Chesapeake

We are the second largest independent producer of natural gas in the United States, and we own interests in approximately 32,000 producing oil and natural gas wells that are currently producing approximately 1.6 bcfe per day, 92% of which is natural gas. Our strategy is focused on discovering, developing and acquiring onshore natural gas reserves in the U.S. east of the Rocky Mountains. Our most important operating area has historically been the Mid-Continent region, which includes Oklahoma, Arkansas, Kansas and the Texas Panhandle. At March 31, 2006, 49% of our proved oil and natural gas reserves were located in the Mid-Continent. During the past four years, we have also built significant positions in various conventional and unconventional plays in the South Texas and Texas Gulf Coast regions, the Permian Basin of West Texas and eastern New Mexico, the Barnett Shale area of North Texas, the Ark-La-Tex area of East Texas and northern Louisiana, the Appalachian Basin in West Virginia, eastern Kentucky, eastern Ohio and southern New York, the Caney and Woodford Shales in southeastern Oklahoma, the Fayetteville Shale in Arkansas and the Barnett and Woodford Shales in West Texas.

As of December 31, 2005, we had 7.5 tcfe of proved reserves, of which 92% were natural gas and all of which were onshore. During 2005, we produced an average of 1.3 bcfe per day, a 30% increase over the 1.0 bcfe per day produced in 2004. For 2005, we generated net income available to common shareholders of $880 million, or $2.51 per fully diluted common share, which was a 64% increase over the prior year.

During the first quarter of 2006, we led the nation in drilling activity with an average utilization of 77 operated rigs and 75 non-operated rigs. Through this drilling activity, we drilled 262 (210 net) operated wells and participated in another 371 (45 net) wells operated by other companies. Our success rate was 97% for operated wells and 98% for non-operated wells. We replaced our 137 bcfe of production with an internally estimated 427 bcfe of new proved reserves for a reserve replacement rate of 312%. Reserve replacement through the drillbit was 184 bcfe, or 135% of production (including 76 bcfe of upward performance revisions and 88 bcfe of downward revisions resulting from oil and natural gas price declines between December 31, 2005 and March 31, 2006), and reserve replacement through acquisitions was 243 bcfe, or 177% of production. As a result, our proved reserves grew by 4% during the first quarter of 2006, from 7.5 tcfe to 7.8 tcfe. Of the 7.8 tcfe, 64% were proved developed reserves.

In the first quarter of 2006, we produced an average of 1.5 bcfe per day, a 31% increase over the 1.2 bcfe per day produced in the first quarter of 2005. During the first quarter of 2006, we generated net income available to common shareholders of $604 million, or $1.44 per fully diluted common share, which was a 300% increase over the first quarter of 2005. Also, in the first quarter we added approximately 700 new employees to support our growth, which increased our total employee base to approximately 3,600 employees at March 31, 2006, and invested $200 million in leasehold (excluding leasehold acquired through acquisitions) and 3-D seismic data, all of which we consider the building blocks of future value creation.

From January 1, 1998 through March 31, 2006, we have been one of the most active consolidators of onshore U.S. natural gas assets, having purchased approximately 6.3 tcfe of proved reserves, at a total cost of approximately $12.2 billion (including $3.4 billion for unproved leasehold, but excluding $891 million of

1

deferred taxes established in connection with certain corporate acquisitions). Excluding the amounts allocated to unproved leasehold and deferred taxes, our acquisition cost per proved mcfe was $1.40 over this time period. During 2006, we have been especially active in the acquisitions market. Acquisition expenditures totaled $1.9 billion (including $1.1 billion for unproved leasehold), pro forma for our pending acquisitions. Through these acquisitions, we will have acquired an internally estimated 404 bcfe of proved oil and natural gas reserves.

On June 5, 2006, we announced that we had entered into an agreement to acquire from Four Sevens Oil Co. Ltd. and its equal equity partner, Sinclair Oil Corporation (collectively referred to as “Four Sevens/Sinclair”), 39,000 net acres of Barnett Shale leasehold, 30 mmcf of current natural gas current production and $55 million of midstream natural gas assets for $845 million in cash. We also announced that we acquired or agreed to acquire an additional 28,000 net acres of prospective Barnett Shale leasehold, primarily in Johnson and Tarrant Counties, Texas, from various additional sellers for $87 million. Please see “—Recent Developments—Pending Acquisitions.”

We intend to use the net proceeds from this offering, together with the net proceeds from our concurrent public offering of preferred stock and our concurrent public offering of common stock, to fund the purchase price for our pending acquisitions discussed above, to pay related fees and expenses, to repay outstanding indebtedness under our revolving bank credit facility and for general corporate purposes. Please see “Use of Proceeds.” There is no assurance, however, that these acquisitions will close, or close without material adjustment, as scheduled. Neither this offering nor our concurrently announced proposed public offerings of preferred stock and common stock are conditioned upon the closing of these acquisitions. Our pending acquisitions are not conditioned upon the closing of any of these offerings.

Our executive offices are located at 6100 North Western Avenue, Oklahoma City, Oklahoma 73118, and our telephone number is (405) 848-8000.

Business Strategy

Since our inception in 1989, Chesapeake’s goal has been to create value for investors by building one of the largest onshore natural gas resource bases in the United States. For much of the past eight years, our strategy to accomplish this goal has been to build a dominant operating position in the Mid-Continent region, the third largest natural gas supply region in the U.S. In building our industry-leading position in the Mid-Continent, we have integrated an aggressive and technologically advanced drilling program with an active property consolidation program focused on small to medium-sized corporate and property acquisitions. In 2002, we began expanding our focus from the Mid-Continent to other regions where we believed we could extend our successful strategy. To date, those areas have included the South Texas and Texas Gulf Coast regions, the Permian Basin of West Texas and eastern New Mexico, the Barnett Shale area of North Texas, the Ark-La-Tex area of East Texas and northern Louisiana, the Appalachian Basin in West Virginia, eastern Kentucky, eastern Ohio and southern New York, the Caney and Woodford Shales in southeastern Oklahoma, the Fayetteville Shale in Arkansas and the Barnett and Woodford Shales in West Texas. We believe significant elements of our successful Mid-Continent strategy of acquisition, exploitation, extension and exploration have been or will be successfully transferred to these areas.

Key elements of this business strategy are further explained below:

Make High-Quality Acquisitions. Our acquisition program is focused on acquisitions of natural gas properties that offer high-quality, long-lived production and significant development and high potential deep drilling opportunities. From January 1, 1998 through March 31, 2006 and pro forma for our pending acquisitions, we have purchased approximately 6.3 tcfe of proved reserves, at a total cost of approximately $12.2 billion (including $3.4

2

billion for unproved leasehold, but excluding $891 million of deferred taxes established in connection with certain corporate acquisitions). Excluding the amounts allocated to unproved leasehold and deferred taxes, our acquisition cost per proved mcfe was $1.40 over this time period. The vast majority of these acquisitions either increased our ownership in existing wells or fields or added additional drilling locations in our focused operating areas. Because these operating areas contain many smaller companies seeking liquidity opportunities and larger companies seeking to divest non-core assets, we expect to continue to find additional attractive acquisition opportunities in the future.

Grow through the Drillbit. One of Chesapeake’s most distinctive characteristics is our ability to increase reserves and production through the drillbit. We are currently utilizing 87 operated drilling rigs and 81 non-operated drilling rigs to conduct the most active drilling program in the United States. We focus both on finding significant new natural gas reserves and developing existing proved reserves, principally at deeper depths than the industry average. For the past seven years, we have been actively investing in leasehold, 3-D seismic information and human capital to be able to take advantage of the favorable drilling economics that exist today. While we believe U.S. natural gas production has declined during the past five years, we are one of the few large-cap companies that have been able to increase production, which we have successfully achieved for the past 16 consecutive years and 19 consecutive quarters. We believe key elements of the success and scale of our drilling programs have been our early recognition that natural gas prices were likely to move higher in the U.S. in the post-1999 period accompanied by our willingness to proactively hire new employees and to build the nation’s largest onshore leasehold and 3-D seismic inventories, all of which are the building blocks of a successful large-scale drilling program.

Build Regional Scale. We believe one of the keys to success in the natural gas exploration industry is to build significant operating scale in a limited number of operating areas that share many similar geological and operational characteristics. Achieving such scale provides many benefits, the most important of which are higher per unit revenues, lower per unit operating costs, greater rates of drilling success, higher returns from more easily integrated acquisitions and higher returns on drilling investments. We first began pursuing this focused strategy in the Mid-Continent in late 1997 and we are now the largest natural gas producer, the most active driller and the most active acquirer of leasehold and producing properties in the Mid-Continent. We believe this region, which trails only the Gulf Coast and Rocky Mountain basins in U.S. natural gas production, has many attractive characteristics. These characteristics include long-lived natural gas properties with predictable decline curves; multi-pay geological targets that decrease drilling risk and have resulted in a drilling success rate of 94% over the past 16 years; generally lower service costs than in more competitive or more remote basins; and a favorable regulatory environment with virtually no federal land ownership. We believe our other operating areas possess many of these same favorable characteristics and our goal is to become or remain a top five natural gas producer in each of our operating areas.

Focus on Low Costs. By minimizing lease operating costs and general and administrative expense through focused activities and increased scale, we have been able to deliver attractive financial returns through all phases of the commodity price cycle. We believe our low cost structure is the result of management’s effective cost-control programs, a high-quality asset base and extensive and competitive services, natural gas processing and transportation infrastructures that exist in our key operating areas. As of March 31, 2006, we operated approximately 18,800 wells, which accounted for approximately 80% of our daily production volume. This large percentage of operated properties provides us with a high degree of operating flexibility and cost control.

Improve our Balance Sheet. We have made significant progress in improving our balance sheet over the past seven years. From December 31, 1998 through March 31, 2006, we have increased our shareholders’ equity by $7.6 billion ($8.6 billion pro forma for our pending offerings of common stock and preferred stock) through a combination of earnings and common and preferred equity issuances. As of March 31, 2006, our debt as a percentage of total capitalization (total capitalization is the sum of debt and stockholders’ equity) was 46%, compared to 137% as of December 31, 1998. On a pro forma basis for our pending public offerings of common

3

stock and preferred stock, our recently completed preferred stock exchanges and this offering, our debt to total capitalization ratio as of March 31, 2006, would be 43%. We plan to continue improving our balance sheet in the years ahead.

Based on our view that natural gas will be in a tight supply/demand relationship in the U.S. during at least the next few years because of the significant structural challenges to growing natural gas supply and the growing demand for this clean-burning, domestically-produced fuel, we believe our focused natural gas acquisition, exploitation and exploration strategy should provide substantial value-creating growth opportunities in the years ahead. Our goal is to increase our overall production by 10% to 20% per year, with growth at an annual rate of 7% to 10% generated organically through the drillbit and the remaining growth generated through acquisitions. We have reached or exceeded this overall production goal in 11 of our 13 years as a public company.

Company Strengths

We believe the following six characteristics distinguish our past performance and differentiate our future growth potential from other independent natural gas producers:

High-Quality Asset Base. Our producing properties are characterized by long-lived reserves, established production profiles and an emphasis on onshore natural gas. Based upon current production and proved reserve estimates, and including estimates for our pending acquisitions, our proved reserves-to-production ratio, or reserve life, is approximately 14 years. In addition, we believe we are the sixth largest producer of natural gas in the U.S. (second among independents) and the fourth largest owner of proved U.S. natural gas reserves (first among independents). In each of our operating areas, our properties are concentrated in locations that enable us to establish substantial economies of scale in drilling and production operations and facilitate the application of more effective reservoir management practices. We intend to continue building our asset base in each of our operating areas through a balance of acquisitions, exploitation and exploration.

Low-Cost Producer. Our high-quality asset base, the work ethic of our employees, our hands-on management style and our headquarters location in Oklahoma City have enabled us to achieve a low operating and administrative cost structure. During the first quarter of 2006, our operating costs per unit of production were $1.48 per mcfe, which consisted of general and administrative expenses of $0.21 per mcfe (including non-cash stock-based compensation of $0.05 per mcfe), production expenses of $0.87 per mcfe and production taxes of $0.40 per mcfe. We believe this is one of the lowest cost structures among publicly traded, large-cap independent oil and natural gas producers.

Successful Acquisition Program. Our experienced acquisition team focuses on enhancing and expanding our existing assets in each of our operating areas. These areas are characterized by long-lived natural gas reserves, low lifting costs, multiple geological targets, favorable basis differentials to benchmark commodity prices, well-developed oil and natural gas transportation infrastructures and considerable potential for further consolidation of assets. Since 1998 and including our pending acquisitions, we have acquired approximately 6.3 tcfe of proved reserves that replaced 317% of our total production. We believe we are well-positioned to continue making attractive acquisitions as a result of our extensive track record of identifying, completing and integrating multiple successful acquisitions, our large operating scale and our knowledge and experience in the regions in which we operate.

Large Inventory of Drilling Projects. During the 16 years since our inception, we have been among the five most active drillers of new wells in the United States. Presently we are the most active driller in the U.S. with 87 operated and 81 non-operated rigs drilling. Through this high level of activity over the years, we have developed an industry-leading expertise in drilling deep vertical and horizontal wells in search of large natural gas

4

accumulations in challenging conventional and unconventional reservoirs. As a result of our successful acquisition program and active leasehold acquisition and seismic acquisition strategies, we have been able to accumulate a U.S. onshore leasehold position of approximately 9.3 million net acres, pro forma for our pending acquisitions, and have acquired rights to 12.3 million acres of onshore 3-D seismic data to provide informational advantages over our competitors and to help evaluate our large acreage inventory. On this very large acreage position, our technical teams believe approximately 31,000 exploratory and developmental drill sites exist, representing a backlog of more than ten years of future drilling opportunities at current drilling rates.

Hedging Program. We have used and intend to continue using hedging programs to reduce the risks inherent in acquiring and producing oil and natural gas reserves, commodities that are frequently characterized by significant price volatility. We believe this price volatility is likely to continue in the years ahead and that we can use this volatility to our benefit by taking advantage of prices when they reach levels that management believes are either unsustainable for the long-term or provide unusually high rates of return on our invested capital. We currently have natural gas hedges in place covering 88%, 69% and 55% of our anticipated natural gas production for the remainder of 2006 (including the second quarter of 2006) and all of 2007 and 2008 at average NYMEX prices of $9.08, $9.86 and $9.34 per mcf, respectively. In addition, we have 79%, 56% and 48% of our anticipated oil production hedged for the remainder of 2006 (including the second quarter of 2006) and all of 2007 and 2008 at average NYMEX prices of $63.24, $68.79 and $69.50 per barrel of oil, respectively. During the first quarter of 2006, we realized gains from our hedging program of approximately $248.2 million.

Entrepreneurial Management. Our management team formed the company in 1989 with an initial capitalization of $50,000 and fewer than ten employees. Since then, our management team has guided the company through various operational and industry challenges and extremes of oil and natural gas prices to create the second largest independent producer of natural gas in the U.S. with approximately 4,000 employees and an enterprise value of approximately $20.2 billion (based on a common stock price of $28.50 per share and pro forma for this offering and our pending offerings of preferred stock and common stock). Our chief executive officer and co-founder, Aubrey K. McClendon, has been in the oil and natural gas industry for 25 years and beneficially owns, as of June 23, 2006, approximately 25 million shares of our common stock.

Recent Developments

Pending Acquisitions. On June 5, 2006, we announced that we had entered into an agreement to acquire from Four Sevens/Sinclair, 39,000 net acres of Barnett Shale leasehold, 30 mmcf of current natural gas production and $55 million of mid-stream natural gas assets for $845 million in cash. Of the 39,000 net acres, 26,000 net acres are located in Johnson and Tarrant Counties, Texas, where we have identified 500 net potential drillsites, and 13,000 net acres are located in counties outside our core focus area where we have not yet identified any drilling opportunities that would produce returns as competitive as those in our core focus area. We also announced that we acquired or agreed to acquire an additional 28,000 net acres of prospective Barnett Shale leasehold, primarily in Johnson and Tarrant Counties, from various additional sellers for $87 million. On these 28,000 acres, we anticipate drilling as many as 400 net wells to develop these properties under current market conditions.

We have also recently agreed to invest approximately $450 million to acquire an additional 225,000 net acres of leasehold in the Delaware Basin shale plays of West Texas and to acquire a leading drilling contractor in the Appalachian Basin. We may use part of the proceeds from this offering and our concurrent public offerings together with borrowings under our revolving bank credit facility to finance such acquisitions, which we expect to close in July 2006.

There is no assurance that our pending acquisitions will close, close without material adjustment, or close as scheduled. Neither this offering nor either of our concurrently announced proposed offerings is conditioned upon

5

the closing of these acquisitions. The pending acquisitions are not conditioned upon the closing of any of these offerings. We intend to finance these acquisitions with the net proceeds from this offering and our concurrent public offerings of preferred stock and common stock. If one or more of the concurrent offerings are not consummated, we intend to finance these acquisitions with the net proceeds from this offering and borrowings under our revolving bank credit facility.

Pending Public Offerings. We are concurrently conducting separate public offerings of 2,000,000 shares of mandatory convertible preferred stock with a stated value of $500 million (plus up to an additional 300,000 shares to cover the option of the underwriters to purchase additional shares) and 20,000,000 shares of our common stock (plus up to an additional 3,000,000 shares to cover the option of the underwriters to purchase additional shares). This prospectus shall not be deemed an offer to sell or a solicitation of an offer to buy any of our preferred stock or common stock. There is no assurance that our concurrent public offerings will be completed or, if completed, that they will be completed for the amounts contemplated. The completion of this offering is not conditioned on the completion of our pending acquisitions or the completion of our concurrent public offerings of preferred stock or common stock.

The Offering

The summary below describes the principal terms of the notes. Some of the terms and conditions described below are subject to important limitations and exceptions. The “Description of Notes” section of this prospectus contains a more detailed description of the terms and conditions of the notes.

Issuer Chesapeake Energy Corporation.

Notes Offered $500,000,000 in aggregate principal amount of         % Senior Notes due 2013.

Maturity Date                          , 2013.

Interest Interest on the notes will accrue at an annual rate of         %. Interest will be paid semi-annually in arrears on                   and                           of each year, commencing              , 2006.

Guarantees The notes will be unconditionally guaranteed, jointly and severally, by (i) each of our existing domestic subsidiaries, other than Nomac 100 Corp. and certain de minimus subsidiaries, and one of our foreign subsidiaries and (ii) each of our future domestic subsidiaries that guarantees any other indebtedness of us or a subsidiary guarantor in excess of $5 million. The guarantee will be released if we dispose of the subsidiary guarantor or it ceases to guarantee certain other indebtedness of us or any other subsidiary guarantor.

Ranking The notes will be unsecured and will rank equally in right of payment to all of our existing and future senior indebtedness. The notes will rank senior in right of payment to all of our future subordinated indebtedness. Holders of our secured indebtedness have claims with respect to our assets constituting collateral for their indebtedness that are prior to your claim under the notes. In addition, the notes will be structurally subordinated to any indebtedness of a subsidiary that is not a subsidiary guarantor. Please read “Description of Notes—Ranking.”

As of March 31, 2006, we had approximately $6.5 billion in principal amount of senior indebtedness outstanding, of which $444 million was secured indebtedness under our revolving bank credit facility. After giving effect to this offering, our pending offerings of common stock and preferred stock and the ultimate application of net proceeds therefrom as described under “Use of Proceeds,” on a pro forma basis as of March 31, 2006, we would have had approximately $6.5 billion in principal amount of senior indebtedness outstanding, none of which would have been secured indebtedness. As of June 23, 2006, we had outstanding borrowings of $1.188 billion under our revolving bank credit facility. Nomac 100 Corp., which holds approximately $150 million in assets, is a guarantor of all of our other existing senior indebtedness, which will effectively rank senior to the notes with respect to the assets of Nomac 100 Corp.

Make-Whole Redemption We may redeem some or all of the notes at any time prior to maturity by the payment of a make-whole premium described in the

7

“Description of Notes—Make-Whole Redemption” section of this prospectus.

Restrictive Covenants The indenture governing the notes will contain covenants that limit our ability and our subsidiaries’ ability to:

• incur certain secured indebtedness;

• enter into sale-leaseback transactions; and

• consolidate, merge or transfer assets.

The covenants are subject to a number of exceptions and qualifications. See “Description of Notes—Certain Covenants.”

Use of Proceeds We expect the net proceeds to us from this offering, after deducting discounts to the underwriters and estimated expenses of the offering payable by us, to be approximately $491.6 million. We intend to use the net proceeds from this offering, together with the net proceeds from our pending public offerings of preferred stock and common stock to finance the purchase of our pending acquisitions, to pay related fees and expenses, to repay outstanding indebtedness under our revolving bank credit facility and for general corporate purposes, including to finance possible future acquisitions. Please see “Use of Proceeds.”

Book-Entry, Delivery and Form Initially, the notes will be represented by one or more permanent global certificates in definitive, fully registered form deposited with a custodian for, and registered in the name of, a nominee of The Depository Trust Company.

Risk Factors

An investment in the notes involves certain risks that a potential investor should carefully evaluate prior to making an investment in the notes. Please read “Risk Factors” beginning on page 13.

Summary Reserve Information

The following table sets forth our estimated proved reserves and the present value of the proved reserves as of December 31, 2005 (based on our weighted average wellhead prices at December 31, 2005 of $56.41 per barrel of oil and $8.76 per mcf of natural gas). These prices were based on the cash spot prices for oil and natural gas at December 31, 2005.

Total	103,323	6,900,754	7,520,690	100	%	$	22,933,594	(1)

(1) The standardized measure of discounted future net cash flows at December 31, 2005 was $16.0 billion.

As of December 31, 2005, the present value of our proved developed reserves as a percentage of total proved reserves was 71%, and the volume of our proved developed reserves as a percentage of total proved reserves was 65%. Natural gas reserves accounted for 92% of the volume of total proved reserves at December 31, 2005.

Future prices and costs may be materially higher or lower than the prices and costs as of the date of any estimate. A change in price of $0.10 per mcf for natural gas and $1.00 per barrel for oil would result in a change in our December 31, 2005 present value of estimated future net revenue of proved reserves of approximately $315 million and $50 million, respectively.

RISK FACTORS

In addition to the other information set forth elsewhere or incorporated by reference in this prospectus, the following factors relating to our company and the offering should be considered carefully before making an investment in the notes offered hereby.

Risks Relating to Our Business

Oil and gas prices are volatile. A decline in prices could adversely affect our financial position, financial results, cash flows, access to capital and ability to grow.

Our revenues, operating results, profitability and future rate of growth depend primarily upon the prices we receive for the oil and gas we sell. Prices also affect the amount of cash flow available for capital expenditures and our ability to borrow money or raise additional capital. The amount we can borrow from banks is subject to periodic redeterminations based on prices specified by our bank group at the time of redetermination. In addition, we may have ceiling test write-downs in the future if prices fall significantly.

Historically, the markets for oil and gas have been volatile and they are likely to continue to be volatile. Wide fluctuations in oil and gas prices may result from relatively minor changes in the supply of and demand for oil and natural gas, market uncertainty and other factors that are beyond our control, including:

• worldwide and domestic supplies of oil and gas;

• weather conditions;

• the level of consumer demand;

• the price and availability of alternative fuels;

• the proximity and capacity of natural gas pipelines and other transportation facilities;

• the price and level of foreign imports;

• domestic and foreign governmental regulations and taxes;

• the ability of the members of the Organization of Petroleum Exporting Countries to agree to and maintain oil price and production controls;

• political instability or armed conflict in oil-producing regions; and

• overall domestic and global economic conditions.

