1. Basis of Presentation and Summary of Significant Accounting Policies

Principles of Consolidation

The accompanying unaudited condensed consolidated financial statements of Chesapeake Energy Corporation and its subsidiaries have been prepared in accordance with the instructions to Form 10-Q as prescribed by the Securities and Exchange Commission. Chesapeake’s 2004 Annual Report on Form 10-K includes certain definitions and a summary of significant accounting policies and should be read in conjunction with this Form 10-Q. 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 and six months ended June 30, 2005 are not necessarily indicative of the results to be expected for the full year. This Form 10-Q relates to the three and six months ended June 30, 2005 (the “Current Quarter” and “Current Period”, respectively) and the three and six months ended June 30, 2004 (the “Prior Quarter” and “Prior Period”, respectively).

Stock-Based Compensation

Stock Options. Chesapeake has elected to follow APB No. 25, Accounting for Stock Issued to Employees, and related interpretations in accounting for its employee and director stock options. Under APB No. 25, compensation expense is recognized for the difference between the option exercise price and market value on the measurement date. The original issuance of stock options has not resulted in the recognition of compensation expense because the exercise price of the stock options granted under the plans has equaled the market price of the underlying stock on the date of grant. In March 2000, the Financial Accounting Standards Board issued FASB Interpretation No. 44 (FIN 44), which provided clarification regarding the application of APB No. 25. FIN 44 specifically addressed the accounting consequence of various modifications to the terms of a previously granted fixed-price stock option. Pursuant to FIN 44, we recognized stock-based compensation expense (a sub-category of general and administrative expenses) arising from modifications made to previously issued stock options in the condensed consolidated statements of operations of $0.3 million, $0.2 million, $0.4 million and $0.2 million in the Current Quarter, Prior Quarter, Current Period and Prior Period, respectively.

Pro forma information regarding net income and earnings per share is required by SFAS No. 123 and has been determined as if we had accounted for our employee and director stock options under the fair value method of the statement. The fair value for these options was estimated at the date of grant using a Black-Scholes option pricing model with the following weighted-average assumptions for the periods presented: interest rates (zero-coupon U.S. government issues with a remaining life equal to the expected term of the options) ranging from 3.81% to 4.18%, dividend yields ranging from 0.82% to 1.22%, and volatility factors for the expected market price of our common stock ranging from 0.30 to 0.33. We used a weighted-average expected life of the options of five years for each of the periods presented.

Presented below is pro forma financial information assuming Chesapeake had applied the fair value method under SFAS No. 123:

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

For purposes of the pro forma disclosures, the estimated fair value of the options is amortized to expense over the option vesting period, which is four years for employee options.

In December 2004, the Financial Accounting Standards Board issued SFAS 123(R), Share-Based Payment, a revision of SFAS 123, Accounting for Stock-Based Compensation. This statement establishes standards for the accounting for transactions in which an entity exchanges its equity instruments for goods or services by requiring a public entity to measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. That cost will be recognized over the period during which an employee is required to provide services in exchange for the award. The fair value of employee stock options will be estimated using option-pricing models. Excess tax benefits will be recognized as an addition to paid-in capital. Cash retained as a result of those excess tax benefits will be presented in the statement of cash flows as financing cash inflows. The write-off of deferred tax assets relating to unrealized tax benefits associated with recognized compensation cost will be recognized as income tax expense unless there are excess tax benefits from previous awards remaining in paid-in capital to which it can be offset. This statement was initially effective as of the beginning of the first interim or annual reporting period that begins after June 15, 2005. However, in April 2005, the Securities and Exchange Commission adopted a new rule that amends the compliance dates for SFAS 123(R). The new rule allows the implementation of SFAS 123(R) at the beginning of the annual reporting period that begins after June 15, 2005, instead of the next reporting period. The SEC’s new rule only changes the date for compliance with the standard.

Chesapeake will implement SFAS 123(R) in the first quarter of 2006, and the Black-Scholes option pricing model will be used to value the stock options as of the grant date. Based on the stock options outstanding and unvested at June 30, 2005, we do not believe the new accounting requirement will have a significant impact on future results of operations.

Restricted Stock. Chesapeake began issuing shares of restricted common stock to employees in January 2004. The total value of restricted shares granted is recorded as unearned compensation in stockholders’ equity based on the fair market value of the shares on the date of grant. This value is amortized over the vesting period, which is four years from the date of grant. To the extent amortization of compensation cost relates to employees directly involved in acquisition, exploration and development activities, such amounts are capitalized to oil and gas properties. Amounts not capitalized to oil and gas properties are recognized in stock-based compensation expense (a sub-category of general and administrative costs).

Critical Accounting Policies

We consider accounting policies related to hedging, oil and gas properties, income taxes and business combinations to be critical policies. These policies are summarized in Management’s Discussion and Analysis of Financial Condition and Results of Operations in our annual report on Form 10-K for the year ended December 31, 2004.

2. Financial Instruments and Hedging Activities

Oil and Gas Hedging Activities

Our results of operations and operating cash flows are impacted by changes in market prices for oil and gas. To mitigate a portion of the exposure to adverse market changes, we have entered into various derivative instruments. As of June 30, 2005, our oil and gas derivative instruments were comprised of swaps, cap-swaps, basis protection swaps, call options and collars. These instruments allow us to predict with greater certainty the effective oil and gas prices to be received for our hedged production. Although derivatives often fail to achieve 100% effectiveness for accounting purposes, we believe our derivative instruments continue to be highly effective in achieving the risk management objectives for which they were intended.

• For swap instruments, Chesapeake receives a fixed price for the hedged commodity and pays a floating market price to the counterparty. The fixed-price payment and the floating-price payment are netted, resulting in a net amount due to or from the counterparty.

CHESAPEAKE ENERGY CORPORATION AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

• For cap-swaps, Chesapeake receives a fixed price and pays a floating market price. The fixed price received by Chesapeake includes a premium in exchange for a “cap” limiting the counterparty’s exposure. In other words, there is no limit to Chesapeake’s exposure but there is a limit to the downside exposure of the counterparty.

• Basis protection swaps are arrangements that guarantee a price differential for oil or gas from a specified delivery point. Chesapeake receives a payment from the counterparty if the price differential is greater than the stated terms of the contract and pays the counterparty if the price differential is less than the stated terms of the contract.

• For call options, Chesapeake receives a cash premium from the counterparty in exchange for the sale of a call option. If the market price exceeds the fixed price of the call option, then Chesapeake pays the counterparty such excess. If the market price settles below the fixed price of the call option, no payment is due from Chesapeake.

• Collars contain a fixed floor price (put) and ceiling price (call). If the market price exceeds the call strike price or falls below the put strike price, Chesapeake receives the fixed price and pays the market price. If the market price is between the call and the put strike price, no payments are due from either party.

Chesapeake enters into counter-swaps from time to time for the purpose of locking-in the value of a swap. Under the counter-swap, Chesapeake receives a floating price for the hedged commodity and pays a fixed price to the counterparty. The counter-swap is 100% effective in locking-in the value of a swap since subsequent changes in the market value of the swap are entirely offset by subsequent changes in the market value of the counter-swap. We refer to this locked-in value as a locked swap. At the time Chesapeake enters into a counter-swap, Chesapeake removes the original swap’s designation as a cash flow hedge and classifies the original swap as a non-qualifying hedge under SFAS 133. The reason for this new designation is that collectively the swap and the counter-swap no longer hedge the exposure to variability in expected future cash flows. Instead, the swap and counter-swap effectively lock-in a specific gain (or loss) that will be unaffected by subsequent variability in oil and gas prices. Any locked-in gain or loss is recorded in accumulated other comprehensive income and reclassified to oil and gas sales in the month of related production.

With respect to counter-swaps that are designed to lock-in the value of cap-swaps, the counter-swap is effective in locking-in the value of the cap-swap until the floating price reaches the cap (or floor) stipulated in the cap-swap agreement. The value of the counter-swap will increase (or decrease), but in the opposite direction, as the value of the cap-swap decreases (or increases) until the floating price reaches the pre-determined cap (or floor) stipulated in the cap-swap agreement. However, because of the written put option embedded in the cap-swap, the changes in value of the cap-swap are not completely effective in offsetting changes in value of the corresponding counter-swap. Changes in the value of the cap-swaps and the counter-swaps are recorded as adjustments to oil and gas sales.

In accordance with FASB Interpretation No. 39, to the extent that a legal right of setoff exists, Chesapeake nets the value of its derivative arrangements with the same counterparty in the accompanying condensed consolidated balance sheets.

Chesapeake enters into basis protection swaps for the purpose of locking-in a price differential for oil or gas from a specified delivery point. We currently have basis protection swaps covering four different delivery points which correspond to the actual prices we receive for much of our gas production. By entering into these basis protection swaps, we have effectively reduced our exposure to market changes in future gas price differentials. As of June 30, 2005, the fair value of our basis protection swaps was $128.1 million. As of June 30, 2005, our basis protection swaps cover approximately 44% of our anticipated remaining gas production in 2005, 28% in 2006, 25% in 2007, 22% in 2008 and 16% in 2009.

Gains or losses from derivative transactions are reflected as adjustments to oil and gas sales on the condensed consolidated statements of operations. Realized gains (losses) included in oil and gas sales were ($44.4) million, ($55.3) million, ($4.0) million and ($29.7) million in the Current Quarter, Prior Quarter, Current Period and Prior Period, respectively. Pursuant to SFAS 133, certain derivatives do not qualify for designation as cash flow hedges. Changes in the fair value of these non-qualifying derivatives that occur prior to their maturity (i.e., temporary

fluctuations in value) are reported currently in the consolidated statements of operations as unrealized gains (losses) within oil and gas sales. Unrealized gains (losses) included in oil and gas sales were $84.1 million, ($20.2) million, ($33.1) million and ($34.2) million, in the Current Quarter, Prior Quarter, Current Period and Prior Period, respectively.

Following provisions of SFAS 133, changes in the fair value of derivative instruments designated as cash flow hedges, to the extent they are effective in offsetting cash flows attributable to the hedged risk, are recorded in other comprehensive income until the hedged item is recognized in earnings. Any change in fair value resulting from ineffectiveness is recognized currently in oil and gas sales as unrealized gains (losses). We recorded a gain (loss) on ineffectiveness of $1.2 million, ($8.0) million, $0.6 million and ($15.2) million in the Current Quarter, Prior Quarter, Current Period and Prior Period, respectively.

The estimated fair values of our oil and gas derivative instruments as of June 30, 2005 and December 31, 2004 are provided below. The associated carrying values of these instruments are equal to the estimated fair values.

Derivative assets (liabilities):
Fixed-price gas swaps	$	(77,690	)	$	57,073

(a) After adjusting for the remaining $1.6 million and $3.2 million premium paid to Chesapeake by the counterparty, the cumulative unrealized loss related to these call options as of June 30, 2005 and December 31, 2004 was $4.3 million and $2.6 million, respectively.

Based upon the market prices at June 30, 2005, we expect to transfer approximately $51.5 million (net of income taxes) of the loss included in the balance in accumulated other comprehensive income to earnings during the next 12 months when the transactions actually close. All transactions hedged as of June 30, 2005 are expected to mature by December 31, 2007, with the exception of our basis protection swaps which extend through 2009.

We have two secured hedging facilities, each of which permits us to enter into cash-settled natural gas and oil commodity transactions, valued by the counterparty, for up to $500 million. The scheduled maturity date for these facilities is May 2010. Outstanding transactions under each facility are collateralized by certain of our oil and gas properties that do not secure any of our other obligations. One of the hedging facilities is subject to an annual fee of 0.30% of the maximum total capacity, and each of them has a 1.0% exposure fee, which is assessed quarterly on the average of the daily negative fair market value amounts, if any, during the quarter. As of June 30, 2005, the fair market value of the natural gas and oil hedging transactions was a liability of $42.8 million under one of the facilities and an asset of $45.9 million under the other facility. The hedging facilities contain the standard representations and default provisions that are typical of such agreements. The agreements also contain various restrictive provisions which govern the aggregate gas and oil production volumes that we are permitted to hedge under all of our agreements at any one time.

Interest Rate Derivatives

We utilize hedging strategies to manage our exposure to changes in interest rates. To the extent interest rate swaps have been designated as fair value hedges, changes in the fair value of the derivative instrument and the corresponding debt are reflected as adjustments to interest expense in the corresponding months covered by the derivative agreement. Changes in the fair value of derivative instruments not qualifying as fair value hedges are recorded currently as adjustments to interest expense.

As of June 30, 2005, the following interest rate swap was used to convert a portion of our long-term fixed-rate debt to floating-rate debt was outstanding:

Term	Notional Amount		Fixed Rate		Floating Rate	Fair Value Gain (Loss)
						($ in thousands)
September 2004 – August 2012	$	75,000,000	9.000	%	6 month LIBOR plus 452 basis points	$	(714	)

Subsequent to June 30, 2005, we entered into the following interest rate swaps (which qualify as fair value hedges) to convert a portion of our long-term fixed-rate debt to floating-rate debt:

Term	Notional Amount		Fixed Rate		Floating Rate
July 2005 – January 2015	$	150,000,000	7.750	%	6 month LIBOR plus 289 basis points
July 2005 – June 2014	$	150,000,000	7.500	%	6 month LIBOR plus 282 basis points
August 2005 – August 2014	$	200,000,000	7.000	%	6 month LIBOR plus 205.5 basis points

In the Current Quarter and Current Period, we closed various interest rate swaps for gains totaling $4.3 million and $5.1 million, respectively. These interest rate swaps were designated as fair value hedges, and the settlement amounts received will be amortized as a reduction to realized interest expense over the remaining terms of the related senior notes.

In March 2004, Chesapeake entered into an interest rate swap which required Chesapeake to pay a fixed rate of 8.68% while the counterparty paid Chesapeake a floating rate of six month LIBOR plus 0.75% on a notional amount of $142.7 million. On March 15, 2005, we elected to terminate the interest rate swap and paid $31.8 million to the counterparty.

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. We have determined the estimated fair values by 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. We estimate the fair value of our long-term fixed-rate debt using primarily quoted market prices. Our carrying amount for such debt, excluding discounts or premiums related to interest rate derivatives, at June 30, 2005 and December 31, 2004 was $3,664.1 million and $3,014.1 million, respectively, compared to approximate fair values of $3,865.7 million and $3,281.1 million, respectively. The carrying amounts for our convertible preferred stock as of June 30, 2005 and December 31, 2004 were $905.8 million and $490.9 million, respectively, compared to approximate fair values of $994.8 million and $533.7 million, respectively.

Concentration of Credit Risk

A significant portion of our liquidity is concentrated in derivative instruments that enable us to hedge a portion of our exposure to price volatility from producing oil and natural gas. These arrangements expose us to credit risk from our counterparties. Other financial instruments which potentially subject us to concentrations of credit risk consist principally of investments in equity instruments and accounts receivable. Our accounts receivable are primarily from purchasers of oil and natural gas products and exploration and production companies which own interests in properties we operate. This industry concentration has the potential to impact our overall exposure to credit risk, either positively or negatively, in that our customers may be similarly affected by changes in economic, industry or other conditions. We generally require letters of credit for receivables from customers which are judged to have sub-standard credit, unless the credit risk can otherwise be mitigated.

3. Contingencies and Commitments

Litigation

Chesapeake is currently involved in various disputes incidental to its business operations. 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 our consolidated financial position, results of operations or cash flows.

Employment Agreements with Officers

Chesapeake has employment agreements with its chief executive officer, chief operating officer, chief financial officer and various other senior management personnel, which provide for annual base salaries, bonus compensation and various benefits. The agreements provide for the continuation of salary and benefits for varying terms in the event of termination of employment without cause. The agreements with the chief executive officer and chief operating officer have terms of five years commencing July 1, 2005. The term of each agreement is automatically extended for one additional year on each January 31 unless the company provides 30 days notice of non-extension. The agreements with the chief financial officer and other senior managers expire on September 30, 2006. The company’s employment agreements with the executive officers provide for payments in the event of a change in control. The chief executive officer and chief operating officer are each entitled to receive a payment in the amount of three times his base salary, the prior year’s bonus compensation and the value of benefits provided during the prior year, plus a tax gross-up payment, and the chief financial officer and other officers are each entitled to receive a payment in the amount of two times his or her base salary and bonuses paid during the prior year.

Environmental Risk

Due to the nature of the oil and gas business, Chesapeake and its subsidiaries are exposed to possible environmental risks. Chesapeake has implemented various policies and procedures to avoid environmental contamination and risks from environmental contamination. Chesapeake conducts periodic reviews, on a company-wide basis, to identify changes in our environmental risk profile. These reviews evaluate whether there is a contingent liability, its amount, and the likelihood that the liability will be incurred. The amount of any potential liability is determined by considering, among other matters, incremental direct costs of any likely remediation and the proportionate cost of employees who are expected to devote a significant amount of time directly to any possible remediation effort. We manage our exposure to environmental liabilities on properties to be acquired by identifying existing problems and assessing the potential liability. Depending on the extent of an identified environmental problem, Chesapeake may exclude a property from the acquisition, require the seller to remediate the property to our satisfaction, or agree to assume liability for the remediation of the property. Chesapeake has historically not experienced any significant environmental liability, and is not aware of any potential material environmental issues or claims at June 30, 2005.

Other Commitments

Chesapeake’s wholly owned subsidiary, Nomac Drilling Company, has contracted to acquire 18 rigs to be constructed during 2005 and 2006. The total cost of the rigs will be approximately $150 million.

4. Net Income Per Share

Statement of Financial Accounting Standards No. 128, Earnings Per Share, requires presentation of “basic” and “diluted” earnings per share, as defined, on the face of the statements of operations for all entities with complex capital structures. SFAS 128 requires a reconciliation of the numerator and denominator of the basic and diluted EPS computations.

The following securities were not included in the calculation of diluted earnings per share, as the effect was antidilutive:

• For the Current Quarter, the Prior Quarter, Current Period and Prior Period, outstanding options to purchase 0.2 million, 0.1 million, 0.1 million and 0.2 million shares of common stock at a weighted-average exercise price of $26.53, $26.73, $27.88 and $19.93, respectively, were antidilutive because the exercise prices of the options were greater than the average market price of the common stock during the respective periods.

• For each of the Prior Quarter and the Prior Period, outstanding warrants to purchase 0.3 million shares of common stock at a weighted-average exercise price of $15.72 were antidilutive because the exercise prices of the warrants were greater than the average market price of the common stock during the period.

• For the Current Quarter and Current Period, diluted shares do not include the common stock equivalent of 4.125% preferred stock outstanding prior to conversion (convertible into 2,613,403 and 2,657,704 shares, respectively) as the effect was antidilutive, and the preferred stock dividend adjustment to net income does not include $5.1 million and $5.5 million, respectively, of dividends and loss on conversion related to these preferred shares.

There were no repurchases or exchanges of Chesapeake debt in the Prior Quarter.

The senior note indentures permit us to redeem the senior notes at any time at specified make-whole or redemption prices. The indentures contain covenants limiting our ability and our restricted subsidiaries’ ability to incur additional indebtedness; pay dividends on our capital stock or redeem, repurchase or retire our capital stock or subordinated indebtedness; make investments and other restricted payments; incur liens; engage in transactions with affiliates; sell assets and consolidate, merge or transfer assets.

Chesapeake is a holding company and owns no operating assets and has no significant operations independent of its subsidiaries. Our obligations under our outstanding senior notes have been fully and unconditionally guaranteed, on a joint and several basis, by all of our wholly owned subsidiaries.

We have a $1.25 billion syndicated revolving bank credit facility which matures in January 2010. As of June 30, 2005, we had $455.0 million of outstanding borrowings under our facility and utilized $53.1 million of the facility for various letters of credit. Borrowings under our facility are collateralized by certain producing oil and gas properties and bear interest at either (i) the greater of the reference rate of Union Bank of California, N.A. or the federal funds effective rate plus 0.50% or (ii) the London Interbank Offered Rate (LIBOR), at our option, plus a margin that varies according to our senior unsecured long-term debt ratings. The collateral value and borrowing base are determined periodically. The unused portion of the facility is subject to an annual commitment fee that also varies according to our senior unsecured long-term debt ratings. Currently, the annual commitment fee rate is 0.30%. Interest is payable quarterly or, if LIBOR applies, it may be payable at more frequent intervals.

The credit facility agreement contains various covenants and restrictive provisions which govern our ability to incur additional indebtedness, sell properties, purchase or redeem our capital stock, make investments or loans, and create liens. The credit facility agreement requires us to maintain a fixed charge coverage ratio (as defined) of at least 2.5 to 1 and an indebtedness to EBITDA ratio (as defined) not to exceed 3.5 to 1. At June 30, 2005, our fixed charge coverage ratio was 5.79 to 1 and our indebtedness to EBITDA ratio was 2.25 to 1. If we should fail to perform our obligations under these and other covenants, the revolving credit commitment could be terminated and any outstanding borrowings under the facility could be declared immediately due and payable. Such acceleration, if involving a principal amount of $10 million ($50 million in the case of our 6.625% Senior Notes due 2016 and 6.25% Senior Notes due 2018), would constitute an event of default under our senior note indentures which could in turn result in the acceleration of a significant portion of our senior note indebtedness. The credit facility agreement also has cross default provisions that apply to other indebtedness we may have with an outstanding principal amount in excess of $50 million.

6. Segment Information

In accordance with Statement of Financial Accounting Standards No. 131, Disclosures about Segments of an Enterprise and Related Information, we have identified two reportable operating segments. These segments are managed separately because of the nature of their products and services. Chesapeake’s two segments are the exploration and production segment and the marketing segment. The exploration and production segment is responsible for finding and producing natural gas and crude oil. The marketing segment is responsible for gathering, processing, transporting, and selling natural gas and crude oil production primarily from Chesapeake operated wells. Revenues from the marketing segment’s sale of oil and gas related to Chesapeake’s ownership interests are reflected as exploration and production revenues. Such amounts totaled $463.9 million and $310.3 million for the Current Quarter and the Prior Quarter, respectively, and $869.1 million and $582.4 million for the Current Period and the Prior Period, respectively.

Management evaluates the performance of our segments based upon income before income taxes.

CHESAPEAKE ENERGY CORPORATION AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - (Continued)

During the Current Period, we have recorded approximately $252 million of deferred tax liability to reflect the tax effect of the cost paid in excess of the tax basis acquired on certain acquisitions.

8. Recently Issued Accounting Standards

The Financial Accounting Standards Board and the Securities and Exchange Commission recently issued the following standards which were reviewed by Chesapeake to determine the potential impact on our financial statements upon adoption.

In December 2004, the Financial Accounting Standards Board issued SFAS 123(R), Share-Based Payment, a revision of SFAS 123, Accounting for Stock-Based Compensation. This statement establishes standards for the accounting for transactions in which an entity exchanges its equity instruments for goods or services by requiring a public entity to measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. This statement is effective as of the beginning of the first annual reporting period that begins after June 15, 2005. The effect of SFAS 123 (R) is more fully described in Note 1.

In March 2005, the FASB issued FASB Interpretation No. (FIN) 47, Accounting for Conditional Asset Retirement Obligations. FIN 47 specifies the accounting treatment for conditional asset retirement obligations under the provisions of Statement of Financial Accounting Standards No. 143. FIN 47 is effective no later than the end of the fiscal year ending after December 15, 2005. We plan to adopt this statement effective December 31, 2005. Implementation of FIN 47 is not expected to have a material effect on our financial statements.

9. Subsequent Events

On July 6, 2005, we completed cash tender offers for our 8.125% Senior Notes due 2011 and 9.0% Senior Notes due 2012. Subsequent to June 30, 2005, approximately $0.3 million was used to purchase $0.1 million of 8.125% Senior Notes due 2011 and $0.2 million of 9.0% Senior Notes due 2012. Subsequent to the expiration of these tender offers, we notified the trustee of our intention to redeem the remaining 8.125% and 9.0% Senior Notes on August 17, 2005 based on the make-whole redemption provisions in the indentures.

In July 2005, we exchanged 2,225,111 shares of our common stock for 34,452 shares of our 4.125% cumulative convertible preferred stock.

On July 18, 2005, we purchased $249.5 million of Barnett Shale natural gas assets from Hallwood Energy III L.P. We used our revolving bank credit facility to fund this acquisition.

Subsequent to June 30, 2005, we obtained a 49% interest in Mountain Drilling Company, a newly formed venture with a New York-based investment banking firm in which Chesapeake and its partner have each invested $25 million to secure four specialty rigs for drilling in urban areas or in areas of special environmental sensitivity.

Subsequent to June 30, 2005, we have agreed to acquire $160 million of natural gas assets in the East Texas and Permian Basin regions in three transactions with three private companies.

Chesapeake is the third largest independent producer of natural gas in the U.S. and owns interests in approximately 21,500 producing oil and gas wells. Our primary operating area is the Mid-Continent region of the United States, which includes Oklahoma, Arkansas, Kansas and the Texas Panhandle, and we are building significant secondary operating areas in the South Texas and Texas Gulf Coast regions, the Permian Basin of western Texas and eastern New Mexico, the Barnett Shale area of north-central Texas and the Ark-La-Tex areas of eastern Texas and northern Louisiana.

18

Our revenues, operating results, profitability and future growth depend on our ability to find, develop and acquire oil and gas reserves that are economically recoverable based on prevailing prices for natural gas and oil. We favor gas over oil, strive to establish regional dominance in our operating areas, have grown through a combination of drilling and acquisitions and manage price risk through opportunistic oil and natural gas hedging. We believe we have among the largest onshore U.S. inventory of leasehold and 3-D seismic data (approximately 4.1 million and 10.8 million net acres, respectively) with a nine year drilling backlog of approximately 14,000 locations.

Oil and natural gas production for the Current Quarter was 113.2 bcfe, an increase of 26.7 bcfe, or 31%, over the 86.5 bcfe produced in the Prior Quarter. We have increased our production for 16 consecutive quarters. During these 16 quarters, Chesapeake’s U.S. production has increased 214%, for an average compound quarterly growth rate of 7.4% and an average compound annual growth rate of 33.1%.

In addition to increased oil and natural gas production, the prices we received were higher in the Current Quarter than in the Prior Quarter. On a natural gas equivalent basis, weighted average prices (excluding the effect of unrealized gains or losses on derivatives) were $6.08 per mcfe in the Current Quarter compared to $4.85 per mcfe in the Prior Quarter. The increase in prices resulted in an increase in revenue of $139.2 million, and increased production resulted in an increase in revenue of $129.3 million, for a total increase in revenue of $268.5 million (excluding the effect of unrealized gains or losses on derivatives). In each of the core operating areas where Chesapeake sells its oil and natural gas, established marketing and transportation infrastructures exist thereby contributing to relatively high wellhead price realizations for our production.

Chesapeake began 2005 with estimated proved reserves of 4,902 bcfe and ended the Current Quarter with 5,850 bcfe, an increase of 948 bcfe, or 19%. During the 2005 first half, we replaced 218 bcfe of production with an estimated 1,166 bcfe of new proved reserves, for a reserve replacement rate of 535%. Reserve replacement through the drillbit was 583 bcfe, or 268% of production (including 43 bcfe from positive performance revisions and 25 bcfe from oil and natural gas price increases), or 50% of the total increase. Reserve replacement through acquisitions was 583 bcfe, or 267% of production, or 50% of the total increase.

During the Current Quarter, Chesapeake drilled 224 (162 net) operated wells and participated in another 296 (34 net) wells operated by other companies. The company’s drilling success rate was 97% for operated wells and 98% for non-operated wells. During the quarter, Chesapeake invested $400 million in operated wells (using an average of 73 operated rigs), $77 million in non-operated wells (using an average of approximately 65 non-operated rigs) and $52 million in acquiring new 3-D seismic data and new leasehold (excluding leasehold acquired through acquisitions). Our acquisition expenditures totaled $778 million during the Current Quarter (including amounts paid for unproved leasehold and excluding $132 million of deferred taxes in connection with certain corporate acquisitions).

We have taken several actions to mitigate higher field service costs, ensure our timely access to drilling rigs and participate in service industry growth. Through our wholly owned subsidiary Nomac Drilling Corporation, we have 14 rigs dedicated to drilling Chesapeake-operated wells and we have an additional 18 rigs on order for delivery over the next year. In addition, we have entered into drilling contracts for the use of 20 rigs currently being built or refurbished by private drilling companies, to be available to us in 2005 and 2006. We also have invested approximately $43 million in the common stock of publicly held Pioneer Drilling Company over the past two years, and now hold approximately 17% of its outstanding common stock. At June 30, 2005, our Pioneer shares had a market value of $117.5 million. We also have invested $15 million in the common stock of DHS Drilling Company, a Casper, Wyoming-based drilling company which has four rigs operating in the Rocky Mountains and which will expand to ten rigs over the next several months. At June 30, 2005, our ownership percentage was approximately 45%. Subsequent to June 30, 2005, we obtained a 49% interest in Mountain Drilling Company, a newly formed venture with a New York-based investment banking firm in which Chesapeake and its partner have each invested $25 million to secure four specialty rigs for drilling in urban areas or in areas of special environmental sensitivity.

As of June 30, 2005, the company’s debt as a percentage of total capitalization (total capitalization is the sum of debt and stockholders’ equity) was 52%, compared to 49% as of December 31, 2004. During the Current Period, we received net proceeds of $1,627.9 million through issuances of $460 million of preferred equity (series 2005

19

5.0% convertible preferred stock), $600 million principal amount of 6.625% Senior Notes due 2016 and $600 million principal amount of 6.25% Senior Notes due 2018. We exchanged 45,000 shares of our outstanding 4.125% preferred stock for 2,911,250 shares of common stock, and holders of our 6.0% preferred stock converted 1,735 shares into 8,432 shares of common stock. Additionally, we purchased and retired $11.0 million principal amount of 8.375% Senior Notes due 2008, $237.8 million principal amount of 8.125% Senior Notes due 2011 and $298.9 million principal amount of 9.0% Senior Notes due 2012 which resulted in an aggregate loss on repurchases or exchanges of Chesapeake debt of $69.3 million for the Current Period. As a result of our debt transactions during the Current Period, we have extended the average maturity of our long-term debt to over ten years and have lowered our average interest rate to approximately 6.9%.

We intend to continue to focus on improving the strength of our balance sheet. We believe our business strategy and operational performance will lead to an investment grade credit rating for our unsecured debt in the future.

Liquidity and Capital Resources

Sources of Liquidity

Our primary source of liquidity to meet operating expenses and fund capital expenditures (other than for certain acquisitions) is cash flow from operations. Based on our current production, price and expense assumptions, we expect cash flow from operations will exceed our drilling capital expenditures in 2005. Our budget for drilling, land and seismic activities during 2005 is currently between $1.9 billion and $2.1 billion. We believe this level of exploration and development will be sufficient to increase our reserves in 2005 and achieve our goal of a 10% to 20% increase in production over 2004 production (inclusive of acquisitions completed or scheduled to close in 2005 through the filing date of this report but without regard to any additional acquisitions that may be completed in 2005). However, higher drilling and field operating costs, drilling results that alter planned development schedules, acquisitions or other factors could cause us to revise our drilling program, which is largely discretionary. Any cash flow from operations not needed to fund our drilling program will be available for acquisitions, debt repayment or other general corporate purposes in 2005.

