Registration Statement of which this Prospectus is a part, for each $1,000
principal amount of its outstanding 10 1/4% Senior Subordinated Notes Due 2008
(the "Old Notes"), of which an aggregate of $150,000,000 in principal amount is
outstanding as of July   , 1998. (COVER CONTINUED ON PAGE II.)
                            ------------------------
 
THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
 EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE
   SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION
     PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY

                            ------------------------
 
    Interest on the New Notes will be paid in cash at a rate of 10 1/4% per
annum on each February 1 and August 1, commencing February 1, 1999. The New
Notes may be redeemed at the option of the Company, in whole or in part, at any

accrued interest, declining ratably to 100% of their principal amount, plus

                 THE DATE OF THIS PROSPECTUS IS         , 1998.
<PAGE>
    The New Notes will be general unsecured obligations of the Company entitled
to the benefits of the Indenture (as defined herein). The New Notes will be
subordinated in right of payment to all existing and future Senior Debt, will
rank PARI PASSU in right of payment with the Old Notes and all other senior
indebtedness of the Company, and will rank senior in right of payment to all
other subordinated indebtedness of the Company. The Old Notes and the New Notes
(together, the "Notes") will be subordinated in right of payment to all existing
and future Senior Debt, will rank PARI PASSU in right of payment to all other
Senior Indebtedness and will rank senior in right of payment to all other
subordinated indebtedness of the Subsidiary Guarantors. As of March 31, 1998,
after giving pro forma effect to the Worland Field Acquisition (as defined
herein) and the related financing, the Company would have had, on a consolidated
basis, $3.9 million of Senior Debt (exclusive of $75.0 million of unused
commitments under the Credit Facility), all of which would rank senior to the
Notes, and the Company would have had no senior subordinated debt outstanding
(exclusive of the Notes) and the Subsidiary Guarantors would have had no
indebtedness outstanding other than the guarantees of the Credit Facility and
the Subsidiary Guarantees. The form and terms of the New Notes are identical in
all material respects to the form and terms of the Old Notes except that the New
Notes have been registered under the Securities Act. Any Old Notes not tendered
and accepted in the Exchange Offer will remain outstanding and will be entitled
to all the rights and preferences and will be subject to the limitations
applicable thereto under the Indenture. Following consummation of the Exchange
Offer, the holders of the Old Notes will continue to be subject to the existing
restrictions upon transfer thereof and the Company will have no further
obligation to such holders to provide for the registration under the Securities
Act of the Old Notes held by them. Following the completion of the Exchange
Offer, none of the Notes will be entitled to the contingent increase in interest
rate provided pursuant to the Old Notes. The Exchange Offer is being made
pursuant to the terms of the registration rights agreement (the "Registration
Rights Agreement") entered into between the Company and Chase Securities Inc.
(the "Initial Purchaser") pursuant to the terms of the Purchase Agreement dated
July 21, 1998 between the Company and the Initial Purchases. The New Notes and
the Old Notes are collectively referred to herein as the "Notes." See "The
Exchange Offer--Purpose and Effect of the Exchange Offer."
 
    Based on interpretations by the staff of the Securities and Exchange
Commission (the "Commission") set forth in no-action letters issued to third
parties, the Company believes the New Notes issued pursuant to the Exchange
Offer in exchange for Old Notes may be offered for resale, resold and otherwise
transferred by any holder thereof (other than broker-dealers, as set forth
below, and any such holder that is an "affiliate" of the Company within the
meaning of Rule 405 under the Securities Act) without compliance with the
registration and prospectus delivery provisions of the Securities Act, provided
that such New Notes are acquired in the ordinary course of such holder's
business and that such holder has no arrangement or understanding with any
person to participate in the distribution of such New Notes. Any holder who
tenders in the Exchange Offer with the intention to participate, or for the
purpose of participating, in a distribution of the New Notes or who is an
affiliate of the Company may not rely upon such interpretations by the staff of
the Commission and, in the absence of an exemption therefrom, must comply with
the registration and prospectus delivery requirements of the Securities Act in
connection with any secondary resale transaction. Holders of Old Notes wishing
to accept the Exchange offer must represent to the Company in the Letter of
Transmittal that such conditions have been met.
 
    Each broker-dealer (other than an affiliate of the Company) that receives
New Notes for its own account pursuant to the Exchange Offer must acknowledge
that it will deliver a prospectus meeting the requirements of the Securities Act
in connection with any resale of such New Notes. The Letter of Transmittal
states that by so acknowledging and by delivering a prospectus, a broker-dealer
will not be deemed to admit that it is an "underwriter" within the meaning of
the Securities Act. This Prospectus, as it may be amended or supplemented from
time to time, may be used by a broker-dealer in connection with resales of New
Notes received in exchange for Old Notes where such Old Notes were acquired by
such broker-dealer as a result of market-making activities or other trading
activities. The Company has agreed that, for a period of 180 days after the last
date Old Notes are accepted for exchange pursuant to the Exchange Offer (the
"Exchange Date"), it will make this Prospectus available to any broker-dealer
for use in connection with any such resale. See "Plan of Distribution." Any
broker-dealer who is an affiliate of the Company may not rely on such no-action
letters and must comply with the registration and prospectus delivery
requirements of the Securities Act in connection with a secondary resale
transaction.

                                  THE COMPANY
 
    Continental is engaged in the development, exploitation, exploration and
acquisition of oil and gas reserves, primarily in the Rocky Mountains and the
Mid-Continent and, to a lesser extent, in the Gulf Coast region of Texas and
Louisiana. In addition to its exploration, development and production
activities, the Company owns and operates 1,000 miles of natural gas pipelines,
five gas gathering systems and three gas processing plants in its operating
areas. The Company also engages in natural gas marketing, gas pipeline
construction and saltwater disposal. Capitalizing on its growth through the
drill-bit and its acquisition strategy, on a pro forma basis the Company
increased its estimated proved reserves from 12.7 MMBoe in 1993 to 64.9 MMBoe in
1997, and increased its annual production from 2.0 MMBoe in 1993 to 5.2 MMBoe in
1997. At December 31, 1997, on a pro forma basis, approximately 80% of the
Company's estimated proved reserves were oil and approximately 63% of its total
estimated reserves were classified as proved developed. At March 31, 1998, on a
pro forma basis, the Company had interests in 1,390 producing wells of which it
operated 1,112. In fiscal year 1997, the Company had pro forma revenues and
EBITDA of $120.2 million and $61.0 million, respectively. During the first three
months of 1998, the Company had pro forma revenues and EBITDA of $25.4 million
and $11.2 million, respectively, reflecting lower prevailing oil and gas prices.
 
    The Company's Rocky Mountain activities are concentrated in the Williston
Basin of North Dakota, South Dakota and Montana and in the Big Horn Basin of
Wyoming. The Company's operations in the Williston Basin are focused on the
Cedar Hills Field which the Company believes is, potentially, one of the largest
onshore discoveries in the lower 48 states since 1971. The Cedar Hills Field
represented approximately 45% of the PV-10 attributable to the Company's
estimated proved reserves at December 31, 1997, on a pro forma basis. In the
Williston Basin, the Company owns approximately 470,000 net leasehold acres and
has interests in 322 gross (252 net) wells, has identified 105 potential
drilling locations and conducts both primary drilling and enhanced recovery
operations. The Company recently expanded its activities into the Big Horn Basin
through the acquisition of producing and non-producing properties in the Worland
Field. The Company currently owns approximately 35,000 net leasehold acres in
the Big Horn Basin and has interests in 292 gross (125 net) producing wells
which, on a pro forma basis, represented approximately 10% of the PV-10
attributable to the Company's estimated proved reserves at December 31, 1997. In
the Big Horn Basin the Company has identified 164 potential drilling locations
which represent significant opportunities.
 
    The Company's Mid-Continent activities are conducted primarily in the
Anadarko Basin of western Oklahoma, southwestern Kansas and the Texas Panhandle
and, to a lesser extent, in the Arkoma Basin of southeastern Oklahoma, and in
southern Illinois. At December 31, 1997 the Company's Anadarko Basin properties
represented approximately 95% of the PV-10 attributable to the Company's
estimated proved reserves in the Mid-Continent and approximately 36% of the
Company's total estimated proved reserves, on a pro forma basis. In the Anadarko
Basin the Company owns approximately 57,000 net leasehold acres, has interests
in 658 gross (408 net) producing wells and has identified 11 potential drilling
locations. The Company also owns leasehold interests and expects to expand its
exploration activities in the Arkoma Basin and Gulf Coast region of Texas and
Louisiana.

BUSINESS STRENGTHS
 
    The Company believes that it has certain strengths that provide it with
significant competitive advantages, including the following:
 
    PROVEN GROWTH RECORD.  Continental has demonstrated consistent growth
through a balanced program of development and exploratory drilling and
acquisitions. During the five years ended December 31, 1997, the Company
increased proved reserves by 411%, production by 161% and EBITDA by 414%, on a
pro forma basis.
 
    SUBSTANTIAL DEVELOPMENT DRILLING INVENTORY.  The Company has identified over
275 potential development drilling locations based on geological and geophysical
evaluations. As of March 31, 1998, on a pro forma basis, the Company held
approximately 590,000 net acres, of which approximately 64% were classified as
undeveloped. Management believes that its current acreage holdings could support
five to seven years of drilling activities based upon oil and gas prices in
effect at March 31, 1998.
 
    LONG-LIFE NATURE OF RESERVES.  Continental's producing reserves are
primarily characterized by low rate, relatively stable, mature production that
is subject to gradual decline rates. As a result of the long-lived nature of its
properties, the Company has relatively low reinvestment requirements to maintain
reserve quantities, primary and secondary production levels and reserve values.
At December 31, 1997, on a pro forma basis, the Company's proved reserve life
index was 12.5 years.
 
    SUCCESSFUL DRILLING RECORD.  The Company has maintained a successful
drilling record. In the blanket type Red River B formation of the Williston
Basin, the Company's success rate during the three years ended December 31, 1997
was 92%, while in its other areas, the success rate was 65%, resulting in an
overall success rate of 85%. During the five years ended December 31, 1997 the
Company participated in 253 gross (175 net) wells which resulted in the addition
of 24.9 MMBoe at an average cost of $5.50 per Boe.
 
    SIGNIFICANT OPERATIONAL CONTROL.  Approximately 94% of the Company's pro
forma PV-10 at December 31, 1997 was attributable to wells operated by the
Company, giving Continental significant control over the amount and timing of
capital expenditures and production, operating and marketing activities.
 
    TECHNOLOGICAL LEADERSHIP.  The Company has demonstrated significant
expertise in the rapidly evolving technologies of 3-D seismic evaluation and
precision horizontal drilling, and is among the few companies in North America
to successfully utilize high pressure air injection ("HPAI") enhanced recovery
technology on a large scale. Through the combination of precision horizontal
drilling and HPAI secondary recovery technology, the Company has significantly
enhanced the recoverable reserves underlying its oil and gas properties. Since
its inception, Continental has experienced a 300% to 400% increase in
recoverable reserves through use of these technologies.
 
    EXPERIENCED AND COMMITTED MANAGEMENT.  Continental's senior management team
has extensive experience in the oil and gas industry. The Chief Executive
Officer, Harold Hamm, began his career in the oil and gas industry in 1967 and
has grown Continental's revenues to $120.2 million in 1997, on a pro forma
basis. Seven senior officers have an average of 20 years of oil and gas industry
experience. Additionally, the Company's technical staff, which includes ten
petroleum engineers and ten geoscientists, has an average of over 20 years
experience in the industry.
 
BUSINESS STRATEGY
 
    The Company's strategy is to increase reserves, production and cash flow.
Key elements of the Company's strategy are:
 
    MAINTAIN A BALANCED DRILLING PROGRAM.  Continental has historically grown
through a balanced program of exploratory and development drilling and
acquisitions. Commencing in 1993, approximately 70%
 
                                       2
<PAGE>
of wells drilled have been development wells and the Company expects a similar
balance from its current drilling inventory. Approximately 85% of current
inventory is focused on further expansion and development of oil projects in the
Rocky Mountains, while the remainder is focused on natural gas projects in the
Mid-Continent and the Gulf Coast. The Company currently has an inventory of 275
potential development drilling locations. The drilling budget for 1998 is $36.0
million, which is expected to fund the drilling of 48 gross (33.6 net) wells;
and for the three months ended March 31, 1998, the Company expended $12.9
million in drilling 15 gross (9.4 net) wells.
 
    MAXIMIZE RESERVE RECOVERY.  The Company routinely uses advanced technology
such as precision horizontal drilling, 3-D seismic technology and HPAI
technology in its operations. Management believes that its expertise in
horizontal drilling and its record of over 20 years of successfully utilizing
HPAI technology provide the Company with a distinct competitive advantage for
its development and exploration program. Since its inception, Continental has
drilled 130 and participated in another 27 horizontal wells. The Company
currently operates four of the eight active HPAI projects in North America and
six traditional water-flood projects, and is evaluating three additional
waterflood and two additional HPAI projects, as well as approximately 185
workovers of existing wells. The Company intends to continue to apply HPAI
technology to its Cedar Hills Field and West Medicine Pole Hills properties to
maximize oil recoveries. Based on its experience in operating HPAI projects,
Continental believes that the use of HPAI technology in secondary recovery
operations, coupled with precision horizontal drilling, will increase total oil
recovery by 300% to 400% over average primary production, or by 50% over
secondary recovery utilizing traditional waterflooding.
 
    ACQUISITIONS OF OIL AND GAS RESERVES.  The Company focuses on acquisitions
that (i) complement its existing exploration program, (ii) provide opportunities
to utilize the Company's technological advantages, (iii) have the potential for
enhanced recovery activities, and/or (iv) provide new core areas for the
Company's operations.
 
    MAINTAIN LOW COST STRUCTURE.  The management team is committed to a low cost
structure in order to maximize cash flow and earnings. Continental has achieved
low operating and general and administrative costs through economies of scale
and geographic focus. Finding costs are expected to decline over time as the
benefits of secondary recovery methods are realized.
 
    EXPAND GAS GATHERING AND MARKETING.  Continental's extensive gas gathering
infrastructure and its regional natural gas marketing operations are integral to
the Company's low cost structure and high revenues per unit of gas production.
The Company intends to expand its gas gathering systems to further improve the
rate of return on drilling and development activities and to increase the
throughput of natural gas from third parties. The gas marketing operations
provide a ready market for increased production, allowing the Company to
increase its marketing of third-party gas as well as its own production.
 
RECENT EVENTS
 
    WORLAND FIELD ACQUISITION.  The Company recently completed an $86.5 million
acquisition of producing and non-producing oil and gas properties in the Worland
Field of the Big Horn Basin in northern Wyoming, effective June 1, 1998 (the
"Worland Field Acquisition"). Effective the same date, the Company sold an
undivided 50% interest in the Worland Field properties (excluding inventory and
certain items of equipment) to the Company's principal shareholder for $42.6
million. See "Certain Relationships and Related Transactions." All references to
the Worland Field Acquisition and the related properties refer only to the
Company's interest in the Worland Field properties after giving effect to the
sale to the Company's principal shareholder.
 
    Continental's interests in the Worland Field include 35,000 net leasehold
acres, on which are located 292 producing wells, 272 of which are operated by
the Company. As of December 31, 1997, the estimated net proved reserves
attributable to the Company's interest in the Worland Field properties were 32.0
 
                                       3
<PAGE>
MMBoe, with an estimated PV-10 of $25.4 million. The Worland Field properties
include six identified exploratory prospects for further extension of the known
producing reservoirs. The Worland Field Acquisition materially increases the
Company's proved reserves and provides additional exploration and exploitation
opportunities in areas similar to and near Continental's Williston Basin
operating area.
 
    CEDAR HILLS FIELD TRANSACTION.  On May 15, 1998, the Company entered into a
definitive agreement whereby, effective December 1, 1998, Continental and an
unrelated joint interest owner in the Cedar Hills Field will exchange undivided
interests so that the Company will ultimately own working interests ranging from
90% to 92% in approximately 65,000 gross (59,000 net) leasehold acres in the
northern half of the Cedar Hills Field and the joint interest owner will acquire
a substantial portion of the Company's interests in the southern half of the
Cedar Hills Field. As a result, the Company will enhance its ability to unitize
all interests in the northern half of the Cedar Hills Field which is necessary
in order for the Company to initiate its planned HPAI enhanced recovery
operations.

                                    other nominee and who wishes to tender such Old Notes in
                                    the Exchange Offer should contact such registered holder
                                    promptly and instruct such registered holder to tender

                                    completed stock power from the registered holder. The
                                    transfer of registered ownership may take considerable
                                    time and may not be able to be completed prior to the
                                    Expiration Date. See "The Exchange Offer--Terms of the
                                    Exchange Offer--Procedures for Tendering Old Notes."

                                    Notes tendered pursuant to such offer. The Credit
                                    Facility prohibits the Company from repurchasing any
                                    Notes pursuant to a Change of Control offer prior to the

                                    sufficient available funds to purchase all Notes
                                    tendered pursuant to the Change of Control offer after
                                    first satisfying its obligations under the Credit
                                    Facility or other Senior Debt that may then be
                                    outstanding, if accelerated. The failure by the Company
                                    to purchase all Notes tendered pursuant to the Change of
                                    Control offer would constitute an Event of Default (as
                                    defined). If any Event of Default occurs, the Trustee
                                    (as defined) or holders of at least 25% in principal
                                    amount of the Notes then outstanding may declare the
                                    principal of and the accrued and unpaid interest on such
                                    Notes to be due and payable immediately. However, such
                                    repayment would be subject to certain subordination
                                    provisions in the Indenture (as defined). See "Risk
                                    Factors--Repurchase of Notes Upon a Change of Control
                                    and Certain Other Events" and "Description of
                                    Notes--Ranking and Subordination" and "--Repurchase at

                                    of Default and Remedies."
Ranking...........................  The Notes are general unsecured obligations of the
                                    Company and are subordinated in right of payment to all
                                    existing and future Senior Debt of the Company, which
                                    will include borrowings under the Credit Facility. The
                                    Notes will rank PARI PASSU in right of payment with all
                                    other senior subordinated debt of the Company and any
                                    other indebtedness which does not expressly provide that
                                    it is subordinated in right of payment to the Notes. As
                                    of March 31, 1998, on a pro forma basis after giving
                                    effect to the consummation of the Offering and the
                                    application of the proceeds therefrom and the Worland
                                    Field Acquisition and related financing, the aggregate
                                    principal amount of Senior Debt outstanding would have
                                    been approximately $3.9 million (exclusive of $75.0
                                    million of unused commitments under the Credit Facility)
                                    and there would have been no senior subordinated debt
                                    outstanding (exclusive of the Notes). The Notes will
                                    also be effectively subordinated to all secured
                                    indebtedness of the Company, including indebtedness
                                    under the Credit Facility. See "Capitalization,"
                                    "Description of Notes--Ranking and Subordination" and
                                    "Description of Credit Facility."
Subsidiary Guarantees.............  The Company's payment obligations under the Notes are
                                    jointly, severally and unconditionally guaranteed on a
                                    senior subordinated basis by each Restricted Subsidiary
                                    of the Company and any future Restricted Subsidiary of
                                    the Company. The Subsidiary Guarantees are subordinated
                                    to all Guarantor Senior Debt of the Subsidiary
                                    Guarantors substantially to the same extent and manner
                                    as the Notes are subordinated to Senior Debt. At March
                                    31, 1998, on a pro forma basis, there would have been no
                                    Guarantor Senior Debt outstanding other than the
                                    guarantees of the Credit Facility and the Subsidiary
                                    Guarantees. Each Subsidiary Guarantee will be
                                    effectively subordinated to all secured indebtedness of
                                    the relevant Subsidiary Guarantor, including
                                    indebtedness under the Credit Facility. See "Description
                                    of Notes--Subsidiary Guarantees" and "Description of

- --------------------------
 
(1) In 1997, other income includes $7.5 million resulting from the settlement of
    certain litigation matters.
 
(2) Effective June 1, 1997, the Company elected to be treated as a S Corporation
    for federal income tax purposes. The conversion resulted in the elimination
    of the Company's deferred income tax assets and liabilities existing at May
    31, 1997, and, after being netted against the then existing tax provision,
    resulted in a net income tax benefit to the Company of $8.9 million.
 
(3) EBITDA represents earnings before interest expense, income taxes,
    depreciation, depletion, amortization and exploration expense, excluding
    proceeds from litigation settlements. EBITDA is not a measure of cash flow
    as determined by generally accepted accounting principles ("GAAP"). EBITDA
    should not be considered as an alternative to, or more meaningful than, net
    income or cash flow as determined in accordance with GAAP or as an indicator
    of a company's operating performance or liquidity. Certain items excluded
    from EBITDA are significant components in understanding and assessing a
    company's financial performance, such as a company's cost of capital and tax
    structure, as well as historic costs of depreciable assets, none of which
    are components of EBITDA. The Company's computation of EBITDA may not be
    comparable to other similarly titled measures of other companies. The
    Company believes that EBITDA is a widely followed measure of operating
    performance and may also be used by investors to measure the Company's
    ability to meet future debt service requirements, if any.
 
(4) Capital expenditures include costs related to acquisitions of producing oil
    and gas properties.
 
(5) For purposes of computing the ratio of earnings to fixed charges, earnings
    are computed as income before taxes from continuing operations, plus fixed
    charges. Fixed charges consist of interest expense and amortization of costs
    incurred in the Offering.

                  NOTES TO SUMMARY RESERVE AND OPERATING DATA
 
(1) To give effect to the Worland Field Acquisition as if it had occurred on
    December 31, 1997.
 
(2) Reflects the actual realized prices received by the Company, including the
    results of the Company's hedging activities. See "Management's Discussion
    and Analysis of Financial Condition and Results of Operations."
 
(3) In 1996, the Company changed its fiscal year-end from May 31 to December 31.
    Because reports on a December 31 year-end basis prior to 1996 were not
    available, information as of December 31, 1995 was determined from the
    Company's production, drilling, acquisition and sale data as applied to its
    December 31, 1996 reserve report.
 
(4) Represents the present value of estimated future net cash flows before
    income tax discounted at 10%, using prices in effect at the end of the
    respective periods presented and including the effects of hedging
    activities. In accordance with applicable requirements of the Commission,
    estimates of the Company's proved reserves and future net cash flows are
    made using oil and gas sales prices estimated to be in effect as of the date
    of such reserve estimates and are held constant throughout the life of the
    properties (except to the extent a contract specifically provides for
    escalation). The prices used in calculating PV-10 as of December 31, 1997
    were $18.06 per Bbl of oil and $2.25 per Mcf of natural gas. Average prices
    as of May 31, 1998, on a pro forma basis, were $11.86 per Bbl of oil and
    $1.68 per Mcf of natural gas. These prices, if applied to estimated proved
    reserves of the Company as of December 31, 1997, would result in a PV-10, on
    a pro forma basis, of $170.0 million at such date, as estimated by the
    Company.
 
(5) Reserve life index is calculated by dividing proved reserves by annual
    production (on a Boe basis).
 
(6) Average finding cost is calculated by dividing total costs incurred by
    reserve additions.
 
(7) The three year weighted average finding cost is calculated by dividing the
    sum of the finding costs for the three years ended on December 31 of each of
    the referenced years by the sum of the reserve additions for each of such
    years.
 
(8) To give effect to the Worland Field Acquisition as if it had occurred on
    January 1, 1997.
 
(9) Production volumes are derived from the Company's production records and
    reflect actual quantities of oil and gas produced without regard to the time
    of receipt of proceeds from the sale of such production.
 
(10) Calculated by dividing oil and gas revenues, as reflected on the Financial
    Statements, by production volumes on a Boe basis. Oil and gas revenues
    reflected in the Financial Statements are recognized as production is sold
    and may differ from oil and gas revenues reflected on the Company's
    production records which reflect oil and gas revenues by date of production.
 
(11) Relates to drilling and development activities.
 
(12) Relates to drilling and development activities, net of operating overhead
    income.

                                  RISK FACTORS
 
    IN ADDITION TO THE OTHER INFORMATION SET FORTH ELSEWHERE IN THIS PROSPECTUS,
THE FOLLOWING FACTORS RELATING TO THE COMPANY AND THE OFFERING SHOULD BE
CONSIDERED WHEN EVALUATING AN INVESTMENT IN THE NOTES OFFERED HEREBY.
 
VOLATILITY OF OIL AND GAS PRICES
 
    The Company's revenues, profitability and future rate of growth are
substantially dependent upon prevailing prices for oil and gas and natural gas
liquids, which are dependent upon numerous factors such as weather, economic,
political and regulatory developments and competition from other sources of
energy. The Company is affected more by fluctuations in oil prices than natural
gas prices, because a majority of its production is oil. The volatile nature of
the energy markets and the unpredictability of actions of OPEC members make it
particularly difficult to estimate future prices of oil and gas and natural gas
liquids. Prices of oil and gas and natural gas liquids are subject to wide
fluctuations in response to relatively minor changes in circumstances, and there
can be no assurance that future prolonged decreases in such prices will not
occur. All of these factors are beyond the control of the Company. Any
significant decline in oil and, to a lesser extent, in natural gas prices would
have a material adverse effect on the Company's results of operations and
financial condition. Although the Company may enter into hedging arrangements
from time to time to reduce its exposure to price risks in the sale of its oil
and gas, the Company's hedging arrangements are likely to apply to only a
portion of its production and provide only limited price protection against
fluctuations in the oil and gas markets. See "Management' s Discussion and
Analysis of Financial Condition and Results of Operations" and "Business and
Properties--Oil and Gas Marketing."
 
REPLACEMENT OF RESERVES
 
    The Company's future success depends upon its ability to find, develop or
acquire additional oil and gas reserves that are economically recoverable.
Unless the Company successfully replaces the reserves that it produces (through
successful development, exploration or acquisition), the Company's proved
reserves will decline. There can be no assurance that the Company will continue
to be successful in its effort to increase or replace its proved reserves.
Approximately 37% of the Company's estimated proved reserves at December 31,
1997, on a pro forma basis, was attributable to undeveloped reserves. Recovery
of such reserves will require significant capital expenditures and successful
drilling operations. There can be no certainty regarding the results of
developing these reserves. To the extent the Company is unsuccessful in
replacing or expanding its estimated proved reserves, the Company may be unable
to pay the principal of and interest on the Notes in accordance with their
terms, or otherwise to satisfy certain of its covenants contained in the
Indenture. See "Description of Notes--Certain Covenants."
 
UNCERTAINTY OF ESTIMATES OF OIL AND GAS RESERVES AND FUTURE NET CASH FLOWS
 
    This Prospectus contains estimates of the Company's oil and gas reserves and
the future net cash flows from those reserves which have been prepared by the
Company and certain independent petroleum consultants. Reserve engineering is a
subjective process of estimating the recovery from underground accumulations of
oil and gas that cannot be measured in an exact manner, and the accuracy of any
reserve estimate is a function of the quality of available data and of
engineering and geological interpretation and judgment. There are numerous
uncertainties inherent in estimating quantities and future values of proved oil
and gas reserves, including many factors beyond the control of the Company. Each
of the estimates of proved oil and gas reserves, future net cash flows and
discounted present values relies upon various assumptions, including assumptions
required by the Commission as to constant oil and gas prices, drilling and
operating expenses, capital expenditures, taxes and availability of funds. The
process of estimating oil and gas reserves is complex, requiring significant
decisions and assumptions in the evaluation of available geological,
geophysical, engineering and economic data for each reservoir. As a result, such
estimates are
 
                                       15
<PAGE>
inherently imprecise. Actual future production, oil and gas prices, revenues,
taxes, development expenditures, operating expenses and quantities of
recoverable oil and gas reserves may vary substantially from those estimated in
the report. Any significant variance in these assumptions could materially
affect the estimated quantity and value of reserves set forth in this
Prospectus. In addition, the Company's reserves may be subject to downward or
upward revision, based upon production history, results of future exploration
and development, prevailing oil and gas prices and other factors, many of which
are beyond the Company's control. The PV-10 of the Company's proved oil and gas
reserves does not necessarily represent the current or fair market value of such
proved reserves, and the 10% discount rate required by the Commission may not
reflect current interest rates, the Company's cost of capital or any risks
associated with the development and production of the Company's proved oil and
gas reserves. At December 31, 1997, the estimated future net cash flows and
PV-10 of $545.0 million and $267.0 million, respectively, attributable to the
Company's proved oil and gas reserves, on a pro forma basis, are based on prices
in effect at that date ($14.59 per Bbl of oil and $2.07 per Mcf of natural gas),
which may be materially different than actual future prices. As of May 31, 1998,
the average prices were $11.86 Bbl of oil and $1.68 per Mcf of natural gas, on a
pro forma basis. If such prices were applied to the Company's proved oil and gas
reserves at December 31, 1997, the estimated future net cash flows and PV-10 at
December 31, 1997 would have been approximately $425.0 million and $170.0
million, respectively.
 
PROPERTY ACQUISITION RISKS
 
    The Company's growth strategy includes the acquisition of oil and gas
properties. There can be no assurance, however, that the Company will be able to
identify attractive acquisition opportunities, obtain financing for acquisitions
on satisfactory terms or successfully acquire identified targets. In addition,
no assurance can be given that the Company will be successful in integrating
acquired businesses into its existing operations, and such integration may
result in unforeseen operational difficulties or require a disproportionate
amount of management's attention. Future acquisitions may be financed through
the incurrence of additional indebtedness to the extent permitted under the
Indenture or through the issuance of capital stock. Furthermore, there can be no
assurance that competition for acquisition opportunities in these industries
will not escalate, thereby increasing the cost to the Company of making further
acquisitions or causing the Company to refrain from making additional
acquisitions.
 
    The Company is subject to risks that properties acquired by it (including
those acquired in the Worland Field Acquisition) will not perform as expected
and that the returns from such properties will not support the indebtedness
incurred or the other consideration used to acquire, or the capital expenditures
needed to develop, the properties. The addition of the Worland Field properties
may result in additional impairment of the Company's oil and gas properties to
the extent the Company's net book value of such properties exceeds the projected
discounted future net revenues of the related proved reserves. See "--Writedown
of Carrying Values." In addition, expansion of the Company's operations may
place a significant strain on the Company's management, financial and other
resources. The Company's ability to manage future growth will depend upon its
ability to monitor operations, maintain effective cost and other controls and
significantly expand the Company's internal management, technical and accounting
systems, all of which will result in higher operating expenses. Any failure to
expand these areas and to implement and improve such systems, procedures and
controls in an efficient manner at a pace consistent with the growth of the
Company's business could have a material adverse effect on the Company's
business, financial condition and results of operations. In addition, the
integration of acquired properties with existing operations will entail
considerable expenses in advance of anticipated revenues and may cause
substantial fluctuations in the Company's operating results. There can be no
assurance that the Company will be able to successfully integrate the properties
acquired and to be acquired or any other businesses it may acquire.
 
                                       16
<PAGE>
SUBSTANTIAL CAPITAL REQUIREMENTS
 
    The Company has made, and will continue to make, substantial capital
expenditures in connection with the acquisition, development, exploitation,
exploration and production of its oil and gas properties. Historically, the
Company has funded its capital expenditures through borrowings from banks and
from its principal stockholder, and cash flow from operations. Future cash flows
and the availability of credit are subject to a number of variables, such as the
level of production from existing wells, borrowing base determinations, prices
of oil and gas and the Company's success in locating and producing new oil and
gas reserves. If revenues were to decrease as a result of lower oil and gas
prices, decreased production or otherwise, and the Company had no availability
under its Credit Facility or other sources of borrowings, the Company could have
limited ability to replace its oil and gas reserves or to maintain production at
current levels, resulting in a decrease in production and revenues over time. If
the Company's cash flow from operations and availability under the Credit
Facility are not sufficient to satisfy its capital expenditure requirements,
there can be no assurance that additional debt or equity financing will be
available.
 
EFFECTS OF LEVERAGE
 
    At March 31, 1998, on a pro forma, consolidated basis, the Company and the
Subsidiary Guarantors would have had $153.9 million of indebtedness (including
current maturities of long-term indebtedness) compared to the Company's
stockholders' equity of $80.0 million. See "Use of Proceeds" and
"Capitalization." Although the Company's cash flow from operations has been
sufficient to meet its debt service obligations in the past, there can be no
assurance that the Company's operating results will continue to be sufficient
for the Company to meet its obligations. See "Unaudited Pro Forma Consolidated
Financial Statements," "Selected Consolidated Financial Data," "Capitalization"
and "Management's Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources."
 
    The degree to which the Company is leveraged could have important
consequences to the holders of the Notes, including the following: (i) the
Company's ability to obtain additional financing for acquisitions, capital
expenditures, working capital or general corporate purposes may be impaired in
the future; (ii) a substantial portion of the Company's cash flow from
operations must be dedicated to the payment of principal of and interest on the
Notes and the borrowings under the Credit Facility, thereby reducing funds
available to the Company for its operations and other purposes; (iii) certain of
the Company's borrowings are and will continue to be at variable rates of
interest, which expose the Company to the risk of increased interest rates; (iv)
indebtedness outstanding under the Credit Facility is senior in right of payment
of, is secured by substantially all of the Company's proved reserves and certain
other assets, and will mature prior to the Notes; and (v) the Company may be
substantially more leveraged than certain of its competitors, which may place it
at a relative competitive disadvantage and make it more vulnerable to changing
market conditions and regulations. See "Description of Credit Facility" and
"Description of Notes."
 
    The Company's ability to make scheduled payments or to refinance its
obligations with respect to its indebtedness will depend on its financial and
operating performance, which, in turn, is subject to the volatility of oil and
gas prices, production levels, prevailing economic conditions and to certain
financial, business and other factors beyond its control. If the Company's cash
flow and capital resources are insufficient to fund its debt service
obligations, the Company may be forced to sell assets, obtain additional debt or
equity financing or restructure its debt. Even if additional financing could be
obtained, there can be no assurance that it would be on terms that are favorable
or acceptable to the Company. There can be no assurance that the Company's cash
flow and capital resources will be sufficient to pay its indebtedness in the
future. In the absence of such operating results and resources, the Company
could face substantial liquidity problems and might be required to dispose of
material assets or operations to meet debt service and other obligations, and
there can be no assurance as to the timing of such sales or the adequacy of the
proceeds which the Company could realize therefrom. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations--Liquidity and
Capital Resources" and "Description of Credit Facility."
 
                                       17

RESTRICTIVE COVENANTS
 
    The Credit Facility and the Indenture include certain covenants that, among
other things, restrict: (i) the making of investments, loans and advances and
the paying of dividends and other restricted payments; (ii) the incurrence of
additional indebtedness; (iii) the granting of liens, other than liens created
pursuant to the Credit Facility and certain permitted liens; (iv) mergers,
consolidations and sales of all or a substantial part of the Company's business
or property; (v) the sale of assets; and (vi) the making of capital
expenditures. The Credit Facility requires the Company to maintain certain
financial ratios, including interest coverage and leverage ratios. All of these
restrictive covenants may restrict the Company's ability to expand or pursue its
business strategies. The ability of the Company to comply with these and other
provisions of the Credit Facility may be affected by changes in economic or
business conditions, results of operations or other events beyond the Company's
control. The breach of any of these covenants could result in a default under
the Credit Facility, in which case, depending on the actions taken by the
lenders thereunder or their successors or assignees, such lenders could elect to
declare all amounts borrowed under the Credit Facility, together with accrued
interest, to be due and payable, and the Company could be prohibited from making
payments with respect to the Notes until the default is cured or all Senior Debt
is paid or satisfied in full. If the Company were unable to repay such
borrowings, such lenders could proceed against their collateral. If the
indebtedness under the Credit Facility were to be accelerated, there can be no
assurance that the assets of the Company would be sufficient to repay in full
such indebtedness and the other indebtedness of the Company, including the
Notes. See "Description of Credit Facility" and "Description of Notes--Ranking
and Subordination."
 
OPERATING HAZARDS AND UNINSURED RISKS; PRODUCTION CURTAILMENTS
 
    Oil and gas drilling activities are subject to numerous risks, many of which
are beyond the Company's control, including the risk that no commercially
productive oil and gas reservoirs will be encountered. The cost of drilling,
completing and operating wells is often uncertain, and drilling operations may
be curtailed, delayed or canceled as a result of a variety of factors, including
unexpected drilling conditions, pressure irregularities in formations, equipment
failure or accidents, adverse weather conditions, title problems and shortages
or delays in the delivery of equipment. The Company's future drilling activities
may not be successful and, if unsuccessful, such failure will have an adverse
effect on future results of operations and financial condition.
 
    The Company's properties may be susceptible to hydrocarbon drainage from
production by other operators on adjacent properties. Industry operating risks
include the risk of fire, explosions, blow-outs, pipe failure, abnormally
pressured formations and environmental hazards such as oil spills, gas leaks,
ruptures or discharges of toxic gases, the occurrence of any of which could
result in substantial losses to the Company due to injury or loss of life,
severe damage to or destruction of property, natural resources and equipment,
pollution or other environmental damage, clean-up responsibilities, regulatory
investigation and penalties and suspension of operations. In accordance with
customary industry practice, the Company maintains insurance against the risks
described above. There can be no assurance that any insurance will be adequate
to cover losses or liabilities. The Company cannot predict the continued
availability of insurance, or its availability at premium levels that justify
its purchase.
 
GAS GATHERING AND MARKETING
 
    The Company's gas gathering and marketing operations depend in large part on
the ability of the Company to contract with third party producers to purchase
their gas, to obtain sufficient volumes of committed natural gas reserves, to
replace production from declining wells, to assess and respond to changing
market conditions in negotiating gas purchase and sale agreements and to obtain
satisfactory margins between the purchase price of its natural gas supply and
the sales price for such natural gas. In addition, the Company's operations are
subject to changes in regulations relating to gathering and marketing of oil and
gas. The inability of the Company to attract new sources of third party natural
gas or
 
                                       18
<PAGE>
to promptly respond to changing market conditions or regulations in connection
with its gathering and marketing operations could have a material adverse effect
on the Company's financial condition and results of operations.
 
SUBORDINATION OF NOTES AND GUARANTEES
 
    The Notes are subordinated in right of payment to all existing and future
Senior Debt of the Company, including borrowings under the Credit Facility. In
the event of bankruptcy, liquidation or reorganization of the Company, the
assets of the Company will be available to pay obligations on the Notes only
after all Senior Debt has been paid in full, and there may not be sufficient
assets remaining to pay amounts due on any or all of the Notes outstanding. The
aggregate principal amount of Senior Debt of the Company, as of March 31, 1998,
on a pro forma basis, would have been $3.9 million exclusive of $75.0 million of
unused commitments under the Credit Facility. The Subsidiary Guarantees are
subordinated to Guarantor Senior Debt to the same extent and in the same manner
as the Notes are subordinated to Senior Debt. Additional Senior Debt may be
incurred by the Company or the Subsidiary Guarantors from time to time, subject
to certain restrictions. In addition to being subordinated to all existing and
future Senior Debt of the Company, the Notes will not be secured by any of the
Company's assets, unlike the borrowings under the Credit Facility. See
"Description of Notes--Ranking and Subordination."
 
POSSIBLE UNENFORCEABILITY OF SUBSIDIARY GUARANTEES
 
    The Company derives certain of its operating income from its subsidiaries.
The holders of the Notes will have no direct claim against such subsidiaries
other than a claim created by one or more of the Subsidiary Guarantees, which
may themselves be subject to legal challenge in a bankruptcy or reorganization
case or a lawsuit by or on behalf of creditors of a Subsidiary Guarantor. See
"--Fraudulent Conveyance Considerations." If such a challenge were upheld, such
Subsidiary Guarantees would be invalid and unenforceable. To the extent that any
of such Subsidiary Guarantees are not enforceable, the rights of the holders of
the Notes to participate in any distribution of assets of any Subsidiary
Guarantor upon liquidation, bankruptcy, reorganization or otherwise will, as is
the case with other unsecured creditors of the Company, be subject to prior
claims of creditors of that Subsidiary Guarantor. The Company relies in part
upon distributions from its subsidiaries to generate the funds necessary to meet
its obligations, including the payment of principal of and interest on the
Notes. The Indenture contains covenants that restrict the ability of the
Company's subsidiaries to enter into any agreement limiting distributions and
transfers to the Company, including dividends. However, the ability of the
Company's subsidiaries to make distributions may be restricted by among other
things, applicable state corporate laws and other laws and regulations or by
terms of agreements to which they are or may become a party. In addition, there
can be no assurance that such distributions will be adequate to fund the
interest and principal payments on the Credit Facility and the Notes when due.
See "Description of Notes."
 
REPURCHASE OF NOTES UPON A CHANGE OF CONTROL AND CERTAIN OTHER EVENTS
 
    Upon a Change of Control, holders of the Notes may have the right to require
the Company to repurchase all Notes then outstanding at a purchase price equal
to 101% of the principal amount thereof, plus accrued interest to the date of
repurchase. In the event of certain asset dispositions, the Company will be
required under certain circumstances to use the Excess Cash (as defined herein)
to offer to repurchase the Notes at 100% of the principal amount thereof, plus
accrued interest to the date of repurchase (an "Excess Cash Offer"). See
"Description of Notes--Repurchase at the Option of Holders" and "--Certain
Covenants."
 
    The events that constitute a Change of Control or require an Excess Cash
Offer under the Indenture may also be events of default under the Credit
Facility or other Senior Debt of the Company and the Subsidiary Guarantors, the
terms of which may prohibit the purchase of the Notes by the Company until the
Company's indebtedness under the Credit Facility or other Senior Debt is paid in
full. In addition, such
 
                                       19
<PAGE>
events may permit the lenders under such debt instruments to accelerate the debt
and, if the debt is not paid, to enforce security interests on substantially all
the assets of the Company and the Subsidiary Guarantors, thereby limiting the
Company's ability to raise cash to repurchase the Notes and reducing the
practical benefit of the offer to repurchase provisions to the holders of the
Notes. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations--Liquidity and Capital Resources." There can be no
assurance that the Company will have sufficient funds available at the time of
any Change of Control or Excess Cash Offer to make any debt payment (including
repurchases of Notes) as described above. Any failure by the Company to
repurchase Notes tendered pursuant to a Change of Control Offer (as defined
herein) or an Excess Cash Offer will constitute an Event of Default under the
Indenture. See "Description of Notes--Certain Covenants."
 
RISK OF HEDGING ACTIVITIES
 
    From time to time the Company may use energy swap and forward sale
arrangements to reduce its sensitivity to oil and gas price volatility. If the
Company's reserves are not produced at the rates estimated by the Company due to
inaccuracies in the reserve estimation process, operational difficulties or
regulatory limitations, or otherwise, the Company would be required to satisfy
its obligations under potentially unfavorable terms. If the Company enters into
financial instrument contracts for the purpose of hedging prices and the
estimated production volumes are less than the amount covered by these
contracts, the Company would be required to mark-to-market these contracts and
recognize any and all losses within the determination period. Further, under
financial instrument contracts, the Company may be at risk for basis
differential, which is the difference in the quoted financial price for contract
settlement and the actual physical point of delivery price. The Company will
from time to time attempt to mitigate basis differential risk by entering into
physical basis swap contracts. Substantial variations between the assumptions
and estimates used by the Company in the hedging activities and actual results
experienced could materially adversely affect the Company's anticipated profit
margins and its ability to manage risk associated with fluctuations in oil and
gas prices. Furthermore, the fixed price sales and hedging contracts limit the
benefits the Company will realize if actual prices rise above the contract
prices. The Company had no energy swap or forward sale arrangements in place at
December 31, 1997 or at March 31, 1998.
 
WRITEDOWN OF CARRYING VALUES
 
    The Company periodically reviews the carrying value of its oil and gas
properties in accordance with Statement of Financial Accounting Standards No.
121 "Accounting for the Impairment of Long-Lived Assets and Long-Lived Assets to
be Disposed Of" ("SFAS No. 121"). SFAS No. 121 requires that long-lived assets,
including proved oil and gas properties, and certain identifiable intangibles to
be held and used by the Company be reviewed for impairment whenever events or
changes in circumstances indicate that the carrying amount of an asset may not
be recoverable. In performing the review for recoverability, the Company
estimates the future cash flows expected to result from the use of the asset and
its eventual disposition. If the sum of the expected future cash flows
(undiscounted and without interest charges) is less than the carrying value of
the asset, an impairment loss is recognized in the form of additional
depreciation, depletion and amortization expense. Measurement of an impairment
loss for proved oil and gas properties is calculated on a property-by-property
basis as the excess of the net book value of the property over the projected
discounted future net cash flows of the impaired property, considering expected
reserve additions and price and cost escalations. The Company may be required to
write down the carrying value of its oil and gas properties when oil and gas
prices are depressed or unusually volatile, which would result in a charge to
earnings. Once incurred, a writedown of oil and gas properties is not reversible
at a later date.
 
                                       20
<PAGE>
LAWS AND REGULATIONS; ENVIRONMENTAL RISK
 
    Oil and gas operations are subject to various federal, state and local
governmental regulations which may be changed from time to time in response to
economic or political conditions. From time to time, regulatory agencies have
imposed price controls and limitations on production in order to conserve
supplies of oil and gas. In addition, the production, handling, storage,
transportation and disposal of oil and gas, by-products thereof and other
substances and materials produced or used in connection with oil and gas
operations are subject to regulation under federal, state and local laws and
regulations. See "Business and Properties--Regulation."
 
    The Company is subject to a variety of federal, state and local governmental
regulations related to the storage, use, discharge and disposal of toxic,
volatile or otherwise hazardous materials. These regulations subject the Company
to increased operating costs and potential liability associated with the use and
disposal of hazardous materials. Although these laws and regulations have not
had a material adverse effect on the Company's financial condition or results of
operations, there can be no assurance that the Company will not be required to
make material expenditures in the future. If such laws and regulations become
increasingly stringent in the future, it could lead to additional material costs
for environmental compliance and remediation by the Company. See "Business and
Properties--Regulation."
 
    The Company's twenty years of experience with the use of HPAI technology has
not resulted in any known environmental claims. The Company's saltwater
injection operations will pose certain risks of environmental liability to the
Company. Although the Company will monitor the injection process, any leakage
from the subsurface portions of the wells could cause degradation of fresh
groundwater resources, potentially resulting in suspension of operation of the
wells, fines and penalties from governmental agencies, expenditures for
remediation of the affected resource, and liability to third parties for
property damages and personal injuries. In addition, the sale by the Company of
residual crude oil collected as part of the saltwater injection process could
impose liability on the Company in the event the entity to which the oil was
transferred fails to manage the material in accordance with applicable
environmental health and safety laws.
 
    Any failure by the Company to obtain required permits for, control the use
of, or adequately restrict the discharge of, hazardous substances under present
or future regulations could subject the Company to substantial liability or
could cause its operations to be suspended. Such liability or suspension of
operations could have a material adverse effect on the Company's business,
financial condition and results of operations.
 
COMPETITION
 
    The Company operates in a highly competitive environment. The Company
competes with major and independent oil and gas companies and with individual
producers and developers for the acquisition of desirable oil and gas
properties, as well as for the equipment and labor required to develop and
operate such properties. Many of these competitors have financial and other
resources substantially greater than those of the Company. See "Business and
Properties--Competition."
 
CONTROLLING SHAREHOLDER
 
    At July 31, 1998, Harold Hamm, President and Chief Executive Officer and a
Director of the Company, beneficially owned 44,496 shares of Common Stock
representing, in the aggregate, approximately 91% of the outstanding Common
Stock of the Company. As a result, Harold Hamm is in a position to control the
Company. The Company is provided oilfield services by several affiliated
companies controlled by Harold Hamm. Such transactions will continue in the
future and may result in conflicts of interest between the Company and such
affiliated companies. There can be no assurance that such conflicts will be
resolved in favor of the Company. If Harold Hamm ceases to be an executive
officer of the Company, such would constitute an event of default under the
Credit Facility, unless waived by the
 
                                       21
<PAGE>
requisite percentage of banks. See "Principal Shareholders," "Certain
Relationships and Related Transactions" and "Description of Credit Facility."
 
ABSENCE OF PUBLIC MARKET; RESTRICTIONS ON TRANSFER
 
    The Notes are a new issue of securities for which there has been no public
market and there can be no assurance that such a market for the Notes will
develop or, if such a market develops, as to the liquidity of such market. The
Company does not intend to apply for listing of the Notes on any securities
exchange; however, the Notes have been designated for trading in the PORTAL
market. If the Notes are traded after their initial issuance, they may trade at
a discount from their initial offering price, depending upon prevailing interest
rates, the market for similar securities, the performance of the Company and
certain other factors. Although the Initial Purchaser has informed the Company
that it intends to make a market in the Notes as permitted by applicable laws
and regulations the Initial Purchaser is not obligated to do so and any such
market making activities may be discontinued at any time without notice. See
"Transfer Restrictions," "Exchange and Registration Rights Agreement" and "Plan
of Distribution."
 
FRAUDULENT CONVEYANCE CONSIDERATIONS
 
    The incurrence of indebtedness (such as the Notes) is subject to review
under relevant federal bankruptcy and state fraudulent conveyance statutes in a
bankruptcy or reorganization proceeding or a lawsuit by or on behalf of
creditors of the Company. The Company's obligations under the Notes will be
guaranteed on a subordinated, unsecured basis by existing and future Restricted
Subsidiaries pursuant to the provisions of the Indenture. Under such laws, to
the extent a court were to find that (a) the Notes or a Subsidiary Guarantee was
incurred with the intent to hinder, delay or defraud any present or future
creditor or that the Company or such Subsidiary Guarantor contemplated
insolvency with a design to favor one or more creditors to the exclusion in
whole or in part of other creditors or (b) at the time such person incurred
obligations under the Notes or a Subsidiary Guarantee, it received less than
fair consideration or reasonably equivalent value therefor, and (c) either (i)
was insolvent, (ii) was rendered insolvent by such guarantee or pledge, (iii)
was engaged in a business or transaction for which its remaining unencumbered
assets constituted unreasonably small capital or (iv) intended to incur or
believed that it would incur debts beyond its ability to pay such debts as they
matured, such court could void such obligations and direct the return of any
amounts paid with respect thereto. The measure of insolvency for purposes of the
foregoing will vary depending on the law of the jurisdiction being applied.
Generally, however, an entity would be considered insolvent if the sum of its
debts (including contingent or unliquidated debts) is greater than all of its
property at a fair valuation or if the present fair salable value of its assets
is less than the amount that would be required to pay its probable liability on
its existing debts as they become absolute and mature. There can be no assurance
that, after providing for all prior claims, if any, there would be sufficient
assets to satisfy the claims of the holders of the Notes relating to any voided
portion of a Subsidiary Guarantee. To the extent a Subsidiary Guarantee is
voided as a fraudulent conveyance or held unenforceable for any other reason,
the holders of the Notes would cease to have any claim in respect of such
Subsidiary Guarantor and would be creditors solely of the Company and any other
Subsidiary Guarantors.

                               THE EXCHANGE OFFER
 
PURPOSE AND EFFECT OF THE EXCHANGE OFFER
 
    The Old Notes were sold by the Company on July 24, 1998 to Chase Securities,
Inc. (the "Initial Purchaser") in reliance on Section 4(2) of the Securities
Act. The Placement Agents offered and sold the Old Notes only (i) to "qualified
institutional buyers" (as defined in Rule 144A) in compliance with Rule 144A and
(ii) outside the United States to persons other than U.S. Persons, which term
includes dealers or other professional fiduciaries in the United States acting
on a discretionary basis for foreign beneficial owners (other than an estate or
trust), in reliance upon Regulation S under the Securities Act.
 
    In connection with the sale of the Old Notes, the Company and the Initial
Purchaser entered into a Registration Rights Agreement dated as of July 21, 1998
(the "Registration Rights Agreement"), which requires the Company (i) to cause
the Old Notes to be registered under the Securities Act, or (ii) to file with
the Commission a registration statement under the Securities Act with respect to
an issue of New Notes of the Company identical in all material respects to the
Old Notes and use its best efforts to cause such registration statement to
become effective under the Securities Act and, upon the effectiveness of that
registration statement, to offer to the holders of the Old Notes the opportunity
to exchange their Old Notes for a like principal amount of New Notes, which will
be issued without a restrictive legend and which may be reoffered and resold by
the holder without restrictions or limitations under the Securities Act. A copy
of the Registration Rights Agreement has been filed as an exhibit to the
Registration Statement of which this Prospectus is a part. The Exchange Offer is
being made pursuant to the Registration Rights Agreement to satisfy the
Company's obligations thereunder. The term "holder" with respect to the Exchange
Offer means any person in whose name Old Notes are registered on the Company's
books or any other person who has obtained a properly completed stock power from
the registered holder, or any person whose Old Notes are held of record by The
Depository Trust Company ("DTC") who desires to deliver such Old Notes by
book-entry transfer at DTC.
 
    The Company has not requested, and does not intend to request, an
interpretation by the staff of the Commission with respect to whether the New
Notes issued pursuant to the Exchange Offer in exchange for the Old Notes may be
offered for sale, resold or otherwise transferred by any holder without
compliance with the registration and prospectus delivery provisions of the
Securities Act. Based on interpretations by the staff of the Commission set
forth in no-action letters issued to third parties, the Company believes the New
Notes issued pursuant to the Exchange Offer in exchange for Old Notes may be
offered for resale, resold and otherwise transferred by any holder thereof
(other than broker-dealers, as set forth below, and any such holder that is an
"affiliate" of the Company within the meaning of Rule 405 under the Securities
Act) without compliance with the registration and prospectus delivery provisions
of the Securities Act, provided that such New Notes are acquired in the ordinary
course of such holder's business and that such holder has no arrangement or
understanding with any person to participate in the distribution of such New
Notes. Any holder who tenders in the Exchange Offer with the intention to
participate, or for the purpose of participating, in a distribution of the New
Notes or who is an affiliate of the Company may not rely upon such
interpretations by the staff of the Commission and, in the absence of an
exemption therefrom, must comply with the registration and prospectus delivery
requirements of the Securities Act in connection with any secondary resale
transaction. Failure to comply with such requirements in such instance may
result in such holder incurring liabilities under the Securities Act for which
the holder is not indemnified by the Company. Each broker-dealer (other than an
affiliate of the Company) that receives New Notes for its own account pursuant
to the Exchange Offer must acknowledge that it will deliver a prospectus meeting
the requirements of the Securities Act in connection with any resale of such New
Notes. The Letter of Transmittal states that by so acknowledging and by
delivering a prospectus, a broker-dealer will not be deemed to admit that it is
an "underwriter" within the meaning of the Securities Act. The Company has
agreed that, for a period of 180 days after the Exchange Date, it will make the
Prospectus available to any broker-dealer for use in connection with any such
resale. See "Plan of Distribution."
 
                                       23
<PAGE>
    The Exchange Offer is not being made to, nor will the Company accept
surrenders for exchange from, holders of Old Notes in any jurisdiction in which
this Exchange Offer or the acceptance thereof would not be in compliance with
the securities or blue sky laws of such jurisdiction.
 
    By tendering in the Exchange Offer, each holder of Old Notes will represent
to the Company that, among other things, (i) the New Notes acquired pursuant to
the Exchange Offer are being obtained in the ordinary course of business of the
person receiving such New Notes, whether or not such person is the holder, (ii)
neither the holder of Old Notes nor any such other person has an arrangement or
understanding with any person to participate in the distribution of such New
Notes, (iii) if the holder is not a broker-dealer, or is a broker-dealer but
will not receive New Notes for its own account in exchange for Old Notes,
neither the holder nor any such other person is engaged in or intends to
participate in the distribution of such New Notes, and (iv) neither the holder
nor any such other person is an "affiliate" of the Company within the meaning of
Rule 405 under the Securities Act or, if such holder is an "affiliate," that
such holder will comply with the registration and prospectus delivery
requirements of the Securities Act to the extent applicable.
 
    Following the completion of the Exchange Offer, none of the Old Notes will
be entitled to the contingent increase in interest rate applicable to the Old
Notes. Following the consummation of the Exchange Offer, holders of Old Notes
will not have any further registration rights, and the Old Notes will continue
to be subject to certain restrictions on transfer. See "--Consequences of
Failure to Exchange." Accordingly, the liquidity of the market for the Old Notes
could be adversely affected. See "Risk Factors-- Consequences of the Exchange
Offer on Non-Tendering Holders of the Old Notes."
 
    Participation in the Exchange Offer is voluntary and holders should
carefully consider whether to accept. Holders of the Old Notes are urged to
consult their financial and tax advisors in making their own decisions on
whether to participate in the Exchange Offer.
 
TERMS OF THE EXCHANGE OFFER
 
    GENERAL.  Upon the terms and subject to the conditions set forth in this
Prospectus and in the Letter of Transmittal, the Company will accept any and all
Old Notes validly tendered and not withdrawn prior to 5:00 p.m., New York City
time, on the Expiration Date. The Company will issue $1,000 principal amount of
New Notes in exchange for each $1,000 principal amount of Old Notes accepted in
the Exchange Offer. Holders may tender some or all of their Old Notes pursuant
to the Exchange Offer. However, Old Notes may be tendered only in amounts that
are integral multiples of $1,000 principal amount.
 
    The form and terms of the New Notes will be identical in all material
respects to the form and terms of the Old Notes except that the New Notes will
be registered under the Securities Act and, therefore, certificates representing
New Notes will not bear legends restricting the transfer thereof. The New Notes
will evidence the same debt as the Old Notes, will be entitled to the benefits
of the Indenture and will be treated as a single class thereunder with any Old
Notes that remain outstanding. The Exchange Offer is not conditioned upon any
minimum number of Old Notes being tendered for exchange.
 
    As of               , 1998, $150,000,000 aggregate principal amount of the
Old Notes were outstanding, and there were         registered Holders. This
Prospectus, together with the Letter of Transmittal, is being sent to all
registered holders.
 
    Holders of Old Notes do not have any appraisal or dissenters' rights under
the Oklahoma General Corporation Act or the Indenture in connection with the
Exchange Offer. The Company intends to conduct the Exchange Offer in accordance
with the provisions of the Registration Rights Agreement and the applicable
requirements of the Exchange Act, and the rules and regulations of the
Commission thereunder. Old Notes which are not tendered for exchange in the
Exchange Offer will remain outstanding and interest thereon will continue to
accrue, but such Old Notes will not be entitled to any rights or benefits under
the Registration Rights Agreement.
 
                                       24
<PAGE>
    The Company will be deemed to have accepted validly tendered Old Notes when,
as and if the Company has given oral or written notice thereof to the Exchange
Agent. The Exchange Agent will act as agent for the tendering holders for the
purposes of receiving the New Notes from the Company. If any tendered Old Notes
are not accepted for exchange because of an invalid tender, the occurrence of
certain other events set forth herein or otherwise, certificates for any such
unaccepted Old Notes will be returned, without expense, to the tendering holder
thereof as promptly as practicable after the Expiration Date.
 
    Holders who tender Old Notes in the Exchange Offer will not be required to
pay brokerage commissions or fees or, subject to the instructions in the Letter
of Transmittal, transfer taxes with respect to the exchange of Old Notes
pursuant to the Exchange Offer. The Company will pay all charges and expenses,
other than certain applicable taxes described below, in connection with the
Exchange Offer. See "--Fees and Expenses."
 
    EXPIRATION DATE; EXTENSIONS; AMENDMENTS.  The term "Expiration Date" shall
mean 5:00 p.m., New York City time, on               , 1998, unless the Company,
in its sole discretion, extends the Exchange Offer, in which case the term
"Expiration Date" shall mean the latest date and time to which the Exchange
Offer is extended. Although the Company has no current intention to extend the
Exchange Offer, the Company reserves the right to extend the Exchange Offer at
any time and from time to time by giving oral or written notice to the Exchange
Agent and by timely public announcement communicated, unless otherwise required
by applicable law or regulation, by making a release to the Dow Jones News
Service. During any extension of the Exchange Offer, all Old Notes previously
tendered pursuant to the Exchange Offer and not withdrawn will remain subject to
the Exchange Offer. The date of the exchange of the New Notes for Old Notes will
be as soon as practicable following the Expiration Date.
 
    The Company reserves the right, in its sole discretion, (i) to delay
accepting any Old Notes, to extend the Exchange Offer or to terminate the
Exchange Offer if any of the conditions set forth below under "--Conditions of
the Exchange Offer" shall not have been satisfied, by giving oral or written
notice of such delay, extension or termination to the Exchange Agent, or (ii) to
amend the terms of the Exchange Offer in any manner. Any such delay in
acceptance, extension, termination or amendment will be followed as promptly as
practicable by oral or written notice thereof to the registered holders. If the
Exchange Offer is amended in any manner determined by the Company to constitute
a material change, the Company will promptly disclose such amendment by means of
a prospectus supplement that will be distributed to the registered holders, and
the Company will extend the Exchange Offer for a period of time, depending upon
the significance of the amendment and the manner of disclosure to the registered
holders, if the Exchange Offer would otherwise expire during such period.
 
    In all cases, issuance of the New Notes for Old Notes that are accepted for
exchange pursuant to the Exchange Offer will be made only after timely receipt
by the Exchange Agent of a properly completed and duly executed Letter of
Transmittal and all other required documents; provided, however, that the
Company reserves the absolute right to waive any conditions of the Exchange
Offer or defects or irregularities in the tender of Old Notes. If any tendered
Old Notes are not accepted for any reason set forth in the terms and conditions
of the Exchange Offer or if Old Notes are submitted for a greater principal
amount than the holder desires to exchange, such unaccepted or non-exchanged Old
Notes or substitute Old Notes evidencing the unaccepted portion, as appropriate,
will be returned without expense to the tendering holder, unless otherwise
provided in the Letter of Transmittal, as promptly as practicable after the
expiration or termination of the Exchange Offer.
 
    INTEREST ON THE NEW NOTES.  Holders of Old Notes that are accepted for
exchange will not receive accrued interest thereon at the time of exchange.
However, each New Note will bear interest from the most recent date to which
interest has been paid on the Old Notes or New Notes, or if no interest has been
paid on the Old Notes or the New Notes, from June 12, 1998.
 
                                       25
<PAGE>
    PROCEDURES FOR TENDERING OLD NOTES.  The tender to the Company of Old Notes
by a holder thereof pursuant to one of the procedures set forth below will
constitute an agreement between such holder and the Company in accordance with
the terms and subject to the conditions set forth herein and in the Letter of
Transmittal. A holder of the Old Notes may tender such Old Notes by (i) properly
completing and signing a Letter of Transmittal or a facsimile thereof (all
references in this Prospectus to a Letter of Transmittal shall be deemed to
include a facsimile thereof) and delivering the same, together with any
corresponding certificate or certificates representing the Old Notes being
tendered (if in certificated form) and any required signature guarantees, to the
Exchange Agent at its address set forth in the Letter of Transmittal on or prior
to the Expiration Date (or complying with the procedure for book-entry transfer
described below), or (ii) complying with the guaranteed delivery procedures
described below.
 
    If tendered Old Notes are registered in the name of the signer of the Letter
of Transmittal and the New Notes to be issued in exchange therefor are to be
issued (and any untendered Old Notes are to be reissued) in the name of the
registered holder (which term, for the purposes described herein, shall include
any participant in DTC (also referred to as a book-entry facility) whose name
appears on a security listing as the owner of Old Notes), the signature of such
signer need not be guaranteed. In any other case, the tendered Old Notes must be
endorsed or accompanied by written instruments of transfer in form satisfactory
to the Company and duly executed by the registered holder and the signature on
the endorsement or instrument of transfer must be guaranteed by an eligible
guarantor institution which is a member of one of the following recognized
signature guarantee programs (an "Eligible Institution"): (i) The Securities
Transfer Agents Medallion Program (STAMP), (ii) The New York Stock Exchange
Medallion Signature Program (MSF), or (iii) The Stock Exchange Medallion Program
(SEMP). If the New Notes or Old Notes not exchanged are to be delivered to an
address other than that of the registered holder appearing on the note register
for the Old Notes, the signature in the Letter of Transmittal must be guaranteed
by an Eligible Institution.
 
    THE METHOD OF DELIVERY OF OLD NOTES, THE LETTER OF TRANSMITTAL AND ALL OTHER
REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND RISK OF THE
HOLDER. IF SUCH DELIVERY IS BY MAIL, IT IS RECOMMENDED THAT REGISTERED MAIL,
PROPERLY INSURED, WITH RETURN RECEIPT REQUESTED, BE USED. IN ALL CASES,
SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE DELIVERY TO THE EXCHANGE AGENT
BEFORE THE EXPIRATION DATE. NO LETTER OF TRANSMITTAL OR OLD NOTES SHOULD BE SENT
TO THE COMPANY. HOLDERS MAY REQUEST THEIR RESPECTIVE BROKERS, DEALERS,
COMMERCIAL BANKS, TRUST COMPANIES OR NOMINEES TO EFFECT THE ABOVE TRANSACTIONS
FOR SUCH HOLDERS.
 
    The Company understands that the Exchange Agent has confirmed with DTC that
any financial institution that is a participant in DTC's system may utilize
DTC's Automated Tender Offer Program ("ATOP") to tender Old Notes. The Company
further understands that the Exchange Agent will request, within two business
days after the date the Exchange Offer commences, that DTC establish an account
with respect to the Old Notes for the purpose of facilitating the Exchange
Offer, and any participant may make book-entry delivery of Old Notes by causing
DTC to transfer such Old Notes into the Exchange Agent's account in accordance
with DTC's ATOP procedures for transfer. However, the exchange of the Old Notes
so tendered will only be made after timely confirmation (a "Book-Entry
Confirmation") of such book-entry transfer and timely receipt by the Exchange
Agent of an Agent's Message (as defined in the next sentence), and any other
documents required by the Letter of Transmittal. The term "Agent's Message"
means a message, transmitted by DTC and received by the Exchange Agent and
forming part of Book-Entry Confirmation, which states that DTC has received an
express acknowledgment from a participant tendering Old Notes which are the
subject of such Book-Entry Confirmation and that such participant has received
and agrees to be bound by the terms of the Letter of Transmittal and that the
Company may enforce such agreement against such participant.
 
                                       26
<PAGE>
    A tender will be deemed to have been received as of the date when (i) the
tendering holder's properly completed and duly signed Letter of Transmittal
accompanied by the Old Notes (or a confirmation of book-entry transfer of such
Old Notes into the Exchange Agent's account at DTC), is received by the Exchange
Agent, or (ii) a Notice of Guaranteed Delivery or letter, telegram or facsimile
transmission to similar effect (as provided below) from an Eligible Institution
is received by the Exchange Agent. Issuances of New Notes in exchange for Old
Notes tendered pursuant to a Notice of Guaranteed Delivery or letter, telegram
or facsimile transmission to similar effect (as provided below) by an Eligible
Institution will be made only against submission of a duly signed Letter of
Transmittal (and any other required documents) and deposit of the tendered Old
Notes.
 
    All questions as to the validity, form, eligibility (including time of
receipt) and acceptance for exchange of any tender of Old Notes will be
determined by the Company, whose determination will be final and binding. The
Company reserves the absolute right to reject any or all tenders not in proper
form or the acceptance for exchange of which may, in the opinion of the
Company's counsel, be unlawful. The Company also reserves the absolute right to
waive any of the conditions of the Exchange Offer or any defect or irregularity
in the tender of any Old Notes. None of the Company, the Exchange Agent or any
other person will be under any duty to give notification of any defects or
irregularities in tenders or incur any liability for failure to give any such
notification. Any Old Notes received by the Exchange Agent that are not validly
tendered and as to which the defects or irregularities have not been cured or
waived, or if Old Notes are submitted in principal amount greater than the
principal amount of Old Notes being tendered by such tendering holder, such
unaccepted or non-exchanged Old Notes will be returned by the Exchange Agent to
the tendering holder, unless otherwise provided in the Letter of Transmittal, as
soon as practicable following the Expiration Date.
 
    In addition, the Company reserves the right in its sole discretion (a) to
purchase or make offers for any Old Notes that remain outstanding subsequent to
the Expiration Date, and (b) to the extent permitted by applicable law, to
purchase Old Notes in the open market, in privately negotiated transactions or
otherwise. The terms of any such purchases or offers will differ from the terms
of the Exchange Offer.
 
    GUARANTEED DELIVERY PROCEDURES.  If the holder desires to accept the
Exchange Offer and time will not permit a Letter of Transmittal or Old Notes to
reach the Exchange Agent before the Expiration Date or the procedure for
book-entry transfer cannot be completed on a timely basis, a tender may be
effected if the Exchange Agent has received at its office, on or prior to the
Expiration Date, a letter, telegram or facsimile transmission from an Eligible
Institution setting forth the name and address of the tendering holder, the
name(s) in which the Old Notes are registered and the certificate number(s) of
the Old Notes to be tendered, and stating that the tender is being made thereby
and guaranteeing that, within three New York Stock Exchange trading days after
the date of execution of such letter, telegram or facsimile transmission by the
Eligible Institution, such Old Notes, in proper form for transfer (or a
confirmation of book-entry transfer of such Old Notes into the Exchange Agent's
account at DTC), will be delivered by such Eligible Institution together with a
properly completed and duly executed Letter of Transmittal (and any other
required documents). Unless Old Notes being tendered by the above-described
method are deposited with the Exchange Agent within the time period set forth
above (accompanied or preceded by a properly competed Letter of Transmittal and
any other required documents), the Company may, at its option, reject the
tender. Copies of a Notice of Guaranteed Delivery which may be used by Eligible
Institutions for the purposes described in this paragraph are available from the
Exchange Agent.
 
    TERMS AND CONDITIONS OF THE LETTER OF TRANSMITTAL.  The Letter of
Transmittal contains, among other things, the following terms and conditions,
which are part of the Exchange Offer.
 
    The party tendering Old Notes for exchange (the "Transferor") exchanges,
assigns and transfers the Old Notes to the Company and irrevocably constitutes
and appoints the Exchange Agent as the Transferor's agent and attorney-in-fact
to cause the Old Notes to be assigned, transferred and exchanged. The Transferor
represents and warrants that it has full power and authority to tender,
exchange, assign and
 
                                       27
<PAGE>
transfer the Old Notes and to acquire New Notes issuable upon the exchange of
such tendered Old Notes, and that, when the same are accepted for exchange, the
Company will acquire good and unencumbered title to the tendered Old Notes, free
and clear of all liens, restrictions, charges and encumbrances and not subject
to any adverse claim. The Transferor also warrants that it will, upon request,
execute and deliver any additional documents deemed by the Company to be
necessary or desirable to complete the exchange, assignment and transfer of
tendered Old Notes or to transfer ownership of such Old Notes on the account
books maintained by DTC. All authority conferred by the Transferor will survive
the death, bankruptcy or incapacity of the Transferor and every obligation of
the Transferor shall be binding upon the heirs, personal representatives,
executors, administrators, successors, assigns, trustees in bankruptcy and other
legal representatives of such Transferor.
 
    By executing a Letter of Transmittal, each holder will make to the Company
the representations set forth above under the heading "--Purpose and Effect of
the Exchange Offer."
 
    WITHDRAWAL OF TENDERS OF OLD NOTES.  Except as otherwise provided herein,
tenders of Old Notes may be withdrawn at any time prior to 5:00 p.m., New York
City time, on the Expiration Date.
 
    To withdraw a tender of Old Notes in the Exchange Offer, a written or
facsimile transmission notice of withdrawal must be received by the Exchange
Agent at its address set forth herein prior to 5:00 p.m., New York City time, on
the Expiration Date. Any such notice of withdrawal must (i) specify the name of
the person having deposited the Old Notes to be withdrawn (the "Depositor"),
(ii) identify the Old Notes to be withdrawn (including the certificate number or
numbers and principal amount of such Old Notes), (iii) contain a statement that
such holder is withdrawing its election to have such Old Notes exchanged, (iv)
be signed by the holder in the same manner as the original signature on the
Letter of Transmittal by which such Old Notes were tendered (including any
required signature guarantees) or be accompanied by documents of transfer
sufficient to have the Trustee with respect to the Old Notes register the
transfer of such Old Notes in the name of the person withdrawing the tender, and
(v) specify the name in which any such Old Notes are to be registered, if
different from that of the Depositor. If Old Notes have been tendered pursuant
to the procedure for book-entry transfer, any notice of withdrawal must specify
the name and number of the account at the book-entry transfer facility. All
questions as to the validity, form and eligibility (including time of receipt)
of such notices will be determined by the Company, whose determination shall be
final and binding on all parties. Any Old Notes so withdrawn will be deemed not
to have been validly tendered for purposes of the Exchange Offer and no New
Notes will be issued with respect thereto unless the Old Notes so withdrawn are
validly retendered. Any Old Notes which have been tendered but which are not
accepted for exchange will be returned to the holder thereof without cost to
such holder as soon as practicable after withdrawal, rejection of tender or
termination of the Exchange Offer. Properly withdrawn Old Notes may be
retendered by following one of the procedures described above under
"--Procedures for Tendering Old Notes" at any time prior to the Expiration Date.
 
CONDITIONS OF THE EXCHANGE OFFER
 
    Notwithstanding any other term of the Exchange Offer, or any extension of
the Exchange Offer, the Company shall not be required to accept for exchange, or
exchange New Notes for, any Old Notes, and may terminate the Exchange Offer as
provided herein before the acceptance of such Old Notes, if:
 
        (a) any statute, rule or regulation shall have been enacted, or any
    action shall have been taken by any court or governmental authority which,
    in the reasonable judgment of the Company, would prohibit, restrict or
    otherwise render illegal consummation of the Exchange Offer; or
 
        (b) any change, or any development involving a prospective change, in
    the business or financial affairs of the Company or any of its subsidiaries
    has occurred which, in the sole judgment of the Company, might materially
    impair the ability of the Company to proceed with the Exchange Offer or
    materially impair the contemplated benefits of the Exchange Offer to the
    Company; or
 
                                       28
<PAGE>
        (c) there shall occur a change in the current interpretations by the
    staff of the Commission which, in the Company's reasonable judgment, might
    materially impair the Company's ability to proceed with the Exchange Offer.
 
