Forward-looking statements

This prospectus supplement and the documents incorporated by reference in this prospectus supplement and the accompanying prospectus contain “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. These statements include statements relating to our plans, strategies, objectives, expectations, intentions and adequacy of resources and are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. In general, all statements other than statements of historical fact are forward-looking statements. These forward-looking statements are based on management’s current belief, based on currently available information, as to the outcome and timing of future events. However, management’s assumptions and our future performance are subject to a wide range of business risks and uncertainties and we cannot assure you that these goals and projections can or will be met. Any number of factors could cause actual results to differ materially from those in the forward-looking statements, including, but not limited to:


•	production variance from expectations,

•	volatility of oil and natural gas prices,

•	hedging results,

•	the need to develop and replace reserves,

•	the substantial capital expenditures required to fund operations,

•	exploration risks,

•	environmental risks,

•	uncertainties about estimates of reserves,

•	competition,

•	litigation,

•	our sources of liquidity,

•	access to capital,

•	government regulation,

S-1

activities may justify revisions of estimates that were made previously. If significant, such revisions would change the schedule of any further production and development drilling. Accordingly, reserve estimates may differ from the quantities of oil and natural gas that are ultimately recovered.

Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, events, levels of activity, performance or achievements. We do not assume responsibility for the accuracy and completeness of the forward-looking statements.

Should one or more of the risks or uncertainties described in this prospectus supplement, the accompanying prospectus or the documents we incorporate by reference, or should underlying assumptions prove incorrect, our actual results and plans could differ materially from those expressed in any forward-looking statements. We undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

All forward-looking statements express or implied included in this prospectus supplement, the accompanying prospectus and the documents we incorporate by reference and attributable to Range are expressly qualified in their entirety by this cautionary statement.

This summary highlights information contained elsewhere in this prospectus supplement, the accompanying prospectus or the documents incorporated by reference. You should read carefully the entire prospectus supplement, the accompanying prospectus, the documents incorporated by reference and the other documents to which we refer for a more complete understanding of this offering. You should read “Risk Factors” beginning on page S-11 of this prospectus supplement for more information about important risks that you should consider before buying the notes to be issued in connection with this offering. Unless the context requires otherwise or as otherwise indicated, “Range,” “we,” “us,” “our” or similar terms in this prospectus supplement refer to Range Resources Corporation and its subsidiaries on a consolidated basis.

Business

We are engaged in the exploration, development and acquisition of oil and gas properties, primarily in the Southwestern, Appalachian and Gulf Coast regions of the United States. We seek to increase reserves and production through internally generated drilling projects coupled with complementary acquisitions.

At year-end 2005, our proved reserves had the following characteristics:


•	1.4 Tcfe of proved reserves;

•	80% natural gas;

•	66% proved developed;

•	78% operated;

•	a reserve life of 15.3 years (based on fourth quarter 2005 production); and

•	a pre-tax present value of $4.9 billion.

At year-end 2005, we owned 2,843,000 gross (2,381,000 net) acres of leasehold, plus over 400,000 royalty acres. We have built a multi-year inventory of drilling projects which includes over 7,700 identified drilling locations.

Range was incorporated in early 1980 under the name Lomak Petroleum, Inc. and, later that year, we completed an initial public offering and began trading on the NASDAQ. In 1996, our common stock was listed on the New York Stock Exchange. In 1998, we changed our name to Range Resources Corporation. In 1999, we implemented a strategy of internally generated drillbit growth coupled with complementary acquisitions. Our objective is to build stockholder value through consistent growth in reserves and production on a cost-efficient basis. During the past four years, we have increased our proved reserves 143%, while production has increased 59% during that same period.

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

Pending acquisition

On May 11, 2006, we entered into an agreement and plan of merger with Stroud Energy, Inc. (“Stroud”) pursuant to which a newly formed wholly-owned subsidiary of Range will merge with and into Stroud. In the merger, each holder of Stroud common stock may elect to receive

S-3

cash, shares of Range common stock or a combination thereof comprised of 50% cash and 50% Range common stock.

The acquisition will assist us in executing our business strategy by adding:


•	High quality, operated gas production and reserves, a significant portion of which is located in the Barnett Shale play, one of the largest onshore gas plays in the U.S.;

•	236 drilling locations to our inventory;

•	171 Bcfe of proved reserves and 33 Mmcfe/d in current production;

•	Incremental acreage in the Fort Worth Barnett Shale play bringing our total Barnett Shale acreage to 42,900 (gross) and 35,300 (net) acres; and

•	Highly regarded technical personnel with extensive experience in our core operating areas and in particular the Barnett Shale play.

The total consideration to be paid by Range to the shareholders of Stroud in cash and common stock is estimated at approximately $450 million, including approximately $82 million in assumed debt. The cash consideration will be paid by Range by drawing down on our Senior Credit Facility. We expect the Stroud acquisition to close in the second half of June 2006. However, the closing of the acquisition is subject to the conditions set forth in the section entitled “Risk Factors— Our pending Stroud acquisition may not close as anticipated” beginning on page S-11. We cannot assure you that the acquisition will close, and this offering is not conditioned on the closing of the acquisition.

Business strategy

Our objective is to build stockholder value through consistent growth in reserves and production on a cost-efficient basis. Our strategy is to employ internally generated drillbit growth coupled with complementary acquisitions to achieve such growth. This strategy requires us to make significant investments in technical staff, acreage and seismic to build drilling inventory. In implementing our strategy, we employ the following principal elements:


•	Concentrate in Core Operating Areas. We currently operate in three regions; the Southwestern (which includes the Permian Basin of West Texas and eastern New Mexico, the East Texas Basin, the Texas Panhandle and Anadarko Basin of Western Oklahoma), Appalachian and Gulf Coast. The pending Stroud acquisition significantly expands our Southwestern region presence in the Barnett Shale play, one of the largest onshore gas plays in the U.S. Concentrating our drilling and producing activities in these core areas allows us to develop the regional expertise needed to interpret specific geological and operating trends and develop economies of scale. Operating in multiple core areas allows us to combine the production characteristics of each area to balance our portfolio toward our goal of consistent production and reserve growth.

•	Maintain Multi-Year Drilling Inventory. We focus on areas where multiple prospective productive horizons and development opportunities exist. We use our technical expertise to build and maintain a multi-year drilling inventory. We believe that maintaining a large, multi-year inventory of drilling projects enhances our ability to consistently grow production and reserves over the next several years. Currently, we have over 7,700 identified drilling locations in inventory. In 2005, we drilled 841 gross (594 net) wells. In 2006, our capital program targets the drilling of 1,065 gross (789 net) wells.

S-4


•	Make Complementary Acquisitions. We target complementary acquisitions in existing core areas and focus on acquisition candidates where our existing scientific knowledge is transferable and drilling results can be forecast with confidence. Over the past three years, we have completed $743.0 million of complementary acquisitions (excluding our pending Stroud acquisition) located in the Southwestern and Appalachian regions.

•	Manage Our Risk Exposure. We allocate the majority of our capital spending to long-term development projects in areas where multiple productive horizons exist to reduce our risk exposure. Where our exploration projects may involve high dry hole costs, we often bring in industry partners in order to reduce financial exposure. We try to limit our exploratory expenditures to 20% of our annual capital budget per year. Most of our exploratory drilling projects are structural reservoir projects where we have several years of experience in drilling such projects. We also invest in new seismic data and technology each year. By equipping our geologists and geophysicists with state-of-the-art seismic technology with multiple reprocessing applications, we hope to multiply the number of higher potential exploration prospects we drill without substantially adding to dry hole risk.

•	Maintain Flexibility. Given the volatility of commodity prices and the risks involved in drilling, we remain flexible and may adjust our capital budget throughout the year. We may defer capital projects in order to seize an attractive acquisition opportunity. If certain areas generate higher than anticipated returns, we may accelerate drilling in those areas and decrease capital expenditures elsewhere. We also believe in maintaining a strong balance sheet and using commodity hedging. This will allow us to be more opportunistic in cyclical price environments as well as provide more consistent financial results.

