Unless the context otherwise requires, all references in this Prospectus to "Chesapeake" or the "Company" are to Chesapeake Energy Corporation and its subsidiaries. All references in this Prospectus to fiscal years are to the Company's fiscal year ended June 30. Certain terms used herein are defined in the Glossary included elsewhere in this Prospectus. All share information included herein has been adjusted to reflect the two-for-one stock split effected in December 1994, the three-for-two stock splits effected in December 1995 and in June 1996, and the two-for-one stock split effected in December 1996. THE COMPANY Chesapeake Energy Corporation is an independent energy company which utilizes advanced drilling and completion technologies to explore for and produce oil and natural gas. The Company is currently the third most active driller of new wells in the United States. From its inception in 1989 through December 31, 1996, Chesapeake drilled a total of 640 gross (233 net) wells, of which 603 gross (220 net) wells were commercially productive. As a result of its successful drilling efforts, the Company has experienced significant growth in its proved reserves, production, revenue, and assets. From its first full fiscal year of operation ended June 30, 1990 to the twelve months ended December 31, 1996, the Company's estimated proved reserves increased to 494 Bcfe from 11 Bcfe, annual production increased to 70 Bcfe from 0.2 Bcfe, total revenue increased to $216.6 million from $0.6 million, and total assets increased to $861 million from $8 million. At December 31, 1996, the Company's estimated proved reserves consisted of 20 MMBbl of oil and 374 Bcf of gas, a total of 494 Bcfe. During the eighteen months ended December 31, 1996, the Company's proved reserves increased from 242 Bcfe to 494 Bcfe, an increase of 252 Bcfe, or a greater than three-fold replacement of its 97 Bcfe of production during that period. At December 31, 1996 the present value of estimated future net revenue attributable to Chesapeake's estimated proved reserves before income taxes (utilizing a 10% discount rate) was $963 million, based on average prices at December 31, 1996 of $24.55 per Bbl and $3.55 per Mcf. At December 31, 1996 the Company had an inventory of approximately 1,075 undrilled locations (including 175 proved undeveloped locations), providing the Company with an estimated five-year inventory of drilling opportunities. The Company operates approximately 80% of the wells in which it owns an interest. Of the 640 wells drilled by the Company through December 31, 1996, 330 were horizontal wells, reflecting the Company's emphasis on utilizing horizontal drilling technology. BUSINESS STRATEGY Since its inception, Chesapeake's business strategy has been growth through the drillbit. Using this strategy, the Company has expanded its reserves and production through the acquisition and subsequent development of large blocks of acreage. The Company has focused its activities in areas where reservoirs such as fractured carbonates offer low geological risk, large reserve potential, and the opportunity to earn attractive economic returns through the application of advanced drilling and completion technologies. The Company's three primary operating areas are: (i) the Giddings Field of southern Texas, (ii) the Louisiana Austin Chalk Trend (the "Louisiana Trend") in eastern Texas and central Louisiana and (iii) the Knox, Sholem Alechem, and Golden Trend fields of southern Oklahoma. In addition, the Company continues to search for other areas in the United States and Canada where its geological and engineering expertise provides the Company with competitive advantages. The additional project areas identified to date include the Williston Basin in eastern Montana and western North Dakota, the Arkoma Basin in southeastern Oklahoma, the Lovington area in eastern New Mexico, the Deep Wilcox Trend in Wharton County, Texas, and the Edwards Trend along the Upper Texas Gulf Coast. Additionally, the Company has recently initiated a 3

8 leasehold acquisition program in western Canada and plans to open a district office in Calgary, Alberta in the near future. The Company's operating areas are typically characterized by fractured carbonate reservoirs that are known to contain oil and gas and generally cover a large geographic area. In the past, development of these reservoirs has been limited by both economic and technological factors. Recent advances in drilling and completion technologies, and the resulting higher reserve recoveries and lowered exploration costs, provide the Company with the opportunity to develop large new reserves of oil and natural gas and to generate attractive economic returns. On March 17, 1997, the Company consummated an offering of the Old Notes (the "Offering"), resulting in approximately $292.4 million of net proceeds to the Company. The proceeds of the Offering will allow the Company to expand further its existing exploration and development activities and to pursue new exploration projects. Management believes that the Company's growth through the drillbit business strategy, distinct competitive advantages and its successful exploration track record provide the basis for continued growth in reserves and production. Consistent with its previous statements, management seeks to achieve an investment grade senior debt rating during the next few years. COMPETITIVE ADVANTAGES Management believes five competitive advantages are responsible for Chesapeake's rapid growth and distinguish the Company from other independent energy companies. Growth Through the Drillbit. Employing its strategy of growth through the drillbit, the Company has substantially increased its reserves and production. By focusing drilling efforts on reservoirs that respond favorably to the application of advanced drilling and completion technologies, management believes the Company can continue to increase its reserves and production and generate attractive returns by integrating the Company's technical expertise with its large inventory of undeveloped leasehold. Dominant Leasehold Positions. Through aggressive acreage acquisition in its existing and new project areas, the Company seeks to establish a dominant leasehold position in each of its project areas. Such a dominant position allows the Company to maximize its economic returns while limiting drilling opportunities available to its competitors. Consistent with this strategy, the Company has assembled a significant leasehold acreage inventory which included approximately 1,075 proved and unproved drilling locations at December 31, 1996. Technological Leadership. The Company has developed significant expertise in the rapidly evolving technologies of horizontal drilling, 3-D seismic evaluation, and deep fracture stimulation. The Company believes its expertise in employing these technologies is the most important factor in its growth during the past several years. In particular, the Company has developed considerable horizontal drilling and completion expertise, especially in wells which target deep fractured carbonates. Over the last several years, deeper, more complex horizontal wells have become technically and economically feasible and the cost of drilling these wells has decreased. As a result, the Company believes there has been a substantial increase in the number of areas which are economically attractive for horizontal drilling. Superior Operating Margin. Management believes the Company's operating cost structure is among the lowest of all publicly traded independent energy producers. For the twelve months ended December 31, 1996, the Company's per unit operating costs (consisting of general and administrative expense, lease operating expense, production taxes, and depreciation, depletion and amortization of oil and gas properties) were $1.17 per Mcfe produced, resulting in an operating margin of $1.04 per Mcfe. Management believes the key to creating value in the independent energy industry is the ability to generate high levels of cash flow per Mcfe that can be successfully reinvested in a technologically-driven exploration program. Management's Substantial Equity Ownership. At February 28, 1997, the Company's management and directors beneficially owned (including outstanding vested options) an aggregate of approximately 42% of the Company's outstanding shares of Common Stock. Management believes this substantial equity ownership 4

9 provides a strong alignment of management's and investors' interests and creates an entrepreneurial culture within the Company. PRIMARY OPERATING AREAS The Company's activities are concentrated in three primary operating areas: (i) the Navasota River and Independence areas of the downdip Giddings Field in southern Texas, (ii) the South Brookeland, Leesville, Masters Creek, St. Landry, Baton Rouge and Livingston areas of the Louisiana Trend, and (iii) the Knox, Sholem Alechem, and Golden Trend fields of southern Oklahoma. GIDDINGS FIELD Chesapeake's second largest concentration of proved reserves and its highest concentration of present value are located in the Giddings Field, which is one of the most active oil and natural gas fields in the U.S. The primary producing formation in Giddings is the Austin Chalk formation, a fractured carbonate reservoir found at depths ranging from 7,000 feet to 17,000 feet along a 15,000 square mile trend in southeastern Texas and central Louisiana. Chesapeake has concentrated its drilling efforts in the gas-prone downdip portion of the Giddings Field, where the Austin Chalk is located at depths below 11,000 feet. The Company believes the downdip Giddings area is one of the largest discoveries of onshore gas in the U.S. in recent years. The Company believes that its success in the downdip Giddings Field is attributable to four principal factors: (i) limited reservoir drainage from previously drilled vertical wells; (ii) the Company's aggressive leasehold acquisition program, which has permitted the creation of larger spacing units, thus reducing competition for reserves from offsetting wells; (iii) continued technological advances in horizontal drilling, which have significantly lowered development costs, expanded the field's boundaries into deeper areas, and increased per well productivity through the ability to drill within a more precisely defined target zone; and (iv) the geological setting of the downdip Austin Chalk, which is characterized by greater reservoir pressure and more intensive fracturing than in the updip area of the Giddings Field. As a result of these factors, the Company's downdip wells have, on average, produced greater reserves per well while also exhibiting lower decline rates than average wells drilled in areas of updip Austin Chalk production. Navasota River. In February 1994, Chesapeake drilled its first well in the Navasota River leasehold block, located in Brazos and Grimes Counties, Texas. To date, the Company has successfully completed 90 of 91 Navasota River wells and is drilling nine additional wells. Independence. Chesapeake's Independence block is located in Grimes and Washington Counties to the south and southwest (and further downdip) from the Navasota River area. To date, the Company has successfully completed 29 of 32 Independence wells and is drilling two additional wells. LOUISIANA AUSTIN CHALK TREND The Louisiana Trend is the newest of the Company's primary operating areas and will be central to the Company's exploration and development activities over the next several years. As part of the Company's ongoing development of new exploration areas, the Company began intensive investigation of the geological characteristics of the Louisiana Austin Chalk in 1995. After evaluating the large number of vertical wells that were drilled during the 1970's and 1980's through the Austin Chalk to explore for deeper horizons, the Company concluded that the Austin Chalk in the Louisiana Trend offered geological characteristics similar to the Austin Chalk in the downdip Giddings Field. To capitalize on this opportunity, the Company has acquired approximately 1,200,000 acres of leasehold in the Louisiana Trend and continues to expand its leasehold. The Company commenced its first Louisiana Trend well in November 1995 and, to date, has commenced drilling operations on 27 Company-operated wells. Of these 27 wells, ten are producing, four are waiting on completion, three have been abandoned and ten have commenced drilling operations. Additionally, based on the most recent information available to the Company, management believes its competitors in the Louisiana Trend (Union Pacific Resources Corporation, Sonat Exploration Company, Occidental Petroleum Corporation, and Belco Oil & Gas Corp.) have drilled 12 successful wells out of 14 attempts in the Louisiana Trend 5

10 and are currently drilling nine additional wells. Total activity to date in the Louisiana Trend has resulted in 26 successful wells out of 31 tests, or an 84% drilling success rate. SOUTHERN OKLAHOMA Chesapeake's largest concentration of proved reserves is located in southern Oklahoma and is comprised of the Knox, Golden Trend and Sholem Alechem fields. To date, Chesapeake has successfully completed 177 of 180 wells drilled in the Knox and Golden Trend fields and is drilling six additional wells. In the Sholem Alechem portion of southern Oklahoma's Sho-Vel-Tum Field, the Company has successfully completed 27 of 27 horizontal wells in the Sycamore formation and has successfully completed its first McLish well, the industry's first horizontal test of this deeper fractured carbonate reservoir. Chesapeake is currently drilling three additional wells in this area. OTHER OPERATING AREAS Williston Basin. During fiscal 1996, Chesapeake began acquiring leasehold in the Williston Basin, located in eastern Montana and western North Dakota, and as of December 31, 1996 owned approximately 650,000 gross (500,000 net) acres. The primary focus of Chesapeake's exploration efforts in the southern portion of this basin is a horizontal drilling target, the Red River "B" formation in Bowman and Slope Counties, North Dakota and in Fallon County, Montana. Although other Red River "B" horizontal wells have been successfully drilled to date by other companies in this area, Chesapeake's first Red River "B" well was unsuccessful. Further drilling in this area is planned by the Company later in 1997. In the northern portion of the Williston Basin, the Company is focusing its exploratory efforts on drilling vertical wells to the Red River "C" and "D" formations using 3-D seismic. The Company's first three such wells were successful and accelerated drilling and 3-D seismic activity are planned for 1997. Lovington. In late 1994, Chesapeake initiated activity in the Lovington portion of the Permian Basin of Lea County, New Mexico. In this project, the Company is utilizing 3-D seismic technology to evaluate the Strawn formation in which management believes significant prospects have been overlooked because of inconclusive results provided by traditional 2-D seismic technology. The Company has been successful with its first five exploratory wells and is currently drilling two additional exploratory wells. The Company has identified approximately 50 prospects in the Lovington area and is planning to increase its drilling and seismic activity in this area in 1997. Upper Texas Gulf Coast. In this new project area, Chesapeake is pursuing two distinct geological prospects. The first, in Wharton County, targets the deep (19,000 feet) Wilcox sands that have been penetrated by the Zeidman Trustee #1, an apparent significant Wilcox discovery recently drilled by Coastal Oil & Gas Corporation and Seagull Energy Corporation. This well is the deepest well ever drilled in Wharton County and may serve as a catalyst for other deep Wilcox exploration tests in the area. Chesapeake has recently acquired 25,000 net acres of leasehold in the area near the Zeidman Trustee well and believes it is now one of the largest leasehold owners in the Zeidman Trustee well area. In addition, Chesapeake has recently drilled two successful producers in the Edwards formation, a fractured carbonate formation that is deeper than the Austin Chalk. The Company has initiated a three-county leasehold acquisition and seismic program. Canada. In the Western Sedimentary Basin of Alberta and British Columbia, Chesapeake has recently initiated several leasehold acquisition projects focused on reservoirs that the Company believes may respond favorably to the application of horizontal drilling technology. The Company plans to initiate drilling activities in Canada in late 1997 or early 1998. 6

United States Trust Company of New York is the Exchange Agent. The address, telephone number and facsimile number of the Exchange Agent are set forth in "The Exchange Offer -- Exchange Agent." SUMMARY OF TERMS OF THE NEW NOTES The Exchange Offer applies to $150,000,000 aggregate principal amount of Old Notes due 2004, and $150,000,000 principal amount of Old Notes due 2012. The form and terms of the New Notes will be identical in all material respects to the form and terms of the respective Old Notes except that (i) the New Notes will be registered under the Securities Act and, therefore, will not bear legends restricting the transfer thereof, and (ii) holders of the New Notes will not be entitled to certain rights of holders of Old Notes under the Registration Rights Agreement, which will terminate upon consummation of the Exchange Offer. The New Notes will evidence the same debt as the Old Notes, will be entitled to the benefits of the respective Indentures and will be treated as a single class thereunder with any Old Notes that remain outstanding. Following the Exchange Offer, none of the Senior Notes will be entitled to the contingent increase in interest rate provided for (in the event of a failure to consummate the Exchange Offer in accordance with the terms of the Registration Rights Agreement) pursuant to the Old Notes. See "Description of Senior Notes." Securities Offered......... $300,000,000 principal amount of New Notes, consisting of $150,000,000 principal amount of New Notes due 2004 and $150,000,000 principal amount of New Notes due 2012.

After March 15, 2004, the redemption price for the New Notes due 2012 will be the redemption prices set forth herein, plus accrued and unpaid interest to the date of redemption. See "Description of Senior Notes -- Optional Redemption." Mandatory Redemption....... None. Ranking.................... The Senior Notes are senior unsecured obligations of the Company ranking pari passu with all existing and future senior indebtedness of the Company and senior in right of payment to all subordinated indebtedness of the Company. As of December 31, 1996, after giving pro forma effect to the application of the net proceeds from the sale of the Old Notes, the Company and its Restricted Subsidiaries would have had approximately $215.7 million of senior indebtedness in addition to the Senior Notes, $5.6 million of which was secured by certain of the assets of the Company. See "Capitalization" and Note 3 of Notes to Consolidated Financial Statements incorporated by reference in this Prospectus. Guarantees................. Chesapeake is a holding company which conducts its operations through its subsidiaries. The Senior Notes are unconditionally guaranteed (the "Guarantees"), jointly and severally, by each of the Subsidiary Guarantors: Chesapeake Operating, Inc., Chesapeake Gas Development Corporation and Chesapeake Exploration Limited Partnership (also referred to as "Restricted Subsidiaries"). The Guarantees are general unsecured senior obligations of the Restricted Subsidiaries, and rank pari passu with all other senior indebtedness of the Restricted Subsidiaries, including the guarantees by the Restricted Subsidiaries of the Company's outstanding 10 1/2% Senior Notes due 2002 and 9 1/8% Senior Notes due 2006 ("Existing Notes"). See "Description of Other Indebtedness." The Guarantees may terminate under certain circumstances. See "Description of Senior Notes -- Guarantees." Certain Covenants.......... Separate indentures govern each of the New Notes due 2004 and the New Notes due 2012 (each an "Indenture," and collectively, the "Indentures") and contain certain covenants, including, but not limited to, covenants limiting the Company and its Restricted Subsidiaries with respect to the following: (i) liens, (ii) sale and leaseback transactions, and (iii) mergers and consolidations. These limitations will be subject to a number of important qualifications. See "Description of Senior Notes -- Certain Covenants." Book Entry; Delivery and Form..................... Transfers of Senior Notes between participants in The Depository Trust Company ("DTC") will be effected in the ordinary way in accordance with DTC rules and will be settled in same-day funds. See "Description of Senior Notes -- Book Entry System." 10

15 Use of Proceeds............ The Company will not receive any net proceeds from the issuance of the New Notes pursuant to this Prospectus. RISK FACTORS An investment in the New Notes involves certain risks that a potential investor should carefully evaluate prior to making an investment in the New Notes. See "Risk Factors." SUMMARY OIL AND GAS RESERVE DATA The reserve information presented below is based upon reports prepared by the independent petroleum engineering firm of Williamson Petroleum Consultants, Inc. ("Williamson") and the Company's petroleum engineers as of June 30, 1996. The reserves evaluated by the Company's petroleum engineers constituted 0.6% of the Company's total proved reserves at such date. These estimates were based on average prices realized by the Company at June 30, 1996 which resulted in average prices over the life of the production of approximately $2.41 per Mcf and $20.90 per Bbl.

These estimates were based on average prices realized by the Company at December 31, 1996, which resulted in average prices over the life of the production of approximately $3.55 per Mcf and $24.55 per Bbl. The Company's estimates of volumes of proved reserves at December 31, 1996 have not been reviewed by Williamson.

There are numerous uncertainties inherent in estimating quantities of proved reserves and in projecting future rates of production and timing of development expenditures, including many factors beyond the control of the producer. See "Risk Factors -- Uncertainty of Estimates of Oil and Gas Reserves" and "-- Commodity Price Fluctuations." 11

18 - --------------- (a) Includes a credit of $594,000 attributable to severance tax on production from prior periods. (b) Represents net income before extraordinary item plus deferred income tax expense and depreciation, depletion and amortization. (c) EBITDA represents net income of the Company and its subsidiaries from continuing operations before interest, taxes, depreciation, depletion, amortization, extraordinary items, certain other non-cash charges and, with respect to fiscal 1993, the provision for legal and other settlements. EBITDA should not be considered in isolation or as a substitute for net income, cash flows from continuing operations or other consolidated income or cash flow data prepared in accordance with generally accepted accounting principles or as a measure of the Company's profitability or liquidity. (d) For purposes of determining the ratio of earnings to fixed charges, earnings are defined as income (loss) of the Company and its subsidiaries from continuing operations before income taxes, extraordinary items and fixed charges. Fixed charges consist of interest (whether expensed or capitalized), and amortization of debt expenses and discount or premium relating to any indebtedness. Earnings were insufficient to cover fixed charges in fiscal 1993 by $464,000. (e) The pro forma data, which exclude amounts for Chesapeake Energy Marketing Inc. ("CEM"), which will not be a Subsidiary Guarantor, have been prepared on the basis of the following assumptions: (i) the Offering was consummated at the beginning of each period, (ii) $300 million principal amount of Senior Notes was outstanding during each period, (iii) interest as reported for each period was reduced by the amount of interest recorded for indebtedness which was repaid prior to the end of such period, and (iv) the outstanding balance under the Term Credit Facility was repaid at the beginning of each period. (f) Gives effect to the application of net proceeds of approximately $292.4 million from the sale of the Old Notes on March 17, 1997. 14

19 RISK FACTORS In addition to the other information set forth elsewhere or incorporated by reference in this Prospectus, the following factors relating to the Company and the Exchange Offer should be considered when evaluating an investment in the New Notes offered hereby. CONCENTRATION IN LOUISIANA TREND In addition to the development of its existing proved reserves, the Company expects that its inventory of unproved drilling locations will be the primary source of new reserves, production and cash flow over the next few years. The Louisiana Trend, in particular, is a key element of the existing inventory. The Company had invested approximately $114 million through December 31, 1996 to acquire approximately 1,200,000 acres of leasehold in the Louisiana Trend which is largely undeveloped and unproven. Moreover, approximately 40% of the Company's fiscal year 1997 drilling budget is associated with drilling and acreage acquisition activity in the Louisiana Trend. There can be no assurance that the Louisiana Trend will yield substantial economic returns. Failure of the Louisiana Trend to yield significant quantities of economically attractive reserves and production could have a material adverse impact on the Company's future financial condition and results of operations and could result in a write-off of a significant portion of its investment in the Louisiana Trend. NEED TO REPLACE RESERVES; SUBSTANTIAL CAPITAL REQUIREMENTS As is customary in the oil and gas exploration and production industry, the Company's future success depends upon its ability to find, develop or acquire additional oil and gas reserves that are economically recoverable. Unless the Company successfully replaces the reserves that it produces through successful development, exploration or acquisition, the Company's proved reserves will decline. Further, approximately 56% of the Company's estimated proved reserves at December 31, 1996 were located in the Austin Chalk formation, where wells are characterized by relatively rapid decline rates. Additionally, approximately 55% of the Company's total estimated proved reserves at December 31, 1996 were undeveloped. Recovery of such reserves will require significant capital expenditures and successful drilling operations. There can be no assurance that the Company will continue to be successful in its effort to develop or replace its proved reserves. The Company has made and intends to make substantial capital expenditures in connection with the exploration and production of its oil and gas properties. Historically, the Company has funded its capital expenditures through a combination of internally generated funds, equity and long-term debt financing, and short-term financing arrangements. The Company anticipates that the net proceeds from the Offering, together with its cash flow from operations will be sufficient to meet estimated capital expenditures through fiscal 1999, including increases in capital expenditures being presently evaluated. 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 the Company's success in locating and producing new reserves. If revenue were to decrease as a result of lower oil and gas prices, decreased production or otherwise, and the Company had no available credit facility, the Company could have a reduced ability to replace its reserves or to maintain production at current levels, potentially resulting in a decrease in production and revenue over time. If the Company's cash flow from operations are not sufficient to satisfy its capital expenditure budget, there can be no assurance that additional debt or equity financing will be available to meet these requirements. COMMODITY PRICE FLUCTUATIONS The Company's revenue, profitability and future rate of growth are substantially dependent upon prevailing prices for oil, gas and natural gas liquids, which are dependent upon numerous factors such as weather, economic, political and regulatory developments and competition from other sources of energy. The volatile nature of the energy markets makes it particularly difficult to estimate future prices of oil, gas and natural gas liquids. Prices of oil, gas and natural gas liquids are subject to wide fluctuations in response to relatively minor changes in circumstances, and there can be no assurance that future prolonged decreases in such prices will not occur. All of these factors are beyond the control of the Company. Any significant decline 15

20 in oil and gas prices could have a material adverse effect on the Company's operations, financial condition and level of expenditures for the development of its oil and gas reserves, and may result in violations of certain covenants contained in the Company's credit agreements. UNCERTAINTY OF ESTIMATES OF OIL AND GAS RESERVES There are numerous uncertainties inherent in estimating quantities of proved oil and gas reserves, including many factors beyond the control of the Company. The Company obtained an estimate of its proved oil and gas reserves and the estimated future net revenue therefrom based upon a report prepared as of June 30, 1996 by Williamson and the Company's petroleum engineers and as of December 31, 1996 prepared by the Company's petroleum engineers. The portion of the reserves evaluated solely by the Company's petroleum engineers as of June 30, 1996 constituted 0.6% of the Company's total proved reserves at that date. These estimates rely upon various assumptions, including assumptions required by the Commission as to constant 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, requiring significant decisions and assumptions in the evaluation of available geological, geophysical, engineering and economic data for each reservoir. As a result such estimates are subject to great uncertainty, and this is particularly true as to proved undeveloped reserves, which are inherently less certain than proved developed reserves and which comprise a significant portion of the Company's proved reserves. Actual future production, revenue, taxes, development expenditures, operating expenses and quantities of recoverable oil and gas reserves may vary substantially from those estimated by the Company. Any significant variance in these assumptions could materially affect the estimated quantity and value of reserves set forth in this Prospectus. In addition, the Company's reserves may be subject to downward or upward revision, based upon production history, results of future exploration and development, prevailing oil and gas prices and other factors, many of which are beyond the Company's control. DRILLING AND OPERATING RISKS Oil and gas drilling activities are subject to numerous risks, many of which are beyond the Company's control. The Company's operations may be curtailed, delayed or canceled as a result of title problems, weather conditions, compliance with governmental requirements, mechanical difficulties and shortages or delays in the delivery of equipment. In addition, the Company's properties may be susceptible to hydrocarbon drainage from production by other operators on adjacent properties. Industry operating risks include the risk of fire, explosions, blow-outs, pipe failure, abnormally pressured formations and environmental hazards such as oil spills, gas leaks, ruptures or discharges of toxic gases, the occurrence of any of which could result in substantial losses to the Company due to injury or loss of life, severe damage to or destruction of property, natural resources and equipment, pollution or other environmental damage, clean-up responsibilities, regulatory investigation and penalties and suspension of operations. The Company has been among the most active drillers of horizontal wells and expects to drill a significant number of deep horizontal wells in the future. The Company's horizontal drilling activities involve greater risk of mechanical problems than conventional vertical drilling operations. In some cases, the locations will require wells to be drilled to greater depths, which may involve more complex drilling than wells drilled to date. These wells may be significantly more expensive to drill than those drilled to date. In accordance with customary industry practice, the Company maintains insurance against some, but not all, of the risks described above. There can be no assurance that any insurance will be adequate to cover losses or liabilities. The Company cannot predict the continued availability of insurance, or its availability at premium levels that justify its purchase. RESTRICTIONS IMPOSED BY LENDERS; RESTRICTIONS IMPOSED BY LENDERS UNDER CERTAIN CIRCUMSTANCES The instruments governing the indebtedness of the Company and its Restricted Subsidiaries impose significant operating and financial restrictions on the Company. The terms of the Indentures governing the Senior Notes and the Indentures governing the Existing Notes (the "Existing Notes Indentures") affect, and in many respects significantly limit or prohibit, among other things, the ability of the Company to incur 16

21 additional indebtedness, pay dividends, repay indebtedness prior to its stated maturity, sell assets or engage in mergers or acquisitions. See "Description of Other Indebtedness" and "Description of Senior Notes -- Certain Covenants." These restrictions could also limit the ability of the Company to effect future financings, make needed capital expenditures, withstand a future downturn in the Company's business or the economy in general, or otherwise conduct necessary corporate activities. A failure by the Company to comply with these restrictions could lead to a default under the terms of such indebtedness and the Senior Notes. In the event of default, the holders of such indebtedness could elect to declare all of the funds borrowed pursuant thereto due and payable together with accrued and unpaid interest. In such event, there can be no assurance that the Company would be able to make such payments or borrow sufficient funds from alternative sources to make any such payment. Even if additional financing could be obtained, there can be no assurance that it would be on terms that are favorable or acceptable to the Company. The Company must offer to purchase the Existing Notes upon the occurrence of certain events. In the event of a Change of Control, the Company must offer to purchase all Existing Notes then outstanding at a purchase price equal to 101% of the principal amount thereof, plus accrued and unpaid interest to the date of purchase. In the event of certain asset dispositions, the Company will be required under certain circumstances to use the Excess Proceeds (as defined) to offer to purchase the Existing Notes at 100% of the principal amount thereof, plus accrued and unpaid interest to the date of purchase (a "Net Proceeds Offer"). There are no similar covenants in the Indentures. In the event the Company is required to make a Net Proceeds Offer or an offer to purchase the Existing Notes upon a Change of Control, there is no requirement that the Company make a similar offer with respect to the Senior Notes. Under such circumstances, the Senior Notes may be considered to be effectively subordinated in right of payment to the Existing Notes. See "Description of Senior Notes -- Certain Covenants" and "Description of Other Indebtedness." PATENT LITIGATION In October 1996, Union Pacific Resources Company ("UPRC") filed suit against the Company in the United States District Court for the Northern District of Texas alleging (a) infringement of UPRC's claimed patent (the "UPRC Patent") for an invention involving a method of maintaining a bore hole in a stratigraphic zone during drilling, and (b) tortious interference with contracts between UPRC and a third party vendor regarding the confidentiality of proprietary information of UPRC. UPRC is seeking injunctive relief, damages of an unspecified amount, including actual, enhanced, consequential and punitive damages, interest, costs and attorney's fees. The Company believes that it has meritorious defenses to UPRC's allegations, including, without limitation, the Company's belief that the UPRC Patent is invalid. Although the Company will vigorously defend the lawsuit, no assurance can be given as to the outcome of the matter or the ultimate impact on the Company of any damages (which could be substantial) that may be awarded to UPRC because litigation is inherently uncertain. GOVERNMENTAL REGULATION Oil and gas operations are subject to various federal, state and local governmental regulations which may be changed from time to time in response to economic or political conditions. From time to time, regulatory agencies have imposed price controls and limitations on production in order to conserve supplies of oil and gas. In addition, the production, handling, storage, transportation and disposal of oil and gas, by-products thereof and other substances and materials produced or used in connection with oil and gas operations are subject to regulation under federal, state and local laws and regulations primarily relating to protection of human health and the environment. To date, expenditures related to complying with these laws and for remediation of existing environmental contamination have not been significant in relation to the results of operations of the Company. There can be no assurance that the trend of more expansive and stricter environmental legislation and regulations will not continue. COMPETITION The Company operates in a highly competitive environment. The Company competes with major and independent oil and gas companies for the acquisition of desirable oil and gas properties, as well as for the 17

22 equipment and labor required to develop and operate such properties. Many of these competitors have financial and other resources substantially greater than those of the Company. RELIANCE ON KEY PERSONNEL; CONFLICTS OF INTEREST The Company is dependent upon its Chief Executive Officer, Aubrey K. McClendon, and its Chief Operating Officer, Tom L. Ward. The unexpected loss of the services of either of these executive officers could have a detrimental effect on the Company. The Company maintains $20 million key man life insurance policies on the life of each of Messrs. McClendon and Ward. Messrs. McClendon and Ward, together with another executive officer of the Company, have rights to, and do, participate in wells drilled by the Company. Such participation may create interests which conflict with those of the Company. CONTROL BY CERTAIN STOCKHOLDERS At February 28, 1997, Aubrey K. McClendon, Tom L. Ward, the Aubrey K. McClendon Children's Trust and the Tom L. Ward Children's Trust beneficially owned an aggregate of 24,456,768 shares (including outstanding vested options) representing approximately 34% of the Company's outstanding Common Stock, and members of the Company's Board of Directors and senior management, including Messrs. McClendon and Ward and their respective children's trusts, beneficially owned an aggregate of 28,233,074 shares (including outstanding vested options), which represented approximately 42% of the Company's outstanding Common Stock. As a result, Messrs. McClendon and Ward, together with other officers and directors of the Company, are in a position to effectively control the Company through their ability to significantly influence matters requiring the vote or consent of the Company's stockholders. ABSENCE OF A PUBLIC MARKET FOR THE SENIOR NOTES The Senior Notes are a new issue of securities with no established trading market, and there can be no assurance as to the liquidity of any markets that may develop for the Senior Notes, the ability of the holders of Senior Notes to sell their Senior Notes or the price at which holders would be able to sell their Senior Notes. Future trading prices of the Senior Notes will depend on many factors, including, among others, prevailing interest rates, the Company's operating results and the market for similar securities. The Company does not intend to apply for listing of the Senior Notes on any national securities exchange or the Nasdaq National Market. The investment banking firms which were the Initial Purchasers have informed the Company that they currently intend to make a market for the Senior Notes. However, they are not so obligated, and any such market making may be discontinued at any time without notice. See "Plan of Distribution." Accordingly, no assurance can be given that an active public or other market will develop for the Senior Notes or as to the liquidity of or the trading market for the Senior Notes. CONSEQUENCES OF THE EXCHANGE OFFER ON NON-TENDERING HOLDERS OF THE OLD NOTES In the event the Exchange Offer is consummated, the Company will not be required to register any Old Notes not tendered and accepted in the Exchange Offer. In such event, holders of Old Notes seeking liquidity in their investment would have to rely on exemptions to the registration requirements under the securities laws, including the Securities Act. Following the Exchange Offer, none of the Senior Notes will be entitled to the contingent increase in interest rate provided for (in the event of a failure to consummate the Exchange Offer in accordance with the terms of the Registration Rights Agreement) pursuant to the Old Notes. FORWARD LOOKING STATEMENTS All statements other than statements of historical fact contained in this Prospectus, including statements in "Management's Discussion and Analysis of Financial Condition and Results of Operations" incorporated by reference herein, are forward-looking statements. When used herein, the words "budget," "budgeted," "anticipate," "expects," "believes," "seeks," "goals," "intends" or "projects" and similar expressions are intended to identify forward-looking statements. It is important to note that Chesapeake's actual results could 18

23 differ materially from those projected by such forward-looking statements. Although the Company believes that the expectations reflected in such forward-looking statements are reasonable, no assurance can be given that such expectations will prove correct. Factors that could cause the Company's results to differ materially from the results discussed in such forward-looking statements include the aforementioned risks described under "Risk Factors," including, but not limited to, the following: production variances from expectations, volatility of oil and gas prices, the need to develop and replace its reserves, the substantial capital expenditures required to fund its operations, environmental risks, drilling and operating risks, risks related to exploration and development drilling, uncertainties about estimates of reserves, competition, government regulation, and the ability of the Company to implement its business strategy. All forward-looking statements in this Prospectus are expressly qualified in their entirety by the cautionary statements in this paragraph. THE COMPANY Chesapeake Energy Corporation is an independent energy company which utilizes advanced drilling and completion technologies to explore for and produce oil and natural gas. The Company's executive offices are located at 6100 North Western Avenue, Oklahoma City, Oklahoma 73118 and its telephone number is (405) 848-8000. THE EXCHANGE OFFER PURPOSE AND EFFECT OF THE EXCHANGE OFFER The Old Notes were sold by Chesapeake on March 17, 1997 to Donaldson, Lufkin & Jenrette Securities Corporation, Bear, Stearns & Co. Inc., Lehman Brothers Inc. and J.P. Morgan Securities Inc. (together, the "Initial Purchasers") in reliance on Section 4(2) of the Securities Act. The Initial Purchasers offered and sold the Old Notes only (i) to "qualified institutional buyers" (as defined in Rule 144A) in compliance with Rule 144A, (ii) to a limited number of other institutional "accredited investors" (as defined in Rule 501(a)(1), (2), (3) or (7) under the Securities Act) that, prior to their purchase of Old Notes, delivered to the Initial Purchasers a letter containing certain representations and agreements, and (iii) outside the United States to persons other than U.S. Persons, which term includes dealers or other professional fiduciaries in the United States acting on a discretionary basis for foreign beneficial owners (other than an estate or trust), in reliance upon Regulation S under the Securities Act. In connection with the sale of the Old Notes, the Company and the Initial Purchasers entered into a Registration Rights Agreement dated as of March 12, 1997 (the "Registration Rights Agreement"), which requires the Company (i) to cause the Old Notes to be registered under the Securities Act, or (ii) to file with the Commission a registration statement under the Securities Act with respect to an issue of new notes of the Company identical in all material respects to the Old Notes and use its best efforts to cause such registration statement to become effective under the Securities Act and, upon the effectiveness of that registration statement, to offer to the holders of the Old Notes the opportunity to exchange their Old Notes for a like principal amount of New Notes, which will be issued without a restrictive legend and which may be reoffered and resold by the holder without restrictions or limitations under the Securities Act. A copy of the Registration Rights Agreement has been filed as an exhibit to the Registration Statement of which this Prospectus is a part. The Exchange Offer is being made pursuant to the Registration Rights Agreement to satisfy the Company's obligations thereunder with regard to the Senior Notes. The term "Holder" with respect to the Exchange Offer means any person in whose name Old Notes are registered on the trustee's books or any other person who has obtained a properly completed bond power from the registered holder, or any person whose Old Notes are held of record by The Depository Trust Company ("DTC") who desires to deliver such Old Notes by book-entry transfer at DTC. The Company has not requested, and does not intend to request, an interpretation by the staff of the Commission with respect to whether the New Notes issued pursuant to the Exchange Offer in exchange for the Old Notes may be offered for sale, resold or otherwise transferred by any holder without compliance with the registration and prospectus delivery provisions of the Securities Act. Based on interpretations by the staff 19

