NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

A.	Summary of Accounting Policies

Our accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America and reflect all adjustments that, in our opinion, are necessary for a fair presentation of the results for the interim periods presented. All such adjustments are of a normal recurring nature. Due to the seasonal nature of our business, the results of operations for the three and nine months ended September 30, 2005, are not necessarily indicative of the results that may be expected for a twelve-month period. These unaudited consolidated financial statements should be read in conjunction with our audited consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2004.

Our accounting policies are consistent with those disclosed in Note A of the Notes to Consolidated Financial Statements in our Annual Report on Form 10-K for the year ended December 31, 2004.

Critical Accounting Policies

Impairment of Long-Lived Assets - We assess our long-lived assets for impairment based on Statement of Financial Accounting Standards No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets” (Statement 144). A long-lived asset is tested for impairment whenever events or changes in circumstances indicate that its carrying amount may exceed its fair value. Fair values are based on the sum of the undiscounted future cash flows expected to result from the use and eventual disposition of the assets.

Examples of long-lived asset impairment indicators include:

•

a significant decrease in the market price of a long-lived asset or asset group,

•

a significant adverse change in the extent or manner in which a long-lived asset or asset group is being used or in its physical condition,

•

a significant adverse change in legal factors or in the business climate that could affect the value of a long-lived asset or asset group, including an adverse action or assessment by a regulator that would exclude allowable costs from the rate-making process,

•

an accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction of a long-lived asset or asset group,

•

a current-period operating cash flow loss combined with a history of operating cash flow losses or a projection or forecast that demonstrates continuing losses associated with the use of a long-lived asset or asset group, and

•

a current expectation that, more likely than not, a long-lived asset or asset group will be sold or otherwise disposed of significantly before the end of its previously estimated useful life.

In the third quarter of 2005, we made the decision to sell our Spring Creek power plant and exit the power generation business. In October 2005, we concluded that our Spring Creek power plant located in southwest Oklahoma had been impaired and recorded an impairment expense of $52.2 million. This conclusion was based on our Statement 144 impairment analysis of the results of operations for this plant through September 30, 2005, and also the net sales proceeds from the anticipated sale of the plant. These assets were held for sale at September 30, 2005, and, accordingly, this component of our business is accounted for as discontinued operations in accordance with Statement 144.

Significant Accounting Policies

Common Stock Options and Awards - In December 2004, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards No. 123R, “Share-Based Payment” (Statement 123R). Statement 123R requires companies to expense the fair value of share-based payments. In addition, there are also changes related to the expense calculation for share-based payments. Effective January 1, 2006, we will adopt Statement 123R, and we expect to use the prospective method. We are currently assessing the impact of adopting Statement 123R, but we do not believe it will have a material impact on our financial condition and results of operations, as we have been expensing share-based payments since our adoption of Statement of Financial Accounting Standards No. 148, “Accounting for Stock-Based Compensation - Transition and Disclosure” on January 1, 2003.

The following table sets forth the effect on net income and earnings per share if we had applied the fair-value recognition provisions of Statement of Financial Accounting Standards No. 123, “Accounting for Stock-Based Compensation,” to all options and awards granted prior to January 1, 2003.

	*(Thousands of dollars, except per share amounts)*

Pro forma net income	$	184,371	$	20,542	$	316,562	$	142,891

Earnings per share:
Basic - as reported	$	1.85	$	0.20	$	3.12	$	1.42
Basic - pro forma	$	1.85	$	0.20	$	3.12	$	1.41

Diluted - pro forma	$	1.70	$	0.19	$	2.89	$	1.37

Asset Retirement Obligations - In March 2005, the FASB issued Interpretation No. 47, “Accounting for Conditional Asset Retirement Obligations” (FIN 47), that requires an entity to recognize a liability for the fair value of a conditional asset retirement obligation when incurred if the liability’s fair value can be reasonably estimated. FIN 47 is effective for our year ending December 31, 2005. We are currently reviewing the applicability of FIN 47 to our operations and its potential impact on our consolidated financial statements.

Consolidation - In June 2005, the FASB ratified the consensus reached in EITF Issue No. 04-5, “Determining Whether a General Partner, or the General Partners as a Group, Controls a Limited Partnership or Similar Entity When the Limited Partners Have Certain Rights” (EITF 04-5). EITF 04-5 presumes that a general partner controls a limited partnership and therefore should consolidate the partnership. Effective January 1, 2006, we will be required to consolidate Northern Border Partners’ operations in our consolidated financial statements. We are currently evaluating the impact of adopting EITF 04-5. However, had we consolidated Northern Border Partners at September 30, 2005, our debt to equity ratio would have changed from 72 percent debt and 28 percent equity to 78 percent debt and 22 percent equity. This increase results from the consolidation of Northern Border Partners’ debt of $1.3 billion at September 30, 2005, while the majority of their equity is reported as minority interest liability. The debt covenant calculations in our credit agreements exclude the debt of Northern Border Partners since it is a master limited partnership.

Inventory - In September 2005, the FASB ratified the consensus reached in EITF Issue No. 04-13, “Accounting for Purchases and Sales of Inventory with the Same Counterparty” (EITF 04-13). EITF 04-13 defines when a purchase and a sale of inventory with the same party that operates in the same line of business should be considered a single nonmonetary transaction. EITF 04-13 is effective for new arrangements that a company enters into in periods beginning after March 15, 2006. We are currently reviewing the applicability of EITF 04-13 to our operations and its potential impact on our consolidated financial statements.

Other

Reclassifications - Certain amounts in our consolidated financial statements have been reclassified to conform to the 2005 presentation. These reclassifications did not impact previously reported net income or shareholders’ equity. Prior periods have been adjusted to reflect the sale of our Production segment and the pending sale of our Spring Creek power plant as discontinued operations. See Note C for additional information.

B.	Acquisition and Divestiture

On July 1, 2005, we completed the acquisition of the natural gas liquids businesses owned by several affiliates and a subsidiary of Koch Industries, Inc. (Koch) for approximately $1.33 billion, net of working capital and cash received. This transaction includes Koch Hydrocarbon, LP’s entire mid-continent natural gas liquids fractionation business; Koch Pipeline Company, L.P.’s natural gas liquids pipeline distribution systems; Chisholm Pipeline Holdings, Inc., which has a 50 percent ownership interest in Chisholm Pipeline Company; MB1/LP, LLC (formerly MBFF, LP), which owns an 80 percent interest in the 160,000 barrel per day fractionator at Mont Belvieu, Texas; and Koch Vesco Holdings, LLC, an entity that owns a 10.2 percent interest in Venice Energy Services Company, LLC (VESCO). These assets are included in our consolidated financial statements beginning on July 1, 2005.

The unaudited pro forma information in the table below presents a summary of our consolidated results of operations as if the acquisition of the Koch natural gas liquids businesses had occurred at the beginning of the periods presented. The results do not necessarily reflect the results that would have been obtained if the acquisition had actually occurred on the dates indicated or results that may be expected in the future.

We have recorded a preliminary purchase price allocation related to this acquisition. Our Natural Gas Liquids segment has recorded goodwill of approximately $172.0 million and intangibles of approximately $325.6 million. The purchase price allocation will be finalized as additional information regarding the assets acquired becomes available.

In October 2005, we entered into an agreement to sell certain natural gas gathering and processing assets located in Texas to a subsidiary of Eagle Rock Energy, Inc. for approximately $528 million. The transaction is expected to close December 1, 2005, and is subject to Hart-Scott-Rodino antitrust approval. The properties are located in the Texas panhandle and include six gas processing plants, operating at approximately 60 percent of 160 million cubic foot per day capacity with 3,700 miles of gas gathering lines, and estimated natural gas liquids (NGL) production of 13,500 barrels per day. The proceeds from this sale will be used to purchase other assets, repurchase ONEOK shares or retire debt.

C.	Discontinued Operations

In September 2005, we completed the sale of our Production segment to TXOK Acquisition, Inc. for $645 million, before adjustments. We recognized a pre-tax gain on the sale of our Production segment of approximately $243.2 million. The gain reflects the cash received less adjustments, selling expenses and the net book value of the assets sold. The proceeds from the sale were used to reduce debt. Our Board of Directors had approved the potential sale in July 2005, which resulted in our Production segment being classified as held for sale during the third quarter. In accordance with Statement 144, we did not record any depreciation, depletion or amortization for our Production segment while it was classified as held for sale.

