securities and
Exchange Commission (or documents incorporated by reference therein) and in
written and oral presentations made by the Company, may include projections or
other forward-looking statements within the meaning of Section 27A of the
Securities Act of 1933 or Section 21E of the Securities Exchange Act of 1934, as
amended. Such projections and forward-looking statements are based on
assumptions which the Company believes are reasonable, but are by their nature
inherently uncertain. In all cases, there can be no assurance that such
assumptions will prove correct or that projected events will occur, and actual
results could differ materially from those projected. Some of the important
factors that could cause actual results to differ from any such projections or
other forward-looking statements follow.
 
     Commodity Pricing and Demand. Substantially all of the Company's crude oil
and natural gas production is sold on the spot market or under short-term
contracts at market sensitive prices. Spot market prices for domestic crude oil
and natural gas are subject to volatile trading patterns in the commodity
futures markets, including among others, the New York Mercantile Exchange
("NYMEX"), because of seasonal weather patterns, national supply and demand
factors and general economic conditions. Crude oil prices are also affected by
quality differentials, by worldwide political developments and by actions of the
Organization of Petroleum Exporting Countries. Although the futures markets
provide some indication of crude oil and natural gas prices for the subsequent
12 to 18 months, prices in the futures markets are subject to substantial
changes in relatively short periods of time.
 
                                        4
<PAGE>   7
 
     There is also a difference between the NYMEX futures contract price for a
particular month and the actual cash price received for that month in a U.S.
producing basin or at a U.S. market hub, which is referred to as the "basis
differential." Basis differentials, like the underlying commodity prices, can be
volatile because of regional supply and demand factors, including seasonal
factors and the availability and price of transportation to consuming areas.
 
     In the ordinary course and conduct of its business, the Company utilizes
futures contracts traded on the NYMEX and the Kansas City Board of Trade, and
over-the-counter price and basis swaps and options with major crude oil and
natural gas merchants and financial institutions to hedge its price risk
exposure related to the Company's U.S. production. The gains and losses realized
as a result of these derivatives transactions are substantially offset in the
cash market when the hedged commodity is delivered. In order to accommodate the
needs of its customers, the Company also uses price swaps to convert gas sold
under fixed price contracts to market prices.
 
     The Company uses a sensitivity analysis technique to evaluate the
hypothetical effect that changes in the market value of crude oil and natural
gas may have on the fair value of the Company's derivative instruments. At
December 31, 1998, the potential decrease in fair value of commodity derivative
instruments assuming a 10 percent adverse movement in the underlying commodities
would result in an 89% decrease in the net deferred amount.
 
     For purposes of calculating the hypothetical change in fair value, the
relevant variables are the type of commodity (crude oil or natural gas), the
commodity futures prices, the volatility of commodity prices and the basis and
quality differentials. The hypothetical change in fair value is calculated by
multiplying the difference between the hypothetical price (adjusted for any
basis or quality differentials) and the contractual price by the contractual
volumes.
 
     Changes in crude oil and natural gas prices (including basis differentials)
from those assumed in preparing projections and forward-looking statements could
cause the Company's actual financial results to differ materially from projected
financial results and can also impact the Company's determination of proved
reserves and the standardized measure of discounted future net cash flows
relative to crude oil and natural gas reserves. In addition, periods of sharply
lower commodity prices could affect the Company's production levels and/or cause
it to curtail capital spending projects and delay or defer exploration,
exploitation or development projects.
 
     Projections relating to the price received by the Company for natural gas
also rely on assumptions regarding the availability and pricing of
transportation to the Company's key markets. In particular, the Company has
contractual arrangements for the transportation of natural gas from the San Juan
Basin eastward to Eastern and Midwestern markets or to market hubs in Texas,
Oklahoma and Louisiana. The natural gas price received by the Company could be
adversely affected by any constraints in pipeline capacity to serve these
markets.
 
     Exploration and Production Risks. The Company's business is subject to all
of the risks and uncertainties normally associated with the exploration for and
development and production of crude oil and natural gas.
 
     Reserves which require the use of improved recovery techniques for
production are included in proved reserves if supported by a successful pilot
project or the operation of an installed program. The process of estimating
quantities of proved reserves is inherently uncertain and involves subjective
engineering and economic determinations. In this regard, changes in the economic
conditions (including commodity prices) or operating conditions (including,
without limitation, exploration, development and production costs and expenses
and drilling results from exploration and development activity) could cause the
Company's estimated proved reserves or production to differ from those included
in any such forward-looking statements or projections.
 
                                        5
<PAGE>   8
 
     Projecting future crude oil and natural gas production is imprecise.
Producing oil and gas reservoirs eventually have declining production rates.
Projections of production rates rely on certain assumptions regarding historical
production patterns in the area or formation tests for a particular producing
horizon. Actual production rates could differ materially from such projections.
Production rates depend on a number of additional factors, including commodity
prices, market demand and the political, economic and regulatory climate.
 
     Another major factor affecting the Company's production is its ability to
replace depleting reservoirs with new reserves through acquisition, exploration
or development programs. Exploration success is extremely difficult to predict
with certainty, particularly over the short term where the timing and extent of
successful results vary widely. Over the long term, the ability to replace
reserves depends not only on the Company's ability to locate crude oil and
natural gas reserves, but on the cost of finding and developing such reserves.
Moreover, development of any particular exploration or development project may
not be justified because of the commodity price environment at the time or
because of the Company's finding and development costs for such project. No
assurances can be given as to the level or timing of success that the Company
will be able to achieve in acquiring or finding and developing additional
reserves.
 
     Projections relating to the Company's production and financial results rely
on certain assumptions about the Company's continued success in its acquisition
and asset rationalization programs and in its cost management efforts.
 
     The Company's drilling operations are subject to various hazards common to
the oil and gas industry, including explosions, fires, and blowouts, which could
result in damage to or destruction of oil and gas wells or formations,
production facilities and other property and injury to people. They are also
subject to the additional hazards of marine operations, such as capsizing,
collision and damage or loss from severe weather conditions.
 
     Development Risk. A significant portion of the Company's development plans
involve large projects in the Gulf of Mexico and other areas. A variety of
factors affect the timing and outcome of such projects including, without
limitation, approval by the other parties owning working interests in the
project, receipt of necessary permits and approvals by applicable governmental
agencies, the availability of the necessary drilling equipment, delivery
schedules for critical equipment and arrangements for the gathering and
transportation of the produced hydrocarbons.
 
     Foreign Operations Risk. The Company's operations outside of the U.S. are
subject to risks inherent in foreign operations, including, without limitation,
the loss of revenue, property and equipment from hazards such as expropriation,
nationalization, war, insurrection and other political risks, increases in taxes
and governmental royalties, renegotiation of contracts with governmental
entities, changes in laws and policies governing operations of foreign-based
companies, currency restrictions and exchange rate fluctuations and other
uncertainties arising out of foreign government sovereignty over the Company's
international operations. Laws and policies of the U.S. affecting foreign trade
and taxation may also adversely affect the Company's international operations.
 
     The Company's ability to market oil and natural gas discovered or produced
in its foreign operations, and the price the Company could obtain for such
production, depends on many factors beyond the Company's control, including
ready markets for oil and natural gas, the proximity and capacity of pipelines
and other transportation facilities, fluctuating demand for oil and natural gas,
the availability and cost of competing fuels, and the effects of foreign
governmental regulation of oil and gas production and sales. Pipeline and
processing facilities do not exist in certain areas of exploration and,
therefore, any actual sales of the Company's production could be delayed for
extended periods of time until such facilities are constructed.
 
     Competition. The Company actively competes for property acquisitions,
exploration leases and sales of crude oil and natural gas, frequently against
companies with substantially larger financial and other resources. In its
marketing activities, the Company competes with numerous companies for gas
 
                                        6
<PAGE>   9
 
purchasing and processing contracts and for natural gas and NGLs at several
steps in the distribution chain. Competitive factors in the Company's business
include price, contract terms, quality of service, pipeline access,
transportation discounts and distribution efficiencies.
 
     Political and Regulatory Risk. The Company's operations are affected by
national, state and local laws and regulations such as restrictions on
production, changes in taxes, royalties and other amounts payable to governments
or governmental agencies, price or gathering rate controls and environmental
protection regulations. Changes in such laws and regulations, or interpretations
thereof, could have a significant effect on the Company's operations or
financial results.
 
     Potential Environmental Liabilities. The Company's operations are subject
to various national, state and local laws and regulations covering the discharge
of material into, and protection of, the environment. Such regulations affect
the costs of planning, designing, operating and abandoning facilities. The
Company expends considerable resources, both financial and managerial, to comply
with environmental regulations and permitting requirements. Although the Company
believes that its operations and facilities are in general compliance with
applicable environmental laws and regulations, risks of substantial costs and
liabilities are inherent in crude oil and natural gas operations. Moreover, it
is possible that other developments, such as increasingly strict environmental
laws, regulations and enforcement, and claims for damage to property or persons
resulting from the Company's current or discontinued operations, could result in
substantial costs and liabilities in the future.

      fees) paid by such Interested Stockholder in acquiring the largest number
      of shares of such class of stock previously acquired in any one
      transaction or series of related transactions, whether before or after the
      Interested Stockholder became an Interested Stockholder and (ii) the
      Interested Stockholder shall not have received the benefit, directly or

Disinterested Directors to all stockholders of this corporation whether or not
such statement is required under the 1934 Act. The statement shall contain any
recommendations as to the advisability of the Business Combination which the
Disinterested Directors, or any of them, may choose to state and, if deemed
advisable by the Disinterested Directors, an opinion of an investment banking
firm as to the fairness of the terms of such Business Combination. Such firm
shall be selected by the Disinterested Directors and be paid a fee for its
services by this corporation as approved by the Disinterested Directors.

      15.4 Amendment

    No amendment to this Certificate of Incorporation shall amend, alter, change
or repeal any of the provisions of Article 14 or of this Article 15 unless such
amendment shall receive the affirmative vote of not less than fifty-one percent

                                OTHER AMENDMENTS

                  Section 1. Designation and Amount. There shall be a series of
Preferred Stock, par value $.01 per share, of the Company which shall be
designated as "Series A Junior Participating Preferred Stock," par value $.01
per share, and the number of shares constituting such series shall be 3,250,000.
Such number of shares may be increased or decreased by resolution of the Board
of Directors; provided, that no decrease shall reduce the number of shares of
Series A Junior Participating Preferred Stock to a number less than that of the
shares then outstanding plus the number of shares issuable upon exercise of
outstanding rights, options or warrants or upon conversion of outstanding
securities issued by the Company.

               Section 2.  Dividends and Distributions.

                  (A) Subject to the prior and superior rights of the holders of
any shares of any series of Preferred Stock ranking prior and superior to the
Series A Junior Participating Preferred Stock with respect to dividends, the
holders of shares of Series A Junior Participating Preferred Stock in preference
to the holders of shares of Common Stock, par value $.01 per share (the "Common
Stock"), of the Company and any other junior stock, shall be entitled to
receive, when, as and if declared by the Board of Directors out of funds legally
available for the purpose, quarterly dividends payable in cash on the first day
of January, April, July, and October in each year (each such date being referred
to


                                       7
<PAGE>   9


herein as a "Quarterly Dividend Payment Date"), commencing on the first
Quarterly Dividend Payment Date after the first issuance of a share or fraction
of a share of Series A Junior Participating Preferred Stock in an amount per
share (rounded to the nearest cent) equal to the greater of (a) $25, or (b)
subject to the provision for adjustment hereinafter set forth, 100 times the
aggregate per share amount of all cash dividends, and 100 times the aggregate
per share amount (payable in kind) of all non-cash dividends or other
distributions other than a dividend payable in shares of Common Stock or a
subdivision of the outstanding shares of Common Stock (by reclassification or
otherwise), declared on the Common Stock since the immediately preceding
Quarterly Dividend Payment Date, or, with respect to the first Quarterly
Dividend Payment Date, since the first issuance of any share or fraction of a
share of Series A Junior Participating Preferred Stock. In the event the Company
shall at any time after December 16, 1998 (the "Rights Declaration Date") (i)
declare any dividend on Common Stock payable in shares of Common Stock, (ii)
subdivide the outstanding Common Stock, or (iii) combine the outstanding Common
Stock into a smaller number of shares, then in each such case the amount to
which holders of shares of Series A Junior Participating Preferred Stock were
entitled immediately prior to such event under clause (b) of the preceding
sentence shall be adjusted by multiplying such amount by a fraction the
numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

                  (B) The Company shall declare a dividend or distribution on
the Series A Junior Participating Preferred Stock as provided in paragraph (A)
above immediately after it declares a dividend or distribution on the Common
Stock (other than a dividend payable in shares of Common Stock); provided that,
in the event no dividend or distribution shall have been declared on the Common
Stock during the period between any Quarterly Dividend Payment Date and the next
subsequent Quarterly Dividend Payment Date, a dividend of $25 per share on the
Series A Junior Participating Preferred Stock shall nevertheless be payable on
such subsequent Quarterly Dividend Payment Date.

                  (C) Dividends shall begin to accrue and be cumulative on
outstanding shares of Series A Junior Participating Preferred Stock from the
Quarterly Dividend Payment Date next preceding the date of issue of such shares
of Series A Junior Participating Preferred Stock unless the date of issue of
such shares is prior to the record date for the first Quarterly Dividend Payment
Date, in which case dividends on such shares shall begin to accrue from the date
of issue of such shares, or unless the date of issue is a Quarterly Dividend
Payment Date or is a date after the record date for the determination of holders
of shares of Series A Junior Participating Preferred Stock entitled to receive a
quarterly dividend and before such Quarterly Dividend Payment Date in either of
which events such dividends shall begin to accrue and be cumulative from such
Quarterly Dividend Payment Date. Accrued but unpaid dividends shall not bear
interest. Dividends paid on the shares of Series A Junior Participating
Preferred Stock in an amount less than the total amount of such dividends at the
time accrued and payable on such shares shall be allocated pro rata on a
share-by-share basis among all such shares at the time outstanding. The Board of
Directors may fix a record date for the determination of holders of shares of
Series A Junior Participating Preferred Stock entitled to receive payment of a
dividend or distribution declared thereon, which record date shall be no more
than 60 days prior to the date fixed for the payment thereof.

             Section 3. Voting Rights. The holders of shares of Series A Junior
Participating Preferred Stock shall have the following voting rights:

             (A) Subject to the provision for adjustment hereinafter set forth,
each share of Series A Junior Participating Preferred Stock shall entitle the
holder thereof to 100 votes on all matters 


                                       8
<PAGE>   10


submitted to a vote of the stockholders of the Company. In the event the Company
shall at any time after the Rights Declaration Date (i) declare any dividend on
Common Stock payable in shares of Common Stock, (ii) subdivide the outstanding
Common Stock, or (iii) combine the outstanding Common Stock into a smaller
number of shares, then in each such case the number of votes per share to which
holders of shares of Series A Junior Participating Preferred Stock were entitled
immediately prior to such event shall be adjusted by multiplying such number by
a fraction the numerator of which is the number of shares of Common Stock
outstanding immediately after such event and the denominator of which is the
number of shares of Common Stock that were outstanding immediately prior to such
event.

             (B) Except as otherwise provided herein or by law, the holders of
shares of Series A Junior Participating Preferred Stock and the holders of
shares of Common Stock shall vote together as one class on all matters submitted
to a vote of shareholders of the Company.

             (C) (i) If at any time dividends on any Series A Junior
Participating Preferred Stock shall be in arrears in an amount equal to six (6)
quarterly dividends thereon, the occurrence of such contingency shall mark the
beginning of a period (herein called a "default period") which shall extend
until such time when all accrued and unpaid dividends for all previous quarterly
dividend periods and for the current quarterly dividend period on all shares of
Series A Junior Participating Preferred Stock then outstanding shall have been
declared and paid or set apart for payment. During each default period, all
holders of Preferred Stock (including holders of the Series A Junior
Participating Preferred Stock) with dividends in arrears in an amount equal to
six (6) quarterly dividends thereon, voting as a class, irrespective of series,
shall have the right to elect two (2) Directors.

             (ii) During any default period, such voting right of the holders of
             Series A Junior Participating Preferred Stock may be exercised
             initially at a special meeting called pursuant to subparagraph
             (iii) of this Section 3(C) or at any annual meeting of
             shareholders, and thereafter at annual meetings of stockholders,
             provided that neither such voting right nor the right of the
             holders of any other series of Preferred Stock, if any, to increase
             in certain cases, the authorized number of Directors shall be
             exercised unless the holders of ten percent (10%) in number of
             shares of Preferred Stock outstanding shall be present in person or
             by proxy. The absence of a quorum of the holders of Common Stock
             shall not affect the exercise by the holders of Preferred Stock of
             such voting right. At any meeting at which the holders of Preferred
             Stock shall exercise such voting right initially during an existing
             default period, they shall have the right, voting as a class, to
             elect Directors to fill such vacancies, if any, in the Board of
             Directors as may then exist up to two (2) Directors or, if such
             right is exercised at an annual meeting, to elect two (2)
             Directors. If the number which may be so elected at any special
             meeting does not amount to the required number, the holders of the
             Preferred Stock shall have the right to make such increase in the
             number of Directors as shall be necessary to permit the election by
             them of the required number. After the holders of the Preferred
             Stock shall have exercised their right to elect Directors in any
             default period and during the continuance of such period, the
             number of Directors shall not be increased or decreased except by
             vote of the holders of Preferred Stock as herein provided or
             pursuant to the rights of any equity securities ranking senior to
             or pari passu with the Series A Junior Participating Preferred
             Stock.

             (iii) Unless the holders of Preferred Stock shall, during an
             existing default period, have previously exercised their right to
             elect Directors, the Board of Directors may order, or any
             stockholder or stockholders owning in the aggregate not less than
             ten percent (10%) of the total number of shares of Preferred Stock
             outstanding, irrespective of series, may request, the calling of a
             special meeting of the holders of Preferred Stock, which meeting
             shall thereupon be called by the Chairman of the Board or the
             President and Chief Executive Officer of the Company. Notice of
             such meeting and of any annual meeting at which holders of
             Preferred Stock are entitled to vote pursuant to this paragraph
             (C)(iii) shall be given to each holder of record of Preferred Stock
             by mailing a copy of such notice to him at his last address as the
             same appears on the books of the Company. Such meeting shall be
             called for a time not earlier than 10 days and not later than 60
             days after such order or request or in default of the calling of
             such meeting within 60 days after such order or request, such
             meeting may be called on similar notice by any stockholder or
             stockholders owning in the aggregate not less than ten percent
             (10%) of the total number of shares of Preferred Stock outstanding.
             Notwithstanding the provisions of this paragraph (C)(iii), no such
             special meeting shall be called during the period within 60 days
             immediately preceding the date fixed for the next annual meeting of
             the stockholders.

             (iv) In any default period, the holders of Common Stock, and other
             classes of stock of the Company if applicable, shall continue to be
             entitled to elect the whole number of Directors until the holders
             of Preferred Stock shall have exercised their right to elect two
             (2) Directors voting as a class, after the exercise of which right
             (x) the Directors so elected by the holders of Preferred Stock
             shall continue in office until their successors shall have been
             elected by such holders or until the expiration of the default
             period, and (y) any vacancy in the Board of Directors may (except
             as provided in paragraph (C)(ii) of this Section 3) be filled by
             vote of a majority of the remaining Directors theretofore elected
             by the holders of the class of stock which elected the Director
             whose office shall become vacant. References in this paragraph (C)
             to Directors elected by the holders of a particular class of stock
             shall include Directors elected by such Directors to fill vacancies
             as provided in clause (y) of the foregoing sentence.

             (v) Immediately upon the expiration of a default period, (x) the
             right of the holders of Preferred Stock as a class to elect
             Directors shall cease, (y) the term of any Directors elected by the
             holders of Preferred Stock as a class shall terminate, and (z) the
             number of Directors shall be such number as may be provided for in
             the Restated Certificate of Incorporation or By-laws irrespective
             of any increase made pursuant to the provisions of paragraph
             (C)(ii) of this Section 3 (such number being subject, however, to
             change thereafter in any manner provided by law or in the Restated
             Certificate of Incorporation or By-laws). Any vacancies in the
             Board of Directors effected by the provisions of clause (y) and (z)
             in the preceding sentence may be filled by a majority of the
             remaining Directors.

             (D) Except as set forth herein, holders of Series A Junior
Participating Preferred Stock shall have no special voting rights and their
consent shall not be required (except to the extent they are entitled to vote
with holders of Common Stock as set forth herein) for taking any corporate
action.

             Section 4.  Certain Restrictions.

             (A) Whenever quarterly dividends or other dividends or
distributions payable on the Series A Junior Participating Preferred Stock as
provided in Section 2 are in arrears, thereafter and until all accrued and
unpaid dividends and distributions, whether or not declared, on shares of Series
A Junior Participating Preferred Stock outstanding shall have been paid in full,
the Company shall not:

             (i) Declare or pay dividends on, make any other distributions on,
             or redeem or purchase or otherwise acquire for consideration any
             shares of stock ranking junior (either as to dividends or upon
             liquidation, dissolution or winding up) to the Series A Junior
             Participating Preferred Stock;

             (ii) Declare or pay dividends on or make any other distributions on
             any shares of stock ranking on a parity (either as to dividends or
             upon liquidation, dissolution or winding up) with the Series A
             Junior Participating Preferred Stock except dividends paid ratably
             on the Series A Junior Participating Preferred Stock and all such
             parity stock on which dividends are payable or in arrears in
             proportion to the total amounts to which the holders of all such
             shares are then entitled;

             (iii) Redeem or purchase or otherwise acquire for consideration
             shares of any stock ranking on a parity (either as to dividends or
             upon liquidation, dissolution or winding up) with the Series A
             Junior Participating Preferred Stock provided that the Company may
             at any time redeem, purchase or otherwise acquire shares of any
             such parity stock in exchange for shares of any stock of the
             Company ranking junior (either as to dividends or upon dissolution,
             liquidation or winding up) to the Series A Junior Participating
             Preferred Stock; or

             (iv) Purchase or otherwise acquire for consideration any shares of
             Series A Junior Participating Preferred Stock or any shares of
             stock ranking on a parity with the Series A Junior Participating
             Preferred Stock except in accordance with a purchase offer made in
             writing or by publication (as determined by the Board of Directors)
             to all holders of such shares upon such terms as the Board of
             Directors, after consideration of the respective annual dividend
             rates and other relative rights and preferences of the respective
             series and classes, shall determine in good faith will result in
             fair and equitable treatment among the respective series or
             classes.

             (B) The Company shall not permit any subsidiary of the Company to
purchase or otherwise acquire for consideration any shares of stock of the
Company unless the Company could, under paragraph (A) of this Section 4,
purchase or otherwise acquire such shares at such time and in such manner.

             Section 5. Reacquired Shares. Any shares of Series A Junior
Participating Preferred Stock purchased or otherwise acquired by the Company in
any manner whatsoever shall be retired and cancelled promptly after the
acquisition thereof. All such shares shall upon their cancellation become
authorized but unissued shares of Preferred Stock and may be reissued as part of
a new series of Preferred Stock to be created by resolution or resolutions of
the Board of Directors, subject to the conditions and restrictions on issuance
set forth herein.

             Section 6. Liquidation, Dissolution or Winding Up.

             (A) Upon any liquidation (voluntary or otherwise), dissolution or
winding up of the Company, no distribution shall be made to the holders of
shares of stock ranking junior (either as to dividends or upon liquidation,
dissolution or winding up) to the Series A Junior Participating Preferred Stock
unless, prior thereto, the holders of shares of Series A Junior Participating
Preferred Stock shall have received per share, the greater of 100 times $200 or
100 times the payment made per share of Common Stock, plus an amount equal to
accrued and unpaid dividends and distributions thereon, whether or not declared,
to the date of such payment (the "Series A Liquidation Preference"). Following
the payment of the full amount of the Series A Liquidation Preference, no
additional distributions shall be made to the holders of shares of Series A
Junior Participating Preferred Stock unless, prior thereto, the holders of
shares of Common Stock shall have received an amount per share (the "Common
Adjustment") equal to the quotient obtained by dividing (i) the Series A
Liquidation Preference by (ii) 100 (as appropriately adjusted as set forth in
subparagraph C below to reflect such events as stock splits, stock dividends and
recapitalizations with respect to the Common Stock) (such number in clause (ii),
the "Adjustment Number"). Following the payment of the full amount of the Series
A Liquidation Preference and the Common Adjustment in respect of all outstanding
shares of Series A Junior Participating Preferred Stock and Common Stock,
respectively, holders of Series A Junior Participating Preferred Stock and
holders of shares of Common Stock shall receive their ratable and proportionate
share of the remaining assets to be distributed in the ratio of the Adjustment
Number to 1 with respect to such Preferred Stock and Common Stock, on a per
share basis, respectively.

             (B) In the event there are not sufficient assets available to
permit payment in full of the Series A Liquidation Preference and the
liquidation preferences of all other series of Preferred Stock, if any, which
rank on a parity with the Series A Junior Participating Preferred Stock then
such remaining assets shall be distributed ratably to the holders of such parity
shares in proportion to their respective liquidation preferences. In the event
there are not sufficient assets available to permit payment in full of the
Common Adjustment, then such remaining assets shall be distributed ratably to
the holders of Common Stock.

             (C) In the event the Company shall at any time after the Rights
Declaration Date (i) declare any dividend on Common Stock payable in shares of
Common Stock, (ii) subdivide the outstanding Common Stock, or (iii) combine the
outstanding Common Stock into a smaller number of shares, then in each such case
the Adjustment Number in effect immediately prior to such event shall be
adjusted by multiplying such Adjustment Number by a fraction the numerator of
which is the number of shares of Common Stock outstanding immediately after such
event and the denominator of which is the number of shares of Common Stock that
were outstanding immediately prior to such event.

             Section 7. Consolidation, Merger, etc. If the Company shall enter
into any consolidation, merger, combination or other transaction in which the
shares of Common Stock are exchanged for or changed into other stock or
securities, cash and/or any other property then in any such event the shares of
Series A Junior Participating Preferred Stock shall at the same time be
similarly exchanged or changed in an amount per share (subject to the provision
for adjustment hereinafter set forth) equal to 100 times the aggregate amount of
stock, securities, cash and/or any other property (payable in kind), as the case
may be, into which or for which each share of Common Stock is changed or
exchanged. In the event the Company shall at any time after the Rights
Declaration Date (i) declare any dividend on Common Stock payable in shares of
Common Stock, (ii) subdivide the outstanding Common Stock, or (iii) combine the
outstanding Common Stock into a smaller number of shares, then 


                                       12
<PAGE>   14


in each such case the amount set forth in the preceding sentence with respect to
the exchange or change of shares of Series A Junior Participating Preferred
Stock shall be adjusted by multiplying such amount by a fraction the numerator
of which is the number of shares of Common Stock outstanding immediately after
such event and the denominator of which is the number of shares of Common Stock
that are outstanding immediately prior to such event.

             Section 8. Redemption. The shares of Series A Junior Participating
Preferred Stock shall not be redeemable.

             Section 9. Ranking. The Series A Junior Participating Preferred
Stock shall rank junior to all other series of the Company's Preferred Stock as
to the payment of dividends and the distribution of assets, unless the terms of
any such series shall provide otherwise.

             Section 10. Fractional Shares. Series A Junior Participating
Preferred Stock may be issued in fractions of a share which shall entitle the
holder, in proportion to such holder's fractional shares, to exercise voting
rights, receive dividends, participate in distributions and to have the benefit
of all other rights of holders of Series A Junior Participating Preferred Stock.

         SECTION 3.        PLACE OF MEETINGS.

         The annual meeting of the stockholders of the corporation shall be held
at the general offices of the corporation in the City of Houston, State of
Texas, or at such other place in the United States as may be stated in the

notice of the meeting. (Amended December 6, 1995)

         SECTION 4.        NOTICE OF MEETINGS.

         4.1 Giving of Notice. Except as otherwise provided by statute, written
notice of each meeting of the stockholders, whether annual or special, shall be
given not less than ten nor more than sixty days before the date of the meeting
to each stockholder entitled to vote at such meeting. If mailed, notice shall be
given when deposited in the United States mails, postage prepaid, directed to
such stockholder at his or her address as it appears in the stock ledger of the
corporation. Each such notice shall state the place, date and hour of the
meeting, and, in the case of a special meeting, the purpose or purposes for
which the meeting is called.

         4.2 Notice of Adjourned Meetings. When a meeting is adjourned to
another time and place, notice of the adjourned meeting need not be given if the
time and place thereof are announced at the meeting at which the adjournment is
given. If the adjournment is for more than thirty days, or if after the

the adjourned meeting shall be given to each stockholder of record entitled to
vote at the meeting.

         4.3 Waiver of Notice.

         4.3.1 Whenever any notice is required to be given to any stockholder
under the provisions of these By-Laws, the Certificate of Incorporation or the
General Corporation Law of Delaware, a waiver thereof in writing, signed by the
person or persons entitled to such notice, whether before or after the time
stated therein, shall be deemed equivalent to the giving of such notice.

         4.3.2 The attendance of a stockholder at a meeting shall constitute a
waiver of notice of such meeting, except when a stockholder attends a meeting
for the express purpose of objecting, at the beginning of the meeting, to the
transaction of any business because the meeting is not lawfully called or
convened.

         SECTION 5.        FIXING OF RECORD DATE FOR DETERMINING STOCKHOLDERS.

         5.1 Meetings. For the purpose of determining stockholders entitled to
notice of or to vote at any meeting of stockholders or any adjournment thereof,
the Board may fix a record date, which record date shall not precede the date
upon which the resolution fixing the record date is adopted by the Board, and
which record date shall not be more than sixty nor less than ten days before the
date of such meeting. If no record date is fixed by the Board, the record date
for 


                                       2

<PAGE>   7

determining stockholders shall be at the close of business on the day next
preceding the day on which notice is given, or, if notice is waived, at the
close of business on the day next preceding the day on which the meeting is
held. A determination of stockholders of record entitled to notice of or to vote
at the meeting of stockholders shall apply to any adjournment of the meeting;
provided, however, that the Board may fix a new record date for the adjourned
meeting.

         5.2 Dividends, Distributions and Other Rights. For the purpose of
determining stockholders entitled to receive payment of any dividend or other
distribution or allotment of any rights or the stockholders entitled to exercise
any rights in respect of any change, conversion or exchange of stock, or for the
purpose of any other lawful action, the Board may fix a record date, which
record date shall not precede the date upon which the resolution fixing the
record date is adopted, and which record date shall be not more than sixty days
prior to such action. If no record date is fixed, the record date for
determining stockholders for any such purpose shall be at the close of business
on the day on which the Board adopts the resolution relating thereto.

         SECTION 6.        QUORUM.

         A majority of the outstanding shares of stock of the corporation
entitled to vote, present in person or represented by proxy, shall constitute a
quorum at a meeting of the stockholders; provided that where a separate vote by
a class or classes or by a series of a class is required, a majority of the
outstanding shares of such class or classes or of such series of a class,
present in person or represented by proxy at the meeting, shall constitute a
quorum entitled to take action with respect to the vote on that matter. If less
than a majority of the outstanding shares entitled to vote are represented at a
meeting, a majority of the shares so represented may adjourn the meeting from
time to time without further notice. If a quorum is present or represented at a
reconvened meeting following such an adjournment, any business may be transacted
that might have been transacted at the meeting as originally called. The
stockholders present at a duly organized meeting may continue to transact
business until adjournment, notwithstanding the withdrawal of enough
stockholders to leave less than a quorum.

         SECTION 7.        ORGANIZATION.

         At each meeting of the stockholders, the Chairman of the Board, or in
his or her absence such person as shall have been designated by the Board of
Directors, or in the absence of such designation a person elected by the holders
of a majority in number of shares of stock present in person or represented by
proxy and entitled to vote, shall act as Chairman of the meeting.

         The Secretary, or in his or her absence or in the event he or she shall
be presiding over the meeting in accordance with the provisions of this Section,
an Assistant Secretary or, in the absence of the Secretary and all of the
Assistant Secretaries, any person appointed by the Chairman of the meeting,
shall act as Secretary of the meeting.

         SECTION 8.        VOTING.

         8.1 Generally. Unless otherwise provided in the Certificate of
Incorporation or a resolution of the Board of Directors creating a series of
stock, at each meeting of the stockholders, each holder of shares of any series
or class of stock entitled to vote at such meeting shall be entitled to one vote
for each share of stock having voting power in respect of each matter upon which
a vote is to be taken, standing in his or her name on the stock ledger of the
corporation on the record date fixed as provided in these By-Laws for
determining the stockholders entitled to vote at such meeting. In all matters
other than the election of Directors, if a quorum is present, the affirmative
vote of the majority of the shares present in person or represented by proxy at
the meeting and entitled to vote on the subject matter shall be the act of the
stockholders, unless the vote of a greater number is required by these By-Laws,
the Certificate of Incorporation or the General Corporation Law of Delaware.
Where a separate vote by a class or classes or by a series of a class is
required, if a quorum is present, the affirmative vote of the majority of shares
of such class or classes or series of a class present in person or represented
by proxy at the meeting shall be the act of such class or classes or series of a
class.

         8.2 Voting for Directors. At each election of Directors the voting
shall be by ballot. Directors shall be elected by a plurality of the votes of
the shares present in person or represented by proxy at the meeting and entitled
to vote on the election of Directors.

         8.3 Shares Held or Controlled by the Corporation. Shares of its own
capital stock belonging to the corporation, or to another corporation if a
majority of the shares entitled to vote in the election of directors of such
other corporation is held by the corporation, shall neither be entitled to vote
nor counted for quorum purposes.

         8.4 Proxies. A stockholder may vote by proxy executed in writing by the
stockholder or by his or her attorney-in-fact. Alternatively, a stockholder may
vote by proxy by means of electronic transmission, including, but not limited
to, electronic mail, telephonic transmission or telegram; provided that any such
means of electronic transmission must set forth information from which it can be
determined that such electronic transmission was authorized by the stockholder.
Such written or electronically transmitted proxy shall be filed with the
Secretary of the corporation before or at the time of the meeting. A proxy shall
become invalid three years after the date of its execution, unless otherwise
provided in the proxy. A proxy with respect to a specified meeting shall entitle
the holder thereof to vote at any reconvened meeting following adjournment of
such meeting but shall not be valid after the final adjournment thereof.
(Amended July 8, 1998)

         SECTION 9.        INSPECTORS.

         Prior to each meeting of stockholders, the Board of Directors shall
appoint one or more Inspectors who are not directors, candidates for directors
or officers of the corporation, who shall receive and determine the validity of
proxies and the qualifications of voters, and receive, inspect, count and report
to the meeting in writing the votes cast on all matters submitted to a vote at
such meeting. In case of failure of the Board of Directors to make such
appointments or 



                                       4

<PAGE>   9

in case of failure of any Inspector so appointed to act, the Chairman of the
Board shall make such appointment or fill such vacancies. Each Inspector,
immediately before entering upon his or her duties, shall subscribe to an oath
or affirmation faithfully to execute the duties of Inspector at such meeting
with strict impartiality and according to the best of his or her ability.
(Amended July 8, 1998)

         SECTION 10.       LIST OF STOCKHOLDERS.

         The Secretary or other officer or agent having charge of the stock
ledger of the corporation shall prepare and make, at least ten days before every
meeting of stockholders, a complete list of the stockholders entitled to vote at
said meeting, arranged in alphabetical order and showing the address of each
stockholder and the number of shares of each class and series registered in the
name of each such stockholder. Such list shall be open to the examination of any
stockholder, for any purpose germane to the meeting, during ordinary business
hours, for a period of at least ten days prior to the meeting, either at a place
within the city where the meeting is to be held, which place shall be specified
in the notice of the meeting, or, if not so specified, at the place where the
meeting is to be held. Such list shall also be produced and kept at the time and
place of the meeting during the whole time thereof, and may be inspected by any
stockholder who is present. The stock ledger shall be the only evidence as to
who are the stockholders entitled to examine the stock ledger, the list required
by this section, or the books of the corporation, or to vote in person or by
proxy at any such meeting.

         SECTION 11.       NOTICE OF NOMINATIONS AND BUSINESS.

         11.1 Generally. Nominations of persons for election to the Board of
Directors and the proposal of business to be transacted by the stockholders may
be made at an annual meeting of the stockholders (a) pursuant to the
corporation's notice with respect to such meeting, (b) by or at the direction of
the Board or (c) by any stockholder of record of the corporation who was a
stockholder of record at the time of the giving of the notice provided for in
Section 11.2, who is entitled to vote at the meeting and who has complied with
the notice procedures set forth in this Section 11. A stockholder proceeding
under this Section 11 shall also comply with all applicable requirements of the
Securities Exchange Act of 1934, as amended (the "Exchange Act") and the rules
and regulations thereunder with respect to matters set forth in this Section 11.
Nothing in this Section 11 shall be deemed to affect any rights of stockholders
to request inclusion of proposals in the corporation's proxy statement pursuant
to Rule 14a-8 under the Exchange Act.

         11.2 Procedures.

         11.2.1 For nominations or other business to be properly brought before
an annual meeting of the stockholders by a stockholder pursuant to Section 11.1
(c), (1) the stockholder must have given timely notice thereof in writing to the
Secretary, (2) such business must be a proper matter for stockholder action
under the General Corporation Law of Delaware, (3) if the stockholder, or the
beneficial owner on whose behalf any such proposal or nomination is made, has
provided the corporation with a Solicitation Notice, as that term is defined in
subclause (c)(iii) of this Section 11.2, such stockholder or beneficial owner
must, in the case of a proposal, 



                                       5

<PAGE>   10

have delivered a proxy statement and form of proxy to holders of at least the
percentage of the corporation's voting shares required under applicable law to
carry any such proposal, or, in the case of a nomination or nominations, have
delivered a proxy statement and form of proxy to holders of a percentage of the
corporation's voting shares reasonably believed by such stockholder or
beneficial holder to be sufficient to elect the nominee or nominees proposed to
be nominated by such stockholder, and must, in either case, have included in
such materials the Solicitation Notice, and (4) if no Solicitation Notice
relating thereto has been timely provided pursuant to this Section 11, the
stockholder or beneficial owner proposing such business or nomination must not
have solicited a number of proxies sufficient to have required the delivery of
such a Solicitation Notice under this Section 11. To be timely, a stockholder's
notice shall be delivered to the Secretary at the principal executive offices of
the corporation in the City of Houston, State of Texas, not less than 60 days
prior to the first anniversary (the "Anniversary") of the date on which the
corporation first mailed its proxy materials for the preceding year's annual
meeting of the stockholders. However, that if the date of the annual meeting is
advanced more than 30 days prior to or delayed by more than 30 days after the
Anniversary of the preceding year's annual meeting, notice by the stockholder to
be timely must be so delivered not later than the close of business on the later
of (i) the 90th day prior to such annual meeting or (ii) the 10th day following
the day on which public announcement of the date of such meeting is first made.
Such stockholder's notice shall set forth (a) as to each person whom the
stockholder proposes to nominate for election or reelection as a director all
information relating to such person as would be required to be disclosed in
solicitations of proxies for the election of such nominees as directors pursuant
to Regulation 14A the Exchange Act, and such person's written consent to serve
as a director if elected; (b) as to any other business that the stockholder
proposes to bring before the annual meeting of the stockholders, a brief
description of such business, the reasons for conducting such business at the
annual meeting and any material interest in such business of such stockholder
and the beneficial owner, if any, on whose behalf the proposal is made; (c) as
to the stockholder giving the notice and the beneficial owner, if any, on whose
behalf the nomination or proposal is made, (i) the name and address of such
stockholder, as they appear on the corporation's books, and of such beneficial
owner, (ii) the class and number of shares of the corporation that are owned
beneficially and of record by such stockholder and such beneficial owner, and
(iii) whether either such stockholder or beneficial owner intends to deliver a
proxy statement and form of proxy to holders of, in the case of a proposal, at
least the percentage of the corporation's voting shares required under
applicable law to carry the proposal or, in the case of a nomination or
nominations, a sufficient number of holders of the corporation's voting shares
to elect such nominee or nominees (an affirmative statement of such intent, a
"Solicitation Notice").

         11.2.2 If the number of directors to be elected to the Board is
increased and there is no public announcement naming all of the nominees for
director or specifying the size of the increased Board made by the corporation
at least 70 days prior to the Anniversary, this Section 11.2.2 shall govern. In
this case a stockholder's notice required by these By-Laws shall also be
considered timely, but only with respect to nominees for any new positions
created by such increase, if it shall be delivered to the Secretary at the
principal executive offices of the corporation in the City of Houston, State of
Texas not later than the close of business on the 10th day following the day on
which such public announcement is first made by the corporation.

         11.2.3 Only such business shall be conducted at a special meeting of
the stockholders as shall have been brought before the special meeting pursuant
to the corporation's notice of meeting. Nominations of persons for election to
the Board may be made at a special meeting of the stockholders at which
directors are to be elected pursuant to the corporation's notice of meeting (a)
by or at the direction of the Board or (b) by any stockholder of record at the
time of giving of notice provided for in this paragraph, who shall be entitled
to vote at the special meeting and who complies with the notice procedures set
forth in this Section 11. Nominations by stockholders of persons for election to
the Board may be made at such a special meeting of the stockholder if the
stockholder's notice required by the second paragraph of this Section 11 shall
be delivered to the later than the close of business on the later of the 90th
day prior to such special meeting or the 10th day following the day on which
public announcement is first made of the date of the special meeting and of the
nominees proposed by the Board to be elected at such special meeting.

         11.2.4 Only persons nominated in accordance with the procedures set
forth in this Section 11 shall be eligible to serve as directors and only such
business shall be conducted at an annual meeting of the stockholders as shall
have been brought before the annual meeting in accordance with the procedures
set forth in this Section. The Chairman of the meeting shall have the power and
the duty to determine whether a nomination or any business proposed to be
brought before the annual meeting has been made in accordance with the
procedures set forth in these By-Laws and, if any proposed nomination or
business is not in compliance with these By-Laws, to declare that such defective
proposed business or nomination shall not be presented for stockholder action at
the annual meeting and shall be disregarded.

         11.3 For purposes of this Section, "public announcement" shall mean
disclosure in a press release reported by the Dow Jones News Service, Associated
Press or a comparable national news service or in a document publicly filed by
the corporation with the Securities and Exchange Commission pursuant to Section
13, 14 or 15(d) of the Exchange Act. (Added January 13, 1999)

meeting of stockholders a Board of Directors shall be elected by the
stockholders for a term of one year. Each Director shall serve until his or her
successor is elected and shall qualify.

Directors.

         SECTION 3.        RESIGNATIONS.

         Any Director may resign at any time upon written notice to the
Secretary of the corporation. Such resignation shall take effect on the date of
receipt of such notice or at any later date specified therein; and the
acceptance of such resignation, unless required by the terms thereof, shall not
be necessary to make it effective. When one or more Directors shall resign
effective at a future date, a majority of the Directors then in office,
including those who have resigned, shall have power to fill such vacancy or
vacancies to take effect when such resignation or resignations shall become
effective.

         SECTION 4.        REMOVALS.

         Any Director may be removed, with cause, at any special meeting of the
stockholders called for that purpose, by the affirmative vote of the holders of
a majority in number of shares of the corporation entitled to vote for the
election of such Director, and the vacancy in the Board caused by any such
removal may be filled by the stockholders at such a meeting.

         SECTION 5.        PLACE OF MEETINGS; BOOKS AND RECORDS.

         The Board of Directors may hold its meetings, and have an office or
offices, at such place or places within or without the State of Delaware as the
Board from time to time may determine.

         The Board of Directors, subject to the provisions of applicable
statutes, may authorize the books and records of the corporation, and offices or
agencies for the issue, transfer and registration of the capital stock of the
corporation, to be kept at such place or places outside of the State of Delaware
as, from time to time, may be designated by the Board of Directors.

         SECTION 6.        ANNUAL MEETING OF THE BOARD.

         The first meeting of each newly elected Board of Directors, to be known
as the Annual Meeting of the Board, for the purpose of electing officers,
designating committees and the transaction of such other business as may come
before the Board, shall be held as soon as practicable after the adjournment of
the annual meeting of stockholders, and no notice of such meeting shall be
necessary to the newly elected Directors in order legally to constitute the
meeting, provided a quorum shall be present. In the event such meeting is not
held due to the absence of a quorum, the meeting may be held at such time and
place as shall be specified in a 


                                       8

thereof. Whenever any notice is required to be given to any Director under the
provisions of these By-Laws, the Certificate of Incorporation or the General
Corporation Law of Delaware, a waiver thereof in writing, signed by the person
or persons entitled to such notice, whether before or after the time stated
therein, shall be deemed equivalent to the giving of such notice. Neither the
business to be transacted at, nor the purpose of, any regular or special meeting
of the Board or any committee appointed by the Board need be specified in the
waiver of notice of such meeting. Attendance of a Director at any meeting shall
constitute a waiver of notice of such meeting except when a Director attends a
meeting for the express purpose of objecting to the transaction of any business
because the meeting was not lawfully called or convened.

amendment), or by other applicable law as then in effect, against all expense,
liability and loss (including attorneys' fees, judgments, fines, ERISA excise
taxes or penalties and amounts to be paid in settlement) actually and reasonably
incurred or suffered by such indemnitee in connection therewith and such
indemnification shall continue as to an indemnitee who has ceased to be a
director, officer, employee or agent and shall inure to the benefit of the
indemnitee's heirs, executors and administrators, provided, however, that except
as provided in Section 2 of this Article with respect to proceedings seeking to
enforce rights to indemnification, the corporation shall indemnify any such
indemnitee seeking indemnification in connection with a proceeding (or part
thereof) initiated by such indemnitee only if such proceeding (or part thereof)
was authorized by the Board of Directors of the corporation. The right to
indemnification conferred in this Section shall be a contract right and shall
include the right to be paid by the corporation the expenses incurred in
defending any such proceeding in advance of its final disposition (hereinafter
an "advancement of expenses"); provided, however, that, if the Delaware General
Corporation Law requires, an advancement of expenses incurred by an indemnitee
in his or her capacity as a Director or officer (and not in any other capacity
in which service was or is rendered by such indemnitee while a Director or
officer, including, without limitation, service to an employee benefit plan)
shall be made only upon delivery to the corporation of an undertaking, by or on
behalf of such indemnitee, to repay all amounts so advanced if it shall
ultimately be determined that such indemnitee is not entitled to be indemnified
under this Section 1, or otherwise.

         SECTION 2.        RIGHT OF INDEMNITEE TO BRING SUIT.