Cash provided by operating activities (exclusive of changes in assets and liabilities) was $1,018.7 million in the Current Period compared to $641.7 million in the Prior Period. The $377.0 million increase was primarily due to higher realized prices and higher volumes of oil and gas production. We expect that 2005 production volumes will be higher than in 2004 and that cash provided by operating activities in 2005 will exceed 2004 levels. While a precipitous decline in gas prices in the remainder of 2005 would significantly affect the amount of cash flow that would be generated from operations, we have 47% of our expected oil production for the remainder of 2005 hedged at an average NYMEX price of $52.22 per barrel of oil and 59% of our expected natural gas production for the remainder of 2005 hedged at an average NYMEX price of $6.65 per mcf. This level of hedging provides greater certainty of the cash flow we will receive for a substantial portion of our remaining 2005 production. Depending on changes in oil and gas futures markets and management’s view of underlying oil and natural gas supply and demand trends, however, we may increase or decrease our current hedging positions.

Based on fluctuations in natural gas and oil prices, our hedging counterparties may require us to deliver cash collateral or other assurances of performance from time to time. At June 30, 2005 and August 4, 2005, we had issued $50 million and $51 million, respectively, of letters of credit securing our performance of hedging contracts. To mitigate the liquidity impact of those collateral requirements, we have negotiated caps on the amount of collateral that we might be required to post with four of our counterparties. All of our existing commodity hedges that are not under our secured hedge facilities (described below under Contractual Obligations) are with these counterparties and the maximum amount of collateral that we would be required to post with these counterparties is capped at $180 million.

A significant source of liquidity is our $1.25 billion syndicated revolving bank credit facility which matures in January 2010. At August 4, 2005, there was $264.9 million of borrowing capacity available under the revolving bank credit facility. We use the facility to fund daily operating activities and acquisitions as needed. We borrowed $2,419 million and repaid $2,023 million in the Current Period, and we borrowed $767.0 million and repaid $611.0 million in the Prior Period under our bank credit facility. We incurred $4.6 million and $8.3 million of financing costs related to our revolving credit facility in the Current Period and the Prior Period, respectively, as a result of amendments to the credit agreement.

20

We believe that our available cash, cash provided by operating activities and funds available under our revolving bank credit facility will be sufficient to fund our operating, interest and general and administrative expenses, our capital expenditure budget, our short-term contractual obligations and dividend payments at current levels for the foreseeable future. Our revolving bank credit facility and secured hedge facilities do not contain material adverse change or adequate assurance clauses. Although the applicable interest rates and commitment fees in our bank credit facility fluctuate slightly based on our long-term senior unsecured credit ratings, the bank facility and the secured hedge facilities do not contain provisions which would trigger an acceleration of amounts due under the facilities or a requirement to post additional collateral in the event of a downgrade of our credit ratings.

The public and institutional markets have been our principal source of long-term financing for acquisitions. We have sold debt and equity in both public and private offerings in the past, and we expect that these sources of capital will continue to be available to us in the future for acquisitions. Nevertheless, we caution that ready access to capital on reasonable terms and the availability of desirable acquisition targets at attractive prices are subject to many uncertainties, as explained under “Risk Factors” in Item 1—Business of our Form 10-K for the year ended December 31, 2004.

The following table reflects the proceeds from sales of securities we issued in the Current Period and the Prior Period ($ in millions):

	For the Six Months Ended June 30,
	2005				2004

We have an effective $600 million universal shelf registration statement on file with the Securities and Exchange Commission. Securities issued under this shelf may be in the form of common stock, preferred stock, depository shares representing fractional shares of preferred stock or debt securities of Chesapeake. A prospectus supplement will be prepared at the time of a debt or equity offering and will contain specific information about the security issued and the use of proceeds. No securities have been issued under this shelf registration statement.

We paid dividends on our common stock of $27.9 million and $16.0 million in the Current Period and the Prior Period, respectively. The Board of Directors voted on June 10, 2005 to increase the annual dividend per common share by 11%, from $0.18 to $0.20. The first dividend at this higher rate was paid on July 15, 2005 to common shareholders of record on July 1, 2005. We paid dividends on our preferred stock of $10.9 million and $18.9 million in the Current Period and the Prior Period, respectively. We received $11.6 million and $6.6 million from the exercise of employee and director stock options and warrants in the Current Period and the Prior Period, respectively.

Outstanding payments from certain disbursement accounts in excess of funded cash balances where no legal right of set-off exists increased by $75.2 million and $11.1 million in the Current Period and the Prior Period, respectively. All disbursements are funded on the day they are presented to our bank using available cash on hand or draws on our credit facility.

Historically, we have used significant funds to purchase and retire outstanding senior notes issued by Chesapeake. The following table shows our purchases and exchanges of senior notes ($ in millions):

(b) We issued $72.8 million of our 7.75% Senior Notes and $470.5 million of our 6.875% Senior Notes.

Cash used in investing activities increased to $2,539.9 million during the Current Period, compared to $1,599.5 million during the Prior Period. The following table shows our capital expenditures during these periods ($ in millions):

	Six Months Ended June 30,

Divestitures of oil and gas properties		(0.1	)		(0.3	)
Other		—			(0.3	)
Total	$	2,539.9		$	1,599.5

Our accounts receivable are primarily from purchasers of oil and natural gas ($356.5 million at June 30, 2005) and exploration and production companies which own interests in properties we operate ($73.7 million at June 30, 2005). This industry concentration has the potential to impact our overall exposure to credit risk, either positively or negatively, in that our customers may be similarly affected by changes in economic, industry or other conditions. We generally require letters of credit for receivables from customers which are judged to have sub-standard credit, unless the credit risk can otherwise be mitigated.

Our liquidity is not dependent on the use of off-balance sheet financing arrangements, such as the securitization of receivables or obtaining access to assets through special purpose entities. We have not relied on off-balance sheet financing arrangements in the past and we do not intend to rely on such arrangements in the future as a source of liquidity. We are not a commercial paper issuer.

Investing and Financing Transactions

(a) We paid $16.3 million of the purchase amount in 2004.

(b) During the Current Period, we paid the remaining $57 million of the purchase price related to an acquisition transaction with Hallwood Energy Corporation in the fourth quarter 2004.

During 2004 and continuing in 2005, we have taken several steps to improve our capital structure. These transactions enabled us to extend our average maturity of long-term debt to over ten years with an average interest rate of approximately 6.9%. Achieving a debt-to-total-capitalization ratio of below 50% and reducing debt per mcfe of proved reserves remain key goals of our business strategy.

22

We completed the following significant financing transactions in the Current Period:

First Quarter 2005

• Amended our revolving bank credit facility to increase the committed borrowing base to $1.25 billion and extended the maturity of the facility to January 2010.

• Completed a private purchase of $11.0 million of our 8.375% Senior Notes due 2008 for $12.0 million (including a premium of $0.8 million).

Second Quarter 2005

• Completed private offerings of $600 million principal amount of 6.625% Senior Notes due 2016 and 4,600,000 shares of 5.0% convertible preferred stock having a liquidation preference of $100 per share. Net proceeds of $1,031.5 million from these transactions were used to finance acquisitions totaling $459 million that closed in the second quarter of 2005 and to repay debt incurred under our credit facility to temporarily finance the BRG and the Laredo acquisitions completed in the first quarter.

• Completed a private placement of $600 million of 6.25% Senior Notes due 2018. Net proceeds of approximately $596.4 million were used to fund our purchases in June 2005 of $237.8 million of our 8.125% Senior Notes due 2011 for $255.3 million (including a premium of $16.8 million and transaction costs of $0.7 million) and $298.9 million of our 9.0% Senior Notes due 2012 for $341.0 million (including a premium of $41.3 million and transaction costs of $0.8 million) pursuant to tender offers for the 8.125% and 9.0% Senior Notes. We acquired a total of $237.9 million principal amount of 8.125% Senior Notes due 2011 and $299.1 million, principal amount of 9.00% senior notes due 2012, representing 96.9% and 99.7%, respectively, of the amounts outstanding, in the tender offers, which expired on July 6, 2005. Subsequent to the expiration of these tender offers, we notified the trustee of our intention to redeem the remaining 8.125% and 9.0% Senior Notes on August 17, 2005 based on the make-whole redemption provisions in the indentures.

• Completed a private exchange of 45,000 shares of our outstanding 4.125% preferred stock for 2,911,250 shares of common stock. No cash was received or paid in connection with this transaction.

Contractual Obligations

We currently have a $1.25 billion syndicated revolving bank credit facility which matures in January 2010. The credit facility was increased from $600 million to $1.25 billion in January 2005. As of June 30, 2005, we had $455.0 million of outstanding borrowings under this facility and had utilized $53.1 million of the facility for various letters of credit. Borrowings under the facility are collateralized by certain producing oil and gas properties and bear interest at either (i) the greater of the reference rate of Union Bank of California, N.A., or the federal funds effective rate plus 0.50% or (ii) London Interbank Offered Rate (LIBOR), at our option, plus a margin that varies according to our senior unsecured long-term debt ratings. The collateral value and borrowing base are redetermined periodically. The unused portion of the facility is subject to an annual commitment fee that also varies according to our senior unsecured long-term debt ratings. Currently the annual commitment fee is 0.30%. Interest is payable quarterly or, if LIBOR applies, it may be payable at more frequent intervals.

The credit facility agreement contains various covenants and restrictive provisions which limit our ability to incur additional indebtedness, sell properties, purchase or redeem our capital stock, make investments or loans, and create liens. The credit facility agreement requires us to maintain a fixed charge coverage ratio (as defined) of at least 2.5 to 1 and an indebtedness to EBITDA ratio (as defined) not to exceed 3.5 to 1. At June 30, 2005, our fixed charge coverage ratio was 5.79 to 1 and our indebtedness to EBITDA ratio was 2.25 to 1. If we should fail to perform our obligations under these and other covenants, the revolving credit commitment could be terminated and

23

any outstanding borrowings under the facility could be declared immediately due and payable. Such acceleration, if involving a principal amount of $10 million ($50 million in the case of our 6.625% Senior Notes due 2016 and 6.25% Senior Notes due 2018), would constitute an event of default under our senior note indentures which could in turn result in the acceleration of a significant portion of our senior note indebtedness. The credit facility agreement also has cross default provisions that apply to other indebtedness we may have with an outstanding principal amount in excess of $50 million.

As of June 30, 2005, we owned 14 rigs dedicated to drilling wells operated by Chesapeake and have contracted to acquire 18 additional rigs to be constructed in 2005 and 2006. We expect to spend approximately $150 million to complete the rigs under construction.

Some of our commodity price and financial risk management arrangements require us to deliver cash collateral or other assurances of performance to the counterparties in the event that our payment obligations exceed certain levels. As of June 30, 2005, we were required to post $50 million of collateral in the form of letters of credit with respect to such derivative transactions. These collateral requirements were $51 million as of August 4, 2005. Future collateral requirements are uncertain and will depend on arrangements with our counterparties and fluctuations in natural gas and oil prices and interest rates. We currently have arrangements with four of our counterparties which limit the amount of collateral that we would be required to post with them to no more than $180 million in the aggregate.

We have two secured hedging facilities, each of which permits us to enter into cash-settled natural gas and oil commodity transactions, valued by the counterparty, for up to $500 million. The scheduled maturity date for these facilities is May 2010. Outstanding transactions under each facility are collateralized by certain of our oil and gas properties that do not secure any of our other obligations. One of the hedging facilities is subject to an annual fee of 0.30% of the maximum total capacity and each of them has a 1.0% exposure fee, which is assessed quarterly on the average of the daily negative fair market value amounts, if any, during the quarter. As of June 30, 2005, the fair market value of the natural gas and oil hedging transactions was a liability of $42.8 million under one of the facilities and an asset of $45.9 million under the other facility. The hedging facilities contain the standard representations and default provisions that are typical of such agreements. The agreements also contain various restrictive provisions which govern the aggregate gas and oil production volumes that we are permitted to hedge under all of our agreements at any one time.

Our subsidiary, Chesapeake Exploration Limited Partnership, is the borrower under our revolving bank credit facility and is the named party to our hedging facilities. The facilities are guaranteed by Chesapeake and all its other subsidiaries. Our revolving bank credit facility and secured hedge facilities do not contain material adverse change or adequate assurance clauses. Although the applicable interest rates and commitment fees in our bank credit facility fluctuate slightly based on our long-term senior unsecured credit ratings, the bank facility and the secured hedge facilities do not contain provisions which would trigger an acceleration of amounts due under the facilities or a requirement to post additional collateral in the event of a downgrade of our credit ratings.

In addition to outstanding revolving bank credit facility borrowings discussed above, as of June 30, 2005, our senior notes represented approximately $3.7 billion of our long-term debt and consisted of the following ($ in thousands):

8.375% Senior Notes due 2008	$	7,990
8.125% Senior Notes due 2011		7,583
9.0% Senior Notes due 2012		1,140
7.5% Senior Notes due 2013		363,823
7.0% Senior Notes due 2014		300,000
7.5% Senior Notes due 2014		300,000
7.75% Senior Notes due 2015		300,408
6.375% Senior Notes due 2015		600,000
6.625% Senior Notes due 2016		600,000
6.875% Senior Notes due 2016		670,437
6.25% Senior Notes due 2018		600,000
Discount on senior notes		(87,272	)
Premium for interest rate derivatives		6,820
	$	3,670,929

No scheduled principal payments are required on any of the senior notes until 2008, when $8.0 million is due.

Debt ratings for the senior notes are Ba3 by Moody’s Investor Service (positive outlook), BB- by Standard & Poor’s Ratings Services (positive outlook) and BB by Fitch Ratings.

24

Our senior notes are unsecured senior obligations of Chesapeake and rank equally with all of our other unsecured indebtedness. All of our wholly owned subsidiaries guarantee the notes. The indentures permit us to redeem the senior notes at any time at specified make-whole or redemption prices. The indentures contain covenants limiting our ability and our restricted subsidiaries’ ability to incur additional indebtedness; pay dividends on our capital stock or redeem, repurchase or retire our capital stock or subordinated indebtedness; make investments and other restricted payments; incur liens; engage in transactions with affiliates; sell assets; and consolidate, merge or transfer assets. The debt incurrence covenants do not presently restrict our ability to borrow under or expand our secured credit facility. As of June 30, 2005, we estimate that secured commercial bank indebtedness of approximately $2.1 billion could have been incurred under the most restrictive indenture covenant.

Results of Operations — Three Months Ended June 30, 2005 vs. June 30, 2004

General. For the Current Quarter, Chesapeake had net income of $193.8 million, or $0.52 per diluted common share, on total revenues of $1,048.0 million. This compares to net income of $97.2 million, or $0.30 per diluted common share, on total revenues of $574.3 million during the Prior Quarter. The Current Quarter net income includes, on a pre-tax basis, $84.2 million in net unrealized gains on oil and gas and interest rate derivatives and a $68.4 million loss on repurchases or exchanges of debt. The Prior Quarter net income included, on a pre-tax basis, $11.1 million in net unrealized losses on oil and gas and interest rate derivatives.

Oil and Gas Sales. During the Current Quarter, oil and gas sales were $772.4 million compared to $399.7 million in the Prior Quarter. In the Current Quarter, Chesapeake produced 113.2 bcfe at a weighted average price of $6.08 per mcfe, compared to 86.5 bcfe produced in the Prior Quarter at a weighted average price of $4.85 per mcfe (weighted average prices exclude the effect of unrealized gains or (losses) on derivatives of $84.1 million and ($20.2) million in the Current Quarter and Prior Quarter, respectively). In the Current Quarter, the increase in prices resulted in an increase in revenue of $139.2 million and increased production resulted in a $129.3 million increase, for a total increase in revenues of $268.5 million (excluding unrealized gains or losses on oil and gas derivatives). The increase in production from the Prior Quarter to the Current Quarter is due to the combination of production growth generated from drilling as well as acquisitions completed in 2004 and 2005.

The change in oil and gas prices has a significant impact on our oil and gas revenues and cash flows. Assuming the Current Quarter production levels, a change of $0.10 per mcf of gas sold would have resulted in an increase or decrease in revenues and cash flow of approximately $10.1 million and $9.4 million, respectively, and a change of $1.00 per barrel of oil sold would have resulted in an increase or decrease in revenues and cash flow of approximately $2.0 million and $1.9 million, respectively, without considering the effect of derivative activities.

For the Current Quarter, we realized an average price per barrel of oil of $42.82, compared to $28.12 in the Prior Quarter (weighted average prices for both quarters discussed exclude the effect of unrealized gains or losses on derivatives). Natural gas prices realized per mcf (excluding unrealized gains or losses on derivatives) were $5.95 and $4.87 in the Current Quarter and Prior Quarter, respectively. Realized gains or losses from our oil and gas derivatives resulted in a net decrease in oil and gas revenues of $44.4 million, or $0.39 per mcfe, in the Current Quarter and a net decrease of $55.3 million, or $0.64 per mcfe, in the Prior Quarter.

The following table shows our production by region for the Current Quarter and the Prior Quarter:

	For the Three Months Ended June 30,
	2005			2004
	Mmcfe	Percent		Mmcfe	Percent
Mid-Continent	74,569	66	%	64,064	74	%
South Texas and Texas Gulf Coast	16,142	14		10,494	12
Ark-La-Tex (including Barnett Shale)	12,491	11		3,307	4
Permian Basin	9,325	8		8,042	9
Other	673	1		641	1
Total Production	113,200	100	%	86,548	100	%

Natural gas production represented approximately 89% of our total production volume on an equivalent basis in the Current Quarter, compared to 88% in the Prior Quarter.

Oil and Gas Marketing Sales and Expenses. Chesapeake realized $275.6 million in oil and gas marketing sales to third parties in the Current Quarter, with corresponding oil and gas marketing expenses of $270.0 million, for a net margin of $5.6 million. Marketing activities are substantially for third parties that are owners in Chesapeake-operated wells. This compares to sales of $174.6 million, expenses of $171.1 million and a net margin of $3.5 million in the Prior Quarter. In the Current Quarter, Chesapeake realized an increase in oil and gas marketing sales volumes and an increase in oil and gas prices.

25

Production Expenses. Production expenses, which include lifting costs and ad valorem taxes, were $72.3 million in the Current Quarter compared to $49.6 million in the Prior Quarter. On a unit-of-production basis, production expenses were $0.64 per mcfe in the Current Quarter compared to $0.57 per mcfe in the Prior Quarter. The increase in the Current Quarter was primarily due to higher field service costs and ad valorem taxes on oil and gas properties. We expect that production expenses for the remainder of 2005 will range from $0.68 to $0.72 per mcfe produced.

Production Taxes. Production taxes were $47.3 million and $22.8 million in the Current Quarter and the Prior Quarter, respectively. On a unit-of-production basis, production taxes were $0.42 per mcfe in the Current Quarter compared to $0.26 per mcfe in the Prior Quarter. The $24.5 million increase in production taxes in the Current Quarter is due primarily to approximately 26.7 bcfe of increased production and the increase in sales prices (excluding gains or losses on derivatives). In general, production taxes are calculated using value-based formulas that produce higher per unit costs when oil and gas prices are higher. We expect production taxes for the remainder of 2005 to range from $0.43 to $0.48 per mcfe based on NYMEX prices of $50 per barrel of oil and natural gas wellhead prices ranging from $5.75 to $8.00 per mcf.

General and Administrative Expenses (excluding stock-based compensation). General and administrative expenses, which are net of internal payroll and non-payroll general and administrative costs capitalized in our oil and gas properties, were $9.3 million, or $0.08 per mcfe, in the Current Quarter and $7.4 million, or $0.09 per mcfe, in the Prior Quarter. The $1.9 million increase in the Current Quarter was the result of the company’s growth related to various acquisitions completed in the Current Period and in 2004 and the increase in drilling activity. This growth has resulted in a substantial increase in employees and related costs. We anticipate that general and administrative expenses for the remainder of 2005 will be between $0.10 and $0.12 per mcfe produced, which is approximately the same level as the Current Quarter.

Chesapeake follows the full-cost method of accounting under which all costs associated with property acquisition, exploration and development activities are capitalized. We capitalize internal costs that can be directly identified with our acquisition, exploration and development activities and do not include any costs related to production, general corporate overhead or similar activities. We capitalized $23.5 million and $12.4 million of internal costs in the Current Quarter and the Prior Quarter, respectively, directly related to our oil and gas exploration and development efforts.

Stock-Based Compensation. Stock-based compensation was $2.5 million in the Current Quarter and $0.7 million in the Prior Quarter. During the Current Quarter, a nominal number of shares of restricted stock were issued to employees. The cost of all outstanding restricted shares is amortized over a four-year period which resulted in the recognition of $4.1 million during the Current Quarter. Of this amount, $2.2 million was reflected as stock-based compensation expense (a sub-category of general and administrative expenses) in the condensed consolidated statements of operations, and the remaining $1.9 million was capitalized to oil and gas properties. We also recognized $0.3 million in stock-based compensation expense in the Current Quarter as a result of modifications made to previously issued stock options. Stock-based compensation was $0.02 per mcfe for the Current Quarter and $0.01 per mcfe for the Prior Quarter. We anticipate that stock-based compensation expense for the remainder of 2005 will be between $0.03 and $0.05 per mcfe produced.

Oil and Gas Depreciation, Depletion and Amortization. Depreciation, depletion and amortization of oil and gas properties was $209.4 million and $136.7 million during the Current Quarter and the Prior Quarter, respectively. The average DD&A rate per mcfe, which is a function of capitalized costs, future development costs and the related underlying reserves in the periods presented, was $1.85 and $1.58 in the Current Quarter and in the Prior Quarter, respectively. The $0.27 increase in the average DD&A rate is primarily the result of higher drilling costs and higher costs associated with acquisitions, including the recognition of the tax effect of acquisition costs in excess of tax basis acquired in certain corporate acquisitions. We expect the DD&A rate for the remainder of 2005 to be between $1.85 and $1.95 per mcfe produced.

Depreciation and Amortization of Other Assets. Depreciation and amortization of other assets was $11.8 million in the Current Quarter compared to $6.7 million in the Prior Quarter. The increase in the Current Quarter was primarily the result of higher depreciation costs resulting from the acquisition of various gathering facilities, construction of new buildings at our corporate headquarters and the purchase of additional information technology equipment in 2004 and the Current Quarter. Property and equipment costs are depreciated on a straight-line basis.

26

Buildings are depreciated over 39 years, drilling rigs are depreciated over 15 years and all other property and equipment are depreciated over the estimated useful lives of the assets, which range from two to fifteen years. To the extent drilling rigs are used to drill our wells, the depreciation is capitalized in oil and gas properties as exploration or development costs. We expect depreciation and amortization of other assets for the remainder of 2005 to be between $0.09 and $0.11 per mcfe produced.

Interest and Other Income. Interest and other income was $2.0 million in the Current Quarter compared to $1.3 million in the Prior Quarter. The Current Quarter income consisted of $0.4 million of interest income, $1.1 million related to earnings of equity investees and $0.5 million of miscellaneous income. The Prior Quarter income consisted of $0.5 million of interest income, $0.6 million related to earnings of equity investees and $0.2 million of miscellaneous income.

Interest Expense. Interest expense increased from $28.8 million in the Prior Quarter to $53.9 million in the Current Quarter as follows:

	Three Months Ended June 30,
	2005			2004
	($ in millions)
Interest expense on senior notes and revolving bank credit facility	$	71.2		$	43.8
Capitalized interest		(17.9	)		(7.4	)
Amortization of loan discount		1.4			1.1
Unrealized (gain) loss on interest rate derivatives		(0.1	)		(9.1	)
Realized (gain) loss on interest rate derivatives		(0.7	)		0.4
Total interest expense	$	53.9		$	28.8
Average long-term borrowings	$	3,554		$	2,240

The $27.4 million increase in interest expense on senior notes ($21.7 million increase) and revolving bank credit facility ($5.7 million increase) is due to a higher average balance of senior notes outstanding, $3.6 billion in the Current Quarter compared to $2.2 billion in the Prior Quarter, partially offset by a decrease in the average interest rate, 7.2% in the Current Quarter compared to 7.7% in the Prior Quarter. The increase in the credit facility interest expense is the result of higher borrowings and an increase in interest rates.

The $10.5 million increase in capitalized interest is the direct result of interest capitalized on our additional investments in unevaluated properties acquired since the Prior Quarter. Interest is capitalized on significant investments in unevaluated properties that are not being currently depreciated, depleted or amortized and on which exploration activities are in progress.

Interest expense, excluding unrealized gains or losses on derivatives, was $0.48 per mcfe in the Current Quarter compared to $0.44 per mcfe in the Prior Quarter. We expect interest expense (before considering the effect of interest rate derivatives) for the remainder of 2005 to be between $0.45 and $0.49 per mcfe produced.

Loss on Repurchases or Exchanges of Chesapeake Debt. We repurchased or exchanged Chesapeake debt in the Current Quarter and incurred losses in connection with these transactions. The following table shows the losses related to these transactions ($ in millions):

	Notes Retired		Loss on Repurchases/Exchanges
			Premium		Other(a)		Total
For the Three Months Ended June 30, 2005:
8.125% Senior Notes due 2011	$	237.8	$	16.8	$	4.3	$	21.1
9.0% Senior Notes due 2012		298.9		41.3		6.0		47.3
	$	536.7	$	58.1	$	10.3	$	68.4

(a) Includes write-offs of discounts, deferred charges and interest rate derivatives associated with notes retired and transaction costs.

There were no losses on repurchases or exchanges of Chesapeake debt in the Prior Quarter.

Income Tax Expense. Chesapeake recorded income tax expense of $111.4 million in the Current Quarter, compared to income tax expense of $54.7 million in the Prior Quarter. Our effective income tax rate increased to 36.5% in the Current Quarter compared to 36% in the Prior Quarter. The increase in the Current Quarter reflected the impact state income taxes and permanent differences had on our overall effective rate. All 2004 income tax expense was deferred, and we expect most, if not all, of our 2005 income tax expense to be deferred.

27

Results of Operations — Six Months Ended June 30, 2005 vs. June 30, 2004

General. For the Current Period, Chesapeake had net income of $318.8 million, or $0.88 per diluted common share, on total revenues of $1,831.5 million. This compares to net income of $209.7 million, or $0.67 per diluted common share, on total revenues of $1,137.4 million during the Prior Period. The Current Period net income includes, on a pre-tax basis, $29.9 million in net unrealized losses on oil and gas and interest rate derivatives and a $69.3 million loss on repurchases or exchanges of debt. The Prior Period net income included, on a pre-tax basis, $33.8 million in net unrealized losses on oil and gas and interest rate derivatives and a $6.9 million loss on repurchases or exchanges of debt.

Oil and Gas Sales. During the Current Period, oil and gas sales were $1,311.3 million compared to $819.5 million in the Prior Period. In the Current Period, Chesapeake produced 217.8 bcfe at a weighted average price of $6.17 per mcfe, compared to 165.4 bcfe produced in the Prior Period at a weighted average price of $5.16 per mcfe (weighted average prices exclude the effect of unrealized gains or (losses) on derivatives of ($33.1) million and ($34.2) million in the Current Period and Prior Period, respectively). In the Current Period, the increase in prices resulted in an increase in revenue of $220.0 million and increased production resulted in a $270.8 million increase, for a total increase in revenues of $490.8 million (excluding unrealized gains or losses on oil and gas derivatives). The increase in production from the Prior Period to the Current Period is due to the combination of production growth generated from drilling as well as acquisitions completed in 2004 and 2005.

The change in oil and gas prices has a significant impact on our oil and gas revenues and cash flows. Assuming the Current Period production levels, a change of $0.10 per mcf of gas sold would have resulted in an increase or decrease in revenues and cash flow of approximately $19.5 million and $18.3 million, respectively, and a change of $1.00 per barrel of oil sold would have resulted in an increase or decrease in revenues and cash flow of approximately $3.8 million and $3.5 million, respectively, without considering the effect of derivative activities.

For the Current Period, we realized an average price per barrel of oil of $42.32, compared to $27.65 in the Prior Period (weighted average prices for both periods discussed exclude the effect of unrealized gains or losses on derivatives). Natural gas prices realized per mcf (excluding unrealized gains or losses on derivatives) were $6.07 and $5.23 in the Current Period and Prior Period, respectively. Realized gains or losses from our oil and gas derivatives resulted in a net decrease in oil and gas revenues of $4.0 million, or $0.02 per mcfe, in the Current Period and a net decrease of $29.7 million, or $0.18 per mcfe, in the Prior Period.

The following table shows our production by region for the Current Period and the Prior Period:

	For the Six Months Ended June 30,
	2005			2004
	Mmcfe	Percent		Mmcfe	Percent
Mid-Continent	147,381	67	%	126,640	77	%
South Texas and Texas Gulf Coast	28,078	13		18,728	11
Ark-La-Tex (including Barnett Shale)	23,914	11		5,299	3
Permian Basin	17,112	8		13,463	8
Other	1,322	1		1,306	1
Total Production	217,807	100	%	165,436	100	%

Natural gas production represented approximately 90% of our total production volume on an equivalent basis in the Current Period, compared to 89% in the Prior Period.

Oil and Gas Marketing Sales and Expenses. Chesapeake realized $520.1 million in oil and gas marketing sales to third parties in the Current Period, with corresponding oil and gas marketing expenses of $507.3 million, for a net margin of $12.8 million. Marketing activities are substantially for third parties that are owners in Chesapeake- operated wells. This compares to sales of $318.0 million, expenses of $310.8 million and a net margin of $7.2 million in the Prior Period. In the Current Period, Chesapeake realized an increase in oil and gas marketing sales volumes and an increase in oil and gas prices.

Production Expenses. Production expenses, which include lifting costs and ad valorem taxes, were $141.9 million in the Current Period compared to $94.4 million in the Prior Period. On a unit-of-production basis, production expenses were $0.65 per mcfe in the Current Period compared to $0.57 per mcfe in the Prior Period. The increase in the Current Period was primarily due to higher field service costs and ad valorem taxes on oil and gas properties. We expect that production expenses for the remainder of 2005 will range from $0.68 to $0.72 per mcfe.

28

Production Taxes. Production taxes were $83.2 million and $37.7 million in the Current Period and the Prior Period, respectively. On a unit-of-production basis, production taxes were $0.38 per mcfe in the Current Period compared to $0.23 per mcfe in the Prior Period. The $45.5 million increase in production taxes in the Current Period is due primarily to approximately 52.4 bcfe of increased production and the increase in sales price (excluding gains or losses on derivatives). Also included in the Prior Period was a credit of $6.8 million, or $0.04 per mcfe, related to certain Oklahoma severance tax abatements for the period July 2003 through December 2003. In April 2004, the Oklahoma Tax Commission concluded that a pre-determined oil and gas price cap for 2003 sales had not been exceeded (on a statewide basis) and notified the company that it was eligible to receive certain severance tax abatements for the period from July 1, 2003 through June 30, 2004. The company had previously estimated that the average oil and gas sales prices in Oklahoma (on a statewide basis) could exceed the price cap, and did not reflect the benefit from these potential severance tax abatements until the first quarter of 2004. In general, production taxes are calculated using value-based formulas that produce higher per unit costs when oil and gas prices are higher. We expect production taxes for the remainder of 2005 will range from $0.43 to $0.48 per mcfe based on NYMEX prices of $50 per barrel of oil and natural gas wellhead prices ranging from $5.75 to $8.00 per mcf.