24 of the Commission set forth in no-action letters issued to third parties, the Company believes the New Notes issued pursuant to the Exchange Offer in exchange for Old Notes may be offered for resale, resold and otherwise transferred by any holder thereof (other than broker-dealers, as set forth below, and any such holder that is an "affiliate" of the Company within the meaning of Rule 405 under the Securities Act) without compliance with the registration and prospectus delivery provisions of the Securities Act, provided that such Senior Notes are acquired in the ordinary course of such holder's business and that such holder has no arrangement or understanding with any person to participate in the distribution of such New Notes. Any holder who tenders in the Exchange Offer with the intention to participate, or for the purpose of participating, in a distribution of the New Notes or who is an affiliate of the Company may not rely upon such interpretations by the staff of the Commission and, in the absence of an exemption therefrom, must comply with the registration and prospectus delivery requirements of the Securities Act in connection with any secondary resale transaction. Failure to comply with such requirements in such instance may result in such holder incurring liabilities under the Securities Act for which the holder is not indemnified by the Company. Each broker-dealer (other than an affiliate of the Company) that receives Senior 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. The Letter of Transmittal states that by so acknowledging 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. The Company has agreed that, for a period of one year, if required, after the date hereof, it will make the Prospectus available to any broker-dealer for use in connection with any such resale. See "Plan of Distribution." The Exchange Offer is not being made to, nor will the Company accept surrenders for exchange from, holders of Old Notes in any jurisdiction in which this Exchange Offer or the acceptance thereof would not be in compliance with the securities or blue sky laws of such jurisdiction. By tendering in the Exchange Offer, each holder of Old Notes will represent to the Company that, among other things, (i) the New Notes acquired pursuant to the Exchange Offer are being obtained in the ordinary course of business of the person receiving such New Notes, whether or not such person is the holder, (ii) neither the holder of Old Notes nor any such other person has an arrangement or understanding with any person to participate in the distribution of such New Notes, (iii) if the holder is not a broker-dealer, or is a broker-dealer but will not receive New Notes for its own account in exchange for Old Notes, neither the holder nor any such other person is engaged in or intends to participate in the distribution of such New Notes, and (iv) neither the holder nor any such other person is an "affiliate" of the Company within the meaning of Rule 405 under the Securities Act or, if such holder is an "affiliate," that such holder will comply with the registration and prospectus delivery requirements of the Securities Act to the extent applicable. Following the completion of the Exchange Offer, none of the Senior Notes will be entitled to the contingent increase in interest rate provided pursuant to the Old Notes. Following the consummation of the Exchange Offer, holders of Senior Notes will not have any further registration rights, and the Old Notes will continue to be subject to certain restrictions on transfer. See "-- Consequences of Failure to Exchange." Accordingly, the liquidity of the market for the Old Notes could be adversely affected. See "Risk Factors -- Consequences of the Exchange Offer on Non-Tendering Holders of the Old Notes." Participation in the Exchange Offer is voluntary and holders should carefully consider whether to accept. Holders of the Old Notes are urged to consult their financial and tax advisors in making their own decisions on whether to participate in the Exchange Offer. TERMS OF THE EXCHANGE OFFER General. Upon the terms and subject to the conditions set forth in this Prospectus and in the Letter of Transmittal, the Company will accept any and all Old Notes validly tendered and not withdrawn prior to 5:00 p.m., New York City time, on the Expiration Date. Subject to the minimum denomination requirements of the New Notes, the Company will issue (a) $1,000 principal amount of New Notes due 2004 in exchange for each $1,000 principal amount of outstanding Old Notes due 2004 accepted in the Exchange Offer, and (b) $1,000 principal amount of New Notes due 2012 in exchange for each $1,000 principal amount of 20

25 outstanding Old Notes due 2012 accepted in the Exchange Offer. Holders may tender some or all of their Old Notes pursuant to the Exchange Offer. However, Old Notes may be tendered only in amounts that are integral multiples of $1,000 principal amount. The form and terms of the New Notes will be identical in all material respects to the form and terms of the Old Notes except that (i) the New Notes will be registered under the Securities Act and, therefore, will not bear legends restricting the transfer thereof, and (ii) holders of the New Notes will not be entitled to certain rights of holders of Old Notes under the Registration Rights Agreement, which will terminate upon consummation of the Exchange Offer. The New Notes will evidence the same debt as the Old Notes, will be entitled to the benefits of the respective Indentures and each series will be treated as a single class thereunder with any respective Old Notes that remain outstanding. The Exchange Offer is not conditioned upon any minimum aggregate principal amount of Old Notes being tendered for exchange. As of , 1997, $150,000,000 aggregate principal amount of the Old Notes due 2004 was outstanding and $150,000,000 aggregate principal amount of Old Notes due 2012 was outstanding. This Prospectus, together with the Letter of Transmittal, is being sent to the registered Holders of the Old Notes. Holders of Old Notes do not have any appraisal or dissenters' rights under the Oklahoma General Corporation Act or the Indenture in connection with the Exchange Offer. The Company intends to conduct the Exchange Offer in accordance with the provisions of the Registration Rights Agreement and the applicable requirements of the Exchange Act, and the rules and regulations of the Commission thereunder. Old Notes which are not tendered for exchange in the Exchange Offer will remain outstanding and interest thereon will continue to accrue, but such Old Notes will not be entitled to any rights or benefits under the Registration Rights Agreement. The Company will be deemed to have accepted validly tendered Old Notes when, as and if the Company has given oral or written notice thereof to the Exchange Agent. The Exchange Agent will act as agent for the tendering holders for the purposes of receiving the New Notes from the Company. If any tendered Old Notes are not accepted for exchange because of an invalid tender, the occurrence of certain other events set forth herein or otherwise, certificates for any such unaccepted Old Notes will be returned, without expense, to the tendering holder thereof as promptly as practicable after the Expiration Date. Holders who tender Old Notes in the Exchange Offer will not be required to pay brokerage commissions or fees or, subject to the instructions in the Letter of Transmittal, transfer taxes with respect to the exchange of Old Notes pursuant to the Exchange Offer. The Company will pay all charges and expenses, other than certain applicable taxes described below, in connection with the Exchange Offer. See "-- Fees and Expenses." Expiration Date; Extensions; Amendments. The term "Expiration Date" shall mean 5:00 p.m., New York City time, on , 1997, unless the Company, in its sole discretion, extends the Exchange Offer, in which case the term "Expiration Date" shall mean the latest date and time to which the Exchange Offer is extended. Although the Company has no current intention to extend the Exchange Offer, the Company reserves the right to extend the Exchange Offer at any time and from time to time by giving oral or written notice to the Exchange Agent and by timely public announcement communicated, unless otherwise required by applicable law or regulation, by making a release to the Dow Jones News Service. During any extension of the Exchange Offer, all Old Notes previously tendered pursuant to the Exchange Offer and not withdrawn will remain subject to the Exchange Offer. The date of the exchange of the New Notes for Old Notes will be the first New York Stock Exchange trading day following the Expiration Date. The Company reserves the right, in its sole discretion, (i) to delay accepting any Old Notes, to extend the Exchange Offer or to terminate the Exchange Offer if any of the conditions set forth below under "-- Conditions of the Exchange Offer" shall not have been satisfied, by giving oral or written notice of such delay, extension or termination to the Exchange Agent, or (ii) 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. If the Exchange Offer is amended in any manner determined by the Company to constitute a material change, the Company will promptly disclose such amendment by means of a prospectus supplement that will be distributed to the registered holders, and 21

26 the Company will extend the Exchange Offer for a period of time, depending upon the significance of the amendment and the manner of disclosure to the registered holders, if the Exchange Offer would otherwise expire during such period. In all cases, issuance of the New Notes for Old Notes that are accepted for exchange pursuant to the Exchange Offer will be made only after timely receipt by the Exchange Agent of a properly completed and duly executed Letter of Transmittal and all other required documents; provided, however, that the Company reserves the absolute right to waive any conditions of the Exchange Offer or defects or irregularities in the tender of Old Notes. If any tendered Old Notes are not accepted for any reason set forth in the terms and conditions of the Exchange Offer or if Old Notes are submitted for a greater principal amount than the holder desires to exchange, such unaccepted or non-exchanged Old Notes or substitute Old Notes evidencing the unaccepted portion, as appropriate, will be returned without expense to the tendering holder, unless otherwise provided in the Letter of Transmittal, as promptly as practicable after the expiration or termination of the Exchange Offer. Interest on the New Notes. Holders of Old Notes that are accepted for exchange will not receive accrued interest thereon at the time of exchange. However, each New Note will bear interest from the most recent date to which interest has been paid on the Old Notes or New Notes, or if no interest has been paid on the Old Notes or New Notes, from March 17, 1997. Procedures for Tendering Old Notes. The tender to the Company of Old Notes by a holder thereof pursuant to one of the procedures set forth below will constitute an agreement between such holder and the Company in accordance with the terms and subject to the conditions set forth herein and in the Letter of Transmittal. A holder of the Old Notes may tender such Old Notes by (i) properly completing and signing a Letter of Transmittal or a facsimile thereof (all references in this Prospectus to a Letter of Transmittal shall be deemed to include a facsimile thereof) and delivering the same, together with any corresponding certificate or certificates representing the Old Notes being tendered (if in certificated form) and any required signature guarantees, to the Exchange Agent at its address set forth in the Letter of Transmittal on or prior to the Expiration Date (or complying with the procedure for book-entry transfer described below), or (ii) complying with the guaranteed delivery procedures described below. If tendered Old Notes are registered in the name of the signer of the Letter of Transmittal and the New Notes to be issued in exchange therefor are to be issued (and any untendered Old Notes are to be reissued) in the name of the registered holder (which term, for the purposes described herein, shall include any participant in DTC (also referred to as a book-entry facility) whose name appears on a security listing as the owner of Old Notes), the signature of such signer need not be guaranteed. In any other case, the tendered Old Notes must be endorsed or accompanied by written instruments of transfer in form satisfactory to the Company and duly executed by the registered holder and the signature on the endorsement or instrument of transfer must be guaranteed by an eligible guarantor institution which is a member of one of the following recognized signature guarantee programs (an "Eligible Institution"): (i) The Securities Transfer Agents Medallion Program (STAMP), (ii) The New York Stock Exchange Medallion Signature Program (MSF), or (iii) The Stock Exchange Medallion Program (SEMP). If the New Notes or Old Notes not exchanged are to be delivered to an address other than that of the registered holder appearing on the note register for the Old Notes, the signature in the Letter of Transmittal must be guaranteed by an Eligible Institution. THE METHOD OF DELIVERY OF OLD NOTES, THE LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND RISK OF THE HOLDER. IF SUCH DELIVERY IS BY MAIL, IT IS RECOMMENDED THAT REGISTERED MAIL, PROPERLY INSURED, WITH RETURN RECEIPT REQUESTED, BE USED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ASSURE DELIVERY TO THE EXCHANGE AGENT BEFORE THE EXPIRATION DATE. NO LETTER OF TRANSMITTAL OR OLD NOTES SHOULD BE SENT TO THE COMPANY. HOLDERS MAY REQUEST THEIR RESPECTIVE BROKERS, DEALERS, COMMERCIAL BANKS, TRUST COMPANIES OR NOMINEES TO EFFECT THE ABOVE TRANSACTIONS FOR SUCH HOLDERS. 22

27 The Company understands that the Exchange Agent will make a request promptly after the date of this Prospectus to establish an account with respect to the Old Notes at DTC for the purpose of facilitating the Exchange Offer, and subject to the establishment thereof, any financial institution that is a participant in DTC's system may make book-entry delivery of Old Notes by causing DTC to transfer such Old Notes into the Exchange Agent's account with respect to the Old Notes in accordance with DTC's procedure for such transfer. Although delivery of the Old Notes may be effected through book-entry transfer into the Exchange Agent's account at DTC, an appropriate Letter of Transmittal with any required signature guarantee and all other required documents must in each case be transmitted to and received or confirmed by the Exchange Agent at the address set forth in the Letter of Transmittal on or prior to the Expiration Date, or, if the guaranteed delivery procedures described below are complied with, within the time period provided under such procedures. A tender will be deemed to have been received as of the date when (i) the tendering holder's properly completed and duly signed Letter of Transmittal accompanied by the Old Notes (or a confirmation of book-entry transfer of such Old Notes into the Exchange Agent's account at DTC), is received by the Exchange Agent, or (ii) a Notice of Guaranteed Delivery or letter, telegram or facsimile transmission to similar effect (as provided below) from an Eligible Institution is received by the Exchange Agent. Issuances of New Notes in exchange for Old Notes tendered pursuant to a Notice of Guaranteed Delivery or letter, telegram or facsimile transmission to similar effect (as provided below) by an Eligible Institution will be made only against submission of a duly signed Letter of Transmittal (and any other required documents) and deposit of the tendered Old Notes. All questions as to the validity, form, eligibility (including time of receipt) and acceptance for exchange of any tender of Old Notes will be determined by the Company, whose determination will be final and binding. The Company reserves the absolute right to reject any or all tenders not in proper form or the acceptance for exchange of which may, in the opinion of the Company's counsel, be unlawful. The Company also reserves the absolute right to waive any of the conditions of the Exchange Offer or any defect or irregularity in the tender of any Old Notes. None of the Company, the Exchange Agent or any other person will be under any duty to give notification of any defects or irregularities in tenders or incur any liability for failure to give any such notification. Any Old Notes received by the Exchange Agent that are not validly tendered and as to which the defects or irregularities have not been cured or waived, or if Old Notes are submitted in principal amount greater than the principal amount of Old Notes being tendered by such tendering holder, such unaccepted or non-exchanged Old Notes will be returned by the Exchange Agent to the tendering holder, unless otherwise provided in the Letter of Transmittal, as soon as practicable following the Expiration Date. In addition, the Company reserves the right in its sole discretion (a) to purchase or make offers for any Old Notes that remain outstanding subsequent to the Expiration Date, and (b) to the extent permitted by applicable law, to purchase Old Notes in the open market, in privately negotiated transactions or otherwise. The terms of any such purchases or offers will differ from the terms of the Exchange Offer. Guaranteed Delivery Procedures. If the holder desires to accept the Exchange Offer and time will not permit a Letter of Transmittal or Old Notes to reach the Exchange Agent before the Expiration Date or the procedure for book-entry transfer cannot be completed on a timely basis, a tender may be effected if the Exchange Agent has received at its office, on or prior to the Expiration Date, a letter, telegram or facsimile transmission from an Eligible Institution setting forth the name and address of the tendering holder, the name(s) in which the Old Notes are registered and the certificate number(s) of the Old Notes to be tendered, and stating that the tender is being made thereby and guaranteeing that, within three New York Stock Exchange trading days after the date of execution of such letter, telegram or facsimile transmission by the Eligible Institution, such Old Notes, in proper form for transfer (or a confirmation of book-entry transfer of such Old Notes into the Exchange Agent's account at DTC), will be delivered by such Eligible Institution together with a properly completed and duly executed Letter of Transmittal (and any other required documents). Unless Old Notes being tendered by the above-described method are deposited with the Exchange Agent within the time period set forth above (accompanied or preceded by a properly competed Letter of Transmittal and any other required documents), the Company may, at its option, reject the tender. 23

28 Copies of a Notice of Guaranteed Delivery which may be used by Eligible Institutions for the purposes described in this paragraph are available from the Exchange Agent. Terms and Conditions of the Letter of Transmittal. The Letter of Transmittal contains, among other things, the following terms and conditions, which are part of the Exchange Offer. The party tendering Old Notes for exchange (the "Transferor") exchanges, assigns and transfers the Old Notes to the Company and irrevocably constitutes and appoints the Exchange Agent as the Transferor's agent and attorney-in-fact to cause the Old Notes to be assigned, transferred and exchanged. The Transferor represents and warrants that it has full power and authority to tender, exchange, assign and transfer the Old Notes and to acquire New Notes issuable upon the exchange of such tendered Old Notes, and that, when the same are accepted for exchange, the Company will acquire good and unencumbered title to the tendered Old Notes, free and clear of all liens, restrictions, charges and encumbrances and not subject to any adverse claim. The Transferor also warrants that it will, upon request, execute and deliver any additional documents deemed by the Company to be necessary or desirable to complete the exchange, assignment and transfer of tendered Old Notes or to transfer ownership of such Old Notes on the account books maintained by DTC. All authority conferred by the Transferor will survive the death, bankruptcy or incapacity of the Transferor and every obligation of the Transferor shall be binding upon the heirs, personal representatives, executors, administrators, successors, assigns, trustees in bankruptcy and other legal representatives of such Transferor. By executing a Letter of Transmittal, each holder will make to the Company the representations set forth above under the heading "-- Purpose and Effect of the Exchange Offer." Withdrawal of Tenders of Old Notes. Except as otherwise provided herein, tenders of Old Notes may be withdrawn at any time prior to 5:00 p.m., New York City time, on the Expiration Date. To withdraw a tender of Old Notes in the Exchange Offer, a written or facsimile transmission notice of withdrawal must be received by the Exchange Agent at its address set forth herein prior to 5:00 p.m., New York City time, on the Expiration Date. Any such notice of withdrawal must (i) specify the name of the person having deposited the Old Notes to be withdrawn (the "Depositor"), (ii) identify the Old Notes to be withdrawn (including the certificate number or numbers and principal amount of such Old Notes), (iii) contain a statement that such holder is withdrawing its election to have such Old Notes exchanged, (iv) be signed by the holder in the same manner as the original signature on the Letter of Transmittal by which such Old Notes were tendered (including any required signature guarantees) or be accompanied by documents of transfer sufficient to have the Trustee with respect to the Old Notes register the transfer of such Old Notes in the name of the person withdrawing the tender, and (v) specify the name in which any such Old Notes are to be registered, if different from that of the Depositor. If Old Notes have been tendered pursuant to the procedure for book-entry transfer, any notice of withdrawal must specify the name and number of the account at the book-entry transfer facility. All questions as to the validity, form and eligibility (including time of receipt) of such notices will be determined by the Company, whose determination shall be final and binding on all parties. Any Old Notes so withdrawn will be deemed not to have been validly tendered for purposes of the Exchange Offer and no New Notes will be issued with respect thereto unless the Old Notes so withdrawn are validly retendered. Any Old Notes which have been tendered but which are not accepted for exchange will be returned to the holder thereof without cost to such holder as soon as practicable after withdrawal, rejection of tender or termination of the Exchange Offer. Properly withdrawn Old Notes may be retendered by following one of the procedures described above under "-- Procedures for Tendering Old Notes" at any time prior to the Expiration Date. 24

29 CONDITIONS OF THE EXCHANGE OFFER Notwithstanding any other term of the Exchange Offer, or any extension of the Exchange Offer, the Company shall not be required to accept for exchange, or exchange New Notes for, any Old Notes, and may terminate the Exchange Offer as provided herein before the acceptance of such Old Notes, if: (a) any statute, rule or regulation shall have been enacted, or any action shall have been taken by any court or governmental authority which, in the reasonable judgment of the Company, would prohibit, restrict or otherwise render illegal consummation of the Exchange Offer; or (b) any change, or any development involving a prospective change, in the business or financial affairs of the Company or any of its subsidiaries has occurred which, in the sole judgment of the Company, might materially impair the ability of the Company to proceed with the Exchange Offer or materially impair the contemplated benefits of the Exchange Offer to the Company; or (c) there shall occur a change in the current interpretations by the staff of the Commission which, in the Company's reasonable judgment, might materially impair the Company's ability to proceed with the Exchange Offer. If the Company determines in its sole discretion that any of the above conditions are not satisfied, the Company may (i) refuse to accept any Old Notes and return all tendered Old Notes to the tendering holders, (ii) extend the Exchange Offer and retain all Old Notes tendered prior to the Expiration Date, subject, however, to the right of holders to withdraw such Old Notes (see "-- Terms of the Exchange Offer -- Withdrawal of Tenders of Old Notes"), or (iii) waive such unsatisfied conditions with respect to the Exchange Offer and accept all validly tendered Old Notes which have not been withdrawn. If such waiver constitutes a material change to the Exchange Offer, the Company will promptly disclose such waiver by means of a prospectus supplement that will be distributed to the registered holders, and the Company will extend the Exchange Offer for a period of time, depending upon the significance of the waiver and the manner of disclosure to the registered holders, if the Exchange Offer would otherwise expire during such period. EXCHANGE AGENT United States Trust Company of New York has been appointed as Exchange Agent for the Exchange Offer. Questions and requests for assistance, requests for additional copies of this Prospectus or of the Letter of Transmittal and requests for Notices of Guaranteed Delivery should be directed to the Exchange Agent addressed as follows: By Mail: By Overnight Courier: By Hand: United States Trust Company United States Trust Company United States Trust Company of New York of New York of New York P. O. Box 844 Corporate Trust Operations 111 Broadway Cooper Station Department Lower Level New York, NY 10276-0844 770 Broadway -- 13th Floor New York, NY 10006 (registered or certified mail New York, NY 10003 Attn: Corporate Trust Services recommended) By Facsimile: (212) 420-6152 (For Eligible Institutions Only) Confirm by Telephone: (800) 548-6565 FEES AND EXPENSES The expenses of soliciting tenders will be borne by the Company. The principal solicitation is being made by mail; however, additional solicitation may be made by telecopy, telephone or in person by officers and 25

30 regular employees of the Company and its affiliates. No additional compensation will be paid to any such officers and employees who engage in soliciting tenders. The Company has not retained any dealer-manager or other soliciting agent in connection with the Exchange Offer and will not make any payments to brokers, dealers or others soliciting acceptance of the Exchange Offer. The Company, however, will pay the Exchange Agent reasonable and customary fees for its services and will reimburse it for its reasonable out-of-pocket expenses in connection therewith. The Company may also pay brokerage houses and other custodians, nominees and fiduciaries the reasonable out-of-pocket expenses incurred by them in forwarding copies of this Prospectus, the Letter of Transmittal and related documents to the beneficial owners of the Old Notes and in handling or forwarding tenders for exchange. The expenses to be incurred in connection with the Exchange Offer will be paid by the Company. Such expenses include fees and expenses of the Exchange Agent and transfer agent and registrar, accounting and legal fees and printing costs, among others. The Company will pay all transfer taxes, if any, applicable to the exchange of the Old Notes pursuant to the Exchange Offer. If, however, New Notes, or Old Notes for principal amounts not tendered or accepted for exchange, are to be delivered to, or are to be issued in the name of, any person other than the registered holder of the Old Notes tendered or if a transfer tax is imposed for any reason other than the exchange of the Old Notes pursuant to the Exchange Offer, then the amount of any such transfer taxes (whether imposed on the registered holder or any other persons) will be payable by the tendering holder. If satisfactory evidence of payment of such taxes or exemption therefrom is not submitted with the Letter of Transmittal, the amount of such transfer taxes will be billed directly to such tendering holder. CONSEQUENCES OF FAILURE TO EXCHANGE The Old Notes that are not exchanged for New Notes pursuant to the Exchange Offer will remain restricted securities within the meaning of Rule 144 of the Securities Act. Accordingly, such Old Notes may be offered, resold, pledged or otherwise transferred only (i) to the Company, (ii) to a person who the transferor reasonably believes is a qualified institutional buyer in compliance with Rule 144A, (iii) pursuant to the exemption from registration provided by Rule 144 under the Securities Act (if available), (iv) outside the United States to a foreign person in compliance with Rule 904 under the Securities Act, (v) in accordance with another exemption from the registration requirements of the Securities Act (and based upon an opinion of counsel if the Company so requests) or (vi) pursuant to an effective registration statement under the Securities Act. The liquidity of the Old Notes could be adversely affected by the Exchange Offer. Following the consummation of the Exchange Offer, holders of the Old Notes will have no further registration rights under the Registration Rights Agreement and will not be entitled to the contingent increase in the interest rate provided for in the Old Notes. ACCOUNTING TREATMENT The New Notes will be recorded at the same carrying value as the Old Notes, as reflected in the Company's accounting records on the date of the exchange. Accordingly, no gain or loss for accounting purposes will be recognized by the Company. The costs of the Exchange Offer and the unamortized expenses related to the issuance of the Old Notes will be amortized over the term of the New Notes. USE OF PROCEEDS The Company will not receive any proceeds from the issuance of the New Notes offered hereby. In consideration for issuing the New Notes as contemplated in this Prospectus, the Company will receive in exchange Old Notes in like principal amount, the term and form of which are identical in all material respects to the New Notes. The Old Notes surrendered in exchange for New Notes will be retired and canceled and cannot be reissued. Accordingly, issuance of the New Notes will not result in any increase in the indebtedness of the Company. 26

The Existing Notes are senior, unsecured obligations of the Company that rank pari passu in right of payment with all existing and future Senior Indebtedness of the Company and rank senior in right of payment to all existing and future subordinated indebtedness of the Company. The Existing Notes are fully and unconditionally guaranteed, jointly and severally, by the Restricted Subsidiaries. Optional Redemption. At any time on or after June 1, 1999, the Company may, at its option, redeem all or any portion of the 10 1/2% Notes at the redemption prices (expressed as percentages of the principal amount of the 10 1/2% Notes) set forth below, plus, in each case, accrued interest thereon to the applicable redemption date, if redeemed during the twelve-month period beginning June 1 of the years indicated: YEAR PERCENTAGE ---- ---------- 1999................................................ 105.250% 2000................................................ 102.625% 2001 and thereafter................................. 100.000% Notwithstanding the foregoing, in the event the Company consummates one or more Equity Offerings on or prior to June 1, 1998, the Company, at its option, may redeem up to $30 million of the aggregate principal amount of the 10 1/2% Notes with all or a portion of the aggregate net proceeds received by the Company from such Equity Offerings at a redemption price of 110% of the aggregate principal amount of the 10 1/2% Notes so redeemed, plus accrued and unpaid interest thereon to the redemption date; provided, however, that following such redemption, at least $60 million of the aggregate principal amount of the 10 1/2% Notes remains outstanding.

33 Change of Control. The Existing Notes Indentures provide that, following the occurrence of any Change of Control, the Company must offer to purchase all outstanding Existing Notes at a purchase price equal to 101% of the aggregate principal amount of the Existing Notes, plus accrued and unpaid interest to the date of purchase. Restrictive Covenants. The Existing Notes Indentures contain restrictive covenants that limit the Company and its Restricted Subsidiaries with respect to certain matters, including changes in business, liens, debt, mergers, dividends, investments, sale and leaseback transactions, transactions with affiliates, and sales of assets. In the event of certain asset dispositions, the Company will be required, under certain circumstances, to use Excess Proceeds to offer to purchase Existing Notes at 100% of the principal amount thereof, plus accrued and unpaid interest. The Existing Notes Indenture applicable to the 10 1/2% Notes (the "10 1/2% Notes Indenture") prohibits the Company and any Restricted Subsidiary from incurring Indebtedness, other than Permitted Indebtedness, unless (i) the Adjusted Consolidated EBITDDA Coverage Ratio is at least 2.5-to-1.0, and (ii) ACNTA is at least 125% of Indebtedness of the Company and its Restricted Subsidiaries. The 10 1/2% Notes Indenture permits the Company and its Restricted Subsidiaries to incur Permitted Indebtedness under a bank credit facility not in excess of the greater of $15 million and 15% of ACNTA. The Existing Notes Indenture applicable to the 9 1/8% Notes (the "9 1/8% Notes Indenture") prohibits the Company and any Restricted Subsidiary from incurring Indebtedness, other than Permitted Indebtedness, unless (i) the Adjusted Consolidated EBITDA Coverage Ratio is at least 2.5-to-1.0, or (ii) ACNTA is at least 200% of Indebtedness of the Company and its Restricted Subsidiaries. The 9 1/8% Notes Indenture permits the Company and its Restricted Subsidiaries to incur Permitted Indebtedness under a bank credit facility not in excess of the greater of (a) $75 million and (b) $30 million plus 15% of ACNTA. DESCRIPTION OF SENIOR NOTES The Company will issue up to $150 million aggregate principal amount of New Notes due 2004 and up to $150 million of New Notes due 2012 (less the aggregate principal amount of Old Notes that are not exchanged), pursuant to separate Indentures, each dated as of March 15, 1997 among the Company, the Restricted Subsidiaries and United States Trust Company of New York, as trustee (the "Trustee"). A copy of each Indenture is available upon request from the Company and is filed as an exhibit to the Registration Statement of which this Prospectus is a part. The following summaries of certain provisions of the Senior Notes, including the New Notes, and the Indentures do not purport to be complete and are subject to, and are qualified in their entirety by reference to, the Senior Notes and the Indentures, including the definitions therein of certain capitalized terms used but not defined herein. GENERAL The aggregate principal amount of the Senior Notes is limited to $300,000,000, consisting of $150,000,000 principal amount of New Notes due 2004 and Old Notes due 2004 (together, the "Senior Notes due 2004") and $150,000,000 principal amount of New Notes due 2012 and Old Notes due 2012 (together, the "Senior Notes due 2012"). Each Senior Note due 2004 will mature on March 15, 2004 and will bear interest at an annual rate of 7 7/8% per annum. Each Senior Note due 2012 will mature on March 15, 2012 and will bear interest at an annual rate of 8 1/2% per annum. Interest on the Senior Notes will accrue from their respective dates of original issuance, payable semiannually in arrears on March 15 and September 15 of each year, commencing September 15, 1997, to the Person in whose name the Senior Note is registered at the close of business on March 1 or September 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 may be made by check mailed to the address of the Person entitled thereto as it appears in the register of the Senior Notes maintained by the Registrar. Initially, the Trustee will also act as Paying Agent and Registrar for the Senior Notes. The Senior Notes are senior unsecured obligations of the Company. The Senior Notes rank pari passu in right of payment with all existing and future Pari Passu Indebtedness of the Company and rank senior in right 29

34 of payment to all existing and future Subordinated Indebtedness of the Company. At December 31, 1996, on a pro forma basis after giving effect to the sale of the Old Notes and the application of the net proceeds therefrom, the Company and its Restricted Subsidiaries would have had Pari Passu Indebtedness in addition to the Senior Notes of approximately $215.7 million, of which $5.6 million was secured by certain assets of the Company, and no Indebtedness would have ranked junior to the Senior Notes in right of payment. GUARANTEES All of the subsidiaries of the Company other than CEM and Chesapeake Canada Corporation have fully and unconditionally guaranteed, on a joint and several basis, the Company's obligations to pay principal of, premium, if any, and interest on the Senior Notes. Each of the Indentures provides that each Person other than a Foreign Subsidiary that becomes a Restricted Subsidiary after the Issue Date will guarantee the payment of the Senior Notes. Each of the Guarantees is a senior obligation of the Subsidiary Guarantors providing such Guarantee, and ranks pari passu in right of payment with all existing and future Pari Passu Indebtedness of such Subsidiary Guarantor, except to the extent of collateral securing such Pari Passu Indebtedness, and ranks senior to all existing and future Subordinated Indebtedness of such Subsidiary Guarantor. The Guarantees rank pari passu in right of payment with the guarantees by the Subsidiary Guarantors of the Existing Notes. The obligations of each Subsidiary Guarantor are limited to the amount as will, after giving effect to all other contingent and fixed liabilities of such Subsidiary Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Subsidiary Guarantor in respect of the obligations of such other Subsidiary Guarantor under its Guarantee or pursuant to its contribution obligations under the Indentures, result in the obligations of such Subsidiary Guarantor under its Guarantee not 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 Adjusted Net Assets of each Subsidiary Guarantor. Each of the Indentures provides that, 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 entity or Person) another corporation, entity or Person unless (i) the entity or Person formed by or surviving any such consolidation or merger (if other than such Subsidiary Guarantor) assumes all the obligations of such Subsidiary Guarantor pursuant to a supplemental indenture, in a form reasonably satisfactory to the Trustee, under the Senior Notes to which such Indenture relates and such Indenture, and (ii) immediately after such transaction, no Default or Event of Default exists. The foregoing will not prohibit a merger between Subsidiary Guarantors or a merger between the Company and a Subsidiary Guarantor. Each of the Indentures provides that in the event of a sale or other disposition of all or substantially all of the assets of any Subsidiary Guarantor, by way of merger, consolidation or otherwise, or a sale or other disposition of all of the capital stock or other ownership interests of such Subsidiary Guarantor, or a Subsidiary ceases to be a Subsidiary Guarantor, then such Subsidiary (in the event of a sale or other disposition, by way of such a merger, consolidation or otherwise, of all of the capital stock or other ownership interests of such Subsidiary) or the corporation acquiring the property (in the event of a sale or other disposition of all or substantially all of the assets of such Subsidiary) will be released and relieved of any obligations under its Guarantees. In addition, each of the Indentures provides that if, at any time while Senior Notes to which such Indenture relates remain outstanding, none of the Company's then outstanding Pari Passu Indebtedness (other than Senior Notes) is guaranteed by a Subsidiary Guarantor, such Subsidiary Guarantor shall be released and relieved of any obligations under its Guarantees (which shall be terminated and cease to have any force and effect). The Indentures provide that if any Subsidiary of the Company that is not a Subsidiary Guarantor guarantees any Funded Indebtedness of the Company at any time in the future, then the Company will cause the Senior Notes to be equally and ratably guaranteed by such Subsidiary. 30

