                   SUBJECT TO COMPLETION, DATED July 3, 2002

PRELIMINARY PROSPECTUS

                         Magnum Hunter Resources, Inc.

                   Offer to Exchange all of Our Outstanding
                        9.60% Senior Notes due 2012 for
            9.60% Senior Notes due 2012, Which Have Been Registered
                       Under the Securities Act of 1933


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


   We are offering to exchange all of our outstanding unregistered 9.60% senior
notes due 2012 for registered 9.60% senior notes due 2012. We refer to the
registered senior notes as the new notes and the unregistered senior notes as
the old notes. We issued the old notes on March 15, 2002. As of the date of
this prospectus, an aggregate principal amount of $300 million of old notes is
outstanding. Please consider the following:

  .   Our offer to exchange the old notes for the new notes expires at 5:00
      p.m., New York City time, on       , 2002, unless we extend the offer.

  .   You should carefully review the procedures for tendering the old notes
      beginning on page 26 of this prospectus. If you do not follow these
      procedures, we may not exchange your old notes for new notes.

  .   We will not receive any proceeds from the exchange offer.

  .   If you do not tender your old notes, you will continue to hold
      unregistered securities and your ability to transfer them could be
      adversely affected.

  .   You may withdraw tendered old notes at any time before the expiration of
      the exchange offer.

   The terms of the new notes will be substantially identical to the old notes,
except for the elimination of some transfer restrictions, registration rights
and liquidated damages provisions relating to the old notes. We will pay
interest on the new notes on March 15 and September 15 of each year, beginning
September 15, 2002, at a rate of 9.60% per year. We may redeem some or all of
the new notes at any time, at a price described in this prospectus. Some of our
wholly owned subsidiaries have guaranteed the new notes on a senior unsecured
basis.

   There is currently no public market for the new notes. We do not intend to
list the new notes on any securities exchange. Therefore, we do not anticipate
that an active public market for the new notes will develop.

   You should read the section entitled "Risk Factors" beginning on page 9 for
a discussion of specific factors that you should consider before participating
in this exchange offer.

   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 representation to the contrary is
a criminal offense. Each broker-dealer that receives new notes for its own
account in exchange for old notes must acknowledge that it will deliver a
prospectus 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. We have agreed that, for a period of
180 days after the consummation of the exchange offer, we will make this
prospectus available to any broker-dealer for use in connection with any such
resale. See "Plan of Distribution."

              The date of this prospectus is                , 2002.

   The following summary contains information about Magnum Hunter and the
offering of the new notes. It does not contain all of the information that may
be important to you in making a decision to exchange your old notes. For a more
complete understanding of Magnum Hunter and this exchange offer, we urge you to

this prospectus, including the "Risk Factors"section. In this prospectus, when
we use the terms "Magnum Hunter,""we"or "our,"we mean Magnum Hunter Resources,
Inc. and all its subsidiaries on a consolidated basis, unless the context
requires otherwise.

                            Magnum Hunter Resources

   We are an independent energy company engaged in the exploration,
exploitation and development, acquisition and operation of oil and gas
properties with a geographic focus in the Mid-Continent Region, the Permian
Basin and the Gulf of Mexico/Gulf Coast. Our management has implemented a
business strategy that emphasizes acquisitions of long-lived proved reserves
with significant exploitation and development opportunities where we generally
could control the operations of the properties. As part of this strategy, from
1996 through 2001, we acquired significant properties from Burlington Resources
Inc., Spirit Energy 76, a business unit of Union Oil Company of California,
Vastar Resources, Inc. and Mallon Resources Corporation. In addition to our
focus on selected exploratory drilling prospects in the Gulf of Mexico as
described below, we intend to continue to concentrate our efforts on additional
producing property acquisitions strategically located within our geographic
area of operations. We also intend to continue to develop our substantial
inventory of drilling and workover opportunities located onshore. We have
identified over 358 development drilling locations (including both production
and injection wells) and workover opportunities on our properties to which
proved reserves have been attributed, substantially all of which are low-risk
in-fill drilling opportunities.

   In 1998, we acquired an approximate 40% beneficial ownership interest in TEL
Offshore Trust, a trust created under the laws of the state of Texas. The
principal asset of TEL Offshore Trust consists of a 99.99% interest in the TEL
Offshore Trust partnership. Chevron USA Inc. owns the remaining .01% interest
in the partnership. The partnership owns an overriding royalty interest
equivalent to a 25% net profits interest in certain oil and gas properties
located offshore Louisiana in the shallow waters in the Gulf of Mexico. As of
March 31, 2002, we owned approximately 36% of the units of beneficial ownership
in TEL Offshore Trust.

   Additionally, we own over 480 miles of gas gathering systems and a 50% or
greater ownership interest in three natural gas processing plants that are
located adjacent to certain producing properties owned and operated by us
located in the states of Texas, Oklahoma and Arkansas.

   At December 31, 2001, we had an interest in 3,241 wells and had estimated
proved reserves of 378 Bcfe with a PV-10 of $311.9 million. Approximately 70%
of these reserves were proved developed reserves: 31% were attributable to the
Mid-Continent Region, 33% were attributable to the Permian Basin, and 36% were
attributable to the Gulf of Mexico/Gulf Coast region. At December 31, 2001, our
proved reserves had an estimated reserve life of approximately 11.3 years and
were 66% natural gas. We serve as operator for approximately 70% of our
properties, based on the gross number of producing wells in which we own an
interest and 75% of our properties, based upon the year-end PV-10 value.

   As a result of our property acquisitions and successful drilling activities
during 2001, we have achieved growth as described below:

  .   Proved reserves increased 3% to 378 Bcfe at year-end 2001 from 367 Bcfe
      at year-end 2000; and

  .   Average daily production increased 22% to 91,292 MMcfe during fiscal 2001
      from 74,777 MMcfe in fiscal 2000. We had an exit rate of approximately
      100 MMcfe at year-end 2001.

                                      1



                               Recent Activities

   Merger with Prize Energy Corp.  On March 15, 2002 we acquired Prize Energy
Corp., which was merged into one of our wholly-owned subsidiaries. Prize was a
publicly traded independent oil and gas company engaged primarily in the
acquisition, enhancement and exploitation of producing oil and gas properties.
Prize owned oil and gas properties principally located in three core operating
areas, which were in the Permian Basin of West Texas and Southeastern New
Mexico, the onshore Gulf Coast area of Texas and Louisiana and the
Mid-Continent area of Oklahoma and the Texas Panhandle. Over 80% of Prize's oil
and gas property base was located in Texas.

   The merger resulted in an exchange of 2.5 shares of Magnum Hunter common
stock and $5.20 in cash for each share of Prize common stock, with the
stockholders of Prize becoming stockholders of Magnum Hunter. As a result of
the merger, we became owned approximately 52% by our then current stockholders
and 48% by the former stockholders of Prize, without taking into account
subsequent stock sales and the options and warrants that remained outstanding
at the time of the merger.

   In connection with our merger with Prize, we issued $300 million of 9.6%
unsecured senior notes due 2012 and established a new senior bank credit
facility with a borrowing base of $300 million secured by the assets of the
combined company. Proceeds from the senior notes offering and initial
borrowings under the new senior bank credit facility were used to refinance the
outstanding indebtedness under the existing senior bank credit facilities of
both Magnum Hunter and Prize, fund the cash component of the merger
consideration in the merger with Prize and pay costs and fees associated with
the merger.

   On March 15, 2002, we amended and restated our Senior Bank Credit Facility
in conjunction with the merger with Prize. The amended facility provides for
total borrowings of $500 million, up from $225 million, and raises the
borrowing base limit from $160 million to $300 million. The amended facility
requires us to comply with certain financial tests and maintain certain
financial ratios. We were not in compliance with the Funded Debt to EBITDA
Ratio (as defined by the facility) at March 31, 2002. We have obtained a waiver
from our lenders as of March 31, 2002 and have negotiated an amendment dated as
of July 3, 2002 which adjusted the Funded Debt to EBITDA Ratio (as defined by
the facility) to be less restrictive for the next four quarters ending
March 31, 2003. We believe we will be able to comply with the revised financial
covenants.

   Magnum Hunter Warrants Offering.  We have distributed to our stockholders of
record on January 10, 2002, warrants to purchase 7,228,457 shares of our common
stock at an exercise price of $15.00 per share and expiring three years from
the date of distribution. The warrant distribution occurred on or about March
21, 2002 and the warrants are traded on the American Stock Exchange. The
stockholders and warrantholders of Prize did not receive any of these warrants
in the merger or otherwise.

   Recent Commodity Hedging Transactions.  Periodically, we enter into
commodity price hedging transactions to reduce the effects of fluctuations in
crude oil and natural gas prices. At March 31, 2002, we had 72% of our natural
gas production and 69% of our crude oil production hedged through December 31,
2002. None of these hedges were with Enron, which recently filed for bankruptcy.

                               Business Strategy

   Our overall strategy is to increase our reserves, production, cash flow and
earnings utilizing a properly balanced program of:

  .   selective exploration;

                                      2



  .   the exploitation and development of acquired properties; and

  .   strategic acquisitions of additional proved reserves.

   The following are key elements of our strategy:

   Exploration.  We plan to continue to participate in drilling Gulf of Mexico
exploratory wells in an effort to add shorter-lived, higher output production
to our reserve mix. The continued use of 3-D seismic information as a tool in
our exploratory drilling in the Gulf of Mexico will be significant. We have
recently built a significant inventory of undrilled offshore lease blocks. We
plan to continue to align ourselves with other active Gulf of Mexico industry
partners who have similar philosophies and goals with respect to a "fast
track"program of placing new production online. This typically involves
drilling wells near existing infrastructure such as production platforms,
facilities and pipelines. We also maintain an active onshore exploration
program primarily concentrated in West Texas and Southeastern New Mexico where
we have various other operations in core areas. From time to time, we
participate in higher risk new exploration projects generated by third parties
in areas along the Gulf Coast of Texas and Louisiana.

   Exploitation and Development of Existing Properties.  As a result of the
merger with Prize, we now have a substantial inventory of over 1,000
development/exploitation projects which include development drilling, workovers
and recompletion opportunities. We will continue to seek to maximize the value
of our existing properties through development activities including in-fill
drilling, waterflooding and other enhanced recovery techniques. Typically, our
exploitation projects do not have significant time limitations due to the
existing mineral acreage being held by current production. By operating
substantially all of our properties, our management is provided maximum
flexibility with respect to the timing of capital expended to develop these
opportunities.

   Property Acquisitions.  Although we currently have an extensive inventory of
exploitation and development opportunities, we will continue to pursue
strategic acquisitions which fit our objectives of increasing proved reserves
in similar geographic regions that contain development or exploration potential
combined with maintaining operating control. We plan to continue to pursue an
acquisition strategy of acquiring long-lived assets where operating synergies
may be obtained and production enhancements, either on the surface or below
ground, may be achieved.

   Management of Overhead and Operating Costs.  We will continue to emphasize
strict cost controls in all aspects of our business and will continue to seek
to operate our properties wherever possible utilizing a minimum number of
personnel. By operating approximately 75% of our properties on a PV-10 basis we
will generally be able to control direct operating and drilling costs as well
as to manage the timing of development and exploration activities. This
operating control also provides greater flexibility as to the timing
requirements to fund new capital expenditures. By strictly controlling our
general and administrative expenses, management strives to maximize our net
operating margin.

   Expansion of Gas Gathering and Processing Operations.  We have implemented
several programs to expand and increase the efficiency of our gas gathering
systems and gas processing plants. We will consider opportunities to acquire or
develop additional gas gathering and processing facilities that are primarily
associated with our current production.

                              outstanding unregistered 9.60% Senior Notes due
                              2012. As of the date of this prospectus, $300

                              We have registered the new notes under the
                              Securities Act and they are substantially
                              identical to the old notes, except for the
                              elimination of some transfer restrictions,
                              registration rights and liquidated damages

                              sale, resold and otherwise transferred by you,
                              without compliance with the registration and

                                  with any person to participate in a

                              liability under the Securities Act. In addition,
                              if you are a broker-dealer seeking to receive new
                              notes for your own account in exchange for old
                              notes that you acquired as a result of
                              market-making or other trading activities, you
                              must acknowledge that you will deliver this
                              prospectus in connection with any offer to
                              resell, or any resale or other transfer of the
                              new notes that you receive in the exchange offer.

                                      4



Accrued interest on the new
  notes and the old notes...  Interest on the new notes will accrue from the
                              last interest payment date on which interest was
                              paid on the old notes or, if no interest was paid
                              on the old notes, from the date of issuance of
                              the old notes, which was March 15, 2002. Holders
                              whose old notes are accepted for exchange will be
                              deemed to have waived the right to receive any
                              interest on the old notes.

Conditions of the exchange
  offer.....................  The exchange offer is subject to customary
                              conditions that may be waived by us; however, the
                              exchange offer is not conditioned upon any
                              minimum aggregate principal amount of old notes
                              being tendered for exchange. We currently
                              anticipate that each of the conditions will be
                              satisfied and that we will not need to waive any
                              conditions. We reserve the right to terminate or
                              amend the exchange offer at any time before the
                              expiration date. For additional information, see

Special procedures for
  beneficial owners.........  If your old notes are registered in the name of a
                              broker, dealer, commercial bank, trust company or
                              other nominee and you wish to tender your old
                              notes, you should contact the registered holder
                              promptly and instruct the registered holder to
                              tender your old notes on your behalf. If you wish
                              to tender on your own behalf, you must, prior to
                              completing and executing the letter of

                              registered holder. The transfer of registered
                              ownership may take considerable time and may not
                              be able to be completed prior to the expiration
                              date.

Guaranteed delivery

                              cause the old notes, the letter of transmittal or
                              any other required documents to be transmitted

                              U.S. federal income tax purposes. See "Material
                              United States Income Tax Considerations."

                              entitled to any registration rights with respect
                              to your old notes unless:

                                  Securities Act of 1933 registration

                              unconditionally guaranteed by substantially all
                              of our current subsidiaries.

Optional redemption.........  Except as described below, we cannot redeem the
                              new notes until March 15, 2007. Thereafter we may
                              redeem some or all of the new notes at the
                              redemption prices listed in the "Description of
                              the New Notes"section under the heading "Optional
                              Redemption,"plus unpaid accrued interest to the
                              date of redemption

Optional redemption after
  equity offerings..........  At any time (which may be more than once) on or
                              before March 15, 2005, we may redeem up to 35% of
                              the outstanding new notes with money that we
                              raise in one or more equity offerings, as long as:

                              .   we pay 109.600% of the face amount of the new
                                  notes, plus interest;

                              .   we redeem the new notes within 60 days of
                                  completing the equity offering; and

                              .   at least 65% of the aggregate principal
                                  amount of new notes issued remains
                                  outstanding afterwards.

                                      7



Change of control offer.....  If we experience a change of control, we must
                              give holders of the new notes the opportunity to
                              sell us their notes at 101% of their principal
                              amount, plus unpaid accrued interest.

Asset sale proceeds.........  If we or our subsidiaries engage in asset sales,
                              we generally must either invest the net cash
                              proceeds from such sales in our business within a
                              period of time, prepay the debt under our new
                              credit facility, repurchase our existing senior
                              notes or make an offer to purchase a principal
                              amount of the new notes equal to the excess net
                              cash proceeds. The purchase price of the new
                              notes will be 100% of their principal amount,
                              plus unpaid accrued interest.

Certain indenture provisions  The indenture governing the new notes contains
                              covenants limiting our (and our restricted
                              subsidiaries') ability to:

                              .   incur additional indebtedness;

                              .   make restricted payments (including paying
                                  dividends on, redeeming or repurchasing our
                                  capital stock);

                              .   make investments or acquisitions;

                              .   sell our assets;

                              .   grant liens on our assets;

                              .   engage in transactions with affiliates; and

                              .   merge or consolidate or transfer
                                  substantially all of our assets.

                              These covenants are subject to a number of
                              important limitations and exceptions.

Use of proceeds.............  We will not receive any cash proceeds from the
                              exchange offer. For a description of the use of
                              proceeds from the offering of the old notes, see
                              "Use of Proceeds."

Absence of a public market
  for the new notes.........  The new notes are new securities. There has been
                              no public market for the old notes, and we do not
                              anticipate that an active market for the new
                              notes will develop. The new notes will not be
                              listed on any securities exchange or included in
                              any automated quotation system. As a result, we
                              cannot assure you that any active or liquid
                              market will develop for the new notes.

Risk Factors................  See "Risk Factors" for a description of certain
                              of the risks associated with the new notes.

                                      8



                                 RISK FACTORS

   You should carefully consider the risks and uncertainties described below
and the other information contained or incorporated by reference in this
prospectus before deciding to participate in the exchange offer.

Risks Related to the Exchange Offer and Our Indebtedness

  You may be adversely affected if you do not exchange your old notes.

   If you do not exchange your old notes for new notes pursuant to the exchange
offer, you will continue to be subject to the transfer restrictions on your old
notes. Except in limited circumstances, you will have no further registrations
rights. The transfer restrictions on your old notes arise because we issued the
old notes pursuant to exemptions from, or in transactions not subject to, the
registration requirements of the Securities Act of 1933 and applicable state
securities laws. In general, you may only offer or sell the old notes if they
are registered under the Securities Act of 1933 and applicable state securities
laws, or offered and sold pursuant to an exemption from those requirements. We
do not intend to register the old notes under the Securities Act of 1933. In
addition, if you exchange your old notes in the exchange offer for the purpose
of participating in a distribution of the new notes, you may be deemed to have
received restricted securities. In those circumstances, you will be required to
comply with the registration and prospectus delivery requirements of the
Securities Act of 1933 in connection with any resale transaction. To the extent
old notes are tendered and accepted in the exchange offer, the trading market,
if any, for the old notes would be adversely affected. See "The Exchange
Offer--Consequences of Failure to Exchange Old Notes."

  You must tender the old notes in accordance with proper procedures in order
  to ensure the exchange will occur.

   We will only exchange old notes for new notes if you follow the proper
procedures, as detailed in this prospectus. We will issue the new notes in
exchange for the old notes if the exchange agent receives the old notes or a
book-entry confirmation, a properly completed and executed transmittal letter,
or an agent's message, and all other required documentation in a timely manner.
If you want to tender your old notes in exchange for new notes, you should
allow sufficient time to ensure timely delivery. Neither we nor the exchange
agent is under any duty to give you notification of defects or irregularities
with respect to tenders of old notes for exchange. In addition, if you are an
affiliate of ours or you tender the old notes in the exchange offer in order to
participate in a distribution of the new notes, you will be required to comply
with the registration and prospectus delivery requirements of the Securities
Act of 1933 in connection with any resale transaction. For additional
information, please refer to the sections entitled "The Exchange Offer" and
"Plan of Distribution."

  We have a significant amount of debt.

   In connection with our merger with Prize, we issued $300 million of 9.6%
senior notes due 2012 and established a new credit facility with a borrowing
base of $300 million secured by the assets of the combined company. Proceeds
from the senior notes offering and borrowings under the new credit facility
were used to refinance the outstanding indebtedness under the existing senior
credit facilities of both Magnum Hunter and Prize, fund the cash component of
the merger consideration in the merger with Prize and pay costs and fees
associated with the merger. As a result of the merger, the combination of our
outstanding 10.00% senior notes due 2007, our new issuance of the 9.6% senior
notes due 2012 and our new senior bank credit facility, created outstanding
long term debt of approximately $634.9 million as of March 31, 2002. Because we
must dedicate a substantial portion of our cash flow from operations to the
payment of interest on our debt, that portion of our cash flow is not available
for other purposes. The covenants contained in our new credit facility and the
indentures relating to our two issuances of senior notes require us to meet
financial tests and limit our ability to borrow additional funds or to acquire
or dispose of assets. Also, our ability to obtain additional financing in the
future may be impaired by our substantial leverage. Additionally, the senior,
as opposed to subordinated, status of our 10% senior notes due 2007 and our
9.6% senior notes due 2012, our high debt to equity ratio, and the pledge of
substantially all of our assets as collateral for our new credit facility will,
for the foreseeable future, make it difficult for us to obtain financing on an
unsecured basis or to obtain secured financing other than "purchase money"
indebtedness collateralized by the acquired assets.

                                      9



  Our new credit facility and the indentures governing our senior notes impose
  restrictions on us that may limit the discretion of our management in
  operating our business that, in turn, could impair our ability to repay our
  obligations under the new notes.

   Our new credit facility and the indentures governing our senior notes
contain various restrictive covenants that limit our management's discretion in
operating our business. In particular, these covenants limit our ability to,
among other things:

  .   incur additional debt;

  .   make restricted payments (including paying dividends on, redeeming or
      repurchasing our capital stock);

  .   make investments or acquisitions;

  .   grant liens on assets;

  .   sell our assets;

  .   engage in transactions with affiliates; and

  .   merge, consolidate or transfer substantially all of our assets.

   Under some circumstances, including if we fail to meet certain financial
tests, the indentures governing our senior notes prohibit us from borrowing the
full amount of availability under our new credit facility.

   Our new credit facility also requires us to maintain specified financial
ratios and satisfy some financial tests. Our ability to maintain or meet these
financial ratios and tests may be affected by events beyond our control,
including changes in general economic and business conditions, and we cannot
assure you that we will maintain or meet these ratios and tests or that the
lenders under the new credit facility will waive any failure to meet these
ratios or tests. A breach of any of these covenants could result in an event of
default under the new credit facility, in which case, the lenders could elect
to declare all amounts borrowed under the new credit facility, together with
unpaid accrued interest, to be immediately due and payable and to terminate all
commitments under the new credit facility.