Risk factors

You should carefully consider and evaluate all the information included or incorporated by reference in this prospectus supplement and the accompanying prospectus, including the risks described below, before you decide to buy our notes. Our business, financial condition and results of operations could be materially adversely affected by any of these risks. The trading price of the 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 supplement and 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 supplement and the accompanying 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 supplement and the accompanying prospectus.

Risks related to our business

Volatility of oil and natural gas prices significantly affects our cash flow and capital resources and could hamper our ability to produce oil and gas economically

Oil and natural gas prices are volatile, and an extended decline in prices would adversely affect our profitability and financial condition. The oil and natural gas industry is typically cyclical, and prices for oil and natural gas have been highly 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 declined, which contributed to the substantial losses we reported in those years. By early 2001, oil and natural gas prices reached levels above historical norms. Prices declined in the second half of 2001 but have risen steadily since mid-2002. Recent oil and natural gas prices are at historic highs, with oil prices recently reaching $75.35 per barrel and natural gas prices reaching $15.78 per mcf in some markets. Higher oil and natural gas prices have contributed to our positive earnings over the last several years. However, long-term supply and demand for oil and natural gas is uncertain and subject to a myriad of factors including technology, geopolitics, weather patterns and economics.

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 will 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 with respect to a significant portion of our future production. The goal of these hedges is to lock in prices so as to limit volatility and increase the predictability of cash flow. These transactions limit our potential gains if oil and natural gas prices rise above the price established by the hedge. For

S-11

example, at December 31, 2005, we were party to swap hedging arrangements covering 6.7 Bcf and 0.1 million barrels of oil. We also had collars covering 82.8 Bcf of gas and 4.8 million barrels of oil. The derivatives’ fair value was a pre-tax loss of $231.0 million. At March 31, 2006, the derivatives’ fair value was a pre-tax loss of $134.9 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 or the relationship between the hedged price index and the oil and gas sales price.

Recently, due to the trading volatility of NYMEX gas contracts, we have experienced larger than usual differentials between actual prices paid at delivery points and NYMEX based gas hedges. Due to this event, certain of our gas hedges no longer qualified for hedge accounting in the fourth quarter and were marked-to-market as a gain of $10.9 million. This may result in more volatility in our income in future periods. In the three months ended March 31, 2006, we recorded a marked-to-market gain of $11.3 million relating to these gas hedges.

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 reserves, which comprise a significant portion of our reserves, are by their nature uncertain. Although we believe these estimates are reasonable, actual production, revenues and costs to develop will likely vary from estimates, and these variances could be material.

The accuracy of any reserve 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 and value of the reserves.

If oil and natural gas prices decrease or exploration efforts are unsuccessful, we may be required to take write-downs of our oil and natural gas properties

In the past, we have been required to write down the carrying value of certain of our oil and natural gas properties, and there is a risk that we will be required to take additional write-downs in the future. This could occur when oil and natural gas prices are low, or if we have downward adjustments to our estimated proved reserves, increases in our estimates of operating or development costs, deterioration in our exploration results or mechanical problems with wells where the cost to redrill or repair does not justify the expense which might occur due to hurricanes.

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 net cash flows

S-12

from that property and on acreage when conditions indicate the carrying value is not recoverable. 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 drilling results, production data, economics and other factors. While an impairment charge reflects our long-term ability to recover an investment, it does not impact cash or cash flow from operating activities, but it does reduce our reported 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 recorded an impairment of $31.1 million due to lower year-end prices. At year-end 2004, we recorded an impairment of $3.6 million on an offshore property due to hurricane damage and related production declines. As of May 9, 2006, we continued to have 1.5 Mmcfe per day of production shut-in due to the effects of hurricanes Katrina and Rita. While we do not currently believe there is any material long-term damage to the shut-in properties, we cannot yet predict whether impairment charges may be required due to these storms.

The demand for field services and their ability to meet that demand may limit our ability to drill and produce our oil and natural gas properties

Due to current industry demands, well service providers and related equipment and personnel are in short supply. This is causing escalating prices, the possibility of poor services coupled with potential damage to downhole reservoirs and personnel injuries. Such pressures will likely increase the actual cost of services, extend the time to secure such services and add costs for damages due to accidents sustained from the over use of equipment and inexperienced personnel.

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 natural 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; or

•	Suspension of operations.

As we begin drilling to deeper horizons and in more geologically complex areas, we could experience a greater increase in operating and financial risks due to inherent higher reservoir pressures and unknown downhole risk exposures. As we continue to drill deeper, the number of rigs capable of drilling to such depths will be fewer and we may experience greater competition from other operators.

S-13

Our 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 from 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. Currently, we expect substantial increases in premiums especially in the areas affected by the hurricanes and tropical storms. In addition, we expect insurers to impose revised limits affecting how much the insurers will pay on actual storm claims plus the cost to re-drill wells where substantial damage has been incurred. Insurers are also requiring us to retain larger deductibles and reducing the scope of what insurable losses will include. Even with the increase in future insurance premiums, coverage will be reduced, requiring us to bear a greater potential risk if our oil and gas properties are damaged. We do not maintain any business interruption insurance. 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, terms of 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 acquisition opportunities and place us at a competitive disadvantage. For example, at March 31, 2006, approximately 64% of our debt was at fixed interest rates with the remaining 36% subject to variable interest rates.

Some of our current and potential competitors have greater resources than we have and we may not be able to successfully compete in acquiring, exploring and developing new properties

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.

S-14

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.

Acquisitions are subject to the risks and uncertainties of evaluating reserves and potential liabilities and may be disruptive and difficult to integrate into our business

We could be subject to significant liabilities related to our acquisitions. 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 in all of the properties, 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.

For example, in 1997, we consummated a large acquisition that proved extremely disappointing. Production from the acquired properties fell more rapidly than anticipated and further development results were below the results we had originally projected. The poor production performance of these properties resulted in material downward reserve revisions. There is no assurance that our recent and/or future acquisition activity will not result in similarly disappointing results.

In addition, there is intense competition for acquisition opportunities in our industry. Competition for acquisitions may increase the cost of, or cause us to refrain from, completing acquisitions. Our acquisition strategy is dependent upon, among other things, our ability to obtain debt and equity financing and, in some cases, regulatory approvals. Our ability to pursue our acquisition strategy may be hindered if we are not able to obtain financing on terms acceptable to us or regulatory approvals.

Acquisitions often pose integration risks and difficulties. In connection with recent and future acquisitions, the process of integrating acquired operations into our existing operations may result in unforeseen operating difficulties and may require significant management attention and financial resources that would otherwise be available for the ongoing development or expansion of existing operations. Future acquisitions could result in our incurring additional debt, contingent liabilities, expenses and diversion of resources, all of which could have a material adverse effect on our financial condition and operating results.

Our success depends on key members of our management and our ability to attract and retain experienced technical and other professional personnel

Our success is highly dependent on our management personnel, none of which is 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 technical and other professional personnel 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 economically find or

S-15

acquire and produce additional oil and natural gas reserves. 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 as reserves are produced. Future oil and natural gas production, therefore, is 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 or acquire and develop 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 of May 9, 2006, we continued to have 1.5 Mmcfe per day of production shut-in due to the effects of hurricanes Katrina and Rita. As a result, we could incur substantial expense and liabilities that could materially reduce the funds available for exploration, development or leasehold acquisitions or result in the 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. 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 expenditures 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. One or more of the technologies that we currently use or that we may implement in the future may become obsolete. 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. If we are not able to maintain technological advancements consistent with industry standards, our operations and financial condition may be adversely affected.

Our business depends on oil and natural gas transportation facilities, many 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. We generally do not purchase firm transportation on third party facilities and therefore, our production transportation can be interrupted by those having firm arrangements. Federal and state regulation of oil and natural

S-16

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.

The disruption of third-party facilities due to maintenance and/or weather could negatively impact our ability to market and deliver our products. We have no control over when or if such facilities are restored or what prices will be charged. A total shut-in of production could materially affect us due to a lack of cash flow, and if a substantial portion of the production is hedged at lower than market prices, those financial hedges would have to be paid from borrowings absent sufficient cash flow.