35 OPTIONAL REDEMPTION Senior Notes. The Company may at any time prior to March 15, 2004, at its option, redeem all or any portion of either series of the Senior Notes at the Make-Whole Price plus accrued and unpaid interest to the date of redemption. Senior Notes due 2012. At any time on or after March 15, 2004, the Company may, at its option, redeem all or any portion of the Senior Notes due 2012 at the redemption prices (expressed as percentages of the principal amount of the Senior Notes due 2012) set forth below, plus, in each case, accrued and unpaid interest thereon to the applicable redemption date, if redeemed during the twelve-month period beginning March 15 of the years indicated below: YEAR PERCENTAGE ---- ---------- 2004.............................................. 104.25% 2005.............................................. 103.40% 2006.............................................. 102.55% 2007.............................................. 101.70% 2008.............................................. 100.85% 2009 and thereafter............................... 100.00% If less than all of a series of the Senior Notes are to be redeemed at any time, selection of Senior Notes of such series for redemption will be made by the Trustee on a pro rata basis, by lot or by any other method that the Trustee considers fair and appropriate and that complies with the requirements of any securities exchange on which such series of the Senior Notes may be listed, provided that no Senior Notes with a principal amount of $1,000 or less will be redeemed in part. Notice of redemption will be mailed by first class mail at least 30 but not more than 60 days before the redemption date to each Holder of Senior Notes to be redeemed at its registered address. If any Senior Note is to be redeemed in part only, the notice of redemption that relates to such Senior Note will state the portion of the principal amount thereof to be redeemed. A new Senior Note in a principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon cancellation of the original Senior Note. On and after the redemption date interest ceases to accrue on Senior Notes or portions of them called for redemption. CERTAIN COVENANTS Nothing in either of the Indentures or either series of the Senior Notes will in any way limit the amount of Indebtedness or securities (other than the Senior Notes) that the Company or any of its Subsidiaries may incur or issue. The Indentures provide that the following restrictive covenants will be applicable to the Company and its Restricted Subsidiaries. Limitation on Liens. The Indentures will provide that the Company will not, and will not permit any Restricted Subsidiary to, issue, assume or guarantee any Indebtedness for borrowed money secured by any Lien on any property or asset now owned or hereafter acquired by the Company or such Restricted Subsidiary without making effective provision whereby any and all Senior Notes then or thereafter outstanding will be secured by a Lien equally and ratably with any and all other obligations thereby secured for so long as any such obligations shall be so secured. The foregoing restriction will not, however, apply to: (a) Liens existing on the date on which the Senior Notes are originally issued or provided for under the terms of agreements existing on such date; (b) Liens on property securing (i) all or any portion of the cost of exploration, drilling or development of such property, (ii) all or any portion of the cost of acquiring, constructing, altering, improving or repairing any property or assets, real or personal, or improvements used or to be used in connection with such property or (iii) Indebtedness incurred by the Company or any Restricted Subsidiary to provide funds for the activities set forth in clauses (i) and (ii) above; 31

36 (c) Liens securing Indebtedness owed by a Restricted Subsidiary to the Company or to any other Restricted Subsidiary; (d) Liens on property existing at the time of acquisition of such property by the Company or a Subsidiary or Liens on the property of any corporation or other entity existing at the time such corporation or other entity becomes a Restricted Subsidiary of the Company or is merged with the Company in compliance with the Indentures and in either case not incurred as a result of (or in connection with or in anticipation of) the acquisition of such property or such corporation or other entity becoming a Restricted Subsidiary of the Company or being merged with the Company, provided that such Liens do not extend to or cover any property or assets of the Company or any of its Restricted Subsidiaries other than the property so acquired; (e) Liens on any property securing (i) Indebtedness incurred in connection with the construction, installation or financing of pollution control or abatement facilities or other forms of industrial revenue bond financing or (ii) Indebtedness issued or guaranteed by the United States or any State thereof or any department, agency or instrumentality of either; (f) any Lien extending, renewing or replacing (or successive extensions, renewals or replacements of) any Lien of any type permitted under clauses (a) through (e) above, provided that such Lien extends to or covers only the property that is subject to the Lien being extended, renewed or replaced; (g) certain Liens arising in the ordinary course of business of the Company and the Restricted Subsidiaries; (h) any Lien resulting from the deposit of moneys or evidences of indebtedness in trust for the purpose of defeasing Indebtedness of the Company or any Restricted Subsidiary; or (i) Liens (exclusive of any Lien of any type otherwise permitted under clauses (a) through (h) above) securing Indebtedness of the Company or any Restricted Subsidiary in an aggregate principal amount which, together with the aggregate amount of Attributable Indebtedness deemed to be outstanding in respect of all Sale/Leaseback Transactions entered into pursuant to clause (a) of the covenant described under "Limitation on Sale/Leaseback Transactions" below (exclusive of any such Sale/Leaseback Transactions otherwise permitted under clauses (a) through (h) above), does not at the time such Indebtedness is incurred exceed 15% of ACNTA. The following types of transactions will not be prohibited or otherwise limited by the foregoing covenant: (i) the sale, granting of Liens with respect to, or other transfer of, crude oil, natural gas or other petroleum hydrocarbons in place for a period of time until, or in an amount such that, the transferee will realize therefrom a specified amount (however determined) of money or of such crude oil, natural gas or other petroleum hydrocarbons; (ii) the sale or other transfer of any other interest in property of the character commonly referred to as a production payment, overriding royalty, forward sale or similar interest; (iii) the entering into of Currency Hedge Obligations, Interest Rate Hedging Agreements or Oil and Gas Hedging Contracts although Liens securing any Indebtedness for borrowed money that is the subject of any such obligation shall not be permitted hereby unless permitted under clauses (a) through (i) above; and (iv) the granting of Liens required by any contract or statute in order to permit the Company or any Restricted Subsidiary to perform any contract or subcontract made by it with or at the request of the United States or any State thereof or any department, agency or instrumentality of either, or to secure partial, progress, advance or other payments to the Company or any Restricted Subsidiary by such governmental unit pursuant to the provisions of any contract or statute. Limitation of Sale/Leaseback Transactions. The Indentures will provide that the Company will not, and will not permit any Restricted Subsidiary to, enter into any Sale/Leaseback Transaction with any person (other than the Company or a Restricted Subsidiary) unless: (a) the Company or such Restricted Subsidiary would be entitled to incur Indebtedness, in a principal amount equal to the Attributable Indebtedness with respect to such Sale/Leaseback Transaction, secured by a Lien on the property subject to such Sale/Leaseback Transaction pursuant to the 32

37 covenant described under "-- Limitation on Liens" above without equally and ratably securing the Senior Notes pursuant to such covenant; (b) after the date on which the Senior Notes are originally issued and within a period commencing six months prior to the consummation of such Sale/Leaseback Transaction and ending six months after the consummation thereof, the Company or such Restricted Subsidiary shall have expended for property used or to be used in the ordinary course of business of the Company and the Restricted Subsidiaries (including amounts expended for the exploration, drilling or development thereof, and for additions, alterations, repairs and improvements thereto) an amount equal to all or a portion of the net proceeds of such Sale/Leaseback Transaction and the Company shall have elected to designate such amount as a credit against such Sale/Leaseback Transaction (with any such amount not being so designated to be applied as set forth in clause (c) below); or (c) the Company, during the twelve-month period after the effective date of such Sale/Leaseback Transaction, shall have applied to the voluntary defeasance or retirement of a series of Senior Notes or any Pari Passu Indebtedness an amount equal to the greater of the net proceeds of the sale or transfer of the property leased in such Sale/Leaseback Transaction and the fair value, as determined by the Board of Directors of the Company, of such property at the time of entering into such Sale/Leaseback Transaction (in either case adjusted to reflect the remaining term of the lease and any amount expended by the Company as set forth in clause (b) above), less an amount equal to the principal amount of Senior Notes and Pari Passu Indebtedness voluntarily defeased or retired by the Company within such twelve-month period and not designated as a credit against any other Sale/Leaseback Transaction entered into by the Company or any Restricted Subsidiary during such period. Limitations on Mergers and Consolidations.

Each of the Indentures provides that if an Event of Default occurs and is continuing with respect to the Indenture, the Trustee or the Holders of not less than 25% in principal amount of such Senior Notes 38

43 outstanding may declare the principal of and premium, if any, and accrued but unpaid interest on all such Senior Notes to be due and payable. Upon such a declaration, such principal premium, if any, and interest will be due and payable immediately. If an Event of Default relating to certain events of bankruptcy, insolvency or reorganization of the Company or any Subsidiary of the Company occurs and is continuing, the principal of, and premium, if any, and interest on all the Senior 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 Senior Notes.

The Holders of a majority in principal amount of each series of the Senior 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 under the Indenture relating to such series of Senior Notes, subject to certain limitations specified in such Indenture. Each of the Indentures will require the annual filing by the Company with the Trustee of a written statement as to compliance with the covenants contained in such Indenture. MODIFICATION AND WAIVER Each of the Indentures provides that modifications and amendments to the Indenture or the series of Senior Notes subject thereto 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 such series of Senior Notes then outstanding; provided that no such modification or amendment may, without the consent of the Holder of each Senior Note of such series then outstanding affected thereby, (i) reduce the percentage of principal amount of Senior Notes of such series whose Holders must consent to an amendment, supplement or waiver; (ii) reduce the rate or change the time for payment of interest, including default interest, on any such Senior Note; (iii) reduce the principal amount of any such Senior Note or change the Maturity Date of the Senior Notes; (iv) reduce the redemption price, including premium, if any, payable upon redemption of any Senior Note or change the time at which any Senior Note may or shall be redeemed; (v) make any such series of Senior Notes payable, in money other than that stated in such series of Senior Note; (vi) impair the right to institute suit for the enforcement of any payment of principal of, or premium, if any, or interest on, any Senior Note of such series; (vii) make any change in the percentage of principal amount of Senior Notes necessary to waive compliance with certain provisions of the Indenture; or (viii) waive a continuing Default or Event of Default in the payment of principal of, premium, if any, or interest on such series of the Senior Notes. Each of the Indentures will provide that modifications and amendments of such Indenture may be made by the Company and the Trustee without the consent of any holders of the Senior Notes to which such Indenture relates 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 such 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, or the addition of any Subsidiary of the Company as a Subsidiary Guarantor, in the manner provided in such Indenture, (d) to comply with any requirement of the SEC in order to effect or maintain the qualification of such Indenture under the Trust Indenture Act of 1939 or (e) to make any change that would 39

44 provide any additional benefit to the Holders or that does not adversely affect the rights of any Holder of Senior Notes in any material respect. Each of the Indentures provides that the Holders of a majority in aggregate principal amount of the Senior Notes then outstanding may waive any past default under such 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 Senior Notes of either series ("Legal Defeasance"). Such Legal Defeasance means that the Company will be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Senior Notes of such series, except for (i) the rights of Holders of such Senior Notes to receive payments in respect of the principal of, premium, if any, and interest on such Senior Notes when such payments are due, (ii) the Company's obligations with respect to such Senior Notes concerning the issuance of temporary Senior Notes, transfers and exchanges of such Senior Notes, replacement of mutilated, destroyed, lost or stolen Senior Notes, the maintenance of an office or agency where such Senior Notes may be surrendered for transfer or exchange or presented for payment, and duties of paying agents, (iii) the rights, powers, trusts, duties and immunities of the Trustee, and the Company's obligations in connection therewith and (iv) the Legal Defeasance provisions of the Indenture. In addition, the Company may, at its option and at any time, elect to have the obligations of the Company released with respect to certain covenants described under "-- Certain Covenants" ("Covenant Defeasance"), and thereafter any omission to comply with such obligations shall not constitute a Default or Event of Default with respect to the Senior Notes. In the event Covenant Defeasance occurs, certain events (not including non-payment or bankruptcy and insolvency events) described under "-- Events of Default" will no longer constitute an Event of Default with respect to the Senior Notes. In order to exercise either Legal Defeasance or Covenant Defeasance, (i) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of a series of Senior Notes, cash in U.S. Legal Tender, non-callable 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 Senior Notes of such series 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; (ii) 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 such Indenture, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such opinion of counsel shall confirm that, the Holders of the outstanding Senior Notes of such series will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred; (iii) in the case of Covenant Defeasance, the Company shall have delivered to the Trustee an opinion of counsel reasonably acceptable to the Trustee to the effect that the Holders of the related series of outstanding Senior Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; (iv) no Default or Event of Default shall have occurred and be continuing on the date of such deposit or insofar as Events of Default from bankruptcy or insolvency events are concerned, at any time in the period ending on the 91st day after the date of deposit; (v) such Legal Defeasance or Covenant Defeasance 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; (vi) 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 such series of Senior Notes over other creditors of the Company or with the intent of defeating, hindering, delaying or defrauding creditors of the Company or others; and (vii) the Company shall have delivered to the Trustee an 40

45 Officers' Certificate and an opinion of counsel each stating that all conditions precedent provided for relating to the Legal Defeasance or the Covenant Defeasance have been complied with. GOVERNING LAW Each of the Indentures provides that it will be governed by, and construed in accordance with, the laws of the State of New York, but without giving effect to principles of conflicts of law to the extent that the application of the law of another jurisdiction would be required thereby. THE TRUSTEE United States Trust Company of New York is the Trustee under each of the Indentures. Its address is 114 West 47th Street, New York, New York 10036-1532. The Company has also appointed the Trustee as the initial Registrar, Transfer Agent and Paying Agent under the Indentures. The Trustee is permitted to become an owner or pledgee of Senior 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 of 1939), it must eliminate such conflict or resign. Each of the Indentures provides that 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 either of the Indentures at the request of any of the Holders of the Senior Notes to which such Indenture relates, unless such Holders have offered the Trustee indemnity reasonably satisfactory to it. BOOK-ENTRY SYSTEM Book-Entry, Delivery and Form The certificates representing each of the New Notes due 2004 and the New Notes due 2012 will initially be represented by one or more permanent global Senior Notes in definitive, fully registered form without interest coupons (each a "Global Note") and will be deposited with the Trustee as custodian for, and registered in the name of, a nominee of DTC. Except in the limited circumstances described below under "Certificated Senior Notes," owners of beneficial interests in a Global Note will not be entitled to receive physical delivery of Certificated Senior Notes (as defined below). Ownership of beneficial interests in a Global Note will be limited to persons who have accounts with DTC ("participants") or persons who hold interests through participants. Ownership of beneficial interests in a Global Note will be shown on, and the transfer of that ownership will be effected only through, records maintained by DTC or its nominee (with respect to interests of participants) and the records of participants (with respect to interests of persons other than participants). So long as DTC, or its nominee, is the registered owner or holder of a Global Note, DTC or such nominee, as the case may be, will be considered the sole owner or holder of the Senior Notes represented by such Global Note for all purposes under the applicable Indenture and the Senior Notes. No beneficial owner of an interest in a Global Note will be able to transfer that interest except in accordance with the applicable procedures of DTC, in addition to those provided for under the applicable Indenture. Payments of the principal of, and interest on, a Global Note will be made to DTC or its nominee, as the case may be, as the registered owner thereof. Neither the Company, the Trustee nor any Paying Agent will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in a Global Note or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. The Company expects that DTC or its nominee, upon receipt of any payment of principal or interest in respect of a Global Note, will credit participants' accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of such Global Note as shown on the records of DTC or 41

46 its nominee. The Company also expects that payments by participants to owners of beneficial interests in such Global Note held through such participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers registered in the names of nominees for such customers. Such payments will be the responsibility of such participants. Transfers between participants in DTC will be effected in the ordinary way in accordance with DTC rules and will be settled in same-day funds. The Company expects that DTC will take any action permitted to be taken by a holder of Senior Notes (including the presentation of Senior Notes for exchange as described below) only at the direction of one or more participants to whose account the DTC interests in a Global Note are credited and only in respect of such portion of the aggregate principal amount of Senior Notes as to which such participant or participants has or have given such direction. However, if there is an Event of Default under the Senior Notes, DTC will exchange the applicable Global Note for Certificated Senior Notes, which it will distribute to its participants. The Company understands that DTC is a limited purpose trust company organized under the laws of the State of New York, a "banking organization" within the meaning of New York Banking Law, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the Uniform Commercial Code and a "Clearing Agency" registered pursuant to the provisions of Section 17A under the Exchange Act. DTC was created to hold securities for its participants and facilitate the clearance and settlement of securities transactions between participants through electronic book-entry changes in accounts of its participants, thereby eliminating the need for physical movement of certificates and certain other organizations. Indirect access to the DTC system is available to others such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a participant, either directly or indirectly ("indirect participants"). Although DTC is expected to follow the foregoing procedures in order to facilitate transfers of interests in a Global Note among participants it is under no obligation to perform or continue to perform such procedures, and such procedures may be discontinued at any time. Neither the Company nor the Trustee will have any responsibility for the performance by DTC or its participants or indirect participants of their respective obligations under the rules and procedures governing their operations. Certificated Senior Notes Subject to certain conditions, any person having a beneficial interest in a Global Note may, upon request to the Trustee, exchange such beneficial interest for Senior Notes in the form of certificated Senior Notes ("Certificated Senior Notes"). Upon any such issuance, the Trustee is required to register such Certificated Senior Notes in the name of, and cause the same to be delivered to, such person or persons (or the nominee of any thereof). In addition, if (i) the Company notifies the Trustee in writing that the Depositary is no longer willing or able to act as a depositary and the Company is unable to locate a qualified successor within 90 days or (ii) the Company, at its option, notifies the Trustee in writing that it elects to cause the issuance of Senior Notes in the form of Certificated Senior Notes under the Indentures, then, upon surrender by the Global Note holder of its Global Note, Senior Notes in such form will be issued to each person that the Global Note holder and the Depositary identify as being the beneficial owner of the related Senior Notes. Neither the Company nor the Trustee will be liable for any delay by the Global Note holder or the Depositary in identifying the beneficial owners of Senior Notes and the Company and the Trustee may conclusively rely on, and will be protected in relying on, instructions from the Global Note holder or the Depositary for all purposes. 42

47 PLAN OF DISTRIBUTION There has previously been only a limited secondary market and no public market for the Old Notes. The Company does not intend to apply for the listing of the Senior Notes on a national securities exchange or for their quotation through The Nasdaq Stock Market. The Old Notes are eligible for trading in the PORTAL market. The Company has been advised by the Initial Purchasers that the Initial Purchasers currently intend to make a market in the Senior Notes; however, no Initial Purchaser is obligated to do so and any market making may be discontinued by any Initial Purchaser at any time. In addition, such market making activity may be limited during the Exchange Offer. Therefore, there can be no assurance that an active market for the Old Notes or the New Notes will develop. If a trading market develops for the Old Notes or the New Notes, future trading prices of such securities will depend on many factors, including, among other things, prevailing interest rates, the Company's results of operations and the market for similar securities. Depending on such factors, such securities may trade at a discount from their offering price. With respect to resale of New Notes, based on an interpretation by the staff of the Commission set forth in no-action letters issued to third parties, the Company believes that a holder (other than a person that is an affiliate of the Company within the meaning of Rule 405 under the Securities Act or a "broker" or "dealer" registered under the Exchange Act) who exchanges Old Notes for New Notes in the ordinary course of business and who is not participating, does not intend to participate, and has no arrangement or understanding with any person to participate, in the distribution of the New Notes, will be allowed to resell the New Notes to the public without further registration under the Securities Act and without delivering to the purchasers of the New Notes a prospectus that satisfies the requirements of Section 10 thereof. However, if any holder acquires New Notes in the Exchange Offer for the purpose of distributing or participating in a distribution of the New Notes, such holder cannot rely on the position of the staff of the Commission enunciated in Exxon Capital Holdings Corporation (available May 13, 1988) or similar no-action letters or any similar interpretive letters 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. As contemplated by the above no-action letters and the Registration Rights Agreement, each holder accepting the Exchange Offer is required to represent to the Company in the Letter of Transmittal that (i) the New Notes are to be acquired by the holder in the ordinary course of business, (ii) the holder is not engaging and does not intend to engage in the distribution of the New Notes, and (iii) the holder acknowledges that if such holder participates in the New Offer for the purpose of distributing the New Notes such holder must comply with the registration and prospectus delivery requirements of the Securities Act and cannot rely on the above no-action letters. Any broker or dealer registered under the Exchange Act (each a "Broker-Dealer") who holds Old Notes that were acquired for its own account as a result of market-making activities or other trading activities (other than Old Notes acquired directly from the Company) may exchange such Old Notes for New Notes pursuant to the Exchange Offer; however, such Broker-Dealer may be deemed an underwriter within the meaning of the Securities Act and, therefore, must deliver a prospectus meeting the requirements of the Securities Act in connection with any resales of the New Notes received by it in the Exchange Offer, which prospectus delivery requirement may be satisfied by the delivery by such Broker-Dealer of this Prospectus. The Company and the Subsidiary Guarantors have agreed to cause the Exchange Offer Registration Statement, of which this Prospectus is a part, to remain continuously effective for a period of one year from the date it is first declared effective, and to make this Prospectus, as amended or supplemented, available to any such Broker-Dealer for use in connection with resales. Any Broker-Dealer participating in the Exchange Offer will be required to acknowledge that it will deliver a prospectus in connection with any resales of New Notes received by it in the Exchange Offer. The delivery by a Broker-Dealer of a prospectus in connection with resales of New Notes shall not be deemed to be an admission by such Broker-Dealer that it is an underwriter within the meaning of the Securities Act. The Company will not receive any proceeds from any sale of New Notes by a Broker-Dealer. 43

57 CHESAPEAKE ENERGY CORPORATION AND SUBSIDIARIES CONSOLIDATED STATEMENTS OF CASH FLOWS (CONTINUED) SUPPLEMENTAL SCHEDULE OF NON-CASH INVESTING AND FINANCING ACTIVITIES: The Company has a financing arrangement with a vendor to supply certain oil and gas equipment inventory. The total amounts owed at June 30, 1996, 1995 and 1994 were $3,156,000, $6,513,000 and $5,952,000, respectively. No cash consideration is exchanged for inventory under this financing arrangement until actual draws on the inventory are made. In fiscal 1996 and 1995, the Company recognized income tax benefits of $7,950,000 and $1,229,000, respectively, related to the disposition of stock options by directors and employees of the Company. The tax benefits were recorded as an adjustment to deferred income taxes and paid-in capital. Proceeds from the issuances of $90 million of 10.5% Senior Notes in May 1995 and $120 million of 9.125% Senior Notes in April 1996 are net of $2.7 million and $3.9 million, respectively, in offering fees and expenses which were deducted from the actual cash received. On March 31, 1994, the Company issued 8,000 units (see Note 2) to Trust Company of the West ("TCW") primarily in consideration for the surrender of 576,923 shares of the Company's 9% convertible preferred stock, including its rights to dividends, warrants to purchase Common Stock and an overriding royalty interest. In February 1994, pending litigation was settled pursuant to an agreement requiring COI to pay $1.25 million, of which $250,000 plus interest was paid in July 1994, and the balance of which was paid in June 1995. The accompanying notes are an integral part of these consolidated financial statements. F-7

59 CHESAPEAKE ENERGY CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 1. BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation The accompanying consolidated financial statements of Chesapeake Energy Corporation (the "Company" or "Parent") include the accounts of Chesapeake Operating, Inc. ("COI"), Chesapeake Exploration Limited Partnership ("CEX"), a limited partnership, Chesapeake Gas Development Corporation ("CGDC"), Chesapeake Energy Marketing, Inc. ("CEMI"), Lindsay Oil Field Supply, Inc. ("LOF"), Sander Trucking Company, Inc. ("STCO") and subsidiaries of those entities. All significant intercompany accounts and transactions have been eliminated. In December 1995, the Company entered into the gas marketing business by acquiring all of the outstanding stock of an Oklahoma City-based natural gas marketing company for total consideration of $725,000. This subsidiary was subsequently named CEMI. CEMI provides natural gas marketing services including commodity price structuring, contract administration and nomination services for the Company, its partners and other natural gas producers in the geographical areas in which the Company is active. Accounting Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. Cash Equivalents For purposes of the consolidated financial statements, the Company considers investments in all highly liquid debt instruments with maturities of three months or less at date of purchase to be cash equivalents. Inventory Inventory consists primarily of tubular goods and other lease and well equipment which the Company plans to utilize in its ongoing exploration and development activities and is carried at the lower of cost or market using the specific identification method. Oil and Gas Properties The Company follows the full cost method of accounting under which all costs associated with property acquisition, exploration and development activities are capitalized. The Company capitalizes internal costs that can be directly identified with its acquisition, exploration and development activities and does not include any costs related to production, general corporate overhead or similar activities (see Note 11). Capitalized costs are amortized on a composite unit-of-production method based on proved oil and gas reserves. The Company's oil and gas reserves are estimated annually by independent petroleum engineers. The average composite rates used for depreciation, depletion and amortization were $0.85, $0.80 and $0.80 per equivalent Mcf in 1996, 1995, and 1994, respectively. Proceeds from the sale of properties are accounted for as reductions to capitalized costs unless such sales involve a significant change in the relationship between costs and the value of proved reserves or the underlying value of unproved properties, in which case a gain or loss is recognized. Unamortized costs as reduced by related deferred taxes are subject to a ceiling which limits such amounts to the estimated present value of oil and gas reserves, reduced by operating expenses, future development costs and income taxes. The costs of unproved properties are excluded from amortization until the properties are evaluated. F-9

60 CHESAPEAKE ENERGY CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) On April 30, 1996, the Company purchased interests in certain producing and non-producing oil and gas properties, including approximately 14,000 net acres of unevaluated leasehold from Amerada Hess Corporation for $35 million, subject to adjustment for activity after the effective date of January 1, 1996. The properties are located in the Knox and Golden Trend fields of southern Oklahoma, most of which are operated by the Company. Other Property and Equipment Other property and equipment primarily consists of vehicles, office buildings and equipment, and software. Major renewals and betterments are capitalized while the costs of repairs and maintenance are charged to expense as incurred. The costs of assets retired or otherwise disposed of and the applicable accumulated depreciation are removed from the accounts, and the resulting gain or loss is reflected in operations. Other property and equipment costs are depreciated on both straight-line and accelerated methods over the estimated useful lives of the assets, which range from three to 30 years. Leases Included in other property and equipment in the consolidated balance sheets is computer equipment and software held under capital leases. Minimum lease payments under these capital leases and other operating leases are as follows: CAPITAL OPERATING LEASES LEASES ------- --------- ($ IN THOUSANDS) 1997...................................................... $ 62 $133 1998...................................................... 62 58 1999...................................................... 15 53 2000...................................................... 0 0 2001...................................................... 0 0 ---- ---- Total minimum lease payments.............................. 139 $244 ==== Less: amount relating to interest......................... (20) ---- Present value of minimum payments......................... $119 ==== Capitalized Interest During fiscal 1996, 1995 and 1994, interest of approximately $6,428,000, $1,574,000 and $356,000 was capitalized on significant investments in unproved properties that are not being currently depreciated, depleted, or amortized and on which exploration or development activities are in progress. Service Operations Certain subsidiaries of the Company performed contractual services on wells the Company operates as well as for third parties until June 30, 1996. Oil and gas service operations revenues and costs and expenses reflected in the accompanying consolidated statements of income include amounts derived from certain of the contractual services provided. The Company's economic interest in its oil and gas properties is not affected by the performance of these contractual services and all intercompany profits have been eliminated. On June 30, 1996, Peak USA Energy Services, Ltd., a limited partnership ("Peak"), was formed by Peak Oilfield Services Company (a joint venture between Cook Inlet Region, Inc. and Nabors Industries, Inc.) and Chesapeake for the purpose of purchasing the Company's oilfield service assets and providing rig moving, transportation and related site construction services to the Company and the industry. The Company sold its F-10

61 CHESAPEAKE ENERGY CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) service company assets to Peak for $6.4 million, and simultaneously invested $2.5 million in exchange for a 33.3% partnership interest in Peak. This transaction resulted in recognition of a $1.8 million pre-tax gain during the fourth fiscal quarter of 1996 reported in Interest and other. A deferred gain from the sale of service company assets of $0.9 million was recorded as a reduction in the Company's investment in Peak and will be amortized to income over the estimated useful lives of the Peak assets. The Company's investment in Peak will be accounted for using the equity method. Income Taxes The Company has adopted Statement of Financial Accounting Standards No. 109, "Accounting for Income Taxes" ("SFAS 109"). SFAS 109 requires deferred tax liabilities or assets to be recognized for the anticipated future tax effects of temporary differences that arise as a result of the differences in the carrying amounts and the tax bases of assets and liabilities. Net Income Per Share Primary and fully diluted earnings per share for all periods have been computed based upon the weighted average number of shares of Common Stock outstanding after giving retroactive effect to all stock splits and the issuance of common stock equivalents when their effect is dilutive. Dilutive options or warrants which are issued during a period or which expire or are cancelled during a period are reflected in both primary and fully diluted earnings per share computations for the time they were outstanding during the period being reported upon. Gas Imbalances The Company follows the "sales method" of accounting for its oil and gas revenue whereby the Company recognizes sales revenue on all oil or gas sold to its purchasers, regardless of whether the sales are proportionate to the Company's ownership in the property. A liability is recognized only to the extent that the Company has a net imbalance in excess of the reserves on the underlying properties. The Company's net imbalance positions at June 30, 1996 and 1995 were not material. Hedging The Company periodically uses certain instruments to hedge its exposure to price fluctuations on oil and natural gas transactions. Recognized gains and losses on hedge contracts are reported as a component of the related transaction. Results for hedging transactions are reflected in oil and gas sales to the extent related to the Company's oil and gas production. Debt Issue Costs Other assets relate primarily to debt issue costs associated with the issuance of the 12% Senior Notes on March 31, 1994, the 10.5% Senior Notes on May 25, 1995, and the 9.125% Senior Notes on April 9, 1996 (see Note 2). The remaining unamortized costs on these issuances of Senior Notes at June 30, 1996 totaled $8.7 million and are being amortized over the life of the Senior Notes. Stock Options In October 1995, the Financial Accounting Standards Board issued Statement No. 123 ("SFAS 123"), "Accounting for Stock Based Compensation". As permitted by SFAS 123, the Company plans to continue to retain its current method of accounting for stock compensation and adopt the disclosure requirements of this Statement in fiscal 1997. F-11

62 CHESAPEAKE ENERGY CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) Reclassifications Certain reclassifications have been made to the consolidated financial statements for the years ended June 30, 1995 and 1994 to conform to the presentation used for the June 30, 1996 consolidated financial statements. 2. SENIOR NOTES On April 9, 1996, the Company completed an offering of $120 million principal amount of 9.125% Senior Notes due 2006 ("9.125% Senior Notes"). The 9.125% Senior Notes are redeemable at the option of the Company at any time at the redemption or make-whole prices set forth in the indenture. The Company may also redeem at its option at any time on or prior to April 15, 1999 up to $42 million of the 9.125% Senior Notes at 109.125% of the principal amount thereof with the proceeds of an equity offering. On May 25, 1995, the Company completed a private offering of $90 million principal amount of 10.5% Senior Notes due 2002 ("10.5% Senior Notes"). The 10.5% Senior Notes are redeemable at the option of the Company at any time on or after June 1, 1999. The Company may also redeem at its option any time prior to June 1, 1998 up to $30 million of the 10.5% Senior Notes at 110% of the principal amount thereof with the proceeds of an equity offering. In September 1995, the Company exchanged the 10.5% Senior Notes for substantially identical notes in a registered exchange offer (also referred to as the "10.5% Senior Notes"). On March 31, 1994, the Company completed a private offering of 47,500 Units consisting of an aggregate of $47.5 million principal amount of 12% Senior Notes due 2001 ("12% Senior Notes") and warrants ("Warrants") to purchase 4,381,874 shares of the Company's Common Stock at an aggregate exercise price of $4,870. The Warrants were valued at $3 million creating a discount on the 12% Senior Notes. All of the Warrants were subsequently exercised. In exchange for 8,000 Units, the Company acquired from Trust Company of the West ("TCW") 576,923 shares of the Company's 9% cumulative convertible preferred stock and all rights to dividends thereon, warrants to purchase 2,808,008 shares of the Company's Common Stock and 50% of an outstanding overriding royalty interest held by TCW. The 12% Senior Notes are redeemable at the option of the Company at any time on or after March 1, 1998 at an initial premium of 106% of the principal amount thereof, declining to no premium in 2000. The Company is required to redeem $11,875,000 principal amount of 12% Senior Notes on each of March 1, 1998, 1999 and 2000. In November 1994, the Company exchanged the 12% Senior Notes for substantially identical notes in a registered exchange offer (also referred to as the "12% Senior Notes"). The Company is a holding company and owns no operating assets and has no significant operations independent of its subsidiaries. The Company's obligations under the 12% Senior Notes, the 10.5% Senior Notes and the 9.125% Senior Notes have been fully and unconditionally guaranteed, on a joint and several basis, by each of the Company's "Restricted Subsidiaries" (as defined in the respective Indentures governing the Notes): COI, LOF, STCO, Whitmire Dozer Service, Inc. and CEX (collectively, the "Subsidiary Guarantors"). The only subsidiaries of the Company that are not Subsidiary Guarantors are CGDC and CEMI (together, the "Non-Guarantor Subsidiaries"). Each of the Subsidiary Guarantors is a direct or indirect wholly-owned subsidiary of the Company. The securities of the Subsidiary Guarantors have been pledged to secure performance of the Company's obligations under the 12% Senior Notes. The only affiliate securities constituting a substantial portion of the collateral for the 12% Senior Notes are the partnership interests in CEX. The 12%, 10.5% and 9.125% Senior Note Indentures contain certain covenants, including covenants limiting the Company and the Subsidiary Guarantors with respect to asset sales; restricted payments; the incurrence of additional indebtedness and the issuance of preferred stock; liens; sale and leaseback transactions; lines of business; dividend and other payment restrictions affecting Subsidiary Guarantors; mergers or consolidations; and transactions with affiliates. The Company is also obligated to repurchase 12%, F-12

63 CHESAPEAKE ENERGY CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) 10.5% and 9.125% Senior Notes if it fails to maintain a specified ratio of assets to debt and in the event of a change of control or certain asset sales. The Company's bank credit agreement prohibits any distributions by CEX to its partners (the Company and COI) if the maturity of any obligations to the lender has been accelerated. The pledge agreement relating to the 12% Senior Notes requires that all dividends and distributions from Subsidiary Guarantors be paid to the collateral agent thereunder upon an event of default under the 12% Senior Notes Indenture. There are no other restrictions on the payment of cash dividends by Subsidiary Guarantors. CEX is a limited partnership which is 10% owned by COI, as sole general partner, and 90% owned directly by the Company, as sole limited partner. CEX owns 94% and CGDC owns 6% of the Company's producing oil and gas properties, based on the present value of future net revenue at June 30, 1996 (discounted at 10%). Set forth below are condensed consolidating financial statements of CEX, the other Subsidiary Guarantors, all Subsidiary Guarantors combined, the Non-Guarantor Subsidiaries and the Company. The CEX limited partnership condensed financial statements were prepared on a separate entity basis as reflected in the Company's books and records and include all material costs of doing business as if the partnership were on a stand-alone basis except that interest is not charged or allocated. No provision has been made for income taxes because the partnership is not a taxpaying entity. Separate audited financial statements of each Subsidiary Guarantor, other than CEX, have not been provided because management has determined that they are not material to investors. F-13

The Revolving Credit Facility has been amended from time to F-18

69 CHESAPEAKE ENERGY CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) time, most recently in September 1996. Concurrent with the September 1996 amendment, the Company increased the facility size to $125 million and expanded its bank group with Union Bank remaining as agent. The maturity date of the Revolving Credit Facility is April 30, 2001. The facility provides for interest at the Union Bank reference rate (8.25% at June 30, 1996) or, at the option of the Company the Eurodollar rate plus 1.375% to 1.875% depending on the ratio of the amount outstanding to the borrowing base. Borrowings are collateralized by a first priority lien on substantially all of CEX's proved producing reserves, and are unconditionally guaranteed by the Company. At June 30, 1996 and 1995 there was $0 and $10,000 outstanding under the Revolving Credit Facility, respectively. The amount of credit available at any time under the Revolving Credit Facility is the lesser of the commitment amount or the borrowing base. The borrowing base is reduced each month by a specified amount. Both the borrowing base and the monthly reduction amount are redetermined by Union Bank each May 1 and November 1 and may be redetermined at any other time upon the request of CEX or Union Bank. To the extent the amount outstanding at any time exceeds the borrowing base, CEX must reduce the amount outstanding or add additional collateral. At June 30, 1996, the commitment amount and the borrowing base under the Revolving Credit Facility were $35 million, and the monthly reduction amount was $700,000. The Revolving Credit Facility was amended in September 1996 to provide for a borrowing base and a commitment amount of $75 million, with a monthly reduction amount of $1,750,000. The Revolving Credit Facility contains customary financial covenants, limitations on indebtedness and liabilities, liens, prepayments of other indebtedness (including the 12%, 10.5% and 9.125% Senior Notes) and loans, investments and guarantees by the Company and prohibits the payment of dividends on the Company's Common Stock. The Company's wholly-owned subsidiary, CGDC, has a credit facility with Union Bank (the "Term Credit Facility"), with an outstanding balance of $12.9 million at June 30, 1996. Collateral for the Term Credit Facility is limited to CGDC's producing oil and gas properties. The Term Credit Facility has not been guaranteed by the Company or any of its other subsidiaries and is recourse only to the assets of CGDC. CGDC acquired producing oil and gas properties from CEX in December 1994, June 1995 and December 1995 in exchange for $5.5 million, $6 million and $5.3 million in cash, respectively, using proceeds borrowed under this facility. CGDC has not guaranteed the payment of the Company's 12%, 10.5% or 9.125% Senior Notes, nor has the capital stock of CGDC been pledged as collateral for such indebtedness. The terms of the Term Credit Facility prohibit the payment of dividends by CGDC. 4. CONTINGENCIES AND COMMITMENTS The Company is currently involved in various routine disputes incidental to its business operations. While it is not possible to determine the ultimate disposition of these matters, management, after consultation with legal counsel, is of the opinion that the final resolution of all currently pending or threatened litigation is not likely to have a material adverse effect on the consolidated financial position or results of operations of the Company. The Company has employment contracts with its two principal shareholders and its chief financial officer and various other senior management personnel which provide for annual base salaries, bonus compensation and various benefits. The contracts provide for the continuation of salary and benefits for the respective terms of the agreements in the event of termination of employment without cause. These agreements expire June 30, 1997 through June 30, 1998. Due to the nature of the oil and gas business, the Company and its subsidiaries are exposed to possible environmental risks. The Company has implemented various policies and procedures to avoid environmental contamination and risks from environmental contamination. The Company is not aware of any potential environmental issues or claims. F-19

70 CHESAPEAKE ENERGY CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) 5. INCOME TAXES As discussed in Note 1, the Company has adopted SFAS 109. The components of the income tax provision for each of the periods are as follows: YEAR ENDED JUNE 30, --------------------------- 1996 1995 1994 ------- ------ ------ ($ IN THOUSANDS) Current................................................. $ -- $ -- $ -- Deferred................................................ 12,854 6,299 1,250 ------- ------ ------ Total......................................... $12,854 $6,299 $1,250 ======= ====== ====== The effective income tax rate differed from the computed "expected" federal income tax rate on earnings before income taxes for the following reasons: YEAR ENDED JUNE 30, --------------------------- 1996 1995 1994 ------- ------ ------ ($ IN THOUSANDS) Computed "expected" income tax provision................ $12,673 $6,286 $1,753 Tax percentage depletion................................

