Chesapeake 
 
We are one of the six largest independent natural gas producers in the United States in terms of natural gas produced, owning interests in approximately 17,000 producing oil and gas wells. Our internally-estimated proved oil and natural gas reserves as of March 31, 2004, pro forma for our recent acquisition of Greystone Petroleum LLC, were approximately 3.8 tcfe. Approximately 89% of our pro forma proved reserves by volume at March 31, 2004 were natural gas, and approximately 80% of our proved oil and natural gas reserves by volume at March 31, 2004 were located in our primary operating area—the Mid-Continent region of the United States, which includes Oklahoma, western Arkansas, southwestern Kansas and the Texas Panhandle. In addition, we are building secondary operating areas in the Permian Basin of western Texas and eastern New Mexico, in the Ark-La-Tex basin of eastern Texas and northern Louisiana and in the South Texas and Texas Gulf Coast regions. 
 
Since January 1, 1998, we have been one of the most active consolidators of onshore U.S. natural gas assets, having purchased or agreed to purchase approximately 3.3 tcfe at a total cost of approximately $3.9 billion (excluding the impact of deferred taxes in connection with certain corporate acquisitions). In 2004 to date, we have remained active in the acquisitions market. In January 2004, we purchased Permian Basin and Mid-Continent oil and gas assets by acquiring privately-held Concho Resources Inc. for cash consideration of $420 million (excluding employee severance and other miscellaneous costs). We also completed five other smaller acquisitions in 2004 for $165 million. Through these six acquisitions, we acquired an internally estimated 366 bcfe of proved oil and natural gas reserves and added 82 mmcfe to our estimated daily production. 
 
Most recently, on June 2, 2004, we acquired Greystone Petroleum LLC, a privately-held oil and natural gas company, for $425 million in cash. In this transaction, we acquired an internally-estimated 214 bcfe of proved reserves and added 45 mmcfe to our estimated daily production. 
 
Our executive offices are located at 6100 North Western Avenue, Oklahoma City, Oklahoma 73118, and our telephone number is (405) 848-8000. 
 
The Exchange Offer 
 
On May 27, 2004, we completed a private offering of the outstanding notes. As part of the private offering, we entered into a registration rights agreement with the initial purchasers of the outstanding notes in which we agreed, among other things, to deliver this prospectus to you and to use our best efforts to complete the exchange offer within 240 days after the date we issued the outstanding notes. The following is a summary of the exchange offer. 
 
Exchange Offer 	We are offering to exchange new notes for outstanding notes. 	
 
Expiration Date 	The exchange offer will expire at 5:00 p.m. New York City time, on                     , 2004, unless we decide to extend it. 	
 
1 

Table of Contents
Condition to the Exchange Offer 	The registration rights agreement does not require us to accept outstanding notes for exchange if the exchange offer or the making of any exchange by a holder of the outstanding notes would violate any applicable law or interpretation of the staff of the SEC. A minimum aggregate principal amount of outstanding notes being tendered is not a condition to the exchange offer. 	
 
Procedures for Tendering Outstanding Notes 	To participate in the exchange offer, you must follow the procedures established by The Depository Trust Company, which we call “DTC,” for tendering notes held in book-entry form. These procedures, which we call “ATOP,” require that the exchange agent receive, prior to the expiration date of the exchange offer, a computer generated message known as an “agent’s message” that is transmitted through DTC’s automated tender offer program and that DTC confirm that: 	
 
 	•	DTC has received your instructions to exchange your notes; and 	
 
 	•	you agree to be bound by the terms of the letter of transmittal. 	
 
For more details, please refer to the sections of this prospectus entitled “Exchange Offer—Terms of the Exchange Offer” and “—Procedures for Tendering.” 
 
Guaranteed Delivery Procedures 	None. 	
 
Withdrawal of Tenders 	You may withdraw your tender of outstanding notes at any time prior to the expiration date. To withdraw, you must submit a notice of withdrawal to exchange agent using ATOP procedures before 5:00 p.m. New York City time on the expiration date of the exchange offer. Please read “Exchange Offer—Withdrawal of Tenders.” 	
 
Acceptance of Outstanding Notes and Delivery of New Notes 	If you fulfill all conditions required for proper acceptance of outstanding notes, we will accept any and all outstanding notes that you properly tender in the exchange offer on or before 5:00 p.m. New York City time on the expiration date. We will return any outstanding note that we do not accept for exchange to you without expense as promptly as practicable after the expiration date. We will deliver the new notes as promptly as practicable after the expiration date and acceptance of the outstanding notes for exchange. Please refer to the section in this prospectus entitled “Exchange Offer—Terms of the Exchange Offer.” 	
 
Fees and Expenses 	We will bear all expenses related to the exchange offer. Please refer to the section in this prospectus entitled “Exchange Offer—Fees and Expenses.” 	
 
Use of Proceeds 	The issuance of the new notes will not provide us with any new proceeds. We are making this exchange offer solely to satisfy our obligations under our registration rights agreement.

Table of Contents
Consequences of Failure to Exchange Outstanding Notes 	If you do not exchange your outstanding notes in this exchange offer, you will no longer be able to require us to register the outstanding notes under the Securities Act except in the limited circumstances provided under our registration rights agreement. In addition, you will not be able to resell, offer to resell or otherwise transfer the outstanding notes unless we have registered the outstanding notes under the Securities Act, or unless you resell, offer to resell or otherwise transfer them under an exemption from the registration requirements of, or in a transaction not subject to, the Securities Act. 	
 
U.S. Federal Income Tax Considerations 	The exchange of new notes for outstanding notes in the exchange offer should not be a taxable event for U.S. federal income tax purposes. Please read “Federal Income Tax Considerations.”

You should direct questions and requests for assistance and requests for additional copies of this prospectus (including the letter of transmittal) to the exchange agent addressed as follows: The Bank of New York, Corporate Trust Operations, Reorganization Unit, 101 Barclay Street—7 East, New York, New York, 10286.

Table of Contents
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 exchange offer and the new notes should be considered carefully in deciding whether to participate in the exchange offer. 
 
Risks Related 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, future rate of growth and the carrying value of our oil and gas properties 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 availability of pipeline capacity; 	
 
 	•	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 	
 
 	•	the overall economic environment. 	
 
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 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 89% of our pro forma proved reserves at March 31, 2004 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 and preferred stock dividend payments on our indebtedness, including the new notes, and our preferred stock as such payments become due. 
 
As of March 31, 2004, we had long term indebtedness of $2.0 billion, with no amounts drawn under our $500 million bank revolving credit facility. Our long-term indebtedness represented 46% of our total book capitalization at March 31, 2004. We expect to continue to be highly leveraged in the foreseeable future. 
 
6 

Table of Contents
Our level of indebtedness and preferred stock affects our operations in several ways, including the following: 
 
 	•	a significant portion of our cash flows must be used to service our indebtedness and pay dividends on preferred stock, and our business may not generate sufficient cash flow from operations to enable us to continue to meet our obligations under our indebtedness and our stated dividends on our preferred stock; 	
 
 	•	a high level of debt and preferred stock increases our vulnerability to general adverse economic and industry conditions; 	
 
 	•	the covenants contained in the agreements governing our outstanding indebtedness may limit our ability to borrow additional funds, dispose of assets, pay dividends and make certain investments; 	
 
 	•	our debt covenants may also affect our flexibility in planning for, and reacting to, changes in the economy and in our industry, and the rights and preferences applicable to our preferred stock may limit our ability to pay dividends on our preferred stock; and 	
 
 	•	a high level of debt and preferred stock may impair our ability to obtain additional financing in the future for working capital, capital expenditures, acquisitions, general corporate or other purposes. 	
 
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 additional preferred stock increases the risk that we may default on our debt obligations, including the new notes. 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 redeterminations. We could be forced to repay a portion of our bank borrowings due to redeterminations of our borrowing base. If we are forced to do so, we may not have sufficient funds to make such repayments. If we do not have sufficient funds and are otherwise unable to negotiate renewals of our borrowings or arrange new financing, we may have to sell significant assets. Any such sale could have a material adverse effect on our business and financial results. 
 
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.

Our hedging activities may reduce the realized prices received for our oil and 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 gas revenues in the future. The fair value of our oil and gas derivative instruments outstanding as of March 31, 2004 was a liability of approximately $169 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. 	
 
Some of our commodity price and interest rate risk management arrangements require us to deliver cash collateral or other assurances of performance to the counterparties in the event that our payment obligations exceed certain levels. As of March 31, 2004, we were required to post a total of $75.0 million of collateral with our counterparties through letters of credit issued under our bank credit facility with respect to commodity price and financial risk management transactions. As of June 14, 2004, we were required to post a total of $92.0 million of collateral. Future collateral requirements are uncertain and will depend on arrangements with our counterparties, highly volatile natural gas and oil prices and fluctuations in interest rates. 
 
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 in this prospectus contain estimates of our proved reserves and the estimated future net revenues from our proved reserves as well as estimates relating to recent acquisitions. 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, 2003, approximately 26% 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 $351 million in 2004. 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, 2003 present value is based on weighted average oil and gas prices of $30.22 per barrel of oil and $5.68 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.

Table of Contents
Any changes in consumption by oil and 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 gas industry in general will affect the accuracy of the 10% discount factor. 
 
Reserve estimates of properties acquired in 2004 have not been prepared by independent petroleum engineers. Our internal estimates may not be as reliable as estimates of those reserves by independent engineers. 
 
Our estimates of proved reserves attributed to our 2004 acquisitions, including our recent acquisitions, included herein or incorporated by reference in this prospectus have not been reviewed or reported on by independent petroleum engineers. These estimates were prepared by our own engineers and professionals using criteria otherwise in compliance with SEC rules. Furthermore, our internal reserve estimates for these acquisitions are based upon data available to us which may not be as complete as data available on our other properties. Oil and gas pricing can affect estimates of quantities of proved reserves due to the impact of pricing on ultimate economic recovery. Estimates prepared by independent engineers might be different than our internal estimates. 
 
We may not have funds sufficient to make the significant capital expenditures 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 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 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 will decline over time. In addition, approximately 26% of our total estimated proved reserves by volume at December 31, 2003 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. We may not be able to successfully find and produce reserves economically in the future. In addition, we may not be able to acquire proved reserves at acceptable costs. 
 
Acquisitions may prove to be worth less than we paid because of uncertainties in evaluating recoverable reserves and potential liabilities. 
 
A significant portion of our recent growth is due 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

Table of Contents
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. 
 
Competition for producing oil and gas properties is intense and many of our competitors have financial and other resources that are substantially greater than those available to us. Therefore, 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. 
 
Additionally, 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. It is our current intention to continue focusing on acquiring properties with development and exploration potential located in the Mid-Continent, South Texas, Ark-La-Tex and Permian regions. To the extent that we acquire properties substantially different from the properties in our primary operating regions 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. 
 
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 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 aggregate present value of future net revenues plus the value of the unproved properties would equal the recorded net book value of our oil and gas properties at December 31, 2003, assuming an index price of approximately $3.25 per mcf for gas and $32.25 per barrel for oil. If index prices were to fall below these levels, we could experience a write-down of the book value of our oil and gas assets. 
 
Oil and gas drilling and producing operations are hazardous and expose us to environmental liabilities. 
 
Oil and 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; 	
 
10 

Table of Contents
 	•	pollution or other environmental damage; 	
 
 	•	clean-up responsibilities; 	
 
 	•	regulatory investigations and penalties; and 	
 
 	•	suspension of operations. 	
 
Our liability for environmental hazards includes those created either by the previous owners of properties that we purchase or lease or by acquired companies prior to the date we acquire them. We 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. 
 
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 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: 
 
 	•	unexpected drilling conditions; 	
 
 	•	title problems; 	
 
 	•	pressure or irregularities in formations; 	
 
 	•	equipment failures or accidents; 	
 
 	•	adverse weather conditions; 	
 
 	•	compliance with environmental and other governmental requirements; and 	
 
 	•	cost of, or shortages or delays in the availability of, drilling rigs and equipment. 	
 
The loss of key personnel could adversely affect our ability to operate. 
 
We depend, and will continue to depend in the foreseeable future, on the services of our officers and key employees with extensive experience and expertise in evaluating and analyzing producing oil and gas properties and drilling prospects, maximizing production from oil and gas properties, marketing oil and gas production and developing and executing financing and hedging strategies. Our ability to retain our officers and key employees is important to our continued success and growth. The unexpected loss of the services of one or more of these individuals could have a detrimental effect on our business. We do not maintain key person life insurance on any of our personnel. 
 