    If the Company determines in its sole discretion that any of the above
conditions are not satisfied, the Company may (i) refuse to accept any Old Notes
and return all tendered Old Notes to the tendering holders, (ii) extend the
Exchange Offer and retain all Old Notes tendered prior to the Expiration Date,
subject, however, to the right of holders to withdraw such Old Notes (see
"--Terms of the Exchange Offer--Withdrawal of Tenders of Old Notes"), or (iii)
waive such unsatisfied conditions with respect to the Exchange Offer and accept
all validly tendered Old Notes which have not been withdrawn. If such waiver
constitutes a material change to the Exchange Offer, the Company will promptly
disclose such waiver by means of a prospectus supplement that will be
distributed to the registered holders, and the Company will extend the Exchange
Offer for a period of time, depending upon the significance of the waiver and
the manner of disclosure to the registered holders, if the Exchange Offer would
otherwise expire during such period.

FEES AND EXPENSES
 
    The expenses of soliciting tenders will be borne by the Company. The
principal solicitation is being made by mail; however, additional solicitation
may be made by telecopy, telephone or in person by officers and regular
employees of the Company and its affiliates. No additional compensation will be
paid to any such officers and employees who engage in soliciting tenders.
 
    The Company has not retained any dealer-manager or other soliciting agent in
connection with the Exchange Offer and will not make any payments to brokers,
dealers or others soliciting acceptance of the Exchange Offer. The Company,
however, will pay the Exchange Agent reasonable and customary fees for its
services and will reimburse it for its reasonable out-of-pocket expenses in
connection therewith. The Company may also pay brokerage houses and other
custodians, nominees and fiduciaries the reasonable out-of-pocket expenses
incurred by them in forwarding copies of this Prospectus, the Letter of
Transmittal
 
                                       29
<PAGE>
and related documents to the beneficial owners of the Old Notes and in handling
or forwarding tenders for exchange.
 
    The expenses to be incurred in connection with the Exchange Offer will be
paid by the Company. Such expenses include fees and expenses of the Exchange
Agent and transfer agent and registrar, accounting and legal fees and printing
costs, among others.
 
    The Company will pay all transfer taxes, if any, applicable to the exchange
of the Old Notes pursuant to the Exchange Offer. If, however, New Notes, or Old
Notes for principal amounts not tendered or accepted for exchange, are to be
delivered to, or are to be issued in the name of, any person other than the
registered holder of the Old Notes tendered or if a transfer tax is imposed for
any reason other than the exchange of the Old Notes pursuant to the Exchange
Offer, then the amount of any such transfer taxes (whether imposed on the
registered holder or any other persons) will be payable by the tendering holder.
If satisfactory evidence of payment of such taxes or exemption therefrom is not
submitted with the Letter of Transmittal, the amount of such transfer taxes will
be billed directly to such tendering holder.
 
CONSEQUENCES OF FAILURE TO EXCHANGE
 
    The Old Notes that are not exchanged for New Notes pursuant to the Exchange
Offer will remain restricted securities within the meaning of Rule 144 of the
Securities Act. Accordingly, such Old Notes may be resold only (i) to the
Company or any subsidiary thereof, (ii) to a qualified institutional buyer in
compliance with Rule 144A, (iii) to an institutional accredited investor that,
prior to such transfer, furnishes to the Trustee a signed letter containing
certain representations and agreements relating to the restrictions on transfer
of the Old Notes (the form of which letter can be obtained from the Trustee)
and, if such transfer is in respect of an aggregate principal amount of Old
Notes at the time of transfer of less than $100,000, an opinion of counsel
acceptable to the Company that such transfer is in compliance with the
Securities Act, (iv) outside the United States in compliance with Rule 904 under
the Securities Act, (v) pursuant to the exemption from registration provided by
Rule 144 under the Securities Act (if available), or (vi) pursuant to an
effective registration statement under the Securities Act. The liquidity of the
Old Notes could be adversely affected by the Exchange Offer. Following the
consummation of the Exchange Offer, holders of the Senior Preferred Stock will
have no further registration rights under the Registration Rights Agreement and
will not be entitled to the contingent increase in the dividend rate applicable
to the Old Notes.

(a) To record the revenues and direct operating expenses attributable to the
    Company's net interest in oil and gas properties acquired in the Worland
    Field Acquisition for the periods indicated.
 
(b) To record estimated pro forma depreciation, depletion and amortization
    related to the Company's net interest in the Worland Field properties as if
    the Worland Field Acquisition had occurred on January 1, 1997. The estimated
    pro forma depreciation, depletion and amortization was at an average rate of
    $1.53 per Boe based on an allocation of the purchase price to the individual
    properties acquired and the actual production during the year ended December
    31, 1997.
 
(c) To record the pro forma amortization of estimated costs of the Offering,
    assuming the Offering was completed on January 1, 1997.
 
(d) To record the estimated pro forma interest income resulting from an
    investment at a 5% interest rate of the net proceeds of the Offering
    remaining after payment of the Credit Facility, assuming the Offering was
    consummated on January 1, 1997.
 
(e) To record the pro forma effect of interest expense related to the Notes
    assuming (i) the Offering occurred on January 1, 1997 and (ii) the net
    proceeds from the Offering are used to reduce debt outstanding under the
    Credit Facility which was incurred to finance the Worland Field Acquisition,
    and taking into consideration the proceeds from the sale of a 50% interest
    in the Worland Field properties to the Company's principal shareholder as if
    the sale had occurred on January 1, 1997. In May 1998, the Company entered
    into a forward interest rate swap contract to hedge its exposure to changes
    in prevailing interest rates. Due to changes in treasury note rates, the
    Company paid $3.9 million to settle the forward interest rate swap contract.
    This payment will result in an increase of approximately 0.5% to the
    Company's effective interest rate or an increase in interest expense of
    approximately $0.4 million per year over the next 10 years. As this
    transaction was not directly attributable to the Offering of the Notes, no
    pro forma adjustments have been made to reflect its impact.

                 NOTES TO SELECTED CONSOLIDATED FINANCIAL DATA
 
(1) In 1993, other income includes $4.0 million resulting from the settlement of
    certain litigation matters.
 
(2) In 1997, other income includes $7.5 million resulting from the settlement of
    certain litigation matters.
 
(3) Effective June 1, 1997, the Company elected to be treated as a S Corporation
    for federal income tax purposes. The conversion resulted in the elimination
    of the Company's deferred income tax assets and liabilities existing at May
    31, 1997 and, after being netted against the then existing tax provision,
    resulted in a net income tax benefit to the Company of $8.9 million.
 
(4) EBITDA represents earnings before interest expense, income taxes,
    depreciation, depletion, amortization and exploration expense, excluding
    proceeds from litigation settlements. EBITDA is not a measure of cash flow
    as determined in accordance with GAAP. EBITDA should not be considered as an
    alternative to, or more meaningful than, net income or cash flow as
    determined in accordance with GAAP or as an indicator of a company's
    operating performance or liquidity. Certain items excluded from EBITDA are
    significant components in understanding and assessing a company's financial
    performance, such as a company's cost of capital and tax structure, as well
    as historic costs of depreciable assets, none of which are components of
    EBITDA. The Company's computation of EBITDA may not be comparable to other
    similarly titled measures of other companies. The Company believes that
    EBITDA is a widely followed measure of operating performance and may also be
    used by investors to measure the Company's ability to meet future debt
    service requirements, if any.
 
(5) Capital expenditures include costs related to acquisitions of producing oil
    and gas properties.
 
(6) For purposes of computing the ratio of earnings to fixed charges, earnings
    are computed as income before taxes from continuing operations, plus fixed
    charges. Fixed charges consist of interest expense and amortization of costs
    incurred in the Offering.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
    The following discussion should be read in conjunction with the Company's
consolidated financial statements and notes thereto and the Selected
Consolidated Financial Data included elsewhere herein.
 
OVERVIEW
 
    The Company's revenue, profitability and cash flow are substantially
dependent upon prevailing prices for oil and gas and the volumes of oil and gas
it produces. Although the Company produced more oil and gas in the first quarter
of 1998 than in the first quarter of 1997, it experienced a significant decline
in revenues, net income and EBITDA in the first quarter of 1998 compared to the
first quarter of 1997 because of lower prevailing oil and gas prices. These
lower prices have continued to adversely affect the Company's revenues and
results of operation since March 31, 1998. Given the volatile nature of oil and
gas prices, it is difficult to predict whether such effects will continue during
the remainder of 1998. Average prices as of May 31, 1998, on a pro forma basis,
were $11.86 per Bbl of oil and $1.68 per Mcf of natural gas compared to $18.06
per Bbl of oil and $2.25 per Mcf of natural gas as of December 31, 1997. If the
May 31, 1998 pro forma prices were applied to the Company's estimated proved
reserves as of December 31, 1997, the Company's pro forma PV-10 would have been
approximately $170.0 million compared to a pro forma PV-10 of $267.0 million
using December 31, 1997 prices. In addition, the Company's proved reserves and
oil and gas production will decline as oil and gas are produced unless the
Company is successful in acquiring producing properties or conducting successful
exploration and development drilling activities.
 
    The Company uses the successful efforts method of accounting for its
investment in oil and gas properties. Under the successful efforts method of
accounting, costs to acquire mineral interests in oil and gas properties, to
drill and provide equipment for exploratory wells that find proved reserves and
to drill and equip development wells are capitalized. These costs are amortized
to operations on a unit-of-production method based on petroleum engineer
estimates. Geological and geophysical costs, lease rentals and costs associated
with unsuccessful exploratory wells are expensed as incurred. Maintenance and
repairs are expensed as incurred, except that the cost of replacements or
renewals that expand capacity or improve production are capitalized. Significant
downward revisions of quantity estimates or declines in oil and gas prices that
are not offset by other factors could result in a writedown for impairment of
the carrying value of oil and gas properties. Once incurred, a writedown of oil
and gas properties is not reversible at a later date, even if oil or gas prices
increase.
 
    The Company is a S Corporation for federal income tax purposes. The Company
currently anticipates it will pay quarterly dividends in amounts sufficient to
enable the Company's shareholders to pay their income tax obligations with
respect to the Company's taxable earnings.

    EBITDA. The Company's computation of EBITDA may not be comparable to other
    similarly titled measures of other companies. The Company believes that
    EBITDA is a widely followed measure of operating performance and may also be
    used by investors to measure the Company's ability to meet future debt
    service requirements, if any.
 
(2) Production volumes of oil and condensate, and natural gas, are derived from
    the Company's production records and reflect actual quantities produced
    without regard to the time of receipt of proceeds from the sale of such
    production. Production volumes of oil equivalents (on a Boe basis) are
    determined by dividing the total Mcfs of natural gas produced by six and by
    adding the resultant sum to barrels of oil and condensate produced.
 
(3) Average prices of oil and condensate, and of natural gas, are derived from
    the Company's production records which are maintained on an "as produced"
    basis, which give effect to gas balancing and oil produced and in the tanks,
    and, accordingly, may differ from oil and gas revenues for the same periods
    as reflected in the Financial Statements. Average prices of oil equivalents
    were calculated by dividing oil and gas revenues, as reflected in the
    Financial Statements, by production volumes on a per Boe basis. Average sale
    prices per Boe realized by the Company, according to its production records
    which are maintained on an "as produced" basis, for the years ended December
    31, 1995, 1996 and 1997, were $13.19, $18.59 and $17.53, respectively.
 
THREE MONTHS ENDED MARCH 31, 1998 COMPARED TO THREE MONTHS ENDED MARCH 31, 1997
 
    OIL AND GAS SALES revenue in the first quarter of 1998 was $16.1 million, a
decrease of $4.7 million, or 23%, from $20.8 million in the same period in 1997.

received average prices of $13.77 per Bbl and $1.77 per Mcf, compared to $21.15
per Bbl and $2.76 per Mcf, respectively, for the same period in 1997.
 
    GATHERING, MARKETING AND PROCESSING revenue in the first quarter of 1998 was
$6.6 million, a decrease of $4.1 million, or 38%, from $10.7 million in the same
period in 1997, which was attributable primarily to lower prices for natural gas
and natural gas liquids.
 
    OIL AND GAS SERVICE OPERATIONS revenue in the first quarter of 1998 was $1.5
million, a decrease of $0.5 million, or 27%, compared to $2.0 million in the
same period in 1997, which was attributable to declining oil prices on reclaimed
oil sales.
 
    PRODUCTION EXPENSES AND TAXES in the first quarter of 1998 were $4.8
million, a decrease of $0.1 million, or 2%, compared to $4.9 million in the same
period in 1997, which was attributable to increased production efficiencies and
lower gross production taxes per Boe due to price declines.
 
    EXPLORATION EXPENSES in the first quarter of 1998 were $1.5 million, an
increase of $0.5 million, or 59%, compared to $1.0 million in the same period in
1997, resulting primarily from a $0.2 million increase in expired lease expense
and a $0.2 million increase in dry hole expense.
 
    GATHERING, MARKETING AND PROCESSING EXPENSE in the first quarter of 1998 was
$5.8 million, a $3.0 million, or 34% decrease compared to $8.8 million in the
same period in 1997. The decrease was attributable primarily to lower prices for
natural gas and natural gas liquids.
 
    OIL AND GAS SERVICE OPERATIONS EXPENSE in the first quarter of 1998 was $0.9
million, a $0.1 million, or 14% decrease from $1.0 million in the same period in
1997, which was attributable to reduced costs of reclaimed oil.
 
    DEPRECIATION, DEPLETION AND AMORTIZATION ("DD&A") EXPENSE in the first
quarter of 1998 was $5.4 million, a $3.4 million, or 39% decrease compared to
$8.8 million in 1997. DD&A expense related to oil and gas operations in the
first quarter of 1998 was $4.6 million, a $3.6 million, or 44% decrease compared
to $8.2 million in the same period in 1997. The decreases were attributable
primarily to lower production levels in the 1998 period. The unit rate of DD&A
expense per Boe in the first quarter of 1998 was $3.73, compared with $7.88 in
the 1997 period.
 
    GENERAL AND ADMINISTRATIVE ("G&A") EXPENSE in the first quarter of 1998 was
$2.2 million minus overhead reimbursement of $0.5 million for a net G&A expense
of $1.7 million, or an increase of $0.8 million, or 43%, compared to G&A expense
of $1.8 million in the first quarter of 1997 minus overhead reimbursement of
$0.9 million for a net G&A expense of $0.9 million. The increase was primarily
due to an employment and benefits increase of $0.2 million and a reduction of
overhead reimbursement of $0.5 million.
 
    INTEREST EXPENSE in the first quarter of 1998 was $2.0 million, an increase
of $0.9 million, or 80%, compared to $1.1 million in the 1997 period
attributable primarily to higher levels of indebtedness outstanding during 1998.
 
    INTEREST AND OTHER INCOME in the first quarter of 1998 was $0.3 million, a
decrease of $0.3 million, or 44%, from $0.6 million realized in the same period
in 1997. The decrease was primarily attributable to fewer assets being sold in
the 1998 period compared to the 1997 period.
 
    INCOME BEFORE INCOME TAXES in the first quarter of 1998 was $1.7 million, a
decrease of $2.4 million, or 58%, from $4.1 million in the 1997 period,
attributable primarily to lower revenues from oil and gas sales, gathering,
marketing and processing, oil and gas service operations and other income
partially offset by reduced production expenses and taxes, gathering, marketing
and processing expenses, DD&A expense, partially offset by an increase in
general and administrative expense.
 
                                       40
<PAGE>
    NET INCOME in the first quarter of 1998 was $1.7 million, a decrease of $4.9
million, or 74%, compared to $6.6 million in the 1997 period, primarily
attributable to lower income before income taxes caused by lower oil prices.
 
YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996
 
    OIL AND GAS SALES revenue in 1997 was $78.6 million, an increase of $3.6

    PRODUCTION EXPENSES AND TAXES in 1997 were $20.7 million, an increase of
$1.4 million, or 7%, compared to $19.3 million in 1996, which was attributable
to a 13% increase in production volume offset by a 5% decrease in production
costs per Boe.
 
    EXPLORATION EXPENSES were $6.8 million in 1997, an increase of $2.3 million,
or 51%, compared to $4.5 million in 1996, resulting primarily from a $0.5
million increase in expired lease expense and a $1.0 million increase in 3-D
seismic expenditures.
 
    GATHERING, MARKETING AND PROCESSING EXPENSE in 1997 was $22.7 million, a
$0.9 million, or 4% increase, compared to $21.8 million, which in 1996 was
attributable to reduced margins on natural gas and natural gas liquids.
 
    OIL AND GAS SERVICE OPERATIONS EXPENSE in 1997 was $3.7 million, a $0.3
million, or 9%, decrease from $4.0 million in 1996, attributable to a reduction
in saltwater disposal activity and warehouse activity.
 
    DD&A EXPENSE in 1997 was $33.4 million, a $10.5 million, or 46% increase
compared to $22.9 million in 1996. DD&A expense related to oil and gas
operations in 1997 was $30.2 million, an $8.6 million, or 40% increase, compared
to $21.6 million in 1996, attributable primarily to higher production levels in
1997. The unit rate of DD&A expense per Boe in 1997 was $6.74, compared with
$5.44 in 1996. The 1997 DD&A rate included $5.0 million of additional impairment
for writedown of certain long-lived assets in accordance with the provisions of
SFAS No. 121, or $1.12 per Boe.
 
    G&A EXPENSE for 1997 was $9.0 million minus overhead reimbursement of $2.4
million for a net G&A expense of $6.6 million, which was equal to net G&A
expense of 6.6 million in 1996.
 
    INTEREST EXPENSE in 1997 was $4.8 million, an increase of $0.2 million, or
6%, compared to $4.6 million in 1996, attributable primarily to higher levels of
indebtedness outstanding during 1997.
 
    INTEREST AND OTHER INCOME in 1997 was $8.3 million, a $7.8 million, or
1,560%, increase over $0.5 million realized in 1996. The substantial increase in
1997 was primarily attributable to non-recurring income of approximately $7.5
million resulting from the settlement of certain litigation matters.
 
    INCOME BEFORE INCOME TAXES in 1997 was $17.3 million, a decrease of $4.3
million, or 20%, from $21.6 million in 1996, attributable primarily to increased
production expenses and taxes, exploration expenses, gathering, marketing and
processing expenses and DD&A expense, partially offset by an increase in total
revenues of approximately $10.5 million, which included approximately $7.5
million related to the settlement of certain litigation matters.
 
                                       41
<PAGE>
    NET INCOME in 1997 was $26.2 million, an increase of $12.9 million, or 97%,
compared to $13.3 million in 1996, primarily attributable to an $8.9 million tax
benefit realized in 1997, compared to a $8.2 million tax expense in 1996, and
the recognition of approximately $7.5 million related to the settlement of
certain litigation matters.
 
YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995
 
    OIL AND GAS SALES revenue in 1996 was $75.0 million, an increase of $44.4
million, or 145%, over $30.6 million in 1995. In 1996, the Company sold an
aggregate of 2,888 MBbls, a 141% increase over 1995 oil sales of 1,199 MBbls.
The Company's natural gas sales in 1996 aggregated to 6,527 MMcf, an 11%

received average prices of $20.78 per Bbl and $2.13 per Mcf, compared to $17.11
per Bbl and $1.40 per Mcf, respectively, in 1995.
 
    GATHERING, MARKETING AND PROCESSING revenue in 1996 was $25.8 million, an
increase of $5.2 million, or 25%, from $20.6 million in 1995, attributable to
increased throughput on the Company's natural gas gathering systems.
 
    OIL AND GAS SERVICE OPERATIONS revenue in 1996 was $6.5 million, an increase
of $0.4 million, or 6%, compared to $6.1 million in 1995, attributable to an
increase in warehouse pipe sales.
 
    PRODUCTION EXPENSES AND TAXES in 1996 were $19.3 million, an increase of
$11.7 million, or 154%, compared to $7.6 million in 1995, attributable to
increased production volumes.
 
    EXPLORATION EXPENSES in 1996 were $4.5 million, a decrease of $1.6 million,
or 27%, compared to $6.2 million in 1995, resulting primarily from a reduction
of dry hole expenses of $1.6 million.
 
    GATHERING, MARKETING AND PROCESSING EXPENSE in 1996 was $21.8 million, an
$8.6 million, or 65% increase, compared to $13.2 million in 1995, was

    INCOME BEFORE INCOME TAXES in 1996 was $21.6 million, an increase of $15.5
million, or 252%, from $6.1 million in 1995, attributable primarily to increased
oil and gas sales and gathering, marketing and processing revenues, partially
offset by increases in production expenses and taxes, gathering, marketing and
processing expenses and DD&A expense.
 
                                       42
<PAGE>
    NET INCOME in 1996 was $13.3 million, an increase of $9.4 million, or 244%,
compared to $3.9 million in 1995, primarily attributable to increased income
before income taxes partially offset by a larger income tax expense.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    During 1997, and the three months ended March 31, 1998, the Company utilized
its beginning cash balance, cash flow from operations and financing provided by
a bank and by the Company's principal shareholder to fund its exploration and
development expenditures, as well as the construction of a natural gas
processing plant and pipeline infrastructure in the Williston Basin.
 
    CASH FLOW FROM OPERATIONS.  Net cash provided by operating activities was
$51.5 million for 1997, a 23% and 171% increase from the $41.7 million and $19.0
million in 1996 and 1995, respectively. Net cash provided by operating
activities was $4.0 million for the three months ended March 31, 1998, a 78%
decrease from the $17.9 million for the three months ended March 31, 1997. Cash
and short-term cash investments decreased to $1.3 million at December 31, 1997,
from $3.3 million at year-end 1996, and decreased to $1.3 million at March 31,
1998, from $1.4 million at March 31, 1997.
 
    RESERVES ADDED AND FINDING COST.  During 1997 and the three months ended
March 31, 1998, the Company spent $59.5 million and $12.9 million, respectively,
on acquisitions, exploration, exploitation and development of oil and gas
properties. Total estimated proved reserves of natural gas decreased from 50.5
Bcf at year-end 1996 to 49.4 Bcf at year-end 1997, and estimated total proved
oil reserves increased from 19.5 MMBbls at year-end 1996 to 24.7 MMBbls at
year-end 1997.
 
    FINANCING.  Total long-term debt at December 31, 1997 and March 31, 1998 was
$79.6 million and $100.7 million, respectively, compared to $54.8 million and
$53.7 million (including current portion) at December 31, 1996 and March 31,
1997, respectively.
 
    CREDIT FACILITY.  Total long-term debt outstanding at December 31, 1997 and
March 31, 1998, included $53.7 million and $72.4 million, respectively, of
revolving credit debt under the Credit Facility. The Credit Facility matures May
14, 2001. The Credit Facility provides for interest based on the prime rate of
Bank One Oklahoma, N.A., or the London Interbank Offered Rate rounded to the
nearest 0.01%, adjusted for maximum cost of reserves rate, plus 100 to 175 basis
points. The effective rate of interest under the Credit Facility at December 31,
1997 was 7.7% and at March 31, 1998 was 7.8%. Upon completion of the Offering
and the application of the proceeds therefrom, the Credit Facility is expected
to be amended and restated as a $75.0 million credit facility with a $75.0
million borrowing base. All other terms thereof are expected to remain
substantially unchanged.
 
    CAPITAL EXPENDITURES.  The Company expects higher production volumes in 1998
compared to 1997. The expected increase in volume is primarily due to the
production associated with the Worland Field properties, as well as certain new
oil and gas properties expected to commence production during the year. Revenue
in 1998, however, has been and continues to be adversely impacted by lower
prevailing oil and gas prices, which are expected to remain volatile. The
Company's 1998 capital expenditures budget is $45.4 million, exclusive of
acquisitions. During the three months ended March 31, 1998, the Company incurred
$16.0 million of capital expenditures, exclusive of acquisitions. The Company
expects to fund the 1998 capital budget through cash flow from operations and
its Credit Facility.
 
    OTHER.  The Company follows the "sales method" of accounting for its gas
revenue, whereby the Company recognizes sales revenue on all gas sold,
regardless of whether the sales are proportionate to the Company's ownership in
the property. A liability is recognized only to the extent that the Company has
a net imbalance in excess of its share of the reserves in the underlying
properties. The Company's historical aggregate imbalance positions have been
immaterial. The Company believes that any future periodic settlements of gas
imbalances will have little impact on its liquidity.
 
                                       43
<PAGE>
    The Company has sold a number of non-strategic oil and gas properties and
other properties over the past three years, recognizing a pretax loss of
approximately $411,000 in 1995, and pretax gains of approximately $233,000 and
$674,000 in 1996 and 1997, respectively. Total amounts of oil and gas reserves
associated with these dispositions during the last three years were 294 MBbls of
oil and 2,298 MMcf of natural gas.
 
    YEAR 2000.  Year 2000 issues result from the inability of computer programs
or computerized equipment to accurately calculate, store or use a date
subsequent to December 31, 1999. The erroneous date can be interpreted in a
number of different ways; typically the year 2000 is represented as the year
1900. This could result in a system failure or miscalculations causing
disruptions of operations, including, among other things, a temporary inability
to process transactions, send invoices, or engage in similar normal business
activities.
 
    The Company has been advised by its computer consultant that the Company's
mainframe computer and operating systems are year 2000 compliant. The Company's
application software will be modified to be year 2000 compliant during 1998 and
1999 at a cost estimated to be less than $100,000.
 
    Assessment of other less critical software systems and various types of
equipment is continuing and should be completed by November 1998. The Company
believes that the potential impact, if any, of these systems not being year 2000
compliant will at most require employees to manually complete otherwise
automated tasks or calculations. There can be no guarantee that the systems of
other companies on which the Company's systems rely will be timely converted, or
that a failure to convert by another company, or a conversion that is
incompatible with the Company's systems would not have a material adverse effect
on the Company.
 
    HEDGING.  From time to time, the Company may use energy swap and forward
sale arrangements to reduce its sensitivity to oil and gas price volatility.
However, the Company had no energy swap or forward sale arrangement in place at
December 31, 1997 or at March 31, 1998.
 
    The Company has only limited involvement with derivative financial
instruments, as defined in SFAS No. 119 "Disclosure About Derivative Financial
Instruments and Fair Value of Financial Instruments" and does not use them for
trading purposes. The Company's objective is to hedge a portion of its exposure
to price volatility from producing oil and natural gas. These arrangements
expose the Company to the credit risk of its counterparties and to basis risk.

                            BUSINESS AND PROPERTIES
 
GENERAL
 
    Continental is engaged in the development, exploitation, exploration and
acquisition of oil and gas reserves, primarily in the Rocky Mountains and the
Mid-Continent and, to a lesser extent, in the Gulf Coast region of Texas and
Louisiana. In addition to its exploration, development and production
activities, the Company owns and operates 1,000 miles of natural gas pipelines,
five gas gathering systems and three gas processing plants in its operating
areas. The Company also engages in natural gas marketing, gas pipeline
construction and saltwater disposal. Capitalizing on its growth through the
drill-bit and its acquisition strategy, on a pro forma basis the Company has
increased its estimated proved reserves from 12.7 MMBoe in 1993 to 64.9 MMBoe in
1997, and increased its annual production from 2.0 MMBoe in 1993 to 5.2 MMBoe in
1997. At December 31, 1997, on a pro forma basis, approximately 80% of the
Company's estimated proved reserves were oil and approximately 63% of its total
estimated reserves were classified as proved developed. At March 31, 1998, on a
pro forma basis, the Company had interests in 1,390 producing wells of which it
operated 1,112. In fiscal year 1997, the Company had pro forma revenues and
EBITDA of $120.2 million and $61.0 million, respectively. During the first three
months of 1998, the Company had pro forma revenues and EBITDA of $25.4 million
and $11.2 million, respectively, reflecting lower prevailing oil and gas prices.
 
    The Company's Rocky Mountain activities are concentrated in the Williston
and Big Horn Basins. The Company's operations in the Williston Basin are focused
on the Cedar Hills Field, which the Company believes is, potentially, one of the
largest onshore discoveries in the lower 48 states since 1971. The Cedar Hills
Field represented approximately 45% of the PV-10 attributable to the Company's
estimated proved reserves at December 31, 1997, on a pro forma basis. In the
Williston Basin, the Company owns approximately 470,000 net leasehold acres and
has interests in 322 gross (252 net) wells, has identified 105 potential
drilling locations and conducts both primary drilling and enhanced recovery
operations. The Company recently expanded its activities into the Big Horn Basin
through the acquisition of producing and non-producing properties in the Worland
Field. The Company currently owns approximately 35,000 net leasehold acres in
the Big Horn Basin and has interests in 292 gross (125 net) producing wells
which, on a pro forma basis, represented approximately 10% of the PV-10
attributable to the Company's estimated proved reserves at December 31, 1997,
and it operates 272 of such wells. In the Big Horn Basin the Company has
identified 164 potential drilling locations which represent significant
opportunities.
 
    The Company's Mid-Continent activities are conducted primarily in the
Anadarko Basin of western Oklahoma, southwestern Kansas and the Texas Panhandle
and, to a lesser extent, in the Arkoma Basin of southeastern Oklahoma and in
southern Illinois. At December 31, 1997 the Company's Anadarko Basin properties
represented approximately 95% of the PV-10 attributable to the Company's
estimated proved reserves in the Mid-Continent and approximately 36% of the
Company's total estimated proved reserves, on a pro forma basis. In the Anadarko
Basin the Company owns approximately 57,000 net leasehold acres, has interests
in 658 gross (408 net) producing wells and has identified 11 potential drilling
locations. The Company also owns leasehold interests and expects to expand its
exploration activities in the Arkoma Basin and Gulf Coast region of Texas and
Louisiana.
 
BUSINESS STRENGTHS
 
    The Company believes that it has certain strengths that provide it with
significant competitive advantages, including the following:
 
    PROVEN GROWTH RECORD.  Continental has demonstrated consistent growth
through a balanced program of development and exploratory drilling and
acquisitions. During the five years ended December 31, 1997, the Company
increased proved reserves by 411%, production by 161% and EBITDA by 414%, on a
pro forma basis.
 
                                       45
<PAGE>
    SUBSTANTIAL DEVELOPMENT DRILLING INVENTORY.  The Company has identified over
275 potential development drilling locations based on geological and geophysical
evaluations. As of March 31, 1998, on a pro forma basis, the Company held
approximately 590,000 net acres, of which approximately 64% were classified as
undeveloped. Management believes that its current acreage holdings could support
five to seven years of drilling activities based upon oil and gas prices in
effect at March 31, 1998.
 
    LONG-LIFE NATURE OF RESERVES.  Continental's producing reserves are
primarily characterized by low rate, relatively stable, mature production that
is subject to gradual decline rates. As a result of the long-lived nature of its
properties, the Company has relatively low reinvestment requirements to maintain
reserve quantities, primary and secondary production levels and reserve values.
At December 31, 1997, on a pro forma basis, the Company's proved reserve life
index was 12.5 years.
 
    SUCCESSFUL DRILLING RECORD.  The Company has maintained a successful
drilling record. In the blanket type Red River B formation of the Williston
Basin, the Company's success rate during the three years ended December 31, 1997
was 92%, while in its other areas, the success rate was 65%, resulting in an
overall success rate of 85%. During the five years ended December 31, 1997 the
Company participated in 253 gross (175 net) wells which resulted in the addition
of 24.9 MMBoe at an average cost of $5.50 per Boe.
 
    SIGNIFICANT OPERATIONAL CONTROL.  Approximately 94% of the Company's PV-10
at December 31, 1997, on a pro forma basis, was attributable to wells operated
by the Company, giving Continental significant control over the amount and
timing of capital expenditures and production, operating and marketing
activities.
 
    TECHNOLOGICAL LEADERSHIP.  The Company has demonstrated significant
expertise in the rapidly evolving technologies of 3-D seismic evaluation and
precision horizontal drilling, and is among the few companies in North America
to successfully utilize high pressure air injection ("HPAI") enhanced recovery
technology on a large scale. Through the combination of precision horizontal
drilling and HPAI secondary recovery technology, the Company has significantly
enhanced the recoverable reserves underlying its oil and gas properties. Since
its inception, Continental has experienced a 300% to 400% increase in
recoverable reserves through use of these technologies.
 
    EXPERIENCED AND COMMITTED MANAGEMENT.  Continental's senior management team
has extensive experience in the oil and gas industry. The Chief Executive
Officer, Harold Hamm, began his career in the oil and gas industry in 1967 and
has grown Continental's revenues to $120.2 million in 1997, on a pro forma
basis. Seven senior officers have an average of 20 years of oil and gas industry
experience. Additionally, the Company's technical staff, which includes ten
petroleum engineers and ten geoscientists, has an average of over 20 years
experience in the industry.
 
BUSINESS STRATEGY
 
    The Company's strategy is to increase reserves, production and cash flow.
Key elements of the Company's strategy are:
 
    MAINTAIN A BALANCED DRILLING PROGRAM.  Continental has historically grown
through a balanced program of exploratory and development drilling and
acquisitions. Commencing in 1993, approximately 70% of wells drilled by the
Company have been development wells and the Company expects a similar balance
from its current drilling inventory. Approximately 85% of the Company's current
inventory is focused on further expansion and development of oil projects in the
Rocky Mountains, while the remainder is focused on natural gas projects in the
Mid-Continent and the Gulf Coast. The Company currently has an inventory of 275
potential development drilling locations. The Company's drilling budget for 1998
is $36.0 million, which is expected to fund the drilling of 48 gross (33.6 net)
wells; and for the three months ended March 31, 1998, the Company expended $12.9
million in drilling 15 gross (9.4 net) wells.

<PAGE>
    MAXIMIZE RESERVE RECOVERY.  The Company routinely uses advanced technology
such as precision horizontal drilling, 3-D seismic technology and HPAI
technology in its operations. Management believes that its expertise in
horizontal drilling and its record of over 20 years of successfully utilizing
HPAI technology provide the Company with a distinct competitive advantage for
its development and exploration program. Since its inception, Continental has
drilled 130 and participated in another 27 horizontal wells. The Company
currently operates four of the eight active HPAI projects in North America and
six traditional water-flood projects, and is evaluating three additional
waterflood and two additional HPAI projects, as well as approximately 185
workovers of existing wells. The Company intends to continue to apply HPAI
technology to its Cedar Hills Field and West Medicine Pole Hills properties to
maximize oil recoveries. Based on its experience in operating HPAI projects,
Continental believes that the use of HPAI technology coupled with precision
horizonal drilling in secondary recovery operations will increase total oil
recovery by 300% to 400% over average primary production, or by 50% over
secondary recovery utilizing traditional waterflooding.
 
    ACQUISITIONS OF OIL AND GAS RESERVES.  The Company focuses on acquisitions
that (i) complement its existing exploration program, (ii) provide opportunities
to utilize the Company's technological advantages, (iii) have the potential for
enhanced recovery activities, and/or (iv) provide new core areas for the
Company's operations.
 
    MAINTAIN LOW COST STRUCTURE.  The management team is committed to a low cost
structure in order to maximize cash flow and earnings. Continental has achieved
low operating and general and administrative costs through economies of scale
and geographic focus. The Company's finding costs are expected to decline over
time as the benefits of secondary recovery methods are realized.
 
    EXPAND GAS GATHERING AND MARKETING.  Continental's extensive gas gathering
infrastructure and its regional natural gas marketing operations are integral to
the Company's low cost structure and high revenues per unit of gas production.
The Company intends to expand its gas gathering systems to further improve the
rate of return on drilling and development activities and to increase the
throughput of natural gas from third parties. The gas marketing operation
provides a ready market for increased production, allowing the Company to
increase its marketing of third-party gas as well as its own production.
 
DEVELOPMENT, EXPLOITATION AND EXPLORATION ACTIVITIES
 
    DEVELOPMENT AND EXPLOITATION.  The Company's development and exploitation
activities include drilling of development wells, precision drilling of
horizontal wells, infill drilling, waterfloods, workovers, recompletions and
HPAI projects. The Company's development activities are focused primarily in the
Rocky Mountains, specifically in the Cedar Hills Field, the Medicine Pole Hills,
Buffalo, South Buffalo and West Buffalo Units in the Williston Basin and the
Worland Field in the Big Horn Basin. Approximately 85% of the Company's
development drilling inventory (275 wells) is focused on further expansion and
development of these areas. In addition, the Company is planning two HPAI oil
recovery projects and approximately 155 workovers of existing wells in the Rocky
Mountains. In the Mid-Continent, the Company is evaluating four new waterflood
projects to complement the six waterfloods it currently operates. All are oil
projects in areas where the Company has operational experience and technical

</TABLE>
 
    The Company currently anticipates that it will initiate 50 to 100
development projects in 1998. Assuming that 100 projects per year are initiated,
the Company currently has more than a five year inventory of development
projects. Continental expects to spend approximately $130 million over the next
three years for development projects.
 
    EXPLORATION ACTIVITIES.  The Company's existing inventory of exploration
projects varies in risk and reward based on their depth, location and geology.
The Company intends to use advanced technology, including 3-D seismic,
horizontal drilling and improved completion techniques, to enhance a significant
portion of the Company's existing and future exploration projects. The Company
currently estimates that it will spend $3.1 million on seismic activities over
the next three years. The Company is pursuing ten higher risk/reward exploration
prospects in the Gulf Coast and Rocky Mountains. In these ten prospects, the
Company has an inventory of 43 exploratory drilling locations in various stages
of readiness.
 
    The Gulf Coast prospects include the Jefferson Island project in Iberia
Parish, Louisiana, and the Pebble Beach project in Neuces County, Texas. The
Jefferson Island project is an underdeveloped salt dome that produces from a
series of prolific Miocene sands. To date the field has produced 22.0 MMBoe,
from approximately one quarter of the total dome. The remaining three quarters
of the dome are essentially unexplored or are underdeveloped. The Company
controls 6,283 gross (2,742 net) acres over the entire salt dome and has
identified 12 exploratory locations. The Company has an agreement with a third
party who, at its expense, acquired 35 square miles of 3-D seismic data covering
the entire salt dome, in exchange for which the third party will earn the right
to a 50% interest in the project. The 3-D data is currently being processed and
prepared for interpretation. Drilling is expected to commence in the fourth
quarter of 1998. In the Pebble Beach project, 20 square miles of 3-D seismic
data has been acquired over the project area and two wells have been drilled to
date, neither of which was commercial. Currently, there are ten additional
drilling locations in the Pebble Beach project based on 3-D seismic data.
 
    In the Rocky Mountains, the Company has identified ten exploratory
prospects, representing 21 exploratory drilling locations. In the Lustre Field
and the NE Autumn prospect of the Williston Basin, the Company owns
approximately 90,000 net leasehold acres, and intends to combine 3-D seismic and
horizontal drilling to further develop and explore for oil on this acreage.

SPECIALIZED TECHNOLOGY
 
    HORIZONTAL DRILLING OPERATIONS.  The Company's development, exploitation and
exploration activities include extensive use of precision horizontal drilling.
Through the use of precision horizontal drilling the Company has experienced a
400% to 700% increase in initial flow rates and, when coupled with HPAI
secondary recovery operations, a 300% to 400% increase in recovered reserves.
The increased recovered reserves, combined with increased production rates
offered by horizontal drilling, permitted the Company to co-discover and develop
the Cedar Hills Field from a reservoir that was historically perceived to be
non-commercial. From inception, the Company had drilled 130 horizontal wells in
the Rocky Mountains and Mid-Continent. The Company's primary horizontal drilling
objectives are non-fractured reservoirs that decline at a slower rate than
fractured reservoirs. For example, the horizontal wells in the Cedar Hills Field
have an average productive life of approximately 25 years, based solely on
primary production.
 
    HIGH PRESSURE AIR INJECTION.  The Company has successfully utilized high
pressure air injection technology to enhance the recovery of oil from its
properties in the Medicine Pole Hills, Buffalo, West Buffalo and South Buffalo
units in the Williston Basin. The Company expects to initiate HPAI in the Cedar
Hills Field and expand its use in the western part of the Medicine Pole Hills
Unit. HPAI consists of injecting compressed air into the target reservoir
through an injection well. As the compressed air is forced deeper into the
subsurface, air pressure and temperature increase, and the combination of
pressure, fuel and high temperature develops a burn front, creating gasses which
push further into the oil bearing formation. This pressure forces the oil in the
formation to move away from the pressure and, eventually, into the Company's
horizontal and vertical collector wells. In the Williston Basin, the use of HPAI
technology in secondary recovery operations, when coupled with precision
horizontal drilling, has increased total oil recovery by 300% to 400% over
average primary production, or by 50% over secondary recovery utilizing
traditional waterflooding. The Company's experience with HPAI technology has
demonstrated that production response using HPAI technology generally occurs in
one to three years, rather than five to six years using traditional
waterflooding. The Company currently conducts four of the eight active HPAI
projects in North America, the oldest of which has been operating for over 20
years.
 
ACQUISITION ACTIVITIES
 
    The Company seeks to acquire properties that have the potential to be
immediately accretive to cash flow, have long-lived, lower risk, relatively
stable production potential, and provide long-term growth in production and
reserves. The Company focuses on acquisitions that complement its existing
exploration program, provide opportunities to utilize the Company's
technological advantages, have the potential for enhanced recovery activities,
and/or provide new core areas for the Company's operations. See "--Principal Oil
and Gas Properties."

<PAGE>
PRINCIPAL OIL AND GAS PROPERTIES
 
    Until 1993, the Company's oil and gas activities were focused in the
Mid-Continent. In 1993 the Company made the strategic move to increase oil
production and reserves by expanding its development and exploration activities
into the Rocky Mountains. The Company currently controls approximately 505,000
net acres in the Rockies and is ranked among the largest oil producers in the
Rocky Mountains. Continental's oil production is characterized by long lived,
stable production with high secondary and enhanced oil recovery potential which
perpetuates production and cash flow from its properties. On a pro forma basis,
approximately 80% of its estimated proved reserves at December 31, 1997 were
oil. To achieve a more balanced reserve mix, the Company is focusing on
generating an increased inventory of natural gas drilling opportunities in the
Mid-Continent and Gulf Coast. Currently, 85% of the Company's drilling inventory
is focused on further expansion and development of its Rocky Mountain oil
fields, and the remaining 15% is focused on natural gas projects in the
Mid-Continent and Gulf Coast. The Company's Gulf Coast activities are conducted
onshore the Texas and Louisiana coasts. In the Gulf Coast, the Company holds
approximately 9,400 net leasehold acres and has identified 28 potential drilling
locations.

ROCKY MOUNTAINS
 
    The Company's Rocky Mountain properties are located primarily in the
Williston Basin of North Dakota, South Dakota and Montana and in the Big Horn
Basin of Wyoming. Estimated proved reserves for its Rocky Mountains properties
at December 31, 1997, on a pro forma basis, totaled 54.3 MMBoe and represented
62.4% of the Company's PV-10. Approximately 56.3% of these estimated proved
reserves are proved developed. During the three months ended March 31, 1998, net
daily production from these properties averaged 9,232 Bbls of oil and 1,589 Mcf
of natural gas, or 9,497 Boe per day. The Company's leasehold interests include
143,760 net developed and 361,250 net undeveloped acres, which represent 24% and
61% of the Company's total leasehold, respectively. This leasehold is expected
to be developed utilizing 3-D seismic, precision horizontal drilling and HPAI,
where applicable. As of June 30, 1998, the Company's Rocky Mountain properties
included an inventory of 248 development and 21 exploratory drilling locations.
 
WILLISTON BASIN
 
    CEDAR HILLS FIELD.  The Cedar Hills Field was discovered in November 1994
and is still under development. During the three months ended March 31, 1998,
the Cedar Hills Field properties produced 6,569 net Bbls per day to the Company
interests and represented 45% of the PV-10 attributable to the Company's
estimated proved reserves as of December 31, 1997 on a pro forma basis. The
Cedar Hills Field produces oil from the Red River "B" Formation, a thin (eight
feet), non-fractured, blanket-type, dolomite

reservoir found at depths of 8,000 to 9,500 feet. All wells drilled by the
Company in the Red River "B" Formation were drilled exclusively with precision
horizontal drilling technology. The Cedar Hills Field covers approximately 200
square miles and has a known oil column of 1,000 feet. Through March 31, 1998,
the Company drilled or participated in 139 gross (91 net) horizontal wells, of
which 132 were successfully completed, for a 92% net success rate.
 
    The Company believes that the Red River "B" formation in the Cedar Hills
Field is well suited for enhanced secondary recovery using HPAI technology. On
four nearby HPAI projects operated by the Company, HPAI technology has increased
oil recoveries 200% to 300% over primary recovery with ultimate recoveries
reaching up to 40% of the original oil in place. The Company intends to initiate
installation of HPAI secondary recovery on certain of its Cedar Hills Field
properties upon completion of field unitization, which is expected to occur in
1999. The Company believes that HPAI could increase its total recovery from the
Cedar Hills Field by as much as 75 million net barrels. On May 15, 1998, the
Company and an unrelated joint interest owner entered into a definitive
agreement to exchange undivided interests so that effective December 1, 1998 the
Company will own working interests ranging from 90% to 92% in approximately
65,000 gross (59,000 net) leasehold acres in the northern half of the Cedar
Hills Field. As a result, the Company will enhance its ability to unitize all
interests in the northern half of the Cedar Hills Field, which is necessary in
order for the Company to initiate the planned HPAI enhanced recovery operations
in the Cedar Hills Field.
 
    As of June 30, 1998, there are 18 horizontal drilling locations in
inventory, all of which are development well locations.
 
    MEDICINE POLE HILLS, BUFFALO, WEST BUFFALO AND SOUTH BUFFALO UNITS.  In
1995, the Company acquired the following interests in four production units in
the Williston Basin: Medicine Pole Hills (63%); Buffalo (86%); West Buffalo
(82%); and South Buffalo (85%). During the three months ended March 31, 1998,
these units produced 2,275 Bbls per day, net to the Company's interests, and
represented 4.6 MMBoe or 7% of the pro forma PV-10 attributable to the Company's
estimated proved reserves as of December 31, 1997. These units are HPAI enhanced
recovery projects that produce from the Red River "B" Formation and are operated
by the Company. These units were discovered and developed with conventional
vertical drilling. The oldest vertical well in these units has been producing
for 44 years, demonstrating the long lived production characteristic of the Red
River "B" Formation. There are 104 producing wells in these units and current
estimates of remaining reserve life range from four to 16 years. The Company
plans to further develop these units and enhance production by drilling
strategically placed horizontal wells. There are currently 54 development
drilling locations identified in these units.
 
    LUSTRE AND MIDFORK FIELDS.  In January 1992, the Company acquired the Lustre
and Midfork Fields which, during the three months ended March 31, 1998, produced
369 Bopd to the Company's interests and represented 0.6 MMBoe or 1% of the pro
forma PV-10 attributable to its estimated proved reserves as of December 31,
1997. Wells in both the Lustre and Midfork Fields produce from the Charles "C"
dolomite, at depths of 5,500 to 6,000 feet. Historically, production from the
Charles "C" has a low daily production rate and is long lived. There are
currently 37 wells producing in the two fields, and no secondary recovery is
underway in either field. The Company currently owns 90,000 net acres in the
Lustre and Midfork Fields and plans to utilize 3-D seismic combined with
horizontal drilling to further exploit the Charles "C" reservoir, and to
generate drilling opportunities for deeper objectives underlying the Lustre and
Midfork Fields as well as guide exploration for new fields on its substantial
undeveloped leasehold.
 
BIG HORN BASIN
 
    WORLAND FIELD.  On May 14, 1998, the Company consummated the purchase for
$86.5 million of producing and non-producing oil and gas properties and certain
other related assets in the Worland Field, effective as of June 1, 1998.
Subsequently, and effective as of June 1, 1998, the Company sold an undivided
50% interest in the Worland Field properties (excluding inventory and certain
equipment) to the
 
                                       51
<PAGE>
Company's principal shareholder for $42.6 million. See "Certain Relationships
and Related Transactions." The Worland Field properties cover 35,000 net
leasehold acres in the Worland Field of the Big Horn Basin in northern Wyoming,
of which 22,753 net acres are held by production and 12,135 net acres are non-
producing or prospective. Approximately two-thirds of the Company's producing
leases in the Worland Field are within five federal units, the largest of which
(the Cottonwood Creek Unit) has been producing for over 40 years. All of the
units produce principally from the Phosphoria formation, which is the most
prolific oil producing formation in the Worland Field. Four of the units are
unitized as to all depths, with the Cottonwood Creek Field Extension
(Phosphoria) Unit being unitized only as to the Phosphoria formation. The
Company is the operator of all five of the federal units. The Company also
operates 40 of the 60 producing wells located on non-unitized acreage. The
Company's Worland Field properties include interests in 292 producing wells, 272
of which are operated by the Company.
 
    As of December 31, 1997, the estimated net proved reserves attributable to
the Company's Worland Field properties were approximately 32.0 MMBoe, with an
estimated PV-10 of $25.4 million. Approximately 85% of these proved reserves
consist of oil, principally in the Phosphoria formation. Oil produced from the
Company's Worland Field properties is low gravity, sour (high sulphur content)
crude, resulting in a lower sales price per barrel than non-sour crude, and is
sold into a Marathon pipeline or is trucked from the lease. Gas produced from
the Worland Field properties is also sour, resulting in a sale price that is
less per Mcf than non-sour natural gas.
 
    In addition to the proved reserves, the Company has identified 158 locations
on its Worland Field properties, to further develop and exploit the undeveloped
portion of the Worland Field. Over 100 wells have been identified for acid
fracture stimulation, most of which have been classified as having proved
developed non-producing reserves. The Company believes that secondary and
tertiary recovery projects will have significant potential for the addition of
reserves. In addition, six drilling prospects have been identified on the
Company's Worland Field properties in which prospects the Company and its
principal shareholder, together, have a majority leasehold position, allowing
for further exploration for and exploitation of the Phosphoria, Tensleep,
Frontier and Muddy formations and other prospective formations for additional
reserves.
 
MID-CONTINENT
 
    The Company's Mid-Continent properties are located primarily in the Anadarko
Basin of western Oklahoma, southwestern Kansas and the Texas Panhandle, and to a
lesser extent, in the Arkoma Basin of southeastern Oklahoma ("Arkoma Basin"),
and in southern Illinois. At December 31, 1997, the Company's estimated proved
reserves in the Mid-Continent totaled 10.6 MMBoe, representing 37.4% of the
Company's PV-10 at such date, on a pro forma basis, and 97% of these reserves
were proved developed. At such date, approximately 70% of the Company's
estimated proved reserves in the Mid-Continent were natural gas. Net daily
production from these properties during the first quarter of 1998 averaged 1,374
Bbls of oil and 14,094 Mcf of natural gas, or 3,723 Boe to the Company's
interests. The Company's Mid-Continent leasehold position includes 64,536 net
developed and 10,853 net undeveloped acres, representing 11% and 2% of the
Company's total pro forma leasehold, respectively, at March 31, 1998.
 
    As of June 30, 1998, the Company's Mid-Continent properties included an
inventory of 21 development drilling locations, 11 of which were in the Anadarko
Basin.
 
    ANADARKO BASIN.  The Anadarko Basin properties contained 95% of the
Company's estimated proved reserves for the Mid-Continent and 35.6% of the
Company's total PV-10 at December 31, 1997, on a pro forma basis, and at such
date, represented 53% of the Company's estimated proved reserves of natural gas.
During the three months ended March 31, 1998, net daily production from its
Anadarko Basin properties averaged 1,258 Bbls of oil and 12,684 Mcf of natural
gas, or 3,372 Boe to the Company's interest from 658 gross (408 net) producing
wells, 507 of which are operated by the Company. The Anadarko Basin wells
produce from a variety of sands and carbonates in both stratigraphic and
structural traps in the Arbuckle,
 
                                       52
<PAGE>
Oil Creek, Viola, Mississippian, Springer, Morrow, Red Ford, Oswego, Skinner and
Tonkawa formations, at depths ranging from 6,000 to 12,000 feet. These
properties are currently being re-evaluated for further development drilling and
workover potential.
 
    OTHER MID-CONTINENT PROPERTIES.  The Company's remaining Mid-Continent
properties include those located in the Arkoma Basin and in southern Illinois.
In the Arkoma Basin, the Company is focused on coal bed methane, where it owns
approximately 14,000 acres and has 43 producing wells from the Hartshorne coal
at depths of 2,500 to 3,500 feet. The Company plans to drill two pilot
horizontal tests in the coal in 1998. In Illinois, the Company participates with
another operator in two waterflood projects and up to three wells per year for
production from shallow Mississippian age sands and carbonates.

OIL AND GAS RESERVES
 
    The following table summarizes the estimates of the Company's net proved
reserves and the related PV-10 of such reserves at the dates shown. Ryder Scott
Company Petroleum Engineers ("Ryder Scott") prepared the reserve and present
value data with respect to the Company's oil and gas properties which
represented 72% of the PV-10 at December 31, 1997 and Worland Field properties
which represented 77% of the PV-10 of the Worland Field properties at the same
date. The Company prepared the reserve and present value data on all other
Company and Worland Field properties.

(1) Pro forma to reflect the Worland Field Acquisition as if it had occurred on
    December 31, 1997.
 
(2) PV-10 represents the present value of estimated future net cash flows before
    income tax discounted at 10% using prices in effect at the end of the
    respective periods presented and including the effects of hedging
    activities. In accordance with applicable requirements of the Commission,
    estimates of the Company's proved reserves and future net cash flows are
    made using oil and gas sales prices estimated to be in effect as of the date
    of such reserve estimates and are held constant throughout the life of the
    properties (except to the extent a contract specifically provides for
    escalation). The prices used in calculating PV-10 as of December 31, 1997
    were $18.06 per Bbl of oil and $2.25 per Mcf of natural gas. The average
    prices used in calculating the pro forma PV-10 as of December 31, 1997 were
    $14.59 per Bbl of oil and $2.07 per Mcf of natural gas. Average prices as of
    May 31, 1998, on a pro forma basis, were $11.86 per Bbl of oil and $1.68 per
    Mcf of natural gas. These prices, if applied to estimated proved reserves of
    the Company as of December 31, 1997, would result in a PV-10, on a pro forma
    basis, of $170.0 million at such date, as estimated by the Company.
 
(3) In 1996, the Company changed its fiscal year-end from May 31 to December 31.
    Because reports on a December 31 year-end basis prior to 1996 were not
    available, information as of December 31, 1995 was determined from the
    Company's production, drilling, acquisition and sale data as applied to its
    December 31, 1996 reserve report.
 
    Estimated quantities of proved reserves and future net cash flows therefrom
are affected by oil and gas prices, which have fluctuated widely in recent
years. There are numerous uncertainties inherent in estimating oil and gas
reserves and their values, including many factors beyond the control of the
producer. The reserve data set forth in this Prospectus represent only
estimates. Reservoir engineering is a subjective process of estimating
underground accumulations of oil and gas that cannot be measured in an exact
manner. The accuracy of any reserve estimate is a function of the quality of
available data and of engineering and geological interpretation and judgment. As
a result, estimates of different engineers,
 
                                       55
<PAGE>
including those used by the Company, may vary. In addition, estimates of
reserves are subject to revision based upon actual production, results of future
development and exploration activities, prevailing oil and gas prices, operating
costs and other factors, which revisions may be material. Accordingly, reserve
estimates are often different from the quantities of oil and gas that are
ultimately recovered. The meaningfulness of such estimates is highly dependent
upon the accuracy of the assumptions upon which they are based.
 
    In general, the volume of production from oil and gas properties declines as
reserves are depleted. Except to the extent the Company acquires properties
containing proved reserves or conducts successful exploitation and development
activities, the proved reserves of the Company will decline as reserves are
produced. The Company's future oil and gas production is, therefore, highly
dependent upon its level of success in finding or acquiring additional reserves.
See "Risk Factors--Replacement of Reserves" and "--Uncertainty of Estimates of
Oil and Gas Reserves and Future Net Cash Flows."
 
GAS GATHERING SYSTEMS
 
    The Company's gas gathering systems are owned by CGI. Natural gas and
casinghead gas are purchased at the wellhead primarily under either
market-sensitive percent-of-proceeds-index contracts or keep-whole gas purchase
contracts. Under percent-of-proceeds-index contracts, CGI receives a fixed
percentage of the monthly index posted price for natural gas and a fixed
percentage of the resale price for natural gas liquids. CGI generally receives
between 20% and 30% of the posted index price for natural gas sales and from 20%
to 30% of the proceeds received from natural gas liquids sales. Under keep-whole
gas purchase contracts, CGI retains all natural gas liquids recovered by its
processing facilities and keeps the producers whole by returning to the
producers at the tailgate of its plants an amount of residue gas equal on a BTU
basis to the natural gas received at the plant inlet. The keep-whole component
of the contract permits the Company to benefit when the value of natural gas
liquids is greater as a liquid than as a portion of the residue gas stream.
 
OIL AND GAS MARKETING
 
    The Company's oil and gas production is sold primarily under market
sensitive or spot price contracts. The Company sells substantially all of its
casinghead gas to purchasers under varying percentage-of-proceeds contracts. By
the terms of these contracts, the Company receives a fixed percentage of the
resale price received by the purchaser for sales of natural gas and natural gas
liquids recovered after gathering and processing the Company's gas. The Company
normally receives between 80% and 100% of the proceeds from natural gas sales
and from 80% to 100% of the proceeds from natural gas liquids sales received by
the Company's purchasers when the products are resold. The natural gas and
natural gas liquids sold by these purchasers are sold primarily based on spot
market prices. The revenues received by the Company from the sale of natural gas
liquids is included in natural gas sales. As a result of the natural gas liquids
contained in the Company's production, the Company has historically improved its
price realization on its natural gas sales as compared to Henry Hub or other
natural gas price indexes. For the year ended December 31, 1997, purchases of
the Company's natural gas production by GPM Gas Corporation, Warren NGL, Inc.,
and Oklahoma Natural Gas Company accounted for 14.7%, 12.7% and 12.6% of the
Company's total gas sales for such period, respectively. For the year ended
December 31, 1997, purchases of the Company's oil production by Koch Oil Company
and Sun Oil Company accounted for 74.2% and 10.0% of the Company's total oil
sales for such period. Due to the availability of other markets, the Company
does not believe that the loss of Koch Oil Company or any other crude oil or gas
customer would have a material adverse effect on the Company's results of
operations.
 
    Periodically the Company utilizes various hedging strategies to hedge the
price of a portion of its future oil and gas production. The Company does not
establish hedges in excess of its expected production. These strategies
customarily emphasize forward-sale, fixed-price contracts for physical delivery
of a specified quantity of production or swap arrangements that establish an
index-related price above which
 
                                       56
<PAGE>
the Company pays the hedging partner and below which the Company is paid by the
hedging partner. These contracts allow the Company to predict with greater
certainty the effective oil and gas prices to be received for its hedged
production and benefit the Company when market prices are less than the fixed
prices provided in its forward-sale contracts. However, the Company does not
benefit from market prices that are higher than the fixed prices in such
contracts for its hedged production. As of March 31, 1998, no forward-sale
contracts were in place with respect to the Company's future production from
proved natural gas reserves.
 
EMPLOYEES
 
    As of July 31, 1998, the Company employed 205 people, 79 of which were
administrative personnel, [14] of which were geological personnel, 14 of which
were engineers and the remainder were field personnel. The Company's future
success will depend partially on its ability to attract, retain and motivate
qualified personnel. The Company is not a party to any collective bargaining
agreements and has not experienced any strikes or work stoppages. The Company
considers its relations with its employees to be satisfactory.
 
COMPETITION
 
    The oil and gas industry is highly competitive. The Company competes for the
acquisition of oil and gas properties, primarily on the basis of the price to be
paid for such properties, with numerous entities including major oil companies,
other independent oil and gas concerns and individual producers and operators.
Many of these competitors are large, well established companies and have
financial and other resources substantially greater than those of the Company.
The Company's ability to acquire additional oil and gas properties and to
discover reserves in the future will depend upon its ability to evaluate and
select suitable properties and to consummate transactions in a highly
competitive environment.
 
LEGAL PROCEEDINGS
 
    From time to time, the Company is party to litigation or other legal
proceedings that it considers to be a part of the ordinary course of its
business. The Company is not involved in any legal proceedings nor is it party
to any pending or threatened claims that could reasonably be expected to have a
material adverse effect on its financial condition or results of operations.
 
REGULATION
 
    GENERAL.  Various aspects of the Company's oil and gas operations are
subject to extensive and continually changing regulation, as legislation
affecting the oil and gas industry is under constant review for amendment or
expansion. Numerous departments and agencies, both federal and state, are
authorized by statute to issue, and have issued, rules and regulations binding
upon the oil and gas industry and its individual members.
 
    REGULATION OF SALES AND TRANSPORTATION OF NATURAL GAS.  The Federal Energy
Regulatory Commission (the "FERC") regulates the transportation and sale for
resale of natural gas in interstate commerce pursuant to the Natural Gas Act of
1938 and the Natural Gas Policy Act of 1978. In the past, the federal government
has regulated the prices at which oil and gas could be sold. While sales by
producers of natural gas and all sales of crude oil, condensate and natural gas
liquids can currently be made at uncontrolled market prices, Congress could
reenact price controls in the future. The Company's sales of natural gas are
affected by the availability, terms and cost of transportation. The price and
terms for access to pipeline transportation are subject to extensive regulation
and proposed regulation designed to increase competition within the natural gas
industry, to remove various barriers and practices that historically limited
non-pipeline natural gas sellers, including producers, from effectively
competing with interstate pipelines for sales to local distribution companies
and large industrial and commercial customers and to establish the
 
                                       57
<PAGE>
rates interstate pipelines may charge for their services. Similarly, the
Oklahoma Corporation Commission and the Texas Railroad Commission have been
reviewing changes to their regulations governing transportation and gathering
services provided by intrastate pipelines and gatherers. While the changes being
considered by these federal and state regulators would affect the Company only
indirectly, they are intended to further enhance competition in natural gas
markets. The Company cannot predict what further action the FERC or state
regulators will take on these matters, however, the Company does not believe
that any actions taken will have an effect materially different than the effect
on other natural gas producers with which it competes.
 
    Additional proposals and proceedings that might affect the natural gas
industry are pending before Congress, the FERC, state commissions and the
courts. The natural gas industry historically has been very heavily regulated;
therefore, there is no assurance that the less stringent regulatory approach
recently pursued by the FERC and Congress will continue.
 
    OIL PRICE CONTROLS AND TRANSPORTATION RATES.  Sales of crude oil, condensate
and gas liquids by the Company are not currently regulated and are made at
market prices. The price the Company receives from the sale of these products
may be affected by the cost of transporting the products to market.
 
    ENVIRONMENTAL.  Extensive federal, state and local laws regulating the
discharge of materials into the environment or otherwise relating to the
protection of the environment affect the Company's oil and gas operations.
Numerous governmental departments issue rules and regulations to implement and
enforce such laws, which are often difficult and costly to comply with and which
carry substantial civil and even criminal penalties for failure to comply. Some
laws, rules and regulations relating to protection of the environment may, in
certain circumstances, impose strict liability for environmental contamination,
rendering a person or entity liable for environmental damages and cleanup costs
without regard to negligence or fault on the part of such person or entity.
Other laws, rules and regulations may restrict the rate of oil and gas
production below the rate that would otherwise exist or even prohibit
exploration and production activities in sensitive areas. In addition, state
laws often require various forms of remedial action to prevent pollution, such
as closure of inactive pits and plugging of abandoned wells. The regulatory
burden on the oil and gas industry increases the Company's cost of doing
business and consequently affects the Company's profitability. The Company
believes that it is in substantial compliance with current applicable
environmental laws and regulations and that continued compliance with existing
requirements will not have a material adverse impact on the Company's
operations. However, environmental laws and regulations have been subject to
frequent changes over the years, and the imposition of more stringent
requirements could have a material adverse effect upon the capital expenditures
or competitive position of the Company.
 
    The Company currently owns or leases, and has in the past owned or leased,
numerous properties that have been used for the exploration and production of
oil and gas and for other uses associated with the oil and gas industry.
Although the Company followed operating and disposal practices that it
considered appropriate under applicable laws and regulations, hydrocarbons or
other wastes may have been disposed of or released on or under the properties
owned or leased by the Company or on or under other locations where such wastes
were taken for disposal. In addition, the Company owns or leases properties that
have been operated by third parties in the past. The Company could incur
liability under the Comprehensive Environmental Response, Compensation and
Liability Act or comparable state statutes for contamination caused by wastes it
generated or for contamination existing on properties it owns or leases, even if
the contamination was caused by the waste disposal practices of the prior owners
or operators of the properties. In addition, it is not uncommon for landowners
and other third parties to file claims for personal injury and property damage
allegedly caused by the release of produced fluids or other pollutants into the
environment.
 
    The Federal Solid Waste Disposal Act, as amended by the Resource
Conservation and Recovery Act of 1976 ("RCRA"), regulates the generation,
transportation, storage, treatment and disposal of hazardous
 
                                       58
<PAGE>
wastes and can require cleanup of hazardous waste disposal sites. RCRA currently
excludes drilling fluids, produced waters and certain other wastes associated
with the exploration, development or production of oil and gas from regulation
as "hazardous waste." A similar exemption is contained in many of the state
counterparts to RCRA. Disposal of such oil and gas exploration, development and
production wastes usually is regulated by state law. Other wastes handled at
exploration and production sites or used in the course of providing well
services may not fall within this exclusion. Moreover, stricter standards for
waste handling and disposal may be imposed on the oil and gas industry in the
future. From time to time legislation has been proposed in Congress that would
revoke or alter the current exclusion of exploration, development and production
wastes from the RCRA definition of "hazardous wastes" thereby potentially
subjecting such wastes to more stringent handling and disposal requirements. If
such legislation were enacted, or if changes to applicable state regulations
required the wastes to be managed as hazardous wastes, it could have a
significant impact on the operating costs of the Company, as well as the oil and
gas industry in general.
 
    The Company's operations are also subject to the Clean Air Act (the "CAA")
and comparable state and local requirements. Amendments to the CAA were adopted
in 1990 and contain provisions that may result in the gradual imposition of
certain pollution control requirements with respect to air emissions from
operations of the Company. The Company may be required to incur certain capital
expenditures in the next several years for air pollution control equipment in
connection with obtaining and maintaining operating permits and approvals for
air emissions. However, the Company believes its operations will not be
materially adversely affected by any such requirements, and the requirements are
not expected to be any more burdensome to the Company than to other similarly
situated companies involved in oil and gas exploration and production activities
or well servicing activities.
 
    The Federal Water Pollution Control Act of 1972 (the "FWPCA") imposes
restrictions and strict controls regarding the discharge of wastes, including
produced waters and other oil and gas wastes, into navigable waters. These
controls have become more stringent over the years, and it is probable that
additional restrictions will be imposed in the future. Permits must be obtained
to discharge pollutants into state and federal waters. The FWPCA provides for
civil, criminal and administrative penalties for unauthorized discharges of oil
and other hazardous substances and imposes substantial potential liability for
the costs of removal or remediation. State laws governing discharges to water
also provide varying civil, criminal and administrative penalties and impose
liabilities in the case of a discharge of petroleum or its derivatives, or other
hazardous substances, into state waters. In addition, the Environmental
Protection Agency has promulgated regulations that require many oil and gas
production sites, as well as other facilities, to obtain permits to discharge
storm water runoff. The Company believes that compliance with existing
requirements under the FWPCA and comparable state statutes will not have a
material adverse effect on the Company's financial condition or results of
operations.
 
    REGULATION OF OIL AND GAS EXPLORATION AND PRODUCTION.  Exploration and
production operations of the Company are subject to various types of regulation
at the federal, state and local levels. Such regulations include requiring
permits and drilling bonds for the drilling of wells, regulating the location of
wells, the method of drilling and casing wells, and the surface use and
restoration of properties upon which wells are drilled. Many states also have
statutes or regulations addressing conservation matters, including provisions
for the utilization or pooling of oil and gas properties, the establishment of
maximum rates of production from oil and gas wells and the regulation of
spacing, plugging and abandonment of such wells. Some state statutes limit the
rate at which oil and gas can be produced from the Company's properties. See
"Risk Factors--Laws and Regulations; Environmental Risk."
 
TITLE TO PROPERTIES
 
    The Company believes it has satisfactory title to all of its properties in
accordance with standards generally accepted in the oil and gas industry. As is
customary in the oil and gas industry, the Company makes only a cursory review
of title to farmout acreage and to undeveloped oil and gas leases upon
 
                                       59
<PAGE>
execution of any contracts. Prior to the commencement of drilling operations, a
title examination is conducted and curative work is performed with respect to
significant defects. To the extent title opinions or other investigations
reflect title defects, the Company, rather than the seller of the undeveloped
property, is typically responsible to cure any such title defects at its
expense. If the Company were unable to remedy or cure any title defect of a
nature such that it would not be prudent to commence drilling operations on the
property, the Company could suffer a loss of its entire investment in the
property. The Company has obtained title opinions on substantially all of its
producing properties. Prior to completing an acquisition of producing oil and
gas leases, the Company performs a title review on a material portion of the
leases. The Company's oil and gas properties are subject to customary royalty
interests, liens for current taxes and other burdens that the Company believes
do not materially interfere with the use of or affect the value of such
properties.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
    Continental does not have a separate compensation committee of its board of
directors. The board of directors sets the compensation for its executive
officers and Harold Hamm, Chairman of the Board and President, is a director and
participates in these deliberations concerning executive officer compensation.
Each of the directors of Continental also serve on the board of directors of
subsidiaries of Continential. As such, each of the directors participates in the
deliberations concerning executive officers' compensation for Continential and
its subsidiaries.
 
EMPLOYMENT AGREEMENTS
 
    The Company does not have any employment agreeements with its named
Executive Officers.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
    Set forth below is a description of transactions entered into between the
Company and certain of its officers, directors, employees and stockholders since
January 1, 1995. Certain of these transactions will continue in the future and
may result in conflicts of interest between the Company and such individuals,
and there can be no assurance that conflicts of interest will always be resolved
in favor of the Company.
 
    OIL AND GAS OPERATIONS.  In its capacity as operator of certain oil and gas
properties, the Company obtains oilfield services from related companies. These
services include leasehold acquisition, well location, site construction and
other well site services, saltwater trucking, use of rigs for completion and
workover of oil and gas wells and the rental of oil field tools and equipment.
Harold Hamm is the chief executive officer and principal shareholder of each of
these related companies. The aggregate amounts paid by Continental to these
related companies during 1995, 1996, 1997 and during the three months ended
March 31, 1998 were $5.9 million, $5.9 million, $11.9 million, and $3.5 million,
respectively. The total amount paid to these affiliated companies, a portion of
which is billed to other interest owners, was approximately $11.9 million in
1997. The services discussed above were provided at costs and upon terms that
management believes are no less favorable to the Company than could have been
obtained from unrelated parties. In addition, Harold Hamm and certain companies
controlled by him own interests in wells operated by the Company. At December
31, 1997 and March 31, 1998, the Company owed such persons an aggregate of
$200,000 and $100,000, respectively, representing their shares of oil and gas
production sold by the Company.
 
    SHAREHOLDER LOANS AND ADVANCES.  In 1997 and 1998, the Company obtained
loans and advances from Harold Hamm and certain of his affiliates. Such loans
and advances were unsecured and were repaid from time to time in varying
amounts, with interest at an annual rate of 8.25%. The maximum aggregate amount
of such loans and advances outstanding at any time during 1997 and during the
three months ended March 31, 1998 was $22.0 million and $24.4 million,
respectively. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations--Liquidity and Capital Resources."
 
    OFFICE LEASE.  The Company leases office space under operating leases
directly or indirectly from Harold Hamm and Continental Management Company,
L.L.C., a Company owned in part by Harold Hamm. In 1997, the Company paid rents
associated with these leases of approximately $294,000.
 
    PARTICIPATION IN WELLS.  Certain officers and directors of the Company have
participated and may participate in the future in wells drilled by the Company.
In 1997, Harold Hamm participated in Company wells on terms similar to those
available to unrelated third parties and was billed an aggregate of $515,000,
for his share of drilling, completion, equipping and operating costs. At
December 31, 1997, the aggregate unpaid balance owed to the Company by such
officers and directors was $4,565, none of which was past due.
 
    Effective June 1, 1998, the Company sold an undivided 50% interest in the
70,000 net leasehold acres it acquired in the Worland Field Acquisition to its
principal shareholder, Harold Hamm. The Worland Field sale did not include
inventory and certain items of equipment which the Company had acquired in the
Worland Field Acquisition. The $42.6 million purchase price paid by Harold Hamm
equals the Company's cost basis in such leasehold acres. Harold Hamm paid $19.3
million of the purchase price in cash and the balance of $23.3 million by the
cancellation of indebtedness owed by Harold Hamm to the Company. Harold Hamm is
subject to the applicable unit agreements in place with respect to his interests
in the Worland Field. Harold Hamm intends to sell some or all of the interests
acquired from the Company, although no arrangements, understandings or
agreements for any such sale currently exist.
 
                             PRINCIPAL SHAREHOLDERS
 
    Harold Hamm, Chairman of the Board, President and Chief Executive Officer
and a Director of the Company beneficially owns 44,496 shares (90.7%) of the
Company's outstanding common stock. The remaining 4,545 shares (9.3%) of the
outstanding common stock is beneficially owned by the Harold Hamm Delta Trust,
an irrevocable trust over which Harold Hamm has no voting or investment power.

                         DESCRIPTION OF CREDIT FACILITY
 
    The following summary of the Credit Facility does not purport to be complete
and is subject to, and qualified in its entirety by reference to, the Credit
Facility. Bank One, Oklahoma, N.A., as agent for the lenders under the Credit
Facility ("Agent"), has consented to the terms of the Indenture and the issuance
of the Notes.
 
    At July 31, 1998, $4.0 million was outstanding under the Credit Facility.
The Credit Facility is payable in full on May 14, 2001. All amounts outstanding
under the Credit Facility are secured by a first lien on substantially all of
the Company's proved oil and gas reserves, wells, systems, plants, related
personal property and contract rights.
 
    INTEREST AND FEES.  Amounts advanced under the Credit Facility bear interest
determined with reference to a sliding scale that takes into account the ratio
of the aggregate amount outstanding to the Borrowing Base (as defined in the
Credit Facility). The applicable rate may, at the Company's option, be based
either on the LIBOR rate or the Agent's prime rate. The rates range from the
LIBOR rate plus a margin of 100 to 175 basis points, or the Agent's prime rate
with no margin. The Company pays a non-use fee of 0.1875% to 0.25% per annum on
the amount by which the Borrowing Base exceeds the aggregate amount outstanding,
and an agency fee equal to $50,000 per annum.
 