The tax effected temporary differences and tax loss carryforwards which comprise deferred taxes are as follows: YEAR ENDED JUNE 30, -------------------------------- 1996 1995 1994 -------- -------- -------- ($ IN THOUSANDS) Deferred tax liabilities: Acquisition, exploration and development costs and related depreciation, depletion and amortization..................................... $(63,725) $(31,220) $(15,872) -------- -------- -------- Deferred tax assets: Net operating loss carryforwards................... 50,776 23,414 12,879 Percentage depletion carryforward.................. 764 526 780 -------- -------- -------- 51,540 23,940 13,659 -------- -------- -------- Total Deferred Income Taxes........................ $(12,185) $ (7,280) $ (2,213) ======== ======== ======== At June 30, 1996, the Company had regular tax net operating loss carryforwards of approximately $140 million and alternative minimum tax net operating loss carryforwards of approximately $15 million. These loss carryforward amounts will expire during the years 2007 through 2011. The Company also had a percentage depletion carryforward of approximately $2.3 million at June 30, 1996, which is available to offset future federal income taxes payable and has no expiration date. In accordance with certain provisions of the Tax Reform Act of 1986, a change of greater than 50% of the beneficial ownership of the Company within a three-year period (an "Ownership Change") would place an annual limitation on the Company's ability to utilize its existing tax carryforwards. Under regulations issued by F-20

71 CHESAPEAKE ENERGY CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) the Internal Revenue Service, the Company does not believe that an Ownership Change has occurred as of June 30, 1996. 6. RELATED PARTY TRANSACTIONS Certain directors, shareholders and employees of the Company have acquired working interests in certain of the Company's oil and gas properties. The owners of such working interests are required to pay their proportionate share of all costs. As of June 30, 1996, 1995 and 1994 the Company had accounts receivable for these costs of $2.9 million, $4.4 million and $1.7 million, respectively. During fiscal 1996, 1995 and 1994 the Company incurred legal expenses of $347,000, $516,000 and $631,000, respectively, for legal services provided by the law firm of which a director is a member. 7. EMPLOYEE BENEFIT PLANS Effective October 1, 1989, the Company established a 401(K) profit sharing plan. On December 1, 1993, the Company amended the plan and established the Chesapeake Energy Savings and Incentive Plan. On January 1, 1996 the Company amended the plan and established the Chesapeake Energy Corporation Savings and Incentive Stock Bonus Plan (the "Savings and Incentive Stock Bonus Plan"). Eligible employees may make voluntary contributions to the Savings and Incentive Stock Bonus Plan which are matched by the Company up to 10% of the employees' annual salary with the Company's common stock. The amount of employee contributions is limited as specified in the Savings and Incentive Stock Bonus Plan. The Company may, at its discretion, make additional contributions to the Savings and Incentive Stock Bonus Plan. The Company contributed $187,000, $95,000 and $70,000 to the Savings and Incentive Stock Bonus Plan during the fiscal years ended June 30, 1996, 1995 and 1994, respectively. 8. MAJOR CUSTOMERS Sales to individual customers constituting 10% or more of total oil and gas sales were as follows: PERCENT OF YEAR AMOUNT OIL AND GAS SALES - ---- ---------------- ----------------- ($ IN THOUSANDS) 1996 Aquila Southwest Pipeline Corporation $41,900 38% GPM Gas Corporation $28,700 26% Wickford Energy Marketing, L.C. $18,500 17% 1995 Aquila Southwest Pipeline Corporation $18,548 33% Wickford Energy Marketing, L.C. $15,704 28% GPM Gas Corporation $11,686 21% 1994 Wickford Energy Marketing, L.C. $ 6,190 28% GPM Gas Corporation $ 6,105 27% Plains Marketing and Transportation, Inc. $ 2,659 12% Texaco Exploration & Production, Inc. $ 2,249 10% Management believes that the loss of any of the above customers would not have a material impact on the Company's results of operations or its financial position. 9. STOCKHOLDERS' EQUITY Effective December 31, 1996, the Company changed its state of incorporation from Delaware to Oklahoma. As part of this transaction, the authorized capital stock of the Company was increased to 100,000,000 shares of common stock, par value $.01 per share, and 10,000,000 shares of preferred stock, par F-21

72 CHESAPEAKE ENERGY CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) value $.01 per share. Also effective December 31, 1996, the Company effected a 2-for-1 split of its common stock. All par value, share and per share information, common stock options and exercise prices included in these consolidated financial statements and related footnotes have been restated to reflect the stock split. On April 9, 1996, the Company completed a public offering of 4,950,000 shares of Common Stock at a price of $17.67 per share, resulting in net proceeds (after offering costs) to the Company of approximately $82.1 million. On April 12, 1996, the underwriters exercised an over-allotment option to purchase an additional 1,039,500 shares of Common Stock at a price of $17.67 per share, resulting in additional net proceeds (after offering costs) to the Company of approximately $17.3 million. The net proceeds from the offering were used to fund a portion of the Company's exploration and development capital expenditures and for general corporate purposes. On March 31, 1994, the Company issued 12% Senior Notes and Warrants for 4,381,874 shares of the Company's Common Stock (see Note 2). The Warrants were valued at $3.04 million and are recorded as Common Stock Warrants and paid-in capital on the accompanying consolidated balance sheets. A portion of the 12% Senior Notes and Warrants were issued to Trust Company of the West in exchange for preferred stock, warrants to purchase Common Stock and an overriding royalty interest. A 1.8-for-1 stock split of the Common Stock in January 1993, a 2-for-1 stock split of the Common Stock in December 1994, and 3-for-2 stock splits of the Common Stock in December 1995 and June 1996 have been given retroactive effect in these financial statements.

During fiscal 1996 and 1995, $7,950,000 and $1,229,000 was recorded as an adjustment to additional paid-in capital and deferred income taxes with respect to such tax benefits. 10. FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES The Company has only limited involvement with derivative financial instruments, as defined in Statement of Financial Accounting Standards No. 119 "Disclosure About Derivative Financial Instruments and Fair Value of Financial Instruments" and does not use them for trading purposes. The Company's objective is to hedge a portion of its exposure to price volatility from producing crude oil and natural gas. These arrangements may expose the Company to credit risk from its counter-parties and to basis risk. Hedging Activities Periodically the Company utilizes hedging strategies to hedge the price of a portion of its future oil and gas production. These strategies include swap arrangements that establish an index-related price above which the Company pays the hedging partner and below which the Company is paid by the hedging partner, the purchase of index-related puts that provide for a "floor" price to the Company to be paid by the counter-party to the extent the price of the commodity is below the contracted floor, and basis protection swaps. As of June 30, 1996, the Company had established NYMEX-based crude oil swap agreements for 1,000 Bbl per day for July 1, 1996 through August 31, 1996 at an average price of $17.85 per Bbl. The counter-party has the option exercisable monthly for an additional 1,000 Bbl per day for the period July 1, 1996 through December 31, 1996 to cause a swap if the price exceeds an average $17.74 per Bbl. The actual settlements for July and August resulted in a $0.5 million payment to the counter-party. The Company estimates, based on NYMEX prices as of August 30, 1996, that the effect of the September through December hedges would be a $0.4 million payment to the counter-party. The Company has purchased Houston Ship Channel put options which guarantee the Company an average floor price of $2.21/Mmbtu for 20,000 Mmbtu per day for the period of November 1, 1996 through February 28, 1997. The average cost of these puts was $0.14 per Mmbtu. As of June 30, 1996, the Company had NYMEX-based natural gas swaps and NYMEX/Houston Ship Channel Basis swaps for the months of July through October 1996. These transactions resulted in payments to F-23

74 CHESAPEAKE ENERGY CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) the Company's counter-party of approximately $2 million for the month of July 1996 and $1.5 million for the month of August 1996. The Company estimates, based on NYMEX prices as of August 30, 1996, that the effect of the September and October hedges would be a $0.2 million payment to the counter-party. Concentration of Credit Risk Financial instruments which potentially subject the Company to concentrations of credit risk consist principally of trade receivables. The Company's accounts receivable are primarily from purchasers of oil and natural gas products and exploration and production companies which own interests in properties operated by the Company. The industry concentration has the potential to impact the Company's overall exposure to credit risk, either positively or negatively, in that the customers may be similarly affected by changes in economic, industry or other conditions. The Company generally requires letters of credit for receivables from customers which are not considered investment grade, unless the credit risk can otherwise be mitigated. Fair Value of Financial Instruments The following disclosure of the estimated fair value of financial instruments is made in accordance with the requirements of Statement of Financial Accounting Standards No. 107, "Disclosures About Fair Value of Financial Instruments." The estimated fair value amounts have been determined by the Company using available market information and valuation methodologies. Considerable judgment is required in interpreting market data to develop the estimates of fair value. The use of different market assumptions or valuation methodologies may have a material effect on the estimated fair value amounts. The carrying values of items comprising current assets and current liabilities approximate fair values due to the short-term maturities of these instruments. The Company estimates the fair value of its long-term, fixed-rate debt using quoted market prices. The Company's carrying amount for such debt at June 30, 1996 and 1995 was $255.6 million and $135.2 million, respectively, compared to approximate fair values of $261.2 million and $137.8 million, respectively. The carrying value of other long-term debt approximates its fair value as interest rates are primarily variable, based on prevailing market rates. 11. DISCLOSURES ABOUT OIL AND GAS PRODUCING ACTIVITIES Net Capitalized Costs Evaluated and unevaluated capitalized costs related to the Company's oil and gas producing activities are summarized as follows: JUNE 30, -------------------- 1996 1995 -------- -------- ($ IN THOUSANDS) Oil and gas properties: Proved.................................................... $363,213 $165,302 Unproved.................................................. 165,441 27,474 -------- -------- Total............................................. 528,654 192,776 Less accumulated depreciation, depletion and amortization...

The Company capitalized approximately $6,428,000 and $1,574,000 of interest during the years ended June 30, 1996 and 1995 on significant investments in unproved properties that are not being currently depreciated, depleted, or amortized and on which exploration or development activities are in progress. The Company will continue to evaluate its unevaluated properties; however, the timing of the ultimate evaluation and disposition of the properties has not been determined. F-24

The following table includes revenues and expenses associated directly with the Company's oil and gas producing activities. It does not include any allocation of the Company's interest costs and, therefore, is not necessarily indicative of the contribution to consolidated net operating results of the Company's oil and gas operations.

Oil and Gas Reserve Quantities (unaudited) The reserve information presented below is based upon reports prepared by the independent petroleum engineering firm of Williamson Petroleum Consultants, Inc. ("Williamson") as of June 30, 1996, 1995 and 1994 and the Company's petroleum engineers as of June 30, 1996 and 1995. The reserves evaluated internally by the Company constituted approximately 0.6% and 0.5% of total proved reserves as of June 30, 1996 and 1995, respectively. The information is presented in accordance with regulations prescribed by the Securities and Exchange Commission. The Company emphasizes that reserve estimates are inherently imprecise. The Company's reserve estimates were generally based upon extrapolation of historical production trends, analogy F-25

76 CHESAPEAKE ENERGY CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) to similar properties and volumetric calculations. Accordingly, these estimates are expected to change, and such changes could be material, as future information becomes available. Proved oil and gas reserves represent the estimated quantities of crude oil, natural gas, and natural gas liquids which geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions. Proved developed oil and gas reserves are those expected to be recovered through existing wells with existing equipment and operating methods. Presented below is a summary of changes in estimated reserves of the Company based upon the reports prepared by Williamson for 1996, 1995 and 1994, along with those prepared by the Company's petroleum engineers for 1996 and 1995: JUNE 30, ------------------------------------------------------ 1996 1995 1994 ---------------- ---------------- ---------------- OIL GAS OIL GAS OIL GAS (MBBL) (MMCF) (MBBL) (MMCF) (MBBL) (MMCF) ------ ------- ------ ------- ------ ------- Proved reserves, beginning of year........................ 5,116 211,808 4,154 117,066 9,622 79,763 Extensions, discoveries and other additions............. 8,924 173,577 2,345 129,444 2,335 82,965 Revisions of previous estimate....................

The properties are located in the Knox and Golden Trend fields of southern Oklahoma, most of which are operated by the Company. In October 1993, the Company entered into a joint development agreement covering a 20,000 gross acre development area in the Fayette County portion of the Giddings Field in southern Texas. The Company's ownership interests in the proved undeveloped properties covered by the joint development agreement were significantly less than those used in the June 30, 1993 reserve report. The impact of the reduced ownership percentages is reflected as sales of reserves in place in fiscal 1994 in the preceding table. Standardized Measure of Discounted Future Net Cash Flows (unaudited) Statement of Financial Accounting Standards No. 69 ("SFAS 69") prescribes guidelines for computing a standardized measure of future net cash flows and changes therein relating to estimated proved reserves. The Company has followed these guidelines which are briefly discussed below. Future cash inflows and future production and development costs are determined by applying year-end prices and costs to the estimated quantities of oil and gas to be produced. Estimates are made of quantities of proved reserves and the future periods during which they are expected to be produced based on year-end economic conditions. Estimated future income taxes are computed using current statutory income tax rates including consideration for the current tax basis of the properties and related carryforwards, giving effect to F-26

77 CHESAPEAKE ENERGY CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) permanent differences and tax credits. The resulting future net cash flows are reduced to present value amounts by applying a 10% annual discount factor. The assumptions used to compute the standardized measure are those prescribed by the Financial Accounting Standards Board and, as such, do not necessarily reflect the Company's expectations of actual revenue to be derived from those reserves nor their present worth. The limitations inherent in the reserve quantity estimation process, as discussed previously, are equally applicable to the standardized measure computations since these estimates are the basis for the valuation process. The following summary sets forth the Company's future net cash flows relating to proved oil and gas reserves based on the standardized measure prescribed in SFAS 69: JUNE 30, -------------------------------- 1996 1995 1994 ---------- -------- -------- ($ IN THOUSANDS) Future cash inflows................................. $1,101,642 $427,377 $307,600 Future production costs.............................

85 CHESAPEAKE EXPLORATION LIMITED PARTNERSHIP (A WHOLLY-OWNED PARTNERSHIP OF CHESAPEAKE ENERGY CORPORATION) NOTES TO FINANCIAL STATEMENTS 1. BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Chesapeake Exploration Limited Partnership, an Oklahoma limited partnership ("CEX"), was formed on December 27, 1994 and acquired Chesapeake Exploration Company ("Exploration") by merger on such date. Exploration was a general partnership which was 10% owned by Chesapeake Operating, Inc. ("COI") and 90% owned by Chesapeake Energy Corporation ("CEC" or the "Company"). CEC owns 100% of the Common Stock of COI. CEX is 10% owned by COI as the sole general partner, and 90% owned directly by the Company, as the sole limited partner. Effective December 31, 1994, COI transferred to CEX all of the Company's undeveloped leasehold acreage, thereby formalizing their prior economic arrangement. Historically, COI had transferred undeveloped leasehold acreage to CEX on a property-by-property basis as drilling commenced. CEX also owns substantially all of the Company's proved developed oil and gas properties. Accordingly, the financial statements of CEX include costs related to proved undeveloped properties and unevaluated properties, as well as proved producing properties. The change in partnership structure and the transfer of undeveloped leasehold by COI to CEX have been accounted for as a reorganization of entities under common control in a manner similar to a pooling-of-interests. The CEX financial statements were prepared on a separate entity basis as reflected in the Company's books and records and include all material costs of doing business as if the partnership were on a stand-alone basis, except that interest is not charged on intercompany accounts, or allocated. Capital is provided by advances from CEC and COI, and to a lesser extent directly by CEX's bank credit facilities. These financial statements should be read in conjunction with CEC's consolidated financial statements. Accounting Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. Oil and Gas Properties CEC, and therefore CEX, follows the full cost method of accounting under which all costs associated with property acquisition, exploration and development activities are capitalized. CEX capitalizes internal costs that can be directly identified with its acquisition, exploration and development activities. Such costs do not include any costs related to production, general corporate overhead or similar activities (see Note 7). Capitalized costs are amortized on a composite unit-of-production method based on proved oil and gas reserves. CEX's oil and gas reserves are estimated annually by independent petroleum engineers. The average composite rates used for depreciation, depletion and amortization were $.85, $.80 and $.80 per equivalent Mcf in 1996, 1995 and 1994, respectively. Proceeds from the sale of properties are accounted for as reductions to capitalized costs unless such sales involve a significant change in the relationship between costs and the value of proved reserves or the underlying value of unproved properties, in which case a gain or loss is recognized. Unamortized costs, as reduced by related deferred taxes, are subject to a ceiling which limits such amounts to the estimated present value of oil and gas reserves, reduced by operating expenses, future development costs and income taxes. The costs of unproved properties are excluded from amortization until the properties are evaluated. F-35

86 CHESAPEAKE EXPLORATION LIMITED PARTNERSHIP (A WHOLLY-OWNED PARTNERSHIP OF CHESAPEAKE ENERGY CORPORATION) NOTES TO FINANCIAL STATEMENTS -- (CONTINUED) On April 30, 1996, CEX purchased interests in certain producing and non-producing oil and gas properties, including approximately 14,000 net acres of unevaluated leasehold, from Amerada Hess Corporation for $35 million, subject to adjustment for activity after the effective date of January 1, 1996. The properties are located in the Knox and Golden Trend fields of southern Oklahoma, most of which are operated by the Company. Capitalized Interest During fiscal 1996, 1995 and 1994, interest of approximately $6,428,000, $1,574,000 and $356,000 was capitalized on significant investments in unproved properties that are not being currently depreciated, depleted, or amortized and on which exploration or development activities are in progress. Intercompany Transactions COI, as operator of the majority of CEX's producing properties, bills CEX, as non-operator, on a monthly basis for services performed as operator pursuant to a standard operating agreement which is common in the industry. Expenses related to the operations of CEX are recorded via such joint interest billings and via intercompany expense allocations to CEX by COI. CEX has no employees. In the CEC consolidated group, COI employs all management personnel and employees, except for employees of the service company subsidiaries, and the preponderance of general and administrative expenses are reflected in the financial records of COI. COI allocates a portion of its general and administrative expenses to CEX each period. This allocation is based on a per well charge at a rate common in the industry plus an estimate of time spent on CEX activities by officers and employees of COI. CEC makes advances to CEX as needed. Certain of CEC's service subsidiaries perform contractual services on CEX's wells for third parties. These subsidiaries bill COI, as operator, and COI in turn bills CEX through monthly joint interest billings in accordance with the terms of the standard operating agreement. It is CEC's policy not to demand payment of intercompany accounts. Interest is not allocated by the Company, nor is interest charged on intercompany accounts. CEC may, at its discretion, but it is not required to, contribute intercompany accounts to capital. Income Taxes CEX is a partnership and, accordingly, its taxable income or loss is allocated to the limited partner and the general partner and is ultimately included in CEC's consolidated tax returns. Gas Imbalances CEX follows the "sales method" of accounting for its oil and gas revenue whereby CEX recognizes sales revenue on all oil or gas sold to its purchasers, regardless of whether the sales are proportionate to CEX's ownership in the property. A liability is recognized only to the extent that CEX has a net imbalance in excess of the reserves on the underlying properties. CEX's net imbalance positions at June 30, 1996 and 1995 were not material. Hedging The Company, on behalf of CEX, periodically uses certain instruments to hedge its exposure to price fluctuations on oil and natural gas transactions. Recognized gains and losses on hedge contracts are reported as a component of the related transaction. Results for hedging transactions are reflected in oil and gas sales to the extent related to CEX's oil and gas production. F-36

87 CHESAPEAKE EXPLORATION LIMITED PARTNERSHIP (A WHOLLY-OWNED PARTNERSHIP OF CHESAPEAKE ENERGY CORPORATION) NOTES TO FINANCIAL STATEMENTS -- (CONTINUED) Reclassifications Certain reclassifications have been made to the CEX financial statements for the years ended June 30, 1995 and 1994 to conform to the presentation used for the June 30, 1996 financial statements. 2. LONG-TERM DEBT In April 1993, CEX entered into an oil and gas reserve-based reducing revolving credit facility (the "Revolving Credit Facility") with Union Bank. The Revolving Credit Facility has been amended from time to time, most recently in September 1996. Concurrent with the September 1996 amendment, CEX increased the facility size to $125 million and expanded its bank group with Union Bank remaining as agent. The maturity date of the Revolving Credit Facility is April 30, 2001. The facility provides for interest at the Union Bank reference rate (8.25% at June 30, 1996) or, at the option of CEX the Eurodollar rate plus 1.375% to 1.875% depending on the ratio of the amount outstanding to the borrowing base. Borrowings are collateralized by a first priority lien on substantially all of CEX's proved producing reserves, and are unconditionally guaranteed by the Company. At June 30, 1996 and 1995 there was $0 and $10,000 outstanding under the Revolving Credit Facility, respectively. The amount of credit available at any time under the Revolving Credit Facility is the lesser of the commitment amount or the borrowing base. The borrowing base is reduced each month by a specified amount. Both the borrowing base and the monthly reduction amount are redetermined by Union Bank each May 1 and November 1 and may be redetermined at any other time upon the request of CEX or Union Bank. To the extent the amount outstanding at any time exceeds the borrowing base, CEX must reduce the amount outstanding or add additional collateral. At June 30, 1996, the commitment amount and the borrowing base under the Revolving Credit Facility were $35 million, and the monthly reduction amount was $700,000. The Revolving Credit Facility was amended in September 1996 to provide for a borrowing base and a commitment amount of $75 million, with a monthly reduction amount of $1,750,000. The Revolving Credit Facility contains customary financial covenants, limitations on indebtedness and liabilities, liens, prepayments of other indebtedness and loans, investments and guarantees by the Company and prohibits the payment of dividends on the Company's Common Stock. 3. CONTINGENCIES AND COMMITMENTS CEX has fully and unconditionally guaranteed CEC's obligations under the $47.5 million principal amount of 12% Senior Notes due 2001, issued March 31, 1994, the $90 million principal amount of 10.5% Senior Notes due 2002, issued May 25, 1995, and the $120 million principal amount of 9.125% Senior Notes due 2006, issued April 9, 1996. In addition, the CEX partnership interests have been pledged as collateral under the 12% Senior Notes. 4. RELATED PARTY TRANSACTIONS CEX has significant transactions with COI, CEC, CGDC and other affiliated companies included in the CEC consolidated group, including: COI as operator for CEX: (a) acquires oil and gas properties, (b) drills and equips wells, (c) operates the majority of CEX's wells, (d) sells interests in proved undeveloped properties to third parties, and F-37

88 CHESAPEAKE EXPLORATION LIMITED PARTNERSHIP (A WHOLLY-OWNED PARTNERSHIP OF CHESAPEAKE ENERGY CORPORATION) NOTES TO FINANCIAL STATEMENTS -- (CONTINUED) (e) contracts services from affiliated entities in the CEC consolidated group and from third parties on behalf of CEX. Capitalized costs associated with these transactions are reflected in the balance sheet as oil and gas properties and unevaluated properties for each period presented. Production expenses and taxes included in the statement of operations for each of the periods presented reflect expenses billed by COI to CEX for operations. Allocated general and administrative expenses reflect amounts allocated to CEX by COI. The Company makes periodic advances (and contributions) to CEX.

MAJOR CUSTOMERS Sales to individual customers constituting 10% or more of total oil and gas sales were as follows: PERCENT OF YEAR AMOUNTS OIL AND GAS SALES - ---- ---------------- ----------------- ($ IN THOUSANDS) 1996 Aquila Southwest Pipeline Corporation $41,900 40% GPM Gas Corporation $28,700 28% Wickford Energy Marketing, L.C. $18,500 18% 1995 Aquila Southwest Pipeline Corporation $18,548 33% Wickford Energy Marketing, L.C. $15,704 28% GPM Gas Corporation $11,686 21% 1994 Wickford Energy Marketing, L.C. $ 6,190 28% GPM Gas Corporation $ 6,105 27% Plains Marketing and Transportation, Inc. $ 2,659 12% Texaco Exploration & Production, Inc. $ 2,249 10% Management believes that the loss of any of the above customers would not have a material impact on CEX's results of operations or its financial position. 6. FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES The Company, on behalf of CEX, has only limited involvement with derivative financial instruments, as defined in Statement of Financial Accounting Standards No. 119 "Disclosure About Derivative Financial Instruments and Fair Value of Financial Instruments" and does not use them for trading purposes. The Company's objective is to hedge a portion of its exposure to price volatility from producing crude oil and natural gas. These arrangements may expose the Company to credit risk from its counter-parties and to basis risk. Hedging Activities Periodically the Company, on behalf of CEX, utilizes hedging strategies to hedge the price of a portion of its future oil and gas production. These strategies include swap arrangements that establish an index-related price above which the Company pays the hedging partner and below which the Company is paid by the hedging partner, the purchase of index-related puts that provide for a "floor" price to the Company to be paid by the counter-party to the extent the price of the commodity is below the contracted floor, and basis protection swaps. As of June 30, 1996, the Company had NYMEX-based crude oil swap agreements for 1,000 Bbl per day for July 1, 1996 through August 31, 1996 at an average price of $17.85 per Bbl. The counter-party has the option exercisable monthly for an additional 1,000 Bbl per day for the period July 1, 1996 through December 31, 1996 to cause a swap if the price exceeds an average $17.74 per Bbl. The actual settlements for July and August resulted in a $0.5 million payment to the counter-party. The Company estimates, based on NYMEX prices as of August 30, 1996 that the effect of the September through December hedges would be a $0.4 million payment to the counter-party. The Company has purchased Houston Ship Channel put options which guarantee the Company an average floor price of $2.21/Mmbtu for 20,000 Mmbtu per day for the period of November 1, 1996 through February 28, 1997. The average cost of these puts was $0.14 per Mmbtu. As of June 30, 1996, the Company had NYMEX-based natural gas swaps and NYMEX/Houston Ship Channel Basis swaps for the months of July through October 1996. These transactions resulted in payments to F-39

90 CHESAPEAKE EXPLORATION LIMITED PARTNERSHIP (A WHOLLY-OWNED PARTNERSHIP OF CHESAPEAKE ENERGY CORPORATION) NOTES TO FINANCIAL STATEMENTS -- (CONTINUED) the Company's counter-party of approximately $2 million for the month of July 1996 and $1.5 million for the month of August 1996. The Company estimates, based on NYMEX prices as of August 30, 1996, that the effect of the September and October hedges would be a $0.2 million payment to the counter-party. Concentration of Credit Risk Financial instruments which potentially subject CEX to concentrations of credit risk consist principally of trade receivables. CEX's accounts receivable are primarily from purchasers of oil and natural gas products and exploration and production companies which own interests in properties operated by the Company. The industry concentration has the potential to impact CEX's overall exposure to credit risk, either positively or negatively, in that the customers may be similarly affected by changes in economic, industry or other conditions. The Company generally requires letters of credit for receivables from customers which are not considered investment grade, unless the credit risk can otherwise be mitigated. Fair Value of Financial Instruments The following disclosure of the estimated fair value of financial instruments is made in accordance with the requirements of Statement of Financial Accounting Standards No. 107, "Disclosures About Fair Value of Financial Instruments". The estimated fair value amounts have been determined by the Company using available market information and valuation methodologies. Considerable judgment is required in interpreting market data to develop the estimates of fair value. The use of different market assumptions or valuation methodologies may have a material effect on the estimated fair value amounts. The carrying values of items comprising current assets and current liabilities approximate fair values due to the short-term maturities of these instruments. Based on the borrowing rates currently available to CEX for bank loans with similar terms and average maturities, the fair value of long-term debt approximates the carrying value. 7. DISCLOSURES ABOUT OIL AND GAS PRODUCING ACTIVITIES Net Capitalized Costs Evaluated and unevaluated capitalized costs related to CEX's oil and gas producing activities are summarized as follows: JUNE 30, -------------------- 1996 1995 -------- -------- ($ IN THOUSANDS) Oil and gas properties: Proved...................................................... $346,821 $163,521 Unproved.................................................... 165,441 27,474 -------- -------- Total..................................................... 512,262 190,995 Less accumulated depreciation, depletion and amortization...

Oil and Gas Reserve Quantities (Unaudited) The reserve information presented below is based upon reports prepared by the independent petroleum engineering firm of Williamson Petroleum Consultants, Inc. ("Williamson") as of June 30, 1996, June 30, 1995 and June 30, 1994 and the Company's petroleum engineers as of June 30, 1996 and 1995. The reserves evaluated by the Company's petroleum engineers constituted approximately 0.6% and 0.5% of total proved reserves as of June 30, 1996 and 1995, respectively. The information is presented in accordance with regulations prescribed by the Securities and Exchange Commission. CEX emphasizes that reserve estimates are inherently imprecise. CEX's reserve estimates were generally based upon extrapolation of historical production trends, analogy to similar properties and volumetric calculations. Accordingly, these estimates are expected to change, and such changes could be material, as future information becomes available. Proved oil and gas reserves represent the estimated quantities of crude oil, natural gas, and natural gas liquids which geological and engineering data demonstrate with reasonable certainty to be recoverable in F-41

Proved developed oil and gas reserves are those expected to be recovered through existing wells with existing equipment and operating methods. Presented below is a summary of changes in estimated reserves of CEX based upon the reports prepared by Williamson for 1996, 1995 and 1994 along with those prepared by the Company's petroleum engineers for 1996 and 1995.

The properties are located in the Knox and Golden Trend fields of southern Oklahoma, most of which are operated by the Company. In October 1993, CEX entered into a joint development agreement covering a 20,000 gross acre development area in the Fayette County portion of the Giddings Field in southern Texas. CEX's ownership interests in the proved undeveloped properties covered by the joint development agreement were significantly less than those used in the June 30, 1993 reserve report. The impact of the reduced ownership percentages is reflected as sales of reserves in place in fiscal 1994 in the preceding table. Standardized Measure of Discounted Future Net Cash Flows (Unaudited) Statement of Financial Accounting Standards No. 69 ("SFAS 69") prescribes guidelines for computing a standardized measure of future net cash flows and changes therein relating to estimated proved reserves. CEX has followed these guidelines which are briefly discussed below. Future cash inflows and future production and development costs are determined by applying year-end prices and costs to the estimated quantities of oil and gas to be produced. Estimates are made of quantities of proved reserves and the future periods during which they are expected to be produced based on year-end economic conditions. Estimated future income taxes are computed using current statutory income tax rates including consideration for the current tax basis of the properties and related carryforwards, giving effect to permanent differences and tax credits. The income tax effect of these future cash inflows will be recognized by CEX's partners. The resulting future net cash flows are reduced to present value amounts by applying a 10% annual discount factor. The assumptions used to compute the standardized measure are those prescribed by the Financial Accounting Standards Board and, as such, do not necessarily reflect CEX's expectations of actual revenue to F-42

The limitations inherent in the reserve quantity estimation process, as discussed previously, are equally applicable to the standardized measure computations since these estimates are the basis for the valuation process.