Lower oil and gas prices could negatively impact our ability to borrow. 
 
Our bank credit facility limits our borrowings to $500 million based on current bank commitments as of the date of this prospectus. The borrowing base, currently $600 million, is determined periodically at the discretion of a majority of the banks and is based in part on oil and gas prices. Additionally, some of our indentures contain covenants limiting our ability to incur indebtedness in addition to that incurred under our 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), 
 
11 

Table of Contents
which is determined using discounted future net revenues from proved oil and 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 all of our 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. 
 
Risks Related to the Exchange Offer and the New Notes 
 
If you do not properly tender your outstanding notes, you will continue to hold unregistered outstanding notes and your ability to transfer outstanding notes will be adversely affected. 
 
We will only issue new notes in exchange for outstanding notes that you timely and properly tender. Therefore, you should allow sufficient time to ensure timely delivery of the outstanding notes and you should carefully follow the instructions on how to tender your outstanding notes. Neither we nor the exchange agent is required to tell you of any defects or irregularities with respect to your tender of outstanding notes. 
 
If you do not exchange your outstanding notes for new notes pursuant to the exchange offer, the outstanding notes you hold will continue to be subject to the existing transfer restrictions. In general, you may not offer or sell the outstanding notes except under an exemption from, or in a transaction not subject to, the Securities Act and applicable state securities laws. We do not plan to register outstanding notes under the Securities Act unless our registration rights agreement with the initial purchasers of the outstanding notes requires us to do so. Further, if you continue to hold any outstanding notes after the exchange offer is consummated, you may have trouble selling them because there will be fewer such notes outstanding. 
 
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 Chesapeake 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. 	
 
12 

Table of Contents
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. 
 
Holders of the new notes, like holders of the outstanding notes, will be effectively subordinated to all of our and the subsidiary guarantors’ secured indebtedness and to all liabilities of our non-guarantor subsidiaries. 
 
Holders of our secured indebtedness, including the indebtedness under our revolving bank credit facility, have claims with respect to our assets constituting collateral for their indebtedness that are prior to your claims under the new notes. In the event of a default on the new 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 new notes. Accordingly, the secured indebtedness would effectively be senior to the new 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 some kinds of indebtedness without equally and ratably securing the new 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 new notes and the holders of other claims against us with respect to our other assets. 
 
In addition, the new notes are not guaranteed by all of our subsidiaries, and our non-guarantor subsidiaries are permitted to incur additional indebtedness under the indenture. As a result, holders of the new notes will be effectively subordinated to claims of third party creditors, including holders of indebtedness, and preferred shareholders of our non-guarantor subsidiaries. Claims of those other creditors, including trade creditors, secured creditors, authorities, holders of indebtedness or guarantees issued by this non-guarantor subsidiaries and preferred shareholders of our non-guarantor subsidiaries, will generally have priority as to the assets of the non-guarantor subsidiaries over our claims and equity interests. As a result, holders of our indebtedness, including the holders of the new notes, will be effectively subordinated to all those claims. As of June 14, 2004, our non-guarantor subsidiaries had no outstanding senior indebtedness.

EXCHANGE OFFER 
 
Purpose and Effect of the Exchange Offer 
 
In connection with the issuance of the outstanding notes, we entered into a registration rights agreement. Under the registration rights agreement, we agreed to: 
 
 	•	within 60 days after the original issuance of the outstanding notes on May 27, 2004, file a registration statement with the SEC with respect to a registered offer to exchange each outstanding note for a new note having terms substantially identical in all material respects to such note, except that the new note will not contain terms with respect to transfer restrictions; 	
 
 	•	use our best efforts to cause the registration statement to be declared effective under the Securities Act within 180 days after the original issuance of the outstanding notes; 	
 
 	•	promptly following the effectiveness of the registration statement, offer the new notes in exchange for surrender of the outstanding notes; and 	
 
 	•	keep the exchange offer open for not less than 30 days (or longer if required by applicable law) after the date notice of the exchange offer is mailed to the holders of the outstanding notes. 	
 
We have fulfilled the agreements described in the first two of the preceding bullet points and are now offering eligible holders of the outstanding notes the opportunity to exchange their outstanding notes for new notes registered under the Securities Act. Holders are eligible if they are not prohibited by any law or policy of the SEC from participating in this exchange offer. The new notes will be substantially identical to the outstanding notes except that the new notes will not contain terms with respect to transfer restrictions, registration rights or additional interest. 
 
Under limited circumstances, we agreed to use our best efforts to cause the SEC to declare effective a shelf registration statement for the resale of the outstanding notes. We also agreed to use our best efforts to keep the shelf registration statement effective for up to two years after its effective date. The circumstances include if: 
 
 	•	a change in law or in applicable interpretations thereof of the staff of the SEC does not permit us to effect the exchange offer; or 	
 
 	•	for any other reason the exchange offer is not consummated within 240 days from May 27, 2004, the date of the original issuance of the outstanding notes; or 	
 
 	•	any of the initial purchasers notify us following consummation of the exchange offer that outstanding notes held by it are not eligible to be exchanged for new notes in the exchange offer; or 	
 
 	•	certain holders are not eligible to participate in the exchange offer, or such holders do not receive freely tradeable securities on the date of the exchange. 	
 
We will pay additional cash interest on the applicable outstanding notes, subject to certain exceptions: 
 
 	•	if the exchange offer is not consummated on or before the 60th business day after this registration statement is declared effective, 	
 
 	•	if obligated to file a shelf registration statement, we fail to file the shelf registration statement with the SEC on or prior to the 30th day after the date on which the obligation to file a shelf registration statement arises, which we refer to as the shelf filing date, 	
 
 	•	if obligated to file a shelf registration statement due to the circumstances described in the first bullet point of the preceding paragraph, the shelf registration statement is not declared effective on or prior to the 180th day after the original issuance of the outstanding notes, 	
 
 	•	if we are obligated to file a shelf registration statement due to the circumstances described in the second, third or fourth bullet points of the preceding paragraph, the shelf registration statement is not declared effective on or prior to the 60th day after the shelf filing date, or 	
 
14 

Table of Contents
 	•	after this registration statement or the shelf registration statement, as the case may be, is declared effective, such registration statement thereafter ceases to be effective or usable (subject to certain exceptions) (each such event referred to in the preceding clauses being a “registration default”); 	
 
from and including the date on which any such registration default occurs to but excluding the date on which all registration defaults have been cured. 
 
The rate of the additional interest will be 0.5% per year for the first 90-day period immediately following the occurrence of a registration default, and such rate will increase by an additional 0.5% per year with respect to each subsequent 90-day period until all registration defaults have been cured, up to a maximum additional interest rate of 2.0% per year. We will pay such additional interest on regular interest payment dates. Such additional interest will be in addition to any other interest payable from time to time with respect to the outstanding notes and the new notes. 
 
Upon the effectiveness of this registration statement, the consummation of the exchange offer, the effectiveness of a shelf registration statement, or the effectiveness of a succeeding registration statement, as the case may be, the interest rate borne by the notes from the date of such effectiveness or consummation, as the case may be, will be reduced to the original interest rate. However, if after any such reduction in interest rate, a different registration default occurs, the interest rate may again be increased pursuant to the preceding paragraph. 
 
To exchange your outstanding notes for transferable new notes in the exchange offer, you will be required to make the following representations: 
 
 	•	any new notes will be acquired in the ordinary course of your business; 	
 
 	•	you have no arrangement or understanding with any person or entity to participate in the distribution of the new notes; 	
 
 	•	you are not engaged in and do not intend to engage in the distribution of the new notes; 	
 
 	•	if you are a broker-dealer that will receive new notes for your own account in exchange for outstanding notes, you acquired those notes as a result of market-making activities or other trading activities and you will deliver a prospectus, as required by law, in connection with any resale of such new notes; and 	
 
 	•	you are not our “affiliate,” as defined in Rule 405 of the Securities Act. 	
 
In addition, we may require you to provide information to be used in connection with the shelf registration statement to have your outstanding notes included in the shelf registration statement and benefit from the provisions regarding additional interest described in the preceding paragraphs. A holder who sells outstanding notes under the shelf registration statement generally will be required to be named as a selling securityholder in the related prospectus and to deliver a prospectus to purchasers. Such a holder will also be subject to the civil liability provisions under the Securities Act in connection with such sales and will be bound by the provisions of the registration rights agreement that are applicable to such a holder, including indemnification obligations. 
 
The description of the registration rights agreement contained in this section is a summary only. For more information, you should review the provisions of the registration rights agreement that we filed with the SEC as an exhibit to the registration statement of which this prospectus is a part. 
 
Resale of New Notes 
 
Based on no action letters of the SEC staff issued to third parties, we believe that new notes may be offered for resale, resold and otherwise transferred by you without further compliance with the registration and prospectus delivery provisions of the Securities Act if: 
 
 	•	you are not our “affiliate” within the meaning of Rule 405 under the Securities Act; 	
 
15 

Table of Contents
 	•	such new notes are acquired in the ordinary course of your business; and 	
 
 	•	you do not intend to participate in a distribution of the new notes. 	
 
The SEC, however, has not considered the exchange offer for the new notes in the context of a no action letter, and the SEC may not make a similar determination as in the no action letters issued to these third parties. 
 
If you tender in the exchange offer with the intention of participating in any manner in a distribution of the new notes, you 
 
 	•	cannot rely on such interpretations by the SEC staff; and 	
 
 	•	must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a secondary resale transaction. 	
 
Unless an exemption from registration is otherwise available, any security holder intending to distribute new notes should be covered by an effective registration statement under the Securities Act. This registration statement should contain the selling security holder’s information required by Item 507 of Regulation S-K under the Securities Act. This prospectus may be used for an offer to resell, resale or other retransfer of new notes only as specifically described in this prospectus. Only broker-dealers that acquired the outstanding notes as a result of market-making activities or other trading activities may participate in the exchange offer. Each broker-dealer that receives new notes for its own account in exchange for outstanding notes, where such outstanding notes were acquired by such broker-dealer as a result of market-making activities or other trading activities, must acknowledge by way of the letter of transmittal that it will deliver a prospectus in connection with any resale of the new notes. Please read the section captioned “Plan of Distribution” for more details regarding the transfer of new notes. 
 
Terms of the Exchange Offer 
 
Subject to the terms and conditions described in this prospectus and in the letter of transmittal, we will accept for exchange any outstanding notes properly tendered and not withdrawn prior to 5:00 p.m. New York City time on the expiration date. We will issue new notes in principal amount equal to the principal amount of outstanding notes surrendered under the exchange offer. Outstanding notes may be tendered only for new notes and only in integral multiples of $1,000. 
 
The exchange offer is not conditioned upon any minimum aggregate principal amount of outstanding notes being tendered for exchange. 
 
As of the date of this prospectus, $300,000,000 in aggregate principal amount of the outstanding notes are outstanding. This prospectus is being sent to DTC, the sole registered holder of the outstanding notes, and to all persons that we can identify as beneficial owners of the outstanding notes. There will be no fixed record date for determining registered holders of outstanding notes entitled to participate in the exchange offer. 
 
We intend to conduct the exchange offer in accordance with the provisions of the registration rights agreement, the applicable requirements of the Securities Act and the Securities Exchange Act of 1934 and the rules and regulations of the SEC. Outstanding notes whose holders do not tender for exchange in the exchange offer will remain outstanding and continue to accrue interest. These outstanding notes will be entitled to the rights and benefits such holders have under the indenture relating to the notes and the registration rights agreement. 
 
We will be deemed to have accepted for exchange properly tendered outstanding notes when we have given oral or written notice of the acceptance to the exchange agent and complied with the applicable provisions of the registration rights agreement. The exchange agent will act as agent for the tendering holders for the purposes of receiving the new notes from us.

Table of Contents
If you tender outstanding notes in the exchange offer, you will not be required to pay brokerage commissions or fees or, subject to the letter of transmittal, transfer taxes with respect to the exchange of outstanding notes. We will pay all charges and expenses, other than certain applicable taxes described below, in connecting with the exchange offer. It is important that you read the section labeled “—Fees and Expenses” for more details regarding fees and expenses incurred in the exchange offer. 
 
We will return any outstanding notes that we do not accept for exchange for any reason without expense to their tendering holder as promptly as practicable after the expiration or termination of the exchange offer. 
 
