NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

A. SUMMARY OF ACCOUNTING POLICIES

Our accompanying unaudited consolidated financial statements have been prepared in accordance with GAAP 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. The 2008 year-end consolidated balance sheet data was derived from audited financial statements but does not include all disclosures required by GAAP. These unaudited consolidated financial statements should be read in conjunction with our audited consolidated financial statements in our Annual Report.

Our accounting policies are consistent with those disclosed in Note A of the Notes to Consolidated Financial Statements in our Annual Report. The following recently issued accounting pronouncements will affect our consolidated financial statements during 2009.

Noncontrolling Interests - Statement 160, “Noncontrolling Interests in Consolidated Financial Statements - an amendment of ARB No. 51,” requires noncontrolling interests (previously referred to as minority interests) to be reported as a component of equity. Statement 160 was effective for our year beginning January 1, 2009, and required retroactive adoption of the presentation and disclosure requirements for existing noncontrolling interests.

Derivative Instruments and Hedging Activities - Statement 161, “Disclosures about Derivative Instruments and Hedging Activities - an amendment to FASB Statement No. 133,” requires enhanced disclosures about how derivative and hedging activities affect our financial position, financial performance and cash flows. Statement 161 was effective for our year beginning January 1, 2009, and has been applied prospectively. See Note C for disclosures of our derivative instruments and hedging activities.

Fair Value Measurements - As of January 1, 2009, we have applied the provisions of Statement 157, “Fair Value Measurements,” to assets and liabilities that are measured at fair value on a nonrecurring basis subsequent to initial recognition, and the impact was not material. See Note B for disclosures of our fair value measurements.

Limited Partners’ Net Income Per Unit - EITF 07-4, “Application of the Two-Class Method under FASB Statement No. 128 to Master Limited Partnerships,” was effective for our year beginning January 1, 2009, and required retroactive application. Application of EITF 07-4 had no impact on our limited partners’ net income per unit for the three and six months ended June 30, 2009 and 2008. See Note L for a discussion of our calculation of basic and diluted limited partners’ net income per unit.

Interim Disclosures about Fair Value - FSP 107-1 and Accounting Principles Board (APB) Opinion No. 28-1, “Interim Disclosures about Fair Value of Financial Instruments,” require disclosures of fair value of financial instruments for interim reporting periods, which were effective for our quarter ended June 30, 2009. These disclosures are included in Note B.

Subsequent Events - Statement 165, “Subsequent Events,” establishes standards of accounting for and disclosures of events that occur after the balance sheet date but before consolidated financial statements are issued. We have evaluated subsequent events through August 6, 2009, the date our consolidated financial statements were issued, and all required disclosures have been made.

FASB Accounting Standards Codification - Statement 168, “The FASB Accounting Standards Codification and the Hierarchy of Generally Accepted Accounting Principles,” establishes the FASB Accounting Standards Codification as the source of authoritative accounting principles recognized by the FASB to be applied by nongovernmental entities in the preparation of financial statements in conformity with GAAP. Statement 168 will change the manner in which we reference authoritative accounting principles in our consolidated financial statements and will be effective for our September 30, 2009, Quarterly Report.

B. FAIR VALUE MEASUREMENTS

Refer to Notes A and C of the Notes to Consolidated Financial Statements in our Annual Report for a discussion of our fair value measurements and the fair value hierarchy.

Recurring Fair Value Measurements - The following tables set forth our recurring fair value measurements for the periods indicated.

	June 30, 2009
	Level 1		Level 2			Level 3			Netting (a)			Total
	(Thousands of dollars)
Derivatives
Assets (b)	$	-	$	10,550		$	15,062		$	(6,880	)	$	18,732
Liabilities (c)	$	-	$	(4,796	)	$	(3,465	)	$	6,880		$	(1,381	)
(a) - Our derivative assets and liabilities are presented in our Consolidated Balance Sheet on a net basis. We net derivative assets and liabilities when a legally enforceable master netting arrangement exists between us and the counterparty to a derivative contract.
(b) - Included in derivative financial instruments in our Consolidated Balance Sheet.
(c) - Included in deferred credits and other liabilities in our Consolidated Balance Sheet.

	December 31, 2008
	Level 1		Level 2			Level 3			Netting (a)			Total
	(Thousands of dollars)
Derivatives
Assets (b)	$	-	$	26,131		$	37,649		$	-		$	63,780
(a) - Our derivative assets and liabilities are presented in our Consolidated Balance Sheet on a net basis. We net derivative assets and liabilities when a legally enforceable master netting arrangement exists between us and the counterparty to a derivative contract.
(b) - Included in derivative financial instruments in our Consolidated Balance Sheet.

At June 30, 2009, and December 31, 2008, we had no cash collateral held or posted under our master netting arrangements.

In accordance with Statement 157, we categorize derivatives for which fair value is determined based on multiple inputs within a single level, based on the lowest level input that is significant to the fair value measurement in its entirety.

Our derivative instruments categorized as Level 2 include non-exchange traded fixed-price swaps for natural gas and crude oil that are valued based on NYMEX-settled prices. Our derivative instruments categorized as Level 3 include over-the-counter fixed-price swaps for purity NGL products and natural gas basis swaps. These swaps are valued based on information from a pricing service, the forward NYMEX curve for crude oil, correlations of specific NGL purity products to crude oil and internally developed basis curves incorporating observable and unobservable market data. We corroborate the data on which our fair value estimates are based using our market knowledge of recent transactions and day-to-day pricing fluctuations and analysis of historical relationships of data from the pricing service compared with actual settlements and correlations. We do not believe that our Level 3 fair value estimates have a material impact on our results of operations, as the majority of our derivatives are accounted for as cash flow hedges for which ineffectiveness is not material.

There were no material gains (losses) for the three and six months ended June 30, 2009 and 2008, included in earnings attributable to the change in unrealized gains (losses) relating to assets and liabilities classified as Level 3 fair value measurements still held as of the end of the period.

Other Financial Instruments - The approximate fair value of cash and cash equivalents, accounts receivable and accounts payable is equal to book value, due to their short-term nature. The fair value of borrowings under our $1.0 billion amended and restated revolving credit agreement dated March 30, 2007 (Partnership Credit Agreement), approximates the carrying value since the interest rates are periodically adjusted to reflect current market conditions. The estimated fair value of the aggregate of our senior notes outstanding, including current maturities, approximates the book value of approximately $3.1 billion at June 30, 2009, based on quoted market prices for similar issues with similar terms and maturities.

C. RISK MANAGEMENT AND HEDGING ACTIVITIES USING DERIVATIVES

Risk Management Activities - We are sensitive to changes in natural gas, condensate and NGL prices, principally as a result of contractual terms under which these commodities are processed, purchased and sold. We use physical forward sales and financial derivatives to secure a certain price for a portion of our natural gas, condensate and NGL products. We follow established policies and procedures to assess risk and approve, monitor and report our risk management activities. We have not used these instruments for trading purposes. We are also subject to the risk of interest rate fluctuation in the normal course of business.

Commodity price risk - Commodity price risk refers to the risk of loss in cash flows and future earnings arising from adverse changes in the price of natural gas, NGLs and condensate. We use the following commodity derivative instruments to mitigate the commodity price risk associated with a portion of the forecasted sales of these commodities.

·	Futures contracts - Standardized exchange-traded contracts to purchase or sell natural gas and crude oil at a specified price, requiring delivery on or settlement through the sale or purchase of an offsetting contract by a specified future date under the provisions of exchange regulations.

·	Forward contracts - Commitments to purchase or sell natural gas, crude oil or NGLs for delivery at some specified time in the future. Forward contracts are different from futures in that forwards are customized and non-exchange traded.

Swaps - Financial trades involving the exchange of payments based on two different pricing structures for a commodity. In a typical commodity swap, parties exchange payments based on changes in the price of a commodity or a market index, while fixing the price they effectively pay or receive for the physical commodity. As a result, one party assumes the risks and benefits of the movements in market prices while the other party assumes the risks and benefits of a fixed price for the commodity.