These factors and the volatility of the energy markets make it extremely difficult to predict future oil and gas price movements with any certainty. Declines in oil and natural gas prices would not only reduce revenue, but could reduce the amount of oil and gas that we can produce economically and, as a result, could have a material adverse effect on our financial condition, results of operations and reserves. Further, oil and gas prices do not necessarily move in tandem. Because approximately 92% of our reserves at December 31, 2005 are natural gas reserves, we are more affected by movements in natural gas prices.

Our level of indebtedness and preferred stock may adversely affect operations and limit our growth, and we may have difficulty making debt service payments on our indebtedness as such payments become due.

As of March 31, 2006, we had long-term indebtedness of approximately $6.3 billion, with $444 million of outstanding borrowings drawn under our revolving bank credit facility. Our long-term indebtedness represented 46% of our total book capitalization at March 31, 2006. We expect to continue to be highly leveraged in the foreseeable future.

13

Our level of indebtedness and preferred stock affects our operations in several ways, including the following:

• a portion of our cash flows from operating activities must be used to service our indebtedness and pay dividends on our preferred stock and is not available for other purposes;

• we may be at a competitive disadvantage as compared to similar companies that have less debt;

• the covenants contained in the agreements governing our outstanding indebtedness and future indebtedness may limit our ability to borrow additional funds, pay dividends and make certain investments and may also affect our flexibility in planning for, and reacting to, changes in the economy and in our industry;

• additional financing in the future for working capital, capital expenditures, acquisitions, general corporate or other purposes may have higher costs and more restrictive covenants;

• changes in the credit ratings of our debt may negatively affect the cost, terms, conditions and availability of future financing, and lower ratings will increase the interest rate and fees we pay on our revolving bank credit facility; and

• we may be more vulnerable to general adverse economic and industry conditions.

We may incur additional debt, including significant secured indebtedness, or issue additional series of preferred stock in order to make future acquisitions or to develop our properties. A higher level of indebtedness and/or additional preferred stock increases the risk that we may default on our obligations. Our ability to meet our debt obligations and to reduce our level of indebtedness depends on our future performance. General economic conditions, oil and gas prices and financial, business and other factors affect our operations and our future performance. Many of these factors are beyond our control. We may not be able to generate sufficient cash flow to pay the interest on our debt, and future working capital, borrowings or equity financing may not be available to pay or refinance such debt. Factors that will affect our ability to raise cash through an offering of our capital stock or a refinancing of our debt include financial market conditions, the value of our assets and our performance at the time we need capital.

In addition, our bank borrowing base is subject to periodic redetermination. A lowering of our borrowing base could require us to repay indebtedness in excess of the borrowing base, or we might need to further secure the lenders with additional collateral.

Competition in the oil and natural gas industry is intense, and many of our competitors have greater financial and other resources than we do.

We operate in the highly competitive areas of oil and natural gas acquisition, development, exploitation, exploration and production. We face intense competition from both major and other independent oil and natural gas companies in each of the following areas:

• seeking to acquire desirable producing properties or new leases for future exploration; and

• seeking to acquire the equipment and expertise necessary to develop and operate our properties.

Many of our competitors have financial and other resources substantially greater than ours, and some of them are fully integrated oil companies. These companies may be able to pay more for development prospects and productive oil and natural gas properties and may be able to define, evaluate, bid for and purchase a greater number of properties and prospects than our financial or human resources permit. Our ability to develop and exploit our oil and natural gas properties and to acquire additional properties in the future will depend upon our ability to successfully conduct operations, evaluate and select suitable properties and consummate transactions in this highly competitive environment.

Significant capital expenditures are required to replace our reserves.

Our exploration, development and acquisition activities require substantial capital expenditures. Historically, we have funded our capital expenditures through a combination of cash flows from operations, our revolving bank credit facility and debt and equity issuances. Future cash flows are subject to a number of variables, such as the level of production from existing wells, prices of oil and gas, and our success in developing and producing new reserves. If revenue were to decrease as a result of lower oil and gas prices or decreased production, and our access to capital were limited, we would have a reduced ability to replace our reserves. If our cash flow from operations is not sufficient to fund our capital expenditure budget, we may not be able to access additional bank debt, debt or equity or other methods of financing on an economic basis to meet these requirements.

If we are not able to replace reserves, we may not be able to sustain production.

Our future success depends largely upon our ability to find, develop or acquire additional oil and gas reserves that are economically recoverable. Unless we replace the reserves we produce through successful development, exploration or acquisition activities, our proved reserves and production will decline over time. In addition, approximately 35% of our total estimated proved reserves (by volume) at December 31, 2005 were undeveloped. By their nature, estimates of undeveloped reserves are less certain. Recovery of such reserves will require significant capital expenditures and successful drilling operations. Our reserve estimates reflect that our production rate on producing properties will decline approximately 24% from 2006 to 2007. Thus, our future oil and natural gas reserves and production and, therefore, our cash flow and income are highly dependent on our success in efficiently developing and exploiting our current reserves and economically finding or acquiring additional recoverable reserves.

The actual quantities and present value of our proved reserves may prove to be lower than we have estimated.

This prospectus and the documents incorporated by reference herein contain estimates of our proved reserves and the estimated future net revenues from our proved reserves. These estimates are based upon various assumptions, including assumptions required by the SEC relating to oil and gas prices, drilling and operating expenses, capital expenditures, taxes and availability of funds. The process of estimating oil and gas reserves is complex. The process involves significant decisions and assumptions in the evaluation of available geological, geophysical, engineering and economic data for each reservoir. Therefore, these estimates are inherently imprecise.

Actual future production, oil and gas prices, revenues, taxes, development expenditures, operating expenses and quantities of recoverable oil and gas reserves most likely will vary from these estimates. Such variations may be significant and could materially affect the estimated quantities and present value of our proved reserves. In addition, we may adjust estimates of proved reserves to reflect production history, results of exploration and development drilling, prevailing oil and gas prices and other factors, many of which are beyond our control. Our properties may also be susceptible to hydrocarbon drainage from production by operators on adjacent properties.

At December 31, 2005, approximately 35% of our estimated proved reserves (by volume) were undeveloped. Recovery of undeveloped reserves requires significant capital expenditures and successful drilling operations. These reserve estimates include the assumption that we will make significant capital expenditures to develop the reserves, including approximately $1.8 billion in 2006. You should be aware that the estimated costs may not be accurate, development may not occur as scheduled and results may not be as estimated.

You should not assume that the present values referred to in this prospectus and the documents incorporated by reference herein represent the current market value of our estimated oil and gas reserves. In accordance with SEC requirements, the estimates of our present values are based on prices and costs as of the date of the estimates. The December 31, 2005 present value is based on weighted average oil and natural gas wellhead prices of

15

$56.41 per barrel of oil and $8.76 per mcf of natural gas. Actual future prices and costs may be materially higher or lower than the prices and costs as of the date of an estimate.

Any changes in consumption by oil and natural gas purchasers or in governmental regulations or taxation will also affect actual future net cash flows.

The timing of both the production and the expenses from the development and production of oil and gas properties will affect both the timing of actual future net cash flows from our proved reserves and their present value. In addition, the 10% discount factor, which is required by the SEC to be used in calculating discounted future net cash flows for reporting purposes, is not necessarily the most accurate discount factor. The effective interest rate at various times and the risks associated with our business or the oil and natural gas industry in general will affect the accuracy of the 10% discount factor.

Acquisitions may prove to be worth less than we paid because of uncertainties in evaluating recoverable reserves and potential liabilities.

Our recent growth is due in large part to acquisitions of exploration and production companies, producing properties and undeveloped leasehold. We expect acquisitions will also contribute to our future growth. Successful acquisitions require an assessment of a number of factors, including estimates of recoverable reserves, exploration potential, future oil and gas prices, operating costs and potential environmental and other liabilities. Such assessments are inexact and their accuracy is inherently uncertain. In connection with our assessments, we perform a review of the acquired properties which we believe is generally consistent with industry practices. However, such a review will not reveal all existing or potential problems. In addition, our review may not permit us to become sufficiently familiar with the properties to fully assess their deficiencies and capabilities. We do not inspect every well. Even when we inspect a well, we do not always discover structural, subsurface and environmental problems that may exist or arise. We are generally not entitled to contractual indemnification for preclosing liabilities, including environmental liabilities. Normally, we acquire interests in properties on an “as is” basis with limited remedies for breaches of representations and warranties. As a result of these factors, we may not be able to acquire oil and gas properties that contain economically recoverable reserves or be able to complete such acquisitions on acceptable terms.

As new owners, we may not effectively consolidate and integrate acquired operations, particularly when we make significant acquisitions outside our historical operating areas.

Significant acquisitions present operational and administrative challenges that may prove more difficult than anticipated. The failure to consolidate functions and integrate procedures, personnel and operations in an effective and timely manner may adversely affect our business and results of operations, at least temporarily. Significant acquisitions can change the nature of our operations and business depending upon the character of the acquired properties, which may have substantially different operating and geological characteristics or be in different geographic locations than our existing properties. To the extent that we acquire properties substantially different from the properties in our primary operating areas or acquire properties that require different technical expertise, we may not be able to realize the economic benefits of these acquisitions as efficiently as in our prior acquisitions.

Exploration and development drilling may not result in commercially productive reserves.

We do not always encounter commercially productive reservoirs through our drilling operations. The new wells we drill or participate in may not be productive and we may not recover all or any portion of our investment in wells we drill or participate in. The seismic data and other technologies we use do not allow us to know conclusively prior to drilling a well that oil or gas is present or may be produced economically. The cost of drilling, completing and operating a well is often uncertain, and cost factors can adversely affect the economics of a project. Our efforts will be unprofitable if we drill dry wells or wells that are productive but do not produce

16

enough reserves to return a profit after drilling, operating and other costs. Further, our drilling operations may be curtailed, delayed or canceled as a result of a variety of factors, including:

• increases in the cost of, or shortages or delays in the availability of, drilling rigs and equipment;

• unexpected drilling conditions;

• title problems;

• pressure or irregularities in formations;

• equipment failures or accidents;

• adverse weather conditions; and

• compliance with environmental and other governmental requirements.

Future price declines may result in a write-down of our asset carrying values.

We utilize the full cost method of accounting for costs related to our oil and gas properties. Under this method, all such costs (for both productive and nonproductive properties) are capitalized and amortized on an aggregate basis over the estimated lives of the properties using the unit-of-production method. However, these capitalized costs are subject to a ceiling test which limits such pooled costs to the aggregate of the present value of future net revenues attributable to proved oil and natural gas reserves discounted at 10% plus the lower of cost or market value of unproved properties. The full cost ceiling is evaluated at the end of each quarter using the prices for oil and gas at that date, adjusted for the impact of derivatives accounted for as cash flow hedges. A significant decline in oil and gas prices from current levels, or other factors, without other mitigating circumstances, could cause a future writedown of capitalized costs and a non-cash charge against future earnings.

Our hedging activities may reduce the realized prices received for our oil and natural gas sales and require us to provide collateral for hedging liabilities.

In order to manage our exposure to price volatility in marketing our oil and gas, we enter into oil and gas price risk management arrangements for a portion of our expected production. Commodity price hedging may limit the prices we actually realize and therefore reduce oil and natural gas revenues in the future. The fair value of our oil and gas derivative instruments outstanding as of March 31, 2006 was an asset of approximately $43.5 million. In addition, our commodity price risk management transactions may expose us to the risk of financial loss in certain circumstances, including instances in which:

• our production is less than expected;

• there is a widening of price differentials between delivery points for our production and the delivery point assumed in the hedge arrangement; or

• the counterparties to our contracts fail to perform under the contracts.

All but two of our commodity price risk management counterparties require us to provide assurances of performance in the event that the counterparties’ mark-to-market exposure to us exceeds certain levels. Most of these arrangements allow us to minimize the potential liquidity impact of significant mark-to-market fluctuations by making collateral allocations from our revolving bank credit facility or directly pledging oil and natural gas properties rather than posting cash or letters of credit with the counterparties. As of March 31, 2006, we were required to post a total of $50 million of collateral with our counterparties through letters of credit issued under our revolving bank credit facility, in addition to collateral allocations and pledges of oil and natural gas properties, with respect to commodity price risk management transactions. As of June 23, 2006, we had outstanding transactions with twelve counterparties, seven of which hold collateral allocations from our bank facility or liens against certain oil and natural gas properties under our secured hedging facilities, and two of which do not require us to provide security for our risk management transactions. We were not required to post

17

cash or letters of credit with the remaining three counterparties as of June 23, 2006. Future collateral requirements are uncertain and will depend on the arrangements with our counterparties and highly volatile natural gas and oil prices.

Lower oil and gas prices could negatively impact our ability to borrow.

Our revolving bank credit facility limits our borrowings to the lesser of the borrowing base (currently $2.5 billion) and the total commitments (currently $2.0 billion). The borrowing base is determined periodically at the discretion of the banks and is based in part on oil and natural gas prices. Additionally, some of our indentures contain covenants limiting our ability to incur indebtedness in addition to that incurred under our revolving bank credit facility. These indentures limit our ability to incur additional indebtedness unless we meet one of two alternative tests. The first alternative is based on our adjusted consolidated net tangible assets (as defined in all of our indentures), which is determined using discounted future net revenues from proved oil and natural gas reserves as of the end of each year. The second alternative is based on the ratio of our adjusted consolidated EBITDA (as defined in the relevant indentures) to our adjusted consolidated interest expense over a trailing twelve-month period. As of the date of this prospectus, we are permitted to incur significant additional indebtedness under both of these debt incurrence tests. Lower oil and gas prices in the future could reduce our adjusted consolidated EBITDA, as well as our adjusted consolidated net tangible assets, and thus could reduce our ability to incur additional indebtedness.

Oil and natural gas drilling and producing operations can be hazardous and may expose us to environmental liabilities.

Oil and natural gas operations are subject to many risks, including well blowouts, cratering and explosions, pipe failure, fires, formations with abnormal pressures, uncontrollable flows of oil, natural gas, brine or well fluids, and other environmental hazards and risks. Our drilling operations involve risks from high pressures and from mechanical difficulties such as stuck pipes, collapsed casings and separated cables. If any of these risks occurs, we could sustain substantial losses as a result of:

• injury or loss of life;

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

• pollution or other environmental damage;

• clean-up responsibilities;

• regulatory investigations and administrative, civil and criminal penalties; and

• injunctions resulting in limitation or suspension of operations.

There is inherent risk of incurring significant environmental costs and liabilities in our exploration and production operations due to our generation, handling, and disposal of materials including wastes and petroleum hydrocarbons. We may incur joint and several, strict liability under applicable federal and state environmental laws in connection with releases of petroleum hydrocarbons and wastes on, under or from our leased or owned properties, some of which have been used for oil and natural gas exploration and production activities for a number of years, oftentimes by third parties not under our control. While we may maintain insurance against some, but not all, of the risks described above, our insurance may not be adequate to cover casualty losses or liabilities. Also, in the future we may not be able to obtain insurance at premium levels that justify its purchase.

Risks Related to the Notes

Holders of the notes will be effectively subordinated to all of our and our subsidiaries’ secured indebtedness.

Holders of our secured indebtedness, which is comprised primarily of the indebtedness under our revolving bank credit facility, have claims with respect to our assets constituting collateral for their indebtedness that are

18

prior to your claims under the notes. In the event of a default on the notes or our bankruptcy, liquidation or reorganization, those assets would be available to satisfy obligations with respect to the indebtedness secured thereby before any payment could be made on the notes. Accordingly, the secured indebtedness would effectively be senior to the notes to the extent of the value of the collateral securing the indebtedness. While the indenture governing the notes places some limitations on our ability to create liens, there are significant exceptions to these limitations, including with respect to sale and leaseback transactions, that will allow us to secure indebtedness without equally and ratably securing the notes. To the extent the value of the collateral is not sufficient to satisfy the secured indebtedness, the holders of that indebtedness would be entitled to share with the holders of the notes and the holders of other claims against us with respect to our other assets. In addition, in certain circumstances a subsidiary may not be required to be, or may be delayed in becoming, a Subsidiary Guarantor. The notes will be structurally subordinated to any indebtedness of a subsidiary that is not a Subsidiary Guarantor.

A guarantee could be voided if the guarantor fraudulently transferred the guarantee at the time it incurred the indebtedness, which could result in the noteholders being able to rely on only us to satisfy claims.

Under U.S. bankruptcy law and comparable provisions of state fraudulent transfer laws, a guarantee can be voided, or claims under a guarantee may be subordinated to all other debts of that guarantor if, among other things, the guarantor, at the time it incurred the indebtedness evidenced by its guarantee:

• intended to hinder, delay or defraud any present or future creditor or received less than reasonably equivalent value or fair consideration for the incurrence of the guarantee;

• was insolvent or rendered insolvent by reason of such incurrence;

• was engaged in a business or transaction for which the guarantor’s remaining assets constituted unreasonably small capital; or

• intended to incur, or believed that it would incur, debts beyond its ability to pay those debts as they mature.

In addition, any payment by that guarantor under a guarantee could be voided and required to be returned to the guarantor or to a fund for the benefit of the creditors of the guarantor.

The measures of insolvency for purposes of fraudulent transfer laws vary depending upon the governing law. Generally, a guarantor would be considered insolvent if:

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

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

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

On the basis of historical financial information, recent operating history and other factors, we believe that the subsidiary guarantees are being incurred for proper purposes and in good faith and that each subsidiary guarantor, after giving effect to its guarantee of the notes, will not be insolvent, have unreasonably small capital for the business in which it is engaged or have incurred debts beyond its ability to pay those debts as they mature. We cannot be certain, however, that a court would agree with our conclusions in this regard.

You may find it difficult to sell your notes.

The notes will constitute a new issue of securities with no established public market. Although the underwriters have indicated that they intend to make a market in the notes, they are not obligated to do so and

19

any of their market making activities may be terminated or limited at any time. In addition, although we have registered the offer and sale of the notes under the Securities Act of 1933 and intend to apply for a listing of the notes on the New York Stock Exchange, there can be no assurance as to the liquidity of markets that may develop for the notes, the ability of noteholders to sell their notes or the prices at which notes could be sold. The notes may trade at prices that are lower than their initial purchase price depending on many factors, including prevailing interest rates and the markets for similar securities. The liquidity of trading markets for the notes may also be adversely affected by general declines or disruptions in the markets for debt securities. Those market declines or disruptions could adversely affect the liquidity of and market for the notes independent of our financial performance or prospects. An active market for the notes may not develop or, if developed, may not continue. In the absence of an active trading market, you may not be able to transfer the notes within the time or at the price you desire.

The notes are not subject to a change-of-control put option and lack some covenants typically found in other comparably rated public debt securities.

Although the notes are rated below investment grade by both Standard & Poor’s and Moody’s Investors Service, they lack the protection for holders of a change-of-control put option and several financial and other restrictive covenants associated with several other series of our outstanding senior notes and typically associated with comparably rated public debt securities, including:

• incurrence of additional indebtedness;

• payment of dividends and other restricted payments;

• sale of assets and the use of proceeds therefrom;

• transactions with affiliates; and

• dividend and other payment restrictions affecting subsidiaries.

USE OF PROCEEDS

We expect the net proceeds from this offering to be approximately $491.6 million, after deducting underwriters’ discounts and the estimated expenses of the offering payable by us. We intend to use the net proceeds from this offering, together with approximately $484.8 million in expected net proceeds from our pending public offering of preferred stock and $548.4 million in expected net proceeds from our pending public offering of common stock (each assuming no exercise of the underwriters’ option to purchase additional shares), to fund the purchase of our pending acquisitions and to pay related fees and expenses. Any remaining net proceeds will be used to repay borrowings under our revolving bank credit facility and for general corporate purposes, including funding our pending acreage acquisition in the Delaware Basin of West Texas, our pending drilling company acquisition and other possible future acquisitions. This offering, however, is not conditioned upon the closing of the pending acquisitions or the consummation of either of our pending public offerings of preferred stock and common stock. Should the pending public offerings be unsuccessful, we will finance our pending acquisitions with borrowings under our revolving bank credit facility. Affiliates of certain of the underwriters in this offering are lenders under our existing revolving bank credit facility and may receive a portion of the proceeds from this offering. See “Underwriting.”

DESCRIPTION OF NOTES

Chesapeake Energy Corporation will issue the notes offered hereby (the “Notes”) under an indenture to be dated as of                     , 2006 (the “Indenture”), among the Company, as issuer, the Subsidiary Guarantors, as guarantors, and The Bank of New York Trust Company, N.A., as trustee (the “Trustee”). The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (the “Trust Indenture Act”).

The following description is only a summary of the material provisions of the Notes and the Indenture. These descriptions do not purport to be complete and are subject to, and are qualified in their entirety by reference to, the Notes and the Indenture. You may request copies of the Indenture at our address set forth under the heading “Where You Can Find More Information.”

Certain terms used in this description are defined under the subheading “—Certain Definitions.” In this description, the words “Company” and “we” refer only to Chesapeake Energy Corporation and not to any of its subsidiaries.

General

The Company will issue the Notes initially with a maximum aggregate principal amount of $500 million. The Company is permitted to issue additional Notes under the Indenture in an unlimited aggregate principal amount (“Add-On Notes”). Any Add-On Notes that are actually issued will be treated as issued and outstanding Notes (as the same class as the initial Notes) for all purposes of the Indenture and this “Description of Notes,” unless the context indicates otherwise. Each Note will mature on                      , 2013 and will bear interest at the rate of interest per annum indicated on the cover page of this prospectus.

Interest on the Notes issued in this offering will accrue from the Issue Date at an annual rate of             %, payable semi-annually in arrears on                       and                       of each year, commencing                      , 2006. We will make each interest payment to the holders of record of the Notes at the close of business on the                       or                       preceding such interest payment date. Interest will be computed on the basis of a 360-day year of twelve 30-day months. Principal, premium, if any, and interest will be payable at the offices of the Trustee and the paying agent, provided that, at the option of the Company, payment of interest on Notes not in global form may be made by check mailed to the address of the Person entitled thereto as it appears in the register of the Notes maintained by the registrar. Initially, the Trustee will also act as paying agent and registrar for the Notes.

The Notes are unsecured senior obligations of the Company. The Notes rank pari passu in right of payment with all existing and future Senior Indebtedness of the Company and rank senior in right of payment to all future Subordinated Indebtedness of the Company.

Guarantees

On the Issue Date, all the existing domestic subsidiaries, other than certain de minimus subsidiaries and Nomac 100 Corp., which holds approximately $150 million in assets, and one foreign subsidiary of the Company will fully and unconditionally guarantee, on a joint and several basis, the Company’s obligations to pay principal of, premium, if any, and interest on the Notes. The Indenture provides that each Person that becomes a domestic Subsidiary after the Issue Date and guarantees any other Indebtedness of the Company or a Subsidiary Guarantor in excess of a De Minimis Guaranteed Amount will guarantee the payment of the Notes within 180 days after the later of (i) the date it becomes a domestic Subsidiary and (ii) the date it guarantees such other Indebtedness, provided that no guarantee shall be required if the Subsidiary merges into the Company or an existing Subsidiary Guarantor and the surviving entity remains a Subsidiary Guarantor. Nomac 100 Corp. is a guarantor of all of our

24

existing senior indebtedness. Accordingly, such other indebtedness will effectively rank senior to the Notes with respect to the assets of Nomac 100 Corp.