  We may not be able to generate a sufficient amount of cash flow to meet our
  debt service obligations.

   Our ability to make scheduled payments or to refinance our obligations with
respect to our debt will depend on our financial and operating performance,
which, in turn, is subject to prevailing economic conditions and to certain
financial, business and other factors beyond our control. If our cash flow and
capital resources are insufficient to fund our debt service obligations, we may
be forced to reduce or delay scheduled expansions and capital expenditures,
sell material assets or operations, obtain additional capital or restructure
our debt. We cannot assure you that our operating performance, cash flow and
capital resources will be sufficient for payment of our debt in the future. In
the event that we are required to dispose of material assets or operations or
restructure our debt to meet our debt service and other obligations, we cannot
assure you as to the terms of any such transaction or how soon any such
transaction could be completed.

  The new notes are unsecured and effectively subordinated to our secured
  indebtedness.

   The new notes will not be secured. Our new credit facility is secured by
substantially all of our assets and the assets of our subsidiaries. If we
become insolvent or are liquidated, or if payment under any of this facility or
any of our other secured debt obligations is accelerated, our lenders would be
entitled to exercise the remedies available to a secured lender under
applicable law and will have a claim on those assets before the holders of the
new notes. As a result, the new notes are effectively subordinated to our
secured indebtedness to the extent of the value of the assets securing that
indebtedness and the holders of the new notes may recover ratably less than the
lenders of our secured debt in the event of our bankruptcy or liquidation.

                                      10



  In the event of our bankruptcy or liquidation, holders of the new notes will
  be paid from any assets remaining after payments to any holders of debt of
  certain of our subsidiaries.

   The new notes will be structurally subordinated to the liabilities of our
subsidiaries that are not guarantors. If we are declared bankrupt or insolvent,
or are liquidated, the holders of any debt of our non-guarantor subsidiaries
will be entitled to be paid from the assets of the non-guarantor subsidiaries
before any payment may be made with respect to the new notes. If any of the
foregoing events occur, we cannot assure you that we will have sufficient
assets to pay amounts due on the debt of our non-guarantor subsidiaries and the
new notes.

  We are dependent upon cash from our subsidiaries to meet our debt service
  obligations.

   We conduct a significant portion of our operations through our subsidiaries.
Our ability to meet our debt service obligations will be dependent on receipt
of cash from our direct and indirect subsidiaries. We have one or more
subsidiaries that are not guarantors, and such non-guarantor subsidiaries do
not have obligations with respect to the new notes. However, at present, such
non-guarantor subsidiaries do not generate a significant portion of our
operating income and cash flow. Future borrowings by our non-guarantor
subsidiaries may contain restrictions or prohibitions on the payment of
dividends by such subsidiaries to us.

  We may not be able to finance change of control offers.

   If we were to experience a change of control, as defined in the indenture
governing the new notes or the indenture governing our 10% Senior Notes, one or
both of those indentures would require us to purchase all of the new notes and
10% Senior Notes, respectively, then outstanding at 101% of their principal
amount, plus unpaid accrued interest to the date of repurchase. If a change of
control were to occur, we cannot assure you that we would have sufficient funds
to purchase the new notes and our 10% Senior Notes. In addition, our new credit
facility restricts our ability to repurchase the new notes and our 10% Senior
Notes, even when we are required to do so by the indentures in connection with
a change of control. A change of control could therefore result in a default
under the new credit facility and could cause the acceleration of the new
senior credit facility debt. The inability to repay such debt, if accelerated,
and to repurchase all of the tendered notes, would constitute an event of
default under the indentures.

  The guarantees may not be enforceable because of fraudulent conveyance laws.

   The incurrence of the guarantees by the guarantors may be subject to review
under U.S. federal bankruptcy law or relevant state fraudulent conveyance law
if a bankruptcy case or lawsuit is commenced by or on behalf of the guarantors'
unpaid creditors. Under these laws, if in such a case or lawsuit a court were
to find that, at the time such guarantor incurred a guarantee of the new notes,
such guarantor:

  .   incurred the guarantee of the new notes with the intent of hindering,
      delaying or defrauding current or future creditors; or

  .   received less than reasonably equivalent value or fair consideration for
      incurring the guarantee of the new notes and such guarantor:

      -- was insolvent or was rendered insolvent;

      -- was engaged, or about to engage, in a business or transaction for
        which its remaining assets constituted unreasonably small capital to
        carry on its business; or

      -- intended to incur, or believed that it would incur, debts beyond its
        ability to pay as such debts matured (as all of the foregoing terms are
        defined in or interpreted under the relevant fraudulent transfer or
        conveyance statutes);

then such court could avoid the guarantee of such guarantor or subordinate the
amounts owing under such guarantee to such guarantor's presently existing or
future debt or take other actions detrimental to you.

   It may be asserted that the guarantors incurred their guarantees for our
benefit and they incurred the obligations under the guarantees for less than
reasonably equivalent value or fair consideration.

                                      11



   The measure of insolvency for purposes of the foregoing considerations will
vary depending upon the law of the jurisdiction that is being applied in any
such proceeding. Generally, a company would be considered insolvent if, at the
time it incurred the debt or issued the guarantee, either:

  .   the sum of its debts (including contingent liabilities) is greater than
      its assets, at fair valuation; or

  .   the present fair saleable value of its assets is less than the amount
      required to pay the probable liability on its total existing debts and
      liabilities (including contingent liabilities) as they become absolute
      and matured.

   If a guarantee is avoided as a fraudulent conveyance, or found to be
unenforceable for any other reason, you will not have a claim against that
obligor and will only be a creditor of us or any guarantor whose obligation was
not set aside or found to be unenforceable.

  There is no public market for the new notes.

   We do not intend to list the new notes on any national securities exchange
or to seek the admission thereof to trading on the Nasdaq Market. The initial
purchasers have advised us that they currently intend to make a market in the
new notes. However, the initial purchasers are not obligated to make a market
in the new notes and any market making may be discontinued at any time without
notice. Therefore, there can be no assurance as to the development of any
market or the liquidity of any market that may develop for the notes.

   Historically, the market for non-investment grade debt has been subject to
disruptions that have caused substantial volatility in the prices of securities
similar to the notes. We cannot assure you that the market for the new notes,
if any, will not be subject to similar disruptions. Any such disruptions may
adversely affect you as a holder of the new notes.

Risks Associated with our Merger with Prize

  We may not achieve the expected benefits of the merger.

   The merger was intended to achieve specific goals. The likelihood of
achieving those goals represented the subjective judgment of our senior
management and board of directors. Some of those goals may not be achieved or,
if achieved, may not be achieved in the time frame in which they were expected.
Whether the combined company will actually realize these anticipated benefits
depends on future events and circumstances beyond the control of the combined
company, including the following:

  .   A decline in economic conditions in general or in the oil and gas
      industry in particular could cause our combined company to fail to meet
      the expectations of our board of directors for revenue, earnings and cash
      flow.

  .   Differing opinions of securities analysts and investors regarding the
      prospects for our combined company's business and our future financial
      condition could reduce the likelihood that our combined company will
      enjoy the hoped-for increase in stock market valuation multiples relative
      to the stock market valuation multiples of smaller competitors.

  .   The other risk factors discussed below may prevent the achievement of the
      believed advantages of the merger.

Because of these and other factors, it is possible that our combined company
will not realize some or all of the expected benefits of the merger.

  We may face difficulties in integrating the operations of Magnum Hunter and
  Prize.

   Before the merger, Magnum Hunter and Prize operated separately. Magnum
Hunter's management team has no experience in running the combined business. We
may not be able to integrate all of the operations of

                                      12



Magnum Hunter and Prize within the time frame anticipated and without an
unexpected loss of key employees, customers or suppliers, a loss of revenues,
an increase in operating or other costs or other difficulties. In addition, we
may not be able to realize all of the operating efficiencies, synergies, cost
savings or other benefits originally anticipated from the merger. Any
unexpected costs or delays incurred in connection with the integration could
have an adverse effect on our business, results of operations or financial
condition.

  As a result of the merger with Prize, our risk profile is different from that
  of Magnum Hunter and Prize before the merger.

   We were relatively more active in onshore exploration and in offshore
exploration and production than Prize, which did not engage in these
activities. As a result, the combined company will have a different risk
profile than either company had before the merger.

   The combined company's oil and gas business involves a variety of operating
risks, including unexpected formations or pressures, uncontrollable flows of
oil, gas, brine or well fluids into the environment (including groundwater
contamination), blowouts, fires, explosions, pollution, marine hazards and
other risks, any of which could cause personal injuries, loss of life, damage
to properties and substantial losses. Although we carry, and will continue to
carry, insurance at levels that we believe are reasonable, we will not be fully
insured against all risks. We will not carry business interruption insurance
except on rare occasions. Losses and liabilities arising from uninsured or
under-insured events could materially affect the combined company's financial
condition and operations.

  The price of our common stock may decline as a result of the merger with
  Prize.

   The number of issued shares of Magnum Hunter common stock increased
substantially as a result of the merger with Prize, from 35,972,484 shares on
March 1, 2002 to approximately 70,065,447 shares as of March 15, 2002. If
holders of a significant number of these new shares elect not to retain their
shares, the market price of our common stock may vary sharply or decline for
reasons unrelated to the financial performance of the combined company.

Risks Relating to Our Business

  A decrease in oil and natural gas prices will adversely affect our business.

   Our revenues, profitability and the carrying value of our oil and gas
properties depend substantially upon prevailing prices of, and demand for, oil
and gas and the costs of acquiring, finding, developing and producing reserves.
Oil and gas prices also substantially affect our ability to maintain or
increase our borrowing capacity, to repay current or future indebtedness, and
to obtain additional capital on attractive terms. Historically, the markets for
oil and gas have been volatile and are likely to continue to be volatile in the
future. In 1999 and 2000, oil and natural gas prices increased compared to
prices in the previous two years. However, beginning in mid-2001, oil and
natural gas prices began declining. Prices for oil and gas fluctuate widely in
response to:

  .   relatively minor changes in the supply of, and demand for, oil and gas;

  .   market uncertainty; and

  .   a variety of additional factors, all of which are beyond our control.

   These additional factors include domestic and foreign political conditions,
the price and availability of domestic and imported oil and gas, the level of
consumer and industrial demand, weather, domestic and foreign government
relations, the price and availability of alternative fuels and overall economic
conditions. Also, our ability to market our production depends in part upon the
availability, proximity and capacity of gathering systems, pipelines and
processing facilities. Volatility in oil and gas prices could affect our
ability to market our production through such systems, pipelines or facilities.
Currently, we sell substantially all our gas production to

                                      13



gas marketing firms or end users either on the spot market on a month-to-month
basis at prevailing spot market prices or under long-term contracts based on
current spot market prices.

   Under the full cost accounting method, we are required to take a non-cash
charge against earnings if capitalized costs of acquisition, exploration and
development, net of depletion, depreciation and amortization, less deferred
income taxes, exceed the present value of our proved reserves and the lower of
cost or fair value of unproved properties after income tax effects. Once
incurred, a write down of oil and gas properties is not reversible at a later
date even if oil and gas prices increase.

   At December 31, 2000, NYMEX prices were $26.80 per Bbl for oil and $9.78 per
Mcf for gas. At December 31, 2001, NYMEX prices were $19.78 per Bbl for oil, a
decline of 26% from year-end 2000, and $2.72 per Mcf for gas, a decline of 72%
from year-end 2000. Our capitalized costs again exceeded the PV-10 limitation
utilizing commodity prices in effect at December 31, 2001 under the full cost
method of accounting by $76.0 million. However, no writedown for impairment of
our oil and gas properties is required, due to higher oil and gas prices that
have been recorded in the market subsequent to December 31, 2001.

  You should not place undue reliance on our reserve data because they are
  estimates.

   This prospectus incorporates by reference estimates of our oil and gas
reserves and the future net cash flows that were prepared by independent
petroleum consultants as of December 31, 2001. There are numerous uncertainties
inherent in estimating quantities of proved reserves of oil and natural gas and
in projecting future rates of production and the timing of development
expenditures, including many factors beyond our control. The estimates
incorporated by reference into this prospectus rely on various assumptions,
including, for example, constant oil and gas prices, operating expenses,
capital expenditures and the availability of funds, and are therefore
inherently imprecise indications of future net cash flows. Actual future
production, cash flows, taxes, operating expenses, development expenditures and
quantities of recoverable oil and gas reserves may vary substantially from
those assumed in the estimates. Any significant variance in these assumptions
could materially affect he estimated quantity and value of reserves.

  Maintaining reserves and revenues in the future depends on successful
  exploration and development.

   Our future success depends upon our ability to find or acquire additional
oil and gas reserves that are economically recoverable. Unless we successfully
explore or develop or acquire properties containing proved reserves, our proved
reserves will generally decline as we produce them. The decline rate varies
depending upon reservoir characteristics and other factors. Our future oil and
gas reserves and production, and, therefore, cash flow and income, depend
greatly upon our success in exploiting our current reserves and acquiring or
finding additional reserves. We cannot assure you that our planned development
projects and acquisition activities will result in significant additional
reserves or that we will successfully drill productive wells at economic
returns to replace our current and future production.

  We may not be able to meet our capital requirements.

   We will need to continue to make substantial capital expenditures for the
acquisition, enhancement, exploitation and production of oil and natural gas
reserves. Without successful enhancement, exploitation and acquisition
activities, our reserves and revenues will decline over time. We intend to
finance our capital expenditures, other than significant acquisitions, from
internally generated funds provided by operations and borrowings under our new
credit facility. Our ability to borrow under the new credit facility in the
future may be limited by redetermination of the borrowing base or our failure
to meet certain financial tests under the indentures governing the new notes
and our existing 10% Senior Notes. If our cash flow from operations and
availability under the new credit facility are not sufficient to satisfy
capital expenditure requirements, there can be no assurance that additional
debt or equity financing will be available to allow us to fund our continued
growth.

                                      14



  Our exploration and development activities are subject to significant risks.

   Our oil and gas business involves a variety of operating risks, including
unexpected formations or pressures, uncontrollable flows of oil, gas, brine or
well fluids into the environment (including groundwater contamination),
blowouts, fires, explosions, pollution, marine hazards and other risks, any of
which could cause personal injuries, loss of life, damage to properties and
substantial losses.

   We cannot assure you that the new wells we drill will be productive or that
we will recover all or any portion of our investment in wells drilled. Drilling
for oil and natural gas may involve unprofitable efforts, not only from dry
wells, but from wells that are productive but do not produce net reserves to
return a profit after drilling, operating and other costs. The cost of
drilling, completing and operating wells is often uncertain. Numerous factors,
including title problems, weather conditions, compliance with governmental
requirements and shortages or delays in the delivery of equipment, may curtail,
delay or cancel drilling operations.

   We have also recently been more active in offshore exploration and
production. Offshore operations are also subject to a variety of operating
risks peculiar to the marine environment, such as capsizing, collisions or
damage or loss from hurricanes or other adverse weather conditions. These
conditions can cause substantial damage to facilities and interrupt production.
As a result, we could incur substantial liabilities.

   In accordance with customary industry practices, we maintain insurance
against some, but not all, of such risks and losses. Although we carry
insurance at levels that we believe are reasonable, we are not fully insured
against all risks. We do not carry business interruption insurance except on
rare occasions. Losses and liabilities arising from uninsured or under-insured
events could materially affect our financial condition and operations.

  We conduct waterflood projects and other secondary recovery operations.

   Secondary recovery operations involve certain risks, especially the use of
waterflooding techniques. Our inventory of development prospects include
waterflood projects. With respect to our properties located in the Permian
Basin, we have identified significant potential expenditures related to further
developing existing waterfloods. Waterflooding involves significant capital
expenditures and uncertainty as to the total amount of recoverable secondary
reserves. In waterflood operations, there is generally a delay between the
initiation of water injection into a formation containing hydrocarbons and any
increase in production. The operating cost per unit of production of waterflood
projects is generally higher during the initial phases of such projects due to
the purchase of injection water and related costs. Costs are also higher during
the later stages of the life of the project as production declines. The degree
of success, if any, of any secondary recovery program depends on a large number
of factors, including the amount of primary production, the porosity and
permeability of the formation, the technique used, the location of injector
wells and the spacing of both producing and injector wells.

  We hedge our oil and gas production.

   Periodically, we have entered into hedging transactions to reduce the
effects of fluctuations in crude oil and natural gas prices. At March 31, 2002,
we had 72% of our natural gas production and 69% of our crude oil production
hedged through December 31, 2002. The hedging activities of the combined
company, while intended to reduce sensitivity to changes in market prices of
oil and gas, are subject to a number of risks including instances in which we
or the counterparties to our hedging contracts fail to perform. Additionally,
the fixed price sales and hedging contracts limit the benefits the combined
company will realize if actual prices rise above the contract prices.

  Our operations are subject to many laws and regulations.

   The oil and gas industry is heavily regulated. Extensive federal, state,
local and foreign laws and regulations relating to the exploration for and
development, production, gathering and marketing of oil and gas affect our

                                      15



operations. Some of the regulations set forth standards for discharge permits
for drilling operations, drilling and abandonment bonds or other financial
responsibility requirements, reports concerning operations, the spacing of
wells, unitization and pooling of properties and taxation. From time to time,
regulatory agencies have imposed price controls and limitations on production
by restricting the rate of flow of oil and gas wells below actual production
capacity to conserve supplies of oil and gas.

   Numerous environmental laws, including but not limited to those governing
the management of waste, the protection of water and air quality, the discharge
of materials into the environment, and the preservation of natural resources,
impact and influence our operations. If we fail to comply with environmental
laws regarding the discharge of oil, gas, or other materials into the air, soil
or water we may be subject to liabilities to the government and third parties,
including civil and criminal penalties. These regulations may require us to
incur costs to remedy the discharge. Laws and regulations protecting the
environment have become more stringent in recent years, and may, in some
circumstances, result in liability for environmental damage regardless of
negligence or fault. New laws or regulations, or modifications of or new
interpretations of existing laws and regulations, may increase substantially
the cost of compliance or adversely affect our oil and gas operations and
financial condition. From time to time, we have agreed to indemnify sellers of
producing properties against some liabilities for environmental claims
associated with these properties. Material indemnity claims may also arise with
respect to properties acquired by or from us. While we do not anticipate
incurring material costs in connection with environmental compliance and
remediation, we cannot guarantee that we will not incur material costs.

  Marketability of our oil and natural gas production may be affected by
  factors beyond our control.

   The marketability of our production depends in part upon the availability,
proximity and capacity of natural gas gathering systems, pipelines and
processing facilities. Most of our natural gas is delivered through gathering
systems and pipelines that we do not own. Federal and state regulation of oil
and natural gas production and transportation, tax and energy policies, changes
in supply and demand and general economic conditions all could adversely affect
our ability to produce and market our oil and natural gas.

  Our acquisitions involve certain risks.

   We have grown significantly through acquisitions and intend to continue
acquiring oil and gas properties in the future. Although we review and analyze
the properties that we acquire, such reviews are subject to uncertainties. It
generally is not possible to review in detail every individual property
involved in an acquisition. Our assessments of matters such as recoverable
reserves and potential environmental liabilities is necessarily inexact. We do
not always conduct inspections on every well, and ordinarily focus our review
on the higher-valued properties. However, even a detailed review of all
properties and records may not reveal existing or potential problems, and
inspection of a specific well might not result in detection of potential
problems, such as mechanical integrity of equipment and environmental
conditions, that may require significant remedial expenditures.

   As the Prize merger demonstrates, we have begun to focus our acquisition
efforts on larger packages of oil and gas properties. Acquisitions of larger
oil and gas properties may involve substantially higher costs and may pose
additional issues regarding operations and management. We cannot assure you
that we will be able to successfully integrate all of the oil and gas
properties that we acquire into our operations or that we will achieve desired
profitability objectives.

  We are subject to substantial competition.

   We encounter substantial competition in acquiring properties, drilling for
new reserves, marketing oil and gas, securing trained personnel and operating
our properties. Many competitors have financial and other resources that
substantially exceed our resources. Our competitors in acquisitions,
development, exploration and

                                      16



production include major oil companies, natural gas utilities, numerous
independents, individual proprietors and others. Our competitors may be able to
pay more for desirable leases and may be able to evaluate, bid for and purchase
a greater number of properties or prospects than our financial or personnel
resources will permit.

  Our business may be adversely affected if we lose our key personnel.

   We depend greatly upon three key individuals within our management team:
Gary C. Evans, Richard R. Frazier and Charles R. Erwin. The loss of the
services of any of these individuals could materially impact our operations.

  Certain of our principal stockholders can significantly influence all matters
  requiring the approval of our stockholders, and their interests in our
  business may be different than yours.

   Natural Gas Partners V, L.P. owns approximately 26% of our outstanding
common stock. As a result of this voting power, this stockholder has the
ability to significantly influence the outcome of substantially all matters
which may be put to a vote of our stockholders, including the election of our
directors, amendments to our articles of incorporation and bylaws and approval
of significant corporate transactions, including mergers and sales of
substantially all of our assets. This may also delay or prevent a change in our
management or voting control. You should consider that the interests of Natural
Gas Partners V, L.P. as an equity investor will likely differ from your
interests in material respects.

                                USE OF PROCEEDS

   We intend the exchange offer to satisfy our obligations under the
registration rights agreement that we entered into in connection with the
offering of the old notes. We will not receive any cash proceeds from the
issuance of the new notes pursuant to the exchange offer. Old notes surrendered
in exchange for the new notes will be retired and cancelled and cannot be
reissued. As a result, the issuance of the new notes will not result in any
increase or decrease in our indebtedness. We have agreed to bear the expenses
of the exchange offer. No underwriter is being used in connection with the
exchange offer.