General and Administrative Expenses (excluding stock-based compensation). General and administrative expenses, which are net of internal payroll and non-payroll general and administrative costs capitalized in our oil and gas properties, were $18.9 million, or $0.09 per mcfe, in the Current Period and $15.6 million, or $0.09 per mcfe, in the Prior Period. The $3.3 million increase in the Current Period was the result of the company’s growth related to various acquisitions completed in the Current Period and in 2004 and the increase in drilling activity. This growth has resulted in a substantial increase in employees and related costs. We anticipate that general and administrative expenses for the remainder of 2005 will be between $0.10 and $0.12 per mcfe produced, which is approximately the same level as the Current Period.

Chesapeake follows the full-cost method of accounting under which all costs associated with property acquisition, exploration and development activities are capitalized. We capitalize internal costs that can be directly identified with our acquisition, exploration and development activities and do not include any costs related to production, general corporate overhead or similar activities. We capitalized $45.8 million and $23.3 million of internal costs in the Current Period and the Prior Period, respectively, directly related to our oil and gas exploration and development efforts.

Stock-Based Compensation. Stock-based compensation was $4.9 million in the Current Period and $2.5 million in the Prior Period. During the Current Period, 1.8 million shares of restricted stock were issued to employees. The cost of all outstanding restricted shares is amortized over a four-year period which resulted in the recognition of $8.1 million during the Current Period. Of this amount, $4.4 million was reflected as stock-based compensation expense (a sub-category of general and administrative expenses) in the condensed consolidated statements of operations, and the remaining $3.7 million was capitalized to oil and gas properties. We also recognized $0.4 million in stock-based compensation expense in the Current Period as a result of modifications made to previously issued stock options and an additional $0.1 million related to the issuance of common stock to a director. Stock-based compensation was $0.02 per mcfe for the Current Period and $0.02 per mcfe for the Prior Period. We anticipate that stock-based compensation expense for the remainder of 2005 will be between $0.03 and $0.05 per mcfe produced.

Oil and Gas Depreciation, Depletion and Amortization. Depreciation, depletion and amortization of oil and gas properties was $390.3 million and $256.7 million during the Current Period and the Prior Period, respectively. The average DD&A rate per mcfe, which is a function of capitalized costs, future development costs and the related underlying reserves in the periods presented, was $1.79 and $1.55 in the Current Period and in the Prior Period, respectively. The $0.24 increase in the average DD&A rate is primarily the result of higher drilling costs and higher costs associated with acquisitions, including the recognition of the tax effect of acquisition costs in excess of tax basis acquired in certain corporate acquisitions. We expect the DD&A rate for the remainder of 2005 to be between $1.85 and $1.95 per mcfe produced.

Depreciation and Amortization of Other Assets. Depreciation and amortization of other assets was $21.9 million in the Current Period compared to $12.5 million in the Prior Period. The increase in the Current Period was primarily the result of higher depreciation costs resulting from the acquisition of various gathering facilities, construction of new buildings at our corporate headquarters and the purchase of additional information technology equipment in 2004 and the Current Period. Property and equipment costs are depreciated on a straight-line basis. Buildings are depreciated over 39 years, drilling rigs are depreciated over 15 years and all other property and equipment are depreciated over the estimated useful lives of the assets, which range from two to fifteen years. To the extent drilling rigs are used to drill our wells, the depreciation is capitalized in oil and gas properties as exploration or development costs. We expect depreciation and amortization of other assets for the remainder of 2005 to be between $0.09 and $0.11 per mcfe produced.

Interest and Other Income. Interest and other income was $5.4 million in the Current Period compared to $2.7 million in the Prior Period. The Current Period income consisted of $3.1 million of interest income, $1.2 million related to earnings of equity investees and $1.1 million of miscellaneous income. The Prior Period income consisted of $0.9 million of interest income, $1.1 million related to earnings of equity investees and $0.7 million of miscellaneous income.

Interest Expense. Interest expense increased from $75.4 million in the Prior Period to $97.0 million in the Current Period as follows:

	Six Months Ended June 30,
	2005			2004
	($ in millions)
Interest expense on senior notes and revolving bank credit facility	$	133.1		$	86.7
Capitalized interest		(33.9	)		(12.7	)
Amortization of loan discount		2.8			2.1
Unrealized gain on interest rate derivatives		(3.2	)		(0.3	)
Realized gain on interest rate derivatives		(1.8	)		(0.4	)
Total interest expense	$	97.0		$	75.4
Average long-term borrowings	$	3,356		$	2,188

The $46.4 million increase in interest expense on senior notes ($37.1 million increase) and revolving bank credit facility ($9.3 million increase) is due to a higher average balance of senior notes outstanding, $3.4 billion in the Current Period compared to $2.2 billion in the Prior Period, partially offset by a decrease in the average interest rate, 7.2% in the Current Period compared to 7.8% in the Prior Period. The increase in the credit facility interest expense is the result of higher borrowings and an increase in interest rates.

The $21.2 million increase in capitalized interest is the direct result of interest capitalized on our additional investments in unevaluated properties acquired since the Prior Period. Interest is capitalized on significant investments in unevaluated properties that are not being currently depreciated, depleted or amortized and on which exploration activities are in progress.

Interest expense, excluding unrealized gains or losses on derivatives, was $0.46 per mcfe in the Current Period and Prior Period. We expect interest expense (before considering the effect of interest rate derivatives) for the remainder of 2005 to be between $0.45 and $0.49 per mcfe produced.

Loss on Repurchases or Exchanges of Chesapeake Debt. We have repurchased or exchanged Chesapeake debt and incurred losses in connection with these transactions. The following table shows the losses related to these transactions ($ in millions):

	Notes Retired		Loss on Repurchases/Exchanges

(a) Includes write-offs of discounts, deferred charges and interest rate derivatives associated with notes retired and transaction costs.

Income Tax Expense. Chesapeake recorded income tax expense of $183.2 million in the Current Period, compared to income tax expense of $118.0 million in the Prior Period. Our effective income tax rate increased to 36.5% in the Current Period compared to 36% in the Prior Period. The increase in the Current Period reflected the impact state income taxes and permanent differences had on our overall effective rate. All 2004 income tax expense was deferred, and we expect most, if not all, of our 2005 income tax expense to be deferred.

Critical Accounting Policies

We consider accounting policies related to hedging, oil and gas properties, income taxes and business combinations to be critical policies. These policies are summarized in Management’s Discussion and Analysis of Financial Condition and Results of Operations in our annual report on Form 10-K for the year ended December 31, 2004.

Recently Issued Accounting Standards

The Financial Accounting Standards Board and the Securities and Exchange Commission recently issued the following standards which were reviewed by Chesapeake to determine the potential impact on our financial statements upon adoption.

In December 2004, the Financial Accounting Standards Board issued SFAS 123(R), Share-Based Payment, a revision of SFAS 123, accounting for stock-based compensation. This statement establishes standards for the accounting for transactions in which an entity exchanges its equity instruments for goods or services by requiring a public entity to measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. This statement is effective as of the beginning of the annual reporting period that begins after June 15, 2005.

Chesapeake will implement SFAS 123(R) in the first quarter of 2006 and the Black-Scholes option pricing model will be used to value the stock options as of the grant date. Based on the stock options outstanding and unvested at June 30, 2005 and our current intention to limit future awards of stock options, we do not believe the new accounting requirement will have a significant impact on future results of operations.

In March 2005, the FASB issued FASB Interpretation No. (FIN) 47, Accounting for Conditional Asset Retirement Obligations. FIN 47 specifies the accounting treatment for conditional asset retirement obligations under the provisions of Statement of Financial Accounting Standards No. 143. FIN 47 is effective no later than the end of the fiscal year ending after December 15, 2005. Implementation of FIN 47 is not expected to have a material effect on our financial statements.

Forward-Looking Statements

This report includes “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Forward-looking statements give our current expectations or forecasts of future events. They include statements regarding oil and gas reserve estimates, planned capital expenditures, the drilling of oil and gas wells and future acquisitions, expected oil and gas production, cash flow and anticipated liquidity, business strategy and other plans and objectives for future operations and expected future expenses. Statements concerning the fair values of derivative contracts and their estimated contribution to our future results of operations are based upon market information as of a specific date. These market prices are subject to significant volatility.

Although we believe the expectations and forecasts reflected in these and other forward-looking statements are reasonable, we can give no assurance they will prove to have been correct. They can be affected by inaccurate assumptions or by known or unknown risks and uncertainties. Factors that could cause actual results to differ materially from expected results are described under “Risk Factors” in Item 1 of our annual report on Form 10-K for the year ended December 31, 2004 and include:

• the volatility of oil and gas prices,

• our level of indebtedness,

• the strength and financial resources of our competitors,

• the availability of capital on an economic basis to fund reserve replacement costs,

• uncertainties inherent in estimating quantities of oil and gas reserves and projecting future rates of production and the timing of development expenditures,

31

• our ability to replace reserves and sustain production,

• uncertainties in evaluating oil and gas reserves of acquired properties and associated potential liabilities,

• unsuccessful exploration and development drilling,

• declines in the value of our oil and gas properties resulting in ceiling test write-downs,

• lower prices realized on oil and gas sales and collateral required to secure hedging liabilities resulting from our commodity price risk management activities and

• drilling and operating risks.

We caution you not to place undue reliance on these forward-looking statements, which speak only as of the date of this report, and we undertake no obligation to update this information. We urge you to carefully review and consider the disclosures made in this report and our other filings with the Securities and Exchange Commission that attempt to advise interested parties of the risks and factors that may affect our business.

ITEM 3. Quantitative and Qualitative Disclosures About Market Risk

Oil and Gas Hedging Activities

Our results of operations and operating cash flows are impacted by changes in market prices for oil and gas. To mitigate a portion of the exposure to adverse market changes, we have entered into various derivative instruments. As of June 30, 2005, our oil and gas derivative instruments were comprised of swaps, cap-swaps, basis protection swaps, call options and collars. These instruments allow us to predict with greater certainty the effective oil and gas prices to be received for our hedged production. Although derivatives often fail to achieve 100% effectiveness for accounting purposes, we believe our derivative instruments continue to be highly effective in achieving the risk management objectives for which they were intended.

• For swap instruments, Chesapeake receives a fixed price for the hedged commodity and pays a floating market price to the counterparty. The fixed-price payment and the floating-price payment are netted, resulting in a net amount due to or from the counterparty.

• For cap-swaps, Chesapeake receives a fixed price and pays a floating market price. The fixed price received by Chesapeake includes a premium in exchange for a “cap” limiting the counterparty’s exposure. In other words, there is no limit to Chesapeake’s exposure but there is a limit to the downside exposure of the counterparty.

• Basis protection swaps are arrangements that guarantee a price differential for oil or gas from a specified delivery point. Chesapeake receives a payment from the counterparty if the price differential is greater than the stated terms of the contract and pays the counterparty if the price differential is less than the stated terms of the contract.

• For call options, Chesapeake receives a cash premium from the counterparty in exchange for the sale of a call option. If the market price exceeds the fixed price of the call option, then Chesapeake pays the counterparty such excess. If the market price settles below the fixed price of the call option, no payment is due from Chesapeake.

• Collars contain a fixed floor price (put) and ceiling price (call). If the market price exceeds the call strike price or falls below the put strike price, Chesapeake receives the fixed price and pays the market price. If the market price is between the call and the put strike price, no payments are due from either party.

Chesapeake enters into counter-swaps from time to time for the purpose of locking-in the value of a swap. Under the counter-swap, Chesapeake receives a floating price for the hedged commodity and pays a fixed price to the counterparty. The counter-swap is 100% effective in locking-in the value of a swap since subsequent changes in the market value of the swap are entirely offset by subsequent changes in the market value of the counter-swap. We refer to this locked-in value as a locked swap. At the time Chesapeake enters into a counter-swap, Chesapeake removes the original swap’s designation as a cash flow hedge and classifies the original swap as a non-qualifying

32

hedge under SFAS 133. The reason for this new designation is that collectively the swap and the counter-swap no longer hedge the exposure to variability in expected future cash flows. Instead, the swap and counter-swap effectively lock-in a specific gain (or loss) that will be unaffected by subsequent variability in oil and gas prices. Any locked-in gain or loss is recorded in accumulated other comprehensive income and reclassified to oil and gas sales in the month of related production.

With respect to counter-swaps that are designed to lock-in the value of cap-swaps, the counter-swap is effective in locking-in the value of the cap-swap until the floating price reaches the cap (or floor) stipulated in the cap-swap agreement. The value of the counter-swap will increase (or decrease), but in the opposite direction, as the value of the cap-swap decreases (or increases) until the floating price reaches the pre-determined cap (or floor) stipulated in the cap-swap agreement. However, because of the written put option embedded in the cap-swap, the changes in value of the cap-swap are not completely effective in offsetting changes in value of the corresponding counter-swap. Changes in the value of cap-swaps and the counter-swaps are recorded as adjustments to oil and gas sales.

In accordance with FASB Interpretation No. 39, to the extent that a legal right of setoff exists, Chesapeake nets the value of its derivative arrangements with the same counterparty in the accompanying condensed consolidated balance sheets.

Chesapeake enters into basis protection swaps for the purpose of locking-in a price differential for oil or gas from a specified delivery point. We currently have basis protection swaps covering four different delivery points which correspond to the actual prices we receive for much of our gas production. By entering into these basis protection swaps, we have effectively reduced our exposure to market changes in future gas price differentials. As of June 30, 2005, the fair value of our basis protection swaps was $128.1 million. As of June 30, 2005, our basis protection swaps cover approximately 44% of our anticipated gas production remaining in 2005, 28% in 2006, 25% in 2007, 22% in 2008 and 16% in 2009.

Gains or losses from derivative transactions are reflected as adjustments to oil and gas sales on the condensed consolidated statements of operations. Realized gains (losses) included in oil and gas sales were ($44.4) million, ($55.3) million, ($4.0) million and ($29.7) million in the Current Quarter, Prior Quarter, Current Period and Prior Period, respectively. Pursuant to SFAS 133, certain derivatives do not qualify for designation as cash flow hedges. Changes in the fair value of these non-qualifying derivatives that occur prior to their maturity (i.e., temporary fluctuations in value) are reported currently in the consolidated statements of operations as unrealized gains (losses) within oil and gas sales. Unrealized gains (losses) included in oil and gas sales were $84.1 million, ($20.2) million, ($33.1) million and ($34.2) million, in the Current Quarter, Prior Quarter, Current Period and Prior Period, respectively.

Following provisions of SFAS 133, changes in the fair value of derivative instruments designated as cash flow hedges, to the extent they are effective in offsetting cash flows attributable to the hedged risk, are recorded in other comprehensive income until the hedged item is recognized in earnings. Any change in fair value resulting from ineffectiveness is recognized currently in oil and gas sales as unrealized gains (losses). We recorded a gain (loss) on ineffectiveness of $1.2 million, ($8.0) million, $0.6 million and ($15.2) million in the Current Quarter, Prior Quarter, Current Period and Prior Period, respectively.

As of June 30, 2005, we had the following open oil and gas derivative instruments designed to hedge a portion of our oil and gas production for periods after June 2005:

We have established the fair value of all derivative instruments using estimates of fair value reported by our counterparties and subsequently evaluated internally using established index prices and other sources. The actual contribution to our future results of operations will be based on the market prices at the time of settlement and may be more or less than the fair value estimates used at June 30, 2005.

Based upon the market prices at June 30, 2005, we expect to transfer approximately $51.5 million (net of income taxes) of the loss included in the balance in accumulated other comprehensive income to earnings during the next 12 months when the transactions actually occur. All transactions hedged as of June 30, 2005 are expected to mature by December 31, 2007, with the exception of our basis protection swaps which extend through 2009.

34

Additional information concerning the fair value of our oil and gas derivative instruments is as follows:

	2005
	($ in thousands)
Fair value of contracts outstanding, as of January 1	$	38,350
Change in fair value of contracts during the period		(160,532	)
Contracts realized or otherwise settled during the period		4,005
Fair value of contracts outstanding, as of June 30	$	(118,177	)

The change in the fair value of our derivative instruments since January 1, 2005 resulted from the settlement of derivatives for a realized gain as well as an increase in oil and natural gas prices. Derivative instruments reflected as current in the condensed consolidated balance sheet represent the estimated fair value of derivative instrument settlements scheduled to occur over the subsequent twelve-month period based on market prices for oil and gas as of the condensed consolidated balance sheet date. The derivative settlement amounts are not due and payable until the month in which the related underlying hedged transaction occurs.

Interest Rate Risk

The table below presents principal cash flows and related weighted average interest rates by expected maturity dates. As of June 30, 2005, the fair value of the fixed-rate long-term debt has been estimated based on quoted market prices.

	Years of Maturity
	2005		2006		2007		2008			2009		Thereafter			Total			Fair Value
Liabilities:
Long-term debt — fixed-rate(a)	$	—	$	—	$	—	$	8.0		$	—	$	3,743.4		$	3,751.4		$	3,865.7
Average interest rate		—		—		—		8.4	%		—		6.9	%		6.9	%		6.9	%
Long-term debt — variable rate	$	—	$	—	$	—	$	—		$	—	$	455.0		$	455.0		$	455.0
Average interest rate		—		—		—		—			—		4.6	%		4.6	%		4.6	%

(a) This amount does not include the discount included in long-term debt of ($87.3) million and the premium for interest rate swaps of $6.8 million.

Changes in interest rates affect the amount of interest we earn on our cash, cash equivalents and short-term investments and the interest rate we pay on borrowings under our revolving bank credit facility. All of our other long-term indebtedness is fixed rate and therefore does not expose us to the risk of earnings or cash flow loss due to changes in market interest rates. However, changes in interest rates do affect the fair value of our debt.

Interest Rate Derivatives

We use interest rate derivatives to mitigate our exposure to the volatility in interest rates. For interest rate derivative instruments designated as fair value hedges (in accordance with SFAS 133), changes in fair value of interest rate derivatives are recorded on the consolidated balance sheets as assets (liabilities) and the debt’s carrying value amount is adjusted by the change in the fair value of the debt subsequent to the initiation of the derivative. Any resulting differences are recorded currently as ineffectiveness in the consolidated statements of operations as an adjustment to interest expense. Changes in the fair value of derivative instruments not qualifying as fair value hedges are recorded currently as adjustments to interest expense.

As of June 30, 2005, the following interest rate swap was used to convert a portion of our long-term fixed-rate debt to floating-rate debt was outstanding:

Term	Notional Amount		Fixed Rate		Floating Rate	Fair Value Gain (Loss)
						($ in thousands)
September 2004 – August 2012	$	75,000,000	9.000	%	6 month LIBOR plus 452 basis points	$	(714	)

Subsequent to June 30, 2005, we entered into the following interest rate swaps (which qualify as fair value hedges) to convert a portion of our long-term fixed-rate debt to floating-rate debt:

Term	Notional Amount		Fixed Rate		Floating Rate
July 2005 – January 2015	$	150,000,000	7.750	%	6 month LIBOR plus 289 basis points
July 2005 – June 2014	$	150,000,000	7.500	%	6 month LIBOR plus 282 basis points
August 2005 – August 2014	$	200,000,000	7.000	%	6 month LIBOR plus 205.5 basis points

35

In the Current Quarter and Current Period, we closed various interest rate swaps for gains totaling $4.3 million and $5.1 million, respectively. These interest rate swaps were designated as fair value hedges, and the settlement amounts received will be amortized as a reduction to realized interest expense over the remaining terms of the related senior notes.

In March 2004, Chesapeake entered into an interest rate swap which required Chesapeake to pay a fixed rate of 8.68% while the counterparty paid Chesapeake a floating rate of six month LIBOR plus 0.75% on a notional amount of $142.7 million. On March 15, 2005, we elected to terminate the interest rate swap and paid $31.8 million to the counterparty.

ITEM 4. Controls and Procedures

We maintain disclosure controls and procedures designed to ensure that information required to be disclosed by Chesapeake in reports filed or submitted by it under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission rules and forms. At the end of the period covered by this report, we carried out an evaluation, under the supervision and with the participation of Chesapeake management, including Chesapeake’s Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of Chesapeake’s disclosure controls and procedures pursuant to Securities Exchange Act Rule 13a-15(b). Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures are effective.

No changes in Chesapeake’s internal control over financial reporting occurred during the Current Quarter that have materially affected, or are reasonably likely to materially affect, Chesapeake’s internal control over financial reporting.

Dividends payable for any partial dividend period shall be computed on the basis of days elapsed over a 360-day year consisting of twelve 30-day months. Accumulations of dividends on shares of Preferred Stock shall not bear interest.

(2) If (i) by May 5, 2003, the Shelf Registration Statement has not been filed with the Commission, (ii) by September 1, 2003, the Shelf Registration Statement has not been declared effective by the Commission or (iii) after the Shelf Registration Statement has been declared effective, (A) the Shelf Registration Statement thereafter ceases to be effective or (B) the Shelf Registration Statement or the related prospectus ceases to be usable (in each case, subject to the exceptions described below) in connection with resales of Transfer Restricted Securities during the period that any Transfer Restricted Securities remain outstanding (each such event referred to in clauses (i), (ii) and (iii), a “Registration Default”), additional dividends shall accrue on the Preferred Stock at the rate of .50% per annum (resulting in a Dividend Rate of 6.50% per annum during the continuance of a Registration Default), from and including the date on which any such Registration Default shall occur to but excluding the date on which all Registration Defaults have been cured. At all other times, dividends shall accumulate on the Preferred Stock at the Dividend Rate as described in Section 3(a).

A Registration Default referred to in clause (iii) of Section 3(b) shall be deemed not to have occurred and be continuing in relation to the Shelf Registration Statement or the related prospectus if (i) such Registration Default has occurred solely as a result of (x) the filing of a post-effective amendment to the Shelf Registration Statement to incorporate annual audited financial information with respect to the Company where such post-effective amendment is not yet effective and needs to be declared effective to permit Holders to use the related prospectus or (y) other material events, with respect to the Company that would need to be described in the Shelf Registration Statement or the related prospectus and (ii) in the case of clause (y), the Company is proceeding promptly and in good faith to amend or supplement such Shelf Registration Statement and related prospectus to describe such events; provided, however, that in any case if such Registration Default referred to in clause (iii) of Section 3(b) occurs for a continuous period in excess of 30 days, additional dividends as described in Section 3(b) shall be payable in accordance therewith from the day such Registration Default occurs until such Registration Default is cured.

(3) No dividend will be declared or paid upon, or any sum set apart for the payment of dividends upon, any outstanding share of the Preferred Stock with respect to any dividend period unless all dividends for all preceding dividend periods have been declared and paid or declared and a sufficient sum set apart for the payment of such dividend, upon all outstanding shares of Preferred Stock.

(4) No dividends or other distributions (other than a dividend or distribution payable solely in shares of Parity Stock or Junior Stock (in the case of Parity Stock) or Junior Stock (in the case of Junior Stock) and other than cash paid in lieu of fractional shares) may be declared, made or paid, or set apart for payment upon, any Parity Stock or Junior Stock, nor may any Parity Stock or Junior Stock be redeemed, purchased or otherwise acquired for any consideration (or any money paid to or made

7

available for a sinking fund for the redemption of any Parity Stock or Junior Stock) by or on behalf of the Company (except by conversion into or exchange for shares of Parity Stock or Junior Stock (in the case of Parity Stock) or Junior Stock (in the case of Junior Stock)), unless full Accumulated Dividends shall have been or contemporaneously are declared and paid, or are declared and a sum sufficient for the payment thereof is set apart for such payment, on the Preferred Stock and any Parity Stock for all dividend payment periods terminating on or prior to the date of such declaration, payment, redemption, purchase or acquisition. Notwithstanding the foregoing, if full dividends have not been paid on the Preferred Stock and any Parity Stock, dividends may be declared and paid on the Preferred Stock and such Parity Stock so long as the dividends are declared and paid pro rata so that the amounts of dividends declared per share on the Preferred Stock and such Parity Stock will in all cases bear to each other the same ratio that accumulated and unpaid dividends per share on the shares of Preferred Stock and such other Parity Stock bear to each other.

(5) Holders of shares of Preferred Stock shall not be entitled to any dividends on the Preferred Stock, whether payable in cash, property or stock, in excess of full cumulative dividends. No interest, or sum of money in lieu of interest, shall be payable in respect of any dividend payment or payments on the Preferred Stock which may be in arrears.

(6) The holders of shares of Preferred Stock at the close of business on a Dividend Record Date will be entitled to receive the dividend payment on those shares on the corresponding Dividend Payment Date notwithstanding the subsequent conversion thereof or the Company’s default in payment of the dividend due on that Dividend Payment Date. However, shares of Preferred Stock surrendered for conversion during the period between the close of business on any Dividend Record Date and the close of business on the Business Day immediately preceding the applicable Dividend Payment Date must be accompanied by payment of an amount equal to the dividend payable on the shares on that Dividend Payment Date. A holder of shares of Preferred Stock on a Dividend Record Date who (or whose transferee) tenders any shares for conversion on the corresponding Dividend Payment Date will receive the dividend payable by the Company on the Preferred Stock on that date, and the converting holder need not include payment in the amount of such dividend upon surrender of shares of Preferred Stock for conversion. Except as provided above with respect to a voluntary conversion pursuant to Section 7, the Company shall make no payment or allowance for unpaid dividends, whether or not in arrears, on converted shares or for dividends on the shares of Common Stock issued upon conversion.

4. Change of Control.

(1) Upon the occurrence of a Change of Control, each holder of Preferred Stock shall, in the event that the Market Value for the period ending on the Change of Control Date is less than the Conversion Price, have a one-time option (the “Change of Control Option”) to convert all of such holder’s outstanding shares of Preferred Stock into fully paid and nonassessable shares of Common Stock at an adjusted Conversion Price equal to the greater of (i) the Market Value for the period ending on the Change of Control Date and (ii) $5.47. The Change of Control Option must be exercised, if at all, during the period of not less than 30 days nor more than 60 days commencing on the third Business Day after notice of a Change in Control has been given by the Company in accordance with Section 4(b). In lieu of issuing the shares of Common Stock issuable upon conversion in the event of a Change of Control, the Company may, at its option, make a cash payment equal to the Market Value for each share of such Common Stock otherwise issuable determined for the period ending on the Change of Control Date. Notwithstanding the foregoing, upon the occurrence of a Change of Control in which (i) each holder of Common Stock receives consideration consisting solely of common stock of the successor, acquiror or other third party (and cash paid in lieu of fractional shares) that is listed on a national securities exchange or quoted on the NASDAQ National Market and (ii) all the Common Stock has been exchanged for, converted into or acquired for common stock of the successor, acquiror or other third party (and cash in lieu of factional shares), and the Preferred Stock becomes convertible solely into such common stock, the Conversion Price will not be adjusted as described in this Section 4(a).

(2) In the event of a Change of Control (other than a Change of Control described in the last sentence of Section 4(a)), notice of such Change of Control shall be given, within five Business Days of the Change of Control Date, by the Company by first-class mail to each record holder of shares of Preferred Stock, at such holder’s address as the same appears on the books of the Company. Each such notice shall state (i) that a Change of Control has occurred; (ii) the last day on which the Change of Control Option may be exercised (the “Expiration Date”) pursuant to the terms hereof; (iii) the name and address of the Transfer Agent; and (iv) the procedures that holders must follow to exercise the Change of Control Option.

(3) On or before the Expiration Date, each holder of shares of Preferred Stock wishing to exercise the Change of Control Option shall surrender the certificate or certificates representing the shares of Preferred Stock to be converted, in the manner and at the place designated in the notice described in Section 4(b), and on such date the cash or shares of Common Stock due to such holder shall be delivered to the Person whose name appears on such certificate or certificates as the owner thereof and the shares represented by each surrendered certificate shall be returned to authorized but unissued shares. Upon surrender (in accordance with the notice described in Section 4(b)) of the certificate or certificates representing any shares to be so converted (properly endorsed or assigned for transfer, if the Company shall so require and the notice shall so state), such shares shall be converted by the Company at the adjusted Conversion Price, if applicable, as described in Section 4(a).

9

(4) The rights of holders of Preferred Stock pursuant to this Section 4 are in addition to, and not in lieu of, the rights of holders of Preferred Stock provided for in Section 7 hereof.

5. Voting.

(1) The shares of Preferred Stock shall have no voting rights except as set forth below or as otherwise required by Oklahoma law from time to time:

(i) If and whenever at any time or times a Voting Rights Triggering Event occurs, then the holders of shares of Preferred Stock, voting as a single class with any other preferred stock or preference securities having similar voting rights that are exercisable (the “Voting Rights Class”), will be entitled at the next regular or special meeting of stockholders of the Company to elect two additional directors of the Company, unless the Board of Directors is comprised of fewer than six directors at such time, in which case the Voting Rights Class shall be entitled to elect one additional director. Upon the election of any such additional directors, the number of directors that comprise the Board of Directors shall be increased by such number of additional directors.

(ii) Such voting rights may be exercised at a special meeting of the holders of the shares of the Voting Rights Class, called as hereinafter provided, or at any annual meeting of stockholders held for the purpose of electing directors, and thereafter at each such annual meeting until such time as all dividends in arrears on the shares of Preferred Stock shall have been paid in full, at which time or times such voting rights and the term of the directors elected pursuant to Section 5(a)(i) shall terminate.

(iii) At any time when such voting rights shall have vested in holders of shares of the Voting Rights Class, an Officer of the Company may call, and, upon written request of the record holders of shares representing at least twenty-five percent (25%) of the voting power of the shares then outstanding of the Voting Rights Class, addressed to the Secretary of the Company, shall call a special meeting of the holders of shares of the Voting Rights Class. Such meeting shall be held at the earliest practicable date upon the notice required for annual meetings of stockholders at the place for holding annual meetings of stockholders of the Company, or, if none, at a place designated by the Board of Directors. Notwithstanding the provisions of this Section 5(a)(iii), no such special meeting shall be called during a period within the 60 days immediately preceding the date fixed for the next annual meeting of stockholders in which such case, the election of directors pursuant to Section 5(a)(i) shall be held at such annual meeting of stockholders.

10

(iv) At any meeting held for the purpose of electing directors at which the holders of the Voting Rights Class shall have the right to elect directors as provided herein, the presence in person or by proxy of the holders of shares representing more than fifty percent (50%) in voting power of the then outstanding shares of the Voting Rights Class shall be required and shall be sufficient to constitute a quorum of such class for the election of directors by such class. The affirmative vote of the holders of shares of Preferred Stock constituting a majority of the shares of Preferred Stock present at such meeting, in person or by proxy, shall be sufficient to elect any such director.