         If a claim under Section 1 of this Article is not paid in full by the
corporation within sixty days after a written claim has been received by the
corporation, except in the case of a claim for an advancement of expenses, in
which case the applicable period shall be twenty days, the indemnitee may at any
time thereafter bring suit against the corporation to recover the unpaid amount
of the claim and, to the extent successful in whole or in part, the indemnitee
shall be entitled to be paid also the expense of prosecuting such suit. The
indemnitee shall be presumed to be entitled to indemnification under this
Article upon submission of a written claim (and, in an action brought to enforce
a claim for an advancement of expenses, where the required undertaking, if any
is required, has been tendered to the corporation), and thereafter the
corporation shall have the burden of proof to overcome the presumption that the
indemnitee is not so entitled. Neither the failure of the corporation (including
its Board of Directors, independent legal counsel, or its stockholders) to have
made a determination prior to the commencement of such suit that indemnification
of the indemnitee is proper in the circumstances nor an actual determination by
the corporation (including its Board of Directors, independent legal counsel or
its stockholders) that the indemnitee is not entitled to indemnification shall
be a defense to the suit or create a presumption that the indemnitee is not so
entitled.

         SECTION 3.        NONEXCLUSIVITY OF RIGHTS.

         The rights to indemnification and to the advancement of expenses
conferred in this Article shall not be exclusive of any other right which any
person may have or hereafter acquire under any statute, provision of the
Certificate of Incorporation, By-Law, agreement, vote of stockholders or
disinterested Directors or otherwise.

         SECTION 4.        INSURANCE, CONTRACTS AND FUNDING.

         The corporation may maintain insurance, at its expense, to protect
itself and any Director, officer, employee or agent of the corporation or
another corporation, partnership, joint venture, trust or other enterprise
against any expense, liability or loss, whether or not the corporation would
have the power to indemnify such person against such expense, liability or loss
under the Delaware General Corporation Law. The corporation may enter into
contracts with any indemnitee in furtherance of the provisions of this Article
and may create a trust fund, grant a security interest or use other means
(including, without limitation, a letter of credit) to ensure the payment of
such amounts as may be necessary to effect indemnification as provided in this
Article.

         SECTION 5.        DEFINITION OF DIRECTOR AND OFFICER.

         Any person who is or was serving as a Director or officer of a wholly
owned subsidiary of the corporation shall be deemed, for purposes of this
Article only, to be a Director or officer of the corporation entitled to
indemnification under this Article.

         SECTION 6.        INDEMNIFICATION OF EMPLOYEES AND AGENTS OF THE 
                           CORPORATION.

         The corporation may, by action of the Board of Directors from time to
time, grant rights to indemnification and advancement of expenses to employees
and agents of the corporation with the same scope and effect as the provisions
of this Article with respect to the indemnification and advancement of expenses
of Directors and officers of the corporation.

                                   ARTICLE XI

                       CHECKS, DRAFTS, BANK ACCOUNTS, ETC.

         SECTION 1.        CHECKS, DRAFTS, ETC.; LOANS.

         All checks, drafts or other orders for the payment of money, notes or
other evidences of indebtedness issued in the name of the corporation shall be
signed by such officer or officers, agent or agents of the corporation and in
such manner as shall, from time to time, be determined by resolution of the
Board of Directors. No loans shall be contracted on behalf of the corporation
unless authorized by the Board of Directors. Such authority may be general or
confined to specific circumstances. (Amended July 7, 1992)

         SECTION 2.        DEPOSITS.

         All funds of the corporation shall be deposited, from time to time, to
the credit of the corporation in such banks, trust companies or other
depositories as the Board of Directors may select, or as may be selected by any
officer or officers, agent or agents of the corporation to whom such power may,
from time to time, be delegated by the Board of Directors; and for the purpose
of such deposit, the Chairman of the Board, the President, any Vice President,
the Treasurer or any Assistant Treasurer, the Secretary or any Assistant
Secretary, or any other officer or agent to whom such power may be delegated by
the Board of Directors, may endorse, assign and deliver checks, drafts and other
order for the payment of money which are payable to the order of the
corporation.

                                   AMENDMENTS

         These By-Laws may be altered or repealed and new By-Laws may be made by
the affirmative vote, at any meeting of the Board, of a majority of the whole
Board of Directors, subject to the rights of the stockholders of the corporation
to amend or repeal By-Laws made or amended by the Board of Directors by the
affirmative vote of the holders of record of a majority in number of shares of
the outstanding stock of the corporation present or represented at any meeting
of the stockholders and entitled to vote thereon, provided that notice of the
proposed action be included in the notice of such meeting.

                        AMOUNTS AND TERMS OF THE ADVANCES

         SECTION 2.1. (a Revolving A Advances. Each Lender severally agrees, on
the terms and conditions hereinafter set forth, to make A Advances to the
Borrower from time to time on any Business Day during the period from the
Effective Date to and including the Termination Date in an aggregate amount not
to exceed at any time outstanding the amount set forth opposite such Lender's
name on the signature pages hereof under the caption "COMMITMENTS", or, if such
Lender has entered into any Assignment and Acceptance or Commitment Increase
Agreement or a New Lender Agreement, set forth for such Lender in the Register
maintained by the Administrative Agent pursuant to Section 8.07(c), as such
amount may be reduced pursuant to Section 2.04 (such Lender's "COMMITMENT"),
provided that the aggregate amount of the Commitments of the Lenders shall be
deemed used from time to time to the extent of the aggregate amount of the B
Advances then outstanding and such deemed use of the aggregate amount of such
Commitments shall be applied to all the Lenders ratably according to their
respective Commitments (such deemed use of the aggregate amount of the
Commitments being a "B REDUCTION"). Each A Borrowing consisting of Revolving A
Advances shall be in an aggregate amount of $10,000,000 in the case of an A
Borrowing comprised of Base Rate Advances and $25,000,000 in the case of an A
Borrowing comprised of Eurodollar Rate Advances, or, in either case an integral
multiple of $1,000,000 in excess thereof (or, in the case of an A Borrowing of
Base Rate Advances, the aggregate unused Commitments, if less) and shall consist
of A Advances of the same Type made on the same day by the Lenders ratably
according to their respective Commitments. Within the limits of each Lender's
Commitment, the Borrower may make more than one Borrowing on any Business Day
and may borrow, prepay pursuant to Section 2.10, and reborrow under this Section
2.01(a).

         (b) Term A Advances. Each Lender severally agrees, at the option of the
Borrower and on the terms and conditions set forth in this Agreement, to make an
A Advance to the Borrower on the Stated Termination Date in an aggregate amount
up to but not exceeding the amount of its Commitment. Each A Borrowing
consisting

                                       22

<PAGE>   27


of Term A Advances shall be in an aggregate amount of $10,000,000 in the case of
an A Borrowing comprised of Base Rate Advances and $25,000,000 in the case of an
A Borrowing comprised of Eurodollar Rate Advances, or, in either case an
integral multiple of $1,000,000 in excess thereof and shall consist of A
Advances of the same Type made on the Stated Termination Date by the Lenders
ratably according to their respective Commitments.

         SECTION 2.2.  Making the A Advances.

         (a Each A Borrowing shall be made on notice by the Borrower to the
Administrative Agent (a "NOTICE OF A BORROWING") received by the Administrative
Agent, (i) in the case of a proposed A Borrowing comprised of Base Rate
Advances, not later than 10:00 A.M. (New York City time) on the Business Day of
such proposed A Borrowing, and (ii) in the case of a proposed A Borrowing
comprised of Eurodollar Rate Advances, not later than 12:00 noon (New York City
time) on the third Business Day prior to the date of such proposed A Borrowing.
Each Notice of A Borrowing shall be by telecopy, telefax or other
teletransmission or by telephone (and if by telephone, confirmed promptly by
telecopier, telefax or other teletransmission), in substantially the form of
Exhibit B hereto, specifying therein the requested (w) date of such A Borrowing,
(x) Type of A Advances comprising such A Borrowing and, additionally, whether
such A Borrowing consists of Revolving A Advances or Term A Advances, (y)
aggregate amount of such A Borrowing, and (z) in the case of an A Borrowing
comprised of Eurodollar Rate Advances, the initial Interest Period for each such
A Advance. Each Lender shall, before 1:00 p.m. (New York City time) on the date
of such A Borrowing, make available for the account of its Applicable Lending
Office to the Administrative Agent in care of The Chase Manhattan Bank, Agency
Services, One Chase Manhattan Plaza, 8th Floor, New York, NY 10081, Attention:
Muniram Appanna, Reference: Burlington Resources Inc., or at such other location
designated by notice from the Administrative Agent to the Lenders pursuant to
Section 8.02, in same day funds, such Lender's ratable portion of such

                                       23

<PAGE>   28


A Borrowing. Immediately after the Administrative Agent's receipt of such funds
and upon fulfillment of the applicable conditions set forth in Article 3, the
Administrative Agent will make such funds available to the Borrower at The Chase
Manhattan Bank, One Chase Manhattan Plaza, 8th Floor, New York, NY 10081, or at
any account of the Borrower maintained by the Administrative Agent (or any
successor Administrative Agent) designated by the Borrower and agreed to by the
Administrative Agent (or such successor Administrative Agent), in same day
funds.

         (b Each Notice of A Borrowing shall be irrevocable and binding on the
Borrower. In the case of any A Borrowing which the related Notice of A Borrowing
specified is to be comprised of Eurodollar Rate Advances, if such A Advances are
not made as a result of any failure to fulfill on or before the date specified
for such A Borrowing the applicable conditions set forth in Article 3, the
Borrower shall indemnify each Lender against any loss, cost or expense incurred
by such Lender as a result of such failure, including any loss, cost or expense
incurred by reason of the liquidation or reemployment of deposits or other funds
acquired by such Lender to fund the A Advance to be made by such Lender as part
of such A Borrowing.

         (c If any Lender makes a Term A Advance to the Borrower hereunder on a
day on which the Borrower is to repay all or any part of an outstanding
Revolving A Advance from such Lender, such Lender shall apply the proceeds of
its Term A Advance to make such repayment and only an amount equal to the
difference (if any) between the amount being borrowed and the amount being
repaid shall be made available by such Lender to the Administrative Agent as
provided in subsection 2.02(a), or remitted by the Borrower to the
Administrative Agent as provided in Section 2.14, as the case may be.

         (d Unless the Administrative Agent shall have received notice from a
Lender prior to the date of any A Borrowing that such Lender will not make
available to the Administrative Agent such Lender's ratable portion of such A
Borrowing, the Administrative Agent may assume that such Lender has made such
portion available to the Administrative Agent on the date of such

                                       24

<PAGE>   29


A Borrowing in accordance with subsections (a) and (c) of this Section 2.02 and
the Administrative Agent may, in reliance upon such assumption, make available
to the Borrower on such date a corresponding amount. If and to the extent such
Lender shall not have so made such ratable portion available to the
Administrative Agent, such Lender and the Borrower severally agree to repay to
the Administrative Agent forthwith on demand such corresponding amount together
with interest thereon, for each day from the date such amount is made available
to the Borrower until the date such amount is repaid to the Administrative
Agent, at the Effective Federal Funds Rate for such day. If such Lender shall
repay to the Administrative Agent such corresponding amount, such amount so
repaid shall constitute such Lender's A Advance to the Borrower as part of such
A Borrowing for purposes of this Agreement.

         (e The failure of any Lender to make the A Advance to be made by it as
part of any A Borrowing shall not relieve any other Lender of its obligation, if
any, hereunder to make its A Advance on the date of such A Borrowing, but no
Lender shall be responsible for the failure of any other Lender to make the A
Advance to be made by such other Lender on the date of any A Borrowing.

         SECTION 2.3.  Fees.

         (a FACILITY FEE. The Borrower agrees to pay to the Administrative Agent
for the account of each Lender (other than a Designated Bidder) a facility fee
on the average daily amount of such Lender's Commitment, whether or not used or
deemed used, from the Effective Date in the case of each Initial Lender and from
the effective date specified in the Assignment and Acceptance or Commitment
Increase Agreement pursuant to which it became a Lender in the case of each
other Lender, in each case until the Termination Date, payable quarterly in
arrears on the last day of each March, June, September and December during the
term of such Lender's Commitment and on the Termination Date, at a rate per
annum equal to the Facility Fee Percentage in effect from time to time.

         (b UTILIZATION FEE. The Borrower agrees to pay to the Administrative
Agent for the account of each

                                       25

<PAGE>   30


Lender a utilization fee of 0.25% per annum on the average daily amount of such
Lender's Advances during any period (each such period, a "Utilization Fee
Period") during the term of this Agreement commencing on the Effective Date or
on a subsequent January 1, April 1, July 1 or October 1 and ending in each case
on the earliest to occur of the next succeeding March 31, June 30, September 30
or December 31 and the Termination Date, if during such Utilization Fee Period
the average daily outstanding amount of all Advances was greater than 25% of the
average daily amount of all Commitments. If a utilization fee is owing in
respect of any Utilization Fee Period, such fee shall be payable on the last day
of such Utilization Fee Period. 

         (c AGENCY FEE. The Borrower agrees to pay to the Administrative Agent,
for its own account, such agency fees as may be separately agreed to in writing
by the Borrower and the Administrative Agent, such fees to be in the amounts and
payable on the dates as may be so agreed to.

         (d ARRANGEMENT FEE. The Borrower agrees to pay to the Administrative
Agent, for its own account, an arrangement fee in the amount and payable on the
date separately agreed to in writing by the Administrative Agent and the
Borrower.

         SECTION 2.4. Reduction of the Commitments. The Borrower shall have the
right, upon at least three Business Days' notice to the Administrative Agent, to
terminate in whole or reduce ratably in part the unused portions of the
Commitments of the Lenders (being the amount by which such Commitments exceed
the aggregate outstanding principal amount of all Advances), provided that each
partial reduction shall be in the aggregate amount of $20,000,000 or any whole
multiple of $1,000,000 in excess thereof.

         SECTION 2.5. Repayment of A Advances. (a) The Borrower shall repay to
each Lender on the Termination Date the aggregate principal amount of the
Revolving A Advances, together with accrued interest thereon, then owing to such
Lender.

         (b) The Borrower shall repay to each Lender on the Final Maturity Date
the aggregate principal amount of

                                       26

<PAGE>   31

the Term A Advances, together with accrued interest thereon, then owing to such
Lender.

         SECTION 2.6.  Interest on A Advances.

         (a ORDINARY INTEREST. The Borrower shall pay interest on the unpaid
principal amount of each A Advance owing to each Lender from the date of such A
Advance until such principal amount is due (whether at stated maturity, by
acceleration or otherwise), at the following rates:

                   (i BASE RATE ADVANCES. During such periods as such A Advance
         is a Base Rate Advance, a rate per annum equal at all times to the Base
         Rate in effect from time to time plus, in the case of any Term A
         Advance, as additional interest in lieu of the facility fee, the
         Facility Fee Percentage in effect from time to time, payable quarterly
         in arrears on the last day of each March, June, September and December
         during such periods and on the date such Base Rate Advance shall be
         Converted or due (whether at stated maturity, by acceleration or
         otherwise).

                  (ii EURODOLLAR RATE ADVANCES. During such periods as such A
         Advance is a Eurodollar Rate Advance, a rate per annum equal at all
         times during each Interest Period for such A Advance to the sum of the
         Eurodollar Rate for such Interest Period plus the Eurodollar Rate
         Margin in effect from time to time plus, in the case of any Term A
         Advance, as additional interest in lieu of the facility fee, the
         Facility Fee Percentage in effect from time to time, payable on the
         last day of each such Interest Period and, if any such Interest Period
         has a duration of more than three months, on each day which occurs
         during such Interest Period every three months from the first day of
         such Interest Period and, if such A Advance is Converted into a Base
         Rate Advance on any date other than the last day of any Interest Period
         for such A Advance, on the date of such Conversion or, if later, the
         Business Day on which the Borrower shall have received at least one
         Business Day's prior notice from the Administrative Agent or the

                                       27

<PAGE>   32

         applicable Lender of the amount of unpaid interest accrued on such A
         Advance to the date of such Conversion.

                 (iii ADDITIONAL INTEREST ON TERM A ADVANCES. In addition to
         amounts payable under clause (i) or (ii) above in respect of any Term A
         Advance, the Borrower shall pay to each Lender hereunder as additional
         interest an amount in lieu of the utilization fee equal to 0.25% per
         annum on the average daily amount of such Lender's Term A Advances
         during any period (each such period, an "Additional Interest Period")
         during the term of this Agreement commencing on the Termination Date or
         on a subsequent January 1, April 1, July 1 or October 1 and ending in
         each case on the earliest to occur of the next succeeding March 31,
         June 30, September 30 or December 31 and the Final Maturity Date, if
         during such Additional Interest Period the average daily outstanding
         amount of all Term A Advances was greater than 25% of the aggregate
         amount of all the Commitments on the Termination Date. If additional
         interest is owing in respect of any Additional Interest Period, such
         amount shall be payable on the last day of such Additional Interest
         Period.

         (b DEFAULT INTEREST. The Borrower shall pay interest on the unpaid
principal amount of each Advance that is not paid when due (whether at stated
maturity, by acceleration or otherwise) from the date on which such amount is
due until such amount is paid in full, payable on demand, at a rate per annum
equal at all times (i) from such due date to the last day of the then existing
Interest Period therefor, in the case of each Eurodollar Rate Advance, to 1% per
annum above the interest rate per annum required to be paid on such A Advance
immediately prior to the date on which such amount became due and (ii) from and
after the last day of the then existing Interest Period therefor, in the case of
each Eurodollar Rate Advance, and at all times in the case of each Base Rate
Advance or B Advance, to 1% per annum above the Base Rate in effect from time to
time.

<PAGE>   33


         SECTION 2.7. Additional Interest on Eurodollar Rate Advances. If any
Lender shall determine in good faith that reserves under regulations of the
Board of Governors of the Federal Reserve System are required to be maintained
by it in respect of, or a portion of its costs of maintaining reserves under
such regulations is properly attributable to, one or more of its Eurodollar Rate
Advances, the Borrower shall pay to such Lender additional interest on the
unpaid principal amount of each such Eurodollar Rate Advance payable on the same
day or days on which interest is payable on such A Advance, at an interest rate
per annum up to but not exceeding at all times during each Interest Period for
such A Advance the excess of (i) the rate obtained by dividing the Eurodollar
Rate for such Interest Period by a percentage equal to 100% minus the Eurodollar
Reserve Percentage, if any, for such Lender for such Interest Period over (ii)
the Eurodollar Rate for such Interest Period. Any Lender wishing to require
payment of such additional interest (x) shall so notify the Borrower and the
Administrative Agent, in which case such additional interest on the Eurodollar
Rate Advances of such Lender shall be payable to such Lender at the place
indicated in such notice with respect to each Interest Period commencing at
least five Business Days after the giving of such notice and (y) shall furnish
to the Borrower at least five Business Days prior to each date on which interest
is payable on the Eurodollar Rate Advances an officer's certificate setting
forth the amount to which such Lender is then entitled under this Section, which
certificate shall be conclusive and binding for all purposes, absent manifest
error.

         SECTION 2.8. Interest Rate Determination.

         (a Each Reference Bank agrees to furnish to the Administrative Agent
timely information for the purpose of determining each Eurodollar Rate. If any
one or more of the Reference Banks shall not furnish such timely information to
the Administrative Agent for the purpose of determining any such interest rate,
the Administrative Agent shall determine such interest rate

                                       29

<PAGE>   34


on the basis of timely information furnished by the remaining Reference Banks.

         (b The Administrative Agent shall give prompt notice to the Borrower
and the Lenders of the applicable interest rate determined by the Administrative
Agent for purposes of Section 2.06(a)(i) or (ii), and the applicable rate, if
any, furnished by each Reference Bank for the purpose of determining the
applicable interest rate under Section 2.06(a)(ii).

         (c If fewer than two Reference Banks furnish timely information to the
Administrative Agent for determining the Eurodollar Rate for any applicable A
Advances,

                   (i the Administrative Agent shall give the Borrower and each
         Lender prompt notice by telephone (confirmed in writing) that the
         interest rate cannot be determined for such applicable A Advances,

                  (ii each such A Advance that is a Eurodollar Rate Advance will
         automatically, on the last day of the then existing Interest Period
         therefor, Convert into a Base Rate Advance (or if such A Advance is
         then a Base Rate Advance, will continue as a Base Rate Advance), and

                 (iii the obligations of the Lenders to make, or to Convert A
         Advances into, Eurodollar Rate Advances, as the case may be, shall be
         suspended until the Administrative Agent shall notify the Borrower and
         the Lenders that the circumstances causing such suspension no longer
         exist.

         (d If, with respect to any Eurodollar Rate Advances, the Majority
Lenders determine and give notice to the Administrative Agent that as a result
of conditions in or generally affecting the relevant market, the rates of
interest determined on the basis of the Eurodollar Rate for any Interest Period
for such A Advances will not adequately reflect the cost to such Majority
Lenders of making, funding or maintaining their respective Eurodollar Rate
Advances for such Interest Period, the Administrative Agent shall forthwith so
notify the Borrower and the Lenders, whereupon,

                                       30

<PAGE>   35


                   (i each such Eurodollar Rate Advance will automatically, on
         the last day of the then existing Interest Period therefor, Convert
         into a Base Rate Advance, and

                  (ii the obligation of the Lenders to make, or to Convert A
         Advances into, Eurodollar Rate Advances shall be suspended until the
         Administrative Agent shall notify the Borrower and the Lenders that the
         circumstances causing such suspension no longer exist.

         (e If the Borrower shall fail to select the duration of any Interest
Period for any Eurodollar Rate Advances in accordance with the provisions
contained in the definition of "Interest Period" in Section 1.01, the
Administrative Agent will forthwith so notify the Borrower and the Lenders and
such Eurodollar Rate Advances will automatically, on the last day of the then
existing Interest Period therefor, Convert into Base Rate Advances.

         (f On the date on which the aggregate unpaid principal amount of A
Advances comprising any A Borrowing shall be reduced, by payment or prepayment
or otherwise, to less than $10,000,000, such A Advances shall, if they are
Eurodollar Rate Advances, automatically Convert into Base Rate Advances, and on
and after such date the right of the Borrower to Convert such A Advances into
Eurodollar Rate Advances shall terminate; provided, however, that if and so long
as each such A Advance shall be, or be elected to be Converted to, Eurodollar
Rate Advances having the same Interest Period as Eurodollar Rate Advances
comprising another A Borrowing or other A Borrowings, and the aggregate unpaid
principal amount of all such Eurodollar Rate Advances shall, or upon such
Conversion will, equal or exceed $20,000,000, the Borrower shall have the right
to continue all such Eurodollar Rate Advances as, or to Convert all such A
Advances into, Eurodollar Rate Advances having such Interest Period.

         SECTION 2.9. Voluntary Conversion of A Advances. The Borrower may on
any Business Day, upon notice given to the Administrative Agent, not later than
12:00 noon (New York City time) on the third Business Day prior to the date of
the proposed Conversion, and

                                       31

<PAGE>   36

subject to the provisions of Section 2.08, 2.11 and 2.13, Convert all A Advances
of one Type comprising the same A Borrowing into A Advances of the other Type;
provided, however, that any Conversion of any Eurodollar Rate Advances into Base
Rate Advances made on any day other than the last day of an Interest Period for
such Eurodollar Rate Advances shall be subject to the provisions of Section
8.04(b). Each such notice of a Conversion shall, within the restrictions
specified above, specify (i) the date of such Conversion, (ii) the A Advances to
be Converted, and (iii) if such Conversion is into Eurodollar Rate Advances, the
duration of the Interest Period for each such Eurodollar Rate Advance.

         SECTION 2.10. Prepayments. The Borrower may, upon (i) in the case of
Eurodollar Rate Advances, at least three Business Days notice or (ii) in the
case of Base Rate Advances, telephonic notice not later than 12:00 noon (New
York City time) on the date of prepayment, to the Administrative Agent which
specifies the proposed date and aggregate principal amount of the prepayment and
the Type of A Advances to be prepaid, and if such notice is given the Borrower
shall, prepay the outstanding principal amounts of the A Advances comprising the
same A Borrowing in whole or ratably in part, together with accrued interest to
the date of such prepayment on the amount prepaid; provided, however, that (x)
each partial prepayment shall be in an aggregate principal amount not less than
$10,000,000 or an integral multiple of $1,000,000 in excess thereof and (y) in
the event of any such prepayment of Eurodollar Rate Advances on any day other
than the last day of an Interest Period for such Eurodollar Rate Advances, the
Borrower shall be obligated to reimburse the Lenders in respect thereof pursuant
to, and to the extent required by, Section 8.04(b); provided, further, however,
that the Borrower will use its best efforts to give notice to the Administrative
Agent of the proposed prepayment of Base Rate Advances on the Business Day prior
to the date of such proposed prepayment.

         SECTION 2.11.  Increased Costs.

                                       32

<PAGE>   37


           (a If, due to either (i) the introduction after the Original
Effective Date of or any change after the Original Effective Date (including any
change by way of imposition or increase of reserve requirements or assessments
other than those referred to in the definition of "Eurodollar Reserve
Percentage" contained in Section 1.01) in or in the interpretation of any law or
regulation or (ii) the compliance with any guideline or request issued or made
after the Original Effective Date from or by any central bank or other
governmental authority (whether or not having the force of law), in each case
above other than those referred to in Section 2.12, there shall be any increase
in the cost to any Lender of agreeing to make, fund or maintain, or of making,
funding or maintaining, Eurodollar Rate Advances funded in the interbank
Eurodollar market, then the Borrower shall from time to time, upon demand by
such Lender (with a copy of such demand to the Administrative Agent), pay to the
Administrative Agent for the account of such Lender additional amounts
sufficient to reimburse such Lender for all such increased costs (except those
incurred more than 60 days prior to the date of such demand; for the purposes
hereof any cost or expense allocable to a period prior to the publication or
effective date of such an introduction, change, guideline or request shall be
deemed to be incurred on the later of such publication or effective date). Each
Lender agrees to use its best reasonable efforts promptly to notify the Borrower
of any event referred to in clause (i) or (ii) above, provided that the failure
to give such notice shall not affect the rights of any Lender under this Section
2.11(a) (except as otherwise expressly provided above in this Section 2.11(a)).
A certificate as to the amount of such increased cost, submitted to the Borrower
and the Administrative Agent by such Lender, shall be conclusive and binding for
all purposes, absent manifest error. After one or more Lenders have notified the
Borrower of any increased costs pursuant to this Section 2.11, the Borrower may
specify by notice to the Administrative Agent and the affected Lenders that,
after the date of such notice whenever the election of a Eurodollar Rate Advance
by the

                                       33

<PAGE>   38


Borrower for an Interest Period or portion thereof would give rise to such
increased costs, such election shall not apply to the A Advances of such Lender
or Lenders during such Interest Period or portion thereof, and, in lieu thereof,
such A Advances shall during such Interest Period or portion thereof be Base
Rate Advances. Each Lender agrees to use its best reasonable efforts (including
a reasonable effort to change its Applicable Lending Office or to transfer its
affected A Advances to an Affiliate of such Lender) to avoid, or minimize the
amount of, any demand for payment from the Borrower under this Section 2.11,
provided that such avoidance would not, in the reasonable judgment of such
Lender, be otherwise disadvantageous to such Lender.

         (b In the event that any Lender shall change its Eurodollar Lending
Office and such change results (at the time of such change) in increased costs
to such Lender, the Borrower shall not be liable to such Lender for such
increased costs incurred by such Lender to the extent, but only to the extent,
that such increased costs shall exceed the increased costs which such Lender
would have incurred if the Eurodollar Lending Office of such Lender had not been
so changed, but, subject to subsection (a) of this Section 2.11 and to Section
2.13, nothing herein shall require any Lender to change its Eurodollar Lending
Office for any reason.

         SECTION 2.12. Increased Capital. If either (i) the introduction of or
any change in or in the interpretation of any law or regulation or (ii)
compliance by any Lender with any guideline or request from any central bank or
other governmental authority (whether or not having the force of law) affects or
would affect the amount of capital required or expected to be maintained by such
Lender or any corporation controlling such Lender (including any determination
after the Original Effective Date by any such central bank, governmental
authority or comparable agency that, for purposes of capital adequacy
requirements, the Commitments hereunder do not constitute commitments with an
original maturity of one year or less) and such Lender determines that the
amount of such capital is increased by or based upon

                                       34

<PAGE>   39


the existence of such Lender's commitment to lend hereunder and other
commitments of this type, then, within ten days after demand, and delivery to
the Borrower of the certificate referred to in the last sentence of this Section
2.12 by such Lender (with a copy of such demand to the Administrative Agent),
the Borrower shall pay to the Administrative Agent for the account of such
Lender, from time to time as specified by such Lender, additional amounts
sufficient to compensate such Lender or such corporation in the light of such
circumstances, to the extent that such Lender reasonably determines such
increase in capital to be allocable to the existence of such Lender's commitment
to lend hereunder (except any such increase in capital incurred more than, or
compensation attributable to the period before, 90 days prior to the date of
such demand; for the purposes hereof any increase in capital allocable to, or
compensation attributable to, a period prior to the publication or effective
date of such an introduction, change, guideline or request shall be deemed to be
incurred on the later of such publication or effective date). Each Lender agrees
to use its best reasonable efforts promptly to notify the Borrower of any event
referred to in clause (i) or (ii) above, provided that the failure to give such
notice shall not affect the rights of any Lender under this Section 2.12 (except
as otherwise expressly provided above in this Section 2.12). A certificate in
reasonable detail as to the basis for, and the amount of, such compensation
submitted to the Borrower and the Administrative Agent by such Lender shall, in
the absence of manifest error, be conclusive and binding for all purposes.

         SECTION 2.13. Illegality. Notwithstanding any other provision of this
Agreement, if the introduction of or any change in or in the interpretation of
any law or regulation shall make it unlawful, or any central bank or other
governmental authority shall assert that it is unlawful, for any Lender or its
Applicable Lending Office to perform its obligations hereunder to make
Eurodollar Rate Advances or to continue to fund or maintain such Advances
hereunder, such Lender may, by notice to the Borrower and the Administrative
Agent, suspend the right of the Borrower to elect Eurodollar

                                       35

<PAGE>   40


Rate Advances from such Lender and, if necessary in the reasonable opinion of
such Lender to comply with such law or regulation, Convert all such Eurodollar
Rate Advances of such Lender to Base Rate Advances at the latest time permitted
by the applicable law or regulation, and such suspension and, if applicable,
such Conversion shall continue until such Lender notifies the Borrower and the
Administrative Agent that the circumstances making it unlawful for such Lender
to perform such obligations no longer exist (which such Lender shall promptly do
when such circumstances no longer exist). So long as the obligation of any
Lender to make Eurodollar Rate Advances has been suspended under this Section
2.13, all Notices of A Borrowing specifying A Advances of such Type shall be
deemed, as to such Lender, to be requests for Base Rate Advances. Each Lender
agrees to use its best reasonable efforts (including a reasonable effort to
change its Applicable Lending Office or to transfer its affected A Advances to
an affiliate) to avoid any such illegality, provided that such avoidance would
not, in the reasonable judgment of such Lender, be otherwise disadvantageous to
such Lender.

         SECTION 2.14.  Payments and Computations.

                                       36

<PAGE>   41


           (a The Borrower shall make each payment hereunder (including under
Section 2.03, 2.05, 2.06 or 2.19) and under the Notes, whether the amount so
paid is owing to any or all of the Lenders or to the Administrative Agent, not
later than 1:00 P.M. (New York City time) without setoff, counterclaim, or any
other deduction whatsoever, on the day when due in U.S. dollars to the
Administrative Agent in care of The Chase Manhattan Bank, Agency Services, One
Chase Manhattan Plaza, 8th Floor, New York, NY 10081, Attention: Muniram
Appanna, Reference: Burlington Resources Inc., or at such other location
designated by notice to the Borrower from the Administrative Agent and agreed to
by the Borrower, in same day funds. Each such payment made by the Borrower for
the account of any Lender hereunder, when so made to the Administrative Agent,
shall be deemed duly made for all purposes of this Agreement and the Notes,
except that if at any time any such payment is rescinded or must otherwise be
returned by the Administrative Agent or any Lender upon the bankruptcy,
insolvency or reorganization of the Borrower or otherwise, such payment shall be
deemed not to have been so made. The Administrative Agent will promptly
thereafter cause to be distributed like funds relating to the payment of
principal or interest or fees ratably (other than amounts payable pursuant to
Section 2.07, 2.11, 2.12, 2.13, 2.15, 2.19 or 8.04(b)) to the Lenders for the
account of their respective Applicable Lending Offices, and like funds relating
to the payment of any other amount payable to any Lender to such Lender for the
account of its Applicable Lending Office, in each case to be applied in
accordance with the terms of this Agreement. Upon its acceptance of an
Assignment and Acceptance and recording of the information contained therein in
the Register pursuant to Section 8.07(d), from and after the effective date
specified in such Assignment and Acceptance, the Administrative Agent shall make
all payments hereunder and under the Notes in respect of the interest assigned
thereby to the Lender assignee thereunder, and the parties to such Assignment
and Acceptance shall make all appropriate adjustments in such payments for
periods prior to such effective date directly between themselves.

                                       37

<PAGE>   42


         (b All computations of interest based on the Base Rate and of facility
fees and utilization fees (or amounts in lieu thereof) shall be made by the
Administrative Agent on the basis of a year of 365 or 366 days, as the case may
be, and all computations of interest based on the Eurodollar Rate, or the
Effective Federal Funds Rate shall be made by the Administrative Agent, and all
computations of interest pursuant to Section 2.07 shall be made by each Lender
with respect to its own Eurodollar Rate Advances, on the basis of a year of 360
days, in each case for the actual number of days (including the first day but
excluding the last day) occurring in the period for which such interest or fees
are payable. Each determination by the Administrative Agent (or, in the case of
Section 2.07, 2.11, 2.12, 2.13, 2.15, 2.19 or 8.04(b), by each Lender with
respect to its own Advances) of an interest rate or an increased cost, loss or
expense or increased capital or of illegality or taxes hereunder shall be
conclusive and binding for all purposes if made reasonably and in good faith.

         (c Whenever any payment hereunder or under the Notes shall be stated to
be due on a day other than a Business Day, such payment shall be made on the
next succeeding Business Day, and such extension of time shall in such case be
included in the computation of payment of interest or facility fees, as the case
may be; provided, however, if such extension would cause payment of interest on
or principal of Eurodollar Rate Advances to be made in the next following
calendar month, such payment shall be made on the next preceding Business Day.

         (d Unless the Administrative Agent shall have received notice from the
Borrower prior to the date on which any payment is due to the Lenders hereunder
that the Borrower will not make such payment in full, the Administrative Agent
may assume that the Borrower has made such payment in full to the Administrative
Agent on such date and the Administrative Agent may, in reliance upon such
assumption, cause to be distributed to each Lender on such due date an amount
equal to the amount then due such Lender. If and to the extent the Borrower
shall not have so made such payment in full to

                                       38

<PAGE>   43


the Administrative Agent, each Lender shall repay to the Administrative Agent
forthwith on demand such amount distributed to such Lender together with
interest thereon, for each day from the date such amount is distributed to such
Lender until the date such Lender repays such amount to the Administrative
Agent, at a rate equal to the Effective Federal Funds Rate for such day.

         SECTION 2.15.  Taxes.

           (a Any and all payments by the Borrower hereunder or under the Notes
shall be made in accordance with Section 2.14, free and clear of and without
deduction for any and all present or future taxes, levies, imposts, deductions,
charges or withholdings, and all liabilities with respect thereto, excluding in
the case of each Indemnified Party, (i) all taxes, levies, imposts, deductions,
charges, or withholdings, and all liabilities with respect thereto, imposed on
or determined by reference to its income or profits, and all franchise taxes,
and (ii) all other taxes, levies, imposts, deductions, charges, or withholdings
in effect at the time that such Indemnified Party executed this Agreement or
otherwise became an "Indemnified Party" hereunder, and liabilities with respect
thereto, imposed on it by reason of the jurisdiction in which such Indemnified
Party is organized, domiciled, resident or doing business, or any political
subdivision thereof, or by reason of the jurisdiction of its Applicable Lending
Office or any other office from which it makes or maintains any extension of
credit hereunder or any political subdivision thereof (all such non-excluded
taxes, levies, imposts, deductions, charges, withholdings and liabilities in
respect of payments under this Agreement or under the Notes being herein
referred to as "TAXES"). If the Borrower shall be required by law to deduct any
Taxes from or in respect of any sum payable hereunder or under any Note to any
Indemnified Party, (i) the sum payable shall be increased as may be necessary so
that after making all required deductions (including deductions applicable to
additional sums payable under

                                       39

<PAGE>   44


this Section 2.15) such Indemnified Party receives an amount equal to the sum it
would have received had no such deductions been made, (ii) the Borrower (or the
Administrative Agent, as applicable) shall make such deductions at the
applicable statutory rate and (iii) the Borrower (or the Administrative Agent,
as applicable) shall pay the full amount deducted to the relevant taxation
authority or other authority in accordance with applicable law, provided that
the Borrower shall not be required to pay any additional amount (and shall be
relieved of any liability with respect thereto) pursuant to this subsection (a)
(or pursuant to Section 2.15(c), except to the extent Section 2.15(c) relates to
Other Taxes) to any Indemnified Party that either (x) on the date such
Indemnified Party executed this Agreement or otherwise became an "Indemnified
Party" hereunder, both (A) was not entitled to submit a U.S. Internal Revenue
Service form 1001 (relating to such Indemnified Party, and entitling it to a
complete exemption from withholding on all amounts to be received by such
Indemnified Party, including fees, pursuant to this Agreement or the Advances)
or a U.S. Internal Revenue Service form 4224 (relating to all amounts to be
received by such Indemnified Party, including fees, pursuant to this Agreement
and the Advances) and (B) is not a United States person (as such term is defined
in Section 7701(a)(30) of the Internal Revenue Code), or (y) has failed to
submit any form or certificate that it was required to file or provide pursuant
to subsection (d) of this Section 2.15 and is entitled to file or give, as
applicable, under applicable law, provided, further, that should an Indemnified
Party become subject to Taxes because of its failure to deliver a form required
hereunder, the Borrower shall take such administrative steps as such Indemnified
Party shall reasonably request to assist such Indemnified Party to recover such
Taxes, and provided further, that each Indemnified Party, with respect to
itself, agrees to indemnify and hold harmless the Borrower from any taxes,
penalties, interest and other expenses, costs and losses incurred or payable by
the Borrower as a result of the failure of the Borrower to

                                       40

<PAGE>   45


comply with its obligations under clauses (ii) or (iii) above in reliance on any
form or certificate provided to it by such Indemnified Party pursuant to this
Section 2.15. If any Indemnified Party receives a net credit or refund in
respect of such Taxes or amounts so paid by the Borrower, it shall promptly
notify the Borrower of such net credit or refund and shall promptly pay such net
credit or refund to the Borrower, provided that the Borrower agrees to return
such net credit or refund if the Indemnified Party to which such net credit or
refund is applicable, is required to repay it. 

         (b) In addition, the Borrower agrees to pay any present or future stamp
or documentary taxes or any other excise or property taxes, charges or similar
levies which arise from any payment made hereunder or under the Notes or from
the execution, delivery or registration of, or otherwise with respect to, this
Agreement or the Notes (hereinafter referred to as "OTHER TAXES").

         (c) The Borrower will indemnify each Indemnified Party for the full
amount of Taxes or Other Taxes (including any Taxes or Other Taxes imposed by
any jurisdiction on amounts payable under this Section 2.15) paid by such
Indemnified Party and any liability (including penalties, interest and expenses)
arising therefrom or with respect thereto except as a result of the gross
negligence (which shall in any event include the failure of such Indemnified
Party to provide to the Borrower any form or certificate that it was required to
provide pursuant to subsection (d) below) or willful misconduct of such
Indemnified Party, whether or not such Taxes or Other Taxes were correctly or
legally asserted. This indemnification shall be made within 30 days from the
date such Indemnified Party makes written demand therefor.

          (d) On or prior to the date on which each Indemnified Party that is
not a United States person (as such term is defined in Section 7701(a)(30) of
the Internal Revenue Code) executes this Agreement or otherwise becomes an
"Indemnified Party" hereunder, such Indemnified Party shall provide the Borrower
and

                                       41

<PAGE>   46


the Administrative Agent with U.S. Internal Revenue Service form 1001 or 4224,
as appropriate, or any successor form prescribed by the U.S. Internal Revenue
Service, certifying that such Indemnified Party is fully exempt from United
States withholding taxes with respect to all payments to be made to such
Indemnified Party hereunder, or other documents satisfactory to the Borrower
indicating that all payments to be made to such Indemnified Party hereunder are
fully exempt from such taxes. Thereafter and from time to time, each such
Indemnified Party shall submit to the Borrower and the Administrative Agent such
additional duly completed and signed copies of one or the other of such forms
(or such successor forms as shall be adopted from time to time by the relevant
United States taxing authorities) as may be (i) notified by the Borrower to such
Indemnified Party and (ii) required under then-current United States law or
regulations to avoid United States withholding taxes on payments in respect of
all amounts to be received by such Indemnified Party pursuant to this Agreement
or the Notes, including fees. Upon the request of the Borrower from time to
time, each Indemnified Party that is a United States person (as such term is
defined in Section 7701(a)(30) of the Internal Revenue Code) shall submit to the
Borrower a certificate to the effect that it is such a United States person. If
any Indemnified Party determines, as a result of any change in applicable law,
regulation or treaty, or in any official application or interpretation thereof,
that it is unable to submit to the Borrower any form or certificate that such
Indemnified Party is obligated to submit pursuant to this subsection (d), or
that such Indemnified Party is required to withdraw or cancel any such form or
certificate previously submitted, such Indemnified Party shall promptly notify
the Borrower and the Administrative Agent of such fact.

         (e) Any Indemnified Party claiming any additional amounts payable
pursuant to this Section 2.15 shall use its best reasonable efforts (consistent
with its internal policy and legal and regulatory restrictions) to change the
jurisdiction of its Applicable Lending Office if the making of such a change
would avoid the

                                       42

<PAGE>   47


need for, or reduce the amount of, any such additional amounts which may
thereafter accrue and would not, in the reasonable judgment of such Indemnified
Party, be otherwise disadvantageous to such Indemnified Party.

         (f) Without prejudice to the survival of any other agreement of the
Borrower hereunder, the agreements and obligations of the Borrower and each
Indemnified Party contained in this Section 2.15 shall survive the payment in
full of principal and interest hereunder and under the Notes.

         SECTION 2.16. Sharing of Payments, Etc. If any Lender shall obtain any
payment (whether voluntary, involuntary, through the exercise of any right of
set-off, or otherwise) on account of the A Advances made by it (other than
pursuant to Section 2.07, 2.11, 2.12, 2.13, 2.15 or 8.04(b)) in excess of its
ratable share of payments on account of the A Advances obtained by all the
Lenders, such Lender shall forthwith purchase from the other Lenders such
participations in the A Advances made by them as shall be necessary to cause
such purchasing Lender to share the excess payment ratably with each of them,
provided, however, that if all or any portion of such excess payment is
thereafter recovered from such purchasing Lender, such purchase from each Lender
shall be rescinded and each Lender shall repay to the purchasing Lender the
purchase price to the extent of such Lender's ratable share (according to the
proportion of (i) the amount of the participation purchased from such Lender as
a result of such excess payment to (ii) the total amount of such excess payment)
of such recovery together with an amount equal to such Lender's ratable share
(according to the proportion of (A) the amount of such Lender's required
repayment to (B) the total amount so recovered from the purchasing Lender) of
any interest or other amount paid or payable by the purchasing Lender in respect
of the total amount so recovered. The Borrower agrees that any Lender so
purchasing a participation from another Lender pursuant to this Section may, to
the fullest extent permitted by law, exercise all its rights of payment
(including the right of set-off) with respect to such participation as fully

                                       43

<PAGE>   48


as if such Lender were the direct creditor of the Borrower in the amount of such
participation.

         SECTION 2.17. Evidence of Debt. The indebtedness of the Borrower to
each Lender in respect of principal of and interest on the Advances shall be
evidenced by a Note payable to the order of such Lender and delivered hereunder
by the Borrower. Notwithstanding the provisions of the Notes for notations to be
made on the grid attached thereto, any Lender may maintain in accordance with
its usual practice an account or accounts evidencing the indebtedness of the
Borrower resulting from Advances and payments made from time to time hereunder
and under the Note payable to its order. In any legal action or proceeding in
respect of this Agreement or such Note, the entries made in such account or
accounts shall be conclusive evidence of the existence and amounts of the
obligations of the Borrower therein recorded, absent manifest error.

         SECTION 2.18. Use of Proceeds. Proceeds of the Advances may be used for
general corporate purposes of the Borrower and its Subsidiaries, including for
acquisitions and for payment of commercial paper issued by the Borrower.

         SECTION 2.19. The B Advances. (a) Each Lender severally agrees that the
Borrower may make B Borrowings under this Section 2.19 from time to time on any
Business Day during the period from the Effective Date until the earlier of (I)
the Termination Date or (II) the date falling 30 days prior to the Stated
Termination Date, in the manner set forth below; provided that (x) each B
Borrowing shall be in an aggregate amount of $25,000,000 or an integral multiple
of $5,000,000 in excess thereof and (y) following the making of each B
Borrowing, the aggregate number of outstanding B Borrowings shall not exceed
seven and the aggregate amount of all Advances then outstanding shall not exceed
the aggregate amount of the Commitments of the Lenders (computed without regard
to any B Reduction).

                                       44

<PAGE>   49


                  (i) The Borrower may request a B Borrowing under this Section
         2.19 by delivering to the Administrative Agent, by telecopy, telefax or
         other teletransmission, a notice of a B Borrowing (a "NOTICE OF B
         BORROWING"), in substantially the form of Exhibit C hereto, specifying
         the date and aggregate amount of the proposed B Borrowing, the maturity
         date for repayment of each B Advance to be made as part of such B
         Borrowing (which maturity date may not be earlier than the date
         occurring 30 days after the date of such B Borrowing or later than the
         earlier of (x) 180 days after the date of such B Borrowing or (y) the
         Stated Termination Date), the interest payment date or dates relating
         thereto, and any other terms to be applicable to such B Borrowing, not
         later than 10:00 A.M. (New York City time) (A) at least one Business
         Day prior to the date of the proposed B Borrowing, if the Borrower
         shall specify in the Notice of B Borrowing that the rates of interest
         to be offered by the Lenders shall be fixed rates per annum and (B) at
         least four Business Days prior to the date of the proposed B Borrowing,
         if the Borrower shall instead specify in the Notice of B Borrowing the
         basis to be used by the Lenders in determining the rates of interest to
         be offered by them. The Administrative Agent shall in turn promptly
         notify each Lender of each request for a B Borrowing received by it
         from the Borrower by sending such Lender a copy of the related Notice
         of B Borrowing.