   The net proceeds from the issuance and sale of the old notes was
approximately $291.7 million. We used all of the net proceeds of the sale of
the old notes, together with the borrowings under the new credit facility, to
refinance the outstanding indebtedness under the existing senior bank credit
facilities of both Magnum Hunter and Prize, fund the cash component of the
merger consideration in the merger with Prize and pay costs and fees associated
with the merger.

(1) Includes the effect in the year 2000 of the payment of a $5.5 million fee
    upon redemption of $25.0 million (liquidation value) of Magnum Hunter's
    1999 Series A 8% convertible preferred stock. The fee was treated as a
    dividend, reducing income available to common stockholders for the year
    2000.
(2) Capital expenditures include cash expended for acquisitions plus normal
    additions to oil and natural gas properties and other fixed assets.
    Additionally, the year 2000 amount includes the cost of property acquired
    through the issuance of common stock with a fair value of $3.5 million on
    the acquisition date.
(3) EBITDA is defined as income (loss) from continuing operations before income
    taxes, minority interest and equity in earnings of affiliate, plus the sum
    of depreciation, depletion and amortization and interest expense. EBITDA is
    presented because it is commonly accepted in the oil and gas industry as a
    financial indicator of a company's ability to service or incur debt and
    because it is a component of Magnum Hunter's debt covenants. EBITDA is also
    presented because investors routinely request such information. Management
    of Magnum Hunter interprets trends in EBITDA in a similar manner as trends
    in net income. EBITDA should be used as a supplement, to, and not as
    substitute for, net income and cash provided by operating activities,
    determined in accordance with generally accepted accounting principles, as
    measures of Magnum Hunter's profitability and liquidity. There may be
    operational or financial demands and requirements that reduce management's
    discretion over the use of EBITDA. EBITDA as used by Magnum Hunter may not
    be comparable to similarly titled measured by other companies.

                              THE EXCHANGE OFFER

   This section of the prospectus describes the proposed exchange offer. While
we believe that the description covers the material terms of the exchange
offer, this summary may not contain all of the information that is important to
you. You should carefully read this entire document and the other documents
referred to herein for a more complete understanding of the exchange offer.

Purpose of the Exchange Offer

   In connection with the issuance of the old notes, we entered into a
registration rights agreement which provides for the exchange offer. A copy of
the registration rights agreement is filed as an exhibit to the registration
statement of which this prospectus is a part. Under the registration rights
agreement we agreed that we would, subject to certain exceptions:

  .   within 90 days after the issue date of the old notes, file a registration
      statement with the SEC with respect to a registered offer to exchange the
      old notes for new notes having terms substantially identical in all
      material respects to the old notes (except that the new notes will not
      contain terms with respect to transfer restrictions);

  .   use our reasonable best efforts to cause the registration statement to be
      declared effective under the Securities Act within 180 days after the
      issue date of the old notes;

  .   following the declaration of the effectiveness of the registration
      statement, promptly offer the new notes in exchange for surrender of the
      old notes; and

  .   keep the exchange offer open for not less than 30 days (or longer if
      required by applicable law) after the date notice of the exchange offer
      is mailed to the holders of the old notes.

   For each old note tendered to us pursuant to the exchange offer, we will
issue to the holder of such old note an new note having a principal amount
equal to that of the surrendered old note. Interest on each new note will
accrue from the last interest payment date on which interest was paid on the
old note surrendered in exchange therefor, or, if no interest has been paid on
such old note, from the date of its original issue.

   Under existing SEC interpretations, the new notes will be freely
transferable by holders other than our affiliates after the exchange offer
without further registration under the Securities Act if the holder of the new
notes represents to us in the exchange offer that it is acquiring the new notes
in the ordinary course of its business, that it has no arrangement or
understanding with any person to participate in the distribution of the new
notes and that it is not an affiliate of ours, as such terms are interpreted by
the SEC; provided, however, that broker-dealers receiving new notes in the
exchange offer will have a prospectus delivery requirement with respect to
resales of such new notes. The SEC has taken the position that such
participating broker-dealers may fulfill their prospectus delivery requirements
with respect to new notes (other than a resale of an unsold allotment from the
original sale of the old notes) with the prospectus contained in this
registration statement. Each broker-dealer that receives new notes for its own
account 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, must acknowledge that it will deliver a prospectus in connection
with any resale of such new notes. See "Plan of Distribution."

   Under the registration rights agreement, we are required to allow
participating broker-dealers and other persons, if any, with similar prospectus
delivery requirements to use the prospectus contained in this registration
statement in connection with the resale of such new notes for 180 days
following the effective date of such registration statement (or such shorter
period during which participating broker-dealers are required by law to deliver
such prospectus).

   A holder of old notes (other than certain specified holders) who wishes to
exchange old notes for new notes in the exchange offer will be required to
represent that any new notes to be received by it will be acquired in the

                                      22



ordinary course of its business and that at the time of the commencement of the
exchange offer it has no arrangement or understanding with any person to
participate in the distribution (within the meaning of the Securities Act) of
the new notes and that it is not an "affiliate" of ours, as defined in Rule 405
of the Securities Act, 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.

   In the event that:

  .   any change of law or in applicable interpretations thereof by the staff
      of the SEC do not permit us to effect an exchange offer;

  .   the exchange offer is not consummated within 210 days of the issue date
      of the old notes;

  .   in certain circumstances, certain holders of unregistered new notes so
      request; or

  .   in the case of any holder of old notes that participates in the exchange
      offer, such holder does not receive new notes on the date of the exchange
      that may be sold without restriction under state or federal securities
      laws (other than due solely to the status of such holder as an affiliate
      of ours or within the meaning of the Securities Act),

then in each case, we will (x) promptly deliver to the holders and the trustee
written notice thereof and (y) at our sole expense, (a) use our reasonable best
efforts to file a shelf registration statement covering resales of the old
notes within the time period set forth in the registration rights agreement,
(b) use our best efforts to keep effective the shelf registration statement
until the earliest of (1) two years after the issue date of the old notes, (2)
such time as all of the old notes covered by the shelf registration statement
are eligible to be sold to the public pursuant to Rule 144(k) of the Securities
Act or any successor statute.

   We will, in the event a shelf registration statement is filed, among other
things, provide to each holder for whom such shelf registration statement was
filed copies of the prospectus which is a part of the shelf registration
statement, notify each such holder when the shelf registration statement has
become effective and take certain other actions as are required to permit
unrestricted resales of the old notes or the new notes, as the case may be. A
holder selling such old notes or new notes pursuant to the shelf registration
statement generally would be required to be named as a selling security holder
in the related prospectus and to deliver a prospectus to purchasers, will be
subject to certain of the civil liability provisions under the Securities Act
in connection with such sales and will be bound by the provisions of the
registration rights agreement that are applicable to such holder (including
certain indemnification obligations).

   If we fail to meet the targets listed above, then additional interest shall
become payable in respect of the applicable old notes and new notes as follows:

      (1) if (A) neither the registration statement of which this prospectus
   forms a part nor a shelf registration statement covering resales of the old
   notes is filed with the SEC on or prior to the 90th day after the issue date
   of the old notes or (B) notwithstanding that we have consummated or will
   consummate the exchange offer, we are required to file a shelf registration
   statement and such shelf registration statement is not filed on or prior to
   the date required by the registration rights agreement, then, commencing on
   the day after either such required filing date, additional interest shall
   accrue on the principal amount of the notes at a rate of 0.50% per annum for
   the first 90 days immediately following each such filing date, such
   additional interest rate increasing by an additional 0.50% per annum at the
   beginning of each subsequent 90-day period; or

      (2) if (A) neither the registration statement of which this prospectus
   forms a part nor a shelf registration statement covering resales of the old
   notes is not declared effective by the SEC on or prior to the 180th day
   after the issue date of the old notes or (B) notwithstanding that we have
   consummated or will consummate the exchange offer, we are required to file a
   shelf registration statement and such shelf registration statement

                                      23



   is not declared effective by the SEC on or prior to the date required by the
   registration rights agreement, then, commencing on the day after either such
   required effective date, additional interest shall accrue on the principal
   amount of the notes at a rate of 0.50% per annum for the first 90 days
   immediately following each such date, such additional interest rate
   increasing by an additional 0.50% per annum at the beginning of each
   subsequent 90-day period; or

(3) if (A) we have not exchanged all validly tendered old notes in accordance
    with the terms of the exchange offer on or prior to the 210th day after the
    issue date of the old notes or (B) if applicable, the shelf registration
    statement covering resales of the old notes has been declared effective and
    such shelf registration statement ceases to be effective at any time prior
    to the second anniversary of the issue date of the old notes (other than
    after such time as all applicable notes have been disposed of thereunder or
    are eligible to be sold pursuant to Rule 144(k)), then additional interest
    shall accrue on the principal amount of the applicable notes at a rate of
    0.50% per annum for the first 90 days commencing on (x) the 210th day after
    the issue date of the old notes, in the case of (A) above, or (y) the day
    such shelf registration statement ceases to be effective, in the case of
    (B) above, such additional interest rate increasing by an additional 0.50%
    per annum at the beginning of each subsequent 90-day period;

provided, however, that the additional interest rate on the applicable old
notes and new notes may not accrue under more than one of the foregoing clauses
(1)-(3) at any one time and at no time shall the aggregate amount of additional
interest accruing exceed in the aggregate 1.0% per annum; provided, further,
however, that (a) upon the filing of the registration statement of which this
prospectus forms a part or a shelf registration statement (in the case of
clause (1) above), (b) upon the effectiveness of the registration statement of
which this prospectus forms a part or a shelf registration statement (in the
case of clause (2) above), or (c) upon the exchange of all validly tendered old
notes (in the case of clause (3) (A) above, or upon the effectiveness of the
shelf registration statement which had ceased to remain effective (in the case
of clause (3) (B) above), additional interest on the notes as a result of such
clause (or the relevant subclause thereof), as the case may be, shall cease to
accrue.

   Any amounts of additional interest due pursuant to clause (1), (2) or (3)
above will be payable in cash on the original interest payment dates.

   All references in the indenture governing the old notes and the new notes,
in any context, to any interest or other amount payable on or with respect to
the old notes or the new notes shall be deemed to include any additional
interest pursuant to the registration rights agreement.

   If we effect the exchange offer, we will be entitled to close the exchange
offer 30 days after the commencement thereof provided that we have accepted all
old notes theretofore validly tendered in accordance with the terms of the
exchange offer.

Background of the Exchange Offer

   An aggregate of $300,000,000 principal amount of 9.60% senior notes due 2012
are currently issued and outstanding. The maximum principal amount of new notes
that will be issued in exchange for old notes is $300,000,000. The terms of the
new notes and the old notes are identical in all material respects, except for
transfer restrictions and registration rights that do not apply to the new
notes, and will contain different administrative terms.

   The new notes will bear interest at a rate of 9.60% per year, payable
semiannually on March 15 and September 15 of each year, beginning on March 15,
2002. Interest on each new note will accrue from the last interest payment date
on which interest was paid on the old note surrendered in exchange therefor,
or, if no interest has been paid on such note, from the date of its original
issue. Holders of new notes will not receive any

                                      24



interest on old notes tendered and accepted for exchange. In order to exchange
your old notes for transferable new notes in the exchange offer, you will be
required to make the following representations:

  .   the new notes will be acquired in the ordinary course of your business;

  .   you have no arrangements with any person to participate in the
      distribution of the new notes; and

  .   you are not our "affiliate" as defined in Rule 405 of the Securities Act,
      or if you are an affiliate of ours, you will comply with the applicable
      registration and prospectus delivery requirements of the Securities Act.

   Upon the terms and subject to the conditions set forth in this prospectus
and in the letter of transmittal, we will accept for exchange any old notes
properly tendered and not validly withdrawn in the exchange offer, and the
exchange agent will deliver the new notes promptly after the expiration date of
the exchange offer. We expressly reserve the right to delay acceptance of any
of the tendered old notes or terminate the exchange offer and not accept for
exchange any tendered old notes not already accepted if any conditions set
forth under "--Conditions of the Exchange Offer" have not been satisfied or
waived by us or do not comply, in whole or in part, with any applicable law.

   If you tender your old notes, you 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 the old notes. We
will pay all charges, expenses and transfer taxes in connection with the
exchange offer, other than certain taxes described below under "--Transfer
Taxes."

Expiration Date; Extensions; Termination; Amendments

   The exchange offer will expire at 5:00 p.m., New York City time, on [      ]
, 2002, unless we extend it. We expressly reserve the right to extend the
exchange offer on a daily basis or for such period or periods as we may
determine in our sole discretion from time to time by giving oral, confirmed in
writing, or written notice to the exchange agent and by making a public
announcement by press release prior to 9:00 a.m., New York City time, on the
first business day following the previously scheduled expiration date. During
any extension of the exchange offer, all old notes previously tendered, not
validly withdrawn and not accepted for exchange will remain subject to the
exchange offer and may be accepted for exchange by us.

   To the extent we are legally permitted to do so, we expressly reserve the
absolute right, in our sole discretion, but are not required, to:

  .   waive any condition of the exchange offer; and

  .   amend any terms of the exchange offer.

   Any waiver or amendment to the exchange offer will apply to all old notes
tendered, regardless of when or in what order the old notes were tendered. If
we make a material change in the terms of the exchange offer or if we waive a
material condition of the exchange offer, we will disseminate additional
exchange offer materials, and we will extend the exchange offer to the extent
required by law.

   We expressly reserve the right, in our sole discretion, to terminate the
exchange offer if any of the conditions set forth under "--Conditions of the
Exchange Offer" exist. Any such termination will be followed promptly by a
public announcement. In the event we terminate the exchange offer, we will give
immediate notice to the exchange agent, and all old notes previously tendered
and not accepted for exchange will be returned promptly to the tendering
holders.

   In the event that the exchange offer is withdrawn or otherwise not
completed, new notes will not be given to holders of old notes who have validly
tendered their old notes.

                                      25



Resale of New Notes

   Based on interpretations of the SEC set forth in no-action letters issued to
third parties, we believe that new notes issued under the exchange offer in
exchange for old notes may be offered for resale, resold and otherwise
transferred by you without compliance with the registration and prospectus
delivery provisions of the Securities Act, if:

  .   you are not an "affiliate" of ours within the meaning of Rule 405 under
      the Securities Act;

  .   you are acquiring new notes in the ordinary course of your business; and

  .   you do not intend to participate in the distribution of the exchange
      notes.

   If you tender old notes in the exchange offer with the intention of
participating in any manner in a distribution of the new notes:

  .   you cannot rely on those interpretations of the SEC; and

  .   you must comply with the registration and prospectus delivery
      requirements of the Securities Act in connection with a secondary resale
      transaction, and the secondary resale transaction must be covered by an
      effective registration statement containing the selling security holder
      information required by Item 507 or 508, as applicable, of Regulation S-K
      under the Securities Act.

   Unless an exemption from registration is otherwise available, any security
holder intending to distribute new notes should be covered by an effective
registration statement under the Securities Act containing the selling security
holder's information required by Item 507 of Regulation S-K. This prospectus
may be used for an offer to resell, a resale or other re-transfer of new notes
only as specifically set forth in the section captioned "Plan of Distribution."
Only broker-dealers that acquired the new notes as a result of market-making
activities or other trading activities may participate in the exchange offer.
Each broker-dealer that receives new notes for its own account 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, must acknowledge that
it will deliver a prospectus in connection with any resale of the new notes.
Please read the section captioned "Plan of Distribution" for more details
regarding the transfer of new notes.

Acceptance of Old Notes for Exchange

   We will accept for exchange old notes validly tendered pursuant to the
exchange offer, or defectively tendered, if such defect has been waived by us,
after the later of:

  .   the expiration date of the exchange offer; and

  .   the satisfaction or waiver of the conditions specified below under
      "--Conditions of the Exchange Offer."

   We will not accept old notes for exchange subsequent to the expiration date
of the exchange offer. Tenders of old notes will be accepted only in principal
amounts equal to $1,000 or integral multiples thereof.

   We expressly reserve the right, in our sole discretion, to:

  .   delay acceptance for exchange of old notes tendered under the exchange
      offer, subject to Rule 14e-1 under the Exchange Act, which requires that
      an offeror pay the consideration offered or return the securities
      deposited by or on behalf of the holders promptly after the termination
      or withdrawal of a tender offer; or

  .   terminate the exchange offer and not accept for exchange any old notes
      not accepted for exchange, if any of the conditions set forth below under
      "--Conditions of the Exchange Offer" have not been satisfied or waived by
      us or in order to comply in whole or in part with any applicable law.

                                      26



   In all cases, new notes will be issued only after timely receipt by the
exchange agent of certificates representing old notes, or confirmation of
book-entry transfer, a properly completed and duly executed letter of
transmittal, or a manually signed facsimile thereof, and any other required
documents. For purposes of the exchange offer, we will be deemed to have
accepted for exchange validly tendered old notes, or defectively tendered old
notes with respect to which we have waived such defect, if, as and when we give
oral, confirmed in writing, or written notice to the exchange agent. Promptly
after the expiration date, we will deposit the new notes with the exchange
agent, who will act as agent for the tendering holders for the purpose of
receiving the new notes and transmitting them to the holders. The exchange
agent will deliver the new notes to holders of old notes accepted for exchange
after the exchange agent receives the new notes.

   If, for any reason, we delay acceptance for exchange of validly tendered old
notes or we are unable to accept for exchange validly tendered old notes, then
the exchange agent may, nevertheless, on its behalf, retain tendered old notes,
without prejudice to our rights described in this prospectus under the captions
"--Expiration Date; Extensions; Termination; Amendments," "--Conditions of the
Exchange Offer" and "--Withdrawal of Tenders," subject to Rule 14e-1 under the
Securities Exchange Act of 1934, which requires that an offeror pay the
consideration offered or return the securities deposited by or on behalf of the
holders thereof promptly after the termination or withdrawal of a tender offer.

   If any tendered old notes are not accepted for exchange for any reason, or
if certificates are submitted evidencing more old notes than those that are
tendered, certificates evidencing old notes that are not exchanged will be
returned, without expense, to the tendering holder, or, in the case of old
notes tendered by book-entry transfer into the exchange agent's account at a
book-entry transfer facility under the procedure set forth under "--Procedures
for Tendering Old Notes-Book-Entry Transfer," such old notes will be credited
to the account maintained at such book-entry transfer facility from which such
old notes were delivered, unless otherwise requested by such holder under
"--Special Delivery Instructions" in the letter of transmittal, promptly
following the exchange date or the termination of the exchange offer.
   Tendering holders of old notes exchanged in the exchange offer will not be
obligated to pay brokerage commissions or transfer taxes with respect to the
exchange of their old notes other than as described under the caption
"--Transfer Taxes" or as set forth in the letter of transmittal. We will pay
all other charges and expenses in connection with the exchange offer.

Procedures for Tendering Old Notes

   Any beneficial owner whose old notes are registered in the name of a broker,
dealer, commercial bank, trust company or other nominee or held through a
book-entry transfer facility and who wishes to tender old notes should contact
such registered holder promptly and instruct such registered holder to tender
old notes on such beneficial owner's behalf.

   Tender of Old Notes Held Through The Depository Trust Company.  The exchange
agent and The Depository Trust Company, or DTC, have confirmed that the
exchange offer is eligible for the DTC automated tender offer program.
Accordingly, DTC participants may electronically transmit their acceptance of
the exchange offer by causing DTC to transfer old notes to the exchange agent
in accordance with DTC's automated tender offer program procedures for
transfer. DTC will then send an agent's message to the exchange agent.

   The term "agent's message" means a message transmitted by DTC and received
by the exchange agent that forms part of the book-entry confirmation. The
agent's message states that DTC has received an express acknowledgment from the
participant in DTC tendering old notes that are the subject of that book-entry
confirmation, that the participant has received and agrees to be bound by the
terms of the letter of transmittal, and that we may enforce such agreement
against such participant. In the case of an agent's message relating to
guaranteed delivery, the term means a message transmitted by DTC and received
by the exchange agent, which states that DTC has received an express
acknowledgment from the participant in DTC tendering old notes that they have
received and agree to be bound by the notice of guaranteed delivery.

                                      27



   Tender of Old Notes Held in Physical Form.  For a holder to validly tender
old notes held in physical form:

  .   the exchange agent must receive at its address set forth in this
      prospectus a properly completed and validly executed letter of
      transmittal, or a manually signed facsimile thereof, together with any
      signature guarantees and any other documents required by the instructions
      to the letter of transmittal; and

  .   the exchange agent must receive certificates for tendered old notes at
      such address, or such old notes must be transferred pursuant to the
      procedures for book-entry transfer described above. A confirmation of
      such book-entry transfer must be received by the exchange agent prior to
      the expiration date of the exchange offer. A holder who desires to tender
      old notes and who cannot comply with the procedures set forth herein for
      tender on a timely basis or whose old notes are not immediately available
      must comply with the procedures for guaranteed delivery set forth below.

   LETTERS OF TRANSMITTAL AND OLD NOTES SHOULD BE SENT ONLY TO THE EXCHANGE
AGENT, AND NOT TO US OR TO ANY BOOK-ENTRY TRANSFER FACILITY.