(v) Any director elected pursuant to the voting rights created under this Section 5(a) shall hold office until the next annual meeting of stockholders (unless such term has previously terminated pursuant to Section 5 (a)(ii)) and any vacancy in respect of any such director shall be filled only by vote of the remaining director so elected by holders of the Voting Rights Class, or if there be no such remaining director, by the holders of shares of the Voting Rights Class at a special meeting called in accordance with the procedures set forth in this Section 5, or, if no such special meeting is called, at the next annual meeting of stockholders. Upon any termination of such voting rights, the term of office of all directors elected pursuant to this Section 5 shall terminate.

(vi) So long as any shares of Preferred Stock remain outstanding, unless a greater percentage shall then be required by law, the Company shall not, without the affirmative vote or consent of the holders of at least 66 ²/3% of the outstanding Preferred Stock voting or consenting, as the case may be, separately as one class, (i) create, authorize or issue any class or series of Senior Stock (or any security convertible into Senior Stock) or (ii) amend the Certificate of Incorporation so as to affect adversely the specified rights, preferences, privileges or voting rights of holders of shares of Preferred Stock.

(vii) In exercising the voting rights set forth in this Section 5(a), each share of Preferred Stock shall be entitled to one vote.

(2) The Company may authorize, increase the authorized amount of, or issue any class or series of Parity Stock or Junior Stock, without the consent of the holders of Preferred Stock, and in taking such actions the Company shall not be deemed to have affected adversely the rights, preferences, privileges or voting rights of holders of shares of Preferred Stock.

11

6. Liquidation Rights.

(1) In the event of any liquidation, winding-up or dissolution of the Company, whether voluntary of involuntary, each holder of shares of Preferred Stock shall be entitled to receive and to be paid out of the assets of the Company available for distribution to its stockholders the Liquidation Preference plus Accumulated Dividends and Accrued Dividends thereon in preference to the holders of, and before any payment or distribution is made on, any Junior Stock, including, without limitation, on any Common Stock.

(2) Neither the sale, conveyance, exchange or transfer (for cash, shares of stock, securities or other consideration) of all or substantially all the assets or business of the Company (other than in connection with the liquidation, winding-up or dissolution of its business) nor the merger or consolidation of the Company into or with any other Person shall be deemed to be a liquidation, winding-up or dissolution, voluntary or involuntary, for the purposes of this Section 6.

(3) After the payment to the holders of the shares of Preferred Stock of full preferential amounts provided for in this Section 6, the holders of Preferred Stock as such shall have no right or claim to any of the remaining assets of the Company.

(4) In the event the assets of the Company available for distribution to the holders of shares of Preferred Stock upon any liquidation, winding-up or dissolution of the Company, whether voluntary or involuntary, shall be insufficient to pay in full all amounts to which such holders are entitled pursuant to Section 6(a), no such distribution shall be made on account of any shares of Parity Stock upon such liquidation, dissolution or winding-up unless proportionate distributable amounts shall be paid on account of the shares of Preferred Stock, ratably, in proportion to the full distributable amounts for which holders of all Preferred Stock and of any Parity Stock are entitled upon such liquidation, winding-up or dissolution.

7. Conversion.

(a) Each holder of Preferred Stock shall have the right, at its option, exercisable at any time and from time to time from the Issue Date to convert, subject to the terms and provisions of this Section 7, any or all of such holder’s shares of Preferred Stock. In such case, the shares of Preferred Stock shall be converted into such whole number of fully paid and nonassessable shares of Common Stock as is equal, subject to Section 7(g), to the product of the number of shares of Preferred Stock being so converted multiplied by the quotient of (i) the Liquidation Preference divided by (ii) the Conversion Price (as defined below) then in effect. The Conversion Price initially shall be $10.287, subject to adjustment as set forth in Section 7(c).

12

The conversion right of a holder of Preferred Stock shall be exercised by the holder by the surrender to the Company of the certificates representing shares to be converted at any time during usual business hours at its principal place of business or the offices of its duly appointed Transfer Agent to be maintained by it, accompanied by written notice to the Company in the form of Exhibit B that the holder elects to convert all or a portion of the shares of Preferred Stock represented by such certificate and specifying the name or names (with address) in which a certificate or certificates for shares of Common Stock are to be issued and (if so required by the Company or its duly appointed Transfer Agent) by a written instrument or instruments of transfer in form reasonably satisfactory to the Company or its duly appointed Transfer Agent duly executed by the holder or its duly authorized legal representative and transfer tax stamps or funds therefor, if required pursuant to Section 7(i). Immediately prior to the close of business on the date of receipt by the Company or its duly appointed Transfer Agent of notice of conversion of shares of Preferred Stock, each converting holder of Preferred Stock shall be deemed to be the holder of record of Common Stock issuable upon conversion of such holder’s Preferred Stock notwithstanding that the share register of the Company shall then be closed or that certificates representing such Common Stock shall not then be actually delivered to such holder. On the date of any conversion, all rights with respect to the shares of Preferred Stock so converted, including the rights, if any, to receive notices, will terminate, except only the rights of holders thereof to (i) receive certificates for the number of whole shares of Common Stock into which such shares of Preferred Stock have been converted and cash, in lieu of any fractional shares as provided in Section 7(f); and (ii) exercise the rights to which they are entitled as holders of Common Stock.

(b) If the last day for the exercise of the conversion right shall not be a Business Day, then such conversion right may be exercised on the next preceding Business Day.

13

(c) The Conversion Price shall be subject to adjustment as follows:

(i) In case the Company shall at any time or from time to time (A) pay a dividend (or other distribution) payable in shares of Common Stock on any class of capital stock (which, for purposes of this Section 7(c) shall include, without limitation, any dividends or distributions in the form of options, warrants or other rights to acquire capital stock) of the Company (other than the issuance of shares of Common Stock in connection with the conversion of preferred stock); (B) subdivide the outstanding shares of Common Stock into a larger number of shares; (C) combine the outstanding shares of Common Stock into a smaller number of shares; (D) issue any shares of its capital stock in a reclassification of the Common Stock; or (E) pay a dividend or make a distribution to all holders of shares of Common Stock (other than a dividend or distribution subject to Section 7(c)(ii)) pursuant to a stockholder rights plan, “poison pill” or similar arrangement and excluding dividends payable on the Preferred Stock then, and in each such case, the Conversion Price in effect immediately prior to such event shall be adjusted (and any other appropriate actions shall be taken by the Company) so that the holder of any share of Preferred Stock thereafter surrendered for conversion shall be entitled to receive the number of shares of Common Stock that such holder would have owned or would have been entitled to receive upon or by reason of any of the events described above, had such share of Preferred Stock been converted into shares of Common Stock immediately prior to the occurrence of such event. An adjustment made pursuant to this Section 7(c)(i) shall become effective retroactively (x) in the case of any such dividend or distribution, to the day immediately following the close of business on the record date for the determination of holders of Common Stock entitled to receive such dividend or distribution or (y) in the case of any such subdivision, combination or reclassification, to the close of business on the day upon which such corporate action becomes effective.

(ii) In case the Company shall at any time or from time to time issue to all holders of its Common Stock rights, options or warrants entitling the holders thereof to subscribe for or purchase shares of Common Stock (or securities convertible into or exchangeable for shares of Common Stock) at a price per share less than the Market Value for the period ending on the date of issuance (treating the price per share of any security convertible, or exchangeable or exercisable into Common Stock as equal to (A) the sum of the price paid to acquire such security convertible, exchangeable or exercisable into Common Stock plus any additional consideration payable (without regard to any anti-dilution adjustments) upon the conversion, exchange or exercise of such security into Common Stock divided by (B) the number of shares of Common Stock into which such convertible, exchangeable or exercisable security is initially convertible, exchangeable or exercisable), other than (I) issuances of such rights, options or warrants if the holder of Preferred Stock would be entitled to receive such rights, options or warrants upon conversion at any time of shares of Preferred Stock into Common Stock and (II) issuances that are subject to certain triggering events (until such time as such triggering events occur), then, and in each such case, the Conversion Price then in effect shall be adjusted by dividing the Conversion Price in effect on the day immediately prior to the record date

14

of such issuance by a fraction (y) the numerator of which shall be the sum of the number of shares of Common Stock outstanding on such record date plus the number of additional shares of Common Stock issued or to be issued upon or as a result of the issuance of such rights, options or warrants (or the maximum number into or for which such convertible or exchangeable securities initially may convert or exchange or for which such options, warrants or other rights initially may be exercised) and (z) the denominator of which shall be the sum of the number of shares of Common Stock outstanding on such record date plus the number of shares of Common Stock which the aggregate consideration for the total number of such additional shares of Common Stock so issued (or into or for which such convertible or exchangeable securities may convert or exchange or for which such options, warrants or other rights may be exercised plus the aggregate amount of any additional consideration initially payable upon the conversion, exchange or exercise of such security) would purchase at the Market Value for the period ending on the date of conversion; provided, that if the Company distributes rights or warrants (other than those referred to above in this subparagraph (c)(ii)) pro rata to the holders of Common Stock, so long as such rights or warrants have not expired or been redeemed by the Company, (y) the holder of any Preferred Stock surrendered for conversion shall be entitled to receive upon such conversion, in addition to the shares of Common Stock then issuable upon such conversion (the “Conversion Shares”), a number of rights or warrants to be determined as follows: (i) if such conversion occurs on or prior to the date for the distribution to the holders of rights or warrants of separate certificates evidencing such rights or warrants (the “Distribution Date”), the same number of rights or warrants to which a holder of a number of shares of Common Stock equal to the number of Conversion Shares is entitled at the time of such conversion in accordance with the terms and provisions applicable to the rights or warrants and (ii) if such conversion occurs after the Distribution Date, the same number of rights or warrants to which a holder of the number of shares of Common Stock into which such Preferred Stock was convertible immediately prior to such Distribution Date would have been entitled on such Distribution Date had such Preferred Stock been converted immediately prior to such Distribution Date in accordance with the terms and provisions applicable to the rights and warrants, and (z) the Conversion Price shall not be subject to adjustment on account of any declaration, distribution or exercise of such rights or warrants.

(iii) In case the Company shall at any time or from time to time (A) make a pro rata distribution to all holders of shares of its Common Stock consisting exclusively of cash (excluding any cash portion of distributions referred to in clause (E) of paragraph (c)(i) above, or cash distributed upon a merger or consolidation to which paragraph (g) below applies), that, when combined together with (x) all other such all-cash distributions made within the then-preceding 12 months in respect of which no adjustment has been made and (y) any cash and the fair market value of other consideration paid or payable in respect of any tender offer by the Company or any of its subsidiaries for shares of Common Stock concluded within the then-preceding 12 months in respect of which no

15

adjustment pursuant to this Section 7(c) has been made, in the aggregate exceeds 15% of the Company’s market capitalization (defined as the product of the Market Value for the period ending on the record date of such distribution times the number of shares of Common Stock outstanding on such record date) on the record date of such distribution; (B) complete a tender or exchange offer by the Company or any of its subsidiaries for shares of Common Stock that involves an aggregate consideration that, together with (I) any cash and other consideration payable in a tender or exchange offer by the Company or any of its subsidiaries for shares of Common Stock expiring within the then-preceding 12 months in respect of which no adjustment pursuant to this Section 7(c) has been made and (II) the aggregate amount of any such all-cash distributions referred to in clause (A) above to all holders of shares of Common Stock within the then-preceding 12 months in respect of which no adjustments have been made, exceeds 15% of the Company’s market capitalization on the expiration of such tender offer; or (C) make a distribution to all holders of its Common Stock consisting of evidences of indebtedness, shares of its capital stock other than Common Stock or assets (including securities, but excluding those dividends, rights, options, warrants and distributions referred to in paragraphs (c)(i), (c)(ii) above or this (c)(iii)), then, and in each such case, the Conversion Price then in effect shall be adjusted by dividing the Conversion Price in effect immediately prior to the date of such distribution or completion of such tender or exchange offer, as the case may be, by a fraction (x) the numerator of which shall be the Market Value for the period ending on the record date referred to below, or, if such adjustment is made upon the completion of a tender or exchange offer, on the payment date for such offer, and (y) the denominator of which shall be such Market Value less the then fair market value (as determined by the Board of Directors of the Company) of the portion of the cash, evidences of indebtedness, securities or other assets so distributed or paid in such tender or exchange offer, applicable to one share of Common Stock (but such denominator shall not be less than one); provided, however, that no adjustment shall be made with respect to any distribution of rights to purchase securities of the Company if the holder of shares of Preferred Stock would otherwise be entitled to receive such rights upon conversion at any time of shares of Preferred Stock into shares of Common Stock unless such rights are subsequently redeemed by the Company, in which case such redemption shall be treated for purposes of this Section 7(c)(iii) as a dividend on the Common Stock. Such adjustment shall be made whenever any such distribution is made or tender or exchange offer is completed, as the case may be, and shall become effective retroactively to a date immediately following the close of business on the record date for the determination of stockholders entitled to receive such distribution.

(iv) In the case the Company at any time or from time to time shall take any action affecting its Common Stock (it being understood that the issuance or sale of shares of Common Stock (or securities convertible into or exchangeable for shares of Common Stock, or any options, warrants or other rights to acquire shares of Common Stock) to any Person at a price per share less than the Conversion Price then in effect shall not be deemed such an action), other than an action described in any of Section 7(c)(i) through

16

Section 7(c)(iii), inclusive, or Section 7(g), then the Conversion Price shall be adjusted in such manner and at such time as the Board of Directors of the Company in good faith determines to be equitable in the circumstances (such determination to be evidenced in a resolution, a certified copy of which shall be mailed to the holders of the Preferred Stock).

(v) Notwithstanding anything herein to the contrary, no adjustment under this Section 7(c) need be made to the Conversion Price unless such adjustment would require an increase or decrease of at least 1% of the Conversion Price then in effect. Any lesser adjustment shall be carried forward and shall be made at the time of and together with the next subsequent adjustment, if any, which, together with any adjustment or adjustments so carried forward, shall amount to an increase or decrease of at least 1% of such Conversion Price.

(vi) The Company reserves the right to make such reductions in the Conversion Price in addition to those required in the foregoing provisions as it considers advisable in order that any event treated for Federal income tax purposes as a dividend of stock or stock rights will not be taxable to the recipients. In the event the Company elects to make such a reduction in the Conversion Price, the Company will comply with the requirements of Rule 14e-1 under the Exchange Act, and any other securities laws and regulations thereunder if and to the extent that such laws and regulations are applicable in connection with the reduction of the Conversion Price.

(d) If the Company shall take a record of the holders of its Common Stock for the purpose of entitling them to receive a dividend or other distribution, and shall thereafter (and before the dividend or distribution has been paid or delivered to stockholders) legally abandon its plan to pay or deliver such dividend or distribution, then thereafter no adjustment in the Conversion Price then in effect shall be required by reason of the taking of such record.

(e) Upon any increase or decrease in the Conversion Price, then, and in each such case, the Company promptly shall deliver to each holder of Preferred Stock a certificate signed by an authorized officer of the Company, setting forth in reasonable detail the event requiring the adjustment and the method by which such adjustment was calculated and specifying the increased or decreased Conversion Price then in effect following such adjustment.

(f) No fractional shares or securities representing fractional shares of Common Stock shall be issued upon the conversion of any shares of Preferred Stock, whether voluntary or mandatory. If more than one share of Preferred Stock shall be surrendered for conversion at one time by the same holder, the number of full shares of Common Stock issuable upon conversion thereof shall be computed on the basis of the aggregate Liquidation Preference of the shares of Preferred Stock so surrendered. If the

17

conversion of any share or shares of Preferred Stock results in a fraction, an amount equal to such fraction multiplied by the last reported sale price of the Common Stock on the NYSE (or on such other national securities exchange or automated quotation system on which the Common Stock is then listed for trading or authorized for quotation or, if the Common Stock is not then so listed or authorized for quotation, an amount determined in good faith by the Board of Directors to be the fair value of the Common Stock) at the close of business on the trading day next preceding the day of conversion shall be paid to such holder in cash by the Company.

(g) In the event of any reclassification of outstanding shares of Common Stock (other than a change in par value, or from par value to no par value, or from no par value to par value), or in the event of any consolidation or merger of the Company with or into another Person or any merger of another Person with or into the Company (other than a consolidation or merger in which the Company is the resulting or surviving Person and which does not result in any reclassification or change of outstanding Common Stock), or in the event of any sale or other disposition to another Person of all or substantially all of the assets of the Company (computed on a consolidated basis) (any of the foregoing, a “Transaction”), each share of Preferred Stock then outstanding shall, without the consent of any holder of Preferred Stock, become convertible at any time, at the option of the holder thereof, only into the kind and amount of securities (of the Company or another issuer), cash and other property receivable upon such Transaction by a holder of the number of shares of Common Stock into which such share of Preferred Stock could have been converted immediately prior to such Transaction, after giving effect to any adjustment event. The provisions of this Section 7(g) and any equivalent thereof in any such securities similarly shall apply to successive Transactions. The provisions of this Section 7(g) shall be the sole right of holders of Preferred Stock in connection with any Transaction and such holders shall have no separate vote thereon.

(h) The Company shall at all times reserve and keep available for issuance upon the conversion of the Preferred Stock such number of its authorized but unissued shares of Common Stock as will from time to time be sufficient to permit the conversion of all outstanding shares of Preferred Stock, and shall take all action required to increase the authorized number of shares of Common Stock if at any time there shall be insufficient unissued shares of Common Stock to permit such reservation or to permit the conversion of all outstanding shares of Preferred Stock.

(i) The issuance or delivery of certificates for Common Stock upon the conversion of shares of Preferred Stock shall be made without charge to the converting holder of shares of Preferred Stock for such certificates or for any tax in respect of the issuance or delivery of such certificates or the securities represented thereby, and such certificates shall be issued or delivered in the respective names of, or in such names as may be directed by, the holders of the shares of Preferred Stock converted; provided, however, that the Company shall not be required to pay any tax which may be payable in

18

respect of any transfer involved in the issuance and delivery of any such certificate in a name other than that of the holder of the shares of Preferred Stock converted, and the Company shall not be required to issue or deliver such certificate unless or until the Person or Persons requesting the issuance or delivery thereof shall have paid to the Company the amount of such tax or shall have established to the reasonable satisfaction of the Company that such tax has been paid.

8. Mandatory Conversion.

(a) At any time on or after March 20, 2006, the Company shall have the right, at its option, to cause the Preferred Stock, in whole but not in part, to be automatically converted into that number of whole shares of Common Stock for each share of Preferred Stock equal to the quotient of (i) the Liquidation Preference divided by (ii) the Conversion Price then in effect, with any resulting fractional shares of Common Stock to be settled in accordance with Section 7(f). The Company may exercise its right to cause a mandatory conversion pursuant to this Section 8(a) only if the closing price of the Common Stock equals or exceeds 130% of the Conversion Price then in effect for at least 20 trading days in any consecutive 30-day trading period on the NYSE (or such other national securities exchange or automated quotation system on which the Common Stock is then listed or authorized for quotation, including the last trading day of such 30-day period, ending on the trading day prior to the Company’s issuance of a press release announcing the mandatory conversion as described in Section 8(b).

(b) To exercise the mandatory conversion right described in Section 8(a), the Company must issue a press release for publication on the Dow Jones News Service prior to the opening of business on the first trading day following any date on which the conditions described in Section 8(a) are met, announcing such a mandatory conversion. The Company shall also give notice by mail or by publication (with subsequent prompt notice by mail) to the holders of Preferred Stock (not more than four Business Days after the date of the press release) of the mandatory conversion announcing the Company’s intention to convert the Preferred Stock. The conversion date will be a date selected by the Company (the “Mandatory Conversion Date”) and will be no more than five days after the date on which the Company issues the press release described in this Section 8(b).

(c) In addition to any information required by applicable law or regulation, the press release and notice of a mandatory conversion described in Section 8(b) shall state, as appropriate: (i) the Mandatory Conversion Date; (ii) the number of shares of Common Stock to be issued upon conversion of each share of Preferred Stock; (iii) the number of shares of Preferred Stock to be converted; and (iv) that dividends on the Preferred Stock to be converted will cease to accrue on the Mandatory Conversion Date.

19

(d) On and after the Mandatory Conversion Date, dividends will cease to accrue on the Preferred Stock called for a mandatory conversion pursuant to Section 8(a) and all rights of holders of such Preferred Stock will terminate except for the right to receive the whole shares of Common Stock issuable upon conversion thereof and cash, in lieu of any fractional shares of Common Stock in accordance with Section 7(f). The dividend payment with respect to the Preferred Stock called for a mandatory conversion pursuant to Section 8(a) on a date during the period between the close of business on any Dividend Record Date to the close of business on the corresponding Dividend Payment Date will be payable on such Dividend Payment Date to the record holder of such share on such Dividend Record Date if such share has been converted after such Dividend Record Date and prior to such Dividend Payment Date. Except as provided in the immediately preceding sentence with respect to a mandatory conversion pursuant to Section 8(a), no payment or adjustment will be made upon conversion of Preferred Stock for Accrued Dividends or for dividends with respect to the Common Stock issued upon such conversion.

(e) The Company may not authorize, issue a press release or give notice of any mandatory conversion pursuant to Section 8(a) unless, prior to giving the conversion notice, all Accumulated Dividends on the Preferred Stock for periods ended prior to the date of such conversion notice shall have been paid in cash.

(f) In addition to the mandatory conversion right described in Section 8(a), if there are less than 250,000 shares of Preferred Stock outstanding, the Company shall have the right, at any time on or after March 20, 2008, at its option, to cause the Preferred Stock to be automatically converted into that number of whole shares of Common Stock equal to the quotient of (i) the Liquidation Preference divided by (ii) the lesser of (A) the Conversion Price then in effect and (B) the Market Value for the period ending on the second trading day immediately prior to the Mandatory Conversion Date, with any resulting fractional shares of Common Stock to be settled in cash in accordance with Section 7(f). The provisions of clauses (b), (c), (d) and (e) of this Section 8 shall apply to any mandatory conversion pursuant to this clause (f); provided that (i) the Mandatory Conversion Date described in Section 8(b) shall not be less than 15 days nor more than 30 days after the date on which the Company issues a press release pursuant to Section 8(b) announcing such mandatory conversion and (ii) the press release and notice of mandatory conversion described in Section 8(c) will not state the number of shares of Common Stock to be issued upon conversion of each share of Preferred Stock.

9. Consolidation, Merger and Sale of Assets.

(a) The Company, without the consent of the holders of any of the outstanding Preferred Stock, may consolidate with or merge into any other Person or convey, transfer or lease all or substantially all its assets to any Person or may permit any Person to consolidate with or merge into, or transfer or lease all or substantially all its

20

properties to, the Company; provided, however, that (a) the successor, transferee or lessee is organized under the laws of the United States or any political subdivision thereof; (b) the shares of Preferred Stock will become shares of such successor, transferee or lessee, having in respect of such successor, transferee or lessee the same powers, preferences and relative participating, optional or other special rights and the qualification, limitations or restrictions thereon, the Preferred Stock had immediately prior to such transaction; and (c) the Company delivers to the Transfer Agent an Officers’ Certificate and an Opinion of Counsel stating that such transaction complies with this Certificate of Designation.

(b) Upon any consolidation by the Company with, or merger by the Company into, any other person or any conveyance, transfer or lease of all or substantially all the assets of the Company as described in Section 9(a), the successor resulting from such consolidation or into which the Company is merged or the transferee or lessee to which such conveyance, transfer or lease is made, will succeed to, and be substituted for, and may exercise every right and power of, the Company under the shares of Preferred Stock, and thereafter, except in the case of a lease, the predecessor (if still in existence) will be released from its obligations and covenants with respect to the Preferred Stock.

10. SEC Reports.

Whether or not the Company is required to file reports with the Commission, if any shares of Preferred Stock are outstanding, the Company shall file with the Commission all such reports and other information as it would be required to file with the Commission by Section 13(a)or 15(d) under the Exchange Act. The Company shall supply each holder of Preferred Stock, upon request, without cost to such holder, copies of such reports or other information.

11. Certificates.

(a) Form and Dating. The Preferred Stock and the Transfer Agent’s certificate of authentication shall be substantially in the form of Exhibit A, which is hereby incorporated in and expressly made a part of this Certificate of Designation. The Preferred Stock certificate may have notations, legends or endorsements required by law, stock exchange rule, agreements to which the Company is subject, if any, or usage (provided that any such notation, legend or endorsement is in a form acceptable to the Company). Each Preferred Stock certificate shall be dated the date of its authentication. The terms of the Preferred Stock certificate set forth in Exhibit A are part of the terms of this Certificate of Designation.

(i) Global Preferred Stock. The Preferred Stock shall be issued initially in the form of one or more fully registered global certificates with the global securities legend and restricted securities legend set forth in Exhibit A hereto (the “Global Preferred

21

Stock”), which shall be deposited on behalf of the purchasers represented thereby with the Transfer Agent, as custodian for DTC (or with such other custodian as DTC may direct), and registered in the name of DTC or a nominee of DTC, duly executed by the Company and authenticated by the Transfer Agent as hereinafter provided. The number of shares of Preferred Stock represented by Global Preferred Stock may from time to time be increased or decreased by adjustments made on the records of the Transfer Agent and DTC or its nominee as hereinafter provided. With respect to shares of Preferred Stock that are not “restricted securities” as defined in Rule 144 on a conversion date, all shares of Common Stock distributed on such conversion date will be freely transferable without restriction under the Securities Act (other than by affiliates), and such shares will be eligible for receipt in global form through the facilities of DTC.

(ii) Book-Entry Provisions. In the event Global Preferred Stock is deposited with or on behalf of DTC, the Company shall execute and the Transfer Agent shall authenticate and deliver initially one or more Global Preferred Stock certificates that (a) shall be registered in the name of DTC as depository for such Global Preferred Stock or the nominee of DTC and (b) shall be delivered by the Transfer Agent to DTC or pursuant to DTC’s instructions or held by the Transfer Agent as custodian for DTC.

Members of, or participants in, DTC (“Agent Members”) shall have no rights under this Certificate of Designation with respect to any Global Preferred Stock held on their behalf by DTC or by the Transfer Agent as the custodian of DTC or under such Global Preferred Stock, and DTC may be treated by the Company, the Transfer Agent and any agent of the Company or the Transfer Agent as the absolute owner of such Global Preferred Stock for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Transfer Agent or any agent of the Company or the Transfer Agent from giving effect to any written certification, proxy or other authorization furnished by DTC or impair, as between DTC and its Agent Members, the operation of customary practices of DTC governing the exercise of the rights of a holder of a beneficial interest in any Global Preferred Stock.

(iii) Certificated Preferred Stock; Certificated Common Stock. Except as provided in this paragraph 11(a) or in paragraph 11(c), owners of beneficial interests in Global Preferred Stock will not be entitled to receive physical delivery of Preferred Stock in fully registered certificated form (“Certificated Preferred Stock”). With respect to shares of Preferred Stock that are “restricted securities” as defined in Rule 144 on a conversion date, all shares of Common Stock issuable on conversion of such shares on such conversion date will be issued in fully registered certificated form (“Certificated Common Stock”). Certificates of Certificated Common Stock will be mailed or made available at the office of the Transfer Agent for the Preferred Stock on or as soon as reasonably practicable after the relevant conversion date to the converting holder.

22

After a transfer of any Preferred Stock or Certificated Common Stock during the period of the effectiveness of a Shelf Registration Statement with respect to such Preferred Stock or such Certificated Common Stock, all requirements pertaining to legends on such Preferred Stock (including Global Preferred Stock) or Certificated Common Stock will cease to apply, the requirements requiring that any such Certificated Common Stock issued to Holders be issued in certificated form, as the case may, will cease to apply, and Preferred Stock or Common Stock, as the case may be, in global or fully registered certificated form, in either case without legends, will be available to the transferee of the Holder of such Preferred Stock or Certificated Common Stock upon exchange of such transferring Holder’s Preferred Stock or Common Stock or directions to transfer such Holder’s interest in the Global Preferred Stock, as applicable.

(b) Execution and Authentication. Two Officers shall sign the Preferred Stock certificate for the Company by manual or facsimile signature.

If an Officer whose signature is on a Preferred Stock certificate no longer holds that office at the time the Transfer Agent authenticates the Preferred Stock certificate, the Preferred Stock certificate shall be valid nevertheless.

A Preferred Stock certificate shall not be valid until an authorized signatory of the Transfer Agent manually signs the certificate of authentication on the Preferred Stock certificate. The signature shall be conclusive evidence that the Preferred Stock certificate has been authenticated under this Certificate of Designation.

The Transfer Agent shall authenticate and deliver certificates for up to 4,600,000 shares of Preferred Stock for original issue upon a written order of the Company signed by two Officers or by an Officer and an Assistant Treasurer of the Company. Such order shall specify the number of shares of Preferred Stock to be authenticated and the date on which the original issue of Preferred Stock is to be authenticated.

The Transfer Agent may appoint an authenticating agent reasonably acceptable to the Company to authenticate the certificates for Preferred Stock. Unless limited by the terms of such appointment, an authenticating agent may authenticate certificates for Preferred Stock whenever the Transfer Agent may do so. Each reference in this Certificate of Designation to authentication by the Transfer Agent includes authentication by such agent. An authenticating agent has the same rights as the Transfer Agent or agent for service of notices and demands.

23

(c) Transfer and Exchange. (i) Transfer and Exchange of Certificated Preferred Stock. When Certificated Preferred Stock is presented to the Transfer Agent with a request to register the transfer of such Certificated Preferred Stock or to exchange such Certificated Preferred Stock for an equal number of shares of Certificated Preferred Stock, the Transfer Agent shall register the transfer or make the exchange as requested if its reasonable requirements for such transaction are met; provided, however, that the Certificated Preferred Stock surrendered for transfer or exchange:

(1) shall be duly endorsed or accompanied by a written instrument of transfer in form reasonably satisfactory to the Company and the Transfer Agent, duly executed by the Holder thereof or its attorney duly authorized in writing; and

(2) is being transferred or exchanged pursuant to an effective registration statement under the Securities Act or pursuant to clause (I) or (II) below, and is accompanied by the following additional information and documents, as applicable:

(I) if such Certificated Preferred Stock is being delivered to the Transfer Agent by a Holder for registration in the name of such Holder, without transfer, a certification from such Holder to that effect in substantially the form of Exhibit C hereto; or

(II) if such Certificated Preferred Stock is being transferred to the Company or to a “qualified institutional buyer” (“QIB”) in accordance with Rule 144A under the Securities Act or pursuant to another exemption from registration under the Securities Act, (i) a certification to that effect (in substantially the form of Exhibit C hereto) and (ii) if the Company so requests, an Opinion of Counsel or other evidence reasonably satisfactory to it as to the compliance with the restrictions set forth in the legend set forth in paragraph 11 (c) (vii).