We exist in a litigious environment

Any constituent could bring suit or allege a violation of an existing contract. This action could delay when operations can actually commence or could cause a halt to production until such alleged violations are resolved by the courts. Not only could we incur significant legal and support expenses in defending our rights, planned operations could be delayed which would impact our future operations and financial condition. Such legal disputes could also distract management and other personnel from their primary responsibilities.

Our financial statements are complex

Due to accounting rules, our financial statements continue to be complex, particularly with reference to hedging, asset retirement obligations, equity awards and the accounting for our deferred compensation plan. We expect such complexity to continue and possibly increase.

Our pending Stroud acquisition may not close as anticipated resulting in material effects on our business

We expect that our pending acquisition of Stroud will close in the second half of June 2006. However, this offering is not conditioned on the closing of the Stroud acquisition, which may not ultimately close. The closing of the Stroud acquisition is subject to certain closing conditions, including, without limitation:


•	the shareholders of Stroud shall have approved the merger;

•	the representations and warranties of both us and Stroud are true and correct in all material respects as of the closing date and both parties shall have complied, in all material respects, with all covenants in the merger agreement;

•	there shall not have occurred a material adverse effect on us or Stroud as defined in the merger agreement;

•	there shall be no legal proceeding instituted to stop the closing of the acquisition; and

•	certain necessary third party consents shall have been obtained.

We cannot predict the impact on our stock price or the market value of the notes, if the acquisition does not close.

S-17

Risks related to investment in the notes

Our significant indebtedness could limit our ability to successfully operate our business

We are leveraged and our exploration and development program will require substantial capital resources estimated to range from $450 to $550 million per year over the next three years, depending on the level of drilling and the expected cost of services. Our existing operations will also require ongoing capital expenditures. In addition, if we decide to pursue additional acquisitions, our capital expenditures will increase both to complete such acquisitions and to explore and develop any newly acquired properties.

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


•	We may be required to dedicate a substantial portion of our cash flows from operations to the payment of our indebtedness, reducing the funds available 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 general economy;

•	The terms of our existing credit arrangements 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.

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 and our existing indebtedness do not prohibit us from issuing additional notes or other indebtedness provided that certain financial ratios are satisfied. As of March 31, 2006, our Senior Credit Facility permitted borrowings of $600 million (of which $246.1 million was outstanding), all of which would be senior to the notes. We will use the net proceeds of this offering to pay down a portion of the outstanding balance of our Senior Credit Facility. However, the terms of our Senior Credit Facility do not prohibit us from re-borrowing any amounts which we have repaid. 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 results 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 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

S-18

insufficient for payment of interest on and principal of our debt in the future, including payments on the 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 these 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 notes

Holders of our senior indebtedness will have claims that are prior to your claims as holders of the 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 notes will participate ratably with all holders of our senior subordinated indebtedness that is deemed to be of the same class as the 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 notes. As a result, holders of notes may receive less, ratably, than holders of senior indebtedness.

As of March 31, 2006, we had total Senior Debt of approximately $246.1 million. Any additional indebtedness we are permitted to incur under the Indenture or the indentures may be senior to the notes.

In addition, we conduct substantially all of our operations through our subsidiaries and some of our subsidiaries do not guarantee the 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 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 notes.

We may not be able to repurchase the notes

Under the terms of the Indenture, you may require us to repurchase all or a portion of your 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 (in which case, we could be required to issue common stock to pay the repurchase price). Our existing and any future credit agreements or other debt agreements to which we become a party may provide that our obligation to purchase or redeem the notes would be an event of default under such agreement. As a result, we may be restricted or prohibited from repurchasing or redeeming the notes. If we are prohibited from repurchasing or redeeming the notes, we could seek the consent of our then- existing lenders to repurchase or redeem the 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 or redeem the notes. Our failure to redeem tendered notes would constitute a default under the Indenture and might constitute a default under the terms of other indebtedness that we incur.

S-19

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 notes upon a change in control would not necessarily afford holders of notes protection in the event of a highly leveraged transaction, reorganization, merger or similar transaction involving us.

The notes may receive a lower rating than anticipated

If one or more rating agencies assigns the notes a rating lower than the rating expected by investors, or reduces their rating in the future, the market price of the notes would be adversely affected.

There is no public trading market for the notes

The notes will constitute a new issue of securities for which there is no established trading market. We do not intend to list the notes on any national securities exchange or seek the admission of the notes for quotation through the National Association of Securities Dealers Automated Quotation System. We have been informed by the underwriters that they intend to make a market in the notes after this offering is completed. However, the underwriters are not obligated to do so and may cease their market-making activities at any time. In addition, the liquidity of the trading market in the notes, and the market price quoted for the notes, may be adversely affected by changes in the overall market for high yield securities and by changes in our financial performance or prospects or in the financial performance or prospects of companies in our industry generally. As a result, we cannot assure you that an active trading market will develop or be maintained for the notes. If an active market does not develop or is not maintained, the market price and liquidity of the notes may be adversely affected.

Federal and state fraudulent transfer laws may permit a court to void the notes and the guarantees and, if that occurs, you may not receive any payments on the notes

The issuance of the notes and the guarantees may be subject to review under federal and state fraudulent transfer and conveyance statutes. While the relevant laws may vary from state to state, under such laws the payment of consideration will be a fraudulent conveyance if (1) we paid the consideration with the intent of hindering, delaying or defrauding creditors or (2) we or any of our subsidiary guarantors, as applicable, received less than reasonably equivalent value or fair consideration in return for issuing either the notes or a guarantee and, in the case of (2) only, one of the following is also true:


•	we or any of our subsidiary guarantors were or was insolvent or rendered insolvent by reason of the incurrence of the indebtedness;

•	payment of the consideration left us or any of our subsidiary guarantors with an unreasonably small amount of capital to carry on the business; or

•	we or any of our subsidiary guarantors intended to, or believed that we or it would, incur debts beyond our or its ability to pay as they mature.

If a court were to find that the issuance of the notes or a guarantee was a fraudulent conveyance, the court could void the payment obligations under the notes or such guarantee or subordinate the notes or such guarantee to presently existing and future indebtedness of ours or such guarantor, or require the holders of the notes to repay any amounts received with respect to the notes or such guarantee. In the event of a finding that a fraudulent conveyance

S-20

occurred, you may not receive any repayment on the notes. Further, the voidance of the notes could result in an event of default with respect to our other debt and that of our subsidiaries that could result in acceleration of such debt.

Generally, an entity would be considered insolvent if at the time it incurred indebtedness:


•	the sum of its debts, including contingent liabilities, was greater than the fair saleable value of all its assets;

•	the present fair saleable value of its assets were less than the amount that would be required to pay its probable liability on its existing debts and liabilities, including contingent liabilities, as they become absolute and mature; or

•	it could not pay its debts as they become due.

We cannot be certain as to the standards a court would use to determine whether or not we or the subsidiary guarantors were solvent at the relevant time, or regardless of the standard that a court uses, that the issuance of the notes and the guarantees would not be subordinated to our or any guarantor’s other debt.

If the guarantees were legally challenged, any guarantee could also be subject to the claim that, since the guarantee was incurred for our benefit, and only indirectly for the benefit of the guarantor, the obligations of the applicable guarantor were incurred for less than fair consideration. A court could thus void the obligations under the guarantees, subordinate them to the applicable guarantor’s other debt or take other action detrimental to the holders of the notes.

The market price of the notes may fluctuate significantly, which may result in losses for investors

The market price of the notes could be volatile. We expect the market price of the notes to be subject to fluctuations as a result of a variety of factors, including factors beyond our control. These include:


•	changes in oil and natural gas prices;

•	variations in quarterly drilling, recompletions, acquisitions and operating results;

•	changes in financial estimates by securities analysts;

•	changes in market valuations of comparable companies;

•	additions or departures of key personnel; and

•	future incurrence of more debt.