    BORROWING BASE.  The amount of credit available at any time under the Credit
Facility is the lesser of the commitment amount or the Borrowing Base. The
commitment amount, initially, was $175.0 million. Upon completion of the
Offering and application of the net proceeds therefrom, the commitment amount
and the Borrowing Base was reduced to $75.0 million. The Borrowing Base is
redetermined semi-annually by the banks and may be redetermined more frequently
at the request of the Company, the Agent or banks holding 66 2/3% of the
outstanding balance under the Credit Facility. To the extent the amount
outstanding under the Credit Facility exceeds the Borrowing Base, the Company
must either reduce the amount outstanding or furnish additional collateral. At
June 30, 1998, the Borrowing Base was $175.0 million, which was more than the
amount outstanding under the Credit Facility at that date. The next scheduled
Borrowing Base redetermination date will be November 1, 1998.
 
    COVENANTS.  The Credit Facility contains customary affirmative and
restrictive covenants which, among other things, require periodic financial and
reserve reporting, require that the Company not allow the ratio of its
indebtedness to tangible net worth to exceed 3.25 to 1 as of the end of any
fiscal quarter, require that the Company not allow its minimum debt service
coverage ratio to be less than 1.2 to 1 as of the end of any fiscal quarter for
the immediately preceding four quarters, maintain a current ratio of at least
1.0 to 1 at the end of any fiscal quarter, and limit the Company and its
Restricted Subsidiaries with respect to indebtedness, liabilities, liens,
dividends, loans, lines of business, transactions with affiliates, changes in
management, investments, amendments to organizational documents, purchases and
sales of assets and speculative trading activities, unless the requisite number
of banks otherwise consent.
 
    EVENTS OF DEFAULT.  The Credit Facility contains customary events of
default, including, among other things and subject to applicable grace periods,
payment defaults, material misrepresentations, covenant defaults, certain
bankruptcy events, and judgment defaults. It also is an event of default under
the Credit Facility if any indebtedness of the Company or the Restricted
Subsidiaries in excess of $250,000, including the Notes, is accelerated or if a
change in management occurs.

<PAGE>
                              DESCRIPTION OF NOTES
 
GENERAL
 
    The Old Notes were issued pursuant to the Indenture among the Company, the
Subsidiary Guarantors and United States Trust Company of New York, as trustee
(the "Trustee"). The New Notes will be issued under the Indenture, which will be
subject to the Trust Indenture Act of 1939, as amended (the "Trust Indenture
Act"). As used herein the term "Notes" includes the Old Notes and the New Notes.
The terms of the Notes include those stated in the Indenture and those made part
of the Indenture by reference to the Trust Indenture Act. The Notes are subject
to all such terms, and Holders of the Notes are referred to the Indenture and
the Trust Indenture Act for a statement thereof. The following summary of
certain provisions of the Indenture does not purport to be complete and is
qualified in its entirety by reference to the Indenture, including the
definitions therein of certain terms used below. The definitions of certain
terms used in the following summary are set forth below under "--Certain
Definitions."
 
    The Notes will be general unsecured obligations of the Company and will be
subordinated in right of payment to Senior Debt. The Notes will be guaranteed on
a senior subordinated basis by each Restricted Subsidiary of the Company and any
future Restricted Subsidiary of the Company. The obligations of the Subsidiary
Guarantors under the Subsidiary Guarantees will be general unsecured obligations
of each of the Subsidiary Guarantors and will be subordinated in right of
payment to all obligations of the Subsidiary Guarantors in respect of Guarantor
Senior Debt. See "--Subsidiary Guarantees" and "Risk Factors-- Subordination of
Notes and Guarantees."
 
    For purposes of this section, the term "Company" means Continental
Resources, Inc. As of the date of the Indenture, all of the Company's
Subsidiaries will be Restricted Subsidiaries. Under certain circumstances,
however, the Company will be able to designate current and future Subsidiaries
as Unrestricted Subsidiaries. Unrestricted Subsidiaries will not be subject to
many of the restrictive covenants set forth in the Indenture. See "--Certain
Covenants."
 
TERMS OF THE NOTES
 
    The Notes are limited in aggregate principal amount to $150 million and will
mature on August 1, 2008. Interest on the Notes will accrue at the rate of
10 1/4% per annum and will be payable semi-annually in arrears on February 1 and
August 1 of each year, commencing February 1, 1999, to Holders of the Notes of
record on the immediately preceding January 15 and July 15. Interest on the
Notes will accrue from the most recent date on which interest has been paid or,
if no interest has been paid, from the date of original issuance.
 
    Interest will be computed on the basis of a 360-day year comprised of twelve
30-day months. Principal, premium, if any, and interest on the Notes will be
payable at the office or agency of the Company maintained for such purpose
within the City and State of New York or, at the option of the Company, payment
of interest may be made by check mailed to the Holders of the Notes at their
respective addresses set forth in the applicable register of Holders of the
Notes. Until otherwise designated by the Company, the Company's office or agency
in New York will be the office of the Trustee maintained for such purpose. The
Notes will be fully registered as to principal and interest in minimum
denominations of $1,000 and integral multiples of $1,000 in excess thereof.
 
OPTIONAL REDEMPTION
 
    Except as otherwise described below, the Notes will not be redeemable at the
Company's option prior to August 1, 2003. Thereafter, the Notes will be subject
to redemption at the option of the Company, in whole or in part, upon not less
than 30 nor more than 60 days' notice, at the redemption prices (expressed as
percentages of principal amount) set forth below plus accrued and unpaid
interest thereon to the

    Prior to August 1, 2001, the Company may, at its option, on any one or more
occasions, redeem up to 35% of the original aggregate principal amount of the
Notes at a redemption price equal to 110.25% of the principal amount thereof,
plus accrued and unpaid interest, if any, thereon to the redemption date, with
all or a portion of the net proceeds of public sales of common stock of the
Company; PROVIDED that at least 65% of the original aggregate principal amount
of the Notes remains outstanding immediately after the occurrence of such
redemption; and PROVIDED, FURTHER, that such redemption shall occur within 60
days of the date of the closing of the related sale of common stock of the
Company.
 
    At any time on or prior to August 1, 2003, the Notes may also be redeemed as
a whole at the option of the Company upon the occurrence of a Change of Control
(but in no event more than 90 days after the occurrence of such Change of
Control) at a redemption price equal to 100% of the principal amount thereof,
plus the Applicable Premium as of, and accrued but unpaid interest, if any, to,
the date of redemption (subject to the right of Holders of record on the
relevant record date to receive interest due on the relevant interest payment
date).
 
SELECTION AND NOTICE
 
    In the case of any partial redemption, selection of the Notes for redemption
will be made by the Trustee in compliance with the requirements of the principal
national securities exchange, if any, on which the Notes are listed, or, if such
other Notes are not so listed, on a pro rata basis, by lot or by such method as
such Trustee shall deem fair and appropriate; PROVIDED that no Note of $1,000 or
less shall be redeemed in part. Notices of redemption shall be mailed by first
class mail at least 30 but not more than 60 days before the redemption date to
each Holder of the Notes to be redeemed at its registered address. If any Note
is to be redeemed in part only, the notice of redemption that relates to such
Note shall state the portion of the principal amount thereof to be redeemed. A
new Note in principal amount equal to the unredeemed portion thereof will be
issued in the name of the Holder thereof upon cancellation of the original Note.
On and after the redemption date, interest will cease to accrue on the Notes or
portions of them called for redemption unless the Company defaults in payment of
the redemption price.
 
RANKING AND SUBORDINATION
 
    The payment of principal of, premium, if any, and interest on the Notes and
any other payment obligations of the Company in respect of the Notes (including
any obligation to repurchase the Notes) will be subordinated in right of
payment, as set forth in the Indenture, to the prior payment in full in cash of
all Senior Debt, whether outstanding on the date of the Indenture or thereafter
incurred.
 
    Upon any payment or distribution of property or securities to creditors of
the Company in a liquidation or dissolution of the Company or in a bankruptcy,
reorganization, insolvency, receivership or similar proceeding relating to the
Company or its property, or in an assignment for the benefit of creditors or any
marshalling of the Company's assets and liabilities, the holders of Senior Debt
will be entitled to receive payment in full of all Obligations due in respect of
such Senior Debt (including interest after the commencement of any such
proceeding at the rate specified in the applicable Senior Debt, whether or not a
claim for such interest would be allowed in a proceeding) before the Holders of
the Notes will be entitled to receive any payment with respect to the Notes, and
until all Obligations with respect to Senior Debt are
 
                                       67
<PAGE>
paid in full, any distribution to which the Holders of the Notes would be
entitled shall be made to the holders of Senior Debt (except that Holders of the
Notes may receive payments made from the trust described under "--Legal
Defeasance and Covenant Defeasance").
 
    The Company also may not make any payment (whether by redemption, purchase,
retirement, defeasance or otherwise) upon or in respect of the Notes (except
from the trust described under "--Legal Defeasance and Covenant Defeasance") if
(i) a default in the payment of the principal of, premium, if any, or interest
on Designated Senior Debt occurs ("payment default") or (ii) any other default
occurs and is continuing with respect to Designated Senior Debt that permits, or
with the giving of notice or passage of time or both (unless cured or waived)
will permit, holders of the Designated Senior Debt as to which such default
relates to accelerate its maturity ("nonpayment default") and (solely with
respect to this clause (ii)) the Trustee receives a notice of such default (a
"Payment Blockage Notice") from the Company or the holders (or their
representative) of any Designated Senior Debt. Cash payments on the Notes shall
be resumed (a) in the case of a payment default, upon the date on which such
default is cured or waived and (b) in case of a nonpayment default, the earlier
of the date on which such nonpayment default is cured or waived or 179 days
after the date on which the applicable Payment Blockage Notice is received,
unless the maturity of any Designated Senior Debt has been accelerated or a
default of the type described in clause (ix) under the caption "Events of
Default and Remedies" has occurred and is continuing. No new period of payment
blockage may be commenced unless and until 360 days have elapsed since the date
of commencement of the payment blockage period resulting from the immediately
prior Payment Blockage Notice. No nonpayment default in respect of Designated
Senior Debt that existed or was continuing on the date of delivery of any
Payment Blockage Notice to the Trustee shall be, or be made, the basis for a
subsequent Payment Blockage Notice unless such default shall have been cured or
waived for a period of no less than 90 days.
 
    The Indenture further requires that the Company promptly notify holders of
Senior Debt if payment of the Notes is accelerated because of an Event of
Default.
 
    As a result of the subordination provisions described above, in the event of
a liquidation or insolvency of the Company, Holders of the Notes may recover
less ratably than creditors of the Company who are holders of Senior Debt. As of
March 31, 1998, on a pro forma basis, after giving effect to the Worland Field
Acquisition and the related financings and the application of the net proceeds
from the Offering, (i) the principal amount of Senior Debt outstanding would
have been $3.9 million (exclusive of $75 million of unused commitments under the
Credit Facility), (ii) there would have been no Senior Subordinated Debt of the
Company outstanding (exclusive of the Notes) and (iii) the Subsidiary Guarantors
would have had no Indebtedness outstanding other than guarantees of the Credit
Facility and the Subsidiary Guarantees. The Indenture will limit, subject to
certain financial tests, the amount of additional Indebtedness, including Senior
Debt, that the Company and its Subsidiaries can incur. See "--Certain
Covenants-- Incurrence of Indebtedness and Issuance of Disqualified Stock."
 
SUBSIDIARY GUARANTEES
 
    The Company's payment obligations under the Notes will be jointly, severally
and unconditionally guaranteed by each Subsidiary Guarantor and any future
Restricted Subsidiary of the Company. The Subsidiary Guarantees will be
subordinated to Guarantor Senior Debt of the Subsidiary Guarantors to the same
extent and in the same manner as the Notes are subordinated to the Senior Debt.
As of March 31, 1998, on a pro forma basis after giving effect to the Worland
Field Acquisition and the relating financing and the Offering, there would have
been no Guarantor Senior Debt of Subsidiary Guarantors outstanding other than
the Subsidiary Guarantees and guarantees of borrowings under the Credit
Facility. Although the Indenture contains limitations on the amount of
additional Indebtedness that the Company's Restricted Subsidiaries may incur,
under certain circumstances the amount of such Indebtedness could be
 
                                       68
<PAGE>
substantial and, in any case, such Indebtedness may be Guarantor Senior Debt.
See "--Certain Covenants--Incurrence of Indebtedness and Issuance of
Disqualified Stock" and "--Ranking and Subordination".
 
    The obligations of each Subsidiary Guarantor will be limited to the maximum
amount as will, after giving effect to all other contingent and fixed
liabilities of such Subsidiary Guarantor (including, without limitation, any
guarantees in respect of Indebtedness under the Credit Facility) and after
giving effect to any collections from or payments made by or on behalf of any
other Subsidiary Guarantor in respect of the obligations of such other
Subsidiary Guarantor under its Subsidiary Guarantee or pursuant to its
contribution obligations under the Indenture, result in the obligations of such
Subsidiary Guarantor under its Subsidiary Guarantee not constituting a
fraudulent conveyance or fraudulent transfer under federal or state law.
 
    Each Subsidiary Guarantor may consolidate with or merge into or sell its
assets to the Company or another Subsidiary Guarantor without limitation. Each
Subsidiary Guarantor may consolidate with or merge into or sell all or
substantially all its assets to a corporation, partnership or trust other than
the Company or another Subsidiary Guarantor (whether or not affiliated with the
Subsidiary Guarantor). Upon the sale or disposition of a Subsidiary Guarantor
(by merger, consolidation, the sale of its Capital Stock or the sale of all or
substantially all of its assets) to a Person (whether or not an Affiliate of the
Subsidiary Guarantor) which is not a Subsidiary of the Company, which sale or
disposition is otherwise in compliance with the Indenture (including the
covenant described under "--Repurchase at the Option of Holders--Asset Sales"),
such Subsidiary Guarantor will be deemed released from all its obligations under
the Indenture and its Subsidiary Guarantee and such Subsidiary Guarantee will
terminate; PROVIDED, HOWEVER, that any such termination will occur only to the
extent that all obligations in respect of Indebtedness of such Subsidiary
Guarantor under the Credit Facility and all of its guarantees of, and under all
of its pledges of assets or other security interests which secure, any other
Indebtedness of the Company will also terminate upon such release, sale or
transfer.
 
    Any Subsidiary Guarantor that is designated an Unrestricted Subsidiary in
accordance with the terms of the Indenture shall, upon such designation, be
released and relieved of its obligations under its Subsidiary Guarantee and any
Unrestricted Subsidiary whose designation as such is revoked and any newly
formed or newly acquired Subsidiary that becomes a Restricted Subsidiary will be
required to execute a Subsidiary Guarantee in accordance with the terms of the
Indenture.
 
MANDATORY REDEMPTION
 
    Except as set forth below under "--Repurchase at the Option of Holders," the
Company is not required to make mandatory redemption or sinking fund payments
with respect to the Notes.
 
REPURCHASE AT THE OPTION OF HOLDERS
 
    CHANGE OF CONTROL
 
    Upon the occurrence of a Change of Control, each Holder of the Notes will,
unless the Company shall have elected to redeem the Notes prior to August 1,
2003 upon a Change of Control as permitted by the third paragraph of "--Optional
Redemption," have the right to require the Company to repurchase all or any part
(equal to $1,000 or an integral multiple thereof) of such Holder's Notes
pursuant to the offer described below (the "Change of Control Offer") at an
offer price in cash equal to 101% of the aggregate principal amount of the Notes
plus accrued and unpaid interest, if any, thereon to the date of purchase (the
"Change of Control Payment"). Within 30 days following any Change of Control,
the Company will mail a notice to each Holder describing the transaction or
transactions that constitute the Change of Control and offer to repurchase the
Notes pursuant to the procedures required by the Indenture and described in such
notice on a date no earlier than 30 days nor later than 60 days from the date
such notice is mailed (the "Change of Control Payment Date").
 
                                       69
<PAGE>
    On the Change of Control Payment Date, the Company will, to the extent
lawful, (i) accept for payment all Notes or portions thereof properly tendered
pursuant to the Change of Control Offer, (ii) deposit with the Paying Agent an
amount equal to the Change of Control Payment in respect of all the Notes or
portions thereof so tendered and (iii) deliver or cause to be delivered to the
Trustee the relevant Notes so accepted together with an Officers' Certificate
stating the aggregate principal amount of such Notes or portions thereof being
purchased by the Company. The Paying Agent will promptly mail to each Holder of
the Notes so tendered the Change of Control Payment for such Notes, and the
Trustee will promptly authenticate and mail (or cause to be transferred by book
entry) to each tendering Holder a new Note equal in principal amount to any
unpurchased portion of the Notes surrendered, if any; PROVIDED that each such
new Note will be in a principal amount of $1,000 or an integral multiple
thereof. The Indenture will provide that, prior to complying with the provisions
of this covenant, but in any event within 30 days following a Change of Control,
the Company will either repay all outstanding Senior Debt or obtain the
requisite consents, if any, under all agreements governing outstanding Senior
Debt to permit the repurchase of the Notes required by this covenant. The
Company will publicly announce the results of the Change of Control Offer on or
as soon as practicable after the Change of Control Payment Date.
 
    Except as described above with respect to a Change of Control, the Indenture
will not contain provisions that permit the Holders of the Notes to require that
the Company repurchase or redeem the Notes in the event of a takeover,
recapitalization or similar transaction.
 
    The Company will not be required to make a Change of Control Offer if a
third party makes the Change of Control Offer in the manner, at the times and
otherwise in compliance with the requirements set forth in the Indenture
applicable to a Change of Control Offer made by the Company and purchases all
Notes validly tendered and not withdrawn under such Change of Control Offer.
 
    The definition of Change of Control includes a phrase relating to the sale,
lease, transfer, conveyance or other disposition of "all or substantially all"
of the assets of the Company and its Subsidiaries taken as a whole. Although
there is a developing body of case law interpreting the phrase "substantially
all," there is no precise established definition of the phrase under applicable
law. Accordingly, the ability of a Holder of the Notes to require the Company to
repurchase such Notes as a result of a sale, lease, transfer, conveyance or
other disposition of less than all of the assets of the Company and its
Subsidiaries taken as a whole to another Person or group may be uncertain.
 
    In the event that the Company makes an offer to purchase the Notes pursuant
to the provisions of this "--Change of Control" covenant, the Company intends to
comply with any applicable securities laws and regulations, including any
applicable requirements of Section 14(e) of, and Rule 14e-1 under, the
Securities Exchange Act of 1934, as amended (the "Exchange Act").
 
    ASSET SALES
 
    The Indenture provides that the Company will not, and will not permit any of
its Restricted Subsidiaries to, engage in an Asset Sale unless (i) the Company
or the Restricted Subsidiary, as the case may be, receives consideration at the
time of such Asset Sale at least equal to the fair market value (as determined
in good faith by a resolution of the Board of Directors set forth in an
Officers' Certificate delivered to the Trustee, which determination shall be
conclusive evidence of compliance with this provision) of the assets or Equity
Interests issued or sold or otherwise disposed of and (ii) at least 85% of the
consideration therefor received by the Company or such Restricted Subsidiary
from such Asset Sale is in the form of cash, Cash Equivalents, properties and
capital assets to be used by the Company or any Restricted Subsidiary in the Oil
and Gas Business or oil and gas properties owned or held by another Person which
are to be used in the Oil and Gas Business of the Company or its Restricted
Subsidiaries, or any combination thereof (collectively the "Cash
Consideration"); PROVIDED that the amount of (x) any liabilities (as shown on
the Company's or such Restricted Subsidiary's most recent balance sheet) of the
Company or any Restricted Subsidiary (other than contingent liabilities and
liabilities that are by their terms subordinated to the Notes or any guarantee
thereof) that are assumed by the transferee of any such assets pursuant to a
customary novation agreement that releases the Company or such Restricted
 
                                       70
<PAGE>
Subsidiary from further liability and (y) any non-cash consideration received by
the Company or any such Restricted Subsidiary from such transferee that are
converted by the Company or such Restricted Subsidiary into cash within 180 days
of closing such Asset Sale, shall be deemed to be cash for purposes of this
provision (to the extent of the cash received); PROVIDED, HOWEVER, that the
Company and its Restricted Subsidiaries may make Asset Sales with a fair market
value not exceeding $10 million in the aggregate in each fiscal year free from
any of the restrictions, requirements or other provisions under this "--Asset
Sales" section.
 
    Within 360 days after the receipt of any Net Proceeds from an Asset Sale,
the Company may apply such Net Proceeds, at its option, in any order or
combination, (a) to reduce Senior Debt or Guarantor Senior Debt, (b) to make
Permitted Investments, (c) to make investments in interests in other Oil and Gas
Businesses or (d) to make capital expenditures in respect of the Company's or
its Restricted Subsidiaries' Oil and Gas Business or to purchase long-term
assets that are used or useful in the Oil and Gas Business. Pending the final
application of any such Net Proceeds, the Company may temporarily reduce Senior
Debt that is revolving debt or otherwise invest such Net Proceeds in any manner
that is not prohibited by the Indenture. Any Net Proceeds from Asset Sales that
are not applied as provided in the first sentence of this paragraph will (after
the expiration of the periods specified in this paragraph) be deemed to
constitute "Excess Proceeds."
 
    When the aggregate amount of Excess Proceeds exceeds $15 million, the
Company will be required to make an offer to all Holders of the Notes and, to
the extent required by the terms thereof, to all holders or lenders of Pari
Passu Indebtedness (an "Asset Sale Offer") to purchase the maximum principal
amount of the Notes and any such Pari Passu Indebtedness to which the Asset Sale
Offer applies that may be purchased out of the Excess Proceeds, at an offer
price in cash equal to 100% of the principal amount thereof plus accrued and
unpaid interest thereon to the date of purchase, in accordance with the
procedures set forth in the Indenture or the agreements governing the Pari Passu
Indebtedness, as applicable. To the extent that the aggregate principal amount
of the Notes and Pari Passu Indebtedness (or accreted value, as the case may be)
tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the
Company may use any remaining Excess Proceeds for general corporate purposes. If
the aggregate principal amount of the Notes surrendered by Holders thereof and
other Pari Passu Indebtedness surrendered by holders or lenders thereof,
collectively, exceeds the amount of Excess Proceeds, the Trustee shall select
the Notes and Pari Passu Indebtedness to be purchased on a pro rata basis, based
on the aggregate principal amount thereof (or accreted value, as the case may
be) surrendered in such Asset Sale Offer. Upon completion of such Asset Sale
Offer, the amount of Excess Proceeds shall be reset at zero.
 
    In the event that the Company makes an offer to purchase the Notes pursuant
to the provisions of this "--Asset Sales" covenant, the Company intends to
comply with any applicable securities laws and regulations, including any
applicable requirements of Section 14(e) of, and Rule 14e-1 under, the Exchange
Act.
 
    The Credit Facility may prohibit the Company from purchasing any Notes and
also provides that certain change of control events with respect to the Company
would constitute a default thereunder. Any future credit agreements or other
agreements relating to Senior Debt to which the Company becomes a party may
contain similar restrictions and provisions. In the event a Change of Control or
Asset Sale Offer occurs at a time when the Company is prohibited from purchasing
the Notes by the terms of the Credit Facility or other agreements relating to
other Senior Debt, the Company could seek the consent of its lenders to the
purchase or could attempt to refinance the borrowings that contain such
prohibition. If the Company does not obtain such a consent or refinance such
borrowings, the Company may remain prohibited from purchasing the Notes. In such
case, the Company's failure to purchase tendered Notes would constitute an Event
of Default under the Indenture which would, in turn, constitute a default under
the Credit Facility. In such circumstances, the subordination provisions in the
Indenture would likely restrict payments to the Holders of the Notes.

CERTAIN COVENANTS
 
    RESTRICTED PAYMENTS
 
    The Indenture provides that the Company will not, and will not permit any of
its Restricted Subsidiaries to, directly or indirectly: (i) declare or pay any
dividend or make any other payment or distribution on account of the Equity
Interests of the Company or any Restricted Subsidiary (including, without
limitation, any payment in connection with any merger or consolidation involving
the Company) to the direct or indirect holders of Equity Interests of the
Company or any Restricted Subsidiary in their capacity as such (other than
dividends or distributions payable in Equity Interests of the Company or a
Restricted Subsidiary (other than Disqualified Stock) and other than dividends
or distributions payable to the Company or a Restricted Subsidiary so long as,
in the case of any dividend or distribution payable on or in respect of any
class or series of securities issued by a Subsidiary other than a Wholly Owned
Restricted Subsidiary, the Company or a Restricted Subsidiary receives at least
its pro rata share of such dividend or distribution in accordance with its
Equity Interests in such class or series of securities); (ii) purchase, redeem
or otherwise acquire or retire for value any Equity Interests of the Company or
any Subsidiary of the Company that is not a Wholly Owned Restricted Subsidiary
of the Company; (iii) make any principal payment on, or purchase, redeem,
defease or otherwise acquire or retire for value any Indebtedness that is
subordinated to the Notes, except at final maturity or as a mandatory or sinking
fund repayment; or (iv) make any Restricted Investment (all such payments and
other actions set forth in clauses (i) through (iv) above being collectively
referred to as "Restricted Payments"), unless, at the time of and after giving
effect to such Restricted Payment:
 
        (a) no Default or Event of Default shall have occurred and be continuing
    or would occur as a consequence thereof; and
 
        (b) the Company would, at the time of such Restricted Payment and after
    giving pro forma effect thereto as if such Restricted Payment had been made
    at the beginning of the applicable four-quarter period, have been permitted
    to incur at least $1.00 of additional Indebtedness pursuant to the Fixed
    Charge Coverage Ratio test set forth in the first paragraph of the covenant
    described below under the caption "--Incurrence of Indebtedness and Issuance
    of Disqualified Stock"; and
 
        (c) such Restricted Payment, together with the aggregate of all other
    Restricted Payments made by the Company and its Restricted Subsidiaries
    after the date of the Indenture (excluding Restricted Payments permitted by
    clauses (1), (3), (4) and (6) of the next succeeding paragraph), is less
    than the sum of (i) 50% of the Consolidated Net Income of the Company for
    the period (taken as one accounting period) from the beginning of the first
    fiscal quarter commencing after the date of the Indenture to the end of the
    Company's most recently ended fiscal quarter for which internal financial
    statements are available at the time of such Restricted Payment (or, if such
    Consolidated Net Income for such period is a deficit, less 100% of such
    deficit), PLUS (ii) 100% of the aggregate net cash proceeds received by the
    Company from the issue or sale since the date of the Indenture of Equity
    Interests of the Company or of debt securities of the Company that have been
    converted into or exchanged for such Equity Interests (other than Equity
    Interests (or convertible debt securities) sold to a Subsidiary of the
    Company and other than Disqualified Stock or debt securities that have been
    converted into Disqualified Stock), PLUS (iii) to the extent that any
    Restricted Investment that was made after the date of the Indenture is sold
    for cash or otherwise liquidated or repaid for cash or the receipt of
    properties used in the Oil and Gas Business, the lesser of (A) the net cash
    proceeds of such sale, liquidation or repayment or the fair market value of
    property received in exchange therefor and (B) the amount of such Restricted
    Investment, PROVIDED, however, that the foregoing provisions of this
    paragraph (c) will not prohibit Restricted Payments in an aggregate amount
    not to exceed $15 million.
 
    The foregoing provisions will not prohibit (1) the payment of any dividend
within 60 days after the date of declaration thereof, if at said date of
declaration such payment would have complied with the provisions of the
Indenture; (2) the redemption, repurchase, retirement or other acquisition of
any Equity
 
                                       72
<PAGE>
Interests of the Company in exchange for, or out of the proceeds of, the
substantially concurrent sale (other than to a Subsidiary of the Company) of
other Equity Interests of the Company (other than a sale of Disqualified Stock);
PROVIDED that the amount of any such net cash proceeds that are utilized for any
such redemption, repurchase, retirement or other acquisition shall be excluded
from clause (c)(ii) of the preceding paragraph; (3) the defeasance, redemption
or repurchase of subordinated Indebtedness with the net cash proceeds from an
incurrence of subordinated Permitted Refinancing Debt or the substantially
concurrent sale (other than to a Subsidiary of the Company) of Equity Interests
(other than Disqualified Stock) of the Company; PROVIDED that the amount of any
such net cash proceeds that are utilized for any such redemption, repurchase,
retirement or other acquisition shall be excluded from clause (c)(ii) of the
preceding paragraph; (4) the repurchase, redemption or other acquisition or
retirement for value of any Equity Interests of the Company or any Subsidiary of
the Company held by any of the Company's (or any of its Subsidiaries') employees
pursuant to any management equity subscription agreement or stock option
agreement in effect as of the date of the Indenture; PROVIDED that the aggregate
price paid for all such repurchased, redeemed, acquired or retired Equity
Interests shall not exceed $2 million in any twelve-month period; and PROVIDED
FURTHER that no Default or Event of Default shall have occurred and be
continuing immediately after such transaction; (5) repurchases of Equity
Interests deemed to occur upon exercise of stock options if such Equity
Interests represent a portion of the exercise price of such options; (6) the
making of loans by the Company or any of its Restricted Subsidiaries to officers
or directors of the Company; PROVIDED that the aggregate outstanding amount of
such loans shall not exceed, at any time, $2 million plus any such loans
outstanding on the date of the Indenture; and (7) during the period the Company
is subject to Subchapter S of the Internal Revenue Code of 1986, as amended (the
"Code"), and after such period to the extent relating to the liability for such
period, the making of payments or distributions or the payment of dividends in
amounts equal to the amounts required for the Company's stockholders to pay
Federal, state and local income taxes to the extent such income taxes are
attributable to the taxable income of the Company.
 
    The amount of all Restricted Payments (other than cash) shall be the fair
market value (as determined in good faith by a resolution of the Board of
Directors set forth in an Officers' Certificate delivered to the Trustee) on the
date of the Restricted Payment of the asset(s) proposed to be transferred by the
Company or the applicable Restricted Subsidiary, as the case may be, pursuant to
the Restricted Payment. In computing Consolidated Net Income of the Company
under paragraph (c) above, (1) the Company shall use audited financial
statements for the portions of the relevant period for which audited financial
statements are available on the date of determination and unaudited financial
statements and other current financial data based on the books and records of
the Company for the remaining portion of such period and (2) the Company shall
be permitted to rely in good faith on the financial statements and other
financial data derived from the books and records of the Company that are
available on the date of determination.
 
    DESIGNATION OF UNRESTRICTED SUBSIDIARIES
 
    The Board of Directors of the Company may designate any Restricted
Subsidiary to be an Unrestricted Subsidiary if such designation would not cause
a Default. For purposes of making such determination, all outstanding
Investments by the Company and its Restricted Subsidiaries (except to the extent
repaid in cash) in the Subsidiary so designated will be deemed to be Restricted
Payments at the time of such designation and will reduce the amount available
for Restricted Payments under clause (c) of the first paragraph of the covenant
"Restricted Payments." All such outstanding Investments will be deemed to
constitute Investments in an amount equal to the greater of the fair market
value or the book value of such Investments at the time of such designation.
Such designation will only be permitted if such Restricted Payment would be
permitted at such time and if such Restricted Subsidiary otherwise meets the
definition of an Unrestricted Subsidiary.

<PAGE>
    INCURRENCE OF INDEBTEDNESS AND ISSUANCE OF DISQUALIFIED STOCK
 
    The Indenture provides that the Company will not, and will not permit any of
its Restricted Subsidiaries to, directly or indirectly, create, incur, issue,
assume, guarantee or otherwise become directly or indirectly liable,
contingently or otherwise, with respect to (collectively, "incur") any
Indebtedness or issue any Disqualified Stock and the Company will not permit any
of its Restricted Subsidiaries to issue any shares of Disqualified Stock to any
Person other than the Company or a Wholly-Owned Restricted Subsidiary of the
Company; PROVIDED, HOWEVER, that the Company and any Subsidiary Guarantor may
incur Indebtedness or issue shares of Disqualified Stock if:
 
        (i) the Fixed Charge Coverage Ratio for the Company's most recently
    ended four full fiscal quarters for which internal financial statements are
    available immediately preceding the date on which such additional
    Indebtedness is incurred or such Disqualified Stock is issued would have
    been at least 2.5 to 1, determined on a pro forma basis as set forth in the
    definition of Fixed Charge Coverage Ratio; and
 
        (ii) no Default or Event of Default shall have occurred and be
    continuing at the time such additional Indebtedness is incurred or such
    Disqualified Stock is issued or would occur as a consequence of the
    incurrence of the additional Indebtedness or the issuance of the
    Disqualified Stock.
 
    Notwithstanding the foregoing, the Indenture does not prohibit any of the
following (collectively, "Permitted Indebtedness"): (a) the Indebtedness
evidenced by the Notes; (b) the incurrence by the Company or any of its
Restricted Subsidiaries of Indebtedness pursuant to Credit Facilities, so long
as the aggregate principal amount of all Indebtedness outstanding under all
Credit Facilities does not, at any one time, exceed the greater of (i) $175
million and (ii) the Borrowing Base, provided that the Company may incur more
than $175 million of Indebtedness pursuant to Credit Facilities only if the
Fixed Charge Coverage Ratio for the Company's most recently ended four full
fiscal quarters for which internal financial statements are available would have
been at least 2.0 to 1, determined on a pro forma basis as set forth in the
definition of Fixed Charge Coverage Ratio; (c) the guarantee by any Subsidiary
Guarantor of any Indebtedness that is permitted by the Indenture to be incurred
by the Company; (d) all Indebtedness of the Company and its Restricted
Subsidiaries in existence as of the date of the Indenture; (e) intercompany
Indebtedness between or among the Company and any of its Wholly Owned Restricted

Indebtedness, (A) any subsequent issuance or transfer of Equity Interests that
results in any such Indebtedness being held by a Person other than the Company
or a Wholly Owned Restricted Subsidiary and (B) any sale or other transfer of
any such Indebtedness to a Person that is not either the Company or a Wholly
Owned Restricted Subsidiary shall be deemed, in each case, to constitute an
incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as
the case may be; (f) Indebtedness in connection with one or more standby letters
of credit, guarantees, performance bonds or other reimbursement obligations, in
each case, issued in the ordinary course of business and not in connection with
the borrowing of money or the obtaining of advances or credit (other than
advances or credit on open account, includible in current liabilities, for goods
and services in the ordinary course of business and on terms and conditions
which are customary in the Oil and Gas Business, and other than the extension of
credit represented by such letter of credit, guarantee or performance bond
itself), not to exceed in the aggregate at any given time 5% of Total Assets;
(g) Indebtedness under Interest Rate Hedging Agreements entered into for the
purpose of limiting interest rate risks, PROVIDED that the obligations under
such agreements are related to payment obligations on Indebtedness otherwise
permitted by the terms of this covenant and that the aggregate notional
principal amount of such agreements does not exceed 105% of the principal amount
of the Indebtedness to which such agreements relate; (h) Indebtedness under Oil
and Gas Hedging Contracts, PROVIDED that such contracts were entered into in the
ordinary course of business for the purpose of limiting risks that arise in the
ordinary course of business of the Company and its Restricted Subsidiaries; (i)
the incurrence by the Company and its Restricted Subsidiaries of Indebtedness
not otherwise permitted to be incurred pursuant
 
                                       74
<PAGE>
to this paragraph, PROVIDED that the aggregate principal amount of all
Indebtedness incurred pursuant to this clause (i), together with all Permitted
Refinancing Debt incurred pursuant to clause (j) of this paragraph in respect of
Indebtedness previously incurred pursuant to this clause (i), does not exceed
$20 million at any one time outstanding; (j) Permitted Refinancing Debt incurred
in exchange for, or the net proceeds of which are used to refinance, extend,
renew, replace, defease or refund, Indebtedness that was permitted by the
Indenture to be incurred (including Indebtedness previously incurred pursuant to
this clause (j), but excluding Indebtedness under clauses (b), (e), (f), (g),
(h), (k), (l) and (m)); (k) accounts payable or other obligations of the Company
or any Restricted Subsidiary to trade creditors created or assumed by the
Company or such Restricted Subsidiary in the ordinary course of business in
connection with the obtaining of goods or services; (l) Indebtedness consisting
of obligations in respect of purchase price adjustments, guarantees or
indemnities in connection with the acquisition or disposition of assets; (m)

at any one time outstanding, exceed 2% of the Total Assets of the Company; (n)
rents and royalties due others incurred in the ordinary course of the Oil and
Gas Business; and (o) Indebtedness of a Subsidiary Guarantor in respect of the
Subsidiary Guarantee of such Subsidiary Guarantor.
 
    The Indenture provides that the Company will not permit any Unrestricted
Subsidiary to incur any Indebtedness other than Non-Recourse Debt; PROVIDED,
HOWEVER, if any such Indebtedness ceases to be Non-Recourse Debt, such event
shall be deemed to constitute an incurrence of Indebtedness by the Company.
 
    NO LAYERING
 
    The Indenture provides that (i) the Company will not incur, create, issue,
assume, guarantee or otherwise become liable for any Indebtedness that is
subordinate or junior in right of payment to any Senior Debt and senior in any
respect in right of payment to the Notes and (ii) the Subsidiary Guarantors will
not directly or indirectly incur, create, issue, assume, guarantee or otherwise
become liable for any Indebtedness that is subordinate or junior in right of
payment to Guarantor Senior Debt and senior in any respect in right of payment
to the Subsidiary Guarantees, PROVIDED, HOWEVER, that the foregoing limitations
will not apply to distinctions between categories of Indebtedness that exist by
reason of any Liens arising or created in accordance with the provisions of the
Indenture in respect of some but not all such Indebtedness.
 
    LIENS
 
    The Indenture provides that the Company will not, and will not permit any of
its Restricted Subsidiaries to, create, incur, assume or otherwise cause or
suffer to exist or become effective any Lien securing Indebtedness of any kind
(other than Permitted Liens) upon any of its property or assets, now owned or
hereafter acquired, unless all payments under the Notes are secured by such Lien
prior to, or on an equal and ratable basis with, the Indebtedness so secured for
so long as such Indebtedness is secured by such Lien.
 
    SALE AND LEASEBACK TRANSACTIONS
 
    The Indenture provides that the Company will not, and will not permit any of
its Restricted Subsidiaries to, enter into any sale and leaseback transaction;
PROVIDED that the Company or its Restricted Subsidiaries may enter into a sale
and leaseback transaction if (i) the Company could have incurred Indebtedness in
an amount equal to the Attributable Debt relating to such sale and leaseback
transaction pursuant to the test set forth in the first paragraph of the
covenant described above under the caption "Incurrence of Indebtedness and
Issuance of Disqualified Stock" or (ii) the gross cash proceeds of such sale and
leaseback transaction are at least equal to the fair market value (as determined

Certificate delivered to the Trustee) of the property that is the subject of
such sale and leaseback transaction and the transfer of assets in such sale
 
                                       75
<PAGE>
and leaseback transaction is permitted by, and the Company applies the net
proceeds of such transaction in compliance with, the covenant described above
under the caption "Repurchase at the Option of Holders-- Asset Sales."
 
   DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING RESTRICTED SUBSIDIARIES
 
    The Indenture provides that the Company will not, and will not permit any of
its Restricted Subsidiaries to, directly or indirectly, create or otherwise
cause or suffer to exist or become effective any encumbrance or restriction on
the ability of any Restricted Subsidiary to (i)(x) pay dividends or make any
other distributions to the Company or any of the Restricted Subsidiaries of the
Company (1) on its Capital Stock or (2) with respect to any other interest or
participation in, or measured by, its profits, or (y) pay any Indebtedness owed
to the Company or any Restricted Subsidiaries of the Company, (ii) make loans or
advances to the Company or any Restricted Subsidiaries of the Company or (iii)
transfer any of its properties or assets to the Company or any Restricted

existing under or by reason of (a) the Credit Facility as in effect as of the
date of the Indenture and any amendments, modifications, restatements, renewals,
increases, supplements, refundings, replacements or refinancings thereof or any
other Credit Facility, PROVIDED that such amendments, modifications,
restatements, renewals, increases, supplements, refundings, replacements,
refinancings or other Credit Facilities are no more restrictive with respect to
such dividend and other payment restrictions than those contained in the Credit
Facility as in effect on the date of the Indenture, (b) the Indenture and the
Notes, (c) applicable law, (d) any instrument governing Indebtedness or Capital
Stock of a Person acquired by the Company or any of its Restricted Subsidiaries
as in effect at the time of such acquisition (except, in the case of
Indebtedness, to the extent such Indebtedness was incurred in connection with or
in contemplation of such acquisition), which encumbrance or restriction is not
applicable to any Person, or the properties or assets of any Person, other than
the Person and its Subsidiaries, or the property or assets of the Person and its
Subsidiaries, so acquired, PROVIDED that, such Indebtedness or Capital Stock was
permitted by the terms of the Indenture to be incurred, (e) customary
non-assignment provisions in leases entered into in the ordinary course of
business, (f) purchase money obligations for property acquired in the ordinary
course of business that impose restrictions of the nature described in clause
(iii) above on the property so acquired, (g) Permitted Refinancing Debt,

agreements governing the Indebtedness being refinanced, (h) any other security
agreement, instrument or document relating to Senior Debt hereafter in effect,
provided that such encumbrances or restrictions are customary in connection with
such documents and that the terms and conditions of such encumbrances or

imposed in connection with the Credit Facility, (i) Permitted Liens, (j)
customary provisions in joint venture agreements and other similar agreements
relating to the distribution of revenues from such joint venture or other
business venture, or (k) any agreement relating to a sale and leaseback

encumbrances are customary with respect to a sale and leaseback transaction or
capital lease.
 
   LIMITATION ON THE SALE OR ISSUANCE OF CAPITAL STOCK OF RESTRICTED
   SUBSIDIARIES
 
    The Indenture provides that the Company will not sell or otherwise dispose
of any shares of Capital Stock of a Restricted Subsidiary, and shall not permit
any Restricted Subsidiary, directly or indirectly, to issue or sell or otherwise
dispose of any shares of its Capital Stock except (i) to the Company or a Wholly
Owned Restricted Subsidiary, (ii) if, immediately after giving effect to such
issuance, sale or other disposition, such Restricted Subsidiary remains a
Restricted Subsidiary, (iii) shares of nonvoting Capital Stock of Restricted
Subsidiaries may be issued or sold to employees or directors of the Company or
any Subsidiary, or (iv) if all shares of Capital Stock of such Restricted
Subsidiary are sold or otherwise disposed. In connection with any sale or
disposition of Capital Stock of a Restricted Subsidiary, the
 
                                       76
<PAGE>
Company will be required to comply with the covenant described under the caption
"Repurchase at the Option of Holders--Asset Sales" above.
 
    MERGER, CONSOLIDATION, OR SALE OF ASSETS
 
    The Indenture provides that the Company may not consolidate or merge with or
into (whether or not the Company is the surviving corporation), or sell, assign,
transfer, lease, convey or otherwise dispose of all or substantially all of its
properties or assets, in one or more related transactions, to another Person,
and the Company may not permit any of its Restricted Subsidiaries to enter into
any such transaction or series of transactions if such transaction or series of
transactions would, in the aggregate, result in a sale, assignment, transfer,
lease, conveyance, or other disposition of all or substantially all of the
properties or assets of the Company to another Person unless (i) the Company is
the surviving corporation or the Person formed by or surviving any such
consolidation or merger (if other than the Company) or to which such sale,
assignment, transfer, lease, conveyance or other disposition shall have been
made (the "Surviving Entity") is a corporation organized or existing under the
laws of the United States, any state thereof or the District of Columbia; (ii)
the Surviving Entity (if the Company is not the continuing obligor under the
Indenture) assumes all the obligations of the Company under the Notes and the
Indenture pursuant to a supplemental indenture in a form reasonably satisfactory
to the Trustee; (iii) immediately before and after giving effect to such
transaction or series of transactions no Default or Event of Default exists;
(iv) immediately after giving effect to such transaction or series of
transactions on a pro forma basis (and treating any Indebtedness not previously
an obligation of the Company and its Restricted Subsidiaries which becomes the
obligation of the Company or any of its Restricted Subsidiaries as a result of
such transaction as having been incurred at the time of such transaction or
series of transactions), the Consolidated Net Worth of the Company or the
Surviving Entity (if the Company is not the continuing obligor under the
Indenture) is equal to or greater than the Consolidated Net Worth of the Company
immediately prior to such transaction or series of transactions; and (v) the
Company or the Surviving Entity (if the Company is not the continuing obligor
under the Indenture) will, at the time of such transaction or series of
transactions and after giving pro forma effect thereto as if such transaction or
series of transactions had occurred at the beginning of the applicable
four-quarter period, be permitted to incur at least $1.00 of additional
Indebtedness pursuant to the test set forth in the first paragraph of the
covenant described above under the caption "--Incurrence of Indebtedness and
Issuance of Disqualified Stock." Each Subsidiary Guarantor, if any, unless it is
the other party to the transactions described above, shall have confirmed by
supplemental indenture that its Subsidiary Guarantee shall apply to such
Person's obligations under the Indenture and the Notes. Notwithstanding the
restrictions described in the foregoing clauses (iv) and (v), any Restricted
Subsidiary may consolidate with, merge into or transfer all or part of its
properties and assets to the Company, and any Wholly Owned Restricted Subsidiary
may consolidate with, merge into or transfer all or part of its properties and
assets to another Wholly Owned Restricted Subsidiary.
 
    TRANSACTIONS WITH AFFILIATES
 
    The Indenture provides that the Company will not, and will not permit any of
its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or
otherwise dispose of any of its properties or assets to, or purchase any
property or assets from, or enter into or make or amend any contract, agreement,
understanding, loan, advance or guarantee with, or for the benefit of, any of
its Affiliates (each of the foregoing, an "Affiliate Transaction"), unless (i)
such Affiliate Transaction is on terms that are no less favorable to the Company
or the relevant Restricted Subsidiary than those that would have been obtained
in a comparable transaction by the Company or such Restricted Subsidiary with an
unrelated Person and (ii) the Company delivers to the Trustee (a) with respect
to any Affiliate Transaction or series of related Affiliate Transactions
involving aggregate consideration in excess of $1 million but less than or equal
to $5 million, an Officer's Certificate certifying that such Affiliate
Transaction complies with clause (i) above, (b) with respect to any Affiliate
Transaction or series of related Affiliate Transactions involving
 
                                       77
<PAGE>
aggregate consideration in excess of $5 million but less than or equal to $10
million, a resolution of the Board of Directors set forth in an Officer's
Certificate certifying that such Affiliate Transaction complies with clause (i)
above and that such Affiliate Transaction has been approved in good faith by a
majority of the members of the Board of Directors who have no financial interest
in such Affiliate Transaction, which resolution shall be conclusive evidence of
compliance with this provision, and (c) with respect to any Affiliate
Transaction or series of related Affiliate Transactions involving aggregate
consideration in excess of $10 million, an Officer's Certificate as described in
clause (b) above and an opinion as to the fairness to the Company or such
Subsidiary of such Affiliate Transaction from a financial point of view issued
by an accounting, appraisal, engineering or investment banking firm of national
standing (for purposes of this clause (c) such opinion and the resolution
described in clause (b) above shall be conclusive evidence of compliance with
this provision); PROVIDED that the following shall not be deemed Affiliate
Transactions: (1) reasonable fees and compensation paid to (including issuances
and grants of securities and stock options), and employment agreements and stock
option and ownership plans for the benefit of, officers, directors, employees or
consultants of the Company or any Restricted Subsidiary of the Company as
determined in good faith by the Company's Board of Directors or senior
management, (2) transactions contemplated by any employment agreement or other

Subsidiaries in the ordinary course of business and consistent with past
practice of the Company or such Subsidiary, (3) transactions between or among

leasehold acquisition, drilling, well servicing and leasehold operations

Restricted Subsidiary than those that would have been obtained in a comparable
transaction by the Company or such Restricted Subsidiary with an unrelated
Person.
 
    ADDITIONAL SUBSIDIARY GUARANTEES
 
    The Indenture provides that if the Company or any of its Restricted
Subsidiaries shall acquire or create another Restricted Subsidiary after the
date of the Indenture, then such newly acquired or created Restricted Subsidiary
will be required to execute a Subsidiary Guarantee in accordance with the terms
of the Indenture.
 
    BUSINESS ACTIVITIES
 
    The Company will not, and will not permit any Restricted Subsidiary to,
engage in any material respect in any business other than the Oil and Gas
Business.
 
    COMMISSION REPORTS
 
    Notwithstanding that the Company is not subject to the reporting
requirements of Section 13 or 15(d) of the Exchange Act, the Company will file
with the Commission and, within 15 days after such filing, provide the Trustee
and Holders with the annual reports and the information, documents and other
reports which are specified in Sections 13 and 15(d) of the Exchange Act. In the
event that the Company is not permitted to file such reports, documents and
information with the Commission, the Company will provide substantially similar
information to the Trustee and the Holders as if the Company were subject to the
reporting requirements of Section 13 or 15(d) of the Exchange Act within 15 days
of the date the Company would have been obligated to file such reports with the
Commission, were the Company permitted to file such reports with the Commission.
The Company also will comply with the other provisions of Section 314(a) of the
Trust Indenture Act.
 
                                       78
<PAGE>
EVENTS OF DEFAULT AND REMEDIES
 
    The Indenture provides that each of the following constitutes an Event of
Default: (i) a default for 30 consecutive days in the payment when due of
interest on the Notes (whether or not prohibited by the subordination provisions
of the Indenture); (ii) a default in payment when due of the principal of or
premium, if any, on the Notes (whether or not prohibited by the subordination
provisions of the Indenture); (iii) the failure by the Company or a Subsidiary
Guarantor to comply with its obligations under "Certain Covenants--Merger,
Consolidation or Sale of Assets" above; (iv) the failure by the Company for 30
days after notice from the Trustee or the Holders of at least 25% in aggregate
principal amount of the Notes then outstanding to comply with the provisions
described under the captions "Repurchase at the Option of Holders" and "Certain
Covenants" other than the provisions described under "--Merger, Consolidation or
Sale of Assets"; (v) failure by the Company for 60 consecutive days after notice
from the Trustee or the Holders of at least 25% in aggregate principal amount of
the Notes then outstanding to comply with any of its other agreements in the
Indenture or the Notes; (vi) except as permitted by the Indenture, any
Subsidiary Guarantee shall be held in any judicial proceeding to be
unenforceable or invalid or shall cease for any reason to be in full force and
effect or a Subsidiary Guarantor, or any Person acting on behalf of such
Subsidiary Guarantor, shall deny or disaffirm its obligations under its
Subsidiary Guarantee; (vii) a default under any mortgage, indenture or
instrument under which there may be issued or by which there may be secured or
evidenced any Indebtedness for money borrowed by the Company or any of its
Restricted Subsidiaries (or the payment of which is guaranteed by the Company or
any of its Restricted Subsidiaries) whether such Indebtedness or guarantee now
exists, or is created after the date of the Indenture, which default (a) is
caused by a failure to pay principal of such Indebtedness prior to the
expiration of the grace period provided in such Indebtedness on the date of such
default (a "Payment Default") or (b) results in the acceleration of such
Indebtedness prior to its express maturity and, in each case, the principal
amount of any such Indebtedness, together with the principal amount of any other
such Indebtedness under which there is then existing a Payment Default or the
maturity of which has been so accelerated, aggregates $10 million or more;
(viii) the failure by the Company or any of its Restricted Subsidiaries to pay
final, non-appealable judgments aggregating in excess of $10 million, which
judgments remain unpaid or discharged for a period of 60 days; and (ix) certain
events of bankruptcy or insolvency with respect to the Company or any of its
Restricted Subsidiaries.
 
    If any Event of Default occurs and is continuing, the Trustee or the Holders
of at least 25% in aggregate principal amount of the Notes then outstanding may
declare the principal of and accrued but unpaid interest on such Notes to be due
and payable immediately. Notwithstanding the foregoing, in the case of an Event
of Default arising from certain events of bankruptcy or insolvency, with respect
to the Company or any Restricted Subsidiary, all outstanding Notes will become
due and payable without further action or notice. Holders of the Notes may not
enforce the Indenture or the Notes except as provided in the Indenture. Subject
to certain limitations, Holders of a majority in principal amount of the Notes
then outstanding may direct the Trustee in its exercise of any trust or power.
The Trustee may withhold from Holders of the Notes notice of any continuing
Default or Event of Default (except a Default or Event of Default relating to
the payment of principal or interest) if it determines that withholding notice
is in their interest.
 
    The Holders of a majority in aggregate principal amount of the Notes then
outstanding by notice to the Trustee may on behalf of the Holders of all of the
Notes waive any existing Default or Event of Default and its consequences under
the Indenture except a continuing Default or Event of Default in the payment of
interest or premium on, or the principal of, the Notes.
 
    The Company is required to deliver to the Trustee annually a statement
regarding compliance with the Indenture, and the Company is required, within
five business days of becoming aware of any Default or Event of Default, to
deliver to the Trustee a statement specifying such Default or Event of Default.

<PAGE>
LEGAL DEFEASANCE AND COVENANT DEFEASANCE
 
    The Company may, at its option and at any time, elect to have all of its
obligations discharged with respect to the outstanding Notes and have each
Subsidiary Guarantor's, if any, obligation discharged with respect to its
Subsidiary Guarantee ("Legal Defeasance") except for (i) the rights of Holders
of such outstanding Notes to receive payments in respect of the principal of,
premium, if any, or interest on such Notes when such payments are due from the
trust referred to below, (ii) the Company's obligations with respect to such
Notes concerning issuing temporary Notes, registration of such Notes, mutilated,
destroyed, lost or stolen Notes and the maintenance of an office or agency for
payments, (iii) the rights, powers, trusts, duties and immunities of the
Trustee, and the Company's obligations in connection therewith and (iv) the
Legal Defeasance provisions of the Indenture. In addition, the Company may, at
its option and at any time, elect to have the obligations of the Company
released with respect to certain covenants that are described in the Indenture
("Covenant Defeasance") and thereafter any omission to comply with such
obligations shall not constitute a Default or Event of Default. In the event
Covenant Defeasance occurs, certain events (not including non-payment,
bankruptcy, receivership, rehabilitation and insolvency events) described under
"Events of Default and Remedies" will no longer constitute an Event of Default.
 
    In order to exercise either Legal Defeasance or Covenant Defeasance, (i) the
Company must irrevocably deposit with the Trustee, in trust, for the benefit of
the Holders of the Notes, cash in U.S. dollars, non-callable Government
Securities, or a combination thereof, in such amounts as will be sufficient, in
the opinion of a nationally recognized firm of independent public accountants,
to pay the principal of, premium, if any, and interest on the outstanding Notes
on the stated maturity or on the applicable redemption date, as the case may be,
and the Company must specify whether the Notes are being defeased to maturity or
to a particular redemption date; (ii) in the case of Legal Defeasance, the
Company shall have delivered to the Trustee an opinion of counsel in the United
States reasonably acceptable to such Trustee confirming that (A) the Company has
received from, or there has been published by, the Internal Revenue Service a
ruling or (B) since the date of the Indenture, there has been a change in the
applicable federal income tax law, in either case to the effect that, and based
thereon such opinion of counsel shall confirm that, the Holders of the
outstanding Notes will not recognize income, gain or loss for federal income tax
purposes as a result of such Legal Defeasance and will be subject to federal
income tax on the same amounts, in the same manner and at the same times as
would have been the case if such Legal Defeasance had not occurred; (iii) in the
case of Covenant Defeasance, the Company shall have delivered to the Trustee an
opinion of counsel in the United States reasonably acceptable to such Trustee
confirming that the Holders of the outstanding Notes will not recognize income,
gain or loss for federal income tax purposes as a result of such Covenant
Defeasance and will be subject to federal income tax on the same amounts, in the
same manner and at the same times as would have been the case if such Covenant
Defeasance had not occurred; (iv) no Default or Event of Default shall have
occurred and be continuing on the date of such deposit (other than a Default or
Event of Default resulting from the borrowing of funds to be applied to such
deposit) or insofar as Events of Default from bankruptcy or insolvency events
are concerned, at any time in the period ending on the 91st day after the date
of deposit; (v) such Legal Defeasance or Covenant Defeasance will not result in
a breach or violation of, or constitute a default under, any material agreement
or instrument (other than the Indenture) to which the Company or any of its
Subsidiaries is a party or by which the Company or any of its Subsidiaries is
bound; (vi) the Company must have delivered to the Trustee an opinion of counsel
to the effect that after the 91st day following the deposit, the trust funds
will not be subject to the effect of any applicable bankruptcy, insolvency,
reorganization or similar laws affecting creditors' rights generally; (vii) the
Company must deliver to the Trustee an Officers' Certificate stating that the
deposit was not made by the Company with the intent of preferring the Holders of
the Notes over the other creditors of the Company, or with the intent of
defeating, hindering, delaying or defrauding creditors of the Company or others;
and (viii) the Company must deliver to the Trustee an Officers' Certificate and
an opinion of counsel, each stating that
 
                                       80
<PAGE>
all conditions precedent provided for relating to the Legal Defeasance or the
Covenant Defeasance have been complied with.
 
TRANSFER AND EXCHANGE
 
    A Holder may, subject to certain restrictions, transfer or exchange Notes in
accordance with the Indenture. The Registrar and the Trustee may require a
Holder, among other things, to furnish appropriate endorsements and transfer
documents and the Company may require a Holder to pay any taxes and fees
required by law or permitted by the Indenture. The Company is not required to
transfer or exchange any Note selected for redemption. Also, the Company is not
required to transfer or exchange any Note for a period of 15 days before a
selection of the Notes to be redeemed.
 
    The registered Holder of a Note will be treated as the owner of it for all
purposes.
 
AMENDMENT, SUPPLEMENT AND WAIVER
 
    Except as provided in the next two succeeding paragraphs, the Indenture, the
Notes or the Subsidiary Guarantees may be amended or supplemented with the
consent of the Holders of at least a majority in principal amount of the Notes
then outstanding (including, without limitation, consents obtained in connection
with a purchase of, or tender offer or exchange offer for, the Notes), and any
existing default or compliance with any provision of the Indenture or the Notes
or the Subsidiary Guarantees may be waived with the consent of the Holders of a
majority in principal amount of the then outstanding Notes (including consents
obtained in connection with a tender offer or exchange offer for the Notes).
 
    Without the consent of each Holder affected, an amendment or waiver may not
(with respect to any Notes held by a non-consenting Holder): (i) reduce the
principal amount of the Notes whose Holders must consent to an amendment,

change in a Subsidiary Guaranty, if any, that would adversely affect the
Holders. In addition, any amendment to the provisions of Article 10 of the
Indenture (which relates to subordination) will require the consent of the
Holders of at least 66 2/3% in principal amount of the Notes then outstanding if
such amendment would adversely affect the rights of Holders of such Notes.
However, no amendment may be made to the subordination provisions of the

representative thereof authorized to give a consent) consents to such change.
 
    Notwithstanding the foregoing, without the consent of any Holder of the
Notes the Company and the Trustee may amend or supplement the Indenture or the
Notes to cure any ambiguity, defect or inconsistency, to provide for
uncertificated Notes in addition to or in place of certificated Notes (provided,
however, that the uncertificated Notes are issued in registered form for
purposes of section 163(f) of the Code, or in a manner such that the
uncertificated Notes are described in Section 163(f)(2)(B) of the Code), to
provide for the assumption of the Company's obligations to Holders of the Notes
in the case of a merger or consolidation, to make any change that would provide
any additional rights or benefits to the
 
                                       81
<PAGE>
Holders of the Notes or that does not adversely affect the legal rights under
the Indenture of any such Holder, to add Guarantees with respect to the Notes or
to secure the Notes, or to comply with requirements of the Commission in order
to effect or maintain the qualification of the Indenture under the Trust
Indenture Act.
 
CONCERNING THE TRUSTEE
 
    The Indenture contains certain limitations on the rights of the Trustee,
should it become a creditor of the Company, to obtain payment of claims in
certain cases, or to realize on certain property received in respect of any such
claim as security or otherwise. The Trustee will be permitted to engage in other
transactions; however, if it acquires any conflicting interest, it must
eliminate such conflict within 90 days, apply to the Commission for permission
to continue or resign.
 
    The Holders of a majority in principal amount of the then outstanding Notes
will have the right to direct the time, method and place of conducting any
proceeding for exercising any remedy available to the Trustee, subject to
certain exceptions. The Indenture provides that in case an Event of Default
shall occur (which shall not be cured), the Trustee will be required, in the
exercise of its power, to use the degree of care of a prudent man in the conduct
of his own affairs. Subject to such provisions, the Trustee will be under no
obligation to exercise any of its rights or powers under the Indenture at the
request of any Holder of the Notes, unless such Holder shall have offered to
such Trustee security and indemnity satisfactory to it against any loss,
liability or expense.

    "WEIGHTED AVERAGE LIFE TO MATURITY" means, when applied to any Indebtedness
at any date, the number of years obtained by dividing (i) the sum of the
products obtained by multiplying (a) the amount of each then remaining
installment, sinking fund, serial maturity or other required payments of
principal, including payment at final maturity, in respect thereof, by (b) the
number of years (calculated to the nearest one-twelfth) that will elapse between
such date and the making of such payment, by (ii) the then outstanding principal
amount of such Indebtedness.
 
    "WHOLLY OWNED RESTRICTED SUBSIDIARY" of any Person means a Restricted
Subsidiary of such Person all of the outstanding Capital Stock or other
ownership interests of which (other than directors' qualifying shares) shall at
the time be owned, directly or indirectly, by such Person or by one or more
Wholly Owned Restricted Subsidiaries of such Person.

BOOK-ENTRY; DELIVERY AND FORM
 
    The certificates representing the New Notes will initially be represented by
one or more permanent global Notes in definitive, fully registered form without
interest coupons (each a "Restricted Global Note"; and together with the
Regulation S Global Note, the "Global Notes") and will be deposited with the
Trustee as custodian for, and registered in the name of a nominee of, DTC. Old
Notes sold in offshore transactions in reliance on Regulation S under the
Securities Act were initially represented by one or more temporary global Notes
in definitive, fully registered form without interest coupons (each a "Temporary
Regulation S Global Note") and were deposited with the Trustee as custodian for,
and registered in the name of a nominee of, DTC for the accounts of Euroclear
and Cedel Bank. The Temporary Regulation S Global Note is exchangeable for one
or more permanent global Notes (each a "Permanent Regulation S Global Note"; and
together with the Temporary Regulation S Global Notes, the "Regulation S Global
Note") on or after the 40th day following July 24, 1998 upon certification that
the beneficial interests in such global Note are owned by non-U.S. persons.
Prior to the 40th day after the Closing Date, beneficial interests in the
Temporary Regulation S Global Note may only be held through Euroclear or Cedel
Bank.
 
    Ownership of beneficial interests in a Global Note are limited to persons
who have accounts with DTC ("participants") or persons who hold interests
through participants. Ownership of beneficial interests in a Global Note will be
shown on, and the transfer of that ownership will be effected only through,
records maintained by DTC or its nominee (with respect to interests of
participants) and the records of participants (with respect to interests of
persons other than participants). Qualified institutional buyers may hold their
interests in a Restricted Global Note directly through DTC if they are
participants in such system, or indirectly through organizations which are
participants in such system.
 
    Investors may hold their interests in a Regulation S Global Note directly
through Cedel Bank or Euroclear, if they are participants in such systems, or
indirectly through organizations that are participants in such systems. Cedel
Bank and Euroclear will hold interests in the Regulation S Global Notes on
behalf of their participants through DTC.
 
    So long as DTC, or its nominee, is the registered owner or holder of a
Global Note, DTC or such nominee, as the case may be, will be considered the
sole owner or holder of the Notes represented by such Global Note for all
purposes under the Indenture and the Notes. No beneficial owner of an interest
in a Global Note will be able to transfer that interest except in accordance
with DTC's applicable procedures, in addition to those provided for under the
Indenture and, if applicable, those of Euroclear and Cedel Bank.
 
    Payments of the principal of, and interest on, a Global Note will be made to
DTC or its nominee, as the case may be, as the registered owner thereof. Neither
the Company, the Trustee nor any Paying Agent will have any responsibility or
liability for any aspect of the records relating to or payments made on account
of beneficial ownership interests in a Global Note or for maintaining,
supervising or reviewing any records relating to such beneficial ownership
interests.
 
    The Company expects that DTC or its nominee, upon receipt of any payment of
principal or interest in respect of a Global Note, will credit participants'
accounts with payments in amounts proportionate to their respective beneficial
interests in the principal amount of such Global Note as shown on the records of
DTC or its nominee. The Company also expects that payments by participants to
owners of beneficial interests in such Global Note held through such
participants will be governed by standing instructions and customary practices,
as is now the case with securities held for the accounts of customers registered
in the names of nominees for such customers. Such payments will be the
responsibility of such participants.
 
    Transfers between participants in DTC will be effected in the ordinary way
in accordance with DTC rules and will be settled in same-day funds. Transfers
between participants in Euroclear and Cedel Bank will be effected in the
ordinary way in accordance with their respective rules and operating procedures.
 
                                       96
<PAGE>
    The Company expects that DTC will take any action permitted to be taken by a
holder of Notes (including the presentation of Notes for exchange as described
below) only at the direction of one or more participants to whose account the
DTC interests in a Global Note are credited and only in respect of such portion
of the aggregate principal amount of Notes as to which such participant or
participants has or have given such direction. However, if there is an Event of
Default under the Notes, DTC will exchange the applicable Global Note for
Certificated Notes, which it will distribute to its participants and which may
be legended as set forth under the heading "Transfer Restrictions."
 
    The Company understands that DTC is a limited purpose trust company
organized under the laws of the State of New York, a "banking organization"
within the meaning of New York Banking Law, a member of the Federal Reserve
System, a "clearing corporation" within the meaning of the Uniform Commercial
Code and a "Clearing Agency" registered pursuant to the provisions of Section
17A of the Exchange Act. DTC was created to hold securities for its participants
and facilitate the clearance and settlement of securities transactions between
participants through electronic book-entry changes in accounts of its
participants, thereby eliminating the need for physical movement of certificates
and certain other organizations. Indirect access to the DTC system is available
to others such as banks, brokers, dealers and trust companies that clear through
or maintain a custodial relationship with a participant, either directly or
indirectly ("indirect participants").
 
    Although DTC, Euroclear and Cedel Bank are expected to follow the foregoing
procedures in order to facilitate transfers of interests in a Global Note among
participants of DTC, Euroclear and Cedel Bank, they are under no obligation to
perform or continue to perform such procedures, and such procedures may be
discontinued at any time. Neither the Company nor the Trustee will have any
responsibility for the performance by DTC, Euroclear or Cedel Bank or their
respective participants or indirect participants of their respective obligations
under the rules and procedures governing their operations.
 
    If DTC is at any time unwilling or unable to continue as a depositary for
the Global Notes and a successor depositary is not appointed by the Company
within 90 days, the Company will issue Certificated Notes, which may bear the
legend referred to under "Transfer Restrictions," in exchange for the Global
Notes. Holders of an interest in a Global Note may receive Certificated Notes,
which may bear the legend referred to under "Transfer Restrictions," in
accordance with DTC's rules and procedures in addition to those provided for
under the Indenture.

                     CERTAIN UNITED STATES TAX CONSEQUENCES
 
    The following summary describes certain United States federal income and
estate tax consequences resulting from the purchase, ownership, and disposition
of Notes as of the date hereof. It deals only with Notes held as capital assets
by initial purchasers who purchased Notes at the initial issue price. Further,
this discussion does not address the situation of persons who may be subject to
special tax rules, including, by way of illustration and not limitation, rules
applicable to dealers in securities or currencies, financial institutions,
tax-exempt entities, life insurance companies, persons who hold Notes as a
hedge, as part of a constructive sale, or as a position in a "straddle" for
income tax purposes, or to persons who have a "functional currency" other than
the U.S. Dollar. As used herein, a "United States Holder" means a beneficial
owner who is a citizen or resident of the United States, a corporation, limited
liability company or partnership (unless the Treasury regulations provide
otherwise) created or organized in or under the laws of the United States or any
political subdivision thereof, an estate the income of which is subject to U.S.
federal income taxation regardless of its source, or a trust which is subject to
the supervision of a court within the United States and the control of one or
more U.S. persons as described in Section 7701(a)(30) of the Code. As used
herein, the term "Non-United States Holder" means any person or entity that is
not a United States Holder. An individual may, subject to certain exceptions, be
deemed to be a resident (as opposed to a non-resident alien) of the United
States by virtue of being present in the United States on at least 31 days in
the calendar year and for an aggregate of at least 183 days during a three year
period ending in the current calendar year, determined by counting each day
present in the U.S. during the current calendar year as a full day, each day
present in the U.S. during the immediately preceding calendar year as one-third
of a day, and each day present in the U.S. during the second preceding year as
one-sixth of a day.
 
    The discussion set forth below is based upon the provisions of the Code, the
Treasury Regulations, and administrative and judicial decisions thereunder as of
the date hereof, and such authorities may be repealed, revoked or modified with
possible retroactive effect so as to result in federal income tax consequences
different from those discussed below. This summary does not purport to cover all
possible tax consequences associated with the purchase, ownership, and
disposition of Notes, such as any applicable foreign, state, local, or other tax
laws, nor to address all relevant estate or gift tax considerations. PERSONS
CONSIDERING THE PURCHASE, OWNERSHIP, OR DISPOSITION OF NOTES SHOULD CONSULT
THEIR OWN TAX ADVISORS CONCERNING THE FEDERAL INCOME TAX CONSEQUENCES IN LIGHT
OF THEIR PARTICULAR SITUATIONS AS WELL AS ANY CONSEQUENCES ARISING UNDER THE
LAWS OF ANY OTHER TAXING JURISDICTION.
 
TAX CONSEQUENCES TO UNITED STATES HOLDERS
 
    INTEREST ON THE NOTES
 
    The Notes were not issued with original issue discount ("OID"). Except as
described below, interest on a Note will be taxable to a United States Holder as
ordinary income from domestic cources at the time it is paid or accrued in
accordance with the United States Holder's regular method of accounting for
United States tax purposes.
 
    SALE, RETIREMENT, OR OTHER DISPOSITION OF NOTES
 
    Upon the sale, retirement, or other disposition of a Note (including any
sale to the Company in connection with the Company's option to purchase the
Note), a holder will recognize gain or loss equal to the difference between the
amount realized on the sale, retirement, or other disposition and the holder's
tax basis in the Note. Such gain or loss will be capital gain or loss and will
be long-term capital gain or loss if, at the time of the sale, retirement, or
other disposition, the Note has been held for more than one year. The Taxpayer
Relief Act of 1997 includes substantial changes to the federal taxation of
capital gains recognized by certain noncorporate taxpayers, such as individuals,
including a 20% maximum tax rate for
 
                                       98
<PAGE>
certain gains from the sale of capital assets held for more than 18 months. The
deductibility of capital losses is subject to certain limitations. A holder's
tax basis in a Note will, in general, equal the cost of the Note to the holder.
 
TAX CONSEQUENCES TO NON-UNITED STATES HOLDERS
 
    INTEREST ON NOTES
 
    Subject to the discussion below concerning backup withholding, no
withholding of United States federal income tax will be required with respect to
the payment by the Company or any paying agent of principal or interest on a
Note owned by a Non-United States Holder, provided that the beneficial owner (i)
does not actually or constructively own 10% or more of the total combined voting
power of all classes of stock of the Company entitled to vote within the meaning
of Section 871(h)(3) of the Code and the regulations thereunder, (ii) is not a
controlled foreign corporation related, directly or indirectly, to the Company
through stock ownership, (iii) is not a bank whose receipt of interest on a Note
is described in Section 881(c)(3)(A) of the Code and (iv) satisfies the
statement requirement (described generally below) set forth in Section 871(h)
and Section 881(c) of the Code and the regulations thereunder.
 
    To satisfy the requirement referred to in clause (iv) above, the beneficial
owner of such Note, or a financial institution holding the Note on behalf of
such owner, must provide, in accordance with specified procedures, the Company
or its paying agent with a statement to the effect that the beneficial owner is
not a U.S. person. These requirements will be met if (1) the beneficial owner
provides his name and address, and certifies, under penalties of perjury, that
he is not a U.S. person (which certification may be made on an IRS Form W-8 (or
successor form)) or (2) a financial institution holding the Note on behalf of
the beneficial owner certifies, under penalties of perjury, that such statement
has been received by it and furnishes a paying agent with a copy thereof. Under
finalized Treasury Regulations, the statement requirement referred to in clause
(iv) above may also be satisfied with other documentary evidence for interest
paid after December 31, 1999 with respect to an offshore account or through
certain foreign intermediaries.
 
    In the event any of the above requirements are not satisfied, the Company
will nonetheless not withhold federal income tax on interest paid to a
Non-United States Holder if it receives IRS Form 4224 (or successor form) from
the Non-United States Holder, establishing that such income is effectively
connected with the conduct of a trade or business in the United States, unless
the Company has knowledge to the contrary. Interest paid to a Non-United States
Holder (other than a partnership) which is effectively connected with the
conduct by the holder of a trade or business in the United States is generally
taxed at the graduated rates that are applicable to United States persons. In
the case of a Non-United States Holder that is a corporation, such effectively
connected income may also be subject to the United States federal branch profits
tax (which is generally imposed on a foreign corporation on the deemed
repatriation from the United States of effectively connected earnings and
profits) at a 30% rate (unless the rate is reduced or eliminated by an
applicable income tax treaty and the holder is a qualified resident of the
treaty country). In the case of a partnership that has foreign partners (i.e.,
persons who would be Non-United States Holders if they held the Notes directly),
such effectively connected income allocable to the foreign partner would
generally be subject to United Stated federal withholding tax (regardless of
whether such income is, in fact, distributed to such foreign partner) at a 35%
rate if the foreign partner is a corporation, or at a 39.6% rate if the foreign
partner is not a corporation. Any foreign partner of such a partnership would be
entitled to a credit against his United States federal income tax for his share
of the withholding tax paid by the partnership.
 
    If a Non-United States Holder cannot satisfy the requirements of any of the
above-described exceptions to withholding, payments of interest made to a
Non-United States Holder will be subject to a 30% withholding tax unless the
beneficial owner of the Note provides the Company or its paying agent, as
 
                                       99
<PAGE>
the case may be, with a properly executed IRS Form 1001 (or successor form)
claiming an exemption from or reduced rate of withholding under the benefit of
an applicable tax treaty.
 