24

(ii) Restrictions on Transfer of Certificated Preferred Stock for a Beneficial Interest in Global Preferred Stock. Certificated Preferred Stock may not be exchanged for a beneficial interest in Global Preferred Stock except upon satisfaction of the requirements set forth below. Upon receipt by the Transfer Agent of Certificated Preferred Stock, duly endorsed or accompanied by appropriate instruments of transfer, in form reasonably satisfactory to the Company and the Transfer Agent, together with written instructions directing the Transfer Agent to make, or to direct DTC to make, an adjustment on its books and records with respect to such Global Preferred Stock to reflect an increase in the number of shares of Preferred Stock represented by the Global Preferred Stock, then the Transfer Agent shall cancel such Certificated Preferred Stock and cause, or direct DTC to cause, in accordance with the standing instructions and procedures existing between DTC and the Transfer Agent, the number of shares of Preferred Stock represented by the Global Preferred Stock to be increased accordingly. If no Global Preferred Stock is then outstanding, the Company shall issue and the Transfer Agent shall authenticate, upon written order of the Company in the form of an Officers’ Certificate, a new Global Preferred Stock representing the appropriate number of shares.

(iii) Transfer and Exchange of Global Preferred Stock. The transfer and exchange of Global Preferred Stock or beneficial interests therein shall be effected through DTC, in accordance with this Certificate of Designation (including applicable restrictions on transfer set forth herein, if any) and the procedures of DTC therefor.

(iv) Transfer of a Beneficial Interest in Global Preferred Stock for a Certificated Preferred Stock.

(1) Any Person having a beneficial interest in Preferred Stock that is being transferred or exchanged pursuant to an effective registration statement under the Securities Act or pursuant to another exemption from registration thereunder may upon request, but only with the consent of the Company, and if accompanied by a certification from such Person to that effect (in substantially the form of Exhibit C hereto), exchange such beneficial interest for Certificated Preferred Stock representing the same number of shares of Preferred Stock. Upon receipt by the Transfer Agent of written instructions or such other form of instructions as is customary for DTC from DTC or its nominee on behalf of any Person having a beneficial interest in Global Preferred Stock and upon receipt by the Transfer Agent of a written order or such other form of instructions as is customary for DTC or the Person designated by DTC as having such a beneficial interest in a Transfer Restricted Security only, then, the Transfer Agent or DTC, at the direction of the Transfer Agent, will cause, in accordance with the standing instructions and procedures existing between DTC and the Transfer Agent, the number of shares of Preferred Stock represented by Global Preferred Stock to be reduced on its books and records and, following such reduction, the Company will execute and the Transfer Agent will authenticate and deliver to the transferee Certificated Preferred Stock.

25

(2) Certificated Preferred Stock issued in exchange for a beneficial interest in a Global Preferred Stock pursuant to this paragraph 11(c)(iv) shall be registered in such names and in such authorized denominations as DTC, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Transfer Agent. The Transfer Agent shall deliver such Certificated Preferred Stock to the Persons in whose names such Preferred Stock are so registered in accordance with the instructions of DTC.

(v) Restrictions on Transfer and Exchange of Global Preferred Stock.

(1) Notwithstanding any other provisions of this Certificate of Designation (other than the provisions set forth in paragraph 11(c)(vi)), Global Preferred Stock may not be transferred as a whole except by DTC to a nominee of DTC or by a nominee of DTC to DTC or another nominee of DTC or by DTC or any such nominee to a successor depository or a nominee of such successor depository.

(2) In the event that the Global Preferred Stock is exchanged for Preferred Stock in definitive registered form pursuant to paragraph 11(c)(vi) prior to the effectiveness of a Shelf Registration Statement with respect to such securities, such Preferred Stock may be exchanged only in accordance with such procedures as are substantially consistent with the provisions of this paragraph 11(c) (including the certification requirements set forth in the Exhibits to this Certificate of Designation intended to ensure that such transfers comply with Rule 144A or such other applicable exemption from registration under the Securities Act, as the case may be) and such other procedures as may from time to time be adopted by the Company.

(vi) Authentication of Certificated Preferred Stock. If at any time:

(1) DTC notifies the Company that DTC is unwilling or unable to continue as depository for the Global Preferred Stock and a successor depository for the Global Preferred Stock is not appointed by the Company within 90 days after delivery of such notice;

(2) DTC ceases to be a clearing agency registered under the Exchange Act and a successor depository for the Global Preferred Stock is not appointed by the Company within 90 days; or

26

(3) the Company, in its sole discretion, notifies the Transfer Agent in writing that it elects to cause the issuance of Certificated Preferred Stock under this Certificate of Designation,

then the Company will execute, and the Transfer Agent, upon receipt of a written order of the Company signed by two Officers or by an Officer and an Assistant Treasurer of the Company requesting the authentication and delivery of Certificated Preferred Stock to the Persons designated by the Company, will authenticate and deliver Certificated Preferred Stock equal to the number of shares of Preferred Stock represented by the Global Preferred Stock, in exchange for such Global Preferred Stock.

27

(vii) Legend. (1) Except as permitted by the following paragraph (2) and in paragraph 11(a)(iii), each certificate evidencing the Global Preferred Stock, the Certificated Preferred Stock and Certificated Common Stock shall bear a legend in substantially the following form:

“THE SECURITY EVIDENCED HEREBY (OR ITS PREDECESSOR) WAS ORIGINALLY ISSUED IN A TRANSACTION EXEMPT FROM REGISTRATION UNDER THE UNITED STATES SECURITIES ACT OF 1933 (THE “SECURITIES ACT”), AND THIS SECURITY (AND THE COMMON STOCK INTO WHICH THIS SECURITY IS CONVERTIBLE) MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM. EACH PURCHASER OF THE SECURITY EVIDENCED HEREBY IS HEREBY NOTIFIED THAT THE SELLER MAY BE RELYING ON THE EXEMPTION FROM THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER. THE HOLDER OF THE SECURITY EVIDENCED HEREBY AGREES FOR THE BENEFIT OF THE COMPANY THAT (A) SUCH SECURITY (AND THE COMMON STOCK INTO WHICH THIS SECURITY IS CONVERTIBLE) MAY BE OFFERED, RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (1) IN THE UNITED STATES TO A PERSON WHO THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) PURCHASING FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A, (2) OUTSIDE OF THE UNITED STATES IN AN OFFSHORE TRANSACTION IN ACCORDANCE WITH RULE 904 UNDER THE SECURITIES ACT, (3) PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER (IF AVAILABLE), (4) TO THE COMPANY OR (5) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, IN EACH OF CASES (1) THROUGH (5) IN ACCORDANCE WITH ALL APPLICABLE SECURITIES LAWS OF THE STATES OF THE UNITED STATES AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS REQUIRED TO, NOTIFY ANY PURCHASER OF THIS SECURITY FROM IT OF THE RESALE RESTRICTIONS REFERRED TO IN (A) ABOVE. IN ANY CASE, THE HOLDER OF THIS SECURITY WILL NOT, DIRECTLY OR INDIRECTLY, ENGAGE IN ANY HEDGING TRANSACTION WITH REGARD TO THE SECURITY EXCEPT AS PERMITTED UNDER THE SECURITIES ACT.” (1)

1 Subject to removal upon registration under the Securities Act of 1933 or otherwise when the security shall no longer be a Transfer Restricted Security.

28

(2) Upon any sale or transfer of a Transfer Restricted Security (including any Transfer Restricted Security represented by Global Preferred Stock) pursuant to Rule 144 under the Securities Act or another exemption from registration under the Securities Act or an effective registration statement under the Securities Act:

(I) in the case of any Transfer Restricted Security that is a Certificated Preferred Stock, the Transfer Agent shall permit the Holder thereof to exchange such Transfer Restricted Security for Certificated Preferred Stock that does not bear the legend set forth above and rescind any restriction on the transfer of such Transfer Restricted Security; and

(II) in the case of any Transfer Restricted Security that is represented by a Global Preferred Stock, with the consent of the Company, the Transfer Agent shall permit the Holder thereof to exchange such Transfer Restricted Security for Certificated Preferred Stock that does not bear the legend set forth above and rescind any restriction on the transfer of such Transfer Restricted Security, if the Holder’s request for such exchange was made in reliance on Rule 144 or another exemption from registration under the Securities Act and the Holder certifies to that effect in writing to the Transfer Agent (such certification to be in the form set forth in Exhibit C hereto).

(viii) Cancelation or Adjustment of Global Preferred Stock. At such time as all beneficial interests in Global Preferred Stock have either been exchanged for Certificated Preferred Stock, converted or canceled, such Global Preferred Stock shall be returned to DTC for cancelation or retained and canceled by the Transfer Agent. At any time prior to such cancelation, if any beneficial interest in Global Preferred Stock is exchanged for Certificated Preferred Stock, converted or canceled, the number of shares of Preferred Stock represented by such Global Preferred Stock shall be reduced and an adjustment shall be made on the books and records of the Transfer Agent with respect to such Global Preferred Stock, by the Transfer Agent or DTC, to reflect such reduction.

(ix) Obligations with Respect to Transfers and Exchanges of Preferred Stock. (1) To permit registrations of transfers and exchanges, the Company shall execute and the Transfer Agent shall authenticate Certificated Preferred Stock and Global Preferred Stock as required pursuant to the provisions of this paragraph 11(c).

(2) All Certificated Preferred Stock and Global Preferred Stock issued upon any registration of transfer or exchange of Certificated Preferred Stock or Global Preferred Stock shall be the valid obligations of the Company, entitled to the same benefits under this Certificate of Designation as the Certificated Preferred Stock or Global Preferred Stock surrendered upon such registration of transfer or exchange.

29

(3) Prior to due presentment for registration of transfer of any shares of Preferred Stock, the Transfer Agent and the Company may deem and treat the Person in whose name such shares of Preferred Stock are registered as the absolute owner of such Preferred Stock and neither the Transfer Agent nor the Company shall be affected by notice to the contrary.

(4) No service charge shall be made to a Holder for any registration of transfer or exchange upon surrender of any Preferred Stock certificate or Common Stock certificate at the office of the Transfer Agent maintained for that purpose. However, the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Preferred Stock certificates or Common Stock certificates.

(5) Upon any sale or transfer of shares of Preferred Stock (including any Preferred Stock represented by a Global Preferred Stock Certificate) or of Certificated Common Stock pursuant to an effective registration statement under the Securities Act or pursuant to Rule 144 or another exemption from registration under the Securities Act (and based upon an Opinion of Counsel reasonably satisfactory to the Company if it so requests):

(A) in the case of any Certificated Preferred Stock or Certificated Common Stock, the Company and the Transfer Agent shall permit the holder thereof to exchange such Preferred Stock or Certificated Common Stock for Certificated Preferred Stock or Certificated Common Stock, as the case may be, that does not bear the legend set forth in paragraph (c)(vii) above and rescind any restriction on the transfer of such Preferred Stock or Common Stock issuable in respect of the conversion of the Preferred Stock; and

(B) in the case of any Global Preferred Stock, such Preferred Stock shall not be required to bear the legend set forth in paragraph (c)(vii) above but shall continue to be subject to the provisions of paragraph (c)(iv) hereof; provided, however, that with respect to any request for an exchange of Preferred Stock that is represented by Global Preferred Stock for Certificated Preferred Stock that does not bear the legend set forth in paragraph (c)(vii) above in connection with a sale or transfer thereof pursuant to Rule 144 or another exemption from registration under the Securities Act (and based upon an Opinion of Counsel if the

30

Company so requests), the Holder thereof shall certify in writing to the Transfer Agent that such request is being made pursuant to such exemption (such certification to be substantially in the form of Exhibit C hereto).

(x) No Obligation of the Transfer Agent.

(1) The Transfer Agent shall have no responsibility or obligation to any beneficial owner of Global Preferred Stock, a member of, or a participant in DTC or any other Person with respect to the accuracy of the records of DTC or its nominee or of any participant or member thereof, with respect to any ownership interest in the Preferred Stock or with respect to the delivery to any participant, member, beneficial owner or other Person (other than DTC) of any notice or the payment of any amount, under or with respect to such Global Preferred Stock. All notices and communications to be given to the Holders and all payments to be made to Holders under the Preferred Stock shall be given or made only to the Holders (which shall be DTC or its nominee in the case of the Global Preferred Stock). The rights of beneficial owners in any Global Preferred Stock shall be exercised only through DTC subject to the applicable rules and procedures of DTC. The Transfer Agent may rely and shall be fully protected in relying upon information furnished by DTC with respect to its members, participants and any beneficial owners.

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

(d) Replacement Certificates. If a mutilated Preferred Stock certificate is surrendered to the Transfer Agent or if the Holder of a Preferred Stock certificate claims that the Preferred Stock certificate has been lost, destroyed or wrongfully taken, the Company shall issue and the Transfer Agent shall countersign a replacement Preferred Stock certificate if the reasonable requirements of the Transfer Agent and of Section 8-405 of the Uniform Commercial Code as in effect in the State of Oklahoma are met. If required by the Transfer Agent or the Company, such Holder shall furnish an indemnity bond sufficient in the judgment of the Company and the Transfer Agent to protect the Company and the Transfer Agent from any loss which either of them may suffer if a

31

Preferred Stock certificate is replaced. The Company and the Transfer Agent may charge the Holder for their expenses in replacing a Preferred Stock certificate.

(e) Temporary Certificates. Until definitive Preferred Stock certificates are ready for delivery, the Company may prepare and the Transfer Agent shall countersign temporary Preferred Stock certificates. Temporary Preferred Stock certificates shall be substantially in the form of definitive Preferred Stock certificates but may have variations that the Company considers appropriate for temporary Preferred Stock certificates. Without unreasonable delay, the Company shall prepare and the Transfer Agent shall countersign definitive Preferred Stock certificates and deliver them in exchange for temporary Preferred Stock certificates.

(f) Cancelation. (i) In the event the Company shall purchase or otherwise acquire Certificated Preferred Stock, the same shall thereupon be delivered to the Transfer Agent for cancelation.

(ii) At such time as all beneficial interests in Global Preferred Stock have either been exchanged for Certificated Preferred Stock, converted, repurchased or canceled, such Global Preferred Stock shall thereupon be delivered to the Transfer Agent for cancelation.

(iii) The Transfer Agent and no one else shall cancel and destroy all Preferred Stock certificates surrendered for transfer, exchange, replacement or cancelation and deliver a certificate of such destruction to the Company unless the Company directs the Transfer Agent to deliver canceled Preferred Stock certificates to the Company. The Company may not issue new Preferred Stock certificates to replace Preferred Stock certificates to the extent they evidence Preferred Stock which the Company has purchased or otherwise acquired.

12. Additional Rights of Holders. In addition to the rights provided to Holders under this Certificate of Designation, Holders shall have the rights set forth in the Registration Rights Agreement.

32

13. Other Provisions.

(1) With respect to any notice to a holder of shares of Preferred Stock required to be provided hereunder, neither failure to mail such notice, nor any defect therein or in the mailing thereof, to any particular holder shall affect the sufficiency of the notice or the validity of the proceedings referred to in such notice with respect to the other holders or affect the legality or validity of any distribution, rights, warrant, reclassification, consolidation, merger, conveyance, transfer, dissolution, liquidation or winding-up, or the vote upon any such action. Any notice which was mailed in the manner herein provided shall be conclusively presumed to have been duly given whether or not the holder receives the notice.

(2) Shares of Preferred Stock issued and reacquired will be retired and canceled promptly after reacquisition thereof and, upon compliance with the applicable requirements of Oklahoma law, have the status of authorized but unissued shares of preferred stock of the Company undesignated as to series and may with any and all other authorized but unissued shares of preferred stock of the Company be designated or redesignated and issued or reissued, as the case may be, as part of any series of preferred stock of the Corporation, except that any issuance or reissuance of shares of Preferred Stock must be in compliance with this Certificate of Designation.

(3) The shares of Preferred Stock shall be issuable only in whole shares.

(4) All notice periods referred to herein shall commence on the date of the mailing of the applicable notice.

IN WITNESS WHEREOF, the Company has caused this certificate to be signed and attested this 28th day of February, 2003.

Such dividends shall be cumulative from the most recent date as to which dividends shall have been paid or, if no dividends have been paid, from the Issue Date (whether or not in any dividend period or periods there shall be funds of the Company legally available for the payment of such dividends) and shall accrue on a day-to-day basis, whether or not earned or declared, from and after the Issue Date. Dividends payable for any partial dividend period, including the initial partial dividend period ending immediately prior to June 15, 2004, shall be computed on the basis of days elapsed over a 360-day year consisting of twelve 30-day months. Accumulations of dividends on shares of Preferred Stock shall not bear interest.

(b) If (i) by July 28, 2004, the Shelf Registration Statement has not been filed with the Commission, (ii) by November 25, 2004, the Shelf Registration Statement has not been declared effective by the Commission or (iii) after the Shelf Registration Statement has been declared effective, (A) the Shelf Registration Statement thereafter ceases to be effective or (B) the Shelf Registration Statement or the related prospectus ceases to be usable (in each case, subject to the exceptions described below) in connection with resales of Transfer Restricted Securities during the period that any Transfer Restricted Securities (other than Transfer Restricted Securities held or beneficially owned by affiliates of the Company) remain

6

outstanding (each such event referred to in clauses (i), (ii) and (iii), a “Registration Default”), additional dividends shall accrue on the Preferred Stock at the rate of .50% per annum (resulting in a Dividend Rate of 4.625% per annum during the continuance of a Registration Default), from and including the date on which any such Registration Default shall occur to but excluding the date on which all Registration Defaults have been cured. At all other times, dividends shall accumulate on the Preferred Stock at the Dividend Rate as described in Section 3(a).

A Registration Default referred to in clause (iii) of Section 3(b) shall be deemed not to have occurred and be continuing in relation to the Shelf Registration Statement or the related prospectus if (i) such Registration Default has occurred solely as a result of (x) the filing of a post-effective amendment to the Shelf Registration Statement to incorporate annual audited financial information with respect to the Company where such post-effective amendment is not yet effective and needs to be declared effective to permit Holders to use the related prospectus or (y) other material events, with respect to the Company that would need to be described in the Shelf Registration Statement or the related prospectus and (ii) in the case of clause (y), the Company is proceeding promptly and in good faith to amend or supplement such Shelf Registration Statement and related prospectus to describe such events; provided, however, that in any case if such Registration Default referred to in clause (iii) of Section 3(b) occurs for a continuous period in excess of 30 days, additional dividends as described in Section 3(b) shall be payable in accordance therewith from the day such Registration Default occurs until such Registration Default is cured.

(c) No dividend will be declared or paid upon, or any sum set apart for the payment of dividends upon, any outstanding share of the Preferred Stock with respect to any dividend period unless all dividends for all preceding dividend periods have been declared and paid or declared and a sufficient sum set apart for the payment of such dividend, upon all outstanding shares of Preferred Stock.

(d) No dividends or other distributions (other than a dividend or distribution payable solely in shares of Parity Stock or Junior Stock (in the case of Parity Stock) or Junior Stock (in the case of Junior Stock) and other than cash paid in lieu of fractional shares) may be declared, made or paid, or set apart for payment upon, any Parity Stock or Junior Stock, nor may any Parity Stock or Junior Stock be redeemed, purchased or otherwise acquired for any consideration (or any money paid to or made available for a sinking fund for the redemption of any Parity Stock or Junior Stock) by or on behalf of the Company (except by conversion into or exchange for shares of Parity Stock or Junior Stock (in the case of Parity Stock) or Junior Stock (in the case of Junior Stock)), unless full Accumulated Dividends shall have been or contemporaneously are declared and paid, or are declared and a sum sufficient for the payment thereof is set apart for such payment, on the Preferred Stock and any Parity Stock for all dividend payment periods terminating on or prior to the date of such declaration, payment, redemption, purchase or acquisition. Notwithstanding the foregoing, if full dividends have not been paid on the Preferred Stock and any Parity Stock, dividends may be declared and paid on the Preferred Stock and such Parity Stock so long as the dividends are declared and paid pro rata so that the amounts of dividends declared per share on the Preferred Stock and such Parity Stock will in all cases bear to each other the same ratio that accumulated and unpaid dividends per share on the shares of Preferred Stock and such other Parity Stock bear to each other.

7

(e) Holders of shares of Preferred Stock shall not be entitled to any dividends on the Preferred Stock, whether payable in cash, property or stock, in excess of full cumulative dividends. No interest, or sum of money in lieu of interest, shall be payable in respect of any dividend payment or payments on the Preferred Stock which may be in arrears.

(f) The holders of shares of Preferred Stock at the close of business on a Dividend Record Date will be entitled to receive the dividend payment on those shares on the next following Dividend Payment Date notwithstanding the subsequent conversion thereof or the Company’s default in payment of the dividend due on that Dividend Payment Date. However, shares of Preferred Stock surrendered for conversion during the period between the close of business on any Dividend Record Date and the close of business on the Business Day immediately preceding the applicable Dividend Payment Date must be accompanied by payment of an amount equal to the dividend payable on the shares on that Dividend Payment Date. A holder of shares of Preferred Stock on a Dividend Record Date who (or whose transferee) tenders any shares for conversion on the corresponding Dividend Payment Date will receive the dividend payable by the Company on the Preferred Stock on that date, and the converting holder need not include payment in the amount of such dividend upon surrender of shares of Preferred Stock for conversion. Except as provided above with respect to a voluntary conversion pursuant to Section 7, the Company shall make no payment or allowance for unpaid dividends, whether or not in arrears, on converted shares or for dividends on the shares of Common Stock issued upon conversion.

4. Change of Control.

(a) Upon the occurrence of a Change of Control, each holder of Preferred Stock shall, in the event that the Market Value for the period ending on the Change of Control Date is less than the Conversion Price, have a one-time option (the “Change of Control Option”) to convert all of such holder’s outstanding shares of Preferred Stock into fully paid and nonassessable shares of Common Stock at an adjusted Conversion Price equal to the greater of (i) the Market Value for the period ending on the Change of Control Date and (ii) $8.0733. The Change of Control Option must be exercised, if at all, during the period of not less than 30 days nor more than 60 days commencing on the third Business Day after notice of a Change in Control has been given by the Company in accordance with Section 4(b). In lieu of issuing the shares of Common Stock issuable upon conversion in the event of a Change of Control, the Company may, at its option, make a cash payment equal to the Market Value for each share of such Common Stock otherwise issuable determined for the period ending on the Change of Control Date. Notwithstanding the foregoing, upon the occurrence of a Change of Control in which (i) each holder of Common Stock receives consideration consisting solely of common stock of the successor, acquiror or other third party (and cash paid in lieu of fractional shares) that is listed on a national securities exchange or quoted on the NASDAQ National Market and (ii) all the Common Stock has been exchanged for, converted into or acquired for common stock of the successor, acquiror or other third party (and cash in lieu of factional shares), and the Preferred Stock becomes convertible solely into such common stock, the Conversion Price will not be adjusted as described in this Section 4(a).

(b) In the event of a Change of Control (other than a Change of Control described in the last sentence of Section 4(a)), notice of such Change of Control shall be given,

8

within five Business Days of the Change of Control Date, by the Company by first-class mail to each record holder of shares of Preferred Stock, at such holder’s address as the same appears on the books of the Company. Each such notice shall state (i) that a Change of Control has occurred; (ii) the last day on which the Change of Control Option may be exercised (the “Expiration Date”) pursuant to the terms hereof; (iii) the name and address of the Transfer Agent; and (iv) the procedures that holders must follow to exercise the Change of Control Option.

(c) On or before the Expiration Date, each holder of shares of Preferred Stock wishing to exercise the Change of Control Option shall surrender the certificate or certificates representing the shares of Preferred Stock to be converted, in the manner and at the place designated in the notice described in Section 4(b), and on such date the cash or shares of Common Stock due to such holder shall be delivered to the Person whose name appears on such certificate or certificates as the owner thereof and the shares represented by each surrendered certificate shall be returned to authorized but unissued shares. Upon surrender (in accordance with the notice described in Section 4(b)) of the certificate or certificates representing any shares to be so converted (properly endorsed or assigned for transfer, if the Company shall so require and the notice shall so state), such shares shall be converted by the Company at the adjusted Conversion Price, if applicable, as described in Section 4(a).

(d) The rights of holders of Preferred Stock pursuant to this Section 4 are in addition to, and not in lieu of, the rights of holders of Preferred Stock provided for in Section 7 hereof.

5. Voting.

(a) The shares of Preferred Stock shall have no voting rights except as set forth below or as otherwise required by Oklahoma law from time to time:

(i) If and whenever at any time or times a Voting Rights Triggering Event occurs, then the holders of shares of Preferred Stock, voting as a single class with any other preferred stock or preference securities having similar voting rights that are exercisable, including the 5.00% Preferred Stock, the 6.00% Preferred Stock and the 6.75% Preferred Stock (the “Voting Rights Class”), will be entitled at the next regular or special meeting of stockholders of the Company to elect two additional directors of the Company. Upon the election of any such additional directors, the number of directors that comprise the Board of Directors shall be increased by such number of additional directors.

(ii) Such voting rights may be exercised at a special meeting of the holders of the shares of the Voting Rights Class, called as hereinafter provided, or at any annual meeting of stockholders held for the purpose of electing directors, and thereafter at each such annual meeting until such time as all dividends in arrears on the shares of Preferred Stock shall have been paid in full, at which time or times such voting rights and the term of the directors elected pursuant to Section 5(a)(i) shall terminate.

(iii) At any time when such voting rights shall have vested in holders of shares of the Voting Rights Class, an Officer of the Company may call, and, upon

9

written request of the record holders of shares representing at least twenty-five percent (25%) of the voting power of the shares then outstanding of the Voting Rights Class, addressed to the Secretary of the Company, shall call a special meeting of the holders of shares of the Voting Rights Class. Such meeting shall be held at the earliest practicable date upon the notice required for annual meetings of stockholders at the place for holding annual meetings of stockholders of the Company, or, if none, at a place designated by the Board of Directors. Notwithstanding the provisions of this Section 5(a)(iii), no such special meeting shall be called during a period within the 60 days immediately preceding the date fixed for the next annual meeting of stockholders in which such case, the election of directors pursuant to Section 5(a)(i) shall be held at such annual meeting of stockholders.

(iv) At any meeting held for the purpose of electing directors at which the holders of the Voting Rights Class shall have the right to elect directors as provided herein, the presence in person or by proxy of the holders of shares representing more than fifty percent (50%) in voting power of the then outstanding shares of the Voting Rights Class shall be required and shall be sufficient to constitute a quorum of such class for the election of directors by such class. The affirmative vote of the holders of shares of Preferred Stock constituting a majority of the shares of Preferred Stock present at such meeting, in person or by proxy, shall be sufficient to elect any such director.

(v) Any director elected pursuant to the voting rights created under this Section 5(a) shall hold office until the next annual meeting of stockholders (unless such term has previously terminated pursuant to Section 5(a)(ii) ) and any vacancy in respect of any such director shall be filled only by vote of the remaining director so elected by holders of the Voting Rights Class, or if there be no such remaining director, by the holders of shares of the Voting Rights Class at a special meeting called in accordance with the procedures set forth in this Section 5, or, if no such special meeting is called, at the next annual meeting of stockholders. Upon any termination of such voting rights, the term of office of all directors elected pursuant to this Section 5 shall terminate.

(vi) So long as any shares of Preferred Stock remain outstanding, unless a greater percentage shall then be required by law, the Company shall not, without the affirmative vote or consent of the holders of at least 66 2/3% of the outstanding Preferred Stock voting or consenting, as the case may be, separately as one class, (i) create, authorize or issue any class or series of Senior Stock (or any security convertible into Senior Stock) or (ii) amend the Certificate of Incorporation so as to affect adversely the specified rights, preferences, privileges or voting rights of holders of shares of Preferred Stock.

(vii) In exercising the voting rights set forth in this Section 5(a), each share of Preferred Stock shall be entitled to one vote.

(b) The Company may authorize, increase the authorized amount of, or issue any class or series of Parity Stock or Junior Stock, without the consent of the holders of Preferred Stock, and in taking such actions the Company shall not be deemed to have affected adversely the rights, preferences, privileges or voting rights of holders of shares of Preferred Stock.

10

6. Liquidation Rights.

(a) In the event of any liquidation, winding-up or dissolution of the Company, whether voluntary of involuntary, each holder of shares of Preferred Stock shall be entitled to receive and to be paid out of the assets of the Company available for distribution to its stockholders the Liquidation Preference plus Accumulated Dividends and Accrued Dividends thereon in preference to the holders of, and before any payment or distribution is made on, any Junior Stock, including, without limitation, on any Common Stock.

(b) Neither the sale, conveyance, exchange or transfer (for cash, shares of stock, securities or other consideration) of all or substantially all the assets or business of the Company (other than in connection with the liquidation, winding-up or dissolution of its business) nor the merger or consolidation of the Company into or with any other Person shall be deemed to be a liquidation, winding-up or dissolution, voluntary or involuntary, for the purposes of this Section 6.

(c) After the payment to the holders of the shares of Preferred Stock of full preferential amounts provided for in this Section 6, the holders of Preferred Stock as such shall have no right or claim to any of the remaining assets of the Company.

(d) In the event the assets of the Company available for distribution to the holders of shares of Preferred Stock upon any liquidation, winding-up or dissolution of the Company, whether voluntary or involuntary, shall be insufficient to pay in full all amounts to which such holders are entitled pursuant to Section 6(a), no such distribution shall be made on account of any shares of Parity Stock upon such liquidation, dissolution or winding-up unless proportionate distributable amounts shall be paid on account of the shares of Preferred Stock, ratably, in proportion to the full distributable amounts for which holders of all Preferred Stock and of any Parity Stock are entitled upon such liquidation, winding-up or dissolution.

7. Conversion.

(a) Each holder of Preferred Stock shall have the right, only on or after the occurrence of the conversion triggering events described in Section 7(b), at its option, from the Issue Date to convert, subject to the terms and provisions of this Section 7, any or all of such holder’s shares of Preferred Stock. In such case, the shares of Preferred Stock shall be converted into such whole number of fully paid and nonassessable shares of Common Stock as is equal, subject to Section 7(h), to the product of the number of shares of Preferred Stock being so converted multiplied by the quotient of (i) the Liquidation Preference divided by (ii) the Conversion Price (as defined below) then in effect. The Conversion Price initially shall be $16.6513, subject to adjustment as set forth in Section 7(d).

The conversion right of a holder of Preferred Stock shall be exercised by the holder by the surrender to the Company of the certificates representing shares to be converted at any time during usual business hours at its principal place of business or the offices of its duly appointed Transfer Agent to be maintained by it, accompanied by written notice to the Company in the form of Exhibit B that the holder elects to convert all or a portion of the shares of Preferred Stock represented by such certificate and specifying the name or names (with address) in which a

11

certificate or certificates for shares of Common Stock are to be issued and (if so required by the Company or its duly appointed Transfer Agent) by a written instrument or instruments of transfer in form reasonably satisfactory to the Company or its duly appointed Transfer Agent duly executed by the holder or its duly authorized legal representative and transfer tax stamps or funds therefor, if required pursuant to Section 7(j). Immediately prior to the close of business on the date of receipt by the Company or its duly appointed Transfer Agent of notice of conversion of shares of Preferred Stock, each converting holder of Preferred Stock shall be deemed to be the holder of record of Common Stock issuable upon conversion of such holder’s Preferred Stock notwithstanding that the share register of the Company shall then be closed or that certificates representing such Common Stock shall not then be actually delivered to such holder. On the date of any conversion, all rights with respect to the shares of Preferred Stock so converted, including the rights, if any, to receive notices, will terminate, except only the rights of holders thereof to (i) receive certificates for the number of whole shares of Common Stock into which such shares of Preferred Stock have been converted and cash, in lieu of any fractional shares as provided in Section 7(g); and (ii) exercise the rights to which they are entitled as holders of Common Stock.