97 CHESAPEAKE ENERGY CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 1996 (UNAUDITED) 1. ACCOUNTING PRINCIPLES The accompanying unaudited consolidated financial statements of Chesapeake Energy Corporation and Subsidiaries (the "Company") have been prepared in accordance with the instructions to Form 10-Q as prescribed by the Securities and Exchange Commission. All material adjustments (consisting solely of normal recurring adjustments) which, in the opinion of management, are necessary for a fair presentation of the results for the interim periods have been reflected. The results for the three months and six months ended December 31, 1996, are not necessarily indicative of the results to be expected for the full fiscal year. 2. RECENT EVENTS On November 25, 1996, the Company issued 8,000,000 shares of Common Stock in a public offering at a price of $33.63 per share, which resulted in net proceeds to the Company of approximately $256.9 million. On December 2, 1996, the underwriters of the Company's Common Stock offering exercised an over-allotment option to purchase an additional 972,000 shares of Common Stock at a price of $33.63 per share, resulting in additional net proceeds to the Company of approximately $31.2 million, and total proceeds of $288.1 million. Using a portion of the proceeds from the Common Stock offering, the Company exercised its covenant defeasance rights under Section 8.03 of the Indenture dated as of March 31, 1994 with respect to all of its outstanding $47.5 million of 12% Senior Notes. A combination of cash and non-callable U.S. Government Securities in the amount of $55 million was irrevocably deposited in trust to satisfy the Company's obligations, including accrued but unpaid interest through the date of defeasance of $1.3 million. The Company also repaid in full the outstanding balance of its revolving bank credit facility. Effective December 31, 1996, the Company changed its state of incorporation from Delaware to Oklahoma. As part of this transaction, the authorized capital stock of the Company was increased to 100,000,000 shares of common stock, par value $.01 per share, and 10,000,000 shares of preferred stock, par value $.01 per share. Also effective December 31, 1996, the Company effected a 2-for-1 split of its common stock. All par value, share and per share information, common stock options and exercise prices included in these consolidated financial statements and related footnotes have been restated to reflect the stock split. 3. LEGAL PROCEEDINGS On October 15, 1996, Union Pacific Resources Company ("UPRC") filed suit against the Company alleging patent infringement and tortious interference with contracts regarding confidentiality and proprietary information of UPRC. UPRC is seeking injunctive relief and damages in an unspecified amount, including actual, enhanced, consequential and punitive damages. The Company believes it has meritorious defenses to the allegations, including its belief that the subject patent is invalid. Given the subject of the claims, the Company is unable to predict the outcome of the matter or estimate a range of financial exposure. 4. SENIOR NOTES 10 1/2% Notes The Company has outstanding $90 million in aggregate principal amount of 10 1/2% Notes which mature June 2002. The 10 1/2% Notes bear interest at an annual rate of 10 1/2%, payable semiannually on each June 1 and December 1. The 10 1/2% Notes are senior, unsecured obligations of the Company, and are fully and unconditionally guaranteed, jointly and severally, by certain subsidiaries of the Company (the "Guarantor Subsidiaries"). F-47

98 CHESAPEAKE ENERGY CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) (UNAUDITED) 9 1/8% Notes The Company has outstanding $120 million in aggregate principal amount of 9 1/8% Senior Notes due 2006 which mature April 15, 2006. The 9 1/8% Notes bear interest at an annual rate of 9 1/8%, payable semiannually on each April 15 and October 15. The 9 1/8% Notes are senior, unsecured obligations of the Company, and are fully and unconditionally guaranteed, jointly and severally, by the Guarantor Subsidiaries. Set forth below are condensed consolidating financial statements of the Guarantor Subsidiaries, the Non-Guarantor Subsidiaries and the Company. Separate financial statements of each Guarantor Subsidiary have not been included because management has determined that they are not material to investors. F-48

106 PART II INFORMATION NOT REQUIRED IN PROSPECTUS ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS As permitted by the Oklahoma General Corporation Act under which the Company is incorporated, the Company's Certificate of Incorporation provides for indemnification of each of the Company's officers and directors against (a) expenses, including attorneys' fees, judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with any action, suit or proceeding brought by reason of his being or having been a director, officer, employee or agent of the Company, or of any other corporation, partnership, joint venture, or other enterprise at the request of the Company, other than an action by or in the right of the Company, provided that he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interest of the Company, and with respect to any criminal action, he had no reasonable cause to believe that his conduct was unlawful and (b) expenses, including attorneys' fees, actually and reasonably incurred by him in connection with the defense or settlement of any action or suit by or in the right of the Company brought by reason of his being or having been a director, officer, employee or agent of the Company, or any other corporation, partnership, joint venture, or other enterprise at the request of the Company, provided that he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interest of the Company, except that no indemnification shall be made in respect of any claim, issue or matter as to which he shall have been adjudged liable to the Company, 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. The Company's bylaws provide for similar indemnification. These provisions may be sufficiently broad to indemnify such persons for liabilities arising under the Securities Act of 1933, as amended. The Company has entered into indemnity agreements with each of its directors and executive officers. Under each indemnity agreement, the Company will pay on behalf of the indemnitee, and his executors, administrators and heirs, any amount which he is or becomes legally obligated to pay because of (i) 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 the Company or an affiliate or (ii) 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 the Company or an affiliate or is or was serving at the request of the Company as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise. The payments which the Company will be obligated to make thereunder shall include, inter alia, 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. The Company also provides liability insurance for each of its directors and executive officers. ITEM 21. EXHIBITS AND FINANCIAL STATEMENT SCHEDULES.

108 ITEM 22. UNDERTAKINGS. The undersigned Registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement: (i) To include any prospectus required by section 10(a)(3) of the Securities Act of 1933; (ii) To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement; (iii) To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement. Provided, however, that paragraphs (1)(i) and (1)(ii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the Registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the Registration Statement. (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at the 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. The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant's 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. The undersigned Registrant hereby undertakes 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. The undersigned Registrant hereby undertakes 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 the Registration Statement when it became effective. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registration pursuant to the provisions described under Item 20, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the 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, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

The Company shall approve the form of the Securities and any notation, legend or endorsement on them. Each Security shall be dated the date of its authentication. The terms and provisions contained in the Securities and the Guarantee shall constitute, and are hereby expressly made, a part of this Indenture and, to the extent applicable, the Company and the Subsidiary Guarantors, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. 13

21 Securities offered and sold in their initial distribution in reliance on Regulation S may be initially issued in the form of temporary Global Securities in fully registered form without interest coupons, substantially in the form of Exhibit A, with such applicable legends as are provided for in Exhibit A hereto. Such temporary Global Securities may be registered in the name of the Depository or its nominee and deposited with the Trustee, as custodian for the Depository, duly executed by the Company and authenticated by the Trustee as hereinafter provided, for credit by the Depository to the respective accounts of the beneficial owners of the Securities represented thereby (or such other accounts as they may direct), provided that upon such deposit all such Securities shall be credited to or through accounts maintained at the Depository by or on behalf of Euroclear or CEDEL. Until such time as the Restricted Period (as defined below) shall have expired, any such temporary Global Securities, together with their Successor Securities which are Global Securities other than the Restricted Global Security, shall each be referred to herein as a "Temporary Regulation S Global Security." After such time as the Restricted Period shall have expired and the certifications referred to in the next succeeding paragraph shall have been provided, interests in such Temporary Regulation S Global Securities shall be exchanged for interests in like Global Securities, each referred to herein collectively as a "Permanent Regulation S Global Security," substantially in the form of Security set forth in Exhibit A, with such applicable legends as are provided for in Exhibit A. Such Permanent Regulation S Global Securities shall be registered in the name of the Depository or its nominee and deposited with the Trustee, as custodian for the Depository, duly executed by the Company and authenticated by the Trustee as hereinafter provided, for credit to the respective accounts of the beneficial owners of the Securities represented thereby (or such other accounts as they may direct). The aggregate principal amount of the Temporary Regulation S Global Security or the Permanent Regulation S Global Security may be increased or decreased from time to time by adjustments made on the records of the Trustee, as custodian for the Depository, as hereinafter provided. As used herein, the term "Restricted Period" means the period of 40 days commencing on the day after the latest of (a) the day on which the Securities are first offered to persons other than distributors (as defined in Regulation S) in reliance on Regulation S and (b) the Issue Date. Interests in a Temporary Regulation S Global Security may be exchanged for interests in a Permanent Regulation S Global Security only after (a) the expiration of the Restricted Period, (b) delivery by a beneficial owner of an interest therein to Euroclear or CEDEL of a written certification (an "Owner Securities Certification") substantially in the form of Exhibit C hereto, and (c) upon delivery by Euroclear or CEDEL to the Trustee of a written certification (a "Depository Securities Certification") substantially in the form attached hereto as Exhibit D. Upon satisfaction of such conditions, the Trustee will exchange the portion of the Temporary Regulation S Global Security covered by such certification for interests in a Permanent Regulation S Global Security. The delivery by such Holder of a beneficial interest in such Temporary Regulation S Global Security of such certification shall constitute an irrevocable instruction by such holder to Euroclear or CEDEL, as the case may be, to exchange such Holder's beneficial interest in the Temporary Regulation S Global Security for a beneficial interest in the Permanent Regulation S Global Security upon the expiration of the Restricted Period in accordance with the next succeeding paragraph. Upon: 14

22 (i) the expiration of the Restricted Period; (ii) receipt by Euroclear or CEDEL, as the case may be, of Owner Securities Certifications described in the preceding paragraph; (iii) receipt by the Depository of: (1) written instructions given in accordance with the Applicable Procedures from an Agent Member directing the Depository to credit or cause to be credited to a specified Agent Member's account a beneficial interest in a Permanent Regulation S Global Security in a principal amount equal to that of the beneficial interest in a corresponding Temporary Regulation S Global Security for which the necessary certifications have been delivered; and (2) a written order given in accordance with the Applicable Procedures containing information regarding the account of the Agent Member, and the Euroclear or CEDEL account for which such Agent Member's account is held, to be credited with, and the account of the Agent Member to be debited for, such beneficial interest; and (iv) receipt by the Trustee of notification from the Depository of the transactions described in (iii) above and from Euroclear or CEDEL, as the case may be, of Depository Securities Certifications, the Trustee, as Registrar (as defined below), shall instruct the Depository to reduce the principal amount of such Temporary Regulation S Global Security and to increase the principal amount of such Permanent Regulation S Global Security, by the principal amount of the beneficial interest in such Temporary Regulation S Global Security to be so transferred, and to credit or cause to be credited to the account of the person specified in such instructions a beneficial interest in such Permanent Regulation S Global Security having a principal amount equal to the amount by which the principal amount of such Temporary Regulation S Global Security was reduced upon such transfer. Securities offered and sold in their initial distribution in reliance on Rule 144A under the Securities Act and other than in reliance on Rule 144A under the Securities Act or Regulation S shall be issued in the form of one or more Global Securities (collectively, and, together with their Successor Securities, the "Restricted Global Security") in fully registered form without interest coupons, substantially in the form of Security set forth in Exhibit A hereto, with such applicable legends as are provided for in Exhibit A except as otherwise permitted herein. Such Restricted Global Security shall be registered in the name of the Depository or its nominee and deposited with the Trustee, as custodian for the Depository, duly executed by the Company and authenticated by the Trustee as hereinafter provided, for credit by the Depository to the respective accounts of beneficial owners of the securities represented thereby (or such other accounts as they may direct). 15

23 The aggregate principal amount of the Restricted Global Security may be increased or decreased from time to time by adjustments made on the records of the Trustee, as custodian for the Depository, in connection with a corresponding decrease or increase in the aggregate principal amount of the Temporary Regulation S Global Security or the Permanent Regulation S Global Security, as hereinafter provided. SECTION 2.2 Execution and Authentication. Two Officers of the Company shall sign the Securities on behalf of the Company, and one Officer of each Subsidiary Guarantor shall sign the notation on the Securities relating to the Guarantee of such Subsidiary Guarantor on behalf of such Subsidiary Guarantor, in each case by manual or facsimile signature. The Company's seal shall be reproduced on the Securities. If an Officer of the Company or any Subsidiary Guarantor whose signature is on a Security no longer holds that office at the time the Security is authenticated, the Security shall be valid nevertheless. A Security shall not be valid until the Trustee or an authenticating agent manually signs the certificate of authentication on the Security. The signature shall be conclusive evidence that the Security has been authenticated under this Indenture. The Trustee or an authenticating agent shall authenticate Securities for original issue in the aggregate principal amount of $150,000,000 upon a written order of the Company signed by two Officers of the Company. The aggregate principal amount of Securities outstanding at any time may not exceed $150,000,000. Series B Notes may be issued only in exchange for a like principal amount of Series A Notes pursuant to an Exchange Offer. The principal and interest on Book-Entry Securities shall be payable to the Depository or its nominee, as the case may be, as the sole registered owner and the sole holder of the Book-Entry Securities represented thereby. The principal and interest on Securities in certificated form shall be payable at the office of the Paying Agent. The Trustee may appoint an authenticating agent to authenticate Securities. An authenticating agent may authenticate Securities whenever the Trustee may do so except on original issuance. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with the Company or its Affiliates. The Securities shall be issuable only in registered form without coupons and only in denominations of $1,000 and any integral multiple thereof. 16

24 If the Securities are to be issued in the form of one or more Global Securities, then the Company shall execute and the Trustee shall authenticate and deliver one or more Global Securities that shall represent and shall be in minimum denominations of $1,000. SECTION 2.3 Registrar and Paying Agent. The Company shall maintain an office or agency where the 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. Where the Trustee is acting as or has been appointed Registrar and/or Paying Agent, the Company may appoint one or more co- registrars and one or more additional paying agents with the prior consent of the Trustee, whose consent shall not be unreasonably withheld. The term "Paying Agent" includes any additional paying agent. The Company shall enter into an appropriate agency agreement with any Agent not a party to this Indenture. Such agency agreement shall provide for reasonable compensation for such services. 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 or act as Registrar or Paying Agent, the Trustee shall act as such and shall be duly compensated therefor. The Registrar or a co-registrar and a Paying Agent shall be maintained by the Company in the Borough of Manhattan, the City of New York. The Company initially designates the Trustee as the Registrar and Paying Agent. The Company initially appoints the Trustee to act as the Registrar and Paying Agent and to act as Securities Custodian with respect to the Global Securities. SECTION 2.4 Paying Agent to Hold Money in Trust. The Company shall require each Paying Agent other than the Trustee to hold in trust for the benefit of Holders or the Trustee all money held by such Paying Agent for the payment of principal of, premium, if any, or interest on the Securities (whether such money shall have been paid to it by the Company or any Subsidiary Guarantor), and to notify the Trustee of any Default by the Company or any Subsidiary Guarantor in making any such payment. While any such Default continues, the Trustee may require the Paying Agent to pay all money held by it to the Trustee. Except as provided in the immediately preceding sentence, 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 and, if the Company requires such payment, the Company shall give prior notice to the Trustee and provide appropriate money transfer instructions to the Paying Agent. Upon such payment over to the Trustee and accounting for any funds disbursed, such Paying Agent (if other than the Company or a Subsidiary) shall have no further liability for the money. If the Company or a Subsidiary acts as Paying Agent, 17

25 it shall segregate and hold as separate trust funds for the benefit of the Holders all money held by it as Paying Agent. SECTION 2.5 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 and shall otherwise comply with TIA Section 312(a). If the Trustee is not the Registrar, the Company shall furnish or cause to be furnished to the Trustee at least ten Business Days prior to each semiannual 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, and the Company shall otherwise comply with TIA Section 312(a). SECTION 2.6 Transfer and Exchange. (a) Beneficial interests in a Global Security may, subject to the restrictions on the transferability of the Securities and upon delivery of a certificate in the form of Exhibit B hereto be exchanged for certificated Securities upon request but only upon at least 20 days' prior written notice given to the Trustee by or on behalf of the Depository (in accordance with the Depository's customary procedures) and will bear the applicable legends set forth in Exhibit A hereto. (b) If any Global Security is to be exchanged for other Securities or canceled in whole, it shall be surrendered by or on behalf of the Depository or its nominee to the Trustee, as Registrar, for exchange or cancellation as provided in this Article II. If any Global Security is to be exchanged for other Securities or cancelled in part, or if another Security is to be exchanged in whole or in part for a beneficial interest in any Global Security, such Global Security shall be so surrendered for exchange or cancellation as provided in this Article II or, if the Trustee is acting as custodian for the Depository or its nominee (or is party to a similar arrangement) with respect to such Global Security, the principal amount thereof shall be reduced or increased by an amount equal to the portion thereof to be so exchanged or cancelled, or the principal amount of such other Security to be so exchanged for a beneficial interest therein, as the case may be, in each case by means of an appropriate adjustment made on the records of the Trustee, whereupon the Trustee, in accordance with the Applicable Procedures, shall instruct the Depository or its authorized representatives to make a corresponding adjustment to its records (including by crediting or debiting any Agent Member's account as necessary to reflect any transfer or exchange of a beneficial interest). Upon any such surrender or adjustment of a Global Security, the Trustee shall, subject to this Article II, authenticate and deliver any Securities issuable in exchange for such Global Security (or any portion thereof) to or upon the order of, and registered in such names as may be directed by, the Depository or its authorized representative. Upon the request of the Trustee in connection with the occurrence of any of the events specified in the preceding paragraph or in clause (r) below, the Company shall promptly make available to the Trustee a reasonable supply of Securities that are not in the form of Global Securities. The Trustee shall be entitled to rely upon any order, direction or request of the 18

26 Depository or its authorized representative which is given or made pursuant to this Article II if such order, direction or request is given or made in accordance with the Applicable Procedures. (c) Subject to the provisions in the legends required by this Indenture, the registered Holder may grant proxies and otherwise authorize any Person, including Agent Members and Persons who may hold interests in Agent Members to take any action that such Holder is entitled to take under this Indenture. (d) Neither Agent Members nor any other Person on whose behalf Agent Members may act shall have any rights under this Indenture with respect to any Global Security held on their behalf by the Depository or under the Global Security, and the Depository may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depository or impair, as between the Depository and its Agent Members, the operation of customary practice governing the exercise of the rights of a Holder of any Security. With respect to any Global Security deposited with the Trustee as custodian for the Depository for credit to their respective accounts (or to such other accounts as they may direct) at Euroclear or CEDEL, the provisions of the "Operating Procedures of the Euroclear System" and the "Terms and Conditions Governing Use of Euroclear," and the "Management Regulations" and "Instructions to Participants" of CEDEL, respectively, shall be applicable to such Global Security. (e) Upon presentation for transfer and exchange of any Security at the office of the Trustee, as Registrar, located in The City of New York, accompanied by a written instrument of transfer or exchange in the form approved by the Company (it being understood that, until notice to the contrary is given to holders of Securities, the Company shall be deemed to have approved the form of instrument of transfer or exchange, if any, printed on any Security), executed by the registered Holder, in person or by such Holder's attorney thereunto duly authorized in writing, and upon compliance with this Section 2.6, such Security shall be transferred upon the Register, and a new Security shall be authenticated and issued in the name of the transferee. Notwithstanding any provision to the contrary herein or in the Securities, transfers of a Global Security, in whole or in part, and transfers of interests therein of the kind described in this Section 2.6, shall only be made in accordance with this Section 2.6. Transfers and exchanges subject to this Section 2.6 shall also be subject to the other provisions of this Indenture that are not inconsistent with this Section 2.6. (f) General. A Global Security may not be transferred, in whole or in part, to any Person other than the Depository or a nominee thereof, and no such transfer to any such other Person may be registered; provided, however, that this clause (f) shall not prohibit any transfer of a Security that is issued in exchange for a Global Security but is not itself a Global Security. No transfer of a Security to any Person shall be effective under this Indenture or the Securities unless and until such Security has been registered in the name of such Person. Nothing in this clause (f) shall prohibit or 19

27 render ineffective any transfer of a beneficial interest in a Global Security effected in accordance with the other provisions of this Section 2.6. (g) Temporary Regulation S Global Security. If the holder of a beneficial interest in a Temporary Regulation S Global Security wishes at any time to transfer such interest to a Person who wishes to take delivery thereof in the form of a beneficial interest in such Temporary Regulation S Global Security, such transfer may be effected, subject to the rules and procedures of the Depository, Euroclear and CEDEL, in each case to the extent applicable and as in effect from time to time (the "Applicable Procedures"), only in accordance with this clause (g). Upon delivery (i) by a beneficial owner of an interest in a Temporary Regulation S Global Security to Euroclear or CEDEL, as the case may be, of an Owner Securities Certification, (ii) by the transferee of such beneficial interest in the Temporary Regulation S Global Security to Euroclear or CEDEL, as the case may be, of a written certification (a "Transferee Securities Certification") substantially in the form of Exhibit E hereto and (iii) by Euroclear or CEDEL, as the case may be, to the Trustee, as Registrar, of a Depository Securities Certification, the Trustee may direct either Euroclear or CEDEL, as the case may be, to reflect on its records the transfer of a beneficial interest in the Temporary Regulation S Global Security from the beneficial owner providing the Owner Securities Certification to the Person providing the Transferee Securities Certification. (h) Restricted Global Security to Temporary Regulation S Global Security. If the holder of a beneficial interest in the Restricted Global Security wishes at any time to transfer such interest to a Person who wishes to take delivery thereof in the form of a beneficial interest in the Temporary Regulation S Global Security, such transfer may be effected, subject to the Applicable Procedures, only in accordance with the provisions of this clause (h) and clause (n) below. Upon receipt by the Trustee, as Registrar, of (A) written instructions given by or on behalf of the Depository in accordance with the Applicable Procedures directing the Trustee to credit or cause to be credited to a specified Agent Member's account a beneficial interest in the Temporary Regulation S Global Security in a specified principal amount and to cause to be debited from another specified Agent Member's account a beneficial interest in the Restricted Global Security in an equal principal amount and (B) a certificate in substantially the form set forth in Exhibit F hereto signed by or on behalf of the holder of such beneficial interest in the Restricted Global Security, the Trustee, as Registrar, shall, subject to clause (n) below, reduce the principal amount of the Restricted Global Security, and increase the principal amount of the Temporary Regulation S Global Security by such specified principal amount. (i) Restricted Global Security to Permanent Regulation S Global Security. If the holder of a beneficial interest in the Restricted Global Security wishes at any time to transfer such interest to a Person who wishes to take delivery thereof in the form of a beneficial interest in the Permanent Regulation S Global Security, such transfer may be effected, subject to the Applicable Procedures, only in accordance with this clause (i). Upon receipt by the Trustee, as Registrar, of (A) written instructions given by or on behalf of the Depository in accordance with the Applicable Procedures directing the Trustee to credit or cause to be credited to a specified Agent Member's account a beneficial interest in the Permanent Regulation S Global Security in a specified principal 20

28 amount and to cause to be debited from another specified Agent Member's account a beneficial interest in the Restricted Global Security in an equal principal amount and (B) a certificate in substantially the form set forth in Exhibit G hereto signed by or on behalf of the holder of such beneficial interest in the Restricted Global Security, the Trustee, as Registrar, shall reduce the principal amount of a Restricted Global Security, and increase the principal amount of the Permanent Regulation S Global Security by such specified principal amount. (j) Temporary Regulation S Global Security or Permanent Regulation S Global Security to Restricted Global Security. If the holder of a beneficial interest in the Temporary Regulation S Global Security or the Permanent Regulation S Global Security at any time, wishes to transfer such interest to a Person who wishes to take delivery thereof in the form of a beneficial interest in the Restricted Global Security, such transfer may be effected, subject to the Applicable Procedures, only in accordance with this clause (j) and clause (n) below; provided, that with respect to any transfer of a beneficial interest in a Temporary Regulation S Global Security, the transferor and Euroclear or CEDEL, as the case may be, must have previously delivered an Owner Securities Certification and a Depository Securities Certification respectively, with respect to such beneficial interest. Upon receipt by the Trustee, as Registrar, of (A) written instructions given by or on behalf of the Depository in accordance with the Applicable Procedures directing the Trustee to credit or cause to be credited, to a specified Agent Member's account a beneficial interest in the Restricted Global Security in a specified principal amount and to cause to be debited from another specified Agent Member's account a beneficial interest in the Temporary Regulation S Global Security or the Permanent Regulation S Global Security, as the case may be, in an equal principal amount and (B) a certificate in substantially the form set forth in Exhibit H signed by or on behalf of the holder of such beneficial interest in the Temporary Regulation S Global Security or the Permanent Regulation S Global Security, as the case may be, the Trustee, as Security Registrar, shall, subject to clause (n) below, reduce the principal amount of such Temporary Regulation S Global Security or Permanent Regulation S Global Security, as the case may be, and increase the principal amount of the Restricted Global Security by such specified principal amount. (k) Non-Global Restricted Security to Restricted Global Security. If the holder of a Restricted Security (other than a Global Security) wishes at any time to transfer all or any portion of such Security to a Person who wishes to take delivery thereof in the form of a beneficial interest in the Restricted Global Security, the Temporary Regulation S Global Security or the Permanent Regulation S Global Security, such transfer may be effected, subject to the Applicable Procedures, only in accordance with this clause (k) and clause (n) below. Upon receipt by the Trustee, as Registrar, of (A) such Security and written instructions given by or on behalf of such Holder as provided in this Section 2.6 directing the Trustee to credit or cause to be credited to a specified Agent Member's account a beneficial interest in the Restricted Global Security, the Temporary Regulation S Global Security or the Permanent Regulation S Global Security, as the case may be, in a specified principal amount equal to the principal amount of the Restricted Security (or portion thereof) to be so transferred, and (B) an appropriately completed certificate substantially in the form set forth in Exhibit I-1 hereto, if the specified account is to be credited with a beneficial interest in the Restricted Global Security, or Exhibit I-2 herein, if the specified account is to be 21

29 credited with a beneficial interest in the Temporary Regulation S Global Security or the Permanent Regulation S Global Security, signed by or on behalf of such Holder, then the Trustee, as Registrar, shall, subject to clause (n) below, cancel such Restricted Security (and issue a new Security in respect of any untransferred portion thereof) as provided in this Section 2.6 and increase the principal amount of the Restricted Global Security, Temporary Regulation S Global Security or Permanent Regulation S Global Security, as the case may be, by the specified principal amount. (l) Non-Global Permanent Regulation S Security to Restricted Global Security or Permanent Regulation S Global Security. If the Holder of a Permanent Regulation S Security (other than a Global Security) wishes at any time to transfer all or any portion of such Security to a Person who wishes to take delivery thereof in the form of a beneficial interest in the Restricted Global Security or the Permanent Regulation S Global Security, as the case may be, such transfer may be effected only in accordance with this clause (1) and subject to the Applicable Procedures. Upon receipt by the Trustee, as Registrar, of (A) such Security and instructions given by or on behalf of such Holder as provided in this Section 2.6 directing the Trustee to credit or cause to be credited to a specified Agent Member's account a beneficial interest in the Restricted Global Security or the Permanent Regulation S Global Security, as the case may be, in a principal amount equal to the principal amount of the Security (or portion thereof) to be so transferred, and (B) (i) with respect to a transfer which is to be delivered in the form of a beneficial interest in the Restricted Global Security, a certificate in substantially the form set forth in Exhibit J-1 hereto, signed by or on behalf of such Holder, and (ii) with respect to a transfer which is to be delivered in the form of a beneficial interest in the Permanent Regulation S Global Security, a certificate in substantially the form set forth in Exhibit J-2 hereto, signed by or on behalf of such Holder, then the Trustee, as Registrar, shall, subject to clause (q) below, cancel such Security (and issue a new Security in respect of any untransferred portion thereof) as provided in this Section 2.6 and increase the principal amount of the Restricted Global Security, or the Permanent Regulation S Global Security, as the case may be, by the specified principal. (m) Other Exchanges. Securities that are not Global Securities may be exchanged (on transfer or otherwise) for Securities that are not Global Securities or for beneficial interests in a Global Security (if any is then outstanding) only in accordance with such procedures, which shall be substantially consistent with the provisions of clauses (f) through (l) above (including the certification requirements intended to insure that transfers of beneficial interests in a Global Security comply with Rule 144A under the Securities Act or Regulation S, as the case may be) and any Applicable Procedures, as may from time to time be adopted by the Company and the Trustee. (n) Interests in Temporary Regulation S Global Security to be Held Through Euroclear or CEDEL. Until the later of the expiration of the Restricted Period and the provision of the Owner Securities Certification and the Depository Securities Certification, beneficial interests in any Temporary Regulation S Global Security may be held only in or through accounts maintained at the Depository by Euroclear or CEDEL (or by Agent Members acting for the account thereof). 22

30 (o) When Securities in certificated form are presented to the Registrar with a request to register the transfer of such Securities or to exchange such Securities for an equal principal amount of Securities of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested if its requirements for such transaction are met; provided, however, that the Securities surrendered for transfer or exchange shall be duly endorsed or accompanied by a written instrument of transfer in form satisfactory to the Company and the Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing. To permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Securities at the Registrar's request. No service charge shall be made for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchanges or transfers pursuant to Sections 2.2, 2.10, 3.7 or 9.5). The Registrar shall not be required to register the transfer of or exchange of any Security (i) during a period beginning at the opening of business 15 days before the mailing of a notice of redemption of Securities and ending at the close of business on the day of such mailing and (ii) selected for redemption in whole or in part pursuant to Article Three, except the unredeemed portion of any Security being redeemed in part. (p) If a Series A Note is a Restricted Security in certificated form, then as provided in this Indenture and subject to the limitations herein set forth, the Holder, provided it is a Qualified Institutional Buyer or an institutional "accredited investor" (as defined in Rule 501(a)(1), (2), (3) or (7) under the Securities Act), may exchange such Security for a Book-Entry Security by instructing the Trustee (by completing the Transferee Certificate in the form of Exhibit B hereto) to arrange for such Series A Note to be represented by a beneficial interest in a Global Security in accordance with the customary procedures of the Depository. (q) Upon any exchange provided for in Section 2.6(a), the Company shall execute and the Trustee shall authenticate, and deliver to the person specified by the Depository a new Series A Note or Notes registered in such names and in such authorized denominations as the Depository, pursuant to the instructions of the beneficial owner of the Securities requesting the exchange, shall instruct the Trustee. Thereupon, the beneficial ownership of such Global Security shown on the records maintained by the Depository or its nominee shall be reduced by the amounts so exchanged and an appropriate endorsement be made by and on behalf of the Trustee on the Global Security. Any such exchange shall be effected through the Depository in accordance with the procedures of the Depository therefor. (r) Notwithstanding the foregoing, no Global Security shall be registered for transfer or exchange, or authenticated and delivered, whether pursuant to this Section, Section 2.7, 2.10 or 3.7 or otherwise , in the name of a person other than the Depository for such Global Security or its nominee until (i) the Depository notifies the Company that it is unwilling or unable to continue as Depository for such Global Security or if at any time the Depository ceases to be a clearing agency registered under the Exchange Act, and a successor depository is not appointed by the Company within 30 days, (ii) the Company executes and delivers to the Trustee a Company order 23

31 that all such Global Securities shall be exchangeable or (iii) there shall have occurred and be continuing an Event of Default. Upon the occurrence in respect of any Global Security representing the Series A Notes of any one or more of the conditions specified in clause (i), (ii) or (iii) of the preceding sentence, such Global Security may be registered for transfer or exchange for Series A Notes registered in the names of, authenticated and delivered to, such persons as the Trustee or the Depository, as the case may be, shall direct. (s) Except as provided above, any Security authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, any Global Security, whether pursuant to this Section 2.7, 2.10 or 3.7 or otherwise, shall also be a Global Security and bear the legend specified in footnote 1 to Exhibit A. SECTION 2.7 Replacement Securities. If a mutilated Security is surrendered to the Trustee 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 the Trustee are met. An indemnity bond may be required by the Trustee, the Company or any Subsidiary Guarantor that is sufficient in the judgment of the Company, the Subsidiary Guarantors and the Trustee to protect the Company, the Subsidiary Guarantors, the Trustee or any Agent from any loss which any of them may suffer if a Security is replaced. The Company may charge for its expenses (including fees and expenses of the Trustee) in replacing a Security. SECTION 2.8 Outstanding Securities. Senior Notes outstanding at any time are all Securities authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Security effected by the Trustee in accordance with the provisions hereof, and those described in this Section 2.8 as not outstanding. Except as set forth in Section 2.9, a Security does not cease to be outstanding because the Company, the Subsidiary Guarantors or any of their respective Subsidiaries or Affiliates holds the Security. If a Security is replaced pursuant to Section 2.7, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Security is held by a bona fide purchaser. If the principal amount of any Security is considered paid under Section 4.1, it ceases to be outstanding and interest on it ceases to accrue. SECTION 2.9 Treasury Securities. In determining whether the Holders of the required principal amount of Securities have concurred in any direction, waiver or consent, Securities owned by the Company, any Subsidiary Guarantor or an Affiliate of the Company shall be considered as though they are not outstanding, 24

32 except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Securities which the Trustee knows are so owned shall be so disregarded. SECTION 2.10 Temporary Securities. Until definitive Securities are ready for delivery, the Company may prepare and, upon written order of the Company, 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 and deliver definitive Securities in exchange for a like principal amount of temporary Securities surrendered to it. Until so exchanged, temporary Securities shall in all respects be entitled to the same benefits under this Indenture as definitive Securities. SECTION 2.11 Cancellation. The Company or any Subsidiary Guarantor at any time may deliver Securities to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any Securities surrendered to them for transfer, exchange or payment. The Trustee shall cancel all Securities surrendered for registration, transfer, exchange, payment or cancellation and shall destroy canceled Securities unless the Company directs their return to the Company. Except as provided in Section 2.7, the Company may not issue new Securities to replace Securities that it has paid or delivered to the Trustee for cancellation. Securities that are redeemed by the Company or that are otherwise acquired by the Company, will be surrendered to the Trustee for cancellation. SECTION 2.12 Defaulted Interest. If the Company defaults in a payment of interest on the Securities, it shall pay, or cause the Paying Agent to pay, the defaulted interest in any lawful manner (plus interest on such defaulted interest to the extent lawful) (taken together, the "Defaulted Interest") to the persons who are Holders on a subsequent special record date, in each case at the rate provided in the Securities and in Section 4.1 hereof. At least 15 days before the special record date, the Company shall mail to each Holder a notice stating the special record date, the payment date and the amount of Defaulted Interest to be paid. In the event that the Company has elected to cause a Paying Agent to pay the Defaulted Interest, the Company shall so notify the Paying Agent at least 15 days before the special record date, which notice shall also set forth the special record date, the payment date and the aggregate amount of Defaulted Interest to be paid.