                 (ii) Each Lender may, if in its sole and absolute discretion it
         elects to do so, irrevocably offer to make one or more B Advances to
         the Borrower as part of such proposed B Borrowing at a rate or rates of
         interest specified by such Lender in its sole discretion, by notifying
         the Administrative Agent (which shall give prompt notice thereof to the
         Borrower), before 10:00 A.M. (New York City time) (x) on the date of
         such proposed B Borrowing in the case of a Notice of B Borrowing
         delivered pursuant to clause

                                       45

<PAGE>   50


         (A) of paragraph (i) above, and (y) three Business Days before the date
         of such proposed B Borrowing in the case of a Notice of B Borrowing
         delivered pursuant to clause (B) of paragraph (i) above, of the maximum
         amount of each B Advance which such Lender would be willing to make as
         part of such proposed B Borrowing (which amount may, subject to clause
         (y) of the proviso to the first sentence of this Section 2.19(a),
         exceed such Lender's Commitment), the rate or rates of interest
         therefor and such Lender's Applicable Lending Office with respect to
         such B Advance; provided that if the Administrative Agent or an
         Affiliate thereof in its capacity as a Lender shall, in its sole
         discretion, elect to make any such offer, it shall notify the Borrower
         of such offer before 9:45 A.M. (New York City time) on the date on
         which notice of such election is to be given to the Administrative
         Agent by the other Lenders. If any Lender shall elect not to make such
         an offer, such Lender shall so notify the Administrative Agent, before
         10:00 A.M. (New York City time) on the date on which notice of such
         election is to be given to the Administrative Agent by the other
         Lenders, and such Lender shall not be obligated to, and shall not, make
         any B Advance as part of such B Borrowing; provided that the failure by
         any Lender to give such notice shall not cause such Lender to be
         obligated to make any B Advance as part of such proposed B Borrowing.

                (iii) The Borrower shall, in turn, before 11:00 A.M. (New York
         City time) (x) on the date of such proposed B Borrowing, in the case of
         a Notice of B Borrowing delivered pursuant to clause (A) of paragraph
         (i) above and (y) three Business Days before the date of such proposed
         B Borrowing in the case of a Notice of B Borrowing delivered pursuant
         to clause (B) of paragraph (i) above, either

                           (A) cancel such B Borrowing by giving the
                  Administrative Agent notice to that effect, or

                                       46

<PAGE>   51


                           (B) accept one or more of the offers made by any
                  Lender or Lenders pursuant to paragraph (ii) above, in order
                  of the lowest to highest rates of interest or margins (or, if
                  two or more Lenders bid at the same rates of interest, and the
                  amount of accepted offers is less than the aggregate amount of
                  such offers, the amount to be borrowed from such Lenders as
                  part of such B Borrowing shall be allocated among such Lenders
                  pro rata on the basis of the maximum amount offered by such
                  Lenders at such rates or margin in connection with such B
                  Borrowing), in any aggregate amount up to the aggregate amount
                  initially requested by the Borrower in the relevant Notice of
                  B Borrowing, by giving notice to the Administrative Agent of
                  the amount of each B Advance (which amount shall be equal to
                  or greater than the minimum amount, and equal to or less than
                  the maximum amount, notified to the Borrower by the
                  Administrative Agent on behalf of such Lender for such B
                  Advance pursuant to paragraph (ii) above) to be made by each
                  Lender as part of such B Borrowing, and reject any remaining
                  offers made by Lenders pursuant to paragraph (ii) above by
                  giving the Administrative Agent notice to that effect.

                 (iv) If the Borrower notifies the Administrative Agent that
         such B Borrowing is cancelled pursuant to paragraph (iii)(A) above, the
         Administrative Agent shall give prompt notice thereof to the Lenders
         and such B Borrowing shall not be made.

                  (v) If the Borrower accepts one or more of the offers made by
         any Lender or Lenders pursuant to paragraph (iii)(B) above, the
         Administrative Agent shall in turn promptly notify (A) each Lender that
         has made an offer as described in paragraph (ii) above, of the date and
         aggregate amount of such B Borrowing and whether or not any offer or
         offers made by such Lender pursuant to paragraph (ii) above have been
         accepted by the

                                       47

<PAGE>   52

         Borrower, (B) each Lender that is to make a B Advance as part of such B
         Borrowing, of the amount of each B Advance to be made by such Lender as
         part of such B Borrowing, and (C) each Lender that is to make a B
         Advance as part of such B Borrowing, upon receipt, that the
         Administrative Agent has received forms of documents appearing to
         fulfill the applicable conditions set forth in Article 3. Each Lender
         that is to make a B Advance as part of such B Borrowing shall, before
         12:00 noon (New York City time) on the date of such B Borrowing
         specified in the notice received from the Administrative Agent pursuant
         to clause (A) of the preceding sentence or any later time when such
         Lender shall have received notice from the Administrative Agent
         pursuant to clause (C) of the preceding sentence, make available for
         the account of its Applicable Lending Office to the Administrative
         Agent at its address referred to in Section 8.02 such Lender's portion
         of such B Borrowing, in same day funds. Upon fulfillment of the
         applicable conditions set forth in Article 3 and after receipt by the
         Administrative Agent of such funds, the Administrative Agent will make
         such funds available to the Borrower at the Administrative Agent's
         aforesaid address. Promptly after each B Borrowing the Administrative
         Agent will notify each Lender of the amount of the B Borrowing, the
         consequent B Reduction and the dates upon which such B Reduction
         commenced and will terminate.

         (b) Within the limits and on the conditions set forth in this Section
2.19, the Borrower may from time to time borrow under this Section 2.19, repay
or prepay pursuant to subsection (c) below, and reborrow under this Section
2.19.

         (c) The Borrower shall repay to the Administrative Agent for the
account of each Lender which has made a B Advance, or each other holder of a
Note, on the maturity date of each B Advance (such maturity date being that
specified by the Borrower for repayment in the related Notice of B Borrowing and
provided in the Note evidencing such B Advance), the then unpaid

                                       48

<PAGE>   53


principal amount of such B Advance. The Borrower shall have no right to prepay
any B Advance unless, and then only on the terms, specified by the Borrower for
such B Advance in the related Notice of B Borrowing delivered pursuant to
Section 2.19(a)(i) and set forth in the Note evidencing such B Advance or unless
the holder of such B Advance otherwise consents in writing to such prepayment.

         (d) The Borrower shall pay interest on the unpaid principal amount of
each B Advance from the date of such B Advance to the date the principal amount
of such B Advance is repaid in full at the rate of interest for such B Advance
specified by the Lender making such B Advance in its notice delivered pursuant
to subsection (a)(ii) above on the interest date or dates specified by the
Borrower for such B Advance in the related Notice of B Borrowing and set forth
in the Note evidencing such B Advance, subject to Section 2.06(b).

         (e) Each time that the Borrower gives a Notice of B Borrowing, the
Borrower shall pay to the Administrative Agent for its own account such fee as
may be agreed between the Borrower and the Administrative Agent from time to
time, whether or not any B Borrowing is in fact made.

         (f) Following the making of each B Borrowing, the Borrower agrees that
it will be in compliance with the limitations set forth in clause (y) of the
proviso to the first sentence of Section 2.19(a).

         (g) The failure of any Lender to make the B Advance to be made by it as
part of any B Borrowing shall not relieve any other Lender of its obligation, if
any, hereunder to make its B Advance on the date of such B Borrowing, but no
Lender shall be responsible for the failure of any other Lender to make the B
Advance to be made by such other Lender on the date of any B Borrowing. If any
Designated Bidder fails to make the B Advance to be made by it as part of any B
Borrowing, such Designated Bidder shall not thereafter have the right to offer
to make any B Advance without the prior written consent of the Borrower and the
Administrative Agent.

         SECTION 2.20. Increase of Commitments. (a) At any time after the
Effective Date, provided that no Event

                                       49

<PAGE>   54


of Default shall have occurred and be continuing, the Borrower may request an
increase of the aggregate Commitments by notice to the Administrative Agent in
writing of the amount (the "OFFERED INCREASE AMOUNT") of such proposed increase
(such notice, a "COMMITMENT INCREASE NOTICE"). Any such Commitment Increase
Notice must offer each Lender the opportunity to subscribe for its pro rata
share of the increased Commitments. If any portion of the increased Commitments
is not subscribed for by the Lenders, the Borrower may, in its sole discretion,
but with the consent of the Administrative Agent as to any Person that is not at
such time a Lender (which consent shall not be unreasonably withheld), offer to
any existing Lender or to one or more additional banks or financial institutions
the opportunity to participate in all or a portion of such unsubscribed portion
of the increased Commitments pursuant to paragraph (b) or (c) below, as
applicable.

          (b) Any additional bank or financial institution that the Borrower
selects to offer participation in the increased Commitments, and that elects to
become a party to this Agreement and obtain a Commitment, shall execute a New
Lender Agreement with the Borrower and the Administrative Agent, substantially
in the form of Exhibit E (a "NEW LENDER AGREEMENT"), whereupon such bank or
financial institution (a "NEW LENDER") shall become a Lender for all purposes
and to the same extent as if originally a party hereto and shall be bound by and
entitled to the benefits of this Agreement, and the signature pages hereof shall
be deemed to be amended to add the name and Commitment of such New Lender,
provided that the Commitment of any such New Lender shall be in an amount not
less than $10,000,000.

          (c) Any Lender that accepts an offer to it by the Borrower to increase
its Commitment pursuant to this Section 2.20 shall, in each case, execute a
Commitment Increase Agreement with the Borrower and the Administrative Agent,
substantially in the form of Exhibit F (a "COMMITMENT INCREASE AGREEMENT"),
whereupon such Lender shall be bound by and entitled to the benefits of this
Agreement with respect to the full amount of its Commitment as so increased, and
the

                                       50

<PAGE>   55


signature pages hereof shall be deemed to be amended to so increase the
Commitment of such Lender.

         (d) The effectiveness of any New Lender Agreement or Commitment
Increase Agreement shall be contingent upon receipt by the Administrative Agent
of such corporate resolutions of the Borrower and legal opinions of counsel to
the Borrower as the Administrative Agent shall reasonably request with respect
thereto, in each case, in form and substance satisfactory to the Administrative
Agent.

          (e) If any bank or financial institution becomes a New Lender pursuant
to Section 2.20(b) or any Lender's Commitment is increased pursuant to Section
2.20(c), additional A Advances made on or after the effectiveness thereof (the
"RE-ALLOCATION DATE") shall be made pro rata based on the Commitment Percentages
in effect on and after such Re-Allocation Date (except to the extent that any
such pro rata borrowings would result in any Lender making an aggregate
principal amount of A Advances in excess of its Commitment, in which case such
excess amount will be allocated to, and made by, such New Lender and/or Lenders
with such increased Commitments to the extent of, and pro rata based on, their
respective Commitments), and continuations of Eurodollar Rate Advances
outstanding on such Re-Allocation Date shall be effected by repayment of such
Eurodollar Rate Advances on the last day of the Interest Period applicable
thereto and the making of new Eurodollar Rate Advances pro rata based on such
new Commitment Percentages. In the event that on any such Re-Allocation Date
there is an unpaid principal amount of Base Rate Advances, the Borrower shall
make prepayments thereof and borrowings of Base Rate Advances so that, after
giving effect thereto, the Base Rate Advances outstanding are held pro rata
based on such new Commitment Percentages. In the event that on any such
Re-Allocation Date there is an unpaid principal amount of Eurodollar Rate
Advances, such Eurodollar Rate Advances shall remain outstanding with the
respective holders thereof until the expiration of their respective Interest
Periods (unless the applicable Borrower elects to prepay any thereof in
accordance with the applicable provisions of this

                                       51

<PAGE>   56


Agreement), and interest on and repayments of such Eurodollar Rate Advances will
be paid thereon to the respective Lenders holding such Eurodollar Rate Advances
pro rata based on the respective principal amounts thereof outstanding.

         (f) Notwithstanding anything to the contrary in this Section 2.20, (i)
no increase pursuant to this Section 2.20 shall be effective without the consent
of the Required Lenders, (ii) no Lender shall have any obligation to increase
its Commitment unless it agrees to do so in its sole discretion and (iii) the
aggregate amount by which the Commitments hereunder are increased pursuant to
this Section 2.20 shall not exceed $120,000,000.

         (g) The Borrower shall execute and deliver a Note to each new bank or
other financial institution becoming a Lender.

         SECTION 2.21. Extension of Stated Termination Date. (a) Not earlier
than 65 days prior to and not later than 45 days prior to the Stated Termination
Date then in effect, provided that no Event of Default shall have occurred and
be continuing, the Borrower may request an extension of such Stated Termination
Date by submitting to the Administrative Agent an Extension Request containing
the information in respect of such extension specified in Exhibit G, which the
Administrative Agent shall promptly furnish to each Lender. Each Lender shall,
by the later of (i) the date 30 days after its receipt from the Administrative
Agent of the applicable Extension Request and (ii) the date 30 days prior to the
Stated Termination Date, notify the Borrower and the Administrative Agent of its
election to extend or not extend the Stated Termination Date as requested in
such Extension Request. If the Required Lenders shall approve in writing the
extension of the Stated Termination Date requested in such Extension Request,
and unless the Borrower shall elect to give notice for a Term A Advance pursuant
to Section 2.01(b), the Stated Termination Date shall automatically and without
any further action by any Person be extended for an additional 364 days provided
that the Commitment of any Lender that does not consent in writing within the
period specified above (an

                                       52

<PAGE>   57


"OBJECTING LENDER") shall, unless earlier terminated in accordance with this
Agreement, expire on the Stated Termination Date in effect on the date of such
Extension Request (such Stated Termination Date, if any, referred to as the
"COMMITMENT EXPIRATION DATE" with respect to such Objecting Lender). If, within
the period specified above, the Required Lenders shall not approve in writing
the extension of the Stated Termination Date requested in an Extension Request,
the Stated Termination Date shall not be extended pursuant to such Extension
Request. The Administrative Agent shall promptly notify (y) the Lenders and the
Borrower of any extension of the Stated Termination Date pursuant to this
Section 2.21 and (z) the Borrower of any Lender that becomes an Objecting
Lender.

         (b) A Advances owing to any Objecting Lender on the Commitment
Expiration Date, together with accrued interest thereon, any amounts payable
pursuant to Sections 2.06, 2.07, 2.11, 2.12, 2.15 and 8.04(b) and any accrued
and unpaid facility fee or utilization fee or other amounts payable with respect
to such Lender shall be repaid in full on or before such Commitment Expiration
Date.

         (c) The Borrower shall have the right, so long as no Event of Default
has occurred and is then continuing, upon giving notice to the Administrative
Agent and the Objecting Lenders in accordance with Section 2.10, to prepay in
full the A Advances of the Objecting Lenders, together with accrued interest
thereon, any amounts payable pursuant to Sections 2.06, 2.07, 2.11, 2.12, 2.15
and 8.04(b) and any accrued and unpaid facility fee or utilization fee or other
amounts payable to the Objecting Lenders hereunder and, upon giving not less
than three Business Days' notice to the Objecting Lenders and the Administrative
Agent, to cancel the whole or part of the Commitments of the Objecting Lenders.

         (d) Notwithstanding the foregoing, if any Lender becomes an Objecting
Lender, the Borrower may, at its own expense and in the sole discretion and
prior to the then Stated Termination Date, require such Lender (and each related
Designated Bidder (as defined herein or in the Long-Term Revolving Credit
Agreement)) to transfer

                                       53

<PAGE>   58


or assign, in whole or in part, without recourse (in accordance with Section
8.07), all or part of its interests, rights and obligations under this Agreement
and the Long-Term Revolving Credit Agreement to an Eligible Assignee (provided
that the Borrower, with the full cooperation of such Lender, can identify an
Eligible Assignee that is ready, willing and able to be an assignee with respect
thereto) which shall assume such assigned obligations (which assignee may be
another Lender, if such assignee Lender accepts such assignment); provided that
(A) the assignee or the Borrower, as the case may be, shall have paid to such
Lender in immediately available funds the principal of and interest accrued to
the date of such payment on the Advances made by it hereunder and the "Advances"
made by it under, and as defined in, the Long-Term Revolving Credit Agreement
and all other amounts owed to it hereunder and thereunder, including any amounts
owing pursuant to Section 8.04(b) (or the comparable provision of the Long-Term
Revolving Credit Agreement) and any amounts that would be owing under such
Section (or comparable provision) if such Advances and "Advances" (as so
defined) were prepaid on the date of such assignment, and (B) such assignment
does not conflict with any law, rule or regulation or order of any governmental
authority. Any assignee that becomes a Lender as a result of such an assignment
made pursuant to this paragraph (d) shall be deemed to have consented to the
applicable Extension Request and, therefore, shall not be an Objecting Lender.

         SECTION 2.22. Replacement of Lenders. If any Lender requests
compensation under Sections 2.07, 2.11 or 2.12 or if the Borrower is required to
pay any additional amount to any Lender or any taxing authority or other
authority for the account of any Lender pursuant to Section 2.15, or if any
Lender suspends the right of the Borrower to elect Eurodollar Rate Advances from
such Lender pursuant to Section 2.13, or if any Lender defaults in its
obligation to fund Advances hereunder, then the Borrower may, at its sole
expense and effort, upon notice to such Lender and the Administrative Agent,
require such Lender to assign and delegate, without recourse (in accordance with
and

                                       54

<PAGE>   59


subject to the restrictions contained in Section 8.07), all its interests,
rights and obligations under this Agreement (other than any outstanding B
Advances held by it) and the Long-Term Revolving Credit Agreement (other than "B
Advances" under, and as defined in, the Long-Term Revolving Credit Agreement) to
an assignee that shall assume such obligations (which assignee may be another
Lender, if a Lender accepts such assignment); provided that (i) the Borrower
shall have received the prior written consent of the Administrative Agent, which
consent shall not unreasonably be withheld, (ii) such Lender shall have received
payment of an amount equal to the outstanding principal of its Advances (other
than B Advances) hereunder and its "Advances" (other than "B Advances") (each as
defined in the Long-Term Revolving Credit Agreement), accrued interest thereon,
accrued fees, accrued costs in connection with compensation under Sections 2.07,
2.11 or 2.12 or payments required to be made pursuant to Section 2.15, if any,
and all other amounts payable to it hereunder and thereunder, from the assignee
(to the extent of such outstanding principal and accrued interest and fees) or
the Borrower (in the case of all other amounts) and (iii) in the case of any
such assignment resulting from a claim for compensation under Sections 2.07,
2.11 or 2.12 or payments required to be made pursuant to Section 2.15, such
assignment will result in a reduction in such compensation or payments. A Lender
shall not be required to make any such assignment and delegation if, prior
thereto, as a result of a waiver by such Lender or otherwise, the circumstances
entitling the Borrower to require such assignment and delegation cease to apply.

jurisdiction of its incorporation. The Borrower and each Material Subsidiary
possess all corporate powers and all other authorizations and licenses necessary

          (d) This Agreement constitutes, and the Notes when delivered hereunder
shall constitute, legal, valid and binding obligations of the Borrower
enforceable against the Borrower in accordance with their respective terms,
except as may be limited by applicable bankruptcy, insolvency, reorganization,
moratorium or other similar laws affecting creditors rights generally or by
general principles of equity.

          (e) The consolidated balance sheet of the Borrower and its
consolidated Subsidiaries as at December 31, 1997 and the related consolidated
statements of income and cash flow for the fiscal year then ended, reported on
by PricewaterhouseCoopers LLC, independent public accountants, and the
consolidated balance sheet of the Borrower and its consolidated subsidiaries as
at September 30, 1998 and the related consolidated statements of income and cash
flow for the nine-month period then ended, certified by the chief financial
officer of the Borrower, copies of each of which have been furnished to the
Administrative Agent and the Initial Lenders, fairly present the consolidated
financial condition of the Borrower and such Subsidiaries as at December 31,
1997, and September 30, 1998, respectively, and the consolidated results of
their operations for such fiscal periods, subject in the case of the September
30, 1998, statements to normal year-end adjustments, all in accordance with
generally accepted accounting principles consistently applied. From September
30, 1998 to and including the Effective Date there has been no material adverse
change in such condition or results of operations.

          (f) As at the Effective Date, there is no action, suit or proceeding
pending, or to the knowledge of the

                                       60

Borrower threatened, against or involving the Borrower or any Material
Subsidiary in any court, or before any arbitrator of any kind, or before or by
any governmental body, which in the reasonable judgment of the Borrower (taking
into account the exhaustion of all appeals) would have a material adverse effect
on the consolidated financial condition of the Borrower and its consolidated
Subsidiaries taken as a whole, or which purports to affect the legality,
validity, binding effect or enforceability of this Agreement or the Notes.

          (g) The Borrower and each consolidated Subsidiary have duly filed all
tax returns required to be filed, and duly paid and discharged all taxes,
assessments and governmental charges upon it or against its properties now due
and payable, the failure to file or pay which, as applicable, would have a
Material Adverse Effect, unless and to the extent only that the same are being
contested in good faith and by appropriate proceedings by the Borrower or the
appropriate Subsidiary.

          (h) Except to the extent permitted pursuant to Section 5.02(e),
neither the Borrower nor any Material Subsidiary is subject to any contractual
restrictions which limit the amount of dividends payable by any Subsidiary.

          (i) No Termination Event has occurred or is reasonably expected to
occur with respect to any Plan which, with the giving of notice or lapse of
time, or both, would constitute an Event of Default under Section 6.01(g).

          (j) Neither the Borrower nor any ERISA Affiliate has incurred, or is
reasonably expected to incur, any Withdrawal Liability to any Multiemployer Plan
that, when aggregated with all other amounts required to be paid to
Multiemployer Plans in connection with Withdrawal Liability (as of the date of
determination), exceeds 5% of the Consolidated Tangible Net Worth of the
Borrower.

          (k) Neither the Borrower nor any ERISA Affiliate has received any
notification that any Multiemployer Plan is in reorganization or has been
terminated, within the meaning of Title IV of ERISA, and no

                                       61

<PAGE>   66


Multiemployer Plan is reasonably expected to be in reorganization or to be
terminated within the meaning of Title IV of ERISA the effect of which
reorganization or termination would be the occurrence of an Event of Default
under Section 6.01(i).

          (l) The Borrower is not an "investment company" or a "company"
controlled by an "investment company" within the meaning of the Investment
Company Act of 1940, as amended.

          (m) The Borrower is not a "holding company" or a "subsidiary company"
of a "holding company", or an "affiliate" of a "holding company" or of a
"subsidiary company" of a "holding company", or a "public utility" within the
meaning of the Public Utility Holding Company Act of 1935, as amended.

         (n) Any reprogramming required to permit the proper functioning, in and
following the year 2000, of (i) the computer systems of the Borrower and its
Subsidiaries and (ii) equipment containing embedded microchips (including
systems and equipment supplied by others or with which the Borrower's systems
interface) and the testing of all such systems and equipment, as so
reprogrammed, will be completed by June 30, 1999, except any such reprogramming
or testing of systems or equipment where the failure to so complete would not
reasonably be expected to have a Material Adverse Effect. The cost to the
Borrower and its Subsidiaries of such reprogramming and testing and of the
reasonably foreseeable consequences of year 2000 to the Borrower and its
Subsidiaries (including reprogramming errors and the failure of others' systems
or equipment) will not result in an Event of Default or constitute an Event of
Default but for the requirement that notice be given or time elapse or both and
would not reasonably be expected to have a Material Adverse Effect. Except for
such of the reprogramming referred to in the preceding sentence as may be
necessary, the computer and management information systems of the Borrower and
its Subsidiaries are reasonably expected to be and, with ordinary course
upgrading and maintenance, are reasonably expected to continue for the term of
this Agreement to be, sufficient to permit the Borrower to conduct its
businesses without Material Adverse Effect.

                            COVENANTS OF THE BORROWER

         SECTION 5.1. Affirmative Covenants. So long as any Note or other amount
payable by the Borrower hereunder shall remain unpaid or any Lender shall have
any Commitment hereunder, the Borrower will, unless the Majority Lenders shall
otherwise consent in writing:

          (a) PRESERVATION OF CORPORATE EXISTENCE, ETC. Preserve and maintain,
and cause each Material Subsidiary to preserve and maintain, its corporate
existence, rights (charter and statutory) and material franchises, except as
otherwise permitted by Section 5.02(c) or 5.02(d).

          (b) COMPLIANCE WITH LAWS, ETC. Comply, and cause each Subsidiary to
comply, in all material respects, with all applicable laws, rules, regulations
and orders (including all environmental laws and laws requiring payment of all
taxes, assessments and governmental charges imposed upon it or upon its property
except to the extent contested in good faith by appropriate proceedings) the
failure to comply with which would have a Material Adverse Effect.

          (c) VISITATION RIGHTS. At such reasonable times and intervals as the
Administrative Agent or any of the Lenders (other than Designated Bidders) may
desire, permit the Administrative Agent or any of the Lenders (other than
Designated Bidders) to visit the Borrower and to discuss the affairs, finances,
accounts and mineral reserve performance of the Borrower and any of its
Subsidiaries with officers of the Borrower and independent certified public
accountants of the Borrower and any of its Subsidiaries, provided that if an
Event of Default, or an event which with the giving

                                       63

<PAGE>   68


of notice or the passage of time, or both, would become an Event of Default, has
occurred and is continuing, the Administrative Agent or any Lender may, in
addition to the other provisions of this subsection (c) and at such reasonable
times and intervals as the Administrative Agent or any of the Lenders may
desire, visit and inspect, under guidance of officers of the Borrower, any
properties significant to the consolidated operations of the Borrower and its
Subsidiaries, and to examine the books and records of account (other than with
respect to any mineral reserve information that the Borrower determines to be
confidential) of the Borrower and any of its Subsidiaries and to discuss the
affairs, finances and accounts of any of the Borrower's Subsidiaries with any of
the officers of such Subsidiary.

          (d) BOOKS AND RECORDS. Keep, and cause each of its Subsidiaries to
keep, proper books of record and account, in which full and correct entries
shall be made of all financial transactions and the assets and business of the
Borrower and each Subsidiary in accordance with generally accepted accounting
principles either (i) consistently applied or (ii) applied in a changed manner
that does not, under generally accepted accounting principles or public
reporting requirements applicable to the Borrower, either require disclosure in
the consolidated financial statements of the Borrower and its consolidated
Subsidiaries or require the consent of the accountants which (as required by
Section 5.03(b)) report on such financial statements for the fiscal year in
which such change shall have occurred, or (iii) applied in a changed manner not
covered by clause (ii) above provided such change shall have been disclosed to
the Administrative Agent and shall have been consented to by the accountants
which (as required by Section 5.03(b)) report on the consolidated financial
statements of the Borrower and its consolidated Subsidiaries for the fiscal year
in which such change shall have occurred, provided that if any change referred
to in clause (ii) or (iii) above would not meet the standard set forth in clause
(i) or (ii) of Section 1.03, the Administrative Agent, the Lenders and

                                       64

<PAGE>   69


the Borrower agree to amend the covenants contained in Section 5.01 and 5.02 so
that the relative protection afforded thereby to the Lenders and the relative
flexibility afforded thereby to the Borrower will in substance be retained after
such amendment, provided, however, that until such amendment becomes effective
hereunder, the covenants as set forth herein shall remain in full force and
effect and those accounting principles applicable to the Borrower and its
consolidated Subsidiaries which do meet the standards set forth in clause (i) or
(ii) of Section 1.03 shall be applied to determine whether or not the Borrower
is in compliance with such covenants.

          (e) MAINTENANCE OF PROPERTIES, ETC. Maintain and preserve, and cause
each Material Subsidiary to maintain and preserve, all of its properties which
are used in the conduct of its business in good working order and condition,
ordinary wear and tear excepted, to the extent that any failure to do so would
have a Material Adverse Effect.

          (f) MAINTENANCE OF INSURANCE. Maintain, and cause each Material
Subsidiary to maintain, insurance with responsible and reputable insurance
companies or associations in such amounts and covering such risks as is usually
carried by companies engaged in similar businesses and owning similar properties
in the same general areas in which the Borrower or such Subsidiary operates.

         SECTION 5.2. Negative Covenants. So long as any Note or other amount
payable by the Borrower hereunder shall remain unpaid or any Lender shall have
any Commitment hereunder, the Borrower will not, unless the Majority Lenders
shall otherwise consent in writing:

          (a) LIENS, ETC. (i) Create, assume or suffer to exist, or permit any
Material Subsidiary to create, assume or suffer to exist, any Liens upon or with
respect to any of the Equity Interests in any Material Subsidiary, whether now

Subsidiary to create or assume, any Liens upon or with respect to any other
assets material to the consolidated operations of the Borrower and its
consolidated Subsidiaries taken as a whole securing the

                                       65

<PAGE>   70


payment of Debt and Guaranties in an aggregate amount (determined without
duplication of amount (so that the amount of a Guaranty will be excluded to the
extent the Debt Guaranteed thereby is included in computing such aggregate
amount)) exceeding the greater of (x) $250,000,000 and (y) 10% of Consolidated
Tangible Net Worth as at the date of such creation or assumption; provided,
however, that this subsection (a) shall not apply to:

                           (A) Liens on assets acquired by the Borrower or any
                  of its Subsidiaries after the Original Effective Date to the
                  extent that such Liens existed at the time of such acquisition
                  and were not placed thereon by or with the consent of the
                  Borrower in contemplation of such acquisition;

                           (B) Liens on Equity Interests acquired after the
                  Original Effective Date in a Business Entity which has become
                  or becomes a Subsidiary of the Borrower, or on assets of any
                  such Business Entity, to the extent that such Liens existed at
                  the time of such acquisition and were not placed thereon by or
                  with the consent of the Borrower in contemplation of such
                  acquisition;

                           (C)   Liens on Margin Stock;

                  other obligations of, or assets of, any Project Financing
                  Subsidiary (or any Equity Interests in, Debt or other
                  obligations of any Business Entity which are owned by any
                  Project Financing Subsidiary) securing the payment of a
                  Project Financing and related obligations;

                           (E)   Permitted Liens;

                           (F) Liens arising out of the refinancing, extension,
                  renewal or refunding of any Debt or Guaranty secured by any
                  Lien permitted by any of the foregoing clauses of this
                  Section, provided that the principal amount of such Debt or
                  Guaranty is not

                                       66

<PAGE>   71

                  increased (except by the amount of costs reasonably incurred
                  in connection with the issuance thereof) and such Debt or
                  Guaranty is not secured by any additional assets that would
                  not have been permitted by this Section to secure the Debt or
                  Guaranty refinanced, extended, renewed or refunded; and

                           (G) Liens on products and proceeds (including
                  dividend, interest and like payments on, and insurance and

                  and accessions and improvements to, collateral subject to
                  Liens permitted by this Section 5.02.

          (b) DEBT, ETC. Create, assume or suffer to exist, or permit any of its
consolidated Subsidiaries to create, assume or suffer to exist, any Debt or any
Guaranty unless, immediately after giving effect to such Debt or Guaranty and
the receipt and application of any proceeds thereof or value received in
connection therewith,

                            (1) the sum (without duplication) of (i)
                  consolidated Debt of the Borrower and its consolidated
                  Subsidiaries plus (ii) the aggregate amount (determined on a
                  consolidated basis) of Guaranties by the Borrower and its
                  consolidated Subsidiaries is less than 60% of Capitalization,
                  provided that Debt for borrowed money either maturing within
                  one year and evidenced by instruments commonly known as
                  commercial paper, or evidenced by variable demand notes or
                  other similar short-term financing instruments issued to
                  commercial banks and trust companies (other than Debt incurred
                  pursuant to this Agreement or the Long-Term Revolving Credit
                  Agreement or any replacement therefor), shall not exceed the

                  institutions; and

                            (2) with respect to any such Debt created or assumed
                  by a consolidated Subsidiary that is either a Subsidiary of
                  the Borrower as of the Original Effective Date or a Subsidiary
                  of the Borrower acquired or created after the Original
                  Effective Date and owning a material portion of the
                  consolidated operating assets existing at the Original
                  Effective Date of the Borrower and its Subsidiaries, the
                  aggregate amount of Debt of the consolidated Subsidiaries of
                  the Borrower referred to above in this paragraph (2) owing to
                  Persons other than the Borrower and its consolidated
                  Subsidiaries is less than the greater of (i) $500,000,000
                  (exclusive of public Debt of LL&E existing at the time LL&E
                  became a Subsidiary, the principal amount of which at such
                  time was approximately $400,000,000, and any refinancing of
                  such Debt, in a principal amount not to exceed the principal
                  amount refinanced) and (ii) 30% of Consolidated Tangible Net
                  Worth as at the date of incurrence or creation of such Debt.

          (c) SALE, ETC. OF ASSETS. Sell, lease or otherwise transfer, or permit
any Material Subsidiary to sell, lease or otherwise transfer (in either case,
whether in one transaction or in a series of transactions, and except, in either
case, to the Borrower or an entity which after giving effect to such transfer
will be or become a Material Subsidiary in which the Borrower's direct or
indirect Equity Interests will be at least as great as its direct or indirect
Equity Interests in the transferor immediately prior thereto, and except as
permitted by Section 5.02(d)), assets constituting all or substantially all of
the consolidated assets of the Borrower and its Material Subsidiaries, provided
that, notwithstanding the foregoing, the Borrower or any Material Subsidiary may
sell, lease or otherwise transfer any Permitted Assets constituting all or

                                       68

substantially all of the consolidated assets of the Borrower and its Material
Subsidiaries, so long as (A) such Permitted Assets are sold, leased or otherwise
transferred in exchange for other Permitted Assets and/or (B) the proceeds from
such sale, lease or other transfer, or an amount equal to the proceeds thereof,
are (x) reinvested within one year in Permitted Assets and/or the development of
Permitted Assets and/or (y) used to repay Debt the proceeds of which were or are
being used for investment in, and/or the development of, Permitted Assets;
provided further that, no such sale, lease or other transfer shall be permitted
by the foregoing proviso unless either (1) after giving effect to such sale,
lease or other transfer, no Event of Default, and no event which with lapse of
time or the giving of notice, or both, would constitute an Event of Default,
shall have occurred and be continuing or (2) the Borrower or the relevant
Material Subsidiary, as the case may be, was contractually obligated, prior to
the occurrence of such Event of Default or event, to consummate such sale, lease
or other transfer.

other Subsidiary or may merge or consolidate with (or liquidate into) the
Borrower, provided that (A) if such Material Subsidiary merges or consolidates
with (or liquidates into) the Borrower, the Borrower shall be the continuing or
surviving corporation, (B) if any such Material Subsidiary merges or
consolidates with (or liquidates into) any other Subsidiary of the Borrower, one
of such Subsidiaries is the surviving corporation and, if either such Subsidiary
is not wholly-owned by the Borrower, such merger or consolidation is on an arm's
length basis and (C) as a result of such merger or consolidation, no Event of
Default, and no event which with lapse of time or the giving of notice, or both,
would constitute an Event of Default, shall have occurred and be continuing, and
(ii) the Borrower or any Material Subsidiary may merge or consolidate with any
other

                                       69

<PAGE>   74


corporation (that is, in addition to the Borrower or any Subsidiary of the
Borrower), provided that (A) if the Borrower merges or consolidates with any
such other corporation, the Borrower is the surviving corporation, (B) if any
Material Subsidiary merges or consolidates with any such other corporation, the
surviving corporation is a wholly-owned Material Subsidiary of the Borrower, and
(C) if either the Borrower or any Material Subsidiary merges or consolidates
with any such other corporation, after giving effect to such merger or
consolidation no Event of Default, and no event which with lapse of time or the
giving of notice, or both, would constitute an Event of Default, shall have
occurred and be continuing.

          (e) DIVIDEND RESTRICTIONS. Create, or consent or agree to, or permit
any of its Material Subsidiaries existing on the Original Effective Date or any
of its Subsidiaries thereafter created or acquired and owning a material portion
of the consolidated operating assets existing at the Original Effective Date of
the Borrower and its Subsidiaries, to create, or consent or agree to, any
restrictions, contained in any agreement or instrument relating to or evidencing
Debt, on any such Subsidiary's ability to pay dividends or to make advances to
the Borrower or any Subsidiary of the Borrower; provided, however, that this
subsection (e) shall not apply to any such restrictions (including any
extensions of the term of any thereof (by amendment, or continuation thereof in
any refinancing of the Debt to which such restriction relates, or otherwise))
applicable to the Equity Interests in any Subsidiary of the Borrower the Equity
Interests in which are acquired by the Borrower after the Original Effective
Date and which restrictions are existing at the time such Subsidiary first
becomes a Subsidiary of the Borrower and are not placed thereon by or with the
consent of the Borrower in contemplation of such acquisition by the Borrower.

         SECTION 5.3. Reporting Requirements. So long as any Note shall remain
unpaid or any Lender shall have any Commitment hereunder, the Borrower will
furnish to each Lender in such reasonable quantities as shall from time to time
be requested by such Lender:

accordance with generally accepted accounting principles, (ii) whether or not
such officer has knowledge of the occurrence of any Event of Default which is
continuing hereunder or of any event not theretofore remedied which with notice
or lapse of time or both would constitute such an Event of Default and, if so,
stating in reasonable detail the facts with respect thereto, (iii) all relevant
facts in reasonable detail to evidence, and the computations as to, whether or
not the Borrower is in compliance with the requirements set forth in subsection
(b) of Section 5.02, and (iv) a listing of all Material Subsidiaries and

financial statements have been prepared in accordance with generally accepted
accounting principles and (ii) a letter from such accountants stating that in
making the investigations necessary for such report they obtained no knowledge,
except as specifically stated therein, of any Event of Default which is
continuing hereunder or of any event

                                       71

<PAGE>   76


not theretofore remedied which with notice or lapse of time or both would
constitute such an Event of Default;

years, a certificate of the chief financial officer of the Borrower stating (i)
whether or not such officer has knowledge of the occurrence of any Event of
Default which is continuing hereunder or of any event not theretofore remedied
which with notice or lapse of time or both would constitute such an Event of
Default and, if so, stating in reasonable detail the facts with respect thereto,
(ii) all relevant facts in reasonable detail to evidence, and the computations
as to, whether or not the Borrower is in compliance with the requirements set
forth in subsection (b) of Section 5.02 and (iii) a listing of all Material

                            THE ADMINISTRATIVE AGENT

         SECTION 7.1. Authorization and Action. Each Lender hereby appoints and
authorizes the Administrative Agent to take such action as agent on its behalf
and to exercise such powers under this Agreement as are delegated to the
Administrative Agent by the terms hereof, together with such powers as are
reasonably incidental thereto. As to any matters not expressly provided for by
this Agreement (including enforcement of this Agreement or collection of the
Notes), the Administrative Agent shall not be required to exercise any
discretion or take any action, but shall be required to act or to refrain from
acting (and shall be fully protected in so acting or refraining from acting)
upon the instructions of the Majority Lenders, and such instructions shall be
binding upon all Lenders and all holders of Notes; provided, however, that the
Administrative Agent shall not be required to take any action which exposes the
Administrative Agent to personal liability or which is contrary to this
Agreement or applicable law. The Administrative Agent agrees to give to each
Lender prompt notice of each notice given to it by the Borrower pursuant to the
terms of this Agreement.

         SECTION 7.2. Administrative Agent's Reliance, Etc.. Neither the
Administrative Agent nor any of its directors, officers, agents or employees
shall be liable for any action taken or omitted to be taken by it or them under
or in connection with this Agreement, except for its or their own gross
negligence or willful misconduct. Without limitation of the generality of the
foregoing, the Administrative Agent: (i) may treat the payee of any Note as the
holder thereof until the Administrative Agent receives and accepts an Assignment
and Acceptance entered into by the Lender which is the payee of such Note, as
assignor, and an Eligible Assignee, as assignee, as provided in Section 8.07;
(ii) may consult with legal counsel (including counsel for the Borrower),
independent public accountants and other experts selected by it and shall not be
liable for any action taken or omitted to be taken in good

                                       79

<PAGE>   84


faith by it in accordance with the advice of such counsel, accountants or
experts; (iii) makes no warranty or representation to any Lender and shall not
be responsible to any Lender for any statements, warranties or representations
(whether written or oral) made in or in connection with this Agreement; (iv)

observance of any of the terms, covenants or conditions of this Agreement on the
part of the Borrower or to inspect the property (including the books and
records) of the Borrower; (v) shall not be responsible to any Lender for the due
execution, legality, validity, enforceability, genuineness, sufficiency or value
of this Agreement or any other instrument or document furnished pursuant hereto;
and (vi) shall incur no liability under or in respect of this Agreement by
acting upon any notice, consent, certificate or other instrument or writing
(which may be by telegram, telecopy, cable or telex) believed by it to be
genuine and signed or sent by the proper party or parties.

         SECTION 7.3. Chase and Affiliates. With respect to its Commitments, the
Advances made by it and the Notes issued to it, Chase shall have the same rights
and powers under this Agreement as any other Lender and may exercise the same as
though it were not the Administrative Agent; and the term "Lender" or "Lenders"
shall, unless otherwise expressly indicated, include Chase in its individual
capacity. Chase and its affiliates may accept deposits from, lend money to, act
as trustee under indentures of, and generally engage in any kind of business
with, the Borrower, any of its Subsidiaries and any Person who may do business
with or own securities of the Borrower or any Subsidiary, all as if Chase were
not the Administrative Agent and without any duty to account therefor to the
other Lenders.

         SECTION 7.4. Lender Credit Decision. Each Lender acknowledges that it
has, independently and without reliance upon the Administrative Agent or any
other Lender and based on the financial statements referred to in Section 4.01
and such other documents and

                                       80

<PAGE>   85


information as it has deemed appropriate, made its own credit analysis and
decision to enter into this Agreement. Each Lender also acknowledges that it
will, independently and without reliance upon the Administrative Agent or any
other Lender and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking action under this Agreement.

         SECTION 7.5. Indemnification. THE LENDERS (OTHER THAN THE DESIGNATED
BIDDERS) AGREE TO INDEMNIFY THE ADMINISTRATIVE AGENT (TO THE EXTENT NOT
REIMBURSED BY THE BORROWER), RATABLY ACCORDING TO THE RESPECTIVE PRINCIPAL
AMOUNTS OF THE NOTES THEN HELD BY EACH OF THEM (OR IF NO NOTES ARE AT THE TIME
OUTSTANDING OR IF ANY NOTES ARE HELD BY PERSONS WHICH ARE NOT LENDERS, RATABLY
ACCORDING TO THE RESPECTIVE AMOUNTS OF THEIR COMMITMENTS OR THE RESPECTIVE
AMOUNTS OF THEIR COMMITMENTS IMMEDIATELY PRIOR TO TERMINATION IF THE COMMITMENTS
HAVE BEEN TERMINATED), FROM AND AGAINST ANY AND ALL LIABILITIES, OBLIGATIONS,
LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES AND
DISBURSEMENTS OF ANY KIND OR NATURE WHATSOEVER WHICH MAY BE IMPOSED ON, INCURRED
BY, OR ASSERTED AGAINST THE ADMINISTRATIVE AGENT IN ANY WAY RELATING TO OR
ARISING OUT OF THIS AGREEMENT, ANY OF THE NOTES OR ANY OTHER INSTRUMENT OR
DOCUMENT FURNISHED PURSUANT HERETO OR IN CONNECTION HEREWITH, OR ANY ACTION
TAKEN OR OMITTED BY THE ADMINISTRATIVE AGENT UNDER THIS AGREEMENT, OR ANY OF THE
NOTES OR ANY OTHER INSTRUMENT OR DOCUMENT FURNISHED PURSUANT HERETO OR IN
CONNECTION HEREWITH; PROVIDED THAT NO LENDER SHALL BE LIABLE FOR ANY PORTION OF
SUCH LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS,
SUITS, COSTS, EXPENSES OR DISBURSEMENTS RESULTING FROM THE ADMINISTRATIVE
AGENT'S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. Without limitation of the
foregoing, each Lender (other than the Designated Bidders) agrees to reimburse
the Administrative Agent promptly upon demand for such Lender's ratable share of
any reasonable out-of-pocket expenses (including counsel fees) incurred by the
Administrative Agent in connection with the preparation, execution, delivery,
administration,

                                       81

proceedings, in bankruptcy or insolvency proceedings, or otherwise) of, or legal
advice in respect of rights or responsibilities under, this Agreement, any of
the Notes or any other instrument or document furnished pursuant hereto or in
connection herewith to the extent that the Administrative Agent acts in its
capacity as Administrative Agent and is not reimbursed for such expenses by the
Borrower.

         SECTION 7.6. Successor Administrative Agent. The Administrative Agent
may resign at any time by giving written notice thereof to the Lenders and the
Borrower and may be removed at any time with or without cause by the Majority
Lenders. Upon any such resignation or removal, the Majority Lenders shall have
the right to appoint a successor Administrative Agent. If no successor
Administrative Agent shall have been so appointed by the Majority Lenders, and
shall have accepted such appointment, within 30 days after the retiring
Administrative Agent's giving of notice of resignation or the Majority Lenders'
removal of the retiring Administrative Agent, then such retiring Administrative
Agent may, on behalf of the Lenders, appoint a successor Administrative Agent,
which shall be a commercial bank organized, or authorized to conduct a banking
business, under the laws of the United States of America or of any State thereof
and having a combined capital and surplus of at least $500,000,000. Upon the
acceptance of any appointment as Administrative Agent hereunder by a successor
Administrative Agent, such successor Administrative Agent shall thereupon
succeed to and become vested with all the rights, powers, privileges and duties
of the retiring Administrative Agent, and the retiring Administrative Agent
shall be discharged from its duties and obligations under this Agreement. After
any retiring Administrative Agent's resignation or removal hereunder as
Administrative Agent, the provisions of this Article 7 shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was
Administrative Agent under this Agreement.

shall until such time as it so notifies the Borrower and the Lenders discharge
its duties under Section 2.19 through the Auction Administrative Agent and all
references to the "Administrative Agent" or to Chase relating to such duties or

Administrative Agent and any Affiliate of Chase serving in such capacity. All
payments to be made to or by the Auction Administrative Agent shall be made
through the Administrative Agent.

the account of such Lender any amounts required to compensate such Lender for
any additional losses, costs or expenses which it may reasonably incur as a
result of such payment or Conversion, including any loss (excluding loss of
anticipated profits), cost or expense incurred by reason of the liquidation or
reemployment of deposits or other funds acquired by any Lender to fund or
maintain such Advance.

