     This summary highlights information contained elsewhere in this prospectus
and the documents incorporated into it by reference. Because it is a summary, it
does not contain all of the information that you should consider before deciding
to exchange your old notes for new notes. You should read the entire prospectus
and the documents incorporated by reference carefully, including the section
entitled "Risk Factors" and the financial statements and related notes to those
financial statements incorporated by reference in this prospectus

"ours," "us" and the "Company" refer to Range Resources Corporation and its
subsidiaries, except where the context otherwise requires or as otherwise
indicated.

                                  OUR COMPANY

     We are an independent oil and natural gas company engaged in the
acquisition, development and exploration of oil and natural gas properties,
primarily in the Southwest, Gulf Coast, including the Gulf of Mexico, and
Appalachian regions of the United States. We seek to increase our reserves and
production primarily through development drilling, exploitation projects,
exploration and acquisitions. We also provide financing to smaller oil and
natural gas producers through our wholly-owned subsidiary, Independent Producer
Finance, or IPF, through the purchase of overriding royalty interests.

     We have a geographically diverse asset base. The Southwest division's
properties are located in the Permian Basin of West Texas, the East Texas Basin,
the Anadarko Basin of western Oklahoma and the Texas Panhandle. Our Gulf Coast
division operates properties onshore in Texas, Louisiana and Mississippi and
holds an interest in approximately 40 offshore platforms in the shallow waters
of the Gulf of Mexico. Through a 50%-owned joint venture, Great Lakes Energy
Partners L.L.C., or Great Lakes, we operate in the Appalachian and Michigan
Basins.

     In 2001, we set out to build a more technically-driven organization. We are
now pursuing a growth strategy that balances the exploitation of our inventory
of lower risk development drilling locations with higher potential exploration
projects and a complementary acquisition effort. Through this approach, we seek
to manage risk in every aspect of our business while generating attractive
returns.

     Our principal executive offices are located at 777 Main Street, Suite 800,
Fort Worth, Texas 76102. Our telephone number is (817) 870-2601.

                               THE EXCHANGE OFFER

     On July 21, 2003, we completed a private offering of the old notes. We
entered into a registration rights agreement with the initial purchasers in the
private offering in which we agreed, among other things, to deliver this
prospectus to you and to use our reasonable best efforts to consummate the
exchange offer within 210 days following the date of the original issuance of
the old notes. The following is a summary of the exchange offer.

Exchange Offer................   We are offering to exchange new notes for old
                                 notes.

Expiration date...............   The exchange offer will expire at 5:00 p.m. New
                                 York City time, on October 22, 2003, unless we
                                 decide to extend it. We do not currently intend
                                 to extend the exchange offer. The exchange
                                 offer must remain open for not less than thirty
                                 days (or longer if required by applicable law)
                                 after the date notice of the exchange offer is
                                 mailed to holders of the old notes.

Condition to the exchange
offer.........................   The registration rights agreement does not
                                 require us to accept old notes for exchange if
                                 the exchange offer or the making of any
                                 exchange by a holder of the old notes would
                                 violate any applicable law or interpretation of
                                 the staff of the Securities and Exchange
                                 Commission. The tender of a minimum aggregate
                                 principal amount of old notes is not a
                                 condition to the exchange offer.

                                 in book-entry form. The ATOP procedures require
                                 that the exchange agent receive, prior to the
                                 expiration date of the exchange offer, a
                                 computer-generated message known as an "agent's
                                 message" that is transmitted through ATOP and
                                 that DTC confirm that:

                                   - DTC has received instructions to exchange
                                     your notes; and

                                   - you agree to be bound by the terms of the
                                     letter of transmittal.

                                 otherwise transfer them under an exemption from
                                 the registration requirements of, or in a
                                 transaction not subject to, the Securities Act.

Tax consideration.............   We believe that the exchange of new notes for
                                 old notes should not be an exchange or
                                 otherwise a taxable event to a holder for
                                 United States federal income tax purposes.
                                 Please read "United States Federal Income Tax
                                 Considerations."

Exchange agent................   We have appointed Bank One, National
                                 Association as exchange agent for the exchange
                                 offer. You should direct questions, requests
                                 for assistance and requests for additional

                             TERMS OF THE NEW NOTES

     The new notes will be identical to the old notes except that the new notes
are registered under the Securities Act and will not have restrictions on
transfer, registration rights or provisions for additional interest. The new
notes will evidence the same debt as the old notes, and the same indenture will
govern the new notes and the old notes. When we use the term "notes," we mean
the new notes together with the old notes.

     The following summary contains basic information about the new notes and is
not intended to be complete. It does not contain all the information that is
important to you. For a more complete understanding of the new notes, please
refer to the section of this document entitled "Description of the New Notes."

Issuer........................   Range Resources Corporation.

                                 option, in whole or in part, at the redemption
                                 prices set forth under the heading "Description
                                 of the New Notes -- Optional Redemption," plus
                                 accrued and unpaid interest thereon to the
                                 applicable redemption date. In addition, prior
                                 to July 15, 2006, we may, at our option, on any
                                 one or more occasions, redeem up to 35% of the
                                 original aggregate principal amount of the
                                 notes at a redemption price equal to 107.375%
                                 of the principal amount thereof, plus accrued
                                 and unpaid interest, if any, to the redemption
                                 date, with all or a portion of the net proceeds
                                 of public sales of equity interests of the

                                 occurrence of such redemption. See "Description
                                 of the New Notes -- Optional Redemption."

                                        4


Change of control.............   Upon a "change of control," you as a holder of
                                 the notes will have the right to require us to
                                 make an offer to repurchase all or a portion of
                                 the notes at a purchase price of 101% of their
                                 aggregate principal amount, plus accrued and
                                 unpaid interest, if any, to the date of
                                 repurchase. Our credit agreement prohibits us
                                 from repurchasing any notes pursuant to a
                                 change of control offer prior to the repayment
                                 in full of the senior debt under our credit
                                 agreement. Therefore, if a change of control
                                 were to occur, there can be no assurance that
                                 we or the subsidiary guarantors will have the
                                 financial resources or be permitted under the
                                 terms of our or their indebtedness to
                                 repurchase the notes. If any "event of default"
                                 occurs, the trustee or holders of at least 25%
                                 in principal amount of the notes then
                                 outstanding may declare the principal of and
                                 the accrued and unpaid interest on such notes
                                 to be due and payable immediately. However,
                                 such repayment would be subject to the
                                 subordination provisions in our indenture. See
                                 "Description of the New Notes -- Subordination"
                                 and "-- Repurchase at the Option of
                                 Holders -- Change of control," and "-- Events
                                 of Default and Remedies."

Ranking.......................   The new notes will be general, unsecured
                                 obligations, will be subordinated in right of
                                 payment to our senior debt, which includes
                                 borrowings under our credit agreement and any
                                 other permitted indebtedness which does not
                                 expressly provide that it is on a parity with
                                 or subordinated in right of payment to the new
                                 notes. The new notes and the old notes will
                                 constitute a single class of securities under
                                 the indenture. See "Capitalization" and
                                 "Description of the New
                                 Notes -- Subordination."

Subsidiary guarantees.........   Our payment obligations under the new notes
                                 will be jointly, severally and unconditionally
                                 guaranteed on a senior subordinated basis by
                                 each of our restricted subsidiaries and any
                                 future restricted subsidiaries. The guarantees
                                 will be subordinated to senior debt of the
                                 subsidiary guarantors to the same extent and in
                                 the same manner as the new notes are
                                 subordinated to senior debt. See "Description
                                 of the New Notes -- Guarantees."

Certain covenants.............   The new notes will be issued pursuant to the
                                 same indenture as the old notes. This indenture
                                 contains certain covenants that will, among
                                 other things, limit the ability of us and our
                                 restricted subsidiaries to incur additional
                                 indebtedness and issue disqualified stock, pay
                                 dividends, make distributions, make
                                 investments, make certain other restricted
                                 payments, enter into certain transactions with
                                 affiliates, dispose of certain assets, incur
                                 liens securing indebtedness of any kind (other
                                 than permitted liens) and engage in mergers and
                                 consolidations. See "Description of the New
                                 Notes -- Certain Covenants."

Transfer Restrictions; Absence
of a Public Market for the New
Notes.........................   The new notes generally will be freely
                                 transferable, but will also be new securities
                                 for which there is no existing market. There
                                 can be no assurance as to the development or
                                 liquidity of any market for trading. We do not
                                 intend to apply for a listing of the new notes
                                 on any securities exchange or any automated
                                 dealer quotation system.

     For purposes of calculating the ratio of earnings to fixed charges:

     - "fixed charges" represent interest expense, amortization of debt costs
       and the portion of rental expense representing the interest factor, and

     - "earnings" represent the aggregate of income from continuing operations
       and fixed charges.

     For the years ended December 31, 1999 and 1998, earnings were inadequate to
cover fixed charges by $22.8 million and $229.6 million, respectively.

                                  RISK FACTORS

     You should carefully consider and evaluate all the information included or
incorporated by reference in this prospectus, including the risks described
below, before you decide to participate in the exchange offer. Our business,
financial condition and results of operations could be materially adversely
affected by any of these risks. The trading price of the new notes could
decline, and you may lose all or part of your investment. The risks described
below are not the only ones facing our company. Additional risks not presently
known to us or that we currently deem immaterial, individually or in the
aggregate, may also impair our business operations.

     This prospectus and the documents incorporated by reference also contain
forward-looking statements that involve risks and uncertainties, some of which
are described in the documents incorporated by reference in this prospectus. Our
actual results could differ materially from those anticipated in these
forward-looking statements as a result of various factors, including the risks
and uncertainties faced by us described below or incorporated by reference in
this prospectus.

RISKS RELATED TO OUR BUSINESS

  OIL AND NATURAL GAS PRICES ARE VOLATILE, AND AN EXTENDED DECLINE IN PRICES
  WOULD HURT OUR PROFITABILITY AND FINANCIAL CONDITION.

     The oil and natural gas industry is cyclical, and prices for oil and
natural gas are volatile. Historically, the industry has experienced severe
downturns characterized by oversupply and/or weak demand. For example, in 1998
and early 1999, oil and natural gas prices fell, which contributed to the
substantial losses we reported in those years. By early 2001, oil and natural
gas prices reached levels above their historical norm. Prices declined in the
second half of 2001 but have risen since mid-2002.

     Many factors affect oil and natural gas prices including general economic
conditions, consumer preferences, discretionary spending levels, interest rates
and the availability of capital to the industry. Decreases in oil and natural
gas prices from current levels could adversely affect our revenues, net income,
cash flow and proved reserves. Significant and prolonged price decreases could
have a material adverse effect on our operations and limit our ability to fund
capital expenditures. Without the ability to fund capital expenditures, we may
be unable to replace production.

  HEDGING TRANSACTIONS MAY LIMIT OUR POTENTIAL GAINS AND INVOLVE OTHER RISKS.

     To manage our exposure to price risk, we enter into hedging arrangements
from time to time with respect to a portion of our future production. The goal
of these hedges is to limit volatility and increase the predictability of cash
flow. These transactions may limit our potential gains if oil and natural gas
prices were to rise over the price established by the hedge. For example, at
December 31, 2002, we were party to hedging arrangements covering 64.6 Bcf and
1.6 million barrels of oil. The hedges' fair value was a pre-tax loss of $32.9
million. Due to additional hedging activity and rising prices, the fair value of
these hedges on June 30, 2003 was a pre-tax loss of $82.0 million. If oil and
natural gas prices continue to rise, we could be subject to margin calls.

     In addition, hedging transactions may expose us to the risk of financial
loss in certain circumstances, including instances in which:

     - our production is less than expected;

     - the counterparties to our futures contracts fail to perform under the
       contracts; or

     - a sudden, unexpected event materially impacts oil or natural gas prices.

  INFORMATION CONCERNING OUR RESERVES AND FUTURE NET RESERVE ESTIMATES IS
  UNCERTAIN.

     There are numerous uncertainties inherent in estimating quantities of
proved oil and natural gas reserves and their values, including many factors
beyond our control. Estimates of proved undeveloped

                                        7


reserves, which comprise a significant portion of our reserves, are by their
nature uncertain. The reserve data included or incorporated by reference in this
prospectus is estimated. Although we believe these estimates are reasonable,
actual production, revenues and reserve expenditures will likely vary from
estimates, and these variances could be material.

     The accuracy of any reserves estimate is a function of the quality of
available data, engineering and geological interpretation and judgment,
assumptions used regarding quantities of oil and natural gas in place, recovery
rates and future prices for oil and natural gas. Actual prices, production,
development expenditures, operating expenses and quantities of recoverable oil
and natural gas reserves will vary from those assumed in our estimates, and such
variances may be material. Any variance in the assumptions could materially
affect the estimated quantity value of the reserves.

     For example, in 1997 and 1998, we consummated several large acquisitions
which proved extremely disappointing. Production from the acquired properties
fell more rapidly than anticipated and further development results were far
below the results we had originally projected. The poor production performance
of these properties resulted in material downward reserve revisions.

  IF OIL AND NATURAL GAS PRICES DECREASE OR EXPLORATION EFFORTS ARE
  UNSUCCESSFUL, WE MAY BE REQUIRED TO TAKE ADDITIONAL WRITEDOWNS OF OUR OIL AND
  NATURAL GAS PROPERTIES.

     In the past, we have been required to write down the carrying value of our
oil and natural gas properties, and there is a risk that we will be required to
take additional writedowns in the future. This could occur when oil and natural
gas prices are low or if we have substantial downward adjustments to our
estimated proved reserves, increases in our estimates of development costs or
deterioration in our exploration results.

     Accounting rules require that the carrying value of oil and natural gas
properties be periodically reviewed for possible impairment. "Impairment" is
recognized when the book value of a proven property is greater than the expected
undiscounted future cash flows from that property and on acreage when the
assessment of fair value is less than the book value. We may be required to
write down the carrying value of a property based on oil and natural gas prices
at the time of the impairment review, as well as a continuing evaluation of
development results, production data, economics and other factors. While an
impairment charge which reflects our long-term ability to recover on a prior
investment does not impact cash or cash flow from operating activities, it
reduces our earnings and increases our leverage ratios.

     For example, based primarily on the poor performance of certain properties
acquired in 1997 and 1998 and significantly lower oil and natural gas prices, we
recorded impairments of $215.0 million in 1998 and $29.9 million in 1999. At
year-end 2001, we also recorded an impairment of $31.1 million due to year-end
prices.

  OUR BUSINESS IS SUBJECT TO OPERATING HAZARDS AND ENVIRONMENTAL REGULATIONS
  THAT COULD RESULT IN SUBSTANTIAL LOSSES OR LIABILITIES.