Expiration Date 
 
The exchange offer will expire at 5:00 p.m. New York City time on                      2004, unless, in our sole discretion, we extend it. 
 
Extensions, Delays in Acceptance, Termination or Amendment 
 
We expressly reserve the right, at any time or various times, to extend the period of time during which the exchange offer is open. We may delay acceptance of any outstanding notes by giving oral or written notice of such extension to their holders. During any such extensions, all outstanding notes previously tendered will remain subject to the exchange offer, and we may accept them for exchange. 
 
In order to extend the exchange offer, we will notify the exchange agent orally or in writing of any extension. We will notify the registered holders of outstanding notes of the extension no later than 9:00 a.m., New York City time, on the business day after the previously scheduled expiration date. 
 
If any of the conditions described below under “—Conditions to the Exchange Offer” have not been satisfied, we reserve the right, in our sole discretion 
 
 	•	to delay accepting for exchange any outstanding notes, 	
 
 	•	to extend the exchange offer, or 	
 
 	•	to terminate the exchange offer, 	
 
by giving oral or written notice of such delay, extension or termination to the exchange agent. Subject to the terms of the registration rights agreement, we also reserve the right to amend the terms of the exchange offer in any manner. 
 
Any such delay in acceptance, extension, termination or amendment will be followed as promptly as practicable by oral or written notice thereof to the registered holders of outstanding notes. If we amend the exchange offer in a manner that we determine to constitute a material change, we will promptly disclose such amendment by means of a prospectus supplement. The supplement will be distributed to the registered holders of the outstanding notes. Depending upon the significance of the amendment and the manner of disclosure to the registered holders, we will extend the exchange offer if the exchange offer would otherwise expire during such period. 
 
Conditions to the Exchange Offer 
 
We will not be required to accept for exchange, or exchange any new notes for, any outstanding notes if the exchange offer, or the making of any exchange by a holder of outstanding notes, would violate applicable law or any applicable interpretation of the staff of the SEC. Similarly, we may terminate the exchange offer as provided in this prospectus before accepting outstanding notes for exchange in the event of such a potential violation.

Table of Contents
In addition, we will not be obligated to accept for exchange the outstanding notes of any holder that has not made to us the representations described under “—Purpose and Effect of the Exchange Offer,” “—Procedures for Tendering” and “Plan of Distribution” and such other representations as may be reasonably necessary under applicable SEC rules, regulations or interpretations to allow us to use an appropriate form to register the new notes under the Securities Act. 
 
We expressly reserve the right to amend or terminate the exchange offer, and to reject for exchange any outstanding notes not previously accepted for exchange, upon the occurrence of any of the conditions to the exchange offer specified above. We will give oral or written notice of any extension, amendment, non-acceptance or termination to the holders of the outstanding notes as promptly as practicable. 
 
These conditions are for our sole benefit, and we may assert them or waive them in whole or in part at any time or at various times in our sole discretion. If we fail at any time to exercise any of these rights, this failure will not mean that we have waived our rights. Each such right will be deemed an ongoing right that we may assert at any time or at various times. 
 
In addition, we will not accept for exchange any outstanding notes tendered, and will not issue new notes in exchange for any such outstanding notes, if at such time any stop order has been threatened or is in effect with respect to the registration statement of which this prospectus constitutes a part or the qualification of the indenture relating to the notes under the Trust Indenture Act of 1939. 
 
Procedures for Tendering 
 
In order to participate in the exchange offer, you must properly tender your outstanding notes to the exchange agent as described below. It is your responsibility to properly tender your notes. We have the right to waive any defects. However, we are not required to waive defects and are not required to notify you of defects in your exchange. 
 
If you have any questions or need help in exchanging your notes, please call the exchange agent whose address and phone number are described in the section of the prospectus entitled “Where You Can Find More Information.” 
 
All of the outstanding notes were issued in book-entry form, and all of the outstanding notes are currently represented by global certificates held for the account of DTC. We have confirmed with DTC that the outstanding notes may be tendered using the Automated Tender Offer Program (“ATOP”) instituted by DTC. The exchange agent will establish an account with DTC for purposes of the exchange offer promptly after the commencement of the exchange offer and DTC participants may electronically transmit their acceptance of the exchange offer by causing DTC to transfer their outstanding notes to the exchange agent using the ATOP procedures. In connection with the transfer, DTC will send an “agent’s message” to the exchange agent. The agent’s message will state that DTC has received instructions from the participant to tender outstanding notes and that the participant agrees to be bound by the terms of the letter of transmittal. 
 
By using the ATOP procedures to exchange outstanding notes, you will not be required to deliver a letter of transmittal to the exchange agent. However, you will be bound by its terms just as if you had signed it. 
 
There is no procedure for guaranteed late delivery of the notes. 
 
Determinations Under the Exchange Offer 
 
We will determine in our sole discretion all questions as to the validity, form, eligibility, time of receipt, acceptance of tendered outstanding notes and withdrawal of tendered outstanding notes. Our determination will be final and binding. We reserve the absolute right to reject any outstanding notes not properly tendered or any 
 
18 

Table of Contents
outstanding notes our acceptance of which would, in the opinion of our counsel, be unlawful. We also reserve the right to waive any defect, irregularities or conditions of tender as to particular outstanding notes. Our interpretation of the terms and conditions of the exchange offer, including the instructions in the letter of transmittal, will be final and binding on all parties. Unless waived, all defects or irregularities in connection with tenders of outstanding notes must be cured within such time as we shall determine. Although we intend to notify holders of defects or irregularities with respect to tenders of outstanding notes, neither we, the exchange agent nor any other person will incur any liability for failure to give such notification. Tenders of outstanding notes will not be deemed made until such defects or irregularities have been cured or waived. Any outstanding notes received by the exchange agent that are not properly tendered and as to which the defects or irregularities have not been cured or waived will be returned to the tendering holder as soon as practicable following the expiration date. 
 
When We Will Issue New Notes 
 
In all cases, we will issue new notes for outstanding notes that we have accepted for exchange under the exchange offer only after the exchange agent receives, prior to 5:00 p.m., New York City time, on the expiration date, 
 
 	•	a book-entry confirmation of such outstanding notes into the exchange agent’s account at DTC; and 	
 
 	•	a properly transmitted agent’s message. 	
 
Return of Outstanding Notes Not Accepted or Exchanged 
 
If we do not accept any tendered outstanding notes for exchange or if outstanding notes are submitted for a greater principal amount than the holder desires to exchange, the unaccepted or non-exchanged outstanding notes will be returned without expense to their tendering holder. Such non-exchanged outstanding notes will be credited to an account maintained with DTC. These actions will occur as promptly as practicable after the expiration or termination of the exchange offer. 
 
Your Representations to Us 
 
By agreeing to be bound by the letter of transmittal, you will represent to us that, among other things: 
 
 	•	any new notes that you receive will be acquired in the ordinary course of your business; 	
 
 	•	you have no arrangement or understanding with any person or entity to participate in the distribution of the new notes; 	
 
 	•	you are not engaged in and do not intend to engage in the distribution of the new notes; 	
 
 	•	if you are a broker-dealer that will receive new notes for your own account in exchange for outstanding notes, you acquired those notes as a result of market-making activities or other trading activities and you will deliver a prospectus, as required by law, in connection with any resale of such new notes; and 	
 
 	•	you are not our “affiliate,” as defined in Rule 405 of the Securities Act. 	
 
Withdrawal of Tenders 
 
Except as otherwise provided in this prospectus, you may withdraw your tender at any time prior to 5:00 p.m. New York City time on the expiration date. For a withdrawal to be effective you must comply with the appropriate procedures of DTC’s ATOP system. Any notice of withdrawal must specify the name and number of the account at DTC to be credited with withdrawn outstanding notes and otherwise comply with the procedures of DTC. 
 
We will determine all questions as to the validity, form, eligibility and time of receipt of notice of withdrawal. Our determination shall be final and binding on all parties. We will deem any outstanding notes so withdrawn not to have been validly tendered for exchange for purposes of the exchange offer. 
 
19 

Table of Contents
Any outstanding notes that have been tendered for exchange but that are not exchanged for any reason will be credited to an account maintained with DTC for the outstanding notes. This return or crediting will take place as soon as practicable after withdrawal, rejection of tender or termination of the exchange offer. You may retender properly withdrawn outstanding notes by following the procedures described under “—Procedures for Tendering” above at any time on or prior to the expiration date. 
 
Fees and Expenses 
 
We will bear the expenses of soliciting tenders. The principal solicitation is being made by mail; however, we may make additional solicitation by telegraph, telephone or in person by our officers and regular employees and those of our affiliates. 
 
We have not retained any dealer-manager in connection with the exchange offer and will not make any payments to broker-dealers or others soliciting acceptances of the exchange offer. We will, however, pay the exchange agent reasonable and customary fees for its services and reimburse it for its related reasonable out-of-pocket expenses. 
 
We will pay the cash expenses to be incurred in connection with the exchange offer. They include: 
 
 	•	SEC registration fees; 	
 
 	•	fees and expenses of the exchange agent and trustee; 	
 
 	•	accounting and legal fees and printing costs; and 	
 
 	•	related fees and expenses. 	
 
Transfer Taxes 
 
We will pay all transfer taxes, if any, applicable to the exchange of outstanding notes under the exchange offer. The tendering holder, however, will be required to pay any transfer taxes, whether imposed on the registered holder or any other person, if a transfer tax is imposed for any reason other than the exchange of outstanding notes under the exchange offer. 
 
Consequences of Failure to Exchange 
 
If you do not exchange new notes for your outstanding notes under the exchange offer, you will remain subject to the existing restrictions on transfer of the outstanding notes. In general, you may not offer or sell the outstanding notes unless they are registered under the Securities Act, or if the offer or sale is exempt from the registration under the Securities Act and applicable state securities laws. Except as required by the registration rights agreement, we do not intend to register resales of the outstanding notes under the Securities Act. 
 
Accounting Treatment 
 
We will record the new notes in our accounting records at the same carrying value as the outstanding notes. This carrying value is the aggregate principal amount of the outstanding notes less any bond discount, as reflected in our accounting records on the date of exchange. Accordingly, we will not recognize any gain or loss for accounting purposes in connection with the exchange offer. 
 
Other 
 
Participation in the exchange offer is voluntary, and you should carefully consider whether to accept. You are urged to consult your financial and tax advisors in making your own decision on what action to take. 
 
We may in the future seek to acquire untendered outstanding notes in open market or privately negotiated transactions, through subsequent exchange offers or otherwise. We have no present plans to acquire any outstanding notes that are not tendered in the exchange offer or to file a registration statement to permit resales of any untendered outstanding notes.

USE OF PROCEEDS 
 
The exchange offer is intended to satisfy our obligations under the registration rights agreement. We will not receive any cash proceeds from the issuance of the new notes in the exchange offer. In consideration for issuing the new notes as contemplated by this prospectus, we will receive outstanding notes in a like principal amount. The form and terms of the new notes are identical in all respects to the form and terms of the outstanding notes, except the new notes do not include certain transfer restrictions. Outstanding notes surrendered in exchange for the new notes will be retired and cancelled and will not be reissued. Accordingly, the issuance of the new notes will not result in any change in our outstanding indebtedness.

Table of Contents
DESCRIPTION OF THE NEW NOTES 
 
The new notes will be issued, and the outstanding notes were issued, pursuant to an indenture dated as of May 27, 2004 (the “Indenture”) among the Company, as issuer, the Subsidiary Guarantors, as guarantors, and The Bank of New York, as trustee (the “Trustee”). The terms of the new notes include those stated in the Indenture and those made part of the Indenture by the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). The definitions of certain capitalized terms used in the following summary are set forth below under “—Certain Definitions.” 
 
The following description is only a summary of the material provisions of the Indenture. It does not restate that agreement in its entirety. The Company urges Holders to read the Indenture because it, and not this description, defines the rights of Holders of these notes. The Company has filed the Indenture as an exhibit to the registration statement which includes this prospectus. 
 
If the exchange offer contemplated by this prospectus (the “Exchange Offer”) is consummated, Holders of outstanding notes who do not exchange those notes for new notes in the Exchange Offer will vote together with Holders of new notes for all relevant purposes under the Indenture. In that regard, the Indenture requires that certain actions by the Holders thereunder (including acceleration following an Event of Default) must be taken, and certain rights must be exercised, by specified minimum percentages of the aggregate principal amount of the outstanding securities issued under the Indenture. In determining whether Holders of the requisite percentage in principal amount have given any notice, consent or waiver or taken any other action permitted under the Indenture, any outstanding notes that remain outstanding after the Exchange Offer will be aggregated with the new notes, and the Holders of such outstanding notes and the new notes will vote together as a single series for all such purposes. Accordingly, all references herein to specified percentages in aggregate principal amount of the notes outstanding shall be deemed to mean, at any time after the Exchange Offer is consummated, such percentages in aggregate principal amount of the outstanding notes and the new notes then outstanding. 
 