In our Natural Gas Gathering and Processing segment, we are exposed to commodity price risk, primarily NGLs and natural gas, as a result of receiving commodities in exchange for services associated with our POP contracts. To a lesser extent, exposures arise from the relative price differential between NGLs and natural gas, or the gross processing spread, with respect to our keep-whole processing contracts. We are also exposed to basis risk between the various production and market locations where we buy and sell commodities. As part of our hedging strategy, we use the aforementioned commodity derivative instruments to minimize earnings volatility related to natural gas, NGL and condensate price fluctuations. We reduce our gross processing spread exposure through a combination of physical and financial hedges. We utilize a portion of our POP equity natural gas as an offset, or natural hedge, to an equivalent portion of our keep-whole shrink requirements. This has the effect of converting our gross processing spread risk to NGL commodity price risk. We hedge a portion of the forecasted sales of the commodities we retain, including NGLs, natural gas and condensate.

In our Natural Gas Liquids Gathering and Fractionation segment, we are exposed to basis risk primarily as a result of the relative value of NGL purchases at one location and sales at another location. To a lesser extent, we are exposed to commodity price risk resulting from the relative values of the various NGL products to each other, NGLs in storage and the relative value of NGLs to natural gas. We utilize fixed-price physical forward contracts to reduce earnings volatility related to NGL price fluctuations. At June 30, 2009, we were not using any financial derivative instruments with respect to our NGL gathering and fractionation activities.

In our Natural Gas Pipelines segment, we are exposed to commodity price risk because our intrastate and interstate natural gas pipelines collect natural gas from our customers for operations or as part of our fee for services provided. When the amount of natural gas consumed in operations by these pipelines differs from the amount provided by our customers, our pipelines must buy or sell natural gas, or store or use natural gas from inventory, which can expose us to commodity price risk depending on the regulatory treatment for this activity. We use physical forward sales to reduce earnings volatility related to natural gas price fluctuations. At June 30, 2009, we were not using any financial derivative instruments with respect to our intrastate and interstate pipeline operations.

Table of Contents

Interest rate risk - We manage interest rate risk through the use of fixed-rate debt, floating-rate debt and, at times, interest-rate swaps. Interest-rate swaps are agreements to exchange an interest payment at some future point based on the differential between two interest rates. Floating-rate swaps may be used to convert the fixed rates of long-term borrowings into short-term variable rates.

Accounting Treatment - We account for derivative instruments and hedging activities in accordance with Statement 133, “Accounting for Derivative Instruments and Hedging Activities,” as amended. Under Statement 133, entities are required to record derivative instruments at fair value, with the exception of normal purchases and normal sales that are expected to result in physical delivery. 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 cash flow hedging relationship and, if so, the reason for holding it.

The table below summarizes the various ways in which we account for our derivative instruments and the impact on our consolidated financial statements.

	Recognition and Measurement
Accounting Treatment	Balance Sheet	Income Statement
Normal purchases and normal sales	- Fair value not recorded	- Change in fair value not recognized in earnings
Mark-to-market	- Recorded at fair value	- Change in fair value recognized in earnings
Cash flow hedge	- Recorded at fair value	- Ineffective portion of the gain or loss on the derivative instrument is recognized in earnings
	- Effective portion of the gain or loss on the derivative instrument is reported initially as a component of accumulated other comprehensive income (loss)	- Effective portion of the gain or loss on the derivative instrument is reclassified out of accumulated other comprehensive income (loss) into earnings when the forecasted transaction affects earnings
Fair value hedge	- Recorded at fair value	- The gain or loss on the derivative instrument is recognized in earnings
	- Change in fair value of the hedged item is recorded as an adjustment to its book value	- Change in fair value of the hedged item is recognized 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 forecasted transaction that has been designated as the hedged item with a cash flow hedge. We assess the effectiveness of hedging relationships quarterly by performing a regression analysis on our fair value and cash flow hedging relationships to determine whether the hedge relationships are highly effective on a retrospective and prospective basis. We also document our normal purchases and normal sales transactions that we expect to result in physical delivery and that we elect to exempt from derivative accounting treatment.

Cash flows from futures, forwards and swaps that are accounted for as hedges are included in the same cash flow statement category as the cash flows from the related hedged items.

Fair Values of Derivative Instruments - Statement 157 defines fair value as the price that would be received to sell an asset or transfer a liability in an orderly transaction between market participants at the measurement date. See Note B for a discussion of the inputs associated with our fair value measurements and our fair value hierarchy disclosures.

As of June 30, 2009, we had $25.6 million of derivative assets and $8.3 million of derivative liabilities, excluding the impact of netting, all of which related to commodity contracts.

As of June 30, 2009, we had fixed-price natural gas swaps with a notional quantity of 4.5 Bcf and natural gas basis swaps with a notional quantity of 4.5 Bcf. Additionally, we had fixed-price crude oil and NGL swaps with a notional quantity of 2.0 MMBbl.

Cash Flow Hedges - At June 30, 2009, our Consolidated Balance Sheet reflected an unrealized gain of $20.5 million in accumulated other comprehensive income (loss), with a corresponding offset in derivative financial instrument assets and liabilities that will be realized within the next 18 months as the forecasted transactions affect earnings. If prices remain at

current levels, we will recognize $21.8 million in gains over the next 12 months, and we will recognize losses of $1.3 million thereafter.

The following table sets forth the effect of cash flow hedges recognized in other comprehensive income (loss) for the periods indicated.

Derivatives in Cash Flow Hedging Relationships	Three Months Ended June 30, 2009			Six Months Ended June 30, 2009

Interest rate contracts	Interest expense		436		872
Total gain (loss) reclassified from accumulated other comprehensive income (loss) into net income (effective portion)		$	16,419	$	35,620

Ineffectiveness related to our cash flow hedges was not material for the three and six months ended June 30, 2009 and 2008. In the event that it becomes probable that a forecasted transaction will not occur, we would discontinue cash flow hedge treatment, which would affect earnings. There were no gains or losses due to the discontinuance of cash flow hedge treatment during the three and six months ended June 30, 2009 and 2008.

Fair Value Hedges - In prior years, we terminated various interest-rate swap agreements. The net savings from the termination of these swaps is being recognized in interest expense over the terms of the debt instruments originally hedged. Interest expense savings for the six months ended June 30, 2009, from amortization of terminated swaps was $1.9 million, and the remaining amortization of terminated swaps will be recognized over the following periods.


	(Millions of dollars)
Remainder of 2009		$	1.8
2010		$	3.7
2011		$	0.9

At June 30, 2009, none of the interest on our fixed-rate debt was swapped to floating using interest-rate swaps.

Credit Risk - All the commodity derivative contracts we enter into are with ONEOK Energy Services Company, L.P. (OES), a subsidiary of ONEOK. OES enters into similar commodity derivative contracts with third parties at our direction and on our behalf. We have an indemnification agreement with OES that indemnifies and holds OES harmless from any liability they may incur solely as a result of entering into commodity derivative contracts on our behalf. Derivative assets for which we would indemnify OES in the event of a default by the counterparty total $18.7 million at June 30, 2009, and are with investment grade counterparties that are primarily in the oil and gas sector.

E. PARTNERS’ EQUITY

Equity Issuance - In June 2009, we completed an underwritten public offering of 5,000,000 common units at $45.81 per common unit, generating net proceeds of approximately $219.9 million after deducting underwriting discounts but before offering expenses. In conjunction with the public offering of common units, ONEOK Partners GP contributed $4.7 million in order to maintain its 2 percent general partner interest in us.

In July 2009, we sold an additional 486,690 common units at $45.81 per common unit to the underwriters of the public offering upon the partial exercise of their option to purchase additional common units to cover over-allotments. We received net proceeds of approximately $21.4 million from the sale of the common units after deducting underwriting discounts but before offering expenses. In conjunction with the partial exercise by the underwriters, ONEOK Partners GP contributed $0.5 million in order to maintain its 2 percent general partner interest in us.