(b) A holder’s right to convert its shares of Preferred Stock will arise only upon the occurrence of the following events:

(i) Conversion Rights Based on Common Share Price. A holder may surrender shares of Preferred Stock for conversion into shares of Common Stock during any fiscal quarter after the fiscal quarter ending June 30, 2004 (and only during such fiscal quarter) if the Closing Sale Price of Common Stock for at least 20 Trading Days in a period of 30 consecutive Trading Days ending on the last Trading Day of the immediately preceding fiscal quarter is more than 130% of the Conversion Price on such Trading Day. If this Closing Sale Price condition is not satisfied at the end of any fiscal quarter, then conversion pursuant to this Section 7(b)(i) will not be permitted in the following fiscal quarter. The Company shall determine for each Trading Day during the 30 consecutive Trading Day period specified in this Section 7(b)(i) whether the Closing Sale Price exceeds 130% of the Conversion Price and whether the Preferred Stock shall be convertible as a result of the occurrence of the event set forth in this Section 7(b)(i).

(ii) Conversion Upon Satisfaction of Trading Price Condition. A holder may surrender its shares of Preferred Stock for conversion into Common Stock during the five business day period after any five consecutive Trading Day period in which the Trading Price of the Preferred Stock for each day of such five Trading Day period was less than 98% of the product of the Closing Sale Price of the Common Stock and the Conversion Price in effect on each such day. The Company shall determine whether the Preferred Stock may be converted pursuant to this Section 7(b)(ii) based on Trading Prices obtained from three independent nationally known securities dealers. The Company shall have no obligation to determine the Trading Price unless a holder of Preferred Stock provides it with reasonable evidence that the Trading Price was less than 98% of the product of the Closing Sale Price and the then-current Conversion Price. If such evidence is provided, the Company shall determine the Trading Price of the Preferred Stock beginning on the next Trading Day and on each successive Trading Day until the Trading Price is greater than or equal to 98% of the product of the Closing Sale Price and the then current Conversion Price.

12

(iii) Conversion Rights Upon Occurrence of Certain Corporate Transactions.

(1) If the Company is party to a consolidation, merger, binding share exchange or sale of all or substantially all of the Company’s assets, in each case pursuant to which the Common Stock would be converted into cash, securities or other property, a holder may surrender its shares of Preferred Stock for conversion into Common Stock at any time from and after the date that is 15 days prior to the anticipated effective date of the transaction until 15 days after the actual date of such transaction and, at the effective time, the right to convert shares of Preferred Stock into Common Stock will be changed into a right to convert such Preferred Stock into the kind and amount of cash, securities or other property of the Company or another person that the holder would have received if the holder had converted the holder’s Preferred Stock immediately prior to the transaction.

(2) If the Company elects to (A) distribute to all holders of Common Stock rights or warrants entitling them to purchase, for a period expiring within 45 days of the record date for such distribution, Common Stock at less than the average Closing Sale Price for the ten consecutive Trading Days immediately preceding the declaration date for such distribution or (B) distribute to all holders of Common Stock, cash, assets, debt securities or rights to purchase the Company’s securities, which distribution has a per share value exceeding 5% of the Closing Sale Price of Common Stock on the Trading Day immediately preceding the declaration date for such distribution; then, in either case, the Company must notify holders of Preferred Stock at least 20 days prior to the ex-dividend date for such distribution. Once the Company has given such notice, a holder may surrender its shares of Preferred Stock for conversion at any time until the earlier of the close of business on the business day immediately preceding the ex-dividend date or any announcement by the Company that such distribution will not take place. Notwithstanding the foregoing, holders shall not have the right to surrender shares of Preferred Stock for conversion pursuant to this Section 7(b)(iii)(2), and no adjustment to the Conversion Price will be made, if all holders of the Preferred Stock will otherwise participate, on the same basis as a holder of Common Shares, in the distribution described above without first converting Preferred Stock into Common Shares.

(iv) Upon a Change of Control, holders of Preferred Stock shall, if the Market Value at such time is less than the Conversion Price, have a one-time option to convert all of their outstanding shares of Preferred Stock into Common Stock pursuant to Section 4.

(v) Upon determination that holders of Preferred Stock are or will be entitled to convert their Preferred Stock into Common Stock in accordance with any of the provisions of this Section 7(b), the Company will issue a press release and publish such information on its website on the World Wide Web.

(c) If the last day for the exercise of the conversion right shall not be a Business Day, then such conversion right may be exercised on the next preceding Business Day.

(d) The Conversion Price shall be subject to adjustment as follows:

13

(i) In case the Company shall at any time or from time to time (A) pay a dividend (or other distribution) payable in shares of Common Stock on any class of capital stock (which, for purposes of this Section 7(d) shall include, without limitation, any dividends or distributions in the form of options, warrants or other rights to acquire capital stock) of the Company (other than the issuance of shares of Common Stock in connection with the conversion of preferred stock); (B) subdivide the outstanding shares of Common Stock into a larger number of shares; (C) combine the outstanding shares of Common Stock into a smaller number of shares; (D) issue any shares of its capital stock in a reclassification of the Common Stock; or (E) pay a dividend or make a distribution to all holders of shares of Common Stock (other than a dividend or distribution subject to Section 7(d)(ii)) pursuant to a stockholder rights plan, “poison pill” or similar arrangement and excluding dividends payable on the Preferred Stock then, and in each such case, the Conversion Price in effect immediately prior to such event shall be adjusted (and any other appropriate actions shall be taken by the Company) so that the holder of any share of Preferred Stock thereafter surrendered for conversion shall be entitled to receive the number of shares of Common Stock that such holder would have owned or would have been entitled to receive upon or by reason of any of the events described above, had such share of Preferred Stock been converted into shares of Common Stock immediately prior to the occurrence of such event. An adjustment made pursuant to this Section 7(d)(i) shall become effective retroactively (x) in the case of any such dividend or distribution, to the day immediately following the close of business on the record date for the determination of holders of Common Stock entitled to receive such dividend or distribution or (y) in the case of any such subdivision, combination or reclassification, to the close of business on the day upon which such corporate action becomes effective.

(ii) In case the Company shall at any time or from time to time issue to all holders of its Common Stock rights, options or warrants entitling the holders thereof to subscribe for or purchase shares of Common Stock (or securities convertible into or exchangeable for shares of Common Stock) at a price per share less than the Market Value for the period ending on the date of issuance (treating the price per share of any security convertible or exchangeable or exercisable into Common Stock as equal to (A) the sum of the price paid to acquire such security convertible, exchangeable or exercisable into Common Stock plus any additional consideration payable (without regard to any anti-dilution adjustments) upon the conversion, exchange or exercise of such security into Common Stock divided by (B) the number of shares of Common Stock into which such convertible, exchangeable or exercisable security is initially convertible, exchangeable or exercisable), other than (i) issuances of such rights, options or warrants if the holder of Preferred Stock would be entitled to receive such rights, options or warrants upon conversion at any time of shares of Preferred Stock into Common Stock and (ii) issuances that are subject to certain triggering events (until such time as such triggering events occur), then, and in each such case, the Conversion Price then in effect shall be adjusted by dividing the Conversion Price in effect on the day immediately prior to the record date of such issuance by a fraction (y) the numerator of which shall be the sum of the number of shares of Common Stock outstanding on such record date plus the number of additional shares of Common Stock issued or to be issued upon or as a result of the issuance of such rights, options or warrants (or the maximum number into or for which such convertible or exchangeable securities initially may convert or exchange or for which such options, warrants or other rights initially may be exercised) and (z) the denominator of which shall be the sum of the number of shares of Common Stock outstanding on such record date plus the number of shares

14

of Common Stock which the aggregate consideration for the total number of such additional shares of Common Stock so issued (or into or for which such convertible or exchangeable securities may convert or exchange or for which such options, warrants or other rights may be exercised plus the aggregate amount of any additional consideration initially payable upon the conversion, exchange or exercise of such security) would purchase at the Market Value for the period ending on the date of conversion; provided, that if the Company distributes rights or warrants (other than those referred to above in this subparagraph (d)(ii)) pro rata to the holders of Common Stock, so long as such rights or warrants have not expired or been redeemed by the Company, (y) the holder of any Preferred Stock surrendered for conversion shall be entitled to receive upon such conversion, in addition to the shares of Common Stock then issuable upon such conversion (the “Conversion Shares”), a number of rights or warrants to be determined as follows: (i) if such conversion occurs on or prior to the date for the distribution to the holders of rights or warrants of separate certificates evidencing such rights or warrants (the “Distribution Date”), the same number of rights or warrants to which a holder of a number of shares of Common Stock equal to the number of Conversion Shares is entitled at the time of such conversion in accordance with the terms and provisions applicable to the rights or warrants and (ii) if such conversion occurs after the Distribution Date, the same number of rights or warrants to which a holder of the number of shares of Common Stock into which such Preferred Stock was convertible immediately prior to such Distribution Date would have been entitled on such Distribution Date had such Preferred Stock been converted immediately prior to such Distribution Date in accordance with the terms and provisions applicable to the rights and warrants and (z) the Conversion Price shall not be subject to adjustment on account of any declaration, distribution or exercise of such rights or warrants.

(iii) If the Company shall at any time make a distribution, by dividend or otherwise, to all holders of shares of its Common Stock consisting exclusively of cash (excluding any cash portion of distributions referred to in clause (E) of paragraph (d)(i) above and cash distributed upon a merger or consolidation to which paragraph (h) below applies) in an amount per share of Common Stock that, when combined with the per share amounts of all other all-cash distributions to all holders of shares of its Common Stock made within the 90-day period ending on the record date for the distribution giving rise to an adjustment pursuant to this Section 7(d)(iii), exceeds $0.055 per share of Common Stock (the “Distribution Threshold Amount”), then the Conversion Price will be adjusted by multiplying:

(1) the Conversion Price in effect immediately prior to the close of business on the record date fixed for the determination of holders of Common Stock entitled to receive such distribution by

(2) a fraction, the numerator of which will be the Market Value on the fourth trading day on the NYSE prior to such record date minus the amount of cash per share of Common Stock so distributed in excess of the Dividend Threshold Amount for which an adjustment has not otherwise been made pursuant to this Section 7(d)(iii) and the denominator of which will be the Market Value on the fourth trading day on the NYSE prior to such record date.

Subject to Section 7(e), such adjustment shall become effective immediately after the record date for the determination of holders of Common Stock entitled to receive the distribution giving rise to an adjustment pursuant to this Section 7(d)(iii). The Dividend

15

Threshold Amount is subject to adjustment under the same circumstances under which the Conversion Price is subject to adjustment pursuant to Section 7(d)(i) or Section 7(d)(ii).

(iv) In the case the Company at any time or from time to time shall take any action affecting its Common Stock (it being understood that the issuance or sale of shares of Common Stock (or securities convertible into or exchangeable for shares of Common Stock, or any options, warrants or other rights to acquire shares of Common Stock) to any Person at a price per share less than the Conversion Price then in effect shall not be deemed such an action), other than an action described in any of Section 7(d)(i) through Section 7(d)(iii), inclusive, or Section 7(h), then the Conversion Price shall be adjusted in such manner and at such time as the Board of Directors of the Company in good faith determines to be equitable in the circumstances (such determination to be evidenced in a resolution, a certified copy of which shall be mailed to the holders of the Preferred Stock).

(v) Notwithstanding anything herein to the contrary, no adjustment under this Section 7(d) need be made to the Conversion Price unless such adjustment would require an increase or decrease of at least 1% of the Conversion Price then in effect. Any lesser adjustment shall be carried forward and shall be made at the time of and together with the next subsequent adjustment, if any, which, together with any adjustment or adjustments so carried forward, shall amount to an increase or decrease of at least 1% of such Conversion; provided, however, that with respect to adjustments to be made to the Conversion Price in connection with cash dividends paid by the Company, the Company shall make such adjustments, regardless of whether such aggregate adjustments amount to 1% or more of the Conversion Price, no later than March 15 of each calendar year.

(vi) The Company reserves the right to make such reductions in the Conversion Price in addition to those required in the foregoing provisions as it considers advisable in order that any event treated for Federal income tax purposes as a dividend of stock or stock rights will not be taxable to the recipients. In the event the Company elects to make such a reduction in the Conversion Price, the Company will comply with the requirements of Rule 14e-1 under the Exchange Act, and any other securities laws and regulations thereunder if and to the extent that such laws and regulations are applicable in connection with the reduction of the Conversion Price.

(e) If the Company shall take a record of the holders of its Common Stock for the purpose of entitling them to receive a dividend or other distribution, and shall thereafter (and before the dividend or distribution has been paid or delivered to stockholders) legally abandon its plan to pay or deliver such dividend or distribution, then thereafter no adjustment in the Conversion Price then in effect shall be required by reason of the taking of such record.

(f) Upon any increase or decrease in the Conversion Price, then, and in each such case, the Company promptly shall deliver to each holder of Preferred Stock a certificate signed by an authorized officer of the Company, setting forth in reasonable detail the event requiring the adjustment and the method by which such adjustment was calculated and specifying the increased or decreased Conversion Price then in effect following such adjustment.

16

(g) No fractional shares or securities representing fractional shares of Common Stock shall be issued upon the conversion of any shares of Preferred Stock, whether voluntary or mandatory. If more than one share of Preferred Stock shall be surrendered for conversion at one time by the same holder, the number of full shares of Common Stock issuable upon conversion thereof shall be computed on the basis of the aggregate Liquidation Preference of the shares of Preferred Stock so surrendered. If the conversion of any share or shares of Preferred Stock results in a fraction, an amount equal to such fraction multiplied by the last reported sale price of the Common Stock on the NYSE (or on such other national securities exchange or automated quotation system on which the Common Stock is then listed for trading or authorized for quotation or, if the Common Stock is not then so listed or authorized for quotation, an amount determined in good faith by the Board of Directors to be the fair value of the Common Stock) at the close of business on the trading day next preceding the day of conversion shall be paid to such holder in cash by the Company.

(h) In the event of any reclassification of outstanding shares of Common Stock (other than a change in par value, or from par value to no par value, or from no par value to par value), or in the event of any consolidation or merger of the Company with or into another Person or any merger of another Person with or into the Company (other than a consolidation or merger in which the Company is the resulting or surviving Person and which does not result in any reclassification or change of outstanding Common Stock), or in the event of any sale or other disposition to another Person of all or substantially all of the assets of the Company (computed on a consolidated basis) (any of the foregoing, a “Transaction”), each share of Preferred Stock then outstanding shall, without the consent of any holder of Preferred Stock, become convertible at any time, at the option of the holder thereof, only into the kind and amount of securities (of the Company or another issuer), cash and other property receivable upon such Transaction by a holder of the number of shares of Common Stock into which such share of Preferred Stock could have been converted immediately prior to such Transaction, after giving effect to any adjustment event. The provisions of this Section 7(h) and any equivalent thereof in any such securities similarly shall apply to successive Transactions. The provisions of this Section 7(h) shall be the sole right of holders of Preferred Stock in connection with any Transaction and such holders shall have no separate vote thereon.

(i) The Company shall at all times reserve and keep available for issuance upon the conversion of the Preferred Stock such number of its authorized but unissued shares of Common Stock as will from time to time be sufficient to permit the conversion of all outstanding shares of Preferred Stock, and shall take all action required to increase the authorized number of shares of Common Stock if at any time there shall be insufficient unissued shares of Common Stock to permit such reservation or to permit the conversion of all outstanding shares of Preferred Stock.

(j) The issuance or delivery of certificates for Common Stock upon the conversion of shares of Preferred Stock shall be made without charge to the converting holder of shares of Preferred Stock for such certificates or for any tax in respect of the issuance or delivery of such certificates or the securities represented thereby, and such certificates shall be issued or delivered in the respective names of, or in such names as may be directed by, the holders of the shares of Preferred Stock converted; provided, however, that the Company shall not be required to pay any tax which may be payable in respect of any transfer involved in the issuance and

17

delivery of any such certificate in a name other than that of the holder of the shares of Preferred Stock converted, and the Company shall not be required to issue or deliver such certificate unless or until the Person or Persons requesting the issuance or delivery thereof shall have paid to the Company the amount of such tax or shall have established to the reasonable satisfaction of the Company that such tax has been paid.

8. Mandatory Conversion.

(a) At any time on or after March 15, 2009, the Company shall have the right, at its option, to cause the Preferred Stock, in whole but not in part, to be automatically converted into that number of whole shares of Common Stock for each share of Preferred Stock equal to the quotient of (i) the Liquidation Preference divided by (ii) the Conversion Price then in effect, with any resulting fractional shares of Common Stock to be settled in accordance with Section 7(g). The Company may exercise its right to cause a mandatory conversion pursuant to this Section 8(a) only if the closing price of the Common Stock equals or exceeds 130% of the Conversion Price then in effect for at least 20 trading days in any consecutive 30-day trading period on the NYSE (or such other national securities exchange or automated quotation system on which the Common Stock is then listed or authorized for quotation), including the last trading day of such 30-day period, ending on the trading day prior to the Company’s issuance of a press release announcing the mandatory conversion as described in Section 8(b).

(b) To exercise the mandatory conversion right described in Section 8(a), the Company must issue a press release for publication on the Dow Jones News Service prior to the opening of business on the first trading day following any date on which the conditions described in Section 8(a) are met, announcing such a mandatory conversion. The Company shall also give notice by mail or by publication (with subsequent prompt notice by mail) to the holders of Preferred Stock (not more than four Business Days after the date of the press release) of the mandatory conversion announcing the Company’s intention to convert the Preferred Stock. The conversion date will be a date selected by the Company (the “Mandatory Conversion Date”) and will be no more than five days after the date on which the Company issues the press release described in this Section 8(b).

(c) In addition to any information required by applicable law or regulation, the press release and notice of a mandatory conversion described in Section 8(b) shall state, as appropriate: (i) the Mandatory Conversion Date; (ii) the number of shares of Common Stock to be issued upon conversion of each share of Preferred Stock; (iii) the number of shares of Preferred Stock to be converted; and (iv) that dividends on the Preferred Stock to be converted will cease to accrue on the Mandatory Conversion Date.

(d) On and after the Mandatory Conversion Date, dividends will cease to accrue on the Preferred Stock called for a mandatory conversion pursuant to Section 8(a) and all rights of holders of such Preferred Stock will terminate except for the right to receive the whole shares of Common Stock issuable upon conversion thereof and cash, in lieu of any fractional shares of Common Stock in accordance with Section 7(g). The dividend payment with respect to the Preferred Stock called for a mandatory conversion pursuant to Section 8(a) on a date during the period between the close of business on any Dividend Record Date to the close of business on the corresponding Dividend Payment Date will be payable on such Dividend Payment Date to

18

the record holder of such share on such Dividend Record Date if such share has been converted after such Dividend Record Date and prior to such Dividend Payment Date. Except as provided in the immediately preceding sentence with respect to a mandatory conversion pursuant to Section 8(a), no payment or adjustment will be made upon conversion of Preferred Stock for Accrued Dividends or for dividends with respect to the Common Stock issued upon such conversion.

(e) The Company may not authorize, issue a press release or give notice of any mandatory conversion pursuant to Section 8(a) unless, prior to giving the conversion notice, all Accumulated Dividends on the Preferred Stock for periods ended prior to the date of such conversion notice shall have been paid in cash.

(f) In addition to the mandatory conversion right described in Section 8(a), if there are less than 25,000 shares of Preferred Stock outstanding, the Company shall have the right, at any time on or after March 15, 2009, at its option, to cause the Preferred Stock to be automatically converted into that number of whole shares of Common Stock equal to the quotient of (i) the Liquidation Preference divided by (ii) the lesser of (A) the Conversion Price then in effect and (B) the Market Value for the period ending on the second trading day immediately prior to the Mandatory Conversion Date, with any resulting fractional shares of Common Stock to be settled in cash in accordance with Section 7(g). The provisions of clauses (b), (c), (d) and (e) of this Section 8 shall apply to any mandatory conversion pursuant to this clause (f); provided that (i) the Mandatory Conversion Date described in Section 8(b) shall not be less than 15 days nor more than 30 days after the date on which the Company issues a press release pursuant to Section 8(b) announcing such mandatory conversion and (ii) the press release and notice of mandatory conversion described in Section 8(c) will not state the number of shares of Common Stock to be issued upon conversion of each share of Preferred Stock.

9. Consolidation, Merger and Sale of Assets.

(a) The Company, without the consent of the holders of any of the outstanding Preferred Stock, may consolidate with or merge into any other Person or convey, transfer or lease all or substantially all its assets to any Person or may permit any Person to consolidate with or merge into, or transfer or lease all or substantially all its properties to, the Company; provided, however, that (a) the successor, transferee or lessee is organized under the laws of the United States or any political subdivision thereof; (b) the shares of Preferred Stock will become shares of such successor, transferee or lessee, having in respect of such successor, transferee or lessee the same powers, preferences and relative participating, optional or other special rights and the qualification, limitations or restrictions thereon, the Preferred Stock had immediately prior to such transaction; and (c) the Company delivers to the Transfer Agent an Officers’ Certificate and an Opinion of Counsel stating that such transaction complies with this Certificate of Designation.

(b) Upon any consolidation by the Company with, or merger by the Company into, any other person or any conveyance, transfer or lease of all or substantially all the assets of the Company as described in Section 9(a), the successor resulting from such consolidation or into which the Company is merged or the transferee or lessee to which such conveyance, transfer or lease is made, will succeed to, and be substituted for, and may exercise every right and power

19

of, the Company under the shares of Preferred Stock, and thereafter, except in the case of a lease, the predecessor (if still in existence) will be released from its obligations and covenants with respect to the Preferred Stock.

10. SEC Reports.

Whether or not the Company is required to file reports with the Commission, if any shares of Preferred Stock are outstanding, the Company shall file with the Commission all such reports and other information as it would be required to file with the Commission by Section 13(a)or 15(d) under the Exchange Act. The Company shall supply each holder of Preferred Stock, upon request, without cost to such holder, copies of such reports or other information.

11. Certificates.

(a) Form and Dating. The Preferred Stock and the Transfer Agent’s certificate of authentication shall be substantially in the form set forth in Exhibit A, which is hereby incorporated in and expressly made a part of this Certificate of Designation. The Preferred Stock certificate may have notations, legends or endorsements required by law, stock exchange rule, agreements to which the Company is subject, if any, or usage (provided that any such notation, legend or endorsement is in a form acceptable to the Company). Each Preferred Stock certificate shall be dated the date of its authentication. The terms of the Preferred Stock certificate set forth in Exhibit A are part of the terms of this Certificate of Designation.

(i) Global Preferred Stock. The Preferred Stock shall be issued initially in the form of one or more fully registered global certificates with the global securities legend and restricted securities legend set forth in Exhibit A hereto (the “Global Preferred Stock”), which shall be deposited on behalf of the purchasers represented thereby with the Transfer Agent, as custodian for DTC (or with such other custodian as DTC may direct), and registered in the name of DTC or a nominee of DTC, duly executed by the Company and authenticated by the Transfer Agent as hereinafter provided. The number of shares of Preferred Stock represented by Global Preferred Stock may from time to time be increased or decreased by adjustments made on the records of the Transfer Agent and DTC or its nominee as hereinafter provided. With respect to shares of Preferred Stock that are not “restricted securities” as defined in Rule 144 on a conversion date, all shares of Common Stock distributed on such conversion date will be freely transferable without restriction under the Securities Act (other than by affiliates), and such shares will be eligible for receipt in global form through the facilities of DTC.

(ii) Book-Entry Provisions. In the event Global Preferred Stock is deposited with or on behalf of DTC, the Company shall execute and the Transfer Agent shall authenticate and deliver initially one or more Global Preferred Stock certificates that (a) shall be registered in the name of DTC as depository for such Global Preferred Stock or the nominee of DTC and (b) shall be delivered by the Transfer Agent to DTC or pursuant to DTC’s instructions or held by the Transfer Agent as custodian for DTC.

20

Members of, or participants in, DTC (“Agent Members”) shall have no rights under this Certificate of Designation with respect to any Global Preferred Stock held on their behalf by DTC or by the Transfer Agent as the custodian of DTC or under such Global Preferred Stock, and DTC may be treated by the Company, the Transfer Agent and any agent of the Company or the Transfer Agent as the absolute owner of such Global Preferred Stock for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Transfer Agent or any agent of the Company or the Transfer Agent from giving effect to any written certification, proxy or other authorization furnished by DTC or impair, as between DTC and its Agent Members, the operation of customary practices of DTC governing the exercise of the rights of a holder of a beneficial interest in any Global Preferred Stock.

(iii) Certificated Preferred Stock; Certificated Common Stock. Except as provided in this paragraph 11(a) or in paragraph 11(c), owners of beneficial interests in Global Preferred Stock will not be entitled to receive physical delivery of Preferred Stock in fully registered certificated form (“Certificated Preferred Stock”). With respect to shares of Preferred Stock that are “restricted securities” as defined in Rule 144 on a conversion date, all shares of Common Stock issuable on conversion of such shares on such conversion date will be issued in fully registered certificated form (“Certificated Common Stock”). Certificates of Certificated Common Stock will be mailed or made available at the office of the Transfer Agent for the Preferred Stock on or as soon as reasonably practicable after the relevant conversion date to the converting holder.

After a transfer of any Preferred Stock or Certificated Common Stock during the period of the effectiveness of a Shelf Registration Statement with respect to such Preferred Stock or such Certificated Common Stock, all requirements pertaining to legends on such Preferred Stock (including Global Preferred Stock) or Certificated Common Stock will cease to apply, the requirements requiring that any such Certificated Common Stock issued to Holders be issued in certificated form, as the case may, will cease to apply, and Preferred Stock or Common Stock, as the case may be, in global or fully registered certificated form, in either case without legends, will be available to the transferee of the Holder of such Preferred Stock or Certificated Common Stock upon exchange of such transferring Holder’s Preferred Stock or Common Stock or directions to transfer such Holder’s interest in the Global Preferred Stock, as applicable.

(b) Execution and Authentication. Two Officers shall sign the Preferred Stock certificate for the Company by manual or facsimile signature.

If an Officer whose signature is on a Preferred Stock certificate no longer holds that office at the time the Transfer Agent authenticates the Preferred Stock certificate, the Preferred Stock certificate shall be valid nevertheless.

A Preferred Stock certificate shall not be valid until an authorized signatory of the Transfer Agent manually signs the certificate of authentication on the Preferred Stock certificate. The signature shall be conclusive evidence that the Preferred Stock certificate has been authenticated under this Certificate of Designation.

The Transfer Agent shall authenticate and deliver certificates for up to 313,250 shares of Preferred Stock for original issue upon a written order of the Company signed by two

21

Officers or by an Officer and an Assistant Treasurer of the Company. Such order shall specify the number of shares of Preferred Stock to be authenticated and the date on which the original issue of Preferred Stock is to be authenticated.

The Transfer Agent may appoint an authenticating agent reasonably acceptable to the Company to authenticate the certificates for Preferred Stock. Unless limited by the terms of such appointment, an authenticating agent may authenticate certificates for Preferred Stock whenever the Transfer Agent may do so. Each reference in this Certificate of Designation to authentication by the Transfer Agent includes authentication by such agent. An authenticating agent has the same rights as the Transfer Agent or agent for service of notices and demands.

(c) Transfer and Exchange. (i) Transfer and Exchange of Certificated Preferred Stock. When Certificated Preferred Stock is presented to the Transfer Agent with a request to register the transfer of such Certificated Preferred Stock or to exchange such Certificated Preferred Stock for an equal number of shares of Certificated Preferred Stock, the Transfer Agent shall register the transfer or make the exchange as requested if its reasonable requirements for such transaction are met; provided, however, that the Certificated Preferred Stock surrendered for transfer or exchange:

(1) shall be duly endorsed or accompanied by a written instrument of transfer in form reasonably satisfactory to the Company and the Transfer Agent, duly executed by the Holder thereof or its attorney duly authorized in writing; and

(2) is being transferred or exchanged pursuant to an effective registration statement under the Securities Act or pursuant to clause (i) or (ii) below, and is accompanied by the following additional information and documents, as applicable:

(I) if such Certificated Preferred Stock is being delivered to the Transfer Agent by a Holder for registration in the name of such Holder, without transfer, a certification from such Holder to that effect in substantially the form of Exhibit C hereto; or

(II) if such Certificated Preferred Stock is being transferred to the Company or to a “qualified institutional buyer (“QIB”) in accordance with Rule 144A under the Securities Act or pursuant to another exemption from registration under the Securities Act, (i) a certification to that effect (in substantially the form of Exhibit C hereto) and (ii) if the Company so requests, an Opinion of Counsel or other evidence reasonably satisfactory to it as to the compliance with the restrictions set forth in the legend set forth in paragraph 11(c) (vii).

(ii) Restrictions on Transfer of Certificated Preferred Stock for a Beneficial Interest in Global Preferred Stock. Certificated Preferred Stock may not be exchanged for a beneficial interest in Global Preferred Stock except upon satisfaction of the requirements set forth below. Upon receipt by the Transfer Agent of Certificated Preferred Stock, duly endorsed or accompanied by appropriate instruments of transfer, in form reasonably satisfactory to the Company and the Transfer Agent, together with written instructions directing

22

the Transfer Agent to make, or to direct DTC to make, an adjustment on its books and records with respect to such Global Preferred Stock to reflect an increase in the number of shares of Preferred Stock represented by the Global Preferred Stock, then the Transfer Agent shall cancel such Certificated Preferred Stock and cause, or direct DTC to cause, in accordance with the standing instructions and procedures existing between DTC and the Transfer Agent, the number of shares of Preferred Stock represented by the Global Preferred Stock to be increased accordingly. If no Global Preferred Stock is then outstanding, the Company shall issue and the Transfer Agent shall authenticate, upon written order of the Company in the form of an Officers’ Certificate, a new Global Preferred Stock representing the appropriate number of shares.

(iii) Transfer and Exchange of Global Preferred Stock. The transfer and exchange of Global Preferred Stock or beneficial interests therein shall be effected through DTC, in accordance with this Certificate of Designation (including applicable restrictions on transfer set forth herein, if any) and the procedures of DTC therefor.

(iv) Transfer of a Beneficial Interest in Global Preferred Stock for a Certificated Preferred Stock.