   THE METHOD OF DELIVERY OF OLD NOTES, LETTERS OF TRANSMITTAL AND ALL OTHER
REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND RISK OF THE
HOLDER TENDERING OLD NOTES. DELIVERY OF SUCH DOCUMENTS WILL BE DEEMED MADE ONLY
WHEN ACTUALLY RECEIVED BY THE EXCHANGE AGENT. IF SUCH DELIVERY IS BY MAIL, WE
SUGGEST THAT THE HOLDER USE PROPERLY INSURED, REGISTERED MAIL WITH RETURN
RECEIPT REQUESTED, AND THAT THE MAILING BE MADE SUFFICIENTLY IN ADVANCE OF THE
EXPIRATION DATE OF THE EXCHANGE OFFER TO PERMIT DELIVERY TO THE EXCHANGE AGENT
PRIOR TO SUCH DATE. NO ALTERNATIVE, CONDITIONAL OR CONTINGENT TENDERS OF OLD
NOTES WILL BE ACCEPTED.

   Signature Guarantees.  A signature on a letter of transmittal or a notice of
withdrawal must be guaranteed by an eligible institution. Eligible institutions
include banks, brokers, dealers, municipal securities dealers, municipal
securities brokers, government securities dealers, government securities
brokers, credit unions, national securities exchanges, registered securities
associations, clearing agencies and savings associations. The signature need
not be guaranteed by an eligible institution if the old notes are tendered:

  .   by a registered holder who has not completed the box entitled "Special
      Registration Instructions" or "Special Delivery Instructions" on the
      letter of transmittal; or

  .   for the account of an eligible institution.

   If the letter of transmittal is signed by a person other than the registered
holder of any old notes, the old notes must be endorsed or accompanied by a
properly completed bond power. The bond power must be signed by the registered
holder as the registered holder's name appears on the old notes and an eligible
institution must guarantee the signature on the bond power.

   If the letter of transmittal or any old notes or bond powers are signed by
trustees, executors, administrators, guardians, attorneys-in-fact, officers of
corporations or others acting in a fiduciary or representative capacity, these
persons should so indicate when signing. Unless we waive this requirement, they
should also submit evidence satisfactory to us of their authority to deliver
the letter of transmittal.

   Book-Entry Transfer.  The exchange agent will seek to establish a new
account or utilize an existing account with respect to the old notes at DTC
promptly after the date of this prospectus. Any financial institution that is a
participant in the book-entry transfer facility system and whose name appears
on a security position listing it as the owner of the old notes may make
book-entry delivery of old notes by causing the book-entry transfer facility to
transfer such old notes into the exchange agent's account. HOWEVER, ALTHOUGH

                                      28



DELIVERY OF OLD NOTES MAY BE EFFECTED THROUGH BOOK-ENTRY TRANSFER INTO THE
EXCHANGE AGENT'S ACCOUNT AT A BOOK-ENTRY TRANSFER FACILITY, A PROPERLY
COMPLETED AND VALIDLY EXECUTED LETTER OF TRANSMITTAL, OR A MANUALLY SIGNED
FACSIMILE THEREOF, MUST BE RECEIVED BY THE EXCHANGE AGENT AT ITS ADDRESS SET
FORTH IN THIS PROSPECTUS ON OR PRIOR TO THE EXPIRATION DATE OF THE EXCHANGE
OFFER, OR ELSE THE GUARANTEED DELIVERY PROCEDURES DESCRIBED BELOW MUST BE
COMPLIED WITH. The confirmation of a book-entry transfer of old notes into the
exchange agent's account at a book-entry transfer facility is referred to in
this prospectus as a "book-entry confirmation." Delivery of documents to the
book-entry transfer facility in accordance with that book-entry transfer
facility's procedures does not constitute delivery to the exchange agent.

   Guaranteed Delivery.  If you wish to tender your old notes and:

  .   certificates representing your old notes are not lost but are not
      immediately available;

  .   time will not permit your letter of transmittal, certificates
      representing your old notes and all other required documents to reach the
      exchange agent on or prior to the expiration date of the exchange offer;
      or

  .   the procedures for book-entry transfer cannot be completed on or prior to
      the expiration date of the exchange offer;

you may tender your old notes if:

  .   your tender is made by or through an eligible institution; and

  .   on or prior to the expiration date of the exchange offer, the exchange
      agent has received from the eligible institution a properly completed and
      validly executed notice of guaranteed delivery, by manually signed
      facsimile transmission, mail or hand delivery, in substantially the form
      provided with this prospectus:

     .   setting forth your name and address, the registered number(s) of your
         old notes and the principal amount of old notes tendered;

     .   stating that the tender is being made by guaranteed delivery; and

  .   guaranteeing that, within three New York Stock Exchange trading days
      after the date of the notice of guaranteed delivery, the letter of
      transmittal or facsimile thereof, properly completed and validly
      executed, together with certificates representing the old notes, or a
      book-entry confirmation, and any other documents required by the letter
      of transmittal and the instructions thereto, will be deposited by the
      eligible institution with the exchange agent; and

  .   the exchange agent receives the properly completed and validly executed
      letter of transmittal or facsimile thereof with any required signature
      guarantees, together with certificates for all old notes in proper form
      for transfer, or a book-entry confirmation, and any other required
      documents, within three New York Stock Exchange trading days after the
      date of the notice of guaranteed delivery.

   Other Matters.  New notes will be issued in exchange for old notes accepted
for exchange only after timely receipt by the exchange agent of:

  .   certificates for, or a timely book-entry confirmation with respect to,
      your old notes;

  .   a properly completed and duly executed letter of transmittal or facsimile
      thereof with any required signature guarantees, or, in the case of a
      book-entry transfer, an agent's message; and

  .   any other documents required by the letter of transmittal.

   All questions as to the form of all documents and the validity, including
time of receipt, and acceptance of all tenders of old notes will be determined
by us, in our sole discretion, the determination of which shall be final

                                      29



and binding. ALTERNATIVE, CONDITIONAL OR CONTINGENT TENDERS OF OLD NOTES WILL
NOT BE CONSIDERED VALID. We reserve the absolute right to reject any or all
tenders of old notes that are not in proper form or the acceptance of which, in
our opinion, would be unlawful. We also reserve the right to waive any defects,
irregularities or conditions of tender as to particular old notes. Our
interpretation of the terms and conditions of the exchange offer, including the
instructions in the letter of transmittal, will be final and binding on all
parties.

   Unless waived by us, any defect or irregularity in connection with tenders
of old notes must be cured within the time that we determine. Tenders of old
notes will not be deemed to have been made until all defects and irregularities
have been waived by us or cured. Neither us, the exchange agent, or any other
person will be under any duty to give notice of any defects or irregularities
in tenders of old notes, or will incur any liability to holders for failure to
give any such notice.

   By signing or agreeing to be bound by the letter of transmittal, you will
represent to us that, among other things:

  .   any new notes that you receive will be acquired in the ordinary course of
      your business;

  .   you have no arrangement or understanding with any person or entity to
      participate in the distribution of the new notes;

  .   if you are not a broker-dealer, that you are not engaged in and do not
      intend to engage in the distribution of the new notes;

  .   if you are a broker-dealer that will receive new notes for your own
      account in exchange for old notes that were acquired as a result of
      market-making activities or other trading activities, that you will
      deliver a prospectus, as required by law, in connection with any resale
      of those new notes; and

  .   you are not an "affiliate" of ours, as defined in Rule 405 of the
      Securities Act, or, if you are an affiliate, you will comply with any
      applicable registration and prospectus delivery requirements of the
      Securities Act.

Withdrawal of Tenders

   Except as otherwise provided in this prospectus, you may withdraw your
tender of old notes at any time prior to the expiration date of the exchange
offer.

   For a withdrawal to be effective:

  .   the exchange agent must receive a written notice of withdrawal at the
      address set forth below under "--Exchange Agent"; or

  .   you must comply with the appropriate procedures of DTC's automated tender
      offer program system.

   Any notice of withdrawal must:

  .   specify the name of the person who tendered the old notes to be
      withdrawn; and

  .   identify the old notes to be withdrawn, including the principal amount of
      the old notes to be withdrawn.

   If certificates for old notes have been delivered or otherwise identified to
the exchange agent, then, prior to the release of those certificates, the
withdrawing holder must also submit:

  .   the serial numbers of the particular certificates to be withdrawn; and

  .   a signed notice of withdrawal with signatures guaranteed by an eligible
      institution, unless the withdrawing holder is an eligible institution.

                                      30



   If old notes have been tendered pursuant to the procedure for book-entry
transfer described above, any notice of withdrawal must specify the name and
number of the account at DTC to be credited with the withdrawn old notes and
otherwise comply with the procedures of DTC.

   We will determine all questions as to the validity, form and eligibility,
including time of receipt, of notices of withdrawal, and our determination
shall be final and binding on all parties. We will deem any old notes so
withdrawn not to have been validly tendered for exchange for purposes of the
exchange offer.

   We will return any old notes that have been tendered for exchange but that
are not exchanged for any reason to their holder without cost to the holder. In
the case of old notes tendered by book-entry transfer into the exchange agent's
account at DTC, according to the procedures described above, those old notes
will be credited to an account maintained with DTC for the old notes. This
return or crediting will take place as soon as practicable after withdrawal,
rejection of tender or termination of the exchange offer. You may re-tender
properly withdrawn old notes by following one of the procedures described under
"--Procedures for Tendering Old Notes" at any time on or prior to the
expiration date of the exchange offer.

Conditions of the Exchange Offer

   Despite any other term of the exchange offer, we will not be required to
accept for exchange any old notes and we may terminate or amend the exchange
offer as provided in this prospectus before accepting any old notes for
exchange if in our reasonable judgment:

  .   the exchange offer, or the making of any exchange by a holder of old
      notes, would violate applicable law or any applicable interpretation of
      the staff of the SEC;

  .   any action or proceeding has been instituted or threatened in any court
      or by or before any governmental agency with respect to the exchange
      offer that would reasonably be expected to materially impair our ability
      to proceed with the exchange offer or material adverse development has
      occured in any existing proceeding with respect to us or the subsidiary
      guarantors; or

  .   all governmental approvals we deem necessary for the consummation of the
      exchange offer shall not have occured.

   We will not be obligated to accept for exchange the old notes of any holder
that has not made to us:

  .   the representations described under the captions "--Procedures for
      Tendering Old Notes" and "Plan of Distribution"; and

  .   any other representations that may be reasonably necessary under
      applicable Securities and Exchange Commission rules, regulations or
      interpretations to make available to us an appropriate form for
      registration of the new notes under the Securities Act.

   We expressly reserve the right, at any time or at various times, to extend
the period of time during which the exchange offer is open. Consequently, we
may delay acceptance of any old notes by giving oral or written notice of an
extension to their holders. During an extension, all old notes previously
tendered will remain subject to the exchange offer, and we may accept them for
exchange. We will return any old notes that we do not accept for exchange for
any reason without expense to their tendering holder as promptly as practicable
after the expiration or termination of the exchange offer.

   We expressly reserve the right to amend or terminate the exchange offer and
to reject for exchange any old notes not previously accepted for exchange, upon
the occurrence of any of the conditions of the exchange offer specified above.
By public announcement we will give oral or written notice of any extension,
amendment, non-acceptance or termination to the holders of the old notes as
promptly as practicable. If we amend the exchange offer in a manner that we
consider material, we will disclose the amendment in the manner required by
applicable law.

                                      31



   These conditions are solely for our benefit and we may assert them
regardless of the circumstances that may give rise to them or waive them in
whole or in part at any time or at various times in our sole discretion. If we
fail at any time to exercise any of the foregoing rights, this failure will not
constitute a waiver of that right. Each of these rights will be deemed an
ongoing right that we may assert at any time or at various times.

   We will not accept for exchange any old notes tendered, and will not issue
new notes in exchange for any old notes, if at any time a stop order is
threatened or in effect with respect to the registration statement of which
this prospectus constitutes a part or the qualification of the indenture under
the Trust Indenture Act of 1939.

Transfer Taxes

   We will pay all transfer taxes, if any, applicable to the transfer and
exchange of old notes pursuant to the exchange offer. The tendering holder,
however, will be required to pay any transfer taxes, whether imposed on the
record holder or any other person, if:

  .   delivery of the new notes, or certificates for old notes for principal
      amounts not exchanged, are to be made to any person other than the record
      holder of the old notes tendered;

  .   tendered certificates for old notes are recorded in the name of any
      person other than the person signing any letter of transmittal; or

  .   a transfer tax is imposed for any reason other than the transfer and
      exchange of old notes under the exchange offer.

Consequences of Failure to Exchange

   If you do not exchange your old notes for new notes in the exchange offer,
you will remain subject to restrictions on transfer of the old notes:

  .   as set forth in the legend printed on the old notes as a consequence of
      the issuance of the new notes pursuant to the exemptions from, or in
      transactions not subject to, the registration requirements of the
      Securities Act and applicable state securities laws; and

  .   as otherwise set forth in the offering circular distributed in connection
      with the private offering of the old notes.

   In general, you may not offer or sell the old notes unless they are
registered under the Securities Act, or if the offer or sale is exempt from
registration under the Securities Act and applicable state securities laws.
Except as required by the registration rights agreement, we do not intend to
register resales of the old notes under the Securities Act. Based on
interpretations of the SEC, you may offer for resale, resell or otherwise
transfer new notes issued in the exchange offer without compliance with the
registration and prospectus delivery provisions of the Securities Act, provided
that:

  .   you are not an "affiliate" within the meaning of Rule 405 under the
      Securities Act;

  .   you acquired the new notes in the ordinary course of your business; and

  .   you have no arrangement or understanding with respect to the distribution
      of the new notes to be acquired in the exchange offer.

   If you tender old notes in the exchange offer for the purpose of
participating in a distribution of the new notes:

  .   you cannot rely on the applicable interpretations of the SEC; and

  .   you must comply with the registration and prospectus delivery
      requirements of the Securities Act in connection with a secondary resale
      transaction and that such a secondary resale transaction must be covered
      by an effective registration statement containing the selling security
      holder information required by Item 507 or 508, as applicable, of
      Regulation S-K under the Securities Act.

                                      32

Other

   Participation in the exchange offer is voluntary, and you should carefully
consider whether to exchange old notes for new notes. We urge you to consult
your financial and tax advisors in making your own decision on what action to
take.

   We may in the future seek to acquire untendered old notes in open market or
privately negotiated transactions, through subsequent exchange offers or
otherwise, on terms that may differ from the terms of the exchange offer. We
have no present plans to acquire any old notes that are not tendered in the
exchange offer or to file a registration statement to permit resales or any
untendered old notes.

                      DESCRIPTION OF CERTAIN INDEBTEDNESS

   The following description summarizes the material terms of our senior credit
facilities. The description may not contain all of the information that may be
important to you. To understand the agreements related to the senior credit
facilities fully, you should carefully read the agreements relating to the
senior credit facilities, copies of which are available as described under
"Where You Can Find More Information." The following description is qualified
in its entirety by reference to the agreements.

Senior Secured Credit Facility

  General

   In March 2002, we amended and restated our senior bank credit facility in
conjunction with the merger with Prize. The new credit facility provides for
total borrowings of $500 million, up from $225 million, and raises the
borrowing base from $160 million to $300 million. Additionally, the expiration
date of the facility was amended and extended to March 2006. After March 15,
2002, the new credit facility was used to (i) fund the cash component of the
merger consideration payable to the Prize shareholders, (ii) pay costs
associated with the merger, and (iii) for general corporate purposes.

   The new credit facility was treated as a new credit facility with respect to
the funds flow on the effective date of March 15, 2002. As such, the existing
balances on the old facility prior to March 15 were paid off with the proceeds
received on March 15, 2002. The original capitalized debt issuance costs of
$621,000, net of tax, related to the new credit facility were written off as an
extraordinary loss from early extinguishment of debt during the quarter ended
March 31, 2002. Upon the completion of the sale of the old notes and the Prize
merger, the availability under the bank financing was reduced, and is
approximately $300.0 million (the "new credit facility").

   The new credit facility will mature in three years with no required
principal payments until maturity, provided the outstanding principal does not
exceed the borrowing base determination established from time-to-time by the
lenders. Amounts under the new credit facility may be repaid and reborrowed
prior to the final maturity date.

   Availability under the new credit facility is governed by a borrowing base,
which is based on the value of certain of our and our subsidiaries' proved
reserves of oil and natural gas. The borrowing base is currently $300.0 million.

   Bankers Trust Company, a subsidiary of Deutsche Bank AG and an affiliate of
Deutsche Banc Alex. Brown Inc., is the administrative agent for the new credit
facility; an affiliate of CIBC World Markets Corp. will be the syndication
agent; and BNP Paribas will be the documentation agent.

  Guarantees; Security

   Each of our existing, wholly owned material subsidiaries (including those
added through the Prize merger), other than Hunter Butcher, Canvasback and
Redhead, are "restricted subsidiaries" under the new credit facility, as
certain future subsidiaries will be. These restricted subsidiaries guarantee
the new credit facility. The new credit facility and related guarantees, and
any permitted commodity or interest rate hedging agreements with any new credit
facility lender, are secured by a first priority lien on substantially all
assets owned now or in the future by Magnum Hunter and its restricted
subsidiaries. We have also pledged all of the stock of each of our restricted
subsidiaries.

  Interest; Fees

   The interest under the new credit facility is payable at rates per annum
equal to, at our option: (1) a base rate equal to higher of (a) Deutsche Bank
Trust Company Americas' prime rate or (b) the overnight federal funds rate

                                      34



plus 0.5%, plus, in each case, the applicable margin spread; or (2) the
Eurodollar rate plus the applicable margin spread. Unused commitment fees are
due quarterly.

   The applicable margin spread and the per annum percentage used to calculate
the unused commitment fee are determined by reference to a pricing schedule
which is based upon our usage of our borrowing base under the new credit
facility. The applicable margin ranges for eurodollar loans between 125 basis
points and 225 basis points, depending upon the pricing schedule. Undrawn
commitment fees generally range between 25 basis points and 37.5 basis points
per annum.

   Base rate loans may be prepaid at any time without a premium or penalty.
Eurodollar loans may be prepaid prior to the end of the applicable interest
period upon our reimbursement of certain breakage costs.

   We have the ability to issue letters of credit under the new credit facility.

  Covenants and Events of Default

   The new credit facility contains affirmative and negative covenants
customary for agreements of this type, including, among others, covenants
restricting our ability to (i) incur additional indebtedness, (ii) create liens
on our assets, (iii) make certain investments and loans, (iv) pay dividends and
other distributions, (v) consolidate, merge or sell assets, (vi) limitation on
hedging activities, and (vii) change the character of our business.

   We are also required to comply with certain financial tests and maintain
certain financial ratios. These financial tests and ratios include requirements
to maintain (i) a Maximum Leverage Ratio, (ii) a Minimum Interest Coverage
Ratio and (iii) a Minimum Current Ratio (in each case as defined in the new
credit facility).

   The new credit facility also includes customary events of default. Events of
default under the new credit facility include non-payment of principal,
interest or fees, violation of covenants, inaccuracy of representations and
warranties in any material respect, bankruptcy and insolvency events,
cross-defaults and a default in the event of a change of control. An event of
default under the facility will permit the lenders to accelerate the maturity
of the indebtedness under the facility, and may result in one or more
cross-defaults under other indebtedness of Magnum Hunter, including the notes
and our 10% Senior Notes. Similarly, a default under the indenture or the
indenture governing our 10% Senior Notes will constitute an event of default
under the new revolving credit facility.

10% Senior Notes due 2007

  General

   On May 29, 1997, we issued $140.0 million of 10% Senior Notes due June 1,
2007 in a private placement. We subsequently exchanged the notes with publicly
tradable notes pursuant to a registered exchange offer under the Securities
Act. In June 2001, we repurchased $10.5 million of the 10% Senior Notes.

  Interest

   Interest on the 10% Senior Notes generally accrues at the rate of 10% per
annum and is payable semi-annually in cash on each June 1 and December 1.

  Change in Control

   In the event of a change of control of Magnum Hunter, each holder of the 10%
Senior Notes will have the right to require Magnum Hunter to repurchase such
holder's 10% Senior Notes at a price equal to 101% of their principal amount,
plus accrued interest, if any, to the date of purchase.

                                      35



  Redemption

   The 10% Senior Notes will be redeemable, in whole or in part, at the option
of Magnum Hunter, on or at any time after June 1, 2002, at a declining premium.

  Covenants

   The 10% Senior Notes are general unsecured obligations of Magnum Hunter and
are pari passu in right of payment to existing and future senior indebtedness
and obligations of Magnum Hunter, including the new revolving credit facility
and the notes offered hereby. The indenture governing the 10% Senior Notes
contains certain covenants that limit the ability of Magnum Hunter and our
subsidiaries to, among other things, incur additional indebtedness, pay
dividends or make investments and certain other restricted payments, consummate
certain asset sales, enter into certain transactions with affiliates, incur
liens, pay dividends or make certain payments to our subsidiaries, merge or
consolidate with any other person or sell, assign, transfer, lease, convey or
otherwise dispose of all or substantially all of our assets. All of such
covenants are subject to significant qualification and exceptions.

                           DESCRIPTION OF NEW NOTES

   The old notes were issued under an indenture dated as of March 15, 2002 by
and among the Company, the Subsidiary Guarantors and Deutsche Bank Trust
Company Americas, formerly known as Bankers Trust Company, as Trustee (the
"Trustee"). Upon the issuance of the new notes, the Indenture will be subject
to and governed by the provisions of the Trust Indenture Act of 1939 as amended
(the "TIA").