As a result of these transactions, ONEOK and its subsidiaries now hold an aggregate 45.1 percent interest in us.

We used the proceeds from the sale of common units and the general partner contributions to repay borrowings under our Partnership Credit Agreement and for general partnership purposes.

Cash Distributions - For the six months ended June 30, 2009, cash distributions included $45.5 million paid to our general partner, of which $40.6 million was related to incentive distributions. These distributions pertained to the fourth quarter of 2008 and first quarter of 2009. In July 2009, we declared a cash distribution of $1.08 per unit ($4.32 per unit on an annualized basis) for the second quarter of 2009. The distribution will be paid on August 14, 2009, to unitholders of record as of July 31, 2009.

For the six months ended June 30, 2008, cash distributions included $35.3 million paid to our general partner, of which $30.9 million was related to incentive distributions. These distributions pertained to the fourth quarter of 2007 and first quarter of 2008.

F. CREDIT FACILITIES

Our Partnership Credit Agreement, which expires in March 2012, contains certain financial and other typical covenants as discussed in Note H of the Notes to Consolidated Financial Statements in our Annual Report. Among other things, these covenants include maintaining a ratio of indebtedness to adjusted EBITDA (EBITDA, as adjusted for all non-cash charges and increased for projected EBITDA from certain lender-approved capital expansion projects) of no more than 5 to 1. At June 30, 2009, our ratio of indebtedness to adjusted EBITDA was 4.3 to 1, and we were in compliance with all covenants under our Partnership Credit Agreement.

- 16 -

Table of Contents

At June 30, 2009, we had $360 million of borrowings outstanding and $586.5 million of credit available under our Partnership Credit Agreement. At June 30, 2009, we had a total of $49.2 million issued in letters of credit outside of the Partnership Credit Agreement.

Borrowings under our Partnership Credit Agreement are short term in nature, ranging from one day to six months. Accordingly, these borrowings are classified as short-term notes payable.

G. LONG-TERM DEBT

Debt Issuance - In March 2009, we completed an underwritten public offering of $500 million aggregate principal amount of 8.625 percent Senior Notes due 2019 (2019 Notes). The 2019 Notes were issued under our existing shelf registration statement filed with the SEC.

We may redeem the 2019 Notes, in whole or in part, at any time prior to their maturity at a redemption price equal to the principal amount, plus accrued and unpaid interest and a make-whole premium. The redemption price will never be less than 100 percent of the principal amount of the 2019 Notes plus accrued and unpaid interest to the redemption date. The 2019 Notes are senior unsecured obligations, ranking equally in right of payment with all of our existing and future unsecured senior indebtedness, and effectively junior to all of the existing and future debt and other liabilities of our non-guarantor subsidiaries. The 2019 Notes are nonrecourse to our general partner.

The net proceeds from the 2019 Notes, after deducting underwriting discounts and commissions and expenses, of approximately $494.3 million were used to repay indebtedness outstanding under our Partnership Credit Agreement.

The 2019 Notes are fully and unconditionally guaranteed on a senior unsecured basis by ONEOK Partners Intermediate Limited Partnership (Intermediate Partnership). The guarantee ranks equally in right of payment to all of the Intermediate Partnership’s existing and future unsecured senior indebtedness.

The terms of the 2019 Notes are governed by an indenture, dated as of September 25, 2006, between us and Wells Fargo Bank, N.A., as trustee, as supplemented by the Fifth Supplemental Indenture, dated March 3, 2009 (Indenture). The Indenture does not limit the aggregate principal amount of debt securities that may be issued and provides that debt securities may be issued from time to time in one or more additional series. The Indenture contains covenants including, among other provisions, limitations on our ability to place liens on our property or assets and to sell and leaseback our property.

The 2019 Notes will mature on March 1, 2019. We will pay interest on the 2019 Notes on March 1 and September 1 of each year. The first payment of interest on the 2019 Notes will be made on September 1, 2009. Interest on the 2019 Notes accrues from March 3, 2009, which was the issuance date.

H. COMMITMENTS AND CONTINGENCIES

Investment in Northern Border Pipeline - In March 2009, we made an equity contribution of $4.3 million to Northern Border Pipeline. Northern Border Pipeline anticipates requiring an additional equity contribution of approximately $76 million from its partners in the third quarter of 2009, of which our share will be approximately $38 million based on our 50 percent equity interest.

Environmental Liabilities - We are subject to multiple environmental, historical and wildlife preservation laws and regulations affecting many aspects of our present and future operations. Regulated activities include those involving air emissions, stormwater and wastewater discharges, handling and disposal of solid and hazardous wastes, hazardous materials transportation, and pipeline and facility construction. These laws and regulations require us to obtain and comply with a wide variety of environmental clearances, registrations, licenses, permits 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 our results of operations. If a leak or spill of hazardous substances or petroleum products occurs from lines or facilities that we own, operate or otherwise use, we could be held jointly and severally liable for all resulting liabilities, including response, investigation and clean-up costs, which could materially affect our results of operations and cash flows. 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 could have a material adverse effect on our business, financial condition and results of operations.

L. LIMITED PARTNERS’ NET INCOME PER UNIT

As discussed in Note A, we adopted EITF 07-4 on January 1, 2009, which requires us to utilize the two-class method of calculating net income per unit.

Limited partners’ net income per unit is computed by dividing net income attributable to ONEOK Partners, L.P., after deducting the general partner’s allocation, by the weighted-average number of outstanding limited partner units, which includes our common and Class B limited partner units. As discussed in Note B of the Notes to Consolidated Financial Statements in our Annual Report, ONEOK, as sole holder of our Class B units, has waived its right to receive increased quarterly distributions on the Class B units. Because ONEOK has waived its right to increased quarterly distributions, currently each Class B unit and common unit share equally in the earnings of the Partnership and neither has any liquidation or other preferences. ONEOK retains the option to withdraw its waiver at any time by giving us no less than 90 days advance notice. ONEOK Partners GP owns the entire 2 percent general partnership interest in us, which entitles it to incentive distribution rights that provide for an increasing proportion of cash distributions from the partnership as the distributions made to limited partners increase above specified levels.

For purposes of our calculation of limited partners’ net income per unit, net income attributable to ONEOK Partners, L.P. is generally allocated to the general partner as follows: (i) an amount based upon the 2 percent general partner interest in net income attributable to ONEOK Partners, L.P. and (ii) the amount of the general partner’s incentive distribution rights based on the total cash distributions declared for the period. The amount of incentive distribution allocated to our general partner totaled $21.4 million and $41.8 million for the three and six months ended June 30, 2009, respectively.

The terms of our Partnership Agreement limit the general partner’s incentive distribution to the amount of available cash calculated for the period. As such, incentive distribution rights are not allocated on undistributed earnings or distributions in excess of earnings. Gains resulting from interim capital transactions, as defined in our Partnership Agreement, are generally not subject to distribution; however, our Partnership Agreement provides that if such distributions were made, the incentive distribution rights would not apply. For additional information regarding our general partner’s incentive distribution rights, see “Cash Distribution Policy” under Part II, Item 5, Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities, in our Annual Report.

M. RELATED-PARTY TRANSACTIONS

Intersegment and affiliate sales are recorded on the same basis as sales to unaffiliated customers. Our Natural Gas Gathering and Processing segment sells natural gas to ONEOK and its subsidiaries. A portion of our Natural Gas Pipelines segment’s revenues are from ONEOK and its subsidiaries. Additionally, our Natural Gas Gathering and Processing segment and Natural Gas Liquids Gathering and Fractionation segment purchase a portion of the natural gas used in their operations from ONEOK and its subsidiaries.

We have certain contractual rights to the Bushton Plant. Our Processing and Services Agreement with ONEOK and OBPI sets out the terms by which OBPI provides services to us at the Bushton Plant through 2012. We have contracted for all of the capacity of the Bushton Plant from OBPI. In exchange, we pay OBPI for all costs and expenses of the Bushton Plant, including reimbursement of a portion of OBPI’s obligations under equipment leases covering the Bushton Plant.