We may fail to meet expectations of the market or of securities analysts at some time in the future, and the market price of the notes could decline as a result.

S-21

Use of proceeds

We estimate that the net proceeds from this offering (after deducting discounts to the underwriters and estimated expenses of the offering) will be approximately $195.5 million. We intend to use the net proceeds from this offering to pay down a portion of the outstanding balance on our Senior Credit Facility, which was $246.1 million as of March 31, 2006.

Description of other indebtedness

Senior credit facility

In June 2004, we entered into an amended and restated $600.0 million revolving bank facility, which is secured by substantially all of our assets. The bank credit facility provides for a borrowing base subject to redeterminations semi-annually each April and October and pursuant to certain unscheduled redeterminations. At March 31, 2006, the borrowing base was $600.0 million. At March 31, 2006, the outstanding balance under the bank credit facility was $246.1 million and there was $353.9 million of borrowing capacity available. In April 2006, the loan maturity was extended two years to January 1, 2011 and the borrowing base was redetermined at $600.0 million. Borrowing under the bank credit facility can either be base rate loans or LIBOR loans. On all base rate loans, the rate per annum is equal to the lesser of (i) the maximum rate (the “weekly ceiling” as defined in Section 303 of the Texas Finance Code or other applicable laws if greater) (the “Maximum Rate”) or, (ii) the sum of (A) the higher of (1) the prime rate for such date, or (2) the sum of the federal funds effective rate for such data plus one-half of one percent (0.50%) per annum, plus a base rate margin of between 0.0% to 0.5% per annum depending on the total outstanding under the bank credit facility relative to the borrowing base. On all LIBOR loans, we pay a varying rate per annum equal to the lesser of (i) the Maximum Rate, or (ii) the sum of the quotient of (A) the LIBOR base rate, divided by (B) one minus the reserve requirement applicable to such interest period, plus a LIBOR margin of between 1.0% and 1.75% per annum depending on the total outstanding under the bank credit facility relative to the borrowing base. We may elect, from time-to-time, to convert all or any part of our LIBOR loans to base rate loans or to convert all or any part of the base rate loans to LIBOR loans. The weighted average interest rate on the bank credit facility was 5.6% and 4.1% for the three months ended March 31, 2006 and 2005, respectively. A commitment fee is paid on the undrawn balance based on an annual rate of between 0.25% and 0.50%. At March 31, 2006, the commitment fee was 0.25% and the interest rate margin was 1.0%. At April 24, 2006, the interest rate (including applicable margin) was 5.9%.

7³/8% senior subordinated notes due 2013

In 2003, we issued $100.0 million of 7³/8% senior subordinated notes due 2013, or the 7³/8% Notes. In 2004, we issued an additional $100.0 million of 7³/8% Notes; therefore, $200.0 million of the 7³/8% Notes are currently outstanding. We pay interest on the 7³/8% Notes semi-annually in January and July of each year. The 7³/8% Notes mature in 2013 and are guaranteed by certain of our subsidiaries. The 7³/8% Notes were issued at a discount which is amortized into interest expense over the life of the 7³/8 % Notes.

We may redeem the 7³/8% Notes, in whole or in part, at any time on or after July 15, 2008, at redemption prices from 103.7% of the principal amount as of July 15, 2008, and declining to 100.0% on July 15, 2011 and thereafter. Prior to July 15, 2006, we may redeem up to 35% of the original aggregate principal amount of the notes at a redemption price of 107.4% of the principal amount thereof plus accrued and unpaid interest, if any, with the proceeds of certain equity offerings. If we experience a change of control, there may be a requirement to repurchase all or a portion of the 7³/8% Notes at 101% of the principal amount plus accrued and unpaid interest, if any. The 7³/8% Notes and the guarantees by our subsidiary guarantors are general, unsecured obligations and are subordinated to our senior debt and will be subordinated to future senior debt that Range and our subsidiary guarantors are permitted to incur under the bank credit facility and the indenture governing the 7³/8 % Notes.

6³/8% senior subordinated notes Due 2015

In 2005, we issued $150.0 million of 6³/8% Senior Subordinated Notes due 2015, or the 6³/8% Notes. We pay interest on the 6³/8% Notes semi-annually in March and September of each year. The 6³/8 % Notes mature in 2015 and are guaranteed by certain of our subsidiaries.

We may redeem the 6³/8% Notes, in whole or in part, at any time on or after March 15, 2010, at redemption prices from 103.2% of the principal amount as of March 15, 2010 and declining to 100% on March 15, 2013 and thereafter. Prior to March 15, 2008, we may redeem up to 35% of the original aggregate principal amount of the notes at a redemption price of 106.4% of the principal amount thereof plus accrued and unpaid interest, if any, with the proceeds of certain equity offerings. If we experience a change of control, there may be a requirement to repurchase all or a portion of the 6³/8% Notes at 101% of the principal amount plus accrued and unpaid interest, if any. The 6³/8% Notes and the guarantees by our subsidiary guarantors are general, unsecured obligations and are subordinated to our bank debt and will be subordinated to future senior debt that Range and our subsidiary guarantors are permitted to incur under the bank credit facility and the indenture governing the 6³/8 % Notes.

Description of notes

The Company will issue the notes as an issue of securities under the indenture described more fully in the accompanying prospectus under the heading “Description of Debt Securities,” as supplemented by a supplemental indenture or board resolution dated as of the date the notes are first issued (together, the “indenture”). This Description of the Notes, together with the “Description of Debt Securities” included in the accompanying base prospectus, is intended to be an overview of the material provisions of the notes and the indenture and it supplements the description of the general terms and provisions of the securities set forth in the accompanying prospectus. Since this Description of Notes and the Description of Debt Securities is only a summary, you should refer to the indenture for a complete description of our obligations and your rights. You will find the definitions of certain capitalized terms used in this description under the heading “Description of Debt Securities— Certain definitions” in the accompanying prospectus. Other capitalized terms have the meanings assigned to them elsewhere in this description or in the indenture. For purposes of this description, references to “the Company,” “Range”, “we,” “our” and “us” refer only to Range Resources Corporation and any successor obligor on the notes, and not to any of its subsidiaries.

General

The notes. The notes


•	will be general unsecured, senior obligations of the Company;

S-26

Optional redemption

Except as otherwise described below, the notes will not be redeemable at the Company’s option prior to , 2011. 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 of the years indicated below:



Year	% of principal amount

2011		%
2012		%
2013		%
2014 and thereafter		100.000%

Prior to , 2009, 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 % 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.

In addition, before , 2011, the Company may redeem all or, from time to time, any part of the notes upon not less than 30 nor more than 60 days’ notice, at a redemption price equal to 100% of the principal amount thereof plus the Make-Whole Premium plus accrued and unpaid interest, if any, to the redemption date (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date).

“Make-Whole Premium” means, with respect to a note at any redemption date, the excess of (A) the present value at such time of (1) the redemption price, excluding accrued interest, of such note at , 2011, (as set forth in the table above) plus (2) all required interest payments, excluding accrued interest, due on such note through , 2011, computed using a discount rate equal to the Treasury Rate plus 50 basis points, over (B) the principal amount of such note.

“Treasury Rate” means the yield to maturity at the time of computation of United States Treasury securities with a constant maturity (as compiled and published in the most recent Federal Reserve Statistical Release H.15 (519) which has become publicly available at least two business days prior to the redemption date (or, if such Statistical Release is no longer published, any publicly available source or similar market data)) most nearly equal to the period from the redemption date to , 2011; provided, however, that if the period from the redemption date to , 2011 is not equal to the constant maturity of a United States Treasury security for which a weekly average yield is given, the Treasury Rate shall be obtained by linear interpolation (calculated to the nearest one-twelfth of a year) from the weekly average yields of United States Treasury securities for which such yields are given, except that if the period from the redemption date to , 2011 is less than one year, the weekly average yield on actually traded United States Treasury securities adjusted to a constant maturity of one year shall be used.