   The new notes will be issued under the same Indenture as the old notes, and
the old notes, the new notes, and any additional notes issued from time to time
in accordance with the terms of the Indenture (if any) will constitute a single
series of debt securities under the Indenture. In the event that the exchange
offer is consummated, any old notes that remain outstanding after consummation
of the exchange offer, the private exchange notes and the new notes issued in
the exchange offer will vote together as a single class for purposes of
determining whether holders of the requisite percentage in outstanding
principal amount of new notes have taken certain actions or exercised certain
rights under the Indenture. Unless the context requires otherwise, for all
purposes of the Indenture and this "Description of New Notes," references to
the "notes" shall mean the new notes.

   The following summary of certain provisions of the Indenture does not
purport to be complete and is subject to, and is qualified in its entirety by
reference to, the TIA, and to all of the provisions of the Indenture, including
the definitions of certain terms therein and those terms made a part of the
Indenture by reference to the TIA as in effect on the date of the Indenture. A
copy of the form of Indenture may be obtained from the Company. The definitions
of certain capitalized terms used in the following summary are set forth below
under "--Certain Definitions." For purposes of this "Description of Notes"
section, references to the "Company" include only Magnum Hunter Resources, Inc.
and not its Subsidiaries.

   The new notes will be unsecured senior obligations of the Company ranking
pari passu in right of payment to all unsubordinated indebtedness of the
Company and will rank senior in right of payment to all subordinated
indebtedness of the Company. The Guarantees will be unsecured senior
obligations of the Subsidiary Guarantors and will rank pari passu in right of
payment to all unsubordinated indebtedness of the Subsidiary Guarantors and
will rank senior in right of payment to all subordinated indebtedness of the
Subsidiary Guarantors. However, the new notes will be effectively subordinated
to secured indebtedness of the Company and the Subsidiary Guarantors to the
extent of the value of the assets securing such indebtedness.

   The new notes will be issued in fully registered form only, without coupons,
in denominations of $1,000 and integral multiples thereof. Initially, the
Trustee will act as paying agent and registrar for the new notes. The new notes
may be presented for registration of transfer and exchange at the offices of
the registrar, which initially will be the Trustee's corporate trust office.
The Company may change any paying agent and registrar without notice to holders
of the new notes (the "Holders"). The Company will pay principal (and premium,
if any) on the new notes at the Trustee's corporate office in New York, New
York. At the Company's option, interest may be paid at the Trustee's corporate
trust office or by check mailed to the registered addresses of the Holders. Any
old notes that remain outstanding after the completion of the exchange offer,
together with the new notes issued in connection with the exchange offer, will
be treated as a single class of securities under the Indenture.

Principal, Maturity and Interest

   The notes will mature on March 15, 2012 and are limited in aggregate
principal amount to $300.0 million. Additional notes may be issued from time to
time, subject to the limitations set forth under the subheading "--Certain
Covenants--Limitation on Incurrence of Additional Indebtedness." Interest on
the notes will accrue at the rate of 9.60% per annum and will be payable
semi-annually in cash on each March 15 and September 15, commencing on
September 15, 2002, to the Persons who are registered Holders at the close of
business on the March 1 and September 1, respectively, immediately preceding
the applicable interest payment date. Interest on the notes will accrue from
and including the most recent date to which interest has been paid or, if no
interest has

                                      37



been paid, from and including the date of issuance. Interest will be computed
on the basis of a 360-day year comprised of twelve 30-day months.

   The notes will not be entitled to the benefit of any mandatory sinking fund.

Redemption

   Optional Redemption.  The notes will be redeemable, at the Company's option,
in whole at any time or in part from time to time, on and after March 15, 2007,
upon not less than 30 nor more than 60 days' notice, at the following
redemption prices (expressed as percentages of the principal amount thereof) if
redeemed during the 12-month period commencing on March 15 of the years set
forth below, plus, in each case, accrued interest, if any, thereon to the date
of redemption:



                         Year                Percentage
                         ----                ----------
                                          
                         2007...............  104.800%
                         2008...............  103.200%
                         2009...............  101.600%
                         2010 and thereafter  100.000%


   Optional Redemption upon Equity Offerings.  At any time, or from time to
time, on or prior to March 15, 2005, the Company may, at its option, use all or
a portion of the net cash proceeds of one or more Equity Offerings (as defined
below) to redeem up to 35% of the aggregate principal amount of the notes
issued under the Indenture at a redemption price equal to 109.600% of the
aggregate principal amount of the notes to be redeemed, plus accrued interest,
if any, thereon to the date of redemption; provided, that:

      (1)  at least 65% of the aggregate principal amount of notes issued under
   the Indenture remains outstanding immediately after giving effect to any
   such redemption; and

      (2)  the Company makes such redemption not more than 60 days after the
   consummation of any such Equity Offering.

Selection and Notice of Redemption

   In the event that less than all of the notes are to be redeemed at any time,
selection of such notes, or portions thereof, for redemption will be made by
the Trustee either:

      (1)  in compliance with the requirements of the principal national
   securities exchange, if any, on which the notes are listed; or,

      (2)  if the notes are not then listed on a national securities exchange,
   on a pro rata basis, by lot or by such other method as the Trustee shall
   deem fair and appropriate.

   No notes of a principal amount of $1,000 or less shall be redeemed in part.
If a partial redemption is made with the proceeds of an Equity Offering,
selection of the notes or portions thereof for redemption shall be made by the
Trustee only on a pro rata basis or on as nearly a pro rata basis as is
practicable (subject to the procedures of DTC), unless such method is otherwise
prohibited. Notice 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 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 a
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 applicable redemption date, interest will cease to accrue on notes or
portions thereof called for redemption as long as the Company has deposited
with the paying agent for the notes funds in satisfaction of the applicable
redemption price pursuant to the Indenture.

                                      38



Guarantees

   Each Subsidiary Guarantor will unconditionally guarantee, on an unsecured
senior basis, jointly and severally, to each Holder and the Trustee, the full
and prompt performance of the Company's obligations under the Indenture and the
notes, including the payment of principal of and interest on the notes (a
"Guarantee").

   The obligations of each Subsidiary Guarantor will be limited to the maximum
amount which, after giving effect to all other contingent and fixed liabilities
of such Subsidiary Guarantor 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 Guarantee or
pursuant to its contribution obligations under the Indenture will result in the
obligations of such Subsidiary Guarantor under its 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 that is a Restricted
Subsidiary without limitation, or with or to other Persons upon the terms and
conditions set forth in the Indenture. See "--Certain Covenants--Merger,
Consolidation and Sale of Assets." In the event all of the Capital Stock of a
Subsidiary Guarantor is sold by the Company and/or one or more of its
Restricted Subsidiaries and the sale complies with the provisions set forth in
"--Certain Covenants--Limitation on Asset Sales," such Subsidiary Guarantor's
Guarantee will be released.

   Separate financial statements of the Subsidiary Guarantors are not included
herein because such Subsidiary Guarantors are jointly and severally liable with
respect to the Company's obligations under the Indenture and the notes, and the
aggregate net assets, earnings and equity of the Subsidiary Guarantors and the
Company are substantially equivalent to the net assets, earnings and equity of
the Company on a consolidated basis.

Holding Company Structure

   The Company is a holding company for its Subsidiaries, with no material
operations of its own. Accordingly, the Company is dependent upon the
distribution of the earnings of its Subsidiaries, whether in the form of
dividends, advances or payments on account of intercompany obligations, to
service its debt obligations. In addition, the claims of the Holders of notes
are subject to the prior payment of all secured indebtedness of the Guarantors.
There can be no assurance that, after providing for all such secured claims,
there would be sufficient assets available from the Company and its
Subsidiaries to satisfy the claims of the Holders of notes.

Change of Control

   The Indenture provides that upon the occurrence of a Change of Control, each
Holder will have the right to require that the Company purchase all or a
portion of such Holder's notes pursuant to the offer described below (the
"Change of Control Offer"), at a purchase price equal to 101% of the principal
amount thereof, plus accrued interest, if any, thereon to the date of purchase.

   Within 30 days following the date upon which the Change of Control occurred,
the Company must send, by first class mail, a notice to each Holder, with a
copy to the Trustee, which notice shall govern the terms of the Change of
Control Offer. Such notice shall state, among other things, the purchase date,
which must be no earlier than 30 days nor later than 45 days from the date such
notice is mailed, other than as may be required by law (the "Change of Control
Payment Date"). A Change of Control Offer shall remain open for a period of 20
Business Days or such longer period as may be required by law. Holders electing
to have a note purchased pursuant to a Change of Control Offer will be required
to surrender the note, with the form entitled "Option of Holder to Elect
Purchase" on the reverse of the note completed, to the paying agent for the
notes at the address specified in the notice prior to the close of business on
the third Business Day prior to the Change of Control Payment Date.

   If a Change of Control Offer is made, there can be no assurance that the
Company will have available funds sufficient to pay the Change of Control
purchase price for all the notes that might be delivered by Holders

                                      39



seeking to accept the Change of Control Offer. In the event the Company is
required to purchase outstanding notes pursuant to a Change of Control Offer,
the Company expects that it would seek third party financing to the extent it
does not have available funds to meet its purchase obligations. However, there
can be no assurance that the Company would be able to obtain such financing.
Additionally, the occurrence of a Change of Control would constitute an event
of default under the existing Senior Credit Facility which would permit the
lenders thereunder to accelerate all indebtedness under the existing Senior
Credit Facility.

   Neither the Board of Directors of the Company nor the Trustee may waive the
covenant relating to the Company's obligation to make a Change of Control
Offer. Restrictions in the Indenture described herein on the ability of the
Company and its Restricted Subsidiaries to incur additional Indebtedness, to
grant Liens on their property, to make Restricted Payments and to make Asset
Sales may also make more difficult or discourage a takeover of the Company,
whether favored or opposed by the management of the Company. Consummation of
any such transaction in certain circumstances may require repurchase of the
notes, and there can be no assurance that the Company or the acquiring party
will have sufficient financial resources to effect such repurchase. Such
restrictions and the restrictions on transactions with Affiliates may, in
certain circumstances, make more difficult or discourage any leveraged buyout
of the Company by the management of the Company. While such restrictions cover
a wide variety of arrangements which have traditionally been used to effect
highly leveraged transactions, the Indenture may not afford the Holders of
notes protection in all circumstances from the adverse aspects of a highly
leveraged transaction, reorganization, restructuring, merger or similar
transaction.

   The Company 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 notes pursuant to a Change of Control Offer. To the extent that
the provisions of any securities laws or regulations conflict with the "Change
of Control" provisions of the Indenture, the Company shall comply with the
applicable securities laws and regulations and shall not be deemed to have
breached its obligations under the "Change of Control" provisions of the
Indenture by virtue thereof.

Certain Covenants

   The Indenture contains, among others, the following covenants:

   Limitation on Incurrence of Additional Indebtedness.  Other than Permitted
Indebtedness, the Company will not, and will not cause or permit any of its
Restricted Subsidiaries to, directly or indirectly, create, incur, assume,
guarantee, acquire, become liable, contingently or otherwise, with respect to,
or otherwise become responsible for payment of (collectively, "incur") any
Indebtedness (including, without limitation, Acquired Indebtedness); provided,
however, that if no Default or Event of Default shall have occurred and be
continuing at the time of or as a consequence of the incurrence of any such
Indebtedness, the Company and the Restricted Subsidiaries or any of them may
incur Indebtedness, in each case, if on the date of the incurrence of such
Indebtedness, after giving pro forma effect to the incurrence thereof and the
receipt and application of the proceeds therefrom, the Company's Consolidated
EBITDA Coverage Ratio would have been greater than 2.50 to 1.0.

   For purposes of determining any particular amount of Indebtedness under this
covenant, guarantees of Indebtedness otherwise included in the determination of
such amount shall not also be included.

   Indebtedness of a Person existing at the time such Person becomes a
Restricted Subsidiary (whether by merger, consolidation, acquisition of Capital
Stock or otherwise) or is merged with or into the Company or any Restricted
Subsidiary or which is secured by a Lien on an asset acquired by the Company or
a Restricted Subsidiary (whether or not such Indebtedness is assumed by the
acquiring Person) shall be deemed incurred at the time the Person becomes a
Restricted Subsidiary or at the time of the asset acquisition, as the case may
be.

   The Company will not, and will not permit any Subsidiary Guarantor to, incur
any Indebtedness which by its terms (or by the terms of any agreement governing
such Indebtedness) is subordinated in right of payment to

                                      40



any Indebtedness of the Company or such Subsidiary Guarantor, as the case may
be, other than the notes and the Guarantees unless such Indebtedness is also by
its terms (or by the terms of any agreement governing such Indebtedness) made
expressly subordinate in right of payment to the notes or the Guarantee of such
Subsidiary Guarantor, as the case may be, pursuant to subordination provisions
that are at least as favorable to the holders of the notes or such guarantee as
the subordination provisions of such Indebtedness (or agreement).

   Limitation on Restricted Payments.  The Company will not, and will not cause
or permit any of its Restricted Subsidiaries to, directly or indirectly:

      (1)  declare or pay any dividend or make any distribution (other than
   dividends or distributions made to the Company or any Restricted Subsidiary
   and other than any dividends or distributions payable solely in Qualified
   Capital Stock of the Company) on or in respect of shares of the Capital
   Stock of the Company or any Restricted Subsidiary to holders of such Capital
   Stock;

      (2)  purchase, redeem or otherwise acquire or retire for value any
   Capital Stock of the Company or any Restricted Subsidiary other than through
   the exchange therefor solely of Qualified Capital Stock of the Company;

      (3)  make any principal payment on, purchase, defease, redeem, prepay,
   decrease or otherwise acquire or retire for value, prior to any scheduled
   final maturity, scheduled repayment or scheduled sinking fund payment, any
   Indebtedness of the Company or a Subsidiary Guarantor that is subordinate or
   junior in right of payment to the notes or such Subsidiary Guarantor's
   Guarantee, as the case may be; or

      (4)  make any Investment (other than a Permitted Investment) (each of the
   foregoing actions set forth in clauses (1), (2), (3) and (4) being referred
   to as a "Restricted Payment");

if at the time of such Restricted Payment or immediately after giving effect
thereto,

          (i)  a Default or an Event of Default shall have occurred and be
       continuing;

          (ii)  the Company is not able to incur at least $1.00 of additional
       Indebtedness (other than Permitted Indebtedness) in compliance with
       "--Limitation on Incurrence of Additional Indebtedness" above; or

          (iii)  the aggregate amount of Restricted Payments (including such
       proposed Restricted Payment) made on or after January 1, 2002 (the
       amount expended for such purposes, if other than in cash, being the fair
       market value of such property as determined reasonably and in good faith
       by the Board of Directors of the Company) shall exceed the sum of:

      (u)  $25.0 million; plus

      (v)  50% of the cumulative Consolidated Net Income (or if cumulative
   Consolidated Net Income shall be a loss, minus 100% of such loss) of the
   Company earned on or after January 1, 2002 and on or prior to the last date
   of the Company's fiscal quarter immediately preceding such Restricted
   Payment (the "Reference Date") (treating such period as a single accounting
   period); plus

      (w)  100% of the aggregate net cash proceeds, or the fair market value of
   Property other than cash, received by the Company from any Person (other
   than a Restricted Subsidiary of the Company) from the issuance and sale on
   or after January 1, 2002 and on or prior to the Reference Date of Qualified
   Capital Stock of the Company; plus

      (x)  without duplication of any amounts included in clause (iii)(w)
   above, 100% of the aggregate net cash proceeds of any equity contribution
   received by the Company from a holder of the Company's Capital Stock
   (excluding, in the case of clauses (iii)(w) and (x), any net cash proceeds
   from an Equity Offering to the extent used to redeem the notes); plus

      (y)  an amount equal to the net reduction in Investments in Unrestricted
   Subsidiaries resulting from dividends, interest payments, repayments of
   loans or advances, or other transfers of cash or Properties (including
   transfers as a result of a merger or liquidation), in each case to the
   Company or to any Restricted

                                      41



   Subsidiary of the Company from Unrestricted Subsidiaries (but without
   duplication of any such amount included in calculating cumulative
   Consolidated Net Income of the Company), or from redesignations of
   Unrestricted Subsidiaries as Restricted Subsidiaries (in each case valued as
   provided in "--Limitation on Designation of Unrestricted Subsidiaries"
   below), not to exceed, in the case of any Unrestricted Subsidiary, the
   amount of Investments previously made by the Company or any Restricted
   Subsidiary in such Unrestricted Subsidiary and which was treated as a
   Restricted Payment under the Indenture; plus

      (z)  without duplication of the immediately preceding subclause (y), an
   amount equal to the lesser of the cost or net cash proceeds received upon
   the sale or other disposition of any Investment made on or after January 1,
   2002 which had been treated as a Restricted Payment (but without duplication
   of any such amount included in calculating cumulative Consolidated Net
   Income of the Company).

   Notwithstanding the foregoing, the provisions set forth in the immediately
preceding paragraph shall not prohibit:

      (1)  the payment of any dividend or redemption payment within 60 days
   after the date of declaration of such dividend or the applicable redemption
   if the dividend or redemption payment, as the case may be, would have been
   permitted on the date of declaration;

      (2)  if no Default or Event of Default shall have occurred and be
   continuing, the acquisition of any Capital Stock of the Company, either (i)
   solely in exchange for Qualified Capital Stock of the Company or (ii)
   through the application of net proceeds of a sale for cash (other than to a
   Restricted Subsidiary of the Company) of Qualified Capital Stock of the
   Company within 90 days before or within 5 days after such acquisition;

      (3)  if no Default or Event of Default shall have occurred and be
   continuing, the acquisition of any Indebtedness of the Company or Subsidiary
   Guarantor that is subordinate or junior in right of payment to the notes or
   such Subsidiary Guarantor's Guarantee, as the case may be, either (i) solely
   in exchange for Qualified Capital Stock of the Company, or (ii) through the
   application of net proceeds of a substantially concurrent sale for cash
   (other than to a Restricted Subsidiary of the Company) of (a) Qualified
   Capital Stock of the Company or (b) Refinancing Indebtedness;

      (4)  if no Default or Event of Default shall have occurred and be
   continuing, the payment of dividends on the TCW Preferred Stock; and

      (5)  the initial designation of Hunter Butcher International Limited
   Liability Company, Canvasback Energy, Inc. and Redhead Energy, Inc. as
   Unrestricted Subsidiaries (such designation shall be deemed to have occurred
   on December 31, 2001).

   In determining the aggregate amount of Restricted Payments on or after
January 1, 2002 in accordance with clause (iii) of the immediately preceding
paragraph, amounts expended pursuant to clauses (1), (2), (3) and (4) shall be
included in such calculation.

   Limitation on Asset Sales.  The Company will not, and will not cause or
permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless:

      (1)  the Company or the applicable Restricted Subsidiary, as the case may
   be, receives consideration at the time of such Asset Sale at least equal to
   the fair market value of the assets sold or otherwise disposed of (as
   determined in good faith by the Company's Board of Directors or senior
   management of the Company);

      (2)  at least 75% of the consideration received by the Company or such
   Restricted Subsidiary, as the case may be, from such Asset Sale shall be in
   the form of cash or Cash Equivalents and is received at the time of such
   disposition; and

                                      42



      (3)  upon the consummation of an Asset Sale, the Company shall apply, or
   cause such Restricted Subsidiary to apply, the Net Cash Proceeds relating to
   such Asset Sale within 360 days of receipt thereof either:

          (a)  to repay or prepay Indebtedness outstanding under the Senior
       Credit Facility and, if that Indebtedness is revolving credit
       Indebtedness, to correspondingly reduce the funding commitment under the
       Senior Credit Facility with respect to the revolving credit Indebtedness
       repaid or prepaid;

          (b)  to repay or prepay any Indebtedness of the Company that is
       secured by a Lien permitted to be incurred pursuant to "--Limitation on
       Liens" below;

          (c)  to make an investment in properties or assets that replace the
       properties or assets that were the subject of such Asset Sale or in
       properties or assets that will be used in the business of the Company
       and its Restricted Subsidiaries as existing on the Issue Date or in
       businesses reasonably related thereto ("Replacement Assets");

          (d)  to make an investment in Crude Oil and Natural Gas Related
       Assets;

          (e)  to repurchase of the Company's 10% Senior Notes due 2007
       pursuant to a net proceeds offer similar to the Net Proceeds Offer
       described below; or

          (f)  to make a combination of prepayment and investment permitted by
       the foregoing clauses (3)(a) through (3)(e).

   On the 361st day after an Asset Sale or such earlier date, if any, as the
Board of Directors of the Company determines not to apply the Net Cash Proceeds
relating to such Asset Sale as set forth in clauses (3)(a) through (3)(f) of
the immediately preceding paragraph (each a "Net Proceeds Offer Trigger Date"),
such aggregate amount of Net Cash Proceeds which have been received by the
Company or such Restricted Subsidiary but which have not been applied on or
before such Net Proceeds Offer Trigger Date as permitted in clauses (3)(a)
through (3)(f) of the immediately preceding paragraph (each a "Net Proceeds
Offer Amount") shall be applied by the Company or such Restricted Subsidiary,
as the case may be, to make an offer to purchase (a "Net Proceeds Offer") on a
date (the "Net Proceeds Offer Payment Date") not less than 30 nor more than 45
days following the applicable Net Proceeds Offer Trigger Date, from all Holders
and, to the extent required by the terms of any Pari Passu Indebtedness the
holders of such Pari Passu Indebtedness, on a pro rata basis, that principal
amount of notes (and Pari Passu Indebtedness) purchasable with the Net Proceeds
Offer Amount at a price equal to 100% of the principal amount of the notes (and
Pari Passu Indebtedness) to be purchased, plus accrued and unpaid interest, if
any, thereon to the date of purchase; provided, however, that if at any time
any non-cash consideration received by the Company or any Restricted
Subsidiary, as the case may be, in connection with any Asset Sale is converted
into or sold or otherwise disposed of for cash (other than interest received
with respect to any such non-cash consideration), then such conversion or
disposition shall be deemed to constitute an Asset Sale hereunder and the Net
Cash Proceeds thereof shall be applied in accordance with this covenant.