Additionally, in the third quarter of 2005, we made the decision to sell our Spring Creek power plant and exit the power generation business. We entered into an agreement to sell our Spring Creek power plant to Westar Energy, Inc. for $53 million. The transaction requires Federal Energy Regulatory Commission (FERC) approval and is expected to be completed in 2006. The 300-megawatt gas-fired merchant power plant was built in 2001 to supply electrical power during peak periods using gas-powered turbine generators. The proceeds from this sale will be used to purchase other assets, repurchase ONEOK shares or retire debt.

These components of our business are accounted for as discontinued operations in accordance with Statement 144, “Accounting for the Impairment or Disposal of Long-Lived Assets.” Accordingly, amounts in our financial statements and related notes for all periods shown relating to our Production segment and our power generation business are reflected as discontinued operations.

The amounts of revenue, costs and income taxes reported in discontinued operations are as follows.

D.	Energy Marketing and Risk Management Activities and Fair Value of Financial Instruments

Accounting Treatment - We account for derivative instruments and hedging activities in accordance with FASB Statement of Financial Accounting Standards No. 133, “Accounting for Derivative Instruments and Hedging Activities” (Statement 133), as amended. Under Statement 133, entities are required to record all derivative instruments at fair value. The accounting for changes in the fair value of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and, if so, the reason for holding it. If the derivative instrument does not qualify or is not designated as part of a hedging relationship, we account for changes in fair value of the derivative instrument in earnings as they occur. If certain conditions are met, entities may elect to designate a derivative instrument as a hedge of exposure to changes in fair values, cash flows or foreign currencies. For hedges of exposure to changes in fair value, the gain or loss on the derivative instrument is recognized in earnings in the period of change together with the offsetting gain or loss on the hedged item attributable to the risk

being hedged. The difference between the change in fair value of the derivative instrument and the change in fair value of the hedged item represents hedge ineffectiveness. For hedges of exposure to changes in cash flow, the effective portion of the gain or loss on the derivative instrument is reported initially as a component of other comprehensive income and is subsequently reclassified into earnings when the forecasted transaction affects earnings. Any amounts excluded from the assessment of hedge effectiveness, as well as the ineffective portion of the hedge, are reported in earnings.

As required by Statement 133, we formally document all relationships between hedging instruments and hedged items, as well as risk management objectives, strategies for undertaking various hedge transactions and methods for assessing and testing correlation and hedge ineffectiveness. We specifically identify the asset, liability, firm commitment or forecasted transaction that has been designated as the hedged item and assess the effectiveness of hedging relationships, both at the inception of the hedge and on an ongoing basis.

At the beginning of the third quarter of 2004, we completed a reorganization of our Energy Services segment and renewed our focus on our physical marketing and storage business. Concurrent with this reorganization, we evaluated the accounting treatment related to the presentation of revenues from the different types of activities to determine which amounts should be reported on a gross or net basis. We began accounting for the realized revenues and purchase costs of those contracts that result in physical delivery on a gross basis beginning in the third quarter of 2004. Derivatives that qualify for the normal purchase or sale exception as defined in Statement 133 are also reported on a gross basis. No prior periods have been adjusted for this change; therefore, comparisons with prior periods may not be meaningful. Reporting of these transactions on a gross basis did not impact operating income, but resulted in an increase to revenues and cost of sales and fuel.

Refer to Note D of the Notes to Consolidated Financial Statements in our Annual Report on Form 10-K for the year ended December 31, 2004, for additional discussion.

Fair Value Hedges

During the first quarter of 2005, we terminated $400 million of our interest rate swap agreements and paid a net amount of $19.4 million, which included $20.2 million for the present value of future payments at the time of termination, less $0.8 million for interest rate savings through the termination of the swaps. During the first quarter of 2004, we terminated $670 million of our interest rate swap agreements and received $81.9 million. The net savings from the termination of these swaps is being recognized in interest expense over the terms of the debt instruments originally hedged. Net interest expense savings for the first nine months of 2005 for all terminated swaps was $5.9 million, and the remaining net savings for all terminated swaps will be recognized over the following periods:


Remainder of 2005	$	1.7 million
2006	$	6.8 million
2007	$	6.6 million
2008	$	6.6 million
2009	$	5.6 million
Thereafter	$	20.8 million

Currently, $340 million of our fixed-rate debt is swapped to floating. The floating rate debt is based on both the three- and six-month London InterBank Offered Rate (LIBOR), depending upon the swap. At September 30, 2005, we recorded a net liability of $5.4 million to recognize the interest rate swaps at fair value. Long-term debt was decreased by $5.4 million to recognize the change in the fair value of the related hedged liability.

Our Energy Services segment uses basis swaps to hedge the fair value of certain firm transportation commitments. Net gains or losses from the fair value hedges are recorded as cost of sales and fuel. The ineffectiveness related to these hedges was $1.7 million and $1.4 million for the three and nine months ended September 30, 2005, respectively. The ineffectiveness related to these hedges was immaterial for the three and nine months ended September 30, 2004.

Cash Flow Hedges

Our Energy Services segment uses futures and swaps to hedge the cash flows associated with our anticipated purchases and sales of natural gas and cost of fuel used in transportation of gas. Accumulated other comprehensive loss at September 30, 2005, includes net losses of approximately $259.5 million, net of tax, related to these hedges that will be realized within the next 44 months. We will recognize $174.3 million in net losses over the next 12 months, and we will recognize net losses of $85.2 million thereafter. Our Gathering and Processing segment periodically enters into derivative instruments to hedge the cash flows

associated with our exposure to changes in the price of natural gas, NGLs and crude oil. Accumulated other comprehensive loss at September 30, 2005, which includes net losses of approximately $5.7 million, net of tax, related to these hedges, will be realized in the income statement primarily within the next 12 months. Our Natural Gas Liquids segment utilizes swaps to hedge our exposure to changes in the price of NGLs. Accumulated other comprehensive loss at September 30, 2005, which includes net losses of approximately $0.9 million, net of tax, related to these swaps, will be realized in the income statement in December 2005. These losses will be partially offset by the gains on the related physical sales that will be recognized in earnings at the time the derivative instruments are settled.

Net gains and losses are reclassified out of accumulated other comprehensive loss to operating revenues or cost of sales and fuel when the anticipated purchase or sale occurs. Ineffectiveness related to these cash flow hedges was a loss of approximately $7.0 million and a loss of approximately $7.1 million for the three and nine months ended September 30, 2005, respectively. Ineffectiveness related to these cash flow hedges for the three and nine months ended September 30, 2004, resulted in a gain of approximately $0.1 million and a loss of approximately $4.0 million, respectively. Additionally, losses of approximately $4.6 million were recognized from accumulated other comprehensive loss during the nine months ended September 30, 2004, due to the discontinuance of cash flow hedge treatment on certain transactions since it was probable that the forecasted transactions would not occur.

Our Distribution segment also uses derivative instruments from time to time. Gains or losses associated with these derivative instruments are included in, and recoverable through, the monthly purchased gas adjustment. At September 30, 2005, Kansas Gas Service had derivative instruments in place to hedge the cost of natural gas purchases for 8.9 Bcf, which represents part of its gas purchase requirements for the 2005/2006 winter heating months.

Prior to the issuance of the $800 million of notes in the second quarter of 2005, we entered into $500 million in treasury rate-lock agreements to hedge the changes in cash flows of our anticipated interest payments from changes in treasury rates prior to the issuance of the notes. Upon issuance of the notes in June 2005, the treasury rate-lock agreements terminated, which resulted in us paying $2.4 million. This amount, net of tax, has been recorded as accumulated other comprehensive loss and will be recognized in the income statement over the term of the related debt issuances.

E.	Regulatory Assets

The following table is a summary of regulatory assets, net of amortization, for the periods indicated.


	September 30, 2005		December 31, 2004
	*(Thousands of dollars)*
Recoupable take-or-pay	$	54,015	$	58,412

Service lines		—		1,517
Other		5,944		7,964

Regulatory assets, net	$	187,455	$	203,547

We amortize reacquired debt costs in accordance with the accounting rules prescribed by the Oklahoma Corporation Commission (OCC) and Kansas Corporation Commission (KCC). These costs were included as a component of interest in the rate order issued by the OCC on October 4, 2005, and were included in a previous rate order issued by the KCC.