Brief Description of the Notes 
 
The Notes: 
 
 	•	are unsecured senior indebtedness of the Company; 	
 
 	•	are unlimited in aggregate principal amount, of which $300,000,000 are currently outstanding; 	
 
 	•	are senior in right of payment to all future Subordinated Indebtedness of the Company; and 	
 
 	•	rank equally in right of payment with all existing and future Senior Indebtedness. 	
 
The new notes will be issued, and the outstanding notes were issued, only in registered form, without coupons, in denominations of $1,000 and integral multiples thereof. 
 
Any outstanding notes that remain outstanding after the completion of the Exchange Offer, together with the new notes issued in connection with the Exchange Offer and any other notes issued under the indenture then outstanding, will be treated as a single class of securities under the Indenture. 
 
The Company may issue the notes from time to time with an unlimited maximum aggregate principal amount, of which $300 million were issued on May 27, 2004. Any notes issued in the future (“Add On Notes”) will be subject to the debt incurrence covenant described in the first paragraph of “—Certain Covenants—Limitations on Incurrence of Additional Indebtedness.” Any Add On Notes that are actually issued will be treated as issued and outstanding Notes (as the same class as the new notes) for all purposes of the Indenture and this “Description of the New Notes,” unless the context indicates otherwise. Each Note will mature on June 15, 2014 and will bear interest at the rate of interest per annum indicated on the cover page of this prospectus. 
 
23 

Table of Contents
Interest on the new notes will accrue from May 27, 2004, and will be payable semiannually in arrears on June 15 and December 15 of each year, commencing December 15, 2004. We will make each interest payment to the holders of record of the Notes at the close of business on the June 1 or December 1 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 future Senior Indebtedness of the Company and rank senior in right of payment to all future Subordinated Indebtedness of the Company. 
 
Guarantees 
 
All the existing subsidiaries of the Company, other than Chesapeake Energy Marketing, Inc., Mayfield Processing, L.L.C. and MidCon Compression L.P., 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 Restricted Subsidiary after the Issue Date will guarantee the payment of the Notes. 
 
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 Exchange Offer and the New 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 Chesapeake 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, 
 
(2) immediately after such transaction, no Default or Event of Default exists, 
 
(3) such Subsidiary Guarantor or the Person formed by or surviving any such consolidation or merger will have Consolidated Tangible Net Worth immediately after the transaction equal to or greater than the Consolidated Tangible Net Worth of such Subsidiary Guarantor immediately preceding the transaction, and 
 
(4) the Company will, at the time of such transaction after giving pro forma effect thereto as if such transaction had occurred at the beginning of the Reference Period, be permitted to incur at least $1.00 of additional Indebtedness (other than Permitted Indebtedness) pursuant to the “—Limitation on Incurrence of Additional Indebtedness” covenant. 
 
The preceding does not prohibit a merger between Subsidiary Guarantors or a merger between the Company and a Subsidiary Guarantor. 
 
24 

Table of Contents
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, or a Subsidiary Guarantor otherwise ceases to be a Subsidiary Guarantor, then the Person acquiring the assets (in the event of a sale or other disposition, by way of such a merger, consolidation or otherwise, of all or substantially all of the assets of such Subsidiary Guarantor) or such Subsidiary Guarantor (in any other event) will be released and relieved of any obligations under its Guarantee. 
 
Ranking 
 
Senior Indebtedness versus Notes. The Indebtedness evidenced by the Notes and the Guarantees is unsecured and ranks 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, 2004, Senior Indebtedness of the Company and the Subsidiary Guarantors was approximately $2.09 billion, none of which was secured indebtedness. 
 
The Notes are unsecured obligations of the Company. Secured debt and other secured obligations of the Company and the Subsidiary Guarantors (including obligations with respect to our current bank credit facility) is 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 such 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 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 are effectively subordinated to creditors (including trade creditors) and preferred stockholders, if any, of the Company’s subsidiaries that are not Subsidiary Guarantors. All of the Company’s subsidiaries, other than Chesapeake Energy Marketing, Inc., Mayfield Processing, L.L.C. and MidCon Compression L.P., will be Subsidiary Guarantors. As of the date of this prospectus, the non-guarantor subsidiaries have no outstanding indebtedness. 
 
Although the Indenture limits the incurrence of Indebtedness (including some types of preferred stock) of the Restricted Subsidiaries, such limitations are subject to a number of significant qualifications. In addition, the Indenture does not impose any limitations on the incurrence by the Restricted Subsidiaries of liabilities that are not considered Indebtedness under the Indenture. Please read “— Certain Covenants — Limitation on Incurrence of Additional Indebtedness.” Moreover, the Indenture does not impose any limitation on the incurrence by any Unrestricted Subsidiary of Indebtedness (including preferred stock). 
 
Optional Redemption 
 
At any time on or after June 15, 2009, the Company may, at its option, redeem all or any portion of the Notes at the applicable redemption prices (expressed as percentages of the principal amount of the Notes) described below, plus, in each case, accrued but unpaid interest thereon to the applicable redemption date if the Notes are redeemed during the twelve-month period beginning on June 15 of the years set forth below: 

Year

Table of Contents
Notwithstanding the foregoing, at any time prior to June 15, 2009, 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. In addition, in the event the Company consummates one or more Equity Offerings on or prior to June 15, 2007, the Company, at its option, may redeem up to 35% of the aggregate principal amount of the Notes (which includes Add On Notes, if any) issued under the Indenture with all or a portion of the aggregate net proceeds received by the Company from such Equity Offerings at a redemption price of 107.50%, plus accrued and unpaid interest thereon to the redemption date; provided, however, that 
 
 	•	the date of such redemption occurs within the 90-day period after the Equity Offering in respect of which such redemption is made and 	
 
 	•	following each such redemption, at least 65% of the aggregate principal amount of the Notes (which includes Add On Notes, if any) issued under the Indenture remain outstanding. 	
 
Change of Control 
 
The Indenture provides that, following the occurrence of any Change of Control, the Company must offer to purchase all outstanding Notes at a purchase price equal to 101% of the aggregate principal amount of the Notes, plus accrued and unpaid interest to the date of purchase. 
 
Within 15 days after any Change of Control, the Company will mail or cause to be mailed to all Holders on the date of the Change of Control a Notice (the “Change of Control Notice”) of the occurrence of such Change of Control and of the Holders’ rights arising as a result thereof. The Change of Control Notice shall state, among other things: 
 
(1) that the change of control offer is being made pursuant to this covenant; 
 
(2) the purchase price and the change of control payment date; 
 
(3) that any Note not tendered will continue to accrue interest; 
 
(4) that any Note accepted for payment pursuant to the change of control offer shall cease to accrue interest on the change of control payment date; and 
 
(5) the instructions, consistent with the covenant described hereunder, that a Holder must follow in order to have such Holder’s Notes purchased. 
 
The change of control offer will be deemed to have commenced upon mailing of a notice pursuant to the Indenture and will terminate 20 business days after its commencement, unless a longer offering period is required by law. Promptly after the termination of the change of control offer, the Company will purchase and mail or deliver payment for all Notes tendered in response to the change of control offer. 
 
On the change of control payment date, the Company will, to the extent lawful: 
 
 	•	accept for payment Notes or portions thereof tendered pursuant to the change of control offer, 	
 
 	•	deposit with the paying agent an amount equal to the change of control payment in respect of all Notes or portions thereof so tendered and 	
 
 	•	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 change of control offer.

Table of Contents
The Change of Control purchase feature of the Notes may in certain circumstances make more difficult or discourage a sale or takeover of the Company. The change of control purchase feature is a result of negotiations between the Company and the initial purchasers. The Company has no present intention to engage in a transaction involving a Change of Control, although it is possible that it could decide to do so in the future. Subject to the limitations discussed below, the Company could, in the future, enter into certain transactions, including acquisitions, refinancings or other recapitalizations, that would not constitute a Change of Control under the Indenture, but that could increase the amount of indebtedness outstanding at such time or otherwise affect the Company’s capital structure or credit ratings. Restrictions on the Company’s ability to incur additional Indebtedness are contained in the covenants described under “—Certain Covenants—Limitation on Incurrence of Additional Indebtedness,” “—Limitation on Liens” and “—Limitation on Sale/ Leaseback Transactions.” Under the Indenture, such restrictions can only be waived with the consent of the Holders of a majority in principal amount of the Notes then outstanding. Except for the limitations contained in such covenants, however, the Indenture does not contain any covenants or provisions that may afford Holders of the Notes protection in the event of a highly leveraged transaction. 
 
Future indebtedness that the Company may incur may contain prohibitions on the occurrence of certain events that would constitute a Change of Control or require the repurchase of such indebtedness upon a Change of Control. Moreover, the exercise by the Holders of their right to require the Company to repurchase the Notes could cause a default under such indebtedness, even if the Change of Control itself does not, due to the financial effect of such repurchase on the Company. Finally, the Company’s ability to pay cash to the Holders of Notes following the occurrence of a Change of Control may be limited by the Company’s then existing financial resources. There can be no assurance that sufficient funds will be available when necessary to make any required repurchases. 
 
The provisions under the Indenture relative to the Company’s obligation to make an offer to repurchase the Notes as a result of a Change of Control may be waived or modified with the written consent of the Holders of a majority in principal amount of the Notes. 
 
Certain Covenants 
 
The following restrictive covenants are applicable to the Company and its Restricted Subsidiaries. 
 
Limitation on Incurrence of Additional Indebtedness. The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, issue, incur, assume, guarantee, become liable, contingently or otherwise, with respect to or otherwise become responsible for the payment of (collectively, “incur”) any Indebtedness; provided, however, that if no Default or Event of Default shall have occurred and be continuing at the time or as a consequence of the incurrence of such Indebtedness, the Company or its Restricted Subsidiaries may incur Indebtedness if, on a pro forma basis, after giving effect to such incurrence and the application of the proceeds therefrom, either of the following tests shall have been satisfied: (1) the Adjusted Consolidated EBITDA Coverage Ratio would have been at least 2.25 to 1.0 or (2) Adjusted Consolidated Net Tangible Assets would have been greater than 200% of Indebtedness of the Company and its Restricted Subsidiaries. 
 
Notwithstanding the preceding, if no Default or Event of Default shall have occurred and be continuing at the time or as a consequence of the incurrence of such Indebtedness, the Company and its Restricted Subsidiaries may incur Permitted Indebtedness. For purposes of determining compliance with this covenant: 
 
(1) in the event that an item of proposed Indebtedness meets the criteria of more than one of the categories of Permitted Indebtedness as of the date of incurrence thereof or is entitled to be incurred pursuant to the first paragraph of this covenant as of the date of incurrence thereof, the Company shall, in its sole discretion, classify (or later classify in whole or in part, in its sole discretion) such item of Indebtedness in any manner that complies with this covenant; and 
 
(2) for purposes of determining compliance with any dollar-denominated restriction on the incurrence of Indebtedness denominated in a foreign currency, the dollar-equivalent principal amount of such Indebtedness incurred pursuant thereto shall be calculated based on the relevant currency. 
 
27 

Table of Contents
Accrual of interest or dividends, the accretion of accreted value or liquidation preference and the payment of interest or dividends in the form of additional Indebtedness will not be deemed to be an incurrence of Indebtedness for purposes of this covenant. 
 
Any Indebtedness of a Person existing at the time such Person becomes a Restricted Subsidiary (whether by merger, consolidation, acquisition or otherwise) shall be deemed to be incurred by such Restricted Subsidiary at the time it becomes a Restricted Subsidiary.

(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 $10.0 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; 
 
(5) default in the performance, or breach of, the covenants set forth in the covenants captioned “Limitation on Restricted Payments” and “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 (other than a Non-Recourse Subsidiary or an Unrestricted Subsidiary, provided that neither the Company nor any Restricted Subsidiary is liable, directly or indirectly, for such judgment or order) in an aggregate amount in excess of $10.0 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 (other than a Non-Recourse Subsidiary or an Unrestricted Subsidiary). 
 