If the Company elects to redeem Securities pursuant to the optional redemption provisions of Paragraphs 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 3.2 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.

(b) At the Company's request, the Trustee shall give the notice of redemption required in Section 3.3(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 3.3(a). SECTION 3.4 Effect of Notice of Redemption. Once notice of redemption is mailed in accordance with Section 3.3, Securities called for redemption become due and payable on the redemption date at the redemption price.

35 SECTION 3.5 Deposit of Redemption Price. Prior to the redemption date, the Company shall deposit with the Paying Agent 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 3.6 Securities Redeemed in Part. Upon surrender of a Security that is to be redeemed in part, the Company shall issue and the Trustee shall authenticate for the Holder, at the expense of the Company, a new Security equal in aggregate amount to the unredeemed portion of the Security surrendered. SECTION 3.7 Optional Redemption at Make-Whole Price. At any time, the Company may, at its option, redeem all or any portion of the Securities at the "Make-Whole Price" (hereinafter defined) plus accrued and unpaid interest to the date of redemption.

SECTION 4.6 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.

39 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 4.9 Limitation on Liens. The Company shall not, and shall not permit any Restricted Subsidiary to, issue, assume or guarantee any Indebtedness for borrowed money secured by any Lien on any property or asset now owned or hereafter acquired by the Company or such Restricted Subsidiary without making effective provision whereby any and all Securities then or thereafter outstanding will be secured by a Lien equally and ratably with any and all other obligations thereby secured for so long as any such obligations shall be so secured.

43 (3) default by the Company or any Subsidiary Guarantor in the deposit of any optional redemption payment, when and as due and payable pursuant to Article Three; (4) default on any other Indebtedness of the Company, any Subsidiary Guarantor or any other Restricted Subsidiary if either (A) such default results in the acceleration of the maturity of any such Indebtedness having a principal amount of $10.0 million or more individually or, taken together with the principal amount of any other such Indebtedness the maturity of which has been so accelerated, in the aggregate, or (B) such default results from the failure to pay when due principal of, premium, if any, or interest on, any such Indebtedness, after giving effect to any applicable grace period (a "Payment Default"), having a principal amount of $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 Article V, or in the performance, or breach of, any other covenant or agreement of the Company or any Subsidiary Guarantor in this Indenture and failure to remedy such default within a period of 45 days after written notice thereof from the Trustee or Holders of 25% of the principal amount of the outstanding Securities; (6) the entry by a court of one or more judgments or orders for the payment of money against the Company, any Subsidiary Guarantor or any other Restricted Subsidiary 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) a Guarantee by a Subsidiary Guarantor shall cease to be in full force and effect (other than a release of a Guarantee in accordance with Section 10.4) or any Subsidiary Guarantor shall deny or disaffirm its obligations with respect thereto; (8) the Company or any Restricted Subsidiary pursuant to or within the meaning of any Bankruptcy Law: (A) commences a voluntary case or proceeding, (B) consents to the entry of an order for relief against it in an involuntary case or proceeding, (C) consents to the appointment of a Custodian of it or for all or substantially all of its property, 36

The term "Bankruptcy Law" means Title 11, U.S. Code or any similar federal or state law for the relief of debtors. The term "Custodian" means any receiver, trustee, assignee, liquidator or similar official under any Bankruptcy Law. SECTION 6.2 Acceleration. If an Event of Default (other than an Event of Default specified in clauses 8 or 9) under Section 6.1 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 37

45 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 6.3 Other Remedies. If an Event of Default occurs and is continuing, the Trustee may, but is not obligated to, pursue, in its own name and as trustee of an express trust, any available remedy by proceeding at law or in equity to collect the payment of principal or interest on the Securities or to enforce the performance of any provision of the Securities or this Indenture. If an Event of Default specified under clauses (8) or (9) of Section 6.1 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 6.4 Waiver of Past Defaults. Subject to Sections 6.7 and 9.2, 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 6.5 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. 38

46 SECTION 6.6 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 (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 6.7 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 6.8 Collection Suit by Trustee. If an Event of Default in payment of principal, premium, if any, or interest specified in Section 6.1(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 39

47 of collection, including the reasonable compensation and expenses of the Trustee, its agents and counsel. SECTION 6.9 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 7.7; Second: to Holders for amounts due and unpaid on the Securities for principal and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Securities for principal and interest, respectively; and Third: To the Company. The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 6.10. SECTION 6.11 Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys' fees, 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 6.7, or a suit by Holders of more than 10% in principal amount of the then outstanding Securities. 40

48 ARTICLE VII TRUSTEE SECTION 7.1 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. Except during the continuance of an Event of Default: (i) The Trustee need perform only those duties that are specifically set forth (or incorporated by reference) in this Indenture and no others. (ii) In the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, the Trustee shall examine such certificates and opinions to determine whether or not they conform to the requirements of this Indenture. (iii) The Trustee may not be relieved from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that: (iv) This paragraph (c) does not limit the effect of paragraph (b) of this Section. (v) The Trustee shall not be liable for any error of judgment made in good faith by an officer of the Trustee, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts. (vi) The Trustee shall not be liable with respect to action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.5, and the Trustee shall be entitled from time to time to request such a direction. (b) Every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b) and (c) of this Section. (c) The Trustee shall be under no obligation and may refuse to perform any duty or exercise any right or power unless it receives indemnity satisfactory to it against any loss, liability or expense. No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties hereunder or in the 41

49 exercise of any of its rights or powers, if it shall have reasonable grounds to believe that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. (d) The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. SECTION 7.2 Rights of Trustee. Subject to Section 7.1: (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. The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney, to the extent reasonably required by such inquiry or investigation. (b) Before the Trustee acts or refrains from acting, it may require an Officers' Certificate or an Opinion of Counsel. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on such certificate or opinion. (c) The Trustee may act through agents and shall not be responsible for the misconduct or negligence of any agent appointed with due care. (d) The Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to be authorized or within its rights or powers. SECTION 7.3 Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or its Subsidiaries or Affiliates with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. However, the Trustee must comply with Sections 7.10 and 7.11. SECTION 7.4 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 42

50 any prospectus, offering or solicitation documents, and it shall not be responsible for any statement in the Securities other than its certificate of authentication. SECTION 7.5 Notice of Defaults. If a Default occurs and is continuing and if it is known to the Trustee, the Trustee shall mail to each Holder pursuant to Section 11.2 a notice of the Default within 90 days after it occurs. Except in the case of a Default in any payment on any Security, the Trustee may withhold the notice if and so long as the board of directors, executive committee or a trust committee of officers in good faith determines that withholding the notice is in the interests of Holders. SECTION 7.6 Reports by Trustee to Holders. Within 60 days after each May 15, beginning with the May 15 following the date of this Indenture, the Trustee shall mail to each Holder a brief report dated as of such May 15 that complies with TIA Section 313(a), but only if such report is required in any year under TIA Section 313(a). The Trustee also shall comply with TIA Sections 313(b) and 313(c). A copy of each report at the time of its mailing to Holders shall be filed with the SEC and each stock exchange on which the Securities are listed. The Company shall notify the Trustee in writing when the Securities become listed on any national securities exchange or of any delisting thereof. SECTION 7.7 Compensation and Indemnity. The Company and the Subsidiary Guarantors jointly and severally agree to pay the Trustee from time to time reasonable compensation for its services (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust). The Company and the Subsidiary Guarantors jointly and severally agree to reimburse the Trustee upon request for all reasonable out-of-pocket expenses, disbursements and advances incurred by it. Such expenses shall include when applicable the reasonable compensation and expenses of the Trustee's agents and counsel. The Trustee shall not be under any obligation to institute any suit, or take any remedial action under this Indenture, or to enter any appearance or in any way defend any suit in which it may be a defendant, or to take any steps in the execution of the trusts created hereby or thereby or in the enforcement of any rights and powers under this Indenture, until it shall be indemnified to its satisfaction against any and all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provisions of this Indenture, including compensation for services, costs, expenses, outlays, counsel fees and other disbursements, and against all liability not due to its negligence or willful misconduct. The Company and the Subsidiary Guarantors jointly and severally agree to indemnify the Trustee against any loss, liability or expenses incurred by it arising out of or in connection with the acceptance and administration of the trust and its duties 43

51 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 7.7) 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 7.7 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 6.1(8) or (9), the expenses and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law. SECTION 7.8 Replacement of Trustee. (i) 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: (ii) the Trustee fails to comply with Section 7.1; (iii) the Trustee is adjudged a bankrupt or an insolvent; (iv) a receiver or other public officer takes charge of the Trustee or its property; or (v) 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 44

52 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. 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 7.7, 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 7.9 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. 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. 45

53 ARTICLE VIII DISCHARGE OF INDENTURE SECTION 8.1 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 8.2 or 8.3 with respect to all outstanding Securities upon compliance with the conditions set forth below in this Article Eight. SECTION 8.2 Legal Defeasance and Discharge. Upon the Company's exercise under Section 8.1 of the option applicable to this Section 8.2, the Company and the Subsidiary Guarantors shall be deemed to have been discharged from their 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 8.5 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 8.4, 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 2.3, 2.4, 2.6, 2.7, 2.10 and 4.4, (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 7.7) and (d) this Article Eight. Subject to compliance with this Article Eight, the Company may exercise its option under this Section 8.2 notwithstanding the prior exercise of its option under Section 8.3 with respect to the Securities. SECTION 8.3 Covenant Defeasance. Upon the Company's exercise under Section 8.1 of the option applicable to this Section 8.3, the Company shall be released from its obligations under the covenants contained in Sections 4.7, 4.8, 4.9 and 4.10 and Article Five with respect to the outstanding Securities on and after the date the conditions set forth below are satisfied (hereinafter, "Covenant Defeasance"), and the Securities shall thereafter be deemed not "outstanding" for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed "outstanding" for all other purposes hereunder (it being understood that such Securities shall not be deemed outstanding for accounting purposes). For this 46

54 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 6.1(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 8.1 of the option applicable to this Section 8.3, Sections 6.1(4) through 6.1(9) shall not constitute Events of Default. SECTION 8.4 Conditions to Legal or Covenant Defeasance. The following shall be the conditions to application of either Section 8.2 or Section 8.3 to the outstanding Securities: (a) The Company shall irrevocably have deposited or cause to be deposited with the Trustee (or another trustee satisfying the requirements of Section 7.10 who shall agree to comply with the provisions of this Article Eight applicable to it) as trust funds in trust for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to, the benefit of the Holders of such Securities, (a) cash in U.S. Legal Tender in an amount, or (b) non-callable U.S. Government Securities which through the scheduled payment of principal and interest in respect thereof in accordance with their terms will provide, not later than one day before the due date of any payment, cash in U.S. Legal Tender in an amount, or (c) a combination thereof, in such amounts, as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge and which shall be applied by the Trustee (or other qualifying trustee) to pay and discharge the principal of, premium, if any, and interest on the outstanding Securities on the Maturity Date or on the applicable redemption date, as the case may be, of such principal or installment of principal, premium, if any, or interest and in accordance with the terms of this Indenture and of such Securities; provided that the Trustee shall have been irrevocably instructed to apply such money or the proceeds of such non- callable Government Securities to said payments with respect to the Securities. (b) In the case of an election under Section 8.2, 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; 47

55 (c) In the case of an election under Section 8.3, 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 6.1(8) or 6.1(9) is concerned, at any time in the period ending on the 91st day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period); (e) Such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, this 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 8.2 or 8.3, 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 8.2 or 8.3 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 8.2 or the Covenant Defeasance under Section 8.3 (as the case may be) have been complied with as contemplated by this Section 8.4. SECTION 8.5 Deposited Money and U.S. Government Securities to be Held in Trust; Other Miscellaneous Provisions. Subject to Section 8.6, all money and non-callable U.S. Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.5, the "Trustee") pursuant to Section 8.4 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 non-callable U.S. Government Securities deposited pursuant to Section 8.4 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. 48

56 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 non-callable U.S. Government Securities held by it as provided in Section 8.4 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 8.4(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 8.6 Repayment to Company. Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, premium, if any, or interest on any Security which is not subject to the last paragraph of Section 8.5 and has remained unclaimed for one year after such principal, and premium, if any, or interest has become due and payable shall be paid to the Company on its request 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 8.7 Reinstatement. If the Trustee or Paying Agent is unable to apply any U.S. Legal Tender or non-callable U.S. Government Securities in accordance with Section 8.2 or 8.3, 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 8.2 or 8.3 until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.2 or 8.3, 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. 49

57 ARTICLE IX AMENDMENTS, SUPPLEMENTS AND WAIVERS SECTION 9.1 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 5.1; (3) to reflect the addition or release of any Subsidiary Guarantor, as provided for by this Indenture; (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 9.6, 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 9.2 With Consent of Holders. Except as provided below in this Section 9.2, 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. 50

58 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 9.6, 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 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) waive a Default or Event of Default in the payment of the principal of, premium, if any, or interest on the Securities; (6) make any Security payable in money other than that stated in the Security; (7) impair the right to institute suit for the enforcement of principal of, premium, if any, or principal on any Security pursuant to Sections 6.7 or 6.8, except as limited by Section 6.6; or 51

59 (8) make any change in Section 6.4 or Section 6.7 or in this sentence of this Section 9.2. 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 9.3 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 9.4 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. 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 2.5, 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 (i) through (ix) of Section 9.2. In that case the amendment, supplement or waiver shall bind each Holder of a Security who has consented to it and 52

60 every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder's Security. SECTION 9.5 Notation on or Exchange of Securities. 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 9.6 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 X GUARANTEES SECTION 10.1 Unconditional Guarantee. Each Subsidiary Guarantor hereby, jointly and severally, unconditionally guarantees (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 10.5. 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 53

61 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 10.2 Subsidiary Guarantors May Consolidate, etc. on Certain Terms. (a) Subject to paragraph (b) of this Section 10.2, no Subsidiary Guarantor may consolidate or merge with or into (whether or not such Subsidiary Guarantor is the surviving entity or Person) another corporation, entity or Person unless (i) the entity or Person formed by or surviving any such consolidation or merger (if other than such Subsidiary Guarantor) assumes all the obligations of such Subsidiary Guarantor pursuant to a supplemental indenture, in a form reasonably satisfactory to the Trustee, under the Securities and this Indenture and (ii) immediately after such transaction, no Default or Event of Default exists. In connection with any consolidation or merger contemplated by this Section 10.2, 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 10.2(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, by way of merger, consolidation or otherwise, or a sale or other disposition of all of the Capital Stock of such Subsidiary Guarantor, then such Subsidiary Guarantor (in the event of a sale or other disposition, by way of such a merger, consolidation or otherwise, of all of the Capital Stock of such Subsidiary Guarantor) or the corporation acquiring the property (in the event of a sale or other disposition of all or substantially all of the assets of such Subsidiary Guarantor) will be released and relieved of any obligations under its Guarantees. 54

62 SECTION 10.3 Addition of Subsidiary Guarantors. (a) If any Subsidiary of the Company guarantees any Funded Indebtedness of the Company at any time subsequent to the Issue Date, then the Company shall (i) cause the Securities to be equally and ratably guaranteed by such Subsidiary, but only to the extent that the Securities are not already guaranteed by such Subsidiary on reasonably comparable terms and (ii) cause such Subsidiary to execute and deliver a supplemental indenture, in a form reasonably satisfactory to the Trustee, evidencing its provision of a guarantee pursuant to the terms hereof. (b) The Company agrees to cause each Subsidiary other than a Foreign 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. (c) Any Person that was not a Subsidiary Guarantor on the Issue Date may become a 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, binding and enforceable 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 10.4 Release of a Subsidiary Guarantor. (a) If, at any time while the Securities remain outstanding, none of the Company's then outstanding Pari Passu Indebtedness (other than the Securities) is guaranteed by a Restricted Subsidiary, such Restricted Subsidiary shall be released and relieved of its obligations under its Guarantee (which shall be terminated and cease to have any force and effect). For purposes of this Section 10.4(a) only, other Pari Passu Indebtedness shall not be deemed to be outstanding if, and as long as, all conditions to defeasance thereof have been satisfied, pursuant to defeasance provisions substantially similar to those set forth in Article Eight hereof. (b) Upon the sale or disposition of a Subsidiary Guarantor (or substantially all of its assets), which is otherwise in compliance with the terms of this Indenture, including but not limited to the provisions of Section 10.2, or if a Subsidiary ceases to be a Restricted Subsidiary, such Subsidiary shall be released and relieved of its obligations under its Guarantee (which shall terminate and cease to have any force and effect). The Trustee shall deliver an appropriate instrument evidencing such release upon receipt of a request by the Company accompanied by an Officers' Certificate and an Opinion of Counsel certifying that such sale or other disposition or cessation was made by the Company in accordance with the provisions of this Indenture. 55

63 (c) Any Subsidiary Guarantor not so released pursuant to this Article Ten remains liable for the full amount of principal of and interest on the Securities as provided in this Article Ten. SECTION 10.5 Limitation of Subsidiary Guarantor's Liability. Each Subsidiary Guarantor, and by its acceptance hereof each Holder, hereby confirms that it is the intention of all such parties that the guarantee by such Subsidiary Guarantor pursuant to its Guarantee not constitute a fraudulent transfer or conveyance for purposes of any federal or state law. To effectuate the foregoing intention, the Holders and each Subsidiary Guarantor hereby irrevocably agree that the obligations of each Subsidiary Guarantor under the Guarantee shall be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Subsidiary Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Subsidiary Guarantor in respect of the obligations of such other Subsidiary Guarantor under its Guarantee or pursuant to Section 10.6, result in the obligations of such Subsidiary Guarantor under the Guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal or state law. This Section 10.5 is for the benefit of the creditors of each Subsidiary Guarantor, and, for purposes of applicable fraudulent transfer and fraudulent conveyance law, any Indebtedness of a Subsidiary Guarantor pursuant to a bank credit facility shall be deemed to have been incurred prior to the incurrence by such Subsidiary Guarantor of its liability under the Guarantee. SECTION 10.6 Contribution. In order to provide for just and equitable contribution among the Subsidiary Guarantors, the Subsidiary Guarantors agree, inter se, that in the event any payment or distribution is made by any Subsidiary Guarantor (a "Funding Guarantor") under the Guarantee, such Funding Guarantor shall be entitled to a contribution from each other Subsidiary Guarantor in a pro rata amount based on the Adjusted Net Assets of each Subsidiary Guarantor (including the Funding Guarantor) for all payments, damages and expenses incurred by the Funding Guarantor in discharging the Company's obligations with respect to the Securities or any other Subsidiary Guarantor's obligations with respect to the Guarantee. SECTION 10.7 Execution and Delivery of Guarantee. To further evidence the Guarantees set forth in Section 10.1, each Subsidiary Guarantor hereby agrees that a notation relating to such Guarantee, in substantially the form of Exhibit A-1, shall be endorsed on each Security authenticated and delivered by the Trustee and executed by either manual or facsimile signature of one Officer of each Subsidiary Guarantor. Each of the Subsidiary Guarantors hereby agrees that its Guarantee set forth in Section 10.1 shall remain in full force and effect notwithstanding any failure to endorse on each Security a notation relating to such Guarantee. 56

64 If an Officer of a Subsidiary Guarantor whose signature is on this Indenture or a Security no longer holds that office at the time the Trustee authenticates such Security or at any time thereafter, such Subsidiary Guarantor's Guarantee of such Security shall be valid nevertheless. The delivery of any Security by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of any Guarantee set forth in this Indenture on behalf of the Subsidiary Guarantor. SECTION 10.8 Severability. In case any provision of this Guarantee shall be invalid, illegal or unenforceable, that portion of such provision that is not invalid, illegal or unenforceable shall remain in effect, and the validity, legality, and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

Chesapeake Energy Corporation, an Oklahoma corporation (the "Company"), promises to pay interest on the principal amount of this Security at 7 7/8% per annum from the Issue Date until maturity. The Company will pay interest semiannually on March 15 and September 15 of each year (each an "Interest Payment Date"), or if any such day is not a Business Day, on the next succeeding Business Day. Interest on the Securities will accrue from the most recent Interest Payment Date on which interest has been paid or, if no interest has been paid, from the Issue Date; provided, that if there is no existing Default in the payment of interest, and if this Security is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided, further, that the first Interest Payment Date shall be September 15, 1997. The Company shall pay interest on overdue principal and premium, if any, from time to time on demand at a rate equal to the interest rate on the Securities then in effect; it shall pay interest on overdue installments of interest (without regard to any applicable grace periods) from time to time on demand at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day year of twelve 30-day months. All references herein to interest shall include additional interest, if any, payable as Liquidated Damages pursuant to the Registration Rights Agreement. 2. Method of Payment. The Company will pay interest on the Securities to the persons who are registered holders of Securities at the close of business on the record date immediately preceding the Interest Payment Date, even if such Securities are canceled after the record date and on or before the Interest Payment Date.

The Company will pay principal of, premium, if any, and interest on the Securities in money of the United States of America that at the time of payment is legal tender for payment of public and private debts.

The Securities are limited to $150,000,000 aggregate principal amount. 5. Ranking and Guarantees. The Securities are general senior unsecured obligations of the Company.

Certain limitations to the obligations of the Subsidiary Guarantors are set forth in further detail in the Indenture. 6. Redemption at Make-Whole Price. At any time, the Company may, at its option, redeem all or any portion of the Securities at the Make-Whole Price plus accrued and unpaid interest to the date of redemption.

Notice of redemption will be mailed to the Holder's registered address at least 30 days but not more than 60 days before the redemption date to each Holder of Securities to be redeemed. If less than all Securities are to be redeemed, the Trustee shall select pro rata, by lot or, if the Securities are listed on any securities exchange, by any other method that the Trustee considers fair and appropriate and that complies with the requirements of such exchange; the Securities to be redeemed in multiples of $1,000; provided, however, that no Securities with a principal amount of $1,000 or less will be redeemed in part. Securities in denominations larger than $1,000 may be redeemed in part. On and after the redemption date, interest ceases to accrue on Securities or portions of them called for redemption (unless the Company shall default in the payment of the redemption price or accrued interest). 8.

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 and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Registrar need not transfer or exchange any A-5

76 Securities selected for redemption. Also, it need not transfer or exchange any Securities for a period of 15 days before a selection of Securities to be redeemed. 10. Persons Deemed Owners. The registered Holder of a Security may be treated as the owner of it for all purposes and neither the Company, any Subsidiary Guarantor, the Trustee nor any Agent shall be affected by notice to the contrary. 11. Unclaimed Money. If money for the payment of principal or interest remains unclaimed for one year, the Trustee or Paying Agent will pay the money back to the Company at its request. After that, all liability of the Trustee and such Paying Agent with respect to such money shall cease. 12. 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. 13. 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. 14. 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 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 relating to the Company, 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 A-6

77 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. 15.

The terms and provisions contained in the Securities and the Guarantee shall constitute, and are hereby expressly made, a part of this Indenture and, to the extent applicable, the Company and the Subsidiary Guarantors, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. 13

21 Securities offered and sold in their initial distribution in reliance on Regulation S may be initially issued in the form of temporary Global Securities in fully registered form without interest coupons, substantially in the form of Exhibit A, with such applicable legends as are provided for in Exhibit A hereto. Such temporary Global Securities may be registered in the name of the Depository or its nominee and deposited with the Trustee, as custodian for the Depository, duly executed by the Company and authenticated by the Trustee as hereinafter provided, for credit by the Depository to the respective accounts of the beneficial owners of the Securities represented thereby (or such other accounts as they may direct), provided that upon such deposit all such Securities shall be credited to or through accounts maintained at the Depository by or on behalf of Euroclear or CEDEL. Until such time as the Restricted Period (as defined below) shall have expired, any such temporary Global Securities, together with their Successor Securities which are Global Securities other than the Restricted Global Security, shall each be referred to herein as a "Temporary Regulation S Global Security." After such time as the Restricted Period shall have expired and the certifications referred to in the next succeeding paragraph shall have been provided, interests in such Temporary Regulation S Global Securities shall be exchanged for interests in like Global Securities, each referred to herein collectively as a "Permanent Regulation S Global Security," substantially in the form of Security set forth in Exhibit A, with such applicable legends as are provided for in Exhibit A. Such Permanent Regulation S Global Securities shall be registered in the name of the Depository or its nominee and deposited with the Trustee, as custodian for the Depository, duly executed by the Company and authenticated by the Trustee as hereinafter provided, for credit to the respective accounts of the beneficial owners of the Securities represented thereby (or such other accounts as they may direct). The aggregate principal amount of the Temporary Regulation S Global Security or the Permanent Regulation S Global Security may be increased or decreased from time to time by adjustments made on the records of the Trustee, as custodian for the Depository, as hereinafter provided. As used herein, the term "Restricted Period" means the period of 40 days commencing on the day after the latest of (a) the day on which the Securities are first offered to persons other than distributors (as defined in Regulation S) in reliance on Regulation S and (b) the Issue Date. Interests in a Temporary Regulation S Global Security may be exchanged for interests in a Permanent Regulation S Global Security only after (a) the expiration of the Restricted Period, (b) delivery by a beneficial owner of an interest therein to Euroclear or CEDEL of a written certification (an "Owner Securities Certification") substantially in the form of Exhibit C hereto, and (c) upon delivery by Euroclear or CEDEL to the Trustee of a written certification (a "Depository Securities Certification") substantially in the form attached hereto as Exhibit D. Upon satisfaction of such conditions, the Trustee will exchange the portion of the Temporary Regulation S Global Security covered by such certification for interests in a Permanent Regulation S Global Security. The delivery by such Holder of a beneficial interest in such Temporary Regulation S Global Security of such certification shall constitute an irrevocable instruction by such holder to Euroclear or CEDEL, as the case may be, to exchange such Holder's beneficial interest in the Temporary Regulation S Global Security for a beneficial interest in the Permanent Regulation S Global Security upon the expiration of the Restricted Period in accordance with the next succeeding paragraph. Upon: 14

22 (i) the expiration of the Restricted Period; (ii) receipt by Euroclear or CEDEL, as the case may be, of Owner Securities Certifications described in the preceding paragraph; (iii) receipt by the Depository of: (1) written instructions given in accordance with the Applicable Procedures from an Agent Member directing the Depository to credit or cause to be credited to a specified Agent Member's account a beneficial interest in a Permanent Regulation S Global Security in a principal amount equal to that of the beneficial interest in a corresponding Temporary Regulation S Global Security for which the necessary certifications have been delivered; and (2) a written order given in accordance with the Applicable Procedures containing information regarding the account of the Agent Member, and the Euroclear or CEDEL account for which such Agent Member's account is held, to be credited with, and the account of the Agent Member to be debited for, such beneficial interest; and (iv) receipt by the Trustee of notification from the Depository of the transactions described in (iii) above and from Euroclear or CEDEL, as the case may be, of Depository Securities Certifications, the Trustee, as Registrar (as defined below), shall instruct the Depository to reduce the principal amount of such Temporary Regulation S Global Security and to increase the principal amount of such Permanent Regulation S Global Security, by the principal amount of the beneficial interest in such Temporary Regulation S Global Security to be so transferred, and to credit or cause to be credited to the account of the person specified in such instructions a beneficial interest in such Permanent Regulation S Global Security having a principal amount equal to the amount by which the principal amount of such Temporary Regulation S Global Security was reduced upon such transfer. Securities offered and sold in their initial distribution in reliance on Rule 144A under the Securities Act and other than in reliance on Rule 144A under the Securities Act or Regulation S shall be issued in the form of one or more Global Securities (collectively, and, together with their Successor Securities, the "Restricted Global Security") in fully registered form without interest coupons, substantially in the form of Security set forth in Exhibit A hereto, with such applicable legends as are provided for in Exhibit A except as otherwise permitted herein. Such Restricted Global Security shall be registered in the name of the Depository or its nominee and deposited with the Trustee, as custodian for the Depository, duly executed by the Company and authenticated by the Trustee as hereinafter provided, for credit by the Depository to the respective accounts of beneficial owners of the securities represented thereby (or such other accounts as they may direct). 15

23 The aggregate principal amount of the Restricted Global Security may be increased or decreased from time to time by adjustments made on the records of the Trustee, as custodian for the Depository, in connection with a corresponding decrease or increase in the aggregate principal amount of the Temporary Regulation S Global Security or the Permanent Regulation S Global Security, as hereinafter provided. SECTION 2.2 Execution and Authentication. Two Officers of the Company shall sign the Securities on behalf of the Company, and one Officer of each Subsidiary Guarantor shall sign the notation on the Securities relating to the Guarantee of such Subsidiary Guarantor on behalf of such Subsidiary Guarantor, in each case by manual or facsimile signature. The Company's seal shall be reproduced on the Securities. If an Officer of the Company or any Subsidiary Guarantor whose signature is on a Security no longer holds that office at the time the Security is authenticated, the Security shall be valid nevertheless. A Security shall not be valid until the Trustee or an authenticating agent manually signs the certificate of authentication on the Security. The signature shall be conclusive evidence that the Security has been authenticated under this Indenture. The Trustee or an authenticating agent shall authenticate Securities for original issue in the aggregate principal amount of $150,000,000 upon a written order of the Company signed by two Officers of the Company. The aggregate principal amount of Securities outstanding at any time may not exceed $150,000,000. Series B Notes may be issued only in exchange for a like principal amount of Series A Notes pursuant to an Exchange Offer. The principal and interest on Book-Entry Securities shall be payable to the Depository or its nominee, as the case may be, as the sole registered owner and the sole holder of the Book-Entry Securities represented thereby. The principal and interest on Securities in certificated form shall be payable at the office of the Paying Agent. The Trustee may appoint an authenticating agent to authenticate Securities. An authenticating agent may authenticate Securities whenever the Trustee may do so except on original issuance. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with the Company or its Affiliates. The Securities shall be issuable only in registered form without coupons and only in denominations of $1,000 and any integral multiple thereof. 16

24 If the Securities are to be issued in the form of one or more Global Securities, then the Company shall execute and the Trustee shall authenticate and deliver one or more Global Securities that shall represent and shall be in minimum denominations of $1,000. SECTION 2.3 Registrar and Paying Agent. The Company shall maintain an office or agency where the 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. Where the Trustee is acting as or has been appointed Registrar and/or Paying Agent, the Company may appoint one or more co- registrars and one or more additional paying agents with the prior consent of the Trustee, whose consent shall not be unreasonably withheld. The term "Paying Agent" includes any additional paying agent. The Company shall enter into an appropriate agency agreement with any Agent not a party to this Indenture. Such agency agreement shall provide for reasonable compensation for such services. 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 or act as Registrar or Paying Agent, the Trustee shall act as such and shall be duly compensated therefor. The Registrar or a co-registrar and a Paying Agent shall be maintained by the Company in the Borough of Manhattan, the City of New York. The Company initially designates the Trustee as the Registrar and Paying Agent. The Company initially appoints the Trustee to act as the Registrar and Paying Agent and to act as Securities Custodian with respect to the Global Securities. SECTION 2.4 Paying Agent to Hold Money in Trust. The Company shall require each Paying Agent other than the Trustee to hold in trust for the benefit of Holders or the Trustee all money held by such Paying Agent for the payment of principal of, premium, if any, or interest on the Securities (whether such money shall have been paid to it by the Company or any Subsidiary Guarantor), and to notify the Trustee of any Default by the Company or any Subsidiary Guarantor in making any such payment. While any such Default continues, the Trustee may require the Paying Agent to pay all money held by it to the Trustee. Except as provided in the immediately preceding sentence, 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 and, if the Company requires such payment, the Company shall give prior notice to the Trustee and provide appropriate money transfer instructions to the Paying Agent. Upon such payment over to the Trustee and accounting for any funds disbursed, such Paying Agent (if other than the Company or a Subsidiary) shall have no further liability for the money. If the Company or a Subsidiary acts as Paying Agent, 17

25 it shall segregate and hold as separate trust funds for the benefit of the Holders all money held by it as Paying Agent. SECTION 2.5 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 and shall otherwise comply with TIA Section 312(a). If the Trustee is not the Registrar, the Company shall furnish or cause to be furnished to the Trustee at least ten Business Days prior to each semiannual 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, and the Company shall otherwise comply with TIA Section 312(a). SECTION 2.6 Transfer and Exchange. (a) Beneficial interests in a Global Security may, subject to the restrictions on the transferability of the Securities and upon delivery of a certificate in the form of Exhibit B hereto be exchanged for certificated Securities upon request but only upon at least 20 days' prior written notice given to the Trustee by or on behalf of the Depository (in accordance with the Depository's customary procedures) and will bear the applicable legends set forth in Exhibit A hereto. (b) If any Global Security is to be exchanged for other Securities or canceled in whole, it shall be surrendered by or on behalf of the Depository or its nominee to the Trustee, as Registrar, for exchange or cancellation as provided in this Article II. If any Global Security is to be exchanged for other Securities or cancelled in part, or if another Security is to be exchanged in whole or in part for a beneficial interest in any Global Security, such Global Security shall be so surrendered for exchange or cancellation as provided in this Article II or, if the Trustee is acting as custodian for the Depository or its nominee (or is party to a similar arrangement) with respect to such Global Security, the principal amount thereof shall be reduced or increased by an amount equal to the portion thereof to be so exchanged or cancelled, or the principal amount of such other Security to be so exchanged for a beneficial interest therein, as the case may be, in each case by means of an appropriate adjustment made on the records of the Trustee, whereupon the Trustee, in accordance with the Applicable Procedures, shall instruct the Depository or its authorized representatives to make a corresponding adjustment to its records (including by crediting or debiting any Agent Member's account as necessary to reflect any transfer or exchange of a beneficial interest). Upon any such surrender or adjustment of a Global Security, the Trustee shall, subject to this Article II, authenticate and deliver any Securities issuable in exchange for such Global Security (or any portion thereof) to or upon the order of, and registered in such names as may be directed by, the Depository or its authorized representative. Upon the request of the Trustee in connection with the occurrence of any of the events specified in the preceding paragraph or in clause (r) below, the Company shall promptly make available to the Trustee a reasonable supply of Securities that are not in the form of Global Securities. The Trustee shall be entitled to rely upon any order, direction or request of the 18