     Oil and natural gas operations are subject to many risks, including well
blowouts, craterings, explosions, uncontrollable flows of oil, natural gas or
well fluids, fires, formations with abnormal pressures, pipeline ruptures or
spills, pollution, releases of toxic gas and other environmental hazards and
risks. If any of these hazards occur, we could sustain substantial losses as a
result of:

     - injury or loss of life;

     - severe damage to or destruction of property, natural resources and
       equipment;

     - pollution or other environmental damage;

     - clean-up responsibilities;

     - regulatory investigations and penalties; and/or

     - suspension of operations.
                                        8


     Our current and former operations are subject to numerous and increasingly
strict federal, state and local laws, regulations and enforcement policies
relating to the environment. We may incur significant costs and liabilities in
complying with existing or future environmental laws, regulations and
enforcement policies and may incur costs arising out of property damage or
injuries to employees and other persons. These costs may result from our current
and former operations and even may be caused by previous owners of property we
own or lease. Any past, present or future failure by us to completely comply
with environmental laws, regulations and enforcement policies could cause us to
incur substantial fines, sanctions or liabilities for cleanup costs or other
damages. Incurrence of those costs or damages could reduce or eliminate funds
available for exploration, development or acquisitions or cause us to incur
losses.

     We maintain insurance against some, but not all, of these potential risks
and losses. We may elect not to obtain insurance if we believe that the cost of
available insurance is excessive relative to the risks presented. In addition,
pollution and environmental risks generally are not fully insurable. If a
significant accident or other event occurs that is not fully covered by
insurance, it could have a material adverse affect on our financial condition
and results of operations.

  WE ARE SUBJECT TO FINANCING AND INTEREST RATE EXPOSURE RISKS.

     Our business and operating results can be harmed by factors such as the
availability and cost of capital, increases in interest rates or a reduction in
credit rating. These changes could cause our cost of doing business to increase,
limit our ability to pursue opportunities and place us at a competitive
disadvantage. For example, at June 30, 2003, a portion of our borrowings, held
through our Great Lakes joint venture, were subject to interest rate swap
agreements, which were above market, and therefore, increased our interest
expense.

  OUR INDUSTRY IS HIGHLY COMPETITIVE.

     We face competition in every aspect of our business, including, but not
limited to, acquiring reserves and leases, obtaining goods, services and
employees needed to operate and manage our business, and marketing oil and
natural gas. Competitors include multinational oil companies, independent
production companies and individual producers and operators. Many of our
competitors have greater financial and other resources than we do.

  THE OIL AND NATURAL GAS INDUSTRY IS SUBJECT TO EXTENSIVE REGULATION.

     The oil and natural gas industry is subject to various types of regulations
in the United States by local, state and federal agencies. Legislation affecting
the industry is under constant review for amendment or expansion, frequently
increasing our regulatory burden. Numerous departments and agencies, both state
and federal, are authorized by statute to issue rules and regulations binding on
participants in the oil and natural gas industry. Compliance with such rules and
regulations often increases our cost of doing business and, in turn, decreases
our profitability. Generally these burdens do not appear to affect us to any
greater or lesser extent than other companies in the oil and natural gas
industry with similar types and quantities of properties in the same areas of
the country.

  ACQUISITIONS BY US ARE SUBJECT TO THE RISKS AND UNCERTAINTIES OF EVALUATING
  RECOVERABLE RESERVES AND POTENTIAL LIABILITIES.

     We could be subject to significant liabilities related to acquisitions by
us. It generally is not feasible to review in detail every individual property
included in an acquisition. Ordinarily, a review is focused on higher valued
properties. However, even a detailed review of all properties and records may
not reveal existing or potential problems, nor will it permit us to become
sufficiently familiar with the properties to assess fully their deficiencies and
capabilities. We do not always inspect every well we acquire, and environmental
problems, such as groundwater contamination, are not necessarily observable even
when an inspection is performed.

                                        9


     For example, in 1997 and 1998, we consummated a series of acquisitions
which proved unsuccessful. Since the date of these acquisitions, the production
results relating to these acquired properties have indicated that the potential
of the acquired properties was far below the level that our engineering and
geological review, as well as a review by one of our independent petroleum
engineering firms, had initially suggested.

  OUR SUCCESS DEPENDS ON KEY MEMBERS OF OUR MANAGEMENT AND OUR ABILITY TO
  ATTRACT AND RETAIN EXPERIENCED EXPLORATIONISTS AND OTHER PROFESSIONAL
  PERSONNEL.

     Our success is highly dependent on our senior management personnel, none of
which are currently subject to an employment contract. The loss of one or more
of these individuals could have a material adverse effect on our business.
Furthermore, competition for experienced explorationists and engineers is
intense. If we cannot retain our current personnel or attract additional
experienced personnel, our ability to compete could be adversely affected.

  OUR FUTURE SUCCESS DEPENDS ON OUR ABILITY TO REPLACE RESERVES THAT WE PRODUCE.

     Because the rate of production from oil and natural gas properties
generally declines as reserves are depleted, our future success depends upon our
ability to find or acquire additional oil and natural gas reserves that are
economically recoverable. Except to the extent that we acquire additional
properties containing proved reserves, conduct successful exploration and
development activities or, through engineering studies, identify additional
behind-pipe zones or secondary recovery reserves, our proved reserves will
decline materially as reserves are produced. Future oil and natural gas
production is, therefore, highly dependent upon our level of success in
acquiring or finding additional reserves that are economically recoverable. We
cannot assure you that we will be able to find and develop or acquire additional
reserves at an acceptable cost.

  A PORTION OF OUR BUSINESS IS SUBJECT TO SPECIAL RISKS RELATED TO OFFSHORE
  OPERATIONS GENERALLY AND IN THE GULF OF MEXICO SPECIFICALLY.

     Offshore operations are subject to a variety of operating risks specific to
the marine environment, such as capsizing, collisions and 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 that could reduce or eliminate the funds available
for exploration, development or leasehold acquisitions, or result in loss of
equipment and properties.

     Production of reserves from reservoirs in the Gulf of Mexico generally
declines more rapidly than from reservoirs in many other producing regions of
the world. This results in recovery of a relatively higher percentage of
reserves from properties in the Gulf of Mexico during the initial few years of
production. As a result, reserve replacement needs from new prospects are
greater and require us to incur significant capital expenditure to replace
production.

  NEW TECHNOLOGIES MAY CAUSE OUR CURRENT EXPLORATION AND DRILLING METHODS TO
  BECOME OBSOLETE.

     The oil and natural gas industry is subject to rapid and significant
advancements in technology, including the introduction of new products and
services using new technologies. As competitors use or develop new technologies,
we may be placed at a competitive disadvantage, and competitive pressures may
force us to implement new technologies at a substantial cost. In addition,
competitors may have greater financial, technical and personnel resources that
allow them to enjoy technological advantages and may in the future allow them to
implement new technologies before we can. We cannot be certain that we will be
able to implement technologies on a timely basis or at a cost that is acceptable
to us. One or more of the technologies that we currently use or that we may
implement in the future may become obsolete, and we may be adversely affected.

                                        10


  OUR BUSINESS DEPENDS ON OIL AND NATURAL GAS TRANSPORTATION FACILITIES, SOME OF
  WHICH ARE OWNED BY OTHERS.

     The marketability of our oil and natural gas production depends in part on
the availability, proximity and capacity of pipeline systems owned by third
parties. The unavailability of or lack of available capacity on these systems
and facilities could result in the shut-in of producing wells or the delay or
discontinuance of development plans for properties. Although we have some
contractual control over the transportation of our product, material changes in
these business relationships could materially affect our operations. Federal and
state regulation of oil and natural gas production and transportation, tax and
energy policies, changes in supply and demand, pipeline pressures, damage to or
destruction of pipelines and general economic conditions could adversely affect
our ability to produce, gather and transport oil and natural gas.

RISKS RELATED TO THE EXCHANGE OFFER AND THE NEW NOTES

  IF YOU DO NOT PROPERLY TENDER YOUR OLD NOTES, YOU WILL CONTINUE TO HOLD
  UNREGISTERED OLD NOTES AND YOUR ABILITY TO TRANSFER OLD NOTES WILL BE
  ADVERSELY AFFECTED.

     We will only issue new notes in exchange for old notes that you timely and
properly tender. Therefore, you should allow sufficient time to ensure timely
delivery of the old notes and carefully follow the instructions on how to tender
your old notes. Neither we nor the exchange agent are required to tell you of
any defects or irregularities with respect to your tender of the old notes.

     If you do not exchange your old notes for new notes pursuant to the
exchange offer, the old notes you hold will continue to be subject to the
existing transfer restrictions. In general, you may not offer or sell the old
notes except under an exemption from, or in a transaction not subject to, the
Securities Act and applicable state securities laws. We do not plan to register
old notes under the Securities Act. Further, if you continue to hold any old
notes after the exchange offer is consummated, you may not be able to sell the
old notes because there will be fewer old notes outstanding.

  OUR SIGNIFICANT INDEBTEDNESS COULD LIMIT OUR ABILITY TO SUCCESSFULLY OPERATE
  OUR BUSINESS AND PREVENT US FROM FULFILLING OUR OBLIGATIONS UNDER THE NEW
  NOTES.

     We are substantially leveraged, and our exploration and development program
will require substantial capital resources, estimated to range from $100 to $130
million per year over the next three years, and the operation of our existing
operations will also require ongoing capital expenditures.

     The degree to which we are leveraged could have other important
consequences to you, including the following:

     - we must dedicate a substantial portion of our cash flows from operations
       to the payment of our indebtedness, reducing the funds available to pay
       principal and interest on the new notes and for our operations;

     - a portion of our borrowings are at variable rates of interest, making us
       vulnerable to increases in interest rates;

     - we may be more highly leveraged than some of our competitors, which could
       place us at a competitive disadvantage;

     - our degree of leverage may make us more vulnerable to a downturn in our
       business or the economy generally;

     - the terms of our existing credit arrangements and the indenture governing
       the new notes contain numerous financial and other restrictive covenants;

     - our debt level could limit our flexibility in planning for, or reacting
       to, changes in our business and the industry in which we operate; and

     - we may have difficulties borrowing money in the future.

                                        11


  DESPITE OUR CURRENT LEVELS OF INDEBTEDNESS WE STILL MAY BE ABLE TO INCUR
  SUBSTANTIALLY MORE DEBT. THIS COULD FURTHER INCREASE THE RISKS DESCRIBED
  ABOVE.

     We may be able to incur substantial additional indebtedness in the future.
The terms of the indenture relating to the new notes do not prohibit us from
doing so. As of June 30, 2003, our senior credit facility would permit
additional borrowings of $59.4 million and all of those borrowings would be
senior to the new notes. If new debt is added to our current debt levels, the
related risks that we now face could intensify. See "Capitalization."

  ANY FAILURE TO MEET OUR DEBT OBLIGATIONS COULD HARM OUR BUSINESS, FINANCIAL
  CONDITION AND RESULT OF OPERATIONS.

     If our cash flow and capital resources are insufficient to fund our debt
obligations, we may be forced to sell assets, seek additional equity or debt
capital or restructure our debt. In addition, any failure to make scheduled
payments of interest and principal on our outstanding indebtedness would likely
result in a reduction of our credit rating, which could harm our ability to
incur additional indebtedness on acceptable terms. Our cash flow and capital
resources may be insufficient for payment of interest on and principal of our
debt in the future, including payments on the new notes, and any such
alternative measures may be unsuccessful or may not permit us to meet scheduled
debt service obligations, which could cause us to default on our obligations and
impair our liquidity.

  YOUR RIGHT TO RECEIVE PAYMENTS ON THE NEW NOTES IS SUBORDINATED TO THE RIGHTS
  OF OUR SENIOR INDEBTEDNESS AND EFFECTIVELY SUBORDINATED TO THE RIGHTS OF
  EXISTING AND FUTURE CREDITORS OF ANY SUBSIDIARIES THAT ARE NOT GUARANTORS ON
  THE NEW NOTES.

     Holders of our senior indebtedness will have claims that are prior to your
claims as holders of the new notes. In the event of any distribution of our
assets in any foreclosure, dissolution, winding-up, liquidation, reorganization,
or other bankruptcy proceeding, holders of senior indebtedness will have prior
claim to all of our assets. Holders of the new notes will participate ratably
with all holders of our senior subordinated indebtedness that is deemed to be of
the same class as the new notes, based upon the respective amounts owed to each
holder or creditor, in our remaining assets. In any of the foregoing events, we
cannot assure you that there will be sufficient assets to pay amounts due on the
new notes. As a result, holders of new notes may receive less, ratably, than
holders of senior indebtedness.

     As of June 30, 2003, we had total senior indebtedness of approximately
$184.1 million, including our 50% portion of indebtedness owed by our Great
Lakes joint venture under its credit facility. We may incur additional
indebtedness in the future under the terms of the indenture.

     We conduct substantially all of our operations through our subsidiaries and
some of our subsidiaries do not guarantee the new notes. In addition, we may be
able to designate one or more subsidiaries in the future as unrestricted
subsidiaries. As a result, holders of the new notes will be effectively
subordinated to the indebtedness and other liabilities of any such subsidiaries,
including trade creditors. Therefore, in the event of the insolvency or
liquidation of an unrestricted subsidiary, following payment by such subsidiary
of its liabilities, such subsidiary may not have sufficient remaining assets to
make payments to us as a shareholder or otherwise. In the event of a default by
any such subsidiary under any credit arrangement or other indebtedness, its
creditors could accelerate such debt, prior to such subsidiary distributing
amounts to us that we could have used to make payments on the new notes.

  WE MAY NOT BE ABLE TO REPURCHASE THE NEW NOTES.

     You may require us to repurchase all or a portion of your new notes on
certain dates or in the event of a change in control. We may not have enough
funds to pay the repurchase price on a purchase date. Our existing and any
future credit agreements or other debt agreements to which we become a party may
provide that our obligation to repurchase the new notes would be an event of
default under such agreement. As a result, we may be restricted or prohibited
from repurchasing the new notes. If we are prohibited from repurchasing the new
notes, we could seek the consent of our then-existing lenders to
                                        12


repurchase the new notes or we could attempt to refinance the borrowings that
contain such prohibition. If we are unable to obtain a consent or refinance the
debt, we could not repurchase the new notes. Our failure to repurchase tendered
new notes would constitute a default under the indenture and might constitute a
default under the terms of other indebtedness that we incur.