          (c) THE BORROWER AGREES TO INDEMNIFY AND HOLD HARMLESS THE
ADMINISTRATIVE AGENT, THE ARRANGER AND EACH LENDER FROM AND AGAINST ANY AND ALL
CLAIMS, DAMAGES, LIABILITIES AND EXPENSES (INCLUDING FEES AND DISBURSEMENTS OF
COUNSEL) WHICH MAY BE INCURRED BY OR ASSERTED AGAINST THE ADMINISTRATIVE AGENT,
THE ARRANGER OR SUCH LENDER IN CONNECTION WITH OR ARISING OUT OF ANY
INVESTIGATION, LITIGATION, OR PROCEEDING (WHETHER OR NOT THE ADMINISTRATIVE
AGENT, THE ARRANGER OR SUCH LENDER IS PARTY THERETO) RELATED TO ANY ACQUISITION
OR PROPOSED ACQUISITION BY THE BORROWER, OR BY ANY SUBSIDIARY OF THE BORROWER,
OF ALL OR ANY PORTION OF THE EQUITY INTERESTS IN, OR SUBSTANTIALLY ALL THE

ASSETS OF, ANY PERSON OR ANY USE OR PROPOSED USE OF THE ADVANCES BY THE BORROWER
(EXCLUDING ANY CLAIMS, DAMAGES, LIABILITIES OR EXPENSES INCURRED BY REASON OF
THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THE PARTY TO BE INDEMNIFIED OR ITS
EMPLOYEES OR ADMINISTRATIVE AGENTS, OR BY REASON OF ANY USE OR DISCLOSURE OF
INFORMATION RELATING TO ANY SUCH ACQUISITION OR USE OR PROPOSED USE OF THE
PROCEEDS BY THE PARTY TO BE INDEMNIFIED OR ITS EMPLOYEES OR ADMINISTRATIVE
AGENTS).

         SECTION 8.5. Right of Set-off. Upon the declaration of the Notes as due
and payable pursuant to the provisions of Section 6.01, each Lender is hereby
authorized at any time and from time to time, to the fullest extent permitted by
law, to set off and apply any and all deposits (general or special, time or
demand, provisional or final) at any time held and other indebtedness at any
time owing by such Lender to or for the credit or the account of the Borrower
against any and all of the obligations of the Borrower now or hereafter existing
under this Agreement and any Note held by such Lender, irrespective of whether
or not such Lender shall have made any demand under this Agreement or such Note
and although such obligations may be unmatured. Each Lender agrees promptly to
notify the Borrower after any such set-off and application made by such Lender,
provided that the failure to give such notice shall not affect the validity of
such set-off and application. The rights of each Lender under this Section 8.05
are in addition to other rights and remedies (including other rights of set-off)
which such Lender may have.

         SECTION 8.6. Binding Effect. This Agreement shall become effective in
accordance with the provisions of Section 3.01, and thereafter shall be binding
upon and inure to the benefit of the Borrower, the Administrative Agent, the
Arranger and each Lender and their respective successors and assigns, except
that the Borrower shall not have the right to assign its rights hereunder or any
interest herein without the prior written consent of all of the Lenders.

         SECTION 8.7.  Assignments and Participations.

          (a) Each Lender (other than a Designated Bidder) may assign to one or
more banks or other financial institutions all or a portion of its rights and
obligations under this Agreement (including all or a portion of its Commitment,
the A Advances owing to it and the Note or Notes held by it); provided, however,
that (i) each such assignment shall be of a constant, and not a varying,
percentage of all such Lender's rights and obligations under this Agreement
(other than any right to make B Advances, any B Advances or any Notes) and the
same constant percentage of all such Lender's rights and obligations under the
Long-Term Revolving Credit Agreement, if any, unless the Long-Term Revolving
Credit Agreement has been terminated, shall be contemporaneously assigned by
such assigning Lender to the same assignee pursuant to Section 8.07(a) of the
Long-Term Revolving Credit Agreement, (ii) the sum of (x) the amount of the
Commitment of the assigning Lender being assigned to the assignee pursuant to
each such assignment (determined as of the date of the Assignment and Acceptance
with respect to such assignment) plus (y) the amount of the "Commitment" of the
assigning Lender under the Long-Term Revolving Credit Agreement
contemporaneously assigned by such assigning Lender to such assignee as
contemplated by clause (i) of this sentence must be equal to or greater than
$25,000,000, or if less, the entire amount of such assigning Lender's
"Commitment" (unless the Borrower and the Administrative Agent shall otherwise
consent, which consent may be withheld for any reason) and must be an integral
multiple of $1,000,000, (iii) each such assignment shall be to an Eligible
Assignee, and (iv) the parties to each such assignment shall execute and deliver
to the Administrative Agent, for its acceptance and recording in the Register,
an Assignment and Acceptance, together with any Note or Notes subject to such
assignment and a processing and recordation fee of $3,000, and shall send to the
Borrower an executed counterpart of such Assignment and Acceptance. Upon such
execution, delivery, acceptance and recording, from and after the effective date
specified in each Assignment and Acceptance, (x) the assignee thereunder

                                       88

<PAGE>   93


shall be a party hereto and, to the extent that rights and obligations hereunder
have been assigned to it pursuant to such Assignment and Acceptance, have the
rights and obligations of a Lender hereunder and (y) the Lender assignor
thereunder shall, to the extent that rights and obligations hereunder have been
assigned by it pursuant to such Assignment and Acceptance, relinquish its rights
and be released from its obligations under this Agreement (and, in the case of
an Assignment and Acceptance covering all or the remaining portion of an
assigning Lender's rights and obligations under this Agreement, such Lender
shall cease to be a party hereto, provided, however, such assigning Lender shall
retain any claim with respect to any fee, interest, cost, expense or indemnity
which accrues, or relates to an event that occurs, prior to the date of such
assignment pursuant to Section 2.03, 2.06, 2.07, 2.11, 2.12, 2.15 or 8.04).

          (b) By executing and delivering an Assignment and Acceptance, each
Lender assignor thereunder and the assignee thereunder confirm to and agree with
each other and the other parties hereto as follows: (i) other than as provided
in such Assignment and Acceptance, such assigning Lender makes no representation
or warranty and assumes no responsibility with respect to any statements,
warranties or representations made in or in connection with this Agreement or
the execution, legality, validity, enforceability, genuineness, sufficiency or
value of this Agreement or any other instrument or document furnished pursuant
hereto; (ii) such assigning Lender makes no representation or warranty and
assumes no responsibility with respect to the financial condition of the
Borrower or the performance or observance by the Borrower of any of its
obligations under this Agreement or any other instrument or document furnished
pursuant hereto; (iii) such assignee confirms that it has received a copy of
this Agreement, together with copies of the financial statements referred to in
Section 4.01 and such other documents and information as it has deemed
appropriate to make its own credit analysis and decision to enter into such
Assignment and Acceptance; (iv) such assignee will,

                                       89

<PAGE>   94


independently and without reliance upon the Administrative Agent, such assigning
Lender or any other Lender and based on such documents and information as it
shall deem appropriate at the time, continue to make its own credit decisions in
taking or not taking action under this Agreement; (v) such assignee confirms
that it is (subject to approval in writing by the Borrower and the
Administrative Agent to the extent required) an Eligible Assignee; (vi) such
assignee appoints and authorizes the Administrative Agent to take such action as
agent on its behalf and to exercise such powers under this Agreement as are
delegated to the Administrative Agent by the terms hereof, together with such
powers as are reasonably incidental thereto; and (vii) such assignee agrees that
it will perform in accordance with their terms all of the obligations which by
the terms of this Agreement are required to be performed by it as a Lender.

          (c) The Administrative Agent shall maintain at its address referred to
in Section 8.02 a copy of each Assignment and Acceptance, each Designation
Agreement, each New Lender Agreement and each Commitment Increase Agreement
delivered to and accepted by it and a register for the recordation of the names
and addresses of the Lenders and, with respect to Lenders other than Designated
Bidders, the Commitment of, and principal amount of the A Advances owing to,
each Lender from time to time (the "REGISTER"). The entries in the Register
shall be conclusive and binding for all purposes, absent manifest error, and the
Borrower, the Administrative Agent and the Lenders may treat each Person whose
name is recorded in the Register as a Lender hereunder for all purposes of this
Agreement. The Register shall be available for inspection by the Borrower or any
Lender at any reasonable time and from time to time upon reasonable prior
notice.

          (d) Upon its receipt of an Assignment and Acceptance executed by an
assigning Lender and an assignee representing that it is an Eligible Assignee,
together with any Note or Notes subject to such assignment, the Administrative
Agent shall, if such Assignment and Acceptance has been completed and is in
substantially the form of Exhibit D hereto, (i) accept

                                       90

<PAGE>   95


such Assignment and Acceptance, (ii) record the information contained therein in
the Register and (iii) give prompt notice thereof to the Borrower. Within five
Business Days after its receipt of such notice and its receipt of an executed
counterpart of such Assignment and Acceptance, the Borrower, at its own expense,
shall execute and deliver to the Administrative Agent in exchange for the
surrendered Note or Notes a new Note to the order of such Eligible Assignee and,
if the assigning Lender has retained a Commitment hereunder, a new Note to the
order of the assigning Lender. Such new Note or Notes shall be dated the
effective date of such Assignment and Acceptance and shall otherwise be in
substantially the form of Exhibit A hereto.

          (e) Each Lender (other than a Designated Bidder) may designate one or
more banks or other entities to have a right to make B Advances as a Lender
pursuant to Section 2.19; provided that (i) such Lender shall have obtained the
written consent of the Administrative Agent and the Borrower, such consent not
to be unreasonably withheld, (ii) no such Lender shall be entitled to make more
than two such designations, (iii) each such Lender making one or more of such
designations shall retain the right to make B Advances as a Lender pursuant to
Section 2.19, (iv) each such designation shall be to a Designated Bidder and (v)
the parties to each such designation shall execute and deliver to the
Administrative Agent, for its acceptance and recording in the Register, a
Designation Agreement. Upon such execution, delivery, acceptance and recording,
from and after the effective date specified in each Designation Agreement, the
designee thereunder shall be a party hereto with a right to make B Advances as a
Lender pursuant to Section 2.19 and the obligations related thereto.

          (f) By executing and delivering a Designation Agreement, the Lender
making the designation thereunder and its designee thereunder confirm and agree
with each other and the other parties hereto as follows: (i) such Lender makes
no representation or warranty and assumes no responsibility with respect to any
statements, warranties or representations made in or in connection

                                       91

<PAGE>   96


with this Agreement or the execution, legality, validity, enforceability,
genuineness, sufficiency or value of this Agreement or any other instrument or
document furnished pursuant hereto, (ii) such Lender makes no representation or
warranty and assumes no responsibility with respect to the financial condition
of the Borrower or the performance or observance by the Borrower of any of its
obligations under this Agreement or any other instrument or document furnished
pursuant hereto; (iii) such designee confirms that it has received a copy of
this Agreement, together with copies of the financial statements referred to in
Section 4.01 and such other documents and information as it has deemed
appropriate to make its own credit analysis and decision to enter into the
Designation Agreement; (iv) such designee will, independently and without
reliance upon the Administrative Agent, such designating Lender or any other
Lender and based on such documents and information as it shall deem appropriate
at the time, continue to make its own credit decisions in taking or not taking
action under this Agreement; (v) such designee confirms that it is a Designated
Bidder; (vi) such designee appoints and authorizes the Administrative Agent to
take such action as agent on its behalf and to exercise such powers under this
Agreement as are delegated to the Administrative Agent by the terms hereof,
together with such powers as are reasonably incidental thereto, and (vii) such
designee agrees that it will perform in accordance with their terms all of the
obligations which by the terms of this Agreement are required to be performed by
it as a Lender.

          (g) Upon its receipt of a Designation Agreement executed by a
designating Lender and a designee representing that it is a Designated Bidder,
the Administrative Agent shall, if such Designation Agreement has been completed
and is substantially in the form of Exhibit K hereto, (i) accept such
Designation Agreement, (ii) record the information contained therein in the
Register and (iii) give prompt notice thereof to the Borrower.

          (h) Each Lender may sell participations to one or more banks or other
entities in or to all or a portion

                                       92

<PAGE>   97


of its rights and obligations under this Agreement (including all or a portion
of its Commitment, and the Advances owing to it and the Note or Notes held by
it); provided, however, that (i) such Lender's obligations under this Agreement
(including its Commitment to the Borrower hereunder) shall remain unchanged,
(ii) such Lender shall remain solely responsible to the other parties hereto for
the performance of such obligations, (iii) such Lender shall remain the holder
of any such Note for all purposes of this Agreement, (iv) the Borrower, the
Administrative Agent and the other Lenders shall continue to deal solely and
directly with such Lender in connection with such Lender's rights and
obligations under this Agreement, (v) such Lender shall continue to be able to
agree to any modification or amendment of this Agreement or any waiver hereunder
without the consent, approval or vote of any such participant or group of
participants, other than modifications, amendments and waivers which (A)
postpone any date fixed for any payment of, or reduce any payment of, principal
of or interest on such Lender's Note or any facility fees or utilization fees
payable under this Agreement, or (B) increase the amount of such Lender's
Commitment in a manner which would have the effect of increasing the amount of a
participant's participation, or (C) reduce the interest rate payable under this
Agreement and such Lender's Note, or (D) consent to the assignment or the
transfer by the Borrower of any of its rights and obligations under the
Agreement, and (vi) except as contemplated by the immediately preceding clause
(v), no participant shall be deemed to be or to have any of the rights or
obligations of a "Lender" hereunder.

          (i) Any Lender may, in connection with any assignment, designation or
participation or proposed assignment, designation or participation pursuant to
this Section 8.07, disclose to the assignee, designee or participant or proposed
assignee, designee or participant, any information relating to the Borrower
furnished to such Lender by or on behalf of the Borrower; provided that, prior
to any such disclosure, the assignee, designee or participant or proposed
assignee, designee or participant shall agree in

                                       93

<PAGE>   98


writing for the benefit of the Borrower to preserve the confidentiality of any
confidential information relating to the Borrower received by it from such
Lender in a manner consistent with Section 8.08.

          (j) Anything in this Agreement to the contrary notwithstanding, any
Lender may at any time create a security interest in all or any portion of its
rights under this Agreement (including the Advances owing to it) and the Notes
issued to it hereunder in favor of any Federal Reserve Bank in accordance with
Regulation A of the Board of Governors of the Federal Reserve System (or any
successor regulation) and the applicable operating circular of such Federal
Reserve Bank.

         SECTION 8.8. Confidentiality. Each Lender and the Administrative Agent
(each, a "PARTY") agrees that it will use its best reasonable efforts not to
disclose, without the prior consent of the Borrower (other than to its, or its
Affiliates, employees, auditors, accountants, counsel or other representatives,
whether existing at the Original Effective Date or any subsequent time), any
information with respect to the Borrower which is furnished pursuant to this
Agreement, provided that any party may disclose any such information (i) as has
become generally available to the public, (ii) as may be required or appropriate
in any report, statement or testimony submitted to any municipal, state or
Federal regulatory body having or claiming to have jurisdiction over such party
or to the Board of Governors of the Federal Reserve System or the Federal
Deposit Insurance Corporation or similar organizations (whether in the United
States or elsewhere) or their successors, (iii) as may be required or
appropriate in response to any summons or subpoena or in connection with any
litigation or regulatory proceeding, (iv) in order to comply with any law,
order, regulation or ruling applicable to such party, or (v) to any prospective
assignee, designee or participant in connection with any contemplated assignment
of any rights or obligations hereunder, any designation or any sale of any
participation therein, by such party pursuant to Section 8.07, if such
prospective assignee, designee or participant, as the case may be, executes an
agreement with the Borrower

                                       94

<PAGE>   99


containing provisions substantially similar to those contained in this Section
8.08; provided, however, that the Borrower acknowledges that the Administrative
Agent has disclosed and may continue to disclose such information as the
Administrative Agent in its sole discretion determines is appropriate to the
Lenders from time to time.

         SECTION 8.9.  Consent to Jurisdiction.

          (a) The Borrower hereby irrevocably submits to the jurisdiction of any
New York State or Federal court sitting in New York City and any appellate court
from any thereof in any action or proceeding by the Administrative Agent, the
Arranger, any Lender or the holder of any Note in respect of, but only in
respect of, any claims or causes of action arising out of or relating to this
Agreement or the Notes (such claims and causes of action, collectively, being
"PERMITTED CLAIMS"), and the Borrower hereby irrevocably agrees that all
Permitted Claims may be heard and determined in such New York State court or in
such Federal court. The Borrower hereby irrevocably waives, to the fullest
extent it may effectively do so, the defense of an inconvenient forum to the
maintenance of such action or proceeding in any aforementioned court in respect
of Permitted Claims. Service of the summons and complaint and any other process
which may be served by the Administrative Agent, the Arranger, any Lender or the
holder of any Note on the Borrower in any such action or proceeding in any
aforementioned court in respect of Permitted Claims may be made by delivering
separate copies of such process to the Borrower by courier and by certified mail
(return receipt requested), fees and postage prepaid at the Borrower's address
specified pursuant to Section 8.02, to the attention of each of the Treasurer
and the Executive Vice President, Law. The Borrower agrees that a final judgment
in any such action or proceeding shall be conclusive and may be enforced in
other jurisdictions by suit on the judgment or in any other manner provided by
law.

          (b) Nothing in this Section 8.09 (i) shall affect the right of the
Arranger, the Borrower, any Lender, the holder of any Note or the Administrative
Agent to

                                       95

<PAGE>   100


serve legal process in any other manner permitted by law or affect any right
otherwise existing of the Borrower, any Lender, the Arranger, the holder of any
Note or the Administrative Agent to bring any action or proceeding in the courts
of other jurisdictions or (ii) shall be deemed to be a general consent to
jurisdiction in any particular court or a general waiver of any defense or a
consent to jurisdiction of the courts expressly referred to in subsection (a)
above in any action or proceeding in respect of any claim or cause of action
other than Permitted Claims.

           SECTION 8.10. Governing Law. This Agreement and the Notes shall be
governed by, and construed in accordance with, the laws of the State of New
York.

         SECTION 8.11. Execution in Counterparts. This Agreement may be executed
in any number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed shall be deemed to be an original
and all of which taken together shall constitute one and the same agreement.
Delivery to the Administrative Agent of a counterpart executed by a Lender shall
constitute delivery of such counterpart to all of the Lenders.

         SECTION 8.12. WAIVER OF JURY TRIAL. THE BORROWER, THE ADMINISTRATIVE
AGENT, AND THE LENDERS HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE ANY AND ALL
RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO
THIS AGREEMENT, ANY OF THE NOTES OR ANY OTHER INSTRUMENT OR DOCUMENT FURNISHED
PURSUANT HERETO OR IN CONNECTION HEREWITH OR THE TRANSACTIONS CONTEMPLATED
HEREBY.

The applicable pricing level shall change on the date of any relevant change in
the rating by S&P or Moody's of any public long term senior unsecured debt
securities of the Borrower. In the case of split ratings from S&P and Moody's,
the rating to be used to determine the applicable pricing level is the higher of
the two (e.g., A-/Baa1 results in Level II pricing), provided that in the event
the split is more than one full category, the average (or the higher of two
intermediate ratings) shall be used (e.g., A-/Baa2 results in Level III pricing,
as does A-/Baa3).

         A.       Pursuant to Section 2.20 of the Credit Agreement, the Borrower
                  has the right, subject to the terms and conditions thereof, to
                  effectuate from time to time an increase in the total
                  Commitments under the Credit Agreement by agreeing with a
                  Lender to increase that Lender's Commitment.

         B.       The Borrower has given notice to the Administrative Agent of
                  its intention to increase the total Commitments pursuant to
                  such Section 2.20 by increasing the Commitment of the
                  Increasing Lender from $_______ to $________, and the
                  Administrative Agent is willing to consent thereto.

Accordingly, the parties hereto agree as follows:

to the various matters set forth herein. The Increasing Lender also acknowledges
that it will, independently and without reliance upon the Administrative Agent

appropriate at the time, continue to make its own credit decisions in taking or

Agreement have been increased does not exceed $120,000,000.

          (e) No event has occurred and is continuing which constitutes an Event

          (f) Unless the Long-Term Revolving Credit Agreement has been
terminated, the Borrower has caused, or is simultaneously causing, the
Increasing Lender's "Commitment" (as defined in the Long-Term Revolving Credit
Agreement) to be increased pursuant to Section 2.20 thereof by the same
percentage as the Increasing Lender's Commitment under the Credit Agreement is
being increased pursuant to Section 2.20 of the Credit Agreement.

Directors of the Borrower sufficient to authorize this Agreement, and such

expenses of the Administrative Agent in connection with the preparation,

                                     FORM OF
               OPINION OF SENIOR VICE PRESIDENT, LAW FOR BORROWER



February 23, 1999


To each of the Lenders and the Agents
   Referred to Below
c/o Chase Bank of Texas, N.A.
600 Travis Street, 20th Floor
Houston, TX 77002



Ladies and Gentlemen:

This opinion is furnished to you pursuant to Section 3.01(d) of the Short-Term
Revolving Credit Agreement, dated as of February 25, 1998, as amended and
restated as of February 23, 1999 (the "Credit Agreement"), among Burlington
Resources Inc., a Delaware corporation (the "Borrower"), the financial
institutions party thereto (each a "Lender," and together the "Lenders"), Chase
Bank of Texas, N.A., as Administrative Agent for the Lenders, The Chase
Manhattan Bank, as Auction Administrative Agent, Citibank, N.A., as Syndication
Agent, and Bank of America National Trust and Savings Association and
BankBoston, N.A., as Documentation Agents. Unless the context otherwise
requires, all capitalized terms used herein without definition shall have the
meanings ascribed to them in the Credit Agreement.

I am Senior Vice President, Law of the Borrower, and I, or attorneys over whom I
exercise supervision, have acted as counsel for the Borrower in connection with
the preparation, execution and delivery of the Credit Agreement.
In that connection, I or such attorneys have examined:

         (1)      The Credit Agreement, executed by the parties thereto;



<PAGE>   135


         (2)      The Notes executed by the Borrower; and

         (3)      The other documents furnished by the Borrower pursuant to
                  Section 3.01 of the Credit Agreement.

I, or attorneys over whom I exercise supervision, have also examined the
originals, or copies certified to our satisfaction, of the agreements,
instruments and other documents, and all of the orders, writs, judgments,
awards, injunctions and decrees, which affect or purport to affect the
Borrower's ability to perform the Borrower's obligations under the Credit
Agreement or the Notes (collectively referred to herein as the "Documents"). In
addition, I, or attorneys over whom I exercise supervision, have examined the
originals, or copies certified to our satisfaction, of such other corporate
records of the Borrower, certificates of public officials and of officers of the
Borrower, and agreements, instruments and other documents, as I have deemed
necessary as a basis for the opinions hereinafter expressed. In all such
examinations, I, or attorneys over whom I exercise supervision, have assumed the
legal capacity of all natural persons executing documents, the genuineness of
all signatures on original or certified, conformed or reproduction copies of
documents of all parties (other than, with respect to the Documents, the
Borrower), the authenticity of original and certified documents and the
conformity to original or certified copies of all copies submitted to such
attorneys or me as conformed or reproduction copies. As to various questions of
fact relevant to the opinions expressed herein, I have relied upon, and assume
the accuracy of, representations and warranties contained in the Credit
Agreement and certificates and oral or written statements and other information
of or from public officials, officers and/or representatives of the Borrower and
others.

To the extent it may be relevant to the opinions expressed herein, I have
assumed that the parties to the Documents other than the Borrower have the power
to enter into and perform such documents and that such documents have been duly
authorized, executed and delivered by, and constitute legal, valid and binding
obligations of, such parties.

The opinions expressed below are limited to the federal laws of the United
States and, to the extent relevant hereto, the General Corporation Law of the
State of Delaware, as currently in effect. I assume no obligation to supplement
this opinion if any



<PAGE>   136


applicable laws change after the date hereof or if I become aware of any facts
that might change the opinions expressed herein after the date hereof.

Based upon the foregoing and upon such investigation as I have deemed necessary,
and subject to the limitations, qualifications and assumptions set forth herein,
I am of the following opinion:

     1.  The Borrower (i) is a corporation duly incorporated and existing in
         good standing under the laws of the State of Delaware, and (ii)
         possesses all the corporate powers and all other authorizations and
         licenses necessary to engage in its business and operations as now
         conducted, the failure to obtain or maintain which would have a
         Material Adverse Effect.

     2.  The execution, delivery and performance by the Borrower of the
         Documents are within the Borrower's corporate powers and have been duly
         authorized by all necessary corporate action in respect of or by the
         Borrower (except to the extent that the Borrower seeks to exercise its
         right under Section 2.20 of the Credit Agreement to effect an increase
         of Commitments), and do not contravene (i) the Borrower's Certificate
         of Incorporation or By-Laws, in each case as amended, (ii) any federal
         law, rule or regulation applicable to the Borrower (excluding
         provisions of federal law expressly referred to in and covered by the
         opinion of Jones, Day, Reavis & Pogue delivered to you in connection
         with the transactions contemplated hereby), or (iii) any contractual
         restriction binding on or affecting the Borrower. The Documents have
         been duly executed and delivered on behalf of the Borrower.

     3.  No authorization or approval or other action by, and no notice to or
         filing with, any federal governmental authority or regulatory body
         (including, without limitation, the Federal Energy Regulatory
         Commission) is required for the due execution, delivery and performance
         by the Borrower of the Documents, except those required in the ordinary
         course of business in connection with the performance by the Borrower
         of its obligations under certain covenants and warranties contained in
         the Documents.

     4.  To the best of my knowledge, there is no action, suit or proceeding
         pending or overtly threatened against or involving



<PAGE>   137


         the Borrower or any of its Material Subsidiaries, which, in my
         reasonable judgment (taking into account the exhaustion of all
         appeals), would have a material adverse effect upon the consolidated
         financial condition of the Borrower and its consolidated Subsidiaries
         taken as a whole, or which purports to affect the legality, validity,
         binding effect or enforceability of any Document.

These opinions are given as of the date hereof and are solely for your benefit
in connection with the transactions contemplated by the Credit Agreement. These
opinions may not be relied upon by you for any other purpose or relied upon by
any other person for any purpose without my prior written consent.


                                       Very truly yours,



                                       L. David Hanower

                                                               February 23, 1999

  Re:  Short-Term Revolving Credit Agreement, dated as of February 25, 1998, and
       amended and restated as of February 23, 1999

Ladies and Gentlemen:

         We have acted as special New York counsel for Burlington Resources
Inc., a Delaware corporation (the "Company"), in connection with the Short-Term
Revolving Credit Agreement, dated as of February 25, 1998, and amended and
restated as of February 23, 1999 (as so amended and restated, the "Credit
Agreement"), among the Company, the financial institutions party thereto (each a
"Lender," and together the "Lenders"), Chase Bank of Texas, N.A., as
Administrative Agent for the Lenders, Citibank, N.A., as Syndication Agent for
the Lenders, Bank of America National Trust and Savings Association and
BankBoston, N.A., as Documentation Agents for the Lenders, and The Chase
Manhattan Bank, as Auction Administrative Agent for the Lenders. This opinion is
delivered to you pursuant to Section 3.01(e) of the Credit Agreement.
Capitalized terms used herein and not otherwise defined herein have the meanings
assigned to such terms in the Credit Agreement. The Uniform Commercial Code, as
amended and in effect in the State of New York, is referred to herein as the "NY
UCC." With your permission, all assumptions and statements of reliance herein
have been made without any independent investigation or verification on our part
except to the extent otherwise expressly stated, and we express no opinion with
respect to the subject matter or accuracy of such assumptions or items upon
which we have relied.



<PAGE>   139


         In connection with the opinions expressed herein, we have examined such
documents, records and matters of law as we have deemed necessary or appropriate
for the purposes of this opinion. We have examined, among other documents, the
following:

         (a)  A facsimile of an executed copy of the Credit Agreement;

         (b) A facsimile of an executed copy of each of the Notes; and

         (c) A facsimile of the Officer's Certificate of the Company delivered
             to us in connection with this opinion, a copy of which is attached
             hereto as Annex A.

The documents referred to in items (a) and (b) above are referred to herein
collectively as the "Documents."

         In all such examinations, we have assumed the legal capacity of all
natural persons executing documents, the genuineness of all signatures, the
authenticity of original and certified documents and the conformity to original
or certified copies of all copies submitted to us as conformed or reproduction
copies. As to various questions of fact relevant to the opinions expressed
herein, we have relied upon, and assume the accuracy of, representations and
warranties contained in the Documents and certificates and oral or written
statements and other information of or from representatives of the Company and
others and assume compliance on the part of all parties to the Documents with
their covenants and agreements contained therein. With respect to the opinions
expressed in paragraph (a) below, our opinions are limited (x) to our actual
knowledge of the Company's specially regulated business activities and
properties based solely upon an officer's certificate in respect of such matters
and without any independent investigation or verification on our part and (y) to
our review of only those laws and regulations that, in our experience, are
normally applicable to transactions of the type contemplated by the Documents.

         To the extent it may be relevant to the opinions expressed herein, we
have assumed that the parties to the Documents other



<PAGE>   140


than the Company have the power to enter into and perform such documents and to
consummate the transactions contemplated thereby and that such documents have
been duly authorized, executed and delivered by, and constitute legal, valid and
binding obligations of, such parties.

         Based upon the foregoing, and subject to the limitations,
qualifications and assumptions set forth herein, we are of the opinion that:

         (a) The execution and delivery to the Administrative Agent and the
Lenders by the Company of the Documents and the performance by the Company of
its obligations thereunder (i) do not require under present law any filing or
registration by the Company with, or approval or consent to the Company of, any
governmental agency or authority of the State of New York, except those, if any,
required in the ordinary course of business in connection with the performance
by the Company of its obligations under certain covenants contained in the
Documents and (ii) do not violate any present law, or present regulation of any
governmental agency or authority, of the State of New York applicable to the
Company or its property.

         (b) Each of the Documents constitutes an enforceable obligation of the
Company in accordance with its terms.

         (c) The borrowings by the Borrower under the Credit Agreement and the
applications of the proceeds thereof as provided in the Credit Agreement will
not violate Regulation T, U or X of the Board of Governors of the Federal
Reserve System.

         The opinions set forth above are subject to the following
qualifications:

         (A) We express no opinion as to:

                      (i) the effect of any law of any jurisdiction other than
         the State of New York wherein the Administrative Agent or any Lender
         may be located or wherein enforcement of any document referred to above
         may be sought that limits the rates of interest legally chargeable or
         collectible; and



<PAGE>   141


                      (ii) any filing, registration, approval or consent of the
         Federal Energy Regulatory Commission or any other United States federal
         agency or authority needed in connection with the execution, delivery
         and performance by the Company of the Documents, the consummation of
         the transactions contemplated thereby and compliance with the terms and
         conditions thereof.

         (B) Our opinions above are subject to (i) applicable bankruptcy,
insolvency, reorganization, fraudulent transfer, voidable preference, moratorium
or similar laws, and related judicial doctrines, from time to time in effect
affecting creditors' rights and remedies generally, (ii) general principles of
equity (including, without limitation, standards of materiality, good faith,
fair dealing and reasonableness, equitable defenses and limits on the
availability of equitable remedies), whether such principles are considered in a
proceeding at law or in equity and (iii) the qualification that certain other
provisions of the Documents may be unenforceable in whole or in part under the
laws (including judicial decisions) of the State of New York or the United
States of America, but the inclusion of such provisions does not affect the
validity as against the Company of the Documents as a whole, and the Documents
contain adequate provisions for enforcing payment of the obligations governed
thereby, subject to the other qualifications contained in this letter.

         (C) We express no opinion as to the enforceability of any provision in
the Documents:

                      (i) permitting the Administrative Agent, any Lender or any
         other person or entity to enforce any right or remedy thereunder,
         except in compliance with the NY UCC and other applicable federal,
         state, local and foreign laws; or

                      (ii) relating to indemnification, contribution or
         exculpation in connection with violations of any securities laws or
         statutory duties or public policy, or in connection with willful,
         reckless or unlawful acts or gross negligence of the indemnified or
         exculpated party or the party receiving contribution; or



<PAGE>   142


                      (iii) relating to exculpation of any party in connection
         with its own negligence that a court would determine in the
         circumstances under applicable law to be unfair or insufficiently
         explicit; or

                      (iv) providing that any Lender or other person or entity
         may exercise set-off rights other than in accordance with and pursuant
         to applicable law; or

                      (v)  relating to forum selection to the extent the forum
         is a federal court; or

                      (vi) relating to forum selection to the extent that the
         enforceability of any such provision is to be determined by any court
         other than a court of the State of New York; or

                      (vii) relating to choice of governing law to the extent
         that the enforceability of any such provision is to be determined by
         any court other than a court of the State of New York; or

                      (viii) specifying that provisions thereof may be waived
         only in writing, to the extent that an oral agreement or an implied
         agreement by trade practice or course of conduct has been created that
         modifies any provision of such Documents; or

                      (ix) giving any person or entity the power to accelerate
         obligations without any notice to the obligor.

         (D) Our opinions as to enforceability are subject to the effect of
generally applicable rules of law that:

                      (i)  provide that forum selection clauses in contracts are
         not necessarily binding on the court(s) in the forum selected; and

                      (ii) limit the availability of a remedy under certain
         circumstances when another remedy has been elected; and

                      (iii) may, where less than all of a contract may be
         unenforceable, limit the enforceability of the balance of



<PAGE>   143


         the contract to circumstances in which the unenforceable portion is not
         an essential part of the agreed exchange; and

                      (iv) govern and afford judicial discretion regarding the
         determination of damages and entitlement to attorneys' fees and other
         costs.

         (E) We express no opinion as to the enforceability of any purported
waiver, release, variation, disclaimer, consent or other agreement to similar
effect (all of the foregoing, collectively, a "Waiver") by the Company under any
of the Documents to the extent limited by provisions of applicable law
(including judicial decisions), or to the extent that such a Waiver applies to a
right, claim, duty, defense or ground for discharge otherwise existing or
occurring as a matter of law (including judicial decisions), except to the
extent that such a Waiver is effective under and is not prohibited by or void or
invalid under applicable law (including judicial decisions).

         (F) For purposes of our opinions above, insofar as they relate to the
Company, we have assumed that (i) the Company is a corporation validly existing
in good standing in its jurisdiction of incorporation, has all requisite power
and authority, and has obtained all requisite corporate, shareholder, third
party and governmental authorizations, consents and approvals, and made all
requisite filings and registrations, necessary to execute, deliver and perform
the Documents (except to the extent noted in paragraph (a) above), and that such
execution, delivery and performance will not violate or conflict with any law,
rule, regulation, order, decree, judgment, instrument or agreement binding upon
or applicable to it or its properties (except to the extent noted in paragraph
(a) above, and (ii) the Documents have been duly executed and delivered by the
Company.

         (G) For purposes of the opinions set forth in paragraph (c) above, we
have assumed that (i) neither the Administrative Agent nor any of the Lenders
has or will have the benefit of any agreement or arrangement (excluding the
Documents) pursuant to which any Advances are directly or indirectly secured by
Margin Stock, (ii) neither the Administrative Agent nor any of the Lenders nor
any of their respective affiliates has extended or will extend any other credit
to the Company directly or indirectly secured by Margin Stock and (iii) neither
the



<PAGE>   144


Administrative Agent nor any of the Lenders has relied or will rely upon any
Margin Stock as collateral in extending or maintaining any Advances pursuant to
the Credit Agreement.

         We express no opinion as to the effect of the compliance or
noncompliance of each of the addressees with any state or federal laws or
regulations applicable to each of them by reason of their status as or
affiliation with a federally insured depository institution, except as expressly
set forth in paragraph (c) above.

         The opinions expressed herein are limited to the federal laws of the
United States of America (in the case of the matters covered in paragraph (c)
above) and the laws of the State of New York (in the case of the matters covered
in paragraphs (a) and (b) above), as currently in effect. Our opinions are
limited to those expressly set forth herein, and we express no opinions by
implication.

         The opinions expressed herein are solely for the benefit of the
Administrative Agent and the Lenders and may not be relied on in any manner or
for any purpose by any other person or entity.

                                       Very truly yours,

or a New Lender Agreement, set forth for such Lender in the Register maintained
by the Administrative Agent pursuant to Section 8.07(c), as such amount may be
reduced pursuant to Section 2.04 (such Lender's "COMMITMENT"), provided that the
aggregate amount of the Commitments of the Lenders shall be deemed used from
time to time to the extent of the aggregate amount of the B Advances then
outstanding and such deemed use of the aggregate amount of such Commitments
shall be applied to all the Lenders ratably according to their respective
Commitments (such deemed use of the aggregate amount of the Commitments being a
"B REDUCTION"). Each A Borrowing shall be in an aggregate amount of $10,000,000
in the case of an A Borrowing comprised of Base Rate Advances and $25,000,000 in
the case of an A Borrowing comprised of Eurodollar Rate Advances, or, in either
case an integral multiple of $1,000,000 in excess thereof (or, in the case of an
A Borrowing of Base Rate Advances, the aggregate unused Commitments, if less)
and shall consist of A Advances of the same Type made on the same day by the
Lenders ratably according to their respective Commitments. Within the limits of
each Lender's Commitment, the Borrower may make more than one Borrowing on any
Business Day and may borrow, prepay pursuant to Section 2.10, and reborrow under
this Section 2.01.

         SECTION 2.2.  Making the A Advances.

          (a) Each A Borrowing shall be made on notice by the Borrower to the
Administrative Agent (a "NOTICE OF A BORROWING") received by the Administrative
Agent, (i) in the case of a proposed A Borrowing comprised of Base Rate
Advances, not later than 10:00 A.M. (New York City time) on the Business Day of
such proposed A Borrowing, and (ii) in the case of a proposed A Borrowing
comprised of Eurodollar Rate Advances, not later than 12:00 noon (New York City
time) on the third Business Day prior to the date of such proposed A Borrowing.
Each Notice of A Borrowing shall be by telecopy, telefax or other
teletransmission or by telephone (and if by telephone, confirmed promptly by
telecopier, telefax or other teletransmission), in substantially the form of
Exhibit B hereto, specifying therein the requested (w) date of such A Borrowing,
(x) Type of A Advances comprising such A Borrowing, (y) aggregate amount of such
A Borrowing, and (z) in the case of an A Borrowing comprised of Eurodollar Rate
Advances, the initial Interest Period for each such A Advance. Each Lender
shall, before 1:00 p.m. (New York City time) on the date of such A Borrowing,
make available for the account of its Applicable Lending Office to the
Administrative Agent at its address at Morgan, 60 Wall Street, 22nd Floor, New
York, New York 10260, Reference: Burlington Resources Inc., or at such other
location designated by notice from the Administrative Agent to the Lenders
pursuant to Section 8.02, in same day funds, such Lender's ratable portion of
such A Borrowing. Immediately after the Administrative Agent's receipt of such
funds and upon fulfillment of the 





                                       17
<PAGE>   22



applicable conditions set forth in Article 3, the Administrative Agent will make
such funds available to the Borrower at Morgan, 60 Wall Street, 22nd Floor, New
York, New York 10260, or at any account of the Borrower maintained by the
Administrative Agent (or any successor Administrative Agent) designated by the
Borrower and agreed to by the Administrative Agent (or such successor
Administrative Agent), in same day funds.

           (b Each Notice of A Borrowing shall be irrevocable and binding on the
Borrower. In the case of any A Borrowing which the related Notice of A Borrowing
specified is to be comprised of Eurodollar Rate Advances, if such A Advances are
not made as a result of any failure to fulfill on or before the date specified
for such A Borrowing the applicable conditions set forth in Article 3, the
Borrower shall indemnify each Lender against any loss, cost or expense incurred
by such Lender as a result of such failure, including any loss, cost or expense
incurred by reason of the liquidation or reemployment of deposits or other funds
acquired by such Lender to fund the A Advance to be made by such Lender as part
of such A Borrowing.

           (c Unless the Administrative Agent shall have received notice from a
Lender prior to the date of any A Borrowing that such Lender will not make
available to the Administrative Agent such Lender's ratable portion of such A
Borrowing, the Administrative Agent may assume that such Lender has made such
portion available to the Administrative Agent on the date of such A Borrowing in
accordance with subsection (a) of this Section 2.02 and the Administrative Agent
may, in reliance upon such assumption, make available to the Borrower on such
date a corresponding amount. If and to the extent such Lender shall not have so
made such ratable portion available to the Administrative Agent, such Lender and
the Borrower severally agree to repay to the Administrative Agent forthwith on
demand such corresponding amount together with interest thereon, for each day
from the date such amount is made available to the Borrower until the date such
amount is repaid to the Administrative Agent, at the Effective Federal Funds
Rate for such day. If such Lender shall repay to the Administrative Agent such
corresponding amount, such amount so repaid shall constitute such Lender's A
Advance to the Borrower as part of such A Borrowing for purposes of this
Agreement.

           (d The failure of any Lender to make the A Advance to be made by it
as part of any A Borrowing shall not relieve any other Lender of its obligation,
if any, hereunder to make its A Advance on the date of such A Borrowing, but no
Lender shall be responsible for the failure of any other Lender to make the A
Advance to be made by such other Lender on the date of any A Borrowing.

the effective date specified in the Assignment and Acceptance or Commitment
Increase Agreement pursuant to which it became a Lender in the case of each
other Lender, in each case until the Termination Date, payable quarterly in
arrears on the last day of each March, June, September and December during the
term of such Lender's Commitment and on the Termination Date, at a rate per

           (b AGENCY FEE. The Borrower agrees to pay to the Administrative
Agent, for its own account, such agency fees as may be separately agreed to in
writing by the Borrower and the Administrative Agent, such fees to be in the
amounts and payable on the dates as may be so agreed to.

           (c ARRANGEMENT FEE. The Borrower agrees to pay to the Administrative
Agent, for its own account, an arrangement fee in the amount and payable on the
date separately agreed to in writing by the Administrative Agent and the
Borrower.

         SECTION 2.4. Reduction of the Commitments. The Borrower shall have the
right, upon at least three Business Days' notice to the Administrative Agent, to
terminate in whole or reduce ratably in part the unused portions of the
Commitments of the Lenders (being the amount by which such Commitments exceed
the aggregate outstanding principal amount of all Advances), provided that each
partial reduction shall be in the aggregate amount of $20,000,000 or any whole
multiple of $1,000,000 in excess thereof.

         SECTION 2.5. Repayment of A Advances. The Borrower shall repay to each
Lender on the Termination Date the aggregate principal amount of the A Advances,
together with accrued interest thereon, then owing to such Lender.

         SECTION 2.6.  Interest on A Advances.

           (a ORDINARY INTEREST. The Borrower shall pay interest on the unpaid
principal amount of each A Advance owing to each Lender from the date of such A
Advance until such principal amount is due (whether at stated maturity, by
acceleration or otherwise), at the following rates:

                   (i BASE RATE ADVANCES. During such periods as such A Advance
         is a Base Rate Advance, a rate per annum equal at all times to the Base
         Rate in effect from time to time, payable quarterly in arrears on 






                                       19
<PAGE>   24



         the last day of each March, June, September and December during such
         periods and on the date such Base Rate Advance shall be Converted or
         due (whether at stated maturity, by acceleration or otherwise).

                  (ii Eurodollar Rate Advances. During such periods as such A
         Advance is a Eurodollar Rate Advance, a rate per annum equal at all
         times during each Interest Period for such A Advance to the sum of the
         Eurodollar Rate for such Interest Period plus the Eurodollar Rate
         Margin in effect from time to time, payable on the last day of each
         such Interest Period and, if any such Interest Period has a duration of
         more than three months, on each day which occurs during such Interest
         Period every three months from the first day of such Interest Period
         and, if such A Advance is Converted into a Base Rate Advance on any
         date other than the last day of any Interest Period for such A Advance,
         on the date of such Conversion or, if later, the Business Day on which
         the Borrower shall have received at least one Business Day's prior
         notice from the Administrative Agent or the applicable Lender of the
         amount of unpaid interest accrued on such A Advances to the date of
         such Conversion.

           (b DEFAULT INTEREST. The Borrower shall pay interest on the unpaid
principal amount of each Advance that is not paid when due (whether at stated
maturity, by acceleration or otherwise) from the date on which such amount is
due until such amount is paid in full, payable on demand, at a rate per annum
equal at all times (i) from such due date to the last day of the then existing
Interest Period therefor, in the case of each Eurodollar Rate Advance, to 1% per
annum above the interest rate per annum required to be paid on such A Advance
immediately prior to the date on which such amount became due and (ii) from and
after the last day of the then existing Interest Period therefor, in the case of
each Eurodollar Rate Advance, and at all times in the case of each Base Rate
Advance or B Advance, to 1% per annum above the Base Rate in effect from time to
time.

         SECTION 2.7. Additional Interest on Eurodollar Rate Advances. If any
Lender shall determine in good faith that reserves under regulations of the
Board of Governors of the Federal Reserve System are required to be maintained
by it in respect of, or a portion of its costs of maintaining reserves under
such regulations is properly attributable to, one or more of its Eurodollar Rate
Advances, the Borrower shall pay to such Lender additional interest on the
unpaid principal amount of each such Eurodollar Rate Advance payable on the same
day or days on which interest is payable on such A Advance, at an interest rate
per annum up to but not exceeding at all times during each Interest Period for
such A Advance the excess of (i) the rate obtained by dividing the Eurodollar
Rate for such Interest Period by a percentage equal to 100% minus the Eurodollar
Reserve Percentage, if any, for such Lender for such Interest Period over (ii)
the Eurodollar Rate for such Interest Period. Any Lender wishing to require
payment of such additional 





                                       20
<PAGE>   25



interest (x) shall so notify the Borrower and the Administrative Agent, in which
case such additional interest on the Eurodollar Rate Advances of such Lender
shall be payable to such Lender at the place indicated in such notice with
respect to each Interest Period commencing at least five Business Days after the
giving of such notice and (y) shall furnish to the Borrower at least five
Business Days prior to each date on which interest is payable on the Eurodollar
Rate Advances an officer's certificate setting forth the amount to which such
Lender is then entitled under this Section, which certificate shall be

         SECTION 2.8.  Interest Rate Determination.

timely information furnished by the remaining Reference Banks.

           (b The Administrative Agent shall give prompt notice to the Borrower
and the Lenders of the applicable interest rate determined by the Administrative
Agent for purposes of Section 2.06(a)(i) or (ii), and the applicable rate, if

         Lender prompt notice by telephone (confirmed in writing) that the
         interest rate cannot be determined for such applicable A Advances,

                  (ii each such A Advance that is a Eurodollar Rate Advance will
         automatically, on the last day of the then existing Interest Period
         therefor, Convert into a Base Rate Advance (or if such A Advance is
         then a Base Rate Advance, will continue as a Base Rate Advance), and

                 (iii the obligations of the Lenders to make, or to Convert A
         Advances into, Eurodollar Rate Advances, as the case may be, shall be
         suspended until the Administrative Agent shall notify the Borrower and
         the Lenders that the circumstances causing such suspension no longer
         exist.




                                       21
<PAGE>   26




           (d If, with respect to any Eurodollar Rate Advances, the Majority
Lenders determine and give notice to the Administrative Agent that as a result
of conditions in or generally affecting the relevant market, the rates of
interest determined on the basis of the Eurodollar Rate for any Interest Period
for such A Advances will not adequately reflect the cost to such Majority
Lenders of making, funding or maintaining their respective Eurodollar Rate
Advances for such Interest Period, the Administrative Agent shall forthwith so
notify the Borrower and the Lenders, whereupon,

                   (i each such Eurodollar Rate Advance will automatically, on
         the last day of the then existing Interest Period therefor, Convert
         into a Base Rate Advance, and

                  (ii the obligation of the Lenders to make, or to Convert A
         Advances into, Eurodollar Rate Advances shall be suspended until the
         Administrative Agent shall notify the Borrower and the Lenders that the
         circumstances causing such suspension no longer exist.