(1) Any Person having a beneficial interest in Preferred Stock that is being transferred or exchanged pursuant to an effective registration statement under the Securities Act or pursuant to another exemption from registration thereunder may upon request, but only with the consent of the Company, and if accompanied by a certification from such Person to that effect (in substantially the form of Exhibit C hereto), exchange such beneficial interest for Certificated Preferred Stock representing the same number of shares of Preferred Stock. Upon receipt by the Transfer Agent of written instructions or such other form of instructions as is customary for DTC from DTC or its nominee on behalf of any Person having a beneficial interest in Global Preferred Stock and upon receipt by the Transfer Agent of a written order or such other form of instructions as is customary for DTC or the Person designated by DTC as having such a beneficial interest in a Transfer Restricted Security only, then, the Transfer Agent or DTC, at the direction of the Transfer Agent, will cause, in accordance with the standing instructions and procedures existing between DTC and the Transfer Agent, the number of shares of Preferred Stock represented by Global Preferred Stock to be reduced on its books and records and, following such reduction, the Company will execute and the Transfer Agent will authenticate and deliver to the transferee Certificated Preferred Stock.

(2) Certificated Preferred Stock issued in exchange for a beneficial interest in a Global Preferred Stock pursuant to this paragraph 11(c)(iv) shall be registered in such names and in such authorized denominations as DTC, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Transfer Agent. The Transfer Agent shall deliver such Certificated Preferred Stock to the Persons in whose names such Preferred Stock are so registered in accordance with the instructions of DTC.

(v) Restrictions on Transfer and Exchange of Global Preferred Stock.

23

(1) Notwithstanding any other provisions of this Certificate of Designation (other than the provisions set forth in paragraph 11(c)(vi)), Global Preferred Stock may not be transferred as a whole except by DTC to a nominee of DTC or by a nominee of DTC to DTC or another nominee of DTC or by DTC or any such nominee to a successor depository or a nominee of such successor depository.

(2) In the event that the Global Preferred Stock is exchanged for Preferred Stock in definitive registered form pursuant to paragraph 11(c)(vi) prior to the effectiveness of a Shelf Registration Statement with respect to such securities, such Preferred Stock may be exchanged only in accordance with such procedures as are substantially consistent with the provisions of this paragraph 11(c) (including the certification requirements set forth in the Exhibits to this Certificate of Designation intended to ensure that such transfers comply with Rule 144A or such other applicable exemption from registration under the Securities Act, as the case may be) and such other procedures as may from time to time be adopted by the Company.

(vi) Authentication of Certificated Preferred Stock. If at any time:

(1) DTC notifies the Company that DTC is unwilling or unable to continue as depository for the Global Preferred Stock and a successor depository for the Global Preferred Stock is not appointed by the Company within 90 days after delivery of such notice;

(2) DTC ceases to be a clearing agency registered under the Exchange Act and a successor depository for the Global Preferred Stock is not appointed by the Company within 90 days; or

(3) the Company, in its sole discretion, notifies the Transfer Agent in writing that it elects to cause the issuance of Certificated Preferred Stock under this Certificate of Designation,

then the Company will execute, and the Transfer Agent, upon receipt of a written order of the Company signed by two Officers or by an Officer and an Assistant Treasurer of the Company requesting the authentication and delivery of Certificated Preferred Stock to the Persons designated by the Company, will authenticate and deliver Certificated Preferred Stock equal to the number of shares of Preferred Stock represented by the Global Preferred Stock, in exchange for such Global Preferred Stock.

(vii) Legend.

(1) Except as permitted by the following paragraph (2) and in paragraph 11(a)(iii), each certificate evidencing the Global Preferred Stock, the Certificated Preferred Stock and Certificated Common Stock shall bear a legend in substantially the following form:

“THE SECURITY EVIDENCED HEREBY (OR ITS PREDECESSOR) WAS ORIGINALLY ISSUED IN A TRANSACTION EXEMPT FROM REGISTRATION UNDER THE UNITED STATES SECURITIES ACT

24

OF 1933 (THE “SECURITIES ACT”), AND THIS SECURITY (AND THE COMMON STOCK INTO WHICH THIS SECURITY IS CONVERTIBLE) MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM. EACH PURCHASER OF THE SECURITY EVIDENCED HEREBY IS HEREBY NOTIFIED THAT THE SELLER MAY BE RELYING ON THE EXEMPTION FROM THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER. THE HOLDER OF THE SECURITY EVIDENCED HEREBY AGREES FOR THE BENEFIT OF THE COMPANY THAT (A) SUCH SECURITY (AND THE COMMON STOCK INTO WHICH THIS SECURITY IS CONVERTIBLE) MAY BE OFFERED, RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (1) IN THE UNITED STATES TO A PERSON WHO THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) PURCHASING FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A, (2) PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER (IF AVAILABLE), (3) TO THE COMPANY OR (4) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, IN EACH OF CASES (1) THROUGH (4) IN ACCORDANCE WITH ALL APPLICABLE SECURITIES LAWS OF THE STATES OF THE UNITED STATES AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS REQUIRED TO, NOTIFY ANY PURCHASER OF THIS SECURITY FROM IT OF THE RESALE RESTRICTIONS REFERRED TO IN (A) ABOVE. IN ANY CASE, THE HOLDER OF THIS SECURITY WILL NOT, DIRECTLY OR INDIRECTLY, ENGAGE IN ANY HEDGING TRANSACTION WITH REGARD TO THE SECURITY EXCEPT AS PERMITTED UNDER THE SECURITIES ACT.”¹

(2) Upon any sale or transfer of a Transfer Restricted Security (including any Transfer Restricted Security represented by Global Preferred Stock) pursuant to Rule 144 under the Securities Act or another exemption from registration under the Securities Act or an effective registration statement under the Securities Act:

(I) in the case of any Transfer Restricted Security that is a Certificated Preferred Stock, the Transfer Agent shall permit the Holder thereof to exchange such Transfer Restricted Security for Certificated Preferred Stock that

¹ Subject to removal upon registration under the Securities Act of 1933 or otherwise when the security shall no longer be a Transfer Restricted Security.

25

does not bear a restrictive legend and rescind any restriction on the transfer of such Transfer Restricted Security; and

(II) in the case of any Transfer Restricted Security that is represented by a Global Preferred Stock, with the consent of the Company, the Transfer Agent shall permit the Holder thereof to exchange such Transfer Restricted Security for Certificated Preferred Stock that does not bear the legend set forth above and rescind any restriction on the transfer of such Transfer Restricted Security, if the Holder’s request for such exchange was made in reliance on Rule 144 or another exemption from registration under the Securities Act and the Holder certifies to that effect in writing to the Transfer Agent (such certification to be in the form set forth in Exhibit C hereto).

(viii) Cancelation or Adjustment of Global Preferred Stock. At such time as all beneficial interests in Global Preferred Stock have either been exchanged for Certificated Preferred Stock, converted or canceled, such Global Preferred Stock shall be returned to DTC for cancelation or retained and canceled by the Transfer Agent. At any time prior to such cancelation, if any beneficial interest in Global Preferred Stock is exchanged for Certificated Preferred Stock, converted or canceled, the number of shares of Preferred Stock represented by such Global Preferred Stock shall be reduced and an adjustment shall be made on the books and records of the Transfer Agent with respect to such Global Preferred Stock, by the Transfer Agent or DTC, to reflect such reduction.

(ix) Obligations with Respect to Transfers and Exchanges of Preferred Stock.

(1) To permit registrations of transfers and exchanges, the Company shall execute and the Transfer Agent shall authenticate Certificated Preferred Stock and Global Preferred Stock as required pursuant to the provisions of this paragraph 11(c).

(2) All Certificated Preferred Stock and Global Preferred Stock issued upon any registration of transfer or exchange of Certificated Preferred Stock or Global Preferred Stock shall be the valid obligations of the Company, entitled to the same benefits under this Certificate of Designation as the Certificated Preferred Stock or Global Preferred Stock surrendered upon such registration of transfer or exchange.

(3) Prior to due presentment for registration of transfer of any shares of Preferred Stock, the Transfer Agent and the Company may deem and treat the Person in whose name such shares of Preferred Stock are registered as the absolute owner of such Preferred Stock and neither the Transfer Agent nor the Company shall be affected by notice to the contrary.

(4) No service charge shall be made to a Holder for any registration of transfer or exchange upon surrender of any Preferred Stock certificate or Common Stock certificate at the office of the Transfer Agent maintained for that purpose. However, the Company may require payment of a sum sufficient to cover any tax or other

26

governmental charge that may be imposed in connection with any registration of transfer or exchange of Preferred Stock certificates or Common Stock certificates.

(5) Upon any sale or transfer of shares of Preferred Stock (including any Preferred Stock represented by a Global Preferred Stock Certificate) or of Certificated Common Stock pursuant to an effective registration statement under the Securities Act or pursuant to Rule 144 or another exemption from registration under the Securities Act (and based upon an Opinion of Counsel reasonably satisfactory to the Company if it so requests):

(A) in the case of any Certificated Preferred Stock or Certificated Common Stock, the Company and the Transfer Agent shall permit the holder thereof to exchange such Preferred Stock or Certificated Common Stock for Certificated Preferred Stock or Certificated Common Stock, as the case may be, that does not bear a restrictive legend and rescind any restriction on the transfer of such Preferred Stock or Common Stock issuable in respect of the conversion of the Preferred Stock; and

(B) in the case of any Global Preferred Stock, such Preferred Stock shall not be required to bear the legend set forth in paragraph (c)(vii) above but shall continue to be subject to the provisions of paragraph (c)(iv) hereof; provided, however, that with respect to any request for an exchange of Preferred Stock that is represented by Global Preferred Stock for Certificated Preferred Stock that does not bear the legend set forth in paragraph (c)(vii) above in connection with a sale or transfer thereof pursuant to Rule 144 or another exemption from registration under the Securities Act (and based upon an Opinion of Counsel if the Company so requests), the Holder thereof shall certify in writing to the Transfer Agent that such request is being made pursuant to such exemption (such certification to be substantially in the form of Exhibit C hereto).

(x) No Obligation of the Transfer Agent.

(1) The Transfer Agent shall have no responsibility or obligation to any beneficial owner of Global Preferred Stock, a member of, or a participant in DTC or any other Person with respect to the accuracy of the records of DTC or its nominee or of any participant or member thereof, with respect to any ownership interest in the Preferred Stock or with respect to the delivery to any participant, member, beneficial owner or other Person (other than DTC) of any notice or the payment of any amount, under or with respect to such Global Preferred Stock. All notices and communications to be given to the Holders and all payments to be made to Holders under the Preferred Stock shall be given or made only to the Holders (which shall be DTC or its nominee in the case of the Global Preferred Stock). The rights of beneficial owners in any Global Preferred Stock shall be exercised only through DTC subject to the applicable rules and procedures of DTC. The Transfer Agent may rely and shall be fully protected in relying upon information furnished by DTC with respect to its members, participants and any beneficial owners.

27

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

(d) Replacement Certificates. If a mutilated Preferred Stock certificate is surrendered to the Transfer Agent or if the Holder of a Preferred Stock certificate claims that the Preferred Stock certificate has been lost, destroyed or wrongfully taken, the Company shall issue and the Transfer Agent shall countersign a replacement Preferred Stock certificate if the reasonable requirements of the Transfer Agent and of Section 8-405 of the Uniform Commercial Code as in effect in the State of Oklahoma are met. If required by the Transfer Agent or the Company, such Holder shall furnish an indemnity bond sufficient in the judgment of the Company and the Transfer Agent to protect the Company and the Transfer Agent from any loss which either of them may suffer if a Preferred Stock certificate is replaced. The Company and the Transfer Agent may charge the Holder for their expenses in replacing a Preferred Stock certificate.

(e) Temporary Certificates. Until definitive Preferred Stock certificates are ready for delivery, the Company may prepare and the Transfer Agent shall countersign temporary Preferred Stock certificates. Temporary Preferred Stock certificates shall be substantially in the form of definitive Preferred Stock certificates but may have variations that the Company considers appropriate for temporary Preferred Stock certificates. Without unreasonable delay, the Company shall prepare and the Transfer Agent shall countersign definitive Preferred Stock certificates and deliver them in exchange for temporary Preferred Stock certificates.

(f) Cancelation. (i) In the event the Company shall purchase or otherwise acquire Certificated Preferred Stock, the same shall thereupon be delivered to the Transfer Agent for cancelation.

(ii) At such time as all beneficial interests in Global Preferred Stock have either been exchanged for Certificated Preferred Stock, converted, repurchased or canceled, such Global Preferred Stock shall thereupon be delivered to the Transfer Agent for cancelation.

(iii) The Transfer Agent and no one else shall cancel and destroy all Preferred Stock certificates surrendered for transfer, exchange, replacement or cancelation and deliver a certificate of such destruction to the Company unless the Company directs the Transfer Agent to deliver canceled Preferred Stock certificates to the Company. The Company may not issue new Preferred Stock certificates to replace Preferred Stock certificates to the extent they evidence Preferred Stock which the Company has purchased or otherwise acquired.

28

12. Additional Rights of Holders. In addition to the rights provided to Holders under this Certificate of Designation, Holders shall have the rights set forth in the Registration Rights Agreement.

13. Other Provisions.

(a) With respect to any notice to a holder of shares of Preferred Stock required to be provided hereunder, neither failure to mail such notice, nor any defect therein or in the mailing thereof, to any particular holder shall affect the sufficiency of the notice or the validity of the proceedings referred to in such notice with respect to the other holders or affect the legality or validity of any distribution, rights, warrant, reclassification, consolidation, merger, conveyance, transfer, dissolution, liquidation or winding-up, or the vote upon any such action. Any notice which was mailed in the manner herein provided shall be conclusively presumed to have been duly given whether or not the holder receives the notice.

(b) Shares of Preferred Stock issued and reacquired will be retired and canceled promptly after reacquisition thereof and, upon compliance with the applicable requirements of Oklahoma law, have the status of authorized but unissued shares of preferred stock of the Company undesignated as to series and may with any and all other authorized but unissued shares of preferred stock of the Company be designated or redesignated and issued or reissued, as the case may be, as part of any series of preferred stock of the Corporation, except that any issuance or reissuance of shares of Preferred Stock must be in compliance with this Certificate of Designation.

(c) The shares of Preferred Stock shall be issuable only in whole shares.

(d) All notice periods referred to herein shall commence on the date of the mailing of the applicable notice.

IN WITNESS WHEREOF, the Company has caused this certificate to be signed and attested this 29th day of March, 2004.

“Adjusted Consolidated EBITDA Coverage Ratio” means, for any Reference Period, the ratio on a pro forma basis of (a) Adjusted Consolidated EBITDA for the Reference Period to (b) Adjusted Consolidated Interest Expense

for such Reference Period; provided, that, in calculating Adjusted Consolidated EBITDA and Adjusted Consolidated Interest Expense (i) acquisitions which occurred during the Reference Period or subsequent to the Reference Period and on or prior to the date of the transaction giving rise to the need to calculate the Adjusted Consolidated EBITDA Coverage Ratio (the “Transaction Date”) will be given pro forma effect as if they had occurred on the first day of the Reference Period, including any Adjusted Consolidated EBITDA and any pro forma expense and cost reductions that have occurred or are reasonably expected to occur, in the reasonable judgment of the chief financial or accounting officer of the Company regardless of whether those cost savings or operating improvements could then be reflected in pro forma financial statements in accordance with Regulation S-X promulgated under the Securities Act or any other regulation or policy of the SEC related thereto, (ii) the incurrence of any Indebtedness (including the issuance of the Securities) or issuance of any Disqualified Stock during the Reference Period or subsequent to the Reference Period and on or prior to the Transaction Date shall be assumed to have occurred on the first day of such Reference Period, (iii) any Indebtedness that had been outstanding during the Reference Period that has been repaid on or prior to the Transaction Date shall be assumed to have been repaid as of the first day of such Reference Period, (iv) the Adjusted Consolidated Interest Expense attributable to interest on any Indebtedness or dividends on any Disqualified Stock bearing a floating interest (or dividend) rate shall be computed on a pro forma basis as if the rate in effect on the Transaction Date were the average rate in effect during the entire Reference Period and (v) in determining the amount of Indebtedness pursuant to Section 4.09, the incurrence of Indebtedness or issuance of Disqualified Stock giving rise to the need to calculate the Adjusted Consolidated EBITDA Coverage Ratio and, to the extent the net proceeds from the incurrence or issuance thereof are used to retire Indebtedness, the application of the proceeds therefrom shall be assumed to have occurred on the first day of the Reference Period.

THE SECURITIES

SECTION 2.01. Form and Dating. Provisions relating to the Initial Securities, the Private Exchange Securities and the Exchange Securities are set forth in the Rule 144A/Regulation S Appendix attached hereto (the “Appendix”) which is hereby incorporated in and expressly made part of this Indenture. The Initial Securities and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit 1 to the Appendix which is hereby incorporated in and expressly made a part of this Indenture. The Exchange Securities, the Private Exchange Securities and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit A, which is hereby incorporated in and expressly made a part of this Indenture. The Securities may have notations, legends or endorsements required by law, stock exchange rule, agreements to which the Company is subject, if any, or usage (provided that any such notation, legend or endorsement is in a form acceptable to the Company and to the Trustee). Each Security shall be dated the date of its authentication. The terms of the Securities set forth in the Appendix and Exhibit A are part of the terms of this Indenture.

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

21

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

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

On the Issue Date, the Trustee shall authenticate and deliver $600 million of Initial Securities and, at any time and from time to time thereafter, the Trustee shall authenticate and deliver Securities for original issue in an aggregate principal amount specified in such order, in each case upon a written order of the Company signed by two Officers or by an Officer and either an Assistant Treasurer or an Assistant Secretary of the Company. Such order shall specify the amount of the Securities to be authenticated and the date on which the original issue of Securities is to be authenticated and, in the case of an issuance of Additional Securities pursuant to Section 2.13 after the Issue Date, shall certify that such issuance is in compliance with Section 4.09.

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

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

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

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

SECTION 2.04. Paying Agent To Hold Money in Trust. Prior to 11:00 a.m., New York time, each due date of the principal and interest on any Security, the Company shall deposit with the Paying Agent a sum sufficient to pay such principal and interest when so becoming due. The Company shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying

22

Agent shall hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of principal of or interest on the Securities and shall notify the Trustee of any default by the Company in making any such payment. If the Company or a Subsidiary acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as a separate trust fund. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed by the Paying Agent. Upon complying with this Section, the Paying Agent shall have no further liability for the money delivered to the Trustee.

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

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

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

Every replacement Security is an additional obligation of the Company.

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

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

If the Paying Agent segregates and holds in trust, in accordance with this Indenture, on a redemption date or maturity date money sufficient

23

to pay all principal and interest payable on that date with respect to the Securities (or portions thereof) to be redeemed or maturing, as the case may be, then on and after that date such Securities (or portions thereof) cease to be outstanding and interest on them ceases to accrue.

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

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

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

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

SECTION 2.13. Issuance of Additional Securities. The Company shall be entitled, subject to its compliance with Section 4.09(a), to issue Additional Securities under this Indenture which shall have identical terms as the Initial Securities issued on the Issue Date, other than with respect to the date of issuance and issue price. The Initial Securities issued on the Issue Date, any Additional Securities and all Exchange Securities or Private Exchange Securities issued in exchange therefor shall be treated as a single class for all purposes under this Indenture.

24

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

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

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

(3) whether such Additional Securities shall be Transfer Restricted Securities and issued in the form of Initial Securities as set forth in the Appendix to this Indenture or shall be issued in the form of Exchange Securities as set forth in Exhibit A.

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

ARTICLE THREE

REDEMPTION

SECTION 3.01. Notice to Trustee. If the Company elects to redeem Securities pursuant to the optional redemption provisions of Paragraphs 5, 6 or 7 of the Securities, it shall furnish to the Trustee and the Registrar, at least 45 days but not more than 60 days before the redemption date (unless the Trustee consents to a shorter period in writing), an Officers’ Certificate setting forth the redemption date, the principal amount of Securities to be redeemed and the redemption price, including the detail of the calculation of the Make-Whole Price, if applicable.

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

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

25

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

(1) the redemption date;

(2) the redemption price;

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

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

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

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

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

(8) the paragraph of the Securities pursuant to which the Securities called for redemption are being redeemed; and

(9) the CUSIP number of the Securities.

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

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

26

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

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

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

SECTION 3.07. Optional Redemption. Except as set forth in Sections 3.08 and 3.09 hereof, the Company shall not have the option to redeem the Securities prior to July 15, 2010.

27

Any redemption pursuant to this Section 3.08 shall be made, to the extent applicable, pursuant to the provisions of Sections 3.01 through 3.06 hereof.

SECTION 4.04. Maintenance of Office or Agency. The Company will maintain in the Borough of Manhattan, The City of New York, an office or agency where Securities may be surrendered for registration of transfer or exchange or for presentation for payment and where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any

29

time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the address of the Trustee set forth in Section 11.02.

SECTION 4.05. Corporate Existence.

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

(a) The Company shall cause all properties used or held for use in the conduct of its business or the business of any Subsidiary to be maintained and kept in good condition, repair and working order (ordinary wear and tear excepted) and supplied with all necessary equipment and shall cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as in the judgment of the Company may be necessary so that the business carried on in connection therewith may be properly and advantageously conducted at all times; provided, however, that nothing in this Section shall prevent the Company from discontinuing the operation or maintenance of any such property, or disposing of it, if such discontinuance or disposal is, in the judgment of the Company, desirable in the conduct of its business and not disadvantageous in any material respect to the Holders.

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

SECTION 4.09. Limitation on Incurrence of Additional Indebtedness.

(a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, issue, incur, assume, guarantee, become liable, contingently or otherwise, with respect to or otherwise become responsible for the payment of (collectively, “incur”) any Indebtedness; provided, however, that if no Default or Event of Default shall have occurred and be continuing at the time or as a consequence of the incurrence of such Indebtedness, the Company or its Restricted Subsidiaries may incur Indebtedness if, on a pro forma basis, after giving effect to such incurrence and the application of the proceeds therefrom, either of the following tests shall have been satisfied: (i) the Adjusted Consolidated EBITDA Coverage Ratio would have been at least 2.0 to 1.0; or (ii) Adjusted Consolidated Net Tangible Assets would have been greater than 200% of Indebtedness of the Company and its Restricted Subsidiaries.

(b) Notwithstanding the foregoing, if no Default or Event of Default shall have occurred and be continuing at the time or as a consequence of the incurrence of such Indebtedness, the Company and its Restricted Subsidiaries may incur Permitted Indebtedness. For purposes of determining compliance with this Section 4.09:

(i) in the event that an item of proposed Indebtedness meets the criteria of more than one of the categories of Permitted Indebtedness as of the date of incurrence thereof or is entitled to be incurred pursuant to Section 4.09(a) as of the date of incurrence thereof, the Company shall, in its sole discretion, classify (or later classify in whole or in part, in its sole discretion) such item of Indebtedness in any manner that complies with this Section 4.09, and

(ii) for purposes of determining compliance with any dollar-denominated restriction on the incurrence of Indebtedness denominated in a foreign currency, the dollar-equivalent principal amount of such Indebtedness incurred pursuant thereto shall be calculated based on the relevant currency.

31

Accrual of interest or dividends, the accretion of accreted value or liquidation preference and the payment of interest or dividends in the form of additional Indebtedness will not be deemed to be an incurrence of Indebtedness for purposes of this Section 4.09.

(c) Any Indebtedness of a Person existing at the time such Person becomes a Restricted Subsidiary (whether by merger, consolidation, acquisition or otherwise) shall be deemed to be incurred by such Restricted Subsidiary at the time it becomes a Restricted Subsidiary.

SECTION 4.10. Limitation on Restricted Payments. (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, make any Restricted Payment, unless:

(i) no Default or Event of Default shall have occurred and be continuing at the time of or immediately after giving effect to such Restricted Payment;

(ii) at the time of and immediately after giving effect to such Restricted Payment, the Company would be able to incur at least $1.00 of additional Indebtedness (other than Permitted Indebtedness) pursuant to Section 4.09(a); and

(iii) immediately after giving effect to such Restricted Payment, the aggregate of all Restricted Payments declared or made after the Reference Date does not exceed the sum of (A) 50% of the Consolidated Net Income of the Company and its Restricted Subsidiaries (or in the event such Consolidated Net Income shall be a deficit, minus 100% of such deficit) during the period (treated as one accounting period) subsequent to the Reference Date and ending on the last day of the fiscal quarter immediately preceding the date of such Restricted Payment; (B) the aggregate Net Cash Proceeds, and the fair market value of property other than cash (as determined in good faith by the Company’s Board of Directors and evidenced by a resolution of such Board), received by the Company during such period from any Person other than a Subsidiary of the Company as a result of the issuance or sale of Capital Stock of the Company (other than any Disqualified Stock and other than Preferred Shares issued in the Preferred Stock Offering), other than in connection with the conversion of Indebtedness or Disqualified Stock; (C) the aggregate Net Cash Proceeds, and the fair market value of property other than cash (as determined in good faith by the Company’s Board of Directors and evidenced by a resolution of such Board), received by the Company during such period from any Person other than a Subsidiary of the Company as a result of the issuance or sale of any Indebtedness or Disqualified Stock to the extent that at the time the determination is made such Indebtedness or Disqualified Stock, as the case may be, has been converted into or exchanged for Capital Stock of the Company (other than Disqualified Stock); and (D)(i) in case any Unrestricted Subsidiary has been redesignated a Restricted Subsidiary, an amount equal to the lesser of (x) the book value (determined in accordance with GAAP) at the date of such redesignation of the aggregate Investments made by the Company and its Restricted Subsidiaries in such Unrestricted Subsidiary and (y) the fair market value of such Investments in such Unrestricted Subsidiary

32

at the time of such redesignation, as determined in good faith by the Company’s Board of Directors, including a majority of the Company’s Disinterested Directors, whose determination shall be conclusive and evidenced by a resolution of such Board; or (ii) in case any Restricted Subsidiary has been redesignated an Unrestricted Subsidiary, minus the greater of (x) the book value (determined in accordance with GAAP) at the date of redesignation of the aggregate Investments made by the Company and its Restricted Subsidiaries in such Restricted Subsidiary and (y) the fair market value of such Investments in such Restricted Subsidiary at the time of such redesignation, as determined in good faith by the Company’s Board of Directors, including a majority of the Company’s Disinterested Directors, whose determination shall be conclusive and evidenced by a resolution of such Board.

(b) Notwithstanding the foregoing, the above limitations will not prevent (i) the payment of any dividend within 60 days after the date of declaration thereof, if at such date of declaration such payment complied with the provisions hereof; (ii) the making of any Restricted Payment in exchange for, or out of the net proceeds of the substantially concurrent sale (other than to a Restricted Subsidiary of the Company) of, Capital Stock (other than Disqualified Stock) of the Company; (iii) any dividend or other distribution payable from a Restricted Subsidiary to the Company or any other Restricted Subsidiary; (iv) regularly quarterly dividends on the 6.00% Cumulative Convertible Preferred Stock, the 5.00% Cumulative Convertible Preferred Stock or the 4.125% Cumulative Convertible Preferred Stock of the Company outstanding on the Issue Date, provided that no Default or Event of Default shall have occurred and be continuing at the time of or immediately after giving effect to any such Restricted Payment; (v) repurchases, redemptions or other acquisitions or retirements for value of any Capital Stock from employees or directors of the Company or any Restricted Subsidiary in an aggregate amount not to exceed $3,000,000 in any calendar year; and (vi) other Restricted Payments not in excess of $35,000,000 in the aggregate since the Issue Date, provided that no Default or Event of Default shall have occurred and be continuing at the time of or immediately after giving effect to any such Restricted Payment. Any Restricted Payment described in the preceding clause (iii) shall be excludable in the calculation of the amount of Restricted Payments, and any Restricted payment described in any other clause shall be included in the calculation.

SECTION 4.11. Limitation on Sale of Assets. (a) The Company will not, and will not permit any Restricted Subsidiary to, make any Asset Sale unless:

(i) the Company (or its Restricted Subsidiaries, as the case may be) receives consideration at the time of such sale or other disposition at least equal to the fair market value thereof (as determined in good faith by the Company’s Board of Directors and evidenced by a resolution of such Board, including a majority of the Company’s Disinterested Directors, in the case of any Asset Sales or series of related Asset Sales having a fair market value of $50,000,000 or greater);

(ii) (A) the consideration consists of cash, cash equivalents, Permitted Financial Investments or property, equipment, leasehold interests or other assets used in the Oil and Gas Business (“Permitted Consideration”) or (B) the portion of the consideration that does not constitute Permitted Consideration, together with all other consideration received for Asset Sales since the Issue Date that does not constitute Permitted Consideration, has a fair market value of no more than 10% of ACNTA; and

33

(iii) the Net Available Proceeds received by the Company (or its Restricted Subsidiaries, as the case may be) from such Asset Sale are applied in accordance with paragraphs (b) or (c) hereof.

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

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

(d) The Company shall commence a Net Proceeds Offer by preparing and mailing a notice to the Trustee, the Paying Agent and each Holder as of such record date as the Company shall establish (upon written notice to the Trustee). Notice of a Net Proceeds Offer to purchase the Securities will be made on behalf of the Company not less than 25 Business Days nor more than 60 Business Days before the payment date of the Net Proceeds Offer (the “Net Proceeds Payment Date”), and shall set forth the Net Proceeds Offer Amount and the Net Proceeds Payment Date and refer to and summarize the material points contained in Sections 4.11(d) and (e) hereof. Securities tendered to the Company pursuant to a Net Proceeds Offer will cease to accrue interest after the Net Proceeds Payment Date. For purposes of this covenant, the term “Net Proceeds Offer Amount” means the principal of outstanding Securities in an aggregate principal amount equal to any remaining Net Available Proceeds (rounded to the next lowest $1,000). If the Net Proceeds Payment Date is on or after an interest payment record date and on or before the related interest payment date, any accrued interest payable on such interest payment date will be paid to the Person in whose name a Security is registered at the close of business on such record date, and no additional interest will be payable to Holders who tender Securities pursuant to the Net Proceeds Offer.

(e) On the Net Proceeds Payment Date, the Company will (i) accept for payment Securities and any other Senior Indebtedness in respect of which such an offer to purchase is required to be made concurrently with the Net Proceeds Offer or portions thereof pursuant to the

34

Net Proceeds Offer in an aggregate principal amount equal to the Net Proceeds Offer Amount or such lesser amount as has been tendered, (ii) deposit with the Paying Agent (or if the Company or a Subsidiary is the Paying Agent, shall segregate and hold in trust) money sufficient to pay the purchase price of all Securities and such other Senior Indebtedness or portions thereof so tendered in an aggregate principal amount equal to the Net Proceeds Offer Amount or such lesser amount, including any accrued and unpaid interest thereon, and (iii) deliver or cause to be delivered to the Trustee, Securities so accepted together with an Officers’ Certificate stating the Securities or portions thereof tendered to the Company. If the aggregate principal amount of Securities and such other Senior Indebtedness tendered exceeds the Net Proceeds Offer Amount, the Trustee will select the Securities and other Senior Indebtedness to be purchased (in integral multiples of $1,000) on a pro rata basis based on the principal amount of Securities and other Senior Indebtedness so tendered and notify the Company, the Registrar and the Paying Agent. The Paying Agent, upon instruction of the Company, will promptly mail or deliver to Holders of Securities so accepted payment in an amount equal to the purchase price (representing those funds received pursuant to clause (ii) of this Section 4.11(e)), and the Company will execute and the Trustee will promptly authenticate and mail or make available for delivery to Holders a new Security equal in principal amount to any unpurchased portion of the Security surrendered. Any Securities not so accepted will be promptly mailed or delivered to the Holder thereof by the Company, or, if the Company so directs the Trustee, by the Trustee on behalf of the Company at the Company’s expense. The Company will publicly announce the results of the Net Proceeds Offer on or as soon as practicable after the Net Proceeds Payment Date. For purposes of this Section 4.11, the Trustee will act as the Paying Agent.

