     SUMMARY

     Murphy Oil Corporation is a worldwide oil and gas exploration and
     production company with refining and marketing operations in the United
     States and the United Kingdom as well as pipeline and crude oil trading
     operations in Canada.  As used in this report, the terms Murphy, Murphy
     Oil, we, our, its and Company may refer to Murphy Oil Corporation or any
     one or more of its consolidated subsidiaries.

     The Company was originally incorporated in Louisiana in 1950 as Murphy
     Corporation; reincorporated in Delaware in 1964, at which time it adopted
     the name Murphy Oil Corporation; and reorganized in 1983 to operate solely
     as a holding company of its various businesses.  Its activities are
     classified into two business segments:  (1) "Exploration and Production,"
     and (2) "Refining, Marketing and Transportation."  Additionally,
     "Corporate" activities include interest income, interest expense and
     overhead not allocated to either of the business segments.  On December 31,
     1996, Murphy completed a spin-off to its stockholders of its wholly owned
     farm, timber and real estate subsidiary, Deltic Farm & Timber Co., Inc.
     (reincorporated as "Deltic Timber Corporation").

     The information appearing in the 1997 Annual Report to Security Holders
     (1997 Annual Report) is incorporated in this Annual Report on Form 10-K as
     Exhibit 13 and is deemed to be filed as part of this 10-K report as
     indicated under Items 1, 2, 5, 6, 7, 8 and 14.  A narrative of the
     graphic and image information that appears in the paper format version of
     Exhibit 13 is included in the electronic Form 10-K document as an appendix
     (pages Ex. 13A-1 through Ex. 13A-8) to Exhibit 13.

     In addition to the following information about each business segment, data
     relative to Murphy's operations, properties and industry segments,
     including revenues by class of products and financial information by
     geographic area, are described on pages 1, 30 through 38, 45, 52, 53, 56
     and 57 of the 1997 Annual Report, which is filed in this 10-K report 
     as Exhibit 13.

     EXPLORATION AND PRODUCTION

     During 1997, Murphy's principal exploration and/or production activities
     were conducted in the United States and Ecuador by wholly owned Murphy
     Exploration & Production Company (Murphy Expro) and its subsidiaries, in
     western Canada and offshore eastern Canada by wholly owned Murphy Oil
     Company Ltd. (MOCL) and its subsidiaries and in the U.K. North Sea and the
     Atlantic Margin by wholly owned Murphy Petroleum Limited.  Murphy's crude
     oil and natural gas liquids production in 1997 was in the United States,
     Canada, the U.K. North Sea and Ecuador; its natural gas was produced and
     sold in the United States, Canada and the U.K. North Sea.  MOCL also has a
     five-percent interest in Syncrude Canada Ltd., which extracts synthetic
     crude oil from oil sand deposits in northern Alberta.  In addition,
     subsidiaries of Murphy Expro conducted exploration activities in various
     other areas including China, the Faroe Islands, Ireland, the Falkland
     Islands, Venezuela, Bangladesh, Brazil, Pakistan, Denmark and the Caspian
     Sea.

     Murphy's estimated net quantities of proved oil and gas reserves and proved
     developed oil and gas reserves at December 31, 1994, 1995, 1996 and 1997 by
     geographic area are reported on page 55 of the 1997 Annual Report, which is
     filed in this 10-K report as Exhibit 13.  Murphy has not filed and is not
     required to file any estimates of its total proved net oil or gas reserves
     on a recurring basis with any federal or foreign governmental regulatory
     authority or agency other than the U.S. Securities and Exchange Commission.
     Annually, Murphy reports gross reserves of properties operated in the
     United States to the U.S. Department of Energy; such reserves are derived
     from the same data from which estimated net proved reserves of such
     properties are determined.

     Net crude oil, condensate, and gas liquids production and net natural gas
     sales by geographic area with weighted average sales prices for each year
     in the five-year period ended December 31, 1997 are shown on page 59 of the
     1997 Annual Report, which is filed in this 10-K report as Exhibit 13.

     EXPLORATION AND PRODUCTION (Contd.)

     Production costs for the last three years in U.S. dollars per equivalent
     barrel produced, including natural gas volumes converted to equivalent
     barrels of crude oil on the basis of approximate relative energy content (6
     MCF = 1 bbl.), are discussed on page 33 of the 1997 Annual Report, which is
     filed in this 10-K report as Exhibit 13.

     Supplemental disclosures about oil and gas producing activities are
     reported on pages 54 through 58 of the 1997 Annual Report, which is filed
     in this 10-K report as Exhibit 13.

     At December 31, 1997, Murphy held leases, concessions, contracts or permits
     on nonproducing and producing acreage as shown by geographic area in the
     following table.  Gross acres are those in which all or part of the working
     interest is owned by Murphy; net acres are the portions of the gross acres
     applicable to Murphy's working interest.  All amounts shown are in
     thousands of acres.

     Murphy distributes refined products from 57 terminal locations in the
     United States to retail and wholesale accounts in the United States (by
     MOUSA) and in Canada (by a MOCL subsidiary) under the brand names SPUR(R)
     and Murphy USA(R) and to unbranded wholesale accounts.  Ten terminals are
     wholly owned and operated by MOUSA, 16 are jointly owned and operated by
     others and the remaining 31 are owned by others.  Of the terminals wholly
     owned or jointly owned, four are marine terminals, two are supplied by
     truck, two are adjacent to MOUSA's refineries and 18 are supplied by
     pipeline.  MOUSA receives products at the terminals owned by others in
     exchange for deliveries from the Company's wholly owned and jointly owned
     terminals.  At the end of 1997, refined products were marketed at wholesale
     and/or retail through 585 branded stations in 17 southeastern and upper-
     midwestern states and six branded stations in the Thunder Bay area of
     Ontario, Canada.

     At the end of 1997, Murco distributed refined products in the United
     Kingdom from the Milford Haven refinery; three wholly owned, rail-fed
     terminals; seven terminals owned by others where products are received in
     exchange for deliveries from the Company's wholly owned terminals; and 396
     branded stations under the brand names MURCO and EP.

     Murphy owns a 20-percent interest in a 120-mile, 165,000-barrel-a-day
     refined products pipeline that transports products from the Meraux refinery
     to two common carrier pipelines serving Murphy's marketing area in the
     southeastern United States.  The Company also owns a 22-percent interest in
     a 312-mile crude oil pipeline in Montana and Wyoming with a capacity of
     120,000 barrels a day and a 3.2-percent interest in LOOP Inc., which
     provides deepwater off-loading accommodations off the Louisiana coast for
     oil tankers and onshore facilities for storage of crude oil.  In addition,
     Murphy owns 29.4 percent of a 22-mile, 300,000-barrel-a-day crude oil
     pipeline between LOOP storage at Clovelly, Louisiana and Alliance,
     Louisiana and 100 percent of a 24-mile, 200,000-barrel-a-day crude oil
     pipeline from Alliance to the Meraux refinery.  The pipeline from Alliance
     to Meraux is also connected to another company's pipeline system, allowing
     crude oil transported by that system to be shipped to the Meraux refinery.

     Additional information about current refining, marketing and transportation
     activities and a statistical summary of key operating and financial
     indicators for each year in the five-year period ended December 31, 1997
     are reported on pages 2, 3, 5 through 7, 20 through 27 and 60 of the 1997
     Annual Report, which is filed in this 10-K report as Exhibit 13.

     EMPLOYEES

     Murphy had 1,338 full-time employees at December 31, 1997.

     COMPETITION AND OTHER CONDITIONS WHICH MAY AFFECT BUSINESS

     Murphy operates in the oil industry and experiences intense competition
     from other oil and gas companies, many of which have substantially greater
     resources.  In addition, the oil industry as a whole competes with other
     industries in supplying energy requirements around the world.  Murphy is a
     net purchaser of crude oil and other refinery feedstocks and occasionally
     purchases refined products and may therefore be required to respond to
     operating and pricing policies of others, including producing country
     governments from whom it makes purchases.  Additional information
     concerning current conditions of the Company's business is reported under
     the caption "Outlook" on page 37 of the 1997 Annual Report, which is filed
     in this 10-K report as Exhibit 13.

     The operations and earnings of Murphy have been and continue to be affected
     by worldwide political developments.  Many governments, including those 
     that are members of the Organization of Petroleum Exporting Countries
     (OPEC), unilaterally intervene at times in the orderly market of crude oil
     and natural gas produced in their countries through such actions as fixing
     prices and determining rates of production and who may sell and buy the
     production.  In addition, prices and availability of crude oil, natural gas
     and refined products could be influenced by political unrest and by various
     governmental policies to restrict or increase petroleum usage and supply.
     Other governmental actions that could affect Murphy's operations and
     earnings include tax changes and regulations concerning: currency
     fluctuations, protection and/or remediation of the environment (See the
     caption "Environmental" on page 36 of the 1997 Annual Report, which is
     filed in this 10-K report as Exhibit 13.), preferential and discriminatory
     awarding of oil and gas leases, restraints and controls on imports and
     exports, safety, and relationships between employers and employees.  
     Because these and other government-influenced factors too numerous to list
     are subject to constant changes dictated by political considerations and
     are often made in great haste in response to changing internal and
     worldwide economic conditions and to actions of other governments or
     specific events, it is not practical to attempt to predict the effects of
     such factors on Murphy's future operations and earnings.

     Murphy's policy is to insure against known risks when insurance is
     available at costs and terms Murphy considers reasonable.  Certain existing
     risks are insured by Murphy only through Oil Insurance Limited, which is
     operated as a mutual insurance company by certain participating oil
     companies including Murphy and was organized to insure against risks for
     which commercial insurance is unavailable or for which the cost of
     commercial insurance is prohibitive.

each stockholder of record entitled to vote thereat by delivering a notice
thereof to him personally, or by mailing such notice in a postage prepaid

request that notices intended for him be directed to another address, in which
case such notice shall be directed to him at the address designated in such
request.  Notice of any meeting of stockholders shall not be required to be
given to any stockholder who shall attend such meeting in person or by proxy;
and if any stockholder shall in person or by attorney thereunto authorized, in
writing or by telegraph, cable, radio or wireless and confirmed in writing,

otherwise required by the laws of the State of Delaware or the certificate of
incorporation.  The vote thereat on any question need not be by ballot unless
required by the laws of the State of Delaware.

qualify, or until his death, resignation or removal.

stockholders for the election of directors and on the same day the board of
directors shall meet for the purpose of organization, the election of officers
and the transaction of other business.  Notice of such meeting need not be

specified in a notice given as hereinafter provided for special meetings of the
board of directors or in a consent and waiver of notice thereof signed by all
the directors.

     Section 6.  Regular Meetings.  Regular meetings of the board of directors
may be held at such time and place, within or without the State of Delaware, as
shall from time to time be determined by the board of directors.  After there

member of the board of directors, regular meetings may be held without further
notice being given.

directors shall be held whenever called by the Chairman of the Board or by a
majority of the directors.  Notice of each such meeting shall be mailed to each
director, addressed to him at his residence or usual place of business, at least

him at such place by telegraph, cable, radio or wireless, or be delivered
personally or by telephone, not later than the day before the day on which such
meeting is to be held.  Each such notice shall state the time and place of the
meeting but need not state the purposes thereof.  Notice of any meeting of the
board of directors need not be given to any director, however, if waived by him
in writing or by telegraph, cable, radio or wireless and confirmed in writing,
whether before or after such meeting, or if he shall be present at such meeting.

notice thereof having been given if all the directors then in office shall be
present thereat.

     Section 8.  Resignation.  Any director of the Company may resign at any
time by giving written notice to the Chairman of the Board or the Secretary of
the Company.  The resignation of any director shall take effect upon receipt of

unless otherwise specified therein, the acceptance of such resignation shall not
be necessary to make it effective.

or without cause, by the affirmative vote of the holders of record of a majority
of the issued and outstanding class of stock of the Company entitled to vote for
the election of such director, given at a special meeting of the stockholders
called for that purpose.  The vacancy in the board of directors caused by any
such removal may be filled by the stockholders at such meeting.

     Section 10.  Vacancies.  Any vacancy that shall occur in the board of
directors by reason of death, resignation, disqualification or removal or any
other cause whatever, unless filled as provided in Section 9 hereof, shall be
filled by the majority (even if that be only a single director) of the remaining
directors theretofore elected by the holders of the class of capital stock which
elected the directors whose office shall have become vacant.  If any new
directorship is created by increase in the number of directors, a majority of
the directors then in office may fill such new directorship.  The term of office
of any director so chosen to fill a vacancy or a new directorship shall
terminate upon the election and qualification of directors at any meeting of
stockholders called for the purpose of electing directors.

     Section 11.  Compensation of Directors.  Directors may receive a fee, as
fixed by the Chairman of the Board, for their services, together with expenses
for attendance at regular or special meeting of the board.  Members of
committees of the board of directors may be allowed compensation for attending
committee meetings.  Nothing herein contained shall be construed to preclude any
director from serving the Company or any subsidiary thereof in any other
capacity and receiving compensation therefor.

                                  ARTICLE IV.

the committee present at the meeting shall be necessary for the adoption of any
resolution.

     Section 2.  Membership and Powers.  The executive committee shall consist

     In case any officer of the Company who shall have signed, or whose
facsimile signature shall have been used on, any certificate for shares of
capital stock of the Company shall cease to be such officer, whether because of
death, resignation or otherwise, before such certificate shall have been
delivered by the Company, such certificate shall nevertheless be deemed to have
been adopted by the Company and may be issued and delivered as though the person
who signed such certificate or whose facsimile signature shall have been used
thereon had not ceased to be such officer.

     Section 4.  Designations, Preferences, etc. on Certificates for Stock.
Certificates for shares of capital stock of the Company shall state on the face
or back thereof that the Company will furnish without charge to each stockholder
who so requests (which request may be addressed to the Secretary of the Company
or to a transfer agent) a statement of the designations, preferences and
relative, participating, optional or other special rights of each class of stock
or series thereof which the Company is authorized to issue and the
qualifications, limitations or restrictions of such preferences and/or rights.

     Section 5.  Stock Ledger.  A record shall be kept by the Secretary or by
any other officer, employee or agent designated by the board of directors of the
name of the person, firm, or corporation holding the stock represented by such
certificates, the number of shares represented by such certificates,
respectively, and the respective dates thereof, and in case of cancellation the
respective dates of cancellation.

     Section 6.  Cancellation.  Every certificate surrendered to the Company for
exchange or transfer shall be canceled, and no new certificate or certificates
shall be issued in exchange for any existing certificate until such existing
certificate shall have been so canceled.

     Section 7.  Transfers of Stock.  Transfers of shares of the capital stock
of the Company shall be made only on the books of the Company by the registered
holder thereof or by his attorney thereunto authorized on surrender of the
certificate or certificates for such shares properly endorsed and the payment of
all taxes thereon.  The person in whose name shares of stock stand on the books
of the Company shall be deemed the owner thereof for all purposes as regards the
Company; provided, however, that whenever any transfer of shares shall be made
for collateral security, and not absolutely, such fact, if known to the
Secretary or the transfer agent making such transfer, shall be so expressed in
the entry of transfer.

     Section 8.  Closing of Transfer Books.  The board of directors may by
resolution direct that the stock transfer books of the Company be closed for a
period not exceeding 60 days preceding the date of any meeting of the
stockholders, or the date for the payment of any dividend, or the date for the
allotment of any rights, or the date when any change or conversion or exchange
of capital stock of the company shall go into effect, or for a period not
exceeding 60 days in connection with obtaining the consent of stockholders for
any purpose.  In lieu of such closing of the stock transfer books, the board may
fix in advance a date, not exceeding 60 days preceding the date of any meeting
of stockholders, or the date for the payment of any dividend, or the date for
the allotment of rights, or the date when any change or conversion or exchange
of capital stock shall go into effect or a date in connection with obtaining
such consent, as a record

                                   Ex. 3.2-8
<PAGE>
 
date for the determination of the stockholders entitled to notice of, and to
vote at, such meeting, and any adjournment thereof, or to receive payment of any
such dividend, or to receive any such allotment of rights, or to exercise the
rights in respect of any such change, conversion, or exchange of capital stock
or to give such consent, as the case may be, notwithstanding any transfer of any
stock on the books of the Company after any record date so fixed.

                                  ARTICLE VII.

                           Miscellaneous Provisions.

     Section 1.  Corporate Seal.  The board of directors shall provide a
corporate seal which shall be in the form of a circle and shall bear the name of
the Company and words and figures showing that it was incorporated in the State
of Delaware in the year 1964.  The Secretary shall be the custodian of the seal.
The board of directors may authorize a duplicate seal to be kept and used by any
other officer.

     Section 2.  Fiscal Year.  The fiscal year of the Company shall be fixed by
resolution of the board of directors.

     Section 3.  Voting of Stocks Owned by the Company.  The board of directors
may authorize any person in behalf of the Company to attend, vote and grant
proxies to be used at any meeting of stockholders of any corporation in which
the Company may hold stock.

     Section 4.  Dividends.  Subject to the provisions of the certificate of
incorporation, the board of directors may, out of funds legally available
therefor, at any regular or special meeting declare dividends upon the capital
stock of the Company as and when they deem expedient.  Dividends may be paid in
cash, in property, or in shares of capital stock of the Company, subject to the
provisions of the certificate of incorporation.  Before declaring any dividend
there may be set apart out of any funds of the Company available for dividends
such sum or sums as the directors from time to time in their discretion deem
proper for working capital or as a reserve fund to meet contingencies or for
equalizing dividends or for such other purposes as the directors shall deem
conducive to the interests of the Company.

                                 ARTICLE VIII.

                    Indemnification of Officers, Directors,
                        Employees and Agents; Insurance.

     Section 1.  Indemnification.

     (a)  The Company may indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative
(including an action by or in the right of the Company) by reason of the fact
that he is or was a director, officer, employee or agent of the Company, or is
or was serving at the request of the Company as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise, against expenses (including attorneys' fees) and, except for an
action by or in the right of the Company, judgments, fines and amounts paid in
settlement, actually and reasonably incurred by him in connection with such
action, suit or proceeding, if he acted in good faith and in a manner he
reasonably believed to be

                                   Ex. 3.2-9
<PAGE>
 
in or not opposed to the best interests of the Company, and, with respect to any
criminal action or proceeding, had no reasonable cause to believe his conduct
was unlawful.  Except for an action by or in the right of the Company, the
termination of any action, suit or proceeding by judgment, order, settlement,
conviction, or upon a plea of nolo contendere or its equivalent, shall not, of
itself, create a presumption that the person did not act in good faith and in a
manner which he reasonably believed to be in or not opposed to the best
interests of the Company, and, with respect to any criminal action or
proceeding, had reasonable cause to believe that his conduct was unlawful. With
respect to an action by or in the right of the Company, no indemnification shall
be made in respect of any claim, issue or matter as to which such person shall
have been adjudged to be liable for negligence or misconduct in the performance
of his duty to the Company unless and only to the extent that the Delaware Court
of Chancery or the court in which such action or suit was brought shall
determine upon application that, despite the adjudication of liability but in
view of all the circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses which such court shall deem proper.

     (b)  To the extent that a director, officer, employee or agent of the
Company has been successful on the merits or otherwise in defense of any action,
suit or proceeding referred to in subsection (a) or in defense of any claim,
issue or matter therein, he shall be indemnified against expenses (including
attorneys' fees) actually and reasonably incurred by him in connection
therewith.

     (c)  Any indemnification under subsection (a) (unless ordered by a court)
shall be made by the Company only as authorized in the specific case upon a
determination that indemnification of the director, officer, employee or agent
is proper in the circumstances because he has met the applicable standard of
conduct set forth in subsection (a).  Such determination shall be made (i) by
the board of directors by a majority vote of a quorum consisting of directors
who were not parties to such action, suit or proceeding, or (ii) if such a
quorum is not obtainable, or, even if obtainable a quorum of disinterested
directors so directs, by independent legal counsel in a written opinion, or
(iii) by the stockholders.

     (d)  Expenses incurred in defending a civil or criminal action, suit or
proceeding may be paid by the Company in advance of the final disposition of
such action, suit or proceeding as authorized by the board of directors in the
manner provided in subsection (c) upon receipt of an undertaking by or on behalf
of the director, officer, employee or agent to repay such amount unless it shall
ultimately be determined that he is entitled to be indemnified by the Company as
authorized in this section.

     (e)  The indemnification provided by this Article shall not be deemed
exclusive of any other rights to which those seeking indemnification may be
entitled under any agreement, vote of stockholders or disinterested directors or
otherwise, both as to action in their official capacities and as to action in
other capacities while holding such offices, and shall continue as to a person
who has ceased to be a director, officer, employee or agent and shall inure to
the benefit of the heirs, executors and administrators of such a person.

     Section 2.  Insurance.  The Company may purchase and maintain insurance on
behalf of any person who is or was a director, officer, employee or agent of the
Company, or is or was serving at the request of the Company as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise against any liability asserted against him and
incurred by him in any such capacity, or arising out of his status as such,
whether or not the Company would have the power to indemnify him against such
liability under the provisions of either the General Corporation Law of the
State of Delaware or of these bylaws.

                                  ARTICLE IX.

                                  Amendments.

     The bylaws of the Company may be altered, amended or repealed either by the
affirmative vote of a majority of the stock issued and outstanding and entitled
to vote in respect thereof and represented in person or by proxy at any annual
or special meeting of the stockholders, or by the affirmative vote of a majority
of the directors then in office given at any regular or special meeting of the
board of directors.  Bylaws, whether made or altered by the stockholders or by
the board of directors, shall be subject to alteration or repeal by the
stockholders as in this Article provided.

any), minus (d) the lesser of (i) the net equity investment in any asset
financed or encumbered by Non-Recourse Debt, and (ii) the amount of Non-Recourse
Debt related to such asset.  In determining Adjusted Consolidated
Capitalization, the calculation set forth above shall be adjusted for any

copyrights, patents, and unamortized debt discount, (B) deferred taxation, and
(C) any amount referred to in this definition that relates to a minority
interest.  All determinations required by this definition shall be made in

Funds Effective Rate for any reason, including the inability of Domestic
Administrative Agent to obtain sufficient quotations in accordance with the
terms hereof, then the Alternate Base Rate shall be determined without regard to

For purposes of the foregoing: (a) if neither Moody's nor S&P shall have in
effect a rating for Index Debt (other than by reason of the circumstances
referred to in the last sentence of this definition), then both such rating
agencies will be deemed to have established ratings for Index Debt in Category
6; (b) if only one of Moody's or S&P shall have in effect a rating for Index
Debt, then Murphy and Lenders will negotiate in good faith to agree upon another
rating agency to be substituted by an amendment to this Agreement for the rating
agency which shall not have a rating in effect, and in the absence of such
amendment the Applicable Margin will be determined by reference to the available
rating; (c) if the ratings established by Moody's and S&P shall fall within
different Categories, then the Applicable Margin shall be determined by
reference to the numerically lower Category (for example, if the rating from S&P
is in Category 1 and the rating from Moody's is in Category 2, then the
Applicable Margin shall be determined by reference to Category 1); and (d) if
any rating established by Moody's or S&P shall be changed (other than as a
result of a change in the rating system of either Moody's or S&P), then such
change shall be effective as of the date on which such change is first announced
by the rating agency making such change.  Each change in the Applicable Margin
shall apply during the period commencing on the effective date of such change
and ending on the date immediately preceding the effective date of the next such
change.  If the rating system of either Moody's or S&P shall change prior to the
Maturity Date, then Murphy and Lenders shall negotiate in good faith to amend
the references to specific ratings in this definition to reflect such changed
rating system.  If both Moody's and 


                                   Ex. 4.1-3
<PAGE>
 
S&P shall cease to be in the business of rating corporate debt obligations, then

to reflect the ratings used by such substitute rating agency.

     Percentage times the Domestic Usage, shall not at any time exceed such
     Lender's Global Commitment then in effect;

          (vi)  the product of each Canadian Lender's Canadian Commitment
     Percentage times the Canadian Usage shall not exceed the lesser of such
     Lender's (A) Maximum Canadian Commitment, and (B) Current Canadian
     Commitment; and

          (vii) the product of each Domestic Lender's Domestic Commitment
     Percentage times the Domestic Usage shall not exceed such Lender's Domestic
     Commitment.

    (f) REVOLVING FACILITY.  Within the limits and on the conditions set forth
in this Agreement, Borrowers may from time to time borrow under this SECTION
2.1, prepay under SECTION 2.7(b) and SECTION 2.7(c) or SECTION 2.16(h)(ii), and
reborrow under this SECTION 2.1.

                                  Ex. 4.1-16
<PAGE>
 
     (g)  CURRENCY OPTIONS.  The Advances may from time to time be (i) U.S.
Dollar Base Rate Advances, (ii) U.S. Dollar Eurocurrency Rate Advances, (iii)
Canadian Dollar Base Rate Advances, or (iv) Pounds Sterling Eurocurrency Rate
Advances, or a combination thereof, as determined by the applicable Borrower and
notified to the Applicable Agent in accordance with SECTIONS 2.1, 2.2, or 2.3.

     2.2  MAKING ADVANCES.

     (a)  NOTICE OF BORROWING.  Each Borrowing (other than Borrowings made
pursuant to SECTION 2.16 for the purpose of reimbursing any Lender for the Face
Amount of any matured Bankers' Acceptance) shall be made pursuant to a Notice of
Borrowing, given (i) in the case of a Borrowing consisting of U.S. Dollar Base
Rate Advances made or to be made by Domestic Lenders, not later than 11:00 a.m.
(New York City time) on the date of the proposed Borrowing, (ii) in the case of
a Borrowing consisting of U.S. Dollar Eurocurrency Rate Advances made or to be
made by Domestic Lenders, not later than 11:00 a.m. (New York City time) three
(3) Business Days prior to the date of the proposed Borrowing, (iii) in the case
of a Borrowing consisting of Canadian Dollar Base Rate Advances, not later than
11:00 a.m. (Toronto, Ontario time) on the date of the proposed Borrowing, (iv)
in the case of a Borrowing consisting of U.S. Dollar Base Rate Advances made or
to be made by Canadian Lenders, not later than 11:00 a.m. (Toronto, Ontario
time) on the date of the proposed Borrowing, (v) in the case of a Borrowing
consisting of U.S. Dollar Eurocurrency Rate Advances made or to be made by
Canadian Lenders, not later than 11:00 a.m. (Toronto, Ontario time) three (3)
Business Days prior to the date of the proposed Borrowing, and (vi) in the case
of a Borrowing consisting of Pounds Sterling Eurocurrency Rate Advances, not
later than 11:00 a.m. (London, England time) three (3) Business Days prior to
the date of the proposed Borrowing, by the requesting Borrower to the Applicable
Agent, which shall give to each Applicable Lender prompt notice thereof by cable
or telecopy. Each Notice of a Borrowing shall specify (A) the Borrower
requesting the Borrowing, (B) the date of such Borrowing, (C) whether such
Borrowing will be denominated in Canadian Dollars, U.S. Dollars, or, in the case
of a Domestic Borrower, Pounds Sterling, (D) the Type of Advances comprising
such Borrowing, (E) the amount of such Borrowing, and (F) if applicable, the
Interest Period.  Each Domestic Lender shall, before 12:00 noon (New York City
time) on the date of any such Borrowing, make available for the account of its
Applicable Lending Office to Domestic Administrative Agent at its address
referred to in SECTION 10.2, in same day funds, such Domestic Lender's
Applicable Commitment Percentage of such Borrowing in the Applicable Currency.
Each Canadian Lender shall, before 12:00 noon (Toronto, Ontario time) on the
date of any such Borrowing, make available for the account of its Applicable
Lending Office to Canadian Administrative Agent at its address referred to in
SECTION 10.2, in same day funds, such Canadian Lender's Applicable Commitment
Percentage of such Borrowing in the Applicable Currency.  Upon the Applicable
Agent's receipt of such funds and upon fulfillment of the conditions precedent
set forth in SECTION 3.2, the Applicable Agent will make such funds available to
the applicable Borrower at the Applicable Agent's aforesaid address.

     (b)  NOTICES IRREVOCABLE.  Each Notice of Borrowing shall be irrevocable
and binding on the requesting Borrower.  In the case of any Borrowing which the
related Notice of Borrowing specifies is to be comprised of Eurocurrency Rate
Advances, the requesting Borrower shall indemnify each Lender against any loss,
cost, or expense incurred by such Lender as a result of any failure by such
Borrower to complete such Borrowing, which losses, costs, and expenses include,
without limitation, any loss (including loss of anticipated profits), cost, or
expense incurred by reason of the liquidation or reemployment of deposits or
other funds acquired by such Lender to fund the Advance to be made by such
Lender as part of such Borrowing when such Advance is not made on such date.

     (c)  FUNDING; FAILURE TO FUND.  Unless the Applicable Agent shall have
received notice from a Lender prior to the date of any Borrowing that such
Lender will not make available to the Applicable Agent such Lender's Applicable
Commitment Percentage of such Borrowing in the Applicable Currency, the
Applicable Agent may assume that each Applicable Lender has made such portion
available to the Applicable 

                                  Ex. 4.1-17
<PAGE>
 
Agent on the date of such Borrowing in accordance with SECTION 2.2(a), and the
Applicable Agent may, in reliance upon such assumption, make available to the
requesting Borrower on such date a corresponding amount. If and to the extent
that any Applicable Lender shall not have so made such Applicable Commitment
Percentage available to the Applicable Agent, then such Applicable Lender and
the requesting Borrower (following such Applicable Lender's failure to pay
following demand by the Applicable Agent) severally agree to repay to the
Applicable Agent forthwith on demand such corresponding amount, together with
interest thereon, for each day from the date such amount is made available to
such Borrower until the date such amount is repaid to the Applicable Agent, at a
rate per annum equal to (i) in the case of such Borrower, the interest rate
applicable at the time to Advances comprising such Borrowing, (ii) in the case
of any Domestic Lender, an interest rate equal at all times to the Federal Funds
Effective Rate, and (iii) in the case of any Canadian Lender, an interest rate
equal at all times to the Cost of Funds Rate. If such Applicable Lender shall
advance to the Applicable Agent such corresponding amount, then such amount so
repaid shall constitute such Applicable Lender's Advance as part of such
Borrowing for purposes of this Agreement. If such Borrower shall repay such
corresponding amount, then the Applicable Lender shall remain liable to pay to
the Applicable Agent an amount equal to the difference, if any, between the
amount payable by such Applicable Lender pursuant to (ii) or (iii) of this
SECTION 2.2(c), as the case may be, and the amount so repaid by such Borrower.
The interest payable by any Lender to any Agent pursuant to this SECTION shall
not affect the interest otherwise payable by the applicable Borrower pursuant to
SECTION 2.8.