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 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 (other than a Non-Recourse Subsidiary or an Unrestricted Subsidiary) 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, 
 
48 

Table of Contents
(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 
 
Modifications 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, supplement or waiver; 
 
(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;

(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 
 
(9) waive a continuing Default or Event of Default in the payment of principal of, premium, if any, or interest on the Notes. 
 
Modifications 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. 
 
49 

Table of Contents
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 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; 
 
50 

Table of Contents
(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 is the Trustee under the Indenture. The Bank of New York also serves as trustee for our 8.375% Senior Notes due 2008, our 8.125% Senior Notes due 2011, our 9% Senior Notes due 2012, our 7.5% Senior Notes due 2013, our 7.75% Senior Notes due 2015 and our 6.875% Senior Notes due 2016. 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. Its address is 101 Barclay Street, 8th Floor, New York, New York 10286. The Company has also appointed the Trustee as the initial registrar and paying agent under the Indenture. 
 
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. 
 
51 

Table of Contents
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 initial purchasers), 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 new notes represented by such global securities to the accounts of participants exchanging outstanding 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 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 
 
52 

Table of Contents
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.

FEDERAL INCOME TAX CONSIDERATIONS 
 
Federal Income Tax Considerations of the Exchange of Outstanding Notes for New Notes 
 
The following discussion is a summary of certain federal income tax considerations relevant to the exchange of outstanding notes for new notes, but does not purport to be a complete analysis of all potential tax effects. The discussion is based upon the Internal Revenue Code of 1986, as amended, Treasury Regulations, Internal Revenue Service rulings and pronouncements and judicial decisions now in effect, all of which may be subject to change at any time by legislative, judicial or administrative action. These changes may be applied retroactively in a manner that could adversely affect a holder of new notes. The description does not consider the effect of any applicable foreign, state, local or other tax laws or estate or gift tax considerations. 
 
We believe that the exchange of outstanding notes for new notes should not be an exchange or otherwise a taxable event to a holder for United States federal income tax purposes. Accordingly, a holder should have the same adjusted issue price, adjusted basis and holding period in the new notes as it had in the outstanding notes immediately before the exchange. 
 
PLAN OF DISTRIBUTION 
 
Based on interpretations by the staff of the SEC in no action letters issued to third parties, we believe that you may transfer new notes issued under the exchange offer in exchange for the outstanding notes if: 
 
 	•	you acquire the new notes in the ordinary course of your business; and 	
 
 	•	you are not engaged in, and do not intend to engage in, and have no arrangement or understanding with any person to participate in, a distribution of such new notes. 	
 
You may not participate in the exchange offer if you are: 
 
 	•	our “affiliate” within the meaning of Rule 405 under the Securities Act; or 	
 
 	•	a broker-dealer that acquired outstanding notes directly from us. 	
 
Each broker-dealer that receives new notes for its own account pursuant to the exchange offer must acknowledge that it will deliver a prospectus in connection with any resale of such new notes. To date, the staff of the SEC has taken the position that broker-dealers may fulfill their prospectus delivery requirements with respect to transactions involving an exchange of securities such as this exchange offer, other than a resale of an unsold allotment from the original sale of the outstanding notes, with the prospectus contained in this registration statement. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of new notes received in exchange for outstanding notes where such outstanding notes were acquired as a result of market-making activities or other trading activities. We have agreed that, for a period of up to 180 days after the effective date of this registration statement, we will make this prospectus, as amended or supplemented, available to any broker-dealer for use in connection with any such resale. In addition, until such date, all dealers effecting transactions in new notes may be required to deliver a prospectus. 
 
If you wish to exchange new notes for your outstanding notes in the exchange offer, you will be required to make representations to us as described in “Exchange Offer—Purpose and Effect of the Exchange Offer” and “—Procedures for Tendering—Your Representations to Us” in this prospectus. As indicated in the letter of transmittal, you will be deemed to have made these representations by tendering your outstanding notes in the exchange offer. In addition, if you are a broker-dealer who receives new notes for your own account in exchange for outstanding notes that were acquired by you as a result of market-making activities or other trading activities, you will be required to acknowledge, in the same manner, that you will deliver a prospectus in connection with any resale by you of such new notes. 
 
54 

Table of Contents
We will not receive any proceeds from any sale of new notes by broker-dealers. New notes received by broker-dealers for their own account pursuant to the exchange offer may be sold from time to time in one or more transactions in the over-the-counter market: 
 
 	•	in negotiated transactions; 	
 
 	•	through the writing of options on the new notes or a combination of such methods of resale; 	
 
 	•	at market prices prevailing at the time of resale; and 	
 
 	•	at prices related to such prevailing market prices or negotiated prices. 	
 
Any such resale may be made directly to purchasers or to or through brokers or dealers who may receive compensation in the form of commissions or concessions from any such broker-dealer or the purchasers of any such new notes. Any broker-dealer that resells new notes that were received by it for its own account pursuant to the exchange offer and any broker or dealer that participates in a distribution of such new notes may be deemed to be an “underwriter” within the meaning of the Securities Act. The letter of transmittal states that by acknowledging that it will deliver and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act. 
 
For a period of 180 days after the effective date of this registration statement, we will promptly send additional copies of this prospectus and any amendment or supplement to this prospectus to any broker-dealer that requests such documents in the letter of transmittal. We have agreed to pay all expenses incident to the exchange offer (including the expenses of one counsel for the holders of the outstanding notes) other than commissions or concessions of any broker-dealers and will indemnify the holders of the outstanding notes (including any broker-dealers) against certain liabilities, including liabilities under the Securities Act.

The validity of the new notes offered in this exchange offer will be passed upon for us by Vinson & Elkins L.L.P. in reliance on the opinion of Commercial Law Group P.C. with respect to matters of Oklahoma law.

The undersigned hereby acknowledges receipt and review of the Prospectus, dated                      (the “Prospectus”), of Chesapeake Energy Corporation, an Oklahoma corporation (the “Company”), and this Letter of Transmittal (the “Letter of Transmittal”), which together describe the Company’s offer (the “Exchange Offer”) to exchange its 7.50% Senior Notes due 2014 (the “New Notes”) that have been registered under the Securities Act of 1933, as amended (the “Securities Act”), for a like principal amount of its issued and outstanding 7.50% Senior Notes due 2014 (the “Outstanding Notes”). Capitalized terms used but not defined herein have the respective meaning given to them in the Prospectus. 
 
The Company reserves the right, at any time or from time to time, to extend the Exchange Offer at its discretion, in which event the term “Expiration Date” shall mean the latest date to which the Exchange Offer is extended. The Company shall notify the Exchange Agent and each registered holder of the Outstanding Notes of any extension by oral or written notice prior to 9:00 a.m., New York City time, on the next business day after the previously scheduled Expiration Date.

Tender of Outstanding Notes is to be made according to the Automated Tender Offer Program (“ATOP”) of the Depository Trust Company (“DTC”) pursuant to the procedures set forth in the prospectus under the caption “The Exchange Offer—Procedures for Tendering.” DTC participants that are accepting the Exchange Offer must transmit their acceptance to DTC, which will verify the acceptance and execute a book-entry delivery to the Exchange Agent’s DTC account. DTC will then send a computer generated message known as an “agent’s message” to the exchange agent for its acceptance. For you to validly tender your Outstanding Notes in the Exchange Offer, the Exchange Agent must receive, prior to the Expiration Date, an agent’s message under the ATOP procedures that confirms that: 
 
 	•	DTC has received your instructions to tender your Outstanding Notes; and 	
 
 	•	You agree to be bound by the terms of this Letter of Transmittal. 	
 
By using the ATOP procedures to tender outstanding notes, you will not be required to deliver this Letter of Transmittal to the Exchange Agent. However, you will be bound by its terms, and you will be deemed to have made the acknowledgments and the representations and warranties it contains, just as if you had signed it.

PART II 
 
INFORMATION NOT REQUIRED IN PROSPECTUS 
 
Item 20. Indemnification Of Officers And Directors 
 
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. 
 
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 22. Undertakings 
 
Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of any Registrant, we have been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by any Registrant of expenses incurred or paid by a director, officer or controlling person of such 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, such Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue. 
 
Each 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: 
 
(a) To include any prospectus required by section 10(a)(3) of the Securities Act of 1933; 
 
(b) 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; 
 
(c) 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; and 
 
(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 the registrants annual report pursuant to section 13(a) or section 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) To respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11, or 13 of this Form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. 
 
This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request. 
 
(6) To supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in this Registration Statement when it became effective.

INDENTURE, dated as of May 27, 2004, among CHESAPEAKE ENERGY CORPORATION, an Oklahoma corporation (the “Company”), the SUBSIDIARY GUARANTORS listed as signatories hereto and The Bank of New York, a New York corporation, as Trustee. 
 
Each party agrees as follows for the benefit of the other parties and for the equal and ratable benefit of the holders of the Company’s 7.50% Senior Notes due 2014: 
 
ARTICLE ONE 
 
DEFINITIONS AND INCORPORATION BY REFERENCE 
 
SECTION 1.01. Definitions. 
 
“Additional Securities” means, subject to the Company’s compliance with Section 4.09(a), 7.50% Senior Notes due 2014 issued from time to time after the Issue Date under the terms of this Indenture (other than pursuant to Section 2.06, 2.07, 2.09 or 3.06 of this Indenture and other than Exchange Securities or Private Exchange Securities issued pursuant to an exchange offer for other Securities outstanding under this Indenture). 
 
“Adjusted Consolidated EBITDA” means the Consolidated Net Income of the Company and its Restricted Subsidiaries for the Reference Period, (a) increased (to the extent deducted in determining Consolidated Net Income) by the sum, without duplication, of: (i) all income and state franchise taxes of the Company and its Restricted Subsidiaries paid or accrued according to GAAP for such period (other than income taxes attributable to extraordinary, unusual or non-recurring gains or losses); (ii) all interest expense of the Company and its Restricted Subsidiaries paid or accrued in accordance with GAAP for such period (including amortization of original issue discount or premium); (iii) depreciation and depletion of the Company and its Restricted Subsidiaries; (iv) amortization of the Company and its Restricted Subsidiaries including, without limitation, amortization of capitalized debt issuance costs; (v) any loss realized in accordance with GAAP upon the sale or other disposition of any property, plant or equipment of the Company or its Restricted Subsidiaries (including pursuant to any Sale/Leaseback Transaction) which is not sold or otherwise disposed of in the ordinary course of business and any loss realized in accordance with GAAP upon the sale or other disposition of any Capital Stock of any Person; (vi) any loss realized in accordance with GAAP from currency exchange transactions not in the ordinary course of business consistent with past practice; (vii) any loss net of income taxes realized in accordance with GAAP attributable to extraordinary items; (viii) any charges associated solely with the prepayment of any Indebtedness; and (ix) any other non-cash charges to the extent deducted from Consolidated Net Income and (b) decreased (to the extent included in determining Consolidated Net Income) by the sum of (i) the amount of deferred revenues that are amortized during the Reference Period and are attributable to reserves that are subject to Volumetric Production Payments and (ii) amounts recorded in accordance with GAAP as repayments of principal and interest pursuant to Dollar-Denominated Production Payments. 

“Adjusted Consolidated EBITDA Coverage Ratio” means, for any Reference Period, the ratio on a pro forma basis of (a) Adjusted Consolidated EBITDA for the Reference Period to (b) Adjusted Consolidated Interest Expense for such Reference Period; provided, that, in calculating Adjusted Consolidated EBITDA and Adjusted Consolidated Interest Expense (i) acquisitions which occurred during the Reference Period or subsequent to the Reference Period and on or prior to the date of the transaction giving rise to the need to calculate the Adjusted Consolidated EBITDA Coverage Ratio (the “Transaction Date”) shall be assumed to have occurred on the first day of the Reference Period, (ii) the incurrence of any Indebtedness (including the issuance of the Securities) or issuance of any Disqualified Stock during the Reference Period or subsequent to the Reference Period and on or prior to the Transaction Date shall be assumed to have occurred on the first day of such Reference Period, (iii) any Indebtedness that had been outstanding during the Reference Period that has been repaid on or prior to the Transaction Date shall be assumed to have been repaid as of the first day of such Reference Period, (iv) the Adjusted Consolidated Interest Expense attributable to interest on any Indebtedness or dividends on any Disqualified Stock bearing a floating interest (or dividend) rate shall be computed on a pro forma basis as if the rate in effect on the Transaction Date were the average rate in effect during the entire Reference Period and (v) in determining the amount of Indebtedness pursuant to Section 4.09, the incurrence of Indebtedness or issuance of Disqualified Stock giving rise to the need to calculate the Adjusted Consolidated EBITDA Coverage Ratio and, to the extent the net proceeds from the incurrence or issuance thereof are used to retire Indebtedness, the application of the proceeds therefrom shall be assumed to have occurred on the first day of the Reference Period. 
 