   The Company may defer the Net Proceeds Offer until there is an aggregate
unutilized Net Proceeds Offer Amount equal to or in excess of $10,000,000
resulting from one or more Asset Sales (at which time, the entire unutilized
Net Proceeds Offer Amount, and not just the amount in excess of $10,000,000,
shall be applied as required pursuant to this paragraph).

   Notwithstanding the first two paragraphs of this covenant, the Company and
its Restricted Subsidiaries will be permitted to consummate an Asset Sale
without complying with such paragraphs to the extent that:

      (1)  the consideration for such Asset Sale constitutes Replacement Assets
   and/or Crude Oil and Natural Gas Related Assets and/or the assumption of
   obligations secured by Liens that burden some or all of the assets being
   sold; provided that, in the case of any such assumption, (a) the Person
   assuming such obligations shall have no recourse with respect to such
   obligations to the Company or any of its Restricted Subsidiaries and (b) no
   assets of the Company or any of its Restricted Subsidiaries (other than
   those assets being sold) are subject to such Liens; and

                                      43



      (2)  such Asset Sale is for fair market value; provided, that at least
   75% of the total consideration received by the Company or any of its
   Restricted Subsidiaries in connection with any such Asset Sale shall be in
   the form of Replacement Assets, Crude Oil and Natural Gas Related Assets,
   the assumption of Liens described in clause (1) above, cash or Cash
   Equivalents and that any Net Cash Proceeds so received shall be subject to
   the provisions of clause (3) of the first paragraph and to the provisions of
   the second paragraph of this covenant.

   Notice of each Net Proceeds Offer will be mailed to the record Holders as
shown on the register of Holders within 30 days following the Net Proceeds
Offer Trigger Date, with a copy to the Trustee, and shall comply with the
procedures set forth in the Indenture. Upon receiving notice of the Net
Proceeds Offer, Holders may elect to tender their notes in whole or in part in
integral multiples of $1,000 in exchange for cash. To the extent Holders
properly tender notes and holders of Pari Passu Indebtedness property tender
such Indebtedness with an aggregate principal amount exceeding the Net Proceeds
Offer Amount, notes of tendering Holders and Pari Passu Indebtedness will be
purchased on a pro rata basis (based on principal amounts of notes and Pari
Passu Indebtedness tendered). A Net Proceeds Offer shall remain open for a
period of 20 Business Days or such longer period as may be required by law.

   The Company's ability to repurchase notes in a Net Proceeds Offer is
presently restricted by the terms of the Senior Credit Facility and may
hereafter be prohibited or otherwise limited by the terms of any then existing
borrowing arrangements and the Company's financial resources.

   The Company 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 notes pursuant to a Net Proceeds Offer. To the extent that the
provisions of any securities laws or regulations conflict with the "Asset
Sale"provisions of the Indenture, the Company shall comply with the applicable
securities laws and regulations and shall not be deemed to have breached its
obligations under the "Asset Sale"provisions of the Indenture by virtue thereof.

   Limitation on Dividend and Other Payment Restrictions Affecting Restricted
Subsidiaries.  The Company will not, and will not cause or permit any of its
Restricted Subsidiaries to, directly or indirectly, create or otherwise cause
or permit to exist or become effective any encumbrance or restriction on the
ability of any Restricted Subsidiary to:

      (1)  pay dividends or make any other distributions on or in respect of
   its Capital Stock;

      (2)  make loans or advances, or to pay any Indebtedness or other
   obligation owed, to the Company or any other Restricted Subsidiary;

      (3)  guarantee any Indebtedness or any other obligation of the Company or
   any Restricted Subsidiary; or

      (4)  transfer any of its property or assets to the Company or any other
   Restricted Subsidiary (each such encumbrance or restriction, a "Payment
   Restriction"),

except for such encumbrances or restrictions existing under or by reason of:

      (a)  applicable law;

      (b)  the Indenture or any other indentures governing Pari Passu
   Indebtedness; provided, however, that the provisions relating to such
   encumbrances or restriction contained in any such other indenture are no
   less favorable to the Holders in any material respect as determined by the
   Board of Directors of the Company in their reasonable and good faith
   judgment than the provisions relating to such encumbrances or restrictions
   contained in the Indenture;

      (c)  the Senior Credit Facility;

                                      44



      (d)  customary non-assignment provisions of any contract or any lease
   governing a leasehold interest of any Restricted Subsidiary;

      (e)  any instrument governing Acquired Indebtedness, which encumbrance or
   restriction is not applicable to such Restricted Subsidiary, or the
   properties or assets of such Restricted Subsidiary, other than the Person or
   the properties or assets of the Person so acquired;

      (f)  agreements existing on the Issue Date to the extent and in the
   manner such agreements are in effect on the Issue Date;

      (g)  customary restrictions with respect to a Restricted Subsidiary of
   the Company pursuant to an agreement that has been entered into for the sale
   or disposition of Capital Stock or assets of such Restricted Subsidiary to
   be consummated in accordance with the terms of the Indenture solely in
   respect of the assets or Capital Stock to be sold or disposed of;

      (h)  any instrument governing a Permitted Lien, to the extent and only to
   the extent such instrument restricts the transfer or other disposition of
   assets subject to such Permitted Lien; or

      (i)  an agreement governing Refinancing Indebtedness incurred to
   Refinance the Indebtedness issued, assumed or incurred pursuant to an
   agreement referred to in clause (b), (c), (e) or (f) above; provided,
   however, that the provisions relating to such encumbrance or restriction
   contained in any such Refinancing Indebtedness are no less favorable to the
   Holders in any material respect as determined by the Board of Directors of
   the Company in their reasonable and good faith judgment than the provisions
   relating to such encumbrance or restriction contained in the applicable
   agreement referred to in such clause (b), (c), (e) or (f).

   Limitation on Preferred Stock of Restricted Subsidiaries.  The Company will
not cause or permit any of its Restricted Subsidiaries to issue any Preferred
Stock of any Restricted Subsidiary (other than to the Company or to a
Restricted Subsidiary) or permit any Person (other than the Company or a
Restricted Subsidiary) to own any Preferred Stock of any Restricted Subsidiary.

   Limitation on Liens.  Other than Permitted Liens, the Company will not, and
will not cause or permit any of its Restricted Subsidiaries to, directly or
indirectly, create, incur, assume or permit or suffer to exist any Liens of any
kind against or upon any property or assets of the Company or any of its
Restricted Subsidiaries (whether owned on the Issue Date or acquired after the
Issue Date) unless:

      (1)  in the case of Liens securing Indebtedness that is expressly
   subordinate or junior in right of payment to the notes or any Guarantee, the
   notes or such Guarantee, as the case may be, are secured by a Lien on such
   property, assets or proceeds that is senior in priority to such Liens at
   least to the same extent as the notes are senior in priority to such
   Indebtedness; and

      (2)  in all other cases, the notes and the Guarantees are equally and
   ratably secured.

   Merger, Consolidation and Sale of Assets.  The Company will not, in a single
transaction or series of related transactions, consolidate or merge with or
into any Person, or sell, assign, transfer, lease, convey or otherwise dispose
of (or cause or permit any Restricted Subsidiary to sell, assign, transfer,
lease, convey or otherwise dispose of) all or substantially all of the
Company's assets (determined on a consolidated basis for the Company and its
Restricted Subsidiaries), whether as an entirety or substantially as an
entirety to any Person unless:

      (a)  either:

          (1)  the Company shall be the surviving or continuing corporation; or

          (2)  the Person (if other than the Company) formed by such
       consolidation or into which the Company is merged or the Person which
       acquires by sale, assignment, transfer, lease, conveyance or other
       disposition the properties and assets of the Company and its Restricted
       Subsidiaries substantially as an entirety (the "Surviving Entity"):

                                      45



             (x)  shall be a corporation organized and validly existing under
          the laws of the United States or any state thereof or the District of
          Columbia; and

             (y)  shall expressly assume, by supplemental indenture (in form
          and substance satisfactory to the Trustee), executed and delivered to
          the Trustee, the due and punctual payment of the principal of,
          premium, if any, and interest on all of the notes and the performance
          of every covenant of the notes, the Indenture and the Registration
          Rights Agreement on the part of the Company to be performed or
          observed;

      (b)  immediately after giving effect to such transaction and the
   assumption contemplated by clause (a)(2)(y) above (including giving effect
   to any Indebtedness incurred or anticipated to be incurred in connection
   with or in respect of such transaction), the Company or such Surviving
   Entity, as the case may be, shall be able to incur at least $1.00 of
   additional Indebtedness (other than Permitted Indebtedness) pursuant to
   "--Limitation on Incurrence of Additional Indebtedness" above;

      (c)  immediately after giving effect to such transaction and the
   assumption contemplated by clause (a)(2)(y) above (including, without
   limitation, giving effect to any Indebtedness incurred or anticipated to be
   incurred and any Lien granted in connection with or in respect of the
   transaction), no Default or Event of Default shall have occurred or be
   continuing; and

      (d)  the Company or the Surviving Entity, as the case may be, shall have
   delivered to the Trustee an officers' certificate and an opinion of counsel,
   each stating that such consolidation, merger, sale, assignment, transfer,
   lease, conveyance or other disposition and, if a supplemental indenture is
   required in connection with such transaction, such supplemental indenture
   complies with the applicable provisions of the Indenture and that all
   conditions precedent in the Indenture relating to such transaction have been
   satisfied; provided, however, that such counsel may rely, as to matters of
   fact, on a certificate or certificates of officers of the Company.

   For purposes of the foregoing, the transfer (by lease, assignment, sale or
otherwise, in a single transaction or series of transactions) of all or
substantially all of the properties or assets of one or more Restricted
Subsidiaries the Capital Stock of which constitutes all or substantially all of
the properties and assets of the Company, shall be deemed to be the transfer of
all or substantially all of the properties and assets of the Company.

   Upon any consolidation, combination or merger or any transfer of all or
substantially all of the assets of the Company in accordance with the
foregoing, in which the Company is not the continuing corporation, the
successor Person formed by such consolidation or into which the Company is
merged or to which such conveyance, lease or transfer is made shall succeed to,
and be substituted for, and may exercise every right and power of, the Company
under the Indenture and the notes with the same effect as if such surviving
entity had been named as such.

   Each Subsidiary Guarantor (other than any Subsidiary Guarantor whose
Guarantee is to be released in accordance with the terms of the Guarantee and
the Indenture in connection with any transaction complying with the provisions
of the Indenture described under "--Limitation on Asset Sales") will not, and
the Company will not cause or permit any Subsidiary Guarantor to, consolidate
with or merge with or into any Person other than the Company or another
Subsidiary Guarantor that is a Restricted Subsidiary unless:

      (1)  the entity formed by or surviving any such consolidation or merger
   (if other than the Subsidiary Guarantor) or to which such sale, lease,
   conveyance or other disposition shall have been made is a corporation or
   other legal entity organized and existing under the laws of the United
   States or any state thereof or the District of Columbia;

      (2)  such entity assumes by execution of a supplemental indenture all of
   the obligations of the Subsidiary Guarantor under its Guarantee;

      (3)  immediately after giving effect to such transaction, no Default or
   Event of Default shall have occurred and be continuing; and

                                      46



      (4)  immediately after giving effect to such transaction and the use of
   any net proceeds therefrom on a pro forma basis, the Company could satisfy
   the provisions of clause (b) of the first paragraph of this covenant.

   Any merger or consolidation of a Subsidiary Guarantor with and into the
Company (with the Company being the surviving entity) or another Subsidiary
Guarantor that is a Restricted Subsidiary need only comply with clause (d) of
the first paragraph of this covenant.

   Limitations on Transactions with Affiliates.  The Company will not, and will
not cause or permit any of its Restricted Subsidiaries to, directly or
indirectly, enter into, amend or permit or suffer to exist any transaction or
series of related transactions (including, without limitation, the purchase,
sale, lease or exchange of any property, the guaranteeing of any Indebtedness
or the rendering of any service) with, or for the benefit of, any of their
respective Affiliates (each an "Affiliate Transaction"), other than (x)
Affiliate Transactions permitted under the third paragraph of this covenant and
(y) Affiliate Transactions that are on terms that are fair and reasonable to
the Company or the applicable Restricted Subsidiary and are no less favorable
to the Company or the applicable Restricted Subsidiary than those that might
reasonably have been obtained in a comparable transaction at such time on an
arm's-length basis from a Person that is not an Affiliate of the Company or
such Restricted Subsidiary.

   All Affiliate Transactions (and each series of related Affiliate
Transactions which are similar or part of a common plan) involving aggregate
payments or other property with a fair market value in excess of $5,000,000
shall be approved by the Board of Directors of the Company, such approval to be
evidenced by a Board Resolution stating that such Board of Directors has
determined that such transaction complies with the foregoing provisions. If the
Company or any Restricted Subsidiary enters into an Affiliate Transaction (or a
series of related Affiliate Transactions related to a common plan) that
involves an aggregate fair market value of more than $15,000,000, the Company
shall, prior to the consummation thereof, obtain a favorable opinion as to the
fairness of such transaction or series of related transactions to the Company
or the relevant Restricted Subsidiary, as the case may be, from a financial
point of view, from an Independent Advisor and file the same with the Trustee.

   The requirements set forth in the first and second paragraphs of this
covenant shall not apply to:

      (1)  reasonable fees and compensation paid to and indemnity provided on
   behalf of, officers, directors, employees or consultants of the Company or
   any Restricted Subsidiary as determined in good faith by the Board of
   Directors or senior management of the Company or such Restricted Subsidiary,
   as the case may be;

      (2)  transactions exclusively between or among the Company and any of its
   Restricted Subsidiaries or exclusively between or among such Restricted
   Subsidiaries; provided, however, that such transactions are not otherwise
   prohibited by the Indenture; and

      (3)  Restricted Payments permitted by the Indenture.

   Limitation on Restricted and Unrestricted Subsidiaries.  As the Company or
any of its Subsidiaries forms or acquires Subsidiaries, each newly formed or
acquired Subsidiary shall be designated by the Company's Board of Directors as
a Restricted Subsidiary or an Unrestricted Subsidiary, provided that (1) any
Subsidiary of any already existing Unrestricted Subsidiary shall be (and shall
be deemed designated as) an Unrestricted Subsidiary, (2) subject to the
foregoing clause (1), any designation of an Unrestricted Subsidiary shall be
effective only if the Investment in that Subsidiary is made in compliance with
the covenant described above under "--Limitation on Restricted Payments," and
(3) subject to the foregoing clause (1), any failure by the Company's Board of
Directors to affirmatively make such a designation of a Subsidiary shall be
deemed a designation (in compliance with the Indenture) of such Subsidiary as a
Restricted Subsidiary.

                                      47



   After a Subsidiary of the Company has been designated as an Unrestricted
Subsidiary, the Board of Directors of the Company may, if no Default or Event
of Default would arise therefrom, redesignate such Unrestricted Subsidiary to
be a Restricted Subsidiary; provided that:

      (1)  any such redesignation shall be deemed to be an incurrence as of the
   date of such redesignation by the Company and its Restricted Subsidiaries of
   the Indebtedness (if any) of such redesignated Subsidiary for purposes of
   "--Limitation on Incurrence of Additional Indebtedness" above;

      (2)  unless such redesignated Subsidiary shall not have any Indebtedness
   outstanding, other than Indebtedness which would be Permitted Indebtedness,
   no such designation shall be permitted if immediately after giving effect to
   such redesignation and the incurrence of any such additional Indebtedness
   the Company could not incur $1.00 of additional Indebtedness (other than
   Permitted Indebtedness) pursuant to "--Limitation on Incurrence of
   Additional Indebtedness" above; and

      (3)  such Subsidiary assumes by execution of a supplemental indenture all
   of the obligations of a Subsidiary Guarantor under a Guarantee.

   After a Subsidiary of the Company has been designated as a Restricted
Subsidiary, the Board of Directors of the Company also may, if no Default or
Event of Default would arise therefrom, redesignate such Restricted Subsidiary
to be an Unrestricted Subsidiary if such redesignation is at that time
permitted under "--Limitation on Restricted Payments" above. Upon any such
permitted redesignation, such Restricted Subsidiary's Guarantee will be
released.

   Any such designation or redesignation of an Unrestricted Subsidiary by the
Board of Directors shall be evidenced to the Trustee by the filing with the
Trustee of a certified copy of the resolution of the Board of Directors giving
effect to such designation or redesignation and an Officers' Certificate
certifying that such designation or redesignation complied with the foregoing
conditions and setting forth in reasonable detail the underlying calculations.

   For purposes of the covenant described under "--Limitation on Restricted
Payments" above:

      (1)  an "Investment" shall be deemed to have been made at the time any
   Restricted Subsidiary is designated as an Unrestricted Subsidiary in an
   amount (proportionate to the Company's equity interest in such Subsidiary)
   equal to the net worth of such Restricted Subsidiary at the time that such
   Restricted Subsidiary is designated as an Unrestricted Subsidiary ("net
   worth" to be calculated based upon the fair market value of the assets of
   such Subsidiary as of any such date of designation); and

      (2)  any property transferred to or from an Unrestricted Subsidiary shall
   be valued at its fair market value at the time of such transfer.

   Notwithstanding the foregoing, the Board of Directors may not designate or
redesignate any Subsidiary of the Company to be an Unrestricted Subsidiary if,
after such designation or redesignation:

      (1)  the Company or any Restricted Subsidiary:

          (a)  provides credit support for, or a guarantee of, any Indebtedness
       of such Subsidiary (including any undertaking, agreement or instrument
       evidencing such Indebtedness); or

          (b)  is directly or indirectly liable for any Indebtedness of such
       Subsidiary; or

      (2)  such Subsidiary owns any Capital Stock of, or owns or holds any Lien
   on any property of, any Restricted Subsidiary which is not a Subsidiary of
   the Subsidiary to be so designated.

   Additional Subsidiary Guarantees.  If any of the Company's Restricted
Subsidiaries that is not a Subsidiary Guarantor is a guarantor of Pari Passu
Indebtedness or of the Company's 10% Senior Notes due 2007, then the Company
shall cause such Restricted Subsidiary to become a Subsidiary Guarantor. If the
Company or any of its Restricted Subsidiaries transfers or causes to be
transferred, in one transaction or a series of related

                                      48



transactions, any property to any Restricted Subsidiary that is not a
Subsidiary Guarantor, or if the Company or any of its Restricted Subsidiaries
shall organize, acquire or otherwise invest in or hold an Investment in another
Restricted Subsidiary, that causes the total consolidated assets owned by all
Restricted Subsidiaries that are not Subsidiary Guarantors to exceed in the
aggregate 2% of the total consolidated assets of the Company, then the Company
shall cause one or more of such transferees or acquired or other Restricted
Subsidiaries to become Subsidiary Guarantors to the extent necessary to cause
the total consolidated assets owned by all Restricted Subsidiaries that are not
Subsidiary Guarantors not to exceed in the aggregate 2% of the total
consolidated assets of the Company. If required to become a Subsidiary
Guarantor pursuant to either of the immediately preceding sentences, such
transferee or acquired or other Restricted Subsidiary shall:

      (1)  execute and deliver to the Trustee a supplemental indenture in form
   reasonably satisfactory to the Trustee pursuant to which such Restricted
   Subsidiary shall unconditionally guarantee all of the Company's obligations
   under the notes and the Indenture on the terms set forth in the Indenture;
   and

      (2)  deliver to the Trustee an opinion of counsel that such supplemental
   indenture has been duly authorized, executed and delivered by such
   Restricted Subsidiary and constitutes a legal, valid, binding and
   enforceable obligation of such Restricted Subsidiary. Thereafter, such
   Restricted Subsidiary shall be a Subsidiary Guarantor for all purposes of
   the Indenture.

   Limitation on Conduct of Business.  The Company will not, and will not
permit any of its Restricted Subsidiaries to, engage in the conduct of any
material business other than the Crude Oil and Natural Gas Business.

   Reports to Holders.  The Company will deliver to the Trustee within 15 days
after the filing of the same with the Commission, copies of the quarterly and
annual reports and of the information, documents and other reports, if any,
which the Company is required to file with the Commission pursuant to Section
13 or 15(d) of the Exchange Act. Notwithstanding that the Company may not be
subject to the reporting requirements of Section 13 or 15(d) of the Exchange
Act, the Company will file with the Commission, to the extent permitted, and
provide the Trustee and Holders with such annual reports and such information,
documents and other reports specified in Sections 13 and 15(d) of the Exchange
Act. The Company will also comply with the other provisions of 314(a) of the
TIA.