The remaining amount of regulatory assets, net is being recovered through various rate cases with the exception of an immaterial amount, which we expect to eventually recover.

F.	Goodwill

In July 2005, we acquired the natural gas liquids businesses owned by Koch for approximately $1.33 billion, net of working capital and cash received. See Note B for additional information regarding this acquisition. The acquisition increased our mid-continent operating focus through a downstream extension of our natural gas gathering and processing operation. The assets acquired provide commercial, operational and administrative synergies as these assets enhance our existing mid-stream operating areas. This acquisition creates new and expanded commercial opportunities and we anticipate volumes and margins of our existing business to increase. Our gathering and processing assets were the second largest producer of NGLs on the system and all but one of our processing plants is connected to the system. Additionally, the acquisition improves our market access to the largest NGL hub, which is located in the gulf coast. As a result of our preliminary purchase price allocation, we assigned $1.2 billion to identifiable assets consisting of approximately $912.7 million to tangible assets based on the fair value of the net assets and approximately $325.6 million to identifiable intangible assets that will be amortized on a straight-line basis over the remaining useful lives of the assets, as determined by underlying contract terms or third-party appraisals. The excess of the purchase price over the fair value of identifiable assets acquired, net of liabilities assumed is $172.0 million which is recorded as goodwill.

The following table reflects the changes in the carrying amount of goodwill for the periods indicated.


	Balance December 31, 2004		Goodwill Acquired		Balance September 30, 2005

G.	Intangibles

Intangible assets primarily relate to contracts acquired through the acquisition of the natural gas liquids businesses from Koch and based on the preliminary purchase price allocation are being amortized over our aggregate weighted-average period of 40 years. See Notes B and F for additional information regarding the acquisition that resulted in intangible assets. The aggregate amortization expense for each of the next five years is estimated to be approximately $8.1 million. The following tables reflect the gross carrying amount and accumulated amortization of intangibles at September 30, 2005.

Accumulated other comprehensive loss at September 30, 2005 and 2004, primarily includes unrealized gains and losses on derivative instruments and minimum pension liability adjustments.

I.	Capital Stock

Stock Repurchase Plan - During the third quarter of 2005, we repurchased approximately 2.3 million shares of our common stock pursuant to a plan approved by our Board of Directors on January 20, 2005, bringing the total repurchased under the plan to 6.0 million shares. This plan allows us to purchase up to a total of 7.5 million shares of our common stock on or before January 20, 2007.

Dividends - Quarterly dividends paid on our common stock for shareholders of record as of the close of business on January 31, 2005, May 2, 2005, and July 29, 2005, were $0.25 per share, $0.28 per share and $0.28 per share, respectively. Additionally, a quarterly dividend of $0.28 per share was declared in September, payable in the fourth quarter of 2005.

J.	Lines of Credit and Short-Term Notes Payable

In June 2005, we entered into a $1.0 billion short-term bridge financing agreement. The interest rate is based, at our election, on either (i) the higher of prime or one-half of one percent above the Federal Funds Rate or (ii) the Eurodollar rate plus a set number of basis points based on our current long-term unsecured debt ratings by Moody’s Investors Service and Standard and Poor’s.

On July 1, 2005, we borrowed $1.0 billion under the short-term bridge financing agreement to assist in financing the acquisition of assets from Koch. See Note B for additional information about this acquisition. We funded the remaining acquisition cost through our commercial paper program. We anticipate permanent financing of the acquisition to come from a combination of proceeds from the sale of assets, such as our Production segment, our natural gas gathering and processing assets located in Texas and our Spring Creek power plant, proceeds from the February 2006 settlement of the purchase contracts that are part of our mandatory convertible equity units, and free cash flow. At September 30, 2005, we had lowered the commitment of outstanding indebtedness under the bridge financing agreement to $900.0 million. The reduction in indebtedness under our short-term bridge financing agreement is a result of a required prepayment due to the sale of our Production segment.

In July 2005, we amended our 2004 $1.0 billion five-year credit agreement to increase the limit on our debt-to-equity ratio from 67.5 percent debt to 70 percent debt for the period from July 25, 2005, to February 28, 2006. Beginning on March 1, 2006, the limit on our debt will return to 67.5 percent of total capital.

In September 2005, we exercised the accordion feature of our 2004 $1.0 billion five-year credit agreement to increase the commitment amounts by $200 million to a total of $1.2 billion. The interest rate payable under this five-year credit agreement is a floating rate calculated in the same manner as the $1.0 billion short-term bridge financing agreement. Additionally, we amended the five-year credit and the short-term bridge financing agreements to change the definition of Consolidated Net Worth to eliminate the effect of gains and losses recorded in accumulated other comprehensive income (loss) as a result of certain commodity hedging agreements. The effect of these amendments was to increase the amount of indebtedness we can incur while maintaining compliance with the covenants in those agreements that limit our debt-to-equity ratio.

Both the five-year credit agreement and short-term bridge financing agreement contain customary affirmative and negative covenants, including covenants relating to liens, investments, fundamental changes in our business, changes in the nature of our business, transactions with affiliates, the use of proceeds, a limit on our debt-to-equity ratio, a limit on investments in master limited partnerships and a covenant that prevents us from restricting our subsidiaries’ ability to pay dividends to ONEOK, Inc. At September 30, 2005, we were in compliance with all covenants.

We had $168.7 million in letters of credit outstanding at September 30, 2005.

K.	Long-Term Debt

We had 16.1 million mandatory convertible equity units outstanding at September 30, 2005. Each unit consists of two components, an equity purchase contract and a note (see Notes H and J of Notes to Consolidated Financial Statements in our 2004 Form 10-K for additional information). In November 2005, we will seek to remarket the notes and any cash received will be put into a treasury portfolio pledged as collateral against the purchase contracts. This action will have no effect on our liquidity. In February 2006, the purchase contracts require the holders of the mandatory convertible equity units to purchase our common stock. If the notes are successfully remarketed, we will receive $402.5 million and issue common shares of stock, the number of which will depend upon the average closing price of our common stock for the 20 trading days prior to the date of issuance. For more information, refer to our Prospectus Supplement dated January 23, 2003.

In June 2005, we issued $800 million of notes, comprised of $400 million in 10-year maturities with a coupon of 5.2 percent and $400 million in 30-year maturities with a coupon of 6.0 percent. The notes were issued under our shelf registration statement dated April 15, 2003. Proceeds from this debt issuance were used to repay commercial paper borrowings and for general corporate purposes.

In March 2005, we had $335 million of long-term debt mature. We funded payment of this debt with working capital and the issuance of commercial paper in the short-term market.

Contributions - Contributions of $1.0 million and $12.3 million were made to our pension plan and other postretirement benefit plan, respectively, for the nine months ended September 30, 2005. We presently anticipate our total 2005 contributions to be $1.8 million for the pension plan and $16.1 million for the other postretirement benefit plan.

M.	Commitments and Contingencies

Environmental - We are subject to multiple environmental laws and regulations affecting many aspects of present and future operations, including air emissions, water quality, wastewater discharges, solid wastes and hazardous material and substance management. These laws and regulations generally require us to obtain and comply with a wide variety of environmental registrations, licenses, permits, inspections and other approvals. Failure to comply with these laws, regulations, permits and licenses may expose us to fines, penalties and/or interruptions in our operations that could be material to the results of operations. If an accidental leak or spill of hazardous materials occurs from our lines or facilities in the process of transporting natural gas or NGLs or at any facility that we own, operate or otherwise use, we could be held jointly and severally liable for all resulting liabilities, including investigation and clean-up costs, which could materially affect our results of operations and cash flow. In addition, emission controls required under the Federal Clean Air Act and other similar federal and state laws could require unexpected capital expenditures at our facilities. We cannot assure that existing environmental regulations will not be revised or that new regulations will not be adopted or become applicable to us. Revised or additional regulations that result in increased compliance costs or additional operating restrictions, particularly if those costs are not fully recoverable from customers, could have a material adverse effect on our business, financial condition and results of operations.

We own or retain legal responsibility for the environmental conditions at 12 former manufactured gas sites in Kansas. Our expenditures for environmental evaluation and remediation to date have not been significant in relation to the results of operations, and there have been no material effects upon earnings during 2005 related to compliance with environmental regulations. See Note L in our Annual Report on Form 10-K for the year ended December 31, 2004, for additional discussion. There has been no material change to the status of the manufactured gas sites since December 31, 2004.