The obligations of each Subsidiary Guarantor under its Guarantee will be limited as necessary to prevent that Guarantee from constituting a fraudulent conveyance or fraudulent transfer under federal, state or foreign law. Each Subsidiary Guarantor that makes a payment or distribution under a Guarantee shall be entitled to a contribution from each other Subsidiary Guarantor in a pro rata amount based on the respective net assets of each Subsidiary Guarantor at the time of such payment determined in accordance with GAAP.

If a Guarantee were rendered voidable, it could be subordinated by a court to all other indebtedness (including guarantees and other contingent liabilities) of the applicable Subsidiary Guarantor, and, depending on the amount of such indebtedness, a Subsidiary Guarantor’s liability on its Guarantee could be reduced to zero. Please read “Risk Factors—Risks Related to the Notes—A guarantee could be voided if the guarantor fraudulently transferred the guarantee at the time it incurred the indebtedness, which could result in the noteholders being able to rely on only us to satisfy claims.”

Subject to the next succeeding paragraph, no Subsidiary Guarantor may consolidate or merge with or into (whether or not such Subsidiary Guarantor is the surviving Person) another Person unless:

(1) the Person formed by or surviving any such consolidation or merger (if other than such Subsidiary Guarantor) assumes all the obligations of such Subsidiary Guarantor under the Indenture and the Notes pursuant to a supplemental indenture, in a form reasonably satisfactory to the Trustee, and

(2) immediately after such transaction, no Default or Event of Default exists.

The preceding does not prohibit a merger between Subsidiary Guarantors or a merger between the Company and a Subsidiary Guarantor.

In the event of a sale or other disposition of all or substantially all of the assets of any Subsidiary Guarantor, or a sale or other disposition of all the Capital Stock of such Subsidiary Guarantor, in any case whether by way of merger, consolidation or otherwise, 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 assets (in the event of a sale or other disposition of all or substantially all of the assets of such Subsidiary Guarantor) will be released and relieved of any obligations under its Guarantee. Further, a Subsidiary Guarantor will be released and relieved from any obligations under its Guarantee if it ceases to guarantee any other Indebtedness of the Company or any other Subsidiary Guarantor other than a De Minimis Guaranteed Amount.

Ranking

Senior Indebtedness versus Notes. The Indebtedness evidenced by the Notes and the Guarantees will be unsecured and will rank pari passu in right of payment to all Senior Indebtedness of the Company and the Subsidiary Guarantors, as the case may be.

As of March 31, 2006, the Company and the Subsidiary Guarantors had approximately $6.5 billion in principal amount of Senior Indebtedness outstanding, of which $444 million was secured indebtedness under our revolving bank credit facility. Upon completion of this offering, our pending offerings of preferred stock and common stock and the ultimate application of the net proceeds therefrom as described under “Use of Proceeds,” we would have had, on a pro forma basis as adjusted as of March 31, 2006, approximately $6.5 billion in principal amount of Senior Indebtedness outstanding, none of which would have been secured. If our pending acquisitions were paid for entirely with debt, we would expect to have long-term indebtedness of approximately $7.3 billion immediately following the acquisition. As of June 23, 2006, we had outstanding borrowings of $1.188 billion under our revolving bank credit facility.

25

The Notes will be unsecured obligations of the Company. Secured debt and other secured obligations of the Company and the Subsidiary Guarantors (including obligations with respect to our revolving bank credit facility) will be effectively senior to the Notes to the extent of the value of the assets securing such debt or other obligations.

Liabilities of Subsidiaries versus Notes. A substantial portion of the Company’s operations is conducted through its subsidiaries. Claims of creditors of any subsidiaries that are not Subsidiary Guarantors, including trade creditors and creditors holding indebtedness or guarantees issued by such subsidiaries, and claims of preferred stockholders of such subsidiaries will have priority with respect to the assets and earnings of such subsidiaries over the claims of the Company’s creditors, including holders of the Notes. Accordingly, the Notes will be effectively subordinated to creditors (including trade creditors) and preferred stockholders, if any, of the Company’s subsidiaries that are not Subsidiary Guarantors. As of the Issue Date, all of the Company’s existing domestic subsidiaries and one of the Company’s foreign subsidiaries will be Subsidiary Guarantors.

Although the Indenture limits the incurrence of certain secured Indebtedness of Company’s subsidiaries, such limitations are subject to a number of significant qualifications and the Indenture does not limit the incurrence of unsecured Indebtedness.

Make-Whole Redemption

At any time prior to the Maturity Date, the Company may, at its option, redeem all or any portion of the Notes at the Make-Whole Price plus accrued and unpaid interest to the date of redemption.

Certain Covenants

The following restrictive covenants will be applicable to the Company and its Subsidiaries.

Limitation on Liens. The Company will not, and will not permit any Subsidiary to, create, incur or assume any Indebtedness secured by any Liens (other than Permitted Liens) upon any of the properties of the Company or any Subsidiary, unless the Notes or a Guarantee are equally and ratably secured; provided that if such Indebtedness is expressly subordinated to the Notes or a Guarantee, the Lien securing such Indebtedness will be subordinated and junior to the Lien securing the Notes or such Guarantee.

Limitation on Sale/Leaseback Transactions. The Company will not, and will not permit any Subsidiary to, enter into any Sale/Leaseback Transaction with any Person (other than the Company or any other Subsidiary) unless:

(1) the Company or such Subsidiary would be entitled to incur secured Indebtedness, in a principal amount equal to the Attributable Indebtedness with respect to such Sale/Leaseback Transaction in accordance with the covenant captioned “—Limitation on Liens”; or

(2) the Company or such Subsidiary receives proceeds from such Sale/Leaseback Transaction at least equal to the fair market value thereof (as determined in good faith by the Company’s Board of Directors, whose determination in good faith, evidenced by a resolution of such Board, shall be conclusive) and such proceeds are applied in accordance with the following two paragraphs:

The Company may apply Net Available Proceeds from such Sale/Leaseback Transaction, within 365 days following the receipt of Net Available Proceeds from the Sale/Leaseback Transaction, to:

(1) the repayment of Indebtedness of the Company or a Subsidiary under Credit Facilities or other Senior Indebtedness, including any mandatory redemption or repurchase or make-whole redemption of the Existing Notes or the Notes;

(2) make an Investment in assets used in the Oil and Gas Business; or

(3) develop by drilling the Company’s oil and gas reserves.

26

If, upon completion of the 365-day period, any portion of the Net Available Proceeds shall not have been applied by the Company as described in clauses (1), (2) or (3) in the immediately preceding paragraph and such remaining Net Available Proceeds, together with any remaining net cash proceeds from any prior Sale/Leaseback Transaction (such aggregate constituting “Excess Proceeds”), exceed $40 million, then the Company will be obligated to make an offer (the “Net Proceeds Offer”) to purchase the Notes and any other Senior Indebtedness in respect of which such an offer to purchase is also required to be made concurrently with the Net Proceeds Offer having an aggregate principal amount equal to the Excess Proceeds (such purchase to be made on a pro rata basis if the amount available for such repurchase is less than the principal amount of the Notes and other such Senior Indebtedness tendered in such Net Proceeds Offer) at a purchase price of 100% of the principal amount thereof plus accrued interest to the date of repurchase. Upon the completion of the Net Proceeds Offer, the amount of Excess Proceeds will be reset to zero.

Within 15 days after the Company becomes obligated to make a Net Proceeds Offer (a “Net Proceeds Offer Triggering Event”), the Company will mail or cause to be mailed to all Holders on the date of the Net Proceeds Offer Triggering Event a notice (the “Offer Notice”) of the occurrence of such Net Proceeds Offer Triggering Event and of the Holders’ rights arising as a result thereof. The Offer Notice shall state, among other things:

(1) that the offer is being made pursuant to this covenant;

(2) that any Note not tendered will continue to accrue interest;

(3) that any Note accepted for payment pursuant to the offer shall cease to accrue interest on the payment date; and

(4) the instructions, consistent with this covenant, that a Holder must follow in order to have such Holder’s Notes purchased.

The Net Proceeds Offer will be deemed to have commenced upon mailing of the Offer Notice and will terminate 20 business days after its commencement, unless a longer offering period is required by law. Promptly after the termination of the offer, the Company will purchase and mail or deliver payment for all Notes tendered in response to the offer.

On the payment date, the Company will, to the extent lawful, (a) accept for payment Notes or portions thereof tendered pursuant to the Net Proceeds Offer, (b) deposit with the paying agent an amount equal to the payment in respect of all Notes or portions thereof so tendered and (c) deliver to the Trustee the Notes so accepted together with an officers’ certificate stating the Notes or portions thereof tendered to the Company. The paying agent will promptly mail or deliver to each Holder of Notes so accepted payment in an amount equal to the purchase price for such Notes, and the Trustee will promptly authenticate and mail or deliver 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 comply with Section 14 of the Exchange Act and the provisions of Regulation 14E and any other tender offer rules under the Exchange Act and any other federal and state securities laws, rules and regulations which may then be applicable to any Net Proceeds Offer.

During the period between any Sale/Leaseback Transaction and the application of the Net Available Proceeds therefrom in accordance with this covenant, all Net Available Proceeds shall be maintained in a segregated account and shall be invested in Permitted Financial Investments.

Limitations on Mergers and Consolidations. The Company will not consolidate or merge with or into any Person, or sell, convey, lease or otherwise dispose of all or substantially all of its assets to any Person, unless:

(1) the Person formed by or surviving such consolidation or merger (if other than the Company), or to which such sale, lease, conveyance or other disposition shall be made (collectively, the “Successor”), is a

27

corporation, limited liability company or limited partnership organized and existing under the laws of the United States or any state thereof or the District of Columbia, or Canada or any province thereof, and the Successor assumes by supplemental indenture in a form satisfactory to the Trustee all of the obligations of the Company under the Indenture and under the Notes; provided, that unless the Successor is a corporation, a corporate co-issuer of the Notes will be added to the Indenture by such supplemental indenture; and

(2) immediately before and after giving effect to such transaction, no Event of Default shall have occurred and be continuing.

SEC 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, the Company will file with the SEC and provide the Trustee and Holders with annual reports and such information, documents and other reports specified in Sections 13 and 15(d) of the Exchange Act.

(2) the capitalized costs that are attributable to oil and gas properties of the Company and its Subsidiaries to which no proved oil and gas reserves are attributable, based on the Company’s books and records as of a date no earlier than the date of the Company’s latest annual or quarterly financial statements,

As used in the preceding sentence, the “net amount of rent” under any lease for any such period shall mean the sum of rental and other payments required to be paid with respect to such period by the lessee thereunder excluding any amounts required to be paid by such lessee on account of maintenance and repairs, insurance, taxes, assessments, water rates or similar charges. In the case of any lease which is terminable by the lessee upon payment of a penalty, such net amount of rent shall also include the amount of such penalty, but no rent shall be considered as required to be paid under such lease subsequent to the first date upon which it may be so terminated.

“Average Life” means, as of the date of determination, with respect to any Indebtedness, the quotient obtained by dividing (a) the product of (x) the number of years from such date to the date of each successive scheduled principal payment of such Indebtedness multiplied by (y) the amount of such principal payment by (b) the sum of all such principal payments.

Events of Default

The following will be Events of Default with respect to the Notes:

(1) default by the Company or any Subsidiary Guarantor in the payment of principal of or premium, if any, on the Notes when due and payable at maturity, upon repurchase pursuant to the covenant described under “Limitation on Sale/Leaseback Transactions”, upon acceleration or otherwise;

(2) default by the Company or any Subsidiary Guarantor for 30 days in payment of any interest on the Notes;

(3) default by the Company or any Subsidiary Guarantor in the deposit of any make-whole redemption payment;

(4) default on any other Indebtedness of the Company, any Subsidiary Guarantor or any other Subsidiary if either

(A) such default results in the acceleration of the maturity of any such Indebtedness having a principal amount of $50.0 million or more individually or, taken together with the principal amount of any other such Indebtedness the maturity of which has been so accelerated, in the aggregate, or

(B) such default results from the failure to pay when due principal of, premium, if any, or interest on, any such Indebtedness, after giving effect to any applicable grace period (a “Payment Default”), having a principal amount of $50.0 million or more individually or, taken together with the principal amount of any other Indebtedness under which there has been a Payment Default, in the aggregate;

provided that if any such default is cured or waived or any such acceleration is rescinded, or such Indebtedness is repaid, within a period of 30 days from the continuation of such default beyond any applicable grace period or the occurrence of such acceleration, as the case may be, such Event of Default and any consequent acceleration of the Notes shall be rescinded, so long as any such rescission does not conflict with any judgment or decree or applicable provision of law;

(5) default in the performance, or breach of, the covenant set forth in the covenant captioned “Limitations on Mergers and Consolidations,” or in the performance, or breach of, any other covenant or agreement of the Company or any Subsidiary Guarantor in the Indenture and failure to remedy such default within a period of 45 days after written notice thereof from the Trustee or Holders of 25% of the principal amount of the outstanding Notes;

(6) the entry by a court of one or more judgments or orders for the payment of money against the Company, any Subsidiary Guarantor or any other Subsidiary in an aggregate amount in excess of $50.0 million (net of applicable insurance coverage by a third party insurer which is acknowledged in writing by such insurer) that has not been vacated, discharged, satisfied or stayed pending appeal within 60 days from the entry thereof;

(7) the failure of a Guarantee by a Subsidiary Guarantor to be in full force and effect, or the denial or disaffirmance by such entity thereof; or

(8) certain events involving bankruptcy, insolvency or reorganization of the Company or any Subsidiary of the Company.

The Indenture provides that the Trustee may withhold notice to the Holders of the Notes of any default (except in payment of principal of, or premium, if any, or interest on the Notes) if the Trustee considers it in the interest of the Holders of the Notes to do so.

If an Event of Default occurs and is continuing, the Trustee or the Holders of not less than 25% in principal amount of the Notes outstanding may declare the principal of and premium, if any, and accrued but unpaid

37

interest on all the Notes to be due and payable. Upon such a declaration, such principal, premium, if any, and interest will be due and payable immediately. If an Event of Default relating to certain events of bankruptcy, insolvency or reorganization of the Company or any Subsidiary of the Company occurs and is continuing, the principal of, and premium, if any, and interest on all the Notes will become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders of the Notes. The amount due and payable on the acceleration of any Note will be equal to 100% of the principal amount of the Note, plus accrued and unpaid interest to the date of payment. Under certain circumstances, the Holders of a majority in principal amount of the outstanding Notes may rescind any such acceleration with respect to the Notes and its consequences.

No Holder of a Note may pursue any remedy under the Indenture unless

(1) the Trustee shall have received written notice of a continuing Event of Default,

(2) the Trustee shall have received a request from Holders of at least 25% in principal amount of the Notes to pursue such remedy,

(3) the Trustee shall have been offered indemnity reasonably satisfactory to it,

(4) the Trustee shall have failed to act for a period of 60 days after receipt of such notice, request and offer of indemnity and

(5) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Notes;

provided, however, such provision does not affect the right of a Holder of any Note to sue for enforcement of any overdue payment thereon.

The Holders of a majority in principal amount of the Notes then outstanding will have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee, subject to certain limitations specified in the Indenture. The Indenture requires the annual filing by the Company with the Trustee of a written statement as to compliance with the covenants contained in the Indenture.

Modification and Waiver

Supplements and amendments to the Indenture or the Notes may be made by the Company, the Subsidiary Guarantors and the Trustee with the consent of the Holders of a majority in principal amount of the Notes then outstanding; provided that no such modification or amendment may, without the consent of the Holder of each Note then outstanding affected thereby,

(1) reduce the percentage of principal amount of Notes whose Holders must consent to an amendment or supplement;

(2) reduce the rate or change the time for payment of interest, including default interest, on any Note;

(3) reduce the principal amount of any Note or change the Maturity Date;

(4) reduce the redemption price, including premium, if any, payable upon redemption of any Note or change the time at which any Note may or shall be redeemed;

(5) reduce the purchase price payable upon the repurchase of any Note in connection with a Net Proceeds Offer, or change the time at which any Note may or shall be repurchased thereunder;

(6) make any Note payable in money other than that stated in such Note;

(7) impair the right to institute suit for the enforcement of any payment of principal of, or premium, if any, or interest on, any Note;

(8) make any change in the percentage of principal amount of Notes necessary to waive compliance with certain provisions of the Indenture; or

38

(9) waive a continuing Default or Event of Default in the payment of principal of, premium, if any, or interest on the Notes.

Supplements and amendments of the Indenture may be made by the Company and the Trustee without the consent of any Holders of the Notes in certain limited circumstances, including

(a) to cure any ambiguity, omission, defect or inconsistency,

(b) to provide for the assumption of the obligations of the Company or any Subsidiary Guarantor under the Indenture upon the merger, consolidation or sale or other disposition of all or substantially all of the assets of the Company or such Subsidiary Guarantor,

(c) to reflect the release of any Subsidiary Guarantor from its Guarantee of the Notes, or the addition of any Subsidiary of the Company as a Subsidiary Guarantor, in the manner provided in the Indenture,

(d) to comply with any requirement of the SEC in order to effect or maintain the qualification of the Indenture under the Trust Indenture Act or

(e) to make any change that would provide any additional benefit to the Holders or that does not adversely affect the rights of any Holder of the Notes in any material respect.

The Holders of a majority in aggregate principal amount of the Notes then outstanding may waive any past default under the Indenture, except a default in the payment of principal, premium, if any, or interest.

Legal Defeasance and Covenant Defeasance

The Company may, at its option and at any time, elect to have its obligations discharged with respect to the outstanding Notes (“Legal Defeasance”). Such Legal Defeasance means that the Company will be deemed to have paid and discharged the entire Indebtedness represented by such Notes, except for

(1) the rights of Holders of the Notes to receive payments solely from the trust fund described in the following paragraph in respect of the principal of, premium, if any, and interest on the Notes when such payments are due,

(2) the Company’s obligations with respect to the Notes concerning the issuance of temporary Notes, transfers and exchanges of the Notes, replacement of mutilated, destroyed, lost or stolen Notes, the maintenance of an office or agency where the Notes may be surrendered for transfer or exchange or presented for payment, and duties of paying agents,

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

(4) the Legal Defeasance provisions of the Indenture.

In addition, the Company may, at its option and at any time, elect to have the obligations of the Company released with respect to certain covenants described under “—Certain Covenants” (“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) described under “—Events of Default” will no longer constitute an Event of Default. If we exercise our Legal Defeasance or Covenant Defeasance option, each Subsidiary Guarantor will be released from all its obligations under the Indenture and its Guarantee.

In order to exercise either Legal Defeasance or Covenant Defeasance under the Indenture,

(1) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of the Notes, cash in U.S. Legal Tender, U.S. Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public

39

accountants, to pay the principal of, premium, if any, and interest on the outstanding amount of the Notes on the Maturity Date or on the applicable mandatory redemption date, as the case may be, of such principal or installment of principal, premium, if any, or interest;

(2) in the case of Legal Defeasance, the Company must deliver to the Trustee an opinion of counsel reasonably acceptable to the Trustee confirming that

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

(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 Notes will not recognize income, gain or loss for U.S. Federal income tax purposes as a result of such Legal Defeasance and will be subject to U.S. Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

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

(4) no Default or Event of Default shall have occurred and be continuing on the date of such deposit or insofar as Events of Default from bankruptcy or insolvency events are concerned, at any time in the period ending on the 91st day after the date of deposit;

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

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

(7) the Company shall have delivered to the Trustee an officers’ certificate and an opinion of counsel each stating that the Company has complied with all conditions precedent provided for relating to the Legal Defeasance or the Covenant Defeasance.

Governing Law

The Indenture provides that it and the Notes will be governed by, and construed in accordance with, the laws of the State of New York.

The Trustee

The Bank of New York Trust Company, N.A. is the Trustee under the Indenture. The Bank of New York Trust Company, N.A. also serves as trustee for our 7.5% Senior Notes due 2013, our 7% Senior Notes due 2014, our 7.5% Senior Notes due 2014, our 7.75% Senior Notes due 2015, our 6.375% Senior Notes due 2015, our 6.875% Senior Notes due 2016, our 6.625% Senior Notes due 2016, our 6.5% Senior Notes due 2017, our 6.25% Senior Notes due 2018, our 6.875% Senior Notes due 2020 and our 2.75% Contingent Convertible Senior Notes due 2035. We may also maintain banking and other commercial relationships with the Trustee and its affiliates in the ordinary course of business, and the Trustee may own our debt securities. The Trustee’s address is 2 North LaSalle Street, Suite 1020, Chicago, Illinois 60602. The Company has also appointed the Trustee as the initial registrar and paying agent under the Indenture.

40

The Trustee is permitted to become an owner or pledgee of the Notes and may otherwise deal with the Company or its Subsidiaries or Affiliates with the same rights it would have if it were not Trustee. If, however, the Trustee acquires any conflicting interest (as defined in the Trust Indenture Act) after an Event of Default has occurred and is continuing, it must eliminate such conflict or resign.

In case an Event of Default shall occur (and be continuing), the Trustee will be required to use the degree of care and skill of a prudent person in the conduct of such person’s own affairs. The Trustee will be under no obligation to exercise any of its powers under the Indenture at the request of any of the Holders of the Notes, unless such Holders have offered the Trustee indemnity reasonably satisfactory to it.

Book Entry, Delivery and Form

The Notes sold will be issued in the form of one or more global securities. The global securities will be deposited with, or on behalf of, the Depositary and registered in the name of the Depositary or its nominee. Except as set forth below, the global securities may be transferred, in whole and not in part, only to the Depositary or another nominee of the Depositary. Investors may hold their beneficial interests in the global securities directly through the Depositary if they have an account with the Depositary or indirectly through organizations which have accounts with the Depositary.

Notes that are issued as described below under “—Certificated Notes” will be issued in definitive form. Upon the transfer of Notes in definitive form, such Notes will, unless the global securities have previously been exchanged for Notes in definitive form, be exchanged for an interest in the global securities representing the aggregate principal amount of Notes being transferred.

The Depositary has advised the Company as follows: The Depositary is a limited-purpose trust company organized under the laws of the State of New York, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code, and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. The Depositary was created to hold securities of institutions that have accounts with the Depositary (“participants”) and to facilitate the clearance and settlement of securities transactions among its participants in such securities through electronic book-entry changes in accounts of the participants, thereby eliminating the need for physical movement of securities certificates. The Depositary’s participants include securities brokers and dealers (which may include the underwriters), banks, trust companies, clearing corporations and certain other organizations. Access to the Depositary’s book-entry system is also available to others such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a participant, whether directly or indirectly.

The Company expects that pursuant to procedures established by the Depositary, upon the issuance of the global securities, the Depositary will credit, on its book-entry registrations and transfer system, the aggregate principal amount of Notes represented by such global securities to the accounts of participants. The accounts to be credited shall be designated by the underwriter of the Notes. Ownership of beneficial interests in the global securities will be limited to participants or Persons that may hold interests through participants. Ownership of beneficial interests in the global securities will be shown on, and the transfer of those ownership interests will be effected only through, records maintained by the Depositary (with respect to participants’ interest) and such participants (with respect to the owners of beneficial interests in the global securities other than participants). The laws of some jurisdictions may require that certain purchasers of securities take physical delivery of such securities in definitive form. Such limits and laws may impair the ability to transfer or pledge beneficial interests in the global securities.

So long as the Depositary, or its nominee, is the Holder of the global securities, the Depositary or such nominee, as the case may be, will be considered the sole legal owner and Holder of the Notes for all purposes of the Notes and the Indenture. Except as set forth below, you will not be entitled to have the Notes represented by the global securities registered in your name, will not receive or be entitled to receive physical delivery of

41

certificated Notes in definitive form and will not be considered to be the owner or Holder of any Notes under the global securities. The Company understands that under existing industry practice, in the event an owner of a beneficial interest in the global securities desires to take any action that the Depositary, as the Holder of the global securities, is entitled to take, the Depositary will authorize the participants to take such action, and that the participants will authorize beneficial owners owning through such participants to take such action or would otherwise act upon the instructions of beneficial owners owning through them.