Under the Services Agreement with ONEOK, ONEOK Partners GP and NBP Services (Services Agreement), our operations and the operations of ONEOK and its affiliates can combine or share certain common services in order to operate more efficiently and cost-effectively. Under the Services Agreement, ONEOK provides to us similar services that it provides to its affiliates, including those services required to be provided pursuant to our Partnership Agreement. ONEOK Partners GP operates our interstate natural gas pipeline assets according to each pipeline’s operating agreement. ONEOK Partners GP may purchase services from ONEOK and its affiliates pursuant to the terms of the Services Agreement. ONEOK Partners GP has no employees and utilizes the services of ONEOK and ONEOK Services Company to fulfill its operating obligations.

ONEOK and its affiliates provide a variety of services to us under the Services Agreement, including cash management and financial services, employee benefits provided through ONEOK’s benefit plans, administrative services, insurance and office space leased in ONEOK’s headquarters building and other field locations. Where costs are specifically incurred on behalf of one of our affiliates, the costs are billed directly to us by ONEOK. In other situations, the costs may be allocated to us through a variety of methods, depending upon the nature of the expense and activities. For example, a service that applies equally to all employees is allocated based upon the number of employees. However, an expense benefiting the consolidated company but having no direct basis for allocation is allocated by the modified Distrigas method, a method using a combination of ratios that includes gross plant and investment, earnings before interest and taxes and payroll expense. It is not practicable to determine what these general overhead costs would be on a stand-alone basis. All costs directly charged or allocated to us are included in our Consolidated Statements of Income.

Our derivative contracts with OES are discussed under “Credit Risk” in Note C.

ITEM 2.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis should be read in conjunction with our unaudited consolidated financial statements and the Notes to Consolidated Financial Statements in this Quarterly Report, as well as our Annual Report.

EXECUTIVE SUMMARY

The following discussion highlights some of our achievements and significant issues affecting us for the periods presented. Please refer to the “Capital Projects,” “Financial Results and Operating Information,” and “Liquidity and Capital Resources” sections of Management’s Discussion and Analysis of Financial Condition and Results of Operations and our consolidated financial statements for additional information.

Outlook - We expect challenging economic conditions to persist for the remainder of 2009 and into 2010, compared with 2008, when we experienced unprecedented drilling activity, supply growth and commodity price levels for natural gas, NGLs and crude oil. We anticipate that lower commodity prices will continue to result in reduced drilling activity, and current economic conditions will result in reduced demand for NGL products from the petrochemical industry. Although we have been able to access the capital markets for our debt and equity needs in 2009, we expect continued volatility and possible disruption in the financial markets, which could limit our access to those markets or increase the cost of issuing new securities in the future. We expect that depressed commodity prices and tighter capital markets will result in the sale or consolidation of underperforming assets in the industry, which may present opportunities for us.

Operating Results - Limited partners’ net income per unit decreased to $0.81 for the three months ended June 30, 2009, compared with $1.46 for the same period in 2008. For the six-month period, limited partners’ net income per unit decreased to $1.66 from $2.94 for the same period last year. The decrease in limited partners’ net income per unit for the three- and six-month periods is primarily due to the following:

·	a decrease in net margin primarily due to:

-	significantly lower realized commodity prices in our Natural Gas Gathering and Processing segment;

-	narrower NGL product price differentials in our Natural Gas Liquids Gathering and Fractionation segment; and

-	the impact of lower natural gas prices on retained fuel in our Natural Gas Pipelines segment;

partially offset by

-	increased NGL throughput primarily associated with the completion of the Overland Pass Pipeline and related expansion projects, as well as new supply connections in our Natural Gas Liquids Gathering and Fractionation segment and Natural Gas Liquids Pipelines segment;

-	incremental natural gas transportation margins from the Guardian Pipeline expansion and extension that was completed in February 2009 in our Natural Gas Pipelines segment; and

-	higher volumes processed and sold for the six months ended June 30, 2009, in our Natural Gas Gathering and Processing segment.

an increase in operating costs at our fractionation facilities, which included incremental operating expenses associated with the recently expanded Bushton Plant that resumed operations in the third quarter of 2008, and due to the operations of Overland Pass Pipeline that began in the fourth quarter of 2008;

·	an increase in depreciation expense associated with our completed capital projects; and

·	an increase in interest expense primarily due to increased borrowings to fund our capital projects.

As a result of these transactions, ONEOK and its subsidiaries now hold an aggregate 45.1 percent interest in us.

Table of Contents

We used the proceeds from the sale of common units and the general partner contributions to repay borrowings under our Partnership Credit Agreement and for general partnership purposes.

Debt Issuance - In March 2009, we completed an underwritten public offering of $500 million aggregate principal amount of 8.625 percent Senior Notes due 2019. We used the proceeds from the offering to repay indebtedness outstanding under our Partnership Credit Agreement.

Cash Distributions - In July 2009, we declared a cash distribution of $1.08 per unit ($4.32 per unit on an annualized basis), an increase of approximately 2 percent over the $1.06 per unit declared in July 2008.

Capital Projects - The following projects were placed in service during the first six months of 2009:

·	Guardian Pipeline’s expansion and extension project;

·	D-J Basin lateral pipeline; and

·	Williston Basin gas processing plant expansion.

Capital expenditures in 2009 are expected to be significantly lower than in 2008, when we spent approximately $1.3 billion. We plan to spend approximately $570 million on capital expenditures in 2009, of which approximately $509 million is for growth projects.

CAPITAL PROJECTS

Overland Pass Pipeline - In November 2008, Overland Pass Pipeline Company completed construction of a 760-mile natural gas liquids pipeline from Opal, Wyoming, to the Mid-Continent natural gas liquids market center in Conway, Kansas. The Overland Pass Pipeline is designed to transport approximately 110 MBbl/d of unfractionated NGLs and can be increased to approximately 255 MBbl/d with additional pump facilities. At the end of the second quarter 2009, approximately 85 MBbl/d were flowing on Overland Pass Pipeline. Overland Pass Pipeline Company is a joint venture between us and a subsidiary of The Williams Companies, Inc. (Williams). We own 99 percent of the joint venture and are currently operating the pipeline. On or before November 17, 2010, Williams has the option to increase its ownership in Overland Pass Pipeline Company, which includes the Piceance Lateral and D-J Basin Lateral pipeline projects, up to 50 percent, with the purchase price being determined in accordance with the joint venture’s operating agreement. If Williams exercises its option to increase its ownership to the full 50 percent, Williams would have the option to become operator. If Williams does not elect to increase its ownership to at least 10 percent, we will have the right, but not the obligation, to purchase Williams’ entire ownership interest, with the purchase price being determined in accordance with the joint venture’s operating agreement. The pipeline project cost approximately $575 million, excluding AFUDC.

As part of a long-term agreement, Williams dedicated its NGL production from two of its natural gas processing plants in Wyoming, estimated to be approximately 70 MBbl/d, to the Overland Pass Pipeline. We provide downstream fractionation, storage and transportation services to Williams. We have also reached agreements with certain producers for supply commitments from the D-J Basin and Piceance Lateral pipelines for up to an additional 80 MBbl/d, and we are negotiating agreements with other producers for supply commitments that could add an additional 60 MBbl/d of supply to this pipeline within the next three to five years.

We also invested approximately $239 million, excluding AFUDC, to expand our existing fractionation and storage capabilities and to increase the capacity of our natural gas liquids distribution pipelines. Part of this expansion included adding new fractionation facilities at our Bushton, Kansas location, which increased the total fractionation capacity at the Bushton facility to 150 MBbl/d from 80 MBbl/d. The addition of the new facilities and the upgrade to the existing fractionator were completed in October 2008. Additionally, portions of our natural gas liquids distribution pipeline upgrades were completed in the second and third quarters of 2008. Overland Pass Pipeline Company is included in our Natural Gas Liquids Pipelines segment, while the associated expansions are included in our Natural Gas Liquids Gathering and Fractionation segment and Natural Gas Liquids Pipelines segment.