           (e If the Borrower shall fail to select the duration of any Interest
Period for any Eurodollar Rate Advances in accordance with the provisions
contained in the definition of "Interest Period" in Section 1.01, the
Administrative Agent will forthwith so notify the Borrower and the Lenders and
such Eurodollar Rate Advances will automatically, on the last day of the then
existing Interest Period therefor, Convert into Base Rate Advances.

           (f On the date on which the aggregate unpaid principal amount of A
Advances comprising any A Borrowing shall be reduced, by payment or prepayment
or otherwise, to less than $10,000,000, such A Advances shall, if they are
Eurodollar Rate Advances, automatically Convert into Base Rate Advances, and on
and after such date the right of the Borrower to Convert such A Advances into
Eurodollar Rate Advances shall terminate; provided, however, that if and so long
as each such A Advance shall be, or be elected to be Converted to, Eurodollar
Rate Advances having the same Interest Period as Eurodollar Rate Advances
comprising another A Borrowing or other A Borrowings, and the aggregate unpaid
principal amount of all such Eurodollar Rate Advances shall, or upon such
Conversion will, equal or exceed $20,000,000, the Borrower shall have the right
to continue all such Eurodollar Rate Advances as, or to Convert all such A
Advances into, Eurodollar Rate Advances having such Interest Period.

         SECTION 2.9. Voluntary Conversion of A Advances. The Borrower may on
any Business Day, upon notice given to the Administrative Agent, not later than
12:00 noon (New York City time) on the third Business Day prior to the date of
the proposed Conversion, and subject to the provisions of Section 2.08, 2.11 





                                       22
<PAGE>   27



and 2.13, Convert all A Advances of one Type comprising the same A Borrowing
into A Advances of the other Type; provided, however, that any Conversion of any
Eurodollar Rate Advances into Base Rate Advances made on any day other than the
last day of an Interest Period for such Eurodollar Rate Advances shall be
subject to the provisions of Section 8.04(b). Each such notice of a Conversion
shall, within the restrictions specified above, specify (i) the date of such
Conversion, (ii) the A Advances to be Converted, and (iii) if such Conversion is
into Eurodollar Rate Advances, the duration of the Interest Period for each such
Eurodollar Rate Advance.

         SECTION 2.10. Prepayments. The Borrower may, upon (i) in the case of
Eurodollar Rate Advances, at least three Business Days notice or (ii) in the
case of Base Rate Advances, telephonic notice not later than 12:00 noon (New

shall, prepay the outstanding principal amounts of the A Advances comprising the
same A Borrowing in whole or ratably in part, together with accrued interest to
the date of such prepayment on the amount prepaid; provided, however, that (x)
each partial prepayment shall be in an aggregate principal amount not less than
$10,000,000 or an integral multiple of $1,000,000 in excess thereof and (y) in
the event of any such prepayment of Eurodollar Rate Advances on any day other
than the last day of an Interest Period for such Eurodollar Rate Advances, the
Borrower shall be obligated to reimburse the Lenders in respect thereof pursuant
to, and to the extent required by, Section 8.04(b); provided, further, however,
that the Borrower will use its best efforts to give notice to the Administrative
Agent of the proposed prepayment of Base Rate Advances on the Business Day prior
to the date of such proposed prepayment.

         SECTION 2.11. Increased Costs.

           (a If, due to either (i) the introduction after the date of this
Agreement of or any change after the date of this Agreement (including any
change by way of imposition or increase of reserve requirements or assessments
other than those referred to in the definition of "Eurodollar Reserve
Percentage" contained in Section 1.01) in or in the interpretation of any law or
regulation or (ii) the compliance with any guideline or request issued or made
after the date of this Agreement from or by any central bank or other
governmental authority (whether or not having the force of law), in each case
above other than those referred to in Section 2.12, there shall be any increase
in the cost to any Lender of agreeing to make, fund or maintain, or of making,
funding or maintaining, Eurodollar Rate Advances funded in the interbank
Eurodollar market, then the Borrower shall from time to time, upon demand by
such Lender (with a copy of such demand to 





                                       23
<PAGE>   28


the Administrative Agent), pay to the Administrative Agent for the account of
such Lender additional amounts sufficient to reimburse such Lender for all such
increased costs (except those incurred more than 60 days prior to the date of
such demand; for the purposes hereof any cost or expense allocable to a period
prior to the publication or effective date of such an introduction, change,
guideline or request shall be deemed to be incurred on the later of such
publication or effective date). Each Lender agrees to use its best reasonable
efforts promptly to notify the Borrower of any event referred to in clause (i)
or (ii) above, provided that the failure to give such notice shall not affect
the rights of any Lender under this Section 2.11(a) (except as otherwise
expressly provided above in this Section 2.11(a)). A certificate as to the
amount of such increased cost, submitted to the Borrower and the Administrative
Agent by such Lender, shall be conclusive and binding for all purposes, absent
manifest error. After one or more Lenders have notified the Borrower of any
increased costs pursuant to this Section 2.11, the Borrower may specify by
notice to the Administrative Agent and the affected Lenders that, after the date
of such notice whenever the election of a Eurodollar Rate Advance by the
Borrower for an Interest Period or portion thereof would give rise to such
increased costs, such election shall not apply to the A Advances of such Lender
or Lenders during such Interest Period or portion thereof, and, in lieu thereof,
such A Advances shall during such Interest Period or portion thereof be Base
Rate Advances. Each Lender agrees to use its best reasonable efforts (including
a reasonable effort to change its Applicable Lending Office or to transfer its
affected A Advances to an Affiliate of such Lender) to avoid, or minimize the
amount of, any demand for payment from the Borrower under this Section 2.11,
provided that such avoidance would not, in the reasonable judgment of such
Lender, be otherwise disadvantageous to such Lender.

           (b In the event that any Lender shall change its Eurodollar Lending
Office and such change results (at the time of such change) in increased costs
to such Lender, the Borrower shall not be liable to such Lender for such
increased costs incurred by such Lender to the extent, but only to the extent,
that such increased costs shall exceed the increased costs which such Lender
would have incurred if the Eurodollar Lending Office of such Lender had not been
so changed, but, subject to subsection (a) of this Section 2.11 and to Section
2.13, nothing herein shall require any Lender to change its Eurodollar Lending
Office for any reason.

         SECTION 2.12. Increased Capital. If either (i) the introduction of or
any change in or in the interpretation of any law or regulation or (ii)
compliance by any Lender with any guideline or request from any central bank or
other governmental authority (whether or not having the force of law) affects or
would affect the amount of capital required or expected to be maintained by such
Lender or any corporation controlling such Lender and such Lender determines
that the 





                                       24
<PAGE>   29



amount of such capital is increased by or based upon the existence of such
Lender's commitment to lend hereunder and other commitments of this type, then,
within ten days after demand, and delivery to the Borrower of the certificate
referred to in the last sentence of this Section 2.12 by such Lender (with a
copy of such demand to the Administrative Agent), the Borrower shall pay to the
Administrative Agent for the account of such Lender, from time to time as
specified by such Lender, additional amounts sufficient to compensate such
Lender or such corporation in the light of such circumstances, to the extent
that such Lender reasonably determines such increase in capital to be allocable
to the existence of such Lender's commitment to lend hereunder (except any such
increase in capital incurred more than, or compensation attributable to the
period before, 90 days prior to the date of such demand; for the purposes hereof
any increase in capital allocable to, or compensation attributable to, a period
prior to the publication or effective date of such an introduction, change,
guideline or request shall be deemed to be incurred on the later of such
publication or effective date). Each Lender agrees to use its best reasonable
efforts promptly to notify the Borrower of any event referred to in clause (i)
or (ii) above, provided that the failure to give such notice shall not affect
the rights of any Lender under this Section 2.12 (except as otherwise expressly
provided above in this Section 2.12). A certificate in reasonable detail as to
the basis for, and the amount of, such compensation submitted to the Borrower
and the Administrative Agent by such Lender shall, in the absence of manifest
error, be conclusive and binding for all purposes.

         SECTION 2.13. Illegality. Notwithstanding any other provision of this
Agreement, if the introduction of or any change in or in the interpretation of
any law or regulation shall make it unlawful, or any central bank or other
governmental authority shall assert that it is unlawful, for any Lender or its
Applicable Lending Office to perform its obligations hereunder to make
Eurodollar Rate Advances or to continue to fund or maintain such Advances
hereunder, such Lender may, by notice to the Borrower and the Administrative
Agent, suspend the right of the Borrower to elect Eurodollar Rate Advances from
such Lender and, if necessary in the reasonable opinion of such Lender to comply
with such law or regulation, Convert all such Eurodollar Rate Advances of such
Lender to Base Rate Advances at the latest time permitted by the applicable law
or regulation, and such suspension and, if applicable, such Conversion shall
continue until such Lender notifies the Borrower and the Administrative Agent
that the circumstances making it unlawful for such Lender to perform such
obligations no longer exist (which such Lender shall promptly do when such
circumstances no longer exist). So long as the obligation of any Lender to make
Eurodollar Rate Advances has been suspended under this Section 2.13, all Notices
of A Borrowing specifying A Advances of such Type shall be deemed, as to such
Lender, to be requests for Base Rate Advances. Each Lender agrees to use its
best 




                                       25
<PAGE>   30



reasonable efforts (including a reasonable effort to change its Applicable
Lending Office or to transfer its affected A Advances to an affiliate) to avoid
any such illegality, provided that such avoidance would not, in the reasonable
judgment of such Lender, be otherwise disadvantageous to such Lender.

         SECTION 2.14. Payments and Computations.

           (a The Borrower shall make each payment hereunder (including under
Section 2.03, 2.05 or 2.06) and under the Notes, whether the amount so paid is
owing to any or all of the Lenders or to the Administrative Agent, not later
than 1:00 P.M. (New York City time) without setoff, counterclaim, or any other
deduction whatsoever, on the day when due in U.S. dollars to the Administrative
Agent at Morgan, 60 Wall Street, 22nd Floor, New York, New York 10260,
Reference: Burlington Resources Inc., or at such other location designated by
notice to the Borrower from the Administrative Agent and agreed to by the
Borrower, in same day funds. Each such payment made by the Borrower for the
account of any Lender hereunder, when so made to the Administrative Agent, shall
be deemed duly made for all purposes of this Agreement and the Notes, except
that if at any time any such payment is rescinded or must otherwise be returned
by the Administrative Agent or any Lender upon the bankruptcy, insolvency or
reorganization of the Borrower or otherwise, such payment shall be deemed not to
have been so made. The Administrative Agent will promptly thereafter cause to be
distributed like funds relating to the payment of principal or interest or fees
ratably (other than amounts payable pursuant to Section 2.07, 2.11, 2.12, 2.13,
2.15, 2.19 or 8.04(b)) to the Lenders for the account of their respective
Applicable Lending Offices, and like funds relating to the payment of any other
amount payable to any Lender to such Lender for the account of its Applicable
Lending Office, in each case to be applied in accordance with the terms of this
Agreement. Upon its acceptance of an Assignment and Acceptance and recording of
the information contained therein in the Register pursuant to Section 8.07(d),
from and after the effective date specified in such Assignment and Acceptance,
the Administrative Agent shall make all payments hereunder and under the Notes
in respect of the interest assigned thereby to the Lender assignee thereunder,
and the parties to such Assignment and Acceptance shall make all appropriate
adjustments in such payments for periods prior to such effective date directly
between themselves.

           (b All computations of interest based on the Base Rate and of
facility fees shall be made by the Administrative Agent on the basis of a year
of 365 or 366 days, as the case may be, and all computations of interest based
on the Eurodollar Rate, or the Effective Federal Funds Rate shall be made by the
Administrative Agent, and all computations of interest pursuant to Section 2.07
shall be made by each Lender with respect to its own Eurodollar Rate Advances,





                                       26
<PAGE>   31



on the basis of a year of 360 days, in each case for the actual number of days
(including the first day but excluding the last day) occurring in the period for
which such interest or fees are payable. Each determination by the
Administrative Agent (or, in the case of Section 2.07, 2.11, 2.12, 2.13, 2.15,
2.19 or 8.04(b), by each Lender with respect to its own Advances) of an interest
rate or an increased cost, loss or expense or increased capital or of illegality
or taxes hereunder shall be conclusive and binding for all purposes if made
reasonably and in good faith.

           (c Whenever any payment hereunder or under the Notes shall be stated
to be due on a day other than a Business Day, such payment shall be made on the
next succeeding Business Day, and such extension of time shall in such case be
included in the computation of payment of interest or facility fees, as the case
may be; provided, however, if such extension would cause payment of interest on
or principal of Eurodollar Rate Advances to be made in the next following
calendar month, such payment shall be made on the next preceding Business Day.

           (d Unless the Administrative Agent shall have received notice from
the Borrower prior to the date on which any payment is due to the Lenders
hereunder that the Borrower will not make such payment in full, the
Administrative Agent may assume that the Borrower has made such payment in full
to the Administrative Agent on such date and the Administrative Agent may, in
reliance upon such assumption, cause to be distributed to each Lender on such
due date an amount equal to the amount then due such Lender. If and to the
extent the Borrower shall not have so made such payment in full to the
Administrative Agent, each Lender shall repay to the Administrative Agent
forthwith on demand such amount distributed to such Lender together with
interest thereon, for each day from the date such amount is distributed to such
Lender until the date such Lender repays such amount to the Administrative
Agent, at a rate equal to the Effective Federal Funds Rate for such day.

         SECTION 2.15. Taxes.

           (a Any and all payments by the Borrower hereunder or under the Notes
shall be made in accordance with Section 2.14, free and clear of and without
deduction for any and all present or future taxes, levies, imposts, deductions,
charges or withholdings, and all liabilities with respect thereto, excluding in
the case of each Indemnified Party, (i) all taxes, levies, imposts, deductions,
charges, or withholdings, and all liabilities with respect thereto, imposed on
or determined by reference to its income or profits, and all franchise taxes,
and (ii) all other taxes, levies, imposts, deductions, charges, or withholdings
in effect at the time that such Indemnified Party executed this Agreement or
otherwise became an "Indemnified Party" hereunder, and liabilities with respect
thereto, imposed on it by reason of the jurisdiction in which such Indemnified
Party is organized, 




                                       27
<PAGE>   32



domiciled, resident or doing business, or any political subdivision thereof, or
by reason of the jurisdiction of its Applicable Lending Office or any other
office from which it makes or maintains any extension of credit hereunder or any
political subdivision thereof (all such non-excluded taxes, levies, imposts,
deductions, charges, withholdings and liabilities in respect of payments under
this Agreement or under the Notes being herein referred to as "TAXES"). If the
Borrower shall be required by law to deduct any Taxes from or in respect of any
sum payable hereunder or under any Note to any Indemnified Party, (i) the sum
payable shall be increased as may be necessary so that after making all required
deductions (including deductions applicable to additional sums payable under
this Section 2.15) such Indemnified Party receives an amount equal to the sum it
would have received had no such deductions been made, (ii) the Borrower (or the
Administrative Agent, as applicable) shall make such deductions at the
applicable statutory rate and (iii) the Borrower (or the Administrative Agent,
as applicable) shall pay the full amount deducted to the relevant taxation
authority or other authority in accordance with applicable law, provided that
the Borrower shall not be required to pay any additional amount (and shall be
relieved of any liability with respect thereto) pursuant to this subsection (a)
(or pursuant to Section 2.15(c), except to the extent Section 2.15(c) relates to
Other Taxes) to any Indemnified Party that either (x) on the date such
Indemnified Party executed this Agreement or otherwise became an "Indemnified
Party" hereunder, both (A) was not entitled to submit a U.S. Internal Revenue
Service form 1001 (relating to such Indemnified Party, and entitling it to a
complete exemption from withholding on all amounts to be received by such
Indemnified Party, including fees, pursuant to this Agreement or the Advances)
or a U.S. Internal Revenue Service form 4224 (relating to all amounts to be
received by such Indemnified Party, including fees, pursuant to this Agreement
and the Advances) and (B) is not a United States person (as such term is defined
in Section 7701(a)(30) of the Internal Revenue Code), or (y) has failed to
submit any form or certificate that it was required to file or provide pursuant
to subsection (d) of this Section 2.15 and is entitled to file or give, as
applicable, under applicable law, provided, further, that should an Indemnified
Party become subject to Taxes because of its failure to deliver a form required
hereunder, the Borrower shall take such administrative steps as such Indemnified
Party shall reasonably request to assist such Indemnified Party to recover such
Taxes, and provided further, that each Indemnified Party, with respect to
itself, agrees to indemnify and hold harmless the Borrower from any taxes,
penalties, interest and other expenses, costs and losses incurred or payable by
the Borrower as a result of the failure of the Borrower to comply with its
obligations under clauses (ii) or (iii) above in reliance on any form or
certificate provided to it by such Indemnified Party pursuant to this Section
2.15. If any Indemnified Party receives a net credit or refund in respect of
such Taxes or amounts so paid by the Borrower, it shall promptly notify the
Borrower of such net credit or refund and shall promptly pay such net credit or
refund to the 




                                       28
<PAGE>   33



Borrower, provided that the Borrower agrees to return such net credit or refund
if the Indemnified Party to which such net credit or refund is applicable, is
required to repay it.

           (b In addition, the Borrower agrees to pay any present or future
stamp or documentary taxes or any other excise or property taxes, charges or
similar levies which arise from any payment made hereunder or under the Notes or
from the execution, delivery or registration of, or otherwise with respect to,
this Agreement or the Notes (hereinafter referred to as "OTHER TAXES").

           (c The Borrower will indemnify each Indemnified Party for the full
amount of Taxes or Other Taxes (including any Taxes or Other Taxes imposed by
any jurisdiction on amounts payable under this Section 2.15) paid by such
Indemnified Party and any liability (including penalties, interest and expenses)
arising therefrom or with respect thereto except as a result of the gross
negligence (which shall in any event include the failure of such Indemnified
Party to provide to the Borrower any form or certificate that it was required to
provide pursuant to subsection (d) below) or willful misconduct of such
Indemnified Party, whether or not such Taxes or Other Taxes were correctly or
legally asserted. This indemnification shall be made within 30 days from the
date such Indemnified Party makes written demand therefor.

           (d On or prior to the date on which each Indemnified Party that is
not a United States person (as such term is defined in Section 7701(a)(30) of
the Internal Revenue Code) executes this Agreement or otherwise becomes an
"Indemnified Party" hereunder, such Indemnified Party shall provide the Borrower
and the Administrative Agent with U.S. Internal Revenue Service form 1001 or
4224, as appropriate, or any successor form prescribed by the U.S. Internal
Revenue Service, certifying that such Indemnified Party is fully exempt from
United States withholding taxes with respect to all payments to be made to such
Indemnified Party hereunder, or other documents satisfactory to the Borrower
indicating that all payments to be made to such Indemnified Party hereunder are
fully exempt from such taxes. Thereafter and from time to time, each such
Indemnified Party shall submit to the Borrower and the Administrative Agent such
additional duly completed and signed copies of one or the other of such forms
(or such successor forms as shall be adopted from time to time by the relevant
United States taxing authorities) as may be (i) notified by the Borrower to such
Indemnified Party and (ii) required under then-current United States law or
regulations to avoid United States withholding taxes on payments in respect of
all amounts to be received by such Indemnified Party pursuant to this Agreement
or the Notes, including fees. Upon the request of the Borrower from time to
time, each Indemnified Party that is a United States person (as such term is
defined in Section 7701(a)(30) of the Internal Revenue Code) shall submit to the
Borrower a 







                                       29
<PAGE>   34


certificate to the effect that it is such a United States person. If any
Indemnified Party determines, as a result of any change in applicable law,
regulation or treaty, or in any official application or interpretation thereof,
that it is unable to submit to the Borrower any form or certificate that such
Indemnified Party is obligated to submit pursuant to this subsection (d), or
that such Indemnified Party is required to withdraw or cancel any such form or
certificate previously submitted, such Indemnified Party shall promptly notify
the Borrower and the Administrative Agent of such fact.

           (e Any Indemnified Party claiming any additional amounts payable
pursuant to this Section 2.15 shall use its best reasonable efforts (consistent
with its internal policy and legal and regulatory restrictions) to change the
jurisdiction of its Applicable Lending Office if the making of such a change
would avoid the need for, or reduce the amount of, any such additional amounts
which may thereafter accrue and would not, in the reasonable judgment of such
Indemnified Party, be otherwise disadvantageous to such Indemnified Party.

           (f Without prejudice to the survival of any other agreement of the
Borrower hereunder, the agreements and obligations of the Borrower and each
Indemnified Party contained in this Section 2.15 shall survive the payment in
full of principal and interest hereunder and under the Notes.

         SECTION 2.16. Sharing of Payments, Etc.. If any Lender shall obtain any
payment (whether voluntary, involuntary, through the exercise of any right of
set-off, or otherwise) on account of the A Advances made by it (other than
pursuant to Section 2.07, 2.11, 2.12, 2.13, 2.15 or 8.04(b)) in excess of its
ratable share of payments on account of the A Advances obtained by all the
Lenders, such Lender shall forthwith purchase from the other Lenders such
participations in the A Advances made by them as shall be necessary to cause
such purchasing Lender to share the excess payment ratably with each of them,
provided, however, that if all or any portion of such excess payment is
thereafter recovered from such purchasing Lender, such purchase from each Lender
shall be rescinded and each Lender shall repay to the purchasing Lender the
purchase price to the extent of such Lender's ratable share (according to the
proportion of (i) the amount of the participation purchased from such Lender as
a result of such excess payment to (ii) the total amount of such excess payment)
of such recovery together with an amount equal to such Lender's ratable share
(according to the proportion of (A) the amount of such Lender's required
repayment to (B) the total amount so recovered from the purchasing Lender) of
any interest or other amount paid or payable by the purchasing Lender in respect
of the total amount so recovered. The Borrower agrees that any Lender so
purchasing a participation from another Lender pursuant to this Section may, to
the fullest extent permitted by law, exercise all its rights of payment
(including the right of set-off) with respect to such participation as fully as
if such Lender were the direct creditor of the Borrower in the amount of such
participation.

<PAGE>   35




         SECTION 2.17. Evidence of Debt. The indebtedness of the Borrower to
each Lender in respect of principal of and interest on the Advances shall be
evidenced by a Note payable to the order of such Lender and delivered hereunder
by the Borrower. Notwithstanding the provisions of the Notes for notations to be
made on the grid attached thereto, any Lender may maintain in accordance with
its usual practice an account or accounts evidencing the indebtedness of the
Borrower resulting from Advances and payments made from time to time hereunder
and under the Note payable to its order. In any legal action or proceeding in
respect of this Agreement or such Note, the entries made in such account or
accounts shall be conclusive evidence of the existence and amounts of the
obligations of the Borrower therein recorded, absent manifest error.

         SECTION 2.18. Use of Proceeds. Proceeds of the Advances may be used for
general corporate purposes of the Borrower and its Subsidiaries, including for
acquisitions and for payment of commercial paper issued by the Borrower.

         SECTION 2.19. The B Advances. (a) Each Lender severally agrees that the
Borrower may make B Borrowings under this Section 2.19 from time to time on any
Business Day during the period from the date hereof until the earlier of (I) the
Termination Date or (II) the date falling 30 days prior to the Stated
Termination Date, in the manner set forth below; provided that (x) each B
Borrowing shall be in an aggregate amount of $25,000,000 or an integral multiple
of $5,000,000 in excess thereof and (y) following the making of each B
Borrowing, the aggregate number of outstanding B Borrowings shall not exceed
seven and the aggregate amount of all Advances then outstanding shall not exceed
the aggregate amount of the Commitments of the Lenders (computed without regard
to any B Reduction).

                  (i) The Borrower may request a B Borrowing under this Section
         2.19 by delivering to the Administrative Agent, by telecopy, telefax or
         other teletransmission, a notice of a B Borrowing (a "NOTICE OF B
         BORROWING"), in substantially the form of Exhibit C hereto, specifying
         the date and aggregate amount of the proposed B Borrowing, the maturity
         date for repayment of each B Advance to be made as part of such B
         Borrowing (which maturity date may not be earlier than the date
         occurring 30 days after the date of such B Borrowing or later than the
         earlier of (x) 180 days after the date of such B Borrowing or (y) the
         Stated Termination Date), the interest payment date or dates relating
         thereto, and any other terms to be applicable to such B Borrowing, not
         later than 10:00 A.M. (New York City time) (A) at least one Business
         Day prior to the date of the proposed B Borrowing, if the Borrower
         shall specify in the 




                                       31
<PAGE>   36





         Notice of B Borrowing that the rates of interest to be offered by the
         Lenders shall be fixed rates per annum and (B) at least four Business
         Days prior to the date of the proposed B Borrowing, if the Borrower
         shall instead specify in the Notice of B Borrowing the basis to be used
         by the Lenders in determining the rates of interest to be offered by
         them. The Administrative Agent shall in turn promptly notify each
         Lender of each request for a B Borrowing received by it from the
         Borrower by sending such Lender a copy of the related Notice of B
         Borrowing.

                 (ii) Each Lender may, if in its sole and absolute discretion it
         elects to do so, irrevocably offer to make one or more B Advances to
         the Borrower as part of such proposed B Borrowing at a rate or rates of
         interest specified by such Lender in its sole discretion, by notifying
         the Administrative Agent (which shall give prompt notice thereof to the
         Borrower), before 10:00 A.M. (New York City time) (x) on the date of
         such proposed B Borrowing in the case of a Notice of B Borrowing
         delivered pursuant to clause (A) of paragraph (i) above, and (y) three
         Business Days before the date of such proposed B Borrowing in the case
         of a Notice of B Borrowing delivered pursuant to clause (B) of
         paragraph (i) above, of the maximum amount of each B Advance which such
         Lender would be willing to make as part of such proposed B Borrowing
         (which amount may, subject to clause (y) of the proviso to the first
         sentence of this Section 2.19(a), exceed such Lender's Commitment), the
         rate or rates of interest therefor and such Lender's Applicable Lending
         Office with respect to such B Advance; provided that if the
         Administrative Agent in its capacity as a Lender shall, in its sole
         discretion, elect to make any such offer, it shall notify the Borrower
         of such offer before 9:45 A.M. (New York City time) on the date on
         which notice of such election is to be given to the Administrative
         Agent by the other Lenders. If any Lender shall elect not to make such
         an offer, such Lender shall so notify the Administrative Agent, before
         10:00 A.M. (New York City time) on the date on which notice of such
         election is to be given to the Administrative Agent by the other
         Lenders, and such Lender shall not be obligated to, and shall not, make
         any B Advance as part of such B Borrowing; provided that the failure by
         any Lender to give such notice shall not cause such Lender to be
         obligated to make any B Advance as part of such proposed B Borrowing.

                (iii) The Borrower shall, in turn, before 11:00 A.M. (New York

         to clause (B) of paragraph (i) above, either

                           (A) cancel such B Borrowing by giving the
                  Administrative Agent notice to that effect, or

                           (B) accept one or more of the offers made by any
                  Lender or Lenders pursuant to paragraph (ii) above, in order
                  of the lowest to highest rates of interest or margins (or, if
                  two or more Lenders bid at the same rates of interest, and the
                  amount of accepted offers is less than the aggregate amount of
                  such offers, the amount to be borrowed from such Lenders as
                  part of such B Borrowing shall be allocated among such Lenders
                  pro rata on the basis of the maximum amount offered by such
                  Lenders at such rates or margin in connection with such B
                  Borrowing), in any aggregate amount up to the aggregate amount
                  initially requested by the Borrower in the relevant Notice of
                  B Borrowing, by giving notice to the Administrative Agent of
                  the amount of each B Advance (which amount shall be equal to
                  or greater than the minimum amount, and equal to or less than
                  the maximum amount, notified to the Borrower by the
                  Administrative Agent on behalf of such Lender for such B
                  Advance pursuant to paragraph (ii) above) to be made by each
                  Lender as part of such B Borrowing, and reject any remaining
                  offers made by Lenders pursuant to paragraph (ii) above by
                  giving the Administrative Agent notice to that effect.

                 (iv) If the Borrower notifies the Administrative Agent that
         such B Borrowing is cancelled pursuant to paragraph (iii)(A) above, the
         Administrative Agent shall give prompt notice thereof to the Lenders
         and such B Borrowing shall not be made.

                  (v) If the Borrower accepts one or more of the offers made by
         any Lender or Lenders pursuant to paragraph (iii)(B) above, the
         Administrative Agent shall in turn promptly notify (A) each Lender that
         has made an offer as described in paragraph (ii) above, of the date and
         aggregate amount of such B Borrowing and whether or not any offer or
         offers made by such Lender pursuant to paragraph (ii) above have been
         accepted by the Borrower, (B) each Lender that is to make a B Advance
         as part of such B Borrowing, of the amount of each B Advance to be made
         by such Lender as part of such B Borrowing, and (C) each Lender that is
         to make a B Advance as part of such B Borrowing, upon receipt, that the
         Administrative Agent has received forms of documents appearing to
         fulfill the applicable conditions set forth in Article 3. Each Lender
         that is to 




                                       33
<PAGE>   38




         make a B Advance as part of such B Borrowing shall, before 12:00 noon
         (New York City time) on the date of such B Borrowing specified in the
         notice received from the Administrative Agent pursuant to clause (A) of
         the preceding sentence or any later time when such Lender shall have
         received notice from the Administrative Agent pursuant to clause (C) of
         the preceding sentence, make available for the account of its
         Applicable Lending Office to the Administrative Agent at its address
         referred to in Section 8.02 such Lender's portion of such B Borrowing,
         in same day funds. Upon fulfillment of the applicable conditions set
         forth in Article 3 and after receipt by the Administrative Agent of
         such funds, the Administrative Agent will make such funds available to
         the Borrower at the Administrative Agent's aforesaid address. Promptly
         after each B Borrowing the Administrative Agent will notify each Lender
         of the amount of the B Borrowing, the consequent B Reduction and the
         dates upon which such B Reduction commenced and will terminate.

         (b) Within the limits and on the conditions set forth in this Section
2.19, the Borrower may from time to time borrow under this Section 2.19, repay
or prepay pursuant to subsection (c) below, and reborrow under this Section
2.19.

         (c) The Borrower shall repay to the Administrative Agent for the
account of each Lender which has made a B Advance, or each other holder of a
Note, on the maturity date of each B Advance (such maturity date being that
specified by the Borrower for repayment in the related Notice of B Borrowing and
provided in the Note evidencing such B Advance), the then unpaid principal
amount of such B Advance. The Borrower shall have no right to prepay any B
Advance unless, and then only on the terms, specified by the Borrower for such B
Advance in the related Notice of B Borrowing delivered pursuant to Section
2.19(a)(i) and set forth in the Note evidencing such B Advance or unless the
holder of such B Advance otherwise consents in writing to such prepayment.

         (d) The Borrower shall pay interest on the unpaid principal amount of
each B Advance from the date of such B Advance to the date the principal amount
of such B Advance is repaid in full at the rate of interest for such B Advance
specified by the Lender making such B Advance in its notice delivered pursuant
to subsection (a)(ii) above on the interest date or dates specified by the
Borrower for such B Advance in the related Notice of B Borrowing and set forth
in the Note evidencing such B Advance, subject to Section 2.06(b)

         (e) Each time that the Borrower gives a Notice of B Borrowing, the
Borrower shall pay to the Administrative Agent for its own account such fee as
may be agreed between the Borrower and the Administrative Agent from time to
time, whether or not any B Borrowing is in fact made.





                                       34
<PAGE>   39

         (f) Following the making of each B Borrowing, the Borrower agrees that
it will be in compliance with the limitations set forth in clause (y) of the
proviso to the first sentence of Section 2.19(a).

         (g) The failure of any Lender to make the B Advance to be made by it as
part of any B Borrowing shall not relieve any other Lender of its obligation, if
any, hereunder to make its B Advance on the date of such B Borrowing, but no
Lender shall be responsible for the failure of any other Lender to make the B
Advance to be made by such other Lender on the date of any B Borrowing. If any
Designated Bidder fails to make the B Advance to be made by it as part of any B
Borrowing, such Designated Bidder shall not thereafter have the right to offer
to make any B Advance without the prior written consent of the Borrower and the
Administrative Agent.

         SECTION 2.20. Increase of Commitments. (a) At any time after the
Effective Date, provided that no Event of Default shall have occurred and be
continuing, the Borrower may request an increase of the aggregate Commitments by
notice to the Administrative Agent in writing of the amount (the "OFFERED
INCREASE AMOUNT") of such proposed increase (such notice, a "COMMITMENT INCREASE
NOTICE"). Any such Commitment Increase Notice must offer each Lender the
opportunity to subscribe for its pro rata share of the increased Commitments. If
any portion of the increased Commitments is not subscribed for by the Lenders,
the Borrower may, in its sole discretion, but with the consent of the
Administrative Agent as to any Person that is not at such time a Lender (which
consent shall not be unreasonably withheld), offer to any existing Lender or to
one or more additional banks or financial institutions the opportunity to
participate in all or a portion of such unsubscribed portion of the increased
Commitments pursuant to paragraph (b) or (c) below, as applicable.

          (b) Any additional bank or financial institution that the Borrower
selects to offer participation in the increased Commitments, and that elects to
become a party to this Agreement and obtain a Commitment, shall execute a New
Lender Agreement with the Borrower and the Administrative Agent, substantially
in the form of Exhibit E (a "NEW LENDER AGREEMENT"), whereupon such bank or
financial institution (a "NEW LENDER") shall become a Lender for all purposes
and to the same extent as if originally a party hereto and shall be bound by and
entitled to the benefits of this Agreement, and the signature pages hereof shall
be deemed to be amended to add the name and Commitment of such New Lender,
provided that the Commitment of any such New Lender shall be in an amount not
less than $10,000,000.



                                       35
<PAGE>   40






          (c) Any Lender that accepts an offer to it by the Borrower to increase
its Commitment pursuant to this Section 2.20 shall, in each case, execute a
Commitment Increase Agreement with the Borrower and the Administrative Agent,
substantially in the form of Exhibit F (a "COMMITMENT INCREASE AGREEMENT"),
whereupon such Lender shall be bound by and entitled to the benefits of this
Agreement with respect to the full amount of its Commitment as so increased, and
the signature pages hereof shall be deemed to be amended to so increase the
Commitment of such Lender.

          (d) The effectiveness of any New Lender Agreement or Commitment
Increase Agreement shall be contingent upon receipt by the Administrative Agent
of such corporate resolutions of the Borrower and legal opinions of counsel to
the Borrower as the Administrative Agent shall reasonably request with respect
thereto, in each case, in form and substance satisfactory to the Administrative
Agent.

          (e) If any bank or financial institution becomes a New Lender pursuant
to Section 2.20(b) or any Lender's Commitment is increased pursuant to Section
2.20(c), additional A Advances made on or after the effectiveness thereof (the
"RE-ALLOCATION DATE") shall be made pro rata based on the Commitment Percentages
in effect on and after such Re-Allocation Date (except to the extent that any
such pro rata borrowings would result in any Lender making an aggregate
principal amount of A Advances in excess of its Commitment, in which case such
excess amount will be allocated to, and made by, such New Lender and/or Lenders
with such increased Commitments to the extent of, and pro rata based on, their
respective Commitments), and continuations of Eurodollar Rate Advances
outstanding on such Re-Allocation Date shall be effected by repayment of such
Eurodollar Rate Advances on the last day of the Interest Period applicable
thereto and the making of new Eurodollar Rate Advances pro rata based on such
new Commitment Percentages. In the event that on any such Re-Allocation Date
there is an unpaid principal amount of Base Rate Advances, the Borrower shall
make prepayments thereof and borrowings of Base Rate Advances so that, after
giving effect thereto, the Base Rate Advances outstanding are held pro rata
based on such new Commitment Percentages. In the event that on any such
Re-Allocation Date there is an unpaid principal amount of Eurodollar Rate
Advances, such Eurodollar Rate Advances shall remain outstanding with the
respective holders thereof until the expiration of their respective Interest
Periods (unless the applicable Borrower elects to prepay any thereof in
accordance with the applicable provisions of this Agreement), and interest on
and repayments of such Eurodollar Rate Advances will be paid thereon to the
respective Lenders holding such Eurodollar Rate Advances pro rata based on the
respective principal amounts thereof outstanding.

<PAGE>   41




          (f) Notwithstanding anything to the contrary in this Section 2.20, (i)
no increase pursuant to this Section 2.20 shall be effective without the consent
of the Required Lenders, (ii) no Lender shall have any obligation to increase
its Commitment unless it agrees to do so in its sole discretion and (iii) the
aggregate amount by which the Commitments hereunder are increased pursuant to
this Section 2.20 shall not exceed $180,000,000.

          (g) The Borrower shall execute and deliver a Note to each new bank or
other financial institution becoming a Lender.

         SECTION 2.21. Extension of Stated Termination Date. (a) Not later than
45 days prior to the Stated Termination Date then in effect, provided that no
Event of Default shall have occurred and be continuing, the Borrower may request
an extension of such Stated Termination Date by submitting to the Administrative
Agent an Extension Request containing the information in respect of such
extension specified in Exhibit G, which the Administrative Agent shall promptly
furnish to each Lender. Each Lender shall, no later than 30 days after receiving
from the Administrative Agent the applicable Extension Request, notify the
Borrower and the Administrative Agent of its election to extend or not extend
the Stated Termination Date as requested in such Extension Request. If the
Required Lenders shall approve in writing the extension of the Stated
Termination Date requested in such Extension Request, the Stated Termination
Date shall automatically and without any further action by any Person be
extended for the period specified in such Extension Request; provided that (i)
each extension pursuant to this Section 2.21 shall be for a maximum of one year,
(ii) the Commitment of any Lender that does not consent in writing within 30
days after receiving from the Administrative Agent the applicable Extension
Request (an "OBJECTING LENDER") shall, unless earlier terminated in accordance
with this Agreement, expire on the Stated Termination Date in effect on the date
of such Extension Request (such Stated Termination Date, if any, referred to as
the "COMMITMENT EXPIRATION DATE" with respect to such Objecting Lender) and
(iii) the Borrower may exercise no more than two extensions pursuant to this
Section 2.21, so that the Stated Termination Date shall not in any event extend
beyond the second anniversary of the initial Stated Termination Date hereunder.
If, within 30 days after receiving from the Administrative Agent the applicable
Extension Request, the Required Lenders shall not approve in writing the
extension of the Stated Termination Date requested in an Extension Request, the
Stated Termination Date shall not be extended pursuant to such Extension
Request. The Administrative Agent shall promptly notify (y) the Lenders and the
Borrower of any extension of the Stated Termination Date pursuant to this
Section 2.21 and (z) the Borrower of any Lender that becomes an Objecting
Lender.

          (b) A Advances owing to any Objecting Lender on the Commitment
Expiration Date, together with accrued interest thereon, any amounts payable
pursuant to Sections 2.06, 2.07, 2.11, 2.12, 2.15 and 8.04(b) and any accrued
and unpaid facility fee or other amounts payable with respect to such Lender
shall be repaid in full on or before such Commitment Expiration Date.

          (c) The Borrower shall have the right, so long as no Event of Default
has occurred and is then continuing, upon giving notice to the Administrative
Agent and the Objecting Lenders in accordance with Section 2.10, to prepay in
full the A Advances of the Objecting Lenders, together with accrued interest
thereon, any amounts payable pursuant to Sections 2.06, 2.07, 2.11, 2.12, 2.15
and 8.04(b) and any accrued and unpaid facility fee or other amounts payable to
the Objecting Lenders hereunder and, upon giving not less than three Business
Days' notice to the Objecting Lenders and the Administrative Agent, to cancel
the whole or part of the Commitments of the Objecting Lenders.

          (d) Notwithstanding the foregoing, if any Lender becomes an Objecting
Lender, the Borrower may, at its own expense and in the sole discretion and
prior to the then Stated Termination Date, require such Lender (and each related
Designated Bidder (as defined herein or in the Short-Term Revolving Credit
Agreement)) to transfer or assign, in whole or in part, without recourse (in
accordance with Section 8.07), all or part of its interests, rights and
obligations under this Agreement and the Short-Term Revolving Credit Agreement
to an Eligible Assignee (provided that the Borrower, with the full cooperation
of such Lender, can identify an Eligible Assignee that is ready, willing and
able to be an assignee with respect thereto) which shall assume such assigned
obligations (which assignee may be another Lender, if such assignee Lender
accepts such assignment); provided that (A) the assignee or the Borrower, as the
case may be, shall have paid to such Lender in immediately available funds the
principal of and interest accrued to the date of such payment on the Advances
made by it hereunder and the "Advances" made by it under, and as defined in, the
Short-Term Revolving Credit Agreement and all other amounts owed to it hereunder
and thereunder, including any amounts owing pursuant to Section 8.04(b) (or the
comparable provision of the Short-Term Revolving Credit Agreement) and any
amounts that would be owing under such Section (or comparable provision) if such
Advances and "Advances" (as so defined) were prepaid on the date of such
assignment, and (B) such assignment does not conflict with any law, rule or
regulation or order of any governmental authority. Any assignee that becomes a
Lender as a result of such an assignment made pursuant to this paragraph (d)
shall be deemed to have consented to the applicable Extension Request and,
therefore, shall not be an Objecting Lender.

<PAGE>   43




         SECTION 2.22. Replacement of Lenders. If any Lender requests
compensation under Sections 2.07, 2.11 or 2.12 or if the Borrower is required to
pay any additional amount to any Lender or any taxing authority or other
authority for the account of any Lender pursuant to Section 2.15, or if any
Lender suspends the right of the Borrower to elect Eurodollar Rate Advances from
such Lender pursuant to Section 2.13, or if any Lender defaults in its
obligation to fund Advances hereunder, then the Borrower may, at its sole
expense and effort, upon notice to such Lender and the Administrative Agent,
require such Lender to assign and delegate, without recourse (in accordance with
and subject to the restrictions contained in Section 8.07), all its interests,
rights and obligations under this Agreement (other than any outstanding B
Advances held by it) and the Short-Term Revolving Credit Agreement (other than
"B Advances" under, and as defined in, the Short-Term Revolving Credit
Agreement) to an assignee that shall assume such obligations (which assignee may
be another Lender, if a Lender accepts such assignment); provided that (i) the
Borrower shall have received the prior written consent of the Administrative
Agent, which consent shall not unreasonably be withheld, (ii) such Lender shall
have received payment of an amount equal to the outstanding principal of its
Advances (other than B Advances) hereunder and its "Advances" (other than "B
Advances") (each as defined in the Short-Term Revolving Credit Agreement),
accrued interest thereon, accrued fees, accrued costs in connection with
compensation under Sections 2.07, 2.11 or 2.12 or payments required to be made
pursuant to Section 2.15, if any, and all other amounts payable to it hereunder
and thereunder, from the assignee (to the extent of such outstanding principal
and accrued interest and fees) or the Borrower (in the case of all other
amounts) and (iii) in the case of any such assignment resulting from a claim for
compensation under Sections 2.07, 2.11 or 2.12 or payments required to be made
pursuant to Section 2.15, such assignment will result in a reduction in such
compensation or payments. A Lender shall not be required to make any such
assignment and delegation if, prior thereto, as a result of a waiver by such
Lender or otherwise, the circumstances entitling the Borrower to require such
assignment and delegation cease to apply.

ordinary course to comply with ongoing covenant obligations of the Borrower
hereunder the performance of which is not yet due and (ii) that will, in the
ordinary course of business in accordance with this Agreement, be duly made or
obtained on or prior to the time or times the performance of such obligations
shall be due.

          (d) This Agreement constitutes, and the Notes when delivered hereunder
shall constitute, legal, valid and binding obligations of the Borrower
enforceable against the Borrower in accordance with their respective terms,
except as may be limited by applicable bankruptcy, insolvency, reorganization,
moratorium or other similar laws affecting creditors rights generally or by
general principles of equity.

          (e) The consolidated balance sheet of the Borrower and its
consolidated Subsidiaries as at December 31, 1997 and the related consolidated
statements of income and cash flow for the fiscal year then ended, reported on
by Coopers & Lybrand, independent public accountants, copies of which have been
furnished to the Administrative Agent and the Initial Lenders prior to the date
hereof, fairly present the consolidated financial condition of the Borrower and
such Subsidiaries as at December 31, 1997 and the consolidated results of their
operations for such fiscal period, all in accordance with generally accepted
accounting principles consistently applied. From December 31, 1997 to and
including the Effective Date there has been no material adverse change in such
condition or results of operations.

          (f) As at the Effective Date, there is no action, suit or proceeding
pending, or to the knowledge of the Borrower threatened, against or involving
the Borrower or any Material Subsidiary in any court, or before any arbitrator
of any kind, or before or by any governmental body, which in the reasonable
judgment of the Borrower (taking into account the exhaustion of all appeals)
would have a material adverse effect on the consolidated financial condition of
the Borrower and its consolidated Subsidiaries taken as a whole, or which
purports to affect the legality, validity, binding effect or enforceability of
this Agreement or the Notes.

          (g) The Borrower and each consolidated Subsidiary have duly filed all
tax returns required to be filed, and duly paid and discharged all taxes,
assessments and governmental charges upon it or against its properties now due
and payable, the failure to file or pay which, as applicable, would have a
Material Adverse Effect, unless and to the extent only that the same are being
contested in good faith and by appropriate proceedings by the Borrower or the
appropriate Subsidiary.

          (h) Except to the extent permitted pursuant to Section 5.02(e),
neither the Borrower nor any Material Subsidiary is subject to any contractual
restrictions which limit the amount of dividends payable by any Subsidiary.

          (i) No Termination Event has occurred or is reasonably expected to
occur with respect to any Plan which, with the giving of notice or lapse of
time, or both, would constitute an Event of Default under Section 6.01(g).

          (j) Neither the Borrower nor any ERISA Affiliate has incurred, or is
reasonably expected to incur, any Withdrawal Liability to any Multiemployer Plan
that, when aggregated with all other amounts required to be paid to
Multiemployer Plans in connection with Withdrawal Liability (as of the date of
determination), exceeds 5% of the Consolidated Tangible Net Worth of the
Borrower.

          (k) Neither the Borrower nor any ERISA Affiliate has received any
notification that any Multiemployer Plan is in reorganization or has been
terminated, within the meaning of Title IV of ERISA, and no Multiemployer Plan
is reasonably expected to be in reorganization or to be terminated within the
meaning of Title IV of ERISA the effect of which reorganization or termination
would be the occurrence of an Event of Default under Section 6.01(i).

          (l) The Borrower is not an "investment company" or a "company"
controlled by an "investment company" within the meaning of the Investment
Company Act of 1940, as amended.