    Under the Final Regulations, Non-United States Holders will generally be
required to provide IRS Form W-8 in lieu of IRS Form 4224 or IRS Form 1001,
although alternative documentation may be applicable in certain situations.
 
    SALE, EXCHANGE, REDEMPTION OR OTHER DISPOSITION OF NOTES
 
    A Non-United States Holder will generally not be subject to United States
federal income tax with respect to gain recognized on a sale, exchange,
redemption or other disposition of Notes unless (i) the gain is effectively
connected with a trade or business of the Non-United States Holder in the United
States, (ii) in the case of a Non-United States Holder who is an individual and
holds the Notes as a capital asset, such holder is present in the United States
for 183 or more days in the taxable year of the sale or other disposition and
certain other conditions are met, or (iii) the Non-United States Holder is
subject to tax pursuant to certain provisions of the Code applicable to United
States expatriates. Subject to the discussion below concerning backup
withholding, no withholding of United States federal income tax will be required
with respect to any gain or income realized by a Non-United States Holder upon
the sale, exchange, retirement or other disposition of a Note.
 
    Gains derived by a Non-United States Holder (other than a partnership) from
the sale or other disposition of Notes that are effectively connected with the
conduct by the Holder of a trade or business in the United States are generally
taxed at the graduated rates that are applicable to United States persons. In
the case of a Non-United States Holder that is a corporation, such effectively
connected income may also be subject to the United States branch profits tax. In
the case of a partnership that has foreign partners (i.e., persons who would be
Non-United States Holders if they held the Notes directly) withholding will be
made at a 35% rate if the foreign partner is a corporation, or at 39.6% rate if
the foreign partner is not a corporation. Any foreign partner of such a
partnership would be entitled to a credit against his United States federal
income tax for his share of the withholding tax paid by the partnership. If an
individual Non-United States Holder falls under clause (ii) of the immediately
preceding paragraph of this discussion, he will be subject to a flat 30% tax on
the gain derived from the sale or other disposition, which may be offset by
United States capital losses recognized within the same taxable year as such
sale or other disposition (notwithstanding the fact that he is not considered a
resident of the United States).
 
    FEDERAL ESTATE TAX
 
    A Note beneficially owned by an individual who at the time of death is a
Non-United States Holder will not be subject to United States federal estate tax
as a result of such individual's death, provided that such individual does not
actually or constructively own 10% or more of the total combined voting power of
all classes of stock of the Company entitled to vote within the meaning of
Section 871(h)(3) of the Code and provided that the interest payments with
respect to such Note would not have been, if received at the time of such
individual's death, effectively connected with the conduct of a United States
trade or business by such individual.
 
INFORMATION REPORTING AND BACKUP WITHHOLDING
 
    In general, information reporting requirements will apply to certain
payments of principal and interest on the Notes and to the proceeds of sale of a
Note made to United States Holders other than certain exempt recipients (such as
corporations). A 31% backup withholding tax will apply to such payments if the
United States Holder fails to provide a taxpayer identification number or
certification of foreign or other exempt status or fails to report in full
dividend and interest income.
 
    No information reporting or backup withholding will be required with respect
to payments made by the Company or any paying agent to Non-United States Holders
if a statement described in clause
 
                                      100
<PAGE>
(iv) under "Tax Consequences to Non-United States Holders--Interest on Notes"
has been received and the payor does not have actual knowledge that the
beneficial owner is a United States person.
 
    Information reporting and backup withholding will not apply if payments of
interest on a Note are made outside the United States to an account maintained
at an office or branch of a United States or foreign bank or other financial
institution, provided certain procedures are in place, and are observed, between
the Company and the foreign bank or financial institution.
 
    Payments on the sale, exchange or other disposition of a Note made to or
through a foreign office of a broker generally will not be subject to backup
withholding. However, payments made by a broker that is a United States person,
a controlled foreign corporation for United States federal income tax purposes,
a foreign person 50 percent or more of whose gross income is effectively
connected with a United States trade or business for a specified three year
period, or (with respect to payments after December 31, 1999) a foreign
partnership with certain connections to the United States, will be subject to
information reporting unless the broker has in its records documentary evidence
that the beneficial owner is not a United States person and certain other
conditions are met, or the beneficial owner otherwise establishes an exemption.
Backup withholding may apply to any payment that such broker is required to
report if the broker has actual knowledge that the payee is a United States
person. Payments to or through the United States office of a custodian, nominee
or agent or the payment by the United States office of a broker of the proceeds
of a sale will be subject to information reporting and backup withholding unless
the Holder certifies, under penalties of perjury, that it is not a United States
person or otherwise establishes an exemption.
 
    For payments made after December 31, 1999, with respect to Notes held by
foreign partnerships, Treasury regulations require that the certification
described in (iv) under "Tax Consequences to Non-United States Holders--Interest
on Notes" above be provided by the partners, rather than by the foreign
partnership, and that the partnership provide certain information, including a
United States taxpayer identification number. A look-through rule will apply in
the case of tiered partnerships.
 
    Non-United States Holders should consult their tax advisors regarding the
application of information reporting and backup withholding in their particular
situations, the availability of an exemption therefrom, and the procedures for
obtaining such an exemption, if available. Any amounts withheld under the backup
withholding rules will be allowed as a refund or credit against the Non-United
States Holder's U.S. federal income tax liability and may entitle such Holder to
a refund, provided the required information is furnished to the IRS.
 
EFFECT OF EXCHANGE
 
    The exchange of Old Notes for New Notes in the Exchange Offer should not
constitute a taxable event to holders. Consequently, no gain or loss will be
recognized by a holder upon receipt of an Exchange Note, the holding period of
the New Note will include the holding period of the Old Note exchanged therefor,
and the basis of the New Note will be the same as the basis of the Note
immediately before the exchange. In any event, persons considering the exchange
of Old Notes for New Notes should consult their own tax advisors concerning the
United States federal income tax consequences in light of their particular
situations as well as any consequences arising under the laws of any other
taxing jurisdiction.
 
                                      101
<PAGE>
                              PLAN OF DISTRIBUTION
 
    There has previously been only a limited secondary market and no public
market for the Old Notes. The Company does not intend to apply for the listing
of the Notes on a national securities exchange or for their quotation through
The Nasdaq Stock Market. The Notes are eligible for trading in the PORTAL
market. The Company has been advised by the Initial Purchaser that the Initial
Purchaser currently intends to make a market in the Notes; however, the Initial
Purchaser is not obligated to do so and any market making may be discontinued by
any Placement Agent at any time. In addition, such market making activity may be
limited during the Exchange Offer. Therefore, there can be no assurance that an
active market for the Old Notes or the New Notes will develop. If a trading
market does not develop or is not maintained, holders of Notes may experience
difficulty in reselling Notes. If a trading market develops for the Notes,
future trading prices of such securities will depend on many factors, including,
among other things, prevailing interest rates, the Company's results of
operations and the market for similar securities. Depending on such factors,
such securities may trade at a discount from their offering price.
 
    BROKER-DEALERS WHO DID NOT ACQUIRE OLD NOTES AS A RESULT OF MARKET MAKING
ACTIVITIES OR TRADING ACTIVITIES MAY NOT PARTICIPATE IN THE EXCHANGE OFFER.
 
    With respect to resale of New Notes, based on an interpretation by the staff
of the Commission set forth in no-action letters issued to third parties, the
Company believes that a holder (other than a person that is an affiliate of the
Company within the meaning of Rule 405 under the Securities Act or a "broker" or
"dealer" registered under the Exchange Act) who exchanges Old Notes for New
Notes in the ordinary course of business and who is not participating, does not
intend to participate, and has no arrangement or understanding with any person
to participate, in the distribution of the New Notes, will be allowed to resell
the New Notes to the public without further registration under the Securities
Act and without delivering to the purchasers of the New Notes a prospectus that
satisfies the requirements of Section 10 thereof. However, if any holder
acquires New Notes in the Exchange Offer for the purpose of distributing or
participating in a distribution of the New Notes, such holder cannot rely on the
position of the staff of the Commission enunciated in EXXON CAPITAL HOLDINGS
CORPORATION (available May 13, 1988) or similar no-action letters or any similar
interpretive letters and must comply with the registration and prospectus
delivery requirements of the Securities Act in connection with a secondary
resale transaction, unless an exemption from registration is otherwise
available.
 
    As contemplated by the no-action letters mentioned above and the
Registration Rights Agreement, each holder accepting the Exchange Offer is
required to represent to the Company in the Letter of Transmittal that (i) the
New Notes are to be acquired by the holder in the ordinary course of business,
(ii) the holder is not engaging and does not intend to engage in the
distribution of the New Notes, and (iii) the holder acknowledges that, if such
holder participates in the Exchange Offer for the purpose of distributing the
New Notes, such holder must comply with the registration and prospectus delivery
requirements of the Securities Act and cannot rely on the above no-action
letters.
 
    Any broker or dealer registered under the Exchange Act (each a
"Broker-Dealer") who holds Old Notes that were acquired for its own account as a
result of market-making activities or other trading activities (other than Old
Notes acquired directly from the Company or an affiliate of the Company) may
exchange such Old Notes for New Notes pursuant to the Exchange Offer; however,
such Broker-Dealer may be deemed an underwriter within the meaning of the
Securities Act and, therefore, must deliver a prospectus meeting the
requirements of the Securities Act in connection with any resales of the New
Notes received by it in the Exchange Offer, which prospectus delivery
requirement may be satisfied by the delivery by such Broker-Dealer of this
Prospectus. The Company has agreed to cause the Exchange Offer Registration
Statement, of which this Prospectus is a part, to remain continuously effective
for a period of 180 days, if required, from the Exchange Date, and to make this
Prospectus, as amended or supplemented, available to any such Broker-Dealer for
use in connection with resales. Any Broker-Dealer participating in
 
                                      102
<PAGE>
the Exchange Offer will be required to acknowledge that it will deliver a
prospectus meeting the requirements of the Securities Act in connection with any
resales of New Notes received by it in the Exchange Offer. The delivery by a
Broker-Dealer of a prospectus in connection with resales of New Notes shall not
be deemed to be an admission by such Broker-Dealer that it is an underwriter
within the meaning of the Securities Act. The Company will not receive any
proceeds from any sale of New Notes by a Broker-Dealer.
 
    New Notes received by Broker-Dealers for their own account pursuant to the
Exchange Offer may be sold from time to time in one or more transactions in the
over-the-counter market, in negotiated transactions, through the writing of
options on the New Notes or a combination of such methods of resale, at market
prices prevailing at the time of resale, at prices related to such prevailing
market prices or negotiated prices. Any such resale may be made directly to
purchasers or to or through brokers or dealers who may receive compensation in
the form of commissions or concessions from any such Broker-Dealer and/or the
purchasers of any such New Notes.
 
                                 LEGAL MATTERS
 
    Certain legal matters with respect to the validity of the Notes are being
passed upon for the Company by McAfee & Taft A Professional Corporation,
Oklahoma City, Oklahoma.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Board of Directors
of Continental Resources, Inc.:
 
We have audited the accompanying consolidated balance sheets of Continental
Resources, Inc. (an Oklahoma corporation) and subsidiary as of December 31, 1997
and 1996, and the related consolidated statements of operations, stockholders'
equity and cash flows for each of the three years in the period ended December
31, 1997. These consolidated financial statements and the supplementary
information referred to below 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 Continental
Resources, Inc. and subsidiary as of December 31, 1997 and 1996, and the results
of their operations and their cash flows for each of the three years in the
period ended December 31, 1997, in conformity with generally accepted accounting
principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. ORGANIZATION:
 
    Continental Resources, Inc. ("CRI") was incorporated in Oklahoma on November
16, 1967, as Shelly Dean Oil Company. On September 23, 1976, the name was
changed to Hamm Production Company. In January 1987, the Company acquired all of
the assets and assumed the debt of Continental Trend Resources, Inc. Affiliated
entities, J.S. Aviation and Wheatland Oil Co. were merged into Hamm Production
Company, and the corporate name was changed to Continental Trend Resources, Inc.
at that time. In 1991, the Company's name was changed to Continental Resources,
Inc.
 
    The Company has one wholly-owned subsidiary, Continental Gas, Inc. ("CGI").
CGI was incorporated in April 1990.
 
    CRI's principal business is oil and natural gas exploration, development and
production. CRI has interests in approximately 1,000 wells and serves as the
operator in the majority of such wells. CRI's operations are primarily in
Oklahoma, North Dakota, South Dakota, Montana, Illinois and Texas.
 
    CGI is engaged principally in natural gas marketing, gathering and
processing activities and operates six gas gathering systems and two gas
processing plants in Oklahoma. In addition, CGI participates with CRI in certain
oil and natural gas wells.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
    BASIS OF PRESENTATION
 
    The accompanying consolidated financial statements include the accounts and
operations of CRI and CGI (collectively the "Company"). All significant
intercompany accounts and transactions have been eliminated in the consolidated
financial statements.
 
    INTERIM FINANCIAL INFORMATION
 
    The interim consolidated financial statements as of March 31, 1998, and for
the three months ended March 31, 1997 and 1998, are unaudited, and certain
information and footnote disclosures normally included in financial statements
prepared in accordance with generally accepted accounting principals have been
omitted. In the opinion of management, all adjustments, consisting of normal
recurring adjustments, necessary to fairly present the financial position,
results of operations and cash flows with respect to the consolidated interim
financial statements have been included.
 
    ACCOUNTS RECEIVABLE
 
    The Company operates exclusively in the oil and natural gas exploration and
production, gas gathering and processing and gas marketing industries. The
Company's joint interest receivables at December 31, 1996 and 1997, are recorded
net of an allowance for doubtful accounts of approximately $200,000 and
$467,000, respectively, in the accompanying consolidated balance sheets.
 
    INVENTORIES
 
    Inventories consist primarily of tubular goods, production equipment and
crude oil in tanks, which are stated at the lower of average cost or market. At
December 31, 1996 and 1997, tubular goods and production equipment totaled
approximately $2,773,000 and $2,692,000, respectively; crude oil in tanks
totaled approximately $783,000 and $856,000, respectively.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
    PROPERTY AND EQUIPMENT
 
    The Company utilizes the successful efforts method of accounting for oil and
gas activities whereby costs to acquire mineral interests in oil and gas
properties, to drill and equip exploratory wells that find proved reserves and
to drill and equip development wells are capitalized. These costs are amortized
to operations on a unit-of-production method based on proved developed oil and
gas reserves, allocated property by property, as estimated by petroleum
engineers. Geological and geophysical costs, lease rentals and costs associated
with unsuccessful exploratory wells are expensed as incurred. Nonproducing
leaseholds are periodically assessed for impairment based on exploration results
and planned drilling activity. Maintenance and repairs are expensed as incurred,
except that the costs of replacements or renewals that expand capacity or
improve production are capitalized. Gas gathering systems and gas processing
plants are depreciated using the straight-line method over an estimated useful
life of 14 years. Service properties and equipment and other is depreciated
using the straight-line method over estimated useful lives of 5 to 40 years.
 
    INCOME TAXES
 
    The Company filed a consolidated income tax return based on a May 31 fiscal
tax year end. Through May 31, 1997, deferred income taxes were provided for
temporary differences between financial reporting and income tax bases of assets
and liabilities. The estimated Federal and state income taxes on income or loss
generated between June 1 and December 31 is included in deferred income taxes at
each calendar year end prior to December 31, 1997.
 
    Effective June 1, 1997, the Company converted to an "S-corporation" under
Subchapter S of the Internal Revenue Code. As a result, income taxes
attributable to Federal taxable income of the Company after May 31, 1997, if
any, will be payable by the stockholders of the Company. The effect of
eliminating the deferred tax assets and liabilities were recognized in the
results of operations for the year ended December 31, 1997, the year of
adoption.
 
    EARNINGS PER COMMON SHARE
 
    Earnings per common share includes no dilution and is computed by dividing
income available to common stockholders by the weighted-average number of shares
outstanding for the period. There are no common stock equivalents or securities
outstanding which would result in material dilution. The weighted-average number
of shares used to compute earnings per common share was 49,045 in 1995 and 1996
and 49,042 in 1997.
 
    FUTURES CONTRACTS
 
    CGI, in the normal course of business, enters into fixed price contracts for
either the purchase or sale of natural gas at future dates. Due to fluctuations
in the natural gas market, CGI buys or sells natural gas futures contracts to
hedge the price and basis risk associated with the specifically identified
purchase or sales contracts. CGI accounts for changes in the market value of
futures contracts as a deferred gain or loss until the production month of the
hedged transaction, at which time the gain or loss on the natural gas futures
contract is recognized in the results of operations. At December 31, 1996 and
1997, there were no open natural gas futures contracts. Net gains and losses on
futures contracts are included in gas gathering,

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
marketing and processing revenues in the accompanying consolidated statements of
operations and were immaterial for the years ended December 31, 1995, 1996 and
1997.
 
    GAS BALANCING ARRANGEMENTS
 
    The Company follows the "sales method" of accounting for its gas revenue
whereby the Company recognizes sales revenue on all gas sold to its purchasers,
regardless of whether the sales are proportionate to the Company's ownership in
the property. A liability is recognized only to the extent that the Company has
a net imbalance in excess of their share of the reserves in the underlying
properties. The Company's aggregate imbalance positions at December 31, 1996 and
1997 were not material.
 
    SIGNIFICANT CUSTOMER
 
    During 1995, 1996 and 1997 approximately 13.1%, 41.3% and 46.6%,
respectively, of the Company's total revenue were derived from sales made to a
single customer.
 
    FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    The Company's financial instruments consist primarily of cash, trade
receivables, trade payables and bank debt. The carrying value of cash, trade
receivables and trade payables are considered to be representative of their
respective fair values, due to the short maturity of these instruments. The fair
value of bank debt approximates its carrying value based on the borrowing rates
currently available to the Company for bank loans with similar terms and
maturities.
 
    PRESENTATION
 
    Certain prior year information has been reclassified to conform to the 1997
presentation.
 
    USE OF ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates. Of the
estimates and assumptions that affect reported results, the estimate of the
Company's oil and natural gas reserves, which is used to compute depreciation,
depletion, amortization and impairment on producing oil and gas properties, is
the most significant.

(a) The line of credit with a bank allows borrowings up to $75,000,000. The
    Company has collateralized the loan with substantially all of its oil and
    natural gas interests, and gathering, marketing and processing properties.
    This loan bears interest at either Wall Street Journal Prime (8.5% at
    December 31, 1997) or Adjusted LIBOR which includes the LIBOR rate (5.9% for
    ninety day LIBOR at December 31, 1997) posted in the Wall Street Journal
    adjusted for a capacity fee. The LIBOR rate can be locked in for thirty,
    sixty or ninety days as determined by the Company through the use of various
    principal tranches; or the Company can elect to leave the interest amount
    based on the Prime interest rate. Interest is payable monthly on Prime
    balances and at the expiration of LIBOR tranches with all outstanding
    principal and interest due at maturity on December 31, 2000.
 
(b) Throughout 1997 (May to December), CRI and CGI entered into various notes
    with the majority stockholder of the Company. These notes bear interest at
    8.25% with interest payments due monthly or quarterly for twenty-four to
    thirty-six months. On December 31, 1997, the notes between CRI and the
    majority shareholder were combined into one note totaling $21,750,000
    bearing interest at 8.25% with interest payments due on a quarterly basis
    for twenty-four months. The balance is to be paid in full by December 31,
    2002. The note between CGI and the majority shareholder bears interest at
    8.25% with interest payments due on a quarterly basis for thirty-six months.
    After the three-year period, the balance owed by CGI can be converted to an
    amortization schedule payable by November 2002. Subsequent to December 31,
    1997, the CGI note was paid in full.
 
(c) In July 1997, the Company borrowed $4,000,000 from General Electric Capital
    Corporation to finance the purchase of an airplane. The note accrues
    interest at 7.91% to be paid in one hundred nineteen (119) consecutive
    monthly installments of principal and interest of $48,341 each and a final
    installment of approximately $48,000. It is secured by the airplane.
 
(d) During 1997, the Company entered into two capital lease agreements to
    purchase a copier and computer equipment. The agreements require monthly
    payments of principal and interest for forty-two and sixty months,
    respectively.

4. INCOME TAXES:
 
    The Company follows Statement of Financial Accounting Standards ("SFAS") No.
109, "Accounting for Income Taxes." As mentioned in Note 2, effective June 1,
1997, the Company converted to an S-Corporation resulting in the taxable income
or loss of the Company from that date being reported to the shareholders and
included in their respective Federal and state income tax returns. Accordingly,
the deferred income tax assets and liabilities at May 31, 1997, were eliminated
through recording a provision for income tax benefit. The components of income
tax expense (benefit) are as follows:

5. COMMITMENTS AND CONTINGENCIES:
 
    The Company maintains a defined contribution pension plan for its employees
under which it contributes to the plan 4% of the annual compensation of all
employees at least 21 years old with a minimum of six months service. Pension
expense for the years ended December 31, 1995, 1996 and 1997, was approximately
$144,000, $152,000 and $242,000, respectively.
 
    The Company and other affiliated companies participate jointly in a
self-insurance pool (the "Pool") covering health and workers' compensation
claims made by employees up to the first $50,000 and $500,000, respectively, per
claim. Any amounts paid above these are reinsured through third-party providers.
Premiums charged to the Company are based on estimated costs per employee of the
Pool. Premiums are expensed as incurred. No additional premium assessments are
anticipated for periods prior to December 31, 1997. Property and general
liability insurance is maintained through third-party providers with a $50,000
deductible on each policy.
 
    The Company is involved in various legal proceedings in the normal course of
business, none of which, in the opinion of management, will have a material
adverse effect on the financial position or results of operations of the
Company. The Company has been successful in Federal courts in its lawsuit
against a gas purchaser arising from tortious interference with business
relations. A judgment was awarded for actual and punitive damages under the
Federal lawsuit totaling $30,269,000 plus accrued interest. In May 1996, this
decision was remanded by the U.S. Supreme Court back to the Tenth Circuit Court
of Appeals for further consideration. No amounts were included in the
accompanying financial statements for this judgment as the ultimate outcome was
uncertain at December 31, 1996. During 1997, this lawsuit was settled with an
aggregate judgment of $9,500,000 of which the Company's share was approximately
$7,500,000. It is included in other income in the accompanying statement of
operations for the year ended December 31, 1997.
 
    Due to the nature of the oil and gas business, the Company is exposed to
possible environmental risks. The Company has implemented various policies and
procedures to avoid environmental contamination and risks from environmental
contamination. The Company is not aware of any material potential environmental
issues or claims.

6. RELATED PARTY TRANSACTIONS:
 
    The Company, acting as operator on certain properties, utilizes affiliated
companies to provide oilfield services such as drilling and trucking. The total
amount paid to these companies, a portion of which is billed to other interest
owners, was approximately $5,899,000, $5,870,000 and $11,852,000 during the
years ended December 31, 1995, 1996 and 1997, respectively. These services are
provided at amounts which management believes approximate the costs which would
have been paid to an unrelated party for the same services. At December 31, 1996
and 1997, the Company owed approximately $826,000 and $1,094,000, respectively,
to these companies which is included in accounts payable and accrued liabilities
in the accompanying consolidated balance sheets. These companies and other
companies owned by the Company's majority stockholder also own interests in
wells operated by the Company. At December 31, 1996 and 1997, approximately
$461,000 and $336,000, respectively, from affiliated companies is included in
joint interest accounts receivable in the accompanying consolidated balance
sheets.
 
    Beginning in 1996, a portion of the Company's Oklahoma, South Dakota, North
Dakota and Montana crude oil production sold by the Company to an unrelated
third party purchaser was resold to an affiliate of the Company.
 
    During the years ended December 31, 1996 and 1997, the Company and CGI
advanced certain amounts to affiliates primarily for operating expenditures. The
advances outstanding to affiliates at December 31, 1996 and 1997, totaled
approximately $461,000 and $60,000, respectively. Interest income earned during
the years ended December 31, 1995, 1996 and 1997, was approximately $13,000,
$33,000 and $33,000, respectively, on advances to affiliates.
 
    The Company leases office space under operating leases directly or
indirectly from the majority stockholder. Rents paid associated with these
leases totaled approximately $228,000, $232,000 and $294,000 for the years ended
December 31, 1995, 1996 and 1997, respectively.
 
    During 1997, advances were made to the Company from the majority
stockholder. Interest paid or accrued during the year related to these advances
totaled approximately $744,000.
 
7. IMPAIRMENT OF LONG-LIVED ASSETS:
 
    In March 1995, the Financial Accounting Standards Board issued SFAS No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
Be Disposed Of." The Company adopted SFAS No. 121 in the year ended December 31,
1996. During 1996 and 1997, the Company reviewed its oil and gas properties
which are maintained under the successful efforts method of accounting, to
identify properties with excess of net book value over projected future net
revenue of such properties. Any such excess net book values identified were
evaluated further considering such factors as future price escalation,
probability of additional oil and gas reserves and a discount to present value.
If an impairment was determined appropriate an additional charge was added to
depreciation, depletion and amortization ("DD&A") expense. The Company
recognized additional DD&A impairment in 1996 and 1997 of approximately
$2,100,000 and $5,000,000, respectively.

    Proved reserves are estimated quantities of crude oil, natural gas and
natural gas liquids which geological and engineering data demonstrate with
reasonable certainty to be recoverable in future years from known reservoirs
under existing economic and operating conditions.
 
    There are numerous uncertainties inherent in estimating quantities of proved
oil and gas reserves. Oil and gas reserve engineering is a subjective process of
estimating underground accumulations of oil and gas that cannot be precisely
measured, and estimates of engineers other than the Company's might differ
materially from the estimates set forth herein. The accuracy of any reserve
estimate is a function of the quality of available data and of engineering and
geological interpretation and judgment. Results of drilling, testing and
production subsequent to the date of the estimate may justify revision of such
estimate. Accordingly, reserve estimates are often different from the quantities
of oil and gas that are ultimately recovered.
 
    Gas imbalance receivables and liabilities for each of the three years ended
December 31, 1995, 1996 and 1997, were not material and have not been included
in the reserve estimates.

STANDARDIZED MEASURE OF DISCOUNTED FUTURE NET CASH FLOWS RELATING TO PROVED OIL
  AND GAS RESERVES (UNAUDITED)
 
    The following information is based on the Company's best estimate of the
required data for the Standardized Measure of Discounted Future Net Cash Flows
as of December 31, 1995, 1996, and 1997 as required by Financial Accounting
Standards Board's Statement of Financial Accounting Standards No. 69. The
Standard requires the use of a 10 percent discount rate. This information is not
the fair market value nor does it represent the expected present value of future
cash flows of the Company's proved oil and gas reserves (in thousands of
dollars).

    Future cash inflows are computed by applying year-end prices of oil and gas
relating to the Company's proved reserves to the year-end quantities of those
reserves. The year-end weighted average oil price utilized in the computation of
future cash inflows was approximately $18.06 per BBL at December 31, 1997 and
$23.00 per BBL at December 31, 1995 and 1996. The year-end weighted average gas
price utilized in the computation of future cash inflows was approximately $2.25
per MCF at December 31, 1997 and $3.28 per MCF at December 31, 1995 and 1996.

8. SUPPLEMENTAL OIL AND GAS INFORMATION (UNAUDITED): (CONTINUED)
    Future production and development costs, which include dismantlement and
restoration expense, are computed by estimating the expenditures to be incurred
in developing and producing the Company's proved oil and gas reserves at the end
of the year, based on year-end costs, and assuming continuation of existing
economic conditions.
 
    Future income tax expenses are computed by applying the appropriate year-end
statutory tax rates to the future pretax net cash flows relating to the
Company's proved oil and gas reserves, less the tax bases of the properties
involved. The future income tax expenses give effect to tax credits and
allowances, but do not reflect the impact of general and administrative costs
and exploration expenses of ongoing operations relating to the Company's proved
oil and gas reserves. Income taxes were not computed at December 31, 1997, as
the Company elected S-Corporation status effective June 1, 1997.

net cash flows attributable to the Company's proved oil and gas reserves at

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Continental Resources, Inc.:
 
We have audited the accompanying statements of revenues and direct operating
expenses of the oil and gas properties included in the Purchase Agreement
between Continental Resources Inc. and Bass Enterprises Production Co. (the
"Properties") for the three years in the period ended December 31, 1997. These
statements are the responsibility of Continental Resources management. Our
responsibility is to express an opinion on these 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 statements of revenues and direct
operating expenses are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the statements of revenues and direct operating expenses. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall statement presentation. We believe
that our audits provide a reasonable basis for our opinion.
 
The accompanying statements of revenues and direct operating expenses were
prepared in connection with the purchase of the Properties and, as described in
Note 1, exclude general and administrative expenses, depreciation, depletion and
amortization, interest, income tax expenses, and other items as these expenses
would not be comparable to those resulting from the proposed future operations
of the Properties.
 
In our opinion, the statements of revenues and direct operating expenses
referred to above present fairly, in all material respects, the revenues and
direct operating expenses of the Properties for the three years in the period
ended December 31, 1997.

1. BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES:
 
    BASIS OF PRESENTATION
 
    The accompanying statements present revenues and direct operating expenses
of working and royalty interests in oil and gas properties located near the town
of Worland in the Bighorn Basin of Wyoming included in the Purchase Agreement
between Continental Resources, Inc. ("Continental") and Bass Enterprises
Production Co., adjusted for Continental's sale of a 50% interest in the oil and
gas properties to Continental's majority shareholder (the "Properties").
 
    The accompanying statements of revenues and direct operating expenses were
prepared on the accrual basis of accounting and relate only to the Properties
described above. These historical results may not be indicative of future
operations. The statements do not include general and administrative expenses,
interest, depreciation, depletion and amortization, Federal and state income
taxes and other items because such amounts would not be indicative of those
expenses which will be incurred by Continental.
 
    The unaudited statements of revenues and direct operating expenses for the
three-month periods ended March 31, 1997 and 1998, in the opinion of Continental
management, were prepared on a basis consistent with the audited statements of
revenues and direct operating expenses of the Properties for the three years in
the period ended December 31, 1997, and include all adjustments, consisting only
of normal recurring accruals, necessary to present fairly the revenues and
direct operating expenses for the indicated periods.
 
    USE OF ESTIMATES
 
    The preparation of the statements of revenues and direct operating expenses
in conformity with generally accepted accounting principles requires Continental
to make estimates and assumptions that affect the reported amounts of revenues
and direct operating expenses during the reporting periods. Actual results could
differ from those estimates as additional information becomes available.
 
    CONCENTRATION OF REVENUE AND LIMITED NUMBER OF CUSTOMERS
 
    Approximately 84%, 78% and 75% of revenues were derived from one property
during 1995, 1996 and 1997, respectively. In addition, virtually all of the
production of the properties was purchased by three purchasers during the
periods.

</TABLE>
 
    Proved reserves are estimated quantities of crude oil, natural gas and
natural gas liquids which geological and engineering data demonstrate with
reasonable certainty to be recoverable in future years from known reservoirs
under existing economic and operating conditions.
 
    There are numerous uncertainties inherent in estimating quantities of proved
oil and gas reserves. Oil and gas reserve engineering is a subjective process of
estimating underground accumulations of oil and gas that cannot be precisely
measured, and estimates of other engineers might differ materially from the
estimates set forth herein. The accuracy of any reserve estimate is a function
of the quality of available data and of engineering and geological
interpretation and judgment. Results of drilling, testing and production
subsequent to the date of the estimate may justify revision of such estimate.
Accordingly, reserve estimates are often different from the quantities of oil
and gas that are ultimately recovered.

    STANDARDIZED MEASURE OF DISCOUNTED FUTURE NET CASH FLOWS RELATING TO PROVED
     OIL AND GAS RESERVES (UNAUDITED)
 
    The following information is based on Continental's best estimate of the
required data for the Standardized Measure of Discounted Future Net Cash Flows
as of December 31, 1995, 1996, and 1997 as required by Financial Accounting
Standards Board's Statement of Financial Accounting Standards No. 69. The
Standard requires the use of a 10 percent discount rate. This information is not
the fair market value nor does it represent the expected present value of future
cash flows of Continental's proved oil and gas reserves (in thousands of
dollars).

</TABLE>
 
    Future cash inflows are computed by applying year-end prices of oil and gas
relating to the Properties' proved reserves to the year-end quantities of those
reserves. The year-end weighted average oil price utilized in the computation of
future cash inflows was approximately $11.44 per BBL at December 31, 1995, 1996
and 1997. The year-end weighted average gas price utilized in the computation of
future cash inflows was approximately $1.00 per MCF at December 31, 1995, 1996
and 1997.
 
    Future production and development costs, which include dismantlement and
restoration expense, are computed by estimating the expenditures to be incurred
in developing and producing the Properties' proved oil and gas reserves at the
end of the year, based on year-end 1997 costs, and assuming continuation of
existing economic conditions.

the Company, other than an action by or in the right of the Company, provided
that he acted in good faith and in a manner he reasonably believed to be in the
best interest of the Company, and with respect to any criminal action, he had no
reasonable cause to believe that his conduct was unlawful and (b) expenses
(including attorney's fees) actually and reasonably incurred by him in
connection with the defense or settlement of any action or suit by or in the
right of the Company brought by reason of his being or having been a director,
officer, employee or agent of the Company, or any other corporation,
partnership, joint venture, or other enterprise at the request of the Company,
provided that he acted in good faith and in a manner he reasonably believed to
be in or not opposed to the best interest of the Company; except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged liable to the Company, unless and
only to the extent that the court in which such action or suit was decided has
determined that the person is fairly and reasonably entitled to indemnification
for such expenses which the court shall deem proper. The Company's bylaws
provide for similar indemnification. These provisions may be sufficiently broad
to indemnify such persons for liabilities arising under the Securities Act of
1933, as amended.
 
    The Company's directors and officers are also insured against claims arising
out of the performance of their duties in such capacities.

ITEM 22. UNDERTAKINGS.
 
    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, represent 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 the 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 to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11 or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the Registration Statement through the
date of responding to the request.
 
    The undersigned Registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the Registration Statement when it became effective.
 
    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registration pursuant to the provisions described under Item 20, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnifications 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 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.

                             AMENDED AND RESTATED
                         CERTIFICATE OF INCORPORATION


          I, Randy Moeder, certify that I am the Senior Vice President and 
Secretary, of Continental Resources, Inc., a corporation organized and 
existing under the laws of the State of Oklahoma (the "Corporation"), and do 
hereby further certify as follows:

     1.   The name of this Corporation is Continental Resources, Inc.

     2.   The name under which the Corporation was originally incorporated 
was Shelly Dean Oil Co.  The original Certificate of Incorporation of the

January 30, 1987, June 21, 1991, September 30, 1991 and April 28, 1996.

     3.   This Amended and Restated Certificate of Incorporation was duly 
adopted in accordance with the provisions of Sections 1077 and 1080 of the 
Oklahoma General Corporation Act (the "Act") by the written consent of the 
holders of not less than a majority the outstanding stock of the Corporation 
entitled to vote thereon, and written notice of the corporate action has been 
given to the shareholders of the Corporation, if any, who have not so 
consented in writing, all in accordance with the provisions of the Act.

     SECOND.  The address of the registered office of the Corporation in the

address is Harold Hamm.

     THIRD.  The purpose of the Corporation is to engage in any lawful act or 
activity for which corporations may be organized under the Act.

     FOURTH.  The total number of shares of capital stock which the

75,000 shares designated as Common Stock, par value $1.00 per share, and

     The preferences, qualifications, limitations, restrictions and the 
special or relative rights in respect of the shares of each class are as 
follows:

     PREFERRED.

     The Preferred Stock may be issued from time to time in one or more 
series. All shares of 


                                       -2-

<PAGE>

Preferred Stock shall be of equal rank and shall be identical, except in 
respect of the matters that may be fixed and determined by the Board of 
Directors of the Corporation (the "Board") as hereinafter provided, and each 
share of each series shall be identical with all other shares of such series, 
except as to the date from which dividends are cumulative, if applicable.  
The Board is hereby authorized to cause such shares to be issued in one or 
more series and with respect to each such series prior to the issuance 
thereof to fix and determine the designation, powers, preferences and rights 
of the shares of each such series then the qualifications, limitations or 
restrictions thereof.

     The authority of the Board with respect to each series shall include, 
but not be limited to, determination of the following:

     (a)  The number of shares constituting that series and the distinctive 
designation of that series;

     (b)  The dividend rate on the shares of that series, whether dividends 
shall be cumulative, and if so, from which date or dates, and the relative 
rights of priority, if any, of payment of dividends on shares of that series;

     (c)  Whether that series shall have voting rights, in addition to the 
voting rights provided by law, and if so, the terms of such voting rights;

     (d)  Whether that series shall have conversion privileges, and if so, 
the terms and conditions of such conversion, including provisions for 
adjustment of the conversion rate in such events as the Board shall determine;

     (e)  Whether or not shares of that series shall be redeemable, and if 
so, the terms and conditions of such redemption, including the date or dates 
upon or after which they shall be redeemable, and the amount per share 
payable in case of redemption, which amount may vary under different 
conditions and at different redemption dates;

     (f)  Whether that series shall have a sinking fund for the redemption or 
purchase of shares of that series, and if so, the terms and amount of such 
sinking fund;

     (g)  The rights of the shares of that series in the event of voluntary 
or involuntary liquidation, dissolution and winding up of the Corporation, 
and the relative rights of priority, if any, of payment of shares of that 
series; and

     (h)  Any other relative rights, preferences or limitations of that 
series.

     Dividends on outstanding shares of Preferred Stock shall be paid or set 
apart from payment before any dividends shall be paid or declared or set 
apart for payment on the Common Stock with respect to the same dividend 
period.

     If upon any voluntary or involuntary liquidation, dissolution or winding 
up of the 


                                       -3-

<PAGE>

Corporation the assets available for distribution to holders of shares of 
Preferred Stock of all series shall be insufficient to pay such holders the 
full preferential amount to which they are entitled, then such assets shall 
be distributed ratably among the shares of all series in accordance with the 
respective preferential amounts (including unpaid cumulative dividends, if 
any) payable with respect thereto.

     COMMON.

     Each of the shares of Common Stock of the Corporation shall be equal in 
all respects to each others share.  The holders of shares of Common Stock 
shall be entitled to one vote for each share of Common Stock held with 
respect to all matters as to which the Common Stock is entitled to be voted.

     Subject to the preferential and other dividend rights applicable to 
Preferred Stock, the holders of shares of Common Stock shall be entitled to 
receive such dividends (payable in cash, stock or otherwise) as may be 
declared on the Common Stock by the Board at any time or from time to time 
out of any funds legally available therefore.

     In the event of any voluntary or involuntary liquidation, distribution 
or winding up of the Corporation, after distribution in full of the 
preferential and/or other amounts to be distributed to the holders of shares 
of Preferred Stock, the holders of shares of Common Stock shall be entitled 
to receive all of the remaining assets of the Corporation available for 
distribution to its shareholders, ratably in portion to the number of shares 
of Common Stock held by them.

     FIFTH.  A director of the Corporation shall not be personally liable to 
the Corporation or its stockholders for monetary damages for breach of 
fiduciary duty as a director, except for liability (i) for any breach of the 
director's duty of loyalty to the Corporation or its stockholders, (ii) for 
acts or omissions not in good faith or which involve intentional misconduct 
or a knowing violation of law, (iii) under Section 1053 of the Act, or 
(iv) for any transaction from which the director derived any improper 
personal benefit.  If the Act is amended after approval by the stockholders 
of this article to authorize corporate action further eliminating or limiting 
the personal liability of directors, then the liability of a director of the 
Corporation shall be eliminated or limited to the fullest extent permitted by 
the Act, as so amended.

     SIXTH.  For the purposes of this Section Sixth:

     "Continuing Director" means any member of the Board who is unaffiliated 
with the Interested Stockholder and was a member of the Board prior to the 
time that the Interested Stockholder became an Interested Stockholder, and 
any successor of a Continuing Director who is unaffiliated with the 
Interested Stockholder and is recommended to succeed a Continuing Director by 
a majority of Continuing Directors then on the Board.

     "Exchange Act" means the Securities Exchange Act of 1934, as amended.


                                       -4-

<PAGE>

     "Fair Market Value" means the highest closing price, during the 30-day 
period ending on the date in question, of the Common Stock on the principal 
securities exchange registered under the Exchange Act on which such stock is 
listed, or in the national market system maintained by the National 
Association of Securities Dealers, Inc., or, if the stock is not listed on 
any such exchange or designated as a national market system security, the 
highest closing bid quotation with respect to a share of such stock during 
the 30-day period ending on the date in question on the National Association 
of Securities Dealers, Inc. Automated Quotations System or any system then in 
use, or if no such quotations are available, the fair market value on the 
date in question of a share of such stock as determined by the Board in good 
faith.

     "Interested Stockholder" has the meaning ascribed to such term under 
Section 1090.3 of the Act.

     Any direct or indirect purchase by the Corporation, or any subsidiary of 
the Corporation, of any Common Stock, or any securities convertible to Common 
Stock, from a person or persons known by a majority of the Continuing 
Directors of the Corporation to be an Interested Stockholder, or any 
agreement in respect thereof, at a price in excess of the Fair Market Value 
shall require the affirmative vote of not less than 66 2/3% of the votes cast 
by the holders of all then outstanding shares of Common Stock, excluding for 
this purpose shares of Common Stock owned beneficially by the Interested 
Stockholder, unless a greater vote shall be required by law.

     Such affirmative vote shall not be required for a purchase or other 
acquisition of Common Stock, or any securities convertible to Common Stock, 
pursuant to an offer made on substantially the same terms to all holders of 
Common Stock, or securities convertible to Common Stock, and complying with 
the applicable requirements of the Exchange Act and the rules and regulations 
thereunder (or any subsequent provisions replacing the Exchange Act, rules or 
regulations).  Further, such affirmative vote shall not be required for any 
purchase effected on the open market and not the result of a 
privately-negotiated transaction.

     The Continuing Directors of the Corporation shall have the power and 
duty to determine for the purposes of this Section Sixth, on the basis of 
information known to them after reasonable inquiry, whether a person is an 
Interested Stockholder and the number of shares of Common Stock owned 
beneficially by any person.

     SEVENTH.  The business and affairs of the Corporation shall be under the 
direction of the Board.

     The number of directors which shall constitute the Board (i) shall be 
not less than three nor more than nine, and (ii) shall be determined by 
resolution adopted either (A) by a vote of not less than two-thirds (2/3) of 
the members of the Board then serving, or (B) at an annual or special meeting 
of the shareholders of the Corporation by the affirmative vote of the holders 
of not less than two-thirds (2/3) of the outstanding stock entitled to vote 
for the election of directors.  No reduction in the number of directors shall 
have the effect of removing any director prior to the expiration of such 
director's term.


                                       -5-

<PAGE>

     The directors shall be divided into three classes, designated Class I, 
Class II and Class III.  Each class shall consist, as nearly as may be 
possible, of one-third of the total number of directors constituting the 
entire Board. The term of the initial Class I directors shall terminate on 
the date of the 1999 annual meeting of the shareholders of the Corporation 
(the "Annual Meeting"), the term of the initial Class II directors shall 
terminate on the date of the 2000 Annual Meeting, and the term of the initial 
Class III directors shall terminate on the date of the 2001 Annual Meeting.  
At each Annual Meeting beginning in 1999, successors to the class of 
directors whose term expires at that Annual Meeting shall be elected for a 
three-year term.  If the number of directors is changed, any increase or 
decrease shall be apportioned by the Board among the classes so as to 
maintain the number of directors in each class as nearly equal as possible, 
and any additional directors of any class elected to fill a vacancy resulting 
from an increase in such class shall hold office for a term that shall 
coincide with the remaining term of that class.  A director shall hold office 
until the Annual Meeting for the year in which such director's term expires 
and until such director's successor shall be elected and shall qualify, 
subject, however, to prior death, resignation, retirement, disqualification 
or removal from office.  Any vacancy on the Board, however, may be filled by 
a majority of the directors then in office, even if less than a quorum, or by 
the sole remaining director.

     Election of directors need not be by written ballot unless otherwise 
provided in the Bylaws.

     EIGHTH.  The Corporation shall indemnify the following persons in the 
following manner:

          (a)  The Corporation shall 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, proceeding or investigation, whether civil, criminal 
or administrative, and whether external or internal to the Corporation (other 
than a judicial action or suit brought by or in the right of the 
Corporation), by reason of the fact that such person is or was a director, 
officer, employee, trustee or agent of the Corporation, or is or was serving 
at the request of the Corporation as a director, officer,  employee, trustee 
or agent of another corporation, partnership, joint venture, trust or other 
enterprise (all such persons being referred to hereafter as an "Agent"), 
against expenses (including attorneys' fees), judgments, fines and amounts 
paid in settlement actually and reasonably incurred by the Agent in 
connection with such action, suit or proceeding if the Agent acted in good 
faith and in a manner the Agent reasonably believed to be in or not opposed 
to the best interests of the Corporation, and with respect to any criminal 
action or proceeding, had no reasonable cause to believe the Agent's conduct 
was unlawful.  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 (i) the Agent did 
not act in good faith and in a manner which the Agent reasonably believed to 
be in or not opposed to the best interests of the Corporation, or (ii) with 
respect to any criminal action or proceeding, that the Agent had reasonable 
cause to believe that the Agent's conduct was unlawful.

          (b)  The Corporation shall indemnify any person who was or is a 
party or is threatened to be made a party to any threatened, pending or 
completed judicial action or suit 


                                       -6-

<PAGE>

brought by or in the right of the Corporation to procure a judgment in its 
favor by reason of the fact that such person is or was an Agent (as defined 
above) against expenses (including attorneys' fees), actually and reasonably 
incurred by the Agent in connection with the defense or settlement of such 
action or suit if the Agent acted in good faith and in a manner the Agent 
reasonably believed to be in or not opposed to the best interests of the 
Corporation, except that no indemnification shall be made in respect of any 
claim, issue or matter as to which the Agent shall have been adjudged to be 
liable for gross negligence or misconduct in the performance of the Agent's 
duty to the Corporation, unless and only to the extent that a District Court 
of Oklahoma, 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, the Agent is fairly and reasonably 
entitled to indemnity for such expenses which a District Court of Oklahoma or 
other such court shall deem proper.

          (c)  Any indemnification under Subsection (a) or (b) of this 
Section (unless ordered by a court) shall be made by the Corporation unless a 
determination is reasonably and promptly made (i) by the Board 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, if a quorum of disinterested directors so directs, by independent 
legal counsel in a written opinion, or (iii) by the stockholders, that either 
(y) the Agent did not act in good faith and in a manner which the Agent 
reasonably believed to be in or not opposed to the best interests of the 
Corporation, or (z) with respect to any criminal action or proceeding, that 
the Agent had reasonable cause to believe that the Agent's conduct was 
unlawful.

          (d)  Notwithstanding the other provisions of this Section, to the 
extent that an Agent has been successful on the merits or otherwise, 
including the dismissal of an action without prejudice or the settlement of 
an action without admission of liability, in defense of any proceeding or in 
defense of any claim, issue or matter therein, such Agent shall be 
indemnified against all expenses incurred in connection therewith.

          (e)  Except as limited by this Subsection (e), expenses incurred in 
any action, suit, proceeding or investigation shall be paid by the 
Corporation in advance of the final disposition of such matter, if the Agent 
shall undertake to repay such amount in the event that it is ultimately 
determined, as provided herein, that the Agent is not entitled to 
indemnification.  Notwithstanding the foregoing, no advance shall be made by 
the Corporation if a determination is reasonably and promptly made by the 
Board by a majority vote of a quorum of disinterested directors, or (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, that, based upon the facts known to the Board or counsel at the time 
such determination is made, the Agent acted in bad faith and in a manner that 
the Agent did not believe to be in or not opposed to the best interest of the 
Corporation, or, with respect to any criminal proceeding, that Agent believed 
or had reasonable cause to believe the Agent's conduct was unlawful.  In no 
event shall any advance be made in instances where the Board or independent 
legal counsel reasonably determines that the Agent deliberately breached the 
Agent's duty to the Corporation or its shareholders.

          (f)  Any indemnification or advance under Subsections (a), (b), 
(c), (d) or (e) of 


                                       -7-

<PAGE>

this Section shall be made promptly, and in any event within ninety (90) 
days, upon the written request of the Agent, unless with respect to 
applications under Subsections (a), (b), (c) or (e) of this Section, a 
determination is reasonably and promptly made by the Board by a majority vote 
of a quorum of disinterested directors that such Agent acted in a manner set 
forth in such Subsections as to justify the Corporation in not indemnifying 
or making an advance to the Agent.  In the event no quorum of disinterested 
directors is obtainable, the Board shall promptly direct that independent 
legal counsel shall decide whether the Agent acted in the manner set forth in 
such Subsections as to justify the Corporation not indemnifying or making an 
advance to the Agent.  The right to indemnification or advances as granted by 
this Section shall be enforceable by the Agent in any court of competent 
jurisdiction, if the Board or independent legal counsel denies the claim, in 
whole or in part, or if no disposition of such claim is made within ninety 
(90) days.  The Agent's expenses incurred in connection with successfully 
establishing the Agent's right to indemnification, in whole or in part, in 
any such proceeding shall also be indemnified by the Corporation.

          (g)  The indemnification provided by this Section shall not be 
deemed exclusive of any other rights to which an Agent seeking 
indemnification may be entitled under any Bylaws, agreement, vote of 
stockholders or disinterested directors or otherwise, both as to action in 
the Agent's official capacity and as to action in another capacity while 
holding such office, and shall continue as to a person who has ceased to be 
an Agent and shall inure to the benefit of the heirs, executors and 
administrators of such a person.  All rights to indemnification under this 
Section shall be deemed to be provided by a contract between the Corporation 
and the Agent who serves in such capacity at any time while this Amended and 
Restated Certificate of Incorporation and the relevant provisions of the Act 
and other applicable law, if any, are in effect.  Any repeal or modification 
thereof shall not affect any rights or obligations then existing.

          (h)  Upon resolution passed by the Board, the Corporation may 
purchase and maintain insurance on behalf of any person who is or was an 
Agent against any liability asserted against such Agent and incurred by such 
Agent in any such capacity, or arising out of the Agent's status as such, 
whether or not the Corporation would have the power to indemnify the Agent 
against such liability under the provisions of this Section.

          (i)  For the purposes of this Section, references to "the 
Corporation" include all constituent corporations absorbed in a consolidation 
or merger as well as the resulting or surviving corporation, so that any 
person who is or was a director, officer, employee, trustee or agent of such 
a constituent corporation or is or was serving at the request of such 
constituent corporation as a director, officer, employee, trustee or agent of 
another corporation, partnership, joint venture, trust or other enterprise 
shall stand in the same position under the provisions of this Section with 
respect to the resulting or surviving corporation as such person would if 
such person had served the resulting or surviving corporation in the same 
capacity.

          (j)  For purposes of this Section, references to "other 
enterprises" shall include employee benefit plans; references to "fines" 
shall include any excise taxes assessed on a person with respect to any 
employee benefit plan; and references to "serving at the request of the 
Corporation" shall include any service as a director, officer, employee, 
trustee or agent of the 


                                       -8-

<PAGE>

Corporation which imposes duties on, or involves services by, such director, 
officer, employee, trustee or agent with respect to any employee benefit 
plan, its participants, or beneficiaries; and a person who acted in good 
faith and in a manner such person reasonable believed to be in the interest 
of the participants and beneficiaries of an employee benefit plan shall be 
deemed to have acted in a manner "not opposed to the best interests of the 
Corporation" as referred to in this Section.

          (k)  If this Section or any portion thereof shall be invalidated on 
any ground by any court of competent jurisdiction, then the Corporation shall 
nevertheless indemnify each Agent as to expenses (including attorneys' fees), 
judgments, fines and amounts paid in settlement with respect to any action, 
suit, proceeding or investigation, whether civil, criminal or administrative, 
and whether internal or external, including a grand jury proceeding and an 
action or suit brought by or in the right of the Corporation, to the full 
extent permitted by any applicable portion of this Section that shall not 
have been invalidated, or by any other applicable agreement or law.

     NINTH.  In furtherance and not in limitation of the powers conferred by 
statute, the Board is expressly authorized to make, repeal, alter, amend and 
rescind the Bylaws of the Corporation as set forth in the Bylaws.

     TENTH.  Whenever a compromise or arrangement is proposed between this 
Corporation and its creditors or any class of them and/or between this 
Corporation and its stockholders or any class of them, any court of equitable 
jurisdiction within the State of Oklahoma may, on the application in a 
summary way of this Corporation or of any creditor or stockholder thereof or 
on the application of any receiver or receivers appointed for this 
Corporation under the provisions of Section 1106 of Title 18 of the Act, or 
on the application of trustees in dissolution or of any receiver or receivers 
appointed for this Corporation under the provisions of Section 1100 of Title 18 
of the Act, order a meeting of the creditors or class of creditors, and/or of 
the stockholders or class of stockholders of this Corporation, as the case 
may be, to be summoned in such manner as the said court directs.  If a 
majority in number representing three-fourths in value of the creditors or 
class of creditors, and/or of the stockholders or class of stockholders of 
this Corporation, as the case may be, agree to any compromise or arrangement 
and to any reorganization of this Corporation as a consequence of such 
compromise or arrangement, the said compromise or arrangement and the said 
reorganization shall, if sanctioned by the court to which the said 
application has been made, be binding on all the creditors or class of 
creditors, and/or on all the stockholders or class of stockholders, of this 
Corporation, as the case may be, and also on this Corporation.

     ELEVENTH.  The Corporation reserves, subject to the provisions of the 
Act or any other applicable statute, the right to amend, alter, change or 
repeal any provision contained in this Amended and Restated Certificate of 
Incorporation in the manner now or hereafter prescribed by statute, and all 
rights conferred upon shareholders herein are granted subject to this 
reservation.  Notwithstanding anything contained in this Amended and Restated 
Certificate of Incorporation to the contrary, the affirmative vote of the 
holders of at least sixty-six and two-thirds percent (66 2/3%) of the issued 
and outstanding stock of this Corporation having voting power, voting 
together as a single class, shall be required to amend, repeal or adopt any 
provisions inconsistent with

Notice of any meeting of Shareholders shall not be required to be given to any
Shareholder who shall have waived such notice and such notice shall be deemed
waived by any Shareholder who shall attend such meeting in person or by proxy,
except any Shareholder who shall attend such meeting for the express purpose of
objecting, at the beginning of the meeting, to the transaction of any business
because the meeting is not lawfully called or convened.  Except as otherwise
expressly required by law, notice of any adjourned meeting of the Shareholders
need not be given if the time and place thereof are announced at the meeting at
which the adjournment is taken.

     SECTION 2.05   QUORUM.  Except in the case of any meeting for the election
of Directors summarily ordered as provided by law, the holders of record of a
majority in voting interest of the shares of stock of the Corporation entitled
to be voted thereat, present in person or by proxy, shall constitute a quorum
for the transaction of business at any meeting of the Shareholders of the
Corporation or any adjournment thereof.  In the absence of a quorum at any
meeting or any adjournment thereof, a majority in voting interest of the
Shareholders present in person or by proxy and entitled to vote thereat or, in
the absence thereof, any officer entitled to preside at, or to act as secretary
of, such meeting may adjourn such meeting from time to time.  At any such
adjourned meeting at which a quorum is present any business may be transacted
which might have been transacted at the meeting as originally called.

     (a)  Each Shareholder shall, at each meeting of the Shareholders, be
entitled to vote in person or by proxy each share or fractional share of the

which shall have been held by such Shareholder and registered in such
Shareholder's name on the books of the Corporation:

          (i)  On the date fixed pursuant to Section 6.05 of these Bylaws as the
record date for the determination of Shareholders entitled to notice of and to

meeting shall be given or (B) if notice of the meeting shall be waived, at the
close of business on the day next preceding the day on which the meeting shall

     (b)  Shares of its own stock belonging to the Corporation, or to another
corporation if a majority of the shares entitled to vote for the election of
Directors in such other corporation is held, directly or indirectly, by the
Corporation, shall neither be entitled to vote nor be counted for quorum
purposes.  Persons holding stock of the Corporation in a fiduciary capacity
shall be entitled to vote such stock.  Persons whose stock is pledged shall be
entitled to vote, unless in the transfer by the pledgor on the books of the
Corporation the pledgor shall have expressly empowered the pledgee to vote
thereon, in which case only the pledgee, or the pledgee's proxy, may represent
such stock and vote thereon.  Stock having voting power standing of record in
the names of two or more persons, whether fiduciaries, members of a partnership,
joint tenants, tenants in common, tenants by entirety or otherwise, or with
respect to which two or more persons have the same fiduciary relationship, shall
be voted in accordance with the provisions of the Oklahoma General Corporation
Act.

     (c)  Any such voting rights may be exercised by the Shareholder entitled
thereto in person or by such Shareholder's proxy appointed by an instrument in
writing, subscribed by such Shareholder or by such Shareholder's attorney
thereunto authorized and delivered to the secretary of the meeting; provided,
however, that no proxy shall be voted or acted upon after three years from its
date unless said proxy shall provide for a longer period.  The attendance at any
meeting of a Shareholder who may theretofore have given a proxy shall not have
the effect of revoking the same unless such Shareholder shall in writing so
notify the secretary of the meeting prior to the voting of the proxy.  At any
meeting of the Shareholders all matters, except as otherwise provided in the
Certificate of Incorporation, in these Bylaws or by law, shall be decided by the
vote of a majority in voting interest of the Shareholders present in person or
by proxy and entitled to vote thereat and thereon, a quorum being present.  All
elections of Directors shall be decided by a plurality.  The vote at any meeting
of the Shareholders on any question need not be by ballot, unless so directed by
the chairman of the meeting.  On a vote by ballot each ballot shall be signed by
the Shareholder voting, or by such Shareholder's proxy, if there be such proxy,
and it shall state the number of shares voted.

     SECTION 2.07   LIST OF SHAREHOLDERS.  The Secretary of the Corporation 
shall prepare and make, at least ten (10) days before every meeting of 
Shareholders, a complete list of the Shareholders entitled to vote at the 
meeting, arranged in alphabetical order, and showing the address of each 
Shareholder and the number of shares registered in the name of each 
Shareholder. Such list shall be open to the examination of any Shareholder, 
for any purpose germane to the meeting, during ordinary business hours, for a 
period of at least ten (10) days prior to the meeting, either at a place 
within the city where the meeting is to be held, which place shall be 
specified in the notice of the meeting, or, if not so specified, at the place 
where the meeting is to be held. The list shall also be produced and kept at 
the time and place of the meeting during the whole time thereof, and may be 
inspected by any Shareholder who is present.

     SECTION 2.08   JUDGES.  If at any meeting of the Shareholders a vote by
written ballot shall be taken on any question, the chairman of such meeting may
appoint a judge or 

                                      -3-

<PAGE>

judges to act with respect to such vote.  Each judge so appointed shall first 
subscribe an oath faithfully to execute the duties of a judge at such meeting 
with strict impartiality and according to the best of his ability.  Such 
judges shall decide upon the qualification of the voters and shall report the 
number of shares represented at the meeting and entitled to vote on such 
question, shall conduct and accept the votes, and, when the voting is 
completed, shall ascertain and report the number of shares voted respectively 
for and against the question.  Reports of judges shall be in writing and 
subscribed and delivered by them to the Secretary of the Corporation.  The 
judges need not be Shareholders of the Corporation, and any officer of the 
Corporation may be a judge on any question other than a vote for or against a 
proposal in which such judge shall have a material interest.

     SECTION 2.09   ACTION WITHOUT MEETING.  Any action required to be taken or
which may be taken at any annual or special meeting of Shareholders of the
Corporation may be taken without a meeting, without prior notice and without a
vote, if a consent in writing, setting forth the action so taken, shall be
signed by the holders of outstanding stock having not less than the minimum
number of votes that would be necessary to authorize or take such action at a
meeting at which all shares entitled to vote thereon were present and voted. 
Prompt notice of the taking of action without a meeting by less than unanimous
written consent shall be given to those Shareholders who have not consented in
writing.

which they shall be issued and shall be signed in the name of the Corporation by
the President or a Vice President, and by the Secretary or an Assistant
Secretary or by the Treasurer or an Assistant Treasurer.  Any of or all of the
signatures on the certificates may be a facsimile.  In case any officer,
transfer agent or registrar who has signed, or whose facsimile signature has
been placed upon, any such certificate, shall have ceased to be such officer,
transfer agent or registrar before such certificate is issued, such certificate
may nevertheless be issued by the Corporation with the same effect as though the
person who signed such certificate, or whose facsimile signature shall have been
placed thereupon, were such officer, transfer agent or registrar at the date of
issue.  A record shall be kept of the respective names of the persons, firms or
corporations owning the stock represented by such certificates, the number and
class of shares represented by such certificates, respectively, and the
respective dates thereof, and in case of cancellation, the respective dates of
cancellation.  Every certificate surrendered to the Corporation for exchange or

Corporation shall be made only on the books of the Corporation by the registered

duly executed and filed with the Secretary, or with a transfer clerk or a
transfer agent appointed as provided in Section 6.03, and upon 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 Corporation shall be deemed the owner thereof for all purposes as regards
the Corporation.  Whenever any transfer of shares shall be made for collateral
security, and not absolutely, such fact shall be so expressed in the entry of
transfer if, when the certificate or certificates shall be presented to the
Corporation for transfer, both the transferor and the transferee request the
Corporation to do so.

     SECTION 6.03   REGULATIONS.  The Board may make such rules and regulations
as it may deem expedient, not inconsistent with these Bylaws, concerning the
issue, transfer and registration of certificates for shares of the stock of the

appoint, one or more transfer clerks or one or more transfer agents and one or
more registrars, and may require all certificates for stock to bear the

rights, or entitled to exercise any rights in respect of any other change,
conversion or exchange of stock or for the purpose of any other lawful action,
the Board may fix, in advance, a record date, which shall not be more than sixty
(60) nor less than ten (10) days before the date of such meeting, nor more than
sixty (60) days nor less than ten (10) days prior to any other action.  If no
record date is fixed by the Board, the record date for determining shareholders
entitled to notice of or to vote at a meeting of shareholders shall be at the
close of business on the day next preceding the day on which notice is given,
or, if notice is waived, at the close of business on the day next preceding the
day on which the meeting is held.  A determination of Shareholders entitled to
notice of or to vote at a meeting of Shareholders shall apply to any adjournment
of such meeting; provided, however, that the Board may fix a new record date for
the adjourned meeting.

entitled to dividends, and only registered shareholders on the date so fixed

     2.   COMMITMENTS OF THE BANK.

          (a)       TERMS OF REVOLVING COMMITMENT.  On the terms and conditions
     hereinafter set forth, each Bank agrees severally to make Advances to
     the Borrowers from time to time during the period beginning on the
     Effective Date and ending on the Revolving Maturity Date in such
     amounts as the Borrowers may request up to an amount not to exceed, in
     the aggregate principal amount outstanding at any time, the Revolving
     Commitment.  The obligation of the Borrowers hereunder shall be
     evidenced by this Agreement and the Revolving Notes issued in
     connection herewith, said Revolving Notes to be as described in
     Section 3 hereof.  Notwithstanding any other provision of this
     Agreement, no Advance shall be required to be made hereunder if any
     Event of Default (as hereinafter defined) has occurred and is
     continuing or if any event or condition has occurred or failed to
     occur which with the passage of time or service of notice, or both,
     would constitute an Event of Default.  Each Advance under the
     Revolving Commitment shall be an aggregate amount of at least $100,000
     or a whole number multiple thereof except an Advance of the entire
     remaining unborrowed Revolving Commitment.  Irrespective of the face
     amount of the Revolving Note or Notes, the Banks shall never have the
     obligation to Advance any amount or amounts in excess of the Revolving
     Commitment or to increase the Revolving Commitment.  The total number
     of Tranches under the Revolving Commitment which may be outstanding at
     any time hereunder shall never exceed five (5), whether such Tranches
     are Prime Rate Loans, LIBOR Loans, or a combination thereof.  Within
     the limit of each Bank's Revolving Commitment, the Borrowers may
     borrow, repay and reborrow under this Section 2 prior to the Revolving
     Maturity Date.

                                     -13-
<PAGE>

          (b)    PROCEDURE FOR BORROWING.  Whenever the Borrowers desire an
     Advance hereunder, they shall give Agent telegraphic, telex, facsimile
     or telephonic notice ("Notice of Borrowing") of such requested
     Advance, which in the case of telephonic notice, shall be promptly
     confirmed in writing.  Each Notice of Borrowing shall be in the form
     of Exhibit "A" attached hereto and shall be received by Agent not
     later than 11:00 a.m. Oklahoma City, Oklahoma time, (i) one Business
     Day prior to the Borrowing Date in the case of the Prime Rate Loan, or
     (ii) two London Business Days prior to any proposed Borrowing Date in
     the case of LIBOR Loans.  Each Notice of Borrowing shall specify
     (i) the Borrowing Date (which, if at Prime Rate Loan, shall be a
     Business Day and if a LIBOR Loan, a London Business Day), (ii) the
     principal amount to be borrowed, (iii) the portion of the Advance
     constituting Prime Rate Loans and/or LIBOR Loans and (iv) if any
     portion of the proposed Advance is to constitute LIBOR Loans, the
     initial Interest Period selected by Borrowers pursuant to Section 4
     hereof to be applicable thereto.  Upon receipt of such Notice, Agent
     shall advise each Bank thereof; provided, that if the Banks have
     received at least one (1) day's notice of such Advance prior to
     funding of a Prime Rate Loan, or at least two (2) days' notice of each
     Advance prior to funding in the case of a LIBOR Loan, each Bank shall
     provide Agent at its office at 100 North Broadway, Oklahoma City,
     Oklahoma 73125, not later than 1:00 p.m.,Oklahoma City, Oklahoma time,
     on the Borrowing Date, in immediately available funds, its pro rata
     share of the requested Advance, but the aggregate of all such fundings
     by each Bank shall never exceed such Bank's Revolving Commitment.  Not
     later than 2:00 p.m., Oklahoma City, Oklahoma time, on the Borrowing
     Date, Agent shall make available to the Borrowers at the same office,
     in like funds, the aggregate amount of such requested Advance. 
     Neither Agent nor any Bank shall incur any liability to the Borrowers
     in acting upon any Notice of Borrowing which Agent or such Bank
     believes in good faith to have been given by a duly authorized officer
     or other person authorized to borrow on behalf of Borrowers or for
     otherwise acting in good faith under this Section 2(b).  Upon funding
     of Advances by Banks in accordance with this Agreement, pursuant to
     any such Notice, the Borrowers shall have effected Advances hereunder.

          (c)    LETTERS OF CREDIT.  On the terms and conditions hereinafter
     set forth, the Agent shall from time to time during the period
     beginning on the Effective Date and ending on the Revolving Maturity
     Date upon request of Borrowers issue standby and/or commercial Letters
     of Credit for the account of Borrowers (the "Letters of Credit") in
     such face amounts as Borrowers may request, but not to exceed in the
     aggregate face amount at any time outstanding the sum of Ten Million
     Dollars ($10,000,000.00).  The face amount of all Letters of Credit
     issued and outstanding hereunder shall be considered as Advances for
     Borrowing Base purposes and all payments made by the Agent on such
     Letters of Credit shall be considered as Advances under the Revolving
     Notes.  Each Letter of Credit issued 


                                    -14-

<PAGE>

     for the account of Borrowers hereunder shall (i) be in favor of such 
     beneficiaries as specifically requested by Borrowers, (ii) have an 
     expiration date not exceeding the earlier of (a) one year or (b) the 
     Revolving Maturity Date, and (iii) contain such other terms and 
     provisions as may be reasonably required by Bank.  Each Bank (other than 
     Agent) agrees that, upon issuance of any Letter of Credit hereunder, it 
     shall automatically acquire a participation in the Agent's liability 
     under such Letter of Credit in an amount equal to such Bank's Revolving 
     Commitment Percentage of such liability, and each Bank (other than 
     Agent) thereby shall absolutely, unconditionally and irrevocably assume, 
     as primary obligor and not as surety, and shall be unconditionally 
     obligated to Agent to pay and discharge when due, its Revolving 
     Commitment Percentage of Agent's liability under such Letter of Credit.  
     The Borrowers hereby unconditionally agree to pay and reimburse the 
     Agent for the amount of each demand for payment under any Letter of 
     Credit that is in substantial compliance with the provisions of any such 
     Letter of Credit at or prior to the date on which payment is to be made 
     by the Agent to the beneficiary thereunder, without presentment, demand, 
     protest or other formalities of any kind.  Upon receipt from any 
     beneficiary of any Letter of Credit of any demand for payment under such 
     Letter of Credit, the Agent shall promptly notify the Borrowers of the 
     demand and the date upon which such payment is to be made by the Agent 
     to such beneficiary in respect of such demand. Forthwith upon receipt of 
     such notice from the Agent, Borrowers shall advise the Agent whether or 
     not they intend to borrow hereunder to finance their obligations to 
     reimburse the Agent, and if so, submit a Notice of Borrowing as provided 
     in Section 2(b) hereof.  If Borrowers fail to so advise Agent and 
     thereafter fail to reimburse Agent, the Agent shall notify each Bank of 
     the demand and the failure of the Borrowers to reimburse the Agent, and 
     each Bank shall reimburse the Agent for its Revolving Commitment 
     Percentage of each such draw paid by the Agent and unreimbursed by the 
     Borrowers.  All such amounts paid by Agent and/or reimbursed by the 
     Banks shall be treated as an Advance or Advances under the Revolving 
     Commitment, which Advances shall be immediately due and payable and 
     shall bear interest at the Default Rate.

          (d)    PROCEDURE FOR OBTAINING LETTERS OF CREDIT.  The amount and
     date of issuance, renewal, extension or reissuance of a Letter of
     Credit pursuant to the Banks' commitment above in Section 2(c) shall
     be designated by Borrowers' written request delivered to Agent at
     least three (3) Business Days prior to the date of such issuance,
     renewal, extension or reissuance.  Concurrently with or promptly
     following the delivery of the request for a Letter of Credit,
     Borrowers shall execute and deliver to the Agent an application and
     agreement with respect to the Letters of Credit, said application and
     agreement to be in the form used by the Agent.  The Agent shall not be
     obligated to issue, renew, extend or reissue such Letters of Credit if
     (A) the amount thereon when added to the face amount of all
     outstanding Letters of Credit plus any Reimbursement Obligations
     exceeds Ten Million Dollars ($10,000,000.00) or (B) the amount thereof
     when added to the Total Outstandings 


                                    -15-

<PAGE>

     would exceed the Revolving Commitment.  Borrowers agree to pay the Agent 
     for the benefit of the Banks commissions for issuing the Letters of 
     Credit (calculated separately for each Letter of Credit) in an amount 
     equal to the greater of (i) one percent (1%) per annum on the maximum 
     face amount of the Letter of Credit or (ii) $500.00.  Borrowers further 
     agree to pay Agent an additional fronting fee equal to one-eighth of one 
     percent (.125%) per annum on the maximum face amount of each Letter of 
     Credit.  Such commissions shall be payable prior to the issuance of each 
     Letter of Credit and thereafter on each anniversary date of such 
     issuance while such Letter of Credit is outstanding.

          (e)    VOLUNTARY REDUCTION OF REVOLVING COMMITMENT.  The Borrowers
     may at any time, or from time to time, upon not less than three (3)
     Business Days' prior written notice to Agent, reduce or terminate the
     Revolving Commitment; provided, however, that (i) each reduction in
     the Revolving Commitment must be in the amount of $500,000 or more, in
     increments of $100,000 and (ii) each reduction must be accompanied by
     a prepayment of the Revolving Notes in the amount by which the
     outstanding principal balance of the Revolving Notes exceeds the
     Revolving Commitment as reduced pursuant to this Section 2.

          (f)    MANDATORY COMMITMENT REDUCTIONS -

                 (i)   MONTHLY COMMITMENT REDUCTION.  The Borrowing Base and
          the Revolving Commitment shall be reduced as of the first day of
          each month by an amount determined by the Banks pursuant to
          Section 7(b) hereof (the "Monthly Commitment Reduction").  The
          Monthly Commitment Reduction shall be $0 beginning on June 1,
          1998, with like reductions continuing on the first day of each
          month thereafter until redetermined pursuant to Section 7(b)
          hereof.  If as a result of any such Monthly Commitment Reduction,
          the Total Outstandings ever exceed the Revolving Commitment then
          in effect, the Borrowers shall make the mandatory prepayment of
          principal required pursuant to Section 9(b) hereof.

                 (ii)  OTHER REDUCTIONS.  The Borrowing Base shall be reduced
          from time to time by the amount of any prepayment required by
          Section 12(r) hereof upon the sale of Oil and Gas Properties. 
          If, as a result of any such reduction in the Borrowing Base, the
          Total Outstandings ever exceed the Borrowing Base then in effect,
          the Borrowers shall make the mandatory prepayment of principal
          required pursuant to Section 9(b) hereof.

          (g)    SEVERAL OBLIGATIONS.  The obligations of the Banks under the
     Revolving Commitment are several and not joint.  The failure of any
     Bank to make an Advance required to be made by it shall not relieve
     any other Bank of its obligation to make its Advance, and no Bank
     shall be responsible for the failure of 


                                    -16-

<PAGE>

     any other Bank to make the Advance to be made by such other Bank.

     2.   NOTES EVIDENCING LOANS.  The loans described above in Section 2
shall be evidenced by promissory notes of Borrowers as follows:

          (a)    FORM OF REVOLVING NOTES - The Revolving Loan shall be
     evidenced by a Note or Notes in the aggregate face amount of
     $175,000,000, and shall be in the form of Exhibit "B" hereto with
     appropriate insertions (each a "Revolving Note").  Notwithstanding the
     face amount of the Revolving Notes, the actual principal amount due
     from the Borrowers to Banks on account of the Revolving Notes, as of
     any date of computation, shall be the sum of Advances then and
     theretofore made on account thereof, less all principal payments
     actually received by Banks in collected funds with respect thereto. 
     Although the Revolving Notes may be dated as of the Effective Date,
     interest in respect thereof shall be payable only for the period
     during which the loans evidenced thereby are outstanding and, although
     the stated amount of the Revolving Notes may be higher, the Revolving
     Notes shall be enforceable, with respect to Borrowers' obligation to
     pay the principal amount thereof, only to the extent of the unpaid
     principal amount of the loans.  Irrespective of the face amount of the
     Revolving Notes, no Bank shall ever be obligated to advance on the
     Revolving Commitment any amount in excess of its Revolving Commitment
     then in effect.