“Adjusted Consolidated Interest Expense” means, with respect to the Company and its Restricted Subsidiaries, for the Reference Period, the aggregate amount (without duplication) of (a) interest expensed in accordance with GAAP (including, in accordance with the following sentence, interest attributable to Capitalized Lease Obligations, but excluding interest attributable to Dollar-Denominated Production Payments and amortization of deferred debt expense) during such period in respect of all Indebtedness of the Company and its Restricted Subsidiaries (including (i) amortization of original issue discount or premium on any Indebtedness (other than with respect to the Existing Notes and the Securities), (ii) the interest portion of all deferred payment obligations, calculated in accordance with GAAP, and (iii) all commissions, discounts and other fees and charges owed with respect to bankers’ acceptance financings and currency and interest rate swap arrangements, in each case to the extent attributable to such period), and (b) dividend requirements of the Company and its Restricted Subsidiaries with respect to any Preferred Stock dividends (whether in cash or otherwise (except dividends paid solely in shares of Qualified Stock)) paid (other than to the Company or any of its Restricted Subsidiaries), declared, accrued or accumulated during such period, divided by one minus the applicable actual combined federal, state, local and foreign income tax rate of the Company and its Subsidiaries (expressed as a decimal), on a consolidated basis, for the four quarters immediately preceding the date of the transaction giving rise to the need to calculate Consolidated Interest Expense, in each case to the extent attributable to such period and excluding items 
 
2 

eliminated in consolidation. For purposes of this definition, (a) interest on a Capitalized Lease Obligation shall be deemed to accrue at an interest rate reasonably determined by the Company to be the rate of interest implicit in such Capitalized Lease Obligation in accordance with GAAP and (b) interest expense attributable to any Indebtedness represented by the guarantee by the Company or a Restricted Subsidiary of the Company of an obligation of another Person shall be deemed to be the interest expense attributable to the Indebtedness guaranteed.

Provisions relating to the Initial Securities, the Private Exchange Securities and the Exchange Securities are set forth in the Rule 144A/Regulation S Appendix attached hereto (the “Appendix”) which is hereby incorporated in and expressly made part of this Indenture. The Initial 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 Exchange Securities, the Private Exchange Securities and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit A, 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 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 A are part of the terms of this Indenture. 
 
22 

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 $300 million of Initial 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 and, in the case of an issuance of Additional Securities pursuant to Section 2.13 after the Issue Date, shall certify that such issuance is in compliance with Section 4.09. 
 
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 incorporated or organized within The United States of America may act as Paying Agent, Registrar, co-registrar or transfer agent. 
 
23 

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. 
 
24 

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 destroy (subject to the record retention requirements of the Exchange Act) all Securities surrendered for registration of transfer, exchange, payment or cancelation and deliver a certificate of such destruction 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. 
 
25 

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. 
 
SECTION 2.13. Issuance of Additional Securities. The Company shall be entitled, subject to its compliance with Section 4.09(a), to issue Additional Securities under this Indenture which shall have identical terms as the Initial Securities issued on the Issue Date, other than with respect to the date of issuance and issue price. The Initial Securities issued on the Issue Date, any Additional Securities and all Exchange Securities or Private Exchange Securities issued in exchange therefor 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; 
 
(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; and 
 
(3) whether such Additional Securities shall be Transfer Restricted Securities and issued in the form of Initial Securities as set forth in the Appendix to this Indenture or shall be issued in the form of Exchange Securities as set forth in Exhibit A. 
 
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.

REDEMPTION 
 
SECTION 3.01. Notice to Trustee. If the Company elects to redeem Securities pursuant to the optional redemption provisions of Paragraphs 
 
26 

5, 6 or 7 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, if applicable. 
 
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 
 
27 

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; 
 
(8) the paragraph of the Securities pursuant to which the Securities called for redemption are being redeemed; and 
 
(9) the CUSIP number of the Securities. 
 
(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, 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.

Principal, premium and interest shall be considered paid on the date due if the Trustee or Paying Agent holds on that date money deposited by the Company designated for and sufficient to pay all principal, premium and interest then due.

Such Officers’ Certificate shall comply with TIA Section 314(a)(4). The Company hereby represents that, as of the Issue Date, its fiscal year ends December 31, and hereby covenants that it shall notify the Trustee at least 30 days in advance of any change in its fiscal year.

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. 
 
SECTION 4.07. Payment of Taxes and Other Claims. 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. 
 
32 

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 tear excepted) and supplied with all necessary equipment and shall cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as in the judgment of the Company may be necessary so that the business carried on in connection therewith may be properly and advantageously conducted at all times; provided, however, that nothing in this Section shall prevent the Company from discontinuing the operation or maintenance of any such property, or disposing of it, if such discontinuance or disposal is, in the judgment of the Company, desirable in the conduct of its business and not disadvantageous in any material respect to the Holders. 
 
(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 Incurrence of Additional Indebtedness. 
 
(a) The Company will not, and will not permit any of its Restricted Subsidiaries, directly or indirectly, to issue, incur, assume, guarantee, become liable, contingently or otherwise, with respect to or otherwise become responsible for the payment of (collectively, “incur”) any Indebtedness; provided, however, that if no Default or Event of Default shall have occurred and be continuing at the time or as a consequence of the incurrence of such Indebtedness, the Company or its Restricted Subsidiaries may incur Indebtedness if, on a pro forma basis, after giving effect to such incurrence and the application of the proceeds therefrom, either of the following tests shall have been satisfied: (i) the Adjusted Consolidated EBITDA Coverage Ratio would have been at least 2.25 to 1.0; or (ii) Adjusted Consolidated Net Tangible Assets would have been greater than 200% of Indebtedness of the Company and its Restricted Subsidiaries. 
 
(b) Notwithstanding the foregoing, if no Default or Event of Default shall have occurred and be continuing at the time or as a consequence of the incurrence of such Indebtedness, the Company and its Restricted Subsidiaries may incur Permitted Indebtedness. For purposes of determining compliance with this Section 4.09: 
 
(i) in the event that an item of proposed Indebtedness meets the criteria of more than one of the categories of Permitted Indebtedness as of the date of incurrence thereof or is entitled to be incurred pursuant to Section 4.09(a) as of the date of incurrence thereof, the Company shall, in its sole discretion, classify (or later classify in whole or in part, in its sole discretion) such item of Indebtedness in any manner that complies with this Section 4.09, and 
 
33 

(ii) for purposes of determining compliance with any dollar-denominated restriction on the incurrence of Indebtedness denominated in a foreign currency, the dollar-equivalent principal amount of such Indebtedness incurred pursuant thereto shall be calculated based on the relevant currency. 
 
Accrual of interest or dividends, the accretion of accreted value or liquidation preference and the payment of interest or dividends in the form of additional Indebtedness will not be deemed to be an incurrence of Indebtedness for purposes of this Section 4.09. 
 
(c) Any Indebtedness of a Person existing at the time such Person becomes a Restricted Subsidiary (whether by merger, consolidation, acquisition or otherwise) shall be deemed to be incurred by such Restricted Subsidiary at the time it becomes a Restricted Subsidiary. 
 
SECTION 4.10. Limitation on Restricted Payments. (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, make any Restricted Payment, unless: 
 
(i) no Default or Event of Default shall have occurred and be continuing at the time of or immediately after giving effect to such Restricted Payment; 
 
(ii) at the time of and immediately after giving effect to such Restricted Payment, the Company would be able to incur at least $1.00 of additional Indebtedness (other than Permitted Indebtedness) pursuant to Section 4.09(a); and 
 
(iii) immediately after giving effect to such Restricted Payment, the aggregate of all Restricted Payments declared or made after the Reference Date does not exceed the sum of (A) 50% of the Consolidated Net Income of the Company and its Restricted Subsidiaries (or in the event such Consolidated Net Income shall be a deficit, minus 100% of such deficit) during the period (treated as one accounting period) subsequent to the Reference Date and ending on the last day of the fiscal quarter immediately preceding the date of such Restricted Payment; (B) the aggregate Net Cash Proceeds, and the fair market value of property other than cash (as determined in good faith by the Company’s Board of Directors and evidenced by a resolution of such Board), received by the Company during such period from any Person other than a 
 
34 

Subsidiary of the Company as a result of the issuance or sale of Capital Stock of the Company (other than any Disqualified Stock and other than Preferred Shares issued in the Preferred Stock Offering), other than in connection with the conversion of Indebtedness or Disqualified Stock; (C) the aggregate Net Cash Proceeds, and the fair market value of property other than cash (as determined in good faith by the Company’s Board of Directors and evidenced by a resolution of such Board), received by the Company during such period from any Person other than a Subsidiary of the Company as a result of the issuance or sale of any Indebtedness or Disqualified Stock to the extent that at the time the determination is made such Indebtedness or Disqualified Stock, as the case may be, has been converted into or exchanged for Capital Stock of the Company (other than Disqualified Stock); and (D)(i) in case any Unrestricted Subsidiary has been redesignated a Restricted Subsidiary, an amount equal to the lesser of (x) the book value (determined in accordance with GAAP) at the date of such redesignation of the aggregate Investments made by the Company and its Restricted Subsidiaries in such Unrestricted Subsidiary and (y) the fair market value of such Investments in such Unrestricted Subsidiary at the time of such redesignation, as determined in good faith by the Company’s Board of Directors, including a majority of the Company’s Disinterested Directors, whose determination shall be conclusive and evidenced by a resolution of such Board; or (ii) in case any Restricted Subsidiary has been redesignated an Unrestricted Subsidiary, minus the greater of (x) the book value (determined in accordance with GAAP) at the date of redesignation of the aggregate Investments made by the Company and its Restricted Subsidiaries in such Restricted Subsidiary and (y) the fair market value of such Investments in such Restricted Subsidiary at the time of such redesignation, as determined in good faith by the Company’s Board of Directors, including a majority of the Company’s Disinterested Directors, whose determination shall be conclusive and evidenced by a resolution of such Board. 
 
(b) Notwithstanding the foregoing, the above limitations will not prevent (i) the payment of any dividend within 60 days after the date of declaration thereof, if at such date of declaration such payment complied with the provisions hereof; (ii) the purchase, redemption, acquisition or retirement of any shares of Capital Stock of the Company in exchange for, or out of the net proceeds of the substantially concurrent sale (other than to a Restricted Subsidiary of the Company) of, other shares of Capital Stock (other than Disqualified Stock) of the Company; (iii) any dividend or other distribution payable from a Restricted Subsidiary to the Company or any other Restricted Subsidiary; (iv) regularly quarterly dividends on the 6.75% Cumulative Convertible Preferred Stock, the 6.00% Cumulative Convertible Preferred Stock, the 5.00% Cumulative Convertible Preferred Stock or the 4.125% Cumulative Convertible Preferred Stock of the Company outstanding on the Issue Date, provided that no Default or Event of Default shall have occurred and be continuing at the time of or immediately after giving effect to any such Restricted Payment; and (v) other Restricted Payments not in excess of $25,000,000 in the aggregate since the Issue Date, provided that no Default or Event of Default shall have occurred and be continuing at the time of or immediately after giving effect to any such Restricted Payment. Any Restricted Payment described in the preceding clause (iii) shall be excludable in the calculation of the amount of Restricted Payments, and any Restricted payment described in any other clause shall be included in the calculation. 
 
35 

SECTION 4.11. Limitation on Sale of Assets. (a) The Company will not, and will not permit any Restricted Subsidiary to, make any Asset Sale unless: 
 
(i) the Company (or its Restricted Subsidiaries, as the case may be) receives consideration at the time of such sale or other disposition at least equal to the fair market value thereof (as determined in good faith by the Company’s Board of Directors and evidenced by a resolution of such Board, including a majority of the Company’s Disinterested Directors, in the case of any Asset Sales or series of related Asset Sales having a fair market value of $20,000,000 or greater); 
 
(ii) (A) the consideration consists of cash, cash equivalents, Permitted Financial Investments or property, equipment, leasehold interests or other assets used in the Oil and Gas Business (“Permitted Consideration”) or (B) the portion of the consideration that does not constitute Permitted Consideration, together with all other consideration received for Asset Sales since the Issue Date that does not constitute Permitted Consideration, has a fair market value of no more than 10% of ACNTA; and 
 
(iii) the Net Available Proceeds received by the Company (or its Restricted Subsidiaries, as the case may be) from such Asset Sale are applied in accordance with paragraphs (b) or (c) hereof. 
 