S-27

If the optional redemption date is on or after an interest record date and on or before the related interest payment date, the accrued and unpaid interest, if any, will be paid to the person in whose name the note is registered at the close of business, on such record date, and no additional interest will be payable to holders whose notes will be subject to redemption by the Company.

S-28

United States federal income tax considerations

The following discussion summarizes the material United States federal income tax considerations relevant to the acquisition, ownership and disposition of the notes by an initial beneficial owner of the notes. This discussion is based upon the provisions of the Internal Revenue Code of 1986, as amended (the “Code”), applicable Treasury Regulations promulgated 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. We cannot assure you that the Internal Revenue Service (the “IRS”) will not challenge one or more of the tax consequences described herein, and we have not obtained, nor do we intend to obtain, a ruling from the IRS or an opinion of counsel with respect to the United States federal tax consequences of acquiring, holding or disposing of the notes.

In this discussion, we do not purport to address all tax considerations that may be important to a particular holder in light of the holder’s circumstances, or to certain categories of investors that may be subject to special rules, such as financial institutions, insurance companies, regulated investment companies, tax-exempt organizations, dealers in securities or currencies, U.S. holders (as defined below) whose functional currency is not the U.S. dollar, U.S. expatriates, persons subject to the alternative minimum tax, or persons who hold the notes as part of a hedge, conversion transaction, straddle or other risk reduction transaction. This discussion is limited to initial holders who purchase the notes for cash at the issue price, which will equal the first price to the public (not including bond houses, brokers or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers) at which a substantial amount of the notes is sold for money and who hold the notes as capital assets (within the meaning of section 1221 of the Code). If a partnership holds the notes, the tax treatment of a partner generally will depend upon the status of the partner and the activities of the partnership. If you are a partner or a partnership acquiring the notes, you should consult your own tax advisor about the U.S. federal income tax consequences of acquiring, holding and disposing of the notes. This discussion also does not address the tax considerations arising under the laws of any foreign, state, local or other jurisdiction.

Investors considering the purchase of notes should consult their own tax advisors regarding the application of the U.S. federal income tax laws to their particular situations and the applicability and effect of state, local or foreign tax laws and tax treaties.

Consequences to U.S. holders

You are a “U.S. holder” for purposes of this discussion if you are a beneficial owner of a note and you are for U.S. federal income tax purposes:


•	an individual who is a U.S. citizen or U.S. resident alien;

•	a corporation, or other entity taxable as a corporation for U.S. federal income tax purposes, that was created or organized in or under the laws of the United States, any state thereof or the District of Columbia;

•	an estate whose income is subject to U.S. federal income taxation regardless of its source; or

•	a trust if a court within the United States is able to exercise primary supervision over the administration of the trust and one or more United States persons have the authority to control all substantial decisions of the trust, or that has a valid election in effect under applicable U.S. Treasury Regulations to be treated as a United States person.

S-29

Interest on the notes

The notes will be issued without original issue discount for United States federal income tax purposes. Accordingly, you will generally be required to recognize as ordinary income any interest paid or accrued on the notes, in accordance with your regular method of accounting for federal income tax purposes.

Disposition of the notes

You will generally recognize capital gain or loss on the sale, redemption, exchange, retirement or other taxable disposition of a note. This gain or loss will equal the difference between your adjusted tax basis in the note and the proceeds you receive, excluding any proceeds attributable to accrued interest which will be recognized as ordinary interest income to the extent you have not previously included the accrued interest in income. The proceeds you receive will include the amount of any cash and the fair market value of any other property received for the note. Your adjusted tax basis in the note will generally equal the amount you paid for the note less any principal payments received. The gain or loss will be long-term capital gain or loss if you held the note for more than one year. Long- term capital gains of individuals, estates and trusts currently are taxed at a maximum rate of 15%. The deductibility of capital losses may be subject to limitation.

Information reporting and backup withholding

Information reporting will apply to payments of interest and principal on, or the proceeds of the sale or other disposition of, notes held by you, and backup withholding (currently at a rate of 28%) will apply unless you provide the appropriate intermediary with a taxpayer identification number, certified under penalties of perjury, as well as certain other information or otherwise establish an exemption from backup withholding. Any amount withheld under the backup withholding rules is allowable as a credit against your U.S. federal income tax liability, if any, and a refund may be obtained if the amounts withheld exceed your actual U.S. federal income tax liability and you provide the required information or appropriate claim form to the IRS.

Consequences to non-U.S. holders

You are a “non-U.S. holder” for purposes of this discussion if you are a beneficial owner of notes and you are not a U.S. holder.

Interest on the notes

If you are a non-U.S. holder, payments of interest on the notes generally will be exempt from withholding of U.S. federal income tax under the “portfolio interest” exemption if you properly certify as to your foreign status as described below, and:


•	you do not own, actually or constructively, 10% or more of the total combined voting power of all classes of our stock entitled to vote; and

•	you are not a “controlled foreign corporation” that is directly or indirectly related to us.

The portfolio interest exemption and several of the special rules for non-U.S. holders described below generally apply only if you appropriately certify as to your foreign status. You can generally meet this certification requirement by providing a properly executed IRS Form W-8BEN or appropriate substitute form to us or our paying agent. If you hold the notes through

S-30

a financial institution or other agent acting on your behalf, you may be required to provide appropriate certifications to the agent. Your agent will then generally be required to provide appropriate certifications to us or our paying agent, either directly or through other intermediaries. Special rules apply to foreign partnerships, estates and trusts, and in certain circumstances certifications as to foreign status of partners, trust owners or beneficiaries may have to be provided to us or our paying agent. In addition, special rules apply to qualified intermediaries that enter into withholding agreements with the IRS.

If you cannot satisfy the requirements described above, payments of interest made to you will be subject to the 30% U.S. federal withholding tax, unless you provide us with a properly executed IRS Form W-8BEN or appropriate substitute form claiming an exemption from (or a reduction of) withholding under the benefit of a tax treaty, or the payments of interest are effectively connected with your conduct of a trade or business in the United States and you meet the certification requirements described below. See “—Income or Gain Effectively Connected With a U.S. Trade or Business.”

Disposition of notes

You generally will not be subject to U.S. federal income tax on any gain realized on the sale, redemption, exchange, retirement or other taxable disposition of a note unless:


•	the gain is effectively connected with the conduct by you of a U.S. trade or business (and where an applicable tax treaty applies, attributable to your permanent establishment in the United States); or

•	you are an individual who has been present in the United States for 183 days or more in the taxable year of disposition and certain other requirements are met.

Income or gain effectively connected with a U.S. trade or business

The preceding discussion of the tax consequences of the purchase, ownership and disposition of notes by you generally assumes that you are not engaged in a U.S. trade or business. If any interest on the notes or gain from the sale, exchange or other taxable disposition of the notes is effectively connected with a U.S. trade or business conducted by you, (and where an applicable treaty applies, attributable to your permanent establishment in the United States) then the income or gain will be subject to U.S. federal income tax at regular graduated income tax rates, but will not be subject to withholding tax if certain certification requirements are satisfied. You can generally meet the certification requirements by providing a properly executed IRS Form W-8ECI or appropriate substitute form to us, or our paying agent. If you are eligible for the benefits of a tax treaty between the United States and your country of residence, any “effectively connected” income or gain will generally be subject to U.S. federal income tax only if it is also attributable to a permanent establishment maintained by you in the United States. If you are a corporation, that portion of your earnings and profits that is effectively connected with your U.S. trade or business (or where an applicable tax treaty applies, attributable to your permanent establishment in the United States) also may be subject to a “branch profits tax” at a 30% rate, although an applicable tax treaty may provide for a lower rate.

U.S. federal estate tax

Individual non-U.S. holders and entities the property of which is potentially includible in such an individual’s gross estate for U.S. federal estate tax purposes (for example, a trust funded by

S-31

such an individual and with respect to which the individual has retained certain interests or powers), should note that, absent an applicable treaty benefit, a note or coupon will be treated as U.S. situs property subject to U.S. federal estate tax if payments on the note, if received by the decedent at the time of death, would have been:


•	subject to U.S. federal withholding tax (even if the W-8BEN certification requirement described above were satisfied); or

•	effectively connected with the conduct by the holder of a trade or business in the United States.

