PROSPECTUS SUMMARY
      This summary highlights information contained elsewhere in this prospectus and the documents incorporated by reference. Because it is a summary, it does not contain all of the information that you should consider before deciding to exchange your old notes for new notes. You should read the entire prospectus and the documents incorporated by reference carefully, including the section entitled “Risk Factors” and the financial statements and related notes to those financial statements incorporated by reference in this prospectus.
      Unless otherwise noted herein, as used in this prospectus, “we,” “our,” “ours,” “us” and the “Company” refer to Range Resources Corporation and its subsidiaries, except where the context otherwise requires or as otherwise indicated.
Our Company
      We are an independent oil and natural gas company engaged in the acquisition, development and exploration of oil and natural gas properties, in the Southwest, Appalachia and Gulf Coast, including the Gulf of Mexico, regions of the United States. We seek to increase our reserves and production through a balanced combination of development drilling, exploitation projects, exploration and acquisitions.
      We have a geographically diverse asset base focused on three core areas. The Southwest division’s properties are located in the Permian Basin of West Texas, the East Texas Basin, the Anadarko Basin of western Oklahoma and the Texas Panhandle. Our Gulf Coast division operates properties onshore in Texas, Louisiana and Mississippi and holds a non-operating interest in approximately 40 offshore properties in the shallow waters of the Gulf of Mexico. In 1999 we formed Great Lakes Energy Partners L.L.C. (“Great Lakes”), a joint venture 50% owned by us and 50% owned by FirstEnergy Corp. (“FirstEnergy”). On June 23, 2004 we consummated the acquisition of the 50% of Great Lakes that we did not previously own pursuant to a Purchase and Sale Agreement by and between the Company and FirstEnergy, thereby expanding our production in the Appalachian Basin. At closing, we paid cash consideration of $200 million, assumed $70 million of Great Lakes bank debt and retired $28 million of oil and gas commodity hedges for a total purchase price of $298 million. We funded the acquisition with the proceeds of $149 million from an underwritten public offering of our common stock, the sale of $100 million of our 73/8% senior subordinated notes due 2013 and bank borrowings pursuant to the Second Amended and Restated Credit Agreement (the “Senior Credit Facility”). As a result of the acquisition transaction, the borrowing base under the Senior Credit Facility was increased from $240 million to $500 million. On December 10, 2004 we acquired additional Appalachian oil and gas properties with the purchase of PMOG Holdings, Inc., a private company (“Pine Mountain”). The purchase price was $222 million. We funded the acquisition with the proceeds of $108 million from an underwritten public offering of 5.75 million shares of our common stock and bank borrowings pursuant to our Senior Credit Facility. In connection with the acquisition of Pine Mountain, our lenders increased the Senior Credit Facility borrowing base from $500 million to $575 million.
      Our principal executive offices are located at 777 Main Street, Suite 800, Fort Worth, Texas 76102. Our telephone number is 817.870.2601.
Recent Developments
Private placement of 63/8 Senior Subordinated Notes
      On March 9, 2005, we completed the private offering of $150 million of 63/8% senior subordinated notes due 2015. The proceeds from the offering were used to pay down our Senior Credit Facility to a balance of $277.4 million.

The Exchange Offer
      On March 9, 2005, we completed a private offering of the old notes. We entered into a registration rights agreement with the initial purchasers in the private offering of the old notes in which we agreed, among other things, to deliver this prospectus to you and to use our reasonable best efforts to consummate the exchange offer within 210 days following the date of the original issuance of the old notes. The following is a summary of the exchange offer.
Exchange Offer We are offering to exchange new notes for old notes.
 
Expiration date The exchange offer will expire at 5:00 p.m. New York City time, on May 19, 2005, unless we decide to extend it. We do not currently intend to extend the exchange offer. The exchange offer must remain open for not less than thirty days (or longer if required by applicable law) after the date notice of the exchange offer is mailed to holders of the old notes.
 
Condition to the exchange offer The registration rights agreement does not require us to accept old notes for exchange if the exchange offer or the making of any exchange by a holder of the old notes would violate any applicable law or interpretation of the staff of the Securities and Exchange Commission. The tender of a minimum aggregate principal amount of old notes is not a condition to the exchange offer.
 
Procedures for tendering old notes To participate in the exchange offer, you must follow the automated tender offer program, or ATOP, procedures established by The Depository Trust Company, or DTC, for tendering notes held in book-entry form. The ATOP procedures require that the exchange agent receive, prior to the expiration date of the exchange offer, a computer-generated message known as an “agent’s message” that is transmitted through ATOP and that DTC confirm that:
 
• DTC has received instructions to exchange your old notes; and
 
• you agree to be bound by the terms of the letter of transmittal.
 
For more information on tendering your old notes, please refer to the sections in this prospectus entitled “Exchange Offer — Terms of the Exchange Offer,” “— Procedures for Tendering” and “— Book-Entry Transfer.”
 
Guaranteed delivery procedures None.
 
Withdrawal of tenders You may withdraw your tender of old notes at any time prior to the expiration date. To withdraw, you must submit a notice of withdrawal to the exchange agent using ATOP procedures before 5:00 p.m., New York City time, on the expiration date of the exchange offer.
 
Acceptance of old notes and delivery of new notes If you fulfill all conditions required for proper acceptance of old notes, we will accept any and all old notes that you properly tender in the exchange offer on or before 5:00 p.m., New York City time, on the expiration date. We will return any old notes that we do not accept for exchange to you without expense as promptly as practicable after the expiration date. We will also deliver the new notes as promptly as practicable after the expiration date. Please refer to

Table of Contents

  the section in this prospectus entitled “Exchange Offer — Terms of the Exchange Offer.”
Resale We believe that the new notes issued pursuant to the exchange offer may be offered for resale, resold and otherwise transferred by you (unless you are an “affiliate” of ours within the meaning of Rule 405 under the Securities Act) without compliance with the registration and prospectus delivery provisions of the Securities Act so long as you are acquiring the new notes in the ordinary course of your business and you have not engaged in, do not intend to engage in, and have no arrangement or understanding with any person to participate in, a distribution of the new notes.
 
Each participating broker-dealer that receives new notes for its own account under the exchange offer for old notes that were acquired by the broker-dealer as a result of market-making or other trading activity must acknowledge that it will deliver a prospectus in connection with any resale of the new notes. See “Plan of Distribution.”
 
Any holder of old notes who:
 
• is our affiliate
 
• does not acquire new notes in the ordinary course of its business; or
 
• exchanges old notes in the exchange offer with the intention to participate, or for the purpose of participating, in a distribution of new notes,
 
must, in the absence of an exemption, comply with the registration and prospectus delivery requirements of the Securities Act in connection with the resale of the new notes.
 
Fees and Expenses We will bear all expenses related to the exchange offer. Please refer to the section in this prospectus entitled “Exchange Offer — Fees and Expenses.”
 
Use of proceeds The issuance of the new notes will not provide us with any new proceeds. We are making this exchange offer solely to satisfy our obligations under our registration rights agreement.
 
Consequences of failure to exchange old notes If you do not exchange your old notes in this exchange offer, you will no longer be able to require us to register the old notes under the Securities Act except in the limited circumstances provided under our registration rights agreement. In addition, you will not be able to resell, offer to resell or otherwise transfer the old notes unless we have registered the old notes under the Securities Act, or unless you resell, offer to resell or otherwise transfer them under an exemption from the registration requirements of, or in a transaction not subject to, the Securities Act.
 
Tax consideration We believe that the exchange of new notes for old notes should not be an exchange or otherwise a taxable event to a holder for United States federal income tax purposes. Please read “United States Federal Income Tax Considerations.”

The new notes will evidence the same debt as the old notes, and the same indenture will govern the new note and the old notes. When we use the term “notes,” we mean the new notes together with the old notes.
      The following summary contains basic information about the new notes and is not intended to be complete. It does not contain all the information that is important to you. For a more complete understanding of the new notes, please refer to the section of this document entitled “Description of the New Notes.”
Issuer Range Resources Corporation.
 
Notes offered $150 million aggregate principal amount of 63/8% Senior Subordinated Notes due 2015.
 
Maturity date March 15, 2015.
 
Interest payment dates March 15 and September 15 of each year, commencing on September 15, 2005.

Optional redemption Except as otherwise described below, the new notes will not be redeemable at our option prior to March 15, 2010. Thereafter, the new notes will be subject to redemption at our option, in whole or in part, at the redemption prices set forth under the heading “Description of the New Notes — Optional Redemption,” plus accrued and unpaid interest thereon to the applicable redemption date. In addition, prior to March 15, 2008, we may, at our option, on any one or more occasions, redeem up to 35% of the original aggregate principal amount of the notes at a redemption price equal to 106.375% of the principal amount thereof, plus accrued and unpaid interest, if any, to the redemption date, with all or a portion of the net proceeds of public sales of equity interests of the Company; provided that at least 65% of the original aggregate principal amount of the notes remains outstanding immediately after the occurrence of such redemption. See “Description of the New Notes — Optional Redemption.”
 
Change of control Upon a “Change of Control,” you as a holder of the notes will have the right to require us to make an offer to repurchase all or a portion of the notes at a purchase price of 101% of their aggregate principal amount, plus accrued and unpaid interest, if any, to the date of repurchase. Our Senior Credit Facility prohibits us from repurchasing any notes pursuant to a change of control offer prior to the repayment in full of the senior debt under our credit agreement. Therefore, if a change of control were to occur, there can be no assurance that we or the subsidiary guarantors will have the financial resources or be permitted under the terms of our or their indebtedness to repurchase the notes. If any “event of default” occurs, the trustee or holders of at least 25% in principal amount of the notes then outstanding may declare the principal of and the accrued and unpaid interest on such notes to be due and payable immediately. However, such repayment would be subject to the subordination provisions in our Indenture. See “Description

Ranking The new notes will be general, unsecured obligations, will be subordinated in right of payment to our senior debt, which includes borrowings under our Senior Credit Facility and any other permitted indebtedness which does not expressly provide that it is on a parity with or subordinated in right of payment to the new notes. The new notes and the old notes will constitute a single class of securities under the Indenture. See “Capitalization” and “Description of the New Notes — Subordination.”
 