26 Depository or its authorized representative which is given or made pursuant to this Article II if such order, direction or request is given or made in accordance with the Applicable Procedures. (c) Subject to the provisions in the legends required by this Indenture, the registered Holder may grant proxies and otherwise authorize any Person, including Agent Members and Persons who may hold interests in Agent Members to take any action that such Holder is entitled to take under this Indenture. (d) Neither Agent Members nor any other Person on whose behalf Agent Members may act shall have any rights under this Indenture with respect to any Global Security held on their behalf by the Depository or under the Global Security, and the Depository may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depository or impair, as between the Depository and its Agent Members, the operation of customary practice governing the exercise of the rights of a Holder of any Security. With respect to any Global Security deposited with the Trustee as custodian for the Depository for credit to their respective accounts (or to such other accounts as they may direct) at Euroclear or CEDEL, the provisions of the "Operating Procedures of the Euroclear System" and the "Terms and Conditions Governing Use of Euroclear," and the "Management Regulations" and "Instructions to Participants" of CEDEL, respectively, shall be applicable to such Global Security. (e) Upon presentation for transfer and exchange of any Security at the office of the Trustee, as Registrar, located in The City of New York, accompanied by a written instrument of transfer or exchange in the form approved by the Company (it being understood that, until notice to the contrary is given to holders of Securities, the Company shall be deemed to have approved the form of instrument of transfer or exchange, if any, printed on any Security), executed by the registered Holder, in person or by such Holder's attorney thereunto duly authorized in writing, and upon compliance with this Section 2.6, such Security shall be transferred upon the Register, and a new Security shall be authenticated and issued in the name of the transferee. Notwithstanding any provision to the contrary herein or in the Securities, transfers of a Global Security, in whole or in part, and transfers of interests therein of the kind described in this Section 2.6, shall only be made in accordance with this Section 2.6. Transfers and exchanges subject to this Section 2.6 shall also be subject to the other provisions of this Indenture that are not inconsistent with this Section 2.6. (f) General. A Global Security may not be transferred, in whole or in part, to any Person other than the Depository or a nominee thereof, and no such transfer to any such other Person may be registered; provided, however, that this clause (f) shall not prohibit any transfer of a Security that is issued in exchange for a Global Security but is not itself a Global Security. No transfer of a Security to any Person shall be effective under this Indenture or the Securities unless and until such Security has been registered in the name of such Person. Nothing in this clause (f) shall prohibit or 19

27 render ineffective any transfer of a beneficial interest in a Global Security effected in accordance with the other provisions of this Section 2.6. (g) Temporary Regulation S Global Security. If the holder of a beneficial interest in a Temporary Regulation S Global Security wishes at any time to transfer such interest to a Person who wishes to take delivery thereof in the form of a beneficial interest in such Temporary Regulation S Global Security, such transfer may be effected, subject to the rules and procedures of the Depository, Euroclear and CEDEL, in each case to the extent applicable and as in effect from time to time (the "Applicable Procedures"), only in accordance with this clause (g). Upon delivery (i) by a beneficial owner of an interest in a Temporary Regulation S Global Security to Euroclear or CEDEL, as the case may be, of an Owner Securities Certification, (ii) by the transferee of such beneficial interest in the Temporary Regulation S Global Security to Euroclear or CEDEL, as the case may be, of a written certification (a "Transferee Securities Certification") substantially in the form of Exhibit E hereto and (iii) by Euroclear or CEDEL, as the case may be, to the Trustee, as Registrar, of a Depository Securities Certification, the Trustee may direct either Euroclear or CEDEL, as the case may be, to reflect on its records the transfer of a beneficial interest in the Temporary Regulation S Global Security from the beneficial owner providing the Owner Securities Certification to the Person providing the Transferee Securities Certification. (h) Restricted Global Security to Temporary Regulation S Global Security. If the holder of a beneficial interest in the Restricted Global Security wishes at any time to transfer such interest to a Person who wishes to take delivery thereof in the form of a beneficial interest in the Temporary Regulation S Global Security, such transfer may be effected, subject to the Applicable Procedures, only in accordance with the provisions of this clause (h) and clause (n) below. Upon receipt by the Trustee, as Registrar, of (A) written instructions given by or on behalf of the Depository in accordance with the Applicable Procedures directing the Trustee to credit or cause to be credited to a specified Agent Member's account a beneficial interest in the Temporary Regulation S Global Security in a specified principal amount and to cause to be debited from another specified Agent Member's account a beneficial interest in the Restricted Global Security in an equal principal amount and (B) a certificate in substantially the form set forth in Exhibit F hereto signed by or on behalf of the holder of such beneficial interest in the Restricted Global Security, the Trustee, as Registrar, shall, subject to clause (n) below, reduce the principal amount of the Restricted Global Security, and increase the principal amount of the Temporary Regulation S Global Security by such specified principal amount. (i) Restricted Global Security to Permanent Regulation S Global Security. If the holder of a beneficial interest in the Restricted Global Security wishes at any time to transfer such interest to a Person who wishes to take delivery thereof in the form of a beneficial interest in the Permanent Regulation S Global Security, such transfer may be effected, subject to the Applicable Procedures, only in accordance with this clause (i). Upon receipt by the Trustee, as Registrar, of (A) written instructions given by or on behalf of the Depository in accordance with the Applicable Procedures directing the Trustee to credit or cause to be credited to a specified Agent Member's account a beneficial interest in the Permanent Regulation S Global Security in a specified principal 20

28 amount and to cause to be debited from another specified Agent Member's account a beneficial interest in the Restricted Global Security in an equal principal amount and (B) a certificate in substantially the form set forth in Exhibit G hereto signed by or on behalf of the holder of such beneficial interest in the Restricted Global Security, the Trustee, as Registrar, shall reduce the principal amount of a Restricted Global Security, and increase the principal amount of the Permanent Regulation S Global Security by such specified principal amount. (j) Temporary Regulation S Global Security or Permanent Regulation S Global Security to Restricted Global Security. If the holder of a beneficial interest in the Temporary Regulation S Global Security or the Permanent Regulation S Global Security at any time, wishes to transfer such interest to a Person who wishes to take delivery thereof in the form of a beneficial interest in the Restricted Global Security, such transfer may be effected, subject to the Applicable Procedures, only in accordance with this clause (j) and clause (n) below; provided, that with respect to any transfer of a beneficial interest in a Temporary Regulation S Global Security, the transferor and Euroclear or CEDEL, as the case may be, must have previously delivered an Owner Securities Certification and a Depository Securities Certification respectively, with respect to such beneficial interest. Upon receipt by the Trustee, as Registrar, of (A) written instructions given by or on behalf of the Depository in accordance with the Applicable Procedures directing the Trustee to credit or cause to be credited, to a specified Agent Member's account a beneficial interest in the Restricted Global Security in a specified principal amount and to cause to be debited from another specified Agent Member's account a beneficial interest in the Temporary Regulation S Global Security or the Permanent Regulation S Global Security, as the case may be, in an equal principal amount and (B) a certificate in substantially the form set forth in Exhibit H signed by or on behalf of the holder of such beneficial interest in the Temporary Regulation S Global Security or the Permanent Regulation S Global Security, as the case may be, the Trustee, as Security Registrar, shall, subject to clause (n) below, reduce the principal amount of such Temporary Regulation S Global Security or Permanent Regulation S Global Security, as the case may be, and increase the principal amount of the Restricted Global Security by such specified principal amount. (k) Non-Global Restricted Security to Restricted Global Security. If the holder of a Restricted Security (other than a Global Security) wishes at any time to transfer all or any portion of such Security to a Person who wishes to take delivery thereof in the form of a beneficial interest in the Restricted Global Security, the Temporary Regulation S Global Security or the Permanent Regulation S Global Security, such transfer may be effected, subject to the Applicable Procedures, only in accordance with this clause (k) and clause (n) below. Upon receipt by the Trustee, as Registrar, of (A) such Security and written instructions given by or on behalf of such Holder as provided in this Section 2.6 directing the Trustee to credit or cause to be credited to a specified Agent Member's account a beneficial interest in the Restricted Global Security, the Temporary Regulation S Global Security or the Permanent Regulation S Global Security, as the case may be, in a specified principal amount equal to the principal amount of the Restricted Security (or portion thereof) to be so transferred, and (B) an appropriately completed certificate substantially in the form set forth in Exhibit I-1 hereto, if the specified account is to be credited with a beneficial interest in the Restricted Global Security, or Exhibit I-2 herein, if the specified account is to be 21

29 credited with a beneficial interest in the Temporary Regulation S Global Security or the Permanent Regulation S Global Security, signed by or on behalf of such Holder, then the Trustee, as Registrar, shall, subject to clause (n) below, cancel such Restricted Security (and issue a new Security in respect of any untransferred portion thereof) as provided in this Section 2.6 and increase the principal amount of the Restricted Global Security, Temporary Regulation S Global Security or Permanent Regulation S Global Security, as the case may be, by the specified principal amount. (l) Non-Global Permanent Regulation S Security to Restricted Global Security or Permanent Regulation S Global Security. If the Holder of a Permanent Regulation S Security (other than a Global Security) wishes at any time to transfer all or any portion of such Security to a Person who wishes to take delivery thereof in the form of a beneficial interest in the Restricted Global Security or the Permanent Regulation S Global Security, as the case may be, such transfer may be effected only in accordance with this clause (1) and subject to the Applicable Procedures. Upon receipt by the Trustee, as Registrar, of (A) such Security and instructions given by or on behalf of such Holder as provided in this Section 2.6 directing the Trustee to credit or cause to be credited to a specified Agent Member's account a beneficial interest in the Restricted Global Security or the Permanent Regulation S Global Security, as the case may be, in a principal amount equal to the principal amount of the Security (or portion thereof) to be so transferred, and (B) (i) with respect to a transfer which is to be delivered in the form of a beneficial interest in the Restricted Global Security, a certificate in substantially the form set forth in Exhibit J-1 hereto, signed by or on behalf of such Holder, and (ii) with respect to a transfer which is to be delivered in the form of a beneficial interest in the Permanent Regulation S Global Security, a certificate in substantially the form set forth in Exhibit J-2 hereto, signed by or on behalf of such Holder, then the Trustee, as Registrar, shall, subject to clause (q) below, cancel such Security (and issue a new Security in respect of any untransferred portion thereof) as provided in this Section 2.6 and increase the principal amount of the Restricted Global Security, or the Permanent Regulation S Global Security, as the case may be, by the specified principal. (m) Other Exchanges. Securities that are not Global Securities may be exchanged (on transfer or otherwise) for Securities that are not Global Securities or for beneficial interests in a Global Security (if any is then outstanding) only in accordance with such procedures, which shall be substantially consistent with the provisions of clauses (f) through (l) above (including the certification requirements intended to insure that transfers of beneficial interests in a Global Security comply with Rule 144A under the Securities Act or Regulation S, as the case may be) and any Applicable Procedures, as may from time to time be adopted by the Company and the Trustee. (n) Interests in Temporary Regulation S Global Security to be Held Through Euroclear or CEDEL. Until the later of the expiration of the Restricted Period and the provision of the Owner Securities Certification and the Depository Securities Certification, beneficial interests in any Temporary Regulation S Global Security may be held only in or through accounts maintained at the Depository by Euroclear or CEDEL (or by Agent Members acting for the account thereof). 22

30 (o) When Securities in certificated form are presented to the Registrar with a request to register the transfer of such Securities or to exchange such Securities for an equal principal amount of Securities of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested if its requirements for such transaction are met; provided, however, that the Securities surrendered for transfer or exchange shall be duly endorsed or accompanied by a written instrument of transfer in form satisfactory to the Company and the Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing. To permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate Securities at the Registrar's request. No service charge shall be made for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchanges or transfers pursuant to Sections 2.2, 2.10, 3.7 or 9.5). The Registrar shall not be required to register the transfer of or exchange of any Security (i) during a period beginning at the opening of business 15 days before the mailing of a notice of redemption of Securities and ending at the close of business on the day of such mailing and (ii) selected for redemption in whole or in part pursuant to Article Three, except the unredeemed portion of any Security being redeemed in part. (p) If a Series A Note is a Restricted Security in certificated form, then as provided in this Indenture and subject to the limitations herein set forth, the Holder, provided it is a Qualified Institutional Buyer or an institutional "accredited investor" (as defined in Rule 501(a)(1), (2), (3) or (7) under the Securities Act), may exchange such Security for a Book-Entry Security by instructing the Trustee (by completing the Transferee Certificate in the form of Exhibit B hereto) to arrange for such Series A Note to be represented by a beneficial interest in a Global Security in accordance with the customary procedures of the Depository. (q) Upon any exchange provided for in Section 2.6(a), the Company shall execute and the Trustee shall authenticate, and deliver to the person specified by the Depository a new Series A Note or Notes registered in such names and in such authorized denominations as the Depository, pursuant to the instructions of the beneficial owner of the Securities requesting the exchange, shall instruct the Trustee. Thereupon, the beneficial ownership of such Global Security shown on the records maintained by the Depository or its nominee shall be reduced by the amounts so exchanged and an appropriate endorsement be made by and on behalf of the Trustee on the Global Security. Any such exchange shall be effected through the Depository in accordance with the procedures of the Depository therefor. (r) Notwithstanding the foregoing, no Global Security shall be registered for transfer or exchange, or authenticated and delivered, whether pursuant to this Section, Section 2.7, 2.10 or 3.7 or otherwise , in the name of a person other than the Depository for such Global Security or its nominee until (i) the Depository notifies the Company that it is unwilling or unable to continue as Depository for such Global Security or if at any time the Depository ceases to be a clearing agency registered under the Exchange Act, and a successor depository is not appointed by the Company within 30 days, (ii) the Company executes and delivers to the Trustee a Company order 23

31 that all such Global Securities shall be exchangeable or (iii) there shall have occurred and be continuing an Event of Default. Upon the occurrence in respect of any Global Security representing the Series A Notes of any one or more of the conditions specified in clause (i), (ii) or (iii) of the preceding sentence, such Global Security may be registered for transfer or exchange for Series A Notes registered in the names of, authenticated and delivered to, such persons as the Trustee or the Depository, as the case may be, shall direct. (s) Except as provided above, any Security authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, any Global Security, whether pursuant to this Section 2.7, 2.10 or 3.7 or otherwise, shall also be a Global Security and bear the legend specified in footnote 1 to Exhibit A. SECTION 2.7 Replacement Securities. If a mutilated Security is surrendered to the Trustee 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 the Trustee are met. An indemnity bond may be required by the Trustee, the Company or any Subsidiary Guarantor that is sufficient in the judgment of the Company, the Subsidiary Guarantors and the Trustee to protect the Company, the Subsidiary Guarantors, the Trustee or any Agent from any loss which any of them may suffer if a Security is replaced. The Company may charge for its expenses (including fees and expenses of the Trustee) in replacing a Security. SECTION 2.8 Outstanding Securities. Senior Notes outstanding at any time are all Securities authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Security effected by the Trustee in accordance with the provisions hereof, and those described in this Section 2.8 as not outstanding. Except as set forth in Section 2.9, a Security does not cease to be outstanding because the Company, the Subsidiary Guarantors or any of their respective Subsidiaries or Affiliates holds the Security. If a Security is replaced pursuant to Section 2.7, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Security is held by a bona fide purchaser. If the principal amount of any Security is considered paid under Section 4.1, it ceases to be outstanding and interest on it ceases to accrue. SECTION 2.9 Treasury Securities. In determining whether the Holders of the required principal amount of Securities have concurred in any direction, waiver or consent, Securities owned by the Company, any Subsidiary Guarantor or an Affiliate of the Company shall be considered as though they are not outstanding, 24

32 except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Securities which the Trustee knows are so owned shall be so disregarded. SECTION 2.10 Temporary Securities. Until definitive Securities are ready for delivery, the Company may prepare and, upon written order of the Company, 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 and deliver definitive Securities in exchange for a like principal amount of temporary Securities surrendered to it. Until so exchanged, temporary Securities shall in all respects be entitled to the same benefits under this Indenture as definitive Securities. SECTION 2.11 Cancellation. The Company or any Subsidiary Guarantor at any time may deliver Securities to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any Securities surrendered to them for transfer, exchange or payment. The Trustee shall cancel all Securities surrendered for registration, transfer, exchange, payment or cancellation and shall destroy canceled Securities unless the Company directs their return to the Company. Except as provided in Section 2.7, the Company may not issue new Securities to replace Securities that it has paid or delivered to the Trustee for cancellation. Securities that are redeemed by the Company or that are otherwise acquired by the Company, will be surrendered to the Trustee for cancellation. SECTION 2.12 Defaulted Interest. If the Company defaults in a payment of interest on the Securities, it shall pay, or cause the Paying Agent to pay, the defaulted interest in any lawful manner (plus interest on such defaulted interest to the extent lawful) (taken together, the "Defaulted Interest") to the persons who are Holders on a subsequent special record date, in each case at the rate provided in the Securities and in Section 4.1 hereof. At least 15 days before the special record date, the Company shall mail to each Holder a notice stating the special record date, the payment date and the amount of Defaulted Interest to be paid. In the event that the Company has elected to cause a Paying Agent to pay the Defaulted Interest, the Company shall so notify the Paying Agent at least 15 days before the special record date, which notice shall also set forth the special record date, the payment date and the aggregate amount of Defaulted Interest to be paid. At least five days before such payment date, the Company shall deposit with the Paying Agent money sufficient to pay all of the Defaulted Interest on the payment date therefor and instruct the Paying Agent in writing to pay to specified Holders on the payment date.

None of the Company, the Trustee, any Paying Agent or any authenticating agent shall be affected by any notice to the contrary. ARTICLE III REDEMPTION SECTION 3.1 Notice to Trustee. If the Company elects to redeem Securities pursuant to the optional redemption provisions of Paragraphs 6, 7 or 8 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.

44 (3) default by the Company or any Subsidiary Guarantor in the deposit of any optional redemption payment, when and as due and payable pursuant to Article Three; (4) default on any other Indebtedness of the Company, any Subsidiary Guarantor or any other Restricted Subsidiary if either (A) such default results in the acceleration of the maturity of any such Indebtedness having a principal amount of $10.0 million or more individually or, taken together with the principal amount of any other such Indebtedness the maturity of which has been so accelerated, in the aggregate, or (B) such default results from the failure to pay when due principal of, premium, if any, or interest on, any such Indebtedness, after giving effect to any applicable grace period (a "Payment Default"), having a principal amount of $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 Article V, or in the performance, or breach of, any other covenant or agreement of the Company or any Subsidiary Guarantor in this Indenture and failure to remedy such default within a period of 45 days after written notice thereof from the Trustee or Holders of 25% of the principal amount of the outstanding Securities; (6) the entry by a court of one or more judgments or orders for the payment of money against the Company, any Subsidiary Guarantor or any other Restricted Subsidiary 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) a Guarantee by a Subsidiary Guarantor shall cease to be in full force and effect (other than a release of a Guarantee in accordance with Section 10.4) or any Subsidiary Guarantor shall deny or disaffirm its obligations with respect thereto; (8) the Company or any Restricted Subsidiary pursuant to or within the meaning of any Bankruptcy Law: (A) commences a voluntary case or proceeding, (B) consents to the entry of an order for relief against it in an involuntary case or proceeding, (C) consents to the appointment of a Custodian of it or for all or substantially all of its property, 37

45 (D) makes a general assignment for the benefit of its creditors, or (E) admits in writing that it generally is unable to pay its debts as the same become due; or (9) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: (A) is for relief (with respect to the petition commencing such case) against the Company or any Restricted Subsidiary in an involuntary case or proceeding, (B) appoints a Custodian of the Company or any Restricted Subsidiary or for all or substantially all of its property, or (C) orders the liquidation of the Company or any Restricted Subsidiary, and the order or decree remains unstayed and in effect for 60 days. The term "Bankruptcy Law" means Title 11, U.S. Code or any similar federal or state law for the relief of debtors. The term "Custodian" means any receiver, trustee, assignee, liquidator or similar official under any Bankruptcy Law. SECTION 6.2 Acceleration. If an Event of Default (other than an Event of Default specified in clauses 8 or 9) under Section 6.1 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 38

46 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 6.3 Other Remedies. If an Event of Default occurs and is continuing, the Trustee may, but is not obligated to, pursue, in its own name and as trustee of an express trust, any available remedy by proceeding at law or in equity to collect the payment of principal or interest on the Securities or to enforce the performance of any provision of the Securities or this Indenture. If an Event of Default specified under clauses (8) or (9) of Section 6.1 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 6.4 Waiver of Past Defaults. Subject to Sections 6.7 and 9.2, 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 6.5 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. 39

47 SECTION 6.6 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 (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 6.7 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 6.8 Collection Suit by Trustee. If an Event of Default in payment of principal, premium, if any, or interest specified in Section 6.1(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 40

48 of collection, including the reasonable compensation and expenses of the Trustee, its agents and counsel. SECTION 6.9 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 7.7; Second: to Holders for amounts due and unpaid on the Securities for principal and interest, ratably, without preference or priority of any kind, according to the amounts due and payable on the Securities for principal and interest, respectively; and Third: To the Company. The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 6.10. SECTION 6.11 Undertaking for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys' fees, 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 6.7, or a suit by Holders of more than 10% in principal amount of the then outstanding Securities. 41

49 ARTICLE VII TRUSTEE SECTION 7.1 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. Except during the continuance of an Event of Default: (i) The Trustee need perform only those duties that are specifically set forth (or incorporated by reference) in this Indenture and no others. (ii) In the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, the Trustee shall examine such certificates and opinions to determine whether or not they conform to the requirements of this Indenture. (iii) The Trustee may not be relieved from liability for its own negligent action, its own negligent failure to act, or its own willful misconduct, except that: (iv) This paragraph (c) does not limit the effect of paragraph (b) of this Section. (v) The Trustee shall not be liable for any error of judgment made in good faith by an officer of the Trustee, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts. (vi) The Trustee shall not be liable with respect to action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.5, and the Trustee shall be entitled from time to time to request such a direction. (b) Every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b) and (c) of this Section. (c) The Trustee shall be under no obligation and may refuse to perform any duty or exercise any right or power unless it receives indemnity satisfactory to it against any loss, liability or expense. No provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur financial liability in the performance of any of its duties hereunder or in the 42

50 exercise of any of its rights or powers, if it shall have reasonable grounds to believe that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. (d) The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. SECTION 7.2 Rights of Trustee. Subject to Section 7.1: (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. The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney, to the extent reasonably required by such inquiry or investigation. (b) Before the Trustee acts or refrains from acting, it may require an Officers' Certificate or an Opinion of Counsel. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on such certificate or opinion. (c) The Trustee may act through agents and shall not be responsible for the misconduct or negligence of any agent appointed with due care. (d) The Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to be authorized or within its rights or powers. SECTION 7.3 Individual Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or its Subsidiaries or Affiliates with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. However, the Trustee must comply with Sections 7.10 and 7.11. SECTION 7.4 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 43

51 any prospectus, offering or solicitation documents, and it shall not be responsible for any statement in the Securities other than its certificate of authentication. SECTION 7.5 Notice of Defaults. If a Default occurs and is continuing and if it is known to the Trustee, the Trustee shall mail to each Holder pursuant to Section 11.2 a notice of the Default within 90 days after it occurs. Except in the case of a Default in any payment on any Security, the Trustee may withhold the notice if and so long as the board of directors, executive committee or a trust committee of officers in good faith determines that withholding the notice is in the interests of Holders. SECTION 7.6 Reports by Trustee to Holders. Within 60 days after each May 15, beginning with the May 15 following the date of this Indenture, the Trustee shall mail to each Holder a brief report dated as of such May 15 that complies with TIA Section 313(a), but only if such report is required in any year under TIA Section 313(a). The Trustee also shall comply with TIA Sections 313(b) and 313(c). A copy of each report at the time of its mailing to Holders shall be filed with the SEC and each stock exchange on which the Securities are listed. The Company shall notify the Trustee in writing when the Securities become listed on any national securities exchange or of any delisting thereof. SECTION 7.7 Compensation and Indemnity. The Company and the Subsidiary Guarantors jointly and severally agree to pay the Trustee from time to time reasonable compensation for its services (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust). The Company and the Subsidiary Guarantors jointly and severally agree to reimburse the Trustee upon request for all reasonable out-of-pocket expenses, disbursements and advances incurred by it. Such expenses shall include when applicable the reasonable compensation and expenses of the Trustee's agents and counsel. The Trustee shall not be under any obligation to institute any suit, or take any remedial action under this Indenture, or to enter any appearance or in any way defend any suit in which it may be a defendant, or to take any steps in the execution of the trusts created hereby or thereby or in the enforcement of any rights and powers under this Indenture, until it shall be indemnified to its satisfaction against any and all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provisions of this Indenture, including compensation for services, costs, expenses, outlays, counsel fees and other disbursements, and against all liability not due to its negligence or willful misconduct. The Company and the Subsidiary Guarantors jointly and severally agree to indemnify the Trustee against any loss, liability or expenses incurred by it arising out of or in connection with the acceptance and administration of the trust and its duties 44

52 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 7.7) 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 7.7 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 6.1(8) or (9), the expenses and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law. SECTION 7.8 Replacement of Trustee. (i) 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: (ii) the Trustee fails to comply with Section 7.1; (iii) the Trustee is adjudged a bankrupt or an insolvent; (iv) a receiver or other public officer takes charge of the Trustee or its property; or (v) 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 45

53 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. 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 7.7, 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 7.9 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. 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. 46

54 ARTICLE VIII DISCHARGE OF INDENTURE SECTION 8.1 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 8.2 or 8.3 with respect to all outstanding Securities upon compliance with the conditions set forth below in this Article Eight. SECTION 8.2 Legal Defeasance and Discharge. Upon the Company's exercise under Section 8.1 of the option applicable to this Section 8.2, the Company and the Subsidiary Guarantors shall be deemed to have been discharged from their 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 8.5 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 8.4, 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 2.3, 2.4, 2.6, 2.7, 2.10 and 4.4, (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 7.7) and (d) this Article Eight. Subject to compliance with this Article Eight, the Company may exercise its option under this Section 8.2 notwithstanding the prior exercise of its option under Section 8.3 with respect to the Securities. SECTION 8.3 Covenant Defeasance. Upon the Company's exercise under Section 8.1 of the option applicable to this Section 8.3, the Company shall be released from its obligations under the covenants contained in Sections 4.7, 4.8, 4.9 and 4.10 and Article Five with respect to the outstanding Securities on and after the date the conditions set forth below are satisfied (hereinafter, "Covenant Defeasance"), and the Securities shall thereafter be deemed not "outstanding" for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed "outstanding" for all other purposes hereunder (it being understood that such Securities shall not be deemed outstanding for accounting purposes). For this 47

55 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 6.1(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 8.1 of the option applicable to this Section 8.3, Sections 6.1(4) through 6.1(9) shall not constitute Events of Default. SECTION 8.4 Conditions to Legal or Covenant Defeasance. The following shall be the conditions to application of either Section 8.2 or Section 8.3 to the outstanding Securities: (a) The Company shall irrevocably have deposited or cause to be deposited with the Trustee (or another trustee satisfying the requirements of Section 7.10 who shall agree to comply with the provisions of this Article Eight applicable to it) as trust funds in trust for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to, the benefit of the Holders of such Securities, (a) cash in U.S. Legal Tender in an amount, or (b) non-callable U.S. Government Securities which through the scheduled payment of principal and interest in respect thereof in accordance with their terms will provide, not later than one day before the due date of any payment, cash in U.S. Legal Tender in an amount, or (c) a combination thereof, in such amounts, as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge and which shall be applied by the Trustee (or other qualifying trustee) to pay and discharge the principal of, premium, if any, and interest on the outstanding Securities on the Maturity Date or on the applicable redemption date, as the case may be, of such principal or installment of principal, premium, if any, or interest and in accordance with the terms of this Indenture and of such Securities; provided that the Trustee shall have been irrevocably instructed to apply such money or the proceeds of such non- callable Government Securities to said payments with respect to the Securities. (b) In the case of an election under Section 8.2, 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; 48

56 (c) In the case of an election under Section 8.3, 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 6.1(8) or 6.1(9) is concerned, at any time in the period ending on the 91st day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period); (e) Such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, this 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 8.2 or 8.3, 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 8.2 or 8.3 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 8.2 or the Covenant Defeasance under Section 8.3 (as the case may be) have been complied with as contemplated by this Section 8.4. SECTION 8.5 Deposited Money and U.S. Government Securities to be Held in Trust; Other Miscellaneous Provisions. Subject to Section 8.6, all money and non-callable U.S. Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.5, the "Trustee") pursuant to Section 8.4 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 non-callable U.S. Government Securities deposited pursuant to Section 8.4 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. 49

57 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 non-callable U.S. Government Securities held by it as provided in Section 8.4 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 8.4(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 8.6 Repayment to Company. Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, premium, if any, or interest on any Security which is not subject to the last paragraph of Section 8.5 and has remained unclaimed for one year after such principal, and premium, if any, or interest has become due and payable shall be paid to the Company on its request 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 8.7 Reinstatement. If the Trustee or Paying Agent is unable to apply any U.S. Legal Tender or non-callable U.S. Government Securities in accordance with Section 8.2 or 8.3, 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 8.2 or 8.3 until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.2 or 8.3, 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. 50

58 ARTICLE IX AMENDMENTS, SUPPLEMENTS AND WAIVERS SECTION 9.1 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 5.1; (3) to reflect the addition or release of any Subsidiary Guarantor, as provided for by this Indenture; (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 9.6, 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 9.2 With Consent of Holders. Except as provided below in this Section 9.2, 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. 51

59 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 9.6, 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 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) waive a Default or Event of Default in the payment of the principal of, premium, if any, or interest on the Securities; (6) make any Security payable in money other than that stated in the Security; (7) impair the right to institute suit for the enforcement of principal of, premium, if any, or principal on any Security pursuant to Sections 6.7 or 6.8, except as limited by Section 6.6; or 52

60 (8) make any change in Section 6.4 or Section 6.7 or in this sentence of this Section 9.2. 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 9.3 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 9.4 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. 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 2.5, 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 (i) through (ix) of Section 9.2. In that case the amendment, supplement or waiver shall bind each Holder of a Security who has consented to it and 53

61 every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder's Security. SECTION 9.5 Notation on or Exchange of Securities. 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 9.6 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 X GUARANTEES SECTION 10.1 Unconditional Guarantee. Each Subsidiary Guarantor hereby, jointly and severally, unconditionally guarantees (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 10.5. 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 54

62 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 10.2 Subsidiary Guarantors May Consolidate, etc. on Certain Terms. (a) Subject to paragraph (b) of this Section 10.2, no Subsidiary Guarantor may consolidate or merge with or into (whether or not such Subsidiary Guarantor is the surviving entity or Person) another corporation, entity or Person unless (i) the entity or Person formed by or surviving any such consolidation or merger (if other than such Subsidiary Guarantor) assumes all the obligations of such Subsidiary Guarantor pursuant to a supplemental indenture, in a form reasonably satisfactory to the Trustee, under the Securities and this Indenture and (ii) immediately after such transaction, no Default or Event of Default exists. In connection with any consolidation or merger contemplated by this Section 10.2, 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 10.2(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, by way of merger, consolidation or otherwise, or a sale or other disposition of all of the Capital Stock of such Subsidiary Guarantor, then such Subsidiary Guarantor (in the event of a sale or other disposition, by way of such a merger, consolidation or otherwise, of all of the Capital Stock of such Subsidiary Guarantor) or the corporation acquiring the property (in the event of a sale or other disposition of all or substantially all of the assets of such Subsidiary Guarantor) will be released and relieved of any obligations under its Guarantees. 55

63 SECTION 10.3 Addition of Subsidiary Guarantors. (a) If any Subsidiary of the Company guarantees any Funded Indebtedness of the Company at any time subsequent to the Issue Date, then the Company shall (i) cause the Securities to be equally and ratably guaranteed by such Subsidiary, but only to the extent that the Securities are not already guaranteed by such Subsidiary on reasonably comparable terms and (ii) cause such Subsidiary to execute and deliver a supplemental indenture, in a form reasonably satisfactory to the Trustee, evidencing its provision of a guarantee pursuant to the terms hereof. (b) The Company agrees to cause each Subsidiary other than a Foreign 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. (c) Any Person that was not a Subsidiary Guarantor on the Issue Date may become a 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, binding and enforceable 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 10.4 Release of a Subsidiary Guarantor. (a) If, at any time while the Securities remain outstanding, none of the Company's then outstanding Pari Passu Indebtedness (other than the Securities) is guaranteed by a Restricted Subsidiary, such Restricted Subsidiary shall be released and relieved of its obligations under its Guarantee (which shall be terminated and cease to have any force and effect). For purposes of this Section 10.4(a) only, other Pari Passu Indebtedness shall not be deemed to be outstanding if, and as long as, all conditions to defeasance thereof have been satisfied, pursuant to defeasance provisions substantially similar to those set forth in Article Eight hereof. (b) Upon the sale or disposition of a Subsidiary Guarantor (or substantially all of its assets), which is otherwise in compliance with the terms of this Indenture, including but not limited to the provisions of Section 10.2, or if a Subsidiary ceases to be a Restricted Subsidiary, such Subsidiary shall be released and relieved of its obligations under its Guarantee (which shall terminate and cease to have any force and effect). The Trustee shall deliver an appropriate instrument evidencing such release upon receipt of a request by the Company accompanied by an Officers' Certificate and an Opinion of Counsel certifying that such sale or other disposition or cessation was made by the Company in accordance with the provisions of this Indenture. 56

64 (c) Any Subsidiary Guarantor not so released pursuant to this Article Ten remains liable for the full amount of principal of and interest on the Securities as provided in this Article Ten. SECTION 10.5 Limitation of Subsidiary Guarantor's Liability. Each Subsidiary Guarantor, and by its acceptance hereof each Holder, hereby confirms that it is the intention of all such parties that the guarantee by such Subsidiary Guarantor pursuant to its Guarantee not constitute a fraudulent transfer or conveyance for purposes of any federal or state law. To effectuate the foregoing intention, the Holders and each Subsidiary Guarantor hereby irrevocably agree that the obligations of each Subsidiary Guarantor under the Guarantee shall be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Subsidiary Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Subsidiary Guarantor in respect of the obligations of such other Subsidiary Guarantor under its Guarantee or pursuant to Section 10.6, result in the obligations of such Subsidiary Guarantor under the Guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal or state law. This Section 10.5 is for the benefit of the creditors of each Subsidiary Guarantor, and, for purposes of applicable fraudulent transfer and fraudulent conveyance law, any Indebtedness of a Subsidiary Guarantor pursuant to a bank credit facility shall be deemed to have been incurred prior to the incurrence by such Subsidiary Guarantor of its liability under the Guarantee. SECTION 10.6 Contribution. In order to provide for just and equitable contribution among the Subsidiary Guarantors, the Subsidiary Guarantors agree, inter se, that in the event any payment or distribution is made by any Subsidiary Guarantor (a "Funding Guarantor") under the Guarantee, such Funding Guarantor shall be entitled to a contribution from each other Subsidiary Guarantor in a pro rata amount based on the Adjusted Net Assets of each Subsidiary Guarantor (including the Funding Guarantor) for all payments, damages and expenses incurred by the Funding Guarantor in discharging the Company's obligations with respect to the Securities or any other Subsidiary Guarantor's obligations with respect to the Guarantee. SECTION 10.7 Execution and Delivery of Guarantee. To further evidence the Guarantees set forth in Section 10.1, each Subsidiary Guarantor hereby agrees that a notation relating to such Guarantee, in substantially the form of Exhibit A-1, shall be endorsed on each Security authenticated and delivered by the Trustee and executed by either manual or facsimile signature of one Officer of each Subsidiary Guarantor. Each of the Subsidiary Guarantors hereby agrees that its Guarantee set forth in Section 10.1 shall remain in full force and effect notwithstanding any failure to endorse on each Security a notation relating to such Guarantee. 57