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

     2.3  CONVERSION AND CONTINUATION OF BORROWINGS.  Any Domestic Borrower
shall have the right at any time upon prior irrevocable notice to Domestic
Administrative Agent (a) not later than 12:00 noon (New York City time) on the
date of conversion, to convert any Borrowing consisting of U.S. Dollar
Eurocurrency Rate Advances into a Borrowing consisting of U.S. Dollar Base Rate
Advances, (b) not later than 11:00 a.m. (New York City time) three (3) Business
Days prior to conversion or continuation, to convert any Borrowing consisting of
U.S. Dollar Base Rate Advances into a Borrowing consisting of U.S. Dollar
Eurocurrency Rate Advances or to continue any Borrowing consisting of U.S.
Dollar Eurocurrency Rate Advances for an additional Interest Period, and (c) not
later than 11:00 a.m. (London, England time) three (3) Business Days prior to
continuation, to continue any Borrowing consisting of Pounds Sterling
Eurocurrency Rate Advances for an additional Interest Period.  Canadian Borrower
shall have the right at any time upon prior irrevocable notice to Canadian
Administrative Agent (a) not later than 11:00 a.m. (Toronto, Ontario time) on
the date of conversion, to convert any Borrowing consisting of U.S. Dollar
Eurocurrency Rate Advances into a Borrowing consisting of U.S. Dollar Base Rate
Advances, and (b) not later than 11:00 a.m. (Toronto, Ontario time) three (3)
Business Days prior to conversion or continuation, to convert any Borrowing
consisting of U.S. Dollar Base Rate Advances into a Borrowing consisting of U.S.
Dollar Eurocurrency Rate Advances or continue any Borrowing consisting of U.S.
Dollar Eurocurrency Rate Advances for an additional Interest Period.  Each
conversion or continuation described above is subject to the following:

          (i)    each conversion or continuation shall be made pro rata among
     Lenders in accordance with the respective principal amounts of the Advances
     comprising the converted or continued Borrowing;

          (ii)   if less than all the outstanding principal amount of any
     Borrowing shall be converted or continued, the aggregate principal amount
     of such Borrowing converted or continued shall be an amount equal to or
     greater than $7,500,000;

                                  Ex. 4.1-18
<PAGE>
 
          (iii)  accrued interest on an Advance being converted shall be paid by
     such Borrower at the time of conversion;

          (iv)   if any Borrowing consisting of Eurocurrency Rate Advances is
     converted at a time other than the end of the Interest Period applicable
     thereto, then the applicable Borrower shall pay, upon demand, any amounts
     due to Lenders pursuant to SECTION 2.10(C) as a result of such conversion;

          (v)    no Interest Period may be selected for any Borrowing 
     consisting of Eurocurrency Rate Advances that would end later than the
     Maturity Date; and

          (vi)   no more than ten (10) Interest Periods shall be in effect with
     respect to U.S. Dollar Eurocurrency Rate Advances to Domestic Borrowers, no
     more than ten (10) Interest Periods shall be in effect with respect to U.S.
     Dollar Eurocurrency Rate Advances to Canadian Borrower, and no more than
     six (6) Interest Periods shall be in effect with respect to Pounds Sterling
     Eurocurrency Rate Advances to Domestic Borrowers.

     Each notice pursuant to this SECTION 2.3 shall be irrevocable and shall
refer to this Agreement and specify (A) the applicable Borrower, (B) the
identity and amount of the Borrowing that the applicable Borrower requests be
converted or continued, (C) whether such Borrowing is to be converted to or
continued as a Borrowing consisting of U.S. Dollar Base Rate Advances or
Eurocurrency Rate Advances, as the case may be, (D) if such notice requests a
conversion, the date of such conversion (which shall be a Business Day), and (E)
if such Borrowing is to be converted to or continued as a Borrowing consisting
of Eurocurrency Rate Advances, then the Interest Period with respect thereto.
If no Interest Period is specified in any such notice with respect to any
conversion to or continuation as a Borrowing consisting of Eurocurrency Rate
Advances, then such Borrower shall be deemed to have selected an Interest Period
of one (1) month's duration.  The Applicable Agent shall advise Lenders of any
notice given pursuant to this SECTION 2.3 and of each Lender's Applicable
Commitment Percentage of any converted or continued Borrowing.  If any Borrower
shall not have given notice in accordance with this SECTION 2.3 to continue any
Borrowing into a subsequent Interest Period (and shall not otherwise have given
notice in accordance with this SECTION 2.3 to convert such Borrowing), then (x)
in the case of U.S. Dollar Eurocurrency Rate Advances, such Borrowing shall, at
the end of the Interest Period applicable thereto (unless repaid pursuant to the
terms hereof), automatically be continued into a Borrowing consisting of U.S.
Dollar Base Rate Advances, and (y) in the case of Pounds Sterling Eurocurrency
Rate Advances, the applicable Borrower shall be deemed to have requested a U.S.
Dollar Base Rate Advance in an amount equal to the Dollar Equivalent of such
Pounds Sterling Eurocurrency Rate Advances, the proceeds of which shall, subject
to the conditions precedent in SECTION 3.2, be applied to the repayment of such
Pounds Sterling Eurocurrency Rate Advances at the end of the Interest Period
applicable thereto (unless otherwise repaid pursuant to the terms hereof).

     2.4  LOAN ACCOUNTS.

     (a)  BY EACH LENDER.  Each Lender shall maintain on its books loan accounts
in the name of each Borrower in which shall be recorded all Advances made by
such Lender to each Borrower, the interest rate, the currency, and the maturity
date of each such Advance and all payments of principal and interest made by
each Borrower with respect to such Advances.

     (b)  BY AGENTS.  Domestic Administrative Agent shall maintain on its books
a set of accounts in which shall be recorded all Advances made by Domestic
Lenders to each Domestic Borrower, the interest rates, the currency, and
maturity dates of such Advances and all payments of principal and interest made
thereon. Canadian Administrative Agent shall maintain on its books a set of
accounts in which shall be recorded all Advances made by Canadian Lenders to
Canadian Borrower, the interest rates, the currency, and

                                  Ex. 4.1-19
<PAGE>
 
maturity dates of such Advances and all payments of principal and interest made
thereon.

     (c)  EVIDENCE OF AMOUNT.  The loan accounts or records maintained by Agents
and each Lender shall be conclusive evidence absent manifest error of the amount
of the Advances made by Lenders to Borrowers and the interest and payments
thereon.  Any failure to so record or any error in doing so shall not, however,
limit or otherwise affect the obligation of any Borrower hereunder to pay any
amount owing by such Borrower with respect to the Advances received by such
Borrower.

     (d)  NOTES.  Upon the request of any Lender made through the Applicable
Agent, the Advances made by such Lender may be evidenced by one or more notes in
substantially the form of EXHIBIT F, instead of or in addition to loan accounts.
Each such Lender shall endorse on the schedules annexed to its note(s) the date,
amount, and maturity of each Advance made by it and the amount of each payment
of principal made by Borrowers with respect thereto.  Each such Lender is
irrevocably authorized by Borrowers to endorse its note(s) and each Lender's
record shall be conclusive absent manifest error; provided, however, that the
failure of a Lender to make, or an error by a Lender in making, a notation
thereon with respect to any Advance shall not limit or otherwise affect the
obligation of any Borrower hereunder or under any such Note to such Lender with
respect to any Advances received and not repaid.

     2.5  FEES.

     (a)  FACILITY FEES.  Murphy shall pay to Domestic Administrative Agent, for
the benefit of Domestic Lenders, a facility fee on the average daily amount of
the Domestic Commitments (whether used or unused) for the period from and
including the date hereof up to but excluding the Termination Date at a rate per
annum equal to the Applicable Margin for Facility Fees.  Murphy (on behalf of
Canadian Borrower) shall pay to Canadian Administrative Agent, for the benefit
of Canadian Lenders, a facility fee on the average daily amount of the Current
Canadian Commitments (whether used or unused) for the period from and including
the date hereof up to but excluding the Termination Date at a rate per annum
equal to the Applicable Margin for Facility Fees.  Accrued facility fees shall
be payable in arrears, commencing on December 31, 1997, and thereafter,
quarterly on the last day of each March, June, September, and December during
the term hereof and on the Termination Date.

     (b)  FEES OF DOMESTIC ADMINISTRATIVE AGENT AND ARRANGER.  Murphy shall pay
to Domestic Administrative Agent and Arranger, solely for their own respective
accounts, the fees described in the separate letter agreement dated September
30, 1997 among Murphy, Domestic Administrative Agent, and Arranger on the dates
specified therein.

     2.6  OPTIONAL REDUCTION OF THE COMMITMENTS.  Murphy shall have the right,
upon at least two (2) Business Days' irrevocable notice to Agents, to terminate
in whole or reduce ratably in part the Global Commitments; provided, however,
that (a) each partial reduction shall be in the aggregate amount of $10,000,000
or a greater integral multiple of $1,000,000, (b) no such termination or
reduction shall be made which would reduce the Global Commitments to an amount
less than the Total Utilization of Commitments, and (c) any partial reduction of
the Global Commitments shall reduce the Maximum Canadian Commitments by an
amount equal to fifty percent (50%) of the amount of the reduction in the Global
Commitments. Agents shall promptly thereafter notify each Lender of such
termination or reduction.  No reduction shall reduce the Maximum Canadian
Commitments to an amount that is less than the Canadian Usage, or the Domestic
Commitments to an amount that is less than the Domestic Usage.  Murphy's notice
to Agents shall designate the date (which shall be a Business Day) of such
termination or reduction and the amount of any partial reduction.  Any such
termination or reduction of the Global Commitments shall be effective on the
date specified in Murphy's notice and shall reduce the Global Commitment of each
Lender, the Domestic Commitment of each Domestic Lender, and, if necessary, the
Canadian Commitment of each Canadian Lender, ratably in accordance with its
Percentage Share.

                                  Ex. 4.1-20
<PAGE>
 
     2.7  REPAYMENT OF ADVANCES; PREPAYMENT.

     (a)  TERMINATION DATE.  On the Termination Date, each Domestic Borrower
shall repay to Domestic Administrative Agent, in the Applicable Currency and for
the account of each Domestic Lender, the unpaid principal amount of each
Domestic Advance to such Domestic Borrower made by each Domestic Lender.  On the
Termination Date, each Canadian Borrower shall repay to Canadian Administrative
Agent, in the Applicable Currency and for the account of each Canadian Lender,
the unpaid principal amount of each Canadian Advance to such Canadian Borrower
made by each Canadian Lender.

     (b)  VOLUNTARY PREPAYMENTS.  Any Borrower may, on notice given to the
Applicable Agent (i) in the case of U.S. Dollar Base Rate Advances made by
Domestic Lenders, not later than 11:00 a.m. (New York City time) on the date of
the proposed prepayment, (ii) in the case of U.S. Dollar Eurocurrency Rate
Advances made by Domestic Lenders, not later than 11:00 a.m. (New York City
time) three (3) Business Days prior to the day of the proposed prepayment, (iii)
in the case of U.S. Dollar Base Rate Advances made by Canadian Lenders, not
later than 11:00 a.m. (Toronto, Ontario time) on the date of the proposed
prepayment, (iv) in the case of U.S. Dollar Eurocurrency Rate Advances made by
Canadian Lenders, not later than 11:00 a.m. (Toronto, Ontario time) three (3)
Business Days prior to the date of the proposed prepayment, (v) in the case of
Canadian Dollar Base Rate Advances, not later than 11:00 a.m. (Toronto, Ontario
time) on the date of the proposed prepayment, and (vi) in the case of Pounds
Sterling Eurocurrency Rate Advances, not later than 11:00 a.m. (New York City
time) three (3) Business Days prior to the day of the proposed prepayment,
stating the proposed date and aggregate principal amount of the prepayment, and
if such notice is given, then such Borrower shall prepay the outstanding
principal amounts of the Advances constituting part of the same Borrowing in
whole or ratably in part; provided, however, that any such partial prepayment
shall be in an aggregate principal amount not less than the Dollar Equivalent of
U.S. $7,500,000 (or, if less, the unpaid principal of such Advance), and
provided further, that any such prepayment of Eurocurrency Rate Advances shall
be subject to the provisions of SECTION 2.10(c).  The Applicable Agent shall
promptly notify each Lender of any prepayments pursuant to this SECTION 2.7(b)
promptly after receipt of any such prepayment.  Borrowers shall have no right to
prepay any principal amount of any Advance except as expressly set forth in this
SECTION 2.7(b) and as required by SECTION 2.7(c).  If any Borrower shall repay
all or any portion of any Eurocurrency Rate Advance on the last day of the
Interest Period therefor, then such repayment shall be considered to be a
prepayment pursuant to this SECTION 2.7(b).

     (c)  MANDATORY PREPAYMENTS.  If as of the last day of any calendar quarter
or the date of any Advance (i) the sum of (A) the outstanding amount of all
Borrowings (valued in Dollar Equivalents), plus (B) the BA Usage (valued in
Dollar Equivalents) exceeds the Global Commitments in effect on such date, (ii)
the Canadian Usage exceeds the Designated Canadian Commitment, or (iii) the
Domestic Usage exceeds the Domestic Commitments, then Borrowers shall prepay
Borrowings in an amount equal to any such excess.

     2.8  INTEREST.  Each Borrower shall pay interest on each Advance to such
Borrower made by each Lender from the date of such Advance until paid in full,
as follows:

     (a)  RATE ON ADVANCES.  The unpaid principal of each Advance shall bear
interest from the date of Advance to the date of repayment thereof at a rate per
annum that shall be equal to the Applicable Rate.

     (b)  DEFAULT AMOUNTS.  All past-due amounts of the principal of, and (to
the fullest extent permitted by law) interest on, any Advance or the Face Amount
of any Bankers' Acceptance not reimbursed in full on the maturity date of such
Bankers' Acceptance shall bear interest from the date such amount becomes due
until paid in full, payable on demand, at a rate per annum equal at all times to
the lesser of: (i) the Maximum Rate; and (ii) in the case of (A) Canadian Dollar
Base Rate Advances and the unreimbursed Face Amount of any Bankers' Acceptance,
the sum of the Canadian Dollar Base Rate in effect from time to time plus one
percent (1%), (B) Pounds Sterling Eurocurrency Rate Advances, the sum of the
Applicable 

                                  Ex. 4.1-21
<PAGE>
 
Rate plus one percent (1%), and (C) all other Advances, the sum of the Alternate
Base Rate in effect from time to time plus one percent (1%).

     (c)  PAYMENT OF INTEREST ON ADVANCES.   Interest on each Eurocurrency Rate
Advance shall be due and payable as it accrues on the last day of its respective
Interest Period; provided that if any Interest Period is a period greater than
three (3) months, then accrued interest shall also be due and payable on the
date that is three (3) months after the commencement of such Interest Period.
Interest on each U.S. Dollar Base Rate Advance and each Canadian Dollar Base
Rate Advance shall be due and payable as it accrues on the last day of each
March, June, September, and December, commencing on December 31, 1997, and on
the Termination Date.

     2.9  LIMITATION ON EUROCURRENCY RATE ADVANCES.

     (a)  INADEQUACY.  If the Required Lenders shall notify the Applicable Agent
that the Eurocurrency Rate for any Eurocurrency Rate Borrowing will not
adequately reflect the cost to the Required Lenders of making or funding their
respective Eurocurrency Rate Advances for such Eurocurrency Rate Borrowing, then
the right of Borrowers to select Eurocurrency Rate Advances for any subsequent
Borrowing shall be suspended until the Applicable Agent notifies Murphy and
Lenders that the circumstances causing such suspension no longer exist, and any
request by any Borrower for a Eurocurrency Rate Advance shall be deemed to be a
request for a U.S. Dollar Base Rate Advance.

     (b)  BASIS UNAVAILABLE.  If, on or prior to the determination of any
Eurocurrency Rate for any Interest Period, the Applicable Agent determines
(which determination shall be conclusive, absent manifest error) that quotations
of interest rates provided in the definition of "Eurocurrency Rate" in SECTION
1.1 are not being provided for the relevant maturities for purposes of
determining rates of interest for Eurocurrency Rate Advances as provided herein,
then the Applicable Agent shall give Murphy prompt notice thereof, and so long
as such condition remains in effect, the Applicable Lenders shall be under no
obligation to make additional Eurocurrency Rate Advances or continue or convert
into Eurocurrency Rate Advances.

     2.10 INCREASED COSTS; INCREASED CAPITAL; PREPAYMENTS.

     (a)  INCREASED COSTS.  If due to either (i) the passage of or any change
after the date hereof (other than any change by way of imposition or increase of
reserve requirements included in the Eurocurrency Rate Reserve Percentage) in or
in the interpretation of any Legal Requirement, or (ii) the compliance with any
guideline received from any central bank or other Governmental Authority after
the date hereof (whether or not having the force of law), there shall be any
increase in the cost to any Lender of agreeing to make or making, funding, or
maintaining Eurocurrency Rate Advances, then the applicable Borrowers shall from
time to time, upon demand by such Lender (with a copy of such demand to the
Applicable Agent), pay to the Applicable Agent for the account of such Lender
additional amounts sufficient to compensate such Lender for such increased cost.
Increased costs shall not include income, stamp, or other taxes, imposts,
duties, charges, fees, deductions, or withholdings imposed, levied, collected,
withheld, or assessed by the United States of America or Canada or any political
subdivision or taxing authority thereof or therein (including Puerto Rico) or of
the country in which any Lender's principal office or Applicable Lending office
may be located or any political subdivision or taxing authority thereof or
therein.  Each Lender agrees that, upon the occurrence of any event giving rise
to a demand under this SECTION 2.10(a) with respect to the Eurocurrency Lending
Office of such Lender, it will, if requested by any Borrower and to the extent
permitted by law or the relevant Governmental Authority, endeavor in good faith
and consistent with its internal policies to avoid or minimize the increase in
costs resulting from such event by endeavoring to change its Eurocurrency
Lending Office; provided, however, that such avoidance or minimization can be
made in such a manner that such Lender, in its sole determination, incurs no
economic, legal, or regulatory disadvantage.  A certificate as to the amount of
and specifying in reasonable detail the basis for such increased cost, submitted
to such Borrower and the Applicable Agent by such Lender, shall constitute such
demand and shall, in the absence of manifest error, be 


                                  Ex. 4.1-22
<PAGE>
 
conclusive and binding for all purposes.

     (b)  CAPITAL.  If either (i) the passage of or any change after the date
hereof in or in the interpretation of, any Legal Requirement, or (ii) the
compliance by any Lender with any guideline received from any central bank or
other Governmental Authority after the date hereof (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 amount of such capital is increased
by or based upon the existence of its Advances or Commitment, then the
applicable Borrowers shall, from time to time, upon demand by such Lender (with
a copy of such demand to the Applicable Agent), immediately pay to the
Applicable Agent for the account of such Lender additional amounts sufficient to
compensate such Lender to the extent that such Lender determined such increase
in capital to be allocable to the existence of such Lender's Advances or
Commitment.  Each Lender agrees that, upon the occurrence of any event giving
rise to a demand under this SECTION 2.10(b) with respect to the Applicable
Lending Office of such Lender, it will, if requested by any Borrower and to the
extent permitted by law or the relevant Governmental Authority, endeavor in good
faith and consistent with its internal policies to avoid or minimize the
increase in cost resulting from such event by endeavoring to change its
Applicable Lending Office; provided, however, that such avoidance or
minimization can be made in such a manner that such Lender, in its sole
determination, incurs no economic, legal, or regulatory disadvantage.  A
certificate as to the amount of such increased capital and specifying in
reasonable detail the basis therefor, submitted to such Borrower and the
Applicable Agent by such Lender, shall constitute such demand and shall, in the
absence of manifest error, be conclusive and binding for all purposes.

     (c)  FUNDING LOSSES.  If any payment of principal of any Eurocurrency Rate
Advance is made by a Borrower to or for the account of a Lender other than on
the last day of the Interest Period for a Eurocurrency Rate Advance or as a
result of a payment pursuant to SECTION 2.7(b) or SECTION 2.7(c), or as a result
of acceleration of the maturity of the Advances pursuant to SECTION 7.2, or for
any other reason, or if any Borrower fails to convert or continue any Advance
hereunder after irrevocable notice of such conversion or continuation has been
given pursuant to SECTION 2.3, Borrowers shall, upon demand by such Lender (with
a copy of such demand to the Applicable Agent), pay to the Applicable Agent for
the account of such Lender any amounts required to compensate such Lender for
any losses, costs, or expenses which it may reasonably incur as a result of such
payment or failure, including, without limitation, any loss (including loss of
anticipated profits), cost, or expense incurred by reason of the liquidation or
reemployment of deposits or other funds acquired by such Lender to fund or
maintain such Advance.  A certificate of such Lender setting forth the amount
demanded hereunder and the basis therefor shall, in the absence of manifest
error, be conclusive and binding for all purposes.

     2.11 ADDITIONAL INTEREST ON EUROCURRENCY RATE ADVANCES.  Each Borrower
shall pay to the Applicable Agent, for the account of each Lender, any costs
which such Lender determines are attributable to such Lender's compliance with
regulations of the Board of Governors of the Federal Reserve System requiring
the maintenance of reserves with respect to liabilities or assets consisting of
or including Eurocurrency Liabilities.  Such costs shall be paid to the
Applicable Agent for the account of such Lender in the form of additional
interest on the unpaid principal amount of each Eurocurrency Rate Advance of
such Lender, from the later of (a) the date of such Advance, and (b) the
effective date of such reserve requirement under applicable regulations, until
such principal amount is paid in full, at an interest rate per annum equal at
all times to the remainder obtained by subtracting (i) the Eurocurrency Rate for
the applicable period for such Advance from (ii) the rate obtained by dividing
such Eurocurrency Rate by a percentage equal to one-hundred percent (100%) minus
the Eurocurrency Rate Reserve Percentage of such Lender for such period, payable
on each date on which interest is payable on such Advance.  Such additional
interest shall be determined by such Lender and notified to the Applicable
Agent.  A certificate setting forth the amount of such additional interest,
submitted to Borrowers and the Applicable Agent by such Lender, shall be
conclusive and binding for all purposes, absent manifest error.

     2.12 CHANGE IN LEGALITY.  If any Lender shall notify the Applicable Agent
that the passage of or any change after the date hereof in or in the
interpretation of any Legal Requirement makes it unlawful, or that any central
bank or other Governmental Authority asserts that it is unlawful, for such
Lender or any of its lending offices to perform its obligations hereunder to
make, fund, or maintain Eurocurrency Rate Advances hereunder, then the right of
any Borrower to select Eurocurrency Rate Advances from such Lender for any
Borrowing shall be suspended until such Lender shall notify the Applicable Agent
that the circumstances causing such suspension no longer exist.  If the
obligation of any Lender to make, continue, or convert into Eurocurrency Rate
Advances shall be suspended, then (a) all U.S. Dollar Eurocurrency Rate Advances
that would otherwise be made by such Lender shall be made instead as U.S. Dollar
Base Rate Advances, and (b) Pounds Sterling Eurocurrency Rate Advances from such
Lender shall be unavailable.  If such Lender so requests by notice to the
Applicable Agent, then (i) all U.S. Dollar Eurocurrency Rate Advances of such
Lender then outstanding shall be automatically converted into U.S. Dollar Base
Rate Advances on the date specified by such Lender in such notice, and, to the
extent that Eurocurrency Rate Advances are so made as (or converted into) U.S.
Dollar Base Rate Advances, all payments of principal which would otherwise be
applied to such Lender's Eurocurrency Rate Advances shall be applied instead to
its U.S. Dollar Base Rate Advances, and (ii) the applicable Borrower shall be
deemed to have requested U.S. Dollar Base Rate Advances in an amount equal to
the Dollar Equivalent of all outstanding Pounds Sterling Eurocurrency Rate
Advances, the proceeds of which shall be applied to the repayment of such Pounds
Sterling Eurocurrency Rate Advances.  Notwithstanding the foregoing, if any
Lender shall notify the Applicable Agent of the occurrence of the circumstances
described in this SECTION 2.12, then, provided that (A) no Event of Default
exists, and (B) the circumstances resulting in such notice are not applicable to
all Lenders, Borrowers may terminate the Commitments of such Lender in whole but
not in part, by either (1) (x) giving such Lender and the Applicable Agent not
less than five (5) Business Days' written notice thereof, which notice shall be
irrevocable and effective only upon receipt thereof by such Lender and the
Applicable Agent and shall specify the date of such termination, and (y) paying
such Lender on such date the outstanding principal of, and interest on, all
Advances made by such Lender and any other Obligation owed to such Lender, if
any, or (2) pursuant to the provisions of SECTION 10.7, proposing the
introduction of a replacement Lender satisfactory to Domestic Administrative
Agent, or obtaining the agreement of one or more existing Lenders, to assume the
entire amount of the Commitments of the Lender whose Commitments are being
terminated, on the effective date of such termination.  Upon the satisfaction of
all of the foregoing conditions, such Lender that is being terminated shall
cease to be a "Lender" for purposes of this Agreement, provided that Borrowers
shall continue to be obligated to such Lender under SECTION 10.15 with respect
to Indemnified Liabilities (as defined in such SECTION) arising prior to such
termination. If Borrowers terminate the Commitments of any Lender pursuant to
CLAUSE (1) above, then the Global Commitments and, as appropriate, the Maximum
Canadian Commitments shall be reduced accordingly.

     2.13 PAYMENTS AND COMPUTATIONS.

     (a)  PAYMENTS.  Domestic Borrowers shall make all payments in support of
any Borrowing denominated in any currency in the same currency and shall make
all payments not later than 11:00 a.m. (New York City time) on the date when due
to Domestic Administrative Agent, for the ratable benefit of Domestic Lenders,
at its address referred to in SECTION 10.2 in same-day funds.  Canadian Borrower
shall make all payments in support of any Borrowing or Bankers' Acceptance
denominated in any currency in the same currency and shall make all payments not
later than 11:00 a.m. (Toronto, Ontario time) on the date when due to Canadian
Administrative Agent, for the ratable benefit of Canadian Lenders, at its
address referred in SECTION 10.2 in same-day funds.  The Applicable Agent will
promptly thereafter cause to be distributed like funds to all Lenders entitled
thereto for the account of their respective Applicable Lending Offices, in each
case to be applied in accordance with the terms of this Agreement.

     (b)  COMPUTATIONS.  All computations of (i) interest on U.S. Dollar Base
Rate Advances, Canadian Dollar Base Rate Advances, and Pounds Sterling
Eurocurrency Rate Advances, and (ii) Facility 

                                  Ex. 4.1-24
<PAGE>
 
Fees shall be made by the Applicable Agent on the basis of a year of 365 or 366
days, as the case may be, and all computations of interest on U.S. Dollar
Eurocurrency Rate Advances shall be made by the Applicable Agent on the basis of
a year of 360 days, in each case for the actual number of days (including the
first (1st) day but excluding the last day) occurring in the period for which
such interest or fees are payable. Each determination by the Applicable Agent of
an interest rate hereunder shall be conclusive and binding for all purposes,
absent manifest error.

     (c)  INTEREST ACT (CANADA).  Whenever interest is calculated on the basis
of a year of 360 or 365 days, for the purposes of the Interest Act (Canada), the
yearly rate of interest which is equivalent to the rate payable hereunder is the
rate payable multiplied by the actual number of days in the year and divided by
360 or 365, as the case may be.  All interest shall be calculated using the
nominal rate method and not the effective rate method and the deemed
reinvestment principle shall not apply to such calculations.

     (d)  BUSINESS DAYS.  Whenever any payment hereunder 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 be included in the
computation of payment of interest or fees, as the case may be; provided,
however, that, if such extension would cause payment of interest on or principal
of Eurocurrency Rate Advances to be made in the next following calendar month,
then such payment shall be made on the next preceding Business Day.

     (e)  DISTRIBUTION OF PAYMENTS.  Unless the Applicable Agent shall have
received notice from any Borrower prior to the date on which any payment is due
to Lenders hereunder that such Borrower will not make such payment in full, the
Applicable Agent may assume that such Borrower has made such payment in full to
the Applicable Agent on such date and the Applicable 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 such
Borrower shall not have so made such payment in full to the Applicable Agent,
then (i) each Domestic Lender shall repay to Domestic Administrative Agent
forthwith on demand such amount distributed to such Domestic Lender together
with interest thereon, for each day from the date such amount is distributed to
such Domestic Lender until the date such Domestic Lender repays such amount to
Domestic Administrative Agent, at a per annum rate equal to the Federal Funds
Effective Rate, and (ii) each Canadian Lender shall repay to Canadian
Administrative Agent forthwith on demand such amount distributed to such
Canadian Lender together with interest thereon, for each day from the date such
amount is distributed to such Canadian Lender until the date such Canadian
Lender repays such amount to Canadian Administrative Agent, at a per annum
interest rate equal at all times to the Cost of Funds Rate.  The interest
payable by any Lender to any Agent pursuant to this SECTION shall not affect the
interest otherwise payable by the applicable Borrower pursuant to SECTION 2.8.

     2.14 TAXES ON PAYMENTS.

     (a)  WITHHOLDING TAXES.  All payments made by Borrowers under this
Agreement shall be made free and clear of, and without reduction for or on
account of, any income, stamp, or other taxes, imposts, duties, charges, fees,
deductions, or withholdings, imposed, levied, collected, withheld, or assessed
by the United States of America or Canada (or by any political subdivision or
taxing authority thereof or therein) as a result of (i) the introduction after
the date hereof of any law, regulation, treaty, directive, or guideline (whether
or not having the force of law), or (ii) any change after the date hereof in any
law, regulation, treaty, directive, or guideline (whether or not having the
force of law), or (iii) any change after the date hereof in the interpretation
or application of any law, regulation, treaty, directive, or guideline (whether
or not having the force of law), or (iv) any such taxes, imposts, duties,
charges, fees, deductions, or withholdings being imposed, levied, collected,
withheld, or assessed at a greater rate than the rate that would have been
applicable had such an introduction or change not been made, but only to the
extent of the increase in such rate ("WITHHOLDING TAXES").  If any Withholding
Taxes are required to be withheld from any amounts payable to or for the account
of any Lender hereunder, then the amounts so payable to or for the account of


                                  Ex. 4.1-25
<PAGE>
 
such Lender shall be increased to the extent necessary to yield to such Lender
(after payment of all Withholding Taxes including Withholding Taxes on all such
additional amounts) interest or any such other amounts payable hereunder at the
rates or in the amounts payable to or for the account of such Lender under this
Agreement prior to such introduction or change. Whenever any Withholding Taxes
are payable by any Borrower, as promptly as possible thereafter such Borrower
shall send to the Applicable Agent, for the account of such Lender, a certified
copy of an original official receipt showing payment thereof.  If such Borrower
fails to pay any Withholding Taxes when due to the appropriate taxing authority
or fails to remit to the Applicable Agent the required receipts or other
required documentary evidence, then such Borrower shall indemnify such Lender or
the Applicable Agent for any incremental taxes, interest, or penalties that may
become payable by such Lender or the Applicable Agent as a result of any such
failure.