Subsidiary guarantees Our payment obligations under the new notes will be jointly, severally and unconditionally guaranteed on a senior subordinated basis by each of our restricted subsidiaries and any future restricted subsidiaries. The guarantees will be subordinated to senior debt of the subsidiary guarantors to the same extent and in the same manner as the new notes are subordinated to senior debt. See “Description of the New Notes — Guarantees.”
 
Certain covenants The new notes will be issued pursuant to the same Indenture as the old notes. This Indenture contains certain covenants that will, among other things, limit the ability of us and our restricted subsidiaries to incur additional indebtedness and issue disqualified stock, pay dividends, make distributions, make investments, make certain other restricted payments, enter into certain transactions with affiliates, dispose of certain assets, incur liens securing indebtedness of any kind (other than permitted liens) and engage in mergers and consolidations. See “Description of the New Notes — Certain Covenants.”
 
Transfer restrictions; absence of a public market for the new notes The new notes generally will be freely transferable, but will also be new securities for which there is no existing market.

RISK FACTORS
      You should carefully consider and evaluate all the information included or incorporated by reference in this prospectus, including the risks described below, before you decide to participate in the exchange offer. Our business, financial condition and results of operations could be materially adversely affected by any of these risks. The trading price of the notes could decline, and you may lose all or part of your investment. The risks described below are not the only ones facing our company. Additional risks not presently known to us or that we currently deem immaterial individually or in the aggregate may also impair our business operations.
      This prospectus and the documents incorporated by reference also contain forward-looking statements that involve risks and uncertainties, some of which are described in the documents incorporated by reference in this prospectus. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of various factors, including the risks and uncertainties faced by us described below or incorporated by reference in this prospectus.
Risks related to our business
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 typically is cyclical, and prices for oil and natural gas can be 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 $56 per barrel and natural gas prices reaching $10 per mcf in some markets. These record oil and natural gas prices have contributed to our positive earnings over the last 18-24 months. 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 may be unable to replace production.
Hedging transactions may limit our potential gains and involve other risks
      To manage our exposure to price risk, we enter into hedging arrangements from time to time with respect to a portion of our future production. The goal of these hedges is to 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 example, at December 31, 2004, we were party to hedging arrangements covering 19.7 Bcf and 0.6 million barrels of oil and 0.2 million barrels of NGLs. We also had collars covering 37.8 Bcf of gas and 2.8 million barrels of oil. The hedges’ fair value was a pre-tax loss of $71.9 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

8


Table of Contents

  •  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.
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 expenditures 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 additional write-downs of our oil and natural gas properties
      In the past, we have been required to write down the carrying value of our oil and natural gas properties, and there is a risk that we will be required to take additional 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 or deterioration in our exploration results.
      Accounting rules require that the carrying value of oil and natural gas properties be periodically reviewed for possible impairment. “Impairment” is recognized when the book value of a proven property is greater than the expected undiscounted future cash flows from that property and on acreage when 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 development results, production data, economics and other factors. While an impairment charge which reflects our long-term ability to recover on a prior investment does not impact cash or cash flow from operating activities, it reduces our earnings and increases our leverage ratios.
      For example, based primarily on the poor performance of certain properties acquired in 1997 and 1998 and significantly lower oil and natural gas prices, we recorded impairments of $215.0 million in 1998 and $29.9 million in 1999. At year-end 2001, we recorded an impairment of $31.1 million due to 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.
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 and explosions, uncontrollable flows of oil, natural gas or well fluids, fires, formations with abnormal pressures, pipelines 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;

9


Table of Contents

  •  regulatory investigations and penalties; and/or
 
  •  suspension of operations.
      Our current and former operations are subject to numerous and increasingly strict federal, state and local laws, regulations and enforcement policies relating to the environment. We may incur significant costs and liabilities in complying with existing or future environmental laws, regulations and enforcement policies and may incur costs arising out of property damage or injuries to employees and other persons. These costs may result from our current and former operations and even may be caused by previous owners of property we own or lease. Any past, present or future failure by us to completely comply with environmental laws, regulations and enforcement policies could cause us to incur substantial fines, sanctions or liabilities 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. 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 December 31, 2004, approximately 40% of our debt is at fixed interest rates with the remaining 60% 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. 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, 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.

Table of Contents

      For example, in 1997 we consummated a large acquisition which proved extremely disappointing. Production from the acquired properties fell more rapidly than anticipated and further development results were far below the results we had originally projected. The poor production performance of these properties resulted in material downward reserve revisions. We cannot assure you that our recent and/or future acquisition activity will not result in similar 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 strategy of completing acquisitions 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. Possible 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 senior management personnel, none of which are currently subject to an employment contract. The loss of one or more of these individuals could have a material adverse effect on our business. Furthermore, competition for experienced 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 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 materially as reserves are produced. Future oil and natural gas production is, therefore, highly dependent upon our level of success in acquiring or finding additional reserves that are economically recoverable. We cannot assure you that we will be able to find and develop or acquire additional reserves at an acceptable cost.
A portion of our business is subject to special risks related to offshore operations generally and in the Gulf of Mexico specifically
      Offshore operations are subject to a variety of operating risks specific to the marine environment, such as capsizing, collisions and damage or loss from hurricanes or other adverse weather conditions. These conditions can cause substantial damage to facilities and interrupt production. As a result, we could incur substantial liabilities that could reduce or eliminate the funds available for exploration, development or leasehold acquisitions, or result in loss of equipment and properties.
      Production of reserves from reservoirs in the Gulf of Mexico generally declines more rapidly than from reservoirs in many other producing regions of the world. This results in recovery of a relatively higher percentage of reserves from properties in the Gulf of Mexico during the initial few years of production. As a result, reserve replacement needs from new prospects are greater and require us to incur significant capital expenditure to replace production.

New technologies may cause our current exploration and drilling methods to become obsolete
      The oil and natural gas industry is subject to rapid and significant advancements in technology, including the introduction of new products and services using new technologies. As competitors use or develop new technologies, we may be placed at a competitive disadvantage, and competitive pressures may force us to implement new technologies at a substantial cost. In addition, competitors may have greater financial, technical and personnel resources that allow them to enjoy technological advantages and may in the future allow them to implement new technologies before we can. 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, some of which are owned by others
      The marketability of our oil and natural gas production depends in part on the availability, proximity and capacity of pipeline systems owned by third parties. The unavailability of or lack of available capacity on these systems and facilities could result in the shut-in of producing wells or the delay or discontinuance of development plans for properties. Although we have some contractual control over the transportation of our product, material changes in these business relationships could materially affect our operations. Federal and state regulation of oil and natural gas production and transportation, tax and energy policies, changes in supply and demand, pipeline pressures, damage to or destruction of pipelines and general economic conditions could adversely affect our ability to produce, gather and transport oil and natural gas.
Our financial statements are complex
      Due to accounting rules, our financial statements continue to be complex, particularly with reference to hedging, asset retirement obligations, stock options and the accounting for our deferred compensation plan. We expect such complexity to continue and possibly increase.
Risks related to the Exchange Offer and the New Notes
If you do not properly tender your old notes, you will continue to hold unregistered old notes and your ability to transfer old notes will be adversely affected
      We will only issue new notes in exchange for old notes that you timely and properly tender. Therefore, you should allow sufficient time to ensure timely delivery of the old notes and carefully follow the instructions on how to tender your old notes. Neither we nor the exchange agent are required to tell you of any defects or irregularities with respect to your tender of the old notes.
      If you do not exchange your old notes for new notes pursuant to the exchange offer, the old notes you hold will continue to be subject to the existing transfer restrictions. In general, you may not offer or sell the old notes except under an exemption from, or in a transaction not subject to, the Securities Act and applicable state securities laws. We do not plan to register old notes under the Securities Act. Further, if you continue to hold any old notes after the exchange offer is consummated, you may not be able to sell the old notes because there will be fewer old notes outstanding.
Our significant indebtedness could limit our ability to successfully operate our business and prevent us from fulfilling our obligations under the new notes
      We are leveraged and our exploration and development program will require substantial capital resources, estimated to range from $250 to $300 million per year over the next three years. The operation of 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.