The Company will make all payments on Notes represented by the global securities registered in the name of and held by the Depositary or its nominee to the Depositary or its nominee, as the case may be, as the owner and Holder of the global securities.

The Company expects that the Depositary or its nominee, upon receipt of any payment in respect of the global securities, will credit participants’ accounts with payments in amounts proportionate to their respective beneficial interests in the aggregate principal amount of the global securities as shown on the records of the Depositary or its nominee. The Company also expects that payments by participants to owners of beneficial interest in the global securities held through such participants will be governed by standing instructions and customary practices and will be the responsibility of such participants. The Company will not have any responsibility or liability for any aspect of the records relating to, or payments made on account of, beneficial ownership interests in the global securities for any Notes or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests or for any other aspect of the relationship between the Depositary and its participants or the relationship between such participants and the owners of beneficial interests in the global securities owning through such participants.

Although the Depositary has agreed to the foregoing procedures in order to facilitate transfers of interests in the global securities among participants of the Depositary, it is under no obligations to perform or continue to perform such procedures, and such procedures may be discontinued at any time. Neither the Trustee nor the Company will have any responsibility for the performance by the Depositary or its participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

Certificated Notes

Subject to certain conditions, the Notes represented by the global securities will be exchangeable for certificated Notes in definitive form of like tenor as such Notes if:

(1) the Depositary notifies the Company that it is unwilling or unable to continue as Depositary for the global securities and a successor is not promptly appointed or if at any time the Depositary ceases to be a clearing agency registered under the Exchange Act or

(2) the Company in its discretion at any time determines not to have all of the Notes represented by the global securities.

Any Notes that are exchangeable pursuant to the preceding sentence will be exchanged for certificated Notes issuable in authorized denominations and registered in such names as the Depositary shall direct. Subject to the foregoing, the global securities are not exchangeable, except for global securities of the same aggregate denominations to be registered in the name of the Depositary or its nominee.

The following is a summary of certain of our indebtedness that will be outstanding following the consummation of this offering. To the extent this summary contains descriptions of our revolving bank credit facility, our 7.5% Senior Notes due 2013, our 7% Senior Notes due 2014, our 7.5% Senior Notes due 2014, our 7.75% Senior Notes due 2015, our 6.375% Senior Notes due 2015, our 6.875% Senior Notes due 2016, our 6.625% Senior Notes due 2016, our 6.5% Senior Notes due 2017, our 6.25% Senior Notes due 2018, our 6.875% Senior Notes due 2020 and our 2.75% Contingent Convertible Senior Notes due 2035, and the indentures governing them, the descriptions do not purport to be complete and are qualified in their entirety by reference to those and related documents, copies of which we will provide you upon request.

Our Revolving Bank Credit Facility

Our revolving bank credit facility limits our borrowings to the lesser of the borrowing base (currently $2.5 billion) and the total commitments (currently $2.0 billion) and matures in January 2011. As of June 23, 2006, we had outstanding borrowings of $1.188 billion under this facility and had $5.1 million of the facility securing various letters of credit. Borrowings under the facility are collateralized by some of our producing oil and gas properties and bear interest at either (i) the greater of the reference rate of Union Bank of California N.A. or the federal funds effective rate plus 0.50% or (ii) the London Interbank Offered Rate (LIBOR), at our option, plus a margin that varies based on our senior unsecured long-term debt ratings. The collateral value and borrowing base are determined periodically. The unused portion of the facility is subject to an annual commitment fee that also varies according to our senior unsecured long-term debt ratings. As of March 31, 2006, the annual commitment fee rate was 0.25%. Interest is payable quarterly or, if LIBOR applies, it may be payable at more frequent intervals. The credit agreement contains various covenants and restrictive provisions, including those restricting our ability to incur additional indebtedness, make investments or loans and create liens. The credit agreement requires us to maintain an indebtedness to EBITDA ratio (as defined in the credit agreement) not to exceed 3.5 to 1 and an indebtedness to total capitalization ratio (as defined in the credit agreement) not to exceed 0.65 to 1.

Our Senior Notes

At March 31, 2006, we had outstanding senior notes in an aggregate principal amount of $6.0 billion, which represented the remainder of our long-term debt. At the date of this prospectus, we have issued and outstanding $363.8 million in principal amount of 7.5% Senior Notes due 2013, $300.0 million in principal amount of 7% Senior Notes due 2014, $300.0 million in principal amount of 7.5% Senior Notes due 2014, $300.4 million in principal amount of 7.75% Senior Notes due 2015, $600.0 million in principal amount of 6.375% Senior Notes due 2015, $670.4 million in principal amount of 6.875% Senior Notes due 2016, $600.0 million principal amount of 6.625% Senior Notes due 2016, $1.1 billion principal amount of 6.5% Senior Notes due 2017, $600.0 million principal amount of 6.25% Senior Notes due 2018 and $500.0 million principal amount of 6.875% Senior Notes due 2020. There are no scheduled principal payments required on any of these senior notes until their final maturities.

Our outstanding senior notes are senior, unsecured obligations that rank pari passu in right of payment with all of our existing and future senior indebtedness, including the notes offered hereby, and rank senior in right of payment to all of our future subordinated indebtedness. Our outstanding notes are fully and unconditionally guaranteed, jointly and severally, by certain of our domestic subsidiaries and one of our foreign subsidiaries.

Our existing senior note indentures (other than the indentures governing the 6.50% Senior Notes due 2017 and the 6.875% Senior Notes due 2020) restrict our and our restricted subsidiaries’ ability to incur additional indebtedness. Please read “Risk Factors—Risks Relating to Our Business—Lower oil and natural gas prices could negatively impact our ability to borrow.” As of March 31, 2006, we estimate that secured bank indebtedness of $3.4 billion could have been incurred within those restrictions. These restrictions under such indentures will not apply to

43

any future unrestricted subsidiaries. There are no unrestricted subsidiaries under our indentures as of the date of this prospectus.

Our existing senior note indentures (other than the indentures governing the 6.50% Senior Notes due 2017 and the 6.875% Senior Notes due 2020) also limit our ability to make restricted payments, including the payment of cash dividends, unless certain tests are met.

We also have issued and outstanding $690 million aggregate principal amount of 2.75% Contingent Convertible Senior Notes due 2035 (the “Convertible Senior Notes”). The Convertible Senior Notes are senior unsecured obligations and rank pari passu in right of payment to all of our existing and future senior indebtedness, including the notes offered hereby, and rank senior in right of payment to all of our future subordinated indebtedness. The Convertible Senior Notes are guaranteed by certain of our existing domestic subsidiaries and one of our foreign subsidiaries and by certain of our future domestic subsidiaries on a senior unsecured basis. The indenture governing the Convertible Senior Notes does not have any financial or restricted payment covenants.

The Convertible Senior Notes will be convertible, at the holder’s option, prior to the maturity date under certain circumstances, using a net share settlement process, into cash and, in some circumstances, our common stock. In general, upon conversion of a Convertible Senior Note, the holder of such note will receive cash equal to the principal amount of the note and common stock for the note’s conversion value in excess of such principal amount.

In addition, we will pay contingent interest on the Convertible Senior Notes during any six-month interest period, beginning with the six-month period ending May 14, 2016, under certain conditions.

The Convertible Senior Notes will mature on November 15, 2035. We may redeem the Convertible Senior Notes, in whole at any time, or in part from time to time, on or after November 15, 2015 at a redemption price, payable in cash, of 100% of the principal amount of such notes, plus accrued and unpaid interest.

Holders of the Convertible Senior Notes may require us to repurchase all or a portion of their notes on November 15, 2015, 2020, 2025 and 2030 at 100% of the principal amount of the notes, plus accrued and unpaid interest, payable in cash. Upon a fundamental change, as defined in the indenture governing the Convertible Senior Notes, holders may require us to repurchase all or a portion of their notes, payable in cash equal to 100% of the principal amount of the notes plus accrued and unpaid interest.

MATERIAL UNITED STATES FEDERAL TAX CONSIDERATIONS

General

The following discussion summarizes the material U.S. Federal income and certain estate tax consequences of the purchase, ownership and disposition of the notes by an initial holder of the notes who purchases the notes for cash at the original offering price, who holds the notes as capital assets and who does not have a special tax status. This discussion is based upon the Internal Revenue Code of 1986, as amended (the “Code”), Treasury Regulations, and judicial decisions and administrative interpretations thereunder, as of the date hereof, all of which are subject to change, possibly with retroactive effect, or are subject to different interpretations. We cannot assure you that the Internal Revenue Service (the “IRS”) will not challenge one or more of the tax consequences described herein, and we have not obtained, nor do we intend to obtain, a ruling from the IRS or an opinion of counsel with respect to the U.S. Federal tax consequences of purchasing, owning or disposing of the notes.

In this discussion, we do not purport to address all tax considerations that may be important to a particular holder in light of the holder’s circumstances, or to certain categories of investors (such as financial institutions, insurance companies, tax-exempt organizations, dealers in securities, persons who hold the notes through partnerships or other pass-through entities, regulated investment companies, U.S. persons whose functional currency is not the U.S. dollar, U.S. expatriates or persons who hold the notes as part of a hedge, conversion transaction, straddle or other risk reduction transaction) that may be subject to special rules. This discussion also does not address the tax considerations arising under the laws of any foreign, state or local jurisdiction.

If a partnership (including an entity treated as a partnership for U.S. Federal income tax purposes) holds notes, the tax treatment of a partner generally will depend upon the status of the partner and upon the activities of the partnership. If you are a partner of a partnership holding notes, we suggest that you consult your tax advisor.

YOU SHOULD CONSULT YOUR OWN TAX ADVISORS AS TO THE PARTICULAR TAX CONSEQUENCES TO YOU OF THE ACQUISITION, OWNERSHIP AND DISPOSITION OF THE NOTES, INCLUDING THE EFFECT AND APPLICABILITY OF STATE, LOCAL OR FOREIGN TAX LAWS.

Consequences to U.S. Holders

You are a U.S. holder for purposes of this discussion if you are a beneficial owner of notes and you are:

• an individual U.S. citizen or resident alien;

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

• an estate whose world-wide income is subject to U.S. Federal income taxation; or

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

Interest on the Notes

Stated interest on a note will be includible in your gross income as ordinary interest income in accordance with your usual method of accounting for tax purposes. We do not intend to treat the possibility of the payment of additional amounts described in “Description of Notes—Make-Whole Redemption,” as (i) affecting the determination of the yield to maturity of the notes, or (ii) giving rise to original issue discount or recognition of ordinary income on the sale, exchange or redemption of the notes. As a result, any additional amounts received should be treated as ordinary income at the time such amounts accrue or are received in accordance with your

45

method of accounting. It is possible, however, that the IRS may take a different position, in which case the timing and amount of income inclusions by a U.S. holder may be affected.

Sale, Exchange, Redemption or Other Disposition of the Notes

Upon the disposition of a note by sale, exchange, redemption or other disposition, you generally will recognize capital gain or loss equal to the difference between (i) the amount realized on the disposition (other than amounts attributable to accrued interest not previously recognized as income, which will be treated as ordinary interest income as described above) and (ii) your adjusted federal income tax basis in the note. Your adjusted federal income tax basis in a note generally will equal the cost of the note to you. Any capital gain or loss will be long-term capital gain or loss if you have held the note for longer than one year. You should consult your tax advisors regarding the treatment of capital gains (which may be taxed at lower rates than ordinary income for certain noncorporate taxpayers) and losses (the deductibility of which is subject to certain limitations).

Consequences to Non-U.S. Holders

You are a non-U.S. holder for purposes of this discussion if you are a beneficial owner of notes (other than an entity treated as a partnership for U.S. federal income tax purposes) and you are not a U.S. holder.

U.S. Federal Withholding Tax

The 30% U.S. Federal withholding tax generally will not apply to any payment of principal or interest on the notes under the portfolio interest exemption provided that:

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

• you are not a controlled foreign corporation that is related to us through stock ownership; and

• you are not a bank whose receipt of interest on the notes is pursuant to a loan agreement entered into in the ordinary course of business.

The exemption from withholding tax will not apply unless (a) you provide your name and address on an IRS Form W-8BEN (or successor form), and certify under penalties of perjury, that you are not a United States person, (b) a financial institution holding the notes on your behalf certifies, under penalties of perjury, that it has received an IRS Form W-8BEN (or successor form) from you and must provide us with a copy, or (c) you hold your notes directly through a “qualified intermediary,” and the qualified intermediary has sufficient information in its files indicating that you are not a U.S. holder. A qualified intermediary is a bank, broker or other intermediary that is acting out of a non-U.S. branch or office and has signed an agreement with the IRS providing that it will administer all or part of the U.S. Federal tax withholding rules under specified procedures.

If you cannot satisfy the requirements described above, payments of principal and interest made to you will be subject to the 30% U.S. Federal withholding tax, unless you provide us with a properly executed (1) IRS Form W-8BEN or successor form claiming an exemption from or a reduction of withholding under the benefit of a tax treaty or (2) IRS Form W-8ECI (or successor form) stating that interest paid on the notes is not subject to withholding tax because it is effectively connected with your conduct of a trade or business in the United States.

U.S. Federal Income Tax

Interest. If you are engaged in a trade or business in the United States and interest on the notes is effectively connected with the conduct of that trade or business (and, in the case of an applicable tax treaty, is attributable to a U.S. permanent establishment maintained by you), you will be subject to U.S. Federal income tax on the

46

interest on a net income basis (although exempt from the 30% withholding tax) in the same manner as if you were a United States person as defined under the Code. In addition, if you are a foreign corporation, you may be subject to a branch profits tax equal to 30% (or lower applicable treaty rate) of your earnings and profits for the taxable year, including earnings and profits from an investment in the notes, that are effectively connected with the conduct by you of a trade or business in the United States.

Sale, Exchange, Redemption or Other Disposition of the Notes. Any gain or income realized on the sale, exchange, redemption or other disposition of the notes generally will not be subject to U.S. Federal income tax unless:

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

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

• the gain represents accrued interest, in which case the rules for taxation of interest would apply.

If you are a holder subject to U.S. Federal income tax under the first bullet point, you will be taxed on a net income basis in the same manner as if you were a United States person as defined under the Code. In addition, if you are a foreign corporation, you may be subject to a branch profits tax as explained above. Holders subject to U.S. Federal income tax under the second bullet point will be taxed on the net gain at a 30% rate.

U.S. Federal Estate Tax

Your estate will not be subject to U.S. Federal estate tax on notes beneficially owned by you at the time of your death, provided that (1) interest on the notes is exempt from U.S. Federal withholding tax under the portfolio interest exemption (without regard to the certification requirement) described in the first paragraph of “—Consequences to Non-U.S. Holders—U.S. Federal Withholding Tax” above and (2) interest on such notes would not have been, if received at the time of your death, effectively connected with the conduct by you of a trade or business in the United States.

Backup Withholding and Information Reporting

U.S. Holders

Information reporting will apply to payments of principal and interest made by us on, or the proceeds of the sale or other disposition of, the notes with respect to certain noncorporate U.S. holders, and backup withholding, currently at a rate of 28%, may apply unless the recipient of such payment provides the appropriate intermediary with a taxpayer identification number, certified under penalties of perjury, as well as certain other information or otherwise establishes an exemption from backup withholding. Any amount withheld under the backup withholding rules is allowable as a credit against the U.S. holder’s U.S. Federal income tax liability, provided the required information is timely provided to the IRS.

Non-U.S. Holders

Payments to non-U.S. holders of interest on a note and amounts withheld from such payments, if any, generally will be reported to the IRS and you. Backup withholding will not apply to payments of principal and interest on the notes if you certify as to your non-U.S. holder status on an IRS Form W-8BEN (or successor form) under penalties of perjury or you otherwise qualify for an exemption (provided that neither we nor our agent know or have reason to know that you are a United States person or that the conditions of any other exemptions are not in fact satisfied).

The payment of the proceeds of the disposition of notes to or through the U.S. office of a U.S. or foreign broker will be subject to information reporting and backup withholding unless you provide the certification

47

described above or you otherwise qualify for an exemption. The proceeds of a disposition effected outside the United States by a non-U.S. holder to or through a foreign office of a broker generally will not be subject to backup withholding or information reporting. However, if such broker is a United States person, a controlled foreign corporation, a foreign person 50% or more of whose gross income from all sources for certain periods is effectively connected with a trade or business in the United States, or a foreign partnership that is engaged in the conduct of a trade or business in the United States or that has one or more partners that are United States persons who in the aggregate hold more than 50% of the income or capital interests in the partnership, information reporting requirements will apply unless such broker has documentary evidence in its files of the holder’s non-U.S. status and has no actual knowledge or reason to know to the contrary or unless the holder otherwise qualifies for an exemption. Any amount withheld under the backup withholding rules is allowable as a credit against your U.S. Federal income tax liability, if any, provided the required information or appropriate claim for refund is provided to the IRS.

UNDERWRITING

We and the underwriters for the offering named below have entered into an underwriting agreement with respect to the notes. Subject to certain conditions, each underwriter has severally agreed to purchase the principal amount of notes indicated in the following table.

Underwriters	Principal Amount of Notes
Banc of America Securities LLC	$
Deutsche Bank Securities Inc.
Goldman, Sachs & Co.
Lehman Brothers Inc.
Wachovia Capital Markets, LLC
ABN AMRO Incorporated
BNP Paribas Securities Corp.
Calyon Securities (USA) Inc.

HVB Capital Markets, Inc.
Piper Jaffray & Co.
TD Securities (USA) LLC
Wedbush Morgan Securities Inc.
Total	$	500,000,000

The underwriters are committed to take and pay for all of the notes being offered, if any are taken.

Notes sold by the underwriters to the public will initially be offered at the initial public offering price set forth on the cover of this prospectus. Any notes sold by the underwriters to securities dealers may be sold at a discount from the initial public offering price of up to         % of the principal amount of notes. Any such securities dealers may resell any notes purchased from the underwriters to certain other brokers or dealers at a discount from the initial public offering price of up to         % of the principal amount of notes. If all the notes are not sold at the initial offering price, the underwriters may change the offering price and the other selling terms.

The notes are a new issue of securities with no established trading market. We have been advised by the underwriters that the underwriters intend to make a market in the notes but are not obligated to do so and may discontinue market making at any time without notice. No assurance can be given as to the liquidity of the trading market for the notes.

In connection with the offering, the underwriters may purchase and sell notes in the open market. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater number of notes than they are required to purchase in the offering. Stabilizing transactions consist of certain bids or purchases made for the purpose of preventing or retarding a decline in the market price of the notes while the offering is in progress.

49

The underwriters also may impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the representatives have repurchased notes sold by or for the account of such underwriter in stabilizing or short covering transactions.

These activities by the underwriters, as well as other purchases by the underwriters for their own accounts, may stabilize, maintain or otherwise affect the market price of the notes. As a result, the price of the notes may be higher than the price that otherwise might exist in the open market. If these activities are commenced, they may be discontinued by the underwriters at any time. These transactions may be effected in the over-the-counter market or otherwise.

In relation to each Member State of the European Economic Area which has implemented the Prospectus Directive (each, a Relevant Member State), each underwriter has represented and agreed that with effect from and including the date on which the Prospectus Directive is implemented in that Relevant Member State (the Relevant Implementation Date) it has not made and will not make an offer of notes to the public in that Relevant Member State prior to the publication of a prospectus in relation to the notes which has been approved by the competent authority in that Relevant Member State or, where appropriate, approved in another Relevant Member State and notified to the competent authority in that Relevant Member State, all in accordance with the Prospectus Directive, except that it may, with effect from and including the Relevant Implementation Date, make an offer of notes to the public in that Relevant Member State at any time:

(a) to legal entities which are authorised or regulated to operate in the financial markets or, if not so authorised or regulated, whose corporate purpose is solely to invest in securities;

(b) to any legal entity which has two or more of (1) an average of at least 250 employees during the last financial year; (2) a total balance sheet of more than €43,000,000 and (3) an annual net turnover of more than €50,000,000, as shown in its last annual or consolidated accounts; or

(c) in any other circumstances which do not require the publication by the Issuer of a prospectus pursuant to Article 3 of the Prospectus Directive.

For the purposes of this provision, the expression an “offer of notes to the public” in relation to any notes in any Relevant Member State means the communication in any form and by any means of sufficient information on the terms of the offer and the notes to be offered so as to enable an investor to decide to purchase or subscribe the notes, as the same may be varied in that Member State by any measure implementing the Prospectus Directive in that Member State and the expression Prospectus Directive means Directive 2003/71/EC and includes any relevant implementing measure in each Relevant Member State.

Each Underwriter has represented and agreed that:

(a) it has only communicated or caused to be communicated and will only communicate or cause to be communicated an invitation or inducement to engage in investment activity (within the meaning of section 21 of FSMA) to persons who have professional experience in matters relating to investments falling within Article 19(5) of the Financial Services and Markets Act 2000 (Financial Promotion) Order 2005 or in circumstances in which section 21 of FSMA does not apply to the company; and

(b) it has complied with, and will comply with, all applicable provisions of FSMA with respect to anything done by it in relation to the notes in, from or otherwise involving the United Kingdom.

The notes may not be offered or sold by means of any document other than (i) in circumstances which do not constitute an offer to the public within the meaning of the Companies Ordinance (Cap.32, Laws of Hong Kong), or (ii) to “professional investors” within the meaning of the Securities and Futures Ordinance (Cap.571, Laws of Hong Kong) and any rules made thereunder, or (iii) in other circumstances which do not result in the document being a “prospectus” within the meaning of the Companies Ordinance (Cap.32, Laws of Hong Kong), and no advertisement, invitation or document relating to the notes may be issued or may be in the possession of any person for the purpose of issue (in each case whether in Hong Kong or elsewhere), which is directed at, or

50

the contents of which are likely to be accessed or read by, the public in Hong Kong (except if permitted to do so under the laws of Hong Kong) other than with respect to notes which are or are intended to be disposed of only to persons outside Hong Kong or only to “professional investors” within the meaning of the Securities and Futures Ordinance (Cap. 571, Laws of Hong Kong) and any rules made thereunder.

The notes have not been and will not be registered under the Securities and Exchange Law of Japan (the Securities and Exchange Law) and each underwriter has agreed that it will not offer or sell any notes, directly or indirectly, in Japan or to, or for the benefit of, any resident of Japan (which term as used herein means any person resident in Japan, including any corporation or other entity organized under the laws of Japan), or to others for re-offering or resale, directly or indirectly, in Japan or to a resident of Japan, except pursuant to an exemption from the registration requirements of, and otherwise in compliance with, the Securities and Exchange Law and any other applicable laws, regulations and ministerial guidelines of Japan.

This prospectus has not been registered as a prospectus with the Monetary Authority of Singapore. Accordingly, this prospectus and any other document or material in connection with the offer or sale, or invitation for subscription or purchase, of the notes may not be circulated or distributed, nor may the notes be offered or sold, or be made the subject of an invitation for subscription or purchase, whether directly or indirectly, to persons in Singapore other than (i) to an institutional investor under Section 274 of the Securities and Futures Act, Chapter 289 of Singapore (the “SFA”), (ii) to a relevant person, or any person pursuant to Section 275(1A), and in accordance with the conditions, specified in Section 275 of the SFA or (iii) otherwise pursuant to, and in accordance with the conditions of, any other applicable provision of the SFA.