          (m) The Borrower is not a "holding company" or a "subsidiary company"
of a "holding company", or an "affiliate" of a "holding company" or of a
"subsidiary company" of a "holding company", or a "public utility" within the
meaning of the Public Utility Holding Company Act of 1935, as amended.

All representations and warranties made by the Borrower herein or made in any
certificate delivered pursuant hereto shall survive the making of the Advances
and the execution and delivery to the Lenders of this Agreement and the Notes.

                            COVENANTS OF THE BORROWER

         SECTION 5.1. Affirmative Covenants. So long as any Note or other amount
payable by the Borrower hereunder shall remain unpaid or any Lender 





                                       44
<PAGE>   49



shall have any Commitment hereunder, the Borrower will, unless the Majority
Lenders shall otherwise consent in writing:

          (a) PRESERVATION OF CORPORATE EXISTENCE, ETC. Preserve and maintain,
and cause each Material Subsidiary to preserve and maintain, its corporate
existence, rights (charter and statutory) and material franchises, except as
otherwise permitted by Section 5.02(c) or 5.02(d).

          (b) COMPLIANCE WITH LAWS, ETC. Comply, and cause each Subsidiary to
comply, in all material respects, with all applicable laws, rules, regulations
and orders (including all environmental laws and laws requiring payment of all
taxes, assessments and governmental charges imposed upon it or upon its property
except to the extent contested in good faith by appropriate proceedings) the
failure to comply with which would have a Material Adverse Effect.

          (c) VISITATION RIGHTS. At such reasonable times and intervals as the
Administrative Agent or any of the Lenders (other than Designated Bidders) may
desire, permit the Administrative Agent or any of the Lenders (other than
Designated Bidders) to visit the Borrower and to discuss the affairs, finances,
accounts and mineral reserve performance of the Borrower and any of its
Subsidiaries with officers of the Borrower and independent certified public
accountants of the Borrower and any of its Subsidiaries, provided that if an
Event of Default, or an event which with the giving of notice or the passage of
time, or both, would become an Event of Default, has occurred and is continuing,
the Administrative Agent or any Lender may, in addition to the other provisions
of this subsection (c) and at such reasonable times and intervals as the
Administrative Agent or any of the Lenders may desire, visit and inspect, under
guidance of officers of the Borrower, any properties significant to the
consolidated operations of the Borrower and its Subsidiaries, and to examine the
books and records of account (other than with respect to any mineral reserve
information that the Borrower determines to be confidential) of the Borrower and
any of its Subsidiaries and to discuss the affairs, finances and accounts of any
of the Borrower's Subsidiaries with any of the officers of such Subsidiary.

          (d) BOOKS AND RECORDS. Keep, and cause each of its Subsidiaries to
keep, proper books of record and account, in which full and correct entries
shall be made of all financial transactions and the assets and business of the
Borrower and each Subsidiary in accordance with generally accepted accounting
principles either (i) consistently applied or (ii) applied in a changed manner
that does not, under generally accepted accounting principles or public
reporting requirements applicable to the Borrower, either require disclosure in
the consolidated financial statements of the Borrower and its consolidated
Subsidiaries or require the consent of the accountants which (as required by
Section 5.03(b)) report on such 





                                       45
<PAGE>   50



financial statements for the fiscal year in which such change shall have
occurred, or (iii) applied in a changed manner not covered by clause (ii) above
provided such change shall have been disclosed to the Administrative Agent and
shall have been consented to by the accountants which (as required by Section
5.03(b)) report on the consolidated financial statements of the Borrower and its
consolidated Subsidiaries for the fiscal year in which such change shall have
occurred, provided that if any change referred to in clause (ii) or (iii) above
would not meet the standard set forth in clause (i) or (ii) of Section 1.03, the
Administrative Agent, the Lenders and the Borrower agree to amend the covenants
contained in Section 5.01 and 5.02 so that the relative protection afforded
thereby to the Lenders and the relative flexibility afforded thereby to the
Borrower will in substance be retained after such amendment, provided, however,
that until such amendment becomes effective hereunder, the covenants as set
forth herein shall remain in full force and effect and those accounting
principles applicable to the Borrower and its consolidated Subsidiaries which do
meet the standards set forth in clause (i) or (ii) of Section 1.03 shall be
applied to determine whether or not the Borrower is in compliance with such
covenants.

          (e) MAINTENANCE OF PROPERTIES, ETC. Maintain and preserve, and cause
each Material Subsidiary to maintain and preserve, all of its properties which
are used in the conduct of its business in good working order and condition,
ordinary wear and tear excepted, to the extent that any failure to do so would
have a Material Adverse Effect.

          (f) MAINTENANCE OF INSURANCE. Maintain, and cause each Material
Subsidiary to maintain, insurance with responsible and reputable insurance
companies or associations in such amounts and covering such risks as is usually
carried by companies engaged in similar businesses and owning similar properties
in the same general areas in which the Borrower or such Subsidiary operates.

         SECTION 5.2. Negative Covenants. So long as any Note or other amount
payable by the Borrower hereunder shall remain unpaid or any Lender shall have
any Commitment hereunder, the Borrower will not, unless the Majority Lenders
shall otherwise consent in writing:

          (a) LIENS, ETC. (i) Create, assume or suffer to exist, or permit any
Material Subsidiary to create, assume or suffer to exist, any Liens upon or with
respect to any of the Equity Interests in any Material Subsidiary, whether now

Subsidiary to create or assume, any Liens upon or with respect to any other
assets material to the consolidated operations of the Borrower and its
consolidated Subsidiaries taken as a whole securing the payment of Debt and

that the amount 




                                       46

of a Guaranty will be excluded to the extent the Debt Guaranteed thereby is
included in computing such aggregate amount)) exceeding the greater of (x)

                  or becomes a Subsidiary of the Borrower, or on assets of any
                  such Business Entity, to the extent that such Liens existed at
                  the time of such acquisition and were not placed thereon by or

                  Lien permitted by any of the foregoing clauses of this
                  Section, provided that the principal amount of such Debt or
                  Guaranty is not increased (except by the amount of costs
                  reasonably incurred in connection with the issuance thereof)
                  and such Debt or Guaranty is not secured by any additional
                  assets that would not have been permitted by this Section to

connection therewith,

                            (1) the sum (without duplication) of (i)

                  by a consolidated Subsidiary that is either a Subsidiary of
                  the Borrower as of the Original Effective Date or a Subsidiary

                  time was approximately $400,000,000, and any refinancing of
                  such Debt, in a principal amount not to exceed the principal
                  amount refinanced) and (ii) 30% of Consolidated Tangible Net

any Material Subsidiary to sell, lease or otherwise transfer (in either case,

being used for investment in, and/or the development of, Permitted Assets;
provided further that, no such sale, lease or other transfer shall be permitted
by the foregoing proviso unless either (1) after giving effect to such sale,
lease or other transfer, no Event of Default, and no event which with lapse of
time or the giving of notice, or both, would constitute an Event of Default,
shall have occurred and be continuing or (2) the Borrower or the relevant
Material Subsidiary, as the case may be, was contractually obligated, prior to
the occurrence of such Event of Default or event, to consummate such sale, lease
or other transfer.

of its Material Subsidiaries to merge or consolidate with any Person, except
that (i) such a Subsidiary may merge or consolidate with (or liquidate into) any
other Subsidiary or may merge or consolidate with (or liquidate into) the
Borrower, provided that (A) if such Material Subsidiary merges or consolidates
with (or liquidates into) the Borrower, the Borrower shall be the continuing or
surviving corporation, (B) if any such Material Subsidiary merges or
consolidates with (or liquidates into) any other Subsidiary of the Borrower, one
of such Subsidiaries is the surviving corporation and, if either such Subsidiary
is not wholly-owned by the Borrower, such merger or consolidation is on an arm's
length basis and (C) as a result of such merger or consolidation, no Event of
Default, and no event which with lapse of time or the giving of notice, or both,
would constitute an Event of Default, shall have occurred and be continuing, and
(ii) the Borrower or any Material Subsidiary may merge or consolidate with any
other corporation (that is, in addition to the Borrower or any Subsidiary of the
Borrower), provided that (A) if the Borrower merges or consolidates with any
such other corporation, the Borrower is the surviving corporation, (B) if any
Material Subsidiary merges or 




                                       49
<PAGE>   54


consolidates with any such other corporation, the surviving corporation is a
wholly-owned Material Subsidiary of the Borrower, and (C) if either the Borrower
or any Material Subsidiary merges or consolidates with any such other
corporation, after giving effect to such merger or consolidation no Event of
Default, and no event which with lapse of time or the giving of notice, or both,
would constitute an Event of Default, shall have occurred and be continuing.

          (e) DIVIDEND RESTRICTIONS. Create, or consent or agree to, or permit

restrictions, contained in any agreement or instrument relating to or evidencing
Debt, on any such Subsidiary's ability to pay dividends or to make advances to
the Borrower or any Subsidiary of the Borrower; provided, however, that this
subsection (e) shall not apply to any such restrictions (including any
extensions of the term of any thereof (by amendment, or continuation thereof in
any refinancing of the Debt to which such restriction relates, or otherwise))
applicable to the Equity Interests in any Subsidiary of the Borrower the Equity
Interests in which shall be hereafter acquired by the Borrower and which
restrictions are existing at the time such Subsidiary first becomes a Subsidiary
of the Borrower and are not placed thereon by or with the consent of the
Borrower in contemplation of such acquisition by the Borrower.

         SECTION 5.3. Reporting Requirements. So long as any Note shall remain
unpaid or any Lender shall have any Commitment hereunder, the Borrower will

accepted accounting principles by the chief financial officer of the Borrower
and accompanied by a certificate of such officer stating (i) that such
statements of income and cash flow and such balance sheet have been prepared in
accordance with generally accepted accounting principles, (ii) whether or not
such officer has knowledge of the occurrence of any Event of Default which is
continuing hereunder or of any event not theretofore remedied which with notice

                                       50
<PAGE>   55

years, a certificate of the chief financial officer of the Borrower stating (i)
whether or not such officer has knowledge of the occurrence of any Event of
Default which is continuing hereunder or of any event not theretofore remedied
which with notice or lapse of time or both would constitute such an Event of
Default and, if so, stating in reasonable detail the facts with respect thereto,
(ii) all relevant facts in reasonable detail to evidence, and the computations
as to, whether or not the Borrower is in compliance with the requirements set
forth in subsection (g) of Section 5.01 and in subsection (b) of Section 5.02

or any Material Subsidiary, except any litigation or proceeding which in the
reasonable judgment of the Borrower (taking into account the exhaustion of all
appeals) is not likely to have a material adverse effect on the consolidated
financial condition of the Borrower and its consolidated Subsidiaries taken as a
whole;

          (g) within three Business Days after an executive officer of the
Borrower obtains knowledge of the occurrence of any Event of Default which is

Borrower of the steps being taken by the Borrower or the appropriate Subsidiary

         SECTION 7.1. Authorization and Action. Each Lender hereby appoints and
authorizes the Administrative Agent to take such action as agent on its behalf
and to exercise such powers under this Agreement as are delegated to the
Administrative Agent by the terms hereof, together with such powers as are
reasonably incidental thereto. As to any matters not expressly provided for by
this Agreement (including enforcement of this Agreement or collection of the





                                       56
<PAGE>   61



Notes), the Administrative Agent shall not be required to exercise any
discretion or take any action, but shall be required to act or to refrain from
acting (and shall be fully protected in so acting or refraining from acting)
upon the instructions of the Majority Lenders, and such instructions shall be
binding upon all Lenders and all holders of Notes; provided, however, that the
Administrative Agent shall not be required to take any action which exposes the
Administrative Agent to personal liability or which is contrary to this
Agreement or applicable law. The Administrative Agent agrees to give to each
Lender prompt notice of each notice given to it by the Borrower pursuant to the
terms of this Agreement.

         SECTION 7.2. Administrative Agent's Reliance, Etc.. Neither the
Administrative Agent nor any of its directors, officers, agents or employees
shall be liable for any action taken or omitted to be taken by it or them under

negligence or willful misconduct. Without limitation of the generality of the
foregoing, the Administrative Agent: (i) may treat the payee of any Note as the
holder thereof until the Administrative Agent receives and accepts an Assignment
and Acceptance entered into by the Lender which is the payee of such Note, as
assignor, and an Eligible Assignee, as assignee, as provided in Section 8.07;
(ii) may consult with legal counsel (including counsel for the Borrower),
independent public accountants and other experts selected by it and shall not be
liable for any action taken or omitted to be taken in good faith by it in

Lender for any statements, warranties or representations (whether written or
oral) made in or in connection with this Agreement; (iv) shall not have any duty

terms, covenants or conditions of this Agreement on the part of the Borrower or
to inspect the property (including the books and records) of the Borrower; (v)
shall not be responsible to any Lender for the due execution, legality,
validity, enforceability, genuineness, sufficiency or value of this Agreement or
any other instrument or document furnished pursuant hereto; and (vi) shall incur
no liability under or in respect of this Agreement by acting upon any notice,
consent, certificate or other instrument or writing (which may be by telegram,
telecopy, cable or telex) believed by it to be genuine and signed or sent by the
proper party or parties.

         SECTION 7.3. Morgan and Affiliates. With respect to its Commitments,
the Advances made by it and the Notes issued to it, Morgan shall have the same
rights and powers under this Agreement as any other Lender and may exercise the
same as though it were not the Administrative Agent; and the term "Lender" or
"Lenders" shall, unless otherwise expressly indicated, include Morgan in its
individual capacity. Morgan and its affiliates may accept deposits from, lend
money to, act as trustee under indentures of, and generally engage in any kind
of 




                                       57
<PAGE>   62



business with, the Borrower, any of its Subsidiaries and any Person who may do
business with or own securities of the Borrower or any Subsidiary, all as if
Morgan were not the Administrative Agent and without any duty to account
therefor to the other Lenders.

         SECTION 7.4. Lender Credit Decision. Each Lender acknowledges that it
has, independently and without reliance upon the Administrative Agent or any
other Lender and based on the financial statements referred to in Section 4.01
and such other documents and information as it has deemed appropriate, made its
own credit analysis and decision to enter into this Agreement. Each Lender also
acknowledges that it will, independently and without reliance upon the
Administrative Agent or any other Lender and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit decisions in taking or not taking action under this Agreement.

         SECTION 7.5. Indemnification. THE LENDERS (OTHER THAN THE DESIGNATED
BIDDERS) AGREE TO INDEMNIFY THE ADMINISTRATIVE AGENT (TO THE EXTENT NOT
REIMBURSED BY THE BORROWER), RATABLY ACCORDING TO THE RESPECTIVE PRINCIPAL
AMOUNTS OF THE NOTES THEN HELD BY EACH OF THEM (OR IF NO NOTES ARE AT THE TIME
OUTSTANDING OR IF ANY NOTES ARE HELD BY PERSONS WHICH ARE NOT LENDERS, RATABLY
ACCORDING TO THE RESPECTIVE AMOUNTS OF THEIR COMMITMENTS OR THE RESPECTIVE
AMOUNTS OF THEIR COMMITMENTS IMMEDIATELY PRIOR TO TERMINATION IF THE COMMITMENTS
HAVE BEEN TERMINATED), FROM AND AGAINST ANY AND ALL LIABILITIES, OBLIGATIONS,
LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES AND
DISBURSEMENTS OF ANY KIND OR NATURE WHATSOEVER WHICH MAY BE IMPOSED ON, INCURRED
BY, OR ASSERTED AGAINST THE ADMINISTRATIVE AGENT IN ANY WAY RELATING TO OR
ARISING OUT OF THIS AGREEMENT, ANY OF THE NOTES OR ANY OTHER INSTRUMENT OR
DOCUMENT FURNISHED PURSUANT HERETO OR IN CONNECTION HEREWITH, OR ANY ACTION
TAKEN OR OMITTED BY THE ADMINISTRATIVE AGENT UNDER THIS AGREEMENT, OR ANY OF THE
NOTES OR ANY OTHER INSTRUMENT OR DOCUMENT FURNISHED PURSUANT HERETO OR IN
CONNECTION HEREWITH; PROVIDED THAT NO LENDER SHALL BE LIABLE FOR ANY PORTION OF
SUCH LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS,
SUITS, COSTS, EXPENSES OR DISBURSEMENTS RESULTING FROM THE ADMINISTRATIVE
AGENT'S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.

<PAGE>   63




Without limitation of the foregoing, each Lender (other than the Designated
Bidders) agrees to reimburse the Administrative Agent promptly upon demand for
such Lender's ratable share of any reasonable out-of-pocket expenses (including
counsel fees) incurred by the Administrative Agent in connection with the
preparation, execution, delivery, administration, modification, amendment or
enforcement (whether through negotiations, legal proceedings, in bankruptcy or
insolvency proceedings, or otherwise) of, or legal advice in respect of rights
or responsibilities under, this Agreement, any of the Notes or any other
instrument or document furnished pursuant hereto or in connection herewith to
the extent that the Administrative Agent acts in its capacity as Administrative
Agent and is not reimbursed for such expenses by the Borrower.

         SECTION 7.6. Successor Administrative Agent. The Administrative Agent
may resign at any time by giving written notice thereof to the Lenders and the
Borrower and may be removed at any time with or without cause by the Majority
Lenders. Upon any such resignation or removal, the Majority Lenders shall have
the right to appoint a successor Administrative Agent. If no successor
Administrative Agent shall have been so appointed by the Majority Lenders, and
shall have accepted such appointment, within 30 days after the retiring
Administrative Agent's giving of notice of resignation or the Majority Lenders'
removal of the retiring Administrative Agent, then such retiring Administrative
Agent may, on behalf of the Lenders, appoint a successor Administrative Agent,
which shall be a commercial bank organized, or authorized to conduct a banking
business, under the laws of the United States of America or of any State thereof
and having a combined capital and surplus of at least $500,000,000. Upon the
acceptance of any appointment as Administrative Agent hereunder by a successor
Administrative Agent, such successor Administrative Agent shall thereupon
succeed to and become vested with all the rights, powers, privileges and duties
of the retiring Administrative Agent, and the retiring Administrative Agent
shall be discharged from its duties and obligations under this Agreement. After
any retiring Administrative Agent's resignation or removal hereunder as
Administrative Agent, the provisions of this Article 7 shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was
Administrative Agent under this Agreement.

the Notes if, but only if, it shall be in writing and signed by the Majority
Lenders or the Required Lenders, as applicable (except any amendment to give
effect to Increased Commitments and Additional Lenders, as contemplated by
Section 2.20), and then such a waiver or consent shall be effective only in the
specific instance and for the specific purpose for which given; provided,
however, that no such amendment, waiver or consent shall, unless in writing and
signed by all the Lenders (other than the Designated Bidders), be effective to:

authorized representative of the Borrower and acts pursuant thereto,
notwithstanding the absence of written confirmation or any contradictory
provision thereof.

         SECTION 8.3. No Waiver; Remedies. No failure on the part of any Lender
or the Administrative Agent to exercise, and no delay in exercising, any right

          (b) If any payment of principal of, or Conversion of, any Eurodollar

pursuant to Section 6.01 or due to any other reason attributable to the
Borrower, the Borrower shall, upon demand by such Lender (with a copy of such
demand to the Administrative Agent), pay to the Administrative Agent for the
account of such Lender any amounts required to compensate such Lender for any

demand, provisional or final) at any time held and other indebtedness at any
time owing by such Lender to or for the credit or the account of the Borrower
against any and all of the obligations of the Borrower now or hereafter existing

Short-Term Revolving Credit Agreement, unless the Short-Term Revolving Credit
Agreement has been terminated, shall be contemporaneously assigned by such
assigning Lender to the same assignee pursuant to Section 8.07(a) of the
Short-Term Revolving Credit Agreement, (ii) the sum of (x) the amount of the
Commitment of the assigning Lender being assigned to the assignee pursuant to
each such assignment (determined as of the date of the Assignment and Acceptance
with respect to such assignment) plus (y) the amount of the "Commitment" of the
assigning Lender under the Short-Term Revolving Credit Agreement
contemporaneously assigned by such assigning Lender to such assignee as
contemplated by clause (i) of this sentence must be equal to or greater than
$25,000,000 (unless the Borrower and the Administrative Agent shall otherwise
consent, which consent may be withheld for any reason) and must be an integral
multiple of $1,000,000, (iii) each such assignment shall be to an Eligible
Assignee, and (iv) the parties to each such assignment shall execute and deliver
to the Administrative Agent, for its acceptance and recording in the Register,
an Assignment and Acceptance, together with any Note or Notes subject to such
assignment and a processing and recordation fee of $3,000, and shall send to the
Borrower an executed counterpart of such Assignment and Acceptance. Upon such
execution, delivery, acceptance and recording, from and after the effective date
specified in each Assignment and Acceptance, (x) the assignee thereunder shall
be a party hereto and, to the extent that rights and obligations hereunder have
been assigned to it pursuant to such Assignment and Acceptance, have the rights
and obligations of a Lender hereunder and (y) the Lender assignor thereunder
shall, to the extent that rights 





                                       63
<PAGE>   68



and obligations hereunder have been assigned by it pursuant to such Assignment
and Acceptance, relinquish its rights and be released from its obligations under
this Agreement (and, in the case of an Assignment and Acceptance covering all or
the remaining portion of an assigning Lender's rights and obligations under this
Agreement, such Lender shall cease to be a party hereto, provided, however, such
assigning Lender shall retain any claim with respect to any fee, interest, cost,
expense or indemnity which accrues, or relates to an event that occurs, prior to
the date of such assignment pursuant to Section 2.03, 2.06, 2.07, 2.11, 2.12,
2.15 or 8.04).

          (b) By executing and delivering an Assignment and Acceptance, each
Lender assignor thereunder and the assignee thereunder confirm to and agree with
each other and the other parties hereto as follows: (i) other than as provided
in such Assignment and Acceptance, such assigning Lender makes no representation
or warranty and assumes no responsibility with respect to any statements,
warranties or representations made in or in connection with this Agreement or
the execution, legality, validity, enforceability, genuineness, sufficiency or
value of this Agreement or any other instrument or document furnished pursuant
hereto; (ii) such assigning Lender makes no representation or warranty and
assumes no responsibility with respect to the financial condition of the
Borrower or the performance or observance by the Borrower of any of its
obligations under this Agreement or any other instrument or document furnished
pursuant hereto; (iii) such assignee confirms that it has received a copy of
this Agreement, together with copies of the financial statements referred to in
Section 4.01 and such other documents and information as it has deemed
appropriate to make its own credit analysis and decision to enter into such
Assignment and Acceptance; (iv) such assignee will, independently and without
reliance upon the Administrative Agent, such assigning Lender or any other
Lender and based on such documents and information as it shall deem appropriate
at the time, continue to make its own credit decisions in taking or not taking
action under this Agreement; (v) such assignee confirms that it is (subject to
approval in writing by the Borrower and the Administrative Agent to the extent
required) an Eligible Assignee; (vi) such assignee appoints and authorizes the
Administrative Agent to take such action as agent on its behalf and to exercise
such powers under this Agreement as are delegated to the Administrative Agent by
the terms hereof, together with such powers as are reasonably incidental
thereto; and (vii) such assignee agrees that it will perform in accordance with
their terms all of the obligations which by the terms of this Agreement are
required to be performed by it as a Lender.

          (c) The Administrative Agent shall maintain at its address referred to
in Section 8.02 a copy of each Assignment and Acceptance, each Designation
Agreement, each New Lender Agreement and each Commitment Increase Agreement
delivered to and accepted by it and a register for the recordation of the 






                                       64
<PAGE>   69



names and addresses of the Lenders and, with respect to Lenders other than
Designated Bidders, the Commitment of, and principal amount of the A Advances
owing to, each Lender from time to time (the "REGISTER"). The entries in the
Register shall be conclusive and binding for all purposes, absent manifest
error, and the Borrower, the Administrative Agent and the Lenders may treat each
Person whose name is recorded in the Register as a Lender hereunder for all
purposes of this Agreement. The Register shall be available for inspection by
the Borrower or any Lender at any reasonable time and from time to time upon
reasonable prior notice.

          (d) Upon its receipt of an Assignment and Acceptance executed by an
assigning Lender and an assignee representing that it is an Eligible Assignee,
together with any Note or Notes subject to such assignment, the Administrative
Agent shall, if such Assignment and Acceptance has been completed and is in
substantially the form of Exhibit D hereto, (i) accept such Assignment and
Acceptance, (ii) record the information contained therein in the Register and
(iii) give prompt notice thereof to the Borrower. Within five Business Days
after its receipt of such notice and its receipt of an executed counterpart of
such Assignment and Acceptance, the Borrower, at its own expense, shall execute
and deliver to the Administrative Agent in exchange for the surrendered Note or
Notes a new Note to the order of such Eligible Assignee and, if the assigning
Lender has retained a Commitment hereunder, a new Note to the order of the
assigning Lender. Such new Note or Notes shall be dated the effective date of
such Assignment and Acceptance and shall otherwise be in substantially the form
of Exhibit A hereto.

          (e) Each Lender (other than a Designated Bidder) may designate one or
more banks or other entities to have a right to make B Advances as a Lender
pursuant to Section 2.19; provided that (i) such Lender shall have obtained the
written consent of the Administrative Agent and the Borrower, such consent not
to be unreasonably withheld, (ii) no such Lender shall be entitled to make more
than two such designations, (iii) each such Lender making one or more of such
designations shall retain the right to make B Advances as a Lender pursuant to
Section 2.19, (iv) each such designation shall be to a Designated Bidder and (v)
the parties to each such designation shall execute and deliver to the
Administrative Agent, for its acceptance and recording in the Register, a
Designation Agreement. Upon such execution, delivery, acceptance and recording,
from and after the effective date specified in each Designation Agreement, the
designee thereunder shall be a party hereto with a right to make B Advances as a
Lender pursuant to Section 2.19 and the obligations related thereto.

          (f) By executing and delivering a Designation Agreement, the Lender
making the designation thereunder and its designee thereunder confirm and agree
with each other and the other parties hereto as follows: (i) such Lender makes
no 




                                       65
<PAGE>   70


representation or warranty and assumes no responsibility with respect to any
statements, warranties or representations made in or in connection with this
Agreement or the execution, legality, validity, enforceability, genuineness,
sufficiency or value of this Agreement or any other instrument or document
furnished pursuant hereto, (ii) such Lender makes no representation or warranty
and assumes no responsibility with respect to the financial condition of the
Borrower or the performance or observance by the Borrower of any of its
obligations under this Agreement or any other instrument or document furnished
pursuant hereto; (iii) such designee confirms that it has received a copy of
this Agreement, together with copies of the financial statements referred to in
Section 4.01 and such other documents and information as it has deemed
appropriate to make its own credit analysis and decision to enter into the
Designation Agreement; (iv) such designee will, independently and without
reliance upon the Administrative Agent, such designating Lender or any other
Lender and based on such documents and information as it shall deem appropriate
at the time, continue to make its own credit decisions in taking or not taking
action under this Agreement; (v) such designee confirms that it is a Designated
Bidder; (vi) such designee appoints and authorizes the Administrative Agent to
take such action as agent on its behalf and to exercise such powers under this
Agreement as are delegated to the Administrative Agent by the terms hereof,
together with such powers as are reasonably incidental thereto, and (vii) such
designee agrees that it will perform in accordance with their terms all of the
obligations which by the terms of this Agreement are required to be performed by
it as a Lender.

          (g) Upon its receipt of a Designation Agreement executed by a
designating Lender and a designee representing that it is a Designated Bidder,
the Administrative Agent shall, if such Designation Agreement has been completed
and is substantially in the form of Exhibit K hereto, (i) accept such
Designation Agreement, (ii) record the information contained therein in the
Register and (iii) give prompt notice thereof to the Borrower.

          (h) Each Lender may sell participations to one or more banks or other
entities in or to all or a portion of its rights and obligations under this
Agreement (including all or a portion of its Commitment, and the Advances owing
to it and the Note or Notes held by it); provided, however, that (i) such
Lender's obligations under this Agreement (including its Commitment to the
Borrower hereunder) shall remain unchanged, (ii) such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations,
(iii) such Lender shall remain the holder of any such Note for all purposes of
this Agreement, (iv) the Borrower, the Administrative Agent and the other
Lenders shall continue to deal solely and directly with such Lender in
connection with such Lender's rights and obligations under this Agreement, (v)
such Lender shall 






                                       66
<PAGE>   71


continue to be able to agree to any modification or amendment of this Agreement
or any waiver hereunder without the consent, approval or vote of any such
participant or group of participants, other than modifications, amendments and
waivers which (A) postpone any date fixed for any payment of, or reduce any
payment of, principal of or interest on such Lender's Note or any facility fees
payable under this Agreement, or (B) increase the amount of such Lender's
Commitment in a manner which would have the effect of increasing the amount of a
participant's participation, or (C) reduce the interest rate payable under this
Agreement and such Lender's Note, or (D) consent to the assignment or the
transfer by the Borrower of any of its rights and obligations under the
Agreement, and (vi) except as contemplated by the immediately preceding clause
(v), no participant shall be deemed to be or to have any of the rights or
obligations of a "Lender" hereunder.

          (i) Any Lender may, in connection with any assignment, designation or
participation or proposed assignment, designation or participation pursuant to
this Section 8.07, disclose to the assignee, designee or participant or proposed
assignee, designee or participant, any information relating to the Borrower
furnished to such Lender by or on behalf of the Borrower; provided that, prior
to any such disclosure, the assignee, designee or participant or proposed
assignee, designee or participant shall agree in writing for the benefit of the
Borrower to preserve the confidentiality of any confidential information
relating to the Borrower received by it from such Lender in a manner consistent
with Section 8.08.

          (j) Anything in this Agreement to the contrary notwithstanding, any
Lender may at any time create a security interest in all or any portion of its
rights under this Agreement (including the Advances owing to it) and the Notes
issued to it hereunder in favor of any Federal Reserve Bank in accordance with
Regulation A of the Board of Governors of the Federal Reserve System (or any
successor regulation) and the applicable operating circular of such Federal
Reserve Bank.

         SECTION 8.8. Confidentiality. Each Lender and the Administrative Agent
(each, a "PARTY") agrees that it will use its best reasonable efforts not to
disclose, without the prior consent of the Borrower (other than to its, or its
Affiliates, employees, auditors, accountants, counsel or other representatives,
whether existing at the date of this Agreement or any subsequent time), any
information with respect to the Borrower which is furnished pursuant to this
Agreement, provided that any party may disclose any such information (i) as has
become generally available to the public, (ii) as may be required or appropriate
in any report, statement or testimony submitted to any municipal, state or
Federal regulatory body having or claiming to have jurisdiction over such party
or to the 




                                       67
<PAGE>   72



Board of Governors of the Federal Reserve System or the Federal Deposit
Insurance Corporation or similar organizations (whether in the United States or
elsewhere) or their successors, (iii) as may be required or appropriate in
response to any summons or subpoena or in connection with any litigation or
regulatory proceeding, (iv) in order to comply with any law, order, regulation
or ruling applicable to such party, or (v) to any prospective assignee, designee
or participant in connection with any contemplated assignment of any rights or
obligations hereunder, any designation or any sale of any participation therein,
by such party pursuant to Section 8.07, if such prospective assignee, designee
or participant, as the case may be, executes an agreement with the Borrower
containing provisions substantially similar to those contained in this Section
8.08; provided, however, that the Borrower acknowledges that the Administrative
Agent has disclosed and may continue to disclose such information as the
Administrative Agent in its sole discretion determines is appropriate to the
Lenders from time to time.

         SECTION 8.9.  Consent to Jurisdiction.

          (a) The Borrower hereby irrevocably submits to the jurisdiction of any
New York State or Federal court sitting in New York City and any appellate court
from any thereof in any action or proceeding by the Administrative Agent, the
Arranger, any Lender or the holder of any Note in respect of, but only in
respect of, any claims or causes of action arising out of or relating to this
Agreement or the Notes (such claims and causes of action, collectively, being
"PERMITTED CLAIMS"), and the Borrower hereby irrevocably agrees that all
Permitted Claims may be heard and determined in such New York State court or in
such Federal court. The Borrower hereby irrevocably waives, to the fullest
extent it may effectively do so, the defense of an inconvenient forum to the
maintenance of such action or proceeding in any aforementioned court in respect
of Permitted Claims. Service of the summons and complaint and any other process
which may be served by the Administrative Agent, the Arranger, any Lender or the
holder of any Note on the Borrower in any such action or proceeding in any
aforementioned court in respect of Permitted Claims may be made by delivering
separate copies of such process to the Borrower by courier and by certified mail
(return receipt requested), fees and postage prepaid at the Borrower's address
specified pursuant to Section 8.02, to the attention of each of the Treasurer
and the Executive Vice President, Law. The Borrower agrees that a final judgment
in any such action or proceeding shall be conclusive and may be enforced in
other jurisdictions by suit on the judgment or in any other manner provided by
law.

          (b) Nothing in this Section 8.09 (i) shall affect the right of the
Arranger, the Borrower, any Lender, the holder of any Note or the Administrative
Agent to serve legal process in any other manner permitted by law or affect any
right 





                                       68
<PAGE>   73




otherwise existing of the Borrower, any Lender, the Arranger, the holder of any
Note or the Administrative Agent to bring any action or proceeding in the courts
of other jurisdictions or (ii) shall be deemed to be a general consent to
jurisdiction in any particular court or a general waiver of any defense or a
consent to jurisdiction of the courts expressly referred to in subsection (a)
above in any action or proceeding in respect of any claim or cause of action
other than Permitted Claims.

         SECTION 8.10. Governing Law. This Agreement and the Notes shall be
governed by, and construed in accordance with, the laws of the State of New
York.

         SECTION 8.11. Execution in Counterparts. This Agreement may be executed
in any number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed shall be deemed to be an original
and all of which taken together shall constitute one and the same agreement.
Delivery to the Administrative Agent of a counterpart executed by a Lender shall
constitute delivery of such counterpart to all of the Lenders.

         SECTION 8.12. WAIVER OF JURY TRIAL. THE BORROWER, THE ADMINISTRATIVE
AGENT, AND THE LENDERS HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE ANY AND ALL
RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO
THIS AGREEMENT, ANY OF THE NOTES OR ANY OTHER INSTRUMENT OR DOCUMENT FURNISHED
PURSUANT HERETO OR IN CONNECTION HEREWITH OR THE TRANSACTIONS CONTEMPLATED
HEREBY.

The applicable pricing level shall change on the date of any relevant change in
the rating by S&P or Moody's of any public long term senior unsecured debt
securities of the Borrower. In the case of split ratings from S&P and Moody's,
the rating to be used to determine the applicable pricing level is the higher of
the two (e.g., A-/Baa1 results in Level II pricing), provided that in the event
the split is more than one full category, the average (or the higher of two
intermediate ratings) shall be used (e.g., A-/Baa2 results in Level III pricing,
as does A-/Baa3).

                                     FORM OF
               OPINION OF SENIOR VICE PRESIDENT, LAW FOR BORROWER



February ____, 1998


To each of the Lenders and the Agents
  Referred to Below
c/o Morgan Guaranty Trust Company of New York
60 Wall Street, 22nd Floor
New York, New York  10260


Ladies and Gentlemen:

This opinion is furnished to you pursuant to Section 3.01(d) of the Long-Term
Revolving Credit Agreement, dated as of February 25, 1998 (the "Credit
Agreement"), among Burlington Resources Inc., a Delaware corporation (the
"Borrower"), the financial institutions party thereto (each a "Lender," and
together the "Lenders"), Morgan Guaranty Trust Company of New York, as
Administrative Agent for the Lenders, Citibank, N.A., as Syndication Agent, and
Chase Bank of Texas, N.A. and NationsBank of Texas, N.A., as Co-Documentation
Agents. Unless the context otherwise requires, all capitalized terms used herein
without definition shall have the meanings ascribed to them in the Credit
Agreement.

I am Senior Vice President, Law of the Borrower, and I, or attorneys over whom I
exercise supervision, have acted as counsel for the Borrower in connection with
the preparation, execution and delivery of the Credit Agreement. In that
connection, I or such attorneys have examined:

                (1)      The Credit Agreement, executed by the parties thereto;

                (2)      The Notes executed by the Borrower; and

                (3)      The other documents furnished by the Borrower pursuant 
                         to Section 3.01 of the Credit Agreement.

I, or attorneys over whom I exercise supervision, have also examined the
originals, or copies certified to our satisfaction, of the agreements,
instruments and other documents, and all of the orders, writs, judgments,
awards, injunctions and decrees, which affect or purport to affect the






<PAGE>   102



Borrower's ability to perform the Borrower's obligations under the Credit
Agreement or the Notes (collectively referred to herein as the "Documents"). In
addition, I, or attorneys over whom I exercise supervision, have examined the
originals, or copies certified to our satisfaction, of such other corporate
records of the Borrower, certificates of public officials and of officers of the
Borrower, and agreements, instruments and other documents, as I have deemed
necessary as a basis for the opinions hereinafter expressed. In all such
examinations, I, or attorneys over whom I exercise supervision, have assumed the
legal capacity of all natural persons executing documents, the genuineness of
all signatures on original or certified, conformed or reproduction copies of
documents of all parties (other than, with respect to the Documents, the
Borrower), the authenticity of original and certified documents and the
conformity to original or certified copies of all copies submitted to such
attorneys or me as conformed or reproduction copies. As to various questions of
fact relevant to the opinions expressed herein, I have relied upon, and assume
the accuracy of, representations and warranties contained in the Credit
Agreement and certificates and oral or written statements and other information
of or from public officials, officers and/or representatives of the Borrower and
others.

To the extent it may be relevant to the opinions expressed herein, I have
assumed that the parties to the Documents other than the Borrower have the power
to enter into and perform such documents and that such documents have been duly
authorized, executed and delivered by, and constitute legal, valid and binding
obligations of, such parties.

The opinions expressed below are limited to the federal laws of the United
States and, to the extent relevant hereto, the General Corporation Law of the
State of Delaware, as currently in effect. I assume no obligation to supplement
this opinion if any applicable laws change after the date hereof or if I become
aware of any facts that might change the opinions expressed herein after the
date hereof.

Based upon the foregoing and upon such investigation as I have deemed necessary,
and subject to the limitations, qualifications and assumptions set forth herein,
I am of the following opinion:

     1.  The Borrower (i) is a corporation duly incorporated and existing in
         good standing under the laws of the State of Delaware, and (ii)
         possesses all the corporate powers and all other authorizations and
         licenses necessary to engage in its business and operations as now
         conducted, the failure to obtain or maintain which would have a
         Material Adverse Effect.

     2.  The execution, delivery and performance by the Borrower of the
         Documents are within the Borrower's corporate powers and have been duly
         authorized by all necessary corporate action in respect of or by the
         Borrower (except to the extent that the Borrower seeks to exercise its
         right under Section 2.20 of the Credit Agreement to effect an increase
         of Commitments), and do not contravene (i) the Borrower's Certificate
         of Incorporation or By-Laws, in each case as amended, (ii) any federal
         law, rule or regulation applicable to the Borrower (excluding
         provisions of federal law expressly referred to in and covered by the
         opinion of Jones, Day, Reavis & Pogue delivered to you in connection
         with the transactions 






<PAGE>   103

         contemplated hereby), or (iii) any contractual restriction binding on 
         or affecting the Borrower. The Documents have been duly executed and
         delivered on behalf of the Borrower.

     3.  No authorization or approval or other action by, and no notice to or
         filing with, any federal governmental authority or regulatory body
         (including, without limitation, the Federal Energy Regulatory
         Commission) is required for the due execution, delivery and performance
         by the Borrower of the Documents, except those required in the ordinary
         course of business in connection with the performance by the Borrower
         of its obligations under certain covenants and warranties contained in
         the Documents.

     4.  To the best of my knowledge, there is no action, suit or proceeding
         pending or overtly threatened against or involving the Borrower or any
         of its Material Subsidiaries, which, in my reasonable judgment (taking
         into account the exhaustion of all appeals), would have a material
         adverse effect upon the consolidated financial condition of the
         Borrower and its consolidated Subsidiaries taken as a whole, or which
         purports to affect the legality, validity, binding effect or
         enforceability of any Document.

These opinions are given as of the date hereof and are solely for your benefit
in connection with the transactions contemplated by the Credit Agreement. These
opinions may not be relied upon by you for any other purpose or relied upon by
any other person for any purpose without my prior written consent.


Very truly yours,



L. David Hanower
Senior Vice President, Law

                              COUNSEL FOR BORROWER

                                                               February __, 1998

To Each of the Lenders and the Administrative Agent
  Referred to Below
c/o Morgan Guaranty Trust Company of New York
60 Wall Street, 22nd Floor
New York, New York 10260

      Re:   Long-Term Revolving Credit Agreement, dated as of February 25, 1998

Ladies and Gentlemen:

         We have acted as special New York counsel for Burlington Resources
Inc., a Delaware corporation (the "Borrower"), in connection with the Long-Term
Revolving Credit Agreement, dated as of February __, 1998 (the "Credit
Agreement"), among the Borrower, the financial institutions party thereto (each
a "Lender," and together the "Lenders"), and Morgan Guaranty Trust Company of
New York, as Administrative Agent for the Lenders, Citibank, N.A., as
Syndication Agent for the Lenders, and Chase Bank of Texas, N.A. and NationsBank
of Texas, N.A., as Co-Documentation Agents for the Lenders. This opinion is
delivered to you pursuant to Section 3.01(e) of the Credit Agreement. All
capitalized terms used herein that are defined in, or by reference in, the
Credit Agreement have the meanings assigned to such terms therein, or by
reference therein, unless otherwise defined herein. With your permission, all
assumptions and statements of reliance herein have been made without any
independent investigation or verification on our part except to the extent
otherwise expressly stated, and we express no opinion with respect to the
subject matter or accuracy of such assumptions or items relied upon.

         In connection with this opinion, we have (i) investigated such
questions of law, (ii) examined originals or certified, conformed or
reproduction copies of such documents, and (iii) received such information from
officers and representatives of the Borrower as we have deemed necessary or
appropriate for the purposes of this opinion. We have examined, among other
documents, the following:

         (a) A facsimile of an executed copy of the Credit Agreement;

         (b) A facsimile of an executed copy of each of the __ Notes; and

         (c) A facsimile of the Officer's Certificate of the Borrower delivered
             to us in connection with this opinion, a copy of which is attached 
             hereto as Annex A.



<PAGE>   105



The documents referred to in items (a) and (b) above are referred to herein
collectively as the "Documents."

         In all such examinations, we have assumed the legal capacity of all
natural persons executing documents, the genuineness of all signatures, the
authenticity of original and certified documents and the conformity to original
or certified copies of all copies submitted to us as conformed or reproduction
copies. As to various questions of fact relevant to the opinions expressed
herein, we have relied upon, and assume the accuracy of, representations and
warranties contained in the Documents and certificates and oral or written
statements and other information of or from representatives of the Borrower and
others. With respect to the opinions expressed in paragraph (a) below, our
opinions are limited (x) to our actual knowledge of the Borrower's specially
regulated business activities and properties based solely upon an officer's
certificate in respect of such matters and without any independent investigation
or verification on our part and (y) to our review of only those laws and
regulations that, in our experience, are normally applicable to transactions of
the type contemplated by the Documents.

         To the extent it may be relevant to the opinions expressed herein, we
have assumed that the parties to the Documents other than the Borrower have the
power to enter into and perform such documents and that such documents have been
duly authorized, executed and delivered by, and constitute legal, valid and
binding obligations of, such parties.

         Based upon the foregoing, and subject to the limitations,
qualifications and assumptions set forth herein, we are of the opinion that:

         (a) The execution and delivery to the Administrative Agent and the
Lenders by the Borrower of the Documents and the performance by the Borrower of
its obligations thereunder (i) do not require under present law any filing or
registration by the Borrower with, or approval or consent to the Borrower of,
any governmental agency or authority of the State of New York, except those, if
any, required in the ordinary course of business in connection with the
performance by the Borrower of its obligations under certain covenants and
warranties contained in the Documents and (ii) do not violate any present law,
or present regulation of any governmental agency or authority, of the State of
New York applicable to the Borrower or its property.

         (b) The Documents constitute the legal, valid and binding obligations
of the Borrower enforceable against the Borrower in accordance with their
respective terms.

         (c) The borrowings by the Borrower under the Credit Agreement and the
applications of the proceeds thereof as provided in the Credit Agreement will
not violate Regulation G, T, U or X of the Board of Governors of the Federal
Reserve System.

         The opinions set forth above are subject to the following
qualifications:

         (A) We express no opinion as to:



<PAGE>   106



                      (i) the validity, binding effect or enforceability (a) of
         any provision of the Documents relating to indemnification,
         contribution or exculpation in connection with violations of any
         securities laws or statutory duties or public policy, or in connection
         with willful, reckless or criminal acts or gross negligence of the
         indemnified or exculpated party or the party receiving contribution; or
         (b) of any provision of any of the Documents relating to exculpation of
         any party in connection with its own negligence that a court would
         determine in the circumstances under applicable law to be unfair or
         insufficiently explicit;

                      (ii) the validity, binding effect or enforceability of (a)
         any purported waiver, release, variation, disclaimer, consent or other
         agreement to similar effect (all of the foregoing, collectively, a
         "Waiver") by the Borrower under the Documents to the extent limited by
         provisions of applicable law (including judicial decisions), or to the
         extent that such a Waiver applies to a right, claim, duty, defense or
         ground for discharge otherwise existing or occurring as a matter of law
         (including judicial decisions), except to the extent that such a Waiver
         is effective under and is not prohibited by or void or invalid under
         provisions of applicable law (including judicial decisions) or (b) any
         provision of any Document relating to choice of governing law to the
         extent that the validity, binding effect or enforceability of any such
         provision is to be determined by any court other than a court of the
         State of New York;

                      (iii) the enforceability of any provision in the Documents
         specifying that provisions thereof may be waived only in writing, to
         the extent that an oral agreement or an implied agreement by trade
         practice or course of conduct has been created that modifies any
         provision of the Documents;

                      (iv) the effect of any law of any jurisdiction other than
         the State of New York wherein the Administrative Agent or any Lender
         may be located or wherein enforcement of any document referred to above
         may be sought that limits the rates of interest legally chargeable or
         collectible; and

                      (v) any approval, consent or authorization of the Federal
         Energy Regulatory Commission or any other United States federal agency
         or authority needed in connection with the execution, delivery and
         performance by the Borrower of the Documents, the consummation of the
         transactions contemplated thereby and compliance with the terms and
         conditions thereof.

         (B) Our opinions above are subject to (i) applicable bankruptcy,
insolvency, reorganization, moratorium, fraudulent transfer or similar laws from
time to time in effect affecting creditors' rights generally, (ii) general
principles of equity (including, without limitation, standards of materiality,
good faith, fair dealing and reasonableness), whether such principles are
considered in a proceeding at law or in equity and (iii) the qualification that
certain other provisions of the Documents may be unenforceable in whole or in
part under the laws (including judicial decisions) of the State of New York or
the United States of America, but the 




<PAGE>   107



inclusion of such provisions does not affect the validity as against the
Borrower of the Documents as a whole, and the Documents contain adequate
provisions for enforcing payment of the obligations governed thereby, subject to
the other qualifications contained in this letter.