     (b)  TAX FORMS.  Within thirty (30) days after the date of execution of
this Agreement, each Lender that is organized outside the United States agrees
that it will deliver to Murphy and Agents two (2) duly completed copies of
United States Internal Revenue Service Form 1001 (or such other documentation or
information as may, under applicable United States federal income tax statutes
or regulations, be required in order to claim an exemption or reduction from
United States income tax withholding by reason of an applicable treaty with the
United States, such documentation or other information being hereafter referred
to as "FORM 1001") or Form 4224 (or such other documentation or information as
may, under applicable United States federal income tax statutes or regulations,
be required in order to claim an exemption from United States income tax
withholding for income that is effectively connected with the conduct of a trade
or business within the United States, such documentation or other information
being hereafter referred to as "FORM 4224"), as the case may be, indicating in
each case that such Lender is either entitled to receive payments under this
Agreement without deduction or withholding of any United States federal income
taxes or, as the case may be, is subject to such limited deduction or
withholding as it is capable of recovering in full from a source other than
Borrower.  Each Lender which delivers to Murphy and Agents a Form 1001 or Form
4224 pursuant to the next preceding sentence further undertakes to deliver to
Murphy and Agents two (2) further copies of the said Form 1001 or 4224, or
successor applicable form or certificate, as the case may be, as and when the
previous form filed by it hereunder shall expire or shall become incomplete or
inaccurate in any respect, unless in any of such cases an event has occurred
prior to the date on which any such delivery would otherwise be required which
renders such form inapplicable.

     (c)  CREDITS.  If at any time any Lender by reason of payment by any
Borrower of any Withholding Taxes obtains a credit against, or return or
reduction of, any tax payable by it, or any other currently realized tax
benefit, which it would not have enjoyed but for such payment ("TAX BENEFIT"),
such Lender shall thereupon pay to such Borrower the amount which such Lender
shall certify to be the amount that, after payment, will leave such Lender in
the same economic position it would have been in had it received no such Tax
Benefit ("EQUALIZATION AMOUNT"); provided, however, that if such Lender shall
subsequently determine that it has lost the benefit of all or a portion of such
Tax Benefit, then such Borrower shall promptly remit to such Lender the amount
certified by such Lender to be the amount necessary to restore such Lender to
the position it would have been in if no payment had been made pursuant to this
SECTION 2.14(c); provided, further, however, that if such Lender shall be
prevented by applicable law from paying Borrower all or any portion of the
Equalization Amount owing to such Borrower, then such payment need not be made
to the extent such Lender is so prevented and the amount not paid shall be
credited to the extent lawful against future payment owing to such Lender;
provided, further, however, that the aggregate of all Equalization Amounts paid
by any Lender shall in no event exceed the aggregate of all amounts paid by such
Borrower to such Lender in respect of Withholding Taxes plus, in the case of a
Tax Benefit that occurs by reason of a refund, interest actually received from
the relevant taxing authority with respect to such refund. A certificate
submitted to the Applicable Agent and Murphy by such Lender pursuant to this
SECTION 2.14(c) shall be conclusive and binding for all purposes, absent
manifest error.

                                  Ex. 4.1-26
<PAGE>
 
     (d)  LENDING OFFICE.  In the event a Lender shall become aware that any
Borrower is required to pay any additional amount to it pursuant to SECTION
2.14(a), such Lender shall promptly notify Agents and Murphy of such fact and
shall use reasonable efforts, consistent with legal and regulatory restrictions,
to change the jurisdiction of its Applicable Lending Office if the making of
such change (i) would avoid the need for, or reduce the amount of, any such
additional amounts that may thereafter accrue, (ii) would not, in the good faith
determination of such Lender, be disadvantageous for regulatory or competitive
reasons to such Lender, and (iii) would not require such Lender to incur any
cost or forego any economic advantage for which such Borrower shall not have
agreed to reimburse and indemnify such Lender.

     (e)  EFFECT OF PARTICIPANTS.  Notwithstanding the foregoing provisions of
this SECTION 2.14, in the event any Lender grants a participation in any Advance
pursuant to SECTION 10.7, no Borrower shall be obligated to pay any taxes,
imposts, duties, charges, fees, deductions, or withholdings to the extent that
the aggregate amount thereof exceeds the aggregate amount for which such
Borrower would have been obligated if such Lender had not granted such
participation.

     2.15 SHARING OF PAYMENTS, ETC.  If any Lender shall obtain any payment
(whether voluntary, involuntary, through the exercise of any right of setoff, or
otherwise) on account of the Advances by it (other than pursuant to SECTIONS
2.10, 2.11, 2.14, or 10.4) in excess of its Applicable Commitment Percentage of
payments on account of the Advances or reimbursements on account of matured
Bankers' Acceptances obtained by all relevant Lenders, then such Lender shall
forthwith purchase from the other relevant Lenders through the Applicable Agent
such participations in the Advances made by them as shall be necessary to cause
such purchasing Lender to share the excess payment ratably with each of them,
such purchases to be made first of Advances in the same Type and currency as the
payment received by such Lender, and thereafter in such Types and currencies as
selected by such purchasing Lender; provided, however, that, if all or any
portion of such excess payment is thereafter recovered from such purchasing
Lender, then such purchase from each Lender shall be rescinded, and such Lender
shall repay to the purchasing Lender the purchase price to the extent of such
recovery, together with an amount equal to such Lender's ratable share
(according to the proportion that the (i) the amount of such Lender's required
repayment bears to (ii) 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. Borrowers agree that any Lender so
purchasing a participation from another Lender pursuant to this SECTION 2.15
may, to the fullest extent permitted by law, exercise all its rights of payment
(including the right of setoff) with respect to such participation as fully as
if such Lender were the direct creditor of the applicable Borrower in the amount
of such participation.

     2.16 BANKERS' ACCEPTANCES.

     (a)  CREATION.  Canadian Borrower may request pursuant to this SECTION
2.16, from time to time during the period from the date hereof to but excluding
the Termination Date, that each Canadian Lender create Bankers' Acceptances by
accepting Drafts from Canadian Borrower in an aggregate amount not exceeding
such Canadian Lender's Canadian Commitment Percentage of the aggregate Face
Amount of the Bankers' Acceptances to be created on any Drawing Date; provided
that Canadian Borrower shall not request the creation of any Bankers' Acceptance
if, after giving effect thereto, the Canadian Usage would exceed the Designated
Canadian Commitment then in effect.  Subject to the provisions of this SECTION
2.16 and the conditions precedent set forth in SECTION 3.2, each Canadian Lender
shall accept and purchase Bankers' Acceptances created by it as more
particularly specified in this SECTION 2.16 if such Bankers' Acceptances are not
purchased by a third party on the relevant Drawing Date.  The aggregate Face
Amount of the Bankers' Acceptances to be created on any Drawing Date shall be
equal to or greater than Cdn. $7,500,000.  If apportionment of Bankers'
Acceptances among all Lenders cannot be made on a ratable basis in even
multiples of Cdn.$100,000, then Administrative Agent shall round the allocations
among all Lenders up or down to the nearest Cdn.$100,000.

                                  Ex. 4.1-27
<PAGE>
 
     (b)  DRAWING NOTICE.  Bankers' Acceptances shall be created on not less
than two (2) Business Days' prior written notice given not later than 11:00 a.m.
(Toronto, Ontario time), by Canadian Borrower to Canadian Administrative Agent,
which shall give each Canadian Lender prompt notice thereof and of such Lender's
Canadian Commitment Percentage of the aggregate Face Amount of the Drafts to be
accepted (and purchased) by such Canadian Lender.  Each such notice (a "DRAWING
NOTICE") shall be in substantially the form of EXHIBIT G or by telephone
confirmed promptly in writing, containing the same information as would be
contained in a Drawing Notice, and shall specify (i) the Drawing Date, (ii) the
aggregate Face Amount of the Drafts to be accepted (and purchased), and (iii)
the maturity date for such Drafts (it being agreed and understood that Canadian
Borrower shall not be entitled to request a maturity date for Drafts which would
be subsequent to the Maturity Date).

     (c)  NOTICE IRREVOCABLE.  Neither Canadian Administrative Agent nor any
Canadian Lender shall incur any liability to Canadian Borrower in acting on any
telephonic notice referred to above that Canadian Administrative Agent believes
in good faith to have been given by a duly authorized officer or other person
authorized to borrow on behalf of Canadian Borrower or for otherwise acting in
good faith under this SECTION 2.16, and upon the creation and purchase of
Bankers' Acceptances pursuant to any such telephonic notice, Canadian Borrower
shall be liable with respect thereto as provided herein.  Each Drawing Notice
shall be irrevocable and binding on Canadian Borrower.  Canadian Borrower shall
indemnify each Canadian Lender against any loss or expense incurred by such
Canadian Lender as a result of any failure by Canadian Borrower to fulfill or
honor before the applicable Drawing Date the applicable conditions set forth in
this SECTION 2.16 or SECTION 3.2 if, as a result of such failure, the requested
Bankers' Acceptances are not created and/or purchased on such Drawing Date.

     (d)  DRAFTS.  Each Draft presented by Canadian Borrower shall: (i) be an
integral multiple of Cdn. $100,000; (ii) be dated the date of acceptance thereof
by the applicable Canadian Lender; (iii) mature and be payable by Canadian
Borrower on a Business Day which occurs 30, 60, 90, or, if available, 180 days
after the date thereof; (iv) be substantially in the form of EXHIBIT D; and (iv)
be otherwise consistent with the provisions of this Agreement relating to the
amounts and maturity dates thereof.  The acceptance endorsed by Canadian Lender
on any Draft shall be substantially in the form as may be agreed by Canadian
Borrower and such Canadian Lender.

     (e)  ACCEPTANCE OF DRAFTS.  Not later than 11:00 a.m. (Toronto, Ontario
time) on an applicable Drawing Date, each Canadian Lender shall complete Drafts,
dated such Drawing Date, with the maturity date and denominations specified in
the applicable Drawing Notice, and following fulfillment of the applicable
conditions as set forth in SECTION 3.2 and as specified in the applicable
Drawing Notice, shall accept such Drafts and purchase the Bankers' Acceptances
thereby created for the applicable Bankers' Acceptance Purchase Price.  Canadian
Borrower hereby authorizes each Canadian Lender to deduct from the amount to be
remitted by it to Canadian Administrative Agent in respect of the Bankers'
Acceptance Purchase Price of any Bankers' Acceptance created by it the BA Fee in
respect of such Bankers' Acceptance.  The failure of any Canadian Lender to
create and purchase or deliver Bankers' Acceptances shall not relieve such
Canadian Lender of its obligation, if any, to create and purchase or deliver
Bankers' Acceptances hereunder, but a Canadian Lender shall not be responsible
for the failure of any other Canadian Lender to create and purchase or deliver
Bankers' Acceptances on any Drawing Date.

     (f)  FUNDING.  Subject to this SECTION 2.16, each Canadian Lender shall,
(i) before 12:00 noon (Toronto time) on the applicable Drawing Date in the case
of the Bankers' Acceptance Purchase Price for each Bankers' Acceptance purchased
by it, or (ii) upon receipt by it on the applicable Drawing Date of the purchase
price payable by a third party in respect of any Bankers' Acceptance created by
it and purchased by such third party, make available to Canadian Administrative
Agent at its address referred to in SECTION 10.2, in same day funds, such amount
(less the applicable BA Fee as aforesaid).  Upon Canadian Administrative Agent's
receipt of such funds and upon fulfillment of the applicable conditions set
forth in SECTION 3.2, 

                                  Ex. 4.1-28
<PAGE>
 
Canadian Administrative Agent will make such funds available to Canadian
Borrower at Canadian Administrative Agent's aforesaid address.

     (g)  HOLDING OF BANKERS' ACCEPTANCES.  Bankers' Acceptances purchased by a
Canadian Lender hereunder may be held by it for its own account until maturity
or sold by it at any time prior thereto in any relevant market therefor in
Canada, in such Canadian Lender's sole discretion.

     (h)  REPAYMENT.

           (i)   REFUNDING.  So long as no Potential Default or Event of Default
     exists, Canadian Borrower may give irrevocable telephonic (followed by
     written confirmation electronically transmitted to Canadian Administrative
     Agent on the same day) or written notice (or such other method of
     notification as may be agreed to by Canadian Administrative Agent and
     Canadian Borrower) to Canadian Administrative Agent at or before 11:00 a.m.
     (Toronto, Ontario time) two (2) Business Days prior to the maturity date of
     any Bankers' Acceptance of Canadian Borrower's intention to issue one or
     more Bankers' Acceptances on such maturity date (each a "REFUNDING BANKERS'
     ACCEPTANCE") to provide for the payment of such maturing Bankers'
     Acceptance (it being understood that the payment by Canadian Borrower and
     fundings by Canadian Lenders in respect of each maturing Bankers'
     Acceptance and each related Refunding Bankers' Acceptance shall be made on
     a net basis reflecting the difference between the face amount of such
     maturing Bankers' Acceptance and the Bankers' Acceptance Purchase Price
     (less the applicable BA Fee) of such Refunding Bankers' Acceptance).

           (ii)  REPAYMENT.  Canadian Borrower shall pay to Canadian
     Administrative Agent, for the account of the applicable Canadian Lender,
     and there shall become due and payable, at 12:00 noon (Toronto, Ontario
     time) on the maturity date for each Bankers' Acceptance, an amount in
     Canadian Dollars in same day funds equal to the Face Amount of such
     Bankers' Acceptance.  The obligation of Canadian Borrower to make such
     payment shall not be prejudiced by the fact that the holder of any such
     Bankers' Acceptance is the Canadian Lender that accepted such Bankers'
     Acceptance.  Canadian Borrower hereby renounces, and shall not claim, any
     days of grace for the payment of any Bankers' Acceptances.  Bankers'
     Acceptances may not be prepaid.

           (iii) FAILURE TO REPAY.  If Canadian Borrower fails to pay to
     Canadian Administrative Agent, for the account of the applicable Canadian
     Lender, the Face Amount of any Bankers' Acceptance as required by the
     preceding paragraph, then Canadian Borrower shall be deemed to have given a
     Notice of Borrowing to Canadian Administrative Agent requesting that such
     Canadian Lender make a Canadian Dollar Base Rate Advance on the date that
     such payment is due and payable, and thereupon such Lender shall, subject
     to the fulfillment of the applicable conditions set forth in SECTION 3.2,
     as of such date, make such Canadian Dollar Base Rate Advance to Canadian
     Borrower, the proceeds of which shall be applied directly to reimburse such
     Canadian Lender for the Face Amount of such Bankers' Acceptance paid by it.
     Canadian Administrative Agent will give to Canadian Borrower notice of any
     such action promptly after any such action; provided, however, that the
     failure to give such notice shall not limit or otherwise affect the
     obligations of Canadian Borrower under this Agreement or any other Loan
     Document.

     (i)  NUMBER OF DRAFTS.  To enable Canadian Lenders to complete Drafts and
create and purchase Bankers' Acceptances in the manner specified in this SECTION
2.16, Canadian Borrower shall supply each Canadian Lender with such number of
Drafts as such Canadian Lender may reasonably request, duly endorsed and
executed on behalf of Canadian Borrower.  Each Canadian Lender shall exercise
such care in the custody and safekeeping of Drafts as it would exercise in the
custody and safekeeping of similar property 

                                  Ex. 4.1-29
<PAGE>
 
owned by it. Each Canadian Lender will, upon request by Canadian Borrower,
promptly advise Canadian Borrower of the number and designations, if any, of the
Drafts then held by it. The signatures of any officers of Canadian Borrower may
be mechanically reproduced in facsimile, and Drafts and Bankers' Acceptances
bearing such facsimile signatures shall be binding upon Canadian Borrower as if
they had been manually signed by such officers. Notwithstanding that any of the
individuals whose manual or facsimile signature appears on any Draft or Bankers'
Acceptance as one of such officers may no longer hold office at the date thereof
or at the date of its acceptance by a Canadian Lender hereunder or at any time
thereafter, any Draft or Bankers' Acceptance so signed shall be valid and
binding upon Canadian Borrower.

     (j)  LIMITATION ON BANKERS' ACCEPTANCES.  If Canadian Administrative Agent
determines in good faith, which determination shall be final, conclusive, and
binding upon Borrowers, and notifies Murphy and each Canadian Lender that, by
reason of circumstances affecting the money market (i) there is no market for
Bankers' Acceptances, or (ii) the demand for Bankers' Acceptances is
insufficient to allow the sale or trading of the Bankers' Acceptances created
and purchased hereunder; then:

          (i)  the right of Canadian Borrower to request that Bankers'
     Acceptances be created hereunder shall be suspended until Canadian
     Administrative Agent determines that the circumstances causing such
     suspension no longer exist and Canadian Administrative Agent so notifies
     Murphy; and

          (ii) any Drawing Notice which is outstanding shall be canceled and the
     Bankers' Acceptances requested therein shall not be created.

     (k)  COLLATERAL ACCOUNT.  Canadian Borrower agrees that, if the Obligation
is accelerated pursuant to SECTION 7.2, then if requested by Canadian
Administrative Agent or by the Required Lenders (through any Agent), it will pay
to Canadian Administrative Agent an amount in immediately available funds equal
to the BA Usage, which funds shall be held by Canadian Administrative Agent in
an interest bearing collateral account and are hereby collaterally assigned to
Canadian Administrative Agent, for the ratable benefit of Canadian Lenders until
the BA Usage shall have been fully satisfied or no Event of Default exists, at
which time all funds in such collateral account (including all interest on
amounts held therein) shall be released to Canadian Borrower.

                                  SECTION 3.

                       CONDITIONS OF CLOSING AND LENDING

     3.1  CONDITIONS PRECEDENT TO CLOSING.  The obligation of each Lender to
execute and deliver this Agreement and the other Loan Documents is subject to
the conditions precedent that Domestic Administrative Agent shall have received,
on or before the date hereof (unless otherwise indicated), the following, each
dated the same day (unless otherwise indicated), in form and substance
satisfactory to Domestic Administrative Agent and in sufficient copies for each
Lender:

     (a)  Receipt by Domestic Administrative Agent of a Certificate of the

                        REPRESENTATIONS AND WARRANTIES

     To induce Lenders to enter into this Agreement, Borrowers represent and
warrant as of the date hereof (except for SECTIONS 4.1, 4.2, 4.3, and 4.4, which
are as of the date hereof and as of the date of each Advance hereunder) to
Agents and Lenders as follows:

     4.1  EXISTENCE; QUALIFICATION.  Each Company is duly organized, validly
existing, and in good standing under the laws of the jurisdiction of its
incorporation, formation, or organization.  Each Company is duly qualified to do
business in each jurisdiction in which any such failure to so qualify could be a
Material Adverse Event.

     4.2  POWER.  The execution, delivery, and performance by each Borrower of
this Agreement and the other Loan Documents to which such Borrower is a party
are within such Borrower's corporate powers, have been duly authorized by all
necessary corporate action, and do not contravene (a) any Borrower's Constituent
Documents, or (b) any Legal Requirement or contractual restriction binding on or
affecting any Borrower.

                                  Ex. 4.1-31
<PAGE>
 
     4.3  AUTHORIZATIONS.  No Authorization or other action by, and no notice to
or filing with, any Governmental Authority or other Person is required for the
due execution, delivery, and performance by Borrowers of this Agreement and the
other Loan Documents, except for such Authorizations that have been duly
obtained or made and that are in full force and effect.

     4.4  ENFORCEABILITY.  This Agreement and the other Loan Documents are the
legal, valid, and binding obligation of each Borrower enforceable against each
Borrower in accordance with their respective terms.

     4.5  FINANCIAL INFORMATION.  The consolidated financial statements of
Murphy dated as of June 30, 1997, are complete and correct and fairly present
the financial condition of Murphy, on a consolidated basis, as of said date and
the results of operations and cash flows of Murphy, on a consolidated basis, for
the stated periods then-ended, all in accordance with GAAP.  As of the date
hereof, no Material Adverse Event has occurred since June 30, 1997, and no
Company has any material direct or contingent liabilities which are not
disclosed by or reserved against in the financial statements referred to above
or otherwise disclosed in writing to Domestic Administrative Agent.

     4.6  LITIGATION, JUDGMENTS, ETC.  No Company is subject to, or aware of the
threat of, any Litigation which is reasonably likely to be determined adversely
to any Company, and, if so adversely determined, could (individually or
collectively with other Litigation) be a Material Adverse Event.  There are no
outstanding orders or judgments for the payment of money in excess of
$35,000,000 (individually or collectively) or any warrant of attachment,
sequestration, or similar proceeding against any Company's assets having a value
(individually or collectively) of $35,000,000 or more which is not either (a)
stayed on appeal, or (b) being diligently contested in good faith by appropriate
proceedings and adequate reserves have been set aside on the books of such
Company in accordance with GAAP.  There are no formal complaints, suits, claims,
investigations, or proceedings initiated at or by any Governmental Authority
pending or, to any Borrower's knowledge, threatened by or against any Company
which could be a Material Adverse Event, nor any judgments, decrees, or orders
of any Governmental Authority outstanding against any Company that could be a
Material Adverse Event.

     4.7  REGULATION U.

     (a)  After applying the proceeds of each Advance, not more than twenty-five
percent (25%) of the value of the assets of Murphy, on a consolidated basis, (as
determined in good faith by Murphy) that are subject to SECTION 6.1 or 6.2 will
consist of or be represented by margin stock (within the meaning of Regulation U
issued by the Board of Governors of the Federal Reserve System).

     (b)  No Borrower is engaged in the business of extending credit for the
purpose of purchasing or carrying margin stock (within the meaning of Regulation
U issued by the Board of Governors of the Federal Reserve System), and no
proceeds of any Advance will be used for any purpose which violates the
provisions of the regulations of said Board.  If requested by Domestic
Administrative Agent or any Lender, Borrowers will furnish to Domestic
Administrative Agent and each Lender a statement in conformity with the
requirements of Federal Reserve Form U-1 referred to in Regulation U, the
statements made in which shall be such, in the opinion of each Lender, as to
permit the transactions contemplated hereby in accordance with Regulation U.

     4.8  ERISA.  No Termination Event has occurred nor is reasonably expected
to occur with respect to any Material Plan.  No Company or any ERISA Affiliate
has incurred nor reasonably expects to incur any withdrawal liability under
ERISA or any Applicable Canadian Pension Legislation to any Multi-employer Plan
which could be a Material Adverse Event.  Schedule B (Actuarial Information) to
the 1996 annual report (Form 5500 Series) with respect to each Plan, copies of
which have been filed with the Internal Revenue Service and furnished to
Domestic Administrative Agent, is complete and accurate in all material

Plan as of the date of such schedule.

     4.9  TAXES.  All tax returns of each Company required to be filed have been
filed (or extensions have been granted) prior to delinquency, except for any
such returns for which the failure to so file could not be a Material Adverse
Event, and all Taxes imposed upon each Company which are due and payable have
been paid prior to delinquency, other than Taxes for which non-payment thereof
could not be a Material Adverse Event.  The charges, accruals, and reserves on
the books of the Companies in respect of Taxes or other governmental charges
are, in the opinion of Borrowers, adequate.

     4.10 ENVIRONMENTAL MATTERS.  No (a) environmental condition or
circumstance, such as the presence or release of any Hazardous Substance, exists
on any property presently or previously owned by any Company that could be a
Material Adverse Event, (b) violation by any Company of any Environmental Law
has occurred, except for such violations that could not be a Material Adverse
Event, or (c) Company is under any obligation to remedy any violation of any
Environmental Law, except for such obligations that could not be a Material
Adverse Event.  Each Company has (i) in full force and effect all environmental
permits, licenses, and approvals required to conduct its operations and is

determine that its properties and operations are not in violation of any
Environmental Law.

title to or valid leasehold interests in their respective material properties
and assets, real and personal, including the properties, assets, and leasehold
interests reflected in the financial statements described in SECTION 4.5, and

is subject to any Lien, except as permitted by SECTION 6.1.

transactions contemplated by the Loan Documents), each Borrower is Solvent.

     4.13 FULL DISCLOSURE.  There is no material fact or condition relating to
the Loan Documents or the financial condition, business, or property of any
Company which could be a Material Adverse Event and which has not been related,
in writing, to Domestic Administrative Agent.  All information heretofore

Documents was, and all such information hereafter furnished by any Company to
any Lender or any Agent will be, true, correct, and complete in all material
respects or based on reasonable estimates on the date as of which such
information is stated or certified.

     4.14 NO POTENTIAL DEFAULT.  No event has occurred and is continuing which
constitutes a Potential Default or an Event of Default.

statements, representations, or warranties contained in this Agreement, any
other Loan Document, or in any certificate or other document referred to or
provided for in, or received by any of them under, this Agreement or any other
Loan Document, or for the value, validity, effectiveness, genuineness,
execution, effectiveness, legality, enforceability, or sufficiency of this
Agreement or any other Loan Document, or any other document referred to or
provided for herein or for any failure by any Borrower or any other Person
(other than such Agent) to perform any of its obligations hereunder or
thereunder or for the existence, value, perfection, or priority of any
collateral security, or the financial or other condition of any Borrower or any
other obligor or guarantor; (c) except pursuant to SECTION 8.7, shall not be
required to initiate or conduct any litigation or collection proceedings
hereunder; and (d) shall not be responsible for any action taken or omitted to
be taken by it hereunder or under any other Loan Document, including its own
ordinary negligence, except for its own gross negligence or willful misconduct.
Each Agent may employ agents, accountants, attorneys, and experts and shall not
be responsible for the negligence or misconduct of any such agents, accountants,
attorneys, or experts selected by it in good faith or any action taken or
omitted to be taken in good faith by it in accordance with the advice of such
agents, accountants, attorneys, or experts.  Each Agent may deem and treat the
payee of any Advance as the holder thereof for all purposes hereof unless and
until a written notice of the assignment or transfer thereof permitted hereunder
shall have been filed with Domestic Administrative Agent (who shall provide
notice to Canadian Administrative Agent).

     8.2  RELIANCE BY AGENTS.  Each Agent shall be entitled to rely upon any
certification, notice, or other communication (including any thereof by
telephone, telex, telecopier, telegram, or cable) believed by it to be genuine
and correct and to have been signed or sent by or on behalf of the proper Person
or Persons, and upon advice and statements of legal counsel, independent
accountants, and other experts selected by such Agent.

     8.3  NOTICES; DEFAULTS.  Each Agent agrees to give the other Agent and each
Lender prompt notice of each notice and a copy of each document, certificate, or
instrument given to such Agent by each Borrower pursuant to this Agreement or
the other Loan Documents.  No Agent shall be deemed to have knowledge of the
occurrence of any Potential Default or any Event of Default (other than such
Agent's notice of the non-payment of principal of, or interest on, the
Obligation or of fees).  In the event that any Agent receives a notice of the
occurrence of a Potential Default or an Event of Default specifying such
Potential Default or Event of Default and stating that such notice is a "Notice
of Default," such Agent shall give prompt notice thereof to the other Agent and
Lenders.  In the event of a payment default, each Agent shall give each Lender
prompt notice of each such payment default.

     8.4  RIGHTS AS A LENDER.

     (a)  AGENTS AS LENDERS.  With respect to its Commitments and the Advances
made by it, each Agent (and any successor acting as an Agent) in its capacity as
a Lender hereunder shall have the same rights and powers hereunder as any other
Lender and may exercise the same as though it were not acting as an Agent, and
the term "Lender" or "Lenders" shall, unless the context otherwise indicates,
include each Agent in its individual capacity.

     (b)  OTHER ACTIVITIES.  Each Agent (and any successor acting as an Agent)
and its Affiliates may (without having to account therefor to any Lender) accept
deposits from, lend money to, and generally engage in any kind of banking,
trust, or other business with any Borrower (and any of their Affiliates) as if
it were not acting as an Agent, and each Agent and its Affiliates may accept
fees and other consideration from any Borrower for services in connection with
this Agreement or otherwise without having to account for the same to Lenders.
Each Agent may now or hereafter be engaged in one or more loan, letter of
credit, leasing, or other financing transactions with any Borrower, act as
trustee or depository for any Borrower, or otherwise be engaged in other
transactions with any Borrower (collectively, the "OTHER ACTIVITIES") not the
subject of the Loan Documents.  Without limiting the rights of Lenders
specifically set forth in the Loan Documents, no Agent shall be responsible to
account to Lenders for such Other Activities, and no Lender shall have any

                                  Ex. 4.1-39
<PAGE>
 
interest in any Other Activities, any present or future guaranties by or for the
account of any Borrower which are not contemplated or included in the Loan
Documents, any present or future offset executed by any Agent in respect of such
Other Activities, any present or future property taken as security for any such
Other Activities, or any property now or hereafter in the possession or control
of any Agent which may be or become security for the obligations of any Borrower
arising under the Loan Documents by reason of the general description of debt
secured or of property contained in any other agreements, documents, or
instruments relating to any such Other Activities; provided that if any payments
in respect of such guaranties or such property or the proceeds thereof shall be
applied to the reduction of the obligations of any Borrower arising under the
Loan Documents, then each Lender shall be entitled to share in such application
ratably.

     8.5 INDEMNIFICATION. EACH LENDER AGREES TO INDEMNIFY EACH AGENT AND EACH OF
ITS AFFILIATES, OFFICERS, DIRECTORS, EMPLOYEES, REPRESENTATIVES, AGENTS,
ATTORNEYS, ACCOUNTANTS, AND EXPERTS (THE "AGENT PARTIES"), RATABLY IN ACCORDANCE
WITH SUCH LENDER'S PERCENTAGE SHARE FOR THE INDEMNITY MATTERS AS DESCRIBED IN
SECTION 10.15 TO THE EXTENT NOT INDEMNIFIED OR REIMBURSED BY BORROWERS AS
REQUIRED UNDER SECTION 10.15, (BUT WITHOUT LIMITING THE OBLIGATIONS OF BORROWERS
UNDER SECTION 10.15) AND FOR ANY AND ALL OTHER LIABILITIES, OBLIGATIONS, LOSSES,
DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES, OR DISBURSEMENTS
OF ANY KIND AND NATURE WHATSOEVER WHICH MAY BE IMPOSED ON, INCURRED BY, OR
ASSERTED AGAINST ANY AGENT PARTY IN ANY WAY RELATING TO OR ARISING OUT OF THIS
AGREEMENT, THE OTHER LOAN DOCUMENTS, OR ANY OTHER DOCUMENTS CONTEMPLATED BY OR
REFERRED TO HEREIN OR THEREIN OR THE TRANSACTIONS CONTEMPLATED HEREBY OR
THEREBY; PROVIDED THAT NO LENDER SHALL BE LIABLE FOR ANY OF THE FOREGOING TO THE
EXTENT THEY ARISE FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF ANY AGENT
PARTY.

     8.6  NON-RELIANCE ON AGENTS AND OTHER LENDERS.  Each Lender acknowledges
and agrees that it has, independently and without reliance on any Agent (or any
Agent's Affiliates, officers, directors, employees, attorneys, accountants,
experts, representatives, or agents) or any other Lender, and based on such
documents and information as it has deemed appropriate, made its own credit
analysis of Borrowers and its decision to enter into this Agreement, and that it
shall, independently and without reliance upon any 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 analysis and decisions in taking or not taking
action under this Agreement.  No Agent shall be required to keep itself informed
as to the performance or observance by Borrowers of this Agreement, the other
Loan Documents, or any other document referred to or provided for herein or to
inspect the properties or books of Borrowers.  Except for notices, reports, and
other documents and information expressly required to be furnished to Lenders by
an Agent hereunder or provided to an Agent with copies for Lenders, no Agent
shall have any duty or responsibility to provide any Lender with any credit or
other information concerning the affairs, financial condition, or business of
Borrowers (or any of their Affiliates) which may come into the possession of any
Agent or any of its Affiliates.