     The term "change in control" is limited to certain specified transactions
and may not include other events that might adversely affect our financial
condition. Our obligation to repurchase the new notes upon a change in control
would not necessarily afford holders of new notes protection in the event of a
highly leveraged transaction, reorganization, merger or similar transaction
involving us.

  THE NEW NOTES MAY NOT BE RATED OR MAY RECEIVE A LOWER RATING THAN ANTICIPATED.

     We believe it is unlikely that the new notes will be rated. However, if one
or more rating agencies rates the new notes and assigns the new notes a rating
lower than the rating expected by investors, or reduces their rating in the
future, the market price of the new notes would be harmed.

  YOU MAY FIND IT DIFFICULT TO SELL YOUR NEW NOTES.

     You may find it difficult to sell your new notes because an active trading
market for the new notes may not develop. There is no existing trading market
for the new notes issued in this exchange offer. We do not know the extent to
which investor interest will lead to the development of a trading market or how
liquid that market might be. As a result, the market price of the new notes
could be adversely affected.

                                        13


                                 EXCHANGE OFFER

     We sold the old notes on July 21, 2003 pursuant to a purchase agreement
dated July 16, 2003, by and among us and the initial purchasers named therein.
The old notes were subsequently offered by the initial purchasers to qualified
institutional buyers pursuant to Rule 144A under the Securities Act and outside
the United States to persons other than U.S. persons in reliance on Regulation S
under the Securities Act.

PURPOSE AND EFFECT OF THE EXCHANGE OFFER

     In connection with the issuance of the old notes, we entered into a
registration rights agreement under which we agreed to:

     - within 90 days after the issue date of the old notes, file a registration
       statement with the Securities and Exchange Commission with respect to a
       registered offer to exchange the old notes for new notes of ours having
       terms substantially identical in all material respects to the old notes
       except with respect to transfer restrictions;

     - use our 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;

     - use our reasonable best efforts to consummate the exchange offer within
       210 days after the issue date of the old notes;

     - 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; and

     - to file a shelf registration for the resale of the old notes if we cannot
       consummate the exchange offer within the time period listed above and
       certain other circumstances described in this prospectus.

     For each old note tendered to us pursuant to the exchange offer, we will
issue to the holder of such old note a new note having a principal amount equal
to that of the surrendered old note. Interest on each new note will accrue from
the last date upon which we paid interest on the old note, unless no interest
has been paid on the old note, in which case, interest shall be paid from the
original issuance date of the old note.

     Under existing interpretations of the staff of the Securities and Exchange
Commission issued to third parties, 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
our affiliate, as such terms are interpreted by the Securities and Exchange
Commission; 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 staff of the Securities and Exchange Commission
has taken the position in interpretations issued to third parties that
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 the
registration statement covering the new notes. 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 the registration
statement in connection with the resale of the 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).

                                        14


     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
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 our "affiliate," 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 Securities and Exchange Commission do not permit us to effect an
       exchange offer;

     - for any other reason the exchange offer is not consummated within 210
       days after the issue date of the old notes;

     - any holder of old notes, other than the initial purchasers, notifies us
       prior to the 20th business day following the consummation of the exchange
       offer it is prohibited by law or the applicable interpretations of the
       staff of the Securities and Exchange Commission from participating in the
       exchange offer;

     - in the case of any holder of old notes who 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 and federal securities
       laws (other than due solely to the status of such holders as an affiliate
       of ours within the meaning of the Securities Act); or

     - an initial purchaser so requests with respect to old notes or private
       exchange notes that have, or that are reasonably likely to be determined
       to have, the status of unsold allotments in an initial distribution;

then we will, at our cost, use our reasonable best efforts to file and use our
reasonable best efforts to have declared effective a shelf registration
statement covering resales of the old notes on or prior to the later of 180
calendar days after the issue date of the old notes or 90 days after the shelf
registration statement is required to be filed with the Securities and Exchange
Commission.

     We will use our reasonable best efforts to keep the shelf registration
statement effective until two years after the issue date of the old notes,
subject to certain exceptions. We will, if we file a shelf registration
statement, 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 which are applicable to such
holder (including certain indemnification obligations).

     The registration rights agreement obligates us to pay additional cash
interest on the principal amount of the applicable old notes and new notes (in
addition to the stated interest on the old notes and the new notes) upon the
occurrence of any of the following events:

     - if the registration statement of which this prospectus forms a part is
       not declared effective by the Securities and Exchange Commission on or
       prior to the 180th day after the issue date of the old notes (the
       "effectiveness deadline");

     - if the exchange offer is not consummated on or prior to the earlier of
       the 30th business day following the effectiveness deadline or the 210th
       day following the issue date of the old notes;

                                        15


     - if obligated to file the shelf registration statement, it is not declared
       effective by the later of 180 calendar days after the issue date of the
       old notes or 90 days after the shelf registration statement is required
       to be filed with the Securities and Exchange Commission; or

     - after the shelf registration statement is declared effective it ceases to
       be effective or usable (subject to some exceptions);

from and including the date on which any registration default shall occur to,
but excluding, the earlier of (1) the date on which all registration defaults
have been cured or (2) the date on which all the old notes and the new notes
otherwise become freely transferable by holders other than our affiliates
without further registration under the Securities Act. The additional cash
interest will accrue at a rate of .25% per annum during the 90 day period
immediately following the occurrence of a registration default and shall
increase by an additional .25% per annum with respect to each subsequent 90 day
period, up to a maximum amount of additional interest of .50% per annum.

RESALE OF NEW NOTES

     Based on no action letters of the staff of the Securities and Exchange
Commission issued to third parties, we believe that new notes may be offered for
resale, resold and otherwise transferred by you without further compliance with
the registration and prospectus delivery provisions of the Securities Act if:

     - you are not our "affiliate" within the meaning of Rule 405 under the
       Securities Act;

     - such new notes are acquired in the ordinary course of your business; and

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

     The staff of the Securities and Exchange Commission, however, has not
considered the exchange offer for the new notes in the context of a no action
letter, and the staff of the Securities and Exchange Commission may not make a
similar determination as in the no action letters issued to these third parties.

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

     - you cannot rely on such interpretations by the Securities and Exchange
       Commission staff issued to third parties; and

     - you must comply with the registration and prospectus delivery
       requirements of the Securities Act in connection with a secondary resale
       transaction.

     Unless an exemption from registration is otherwise available, any security
holder intending to distribute new notes should be covered by an effective
registration statement under the Securities Act. This registration statement
should contain the selling security holder's information required by Item 507 of
Regulation S-K under the Securities Act. This prospectus may be used for an
offer to resell, resale or other retransfer of new notes only as specifically
described in this prospectus. Only broker-dealers that acquired the old 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.

TERMS OF THE EXCHANGE OFFER

     Subject to the terms and conditions described in this prospectus and in the
letter of transmittal, we will accept for exchange any old notes properly
tendered and not withdrawn prior to the expiration date. We will issue new notes
in principal amount equal to the principal amount of old notes surrendered under
the exchange offer. Old notes may be tendered only for new notes and only in
integral multiples of $1,000.

                                        16


     The exchange offer is not conditioned upon any minimum aggregate principal
amount of old notes being tendered for exchange.

     As of the date of this prospectus, $100,000,000 aggregate principal amount
of the old notes is outstanding. This prospectus and the letter of transmittal
are being sent to all registered holders of old notes. There will be no fixed
record date for determining registered holders of old notes entitled to
participate in the exchange offer.

     We intend to conduct the exchange offer in accordance with the provisions
of the registration rights agreement, the applicable requirements of the
Securities Act and the Securities Exchange Act of 1934 and the rules and
regulations of the Securities and Exchange Commission. Old notes that the
holders thereof do not tender for exchange in the exchange offer will remain
outstanding and continue to accrue interest. These old notes will be entitled to
the rights and benefits such holders have under the indenture relating to the
old notes and the registration rights agreement.

     We will be deemed to have accepted for exchange properly tendered old notes
when we have given oral or written notice of the acceptance to the exchange
agent and complied with the applicable provisions of the registration rights
agreement. The exchange agent will act as agent for the tendering holders for
the purposes of receiving the new notes from us.

     If you tender old notes in the exchange offer, you will not be required to
pay brokerage commissions or fees or, subject to the letter of transmittal,
transfer taxes with respect to the exchange of old notes. We will pay all
charges and expenses, other than certain applicable taxes described below, in
connection with the exchange offer. It is important that you read the section
labeled "-- Fees and Expenses" for more details regarding fees and expenses
incurred in the exchange offer.

     We will return any old notes that we do not accept for exchange for any
reason without expense to their tendering holder promptly after the expiration
or termination of 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 such new
notes. See "Plan of Distribution."

EXPIRATION DATE

     The exchange offer will expire at 5:00 p.m., New York City time, on October
22, 2003 unless, in our sole discretion, we extend it.

EXTENSIONS, DELAYS IN ACCEPTANCE, TERMINATION OR AMENDMENT

     We expressly reserve the right, at any time or various times, to extend the
period of time during which the exchange offer is open. We may delay acceptance
of any old notes by giving oral or written notice of such extension to their
holders if the exchange offer is so extended. During any such extensions, all
old notes previously tendered will remain subject to the exchange offer, and we
may accept them for exchange upon the expiration of the extended exchange offer.

     In order to extend the exchange offer, we will notify the exchange agent
orally or in writing of any extension. We will notify the registered holders of
old notes of the extension no later than 9:00 a.m., New York City time, on the
business day after the previously scheduled expiration date.

     If any of the conditions described below under "-- Conditions to the
Exchange Offer" have not been satisfied, we reserve the right, in our sole
discretion

     - to delay accepting for exchange any old notes,

     - to extend the exchange offer, or

     - to terminate the exchange offer,

                                        17


by giving oral or written notice of such delay, extension or termination to the
exchange agent. However, we may not delay acceptance for exchange of any old
notes after the expiration of the exchange offer. Subject to the terms of the
registration rights agreement, we also reserve the right to amend the terms of
the exchange offer in any manner.

     Any such delay in acceptance, extension, termination or amendment will be
followed promptly by oral or written notice thereof to the registered holders of
old notes. If we amend the exchange offer in a manner that we determine to
constitute a material change, we will promptly disclose such amendment by means
of a prospectus supplement. The supplement will be distributed to the registered
holders of the old notes. Depending upon the significance of the amendment and
the manner of disclosure to the registered holders, we will extend the exchange
offer if the exchange offer would otherwise expire during such period.

CONDITIONS TO THE EXCHANGE OFFER

     We will not be required to accept for exchange, or exchange any new notes
for, any old notes if 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 Securities and Exchange Commission.
Similarly, we may terminate the exchange offer as provided in this prospectus
before accepting old notes for exchange in the event of such a potential
violation.

     In addition, 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
"-- Purpose and Effect of the Exchange Offer," "-- Procedures for Tendering" and
"Plan of Distribution" and such other representations as may be reasonably
necessary under applicable Securities and Exchange Commission rules, regulations
or staff interpretations to allow us to use an appropriate form to register the
new notes under the Securities Act.

     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 to the exchange offer specified
above. 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.

     These conditions are for our sole benefit, and we may assert them or waive
them in whole or in part at any time prior to or on the expiration of the offer
in our sole discretion. If we fail at any time to exercise any of these rights,
this failure will not mean that we have waived our rights. Each such right will
be deemed an ongoing right that we may assert at any time prior to or on the
expiration of the offer.

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

PROCEDURES FOR TENDERING

  HOW TO TENDER GENERALLY

     To participate in the exchange offer, you must properly tender your old
notes to the exchange agent as described below. We will only issue new notes in
exchange for old notes that you timely and properly tender. Therefore, you
should allow sufficient time to ensure timely delivery of the old notes, and you
should follow carefully the instructions on how to tender your old notes. It is
your responsibility to properly tender your old notes. We have the right to
waive any defects. However, we are not required to waive defects, and neither we
nor the exchange agent is required to notify you of defects in your tender.

     If you have any questions or need help in exchanging your old notes, please
call the exchange agent whose address and phone number are described in the
letter of transmittal.

     All of the old notes were issued in book-entry form, and all of the old
notes are currently represented by a global certificate held by Cede & Co. for
the account of DTC. We have confirmed with DTC that the old notes may be
tendered using ATOP. The exchange agent will establish an account with DTC for
                                        18


purposes of the exchange offer promptly after the commencement of the exchange
offer, and DTC participants may electronically transmit their acceptance of the
exchange offer by causing DTC to transfer their old notes to the exchange agent
using the ATOP procedures. In connection with the transfer, DTC will send an
"agent's message" to the exchange agent. The agent's message will state that DTC
has received instructions from the participant to tender old notes and that the
participant agrees to be bound by the terms of the letter of transmittal.

     By using the ATOP procedures to exchange old notes, you will not be
required to deliver a letter of transmittal to the exchange agent. However, you
will be bound by its terms just as if you had signed it.

     There is no procedure for guaranteed late delivery of the old notes.

  DETERMINATIONS UNDER THE EXCHANGE OFFER

     We will determine in our sole discretion all questions as to the validity,
form, eligibility, time of receipt, acceptance of tendered old notes and
withdrawal of tendered old notes. Our determinations will be final and binding.
We reserve the absolute right to reject any old notes not properly tendered or
any old notes our acceptance of which would, in the opinion of our counsel, be
unlawful. We also reserve the rights 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, all
defects or irregularities in connection with tenders of old notes must be cured
within such time as we shall determine. Although we intend to notify holders of
defects or irregularities with respect to tenders of old notes, neither we, the
exchange agent nor any other person will incur any liability for failure to give
such notification. Tenders of old notes will not be deemed made until such
defects or irregularities have been cured or waived. Any old notes received by
the exchange agent that are not properly tendered and as to which the defects or
irregularities have not been cured or waived will be returned to the tendering
holder as soon as practicable following the expiration date.

  WHEN WE WILL ISSUE NEW NOTES

     In all cases, we will issue new notes for old notes that we have accepted
for exchange under the exchange offer only after the exchange agent timely
receives:

     - a book-entry confirmation of such old notes into the exchange agent's
       account at DTC; and

     - a properly transmitted agent's message.

  RETURN OF OLD NOTES NOT ACCEPTED OR EXCHANGED

     If we do not accept any tendered old notes for exchange or if old notes are
submitted for a greater principal amount than the holder desires to exchange,
the unaccepted or non-exchanged old notes will be returned without expense to
their tendering holder. Such non-exchanged old notes will be credited to an
account maintained with DTC. These actions will occur promptly after the
expiration or termination of the exchange offer.