         (C) For purposes of the opinions set forth in paragraph (c) above, we
have assumed that (i) neither the Administrative Agent nor any of the Lenders
has or will have the benefit of any agreement or arrangement (excluding the
Documents) pursuant to which any Advances are directly or indirectly secured by
Margin Stock, (ii) neither the Administrative Agent nor any of the Lenders nor
any of their respective affiliates has extended or will extend any other credit
to the Borrower directly or indirectly secured by Margin Stock and (iii) neither
the Administrative Agent nor any of the Lenders has relied or will rely upon any
Margin Stock as collateral in extending or maintaining any Advances pursuant to
the Credit Agreement.

         (D) For purposes of our opinions above, insofar as they relate to the
Borrower, we have assumed that (i) the Borrower is a corporation validly
existing in good standing in its jurisdiction of incorporation, has all
requisite power and authority, and has obtained all requisite corporate,
shareholder, third party and governmental authorizations, consents and
approvals, and made all requisite filings and registrations, necessary to
execute, deliver and perform the Documents (except to the extent noted in
paragraph (a) above), and that such execution, delivery and performance will not
violate or conflict with any law, rule, regulation, order, decree, judgment,
instrument or agreement binding upon or applicable to the Borrower or its
properties (except to the extent noted in paragraph (a) above), and (ii) the
Documents have been duly executed and delivered by the Borrower.

         We express no opinion as to the effect of the compliance or
noncompliance of each of the addressees with any state or federal laws or
regulations applicable to each of them by reason of their status as or
affiliation with a federally insured depository institution, except as expressly
set forth in paragraph (c) above.

         The opinions expressed herein are limited to the federal laws of the
United States of America (in the case of the matters covered in paragraph (c)
above) and the laws of the State of New York (in the case of the matters covered
in paragraphs (a) and (b) above), as currently in effect.

         The opinions expressed herein are solely for the benefit of the
Administrative Agent and the Lenders and may not be relied on in any manner or
for any purpose by any other person or entity.

                                         Very truly yours,

Ladies and Gentlemen:

         We have participated in the preparation of the Long-Term Credit

counsel for the Administrative Agent for the purpose of rendering this opinion
pursuant to Section 3.01(f) of the Credit Agreement. Terms defined in the Credit
Agreement are used herein as therein defined.

         We have examined originals or copies, certified or otherwise identified
to our satisfaction, of such documents, corporate records, certificates of
public officials and other instruments and have conducted such other
investigations of fact and law as we have deemed necessary or advisable for
purposes of this opinion.

         Upon the basis of the foregoing, we are of the opinion that:

         1. The execution, delivery and performance by the Borrower of the
Credit Agreement and the Notes are within the Borrower's corporate powers and
have been duly authorized by all necessary corporate action.

         2. The Credit Agreement constitutes a valid and binding agreement of
the Borrower and each Note issued thereunder today constitutes a valid and
binding obligation of the Borrower, in each case enforceable in accordance with
its terms, subject to applicable bankruptcy, insolvency or similar laws
affecting creditors' rights generally and general principles of equity.

                           February 23, 1999 (this "Amendment and Restatement")
                           in respect of the LONG-TERM CREDIT AGREEMENT dated as
                           of February 25, 1998 (the "Credit Agreement"), among
                           BURLINGTON RESOURCES INC., a Delaware corporation
                           (the "Borrower"), the financial institutions (the
                           "Lenders") listed on the signature pages thereof,
                           Morgan Guaranty Trust Company of New York, as
                           administrative agent (in such capacity, the "Original
                           Administrative Agent") for the Lenders hereunder,
                           Citibank, N.A., as syndication agent for the Lenders,
                           and Chase Bank of Texas, N.A. ("Chase" and, in its
                           capacity as administrative agent for the Lenders, the

therewith that the Credit Agreement be amended and restated as set forth in
Section 1 below and the parties hereto are willing so to amend the Credit

         phrases of similar import, shall be deemed references to the Original
         Effective Date.

                  (e) Conforming References. All references in the Credit
         Agreement and the Exhibits to agents, to the Credit Agreement and to

         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 after giving effect to this
         Amendment and Restatement, no Event of Default or Default has occurred
         and is continuing.

                   THE LL&E DEFERRED COMPENSATION ARRANGEMENT
                           FOR SELECTED KEY EMPLOYEES


         WHEREAS, The LL&E Deferred Compensation Arrangement for Selected Key
Employees (the "Plan") was adopted by The Louisiana Land and Exploration Company
(the "Company"); and

         WHEREAS, the Company reserved the right to amend the Plan; and

         WHEREAS, the Benefits Committee appointed by the Chief Executive
Officer of Burlington Resources Inc. is authorized to administer the Plan; and

         WHEREAS, the Benefits Committee is authorized to act on behalf of the
Company in amending the Plan; and

         WHEREAS, no deferrals will be allowed under the Plan with respect to
any period after December 31, 1998; and

         WHEREAS, the Benefits Committee wishes to modify the terms of the
deferral arrangement with respect to participants in the employ of the Company
or any of its affiliates on January 1, 1999 and who did not become eligible to
retire under the Plan prior to January 1, 1999;

         NOW, THEREFORE, the Plan is hereby amended effective as of January 1,
1999 (such amendment to apply to all deferrals under the Plan regardless of the
year of the deferral):

         1.    Section 3.1 is amended by adding the following sentence at the
               end thereof:

               "Anything in this Plan to the contrary notwithstanding, no

         Plan who (i) is in the employ of the Company or any of its affiliates
         January 1, 1999, and (ii) was not eligible for Retirement on December
         31, 1998 (i.e., had not attained age 50 with 10 years of service on
         December 31, 1998) (such a Participant being hereinafter referred to as
         an 'Affected Participant,) shall be determined solely in accordance
         with the provisions set forth below and such Affected Participant and
         his or her Beneficiaries shall have no right to any benefit under this
         Plan except as determined pursuant to the provisions set forth below:

DEFERRED COMPENSATION


                (1)  The balance in the Participant's Compensation Deferral
                     Account ('Account') on December 31, 1998 shall be
                     determined under the provisions of the Plan as in effect
                     prior to January 1, 1999 utilizing the interest rate that
                     would have applied to the applicable deferral in the case
                     of Retirement.

                (2)  With respect to periods on and after January 1, 1999 up to
                     the date of the Participant's termination of employment,
                     the Participant's Account balance determined pursuant to
                     (1) above shall, except as provided below, accrue interest
                     at a rate determined from time to time by the Committee in
                     its sole discretion (the 'Interest Account'). Such interest
                     shall be credited to the Interest Account at the end of
                     each calendar quarter or such other periods as may be
                     determined by the Committee. In lieu of treating the
                     Account as invested in the Interest Account, a Participant
                     may request the Committee (or, with respect to a
                     Participant who is subject to Section 16(b) of the
                     Securities Exchange Act of 1934, as amended, the
                     Compensation and Nominating Committee of the Board of
                     Directors of Burlington Resources Inc.) to credit all or a
                     specified percentage of such Account in phantom or notional
                     shares of common stock of Burlington Resources Inc.
                     hereinafter called `Phantom Stock' (the 'Company Stock
                     Account'), in a notional sub-account credited with units in
                     a Standard & Poor's 500 Composite Stock Price Index fund or
                     in a mutual fund selected by the Committee, in its sole
                     discretion, that tracks such index (the 'S&P Account'), or
                     in any combination of the Interest Account, the Company
                     Stock Account and/or S&P Account; however, the Committee
                     (or Compensation Committee, as the case may be) shall not
                     be obligated to honor any such Participant's request. If
                     the Committee (or Compensation Committee, as the case may
                     be) elects to honor any such request, it shall establish a
                     separate notional sub-account(s) for such Participant under
                     his or her Account, which shall be credited (i) with
                     respect to the Company Stock Accounts, with whole and
                     fractional shares of Phantom Stock as of January 1, 1999
                     (or such other date as the Committee (or the Compensation
                     Committee) designates, and with phantom (notional)
                     dividends with respect to the Phantom Stock, which shall be
                     credited as being reinvested in additional shares of
                     Phantom Stock and (ii) with respect to the S&P Account,
                     with whole and fractional units in the S&P Account as of
                     January 1, 1999 and with any notional distributions on such
                     units, which

DEFERRED COMPENSATION

                     shall be credited as being reinvested in additional units.
                     All credits and debits to the Company Stock Account shall
                     be made based on the Fair Market value per share of the
                     common stock of Burlington Resources Inc. on the applicable
                     date, unless otherwise authorized by the Committee (or the
                     Compensation Committee, as the case may be). For this
                     purpose, 'Fair Market Value' means, as applied to a
                     specific date, the mean between the highest and lowest
                     quoted selling prices at which common stock of Burlington
                     Resources Inc. was sold on such date as reported in the
                     NYSE-Corporate Transactions by The Wall Street Journal on
                     such date or, if no such common stock was traded on such
                     date, on the next preceding date on which such common stock
                     was so traded. If the Committee (or Compensation Committee,
                     as the case may be) chooses to not honor any Participant's
                     request to invest his or her Account in the Company Stock
                     Account or S&P Account, the Participant's Account
                     automatically shall be held in the interest Account. Each
                     Participant who has an Account under the Plan may request
                     that all or a specified percentage of his or her Account
                     balances as of any date be reinvested in the Interest
                     Account, Company Stock Account and/or S&P Account; however,
                     the Committee shall not be obligated to honor any such
                     request. This election shall be in such form as the
                     committee (or Compensation Committee, as the case may be)
                     shall establish and shall comply with all requirements of
                     Section 16(b) of the Securities Exchange Act of 1934, as
                     amended, to the extent applicable. A Participant shall not
                     possess any rights of a stockholder of Burlington Resources
                     Inc. with respect to a share of Phantom Stock.

                (3)  If a Participant had elected Option A with respect to any
                     deferrals to which such option was available, payments will
                     continue to be made in accordance with such Option A
                     election (unless the employment of the Participant
                     terminates prior to the date that payment would otherwise
                     be made, in which event subsection (4) below shall be
                     applicable); provided, however, that such payments pursuant
                     to Option A shall be made only to the extent that the
                     Participant's Account, as determined in accordance with the
                     foregoing provisions of this Article V-A, is sufficient to
                     make such payment. The Participant's Account balance shall
                     be reduced by any amounts so paid out pursuant to Option A.

                (4)  Upon the termination of the Participant's employment for
                     any reason, the Participant's Account balance calculated in

                     accordance with this Article V-A as of such date of
                     termination of employment shall be paid out in a lump sum
                     in cash as soon as administratively practicable following
                     such date of termination of employment, unless the
                     Participant has elected in accordance with election
                     procedures established by the Committee to instead receive
                     distribution in the form of a 5-year or 10-year annuity. If
                     the Participant elects to receive distribution in the form
                     of a 5-year or 10-year annuity, the Participant will
                     receive his or her Account balance in 5 or 10 (as the case
                     may be) equal annual cash installments, with the first
                     installment being paid in January of the calendar year
                     following the calendar year of the Participant's
                     termination of employment and with the succeeding
                     installments being paid in January of each of the 4 or 9
                     (as the case may be) succeeding calendar years. The amount
                     of each such installment shall be determined based on the
                     assumption that his or her Account balance calculated in
                     accordance with the foregoing provisions of this Article
                     V-A as of the date of such termination of employment earns
                     interest after such date on the balance from time to time
                     (taking into account reductions in such balance by reason
                     of distributions) at a fixed rate equal to the average of
                     Moody's Corporate Bond Average rates for the prior 3 years
                     (unless the Committee designates a different rate in its
                     sole discretion) and shall be computed in such manner as to
                     cause (to the maximum extent possible) each such
                     installment to be equal. Such installments shall be paid to
                     the Participant or, in the event of his or her death before
                     receiving all such installments, the remaining installments
                     shall be paid to the Participant's Beneficiary.

Proved reserves represent estimated quantities of oil and gas which geological
and engineering data demonstrate, with reasonable certainty, can be recovered in
future years from known reservoirs under existing economic and operating
conditions. Reservoirs are considered proved if shown to be economically
producible by either actual production or conclusive formation tests.

Proved developed reserves are the portion of proved reserves which can be
expected to be recovered through existing wells with existing equipment and
operating methods.

Proved undeveloped reserves are the portion of proved reserves which can be
expected to be recovered from new wells on undrilled proved acreage, or from
existing wells where a relatively major expenditure is required for completion.

Net acreage and net oil and gas wells are obtained by multiplying gross acreage
and gross oil and gas wells by the Company's working interest percentage in the
properties.

Oil is converted into cubic feet of gas equivalent based on 6 MCF of gas to one
barrel of oil.

TO OUR FELLOW STOCKHOLDERS



                               SHAREHOLDER LETTER

Nineteen ninety-eight was a year which provided us all a vivid reminder of the
extremely cyclical nature of our business as the industry experienced
considerable volatility, uncertainty and turmoil. Although the year began with a
great deal of optimism, an unseasonably mild winter and economic difficulties in
key areas of the world led to extremely low oil prices and disappointing natural
gas prices by year end. In response to this collapse in commodity prices, the
industry's activity level - which began 1998 at record highs - ended the year
near historical lows. This environment is taking its toll on the industry,
causing many companies severe financial distress, forcing the sale of key
assets, necessitating capital spending curtailments and driving industry
consolidation.

Though BR's financial results have been negatively affected by lower commodity
prices, our solid balance sheet, high quality asset base and operational
efficiency have allowed us to remain profitable and focused on our long-term
value creation strategy. We have made prudent adjustments in our capital program
to keep spending levels in line with expected cash flows. However, we have
maintained funding for the programs and projects which we believe are key to our
goal of delivering sustained value growth over a longer time horizon.

Capital expenditures totaled $1.2 billion in 1998 leading to solid operating
results. We replaced 123% of 1998 production at a cost of $1.10 per MCFE.
Reserve additions included the first reserves bookings from our highly
successful Algerian exploration program, as well as substantial additions from
the San Juan Basin of New Mexico. During 1998, we continued the program we began
several years ago investing significant capital in geological and geophysical
activities and lease acquisitions, investments which form the basis for
substantial reserve additions in future years. In fact, over the past three
years, we have dedicated $477 million to this area of our business. We now
expect to begin to reap the benefits of these prior expenditures with a higher
percentage of our 1999 exploration program targeted for the drill bit.

              [Oil and gas platform and other equipment Graphics]

During 1998, our production levels declined 2 percent from the previous year.
While we anticipated the decline in our oil volumes, our gas production for the
year was lower than expected for several reasons: unplanned mechanical
downtime, weather related production interruptions and accelerating decline
rates, primarily in our Gulf of Mexico operations.

Operationally, 1998 was highlighted by a number of successes domestically and
internationally. We achieved a record level of production from our San Juan
operations for the twelfth consecutive year. Development of the Madden Field
in Wyoming moved forward with a successful drilling program in the shallow Lance
and Lower Fort Union Formations, the increase in capacity at the Lost Cabin Gas
Plant and the initiation of production from our third successful Deep Madison
Formation well.

In the Northwest European Shelf, we began development of our East Irish Sea
properties, with plans for first production in the fourth quarter of 1999. We
successfully drilled three new wells in Algeria and participated in the
development of the giant Qoubba Field. We also expanded the Company's presence
in North Africa with our entry into Egypt's Offshore North Sinai Block.

Even after a challenging year like 1998, BR's mission remains unchanged. Our
objective is to deliver long-term shareholder value through value-added growth
and effective cost management. We are committed to maintaining our focus on this
goal, irrspective of near-term production gains or commodity price swings, and
we are resolute in maintaining the financial strength of the Company to pursue
this objective. BR's debt to total capital ratio at year end stood at 39
percent, among the strongest in the E & P sector. With our initial 1999 capital
budget set at $750 million, we believe that we will be able to maintain our
solid financial position during 1999. Such strength will enable us to quickly
react to the opportunities that are sure to be generated in the current
operating environment.

Admittedly, we have adopted an aggressive long-term growth target. In order to
position ourselves for success, we have transformed Burlington Resources from a
purely domestic exploitation company into a global Super Independent. Because of
the maturity of the United States from an exploration perspective, we are
building an international exploration and production business where we believe a
number of meaningful growth opportunities exist.

Our strong domestic asset base provides a dependable source of cash flow,
although there are limited opportunities within this business unit to provide
the type of significant growth we desire. The exception, of course, is the Deep
water play in the Gulf of Mexico to which we have made a major commitment.
Growth initiatives such as our Deep water Gulf of Mexico and international
programs require large capital investments and longer lead times. Our strong
balance sheet and stable domestic production base provide us with key advantages
in pursuing this strategy.

We are enthusiastically looking ahead to our 1999 capital program. In North
America, our Deep water exploration program will become fully operational, with
seven to ten wells planned for the year. In light of the current industry
environment, some of our anticipated 1999 Deep water activity may be delayed due
to a lack of partner participation. We are completing a plant expansion at the
Madden Field, doubling capacity to relieve current production constraints and in
preparation for the next Deep Madison well, which is currently drilling. Our San
Juan Basin conventional gas development will intensify in 1999 with an expanded
Mesaverde infill drilling program. Internationally, in addition to new
exploration and appraisal drilling, we will commence development of the MLN
Field in Algeria once we receive government approval for our exploitation plan.
The Company will drill at least one of the high potential exploration prospects
identified on Venezuela's Delta Centro Block in the first half of the year and
initiate the second phase of our East Irish Sea development by mid-year 1999.

"In pursuing our long-term strategy, we strive to maintain a balance between
near-term production and long-term value growth."


In pursuing our long-term strategy, we strive to maintain a balance between
near-term production and long-term value growth. However, we refuse to fall
prey to the temptation of adding production volumes that do not generate true,
long-term value in order to meet artificially imposed, short-term growth
targets. When we face the inevitable trade-offs in capital allocation, as we
must in today's lower price environment, our choices are driven by what is best
for our shareholders in the long run. Our 1999 capital program reflects this
discipline with our decision to reduce capital spending on the Gulf of Mexico
Shelf where smaller reserve targets and steeper decline rates have made this
area less attractive in relation to other opportunities that can have a
significant impact on the Company's underlying value.

Last year we saw unprecedented deterioration of equity values among E & P
companies and we were certainly not satisfied with the performance of our stock.
Although there is a great deal of pessimism about our industry as we approach
the millennium, at Burlington Resources we are much more optimistic. BR
possesses a high quality domestic asset base that generates considerable cash
flow for reinvestment; a well balanced risk portfolio that includes a large
inventory of exploitation opportunities capable of maintaining stable annual
production without deterioration in overall value; a growing portfolio of high
potential growth oriented exploration projects; and, finally, superior financial
stability and flexibility. These qualities allow us to generate, nurture and
fund high-impact opportunities for the future, even in difficult times.

Reduced industry spending in 1999 will undoubtedly tighten natural gas supply
and create upward pressure on that commodity's price. As one of the largest
holders of U.S. natural gas, we believe our shareholders are superbly positioned
to benefit from the inevitable improvement in this market. And, as one of the
strongest independent E & P companies, both financially and operationally, we
believe our disciplined approach to investment in long-term growth opportunities
will deliver competitive value accretion to our shareholders. On the pages that
follow, we hope to give you insight into our progress, plans for the future and
efforts in positioning ourselves for growth and building long-term shareholder
value.

In closing, this annual report is dedicated to the memory of a friend and former
officer, Hays Warden, retired Senior Vice President and Controller, who recently
lost a battle with cancer. Hays contributed much to BR and will be missed.

BUSINESS AT A GLANCE

Burlington Resources North America (BRNA) was formed as a separate business unit
in 1998 to reinforce the value creation potential of the Company's high quality
domestic assets. With reserves of 7.2 TCFE (81 percent natural gas and 19
percent oil), the size and quality of BRNA's asset base is unparalleled among
independent oil and gas companies. These assets have yielded solid operating
results and a strong production profile since BR's inception and are expected to
be the springboard for the Company's future growth.

BRNA is the largest independent natural gas producer in the U.S. Proved natural
gas reserves at year-end 1998 stood at 5.9 TCF. This reserve base provides an
optimal balance between near-term cash flow generation and long-term stability, 
with a reserve-to-production index of ten years.

"BR North America's primary business objective is to implement a balanced
portfolio of projects which, in aggregate, will contribute to BR's corporate
value growth goals each year."

Technological innovation and cost containment have led to the development of
several core assets in the U.S., where investment repeatability and economies 
of scale have allowed the Company to achieve superior returns. A prime example
is the San Juan Basin, where BR is the largest and lowest cost operator. New
business development activities are focused in areas that may become core 
assets in the future. One example of this strategy is the Deep water Gulf
of Mexico, where the Company has amassed a 185-block leasehold inventory.

BRNA's primary business objective is to implement a balanced portfolio of
projects which, in aggregate, will contribute to BR's corporate value growth
goals. Activities are organized around core asset and strategic focus areas.

Each focus area develops strategies consistent with its unique strengths and
opportunities. Investment options include exploration, exploitation,
developmentand acquisition projects, as well as other business opportunities
designed to enhance the value of core operations. The Company continuously
evaluates its asset portfolio based on investment performance and anticipated
investment potential. This evaluation drives capital allocation and business 
strategies for each asset area.

During 1998, oil and gas capital expenditures related to BRNA's operations
totaled $921 million: $407 million for exploration; $491 million for 
development projects; and $23 million related to proved acquisitions. As
a result of these investments, the business unit added
734 BCFE to its proved oil and gas reserves, achieving a reserve replacement
ratio of 102 percent. Reserve replacement costs averaged $1.25 per MCFE. 
These 1998 results represent continuing strong operating performance in the
U.S. Over the last three years, BR's U.S. reserve replacement has averaged
131 percent, while its reserve replacement costs have averaged $.89 per MCFE.

SAN JUAN BASIN

The San Juan Basin is the cornerstone of BR, providing significant earnings and
the cash flow to fuel the Company's long-term growth strategy. The assets in
this basin account for approximately half of BR's gas reserves and daily gas
production. These assets generate more than three times the cash flow required
to maintain production levels in this basin.

As the largest operator and the lowest cost producer in the basin, BR
continually adds significant value by using its technical expertise to optimize
costs.

The San Juan Basin, located in northwest New Mexico and southwest Colorado, is
one of the most prolific hydrocarbon producing basins in the U.S. The four major
gas producing horizons, the Fruitland Coal, Pictured Cliffs, Mesaverde and
Dakota, in the basin range in depth from 1,000 to 8,500 feet.

In 1998, BR achieved a record level of gas production in the basin for the
twelfth consecutive year. At year end, net daily gas production reached over 840
MMCF per day. Over the last ten years, BR has grown production in the San Juan
Basin at an annual compound rate of over 15 percent. While the rate of growth
has moderated in recent years as the coalbed methane play has matured, the
growth rate over the last five years has averaged seven percent.

Contributing approximately half of BR's net gas production from the San Juan
Basin, the Fruitland Coal is the largest producing coalbed methane reservoir
ever discovered worldwide. Because of BR's development of the Fruitland Coal, it
is the world's largest producer of coalbed methane. BR also operates the Val
Verde Plant, the basin's largest treating plant, along with approximately 420
miles of gathering lines and 14 compressor stations. Optimization projects such
as recavitations and wellsite compression have added net incremental coal seam
gas volumes in each of the last five years, to a peak of over 460 MMCF of gas
per day in early 1998. Net annualized coal seam gas volumes remained relatively
constant at 450 MMCF per day for the year.

In the conventional horizons, a major focus
of the efforts has been the Mesaverde Formation which was originally developed
in the 1950's on 320 acre spacing and down spaced in the early 1970's on 160
acre spacing. In 1994, BR undertook an extensive study of the formation across
the entire basin. Results indicated that down-spaced drilling (infill drilling)
on 80 acre spacing could increase gross recoverable gas reserves by
approximately 1.5 TCF across the basin. A pilot infill drilling program begun in
1997 was expanded in 1998 to include two additional pilot areas. To date, BR has
drilled 38 Mesaverde infill wells, investing about $9 million.

New basin-wide increased density pool rules that allow for 80 acre infilling of
the Mesaverde formation were approved by the New Mexico Oil Conservation
Division in February 1999. BR plans to drill 50 new wells in 1999. By 2000, the
development program is planned to level out at 90 wells per year. The Company
plans to spend about $80 million to drill in excess of 400 infill wells over the
next five years. In total, the Mesaverde infill program exposes the Company to
significant gas reserves at a cost to add of about $.32 per MCF.

Another effort started in 1998 was the Lewis Shale project, involving data
gathering from one of the major source rock shales in the basin. Results are
promising, with the average gross production increase for the first 29
completions at 300 MCF of gas per day and a cost to add of around $.30 per MCF
of gas. The project will continue in 1999 by adding Lewis Shale to existing
Mesaverde well bores with 66 completions planned. If results continue to be
favorable, the Company could expand the program to recomplete over 1,000 wells
in the Lewis Shale over the next five years. Total net costs for the expanded
program would be approximately $145 million, resulting in significant increases
in reserves.

In 1997, BR continued its exploratory efforts in the Deep Pennsylvanian
Formation. Two exploratory wells were drilled that confirmed reservoir quality
rock and hydrocarbon sourcing. During 1998, the Company acquired 350 square
miles of 3-D seismic aimed at locating structural or stratigraphic trapping of
hydrocarbons and delineating prospects for 1999. BR holds 815,000 gross acres in
the Pennsylvanian Formation. While this is a risky opportunity, the target sizes
are large enough that success could result in substantial growth in production.

Early in 1998, BR acquired additional interest in the Allison Unit. The
acquisition substantially increased the Company's ownership in the unit and
added proved reserves of 75 BCFE. It allowed BR to accelerate development
activity in the unit in 1998 and into 1999. The Company will continue to pursue
strategic acquisitions that strengthen its significant position in the basin.


PERMIAN BASIN

BR's position in the Permian Basin comprises in excess of 662,000 net acres in
several significant trends. These properties continue to provide a large number
of opportunities to add both oil and gas reserves. Net production in the basin
was approximately 85 MMCF of gas per day and 12,600 Bbls of oil per day in 1998.

The Company's primary asset in the Permian Basin is the Waddell Ranch, where BR
controls nearly 77,000 gross or 37,000 net acres. Since assuming operations in
1991, BR has continuously increased oil production on the Waddell Ranch
primarily through exploitation and optimization. In 1998, approximately 154
total projects were completed on the Waddell Ranch at a cost of $19 million. In
1999, the Company will implement more than 150 projects to increase recoveries
from existing waterfloods through expansion and optimization.

ANADARKO BASIN

                              [GAS PLANT GRAPHIC]

The Anadarko Basin offers a balanced, diverse inventory of exploitation and
exploration opportunities. During 1998, BR spent $63.5 million in the basin,
completing 55 drilling and workover projects and acquiring 265 square miles of
3-D seismic data surveys. Average net gas production for the year from the basin
was 107 MMCF of gas per day and oil production reached 600 Bbls per day.

A consolidated acreage position of approximately 250,000 net acres, in
conjunction with over 700 square miles of proprietary 3-D seismic data, yields a
significant competitive advantage for growth in the coming years.
In addition, BR's focus on reducing development costs should allow enhanced
economic viability of low-risk exploitation projects in the future.


WILLISTON BASIN

The Williston Basin, located in western North Dakota and northeast Montana, is
one of BR's primary oil producing areas. During 1998, 104 projects were
completed in the basin at a cost of $89 million. At year end, net daily oil
production for the basin was approximately 22,000 Bbls per day.

The Company's activity in 1998 focused on the Cedar Hills and East Lookout Butte
Fields. These fields are located along the Cedar Creek Anticline and are part of
the Red River "B"

"The cornerstone of BR is the San Juan Basin, providing significant earnings 
and the cash flow to fuel the Company's long-term growth strategy."

Trend. During 1998, the Cedar Hills Field delineation was completed in
preparation for unitization and secondary recovery. If unitization of the field
proceeds on schedule, plans for 1999 include constructing waterflood facilities,
infill drilling and converting producing wells into water injectors. Production
response to waterflooding is anticipated in 2001.

In the East Lookout Butte Field, BR is operator of a horizontal waterflood
program. During 1998, BR drilled 24 infill wells and expects to complete infill
drilling by year-end 1999.

With horizontal drilling technology and expertise, BR believes it has a key
technical advantage in the Williston Basin. The Company has drilled over 300
horizontal wells in the basin and over 95 percent of the 1999 drilling budget
for the basin will be spent on approximately 50 horizontal wells. While most E&P
companies use outside directional drilling personnel on their horizontal wells,
BR does all of its directional work with its own wellsite, geoscience and
engineering staff. This has proven to be cost effective and has allowed BR to
develop world class horizontal drilling capabilities, ultimately translating
into higher well productivity and reserve recovery. This technical knowledge
will be even more valuable when applied to other domestic and international
opportunities requiring precision directional drilling skills.


WIND RIVER BASIN

BR's major asset in the Wind River Basin is the Madden Field in central Wyoming,
an asset whose value is being significantly enhanced by applying the Company's
engineering expertise. The field produces natural gas from multiple horizons,
ranging in depth from 5,500 to over 24,000 feet. The Company's working interest
varies by horizon, from 27 to 56 percent. The Madden Deep Unit, operated by BR,
covers 70,000 gross acres. There are currently three well completions in the
prolific deep Madison Formation and 58 producing wells in the shallower
formations.

Increased drilling activity in the shallow horizons in 1998 overcame the natural
field decline and resulted in gross shallow gas production increasing from 72
MMCF of gas per day early in the year to around 92 MMCF of gas per day at year
end. The total year-end field production of 140 MMCF of gas per day is the
highest sustained rate ever recorded in this 30 year old gas field. With
commissioning of additional gas processing capacity in the field, gross field
production is expected to grow to approximately 240 MMCF of gas per day by the
end of 1999.

During 1998, the shallow drilling program was concentrated in the Lower Fort
Union and Lance Formations. These programs were quite successful, with 13 wells
drilled during the year. Completed well costs in Lower Fort Union wells have
been reduced from an average of $1.4 million in late 1997 to under $900 thousand
on the wells drilled in 1998. Additionally, with the average well now being
drilled in 12 to 14 days, drilling time has been cut in half. The 1999 drilling
program includes drilling 20 more Lower Fort Union and shallow Lance wells.


In 1998, BR successfully connected and initiated production from the Bighorn
#4-36, the third well completed in the deeper Madison Formation. Completed in
1997, this well extended the lowest known gas in the pool, increasing proved
gross reserves to approximately 2 TCF of gas.

Unlike the gas produced from the shallow formations, the Madison Formation
contains carbon dioxide and hydrogen sulfide and must be processed prior to
sale. Constructed for this purpose, the Lost Cabin Gas Plant was debottlenecked
during the year, increasing gross inlet capacity from 50 to 65 MMCF of gas per
day. Because production levels continue to be constrained by plant capacity, an
expansion is currently under construction to provide an incremental inlet
capacity of 65 MMCF of gas per day in the third quarter 1999.

BR is currently drilling the fourth Madison well. The Bighorn #5-6 was spud in
January 1999, marking the beginning of the next development phase of the Madison
Formation. This well provides a necessary take point to drain existing proved
reserves. With continued encouraging performance of the existing producing
wells, plans are to drill lower on the structure following the Bighorn #5-6. The
Company believes drilling lower on this structure could possibly double proved
reserves in the formation.

In late 1998, BR reached agreement to participate in the construction of
additional gathering capacity to move gas from central Wyoming toward available
transportation and away from the pipeline constraints. This investment by BR is
key to optimizing the value of its current and future Madden natural gas
reserves.

Cost containment, an aggressive development program and an innovative gas
marketing and transportation plan combine to maximize the value of this world
class asset, which should provide BR with steady cash flow and earnings for the
next two decades or more.


ONSHORE GULF COAST

The Company has a long history of exploration and development in south
Louisiana. Its 600,000 acres of fee lands provide a competitive advantage in an
area where acreage costs are high, leasehold positions are difficult to maintain
and seismic data is expensive to gather. Most of the fee lands are now covered
by 3-D seismic data, a significant factor in the Company's successful drilling
program in 1998. In 1998, BR participated in the drilling of 16 successful
wells, which not only sustained net production but increased it from 134 MMCF of
gas per day and 8,300 Bbls of oil per day in 1997 to 160 MMCF of gas per day and
9,600 Bbls of oil per day in 1998.

An example of BR fee land operations is at Four Isle Dome, located in Terrebonne
Parish, about 25 miles southwest of Houma, Louisiana. The field was first
discovered in 1927 and contains 35 pay sands ranging in depth from 5,700 to
17,500 feet. Since 1997, BR has increased its working interest from 25 percent
to 45 percent and assumed operatorship. This has allowed BR to drill
aggressively, resulting in four successful wells and one recompletion, bringing
the total active well count to seven at year end. Gross daily gas production
increased from under one MMCF of gas per day to over 40 MMCF of gas per day over
this period.

Continued interpretation of a 55 square mile 3-D seismic survey has yielded at
least four additional prospects to be drilled in the Four Isle Dome area in the
next 12 to 18 months. The Company is highly optimistic about these prospects
because 3-D seismic data shows amplitude events that correlate well with
productive reservoirs. Successful results could yield additional volume
increases similar to those achieved in 1998. Other unexploited flanks of the
Four Isle Dome remain to be mapped, which should continue the rejuvenation of
the field.

Another area of onshore activity in 1998 was in the Transition Zone, an area
covering five miles of Louisiana coastline from the Sabine River to Vermilion
Bay. The Company's current acreage position includes 9,400 gross acres,
supported by 3-D seismic data of over 1,000 square miles. The Transition Zone
contains objectives in multiple formations ranging from 13,000 to 21,000 feet.
Although the Transition Zone drilling represents higher risk, potential reserve
targets of 20 to 800 BCF of gas led the Company to participate in a venture with
a 50 percent working interest. Two non-commercial wells have been drilled to
date and a third well was in progress at year end.

During 1998, the Gulf Coast program expanded into south Texas where the Company
participated in drilling 12 successful wells. At Armstrong Ranch in Jim Hogg
County, BR has found new opportunities in another older production area. This
field was

discovered in 1959 using reflection 2-D seismic data, with first production
occurring in the same year. To date, the field has produced in excess of 650
BCF. In 1998, BR successfully drilled two wells in the Wilcox Formation which
were awaiting final completion at year end. When a pipeline is completed, the
two wells are anticipated to produce at a gross combined rate of 20 MMCF of gas
per day. Three additional Wilcox Formation wells are scheduled for drilling in
1999, as well as a lower Wilcox test.

With a total acreage position of over 860,000 acres in south Louisiana and south
Texas and many exploitation opportunities using 3-D seismic data, BR looks
optimistically to its onshore program to help offset the steep decline on its
Gulf of Mexico Shelf, which is consistent with industry experience in this area.


GULF OF MEXICO SHELF

BR's history on the Gulf of Mexico Shelf dates back to the 1970's. The "Shelf"
is defined as water depths less than 600 feet. BR invested $218 million on the
Shelf in 1998, with net gas production averaging about 307 MMCF of gas per day
and net oil production averaging 14,000 Bbls per day for the year. At year end,
the Company had an interest in a total of 236 Shelf leases, many of which are
held by production. In addition to non-operated interests in numerous blocks, BR
operates 60 platforms and 35 fields.

Although the industry's drilling activity on the Shelf has increased
dramatically over the last ten years and many completion technology improvements
have been made, production has remained fairly constant. Smaller reserve
targets, steeper production decline rates and depressed commodity prices led BR
to reassess the economic viability of exploration and exploitation programs on
the Shelf. As a result, BR is reducing its 1999 capital commitment by almost 80
percent, to around $50 million, focusing on low risk exploitation activities.

Such activities include South Timbalier 148, where the Company owns a 40 percent
working interest. It is located 80 miles south of New Orleans, Louisiana, in 110
feet of water. BR's interpretation of 3-D seismic data has resulted in the
drilling of seven successful wells, with net production on the block increasing
from two MMCF of gas per day and 25 Bbls of oil per day in 1994, to a peak of 54
MMCF of gas per day and 2,100 Bbls of oil per day at mid-year 1998. In 1998, BR
participated in the drilling of the B-2 and A-9/A-9ST wells, recompleted the B-1
well, and achieved an annualized production increase of 10 MMCF of gas per day
and 400 Bbls of oil per day. At year end, the net gas production in the field
had declined to 23 MMCF of gas per day and oil production to 660 Bbls per day,
exemplifying the steep production declines being experienced by all participants
on the Shelf. BR's interpretation of additional 3-D seismic data in the
surrounding area prompted the Company to negotiate a farmin of the adjacent
South Timbalier Block 149. At year end, the E-4 exploratory well was drilling
near the projected total depth of 21,776 feet.

High Island A-371, located 115 miles southeast of Galveston, Texas, in 400 feet
of water, is a 100 percent BR-owned field that first
produced in 1996. At its peak in 1996, High Island A-371 produced at a gross
rate of 100 MMCF of gas per day. At year-end 1998, gross production declined to
around 14 MMCF of gas per day. BR has identified six additional drilling
opportunities on the block and will drill several of these prospects in 1999,
which could help turn around the natural production decline of this field.

NORTH AMERICA
PLANS FOR 1999

Drill 50 wells in the Mesaverde 80-acre infill program.

Accomplish 66 Lewis Shale completions in existing Mesaverde well bores.

Drill approximately 50 horizontal wells in the Williston Basin.

Drill the fourth deep Madison well, the Bighorn #5-6, at the Madden Field and
complete the Lost Cabin Gas Plant expansion, bringing the inlet capacity to 130
MMCF of gas per day.

Drill 7 to 10 wells in the Gulf of Mexico Deep water program, including BR's
first operated prospect, Spoon, at Ewing Bank Block 913.

GULF OF MEXICO DEEP WATER

Hydrocarbon basins in the U.S. have continued to mature, making economically
attractive exploration opportunities increasingly rare. The Deep water Gulf of
Mexico represents one of the last world class exploration opportunities in the
U.S. The Company believes that the Deep water provides an excellent opportunity
for value-added growth in North America. A significant part of BR's future
growth strategy revolves around its
Deep water commitment.

The Company's exploratory Deep water acreage is diverse, covering water depths
from 600 to 8,000 feet, but is focused on several geologic trends. The acreage
position offers a balance of near-term and long-term drilling opportunities,
while also having the scale to provide for repeatable investments. BR has
identified approximately 75 leads or prospects on the basis of 2-D and 3-D
seismic data. At year end, BR had 185 blocks in its inventory, making it one of
the largest leaseholders in the Deep water.

In December 1998, production came on stream at Green Canyon Block 89, the
Cinnamon prospect, from the A-1 Well. Three additional wells are planned for
the first phase of development on this block in which BR owns a 17 percent
interest.

Although BR's Deep water program is not scheduled to be fully underway until
1999, the Company participated in the drilling of three wells in 1998, none of
which found commercial quantities of hydrocarbons. In preparation for its fully
operational Deep water drilling program, BR contracted for the construction of a
semisubmersible drilling rig capable of operating in water depths up to 7,500
feet. The rig will be delivered in the third quarter of 2000 and will be
exclusively available to BR for up to six years.

BR's Deep water drilling program is scheduled to accelerate in 1999, with seven
to ten wells planned. In light of the current industry environment, some of our
anticipated 1999 Deep water activity may be delayed due to a lack of partner
participation. In total, the 1999 program should expose the Company to
significant reserve potential. The first well to be drilled in the 1999 program
is the BR-operated Spoon prospect, located in Ewing Bank Block 913 in
approximately 800 feet of water. In addition, joint ventures have been forged
between BR and other companies to share risk and to gain exposure to other
exploration opportunities. One such venture will begin drilling in 1999. In the
fourth quarter of 1999, the joint venture will take delivery of a drillship
capable of drilling in up to 10,000 feet of water. The rig will be available to
the joint venture for up to five years.

BR will continue to pursue opportunities in the Deep water in 2000 and beyond.
The Company projects that its typical program in the future will consist of
drilling up to ten new wells per year. Based on its success from an aggressive
exploration program, BR plans to commit the capital to fund its drilling
program, as well as the capital necessary for future development.

BUSINESS AT A GLANCE

BR entered the international oil and gas business through two major events: its
merger with LL&E, which had an established international presence, and the
acquisition of approximately 700 BCF of undeveloped proved and probable gas
reserves in the East Irish Sea. In 1998, BR affirmed its commitment to a global
presence as a key element of its long-term growth strategy by forming Burlington
Resources International (BRI).

BRI's proved reserves at year-end 1998 totaled 801 BCFE, approximately 35
percent oil and 65 percent natural gas. The proved reserves are concentrated in
the Northwest European Shelf, in the Irish Sea and the United Kingdom and Dutch
sectors of the North Sea. BRI also has proven reserves in Algeria, Colombia and 
Indonesia. Although it is a relatively small part of BR's total business today, 
BRI is positioning itself to provide significant future growth to BR through 
high potential exploration and development opportunities.

"BRI has adopted a strategy with three major elements: focus, balance and 
discipline."

In building its portfolio, BRI adopted a strategy based on focus, balance and
discipline. Focus translates into a decision to concentrate in a limited number
of geographical areas. Each area must be capable of becoming material to BR and
offer potential for repeatable or continued investment opportunities to provide
sustainable growth. Balance refers to building a portfolio which includes
acquisition, exploitation and exploration opportunities, as well as creating a
mix of short, medium and longer term projects that can provide a sustainable and
growing production profile. Finally, although a sense of urgency is crucial to
grow the international business and contribute to corporate growth goals, BR
takes a disciplined approach when considering new projects and ventures. This
approach assures that opportunities create value and are beneficial to the
corporate portfolio.

An objective assessment was undertaken in 1998 of hydrocarbon basins around the
world based on geotechnical, commercial and geopolitical risks balanced with
BR's knowledge and competencies. As a result, five areas were selected for
business development activities: the Northwest European Shelf; North Africa;
Northern South America; the Far East; and West Africa. Strategies for the first
four are centered around expanding the Company's existing assets in these areas,
while an entry strategy has been developed for West Africa, where the Company
currently has no operations.

Oil and gas capital expenditures devoted to international activities totaled
$136 million in 1998: $102 million for exploration; $30 million for development
activities; and $4 million related to proved acquisition activities. Proved
reserves added during the year totaled 225 BCFE. International projects are
typically viewed on a multi-year investment cycle. As a start-up operation,
single year statistics are somewhat distorted. Nonetheless, BR's international
reserve replacement averaged 260 percent over the three-year period 1996 to
1998, and reserve replacement costs over the same period averaged $.82 per MCFE.

NORTHWEST EUROPEAN SHELF

BR's Northwest European Shelf focus area includes the U.K., Dutch and Danish
sectors of the North Sea, as well as the East Irish Sea. Current production
comes from the U.K. and Dutch sectors of the North Sea, where in 1998 the
Company's average net production was 66 MMCF of gas per day and 11 MBbls of oil
per day.

In the U.K. North Sea, production is from the T-Block Complex, where BR has an
11 percent working interest, and from the Brae Complex, where the Company has a
six percent working interest. Although base production is declining in both
fields, this is being mitigated by new exploration and development opportunities
within each area. In 1999, newly identified leads at Brae will be evaluated for
drilling. Also, one well is scheduled for drilling at the T-Block Thelma Field
to extend field limits.

The Company participates in natural gas exploration and production in the Dutch
and Danish sectors of the North Sea. Net production in this area averaged 30
MMCF of gas per day in 1998. In 1999, three wells are scheduled to be drilled in
the Dutch North Sea. In the Danish North Sea, BR participated in a new license
which was awarded for exploration on the Ribe and Viborg Blocks. During 1999,
seismic evaluation of leads on these blocks will be conducted, with exploratory
drilling expected in 2000. Work commitment under the license requires
acquisition of 170 square miles of seismic data and drilling of three wells. The
Company has assessed the reserve potential of this area to be significant.

In mid-1998, BR acquired a 20 percent working interest in central North Sea
Blocks 21/12 and 21/13 through two farmins. In August 1998, an exploratory
discovery was made when the 21/12-3 well encountered a 100-foot thick oil
producing Jurassic sandstone formation. BR has a 26 percent interest in this
well as a result of a farmin. The well, located 80 miles off the coast of
Scotland in 279 feet of water, tested at a stabilized rate of 8,200 Bbls of oil
per day. Development options are currently being evaluated.

BR's most exciting project on the Northwest European Shelf is in the East Irish
Sea. In late 1997, BR acquired ten licenses in the East Irish Sea, encompassing
267,000 acres at a cost of $143 million, including a 90 percent working interest
in seven operated, undeveloped gas fields with estimated gross recoverable
reserves in excess of 700 BCF.

The properties are located 25 miles offshore in approximately 100 feet of water
and are covered by high quality 3-D seismic surveys. BR originally included
construction of processing and transportation facilities into the project timing
and economic evaluation. Development plans were accelerated and economics were
enhanced when an agreement was reached with a nearby operator to transport and
process the gas from two sweet gas fields, Dalton and Millom. The Company also
received development and operatorship approval for Dalton Annex B from the U.K.
government.

The first development well for these fields was spud in February 1999, with a
total of three wells scheduled for the year. Subsea completion of these wells
will initiate first production in October 1999, with gross production reaching
95 MMCF of gas per day by year end. Additional drilling, completion and
facilities work is scheduled in 2000. Gross production from the project is
expected to reach 170 MMCF of gas per day. Development options for the five
remaining sour gas fields are being evaluated.

NORTH AFRICA

The Company's operations on Algeria's Block 405, located in the Berkine Basin of
eastern Algeria, are the centerpiece of the Company's North African focus area.
Industry activity in this highly prospective area has discovered in excess of
three billion Bbls of recoverable oil reserves since the country opened to
foreign investment in 1989.

BR was a relatively early entrant into Algeria, having initiated a production
sharing agreement in 1993 that gave the Company a 65 percent working interest,
before participation by Sonatrach, the state-owned oil company, in two
exploration blocks in the Saharan Berkine Basin, Blocks 215 and 405.

As operator, BR has drilled 12 wells on Block 405 so far and all have
encountered hydrocarbons. Appraisal of these accumulations is ongoing. However,
the Company now believes it has discovered at least three commercial oil fields,
the MLN Field, the MLSE Field and the MLNE Field which is an extension of the
giant Qoubba Field, discovered on adjacent blocks. A fourth discovery well, the
MLC-1, is currently under evaluation. The Company is also appraising deeper
accumulations encountered in at least three wells. The nature and full extent of
this deeper reservoir is not yet known.

Proved reserves for Block 405 were booked in 1998 with the potential to increase
significantly with successful delineation of recent discoveries. In compliance
with its production sharing agreement, the Company relinquished a portion of
Block 405 in 1998 as it entered the second five-year exploration phase of the
contract. The area relinquished included a portion of the unexplored area of the
block, as well as the MLE gas discovery, which was the first well drilled on the
block. BR also relinquished Block 215 in 1998.