     8.7  ACTION BY AGENTS.  Except for action or other matters expressly
required of an Agent hereunder, each Agent shall in all cases be fully justified
in failing or refusing to act hereunder unless it shall (a) receive written
instructions from Required Lenders (or if this Agreement requires, all Lenders)
specifying the action to be taken, and (b) be indemnified to its satisfaction by
Lenders against any and all liability and expenses which may be incurred by it
by reason of taking or continuing to take any such action, except for such
Agent's gross negligence or willful misconduct.  The instructions of Required
Lenders (or if this Agreement requires, all Lenders) and any action taken or
failure to act pursuant thereto by any Agent shall be binding on all Lenders.
If an Event of Default exists, then each Agent shall take such action with
respect to such Event of Default as shall be directed by Required Lenders (or if
this Agreement requires, all Lenders) in the written instructions (with
indemnities) described in this SECTION 8.7; provided that, unless and until an
Agent shall have received such directions, such Agent may (but shall not be
obligated to) take such action, or refrain from taking such action, with respect
to such Event of Default as it shall deem advisable in the best interests of
Lenders.  In no event, however, shall any Agent be required to take any action
which exposes such 

                                  Ex. 4.1-40
<PAGE>
 
Agent to personal liability or which is contrary to this Agreement and the other
Loan Documents or applicable law.

     8.8  RESIGNATION OR REMOVAL OF AGENTS.  Subject to the appointment and
acceptance of a successor as provided below, each Agent may resign at any time
by giving notice thereof to Lenders and Murphy, and any Agent may be removed at
any time with cause by Required Lenders.  Upon any such resignation or removal,
Required Lenders shall have the right to appoint a successor Agent.  If no
successor Agent shall have been so appointed by Required Lenders and shall have
accepted such appointment within thirty (30) days after the retiring Agent's
giving of notice of resignation or Required Lenders' removal of the retiring
Agent, then the retiring Agent may, on behalf of Lenders, appoint a respective
successor Administrative Agent.  Upon the acceptance of such appointment
hereunder by a successor Agent, such successor Agent shall thereupon succeed to
and become vested with all the rights, powers, privileges, and duties of the
retiring Agent, and the retiring Agent shall be discharged from its duties and
obligations hereunder.  After any retiring Agent's resignation or removal
hereunder as an Agent, the provisions of this SECTION 8 and SECTION 10.4 shall
continue in effect for its benefit in respect of any actions taken or omitted to
be taken by it while it was acting as an Agent.

     8.9  RELATIONSHIP OF LENDERS.  Nothing herein shall be construed as
creating a partnership or joint venture among any Agent and any Lender or among
any Agent or Lenders.

     8.10 BENEFITS OF AGREEMENT.  None of the provisions of this SECTION 8 shall
inure to the benefit of any Borrower or any other Person other than Agents and
Lenders; consequently, no Borrower nor any other Person shall be entitled to
rely upon, or to raise as a defense, in any manner whatsoever, the failure of
any Lender to comply with such provisions.

                                  SECTION 9.

                              GUARANTY AGREEMENT

     9.1  GUARANTY OF OBLIGATION.  Murphy hereby irrevocably and unconditionally
guarantees to Agents and Lenders and their respective successors and permitted
assigns the due and punctual payment and performance of the Guaranteed Debt.
Murphy hereby irrevocably and unconditionally covenants and agrees that it is
liable for the Guaranteed Debt as primary obligor.  The agreement of Murphy in
this SECTION 9 (the "GUARANTY AGREEMENT") is intended to be an irrevocable,
absolute, continuing guaranty of payment and is not a guaranty of collection.
This Guaranty Agreement may not be revoked by Murphy.  This Guaranty Agreement
may be enforced by any Agent or any Lender and any subsequent holder of the
Guaranteed Debt and shall not be discharged by the assignment or negotiation of
all or part of the Guaranteed Debt.

     9.2  GUARANTEED DEBT NOT REDUCED BY OFFSET.  The Guaranteed Debt and the
liabilities and obligations of Murphy to Agents and Lenders hereunder, shall not
be reduced, discharged, or released because or by reason of any existing or
future offset, claim, or defense of any Subsidiary Borrower, or any other party,
against any Agent or any Lender, or against payment of the Guaranteed Debt,
whether such offset, claim, or defense arises in connection with the Guaranteed
Debt (or the transactions creating the Guaranteed Debt) or otherwise.  Without
limiting the foregoing or Murphy's liability hereunder, to the extent that any
Agent or any Lender advances funds or extends credit to any Subsidiary Borrower,
and does not receive payments or benefits thereon in the amounts and at the
times required or provided by applicable agreements or laws, Murphy is
absolutely liable to make such payments to (and confer such benefits on) Agents
and Lenders on a timely basis.

                                  Ex. 4.1-41
<PAGE>
 
     9.3  PAYMENT BY MURPHY.  If all or any part of the Guaranteed Debt shall
not be punctually paid when due, whether at maturity or earlier by acceleration
or otherwise, Murphy shall, immediately upon demand by the Applicable Agent, and
without presentment, protest, notice of protest, notice of nonpayment, notice of
intention to accelerate or acceleration, or any other notice whatsoever, pay in
the Applicable Currency, the amount due on the Guaranteed Debt to the Applicable
Agent, for the benefit of the Applicable Agent and Lenders.

     9.4  NO DUTY TO PURSUE OTHERS.  It shall not be necessary for any Agent or
any Lender (and Murphy hereby waives any rights which Murphy may have to require
any Agent or any Lender), in order to enforce such payment by Murphy, first to
(a) institute suit or exhaust its remedies against any Subsidiary Borrower or
others liable on the Guaranteed Debt or any other Person, (b) join any
Subsidiary Borrower or any others liable on the Guaranteed Debt in any action
seeking to enforce this Guaranty Agreement, or (c) resort to any other means of
obtaining payment of the Guaranteed Debt.

     9.5  WAIVER OF NOTICES, ETC.  Murphy hereby waives notice of (a) any
Advance or other loans made by any Agent or any Lender to any Subsidiary
Borrower, (b) acceptance of this Guaranty Agreement, (c) the execution and
delivery by any Subsidiary Borrower and any Agent or any Lender of any other
loan or credit agreement or of any Subsidiary Borrower's execution and delivery
of any promissory notes or other documents in connection therewith, (d) except
for notices required in SECTION 10.7, any Lender's assignment of or granting of
a participation in the Guaranteed Debt, or any part thereof, (e) any protest,
proof of nonpayment, or default by any Subsidiary Borrower, or (f) any other
action at any time taken or omitted by any Agent or any Lender, and, generally,
all demands and notices of every kind in connection with this Guaranty
Agreement, this Agreement, and any other Loan Documents and the obligations
hereby guaranteed.

     9.6  EFFECT OF BANKRUPTCY; OTHER MATTERS.  If, pursuant to any Debtor
Relief Law, or any judgment, order, or decision thereunder, or for any other
reason, (a) any Agent or any Lender must rescind or restore any payment, or any
part thereof, received by such Agent or such Lender in satisfaction of the
Guaranteed Debt, as set forth herein, any prior release or discharge from the
terms of this Guaranty Agreement given to Murphy by such Agent or such Lender
shall be without effect, and this Guaranty Agreement shall remain in full force
and effect, or (b) any Subsidiary Borrower shall cease to be liable to any Agent
or any Lender for any of the Guaranteed Debt (other than by reason of the
indefeasible payment in full thereof by such Subsidiary Borrower), then the
obligations of Murphy under this Guaranty Agreement shall remain in full force
and effect.  It is the intention of Agents, Lenders, and Murphy that Murphy's
obligations hereunder shall not be discharged except by Murphy's performance of
such obligations and then only to the extent of such performance.  Without
limiting the generality of the foregoing, it is the intention of Agents, Lenders
and Murphy that the filing under any Debtor Relief Law by or against any
Subsidiary Borrower or any other person or party obligated on any portion of the
Guaranteed Debt shall not affect the obligations of Murphy under this Guaranty
Agreement or the rights of any Agent or any Lender under this Guaranty
Agreement, including, without limitation, the right or ability of any Agent or
any Lender to pursue or institute suit against Murphy for the entire Guaranteed
Debt.

     9.7  ADDITIONAL EVENTS AND CIRCUMSTANCES NOT REDUCING OR DISCHARGING
MURPHY'S OBLIGATIONS.  Murphy hereby consents and agrees to each of the
following, and agrees that Murphy's obligations under this Guaranty Agreement
shall not be released, diminished, impaired, reduced, or adversely affected by
any of the following, and waives any common law, equitable, statutory, or other
rights (including without limitation rights to notice) which Murphy might
otherwise have as a result of or in connection with any of the following: (a)
any renewal, waiver, or amendment of all or any part of the Guaranteed Debt,
this Agreement, or the other Loan Documents; (b) any adjustment, indulgence,
forbearance, or compromise that might be granted or given by any Agent or any
Lender to any Subsidiary 

                                  Ex. 4.1-42
<PAGE>
 
Borrower or Murphy; (c) the insolvency, bankruptcy, arrangement, adjustment,
composition, structure, liquidation, disability, dissolution, or lack of power
of any Subsidiary Borrower under any Debtor Relief Law; (d) any dissolution of
any Subsidiary Borrower or Murphy, or any sale, lease, or transfer of any or all
of the assets of any Subsidiary Borrower or Murphy, or any changes in name,
business, location, composition, structure, or changes in the shareholders,
partners, or members (whether by accession, secession, cessation, death,
dissolution, transfer of assets, or other matter) of any Subsidiary Borrower or
Murphy; (e) the invalidity, illegality, or unenforceability of all or any part
of the Guaranteed Debt or Loan Document, for any reason whatsoever; (f) any full
or partial release of the liability of any Subsidiary Borrower on the Guaranteed
Debt or any part thereof, or Murphy or any other person or entity now or
hereafter liable, whether directly or indirectly, jointly, severally, or jointly
and severally, to pay, perform, guarantee, or assure the payment of the
Guaranteed Debt or any part thereof; (g) the failure of any Agent or any Lender
to exercise diligence or reasonable care or act, fail to act or comply with any
duty in the administration, preservation, enforcement, or other handling or
treatment of all or any part of Guaranteed Debt; (h) any existing or future
right of offset, claim, or defense of any Subsidiary Borrower against any Agent
or any Lender, or any other party, or against payment of the Guaranteed Debt,
whether such right of offset, claim, or defense arises in connection with the
Guaranteed Debt (or the transactions creating the Guaranteed Debt) or otherwise;
(i) the reorganization, merger, or consolidation of any Subsidiary Borrower or
Murphy into or with any other corporation or entity; or (j) any payment by any
Subsidiary Borrower to any Agent or any Lender is held to constitute a
preference under any Debtor Relief Laws, or for any reason any Agent or any
Lender is required to refund such payment or pay such amount to such Subsidiary
Borrower or someone else.

     9.8    SUBORDINATION OF GUARANTOR CLAIMS.  As used herein, the term
"GUARANTOR CLAIMS" shall mean all debts and liabilities of each Subsidiary
Borrower to Murphy, whether such debts and liabilities now exist or are
hereafter incurred or arise, or whether the obligations of any Subsidiary
Borrower thereon be direct, contingent, primary, secondary, several, joint and
several, or otherwise, and irrespective of whether such debts or liabilities be
evidenced by note, contract, open account, or otherwise, and irrespective of the
person or persons in whose favor such debts or liabilities may, at their
inception, have been, or may hereafter be created, or the manner in which they
have been or may hereafter be acquired by Murphy.  Guarantor Claims shall
include, without limitation, all rights and claims of Murphy against each
Subsidiary Borrower (arising as a result of subrogation or otherwise) as a
result of Murphy's payment of all or a portion of the Guaranteed Debt.  Until
the Guaranteed Debt shall be paid and satisfied in full and Murphy shall have
performed all of its obligations hereunder, Murphy shall not receive or collect,
directly or indirectly, from any Subsidiary Borrower or any other party any
amount upon Guarantor Claims.  In the event that, notwithstanding the terms of
this Guaranty Agreement, Murphy should receive any funds, payment, claim, or
distribution which is prohibited by this Guaranty Agreement, Murphy agrees to
hold in trust for Agents and Lenders, in kind, all funds, payments, claims, or
distributions so received, and agrees that it shall have absolutely no dominion
over such funds, payments, claims, or distributions so received except to pay
them promptly to Domestic Administrative Agent, for the benefit of Agents and
Lenders, and Murphy covenants promptly to pay the same to Domestic
Administrative Agent, for the benefit of Agents and Lenders.

     9.9    CLAIMS IN BANKRUPTCY.  In the event of receivership, bankruptcy,
reorganization, arrangement, debtor's relief, or other insolvency proceedings
under any Debtor Relief Law involving any Subsidiary Borrower as debtor, Agents
and Lenders shall have the right to prove its claim in any such proceeding so as
to establish its rights hereunder and receive directly from the receiver,
trustee, or other court custodian dividends and payments which would otherwise
be payable upon Guarantor Claims.  Murphy hereby assigns such dividends and
payments to Agents and Lenders.  Should any Agent or any Lender receive, for
application upon the Guaranteed Debt, any such dividend or payment which is
otherwise payable to Murphy, and which, as between any Subsidiary Borrower and
Murphy, shall constitute a credit upon Guarantor Claims, then upon payment to
Agents and Lenders in full of the Guaranteed Debt, Murphy shall become
subrogated to the rights of Agents and Lenders to the extent that such payments
to Agents and Lenders on Guarantor Claims have contributed toward the
liquidation of the Guaranteed Debt, and such subrogation shall be with respect
to that proportion of the Guaranteed Debt which would have been unpaid if Agents
and Lenders had not received dividends or payments upon Guarantor Claims.

<PAGE>
 
     9.10   WITHHOLDING TAXES.  All payments made or to be made by Murphy under
this Guaranty Agreement shall be made free and clear of, and without reduction
for or on account of, any Withholding Taxes.  If any Withholding Taxes are
required to be withheld from any amount payable to or for the account of any
Agent or any Lender under this Guaranty Agreement, including any further amount
payable by Murphy pursuant to this SECTION 9.10, then the amount so payable to
or for the account of the Applicable Agent or the Applicable Lender shall be
increased to the extent necessary to yield to the Applicable Agent or the
Applicable Lender (after payment of all Withholding Taxes including Withholding
Taxes on all such additional amounts) the full amount payable to or for the
account of the Applicable Agent or the Applicable Lender under this Guaranty
Agreement. Whenever any Withholding Tax is payable by Murphy, as promptly as
possible thereafter Murphy shall send to Domestic Administrative Agent, for the
account of the Applicable Agent or the Applicable Lender, a certified copy of an
original official receipt showing payment thereof.  If Murphy fails to pay any
Withholding Taxes when due to the appropriate taxing authority or fails to remit
to the Domestic Administrative Agent the required receipts or other required
documentary evidence, then Murphy shall indemnify the Applicable Agent or the
Applicable Lender for any incremental taxes, interest, or penalties that may
become payable by the Applicable Agent or the Applicable Lender as a result of
any such failure.  The provisions of SECTION 2.14(c) apply to this SECTION 9.10
to the same extent that they apply to the provisions of SECTION 2.14(a).

                                  SECTION 10.

                                 MISCELLANEOUS

     10.1   AMENDMENTS, ETC.  No amendment or waiver of any provision of this
Agreement, nor consent to any departure by any Borrower therefrom, shall in any
event be effective, unless the same shall be in writing and signed by Required
Lenders, and then such waiver or consent shall be effective only in the specific
instance and for the specific purpose for which given; provided, however, that
no amendment, waiver, or consent shall, unless in writing and signed by all
Lenders, do any of the following: (a) waive any of the conditions specified in
SECTION 3.1 or 3.2 (if and to the extent that the Borrowing which is the subject
of such waiver would involve an increase in the Total Utilization of Commitments
over the Total Utilization of Commitments outstanding immediately prior to such
Borrowing); (b) increase the Global Commitment or Maximum Canadian Commitment of
any Lender or subject Lenders to any additional obligations; (c) reduce the
principal of, or interest on, the Advances or change the BA Discount Rate or the
BA Fees, or reduce any other fees or other amounts payable hereunder; (d)
postpone any date fixed for any payment of principal of, or interest on, the
Advances or any fees or other amounts payable hereunder; (e) make any change
which would alter the percentage of the Global Commitments or of the Total
Utilization of Commitments, or the number of Lenders, which shall otherwise be
required for Lenders or any of them to take any action hereunder; (f) amend this
SECTION 10.1; or (g) release Murphy from any of its obligations under the
Guaranty Agreement; and provided further, that no amendment, waiver, or consent
affecting the rights or duties of any Agent under this Agreement shall be
effective unless in writing and signed by such Agent in addition to Lenders
required to take such action.

     10.2   NOTICES. All notices and other communications provided for herein
and in the other Loan Documents (including, without limitation, any
modifications of, or waivers or consents under, this Agreement or the other Loan
Documents) shall be given or made by telex, telecopy, telegraph, cable, courier,
or U.S. Mail or Canada Post in writing and telexed, telecopied, telegraphed,
cabled, mailed, or delivered to the intended recipient at the "Address for
Notices" specified on SCHEDULE 1 or in the other Loan Documents or, as to any
party, at such other address as shall be designated by such party in a notice to
each other party. Except as otherwise provided in this Agreement or in the other
Loan Documents, all such communications shall be deemed to have been duly given
when transmitted by telex or telecopier, delivered to the telegraph or cable
office or personally delivered, or, in the case of a mailed notice, when
actually received.

                                  Ex. 4.1-44
<PAGE>
 
     10.3   NO WAIVER; REMEDIES.  No failure on the part of any Lender or any
Agent to exercise, and no delay in exercising, any right hereunder shall operate
as a waiver thereof; nor shall any single or partial exercise of any such right
preclude any other or further exercise thereof or the exercise of any other
right. The remedies herein provided are cumulative and not exclusive of any
remedies provided by law.

     10.4   COSTS, EXPENSES AND TAXES.  Each Borrower hereby agrees to pay on
demand: (a) all reasonable costs and expenses of each Agent and Arranger in
connection with the preparation, negotiation, syndication, execution, and
delivery of this Agreement and the other Loan Documents including, without
limitation, the reasonable legal fees and expenses of legal counsel for each
Agent; (b) all reasonable costs and expenses of each Agent in connection with
any and all amendments, modifications, renewals, extensions, and supplements of
any of the Loan Documents; (c) all reasonable costs and expenses of each Agent
and Lenders in connection with any Potential Default or Event of Default and the
enforcement of this Agreement or any other Loan Document, including, without
limitation, the fees and expenses of legal counsel for each Agent and Lenders;
and (d) all transfer, stamp, documentary, or other similar taxes, assessments,
or charges levied by any Governmental Authority in respect of this Agreement or
any of the other Loan Documents (other than costs, expenses, taxes, assessments,
or charges levied with regard to any Assignment or Participation).

     10.5   RIGHT OF SET-OFF. Upon (a) the occurrence and during the continuance
of any Event of Default, and (b) the making of the request specified by SECTION
7.2 to authorize Domestic Administrative Agent to declare the Obligation due and
payable pursuant to the provisions of SECTION 7.2, each Lender is hereby
authorized at any time and from time to time, to the fullest extent permitted by
applicable 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 any
Borrower against any and all of the Obligation of such Borrower now or hereafter
existing under this Agreement and the Advances made by such Lender, irrespective
of whether or not such Lender shall have made any demand under this Agreement
and although such obligations may be unmatured. Each Lender agrees promptly to
notify such Borrower and the Applicable Agent 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 10.5 are in addition to other rights and remedies
(including, without limitation, other rights of set-off) which such Lender may
have.

     10.6   BINDING EFFECT.  This Agreement shall become effective when it shall
have been executed by Borrowers and Agents and when Domestic Administrative
Agent shall have been notified by each Lender that such Lender has executed it
and thereafter shall be binding upon and inure to the benefit of Borrowers,
Agents, and each Lender and their respective successors and assigns.

     10.7.  ASSIGNMENTS AND PARTICIPATIONS.

      (a)   Each Lender may assign to one or more banks or other entities all or
a portion of its rights and obligations under this Agreement (including, without
limitation, all or a portion of its Commitments and the Advances owing to it);
provided, however, that (i) each such assignment shall be of a constant, and not
a varying, percentage of all of the rights and obligations of Lenders under this
Agreement, (ii) the amount of the Commitments of the assigning Lender being
assigned pursuant to each such assignment (determined as of the date of the
Assignment and Acceptance with respect to such assignment) shall in no event be
less than $10,000,000 and shall be an integral multiple of $1,000,000 (or, if
less, the unpaid Obligation to such Lender), (iii) each such assignment shall be
to an assignee approved in writing by Domestic Administrative Agent and, so long
as no Event of Default exists, Murphy, and (iv) the parties to each such
assignment shall execute and deliver to Domestic Administrative Agent, for its
acceptance and recording in the Register, an Assignment and Acceptance, together
with a processing fee of $2,500. Upon such execution, delivery, acceptance, and
recording, from and after the effective date specified in each Assignment and
Acceptance, which effective date shall be at least (3) three Business Days after
the execution thereof, (A) the assignee thereunder shall be a party hereto and,
to the extent that rights and obligations hereunder have been assigned

                                  Ex. 4.1-45
<PAGE>
 
to it pursuant to such Assignment and Acceptance, have the rights and
obligations of a Lender hereunder, and (B) the assigning Lender 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).

      (b)   By executing and delivering an Assignment and Acceptance, the
assigning Lender 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, the 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) the assigning Lender makes no representation or
warranty and assumes no responsibility with respect to the financial condition
of any Borrower or the performance or observance by any Borrower of any of its
obligations under this Agreement or any other instrument or document furnished
pursuant hereto; (iii) the assignee confirms that it has received a copy of this
Agreement, together with copies of the financial statements referred to in
SECTION 4.5 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) the assignee will, independently and without
reliance upon any Agent, the 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) the assignee appoints and authorizes each Agent to take such
action as agent on its behalf and to exercise such powers under this Agreement
as are delegated to each Agent by the terms hereof, together with such powers as
are reasonably incidental thereto; and (vi) the 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)   Domestic Administrative Agent shall maintain at its address referred
to in SECTION 10.2 a copy of each Assignment and Acceptance delivered to and
accepted by it and a register for the recordation of the names and addresses of
each Lender and the Commitments of, and principal amount of the 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
Borrowers, Agents, and 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 Murphy 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, Domestic Administrative Agent shall, if such
Assignment and Acceptance has been completed and is in substantially the form of
EXHIBIT B hereto, and if the processing fees required by this SECTION 10.7 have
been paid to Domestic Administrative Agent, (i) accept such Assignment and
Acceptance, (ii) record the information contained therein in the Register, (iii)
give prompt notice thereof to Murphy, and (iv) send a copy thereof to Murphy.

      (e)   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, without limitation, all or a portion of its Commitments
and the Advances owing to it); provided, however, that (i) such Lender's
obligations under this Agreement (including, without limitation, its Commitments
to Borrowers hereunder) shall remain unchanged, (ii) such Lender shall remain
solely responsible to the other parties hereto for the performance of such
obligations, (iii) Borrowers, Agents, and each other Lender shall continue to
deal solely and directly with such Lender in connection with such Lender's
rights and obligations under this Agreement, and (iv) after giving effect to
such participation, the aggregate amount of all participations of such Lender
does not exceed fifty percent (50%) of such Lender's Commitments or Obligation,
or if the Commitments have been 

                                  Ex. 4.1-46
<PAGE>
 
terminated, then of the aggregate amount of the Obligation payable to such
Lender; and provided further, however, that such Lender shall not agree with any
such bank or other financial institution to permit such bank or other financial
institution to enforce the obligations of Borrowers relating to the Obligation
or to approve of any amendment, modification, or waiver of any provision of this
Agreement (other than amendments, modifications, or waivers with respect to any
decrease in any fees payable hereunder or the amount of principal or rate of
interest which is payable in respect of the Obligation or any extension of the
dates fixed for the payment thereof).

      (f)   Any Lender may, in connection with any assignment or participation
or proposed assignment or participation pursuant to this SECTION 10.7, disclose
to the assignee or participant or proposed assignee or participant, any
information relating to Borrowers furnished to such Lender by or on behalf of
Borrowers; provided that, prior to any such disclosure, the assignee or
participant or proposed assignee or participant shall agree to preserve the
confidentiality of any confidential information relating to Borrowers received
by it from such Lender .

      (g)   Notwithstanding the foregoing, any Lender may assign all or any
portion of its rights and obligations under this Agreement to an Affiliate of
such Lender.  In addition, any Lender may at any time assign as collateral all
or any portion of its rights under this Agreement to a Federal Reserve Bank or
to Bank of Canada or the Canada Deposit Insurance Corporation; provided that no
such assignment shall release a Lender from any of its obligations hereunder.
In connection with any such assignment or proposed assignment to a Federal
Reserve Bank or to Bank of Canada or the Canada Deposit Insurance Corporation,
each Borrower will, promptly upon the request of any Lender, execute and deliver
to such Lender a note in substantially the form of EXHIBIT F.

      (h)   This SECTION 10.7 sets forth the exclusive manner by which a Lender
may assign its rights and obligations hereunder or sell participations in or to
its rights and obligations hereunder.

      (i)   No Borrower may assign or delegate any rights or obligations
hereunder without the prior written consent of each Lender.

     10.8   GOVERNING LAW; SUBMISSION TO JURISDICTION.

      (A)   THIS AGREEMENT AND ANY NOTES AND THE RIGHTS AND OBLIGATIONS OF THE
PARTIES UNDER THIS AGREEMENT AND ANY NOTES SHALL BE GOVERNED BY, AND CONSTRUED
AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

      (B)   THE PARTIES AGREE THAT NEW YORK, NEW YORK SHALL BE A PROPER PLACE OF
VENUE FOR ALL SUITS TO ENFORCE PERFORMANCE OF THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS, AND EACH PARTY EXPRESSLY AGREES TO THE EXERCISE OF PERSONAL
JURISDICTION OVER IT IN ANY COURT OF APPROPRIATE SUBJECT MATTER JURISDICTION IN
NEW YORK, NEW YORK IN ANY SUCH SUIT.

     10.9   EXCEPTIONS TO COVENANTS.  Borrower may not take or fail to take any
action that is permitted as an exception to any of the covenants contained in
any Loan Document if that action or omission would result in the breach of any
other covenant contained in any Loan Document.

     10.10  SURVIVAL.  All covenants, agreements, undertakings, representations,
and warranties made in any of the Loan Documents survive all closings under the
Loan Documents until payment in full of the Obligation and termination of this
Agreement, except that SECTIONS 2.10, 2.11, 2.14, 8.5, 10.4, and 10.15 (together
with any other provisions in the Loan Documents which expressly provides that it
shall survive termination of this Agreement as to matters arising or accruing
prior to termination of this Agreement) shall 

                                  Ex. 4.1-47
<PAGE>
 
survive termination of this Agreement; and such covenants, agreements,
undertakings, representations, and warranties, except as otherwise indicated,
are not affected by any investigation made by any party.

     10.11  INVALID PROVISIONS.  Any provision in any Loan Document held to be
illegal, invalid, or unenforceable is fully severable; the appropriate Loan
Document shall be construed and enforced as if that provision had never been
included; and the remaining provisions shall remain in full force and effect and
shall not be affected by the severed provision.  Each Agent, each Lender, and
each Borrower party to the affected Loan Document agree to negotiate, in good
faith, the terms of a replacement provision as similar to the severed provision
as may be possible and be legal, valid, and enforceable.

     10.12  MAXIMUM RATE.  Regardless of any provision contained in any Loan
Document, no Lender shall ever be entitled to contract for, charge, take,
reserve, receive, or apply, as interest on the Obligation, or any part thereof,
any amount in excess of the Maximum Rate, and, if any Lender ever does so, then
any excess shall be deemed a partial prepayment of principal and treated
hereunder as such and any remaining excess shall be refunded to Borrowers.  In
determining if the interest paid or payable exceeds the Maximum Rate, Borrowers
and Lenders shall, to the maximum extent permitted under applicable law, (a)
treat all Borrowings as but a single extension of credit (and Lenders and
Borrowers agree that such is the case and that provision herein for multiple
Borrowings is for convenience only), (b) characterize any non-principal payment
as an expense, fee, or premium rather than as interest, (c) exclude voluntary
prepayments and the effects thereof, and (d) amortize, prorate, allocate, and
spread the total amount of interest throughout the entire contemplated term of
the Obligation; provided that if the Obligation is paid and performed in full
prior to the end of the full contemplated term thereof, and if the interest
received for its actual period of existence thereof exceeds the Maximum Amount,
then Lenders shall refund any excess (and Lenders shall not, to the extent
permitted by law, be subject to any penalties provided by any laws for
contracting for, charging, taking, reserving, or receiving interest in excess of
the Maximum Amount).

     10.13  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.

     10.14  NOT IN CONTROL.  Nothing in any Loan Document gives or may be deemed
to give to any Agent or any Lender the right to exercise control over any
Company, assets, affairs, or management or to preclude or interfere with any
Company's compliance with any Legal Requirement or require any act or omission
by any Company that may be harmful to Persons or property.  Any materiality or
substantiality qualifier of any representation, warranty, covenant, agreement,
or other provision of any Loan Document is included for credit documentation
purposes only and does not imply, and shall not be deemed to mean, that any
Agent or any Lender acquiesces in any non-compliance by any Company with any
Legal Requirement, document, or otherwise or does not expect any Company to
promptly, diligently, and continuously carry out all appropriate removal,
remediation, compliance, closure, or other activities required or appropriate in
accordance with all Legal Requirements, including all Environmental Laws.