  YOUR REPRESENTATIONS TO US

     By 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 within the meaning of
       the Securities Act;

     - 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;

                                        19


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

     - you are not our "affiliate," as defined in Rule 405 of the Securities Act
       or if you are our "affiliate" that you will comply with the registration
       and prospectus delivery requirements of the Securities Act to the extent
       applicable; and

     - you have full power and authority to transfer the old notes in exchange
       for the new notes and we will acquire good and unencumbered title thereto
       free and clear of any liens, restrictions, charges or encumbrances and
       not subject to any adverse claims.

WITHDRAWAL OF TENDERS

     Except as otherwise provided in this prospectus, you may withdraw your
tender at any time prior to the expiration date. For a withdrawal to be
effective you must comply with the appropriate ATOP procedures. Any notice of
withdrawal must specify the name and number of the account at DTC to be credited
with withdrawn old notes and otherwise comply with the ATOP procedures.

     We will determine all questions as to the validity, form, eligibility and
time of receipt of notice of withdrawal. 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.

     Any old notes that have been tendered for exchange but that are not
exchanged for any reason will be credited to an account maintained with DTC for
the old notes. This crediting will take place as soon as practicable after
withdrawal, rejection of tender or termination of the exchange offer. You may
retender properly withdrawn old notes by following the procedures described
under "-- Procedures for Tendering" above at any time on or prior to the
expiration date.

FEES AND EXPENSES

     We will bear the expenses of soliciting tenders. The principal solicitation
is being made by mail; however, we may make additional solicitation by
telegraph, telephone or in person by our officers and regular employees and
those of our affiliates.

     We have not retained any dealer-manager in connection with the exchange
offer and will not make any payments to broker-dealers or others soliciting
acceptances of the exchange offer. We will, however, pay the exchange agent
reasonable and customary fees for its services and reimburse it for its related
reasonable out-of-pocket expenses.

     We will pay the cash expenses to be incurred in connection with the
exchange offer. They include:

     - Securities and Exchange Commission registration fees;

     - fees and expenses of the exchange agent and trustee;

     - accounting and legal fees and printing costs; and

     - related fees and expenses.

TRANSFER TAXES

     We will pay all transfer taxes, if any, applicable to the exchange of old
notes under the exchange offer. The tendering holder, however, will be required
to pay any transfer taxes, whether imposed on the registered holder or any other
person, if a transfer tax is imposed for any reason other than the exchange of
old notes under the exchange offer.

                                        20


CONSEQUENCES OF FAILURE TO EXCHANGE

     If you do not exchange new notes for your old notes under the exchange
offer, you will remain subject to the existing restrictions on transfer of the
old notes. In general, you may not offer or sell the old notes unless they are
registered under the Securities Act or unless the offer or sale is exempt from
the 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.

ACCOUNTING TREATMENT

     We will record the new notes in our accounting records at the same carrying
value as the old notes. This carrying value is the aggregate principal amount of
the old notes, as reflected in our accounting records on the date of exchange.
Accordingly, we will not recognize any gain or loss for accounting purposes in
connection with the exchange offer. The expenses of the exchange offer will be
amortized over the term of the new notes.

OTHER

     Participation in the exchange offer is voluntary, and you should carefully
consider whether to accept. You are urged 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. 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 of any untendered old notes.

     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."

                                USE OF PROCEEDS

     The exchange offer is intended to satisfy our obligations under the
registration rights agreement. We will not receive any cash proceeds from the
issuance of the new notes in the exchange offer. In consideration for issuing
the new notes as contemplated by this prospectus, we will receive old notes in a
like principal amount. The form and terms of the new notes are identical in all
respects to the form and terms of the old notes, except the new notes are
registered under the Securities Act and will not have restrictions on transfer,
registration rights or provisions for additional cash interest. Old notes
surrendered in exchange for the new notes will be retired and cancelled and will
not be reissued. Accordingly, the issuance of the new notes will not result in
any increase in our outstanding indebtedness.

                                        21


                                 CAPITALIZATION

     The following table sets forth our capitalization as of June 30, 2003 on an
actual basis and as adjusted to give effect to the offering of the old notes and

       aggregate principal amount of 8 3/4% senior subordinated notes due 2007;

     - the related redemption premium of $2.0 million; and

     - the repayment of $26.3 million of indebtedness outstanding under our

                          DESCRIPTION OF THE NEW NOTES

GENERAL

     The form and terms of the new notes are the same as the form and terms of
the old notes, except that the new notes have been registered under the
Securities Act, will not bear legends restricting the transfer thereof, will not
be entitled to registration rights under the registration rights agreement, and
will not contain provisions relating to additional interest. Range Resources
Corporation will issue the new notes under an indenture among itself, the
Subsidiary Guarantors and Bank One, National Association, as trustee. The terms
of the new notes include those stated in the indenture and those made part of
the indenture by reference to the Trust Indenture Act of 1939.

     Certain terms used in this description are defined under the subheading
"-- Certain Definitions." In this description, the words "Range Resources" or
"the Company" refer only to Range Resources Corporation, and any successor
obligor on the notes, and not to any of its subsidiaries. As used in this
section, the term "notes" refers to both old notes and new notes.

     The old notes, the new notes and any additional notes issued from time to
time in accordance with the terms of the indenture will constitute a single
class of debt securities under the indenture. If the exchange offer is
consummated, holders of old notes who do not exchange new notes for their old
notes will vote together with holders of the new notes and, if applicable, any
holders of additional notes for all relevant purposes under the indenture.
Accordingly, in determining whether the required holders have given any notice,
consent or waiver or taken any other action permitted under the indenture, any
old notes that remain outstanding after the exchange offer will be aggregated
with the new notes and, if applicable, any additional notes, and the holders of
the old notes, the new notes and the additional notes will vote together as a
single class. All references in this prospectus to specified percentages in
aggregate principal amount of the notes that are outstanding means, at any time
after the exchange is consummated, the percentage in aggregate principal amount
of the old notes, the new notes and the additional notes then outstanding.

     The following description is a summary of the provisions of the indenture
that we believe to be material and of interest to you and does not restate that
agreement in its entirety. We encourage you to read the indenture because that
agreement, and not this description, will define your rights as a holder of the
notes. We have filed a copy of the indenture as an exhibit to the registration
statement of which this prospectus is a part.

BASIC TERMS OF NOTES

     The notes

     - are unsecured senior subordinated obligations of Range Resources,
       subordinated in right of payment to all existing and future Senior Debt
       of Range Resources in accordance with the subordination provisions of the
       indenture;

     - are jointly, severally and unconditionally guaranteed on a senior
       subordinated basis by each of the Restricted Subsidiaries of the Company
       and any future Restricted Subsidiary of the Company. The obligations of
       the Subsidiary Guarantors under the Guarantees will be general unsecured
       obligations of each of the Subsidiary Guarantors and will be subordinated
       in right of payment to all obligations of the Subsidiary Guarantors in
       respect of Senior Debt.

     - are issued in an original aggregate principal amount of $100,000,000;

     - mature on July 15, 2013;

                                        23


     - bear interest commencing the date of issue at 7 3/8%, payable
       semiannually in arrears on each January 15 and July 15, commencing
       January 15, 2004 to holders of record on the January 1 or July 1
       immediately preceding the interest payment date; and

     - bear interest on overdue principal, and, to the extent lawful, pay
       interest on overdue interest, at 1.0% per annum higher than 7 3/8%.

Interest will be computed on the basis of a 360-day year of twelve 30-day
months.

ADDITIONAL NOTES

     Subject to the covenants described below, the Company may issue additional
notes under the indenture having the same terms in all respects as the notes
except that interest will accrue on the additional notes from their date of
issuance.

     Any old notes not exchanged in the exchange offer, any new notes and any
additional notes would be treated as a single class for all purposes under the
indenture and will vote together as one class on all matters under the
indenture.

OPTIONAL REDEMPTION

     Except as otherwise described below, the notes will not be redeemable at
the Company's option prior to July 15, 2008. Thereafter, the notes will be
subject to redemption at the option of the Company, in whole or in part, upon
not less than 30 nor more than 60 days' notice, at the redemption prices
(expressed as percentages of principal amount) set forth below plus accrued and
unpaid interest thereon to the applicable redemption date, if redeemed during
the twelve-month period beginning on July 15 of the years indicated below:

</Table>

     Prior to July 15, 2006, the Company may, at its option, on any one or more
occasions, redeem up to 35% of the original aggregate principal amount of the
notes at a redemption price equal to 107.375% of the principal amount thereof,
plus accrued and unpaid interest, if any, thereon to the redemption date, with
all or a portion of the net proceeds of public sales of Equity Interests of the
Company; provided that at least 65% of the original aggregate principal amount
of the notes remains outstanding immediately after the occurrence of such
redemption; and provided, further, that such redemption shall occur within 60
days of the date of the closing of the related sale of such Equity Interests.

NO MANDATORY REDEMPTION OR SINKING FUND

     Except as set forth below under "-- Repurchase at the Option of Holders,"
the Company is not required to make mandatory redemption or sinking fund
payments with respect to the notes.

GUARANTEES

     The Company's payment obligations under the notes will be jointly,
severally and unconditionally guaranteed (the "Guarantees") by each Restricted
Subsidiary of the Company and any future Restricted Subsidiary of the Company.
The Subsidiary Guarantors shall initially be Range Energy I, Inc., Range HoldCo,
Inc., Range Production Company, Range Energy Ventures Corporation, Gulfstar
Energy, Inc. and Range Energy Finance Corporation. The Guarantees will be
subordinated to Indebtedness of the Subsidiary Guarantors to the same extent and
in the same manner as the notes are subordinated to the

                                        24


Senior Debt. Each Guarantee by a Subsidiary Guarantor will be limited in an
amount not to exceed the maximum amount that can be guaranteed by the applicable
Subsidiary Guarantor without rendering such Guarantee, as it relates to such
Subsidiary Guarantor, voidable under applicable law relating to fraudulent
conveyance or fraudulent transfer or similar laws affecting rights of creditors
generally.

     The indenture provides that no Subsidiary Guarantor may consolidate with or
merge with or into (whether or not such Subsidiary Guarantor is the surviving
Person), another Person whether or not affiliated with such Subsidiary
Guarantor, unless (i) subject to the provisions of the following paragraph, the
Person formed by or surviving any such consolidation or merger (if other than
such Subsidiary Guarantor) assumes all the obligations of such Subsidiary
Guarantor pursuant to a supplemental indenture in form and substance reasonably
satisfactory to the Trustee in respect of the notes, the indenture and the
Guarantees; (ii) immediately after giving effect to such transaction, no Default
or Event of Default exists; and (iii) such transaction does not violate any of
the covenants described under the heading "-- Certain Covenants."

     The indenture provides that in the event of a sale or other disposition of
all or substantially all of the assets of a Subsidiary Guarantor to a third
party or an Unrestricted Subsidiary in a transaction that does not violate any
of the covenants in the indenture, by way of merger, consolidation or otherwise,
or a sale or other disposition of all of the capital stock of a Subsidiary
Guarantor, then such Subsidiary Guarantor (in the event of a sale or other
disposition, by way of such a merger, consolidation or otherwise, of all of the
capital stock of such Subsidiary Guarantor) or the Person acquiring the property
(in the event of a sale or other disposition of all or substantially all of the
assets of such Subsidiary Guarantor) will be released from and relieved of any
obligations under its Guarantee; provided that the Net Proceeds of such sale or
other disposition are applied in accordance with the covenant described under
the caption "-- Repurchase at the Option of Holders -- Asset sales."

     Any Subsidiary Guarantor that is designated an Unrestricted Subsidiary in
accordance with the terms of the indenture shall be released and relieved of its
obligations under its Guarantee and any Unrestricted Subsidiary and any newly
formed or newly acquired Subsidiary that becomes a Restricted Subsidiary will be
required to execute a Guarantee in accordance with the terms of the indenture.

     The Company is a holding company, owns no operating assets and has no
significant operations independent of its subsidiaries. The Guarantees are full
and unconditional and joint and several, and any subsidiaries of the Company
other than the Subsidiary Guarantors are minor.

SUBORDINATION

     The payment of principal of, premium, if any, and interest on the notes and
any other payment obligations of the Company in respect of the notes (including
any obligation to repurchase the notes) will be subordinated in certain
circumstances in right of payment, as set forth in the indenture, to the prior
payment in full in cash of all Senior Debt, whether outstanding on the date of
the indenture or thereafter incurred.

     Upon any payment or distribution of property or securities to creditors of
the Company in a liquidation or dissolution of the Company or in a bankruptcy,
reorganization, insolvency, receivership or similar proceeding relating to the
Company or its property, or in an assignment for the benefit of creditors or any
marshalling of the Company's assets and liabilities, the holders of Senior Debt
will be entitled to receive payment in full of all Obligations due in respect of
such Senior Debt (including interest after the commencement of any such
proceeding at the rate specified in the applicable Senior Debt, whether or not a
claim for such interest would be allowed in such proceeding) before the Holders
of notes will be entitled to receive any payment with respect to the notes, and
until all Obligations with respect to Senior Debt are paid in full, any
distribution to which the Holders of notes would be entitled shall be made to
the holders of Senior Debt (except in each case that Holders of notes may
receive securities that are subordinated at least to the same extent as the
notes are subordinated to Senior Debt and any securities issued in exchange for
Senior Debt and payments made from the trust described under "-- Legal
Defeasance and Covenant Defeasance").
                                        25


     The Company may not make any payment (whether by redemption, purchase,
retirement, defeasance or otherwise) upon or in respect of the notes (except in
such subordinated securities or from the trust described under "-- Legal
Defeasance and Covenant Defeasance") if (i) a default in the payment of the
principal of, premium, if any, or interest on Designated Senior Debt occurs or
(ii) any other default occurs and is continuing with respect to Designated
Senior Debt that permits, or with the giving of notice or passage of time or
both (unless cured or waived) will permit, holders of the Designated Senior Debt
as to which such default relates to accelerate its maturity and the Trustee
receives a notice of such default (a "Payment Blockage Notice") from the Company
or the holders of any Designated Senior Debt. Cash payments on the notes shall
be resumed (a) in the case of a payment default, upon the date on which such
default is cured or waived and (b) in case of a nonpayment default, the earliest
of the date on which such nonpayment default is cured or waived, the date on
which the applicable Payment Blockage Notice is retracted by written notice to
the Trustee or 90 days after the date on which the applicable Payment Blockage
Notice is received, unless the maturity of any Designated Senior Debt has been
accelerated or a default of the type described in clause (ix) under the caption
"Events of Default" has occurred and is continuing. No new period of payment
blockage may be commenced unless and until 360 days have elapsed since the date
of commencement of the payment blockage period resulting from the immediately
prior Payment Blockage Notice. No nonpayment default in respect of Designated
Senior Debt that existed or was continuing on the date of delivery of any
Payment Blockage Notice to the Trustee shall be, or be made, the basis for a
subsequent Payment Blockage Notice.