Piceance Lateral Pipeline - In October 2008, Overland Pass Pipeline Company began construction of a 150-mile lateral pipeline with capacity to transport as much as 100 MBbl/d of unfractionated NGLs from the Piceance Basin in Colorado to the Overland Pass Pipeline. Williams will dedicate its NGL production from an existing natural gas processing plant and a new natural gas processing plant, with estimated volumes totaling approximately 30 MBbl/d, to be transported by the lateral pipeline. We continue to negotiate with other producers for supply commitments. Construction is expected to be completed during the third quarter of 2009. The project is currently estimated to cost in the range of $110 million to $140 million, excluding AFUDC. This project is in our Natural Gas Liquids Pipelines segment.

D-J Basin Lateral Pipeline - In March 2009, Overland Pass Pipeline Company placed in service the 125-mile natural gas liquids lateral pipeline from the Denver-Julesburg Basin in northeastern Colorado to the Overland Pass Pipeline. The pipeline has capacity to transport as much as 55 MBbl/d of unfractionated NGLs. The project cost was approximately $70 million, excluding AFUDC. Volumes are expected to exceed 31 MBbl/d during the third quarter of 2009, with the potential for an additional 10 MBbl/d from new drilling and plant upgrades in the next two years. This project is in our Natural Gas Liquids Pipelines segment.

Arbuckle Natural Gas Liquids Pipeline - In July 2009, we completed construction of the 440-mile Arbuckle pipeline project, a natural gas liquids pipeline system that delivers unfractionated NGLs from points in southern Oklahoma and Texas to the Texas Gulf Coast. The Arbuckle pipeline system has the capacity to transport 160 MBbl/d of unfractionated NGLs, expandable to 210 MBbl/d with additional pump facilities, and connects our existing Mid-Continent infrastructure with our fractionation facility in Mont Belvieu, Texas, and other Gulf Coast region fractionators. We have NGL production dedicated from existing and new natural gas processing plants that we expect will be sufficient to fill the 210 MBbl/d capacity level over the next three to five years.

The demand for surface easements increased dramatically in Texas and Oklahoma over the last two years because of increased oil and natural gas exploration and production activities, as well as pipeline construction. As previously reported, project costs have been more expensive than originally estimated due to delays associated with right-of-way acquisition and difficult construction conditions associated with several weeks of heavy spring rains, resulting in greatly reduced construction productivity. We have also experienced increased costs due to a number of scope changes, arising primarily from additional supply development opportunities. We currently estimate project costs will be approximately $490 million, excluding AFUDC. We began filling the pipeline with product in July 2009, and expect to place the project in service in August 2009, with volumes reaching 65 MBbl/d by the end of the third quarter of 2009. This project is in our Natural Gas Liquids Pipelines segment.

Williston Basin Gas Processing Plant Expansion - The expansion of our Grasslands natural gas processing facility in North Dakota was placed in service in March 2009. The expansion increased processing capacity to approximately 100 MMcf/d from its previous capacity of 63 MMcf/d and increased fractionation capacity to approximately 12 MBbl/d from 8 MBbl/d. The cost of the project was approximately $46 million, excluding AFUDC. This project is in our Natural Gas Gathering and Processing segment.

Guardian Pipeline Expansion and Extension - In February 2009, we completed the 119-mile extension of our Guardian Pipeline. The pipeline has capacity to transport 537 MMcf/d of natural gas north from Ixonia, Wisconsin, to the Green Bay, Wisconsin, area. The project is supported by 15-year shipper commitments with We Energies and Wisconsin Public Service Corporation, and the capacity is close to fully subscribed. The project cost approximately $325 million, excluding AFUDC. This project is in our Natural Gas Pipelines segment.

IMPACT OF NEW ACCOUNTING STANDARDS

Information about the impact of the following new accounting standards is included in Note A of the Notes to Consolidated Financial Statements in this Quarterly Report:

·	Statement 160, “Noncontrolling Interests in Consolidated Financial Statements - an amendment of ARB No. 51;”

·	Statement 161, “Disclosures about Derivative Instruments and Hedging Activities - an amendment to FASB Statement No. 133;”

·	Statement 157, “Fair Value Measurements;”

·	EITF 07-4, “Application of the Two-Class Method under FASB Statement No. 128 to Master Limited Partnerships;”

·	FSP 107-1 and APB 28-1, “Interim Disclosures about Fair Value of Financial Instruments;”

·	Statement 165, “Subsequent Events;” and

·	Statement 168, “The FASB Accounting Standards Codification and the Hierarchy of Generally Accepted Accounting Principles.”

CRITICAL ACCOUNTING ESTIMATES

The preparation of our consolidated financial statements and related disclosures in accordance with GAAP requires us to make estimates and assumptions with respect to values or conditions that cannot be known with certainty that affect the reported amount of assets and liabilities, and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements. These estimates and assumptions also affect the reported amounts of revenues and expenses during the reporting period. Although we believe these estimates and assumptions are reasonable, actual results could differ from our estimates.

Information about our critical accounting estimates is included under Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations, “Critical Accounting Estimates,” in our Annual Report.

Impairment of Goodwill - We assess our goodwill for impairment at least annually. Our July 1, 2009, impairment test will be completed in the third quarter of 2009. As part of our impairment test, an initial assessment is made by comparing the fair value of a reporting unit with its book value, including goodwill. To estimate the fair value of our reporting units, we use two generally accepted valuation approaches, an income approach and a market approach. Under the income approach, we use anticipated cash flows over a period of years plus a terminal value and discount these amounts to their present value using appropriate rates of return. Under the market approach, we apply multiples to forecasted EBITDA amounts. The multiples used are consistent with historical asset transactions, and the EBITDA amounts are based on average EBITDA for a reporting unit over a three-year forecasted period.

There were no impairment charges resulting from our July 1, 2008, impairment test. As a result of events in the financial markets and deteriorating economic conditions following our July 1, 2008, impairment test, we performed subsequent reviews and determined that interim testing of goodwill was not indicated. Our estimates of fair value significantly exceeded the book value of our reporting units in our July 1, 2008, impairment test and our subsequent reviews. Even if the estimated fair values used in our impairment test were reduced by 10 percent, no impairment changes would have resulted from our July 1, 2008, impairment test. At June 30, 2009, and December 31, 2008, we had $396.7 million of goodwill recorded on our Consolidated Balance Sheets.

Derivatives and Risk Management - We utilize financial instruments to reduce our market risk exposure to commodity price and interest rate fluctuations and to achieve more predictable cash flows. We do not believe that changes in our fair value estimates of our derivative instruments have a material impact on our results of operations, as the majority of our derivatives are accounted for as cash flow hedges for which ineffectiveness is not material. See Notes B and C of the Notes to Consolidated Financial Statements in this Quarterly Report for additional discussion of our fair value measurements and derivatives and risk management activities.

Net margin decreased for the three and six months ended June 30, 2009, compared with the same period last year, primarily due to the following:

·	significantly lower realized commodity prices in our Natural Gas Gathering and Processing segment;

·	narrower product price differentials in our Natural Gas Liquids Gathering and Fractionation segment; and

·	the impact of lower natural gas prices on retained fuel in our Natural Gas Pipelines segment; partially offset by

·	increased NGL throughput primarily associated with the completion of the Overland Pass Pipeline and related expansion projects, as well as new supply connections in our Natural Gas Liquids Gathering and Fractionation segment and Natural Gas Liquids Pipelines segment;

·	incremental natural gas transportation margins from the Guardian Pipeline expansion and extension that was completed in February 2009 in our Natural Gas Pipelines segment; and

·	higher volumes processed and sold for the six months ended June 30, 2009, in our Natural Gas Gathering and Processing segment.

Operating costs increased for the three and six months ended June 30, 2009, compared with the same periods last year, primarily due to higher operating costs at our fractionation facilities, which included incremental operating expenses associated with the recently expanded Bushton Plant that resumed operations in the third quarter of 2008, and due to the operations of Overland Pass Pipeline that began in the fourth quarter of 2008.