Events of Default

   The following events are defined in the Indenture as "Events of Default:"

      (1)  the failure to pay interest (including any Additional Interest) on
   the notes when the same becomes due and payable and the default continues
   for a period of 30 days;

      (2)  the failure to pay the principal on any notes, when such principal
   becomes due and payable, at maturity, upon redemption or otherwise
   (including the failure to make a payment to purchase notes tendered pursuant
   to a Change of Control Offer or a Net Proceeds Offer);

      (3)  a default in the observance or performance of any other covenant or
   agreement contained in the Indenture which default continues for a period of
   30 days after the Company receives written notice specifying the default
   (and demanding that such default be remedied) from the Trustee or the
   Holders of at least 25% of the outstanding principal amount of the notes
   (except in the case of a default with respect to observance or performance
   of any of the terms or provisions of "--Change of Control" or "Certain
   Covenants--Merger, Consolidation and Sale of Assets" or "--Limitation on
   Asset Sales" which will constitute an Event of Default with such notice
   requirement but without such passage of time requirement);

      (4)  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 of the Company or of any Restricted Subsidiary (or the payment
   of which is guaranteed by the Company or any Restricted Subsidiary), whether
   such Indebtedness now exists or is created after the Issue Date, which
   default (i) is caused by a failure to pay

                                      49



   principal of or premium, if any, or interest on such Indebtedness after any
   applicable grace period provided in such Indebtedness on the date of such
   default (a "payment default") or (ii) 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 has been a payment default or the
   maturity of which has been so accelerated, aggregates at least $10 million;

      (5)  one or more judgments in an aggregate amount in excess of $10
   million (unless covered by insurance by a reputable insurer as to which the
   insurer has not disclaimed coverage) shall have been rendered against the
   Company or any of its Restricted Subsidiaries and such judgments remain
   undischarged, unpaid and unstayed for a period of 60 days after such
   judgment or judgments become final and non-appealable;

      (6)  certain events of bankruptcy affecting the Company or any of its
   Significant Subsidiaries; or

      (7)  any of the Guarantees cease to be in full force and effect or any of
   the Guarantees are declared to be null and void or invalid and unenforceable
   or any of the Subsidiary Guarantors denies or disaffirms its liability under
   its Guarantees (other than by reason of release of a Subsidiary Guarantor in
   accordance with the terms of the Indenture).

   The Indenture provides that, if an Event of Default (other than an Event of
Default specified in clause (6) above relating to the Company) shall occur and
be continuing, the Trustee or the Holders of at least 25% in principal amount
of outstanding notes may declare the principal of, premium, if any, and accrued
and unpaid interest on all the notes to be due and payable by notice in writing
to the Company and the Trustee specifying the Event of Default and that it is a
"notice of acceleration," and the same shall become immediately due and
payable. If an Event of Default specified in clause (6) above relating to the
Company occurs and is continuing, then all unpaid principal of, and premium, if
any, and accrued and unpaid interest on all of the outstanding notes shall ipso
facto become and be immediately due and payable without any declaration or
other act on the part of the Trustee or any Holder.

   The Indenture provides that, at any time after a declaration of acceleration
with respect to the notes as described in the preceding paragraph, the Holders
of a majority in principal amount of the notes may rescind and cancel such
declaration and its consequences:

      (1)  if the rescission would not conflict with any judgment or decree;

      (2)  if all existing Events of Default have been cured or waived except
   nonpayment of principal or interest that has become due solely because of
   such acceleration;

      (3)  to the extent the payment of such interest is lawful, interest on
   overdue installments of interest and overdue principal, which has become due
   otherwise than by such declaration of acceleration, has been paid;

      (4)  if the Company has paid the Trustee its reasonable compensation and
   reimbursed the Trustee for its expenses, disbursements and advances; and

      (5)  in the event of the cure or waiver of an Event of Default of the
   type described in clause (6) of the description of Events of Default above,
   the Trustee shall have received an officers' certificate and an opinion of
   counsel that such Event of Default has been cured or waived; provided,
   however, that such counsel may rely, as to matters of fact, on a certificate
   or certificates of officers of the Company.

   No such rescission shall affect any subsequent Default or impair any right
consequent thereto.

   The Indenture provides that, at any time prior to the declaration of
acceleration of the notes, the Holders of a majority in principal amount of the
notes may waive any existing Default or Event of Default under the Indenture,
and its consequences, except a default in the payment of the principal of or
interest on any notes.

                                      50



   The Indenture provides that, Holders of the notes may not enforce the
Indenture or the notes except as provided in the Indenture and under the TIA.
During the existence of an Event of Default, the Trustee is required to
exercise such rights and powers vested in it under the Indenture and use the
same degree of care and skill in its exercise thereof as a prudent man would
exercise or use under the circumstances in the conduct of his own affairs.
Subject to the provisions of the Indenture relating to the duties of the
Trustee, whether or not an Event of Default shall occur and be continuing, the
Trustee is under no obligation to exercise any of its rights or powers under
the Indenture at the request, order or direction of any of the Holders, unless
such Holders have offered to the Trustee reasonable indemnity. Subject to all
provisions of the Indenture and applicable law, the Holders of a majority in
aggregate principal amount of the then outstanding notes have the right to
direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee or exercising any trust or power conferred on the
Trustee.

   Under the Indenture, the Company is required to provide an officers'
certificate to the Trustee promptly upon any such officer obtaining knowledge
of any Default or Event of Default (provided that such officers shall provide
such certification at least annually whether or not they know of any Default or
Event of Default) that has occurred and, if applicable, describe such Default
or Event of Default and the status thereof.

Legal Defeasance and Covenant Defeasance

   The Company may, at its option and at any time, elect to have its
obligations and the corresponding obligations of the Subsidiary Guarantors
discharged with respect to the outstanding notes ("Legal Defeasance"). Such
Legal Defeasance means that the Company shall be deemed to have paid and
discharged the entire indebtedness represented by the outstanding notes, and
satisfied all of its obligations with respect to the notes, except for:

      (1)  the rights of Holders to receive payments in respect of the
   principal of, premium, if any, and interest on the notes when such payments
   are due;

      (2)  the Company's obligations with respect to the notes concerning
   issuing temporary notes, registration of notes, mutilated, destroyed, lost
   or stolen notes and the maintenance of an office or agency for payments;

      (3)  the rights, powers, trust, duties and immunities of the Trustee and
   the Company's obligations in connection therewith; and

      (4)  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 and the Subsidiary Guarantors 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 with respect to the notes. In the
event Covenant Defeasance occurs, certain events (other than non-payment,
bankruptcy, receivership, reorganization and insolvency events) described under
"--Events of Default"will no longer constitute an Event of Default with respect
to the notes.

   In order to exercise either Legal Defeasance or Covenant Defeasance:

      (1)  the Company must irrevocably deposit with the Trustee, in trust, for
   the benefit of the Holders cash in United States dollars, non-callable
   United States government obligations, 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 notes on the stated date for payment thereof or on
   the applicable redemption date, as the case may be;

      (2)  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 the Trustee confirming that:

          (a)  the Company has received from, or there has been published by,
       the Internal Revenue Service a ruling; or

                                      51



          (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 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;

      (3)  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 the Trustee confirming that the Holders 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;

      (4)  no Default or Event of Default shall have occurred and be continuing
   on the date of 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;

      (5)  such Legal Defeasance or Covenant Defeasance shall not result in a
   breach or violation of, or constitute a default under the Indenture or any
   other agreement or instrument to which the Company or any of its Restricted
   Subsidiaries is a party or by which the Company or any of its Restricted
   Subsidiaries is bound;

      (6)  the Company shall have delivered to the Trustee an officers'
   certificate stating that the deposit was not made by the Company with the
   intent of preferring the Holders over any other creditors of the Company or
   with the intent of defeating, hindering, delaying or defrauding any other
   creditors of the Company or others;

      (7)  the Company shall have delivered to the Trustee an officers'
   certificate and an opinion of counsel, each stating that all conditions
   precedent provided for or relating to the Legal Defeasance or the Covenant
   Defeasance, as the case may be, have been complied with; provided, however,
   that such counsel may rely, as to matters of fact, on a certificate or
   certificates of officers of the Company;

      (8)  the Company shall 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; provided, however, that such counsel may rely, as to matters of
   fact, on a certificate or certificates of officers of the Company; and

      (9)  certain other customary conditions precedent are satisfied.

Satisfaction and Discharge

   The Indenture will be discharged and will cease to be of further effect
(except as to surviving rights of registration of transfer or exchange of the
notes, as expressly provided for in the Indenture) as to all outstanding notes
when:

      (1)  either:

          (a)  all the notes, theretofore authenticated and delivered (except
       lost, stolen or destroyed notes which have been replaced or paid and
       notes for whose payment money has theretofore been deposited in trust or
       segregated and held in trust by the Company and thereafter repaid to the
       Company or discharged from such trust) have been delivered to the
       Trustee for cancellation; or

          (b)  all notes not theretofore delivered to the Trustee for
       cancellation have become due and payable and the Company has irrevocably
       deposited or caused to be deposited with the Trustee funds in an amount
       sufficient to pay and discharge the entire Indebtedness on the notes not
       theretofore delivered to the Trustee for cancellation, for principal of,
       premium, if any, and interest on the notes to the date of deposit
       together with irrevocable instructions from the Company directing the
       Trustee to apply such funds to the payment thereof at maturity or
       redemption, as the case may be;

                                      52



      (2)  the Company has paid all other sums payable under the Indenture by
   the Company; and

      (3)  the Company has delivered to the Trustee an officers' certificate
   and an opinion of counsel stating that all conditions precedent under the
   Indenture relating to the satisfaction and discharge of the Indenture have
   been complied with; provided, however, that such counsel may rely, as to
   matters of fact, on a certificate or certificates of officers of the Company.

Modification of the Indenture

   From time to time, the Company, the Subsidiary Guarantors and the Trustee,
without the consent of the Holders, may amend the Indenture for certain
specified purposes, including curing ambiguities, defects or inconsistencies,
to comply with any requirements of the Commission in order to effect or
maintain the qualification of the Indenture under the TIA or to make any change
that would provide any additional benefit or rights to the Holders or that does
not adversely affect the rights of any Holder. In formulating its opinion on
such matters, the Trustee will be entitled to rely on such evidence as it deems
appropriate, including, without limitation, solely on an opinion of counsel;
provided, however, that in delivering such opinion of counsel, such counsel may
rely, as to matters of fact, on a certificate or certificates of officers of
the Company. Other modifications and amendments of the Indenture may be made
with the consent of the Holders of a majority in principal amount of the then
outstanding notes issued under the Indenture, except that, without the consent
of each Holder affected thereby, no amendment may:

      (1)  reduce the amount of notes whose Holders must consent to an
   amendment;

      (2)  reduce the rate of or change or have the effect of changing the time
   for payment of interest, including defaulted interest, on any notes;

      (3)  reduce the principal of or change or have the effect of changing the
   fixed maturity of any notes, or change the date on which any notes may be
   subject to redemption or repurchase, or reduce the redemption or repurchase
   price therefor;

      (4)  make any notes payable in money other than that stated in the notes;

      (5)  make any change in provisions of the Indenture protecting the right
   of each Holder to receive payment of principal of and interest on such Note
   on or after the due date thereof or to bring suit to enforce such payment,
   or permitting Holders of a majority in principal amount of notes to waive
   Defaults or Events of Default;

      (6)  amend, change or modify in any material respect the obligation of
   the Company to make and consummate a Change of Control Offer in the event of
   a Change of Control or make and consummate a Net Proceeds Offer with respect
   to any Asset Sale that has been consummated or modify any of the provisions
   or definitions with respect thereto;

      (7)  modify or change any provision of the Indenture or the related
   definitions affecting the ranking of the notes or any Guarantee in a manner
   which adversely affects the Holders; or

      (8)  release any Subsidiary Guarantor from any of its obligations under
   its Guarantee or the Indenture otherwise than in accordance with the terms
   of the Indenture.

Governing Law

   The Indenture will provide that the Indenture, the notes and the Guarantees
will be governed by, and construed in accordance with, the laws of the State of
New York but without giving effect to applicable principles of conflicts of law
to the extent that the application of the law of another jurisdiction would be
required thereby.

                                      53



The Trustee

   The Indenture provides that, except during the continuance of an Event of
Default, the Trustee will perform only such duties as are specifically set
forth in the Indenture. During the existence of an Event of Default, the
Trustee will exercise such rights and powers vested in it by the Indenture, and
use the same degree of care and skill in its exercise as a prudent man would
exercise or use under the circumstances in the conduct of his own affairs.

   The Indenture and the provisions of the TIA contain certain limitations on
the rights of the Trustee, should it become a creditor of the Company or a
Subsidiary Guarantor, to obtain payments of claims in certain cases or to
realize on certain property received in respect of any such claim as security
or otherwise. Subject to the TIA, the Trustee will be permitted to engage in
other transactions; provided, however, that if the Trustee acquires any
conflicting interest as described in the TIA, it must eliminate such conflict
or resign.

Certain Definitions

   Set forth below is a summary of certain of the defined terms to be used in

Subsidiary or at the time it merges or consolidates with the Company or any of

       petroleum engineers as of a date no earlier than the date of the

          industry practice, cause such revisions,

       in each of cases (iii) and (iv) calculated in accordance with Commission
       guidelines (utilizing the prices utilized in such year-end reserve
       report); provided, however, that, in the case of each of the
       determinations made pursuant to clauses (i) through (iv), such increases
       and decreases shall be as estimated by the Company's petroleum
       engineers, unless in the event that there is a Material Change as a

   Date;

      (2)  if interest on any Indebtedness actually incurred on the Transaction
   Date may optionally be determined at an interest rate based upon a factor of
   a prime or similar rate, a eurocurrency interbank offered rate, or other
   rates, then the interest rate in effect on the Transaction Date will be
   deemed to have been in effect during the Four Quarter Period; and


      (3)  notwithstanding clauses (1) and (2) above, interest on Indebtedness
   determined on a fluctuating basis, to the extent such interest is covered by
   agreements relating to Interest Swap Obligations, shall be deemed to accrue

   agreements.

           MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

   The following is a summary of certain United States federal income and
estate tax considerations relating to the purchase, ownership and disposition
of the new notes by holders thereof, and the exchange of the old notes by such
holder for new notes, but does not purport to be a complete analysis of all the
potential tax considerations relating thereto. This summary is based upon the
provisions of the Internal Revenue Code of 1986, as amended, or the Code,
regulations, rulings and judicial decisions as of the date hereof. These
authorities may be changed, possibly retroactively, so as to result in United
States federal income tax consequences different from those set forth below. We
have not sought any ruling from the Internal Revenue Service, or the IRS, or an
opinion of counsel with respect to the statements made and the conclusions
reached in the following summary, and there can be no assurance that the IRS
will agree with such statements and conclusions.

   This summary assumes that the new notes are held as capital assets and
holders are initial purchasers of the old notes who purchased the old notes at
their initial offering price. This summary does not address the tax
considerations arising under the laws of any foreign, state or local
jurisdiction. In addition, this discussion does not address tax considerations
applicable to a holder's particular circumstances or to holders that may be
subject to special tax rules, including, without limitation:

  .   holders subject to the alternative minimum tax;

  .   banks;

  .   tax-exempt organizations;

  .   insurance companies;

  .   dealers in securities or commodities;

  .   traders in securities that elect to use a mark-to-market method of
      accounting for their securities holdings;

  .   financial institutions;

  .   holders whose "functional currency" is not the U.S. dollar;

  .   U.S. expatriates;

  .   persons that will hold the new notes as a position in a hedging
      transaction, "straddle", "conversion transaction" or other risk reduction
      transaction; or

  .   persons deemed to sell the new notes under the constructive sale
      provisions of the Code.

   If a partnership holds new notes, the tax treatment of a partner in the
partnership will generally depend upon the status of the partner and the
activities of the partnership. If you are a partner of a partnership holding
our new notes, you should consult your tax advisor.

   THIS SUMMARY OF CERTAIN UNITED STATES FEDERAL TAX CONSIDERATIONS IS FOR
GENERAL INFORMATION ONLY AND IS NOT TAX ADVICE. YOU ARE URGED TO CONSULT YOUR
TAX ADVISOR WITH RESPECT TO THE APPLICATION OF UNITED STATES FEDERAL INCOME TAX
LAWS TO YOUR PARTICULAR SITUATION AS WELL AS ANY TAX CONSEQUENCES ARISING UNDER
THE UNITED STATES FEDERAL ESTATE OR GIFT TAX RULES OR UNDER THE LAWS OF ANY
STATE, LOCAL, FOREIGN OR OTHER TAXING JURISDICTION OR UNDER ANY APPLICABLE TAX
TREATY.

                                      71



Consequences to U.S. Holders

   The following is a summary of the United States federal tax consequences
that will apply to you if you are a U.S. holder of the new notes. Certain
consequences to "non-U.S. holders" of the new notes are described under
"--Consequences to Non-U.S. Holders" below. "U.S. holder" means a beneficial
owner of a new note that is:

  .   a citizen or resident of the United States;

  .   a corporation (or an entity that is treated as a corporation for U.S.
      federal tax purposes) created or organized in or under the laws of the
      United States or any political subdivision of the United States;

  .   an estate the income of which is subject to United States federal income
      taxation regardless of its source; or

  .   a trust that (1) is subject to the supervision of a court within the
      United States and that has one or more United States persons with
      authority to control all substantial decisions of the trust or (2) has a
      valid election in effect under applicable Treasury Regulations to be
      treated as a United States person.

  Exchange Offer

   The new notes should not differ materially in kind or extent from the old
notes and, as a result, your exchange of old notes for new notes should not
constitute a taxable disposition of the old notes for United States federal
income tax purposes. As a result, you should not recognize taxable income, gain
or loss on such exchange, your holding period for the new notes should
generally include the holding period for the old notes so exchanged, and your
adjusted tax basis in the new notes should generally be the same as your
adjusted tax basis in the old notes so exchanged.

  Payments of Interest

   Stated interest on the new notes will generally be taxable to you as
ordinary income at the time it is paid or accrued in accordance with your
method of accounting for tax purposes.

  Amortizable Bond Premium

   Generally, if you purchase a new note for an amount that exceeds the sum of
all amounts payable on the new note after the purchase date other than stated
interest, you will be considered to have purchased the new note at a premium.
You generally may elect to amortize the premium over the remaining term (or an
applicable call date as discussed below) of the new note on a yield to maturity
basis. The amortizable bond premium is treated as an offset to interest income
on the new note for United States federal income tax purposes. If you elect to
amortize bond premium, you must reduce your tax basis in the new note by the
deductions allowable for amortizable bond premium. An election to amortize bond
premium is revocable only with the consent of the IRS and applies to all
obligations owned or acquired by you on or after the first day of the taxable
year to which the election applies. We may redeem the new notes at any time, as
described in this prospectus under "Description of the New Notes--Redemption;
Optional Redemption." You will calculate the amount of amortizable bond premium
based on the amount payable at the applicable call date, but only if use of the
call date (in lieu of the stated maturity date) results in a smaller
amortizable bond premium for the period ending on the call date. If a new note
purchased at a premium is redeemed before its maturity and you have elected to
deduct the bond premium, you may be permitted to deduct any remaining
unamortized bond premium as an ordinary loss in the taxable year of the
redemption.

   If you do not elect to amortize bond premium, that premium will decrease the
gain or increase the loss you would otherwise recognize on disposition of the
new note.

  Market Discount

   If you purchase a new note for less than its principal amount, the
difference will be treated as a "market discount" for U.S. federal income tax
purposes unless the difference is a de minimis amount. Under the market

                                      72



discount rules, you will be required to treat any principal payment on a new
note, or any gain on its sale, exchange, retirement or other disposition, as
ordinary income to the extent of the accrued market discount that was not
previously included in gross income. If the new note is disposed of in a
non-taxable transaction (other than a non-recognition transaction described in
Section 1276 of the Code), accrued market discount will be taxable to you as
ordinary income as if you had sold the new note at its fair market value. In
addition, you may be required to defer, until the maturity of a new note or its
earlier disposition (including a non taxable transaction other than a
transaction described in Section 1276 of the Code), the deduction of all or a
portion of the interest expense in respect of any indebtedness incurred or
maintained to purchase or carry the new note. Market discount will be
considered to accrue on a straight-line basis during the period from the date
of acquisition to the maturity date of the new note unless you elect to accrue
market discount on a constant interest rate basis.

   You may elect to include market discount in gross income as the discount
accrues, either on a straight-line basis or on a constant interest rate basis.
This current inclusion election, once made, applies to all market discount
obligations acquired by you on or after the first day of the first taxable year
to which the election applies, and may not be revoked without the consent of
the IRS. If you make such an election, the foregoing rules with respect to the
recognition of ordinary income on sales and other dispositions of such debt
instruments and on any partial principal payment with respect to the new notes,
and the deferral of interest deductions on indebtedness incurred or maintained
to purchase or carry such debt instruments, would not apply.

  Sale, Exchange or Disposition of New Notes

   Subject to the discussion of the exchange offer above, you will generally
recognize gain or loss upon the sale, exchange or other disposition of a new
note equal to the difference between the amount realized upon the sale,
exchange or other disposition (less an amount attributable to any accrued
stated interest not previously included in income, which will be taxable as
interest income) and your adjusted tax basis in the new note. Your adjusted tax
basis in a new note will generally equal the amount you paid for the new note,
as adjusted by the bond premium and market discount rules described above. Any
gain or loss recognized on a disposition of the new note will be capital gain
or loss. If you are an individual and have held the new note for more than one
year, such capital gain will generally be subject to tax at a maximum rate of
20%. Your ability to deduct capital losses may be limited.

  Information Reporting and Backup Withholding

   In general, information reporting requirements will apply to certain
payments of principal and interest on the new notes and the proceeds of sale of
a new note unless you are an exempt recipient (such as a corporation). A 30%
backup withholding tax will apply to such payments if you fail to provide your
taxpayer identification number or certification of exempt status or have been
notified by the IRS that you are subject to backup withholding.

   Any amounts withheld under the backup withholding rules will generally be
allowed as a refund or a credit against your United States federal income tax
liability provided the required information is furnished to the IRS.