Yaggy Facility - The two class action lawsuits filed against us in connection with the natural gas explosions and eruptions of natural gas geysers that occurred at, and in the vicinity of, our Yaggy facility in January 2001, resulted in jury verdicts in September 2004. The jury awarded the plaintiffs in the residential class $5.0 million in actual damages, and the judge ordered the payment of $2.0 million in attorney fees and $0.6 million in expenses, all of which are covered by insurance. In the other class action relating to business claims, the jury awarded no damages. The jury rejected claims for punitive damages in both cases. On April 11, 2005, the court denied the plaintiffs’ motion for a new trial and denied a post-trial motion filed by defendants. We filed our notice of appeal of the residential class verdict and the attorney fee award. The cases have now been transferred to the Kansas Supreme Court for appeal. With the exception of appeals, all litigation regarding our Yaggy facility has been resolved.

Other - We are a party to other litigation matters and claims, which are normal in the course of our operations. While the results of litigation and claims cannot be predicted with certainty, we believe the final outcome of such matters will not have a material adverse effect on our consolidated results of operations, financial position or liquidity.

N.	Segments

Our business segments and the accounting policies of our business segments are the same as those described in Note N and the Summary of Significant Accounting Policies in our Annual Report on Form 10-K for the year ended December 31, 2004, with the exception of the segments described below. Our Distribution segment is comprised of regulated public utilities. Intersegment gross sales are recorded on the same basis as sales to unaffiliated customers. Corporate overhead costs relating to a reportable segment have been allocated for the purpose of calculating operating income. Our equity method investments do not represent operating segments. We have no single external customer from which we received 10 percent or more of our consolidated gross revenues for the periods covered by this report.

In September 2005, we completed the sale of our Production segment. Additionally, in the third quarter of 2005, we made the decision to sell our Spring Creek power plant and exit the power generation business. These components of our business are accounted for as discontinued operations in accordance with Statement 144. Our Production segment is included in the Other segment in the tables below, while our power generation business is included in our Energy Services segment.

With the acquisition of assets from Koch on July 1, 2005, we formed a new operating segment called Natural Gas Liquids. This segment consists of our existing natural gas liquids marketing business, which was previously part of our Gathering and Processing segment, and the assets acquired from Koch excluding those natural gas liquids gathering and pipeline distribution assets regulated by the FERC, which have been transferred to our Pipelines and Storage segment. VESCO, also acquired as part of the asset acquisition, was added to our Gathering and Processing segment.

Segment results for the Gathering and Processing segment for all prior periods have been restated to reflect the transfer of our existing natural gas liquids marketing business to the Natural Gas Liquids segment. The segment formerly named Transportation and Storage has been renamed Pipelines and Storage in order to better describe the activities of the segment.

As discussed in Note D, at the beginning of the third quarter of 2004, we completed a reorganization of our Energy Services segment. We began accounting separately for the different types of revenue earned from these activities, with certain revenues accounted for on a gross rather than a net basis.

The following tables set forth certain selected financial information for our operating segments for the periods indicated.

For the nine months ended September 30, 2005, and 2004, there were 48,062 and 14,711 option shares, respectively, excluded from the calculation of diluted EPS since their inclusion would be antidilutive for each period.

Item 2.

Management’s Discussion and Analysis of Financial Condition and Results of Operations

Executive Summary - Operating income for our third quarter of 2005 was $123.2 million, an increase of $74.8 million, or 155 percent, compared with the same period in 2004. For the first nine months of 2005, operating income was $361.7 million, an increase of $87.5 million, or 32 percent, from the same period last year.

Diluted earnings per share of common stock from continuing operations (EPS) increased to 49 cents for the third quarter of 2005 from 15 cents for the same period in 2004. For the nine-month period, EPS increased to $1.56 for 2005 from $1.25 in 2004.

Our Energy Services segment benefited from increases in natural gas prices and volatility during the third quarter of 2005. An increase of $54.6 million and $29.6 million for the three- and nine-month periods, respectively, was due to storage and transportation activities primarily attributable to opportunities to realize higher margins from selling natural gas from storage due to increases in natural gas prices and volatility, and gains associated with the increase in basis spreads on financial instruments used to hedge purchases and sales associated with storage activities.

Favorable energy prices also had a significant impact on our Gathering and Processing segment’s results during the nine-month period for 2005. Average prices for natural gas, natural gas liquids (NGLs) and crude oil exceeded prices for the same period in 2004. The gross processing spread was also higher in 2005 and continued to exceed the previous five-year average. The effect of these higher prices increased our Gathering and Processing segment’s operating income 16 percent for the quarter and 41 percent for the nine-month period, compared with the same periods in 2004.

On July 1, 2005, we completed the acquisition of the natural gas liquids businesses owned by several affiliates and a subsidiary of Koch Industries, Inc. (Koch). The results of operations for these acquired assets accounted for increases in both our Natural Gas Liquids segment and our Pipelines and Storage segment.

On October 4, 2005, the Oklahoma Corporation Commission (OCC) issued a final order on our application for a rate increase by Oklahoma Natural Gas. The OCC unanimously approved an annual rate increase of $57.5 million. In July, the Commission’s administrative law judge recommended an increase in annual revenues of approximately $58.0 million. Oklahoma Natural Gas implemented new rates, subject to refund, on July 28, 2005, based on the judge’s report.

Discontinued Operations - In September 2005, we completed the sale of our Production segment to TXOK Acquisition, Inc. for $645 million, before adjustments. We recognized a pre-tax gain on the sale of the discontinued component for our Production segment of approximately $243.2 million. The gain reflects the cash received less adjustments, selling expenses and the net book value of the assets sold. The proceeds from the sale were used to reduce debt.

Additionally, in the third quarter of 2005 we made the decision to sell our Spring Creek power plant and exit the power generation business. In October 2005, we concluded that our Spring Creek power plant located in southwest Oklahoma had been impaired and recorded an impairment expense of $52.2 million. This conclusion was based on our impairment analysis of the results of operations for this plant through September 30, 2005, and also considered net sales proceeds from a sale of the plant. In October 2005, we entered into an agreement to sell our Spring Creek power plant to Westar Energy, Inc. for $53 million. The transaction requires Federal Energy Regulatory Commission (FERC) approval and is expected to be completed in 2006. The 300-megawatt gas-fired merchant power plant was built in 2001 to supply electrical power during peak periods using gas-powered turbine generators. The proceeds from this sale will be used to purchase other assets, repurchase ONEOK shares or retire debt.

These components of our business are accounted for as discontinued operations in accordance with Statement of Financial Accounting Standards No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets” (Statement 144). Accordingly, amounts in our financial statements and related notes for all periods shown relating to our Production segment and our power generation business are reflected as discontinued operations. The sale of our Production segment and the pending sale of our power generation business are in line with our business strategy to sell assets when deemed less strategic or as other conditions warrant.

Acquisition - On July 1, 2005, we completed the acquisition of the natural gas liquids businesses owned by Koch for approximately $1.33 billion, net of working capital and cash received. This transaction includes Koch Hydrocarbon, LP’s entire mid-continent natural gas liquids fractionation business; Koch Pipeline Company, L.P.’s natural gas liquids pipeline distribution systems; Chisholm Pipeline Holdings, Inc., which has a 50 percent ownership interest in Chisholm Pipeline Company; MB1/LP, LLC (formerly MBFF, LP), which owns an 80 percent interest in the 160,000 barrel per day fractionator at Mont Belvieu, Texas;

and Koch Vesco Holdings, LLC, an entity that owns a 10.2 percent interest in Venice Energy Services Company, LLC (VESCO). These assets are included in our consolidated financial statements beginning on July 1, 2005.

The acquisition was initially financed through our $1.0 billion short-term bridge financing agreement, which we entered into in June 2005, and our commercial paper program. We anticipate permanent financing of the acquisition to come from a combination of the proceeds from the settlement of our mandatory convertible equity units in February 2006, proceeds from the sale of less strategic assets and free cash flow.

Divestiture - In October 2005, we entered into an agreement to sell certain natural gas gathering and processing assets located in Texas to a subsidiary of Eagle Rock Energy, Inc. for approximately $528 million. The transaction is expected to close December 1, 2005, and is subject to Hart-Scott-Rodino antitrust clearance. The properties are located in the Texas panhandle and include six gas processing plants, operating at approximately 60 percent of 160 million cubic foot per day capacity with 3,700 miles of gas gathering lines, and estimated NGL production of 13,500 barrels per day. The proceeds from this sale will be used to purchase other assets, repurchase ONEOK shares or retire debt.