12


Table of Contents

      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 economy generally;
 
  •  the terms of our existing credit arrangements and the indentures governing the notes contain numerous financial and other restrictive covenants which, if we fail to comply therewith, and an event of default occurs as a result of that failure, could have a material adverse effect on us;
 
  •  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.
      Any one or more of the foregoing could adversely affect our ability to use our cash flow from operations, or obtain additional financing, to continue our existing operations, including exploring and developing existing properties as presently anticipated, to consummate acquisitions, or to explore and develop newly acquired properties.
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 do not prohibit us from issuing additional 63/8% Senior Subordinated Notes or other indebtedness and the terms of the indenture governing the 73/8% Senior Subordinated Notes do not prohibit us from issuing additional 73/8% Senior Subordinated Notes or other indebtedness. As of December 31, 2004, our Senior Credit Facility permitted borrowings of $575 million, all of which would be senior to the notes. If new debt is added to our current debt levels, the related risks that we now face could intensify. See “Capitalization.”
Any failure to meet our debt obligations could harm our business, financial condition and
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 insufficient for payment of interest on and principal of our debt in the future, including payments on the new notes, and any such alternative measures may be unsuccessful or may not permit us to meet scheduled debt service obligations, which could cause us to default on our obligations and impair our liquidity.
Your right to receive payments on the new notes is subordinated to the rights of our senior indebtedness and effectively subordinated to the rights of existing and future creditors of any subsidiaries that are not guarantors on the new notes
      Holders of our senior indebtedness will have claims that are prior to your claims as holders of the new notes. In the event of any distribution of our assets in any foreclosure, dissolution, winding-up, liquidation, reorganization, or other, bankruptcy proceeding, holders of senior indebtedness will have prior claim to all of our assets. Holders of the new notes will participate ratably with all holders of our senior subordinated

13


Table of Contents

indebtedness that is deemed to be of the same class as the new notes, based upon the respective amounts owed to each holder or creditor, in our remaining assets. In any of the foregoing events, we cannot assure you that there will be sufficient assets to pay amounts due on the new notes. As a result, holders of the new notes may receive less, ratably, than holders of senior indebtedness.
      As of December 31, 2004, we had total of approximately $423.9 million outstanding on our Senior Credit Facility. We may incur an unlimited amount of indebtedness in the future under the terms of the Indenture.
      In addition, we conduct substantially all of our operations through our subsidiaries and some of our subsidiaries do not guarantee the new notes. In addition, we may be able to designate one or more subsidiaries in the future as unrestricted subsidiaries. As a result, holders of the new notes will be effectively subordinated to the indebtedness and other liabilities of any such subsidiaries, including trade creditors. Therefore, in the event of the insolvency or liquidation of an unrestricted subsidiary, following payment by such subsidiary of its liabilities, such subsidiary may not have sufficient remaining assets to make payments to us as a shareholder or otherwise. In the event of a default by any such subsidiary under any credit arrangement or other indebtedness, its creditors could accelerate such debt, prior to such subsidiary distributing amounts to us that we could have used to make payments on the new notes.
We may not be able to repurchase the notes
      Under the terms of the Indenture, you may require us to repurchase all or a portion of your new notes on certain dates or in the event of a change in control. We may not have enough funds to pay the repurchase price on a purchase date (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 new notes would be an event of default under such agreement. As a result, we may be restricted or prohibited from repurchasing or redeeming the new notes. If we are prohibited from repurchasing or redeeming the new notes, we could seek the consent of our then-existing lenders to repurchase or redeem the new notes or we could attempt to refinance the borrowings that contain such prohibition. If we are unable to obtain a consent or refinance the debt, we could not repurchase or redeem the new 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.
      The term “change in control” is limited to certain specified transactions and may not include other events that might adversely affect our financial condition. Our obligation to repurchase the new notes upon a change in control would not necessarily afford holders of the new 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 new notes a rating lower than the rating expected by investors, or reduces their rating in the future, the market price of the new notes would be adversely affected.
You may find it difficult to sell your new notes
      You may find it difficult to sell your new notes because an active trading market for the new notes may not develop.
      There is no existing trading market for the new notes. We do not know the extent to which investor interest will lead to the development of a trading market or how liquid that market might be. As a result, the market price of the new notes could be adversely affected.
Federal and state fraudulent transfer laws may permit a court to void the new notes and the guarantees and, if that occurs, you may not receive any payments on the new notes
      The issuance of the new 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

14


Table of Contents

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 new 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 evidenced by the new notes; or
 
  •  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 new notes or a guarantee was a fraudulent conveyance, the court could void the payment obligations under the new notes or such guarantee or subordinate the new notes or such guarantee to presently existing and future indebtedness of ours or such guarantor, or require the holders of the new notes to repay any amounts received with respect to the new notes or such guarantee. In the event of a finding that a fraudulent conveyance occurred, you may not receive any repayment on the new notes. Further, the voidance of the new 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; or
 
  •  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 new 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 new notes.
The market price of the new notes may fluctuate significantly, which may result in losses for investors
      The market price of the new notes could be volatile. We expect the market price of the new 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 new notes could decline as a result.

EXCHANGE OFFER
      We sold the old notes on March 9, 2005 pursuant to a purchase agreement dated March 2, 2005, by and among us and the initial purchasers named therein. The old notes were subsequently offered by the initial purchasers to qualified institutional buyers pursuant to Rule 144A under the Securities Act and outside the United States to persons other than U.S. persons in reliance on Regulation S under the Securities Act.
Purpose and Effect of the Exchange Offer
      In connection with the issuance of the old notes, we entered into a registration rights agreement under which we agreed to:
  •  within 90 days after the issue date of the old notes, file a registration statement with the Securities and Exchange Commission with respect to a registered offer to exchange the old notes for new notes of ours having terms substantially identical in all material respects to the old notes except with respect to transfer restrictions;
 
  •  use our reasonable best efforts to cause the registration statement to be declared effective under the Securities Act within 180 days after the issue date of the old notes;
 
  •  use our reasonable best efforts to consummate the exchange offer within 210 days after the issue date of the old notes;
 
  •  keep the exchange offer open for not less than 30 days (or longer if required by applicable law) after the date notice of the exchange offer is mailed to the holders of the old notes; and
 
  •  to file a shelf registration for the resale of the old notes if we cannot consummate the exchange offer within the time period listed above and certain other circumstances described in this prospectus.
      For each old note tendered to us pursuant to the exchange offer, we will issue to the holder of the old note a new note having a principal amount equal to that of the surrendered old note. Interest on each new note will accrue from the last date upon which we paid interest on the old note, unless no interest has been paid on the old note, in which case, interest shall be paid from the original issuance date of the old note.
      Under existing interpretations of the staff of the Securities and Exchange Commission issued to third parties, the new notes will be freely transferable by holders other than our affiliates after the exchange offer without further registration under the Securities Act if the holder of the new notes represents to us in the exchange offer that it is acquiring the new notes in the ordinary course of its business, that it has no arrangement or understanding with any person to participate in the distribution of the new notes and that it is not our affiliate, as such terms are interpreted by the Securities and Exchange Commission; provided, however, that broker-dealers receiving new notes in the exchange offer will have a prospectus delivery requirement with respect to resales of such new notes. The staff of the Securities and Exchange Commission has taken the position in interpretations issued to third parties that participating broker-dealers may fulfill their prospectus delivery requirements with respect to new notes (other than a resale of an unsold allotment from the original sale of the old notes) with the prospectus contained in the registration statement covering the new notes. Each broker-dealer that receives new notes for its own account in exchange for old notes, where such old notes were acquired by such broker-dealer as a result of market-making activities or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of such new notes. See “Plan of Distribution.”
      Under the registration rights agreement, we are required to allow participating broker-dealers and other persons, if any, with similar prospectus delivery requirements to use the prospectus contained in the registration statement in connection with the resale of the new notes for 180 days following the effective date of such registration statement (or such shorter period during which participating broker-dealers are required by law to deliver such prospectus).
      A holder of old notes (other than certain specified holders) who wishes to exchange old notes for new notes in the exchange offer will be required to represent that any new notes to be received by it will be

16


Table of Contents

acquired in the ordinary course of its business and that at the time of the commencement of the exchange offer it has no arrangement or understanding with any person to participate in the distribution (within the meaning of the Securities Act) of the new notes and that it is not our “affiliate,” as defined in Rule 405 of the Securities Act, or if it is an affiliate, that it will comply with the registration and prospectus delivery requirements of the Securities Act to the extent applicable.
      In the event that:
  •  any change of law or in applicable interpretations thereof by the staff of the Securities and Exchange Commission do not permit us to effect an exchange offer;
 
  •  for any other reason the exchange offer is not consummated within 210 days after the issue date of the old notes;
 
  •  any holder of old notes, other than the initial purchasers, notifies us prior to the 20th business day following the consummation of the exchange offer it is prohibited by law or the applicable interpretations of the staff of the Securities and Exchange Commission from participating in the exchange offer;
 
  •  in the case of any holder of old notes who participates in the exchange offer, such holder does not receive new notes on the date of the exchange that may be sold without restriction under state and federal securities laws (other than due solely to the status of such holders as an affiliate of ours within the meaning of the Securities Act); or
 
  •  an initial purchaser so requests with respect to old notes or new notes privately issued in exchange for old notes that have, or that are reasonably likely to be determined to have, the status of unsold allotments in an initial distribution;
then we will, at our cost, use our reasonable best efforts to file and use our reasonable best efforts to have declared effective a shelf registration statement covering resales of the old notes and any such privately issued new notes on or prior to the later of 180 calendar days after the issue date of the old notes or 90 days after the shelf registration statement is required to be filed with the Securities and Exchange Commission.
      We will use our reasonable best efforts to keep the shelf registration statement effective until two years after the issue date of the old notes, subject to certain exceptions. We will, if we file a shelf registration statement, among other things, provide to each holder for whom such shelf registration statement was filed copies of the prospectus which is a part of the shelf registration statement, notify each such holder when the shelf registration statement has become effective and take certain other actions as are required to permit unrestricted resales of the old notes or the new notes, as the case may be. A holder selling such old notes or new notes pursuant to the shelf registration statement generally would be required to be named as a selling security holder in the related prospectus and to deliver a prospectus to purchasers, will be subject to certain of the civil liability provisions under the Securities Act in connection with such sales and will be bound by the provisions of the registration rights agreement which are applicable to such holder (including certain indemnification obligations).
      The registration rights agreement obligates us to pay additional cash interest on the principal amount of the applicable old notes and new notes (in addition to the stated interest on the old notes and the new notes) upon the occurrence of any of the following events:
  •  if the registration statement of which this prospectus forms a part is not declared effective by the Securities and Exchange Commission on or prior to the 180th day after the issue date of the old notes (the “effectiveness deadline”);
 
  •  if the exchange offer is not consummated on or prior to the earlier of the 30th business day following the effectiveness deadline or the 210th day following the issue date of the old notes;
 