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

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

SECTION 4.12. Limitation on Liens Securing Indebtedness. The Company will not, and will not permit any Restricted Subsidiary to, create, incur, assume or suffer to exist any Liens (other than Permitted Liens) upon any of their respective properties securing any Indebtedness of the Company or any Restricted Subsidiary, unless the Securities or a Guarantee are equally and ratably secured; provided, that if such Indebtedness is expressly subordinated to the Securities or a Guarantee, the Lien securing such Indebtedness will be subordinated and junior to the Lien securing the Securities or such Guarantee.

SECTION 4.13. Limitation on Sale/Leaseback Transactions. The Company will not, and will not permit any of its Restricted Subsidiaries to, enter into any Sale/Leaseback Transaction with any Person (other than the Company or any other Restricted Subsidiary) unless (i) the Company or such Restricted Subsidiary, as the case may be, would be able to incur Indebtedness in a principal amount equal to the Attributable Indebtedness with respect to such Sale/Leaseback Transaction in accordance with Section 4.09 or (ii) the Company or such Restricted Subsidiary receives proceeds from such

35

Sale/Leaseback Transaction at least equal to the fair market value thereof (as determined in good faith by the Company’s Board of Directors, whose determination in good faith, evidenced by a resolution of such Board shall be conclusive) and such proceeds are applied in the same manner and to the same extent as Net Available Proceeds and Excess Proceeds from an Asset Sale.

SECTION 4.14. Limitation on Payment Restrictions Affecting Subsidiaries. The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to exist or become effective any consensual encumbrance or consensual restriction on the ability of any Restricted Subsidiary of the Company to (i) pay dividends or make any other distributions on its Capital Stock to the Company or a Restricted Subsidiary, (ii) pay any Indebtedness owed to the Company or a Restricted Subsidiary of the Company; (iii) make loans or advances to the Company or a Restricted Subsidiary of the Company; or (iv) transfer any of its properties or assets to the Company or a Restricted Subsidiary of the Company (each, a “Payment Restriction”), except for (a) encumbrances or restrictions under Credit Facilities; provided, that any Payment Restrictions thereunder (other than, with respect to (iv) above, customary restrictions in security agreements or other loan documents thereunder securing or governing Indebtedness of a Restricted Subsidiary) may be imposed only upon the acceleration of the maturity of the Indebtedness thereunder; (b) consensual encumbrances or consensual restrictions binding upon any Person at the time such Person becomes a Restricted Subsidiary of the Company (unless the agreement creating such consensual encumbrances or consensual restrictions was entered into in connection with, or in contemplation of, such entity becoming a Restricted Subsidiary); (c) consensual encumbrances or consensual restrictions under any agreement that refinances or replaces any agreement described in clauses (a) and (b) above, provided that the terms and conditions of any such restrictions are in the aggregate no less favorable to the holders of the Securities than those under the agreement so refinanced or replaced; and (d) customary non-assignment provisions in leases, purchase money financings and any encumbrance or restriction due to applicable law.

SECTION 4.15. Limitation on Transactions with Affiliates. The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, enter into any transaction or series of transactions (including, without limitation, the sale, purchase or lease of any assets or properties or the rendering of any services) with any Affiliate or beneficial owner (as defined in Rules 13d-3 and 13d-5 under the Exchange Act) of 10% or more of the Company’s common stock (other than with a Restricted Subsidiary of the Company) (an “Affiliate Transaction”), on terms that are less favorable to the Company or such Restricted Subsidiary, as the case may be, than would be available in a comparable transaction with an unrelated Person. In addition, the Company will not, and will not permit any Restricted Subsidiary of the Company to, enter into an Affiliate Transaction, or any series of related Affiliate Transactions having a value of (a) more than $15,000,000 unless a majority of the Board of Directors of the Company (including a majority of the Company’s Disinterested Directors) determines in good faith, as evidenced by a resolution of such Board, that such Affiliate Transaction or series of related Affiliate Transactions is fair to the Company; or (b) more than $35,000,000, unless the Company receives a written opinion from a nationally recognized investment banking firm with total assets in excess of $1,000,000,000 that such transaction or series of transactions is fair to the Company from a financial point of view.

36

SECTION 4.16. Change of Control. (a) Following the occurrence of any Change of Control Triggering Event, the Company shall offer (a “Change of Control Offer”) to purchase all outstanding Securities at a purchase price equal to 101% of the aggregate outstanding principal amount of the Securities, plus accrued and unpaid interest on the Securities so purchased to the date of purchase. The Change of Control Offer shall be deemed to have commenced upon mailing of the notice described in the next succeeding paragraph and shall terminate 20 Business Days after its commencement, unless a longer offering period is required by law. Promptly after the termination of the Change of Control Offer (the “Change of Control Payment Date”), the Company shall purchase and mail or deliver payment for all Securities tendered in response to the Change of Control Offer. If the Change of Control Payment Date is on or after an interest payment record date and on or before the related interest payment date, any accrued interest payable on such interest payment date will be paid to the Person in whose name a Security is registered at the close of business on such record date, and no additional interest will be payable to Holders who tender Securities pursuant to the Change of Control Offer.

(b) Within 15 days after any Change of Control Triggering Event, the Company (with notice to the Trustee and the Paying Agent), or the Trustee at the Company’s request and expense, will mail or cause to be mailed to all Holders on the date of the Change of Control Triggering Event a notice prepared by the Company (the “Change of Control Notice”) of the occurrence of such Change of Control Triggering Event and of the Holders’ rights arising as a result thereof. The Change of Control Notice will contain all instructions and materials necessary to enable Holders to tender their Securities to the Company. The Change of Control Notice, which shall govern the terms of the Change of Control Offer, shall state: (1) that the Change of Control Offer is being made pursuant to this Section 4.16; (2) the purchase price and the Change of Control Payment Date; (3) that any Security not tendered will continue to accrue interest at the stated rate; (4) that any Security accepted for payment pursuant to the Change of Control Offer shall cease to accrue interest on the Change of Control Payment Date; (5) that Holders electing to have a Security purchased pursuant to any Change of Control Offer will be required to surrender the Security, with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Security completed, to the Company, a depositary, if appointed by the Company, or a Paying Agent at the address specified in the notice prior to termination of the Change of Control Offer; (6) that Holders will be entitled to withdraw their election if the Company, depositary or Paying Agent, as the case may be, receives, not later than the expiration of the Change of Control Offer, or such longer period as may be required by law, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Security the Holder delivered for purchase and a statement that such Holder is withdrawing its election to have the Security purchased; and (7) that Holders whose Securities are purchased only in part will be issued Securities equal in principal amount to the unpurchased portion of the Securities surrendered.

(c) On the Change of Control Payment Date, the Company shall, to the extent permitted by applicable law, (i) accept for payment Securities or portions thereof tendered pursuant to the Change of Control Notice, (ii) if the Company appoints a depositary or Paying Agent, deposit with such depositary or Paying Agent money sufficient to pay the purchase price of all Securities or portions thereof so tendered and (iii) deliver to the Trustee Securities so accepted together with an Officers’ Certificate stating the Securities or portions thereof tendered to the Company. The depositary, the

37

Company or the Paying Agent, as the case may be, shall promptly mail to the Holders of Securities so accepted payment in an amount equal to the purchase price (representing those funds received pursuant to clause (ii) of this Section 4.16(c)), and the Trustee shall promptly authenticate and mail to each such Holder a new Security equal in principal amount to any unpurchased portion of the Security surrendered; provided that each such new Security will be in a principal amount of $1,000 or an integral multiple thereof. The Company will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date. For purposes of this Section 4.16, the Trustee shall act as the Paying Agent.

(d) The Company will comply with Section 14 of the Exchange Act and the provisions of Regulation 14E and any other tender offer rules under the Exchange Act and any other federal and state securities laws, rules and regulations which may then be applicable to any offer by the Company to purchase the Securities at the option of the Holders upon a Change of Control.

SECTION 4.17. Covenant Termination. (a) If at any time (i) the rating assigned to the Securities by either S&P or Moody’s is an Investment Grade Rating and (ii) no Event of Default has occurred and is continuing under the Indenture, then upon notice thereof from the Company to the Trustee, the Company and its Restricted Subsidiaries will no longer be subject Sections 4.09, 4.10, 4.11, 4.14, 4.15 and 4.16 and, without limiting the remainder of Article Five, the financial test set out in clause (3) of Section 5.01 shall not apply.

(b) Following any termination of the covenants under this Section 4.17, the Company may not designate any Subsidiary to be an Unrestricted Subsidiary.

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

The Holders of a majority of the principal amount of the outstanding Securities, by written notice to the Company, the Subsidiary Guarantors and the Trustee, may rescind and annul a declaration of acceleration and its consequences if (1) the Company or any Subsidiary Guarantor has paid or deposited with such Trustee a sum sufficient to pay (A) all overdue installments of interest on all the Securities, (B) the principal of, and premium, if any, on any Securities that have become due otherwise than by such declaration of acceleration and interest thereon at

No such rescission will affect any subsequent Event of Default or impair any right consequent thereon.

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

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

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

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

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

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

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

42

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

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

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

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

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

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

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

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

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

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

Second: to Holders for amounts due and unpaid on the Securities for principal and interest, ratably, without

43

preference or priority of any kind, according to the amounts due and payable on the Securities for principal and interest, respectively; and

Third: to the Company.

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

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

ARTICLE SEVEN

TRUSTEE

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

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

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

(2) In the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, in the case of certificates or opinions specifically required by any provision hereof to be furnished to it, the Trustee shall examine such certificates and opinions to determine whether or not they conform to the requirements of this Indenture.

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

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

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

44

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

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

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

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

(a) The Trustee may conclusively rely on and shall be fully protected in acting or refraining from acting upon any document believed by it to be genuine and to have been signed or presented by the proper person. The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney, to the extent reasonably required by such inquiry or investigation at the expense of the Company and shall incur no liability of any kind by reason of such inquiry or investigation.

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

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

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

45

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

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

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

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

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

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

SECTION 7.04. Trustee’s Disclaimer. The Trustee makes no representation as to the validity or adequacy of this Indenture or the Securities, it shall not be accountable for the Company’s use of the proceeds from the Securities or any prospectus, offering or solicitation documents, and it shall not be responsible for any statement in the Securities other than its certificate of authentication.

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

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

46

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

The Trustee shall not be under any obligation to institute any suit, or take any remedial action under this Indenture, or to enter any appearance or in any way defend any suit in which it may be a defendant, or to take any steps in the execution of the trusts created hereby or thereby or in the enforcement of any rights and powers under this Indenture, until it shall be indemnified to its satisfaction against any and all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provisions of this Indenture, including compensation for services, costs, expenses, outlays, counsel fees and other disbursements, and against all liability (including fees and expenses incurred by the Trustee pursuant to the penultimate paragraph of Section 7.08) not due to its negligence or willful misconduct. The Company and the Subsidiary Guarantors jointly and severally agree to indemnify the Trustee against any loss, liability, claim, damage or expenses incurred by it arising out of or in connection with the acceptance and administration of the trust and its duties hereunder as Trustee, Registrar and/or Paying Agent, including the costs and expenses of enforcing this Indenture against the Company (including with respect to this Section 7.07) and of defending itself against any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder. The Trustee shall notify the Company and the Subsidiary Guarantors of any claim of which a Trust Officer has received written notice for which it may seek indemnity; however, unless the position of the Company is prejudiced by such failure, the failure of the Trustee to promptly notify the Company shall not limit its right to indemnification. The Company shall defend each such claim and the Trustee shall cooperate in the defense. The Trustee may retain separate counsel and the Company shall reimburse the Trustee for the reasonable fees and expenses of such counsel. The Company need not pay for any settlement made without its consent.

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

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

47

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

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

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

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

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

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

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

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

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

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

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

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

48

SECTION 7.11. Preferential Collection of Claims Against Company. The Trustee shall comply with TIA Section 311(a), excluding any creditor relationship listed in TIA Section 311(b). A Trustee who has resigned or been removed shall be subject to TIA Section 311(a) to the extent indicated therein.

ARTICLE EIGHT

DISCHARGE OF INDENTURE

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

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

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

SECTION 8.03. Covenant Defeasance. Upon the Company’s exercise under Section 8.01 of the option applicable to this Section 8.03, the Company shall be released from its obligations under the covenants contained in the second sentence of Section 4.02, Sections 4.03, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14, 4.15 and 4.16 and Article Five with respect to the outstanding Securities on and after the date the conditions set forth below are satisfied (hereinafter, “Covenant Defeasance”), and the Securities shall thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Securities shall not be deemed outstanding for accounting purposes). For this purpose, such Covenant Defeasance means that, with respect to the outstanding

49

Securities, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.01(5), but, except as specified above, the remainder of this Indenture and such Securities shall be unaffected thereby. In addition, upon the Company’s exercise under Section 8.01 of the option applicable to this Section 8.03, Sections 6.01(4) through 6.01(9) shall not constitute Events of Default.

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

(b) In the case of an election under Section 8.02, the Company shall have delivered to the Trustee an Opinion of Counsel confirming that (i) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (ii) since the date hereof, there has been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such opinion shall confirm that, the Holders of the outstanding Securities will not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

(c) In the case of an election under Section 8.03, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of the outstanding Securities will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

50

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

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

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

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

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

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

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

51

SECTION 8.06. Repayment to Company. Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, premium, if any, or interest on any Security which is not subject to the last paragraph of Section 8.05 and has remained unclaimed for two years after such principal, and premium, if any, or interest has become due and payable shall be paid to the Company on its request (unless an abandoned property law designates another Person) or (if then held by the Company) shall be discharged from such trust; and the Holder of such Securities shall thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in the New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining will be repaid to the Company.

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

ARTICLE NINE

After an amendment or waiver under this Section becomes effective, the Company shall mail to the Holders of each Security affected thereby a notice briefly describing the amendment or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such supplemental indenture.

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

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

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

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

53

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

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

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

(5) reduce the repurchase price, including premium, if any, payable upon the repurchase of any Security pursuant to Sections 4.11 or 4.16, or change the time at which any Security may or shall be repurchased thereunder;

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

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

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

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

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

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

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

54

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

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

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

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

ARTICLE TEN

GUARANTEES

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

Failing payment when due of any amount so guaranteed for whatever reason, the Subsidiary Guarantors will be jointly and severally obligated to pay the same immediately. Each Subsidiary Guarantor hereby agrees that its

55

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

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

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

56

under its Guarantees; provided that in the event such sale or disposition constitutes an Asset Sale, the Net Available Proceeds of such sale or other disposition are applied in accordance with the provisions of this Indenture described under Section 4.11.

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

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

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

57

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

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

SECTION 10.07. [Intentionally Omitted.]

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

(iii) In the event that a Restricted Global Security is exchanged for Securities in certificated registered form pursuant to Section 2.4 of this Appendix, prior to the consummation of a Registered Exchange Offer or the effectiveness of a Shelf Registration Statement with respect to such Securities, such Securities may be exchanged only in accordance with such procedures as are substantially consistent with the provisions of this Section 2.3 (including the certification requirements set forth on the reverse of the Initial Securities intended to ensure that such transfers comply with Rule 144A or Regulation S, as the case may be) and such other procedures as may from time to time be adopted by the Company.

(b) Legend.

(i) Except as permitted by the following paragraphs (ii), (iii) and (iv), until the expiration of the applicable holding period with respect to the Securities set forth in Rule 144(k) of the Securities Act, each Security certificate evidencing the Restricted Global Securities (and all Securities issued in exchange therefor or in substitution thereof) shall bear a legend in substantially the following form:

THIS SECURITY (OR ITS PREDECESSOR) WAS ORIGINALLY ISSUED IN A TRANSACTION EXEMPT FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933 (THE “SECURITIES ACT”), AND THIS SECURITY MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM. EACH PURCHASER OF THIS SECURITY IS HEREBY NOTIFIED THAT THE SELLER OF THIS SECURITY MAY BE RELYING ON THE EXEMPTION FROM THE PROVISIONS OF SECTION 5 OF THE SECURITIES ACT PROVIDED BY RULE 144A THEREUNDER.

THE HOLDER OF THIS SECURITY AGREES FOR THE BENEFIT OF THE COMPANY THAT (A) THIS NOTE MAY BE OFFERED, RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (I) THE COMPANY, (II) IN THE UNITED STATES TO A PERSON WHOM THE SELLER REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) IN A TRANSACTION MEETING THE REQUIREMENTS OF RULE 144A, (III) OUTSIDE THE UNITED STATES IN AN OFFSHORE TRANSACTION IN ACCORDANCE WITH RULE 904 UNDER THE SECURITIES ACT, (IV) PURSUANT TO EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT PROVIDED BY RULE 144 THEREUNDER (IF AVAILABLE) OR (V) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, IN EACH OF CASES (I) THROUGH (V) IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES, AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS REQUIRED TO, NOTIFY ANY PURCHASER OF THIS SECURITY FROM IT OF THE RESALE RESTRICTIONS REFERRED TO IN (A) ABOVE.

A-4

(ii) Upon any sale or transfer of a Transfer Restricted Security (including any Transfer Restricted Security represented by a Restricted Global Security) pursuant to Rule 144 under the Securities Act, the Registrar shall permit the transferee thereof to exchange such Transfer Restricted Security for a certificated Security that does not bear the legend set forth above and rescind any restriction on the transfer of such Transfer Restricted Security, if the transferor thereof certifies in writing to the Registrar that such sale or transfer was made in reliance on Rule 144 (such certification to be in the form set forth on the reverse of the Security).

(iii) After a transfer of any Initial Securities or Private Exchange Securities pursuant to and during the period of the effectiveness of a Shelf Registration Statement with respect to such Initial Securities or Private Exchange Securities, as the case may be, all requirements pertaining to legends on such Initial Security or such Private Exchange Security will cease to apply, the requirements requiring any such Initial Security or such Private Exchange Security issued to certain Holders be issued in global form will cease to apply, and a certificated Initial Security or Private Exchange Security or an Initial Security or Private Exchange Security in global form, in each case without restrictive transfer legends, will be available to the transferee of the Holder of such Initial Securities or Private Exchange Securities upon exchange of such transferring Holder’s certificated Initial Security or Private Exchange Security or directions to transfer such Holder’s interest in the Global Security, as applicable.

(iv) Upon the consummation of a Registered Exchange Offer with respect to the Initial Securities, all requirements pertaining to such Initial Securities that Initial Securities issued to certain Holders be issued in global form will still apply with respect to Holders of such Initial Securities that do not exchange their Initial Securities, and Exchange Securities in certificated or global form will be available to Holders that exchange such Initial Securities in such Registered Exchange Offer.

(v) Upon the consummation of a Private Exchange with respect to the Initial Securities, all requirements pertaining to such Initial Securities that Initial Securities issued to certain Holders be issued in global form will still apply with respect to Holders of such Initial Securities that do not exchange their Initial Securities, and Private Exchange Securities in global form with the global securities legend and the Restricted Securities Legend set forth in Exhibit 1 hereto will be available to Holders that exchange such Initial Securities in such Private Exchange.

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

A-5

then the Securities Custodian for such Global Security) with respect to such Global Security, by the Trustee or the Securities Custodian, to reflect such reduction.

(ii) 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, assessments, or similar governmental charge payable in connection therewith (other than any such transfer taxes, assessments or similar governmental charge payable upon exchange or transfer pursuant to Sections 3.06 and 4.16 of the Indenture).

(iii) The Registrar or co-registrar shall not be required to register the transfer of or exchange of any Security for a period beginning 15 Business Days before the mailing of a notice of an offer to repurchase or redeem Securities or 15 Business Days before an interest payment date.

(e) No Obligation of the Trustee.

(i) The Trustee shall have no responsibility or obligation to any beneficial owner of a Global Security, Agent Member or other Person with respect to the accuracy of the records of the Depository or its nominee or of any Agent Member, with respect to any ownership interest in the Securities or with respect to the delivery to any Agent Member, beneficial owner or other Person (other than the Depository) of any notice (including any notice of redemption) or the payment of any amount, under or with respect to such Securities. All notices and communications to be given to the Holders and all payments to be made to Holders under the Securities shall be given or made only to or upon the order of the registered Holders (which shall be the Depository or its nominee in the case of a Global Security). The rights of beneficial owners in any Global Security shall be exercised only through the Depository subject to the applicable rules and procedures of the Depository. The Trustee may rely and shall be fully protected in relying upon information furnished by the Depository with respect to its Agent Member and any beneficial owners.

A-6

[REVERSE SIDE OF INITIAL SECURITY]

6.25% Senior Note due 2018

1. Interest

Chesapeake Energy Corporation, an Oklahoma corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred to, being herein called the “Company”), promises to pay interest on the principal amount of this Security at the rate per annum shown above; provided, however, that if a Registration Default (as defined in the Registration Rights Agreement) occurs, additional interest will accrue on this Security at a rate of 0.25% per annum (increasing by an additional 0.25% per annum after each consecutive 90-day period that occurs after the date on which such Registration Default occurs up to a maximum additional interest rate of 1.00%) from and including the date on which any such Registration Default shall occur to but excluding the date on which all Registration Defaults have been cured. The Company will pay interest semiannually on January 15 and July 15 of each year, commencing January 15, 2006. Interest on the Securities will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from June 20, 2005. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

2. Method of Payment

The Company will pay interest on the Securities (except defaulted interest) to the Persons who are registered holders of Securities at the close of business on the January 1 or July 1 next preceding the interest payment date even if Securities are canceled after the record date and on or before the interest payment date. Holders must surrender Securities to a Paying Agent to collect principal payments. The Company will pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. Payments in respect of the Securities represented by a Global Security (including principal, premium and interest) will be made by wire transfer of immediately available funds to the accounts specified by The Depository Trust Company. The Company will make all payments in respect of a certificated Security (including principal, premium and interest) by mailing a check to the registered address of each Holder thereof; provided, however, that payments on a certificated Security will be made by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than 30 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion).

3. Paying Agent and Registrar

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

4. Indenture

The Company issued the Securities under an Indenture dated as of June 20, 2005 (“Indenture”), among the Company, the Subsidiary Guarantors and the Trustee. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) as in effect on the date of the Indenture (the “Act”). Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture. The Securities are subject to all such terms, and Holders are referred to the Indenture and the Act for a statement of those terms.

The Company shall be entitled, subject to its compliance with Section 4.09(a) of the Indenture, to issue Additional Securities pursuant to Section 2.13 of the Indenture. The Initial Securities issued on the Issue Date, any Additional Securities and all Exchange Securities or Private Exchange Securities issued in exchange therefor will be treated as a single class for all purposes under the Indenture.

The Securities may be redeemed at the option of the Company, in whole or from time to time in part, at any time on or after July 15, 2010, at the redemption prices set forth below (expressed as a percentage of the principal amount of the Securities to be redeemed), together with accrued and unpaid interest on the Securities so redeemed to the redemption date, if redeemed during the 12-month period commencing on July 15 of the years indicated below:

Any redemption pursuant to this paragraph 6 shall be made, to the extent applicable, pursuant to the provisions of Sections 3.01 through 3.06 of the Indenture.

B-4

Any redemption pursuant to this paragraph 7 shall be made, to the extent applicable, pursuant to the provisions of Sections 3.01 through 3.06 of the Indenture.

8. Notice of Redemption

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

9. Change of Control Offer

In the event of a Change of Control Triggering Event, the Company shall be required to make an offer to purchase all or any portion of each Holder’s Securities, at 101% of the principal amount thereof, plus accrued and unpaid interest to the date of purchase.

10. Net Proceeds Offer

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

11. Restrictive Covenants

The Indenture imposes certain limitations on, among other things, the ability of the Company to merge or consolidate with any other Person or sell, lease or otherwise transfer all or substantially all of its properties or assets, the ability of the Company or the Restricted Subsidiaries to dispose of assets, to pay dividends and make certain other distributions and payments, to make certain investments or redeem, retire, repurchase or acquire for value shares of Capital Stock, to incur additional Indebtedness or incur encumbrances against certain property and to enter into certain transactions with Affiliates, all subject to certain limitations described in the Indenture and some of which will cease to have effect, upon notice from the Company to the Trustee, if the Company obtains an Investment Grade Rating and no Event of Default has occurred and is continuing.

B-5

12. Ranking and Guarantees

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

13. Denominations; Transfer; Exchange

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

14. Persons Deemed Owners

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

15. Unclaimed Money

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

16. Discharge and Defeasance

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

17. Amendment, Supplement, Waiver

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

B-6

18. Successor Corporation

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

19. Defaults and Remedies

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

20. Trustee Dealings with Company and Subsidiary Guarantors

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

21. No Recourse Against Others

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

[FORM OF REVERSE SIDE OF EXCHANGE SECURITY

OR PRIVATE EXCHANGE SECURITY]

6.25% Senior Note due 2018

1. Interest

Chesapeake Energy Corporation, an Oklahoma corporation (such corporation, and its successors and assigns under the Indenture hereinafter referred to, being herein called the “Company”), promises to pay interest on the principal amount of this Security at the rate per annum shown above; provided, however, that if a Registration Default (as defined in the Registration Rights Agreement) occurs, additional interest will accrue on this Security at a rate of 0.25% per annum (increasing by an additional 0.25% per annum after each consecutive 90-day period that occurs after the date on which such Registration Default occurs up to a maximum additional interest rate of 1.00%) from and including the date on which any such Registration Default shall occur to but excluding the date on which all Registration Defaults have been cured.** The Company will pay interest semiannually on January 15 and July 15 of each year, commencing January 15, 2006. Interest on the Securities will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from June 20, 2005. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

2. Method of Payment

The Company will pay interest on the Securities (except defaulted interest) to the Persons who are registered holders of Securities at the close of business on the January 1 or July 1 next preceding the interest payment date even if Securities are canceled after the record date and on or before the interest payment date. Holders must surrender Securities to a Paying Agent to collect principal payments. The Company will pay principal and interest in money of the United States that at the time of payment is legal tender for payment of public and private debts. Payments in respect of the Securities represented by a Global Security (including principal, premium and interest) will be made by wire transfer of immediately available funds to the accounts specified by The Depository Trust Company. The Company will make all payments in respect of a certificated Security (including principal, premium and interest) by mailing a check to the registered address of each Holder thereof; provided, however, that payments on a certificated Security will be made by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than 30 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion).

** Insert if at the date of issuance of the Exchange Security or Private Exchange Security (as the case may be) any Registration Default has occurred with respect to the related Initial Securities during the interest period in which such date of issuance occurs.

C-3

3. Paying Agent and Registrar

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

4. Indenture

The Company issued the Securities under an Indenture dated as of June 20, 2005 (“Indenture”), among the Company, the Subsidiary Guarantors and the Trustee. The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. §§ 77aaa-77bbbb) as in effect on the date of the Indenture (the “Act”). Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture. The Securities are subject to all such terms, and Holders are referred to the Indenture and the Act for a statement of those terms.

The Company shall be entitled, subject to its compliance with Section 4.09(a) of the Indenture, to issue Additional Securities pursuant to Section 2.13 of the Indenture. The Initial Securities issued on the Issue Date, any Additional Securities and all Exchange Securities or Private Exchange Securities issued in exchange therefor will be treated as a single class for all purposes under the Indenture.

5. Optional Redemption

The Securities may be redeemed at the option of the Company, in whole or from time to time in part, at any time on or after, at the redemption prices set forth below (expressed as a percentage of the principal amount of the Securities to be redeemed), together with accrued and unpaid interest on the Securities so redeemed to the redemption date, if redeemed during the 12-month period commencing on July 15 of the years indicated below:

Year	Redemption Price
2010	103.125	%
2011	102.083	%
2012	101.042	%
2013 and thereafter	100.000	%

Any redemption pursuant to this paragraph 5 shall be made, to the extent applicable, pursuant to the provisions of Sections 3.01 through 3.06 of the Indenture.

6. Equity Offering Redemption

In the event the Company consummates one or more Equity Offerings on or prior to July 15, 2008, the Company may redeem, in its sole discretion, up to 35% of the aggregate principal amount of the Securities (which includes Additional Securities, if any) with all or a portion of the aggregate net proceeds received by the Company from any such Equity Offering or Equity Offerings at a redemption price of 106.25% of the aggregate principal amount

C-4

of the Securities so redeemed, plus accrued and unpaid interest on the Securities so redeemed to the redemption date; provided, however, that (i) the date of any such redemption occurs within the 120-day period after the Equity Offering in respect of which such redemption is made and (ii) following each such redemption, at least 65% of the aggregate principal amount of the Securities (which includes Additional Securities, if any) remains outstanding. Any redemption pursuant to this paragraph 6 shall be made, to the extent applicable, pursuant to the provisions of Sections 3.01 through 3.06 of the Indenture.

7. Make-Whole Price Redemption

At any time prior to July 15, 2010, the Company may, at its option, redeem all or any portion of the Securities at the “Make-Whole Price” (as defined in the Indenture) plus accrued and unpaid interest on the Securities so redeemed to the date of redemption. Any redemption pursuant to this paragraph 7 shall be made, to the extent applicable, pursuant to the provisions of Sections 3.01 through 3.06 of the Indenture.

8. Notice of Redemption

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

9. Change of Control Offer

In the event of a Change of Control Triggering Event, the Company shall be required to make an offer to purchase all or any portion of each Holder’s Securities, at 101% of the principal amount thereof, plus accrued and unpaid interest to the date of purchase.

10. Net Proceeds Offer

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

11. Restrictive Covenants

The Indenture imposes certain limitations on, among other things, the ability of the Company to merge or consolidate with any other Person or sell, lease or otherwise transfer all or substantially all of its properties or assets, the ability of the Company or the Restricted Subsidiaries to dispose of assets, to pay dividends and make certain other distributions and

C-5

payments, to make certain investments or redeem, retire, repurchase or acquire for value shares of Capital Stock, to incur additional Indebtedness or incur encumbrances against certain property and to enter into certain transactions with Affiliates, all subject to certain limitations described in the Indenture and some of which will cease to have effect if the Company obtains an Investment Grade Rating and no Event of Default has occurred and is continuing.

12. Ranking and Guarantees

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

13. Denominations; Transfer; Exchange

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

14. Persons Deemed Owners

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

15. Unclaimed Money

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

16. Discharge and Defeasance

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

17. Amendment, Supplement, Waiver

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

C-6

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

18. Successor Corporation

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

19. Defaults and Remedies

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

20. Trustee Dealings with Company and Subsidiary Guarantors

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

21. No Recourse Against Others

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

C-7