Depreciation and amortization increased for the three and six months ended June 30, 2009, compared with the same periods last year, primarily due to higher depreciation expense associated with our completed capital projects.

Equity earnings from investments decreased for the three and six months ended June 30, 2009, compared with the same periods last year, primarily due to lower subscription volumes and rates on Northern Border Pipeline and decreased earnings from lower volumes gathered in our Natural Gas Gathering and Processing segment’s equity investments.

Interest expense increased for the three and six months ended June 30, 2009, compared with the same periods last year, primarily due to increased borrowings to fund our capital projects.

Capital expenditures decreased for the three and six months ended June 30, 2009, compared with the same periods last year, primarily due to the completion of the Overland Pass Pipeline and related expansion projects, the Williston Basin gas processing plant expansion and the Guardian Pipeline expansion and extension.

Natural Gas Gathering and Processing

Overview - Our Natural Gas Gathering and Processing segment’s operations include gathering of unprocessed natural gas produced from crude oil and natural gas wells. We gather unprocessed natural gas in the Mid-Continent region, which includes the Anadarko Basin of Oklahoma and the Hugoton and Central Kansas Uplift Basins of Kansas. We also gather unprocessed natural gas in two producing basins in the Rocky Mountain region: the Williston Basin, which spans portions of Montana, North Dakota and the Canadian province of Saskatchewan, and the Powder River Basin of Wyoming.

In the Mid-Continent and Rocky Mountain regions, unprocessed natural gas is compressed and transported through pipelines to processing facilities where volumes are aggregated, treated and 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. The residue gas, which consists primarily of methane, is compressed and delivered to natural gas pipelines for transportation to end users. When the NGLs are separated from the unprocessed natural gas at the processing plants, the NGLs are generally in the form of a mixed, unfractionated NGL stream. This unfractionated NGL stream is generally shipped to fractionators where, through the application of heat and pressure, the unfractionated NGL stream is separated into NGL products. Revenues for this segment are primarily derived from POP, fee and keep-whole contracts. Under a POP contract, we retain a portion of sales proceeds from the commodity sales for our services. With a fee-based contract, we charge a fee for our services, and with the keep-whole contract, we retain the NGLs as our fee for service and return to the producer an equivalent quantity of or payment for residue gas containing the same amount of Btus as the unprocessed natural gas that was delivered to us. Our natural gas and NGL products are sold to affiliates and a diverse customer base.

See Note C of the Notes to Consolidated Financial Statements in this Quarterly Report for more information on our hedging activities.

Commodity price risk related to estimated physical sales of commodities in our Natural Gas Gathering and Processing segment is estimated as a hypothetical change in the price of NGLs, crude oil and natural gas at June 30, 2009. Our condensate sales are based on the price of crude oil. We estimate the following:

·	a $0.01 per gallon decrease in the composite price of NGLs would decrease annual net margin by approximately $1.2 million;

·	a $1.00 per barrel decrease in the price of crude oil would decrease annual net margin by approximately $1.0 million; and

·	a $0.10 per MMBtu decrease in the price of natural gas would decrease annual net margin by approximately $0.7 million.

The above estimates of commodity price risk exclude the effects of hedging and assume normal operating conditions. Further, these estimates do not include any effects on demand for our services or changes in operations that might result from, or arise in conjunction with, price changes. For example, a change in the gross processing spread may cause a change in the amount of ethane we extract from the natural gas stream, impacting gathering and processing margins.

Our intrastate natural gas pipeline assets in Oklahoma have access to the major natural gas producing areas and transport natural gas throughout the state. We also have access to the major natural gas producing area in south central Kansas. In Texas, our intrastate natural gas pipelines are connected to the major natural gas producing areas in the Texas panhandle and the Permian Basin and transport natural gas to the Waha Hub, where other pipelines may be accessed for transportation east to the Houston Ship Channel market, north to the Mid-Continent market and west to the California market.

We own storage capacity in underground natural gas storage facilities in Oklahoma, Kansas and Texas.

Our transportation contracts for our regulated natural gas activities are based upon rates stated in our tariffs. Tariffs specify the maximum rates customers can be charged, which can be discounted to meet competition if necessary, and the general terms and conditions for pipeline transportation service, which are established at FERC or appropriate state jurisdictional agency proceedings known as rate cases. In Texas and Kansas, natural gas storage service is a fee business that may be regulated by the state in which the facility operates and by the FERC for certain types of services. In Oklahoma, natural gas gathering and natural gas storage operations are not subject to rate regulation and have market-based rate authority from the FERC for certain types of services.

Natural Gas Liquids Gathering and Fractionation

Overview - Our Natural Gas Liquids Gathering and Fractionation assets consist of facilities that gather, fractionate and treat NGLs and store NGL products primarily in Oklahoma, Kansas and Texas, as well as store and fractionate NGLs and NGL products in Mont Belvieu, Texas. The majority of the pipeline-connected natural gas processing plants in Oklahoma, Kansas and the Texas panhandle, which extract NGLs from unprocessed natural gas, are connected to our NGL gathering systems.

Most natural gas produced at the wellhead contains a mixture of NGL components, such as ethane, propane, iso-butane, normal 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 NGLs in the natural gas stream due to liquid and Btu content. The NGLs that are separated from the natural gas stream at the natural gas processing plants remain in a mixed, unfractionated form until they are gathered, primarily by pipeline, and delivered to fractionators where the NGLs are separated into NGL products. These NGL products are then stored or distributed to our customers, such as petrochemical manufacturers, heating fuel users, refineries and propane distributors.

Revenues for this segment are primarily derived from exchange services, optimization and marketing, isomerization and storage.

·	Our exchange services business primarily collects fees to gather, fractionate and treat unfractionated NGLs, thereby converting them into NGL products that are stored and shipped to a market center or customer-designated location.

Our optimization and marketing business utilizes our assets, contract portfolio and market knowledge to capture locational and seasonal price differentials. We move NGL products between Conway, Kansas, and Mont Belvieu, Texas, in order to capture the locational price differentials between the two market centers. Our NGL storage facilities are also utilized to capture seasonal price variances.

·	Our isomerization business captures the price differential when normal butane is converted into the more valuable iso-butane at an isomerization unit in Conway, Kansas. Iso-butane is used in the refining industry to increase the octane of motor gasoline.

·	Our storage business collects fees to store NGLs at our Mid-Continent and Mont Belvieu facilities.

Natural Gas Liquids Pipelines

Overview - Our Natural Gas Liquids Pipelines segment primarily owns and operates regulated natural gas liquids gathering and distribution pipelines and associated above- and below-ground NGL storage facilities. Our natural gas liquids gathering pipelines deliver unfractionated NGLs gathered in Oklahoma, Kansas, the Texas panhandle and the Rocky Mountain region to our Natural Gas Liquids Gathering and Fractionation segment’s Mid-Continent fractionation facilities in Oklahoma and Kansas. Our natural gas liquids distribution pipelines deliver unfractionated NGLs and NGL products to the natural gas liquids market hubs in Conway, Kansas, and Mont Belvieu, Texas. In addition, we own natural gas liquids distribution and refined petroleum products pipelines that connect our Mid-Continent assets with Midwest markets, including Chicago, Illinois. We operate FERC-regulated natural gas liquids gathering and distribution pipelines in Oklahoma, Kansas, Nebraska, Missouri, Iowa, Illinois, Indiana, Texas, Wyoming and Colorado and terminal and storage facilities in Missouri, Nebraska, Iowa and Illinois.

Revenues for this segment are primarily derived from transporting product under our FERC-regulated tariffs. Tariffs specify the rates we charge our customers and the general terms and conditions for NGL transportation service on our pipelines. Our tariffs include specifications regarding the receipt and delivery of NGLs at points along the pipeline systems. We generally charge tariff rates under a FERC-approved indexing methodology, which allows charging rates up to a prescribed ceiling that changes annually based on the year-to-year change in the Producer Price Index for finished goods. The FERC also permits interstate natural gas liquids pipelines to support rates by using a cost-of-service methodology or an agreement with a pipeline’s non-affiliated shipper.