Where the notes are subscribed or purchased under Section 275 by a relevant person which is: (a) a corporation (which is not an accredited investor) the sole business of which is to hold investments and the entire share capital of which is owned by one or more individuals, each of whom is an accredited investor; or (b) a trust (where the trustee is not an accredited investor) whose sole purpose is to hold investments and each beneficiary is an accredited investor, shares, debentures and units of shares and debentures of that corporation or the beneficiaries’ rights and interest in that trust shall not be transferable for 6 months after that corporation or that trust has acquired the notes under Section 275 except: (1) to an institutional investor under Section 274 of the SFA or to a relevant person, or any person pursuant to Section 275(1A), and in accordance with the conditions, specified in Section 275 of the SFA; (2) where no consideration is given for the transfer; or (3) by operation of law.

We estimate that our share of the total expenses of the offering, excluding underwriting discounts and commissions, will be approximately $250,000. The underwriters have also agreed to reimburse us for up to $150,000 in expenses incurred by us in connection with this offering.

We have agreed to indemnify the several underwriters against certain liabilities, including liabilities under the Securities Act of 1933.

Item 15. Indemnification of Directors and Officers.

Section 1031 of the Oklahoma General Corporation Act, under which Chesapeake is incorporated, authorizes the indemnification of directors and officers under certain circumstances. Article VIII of the Certificate of Incorporation of Chesapeake and Article VI of the Bylaws of Chesapeake also provide for indemnification of directors and officers under certain circumstances. These provisions, together with Chesapeake’s indemnification obligations under individual indemnity agreements with its directors and officers, may be sufficiently broad to indemnify such persons for liabilities under the Securities Act of 1933 (the “Securities Act”), as amended. In addition, Chesapeake maintains insurance, which insures its directors and officers against certain liabilities.

The Oklahoma General Corporation Act provides for indemnification of each of Chesapeake’s officers and directors against (a) expenses, including attorneys’ fees, judgments, fines and amounts paid in settlement actually and reasonably incurred by them in connection with any action, suit or proceeding brought by reason of such person being or having been a director, officer, employee or agent of Chesapeake, or of any other corporation, partnership, joint venture, trust or other enterprise at the request of Chesapeake, other than an action by or in the right of Chesapeake. To be entitled to indemnification, the individual must have acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interest of Chesapeake, and with respect to any criminal action, the person seeking indemnification had no reasonable cause to believe that the conduct was unlawful and (b) expenses, including attorneys’ fees, actually and reasonably incurred in connection with the defense or settlement of any action or suit by or in the right of Chesapeake brought by reason of the person seeking indemnification being or having been a director, officer, employee or agent of Chesapeake, or any other corporation, partnership, joint venture, trust or other enterprise at the request of Chesapeake, provided the actions were in good faith and were reasonably believed to be in or not opposed to the best interest of Chesapeake, except that no indemnification shall be made in respect of any claim, issue or matter as to which the individual shall have been adjudged liable to Chesapeake, unless and only to the extent that the court in which such action was decided has determined that the person is fairly and reasonably entitled to indemnity for such expenses which the court deems proper. Article VIII of Chesapeake’s Certificate of Incorporation provides for indemnification of Chesapeake’s director and officers. The Oklahoma General Corporation Act also permits Chesapeake to purchase and maintain insurance on behalf of Chesapeake’s directors and officers against any liability arising out of their status as such, whether or not Chesapeake would have the power to indemnify them against such liability. These provisions may be sufficiently broad to indemnify such persons for liabilities arising under the Securities Act.

II-1

Chesapeake has entered into indemnity agreements with each of its directors and executive officers. Under each indemnity agreement, Chesapeake will pay on behalf of the indemnitee any amount which he is or becomes legally obligated to pay because of (a) any claim or claims from time to time threatened or made against him by any person because of any act or omission or neglect or breach of duty, including any actual or alleged error or misstatement or misleading statement, which he commits or suffers while acting in his capacity as a director and/or officer of Chesapeake or an affiliate or (b) being a party, or being threatened to be made a party, to any threatened, pending or contemplated action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that he is or was an officer, director, employee or agent of Chesapeake or an affiliate or is or was serving at the request of Chesapeake as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise. The payments which Chesapeake would be obligated to make under an indemnification agreement could include damages, charges, judgments, fines, penalties, settlements and costs, cost of investigation and cost of defense of legal, equitable or criminal actions, claims or proceedings and appeals therefrom, and costs of attachment, supersedeas, bail, surety or other bonds. Chesapeake also provides liability insurance for each of its directors and executive officers.

Item 17. Undertakings.

The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by section 10(a)(3) of the Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement;

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by registrants pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

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

(4) That, for purposes of determining any liability under the Securities Act of 1933, each filing of Registrant’s annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

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

II-3

(6) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(A) Each prospectus filed by a Registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(B) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5) or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which the prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(7) That, for the purpose of determining liability of a Registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, each undersigned Registrant undertakes that in a primary offering of securities of an undersigned Registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned Registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of an undersigned Registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of an undersigned Registrant or used or referred to by an undersigned Registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about an undersigned Registrant or its securities provided by or on behalf of an undersigned Registrant; and

(iv) Any other communication that is an offer in the offering made by an undersigned Registrant to the purchaser.

UNDERWRITING AGREEMENT

June [    ], 2006

BANC OF AMERICA SECURITIES LLC

As Representative (the “Representative”) of the Several Underwriters

c/o Banc of America Securities LLC

9 West 57^th Street, 40^th Floor

New York, NY 10019

Dear Sirs:

1. Introductory. Chesapeake Energy Corporation, an Oklahoma corporation (the “Company”), proposes to issue and sell to the several underwriters named in Schedule A hereto (the “Underwriters”) $[            ] principal amount of the Company’s [            ]% Senior Notes due 2013 (the “Offered Securities”). The Offered Securities will be unconditionally guaranteed (the “Guarantees”) on a senior basis by each existing domestic subsidiary other than Nomac 100 Corp. and certain de minimus subsidiaries of the Company and one of its foreign subsidiaries, and by subsequently acquired or designated Restricted Subsidiaries (as defined in the Indenture referred to below) of the Company in accordance with the terms of the Indenture (collectively, the “Subsidiary Guarantors”). The Offered Securities are to be issued under an indenture dated as of [            ], 2006 (the “Indenture”), among the Company and The Bank of New York Trust Company, N.A., as trustee (the “Trustee”). The Company hereby agrees with the Underwriters as follows:

2. Representations and Warranties of the Company. The Company and each Subsidiary Guarantor represents and warrants to, and agrees with, the several Underwriters that:

(a) A registration statement (No. 333-[•]), including all materials incorporated by reference therein and a prospectus, relating to the Offered Securities has been filed with the Securities and Exchange Commission (the “Commission”) and has become effective. Such registration statement, including all materials incorporated by reference therein and any prospectus or prospectus supplement deemed or retroactively deemed to be part thereof that has not been superceded or modified, is hereinafter referred to as the “Registration Statement”. “Registration Statement” without reference to a time means the Registration Statement as of the date and time of its filing and effectiveness which time shall be considered the “effective date” of the Registration Statement. For purposes of the previous sentence, information contained in a form of prospectus or prospectus supplement that is deemed retroactively to be a part of the Registration Statement pursuant to Rule 430B (“Rule 430B”) under the Securities Act of 1933 (the “Act”) shall be considered to be included in the Registration Statement as of the time

specified in Rule 430B. “Statutory Prospectus” as of any time means the prospectus included in the Registration Statement immediately prior to that time, including any document incorporated by reference therein and any basic prospectus or prospectus supplement deemed to be a part thereof that has not been superseded or modified. For purposes of the preceding sentence, information contained in a form of prospectus (including a prospectus supplement) that is deemed retroactively to be a part of the Registration Statement pursuant to Rule 430B shall be considered to be included in the Statutory Prospectus as of the actual time that form of prospectus (including a prospectus supplement) is filed with the Commission pursuant to Rule 424(b) (“Rule 424(b)”) under the Act. “Prospectus” means the Statutory Prospectus that discloses the public offering price and other final terms of the Offered Securities and otherwise satisfies Section 10(a) of the Act. “Issuer Free Writing Prospectus” means any “issuer free writing prospectus,” as defined in Rule 433, relating to the Offered Securities in the form filed or required to be filed with the Commission or, if not required to be filed, in the form retained in the Company’s records pursuant to Rule 433(g). “General Use Issuer Free Writing Prospectus” means any Issuer Free Writing Prospectus that is intended for general distribution to prospective investors, as evidenced by its being specified in Schedule B to this Agreement. “Limited Use Issuer Free Writing Prospectus” means any Issuer Free Writing Prospectus that is not a General Use Issuer Free Writing Prospectus. “Applicable Time” means :00 [a/p]m (Eastern time) on the date of this Agreement.

(b) On its effective date, the Registration Statement conformed in all respects to the requirements of the Act and the rules and regulations of the Commission (the “Rules and Regulations”) and did not include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, and on the date of this Agreement, the Registration Statement and the Prospectus will conform in all respects to the requirements of the Act and the Rules and Regulations, and neither of such documents will include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, except that the foregoing does not apply to statements in or omissions from any of such documents based upon written information furnished to the Company by any Underwriter through the Representative, if any, specifically for use therein, it being understood and agreed that the only such information furnished by an Underwriter consists of the information described as such in Section 8(b) hereof. The documents incorporated by reference in the Prospectus (the “Company Filed Documents”), when they became effective or were filed with the Commission, as the case may be, conformed in all material respects with the requirements of the Act or the Securities Exchange Act of 1934 (the “Exchange Act”), as applicable, and the Rules and Regulations.

(c) The Registration Statement is an “automatic shelf registration statement”, as defined in Rule 405 under the Act, that initially became effective within three years of the date of this Agreement, and as of the determination date applicable to the Registration Statement (and any amendment thereof) and the offering contemplated hereby, the Company is a “well-known seasoned issuer” (as defined in Rule 405 under the Act). If immediately prior to the third anniversary (the “Renewal Deadline”) of the initial effective date of the Registration Statement, any of the Offered Securities remain unsold by the Underwriters, the Company will prior to the Renewal Deadline file, if it has not already done so and is eligible to do so, a new automatic shelf registration statement relating to the Offered Securities, in a form satisfactory to the Representative. If the Company is no longer eligible to file an automatic shelf registration statement, the Company will prior to the Renewal Deadline, if it has not already done so, file a new shelf registration statement relating to the Offered Securities, in a form satisfactory to the Representative, and will use its best efforts to cause such registration statement to be declared effective within 180 days after the Renewal Deadline. The Company will take all other action necessary or appropriate to permit the public offering and sale of the Offered Securities to continue as contemplated in the expired registration statement relating to the Offered Securities. References herein to the Registration Statement shall include such new automatic shelf registration statement or such new shelf registration statement, as the case may be.

2

(d) The Company has not received from the Commission any notice pursuant to Rule 401(g)(2) objecting to use of the automatic shelf registration statement form. If at any time when Offered Securities remain unsold by the Underwriters the Company receives from the Commission a notice pursuant to Rule 401(g)(2) or otherwise ceases to be eligible to use the automatic shelf registration statement form, the Company will (i) promptly notify the Representative, (ii) promptly file a new registration statement or post-effective amendment on the proper form relating to the Offered Securities, in a form satisfactory to the Representative, (iii) use its best efforts to cause such registration statement or post-effective amendment to be declared effective as soon as practicable, and (iv) promptly notify the Representative of such effectiveness. The Company will take all other action necessary or appropriate to permit the public offering and sale of the Offered Securities to continue as contemplated in the registration statement that was the subject of the Rule 401(g)(2) notice or for which the Company has otherwise become ineligible. References herein to the registration statement relating to the Offered Securities shall include such new registration statement or post-effective amendment, as the case may be.

(e) The Company has paid or shall pay the required Commission filing fees relating to the Offered Securities within the time required by Rule 456(b)(1) without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r).

(h) Each Issuer Free Writing Prospectus, as of its issue date and at all subsequent times through the completion of the public offer and sale of the Offered Securities or until any earlier date that the Company notified or notifies the Representative as described in the next sentence, did not, does not and will not include any information that conflicted, conflicts or will conflict with the information then contained in the Registration Statement. If at any time following issuance of an Issuer Free Writing Prospectus there occurred or occurs an event or development as a result of which such Issuer Free Writing Prospectus conflicted or would conflict with the information then contained in the Registration Statement or included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at that subsequent time, not misleading, (i) the Company has promptly notified or will promptly notify the Representative and (ii) the Company has promptly amended or will promptly amend or supplement such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission.

On the basis of the representations, warranties and agreements herein contained, but subject to the terms and conditions herein set forth, the Company agrees to sell to the Underwriters, and the Underwriters agree, severally and not jointly, to purchase from the Company, at a purchase price of [            ]% of the principal amount thereof plus accrued interest from June [            ], 2006 to the Closing Date, the respective principal amounts of Offered Securities set forth opposite the names of the Underwriters in Schedule A hereto.

The Prospectus shall be so furnished on or prior to 3:00 p.m., New York time, on the business day following the execution and delivery of this Agreement. All other documents shall be so furnished as soon as available. The Company will pay the expenses of printing and distributing to the Underwriters all such documents.

6. Free Writing Prospectuses. (a) The Company represents and agrees that (other than the final term sheet prepared and filed pursuant to Section 5(a) hereto), unless it obtains the prior consent of the Representative, and each Underwriter represents and agrees that (other than one or more term sheets relating to the Offered Securities containing customary information and conveyed to purchasers of Offered Securities), unless it obtains the prior consent of the Company and the Representative, it has not made and will not make any offer relating to the Offered Securities that would constitute an Issuer Free Writing Prospectus, or that would otherwise constitute a “free writing prospectus,” as defined in Rule 405, required to be filed with the Commission. Any such free writing prospectus consented to by the Company and the Representative is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company represents that it has treated and agrees that it will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433, and has complied and will comply with the requirements of Rule 433 applicable to any Permitted Free Writing Prospectus, including timely Commission filing where required, legending and record keeping.

(ix) The Registration Statement has become effective under the Act, the Prospectus was filed with the Commission pursuant to the subparagraph of Rule 424(b) specified in such opinion on the date specified therein in the manner and within the time period required by Rule 424 and in compliance with Rule 430B, and, to the best of the knowledge of such counsel, no stop order suspending the effectiveness of the Registration Statement or any part thereof has been issued and no proceedings for that purpose have been instituted or are pending or contemplated under the Act, and the Registration Statement, as of its effective date and as of the date of this Agreement and the Prospectus as of the Applicable Time, and any amendment or supplement thereto, as of its date, complied as to form in all material respects with the requirements of the Act and the Rules and Regulations; each of the documents incorporated by reference in the Registration Statement, at the time it became effective or was filed with the Commission (or the time of filing of an amendment, if so amended), as the case may be, complied as to form in all material respects with the requirements of the Act or Exchange Act, as the case may be, and the Rules and Regulations; the descriptions in the Registration Statement and the Prospectus of statutes, legal and governmental proceedings and contracts and other documents are accurate and fairly present the information required to be shown; and such counsel do not know of any legal or governmental proceedings required to be described in the Prospectus which are not described as required or of any contracts or documents of a character required to be described in the Registration Statement or Prospectus or to be filed as exhibits to the Registration Statement which are not described and filed as required.

11

It is understood and agreed that certain of the opinions set forth in paragraphs (i), (ii), (iii), (v) (with respect to conflicts with charters, by-laws or similar organizational documents and with respect to certain of the documents filed as exhibits to the filings described in such paragraph) and (viii) (with respect to due authorization) may be given by the Commercial Law Group, P.C., and certain opinions in paragraphs (vii) and (ix) may be given by Henry Hood, Esq.

In addition, Vinson & Elkins L.L.P. shall state that they have participated in conferences with officers and other representatives of the Company, representatives of the independent public accountants of the Company, general counsel of the Company, representatives of the Underwriters and counsel for the Underwriters, at which conferences the Registration Statement and the Prospectus were discussed. Such counsel shall further state that, although they have made certain additional inquiries and investigations in connection with the preparation of the Registration Statement and the Prospectus, they have not verified, are not passing on and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement or the Prospectus or any documents incorporated by reference therein, based on the participation described above in the course of acting as counsel to the Company in this transaction, no information has come to their attention that has caused such counsel to believe that the Registration Statement, at the time it became effective, or the Prospectus, at the date hereof and as of the Closing Date (other than the financial statements and schedules and other financial data and the oil and gas reserve data, in each case contained or incorporated by reference (including the notes thereto and auditor’s report thereon) therein, as to which such counsel need not express any comment or belief) contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading; such counsel shall also state that they have no reason to believe that the documents specified in a schedule to such counsel’s letter, consisting of those included in the General Disclosure Package, as of the Applicable Time and as of the Closing Date, contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

(e) The Representative shall have received from Cravath, Swaine & Moore LLP, counsel for the Underwriters, such opinion or opinions, dated the Closing Date, with respect to the incorporation of the Company, the validity of the Offered Securities delivered on the Closing Date, the Registration Statement, the Prospectus and other related matters as the Representative may require, and the Company shall have furnished to such counsel such documents as they request for the purpose of enabling them to pass upon such matters. In rendering such opinion, Cravath, Swaine & Moore LLP may rely as to the incorporation of the Company and all other matters governed by Oklahoma law upon the opinion of Commercial Law Group, P.C. referred to above.

(f) The Representative shall have received a certificate, dated the Closing Date, of the President or any Vice President and a principal financial or accounting officer of the Company in which such officers, on behalf of the Company, shall state that the representations and warranties of the Company in this Agreement are true and correct, that the Company has complied with all agreements and satisfied all conditions on its part to be performed or satisfied hereunder at or prior to the Closing Date, that no stop order suspending the effectiveness of the Registration Statement or of any part thereof has been issued and no proceedings for that purpose have been instituted or are contemplated by the Commission and that, subsequent to the date of the most recent financial statements included or incorporated by reference into the Registration Statement and the General Disclosure Package, there has been no material adverse change, nor any development or event involving a prospective material adverse change, in the condition (financial or other), business, properties or results of operations of the Company and its subsidiaries taken as a whole except as set forth in or contemplated by the Registration Statement and the General Disclosure Package or as described in such certificate.

(g) The Representative shall have received a letter (the “Bring-Down Comfort Letter”), dated the Closing Date, of PricewaterhouseCoopers LLP (i) confirming that they are independent public accountants with respect to the Company and its subsidiaries within the meaning of the Act and the applicable Rules and Regulations thereunder, (ii) stating, as of the date

12

of the Bring-Down Comfort Letter (or, with respect to matters involving changes or developments since the respective dates as of which specified financial information is given in the Registration Statement and the General Disclosure Package, as of a date not more than three business days prior to the date of the Bring-Down Comfort Letter), that the conclusions and findings of such accountants with respect to the financial information and other matters covered by the Initial Comfort Letter are accurate, (iii) confirming in all material respects the conclusions and findings set forth in the Initial Comfort Letter and (iv) otherwise in form and substance satisfactory in all respects to the Representative and PricewaterhouseCoopers LLP.

(h) The Representative shall have received (i) a copy of the certificate or articles of incorporation, including all amendments thereto, of the Company, certified as of a recent date by the Secretary of State of the State of Oklahoma, (ii) a certificate of good standing for the Company, dated as of a recent date, from such Secretary of State and (iii) a certificate, dated as of a recent date, of the Secretary of State of each state in which the Company is qualified to do business as a foreign corporation under the laws of such state.

(j) The Representative shall have received a letter dated on or prior to the Closing Date, of Ernst & Young LLP in form and substance satisfactory to the Representative and Ernst & Young LLP.

The Company will furnish the Representative with such conformed copies of such opinions, certificates, letters and documents as the Representative reasonably requests. The Representative may in its sole discretion waive on behalf of the Underwriters compliance with any conditions to the obligations of the Underwriters hereunder.

8. Indemnification and Contribution. (a) The Company will indemnify and hold harmless each Underwriter, its partners, directors and officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Act, against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act or the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, each Statutory Prospectus, the Prospectus, any Issuer Free Writing Prospectus or any amendment or supplement thereto, any related preliminary prospectus or preliminary prospectus supplement, or any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Act or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representative specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in subsection (b) below.

(b) Each Underwriter will severally and not jointly indemnify and hold harmless the Company, its directors and officers and each person, if any, who controls the Company within the meaning of Section 15

13

of the Act, against any losses, claims, damages or liabilities to which the Company may become subject, under the Act or the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, each Statutory Prospectus, the Prospectus, any Issuer Free Writing Prospectus or any amendment or supplement thereto, or any related preliminary prospectus or preliminary prospectus supplement, or arise out of or are based upon the omission or the alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representative specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred, it being understood and agreed that the only such information furnished by any Underwriter consists of the following information in the Prospectus furnished on behalf of each Underwriter: (i) the concession and reallowance figures appearing in the second paragraph under the caption “Underwriting” and (ii) paragraph [•] under the caption “Underwriting”.

(c) Promptly after receipt by an indemnified party under this Section of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under subsection (a) or (b) above, notify the indemnifying party in writing of the commencement thereof; but the failure to notify the indemnifying party will not relieve it from any liability which it may have under subsection (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to any indemnified party otherwise than under subsection (a) or (b) above. In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, if such indemnified party shall have been advised by counsel that there are one or more defenses available to it that are in conflict with those available to the indemnifying party (in which case the indemnifying party shall not have the right to direct the defense of such action on behalf of the indemnified party), the reasonable fees and expenses of such indemnified party’s counsel shall be borne by the indemnifying party. In no event shall the indemnifying party be liable for the fees and expenses of more than one counsel (together with appropriate local counsel) at any time for any indemnified party in connection with any one action or separate but substantially similar or related actions arising in the same jurisdiction out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and does not include a statement as to or an admission of fault, culpability or failure to act by or on behalf of any indemnified party.

(d) If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the Offered Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses,

14

claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters from the Company under this Agreement. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Offered Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this subsection (d) to contribute are several in proportion to their respective underwriting obligations and not joint.

(e) The obligations of the Company under this Section shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of the Act or the Exchange Act; and the obligations of the Underwriters under this Section shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each director of the Company, to each officer of the Company who has signed the Registration Statement and to each person, if any, who controls the Company within the meaning of the Act or the Exchange Act.

9. Default of Underwriters. If any Underwriter or Underwriters default in their obligations to purchase Offered Securities hereunder the aggregate principal amount of Offered Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total principal amount of Offered Securities, the Representative may make arrangements satisfactory to the Company for the purchase of such Offered Securities by other persons, including any of the Underwriters, but if no such arrangements are made by the Closing Date, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Offered Securities that such defaulting Underwriters agreed but failed to purchase. If any Underwriter or Underwriters so default and the aggregate principal amount of Offered Securities with respect to which such default or defaults occur exceeds 10% of the total principal amount of Offered Securities and arrangements satisfactory to the Representative and the Company for the purchase of such Offered Securities by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter or the Company, except as provided in Section 10. As used in this Agreement, the term “Underwriter” includes any person substituted for an Underwriter under this Section. Nothing herein will relieve a defaulting Underwriter from liability for its default.

10. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Company or its officers and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the Company or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Offered Securities. If this Agreement is terminated pursuant to Section 9 or if for any reason the purchase of the Offered Securities by the Underwriters is not consummated, the Company shall remain responsible for the expenses to be paid or reimbursed by it pursuant to Section 5 and the respective obligations of the Company and the Underwriters pursuant to Section 8 shall remain in effect, and if any Offered Securities have been

15

purchased hereunder the representations and warranties in Section 2 and all obligations under Section 5 shall also remain in effect. If the purchase of the Offered Securities by the Underwriters is not consummated for any reason other than solely because of the termination of this Agreement pursuant to Section 9 or the occurrence of any event specified in clause (iii), (iv) (other than any suspension of trading of any securities of the Company on any exchange or in the over-the-counter market), (v), (vi) or (vii) of Section 7(c), the Company will reimburse the Underwriters for all out-of-pocket expenses (including fees and disbursements of counsel) reasonably incurred by them in connection with the offering of the Offered Securities.

11. Research Independence. In addition, the Company acknowledges that the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Underwriters’ research analysts may hold and make statements or investment recommendations and/or publish research reports with respect to the Company and/or the offering that differ from the views of its investment bankers. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Company by such Underwriters’ investment banking divisions. The Company acknowledges that each of the Underwriters is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the companies which may be the subject of the transactions contemplated by this Agreement.

12. No Fiduciary Duty. The Company acknowledges and agrees that in connection with this offering, the sale of the Offered Securities or any other services the Underwriters may be deemed to be providing hereunder, notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Underwriters: (i) no fiduciary or agency relationship between the Company and any other person, on the one hand, and the Underwriters, on the other, exists; (ii) the Underwriters are not acting as advisors, expert or otherwise, to the Company, including, without limitation, with respect to the determination of the public offering price of the Offered Securities, and such relationship between the Company, on the one hand, and the Underwriters, on the other, is entirely and solely commercial, based on arms-length negotiations; (iii) any duties and obligations that the Underwriters may have to the Company shall be limited to those duties and obligations specifically stated herein; and (iv) the Underwriters and their respective affiliates may have interests that differ from those of the Company. The Company hereby waives any claims that the Company may have against the Underwriters with respect to any breach of fiduciary duty in connection with the offering.

13. Notices. All communications hereunder will be in writing and, if sent to the Underwriters, will be mailed, delivered or telegraphed and confirmed to the Underwriters, c/o Banc of America Securities LLC, 9 West 57^th Street, 40^th Floor, New York, NY 10019, Attention: [            ] or, if sent to the Company, will be mailed, delivered or telegraphed and confirmed to it at Chesapeake Energy Corporation, 6100 North Western Avenue, Oklahoma City, Oklahoma 73118, Attention: Corporate Secretary; provided, however, that any notice to an Underwriter pursuant to Section 8 will be mailed, delivered or telegraphed and confirmed to such Underwriter.

14. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and controlling persons referred to in Section 7, and no other person will have any right or obligation hereunder.

15. Representation of Underwriters. The Representative will act for the several Underwriters in connection with this financing, and any action under this Agreement taken by the Representative will be binding upon all the Underwriters.

16

16. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same Agreement.

17. Applicable Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York without regard to principles of conflicts of laws. The Company hereby submits to the non-exclusive jurisdiction of the Federal and state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

Each of the Underwriters and the Company (on its behalf and, to the extent permitted by applicable law, on behalf of its stockholders and affiliates) waives all right to trial by jury in any action, proceeding or counterclaim (whether based upon contract, tort or otherwise) in any way arising out of or relating to this Agreement.

17

If the foregoing is in accordance with the Representative’s understanding of our agreement, kindly sign and return to us one of the counterparts hereof, whereupon it will become a binding agreement between the Company and several Underwriters in accordance with its terms.

THE SECURITIES

SECTION 2.01. Form and Dating. Provisions relating to the Securities are set forth in the Appendix attached hereto (the “Appendix”) which is hereby incorporated in and expressly made part of this Indenture. The Securities and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit 1 to the Appendix which is hereby incorporated in and expressly made a part of this Indenture. The Securities may have notations, legends or endorsements required by law, stock exchange rule, agreements to which

14

the Company is subject, if any, or usage (provided that any such notation, legend or endorsement is in a form acceptable to the Company and to the Trustee). Each Security shall be dated the date of its authentication. The terms of the Securities set forth in the Appendix and Exhibit 1 are part of the terms of this Indenture.

SECTION 2.02. Execution and Authentication. Two Officers shall sign the Securities for the Company by manual or facsimile signature.

If an Officer whose signature is on a Security no longer holds that office at the time the Trustee authenticates the Security, the Security shall be valid nevertheless.

A Security shall not be valid until an authorized signatory of the Trustee manually signs the certificate of authentication on the Security. The signature shall be conclusive evidence that the Security has been authenticated under this Indenture.

On the Issue Date, the Trustee shall authenticate and deliver $[            ] million of Securities and, at any time and from time to time thereafter, the Trustee shall authenticate and deliver Securities for original issue in an aggregate principal amount specified in such order, in each case upon a written order of the Company signed by two Officers or by an Officer and either an Assistant Treasurer or an Assistant Secretary of the Company. Such order shall specify the amount of the Securities to be authenticated and the date on which the original issue of Securities is to be authenticated.

The Trustee may appoint an authenticating agent reasonably acceptable to the Company to authenticate the Securities. Unless limited by the terms of such appointment, an authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights with respect to the Company as any Registrar, Paying Agent or agent for service of notices and demands.

SECTION 2.03. Registrar and Paying Agent. The Company shall maintain an office or agency where Securities may be presented for registration of transfer or for exchange (the “Registrar”) and an office or agency where Securities may be presented for payment (the “Paying Agent”). The Registrar shall keep a register of the Securities and of their transfer and exchange. The Company may have one or more co-registrars and one or more additional paying agents. The term “Paying Agent” includes any additional paying agent.

The Company shall enter into an appropriate agency agreement with any Registrar, Paying Agent or co-registrar not a party to this Indenture, which shall incorporate the terms of the TIA. The agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee of the name and address of any such agent and shall furnish the Trustee with an executed counterpart of any such agency agreement. If the Company fails to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefor pursuant to Section 7.07. The Company or any wholly owned Subsidiary

15

incorporated or organized within The United States of America may act as Paying Agent, Registrar, co-registrar or transfer agent.

The Company initially appoints the Trustee as Registrar and Paying Agent in connection with the Securities.

SECTION 2.04. Paying Agent To Hold Money in Trust. Prior to 11:00 a.m., New York time, each due date of the principal and interest on any Security, the Company shall deposit with the Paying Agent a sum sufficient to pay such principal and interest when so becoming due. The Company shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal of or interest on the Securities and shall notify the Trustee of any default by the Company in making any such payment. If the Company or a Subsidiary acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed by the Paying Agent. Upon complying with this Section, the Paying Agent shall have no further liability for the money delivered to the Trustee.

SECTION 2.05. Holder Lists. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders. If the Trustee is not the Registrar, the Company shall furnish to the Trustee, in writing at least five Business Days before each interest payment date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders.

SECTION 2.06. Transfer and Exchange. The Securities shall be issued in registered form and shall be transferable only upon the surrender of a Security for registration of transfer. When a Security is presented to the Registrar or a co-registrar with a request to register a transfer, the Registrar shall register the transfer as requested if the requirements of this Indenture and Section 8-401(a) of the Uniform Commercial Code are met. When Securities are presented to the Registrar or a co-registrar with a request to exchange them for an equal principal amount of Securities of other denominations, the Registrar shall make the exchange as requested if the same requirements are met.

SECTION 2.07. Replacement Securities. If a mutilated Security is surrendered to the Registrar or if the Holder of a Security claims that the Security has been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate a replacement Security if the requirements of Section 8-405 of the Uniform Commercial Code are met and the Holder satisfies any other reasonable requirements of the Trustee. If required by the Trustee or the Company, such Holder shall furnish an indemnity bond sufficient in the judgment of the Company and the Trustee to protect the Company, the Trustee, the Paying Agent, the Registrar and any co-registrar from any loss which any of them may suffer if a Security is replaced. The Company and the Trustee may charge the Holder for their expenses in replacing a Security.

16

Every replacement Security is an additional obligation of the Company.

SECTION 2.08. Outstanding Securities. Securities outstanding at any time are all Securities authenticated by the Trustee except for those canceled by it, those delivered to it for cancelation and those described in this Section as not outstanding. A Security does not cease to be outstanding because the Company or an Affiliate of the Company holds the Security.

If a Security is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee and the Company receive proof satisfactory to them that the replaced Security is held by a bona fide purchaser.

If the Paying Agent segregates and holds in trust, in accordance with this Indenture, on a redemption date or maturity date money sufficient to pay all principal and interest payable on that date with respect to the Securities (or portions thereof) to be redeemed or maturing, as the case may be, then on and after that date such Securities (or portions thereof) cease to be outstanding and interest on them ceases to accrue.

SECTION 2.09. Temporary Securities. Until definitive Securities are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Securities. Temporary Securities shall be substantially in the form of definitive Securities but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate definitive Securities and deliver them in exchange for temporary Securities.

SECTION 2.10. Cancelation. The Company at any time may deliver Securities to the Trustee for cancelation. The Registrar and the Paying Agent shall forward to the Trustee any Securities surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else shall cancel and dispose of (subject to the record retention requirements of the Exchange Act) all Securities surrendered for registration of transfer, exchange, payment or cancelation in its customary manner and upon request shall deliver a certificate of such disposal to the Company unless the Company directs the Trustee to deliver canceled Securities to the Company. The Company may not issue new Securities to replace Securities it has redeemed, paid or delivered to the Trustee for cancelation.

SECTION 2.11. Defaulted Interest. If the Company defaults in a payment of interest on the Securities, the Company shall pay defaulted interest (plus interest on such defaulted interest to the extent lawful) in any lawful manner. The Company may pay the defaulted interest to the persons who are Holders on a subsequent special record date. The Company shall fix or cause to be fixed any such special record date and payment date to the reasonable satisfaction of the Trustee and shall promptly mail to each Holder a notice that states the special record date, the payment date and the amount of defaulted interest to be paid.

17

SECTION 2.12. CUSIP Numbers. The Company in issuing the Securities may use “CUSIP” numbers (if then generally in use) and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company shall notify the Trustee of any change in the CUSIP numbers.

SECTION 2.13. Issuance of Additional Securities. The Company shall be entitled to issue Additional Securities under this Indenture which shall have identical terms as the Securities issued on the Issue Date, other than with respect to the date of issuance and issue price. The Securities issued on the Issue Date and any Additional Securities shall be treated as a single class for all purposes under this Indenture.

With respect to any Additional Securities, the Company shall set forth in a resolution of the Board of Directors and an Officers’ Certificate, a copy of each which shall be delivered to the Trustee, the following information:

(1) the aggregate principal amount of such Additional Securities to be authenticated and delivered pursuant to this Indenture; and

(2) the issue price, the issue date and the CUSIP number of such Additional Securities; provided, however, that no Additional Securities may be issued at a price that would cause such Additional Securities to have “original issue discount” within the meaning of Section 1273 of the Code.

Additional Securities may be issued with the same CUSIP number as the Securities issued on the Issue Date if, and only if, the Company shall have provided the Trustee with an opinion of nationally recognized counsel, reasonably satisfactory to the Trustee, to the effect that such Additional Securities will be fungible with the Securities issued on the Issue Date for all United States federal income tax purposes.

ARTICLE THREE

REDEMPTION

SECTION 3.01. Notice to Trustee. If the Company elects to redeem Securities pursuant to the make-whole redemption provisions of Paragraph 5 of the Securities, it shall furnish to the Trustee and the Registrar, at least 45 days but not more than 60 days before the redemption date (unless the Trustee consents to a shorter period in writing), an Officers’ Certificate setting forth the redemption date, the principal amount of Securities to be redeemed and the redemption price, including the detail of the calculation of the Make-Whole Price.

18

SECTION 3.02. Selection of Securities to Be Redeemed. If less than all of the Securities are to be redeemed at any time, the Trustee shall select the Securities to be redeemed pro rata, by lot or, if the Securities are listed on any securities exchange, by any other method that the Trustee considers fair and appropriate and that complies with the requirements of such exchange; provided, however, that no Securities with a principal amount of $1,000 or less will be redeemed in part. The Trustee shall make the selection from outstanding Securities not previously called for redemption not less than 30 nor more than 60 days prior to the redemption date. Securities and portions of them it selects shall be in amounts of $1,000 or whole multiples of $1,000. Provisions of this Indenture that apply to Securities called for redemption also apply to portions of Securities called for redemption. The Trustee shall notify the Company promptly of the Securities or portions of Securities selected for redemption.

SECTION 3.03. Notice of Redemption. (a) At least 30 days but not more than 60 days before a redemption date, the Company shall mail a notice of redemption by first-class mail to each Holder of Securities to be redeemed at such Holder’s registered address.

The notice shall identify the Securities to be redeemed and shall state:

(1) the redemption date;

(2) the redemption price;

(3) the aggregate principal amount of Securities being redeemed;

(4) the name and address of the Paying Agent;

(5) that Securities called for redemption must be surrendered to the Paying Agent at the address specified in such notice to collect the redemption price;

(6) that, unless the Company defaults in the payment of the redemption price or accrued interest, interest on Securities called for redemption ceases to accrue on and after the redemption date and the only remaining right of the Holders is to receive payment of the redemption prices in respect of the Securities upon surrender to the Paying Agent of the Securities;

(7) if any Security is being redeemed in part, the portion of the principal amount of such Security to be redeemed and that, after the redemption date, upon surrender of such Security, a new Security or Securities in principal amount equal to the unredeemed portion will be issued in the name of the Holder thereof upon cancelation of the Security or Securities being redeemed; and

(8) the CUSIP number of the Securities.

19

(b) At the Company’s request, the Trustee shall give the notice of redemption required in Section 3.03(a) in the Company’s name and at the Company’s expense; provided, however, that the Company shall deliver to the Trustee, at least 45 days prior to the redemption date (unless the Trustee consents to a shorter notice period in writing), an Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in Section 3.03(a).

SECTION 3.04. Effect of Notice of Redemption. Once notice of redemption is mailed in accordance with Section 3.03, Securities called for redemption become due and payable on the redemption date at the redemption price. Upon surrender to the Paying Agent, such Securities shall be paid at the redemption price, plus accrued and unpaid interest to the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the related interest payment date). Failure to give notice or any defect in the notice to any Holder shall not affect the validity of the notice to any other Holder.

SECTION 3.05. Deposit of Redemption Price. Prior to 11:00 a.m., New York time, on the redemption date, the Company shall deposit with the Paying Agent (or if the Company or a Subsidiary is the Paying Agent, shall segregate and hold in trust) funds available on the redemption date sufficient to pay the redemption price of, and accrued and unpaid interest on, the Securities to be redeemed on that date. The Paying Agent shall promptly return to the Company any money so deposited which is not required for that purpose upon the written request of the Company, except with respect to monies owed as obligations to the Trustee pursuant to Article Seven.

If any Security called for redemption shall not be so paid upon redemption because of the failure of the Company to comply with the preceding paragraph, interest will continue to be payable on the unpaid principal and premium, if any, including from the redemption date until such principal and premium, if any, is paid, and, to the extent lawful, on any interest not paid on such unpaid principal, in each case at the rate provided in the Securities and in Section 4.01 hereof.

SECTION 3.06. Securities Redeemed in Part. Upon surrender of a Security that is to be redeemed in part, the Company shall issue and the Trustee shall authenticate for the Holder, at the expense of the Company, a new Security equal in aggregate amount to the unredeemed portion of the Security surrendered.

SECTION 3.07. Optional Redemption at Make-Whole Price. At any time prior to the Maturity Date, the Company may, at its option, redeem all or any portion of the Securities at the Make-Whole Price plus accrued and unpaid interest on the Securities so redeemed to the date of redemption.

Any redemption pursuant to this Section 3.07 shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof.

The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

SECTION 4.05. Corporate Existence. The Company will do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence and the corporate, partnership or other existence of each Subsidiary and all rights (charter and statutory) and franchises of the Company and the Subsidiaries; provided, that the Company shall not be required to preserve the corporate existence of any Subsidiary, or any such right or franchise, if the Company shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and that the loss thereof is not disadvantageous in any material respect to the Holders.

SECTION 4.06. Waiver of Stay, Extension or Usury Laws. The Company and each Subsidiary Guarantor covenants (to the extent that each may lawfully do so) that it will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension, or usury law or other law, which would prohibit or forgive the Company or any Subsidiary Guarantor from paying all or any portion of the principal of, premium, if any, or interest on the Securities as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Indenture; and (to the extent that it may lawfully do so) each of the Company and the Subsidiary Guarantors hereby expressly waives all benefit or advantage of any such law, and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

The Company shall pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (a) all taxes, assessments and governmental charges levied or imposed upon the Company or any Subsidiary or upon the income, profits or property of the Company or any Subsidiary and (b) all lawful claims for labor, materials and supplies which, if unpaid, might by law become a Lien upon the property of the Company or any Subsidiary; provided, however, that the Company shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith by appropriate proceedings.

SECTION 4.08. Maintenance of Properties and Insurance. (a) The Company shall cause all properties used or held for use in the conduct of its business or the business of any Subsidiary to be maintained and kept in good condition, repair and working order (ordinary wear and

(b) The Company shall provide or cause to be provided, for itself and each of its Subsidiaries, insurance (including appropriate self-insurance) against loss or damage of the kinds that, in the reasonable, good faith opinion of the Company, are adequate and appropriate for the conduct of the business of the Company and such Subsidiaries in a prudent manner, with reputable insurers or with the government of the United States or an agency or instrumentality thereof, in such amounts, with such deductibles, and by such methods as shall be customary, in the reasonable, good faith opinion of the Company, for corporations similarly situated in the industry.

SECTION 4.09. Limitation on Liens Securing Indebtedness. The Company will not, and will not permit any Subsidiary to, create, incur or assume any Indebtedness secured by any Liens (other than Permitted Liens) upon any of the properties of the Company or any Subsidiary, unless the Securities or a Guarantee are equally and ratably secured; provided, that if such Indebtedness is expressly subordinated to the Securities or a Guarantee, the Lien securing such Indebtedness will be subordinated and junior to the Lien securing the Securities or such Guarantee.

SECTION 4.10. Limitation on Sale/Leaseback Transactions. (a) The Company will not, and will not permit any of its Subsidiaries to, enter into any Sale/Leaseback Transaction with any Person (other than the Company or any other Subsidiary) unless (i) the Company or such Subsidiary, as the case may be, would be entitled to incur secured Indebtedness in a principal amount equal to the Attributable Indebtedness with respect to such Sale/Leaseback Transaction in accordance with Section 4.09 or (ii) the Company or such Subsidiary receives proceeds from such Sale/Leaseback Transaction at least equal to the fair market value thereof (as determined in good faith by the Company’s Board of Directors, whose determination in good faith, evidenced by a resolution of such Board shall be conclusive) and such proceeds are applied in accordance with paragraphs (b) to (g) hereof.

(b) The Company may apply Net Available Proceeds from such Sale/Leaseback Transaction, within 365 days after receipt of Net Available Proceeds from the Sale/Leaseback Transaction, to: (i) the repayment of Indebtedness of the Company or a Subsidiary under Credit Facilities or other Senior Indebtedness, including any mandatory redemption or repurchase or make-whole redemption of the Existing Notes or the Securities; (ii) make an Investment in assets used in the Oil and Gas Business; or (iii) develop by drilling the Company’s oil and gas reserves.

24

(c) If, upon completion of the 365-day period referred to above, any portion of the Net Available Proceeds shall not have been applied by the Company as described in clauses (i), (ii) or (iii) of the immediately preceding paragraph and such remaining Net Available Proceeds, together with any remaining net cash proceeds from any prior Sale/Leaseback Transaction (such aggregate constituting “Excess Proceeds”), exceed $40,000,000, then the Company will be obligated to make an offer (the “Net Proceeds Offer”) to purchase the Securities and any other Senior Indebtedness in respect of which such an offer to purchase is required to be made concurrently with the Net Proceeds Offer having an aggregate principal amount equal to the Excess Proceeds (such purchase to be made on a pro rata basis if the amount available for such repurchase is less than the principal amount of the Securities and other Senior Indebtedness tendered in such Net Proceeds Offer) at a purchase price of 100% of the principal amount thereof plus accrued and unpaid interest on the Securities and other Senior Indebtedness so repurchased to the date of repurchase. Upon the completion of the Net Proceeds Offer, the amount of Excess Proceeds will be reset to zero.

(d) Within 15 days after the Company becomes obligated to make a Net Proceeds Offer (a “Net Proceeds Offer Triggering Event”), the Company (with notice to the Trustee and the Paying Agent), or the Trustee at the Company’s request and expense, will mail or cause to be mailed to all Holders on the date of the Net Proceeds Offer Triggering Event a notice prepared by the Company (the “Offer Notice”) of the occurrence of such Net Proceeds Offer Triggering Event and of the Holders’ rights arising as a result thereof. The Offer Notice will contain all instructions and materials necessary to enable Holders to tender their Securities to the Company. The Offer Notice, which shall govern the terms of the Net Proceeds Offer, shall state: (1) that the Net Proceeds Offer is being made pursuant to this Section 4.10; (2) the purchase price and the Net Proceeds Payment Date; (3) that any Security not tendered will continue to accrue interest at the stated rate; (4) that any Security accepted for payment pursuant to the Net Proceeds Offer shall cease to accrue interest on the Net Proceeds Payment Date; (5) that Holders electing to have a Security purchased pursuant to any Net Proceeds Offer will be required to surrender the Security, with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Security completed, to the Company, a depositary, if appointed by the Company, or a Paying Agent at the address specified in the notice prior to termination of the Net Proceeds Offer; (6) that Holders will be entitled to withdraw their election if the Company, depositary or Paying Agent, as the case may be, receives, not later than the expiration of the Net Proceeds Offer, or such longer period as may be required by law, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Security the Holder delivered for purchase and a statement that such Holder is withdrawing its election to have the Security purchased; and (7) that Holders whose Securities are purchased only in part will be issued Securities equal in principal amount to the unpurchased portion of the Securities surrendered. The Net Proceeds Offer shall be deemed to have commenced upon the mailing of the Offer Notice and shall terminate 20 Business Days after its commencement, unless a longer offering period is required by law.

(e) Promptly after the termination of the Net Proceeds Offer (“the Net Proceeds Payment Date”), the Company shall, to the

25

extent permitted by applicable law, (i) accept for payment Securities or portions thereof tendered pursuant to the Offer Notice, (ii) if the Company appoints a depositary or Paying Agent, deposit with such depositary or Paying Agent money sufficient to pay the purchase price of all Securities or portions thereof so tendered and (iii) deliver to the Trustee Securities so accepted together with an Officers’ Certificate stating the Securities or portions thereof tendered to the Company. The depositary, the Company or the Paying Agent, as the case may be, shall promptly mail to the Holders of Securities so accepted payment in an amount equal to the purchase price (representing those funds received pursuant to clause (ii) of this Section 4.10(c)), and the Trustee shall promptly authenticate and mail to each such Holder a new Security equal in principal amount to any unpurchased portion of the Security surrendered; provided that each such new Security will be in a principal amount of $1,000 or an integral multiple thereof. The Company will publicly announce the results of the Net Proceeds Offer on or as soon as practicable after the Net Proceeds Payment Date. For purposes of this Section 4.10, the Trustee shall act as the Paying Agent.

(f) The Company will comply with Section 14 of the Exchange Act and the provisions of Regulation 14E and any other tender offer rules under the Exchange Act and any other federal and state securities laws, rules and regulations which may then be applicable to any Net Proceeds Offer.