     The indenture will further require that the Company promptly notify holders
of Senior Debt if payment of the notes is accelerated because of an Event of
Default.

     As a result of the subordination provisions described above, in the event
of a liquidation or insolvency of the Company, Holders of notes may recover less
ratably than creditors of the Company who are holders of Senior Debt. As of June
30, 2003, we had $184.1 million of Senior Debt outstanding, including our 50%
portion of indebtedness owed by our Great Lakes joint venture under its credit
facility. The indenture will limit, subject to certain financial tests, the
amount of additional Indebtedness, including Senior Debt, that the Company and
its Subsidiaries can incur. See "-- Certain Covenants -- Incurrence of
indebtedness and issuance of disqualified stock."

REPURCHASE AT THE OPTION OF HOLDERS

  CHANGE OF CONTROL

     Upon the occurrence of a Change of Control, each Holder of notes will have
the right to require the Company to repurchase all or any part (equal to $1,000
or an integral multiple thereof) of such Holder's notes pursuant to the offer
described below (the "Change of Control Offer") at an offer price in cash equal
to 101% of the aggregate principal amount of the notes plus accrued and unpaid
interest, if any, thereon to the date of purchase (the "Change of Control
Payment"). Within 30 days following any Change of Control, the Company will mail
a notice to each Holder describing the transaction or transactions that
constitute the Change of Control and offer to repurchase the notes pursuant to
the procedures required by the indenture and described in such notice. The
Change of Control Payment shall be made on a business day not less than 30 days
nor more than 60 days after such notice is mailed (the "Change of Control
Payment Date"). 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 the notes as a result of a Change of Control.

     On the Change of Control Payment Date, the Company will, to the extent
lawful, (i) accept for payment all the notes or portions thereof properly
tendered pursuant to the Change of Control Offer, (ii) deposit with the Paying
Agent an amount equal to the Change of Control Payment in respect of all the
notes or portions thereof so tendered and (iii) deliver or cause to be delivered
to the Trustee the notes so accepted together with an Officers' Certificate
stating the aggregate principal amount of such notes or portions thereof being
purchased by the Company. The Paying Agent will promptly mail to each Holder of

                                        26


notes so tendered the Change of Control Payment for such notes, and the Trustee
will promptly authenticate and mail (or cause to be transferred by book entry)
to each Holder a new note equal in principal amount to any unpurchased portion
of the notes surrendered, if any; provided that each such new note will be in a
principal amount of $1,000 or an integral multiple thereof. The Company will
publicly announce the results of the Change of Control Offer on or as soon as
practicable after the Change of Control Payment Date.

     Except as described above with respect to a Change of Control, the
indenture does not contain provisions that permit the Holders of notes to
require that the Company repurchase or redeem the notes in the event of a
takeover, recapitalization or similar transaction.

     The Company will not be required to make a Change of Control Offer if a
third party makes the Change of Control Offer in the manner, at the times and
otherwise in compliance with the requirements set forth in the indenture
applicable to a Change of Control Offer made by the Company and purchases all
notes (or portions thereof) validly tendered and not withdrawn under such Change
of Control Offer.

     The Credit Agreement prohibits the Company from repurchasing any notes
pursuant to a Change of Control Offer prior to the repayment in full of the
Senior Debt under the Credit Agreement. Moreover, the occurrence of certain
change of control events identified in the Credit Agreement will constitute a
default under the Credit Agreement. Any future Credit Facilities or other
agreements relating to the Senior Debt to which the Company becomes a party may
contain similar restrictions and provisions. If a Change of Control were to
occur, the Company may not have sufficient available funds to pay the Change of
Control Payment for all notes that might be delivered by Holders of notes
seeking to accept the Change of Control Offer after first satisfying its
obligations under the Credit Agreement or other agreements relating to Senior
Debt, if accelerated. The failure of the Company to make or consummate the
Change of Control Offer or pay the Change of Control Payment when due will
constitute a Default under the indenture and will otherwise give the Trustee and
the Holders of notes the rights described under "-- Events of Default and
Remedies."

     The definition of Change of Control includes a phrase relating to the sale,
lease, transfer, conveyance or other disposition of "all or substantially all"
of the assets of the Company and its Subsidiaries taken as a whole. Although
there is a developing body of case law interpreting the phrase "substantially
all," there is no precise established definition of the phrase under applicable
law. Accordingly, the ability of a Holder of notes to require the Company to
repurchase such notes as a result of a sale, lease, transfer, conveyance or
other disposition of less than all of the assets of the Company and its
Subsidiaries taken as a whole to another Person or group may be uncertain.

  ASSET SALES

     The indenture provides that the Company will not, and will not permit any
of its Restricted Subsidiaries to, engage in an Asset Sale unless (i) the
Company or the Restricted Subsidiary, as the case may be, receives consideration
at the time of such Asset Sale at least equal to the fair market value (as
determined in good faith by a resolution of the Board of Directors set forth in
an Officers' Certificate delivered to the Trustee, which determination shall be
conclusive evidence of compliance with this provision) of the assets or Equity
Interests issued or sold or otherwise disposed of and (ii) at least 85% of the
consideration therefor received by the Company or such Restricted Subsidiary in
such Asset Sale, plus all other Asset Sales since the date of the indenture, on
a cumulative basis, is in the form of cash or Cash Equivalents; provided that
the amount of any liabilities (as shown on the Company's or such Restricted
Subsidiary's most recent balance sheet) of the Company or any Restricted
Subsidiary (other than contingent liabilities and liabilities that are by their
terms subordinated to the notes or any guarantee thereof) are assumed by the
transferee of any such assets pursuant to a customary novation agreement that
releases the Company or such Restricted Subsidiary from further liability.

     Within 360 days after the receipt of any Net Proceeds from an Asset Sale,
the Company may apply such Net Proceeds, at its option, (a) to reduce Senior
Debt, (b) to acquire a controlling interest in another Oil and Gas Business, (c)
to make capital expenditures in respect of the Company's or its
                                        27


Restricted Subsidiaries' Oil and Gas Business, (d) to purchase long-term assets
that are used or useful in such Oil and Gas Business or (e) to repurchase any
notes. Pending the final application of any such Net Proceeds, the Company may
temporarily reduce Senior Debt that is revolving debt or otherwise invest such
Net Proceeds in any manner that is not prohibited by the indenture. Any Net
Proceeds from Asset Sales that are not applied as provided in the first sentence
of this paragraph will (after the expiration of the periods specified in this
paragraph) be deemed to constitute "Excess Proceeds."

     When the aggregate amount of Excess Proceeds exceeds $10 million, the
Company will be required to make an offer to all Holders of notes and, to the
extent required by the terms thereof, to all holders or lenders of Pari Passu
Indebtedness (an "Asset Sale Offer") to purchase the maximum principal amount of
the notes and any such Pari Passu Indebtedness to which the Asset Sale Offer
applies that may be purchased out of the Excess Proceeds, at an offer price in
cash equal to 100% of the principal amount thereof plus accrued and unpaid
interest thereon to the date of purchase, or, in the case of any other Pari
Passu Indebtedness, 100% of the principal amount thereof (or with respect to
discount Pari Passu Indebtedness, the accreted value thereof) on the date of
purchase, in each case in accordance with the procedures set forth in the
indenture or the agreements governing the Pari Passu Indebtedness, as
applicable. To the extent that the aggregate principal amount (or accreted
value, as the case may be) of the notes and Pari Passu Indebtedness tendered
pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Company
may use any remaining Excess Proceeds for general corporate purposes. If the
aggregate principal amount of the notes surrendered by Holders thereof and the
aggregate principal amount or accreted value of other Pari Passu Indebtedness
surrendered by holders or lenders thereof, collectively, exceeds the amount of
Excess Proceeds, the Trustee and the trustee or other lender representatives for
the Pari Passu Indebtedness shall select the notes and other Pari Passu
Indebtedness to be purchased on a pro rata basis, based on the aggregate
principal amount (or accreted value, as applicable) thereof surrendered in such
Asset Sale Offer. Upon completion of such Asset Sale Offer, the amount of Excess
Proceeds shall be reset at zero.

     The Credit Agreement prohibits the Company from purchasing any notes from
the Net Proceeds of Asset Sales. Any future credit agreements or other
agreements relating to Senior Debt to which the Company becomes a party may
contain similar restrictions and provisions. In the event an Asset Sale Offer
occurs at a time when the Company is prohibited from purchasing the notes, the
Company could seek the consent of its lenders to the purchase or could attempt
to refinance the Senior Debt that contain such prohibition. If the Company does
not obtain such a consent or repay such Senior Debt, the Company may remain
prohibited from purchasing the notes. In such case, the Company's failure to
purchase tendered notes would constitute an Event of Default under the indenture
which would, in turn, constitute a default under the Credit Agreement and
possibly a default under other agreements relating to Senior Debt. In such
circumstances, the subordination provisions in the indenture would likely
restrict payments to the Holders of the notes.

CERTAIN COVENANTS

     The indenture contains covenants including, among others, the following:

  RESTRICTED PAYMENTS

     The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly:

          (i) declare or pay any dividend or make any other payment or
     distribution on account of the Company's Equity Interests (including,
     without limitation, any payment to holders of the Company's Equity
     Interests in connection with any merger or consolidation involving the
     Company) to the direct or indirect holders of the Company's Equity
     Interests in their capacity as such (other than dividends or distributions
     payable in Equity Interests (other than Disqualified Stock) of the
     Company);

          (ii) purchase, redeem or otherwise acquire or retire for value any
     Equity Interests of the Company or any direct or indirect parent or other
     Affiliate of the Company that is not a Wholly Owned Restricted Subsidiary
     of the Company;
                                        28


          (iii) make any principal payment on, or purchase, redeem, defease or
     otherwise acquire or retire for value any Indebtedness that is subordinated
     to the notes, except at final maturity; or

          (iv) make any Restricted Investment (all such payments and other
     actions set forth in clauses (i) through (iv) above being collectively
     referred to as "Restricted Payments"), unless, at the time of and after
     giving effect to such Restricted Payment:

             (a) no Default or Event of Default shall have occurred and be
        continuing or would occur as a consequence thereof; and

             (b) the Company would, at the time of such Restricted Payment and
        after giving pro forma effect thereto as if such Restricted Payment had
        been made at the beginning of the applicable four-quarter period, have
        been permitted to incur at least $1.00 of additional Indebtedness
        pursuant to the Fixed Charge Coverage Ratio test set forth in the first
        paragraph of the covenant described below under the caption
        "-- Incurrence of indebtedness and issuance of disqualified stock"; and

             (c) such Restricted Payment, together with the aggregate of all
        other Restricted Payments made by the Company and its Restricted
        Subsidiaries after the date of the indenture (excluding Restricted
        Payments permitted by clauses (2), (3), (5), (6) and (7) of the next
        succeeding paragraph), is less than the sum of (i) 50% of the
        Consolidated Net Income of the Company for the period (taken as one
        accounting period) from the beginning of the first fiscal quarter
        commencing prior to the date of the indenture to the end of the
        Company's most recently ended fiscal quarter for which internal
        financial statements are available at the time of such Restricted
        Payment (or, if such Consolidated Net Income for such period is a
        deficit, less 100% of such deficit), plus (ii) 100% of the aggregate net
        cash proceeds received by the Company from the issue and sale since the
        date of the indenture of Equity Interests of the Company or of debt
        securities of the Company that have been converted into or exchanged for
        such Equity Interests (other than Equity Interests (or convertible debt
        securities) sold to a Subsidiary of the Company and other than
        Disqualified Stock or debt securities that have been converted into
        Disqualified Stock), plus (iii) to the extent that any Restricted
        Investment that was made after the date of the indenture is sold for
        cash or otherwise liquidated or repaid for cash, the lesser of (A) the
        net proceeds of such sale, liquidation or repayment and (B) the initial
        amount of such Restricted Investment; provided, however, that the
        foregoing provisions of this paragraph (c) will not prohibit Restricted
        Payments in an aggregate amount not to exceed $20 million.

     The foregoing provisions will not prohibit:

          (1) the payment of any dividend within 60 days after the date of
     declaration thereof, if at said date of declaration such payment would have
     complied with the provisions of the indenture;

          (2) the redemption, repurchase, retirement or other acquisition of any
     Equity Interests of the Company in exchange for, or out of the proceeds of,
     the substantially concurrent sale (other than to a Subsidiary of the
     Company) of other Equity Interests of the Company (other than any
     Disqualified Stock); provided that the amount of any such net cash proceeds
     that are utilized for any such redemption, repurchase, retirement or other
     acquisition shall be excluded from clause (c)(ii) of the preceding
     paragraph;

          (3) the defeasance, redemption or repurchase of Subordinated
     Indebtedness with the net cash proceeds from an incurrence of subordinated
     Permitted Refinancing Debt or the substantially concurrent sale (other than
     to a Subsidiary of the Company) of Equity Interests of the Company (other
     than Disqualified Stock); provided that the amount of any such net cash
     proceeds that are utilized for any such redemption, repurchase, retirement
     or other acquisition shall be excluded from clause (c)(ii) of the preceding
     paragraph;

          (4) the repurchase, redemption or other acquisition or retirement for
     value of any Equity Interests of the Company or any Subsidiary of the
     Company held by any of the Company's (or any of

                                        29


     its Subsidiaries') employees pursuant to any management equity subscription
     agreement or stock option agreement in effect as of the date of the
     indenture; provided that the aggregate price paid for all such repurchased,
     redeemed, acquired or retired Equity Interests shall not exceed $2 million
     in any twelve-month period; and provided further that no Default or Event
     of Default shall have occurred and be continuing immediately after such
     transaction;

          (5) repurchases of Equity Interests deemed to occur upon exercise of
     stock options if such Equity Interests represent a portion of the exercise
     price of such options;

          (6) cash payments made by the Company for the repurchase, redemption
     or other acquisition or retirement of the 8 3/4% Senior Subordinated Notes;
     and

          (7) cash payments made by the Company, not to exceed $25 million in
     the aggregate, for the repurchase, redemption or other acquisition or
     retirement of the 6% Convertible Subordinated Debentures and the 5 3/4%
     Trust Convertible Preferred Securities.