Regulatory - Several regulatory initiatives positively impacted the earnings and future earnings potential for our Distribution segment. These initiatives are discussed beginning on page 41.

Impact of New Accounting Standards - In December 2004, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards No. 123R, “Share-Based Payment” (Statement 123R). Statement 123R requires companies to expense the fair value of share-based payments. In addition, there are also changes related to the expense calculation for share-based payments. Effective January 1, 2006, we will adopt Statement 123R, and we expect to use the prospective method. We are currently assessing the impact of adopting Statement 123R, but we do not believe it will have a material impact on our financial condition and results of operations, as we have been expensing share-based payments since our adoption of Statement of Financial Accounting Standards No. 148, “Accounting for Stock-Based Compensation - Transition and Disclosure” on January 1, 2003.

In March 2005, the FASB issued Interpretation No. 47, “Accounting for Conditional Asset Retirement Obligations” (FIN 47), that requires an entity to recognize a liability for the fair value of a conditional asset retirement obligation when incurred if the liability’s fair value can be reasonably estimated. FIN 47 is effective for our year ending December 31, 2005. We are currently reviewing the applicability of FIN 47 to our operations and its potential impact on our consolidated financial statements.

In June 2005, the FASB ratified the consensus reached in EITF Issue No. 04-5, “Determining Whether a General Partner, or the General Partners as a Group, Controls a Limited Partnership or Similar Entity When the Limited Partners Have Certain Rights” (EITF 04-5). EITF 04-5 presumes that a general partner controls a limited partnership and therefore should consolidate the partnership. Effective January 1, 2006, we will be required to consolidate Northern Border Partners’ operations in our consolidated financial statements. We are currently evaluating the impact of adopting EITF 04-5. However, had we consolidated Northern Border Partners at September 30, 2005, our debt to equity ratio would have changed from 72 percent debt and 28 percent equity to 78 percent debt and 22 percent equity. This increase results from the consolidation of Northern Border Partners’ debt of $1.3 billion at September 30, 2005, while their equity is reported as minority interest in partners’ equity. The debt covenant calculations in our credit agreements exclude the debt of Northern Border Partners, since it is a master limited partnership.

In September 2005, the FASB ratified the consensus reached in EITF Issue No. 04-13, “Accounting for Purchases and Sales of Inventory with the Same Counterparty” (EITF 04-13). EITF 04-13 defines when a purchase and a sale of inventory with the same party that operates in the same line of business should be considered a single nonmonetary transaction. EITF 04-13 is effective for new arrangements that a company enters into in periods beginning after March 15, 2006. We are currently reviewing the applicability of EITF 04-13 to our operations and its potential impact on our consolidated financial statements.

Critical Accounting Policies and Estimates

Derivatives and Risk Management Activities - We engage in wholesale energy marketing, retail marketing, trading and risk- management activities. We account for derivative instruments utilized in connection with these activities and services under the fair value basis of accounting in accordance with Statement of Financial Accounting Standards No. 133, “Accounting for Derivative Instruments and Hedging Activities” (Statement 133), as amended.

Under Statement 133, entities are required to record derivative instruments at fair value. The fair value of derivative instruments is determined by commodity exchange prices, over-the-counter quotes, volatility, time value, counterparty credit and the potential impact on market prices of liquidating positions in an orderly manner over a reasonable period of time under current market conditions. Refer to the table on page 47 for amounts in our portfolio at September 30, 2005, that were determined by prices actively quoted, prices provided by other external sources and prices derived from other sources. The majority of our portfolio’s fair value is based on actual market prices. Transactions are also executed in markets for which market prices may exist but the market may be relatively inactive, thereby resulting in limited price transparency that requires management’s subjectivity in estimating fair values.

Market value changes result in a change in the fair value of our derivative instruments. The accounting for changes in the fair value of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and, if so, the reason for holding it. If the derivative instrument does not qualify or is not designated as part of a hedging relationship, we account for changes in fair value of the derivative in earnings as they occur. Commodity price volatility may have a significant impact on the gain or loss in any given period. For more information on fair value sensitivity and a discussion of the market risk of pricing changes, see Item 3, Quantitative and Qualitative Disclosures About Market Risk.

To minimize the risk of fluctuations in natural gas, NGLs and crude oil prices, we periodically enter into derivative transactions to hedge anticipated sales and purchases of natural gas, NGLs, crude oil, fuel requirements and transportation firm commitments. Interest rate swaps are also used to manage interest rate risk. Under certain conditions, we designate these derivative instruments as a hedge of exposure to changes in fair value or cash flows. For hedges of exposure to changes in fair value, the gain or loss on the derivative instrument is recognized in earnings in the period of change together with the offsetting gain or loss on the hedged item attributable to the risk being hedged. For hedges of exposure to changes in cash flow, the effective portion of the gain or loss on the derivative instrument is reported initially as a component of other comprehensive income and is subsequently reclassified into earnings when the forecasted transaction affects earnings. Any ineffectiveness of designated hedges is reported in earnings in the period incurred.

Many of our purchase and sale agreements that otherwise would be required to follow derivative accounting qualify as normal purchases and normal sales under Statement 133 and are therefore exempt from fair value accounting treatment. Energy-related contracts that are not derivatives pursuant to Statement 133 are accounted for on an accrual basis as executory contracts.

Impairment of Goodwill and Long-Lived Assets - We assess our goodwill for impairment at least annually based on Statement of Financial Accounting Standards No. 142, “Goodwill and Other Intangible Assets” (Statement 142). An initial assessment is made by comparing the fair value of each reporting unit with goodwill, as determined in accordance with Statement 142, to the book value of the reporting unit. If the fair value is less than the book value, an impairment is indicated and we must perform a second test to measure the amount of the impairment. In the second test, we calculate the implied fair value of the goodwill by deducting the fair value of all tangible and intangible net assets of the operations with goodwill from the fair value determined in step one of the assessment. If the carrying value of the goodwill exceeds this calculated implied fair value of the goodwill, we will record an impairment charge. We completed our annual analysis of goodwill for impairment as of January 1, 2005, and there was no impairment indicated. At September 30, 2005, we had $397.2 million of goodwill recorded on our balance sheet.

We assess our long-lived assets for impairment based on Statement 144. A long-lived asset is tested for impairment whenever events or changes in circumstances indicate that its carrying amount may exceed its fair value. Fair values are based on the sum of the undiscounted future cash flows expected to result from the use and eventual disposition of the assets.

Examples of long-lived asset impairment indicators include:

a significant decrease in the market price of a long-lived asset or asset group,

•

a significant adverse change in the extent or manner in which a long-lived asset or asset group is being used or in its physical condition,

•

an accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction of a long-lived asset or asset group,

•

a current expectation that, more likely than not, a long-lived asset or asset group will be sold or otherwise disposed of significantly before the end of its previously estimated useful life.

We do not currently anticipate any additional goodwill or asset impairments to occur within the next year, but if such events were to occur over the long-term, the impact could be significant to our financial condition and results of operations.

Pension and Postretirement Employee Benefits - We have a defined benefit pension plan covering substantially all full-time employees and a postretirement employee benefits plan covering some employees. Our actuarial consultant calculates the expense and liability related to these plans and uses statistical and other factors that attempt to anticipate future events. These factors include assumptions about the discount rate, expected return on plan assets, rate of future compensation increases, age and employment periods. In determining the projected benefit obligations and the costs, assumptions can change from period to period and result in material changes in the costs and liabilities we recognize.

We use September 30 as the measurement date for our annual actuarial study related to our defined benefit pension plan and our postretirement benefit plan. We currently anticipate using a discount rate of 5.75 percent to estimate our 2006 expense and liability related to these plans. We have not completed our current actuarial study, however, the impact of using a discount rate of 5.75 percent, compared to 6.00 percent in our prior year study, will generally cause our expense for 2006 to increase compared to our expense recorded for 2005.