  •  if we are obligated to file the shelf registration statement, it is not declared effective by the later of 180 calendar days after the issue date of the old notes or 90 days after the shelf registration statement is required to be filed with the Securities and Exchange Commission; or

17


Table of Contents

  •  after the shelf registration statement is declared effective it ceases to be effective or usable (subject to some exceptions);
from and including the date on which any registration default shall occur to, but excluding, the earlier of (1) the date on which all registration defaults have been cured or (2) the date on which all the old notes and the new notes otherwise become freely transferable by holders other than our affiliates without further registration under the Securities Act. The additional cash interest will accrue at a rate of ..25% per annum during the 90 day period immediately following the occurrence of a registration default and shall increase by an additional .25% per annum with respect to each subsequent 90 day period, up to a maximum amount of additional interest of .50% per annum.
Resale of New Notes
      Based on no action letters of the staff of the Securities and Exchange Commission issued to third parties, we believe that new notes may be offered for resale, resold and otherwise transferred by you without further compliance with the registration and prospectus delivery provisions of the Securities Act if:
  •  you are not our “affiliate” within the meaning of Rule 405 under the Securities Act;
 
  •  the new notes are acquired in the ordinary course of your business; and
 
  •  you do not intend to participate in the distribution of the new notes.
      The staff of the Securities and Exchange Commission, however, has not considered the exchange offer for the new notes in the context of a no action letter, and the staff of the Securities and Exchange Commission may not make a similar determination as in the no action letters issued to these third parties.
      If you tender in the exchange offer with the intention of participating in any manner in a distribution of the new notes:
  •  you cannot rely on such interpretations by the Securities and Exchange Commission staff issued to third parties; and
 
  •  you must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a secondary resale transaction.
      Unless an exemption from registration is otherwise available, any security holder intending to distribute new notes should be covered by an effective registration statement under the Securities Act. This registration statement and the prospectus should contain the selling security holder’s information required by Item 507 of Regulation S-K under the Securities Act. This prospectus may be used for an offer to resell, resale or other retransfer of new notes only as specifically described in this prospectus. Only broker-dealers that acquired the old notes as a result of market-making activities or other trading activities may participate in the exchange offer. Each broker-dealer that receives new notes for its own account in exchange for old notes, where such old notes were acquired by such broker-dealer as a result of market-making activities or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of the new notes. Please read the section captioned “Plan of Distribution” for more details regarding the transfer of new notes.
Terms of the Exchange Offer
      Subject to the terms and conditions described in this prospectus and in the letter of transmittal, we will accept for exchange any old notes properly tendered and not withdrawn prior to the expiration date. We will issue new notes in principal amount equal to the principal amount of old notes surrendered under the exchange offer. Old notes may be tendered only for new notes and only in integral multiples of $1,000.
      The exchange offer is not conditioned upon any minimum aggregate principal amount of old notes being tendered for exchange.
      As of the date of this prospectus, $150 million aggregate principal amount of the old notes is outstanding. This prospectus and the letter of transmittal are being sent to all registered holders of old notes. There will be

18


Table of Contents

no fixed record date for determining registered holders of old notes entitled to participate in the exchange offer.
      We intend to conduct the exchange offer in accordance with the provisions of the registration rights agreement, the applicable requirements of the Securities Act and the Securities Exchange Act of 1934 and the rules and regulations of the Securities and Exchange Commission. Old notes that the holders thereof do not tender for exchange in the exchange offer will remain outstanding and continue to accrue interest. These old notes will be entitled to the rights and benefits such holders have under the Indenture relating to the old notes and the registration rights agreement.
      We will be deemed to have accepted for exchange properly tendered old notes when we have given oral or written notice of the acceptance to the exchange agent and complied with the applicable provisions of the registration rights agreement. The exchange agent will act as agent for the tendering holders for the purposes of receiving the new notes from us.
      If you tender old notes in the exchange offer, you will not be required to pay brokerage commissions or fees or, subject to the letter of transmittal, transfer taxes with respect to the exchange of old notes. We will pay all charges and expenses, other than certain applicable taxes described below, in connection with the exchange offer. It is important that you read the section labeled “— Fees and Expenses” for more details regarding fees and expenses incurred in the exchange offer.
      We will return any old notes that we do not accept for exchange for any reason without expense to their tendering holder promptly after the expiration or termination of the exchange offer.
      Each broker-dealer that receives new notes for its own account in exchange for old notes, where such old notes were acquired by such broker-dealer as a result of market-making activities or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of such new notes. See “Plan of Distribution.” Any broker-dealer who acquired the old notes directly from us and holds old notes that have, or are reasonably likely to have, the status of unsold allotments in an initial distribution will not receive new notes in the Exchange Offer, but rather will receive new notes privately issued in exchange for such old notes.
Expiration Date
      The exchange offer will expire at 5:00 p.m., New York City time, on May 19, 2005 unless, in our sole discretion, we extend it.
Extensions, Delays in Acceptance, Termination or Amendment
      We expressly reserve the right, at any time or various times, to extend the period of time during which the exchange offer is open. We may delay acceptance of any old notes by giving oral or written notice of such extension to their holders if the exchange offer is so extended. During any such extensions, all old notes previously tendered will remain subject to the exchange offer, and we may accept them for exchange upon the expiration of the extended exchange offer.
      In order to extend the exchange offer, we will notify the exchange agent orally or in writing of any extension. We will notify the registered holders of old notes of the extension no later than 9:00 a.m., New York City time, on the business day after the previously scheduled expiration date.
      If any of the conditions described below under “— Conditions to the Exchange Offer” have not been satisfied, we reserve the right, in our sole discretion
  •  to delay accepting for exchange any old notes,
 
  •  to extend the exchange offer, or
 
  •  to terminate the exchange offer,
by giving oral or written notice of such delay, extension or termination to the exchange agent. However, we may not delay acceptance for exchange of any old notes after the expiration of the exchange offer. Subject to

19


Table of Contents

the terms of the registration rights agreement, we also reserve the right to amend the terms of the exchange offer in any manner.
      Any such delay in acceptance, extension, termination or amendment will be followed promptly by oral or written notice thereof to the registered holders of old notes. If we amend the exchange offer in a manner that we determine to constitute a material change, we will promptly disclose such amendment by means of a prospectus supplement. The supplement will be distributed to the registered holders of the old notes. Depending upon the significance of the amendment and the manner of disclosure to the registered holders, we will extend the exchange offer if the exchange offer would otherwise expire during such period.
Conditions to the Exchange Offer
      We will not be required to accept for exchange, or exchange any new notes for, any old notes if the exchange offer, or the making of any exchange by a holder of old notes, would violate applicable law or any applicable interpretation of the staff of the Securities and Exchange Commission. Similarly, we may terminate the exchange offer as provided in this prospectus before accepting old notes for exchange in the event of such a potential violation.
      In addition, we will not be obligated to accept for exchange the old notes of any holder that has not made to us the representations described under “— Purpose and Effect of the Exchange Offer,” “— Procedures for Tendering” and “Plan of Distribution” and such other representations as may be reasonably necessary under applicable Securities and Exchange Commission rules, regulations or staff interpretations to allow us to use an appropriate form to register the new notes under the Securities Act.
      We expressly reserve the right to amend or terminate the exchange offer, and to reject for exchange any old notes not previously accepted for exchange, upon the occurrence of any of the conditions to the exchange offer specified above. We will give oral or written notice of any extension, amendment, non-acceptance or termination to the holders of the old notes as promptly as practicable.
      These conditions are for our sole benefit, and we may assert them or waive them in whole or in part at any time prior to or on the expiration of the offer in our sole discretion. If we fail at any time to exercise any of these rights, this failure will not mean that we have waived our rights. Each such right will be deemed an ongoing right that we may assert at any time prior to or on the expiration of the offer.
      In addition, we will not accept for exchange any old notes tendered, and will not issue new notes in exchange for any such old notes, if at such time any stop order has been threatened or is in effect with respect to the registration statement of which this prospectus constitutes a part or the qualification of the Indenture relating to the new notes under the Trust Indenture Act of 1939.
Procedures for Tendering
How to tender generally
      To participate in the exchange offer, you must properly tender your old notes to the exchange agent as described below. We will only issue new notes in exchange for old notes that you timely and properly tender. Therefore, you should allow sufficient time to ensure timely delivery of the old notes, and you should follow carefully the instructions on how to tender your old notes. It is your responsibility to properly tender your old notes. We have the right to waive any defects. However, we are not required to waive defects, and neither we nor the exchange agent is required to notify you of defects in your tender.
      If you have any questions or need help in exchanging your old notes, please call the exchange agent whose address and phone number are described in the letter of transmittal.
      All of the old notes were issued in book-entry form, and all of the old notes are currently represented by a global certificate held by Cede & Co. for the account of DTC. We have confirmed with DTC that the old notes may be tendered using ATOP. The exchange agent will establish an account with DTC for purposes of the exchange offer promptly after the commencement of the exchange offer, and DTC participants may electronically transmit their acceptance of the exchange offer by causing DTC to transfer their old notes to the