     10.15  INDEMNIFICATION.  EACH BORROWER SHALL INDEMNIFY, PROTECT, AND HOLD
EACH AGENT, ARRANGER, EACH LENDER, AND THEIR RESPECTIVE AFFILIATES, PARENTS, AND
SUBSIDIARIES, AND EACH OF THE FOREGOING PARTIES' RESPECTIVE DIRECTORS, OFFICERS,
EMPLOYEES, AGENTS, SUCCESSORS, AND ASSIGNS (COLLECTIVELY, THE "INDEMNIFIED
PARTIES") HARMLESS FROM AND AGAINST ANY AND ALL PRESENT AND FUTURE, KNOWN AND
UNKNOWN, FIXED AND CONTINGENT, LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES,
PENALTIES, ACTIONS, JUDGMENTS, SUITS, CLAIMS, AND PROCEEDINGS AND ALL REASONABLE
AND NECESSARY COSTS, EXPENSES (INCLUDING, WITHOUT LIMITATION, ALL REASONABLE
ATTORNEYS' FEES AND LEGAL EXPENSES, AND AMOUNTS PAID IN SETTLEMENT WHETHER OR
NOT SUIT IS BROUGHT), AND DISBURSEMENTS OF ANY KIND OR NATURE WHATSOEVER (THE
"INDEMNIFIED LIABILITIES") WHICH MAY AT ANY TIME BE IMPOSED ON, INCURRED BY, OR
ASSERTED AGAINST THE INDEMNIFIED PARTIES, IN ANY WAY RELATING TO OR ARISING OUT
OF ANY LOAN DOCUMENT OR TRANSACTION CONTEMPLATED BY ANY LOAN 

                                  Ex. 4.1-48
<PAGE>
 
DOCUMENT, OR ANY TRANSACTION CONTEMPLATED BY ANY LOAN DOCUMENT; PROVIDED THAT
BORROWERS SHALL HAVE NO OBLIGATION HEREUNDER TO ANY INDEMNIFIED PARTY WITH
RESPECT TO ANY INDEMNIFIED LIABILITY ARISING FROM THE FRAUD, GROSS NEGLIGENCE,
OR WILLFUL MISCONDUCT OF SUCH INDEMNIFIED PARTY OR ANY ASSOCIATED PERSON OF SUCH
INDEMNIFIED PARTY. AS USED IN THIS PARAGRAPH, THE TERM "ASSOCIATED PERSON"
MEANS, WITH RESPECT TO ANY PERSON, THE AFFILIATES, PARENTS, SUBSIDIARIES,
DIRECTORS, OFFICERS, EMPLOYEES, AGENTS, SUCCESSORS, AND ASSIGNS OF SUCH PERSON,
OR OF ANOTHER PERSON OF WHICH SUCH PERSON IS ALSO AN ASSOCIATED PERSON. THE
PROVISIONS OF AND UNDERTAKINGS AND INDEMNIFICATION SET FORTH IN THIS SECTION
SHALL SURVIVE THE SATISFACTION AND PAYMENT OF THE OBLIGATION AND TERMINATION OF
THIS AGREEMENT.

     10.16  ENTIRETY.  THE LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN
BORROWERS, LENDERS, AND ADMINISTRATIVE AGENT AND MAY NOT BE CONTRADICTED BY
EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS BY SUCH
PARTIES.  THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN SUCH PARTIES.

                                 SCHEDULE 6.1

                                EXISTING LIENS

1.   Lien to the Province of Alberta, Canada on Murphy Oil Company Ltd.'s five
     percent (5%) interest in Syncrude.  This lien secures a non-recourse loan
     given at the time of purchase of the interest.  The outstanding balance
     payable on the debt as of September 30, 1997, was U.S. $42,148,000.  Final
     payment on the debt is due December, 1998.

2.   Lien to National Trust Company on Murphy Oil Company Ltd.'s six and one
     quarter percent (6 1/4%) interest in the Hibernia field offshore
     Newfoundland.  This lien secures a non-recourse Canadian Government's
     guarantee of Murphy Oil Company Ltd.'s borrowing to finance the development
     of the field.  The amount of debt secured by the lien fluctuates due to
     additional facilities available, payment on facilities and the rate of
     exchange between the Cdn$ and the U.S.$.  As of September 30, 1997, the
     outstanding balance payable was U.S. $157,378,000.  The retirement schedule
     of the guarantee varies but will not extend beyond 2008.

3.   No attempt has been made to list liens related to capital leases which have
     resulted in assets being recorded in the consolidated financial statements.
     These assets consist of various items ranging from computer equipment to
     refinery land.  The outstanding balance of this imputed debt as of
     September 30, 1997, was U.S. $872,000.  It is Murphy Oil Corporation's
     position that even though a legal document may exist, if use and enjoyment
     of our assets can not be interrupted by the enforcement of the document for
     non-payment of recorded debt, then a reportable lien does not exist under
     this Agreement.

         may only be based upon assumptions and subject to exceptions
    and qualifications, and must otherwise be in form and substance, as may
         be acceptable to Agents (based upon advice of their counsel).

Capitalized terms used herein shall, unless otherwise indicated, have the
respective meanings set forth in the Credit Agreement.

     1.   Murphy Oil Corporation, Murphy Oil USA, Inc., and Murphy Exploration &
Production Company (the "U.S. BORROWERS") are each a corporation duly
incorporated, validly existing, and in good standing under the laws of the State
of Delaware with corporate power to own and operate its business and properties
and to carry on its business as presently conducted and to execute and perform
the Credit Agreement, as amended, and to borrow thereunder, and, in the case of
Murphy, to guaranty the obligations of the Subsidiary Borrowers referred to in
the Credit Agreement.

     2.   Murphy is the owner, either directly or through a wholly-owned
subsidiary, of all of the outstanding Common Stock of each of the Subsidiary
Borrowers and all of such Common Stock is fully paid and non-assessable; none of
the Subsidiary Borrowers has any class of stock outstanding other than Common
Stock.

     3.   The Credit Agreement (including the Guaranty referred to therein) has
been duly authorized, approved, and adopted by all necessary corporate action of
the U.S. Borrowers.

     4.   The execution, delivery, and performance by Murphy and the Subsidiary
Borrowers of the Credit Agreement and borrowing thereunder will not contravene
any applicable provision of law, and will not conflict with or result in the
breach of or accelerate the performance required by any of the terms,
conditions, or provisions of the Certificate of Incorporation or Bylaws of the
U.S. Borrowers or any covenant, agreement, or understanding known to me to which
Murphy or any of the Subsidiary Borrowers is a party or any order, ruling,
decree, judgment, arbitration award, or stipulation known to me to which Murphy
or any of the Subsidiary Borrowers is subject.

     5.   The Loan Documents to which each U.S. Borrower is a party have been
duly executed, presented, and delivered.

     6.   No Authorization of any Governmental Authority or of any other Person
is required in connection with the execution, delivery, and performance of the
Loan Documents or the borrowing and repayment of money by each U.S. Borrower
thereunder.

     7.   The Loan Documents constitute the legal and binding obligations of
each Borrower, enforceable against each Borrower in accordance with their
respective terms (except as enforcement may be subject to any applicable
bankruptcy, insolvency, or similar laws affecting the enforcement of creditors'
rights generally).

     8.   There are no actions, suits, or proceedings pending or threatened
against any Borrower, which, if adversely determined, could be a Material
Adverse Event.

     9.   An Arkansas court or a federal court in the State of Arkansas, in a
case properly presented, would uphold the New York choice of law provisions in
the Loan Documents.

                                 Ex. 4.1-SE17
<PAGE>
 
     10.  The submission in the Credit Agreement by Borrowers to the
nonexclusive jurisdiction of the courts of the State of New York is binding and
enforceable against Borrowers.

     11.  To the best of my knowledge, no Borrower is an "investment company" or
a company "controlled" by an "investment company" as such terms are defined in
the Investment Company Act of 1940, as amended, or subject to regulation under
the Public Utility Holding Company Act of 1935, as amended, the Federal Power
Act, as amended, the Interstate Commerce Act, as amended, or any federal or
state Legal Requirement limiting its ability to incur Debt or to create Liens on
any of its properties or assets to secure such Debt.

     12.  The Obligation of each U.S. Borrower will rank at least pari passu
with the claims of all other unsecured and unsubordinated creditors of each U.S.
Borrower.

                FORM OF OPINION OF BORROWERS' CANADIAN COUNSEL


    Bennett Jones Verchere, Special Canadian Counsel to Canadian Borrower, 
                             is to opine to Agents
            and Lenders as to the following matters, which opinion
         may only be based upon assumptions and subject to exceptions
    and qualifications, and must otherwise be in form and substance, as may
         be acceptable to Agents (based upon advice of their counsel).

Capitalized terms used herein shall, unless otherwise indicated, have the
respective meanings set forth in the Credit Agreement.

     1.   Canadian Borrower is a corporation duly created by amalgamation and
validly existing under the laws of Canada with corporate power to own and
operate its business and properties, to carry on its business as presently
conducted in the Provinces of Alberta and Saskatchewan, to execute, deliver, and
perform the Credit Agreement and to borrow monies from you thereunder.

     2.   Murphy is the owner of record of all outstanding common shares of
Canadian Borrower, all such common shares are fully paid and non-assessable and
there are no other outstanding shares of any class of Canadian Borrower.

     3.   The Credit Agreement has been duly authorized, approved, and adopted
by all necessary corporate action of Canadian Borrower, and has been duly
executed and delivered, and the Credit Agreement constitutes a valid and legally
binding obligation of Canadian Borrower, enforceable in accordance with its
terms.

     4.   The execution, delivery, and performance by Canadian Borrower of the
Credit Agreement and borrowings by Canadian Borrower thereunder will not
contravene any applicable provision of Alberta law or the laws of Canada
applicable in Alberta, and will not conflict with or result in the breach of or
accelerate the performance required by any of the terms, conditions, or
provisions of the constating documents of Canadian Borrower, being its articles
of amalgamation, any articles of amendment and its by-laws, or any covenant,
agreement, or understanding known to us to which Canadian Borrower is a party or
any order, ruling, decree, judgment, arbitration award, or stipulation known to
us to which Canadian Borrower is subject.

     5.   Neither the execution and delivery by Canadian Borrower of the Credit
Agreement, nor the performance by Canadian Borrower of its obligations
thereunder, nor compliance by Canadian Borrower with the terms and provisions
thereof will require the payment of any taxes, fees, or other governmental
charges in Alberta.

     6.   No Authorization of any Governmental Authority or of any other Person
is required in connection with the execution, delivery, and performance by
Canadian Borrower of the Credit Agreement or the borrowing and repayment of
money by Canadian Borrower thereunder.

     7.   There are no actions, suits, or proceedings pending or threatened
against Canadian Borrower in the Judicial District of Calgary, Province of
Alberta, which, if adversely determined, could be a Material Adverse Event.

     8.   A court in Alberta, if it assumed jurisdiction to render judgment in
respect of the Credit Agreement, would uphold the New York choice of law
provisions in the Credit Agreement.

                                 Ex. 4.1-SE19
<PAGE>
 
     9.   A final and conclusive judgment in personam granted by a court of
competent jurisdiction in the State of New York, which is not impeachable as
void or voidable under the internal laws of New York, may be enforced in a court
in Alberta by an action or counterclaim for the sum certain under such judgment.

     10.  The submission in the Credit Agreement by Canadian Borrower to the
nonexclusive jurisdiction of the courts of the State of New York is binding and
enforceable against Canadian Borrower.

     11.  The Obligation of Canadian Borrower will rank at least pari passu in
the terms of payment with all indebtedness which is not secured or the subject
of any statutory trust or preference or which is not expressly and effectively
subordinated in right of payment to any other indebtedness of Canadian Borrower.

     12.  Canadian Borrower is not entitled to claim immunity from legal process
of the enforcement of any judgment of a court of competent jurisdiction, whether
generally or in relation to any specific assets.

                                  EXHIBIT C-3

                   FORM OF OPINION OF BORROWERS' UK COUNSEL


 J. N. Copeland, Special U.K. Counsel to U.K. Borrower, is to opine to Agents
            and Lenders as to the following matters, which opinion
         may only be based upon assumptions and subject to exceptions
    and qualifications, and must otherwise be in form and substance, as may
     be acceptable to Agents (based upon advice of their special counsel).

Capitalized terms used herein shall, unless otherwise indicated, have the
respective meanings set forth in the Credit Agreement.

     1.   U.K. Borrower is a company duly incorporated, validly existing, and in
good standing under the laws of England, and has all power and authority
required to own its property and carry on its business as presently conducted
and proposed to be conducted.  U.K. Borrower is duly qualified or licensed to do
business in each jurisdiction where the nature of the business in which it is
engaged makes such qualification or licensing necessary, including England.

     2.   U.K. Borrower has the requisite corporate power to execute, deliver,
and perform the terms and provisions of the Loan Documents, and all other
documents and instruments delivered pursuant to the terms of such Loan
Documents, and has taken all appropriate corporate action necessary to duly
authorize (a) the execution, delivery, and performance by U.K. Borrower of the
terms and provisions of the Loan Documents, and (b) the performance by U.K.
Borrower of its obligations under the Loan Documents.

     3.   The Loan Documents to which U.K. Borrower is a party have been duly
executed and delivered by U.K. Borrower.

     4.   Neither the execution and delivery by U.K. Borrower of the Loan
Documents, nor the performance by U.K. Borrower of its obligations thereunder,
nor compliance by U.K. Borrower with the terms and provisions thereof, will (a)
contravene any provision of any Legal Requirement of England, to which U.K.
Borrower is subject, or to the best of my knowledge, after due inquiry, conflict
with, or result in any breach of, any material agreement, mortgage, indenture,
deed of trust, or other instrument known to me to which U.K. Borrower may be
subject, or result in the creation of any Lien in respect of any property of
U.K. Borrower (other than Liens in your favor), (b) contravene any English
Authorization, judgment, or decree applicable to U.K. Borrower, (c) violate any
provision of the Constituent Documents of U.K. Borrower, or (d) require the
payment of any taxes, fees, or other governmental charges.

     5.   No Authorization of any English Governmental Authority or of any other
English Person is required in connection with the execution, delivery, and
performance by U.K. Borrower of the Loan Documents or the borrowing and
repayment of money by U.K. Borrower thereunder.

     6.   To the best of my knowledge, after due inquiry, there are no actions,
suits, or proceedings pending or threatened against U.K. Borrower, which, if
adversely determined, could be a Material Adverse Event.

     7.   The choice of the laws of the State of New York as the law expressed
to govern the Loan Documents is a valid choice of governing law, which would
normally be applied by English courts.

     8.   On the assumption that the Loan Documents create valid and binding
obligations under the laws of the State of New York, the provisions of the Loan
Documents whereby U.K. Borrower submits to 

                                 Ex. 4.1-SE21
<PAGE>
 
the non-exclusive jurisdiction of the courts of the State of New York are
binding and enforceable against U.K. Borrower.

     9.   The Obligation of U.K. Borrower will rank at least pari passu with the
claims of all other unsecured and unsubordinated creditors of U.K. Borrower not
being indebtedness of a preferential creditor.

     10.  U.K. Borrower is not entitled to claim immunity from legal process of
the enforcement of any judgement of a court of competent jurisdiction, whether
generally or in relation to any specific assets.

     11.  A final and conclusive judgment for a debt or sum of money (not being
a sum payable in respect of taxes or other charges of a like nature or in
respect of a fine or other penalty) properly obtained against U.K. Borrower by a
court of competent jurisdiction in the State of New York being recognized by the
English courts as having jurisdiction to give that judgment in respect of any
suit, action, or proceeding arising out of or in relation to the Loan Documents
may be enforced against U.K. Borrower in the courts of England without re-
examination or re-litigation of the merits of the substantive matters
adjudicated upon.

Murphy Oil Corporation is a worldwide oil and gas exploration and production
company with refining and marketing operations in the United States and the
United Kingdom.

Strong management, good strategic decisions and an entrepreneurial approach
throughout the Company have enabled Murphy to stake its claim as one of the
industry's strongest performers. In 1997, proved reserves grew for the seventh
consecutive year. Production rose 14 percent to record levels and discoveries
currently under development support continued growth well into the next century.
Aggressive acreage acquisition efforts focused on securing a strong position in
the deepwater Gulf of Mexico and the U.K. Atlantic Margin. Refining, marketing
and transportation operations emerged from a prolonged downturn to post
impressive operational and financial performances. The Company's commitment to
workplace and environmental safeguards continued to result in safety performance
well above general industry averages and operations that utilize cutting-edge
technology and sound science to protect the world's natural resources.

Against the backdrop of 1997's success and given the Company's strength across
an array of important indicators--a pristine balance sheet, growing production
and reserves, a robust exploratory prospect portfolio and sound operating
performance--Murphy is solidly positioned for future growth and increased
shareholder value.

[GRAPH - CAPITAL EXPENDITURES]

[GRAPH - LONG-TERM OBLIGATIONS]



EXPLORATION AND PRODUCTION
Upstream operations are the premier long-term growth vehicle for Murphy Oil. The
Company has substantial exploration acreage positions in its politically secure
core areas of the Gulf of Mexico, Canada and the U.K., and in a number of
frontier areas that provide potential for significant reserve additions. Core
area exploration is highlighted by deepwater activity in the Gulf of Mexico, and
a frontier area of particular interest is the emerging Atlantic Margin play,
west of the U.K. and Ireland. Murphy's active and diversified exploration
program is designed to add to an already growing production profile. The first
of several significant additions to the Company's established core area
production was realized in late 1997 with the start-up of the Hibernia oil
field, offshore eastern Canada, the first field to be placed on stream in the
Jeanne d'Arc Basin. U.K. oil production is set to double with a mid-1998
commencement of production from two fields, including the second field to be
placed on stream in the Atlantic Margin. Murphy also has an interest in
Syncrude, the world's largest producer of light, sweet crude oil from oil sands,
where plans for significant increases in production have been announced.
Finally, further oil production growth is assured with the recent approval of
plans to develop the Terra Nova field, located to the southeast of Hibernia. All
told, Murphy has one of the most attractive production profiles in the oil
industry.

REFINING, MARKETING AND TRANSPORTATION
The resurgence of Murphy's downstream operations exemplifies the Company's
dedication to lean, tough and smart management that produces bottom-line
results. In 1997, record onstream efficiency and the ability to process less
expensive crude oil enabled Murphy's U.S. downstream operation to record its
most profitable year ever. A program with Wal-Mart to build retail stations in
the parking lots of Wal-Mart Supercenters and SAM'S Clubs in selected markets is
beginning to tap a market niche already established overseas but heretofore
underdeveloped in the U.S. In the U.K., where Murphy has partial ownership in a
refinery serving a marketing area covering much of England and Wales, profits
were up 48 percent. The Company also purchases, transports and resells crude oil
in Canada.

Dear Fellow Shareholder:

This is the fourth time I have had the privilege to report to my fellow
shareholders as President and CEO of Murphy Oil Corporation. It is with pride
and great satisfaction that I tell you Murphy is a thriving and vibrant company,
well positioned for continued growth and success. Naturally, the most tangible
evidence is financial performance. In 1997, Murphy Oil Corporation earned $132.4
million, $2.94 a share, a net income record from exploration and production and
refining and marketing operations, breaking a mark set in 1996. Return on
capital employed of 10.4 percent in 1997 marked the second consecutive year that
this important performance measure scored in double digits.

In my report to you last year, I noted that 1996 was "a turnaround year" for us
and a year of significant

corporate change as Deltic Timber Corporation was spun off to shareholders as a
debt-free, independent, market-valued company. The bottom-line results from
1997, which continued 1996's record performance, are a clear indication that our
turnaround will, in fact, stay around. Your Company's long-term prospects and
current value are stronger than ever.

Let's review the facts. Proved reserves increased for the seventh consecutive
year as your Company replaced 165 percent of its worldwide hydrocarbon
production in 1997. Production increased 14 percent on a barrel-equivalent
basis, setting a Company record, primarily due to natural gas discoveries made
in the Gulf of Mexico during 1996 that were promptly put on stream. There is
much more to come. In November, the Hibernia field (6.5%) commenced production--
on budget, ahead of schedule and bigger than originally advertised. Conservative
reserve projections now put the field at 615 million barrels compared to our
estimate of 485 million barrels when we acquired the field in 1992. Peak
production will be 135,000 barrels a day, although plans are being studied to
increase that figure substantially. Hibernia ownership ensures Murphy of a large
production increase at very low equity cost and surprisingly low lifting costs.

Hibernia improves our already strong production profile that includes proven
performers such as Syncrude (5%). Syncrude had a very positive financial impact
on Murphy in 1997, as earnings from this operation totaled $14.3 million. The
project's owners are currently investing in technology designed to improve
environmental protection and energy efficiency, while also increasing product
yield. In fact, Syncrude announced plans during 1997 to more than double its
production during the next 10 years to over 400,000 barrels a day or
approximately 20,000 barrels a day net to Murphy. Further augmenting production
growth is the midyear 1998 start-up of two U.K. fields--Schiehallion (5.9%) and
Mungo/Monan (12.7%). These additions will bring our production in northwestern
Europe to nearly 30,000 barrels a day. Lastly, but significantly, in January
1998 Canadian government approval was received to develop the Terra Nova field
(12%), located 22 miles southeast of Hibernia. First oil at Terra Nova is
anticipated no later than 2001.

What about production growth beyond this? Exploration efforts in 1997 led to
discoveries at Ship Shoal Blocks 166/167 (33-50%) and Eugene Island Block 335
(60%). The latter comes on stream in the first quarter of 1999, adding
approximately 25 million cubic feet a day to our U.S. natural gas production.
Importantly, in 1997 we stepped up Gulf of Mexico deepwater exploration
activity. After spending four years building an acreage position (we now own 80
deepwater leases) and forging drilling partnerships, we will spud four deepwater
wildcats during the balance of 1998. Furthermore, we added to our Atlantic
Margin position west of Britain and Ireland, and we now participate in six
separate tranches in this high-potential play.

Historically, downstream has been a smaller part of the Murphy portfolio, but
last year it was an extremely important one. In 1997, Murphy's downstream turned
in a solid financial and operational performance. Worldwide downstream
operations earned $56.7 million in 1997 as compared to $14.1 million in 1996.
Our U.S. refining and marketing operation turned in its best year ever, earning
$41.3 million. Operationally, downstream continued its strong performance, with
a composite 98 percent onstream time at the U.S. refineries. New records were
also established for refinery throughputs and product sales volume.

At Murphy, we are building on a legacy of leadership and innovation.  In today's
world, that translates into a global perspective and a resolve to capitalize on 
opportunities.

                                       5
<PAGE>
 
Furthermore, downstream operations reflect the entrepreneurial spirit we have
worked hard to foster throughout all facets of the Murphy enterprise. Murco
Petroleum in the U.K., for example, came back from the scrapped merger with
Chevron and Elf to revitalize promising stations, jettison nonperforming ones,
claim new commercial business and make a handsome profit to boot. In the U.S.,
this entrepreneurship led to a pilot project with Wal-Mart to build service
stations at selected Supercenters and SAM'S Clubs.

This Company continues to pursue with vigor and success our goals of
long-term growth, market expansion, environmental stewardship and aggressive
exploration. Through hard work, creativity and sometimes sheer stubbornness, we
are performing better than ever in one of the most competitive industries in the
world. Nonetheless, the challenges keep coming. The decline in crude oil prices
at the end of 1997 and in early 1998 will exact a financial toll. As always, we
will strive to convert this into opportunities to acquire appropriately priced
assets.

As in most years, there were a number of personal milestones in 1997, two of
which I would especially like to note. Barry Sales, who managed our U.K.
marketing, retired in December after 23 years with Murphy. During his tenure, it
was (and remains) a well-managed and profitable operation. Finally, all of us at
Murphy, and indeed around the state of Arkansas, mourned the death of Johnie
Murphy. She was a great lady, generous of spirit and warm of heart with an
infectious charm. Her gifts to her family, to her community and to this Company
endure.

We thank you for your continued support and confidence.

Murphy Oil Corporation explores for and produces oil and natural gas throughout
the world.

AN OVERVIEW
Murphy's exploration and production programs are the cornerstones of the
Company's plans for growth. Murphy's upstream operations are characterized by
profitable and consistent production growth and a diversified and efficient
exploration program in strategically defined areas. The Company actively pursues
exploration rights in the United States and around the globe, thereby spreading
the risk, while maximizing its ability to identify and develop profitable
fields.

Exploration and production activities earned $85 million in 1997, or 60 percent
of total Company earnings from operating segments. Murphy's proved reserves
increased at year-end 1997 to 362 million barrels of oil equivalent. This is the
seventh consecutive year that the Company's additions to proved reserves have
more than replaced its production.

Worldwide production increased to a record 102,272 barrels of oil equivalent a
day, up 14 percent from 1996 production levels.

  *Before special items.

Murphy's core operating areas include four of the premier oil and natural gas
basins in the world: the Gulf of Mexico, the Canadian Western Sedimentary Basin,
the Jeanne d'Arc Basin off the east coast of Canada and the U.K. North Sea.

The Company's record production in 1997 is largely due to a 23-percent increase
in barrel-equivalent production in the U.S. The increase was due primarily to
the ability of the Company's innovative engineering staff to realize early
production from discoveries made in 1996.

U.S. exploration activity focuses on three distinct areas: deepwater Gulf of
Mexico, the Outer Continental Shelf of the Gulf and onshore South Louisiana.
Murphy's strategic goals are to create significant reserve additions with its
deepwater activity, to maintain production on the shelf while divesting high
lifting cost properties, and to maximize cost efficiencies by realizing early
production opportunities from the onshore program.

Murphy's investment in an emerging core area, offshore eastern Canada, began
paying dividends in 1997 as the Hibernia oil field (6.5%) came on stream. The
Company's interest in the Jeanne d'Arc Basin also includes the nearby Terra Nova
oil field (12%). Industry interest in the exploration potential of the basin is
high, and Murphy participated with nine other companies in a 3-D seismic study
conducted over much of the more prospective areas. Murphy's activities in Canada
also include an interest in Syncrude (5%), the world's largest producer of
synthetic crude oil. Light, sweet crude oil from oil sands could eventually
provide half of Canada's crude oil production.

Murphy's frontier exploration and production activities involve greater risk and
potentially greater reward than those in core areas. Frontier areas include the
U.K. Atlantic Margin, South America, China, Spain, the Philippines, Pakistan and
Alaska.

The U.K. has long been an important part of Murphy's exploration and production
activities, but during 1997, it assumed even greater significance. Production in
the region is expected to double by mid-1998 with the 

                                       9

addition of two new fields. One of these, Schiehallion (5.9%), confirmed
Murphy's assessment of the exploration potential of the Atlantic Margin.
Following this success, the Company expanded its exploration presence in the
area in 1997 by securing a 25-percent interest in more than 650,000 exploration
acres.

South America is home to one of the industry's highest profile unexplored 
basins--the Falkland Islands. Murphy has a 25-percent interest in a block that
will be the site of the first well drilled in the basin.

The history of Murphy's international frontier exploration and its development
of significant production capacity in emerging basins has been guided by a
commitment to seek out opportunities with the potential to build the Company.
That entrepreneurial spirit is tempered and balanced by a continuing focus on
the secure and established basins Murphy knows best. Murphy's management has
developed a strategic and integrated approach to exploration and production that
capitalizes on the Company's historic strengths and positions it for future
growth.

A review by core and frontier areas of the Company's principal exploration and
production activities is presented in the sections that follow. Unless otherwise

In 1997, Syncrude, the world's largest producer of light, sweet crude oil from
oil sands, announced plans to more than double production during the next 10
years to over 400,000 barrels a day, approximately 20,000 barrels net to Murphy.

When production commences in 1998, Schiehallion will be one of only two
producing fields in the U.K. Atlantic Margin. Innovative use of a floating
production system enhances project economics by significantly reducing capital
and operating costs.

[PHOTOGRAPH APPEARS HERE]

Operations in the U.S. are a significant contributor to Murphy's exploration and
production activities. In 1997, U.S. production averaged 45,961 barrels of oil
equivalent a day--a 23-percent increase driven by a 36-percent increase in
natural gas production. During the year, Murphy continued to strengthen its
investment in U.S. exploration by further concentration on three major areas--
deepwater Gulf of Mexico, the Outer Continental Shelf of the Gulf of Mexico and
onshore South Louisiana. The Company added 78 billion cubic feet of natural gas
equivalent to its U.S. proved reserves in 1997.

During 1998, Murphy plans to invest 63 percent of its worldwide exploration
budget in the U.S., with an ongoing emphasis in the Gulf of Mexico on both
deepwater and continental shelf prospects. The Company will continue to pursue
early production opportunities in South Louisiana in an effort to maximize
production gains.

DEEPWATER GULF OF MEXICO
Due to the excellent producibility of the deepwater Gulf of Mexico reservoirs,
progressive expansion of the infrastructure and royalty relief, discoveries in
this area have been consistently profitable.

Murphy was an early entrant in the deepwater Gulf. With the addition of 27
leases (25-100%) in 1997, the Company has a total of 80 deepwater leases in the
Gulf of Mexico. Eight prospects on 11 leases have been further delineated with 
3-D seismic data. At least four of these wells should be drilled in 1998; Murphy
is the operator of two.

One issue of importance in the deepwater Gulf of Mexico is rig availability, and
Murphy has taken steps to ensure that it will have access to equipment to
continue exploration activities in this area. Along with two other oil
companies, Murphy has signed a five-year contract for a deepwater drilling rig.
The agreement provides each company use of the rig for one-third of the
contract. The rig, capable of drilling in depths up to 6,000 feet of water, is
scheduled to be available in mid-1999.

OUTER CONTINENTAL SHELF OF THE GULF OF MEXICO
Murphy also has a major presence on the Outer Continental Shelf of the Gulf of
Mexico. The continental shelf has an established infrastructure and allows for
steady production with lower risk than deepwater exploration. During 1997, the
Company added to its substantial shelf acreage position with the acquisition of
11 new leases (60-80%).

Natural gas production from West Cameron Block 631 (60%), located in 325 feet of
water, began in February 1997, just 10 months after drilling of the second
discovery well, due to the Company's ability to convert existing processing
facilities. Natural gas production from the field averaged 33 million cubic feet
a day for the year.

Similarly, Eugene Island Block 322 (50%), located in 254 feet of water, came on
stream in June 1997, nine months after drilling of the second discovery well and
with the use of an existing processing facility. The discovery on Ship Shoal
Blocks 166/167 (33-50%) came on stream in December 1997. Eugene Island Block 323
(50%) commenced production in February 1998. A satellite structure was installed
in this field, and production is piped to facilities at Eugene Island Block 322.
Combined production from these discoveries averages 32 million cubic feet of
natural gas equivalent a day.

The remaining development wells at Viosca Knoll Block 783 (30%) came on stream
in 1997, and production at this field for the year averaged 25 million cubic
feet of

[PHOTOGRAPH APPEARS HERE]

natural gas equivalent a day. One of Murphy's better discoveries of the year,
Eugene Island Block 335 (60%), is expected to start producing natural gas in
early 1999 at a rate of approximately 25 million cubic feet a day.

The Destin Dome Block 56 unit (33%) is one of the largest undeveloped natural
gas discoveries remaining in the U.S. Located in federal waters 30 miles off the
coast of Florida, three previously drilled exploratory wells have confirmed a
significant reservoir of dry natural gas in the Norphlet sandstone. Murphy and
its two partners filed a development plan with the U.S. Minerals Management
Service in November 1996. A rigorous regulatory process designed to protect the
environment and ensure compatibility with other uses of surrounding areas is
under way. Completion of the process could extend into late 1999.

ONSHORE SOUTH LOUISIANA
Murphy is currently pursuing a program involving third-party review of the
Company's existing 2-D seismic database to identify new prospects, thereby
minimizing cost and spreading risk. Further delineation utilizing 3-D seismic
data is expected to result in the drilling of two to three of these prospects
each year. At year-end 1997, a well at the N.E. Wright field (50%) was in
progress.

CORE EXPLORATION AND PRODUCTION: CANADA
- - --------------------------------------------------------------------------------

Canada is Murphy's largest source of crude oil production, and the Company's
portfolio includes some of the country's legacy properties.

During 1997, Murphy's Canadian production averaged 32,547 barrels of oil
equivalent a day, an increase of 10 percent over 1996 levels. The Company's
Canadian exploration and production operations are located in two primary
geographic areas: the Jeanne d'Arc Basin off Canada's east coast and western
Canada, including the Athabasca Oil Sand Deposit in Alberta.