     The amount of all Restricted Payments (other than cash) shall be the fair
market value (as determined in good faith by a resolution of the Board of
Directors set forth in an Officers' Certificate delivered to the Trustee, which
determination shall be conclusive evidence of compliance with this provision) on
the date of the Restricted Payment of the asset(s) proposed to be transferred by
the Company or the applicable Restricted Subsidiary, as the case may be,
pursuant to the Restricted Payment. Not later than five days after the date of
making any Restricted Payment, the Company shall deliver to the Trustee an
Officers' Certificate stating that such Restricted Payment is permitted and
setting forth the basis upon which the calculations required by the covenant
"Restricted Payments" were computed.

  DESIGNATION OF UNRESTRICTED SUBSIDIARIES

     The Board of Directors of the Company may designate any Restricted
Subsidiary to be an Unrestricted Subsidiary if such designation would not cause
a Default. For purposes of making such determination, all outstanding
Investments by the Company and its Restricted Subsidiaries (except to the extent
repaid in cash) in the Subsidiary so designated will be deemed to be Restricted
Payments at the time of such designation and will reduce the amount available
for Restricted Payments under clause (c) of the first paragraph of the covenant
"Restricted Payments." All such outstanding Investments will be deemed to
constitute Investments in an amount equal to the greater of the fair market
value or the book value of such Investments at the time of such designation.
Such designation will only be permitted if such Restricted Payment would be
permitted at such time and if such Restricted Subsidiary otherwise meets the
definition of an Unrestricted Subsidiary.

  INCURRENCE OF INDEBTEDNESS AND ISSUANCE OF DISQUALIFIED STOCK

     The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee
or otherwise become directly or indirectly liable, contingently or otherwise,
with respect to (collectively, "incur") any Indebtedness (including Acquired
Debt) and the Company will not issue any Disqualified Stock and will not permit
any of its Restricted Subsidiaries to issue any shares of preferred stock;
provided, however, that the Company may incur Indebtedness (including Acquired
Debt) or issue shares of Disqualified Stock if:

          (i) the Fixed Charge Coverage Ratio for the Company's most recently
     ended four full fiscal quarters for which internal financial statements are
     available immediately preceding the date on which such additional
     Indebtedness is incurred or such Disqualified Stock is issued would have
     been at least 2.5 to 1, determined on a pro forma basis as set forth in the
     definition of Fixed Charge Coverage Ratio; and

          (ii) no Default or Event of Default shall have occurred and be
     continuing at the time such additional Indebtedness is incurred or such
     Disqualified Stock is issued or would occur as a consequence of the
     incurrence of the additional Indebtedness or the issuance of the
     Disqualified Stock.
                                        30


     Notwithstanding the foregoing, the indenture does not prohibit any of the
     following (collectively, "Permitted Indebtedness"):

          (a) the Indebtedness evidenced by the notes;

          (b) the incurrence by the Company or any of its Restricted
     Subsidiaries of Indebtedness pursuant to Credit Facilities, so long as the
     aggregate principal amount of all Indebtedness outstanding under all Credit
     Facilities does not, at any one time, exceed the greater of (i) $225
     million (or, if there is any permanent reduction in the aggregate principal
     amount permitted to be borrowed under the Credit Agreement, such lesser
     aggregate principal amount) and (ii) an amount equal to the sum of (A) $50
     million plus (B) 30% of Adjusted Consolidated Net Tangible Assets
     determined after the incurrence of such Indebtedness (including the
     application of the proceeds therefrom);

          (c) the guarantee by any Subsidiary Guarantor of any Indebtedness that
     is permitted by the indenture to be incurred by the Company;

          (d) all Indebtedness of the Company and its Restricted Subsidiaries in
     existence as of the date of the indenture;

          (e) intercompany Indebtedness between or among the Company and any of
     its Wholly Owned Restricted Subsidiaries; provided, however, that (i) if
     the Company is the obligor on such Indebtedness, such Indebtedness is
     expressly subordinate to the payment in full of all Obligations with
     respect to the notes and (ii)(A) any subsequent issuance or transfer of
     Equity Interests that results in any such Indebtedness being held by a
     Person other than the Company or a Wholly Owned Restricted Subsidiary and
     (B) any sale or other transfer of any such Indebtedness to a Person that is
     not either the Company or a Wholly Owned Restricted Subsidiary shall be
     deemed, in each case, to constitute an incurrence of such Indebtedness by
     the Company or such Restricted Subsidiary, as the case may be;

          (f) Indebtedness in connection with one or more standby letters of
     credit, guarantees, performance bonds or other reimbursement obligations,
     in each case, issued in the ordinary course of business and not in
     connection with the borrowing of money or the obtaining of advances or
     credit (other than advances or credit on open account, includible in
     current liabilities, for goods and services in the ordinary course of
     business and on terms and conditions which are customary in the Oil and Gas
     Business, and other than the extension of credit represented by such letter
     of credit, guarantee or performance bond itself), not to exceed in the
     aggregate at any given time 5% of Total Assets;

          (g) Indebtedness under Interest Rate Hedging Agreements entered into
     for the purpose of limiting interest rate risks, provided that the
     obligations under such agreements are related to payment obligations on
     Indebtedness otherwise permitted by the terms of this covenant and that the
     aggregate notional principal amount of such agreements does not exceed 105%
     of the principal amount of the Indebtedness to which such agreements
     relate;

          (h) Indebtedness under Oil and Gas Hedging Contracts, provided that
     such contracts were entered into in the ordinary course of business for the
     purpose of limiting risks that arise in the ordinary course of business of
     the Company and its Restricted Subsidiaries;

          (i) the incurrence by the Company of Indebtedness not otherwise
     permitted to be incurred pursuant to this paragraph, provided that the
     aggregate principal amount (or accreted value, as applicable) of all
     Indebtedness incurred pursuant to this clause (i), together with all
     Permitted Refinancing Debt incurred pursuant to clause (j) of this
     paragraph in respect of Indebtedness previously incurred pursuant to this
     clause (i), does not exceed $10 million at any one time outstanding;

          (j) Permitted Refinancing Debt incurred in exchange for, or the net
     proceeds of which are used to refinance, extend, renew, replace, defease or
     refund, Indebtedness that was permitted by the indenture to be incurred
     (including Indebtedness previously incurred pursuant to this clause (j));
                                        31


          (k) accounts payable or other obligations of the Company or any
     Restricted Subsidiary to trade creditors created or assumed by the Company
     or such Restricted Subsidiary in the ordinary course of business in
     connection with the obtaining of goods or services;

          (l) Indebtedness consisting of obligations in respect of purchase
     price adjustments, guarantees or indemnities in connection with the
     acquisition or disposition of assets; and

          (m) production imbalances that do not, at any one time outstanding,
     exceed 2% of the Total Assets of the Company.

     The Company will not permit any Unrestricted Subsidiary to incur any
Indebtedness other than Non-Recourse Debt; provided, however, if any such
Indebtedness ceases to be Non-Recourse Debt, such event shall be deemed to
constitute an incurrence of Indebtedness by the Company.

  NO LAYERING

     The indenture provides that (i) the Company will not incur, create, issue,
assume, guarantee or otherwise become liable for any Indebtedness that is
subordinate or junior in right of payment to any Senior Debt and senior in any
respect in right of payment to the notes and (ii) the Subsidiary Guarantors will
not directly or indirectly incur, create, issue, assume, guarantee or otherwise
become liable for any Indebtedness that is subordinate or junior in right of
payment to any Senior Debt and senior in any respect in right of payment to the
Guarantees, provided, however, that the foregoing limitations will not apply to
distinctions between categories of Indebtedness that exist by reason of any
Liens arising or created in respect of some but not all such Indebtedness.

  LIENS

     The Company will not, and will not permit any of its Restricted
Subsidiaries to, create, incur, assume or otherwise cause or suffer to exist or
become effective any Lien securing Indebtedness of any kind (other than
Permitted Liens) upon any of its property or assets, now owned or hereafter
acquired, unless all payments under the notes are secured by such Lien prior to,
or on an equal and ratable basis with, the Indebtedness so secured for so long
as such Indebtedness is secured by such Lien.

  DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING SUBSIDIARIES

     The Company will not, and will not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to
exist or become effective any encumbrance or restriction on the ability of any
Restricted Subsidiary to (i)(x) pay dividends or make any other distributions to
the Company or any of its Restricted Subsidiaries (1) on its Capital Stock or
(2) with respect to any other interest or participation in, or measured by, its
profits, or (y) pay any indebtedness owed by it to the Company or any of its
Restricted Subsidiaries, (ii) make loans or advances to the Company or any of
its Restricted Subsidiaries or (iii) transfer any of its properties or assets to
the Company or any of its Restricted Subsidiaries, except for such encumbrances
or restrictions existing under or by reason of (a) the Credit Agreement as in
effect as of the date of the indenture, and any amendments, modifications,
restatements, renewals, increases, supplements, refundings, replacements or
refinancings thereof or any other Credit Facility, provided that such
amendments, modifications, restatements, renewals, increases, supplements,
refundings, replacements, refinancings or other Credit Facilities are no more
restrictive taken as a whole with respect to such dividend and other payment
restrictions than those contained in the Credit Agreement as in effect on the
date of the indenture, (b) the indenture and the notes, (c) applicable law, (d)
any instrument governing Indebtedness or Capital Stock of a Person acquired by
the Company or any of its Restricted Subsidiaries as in effect at the time of
such acquisition (except, in the case of Indebtedness, to the extent such
Indebtedness was incurred in connection with or in contemplation of such
acquisition), which encumbrance or restriction is not applicable to any Person,
or the properties or assets

                                        32


of any Person, other than the Person and its Subsidiaries, or the property or
assets of the Person and its Subsidiaries, so acquired, provided that, in the
case of Indebtedness, such Indebtedness was permitted by the terms of the
indenture to be incurred, (e) by reason of customary non-assignment provisions
in leases and customary provisions in other agreements that restrict assignment
of such agreement or rights thereunder, entered into in the ordinary course of
business and consistent with past practices, (f) purchase money obligations for
property acquired in the ordinary course of business that impose restrictions of
the nature described in clause (iii) above on the property so acquired, or (g)
Permitted Refinancing Debt, provided that the restrictions contained in the
agreements governing such Permitted Refinancing Debt are no more restrictive
than those contained in the agreements governing the Indebtedness being
refinanced.

  MERGER, CONSOLIDATION OR SALE OF ASSETS

     The Company may not consolidate or merge with or into (whether or not the
Company is the surviving corporation), or sell, assign, transfer, lease, convey
or otherwise dispose of all or substantially all of its properties or assets, in
one or more related transactions, to another Person, and the Company may not
permit any of its Restricted Subsidiaries to enter into any such transaction or
series of transactions if such transaction or series of transactions would, in
the aggregate, result in a sale, assignment, transfer, lease, conveyance, or
other disposition of all or substantially all of the properties or assets of the
Company to another Person, in either case unless

          (i) the Company is the surviving corporation or the Person formed by
     or surviving any such consolidation or merger (if other than the Company)
     or to which such sale, assignment, transfer, lease, conveyance or other
     disposition shall have been made (the "Surviving Entity") is a corporation
     organized or existing under the laws of the United States, any state
     thereof or the District of Columbia;

          (ii) the Surviving Entity (if the Company is not the continuing
     obligor under the indenture) assumes all the obligations of the Company
     under the notes and the indenture pursuant to a supplemental indenture in a
     form reasonably satisfactory to the Trustee;

          (iii) immediately before and after giving effect to such transaction
     or series of transactions no Default or Event of Default exists;

          (iv) immediately after giving effect to such transaction or a series
     of transactions on a pro forma basis (and treating any Indebtedness not
     previously an obligation of the Company and its Subsidiaries which becomes
     the obligation of the Company or any of its Subsidiaries as a result of
     such transaction or series of transactions as having been incurred at the
     time of such transaction or series of transactions), the Consolidated Net
     Worth of the Company and its Subsidiaries or the Surviving Entity (if the
     Company is not the continuing obligor under the indenture) is equal to or
     greater than the Consolidated Net Worth of the Company and its Subsidiaries
     immediately prior to such transaction or series of transactions and

          (v) the Company or the Surviving Entity (if the Company is not the
     continuing obligor under the indenture) will, at the time of such
     transaction or series of transactions and after giving pro forma effect
     thereto as if such transaction or series of transactions had occurred at
     the beginning of the applicable four-quarter period, be permitted to incur
     at least $1.00 of additional Indebtedness pursuant to the test set forth in
     the first paragraph of the covenant described above under the caption
     "-- Incurrence of indebtedness and issuance of disqualified stock."

Notwithstanding the restrictions described in the foregoing clauses (iv) and
(v), any Restricted Subsidiary may consolidate with, merge into or transfer all
or part of its properties and assets to the Company, and any Wholly Owned
Restricted Subsidiary may consolidate with, merge into or transfer all or part
of its properties and assets to another Wholly Owned Restricted Subsidiary.

                                        33


  TRANSACTIONS WITH AFFILIATES

     The Company will not, and will not permit any of its Subsidiaries to, make
any payment to, or sell, lease, transfer or otherwise dispose of any of its
properties or assets to, or purchase any property or assets from, or enter into
or make or amend any contract, agreement, understanding, loan, advance or
guarantee with, or for the benefit of, any of its Affiliates (each of the
foregoing, an "Affiliate Transaction"), unless

          (i) such Affiliate Transaction is on terms that are no less favorable
     to the Company or the relevant Subsidiary than those that would have been
     obtained in a comparable transaction by the Company or such Subsidiary with
     an unrelated Person and

          (ii) the Company delivers to the Trustee

             (a) with respect to any Affiliate Transaction or series of related
        Affiliate Transactions involving aggregate consideration in excess of
        $1.0 million but less than or equal to $5.0 million, an Officers'
        Certificate certifying that such Affiliate Transaction complies with
        clause (i) above,

             (b) with respect to any Affiliate Transaction or series of related
        Affiliate Transactions involving aggregate consideration in excess of
        $5.0 million but less than or equal to $10.0 million, a resolution of
        the Board of Directors set forth in an Officers' Certificate certifying
        that such Affiliate Transaction or series of Affiliate Transactions
        complies with clause (i) above and that such Affiliate Transaction or
        series of Affiliate Transactions has been approved in good faith by a
        majority of the members of the Board of Directors who are disinterested
        with respect to such Affiliate Transaction or series of related
        Affiliate Transactions, which resolution shall be conclusive evidence of
        compliance with this provision, and

             (c) with respect to any Affiliate Transaction or series of related
        Affiliate Transactions involving aggregate consideration in excess of
        $10.0 million, (x) a resolution of the Board of Directors set forth in
        an Officers' Certificate certifying that such Affiliate Transaction or
        series of related Affiliate Transactions complies with clause (i) above
        and that such Affiliate Transaction or series of related Affiliate
        Transactions has been approved in good faith by a resolution adopted by
        a majority of the members of the Board of Directors of the Company who
        are disinterested with respect to such Affiliate Transaction or series
        of related Affiliate Transactions and (y) an opinion as to the fairness
        to the Company or such Subsidiary of such Affiliate Transaction or
        series of related Affiliate Transactions from a financial point of view
        issued by an accounting, appraisal, engineering or investment banking
        firm of national standing (which resolution and fairness opinion shall
        be conclusive evidence of compliance with this provision);

provided that the following shall not be deemed Affiliate Transactions:

     (1) transactions contemplated by any employment agreement or other
compensation plan or arrangement entered into by the Company or any of its
Subsidiaries in the ordinary course of business and consistent with the past
practice of the Company or such Subsidiary,

     (2) transactions between or among the Company and/or its Restricted
Subsidiaries,

     (3) Restricted Payments and Permitted Investments that are permitted by the
provisions of the indenture described above under the caption "-- Restricted
payments," and

     (4) indemnification payments made to officers, directors and employees of
the Company or any Subsidiary pursuant to charter, bylaw, statutory or
contractual provisions.