Information reporting and backup withholding

Payments to non-U.S. holders of interest on a note, and amounts withheld from such payments, if any, generally will be required to be reported to the IRS and to you.

United States backup withholding generally will not apply to payments of interest and principal on a note to a non-U.S. holder if the statement described in “Consequences to Non-U.S. Holders— Interest on the Notes” is duly provided by the holder or the holder otherwise establishes an exemption, provided that we do not have actual knowledge or reason to know that the holder is a United States person.

Payment of the proceeds of a sale of a note effected by the U.S. office of a U.S. or foreign broker will be subject to information reporting requirements and backup withholding unless you properly certify under penalties of perjury as to your foreign status and certain other conditions are met or you otherwise establish an exemption. Information reporting requirements and backup withholding generally will not apply to any payment of the proceeds of the sale of a note effected outside the United States by a foreign office of a broker. However, unless such a broker has documentary evidence in its records that you are a non-U.S. holder and certain other conditions are met, or you otherwise establish an exemption, information reporting will apply to a payment of the proceeds of the sale of a note effected outside the United States by such a broker if the broker:


•	is a United States person;

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

•	is a controlled foreign corporation for U.S. federal income tax purposes; or

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

Any amount withheld under the backup withholding rules may be credited against your U.S. federal income tax liability and any excess may be refundable if the proper information is provided to the IRS.

The preceding discussion of certain U.S. federal income tax considerations is for general information only and is not tax advice. Each prospective investor should consult its own tax advisor regarding the particular federal, state, local and foreign tax consequences of purchasing, holding, and disposing of our notes, including the consequences of any proposed change in applicable laws.

S-32

Underwriting

Subject to the terms and conditions set forth in the underwriting agreement among Range and the underwriters, we have agreed to sell to each underwriter, and each underwriter has severally agreed to purchase from us, the principal amount of the notes that appears opposite its name in the table below:



Underwriter	Principal amount of notes

J.P. Morgan Securities Inc.	$
Credit Suisse Securities (USA) LLC
Banc of America Securities LLC
Harris Nesbitt Corp.
Wachovia Capital Markets, LLC
Calyon Securities (USA) Inc.
Comerica Securities, Inc.
Fortis Securities LLC
Capital One Southcoast, Inc.
Keybanc Capital Markets
Scotia Capital (USA) Inc.
Natexis Bleichroeder Inc.

Total	$	200,000,000

The obligations of the underwriters under the underwriting agreement, including their agreement to purchase notes from us, are several and not joint. Those obligations are also subject to various conditions in the underwriting agreement being satisfied. The underwriters have agreed to purchase all of the notes if any of them are purchased.

The underwriters initially propose to offer the notes to the public at the public offering price that appears on the cover of this prospectus supplement. The underwriters may offer the notes to selected dealers at the public offering price minus a concession of up to 0.50% of the principal amount. In addition, the underwriters may allow, and those selected dealers may reallow, a concession of up to 0.25% of the principal amount to certain other dealers. After the initial offering, the underwriters may change the public offering price and any other selling terms.

In the underwriting agreement, we have agreed that:


	•	We will not offer or sell any of our debt securities having a term of more than one year (other than the notes) for a period of 90 days after the date of this prospectus supplement without the prior consent of J.P. Morgan Securities Inc.

	•	We will pay our own expenses related to the offering, which we estimate will be $500,000.

	•	We will indemnify the underwriters against certain liabilities, including liabilities under the Securities act of 1933, or contribute payments that the underwriters may be required to make in respect of those liabilities.

The notes are new issues of securities with no established trading market. We do not intend to apply for the notes to be listed on any securities exchange or to arrange for the notes to be quoted on any quotation system. The underwriters have advised us that they intend to make a

S-33

market in the notes. However, they are not obligated to do so and they may discontinue any market making at any time in their sole discretion. Therefore, we cannot assure you that a liquid trading market will develop for the notes, that you will be able to sell your notes at a particular time or that the prices that you receive when you sell will be favorable.

In connection with the offering, the underwriters may engage in overallotment, stabilizing transactions and syndicate covering transactions. Overallotment involves sales in excess of the offering size, which creates a short position for the underwriters. Stabilizing transactions involve bids to purchase the notes in the open market for the purpose of pegging, fixing or maintaining the price of the notes. Syndicate covering transactions involve purchases of the notes in the open market after the distribution has been completed in order to cover short positions. Stabilizing transactions and syndicate covering transactions may cause the price of the notes to be higher than it would otherwise be in the absence of those transactions. If the underwriters engage in stabilizing or syndicate covering transactions, they may discontinue them at any time.

We intend to use more than 10% of the net proceeds from the sale of the notes to repay indebtedness owed by us to certain of the underwriters or their affiliates. Accordingly, the offering is being made in compliance with the requirements of Rule 2710(h) of the Conduct Rules of the National Association of Securities Dealers, Inc. This rule provides generally that if more than 10% of the net proceeds from the sale of debt securities, not including underwriting compensation, is paid to the underwriters of such debt securities or their affiliates, the yield on the securities may not be lower than that recommended by a “qualified independent underwriter” meeting certain standards. Accordingly, Credit Suisse Securities (USA) LLC is assuming the responsibilities of acting as the qualified independent underwriter in pricing the offering and conducting due diligence. The yield on the notes, when sold to the public at the public offering price set forth on the cover page of this prospectus, is no lower than that recommended by Credit Suisse Securities (USA) LLC.

The underwriters or their affiliates have from time to time provided investment banking, commercial banking and financial advisory services to us and our affiliates, for which they have received customary compensation. The underwriters and their affiliates may provide similar services in the future. In particular, certain of the underwriters or their affiliates are lenders under our bank credit facility and will receive the net proceeds from this offering used to pay down our bank credit facility. In addition, from time to time, certain of our underwriters and their affiliates may effect transactions for their own account or the account of customers, and hold on behalf of themselves or their customers, long or short positions in our debt or equity securities or loans, and may do so in the future.

J.P. Morgan Trust Company, National Association, an affiliate of J.P. Morgan Securities, will serve as trustee under the indenture which will govern the notes being offered hereby. JPMorgan Chase & Co. (“JPMorgan”) has entered into an agreement with The Bank of New York Company, Inc. (“BNY”) pursuant to which JPMorgan intends to exchange portions of its corporate trust business, including municipal and corporate trusteeships, for BNY’s consumer, small business and middle market banking businesses. This transaction has been approved by both companies’ boards of directors and is subject to regulatory approvals. It is expected to close in the late third quarter or fourth quarter of 2006.

Proved Developed Non-Producing Reserves— Reserves that consist of (i) proved reserves from wells which have been completed and tested but are not producing due to lack of market or minor completion problems which are expected to be corrected and (ii) proved reserves

S-36

currently behind the pipe in existing wells and which are expected to be productive due to both the well log characteristics and analogous production in the immediate vicinity of the wells.

Proved Developed Producing Reserves— Proved reserves that can be expected to be recovered from currently producing zones under the continuation of present operating methods.

Proved Developed Reserves— Proved reserves that can be expected to be recovered through existing wells with existing equipment and operating methods.

Proved Reserves— The estimated quantities of crude oil, natural gas and natural gas liquids which geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions.

Forward-looking statements

This prospectus and the documents incorporated by reference in this prospectus contain “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. These statements include statements relating to our plans, strategies, objectives, expectations, intentions and adequacy of resources and are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. In general, all statements other than statements of historical fact are forward-looking statements. These forward-looking statements are based on management’s current belief, based on currently available information, as to the outcome and timing of future events. However, management’s assumptions and our future performance are subject to a wide range of business risks and uncertainties and we cannot assure you that these goals and projections can or will be met. Any number of factors could cause actual results to differ materially from those in the forward-looking statements, including, but not limited to:


•	production variance from expectations,

•	volatility of oil and natural gas prices,

•	hedging results,

•	the need to develop and replace reserves,

•	the substantial capital expenditures required to fund operations,

•	exploration risks,

•	environmental risks,

•	uncertainties about estimates of reserves,

•	competition,


•	litigation,

•	our sources of liquidity,

•	access to capital,

•	government regulation,

•	political risks,

•	our ability to implement our business strategy,

•	costs and results of drilling new projects,

•	mechanical and other inherent risks associated with oil and natural gas production,

•	weather,

•	availability of drilling equipment, and

•	changes of interest rates.