THE JEANNE D'ARC BASIN -- HIBERNIA AND TERRA NOVA
The initiation of production at Hibernia (6.5%) in November marked a milestone
for Canada and Murphy and provided a springboard for continued growth. Projects
of this magnitude require creative problem-solving ideas and cutting-edge
technological ability and equipment. The partnership that developed Hibernia
brings together those attributes, as well as hundreds of years of exploration
and production experience, making Hibernia a solid investment.

And it is an investment that provides Murphy with an exceptional rate of return.
Due to a favorable financing package negotiated at the time Murphy acquired its
interest, the Company's equity investment in the project as production commenced
was approximately $1.25 a barrel. With a 20-year life span, Hibernia is expected
to be highly profitable well into the future.

Hibernia's production and drilling platform uses state-of-the-art environmental
protection technology to tap one of the world's largest crude oil discoveries of
the past quarter century. Recoverable reserves at Hibernia are conservatively
estimated to be 615 million barrels of oil equivalent. Peak gross production of
approximately 135,000 barrels a day will be reached as rapidly as possible
consistent with high safety and environmental protection standards. Current
estimates indicate that this production level will be achieved by early 1999.
The operating company is studying alternatives whereby additional investment in
equipment and technology could boost production well beyond designed rates.

Hibernia's platform, which is nearly one acre in size, is the first in North
America to use a concrete gravity base structure and the first in the world
designed to withstand

[PHOTOGRAPH APPEARS HERE]

Peak gross production at Hibernia should reach 135,000 barrels of oil a day by
early 1999 and could increase substantially with additional investments of
equipment and technology.

the impact of an iceberg. Two 850,000-barrel, double-hulled tankers, designed to
operate in the harsh environment of the North Atlantic, will load from the
platform and will initially shuttle crude oil directly to refineries until a
Newfoundland onshore terminal is completed in late 1998.

The Company's holdings in the area also include a 12-percent interest in the
Terra Nova oil field, located 22 miles southeast of Hibernia. With estimated
reserves of 300 to 400 million barrels, Terra Nova is projected to come on
stream late in the year 2000, at a gross production rate of approximately
115,000 barrels of oil a day. In early 1998, the Canadian government sanctioned
the project, and the Terra Nova partners announced their decision to proceed
with development.

The Company is actively seeking additional exploration opportunities in the
Jeanne d'Arc Basin and continues to participate in bidding at crown land sales.
Murphy has a 25-percent interest in Cape Race, a 34,000-acre exploration license
located between Hibernia and Terra Nova. Seismic surveys conducted in 1997 are
under evaluation. Should results prove encouraging, an exploratory well could be
drilled in 1999.

WESTERN CANADA--SYNCRUDE
Long-life production in Canada is also provided by Murphy's five-percent working
interest in the Syncrude project, located in the Athabasca Oil Sand Deposit in
Alberta. Syncrude is the world's largest producer of light, sweet crude oil from
oil sands and is the single largest source of oil in Canada. Syncrude combines
mining, extraction and upgrading technologies to convert oil sands to synthetic
crude oil.

Syncrude achieved record gross production during 1997, averaging over 207,000
barrels of oil a day. Murphy's 1997 earnings from the project totaled $14.3
million. With investments in new technology to improve productivity and reduce
costs, this project is expected to remain highly profitable well into the next
century. Syncrude has announced plans to invest a total of $4 billion in
technology and projects that will double production by 2007 and generate an even
lighter, lower sulfur crude oil than is currently being produced.

While Syncrude has historically invested heavily in environmental improvements,
the planned new investments include more than $420 million to improve
environmental protection while increasing product yield. By 2006, sulfur dioxide
emissions per barrel are projected to fall by 70 percent from 1990 levels.
Similarly, Syncrude's production costs are projected to decrease significantly
over the next decade.

WESTERN CANADA--CONVENTIONAL
Murphy's conventional hydrocarbon activities in western Canada are focused on
increasing natural gas production and enhancing the profitability of the
Company's vast heavy oil reserves.

In 1997, the Company was able to maintain its natural gas production through
workovers and development drilling in existing fields. The Company is also
developing a broad natural gas prospect portfolio in Canada and will drill at
least three impact exploratory wells in 1998. In late 1997, a significant gas
discovery at Josephine (50%) in the Peace River Arch added 7.5 billion cubic
feet of proved reserves, augmenting previous reserve additions at Umbach (50%)
and Boundary Lake South (50%). Delineation at these fields continues in 1998.

Murphy's strategy for profitable heavy oil production in Canada is focused on
lowering production costs, which is made possible by the quality of Murphy's
Canadian reserves and use of the best technology. This allows the Company to
weather downturns in pricing, such as that being experienced in early 1998.

                                       15
<PAGE>
 
Productivity at Murphy's heavy oil projects in Canada has been significantly
increased by the Company's ability to leverage new and existing technology.
Murphy co-pioneered the first application of Steam Assisted Gravity Drainage
(SAGD) technology in Saskatchewan by using horizontal wells at its Tangleflags
project (50%). This project has commercially recovered eight million barrels of
oil since 1987 from a quality channel sand that contains 95 million barrels.

New pumping technology has led to commercial primary production from the
Lindbergh field (100%), where the Company has historically conducted only
thermal operations, and peak production rates of 2,500 barrels a day were
achieved during 1997. Also at Lindbergh, piloting of SAGD technology continued
in the thicker sands. This oil is immobile at reservoir temperatures but flows
readily once heated. Although Murphy has not yet developed commercially viable
recovery techniques for current price levels, estimated oil in place of over one
billion barrels encourages further technology development.

Murphy's light oil production in western Canada declined in 1997 due to the
mature nature of the Company's producing property base. As production and income
from Hibernia replace this historically important position in the portfolio, the
Company will accelerate its disposition of these assets.

Murphy's earnings from the Syncrude project increased 18% to $14.3 million.

The midyear start-up of the two U.K. fields will bring production in
northwestern Europe close to 30,000 barrels a day.

- - --------------------------------------------------------------------------------
CORE EXPLORATION AND PRODUCTION: UNITED KINGDOM
- - --------------------------------------------------------------------------------

Murphy's core area of exploration and production in the U.K. is in the North
Sea, where production from the Ninian, "T" Block and Amethyst fields averaged
15,963 barrels of oil equivalent a day in 1997, essentially unchanged from a
year ago. Industry activity in the area remains high. The key to success in the
North Sea is access to acreage, and Murphy's strategy is to continue to
participate actively in licensing rounds, with an emphasis on increasing
ownership interest levels and securing operatorship.

NORTH SEA
Murphy's substantial U.K. North Sea production is set to increase with the
mid-1998 start-up at Mungo/Monan (12.7%). Developed jointly with five other oil
and gas fields as part of the Eastern Trough Area Project (ETAP) integrated
development, Mungo will be produced from a normally unmanned platform, while
Monan will use a subsea system. Both fields will produce to a two-platform
central processing facility.

Jackets for all three ETAP platforms were set and pipelines and other subsea
facilities were installed in 1997. Installation of the topsides will take place
in the spring of 1998, and first oil is expected in mid-1998. Peak gross
production is expected to reach 65,000 barrels of oil and gas liquids a day for
Mungo and Monan combined.

Elsewhere in the North Sea, operatorship of the Ninian field (13.8%) changed in
1997, with a primary emphasis on cost control. As a result, operating costs were
reduced 12 percent. Two new wells were drilled and completed during 1997 at
Ninian, and increased drilling is planned for 1998. On the Ninian satellite
fields, drilling of the second well was in progress at year-end 1997 at Columba
B (5.4%), and drilling of an appraisal well is scheduled for early 1998 at
Columba E (5.8%).

In 1997, the Company completed a successful exploration step-out well at Block
16/17, "T" Block (11.3%), on the north flank of the Tiffany field.

Successful exploratory drilling at Block 16/6b (the Dalmore discovery, 37.5%)
found oil in shallow Paleocene-age sands. Reevaluation of 3-D seismic data
covering this area will occur in 1998, and additional appraisal drilling will be
required before commerciality can be determined.

Murphy acquired interests in an additional 196,000 exploration acres in the U.K.
North Sea in 1997. In "Tranche 1," Blocks 38/9 and 38/10 (40%, Operator) located
on the east end of the Mid North Sea High, 900 kilometers of seismic data will
be evaluated during 1998. Blocks 29/20a and 30/21 (100%, Operator), located on
the western flank of the Central Graben adjacent to the Auk field, were acquired
through an equity swap.

ATLANTIC MARGIN
Murphy's philosophy that a presence in major hydrocarbon basins will lead to
good things is reinforced by an interest in the Schiehallion field (5.9%). A
well drilled in 1994 on acreage acquired as part of the Company's U.K.
exploration efforts confirmed the viability of the emerging Atlantic Margin
play. First production from Schiehallion is expected in mid-1998, and peak gross
production is forecast in excess of 130,000 barrels of oil a day. In 1997,
installation of infield pipelines was completed, while the construction of a
floating production storage and offloading vessel was nearly complete at year
end. Development drilling and completion operations will continue well beyond
first oil.

EXPLORATION AND PRODUCTION: FRONTIER
- - --------------------------------------------------------------------------------

Murphy's management believes the Company has the right geographic spread, the
right risk spread, the right expertise and the right prospects for growing the
Company long-term. As part of developing a strong exploration and production
profile, Murphy has pursued an active and calculated interest in developing
properties, obtaining acreage and entering joint-venture projects in areas
where, though risky, high reward is possible. Exploration and production
activities in these frontier areas are part of management's strategy to position
the Company for substantial future growth.

U.K. ATLANTIC MARGIN
The Atlantic Margin is an area of intense industry activity, and Murphy, because
of its early firsthand understanding of the geology in the Schiehallion field,
has a strong acreage position in this developing frontier. The Company's
strategy of acquiring quality acreage early has resulted in ownership of 24 full
blocks and three partial blocks that encompass a total of 1.39 million acres.
Murphy's average working interest is 25 percent.

In 1997, the Company acquired 25-percent interests in over 650,000 acres,
including U.K. Tranches 36 and 48 and Ireland License 6/97. Murphy's 1998
exploration program is to acquire and evaluate seismic data on this acreage.
Depending on the evaluation, drilling is expected to commence in 1999.

Murphy has also joined a study/bid group with several other oil companies to
evaluate acreage on offer in the Faroe Islands First Licensing Round and in
future U.K. licensing rounds.

[UNITED KINGDOM MAP]

CHINA
In 1996, Murphy participated in a well that discovered oil on Block 04/36 (45%)
in Bohai Bay, northeastern China. The well tested at a combined gross rate in
excess of 6,000 barrels of oil a day from two zones below 11,000 feet. Three
appraisal wells were drilled in 1997, but commerciality is still uncertain.
Murphy is acquiring 3-D seismic data over the discovery area to further define
field limits.

[CHINA MAP]

SOUTH AMERICA
Murphy's production from Block 16 (20%) in Ecuador highlighted the Company's
1997 South American activities. In August, the Southern Production Facilities
went on line, a year ahead of schedule. In addition, eight development oil wells
were drilled, including three horizontal wells, with one completed at multiple
depths. Results from the horizontal wells are very encouraging. Production was
7,802 barrels of oil a day in 1997 compared to 6,005 in 1996. A plan by the
Ecuadoran government to expand pipeline capacity could allow for significant
field production increases.

The Falkland Islands exemplifies Murphy's frontier strategy of "high risk, high
reward" exploration. After acquiring a 25-percent interest in 400,000 acres in
an unexplored sedimentary basin north of the Islands in 1996, the Company
acquired and evaluated 2-D seismic data in 1997. The acreage contains several
large structures and the first of two exploratory wells is scheduled to spud in
mid-1998.

Murphy submitted proposals on three exploration areas to the Brazilian
government during 1997. The Company, as a 100-percent operator, will enter
negotiations on one of the areas during 1998.

SPAIN
In early 1997, Murphy obtained a 35-percent working interest in two adjacent
exploration permits covering 345,000 acres off the northern coast of Spain. In
1998, the Company will acquire 3-D seismic data on the West Fragata permit.

The platform, wells and offshore facilities from the depleted Gaviota field are
utilized as part of Murphy's ALGA gas storage project (18%). ALGA handles
third-party natural gas in consideration for a tariff that covers the operating
cost of the gas storage operations and provides a return on capital invested.
Murphy completed one additional injection/production well and installed
additional onshore compression facilities during 1997.

PHILIPPINES
A Geophysical Survey and Exploration Contract (GSEC) (80%) covering
approximately 3.1 million acres in the northern Sulu Sea has been negotiated and
is awaiting signature by the Philippine president. The GSEC will involve the
acquisition of seismic data, with an option to drill an exploratory well.

PAKISTAN
Murphy is renegotiating the Kharan concession agreement (100%) of 1978, under
which it obtained the rights to explore 6.7 million acres in the province of
Baluchistan in the western part of the country. The acreage has long been held
by force majeure. If negotiations are successful, the Company anticipates
beginning seismic activities in 1998.

ALASKA
Murphy's formerly sizeable holdings in Alaska are now relatively minor, but they
continue to position the Company in an area of renewed interest to the industry.
Unresolved royalty and economic viability issues have delayed the development of
the Sandpiper (58%) and Northstar (2%) projects. During 1997, Murphy acquired a
25-percent interest in 15 leases in Alaskan state waters on which new 3-D
seismic data will be acquired in 1998.

AN OVERVIEW
In 1997, Murphy's worldwide refining, marketing and transportation operations
delivered its best operating performance ever. Compared to 1996, earnings
increased over 300 percent to $56.7 million, and combined throughputs at its
U.S. refineries (Meraux, Louisiana and Superior, Wisconsin) reached record
levels. Improved margins in the U.S. and the U.K. led the way to increased
profitability. Canadian pipeline throughputs increased 25 percent and 21 percent
for Manito and Cactus Lake, respectively.

Throughout its downstream operations, Murphy's commitment to improving the
return on assets through strategic capital investments, lowering operating costs
and appropriate joint ventures is proving effective and successful. The

is volatile, difficult and evolving, but the Company continues to pursue those
activities and initiatives that will overcome these challenges.

Refining capital projects completed in the early and mid-1990s enable Murphy to
process higher sulfur, lower cost crude oil in the U.S. and to produce ultra
low-sulfur distillates in the U.K. As a result of these and other capital
improvements in the Company's refining and marketing facilities, and through the
realignment of operating departments, Murphy has lowered overhead and operating
costs and increased its ability to produce and deliver quality products at
competitive prices.

Refining capital expenditures declined 45 percent in 1997 as the Company's focus
shifted to operational efficiency and reliability. During the same period,
marketing capital expenditures increased by 86 percent, primarily due to
expansion of U.S. retail marketing operations. Two years ago, Murphy announced
plans to build high-volume retail gasoline stations in the parking lots of
Wal-Mart Supercenters and SAM'S Clubs in selected markets in the southeastern
U.S. Since then, 18 stations have been built, including 15 in 1997, under the
Murphy USA(R) brand. The one-stop shopping convenience this endeavor provides
to customers is a tried-and-true facet of European motor fuel marketing. In the
U.S., Murphy is among the first to utilize its integrated downstream assets to
leverage this type of marketing approach.

Following its withdrawal from negotiations to merge with two other companies,
Murphy's U.K. refining and marketing company launched a wide-ranging program to
refocus and further streamline its organization, reduce operating costs and
strengthen its marketing network. A high-pressure distillate hydrotreating unit
completed in 1996 allows the jointly owned Milford Haven refinery (30%) to
supply the U.K. market with cleaner-burning diesel fuel. Successful
implementation of strategic plans and operational changes together with the
closing of a nearby competitor's refinery have helped Murphy's system become one
of the most competitive in the U.K.

Murphy's natural gas marketing division continues to move gas production further
down the delivery system, and in 1997, 40 percent of the Company's daily volume
of natural gas production was sold directly to end users such as utilities. The
Company has made a commitment to carefully planned growth in this area. By
entering into firm transportation agreements and term sales--in effect leasing
pipeline space on an annual basis--Murphy has ensured that pipeline capacity is
available to gather and transport its natural gas production.

Murphy owns interests in five crude oil pipeline systems in western Canada. In
1997, the Murphy-operated Manito and Cactus Lake pipelines were expanded for the
second consecutive year in response to higher heavy oil production levels in
western Saskatchewan and eastern Alberta. With this new capacity, Murphy is able
to meet the increasing demands for reliable and economic transportation in the
areas it serves.

Murphy's U.S. downstream operations posted earnings of $41.3 million, a record
financial performance. The 100,000-barrel-a-day refinery in Meraux, Louisiana
anchors the Company's Gulf Coast market, which serves the southeastern region of
the U.S. The refinery posted impressive throughput results in 1997, with average
crude runs of 101,150 barrels a day, an eight-percent increase over the previous
record achieved in 1996. The efficiency and reliability of this operation--the
refinery recorded a composite 98 percent onstream time in 1997--is the result
of prudent capital investment and careful management.

During 1997, Meraux completed the transition, begun in the early 1990s, from
processing a more expensive light, sweet crude oil to processing a medium, sour
crude oil imported from Latin America. Substantial cost savings resulted from
the refinery's processing over 100,000 barrels a day of the lower cost crude in
1997. Additionally, significant freight savings were realized through the
utilization of large capacity tankers that are offloaded at the Louisiana
Offshore Oil Port (3.2%), which is connected to the Meraux refinery through a
crude oil pipeline owned jointly with another company. Utilization of the
refinery's key process units, including the crude distillation unit and the two
fluid catalytic cracking units, exceeded 100 percent of rated capacities in
1997.

The petroleum products produced at the Meraux refinery are distributed via
pipeline and barges throughout an 11-state marketing area. Murphy's southeastern
distribution system includes 34 terminals, 22 of which are either wholly or
jointly owned by Murphy. The distribution system supplies gasoline to 346 owned
and branded wholesale stations, a net addition of 27 stations over year-end
1996. Products are marketed primarily under the SPUR(R) brand.

The Company's refinery in Superior, Wisconsin processed 33,704 barrels a day of
crude oil in 1997, its best performance since 1977. Taking advantage of the
weakness in the pricing of low gravity crude oil, the refinery processed over
8,100 barrels a day of heavy Canadian asphaltic crude, an increase of more than
15 percent over recent years. Continued reliable operations, stable margins, and
strong light products and asphalt demand supported the increased throughputs.

Murphy's upper-midwestern distribution and marketing system covers a six-state
area. The distribution system includes 21 light products terminals, two of which
are wholly owned by Murphy. This system supplies gasoline to 239 owned and
SPUR(R) branded wholesale stations, a net addition of 31 stations for the
year.

In 1997, a record 1.68 million barrels of asphalt were sold through three
Murphy-owned terminals in the Upper Midwest. Fuel oil and marine diesel fuel
were sold directly into the active Superior/Duluth marine fueling market.

Murphy's U.K. downstream operations earned $9.2 million in 1997, a 48-percent
increase over 1996, largely due to improved margins in retail marketing.

By cutting expenses, closing nonviable service stations, upgrading remaining
outlets and expanding into commercial fuels, the Company's marketing system has
become one of the most competitive in the U.K. It consistently earned profits
during the fierce retail price wars of the past two years, and its recently
developed wide-ranging strategic program strives to ensure that Murphy will
retain its position as a strong competitor.

Murphy has an effective 30-percent interest in the jointly owned Milford Haven
refinery in Wales. Refined products are transported by rail to the Company's
three cost-effective distribution terminals. The Company also receives products
by exchange at seven terminals owned by others.

The refinery continued its reliable operation of past years. A new high-pressure
distillate hydrotreating unit, commissioned in 1996, now enables the refinery to
produce cleaner-burning diesel fuel with a sulfur content of less than 50 parts
per million. The refinery processed a daily average of 26,706 barrels of crude
oil for the Company's account. The refinery's crude runs were reduced from
recent years, primarily due to a monthlong shutdown for planned maintenance.

The Company's retail marketing system in the U.K. includes 396 MURCO branded
stations.

Murphy's five crude oil pipeline systems in western Canada include two that
supply Canadian crude oil to pipelines at the U.S. border. The Murphy-operated
Manito (52.5%) and Cactus Lake (13.1%) pipelines increased throughputs by 25
percent and 21 percent, respectively, over 1996, while the North-Sask pipeline
(36.1%), completed in 1996, exceeded expectations by delivering an average of
15,600 barrels a day into the Manito system.

As previously mentioned, both the Manito and Cactus Lake pipelines were expanded
in 1996 and 1997 to meet the increasing demands for reliable and economic
transportation in western Saskatchewan and eastern Alberta. These successes were
counterbalanced, however, by nearly corresponding throughput reductions on the
U.S.-connected Wascana pipeline (100%), which was exposed to significant new
outside competition from third-party pipelines that commenced operations in
1997.

The Company also operates a fleet of crude oil and natural gas liquid haulers in
Canada. The 70-unit SPUR(R) trucking fleet transported over 48,000 barrels a
day in 1997, and earnings from the trucking operations improved by 30 percent
due to increased utilization.

Overall Canadian downstream operations earned $6.2 million in 1997, essentially
flat with 1996.

In all its operations around the globe, Murphy Oil accepts its responsibility
for environmental stewardship, employee safety and training, emergency
preparedness and community involvement.

- - --------------------------------------------------------------------------------
CORPORATE RESPONSIBILITY
- - --------------------------------------------------------------------------------

The Company's record of responsible corporate citizenship is a tribute to the
hard work, dedication and expertise of its employees and to clear, resolute and
unyielding management practices that emphasize continuous improvement, establish
high standards and encourage employees throughout the Murphy enterprise to
pursue excellence in all facets of their work. The Company has a comprehensive
set of standard operating procedures, a proven system of internal controls and a
published code of conduct for employees and monitors compliance to
environmental, safety, ethical and security policies using internal audit
procedures.

ENVIRONMENTAL PROTECTION AND PERFORMANCE
Since 1990, Murphy has invested more than $200 million in environmental
improvement projects. These projects include an upgrade in equipment and the
construction of a state-of-the-art waste water treatment plant at the Superior,
Wisconsin refinery; a new distillate desulfurizer along with facilities for the
production of reformulated gasoline at the Meraux, Louisiana refinery; and the
construction of a distillate desulfurizer at the Milford Haven refinery in
Wales. In Canada, a voluntary program of running corrosion survey tools on
Company-operated pipelines to monitor line integrity enables Murphy to make
repairs before a problem occurs.

Murphy's investments have produced results. The Superior refinery's waste water
treatment plant effluent is, for most parameters, better than Wisconsin's
standards for drinking water quality. In the U.K., Milford Haven produces
cleaner-burning diesel fuel with a sulfur content of less than 50 parts per
million, more than 90 percent below mandated limits. Overall, Murphy has reduced
air emissions from its refineries by 40 percent in the past eight years.

Murphy's exploration and production operations have adopted cutting-edge,
environmental and safety management policies and procedures that ensure the
efficient production of oil and gas while also achieving high levels of
compliance with all applicable government regulations. In the Gulf of Mexico,
upstream operations have a 99 percent or better compliance record for meeting
required aqueous discharge levels. As part of Murphy's dedication to continue
conscientious environmental and safety practices, the Company is participating
in a voluntary endeavor developed in conjunction with the Minerals Management
Service to implement a Safety and Environmental Management Program. This program
promotes management, training, design, construction, operating and maintenance
initiatives intended to maximize environmental protection and worker safety.

The Company's proactive approach to environmental stewardship is also evident in
its voluntary reclamation activities on U.S. onshore producing properties and in
its active participation in surface reclamation of well sites, roadways and
other facility sites as part of the ongoing Lloydminster Abandonment Program in
western Canada.

EMPLOYEE SAFETY AND TRAINING
Each year, Murphy provides nearly 30,000 hours of training worldwide for safety
and emergency response programs. In addition, the Company offers a myriad of
professional development and personal enrichment classes to employees.

International, national and industry organizations, including the National
Petroleum Refiner's Association, the National Safety Council, the Gas Oil
Pipeline Safety Council, the Canadian OSHA and the Gas Processors Safety Council
have recognized Murphy's achievements with awards and commendations. Those
achievements include seven consecutive years without a lost-time injury in
Murphy's terminal operations. Murphy's exploration and production lost-time
accident incidence rate averaged 0.71 per 200,000 manhours worked over the last
eight years, well below industry norms. In addition, at the request of the
Federal Emergency Management Agency, Murphy's well-regarded emergency response
teams participated in a very successful disaster drill at the Meraux refinery.

COMMUNITY INVOLVEMENT
Murphy's employees and its management team are equal partners in efforts to
contribute positively to the communities in which Murphy's facilities are
located. Murphy and its employees are major contributors to the United Way, and
Murphy is recognized as a pacesetter company in each community where operations
are conducted. Employees volunteer countless hours in numerous educational,
civic and charitable endeavors

                                       28

including school boards, chambers of commerce, youth sports, girl and boy
scouts, mentoring, battered women's shelters, senior citizens' centers, the
American Red Cross and the American Cancer Society. In 1997, Murphy initiated a
Community Spirit Award, presented by President and CEO Claiborne Deming at an
annual awards dinner, to recognize outstanding volunteer efforts on the part of
Murphy employees and local citizens.

Murphy is also a leader in efforts to reward and encourage academic excellence.
The Company recently donated $50,000 toward the purchase of new equipment for
two science labs at the University of Wisconsin-Superior. The Murphy Education
Program is an innovative incentive program in El Dorado, Arkansas, site of the
Company's headquarters. The program awards financial stipends to high school
students demonstrating outstanding academic achievement in Advanced Placement
courses, SAT and ACT standardized testing and the National Merit Scholarship
program. The Company also sponsors scholarship programs in Alberta and
Louisiana.

MANAGEMENT'S DISCUSSION AND ANALYSIS

Results of Operations

Consolidated net income for 1997 was $132.4 million, $2.94 a diluted share,
compared to net income in 1996 of $137.9 million, $3.07 a diluted share. In
1995, the Company lost $118.6 million, $2.65 a diluted share. Results of
operations for the three years ended December 31, 1997 included certain special
items that resulted in a net gain of $.1 million, a nil per share effect, in
1997; a net gain of $22.2 million, $.49 a diluted share, in 1996; and a net
charge of $152 million, $3.39 a diluted share, in 1995. The 1995 special items
included an after-tax charge of $168.4 million, $3.75 a diluted share, from a
write-down of assets determined to be impaired under Statement of Financial
Accounting Standards (SFAS) No. 121. In addition, net income for 1996 and 1995
included earnings from discontinued operations of $11.9 million, $.27 a diluted
share, and $9.3 million, $.20 a diluted share, respectively. Such amounts were
attributable to the activities of the Company's farm, timber and real estate
subsidiary, which was spun off to the Company's shareholders on December 31,
1996, as described in Note B to the consolidated financial statements.

1997 versus 1996 -- Excluding special items, income from continuing operations
totaled $132.3 million, $2.94 a diluted share, in 1997, a Company record. The
results for 1997 represented a $28.5 million improvement compared to income from
continuing operations in 1996, which totaled $103.8 million, $2.31 a diluted
share. Earnings from the Company's exploration and production operations
declined $16.8 million in 1997, primarily due to higher exploration costs.
Increases in crude oil production and natural gas sales led to record
hydrocarbon production in 1997 of 102,272 barrels a day on an energy equivalent
basis. However, lower worldwide crude oil sales prices nearly offset the benefit
of higher production volumes. Income from the Company's refining, marketing and
transportation segment was $56.7 million in 1997, up $42.6 million from 1996.
The improvement occurred primarily in the U.S., where the effects of lower costs
for crude oil and other feedstocks greatly exceeded the decline in sales
realizations for the Company's finished products. The Company's Meraux refinery
continued a trend of processing a lower gravity, higher sulfur crude oil in
1997, and operating results benefited from a favorable cost differential for
this crude oil compared to lighter and sweeter crudes. An improved onstream rate
also helped the Company's U.S. refineries achieve a record level of crude oil
throughputs. Sales of finished products in the U.S. also were at record levels
during 1997. The cost of corporate activities, which includes interest income
and expense and corporate overhead not allocated to operating functions,
decreased $2.7 million in 1997 compared to 1996, primarily due to lower costs of
awards under the Company's incentive plans.

1996 versus 1995 -- Income from continuing operations before special items
totaled $103.8 million in 1996, $2.31 a diluted share, an increase of $79.7
million from the $24.1 million, $.54 a diluted share, generated in 1995. The
favorable results were primarily attributable to a $72.3 million improvement in
earnings from the Company's exploration and production operations. This
improvement was caused by a significant increase in the average sales price for
U.S. natural gas and higher worldwide crude oil sales prices. The Company's
earnings from refining, marketing and transportation operations were up $12.1
million in 1996, with the improvement being primarily a result of crude oil swap
agreements in the U.S. The cost of corporate activities increased $4.7 million
in 1996 due to higher costs of awards under the Company's incentive plans.

In the following table, the Company's results of operations for the three years
ended December 31, 1997 are presented by segment. Special items, which can
obscure underlying trends of operating results and affect comparability between
years, are set out separately. A more detailed review of operating results for
the Company's exploration and production and refining, marketing and
transportation segments follows the table.

Exploration and Production -- Earnings from exploration and production
operations before special items were $85 million in 1997, $101.8 million in 1996
and $29.5 million in 1995. A $24.6 million increase in exploration costs,
primarily in the U.S. Gulf of Mexico and Bohai Bay, China, accounted for the
decline in 1997. While crude oil and liquids production increased eight percent
and natural gas sales increased 22 percent in 1997, these favorable production
volumes were mostly offset by a 13-percent decline in the average worldwide
crude oil sales price. The improvement in 1996 earnings was due to a 59-percent
increase in the average sales price for U.S. natural gas and a 21-percent
increase in the average worldwide crude oil sales price. A seven-percent
reduction in crude oil and liquids production and a 12-percent decline in
natural gas sales volumes provided partial offsets.

The results of operations for oil and gas producing activities for each of the
last three years are shown by major operating area on pages 56 and 57. Daily
production rates and weighted average sales prices are shown on page 59.
A summary of oil and gas revenues is presented in the following table.

  =========================================================

The Company's crude oil and gas liquids production averaged 57,494 barrels a day
in 1997, 53,210 in 1996 and 57,015 in 1995. Crude oil and liquids production in
the U.S. declined eight percent in 1997, with the reduction primarily due to the
sale of onshore producing properties effective July 1, 1996. In 1996, production
was down 15 percent from 1995, again due to the sale of onshore producing
properties in mid-1996. Canadian production rose 12 percent in the current year
compared to a two-percent decline in 1996. Production of heavy oil in Canada
increased 19 percent in 1997 following a nine-percent increase in 1996. The
Company's net interest in production of synthetic crude oil in Canada increased
14 percent in 1997, after declining eight percent in 1996. The increase in net
synthetic oil production in 1997 was due to a three-percent increase in gross
production and a decrease in the net profits royalty rate as a result of lower
crude oil prices during the year. The decrease in net production in 1996 was due
to a higher net profits royalty rate caused by higher oil prices. Before
royalties, the Company's synthetic crude oil production was 10,371 barrels a day
in 1997, 10,036 in 1996 and 10,118 in 1995. The first oil production from the
Company's Hibernia field offshore Newfoundland commenced in the fourth quarter
of 1997 and was averaging 3,800 barrels a day at year-end. The Company's U.K.
oil production increased five percent in 1997 compared to a 12-percent decline
in 1996. Oil production from the Thelma field in the North Sea began in late
1996 and contributed to an 11-percent increase in "T" Block production in 1997.
Oil production at "T" Block was down 14 percent in 1996 as production from
initial fields began to decline. Production from Ninian, the Company's other
major oil-producing North Sea field, declined three percent in 1997 after having
declined 12 percent in 1996. Production in Ecuador increased 30 percent in 1997
following a 14-percent increase in 1996; both increases resulted from new fields
being placed on stream throughout 1996.