          (b)    ISSUANCE OF ADDITIONAL NOTES - At the Effective Date there
     shall be outstanding one Revolving Note in the aggregate face amount
     of $175,000,000 payable to the order of Bank One-Oklahoma.  From time
     to time new Notes may be issued to other Banks as such Banks become
     parties to this Agreement.  Upon request from Agent, the Borrowers
     shall execute and deliver to Agent any such new or additional Notes. 
     From time to time as new Notes are issued the Agent shall require that
     each Bank exchange their Notes for newly issued Notes to better
     reflect the extent of each Bank's Revolving Commitment hereunder.  The
     notes replaced shall be marked to indicate that they have been
     replaced and/or returned to the Borrowers.

          (c)    INTEREST RATES - The unpaid principal balance of the Notes
     shall bear interest from time to time as set forth in Section 4
     hereof.

          (d)    PAYMENT OF INTEREST - Interest on the Notes shall be payable
     on each Interest Payment Date.

          (e)    PAYMENT OF PRINCIPAL - Principal of the Revolving Note or
     Notes shall be due and payable to the Agent for the ratable benefit of
     the Banks on the Revolving Maturity Date unless earlier due in whole
     or in part as a result of an acceleration of the amount due or
     pursuant to the mandatory prepayment provisions


                                    -17-

<PAGE>

     of Section 9(b) hereof.

          (f)    PAYMENT TO BANKS - Each Bank's Pro Rata Part of each payment
     or prepayment of the Loans shall be directed by wire transfer to such
     Bank by the Agent at the address provided to the Agent for such Bank
     for payments no later than 2:00 p.m., Oklahoma City, Oklahoma, time on
     the Business Day such payments or prepayments are deemed hereunder to
     have been received by Agent; provided, however, in the event that any
     Bank shall have failed to make an Advance as contemplated under
     Section 2 hereof (a "Defaulting Bank") and the Agent or another Bank
     or Banks shall have made such Advance, payment received by Agent for
     the account of such Defaulting Bank or Banks shall not be distributed
     to such Defaulting Bank or Banks until such Advance or Advances shall
     have been repaid in full to the Bank or Banks who funded such Advance
     or Advances.  Any payment or prepayment received by Agent at any time
     after 12:00 noon, Oklahoma City, Oklahoma, time on a Business Day
     shall be deemed to have been received on the next Business Day. 
     Interest shall cease to accrue on any principal as of the end of the
     day preceding the Business Day on which any such payment or prepayment
     is deemed hereunder to have been received by Agent.  If Agent fails to
     transfer any principal amount to any Bank as provided above, then
     Agent shall promptly direct such principal amount by wire transfer to
     such Bank.

          (g)    SHARING OF PAYMENTS, ETC. - If any Bank shall obtain any
     payment (whether voluntary, involuntary, or otherwise) on account of
     the Loans, (including, without limitation, any set-off) which is in
     excess of its Pro Rata Part of payments on either of the Loans, as the
     case may be, obtained by all Banks, such Bank shall purchase from the
     other Banks such participation as shall be necessary to cause such
     purchasing Bank to share the excess payment pro rata with each of
     them; provided that, if all or any portion of such excess payment is
     thereafter recovered from such purchasing Bank, the purchase shall be
     rescinded and the purchase price restored to the extent of the
     recovery.  The Borrowers agree that any Bank so purchasing a
     participation from another Bank pursuant to this Section may, to the
     fullest extent permitted by law, exercise all of its rights of payment
     (including the right of offset) with respect to such participation as
     fully as if such Bank were the direct creditor of the Borrowers in the
     amount of such participation.

          (h)    NON-RECEIPT OF FUNDS BY THE AGENT - Unless the Agent shall
     have been notified by a Bank or the Borrowers (the "Payor") prior to
     the date on which such Bank is to make payment to the Agent of the
     proceeds of a Loan to be made by it hereunder or the Borrowers are to
     make a payment to the Agent for the account of one or more of the
     Banks, as the case may be (such payment being herein called the
     "Required Payment"), which notice shall be effective upon receipt,
     that the Payor does not intend to make the Required Payment to the
     Agent, the Agent may assume that the Required Payment has been made
     and may, in reliance upon such 


                                    -18-

<PAGE>

     assumption (but shall not be required to), make the amount thereof 
     available to the intended recipient on such date and, if the Payor has 
     not in fact made the Required Payment to the Agent, the recipient of 
     such payment shall, on demand, pay to the Agent the amount made 
     available to it together with interest thereon in respect of the period 
     commencing on the date such amount was made available by the Agent until 
     the date the Agent recovers such amount at the rate applicable to such 
     portion of the applicable Loan.

          (i)    CAPITAL ADEQUACY - If either (i) the introduction or
     implementation of or the compliance with or any change in or in the
     interpretation of any law, rule or regulation or (ii) the introduction
     or implementation of or the compliance with any mandatory request,
     directive or guideline from any central bank or other governmental
     authority (whether or not having the force of law) affects or would
     affect the amount of capital required or expected to be maintained by
     any Bank or any corporation controlling any Bank as a result of
     maintaining its Pro Rata Part of the Revolving Commitment, then within
     fifteen (15) days after demand by such Bank, the Borrowers will pay to
     such Bank, from time to time as specified by such Bank, such
     additional amount or amounts which such Bank shall reasonably
     determine to be appropriate to compensate such Bank or any corporation
     controlling such Bank in light of such circumstances, to the extent
     that such Bank reasonably determines that the amount of any such
     capital would be increased, or the rate of return on any such capital
     would be reduced in whole or in part, based on the existence of the
     amount of the Loans or such Bank's Revolving Commitment under this
     Agreement; provided, however, that to the extent such notice is given
     by any such Bank more than 180 days after the occurrence of the event
     giving rise to the additional costs of the type described in this
     Section, such Bank shall not be entitled to compensation pursuant to
     this Section for any amounts incurred or accruing prior to the date
     180 days before the giving of such notice, except to the extent such
     law, rule, regulation, request, directive or guideline shall have been
     given retroactive effective affecting a period beginning more than 180
     days prior to such notice.

     4.   INTEREST RATES.

          (a)    OPTIONS.

                 (i)   PRIME RATE LOANS.  On Prime Rate Loans the Borrowers
          agree to pay interest on the Notes calculated on the basis of the
          actual days elapsed in a year consisting of 360 days with respect
          to the unpaid principal amount of each Prime Rate Loan from the
          date the proceeds thereof are advanced to Borrowers until
          maturity (whether by acceleration or otherwise), at a varying
          rate per annum equal to the lesser of (i) the Maximum Rate
          (defined herein), or (ii) the sum of the Prime Rate plus the
          Prime Rate Margin.  Subject to the provisions of this Agreement
          as to prepayment, the principal of the Notes representing Prime
          Rate Loans shall be payable as specified in Section 3(e) hereof
          and the interest in respect of each Prime Rate Loan shall be
          payable on each Interest Payment Date.  Past due principal and,
          to the extent permitted by law, past due interest in respect to
          each Prime Rate Loan, shall bear interest, payable on demand, at
          a rate per annum equal to the Default Rate.

                 (ii)  LIBOR LOANS.  On LIBOR Loans the Borrowers agree to pay
          interest calculated on the basis of a year consisting of 360 days
          with respect to the unpaid principal amount of each LIBOR Loan
          from the date the proceeds thereof are advanced to Borrowers
          until maturity (whether by acceleration or otherwise), at a
          varying rate per annum equal to the lesser of (i) the Maximum
          Rate, or (ii) the LIBOR Rate plus the LIBOR Margin.  Subject to
          the provisions of this Agreement with respect to prepayment, the
          principal of the Notes shall be payable as specified in Section
          3(e) hereof and the interest with respect to each LIBOR Loan
          shall be payable on each Interest Payment Date.  Past due
          principal and, to the extent permitted by law, past due interest
          shall bear interest, payable on demand, at a rate per annum equal
          to the Default Rate.  Upon three (3) London Business Days'
          written notice prior to the making by the Banks of any LIBOR Loan
          (in the case of the initial Interest Period therefor) or the
          expiration date of each succeeding Interest Period (in the case
          of subsequent Interest Periods therefor), Borrowers shall have
          the option, subject to compliance by Borrowers with all of the
          provisions of this Agreement, as long as no Event of Default
          exists, to specify whether the Interest Period commencing on any
          such date shall be a one (1), two (2), three (3) or six (6) month
          period.  If Agent shall not have received timely notice of a
          designation of such Interest Period as herein provided, Borrowers
          shall be deemed to have elected to convert all maturing LIBOR
          Loans to Prime Rate Loans.


                                    -20-

<PAGE>

          (b)    INTEREST RATE DETERMINATION.  The Agent shall determine each
     interest rate applicable to the Loans hereunder in accordance with the
     provisions of this Agreement.  The Agent shall give prompt notice to
     the Borrowers and the Banks of each rate of interest so determined and
     its determination thereof shall be conclusive absent error.

          (c)    CONVERSION OPTION.  Borrowers may elect from time to time
     (i) to convert all or any part of its LIBOR Loans to Prime Rate Loans
     by giving Agent irrevocable notice of such election in writing prior
     to 10:00 a.m. (Oklahoma City, Oklahoma time) on the conversion date
     and such conversion shall be made on the requested conversion date,
     provided that any such conversion of a LIBOR Loan shall only be made
     on the last day of the LIBOR Interest Period with respect thereof,
     (ii) to convert all or any part of its Prime Rate Loans to LIBOR Loans
     by giving the Agent irrevocable written notice of such election three
     (3) London Business Days prior to the proposed conversion and such
     conversion shall be made on the requested conversion date or, if such
     requested conversion date is not a London Business Day or a Business
     Day, as the case may be, on the next succeeding London Business Day or
     Business Day, as the case may be.  Any such conversion shall not be
     deemed to be a prepayment of any of the loans for purposes of this
     Agreement or the Notes.

          (d)    RECOUPMENT.  If at any time the applicable rate of interest
     selected pursuant to Sections 4(a)(i) or 4(a)(ii) above shall exceed
     the Maximum Rate, thereby causing the interest on the Notes to be
     limited to the Maximum Rate, then any subsequent reduction in the
     interest rate so selected or subsequently selected shall not reduce
     the rate of interest on the Notes below the Maximum Rate until the
     total amount of interest accrued on the Note equals the amount of
     interest which would have accrued on the Notes if the rate or rates
     selected pursuant to Sections 4(a)(i) or (ii), as the case may be, had
     at all times been in effect.

     5.   CHANGE OF CIRCUMSTANCES.

          (a)    UNAVAILABILITY OF FUNDS OR INADEQUACY OF PRICING.  In the
     event that, in connection with any proposed LIBOR Loan, the Agent
     determines, which determination shall, absent manifest error, be
     final, conclusive and binding upon all parties, due to changes in
     circumstances since the date hereof, adequate and fair means do not
     exist for determining the LIBOR Rate or such rate will not accurately
     reflect the costs to the Banks of funding LIBOR Loans for such LIBOR
     Interest Period, the Agent shall give notice of such determination to
     the Borrowers and the Banks, whereupon, until the Agent notifies the
     Borrowers and the Banks that the circumstances giving rise to such
     suspension no longer exist, the obligations of the Banks to make,
     continue or convert Loans into LIBOR Loans shall be suspended, and all
     loans to Borrowers shall be Prime Rate Loans during the period of


                                    -21-

<PAGE>

     suspension.

          (b)    CHANGE IN LAWS.  If at any time any new law or any change in
     existing laws or in the interpretation of any new or existing laws
     shall make it unlawful for any Bank to make or continue to maintain or
     fund LIBOR Loans hereunder, then such Bank shall promptly notify
     Borrowers in writing and such Bank's obligation to make, continue or
     convert Loans into LIBOR Loans under this Agreement shall be suspended
     until it is no longer unlawful for such Bank to make or maintain LIBOR
     Loans.  Upon receipt of such notice, Borrowers shall either repay the
     outstanding LIBOR Loans owed to the Banks, without penalty, on the
     last day of the current Interest Periods (or, if any Bank may not
     lawfully continue to maintain and fund such LIBOR Loans, immediately),
     or Borrowers may convert such LIBOR Loans at such appropriate time to
     Prime Rate Loans.

          (c)    INCREASED COST OR REDUCED RETURN.

                 (i)   If, after the date hereof, the adoption of any
          applicable law, rule, or regulation, or any change in any
          applicable law, rule, or regulation, or any change in the
          interpretation or administration thereof by any governmental
          authority, central bank, or comparable agency charged with the
          interpretation or administration thereof, or compliance by any
          Bank with any request or directive (whether or not having the
          force of law) of any such governmental authority, central bank,
          or comparable agency:

                       (A)  shall subject such Bank to any tax, duty, or other
                   charge with respect to any LIBOR Loans, its Notes, or its
                   obligation to make LIBOR Loans, or change the basis of
                   taxation of any amounts payable to such Bank under this
                   Agreement or its Notes in respect of any LIBOR Loans (other
                   than franchise taxes and taxes imposed on the overall net
                   income of such Bank);

                       (B)  shall impose, modify, or deem applicable any
                   reserve, special deposit, assessment, or similar requirement
                   (other than reserve requirements, if any, taken into account
                   in the determination of the LIBOR Rate) relating to any
                   extensions of credit or other assets of, or any deposits
                   with or other liabilities or commitments of, such Bank,
                   including the Revolving Commitment of such Bank hereunder;
                   or

                       (C)  shall impose on such Bank or on the London
                   interbank market any other condition affecting this
                   Agreement or its Notes or any of such extensions of credit
                   or liabilities or commitments;


                                    -22-

<PAGE>

          and the result of any of the foregoing is to increase the cost to
          such Bank of making, converting into, continuing, or maintaining
          any LIBOR Loans or to reduce any sum received or receivable by
          such Bank under this Agreement or its Notes with respect to any
          LIBOR Loans, then Borrowers shall pay to such Bank on demand
          such amount or amounts as will compensate such Bank for such
          increased cost or reduction.  If any Bank requests compensation
          by Borrowers under this Section 5(c), Borrowers may, by notice to
          such Bank (with a copy to Agent), suspend the obligation of such
          Bank to make or continue LIBOR Loans, or to convert all or part
          of the Prime Rate Loan owing to such Bank to LIBOR Loans, until
          the event or condition giving rise to such request ceases to be
          in effect (in which case the provisions of Section 5(c) shall be
          applicable); PROVIDED that such suspension shall not affect the
          right of such Bank to receive the compensation so requested.

                    (ii)  If, after the date hereof, any Bank shall have
          determined that the adoption of any applicable law, rule, or
          regulation regarding capital adequacy or any change therein or in
          the interpretation or administration thereof by any governmental
          authority, central bank, or comparable agency charged with the
          interpretation or administration thereof, or any request or
          directive regarding capital adequacy (whether or not having the
          force of law) of any such governmental authority, central bank,
          or comparable agency, has or would have the effect of reducing
          the rate of return on the capital of such Bank or any corporation
          controlling such Bank as a consequence of such Bank's obligations
          hereunder to a level below that which such Bank or such
          corporation could have achieved but for such adoption, change,
          request, or directive (taking into consideration its policies
          with respect to capital adequacy), then from time to time upon
          demand Borrowers shall pay to such Bank such additional amount or
          amounts as will compensate such Bank for such reduction.

                    (iii) Each Bank shall promptly notify Borrowers and
          Agent of any event of which it has knowledge, occurring after the
          date hereof, which will entitle such Bank to compensation
          pursuant to this Section 5(c) will designate a separate lending
          office, if applicable, if such designation will avoid the need
          for, or reduce the amount of, such compensation and will not, in
          the judgment of such Bank, be otherwise disadvantageous to it. 
          Any Bank claiming compensation under this Section 5(c) shall
          furnish to Borrowers and Agent a statement setting forth the
          additional amount or amounts to be paid to it hereunder which
          shall be conclusive in the absence of manifest error.  In
          determining such amount, such Bank may use any reasonable
          averaging and attribution methods.


                                    -23-

<PAGE>

                 (iv)  Any Bank giving notice to the Borrowers through the
          Agent, pursuant to Section 5(c) shall give to the Borrowers a
          statement signed by an officer of such Bank setting forth in
          reasonable detail the basis for, and the calculation of such
          additional cost, reduced payments or capital requirements, as the
          case may be, and the additional amounts required to compensate
          such Bank therefor.

                 (v)   Within five (5) Business Days after receipt by the
          Borrowers of any notice referred to in Section 5(c), the
          Borrowers shall pay to the Agent for the account of the Bank
          issuing such notice such additional amounts as are required to
          compensate such Bank for the increased cost, reduce payments or
          increase capital requirements identified therein, as the case may
          be; provided, that the Borrowers shall not be obligated to
          compensate such Bank for any increased costs, reduced payments or
          increased capital requirements to the extent that such Bank
          incurs the same prior to a date six (6) months before such Bank
          gives the required notice.

          (d)    DISCRETION OF BANK AS TO MANNER OF FUNDING.  Notwithstanding
     any provisions of this Agreement to the contrary, each Bank shall be
     entitled to fund and maintain its funding of all or any part of its
     Loans in any manner it sees fit, it being understood, however, that
     for the purposes of this Agreement all determinations hereunder shall
     be made as if each  Bank had actually funded and maintained each LIBOR
     Loan through the purchase of deposits having a maturity corresponding
     to the last day of the LIBOR Interest Period applicable to such LIBOR
     Loan and bearing an interest rate to the applicable interest rate for
     such LIBOR Period.

          (e)    BREAKAGE FEES.   Without duplication under any other
     provision hereof, if any Bank incurs any loss, cost or expense
     (including, without limitation, any loss of profit and loss, cost,
     expense or premium reasonably incurred by reason of the liquidation or
     re-employment of deposits or other funds acquired by such Bank to fund
     or maintain any LIBOR Loan or the relending or reinvesting of such
     deposits or amounts paid or prepaid to the Banks) as a result of any
     of the following events other than any such occurrence as a result in
     the change of circumstances described in Sections 5(a) and (b):

                 (i)   any payment, prepayment or conversion of a LIBOR Loan
          on a date other than the last day of its LIBOR Interest Period
          (whether by acceleration, prepayment or otherwise);

                 (ii)  any failure to make a principal payment of a LIBOR Loan
          on the due date thereof; or 


                                    -24-

<PAGE>

                 (iii) any failure by the Borrowers to borrow, continue,
          prepay or convert to a LIBOR Loan on the dates specified in a
          notice given pursuant to Section 2(b) or 4(c) hereof;

     then the Borrowers shall pay to such Bank such amount as will
     reimburse such Bank for such loss, cost or expense.  If any Bank makes
     such a claim for compensation, it shall furnish to Borrowers and Agent
     a statement setting forth the amount of such loss, cost or expense in
     reasonable detail (including an explanation of the basis for and the
     computation of such loss, cost or expense) and the amounts shown on
     such statement shall be conclusive and binding absent manifest error.

     6.   COLLATERAL SECURITY.

          (a)    PLEDGE OF COLLATERAL.  To secure the performance by
     Borrowers of their obligations hereunder, and under the Notes and
     Security Instruments, whether now or hereafter incurred, matured or
     unmatured, direct or contingent, joint or several, or joint and
     several, including extensions, modifications, renewals and increases
     thereof, and substitutions therefore, Borrowers have heretofore
     granted and assigned to Bank One-Oklahoma a first and prior lien on
     certain of their Oil and Gas Properties, certain related equipment,
     oil and gas inventory and the proceeds of the foregoing. 
     Contemporaneously with the execution of this Agreement and the Notes,
     the Borrowers shall grant and assign to Agent for the ratable benefit
     of the Banks a first and prior Lien on certain of its Oil and Gas
     Properties, certain related equipment, oil and gas inventory, certain
     bank accounts, the System, the Plant and proceeds of the foregoing. 
     The Liens held by Bank One-Oklahoma on the Oil and Gas Properties
     shall be assigned, as of the Effective Date, to the Agent for the
     ratable benefit of the Banks.  The Oil and Gas Properties heretofore
     and herewith mortgaged to the Agent shall represent not less than 90%
     of the Engineered Value (as hereinafter defined) of Borrowers' Oil and
     Gas Properties as of the Effective Date.  All Oil and Gas Properties
     and other collateral in which Borrowers have heretofore granted to
     Bank One-Oklahoma, or herewith grant or hereafter grant to Agent for
     the ratable benefit of the Banks a first and prior Lien (to the
     satisfaction of the Agent) in accordance with this Section 6, as such
     properties and interests are from time to time constituted, are
     hereinafter collectively called the "Collateral".

          (b)    DOCUMENTATION AND TITLE REVIEW.  The granting and assigning
     of such security interests and Liens by Borrowers shall be pursuant to
     Security Instruments in form and substance reasonably satisfactory to
     the Agent.  Concurrently with the delivery of each of the Security
     Instruments or within a reasonable time thereafter, Borrowers shall
     furnish to the Agent mortgage and title opinions and other title
     information satisfactory to Agent with respect to the title and Lien
     status of Borrowers' interests in not less than 80% of the Engineered
     Value of the Oil and Gas Properties covered by the Security
     Instruments as Agent shall 


                                    -25-

<PAGE>

     have designated.  "Engineered Value" for this purpose shall mean future 
     net revenues discounted at the discount rate being used by the Agent as 
     of the date of any such determination utilizing the pricing parameters 
     used in the engineering report furnished to the Agent for the ratable 
     benefit of the Banks, pursuant to Sections 7 and 12 hereof.  Borrowers 
     will cause to be executed and delivered to the Agent, in the future, 
     additional Security Instruments if the Agent reasonably deems such are 
     necessary to insure perfection or maintenance of Banks' security 
     interests and Liens in the Collateral or any part thereof.

          (c)    LETTERS IN LIEU OF TRANSFER ORDERS.  The Borrowers shall
     provide the Agent for the benefit of the Banks, undated letters in
     lieu of transfer orders, in form and substance satisfactory to Agent,
     from the Borrowers to each purchaser of hydrocarbons and disburser
     proceeds of hydrocarbons from and attributable to the Oil and Gas
     Properties, together with additional letters with addresses left blank
     authorizing and directing the addressees to make future payments
     attributable to hydrocarbons from the Oil and Gas Properties directly
     to the Agent for the benefit of the Banks.  The Banks agree that none
     of the letters in lieu of transfer orders provided by the Borrowers
     pursuant to this Section 6(c) will be sent to the address prior to the
     occurrence of an Event of Default, at which time the Agent may, at its
     option and in addition to the exercise of any of its other rights and
     remedies, send any and all of such letters to such addressees;
     provided, however, that upon the occurrence of an Event of Default
     other than those specified in Sections 14(f) and (g), the Agent shall
     not send any or all of such letters until the applicable period to
     cure, if any, such Default has lapsed without such Default being
     cured.  Borrowers hereby designate the Agent as its agent and
     attorney-in-fact, to act in its name, place and stead for the purpose
     of completing and delivering any and all letters in lieu of transfer
     orders delivered by the Borrowers to the Agent for the benefit of the
     Banks pursuant to Sections 6(c) and 11(a)(x) hereof, including,
     without limitation, completing any blanks contained in such letters
     and attaching exhibits thereto describing the relevant Collateral. 
     Borrowers hereby ratify and confirm all that the Agent shall lawfully
     do or cause to be done by virtue of this power of attorney and the
     rights granted with respect to such power of attorney.  This power of
     attorney is coupled with the interests of the Agent in the Collateral,
     shall commence and be in full force and effect as of the Effective
     Date and shall remain in full force and effect and shall be
     irrevocable until the obligations, if any, of the Agent hereunder have
     terminated and the full satisfaction of all obligations due hereunder
     or under the Notes.  The powers conferred on Agent by this appointment
     may only be exercised by the Agent by execution by any Person who, at
     the time of exercise, is an officer of the Agent, and are solely to
     protect the interests of the Agent and the Banks under the Loan
     Documents and shall not impose any duty upon the Agent to exercise any
     such powers.  The Agent shall be accountable only for amounts that it
     actually receives or has expressly directed that others receive as a
     result of the exercise of such powers and shall not be responsible to
     the Borrowers, or any other Person for 


                                    -26-

<PAGE>

     any act or failure to act with respect to such powers, except for gross
     negligence or willful misconduct.

     7.   BORROWING BASE.

          (a)    INITIAL BORROWING BASE. At the Effective Date, the Borrowing
     Base shall be $175,000,000.00.

          (b)    SUBSEQUENT DETERMINATIONS OF BORROWING BASE.  Subsequent
     determinations of the Borrowing Base shall be made by the Banks at
     least semi-annually on May 1 and November 1 of each year beginning
     November 1, 1998 or as Unscheduled Redeterminations.  In connection
     with, and as of, each determination of the Borrowing Base, the Banks
     shall also redetermine the Monthly Commitment Reduction.  The
     Borrowers shall furnish to the Banks as soon as possible but in any
     event no later than April 1 of each year, beginning April 1, 1999,
     with an engineering report in form and substance satisfactory to the
     Agent prepared by an independent petroleum engineering acceptable to
     Agent covering the Oil and Gas Properties utilizing economic and
     pricing parameters used by Agent as established from time to time,
     together with such other information concerning the value of the Oil
     and Gas Properties as the Agent shall deem necessary to determine the
     value of the Oil and Gas Properties.  By October 1 of each year, or
     within thirty (30) days after either (i) receipt of notice from Agent
     that the Banks require an Unscheduled Redetermination, or (ii) the
     Borrowers give notice to Agent of their desire to have an Unscheduled
     Redetermination performed, the Borrowers shall furnish to the Banks an
     engineering report in form and substance satisfactory to Agent
     prepared by Borrowers' in-house engineering staff valuing the Oil and
     Gas Properties utilizing economic and pricing parameters used by the
     Agent as established from time to time, together with such other
     information, reports and data concerning the value of the Oil and Gas
     Properties as Agent shall deem reasonably necessary to determine the
     value of such Oil and Gas Properties.  Agent shall by notice to the
     Borrowers no later than May 1 and November 1 of each year, or within a
     reasonable time thereafter (herein called the "Determination Date"),
     notify the Borrowers of the designation by the Banks of the new
     Borrowing Base and Monthly Commitment Reduction for the period
     beginning on such Determination Date and continuing until, but not
     including, the next Determination Date.  If an Unscheduled
     Redetermination is made by the Banks, the Agent shall notify the
     Borrowers within a reasonable time after receipt of all requested
     information of the new Borrowing Base and Monthly Commitment
     Reduction, and such new Borrowing Base and Monthly Commitment
     Reduction shall continue until the next Determination Date.  If the
     Borrowers do not furnish all such information, reports and data by any
     date specified in this Section 7(b), the Banks may nonetheless
     designate the Borrowing Base and Monthly Commitment Reduction at any
     amounts which the Banks in their discretion determine and may
     redesignate the Borrowing Base and Monthly 


                                    -27-

<PAGE>

     Commitment Reduction from time to time thereafter until the Banks 
     receive all such information, reports and data, whereupon the Banks 
     shall designate a new Borrowing Base and Monthly Commitment Reduction as 
     described above.  Each Bank shall determine the amount of the Borrowing 
     Base and Monthly Commitment Reduction based upon the loan collateral 
     value which such Bank in its discretion (using such methodology, 
     assumptions and discounts rates as such Bank customarily uses in 
     assigning collateral value to oil and gas properties, oil and gas 
     gathering systems, gas processing and plant operations) assigns to such 
     Oil and Gas Properties and other Collateral of the Borrowers at the time 
     in question and based upon such other credit factors consistently 
     applied (including, without limitation, the assets, liabilities, cash 
     flow, business, properties, prospects, management and ownership of the 
     Borrowers and their affiliates) as such Bank customarily considers in 
     evaluating similar oil and gas credits, but such Bank in its discretion 
     shall not be required to give any additional positive value to any Oil 
     and Gas Property over the current economic and pricing parameters used 
     by such Bank for such Determination Date which additional value is 
     derived directly from a hedging, forward sale or swap agreement covering 
     such Oil and Gas Property as of the date of such determination.  All 
     determinations or Unscheduled Redeterminations of the Borrowing Base and 
     the Monthly Commitment Reduction require the approval of Majority Banks; 
     provided, however, that notwithstanding anything to the contrary herein, 
     the amount of the Borrowing Base may not be increased, nor may the 
     Monthly Commitment Reduction be reduced, without the approval of all 
     Banks. If the Banks cannot otherwise agree on the Borrowing Base or the 
     Monthly Commitment Reduction, each Bank shall submit in writing to the 
     Agent its proposed Borrowing Base and Monthly Commitment Reduction and 
     the Borrowing Base and Monthly Commitment Reduction shall be set on the 
     basis of the weighted average of the Borrowing Bases and the weighted 
     average of the Monthly Commitment Reductions proposed by the Banks.  If 
     at any time any of the Oil and Gas Properties are sold, the Borrowing 
     Base then in effect shall automatically be reduced by a sum equal to the 
     amount of prepayment required to be made pursuant to Section 12(r) 
     hereof.  The Borrowing Base shall be additionally reduced from time to 
     time pursuant to the provisions of Sections 2(e) and 2(f) hereof.  It is 
     expressly understood that the Banks have no obligation to designate the 
     Borrowing Base or the Monthly Commitment Reduction at any particular 
     amounts, except in the exercise of their discretion, whether in relation 
     to the Revolving Commitment or otherwise.  Provided, however, that the 
     Banks shall not have the obligation to designate a Borrowing Base in an 
     amount in excess of the Revolving Commitment or its legal or internal 
     lending limits.  Upon the issuance of any public note issue permitted 
     pursuant to Section 13(f)(iv) hereof, the Banks shall have the right to 
     perform an Unscheduled Redetermination of the Borrowing Base.

     8.   FEES.

          (a)    UNUSED COMMITMENT FEE.  The Borrowers shall pay to Agent for
     the ratable benefit of the Banks an unused commitment fee (the "Unused
     Commitment Fee") equivalent to the Unused Fee Rate times the
     unadvanced amount of the Revolving Commitment (calculated on a daily
     basis).  The Unused Commitment Fee shall be payable in arrears on the
     last Business Day of each calendar quarter beginning June 30, 1998
     with the final fee payment due on the Maturity Date for any period
     then ending for which the Unused Commitment Fee shall not have been
     theretofore paid.  In the event the Revolving Commitment terminates on
     any date prior to the end of any such monthly period, the Borrowers
     shall pay to the Agent for the ratable benefit of the Banks, on the
     date of such termination, the total Unused Commitment Fee due for the
     period in which such termination occurs.

          (b)    THE LETTER OF CREDIT FEE.  Borrowers shall pay to the Agent
     the Letter of Credit fees required above in Section 2(d).

          (c)    AGENCY FEES.  The Borrowers shall pay to the Agent certain
     fees for acting as Agent hereunder in amounts to be negotiated between
     the Borrowers and the Agent.

          (d)    OTHER FEES. The Borrowers shall pay on the Effective Date
     the additional fees provided for in the Engagement Letter dated
     April 20, 1998 by and among Resources, Bank One-Oklahoma and Bank One
     Capital Markets, Inc.

     9.   PREPAYMENTS.

          (a)    VOLUNTARY PREPAYMENTS.  Subject to the provisions of
     Section 5(e) hereof, the Borrowers may at any time and from time to
     time, without penalty or premium, prepay the Notes, in whole or in
     part.  Each such prepayment shall be made on at least three (3) London
     Business Days' notice to Agent in the case of LIBOR Loan Tranches and
     without notice in the case of Prime Rate Loan Tranches and shall be in
     a minimum amount of $500,000 or any larger multiple thereof or the
     unpaid balance on the Notes, whichever is less, plus accrued interest
     thereon to the date of prepayment.

          (b)    MANDATORY PREPAYMENT FOR BORROWING BASE DEFICIENCY.  In the
     event the Total Outstandings ever exceed the Borrowing Base as
     determined by Banks pursuant to Section 7(b) hereof, the Borrowers
     shall, within thirty (30) days after notification from the Agent,
     either (A) by instruments reasonably satisfactory in form and
     substance to the Bank, provide the Agent with collateral with value
     and quality in amounts satisfactory to all of the Banks in their
     discretion in order to increase the Borrowing Base by an amount at
     least equal to such excess, or (B) 


                                    -29-

<PAGE>

     prepay, without premium or penalty, the principal amount of the 
     Revolving Notes in an amount at least equal to such excess plus accrued 
     interest thereon to the date of prepayment.  If the Total Outstandings 
     ever exceed the Revolving Commitment as a result of a Monthly Commitment 
     Reduction or any other required reduction in the Revolving Commitment, 
     then in such event, Borrowers shall immediately prepay the principal 
     amount of the Revolving Notes in an amount at least equal to such excess 
     plus accrued interest to the date of prepayment.

     10.  REPRESENTATIONS AND WARRANTIES.  In order to induce the Banks to
enter into this Agreement, the Borrowers hereby, jointly and severally,
represent and warrant to the Banks (which representations and warranties will
survive the delivery of the Notes) that:

          (a)    CREATION AND EXISTENCE.  Borrowers are each a corporation
     duly organized, validly existing and in good standing under the laws
     of the jurisdiction in which it was formed and is duly qualified in
     all jurisdictions wherein failure to qualify may result in a Material
     Adverse Effect.  Borrowers each have all power and authority to own
     its properties and assets and to transact the business in which it is
     engaged.

          (b)    POWER AND AUTHORITY.  Borrowers are each duly authorized and
     empowered to create and issue the Notes; and Borrowers are duly
     authorized and empowered to execute, deliver and perform their
     respective Loan Documents, including this Agreement; and all
     corporation action on each Borrower's part requisite for the due
     creation and issuance of the Notes and for the due execution, delivery
     and performance of the Loan Documents, including this Agreement, has

     authorized and empowered to execute, deliver and perform the
     respective Loan Documents to which they are a party, including the
     Subordination Agreement; and all action on each Support Party's part
     requisite for the due execution, delivery and performance of such Loan
     Documents has been duly and effectively taken.

          (c)    BINDING OBLIGATIONS.  This Agreement does, and the Notes and
     other Loan Documents upon their creation, issuance, execution and
     delivery will, constitute valid and binding obligations of Borrowers,
     enforceable in accordance with their respective terms (except that
     enforcement may be subject to applicable principles of equity and the
     effect of any applicable bankruptcy, insolvency, or similar debtor
     relief laws now or hereafter in effect and relating to or affecting
     the enforcement of creditors' rights generally). The Subordination 
     Agreement upon its creation, issuance, execution and delivery will
     constitute valid and binding obligations of each of the Support
     Parties, enforceable in accordance with their respective terms (except

     the effect of any applicable bankruptcy, insolvency, or similar debtor
     relief laws now or hereafter in effect and relating to or affecting
     the enforcement of 


                                    -30-

<PAGE>

     creditors' rights generally).

          (d)    NO LEGAL BAR OR RESULTANT LIEN.  The Notes and the Loan
     Documents, including this Agreement, do not and will not, to the best
     of each Borrower's and each Support Party's knowledge violate any
     provisions of any contract, agreement, law, regulation, order,
     injunction, judgment, decree or writ to which any Borrower or any
     Support Party is  subject which could reasonable be expected to have a
     Material Adverse Effect, or result in the creation or imposition of
     any lien or other encumbrance upon any assets or properties of any
     Borrower or any Support Party, other than those contemplated by this
     Agreement.

          (e)    NO CONSENT.  The execution, delivery and performance by the
     Borrowers of the Notes and by the Borrowers and the Support Parties of
     their respective Loan Documents, including this Agreement, does not
     require the consent or approval of any other person or entity,
     including without limitation any regulatory authority or governmental
     body of the United States or any state thereof or any political
     subdivision of the United States or any state thereof except for
     (i) consents required for federal, state and, in some instances,
     private leases, right of ways and other conveyances or encumbrances of
     oil and gas leases, if any, all of which consents have been obtained
     by the Borrowers.

          (f)    FINANCIAL CONDITION.  The unaudited Financial Statements of
     Borrowers dated December 31, 1997, which have been delivered to Banks
     are complete and correct in all material respects, and fully and
     accurately reflect in all material respects the financial condition
     and results of the operations of the Borrowers on a consolidated basis
     as of the date or dates and for the period or periods stated.  No
     change has since occurred in the condition, financial or otherwise, of
     the Borrowers which is reasonably expected to have a Material Adverse
     Effect, except as disclosed to the Banks in Schedule "2" attached
     hereto.

          (g)    LIABILITIES.  Neither Borrower has any material
     (individually or in the aggregate) liability, direct or contingent,
     except as disclosed to the Banks in the Financial Statements or on
     Schedule "3" attached hereto.  No unusual or unduly burdensome
     restrictions, restraint, or hazard exists by contract, law or
     governmental regulation or otherwise relative to the business, assets
     or properties of Borrowers which is reasonably expected to have a
     Material Adverse Effect.

          (h)    LITIGATION.  Except as described in the Financial
     Statements, or as otherwise disclosed to the Banks in Schedule "4"
     attached hereto, there is no litigation, legal or administrative
     proceeding, investigation or other action of any nature pending or, to
     the knowledge of the officers of Borrowers threatened against or
     affecting Borrowers which involves the possibility of any judgment or
     liability not fully covered by insurance, and which is reasonably
     expected to have a Material 


                                    -31-

<PAGE>

     Adverse Effect.

          (i)    TAXES; GOVERNMENTAL CHARGES.  Borrowers have each filed all
     tax returns and reports required to be filed and has paid all taxes,
     assessments, fees and other governmental charges levied upon them or
     their assets, properties or income which are due and payable,
     including interest and penalties, the failure of which to pay could
     reasonably be expected to have a Material Adverse Effect, except such
     as are being contested in good faith by appropriate proceedings and
     for which adequate reserves for the payment thereof as required by
     GAAP has been provided and levy and execution thereon have been stayed
     and continue to be stayed.

          (j)    TITLES, ETC.  Borrowers each have defensible title to all of
     its respective assets, including without limitation, the Oil and Gas
     Properties, the Plants and the Systems, free and clear of all liens or
     other encumbrances except Permitted Liens, except such failure or
     failures of title which in the aggregate could not reasonably be
     expected to reduce the Borrowing Base by more than $500,000.

          (k)    DEFAULTS.  Neither Borrower is in default and no event or
     circumstance has occurred which, but for the passage of time or the
     giving of notice, or both, would constitute a default under any loan
     or credit agreement, indenture, mortgage, deed of trust, security
     agreement or other agreement or instrument to which either Borrower is
     a party in any respect that would be reasonably expected to have a
     Material Adverse Effect.  No Event of Default hereunder has occurred
     and is continuing.

          (l)    CASUALTIES; TAKING OF PROPERTIES.  Since the dates of the
     latest Financial Statements of the Borrowers delivered to Banks,
     neither the business nor the assets or properties of Borrowers have
     been affected (to the extent it is reasonably likely to cause a
     Material Adverse Effect), as a result of any fire, explosion,
     earthquake, flood, drought, windstorm, accident, strike or other labor
     disturbance, embargo, requisition or taking of property or
     cancellation of contracts, permits or concessions by any domestic or
     foreign government or any agency thereof, riot, activities of armed
     forces or acts of God or of any public enemy.

          (m)    USE OF PROCEEDS; MARGIN STOCK.  The proceeds of the
     Revolving Commitment may be used by the Borrowers for the purposes of
     (i) refinancing existing debt owed to Bank One-Oklahoma,
     (ii) acquisition, exploration and development of oil and gas
     properties or entities owning oil and gas properties, (iii) Letters of
     Credit, and (iv) general corporate purposes.  Neither Borrower is
     engaged principally or as one of its important activities in the
     business of extending credit for the purpose of purchasing or carrying
     any "margin stock" as defined in Regulation U of the Board of
     Governors of the Federal Reserve System (12 C.F.R. Part 221), or for
     the purpose of reducing or retiring any indebtedness which was


                                    -32-

<PAGE>

     originally incurred to purchase or carry a margin stock or for any
     other purpose which might constitute this transaction a "purpose
     credit" within the meaning of said Regulation G or U.

          Neither Borrower nor any person or entity acting on behalf of
     Borrowers has taken or will take any action which might cause the
     loans hereunder or any of the Loan Documents, including this
     Agreement, to violate Regulation G or U or any other regulation of the
     Board of Governors of the Federal Reserve System or to violate the
     Securities Exchange Act of 1934 or any rule or regulation thereunder,
     in each case as now in effect or as the same may hereafter be in
     effect.

          (n)    LOCATION OF BUSINESS AND OFFICES.  The principal place of
     business and chief executive offices of the Borrowers are located at
     the address stated in Section 17 hereof.

          (o)    COMPLIANCE WITH THE LAW.  To the best of either Borrower's
     knowledge, neither Borrower:

                 (i)  is in violation of any law, judgment, decree, order,
          ordinance, or governmental rule or regulation to which either
          Borrower, or any of its assets or properties are subject; or 

                 (ii) has failed to obtain any license, permit, franchise or
          other governmental authorization necessary to the ownership of
          any of its assets or properties or the conduct of its business;

     which violation or failure is reasonably expected to have a Material
     Adverse Effect.

          (p)    NO MATERIAL MISSTATEMENTS.  No information, exhibit or
     report furnished by Borrowers to the Banks in connection with the
     negotiation of this Agreement contained any material misstatement of
     fact or omitted to state a material fact or any fact necessary to make
     the statement contained therein not materially misleading.

          (q)    ERISA.  Borrowers are each in compliance in all material
     respects with the applicable provisions of ERISA, and no "reportable
     event", as such term is defined in Section 403 of ERISA, has occurred
     with respect to any Plan of Borrowers.

          (r)    PUBLIC UTILITY HOLDING COMPANY ACT.  Neither Borrower is a
     "holding company", or "subsidiary company" of a "holding company", or
     an "affiliate" of a "holding company" or of a"subsidiary company" of a
     "holding company", or a "public utility" within the meaning of the
     Public Utility Holding 


                                    -33-

<PAGE>

     Company Act of 1935, as amended.

          (s)    SUBSIDIARIES.  All of the Borrowers' Subsidiaries are listed
     on Schedule "5" hereto.

          (t)    ENVIRONMENTAL MATTERS.  Except as disclosed on Schedule "6",
     neither Borrower (i) has received notice or otherwise learned of any
     Environmental Liability which would be reasonably likely to
     individually or in the aggregate have a Material Adverse Effect
     arising in connection with (A) any non-compliance with or violation of
     the requirements of any Environmental Law or (B) the release or
     threatened release of any toxic or hazardous waste into the
     environment, (ii) has received notice of any threatened or actual
     liability in connection with the release or notice of any threatened
     release of any toxic or hazardous waste into the environment which
     would be reasonably likely to individually or in the aggregate have a
     Material Adverse Effect or (iii) has received notice or otherwise
     learned of any federal or state investigation evaluating whether any
     remedial action is needed to respond to a release or threatened
     release of any toxic or hazardous waste into the environment for which
     either Borrower is or may be liable which may reasonably be expected
     to result in a Material Adverse Effect.

          (u)    LIENS.  Except (i) as disclosed on Schedule "1" hereto and
     (ii) for Permitted Liens, the assets and properties of the Borrowers
     are free and clear of all liens and encumbrances.

          (v)    GAS CONTRACTS.  Except as described on Schedule "7" hereto,
     the Borrowers (a) are not obligated in any material respect by virtue
     of any prepayment made under any contract containing a "take-or-pay,",
     "recoupment," or "prepayment" provision or under any similar agreement
     to deliver hydrocarbons produced from or allocated to any of the Oil
     and Gas Properties at some future date without receiving full payment
     therefor at the time of delivery, and (b) has not produced gas, in any
     material amount, subject to, and is not, nor are any of the Oil and
     Gas Properties, subject to balancing rights of third parties or
     subject to balancing duties under governmental requirements, except as
     to such matters for which the Borrowers have established monetary
     reserves adequate in an amount to satisfy such obligations and has
     segregated such reserves from other accounts or the Borrowers'
     balancing obligations in the aggregate would not reasonably be
     expected to have a Material Adverse Effect.

          (w)    YEAR 2000 COMPLIANCE.  The Borrowers have (i) initiated a
     review and assessment of all areas within each of theirs and their
     Subsidiaries' business and operations that could be adversely affected
     by the "Year 2000 Problem" (that is, the risk that computer
     applications used by the Borrowers or any of their Subsidiaries may be
     unable to recognize and perform properly date-sensitive functions
     involving 


                                    -34-

<PAGE>

     certain dates prior to and any date after December 31, 1999), (ii) 
     developed a plan and timeline for addressing the Year 2000 Problem on a 
     timely basis, and (iii) to date, implemented that plan in accordance 
     with that timetable.  The Borrowers reasonably believe that all computer 
     applications that are material to their or any of their Subsidiaries' 
     business and operations will on a timely basis be able to perform 
     properly date-sensitive functions for all dates before and after January 
     1, 2000 (that is, be "Year 2000 Compliant"), except to the extent that a 
     failure to do so could not reasonably be expected to have Material 
     Adverse Effect.

          (x)    DELHI OAKDALE LATERAL SYSTEM. A portion of the Aline
     Gathering System is not owned by either Borrower, rather, it is leased
     pursuant to the Delhi Lease.  The primary term of the Delhi Lease has
     expired, however, the Borrowers' right to use the Delhi Oakdale
     Lateral System is renewed on a month-to-month basis.  The Delhi
     Oakdale Lateral System is not a critical portion of the Aline
     Gathering System.  The Delhi Oakdale Lateral System accounts for no
     more than two percent (2%) of the volume of hydrocarbons flowing
     through the Aline Gathering System.

          (y)    ALINE GATHERING SYSTEM.  At lease ninety percent (90%) of
     the hydrocarbons flowing through the Aline Gathering System originate
     from wells directly connected to the Aline Gathering System or flows
     through the Aline Gathering System prior to delivery to the Oklahoma
     Natural Gas Company's or other purchaser's system.

     11.  CONDITIONS OF LENDING.

          (a)    The effectiveness of this Agreement, and the obligation to
     make the initial Advance or issue any initial Letter of Credit under

     by payment of rental or delay rental or by commencement or
     continuation of operations nor to prevent Borrowers from abandoning or
     releasing any oil and gas lease or other lease or well thereon when,

     faith, it is not in the best interest of the Borrowers to perpetuate
     the same.

     operators and are beyond the control of the Borrowers; however, the

                                     -43-

     Borrowers agree to promptly take all reasonable actions available
     under any operating agreements or otherwise to bring about the
     performance of any such material undertakings required to be performed
     thereunder.

          (r)       SALE OF CERTAIN ASSETS/PREPAYMENT OF PROCEEDS.  Except with
     respect to sales permitted under Section 13(a)(ii)(C) hereof, the
     Borrowers will immediately pay over to the Agent for the ratable
     benefit of the Banks as a prepayment of principal on the Revolving
     Notes, an amount equal to 100% of the Release Price received by
     Borrowers from the sale of the Oil and Gas Properties, which sale has
     been approved in advance by the Majority Banks.  The term "Release
     Price" as used herein shall mean a price determined by the Majority
     Banks in their discretion based upon the loan collateral value which
     such Banks in their discretion (using such methodology, assumptions
     and discounts rates as such Banks customarily use in assigning
     collateral value to oil and gas properties, oil and gas gathering
     systems, gas processing and plant operations) assign to such Oil and
     Gas Properties at the time in question.  Any such prepayment of
     principal on the Revolving Notes required by this Section 12(r), shall
     not be in lieu of, but shall be in addition to, any Monthly Commitment
     Reduction or any mandatory prepayment of principal required to be paid
     pursuant to Section 9(b) hereof.

          (s)       TITLE MATTERS.  Within thirty (30) days after the Effective
     Date with respect to the Oil and Gas Properties listed on Schedule "8"
     hereto, furnish Agent with title opinions and/or title information
     reasonably satisfactory to Agent showing defensible title of the
     applicable Borrower to such Oil and Gas Properties subject only to the
     Permitted Liens.  As to any Oil and Gas Properties hereafter mortgaged
     to Agent, Borrowers will promptly (but in no event more than thirty
     (30) days following such mortgaging), furnish Agent with title
     opinions and/or title information reasonably satisfactory to Agent
     covering a sufficient value of such Oil and Gas Properties to maintain
     the required level of title coverage at 72% of the Engineered Value of
     the total Oil and Gas Properties.  Said title information shall show
     defensible title of the applicable Borrower to such Oil and Gas
     Properties subject only to Permitted Liens.

          (t)       CURATIVE MATTERS.  Within sixty (60) days after the
     Effective Date with respect to matters listed on Schedule "9" and,
     thereafter, within sixty (60) days after receipt by Borrowers from
     Agent or its counsel of written notice of title defects the Agent
     reasonably requires to be cured, Borrowers shall either (i) provide
     such curative information, in form and substance satisfactory to
     Agent, or (ii) substitute Oil and Gas Properties of value and quality
     satisfactory to the Agent for all of Oil and Gas Properties for which
     such title curative was requested but upon which Borrowers elected not
     to provide such title curative information, and, within sixty (60)
     days of such substitution, provide title opinions or title information
     satisfactory to the Agent covering the Oil and Gas Properties so
     substituted.

                                     -44-
<PAGE>

          (u)       CHANGE OF PRINCIPAL PLACE OF BUSINESS.  Borrowers shall give
     Agent at least thirty (30) days prior written notice of its intention
     to move its principal place of business from the address set forth in
     Section 17 hereof.

          (v)       OPERATING ACCOUNTS.  Borrowers shall establish and maintain
     with Agent one or more operating accounts (the "Operating Accounts"),
     the maintenance of each of which shall be subject to such rules and
     regulations as the Agent shall from time to time specify.  Such
     Operating Accounts shall be the primary oil and gas operating account
     of the Borrowers and such accounts shall be maintained with the Agent
     until all amounts due hereunder and under the Notes have been paid in
     full.  The Borrowers hereby grant a security interest to Banks in and
     to the Operating Accounts and all checks, drafts and other items ever
     received by any Bank for deposit therein.  If any Event of Default
     shall occur and be continuing, Agent shall have the immediate right,
     without prior notice or demand, to take and apply against the
     Borrowers' obligations hereunder any and all funds legally and
     beneficially owned by the Borrowers then or thereafter on deposit in
     the Operating Accounts for the ratable benefit of the Banks.

          (w)       YEAR 2000 COMPLIANCE.  Borrowers will promptly notify the
     Agent in the event the Borrowers discover or determine that any
     computer application that is material to either of them or to any of
     their Subsidiaries' business and operations will not be Year 2000
     Compliant on a timely basis, except to the extent that such failure
     could not reasonably be expected to have a Material Adverse Effect.

          (x)       ADDITIONAL PROPERTY.  Borrowers shall, within five (5) days
     after receiving a written request thereof from Agent, execute and
     deliver, or cause to be executed and delivered, such mortgages, deeds
     of trust, instruments, security agreements, assignments, financing
     statements, and other documents, as may be reasonably necessary in the
     opinion of Agent and Agent's counsel, to grant Agent valid first
     mortgage liens and first, prior and perfected security interests in
     and to additional oil and gas properties of such value as Agent shall
     deem necessary to provide additional security for full and prompt
     payment of all amounts owed hereunder and under the Notes.  At Agent's
     option and on request therefor, Borrowers will furnish Agent title
     opinions covering such additional oil and gas properties prepared by
     counsel not employed by Borrowers (or such other evidence to
     Borrowers' ownership thereof and their revenue interest therein or
     attributable thereto as Agent may reasonably require), in form and
     substance satisfactory to Agent, subject only to title defects
     approved by Agent.

          (y)       ALINE GATHERING SYSTEM.  Substantially maintain the current
     levels of throughput from wells directly connected to the Aline
     Gathering System.

          (z)       LETTERS IN LIEU OF TRANSFER ORDERS.  The Borrowers shall
     promptly upon the reasonable request of the Agent, at any time and
     from time to time and without limitation on the rights of Agent in
     accordance with Section 6(c) hereof, execute such letters in lieu of
     transfer orders, in addition to the letters signed by the Borrowers
     and delivered to the Agent in satisfaction of the conditions set forth
     in Sections 6(c) and 11(a)(x) hereof, as are necessary or appropriate
     to transfer and deliver to the Agent for the benefit of the Banks
     proceeds from or attributable to any Oil and Gas Property or other
     Collateral; provided, however, that such letters shall only be
     delivered to the addressees thereof in accordance with the provision
     of Section 6(c) hereof.

          (aa)      DIVISION ORDERS.  The Borrowers shall promptly upon request
     by the Agent at any time and from time to time following the
     occurrence of any Event of Default and without limitations on the
     rights of the Agent in accordance with Section 6(c) hereof, execute
     such division and/or transfer orders as are necessary or appropriate
     to transfer and deliver to the Agent for the ratable benefit of the
     Banks proceeds from the sale of hydrocarbon production from or
     attributable to any Oil and Gas Property; provided, however, that the
     Banks shall only send or deliver such division orders and/or transfer
     orders in accordance with Section 6(c) hereof.

          (bb)      TAKE OR PAY AGREEMENT.  The Borrowers shall, in connection
     with their delivery of the engineering reports required by Sections 7
     and 12 hereof, deliver to Agent copies of contracts or other
     agreements concerning "take or pay" and "prepayment", and provide
     notice of all gas balance liabilities of the Borrowers.

     13.  Negative Covenants.  A deviation from the provisions of this
Section 13 shall not constitute a Default or an Event of Default under this
Agreement if such deviation is consented to in writing by the required
percentage of the Banks prior to the date of deviation.  The Borrowers will
at all times comply with the covenants contained in this Section 13 from the
date hereof and for so long as the Revolving Commitment is in existence or
any amount is owed to the Agent or the Banks under this Agreement or the
other Loan Documents.

          (a)       NEGATIVE PLEDGE.  Neither Borrower shall without the prior
     written consent of the Banks:

                    (i)   create, incur, assume or permit to exist any Lien,
          security interest or other encumbrance on any of its assets or
          properties except Permitted Liens; or

                    (ii)  sell, lease, transfer or otherwise dispose of, in any
          fiscal year, any of its assets except for (A) sales, leases,
          transfers or other dispositions made in the ordinary course of
          Borrowers' oil and gas businesses, (B) sales made with the
          consent of Majority Banks which are made pursuant to, and

                                     -46-
<PAGE>

          in full compliance with, Section 12(r) hereof; and (C) sales, leases
          or transfers or other dispositions made by Borrowers during any
          fiscal year, one or any series of transactions, the aggregate
          value of which does not exceed $5,000,000.00 in any such year if,
          and only if, such sale, lease, transfer or other disposition does
          not result in the occurrence of a Default or Event of Default;

          (b)       CURRENT RATIO. Borrowers shall not allow their ratio of
     consolidated Current Assets to consolidated Current Liabilities to be
     less than 1.0 to 1.0 as of the end of any fiscal quarter.

          (c)       RATIO OF DEBT TO MINIMUM TANGIBLE NET WORTH. The Borrowers
     will not allow their ratio of consolidated Debt to consolidated
     Tangible Net Worth to ever be greater than 3.25 to 1.0 as of the end
     of any fiscal quarter.

          (d)       MINIMUM DEBT SERVICE COVERAGE RATIO. Beginning with the
     calendar quarter ending September 30, 1998, the Borrowers will not
     allow their consolidated Debt Service Coverage Ratio to ever be less
     than 1.20 to 1.0.

          (e)       CONSOLIDATIONS AND MERGERS.  Neither Borrower will
     consolidate or merge with or into any other Person, except that either
     Borrower may merge with another Person if such Borrower is the
     surviving entity in such merger and if, after giving effect thereto,
     no Default or Event of Default shall have occurred and be continuing.

          (f)       DEBTS, GUARANTIES AND OTHER OBLIGATIONS.  Without the
     consent of Majority Banks, neither Borrower will incur, create, assume
     or in any manner become or be liable in respect of any indebtedness,
     nor will either Borrower guarantee or otherwise in any manner become
     or be liable in respect of any indebtedness, liabilities or other
     obligations of any other person or entity, whether by agreement to
     purchase the indebtedness of any other person or entity or agreement
     for the furnishing of funds to any other person or entity through the
     purchase or lease of goods, supplies or services (or by way of stock
     purchase, capital contribution, advance or loan) for the purpose of
     paying or discharging the indebtedness of any other person or entity,
     or otherwise, except that the foregoing restrictions shall not apply
     to:

                    (i)  the Notes and any renewal or increase thereof, or other
          indebtedness of the Borrowers heretofore disclosed to Banks in
          the Borrowers' Financial Statements or on Schedule "3" hereto; or

                    (ii) taxes, assessments or other government charges which
          are not yet due or are being contested in good faith by
          appropriate action

          promptly initiated and diligently conducted, if such reserve as shall 
          be required by GAAP shall have been made therefor and levy and 
          execution thereon have been stayed and continue to be stayed; or 

                    (iii) indebtedness (other than in connection with a loan
          or lending transaction) incurred in the ordinary course of
          business, including, but not limited to indebtedness for
          drilling, completing, leasing and reworking oil and gas wells or
          the treatment, distribution, transportation of sale of production
          therefrom and loans or lending transactions in which the
          outstanding principal balance does not exceed $500,000 at any
          time and which does not result in the imposition of a Lien other
          than a Permitted Lien; or; or

                    (iv)  indebtedness issued pursuant to an indenture providing
          for the sale of notes to the public not exceeding the face amount
          of $200,000,000, which indebtedness (A) is expressly subordinated
          (to the satisfaction of Majority Banks) to all obligations owed
          the Banks hereunder and under the Notes, (B) is issued by the
          Borrowers or an Affiliate of the Borrowers, within one hundred
          eighty (180) days of the Effective Date, and (C) the net proceeds
          of which are used in part to repay or reduce the outstanding
          balance on the Notes, said indebtedness to be approved in advance
          by Majority Banks, which approval will not be unreasonably
          withheld; or

                    (v)   other indebtedness owed to Affiliates of Borrowers
          which is expressly made subordinate to the indebtedness owed
          hereunder and under the Notes, which subordination is approved in
          advance by Majority Banks, which approval will not be
          unreasonably withheld; or

                    (vi)  any renewals or extensions of (but not increases in)
          any of the foregoing.

          (g)       DIVIDENDS OR DISTRIBUTIONS.  Neither Borrower will declare,
     pay or make, whether in cash or property (excluding stock dividends),
     or set aside or apply any money or assets to pay or make any dividend
     or distribution during any fiscal year except the foregoing
     restriction shall not apply to (i) cash dividends paid by Resources to
     its shareholders in amounts equal to each such shareholders' allocable
     share of federal or state income taxes attributable to Resources
     taxable net income and (ii) dividends made by Gas to Resources. 
     Provided, however, that no dividend shall be made by either Borrower
     if an Event of Default has occurred and is continuing or would occur
     as a result of the making of such dividends.  Resources shall provide
     the Agent at least annually with sufficient information from which
     Agent can verify all shareholders' allocable share of such income
     taxes.

     shall not apply to:

                    (i)   loans or advances to any person, the material details
          of which have been set forth in the Financial Statements of the
          Borrowers heretofore furnished to Banks; or

     material change to be made in the character of its business as carried
     on at the date hereof.

          (k)       TRANSACTIONS WITH AFFILIATES.  Neither Borrower will enter
     into any transaction with any Affiliate (other than Borrower), except
     transactions upon terms that are no less favorable to it than would be
     obtained in a transaction negotiated at arm's length with an unrelated
     third party.

          (l)       HEDGING TRANSACTIONS.  Neither Borrower will enter into any
     transaction providing (i) for the hedging, forward sale, swap or any
     deviation thereof of crude oil or natural gas or other commodities, or
     (ii) for a swap, collar, floor, cap, option, corridor, or other

     fluctuation in interest rates, as such terms are referred to in the

     (x) transactions consented to in writing by the Banks which are on
     terms acceptable to the Banks, or (y) Pre-Approved Contracts.  The
     term "Pre-Approved Contracts" as used herein shall mean any contract
     or agreement (i) to hedge, forward, sell or swap crude oil or natural
     gas or otherwise sell up to 50% of the Borrowers' monthly production

     Articles of Incorporation or Bylaws, which amendment or alteration
     could reasonably be expected to have a Material Adverse Effect.

          (o)       LEASES.  With the exception of the lease agreement, as it
     currently exists, with Harold Hamm regarding The Continental Center
     North Building located in Enid, Oklahoma, the Borrowers will not enter
     into or agree to enter into, any rental or lease agreement resulting
     or which would result in aggregate rental or lease payments of the
     Borrowers exceeding $250,000 in the aggregate in any fiscal year of
     the Borrowers under all rental or lease agreement under which either
     Borrower is a lessee of the property or assets covered thereby;

     with any document furnished hereunder, shall prove to be untrue in any
     material respect as of the date on which such representation or
     warranty is made (or deemed made), or any representation, statement
     (including financial statements), certificate, report or other data
     furnished or to be furnished or made by Borrowers under any Loan
     Document, including this Agreement, proves to have been untrue in any

     forth were stated or certified; or

          (c)       Default shall be made in the due observance or performance

     otherwise), or any obligations secured by any mortgage, pledge or
     other security interest, lien, charge or encumbrance with respect
     thereto, on any asset or property of Borrowers in respect of any
     agreement relating to any such obligations unless Borrowers are not
     liable for same (i.e., unless remedies or recourse for failure to pay
     such obligations is limited to foreclosure of the collateral security
     therefor), and if such default shall continue beyond the applicable
     grace period, if any; or 

          (f)       Borrowers shall commence a voluntary case or other
     proceedings seeking liquidation, reorganization or other relief with
     respect to itself or its debts

     under any bankruptcy, insolvency or other similar law now or hereafter

     with respect to it or its debts under any bankruptcy, insolvency or
     similar law now or hereafter in effect or seeking the appointment of a
     trustee, receiver, liquidator, custodian or other similar official of
     it or any substantial part of its property, and such involuntary case
     or other proceeding shall remain undismissed and unstayed for a period
     of sixty (60) days; or an order for relief shall be entered against
     Borrowers under the federal bankruptcy laws as now or hereinafter in
     effect; or

          (h)       A final judgment or order for the payment of money in excess
     of $1,500,000 (or judgments or orders aggregating in excess of
     $1,500,000) shall be rendered against Borrowers and such judgments or
     orders shall continue unsatisfied and unstayed for a period of thirty
     (30) days; or 

          (i)       In the event the Total Outstandings shall at any time exceed
     the Borrowing Base established for the Revolving Notes, and the
     Borrowers shall fail to comply with the provisions of Section 9(b)
     hereof; or

          (j)       A Change of Management shall occur; or

          (k)       Any Security Instrument shall for any reason not, or cease
     to, create valid and perfected first-priority Liens against the
     Collateral purportedly covered thereby and such occurrence would have
     a Material Adverse Effect; or

          (l)       The good faith determination by the Agent that a Material
     Adverse Effect has occurred or will occur or that the value of the
     Collateral has, or will be, materially decreased.

          Upon occurrence of any Event of Default specified in Subsections
     14(f) and (g) hereof, the entire principal amount due under the Notes
     and all interest then accrued thereon, and any other liabilities of
     the Borrowers hereunder, shall become immediately due and payable all
     without notice and without presentment, demand, protest, notice of
     protest or dishonor or any other notice of default of any kind, all of
     which are hereby expressly waived by the Borrowers.  In any other
     Event of Default, the Agent, upon request of Majority Banks, shall by
     notice to the 

                                     -52-
<PAGE>

     Borrowers declare the principal of, and all interest then accrued on, the 
     Notes and any other liabilities hereunder to be forthwith due and payable, 
     whereupon the same shall forthwith become due and payable without 
     presentment, demand, protest, notice of intent to accelerate, notice of 
     acceleration or other notice of any kind, all of which the Borrowers hereby
     expressly waive, anything contained herein or in the Note to the contrary 
     notwithstanding.  Nothing contained in this Section 14 shall be construed 
     to limit or amend in any way the Events of Default enumerated in the Note, 
     or any other document executed in connection with the transaction 
     contemplated herein.

          Upon the occurrence and during the continuance of any Event of
     Default, the Banks are hereby authorized at any time and from time to
     time, without notice to the Borrowers (any such notice being expressly
     waived by the Borrowers), 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 any of the Banks to
     or for the credit or the account of the Borrowers against any and all
     of the indebtedness of the Borrowers under the Notes and the Loan
     Documents, including this Agreement, irrespective of whether or not
     the Banks shall have made any demand under the Loan Documents,
     including this Agreement or the Notes and although such indebtedness
     may be unmatured.  Any amount set-off by any of the Banks shall be
     applied against the indebtedness owed the Banks by the Borrowers
     pursuant to this Agreement and the Notes.  The Banks agree promptly to
     notify the Borrowers after any such setoff and application, provided
     that the failure to give such notice shall not affect the validity of
     such set-off and application.  The rights of the Bank under this
     Section are in addition to other rights and remedies (including,
     without limitation, other rights of set-off) which the Banks may have.

     15.  THE AGENT AND THE BANKS.

          (a)       APPOINTMENT AND AUTHORIZATION.  Each Bank hereby appoints
     Agent as its nominee and agent, in its name and on its behalf: (i) to
     act as nominee for and on behalf of such Bank in and under all Loan
     Documents; (ii) to arrange the means whereby the funds of Banks are to
     be made available to the Borrowers under the Loan Documents; (iii) to
     take such action as may be requested by any Bank under the Loan
     Documents (when such Bank is entitled to make such request under the
     Loan Documents); (iv) to receive all documents and items to be
     furnished to Banks under the Loan Documents; (v) to be the secured
     party, mortgagee, beneficiary, and similar party in respect of, and to
     receive, as the case may be, any collateral for the benefit of Banks;
     (vi) to promptly distribute to each Bank all material information,
     requests, documents and items received from the Borrowers under the
     Loan Documents; (vii) to promptly distribute to each Bank such Bank's
     Pro Rata Part of each payment or prepayment (whether voluntary, as
     proceeds of insurance thereon, or otherwise) in accordance with the
     terms of the Loan Documents and (viii) to 

                                     -53-
<PAGE>

     deliver to the appropriate Persons requests, demands, approvals and 
     consents received from Banks.  Each Bank hereby authorizes Agent to take 
     all actions and to exercise such powers under the Loan Documents as are 
     specifically delegated to Agent by the terms hereof or thereof, together 
     with all other powers reasonably incidental thereto.  With respect to its 
     commitments hereunder and the Notes issued to it, Agent and any successor 
     Agent shall have the same rights under the Loan Documents as any other Bank
     and may exercise the same as though it were not the Agent; and the
     term "Bank" or "Banks" shall, unless otherwise expressly indicated,
     include Agent and any successor Agent in its capacity as a Bank. 
     Agent and any successor Agent and its Affiliates may accept deposits
     from, lend money to, act as trustee under indentures of and generally
     engage in any kind of business with the Borrowers, and any person
     which may do business with the Borrowers, all as if Agent and any
     successor Agent was not Agent hereunder and without any duty to
     account therefor to the Banks; provided that, if any payments in
     respect of any property (or the proceeds thereof) now or hereafter in
     the possession or control of Agent which may be or become security for
     the obligations of the Borrowers arising under the Loan Documents by
     reason of the general description of indebtedness secured or of
     property contained in any other agreements, documents or instruments
     related to any such other business shall be applied to reduction of
     the obligations of the Borrowers arising under the Loan Documents,
     then each Bank shall be entitled to share in such application
     according to its pro rata part thereof.  Each Bank, upon request of
     any other Bank, shall disclose to all other Banks all indebtedness and
     liabilities, direct and contingent, of the Borrowers to such Bank as
     of the time of such request.

          (b)       NOTE HOLDERS.  From time to time as other Banks become a
     party to this Agreement, Agent shall obtain execution by the Borrowers
     of additional Notes in amounts representing the Commitment of each
     such new Bank, up to an aggregate face amount of all Revolving Notes
     not exceeding $175,000,000.  The obligation of such Bank shall be
     governed by the provisions of this Agreement, including but not
     limited to, the obligations specified in Section 2 hereof.  From time
     to time, Agent may require that the Banks exchange their Notes for
     newly issued Notes to better reflect the Commitments of the Banks. 
     Agent may treat the payee of any Note as the holder thereof until
     written notice of transfer has been filed with it, signed by such
     payee and in form satisfactory to Agent.

          (c)       CONSULTATION WITH COUNSEL.  Banks agree that Agent may
     consult with legal counsel selected by Agent and shall not be liable
     for any action taken or suffered in good faith by it in accordance
     with the advice of such counsel.

          (d)       DOCUMENTS.  Agent shall not be under a duty to examine or
     pass upon the validity, effectiveness, enforceability, genuineness or
     value of any of the Loan Documents or any other instrument or document
     furnished pursuant thereto or 

                                     -54-
<PAGE>

     in connection therewith, and Agent shall be entitled to assume that the 
     same are valid, effective, enforceable and genuine and what they purport 
     to be.

          (e)       RESIGNATION OR REMOVAL OF AGENT.  Subject to the appointment
     and acceptance of a successor Agent as provided below, Agent may
     resign at any time by giving written notice thereof to Banks and the
     Borrowers, and Agent may be removed at any time with or without cause
     by all Banks.  If no successor Agent has been so appointed by all
     Banks (and approved by the Borrowers) and has accepted such
     appointment within 30 days after the retiring Agent's giving of notice
     of resignation or removal of the retiring Agent, then the retiring
     Agent may, on behalf of Banks, appoint a successor Agent.  Any
     successor Agent must be approved by Borrowers, which approval will not
     be unreasonably withheld.  Upon the acceptance of any appointment as
     Agent hereunder by a successor Agent, such successor Agent shall
     thereupon succeed to and become vested with all the rights 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 Agent, the provisions of this
     Section 15 shall continue in effect for its benefit in respect to any
     actions taken or omitted to be taken by it while it was acting as
     Agent.  To be eligible to be an Agent hereunder the party serving, or
     to serve, in such capacity must own a Pro Rata Part of the Commitments
     equal to the level of Commitment required to be held by any Bank
     pursuant to Section 28 hereof.

          (f)       RESPONSIBILITY OF AGENT.  It is expressly understood and
     agreed that the obligations of Agent under the Loan Documents are only
     those expressly set forth in the Loan Documents as to each and that
     Agent, shall be entitled to assume that no Default or Event of Default
     has occurred and is continuing, unless Agent has actual knowledge of
     such fact or has received notice from a Bank or the Borrowers that
     such Bank or the Borrowers considers that a Default or an Event of
     Default has occurred and is continuing and specifying the nature
     thereof.  Neither Agent nor any of its directors, officers, attorneys
     or employees shall be liable for any action taken or omitted to be
     taken by them under or in connection with the Loan Documents, except
     for its or their own gross negligence or willful misconduct.  Agent
     shall not incur liability under or in respect of any of the Loan
     Documents by acting upon any notice, consent, certificate, warranty or
     other paper or instrument believed by it to be genuine or authentic or
     to be signed by the proper party or parties, or with respect to
     anything which it may do or refrain from doing in the reasonable
     exercise of its judgment, or which may seem to it to be necessary or
     desirable.

          Agent shall not be responsible to Banks for any of the Borrowers'
     recitals, statements, representations or warranties contained in any
     of the Loan Documents, or in any certificate or other document
     referred to or provided for in, or received by any Bank under, the
     Loan Documents, or for the value, validity, effectiveness,
     genuineness, enforceability or sufficiency of or any of the Loan
     Documents or for 

                                     -55-
<PAGE>

     any failure by the Borrowers to perform any of its obligations hereunder 
     or thereunder.  Agent may employ agents and attorneys-in-fact and shall 
     not be answerable, except as to money or securities received by it or its 
     authorized agents, for the negligence or misconduct of any such agents or 
     attorneys-in-fact selected by it with reasonable care.

          The relationship between Agent and each Bank is only that of
     agent and principal and has no fiduciary aspects.  Nothing in the Loan
     Documents or elsewhere shall be construed to impose on Agent any
     duties or responsibilities other than those for which express
     provision is therein made.  In performing its duties and functions
     hereunder, Agent does not assume and shall not be deemed to have
     assumed, and hereby expressly disclaims, any obligation or
     responsibility toward or any relationship of agency or trust with or
     for the Borrower or any of its beneficiaries or other creditors.  As
     to any matters not expressly provided for by the Loan Documents, Agent
     shall not be required to exercise any discretion or take any action,
     but shall be required to act or to refrain from acting (and shall be
     fully protected in so acting or refraining from acting) upon the
     instructions of all Banks and such instructions shall be binding upon
     all Banks and all holders of the Notes; provided, however, that Agent
     shall not be required to take any action which is contrary to the Loan
     Documents or applicable law.

          Agent shall have the right to exercise or refrain from
     exercising, without notice or liability to the Banks, any and all
     rights afforded to Agent by the Loan Documents or which Agent may have
     as a matter of law; provided, however, Agent shall not (i) except as
     provided in Section 7(b) hereof, without the consent of Majority Banks
     designate the amount of the Borrowing Base or the Monthly Commitment
     Reduction or (ii) without the consent of all Majority Banks, take any
     other action with regard to amending the Loan Documents, waiving any
     default under the Loan Documents or taking any other action with
     respect to the Loan Documents which requires consent of all Banks. 
     Provided further, however, that no amendment, waiver, or other action
     shall be effected pursuant to the preceding clause (ii) without the
     consent of all Banks which: (i) would increase the Borrowing Base or
     decrease the Monthly Commitment Reduction, (ii) would reduce any fees
     hereunder, or the principal of, or the interest on, any Bank's Note or
     Notes, (iii) would postpone any date fixed for any payment of any fees
     hereunder, or any principal or interest of any Bank's Note or Notes,
     (iv) would materially increase any Bank's obligations hereunder or
     would materially alter Agent's obligations to any Bank hereunder, (v)
     would release Borrowers from their obligation to pay any Bank's Note
     or Notes, (vi) release any of the Collateral, (vii) would change the
     definition of all Banks, (viii) would amend, modify or change any
     provision of this Agreement requiring the consent of all the Banks,
     (ix) would waive any of the conditions precedent to the Effective Date
     or the making of any Loan or issuance of any Letter of Credit or
     (x) would extend the Revolving Maturity Date or (xi) would 

                                     -56-
<PAGE>

     amend this sentence or the previous sentence.  Agent shall not have 
     liability to Banks for failure or delay in exercising any right or power 
     possessed by Agent pursuant to the Loan Documents or otherwise unless such
     failure or delay is caused by the gross negligence of the Agent, in
     which case only the Agent responsible for such gross negligence shall
     have liability therefor to the Banks.