Net margin increased for the six months ended June 30, 2009, compared with the same period last year, primarily as a result of the following:

an increase of $31.6 million due to increased volumes, primarily associated with the completion of the Overland Pass Pipeline and related expansion projects, including tariffs received from Natural Gas Liquids Gathering and Fractionation segment, as well as new supply connections; partially offset by

·	a decrease of $2.1 million due to lower storage margins related to the termination of certain storage contracts.

Operating costs and depreciation and amortization increased for the three and six months ended June 30, 2009, compared with the same periods last year, primarily due to the operations of the Overland Pass Pipeline and related expansion projects.

Contingencies

Legal Proceedings - We are a party to various litigation matters and claims that are in the normal 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. Additional information about our legal proceedings is included under Part II, Item 1, Legal Proceedings, of this Quarterly Report and under Part I, Item 3, Legal Proceedings, in our Annual Report.

LIQUIDITY AND CAPITAL RESOURCES

General - Part of our strategy is to grow through internally generated growth projects and acquisitions that strengthen and complement our existing assets. We have relied primarily on operating cash flow, bank credit facilities, debt issuances and the sale of common units for our liquidity and capital resources requirements. We fund our operating expenses, debt service and cash distributions to our limited partners and general partner primarily with operating cash flow. We expect to continue to use these sources for liquidity and capital resource needs on both a short- and long-term basis. We have no guarantees of debt or other similar commitments to unaffiliated parties.

During 2009, the capital markets have improved significantly from year-end 2008. During this period, we have continued to have access to our Partnership Credit Agreement to fund our short-term liquidity needs, and we have been able to access the debt and equity markets for our long-term financing needs.

We expect challenging economic conditions to persist for the remainder of 2009 and into 2010, with downward pressures, compared with 2008, on commodity prices. We also expect continued volatility and possible disruption in the financial markets, which could limit our access to those markets or increase the cost of issuing new securities in the future. Our ability to continue to access capital markets for debt and equity financing under reasonable terms depends on our financial condition, credit ratings and market conditions. We anticipate that our cash flow generated from operations, existing capital resources and ability to obtain financing will enable us to maintain our current level of operations and our planned operations, as well as capital expenditures.

Capital Structure - The following table sets forth our capitalization structure for the periods indicated.

Table of Contents

Cash Management - We use a centralized cash management program that concentrates the cash assets of our operating subsidiaries in joint accounts for the purpose of providing financial flexibility and lowering the cost of borrowing, transaction costs and bank fees. Our centralized cash management program provides that funds in excess of the daily needs of our operating subsidiaries are concentrated, consolidated or made available for use by other entities within our consolidated group. Our operating subsidiaries participate in this program to the extent they are permitted pursuant to FERC regulations or our operating agreements. Under the cash management program, depending on whether a participating subsidiary has short-term cash surpluses or cash requirements, the Intermediate Partnership provides cash to the subsidiary or the subsidiary provides cash to the Intermediate Partnership.

Short-term Liquidity - Our principal sources of short-term liquidity consist of cash generated from operating activities and borrowings under our Partnership Credit Agreement.

The total amount of short-term borrowings authorized by our general partner’s Board of Directors is $1.5 billion. At June 30, 2009, we had $360 million of borrowings outstanding and $586.5 million available under our Partnership Credit Agreement, which expires in March 2012, and available cash and cash equivalents of approximately $31.8 million. As of June 30, 2009, we could have issued $586.5 million of additional short- and long-term debt under the most restrictive provisions contained in our Partnership Credit Agreement. At June 30, 2009, we had a total of $49.2 million in letters of credit issued outside of the Partnership Credit Agreement.

Our Partnership Credit Agreement contains certain financial, operational and legal covenants as discussed in Note H of the Notes to Consolidated Financial Statements in our Annual Report. Among other things, these covenants include maintaining a ratio of indebtedness to adjusted EBITDA (EBITDA, as adjusted for all non-cash charges and increased for projected EBITDA from certain lender-approved capital expansion projects) of no more than 5 to 1. At June 30, 2009, our ratio of indebtedness to adjusted EBITDA was 4.3 to 1, and we were in compliance with all covenants under our Partnership Credit Agreement.

Long-term Financing - In addition to our principal sources of short-term liquidity discussed above, options available to us to meet our longer-term cash requirements include the issuance of common units or long-term notes. Other options to obtain financing include, but are not limited to, issuance of convertible debt securities and asset securitization, and the sale and leaseback of facilities.

We are subject to changes in the debt and equity markets, and there is no assurance we will be able or willing to access the public or private markets in the future. We may choose to meet our cash requirements by utilizing some combination of cash flows from operations, borrowing under existing credit facilities, altering the timing of controllable expenditures, restricting future acquisitions and capital projects, or pursuing other debt or equity financing alternatives. Some of these alternatives could involve higher costs or negatively affect our credit ratings, among other factors. Based on our investment-grade credit ratings, general financial condition and market expectations regarding our future earnings and projected cash flows, we believe that we will be able to meet our cash requirements and maintain our investment-grade credit ratings.

As a result of these transactions, ONEOK and its subsidiaries now hold an aggregate 45.1 percent interest in us.

We used the proceeds from the sale of common units and the general partner contributions to repay borrowings under our Partnership Credit Agreement and for general partnership purposes.

Table of Contents

Debt Issuance - In March 2009, we completed an underwritten public offering of $500 million aggregate principal amount of 8.625 percent Senior Notes due 2019. The 2019 Notes were issued under our existing shelf registration statement filed with the SEC.

The 2019 Notes are senior unsecured obligations, ranking equally in right of payment with all of our existing and future unsecured senior indebtedness, and effectively junior to all of the existing and future debt and other liabilities of our non-guarantor subsidiaries. The 2019 Notes are nonrecourse to our general partner. For more information regarding the 2019 Notes, refer to discussion in Note G of the Notes to Consolidated Financial Statements in this Quarterly Report.

Debt Covenants - The terms of the 2019 Notes are governed by an indenture, dated as of September 25, 2006, between us and Wells Fargo Bank, N.A., as trustee, as supplemented by the Fifth Supplemental Indenture, dated March 3, 2009 (Indenture). The Indenture does not limit the aggregate principal amount of debt securities that may be issued and provides that debt securities may be issued from time to time in one or more additional series. The Indenture contains covenants including, among other provisions, limitations on our ability to place liens on our property or assets and to sell and lease back our property.

Our $250 million and $225 million senior notes, due 2010 and 2011, respectively, contain provisions that require us to offer to repurchase the senior notes at par value if our Moody’s or S&P credit rating falls below investment grade (Baa3 for Moody’s or BBB- for S&P) and the investment-grade rating is not reinstated within a period of 40 days. Further, the indentures governing our senior notes due 2010 and 2011 include an event of default upon acceleration of other indebtedness of $25 million or more and the indentures governing our senior notes due 2012, 2016, 2019, 2036 and 2037 include an event of default upon the acceleration of other indebtedness of $100 million or more that would be triggered by such an offer to repurchase. Such events of default would entitle the trustee or the holders of 25 percent in aggregate principal amount of the outstanding senior notes due 2010, 2011, 2012, 2016, 2019, 2036 and 2037 to declare those notes immediately due and payable in full.

Capital Expenditures - Our capital expenditures are typically financed through operating cash flows, short- and long-term debt and the issuance of equity. Capital expenditures were $321.9 million and $524.6 million for the six months ended June 30, 2009 and 2008, respectively. We classify expenditures that are expected to generate additional revenue or significant operating efficiencies as growth capital expenditures. Maintenance capital expenditures are those required to maintain existing operations and do not typically generate additional revenues. Projected 2009 capital expenditures are significantly lower than 2008 capital expenditures due to the completion of the Overland Pass Pipeline and related expansion projects, the Williston Basin gas processing plant expansion and the Guardian Pipeline expansion and extension. Additional information about our growth capital expenditures is included under “Capital Projects” on page 24.