Reserve engineering is a process of estimating underground accumulations of oil and natural gas that cannot be measured in an exact way. The accuracy of any reserve estimate depends on the quality of available data, the interpretation of such data and price and cost assumptions made by our reserve engineers. In addition, the results of drilling, testing and production activities may justify revisions of estimates that were made previously. If significant, such revisions would change the schedule of any further production and development drilling. Accordingly, reserve estimates may differ from the quantities of oil and natural gas that are ultimately recovered.

Should one or more of the risks or uncertainties described in this prospectus or the documents we incorporate by reference, or should underlying assumptions prove incorrect, our actual results and plans could differ materially from those expressed in any forward-looking statements. We undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

All forward-looking statements express or implied, included in this prospectus and the documents we incorporate by reference and attributable to Range are expressly qualified in their entirety by this cautionary statement. This cautionary statement should also be considered in connection with any subsequent written or oral forward-looking statements that Range or persons acting on its behalf may issue.

Use of proceeds

Unless we inform you otherwise in a prospectus supplement, we expect to use the net proceeds from the sale of the securities covered by this prospectus for general corporate purposes, which may include but are not limited to reduction or refinancing of debt or other corporate obligations, repurchasing or redeeming our securities, the financing of capital expenditures, acquisitions and additions to our working capital. We may temporarily use the net proceeds received from any offering of securities to repay our senior credit facility or other debt until we can use such net proceeds for the stated purpose.

Description of debt securities

In this Description of Debt Securities, “Range” or “the Company” refers only to Range Resources Corporation, and any successor obligor on the securities, and not to any of its subsidiaries. You can find the definitions of certain terms used in this description under “—Certain definitions.”

The Company may from time to time issue such securities (referred to herein as the “notes”) under an Indenture between the Company, the Subsidiary Guarantors and J.P. Morgan Trust Company, N.A., to be entered into prior to issuance of the notes. The terms of the notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended.

The notes may be issued from time to time as provided in this prospectus. When notes are offered, a prospectus supplement will explain the particular terms of the notes to the extent they are not set forth in or vary from the terms set forth in this prospectus, and in particular will include the following information about the notes offered:


•	the initial principal amount of notes offered,

•	the interest rate borne by the notes,

•	the interest payment dates and related record date,

•	the maturity date,

•	the prices and other terms, if any, upon which the notes may be redeemed prior to maturity,

•	any changes in the terms related to the notes described herein, including changes in covenants, events of default or any other provision described herein, and

•	any other information relevant to the terms of the notes so offered.

The following is a summary of the material provisions of the Indenture. Because this is a summary, it may not contain all the information that is important to you. We have filed the form of Indenture as an exhibit to the registration statement of which this prospectus is part. You should read the Indenture in its entirety.

Basic terms of notes

The notes


•	will be unsecured senior subordinated obligations of Range, subordinated in right of payment to all existing and future Senior Debt of Range in accordance with the subordination provisions of the Indenture;

•	will be jointly, severally and unconditionally guaranteed on a senior subordinated basis by certain of the material domestic Restricted Subsidiaries of the Company and any future material domestic 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;

•	will rank equally with all of our senior subordinated unsecured debt, including $200.0 million in aggregate principal amount of our outstanding 7³/8 % Senior Subordinated Notes and our


	$150.0 million in aggregate principal amount of our outstanding 6³/8 % Senior Subordinated Notes;

Additional notes

Subject to the covenants described below, following the initial issuance of notes under the Indenture, we may issue additional notes under the Indenture having the same terms as the initial notes; provided, however, that any such issuance made under the same CUSIP number as the original issuance will be made only if either such additional notes are issued with no more than de minimis original issue discount or such issuance is a “qualified reopening” as such term is defined under Treasury regulations section 1.1275-2(k)(3) promulgated under the Internal Revenue Code of 1986, as amended. The initial notes and any such 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 with respect to the notes.

Optional redemption

We will be permitted to redeem the notes prior to maturity on the terms and at the prices set forth in the prospectus supplement relating to the issuance of the notes.

No mandatory redemption or sinking fund

Except as set forth below under “—Repurchase at the option of holders,” we will not be 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”) initially by certain of the Company’s material domestic Restricted Subsidiaries of the Company and by any future material domestic Restricted Subsidiaries of the Company. The initial Subsidiary Guarantors shall be Great Lakes Energy Partners, L.L.C., Range Energy I, Inc., Range HoldCo, Inc., Range Production Company, Range Energy Ventures Corporation, Range Operating New Mexico, Inc. and PMOG Holdings, Inc. 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 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.

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.

Subordination

The payment of principal, 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”).

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

As a result of the subordination provisions described above, in the event of a liquidation or insolvency of the Company, Holders of notes may recover less ratably than creditors of the Company who are holders of Senior Debt. 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, unless a notice of redemption has been given with respect to the notes, 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 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 will 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 upon a Change of Control 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 will prohibit 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) that 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 shall be treated as cash for the foregoing purposes.

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 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 $10.0 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 in an amount equal to, in the case of the notes, 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 sum of the aggregate principal amount of the notes surrendered by Holders thereof and the aggregate principal amount or accreted value, as the case may be, of other Pari Passu Indebtedness surrendered by holders or lenders thereof 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 will prohibit 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 Indenture provides that the Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly: (i) declare or pay any dividend or make any other payment or distribution on account of the 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) or 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 of the Company; (iii) make any principal payment on, or purchase, redeem, defease or otherwise acquire or retire for value any Indebtedness that is subordinated to the notes, except at final maturity; or (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) and (6) of the next succeeding paragraph), is less than the sum of (i) the dollar amount calculated as of the date of the Indenture under Section 4.07(c) of that certain Indenture dated July 21, 2003 among the Company, the Subsidiary Guarantors and J.P. Morgan Trust Company, National Association as successor trustee to Bank One, National Association, plus (ii) 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 (iii) 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 (iv) 100% of the amount of net cash proceeds received by the Company or a Restricted Subsidiary from the sale within 12 months of the related acquisition of any of the following that are acquired after the date of the Indenture in

exchange for Equity Interests of the Company (other than Disqualified Stock and other than Capital Stock issued to a Subsidiary of the Company): (A) any property or assets (other than Indebtedness and Capital Stock); (B) the Capital Stock of a Person that becomes a Restricted Subsidiary as a result of the acquisition of such Capital Stock by the Company or another Restricted Subsidiary; or (C) Capital Stock constituting a minority interest in any Person that at such time is a Restricted Subsidiary, plus (v) 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.

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)(iii) or (c)(iv) of the preceding paragraph; (3) the defeasance, redemption or repurchase of Subordinated Indebtedness with the net cash proceeds from an incurrence of 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)(iii) or (c)(iv) of the preceding paragraph; (4) the repurchase, redemption or other acquisition or retirement for value of any Equity Interests of the Company or any Subsidiary of the Company held by any of the Company’s (or any of its Subsidiaries’) employees pursuant to any 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; and (6) cash payments made by the Company for the repurchase, redemption or other acquisition or retirement of the Company’s 7³/8% Senior Subordinated Notes due 2013 or 6³/8 % Senior Subordinated Notes due 2015.

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 a Restricted Investment or, if applicable, a Permitted Investment at the time of such designation and must comply with 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 Indenture provides that the Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness (including Acquired Debt) and that 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.