(g) During the period between any Sale/Leaseback Transaction and the application of the Net Available Proceeds therefrom in accordance with this covenant, all Net Available Proceeds shall be maintained in a segregated account and shall be invested in Permitted Financial Investments.

27

in the aggregate, or (B) such default results from the failure to pay when due principal of, premium, if any, or interest on, any such Indebtedness, after giving effect to any applicable grace period (a “Payment Default”), having a principal amount of $50,000,000 or more individually or, taken together with the principal amount of any other Indebtedness under which there has been a Payment Default, in the aggregate; provided that if any such default is cured or waived or any such acceleration is rescinded, or such Indebtedness is repaid, within a period of 30 days from the continuation of such default beyond any applicable grace period or the occurrence of such acceleration, as the case may be, such Event of Default and any consequent acceleration of the Securities shall be rescinded, so long as any such rescission does not conflict with any judgment or decree or applicable provision of law;

(5) default in the performance, or breach of, the covenant set forth in Article Five, or in the performance, or breach of, any other covenant or agreement of the Company or any Subsidiary Guarantor in this Indenture and failure to remedy such default within a period of 45 days after written notice thereof from the Trustee or Holders of 25% of the principal amount of the outstanding Securities;

(6) the entry by a court of one or more judgments or orders for the payment of money against the Company, any Subsidiary Guarantor or any other Subsidiary in an aggregate amount in excess of $50,000,000 (net of applicable insurance coverage by a third party insurer which is acknowledged in writing by such insurer) that has not been vacated, discharged, satisfied or stayed pending appeal within 60 days from the entry thereof;

(E) admits in writing that it generally is unable to pay its debts as the same become due; or

(9) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that:

(A) is for relief (with respect to the petition commencing such case) against the Company or any Subsidiary in an involuntary case or proceeding,

(B) appoints a Custodian of the Company or any Subsidiary or for all or substantially all of its property, or

(C) orders the liquidation of the Company or any Subsidiary, and the order or decree remains unstayed and in effect for 60 days.

The term “Bankruptcy Law” means Title 11, U.S. Code or any similar federal or state law for the relief of debtors. The term “Custodian” means any receiver, trustee, assignee, liquidator or similar official under any Bankruptcy Law.

SECTION 6.02. Acceleration. If an Event of Default (other than an Event of Default specified in clauses (8) or (9)) under Section 6.01 occurs and is continuing, then and in every such case the Trustee or the Holders of not less than 25% of the principal amount of the outstanding Securities may declare the unpaid principal of and premium, if any, or the Net Proceeds Offer purchase price if the Event of Default includes failure to pay the Net Proceeds Offer purchase price, and accrued and unpaid interest on, all the Securities then outstanding to be due and payable, by a notice in writing to the Company (and to the Trustee, if given by Holders), and upon any such declaration such principal, premium, if any, and accrued and unpaid interest shall become immediately due and payable, notwithstanding anything contained in this Indenture or the Securities to the contrary. If an Event of Default specified in clauses 8 or 9 above occurs, all unpaid principal of, and premium, if any, and accrued and unpaid interest on, the Securities then outstanding will become due and payable, without any declaration or other act on the part of the Trustee or any Holder.

The Holders of a majority of the principal amount of the outstanding Securities, by written notice to the Company, the Subsidiary Guarantors and the Trustee, may rescind and annul a declaration of acceleration and its consequences if (1) the Company or any Subsidiary Guarantor has paid or deposited with such Trustee a sum sufficient to pay (A) all overdue installments of interest on all the Securities, (B) the principal of, and premium, if any, on any Securities that have become due otherwise than by such declaration of acceleration and interest thereon at the rate or rates prescribed therefor in the Securities, (C) to the extent that payment of such interest is lawful, interest on the defaulted interest at the rate or rates prescribed therefor in the Securities, and (D) all money paid or advanced by the Trustee thereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; (2) all Events of Default, other than the non-payment of the

29

principal of any Securities that have become due solely by such declaration of acceleration, have been cured or waived as provided in this Indenture; and (3) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction. No such rescission will affect any subsequent Event of Default or impair any right consequent thereon.

SECTION 6.03. Other Remedies. If an Event of Default occurs and is continuing, the Trustee may, but is not obligated to, pursue, in its own name and as trustee of an express trust, any available remedy by proceeding at law or in equity to collect the payment of principal or interest on the Securities or to enforce the performance of any provision of the Securities or this Indenture. If an Event of Default specified under clauses (8) or (9) of Section 6.01 occurs with respect to the Company at a time when the Company is the Paying Agent, the Trustee shall automatically assume the duties of Paying Agent.

The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative.

SECTION 6.04. Waiver of Past Defaults. Subject to Sections 6.07 and 9.02, the Holders of at least a majority of the principal amount of the outstanding Securities by notice to the Trustee may waive an existing Default or Event of Default and its consequences, except a Default or Event of Default in payment of principal or interest on the Securities, including any make-whole redemption payments or Net Proceeds Offer payments.

SECTION 6.05. Control by Majority. The Holders of a majority in principal amount of the Securities will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on such Trustee, provided that (1) such direction is not in conflict with any rule of law or with this Indenture and (2) the Trustee may take any other action deemed proper by such Trustee that is not inconsistent with such direction.

SECTION 6.06. Limitation on Remedies. No Holder of any of the Securities will have any right to institute any proceeding, judicial or otherwise, or for the appointment of a receiver or trustee or pursue any remedy under this Indenture, unless:

(1) such Holder has previously given notice to the Trustee of a continuing Event of Default,

(2) the Holders of not less than 25% of the principal amount of the outstanding Securities have made written request to such Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee under this Indenture,

30

(3) such Holder or Holders have offered to such Trustee indemnity reasonably satisfactory to it against the costs, expenses and liabilities to be incurred in compliance with such request,

(4) such Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any proceeding, and

(5) no direction inconsistent with such written request has been given to such Trustee during such 60-day period by the Holders of a majority of the principal amount of the outstanding Securities.

A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over other Holders.

SECTION 6.07. Rights of Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the Holder of any Securities will have the right, which is absolute and unconditional, to receive payment of the principal of and interest on such Securities on the stated maturity therefor and to institute suit for the enforcement of any such payment, and such right may not be impaired without the consent of such Holder.

SECTION 6.08. Collection Suit by Trustee. If an Event of Default in payment of principal, premium, if any, or interest specified in Section 6.01(1), (2) or (3) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company or any Subsidiary Guarantor for the whole amount of principal, premium, if any, and interest remaining unpaid with respect to the Securities, and interest on overdue principal and premium, if any, and, to the extent lawful, interest on overdue interest, and such further amounts as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation and expenses of the Trustee, its agents and counsel.

SECTION 6.09. Trustee May File Proofs of Claim. (a) The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and the Holders allowed in any judicial proceedings relative to the Company, the Subsidiary Guarantors, their creditors or their property and may collect and receive any money or securities or other property payable or deliverable on any such claims and to distribute the same.

(b) Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

31

SECTION 6.10. Priorities. If the Trustee collects any money pursuant to this Article Six, it shall pay out the money in the following order:

First: to the Trustee for amounts due under Section 7.07;

Second: to Holders for amounts due and unpaid on the Securities for principal and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Securities for principal and interest, respectively; and

Third: to the Company.

The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 6.10.

SECTION 6.11. Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07, or a suit by Holders of more than 10% in principal amount of the then outstanding Securities.

ARTICLE SEVEN

TRUSTEE

SECTION 7.01. Duties of Trustee. (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such rights and powers vested in it by this Indenture and use the same degree of care and skill in such exercise as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs.

(b) Except during the continuance of an Event of Default:

(1) The Trustee need perform only those duties that are specifically set forth (or incorporated by reference) in this Indenture and no others.

(2) In the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, in the case of certificates or opinions specifically required by any provision hereof to be furnished to it, the Trustee shall examine such

32

certificates and opinions to determine whether or not they conform to the requirements of this Indenture.

(c) The Trustee may not be relieved from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that:

(1) This paragraph (c) does not limit the effect of paragraph (b) of this Section.

(2) The Trustee shall not be liable for any error of judgment made in good faith by an officer of the Trustee, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts.

(3) The Trustee shall not be liable with respect to action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05, and the Trustee shall be entitled from time to time to request such a direction.

(d) Every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b) and (c) of this Section.

(e) The Trustee shall be under no obligation and may refuse to perform any duty or exercise any right, duty or power hereunder unless it receives indemnity reasonably satisfactory to it against any loss, liability or expense. No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers, if it shall have reasonable grounds to believe that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

(f) The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law.

SECTION 7.02. Rights of Trustee. Subject to Section 7.01:

(a) The Trustee may conclusively rely on and shall be fully protected in acting or refraining from acting upon any document believed by it to be genuine and to have been signed or presented by the proper person. The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney, to the extent reasonably required by such inquiry or investigation at the expense of the Company

33

and shall incur no liability of any kind by reason of such inquiry or investigation.

(b) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on such certificate or opinion.

(c) The Trustee may act through agents and shall not be responsible for the misconduct or negligence of any agent appointed with due care.

(d) The Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to be authorized or within its rights or powers.

(e) The Trustee may consult with counsel of its selection and the advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and reliance thereon.

(f) In no event shall the Trustee be responsible or liable for special, indirect, or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action.

(g) The Trustee shall not be deemed to have notice of any Default or Event of Default unless a Trust Officer has actual knowledge thereof or unless written notice of any event which is in fact such a default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Securities and this Indenture.

(h) The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other Person employed to act hereunder.

(i) The Trustee may request that the Company deliver a certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture.

SECTION 7.03. Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or its Subsidiaries or Affiliates with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. However, the Trustee must comply with Sections 7.10 and 7.11.

SECTION 7.04. Trustee’s Disclaimer. The Trustee makes no representation as to the validity or adequacy of this Indenture or the Securities, it shall not be accountable for the Company’s use of the proceeds from the Securities or any prospectus, offering or

34

solicitation documents, and it shall not be responsible for any statement in the Securities other than its certificate of authentication.

SECTION 7.05. Notice of Defaults. If a Default occurs and is continuing and if it is known to the Trustee, the Trustee shall mail to each Holder pursuant to Section 11.02 a notice of the Default within 90 days after it occurs. Except in the case of a Default in any payment on any Security, the Trustee may withhold the notice if and so long as the board of directors, executive committee or a trust committee of officers in good faith determines that withholding the notice is in the interests of Holders.

SECTION 7.06. Reports by Trustee to Holders. Within 60 days after each April 1, beginning with the April 1 following the date of this Indenture, the Trustee shall mail to each Holder a brief report dated as of such April 1 that complies with TIA Section 313(a), but only if such report is required in any year under TIA Section 313(a). The Trustee also shall comply with TIA Sections 313(b) and 313(c). A copy of each report at the time of its mailing to Holders shall be filed with the SEC and each stock exchange on which the Securities are listed. The Company shall notify the Trustee in writing when the Securities become listed on any national securities exchange or of any delisting thereof.

SECTION 7.07. Compensation and Indemnity. The Company and the Subsidiary Guarantors jointly and severally agree to pay the Trustee from time to time reasonable compensation for its services (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust). The Company and the Subsidiary Guarantors jointly and severally agree to reimburse the Trustee upon request for all reasonable out-of-pocket expenses, disbursements and advances incurred by it. Such expenses shall include when applicable the reasonable compensation and expenses of the Trustee’s agents and counsel.

The Trustee shall not be under any obligation to institute any suit, or take any remedial action under this Indenture, or to enter any appearance or in any way defend any suit in which it may be a defendant, or to take any steps in the execution of the trusts created hereby or thereby or in the enforcement of any rights and powers under this Indenture, until it shall be indemnified to its satisfaction against any and all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provisions of this Indenture, including compensation for services, costs, expenses, outlays, counsel fees and other disbursements, and against all liability (including fees and expenses incurred by the Trustee pursuant to the penultimate paragraph of Section 7.08) not due to its negligence or willful misconduct. The Company and the Subsidiary Guarantors jointly and severally agree to indemnify the Trustee against any loss, liability, claim, damage or expenses incurred by it arising out of or in connection with the acceptance and administration of the trust and its duties hereunder as Trustee, Registrar and/or Paying Agent, including the costs and expenses of enforcing this Indenture against the Company (including with respect to this Section 7.07) and of defending itself against any claim or liability in connection with the

35

exercise or performance of any of its powers or duties hereunder. The Trustee shall notify the Company and the Subsidiary Guarantors of any claim of which a Trust Officer has received written notice for which it may seek indemnity; however, unless the position of the Company is prejudiced by such failure, the failure of the Trustee to promptly notify the Company shall not limit its right to indemnification. The Company shall defend each such claim and the Trustee shall cooperate in the defense. The Trustee may retain separate counsel and the Company shall reimburse the Trustee for the reasonable fees and expenses of such counsel. The Company need not pay for any settlement made without its consent.

Neither the Company nor the Subsidiary Guarantors shall be obligated to reimburse any expense or indemnify against any loss or liability incurred by the Trustee through the Trustee’s own negligence or willful misconduct. To secure the payment obligations of the Company and the Subsidiary Guarantors in this Section, the Trustee shall have a claim prior to that of the Holders of the Securities on all money or property held or collected by the Trustee, except that held in trust to pay principal of and interest on particular Securities. The Trustee’s right to receive payment of any amounts due under this Section 7.07 shall not be subordinate to any other liability or Indebtedness of the Company.

When the Trustee incurs expenses or renders services after the occurrence of any Event of Default specified in Sections 6.01(8) or (9), the expenses and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law.

The benefits of this section shall survive termination of this Indenture and resignation or removal of the Trustee.

SECTION 7.08. Replacement of Trustee. The Trustee may resign by so notifying the Company and the Subsidiary Guarantors. The Holders of a majority in principal amount of the Securities may remove the Trustee by so notifying the Trustee, in writing. The Company may remove the Trustee if:

(1) the Trustee fails to comply with Section 7.10;

(2) the Trustee is adjudged a bankrupt or an insolvent;

(3) a receiver or other public officer takes charge of the Trustee or its property; or

(4) the Trustee becomes incapable of acting as Trustee hereunder.

If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the Securities may appoint a successor Trustee to replace the successor Trustee appointed by the Company.

36

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company and the Subsidiary Guarantors. Immediately after that and upon payment of its charges hereunder, the retiring Trustee shall transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.07, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. A successor Trustee shall mail notice of its succession to each Holder.

If a successor Trustee does not take office within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of a majority in principal amount of the Securities may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor Trustee.

If the Trustee fails to comply with Section 7.10, any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. Any successor Trustee shall comply with TIA Section 310(a)(5).

SECTION 7.09. Successor Trustee by Merger, etc. If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust assets to, another corporation, the successor corporation without any further act shall be the successor Trustee; provided such corporation or association shall be otherwise eligible and qualified under this Article and shall notify the Company of its successor hereunder.

SECTION 7.10. Eligibility; Disqualification. This Indenture shall always have a Trustee which satisfies the requirements of TIA Section 310(a)(1).

DISCHARGE OF INDENTURE

SECTION 8.01. Option to Effect Legal Defeasance or Covenant Defeasance.

The Company may, at the option of its Board of Directors evidenced by a resolution set forth in an Officers’ Certificate, at any time, with respect to the Securities, elect to exercise its rights pursuant to either Section 8.02 or 8.03 with respect to all outstanding Securities upon compliance with the conditions set forth below in this Article Eight.

37

SECTION 8.02. Legal Defeasance and Discharge. Upon the Company’s exercise under Section 8.01 of the option applicable to this Section 8.02, the Company shall be deemed to have been discharged from its obligations with respect to all outstanding Securities on the date all conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, such Legal Defeasance means that the Company shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Securities, which shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 and the other Sections of this Indenture referred to in (a) and (b) below, and to have satisfied all its other obligations under such Securities and this Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following which shall survive until otherwise terminated or discharged hereunder: (a) the rights of Holders of outstanding Securities to receive solely from the trust fund described in Section 8.04, and as more fully set forth in such Section, payments in respect of the principal of, premium, if any, and interest on such Securities when such payments are due, (b) the Company’s obligations with respect to such Securities under Sections 2.03, 2.04, 2.06, 2.07, 2.09 and 4.04, (c) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Company’s obligations in connection therewith (including, but not limited to, Section 7.07) and (d) this Article Eight. Subject to compliance with this Article Eight, the Company may exercise its option under this Section 8.02 notwithstanding the prior exercise of its option under Section 8.03 with respect to the Securities.

SECTION 8.03. Covenant Defeasance. Upon the Company’s exercise under Section 8.01 of the option applicable to this Section 8.03, the Company shall be released from its obligations under the covenants contained in the second sentence of Section 4.02, Sections 4.03, 4.07, 4.08, 4.09 and 4.10 and Article Five with respect to the outstanding Securities on and after the date the conditions set forth below are satisfied (hereinafter, “Covenant Defeasance”), and the Securities shall thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Securities shall not be deemed outstanding for accounting purposes). For this purpose, such Covenant Defeasance means that, with respect to the outstanding Securities, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.01(5), but, except as specified above, the remainder of this Indenture and such Securities shall be unaffected thereby. In addition, upon the Company’s exercise under Section 8.01 of the option applicable to this Section 8.03, Sections 6.01(4) through 6.01(9) shall not constitute Events of Default.

SECTION 8.04. Conditions to Legal or Covenant Defeasance. The following shall be the conditions to application of either Section 8.02 or Section 8.03 to the outstanding Securities:

(b) In the case of an election under Section 8.02, the Company shall have delivered to the Trustee an Opinion of Counsel confirming that (i) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (ii) since the date hereof, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the Holders of the outstanding Securities 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;

(c) In the case of an election under Section 8.03, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of the outstanding Securities 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;

(d) No Default or Event of Default with respect to the Securities shall have occurred and be continuing on the date of such deposit or, insofar as Subsection 6.01(8) or 6.01(9) is concerned, at any time in the period ending on the 91st day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period);

(e) Such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, this

39

Indenture or any other material agreement or instrument to which the Company is a party or by which the Company is bound;

(f) In the case of any election under Section 8.02 or 8.03, the Company shall have delivered to the Trustee an Officers’ Certificate stating that the deposit made by the Company pursuant to its election under Section 8.02 or 8.03 was not made by the Company with the intent of preferring the Holders over other creditors of the Company or with the intent of defeating, hindering, delaying or defrauding creditors of the Company or others; and

(g) The Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for relating to either the Legal Defeasance under Section 8.02 or the Covenant Defeasance under Section 8.03 (as the case may be) have been complied with as contemplated by this Section 8.04.

SECTION 8.05. Deposited Money and U.S. Government Securities to be Held in Trust; Other Miscellaneous Provisions. Subject to Section 8.06, all money and U.S. Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04 in respect of the outstanding Securities shall be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Company or a Subsidiary Guarantor, if any, acting as Paying Agent) as the Trustee may determine, to the Holders of such Securities of all sums due and to become due thereon in respect of principal, premium, if any, and interest, but such money need not be segregated from other funds except to the extent required by law.

The Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or U.S. Government Securities deposited pursuant to Section 8.04 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Securities.

Anything in this Article Eight to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon the Company’s request any money or U.S. Government Securities held by it as provided in Section 8.04 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(a)), are in excess of the amount thereof which would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

SECTION 8.06. Repayment to Company. Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, premium, if any, or interest on any Security which is not subject to the last paragraph of Section 8.05 and has remained unclaimed for two years after such principal, and

40

premium, if any, or interest has become due and payable shall be paid to the Company on its request (unless an abandoned property law designates another Person) or (if then held by the Company) shall be discharged from such trust; and the Holder of such Securities shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in the New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining will be repaid to the Company.

SECTION 8.07. Reinstatement. If the Trustee or Paying Agent is unable to apply any U.S. Legal Tender or U.S. Government Securities in accordance with Section 8.02 or 8.03, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining, or otherwise prohibiting such application, then the Company’s obligations under this Indenture and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03, as the case may be; provided, however, that, if the Company makes any payment of principal of, premium, if any, or interest on any Security following the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money held by the Trustee or Paying Agent. In the event the Company’s obligations under this Indenture and the Securities are revived and reinstated pursuant to this Section 8.07, then the obligations of each Subsidiary Guarantor under its Guarantee and this Indenture that were released pursuant to Section 10.04 as a result of the Company’s exercise of its rights under this Article Eight shall be revived and reinstated as though such release had not occurred.

ARTICLE NINE

AMENDMENTS, SUPPLEMENTS AND WAIVERS

SECTION 9.01. Without Consent of Holders.

The Company, the Subsidiary Guarantors and the Trustee may amend or supplement this Indenture or the Securities without notice to or consent of any Holder:

(1) to cure any ambiguity, omission, defect or inconsistency;

(2) to comply with Section 5.01 or 10.02;

(3) to reflect the addition or release of any Subsidiary Guarantor, as provided for by this Indenture;

41

(4) to comply with any requirements of the SEC in order to effect or maintain the qualification of this Indenture under the TIA; or

(5) to make any change that would provide any additional benefit or rights to the Holders or that does not adversely affect the rights of any Holder in any material respect.

Upon the request of the Company and the Subsidiary Guarantors, accompanied by a Board Resolution of the Company and of each Subsidiary Guarantor authorizing the execution of any such supplemental indenture, and upon receipt by the Trustee of the documents described in Section 9.06, the Trustee shall join with the Company and the Subsidiary Guarantors in the execution of any supplemental indenture authorized or permitted by the terms of this Indenture and make any further appropriate agreements and stipulations that may be therein contained. After an amendment or waiver under this Section becomes effective, the Company shall mail to the Holders of each Security affected thereby a notice briefly describing the amendment or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such supplemental indenture.

SECTION 9.02. With Consent of Holders. Except as provided below in this Section 9.02, the Company, the Subsidiary Guarantors and the Trustee may amend this Indenture or the Securities with the written consent (including consents obtained in connection with a tender offer or exchange offer for Securities or a solicitation of consents in respect of Securities, provided that in each case such offer or solicitation is made to all Holders of then outstanding Securities on equal terms) of the Holders of at least a majority of the principal amount of the outstanding Securities.

Upon the request of the Company and the Subsidiary Guarantors, accompanied by a Board Resolution of the Company and each Subsidiary Guarantor authorizing the execution of any such supplemental indenture, and upon the filing with the Trustee of evidence of the consent of the Holders as aforesaid, and upon receipt by the Trustee of the Opinion of Counsel described in Section 9.06, the Trustee shall join with the Company and the Subsidiary Guarantors in the execution of such supplemental indenture.

It shall not be necessary for the consent of the Holders under this Section to approve the particular form of any proposed amendment or waiver, but it shall be sufficient if such consent approves the substance thereof.

The Holders of a majority of the principal amount of the outstanding Securities may waive compliance in a particular instance by the Company or the Subsidiary Guarantors with any provision of this Indenture or the Securities (including waivers obtained in connection with a tender offer or exchange offer for Securities or a solicitation of consents in respect of Securities, provided that in each case such offer or solicitation is made to all Holders of the then outstanding

42

Securities on equal terms). However, without the consent of each Holder affected, an amendment or waiver under this Section may not:

(1) reduce the percentage of principal amount of Securities whose Holders must consent to an amendment, supplement or waiver of any provision of this Indenture or the Securities;

(2) reduce the rate or change the time for payment of interest, including default interest, on the Securities;

(3) reduce the principal amount of any Security or change the Maturity Date of the Securities;

(4) reduce the redemption price, including premium, if any, payable upon the redemption of any Security or change the time at which any Security may be redeemed;

(5) reduce the repurchase price payable upon the repurchase of any Security in connection with a Net Proceeds Offer, or change the time at which any Security may or shall be repurchased thereunder;

(6) waive a Default or Event of Default in the payment of the principal of, premium, if any, or interest on the Securities;

(7) make any Security payable in money other than that stated in the Security;

(8) impair the right to institute suit for the enforcement of principal of, premium, if any, or principal on any Security pursuant to Sections 6.07 or 6.08, except as limited by Section 6.06; or

(9) make any change in Section 6.04 or Section 6.07 or in this sentence of this Section 9.02.