(b) The Company may apply such Net Available Proceeds within 365 days after receipt of Net Available Proceeds from any Asset Sale, to: (i) the repayment of Indebtedness of the Company under Credit Facilities or other Senior Indebtedness, including any mandatory redemption or repurchase or optional 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. 
 
(c) If, upon completion of the 365-day period referred to above, any portion of the Net Available Proceeds of any Asset Sale 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 Asset Sale (such aggregate constituting “Excess Proceeds”), exceed $15,000,000, 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) The Company shall commence a Net Proceeds Offer by preparing and mailing a notice to the Trustee, the Paying Agent and each Holder as of such record date as the Company shall establish (upon written notice to the Trustee). Notice of a Net Proceeds Offer to purchase the Securities will be made on behalf of the Company not less 
 
36 

than 25 Business Days nor more than 60 Business Days before the payment date of the Net Proceeds Offer (the “Net Proceeds Payment Date”), and shall set forth the Net Proceeds Offer Amount and the Net Proceeds Payment Date and refer to and summarize the material points contained in Sections 4.11(d) and (e) hereof. Securities tendered to the Company pursuant to a Net Proceeds Offer will cease to accrue interest after the Net Proceeds Payment Date. For purposes of this covenant, the term “Net Proceeds Offer Amount” means the principal of outstanding Securities in an aggregate principal amount equal to any remaining Net Available Proceeds (rounded to the next lowest $1,000). If the Net Proceeds Payment Date is on or after an interest payment record date and on or before the related interest payment date, any accrued interest payable on such interest payment date will be paid to the Person in whose name a Security is registered at the close of business on such record date, and no additional interest will be payable to Holders who tender Securities pursuant to the Net Proceeds Offer. 
 
(e) On the Net Proceeds Payment Date, the Company will (i) accept for payment 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 or portions thereof pursuant to the Net Proceeds Offer in an aggregate principal amount equal to the Net Proceeds Offer Amount or such lesser amount as has been tendered, (ii) deposit with the Paying Agent (or if the Company or a Subsidiary is the Paying Agent, shall segregate and hold in trust) money sufficient to pay the purchase price of all Securities and such other Senior Indebtedness or portions thereof so tendered in an aggregate principal amount equal to the Net Proceeds Offer Amount or such lesser amount, including any accrued and unpaid interest thereon, and (iii) deliver or cause to be delivered to the Trustee, Securities so accepted together with an Officers’ Certificate stating the Securities or portions thereof tendered to the Company. If the aggregate principal amount of Securities and such other Senior Indebtedness tendered exceeds the Net Proceeds Offer Amount, the Trustee will select the Securities and other Senior Indebtedness to be purchased (in integral multiples of $1,000) on a pro rata basis based on the principal amount of Securities and other Senior Indebtedness so tendered and notify the Company, the Registrar and the Paying Agent. The Paying Agent, upon instruction of the Company, will promptly mail or deliver to 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 4.11(e)), and the Company will execute and the Trustee will promptly authenticate and mail or make available for delivery to Holders a new Security equal in principal amount to any unpurchased portion of the Security surrendered. Any Securities not so accepted will be promptly mailed or delivered to the Holder thereof by the Company, or, if the Company so directs the Trustee, by the Trustee on behalf of the Company at the Company’s expense. 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 4.11, the Trustee will 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 Asset Sale 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. 
 
(h) Notwithstanding the foregoing, the Company will not and will not permit any Restricted Subsidiary to, directly or indirectly, make any Asset Sale of any of the Capital Stock of a Restricted Subsidiary except pursuant to an Asset Sale of all of the Capital Stock of such Restricted Subsidiary. 
 
SECTION 4.12. Limitation on Liens Securing Indebtedness. The Company will not, and will not permit any of its Restricted Subsidiaries to, create, incur, assume or suffer to exist any Liens (other than Permitted Liens) upon any of their respective properties securing (i) any Indebtedness of the Company, unless the Securities are equally and ratably secured or (ii) any Indebtedness of any Restricted Subsidiary, unless the Guarantees are equally and ratably secured; provided, that if such Indebtedness is expressly subordinated to the Securities or the Guarantees, the Lien securing such Indebtedness will be subordinated and junior to any Lien securing the Securities or the Guarantees, with the same relative priority as such Subordinated Indebtedness of the Company or Subordinated Indebtedness of a Restricted Subsidiary will have with respect to the Securities or the Guarantees, as the case may be. 
 
SECTION 4.13. Limitation on Sale/Leaseback Transactions. The Company will not, and will not permit any of its Restricted Subsidiaries to, enter into any Sale/Leaseback Transaction with any Person (other than the Company or any other Restricted Subsidiary) unless (i) the Company or such Restricted Subsidiary, as the case may be, would be able to incur 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 Restricted 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 the same manner and to the same extent as Net Available Proceeds and Excess Proceeds from an Asset Sale. 
 
SECTION 4.14. Limitation on Payment Restrictions Affecting Subsidiaries. The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to exist or become effective any consensual encumbrance or consensual restriction on the ability of any Restricted Subsidiary of the Company to (i) pay dividends or make any other distributions on its Capital Stock to the Company or a Restricted Subsidiary, (ii) pay any Indebtedness owed to the Company or a Restricted Subsidiary of the Company; (iii) make loans or advances to the Company or a Restricted Subsidiary of the Company; or (iv) transfer any of its properties or assets to the Company or a Restricted Subsidiary of the Company (each, a “Payment Restriction”), except for (a) encumbrances or restrictions under Credit Facilities; provided, that any Payment Restrictions 
 
38 

thereunder (other than, with respect to (iv) above, customary restrictions in security agreements or other loan documents thereunder securing or governing Indebtedness of a Restricted Subsidiary) may be imposed only upon the acceleration of the maturity of the Indebtedness thereunder; (b) consensual encumbrances or consensual restrictions binding upon any Person at the time such Person becomes a Restricted Subsidiary of the Company (unless the agreement creating such consensual encumbrances or consensual restrictions was entered into in connection with, or in contemplation of, such entity becoming a Restricted Subsidiary); (c) consensual encumbrances or consensual restrictions under any agreement that refinances or replaces any agreement described in clauses (a) and (b) above, provided that the terms and conditions of any such restrictions are in the aggregate no less favorable to the holders of the Securities than those under the agreement so refinanced or replaced; and (d) customary non-assignment provisions in leases, purchase money financings and any encumbrance or restriction due to applicable law. 
 
SECTION 4.15. Limitation on Transactions with Affiliates. The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, enter into any transaction or series of transactions (including, without limitation, the sale, purchase or lease of any assets or properties or the rendering of any services) with any Affiliate or beneficial owner (as defined in Rules 13d-3 and 13d-5 under the Exchange Act) of 10% or more of the Company’s common stock (other than with a Restricted Subsidiary of the Company) (an “Affiliate Transaction”), on terms that are less favorable to the Company or such Restricted Subsidiary, as the case may be, than would be available in a comparable transaction with an unrelated Person. In addition, the Company will not, and will not permit any Restricted Subsidiary of the Company to, enter into an Affiliate Transaction, or any series of related Affiliate Transactions having a value of (a) more than $5,000,000 unless a majority of the Board of Directors of the Company (including a majority of the Company’s Disinterested Directors) determines in good faith, as evidenced by a resolution of such Board, that such Affiliate Transaction or series of related Affiliate Transactions is fair to the Company; or (b) more than $25,000,000, unless the Company receives a written opinion from a nationally recognized investment banking firm with total assets in excess of $1,000,000,000 that such transaction or series of transactions is fair to the Company from a financial point of view. 
 
SECTION 4.16. Change of Control. (a) Following the occurrence of any Change of Control, the Company shall offer (a “Change of Control Offer”) to purchase all outstanding Securities at a purchase price equal to 101% of the aggregate outstanding principal amount of the Securities, plus accrued and unpaid interest on the Securities so purchased to the date of purchase. The Change of Control Offer shall be deemed to have commenced upon mailing of the notice described in the next succeeding paragraph and shall terminate 20 Business Days after its commencement, unless a longer offering period is required by law. Promptly after the termination of the Change of Control Offer (the “Change of Control Payment Date”), the Company shall purchase and mail or deliver payment for all Securities tendered in response to the Change of Control Offer. If the Change of Control Payment Date is on or after an interest payment record date and on or before the related interest payment date, any accrued interest payable on such interest 
 
39 

payment date will be paid to the Person in whose name a Security is registered at the close of business on such record date, and no additional interest will be payable to Holders who tender Securities pursuant to the Change of Control Offer. 
 
(b) Within 15 days after any Change of Control, 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 Change of Control a notice prepared by the Company (the “Change of Control Notice”) of the occurrence of such Change of Control and of the Holders’ rights arising as a result thereof. The Change of Control Notice will contain all instructions and materials necessary to enable Holders to tender their Securities to the Company. The Change of Control Notice, which shall govern the terms of the Change of Control Offer, shall state: (1) that the Change of Control Offer is being made pursuant to this Section 4.16; (2) the purchase price and the Change of Control 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 Change of Control Offer shall cease to accrue interest on the Change of Control Payment Date; (5) that Holders electing to have a Security purchased pursuant to any Change of Control 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 Change of Control 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 Change of Control 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. 
 
(c) On the Change of Control Payment Date, the Company shall, to the extent permitted by applicable law, (i) accept for payment Securities or portions thereof tendered pursuant to the Change of Control 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 4.16(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 Change of Control Offer on or as soon as practicable after the Change of Control Payment Date. For purposes of this Section 4.16, the Trustee shall act as the Paying Agent. 
 
40 

(d) 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 offer by the Company to purchase the Securities at the option of the Holders upon a Change of Control.

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 Change of Control purchase price if the Event of Default includes failure to pay the Change of Control 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 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 
 
44 

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 optional redemption payments or Change of Control 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, 
 
(3) such Holder or Holders have offered to such Trustee reasonable indemnity 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 
 
45 

(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. 
 
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 
 
46 

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, 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.

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.

(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.

(a) The Trustee may rely on and shall be 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.

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

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.

and the Subsidiary Guarantors jointly and severally agree to indemnify the Trustee against any loss, liability 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 exercise or performance of any of its powers or duties hereunder. The Trustee shall notify the Company and the Subsidiary Guarantors of any claim 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 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. 
 
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. 
 
50 

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, 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 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). The Trustee shall always have a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition. The Trustee shall also comply with TIA Section 310(b). 
 
SECTION 7.11. Preferential Collection of Claims Against Company. The Trustee shall comply with TIA Section 311(a), excluding any creditor relationship listed in TIA Section 311(b). A Trustee who has resigned or been removed shall be subject to TIA Section 311(a) to the extent indicated therein. 
 
ARTICLE EIGHT 
 
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. 
 
51 

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, 4.10, 4.11, 4.12, 4.13, 4.14, 4.15 and 4.16 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. 
 
52

(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); 
 
53 

(e) Such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, this 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 
 
54 

Security which is not subject to the last paragraph of Section 8.05 and has remained unclaimed for two years after such principal, and 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, defect or inconsistency; 
 
(2) to comply with Section 5.01; 
 
(3) to reflect the addition or release of any Subsidiary Guarantor, as provided for by this Indenture; 
 
55 

(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 
 
56 

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, including premium, if any, payable upon the repurchase of any Security pursuant to Sections 4.11 or 4.16, 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. 
 
57 

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 entitled to receive, 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 
 
59 

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, (ii) immediately after such transaction, no Default or Event of Default exists, (iii) such Subsidiary Guarantor or Person formed by or surviving any such consolidation or merger will have Consolidated Tangible Net Worth (immediately after the transaction) equal to or greater than the Consolidated Tangible Net Worth of such Subsidiary Guarantor immediately preceding the transaction and (iv) the Company will, at the time of such transaction after giving pro forma effect thereto as if such transaction had occurred at the beginning of the applicable Reference Period, be permitted to incur at least $1.00 of additional Indebtedness pursuant to Section 4.09(a). 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; provided that in the event such sale or disposition constitutes an Asset Sale, the Net Available Proceeds of such sale or other disposition are applied in accordance with the provisions of this Indenture described under Section 4.11. 
 