Notwithstanding the foregoing, the Indenture will not prohibit any of the following (collectively, “Permitted Indebtedness”): (a) the Indebtedness evidenced by the notes initially issued under the Indenture; (b) the Indebtedness evidenced by the Company’s 7³/8% Senior Subordinated Notes or 6³/8 % Senior Subordinated Notes; (c) 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 incurred pursuant to this clause (c) and outstanding under all Credit Facilities does not, at any one time, exceed the greater of (i) $600.0 million and (ii) an amount equal to the sum of (A) $50.0 million plus (B) 30% of Adjusted Consolidated Net Tangible Assets determined after the incurrence of such Indebtedness (including the application of the proceeds therefrom); (d) the guarantee by any Subsidiary Guarantor of any Indebtedness that is permitted by the Indenture to be incurred by the Company; (e) all Indebtedness of the Company and its Restricted Subsidiaries in existence as of the date of the Indenture; (f) 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; (g) 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; (h) 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; (i) 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; (j) 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 (j) together with all Permitted Refinancing Debt incurred pursuant to clause (k) of this paragraph in respect of Indebtedness previously incurred pursuant to this clause (j), does not exceed $10.0 million at any one time outstanding; (k) 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 Indent ure to be incurred (including Indebtedness previously incurred pursuant to this clause (k) and Indebtedness referred to in clause (e) above); (l) 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; and (m) Indebtedness consisting of obligations in respect of purchase price adjustments, guarantees or indemnities in connection with the acquisition or disposition of assets.

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

For purposes of determining compliance with, and the outstanding principal amount of any particular Indebtedness incurred pursuant to and in compliance with this covenant: (A) Indebtedness permitted by this covenant need not be permitted solely by reference to one provision permitting such Indebtedness but may be permitted in part by one such provision and in part by one or more other provisions of this covenant permitting such Indebtedness, (B) in the event that Indebtedness meets the criteria of more than one of the types of Indebtedness permitted by this covenant to be incurred, the Company, in its sole discretion, will classify such item of Indebtedness on the date of incurrence (or later reclassify such Indebtedness from or after the first date on which the Company or its Restricted Subsidiaries could have incurred such Indebtedness under one or more other of such provisions) and only be required to include the amount and type of such Indebtedness in one or more of such provisions as it determines; and (C) the amount of any Indebtedness issued at a price that is less than the principal amount thereof will be equal to the amount of the liability in respect thereof determined in accordance with GAAP.

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

Dividend and other payment restrictions affecting subsidiaries

The Indenture provides that the Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to exist or become effective any consensual 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 and the indentures governing the Company’s 7³/8% Senior Subordinated Notes and 6³/8 % Senior Subordinated Notes, each 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 or indenture or other financing agreement or instrument, provided that such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements, refinancings or other Credit Facilities or indentures or other financing agreements or instruments are not materially more restrictive taken as a whole with respect to such dividend and other payment restrictions than those contained in the Credit Agreement and such indentures as in effect on the date of the Indenture, (b) the Indenture and the notes, (c) applicable law, (d) any instrument governing Indebtedness or Capital Stock of a Person acquired by the Company or any of its Restricted Subsidiaries as in effect at the time of such acquisition (except, in the case of Indebtedness, to the extent such Indebtedness was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person and its Subsidiaries, or the property or assets of the Person and its Subsidiaries, so acquired, provided that, 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 not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced.

Merger, consolidation on sale of substantially all assets

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

Transactions with affiliates

The Indenture provides that the Company will not, and will not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any of its Affiliates (each of the foregoing, an “Affiliate Transaction”), unless (i) such Affiliate Transaction is on terms that are no less favorable to the Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such 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 $10.0 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 $10.0 million but less than or equal to $25.0 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 $25.0 million, the Company delivers 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 an opinion as to the fairness to the Company or such Subsidiary of such Affiliate Transaction or series of related Affiliate Transactions (which resolution and fairness opinion shall be conclusive evidence of compliance with this provision) 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, (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,” (4) indemnification payments made to officers, directors and employees of the Company or any Subsidiary pursuant to charter, bylaw, statutory or contractual provisions, and (5) transactions with entities that are Affiliates of the Company or a Restricted Subsidiary only because of the ownership by the Company or a Restricted Subsidiary of Equity Interests in such entity.

Additional subsidiary guarantees

The Indenture provides that if the Company or any of its Restricted Subsidiaries shall acquire or create another material 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; provided that, in no event will any non-U.S. Subsidiary of the Company be required to execute a Guarantee. For purposes of the foregoing, a Restricted Subsidiary shall be deemed to be “material” if it would not be a minor subsidiary within the meaning of Rule 3-10(h) of Regulation S-X under the Exchange Act.

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 will also comply with the other provisions of Section 314(a) of the Trust Indenture Act.

Events of default and remedies

The Indenture provides that 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 now exists, or is created after the date of the Indenture, 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 the maturity of which has been so accelerated, aggregates $10.0 million or more; provided, that if any such default is cured or waived or any such acceleration 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 $10.0 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. Upon such declaration the principal and interest shall be due and payable immediately; provided, however, that so long as any Designated Senior Debt or any commitment therefor is outstanding, any such notice or declaration shall not become effective until the earlier of (a) five Business Days after such notice is delivered to the representative for the Designated Senior Debt or (b) the acceleration of any Designated Senior Debt and thereafter, payments on the Securities pursuant the above provisions shall be made only to the extent permitted pursuant to the subordination provisions of the indenture. 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 or the Indenture or for any claim based on, in respect of, or by reason of,-such obligations or their creation. 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.

Amendment, 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 Event of 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).

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 rescission 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 66²/3 % 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 add Subsidiary Guarantors, 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.

Satisfaction and discharge

The Indenture will be discharged and will cease to be of further effect as to all notes issued thereunder, when: (1) either (a) all notes that have been authenticated (except lost, stolen or destroyed notes that have been replaced or paid and notes for whose payment money has theretofore been deposited in trust and thereafter repaid to the Company) have been delivered to the trustee for cancellation, or (b) all notes that have not been delivered to the trustee for cancellation have become due and payable by reason of the giving of a notice of redemption or otherwise or will become due and payable (including pursuant to a notice of redemption duly given) within one year and the Company or any Subsidiary Guarantor has irrevocably deposited or caused to be irrevocably deposited with the trustee as trust funds in trust solely for the benefit of the holders, cash in U.S. dollars, non-callable U.S. government

securities, or a combination thereof, in such amounts as will be sufficient without consideration of any reinvestment of interest, to pay and discharge the entire indebtedness on the notes not delivered to the trustee for cancellation for principal, premium, if any, and accrued interest to the date of maturity or redemption; (2) no Default or Event of Default shall have occurred and be continuing on the date of such deposit or shall occur as a result of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit) and such deposit will not result in a breach or violation of, or constitute a default under, any instrument (other than the indenture) to which the Company or any Subsidiary Guarantor is a party or by which the Company or any Subsidiary Guarantor is bound; (3) the Company or any Subsidiary Guarantor has paid or caused to be paid all other sums payable by it under the indenture; and (4) the Company has delivered an Officers’ Certificate and an opinion of counsel to the trustee stating that all conditions precedent to satisfaction and discharge have been satisfied.

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. 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 with respect to the Company) 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 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 (vii) 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.

Concerning the trustee

J.P. Morgan Trust Company, N.A. is the Trustee under the Indenture. The Trustee and its affiliates also perform and may in the future perform certain banking and other services for us in the ordinary course of their business. The Trustee will be the paying agent, conversion agent, transfer agent and bid solicitation agent for the notes.

The Trustee assumes no responsibility for this prospectus and has not reviewed or undertaken to verify any information contained in this prospectus.

Form, denomination and registration of the notes

The notes will be issued in registered form, without interest coupons, in denominations of $1,000 and integral multiples thereof, in global form. Except in the limited circumstances described below, notes will not be issued in certificated form.

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 purchased pursuant to an Offer to Purchase, (ii) to register the transfer of or exchange any note so selected for redemption or purchase in whole or in part, except, in the case of a partial redemption or purchase, that portion of any the note not being redeemed or purchased, or (iii) if a redemption or a purchase pursuant to an Offer to Purchase 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 purchase.

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 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 global notes 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.

Same day settlement and payment

The Indenture will require 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 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.

Governing law

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