          (g)       INDEPENDENT INVESTIGATION.  Each Bank severally represents
     and warrants to Agent that it has made its own independent
     investigation and assessment of the financial condition and affairs of
     the Borrowers in connection with the making and continuation of its
     participation hereunder and has not relied exclusively on any
     information provided to such Bank by Agent in connection herewith, and
     each Bank represents, warrants and undertakes to Agent that it shall
     continue to make its own independent appraisal of the credit
     worthiness of the Borrowers while the Notes are outstanding or its
     commitments hereunder are in force.  Agent shall not be required to
     keep itself informed as to the performance or observance by the
     Borrowers of this Agreement or any other document referred to or
     provided for herein or to inspect the properties or books of the
     Borrowers.  Other than as provided in this Agreement, Agent shall not
     have any duty, responsibility or liability to provide any Bank with
     any credit or other information concerning the affairs, financial
     condition or business of the Borrowers which may come into the
     possession of Agent.

          (h)       INDEMNIFICATION. Banks agree to indemnify Agent, ratably
     according to their respective Commitments on a Pro Rata basis, from
     and against any and all liabilities, obligations, losses, damages,
     penalties, actions, judgments, suits, costs, expenses or disbursements
     of any proper and reasonable kind or nature whatsoever which may be
     imposed on, incurred by or asserted against Agent in any way relating
     to or arising out of the Loan Documents or any action taken or omitted
     by Agent under the Loan Documents, provided that no Bank shall be
     liable for any portion of such liabilities, obligations, losses,
     damages, penalties, actions, judgments, suits, costs, expenses or
     disbursements resulting from Agent's gross negligence or willful
     misconduct.  Each Bank shall be entitled to be reimbursed by the Agent
     for any amount such Bank paid to Agent under this Section 15(h) to the
     extent the Agent has been reimbursed for such payments by the
     Borrowers or any other Person.  THE PARTIES INTEND FOR THE PROVISIONS
     OF THIS SECTION TO APPLY TO AND PROTECT THE AGENT FROM THE
     CONSEQUENCES OF ANY LIABILITY INCLUDING STRICT LIABILITY IMPOSED OR
     THREATENED TO BE IMPOSED ON AGENT AS WELL AS FROM THE CONSEQUENCES OF
     ITS OWN NEGLIGENCE, WHETHER OR NOT THAT NEGLIGENCE IS THE SOLE,
     CONTRIBUTING OR CONCURRING CAUSE OF ANY SUCH LIABILITY.

          (i)       BENEFIT OF SECTION 15.  The agreements contained in this
     Section 15 are solely for the benefit of Agent and the Banks and are
     not for the benefit of, or to be relied upon by, the Borrowers, any
     affiliate of the Borrowers or any other person.

                                     -57-
<PAGE>

          (j)    PRO RATA TREATMENT.  Subject to the provisions of this
     Agreement, each payment (including each prepayment) by the Borrowers
     and collection by Banks (including offsets) on account of the
     principal of and interest on the Notes and fees provided for in this
     Agreement, payable by the Borrowers shall be made Pro Rata; provided,
     however, in the event that any Defaulting Bank shall have failed to
     make an Advance as contemplated under Section 3 hereof and Agent or
     another Bank or Banks shall have made such Advance, payment received
     by Agent for the account of such Defaulting Bank or Banks shall not be
     distributed to such Defaulting Bank or Banks until such Advance or
     Advances shall have been repaid in full to the Bank or Banks who
     funded such Advance or Advances.

          (k)    ASSUMPTION AS TO PAYMENTS.  Except as specifically provided
     herein, unless Agent shall have received notice from the Borrowers
     prior to the date on which any payment is due to Banks hereunder that
     the Borrowers will not make such payment in full, Agent may, but shall
     not be required to, assume that the Borrowers have made such payment
     in full to Agent on such date and Agent may, in reliance upon such
     assumption, cause to be distributed to each Bank on such due date an
     amount equal to the amount then due such Bank.  If and to the extent
     the Borrowers shall not have so made such payment in full to Agent,
     each Bank shall repay to Agent forthwith on demand such amount
     distributed to such Bank together with interest thereon, for each day
     from the date such amount is distributed to such Bank until the date
     such Bank repays such amount to Agent, at the interest rate applicable
     to such portion of the Revolving Loan.

          (l)    OTHER FINANCINGS.  Without limiting the rights to which any
     Bank otherwise is or may become entitled, such Bank shall have no
     interest, by virtue of this Agreement or the Loan Documents, in
     (a) any present or future loans from, letters of credit issued by, or
     leasing or other financial transactions by, any other Bank to, on
     behalf of, or with the Borrowers (collectively referred to herein as
     "Other Financings") other than the obligations hereunder; (b) any
     present or future guarantees by or for the account of the Borrowers
     which are not contemplated by the Loan Documents; (c) any present or
     future property taken as security for any such Other Financings; or
     (d) any property now or hereafter in the possession or control of any
     other Bank which may be or become security for the obligations of the
     Borrowers arising under any loan document by reason of the general
     description of indebtedness secured or property contained in any other
     agreements, documents or instruments relating to any such Other
     Financings.

          (m)    INTERESTS OF BANKS.  Nothing in this Agreement shall be
     construed to create a partnership or joint venture between Banks for
     any purpose.  Agent, Banks and the Borrowers recognize that the
     respective obligations of Banks under the Revolving Commitment shall
     be several and not joint and that neither Agent nor 


                                    -58-

<PAGE>

     any of Banks shall be responsible or liable to perform any of the 
     obligations of the other under this Agreement.  Each Bank is deemed to 
     be the owner of an undivided interest in and to all rights, titles, 
     benefits and interests belonging and accruing to Agent under the 
     Security Instruments, including, without limitation, liens and security 
     interests in any collateral, fees and payments of principal and interest 
     by the Borrowers under the Revolving Commitment on a Pro Rata basis.  
     Each Bank shall perform all duties and obligations of Banks under this 
     Agreement in the same proportion as its ownership interest in the Loans 
     outstanding at the date of determination thereof.

          (n)    INVESTMENTS.  Whenever Agent in good faith determines that
     it is uncertain about how to distribute to Banks any funds which it
     has received, or whenever Agent in good faith determines that there is
     any dispute among the Banks about how such funds should be
     distributed, Agent may choose to defer distribution of the funds which
     are the subject of such uncertainty or dispute.  If Agent in good
     faith believes that the uncertainty or dispute will not be promptly
     resolved, or if Agent is otherwise required to invest funds pending
     distribution to the Banks, Agent may invest such funds pending
     distribution (at the risk of the Borrowers).  All interest on any such
     investment shall be distributed upon the distribution of such
     investment and in the same proportions and to the same Persons as such
     investment.  All monies received by Agent for distribution to the
     Banks (other than to the Person who is Agent in its separate capacity
     as a Bank) shall be held by the Agent pending such distribution solely
     as Agent for such Banks, and Agent shall have no equitable title to
     any portion thereof.

     16.  EXERCISE OF RIGHTS.  No failure to exercise, and no delay in
exercising, on the part of the Agent or the Banks, any right hereunder shall
operate as a waiver thereof, nor shall any single or partial exercise thereof
preclude any other or further exercise thereof or the exercise of any other
right.  The rights of the Agent and the Banks hereunder shall be in addition to
all other rights provided by law.  No modification or waiver of any provision of
the Loan Documents, including this Agreement, or the Note nor consent to
departure therefrom, shall be effective unless in writing, and no such consent
or waiver shall extend beyond the particular case and purpose involved.  No
notice or demand given in any case shall constitute a waiver of the right to
take other action in the same, similar or other circumstances without such
notice or demand.

     17.  NOTICES.  Any notices or other communications required or
permitted to be given by this Agreement or any other documents and instruments
referred to herein must be given in writing (which may be by facsimile
transmission) and must be personally delivered or mailed by prepaid certified or

necessary out-of-pocket expenses of the Banks, including reasonable fees and
disbursements of special counsel for the Agent, in connection with the
preparation of this Agreement, any waiver or consent hereunder or any amendment
hereof or any default or Event of Default or alleged default or Event of Default
hereunder, (ii) all reasonable and necessary out-of-pocket expenses of the
Agent, including reasonable fees and disbursements of special counsel for the

Default and collection and other enforcement proceedings resulting therefrom. 
The Borrowers shall indemnify the Banks against any transfer taxes, document
taxes, assessments or charges made by any governmental authority by reason of
the execution, delivery and filing of the Loan Documents.  The obligations of
this Section 18 shall survive any termination of this Agreement, the expiration
of the Loans and the payment of all indebtedness of the Borrowers to the Banks
hereunder and under the Notes.

     19.  INDEMNITY.  The Borrowers agree to indemnify and hold harmless
the Banks and their respective officers, employees, agents, attorneys and
representatives (singularly, an "Indemnified Party", and collectively, the
"Indemnified Parties") from and against any loss, cost, liability, damage or
expense (including the reasonable fees and out-of-pocket expenses of counsel to
the Banks, including all local counsel hired by such counsel) ("Claim") incurred
by the Banks in investigating or preparing for, defending against, or providing
evidence, producing documents or taking any other action in respect of any
commenced or threatened litigation, administrative proceeding or investigation
under any federal securities law, federal or state environmental law, or any
other statute of any jurisdiction, or any regulation, or at common law or
otherwise, which is alleged to arise out of or is based upon any acts, practices
or omissions or alleged acts, practices or omissions of the Borrowers or their
agents or arises in connection with the duties, obligations or performance of
the Indemnified Parties in negotiating, preparing, executing, accepting,
keeping, completing, countersigning, issuing, selling, delivering, releasing,
assigning, handling, certifying, processing or receiving or taking any other
action with respect to the Loan Documents and all documents, items and materials
contemplated thereby even if any of the foregoing arises out of an Indemnified
Party's ordinary negligence.  The indemnity set forth herein shall be in
addition to any other obligations or liabilities of the Borrowers to the Banks
hereunder or at common law or otherwise, and shall survive any termination of
this Agreement, the expiration of the Loans and the payment of all indebtedness
of the Borrowers to the Banks hereunder and under the Notes, provided that the
Borrowers shall have no obligation under this Section to the Bank with respect
to 


                                    -60-

<PAGE>

any of the foregoing arising out of the gross negligence or willful 
misconduct of the Bank.  If any Claim is asserted against any Indemnified 
Party, the Indemnified Party shall endeavor to notify the Borrowers of such 
Claim (but failure to do so shall not affect the indemnification herein made 
except to the extent of the actual harm caused by such failure).  The 
Indemnified Party shall have the right to employ, at the Borrowers' expense, 
counsel of the Indemnified Parties' choosing and to control the defense of 
the Claim.  The Borrowers may at their own expense also participate in the 
defense of any Claim.  Each Indemnified Party may employ separate counsel in 
connection with any Claim to the extent such Indemnified Party believes it 
reasonably prudent to protect such Indemnified Party.  THE PARTIES INTEND FOR 
THE PROVISIONS OF THIS SECTION TO APPLY TO AND PROTECT EACH INDEMNIFIED PARTY 
FROM THE CONSEQUENCES OF ANY LIABILITY INCLUDING STRICT LIABILITY IMPOSED OR 
THREATENED TO BE IMPOSED ON AGENT AS WELL AS FROM THE CONSEQUENCES OF ITS OWN 
NEGLIGENCE, WHETHER OR NOT THAT NEGLIGENCE IS THE SOLE, CONTRIBUTING, OR 
CONCURRING CAUSE OF ANY CLAIM.

     20.  GOVERNING LAW.  THIS AGREEMENT IS BEING EXECUTED AND DELIVERED,
AND IS INTENDED TO BE PERFORMED, IN OKLAHOMA, OKLAHOMA COUNTY, OKLAHOMA, AND THE
SUBSTANTIVE LAWS OF OKLAHOMA SHALL GOVERN THE VALIDITY, CONSTRUCTION,
ENFORCEMENT AND INTERPRETATION OF THIS AGREEMENT AND ALL OTHER DOCUMENTS AND
INSTRUMENTS REFERRED TO HEREIN, UNLESS OTHERWISE SPECIFIED THEREIN.

     21.  INVALID PROVISIONS.  If any provision of this Agreement is held
to be illegal, invalid, or unenforceable under present or future laws effective
during the term of this Agreement, such provisions shall be fully severable and
this Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision had never comprised a part of this Agreement, and the
remaining provisions of the Agreement shall remain in full force and effect and
shall not be affected by the illegal, invalid or unenforceable provision or by
its severance from this Agreement.

     22.  MAXIMUM INTEREST RATE.  It is the intention of the parties hereto
to comply strictly with any applicable usury laws as in effect from time to time
and, in this regard, there shall never be taken, received, contracted for,
collected, charged or received on any sums advanced hereunder interest in excess
of that which would accrue at the Maximum Rate.

     If, under any circumstances, the aggregate amounts paid on the Notes
or under this Agreement or any other Loan Document include amounts which by law
are deemed interest and which would exceed the amount permitted if the Maximum
Rate were in effect, the Borrowers stipulate that such payment and collection
will have been and will be deemed to have been, to the fullest extent permitted
by applicable laws of the State of Oklahoma or the United States of America, the
result of mathematical error on the part of the Borrowers and the Agent; and the
Agent shall promptly credit the amount of such excess to the principal amount
due on the Notes, or if the principal amount due on the Notes shall have been
paid in full, refund the amount of such excess to the Borrowers (to the extent
only of such interest payments in excess of that which would have accrued and
been payable on the basis of the Maximum Rate) upon discovery of such error by


                                    -61-

<PAGE>

the Agent or notice thereof from the Borrowers.

     If the maturity of the Notes is accelerated by reason of an election
of the Agent resulting from any Event of Default or otherwise in accordance with
this Agreement, or in the event any prepayment, then such consideration that
constitutes interest under applicable laws may never include amounts which are
more than the Maximum Rate, and the amount of such excess, if any, provided for
in this Agreement or otherwise shall be canceled automatically by the Agent as
of the date of such acceleration or prepayment and, if theretofore paid, shall
be credited by the Agent on the principal amount due on the Notes, or if the
principal amount due on the Notes shall have been paid in full, refunded by the
Agent to the Borrowers.

     All sums paid, or agreed to be paid, to the Agent for the use,
forbearance and detention of the proceeds of any Advance hereunder shall, to the
extent permitted by applicable law, be amortized, prorated, allocated and spread
throughout the full term hereof until paid in full so that the actual rate of
interest is uniform but does not exceed the Maximum Rate throughout the full
term hereof.

     23.  AMENDMENTS.  This Agreement may be amended only by an instrument
in writing executed by an authorized officer of the party against whom such
amendment is sought to be enforced.

     24.  MULTIPLE COUNTERPARTS.  This Agreement may be executed in a
number of identical separate counterparts, each of which for all purposes is to
be deemed an original, but all of which shall constitute, collectively, one
agreement.  No party to this Agreement shall be bound hereby until a counterpart
of this Agreement has been executed by all parties hereto.

     25.  CONFLICT.  In the event any term or provision hereof is
inconsistent with or conflicts with any provision of the Loan Documents, the
terms or provisions contained in this Agreement shall be controlling.

     26.  SURVIVAL.  All covenants, agreements, undertakings,
representations and warranties made in the Loan Documents, including this
Agreement, the Notes or other documents and instruments referred to herein shall
survive all closings hereunder and shall not be affected by any investigation
made by any party.

     27.  PARTIES BOUND.  This Agreement shall be binding upon and inure to
the benefit of the parties hereto and their respective successors, assigns,
heirs, legal representatives and estates, provided, however, that the Borrowers
may not, without the prior written consent of all of the Banks, assign any
rights, powers, duties or obligations hereunder.

     28.  ASSIGNMENTS AND PARTICIPATIONS.

          (a)    Each Bank shall have the right to sell, assign or transfer
     all or any 


                                    -62-

<PAGE>

     part of its Note or Notes, its Commitments and its rights and 
     obligations hereunder to one or more Affiliates, Banks, financial 
     institutions, pension plans, insurance companies, investment funds, or 
     similar Persons who are Eligible Assignees or to a Federal Reserve Bank; 
     PROVIDED, that in connection with each sale, assignment or transfer 
     (other than to an Affiliate, a Bank or a Federal Reserve Bank), the 
     applicable Bank will consider the opinion and recommendation of 
     Borrowers, which opinion and recommendation shall in no way be binding 
     upon such Bank, and each such sale, assignment, or transfer (other than 
     to an Affiliate, a Bank or a Federal Reserve Bank), shall require the 
     consent of Agent, which consent will not be unreasonably withheld, and 
     the assignee, transferee or recipient shall have, to the extent of such 
     sale, assignment, or transfer, the same rights, benefits and obligations 
     as it would if it were such Bank and a holder of such Note, Commitments 
     and rights and obligations, including, without limitation, the right to 
     vote on decisions requiring consent or approval of all Banks or Majority 
     Banks and the obligation to fund its Commitments; provided, further, 
     that (1) each such sale, assignment, or transfer (other than to an 
     Affiliate, a Bank or a Federal Reserve Bank) shall be in an aggregate 
     principal amount not less than $5,000,000, (2) each remaining Bank shall 
     at all times maintain Commitments then outstanding in an aggregate 
     principal amount at least equal to $5,000,000; (3) each such sale, 
     assignment or transfer shall be of a Pro Rata portion of such Bank's 
     Revolving Commitment and its Bridge Loan Commitment, (4) no Bank may 
     offer to sell its Note or Notes, Commitments, rights and obligations or 
     interests therein in violation of any securities laws; and (5) no such 
     assignments (other than to a Federal Reserve Bank) shall become 
     effective until the assigning Bank and its assignee delivers to Agent 
     and Borrowers an Assignment and Acceptance and the Note or Notes subject 
     to such assignment and other documents evidencing any such assignment.  
     An assignment fee in the amount of $5,000 for each such assignment 
     (other than to an Affiliate, a Bank or the Federal Reserve Bank) will be 
     payable to Agent by assignor or assignee.  Within five (5) Business Days 
     after its receipt of copies of the Assignment and Acceptance and the 
     other documents relating thereto and the Note or Notes, the Borrowers 
     shall execute and deliver to Agent (for delivery to the relevant 
     assignee) a new Note or Notes evidencing such assignee's assigned 
     Commitments and if the assignor Bank has retained a portion of its 
     Commitments, a replacement Note in the principal amount of the 
     Commitments retained by the assignor (except as provided in the last 
     sentence of this paragraph (a) such Note or Notes to be in exchange for, 
     but not in payment of, the Note or Notes held by such Bank).  On and 
     after the effective date of an assignment hereunder, the assignee shall 
     for all purposes be a Bank, party to this Agreement and any other Loan 
     Document executed by the Banks and shall have all the rights and 
     obligations of a Bank under the Loan Documents, to the same extent as if 
     it were an original party thereto, and no further consent or action by 
     Borrowers, Banks or the Agent shall be required to release the 
     transferor Bank with respect to its Commitments assigned to such 
     assignee and the transferor Bank shall henceforth be so released.


                                    -63-

<PAGE>

          (b)    Each Bank shall have the right to grant participations in
     all or any part of such Bank's Notes and Commitments hereunder to one
     or more pension plans, investment funds, insurance companies,
     financial institutions or other Persons, provided, that:

                 (i)    each Bank granting a participation shall retain the
          right to vote hereunder, and no participant shall be entitled to
          vote hereunder on decisions requiring consent or approval of Bank
          or Majority Banks (except as set forth in (iii) below);

                 (ii)   in the event any Bank grants a participation hereunder,
          such Bank's obligations under the Loan Documents shall remain
          unchanged, such Bank shall remain solely responsible to the other
          parties hereto for the performance of such obligations, such Bank
          shall remain the holder of any such Note or Notes for all
          purposes under the Loan Documents, and Agent, each Bank and
          Borrowers shall be entitled to deal with the Bank granting a
          participation in the same manner as if no participation had been
          granted; and 

                 (iii)  no participant shall ever have any right by reason
          of its participation to exercise any of the rights of Banks
          hereunder, except that any Bank may agree with any participant
          that such Bank will not, without the consent of such participant
          (which consent may not be unreasonably withheld) consent to any
          amendment or waiver requiring approval of all Banks.

          (c)    It is understood and agreed that any Bank may provide to
     assignees and participants and prospective assignees and participants
     financial information and reports and data concerning Borrowers'
     properties and operations which was provided to such Bank pursuant to
     this Agreement.

          (d)    Upon the reasonable request of either Agent or Borrowers,
     each Bank will identify those to whom it has assigned or participated
     any part of its Notes and Commitment, and provide the amounts so
     assigned or participated.

                             FORM OF REVOLVING NOTE

$________________            Oklahoma City, Oklahoma            __________, 19__

     FOR VALUE RECEIVED, the undersigned CONTINENTAL RESOURCES, INC., an
Oklahoma corporation and CONTINENTAL GAS, INC., an Oklahoma corporation
(hereinafter referred to as the "Borrowers") hereby unconditionally, jointly and
severally, promise to pay to the order of ________________________ (the "Bank")
at the offices of BANK ONE, OKLAHOMA, N.A. (the "Agent") in Oklahoma City,
Oklahoma, the principal sum of ______________________ ($________________) or so
much thereof as shall be advanced under the provisions of the Credit Agreement
(as defined herein), in lawful money of the United States of America together
with interest from the date hereof until paid at the rates specified in the
Credit Agreement.  All payments of principal and interest due hereunder are
payable at the offices of Agent at 100 North Broadway, Oklahoma City, Oklahoma
73125, or at such other address as Bank shall designate in writing to Borrowers.

     The principal and all accrued interest on this Note shall be due and
payable in accordance with the terms and provisions of the Credit Agreement.

     This Note is executed pursuant to that certain Restated Credit Agreement
dated May 14, 1998 between Borrowers, the Agent and Banks (the "Credit
Agreement"), and is one of the Notes referred to therein.  Reference is made to
the Credit Agreement and the Loan Documents (as that term is defined in the
Credit Agreement) for a statement of prepayment, rights and obligations of
Borrowers, for a statement of the terms and conditions under which the due date
of this Note may be accelerated and for statements regarding other matters
affecting this Note (including without limitation the obligations of the holder
hereof to advance funds hereunder, principal and interest payment due dates,
voluntary and mandatory prepayments, exercise of rights and remedies, payment of
attorneys' fees, court costs and other costs of collection and certain waivers
by Borrowers and others now or hereafter obligated for payment of any sums due
hereunder).  Upon the occurrence of an Event of Default, as that term is defined
in the Credit Agreement and Loan Documents, the holder hereof (i) may declare
forthwith to be entirely and immediately due and payable the principal balance
hereof and the interest accrued hereon, and (ii) shall have all rights and
remedies of the Bank under the Credit Agreement and Loan Documents.  This Note
may be prepaid in accordance with the terms and provisions of the Credit
Agreement.

     Regardless of any provision contained in this Note, the holder hereof shall
never be entitled to receive, collect or apply, as interest on this Note, any
amount in excess of the Maximum Rate (as such term is defined in the Credit
Agreement), and, if the holder hereof ever receives, collects, or applies as
interest, any such amount which would be excessive interest, it shall be deemed
a partial prepayment of principal and treated hereunder as such; and, if the
indebtedness evidenced hereby is paid in full, any remaining excess shall
forthwith be paid to Borrowers.  In determining whether or not the interest paid
or payable, under any specific contingency, exceeds the Maximum Rate, Borrowers
and the holder hereof shall, to the maximum extent permitted under applicable
law (i) characterize any non-principal payment as an expense, fee or premium
rather than as interest, (ii) exclude voluntary prepayments and the effects
thereof, and (iii) spread the total amount of interest throughout the entire
contemplated term of the obligations evidenced by this Note and/or 

<PAGE>

referred to in the Credit Agreement so that the interest rate is uniform 
throughout the entire term of this Note; provided that, if this Note is paid 
and performed in full prior to the end of the full contemplated term thereof; 
and if the interest received for the actual period of existence thereof 
exceeds the Maximum Rate, the holder hereof shall refund to Borrowers the 
amount of such excess or credit the amount of such excess against the 
indebtedness evidenced hereby, and, in such event, the holder hereof shall 
not be subject to any penalties provided by any laws for contracting for, 
charging, taking, reserving or receiving interest in excess of the Maximum 
Rate.

     If any payment of principal or interest on this Note shall become due on a
day other than a Business Day (as such term is defined in the Credit Agreement),
such payment shall be made on the next succeeding Business Day and such
extension of time shall in such case be included in computing interest in
connection with such payment.

     If this Note is placed in the hands of an attorney for collection, or if it
is collected through any legal proceeding at law or in equity or in bankruptcy,
receivership or other court proceedings, Borrowers agree to pay all costs of
collection, including, but not limited to, court costs and reasonable attorneys'
fees.

     Borrowers and each surety, endorser, guarantor and other party ever liable
for payment of any sums of money payable on this Note, jointly and severally
waive presentment and demand for payment, notice of intention to accelerate the
maturity, protest, notice of protest and nonpayment, as to this Note and as to
each and all installments hereof, and agree that their liability under this Note
shall not be affected by any renewal or extension in the time of payment hereof,
or in any indulgences, or by any release or change in any security for the
payment of this Note, and hereby consent to any and all renewals, extensions,
indulgences, releases or changes.

     This Note shall be governed by and construed in accordance with the
applicable laws of the United States of America and the laws of the State of
Oklahoma.

     THIS WRITTEN NOTE, THE CREDIT AGREEMENT AND THE OTHER LOAN DOCUMENTS
REPRESENT THE FINAL AGREEMENTS BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED
BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE
PARTIES.  THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

     This Note is one of a series of notes given in renewal, extension and
increase of (but not in extinguishment of) that certain Promissory Note dated as
of December 31, 1997, in the face amount of $75,000,000 executed by Borrowers
and payable to the order of Bank One, Oklahoma, N.A.

notice to the Trustee or the Holders, without incurring responsibility to the

Senior Debt or Guarantor Senior Debt, as the case may be, do any one or more 
of the following: (a) change the manner, place or terms of payment or extend

          Each of the Subsidiary Guarantors hereby, jointly and severally, 
unconditionally guarantees to each Holder of a Security authenticated and 
delivered by the Trustee and to the Trustee and its successors and assigns, 
irrespective of the validity and enforceability of this Indenture, the 
Securities or the obligations of the Company hereunder or thereunder, that:  
(a) the principal of and premium and interest, on the Securities shall be 
promptly paid in full when due, whether at maturity, by acceleration, 
redemption or otherwise, and interest on the overdue principal of and 
interest on premium and interest, on the Securities, if any, if lawful, and 
all other obligations of the Company to the Holders or the Trustee hereunder 
or thereunder shall be promptly paid in full or performed, all in accordance 
with the terms hereof and thereof; and (b) in case of any extension of time 
of payment or renewal of any Securities or any of such other obligations, 
that the same shall be promptly paid in full when due or performed in 
accordance with the terms of the extension or renewal, whether at stated 
maturity, by acceleration or otherwise.  Failing payment when due of any 
amount so guaranteed or any performance so guaranteed for whatever reason, 
the Subsidiary Guarantors shall be jointly and severally obligated to pay the 
same immediately.  The Subsidiary Guarantors hereby agree that their 
obligations hereunder shall be unconditional, irrespective of the validity, 
regularity or enforceability of the Securities or this Indenture, the absence 
of any action to enforce the same, any waiver or consent by any Holder with 
respect to any provisions hereof or thereof, the recovery of any judgment 
against the Company, any action to enforce the same or any other circumstance 
which might otherwise constitute a legal or equitable discharge or defense of 
a guarantor. Each of the Subsidiary Guarantors hereby waives diligence, 
presentment, demand of payment, filing of claims with a court in the event of 
insolvency or bankruptcy of the Company, ay right to require a proceeding 
first against the Company, protest, notice and all demands whatsoever and 
covenant that this Subsidiary Guarantee shall not be discharged except by 
complete performance of the obligations contained in the Securities and this 
Indenture.  If any Holder or the Trustee is required by any court or 
otherwise to return to the Company or the Subsidiary Guarantors, or any 
Custodian, Trustee, liquidator or other similar official acting in relation 
to either the Company or the Subsidiary Guarantors, any amount paid by either 
to the Trustee or such Holder, this Subsidiary Guarantee, to the extent 
theretofore discharged, shall be reinstated in full force and effect.  Each 
of the Subsidiary Guarantors agrees that it shall not be entitled to any 
right of subrogation in relation to the Holders of Securities in respect of 
any obligations guaranteed hereby until payment in full of all obligations 
guaranteed hereby.  Each of the Subsidiary Guarantors further agrees that, as 
between the Subsidiary Guarantors, on the one hand, and the Holders and the 
Trustee, on the other hand, (x) the maturity of the obligations guaranteed 
hereby may be accelerated as provided in Article 6 for the purposes of this 
Subsidiary Guarantee, notwithstanding any stay, injunction or other 
prohibition preventing such acceleration in respect of the obligations 
guaranteed hereby and (y) in the event of any declaration of

acceleration of such obligations as provided in Article 6, such obligations 
(whether or not due and payable) shall forthwith become due and payable by 
the Subsidiary Guarantors for the purpose of this Subsidiary Guarantee.  The 
Subsidiary Guarantors shall have the right to seek contribution from any 
Subsidiary Guarantor not paying so long as the exercise of such right does 
not impair the rights of the Holders under the Subsidiary Guarantees.

          Section 11.2.  SUBORDINATION OF SUBSIDIARY GUARANTEES.

          The obligations of each of the Subsidiary Guarantors under its 
Subsidiary Guarantee pursuant to this Article 11 shall be junior and 
subordinated to the Guarantor Senior Debt of the Subsidiary Guarantor 
pursuant to Article 10 hereof.  For the purposes of the foregoing sentence, 
the Trustee and the Holders shall have the right to receive and/or retain 
payments or distributions by or on behalf of any of the Subsidiary Guarantors 
only at such times as they may receive and/or retain payments in respect of 
the Securities pursuant to this Indenture, including Article 10 hereof.

          Section 11.3.  SUBSIDIARY GUARANTORS MAY CONSOLIDATE, ETC., ON 
CERTAIN TERMS.

          No Subsidiary Guarantor may consolidate with or merge with or into 
(whether or not such Subsidiary Guarantor is the Surviving Person), another 
Person other than the Company or another Subsidiary Guarantor, whether or not 
affiliated with such Subsidiary Guarantor, unless:

          (a)  subject to the provisions of Section 11.4 hereof, the Person
     formed by or surviving any such consolidation or merger (if other than such
     Subsidiary Guarantor) assumes all the obligations of such Subsidiary
     Guarantor pursuant to a supplemental indenture in form reasonably
     satisfactory to the Trustee in respect of the Securities, this Indenture
     and such Subsidiary Guarantor's Guarantee;

          (b)  immediately after giving effect to such transaction, no Default
     or Event of Default exists; and

          (c)  such transaction does not violate any of Sections 4.3, 4.7, 4.8,
     4.9, 4.10, 4.11, 4.12, 4.13, 4.14, 4.16, 4.17, 4.18 and 4.19.

Notwithstanding the foregoing, none of the Subsidiary Guarantors shall be 
permitted to consolidate with or merge with or into (whether or not such 
Subsidiary Guarantor is the surviving Person), another corporation, Person or 
entity pursuant to the preceding sentence if such consolidation or merger 
would not be permitted by Section 5.1 hereof.

          In case of any such consolidation or merger and upon the assumption 
by the successor corporation, by supplemental indenture, executed and 
delivered to the Trustee and satisfactory 


<PAGE>
                                                                           105

in form to the Trustee, of the Subsidiary Guarantee endorsed upon the 
Securities and the due and punctual performance of all of the covenants and 
conditions of this Indenture to be performed by such Subsidiary Guarantor, 
such successor corporation shall succeed to and be substituted for such 
Subsidiary Guarantor with the same effect as if it had been named herein as a 
Subsidiary Guarantor.  Such successor corporation thereupon may cause to be 
signed any or all of the Subsidiary Guarantees to be endorsed upon all of the 
Securities issuable hereunder which theretofore shall not have been signed by 
the Company and delivered to the Trustee.  All the Subsidiary Guarantees so 
issued shall in all respects have the same legal rank and benefit under this 
Indenture as the Subsidiary Guarantees theretofore and thereafter issued in 
accordance with the terms of this Indenture as though all of such Subsidiary 
Guarantees had been issued at the date of the execution hereof.

          Except as set forth in Articles 4 and 5 hereof, nothing contained 
in this Indenture or in any of the Securities shall prevent any consolidation 
or merger of any Subsidiary Guarantor with or into the Company or another 
Subsidiary Guarantor, or shall prevent any sale or conveyance of the property 
of any Subsidiary Guarantor as an entirety or substantially as an entirety to 
the Company or any Subsidiary Guarantor.

          Section 11.4.  RELEASES OF SUBSIDIARY GUARANTEES.

          In the event of a sale or other disposition of all or substantially 
all of the assets of any Subsidiary Guarantor or a sale or other disposition 
of all of the capital stock of any Subsidiary Guarantor, to any corporation 
or other Person (including an Unrestricted Subsidiary) by way of merger, 
consolidation, or otherwise, in a transaction that does not violate any of 
the covenants of this Indenture, then such Subsidiary Guarantor (in the event 
of a sale or other disposition, by way of such merger, consolidation or 
otherwise, of all the capital stock of such Subsidiary Guarantor) shall be 
released and relieved of any obligations under its Subsidiary Guarantee and 
such acquiring corporation or other Person (in the event of a sale or other 
disposition of all or substantially all of the assets of such Subsidiary 
Guarantor), if other than a Subsidiary Guarantor, shall have no obligation to 
assume or otherwise become liable under such Subsidiary Guarantee; PROVIDED 
that the Net Proceeds of such sale or other disposition are applied in 
accordance with Section 4.10 hereof. Upon delivery by the Company to the 
Trustee of an Officers' Certificate and an Opinion of Counsel to the effect 
that such sale or other disposition was made by the Company in accordance 
with the provisions of this Indenture, including without limitation Section 
4.10, the Trustee shall execute any documents reasonably required in order to 
evidence the release of any Subsidiary Guarantor from its obligations under 
its Subsidiary Guarantee.

          Any Subsidiary Guarantor not released from its obligations under 
its Subsidiary Guarantee shall remain liable for the full amount of principal 
of and interest on the

                                                                           106

Securities and for the other obligations of such Subsidiary Guarantor under 
this Indenture as provided in this Article 11.

          Any Subsidiary Guarantor that is designated an Unrestricted 
Subsidiary in accordance with the terms of this Indenture shall, upon such 
designation, be released from and relieved of its obligations under its 
Subsidiary Guarantee and any Unrestricted Subsidiary whose obligation as such 
is revoked and any newly created or newly acquired Subsidiary that is or 
becomes a Restricted Subsidiary shall be required to execute a Subsidiary 
Guarantee in accordance with the terms of this Indenture.

          Section 11.5.  LIMITATION ON SUBSIDIARY GUARANTOR LIABILITY.

          For purposes hereof, each Subsidiary Guarantor's liability shall be 
that amount from time to time equal to the aggregate liability of such 
Subsidiary Guarantor thereunder, but shall be limited to the lesser of (i) 
the aggregate amount of the Obligations of the Company under the Securities 
and this Indenture and (ii) the amount, if any, which would not have (A) 
rendered such Subsidiary Guarantor "INSOLVENT" (as such term is defined in 
the federal Bankruptcy Law and in the Debtor and Creditor Law of the State of 
New York) or (B) left it with unreasonably small capital at the time its 
Subsidiary Guarantee of the Securities was entered into, after giving effect 
to the incurrence of existing Indebtedness immediately prior to such time; 
PROVIDED that, it shall be a presumption in any lawsuit or other proceeding 
in which such Subsidiary Guarantor is a party that the amount guaranteed 
pursuant to its Subsidiary Guarantee is the amount set forth in clause (i) 
above unless any creditor, or representative of creditors of such Subsidiary 
Guarantor, or debtor in possession or trustee in bankruptcy of such 
Subsidiary Guarantor, otherwise proves in such a lawsuit that the aggregate 
liability of such Subsidiary Guarantor is limited to the amount set forth in 
clause (ii).  In making any determination as to the solvency or sufficiency 
of capital of a Subsidiary Guarantor in accordance with the previous 
sentence, the right of such Subsidiary Guarantor to contribution from other 
Subsidiary Guarantors and any other rights such Subsidiary Guarantor may 
have, contractual or otherwise, shall be taken into account.

          Section 11.6.  "TRUSTEE" TO INCLUDE PAYING AGENT.

          In case at any time any Paying Agent other than the Trustee shall 
have been appointed by the Company and be then acting hereunder, the term 
"TRUSTEE" as used in Article 10 and this Article 11 shall in such case 
(unless the context shall otherwise require) be construed as extending to and 
including such Paying Agent within its meaning as fully and for all intents 
and purposes as if such Paying Agent were named in Article 10 and this 
Article 11 in place of the Trustee.

provision of the TIA that may be so modified or excluded, the latter 
provision shall be deemed to apply to this Indenture as so modified or 
excluded, as the case may be.

     precedent have been complied with.

          Section 12.5.  STATEMENTS REQUIRED IN CERTIFICATE OR OPINION.

          Each certificate or opinion with respect to compliance with a 
condition or covenant provided for in this Indenture (other than a 
certificate provided pursuant to TIA Section 314(a)(4)) shall comply with 
the provisions of TIA Section 314(e) and shall include:

          (a)  a statement that the Person making such certificate or opinion
     has read such covenant or condition;

          (b)  a brief statement as to the nature and scope of the examination

Company or any Subsidiary, as such, shall have any liability for any 
obligations of the Company under the Securities or this Indenture or for any 
claim based on, in respect of, or by reason of, such obligations or their 
creation.  Each Holder of Securities, by accepting a Security, waives and 
releases all such liability. The waiver and release are part of the 
consideration for issuance of the Securities.  Such waiver may not be 
effective to waive liabilities under the federal securities laws and it is 
the view of the Commission that such a waiver is against public policy.

          This Indenture may not be used to interpret any other indenture, 
loan or debt agreement of the Company or their respective Subsidiaries or of 
any other Person.  Any such indenture, loan or debt agreement may not be used 
to interpret this Indenture and the Subsidiary Guarantees.

          Section 12.10.  SUCCESSORS.

          All agreements of the Company and each Subsidiary Guarantor in this 
Indenture, the Securities and the Subsidiary Guarantees shall bind its 
respective successors.  All agreements of the Trustee in this Indenture shall 
bind its successors.

          Section 12.11.  SEVERABILITY.

                       10 1/4% Senior Subordinated Notes due 2008

         Capitalized terms used herein shall have the meanings assigned to 
them in the Indenture referred to below unless otherwise indicated.

         1.  INTEREST.  Continental Resources, Inc., an Oklahoma corporation 
(the "COMPANY"), promises to pay interest on the principal amount of this 
Security at the rate of 10 1/4% per annum, which interest shall be payable in 
cash semiannually in arrears on each February 1 and August 1, or if any such 
day is not a Business Day, on the next succeeding Business Day (each an 
"INTEREST PAYMENT DATE"); PROVIDED that the first Interest Payment Date shall 
be February 1, 1999.  Interest on the Securities will accrue from the most 
recent date to which interest has been paid or, if no interest has been paid, 
from the date of original issuance.  Interest will be computed on the basis 
of a 360-day year comprised of twelve 30-day months.

         2.  METHOD OF PAYMENT.  On each Interest Payment Date the Company 
will pay interest to the Person who is the Holder of record of this Security 
as of the close of business on the January 15 or July 15 immediately 
preceding such Interest Payment Date, even if this Security is cancelled 
after such record date and on or before such Interest Payment Date, except as 
provided in Section 2.12 of the Indenture with respect to defaulted interest. 
Principal, premium, if any, and interest on this Security will be payable at 
the office or agency of the Company maintained for such purpose within The 
City and State of New York or, in the event the Securities do not remain in 
book-entry form, at the option of the Company, payment of interest may be 
made by check mailed to the Holder of this Security at its address set forth 
in the register of Holders of Securities; PROVIDED that all payments with 
respect to the Global Securities and Definitive Securities having an 
aggregate principal amount of $5.0 million or more the Holders of which have 
given wire transfer instructions to the Company at least 10 Business Days 
prior to the applicable payment date will be required to be made by wire 
transfer of immediately available funds to the accounts specified by the 
Holders thereof.  Such payment shall be in such coin or currency of the 
United States of America as at the time of payment is legal tender for 
payment of public and private debts.

         3.  PAYING AGENT AND REGISTRAR.  Initially, United States Trust 
Company of New York, the Trustee under the Indenture, will act as Paying 
Agent and Registrar.  The Company may change any Paying Agent or Registrar 
without notice to any Holder.  The Company or any Subsidiary Guarantor or any 
other of the Company's Subsidiaries may act in any such capacity.

         4.  INDENTURE.  The Company issued the Securities under an Indenture 
dated as of July 24, 1998 ("INDENTURE") among 


                                       A-5

the Company, the Subsidiary Guarantors and the Trustee.  The terms of the 
Securities include those stated in the Indenture and those made part of the 
Indenture by reference to the Trust Indenture Act of 1939, as amended 
(15 U.S. Code Sections  77aaa-77bbbb).  The Securities are subject to all 
such terms, and Holders are referred to the Indenture and such Act for a 
statement of such terms.  The Securities are general unsecured obligations of 
the Company equal in an aggregate principal amount to $150,000,000 and will 
mature on August 1, 2008.

         The Securities are general unsecured senior subordinated obligations 
of the Company limited to $150,000,000 million aggregate principal amount 
(subject to Section 2.7 of the Indenture).  The aggregate principal amount of 
notes which may be authenticated and delivered under the Indenture, including 
the Securities, is limited to $300.0 million (subject to Section 2.7 of the 
Indenture).  This Security is one of the Initial Securities referred to in 
the Indenture.  The Securities include the Initial Securities and any 
Exchange Securities issued in exchange for the Initial Securities pursuant to 
the Indenture and the Registration Rights Agreement.  The Initial Securities 
and the Exchange Securities are treated as a single class of securities under 
the Indenture.  The Indenture imposes certain limitations on the incurrence 
of Indebtedness by the Company and its Restricted Subsidiaries, the payment 
of dividends and other distributions on the Capital Stock of the Company and 
its Restricted Subsidiaries, the purchase or redemption of Capital Stock of 
the Company and Capital Stock of such Restricted Subsidiaries, certain 
purchases or redemptions of Subordinated Indebtedness, the sale or transfer 
of assets and Capital Stock of Restricted Subsidiaries, the issuance or sale 
of Capital Stock of Restricted Subsidiaries, the Investments of the Company 
and its Subsidiaries and transactions with Affiliates.  In addition, the 
Indenture limits the ability of the Company and its Restricted Subsidiaries 
to restrict distributions and dividends from Restricted Subsidiaries.

         To guarantee the due and punctual payment of the principal, premium, 
if any, and interest on the Securities and all other amounts payable by the 
Company under the Indenture and the Securities when and as the same shall be 
due and payable, whether at maturity, by acceleration or otherwise, according 
to the terms of the Securities and the Indenture, the Subsidiary Guarantors 
have unconditionally guaranteed (and future Subsidiary Guarantors, together 
with the Subsidiary Guarantors, will unconditionally guarantee), jointly and 
severally, such obligations on a senior subordinated basis pursuant to the 
terms of the Indenture.

         7.  REPURCHASE AT OPTION OF HOLDER.

         (a)  Upon the occurrence of a Change of Control, if the Company does 
not redeem the Securities pursuant to paragraph 5(c), each Holder of 
Securities shall have the right to require the Company to repurchase all or 
any part (equal to $1,000 or an integral multiple thereof) of such Holder's 
Securities pursuant to the offer described below (the "Change of Control 
Offer") at an offer price in cash equal to 101% of the aggregate principal 
amount thereof plus accrued and unpaid interest, if any, thereon to the date 
of purchase (the "Change of Control Payment").  The right of the Holders of 
the Securities to require the Company to repurchase such Securities upon a 
Change of Control may not be waived by the Trustee without the approval of 
the Holders of the Securities required by Section 9.2 of the Indenture.  
Within 30 days following any Change of Control, the Company will mail a 
notice to each Holder describing the transaction or transactions that 
constitute the Change of Control and offering to repurchase Securities 
pursuant to the procedures required by the Indenture and described in such 
notice.  The Change of Control Payment shall be made on a business day not 
less than 30 days nor more than 60 days after such notice is mailed.  The 
Company and each Subsidiary Guarantor will comply with the requirements of 
Rule 14e-1 under the Exchange Act and any other securities laws and 
regulations thereunder to the extent such laws and regulations are applicable 
in connection with the repurchase of the Securities as a result of a Change 
of Control.

               (b)  If the Company or a Restricted Subsidiary consummates any 
Asset Sales permitted by the Indenture, when the aggregate amount of Excess 
Proceeds exceeds $15 million, the Company shall make an Asset Sale Offer to 
purchase the maximum principal amount of Securities and any other Pari Passu 
Indebtedness to which the Asset Sale Offer applies that may be purchased out 
of the Excess Proceeds, at an offer price in cash in an amount equal to, in 
the case of the Securities, 100% of the principal amount thereof, plus 
accrued and unpaid interest thereon to the date of purchase or, in the case 
of any Pari Passu Indebtedness, 100% of the principal amount thereof (or with 
respect to discount Pari Passu Indebtedness, the accreted value thereof) on 
the date of purchase, in each case, in accordance with the procedures set 
forth in Section 3.9 of the Indenture or the agreements governing the Pari 
Passu Indebtedness, as applicable.  To the extent that the aggregate 
principal amount (or accreted value, as the case may be) of Securities, and 
Pari Passu Indebtedness tendered pursuant to an Asset Sale Offer is less than 
the Excess Proceeds, the Company may use any remaining Excess Proceeds for 
general corporate purposes.  If the sum of (i) the aggregate principal amount 
of Securities surrendered by Holders thereof and (ii) the aggregate principal 
amount or accreted value, as the case may be, of Pari Passu Indebtedness 
surrendered by holders or lenders thereof exceeds the amount of Excess 
Proceeds, the Trustee and the trustee or other lender representative for the 
Pari Passu Indebtedness shall select the Securities and the other Pari Passu 
Indebtedness to be purchased on a pro rata basis, based on the aggregate 
principal amount (or accreted value, as applicable) thereof surrendered in 
such Asset 


                                       A-8

Sale Offer.  Upon completion of such Asset Sale Offer, the amount of Excess 
Proceeds shall be reset at zero.

         8.  NOTICE OF REDEMPTION.  Notice of redemption will be mailed at 
least 30 days but not more than 60 days before the redemption date to each 
Holder whose Securities are to be redeemed at its registered address. 
Securities in denominations larger than $1,000 may be redeemed in part but 
only in integral multiples of $1,000, unless all of the Securities held by a 
Holder are to be redeemed.  On and after the redemption date interest ceases 
to accrue on the aggregate principal amount of the Securities called for 
redemption.

         9.  DENOMINATIONS, TRANSFER, EXCHANGE.  The Securities may be issued 
initially in the form of one or more fully registered Global Securities.  The 
Securities may also be issued in registered form without coupons in minimum 
denominations of $1,000 and integral multiples of $1,000.  The transfer of 
Securities may be registered and Securities may be exchanged as provided in 
the Indenture.  The Registrar and the Trustee may require a Holder, among 
other things, to furnish appropriate endorsements and transfer documents and 
the Company may require a Holder to pay any taxes and fees required by law or 
permitted by the Indenture.  The Company need not exchange or register the 
transfer of any Security or portion of a Security selected for redemption, 
except for the unredeemed portion of any Security being redeemed in part.  
Also, it need not exchange or register the transfer of any Security for a 
period of 15 days before a selection of Securities to be redeemed or during 
the period between a record date and the corresponding Interest Payment Date.

         10. PERSONS DEEMED OWNERS.  The registered Holder of a Security may 
be treated as its owner for all purposes.

         11. AMENDMENT, SUPPLEMENT AND WAIVER.  Subject to certain 
exceptions, the Indenture or the Securities may be amended or supplemented 
with the consent of the Holders of at least a majority in aggregate principal 
amount of the Securities then outstanding (including, without limitation, 
consents obtained in connection with a purchase of, or the tender offer or 
exchange offer for, such Securities), and any existing Default or Event of 
Default under, or compliance with any provision of the Indenture or the 
Securities may be waived with the consent of the Holders of a majority in 
principal amount of the then outstanding Securities.  Without the consent of 
any Holder of a Security, the Indenture or the Securities may be amended or 
supplemented to cure any ambiguity, defect or inconsistency, to provide for 
uncertificated Securities in addition to or in place of certificated 
Securities, to provide for the assumption of the Company's obligations to 
Holders of the Securities in case of a merger or consolidation, to make any 
change that would provide any additional rights or benefits to the Holders of 
the Securities or that does not adversely affect the legal rights under the 
Indenture of any such Holder, to add guarantees with respect to the 
Securities or to secure the Securities or to comply with the requirements of 
the Commission in order to effect

or covenants in, or provisions of, this Security or in the Indenture; (vi) 
except as permitted by the Indenture, any Subsidiary Guarantee shall be held 
in any judicial proceeding to be unenforceable or invalid or shall cease for 
any reason to be in full force and effect or a Subsidiary Guarantor or any 
Person acting on behalf of a Subsidiary Guarantor, shall deny or disaffirm 
such Subsidiary Guarantor's obligations under its Subsidiary Guarantee; (vii) 
default under any mortgage, indenture or instrument under which there may be 
issued or by which there may be secured or evidenced any Indebtedness for 
money borrowed by the Company or any Restricted Subsidiary whether such 
Indebtedness or guarantee now exists, or is created after the date of the 
Indenture, which default (a) is caused by a failure to pay principal of such 
Indebtedness prior to the expiration of the grace period provided in such 
Indebtedness on the date of such default (a "Payment Default") or (b) results 
in the acceleration of such Indebtedness prio to its express maturity and, in 
each case, the principal amount of any such Indebtedness, together with the 
principal amount of any other such Indebtedness under which there is then 
existing a Payment Default or the maturity of which has been so accelerated, 
aggregates $10 million or more; (viii) a final non-appealable judgment or 
order or final non-appealable judgments or orders are rendered against the 
Company or any Restricted Subsidiary that remain unpaid or discharged for a 
period of 60 days and that require the payment in money, either individually 
or in an aggregate amount, that is more than $10 million; and (ix) certain 
events of bankruptcy or insolvency with respect to  the Company or any 
Restricted Subsidiary.  If any Event of Default (other than an Event of 
Default described in clause (ix) above) occurs and is continuing, the Trustee 
or the Holders of at least 25% in aggregate principal amount of the then 
outstanding Securities may declare all the Securities to be due and payable 
immediately.  Notwithstanding the foregoing, in the case of an Event of 
Default arising from certain events of bankruptcy or insolvency with respect 
to the Company or any Restricted Subsidiary, all outstanding Securities will 
become due and payable without further action or notice.  Holders of the 

                                     A-10

<PAGE>

Securities may not enforce the Indenture or the Securities except as provided 
in the Indenture.  Subject to certain limitations, Holders of a majority in 
aggregate principal amount of the then outstanding Securities may direct the 
Trustee in its exercise of any trust or power.  The Trustee may withhold from 
Holders of the Securities notice of any continuing Default or Event of 
Default (except a Default or Event of Default relating to the payment of 
principal or interest) if it determines that withholding notice is in their 
interest.  The Holders of a majority in aggregate principal amount of the 
Securities then outstanding by notice to the Trustee may on behalf of the 
Holders of all of the Securities waive any existing Default or Event of 
Default and its consequences under the Indenture except a continuing Default 
or Event of Default in the payment of interest or premium on, or the 
principal of, the Securities.  The Company is required to deliver to the 
Trustee annually a statement regarding compliance with the Indenture, and the 
Company is required, within 5 Business days after becoming aware of any 
Default or Event of Default, to deliver to the Trustee a statement specifying 
such Default or Event of Default.

          13.  SUBORDINATION.  The Securities are subordinated to Senior Debt 
of the Company and the Subsidiary Guarantees are subordinated to Guarantor 
Senior Debt of the Subsidiary Guarantors.  To the extent provided in the 
Indenture, Senior Debt must be paid before the Securities may be paid and 
Guarantor Senior Debt of a Subsidiary Guarantor must be paid before a 
Subsidiary Guarantor may pay under its Subsidiary Guarantee.  The Company 
agrees, and each Holder by accepting a Security agrees, that the Indebtedness 
evidenced by the Securities, including, but not limited to, the payment of 
principal of, premium, if any, and interest on the Securities, and any other 
payment Obligation of the Company in respect of the Securities and the 
obligations of each Subsidiary Guarantor under its Subsidiary Guarantee are 
subordinated in right of payment, to the extent and in the manner provided in 
the Indenture, to the prior payment in full in cash of all Senior Debt of the 
Company and, in the case of a Subsidiary Guarantee, all Guarantor Senior Debt 
of such Subsidiary Guarantor (whether outstanding on the date hereof or 
hereafter created, incurred, assumed or guaranteed) and authorizes the 
Trustee to give effect and appoints the Trustee as attorney-in-fact for such 
purpose.

          14.  TRUSTEE DEALINGS WITH COMPANY.  The Indenture contains certain 
limitations on the rights of the Trustee, should it become a creditor of the 
Company, to obtain payment of claims in certain cases, or to realize on 
certain property received in respect of any such claim as security or 
otherwise.  The Trustee will be permitted to engage in other transactions; 
however, if it acquires any conflicting interest it must eliminate such 
conflict within 90 days, apply to the Commission for permission to continue 
or resign.

          15.  NO RECOURSE AGAINST OTHERS.  No director, officer, employee, 
incorporator or stockholder of the Company, as such, shall have any liability 
for any obligations of the Company under the Securities or the Indenture or 
for any claim based on, in

                                     A-11

<PAGE>

respect of, or by reason of, such obligations or their creation.  Each Holder 
of Securities, by accepting a Security, waives and releases all such 
liability.  The waiver and release are part of the consideration for issuance 
of the Securities.  Such waiver may not be effective to waive liabilities 
under the federal securities laws and it is the view of the Commission that 
such a waiver is against public policy.

          16.  AUTHENTICATION.  This Security shall not be valid until 
authenticated by the manual signature of the Trustee or an authenticating 
agent.

          17.  ABBREVIATIONS.  Customary abbreviations may be used in the 
name of a Holder or an assignee, such as:  TEN COM (= tenants in common), TEN 
ENT (= tenants by the entireties), JT TEN (= joint tenants with right of 
survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A 
(= Uniform Gifts to Minors Act).

          18.  CUSIP NUMBERS.  Pursuant to a recommendation promulgated by 
the Committee on Uniform Security Identification Procedures, the Company has 
caused CUSIP numbers to be printed on the Securities and the Trustee may use 
CUSIP numbers in notices of redemption as a convenience to Holders.  No 
representation is made as to the accuracy of such numbers either as printed 
on the Securities or as contained in any notice of redemption and reliance 
may be placed only on the other identification numbers placed thereon.

          The Company will furnish to any Holder upon written request and 
without charge a copy of the Indenture.  Requests may be made to:

                                (Back of Note)

                  10 1/4% Senior Subordinated Notes due 2008


          Capitalized terms used herein shall have the meanings assigned to 
them in the Indenture referred to below unless otherwise indicated.

          1.   INTEREST.  Continental Resources, Inc., an Oklahoma 
corporation (the "COMPANY"), promises to pay interest on the principal amount 
of this Security at the rate of 10 1/4% per annum, which interest shall be 
payable in cash semiannually in arrears on each February 1 and August 1, or 
if any such day is not a Business Day, on the next succeeding Business Day 
(each an "INTEREST PAYMENT DATE"); PROVIDED that the first Interest Payment 
Date shall be February 1, 1999.  Interest on the Securities will accrue from 
the most recent date to which interest has been paid or, if no interest has 
been paid, from the date of original issuance.  Interest will be computed on 
the basis of a 360-day year comprised of twelve 30-day months.

          2.   METHOD OF PAYMENT.  On each Interest Payment Date the Company 
will pay interest to the Person who is the Holder of record of this Security 
as of the close of business on the January 15 or July 15 immediately 
preceding such Interest Payment Date, even if this Security is cancelled 
after such record date and on or before such Interest Payment Date, except as 
provided in Section 2.12 of the Indenture with respect to defaulted interest. 
Principal, premium, if any, and interest on this Security will be payable at 
the office or agency of the Company maintained for such purpose within The 
City and State of New York or, in the event the Securities do not remain in 
book-entry form, at the option of the Company, payment of interest may be 
made by check mailed to the Holder of this Security at its address set forth 
in the register of Holders of Securities; PROVIDED that all payments with 
respect to the Global Securities and Definitive Securities having an 
aggregate principal amount of $5.0 million or more the Holders of which have 
given wire transfer instructions to the Company at least 10 Business Days 
prior to the applicable payment date will be required to be made by wire 
transfer of immediately available funds to the accounts specified by the 
Holders thereof.  Such payment shall be in such coin or currency of the 
United States of America as at the time of payment is legal tender for 
payment of public and private debts.

          3.   PAYING AGENT AND REGISTRAR.  Initially, United States Trust 
Company of New York, the Trustee under the Indenture, will act as Paying 
Agent and Registrar.  The Company may change any Paying Agent or Registrar 
without notice to any Holder.  The Company or any Subsidiary Guarantor or any 
other of the Company's Subsidiaries may act in any such capacity.

          4.   INDENTURE.  The Company issued the Securities under an 
Indenture dated as of July 24, 1998 ("INDENTURE") among the Company, the 
Subsidiary Guarantors and the Trustee.  The 

                                      B-3

<PAGE>

terms of the Securities include those stated in the Indenture and those made 
part of the Indenture by reference to the Trust Indenture Act of 1939, as 
amended (15 U.S. Code Sections 77aaa-77bbbb).  The Securities are subject to 
all such terms, and Holders are referred to the Indenture and such Act for a 
statement of such terms.  The Securities are general unsecured obligations of 
the Company equal in an aggregate principal amount to $150,000,000 and will 
mature on August 1, 2008.

          The Securities are general unsecured senior subordinated 
obligations of the Company limited to $150,000,000 million aggregate 
principal amount (subject to Section 2.7 of the Indenture).  The aggregate 
principal amount of notes which may be authenticated and delivered under the 
Indenture, including the Securities, is limited to $300.0 million (subject to 
Section 2.7 of the Indenture).  This Security is one of the Exchange 
Securities referred to in the Indenture.  The Securities include the Initial 
Securities and any Exchange Securities issued in exchange for the Initial 
Securities pursuant to the Indenture and the Registration Rights Agreement.  
The Initial Securities and the Exchange Securities are treated as a single 
class of securities under the Indenture.  The Indenture imposes certain 
limitations on the incurrence of Indebtedness by the Company and its 
Restricted Subsidiaries, the payment of dividends and other distributions on 
the Capital Stock of the Company and its Restricted Subsidiaries, the 
purchase or redemption of Capital Stock of the Company and Capital Stock of 
such Restricted Subsidiaries, certain purchases or redemptions of 
Subordinated Indebtedness, the sale or transfer of assets and Capital Stock 
of Restricted Subsidiaries, the issuance or sale of Capital Stock of 
Restricted Subsidiaries, the Investments of the Company and its Subsidiaries 
and transactions with Affiliates.  In addition, the Indenture limits the 
ability of the Company and its Restricted Subsidiaries to restrict 
distributions and dividends from Restricted Subsidiaries.

          To guarantee the due and punctual payment of the principal, 
premium, if any, and interest on the Securities and all other amounts payable 
by the Company under the Indenture and the Securities when and as the same 
shall be due and payable, whether at maturity, by acceleration or otherwise, 
according to the terms of the Securities and the Indenture, the Subsidiary 
Guarantors have unconditionally guaranteed (and future Subsidiary Guarantors, 
together with the Subsidiary Guarantors, will unconditionally guarantee), 
jointly and severally, such obligations on a senior subordinated basis 
pursuant to the terms of the Indenture.

occasions, redeem up to 35% of the original aggregate principal amount of 
Securities at a redemption price equal to 110.250% of the principal amount 
thereof, plus accrued and unpaid interest, if any, thereon to the redemption 
date, with the net proceeds of sales of public common stock of the Company; 
PROVIDED that at least 65% of the original aggregate principal amount of 
Securities must remain outstanding immediately after the occurrence of such 
redemption; and PROVIDED, further, that any such redemption shall occur 
within 60 days after the date of the closing of the related sale of such 
common stock.  

          (c)  Notwithstanding the provisions of clause (a) of this Paragraph 
5, upon the occurrence of a Change of Control at any time on or prior to 
August 1, 2003, the Company may, at its option, redeem in whole but not in 
part, the Securities at a redemption price equal to 100% of the principal 
amount thereof, plus the Applicable Premium as of, and accrued but unpaid 
interest, if any, to, the date of redemption (subject to the right of Holders 
of record on the relevant record date to receive interest due on the relevant 
interest payment date) provided that such redemption shall be made no more 
than 90 days after the occurrence of a Change of Control.  The Company shall 
notify the Trustee and, by mail, the Holders of the Securities of its 
decision to redeem the Securities pursuant to this Paragraph 5(c) within 30 
days of the occurrence of a Change of Control.

          6.   MANDATORY REDEMPTION.

          Except as set forth in paragraph 7 below, the Company shall not be 
required to make mandatory redemption or sinking fund payments with respect 
to the Securities.

          7.   REPURCHASE AT OPTION OF HOLDER.

          (a)  Upon the occurrence of a Change of Control, if the Company 
does not redeem the Securities pursuant to paragraph 5(c), each Holder of 
Securities shall have the right to require the Company to repurchase all or 
any part (equal to $1,000 or an integral multiple thereof) of such Holder's 
Securities pursuant to the offer described below (the "Change of Control 
Offer") at an offer price in cash equal to 101% of the aggregate principal 
amount thereof plus accrued and unpaid interest, if any, thereon to the date 
of purchase (the "Change of Control Payment").  The right of the Holders of 
the Securities to require the Company to repurchase such Securities upon a 
Change of Control may not be waived by the Trustee without the approval of 
the Holders of the Securities required by Section 9.2 of the Indenture.  
Within 30 days following any Change of Control, the Company will mail a 
notice to each Holder describing the transaction or transactions that 
constitute the Change of Control and offering to repurchase Securities 
pursuant to the procedures required by the Indenture and described in such 
notice.  The Change of Control Payment shall be made on a business day not 
less than 30 days nor more than 60 days after such notice is mailed.  The 
Company and each Subsidiary Guarantor will comply with the requirements of 
Rule 14e-1 under the Exchange Act and any other securities laws and 
regulations thereunder to the extent such laws and regulations are applicable 
in connection with the repurchase of the Securities as a result of a Change 
of Control.

          (b)  If the Company or a Restricted Subsidiary consummates any 
Asset Sales permitted by the Indenture, when the aggregate amount of Excess 
Proceeds exceeds $15 million, the Company shall make an Asset Sale Offer to 
purchase the maximum principal amount of Securities and any other Pari Passu 
Indebtedness to which the Asset Sale Offer applies that may be purchased out 
of the Excess Proceeds, at an offer price in cash in an amount equal to, in 
the case of the Securities, 100% of the principal amount thereof, plus 
accrued and unpaid interest thereon to the date of purchase or, in the case 
of any Pari Passu Indebtedness, 100% of the principal amount thereof (or with 
respect to discount Pari Passu Indebtedness, the accreted value thereof) on 
the date of purchase, in each case, in accordance with the procedures set 
forth in Section 3.9 of the Indenture or the agreements governing the Pari 
Passu Indebtedness, as applicable.  To the extent that the aggregate 
principal amount (or accreted value, as the case may be) of Securities, and 
Pari Passu Indebtedness tendered pursuant to an Asset Sale Offer is less than 
the Excess Proceeds, the Company may use any remaining Excess Proceeds for 
general corporate purposes.  If the sum of (i) the aggregate principal amount 
of Securities surrendered by Holders thereof and (ii) the aggregate principal 
amount or accreted value, as the case may be, of Pari Passu Indebtedness 
surrendered by holders or lenders thereof exceeds the amount of Excess 
Proceeds, the Trustee and the trustee or other lender representative for the 
Pari Passu Indebtedness shall select the Securities and the other Pari Passu 
Indebtedness to be purchased on a pro rata basis, based on the aggregate 
principal amount (or accreted value, as applicable) thereof surrendered in 
such Asset

                                     B-6

<PAGE>

Sale Offer.  Upon completion of such Asset Sale Offer, the amount of Excess 
Proceeds shall be reset at zero.

          8.   NOTICE OF REDEMPTION.  Notice of redemption will be mailed at 
least 30 days but not more than 60 days before the redemption date to each 
Holder whose Securities are to be redeemed at its registered address. 
Securities in denominations larger than $1,000 may be redeemed in part but 
only in integral multiples of $1,000, unless all of the Securities held by a 
Holder are to be redeemed.  On and after the redemption date interest ceases 
to accrue on the aggregate principal amount of the Securities called for 
redemption.

          9.   DENOMINATIONS, TRANSFER, EXCHANGE.  The Securities may be 
issued initially in the form of one or more fully registered Global 
Securities.  The Securities may also be issued in registered form without 
coupons in minimum denominations of $1,000 and integral multiples of $1,000.  
The transfer of Securities may be registered and Securities may be exchanged 
as provided in the Indenture.  The Registrar and the Trustee may require a 
Holder, among other things, to furnish appropriate endorsements and transfer 
documents and the Company may require a Holder to pay any taxes and fees 
required by law or permitted by the Indenture.  The Company need not exchange 
or register the transfer of any Security or portion of a Security selected 
for redemption, except for the unredeemed portion of any Security being 
redeemed in part.  Also, it need not exchange or register the transfer of any 
Security for a period of 15 days before a selection of Securities to be 
redeemed or during the period between a record date and the corresponding 
Interest Payment Date.

          10.  PERSONS DEEMED OWNERS.  The registered Holder of a Security 
may be treated as its owner for all purposes.

          11.  AMENDMENT, SUPPLEMENT AND WAIVER.  Subject to certain 
exceptions, the Indenture or the Securities may be amended or supplemented 
with the consent of the Holders of at least a majority in aggregate principal 
amount of the Securities then outstanding (including, without limitation, 
consents obtained in connection with a purchase of, or the tender offer or 
exchange offer for, such Securities), and any existing Default or Event of 
Default under, or compliance with any provision of the Indenture or the 
Securities may be waived with the consent of the Holders of a majority in 
principal amount of the then outstanding Securities.  Without the consent of 
any Holder of a Security, the Indenture or the Securities may be amended or 
supplemented to cure any ambiguity, defect or inconsistency, to provide for 
uncertificated Securities in addition to or in place of certificated 
Securities, to provide for the assumption of the Company's obligations to 
Holders of the Securities in case of a merger or consolidation, to make any 
change that would provide any additional rights or benefits to the Holders of 
the Securities or that does not adversely affect the legal rights under the 
Indenture of any such Holder, to add guarantees with respect to the 
Securities or to secure the Securities or to comply with the requirements of 
the Commission in order to effect

                                    B-7

<PAGE>

or maintain the qualification of the Indenture under the Trust Indenture Act.

          12.  DEFAULTS AND REMEDIES.  Events of Default include:  (i) 
default for 30 consecutive days in the payment when due of interest on the 
Securities (whether or not prohibited by the provisions of Article 10 of the 
Indenture); (ii) default in payment when due of the principal of or premium, 
if any, on the Securities (whether or not prohibited by the provisions of 
Article 10 of the Indenture); (iii) failure by the Company or any Subsidiary 
Guarantor to comply with the provisions of Article 5 of the Indenture; (iv) 
failure by the Company for 30 consecutive days after notice from the Trustee 
or the Holders of at least 25% in aggregate principal amount of the 
Securities then outstanding to comply with the provisions of Sections 4.3, 
4.7, 4.8, 4.9, 4.10, 4.11, 4.12, 4.13, 4.14, 4.16, 4.17, 4.18 and 4.19 of the 
Indenture; (v) failure by the Company for 60 consecutive days after notice 
from the Trustee or the Holders of at least 25% in aggregate principal amount 
of the Securities then outstanding to comply with any of its other agreements 
or covenants in, or provisions of, this Security or in the Indenture; (vi) 
except as permitted by the Indenture, any Subsidiary Guarantee shall be held 
in any judicial proceeding to be unenforceable or invalid or shall cease for 
any reason to be in full force and effect or a Subsidiary Guarantor or any 
Person acting on behalf of a Subsidiary Guarantor, shall deny or disaffirm 
such Subsidiary Guarantor's obligations under its Subsidiary Guarantee; (vii) 
default under any mortgage, indenture or instrument under which there may be 
issued or by which there may be secured or evidenced any Indebtedness for 
money borrowed by the Company or any Restricted Subsidiary whether such 
Indebtedness or guarantee now exists, or is created after the date of the 
Indenture, which default (a) is caused by a failure to pay principal of such 
Indebtedness prior to the expiration of the grace period provided in such 
Indebtedness on the date of such default (a "Payment Default") or (b) results 
in the acceleration of such Indebtedness prior to its express maturity and, in 
each case, the principal amount of any such Indebtedness, together with the 
principal amount of any other such Indebtedness under which there is then 
existing a Payment Default or the maturity of which has been so accelerated, 
aggregates $10 million or more; (viii) a final non-appealable judgment or 
order or final non-appealable judgments or orders are rendered against the 
Company or any Restricted Subsidiary that remain unpaid or discharged for a 
period of 60 days and that require the payment in money, either individually 
or in an aggregate amount, that is more than $10 million; and (ix) certain 
events of bankruptcy or insolvency with respect to the Company or any 
Restricted Subsidiary.  If any Event of Default (other than an Event of 
Default described in clause (ix) above) occurs and is continuing, the Trustee 
or the Holders of at least 25% in principal amount of the then outstanding 
Securities may declare all the Securities to be due and payable immediately.  
Notwithstanding the foregoing, in the case of an Event of Default arising 
from certain events of bankruptcy or insolvency with respect to the Company 
or any Restricted Subsidiary, all outstanding Securities will become due and 
payable without further action or notice.  Holders of the Securities may not 

                                     B-8

<PAGE>

enforce the Indenture or the Securities except as provided in the Indenture.  
Subject to certain limitations, Holders of a majority in aggregate principal 
amount of the then outstanding Securities may direct the Trustee in its 
exercise of any trust or power.  The Trustee may withhold from Holders of the 
Securities notice of any continuing Default or Event of Default (except a 
Default or Event of Default relating to the payment of principal or interest) 
if it determines that withholding notice is in their interest.  The Holders 
of a majority in aggregate principal amount of the Securities then 
outstanding by notice to the Trustee may on behalf of the Holders of all of 
the Securities waive any existing Default or Event of Default and its 
consequences under the Indenture except a continuing Default or Event of 
Default in the payment of interest or premium on, or the principal of, the 
Securities.  The Company is required to deliver to the Trustee annually a 
statement regarding compliance with the Indenture, and the Company is 
required, within 5 Business days after becoming aware of any Default or Event 
of Default, to deliver to the Trustee a statement specifying such Default or 
Event of Default.

          13.  SUBORDINATION.  The Securities are subordinated to Senior Debt 
of the Company and the Subsidiary Guarantees are subordinated to Guarantor 
Senior Debt of the Subsidiary Guarantors.  To the extent provided in the 
Indenture, Senior Debt must be paid before the Securities may be paid and 
Guarantor Senior Debt of a Subsidiary Guarantor must be paid before a 
Subsidiary Guarantor may pay under its Subsidiary Guarantee.  The Company 
agrees, and each Holder by accepting a Security agrees, that the Indebtedness 
evidenced by the Securities, including, but not limited to, the payment of 
principal of, premium, if any, and interest on the Securities, and any other 
payment Obligation of the Company in respect of the Securities and the 
obligations of each Subsidiary Guarantor under its Subsidiary Guarantee are 
subordinated in right of payment, to the extent and in the manner provided in 
the Indenture, to the prior payment in full in cash of all Senior Debt of the 
Company and, in the case of a Subsidiary Guarantor, all Guarantor Senior Debt 
of such Subsidiary Guarantor (whether outstanding on the date hereof or 
hereafter created, incurred, assumed or guaranteed) and authorizes the 
Trustee to give effect and appoints the Trustee as attorney-in-fact for such 
purpose.

          14.  TRUSTEE DEALINGS WITH COMPANY.  The Indenture contains certain 
limitations on the rights of the Trustee, should it become a creditor of the 
Company, to obtain payment of claims in certain cases, or to realize on 
certain property received in respect of any such claim as security or 
otherwise.  The Trustee will be permitted to engage in other transactions; 
however, if it acquires any conflicting interest it must eliminate such 
conflict within 90 days, apply to the Commission for permission to continue 
or resign.

          15.  NO RECOURSE AGAINST OTHERS.  No director, officer, employee, 
incorporator or stockholder of the Company, as such, shall have any liability 
for any obligations of the Company under the Securities or the Indenture or 
for any claim based on, in

                                     B-9

<PAGE>

respect of, or by reason of, such obligations or their creation.  Each Holder 
of Securities, by accepting a Security, waives and releases all such 
liability.  The waiver and release are part of the consideration for issuance 
of the Securities.  Such waiver may not be effective to waive liabilities 
under the federal securities laws and it is the view of the Commission that 
such a waiver is against public policy.

          16.  AUTHENTICATION.  This Security shall not be valid until 
authenticated by the manual signature of the Trustee or an authenticating 
agent.

          17.  ABBREVIATIONS.  Customary abbreviations may be used in the 
name of a Holder or an assignee, such as:  TEN COM (= tenants in common), TEN 
ENT (= tenants by the entireties), JT TEN (= joint tenants with right of 
survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A 
(= Uniform Gifts to Minors Act).