  ADDITIONAL SUBSIDIARY GUARANTEES

     If the Company or any of its Restricted Subsidiaries acquires or creates
another Restricted Subsidiary after the date of the indenture, then such newly
acquired or created Restricted Subsidiary will be required to execute a
Guarantee and deliver an opinion of counsel, in accordance with the terms of the
indenture.

                                        34


  BUSINESS ACTIVITIES

     The Company will not, and will not permit any Restricted Subsidiary to,
engage in any material respect in any business other than the Oil and Gas
Business.

  COMMISSION REPORTS

     Notwithstanding that the Company may not be required to remain subject to
the reporting requirements of Section 13 or 15(d) of the Exchange Act, to the
extent permitted by the Exchange Act the Company will file with the Commission
and provide, within 15 days after such filing, the Trustee and Holders and
prospective Holders (upon request) with the annual reports and the information,
documents and other reports which are specified in Sections 13 and 15(d) of the
Exchange Act (but without exhibits in the case of the Holders and prospective
Holders). In the event that the Company is not permitted to file such reports,
documents and information with the Commission, the Company will provide
substantially similar information to the Trustee, the Holders, and prospective
Holders (upon request) as if the Company were subject to the reporting
requirements of Section 13 or 15(d) of the Exchange Act. The Company also will
comply with the other provisions of Section 314(a) of the Trust Indenture Act.

EVENTS OF DEFAULT AND REMEDIES

     Each of the following constitutes an Event of Default:

          (i) a default for 30 days in the payment when due of interest on the
     notes (whether or not prohibited by the subordination provisions of the
     indenture);

          (ii) a default in payment when due of the principal of or premium, if
     any, on the notes (whether or not prohibited by the subordination
     provisions of the indenture);

          (iii) the failure by the Company to comply with its obligations under
     "Certain Covenants -- Merger, consolidation or sale of assets" above;

          (iv) the failure by the Company for 30 days after notice from the
     Trustee or the Holders of at least 25% in principal amount of the notes
     then outstanding to comply with the provisions described under the captions
     "Repurchase at the Option of Holders" and "Certain Covenants" other than
     the provisions described under "-- Merger, consolidation or sale of
     assets";

          (v) failure by the Company for 60 days after notice from the Trustee
     or the Holders of at least 25% in principal amount of the notes then
     outstanding to comply with any of its other agreements in the indenture or
     the notes;

          (vi) except as permitted by the indenture, any Guarantee shall be held
     in any judicial proceeding to be unenforceable or invalid or shall cease
     for any reason to be in full force and effect or a Subsidiary Guarantor, or
     any Person acting on behalf of such Subsidiary Guarantor, shall deny or
     disaffirm its obligations under its Guarantee;

          (vii) a default under any mortgage, indenture or instrument under
     which there may be issued or by which there may be secured or evidenced any
     Indebtedness for money borrowed by the Company or any of its Restricted
     Subsidiaries (or the payment of which is guaranteed by the Company or any
     of its Restricted Subsidiaries) whether such Indebtedness or guarantee
     existed on the date of the indenture or was created thereafter, which
     default

             (a) is caused by a failure to pay principal of or premium, if any,
        or interest on such Indebtedness prior to the expiration of the grace
        period provided in such Indebtedness on the date of such default (a
        "Payment Default"), or

             (b) results in the acceleration of such Indebtedness prior to its
        express maturity,

        and, in each case, the principal amount of any such Indebtedness,
        together with the principal amount of any other such Indebtedness under
        which there is then existing a Payment Default or

                                        35


        the maturity of which has been so accelerated, aggregates $10 million or
        more; provided, that if any such default is cured or waived or any such
        acceleration is rescinded, or such Indebtedness is repaid, within a
        period of 10 days from the continuation of such default beyond the
        applicable grace period or the occurrence of such acceleration, as the
        case may be, such Event of Default under the indenture and any
        consequential acceleration of the notes shall be automatically
        rescinded;

          (viii) the failure by the Company or any of its Restricted
     Subsidiaries to pay final, non-appealable judgments aggregating in excess
     of $10 million, which judgments remain unpaid or discharged for a period of
     60 days; and

          (ix) certain events of bankruptcy or insolvency with respect to the
     Company or any of its Significant Subsidiaries or any group of Subsidiaries
     that, taken together, would constitute a Significant Subsidiary.

     If any Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the notes then outstanding may
declare the principal of and accrued but unpaid interest on such notes to be due
and payable immediately. Notwithstanding the foregoing, in the case of an Event
of Default arising from certain events of bankruptcy or insolvency, with respect
to the Company or any Significant Subsidiary or any group of Subsidiaries that,
taken together, would constitute a Significant Subsidiary, all outstanding notes
will become due and payable without further action or notice. Holders of notes
may not enforce the indenture or notes except as provided in the indenture.
Subject to certain limitations, Holders of a majority in principal amount of the
notes then outstanding may direct the Trustee in its exercise of any trust or
power. The Trustee may withhold from Holders of notes notice of any continuing
Default or Event of Default (except a Default or Event of Default relating to
the payment of principal or interest) if it determines that withholding notice
is in their interest.

     The Holders of a majority in principal amount of the notes then outstanding
by notice to the Trustee may on behalf of the Holders of all of the notes waive
any existing Default or Event of Default and its consequences under the
indenture except a continuing Default or Event of Default in the payment of
interest or premium on, or the principal of, the notes.

     The Company is required to deliver to the Trustee annually a statement
regarding compliance with the indenture, and the Company is required, within
five business days of becoming aware of any Default or Event of Default, to
deliver to the Trustee a statement specifying such Default or Event of Default.

NO LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES, INCORPORATORS, MEMBERS AND
STOCKHOLDERS

     No director, officer, employee, incorporator, member or stockholder of the
Company or any Guarantor, as such, will have any liability for any obligations
of the Company or such Guarantor under the notes, any Note Guaranty or the
indenture or for any claim based on, in respect of, or by reason of, such
obligations. Each holder of notes by accepting a note waives and releases all
such liability. The waiver and release are part of the consideration for
issuance of the notes. This waiver may not be effective to waive liabilities
under the federal securities laws and it is the view of the Commission that such
a waiver is against public policy.

AMENDMENTS, SUPPLEMENTS AND WAIVERS

     Except as provided in the next two succeeding paragraphs, the indenture,
the notes or the Guarantees may be amended or supplemented with the consent of
the Holders of at least a majority in principal amount of the notes then
outstanding (including, without limitation, consents obtained in connection with
a purchase of, or tender offer or exchange offer for, the notes), and any
existing default or compliance with any provision of such indenture, the notes
or the Guarantees may be waived with the consent of the Holders of a majority in
principal amount of the then outstanding notes (including consents obtained in
connection with a tender offer or exchange offer for the notes).

                                        36


     Without the consent of each Holder affected, an amendment or waiver may not
(with respect to any the notes held by a non-consenting Holder):

          (i) reduce the principal amount of the notes whose Holders must
     consent to an amendment, supplement or waiver,

          (ii) reduce the principal of or change the fixed maturity of any note
     or alter the provisions with respect to the redemption of the notes (other
     than provisions relating to the covenants described above under the caption
     "--Repurchase at the Option of Holders"),

          (iii) reduce the rate of or change the time for payment of interest on
     any note,

          (iv) waive a Default or Event of Default in the payment of principal
     of or premium, if any, or interest on the notes (except a recision of
     acceleration of the notes by the Holders of at least a majority in
     principal amount of such notes and a waiver of the payment default that
     resulted from such acceleration),

          (v) make any note payable in money other than that stated in the
     notes,

          (vi) make any change in the provisions of the indenture relating to
     waivers of past Defaults or the rights of Holders of notes to receive
     payments of principal of or premium, if any, or interest on the notes, or

          (vii) make any change in the foregoing amendment and waiver
     provisions.

In addition, any amendment to the provisions described under "-- Repurchase at
the Option of Holders" or the provisions of Article 10 of the indenture (which
relate to subordination) will require the consent of the Holders of at least
66 2/3% in principal amount of the notes then outstanding if such amendment
would adversely affect the rights of Holders of such notes. However, no
amendment may be made to the subordination provisions of the indenture that
adversely affects the rights of any holder of Senior Debt then outstanding
unless the holders of such Senior Debt (or any group or representative thereof
authorized to give a consent) consents to such change.

     Notwithstanding the foregoing, without the consent of any Holder of the
notes the Company and the Trustee may amend or supplement the indenture or the
notes to cure any ambiguity, defect or inconsistency, to provide for
uncertificated notes in addition to or in place of certificated notes, to
provide for the assumption of the Company's obligations to Holders of the notes
in the case of a merger or consolidation, to make any change that would provide
any additional rights or benefits to the Holders of the notes or that does not
adversely affect the legal rights under the indenture of any such Holder, to
secure the notes or to comply with requirements of the Commission in order to
effect or maintain the qualification of the indenture under the Trust Indenture
Act.

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

     The Company may, at its option and at any time, elect to have all of its
obligations discharged with respect to the outstanding notes ("Legal
Defeasance") except for

          (i) the rights of Holders of such outstanding notes to receive
     payments in respect of the principal of, premium, if any, or interest on
     such notes when such payments are due from the trust referred to below,

          (ii) the Company's obligations with respect to such notes concerning
     issuing temporary notes, registration of such notes, mutilated, destroyed,
     lost or stolen notes and the maintenance of an office or agency for payment
     and money for security payments held in trust,

          (iii) the rights, powers, trusts, duties and immunities of the
     Trustee, and the Company's obligations in connection therewith, and

          (iv) the Legal Defeasance provisions of the indenture.

                                        37


     In addition, the Company may, at its option and at any time, elect to have
the obligations of the Company released with respect to certain covenants that
are described in the indenture ("Covenant Defeasance") and thereafter any
omission to comply with such obligations shall not constitute a Default or Event
of Default. In the event Covenant Defeasance occurs, certain events (not
including non-payment, bankruptcy, receivership, rehabilitation and insolvency
events) described under "Events of Default and Remedies" will no longer
constitute an Event of Default.

     In order to exercise either Legal Defeasance or Covenant Defeasance,

          (i) the Company must irrevocably deposit with the Trustee, in trust,
     for the benefit of the Holders of notes, cash in U.S. dollars, non-callable
     Government Securities, or a combination thereof, in such amounts as will be
     sufficient, in the opinion of a nationally recognized firm of independent
     public accountants, to pay the principal of, premium, if any, and interest
     on the outstanding notes on the stated maturity or on the applicable
     redemption date, as the case may be, and the Company must specify whether
     the notes are being defeased to maturity or to a particular redemption
     date;

          (ii) in the case of Legal Defeasance, the Company shall have delivered
     to the Trustee an opinion of counsel in the United States reasonably
     acceptable to such Trustee confirming that

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

             (B) since the date of the indenture, there has been a change in the
        applicable federal income tax law, in either case to the effect that,
        and based thereon such opinion of counsel shall confirm that, the
        Holders of the outstanding notes will not recognize income, gain or loss
        for federal income tax purposes as a result of such Legal Defeasance and
        will be subject to federal income tax on the same amounts, in the same
        manner and at the same times as would have been the case if such Legal
        Defeasance had not occurred;

          (iii) in the case of Covenant Defeasance, the Company shall have
     delivered to the Trustee an opinion of counsel in the United States
     reasonably acceptable to such Trustee confirming that the Holders of the
     outstanding notes will not recognize income, gain or loss for federal
     income tax purposes as a result of such Covenant Defeasance and will be
     subject to federal income tax on the same amounts, in the same manner and
     at the same times as would have been the case if such Covenant Defeasance
     had not occurred;

          (iv) no Default or Event of Default shall have occurred and be
     continuing on the date of such deposit (other than a Default or Event of
     Default resulting from the borrowing of funds to be applied to such
     deposit) or insofar as Events of Default from bankruptcy or insolvency
     events are concerned, at any time in the period ending on the 91st day
     after the date of deposit;

          (v) such Legal Defeasance or Covenant Defeasance will not result in a
     breach or violation of, or constitute a default under any material
     agreement or instrument (other than the indenture) to which the Company or
     any of its Subsidiaries is a party or by which the Company or any of its
     Subsidiaries is bound;

          (vi) the Company must have delivered to the Trustee an opinion of
     counsel to the effect that after the 91st day following the deposit, the
     trust funds will not be subject to the effect of any applicable bankruptcy,
     insolvency, reorganization or similar laws affecting creditors' rights
     generally;

          (vii) the Company must deliver to the Trustee an Officers' Certificate
     stating that the deposit was not made by the Company with the intent of
     preferring the Holders of notes over the other creditors of the Company, or
     with the intent of defeating, hindering, delaying or defrauding creditors
     of the Company or others; and

          (viii) the Company must deliver to the Trustee an Officers'
     Certificate and an opinion of counsel, each stating that all conditions
     precedent provided for relating to the Legal Defeasance or the Covenant
     Defeasance have been complied with.

                                        38

GOVERNING LAW

     The indenture, the notes and the Guarantees provide that they will be
governed by the laws of the State of New York.

CERTAIN DEFINITIONS

     Set forth below are certain defined terms used in the indenture. Reference
is made to the indenture for a full definition of all such terms, as well as any
other capitalized terms used herein for which no definition is provided.

     "Acquired Debt" means, with respect to any specified Person,

          (ii) the then outstanding principal amount of such Indebtedness.

     "Wholly Owned Restricted Subsidiary" of any Person means a Restricted
Subsidiary of such Person all of the outstanding Capital Stock or other
ownership interests of which (other than directors' qualifying shares) shall at
the time be owned, directly or indirectly, by such Person or by one or more
Wholly Owned Restricted Subsidiaries of such Person.