During 2004, we recorded net periodic benefit costs of $0.9 million related to our defined benefit pension plan and $25.0 million related to postretirement benefits. We estimate that in 2005 we will record net periodic benefit costs of $13.0 million related to our defined benefit pension plan and $27.4 million related to postretirement benefits. These increases primarily relate to Northern Plains’, our subsidiary which provides services to Northern Borders Partners, amendments in benefits payable under our gas union contracts and a change in our assumed discount rate. See Note L of Notes to Consolidated Financial Statements in this Form 10-Q.

Contingencies - Our accounting for contingencies covers a variety of business activities, including contingencies for legal exposures and environmental exposures. We accrue these contingencies when our assessments indicate that it is probable that a liability has been incurred or an asset will not be recovered and an amount can be reasonably estimated in accordance with Statement of Financial Accounting Standards No. 5, “Accounting for Contingencies.” We base our estimates on currently available facts and our estimates of the ultimate outcome or resolution. Actual results may differ from our estimates resulting in an impact, positive or negative, on earnings.

For further discussion of our accounting policies, see Note A of Notes to the Consolidated Financial Statements in this Form 10-Q.

Operating Results - Net margin increased for the three and nine months ended September 30, 2005, compared with the same periods in 2004 primarily due to:

•

the effect of increased natural gas prices and higher volatility in our Energy Services segment,

•

the effect of the natural gas liquids assets acquired from Koch in our Natural Gas Liquids segment and our Pipelines and Storage segment,

•

the favorable commodity pricing for natural gas and NGL products on our Gathering and Processing segment, and

•

the implementation of new rate schedules in Oklahoma for our Distribution segment.

For an explanation of energy trading revenues, net, see the discussion of our Energy Services segment beginning on page 36.

Consolidated operating costs increased for the three- and nine-month periods primarily due to the costs related to the natural gas liquids assets acquired from Koch and increased employee benefit costs.

Depreciation, depletion and amortization increased for the three- and nine-month periods primarily due to the costs associated with the natural gas liquids assets acquired from Koch. Additionally, depreciation, depletion and amortization increased for the nine-month period due to a charge related to the replacement of our customer service system in Texas and regulatory asset amortization resulting from the Kansas rate case, both in our Distribution segment.

Gathering and Processing

Overview - Our Gathering and Processing segment is engaged in the gathering and processing of natural gas and fractionation of NGLs primarily in Oklahoma, Kansas and Texas. We own approximately 13,900 miles of gathering pipelines that supply our gas processing plants. We have active processing capacity of approximately 1.8 Bcf/d and NGL fractionation capacity of 89 MBbls/d.

Our operations include the gathering of natural gas production from oil and natural gas wells. Through gathering systems, these volumes are aggregated into sufficient volumes to be processed to remove water vapor, solids and other contaminants and to extract NGLs in order to provide marketable natural gas, commonly referred to as residue gas. When the liquids are separated from the raw natural gas at the processing plants, the liquids are generally in the form of a mixed NGL stream. Some of this stream is then separated by a distillation process, referred to as fractionation, into component products (ethane, propane, isobutane, normal butane and natural gasoline) by company-owned fractionation facilities. The component products can then be stored, transported and/or marketed to a diverse customer base of end users.

We generally gather and process gas under three types of contracts:

•

Keep Whole - We extract NGLs and return to the producer volumes of merchantable natural gas containing the same amount of Btus as the raw natural gas that the producer delivered to us.

•

Percent of Proceeds (POP) - We retain a percentage of the NGLs and/or a percentage of the natural gas as payment for gathering, compressing and processing the producer’s raw natural gas.

•

Fee - We are paid a fee for the services provided such as Btus gathered, compressed, treated and/or processed.

Contracts covering approximately 29 percent of the volumes associated with our keep whole contracts allow us to charge conditioning fees for processing, in the event the keep whole spread is negative. This helps mitigate the impact of an unfavorable keep whole spread by effectively converting a keep whole contract to a fee contract during periods of negative keep whole spread. Our effort to add this conditioning language is a strategy that we continue to execute. We are also continuing our strategy of renegotiating any under-performing gas purchase and gathering contracts.

Additionally, we have the ability to adjust plant operations to take advantage of market conditions. By changing the temperatures and pressures at which the gas is processed, we can produce more of the specific commodities that have the most favorable prices or price spread.

We are impacted by producer drilling activity, which is sensitive to geological success as well as availability of capital and commodity prices. The mid-continent region is currently experiencing a significant upturn in oil and gas drilling activity. This resurgence in drilling activity has been driven by increased prices for natural gas, crude oil and by the long-term projections of continued demand for natural gas. We are exposed to volume risk from both a competitive and a production standpoint. We continue to see production declines in certain fields that supply our gathering and processing operations, and the possibility exists that declines may surpass development from new drilling.

For more discussion of our gathering and processing operations, including factors that affect our ability to compete, see our Form 10-K for the year ended December 31, 2004.

Acquisition - The following acquisition is discussed beginning on page 25.

•

On July 1, 2005, we acquired Koch Vesco Holdings, LLC, an entity which owns a 10.2 percent interest in Venice Energy Services Company, LLC (VESCO). VESCO owns a gas processing complex near Venice, Louisiana.

Operating Results - The financial and operating results above have been restated to reflect the transfer of the natural gas liquids marketing business that was previously included in our Gathering and Processing segment to our new Natural Gas Liquids segment.

The increase in net margin for the three month period is primarily due to an increase of $8.3 million attributable to higher natural gas and NGL prices on our POP contracts, net of hedging activities. This increase was offset by a decrease of $1.5 million due to less volume processed as a result of natural production declines and contract expirations.

The increase in net margin for the nine months ended September 30, 2005, compared with the same periods for 2004, is primarily due to:

•

an increase of $21.5 million due to higher natural gas and NGL prices on our POP contracts, net of hedges,

•

an increase of $12.0 million attributable to our keep whole contracts due primarily to an increase in our gross processing spread, net of hedging, and

•

an increase of $6.1 million due primarily to natural gas volume increases as certain natural gas producers elected to convert their contracts from keep whole to either fee or POP.

The gross processing spread for the three and nine months ended September 30, 2005, which is the relative difference in economic value between NGLs and natural gas on a Btu basis, was higher than the previous five-year average of $1.78. The gross processing spread in the third quarter of 2005 was $3.62 per MMBtu versus $3.07 per MMBtu in the third quarter of 2004; however, it had a minimal impact on margins because of hedging activities. Improved contractual terms for gas gathering and processing resulting from our continued efforts to renegotiate under-performing gas purchase, gas processing and gathering contracts, continue to positively impact net margin.

The increase in operating costs for both the three- and nine-month periods is primarily due to an increase of $0.6 million and $1.7 million, respectively, in materials, supplies and utilities related to compressor utilization and maintenance. The remaining increase is associated with higher employee-related costs.

The decrease in other income (expense) for both the three- and nine-month periods is partially due to the accrual of a $0.5 million insurance deductible associated with VESCO. The Venice, Louisiana plant suffered damage in August 2005 from Hurricane Katrina and is not currently operating. Management expects that insurance payments from our carriers will cover the remaining costs associated with repairing the damage to the facility. The facility is currently expected to be repaired and back in service during the first quarter of 2006.

The increase in capital expenditures for the nine-month period is primarily related to additional compression expenditures and growth activities.

In October 2005, we entered into an agreement to sell certain natural gas gathering and processing assets located in Texas. See page 26 for additional information. The impact of these assets on our Gathering and Processing segment’s operating income for the three and nine months ended September 30, 2005, was $14.0 million and $32.5 million, respectively.

Risk Management - We use derivative instruments to minimize the risks associated with price volatility. The realized financial impact of the derivative transactions is included in our operating income in the period that the physical transaction occurs.

The following tables set forth our remaining 2005 and 2006 hedging information for our Gathering and Processing segment.

Natural Gas Liquids

Overview - Our Natural Gas Liquids segment primarily gathers, fractionates and treats raw NGLs produced from gas processing plants located in Oklahoma, Kansas and the Texas panhandle. We own and operate, or ship through affiliated companies, approximately 4,600 miles of gathering and distribution lines with gathering capacity of 277 MBbls/d and distribution capacity of 360 MBbls/d. Our gathering lines are connected to approximately 90 percent of the natural gas processing plants located in the mid-continent producing areas.

Most natural gas produced at the wellhead contains a mixture of NGL components such as ethane, propane, butane and natural gasoline. Natural gas processing plants remove the NGLs from the natural gas stream to realize the higher economic value of the NGLs and to meet natural gas pipeline quality specifications, which limit NGL content in the natural gas stream.