Capital and exploration expenditures in Algeria totaled $45 million in 1998. Of
this total, $33 million was devoted to exploratory, development and appraisal
drilling, $11 million was related to seismic evaluation and $1 million was
committed to production facility construction.

Two wells were drilled in the central portion of Block 405 in 1998. In August,
BR began drilling the MLW-1, a wildcat well 8.4 miles southwest of MLN-4, which
had encountered the presence of a deeper Devonian reservoir in addition to the
Triassic TAG. The MLW-1 encountered hydrocarbons at both intervals. While the
TAG Formation failed to produce fluids to the surface, the Devonian flowed 1,545
Bbls of oil per day and 3 MMCF of gas per day, confirming the presence of a
productive Devonian reservoir in the western portion of the block.

Following the completion of the MLW-1, the rig was moved to drill the MLN-5, 6.8
miles northeast of the MLW-1 and 1.6 miles southwest of the MLN-4. The well
tested at a rate of 6,820 Bbls per day of 44 degree API gravity oil and 7 MMCF
of gas per day from the Devonian Formation, but was not productive in the TAG
reservoir. Two other thin hydrocarbon zones identified were not tested and will
be evaluated in future drilling. The presence of the Devonian at MLN-4, MLN-5
and MLW-1 is highly encouraging and could indicate a very productive and
widespread accumulation on Block 405. Additional drilling in 1999 should provide
additional data in determining the extent and potential of the reservoir. At
year end, the Company was planning development for the MLN Field. The plan will
be submitted to the government in 1999 and, with timely approval by Sonatrach,
production at the field is anticipated in late 2001.

In June of 1998, BR announced the discovery of a new field, MLSE, with the
successful drilling of the MLSE-1. Located in the southeastern portion of the
block, the well encountered four hydrocarbon bearing intervals. The well flowed
at a combined rate of 14,638 Bbls of oil per day and 107 MMCF of gas per day. In
the fourth quarter, the MLSE-2 was drilled, establishing the limits of the two
main producing horizons and was suspended as a potential water injector. In late
1998, additional 3-D seismic survey work was initiated to cover the southeast
portion of the block. When this survey is completed in 1999, additional drilling
will more fully appraise the extent of the MLSE Field.

The MLNE Field, representing approximately six percent of the giant Qoubba
Field, which extends onto the block from the north, is currently under
development. Production is anticipated in 2002.

BR will drill six more wells on Block 405 in 1999. A total capital commitment of
$84 million has been earmarked for drilling, facilities development and
completion of seismic survey work.

BR's approach to exploration includes allocating a small part of its portfolio
to frontier exploration opportunities. These are high-risk opportunities in
relatively unexplored regions that provide tremendous upside potential if a
discovery is made. In 1998, BR took a 20 percent interest in a frontier
exploration project of this type in Eritrea. The concession covers nine million
gross acres and carries a commitment to drill at least three wells. The first
well was drilled in 1998 and although the well was unsuccessful, the fact that
free oil was encountered in sidewall cores was very encouraging. The second well
on the concession was also unsuccessful. The third well was spud in January
1999. Although a high-risk venture, any success in Eritrea could be significant
because of the huge acreage position covered by the concession.

In December 1998, BR announced an agreement to earn a working interest in both
exploration and development opportunities at the Offshore North Sinai Block,
located in the Nile River Delta area of the Mediterranean Sea. The agreement
provides the Company with a 50 percent working interest in an 870,000 gross acre
block that contains three proved undeveloped Pliocene gas fields, several
additional exploration prospects which are similar in nature to these Pliocene
accumulations and an exploration prospect in deeper Miocene stratigraphy. In
exchange, BR has agreed to fund a disproportionate share of future capital
commitment to develop these proved undeveloped gas reserves. Initial development
is projected to begin during 1999, with production to commence during 2001.
Additionally, if the high potential deeper Miocene prospect, referred to as Seti
East, is successful and deemed to be commercial, BR has agreed to fund a
disproportionate share of future development costs associated with the project,
as well. Total capital committed to this project in 1999 is $22 million.


NORTHERN SOUTH AMERICA

BR's efforts in Latin America are focused in northern South America. Presently,
the Company has a 14 percent interest in the Casanare Association Contract in
Colombia as well as exploration interests in Venezuela, Colombia and Peru.

The Latin American strategy provides the springboard to quickly transform the
business from a highly leveraged exploration portfolio to one of balance -
providing production, exploitation and exploration opportunities. BR intends to
aggregate substantive interest in key producing assets then work to enhance the
value through exploitation. Success of the strategy hinges on maintaining focus,
aggressive pursuit of key assets and value-based acquisitions.

                                 PLANS FOR 1999


Submit plan of development for the Algerian MLN Field in Block 405.

Drill 6 additional wells in Algeria on Block 405 and participate in 12
development wells in the Qoubba Field.

Begin development of the Dalton and Millom fields in the East Irish Sea, with
initial gross production of 95 MMCF of gas per day commencing in the fourth
quarter of 1999.

Commence exploratory drilling on the Delta Centro Block in Venezuela.

Pursue aggressively opportunities to establish a West African focus area and
expand the Far East focus area.

Of the exploration interests, the most significant is the Delta Centro Block in
eastern Venezuela. BR operates this block with a 35 percent working interest.
Located in the Orinoco River Basin near the prolific Oficina Trend the 525,000
gross acre block is covered by 230 square miles of 3-D seismic and 230 miles of
2-D seismic data. As part of its work commitment, the Company will drill three
exploratory wells before the end of 2001, with an option to extend the
exploratory period for an additional four years. The most promising prospect,
Wakajara, is scheduled for drilling in 1999. During 1998, extensive
environmental evaluation was performed in preparation for drilling.

In Colombia, BR has a 14 percent non-operated working interest in 12 fields in
the Casanare Association Contract Area. During 1998, three development wells
were drilled in this area, mitigating natural production declines in these
mature fields. The Company also holds a 25 percent working interest in a 288,000
gross acre association contract located in the San Jacinto Association Contract
Area. The contract is located in the upper Magdalena Valley Basin. During 1998,
93 miles of 2-D seismic data were acquired. A decision on the initial
exploratory well is expected by mid-year 1999.

Peru Block 32 is non-operated with BR holding a 35 percent interest. Results of
the 1998 acquisition and processing of approximately 450 kilometers of 2-D
seismic have resulted in the identification of the Guineayacu prospect. Site
preparation for drilling of this exploratory well should commence by year-end
1999, with drilling anticipated in early 2000.


FAR EAST

BR holds a 15 percent working interest in the Indonesian KAKAP block, located in
the West Natuna Sea. The partners in KAKAP recently negotiated a 22 year
agreement for the sale of up to 325 MMCF of gas per day to Singapore. This
long-term sales agreement enhances the value of KAKAP reserves and production,
which historically have had limited marketability.

BR has selected the Far East as a potential focus area for value-added growth.
The Far East growth strategy targets selected basins in Indonesia, Thailand,
Malaysia, Vietnam, China, Bangladesh and Australia, primarily by acquisition.


WEST AFRICA

The fifth focus area selected by BR is West Africa, unique in being the only
focus area that has not been established around an existing acreage position.
This region was selected on the basis of its world class reserves, tremendous
upside potential, relative stability, and very active deal flow. During 1998,
the West Africa team was established, conducted initial studies of the region,
and pursued several attractive exploration and production opportunities. BR is
committed to establishing a strategic foothold within the West Africa region
that will lead to a significant value-added position in this prolific
hydrocarbon province.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS


FINANCIAL CONDITION AND LIQUIDITY

       The Company's long-term debt to capital ratio at December 31, 1998 and
1997 was 39 percent and 37 percent, respectively.

       The Company's credit facilities are comprised of a $600 million revolving
credit agreement that expires in February 2003 and a $400 million revolving
credit agreement that expires in February 2000. The $400 million revolving
credit agreement is renewable annually by mutual consent. As of December 31,
1998, there were no borrowings outstanding under the credit facilities. At
December 31, 1998, the Company had outstanding commercial paper borrowings of
$190 million at an average interest rate of 6 percent. The Company also has the
capacity to issue $1 billion of securities under a shelf registration statement
filed with the Securities and Exchange Commission.

       The Company has a total of $640 million of debt to be repaid in 1999. Of
this amount, $450 million represents fixed-rate debt which the Company intends
to refinance with other fixed-rate long-term debt in 1999. The remaining $190
million represents commercial paper.

       In July 1998, the Company's Board of Directors approved the repurchase of
up to two million shares of its Common Stock. During 1998, the Company
repurchased 435,000 shares of its Common Stock for $15 million. Since December
1988, the Company has repurchased approximately 32 million shares. In
conjunction with the Company's stock repurchase program, the Company sold put
options ("options") during 1998. The options entitled the holders, upon exercise
on the expiration dates, to sell shares of BR Common Stock to the Company at
specified prices. Alternatively, the Company retained the ability to settle the
options in cash. During 1998, the Company sold 400,000 options with an average
strike price of $37.25 per share and received an average premium of $2.67 per
option. During 1998, 110,000 options were exercised, 25,000 expired and 265,000
remained outstanding at December 31, 1998 with expiration dates through March of
1999.

       Net cash provided by operating activities for 1998 was $770 million
compared to $1,122 million and $995 million in 1997 and 1996, respectively. The
decrease in 1998 compared to 1997 was primarily due to lower operating income
and working capital changes. The increase in 1997 compared to 1996 was primarily
due to significantly higher operating income and working capital changes.

       In June 1997, the Company completed its divestiture program of
non-strategic assets which was announced in July 1996. As planned, the Company
sold approximately 27,000 wells and related facilities. Before closing
adjustments, gross proceeds for 1997 from the sales of oil and gas properties
related to this divestiture program were approximately $450 million.

       On July 31, 1996, the Company completed the sale of its crude oil
refinery and terminal, including crude oil and refined product inventories, for
approximately $70 million. The net book value of refinery property, plant and
equipment and inventory at that date was approximately $68 million.

       The Company and its subsidiaries are named defendants in numerous
lawsuits and named parties in numerous governmental and other proceedings
arising in the ordinary course of business. While the outcome of lawsuits and
other proceedings cannot be predicted with certainty, management believes these
matters will not have a material adverse effect on the consolidated financial
position of the Company, although results of operations and cash flows could be
significantly impacted in the reporting periods in which such matters are
resolved.

       The Company has certain other commitments and uncertainties related to
its normal operations. Management believes that there are no other commitments,
uncertainties or contingent liabilities that will have a material adverse effect
on the consolidated financial position, results of operations or cash flows of
the Company.

CAPITAL EXPENDITURES AND RESOURCES

       Capital expenditures during 1998 totaled $1,165 million compared to
$1,245 million and $804 million in 1997 and 1996, respectively. The Company
invested $1,030 million on internal development and exploration during 1998
compared to $941 million and $646 million in 1997 and 1996, respectively. The
Company invested $27 million for proved property acquisitions in 1998 compared
to $214 million and $92 million in 1997 and 1996, respectively.

       Capital expenditures for 1999, excluding proved property acquisitions,
are projected to be approximately $750 million. Capital expenditures are
expected to be primarily for internal development and exploration of oil and gas
properties and plant and pipeline expenditures. Capital expenditures will be
funded from internal cash flows, supplemented, if needed, by external financing.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS


MARKETING

Domestic

       In pursuit of its mission to build long-term shareholder value, the
Company's marketing strategy is to maximize the value of its production by
developing marketing flexibility from the wellhead to its ultimate sale. The
Company's gas production is gathered, processed, exchanged and transported
utilizing various firm and interruptible contracts and routes to access the
highest value market hubs. The Company's customers include local distribution
companies, electric utilities and a diverse portfolio of industrial users. The
Company maintains the capacity to ensure its production can be marketed either
at the wellhead or downstream at market sensitive prices.

       All of the Company's crude oil production is sold to third parties at the
wellhead or transported to market hubs where it is sold or exchanged. NGLs are
typically transported to market hubs, primarily in the Houston area, and sold to
third parties.

International

       The Company's international oil and gas is produced from non-operated
properties. These products are sold to third parties either directly by the
Company or by the operators of the properties.

Commodity Pricing and Demand

       Substantially all of the Company's crude oil and natural gas production
is sold on the spot market or under short-term contracts at market sensitive
prices. Spot market prices for domestic crude oil and natural gas are subject to
volatile trading patterns in the commodity futures markets, including among
others, the New York Mercantile Exchange ("NYMEX"). Crude oil prices are also
affected by quality differentials, by worldwide political developments and by
the actions of the Organization of Petroleum Exporting Countries.

       There is also a difference between the NYMEX futures contract price for a
particular month and the actual cash price received for that month in a U.S.
producing basin or at a U.S market hub, which is referred to as the "basis
differential."

       In the ordinary course and conduct of its business, the Company utilizes
futures contracts traded on the NYMEX and the Kansas City Board of Trade, and
over-the-counter price and basis swaps and options with major crude oil and
natural gas merchants and financial institutions to hedge its price risk
exposure related to the Company's U.S. production. The gains and losses realized
as a result of these derivative transactions are substantially offset in the
cash market when the hedged commodity is delivered. In order to accommodate the
needs of its customers, the Company also uses price swaps to convert gas sold
under fixed price contracts to market prices.

       The Company uses a sensitivity analysis technique to evaluate the
hypothetical effect that changes in the market value of crude oil and natural
gas may have on the fair value of the Company's derivative instruments. At
December 31, 1998, the potential decrease in fair value of commodity derivative
instruments assuming a 10 percent adverse movement in the underlying commodities
would result in an 89 percent decrease in the net deferred amount.

       For purposes of calculating the hypothetical change in fair value, the
relevant variables are the type of commodity (crude oil or natural gas), the
commodity futures prices, the volatility of commodity prices and the basis and
quality differentials. The hypothetical change in fair value is calculated by
multiplying the difference between the hypothetical price (adjusted for any
basis or quality differentials) and the contractual price by the contractual
volumes.

DIVIDENDS

       On January 13, 1999, the Board of Directors declared a common stock
quarterly cash dividend of $.1375 per share, payable April 1, 1999 to
shareholders of record on March 12, 1999. Dividend levels are determined by the
Board of Directors based on profitability, capital expenditures, financing and
other factors. The Company declared cash dividends on Common Stock totaling
approximately $98 million during 1998.

                                                                              23

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

RESULTS OF OPERATIONS

Year Ended December 31, 1998 Compared With Year Ended December 31, 1997

       The Company reported net income of $86 million or $.48 basic earnings per
common share in 1998 compared to $319 million or $1.80 basic earnings per common
share in 1997. The 1997 results included a $.40 per share charge related to the
1997 merger with The Louisiana Land and Exploration Company ("LL&E") for
severance and related exit costs and transaction costs. The 1997 results also
included an $.18 per share gain related to the sales of oil and gas properties.

       Revenues were $1,637 million in 1998 compared to $2,000 million in 1997.
Average oil prices decreased 31 percent to $13.28 per barrel in 1998 and average
gas prices decreased 10 percent to $1.97 per MCF which decreased revenues $180
million and $129 million, respectively. Oil sales volumes decreased 5 percent in
1998 to 82.7 MBbls per day and gas sales volumes decreased 1 percent to 1,647
MMCF per day which decreased revenues $31 million and $18 million, respectively.
Oil and gas sales volumes decreased primarily due to natural production declines
in certain areas, adverse weather conditions and third-party plant outages.

       Costs and Expenses were $1,419 million in 1998 compared to $1,497 million
in 1997. Costs and expenses in 1997 included an $80 million charge related to
the 1997 merger with LL&E for severance and related exit costs and transaction
costs. Excluding the $80 million charge in 1997, costs and expenses in 1998
increased $2 million compared to 1997. The increase was primarily due to a $39
million increase in exploration costs and a $4 million increase in production
and processing expenses. These increases were partially offset by a $19 million
decrease in production taxes, a $15 million decrease in administrative expenses
and a $7 million decrease in depreciation, depletion and amortization expenses.
Administrative expenses decreased primarily due to a reduction in employees.

       Interest Expense was $148 million in 1998 compared to $142 million in
1997. The increase was primarily due to higher outstanding commercial paper
balances during 1998.

       Other Income-Net was $25 million in 1998 compared to $50 million in 1997.
The decrease in other income is primarily related to lower gains on sales of oil
and gas properties.

       The effective income tax rate was an expense of 9 percent in 1998
compared to an expense of 23 percent in 1997. The decreased tax expense in 1998
versus 1997 was primarily a result of lower pretax income partially offset by
lower benefits from nonconventional fuel tax credits.

Year Ended December 31, 1997 Compared With Year Ended December 31, 1996

       The Company reported net income of $319 million or $1.80 basic earnings
per common share in 1997 compared to net income of $335 million or $1.89 basic
earnings per common share in 1996. The 1997 results included a $.40 per share
charge related to the merger with LL&E for severance and related exit costs and
transaction costs. The 1997 results also included an $.18 per share gain related
to the sales of oil and gas properties. The 1996 results included an $.11 per
share charge related to the divestiture program and reorganization for severance
and other related exit costs.

       Revenues were $2,000 million in 1997 compared to $2,200 million in 1996.
Revenues decreased $264 million as a result of the sale of the refinery on July
31, 1996. Average oil prices decreased 6 percent to $19.24 per barrel and oil
sales volumes decreased 4 percent to 87.2 MBbls per day which decreased revenues
$37 million and $31 million, respectively. These decreases were partially offset
by an average gas price increase of 6 percent to $2.18 per MCF and an increase
in gas sales volumes of 4 percent to 1,669 MMCF per day which increased revenues
$82 million and $46 million, respectively. Gas volumes increased due to
continued development of gas properties. Oil volumes were down primarily due to
the divestiture program.

       Costs and Expenses were $1,497 million in 1997 compared to $1,620 million
in 1996. Costs and expenses in 1997 included an $80 million charge related to
the merger with LL&E for severance and related exit costs and transaction costs.
Costs and expenses in 1996 included $30 million related to the divestiture
program and reorganization. Excluding the $80 million charge in 1997 and the $30
million charge in 1996, costs and expenses in 1997 decreased $173 million from
1996. The decrease was primarily due to a $254 million decrease in refinery
costs resulting from the sale of the refinery and a $27 million decrease in
production and processing expenses. These decreases were partially offset by a
$100 million increase in exploration costs, a $5 million increase in
depreciation, depletion and amortization and a $4 million increase in production
taxes.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS


       Interest Expense was $142 million in 1997 compared to $147 million in
1996. The decrease was primarily due to lower outstanding commercial paper
balances during 1997.

       Other Income -- Net was $50 million in 1997 due to a gain related to the
sales of oil and gas properties associated with the Company's 1996 divestiture
program.

OTHER MATTERS

Year 2000 Compliance

       The Company began a program during 1996 to assess computer software and
hardware (hereafter referred to as information technology) for year 2000
compliance. The Company determined that because significant portions of
information technology were scheduled for replacement before the year 2000 that
its exposure with respect to information technology was not material.

       The Company's year 2000 project plan involves four phases; assessment,
remediation, testing, and implementation. The Company has completed its
assessment of all material systems that could be affected by the year 2000
issue. The assessment confirmed that information technology exposures were not
material, however, assets used in producing, gathering and transporting
hydrocarbons (hereafter referred to as operating equipment) are at risk.

       For its operating equipment, the Company has completed 85 percent of the
remediation phase for all operationally significant equipment and expects to
complete testing and implementation in the second quarter of 1999.

       The total cost of the year 2000 project is being funded through operating
cash flows and is estimated at $3 million of which $2 million has been incurred.

       The Company has contacted all third-party vendors and suppliers of
products and services that it considers critical to its operations in order to
ascertain their level of year 2000 readiness. The Company has no means of
ensuring that all customers and suppliers will be year 2000 compliant. The
inability of these parties to complete their year 2000 resolution process could
materially impact the Company. As a result, the Company will consider new
business relationships with alternate providers of products and services as
necessary and to the extent alternatives are available.

       The Company's plan to complete the year 2000 modifications is based on
management's best estimates, which were derived utilizing numerous assumptions
of future events including the continued availability of certain resources and
other factors. However, there can be no guarantee that these estimates will be
achieved and actual results could differ materially from those plans. Specific
factors that might cause such material differences include, but are not limited
to, the availability and cost of personnel trained in this area, the ability to
locate and correct all relevant computer codes and similar uncertainties.

       The Company's goal is to ensure that all critical systems and processes
under its direct control remain operational. However, because certain systems
and processes may be linked with systems outside of the Company's control, there
can be no assurance that all implementations will be successful. As a result,
the Company is developing a contingency plan, which will be complete at the end
of the first quarter 1999, to respond to any failures that may occur. The cost
estimates associated with the contingency plan are currently being developed.
Management does not expect the costs of the Company's year 2000 project to have
a material adverse effect on the Company's financial position or results of
operations. Presently, based on information available, the Company cannot
conclude that any failure of the Company or third parties to achieve year 2000
compliance will not adversely effect the Company.

Recent Accounting Pronouncements

       In June 1998, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards ("SFAS") No. 133, Accounting for Derivative
Instruments and Hedging Activities, which is effective for fiscal years
beginning after June 15, 1999.

       SFAS No. 133 establishes accounting and reporting standards for
derivative instruments, including certain derivative instruments embedded in
other contracts, and for hedging activities. It also requires that an entity
recognize all derivatives as either assets or liabilities in the balance sheet
and measure those items at fair value. If certain conditions are met, a
derivative may be specifically designated as (a) a hedge of the exposure to
changes in the fair value of a recognized asset or liability or an unrecognized
firm commitment, (b) a hedge of the exposure to variable cash flows of a
forecasted transaction or (c) a hedge of the foreign currency exposure of a net
investment in a foreign operation, an unrecognized firm commitment, an
available-for-sale security, or a foreign-currency-denominated forecasted
transaction. The Company plans to adopt SFAS No. 133 during the first quarter of
the year ended December 31, 2000 and is currently evaluating the effects of this
pronouncement.

                                                                              25

BURLINGTON RESOURCES INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.       ACCOUNTING POLICIES


PRINCIPLES OF CONSOLIDATION AND REPORTING

         The consolidated financial statements include the accounts of
Burlington Resources Inc. ("BR") and its majority-owned subsidiaries (the
"Company"). All significant intercompany transactions have been eliminated in
consolidation. Due to the nature of financial reporting, management makes
estimates and assumptions in preparing the consolidated financial statements.
Actual results could differ from estimates. The consolidated financial
statements include certain reclassifications that were made to conform to
current presentation. Such reclassifications have no impact on net income or
stockholders' equity.


CASH AND CASH EQUIVALENTS

         All short-term investments purchased with a maturity of three months or
less are considered cash equivalents. Cash equivalents are stated at cost, which
approximates market value.


SHORT-TERM INVESTMENTS

         Short-term investments consist of highly-liquid debt securities with a
maturity of more than three months. The securities are available for sale and
are carried at fair value based on quoted market prices. As of December 31,
1997, the fair value of these investments approximated amortized cost.
Unrealized gains and losses, net of tax, are included as a component of
stockholders' equity until realized. Realized gains and losses are based on
specific identification of the securities sold.


INVENTORIES

         Inventories of materials, supplies and products are valued at the lower
of average cost or market.


PROPERTIES

         Oil and gas properties are accounted for using the successful efforts
method. Under this method, all development costs and acquisition costs of proved
properties are capitalized and amortized on a units-of-production basis over the
remaining life of proved developed reserves and proved reserves, respectively.
Costs of drilling exploratory wells are initially capitalized, but charged to
expense if and when a well is determined to be unsuccessful. In addition,
unamortized capital costs at a field level are reduced to fair value if the sum
of expected undiscounted future cash flows is less than net book value.

         Costs of retired, sold or abandoned properties that constitute a part
of an amortization base are charged or credited, net of proceeds, to accumulated
depreciation, depletion and amortization. Gains or losses from the disposal of
other properties are recognized currently. Expenditures for maintenance, repairs
and minor renewals necessary to maintain properties in operating condition are
expensed as incurred. Major replacements and renewals are capitalized. Estimated
dismantlement and abandonment costs for oil and gas properties are accrued, net
of salvage value, based on a units-of-production method.


REVENUE RECOGNITION

         Gas revenues are recorded on the entitlement method. Under the
entitlement method, revenue is recorded based on the Company's net interest.


FUNCTIONAL CURRENCY

         International exploration and production operations are considered an
extension of the Company's operations. The assets, liabilities and operations of
international locations are therefore measured using the United States dollar as
the functional currency. Foreign currency transaction adjustments, which are not
material, are included in net income.


HEDGING AND RELATED ACTIVITIES

         In order to mitigate the risk of market price fluctuations, the Company
utilizes options and swaps to hedge future crude oil and natural gas production.
Changes in the market value of these contracts are deferred until the gain or
loss is recognized on the hedged commodity. To qualify as a hedge, these
transactions must be designated as a hedge and changes in their fair value must
correlate with changes in the price of anticipated future production such that
the Company's exposure to the effects of commodity price changes is reduced. The
Company also enters into swap agreements to convert fixed price gas sales
contracts to market-sensitive contracts. Gains or losses resulting from these
transactions are included in revenue as the related physical production is
delivered.

         These instruments are measured for effectiveness on an enterprise basis
both at the inception of the contract and on an ongoing basis. If these
instruments are terminated prior to maturity, resulting gains or losses continue
to be deferred until the hedged item is recognized in income.

<PAGE>   35
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


         Treasury lock agreements are used to hedge interest rate exposure on
specific anticipated debt issuances of the Company. Accordingly, the
differential paid or received by the Company on maturity of a treasury lock
agreement is recognized as an adjustment to interest expense over the term of
the underlying financing transaction.


CREDIT AND MARKET RISKS

         The Company manages and controls market and counterparty credit risk
through established formal internal control procedures which are reviewed on an
ongoing basis. The Company attempts to minimize credit risk exposure to
counterparties through formal credit policies, monitoring procedures and through
establishment of valuation reserves related to counterparty credit risk. In the
normal course of business, collateral is not required for financial instruments
with credit risk.


INCOME TAXES

         Income taxes are provided based on earnings reported for tax return
purposes in addition to a provision for deferred income taxes. Deferred income
taxes are provided to reflect the tax consequences in future years of
differences between the financial statement and tax basis of assets and
liabilities. Tax credits are accounted for under the flow-through method, which
reduces the provision for income taxes in the year the tax credits are earned. A
valuation allowance is established to reduce deferred tax assets if it is more
likely than not that the related tax benefits will not be realized.


STOCK-BASED COMPENSATION

         The Company uses the intrinsic value based method of accounting for
stock-based compensation. Under this method, the Company records no compensation
expense for stock options granted when the exercise price for options granted is
equal to the fair market value of the Company's stock on the date of the grant.


EARNINGS PER COMMON SHARE

         Basic earnings per common share ("EPS") is computed by dividing income
available to common stockholders by the weighted-average number of common shares
outstanding for the period. The weighted average number of common shares
outstanding for computing basic EPS was 177 million for the years ended December
31, 1998, 1997 and 1996. Diluted EPS reflects the potential dilution that could
occur if securities or other contracts to issue common stock were exercised or
converted into common stock. The weighted average number of common shares
outstanding for computing diluted EPS, including dilutive stock options, was 178
million for the years ended December 31, 1998, 1997 and 1996. For the years
ended December 31, 1998, 1997 and 1996, approximately 4 million, 600 thousand
and 3 million shares, respectively, attributable to the exercise of outstanding
options were excluded from the calculation of diluted EPS because the effect was
antidilutive. No adjustments were made to reported net income in the computation
of EPS.

2.       MERGER

         On July 17, 1997, BR and The Louisiana Land and Exploration Company
("LL&E")announced that they had entered into an Agreement and Plan of Merger
(the "Merger"). On October 22, 1997, the Merger was completed and LL&E became a
wholly-owned subsidiary of the Company. Pursuant to the Merger, BR issued
52,795,635 shares of its Common Stock based on an exchange ratio of 1.525 for
each outstanding share of LL&E stock. The Merger was accounted for as a pooling
of interests and qualified as a tax-free reorganization. The transaction was
valued at approximately $3 billion based on BR's closing stock price on October
22, 1997. During the fourth quarter of 1997, the Company recorded a pretax
charge of $80 million ($71 million after tax) for direct costs associated with
the Merger. These costs primarily consist of $44 million for severance and
related exit costs and $36 million for direct transaction costs. Approximately
$2 million of accrued unpaid costs remained on the consolidated balance sheet as
of December 31, 1998.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


         The above net deferred tax liabilities, as of December 31, 1998 and
1997, include deferred state income tax liabilities of approximately $39 million
for both years.

         The Alternative Minimum Tax ("AMT") credit carryforward, related
primarily to nonconventional fuel tax credits, is available to offset future
federal income tax liabilities. The AMT credit carryforward has no expiration.
The benefit of these tax credits is recognized in net income for accounting
purposes and is reflected in the current tax provision to the extent the Company
is able to utilize the credits for tax return purposes.

         The foreign tax credit carryforward is available through the year 2003
to offset future federal income taxes. The federal income tax net operating loss
carryforward is available through the year 2009 to offset future federal taxable
income, subject to the separate return limitation provisions of the federal
income tax regulations.

         A valuation allowance is provided for uncertainties surrounding the
realization of certain foreign tax credit carryforwards and certain deferred
foreign tax credits.

4. COMMODITY HEDGING ACTIVITIES

Gas Swaps

         The Company enters into gas swap agreements to fix the price of
anticipated future natural gas production. As of December 31, 1998, the Company
has the following volumes hedged.

</TABLE>


Gas Basis Swaps

         The Company enters into gas basis swap agreements to fix a component of
the sales price of anticipated future natural gas production. This component is
expressed as the differential between a location and Henry Hub. These
transactions are accounted for as hedges of the Company's underlying production.
As of December 31, 1998, the Company had 40 million MMBTU of 1999 natural gas
production hedged at a fixed differential of approximately $.28 per MMBTU. The
deferred loss on these transactions as of December 31, 1998 is approximately $2
million.

Options Contracts

         The Company enters into put option agreements to set a floor price on
anticipated future natural gas production while allowing the Company to
participate in market price increases that exceed those floor prices. These
transactions are accounted for as hedges of the Company's underlying production.
As of December 31, 1998, the Company has 34 million MMBTU of 1999 natural gas
production hedged at a floor price of $1.80 per MMBTU. The deferred gain on
these transactions as of December 31, 1998 is approximately $1 million.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


         The Company had fixed-rate debt maturities of $450 million, $150
million, $150 million, $100 million, $0 and $1,090 million due in 1999, 2000,
2001, 2002, 2003 and thereafter, respectively. The Company's commercial paper
borrowings at December 31, 1998 had an average interest rate of 6 percent.

         The Company's credit facilities are comprised of a $600 million
revolving credit agreement that expires in February 2003 and a $400 million
revolving credit agreement that expires in February 2000. The $400 million
revolving credit agreement is renewable annually by mutual consent. Annual fees
are .08 and .12 percent, respectively, of the $600 million and $400 million
commitments. At the Company's option, interest on borrowings is based on the
Prime rate or Eurodollar rates. The unused commitment under these agreements is
available to cover debt due within one year; therefore, commercial paper and
fixed-rate debt due within one year are classified as long-term debt. Under the
covenants of these agreements, debt cannot exceed 60 percent of capitalization
(as defined in the agreements). As of December 31, 1998, there were no
borrowings outstanding under these credit facilities. In addition, the Company
has the capacity to issue $1 billion of securities under shelf registration
statements filed with the Securities and Exchange Commission.

         The Company utilizes a treasury lock agreement to hedge the effect of
interest rate movements on anticipated debt transactions. At December 31, 1998,
the aggregate notional amount of the lock agreement was $128 million. At
December 31, 1998, the fair value of the agreement was an obligation of $11
million. The treasury lock agreement matures in the first quarter 1999.

6.       TRANSPORTATION ARRANGEMENTS WITH EL PASO NATURAL GAS COMPANY

         In 1998, 1997 and 1996, approximately 37 percent, 41 percent and 43
percent, respectively, of the Company's gas production was transported to direct
sale customers through El Paso Natural Gas Company's ("EPNG") pipeline systems.
These transportation arrangements are pursuant to EPNG's approved Federal Energy
Regulatory Commission tariffs applicable to all shippers. The Company expects to
continue to transport a substantial portion of its future gas production through
EPNG's pipeline system. See Note 9 for demand charges paid to EPNG which provide
the Company with firm and interruptible transportation capacity rights on
interstate and intrastate pipeline systems.

7. CAPITAL STOCK

STOCK OPTIONS

         The Company's 1993 Stock Incentive Plan (the "1993 Plan") succeeds its
1988 Stock Option Plan which expired by its terms in May 1993 but remains in
effect for options granted prior to May 1993. The 1993 Plan provides for the
grant of stock options, restricted stock, stock purchase rights and stock
appreciation rights or limited stock appreciation rights (together "SARs").

         Under the 1993 Plan, options may be granted to officers and key
employees at fair market value on the date of grant, exercisable in whole or
part by the optionee after completion of at least one year of continuous
employment from the grant date and have a term of ten years. At December 31,
1998, 6,049,276 shares were available for grant under the 1993 Plan.

         In 1997, the Company adopted the 1997 Employee Stock Incentive Plan
(the "1997 Plan") from which stock options and restricted stock ("Awards") may
be granted to employees who are not eligible to participate in the 1993 Plan.
The options are granted at fair market value on the grant date, become
exercisable in whole or part by the optionee after completion of at least one
year of continuous employment and have a term of ten years. The 1997 Plan limits
Awards, in aggregate, to a maximum of one million shares annually.

         The weighted average fair values of options granted during the years
1998, 1997 and 1996 were $11.32, $10.45 and $12.45, respectively. The fair
values of employee stock options were calculated using a variation of the
Black-Scholes stock option valuation model with the following weighted average
assumptions for grants in 1998, 1997 and 1996: stock price volatility of 24.18
percent, 18.35 percent and 18.62 percent, respectively; risk free rate of return
ranging from 4.66 percent to 6.00 percent; dividend yield of 1.36 percent, 1.07
percent and 1 percent, respectively; and an expected term of 5 years. If the
fair value based method of accounting had been applied, the Company's net income
and EPS would have been reduced to the pro forma amounts indicated below. The
fair value of stock options included in the pro forma amounts is not necessarily
indicative of future effects on net income and EPS.

STOCK APPRECIATION RIGHTS

         The Company has granted SARs in connection with certain outstanding
options under the 1988 Stock Option Plan. SARs are subject to the same terms and
conditions as the related options. A SAR entitles an option holder, in lieu of
exercise of an option, to receive a cash payment equal to the difference between
the option price and the fair market value of the Company's Common Stock based
upon the plan provisions. To the extent the SAR is exercised, the related option
is cancelled and to the extent the option is exercised, the related SAR is
cancelled. The outstanding SARs are exercisable only under certain circumstances
related to significant changes in the ownership of the Company or its holdings,
or certain changes in the constitution of its Board of Directors. At December
31, 1998, there were 74,276 SARs outstanding related to stock options with a
weighted average exercise price of $34.21 per share.


PREFERRED STOCK AND PREFERRED STOCK PURCHASE RIGHTS

         The Company is authorized to issue 75,000,000 shares of preferred
stock, par value $.01 per share, and as of December 31, 1998, there were no
shares issued. On December 9, 1998, the Company's Board of Directors designated
3,250,000 of the authorized preferred shares as Series A Junior Participating
Preferred Stock. Upon issuance, each one-hundredth of a share of Series A Junior
Participating Preferred Stock will have dividend and voting rights approximately
equal to those of one share of Common Stock of the Company. In addition, on
December 9, 1998, the Board of Directors declared a dividend distribution of one
Right for each outstanding share of Common Stock of the Company to shareholders
of record on December 16, 1998. The Rights become exercisable if, without the
Company's prior consent, a person or group acquires securities having 15 percent
or more of the voting power of all of the Company's voting securities (an
"Acquiring Person") or ten days following the announcement of a tender offer
which would result in such ownership. Each Right, when exercisable, entitles the
registered holder to purchase from the Company one-hundredth of a share of
Series A Junior Participating Preferred Stock at a price of $200 per one
hundredth of a share, subject to adjustment. If, after the Rights become
exercisable, the Company were to be involved in a merger or other business
combination in which its Common Stock was exchanged or changed or 50% or more of
the Company's assets or earning power were sold, each Right would permit the
holder to purchase, for the exercise price, stock of the acquiring company
having a value of twice the exercise price. In addition, except for certain
permitted offers, if any person or group becomes an Acquiring Person, each Right
would permit the purchase, for the exercise price, of Common Stock of the
Company having a value of twice the exercise price. Rights owned by an Acquiring
Person are void. The Rights may be redeemed by the Company under certain
circumstances until their expiration date for $.01 per Right.

8.   RETIREMENT BENEFITS

     The Company's pension plans are non-contributory defined benefit plans
covering substantially all employees. The benefits are based on years of
credited service and final average compensation. Contributions to the plans are
limited to amounts that are currently deductible for tax purposes. Contributions
are intended to provide not only for benefits attributed to service to date but
also for those expected to be earned in the future.

     The Company has postretirement medical and dental care plans for a closed
group of retirees and their dependents and certain employees. The postretirement
benefit plans are unfunded and the Company funds claims on a cash basis. The
Company also maintains a Medicare Part B reimbursement plan and life insurance
coverage for a closed group of retirees.

The following tables set forth the amounts recognized in the Consolidated
Balance Sheet and Statement of Income.

     During 1998, the Company recognized a settlement expense of approximately
$800 thousand related to the employee reduction associated with the LL&E merger
in the fourth quarter of 1997.

     A 5 percent annual rate of increase in the per capita cost of covered
health care benefits was assumed for 1998. The rate is assumed to decrease
gradually to 4 percent for 2003 and remain at that level thereafter.

     Assumed health care cost trends have a significant effect on the amounts
reported for the postretirement medical and dental care plans. A one-percentage
point change in assumed health care cost trend rates would have the following

DRILLING RIG COMMITMENTS

     During 1998, the Company entered into agreements to lease or participate in
the use of various drilling rigs. The exposure with respect to these commitments
ranges from $152 million to $280 million depending on partner participation.
These agreements extend through the year 2004.

LEGAL PROCEEDINGS

     The Company is involved in several proceedings challenging the payment of
royalties for its crude oil and natural gas production.

     On November 20, 1997, the Company and numerous other defendants entered
into a settlement agreement in a lawsuit styled as The McMahon Foundation, et
al. v. Amerada Hess Corporation, et al. This lawsuit is a proposed class action
consisting of both working interest owners and royalty owners against numerous
defendants, all of which are oil companies and/or purchasers of oil from oil
companies, including Burlington Resources Oil & Gas Company, formerly known as
Meridian Oil Inc. ("BROG") and LL&E. The plaintiffs allege that the defendants
conspired to fix, depress, stabilize and maintain at artificially low levels the
prices paid for oil by, among other things, setting their posted prices at
arbitrary levels below competitive market prices. Cases involving similar
allegations have been filed in federal courts in other states. On January 14,
1998, the United States Judicial Panel on Multidistrict Litigation issued an
order consolidating these cases and transferring the McMahon case to the United
States District Court for the Southern District of Texas in Corpus Christi. The
Company and other defendants have entered into a Settlement Agreement which
received preliminary approval by the Court on October 28, 1998. The Court has
set a hearing to finally determine the fairness, accuracy and reasonableness of
the Settlement Agreement beginning in April 1999.

     The Company is also involved in several governmental proceedings relating
to the payment of royalties. Various administrative proceedings are pending
before the Minerals Management Service ("MMS") of the United States Department
of the Interior with respect to the proper valuation of oil and gas produced on
federal and Indian lands for purposes of paying royalties on production sold by
BROG to its affiliate, Burlington Resources Trading Inc. ("BRTI"), or gathered
by its affiliate, Burlington Resources Gathering Inc. In general, these
proceedings stem from regular MMS audits of the Company's royalty payments over
various periods of time and involve the interpretation of the relevant federal
regulations. Most of these administrative proceedings currently have been
suspended pending


                                                                              39
<PAGE>   44
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

LEGAL PROCEEDINGS (CONTINUED)

negotiations between the Company and the MMS to resolve their disputes regarding
the appropriate valuation methodology or pending resolution of the federal False
Claims Act litigation as hereinafter described.

     In late February 1998, the Company and numerous other oil and gas companies
received a complaint filed in the United States District Court for the Eastern
District of Texas in Lufkin in a lawsuit styled as United States of America ex
rel J. Benjamin Johnson, Jr., et al v. Shell Oil Company, et al. alleging
violations of the civil False Claims Act. The United States has intervened in
this lawsuit as to some of the defendants, including the Company, and has filed
a separate complaint. This suit alleges that the Company underpaid royalties for
crude oil produced on federal and Indian lands through the use of below-market
posted prices in the sale of oil from BROG to BRTI. The suit alleges that
royalties paid by BROG based on these posted prices were lower than the
royalties allegedly required to be paid under federal regulations, and that the
forms filed by BROG with the MMS reporting the royalties paid were false,
thereby violating the civil False Claims Act. The Company and others have also
received document subpoenas and other inquiries from the Department of Justice
relating to the payment of royalties to the federal government for natural gas
production. These requests and inquiries have been made in the context of one or
more other False Claims Act cases brought by individuals which remain under seal
and are now being investigated by the Civil Division of the Department of
Justice. The Company has responded and continues to respond to these requests
and inquiries, but the Company does not know what action, if any, the Department
of Justice will take with regard to these other cases. If the government chooses
not to intervene and pursue these cases, the individuals who initially brought
these cases are free to pursue them in return for a share, if any, of any final
settlement or judgment. In addition, the Company has been advised that it is a
target of a criminal investigation by the United States Attorney for the
District of Wyoming into the alleged underpayment of oil and gas royalties. The
Company has responded to numerous grand jury document subpoenas in connection
with an investigation and is otherwise cooperating with the investigation.
Management cannot predict when the investigation will be completed or its
ultimate outcome.

     Based on the Company's present understanding of the various governmental
proceedings relating to royalty payments, described in the preceding two
paragraphs, the Company believes that it has substantial defenses to these
claims and intends to vigorously assert such defenses. However, in the event
that the Company is found to have violated the civil False Claims Act or is
indicted or convicted on criminal charges, the Company could be subjected to a
variety of sanctions, including treble damages, substantial monetary fines,
civil and/or criminal penalties and a temporary suspension from entering into
future federal mineral leases and other federal contracts for a defined period
of time. While the ultimate outcome and impact on the Company cannot be
predicted with certainty, management believes that the resolution of these
proceedings will not have a material adverse effect on the consolidated
financial position of the Company, although results of operations and cash flows
could be significantly impacted in the reporting periods in which such matters
are resolved.

     In addition to the foregoing, the Company and its subsidiaries are named
defendants in numerous other lawsuits and named parties in numerous governmental
and other proceedings arising in the ordinary course of business. While the
outcome of these other lawsuits and proceedings cannot be predicted with
certainty, management believes these matters, other than the above-described
proceedings, will not have a material adverse effect on the consolidated
financial position, results of operations or cash flows of the Company.

10. DIVESTITURE PROGRAM AND REORGANIZATION

     In June 1997, the Company completed its divestiture program of
non-strategic assets which was announced in July 1996. As planned, the Company
sold approximately 27,000 wells and related facilities. Before closing
adjustments, gross proceeds for 1997 from the sales of oil and gas properties
related to this divestiture program were approximately $450 million. During
1997, the Company recorded a pretax gain of approximately $50 million related to
the sales of oil and gas properties. This program allowed the Company to
reorganize and resulted in a reduction of 456 employees. As of December 31,
1997, this program was complete.

     On July 31, 1996, the Company completed the sale of its crude oil refinery
and terminal, including crude oil and refined product inventories, for
approximately $70 million. The net book value of refinery property, plant and
equipment and inventory at that date was approximately $68 million.

11. DEFERRED REVENUE

     In September 1996, the Company received cash proceeds of $108 million for a
transaction in which it is obligated to deliver gas through December 31, 2002.
The proceeds were recorded as deferred revenue and are being amortized into
revenues as the gas is delivered. Approximately $18 million, $20 million and $13
million of deferred revenue was recognized in 1998, 1997 and 1996, respectively.

12. RECENT ACCOUNTING PRONOUNCEMENTS

     In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards ("SFAS") No. 133, Accounting for Derivative
Instruments and Hedging Activities, which is effective for fiscal years
beginning after June 15, 1999.

     SFAS No. 133 establishes accounting and reporting standards for derivative
instruments, including certain derivative instruments embedded in other
contracts, and for hedging activities. It also requires that an entity recognize
all derivatives as either assets or liabilities on the balance sheet and measure
those items at fair value. If certain conditions are met, a derivative may be
specifically designated as (a) a hedge of the exposure to changes in the fair
value of a recognized asset or liability or an unrecognized firm commitment, (b)
a hedge of the exposure to variable cash flows of a forecasted transaction or
(c) a hedge of the foreign currency exposure of a net investment in a foreign
operation, an unrecognized firm commitment, an available-for-sale security, or a
foreign-currency-denominated forecasted transaction. The Company plans to adopt
SFAS No. 133 during the first quarter of the year ended December 31, 2000 and is
currently evaluating the effects of this pronouncement.

REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders of Burlington Resources Inc.


     In our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of income, cash flows and stockholders' equity present
fairly, in all material respects, the financial position of Burlington Resources
Inc. and its subsidiaries at December 31, 1998 and 1997, and the results of
their operations and their cash flows for each of the three years in the period
ended December 31, 1998, in conformity with generally accepted accounting
principles. These financial statements are the responsibility of the Company's
management; our responsibility is to express an opinion on these financial
statements based on our audits. We conducted our audits of these statements in
accordance with generally accepted auditing standards which require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for the opinion expressed
above.

SUPPLEMENTARY FINANCIAL INFORMATION


     The following table reflects estimated quantities of proved oil and gas
reserves. These reserves have been reduced for royalty interests owned by
others. These reserves have been estimated by the Company's petroleum engineers.
The Company considers such estimates to be reasonable, however, due to inherent
uncertainties, estimates of underground reserves are imprecise and subject to
change over time as additional information becomes available.

FORWARD-LOOKING STATEMENTS


The Company may, in discussions of its future plans, objectives and expected
performance in periodic reports filed by the Company with the Securities and
Exchange Commission (or documents incorporated by reference therein) and in
written and oral presentations made by the Company, include projections or other
forward-looking statements within the meaning of Section 27A of the Securities
Act of 1933 or Section 21E of the Securities Exchange Act of 1934, as amended.
Such projections and forward-looking statements are based on assumptions which
the Company believes are reasonable, but are by their nature inherently
uncertain. In all cases, there can be no assurance that such assumptions will
prove correct or that projected events will occur, and actual results could
differ materially from those projected.