20


Table of Contents

exchange agent using the ATOP procedures. In connection with the transfer, DTC will send an “agent’s message” to the exchange agent. The agent’s message will state that DTC has received instructions from the participant to tender old notes and that the participant agrees to be bound by the terms of the letter of transmittal.
      By using the ATOP procedures to exchange old notes, you will not be required to deliver a letter of transmittal to the exchange agent. However, you will be bound by its terms just as if you had signed it.
      There is no procedure for guaranteed late delivery of the old notes.
Determinations under the exchange offer
      We will determine in our sole discretion all questions as to the validity, form, eligibility, time of receipt, acceptance of tendered old notes and withdrawal of tendered old notes. Our determinations will be final and binding. We reserve the absolute right to reject any old notes not properly tendered or any old notes our acceptance of which would, in the opinion of our counsel, be unlawful. We also reserve the rights to waive any defects, irregularities or conditions of tender as to particular old notes. Our interpretation of the terms and conditions of the exchange offer, including the instructions in the letter of transmittal, will be final and binding on all parties. Unless waived, all defects or irregularities in connection with tenders of old notes must be cured within such time as we shall determine. Although we intend to notify holders of defects or irregularities with respect to tenders of old notes, neither we, the exchange agent nor any other person will incur any liability for failure to give such notification. Tenders of old notes will not be deemed made until such defects or irregularities have been cured or waived. Any old notes received by the exchange agent that are not properly tendered and as to which the defects or irregularities have not been cured or waived will be returned to the tendering holder as soon as practicable following the expiration date.
When we will issue new notes
      In all cases, we will issue new notes for old notes that we have accepted for exchange under the exchange offer only after the exchange agent timely receives:
  •  a book-entry confirmation of such old notes into the exchange agent’s account at DTC; and
 
  •  a properly transmitted agent’s message.
Return of old notes not accepted or exchanged
      If we do not accept any tendered old notes for exchange or if old notes are submitted for a greater principal amount than the holder desires to exchange, the unaccepted or non-exchanged old notes will be returned without expense to their tendering holder. Such non-exchanged old notes will be credited to an account maintained with DTC. These actions will occur promptly after the expiration or termination of the exchange offer.
Your representations to us
      By agreeing to be bound by the letter of transmittal, you will represent to us that, among other things:
  •  any new notes that you receive will be acquired in the ordinary course of your business;
 
  •  you have no arrangement or understanding with any person or entity to participate in the distribution of the new notes within the meaning of the Securities Act;
 
  •  if you are not a broker-dealer that you are not engaged in and do not intend to engage in the distribution of the new notes;
 
  •  if you are a broker-dealer that will receive new notes for your own account in exchange for old notes, you acquired those notes as a result of market-making activities or other trading activities and you will deliver a prospectus, as required by law, in connection with any resale of such new notes; and

21


Table of Contents

  •  you are not our “affiliate,” as defined in Rule 405 of the Securities Act.
Withdrawal of Tenders
      Except as otherwise provided in this prospectus, you may withdraw your tender at any time prior to the expiration date. For a withdrawal to be effective you must comply with the appropriate ATOP procedures. Any notice of withdrawal must specify the name and number of the account at DTC to be credited with withdrawn old notes and otherwise comply with the ATOP procedures.
      We will determine all questions as to the validity, form, eligibility and time of receipt of notice of withdrawal. Our determination shall be final and binding on all parties. We will deem any old notes so withdrawn not to have been validly tendered for exchange for purposes of the exchange offer.
      Any old notes that have been tendered for exchange but that are not exchanged for any reason will be credited to an account maintained with DTC for the old notes. This crediting will take place as soon as practicable after withdrawal, rejection of tender or termination of the exchange offer. You may retender properly withdrawn old notes by following the procedures described under “— Procedures for Tendering” above at any time on or prior to the expiration date.
Fees and Expenses
      We will bear the expenses of soliciting tenders. The principal solicitation is being made by mail; however, we may make additional solicitation by telegraph, telephone or in person by our officers and regular employees and those of our affiliates.
      We have not retained any dealer-manager in connection with the exchange offer and will not make any payments to broker-dealers or others soliciting acceptances of the exchange offer. We will, however, pay the exchange agent reasonable and customary fees for its services and reimburse it for its related reasonable out-of-pocket expenses.
      We will pay the cash expenses to be incurred in connection with the exchange offer. They include:
  •  Securities and Exchange Commission registration fees;
 
  •  fees and expenses of the exchange agent and trustee;
 
  •  accounting and legal fees and printing costs; and
 
  •  related fees and expenses.
Transfer Taxes
      We will pay all transfer taxes, if any, applicable to the exchange of old notes under the exchange offer. The tendering holder, however, will be required to pay any transfer taxes, whether imposed on the registered holder or any other person, if a transfer tax is imposed for any reason other than the exchange of old notes under the exchange offer.
Consequences of Failure to Exchange
      If you do not exchange new notes for your old notes under the exchange offer, you will remain subject to the existing restrictions on transfer of the old notes. In general, you may not offer or sell the old notes unless they are registered under the Securities Act or unless the offer or sale is exempt from the registration under the Securities Act and applicable state securities laws. Except as required by the registration rights agreement, we do not intend to register resales of the old notes under the Securities Act.
Accounting Treatment
      We will record the new notes in our accounting records at the same carrying value as the old notes. This carrying value is the aggregate principal amount of the old notes, as reflected in our accounting records on the

22


Table of Contents

date of exchange. Accordingly, we will not recognize any gain or loss for accounting purposes in connection with the exchange offer. The expenses of the exchange offer will be amortized over the term of the new notes.
Other
      Participation in the exchange offer is voluntary, and you should carefully consider whether to accept. You are urged to consult your financial and tax advisors in making your own decision on what action to take.
      We may in the future seek to acquire untendered old notes in open market or privately negotiated transactions, through subsequent exchange offers or otherwise. We have no present plans to acquire any old notes that are not tendered in the exchange offer or to file a registration statement to permit resales of any untendered old notes.
      Each broker-dealer that receives new notes for its own account in exchange for old notes, where such old notes were acquired by such broker-dealer as a result of market-making activities or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of such new notes. See “Plan of Distribution.”

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

DESCRIPTION OF THE NEW NOTES
General
      The form and terms of the new notes are the same as the form and terms of the old notes, except that the offer and exchange of the new notes have been registered under the Securities Act, and the new notes will not bear legends restricting the transfer thereof, will not be entitled to registration rights under the registration rights agreement, and will not contain provisions relating to additional interest. Range Resources Corporation will issue the new notes under an Indenture among itself, the Subsidiary Guarantors and J.P. Morgan Trust Company, National Association, as trustee. The terms of the new notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939.
      Certain terms used in this description are defined under the subheading “— Certain Definitions.” In this description, the words “Range Resources” or the “Company” refer only to Range Resources Corporation, and any successor obligor on the notes, and not to any of its subsidiaries. As used in this section, the term “notes” refers to both old notes and new notes.
      The old notes and the new notes will constitute a single class of debt securities under the Indenture. If the exchange offer is consummated, holders of old notes who do not exchange new notes for their old notes will vote together with holders of the new notes for all relevant purposes under the Indenture. Accordingly, in determining whether the required holders have given any notice, consent or waiver or taken any other action permitted under the Indenture, any old notes that remain outstanding after the exchange offer will be aggregated the new notes and the holders of the old notes and the new notes will vote together as a single class. All references in this prospectus to specified percentages in aggregate principal amount of the notes that are outstanding means, at any time after the exchange is consummated, the percentage in aggregate principal amount of the old notes and the new notes then outstanding.
      The following description is a summary of the provisions of the Indenture that we believe to be material and of interest to you and does not restate that agreement in its entirety. We encourage you to read the Indenture because that agreement, and not this description, will define your rights as a holder of the new notes. A copy of the Indenture is filed as an exhibit to our Current Report on Form 8-K filed with the Securities Exchange Commission on March 15, 2005, and is incorporated by reference as an exhibit hereto.
Basic Terms of the Notes
      The notes
  •  are unsecured senior subordinated obligations of Range Resources, subordinated in right of payment to all existing and future Senior Debt of Range Resources in accordance with the subordination provisions of the Indenture;
 
  •  are jointly, severally and unconditionally guaranteed on a senior subordinated basis by each of the Restricted Subsidiaries of the Company and any future Restricted Subsidiary of the Company. The obligations of the Subsidiary Guarantors under the Guarantees will be general unsecured obligations of each of the Subsidiary Guarantors and will be subordinated in right of payment to all obligations of the Subsidiary Guarantors in respect of Senior Debt;
 
  •  are issued as new notes under the Indenture in an original aggregate principal amount of $150 million;
 
  •  mature on March 15, 2015;
 
  •  bear interest commencing the date of issue at 63/8%, payable semiannually in arrears on each March 15 and September 15, commencing September 15, 2005 to holders of record on the March 1 or September 1 immediately preceding the interest payment date; and
 
  •  bear interest on overdue principal, and, to the extent lawful, pay interest on overdue interest, at 1.0% per annum higher than 63/8%.
      Interest will be computed on the basis of a 360-day year of twelve 30-day months.