65 If an Officer of a Subsidiary Guarantor whose signature is on this Indenture or a Security no longer holds that office at the time the Trustee authenticates such Security or at any time thereafter, such Subsidiary Guarantor's Guarantee of such Security shall be valid nevertheless. The delivery of any Security by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of any Guarantee set forth in this Indenture on behalf of the Subsidiary Guarantor. SECTION 10.8 Severability. In case any provision of this Guarantee shall be invalid, illegal or unenforceable, that portion of such provision that is not invalid, illegal or unenforceable shall remain in effect, and the validity, legality, and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

INC. J.P. MORGAN SECURITIES INC. LEHMAN BROTHERS INC. c/o Donaldson, Lufkin & Jenrette Securities Corporation 277 Park Avenue New York, New York 10172 Ladies and Gentlemen: Chesapeake Energy Corporation, an Oklahoma corporation (the "Company"), and its subsidiaries listed on the signature pages hereto (the "Subsidiary Guarantors") propose to issue and sell to you (the "Initial Purchasers"), upon the terms set forth in a purchase agreement of even date herewith (the "Purchase Agreement"), $150,000,000 principal amount of the Company's 7 7/8% Senior Notes due 2004 (the "2004 Senior Notes") and $150,000,000 principal amount of the Company's 8 1/2% Senior Notes due 2012 (the "2012 Senior Notes" and, collectively with the 2004 Senior Notes, the "Senior Notes"). The 2004 Senior Notes and the 2012 Senior Notes will be issued pursuant to separate indentures, each to be dated as of March 15, 1997 (respectively, the "2004 Senior Notes Indenture" and the "2012 Senior Notes Indenture" and, collectively, the "Indentures") by and among the Company, the Subsidiary Guarantors and United States Trust Company of New York, as trustee (with respect to each of the Indentures, the "Trustee"), substantially in the forms previously furnished to you. Capitalized terms used but not specifically defined herein are defined in the Purchase Agreement and used herein as so defined. References to each issue of Senior Notes shall include the related Guarantees (as defined in the related Indenture) of the Subsidiary Guarantors. As used herein, "Registrable Senior Notes" shall mean each Senior Note of each issue, until the earliest to occur of (a) the date on which such Senior Note is exchanged in the applicable Registered Exchange Offer for an Exchange Note (each as defined below) of such issue and entitled to be resold to the

2 public by the holder thereof without complying with the prospectus delivery requirements of the Securities Act of 1933, as amended (the "Securities Act"), (b) the date on which such Senior Note has been effectively registered under the Securities Act and disposed of pursuant to a Senior Notes Shelf Registration (as defined below) and (c) the date on which such Senior Note is distributed to the public pursuant to Rule 144 under the Securities Act or by a Broker-Dealer (as defined below) pursuant to the "Plan of Distribution" contemplated by the registration statement relating to the Registered Exchange Offer (including delivery of the prospectus contained therein). In consideration of the premises, and the mutual covenants, representations, warranties and agreements herein contained, the parties hereby agree as follows: 1. Registered Exchange Offers. (a) Promptly (and in any event not more than 60 days) following the closing date of the sale of the Senior Notes (the "Closing Date"), the Company and the Subsidiary Guarantors shall file with the Commission, with respect to each of the 2004 Senior Notes and the 2012 Senior Notes, a registration statement on an appropriate form under the Securities Act with respect to proposed offers (the "Registered Exchange Offers") to the holders of the Registrable Senior Notes of the applicable issue to issue and deliver to such holders, in exchange for the Registrable Senior Notes of such issue, a like principal amount of debt securities of the Company identical in all material respects to the Registrable Senior Notes of such issue (the "Exchange Notes"), shall use their best efforts to cause such registration statement to become effective under the Securities Act no later than 160 days after the Closing Date and, upon the effectiveness of such registration statement, shall commence each Registered Exchange Offer and shall cause the same to remain open for such period of time to be determined by the Company (but not less than 30 nor more than 60 days after the commencement of the applicable Registered Exchange Offer), and to be conducted in accordance with such procedures, as may be required by the applicable provisions of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), it being the objective of such Registered Exchange Offers to enable each holder of Registrable Senior Notes of the applicable issue electing to exchange Registrable Senior Notes of such issue for Exchange Notes of such issue (assuming that such holder is not an affiliate of the Company within the meaning of the Securities Act, acquires the Exchange Notes in the ordinary course of such holder's business and has no arrangements with any person to participate in the distribution of the Exchange Notes) to trade such Exchange Notes from and after their receipt without any limitations or restrictions under the Securities Act, subject as to a Broker-Dealer to the provisions of Section 1(b) hereof, or the Exchange Act and without material restrictions under the securities laws of a substantial proportion of the several states of the United States. (b) The Company shall indicate in a "Plan of Distribution" section contained in the final prospectus constituting a part of the registration statement relating to the Registered Exchange Offers that any broker or dealer registered under the Exchange Act (each a "Broker-Dealer") who holds Registrable Senior Notes that were acquired for its own account as a result of market-making activities or other trading activities (other than Registrable Senior Notes acquired -2-

3 directly from the Company), may exchange such Registrable Senior Notes for Exchange Notes of the applicable issue pursuant to the applicable Registered Exchange Offer; however, such Broker-Dealer may be deemed an "underwriter" within the meaning of the Securities Act and, therefore, must deliver a prospectus meeting the requirements of the Securities Act in connection with any resales of such Exchange Notes received by it in the applicable Registered Exchange Offer, which prospectus delivery requirement may be satisfied by the delivery by such Broker-Dealer of the final prospectus contained in the registration statement relating to such Registered Exchange Offer. Such "Plan of Distribution" section also shall state that the delivery by a Broker-Dealer of the final prospectus relating to the Registered Exchange Offer in connection with resales of Exchange Notes shall not be deemed to be an admission by such Broker-Dealer that it is an "underwriter" within the meaning of the Securities Act, and shall contain all other information with respect to resales of the Exchange Notes by Broker-Dealers that the Commission may require in connection therewith, but such "Plan of Distribution" shall not name any such Broker-Dealer or disclose the amount of Exchange Notes held by any such Broker- Dealer except to the extent required by the Commission as a result of a change in policy after the date of this Agreement. (c) In connection with such Registered Exchange Offers and the offer and sale of Exchange Notes by Broker-Dealers as contemplated above, the Company and the Subsidiary Guarantors shall take such other and further action, including making appropriate filings under state securities laws and delivering such number of final prospectuses relating to the Registered Exchange Offers as any Broker-Dealer proposing to deliver the same in connection with its resales of Exchange Notes may reasonably request, as may be necessary to realize the foregoing objectives. The Company and the Subsidiary Guarantors shall cause the registration statement relating to the Registered Exchange Offers to remain continuously effective for a period of one year, if required, from the date on which such registration statement is first declared effective, and shall supplement or amend the prospectus contained therein to the extent necessary to permit such prospectus (as supplemented or amended) to be delivered by Broker-Dealers in connection with their resales of Exchange Notes as aforesaid. 2. Senior Notes Shelf Registration. If, because of any change in currently prevailing interpretations of the Commission's staff, the Company is not permitted to effect a Registered Exchange Offer, as contemplated by Section 1 hereof, the following provisions shall apply with respect to each issue of Senior Notes: (a) Promptly (and in any event not more than 60 days) following the date of closing (the "Closing Date") of the sale of the Senior Notes, the Company and the Subsidiary Guarantors shall file with the Commission, and thereafter use their best efforts to have declared effective not later than 160 days after the Closing Date, a registration statement on an appropriate form under the Securities Act relating to the offer and sale of the Registrable Senior Notes by the holders thereof, from time to time in accordance with the methods of distribution set forth in such registration statement and Rule 415 under the Securities Act (the "Senior Notes Shelf Registration"). -3-

4 (b) The Company and the Subsidiary Guarantors agree to use their best efforts to keep the registration statement relating to the Senior Notes Shelf Registration continuously effective in order to permit the prospectus included therein to be usable by the holders of the Registrable Senior Notes for a period of three years from the Closing Date or such shorter period (i) as may be set forth in any amendment to Rule 144(k) of the Securities Act of 1933, or any amendment thereto, when such amendment becomes effective, or (ii) that will terminate when all the Registrable Senior Notes covered by the registration statement have been sold pursuant to such registration statement; provided, that the Company and the Subsidiary Guarantors shall be deemed not to have used their best efforts to keep the registration statement effective during the requisite period if they voluntarily take any action that would result in holders of the Registrable Senior Notes covered thereby not being able to offer and sell such Registrable Senior Notes during that period, unless such action is required by applicable law, and provided, further, that the foregoing shall not apply if the Company determines, in its reasonable judgment, upon advice of counsel, as authorized by a resolution of its Board of Directors, that the continued effectiveness and usability of such registration statement would (i) require the disclosure of material information, which the Company has a bona fide business reason for preserving as confidential, or (ii) interfere with any financing, acquisition, corporate reorganization or other material transaction involving the Company or any of its Affiliates (as defined in the rules and regulations adopted under the Exchange Act); provided, however, that the failure to keep the registration statement effective and usable for offers and sales of Registrable Senior Notes for such reasons shall last no longer than 60 days in any 12-month period (whereafter Senior Notes Liquidated Damages (as defined in Section 6) shall accrue and be payable), so long as the Company promptly thereafter complies with the requirements of Section 3(h) hereof, if applicable. Any such period during which the Company and the Subsidiary Guarantors fail to keep the registration statement effective and usable for offers and sales of Registrable Senior Notes is referred to as a "Suspension Period." A Suspension Period shall commence on and include the date that the Company gives notice that the registration statement is no longer effective or the prospectus included therein is no longer usable for offers and sales of Registrable Senior Notes and shall end on the date when each seller of Registrable Senior Notes covered by such registration statement either receives the copies of the supplemented or amended prospectus contemplated by Section 3(h) hereof or is advised in writing by the Company that use of the prospectus may be resumed. (c) Notwithstanding any other provisions of this Agreement to the contrary, the Company and the Subsidiary Guarantors will cause the Senior Notes Shelf Registration and the related prospectus and any amendment or supplement thereto, as of the effective date of such registration statement, amendment or supplement, (i) to comply in all material respects with the applicable requirements of the Securities Act and the rules and regulations of the Commission and (ii) not to contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. 3. Registration Procedures. In connection with, to the extent applicable, any Registered Exchange Offer pursuant to Section 1 hereof, or any Senior Notes Shelf Registration -4-

5 pursuant to Section 2 hereof, the following provisions shall apply with respect to each issue of Senior Notes: (a) If requested by any holder of Registrable Senior Notes or the managing underwriter, if any, with respect to the Senior Notes Shelf Registration, the Company shall furnish to each such holder of Registrable Senior Notes or such managing underwriter, prior to the filing thereof with the Commission, a copy of the applicable registration statement and each amendment thereof and each supplement, if any, to the prospectus included therein. The Company shall use its best efforts to reflect in each such document, when so filed with the Commission, such comments as such holder or managing underwriter reasonably may propose. (b) The Company shall advise the holders of Registrable Senior Notes or the Exchange Notes, and the managing underwriter, if any, and, if requested by any such person, confirm such advice in writing: (i) when the applicable registration statement and any amendment thereto has been filed with the Commission and when the registration statement or any post-effective amendment thereto has become effective; (ii) of the issuance by the Commission of any stop order suspending the effectiveness of the applicable registration statement or the initiation of any proceedings for that purpose; (iii) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Registrable Senior Notes or the Exchange Notes for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and (iv) of the happening of any event that requires the making of any changes in the registration statement or the prospectus in order to make the statements therein not misleading (which advice shall be accompanied by an instruction to suspend the use of the prospectus until the requisite changes have been made). (c) The Company will make every reasonable effort to obtain the withdrawal of any order suspending the effectiveness of the registration statement at the earliest possible time. (d) The Company will furnish to each holder of the Registrable Senior Notes or the Exchange Notes included within the coverage of the Registered Exchange Offer or the Senior Notes Shelf Registration, as appropriate, without charge, at least one copy of the registration statement in the form in which it was declared effective by the Commission and any post-effective amendment thereto, including financial statements and schedules, and, if the holder so requests in writing, all exhibits (including those incorporated by reference). -5-

6 (e) The Company will deliver to each holder of the Registrable Senior Notes or the Exchange Notes included within the coverage of the Registered Exchange Offer or the Senior Notes Shelf Registration, as appropriate, without charge, as many copies of the prospectus (including each preliminary prospectus) included in the registration statement and any amendment or supplement thereto as such persons may reasonably request; the Company consents to the use of the prospectus or any amendment or supplement thereto by each of the selling holders of the Registrable Senior Notes or the Exchange Notes in connection with the offering and sale of the Registrable Senior Notes or the Exchange Notes covered by the prospectus or any amendment or supplement thereto. (f) Prior to any public offering of the Registrable Senior Notes or the Exchange Notes pursuant to the Registered Exchange Offer or the Senior Notes Shelf Registration, as the case may be, the Company will register or qualify, or cooperate with the holders of the Registrable Senior Notes or the Exchange Notes covered thereby and their respective counsel in connection with the registration or qualification of, such Registrable Senior Notes or Exchange Notes for offer and sale under the securities or blue sky laws of such jurisdictions as any seller reasonably requests in writing and do any and all other acts or things necessary or advisable to enable the offer and sale in such jurisdictions, of the Registrable Senior Notes or the Exchange Notes covered by the Registered Exchange Offer or the Senior Notes Shelf Registration, as the case may be; provided, that the Company will not be required to qualify generally to do business in any jurisdiction where it is not then so qualified or to take any action which would subject it to general service of process or to taxation in any such jurisdiction where it is not then so subject. (g) The Company will cooperate with the holders of the Registrable Senior Notes and the Exchange Notes to facilitate the timely preparation and delivery of certificates representing the Registrable Senior Notes and the Exchange Notes to be sold in the Registered Exchange Offer or the Senior Notes Shelf Registration, as the case may be, free of any restrictive legends and in such denominations and registered in such names as the holders may request prior to sales of the Registrable Senior Notes or the Exchange Notes, pursuant to the Registered Exchange Offer or the Senior Notes Shelf Registration, as the case may be. (h) Upon the occurrence of any event contemplated by paragraph (b)(v) above, the Company will prepare a post-effective amendment to the registration statement or a supplement to the related prospectus or file any other required document so that, as thereafter delivered to purchasers of the Registrable Senior Notes or the Exchange Notes, the prospectus will not contain an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein not misleading. (i) Not later than the effective date of the applicable registration statement, the Company will provide a CUSIP number for the Registrable Senior Notes or the Exchange Notes, as the case may be, and provide the Trustee with printed certificates for the Registrable Senior Notes or the Exchange Notes, as the case may be, in a form eligible for deposit with The Depository Trust Company. -6-

7 (j) The Company will use its best efforts to comply with all applicable rules and regulations of the Commission and will make generally available to its security holders an earnings statement satisfying the provisions of Section 11(a) of the Securities Act, no later than 60 days after the end of 12-month period (or 90 days, if such period is a fiscal year) beginning with the first month of the Company's first fiscal quarter commencing after the effective date of each of the Registered Exchange Offer and the Senior Notes Shelf Registration, which statements shall cover such 12-month period. (k) The Company will cause the Indenture to be qualified under the Trust Indenture Act of 1939 upon effectiveness of the registration statement contemplated by Section 1(a) or Section 2(a). (l) The Company may require each holder of Registrable Senior Notes to be sold pursuant to the Senior Notes Shelf Registration, to furnish to the Company such information regarding the holder and the distribution of such Registrable Senior Notes as the Company may from time to time reasonably require for inclusion in the registration statement. 4. Registration Expenses. The Company and the Subsidiary Guarantors will bear all expenses incurred in connection with the performance of their obligations under Sections 1 through 3 hereof and will bear or reimburse the holders of the Registrable Senior Notes for the reasonable fees and disbursements of one firm of counsel designated by the holders of a majority in principal amount of the Registrable Senior Notes to act as counsel for the holders of the Registrable Senior Notes in connection therewith. 5. Indemnification. (a) Indemnification by Company and the Subsidiary Guarantors. The Company and the Subsidiary Guarantors, jointly and severally, shall indemnify and hold harmless (i) each Initial Purchaser, (ii) in the case of any Senior Notes Shelf Registration, each holder of Registrable Senior Notes, and (iii) in the case of any Registered Exchange Offer, each Broker-Dealer who holds Exchange Notes acquired for its own account pursuant to the Exchange Offer, and, in any such case, each Initial Purchaser's and such holder's officers, directors, employees and agents and each person who controls each such Initial Purchaser, now or hereafter, and each such holder within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act (each such person being sometimes hereinafter referred to as an "Indemnified Person") from and against any and all losses, claims, damages, liabilities and judgments caused by any untrue statement or alleged untrue statement of a material fact contained in any registration statement or prospectus or in any amendment or supplement thereto relating to the Senior Notes Shelf Registration or the Registered Exchange Offer, as the case may be, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, except insofar as such losses, claims, damages, liabilities or judgments are caused by any such untrue statement or omission or allegation thereof based upon information relating to such Indemnified Person furnished in writing -7-

8 to the Company by such Indemnified Person expressly for use therein. The indemnity will be in addition to any liability which the Company and the Subsidiary Guarantors may otherwise have. If any action or proceeding (including any governmental investigation or inquiry) shall be brought or asserted against an Indemnified Person in respect of which indemnity may be sought from the Company or the Subsidiary Guarantors, such Indemnified Person shall promptly notify the Company and the Subsidiary Guarantors in writing, and the Company and the Subsidiary Guarantors shall assume the defense thereof, including the employment of counsel reasonably satisfactory to such Indemnified Person and the payment of all reasonable expenses. Such Indemnified Person shall have the right to employ separate counsel in any such action and to participate in the defense thereof, but the fees and expenses of such counsel shall be the expense of such Indemnified Person unless (a) the Company and the Subsidiary Guarantors have agreed to pay such fees and expenses or (b) the Company and the Subsidiary Guarantors shall have failed to assume the defense of such action or proceeding and to employ counsel reasonably satisfactory to such Indemnified Person in any such action or proceeding within a reasonable time after notice of commencement of such action or proceeding or (c) the named parties to any such action or proceeding (including any impleaded parties) include such Indemnified Person and the Company and/or the Subsidiary Guarantors, and such Indemnified Person shall have been advised in writing by counsel that there may be one or more legal defenses available to such Indemnified Person which are different from or additional to those available to the Company and/or the Subsidiary Guarantors (in which case, if such Indemnified Person notifies the Company and the Subsidiary Guarantors in writing that it elects to employ separate counsel at the expense of the Company and the Subsidiary Guarantors, the Company and the Subsidiary Guarantors shall not have the right to assume the defense of such action or proceeding on behalf of such Indemnified Person, it being understood, however, that the Company and the Subsidiary Guarantors shall not, in connection with any one such action or separate but substantially similar or related actions or proceedings in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate firm of attorneys (in addition to local counsel) at any time for such Indemnified Person and any other Indemnified Persons, which firm shall be designated in writing by such Indemnified Persons (which shall be reasonably satisfactory to the Company and the Subsidiary Guarantors), and that all such fees and expenses shall be reimbursed as they are billed). The Company and the Subsidiary Guarantors shall not be liable for any settlement of any such action or proceeding effected without their written consent (not to be unreasonably withheld), but if settled with their written consent, or if there be a final, unappealable judgment for the plaintiff in any such action or proceeding, the Company and the Subsidiary Guarantors agree to indemnify and hold harmless such Indemnified Persons from and against any loss or liability by reason of such settlement or judgment. The Company and the Subsidiary Guarantors shall not, without the prior written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is a party and indemnity has been sought hereunder by such Indemnified Person; provided however, that the Company and the Subsidiary Guarantors may effect such a settlement without the consent of such Indemnified Person if such settlement includes an unconditional release of such Indemnified Person from all lability for claims that are the subject matter of such proceeding or the Company and the Subsidiary Guarantors -8-

9 indemnify such Indemnified Person in writing and post a bond for an amount equal to the maximum liability for all such claims as contemplated above. (b) Indemnification by Holders. In the event of a Senior Notes Shelf Registration, each holder of Registrable Senior Notes agrees to indemnify and hold harmless the Company and the Subsidiary Guarantors, their directors and officers, employees and agents and each person, if any, controlling the Company and the Subsidiary Guarantors within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company to such holder, but only with respect to information relating to such holder or the distribution furnished in writing by such holder expressly for use in any registration statement or prospectus or any amendment or supplement thereto or any preliminary prospectus relating to the Senior Notes Shelf Registration, provided, however, that no such holder shall be liable for any indemnity claims hereunder in excess of the amount of net proceeds received by such holder from the sale of Registrable Senior Notes pursuant to the Senior Notes Shelf Registration. If any action or proceeding shall be brought against the Company, the Subsidiary Guarantors or their directors, officers, employees or agents or any such controlling person, in respect of which indemnity may be sought against a holder of Registrable Senior Notes, such holder shall have the rights and duties given the Company and the Subsidiary Guarantors and the Company and the Subsidiary Guarantors or their directors, officers, employees or agents or such controlling person shall have the rights and duties given to each holder by Section 5(a) hereof. The Company and the Subsidiary Guarantors shall be entitled to receive indemnities from underwriters, selling brokers, dealer managers and similar securities industry professionals participating in the distribution, to the same extent as provided above with respect to information so furnished in writing by such persons specifically for inclusion in any prospectus or registration statement or any amendment or supplement thereto. (c) Contribution. If the indemnification provided for in this Section 5 is unavailable to an indemnified party under Section 5(a) or Section 5(b) hereof (other than by reason of exceptions provided in those Sections) in respect of any losses, claims, damages, liabilities or judgments referred to therein, then each applicable indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities or judgments in such proportion as is appropriate to reflect not only the relative benefits but also the relative fault of the Company and the Subsidiary Guarantors on the one hand and of the Indemnified Person on the other in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or judgments, as well as any other relevant equitable considerations. The relative fault of the Company and the Subsidiary Guarantors on the one hand and of the Indemnified Person on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company and the Subsidiary Guarantors or by the Indemnified Person and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the -9-

10 limitations set forth in the second paragraph of Section 5(a), any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim. The Company, the Subsidiary Guarantors and the holders of the Registrable Senior Notes and Exchange Notes agree that it would not be just and equitable if contribution pursuant to this Section 5(c) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. 6. Additional Interest Under Certain Circumstances; Remedies. If the Company and the Subsidiary Guarantors fail to file within 60 days, or cause to become effective within 160 days, the registration statement relating to the Registered Exchange Offers or the Senior Notes Shelf Registration, as applicable, or (subject to Section 2(b)) the Senior Notes Shelf Registration is declared effective but thereafter ceases to be effective in connection with resales of the Registrable Senior Notes (each such event, a "Registration Default"), then the Company agrees to pay to each holder of Registrable Senior Notes of the applicable issue, accruing from the date of the first such Registration Default, liquidated damages in an amount equal to one-half of one percent (0.5%) per annum of the principal amount of Registrable Senior Notes held by such holder during the first 160-day period immediately following the occurrence of the first such Registration Default, increasing by an additional one-half of one percent (0.5%) per annum of the principal amount of such Registrable Senior Notes during each subsequent 160-day period, up to a maximum amount of liquidated damages equal to two percent (2.0%) per annum of the principal amount of such Registrable Senior Notes ("Senior Notes Liquidated Damages"), and ceasing to accrue on the date such Registration Default has been cured by, as applicable, the filing, declaration of effectiveness or withdrawal of suspension of effectiveness of the applicable registration statement. The Company shall notify the Trustee within one business day after (i) each and every Registration Default and (ii) the date the Registration Default has been so cured.

The Old Notes due 2004 were, and the New Notes due 2004 will be, issued pursuant to the Indenture dated as of March 15, 1997 among the Company, as issuer, the Subsidiary Guarantors, as guarantors, and United States Trust Company of New York ("U.S. Trust"), as trustee (the "Notes due 2004 Indenture"), which will be filed as Exhibit 4.1 to the Registration Statement. The Old Notes due 2012 were, and the New Notes due 2012 will be, issued pursuant to the Indenture dated as of March 15, 1997 among the Company, as issuer, the Subsidiary Guarantors, as guarantors, and U.S. Trust, as trustee (the "Notes due 2012 Indenture"), which will be filed as Exhibit 4.3 to the Registration Statement. The New Notes due 2004 and the New Notes due 2012 are referred to, collectively, as the "New Notes," and the Notes due 2004 Indenture and the Notes due 2012 Indenture are referred to, together, as the "Indentures." We have examined the Indentures, the forms of certificate which will evidence the New Notes (the "Certificates"), and certain corporate records of the Company, and we have made such other

2 -2- investigations as we have deemed appropriate in order to express the opinion set forth herein. Based upon the foregoing, we are of the opinion that: 1. The Company is a corporation duly organized and validly existing under the laws of the State of Oklahoma; and 2. The Indentures, the New Notes, and the guarantees of the New Notes by the Subsidiary Guarantors (the "Guarantees") have been duly and validly authorized, and the New Notes and Guarantees, when issued in accordance with the terms of the respective Indentures, will constitute binding obligations of the Company and the Subsidiary Guarantors, enforceable against the Company and the Subsidiary Guarantors in accordance with the terms of the Indentures and the Certificates, subject to (a) applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and similar laws relating to creditors' rights and remedies generally and (b) general principles of equity (whether enforcement is sought in a proceeding at law or in equity). While each of the Indentures provides that it will be governed by the substantive laws of the State of New York, we have assumed, for purposes of our opinion, that the Indentures will be governed by the laws of the State of Oklahoma. We hereby consent to the inclusion of this opinion as an exhibit to the Registration Statement and to the reference to our firm under the caption "Legal Matters" in the Prospectus which is a part of the Registration Statement.

Subject to, and effective upon, the acceptance for exchange of the Old Notes tendered herewith, the undersigned hereby exchanges, assigns and transfers to, or upon the order of, Chesapeake all right, title and interest in and to such Old Notes. The undersigned hereby irrevocably constitutes and appoints the Exchange Agent as the true and lawful agent and attorney-in-fact of the undersigned (with full knowledge that said Exchange Agent acts as the agent of the undersigned in connection with the Exchange Offer) to cause the Old Notes to be assigned, transferred and exchanged. The undersigned represents and warrants that it has full power and authority to tender, exchange, assign and transfer the Old Notes and to acquire New Notes issuable upon the exchange of such tendered Old Notes, and that, when the same are accepted for exchange, Chesapeake will acquire good and unencumbered title to the tendered Old Notes, free and clear of all liens, restrictions, charges and encumbrances and not subject to any adverse claim. The undersigned also warrants that it will, upon request, execute and deliver any additional documents deemed by Chesapeake to be necessary or desirable to complete the exchange, assignment and transfer of tendered Old Notes or to transfer ownership of such Old Notes on the account books maintained by The Depository Trust Company. The Exchange Offer is subject to certain conditions as set forth in the Prospectus under the caption "The Exchange Offer -- Conditions of the Exchange Offer." The undersigned recognizes that as a result of these conditions (which may be waived, in whole or in part, by Chesapeake) as more particularly set forth in the Prospectus, Chesapeake may not be required to exchange any of the Old Notes tendered hereby and, in such event, the Old Notes not exchanged will be returned to the undersigned at the address shown below the signature of the undersigned. By tendering, each Holder of Old Notes represents to Chesapeake that (i) the New Notes acquired pursuant to the Exchange Offer are being obtained in the ordinary course of business of the person receiving such New Notes, whether or not such person is such Holder, (ii) neither the Holder of Old Notes nor any such other person has an arrangement or understanding with any person to participate in the distribution of such New Notes, (iii) if the Holder is not a broker- dealer or is a broker-dealer but will not receive New Notes for its own account in exchange for Old Notes, neither the Holder nor any such other person is engaged in or intends to participate in a distribution of the New Notes and (iv) neither the Holder nor any such other person is an "affiliate" of Chesapeake within the meaning of Rule 405 under the Securities Act of 1933, as amended (the "Securities Act") or, if such Holder is an "affiliate," that such Holder will comply with the registration and prospectus delivery requirements of the Securities Act to the extent applicable. If the tendering Holder is a broker-dealer (whether or not it is also an "affiliate" of Chesapeake within the meaning of Rule 405 under the Securities Act) that will receive New Notes for its own account in exchange for Old Notes, it acknowledges that it will deliver a prospectus meeting the requirements of the Securities Act in connection with any resale of such New Notes. By acknowledging that it will deliver and by delivering a prospectus meeting the requirements of the Securities Act in connection with any resale of such New Notes, the undersigned is not deemed to admit that it is an "underwriter" within the meaning of the Securities Act. All authority herein conferred or agreed to be conferred shall survive the death, bankruptcy or incapacity of the undersigned and every obligation of the undersigned hereunder shall be binding upon -4-

7 INSTRUCTIONS FORMING PART OF THE TERMS AND CONDITIONS OF THE EXCHANGE OFFER 1. DELIVERY OF THIS LETTER OF TRANSMITTAL AND CERTIFICATES. Certificates for all physically delivered Old Notes, as well as a properly completed and duly executed copy of this Letter of Transmittal or facsimile thereof, and any other documents required by this Letter of Transmittal, must be received by the Exchange Agent at any of its addresses set forth herein on or prior to the Expiration Date. THE METHOD OF DELIVERY OF OLD NOTES, THIS LETTER OF TRANSMITTAL AND ALL OTHER REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND RISK OF THE HOLDER AND, EXCEPT AS OTHERWISE PROVIDED BELOW, THE DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE EXCHANGE AGENT. INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT HOLDERS USE AN OVERNIGHT OR HAND DELIVERY SERVICE. Holders whose Old Notes are not immediately available or who cannot deliver their Old Notes and all other required documents to the Exchange Agent on or prior to the Expiration Date may tender their Old Notes pursuant to the guaranteed delivery procedure set forth in the Prospectus under "The Exchange Offer -- Terms of the Exchange Offer -- Guaranteed Delivery Procedures." Pursuant to such procedure: (i) such tender must be made by or through an Eligible Institution (as defined in the Prospectus); (ii) on or prior to the Expiration Date, the Exchange Agent must have received from such Eligible Institution a letter, telegram or facsimile transmission setting forth the name and address of the tendering Holder, the name(s) in which such Old Notes are registered, and the certificate number(s) of the Old Notes to be tendered; and (iii) all tendered Old Notes as well as this Letter of Transmittal and all other documents required by this Letter of Transmittal must be received by the Exchange Agent within three New York Stock Exchange trading days after the date of execution of such letter, telex, telegram or facsimile transmission, all as provided in the Prospectus under the caption "The Exchange Offer -- Terms of the Exchange Offer -- Guaranteed Delivery Procedures." No alternative, conditional, irregular or contingent tenders will be accepted. All tendering Holders, by execution of this Letter of Transmittal (or facsimile thereof), shall waive any right to receive notice of the acceptance of the Old Notes for exchange. 2. PARTIAL TENDERS; WITHDRAWALS. Tenders of Old Notes will be accepted in denominations of $1,000 and integral multiples in excess thereof. If less than the entire principal amount of Old Notes evidenced by a submitted certificate is tendered, the tendering Holder must fill in the principal amount tendered in the column entitled "Principal Amount Tendered." A newly issued certificate for the principal amount of Old Notes submitted but not tendered will be sent to such Holder as soon as practicable after the Expiration Date. All Old Notes delivered to the Exchange Agent will be deemed to have been tendered unless otherwise indicated. To withdraw a tender of Old Notes in the Exchange Offer, a written or facsimile transmission notice of withdrawal must be received by the Exchange Agent at its address set forth herein prior to 5:00 p.m., New York City time, on the Expiration Date. Any such notice of withdrawal must (i) specify the name of the person having deposited the Old Notes to be withdrawn (the "Depositor"), (ii) identify the Old Notes to be withdrawn (including the certificate number or numbers and principal amount of such Old Notes), (iii) contain a statement that such holder is withdrawing its election to have such Old Notes exchanged, (iv) be signed by the Holder in the same manner as the original signature on the Letter of Transmittal by which such Old Notes were tendered (including any required signature -7-

8 guarantees) or be accompanied by documents of transfer sufficient to have the Trustee with respect to the Old Notes register the transfer of such Old Notes in the name of the person withdrawing the tender and (v) specify the name in which any such Old Notes are to be registered, if different from that of the Depositor. If Old Notes have been tendered pursuant to the procedure for book-entry transfer, any notice of withdrawal must specify the name and number of the account at the book-entry transfer facility. All questions as to the validity, form and eligibility (including time of receipt) of such notices will be determined by Chesapeake, whose determination shall be final and binding on all parties. Any Old Notes so withdrawn will be deemed not to have been validly tendered for purposes of the Exchange Offer and no New Notes will be issued with respect thereto unless the Old Notes so withdrawn are validly retendered. Any Old Notes which have been tendered but which are not accepted for exchange will be returned to the Holder thereof without cost to such Holder as soon as practicable after withdrawal, rejection of tender or termination of the Exchange Offer. Properly withdrawn Old Notes may be retendered by following one of the procedures described herein at any time prior to the business day prior to the Expiration Date. 3. SIGNATURE ON THIS LETTER OF TRANSMITTAL; WRITTEN INSTRUMENTS AND ENDORSEMENTS; GUARANTEE OF SIGNATURES. If this Letter of Transmittal is signed by the registered Holder(s) of the Old Notes tendered hereby, the signature must correspond with the name(s) as written on the face of certificates without alteration, enlargement or any change whatsoever. If tendered Old Notes are registered in the name of the signer of the Letter of Transmittal and the New Notes to be issued in exchange therefor are to be issued (and any untendered Old Notes are to be reissued) in the name of the registered holder (including any participant in The Depository Trust Company (also referred to as a book-entry facility) whose name appears on a security listing as the owner of Old Notes), the signature of such signer need not be guaranteed.

TRANSFER TAXES. Chesapeake shall pay all transfer taxes, if any, applicable to the exchange of Old Notes pursuant to the Exchange Offer. If, however, certificates representing New Notes, or Old Notes for principal amounts not tendered or accepted for exchange, are to be delivered to, or are to be issued in the name of, any person other than the registered Holder of the Old Notes tendered hereby, or if a transfer tax is imposed for any reason other than the exchange of Old Notes pursuant to the Exchange Offer, then the amount of any such transfer taxes (whether imposed on the registered Holder or any other person) will be payable by the tendering Holder. If satisfactory evidence of payment of such taxes or exemption therefrom is not submitted herewith, the amount of such transfer taxes will be billed directly to such tendering Holder. Except as provided in this Instruction 4, it will not be necessary for transfer tax stamps to be affixed to the Old Notes listed in this Letter of Transmittal. 5. WAIVER OF CONDITIONS.

Chesapeake reserves the absolute right to reject any or all Letters of Transmittal or tenders that are not in proper form or the acceptance of which would, in the opinion of Chesapeake's counsel, be unlawful. Chesapeake also reserves the right to waive any irregularities or conditions of tender as to the particular Old Notes covered by any Letter of Transmittal or tendered pursuant to such Letter of Transmittal.