Worldwide sales of natural gas averaged 268.7 million cubic feet a day in 1997,
220.6 million in 1996 and 251.7 million in 1995. Sales of natural gas in the
U.S. increased 36 percent in 1997 as new production came on stream from Gulf of
Mexico fields discovered in recent years. An 18-percent decline in U.S. natural
gas sales in 1996 was due to reduced deliverability in certain of the Company's
maturing Gulf of Mexico fields and to the sale of onshore properties in
mid-1996. Natural gas sales in Canada in 1997 were at record levels for the
second straight year, as sales increased four percent in 1997 following a
five-percent increase in 1996. Natural gas sales in the U.K. were down 17
percent in 1997 following a 43-percent increase in 1996. Production of natural
gas in Spain ceased at the end of 1996, after decreasing 33 percent from the
previous year.

[GRAPH - RANGE OF U.S. CRUDE OIL SALES PRICES]

As previously indicated, worldwide crude oil sales prices weakened during 1997
after strengthening during 1996. In the U.S., Murphy's 1997 average monthly
sales prices for crude oil and condensate ranged from $17.23 a barrel to $24.61
a barrel, and averaged $19.43 for the year, four percent below the average 1996
price. In Canada, the average sales price for light oil was $17.74 a barrel in
1997, a decline of 11 percent. Heavy oil prices averaged $10.76 a barrel, down
25 percent from 1996. The average sales price for synthetic crude oil in 1997
was $19.92, off six percent from a year earlier. The sales price for crude oil
from the Hibernia field, which came on stream in the fourth quarter of 1997,
averaged $15.15 a barrel. U.K. sales prices were down 10 percent in 1997 and
averaged $18.89 a barrel. Sales prices in Ecuador averaged $12.17 a barrel in
1997, down 24 percent compared to a year ago. U.S. oil prices increased 22
percent in 1996 compared to 1995 and averaged $20.31 for the year. In Canada,
crude oil prices in 1996 were up 21 percent for light oil, 18 percent for heavy
oil and 23 percent for synthetic oil. Sales prices in the U.K. were up 24
percent in 1996, and prices in Ecuador were up 22 percent. Worldwide crude oil
prices began to decline in the fourth quarter of 1997, and the downward trend
continued into the first quarter of 1998.

Average monthly natural gas sales prices in the U.S. ranged from $1.82 an MCF to
$3.85 during 1997. For the year, U.S. sales prices averaged $2.57 an MCF
compared to $2.60 a

year ago. The average price for natural gas sold in Canada during 1997 increased
23 percent to $1.35 an MCF, while prices in the U.K. increased three percent to
$2.65. Average U.S. natural gas sales prices were up 59 percent in 1996, and
prices were up in Canada and the U.K. by 13 percent and two percent,
respectively, during the same period.

Based on 1997 volumes and deducting taxes at marginal rates, each $1 a barrel
and $.10 an MCF fluctuation in prices would have affected annual exploration and
production earnings by $11.6 million and $6.2 million, respectively. The effect
of these price fluctuations on consolidated net income cannot be measured
because operating results of the Company's refining, marketing and
transportation segment could be affected differently.

Production costs were $164.8 million in 1997, $160.5 million in 1996 and $167.5
million in 1995. These amounts are shown by major operating area on pages 56 and
57. Costs per equivalent barrel of production during the last three years were
as follows.

The decrease in the U.S. cost per equivalent barrel in 1997 was attributable to
the sale of high-cost onshore producing properties in mid-1996. The 1997
increase in Canada, excluding synthetic oil, was due to an increase in heavy oil
production compared to light oil and to higher costs associated with an
expansion of heavy oil thermal recovery projects. The decrease in the cost per
equivalent barrel for Canadian synthetic oil in 1997 was due to higher gross
production volumes and a decrease in royalty barrels caused by lower sales
prices. Based on synthetic oil production before royalties, per-barrel cost
declined two percent in 1997. A lower per-barrel cost in the U.K. in 1997 was
due to a favorable impact from higher production at "T" Block. Higher per-barrel
costs in the U.S. and the U.K. in 1996 were attributable to lower production
volumes. The 1996 increase in Canada, excluding synthetic oil, was due to
production mix, with light oil declining and heavy oil increasing. The increase
in cost for synthetic oil in 1996 was due to lower net production volumes
resulting from the increase in royalty barrels. Costs in Ecuador decreased each
year due to higher production volumes.

Exploration expenses for each of the last three years are shown in total in the
following table, and amounts are reported by major operating area on pages 56
and 57. Certain of the expenses are included in the capital expenditure totals

Depreciation, depletion and amortization for exploration and production
operations totaled $172.4 million in 1997, $147.6 million in 1996 and $182.7
million in 1995. The increase in 1997 was primarily due to higher worldwide
hydrocarbon production, while the decrease in 1996 was partially due to lower
production volumes. In addition, a write-down of assets under SFAS No. 121
during the fourth quarter of 1995 resulted in a reduction in depreciation,
depletion and amortization in 1996 of $12.9 million ($10.5 million after tax).

Refining, Marketing and Transportation -- Earnings from refining, marketing and
transportation operations before special items were $56.7 million in 1997, $14.1
million in 1996 and $2 million in 1995. Operations in the U.S. earned $41.3
million in 1997 compared to income of $1.8 million in 1996, as crude oil and
other refinery feedstock costs declined more than average product realizations.
Operations in the U.S. lost $3.8 million in 1995. Crude oil swap agreements
increased earnings by $5 million in 1997 and $9.2 million in 1996, but reduced
earnings in 1995 by

                                       33
<PAGE>
 
$3.9 million. Operations in the U.K. earned $9.2 million in 1997, $6.2 million
in 1996 and $.3 million in 1995. The improvement in the U.K. in 1997 was also
caused by a larger decline for refining feedstock costs than for sales prices of
finished products. Asset writedowns taken in 1995 under SFAS No. 121 resulted in
a reduction in depreciation, depletion and amortization of $4.6 million ($3.1
million after tax) in 1996. Canadian operations contributed $6.2 million to 1997
earnings compared to $6.1 million in 1996 and $5.5 million in 1995.

Unit margins (sales realizations less costs of crude, other feedstocks, refining
and transportation to point of sale) averaged $1.57 a barrel in the U.S. in
1997, $.25 in 1996 and $.46 in 1995. U.S. product sales were up 12 percent in
1997 following a four-percent increase in 1996. Margins in the U.S. were much
improved during most of 1997 after being under pressure throughout 1996.
Declines in the average costs of crude oil and other feedstocks more than offset
a reduction in average sales realizations until late 1997, when unit margins
experienced a substantial retreat from the mid-year highs. In 1996, the U.S.
margin was down 46 percent compared to 1995.

Unit margins in the U.K. averaged $2.90 a barrel in 1997, $2.08 in 1996 and
$2.26 in 1995. Sales of petroleum products were down 14 percent in 1997
following an eight-percent increase in 1996. Sales through Company-owned and
third-party terminals increased in 1997, but were more than offset by lower
cargo sales caused by a planned turnaround early in the year. The increase in
product sales in 1996 was due to higher cargo sales. Although margins increased
in 1997, the Company's branded outlets still face stiff competition from
supermarket sales of motor fuels.

Based on sales volumes for 1997 and deducting taxes at marginal rates, each $.42
a barrel ($.01 a gallon) fluctuation in unit margins would have affected annual
refining and marketing profits by $17.7 million. The effect of these unit margin
fluctuations on consolidated net income cannot be measured because operating
results of the Company's exploration and production segment could be affected
differently.

Income from purchasing, transporting and reselling crude oil in Canada in 1997
was virtually unchanged as higher pipeline throughputs and better margins on
crude oil trucking operations were offset by lower crude trading margins. The
improvement in earnings in 1996 compared to 1995 was due to increases in crude
trading volumes and margins and higher pipeline throughputs.

Special Items -- Net income for the last three years included the special items
reviewed below; the quarter in which each item occurred is indicated. Certain
other quarterly information is presented on page 38.

 .  Gain on sale of producing properties -- An after-tax gain of $11.5 million
   was recorded in the fourth quarter of 1997 from sale of a Canadian heavy oil
   property, and a $17.7 million gain was recorded in the third quarter of 1996
   from sale of 48 onshore producing oil and gas properties in the U.S.

 .  Impairment of long-lived assets -- After-tax provisions of $3.3 million and
   $12.9 million were recorded in the third and fourth quarters, respectively,
   of 1997, and $168.4 million was recorded in the fourth quarter of 1995 for
   the write-down of assets determined to be impaired under provisions of SFAS
   No. 121 (see Note D to the consolidated financial statements).

 .  Refund and settlement of income tax matters -- A gain of $3.2 million for
   refund of U.K. income taxes was recorded in the third quarter of 1997. A gain
   of $5.1 million for settlement of income tax matters in Canada was recorded
   in the fourth quarter of 1996. A gain of $4.9 million for refund of U.S.
   taxes was included in the third quarter of 1995. Gains for settlement of
   income tax matters in 1995 included $3.2 million and $3.5 million in the
   third and fourth quarters, respectively, for the U.K., and $2 million in the
   fourth quarter for Gabon.

 .  Net recovery (loss) pertaining to 1996 modifications of foreign crude oil
   contracts -- A gain of $1.6 million was recorded in the fourth quarter of
   1997 for a partial recovery of a 1996 loss resulting from modification to a
   crude oil production contract in Ecuador. A net loss of $.6 million was
   recorded in the fourth quarter of 1996 resulting from modifications to
   contracts related to crude oil production in Ecuador and Gabon (See Note O to
   the consolidated financial statements).

 .  Provision for reduction-in-force -- An after-tax provision of $4.2 million
   was recorded in the fourth quarter of 1995 for the cost of enhanced early
   retirement and severance programs.

 .  Adjustment of estimates for self-insured liabilities -- An after-tax gain of
   $7 million was recorded in the first quarter of 1995 from an adjustment of
   amounts previously reserved related to matters for which the Company is
   self-insured.

The income (loss) effects of special items for the three years ended December
31, 1997 are summarized by segment in the following table.

Capital Expenditures

As shown in the selected financial information on page 30, capital expenditures
were $468 million in 1997 compared to $418.1 million in 1996 and $287.2 million
in 1995. These amounts included $84.3 million, $60.5 million and $55.1 million
of exploration expenditures that were expensed.

                                       34
<PAGE>
 
Capital expenditures for exploration and production activities totaled $423.2
million in 1997, 90 percent of the Company's total capital expenditures for the
year. Exploration and production capital expenditures in 1997 included $26.6
million for acquisition of undeveloped leases, $22.2 million for acquisition of
proved oil and gas properties, $135.3 million for exploration activities and
$239.1 million for development projects. Development expenditures included $47.5
million for the Hibernia and Terra Nova oil fields, offshore Newfoundland; $31.3
million and $26 million for the Schiehallion and Mungo/Monan fields,
respectively, offshore U.K.; and $10.4 million for oil fields in Ecuador.
Exploration and production capital expenditures are shown by major operating
area on pages 56 and 57. Amounts shown under "Other" in 1997 included $18.3
million for exploration costs in China, including costs to evaluate a 1996 oil
discovery on Block 04/36 in Bohai Bay. Exploration costs totaling $15.1 million
have been capitalized for Block 04/36 at year-end 1997 pending further
evaluation expected to occur in 1998.

Refining, marketing and transportation expenditures, detailed in the following
table, were $37.5 million in 1997, or eight percent of total capital
expenditures, compared to $42.9 million in 1996 and $53.6 million in 1995.

Refining expenditures in the U.S. were primarily for capital projects necessary
to keep the refineries operating efficiently and within industry standards.
Marketing expenditures included the costs of new stations, primarily on land
leased in the U.S. from Wal-Mart Stores, Inc., and improvements and normal
replacements at existing stations and terminals.

Cash Flows

Cash provided by continuing operations was $401.8 million in 1997, $472.5
million in 1996 and $309.9 million in 1995. Special items increased cash flow
from operations by $3.8 million in 1997 and $14.7 million in 1995, but reduced
cash by $12.8 million in 1996. Changes in operating working capital other than
cash and cash equivalents required cash of $72.4 million in 1997, provided cash
of $77.1 million in 1996 and required cash of $36.6 million in 1995. Cash
provided by continuing operations was further reduced by expenditures for
refinery turnarounds and abandonment of oil and gas properties totaling $14.4
million in 1997, $10.8 million in 1996 and $13.8 million in 1995.

Cash proceeds from property sales were $43.8 million in 1997, $55.5 million in
1996 and $8.3 million in 1995. Additional borrowings under nonrecourse debt
arrangements provided $6.4 million of cash in 1997, $23.1 million in 1996 and
$59.5 million in 1995. Other borrowings also provided $9.7 million of cash in
1997.

Capital expenditures required $468 million of cash in 1997, $418.1 million in
1996 and $287.2 million in 1995. Other significant cash outlays during the three
years included $17.3 million in 1997, $11.4 million in 1996 and $35.6 million in
1995 for debt repayment. Cash used for dividends to stockholders was $60.6
million in 1997 and $58.3 million in both 1996 and 1995.

Financial Condition

Year-end working capital totaled $48.3 million in 1997, $56.1 million in 1996
and $87.4 million in 1995. The current level of working capital does not fully
reflect the Company's liquidity position, as the relatively low historical costs
assigned to inventories under LIFO accounting were $76 million below current
costs at December 31, 1997. Cash and equivalents at the end of 1997 totaled
$24.3 million compared to $109.7 million a year ago and $60.9 million at
year-end 1995.

Long-term obligations increased $4.1 million during 1997 to $205.9 million at
year-end, 16 percent of total capital employed, and included $177.5 million of
nonrecourse debt incurred in connection with the acquisition and development of
proved properties. Long-term obligations totaled $201.8 million at the end of
1996 compared to $193.1 million at year-end 1995. Stockholders' equity was $1.1
billion at the end of 1997 compared to $1 billion a year ago and $1.1 billion at
the end of 1995. The decrease in 1996 was caused by the spin-off of the
Company's farm, timber and real estate subsidiary to stockholders at year-end. A
summary of transactions in the equity accounts is presented on page 43.

The primary sources of the Company's liquidity are internally generated funds,
access to outside financing and working capital. The Company relies on
internally generated funds to finance the major portion of its capital and other
expenditures, but maintains lines of credit with banks and borrows as necessary
to meet spending requirements. Current financing

                                       35
<PAGE>
 
arrangements are set forth in Note E to the consolidated financial statements.
The Company does not anticipate any problem in meeting future requirements for
funds.

The Company had commitments of $228 million for capital projects in progress at
December 31, 1997, including $89 million related to a one-third interest in a
five-year contract for a semisubmersible drilling rig capable of drilling in
6,000 feet of water. Delivery of the rig is scheduled for 1999.

Environmental

The Company's worldwide operations are subject to numerous laws and regulations
intended to protect the environment and/or impose remedial obligations. In
addition, the Company is involved in personal injury and property damage claims,
allegedly caused by exposure to or by the release or disposal of materials
manufactured or used in the Company's operations. The Company operates or has
previously operated certain sites or facilities, including refineries, oil and
gas fields, service stations, and terminals, for which known or potential
obligations for environmental remediation exist.

Under the Company's accounting policies, liabilities for environmental
obligations are recorded when such obligations are probable and the cost can be
reasonably estimated. If there is a range of reasonably estimated costs, the
most likely amount will be recorded, or if no amount is most likely, the minimum
of the range is used. Recorded liabilities are reviewed quarterly and adjusted
as needed. Actual cash expenditures often occur one or more years after
recognition of the liabilities.

The Company's reserve for remedial obligations, which is included in "Deferred
Credits and Other Liabilities" in the Consolidated Balance Sheets, contains
certain amounts that are based on anticipated regulatory approval for proposed
remediation of former refinery waste sites. If regulatory authorities require
more costly alternatives than the proposed processes, future expenditures could
exceed the amount reserved by up to an estimated $3 million.

The Company has received notices from the U.S. Environmental Protection Agency
(EPA) that it is a Potentially Responsible Party (PRP) at seven Superfund sites
and has been assigned responsibility by defendants at another Superfund site.
The potential total cost to all parties to perform necessary remedial work at
these sites may be substantial. Based on currently available information, the
Company has reason to believe that it is no longer considered a PRP by the EPA
at five of these sites and that it is a "de minimus" party as to ultimate
responsibility at the other three sites. The Company does not expect that its
related remedial costs will be material to its financial condition or its
results of operations, and it has provided no reserve for remediation costs on
Superfund sites. Additional information may become known in the future that
would alter this assessment, including any requirement to bear a pro rata share
of costs attributable to nonparticipating PRPs or indications of additional
responsibility by the Company.

Although the Company is not aware of any environmental matters that might have a
material effect on its financial condition, there is the possibility that
additional expenditures could be required at currently unidentified sites, and
new or revised regulatory requirements could necessitate additional expenditures
at known sites. Such expenditures could materially affect the results of
operations in a future period.

Certain liabilities for environmentally related obligations and prior
environmental expenditures are expected to be recovered by the Company from
other sources, primarily environmental funds maintained by the various states.
Since no assurance can be given that recoveries from other sources will occur,
the Company has not recorded a benefit for these potential recoveries at
December 31, 1997.

The Company's refineries also incur costs to handle and dispose of hazardous
wastes and other chemical substances on a recurring basis. These costs are
generally expensed as incurred and amounted to $3.2 million in 1997.

In addition to remediation and other recurring expenditures, Murphy commits a
portion of its capital expenditure program for compliance with environmental
laws and regulations. Such capital expenditures were approximately $25 million
in 1997 and are expected to be $33 million in 1998.

Other Matters

 .  Impact of inflation - General inflation was moderate during the last 
   three years in most countries where the Company operates; however, the
   Company's revenues and capital and operating costs are influenced to a larger
   extent by specific price changes in the oil and gas and allied industries
   than by changes in general inflation. Crude oil and petroleum product prices
   generally reflect the balance between supply and demand, with crude oil
   prices being particularly sensitive to OPEC production levels and/or
   attitudes of traders concerning supply and demand in the near future. Natural
   gas prices are affected by supply and demand, which to a significant extent
   is weather-related, and by the fact that delivery of supplies is generally
   restricted to specific geographical areas. Higher crude oil and natural gas
   sales prices over most of the last two years have led to upward pressure on
   amounts paid by the Company for goods and services, particularly in offshore
   operations.

 .  Accounting matters - The Financial Accounting Standards Board (FASB) issued
   SFAS No. 130, Reporting Comprehensive Income, in June 1997. The statement
   requires the Company to report both comprehensive income and net income for
   all periods presented beginning with the quarter ending March 31, 1998.
   Through 1997, the Company's only item of other comprehensive income as
   defined by this statement has been foreign currency translation adjustments.
   The following table shows the Company's pro forma comprehensive income for
   the three years ended December 31, 1997.

   The FASB also issued SFAS No. 131, Disclosures about Segments of an
   Enterprise and Related Information, in June 1997. This statement will alter
   the Company's disclosures about its operating segments beginning with the
   results for the year ending December 31, 1998 and for each period thereafter,
   with restated comparative disclosures for earlier periods. Although this
   statement does not amend any existing accounting procedures, it requires
   disclosures about an enterprise's components for which separate financial
   information is available and regularly used by the chief operating decision
   maker in allocating resources and assessing performance. Although the Company
   has not fully determined the effects that the new statement will have on its
   1998 consolidated financial statements, it expects to provide certain
   additional segment information for revenues, expenses and assets on a
   geographical basis.

   During 1997, the Securities and Exchange Commission adopted amendments to
   Regulation S-K that will require expanded disclosures concerning a broad
   range of market sensitive instruments, including debt and equity securities
   and derivative instruments, beginning with the Company's 1998 Annual Report.
   Specifically, the new rules will require the Company to make disclosure
   outside of the consolidated financial statements of both quantitative and
   qualitative information concerning the market risks posed by risk-sensitive
   instruments. As described in Notes A and J, the Company makes limited use of
   derivative instruments to hedge specific market risks. The Company has not
   determined which of several acceptable methods it will use to present the
   required quantitative and qualitative disclosures.

 .  Year 2000 issues - The Company has assessed its electronic operating systems
   to identify those that are not Year 2000 compliant and is in the process of
   developing an implementation plan for noncompliant systems. Although the
   Company cannot predict with any degree of certainty the total amount that
   will be spent to address this issue, the assessment indicates that up to $5
   million of expense could be incurred through 1999 to modify systems to be
   Year 2000 compliant. Costs incurred and expensed in 1997 for the Year 2000
   issue were insignificant. The Company is also in the process of communicating
   with significant vendors and business partners to determine its risks
   relative to these third parties' systems on which the Company relies.
   Although the Company expects to have all of its major systems compliant by
   year-end 1999, there can be no assurance that the Company will not be
   adversely affected by internal or third-party operating systems that
   encounter Year 2000 problems.

 .  Other - The Company's use of derivative financial instruments and the effects
   of exchange rate fluctuations on net income are reviewed in Notes J and M,
   respectively, to the consolidated financial statements.

Outlook

In planning for 1998, prices for the Company's products remain uncertain.
Worldwide crude oil sales prices declined sharply in the fourth quarter of 1997,
primarily caused by increasing oil production from OPEC producers and a
softening of worldwide oil demand due to the economic downturn in Asia. The
downward trend in oil prices has continued in early 1998, as the Company's
average worldwide oil prices were as much as $4 a barrel below the average price
for the fourth quarter of 1997. The lower oil prices will exert downward
pressure on the Company's operating results in early 1998. In such an
environment, constant reassessment of spending plans is required. The Company's
capital expenditure budget for 1998 was prepared during the fall of 1997 and
provides for expenditures of $539 million. A major portion of this amount, $440
million or 82 percent, is allocated for exploration and production.
Geographically, about 37 percent of the exploration and production budget is
designated for the U.S.; 35 percent for Canada, including $77 million for
further development of the Hibernia and Terra Nova oil fields; 19 percent for
the U.K., including $44 million for development costs related to the
Schiehallion and Mungo/Monan oil fields; four percent for continuing development
of oil fields in Ecuador; and the remaining five percent for other overseas
operations. Refining, marketing and transportation capital expenditures for 1998
are budgeted at $97 million, including $81 million in the U.S. and $8 million
each in the U.K. and Canada. Capital and other expenditures are under constant
review, and these budgeted amounts may be adjusted to reflect changes in
estimated cash flow.

Forward-Looking Statements

This Annual Report includes statements of the Company's expectations,
intentions, plans and beliefs that are forward-looking and are dependent on
certain events, risks and uncertainties that may be outside of the Company's
control. These forward-looking statements are made in reliance upon the safe
harbor provisions of the Private Securities Litigation Reform Act of 1995.
Actual results and developments could differ materially from those expressed or
implied by such statements due to a number of factors including those described
in the context of such forward-looking statements as well as those contained in
the Company's January 15, 1997 Form 8-K on file with the U.S. Securities and
Exchange Commission.

 REPORT OF MANAGEMENT
- - --------------------------------------------------------------------------------

Preparation and integrity of the accompanying consolidated financial statements
and other financial data are the responsibility of management. The statements
were prepared in conformity with generally accepted accounting principles
appropriate in the circumstances and include some amounts based on informed
estimates and judgments, with consideration given to materiality.

Management is also responsible for maintaining a system of internal accounting
controls designed to provide reasonable, but not absolute, assurance that
financial information is objective and reliable by ensuring that all
transactions are properly recorded in the Company's accounts and records,
written policies and procedures are followed and assets are safeguarded. The
system is also supported by careful selection and training of qualified
personnel. When establishing and maintaining such a system, judgment is required
to weigh relative costs against expected benefits. The Company's audit staff
independently and systematically evaluates and formally reports on the adequacy
and effectiveness of the internal control system.

Our independent auditors, KPMG Peat Marwick LLP, have audited the consolidated
financial statements. Their audit was conducted in accordance with generally
accepted auditing standards and provides an independent opinion about the fair
presentation of the consolidated financial statements. When performing their
audit, KPMG Peat Marwick LLP considers the Company's internal control structure
to the extent they deem necessary to issue their opinion on the financial
statements. The Board of Directors appoints the independent auditors;
ratification of the appointment is solicited annually from the shareholders.

The Board of Directors appoints an Audit Committee annually to perform an
oversight role for the financial statements. This Committee is composed solely
of directors who are not employees of the Company. The Committee meets
periodically with representatives of management, the Company's audit staff and
the independent auditors to review the Company's internal controls, the quality
of its financial reporting, and the scope and results of audits. The independent
auditors and the Company's audit staff have unrestricted access to the
Committee, without management's presence, to discuss audit findings and other
financial matters.

 INDEPENDENT AUDITORS' REPORT
- - --------------------------------------------------------------------------------

The Board of Directors and Stockholders
Murphy Oil Corporation:

We have audited the accompanying consolidated balance sheets of Murphy Oil
Corporation and Consolidated Subsidiaries as of December 31, 1997 and 1996, and
the related consolidated statements of income, stockholders' equity and cash
flows for each of the years in the three-year period ended December 31, 1997.
These consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards 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. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Murphy Oil
Corporation and Consolidated Subsidiaries as of December 31, 1997 and 1996, and
the results of their operations and their cash flows for each of the years in
the three-year period ended December 31, 1997, in conformity with generally
accepted accounting principles.

As discussed in Note C to the consolidated financial statements, in 1995 the
Company adopted the provisions of Financial Accounting Standards Board's
Statement of Financial Accounting Standards No. 121, Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
- - --------------------------------------------------------------------------------

NOTE A - SIGNIFICANT ACCOUNTING POLICIES

NATURE OF BUSINESS - Murphy Oil Corporation is an international oil and gas
company that conducts business through various operating subsidiaries. The
Company produces oil and natural gas in the U.S., Canada, the U.K. North Sea and
Ecuador, and conducts exploration activities in numerous countries. The Company
has an interest in a Canadian synthetic crude oil operation, the world's
largest, and operates two oil refineries in the U.S. and shares ownership in a
U.K. refinery. Murphy markets petroleum products under various brand names in
the U.S., the U.K. and Canada and trades and transports crude oil in Canada.

PRINCIPLES OF CONSOLIDATION - The consolidated financial statements include the
accounts of Murphy Oil Corporation and all majority-owned subsidiaries.
Investments in affiliates in which the Company has 20- to 50-percent ownership
are accounted for by the equity method. Other investments are generally carried
at cost. All significant intercompany accounts and transactions have been
eliminated.

CASH EQUIVALENTS - Short-term investments (which include government securities
or other securities with government securities as collateral) that have a
maturity of three months or less from the date of purchase are classified as
cash equivalents.

INVENTORIES - Inventories of crude oil and refined products are generally valued
at cost applied on a last-in, first-out (LIFO) basis, which in the aggregate is
lower than market. Materials and supplies are valued at the lower of average
cost or estimated value.

PROPERTY, PLANT AND EQUIPMENT - The Company uses the successful efforts method
to account for exploration and development expenditures. Leasehold acquisition
costs are capitalized. If proved reserves are found on an undeveloped property,
leasehold cost is transferred to proved properties. Significant undeveloped
leases are reviewed periodically and a valuation allowance is provided for any
estimated decline in value. Cost of other undeveloped leases is expensed over
the estimated average life of the leases. Cost of exploratory drilling is
initially capitalized but is subsequently expensed if proved reserves are not
found. Other exploratory costs are charged to expense as incurred. Development
costs, including unsuccessful development wells, are capitalized.

In 1995 the Company adopted Statement of Financial Accounting Standards (SFAS)
No. 121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed Of. Under SFAS No. 121, oil and gas properties are
evaluated by field for potential impairment; other long-lived assets are
evaluated on a specific asset basis or in groups of similar assets, as
applicable. An impairment is recognized when the undiscounted estimated future
net cash flows of an evaluated asset are less than the carrying value of the
asset.

Depreciation and depletion of producing oil and gas properties are provided
under the unit-of-production method. Unit rates are computed for unamortized
development costs using developed reserves and for unamortized leasehold costs
using proved reserves. Estimated dismantlement, abandonment and site restoration
costs, net of salvage value, are considered in determining depreciation and
depletion. Refining and marketing facilities are depreciated using the composite
straight-line method. Other properties are depreciated by individual unit on the
straight-line method. 

Gains and losses on disposals or retirements that are significant or include an
entire depreciable or depletable property unit are included in income. Costs of
dismantling oil and gas production facilities and site restoration are charged
against the related reserve. All other dispositions, retirements or abandonments
are reflected in accumulated depreciation, depletion and amortization.

Provisions for refinery turnarounds are charged to expense monthly. Costs
incurred are changed against the reserve. All other maintenance and repairs are
expensed. Renewals and betterments are capitalized.

ENVIRONMENTAL LIABILITIES - A provision for environmental obligations is charged
to expense when the Company's liability for an environmental assessment and/or
cleanup is probable and the cost can be reasonably estimated. Related
expenditures are charged against the reserve. Environmental remediation
liabilities have not been discounted for the time value of future expected
payments. Environmental expenditures that have future economic benefit are
capitalized.

INCOME TAXES - The Company accounts for income taxes using the asset and
liability method. Under this method, income taxes are provided for amounts
currently payable, and for amounts deferred as tax assets and liabilities based
on differences between the financial statement carrying amounts and the tax
bases of existing assets and liabilities and measured using the enacted tax
rates that are assumed will be in effect when the differences reverse. Provision
for U.K. petroleum revenue taxes is based on the estimated effective tax rate
over the life of certain U.K. properties.

FOREIGN CURRENCY - Local currency is the functional currency used for recording
operations in Canada and Spain and the majority of activities in the U.K. The
U.S. dollar is the functional currency used to record all other operations.
Gains or losses from translating foreign functional currency into U.S. dollars
are included in "Currency Translation Adjustments" in "Stockholders' Equity."
Exchange gains or losses from transactions in a currency other than the
functional currency are included in income.

DERIVATIVE INSTRUMENTS - Derivative instruments are used by the Company on a
limited basis to manage well-defined risks related to interest rates, foreign
currency exchange rates and commodity prices. Instruments that reduce the
exposure of assets, liabilities or anticipated transactions to price, currency
or interest rate risks are accounted for as hedges. Gains and losses on
derivatives that cease to qualify as hedges are recognized in income or expense.
The Company does not hold any derivatives for trading purposes. Net cash amounts
paid or received 

                                      44
<PAGE>
 
on interest rate swaps are recognized as an adjustment of interest expense over
the life of the swap contract. Gains or losses on settlement of crude oil swaps
are included in costs in the periods that the hedged oil purchases occur. A loss
is recognized if the estimated cost of the future crude oil purchases, including
projected settlement costs of these swap contracts, exceeds the estimated net
realizable value of the related finished products. Gains or losses on foreign
exchange contracts are recognized in income or as adjustments to the carrying
amounts when the hedged transactions occur.