Table of Contents

Additional Notes
      Subject to the covenants described below, the Company may issue additional notes under the Indenture having the same terms in all respects as the notes except that interest will accrue on the additional notes from their date of issuance.
      Any old notes not exchanged in the exchange offer, any new notes and any additional notes would be treated as a single class for all purposes under the Indenture and will vote together as one class on all matters under the Indenture.
Optional Redemption
      Except as otherwise described below, the new notes will not be redeemable at the Company’s option prior to March 15, 2010. Thereafter, the new notes will be subject to redemption at the option of the Company, in whole or in part, upon not less than 30 nor more than 60 days’ notice, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest thereon to the applicable redemption date, if redeemed during the twelve-month period beginning on July 15 of the years indicated below:
         
    % of Principal
Year   Amount
     
2010
    103.188 %
2011
    102.125 %
2012
    101.063 %
2013 and thereafter
    100.000 %
      Prior to March 15, 2008, the Company may, at its option, on any one or more occasions, redeem up to 35% of the original aggregate principal amount of the new notes at a redemption price equal to 106.375% of the principal amount thereof, plus accrued and unpaid interest, if any, thereon to the redemption date, with all or a portion of the net proceeds of public sales of Equity Interests of the Company; provided that at least 65% of the original aggregate principal amount of the new notes remains outstanding immediately after the occurrence of such redemption; and provided, further, that such redemption shall occur within 60 days of the date of the closing of the related sale of such Equity Interests.
No Mandatory Redemption or Sinking Fund
      Except as set forth below under “— Repurchase at the Option of Holders,” the Company is not required to make mandatory redemption or sinking fund payments with respect to the new notes.
Guarantees
      The Company’s payment obligations under the new notes will be jointly, severally and unconditionally guaranteed (the “Guarantees”) by each Restricted Subsidiary of the Company and any future Restricted Subsidiary of the Company. The Subsidiary Guarantors shall initially be Range Energy I, Inc., Range HoldCo, Inc., Range Production Company, Range Energy Ventures Corporation, Gulfstar Energy, Inc., Range Energy Finance Corporation, RB Operating Company 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

26


Table of Contents

formed by or surviving any such consolidation or merger (if other than such Subsidiary Guarantor) assumes all the obligations of such Subsidiary Guarantor pursuant to a supplemental Indenture in form and substance reasonably satisfactory to the Trustee in respect of the notes, the Indenture and the Guarantees; (ii) immediately after giving effect to such transaction, no Default or Event of Default exists; and (iii) such transaction does not violate any of the covenants described under the heading “— Certain Covenants.”
      The Indenture provides that in the event of a sale or other disposition of all or substantially all of the assets of a Subsidiary Guarantor to a third party or an Unrestricted Subsidiary in a transaction that does not violate any of the covenants in the Indenture, by way of merger, consolidation or otherwise, or a sale or other disposition of all of the capital stock of a Subsidiary Guarantor, then such Subsidiary Guarantor (in the event of a sale or other disposition, by way of such a merger, consolidation or otherwise, of all of the capital stock of such Subsidiary Guarantor) or the Person acquiring the property (in the event of a sale or other disposition of all or substantially all of the assets of such Subsidiary Guarantor) will be released from and relieved of any obligations under its Guarantee; provided that the Net Proceeds of such sale or other disposition are applied in accordance with the covenant described under the caption “— Repurchase at the Option of Holders — Asset sales.”
      Any Subsidiary Guarantor that is designated an Unrestricted Subsidiary in accordance with the terms of the Indenture shall be released and relieved of its obligations under its Guarantee and any Unrestricted Subsidiary and any newly formed or newly acquired Subsidiary that becomes a Restricted Subsidiary will be required to execute a Guarantee in accordance with the terms of the Indenture.
      The Company is a holding company, owns no operating assets and has no significant operations independent of its subsidiaries. The Guarantees are full and unconditional and joint and several, and any subsidiaries of the Company other than the Subsidiary Guarantors are either minor subsidiaries or indirect subsidiaries, or both.
Subordination
      The payment of principal of, premium, if any, and interest on the notes and any other payment obligations of the Company in respect of the notes (including any obligation to repurchase the notes) will be subordinated in certain circumstances in right of payment, as set forth in the Indenture, to the prior payment in full in cash of all Senior Debt, whether outstanding on the date of the Indenture or thereafter incurred.
      Upon any payment or distribution of property or securities to creditors of the Company in a liquidation or dissolution of the Company or in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to the Company or its property, or in an assignment for the benefit of creditors or any marshalling of the Company’s assets and liabilities, the holders of Senior Debt will be entitled to receive payment in full of all Obligations due in respect of such Senior Debt (including interest after the commencement of any such proceeding at the rate specified in the applicable Senior Debt, whether or not a claim for such interest would be allowed in such proceeding) before the Holders of notes will be entitled to receive any payment with respect to the notes, and until all Obligations with respect to Senior Debt are paid in full, any distribution to which the Holders of notes would be entitled shall be made to the holders of Senior Debt (except in each case that Holders of notes may receive securities that are subordinated at least to the same extent as the notes are subordinated to Senior Debt and any securities issued in exchange for Senior Debt and payments made from the trust described under “— Legal Defeasance and Covenant Defeasance”).
      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

27


Table of Contents

(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. As of December 31, 2004, we had $423.9 million of Senior Debt outstanding, excluding intercompany debt and trade payables. The Indenture will limit, subject to certain financial tests, the amount of additional Indebtedness, including Senior Debt, that the Company and its Subsidiaries can incur. See “— Certain Covenants — Incurrence of indebtedness and issuance of disqualified stock.”
Repurchase at the Option of Holders
Change of Control
      Upon the occurrence of a Change of Control, each Holder of notes will have the right to require the Company to repurchase all or any part (equal to $1,000 or an integral multiple thereof) of such Holder’s notes pursuant to the offer described below (the “Change of Control Offer”) at an offer price in cash equal to 101% of the aggregate principal amount of the notes plus accrued and unpaid interest, if any, thereon to the date of purchase (the “Change of Control Payment”). Within 30 days following any Change of Control, the Company will mail a notice to each Holder describing the transaction or transactions that constitute the Change of Control and offer to repurchase the notes pursuant to the procedures required by the Indenture and described in such notice. The Change of Control Payment shall be made on a business day not less than 30 days nor more than 60 days after such notice is mailed (the “Change of Control Payment Date”). The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of the notes as a result of a Change of Control.
      On the Change of Control Payment Date, the Company will, to the extent lawful, (i) accept for payment all the notes or portions thereof properly tendered pursuant to the Change of Control Offer, (ii) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all the notes or portions thereof so tendered and (iii) deliver or cause to be delivered to the Trustee the notes so accepted together with an Officers’ Certificate stating the aggregate principal amount of such notes or portions thereof being purchased by the Company. The Paying Agent will promptly mail to each Holder of 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

28


Table of Contents

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) are assumed by the transferee of any such assets pursuant to a customary novation agreement that releases the Company or such Restricted Subsidiary from further liability.
      Within 360 days after the receipt of any Net Proceeds from an Asset Sale, the Company may apply such Net Proceeds, at its option, (a) to reduce Senior Debt, (b) to acquire a controlling interest in another Oil and Gas Business, (c) to make capital expenditures in respect of the Company’s or its 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 PassuIndebtedness (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 or other Affiliate of the Company that is not a Wholly Owned Restricted Subsidiary of the Company; (iii) make any principal payment on, or purchase, redeem, defease or otherwise acquire or retire for value any Indebtedness that is subordinated to the notes, except at final maturity; or (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

30


Table of Contents

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 March 9, 2005 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) 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)(ii) of the preceding paragraph; (3) the defeasance, redemption or repurchase of Subordinated Indebtedness with the net cash proceeds from an incurrence of subordinated Permitted Refinancing Debt or the substantially concurrent sale (other than to a Subsidiary of the Company) of Equity Interests of the Company (other than Disqualified Stock); provided that the amount of any such net cash proceeds that are utilized for any such redemption, repurchase, retirement or other acquisition shall be excluded from clause (c)(ii) of the preceding paragraph; (4) the repurchase, redemption or other acquisition or retirement for value of any Equity Interests of the Company or any Subsidiary of the Company held by any of the Company’s (or any of its Subsidiaries’) employees pursuant to any management equity subscription agreement or stock option agreement in effect as of the date of the Indenture; provided that the aggregate price paid for all such repurchased, redeemed, acquired or retired Equity Interests shall not exceed $2 million in any twelve-month period; and provided further that no Default or Event of Default shall have occurred and be continuing immediately after such transaction; (5) repurchases of Equity Interests deemed to occur upon exercise of stock options if such Equity Interests represent a portion of the exercise price of such options; 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.
      The amount of all Restricted Payments (other than cash) shall be the fair market value (as determined in good faith by a resolution of the Board of Directors set forth in an Officers’ Certificate delivered to the Trustee, which determination shall be conclusive evidence of compliance with this provision) on the date of the Restricted Payment of the asset(s) proposed to be transferred by the Company or the applicable Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment. Not later than five days after the date of making any Restricted Payment, the Company shall deliver to the Trustee an Officers’ Certificate stating that such Restricted Payment is permitted and setting forth the basis upon which the calculations required by the covenant “Restricted Payments” were computed.
Designation of unrestricted subsidiaries
      The Board of Directors of the Company may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if such designation would not cause a Default. For purposes of making such determination, all outstanding Investments by the Company and its Restricted Subsidiaries (except to the extent repaid in cash) in the Subsidiary so designated will be deemed to be Restricted Payments at the time of such designation and will reduce the amount available for Restricted Payments under clause (c) of the first paragraph of the

31


Table of Contents

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; (b) the Indebtedness evidenced by the 73/8% 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 outstanding under all Credit Facilities does not, at any one time, exceed the greater of (i) $600.0 million (or, if there is any permanent reduction in the aggregate principal amount permitted to be borrowed under the Credit Agreement, such lesser aggregate principal amount) and (ii) an amount equal to the sum of (A) $50.0 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