Consequences to Non-U.S. Holders

   The following is a summary of the United States federal tax consequences
that will apply to you if you are a non-U.S. holder of new notes. The term
"non-U.S. holder" means a beneficial owner of a new note that is not a U.S.
holder.

   Special rules may apply to certain non-U.S. holders such as "controlled
foreign corporations," "passive foreign investment companies" and "foreign
personal holding companies." Such entities should consult their own tax
advisors to determine the United States federal, state, local and other tax
consequences that may be relevant to them.

                                      73



  Payments of Interest

   The 30% United States federal withholding tax will not apply to any payment
to you of principal or interest on a new note provided that:

  .   you do not actually or constructively own 10% or more of the total
      combined voting power of all classes of our stock that are entitled to
      vote within the meaning of the Code and applicable Treasury Regulations;

  .   you are not a controlled foreign corporation that is related to us
      through stock ownership as provided in the Code and applicable Treasury
      Regulations;

  .   you are not a bank whose receipt of interest on the notes is in
      connection with an extension of credit made pursuant to a loan agreement
      entered into in the ordinary course of your business; and

  .   (a) you provide your name and address, and certify, under penalties of
      perjury, that you are not a United States person (which certification may
      be made on an IRS Form W-8BEN) or (b) a securities clearing organization,
      bank, or other financial institution that holds customers' securities in
      the ordinary course of its business holds the new note on your behalf and
      certifies, under penalties of perjury, that it has received IRS Form
      W-8BEN from you or from another qualifying financial institution
      intermediary, and provides a copy of the IRS Form W-8BEN. If you hold
      your new notes through certain foreign intermediaries or certain foreign
      partnerships, such foreign intermediaries or partnerships must also
      satisfy the certification requirements of applicable Treasury Regulations.

   If you cannot satisfy the requirements described above, payments of interest
will be subject to the 30% United States federal withholding tax, unless you
provide us with a properly executed (1) IRS Form W-8BEN claiming an exemption
from or reduction in withholding under the benefit of an applicable tax treaty
or (2) IRS Form W-8ECI stating that interest paid on the new note is not
subject to withholding tax because it is effectively connected with your
conduct of a trade or business in the United States. In addition, you may,
under certain circumstances, be required to obtain a United States Taxpayer
identification number ("TIN").

   If you are engaged in a trade or business in the United States and interest
on a new note is effectively connected with the conduct of that trade or
business, you will be required to pay United States federal income tax on that
interest on a net income basis (although you will be exempt from the 30%
withholding tax provided the certification requirement described above is met)
in the same manner as if you were a United States person as defined under the
Code. In addition, if you are a foreign corporation, you may be subject to a
branch profits tax equal to 30% (or lower applicable treaty rate) of your
earnings and profits for the taxable year, subject to adjustments, that are
effectively connected with your conduct of a trade or business in the United
States. For this purpose, interest that is effectively connected with your
conduct of a trade or business in the United States will be included in
earnings and profits.

   Generally, payments of interest to you would be subject to reporting
requirements, even though these payments are not subject to a 30% United States
federal withholding tax.

  Sale, Exchange or Disposition of New Notes

   Any gain realized upon the sale, exchange or other disposition of a new note
(except with respect to accrued and unpaid interest, which would be taxable as
described above) generally will not be subject to United States federal income
tax unless:

  .   that gain is effectively connected with your conduct of a trade or
      business in the United States;

  .   you are an individual who is present in the United States for 183 days or
      more in the taxable year of that disposition, and certain other
      conditions are met; or

  .   you are subject to Code provisions applicable to certain United States
      expatriates.

                                      74



   A holder described in the first bullet point above will be required to pay
United States federal income tax on the net gain derived from the sale, and if
such holder is a foreign corporation, it may also be required to pay a branch
profits tax at a 30% rate or a lower applicable treaty rate if so specified by
an applicable income tax treaty. A holder described in the second bullet point
above will be subject to a flat 30% United States federal income tax on the
gain derived from the sale, which may be offset by United States source capital
losses, even though the holder is not considered a resident of the United
States.

  United States Federal Estate Tax

   The United States federal estate tax will not apply to the new notes owned
by you at the time of your death, provided that (1) you do not own actually or
constructively 10% or more of the total combined voting power of all classes of
our voting stock (within the meaning of the Code and the Treasury Regulations)
and (2) interest on the new note would not have been, if received at the time
of your death, effectively connected with your conduct of a trade or business
in the United States.

  Information Reporting and Backup Withholding

   The amount of interest paid to you on the new note and the amount of tax
withheld, if any, will generally be reported to you and the IRS. You will
generally not be subject to backup withholding with respect to payments that we
make to you provided that we do not have actual knowledge that you are a United
States person and you have made appropriate certifications as to your foreign
status, or you otherwise establish an exemption.

   You will generally not be subject to backup withholding or information
reporting with respect to any payment of the proceeds of the sale of a new note
effected outside the United States by a foreign office of a foreign "broker"(as
defined in applicable Treasury Regulations). However, if such a broker:

  .   derives 50% or more of its gross income for certain periods from the
      conduct of a trade or business in the United States,

  .   is a controlled foreign corporation for United States federal income tax
      purposes, or

  .   is a foreign partnership that, at any time during its taxable year, has
      more than 50% of its income or capital interests owned by United States
      persons or is engaged in the conduct of a United States trade or business,

then you will be subject to information reporting, but not backup withholding
unless such broker has documentary evidence in its records that you are not a
United States person and certain other conditions are met, or you otherwise
establish an exemption. You will be subject to backup withholding and
information reporting with respect to any payment of the proceeds of a sale of
a new note effected by the United States office of a broker unless you properly
certify under penalties of perjury as to your foreign status and certain other
conditions are met or you otherwise establish an exemption.

   Any amounts withheld under the backup withholding rules will be allowed as a
refund or a credit against your United States federal income tax liability
provided the required information is furnished to the IRS.

                                      75



                             PLAN OF DISTRIBUTION

   Based on interpretations of the SEC set forth in no-action letters issued to
third parties, we believe that new notes issued under the exchange offer in
exchange for old notes may be offered for resale, resold and otherwise
transferred by you without compliance with the registration and prospectus
delivery provisions of the Securities Act, if:

  .   you are not an "affiliate"of ours within the meaning of Rule 405 under
      the Securities Act;

  .   you are acquiring new notes in the ordinary course of your business; and

  .   you do not intend to participate in the distribution of the new notes.

   If you tender old notes in the exchange offer with the intention of
participating in any manner in a distribution of the new notes:

  .   you cannot rely on those interpretations of the SEC; and

  .   you must comply with the registration and prospectus delivery
      requirements of the Securities Act in connection with a secondary resale
      transaction, and the secondary resale transaction must be covered by an
      effective registration statement containing the selling security holder
      information required by Item 507 or 508, as applicable, of Regulation S-K
      under the Securities Act.

   Each broker-dealer that receives new notes for its own account pursuant to
the exchange offer must acknowledge that it will deliver a prospectus in
connection with any resale of the new notes. 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
the old notes were acquired as a result of market-making activities or other
trading activities. We have agreed that, for a period of 180 days after the
exchange offer is completed, we will make this prospectus, as amended or
supplemented, available to any broker-dealer for use in connection with any
resale of new notes. In addition, until 90 days after the date of this
prospectus, all dealers effecting transactions in the new notes may be required
to deliver a prospectus.

   We will not receive any proceeds from any sales of the new notes by
broker-dealers. 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 methods of
resale, at market prices prevailing at the time of resale, at prices related to
those prevailing market prices or at negotiated prices. Any resale may be made
directly to the purchaser or to or through brokers or dealers who may receive
compensation in the form of commissions or concessions from the broker-dealer
and/or the purchasers of the new notes. Any broker-dealer that resells the new
notes that were received by it for its own account pursuant to the exchange
offer and any broker or dealer that participates in a distribution of the new
notes may be deemed to be an "underwriter" within the meaning of the Securities
Act and any profit on any resale of new notes and any commissions or
concessions received by any of those 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 180 days after the exchange offer is completed we will
promptly send additional copies of this prospectus and any amendment or
supplement to this prospectus to any broker-dealer that requests such documents
in the letter of transmittal. We have agreed to pay the expenses incident to
the exchange offer, other than commissions or concessions of any brokers or
dealers and the fees of any advisors or experts retained by the holders of old
notes, and will indemnify the holders of the old notes (including any
broker-dealers) against related liabilities, including liabilities under the
Securities Act.

                         GLOSSARY OF OIL AND GAS TERMS

   "Bbl" or "barrel" means 42 U.S. gallons.

   "Bcf" means billion cubic feet of natural gas.

   "Bcfe" means billion equivalent cubic feet of natural gas, calculated by
converting oil to equivalent Mcf at a ratio of 6 Mcf of natural gas to 1 Bbl of
oil.

   "BOE" means equivalent barrels of oil, calculated at a ratio of 6 Mcf of
natural gas to 1 Bbl of oil.

   "Completion" means the installation of permanent equipment for the
production of oil or gas.

   "Exploratory well" means a well drilled to find and produce oil in an
unproved area, to find a new reservoir in a field previously found to be
productive of oil or gas in another reservoir, or to extend a known reservoir.

   "Gross," when used with respect to acres or wells, refers to the total acres
or wells in which Magnum Hunter has a working interest.

   "Infill drilling" means the drilling of an additional well or wells provided
for by an existing spacing order to more adequately drain a reservoir.

   "MBbls" means thousand barrels.

   "Mcf" means thousand cubic feet.

   "Mcfe" means thousand equivalent cubic feet of natural gas, calculated by
converting oil to equivalent Mcf at a ratio of 6 Mcf to 1 Bbl of oil.

   "MMcf" means million cubic feet of natural gas.

   "MMcfe" means million cubic feet equivalent, determined using the ratio of 6
Mcf of natural gas to 1 Bbl of oil.

   "Net," when used with respect to acres or wells, refers to gross acres of
wells multiplied, in each case, by the percentage working interest owned by
Magnum Hunter.

   "Net revenue interest" means a share of the working interest that does not
bear any portion of the expense of drilling and completing a well and that
represents the holder's share of production after satisfaction of all royalty,
overriding royalty, oil payments and other nonoperating interests.

   "Oil" means crude oil or condensate.

   "Operator" means the individual or company responsible for the exploration,
development, and production of an oil or gas well or lease.

   "Productive Well" means a well that is producing oil or gas or that is
capable of production in paying quantities.

   "Producing reserves" means proved developed reserves that can be expected to
be recovered from currently producing zones under the continuation of present
operating methods.

                                      79



   "Proved developed reserves" means reserves that can be expected to be
recovered through existing wells with existing equipment and operating methods.
Additional oil and gas expected to be obtained through the application of fluid
injection or other improved recovery techniques for supplementing the natural
forces and mechanisms of primary recovery will be included as "proved developed
reserves" only after testing by a pilot project or after the operation of an
installed program has confirmed through production response that increased
recovery will be achieved.

   "Proved reserves" means the 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, i.e., prices and costs as of
the date the estimate is made. Prices include consideration of changes in
existing prices provided only by contractual arrangements, but not on
escalations based upon future conditions.

      i.  Reservoirs are considered proved if economic producibility is
   supported by either actual production or conclusive formation test. The area
   of a reservoir considered proved includes (A) that portion delineated by
   drilling and defined by gas-oil and/or oil-water contacts, if any; and (B)
   the immediately adjoining portions not yet drilled, but which can be
   reasonably judged as economically productive on the basis of available
   geological and engineering data. In the absence of information on fluid
   contacts, the lowest known structural occurrence of hydrocarbons controls
   the lower proved limit of the reservoir.

      ii.  Reserves which can be produced economically through application of
   improved recovery techniques (such as fluid injection) are included in the
   "proved" classification when successful testing by a pilot project, or the
   operation of an installed program in the reservoir, provides support for the
   engineering analysis on which the project or program was based.

      iii.  Estimates of proved reserves do not include the following: (A) oil
   that may become available from known reservoirs but is classified separately
   as "indicated additional reserves"; (B) crude oil, natural gas, and natural
   gas liquids, the recovery of which is subject to reasonable doubt because of
   uncertainty as to geology, reservoir characteristics, or economic factors;
   (C) crude oil, natural gas, and natural gas liquids that may occur in
   undrilled prospects; and (D) crude oil, natural gas, and natural gas liquids
   that may be recovered from oil shales, coal, gilsonite and other such
   sources.

   "PV-10" means the present value of estimated future revenues to be generated
from the production of proved reserves calculated in accordance with SEC
guidelines, net of estimated production and future development costs but before
deducting federal income taxes, using prices and costs as of the date of
estimation without future escalation, without giving effect to non-property
related expenses such as general and administrative expenses, debt service and
depreciation, depletion and amortization, and discounted using an annual
discount rate of 10%.

   "Recompletion" means the completion for production of an existing well bore
in another formation or producting horizon from that in which the well has been
previously completed.

   "Reserve life" means the estimated productive life of a proved reservoir
based upon the economic limit of such reservoir producing hydrocarbons in
paying quantities assuming certain price and cost parameters. For purposes of
this document, reserve life is calculated by dividing the proved reserves (on
an Mcfe basis) at the end of the period by projected production volumes for the
next 12 months.

   "Reserves" means proved reserves.

   "Royalty" means an interest in an oil and gas lease that gives the owner of
the interest the right to receive a portion of the production from the leased
acreage (or of the proceeds of the sale thereof), but generally does not
require the owner to pay any portion of the costs of drilling or operating the
wells on the leased acreage. Royalties may be either landowner's royalties,
which are reserved by the owner of the leased acreage at the time

                                      80



the lease is granted, or overriding royalties, which are usually reserved by an
owner of the leasehold in connection with a transfer to a subsequent owner.

   "3-D seismic" means seismic data that are acquired and processed to yield a
three-dimensional picture of the subsurface.

   "Working interest" means an interest in an oil and gas lease that gives the
owner of the interest the right to drill for and produce oil and gas on the
leased acreage and requires the owner to pay a share of the costs of drilling
and production operations. The share of production to which a working interest
owner is entitled will always be smaller than the share of costs that the
working interest owner is required to bear, with the balance of the production
accruing to the owners of royalties. For example, the owner of a 100% working
interest in a lease burdened only by a landowner's royalty of 12.5% would be
required to pay 100% of the costs of a well but would be entitled to retain
87.5% of the production.

   "Workover" means operations on a producing well to restore or increase
production.

                                      81

                                    PART II

                    INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20.  Indemnification of Directors and Officers.

   Set forth below is a description of certain provisions of the articles of
incorporation and bylaws of us and the corporate guarantors and the partnership
agreements of our non-corporate guarantors. These descriptions are intended as
a summary only and are qualified in their entirety by the appropriate articles
of incorporation, bylaws, partnership agreements and state law.

   (a)  Magnum Hunter

   The General Corporation Law of Nevada permits provisions in the articles,
by-laws or resolutions approved by shareholders which limit liability of
directors for breach of fiduciary duty in certain specified circumstances.
Nevada law permits indemnification if a director or officer acts in good faith
in a manner reasonably believed to be in, or not opposed to, the best interests
of the corporation. A director or officer must be indemnified as to any matter
in which he successfully defends himself. Indemnification is prohibited as to
any matter in which the director or officer is adjudged liable.

   The articles of incorporation of Magnum Hunter provide, consistent with the
provisions of the Nevada Revised Statutes, that no director of the Magnum
Hunter will be personally liable to Magnum Hunter or any of its stockholders
for monetary damages arising from the director's breach of fiduciary duty as a
director. This does not apply, however, with respect to any action for unlawful
payments of dividends, stock purchases or redemptions, nor does it apply if the
director has acted in a manner involving intentional misconduct, fraud, or a
knowing violation of law or, in failing to act, has acted in a manner involving
intentional misconduct, fraud, or a knowing violation of law. The provisions of
the articles of incorporation eliminating liability of directors for monetary
damages do not affect the standard of conduct to which directors must adhere,
nor do such provisions affect the availability of equitable relief. In
addition, such limitations on personal liability do not affect the availability
of monetary damages under claims based on federal law.

   (b)  The Guarantors

   The Texas Business Corporation Act empowers corporations incorporated in
Texas to indemnify any person who was, is or is threatened to be made a named
defendant or respondent in a proceeding because the person is or was a director
or officer against judgments, penalties (including excise and similar taxes),
fines, settlements and reasonable expenses (including court costs and
attorneys' fees) actually incurred by the person in connection with the
proceeding. Each Texas corporation is required pursuant to the Texas Business
Corporation Act to indemnify a director or officer against reasonable expenses
(including court costs and attorneys' fees) incurred by him in connection with
a proceeding in which he is a named defendant or respondent because he is or
was a director or officer if he has been wholly successful, on the merits or
otherwise, in the defense of the proceeding. The Texas Business Corporation Act
provides that indemnification pursuant to its provisions is not exclusive of
other rights of indemnification to which a person may be entitled under any
bylaw, agreement, vote of shareholders or disinterested directors, or otherwise.

   The articles of incorporation of Gruy Petroleum Management Co. provide,
consistent with the provisions of the Texas Business Corporation Act, that no
director of the Gruy Petroleum Management Co. will be personally liable to Gruy
Petroleum Management Co. or any of its shareholders for monetary damages
arising from the director's breach of fiduciary duty as a director. This does
not apply, however, with respect to any action for unlawful payments of
dividends, stock purchases or redemptions, nor does it apply if the director
has acted in a manner involving intentional misconduct, fraud, or a knowing
violation of law or, in failing to act, has acted in a

                                     II-1



manner involving intentional misconduct, fraud, or a knowing violation of law.
The provisions of the articles of incorporation eliminating liability of
directors for monetary damages do not affect the standard of conduct to which
directors must adhere, nor do such provisions affect the availability of
equitable relief. In addition, such limitations on personal liability do not
affect the availability of monetary damages under claims based on federal law.

   The bylaws of each of Magnum Hunter Production, Inc., Gruy Petroleum
Management Co., Hunter Gas Gathering, Inc., Conmag Energy Corporation and
Trapmar Properties, Inc. provide for indemnification of the directors and
officers of each such respective corporation to the fullest extent permitted by
the Texas Business Corporation Act.

   Section 102(b) of the Delaware General Corporation Law allows a corporation
to include in its certificate of incorporation a provision to eliminate or
limit the personal liability of a director to the registrant or its
stockholders for monetary damages for breach of fiduciary duty as a director,
except in cases where the director breached his or her duty of loyalty to the
registrant or its stockholders, failed to act in good faith, engaged in
intentional misconduct or a knowing violation of a law, willfully or
negligently authorized the unlawful payment of a dividend or approved an
illegal stock repurchase (as provided in Section 174 of the Delaware General
Corporation Law) or obtained an improper personal benefit.

   The certificate of incorporation of each of Pintail Energy, Inc., PEC
(Delaware), Inc., Prize Operating Company, the sole general partner of Prize
Energy Resources, L.P. and Oklahoma Gas Processing, Inc. provide, consistent
with the provisions of the Delaware General Corporation Law, that no director
of each respective corporation will be personally liable to the respective
corporation or any of their respective stockholders for monetary damages
arising from the director's breach of fiduciary duty as a director. This does
not apply, however, with respect to any action for unlawful payments of
dividends, stock purchases or redemptions, nor does it apply if the director
(i) has breached his duty of loyalty to the respective corporation and its
respective stockholders; (ii) does not act or, in failing to act, has not acted
in good faith; (iii) has acted in a manner involving intentional misconduct or
a knowing violation of law or, in failing to act, has acted in a manner
involving intentional misconduct or a knowing violation of law; or (iv) has
derived an improper personal benefit. The provisions of each certificate of
incorporation eliminating liability of directors for monetary damages do not
affect the standard of conduct to which directors must adhere, nor do such
provisions affect the availability of equitable relief. In addition, such
limitations on personal liability do not affect the availability of monetary
damages under claims based on federal law.

Item 21(a).  Exhibits.

   The information required by this Item 21(a) is set forth in the Index to
Exhibits accompanying this Registration Statement and is incorporated herein by
reference.

Item 22.  Undertakings.

   (a) The undersigned registrants hereby undertake:

      (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. Notwithstanding the foregoing, any
       increase or decrease in volume of securities offered (if the total
       dollar value of securities offered would not exceed that which was
       registered) and any deviation from the low or high end of the estimated
       maximum offering range may be reflected in the form of

                                     II-2



       prospectus filed with the Commission pursuant to Rule 424(b) if, in the
       aggregate, the changes in volume and price represent no more than 20
       percent change in the maximum aggregate offering price set forth in the
       "Calculation of Registration Fee" table in the effective registration
       statement; and

          (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;
       provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply
       if the registration statement is on Form S-3, Form S-8 or Form F-3, and
       the information required to be included in a post-effective amendment by
       those paragraphs is contained in periodic reports filed with or
       furnished to the Commission by the registrant pursuant to Section 13 or
       15(d) of the Exchange Act that are incorporated by reference in the
       registration statement.

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

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

   (b) The registrants hereby undertake that, for purposes of determining any
liability under the Securities Act of 1933, each filing of the registrants'
annual report pursuant to Section 13(a) or Section 15(d) of the Securities
Exchange Act of 1934 that is incorporated by reference in this registration
statement shall be deemed to be a new registration statement relating to the
securities offered herein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof;

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

   (d) The undersigned registrants hereby undertake to respond to requests for
information that are incorporated by reference into the prospectus pursuant to
Item 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.

   (e) The undersigned registrants hereby undertake 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.

                                     II-3



                                  SIGNATURES