                                        53


FORM, DENOMINATION AND REGISTRATION OF THE NOTES

     The new notes will be issued in registered form, without interest coupons,
in denominations of $1,000 and integral multiples thereof, in the form of both
global notes and certificated notes, as further provided below.

     The trustee is not required (i) to issue, register the transfer of or
exchange any note for a period of 15 days before a selection of notes to be
redeemed or repurchased, (ii) to register the transfer of or exchange any note
so selected for redemption or repurchase in whole or in part, except, in the
case of a partial redemption or repurchase, that portion of any note not being
redeemed or repurchased, or (iii) if a redemption or a repurchase is to occur
after a regular record date but on or before the corresponding interest payment
date, to register the transfer or exchange of any note on or after the regular
record date and before the date of redemption or repurchase. See "-- Global
Notes" and "-- Certificated Notes" for a description of additional transfer
restrictions applicable to the notes.

     No service charge will be imposed in connection with any transfer or
exchange of any note, but the Company may in general require payment of a sum
sufficient to cover any transfer tax or similar governmental charge payable in
connection therewith.

GLOBAL NOTES

     Global notes representing the new notes will be deposited with a custodian
for DTC, and registered in the name of a nominee of DTC. Beneficial interests in
the global notes will be shown on records maintained by DTC and its direct and
indirect participants. So long as DTC or its nominee is the registered owner or
holder of a global note, DTC or such nominee will be considered the sole owner
or holder of the notes represented by such global note for all purposes under
the indenture and the notes. No owner of a beneficial interest in a global note
will be able to transfer such interest except in accordance with DTC's
applicable procedures and the applicable procedures of its direct and indirect
participants.

     The Company will apply to DTC for acceptance of the global notes in its
book-entry settlement system. Investors may hold their beneficial interests in
the global notes directly through DTC if they are participants in DTC, or
indirectly through organizations which are participants in DTC.

     Payments of principal and interest under each global note will be made to
DTC's nominee as the registered owner of such global note. The Company expects
that the nominee, upon receipt of any such payment, will immediately credit DTC
participants' accounts with payments proportional to their respective beneficial
interests in the principal amount of the relevant global note as shown on the
records of DTC. The Company also expects that payments by DTC participants to
owners of beneficial interests will be governed by standing instructions and
customary practices, as is now the case with securities held for the accounts of
customers registered in the names of nominees for such customers. Such payments
will be the responsibility of such participants, and none of the Company, the
Trustee, the custodian or any paying agent or registrar will have any
responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial interests in any global note or for
maintaining or reviewing any records relating to such beneficial interests.

CERTIFICATED NOTES

     If DTC notifies the Company that it is unwilling or unable to continue as
depositary for a global note and a successor depositary is not appointed by the
Company within 90 days of such notice, or an Event of Default has occurred and
the trustee has received a request from DTC, the trustee will exchange each
beneficial interest in that global note for one or more certificated notes
registered in the name of the owner of such beneficial interest, as identified
by DTC. Neither the Company nor the trustee will be liable for any delay by DTC
or any participant or indirect participant in DTC in identifying the beneficial
owners of the related notes and each of those person may conclusively rely on,
and will be protected in relying on, instructions from DTC for all purposes,
including with respect to the registration and delivery, and the respective
principal amounts, of the notes to be issued.

                                        54


SAME DAY SETTLEMENT AND PAYMENT

     The indenture requires that payments in respect of the notes represented by
the global notes be made by wire transfer of immediately available funds to the
accounts specified by holders of the global notes. With respect to notes in
certificated form, the Company will make all payments by wire transfer of
immediately available funds to the accounts specified by the holders thereof or,
if no such account is specified, by mailing a check to each holder's registered
address.

     The new notes represented by the global notes are expected to trade in
DTC's Same-Day Funds Settlement System, and any permitted secondary market
trading activity in such notes will, therefore, be required by DTC to be settled
in immediately available funds. The Company expects that secondary trading in
any certificated notes will also be settled in immediately available funds.

                UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

     The following discussion is a summary of the material federal income tax
considerations relevant to the exchange of new notes for old notes but does not
purport to be a complete analysis of all potential tax effects. This discussion
is based upon the provisions of the Internal Revenue Code of 1986, as amended,
applicable Treasury Regulations promulgated and proposed thereunder, judicial
authority and administrative interpretations, as of the date hereof, all of
which are subject to change, possibly with retroactive effect or are subject to
different interpretations. This discussion does not address the tax
considerations arising under the laws of any foreign, state, local, or other
jurisdiction.

     We believe that the exchange of new notes for old notes should not be an
exchange or otherwise a taxable event to a holder for United States federal
income tax purposes. Accordingly, a holder should have the same adjusted issue
price, adjusted basis and holding period in the new notes as it had in the old
notes immediately before the exchange.

                              PLAN OF DISTRIBUTION

     Based on interpretations by the staff of the Securities and Exchange
Commission in no action letters issued to third parties, we believe that you may
transfer new notes issued in the exchange offer in exchange for the old notes
if:

     - you acquire the new notes in the ordinary course of your business; and

     - you are not engaged in, and do not intend to engage in, and have no
       arrangement or understanding with any person to participate in, a
       distribution of the new notes.

     You may not participate in the exchange offer if you are:

     - our "affiliate" within the meaning of Rule 405 under the Securities Act;
       or

     - a broker-dealer that acquired old notes directly from us.

     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 such 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
such old notes were acquired as a result of market-making activities or other
trading activities. We and the subsidiary guarantors have agreed that, starting
on the expiration date of the exchange offer and ending on the close of business
180 days after the date of such expiration date, we will make this prospectus,
as amended or supplemented, available to any broker-dealer for use in connection
with any such resale.

     If you wish to exchange new notes for your old notes in the exchange offer,
you will be required to make representations to us as described in "Exchange
Offer -- Purpose and Effect of the Exchange Offer" and "-- Procedures for
Tendering -- Your representations to us" in this prospectus and in the letter of
transmittal. In addition, if you are a broker-dealer who receives new notes for
your own account in
                                        55


exchange for old notes that were acquired by you as a result of market-making
activities or other trading activities, you will be required to acknowledge that
you will deliver a prospectus in connection with any resale by you of the new
notes.

     We will not receive any proceeds from any resale of 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 such methods of
resale, at market prices prevailing at the time of resale, at prices related to
such prevailing market prices or negotiated prices. Any such resale may be made
directly to purchasers or to or through brokers or dealers who may receive
compensation in the form of commission or concessions from any such
broker-dealer and/or the purchasers of any such new notes. Any broker-dealer
that resells 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 such new notes may be deemed to be an "underwriter" within the meaning of the
Securities Act, and any profit on any such resale of new notes and any
commission or concessions received by any such persons may be deemed to be
underwriting compensation under the Securities Act. The letter of transmittal
states that by acknowledging that it will deliver and by delivering a
prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.

     For a period of 180 days after the expiration date of the exchange offer,
we and the subsidiary guarantors will promptly send additional copies of this
prospectus and any amendment or supplement to this prospectus to any
broker-dealer that requests such documents in the letter of transmittal. We have
agreed to pay all expenses incident to the exchange offer (including the
expenses of one counsel for the holders of the old notes) other than commission
or concession of any brokers or dealers and will indemnify the holders of the
old notes (including any broker-dealers) against certain liabilities, including
liabilities under the Securities Act.

                                 LEGAL MATTERS

     The validity of the new notes offered in this exchange offer will be passed
upon for us by Vinson & Elkins L.L.P., Austin, Texas.

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

    The undersigned hereby acknowledges receipt and review of the Prospectus,
dated September 18, 2003 (the "Prospectus"), of Range Resources Corporation, a
Delaware corporation (the "Company"), and this Letter of Transmittal (the
"Letter of Transmittal"), which together describe the Company's offer to
exchange (the "Exchange Offer") its 7 3/8% Senior Subordinated Notes due 2013
(the "New Notes") that have been registered under the Securities Act of 1933, as
amended (the "Securities Act"), for a like principal amount of its issued and
outstanding 7 3/8% Senior Subordinated Notes due 2013 (the "Old Notes").
Capitalized terms used but not defined herein have the respective meaning given
to them in this Prospectus.

    The Company reserves the right, at any time or from time to time, to extend
the Exchange Offer at its discretion, in which event the term "Expiration Date"
shall mean the latest date to which the Exchange Offer is extended. The Company
shall notify the Exchange Agent and each registered holder of the Old Notes of
any extension by oral or written notice prior to 9:00 a.m., New York City time,
on the next business day after the previously scheduled Expiration Date.

    This Letter of Transmittal is to be used by holders of the Old Notes. Tender
of Old Notes is to be made according to the Automated Tender Offer Program
("ATOP") of the Depository Trust Company ("DTC") pursuant to the procedures set
forth in the Prospectus under the caption "The Exchange Offer -- Procedures for
Tendering." DTC participants that are accepting the Exchange Offer must transmit
their acceptance to DTC, which will verify the acceptance and execute a
book-entry delivery to the Exchange Agent's DTC account. DTC will then send a
computer generated message known as an "agent's message" to the exchange agent
for its acceptance. For you to validly tender your Old Notes in the Exchange
Offer, the Exchange Agent must receive prior to the Expiration Date, an agent's
message under the ATOP procedures that confirms that:

    - DTC has received your instructions to tender your Old Notes; and

    - You agree to be bound by the terms of this Letter of Transmittal.

    BY USING THE ATOP PROCEDURES TO TENDER OLD NOTES, YOU WILL NOT BE REQUIRED
TO DELIVER THIS LETTER OF TRANSMITTAL TO THE EXCHANGE AGENT. HOWEVER, YOU WILL
BE BOUND BY ITS TERMS, AND YOU WILL BE DEEMED TO HAVE MADE THE ACKNOWLEDGMENTS
AND THE REPRESENTATIONS AND WARRANTIES IT CONTAINS, JUST AS IF YOU HAD SIGNED
IT.

                                       A-1


              PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY.

and will, upon request, execute and deliver any additional documents deemed by
the Company to be necessary or desirable to complete the tender of Old Notes.

     3. The tender of the Old Notes pursuant to all of the procedures set forth
in the Prospectus will constitute an agreement between you and the Company as to

     4. The Exchange Offer is being made in reliance upon interpretations
contained in no-action letters issued to third parties by the staff of the
Securities and Exchange Commission (the "SEC"), including Exxon Capital Holdings
Corp., SEC No-Action Letter (available May 13, 1988), Morgan Stanley & Co.,
Inc., SEC No-Action Letter (available June 5, 1991) and Shearman & Sterling, SEC
No-Action Letter (available July 2, 1993), that the New Notes issued in exchange
for the Old Notes pursuant to the Exchange Offer may be offered for resale,
resold and otherwise transferred by holders thereof (other than a broker-dealer
who purchased Old Notes exchanged for such New Notes directly from the Company
to resell pursuant to Rule 144A or any other available exemption under the
Securities Act of 1933, as amended (the "Securities Act") and any such holder
that is an "affiliate" of the Company within the meaning of Rule 405 under the
Securities Act), without compliance with the registration and prospectus
delivery provisions of the Securities Act, provided that such New Notes are
acquired in the ordinary course of such holders' business and such holders are
not participating in, and have no arrangement with any person to participate in,
the distribution of such New Notes.

     5. By tendering Old Notes in the Exchange Offer, you represent and warrant
that:

          a. the New Notes acquired pursuant to the Exchange Offer are being
     acquired in the ordinary course of your business, whether or not you are
     the holder;

          b. neither you nor any such other person is engaging in or intends to
     engage in a distribution of such New Notes;

          c. neither you nor any such other person has an arrangement or
     understanding with any person to participate in the distribution (within
     the meaning of the Securities Act) of such New Notes in violation of the
     provisions of the Securities Act;

          d. neither you nor any such other person is an "affiliate," as such
     term is defined under Rule 405 promulgated under the Securities Act, of the
     Company or if you are an "affiliate," you will comply with the registration
     and prospectus delivery requirements of the Securities Act to the extent
     applicable; and

          e. the Company will acquire good and unencumbered title to the Old
     Notes upon exchange for the New Notes, free and clear of any liens,
     restrictions, charges or encumbrances and not subject to any adverse
     claims.

     6. You may, if you are unable to make all of the representations and
warranties contained in Item 5 above and as otherwise permitted in the
Registration Rights Agreement (as defined below), elect to have your Old Notes
registered in the shelf registration statement described in the Registration
Rights Agreement, dated as of July 21, 2003 (the "Registration Rights
Agreement"), by and among the Company and the Initial Purchasers (as defined
therein). Such election may be made only by notifying the Company in writing at
777 Main Street, Suite 800, Forth Worth, Texas 76102, Attention: Corporate
Secretary. By making such election, you agree, as a holder of Old Notes
participating in a shelf registration, to indemnify and hold harmless the
Company, each of the directors of the Company, each of the officers of the
Company who signs such shelf registration statement, each person who controls
the Company within the meaning of either the Securities Act or the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), and each other holder of
Old Notes, from and against any and all losses, liabilities, claims, damages and
expenses caused by any untrue statement or alleged untrue statement of a
material fact contained in any shelf registration statement or prospectus, or in
any supplement thereto or amendment thereof, or caused by the

                                       A-2


omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading; but only with respect
to information relating to the undersigned furnished in writing by or on behalf
of the undersigned expressly for use in a shelf registration statement, a
prospectus or any amendments or supplements thereto. Any such indemnification
shall be governed by the terms and subject to the conditions set forth in the
Registration Rights Agreement, including, without limitation, the provisions
regarding notice, retention of counsel, contribution and payment of expenses set
forth therein. The above summary of the indemnification provision of the
Registration Rights Agreement is not intended to be exhaustive and is qualified
in its entirety by the Registration Rights Agreement.

     7. If you are a broker-dealer that will receive New Notes for its own
account in exchange for Old Notes that were acquired as a result of
market-making activities or other trading activities, you acknowledge, by
tendering Old Notes in the Exchange Offer, that you will deliver a prospectus in
connection with any resale of such New Notes; however, by so acknowledging and
by delivering a prospectus, you will not be deemed to admit that you are an
"underwriter" within the meaning of the Securities Act. If you are a
broker-dealer and Old Notes held for your own account were not acquired as a
result of market-making or other trading activities, such Old Notes cannot be
exchanged pursuant to the Exchange Offer.

     8. Any of your obligations hereunder shall be binding upon your successors,
assigns, executors, administrators, trustees in bankruptcy and legal and
personal representatives of the undersigned.