32


Table of Contents

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 Indenture to be incurred (including Indebtedness previously incurred pursuant to this clause (k)); (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; (m) Indebtedness consisting of obligations in respect of purchase price adjustments, guarantees or indemnities in connection with the acquisition or disposition of assets; and (n) production imbalances that do not, at any one time outstanding, exceed 2% of the Total Assets of the Company.
      The Indenture provides that the Company will not permit any Unrestricted Subsidiary to incur any Indebtedness other than Non-Recourse Debt; provided, however, if any such Indebtedness ceases to be Non-Recourse Debt, such event shall be deemed to constitute an incurrence of Indebtedness by the Company.
No layering
      The Indenture provides that (i) the Company will not incur, create, issue, assume, guarantee or otherwise become liable for any Indebtedness that is subordinate or junior in right of payment to any Senior Debt and senior in any respect in right of payment to the notes and (ii) the Subsidiary Guarantors will not directly or indirectly incur, create, issue, assume, guarantee or otherwise become liable for any Indebtedness that is subordinate or junior in right of payment to 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 encumbrance or restriction on the ability of any Restricted Subsidiary to (i)(x) pay dividends or make any other distributions to the Company or any of its Restricted Subsidiaries (1) on its Capital Stock or (2) with respect to any other interest or participation in, or measured by, its profits, or (y) pay any indebtedness owed by it to the Company or any of its Restricted Subsidiaries, (ii) make loans or advances to the Company or any of its Restricted Subsidiaries or (iii) transfer any of its properties or assets to the Company or any of its Restricted Subsidiaries, except for such encumbrances or restrictions existing under or by reason of (a) the Credit Agreement as in effect as of the date of the Indenture, and any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings thereof or any other Credit Facility, provided that such amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements, refinancings or other Credit Facilities are no more restrictive taken as a whole with respect to such dividend and other payment restrictions than those contained in the Credit Agreement as in effect on the date of the Indenture, (b) the Indenture and the notes, (c) applicable law, (d) any instrument governing Indebtedness or Capital Stock of a Person acquired by the Company or any of its Restricted Subsidiaries as in effect at the time of such acquisition (except, in the case of Indebtedness, to the extent such Indebtedness was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not

33


Table of Contents

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 no more restrictive than those contained in the agreements governing the Indebtedness being refinanced.
Merger, consolidation or 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; (iv) immediately after giving effect to such transaction or a series of transactions on a pro forma basis (and treating any Indebtedness not previously an obligation of the Company and its Subsidiaries which becomes the obligation of the Company or any of its Subsidiaries as a result of such transaction or series of transactions as having been incurred at the time of such transaction or series of transactions), the Consolidated Net Worth of the Company and its Subsidiaries or the Surviving Entity (if the Company is not the continuing obligor under the Indenture) is equal to or greater than the Consolidated Net Worth of the Company and its Subsidiaries immediately prior to such transaction or series of transactions and (v) the Company or the Surviving Entity (if the Company is not the continuing obligor under the Indenture) will, at the time of such transaction or series of transactions and after giving pro forma effect thereto as if such transaction or series of transactions had occurred at the beginning of the applicable four-quarter period, be permitted to incur at least $1.00 of additional Indebtedness pursuant to the test set forth in the first paragraph of the covenant described above under the caption “— Incurrence of indebtedness and issuance of disqualified stock.” Notwithstanding the restrictions described in the foregoing clauses (iv) and (v), any Restricted Subsidiary may consolidate with, merge into or transfer all or part of its properties and assets to the Company, and any Wholly Owned Restricted Subsidiary may consolidate with, merge into or transfer all or part of its properties and assets to another Wholly Owned Restricted Subsidiary.
Transactions with affiliates
      The Indenture provides that the Company will not, and will not permit any of its Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any of its Affiliates (each of the foregoing, an “Affiliate Transaction”), unless (i) such Affiliate Transaction is on terms that are no less favorable to the Company or the relevant Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Subsidiary with an unrelated Person and (ii) the Company delivers to the Trustee (a) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of

34


Table of Contents

$1.0 million but less than or equal to $5.0 million, an Officers’ Certificate certifying that such Affiliate Transaction complies with clause (i) above, (b) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $5.0 million but less than or equal to $10.0 million, a resolution of the Board of Directors set forth in an Officers’ Certificate certifying that such Affiliate Transaction or series of Affiliate Transactions complies with clause (i) above and that such Affiliate Transaction or series of Affiliate Transactions has been approved in good faith by a majority of the members of the Board of Directors who are disinterested with respect to such Affiliate Transaction or series of related Affiliate Transactions, which resolution shall be conclusive evidence of compliance with this provision, and (c) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $10.0 million, 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 and consistent with the past practice of the Company or such Subsidiary, (2) transactions between or among the Company and/or its Restricted Subsidiaries, (3) Restricted Payments and Permitted Investments that are permitted by the provisions of the Indenture described above under the caption “— Restricted payments,” and (4) indemnification payments made to officers, directors and employees of the Company or any Subsidiary pursuant to charter, bylaw, statutory or contractual provisions.
Additional subsidiary guarantees
      The Indenture provides that if the Company or any of its Subsidiaries shall acquire or create another Restricted Subsidiary after the date of the Indenture, then such newly acquired or created Restricted Subsidiary will be required to execute a 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.
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 (including any interest payable as liquidated damages), if any, 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. 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.

However, no amendment may be made to the subordination provisions of the Indenture that adversely affects the rights of any holder of Senior Debt then outstanding unless the holders of such Senior Debt (or any group or representative thereof authorized to give a consent) consents to such change.
      Notwithstanding the foregoing, without the consent of any Holder of the notes the Company and the Trustee may amend or supplement the Indenture or the notes to cure any ambiguity, defect or inconsistency, to provide for uncertificated notes in addition to or in place of certificated notes, to provide for the assumption of the Company’s obligations to Holders of the notes in the case of a merger or consolidation, to make any change that would provide any additional rights or benefits to the Holders of the notes or that does not adversely affect the legal rights under the Indenture of any such Holder, to secure the notes or to comply with requirements of the Commission in order to effect or maintain the qualification of the Indenture under the Trust Indenture Act.
Legal defeasance and covenant defeasance

In addition, the Company may, at its option and at any time, elect to have the obligations of the Company released with respect to certain covenants that are described in the Indenture (“Covenant Defeasance”) and thereafter any omission to comply with such obligations shall not constitute a Default or Event of Default. In the event Covenant Defeasance occurs, certain events (not including non-payment, bankruptcy, receivership, rehabilitation and insolvency events) described under “Events of default and remedies” will no longer constitute an Event of Default.
      In order to exercise either Legal Defeasance or Covenant Defeasance, (i) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of notes, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, premium, if any, and interest on the outstanding notes on the stated maturity or on the applicable redemption date, as the case may be, and the Company must specify whether the notes are being defeased to maturity or to a particular redemption date; (ii) in the case of Legal Defeasance, the Company shall have delivered to the Trustee an opinion of counsel in the United States reasonably acceptable to such Trustee confirming that (A) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (B) since the date of the Indenture, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such opinion of counsel shall confirm that, the Holders of the outstanding notes will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred; (iii) in the case of Covenant Defeasance, the Company shall have delivered to the Trustee an opinion of counsel in the United States reasonably acceptable to such Trustee confirming that the Holders of the outstanding notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; (iv) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit) or insofar as Events of Default from bankruptcy or insolvency events are concerned, at any time in the period ending on the 91st day after the date of deposit; (v) such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under any material agreement or instrument (other than the Indenture) to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound; (vi) the Company must have delivered to the Trustee an opinion of counsel to the effect that after the 91st day following the deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally; (vii) the Company must deliver to the Trustee an Officers’ Certificate stating that the deposit was not made by the Company with the intent of preferring the Holders of notes over the other creditors of the Company, or with the intent of defeating, hindering, delaying or defrauding creditors of the Company or others; and (viii) the Company must deliver to the Trustee an Officers’ Certificate and an opinion of counsel, each stating that all conditions precedent provided for relating to the Legal Defeasance or the Covenant Defeasance have been complied with.

Table of Contents

Company or any Restricted Subsidiary with terms substantially less favorable to the Company than those that might have been obtained from Persons who are not Affiliates of the Company.

      “Wholly Owned Restricted Subsidiary” of any Person means a Restricted Subsidiary of such Person all of the outstanding Capital Stock or other ownership interests of which (other than directors’ qualifying shares) shall at the time be owned, directly or indirectly, by such Person or by one or more Wholly Owned Restricted Subsidiaries of such Person.
Form, Denomination and Registration of the Notes
      The new notes will be issued in registered form, without interest coupons, in denominations of $1,000 and integral multiples thereof, in the form of both global notes and certificated notes, as further provided below.
      The trustee is not required (i) to issue, register the transfer of or exchange any note for a period of 15 days before a selection of notes to be redeemed or repurchased, (ii) to register the transfer of or exchange any note so selected for redemption or repurchase in whole or in part, except, in the case of a partial redemption or repurchase, that portion of any note not being redeemed or repurchased, or (iii) if a redemption or a repurchase is to occur after a regular record date but on or before the corresponding interest payment date, to register the transfer or exchange of any note on or after the regular record date and before the date of redemption or repurchase. See “— Global Notes” and “— Certificated Notes” for a description of additional transfer restrictions applicable to the notes.
      No service charge will be imposed in connection with any transfer or exchange of any note, but the Company may in general require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith.
Global Notes
      Global notes representing the new notes will be deposited with a custodian for DTC, and registered in the name of a nominee of DTC. Beneficial interests in the global notes will be shown on records maintained by DTC and its direct and indirect participants. So long as DTC or its nominee is the registered owner or holder of a global note, DTC or such nominee will be considered the sole owner or holder of the notes represented by such global note for all purposes under the Indenture and the notes. No owner of a beneficial interest in a

49


Table of Contents

global note will be able to transfer such interest except in accordance with DTC’s applicable procedures and the applicable procedures of its direct and indirect participants.
      The Company will apply to DTC for acceptance of the global notes in its book-entry settlement system. Investors may hold their beneficial interests in the global notes directly through DTC if they are participants in DTC, or indirectly through organizations which are participants in DTC.
      Payments of principal and interest under each global note will be made to DTC’s nominee as the registered owner of such global note. The Company expects that the nominee, upon receipt of any such payment, will immediately credit DTC participants’ accounts with payments proportional to their respective beneficial interests in the principal amount of the relevant global note as shown on the records of DTC. The Company also expects that payments by DTC participants to owners of beneficial interests will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers registered in the names of nominees for such customers. Such payments will be the responsibility of such participants, and none of the Company, the Trustee, the custodian or any paying agent or registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial interests in any global note or for maintaining or reviewing any records relating to such beneficial interests.
Certificated Notes
      If DTC notifies the Company that it is unwilling or unable to continue as depositary for a global note and a successor depositary is not appointed by the Company within 90 days of such notice, or an Event of Default has occurred and the trustee has received a request from DTC, the trustee will exchange each beneficial interest in that global note for one or more certificated notes registered in the name of the owner of such beneficial interest, as identified by DTC. Neither the Company nor the trustee will be liable for any delay by DTC or any participant or indirect participant in DTC in identifying the beneficial owners of the related notes and each of those person may conclusively rely on, and will be protected in relying on, instructions from DTC for all purposes, including with respect to the registration and delivery, and the respective principal amounts, of the notes to be issued.
Same Day Settlement and Payment
      The Indenture requires that payments in respect of the notes represented by the global notes be made by wire transfer of immediately available funds to the accounts specified by holders of the global notes. With respect to notes in certificated form, the Company will make all payments by wire transfer of immediately available funds to the accounts specified by the holders thereof or, if no such account is specified, by mailing a check to each holder’s registered address.
      The new notes represented by the global notes are expected to trade in DTC’s Same-Day Funds Settlement System, and any permitted secondary market trading activity in such notes will, therefore, be required by DTC to be settled in immediately available funds. The Company expects that secondary trading in any certificated notes will also be settled in immediately available funds.

UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS
      The following discussion is a summary of the material federal income tax considerations relevant to the exchange of new notes for old notes but does not purport to be a complete analysis of all potential tax effects. This discussion is based upon the provisions of the Internal Revenue Code of 1986, as amended, applicable Treasury Regulations promulgated and proposed thereunder, judicial authority and administrative interpretations, as of the date hereof, all of which are subject to change, possibly with retroactive effect or are subject to different interpretations. This discussion does not address the tax considerations arising under the laws of any foreign, state, local, or other jurisdiction.
      We believe that the exchange of new notes for old notes should not be an exchange or otherwise a taxable event to a holder for United States federal income tax purposes. Accordingly, a holder should have the same adjusted issue price, adjusted basis and holding period in the new notes as it had in the old notes immediately before the exchange.

51


Table of Contents

PLAN OF DISTRIBUTION
      Based on interpretations by the staff of the Securities and Exchange Commission in no action letters issued to third parties, we believe that you may transfer new notes issued in the exchange offer in exchange for the old notes if:
  •  you acquire the new notes in the ordinary course of your business; and
 
  •  you are not engaged in, and do not intend to engage in, and have no arrangement or understanding with any person to participate in, a distribution of the new notes.
      Each broker-dealer that receives new notes for its own account pursuant to the exchange offer must acknowledge that it will deliver a prospectus in connection with any resale of such new notes. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of new notes received in exchange for old notes where such old notes were acquired as a result of market-making activities or other trading activities. We and the subsidiary guarantors have agreed that, starting on the expiration date of the exchange offer and ending on the close of business 180 days after the date of such expiration date, we will make this prospectus, as amended or supplemented, available to any broker-dealer for use in connection with any such resale.
      If you wish to exchange new notes for your old notes in the exchange offer, you will be required to make representations to us as described in “Exchange Offer — Purpose and Effect of the Exchange Offer” and “— Procedures for Tendering — Your representations to us” in this prospectus and in the letter of transmittal. In addition, if you are a broker-dealer who receives new notes for your own account in exchange for old notes that were acquired by you as a result of market-making activities or other trading activities, you will be required to acknowledge that you will deliver a prospectus in connection with any resale by you of the new notes.
      We will not receive any proceeds from any resale of new notes by broker-dealers. New notes received by broker-dealers for their own account pursuant to the exchange offer may be sold from time to time in one or more transactions in the over-the-counter market, in negotiated transactions, through the writing of options on the new notes or a combination of such methods of resale, at market prices prevailing at the time of resale, at prices related to such prevailing market prices or negotiated prices. Any such resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commission or concessions from any such broker-dealer and/or the purchasers of any such new notes. Any broker-dealer that resells new notes that were received by it for its own account pursuant to the exchange offer and any broker or dealer that participates in a distribution of such new notes may be deemed to be an “underwriter” within the meaning of the Securities Act, and any profit on any such resale of new notes and any commission or concessions received by any such persons may be deemed to be underwriting compensation under the Securities Act. The letter of transmittal states that by acknowledging that it will deliver and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act.
      For a period of 180 days after the expiration date of the exchange offer, we and the subsidiary guarantors will promptly send additional copies of this prospectus and any amendment or supplement to this prospectus to any broker-dealer that requests such documents in the letter of transmittal. We have agreed to pay all expenses incident to the exchange offer (including the expenses of one counsel for the holders of the old notes) other than commission or concession of any brokers or dealers and will indemnify the holders of the old notes (including any broker-dealers) against certain liabilities, including liabilities under the Securities Act.

DIRECTOR COMPENSATION
      Upon Mr. Blackburn’s election in April 2003 as the non-executive Chairman of the Board, the Board approved a retainer of $100,000 per annum for Mr. Blackburn. Such retainer is paid quarterly, one-half in cash and one-half in fully-vested restricted common stock of the Company issued at the then market value and placed in a deferred compensation account for Mr. Blackburn. No increase in Mr. Blackburn’s retainer was made in 2004.
      In September 2003, upon the recommendation of the Compensation Committee following its review of market data and other considerations, the Board approved an increase in director compensation. The Board maintained the annual grant of 8,000 stock options and retainer of $25,000 per annum for non-employee directors but initiated a meeting fee of $1,000 for each Board or Committee meeting that a director attends, including telephonic meetings.
      The meeting fees were initiated to recognize the increased time and number of meetings required for Board service with increased responsibilities under each committee’s charters, especially the Audit and Compensation Committees. The Board also approved the recommendation of the Compensation Committee to grant each director annually restricted shares of the Company’s common stock in lieu of participation in the Company’s stock purchase plan. In May 2004, upon the recommendation of the Compensation Committee, the Board approved the grant of 4,000 shares of restricted common stock to each director.

      Effective March, 2005, the Board adopted the Range Resources Corporation Executive Change in Control Severance Benefit Plan (the “Management Plan”) pursuant to which officers and certain key employees (the “Management Group”) may be entitled to receive certain payments and benefits if there is a change in control and a member of the Management Group is terminated other than for cause or resigns for good reason. All other employees (the “Employee Group”) may be entitled to receive more limited payments under the Range Resources Corporation Employee Change in Control Severance Benefit Plan (the “Employee Plan”) upon an involuntary termination of employment by the Company for other than cause. Upon a Change in Control (as defined in the plans), all nonvested equity-based compensation awards automatically vest under both plans. If any person in the Management Group is (i) terminated, other than for Cause (as defined in the plans), (A) within twelve full calendar months following a Change in Control, (B) prior to a Change in Control in anticipation of the change in control, (C) during the period beginning on the date stockholder approval is obtained for a Business Combination (as defined in the plans) which constitutes a Change in Control and ending as of the last day of the twelfth full calendar month following the consummation of the Business Combination, or (D) during the period beginning with the earlier of the public announcement or commencement of a tender or exchange offer constituting a Change in Control and ending on the last day of the twelfth full calendar month following the consummation of such transaction, unless such transaction is a Business Combination, in which case the period will end in the twelfth full calendar month following stockholder approval of the Business Combination (each such period of at least twelve months, the “Protection Period”), or (ii) terminates employment within the Protection Period due to a material diminution of the position or responsibility of the employee, or reduction in the employee’s compensation or benefits, or a substantial change in the location of the principal place of the employee’s employment, the employee will receive a lump sum payment (the “Management Payment”) equal to (i) the employee’s

“Benefit Multiple” multiplied by (ii) the sum of (a) the average of the bonuses paid or awarded to the employee for the three prior fiscal years plus (b) the employee’s base salary. The Benefit Multiple for the Named Executive Officers is: Mr. Pinkerton — three; Mr. Ventura — three; Mr. Manny — two and one-half; Mr. Waller — two; and Mr. Stephens — two.
      The Benefit Multiple for all other members of the Management Group is two for officers and one for key employees specifically named in the Plan. In addition, upon such a termination, persons in the Management Group will receive, for a period of years equal to their Benefit Multiple, continued participation in any medical, dental, life and disability insurance and any other insurance arrangement for the continued benefit of the employee (and, if applicable, the employee’s spouse and minor children) in which such persons were participating immediately prior to the earlier of the termination of employment or the date of the event constituting good reason. If any person in the Employee Group is terminated by the Company, other than for cause, within twelve months after a change in control, the employee will receive a lump sum payment (the “Employee Payment”) equal to (i) six months of their total annual base salary, plus (ii) one-half of the average of their past two annual bonuses. The amount of the Employee Payment is reduced if an employee has been with the Company for less than three years. An employee would receive one-third of the payment if he was employed by the Company for less than two years, and two-thirds of the payment if he was employed by the Company for between two and three years.
COMPENSATION COMMITTEE INTERLOCK AND INSIDER PARTICIPATION
      The Compensation Committee of the Board of Directors, during the last fiscal year ended December 31, 2004, consisted of Robert E. Aikman, Mr. Blackburn and Allen Finkelson. During the last fiscal year, there were no compensation committee interlocks or insider participation.
SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
      Section 16(a) of the Securities Exchange Act of 1934 requires executive officers, directors and persons who beneficially own more than ten percent of the Company’s stock to file initial reports of ownership and reports of changes of ownership with the Securities and Exchange Commission. Copies of such reports are required to be furnished to the Company.
      Based solely on a review of such forms furnished to the Company and certain written representations from the executive officers and directors, the Company believes that all Section 16(a) filing requirements applicable to its executive officers, directors and greater than 10% beneficial owners were complied with on a timely basis during 2004.