SECTION 10.03. Addition of Subsidiary Guarantors. (a) The Company agrees to cause each Subsidiary that shall become a Restricted Subsidiary after the Issue Date to execute and deliver a supplemental indenture pursuant to which such Restricted Subsidiary shall guarantee the payment of the Securities pursuant to the terms hereof. 
 
(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 all of its assets) or (ii) the designation of a Subsidiary Guarantor as an Unrestricted Subsidiary, 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.

A-4 

Restricted Global Securities (and all Securities issued in exchange therefor or in substitution thereof) shall bear a legend in substantially the following form: 
 
THIS SECURITY (OR ITS PREDECESSOR) WAS ORIGINALLY ISSUED IN A TRANSACTION EXEMPT FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933 (THE “SECURITIES ACT”), AND THIS SECURITY MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM. EACH PURCHASER OF THIS SECURITY IS HEREBY NOTIFIED THAT THE SELLER OF THIS SECURITY MAY BE RELYING ON THE EXEMPTION FROM THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER. 
 
THE HOLDER OF THIS SECURITY AGREES FOR THE BENEFIT OF THE COMPANY THAT (A) THIS NOTE MAY BE OFFERED, RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (I) THE COMPANY, (II) IN THE UNITED STATES TO A PERSON WHOM THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A, (III) OUTSIDE THE UNITED STATES IN AN OFFSHORE TRANSACTION IN ACCORDANCE WITH RULE 904 UNDER THE SECURITIES ACT, (IV) PURSUANT TO EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER (IF AVAILABLE) OR (V) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, IN EACH OF CASES (I) THROUGH (V) IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES, AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS REQUIRED TO, NOTIFY ANY PURCHASER OF THIS SECURITY FROM IT OF THE RESALE RESTRICTIONS REFERRED TO IN (A) ABOVE. 
 
(ii) Upon any sale or transfer of a Transfer Restricted Security (including any Transfer Restricted Security represented by a Restricted Global Security) pursuant to Rule 144 under the Securities Act, the Registrar shall permit the transferee thereof to exchange such Transfer Restricted Security for a certificated Security that does not bear the legend set forth above and rescind any restriction on the transfer of such Transfer Restricted Security, if the transferor thereof certifies in writing to the Registrar that such sale or transfer was made in reliance on Rule 144 (such certification to be in the form set forth on the reverse of the Security). 
 
(iii) After a transfer of any Initial Securities or Private Exchange Securities pursuant to and during the period of the effectiveness of a Shelf Registration Statement with respect to such Initial Securities or Private Exchange Securities, as the case may be, all requirements pertaining to legends on such Initial Security or such Private Exchange Security will cease to apply, the requirements requiring any such Initial Security or such Private Exchange Security issued to certain Holders be issued in global form will cease to apply, and a certificated Initial Security or Private Exchange Security or an Initial Security or Private Exchange Security in global form, in each case without restrictive transfer legends, will be available to 
 
A-5 

the transferee of the Holder of such Initial Securities or Private Exchange Securities upon exchange of such transferring Holder’s certificated Initial Security or Private Exchange Security or directions to transfer such Holder’s interest in the Global Security, as applicable. 
 
(iv) Upon the consummation of a Registered Exchange Offer with respect to the Initial Securities, all requirements pertaining to such Initial Securities that Initial Securities issued to certain Holders be issued in global form will still apply with respect to Holders of such Initial Securities that do not exchange their Initial Securities, and Exchange Securities in certificated or global form will be available to Holders that exchange such Initial Securities in such Registered Exchange Offer. 
 
(v) Upon the consummation of a Private Exchange with respect to the Initial Securities, all requirements pertaining to such Initial Securities that Initial Securities issued to certain Holders be issued in global form will still apply with respect to Holders of such Initial Securities that do not exchange their Initial Securities, and Private Exchange Securities in global form with the global securities legend and the Restricted Securities Legend set forth in Exhibit 1 hereto will be available to Holders that exchange such Initial Securities in such Private Exchange. 
 
(c) Cancellation or Adjustment of 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.

(i) To permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate certificated Securities and Global Securities at the Registrar’s or co-registrar’s request.

(iii) The Registrar or co-registrar shall not be required to register the transfer of or exchange of any Security for a 
 
A-6 

period beginning 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. 
 
(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. 
 
(v) All Securities issued upon any transfer or exchange pursuant to the terms of this Indenture shall evidence the same debt and shall be entitled to the same benefits under this Indenture as the Securities surrendered upon such transfer or exchange. 
 
(e) No Obligation of the Trustee. 
 
(i) The Trustee shall have no responsibility or obligation to any beneficial owner of a Global Security, Agent Member or other Person with respect to the accuracy of the records of the Depository or its nominee or of any Agent Member, with respect to any ownership interest in the Securities or with respect to the delivery to any Agent Member, beneficial owner or other Person (other than the Depository) of any notice (including any notice of redemption) or the payment of any amount, under or with respect to such Securities. 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.

(b) Any Restricted Global Security that is transferable to the beneficial owners thereof pursuant to this Section shall be surrendered by the Depository to the Trustee located at its principal corporate trust office in the Borough of Manhattan, The City of New York, to be so transferred, in whole or from time to time in part, without charge, and the Trustee shall authenticate and deliver, upon such transfer of each portion of such Restricted Global Security, an equal aggregate principal amount of certificated Initial Securities of authorized denominations.

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; provided, however, that if a Registration Default (as defined in the Registration Rights Agreement) occurs, additional interest will accrue on this Security at a rate of 0.50% per annum (increasing by an additional 0.50% per annum after each consecutive 90-day period that occurs after the date on which such Registration Default occurs up to a maximum additional interest rate of 2.00%) from and including the date on which any such Registration Default shall occur to but excluding the date on which all Registration Defaults have been cured. The Company will pay interest semiannually on June 15 and December 15 of each year, commencing December 15, 2004. 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 May 27, 2004.

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).

The Company issued the Securities under an Indenture dated as of May 27, 2004 (“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, subject to its compliance with Section 4.09(a) of the Indenture, to issue Additional Securities pursuant to Section 2.13 of the Indenture.

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). 
 
9.	Change of Control Offer 	
 
In the event of a Change of Control of the Company, the Company shall be required to make an offer to purchase all or any portion of each Holder’s Securities, at 101% of the principal amount thereof, plus accrued and unpaid interest to the date of purchase. 
 
10.	Net Proceeds Offer 	
 
In the event of certain Asset Sales (and 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.

other Person or sell, lease or otherwise transfer all or substantially all of its properties or assets, the ability of the Company or the Restricted Subsidiaries to dispose of assets, to pay dividends and make certain other distributions and payments, to make certain investments or redeem, retire, repurchase or acquire for value shares of Capital Stock, to incur additional Indebtedness or incur encumbrances against certain property and to enter into certain transactions with Affiliates, all subject to certain limitations described in the Indenture. 
 
12.	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. 
 
13.	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. 
 
14.	Persons Deemed Owners 	
 
The registered Holder of this Security may be treated as the owner of it for all purposes. 
 
15.	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. 
 
16.	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. 
 
B-6 

17.	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. 
 
18.	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. 
 
19.	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. 
 
B-7 

20.	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. 
 
21.	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.

13.	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.

C-6

16.	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. 
 
17.	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. 
 
18.	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.

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 
 
C-7 

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. 
 
20.	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. 
 
21.	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.

Ladies and Gentlemen: 
 
We have acted as counsel for Chesapeake Energy Corporation, an Oklahoma corporation (the “Company”) and certain of its subsidiaries with respect to with the preparation of the Registration Statement on Form S-4 (the “Registration Statement”) filed with the Securities and Exchange Commission (the “Commission”) in connection with the registration by the Company under the Securities Act of 1933, as amended (the “Securities Act”) of (i) the offer and exchange by the Company (the “Exchange Offer”) of $300,000,000 aggregate principal amount of its 7.50% Senior Notes due 2014 (the “Initial Notes”), for a new series of notes bearing substantially identical terms and in like principal amount (the “Exchange Notes”) and (ii) the guarantees (the “Guarantees”) of certain subsidiaries of the Company listed in the Registration Statement as guarantors (the “Subsidiary Guarantors”) of the Initial Notes and the Exchange Notes. The Initial Notes were issued, and the Exchange Notes will be issued, under an Indenture dated as of May 27, 2004, among the Company, the Subsidiary Guarantors and The Bank of New York, as Trustee (the “Indenture”). The Exchange Offer will be conducted on such terms and conditions as are set forth in the prospectus contained in the Registration Statement to which this opinion is an exhibit. 
 
We have examined originals or copies, certified or otherwise identified to our satisfaction, of (i) the Registration Statement, (ii) the Indenture and (iii) such other certificates, statutes and other instruments and documents as we considered appropriate for purposes of the opinions hereafter expressed. In connection with this opinion, we have assumed that the Registration Statement, and any amendments thereto (including post-effective amendments), will have become effective and the Exchange Notes will be issued and sold in compliance with applicable federal and state securities laws and in the manner described in the Registration Statement. 
 
Based on the foregoing, we are of the opinion that when the Exchange Notes have been duly executed, authenticated, issued and delivered in accordance with the provisions of the Indenture, (i) such Exchange Notes will be legally issued and will constitute valid and binding obligations of the Company enforceable against the Company in accordance with their terms, and (ii) the Guarantees of the Subsidiary Guarantors remain valid and binding obligations of such subsidiaries, enforceable against the Company and each such Subsidiary Guarantor in accordance with their terms, except in each case as such enforcement is subject to any applicable bankruptcy, insolvency, reorganization 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. 

We are members of the bar of the State of Texas. We have relied as to matters of Oklahoma law on the opinion of Commercial Law Group, P.C., which opinion is also filed as an exhibit to the Registration Statement. The opinions expressed herein are limited exclusively to the laws of the State of New York and, in reliance on the opinion of Commercial Law Group, P.C., the laws of the State of Oklahoma, 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 firm name in the prospectus forming a part of the Registration Statement under the caption “Legal Matters.” By giving such consent, we do not admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission issued thereunder.

Ladies and Gentlemen: 
 
We have acted as special Oklahoma counsel for Chesapeake Energy Corporation, an Oklahoma corporation (the “Company”) and certain of its subsidiaries with respect to the preparation of the Registration Statement on Form S-4 (the “Registration Statement”) filed with the Securities and Exchange Commission (the “Commission”) in connection with the registration by the Company under the Securities Act of 1933, as amended (the “Securities Act”) of (i) the offer and exchange by the Company (the “Exchange Offer”) of $300,000,000 aggregate principal amount of its 7.50% Senior Notes due 2014 (the “Initial Notes”), for a new series of notes bearing substantially identical terms and in like principal amount (the “Exchange Notes”) and (ii) the guarantees (the “Guarantees”) of certain subsidiaries of the Company listed in the Registration Statement as guarantors (the “Subsidiary Guarantors”) of the Initial Notes and the Exchange Notes. The Initial Notes were issued, and the Exchange Notes will be issued, under an Indenture dated as of May 27, 2004 among the Company, the Subsidiary Guarantors and The Bank of New York, as Trustee (the “Indenture”). The Exchange Offer will be conducted on such terms and conditions as are set forth in the prospectus contained in the Registration Statement to which this opinion is an exhibit. 
 
We have examined originals or copies, certified or otherwise identified to our satisfaction, of (i) the Restated Certificate of Incorporation, as amended, and Bylaws of the Company or such documents or similar organizational documents of each of the Subsidiary Guarantors, (ii) the Indenture, (iii) the Initial Notes and (iv) such other certificates, statutes and other instruments and documents as we considered appropriate for purposes of the opinions hereafter expressed. In connection with this opinion, we have assumed that the Registration Statement, and any amendments thereto (including post-effective amendments), will have become effective and the Exchange Notes will be issued and sold in compliance with applicable federal and state securities laws and in the manner described in the Registration Statement. 
 
Based on the foregoing, we are of the opinion that the Company and the Subsidiary Guarantors have duly authorized, executed and delivered the Indenture (including, with respect to the Subsidiary Guarantors, the Guarantees contained therein) and the Initial Notes. 
 
We are members of the bar of the State of Oklahoma. The opinions expressed herein are limited exclusively to the laws of the State of Oklahoma, and we are expressing no opinion as to the effect of the laws of any other jurisdiction, domestic or foreign. We also authorize Vinson & Elkins L.L.P. to rely on this opinion in delivering its opinion.