The NGLs that are separated from the natural gas stream at the natural gas processing plants remain in a mixed, raw form until they are gathered, primarily by pipeline, and delivered to our fractionators. A fractionator, by applying heat and pressure, separates each NGL component into pure marketable products, such as ethane/propane mix, propane, iso-butane, normal butane and natural gasoline (collectively, NGL products). We have approximately 380 MBbls/d of fractionation capacity through our ownership or interest in four different facilities. These NGL products are then stored and/or distributed to petrochemical, heating and motor gasoline end users. Our fractionation and storage facilities are centrally located and provide flexible redelivery of NGL products to the two primary U.S. NGL market centers, Conway, Kansas and Mont Belvieu, Texas. We have the ability to satisfy our customer redelivery requests to these two market centers, and through our own account we can also market our NGL products to the highest value locations. We own or lease approximately 20.4 MMBbls of storage capacity in the mid-continent and gulf coast regions.

Our Natural Gas Liquids segment focuses on increasing market value of NGL products through use of our natural gas liquids assets. We are engaged in three primary business activities downstream of the natural gas gathering and processing segment.

•

Exchange Services – We provide gathering, fractionation, transportation, storage and treating of NGLs through term, fee-based exchange contracts. Under a typical fee-based exchange contract, we provide bundled services that include gathering and transporting raw NGLs to our fractionators, separating them into marketable products and redelivering the NGL products.

•

Optimization and Marketing – We use our asset base, portfolio of contracts and market knowledge to capture location price spreads through transactions that optimize the flow of our NGL products between the major U.S. market hubs in Conway, Kansas and Mont Belvieu, Texas. Optimization activities include redirecting NGL products to their highest value locations. In the mid-continent area, we purchase approximately two-thirds of our customers’ raw products on an index pricing basis, less an exchange fee. Additionally, we own and lease storage facilities in the mid-continent and gulf coast areas to capture seasonal price variances.

•

Isomerization – We own an isomerization unit in Conway, Kansas, with a capacity of 9 MBbls/d that converts normal butane to the more valuable iso-butane used by the refining industry to upgrade the octane of motor gasoline.

We are impacted by producer drilling activity, which is sensitive to geological success as well as availability of capital and commodity prices. The mid-continent region is currently experiencing a significant upturn in oil and gas drilling activity. This resurgence in drilling activity has been driven primarily by increased prices for natural gas and crude oil and by long-term projections of continued demand in the U.S. natural gas market. We continue to see production declines in certain fields that supply the gathering and processing facilities in our operating region and the possibility exists that declines may surpass development from new drilling. The factors that typically affect our ability to compete for NGL supplies are:

•

location of natural gas processing plants relative to our gathering pipelines,

•

location of our gathering pipelines relative to our competitors,

•

location of our fractionation facilities relative to our competitors,

•

efficiency, reliability and costs of operations including fuel and power consumption,

•

available fractionation and pipeline capacity, and

•

delivery capabilities to move NGL products to their highest value locations.

The main factors that affect our margins are:

•

transportation and fractionation volumes and associated fees,

•

commodity and regional pricing differences,

•

fees charged for storage, and

•

fees for marketing services.

Acquisition - The following acquisition is discussed beginning on page 25.

•

On July 1, 2005, we acquired the NGL businesses owned by Koch.

(a) -

Data not meaningful as the acquisition of these assets was completed July 1, 2005.

Operating Results - The results of operations for 2004 shown above are related to the natural gas liquids marketing business that was previously included in our Gathering and Processing segment. The increases for both the three- and nine-month periods are primarily related to the natural gas liquids assets acquired from Koch in July 2005. The increases associated with the acquisition for both the three- and nine-month periods include:

•

an increase in net margin of $27.2 million,

•

an increase in operating costs of $11.2 million, and

•

an increase in depreciation, depletion and amortization of $5.0 million.

The remaining net margin increase for both the three- and nine-month periods is primarily related to increased storage margins of $1.1 million and $4.8 million, respectively, from restructured storage contracts. Additionally, net margin also increased $1.9 million for the nine-month period as a result of higher NGL prices, driven primarily by higher marketing fees from increased NGL prices.

Increased storage regulatory compliance costs resulted in an additional $2.0 million in operating costs for the nine-month period in 2005 compared with 2004.

Pipelines and Storage

Overview - Our Pipelines and Storage segment, formerly known as Transportation and Storage, operates our intrastate natural gas transmission pipelines, natural gas storage, regulated natural gas liquids gathering and distribution pipelines and nonprocessable natural gas gathering facilities. We also provide interstate transportation service under Section 311(a) of the Natural Gas Policy

Act. We own or reserve capacity in five storage facilities in Oklahoma, three in Kansas and three in Texas, with a combined working capacity of approximately 59.6 Bcf, of which 8.0 Bcf is temporarily idle. The natural gas liquids gathering and distribution pipelines are interstate pipelines regulated by FERC and transport raw NGLs and NGL products pursuant to filed tariffs.

We operate approximately 5,600 miles of natural gas gathering and intrastate transmission pipelines in Oklahoma, Kansas and Texas, where we are regulated by the OCC, Kansas Corporation Commission (KCC) and Texas Railroad Commission (RRC), respectively. We have a peak transportation capacity of 2.9 Bcf/d. The majority of our revenues are derived from services provided to affiliates. We primarily serve local distribution companies (LDCs), large industrial companies, irrigation, power generation facilities and marketing companies. We compete directly with other interstate and intrastate pipelines and storage facilities. Competition for transportation services continues to increase as the FERC and state regulatory bodies continue to encourage more competition in the natural gas markets. Factors that affect competition are location, natural gas prices, fees for services and quality of service provided.

Following our acquisition of the Koch natural gas liquids assets in July 2005, we operate approximately 2,500 miles of regulated natural gas liquids gathering and distribution pipelines in Oklahoma, Kansas and Texas. Our natural gas liquids gathering system delivers raw NGLs gathered from gas processing plants located in these states to fractionation facilities in Medford, Oklahoma. Our NGL distribution pipelines move products from fractionators in Oklahoma and Kansas to market points in Conway, Kansas and Mont Belvieu, Texas. These pipelines are operated under the guidance and oversight of various governmental agencies including programs mandated by the OCC, the KCC, FERC, and other various state and governmental agencies. All of these NGL gathering and distribution pipelines are subject to tariff.

Our Pipeline and Storage segment is affected by the economy, natural gas price volatility and weather. The strength of the economy has a direct relationship on manufacturing and industrial companies and their resulting demand for natural gas and NGL components. Volatility in the natural gas market also impacts our customers’ decisions relating to injection and withdrawal of natural gas in storage. In addition, our NGL gathering pipelines are affected by operational or market driven changes in the output of the processing plants to which we are connected. Processing plant output may increase or decrease as a result of the relative value of natural gas to NGL prices. In addition, volume delivered through the system may increase or decrease as a result of the relative NGL price between the mid-continent and gulf coast regions. Natural gas transportation throughput fluctuates due to rainfall that impacts irrigation demand, hot temperatures that affect power generation demand and cold temperatures that affect heating demand.

Acquisition - The following acquisition is discussed beginning on page 25.

•

On July 1, 2005, the Pipelines and Storage segment acquired the FERC regulated assets that were part of our acquisition of the NGL businesses owned by Koch.

Operating results - Net margin increased for both the three and nine months ended September 30, 2005, compared with the same periods in 2004, primarily due to:

•

an increase of $13.9 million for both the three- and nine-month periods related to revenues on NGL gathering and distribution pipelines acquired in July 2005,

•

an increase of $6.9 million and $9.0 million, respectively, in transport revenues resulting from increased throughput due to favorable weather conditions for transportation and our improved fuel position and higher commodity prices, and

•

an increase of $2.6 million and $4.4 million, respectively, related to increased revenues from renegotiated contracts and increased storage activity as a result of a better pricing environment for inter- and intra-month business, improved fuel position and higher commodity prices.

Operating costs increased $7.2 million and $7.0 million for the three- and nine-month periods ended, respectively, compared with 2004, primarily related to $5.4 million for operating the newly-acquired NGL pipelines with the balance being driven by higher regulatory compliance costs and employee costs.

The increase in depreciation, depletion and amortization of approximately $3.0 million for both the three- and nine-month periods is primarily related to the newly-acquired NGL pipelines.