          18.  CUSIP NUMBERS.  Pursuant to a recommendation promulgated by 
the Committee on Uniform Security Identification Procedures, the Company has 
caused CUSIP numbers to be printed on the Securities and the Trustee may use 
CUSIP numbers in notices of redemption as a convenience to Holders.  No 
representation is made as to the accuracy of such numbers either as printed 
on the Securities or as contained in any notice of redemption and reliance 
may be placed only on the other identification numbers placed thereon.

          The Company will furnish to any Holder upon written request and 
without charge a copy of the Indenture.  Requests may be made to:

                   FORM OF SUBSIDIARY GUARANTEE

          This Supplemental Indenture, dated as of [__________] (this 
"Supplemental Indenture" or "Guarantee"), among [name of future Subsidiary
Guarantor] (the "Guarantor"), Continental Resources, Inc. (together with its
successors and assigns, the "Company"), each other then existing Subsidiary
Guarantor under the Indenture referred to below, and United States Trust
Company of New York as Trustee under the Indenture referred to below.

                       W I T N E S S E T H:

          WHEREAS, the Company and the Trustee have heretofore executed and 
delivered an Indenture, dated as of July 24, 1998 (as amended, supplemented, 
waived or otherwise modified, the "INDENTURE"), providing for the issuance of 
an aggregate principal amount of $150.0 million of 10 1/4% Senior Subordinated 
Notes due 2008 of the Company (the "Securities";

          WHEREAS, Section 4.14 of the Indenture provides that the Company is 
required to cause each Restricted Subsidiary acquired or created by the 
Company or any Restricted Subsidiary to execute and deliver to the Trustee a 
Subsidiary Guarantee pursuant to which such Subsidiary Guarantor will 
unconditionally guarantee, jointly and severally with the other Subsidiary 
Guarantors, the full and prompt payment of the Securities pursuant to Article 
11 of the Indenture subject to the subordination provisions of Article 10 of 
the Indenture; and

          WHEREAS, pursuant to Section 9.1 of the Indenture, the Trustee and 
the Company are authorized to execute and deliver this Supplemental Indenture 
to amend the Indenture, without the consent of any Securityholder;

          NOW, THEREFORE, in consideration of the foregoing and for other 
good and valuable consideration, the receipt of which is hereby acknowledged, 
the Guarantor, the Company, the other Subsidiary Guarantors and the Trustee 
mutually covenant and agree for the equal and ratable benefit of the holders

CHASE SECURITIES INC.
270 Park Avenue, 4th floor
New York, New York  10017


Ladies and Gentlemen:

          Continental Resources, Inc., an Oklahoma corporation (the 
"COMPANY"), proposes to issue and sell, Continental Gas, Inc., an Oklahoma 
corporation and Continental Crude Co., an Oklahoma corporation (the 
"SUBSIDIARY GUARANTORS"), propose to guarantee and Chase Securities Inc. (the 
"INITIAL PURCHASER"), proposes to buy, upon the terms and subject to the 
conditions set forth in a purchase agreement dated July 21, 1998 (the 
"PURCHASE AGREEMENT"), $150,000,000 aggregate principal amount of the 
Company's 10 1/4% Senior Subordinated Notes due 2008 (the "NOTES"), which 
Notes shall be unconditionally guaranteed on a senior subordinated basis (the 
"SUBSIDIARY GUARANTEES" and, together with the Notes, the "SECURITIES"), by 
the Subsidiary Guarantors.  Capitalized terms used but not defined herein 
shall have the meanings given to such terms in the Purchase Agreement.  

          As an inducement to the Initial Purchaser to enter into the 
Purchase Agreement, and in satisfaction of a condition to the obligations of 
the Initial Purchaser to purchase the Securities under the Purchase 
Agreement, each of the Company and the Subsidiary Guarantors agrees with the 
Initial Purchaser, for the benefit of the holders (including the Initial 
Purchaser) of the Transfer Restricted Securities (as defined herein), the 
Exchange Securities (as defined herein) and the Private Exchange Securities 
(as defined herein) (collectively, the "HOLDERS"), as follows:

          1.   REGISTERED EXCHANGE OFFER.  The Company and the Subsidiary 
Guarantors shall (i) prepare and, not later than 60 days following the date 
of original issuance of the Securities (the "ISSUE DATE"), file with the 
Securities and Exchange Commission (the "COMMISSION") a registration 
statement (the "EXCHANGE OFFER REGISTRATION STATEMENT") on an appropriate 
form under the Securities Act of 1933, as amended (the "SECURITIES ACT") with 
respect to a proposed offer to the Holders of the 


<PAGE>

                                                                              2

Transfer Restricted Securities (the "REGISTERED EXCHANGE OFFER") to issue and 
deliver to such Holders, in exchange for the Transfer Restricted Securities, 
a like aggregate principal amount of debt securities of the Company (the 
"EXCHANGE NOTES") unconditionally guaranteed on a senior subordinated basis 
by the Subsidiary Guarantors (the "EXCHANGE GUARANTEE" and, together with the 
Exchange Notes, the "EXCHANGE SECURITIES") that are identical in all material 
respects to the Transfer Restricted Securities, except for the transfer 
restrictions relating to the Securities, (ii) use their respective reasonable 
best efforts to cause the Exchange Offer Registration Statement to become 
effective under the Securities Act no later than 150 days after the Issue 
Date and the Registered Exchange Offer to be consummated no later than 180 
days after the Issue Date and (iii) keep the Exchange Offer Registration 
Statement effective for not less than 30 days (or longer, if required by 
applicable law) after the date on which notice of the Registered Exchange 
Offer is first mailed to the Holders (such period being called the "EXCHANGE 
OFFER REGISTRATION PERIOD").  The Exchange Securities and the Private 
Exchange Securities (as defined below, if any) will be issued under the 
Indenture or an indenture (the "EXCHANGE SECURITIES INDENTURE") among the 
Company, the Subsidiary Guarantors and the Trustee or such other bank or 
trust company that is reasonably satisfactory to the Initial Purchaser, as 
trustee (the "EXCHANGE SECURITIES TRUSTEE"), such indenture to be identical 
in all material respects to the Indenture, except for the transfer 
restrictions relating to the Transfer Restricted Securities.  References 
herein to Securities, Exchange Securities, Transfer Restricted Securities and 
Private Exchange Securities (as defined herein) will be deemed to include the 
guarantees relating thereto.

          Upon the effectiveness of the Exchange Offer Registration Statement,
the Company and the Subsidiary Guarantors shall promptly commence the Registered
Exchange Offer, it being the objective of such Registered Exchange Offer to
enable each Holder electing to exchange Transfer Restricted Securities for
Exchange Securities (assuming that such Holder (a) is not an affiliate of the
Company or the Subsidiary Guarantors or an Exchanging Dealer (as defined herein)
not complying with the requirements of the next sentence, (b) is not the Initial
Purchaser with Securities that have the status of an unsold allotment in an
initial distribution, (c) acquires the Exchange Securities in the ordinary
course of such Holder's business and (d) has no arrangements or understandings
with any person to participate in the distribution of the Exchange Securities)
and to trade such Exchange Securities from and after their receipt without any
limitations or restrictions under the Securities Act and without material
restrictions under the securities laws of the several states of the United
States.  The Company, the Subsidiary Guarantors, the Initial Purchaser and each
Exchanging Dealer acknowledge that, pursuant to current interpretations by the
Commission's staff of Section 5 of the Securities Act, (i) each Holder that is a
broker-dealer electing to exchange Securities, acquired for its own account as a
result of market-

                                                                               3

making activities or other trading activities, for Exchange Securities (an 
"EXCHANGING DEALER"), is required to deliver a prospectus containing 
substantially the information set forth in Annex A hereto on the cover, in 
Annex B hereto in the "Exchange Offer Procedures" section and the "Purpose of 
the Exchange Offer" section and in Annex C hereto in the "Plan of 
Distribution" section of such prospectus in connection with a sale of any 
such Exchange Securities received by such Exchanging Dealer pursuant to the 
Registered Exchange Offer and (ii) if the Initial Purchaser elects to sell 
Private Exchange Securities acquired in exchange for Securities constituting 
any portion of an unsold allotment, it is required to deliver a prospectus 
containing the information required by Items 507 or 508 of Regulation S-K 
under the Securities Act and the Exchange Act ("REGULATION S-K").

          If, prior to the consummation of the Registered Exchange Offer, any 
Holder holds any Securities acquired by it that have, or that are reasonably 
likely to be determined to have, the status of an unsold allotment in the 
initial distribution of the Securities, or any Holder is not entitled to 
participate in the Registered Exchange Offer, the Company and the Subsidiary 
Guarantors shall, upon the request of any such Holder, simultaneously with 
the delivery of the Exchange Securities in the Registered Exchange Offer, 
issue and deliver to any such Holder, in exchange for the Securities held by 
such Holder (the "PRIVATE EXCHANGE"), a like aggregate principal amount of 
debt securities of the Company (the "PRIVATE EXCHANGE NOTES") unconditionally 
guaranteed on a senior subordinated basis by the Subsidiary Guarantors (the 
"PRIVATE EXCHANGE GUARANTEES" and, together with the Private Exchange Notes, 
the "PRIVATE EXCHANGE SECURITIES") that are identical in all material 
respects to the Exchange Securities, except for the transfer restrictions 
relating to such Private Exchange Securities.  The Private Exchange 
Securities will be issued under the same indenture as the Exchange 
Securities, and the Company shall use its reasonable best efforts to cause 
the Private Exchange Securities to bear the same CUSIP number as the Exchange 
Securities.

          In connection with the Registered Exchange Offer, the Company and 
the Subsidiary Guarantors shall:

          (a)  mail to each Holder a copy of the prospectus forming part of the
     Exchange Offer Registration Statement, together with an appropriate letter
     of transmittal and related documents;

          (b)  keep the Registered Exchange Offer open for not less than 30 days
     (or longer, if required by applicable law) after the date on which notice
     of the Registered Exchange Offer is first mailed to the Holders;

          (c)  utilize the services of a depositary for the Registered Exchange
     Offer with an address in the Borough of Manhattan, The City of New York;

          (d)  permit Holders to withdraw tendered Securities at any time prior
     to the close of business, New York City time, on the last business day on
     which the Registered Exchange Offer shall remain open; and

          (e)  otherwise comply in all respects with all laws that are
     applicable to the Registered Exchange Offer.

          As soon as practicable after the close of the Registered Exchange
Offer and any Private Exchange, as the case may be, the Company and the
Subsidiary Guarantors shall:

          (a)  accept for exchange all Securities tendered and not validly
     withdrawn pursuant to the Registered Exchange Offer and the Private
     Exchange;

          (b)  deliver to the Trustee for cancellation all Securities so
     accepted for exchange; and

          (c)  cause the Trustee or the Exchange Securities Trustee, as the case
     may be, promptly to authenticate and deliver to each Holder, Exchange
     Securities or Private Exchange Securities, as the case may be, equal in
     principal amount to the Securities of such Holder so accepted for exchange.

          The Company and the Subsidiary Guarantors shall use their 
respective reasonable best efforts to keep the Exchange Offer Registration 
Statement effective and to amend and supplement the prospectus contained 
therein in order to permit such prospectus to be used by all persons subject 
to the prospectus delivery requirements of the Securities Act for such period 
of time as such persons must comply with such requirements in order to resell 
the Exchange Securities; PROVIDED that the Company and the Subsidiary 
Guarantors shall make such prospectus and any amendment or supplement thereto 
available to any broker-dealer for use in connection with any resale of any 
Exchange Securities for a period of not less than 90 days after the 
consummation of the Registered Exchange Offer.

          The Indenture or the Exchange Securities Indenture, as the case may 
be, shall provide that the Transfer Restricted Securities, the Exchange 
Securities and the Private Exchange Securities shall vote and consent 
together on all matters as one class and that none of the Transfer Restricted 
Securities or the Exchange Securities will have the right to vote or consent 
as a separate class on any matter.

          Interest on each Exchange Security and Private Exchange Security 
issued pursuant to the Registered Exchange Offer and in the Private Exchange 
will accrue from the last interest payment date on which interest was paid on 
the Securities surrendered in exchange therefor or, if no interest has been 
paid on the Securities, from the Issue Date.

                                                                              5

          Each Holder participating in the Registered Exchange Offer shall be 
required to represent to the Company and the Subsidiary Guarantors that at 
the time of the consummation of the Registered Exchange Offer (i) any 
Exchange Securities to be received pursuant to the Registered Exchange Offer 
are being acquired in the ordinary course of the business of the person 
receiving such Exchange Securities, whether or not such person is the Holder, 
(ii) neither the Holder nor any such other person has any arrangement or 
understanding with any person to participate in the distribution of the 
Securities or the Exchange Securities within the meaning of the Securities 
Act, (iii) neither the Holder nor any such other person is an affiliate of 
the Company or of the Subsidiary Guarantors or, if it is such an affiliate, 
such Holder or such other person will comply with the registration and 
prospectus delivery requirements of the Securities Act to the extent 
applicable, (iv) if the Holder is not a broker-dealer, it is not engaged in, 
and does not intend to engage in, the distribution of the Exchange Securities 
and (v) if such person is an Exchanging Dealer, such person shall comply with 
the prospectus delivery requirements of the Securities Act.

          Notwithstanding any other provisions hereof, the Company and the 
Subsidiary Guarantors will ensure that (i) any Exchange Offer Registration 
Statement and any amendment thereto and any prospectus forming part thereof 
and any supplement thereto complies in all material respects with the 
Securities Act and the rules and regulations of the Commission thereunder, 
(ii) any Exchange Offer Registration Statement and any amendment thereto does 
not, when it becomes effective, contain an untrue statement of a material 
fact or omit to state a material fact required to be stated therein or 
necessary to make the statements therein not misleading and (iii) any 
prospectus forming part of any Exchange Offer Registration Statement, and any 
supplement to such prospectus, does not, as of the consummation of the 
Registered Exchange Offer, include an untrue statement of a material fact or 
omit to state a material fact necessary in order to make the statements 
therein, in the light of the circumstances under which they were made, not 
misleading.

          2.   SHELF REGISTRATION.  If (i) because of any change in law or 
applicable interpretations thereof by the Commission's staff the Company and 
the Subsidiary Guarantors are not permitted to effect the Registered Exchange 
Offer as contemplated by Section 1 hereof, or (ii) any Securities validly 
tendered pursuant to the Registered Exchange Offer are not exchanged for 
Exchange Securities within 150 days after the Issue Date, or (iii) the 
Initial Purchaser so requests with respect to Securities or Private Exchange 
Securities not eligible to be exchanged for Exchange Securities in the 
Registered Exchange Offer and held by it following the consummation of the 
Registered Exchange Offer, or (iv) any applicable law or interpretations do 
not permit any Holder to participate in the Registered Exchange Offer, or (v) 
any Holder that participates in the Registered Exchange Offer does not 
receive freely transferable Exchange Securities in exchange for tendered 
Securities (the obligation to 

<PAGE>

                                                                               6

comply with a prospectus delivery requirement being understood not to 
constitute a restriction on transferability), then the following provisions 
shall apply:

          (a)  The Company and the Subsidiary Guarantors shall use their 
respective reasonable best efforts to file as promptly as practicable (but in 
no event more than 45 days after so required or requested pursuant to this 
Section 2) with the Commission, and thereafter shall use their respective 
reasonable best efforts to cause to be declared effective, a shelf 
registration statement on an appropriate form under the Securities Act 
relating to the offer and sale of the Transfer Restricted Securities by the 
Holders thereof from time to time in accordance with the methods of 
distribution set forth in such registration statement (hereafter, a "SHELF 
REGISTRATION STATEMENT" and, together with any Exchange Offer Registration 
Statement, a "REGISTRATION STATEMENT"); PROVIDED, HOWEVER, that no Holder of 
Transfer Restricted Securities (other than the Initial Purchaser) shall be 
entitled to have Transfer Restricted Securities held by it covered by such 
Shelf Registration Statement unless such Holder agrees in writing to be bound 
by all the provisions of this Agreement applicable to such Holder.

          (b)  The Company and the Subsidiary Guarantors shall use their 
respective reasonable best efforts to keep the Shelf Registration Statement 
continuously effective in order to permit the prospectus forming part thereof 
to be used by Holders of Transfer Restricted Securities for a period ending 
on the earlier of (i) two years from the Issue Date or such shorter period 
that will terminate when all the Transfer Restricted Securities covered by 
the Shelf Registration Statement have been sold pursuant thereto and (ii) the 
date all of the Transfer Restricted Securities become eligible for resale 
without volume restrictions pursuant to Rule 144 under the Securities Act (in 
any such case, such period being called the "SHELF REGISTRATION PERIOD").  
The Company and the Subsidiary Guarantors shall be deemed not to have used 
their respective reasonable best efforts to keep the Shelf Registration 
Statement effective during the requisite period if they voluntarily take any 
action that would result in Holders of Transfer Restricted Securities covered 
thereby not being able to offer and sell such Transfer Restricted Securities 
during that period, unless such action is required by applicable law; 
PROVIDED HOWEVER, that the foregoing shall not apply to actions taken by the 
Company and the Subsidiary Guarantors in good faith and for valid business 
reasons (not including avoidance of their obligations hereunder), including, 
without limitation, the acquisition or divestiture of assets, so long as the 
Company and the Subsidiary Guarantors within 30 days thereafter comply with 
the requirements of Section 4(j) hereof. Any such period during which the 
Company and the Subsidiary Guarantors fail to keep the Shelf Registration 
Statement effective and usable for offers and sales of Transfer Restricted 
Securities is referred to as a "Suspension Period."  A Suspension Period 
shall commence on and include the date that the Company and the Subsidiary 
Guarantors give notice that the Shelf Registration Statement is no longer 

<PAGE>

                                                                              7

effective or the prospectus included therein is no longer usable for offers 
and sales of Transfer Restricted Securities and shall end on the date when 
each Holder of Transfer Restricted Securities covered by such registration 
statement either receives the copies of the supplemented or amended 
prospectus contemplated by Section 4(j) hereof or is advised in writing by 
the Company and the Subsidiary Guarantors that use of the prospectus may be 
resumed.  If one or more Suspension Periods occur, the two-year time period 
referenced above shall be extended by the aggregate of the number of days 
included in each such Suspension Period.

          (c)  Notwithstanding any other provisions hereof, the Company and 
the Subsidiary Guarantors will ensure that (i) any Shelf Registration 
Statement and any amendment thereto and any prospectus forming part thereof 
and any supplement thereto complies in all material respects with the 
Securities Act and the rules and regulations of the Commission thereunder, 
(ii) any Shelf Registration Statement and any amendment thereto (in either 
case, other than with respect to information included therein in reliance 
upon or in conformity with written information furnished to the Company and 
the Subsidiary Guarantors by or on behalf of any Holder specifically for use 
therein (the "HOLDERS' INFORMATION")) does not contain an untrue statement of 
a material fact or omit to state a material fact required to be stated 
therein or necessary to make the statements therein not misleading and (iii) 
any prospectus forming part of any Shelf Registration Statement, and any 
supplement to such prospectus (in either case, other than with respect to 
Holders' Information), does not include an untrue statement of a material 
fact or omit to state a material fact necessary in order to make the 
statements therein, in the light of the circumstances under which they were 
made, not misleading.

          3.   LIQUIDATED DAMAGES.  (a)  The parties hereto agree that the 
Holders of Transfer Restricted Securities will suffer damages if the Company 
or the Subsidiary Guarantors fail to fulfill their obligations under Section 
1 or Section 2, as applicable, and that it would not be feasible to ascertain 
the extent of such damages.  Accordingly, if (i) the applicable Registration 
Statement is not filed with the Commission on or prior to 60 days after the 
Issue Date, (ii) the Exchange Offer Registration Statement or the Shelf 
Registration Statement, as the case may be, is not declared effective within 
150 days after the Issue Date, (iii) the Registered Exchange Offer is not 
consummated on or prior to 180 days after the Issue Date, or (iv) the Shelf 
Registration Statement is filed and declared effective within 150 days after 
the Issue Date but shall thereafter cease to be effective (at any time that 
the Company and the Subsidiary Guarantors are obligated to maintain the 
effectiveness thereof) without being succeeded within 45 days by an 
additional Registration Statement filed and declared effective (each such 
event referred to in clauses (i) through (iv), a "REGISTRATION DEFAULT"), the 
Company will be obligated to pay liquidated damages to each Holder of 
Transfer Restricted Securities, during the period of one or more such 
Registration Defaults, in an 

<PAGE>

                                                                              8

amount equal to $0.192 per week per $1,000 principal amount of Transfer 
Restricted Securities held by such Holder until (i) the applicable 
Registration Statement is filed, (ii) the Exchange Offer Registration 
Statement is declared effective and the Registered Exchange Offer is 
consummated, (iii) the Shelf Registration Statement is declared effective or 
(iv) the Shelf Registration Statement again becomes effective, as the case 
may be.  Following the cure of all Registration Defaults, the accrual of 
liquidated damages will cease.  As used herein, the term "TRANSFER RESTRICTED 
SECURITIES" means (i) each Security until the date on which such Security has 
been exchanged for a freely transferable Exchange Security (the obligation to 
comply with a prospectus delivery requirement being understood not to 
constitute a restriction on transferability) in the Registered Exchange 
Offer, (ii) each Security or Private Exchange Security until the date on 
which it has been effectively registered under the Securities Act and 
disposed of in accordance with the Shelf Registration Statement or (iii) each 
Security or Private Exchange Security until the date on which it is 
distributed to the public pursuant to Rule 144 under the Securities Act or is 
saleable pursuant to Rule 144(k) under the Securities Act. Notwithstanding 
anything to the contrary in this Section 3(a), the Company shall not be 
required to pay liquidated damages to a Holder of Transfer Restricted 
Securities if such Holder failed to comply with its obligations to make the 
representations set forth in the penultimate paragraph of Section 1 or failed 
to provide the information required to be provided by it, if any, pursuant to 
Section 4(n).

          (b)  The Company shall notify the Trustee and the Paying Agent 
under the Indenture immediately upon the happening of each and every 
Registration Default.  The Company shall pay the liquidated damages due on 
the Transfer Restricted Securities by depositing with the Paying Agent (which 
may not be the Company for these purposes), in trust, for the benefit of the 
Holders thereof, prior to 10:00 a.m., New York City time, on the next 
interest payment date specified by the Indenture and the Securities, sums 
sufficient to pay the liquidated damages then due.  The liquidated damages 
due shall be payable on each interest payment date specified by the Indenture 
and the Securities to the record holder of the Transfer Restricted Securities 
entitled to receive the interest payment to be made on such date.  Each 
obligation to pay liquidated damages shall be deemed to accrue from and 
including the date of the applicable Registration Default.

          (c)  The parties hereto agree that the liquidated damages provided 
for in this Section 3 constitute a reasonable estimate of and are intended to 
constitute the sole damages that will be suffered by Holders of Transfer 
Restricted Securities by reason of the failure of (i) the Shelf Registration 
Statement or the Exchange Offer Registration Statement to be filed, (ii) the 
Shelf Registration Statement to remain effective or (iii) the Exchange Offer 
Registration Statement to be declared effective and the Registered Exchange 
Offer to be consummated, in each

                                                                              9

case, to the extent required by this Agreement.

          4.   REGISTRATION PROCEDURES.  In connection with any Registration 
Statement, the following provisions shall apply:

          (a)  The Company and the Subsidiary Guarantors shall (i) furnish to 
the Initial Purchaser, prior to the filing thereof with the Commission, a 
copy of the Registration Statement and each amendment thereof and each 
supplement, if any, to the prospectus included therein and shall use its 
reasonable best efforts to reflect in each such document, when so filed with 
the Commission, such comments as the Initial Purchaser may reasonably 
propose; (ii) include the information set forth in Annex A hereto on the 
cover, in Annex B hereto in the "Exchange Offer Procedures" section and the 
"Purpose of the Exchange Offer" section and in Annex C hereto in the "Plan of 
Distribution" section of the prospectus forming a part of the Exchange Offer 
Registration Statement, and include the information set forth in Annex D 
hereto in the Letter of Transmittal delivered pursuant to the Registered 
Exchange Offer; and (iii) if requested by the Initial Purchaser, include the 
information required by Items 507 or 508 of Regulation S-K, as applicable, in 
the prospectus forming a part of the Exchange Offer Registration Statement.

          (b)  Each of the Company and the Subsidiary Guarantors shall advise 
the Initial Purchaser, each Exchanging Dealer and the Holders (if applicable) 
and, if requested by any such person, confirm such advice in writing (which 
advice pursuant to clauses (ii)-(v) hereof shall be accompanied by an 
instruction to suspend the use of the prospectus until the requisite changes 
have been made):

          (i)  when any Registration Statement and any amendment thereto has
     been filed with the Commission and when such Registration Statement or any
     post-effective amendment thereto has become effective;

          (ii)  of any request by the Commission for amendments or supplements
     to any Registration Statement or the prospectus included therein or for
     additional information;

          (iii) of the issuance by the Commission of any stop order suspending
     the effectiveness of any Registration Statement or the initiation of any
     proceedings for that purpose; 

          (iv) of the receipt by the Company or the Subsidiary Guarantors of any
     notification with respect to the suspension of the qualification of the
     Securities or the Exchange Securities for sale in any jurisdiction or the
     initiation or threatening of any proceeding for such purpose; and

          (v)  of the happening of any event that requires the making of any
     changes in any Registration Statement or the 

<PAGE>

                                                                             10

     prospectus included therein in order that the statements therein (in 
     light of the circumstances in which made, in the case of the prospectus) 
     are not misleading and do not omit to state a material fact required to 
     be stated therein or necessary to make the statements therein not 
     misleading.

          (c)  The Company and the Subsidiary Guarantors will make every 
reasonable effort to obtain the withdrawal at the earliest possible time of 
any order suspending the effectiveness of any Registration Statement.

          (d)  The Company and the Subsidiary Guarantors will furnish to each 
Holder of Transfer Restricted Securities included within the coverage of any 
Shelf Registration Statement, upon request by such Holder, without charge, at 
least one conformed copy of such Shelf Registration Statement and any 
post-effective amendment thereto, including financial statements and 
schedules and, if any such Holder so requests in writing, all exhibits 
thereto (including those, if any, incorporated by reference).

          (e)  The Company and the Subsidiary Guarantors will, during the 
Shelf Registration Period, promptly deliver to each Holder of Transfer 
Restricted Securities included within the coverage of any Shelf Registration 
Statement, upon request by such Holder, without charge, as many copies of the 
prospectus (including each preliminary prospectus) included in such Shelf 
Registration Statement and any amendment or supplement thereto as such Holder 
may reasonably request; and the Company and the Subsidiary Guarantors consent 
to the use of such prospectus or any amendment or supplement thereto by each 
of the selling Holders of Transfer Restricted Securities in connection with 
the offer and sale of the Transfer Restricted Securities covered by such 
prospectus or any amendment or supplement thereto.

          (f)  The Company and the Subsidiary Guarantors will furnish to the 
Initial Purchaser and each Exchanging Dealer, and to any other Holder who so 
requests, without charge, at least one conformed copy of the Exchange Offer 
Registration Statement and any post-effective amendment thereto, including 
financial statements and schedules and, if the Initial Purchaser or 
Exchanging Dealer or any such Holder so requests in writing, all exhibits 
thereto (including those, if any, incorporated by reference).

          (g)  The Company and the Subsidiary Guarantors will, during the 
Exchange Offer Registration Period or the Shelf Registration Period, as 
applicable, promptly deliver to the Initial Purchaser, each Exchanging Dealer 
and any such other persons that are required to deliver a prospectus 
following the Registered Exchange Offer, without charge, as many copies of 
the final prospectus included in the Exchange Offer Registration Statement or 
the Shelf Registration Statement and any amendment or supplement thereto as 
the Initial Purchaser, Exchanging Dealer or other persons may reasonably 
request; and the Company and the Subsidiary Guarantors consent to the use of 
such prospectus or


<PAGE>


                                                                            11

any amendment or supplement thereto by the Initial Purchaser, Exchanging Dealer
or other persons, as applicable, as aforesaid.

          (h)  Prior to the effective date of any Registration Statement, the
Company and the Subsidiary Guarantors will use their respective reasonable best
efforts to register or qualify, or cooperate with the Holders of Securities,
Exchange Securities or Private Exchange Securities included therein and their
respective counsel in connection with the registration or qualification of, such
Securities, Exchange Securities or Private Exchange Securities for offer and
sale under the securities or blue sky laws of such jurisdictions as any such
Holder reasonably requests in writing and do any and all other acts or things
necessary or advisable to enable the offer and sale in such jurisdictions of the
Securities, Exchange Securities or Private Exchange Securities covered by such
Registration Statement; PROVIDED that the Company and the Subsidiary Guarantors
will not be required to qualify generally to do business in any jurisdiction
where they are not then so qualified or to take any action which would subject
them to general service of process or to taxation in any such jurisdiction where
it is not then so subject.

          (i)  The Company and the Subsidiary Guarantors will cooperate with the
Holders of Securities, Exchange Securities or Private Exchange Securities to
facilitate the timely preparation and delivery of appropriate certificates
representing Securities, Exchange Securities or Private Exchange Securities to
be sold pursuant to any Registration Statement free of any restrictive legends
and in such authorized denominations and registered in such names as the Holders
thereof may request in writing prior to sales of Securities, Exchange Securities
or Private Exchange Securities pursuant to such Registration Statement.

          (j)  If (i) any event contemplated by Section 4(b)(ii) through (v)
occurs during the period for which the Company and the Subsidiary Guarantors are
required to maintain an effective Registration Statement or (ii) any Suspension
Period remains in effect more than 30 days after the occurrence thereof, the
Company and the Subsidiary Guarantors will promptly prepare and file with the
Commission a post-effective amendment to the Registration Statement or a
supplement to the related prospectus or file any other required document so
that, as thereafter delivered to purchasers of the Securities, Exchange
Securities or Private Exchange Securities from a Holder, the prospectus will not
include an untrue statement of a material fact or omit to state a material fact
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading.

          (k)  Not later than the effective date of the applicable Registration
Statement, the Company and the Subsidiary Guarantors will provide a CUSIP number
for the Securities, Exchange Securities and Private Exchange Securities, as the
case may be, and provide the applicable trustee with certificates for 


<PAGE>


                                                                            12

the Securities, Exchange Securities or Private Exchange Securities, as the 
case may be, in a form eligible for deposit with The Depository Trust Company.

          (l)  The Company and the Subsidiary Guarantors will comply with all
applicable rules and regulations of the Commission and will make generally
available to their security holders as soon as practicable after the effective
date of the applicable Registration Statement an earning statement satisfying
the provisions of Section 11(a) of the Securities Act; PROVIDED that in no event
shall such earning statement be made generally available to their security
holders later than 45 days after the end of a 12-month period (or 90 days, if
such period is a fiscal year) beginning with the first month of the Company's or
the Subsidiary Guarantors' first fiscal quarter commencing after the effective
date of the applicable Registration Statement, which statement shall cover such
12-month period.

          (m)  The Company and the Subsidiary Guarantors will cause the
Indenture or the Exchange Securities Indenture, as the case may be, to be
qualified under the Trust Indenture Act as required by applicable law in a
timely manner.

          (n)  The Company and the Subsidiary Guarantors may require each Holder
of Transfer Restricted Securities to be registered pursuant to any Shelf
Registration Statement to furnish to the Company and the Subsidiary Guarantors
such information concerning the Holder and the distribution of such Transfer
Restricted Securities as the Company and the Subsidiary Guarantors may from time
to time reasonably require for inclusion in such Shelf Registration Statement,
and the Company and the Subsidiary Guarantors may exclude from such registration
the Transfer Restricted Securities of any Holder that fails to furnish such
information within a reasonable time after receiving such request.

          (o)  In the case of a Shelf Registration Statement, each Holder of
Transfer Restricted Securities to be registered pursuant thereto agrees by
acquisition of such Transfer Restricted Securities that, upon receipt of any
notice from the Company and the Subsidiary Guarantors pursuant to Section
4(b)(ii) through (v), such Holder will discontinue disposition of such Transfer
Restricted Securities until such Holder's receipt of copies of the supplemental
or amended prospectus contemplated by Section 4(j) or until advised in writing
(the "ADVICE") by the Company and the Subsidiary Guarantors that the use of the
applicable prospectus may be resumed.  If the Company and the Subsidiary
Guarantors shall give any notice under Section 4(b)(ii) through (v) during the
period that the Company and the Subsidiary Guarantors are required to maintain
an effective Registration Statement (the "EFFECTIVENESS PERIOD"), such
Effectiveness Period shall be extended by the number of days during such period
from and including the date of the giving of such notice to and including the
date when each seller of Transfer Restricted Securities covered by such
Registration

                                                                            13

Statement shall have received (x) the copies of the supplemental or amended 
prospectus contemplated by Section 4(j) (if an amended or supplemental 
prospectus is required) or (y) the Advice (if no amended or supplemental 
prospectus is required).

          (p)  In the case of a Shelf Registration Statement, the Company and
the Subsidiary Guarantors shall enter into such customary agreements (including,
if requested, an underwriting agreement in customary form) and take all such
other action, if any, as Holders of a majority in aggregate principal amount of
the Securities, Exchange Securities and Private Exchange Securities being sold
or the managing underwriters (if any) shall reasonably request in order to
facilitate any disposition of such Securities, Exchange Securities or Private
Exchange Securities pursuant to such Shelf Registration Statement.

          (q)  In the case of a Shelf Registration Statement, the Company and
the Subsidiary Guarantors shall (i) make reasonably available for inspection by
a representative of, and Special Counsel (as defined herein) acting for, Holders
of a majority in aggregate principal amount of the Securities, Exchange
Securities and Private Exchange Securities being sold and any underwriter
participating in any disposition of Securities, Exchange Securities or Private
Exchange Securities pursuant to such Shelf Registration Statement, at the
offices where normally kept, during reasonable business hours, all relevant
financial and other records, pertinent corporate documents and properties of the
Company and its subsidiaries and the Subsidiary Guarantors and (ii) use their
respective reasonable best efforts to have their officers, directors, employees,
accountants and counsel supply all relevant information reasonably requested by
such representative, Special Counsel or any such underwriter in connection with
such Shelf Registration Statement; PROVIDED, HOWEVER, that such persons shall
first agree in writing with the Company and the Subsidiary Guarantors that any
information that is in good faith designated by the Company and the Subsidiary
Guarantors in writing as confidential at the time of delivery of such
information shall be kept confidential by such persons, unless (i) disclosure of
such information is required by court or administrative order or is necessary to
respond to inquiries of regulatory authorities, (ii) disclosure of such
information is required by law (including any disclosure requirements pursuant
to federal securities laws in connection with the filing of such Shelf
Registration Statement or the use of any Prospectus), (iii) such information
becomes generally available to the public other than as a result of a disclosure
or failure to safeguard such information by such person or (iv) such information
becomes available to such person from a source other than the Company and its
subsidiaries and the Subsidiary Guarantors and such source is not bound by a
confidentiality agreement; and PROVIDED FURTHER each such person will also be
required to further agree in writing that (i) it will, upon learning that
disclosure of such information is sought in a court of competent jurisdiction,
if legally permitted, give notice to the Company and the Subsidiary Guarantors
and allow the Company and the Subsidiary Guarantors at 


<PAGE>


                                                                            14

their expense to undertake appropriate action to prevent disclosure of such 
information deemed confidential and (ii) it will not use such information in 
violation of any securities laws.

          (r)  In the case of a Shelf Registration Statement, the Company and
the Subsidiary Guarantors shall, if requested by Holders of a majority in
aggregate principal amount of the Securities, Exchange Securities and Private
Exchange Securities being sold, their Special Counsel or the managing
underwriters (if any) in connection with such Shelf Registration Statement, use
their respective reasonable best efforts to cause (i) their counsel to deliver
an opinion relating to the Shelf Registration Statement and the Securities,
Exchange Securities or Private Exchange Securities, as applicable, in customary
form, (ii) their officers to execute and deliver all customary documents and
certificates requested by such Holders of a majority in aggregate principal
amount of the Securities, Exchange Securities and Private Exchange Securities
being sold, their Special Counsel or the managing underwriters (if any) and
(iii) their respective independent public accountants to provide a comfort
letter or letters in customary form, subject to receipt of appropriate
documentation as contemplated, and only if permitted, by Statement of Auditing
Standards No. 72.

          5.   REGISTRATION EXPENSES.  The Company and the Subsidiary Guarantors
will bear all expenses incurred in connection with the performance of their
respective obligations under Sections 1, 2, 3 and 4 and the Company and the
Subsidiary Guarantors will reimburse the Initial Purchaser and the Holders for
the reasonable fees and disbursements of one firm of attorneys or counsel,
reasonably satisfactory to the Company and the Subsidiary Guarantors (in
addition to not more than one local counsel) chosen by the Holders of a majority
in aggregate principal amount of the Securities and the Exchange Securities to
be sold pursuant to each Registration Statement (the "SPECIAL COUNSEL") acting
for the Initial Purchaser or Holders in connection therewith.

          6.   INDEMNIFICATION.  (a)  In the event of a Shelf Registration
Statement or in connection with any prospectus delivery pursuant to an Exchange
Offer Registration Statement by the Initial Purchaser or an Exchanging Dealer,
as applicable, the Company and the Subsidiary Guarantors shall, jointly and
severally, indemnify and hold harmless each Holder (including, without
limitation, the Initial Purchaser or any such Exchanging Dealer), its
affiliates, their respective officers, directors, employees, representatives and
agents, and each person, if any, who controls such Holder within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act (collectively
referred to for purposes of this Section 6 and Section 7 as a Holder) from and
against any loss, claim, damage or liability, joint or several, or any action in
respect thereof (including, without limitation, any loss, claim, damage,
liability or action relating to purchases and sales of Securities, Exchange

                                                                            15

Securities or Private Exchange Securities), to which that Holder may become
subject, whether commenced or threatened, under the Securities Act, the Exchange
Act, any other federal or state statutory law or regulation, at common law or
otherwise, insofar as such loss, claim, damage, liability or action arises out
of, or is based upon, (i) any untrue statement or alleged untrue statement of a
material fact contained in any such Registration Statement or any prospectus
forming part thereof or in any amendment or supplement thereto or (ii) the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary in order to make the statements therein, in the
light of the circumstances under which they were made, not misleading, and shall
reimburse each Holder promptly upon demand for any legal or other expenses
reasonably incurred by that Holder in connection with investigating or defending
or preparing to defend against or appearing as a third party witness in
connection with any such loss, claim, damage, liability or action as such
expenses are incurred; PROVIDED, HOWEVER, that the Company and the Subsidiary
Guarantors shall not be liable in any such case to the extent that any such
loss, claim, damage, liability or action arises out of, or is based upon, an
untrue statement or alleged untrue statement in or omission or alleged omission
from any of such documents in reliance upon and in conformity with any Holders'
Information; and PROVIDED, FURTHER, that with respect to any such untrue
statement in or omission from any related preliminary prospectus, the indemnity
agreement contained in this Section 6(a) shall not inure to the benefit of any
Holder from whom the person asserting any such loss, claim, damage, liability or
action received Securities, Exchange Securities or Private Exchange Securities
to the extent that such loss, claim, damage, liability or action of or with
respect to such Holder results from the fact that both (A) a copy of the final
prospectus was not sent or given to such person at or prior to the written
confirmation of the sale of such Securities, Exchange Securities or Private
Exchange Securities to such person and (B) the untrue statement in or omission
from the related preliminary prospectus was corrected in the final prospectus
unless, in either case, such failure to deliver the final prospectus was a
result of non-compliance by the Company or the Subsidiary Guarantors with
Section 4(d), 4(e), 4(f) or 4(g).

          (b)  In the event of a Shelf Registration Statement, each Holder,
severally and not jointly, shall indemnify and hold harmless the Company, the
Subsidiary Guarantors, their affiliates, their respective officers, directors,
employees, representatives and agents, and each person, if any, who controls the
Company and the Subsidiary Guarantors within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act (collectively referred to for
purposes of this Section 6(b) and Section 7 as the Company and the Subsidiary
Guarantors), from and against any loss, claim, damage or liability, joint or
several, or any action in respect thereof, to which the Company and the
Subsidiary Guarantors may become subject, whether commenced or threatened, under
the Securities Act, the Exchange Act, any other federal or state statutory law
or regulation, at

                                                                            16

common law or otherwise, insofar as such loss, claim, damage, liability or 
action arises out of, or is based upon, (i) any untrue statement or alleged 
untrue statement of a material fact contained in any such Registration 
Statement or any prospectus forming part thereof or in any amendment or 
supplement thereto or (ii) the omission or alleged omission to state therein 
a material fact required to be stated therein or necessary in order to make 
the statements therein, in the light of the circumstances under which they 
were made, not misleading, but in each case, only to the extent that the 
untrue statement or alleged untrue statement or omission or alleged omission 
was made in reliance upon and in conformity with any Holders' Information, 
and shall reimburse the Company and the Subsidiary Guarantors for any legal 
or other expenses reasonably incurred by the Company and the Subsidiary 
Guarantors in connection with investigating or defending or preparing to 
defend against or appearing as a third party witness in connection with any 
such loss, claim, damage, liability or action as such expenses are incurred; 
PROVIDED, HOWEVER, that no such Holder shall be liable for any indemnity 
claims hereunder in excess of the amount of net proceeds received by such 
Holder from the sale of Securities, Exchange Securities or Private Exchange 
Securities pursuant to such Shelf Registration Statement.

          (c)  Promptly after receipt by an indemnified party under this Section
6 of notice of any claim or the commencement of any action, the indemnified
party shall, if a claim in respect thereof is to be made against the
indemnifying party pursuant to Section 6(a) or 6(b), notify the indemnifying
party in writing of the claim or the commencement of that action; PROVIDED,
HOWEVER, that the failure to notify the indemnifying party shall not relieve it
from any liability which it may have under this Section 6 except to the extent
that it has been materially prejudiced (through the forfeiture of substantive
rights or defenses) by such failure; and PROVIDED, FURTHER, that the failure to
notify the indemnifying party shall not relieve it from any liability which it
may have to an indemnified party otherwise than under this Section 6.  If any
such claim or action shall be brought against an indemnified party, and it shall
notify the indemnifying party thereof, the indemnifying party shall be entitled
to participate therein and, to the extent that it wishes, jointly with any other
similarly notified indemnifying party, to assume the defense thereof with
counsel reasonably satisfactory to the indemnified party.  After notice from the
indemnifying party to the indemnified party of its election to assume the
defense of such claim or action, the indemnifying party shall not be liable to
the indemnified party under this Section 6 for any legal or other expenses
subsequently incurred by the indemnified party in connection with the defense
thereof other than the reasonable costs of investigation; PROVIDED, HOWEVER,
that an indemnified party shall have the right to employ its own counsel in any
such action, but the fees, expenses and other charges of such counsel for the
indemnified party will be at the expense of such indemnified party unless (1)
the employment of counsel by the indemnified party has been authorized in
writing by the indemnifying party, (2) the 


<PAGE>


                                                                            17

indemnified party has reasonably concluded (based upon advice of counsel to 
the indemnified party) that there may be legal defenses to it or to other 
indemnified parties that are different from or in addition to those available 
to the indemnifying party, (3) a conflict or potential conflict exists (based 
upon advice of counsel to the indemnified party) between the indemnified 
party and the indemnifying party (in which case the indemnifying party will 
not have the right to direct the defense of such action on behalf of the 
indemnified party) or (4) the indemnifying party has not in fact employed 
counsel reasonably satisfactory to the indemnified party to assume the 
defense of such action within a reasonable time after receiving notice of the 
commencement of the action, in each of which cases the reasonable fees, 
disbursements and other charges of counsel will be at the expense of the 
indemnifying party or parties.  It is understood that the indemnifying party 
or parties shall not, in connection with any proceeding or related 
proceedings in the same jurisdiction, be liable for the reasonable fees, 
disbursements and other charges of more than one separate firm of attorneys 
(in addition to any local counsel) at any one time for all such indemnified 
party or parties.  Each indemnified party, as a condition of the indemnity 
agreements contained in Sections 6(a) and 6(b), shall use all reasonable 
efforts to cooperate with the indemnifying party in the defense of any such 
action or claim.  No indemnifying party shall be liable for any settlement of 
any such action effected without its written consent (which consent shall not 
be unreasonably withheld), but if settled with its written consent or if there 
be a final judgment for the plaintiff in any such action, the indemnifying 
party agrees to indemnify and hold harmless any indemnified party from and 
against any loss or liability by reason of such settlement or judgment.  No 
indemnifying party shall, without the prior written consent of the 
indemnified party (which consent shall not be unreasonably withheld), effect 
any settlement of any pending or threatened proceeding in respect of which 
any indemnified party is or could have been a party and indemnity could have 
been sought hereunder by such indemnified party, unless such settlement (i) 
does not contain an admission of fault or wrongdoing and (ii) includes an 
unconditional release of such indemnified party from all liability on claims 
that are the subject matter of such proceeding.

          7.   CONTRIBUTION.  If the indemnification provided for in Section 6
is unavailable or insufficient to hold harmless an indemnified party under
Section 6(a) or 6(b), then each indemnifying party shall, in lieu of
indemnifying such indemnified party, contribute to the amount paid or payable by
such indemnified party as a result of such loss, claim, damage or liability, or
action in respect thereof, (i) in such proportion as shall be appropriate to
reflect the relative benefits received by the Company and the Subsidiary
Guarantors from the offering and sale of the Securities, on the one hand, and a
Holder with respect to the sale by such Holder of Securities, Exchange
Securities or Private Exchange Securities, on the other, or (ii) if the
allocation provided by clause (i) above is not 


<PAGE>


                                                                            18

permitted by applicable law, in such proportion as is appropriate to reflect 
not only the relative benefits referred to in clause (i) above but also the 
relative fault of the Company and the Subsidiary Guarantors on the one hand 
and such Holder on the other with respect to the statements or omissions that 
resulted in such loss, claim, damage or liability, or action in respect 
thereof, as well as any other relevant equitable considerations.  The 
relative benefits received by the Company and the Subsidiary Guarantors on 
the one hand and a Holder on the other with respect to such offering and such 
sale shall be deemed to be in the same proportion as the total net proceeds 
from the offering of the Securities (before deducting expenses) received by 
or on behalf of the Company and the Subsidiary Guarantors as set forth in the 
table on the cover of the Offering Memorandum, on the one hand, bear to the 
total proceeds received by such Holder with respect to its sale of 
Securities, Exchange Securities or Private Exchange Securities, on the other. 
The relative fault shall be determined by reference to, among other things, 
whether the untrue or alleged untrue statement of a material fact or the 
omission or alleged omission to state a material fact relates to the Company 
and the Subsidiary Guarantors or information supplied by the Company and the 
Subsidiary Guarantors on the one hand or to any Holders' Information on the 
other, the intent of the parties and their relative knowledge, access to 
information and opportunity to correct or prevent such untrue statement or 
omission.  The parties hereto agree that it would not be just and equitable 
if contributions pursuant to this Section 7 were to be determined by PRO RATA 
allocation (even if the Holders were treated as one entity for such purpose) 
or by any other method of allocation that does not take into account the 
equitable considerations referred to herein.  The amount paid or payable by 
an indemnified party as a result of the loss, claim, damage or liability, or 
action in respect thereof, referred to above in this Section 7 shall be 
deemed to include, for purposes of this Section 7, any legal or other 
expenses reasonably incurred by such indemnified party in connection with 
investigating or defending any such action or claim.  Notwithstanding the 
provisions of this Section 7, an indemnifying party that is a Holder of 
Securities, Exchange Securities or Private Exchange Securities shall not be 
required to contribute any amount in excess of the amount by which the total 
price at which the Securities, Exchange Securities or Private Exchange 
Securities sold by such indemnifying party to any purchaser exceeds the 
amount of any damages which such indemnifying party has otherwise paid or 
become liable to pay by reason of any untrue or alleged untrue statement or 
omission or alleged omission.  No person guilty of fraudulent 
misrepresentation (within the meaning of Section 11(f) of the Securities Act) 
shall be entitled to contribution from any person who was not guilty of such 
fraudulent misrepresentation.  The Holders' obligations to contribute as 
provided in this Section 7 are several in proportion to their respective 
obligations and not joint.

          8.   RULES 144 AND 144A.    The Company and the Subsidiary Guarantors
shall use their respective reasonable best 


<PAGE>


                                                                            19

efforts to file the reports required to be filed by them under the Securities 
Act and the Exchange Act in a timely manner and, if at any time the Company 
and the Subsidiary Guarantors are not required to file such reports, they 
will, upon the written request of any Holder of Transfer Restricted 
Securities, make publicly available other information so long as necessary to 
permit sales of such Holder's securities pursuant to Rules 144 and 144A.  The 
Company and the Subsidiary Guarantors covenant that they will take such 
further action as any Holder of Transfer Restricted Securities may reasonably 
request, all to the extent required from time to time to enable such Holder 
to sell Transfer Restricted Securities without registration under the 
Securities Act within the limitation of the exemptions provided by Rules 144 
and 144A (including, without limitation, the requirements of Rule 
144A(d)(4)).  Upon the written request of any Holder of Transfer Restricted 
Securities, the Company and the Subsidiary Guarantors shall deliver to such 
Holder a written statement as to whether it has complied with such 
requirements. Notwithstanding the foregoing, nothing in this Section 8 shall 
be deemed to require the Company and the Subsidiary Guarantors to register 
any of their securities pursuant to the Exchange Act.

          9.   UNDERWRITTEN REGISTRATIONS.  If any of the Transfer Restricted
Securities covered by any Shelf Registration Statement are to be sold in an
underwritten offering, the investment banker or investment bankers and manager
or managers that will administer the offering will be selected by the Holders of
a majority in aggregate principal amount of such Transfer Restricted Securities
included in such offering, subject to the consent of the Company (which shall
not be unreasonably withheld or delayed), and such Holders shall be responsible
for all underwriting commissions and discounts in connection therewith.

          No person may participate in any underwritten registration hereunder
unless such person (i) agrees to sell such person's Transfer Restricted
Securities on the basis reasonably provided in any underwriting arrangements
approved by the persons entitled hereunder to approve such arrangements and (ii)
completes and executes all questionnaires, powers of attorney, indemnities,
underwriting agreements and other documents reasonably required under the terms
of such underwriting arrangements.

          10.  MISCELLANEOUS.  (a)  AMENDMENTS AND WAIVERS.  The provisions of
this Agreement may not be amended, modified or supplemented, and waivers or
consents to departures from the provisions hereof may not be given, unless the
Company has obtained the written consent of Holders of a majority in aggregate
principal amount of the Securities, Exchange Securities and Private Exchange
Securities, taken as a single class.  Notwithstanding the foregoing, a waiver or
consent to depart from the provisions hereof with respect to a matter that
relates exclusively to the rights of Holders whose Securities, Exchange
Securities or Private Exchange Securities are being sold pursuant to a
Registration Statement and that does not directly or 


<PAGE>


                                                                            20

indirectly affect the rights of other Holders may be given by Holders of a 
majority in aggregate principal amount of the Securities, Exchange Securities 
and the Private Exchange Securities being sold by such Holders pursuant to 
such Registration Statement.

          (b)  NOTICES. All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, first-class mail,
telecopier or air courier guaranteeing next-day delivery:

          (1)  if to a Holder, at the most current address given by such Holder
     to the Company in accordance with the provisions of this Section 10(b),
     which address initially is, with respect to each Holder, the address of
     such Holder maintained by the Registrar under the Indenture, with a copy in
     like manner to Chase Securities Inc.;

          (2)  if to the Initial Purchaser, initially at its address set forth
     in the Purchase Agreement; and

          (3)  if to the Company or the Subsidiary Guarantors, initially at the
     address of the Company and the Subsidiary Guarantors set forth in the
     Purchase Agreement.

          All such notices and communications shall be deemed to have been duly
given:  when delivered by hand, if personally delivered; one business day after
being delivered to a next-day air courier; five business days after being
deposited in the mail; and when receipt is acknowledged by the recipient's
telecopier machine, if sent by telecopier.

          The Initial Purchaser, the Company and the Subsidiary Guarantors, by
notice to the other, may designate additional or different addresses or telecopy
numbers for subsequent notices or communications.

          (c)  SUCCESSORS AND ASSIGNS.  This Agreement shall inure to the
benefit of and be binding upon the successors and assigns of each of the
parties, including, without the need for an express assignment or any consent by
the Company or the Subsidiary Guarantors thereto, subsequent Holders of
Securities, Exchange Securities or Private Exchange Securities.

          (d)  COUNTERPARTS.  This Agreement may be executed in any number of
counterparts (which may be delivered in original form or by telecopier) and by
the 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.

          (e)  DEFINITION OF TERMS.  For purposes of this Agreement, (a) the
term "business day" means any day on which the New York Stock Exchange, Inc. is
open for trading, (b) the term "subsidiary" has the meaning set forth in
Rule 405 under the 


 <PAGE>

                                                                              21

Securities Act and (c) except where otherwise expressly provided, the term 
"affiliate" has the meaning set forth in Rule 405 under the Securities Act. 

          (f)  HEADINGS.  The headings in this Agreement are for convenience of
reference only and shall not limit or otherwise affect the meaning hereof.

          (g)  GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

          (h)  REMEDIES.  In the event of a breach by the Company, and/or the
Subsidiary Guarantors, on the one hand, or by any Holder of Transfer Restricted
Securities, on the other hand, of any of their obligations under this Agreement,
each Holder of Transfer Restricted Securities or the Company or the Subsidiary
Guarantors, as the case may be, in addition to being entitled to exercise all
rights granted by law, including recovery of damages (other than the recovery of
damages for a breach by the Company and/or the Subsidiary Guarantors of their
obligations under Sections 1 or 2 hereof for which liquidated damages have been
paid pursuant to Section 3 hereof), will be entitled to specific performance of
its rights under this Agreement.  The Company, the Subsidiary Guarantors and
each Holder agree that monetary damages would not be adequate compensation for
any loss incurred by reason of a breach by it of any of the provisions of this
Agreement and hereby further agree that, in the event of any action for specific
performance in respect of such breach, it shall waive the defense that a remedy
at law would be adequate.

          (i)  NO INCONSISTENT AGREEMENTS.  The Company and each of the
Subsidiary Guarantors represents, warrants and agrees that (i) it has not
entered into, shall not, on or after the date of this Agreement, enter into any
agreement that is inconsistent with the rights granted to the Holders of
Transfer Restricted Securities in this Agreement or otherwise conflicts with the
provisions hereof, (ii) it has not previously entered into any agreement which
remains in effect granting any registration rights with respect to any of its
debt securities to any person and (iii) without limiting the generality of the
foregoing, without the written consent of the Holders of a majority in aggregate
principal amount of the then outstanding Transfer Restricted Securities, it
shall not grant to any person the right to request it to register any of its
securities under the Securities Act unless the rights so granted are not in
conflict or inconsistent with the provisions of this Agreement.

          (j)  NO PIGGYBACK ON REGISTRATIONS.  Neither the Company, the
Subsidiary Guarantors nor any of their security holders (other than the Holders
of Transfer Restricted Securities in such capacity) shall have the right to
include any securities of the Company and the Subsidiary Guarantors in any Shelf
Registration or Registered Exchange Offer other than Transfer Restricted
Securities.

          (k)  SEVERABILITY. The remedies provided herein are cumulative and not
exclusive of any remedies provided by law.  If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction to be
invalid, illegal, void or unenforceable, the remainder of the terms, provisions,
covenants and restrictions set forth herein shall remain in full force and
effect and shall in no way be affected, impaired or invalidated, and the parties
hereto shall use their reasonable best efforts to find and employ an alternative
means to achieve the same or substantially the same result as that contemplated
by such term, provision, covenant or restriction.  It is hereby stipulated and
declared to be the intention of the parties that they would have executed the
remaining terms, provisions, covenants and restrictions without including any of
such that may be hereafter declared invalid, illegal, void or unenforceable.

          (l)  JOINT AND SEVERAL LIABILITY. Each Subsidiary Guarantor, by its
execution and delivery of a counterpart to this Agreement, agrees that it shall
be jointly and severally liable for all obligations and liabilities of the
Company hereunder.

          Please confirm that the foregoing correctly sets forth the agreement
among the Company, each Subsidiary Guarantor and the Initial Purchaser.

          Each broker-dealer that receives Exchange Securities for its own 
account in exchange for Securities pursuant to the Registered Exchange Offer, 
where such Securities were acquired by such broker-dealer as a result of 
market-making activities or other trading activities, must acknowledge that 
it will deliver a prospectus in connection with any resale of such Exchange 
Securities. The Letter of Transmittal states that by so acknowledging and by 
delivering a prospectus, a broker-dealer will not be deemed to admit that it 
is an "underwriter" within the meaning of the Securities Act.  This 
prospectus, as it may be amended or supplemented from time to time, may be 
used by a broker-dealer in connection with resales of Exchange Securities 
received in exchange for Securities where such Securities were acquired by 
such broker-dealer as a result of market-making activities or other trading 
activities.  The Company and the Subsidiary Guarantors have agreed that, for 
a period of 90 days after the Expiration Date (as defined herein), it will 
make this prospectus available to any broker-dealer for use in connection 
with any such resale.  See "Plan of Distribution."

          Each broker-dealer that receives Exchange Securities for its own 
account in exchange for Securities, where such Securities were acquired by 
such broker-dealer as a result of market-making activities or other trading 
activities, must acknowledge that it will deliver a prospectus in connection

transactions in the over-the-counter market, in negotiated transactions, through

methods of resale, at market prices prevailing at the time of resale, at prices
related to such prevailing market prices or at negotiated prices.  Any such
resale may be made directly to purchasers or to or through brokers or dealers
who may receive compensation in the form of commissions or concessions from any
such broker-dealer or the purchasers of any such Exchange Securities.  Any

any such resale of Exchange Securities and any commission or concessions
received by any such persons may be deemed to be underwriting compensation under
the Securities Act.  The Letter of Transmittal states that, by acknowledging
that it will deliver and by delivering a prospectus, a broker-dealer will not be
deemed to admit that it is an "underwriter" within the meaning of the Securities
Act.

          For a period of 90 days after the Expiration Date the Company and the
Subsidiary Guarantors will promptly send additional copies of this prospectus
and any amendment or supplement to this prospectus to any broker-dealer that

    Re: 10 1/4% Senior Subordinated Notes due 2008
 
    Ladies and Gentlemen:
 
    We have acted as special counsel to Continental Resources, Inc. (the
"Company") in connection with the issuance and sale of $150,000,000 aggregate
principal amount of the Company's 10 1/4% Senior Subordinated Notes due 2008
(which are referred to herein as the "Old Notes") and the registration under the
Securities Act of 1933 of $150,000,000 aggregate principal amount of the
Company's 10 1/4% Senior Subordinated Notes due 2008 (the "New Notes"). The New
Notes are to be offered in exchange for all outstanding Old Notes (the "Exchange
Offer") as more fully set forth in the prospectus which forms are a part of the
Company's Registration Statement on Form S-4 (the "Registration Statement") with
which this opinion is being filed.
 
    In this connection we have examined the Company's Certificate of
Incorporation and Bylaws, minutes of certain meetings of the Company's Board of
Directors and the Indenture dated as of July 24, 1998 between the Company and
United States Trust Company of New York, as Trustee, governing the Old Notes and
the New Notes, and have made such other investigations of fact and law as we
deem necessary to render the opinions set forth herein.
 
    Based on the foregoing, we are of the opinion that the New Notes to be
exchanged for the Old Notes in the Exchange Offer, when issued in accordance
therewith, will be legally issued, fully paid and non-assessable and will be
binding obligations of the Company.
 
    The opinion expressed herein as to the New Notes constituting binding
obligations of the Company is subject to the exceptions that (1) enforcement may
be limited by bankruptcy, insolvency (including, without limitation, all laws
relating to fraudulent transfers), reorganization, moratorium or similar laws
affecting enforcement of creditors rights generally, and (2) enforcement is
subject to general principles of equity (regardless of whether enforcement is
considered a proceeding in equity or at law).
 
    We hereby consent to the reference to our firm in the Prospectus under the
caption "Legal Matters".
 
                                          Very truly yours,

                         PURCHASE AND SALE AGREEMENT

     This Agreement, dated March 28, 1998, is made by and between the 
signatory parties shown below under "Sellers" whose address is 201 Main 
Street, Fort Worth, Texas 76102 (hereinafter collectively called "Seller") 
and Continental Resources, Inc., whose address is P.O. Box 1032, Enid, 
Oklahoma 73702 (hereinafter called Buyer");

                            W I T N E S S E T H:

     WHEREAS, Buyer desires to purchase the Properties, as defined below, 
from Seller, and Seller desires to sell the same Properties to Buyer, subject 
to the terms and conditions of this Agreement.

     WHEREAS, It is the parties' intent that Buyer assume all responsibility 
and liability as provided herein for all matters relating to the Properties 
to be assigned.

     NOW, THEREFORE, In consideration of the mutual promises made herein and 
the benefits to be derived hereunder, and other good and valuable 
consideration, the sufficiency of which is hereby acknowledged, Seller and 
Buyer agree as follows:

     1.   PROPERTY TO BE SOLD AND PURCHASED.  Seller agrees to sell, and 
Buyer agrees to purchase, for the consideration herein set forth, and subject 
to the terms and provisions herein contained, the following described 
Properties, rights, and interests:

          (a)  All rights, titles, and interests of Seller in and to:  1) the
          oil, gas, and mineral leases described in Exhibit A hereto; and 2) the
          wells described in Exhibit B hereto;

          (b)  All rights, titles, and interests of Seller in and to, or
          otherwise derived from, all presently existing and valid oil, gas, and
          mineral unitization, pooling, and communitization agreements,
          declarations, and orders (including, without limitation, all units
          formed under orders, rules, regulations, or other official acts of any
          federal, state, or other authority having jurisdiction, and voluntary
          unitization agreements, designations, and declarations) relating to
          the properties described in subsection 1.(a) to the extent such
          rights, titles, and interests are attributable to the properties
          described in subsection 1.(a);

          (c)  All rights, titles, and interests of Seller in and to all
          presently existing and valid production sales contracts, operating
          agreements, and other agreements and contracts that relate to any of
          the properties described in subsections 1.a. and 1.b., to the extent
          such rights, titles, and interests are assignable and attributable to
          the properties described in subsections 1.(a) and 1.(b);

          (d)  All rights, titles, and interests of Seller in and to all
          rights-of-way, easements, surface leases, permits, and licenses
          appurtenant to the properties described in subsections 1.(a) and
          1.(b); and

          (e)  All rights, titles, and interests of Seller in and to all
          materials, supplies, machinery, equipment, improvements, and other
          personal property and fixtures (including, but not limited to,
          wellhead equipment, pumping units, flowlines, tanks, buildings,
          injection facilities, saltwater disposal facilities, compression
          facilities, gathering systems, and other equipment) located on the
          properties described in subsections 1.(a) and 1.(b) and used in
          connection with the exploration, development, operation, or
          maintenance thereof.

The properties and interests specified in subsections 1.(a), 1.(b), 1.(c), 
1.(d) and 1.(e) are herein sometimes collectively called the "Properties".  
The defined term "Properties" shall include seismic data, geological or 
geophysical data, including interpretations, environmental studies, or other 
similar data, or any interpretations thereof or other data or records related 
thereto.  Seller shall provide Buyer with such data Seller has in its files, 
excluding any interpretations, engineering 

                                       1
<PAGE>

reports and evaluations, Seller financial information and all data which 
Seller considers proprietary or confidential or that Seller cannot provide to 
Buyer without breaching, or risking a breach of, an agreement with a third 
party.

     2.   PURCHASE PRICE.  The unadjusted purchase price for the Properties 
shall be Eighty Six Million Five Hundred Thousand Dollars ($86,500,000.00), 
payable in United States dollars, (herein called the "Base Purchase Price"). 
The Base Purchase Price may be adjusted, as provided in Sections 7.(c), 11. 
and 16. hereof.  The Base Purchase Price, as so adjusted and as otherwise 
adjusted by mutual agreement of the parties herein, shall be called the 
"Purchase Price."

     3.   DEPOSIT.  Upon entering into this Agreement, as evidence of good 
faith, Buyer shall pay to Seller Eight Million Six Hundred Fifty Thousand 
Dollars ($8,650,000.00) hereinafter called the "Deposit".  If Buyer and 
Seller consummate the transaction contemplated hereby in accordance with the 
terms hereof, the Deposit shall be applied to the Base Purchase Price.  If 
Buyer and Seller do not consummate the transaction contemplated hereby 
because of a material default by Seller, in the absence of a default by 
Buyer, Seller shall return the Deposit to Buyer and shall, in addition, pay 
to Buyer the sum of Two Million Five Hundred Thousand Dollars ($2,500,000.00) 
as liquidated damages and not as a penalty.  Except as provided in Section 
12., if Buyer fails or refuses to consummate the transaction contemplated 
hereby, Seller shall retain the Deposit as liquidated damages and not as a 
penalty.  Buyer stipulates that Seller's damages in the event of Buyer's 
wrongful failure to close would be uncertain and that the amount of 
liquidated damages provided herein is reasonable.  Forfeiture of the Deposit 
as liquidated damages as provided herein shall be Seller's sole remedy at law 
or in equity for Buyer's failure to close as provided in this Agreement.  In 
no event shall the Deposit accrue interest.

     4.   ALLOCATION OF BASE PURCHASE PRICE.  Buyer has allocated the Base 
Purchase Price to the Properties by various categories.  These categories and 
the allocations thereto are shown on Exhibit E and have been made in good 
faith by Buyer and may be relied upon by Seller for all purposes of this 
Agreement.

     5.   SELLER'S REPRESENTATIONS.  Each of the individuals and entities 
comprising Seller represent to Buyer that:

          (a)  Each (other than natural persons) is a legal entity duly
          organized and legally existing under the laws of the State of Texas.

          obligations hereunder and has taken all necessary action to enter into
          this Agreement and perform its obligations hereunder.

          (c)  Execution and delivery of this Agreement, the consummation of the
          transaction contemplated hereby, and compliance with the terms hereof,
          will not result in any default under any agreement or instrument to
          which Seller, or any individual party thereof, is a party or by which
          the Properties are bound that would be material to this transaction. 
          Execution and delivery of this Agreement will not violate any
          contractual provision, order, writ, injunction, decree, statute, rule,
          or regulation applicable to Seller, or any individual party thereof,
          or to the Properties that would be material to this transaction,

          (iii)  Any approvals that must be obtained from governmental entities
          who are lessors under leases included in the Properties (or who

          obtained post-closing.

          (d)  This Agreement and the Assignment and Bill of Sale provided for
          in Section 14.(a)(i) hereof and any other documentation provided for
          herein to be executed by Seller, will, when executed and delivered,

          enforceable according to their terms, except as limited by bankruptcy
          or other laws applicable generally to creditor's rights and as limited
          by general, equitable principles.

          (e)  Except as disclosed on Exhibit D, there are no pending suits,
          actions, or other proceedings in which Seller is a party that
          materially affect the Properties (including, without limitation, any
          actions challenging or pertaining to Seller's title to any of the
          Properties) or affect the execution and delivery of this Agreement or

          hereunder.

          (c)  Buyer's execution and delivery of this Agreement, the
          consummation of the transaction contemplated hereby, and Buyer's
          compliance with the terms hereof, will not result in any default under
          any agreement or instrument to which Buyer is a party or by which the
          Properties are bound that would be material to this transaction.
          Buyer's execution and delivery of this Agreement will not violate any

          (d)  This Agreement and the Assignment and Bill of Sale provided for
          in Section 14.(a)(i) hereof and any other documentation provided for

               (including, without limitation, title files, division order

               PROVIDE TO BUYER OR THAT MAY BE PROVIDED BY OTHERS.

               (ii)  Seller shall make a good faith effort to give Buyer, or
               Buyer's authorized representatives, who have a legitimate need to
               know, at reasonable times and upon adequate notice to Seller,
               physical access to the Properties for the purpose of inspecting
               same.  Buyer recognizes that some of the Properties are operated
               by third parties and that Seller's ability to obtain access to
               such Properties, and the manner and extent of such access, is
               subject to the consent of such third parties.  Buyer agrees to
               comply fully with the rules, regulations, and any instructions
               issued by Seller or third party (where a Property is operated by
               such third party) regarding the actions of Buyer while upon,
               entering, or leaving the Properties.

               (iii)  If Buyer exercises rights of access under this Section or
               otherwise, or conducts examinations or inspections under this
               Section or otherwise, then (a) Buyer will be accompanied by
               Seller's representative at all times; (b) such access,
               examination, and inspection shall be at Buyer's sole risk, cost,
               and expense, and Buyer waives and releases all claims against
               Seller (its affiliates and their respective directors, officers,
               employees,attorneys, contractors, and agents) arising in any way
               therefrom or in any way connected therewith or arising in
               connection with the conduct of its directors, officers,
               employees, attorneys, contractors, and agents in connection
               therewith; and (c) BUYER SHALL RELEASE, INDEMNIFY, DEFEND, AND
               HOLD HARMLESS SELLER (AND

               ITS PARENT, SUBSIDIARY COMPANIES, AND OTHER AFFILIATES 
               AND THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES, 
               ATTORNEYS, CONTRACTORS, AND AGENTS) (HEREINAFTER COLLECTIVELY 
               REFERRED TO AS "SELLER GROUP") FROM ANY AND ALL CLAIMS, 
               ACTIONS, CAUSES OF ACTION, LIABILITIES, DAMAGES, LOSSES,COSTS, 
               OR EXPENSES (INCLUDING, WITHOUT LIMITATION, COURT COSTS AND 
               ATTORNEYS' FEES), OR LIENS OR ENCUMBRANCES FOR LABOR OR
               MATERIALS, ARISING OUT OF OR IN ANY WAY CONNECTED WITH SUCH
               ACCESS, EXAMINATION, AND INSPECTION.  THE FOREGOING RELEASE AND
               INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH CLAIMS, ACTIONS,
               CAUSES OF ACTION, LIABILITIES, DAMAGES, LOSSES, COSTS, OR
               EXPENSES ARISE OUT OF (i) NEGLIGENCE (INCLUDING SOLE NEGLIGENCE,
               SIMPLE NEGLIGENCE, CONCURRENT NEGLIGENCE, ACTIVE OR PASSIVE
               NEGLIGENCE, OR OTHERWISE, BUT EXPRESSLY NOT INCLUDING GROSS
               NEGLIGENCE OR WILLFUL MISCONDUCT) OF SELLER OR ANY OTHER
               INDEMNIFIED PARTY, OR (ii) STRICT LIABILITY.

          (b)  Seller shall continue to conduct its business in its ordinary
          course, and in accordance with all applicable ordinances, statutes,
          rules, and regulations of all local, state, and federal governments. 
          Seller shall not enter into or assume any contract or commitment which
          is not in the ordinary course of business as heretofore conducted in
          association with the Properties and shall carry on its business and
          operate the Properties as a reasonably prudent operator. Subject to
          existing contractual obligations, Seller shall not conduct, or commit
          to participate in, on behalf of Buyer, any operation on the
          Properties, or lands pooled or unitized therewith and shall not enter
          into a contract for the sale of crude oil from the Properties
          continuing in effect past the Effective Date without Buyer's prior
          written consent. However, Seller may take such steps and incur such
          expenses as it deems necessary in its sole opinion to deal with an
          emergency to safeguard any part of the Property without first
          consulting with Buyer.  As soon as possible after the emergency,
          Seller shall advise Buyer of such emergency action.  Except as set
          forth in this Agreement, Seller shall not sell, assign, transfer,
          mortgage, farmout, or otherwise dispose of, abandon, or encumber any
          material portion of the Properties.

          (c)  Seller shall use reasonable efforts, consistent with industry
          practices in transactions of this type, to identify, with respect to
          each material portion of the Properties, (i) all preferential rights
          to purchase that would apply to the transaction contemplated hereby
          and (ii) the parties holding such rights.  In attempting to identify
          the same, Seller shall not be obligated to go beyond its own records.
          Seller shall request from the parties so identified, and in accordance
          with the documents creating such rights, waivers of the preferential
          rights to purchase. Seller shall have no obligation hereunder other
          than to attempt to identify such preferential rights and to request
          such waivers.  Seller shall not be obligated to assure that such
          waivers are obtained.  Seller may tender to any party refusing to
          waive such a preferential right the interest covered by such right at
          a value as mutually agreed to by Buyer and Seller which shall be made
          in good faith, but in no event shall the value of a well exceed the
          value assigned to it by Ryder-Scott Company, an independent petroleum
          reservoir engineering company, in its recent Reserve Report dated
          January 14, 1998, prepared on behalf of Seller (hereinafter referred
          to as the "Ryder-Scott Report") using the present value (future net
          income before income taxes discounted at ten percent (10%)) of the
          total proved reserves. If Buyer and Seller are unable to agree on a
          value, the value for a well shall be determined as provided in Section
          11.(a)(ii) using the V/T = PVW/PVC equation for Properties falling in
          Categories A and B as shown on Exhibit E.  This value shall be used in
          determining the value of any 

                                       5
<PAGE>

          interest in a well covered by a preferential right to purchase.  
          The value shall be determined using the formula as provided in 
          Section 11.(a)(iii) for Properties falling in Category C where 
          F=Seller's net acres subject to a preferential right to purchase.  
          To the extent that such an interest is actually sold to a party 
          exercising such a preferential right, it shall be excluded from 
          the transaction contemplated hereby, and the Base Purchase Price 
          shall be reduced by the amount such party paid to Seller for such 
          interest unless the parties hereto agree otherwise.

          (d)  If applicable, as soon as practicable after the execution hereof,
          Buyer shall prepare and submit any necessary filings in connection
          with the transaction contemplated by this Agreement under the HSR Act.
          Buyer shall pay all filing fees in connection with such filing, shall
          request expedited treatment of such filing by the Federal Trade
          Commission ("FTC"), shall promptly make any appropriate or necessary
          subsequent or supplemental filings, and shall furnish to Seller copies
          of all filings made under the HSR Act at the same time they are filed
          with the FTC.  Seller shall cooperate with Buyer as to all filings
          required by the HSR Act.

          (e)  After both parties have executed this Agreement, Seller shall
          deliver to Buyer a copy of its "pay list" for each well listed on
          Exhibit B (which pay list shall include the name, address, social
          security number, and applicable share of proceeds of production, to
          the extent such information is contained in Seller's records, for each
          party to whom Seller is disbursing proceeds of production with respect
          to such property); and, a list of all parties for whom it is holding
          in suspense proceeds of production. Seller does not represent or
          warrant to Buyer the accuracy of the "pay lists" so delivered.