The right of any Holder to participate in any consent required or sought pursuant to any provision of this Indenture (and the obligation of the Company to obtain any such consent otherwise required from such Holder) may be subject to the requirement that such Holder shall have been the Holder of record of any Securities with respect to which such consent is required or sought as of a date identified by the Trustee in a notice furnished to Holders in accordance with the terms of this Indenture.

SECTION 9.03. Compliance with Trust Indenture Act. Every amendment to or supplement of this Indenture or the Securities shall comply with the TIA as then in effect.

SECTION 9.04. Revocation and Effect of Consents. A consent to an amendment, supplement or waiver by a Holder of a Security shall bind the Holder and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent is not made on any Security.

43

However, until an amendment, supplement or waiver becomes effective, any such Holder or subsequent Holder may revoke the consent as to its Security or portion of a Security. For such revocation to be effective, the Trustee must receive the notice of revocation before the date the amendment, supplement or waiver becomes effective.

The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any amendment or waiver. If the Company elects to fix a record date for such purpose, the record date shall be fixed at (i) the later of 30 days prior to the first solicitation of such consent or the date of the most recent list of Holders furnished to the Trustee prior to such solicitation pursuant to Section 2.05, or (ii) such other date as the Company shall designate. If a record date is fixed, then notwithstanding the provisions of the immediately preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to consent to such amendment or waiver or to revoke any consent previously given, whether or not such Persons continue to be Holders after such record date. No consent shall be valid or effective for more than 90 days after such record date unless consent from the Holders of the principal amount of Securities required hereunder for such amendment or waiver to be effective also shall have been given and not revoked within such 90-day period.

After an amendment, supplement or waiver becomes effective, it shall bind every Holder unless it makes a change described in any of clauses (1) through (9) of Section 9.02. In that case the amendment, supplement or waiver shall bind each Holder of a Security who has consented to it and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security.

SECTION 9.05. Notation on or Exchange of Senior Notes. If an amendment, supplement or waiver changes the terms of a Security, the Trustee may require the Holder of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security about the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms.

SECTION 9.06. Trustee Protected. The Trustee shall sign any amendment or supplement or waiver authorized pursuant to this Article if the amendment or supplement or waiver does not adversely affect the rights of the Trustee. If it does adversely affect the rights of the Trustee, the Trustee may but need not sign it. In signing such amendment or supplement or waiver the Trustee shall be provided with, and (subject to Article Seven) shall be fully protected in relying upon, an Opinion of Counsel stating that such amendment or supplement or waiver is authorized or permitted by and complies with this Indenture. The Company may not sign an amendment or supplement until the Boards of Directors of the Company and the Subsidiary Guarantors approve it.

ARTICLE TEN

GUARANTEES

SECTION 10.01. Unconditional Guarantee. Each Subsidiary Guarantor hereby, jointly and severally, fully and unconditionally guarantees, as principal obligor and not only as surety (such guarantee to be referred to herein as the “Guarantee”), to each Holder and to the Trustee the due and punctual payment of the principal of, premium, if any, and interest on the Securities and all other amounts due and payable under this Indenture and the Securities by the Company whether at maturity, by acceleration, redemption, repurchase or otherwise, including, without limitation, interest on the overdue principal of, premium, if any, and interest on the Securities, to the extent lawful, all in accordance with the terms hereof and thereof; subject, however, to the limitations set forth in Section 10.05.

Failing payment when due of any amount so guaranteed for whatever reason, the Subsidiary Guarantors will be jointly and severally obligated to pay the same immediately. Each Subsidiary Guarantor hereby agrees that its obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Securities or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Securities with respect to any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Subsidiary Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that this Guarantee will not be discharged except by complete performance of the obligations contained in the Securities, this Indenture and in this Guarantee. If any Holder or the Trustee is required by any court or otherwise to return to the Company, any Subsidiary Guarantor, or any custodian, trustee, liquidator or other similar official acting in relation to the Company or any Subsidiary Guarantor, any amount paid by the Company or any Subsidiary Guarantor to the Trustee or such Holder, this Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. Each Subsidiary Guarantor agrees it shall not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Subsidiary Guarantor further agrees that, as between each Subsidiary Guarantor, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article Six for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any acceleration of such obligations as provided in Article Six, such obligations (whether or not due and payable) shall forthwith become due and payable by each Subsidiary Guarantor for the purpose of this Guarantee.

SECTION 10.02. Subsidiary Guarantors May Consolidate, etc., on Certain Terms. (a) Subject to paragraph (b) of this Section 10.02, no

45

Subsidiary Guarantor may consolidate or merge with or into (whether or not such Subsidiary Guarantor is the surviving Person) another Person unless (i) the Person formed by or surviving any such consolidation or merger (if other than such Subsidiary Guarantor) assumes all the obligations of such Subsidiary Guarantor under this Indenture and the Securities pursuant to a supplemental indenture, in a form reasonably satisfactory to the Trustee and (ii) immediately after such transaction, no Default or Event of Default exists. In connection with any consolidation or merger contemplated by this Section 10.02, the Company shall deliver to the Trustee prior to the consummation of the proposed transaction an Officers’ Certificate to the foregoing effect and an Opinion of Counsel stating that the proposed transaction and such supplemental indenture comply with this Indenture. This Section 10.02(a) will not prohibit a merger between Subsidiary Guarantors or a merger between the Company and a Subsidiary Guarantor.

(b) In the event of a sale or other disposition of all or substantially all of the assets of any Subsidiary Guarantor or a sale or other disposition of all of the Capital Stock of such Subsidiary Guarantor, in any case by way of merger, consolidation or otherwise, 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 assets (in the event of a sale or other disposition of all or substantially all of the assets of such Subsidiary Guarantor) will be released and relieved of any obligations under its Guarantees.

SECTION 10.03. Addition of Subsidiary Guarantors. (a) The Company agrees to cause each domestic Subsidiary that shall become a Subsidiary after the Issue Date and that guarantees any other Indebtedness of the Company or a Subsidiary Guarantor in excess of a De Minimis Guaranteed Amount to execute and deliver a supplemental indenture pursuant to which such Subsidiary shall guarantee the payment of the Securities pursuant to the terms hereof within 180 days after the later of (i) the date that Subsidiary becomes a domestic Subsidiary and (ii) the date that Subsidiary guarantees such other Indebtedness; provided that no guarantee shall be required if the Subsidiary merges into the Company or an existing Subsidiary Guarantor and the surviving entity remains a Subsidiary Guarantor.

(b) Any Person that was not a Subsidiary Guarantor on the Issue Date may become a Subsidiary Guarantor by executing and delivering to the Trustee (i) a supplemental indenture in form and substance satisfactory to the Trustee, which subjects such Person to the provisions (including the representations and warranties) of this Indenture as a Subsidiary Guarantor and (ii) an Opinion of Counsel and Officers’ Certificate to the effect that such supplemental indenture has been duly authorized and executed by such Person and constitutes the legal, valid and binding obligation of such Person (subject to such customary exceptions concerning creditors’ rights and equitable principles as may be acceptable to the Trustee in its discretion and provided that no opinion need be rendered concerning the enforceability of the Guarantee).

SECTION 10.04. Release of a Subsidiary Guarantor. Upon (i) the sale or disposition of a Subsidiary Guarantor (or all or substantially

46

all of its assets) or (ii) the cessation by a Subsidiary Guarantor to guarantee any other Indebtedness of the Company or any other Subsidiary Guarantor other than a De Minimis Guaranteed Amount, in each case which is otherwise in compliance with the terms of this Indenture, including but not limited to the provisions of Section 10.02, such Subsidiary Guarantor shall be deemed released from all of its Guarantee and related obligations in this Indenture without any further action by the Trustee, the Company or such Subsidiary Guarantor. Subject to Section 8.07, upon the Company’s election, in compliance with the conditions set forth in Article Eight hereof, to exercise its rights pursuant to either Section 8.02 or 8.03 with respect to all outstanding Securities, each Subsidiary Guarantor shall be deemed released from all of its Guarantee and related obligations in this Indenture without any further action by the Trustee, the Company or any Subsidiary Guarantor. The Trustee shall deliver an appropriate instrument evidencing such release upon receipt of a request by the Company accompanied by an Officers’ Certificate and, in the case of the release of a Subsidiary Guarantor pursuant to clause (i) of the first sentence of this Section 10.04, an Opinion of Counsel certifying that such sale or other disposition was made by the Company in accordance with the provisions of this Indenture. Any Subsidiary Guarantor not so released remains liable for the full amount of principal of and interest on the Securities as provided in this Article Ten.

SECTION 10.05. Limitation of Subsidiary Guarantor’s Liability. Each Subsidiary Guarantor, and by its acceptance hereof each Holder, hereby confirms that it is the intention of all such parties that the guarantee by such Subsidiary Guarantor pursuant to its Guarantee not constitute a fraudulent transfer or conveyance for purposes of any federal, state or foreign law. To effectuate the foregoing intention, the Holders and each Subsidiary Guarantor hereby irrevocably agree that the obligations of each Subsidiary Guarantor under the Guarantee shall be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Subsidiary Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Subsidiary Guarantor in respect of the obligations of such other Subsidiary Guarantor under its Guarantee or pursuant to Section 10.06, result in the obligations of such Subsidiary Guarantor under the Guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal, state or foreign law. This Section 10.05 is for the benefit of the creditors of each Subsidiary Guarantor, and, for purposes of applicable fraudulent transfer and fraudulent conveyance law, any Indebtedness of a Subsidiary Guarantor pursuant to Credit Facilities shall be deemed to have been incurred prior to the incurrence by such Subsidiary Guarantor of its liability under the Guarantee.

SECTION 10.06. Contribution. In order to provide for just and equitable contribution among the Subsidiary Guarantors, the Subsidiary Guarantors agree, inter se, that in the event any payment or distribution is made by any Subsidiary Guarantor (a “Funding Guarantor”) under the Guarantee, such Funding Guarantor shall be entitled to a contribution from each other Subsidiary Guarantor in a pro rata amount based on the Adjusted Net Assets of each Subsidiary Guarantor (including the Funding Guarantor) for all payments, damages and expenses incurred by the Funding Guarantor in discharging the

47

Company’s obligations with respect to the Securities or any other Subsidiary Guarantor’s obligations with respect to the Guarantee.

SECTION 10.07. [Intentionally Omitted.]

SECTION 10.08. Severability. In case any provision of this Guarantee shall be invalid, illegal or unenforceable, that portion of such provision that is not invalid, illegal or unenforceable shall remain in effect, and the validity, legality, and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

Members of, or participants in, the Depository (“Agent Members”) shall have no rights under this Indenture with respect to any Global Security held on their behalf by the Depository or by the Trustee as Securities Custodian or under such Global Security, and the Company, the Trustee and any agent of the Company or the Trustee shall be entitled to treat the Depository as the absolute owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depository or impair, as between the Depository and its Agent Members, the operation of customary practices of such Depository governing the exercise of the rights of a holder of a beneficial interest in any Global Security.

At such time as all beneficial interests in a Global Security have either been exchanged for certificated Securities, redeemed, purchased or canceled, such Global Security shall be returned to the Depository for cancelation or retained and canceled by the Trustee. At any time prior to such cancelation, if any beneficial interest in a Global Security is exchanged for certificated Securities, redeemed, purchased or canceled, the principal amount of Securities represented by such Global Security shall be reduced and an adjustment shall be made on the books and records of the Trustee (if it is then the Securities Custodian for such Global Security) with respect to such Global Security, by the Trustee or the Securities Custodian, to reflect such reduction.

(iv) Prior to the due presentation for registration of transfer of any Security, the Company, the Trustee, the Paying Agent, the Registrar or any co-registrar may deem and treat the person in whose name a Security is registered as the absolute owner of such Security for the purpose of receiving payment of principal of and interest on such Security and for all other purposes whatsoever, whether or not such Security is overdue, and none of the Company, the Trustee, the Paying Agent, the Registrar or any co-registrar shall be affected by notice to the contrary.

All notices and communications to be given to the Holders and all payments to be made to Holders under the Securities shall be given or made only to or upon the order of the registered Holders (which shall be the Depository or its nominee in the case of a Global Security). The rights of beneficial owners in any Global Security shall be exercised only through the Depository subject to the applicable rules and procedures of the Depository. The Trustee may rely and shall be fully protected in relying upon information furnished by the Depository with respect to its Agent Member and any beneficial owners.

(ii) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Security (including any transfers between or among Agent Members or beneficial owners in any Global Security) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

57

[REVERSE SIDE OF SECURITY]

[     ]% Senior Note due 2013

1. Interest

Chesapeake Energy Corporation, an Oklahoma corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred to, being herein called the “Company”), promises to pay interest on the principal amount of this Security at the rate per annum shown above. The Company will pay interest semiannually on [            ] and [            ] of each year, commencing [            ], 2006. Interest on the Securities will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from [            ], 2006. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

2. Method of Payment

The Company will pay interest on the Securities (except defaulted interest) to the Persons who are registered holders of Securities at the close of business on the [            ] or [            ] next preceding the interest payment date even if Securities are canceled after the record date and on or before the interest payment date. Holders must surrender Securities to a Paying Agent to collect principal payments. The Company will pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. Payments in respect of the Securities represented by a Global Security (including principal, premium and interest) will be made by wire transfer of immediately available funds to the accounts specified by The Depository Trust Company. The Company will make all payments in respect of a certificated Security (including principal, premium and interest) by mailing a check to the registered address of each Holder thereof; provided, however, that payments on a certificated Security will be made by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than 30 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion).

3. Paying Agent and Registrar

Initially, The Bank of New York Trust Company, N.A., a national banking association (the “Trustee”), will act as Paying Agent and Registrar. The Company may appoint and change any Paying Agent, Registrar or co-registrar without notice. The Company or any of its domestically incorporated Wholly Owned Subsidiaries may act as Paying Agent, Registrar or co-registrar.

4. Indenture

The Company issued the Securities under an Indenture dated as of [            ], 2006 (“Indenture”), among the Company, the Subsidiary

Guarantors and the Trustee. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) as in effect on the date of the Indenture (the “Act”). Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture. The Securities are subject to all such terms, and Holders are referred to the Indenture and the Act for a statement of those terms.

The Company shall be entitled to issue Additional Securities pursuant to Section 2.13 of the Indenture. The Securities issued on the Issue Date and any Additional Securities will be treated as a single class for all purposes under the Indenture.

5. Make-Whole Price Redemption

At any time prior to the Maturity Date, the Company may, at its option, redeem all or any portion of the Securities at the “Make-Whole Price” (as defined in the Indenture) plus accrued and unpaid interest on the Securities so redeemed to the date of redemption. Any redemption pursuant to this paragraph 5 shall be made, to the extent applicable, pursuant to the provisions of Sections 3.01 through 3.06 of the Indenture.

6. Notice of Redemption

Notice of redemption will be mailed to the Holder’s registered address at least 30 days but not more than 60 days before the redemption date to each Holder of Securities to be redeemed. If less than all Securities are to be redeemed, the Trustee shall select pro rata, by lot or, if the Securities are listed on any securities exchange, by any other method that the Trustee considers fair and appropriate and that complies with the requirements of such exchange, the Securities to be redeemed in multiples of $1,000; provided, however, that no Securities with a principal amount of $1,000 or less will be redeemed in part. Securities in denominations larger than $1,000 may be redeemed in part. On and after the redemption date, interest ceases to accrue on Securities or portions of them called for redemption (unless the Company shall default in the payment of the redemption price or accrued interest).

7. Net Proceeds Offer

In the event of certain Sale/Leaseback Transactions, the Company may be required to make a Net Proceeds Offer to purchase all or any portion of each Holder’s Securities, at 100% of the principal amount thereof, plus accrued and unpaid interest to the Net Proceeds Payment Date.

8. Restrictive Covenants

The Indenture imposes certain limitations on, among other things, the ability of the Company to merge or consolidate with any other Person or sell and lease back certain of its properties or assets and the ability of the Company or the Subsidiaries to incur

encumbrances against certain property, all subject to certain limitations described in the Indenture.

9. Ranking and Guarantees

The Securities are general senior unsecured obligations of the Company. The Company’s obligation to pay principal, premium, if any, and interest with respect to the Securities is unconditionally guaranteed on a senior basis, jointly and severally, by the Subsidiary Guarantors pursuant to Article Ten of the Indenture. Certain limitations to the obligations of the Subsidiary Guarantors are set forth in further detail in the Indenture.

10. Denominations; Transfer; Exchange

The Securities are in registered form without coupons in denominations of $1,000 principal amount and whole multiples of $1,000. A Holder may transfer or exchange Securities in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Registrar need not register the transfer of or exchange of any Securities selected for redemption (except, in the case of a Security to be redeemed in part, the portion of the Security not to be redeemed) or any Securities for a period of 15 Business Days before the mailing of a notice of an offer to repurchase or redeem Securities or 15 Business Days before an interest payment date.

11. Persons Deemed Owners

The registered Holder of this Security may be treated as the owner of it for all purposes.

12. Unclaimed Money

If money for the payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent shall pay the money back to the Company at its request unless an abandoned property law designates another Person. After any such payment, Holders entitled to the money must look only to the Company and not to the Trustee for payment.

13. Discharge and Defeasance

Subject to certain conditions, the Company at any time shall be entitled to terminate some or all of its obligations under the Securities and the Indenture if the Company deposits with the Trustee money or U.S. Government Securities for the payment of principal and interest on the Securities to redemption or maturity, as the case may be.

14. Amendment, Supplement, Waiver

Subject to certain exceptions, the Indenture or the Securities may be amended or supplemented with the consent of the Holders of at least a majority of the outstanding principal amount of

the Securities, and any past default or noncompliance with any provision may be waived with the consent of the Holders of a majority in principal amount of the Securities. Without the consent of any Holder, the Company may amend or supplement the Indenture or the Securities to, among other things, cure any ambiguity, defect or inconsistency or to make any change that does not adversely affect the rights of any Holder in any material respect.

15. Successor Corporation

When a successor corporation assumes all the obligations of its predecessor under the Securities and the Indenture, the predecessor corporation will be released from those obligations.

16. Defaults and Remedies

An Event of Default generally is: default by the Company or any Subsidiary Guarantor for 30 days in payment of interest on the Securities; default by the Company or any Subsidiary Guarantor in payment of principal of, or premium, if any, on the Securities; default by the Company or any Subsidiary Guarantor in the deposit of any optional redemption or repurchase payment when due and payable; defaults resulting in acceleration prior to maturity of certain other Indebtedness or resulting from payment defaults under certain other Indebtedness; failure by the Company or any Subsidiary Guarantor for 45 days after notice to comply with any of its other agreements in the Indenture; certain final judgments against the Company or Subsidiaries; a failure of any Guarantee of a Subsidiary Guarantor to be in full force and effect or denial by any Subsidiary Guarantor of its obligations with respect thereto; and certain events of bankruptcy or insolvency. Subject to certain limitations in the Indenture, if an Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Securities may declare all the Securities to be due and payable immediately, except that in the case of an Event of Default arising from certain events of bankruptcy, insolvency or reorganization, all outstanding Securities shall become due and payable immediately without further action or notice. Holders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Securities. Subject to certain limitations, Holders of a majority in principal amount of the Securities may direct the Trustee in its exercise of any trust or power. The Company must furnish an annual compliance certificate to the Trustee.

17. Trustee Dealings with Company and Subsidiary Guarantors

The Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Securities and may otherwise deal with the Company, the Subsidiary Guarantors or their respective Subsidiaries or Affiliates with the same rights it would have if it were not Trustee.

18. No Recourse Against Others

A director, officer, employee or stockholder, as such, of the Company, any Subsidiary Guarantor or the Trustee shall not have any liability for any obligations of the Company, any Subsidiary Guarantor or the Trustee under the Securities or the Indenture or for any claim based on, in respect of or by reason of, such obligations or their creation. Each Holder by accepting a Security waives and releases all such liability. The waiver and release are part of the consideration for the issue of the Security.

19. Authentication

This Security shall not be valid until the Trustee or an authenticating agent signs the certificate of authentication on the other side of this Security.

20. Abbreviations

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

21. CUSIP Numbers

Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company will cause CUSIP numbers to be printed on the Securities as a convenience to Holders of the Securities. No representation is made as to the accuracy of such numbers as printed on the Securities and reliance may be placed only on the other identification numbers printed hereon.

22. Governing Law

THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK BUT WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY, EXCEPT TO THE EXTENT THAT THE LAWS OF THE STATE OF NEW YORK WOULD REQUIRE THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION REGARDING THE VALIDITY OF THE SECURITIES.

Ladies and Gentlemen:

We have acted as counsel for Chesapeake Energy Corporation, an Oklahoma corporation (the “Company”), in connection with the preparation of a Registration Statement on Form S-3 (the “Registration Statement”) filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), relating to the offer and sale, from time to time, pursuant to Rule 415 under the Securities Act, of unsecured debt securities of the Company (“Debt Securities”), in one or more series.

As to any facts material to the opinion contained herein, we have made no independent investigation of such facts and have relied, to the extent that we deem such reliance proper, upon certificates of public officials and officers or other representatives of the Company.

In connection with rendering the opinion set forth below, we have assumed that (i) all information contained in all documents reviewed by us is true and correct; (ii) all signatures on all documents examined by us are genuine; (iii) all documents submitted to us as originals are authentic and all documents submitted to us as copies conform to the originals of those documents; (iv) the Registration Statement, and any amendments thereto (including post-effective amendments), will have become effective and comply with all applicable laws; (v) the Indenture will have been duly qualified under the Trust Indenture Act of 1939, as amended; (vi) the Indenture, and any supplemental indenture relating to a particular series of Debt Securities, will be duly authorized, executed and delivered by the parties thereto in substantially the form reviewed by us; and (vii) a definitive purchase, underwriting or similar agreement with respect to any Debt Securities offered will have been duly authorized and validly executed and delivered by the Company and the other parties thereto.

Based on the foregoing, and subject to the assumptions, qualifications, limitations, and exceptions set forth herein, we are of the opinion that when such Debt Securities have been duly executed, authenticated, issued and delivered in accordance with the provisions of the Indenture upon payment of the consideration for such Debt Securities as provided for in the applicable definitive purchase, underwriting or similar agreement, such Debt Securities will be legally issued and will constitute valid and legally binding obligations of the Company, enforceable against the Company in accordance with their terms, except as such enforcement is subject to any applicable bankruptcy, insolvency, reorganization, fraudulent conveyance or other law relating to or affecting creditors’ rights generally and general principles of equity.

We express no opinions concerning (a) the validity or enforceability of any provisions contained in the Indenture that purport to waive or not give effect to rights to notices, defenses, subrogation or other rights or benefits that cannot be effectively waived under applicable law; or (b) the enforceability of

indemnification provisions to the extent they purport to relate to liabilities resulting from or based upon negligence or any violation of federal or state securities or blue sky laws.

The foregoing opinion is limited to the laws of the State of New York and the federal laws of the United States of America and we are expressing no opinion as to the effect of the laws of any other jurisdiction, domestic or foreign.

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the use of our name in the prospectus forming a part of the Registration Statement under the caption “Legal Matters.” In giving this consent, we do not admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act and the rules and regulations thereunder.