The decrease in other income (expense), net, for the nine-month period is due to the $6.9 million gain on the 2004 sale of certain assets, which was partially offset by unrelated litigation costs.

Energy Services

Overview - Our Energy Services segment’s primary focus is to create value for our customers by delivering physical products and risk management services through our network of contracted gas supply, transportation and storage capacity. These services include meeting our customers’ baseload, swing and peaking natural gas commodity requirements on a year-round basis. To provide these bundled services, we lease storage and transportation capacity. Our total storage capacity under lease is 86 Bcf, with maximum withdrawal capability of 2.3 Bcf per day and maximum injection capability of 1.6 Bcf per day. Our current transportation capacity is 1.6 Bcf per day. The contracted storage and transportation capacity connects the major supply and demand centers throughout the United States. With these contracted assets, our ongoing business strategies include identifying, developing and delivering specialized services and products for premium value to our customers, which are primarily LDCs, electric utilities, and commercial and industrial end users. Also, our storage and transportation capacity allows us opportunities to optimize these positions through our application of market knowledge and risk management skills. We provide risk management services to our customers.

Selected Financial and Operating Information - The following tables set forth certain selected financial and operating information for the Energy Services segment for the periods indicated. In the third quarter of 2005, we made the decision to sell our Spring Creek power plant and exit the power generation business. These assets were held for sale at September 30, 2005, and, accordingly, this component of our business is accounted for as discontinued operations, in accordance with Statement 144. In October 2005, we concluded that our Spring Creek power plant located in southwest Oklahoma had been impaired and recorded an impairment expense of $52.2 million. For additional information see discussion of discontinued operations on page 25.

Operating Results - Increases in natural gas price and volatility during the third quarter of 2005 had a direct impact on our Energy Services segment identified in the explanations below.

Energy and power revenues, as well as cost of sales and fuel, increased for the three-month period due to a 14.4 percent increase in sales volumes and a significant increase in commodity prices compared to the same period in 2004.

Net margin increased for the three months ended September 30, 2005, compared with the same period in 2004, primarily due to:

•

a net increase of $54.6 million related to higher margins from selling natural gas from storage and gains associated with an increase in basis spreads,

•

an increase of $5.3 million in power margins related to improved Electric Reliability Council of Texas (ERCOT) market heat-rates attributable to a 14.8 percent increase in cooling degree days compared to normal and an 18.7 percent increase in cooling days compared to the same period in 2004, and

•

a decrease of $10.3 million in financial trading margins.

Net margins increased for the nine month period primarily due to:

•

an increase of $29.6 million primarily related to storage sales in the third quarter that more than offset lower sales from storage during the first quarter,

•

an increase of $4.9 million in power margins related to improved ERCOT market heat-rates,

•

an increase of $6.6 million in margins related to optimizing transportation agreements associated with wider basis differentials,

•

a decrease of $9.0 million in margins from natural gas options trading, compared with the same period in 2004, and

•

a decrease of $2.3 million in retail activities related to reduced physical margins in the second quarter of 2005.

Net margin also increased $5.9 million for the nine-month period due to a timing difference in revenue recognition between physical transportation activities and the associated derivative contracts that hedge the physical transportation commitment. The derivative contracts hedging the transportation commitment were marked-to-market, as a portion of the derivatives did not highly correlate between the receipt and delivery points causing the derivative instrument to be marked-to-market without the physical underlying offset, or a portion of the hedged item was determined to be ineffective.

Operating costs increased $5.6 million and $3.7 million for the three- and nine-month periods, respectively, primarily due to increased employee-related costs and increased litigation expense.

Natural gas volumes marketed increased for the three- and nine-month periods due to our expanded Canadian operations, additional long-term contracts and opportunities to sell into supply-constrained markets.

Our natural gas in storage at September 30, 2005, was 63.9 Bcf compared to 79.1 Bcf at September 30, 2004. At September 30, 2005, our total natural gas storage capacity under lease was 86 Bcf compared to 85 Bcf at September 30, 2004.

At the beginning of the third quarter of 2004, we completed a reorganization of our Energy Services segment and renewed our focus on our physical marketing and storage business. Prior to the third quarter, we managed the Energy Services segment on an integrated basis and presented all energy trading activity on a net basis.

Concurrent with this reorganization, we evaluated the accounting treatment related to the presentation of revenues from the different types of activities to determine which amounts should be reported on a gross or net basis under the guidance in EITF Issue No. 03-11, “Reporting Realized Gains and Losses on Derivative Instruments That Are Subject to FASB Statement No. 133 and Not ‘Held for Trading Purposes’ as Defined in EITF Issue No. 02-3” (EITF 03-11). For derivative instruments considered held for trading purposes that result in physical delivery, the indicators in EITF Issue No. 02-3, “Issues Involved in Accounting for Derivative Contracts Held for Trading Purposes and Contracts Involved in Energy Trading and Risk Management Activities” were used to determine the proper treatment. These activities and all financially settled derivative contracts will continue to be reported on a net basis.

For derivative instruments that are not considered “held for trading purposes” and result in physical delivery, the indicators in EITF 03-11 and EITF Issue No. 99-19, “Reporting Revenue Gross as a Principal versus Net as an Agent” (EITF 99-19) were used to determine the proper treatment. We began accounting for the realized revenues and purchase costs of these contracts that result in physical delivery on a gross basis beginning with the third quarter of 2004. We apply the indicators in EITF 99-19 to determine the appropriate accounting treatment for non-derivative contracts that result in physical delivery. Derivatives that qualify for the normal purchase or sale exception as defined in Statement 133 are also reported on a gross basis. Prior periods have not been adjusted for this change; therefore, comparisons to prior periods may not be meaningful. Reporting of these transactions on a gross basis did not impact operating income, but resulted in an increase to revenues and cost of sales and fuel.

Marketing and storage activities primarily include physical marketing (purchases and sales) using our firm storage and transportation capacity, including cash flow and fair value hedges and other derivative instruments to manage our risk associated with these activities. The combination of owning supply, controlling strategic assets and risk management services allows us to provide commodity-diverse products and services to our customers such as peaking and load following services. Power activities are also included in the marketing and storage business. Retail marketing includes revenues from providing physical marketing and supply services to residential and small commercial and industrial customers. Financial trading revenues include activities that are generally executed using financially settled derivatives. These activities are normally short-term in nature with a focus of capturing short-term price volatility. The following table shows margins from these activities.

Distribution

Overview - Our Distribution segment provides natural gas distribution services to over 2 million customers in Oklahoma, Kansas and Texas through Oklahoma Natural Gas, Kansas Gas Service and Texas Gas Service, respectively. We serve residential, commercial, industrial and transportation customers in all three states. In Oklahoma and Kansas, we also serve wholesale customers and in Texas, we also serve public authority customers. We provide gas service to approximately 86 percent, 71 percent and 14 percent of the distribution markets of Oklahoma, Kansas and Texas, respectively. Oklahoma Natural Gas and Kansas Gas Service are subject to regulatory oversight by the OCC and KCC, respectively. Texas Gas Service is subject to regulatory oversight by the various municipalities that it serves, which have primary jurisdiction in their respective areas. Texas

Gas Service’s rates in areas adjacent to the various municipalities and appellate matters are subject to regulatory oversight by the RRC. This segment also includes an interstate gas transportation company, OkTex Pipeline, which is regulated by the FERC.

Our operating results are primarily impacted by the number of customers, usage and the ability to establish delivery rates that provide an authorized rate of return on our investment and cost of service. Gas costs are passed through to our customers based on the actual cost of gas purchased by the respective distribution division. Changes in the level of gas sales can occur from year to year without significantly impacting our gross margin, since most factors that affect gas sales also affect cost of gas by an equivalent amount. Gas sales to residential and commercial customers are seasonal, as a substantial portion of gas is used principally for heating. Accordingly, the volume of gas sales is consistently higher during the heating season (November through March) than in other months of the year.

In September 2005, Hurricane Rita caused significant damage to customers’ homes and businesses in the Texas Gas Service service area located in south Jefferson County and Port Arthur, Texas. Texas Gas Service suffered damage to its Port Arthur service center, meters in south Jefferson County and Port Arthur, Texas, and incurred system gas loss. The financial impact will be nominal due to insurance coverage that covers property damage, gas loss and business interruption loss.