          (f)  At such time that all Asserted Defects (as hereinafter defined)
          have been fully resolved to the satisfaction of both Parties or if no
          Defects have been asserted by Buyer as of the Defect Notice Date (as
          hereinafter defined)upon Seller's receipt of Buyer's written
          confirmation and assurance that all Defects, if any, have been
          resolved and Buyer is prepared to close the transaction subject only
          to Seller's performance of its closing obligations as set forth in
          Section 14(a), Seller shall give Buyer and its accountants access to
          any and all accounting information in Seller's possession reasonably
          requested by Buyer for the preparation by Buyer, at its sole expense
          and risk, of pro-forma financial statements reflecting the financial
          performance of the Properties for the most recent three (3) calendar
          year(s). Buyer agrees that none of the information compiled for the
          purpose of this limited audit shall be used for the purpose of due
          diligence by Buyer or otherwise to assert any claim against Seller. 
          Seller shall have no responsibility whatever for the financial
          statements so prepared by Buyer.

     8.   DUE DILIGENCE REVIEWS.

          (a)  The term "Defect" as used in this Section shall mean any of the
          following:

               (i)  As of the Effective Date, Seller's ownership of a well
               listed on Exhibit B hereto either, (A) entitles Seller to receive
               a share of the oil, gas, and other hydrocarbons produced from, or
               allocated to, such well that is less than the share set forth on
               Exhibit B for such well in the columns headed "Net Revenue
               Interest (NRI)" and "Overriding Royalty Interest (ORI)",
               excepting any decreases caused by an increase in the landowner's
               royalty payable to the Federal and State Governments or pursuant
               to contractual obligations, including, without limitation,
               sliding scale overriding royalties, which are tied to amount of
               production, or as mandated by Federal and State statutes or as
               promulgated in the respective Federal and State Rules and
               Regulations; or, (B) causes Seller to bear a share of the cost of
               operating such well greater than the share set forth on Exhibit B
               for such well in the column headed "Working Interest (WI)"
               (without a proportionate increase in the share of 

                                       6
<PAGE>

               production to which Seller is entitled from such well);

               (ii)  Seller's ownership of a Property is subject to a lien other
               than (A) a lien that will be released at or before Closing, (B) a
               lien for taxes not yet delinquent, or (C) a lien under an
               operating agreement or similar agreement, to the extent the same
               relates to expenses incurred that are not yet due;

               (iii)  Seller's ownership of a Property is subject to a
               preferential right to purchase, unless a waiver of such right has
               been obtained with respect to the transaction contemplated hereby
               or an appropriate tender of the applicable interest has been made
               to the party holding such right and the period of time required
               for such party to exercise such right has expired without such
               party exercising such right;

               (iv)  Seller's ownership of a Property is subject to an
               imperfection in title that, if asserted, would cause a Defect, as
               defined in clause (i) above, to exist, and such imperfection in
               title normally would not be waived by reasonable and prudent
               persons engaged in the oil and gas business with knowledge of all
               the facts and their legal bearing and would materially impair or
               prevent Buyer from receiving payment from the purchasers of
               production, and would prevent the economic benefit Buyer could
               reasonably expect by acquiring the Properties;

               (v)  Seller's ownership of a non-producing Property is subject to
               an imperfection in title that, if asserted, would cause Seller's
               ownership as shown on Exhibit A to be less; and such imperfection
               in title normally would not be waived by reasonable and prudent
               persons engaged in the oil and gas business with knowledge of all
               the facts and their legal bearing and would materially prevent
               the economic benefit Buyer could reasonably expect by acquiring
               such Property.

          (b)  Buyer may conduct, to the extent it deems appropriate and at its
          sole risk and cost, such examinations and investigations as it may
          choose with respect to the Properties in order to determine whether
          "Defects" exist.  Unless waived, Buyer shall notify Seller in writing
          of such Defects as soon as they are identified, but no later than ten
          (10) days prior to the date upon which Closing is scheduled to occur
          pursuant to Section 14. [and not as extended pursuant to 14.(i) or
          14.(ii)] (hereinafter "Defect Notice Date").  Those Defects identified
          in such notice to Seller are herein called "Asserted Defects".  Such
          notification shall include a description of the Asserted Defect, the
          lease(s) described on Exhibit A affected by such Asserted Defect, the
          well(s) listed on Exhibit B to which the Asserted Defect relates, and
          all supporting documentation reasonably necessary fully to describe in
          detail the basis for the Asserted Defect; and, for each property,
          lease and applicable well, the size of any variance from "Net Revenue
          Interest (NRI)", "Overriding Royalty Interest (ORI)", or "Working
          Interest (WI)" set forth in Exhibit B that does or could result from
          such Asserted Defect.  Buyer hereby waives all Defects that it fails
          to identify to Seller as Asserted Defects on or before the Defect
          Notice Date.  If Buyer timely notifies Seller of Asserted Defects,
          Seller (i) shall have the right (but not the obligation) to attempt to
          cure such Asserted Defects prior to Closing, and (ii) shall also have
          the right (which may be exercised at any time before the Closing Date)
          to postpone the Closing by designating a new Closing Date not later
          than thirty (30) days after the Closing Date then existing, if Seller
          desires additional time to attempt to cure (including determining if
          it will attempt to cure) one or more Asserted Defects. In lieu of
          curing or attempting to cure an Asserted Defect, Seller may elect, at
          any time prior to Closing with respect to any Asserted Defect, to
          indemnify and hold Buyer harmless from and against any actual damages
          or loss (but specifically excluding consequential damages, special
          damages, or similar damages) Buyer may suffer as a result of a third
          party claim based on such Asserted Defect; provided, 

                                       7
<PAGE>

          unless Buyer consents, Seller may not so elect to indemnify Buyer 
          in lieu of curing such Asserted Defect(s) if the amount attributable 
          to such Asserted Defect(s) exceeds One Million Dollars($1,000,000.00).
          If Seller elects to indemnify Buyer as to an Asserted Defect, such 
          Asserted Defect will be treated under this Agreement as cured and, as 
          to such indemnified Asserted Defect, SELLER SHALL RELEASE, INDEMNIFY, 
          DEFEND, AND HOLD HARMLESS BUYER FROM AND AGAINST ANY AND ALL LOSS, 
          COST, DAMAGE, EXPENSE, OR LIABILITY WHATSOEVER, INCLUDING ATTORNEYS' 
          FEES, ARISING OUT OF THE ASSERTED DEFECT SELLER HAS ELECTED TO 
          INDEMNIFY (EXCEPT ANY CAUSED SOLELY BY THE GROSS NEGLIGENCE OR WILLFUL
          MISCONDUCT OF BUYER).

          (c)  Buyer shall have the right to make an environmental assessment of
          the Properties during the period beginning on the date of execution of
          this Agreement and ending on the Defect Notice Date.  Subject to the
          provisions regarding Buyer's rights to access under Section 7 hereof,
          Buyer and its agents shall have the right to enter upon the Properties
          and all buildings and improvements thereon, inspect the same, conduct
          soil and water tests and borings, and generally conduct such tests,
          examinations, investigations, and studies as Buyer may deem necessary
          or appropriate for the preparation of appropriate engineering and
          other reports in relation to the Properties and their physical and
          environmental condition. If Buyer proposes to undertake an
          environmental assessment, Buyer's proposed plan, the consultants to be
          used, and testing protocol must be approved by Seller before the work
          may begin.  Buyer agrees promptly to provide to Seller a copy of the
          environmental assessment, including any reports, data, and
          conclusions. Buyer shall keep all data and information acquired by
          such examinations and the results of all analyses of such data and
          information strictly confidential and shall not disclose same to any
          person or agency without the prior written approval of Seller. BUYER
          SHALL RELEASE, INDEMNIFY, DEFEND, AND HOLD HARMLESS THE SELLER GROUP
          FROM AND AGAINST ANY AND ALL LOSS, COST, DAMAGE, EXPENSE, OR LIABILITY
          WHATSOEVER, INCLUDING ATTORNEYS' FEES, ARISING OUT OF ANY
          ENVIRONMENTAL ASSESSMENT INCLUDING, BUT NOT LIMITED TO, INJURY TO OR
          DEATH OF PERSONS OR DAMAGE TO PROPERTY OCCURRING IN, ON, OR ABOUT THE
          PROPERTIES AS A RESULT OF SUCH ACTIVITIES (EXCEPT ANY SUCH INJURIES OR
          DAMAGES CAUSED SOLELY BY THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF
          ANY MEMBER OF THE SELLER GROUP).

          (d)  After the Defect Notice Date, Buyer shall be deemed to have
          inspected the Properties or waived its right to inspect the Properties
          for all purposes and satisfied itself as to their physical and
          environmental condition, both surface and subsurface.

     9.   ADVERSE ENVIRONMENTAL CONDITIONS.

          Seller represents to Buyer that to the best of its knowledge there are
          no environmental conditions, as hereinafter defined, existing as of
          the date hereof which Seller has not disclosed to Buyer.  Seller will
          advise Buyer of any Condition that Seller becomes aware of from the
          date hereof to the Closing Date.

          (a)  Buyer shall have until the Defect Notice Date to notify Seller of
          any material adverse environmental condition of the Properties which
          Buyer deems unacceptable and provide evidence of the condition to
          Seller.  An environmental condition is a material adverse
          environmental condition ("Condition") only if the following criteria
          are met:

               (i)  The environmental condition would have been required to be
               remediated on the Effective Date under the Environmental Laws;
               and,

                                       8
<PAGE>

               (ii)  The total cost to remediate all environmental conditions
               identified by Buyer affecting the Properties to the state
               required by the Environmental Laws is reasonably estimated to be
               at least $100,000.00.

          (b)  "Environmental Law" shall mean any federal, state, or local law,
          rule, regulation, order, or ordinance in effect as of the Effective
          Date of this Agreement pertaining to protecting the public health,
          welfare, and the environment.

          (c)  At Closing, Seller may elect any of the following provided a
          Condition exists:

               (i)  Decrease the Purchase Price by a mutually acceptable amount
               reflecting Seller's proportionate share, based on its working
               interest, of the cost reasonably estimated to remediate a
               Condition affecting the Properties to such a state as required by
               the Environmental Laws;

               (ii)  Remove the affected Properties from this Agreement and
               adjust the Base Purchase Price by an amount mutually agreed to by
               Seller and Buyer. If Buyer and Seller are unable to agree on an
               amount, the value of Properties falling in Categories A and B
               shall be determined as provided in Section 11.(a)(ii) using the
               V/T = PVW/PVC equation and an appropriate adjustment will be made
               using this value. The value of all affected Properties falling in
               Category C shall be determined using the formula in Section
               11.(a)(iii) where F=Seller's net acres affected by the Condition.

               (iii)  Remedy, or, if applicable, agree to indemnify, Buyer in
               accordance with Section 8(b); the Condition, as provided below.

          (d)  If option (c)(i) above is chosen, Buyer shall be responsible for
          any remediation and if the actual cost to remediate a Condition
          exceeds the amount of the estimate, Buyer shall pay the additional
          costs to remediate the Condition as required by applicable law.

          (e)  If option (c.)(iii). above is chosen, the following shall govern
          the remediation:

               (i)  Seller shall be responsible for all negotiations and
               contacts with federal, state, and local agencies and authorities
               with regard to the Condition or remediation. Buyer shall not make
               any independent contacts with any agency, authority, or other
               third party with respect to the Condition or remediation and will
               keep all information regarding the Condition and remediation
               confidential, except in each instance to the extent required by
               applicable law.

               (ii)  Seller shall remediate the Condition to the state agreed
               upon by Seller and Buyer, but in no event will Seller be required
               to remediate the Condition beyond the state required by the
               Environmental Laws.

               (iii)  Buyer will grant and warrant access to the affected
               Properties after Closing to Seller and third parties conducting
               assessments or remediation, to the extent and as long as
               necessary to conduct and complete the assessment or remediation
               work, to remove equipment and facilities, and to perform any
               other activities reasonably necessary in connection with
               assessment or remediation.

               (iv)  Buyer will use its best efforts not to interfere with
               Seller's ingress and egress or assessment or remediation
               activities.  Seller shall make reasonable 

                                       9
<PAGE>

               efforts to perform the work so as to minimize disruption to 
               Buyer's business activities and to the Properties.

               (v)  Seller shall continue remediation of the Condition until the
               first of the following occurs:

                    (1)  The appropriate governmental authorities provide
                    written notice to Seller or Buyer that no further
                    remediation of the Condition is required;

                    (2)  The parties agree that the Condition has been
                    remediated to the state required by the Environmental Laws
                    or as agreed by the parties.

                    Upon the occurrence of either (1) or (2) above, Seller shall
                    notify Buyer that remediation of the Condition is complete
                    and provide a copy of the notification described in (1)
                    above, if applicable.  Upon delivery of Seller's notice,
                    Seller shall be released from all liability and have no
                    further obligations under any provisions of this Agreement
                    in connection with a Condition.

               (vi)  Until Seller completes remediation of a Condition, Seller
               and Buyer will each notify the other of any pending or threatened
               claim, action, or proceeding by any authority or private party
               that relates to or would affect the environmental condition, the
               assessment, or the remediation of the affected Properties.

               (vii)  After Buyer takes over as operator, and before Seller has
               completed remediation of a Condition, if a leak, spill, or
               discharge of any material or substance ("Occurrence") occurs on
               the affected Properties, or any part of them, Buyer will promptly
               notify Seller and act promptly to minimize the effects of the
               Occurrence.  If a spill, leak, or discharge occurs and Seller
               determines that it may affect the area where Seller is conducting
               remediation or assessment, Buyer will hire a consultant (who must
               be acceptable to Seller) to assess the effect of the Occurrence
               on the environmental condition of the affected Properties, and
               the cost of Seller's remediation work and the cost of the
               additional work required as the result of the Occurrence.  Unless
               the Occurrence was caused solely by Seller, Buyer will be
               responsible for the incremental cost of remediating the impact of
               the Occurrence.  If Seller's remediation is expanded to
               incorporate remediation of the Occurrence, Buyer will promptly
               pay its share of costs and expenses to Seller as the work is
               performed, within thirty (30) days of receipt of invoices for the
               work (with supporting documentation).  Payments not made timely
               will bear interest at a rate of twelve percent (12%) per annum or
               the maximum lawful rate, whichever is less, compounded daily from
               the date of Buyer's receipt of the invoice until paid.

               If the cost of the additional work equals or exceeds the cost to
               complete the remediation which would have been incurred but for
               the Occurrence, Seller will pay Buyer the cost that would have
               been incurred by Seller to complete the remediation but for the
               Occurrence.  As consideration for this payment, Buyer will accept
               the environmental condition of the affected Properties as they
               exist on the date of the payment, assume full responsibility for
               remediating the affected Properties and related off-site
               contamination in accordance with this Agreement, and agrees to
               release, not to sue, indemnify, hold harmless, and defend Seller
               as to claims and liabilities arising from the Occurrence to the
               same extent as described in Sections 17., 18., and 20.

                                       10
<PAGE>

               (viii)  If Seller undertakes remediation as to any Properties in
               which Seller's ownership was less than 100%, and provided that
               the expense(s) incurred by Seller in such remediation are fair
               and reasonable, Buyer will bill the other working interest owners
               for their share of the remediation expenses.  Regardless of
               whether Buyer recoups any amount from the other working interest
               owners, Buyer will refund to Seller, within sixty (60) days of
               each Seller invoice, with documentation, any amounts expended by
               Seller over the amount attributable to Seller's former working
               interest share.

               (ix)  If Seller will assess or remediate the affected Properties
               after Closing, the Assignment and Bill of Sale or other
               recordable instrument will restate the rights and obligations of
               this section.

     10.  DISPOSAL OF MATERIALS, SUBSTANCES, AND WASTES; COMPLIANCE WITH LAW. 
Buyer will store, handle, transport, and dispose of or discharge all 
materials, substances, and wastes from the Properties (including produced 
water, drilling fluids, NORM, and other wastes), whether present before or 
after the Effective Date, in accordance with applicable local, state, and 
federal laws and regulations.  Buyer will keep records of the types, amounts, 
and location of materials, substances, and wastes that are stored, 
transported, handled, discharged, released, or disposed of onsite and 
offsite.  When any lease terminates, an interest in which has been assigned 
under this Agreement, Buyer will undertake additional testing, assessment, 
closure, reporting, or remedial action with respect to the Properties 
affected by the termination as is necessary to satisfy all local, state, or 
federal requirements in effect at that time and necessary to restore the 
Properties. Buyer shall assume full responsibility for the operations 
conducted pursuant to this Section 10. and agrees to release, not to sue, 
indemnify, hold harmless, and defend Seller as to all claims and liabilities 
arising therefrom to the same extent as described in Sections 17., 18., and 
20.

     11.  CERTAIN PRICE ADJUSTMENTS TO THE BASE PURCHASE PRICE.

          (a)  If Buyer presents Asserted Defects to Seller as a part of the due
          diligence reviews provided for in Section 8. above, and if Seller is
          unable or unwilling to cure such Asserted Defects prior to Closing, or
          if Buyer has elected to treat a Property affected by a casualty loss
          pursuant to Section 22. as if it were a Property affected by an
          Asserted Defect, then an appropriate adjustment to the Base Purchase
          Price to account for such Asserted Defects shall be made as follows:

               (i)  Buyer and Seller shall attempt to agree upon an appropriate
               adjustment to the Base Purchase Price to account for an Asserted
               Defect which Seller either is unable or unwilling to cure prior
               to Closing, and those Properties, or any part thereof, associated
               with the Asserted Defect shall be excluded from this Agreement
               and any rights of Buyer hereunder to such Properties shall
               terminate.

               (ii)  If Buyer and Seller are unable to agree upon an appropriate
               adjustment with respect to an Asserted Defect which affects
               Seller's interest in any Property falling in either Category A or
               B as shown on Exhibit E, adjustments shall be made as follows:

               Determine the value of all wells contained in the Unit in which
               the Property affected by the Asserted Defect falls by using the
               following equation and solve for V. "Unit" as used herein shall
               mean a drilling and spacing unit as determined by order or rule
               of the Wyoming Oil & Gas Conservation Commission or as otherwise
               permitted by law, or the Participating Area affected by the
               Asserted Defect.

                    V/T = PVW/PVC

                    T = Total amount ($) allocated to category containing Unit
               as shown 

                                       11

<PAGE>

               on Exhibit E.

                    PVW = BFIT PV @ 10% (Future net income before income taxes
               discounted at ten percent (10%)) of total proved reserves in all
               wells in Unit as contained in the Ryder-Scott Report.

                    PVC = BFIT PV @ 10% (Future net income before income taxes
               discounted at ten percent (10%)) of total proved reserves in all
               wells in Category as contained in the Ryder-Scott Report.

               The Base Purchase Price shall be adjusted by the absolute value
               of an amount using the following formula:

                    Adjustment = V X (1-[B/C])

                    V = Value of wells as determined above.

                    B = Correct net revenue interest for all wells in Unit
               including any overriding royalty interest.

                    C = Net revenue interest, including any overriding royalty
               interest, as shown on Exhibit B in all wells in Unit.

               (iii)  If an Asserted Defect affects Seller's interest in any
               Property falling in Category C and Buyer and Seller cannot
               mutually agree on an appropriate adjustment to the Base Purchase
               Price, adjustments shall be made using the following formula:

                    Adjustment = T X F/25,000

                    T = Total amount ($) allocated to Category C as shown on
               Exhibit E.

                    F = Seller's net acres affected by uncured Asserted Defect.

          (b)  If it is determined that Seller's interest in a well listed on
          Exhibit B is greater or lesser than the interest shown for such well
          under the columns headed "Net Revenue Interest (NRI)" and "Overriding
          Royalty Interest (ORI)" on Exhibit B, then Seller or Buyer may propose
          an increase or decrease, as applicable, in the Base Purchase Price, in
          which case such increase or decrease shall be handled in the same
          manner as provided above with respect to adjustments for Asserted
          Defects; provided that the party making such determination shall
          notify the other party of such adjustment on or before the Defect
          Notice Date.  Buyer shall have an affirmative obligation to disclose
          to Seller circumstances discovered by Buyer in its due diligence
          review that could result in an increase in the Base Purchase Price
          hereunder.  No increase in the Base Purchase Price will result from
          any royalty reduction resulting under the Federal Royalty Reduction
          Program.

          (c)  Notwithstanding the adjustments to be made pursuant to
          subsections 11.(a) and 11.(b) above, if such adjustments do not exceed
          $250,000 in the aggregate, no such adjustments shall be made and none
          of the Properties that would otherwise have been excluded pursuant to
          subsection 11.(a) above shall be excluded.  If the adjustments to be
          made pursuant to subsections 11.(a) and 11.(b) above, do exceed
          $250,000.00, the Base Purchase Price shall be adjusted according
          thereto.

     12.  CONDITIONS PRECEDENT TO BUYER'S OBLIGATIONS.  Buyer's obligations at
Closing under this Agreement are subject to each of the following conditions:

          (a)  Seller's representations under this Agreement shall be true and
          accurate in all 

                                       12
<PAGE>

          material respects as of the date when made and at Closing, except 
          as to changes specifically contemplated by this Agreement or consented
          to by Buyer in writing.

          (b)  Seller shall have performed and complied in all material respects
          with every covenant, agreement, and condition required by it under
          this Agreement prior to or at the Closing unless performance or
          compliance therewith shall have been waived by Buyer in writing.

          (c)  If applicable, Buyer and Seller shall have received approval from
          the FTC under the HSR Act of the transaction contemplated by this
          Agreement, or shall have received notification that the waiting period
          under such act has been terminated, or the waiting period under such
          act shall have expired.

          (d)  The Base Purchase Price increase or decrease resulting from the
          adjustments to be made pursuant to subsections 11.(a) and 11.(b) does
          not exceed twenty percent (20%) of the Base Purchase Price.

          (e)  On the Closing Date, no material suit, action, or other
          proceeding against Buyer shall be pending before any court or
          governmental agency seeking to restrain, prohibit, or obtain damages
          or other relief in connection with the consummation of the transaction
          contemplated by this Agreement.

If any such condition precedent to the obligations of Buyer under this Agreement
is not met as of the Closing Date, and if Buyer is not in material breach of its
obligations hereunder, this Agreement may be terminated at the option of Buyer. 
If Buyer thus terminates this Agreement, the Deposit shall be returned to Buyer
and the parties shall have no further obligations to one another hereunder
(other than the indemnifications contained in Sections 7.(a)(iii), 8.(c), and
21. hereof, which shall survive such termination).  Notwithstanding the
foregoing, if a condition set forth above, other than condition 12.(c) or
12.(d), is not met (and is asserted by Buyer as a failure of one of its
conditions of Closing), and if the reasons such condition is not met relate only
to some, but not all, of the Properties, failure of such condition to be met
may, at the option of either Buyer or Seller, be treated as an uncured Asserted
Defect and handled in accordance with the process set forth in Section 11.
above.

     13.  CONDITIONS PRECEDENT TO SELLER'S OBLIGATIONS.  Seller's obligations at
Closing under this Agreement are subject to each of the following conditions:

          (a)  Buyer's representations under this Agreement shall be true and
          accurate in all material respects as of the date when made and at
          Closing, except as to changes specifically contemplated by this
          Agreement or consented to by Seller.

          (b)  Buyer shall have performed and complied in all material respects
          with every covenant, agreement, and condition required by it under
          this Agreement prior to or at the Closing unless compliance therewith
          shall have been waived by Seller.

          (c)  If applicable, Buyer and Seller shall have received approval from
          the FTC under the HSR Act of the transaction contemplated by this
          Agreement, or shall have received notification that the waiting period
          under such act has been terminated, or the waiting period under such
          act shall have expired.

          (d)  The Base Purchase Price reduction or increase resulting from the
          adjustments to be made pursuant to subsections 11.(a) and 11.(b) does
          not exceed twenty percent (20%) of the Base Purchase Price.

          (e)  On the Closing Date, no material suit, action, or other
          proceeding against Seller shall be pending before any court or
          governmental agency seeking to restrain, prohibit, or obtain damages
          or other relief in connection with the consummation of the transaction
          contemplated by this Agreement.

                                       13
<PAGE>

If any such condition precedent to the obligations of Seller under this 
Agreement is not met as of the Closing Date, this Agreement may be terminated 
at the option of Seller.  If Seller terminates this Agreement because of 
Buyer's failure to fulfill condition 13.(a) or 13.(b), the Deposit shall not 
be returned to Buyer.  If Seller terminates this Agreement because of 
conditions 13.(c), 13.(d), or 13.(e), and Buyer is not in material default 
under this Agreement, the Deposit shall be returned to Buyer.  Thereafter, 
Seller and Buyer shall have no further obligations to one another hereunder 
(other than the indemnifications contained in Section 7.(a)(iii), 8.(c), and 
21. hereof, which shall survive such termination).

     14.  THE CLOSING.  If the conditions referred to in Section 12. of this 
Agreement (the "Conditions Precedent to Buyer's Obligations") and Section 13. 
of this Agreement (the "Conditions Precedent to Sellers Obligations") have 
been satisfied or waived, the consummation of the transaction contemplated 
hereby ("Closing") shall take place in the offices of Seller, at 201 Main 
Street, Fort Worth, Texas 76102, on May 14, 1998, at 10:00 a.m. Central 
Standard Time, or at such other date and time (i) as the Buyer and Seller may 
agree or, (ii) to which Seller may postpone the Closing pursuant to Section 
8.(b) hereof (such date and time herein called the "Closing Date"). It is 
provided however, that Seller shall not be permitted to extend the Closing 
Date pursuant to Section 8(b) beyond July 14, 1998, unless Buyer consents.  
At the Closing:

          (a)  Seller shall:

               (i)  Execute, acknowledge, and deliver to Buyer a conveyance of
               the Properties (the "Assignment and Bill of Sale"), which shall
               include a warranty of title as against claims arising by through
               or under Seller, and not otherwise, and in the form attached
               hereto as Exhibit C (with Exhibits A and B attached thereto),
               effective as of seven o'clock a.m., (7:00 a.m.) Mountain Standard
               Time on June 1, 1998, (herein called the "Effective Date");

               (ii)  Execute (and, where required, acknowledge) and deliver to
               Buyer forms of conveyance or assignment as required by the
               applicable authorities for transfers of interests in state or
               federal leases included in the Properties;

               (iii)  Execute and deliver to Buyer letters in lieu of transfer
               orders (or similar documentation), in form acceptable to both
               parties;

               (iv)  If Buyer requests, deliver to Buyer an affidavit or other
               certification (as permitted by the Internal Revenue Code of 1986,
               as amended) that Seller is not a "foreign person" within the
               meaning of Section 1445 (or similar provisions) of such code
               (i.e., Seller is not a non-resident alien, foreign corporation,
               foreign partnership, foreign trust, or foreign estate, as those
               terms are defined in such code and regulations promulgated
               thereunder);

               (v)  With respect to Properties operated by Seller and to the
               extent available, deliver to Buyer all requisite consents of
               non-operators under any operating agreement naming Buyer as
               successor operator; and copies of such requests for consent which
               were sent but not obtained prior to Closing;

               (vi)  Deliver to Buyer resignations of operator and/or Changes of
               Operator/Owner Forms properly executed on behalf of Seller for
               all Seller-operated wells acquired by Buyer; and, any other forms
               required by governmental authorities having jurisdiction which
               must be initiated by Seller to change the operator from Seller to
               Buyer as of the Effective Date; and,

               (vii)  Certificates in form and substance satisfactory to Seller,
               effective as of the Closing Date and executed by Seller's duly
               authorized officer, partner, or owner, as appropriate, to the
               effect that (1) Seller has all requisite corporate, 

                                       14
<PAGE>

               partnership, or other power and authority to sell the 
               Properties on the terms of this Agreement and to perform its 
               other obligations under this Agreement and has fulfilled all 
               corporate, partnership, or other prerequisites to closing 
               this transaction, and (2) each individual executing the 
               closing documents has the authority to act on behalf of 
               Seller.

               (viii)  Deliver possession of the Properties to Buyer as of the
               Effective Date.

          (b)  Buyer shall:

               (i)  Deliver to Seller, by wire transfer to an account designated
               by Seller in a bank located in the United States, an amount
               payable in United States dollars equal to the amount as set forth
               on the Closing Settlement Statement as provided for in Section
               16.(c) below;

               (ii)  Deliver to Seller, except to the extent waived by Seller:

          (A)  Evidence of compliance with the requirements of all laws, rules,
          and regulations relating to the transfer of operatorship from Seller
          to Buyer;

          (B)  Evidence of Buyer's bond coverage as required by all laws, rules,
          and regulations, or that a cash deposit, certificate of deposit,
          letter of credit, or some other permitted financial security has been
          accepted by the proper regulatory agency for each well requiring such
          coverage;

          (C)  Evidence of compliance with the requirements of all laws, rules,
          and regulations that Buyer is qualified to succeed to Seller's
          interest in the Properties; and,

          (D)  Certificates in form and substance satisfactory to Seller,
          effective as of the Closing Date and executed by Buyer's duly
          authorized officer, partner, or owner, as appropriate, to the effect
          that (1) Buyer has all requisite corporate, partnership, or other
          power and authority to purchase the Properties on the terms of this
          Agreement and to perform its other obligations under this Agreement
          and has fulfilled all corporate, partnership, or other prerequisites
          to closing this transaction, and (2) each individual executing the
          closing documents has the authority to act on behalf of Buyer.

          (iii)  Execute such forms and take such other steps as Seller may
          reasonably require to (A) succeed Seller with respect to the
          Properties under the rules and regulations of applicable authorities
          and (B) assume any and all liabilities of Seller with respect to the
          wells described on Exhibit B; and,

          (iv)  Take possession of the Properties.

     15.  AFTER CLOSING.  Within thirty (30) days after Closing, Seller shall
make available for delivery to Buyer at Seller's offices all of Seller's lease
files, abstracts and title opinions, division order files, production records,
well files, copies of accounting records (but not including general financial
accounting or tax accounting records), and other similar files and records that
directly relate to the Properties.  Notwithstanding the foregoing, Seller shall
not be required to deliver to Buyer materials that Seller considers proprietary
or confidential or that Seller legally cannot provide to Buyer without
breaching, or risking a breach of, confidentiality agreements with other
parties.  It is expressly understood that Buyer is not entitled to acquire any
records except as expressly provided in Section 1. hereof.  Seller may retain
such files, or copies thereof, or such information as it deems necessary for all
purposes, including but not limited to, preparing a Final Settlement Statement
as provided in Section 16., or for purposes of filing tax returns covering the
Properties.  Any files or materials retained by Seller after Closing pursuant
hereto, shall be sent to Buyer as soon as reasonably practicable after final
payment is made in accordance with the Final 

                                       15
<PAGE>

Settlement Statement.  Seller may, at its own expense, have access to and 
make copies of all, or any part thereof, of the files and records provided 
Buyer hereunder at reasonable times and upon reasonable notice during regular 
business hours for as long as the Properties remain in effect.

As to those wells which Seller is disbursing proceeds of production, Seller 
shall continue to collect proceeds of production as long as it remains 
operator and shall be responsible for making disbursements, in accordance 
with its normal procedures (and at normal times), of such proceeds of 
production so collected to the parties entitled to same, with any proceeds of 
production thereafter collected by Seller to be forwarded promptly to its 
successor as operator.

Provided Buyer succeeds Seller as operator, Buyer shall become responsible 
for all disbursements of proceeds of production and such disbursement 
activities shall be included in the matters that Buyer assumes and with 
respect to which Buyer indemnifies Seller under Section 17 below.

SELLER GIVES NO ASSURANCE HEREUNDER THAT BUYER SHALL SUCCEED SELLER AS 
OPERATOR OF ANY PROPERTY WHERE PARTIES OTHER THAN SELLER OWN INTERESTS IN 
SUCH PROPERTY. It is understood that in most (if not all) of the operating 
agreements affecting the Properties, Seller does not have the right to 
transfer operations of the leasehold interests subject thereto to Buyer.  
However, Seller shall use its best efforts to secure consent from all 
non-operators naming Buyer as Operator under such operating agreements prior 
to Closing, to be effective on the Closing Date and provided Closing takes 
place. After Closing, Buyer shall use its best efforts to comply with the 
terms of any operating agreements to name a successor operator thereunder for 
which Seller was unable to obtain prior to Closing. Upon obtaining consent 
from non-operators naming Buyer as successor operator, Seller and Buyer 
promptly shall file all forms required by any governmental agency having 
authority, to change the operator from Seller to Buyer.

Seller shall operate the Seller-operated Properties until the Effective Date 
and thereafter, if necessary, until such time as provided under the 
applicable operating agreement, plan of unitization, or law requires.  As 
soon as practicable thereafter, operations shall be turned over to, and 
become the responsibility of, Seller's successor as Operator To the extent 
Seller so operates any Property after the Effective Date, its obligations to 
Buyer with respect to such operations shall be no greater than those that it 
would have to a non-operator under the applicable operating agreement.  In 
the absence of an operating agreement, those terms and provisions contained 
in the AAPL 610 (1382 Revision) form Operating Agreement shall apply.  THE 
PARTIES RECOGNIZE THAT, UNDER SUCH AGREEMENTS AND SUCH FORM OF AGREEMENT, THE 
OPERATOR IS NOT RESPONSIBLE TO THE OTHER PARTIES THERETO FOR ITS OWN 
NEGLIGENCE AND HAS NO RESPONSIBILITY TO SUCH OTHER PARTIES OTHER THAN FOR 
GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.

As to all wells acquired by Buyer hereunder which Seller continues to operate 
on behalf of Buyer and for Buyer's account after the Effective Date because a 
successor operator has not been approved by the requisite governmental 
authority, or consent of non-operators has not been obtained, by mutual 
agreement or otherwise, Seller will be paid the producing well overhead rates 
shown in the operating agreement applicable to such wells and if there is no 
such established rate, Buyer shall pay Seller for its proportionate share 
thereof based upon the rate of five hundred dollars ($500.00) per month, or 
any part thereof, for each well.

     16.  CERTAIN ACCOUNTING ADJUSTMENTS TO THE PURCHASE PRICE.

          (a)  Appropriate adjustments to the Purchase Price shall be made
          between Buyer and Seller to reflect the following:

               (i)  All rights to proceeds, receipts, reimbursements, credits,
               and income attributable to the Properties and accruing before the
               Effective Time, as defined below, shall be the property of
               Seller.  All proceeds, receipts, credits, income, and charges
               attributable to the Properties acquired by Buyer hereunder and
               accruing on and after the Effective Time shall be the property 

                                       16
<PAGE>

               of Buyer.  As to Properties operated by Seller and purchased by
               Buyer hereunder and concerning accounts held in suspense, Seller
               will pay in full the royalty accounts that were suspended because
               the amount due is less than the statutory or contractual minimum
               for payment.  As to all other suspended accounts, if any, Seller
               shall transfer to its successor as operator all monies held in a
               suspended account which were received for production produced
               from or allocated to the Properties on and after the Effective
               Time.  As to proceeds received for production produced from or
               allocated to the Properties before the Effective Time and held in
               a suspense account at Buyer's option, Seller may either: 1)
               Retain the suspended amounts after Closing and, upon proof
               satisfactory to Seller, release the money to the proper party;
               or, 2) Transfer the suspended amounts to Buyer for future
               disbursement.  Once suspended amounts have been transferred to
               Buyer for future disbursement, Buyer agrees to be responsible for
               disbursing the suspended monies to the proper parties and shall
               release, indemnify, defend, and hold harmless the Seller Group
               from any and all claims, actions, causes of action, liabilities,
               damages, losses, costs, or expenses (including, without
               limitation, court costs and attorneys' fees), arising out of or
               in any way connected with making such disbursements, or failure
               to make a disbursement.

               (ii)  Seller shall be responsible for and pay (A) all charges and
               invoices for costs and expenses (including, without limitation,
               lease maintenance payments, drilling and operating expenses,
               capital expenditures, and overhead charges) accruing before the
               Effective Time and attributable to the Properties and (B)
               necessary royalty disbursements of proceeds realized from the
               sale of production produced from and allocated to the Properties
               before the Effective Time.  Buyer shall be responsible for
               payment of (C) all charges and invoices for costs and expenses
               (including, without limitation, lease maintenance payments,
               drilling and operating expenses, capital expenditures, and
               overhead charges) accruing on and after the Effective Time and
               attributable to the Properties acquired hereunder and (D)
               necessary royalty disbursements of proceeds realized from the
               sale of production produced from and allocated to the Properties
               acquired hereunder on and after the Effective Time.  All payments
               made by Seller for items under (C) above for which Buyer is
               responsible shall be reimbursed by Buyer.  Seller shall reimburse
               Buyer for all monies received by Seller from non-operators as
               payment of Seller's invoices for the operations of the wells
               described on Exhibit B for periods on and after the Effective
               Time.

               (iii)  Seller will be credited with an amount equal to the simple
               interest accrued on the Adjusted Purchase Price for the period
               beginning with the Closing Date and continuing through the
               Effective Date at seven percent (7%) simple annual interest
               calculated as follows:

                    INTEREST = Adjusted Purchase Price x number of days from 
                               closing to Effective Date x 7% divided by 365;

               The amount of interest credited to the Buyer will not exceed  
               $250,000.00 regardless of the above calculation, and further 
               such credit shall be only be applied if Closing occurs before 
               the Effective Date.

          (b)  In making such adjustments, the Parties agree that:

               (i) Seller will cause such oil storage facilities which store oil
               produced from the Properties to be gauged or strapped as of 7:00
               a.m. Mountain Standard Time on the Effective Date, herein also
               referred to as the Effective Time.  Seller also has caused the
               gas production meter charts (or if such do not exist, the sales
               meter charts) on the pipelines transporting gas production 

                                       17
<PAGE>

               from the Properties to be read as of the Effective Time. The 
               results of such gauging, strapping, or chart reading are 
               conclusive and shall be made available to Buyer.  The 
               production in such storage facilities or through such meters 
               on the gas pipelines as of the Effective Time shall be owned 
               by Seller; and, thereafter, production placed in such oil 
               storage facilities and gas production passing through the 
               aforesaid meters on the pipelines shall be owned by Buyer, 
               insofar as to the interests subject hereto as of Closing.
               
               (ii)  All ad valorem, severance, production and similar taxes
               applicable to the Properties shall be prorated between Seller and
               Buyer as of the Effective Date.  Therefore, all such taxes for
               1997 and prior years and for the portion of 1998 prior to the
               Effective Date levied against the Properties shall be borne and
               paid by Seller; and, all ad valorem and similar taxes for the
               remainder of 1998 and thereafter levied against the Properties
               shall be borne and paid by Buyer, irrespective if the amount
               levied is based on the previous year's production or any other
               basis.

               (iii)  Where Seller owns one-hundred percent (100%) of the
               working interest under a well and there is no overhead charge for
               determining the overhead expense to be charged to Buyer on and
               after the Effective Date, the overhead charge shall be deemed to
               be five hundred dollars ($500.00) per month, or any part thereof,
               per well.

               (iv)  Each party shall be responsible for its own income taxes.

          (c)  With respect to matters that can be determined as of Closing,
          Seller shall prepare, in accordance with the provisions of this
          Agreement and with generally accepted accounting principles, a
          statement (the "Closing Settlement Statement") setting forth each
          adjustment to the Base Purchase Price to the best of Seller's
          knowledge, whether upward or downward, as may be required in
          accordance herewith.  Seller shall submit to Buyer the Closing
          Settlement Statement no later than five (5) days prior to the Closing
          Date and shall afford Buyer access to Seller's records pertaining to
          the computation of the Closing Settlement Statement. Prior to the
          Closing, Buyer and Seller will agree upon the adjustments stated
          therein to be made to the Purchase Price, or will specify the
          adjustments to which there are differences and the adjustments to be
          omitted therefrom.  Only the agreed upon adjustments shall be taken
          into account in computing the adjustments to be made to the Purchase
          Price at Closing.  Final adjustments to the Purchase Price to be made
          hereunder shall be made within one hundred-twenty (120) days after the
          Closing Date for all matters other than Asserted Defects according to
          (d) hereinbelow as follows:

          (d)  As soon as practicable after the Closing, and in no event later
          than sixty (60) days following the Closing Date, Seller shall deliver
          to Buyer, in accordance with the provisions of this Agreement and with
          generally accepted accounting principles, a statement ("Final
          Settlement Statement") setting forth each adjustment under this
          Agreement which was not determined as of the Closing.  Within sixty
          (60) days after Buyer's receiving the Final Settlement Statement, the
          Parties shall agree upon the adjustments and payments stated in such
          Final Settlement Statement, and the net of such adjustments and
          payments shall be paid in cash to the appropriate Party by the other
          Party within five (5) days following agreement as to the Final
          Settlement Statement.  If the Parties fail to reach agreement as to
          all adjustment within said sixty (60) day period, the net amount of
          all undisputed adjustments shall be paid and any remaining disputed
          items shall be submitted for determination by a nationally recognized
          firm of public accountants selected by the parties, whose decision
          shall be final and binding.  The parties shall share equally the costs
          of such determination.

to each such damaged Property that Seller, in its sole discretion, elects not 
to repair, Buyer either may treat such Property as if it had an Asserted 
Defect or elect not to adjust the Purchase Price therefor.  If Buyer elects 
hereunder to treat the damaged Property as if it had an Asserted Defect, the 
procedure provided for in Section 11. shall apply to such Property, and all 
rights to insurance proceeds and claims against third parties related thereto 
shall belong to Seller.  If Buyer elects hereunder not to adjust the Purchase 
Price for such damaged Property, and if Seller is entitled to any claims 
under an insurance policy with respect to such damage, Seller shall either 
collect and pay over, or assign, such insurance claims to Buyer. Buyer shall 
then take title to such Property without reduction of the Purchase Price.  If 
Seller elects to repair a damaged Property, all rights to insurance proceeds 
and claims against third parties related thereto shall belong to Seller.

          (f)  PRIOR ENTIRE UNDERSTANDING/HEADINGS/GENDER.  This Agreement
          contains the entire understanding of the parties hereto with respect
          to the subject matter hereof and supersedes all prior agreements,

          respect to such subject matter, except as provided above with respect
          to any Confidentiality Agreement. The headings contained in this

          interest) and any other fees and taxes imposed on the Properties on
          and after the Effective Date, excluding Seller's income taxes, shall
          be 

                                       22
<PAGE>

          paid by Buyer.

          (i)  SUCCESSORS AND ASSIGNS.  This Agreement shall be binding on the
          parties hereto and their respective heirs, successors,
          representatives, and assigns.

          (j)  COUNTERPARTS.  This Agreement may be executed in any number of
          counterparts, each of which shall be deemed an original, but all of
          which shall constitute one (1) and the same instrument.  It shall not
          be necessary for both parties to sign the same counterpart.

          (k)  ENFORCEABILITY.  WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF
          LAW, THIS AGREEMENT SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH
          AND GOVERNED BY THE LAWS OF THE STATE OF TEXAS APPLICABLE TO CONTRACTS
          MADE AND TO BE PERFORMED ENTIRELY WITHIN SUCH STATE AND BY THE LAWS OF
          THE UNITED STATES OF AMERICA, EXCEPT THAT, TO THE EXTENT THE LAW OF A
          STATE IN WHICH THE PROPERTIES ARE LOCATED NECESSARILY GOVERNS, THE LAW
          OF SUCH STATE SHALL, TO SUCH EXTENT, APPLY TO THE PROPERTIES.

          (l)  PUBLICITY.  Prior to Closing, Buyer shall not issue any publicity
          or press release concerning this Agreement or the transaction
          contemplated hereby without the prior written consent of Seller
          unless, in the written opinion of legal counsel acceptable to Seller,
          such disclosure is required by applicable law or other applicable
          rules or regulations of any governmental authority or stock exchange
          and such publicity or press release contains no more than the minimum
          information necessary to comply therewith.

          (m)  USE OF SELLER'S NAME.  Buyer agrees that, as soon as practicable
          after the Closing, it shall remove or cause to be removed the names
          and signs used by Seller, and all variations and derivatives thereof
          and logos relating thereto from the Properties and shall not
          thereafter make any use whatsoever of such names, signs, and logos. 
          After Closing and as to those Properties Buyer has taken over as
          operator, Seller reserves the right of access to confirm that Buyer
          has removed Seller's name, signs, and logos.  If Seller is forced to
          remove its name, signs, and logos because Buyer has failed to do so,
          Seller shall charge its costs to Buyer and Buyer shall pay Seller's
          invoice within fifteen (15) days of receipt.

          (n)  SEVERABILITY.  If any term or provision of this Agreement is
          determined to be invalid, illegal, or incapable of being enforced by
          any rule of law or public policy, all other conditions and provisions
          of this Agreement shall nevertheless remain in full force and effect
          so long as the economic or legal substance of the transactions
          contemplated hereby is not affected in any material fashion to either
          Buyer or Seller.  Upon such determination that any term or other
          provision is invalid, illegal, or incapable of being enforced, Buyer
          and Seller shall negotiate in good faith to modify this Agreement so
          as to effect the original intent of the Parties as closely as possible
          in an acceptable manner to the end that the transactions contemplated
          hereby are fulfilled to the extent possible.

          (o)  RESERVATION OF CLAIMS.  Seller reserves all rights to claims,
          demands, cause of action, and lawsuits concerning the Properties
          against third parties that accrued before the Effective Date, whether
          discovered before or after the Effective Date, excluding any rights or
          claims associated with gas imbalances.

          (p)  DUTY TO DEFEND.  Where a party ("indemnitor") has agreed to
          indemnify, defend, and hold the other party ("indemnitee") harmless
          under this Agreement the indemnitee, at its sole option if it is the
          sole defendant, may elect to (a) manage its 

                                       23
<PAGE>

          own defense, in which event the indemnitor will reimburse the 
          indemnitee for all attorney's fees, court, and other costs 
          reasonably incurred in defending a claim, upon delivery to the 
          indemnitor of invoices for such expenses; or (b) allow the 
          indemnitor to be responsible for all aspects of defense.  If both 
          parties are defendants in a claim, they shall reasonably endeavor 
          to arrange for joint defense to minimize defense costs, but 
          failure to reach such agreement shall in no event eliminate or 
          limit any indemnity obligations hereunder.

          (q)  EXHIBITS.  All exhibits referenced herein and attached hereto are
          by reference incorporated into this Agreement.

     IN WITNESS WHEREOF, this Agreement is executed by the parties hereto on the

(1)  EBITDA represents earnings before interest expense, income taxes, 
depreciation, depletion, amortization and exploration expense, excluding 
proceeds from the litigation settlements. EBITDA is not a measure of cash 
flow as determined by generally accepted accounting principles ("GAAP"). 
EBITDA should not be considered as an alternative to, or more meaningful 
than, net income or cash flow as determined in accordance with GAAP or as an 
indicator of a company's operating performance or liquidity. Certain items 
excluded from EBITDA are significant components in understanding and 
assessing a company's financial performance, such as a company's cost of 
capital and tax structure, as well as historic costs of depreciable assets, 
none of which are components of EBITDA. The Company's computations of EBITDA 
may not be comparable to other similarly titled measures of other companies. 
The Company believes that EBITDA is a widely followed measure of operating 
performance and may also be used by investors to measure the Company's 
ability to meet future debt service requirements, if any.

     DELIVERY OF THIS LETTER OF TRANSMITTAL TO AN ADDRESS OTHER THAN AS SET 
FORTH ABOVE OR TRANSMISSION OF INSTRUCTIONS VIA A FACSIMILE TRANSMISSION TO A 
NUMBER OTHER THAN AS SET FORTH ABOVE WILL NOT CONSTITUTE A VALID DELIVERY.

     The undersigned acknowledges receipt of the Prospectus dated 
______________, 1998 (the "Prospectus") of Continental Resources, Inc. 
("Continental") which, together with this Letter of Transmittal (the "Letter 
of Transmittal"), constitutes Continental's offer (the "Exchange Offer") to 
exchange $1,000 principal amount of 10-1/4% Senior Subordinated Notes due 
2008 (the "New Notes") of Continental for each $1,000 principal amount of 
outstanding 10-1/4% Senior Subordinated Notes due 2008 (the "Old Notes") of 
Continental.  The terms of the New Notes are identical in all material 
respects (including, with respect to interest and upon redemption) to the 
terms of the Old Notes for which they may be exchanged pursuant to the 
Exchange Offer, except that the New Notes have been registered under the 
Securities Act of 1933, as amended, and, therefore, will not bear legends 
restricting the transfer thereof.

     The Exchange Offer is being made pursuant to the Registration Rights 
Agreement dated as of June 21, 1998 (the "Registration Rights Agreement"), 
and all Old Notes validly tendered will be accepted for exchange.  Any Old 
Notes not tendered will remain outstanding and continue to accrue interest, 
but will not retain any rights under the Registration Rights Agreement. 
Holders electing to have Old Notes exchanged 

<PAGE>

pursuant to the Exchange Offer will be required to surrender such Old Notes, 
together with the Letter of Transmittal, to the Exchange Agent at the address 
specified herein prior to the close of business on the Expiration Date.  
Holders will be entitled to withdraw their election, at any time prior to 
5:00 p.m., New York City time on the Expiration Date, by sending to the 
Exchange Agent at the address specified herein a facsimile transmission or 
letter setting forth the name of such Holder, the principal amount of Old 
Notes delivered for exchange and a statement that such Holder is withdrawing 
this election to have such Old Notes exchanged.

     The undersigned has checked the appropriate boxes below and signed this 
Letter of Transmittal to indicate the action the undersigned desires to take 
with respect to the Exchange Offer.

     PLEASE READ THE ENTIRE LETTER OF TRANSMITTAL AND THE PROSPECTUS 
CAREFULLY BEFORE CHECKING ANY BOX BELOW.

             PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY

Ladies and Gentlemen:

     Upon the terms and subject to the conditions of the Exchange Offer, the 
undersigned hereby tenders to Continental the above-described aggregate 
principal amount of Old Notes. Subject to, and effective upon, the acceptance 
for exchange of the Old Notes tendered herewith, the undersigned hereby 
exchanges, assigns and transfers to, or upon the order of, Continental all 
right, title and interest in and to such Old Notes. The undersigned hereby 
irrevocably constitutes and appoints the Exchange Agent as the true and 
lawful agent and attorney-in-fact of the undersigned (with full knowledge 
that said Exchange Agent acts as the agent of the undersigned in connection 
with the Exchange Offer) to cause the Old Notes to be assigned, transferred 
and exchanged. The undersigned represents and warrants that it has full power 
and authority to tender, exchange, assign and transfer the Old Notes and to 
acquire New Notes issuable upon the exchange of such tendered Old Notes, and 
that, when the same are accepted for exchange, Continental will acquire good 
and unencumbered title to the tendered Old Notes, free and clear of all 
liens, restrictions, charges and encumbrances and not subject to any adverse 
claim. The undersigned also warrants that it will, upon request, execute and 
deliver any additional documents deemed by Continental to be necessary or 
desirable to complete the exchange, assignment and transfer of tendered Old 
Notes or to transfer ownership of such Old Notes on the account books 
maintained by The Depository Trust Company.

     The Exchange Offer is subject to certain conditions as set forth in the 
Prospectus under the caption "The Exchange Offer -- Conditions of the 
Exchange Offer." The undersigned recognizes that as a result of these 
conditions (which may be waived, in whole or in part, by Continental) as more 
particularly set forth in the Prospectus, Continental may not be required to 
exchange any of the Old Notes tendered hereby and, in such event, the Old 
Notes not exchanged will be returned to the undersigned at the address shown 
below the signature of the undersigned.

     By tendering, each Holder of Old Notes represents to Continental that 
(i) the New Notes acquired pursuant to the Exchange Offer are being obtained 
in the ordinary course of business of the person receiving such New Notes, 
whether or not such person is such Holder, (ii) neither the Holder of Old 
Notes nor any such other person has an arrangement or understanding with any 
person to participate in the distribution of such New Notes, (iii) if the 
Holder is not a broker-dealer or is a broker-dealer but will not receive New 
Notes for its own account in exchange for Old Notes, neither the Holder nor 
any such other person is engaged in or intends to participate in a 
distribution of the New Notes and (iv) neither the Holder nor any such other 
person is an "affiliate" of Continental within the meaning of Rule 405 under 
the Securities Act of 1933, as amended (the "Securities Act") or, if such 
Holder is an "affiliate," that such Holder will comply with the registration 
and prospectus delivery requirements of the Securities Act to the extent 
applicable. If the tendering Holder is a broker-dealer (whether or not it is 
also an "affiliate" of Continental within the meaning of Rule 405 under the 
Securities Act) that will receive New Notes for its own account in exchange 
for Old Notes, it acknowledges that it will deliver a prospectus meeting the 
requirements of the Securities Act in connection with any resale of such New 
Notes. By acknowledging that it will deliver and by delivering a prospectus 
meeting the requirements of the Securities Act in connection with any resale 
of such New Notes, the undersigned is not deemed to admit that it is an 
"underwriter" within the meaning of the Securities Act.

     All authority herein conferred or agreed to be conferred shall survive 
the death, bankruptcy or incapacity of the undersigned and every obligation 
of the undersigned hereunder shall be binding upon the 

                                      -4-
<PAGE>

heirs, personal representatives, executors, administrators, successors, 
assigns, trustees in bankruptcy and other legal representatives of the 
undersigned. Tendered Old Notes may be withdrawn at any time prior to 5:00 
p.m., New York City Time on the Expiration Date.

     Certificates for all New Notes delivered in exchange for tendered Old 
Notes and any Old Notes delivered herewith but not exchanged, in each case 
registered in the name of the undersigned, shall be delivered to the 
undersigned at the address shown below the signature of the undersigned.

                                 INSTRUCTIONS

                    FORMING PART OF THE TERMS AND CONDITIONS
                             OF THE EXCHANGE OFFER

     1.   DELIVERY OF THIS LETTER OF TRANSMITTAL AND CERTIFICATES. 
Certificates for all physically delivered Old Notes, as well as a properly 
completed and duly executed copy of this Letter of Transmittal or facsimile 
thereof, and any other documents required by this Letter of Transmittal, must 
be received by the Exchange Agent at any of its addresses set forth herein on 
or prior to the Expiration Date.

     THE METHOD OF DELIVERY OF OLD NOTES, THIS LETTER OF TRANSMITTAL AND ALL 
OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND RISK OF 
THE HOLDER AND, EXCEPT AS OTHERWISE PROVIDED BELOW, THE DELIVERY WILL BE 
DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE EXCHANGE AGENT. INSTEAD OF 
DELIVERY BY MAIL, IT IS RECOMMENDED THAT HOLDERS USE AN OVERNIGHT OR HAND 
DELIVERY SERVICE.

     Holders whose Old Notes are not immediately available or who cannot 
deliver their Old Notes and all other required documents to the Exchange 
Agent on or prior to the Expiration Date may tender their Old Notes pursuant 
to the guaranteed delivery procedure set forth in the Prospectus under "The 
Exchange Offer -- Terms of the Exchange Offer -- Guaranteed Delivery 
Procedures." Pursuant to such procedure: (i) such tender must be made by or 
through an Eligible Institution (as defined in the Prospectus); (ii) on or 
prior to the Expiration Date, the Exchange Agent must have received from such 
Eligible Institution a letter, telegram or facsimile transmission setting 
forth the name and address of the tendering Holder, the name(s) in which such 
Old Notes are registered, and the certificate number(s) of the Old Notes to 
be tendered; and (iii) all tendered Old Notes as well as this Letter of 
Transmittal and all other documents required by this Letter of Transmittal 
must be received by the Exchange Agent within three New York Stock Exchange 
trading days after the date of execution of such letter, telex, telegram or 
facsimile transmission, all as provided in the Prospectus under the caption 
"The Exchange Offer -- Terms of the Exchange Offer -- Guaranteed Delivery 
Procedures."

     No alternative, conditional, irregular or contingent tenders will be 
accepted.  All tendering Holders, by execution of this Letter of Transmittal 
(or facsimile thereof), shall waive any right to receive notice of the 
acceptance of the Old Notes for exchange.

     2.   PARTIAL TENDERS; WITHDRAWALS.  If less than the entire number of 
Old Notes evidenced by a submitted certificate is tendered, the tendering 
Holder must fill in the number of shares tendered in the column entitled 
"Amount Tendered."  A newly issued certificate for the number of Old Notes 
submitted but not tendered will be sent to such Holder as soon as practicable 
after the Expiration Date.  All Old Notes delivered to the Exchange Agent 
will be deemed to have been tendered unless otherwise indicated.  To withdraw 
a tender of Old Notes in the Exchange Offer, a written or facsimile 
transmission notice of withdrawal must be received by the Exchange Agent at 
its address set forth herein prior to 5:00 p.m., New York City time, on the 
Expiration Date. Any such notice of withdrawal must (i) specify the name of 
the person having deposited the Old Notes to be withdrawn (the "Depositor"), 
(ii) identify the Old Notes to be withdrawn (including the certificate number 
or number of such Old Notes), (iii) contain a statement that such Holder is 
withdrawing its election to have such Old Notes exchanged, (iv) be signed by 
the Holder in the same manner as the original signature on the Letter of 
Transmittal by which such Old Notes were tendered (including any required 
signature guarantees) or be accompanied by documents of transfer 

                                      -8-
<PAGE>

sufficient to have the Trustee with respect to the Old Notes register the 
transfer of such Old Notes in the name of the person withdrawing the tender 
and (v) specify the name in which any such Old Notes are to be registered, if 
different from that of the Depositor. If Old Notes have been tendered 
pursuant to the procedure for book-entry transfer, any notice of withdrawal 
must specify the name and number of the account at the book-entry transfer 
facility. All questions as to the validity, form and eligibility (including 
time of receipt) of such notices will be determined by Continental, whose 
determination shall be final and binding on all parties. Any Old Notes so 
withdrawn will be deemed not to have been validly tendered for purposes of 
the Exchange Offer and no New Notes will be issued with respect thereto 
unless the Old Notes so withdrawn are validly retendered. Any Old Notes which 
have been tendered but which are not accepted for exchange will be returned 
to the Holder thereof without cost to such Holder as soon as practicable 
after withdrawal, rejection of tender or termination of the Exchange Offer. 
Properly withdrawn Old Notes may be retendered by following one of the 
procedures described herein at any time prior to the business day prior to 
the Expiration Date.

     3.   SIGNATURE ON THIS LETTER OF TRANSMITTAL; WRITTEN INSTRUMENTS AND 
ENDORSEMENTS; GUARANTEE OF SIGNATURES. If this Letter of Transmittal is 
signed by the registered Holder(s) of the Old Notes tendered hereby, the 
signature must correspond with the name(s) as written on the face of 
certificates without alteration, enlargement or any change whatsoever.

     If tendered Old Notes are registered in the name of the signer of the 
Letter of Transmittal and the New Notes to be issued in exchange therefor are 
to be issued (and any untendered Old Notes are to be reissued) in the name of 
the registered Holder (including any participant in The Depository Trust 
Company (also referred to as a book-entry facility) whose name appears on a 
security listing as the owner of Old Notes), the signature of such signer 
need not be guaranteed. In any other case, the tendered Old Notes must be 
endorsed or accompanied by written instruments of transfer in form 
satisfactory to Continental and duly executed by the registered Holder and 
the signature on the endorsement or instrument of transfer must be guaranteed 
by an eligible guarantor institution which is a member of one of the 
following recognized signature guarantee programs (an "Eligible 
Institution"): (i) The Securities Transfer Agents Medallion Program (STAMP), 
(ii) The New York Stock Exchange Medallion Signature Program (MSF), or (iii) 
The Stock Exchange Medallion Program (SEMP).

     If the New Notes or Old Notes not exchanged are to be delivered to an 
address other than that of the registered Holder appearing on the note 
register for the Old Notes, the signature in the Letter of Transmittal must 
be guaranteed by an Eligible Institution.

     Endorsements on certificates or signatures on separate written 
instruments of transfer or exchange required by this Instruction 3 must be 
guaranteed by an Eligible Institution.

     If any of the Old Notes tendered hereby are owned of record by two or 
more joint owners, all such owners must sign this Letter of Transmittal.

     If a number of Old Notes registered in different names are tendered, it 
will be necessary to complete, sign and submit as many separate copies of 
this Letter of Transmittal as there are different registrations of Old Notes.

                                      -9-
<PAGE>

     When this Letter of Transmittal is signed by the registered Holder or 
Holders of Old Notes listed and tendered hereby, no endorsements of 
certificates or separate written instruments of transfer or exchange are 
required.

     If this Letter of Transmittal is signed by a person other than the 
registered Holder or Holders of the Old Notes listed, such Old Notes must be 
endorsed or accompanied by separate written instruments of transfer or 
exchange in form satisfactory to Continental and duly executed by the 
registered Holder or Holders, in either case signed exactly as the name or 
names of the registered Holder or Holders appear(s) on the Old Notes.

     If this Letter of Transmittal, any certificates or separate written 
instruments of transfer or exchange are signed by trustees, executors, 
administrators, guardians, attorneys-in-fact, officers of corporations or 
others acting in a fiduciary or representative capacity, such persons should 
so indicate when signing, and, unless waived by Continental, proper evidence 
satisfactory to Continental of their authority so to act must be submitted.

     4.   TRANSFER TAXES.  Continental shall pay all transfer taxes, if any, 
applicable to the exchange of Old Notes pursuant to the Exchange Offer.  If, 
however, certificates representing New Notes, or Old Notes for principal 
amounts not tendered or accepted for exchange, are to be delivered to, or are 
to be issued in the name of, any person other than the registered Holder of 
the Old Notes tendered hereby, or if a transfer tax is imposed for any reason 
other than the exchange of Old Notes pursuant to the Exchange Offer, then the 
amount of any such transfer taxes (whether imposed on the registered Holder 
or any other person) will be payable by the tendering Holder.  If 
satisfactory evidence of payment of such taxes or exemption therefrom is not 
submitted herewith, the amount of such transfer taxes will be billed directly 
to such tendering Holder.

     Except as provided in this Instruction 4, it will not be necessary for 
transfer tax stamps to be affixed to the Old Notes listed in this Letter of 
Transmittal.

     5.   WAIVER OF CONDITIONS.  Continental reserves the absolute right to 
waive, in whole or in part, any of the conditions to the Exchange Offer set 
forth in the Prospectus.

     6.   MUTILATED, LOST, STOLEN OR DESTROYED NOTES.  Any Holder whose Old 
Notes have been mutilated, lost, stolen or destroyed should contact the 
Exchange Agent at the address indicated above for further instructions.

     7.   REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.  Questions relating 
to the procedure for tendering and other questions relating to the Exchange 
Offer, as well as requests for assistance or additional copies of the 
Prospectus and this Letter of Transmittal, may be directed to the Exchange 
Agent at the address and telephone number set forth above and in the 
Prospectus.

     8.   IRREGULARITIES.  All questions as to the validity, form, 
eligibility (including time of receipt), and acceptance of Letters of 
Transmittal or Old Notes will be resolved by Continental, whose determination 
will be final and binding.  Continental reserves the absolute right to reject 
any or all Letters of Transmittal or tenders that are not in proper form or 
the acceptance of which would, in the opinion of Continental's counsel, be 
unlawful.  Continental also reserves the right to waive any irregularities or 
conditions of tender as to the particular Old Notes covered by any Letter of 
Transmittal or tendered pursuant to such Letter of Transmittal.  

                                      -10-
<PAGE>

None of Continental, the Exchange Agent or any other person will be under any 
duty to give notification of any defects or irregularities in tenders or 
incur any liability for failure to give any such notification.  Continental's 
interpretation of the terms and conditions of the Exchange Offer shall be 
final and binding.

     9.   DEFINITIONS.  Capitalized terms used in this Letter of Transmittal 
and not otherwise defined have the meanings given in the Prospectus.

     10.  TAX IDENTIFICATION NUMBER.  Federal income tax law requires that a 
Holder of any Old Notes which are accepted for exchange must provide 
Continental (as payor) with its correct taxpayer identification number 
("TIN"), which, in the case of a Holder who is an individual, is his or her 
social security number. If Continental is not provided with the correct TIN, 
the Holder may be subject to a $50 penalty imposed by the Internal Revenue 
Service. (If withholding results in an over-payment of taxes, a refund may be 
obtained.) Certain Holders (including, among others, all corporations and 
certain foreign individuals) are not subject to these backup withholding and 
reporting requirements; however, these Holders still must submit the 
Substitute Form W-9.  See the enclosed "Guidelines for Certification of 
Taxpayer Identification Number on Substitute Form W-9" for additional 
instructions. 

     To prevent backup withholding, each tendering Holder must provide such 
Holder's correct TIN by completing the Substitute Form W-9 set forth herein, 
certifying that the TIN provided is correct (or that such Holder is awaiting 
a TIN), and that (i) the Holder has not been notified by the Internal Revenue 
Service that such Holder is subject to backup withholding as a result of 
failure to report all interest or dividends or (ii) the Internal Revenue 
Service has notified the Holder that such Holder is no longer subject to 
backup withholding. The Form must be signed, even if the Holder is exempt 
from backup withholding. If the Old Notes are registered in more than one 
name or are not in the name of the actual owner, consult the enclosed 
"Guidelines for Certification of Taxpayer Identification Number on Substitute 
Form W-9" for information on which TIN to report.

     Continental reserves the right in its sole discretion to take whatever 
steps are necessary to comply with its obligation regarding backup 
withholding. 

     IMPORTANT:  THIS LETTER OF TRANSMITTAL OR A FACSIMILE THEREOF (TOGETHER 
WITH CERTIFICATES FOR OLD NOTES AND ALL OTHER REQUIRED DOCUMENTS) OR A NOTICE 
OF GUARANTEED DELIVERY MUST BE RECEIVED BY THE EXCHANGE AGENT ON OR PRIOR TO 
THE EXPIRATION DATE.

                      10 1/4% SENIOR SUBORDINATED NOTES DUE 2008

                      10 1/4% SENIOR SUBORDINATED NOTES DUE 2008

To Our Clients:

     Enclosed for your consideration are the Prospectus, dated _______________,
1998 (the "Prospectus"), and the related Letter of Transmittal (which together
with the Prospectus constitute the "Exchange Offer") in connection with the
offer by Continental Resources, Inc., an Oklahoma corporation (the "Company"),
to exchange its 10 1/4% Senior Subordinated Notes due 2008 (the "New Notes") for
any and all of its outstanding 10 1/4% Senior Subordinated Notes due 2008 (the
"Old Notes"), upon the terms and subject to the conditions set forth in the
Exchange Offer.

     We are the Registered Holder of Old Notes held for your account.  An
exchange of the Old Notes can be made only by us as the Registered Holder and
pursuant to your instructions.  The Letter of Transmittal is furnished to you
for your information only and cannot be used by you to exchange the Old Notes
held by us for your account.  The Exchange Offer provides a procedure for
holders to tender by means of guaranteed delivery.

     We request information as to whether you wish us to exchange any or all of
the Old Notes held by us for your account upon the terms and subject to the
conditions of the Exchange Offer.

     Your attention is directed to the following:

          1.   The New Notes will be exchanged for the Old Notes at the rate of
     one-for-one.  The New Notes will accrue interest (as do the Old Notes) at a
     rate equal to 10 1/4% per annum from their date of issuance.  Holders of 
     Old Notes that are accepted for exchange will not receive accrued but 
     unpaid interest thereon on the date of issuance of the New Notes.  Such 
     interest will be paid with the first interest payment on the New Notes.  
     Interest on the Old Notes accepted for exchange will cease to accrue on 
     the day prior to the issuance of the New Notes.  The form and terms of the
     New Notes are the same in all material respects as the form and terms of 
     the Old Notes (which they replace) except that the New Notes have been 
     registered under the Securities Act of 1933, as amended (the "Securities 
     Act").

          2.   Based on the interpretation by the staff of the Securities and
     Exchange Commission (the "SEC"), New Notes issued pursuant to the Exchange
     Offer in exchange for Old Notes may be offered for resale, resold and
     otherwise transferred by holders thereof (other than any such holder which
     is an "affiliate" of the Company within the meaning of Rule 405 under the
     Securities Act or a "broker" or "dealer" registered under the Securities
     Exchange Act of 1934, as amended (the "Exchange Act")) without compliance
     with the registration and prospectus delivery provisions of the Securities
     Act provided that such New Notes are acquired in the ordinary course of
     such holders' business and such holders have no arrangement with any person
     to participate in the distribution of such New Notes.

          3.   The Exchange Offer is not conditioned on any minimum number of
     Old Notes being tendered.

<PAGE>

          4.   Notwithstanding any other term of the Exchange Offer, the Company
     will not be required to accept for exchange, or exchange New Notes for, any
     Old Notes not theretofore accepted for exchange, and may terminate or amend
     the Exchange Offer as provided herein before the acceptance of such Old
     Notes, if any of the conditions described in the Prospectus under "The
     Exchange Offer - Conditions of the Exchange Offer" exist.

          5.   Tendered Old Notes may be withdrawn at any time prior to 5:00
     p.m., New York City time, on _______________, 1998, if such Old Notes have
     not previously been accepted for exchange pursuant to the Exchange Offer.

          6.   Any transfer taxes applicable to the exchange of the Old Notes
     pursuant to the Exchange Offer will be paid by the Company, except as
     otherwise provided in Instruction 4 of the Letter of Transmittal.

     If you wish to have us tender any or all of your Old Notes, please so
instruct us by completing, detaching and returning to us the instruction form
attached hereto.  An envelope to return your instructions is enclosed.  If you
authorize a tender of your Old Notes, the entire principal amount of Old Notes
held for your account will be tendered unless otherwise specified on the
instruction form.  Your instructions should be forwarded to us in ample time to
permit us to submit a tender on your behalf by the Expiration Date.

     The Exchange Offer is not being made to, nor will tenders be accepted from
or on behalf of, holders of the Old Notes in any jurisdiction in which the
making of the Exchange Offer or acceptance thereof would not be in compliance
with the laws of such jurisdiction or would otherwise not be in compliance with
any provision of any applicable securities law.

                INSTRUCTION TO REGISTERED HOLDER FROM BENEFICIAL OWNER

     The undersigned acknowledge(s) receipt of your letter and the enclosed
Prospectus and the related Letter of Transmittal, in connection with the
Exchange Offer by the Company to exchange New Notes for Old Notes.

     This will instruct you to tender the principal amount of Old Notes
indicated below held by you for the account of the undersigned, upon the terms
and subject to the conditions set forth in the Prospectus and the related Letter
of Transmittal.

     The undersigned represents that (i) the New Notes acquired pursuant to the
Exchange Offer are being obtained in the ordinary course of its business, (ii)
it is not participating, does not intend to participate, and has no arrangement
or understanding with any person to participate, in the distribution of such New
Notes, and (iii) it is not an "affiliate," as defined under Rule 405 of the
Securities Act, of the Company or, if it is an affiliate, that it will comply
with the registration and prospectus delivery requirements of the Securities Act
to the extent applicable.

     If the undersigned is a "broker" or "dealer" registered under the Exchange
Act that acquired Old Notes for its own account pursuant to its market-making or
other trading activities (other than Old Notes acquired directly from the
Company), the undersigned understands and acknowledges that it may be deemed to
be an "underwriter" within the meaning of the Securities Act and, therefore,
must deliver a prospectus relating to the New Notes meeting the requirements of
the Securities Act in connection with any resales by it of New Notes acquired
for its own account in the Exchange Offer.  Notwithstanding the foregoing, the
undersigned does not thereby admit that it is an "underwriter" within the
meaning of the Securities Act.

     You are hereby instructed to tender all Old Notes held for the account of
the undersigned unless otherwise indicated below:

/ /  Do not tender any Old Notes

/ /  Tender Old Notes in the principal amount of $_______________

      GUIDELINES FOR CERTIFICATION OF TAXPAYER IDENTIFICATION
                   NUMBER ON SUBSTITUTE FORM W-9

GUIDELINES FOR DETERMINING THE PROPER IDENTIFICATION NUMBER TO GIVE THE 
PAYER.--Social Security numbers have nine digits separated by two hyphens: 
i.e., 000-00-0000. Employer identification numbers have nine digits separated 
by only one hyphen: i.e., 00-0000000. The table below will help determine the 
number to give the payer.

Exempt payees described above must still complete the Substitute Form W-9

FORM WITH THE PAYER. FURNISH YOUR TAXPAYER IDENTIFICATION NUMBER. WRITE 
EXEMPT ON THE FACE OF THE FORM, AND RETURN IT TO THE PAYER. IF THE PAYMENTS 
ARE INTEREST, DIVIDENDS, OR PATRONAGE DIVIDENDS, ALSO SIGN AND DATE THE FORM.

Certain payments, other than interest, dividends and patronage dividends, 
that are not subject to information reporting are also not subject to backup 
withholding. For details, see the regulations under sections 6041, 6041A(a), 
6042, 6044, 6045, 6049, 6050A and 6050N.

PRIVACY ACT NOTICE--Section 6109 requires most recipients of dividend, 
interest, or other payments to give taxpayer identification numbers to 
payers who must report the payments to IRS. IRS uses the numbers for 
identification purposes and to help verify the accuracy of the recipient's 
tax return. Payers must be given the numbers whether or not recipients are 
required to file tax returns. Payers must generally withhold 31% of taxable 
interest, dividend, and certain other payments to a payee who does not 
furnish a taxpayer identification number to a payer. Certain penalties may 
also apply.

PENALTIES

(1)  PENALTY FOR FAILURE TO FURNISH TAXPAYER IDENTIFICATION NUMBER.--If you 
fail to furnish your taxpayer identification number to a payer, you are 
subject to a penalty of $50 for each such failure which is due to reasonable 
cause and not to willful neglect.

(2)  CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING.--If you 
make a false statement with no reasonable basis which results in no 
imposition of backup withholding, you are subject to a penalty of $500.

(3)  CRIMINAL PENALTY FOR FALSIFYING INFORMATION.--Falsifying certifications 
or affirmations may subject you to criminal penalties including fines and/or 
imprisonment.

FOR ADDITIONAL INFORMATION CONTACT YOUR TAX CONSULTANT OR THE INTERNAL 
REVENUE SERVICE.