EXCISE TAXES ON REFINED PRODUCTS - Taxes collected on the sales of refined
products and remitted to governmental agencies are not included in revenues or
costs and expenses.

NET INCOME PER COMMON SHARE - Basic income per Common share is computed by
dividing net income for each reporting period by the weighted average number of
Common shares outstanding during the period. Diluted income per Common share is
computed by dividing net income for each reporting period by the weighted
average number of Common shares outstanding during the period plus the effects
of potentially dilutive Common shares.

USE OF ESTIMATES - In the preparation of financial statements of the Company in
conformity with generally accepted accounting principles, management has made a
number of estimates and assumptions related to the reporting of assets,
liabilities, revenues and expenses and the disclosure of contingent assets and
liabilities. Actual results may differ from the estimates.

NOTE B - DISCONTINUED OPERATIONS

On December 31, 1996, Murphy completed a tax-free spin-off to its stockholders
of all the common stock of its wholly owned farm, timber and real estate
subsidiary, Deltic Farm & Timber Co, Inc. (reincorporated as "Deltic Timber
Corporation"). The spin-off resulted in a net charge of $172,561,000 to
"Retained Earnings" in 1996. Farm, timber and real estate activities have been
accounted for as discontinued operations. Selected operating results for these
activities, presented as net amounts in the Consolidated Statements of Income,
were as follows.

NOTE C - ACCOUNTING CHANGES

Effective December 31, 1997, the Company adopted SFAS No. 128, Earnings per
Share. In accordance with SFAS No. 128, the Company has restated income per
Common share computations for the first three quarters of 1997 and for all prior
periods presented. SFAS No. 128 requires that earnings per share be presented on
both a basic (which assumes no dilution for potential stock issuances) and a
diluted (assumes dilutive effects of potential stock issuances) basis. Adoption
of this statement did not significantly change income per Common share as
previously reported.

Effective October 1, 1995, the Company adopted SFAS No. 121, Accounting for 
the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of.
The effects of this accounting change are discussed in Note D.

*Includes $17,084 in 1997 and $17,989 in 1996 related to administrative assets
 and support equipment.


In 1997 and 1995, the Company recorded noncash charges of $28,056,000 and
$198,988,000, respectively, for impairment of certain long-lived assets in
accordance with SFAS No. 121. After related income tax benefits, these write-
downs reduced net income by $16,224,000 in 1997, $.36 a diluted share, and
$168,367,000 in 1995, $3.75 a diluted share. The 1997 impairment charges related
to certain investments in Canadian heavy oil fields that were not adequately
supported by proven reserves and three natural gas fields in the Gulf of Mexico
that depleted earlier than anticipated. The 1995 charge was taken upon adoption
of SFAS No. 121 and resulted from management's expectation of a continuation of
the low-price environment for crude oil, natural gas and petroleum products that
existed throughout most of 1995; the write-down included certain oil and gas
assets in Ecuador, the U.K. North Sea and the U.S. Gulf of Mexico and U.K.
refining and marketing assets. The carrying values for assets determined to be
impaired were adjusted to fair values based on estimated future net cash flows
for such assets, discounted at a market rate of interest.

NOTE E - FINANCING ARRANGEMENTS

At December 31, 1997, the Company had a committed credit facility with a major
banking consortium for an equivalent US $300,000,000 for a combination of U.S.
dollar and Canadian dollar borrowings, of which US $7,500,000 was outstanding at
that date. In addition, the Company had committed facilities of US $120,564,000
with major banks that are subject to drawdown based on the availability of loan
guarantees from the Canadian government. Depending on the credit facility,
borrowings bear interest at prime or varying cost of fund options. Facility fees
are due at varying rates on certain of the commitments. The facilities expire at
dates ranging from 1998 through 2002. At December 31, 1997 and 1996, U.S. dollar
and Canadian dollar commercial paper and bankers' acceptances totaling an
equivalent US $118,834,000 and US $114,496,000, supported by bank credit
facilities, were classified as nonrecourse debt.

                                      45
<PAGE>
In addition, the Company had other lines of credit with banks at December 31,
1997 totaling an equivalent US $129,578,000 for a combination of U.S. dollar and
Canadian dollar borrowings. At December 31, 1997, US $2,175,000 was outstanding
under these lines, which could be withdrawn at any time.

At year-end 1997, the Company had a shelf registration on file with the
Securities and Exchange Commission that would permit the offer and sale of
$250,000,000 in debt securities. No securities had been issued as of December
31, 1997.

The nonrecourse guaranteed credit facilities were arranged to finance
expenditures for the Hibernia oil field. Subject to certain conditions and
limitations, the Canadian government has unconditionally guaranteed repayment of
amounts drawn under/supported by the facilities to lenders having qualifying
Participation Certificates. The Company has borrowed the maximum available under
the Primary Guarantee Facility at December 31, 1997. The amount guaranteed
declines quarterly beginning two years after cumulative production reaches 25
million barrels, which is now projected to occur near the end of 1998. No
guaranteed financing is available after January 1, 2016. A guarantee fee of .5
percent is payable annually in arrears to the Canadian government. Quarterly
repayment, projected to begin in 2001, is based on the greater of 30 percent of
the field's after-tax free cash flow or an eight-year amortization. Since the
Company intends to refinance outstanding debt under the Primary Guarantee
Facility, the first debt payment is reflected as becoming due in 2001.

The 6.25-percent promissory note of Cdn $37,972,000 (US $28,517,000 at a hedged
exchange rate) is payable to the province of Alberta and is secured by a
debenture, which mortgages the Company's interest in the Syncrude project and
its production therefrom. The province's right to recover the principal and
interest on the note is limited to the mortgaged property and funds available
from that production. This borrowing has been classified as long-term at
December 31, 1997, since the Company intends to refinance this obligation under
an existing committed credit facility during 1998.

================================================================================

In management's judgment, the net deferred tax assets in the preceding table
will more likely than not be realized as reductions of future taxable income or
by utilizing available tax planning strategies. The valuation allowance for
deferred tax assets relates primarily to tax assets arising in foreign tax
jurisdictions, and in the judgment of management, these tax assets are not
likely to be realized. The valuation allowance increased $13,619,000 in 1997
after decreasing $988,000 in 1996; the change in each year offset the change in
certain deferred tax assets. Any subsequent reductions of the valuation
allowance will be reported as reductions of income tax expense assuming no
offsetting change in the deferred tax asset.

The Company has not recorded a deferred tax liability of $25,700,000 related to
undistributed earnings of certain foreign subsidiaries at December 31, 1997,
because the earnings are considered permanently invested.

Income tax returns are subject to audit by the Internal Revenue Service and tax
authorities of other countries. In 1997, 1996 and 1995, the Company recorded
benefits to income of $3,163,000, $5,120,000 and $13,603,000, respectively, from
refunds and settlements of various U.S. and foreign tax issues primarily related
to prior years. The Company believes that adequate accruals have been made for
unsettled issues.

NOTE H - INCENTIVE PLANS

The Company's 1992 Stock Incentive Plan (the Plan) permits annual awards of
shares of the Company's Common Stock to executives and other key employees.
Under the Plan, the Executive Compensation and Nominating Committee (the
Committee) is authorized to grant: (1) stock options (nonqualified or
incentive), (2) stock appreciation rights (SAR) and (3) restricted stock awards.
Total annual grants may not exceed .5 percent of shares outstanding at the end
of the preceding year; any allowed shares not granted may be awarded in future
years. The Company uses APB Opinion No. 25 to account for stock-based
compensation plans. Accordingly, costs of options and restricted stock are
accrued over the vesting/performance periods and are adjusted for subsequent
changes in fair market value of the shares. Compensation cost charged against
income for stock-based plans was $2,026,000 in 1997, $5,566,000 in 1996 and
$222,000 in 1995; outstanding awards were not significantly modified in the last
three years. Had compensation cost of the Company's stock-based plans been based
on the fair value of the instruments at the grant dates using the provisions of
SFAS No. 123, Accounting for Stock-Based Compensation, the Company's net income
and earnings per share would be the following pro forma amounts.

- - --------------------------------------------------------------------------------

The pro forma effects on net income in the preceding table may not be
representative of the pro forma effects on net income of future years because
the SFAS No. 123 provisions used in these calculations were only applied to
options and restricted stock granted after 1994.

STOCK OPTIONS - For each option granted under the Plan, the Committee fixes the
option price at no less than fair market value (FMV) on the date of the grant
and fixes the option term at no more than 10 years from such date. Each
option granted to date has had a 10-year term, has been nonqualified, and has
had an option price equal to grant-date FMV except for certain 1997 grants with
option prices above grant-date FMV. One-half of each grant may be exercised
after two years and the remainder after three years. At exercise, a grantee may
pay cash for shares, or alternatively, not remit cash and only receive shares
equal to the inherent value of options exercised on that date. The number of
outstanding options at January 1, 1997 and the related option prices 

                                      47

were adjusted to preserve the existing economic values of the options at the
time of the Deltic spin-off.

The pro forma net income calculations in the preceding table reflect the
following weighted-average grant-date fair values of options granted in 1997,
1996 and 1995; these have been estimated by using the Black-Scholes option-
pricing model and the assumptions as shown.

SAR - SAR may be granted in conjunction with or independent of stock options;
the Committee determines when SAR may be exercised and the price. No SAR have
been granted.

RESTRICTED STOCK - Since 1992, shares of restricted stock have been granted in
alternate years. Each grant will vest if the Company achieves specific financial
objectives at the end of a five-year performance period. Additional shares may
be awarded if objectives are exceeded, but some or all shares may be forfeited
if objectives are not met. During the performance period, a grantee may vote and
receive dividends on the shares, but shares are subject to transfer restrictions
and are all or partially forfeited if a grantee terminates, depending on the
reason. The Company may reimburse a grantee up to 50 percent of the award value
for personal income tax liability on stock awarded. For the pro forma net income
calculation, the fair value per share of restricted stock granted in 1996 was
$42.44, the grant-date market price of the stock. On December 31, 1996, the
performance period ended for shares granted in 1992; based on financial
objectives achieved, 50 percent of eligible shares were awarded and the
remainder were forfeited. The number of restricted shares outstanding at January
1, 1997 was adjusted to preserve the existing economic value of the stock at the
time of the Deltic spin-off. Changes in restricted stock outstanding were as
follows.

CASH AWARDS - The Committee also administers the Company's incentive
compensation plans, which provide for annual or periodic cash awards to
officers, directors and key employees if the Company achieves specific financial
objectives. Compensation expense of $3,894,000, $3,100,000 and $400,000 was
recorded in 1997, 1996 and 1995, respectively, for these plans.

EMPLOYEE STOCK PURCHASE PLAN (ESPP) - In 1997, the Company's shareholders
approved the ESPP, under which 50,000 shares of the Company's Common Stock could
be sold to employees. Each quarter, an eligible U.S. employee may elect to
withhold up to 10 percent of his or her salary to purchase shares of the
Company's stock at a price equal to 90 percent of the fair value of the stock as
of the first day of the quarter or, if appropriate, the last business day prior
to such date. The ESPP will terminate at the earlier of the date that all 50,000
shares have been sold or June 30, 2002. In 1997, 4,326 shares of the Company's
stock were sold under the ESPP at $44.44 a share, and at year-end 45,674 shares
remained available for sale. Compensation costs related to the ESPP were
immaterial.

NOTE I - EMPLOYEE AND RETIREE BENEFITS

RETIREMENT PLANS - The Company has noncontributory defined benefit retirement
plans that cover substantially all employees. Benefits are based on years of
service and final-pay or career-average-pay formulas as defined by the plans.
The Company also has a nonqualified supplemental plan for directors and
supplemental plans that provide benefits to employees whose defined benefits
under their retirement plan formula cannot be fully funded because of

                                       48
<PAGE>
statutory limitations on the amount of benefits that may be paid from qualified
plans. As part of a reduction-in-force program, special termination benefits
were offered certain U.S. employees in 1995; a curtailment gain resulted from
reduced future service cost for employees accepting the offer.

Retirement expense (credit) and its components for 1997, 1996 and 1995 are shown
in the following table.

Amounts contributed to U.S. funded plans are actuarially determined and are at
least the minimum required by the Employee Retirement Income Security Act of
1974. Amounts contributed to non-U.S. plans are based on local laws. The
supplemental plans are unfunded. Accumulated benefits in excess of assets in
these plans were $6,381,000 in 1997 and $5,501,000 in 1996; these amounts have
been netted in the following table, which sets forth the combined funded status
of plans and amounts recognized in the Consolidated Balance Sheets.

THRIFT PLANS - Most employees of the Company in the U.S. and Canada may
participate in thrift plans by allotting up to a specified percentage of their
base pay. The Company matches contributions at a stated percentage of each
employee's allotment based on length of participation in the plans. Company
contributions to these plans were $3,076,000 in 1997, $2,784,000 in 1996 and
$2,952,000 in 1995, including $190,000 in 1996 and $157,000 in 1995 that were
included in "Income from Discontinued Operations" in the Consolidated Statements
of Income.

POSTRETIREMENT BENEFITS - The Company sponsors plans that provide health care
and life insurance benefits for most retired U.S. employees. Costs are accrued
for these plans during the service lives of covered employees. Retirees
contribute a portion of the cost of health care benefits; the Company
contributes the remainder. The Company pays premiums for life insurance
coverage, arranged through an insurance company. The health care plan is self-
funded on a pay-as-you-go basis. The Company has the right to modify the
benefits and/or costsharing provisions.

Based on actuarial computations, postretirement expense and its components for
1997, 1996 and 1995 were as follows.

Postretirement expense included in "Income from Discontinued Operations" in the
Consolidated Statements of Income was $433,000 in 1996 and $466,000 in 1995.

A summary follows of postretirement benefit obligations recorded at December 31,
1997 and 1996. Calculation of the amount of accumulated unfunded postretirement
benefit obligations (APBO) was based on discount rates of 7.00 percent in 1997
and 7.50 percent in 1996. Accrued APBO obligations were included in "Deferred
Credits and Other Liabilities" in the Consolidated Balance Sheets.

================================================================================

In determining the APBO at December 31, 1997, health care inflation cost was
assumed to increase at an annual rate of 7.5 percent, gradually decreasing to
4.5 percent in 2002 and thereafter. A one-percent increase in the assumed health
care cost trend would increase the 1997 postretirement benefit expense by 7.2
percent and the APBO at December 31, 1997 by 6.5 percent.

NOTE J - FINANCIAL INSTRUMENTS

DERIVATIVE INSTRUMENTS - Murphy utilizes derivative instruments on a limited
basis to manage risks related to interest rates, foreign currency exchange rates
and commodity prices. The use of derivative instruments is closely monitored by
the Company's senior management, and all such transactions are designed to
address certain risk-management objectives. The Company does not hold any
derivatives for trading purposes, and it does not use derivatives with leveraged
features. Derivative instruments are traded either with creditworthy major
financial institutions or over national exchanges.

At December 31, 1997, the Company had interest rate swaps agreements with
notional amounts totaling $100,000,000 that serve to convert an equal amount of
variable rate long-term debt to fixed rates. The swaps mature in 2002 and 2004
and have a weighted-average fixed interest rate of 6.46 percent. No interest
rate swaps were outstanding at December 31, 1996. Using the accrual/settlement
method of accounting, the net amount to be received or paid on a quarterly basis
under the swap agreements is accrued as part of "Interest Expense" in the
Consolidated Income Statement. Although the Company has never terminated an
interest rate swap prior to maturity, if it did, any cash paid or received as
settlement would be deferred and recognized as an adjustment to interest expense
over the shorter of the remaining life of the debt or the remaining contractual
life of the swap.

At December 31, 1997, the Company had a forward foreign currency exchange
contract that serves to fix the U.S. dollar cost for Canadian dollar nonrecourse
debt associated with the Company's Syncrude project. The currency exchange
contract matures in December 1998, at which time the Company will pay US
$28,517,000 to acquire the Canadian dollars needed to meet the payment of Cdn
$37,970,000. The Company accounts for the unrealized difference between the
contract exchange rate and the actual period-ending exchange rate on the
Consolidated Balance Sheet as an adjustment to "Nonrecourse Debt of a
Subsidiary" with the offset to "Currency Translation Adjustments." When the
contract is settled, any adjustment to the difference previously recorded will
be included in the same accounts.

The Company previously used crude oil swap agreements to reduce a portion of the
financial exposure of its U.S. refineries to crude oil price movements.
Unrealized gains or losses on such swap contracts were generally deferred and
recognized in connection with the associated crude oil purchase. If conditions
indicated that the market price of finished products would not allow for
recovery of the costs of the finished products, including any unrealized loss on
the crude oil swap, a liability was provided for the nonrecoverable portion of
the unrealized swap loss. The final swap matured in the third quarter of 1997.
The Company recorded operating results associated with crude oil swaps in "Crude
Oil, Products and Related Operating Expenses" in the Consolidated Statements of
Income. For 1997, 1996 and 1995, the after-tax results of crude oil swaps were
gains (losses) of $5,041,000, $9,209,000 and $(3,900,000), respectively.

FAIR VALUE - The following table presents the carrying amounts and estimated
fair values of financial instruments held by the Company at December 31, 1997
and 1996. The fair value of a financial instrument is the amount at which the
instrument could be exchanged in a current transaction between willing parties.
The table excludes cash and cash equivalents, trade accounts receivable,
investments and noncurrent receivables, trade accounts payable, and accrued
expenses, all of which had fair values approximating carrying amounts.

The carrying amounts of financial liabilities in the preceding table are
included in the Consolidated Balance Sheets under "Current Maturities of Long-
Term Obligations," "Notes Payable," "Notes Payable and Capitalized Lease
Obligations" and "Nonrecourse Debt of a Subsidiary." The following methods and
assumptions 
                                      50
<PAGE>

were used to estimate the fair value of each class of financial instruments for
which it is practicable to estimate that value.

 . Current and long-term debt - The fair value is estimated based on current
  rates offered the Company for debt of the same maturities.

 . Interest rate and crude oil swaps - The fair value is an estimate of the
  amount, based on quotes from counterparties, that the Company would receive
  (pay) at the reporting date to cancel the contracts.

 . Financial guarantees and letters of credit - The fair value, which represents
  fees associated with obtaining the instruments, was nominal.

CREDIT RISKS - The Company's primary credit risks are associated with trade
accounts receivable, cash equivalents and derivative instruments. Trade
receivables arise mainly from sales of crude oil, natural gas and petroleum
products to a large number of customers in the U.S., Canada and the U.K. The
credit history and financial condition of potential customers are reviewed
before credit is extended, security is obtained when considered appropriate
based on a potential customer's financial condition, and routine follow-up
evaluations are made. The combination of these evaluations and the large number
of customers tend to limit the risk of credit concentration to an acceptable
level. Cash equivalents are placed with several major financial institutions;
this limits the Company's exposure to credit risk. The Company controls the
credit risks on derivatives through credit approvals and monitoring procedures
and believes such risks are minimal, as counterparties to the transactions are
major financial institutions.

NOTE K - STOCKHOLDER RIGHTS PLAN

The Company's Stockholder Rights Plan provides for each Common stockholder to
receive a dividend of one Right for each share of the Company's Common Stock
held. The Rights will expire on December 6, 1999, unless earlier redeemed or
exchanged. The Rights will detach from the Common Stock and become exercisable
following a specified period of time after the first public announcement that a
person or group of affiliated or associated persons (other than certain persons)
has become the beneficial owner of 15 percent or more of the Company's Common
Stock. The Rights have certain antitakeover effects and will cause substantial
dilution to a person or group that attempts to acquire the Company without
conditioning the offer on a substantial number of Rights being acquired. The
Rights are not intended to prevent a takeover, but rather are designed to
enhance the ability of the Board of Directors to negotiate with an acquiror on
behalf of all shareholders. Other terms of the Rights are set forth in, and the
foregoing description is qualified in its entirety by, the Rights Agreement
between the Company and Harris Trust Company of New York, as Rights Agent.

NOTE L - EARNINGS PER SHARE

A reconciliation of the weighted-average shares outstanding for computation of
basic and diluted income per Common share for the three years ended December 31,
1997 follows. No difference existed between net income used in computing basic
and diluted income per Common share for these years.

NOTE M - OTHER FINANCIAL INFORMATION

INVENTORIES - Inventories valued at cost under the LIFO method totaled
$82,709,000 and $63,783,000 at December 31, 1997 and 1996, respectively. These
amounts were $76,008,000, and $120,290,000 respectively, less than such
inventories would have been valued using the FIFO method.

FOREIGN CURRENCY - Cumulative translation gains and losses are included in
"Stockholders' Equity." At December 31, 1997, components of the net cumulative
gain of $891,000 were gains (losses) of $37,320,000 for pounds sterling,
$(37,031,000) for Canadian dollars and $602,000 for other currencies.
Comparability of net income was not significantly affected by exchange rate
fluctuations in 1997, 1996 or 1995. Net gains (losses) from foreign currency
transactions included in the Consolidated Statements of Income were $200,000 in
1997, $(175,000) in 1996 and $82,000 in 1995.

CASH FLOW DISCLOSURES - Cash income taxes paid, net of refunds, were
$86,962,000, $51,983,000 and $24,638,000 in 1997, 1996 and 1995. Interest paid,

NOTE N - COMMITMENTS

The Company leases land, service stations and other facilities under operating
leases. Future minimum rental commitments under noncancellable operating leases
are not material. Commitments for capital expenditures were approximately
$228,000,000 at December 31, 1997, including $89,000,000 related to a one-third
interest in a 


                                      51
<PAGE>

five-year contract for a semisubmersible drilling rig capable of drilling in
6,000 feet of water. Delivery of the rig is scheduled for 1999.

NOTE O - CONTINGENCIES

The Company's operations and earnings have been and may be affected by various
forms of governmental action both in the U.S. and throughout the world. Examples
of such governmental action include, but are by no means limited to: tax
increases and retroactive tax claims; restrictions on production; import and
export controls; price controls; currency controls; allocation of supplies of
crude oil and petroleum products and other goods; expropriation of property;
restrictions and preferences affecting issuance of oil and gas or mineral
leases; laws and regulations intended for the protection and/or remediation of
the environment; promotion of safety; governmental support for other forms of
energy; and laws and regulations affecting the Company's relationships with
employees, suppliers, customers, stockholders and others. Because governmental
actions are often motivated by political considerations, may be taken without
full consideration of their consequences, and may be taken in response to
actions of other governments, it is not practical to attempt to predict the
likelihood of such actions, the form the actions may take or the effect such
actions may have on the Company.

FOREIGN CRUDE OIL CONTRACTS - In August 1996, the Ecuadoran government notified
the Company that its contractual arrangement for production of crude oil in
Ecuador must be modified to give the government a larger share of future oil
revenues. As a result, the Company's risk-service contract was replaced by a
production-sharing contract effective January 1, 1997. While the state oil
company, PetroEcuador, acknowledged that amounts were owed under the former
contract and indicated its intention to pay, the Company considered the
circumstances surrounding the contract replacement and recorded an $8,876,000
provision for doubtful accounts at December 31, 1996. Based on amounts collected
in 1997, the Company determined that a portion of the allowance for doubtful
accounts was no longer required and recognized income of $1,642,000 in 1997. Any
collections of the remaining $7,234,000 receivable will be recognized as income
as received.

In late 1996, the Company negotiated a settlement of abandonment obligations
with other joint owners of former oil properties in Gabon. As a result of this
settlement, the Company recorded a net gain of $8,201,000 in 1996 to adjust for
the dismantlement reserve no longer required.

ENVIRONMENTAL MATTERS - The Company's environmental contingencies are reviewed
in Management's Discussion and Analysis under the section entitled
"Environmental" on page 36.

OTHER MATTERS - The Company and its subsidiaries are engaged in a number of
legal proceedings, all of which the Company considers routine and incidental to
its business and none of which is considered material. In the normal course of
its business activities, the Company is required under certain contracts with
various governmental authorities and others to provide letters of credit that
may be drawn upon if the Company fails to perform under those contracts. At
December 31, 1997, the Company had contingent liabilities of $15,400,000 on
outstanding letters of credit and $14,000,000 under certain financial
guarantees.

NOTE P - BUSINESS SEGMENTS

Information about business segments and geographic operations is summarized in
the following tables. Excise taxes on petroleum products of $679,953,000,
$550,116,000 and $521,250,000 for the years 1997, 1996 and 1995 were excluded
from revenues and costs and expenses. Intracompany and affiliated company
transfers are at market prices. Companies accounted for by the equity method are
primarily engaged in the transportation of crude oil and petroleum products.

SUPPLEMENTAL OIL AND GAS INFORMATION (UNAUDITED)
- - --------------------------------------------------------------------------------

The following schedules are presented in accordance with Statement of Financial
Accounting Standards No. 69 (SFAS No. 69), Disclosures about Oil and Gas
Producing Activities, to provide users with a common base for preparing
estimates of future cash flows and comparing reserves among companies.
Additional background information follows concerning four of the schedules.

SCHEDULES 1 AND 2 - ESTIMATED NET PROVED OIL AND NATURAL GAS RESERVES
Reserves of crude oil, condensate, and natural gas liquids and natural gas are
estimated by the Company's engineers and adjusted to reflect contractual
arrangements and royalty rates in effect at each year-end. Many assumptions and
judgmental decisions are required to estimate reserves. Reported quantities are
subject to future revisions, some of which may be substantial, as additional
information becomes available. Such additional knowledge may result from:
reservoir performance, new geological and geophysical data, additional drilling,
technological advancements, price changes and other economic factors.

Regulations of the U.S. Securities and Exchange Commission define proved
reserves as those volumes of crude oil, condensate, and natural gas liquids and
natural gas that geological and engineering data demonstrate with reasonable
certainty are recoverable from known reservoirs under existing economic and
operating conditions. Proved developed reserves are volumes expected to be
recovered through existing wells with existing equipment and operating methods.
Proved undeveloped reserves are volumes expected to be recovered as a result of
additional investments for drilling new wells on acreage offsetting productive
units, recompleting existing wells, and/or installing facilities to collect and
transport volumes produced.

Production quantities shown are net volumes withdrawn from reservoirs. These may
differ from sales quantities due to inventory changes and, especially in the
case of natural gas, volumes consumed for fuel and/or shrinkage from extraction
of natural gas liquids. Such differences were insignificant for crude oil and
liquids, but amounted to approximately 2.4 billion cubic feet in 1997, 1.5
billion in 1996 and .5 billion in 1995 for natural gas.

Synthetic oil reserves in Canada are attributable to Murphy's share, after
deducting estimated net profit royalty, of the currently producing leases in the
Syncrude project. Additional reserves will be added as development progresses on
other Syncrude leases.

The Company has no proved reserves attributable to either long-term supply
agreements with foreign governments or investees accounted for by the equity
method.

SCHEDULE 4 - RESULTS OF OPERATIONS FOR OIL AND GAS PRODUCING ACTIVITIES
Results of operations from exploration and production activities by geographic
area are reported on this schedule as if these activities were a separate
corporate entity rather than part of an operation that also refines crude oil
and sells refined products. Results of oil and gas producing activities include
certain special items that are reviewed in Management's Discussion and Analysis
(see page 34), and should be considered in conjunction with the Company's
overall performance.

SCHEDULE 6 - STANDARDIZED MEASURE OF DISCOUNTED FUTURE NET CASH FLOWS RELATING
TO PROVED OIL AND GAS RESERVES 
SFAS No. 69 requires calculation of future net cash flows using a 10-percent
annual discount factor and year-end (1997 and 1996) prices, costs and statutory
tax rates, except for known future changes such as contracted prices and
legislated tax rates. Future net cash flows from the Company's interest in
synthetic oil are excluded.

The reported value of proved reserves is not necessarily indicative of either
fair market value or present value of future cash flows because prices, costs
and governmental policies do not remain static; appropriate discount rates may
vary; and extensive judgment is required to estimate the timing of production.
Other logical assumptions would likely have resulted in significantly different
amounts. Average crude oil prices at year-end 1997 used for this calculation
were $16.27 a barrel for the U.S., $15.68 for Canadian light, $6.28 for Canadian
heavy, $14.47 for Canadian offshore, $15.83 for the U.K. and $11.79 for Ecuador.
Average natural gas prices were $2.71 an MCF for the U.S., $1.18 for Canada and
$2.60 for the U.K. Oil and natural gas prices have declined sharply in early
1998.

Schedule 6 also presents the principal reasons for change in the standardized
measure of discounted future net cash flows for each of the three years ended
December 31, 1997.

                                  UNDERTAKINGS

     To be incorporated by reference into Form S-8 Registration Statements No.
2-82818, 2-86749, 2-86760, and 333-27407, and Form S-3 Registration Statement
No. 33-55161.

     The undersigned registrant hereby undertakes:

     (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:

         (i)    To include any prospectus required by section 10(a)(3) of the
Securities Act of 1933;

         (ii)   To reflect in the prospectus any facts or events arising after
the effective date of the registration statement (or the most recent post-
effective amendment thereof) which, individually or in the aggregate, represents
a fundamental change in the information set forth in the registration statement;

         (iii)  To include any material information with respect to the plan of
distribution not previously disclosed in the registration statement or any
material change to such information in the registration statement;

     (2) That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

     (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

     The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

     The undersigned registrant hereby undertakes:

     (1) To deliver or cause to be delivered with the prospectus to each
employee to whom the prospectus is sent or given a copy of the registrant's
annual report to stockholders for its last fiscal year, unless such employee
otherwise has received a copy of such report, in which case the registrant shall
state in the prospectus that it will promptly furnish, without charge, a copy of
such report on written request of the employee.  If the last fiscal year of the
registrant has ended within 120 days prior to the use of the prospectus, the
annual report of the registrant for the preceding

                                  Ex. 99.1-1
<PAGE>
 
fiscal year may be so delivered, but within such 120 day period the annual
report for the last fiscal year will be furnished to each such employee.

     (2) To transmit or cause to be transmitted to all employees participating
in the plan who do not otherwise receive such material as stockholders of the
registrant, at the time and in the manner such material is sent to its
stockholders, copies of all reports, proxy statements and other communications
distributed to its stockholders generally.

     Where interests in a plan are registered herewith, the undersigned
registrant and plan hereby undertake to transmit or cause to be transmitted
promptly, without charge, to any participant in the plan who makes a written
request, a copy of the then latest annual report of the plan filed pursuant to
section 15(d) of the Securities Exchange Act of 1934 (Form 11-K).  If such
report is filed separately on Form 11-K, such form shall be delivered upon
written request.  If such report is filed as a part of the registrant's annual
report on Form 10-K, that entire report (excluding exhibits) shall be delivered
upon written request.  If such report is filed as a part of the registrant's
annual report to stockholders delivered pursuant to paragraph (1) or (2) of this
undertaking, additional delivery shall not be required.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable.  In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