The following table summarizes our 2009 projected growth and maintenance capital expenditures, excluding AFUDC.

Credit Ratings - Our credit ratings as of June 30, 2009, are shown in the table below.

Rating Agency	Rating	Outlook
Moody’s	Baa2	Stable
S&P	BBB	Stable

Our credit ratings, which are currently investment grade, may be affected by a material change in our financial ratios or a material event affecting our business. The most common criteria for assessment of our credit ratings are the debt-to-EBITDA ratio, interest coverage, business risk profile and liquidity. We do not anticipate a downgrade in our credit ratings. However, if our credit ratings were downgraded, the interest rates on borrowings under our Partnership Credit Agreement would increase, resulting in an increase in our cost to borrow funds. An adverse rating change alone is not a default under our Partnership Credit Agreement but could trigger repurchase obligations with respect to certain of our long-term debt. See additional discussion about our credit ratings under “Debt Covenants.”

If our repurchase obligations are triggered, we may not have sufficient cash on hand to repurchase and repay any accelerated senior notes, which may cause us to borrow money under our credit facilities or seek alternative financing sources to finance the repurchases and repayment. We could also face difficulties accessing capital or our borrowing costs could increase, impacting our ability to obtain financing for acquisitions or capital expenditures, to refinance indebtedness and to fulfill our debt obligations.

Other than the note repurchase obligations described above under “Debt Covenants,” we have determined that we do not have significant exposure to rating triggers in various other contracts and equipment leases. Rating triggers are defined as provisions that would create an automatic default or acceleration of indebtedness based on a change in our credit rating.

In the normal course of business, our counterparties provide us with secured and unsecured credit. In the event of a downgrade in our credit rating or a significant change in our counterparties’ evaluation of our creditworthiness, we could be asked to provide additional collateral in the form of cash, letters of credit or other negotiable instruments.

Cash Distributions - We distribute 100 percent of our available cash, which generally consists of all cash receipts less adjustments for cash disbursements and net change to reserves, to our general and limited partners. Our income is allocated to our general partner and limited partners according to their partnership percentages of 2 percent and 98 percent, respectively. The effect of any incremental income allocations for incentive distributions to our general partner is calculated after the income allocation for the general partner’s partnership interest and before the income allocation to the limited partners.

The following table sets forth cash distributions paid, including our general partner’s incentive distribution interests, during the periods indicated.

	Six Months Ended
	June 30,
	2009		2008
	(Millions of dollars)
Common unitholders	$	117.6	$	104.2
Class B unitholders		78.8		75.4
General Partner		45.5		35.2
Total cash distributions paid before noncontrolling interests	$	241.9	$	214.8

For the six months ended June 30, 2009, cash distributions paid to our general partner included $40.6 million related to incentive distributions. These distributions pertained to the fourth quarter of 2008 and first quarter of 2009. In July 2009, we declared a cash distribution of $1.08 per unit ($4.32 per unit on an annualized basis) for the second quarter of 2009. The distribution will be paid on August 14, 2009, to unitholders of record as of July 31, 2009.

For the six months ended June 30, 2008, cash distributions paid to our general partner included $30.9 million related to incentive distributions. These distributions pertained to the fourth quarter of 2007 and first quarter of 2008.

Our general partner’s percentage interest in quarterly distributions increases after certain specified target levels are met. For additional information, see “Cash Distribution Policy” under Part II, Item 5, Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities, in our Annual Report.

Table of Contents

Commodity Prices - We are subject to commodity price volatility. Significant fluctuations in commodity prices may impact our overall liquidity due to the impact commodity price changes have on our cash flows from operating activities, including the impact on working capital for NGLs and natural gas held in storage, margin requirements and certain energy-related receivables. We believe that our available credit and cash and cash equivalents are adequate to meet liquidity requirements associated with commodity price volatility. See Note C of the Notes to Consolidated Financial Statements and the discussion under Natural Gas Gathering and Processing’s “Commodity Price Risk” in Item 2, Management’s Discussion and Analysis of Financial Condition and Results of Operations, in this Quarterly Report for information on our hedging activities.

CASH FLOW ANALYSIS

We use the indirect method to prepare our Consolidated Statements of Cash Flows. Under this method, we reconcile net income to cash flows provided by operating activities by adjusting net income for those items that impact net income but may not result in actual cash receipts or payments during the period. These reconciling items include depreciation and amortization, allowance for equity funds used during construction, gain on sale of assets, undistributed earnings from equity investments in excess of distributions received, and changes in our assets and liabilities not classified as investing or financing activities.

The following table sets forth the changes in cash flows by operating, investing and financing activities for the periods indicated.

	Six Months Ended						Increase (Decrease)
	June 30,						Six Months
	2009			2008			2009 vs. 2008
	(Millions of dollars)
Total cash provided by (used in):
Operating activities	$	189.4		$	329.9		$	(140.5	)	(43%)
Investing activities		(296.4	)		(515.5	)		219.1		43%
Financing activities		(38.8	)		258.8			(297.6	)	*
Change in cash and cash equivalents		(145.8	)		73.2			(219.0	)	*
Cash and cash equivalents at beginning of period		177.6			3.2			174.4		*
Cash and cash equivalents at end of period	$	31.8		$	76.4		$	(44.6	)	(58%)
* Percentage change is greater than 100 percent.

Operating Cash Flows - Operating cash flows are affected by earnings from our business activities. We provide services for producers and consumers of natural gas and NGLs. Changes in commodity prices and demand for our services or products, whether because of general economic conditions, changes in demand for the end products that are made with our products or increased competition from other service providers, could affect our earnings and operating cash flows.

Operating cash flows, before changes in operating assets and liabilities, were $257.5 million for the six months ended June 30, 2009, compared with $334.1 million for the same period last year. The decrease was primarily due to lower commodity prices, increased operating costs at our fractionation facilities and Overland Pass Pipeline, and increased interest expense as a result of our capital projects.

The changes in operating assets and liabilities decreased operating cash flows $68.0 million for the six months ended June 30, 2009, compared with a decrease of $4.1 million for the same period last year, primarily as a result of the following:

·	the impact of lower commodity prices on our operating assets and liabilities;

·	the timing of cash receipts from our revenues resulting in increased accounts receivable;

·	the timing of payments for purchases of commodities and other expenses resulting in increased accounts payable;and

·	the volume of commodities in storage.

Investing Cash Flows - Cash used in investing activities decreased for the six months ended June 30, 2009, compared with the same period last year, primarily due to the completion of the Overland Pass Pipeline and related expansion projects, the Williston Basin gas processing plant expansion and the Guardian Pipeline expansion and extension.

Financing Cash Flows - In March 2009, we completed an underwritten public offering of senior notes totaling approximately $498.3 million, net of discounts but before offering expenses. The net proceeds from the notes were used to repay borrowings under our Partnership Credit Agreement.

- 39 -

Table of Contents

In June 2009, our common unit offering generated net proceeds of approximately $219.9 million after deducting underwriting discounts but before offering expenses. In addition, ONEOK Partners GP contributed $4.7 million in order to maintain its 2 percent general partner interest in us. We used the proceeds and general partner contributions to repay borrowings under our Partnership Credit Agreement and for general partnership purposes. During the first six months of 2008, our common unit offering and private placement of common units generated proceeds of approximately $450.2 million. In addition, ONEOK Partners GP contributed $9.5 million in order to maintain its 2 percent general partner interest in us. We used a portion of the proceeds and general partner contributions to repay borrowings under our Partnership Credit Agreement.

Cash distributions to our general and limited partners during the first six months of 2009 were $241.9 million, compared with $214.8 million in the same period last year, an increase of $27.1 million. This increase was primarily due to additional units outstanding during 2009, as well as cash distributions of $2.16 per unit during the first six months of 2009, compared with $2.065 per unit for the same period last year.

Net repayments of notes payable were $510.0 million during the first six months of 2009, compared with net borrowings of $20 million for the same period last year.

ENVIRONMENTAL AND SAFETY MATTERS

Information about our environmental matters is included in Note H of the Notes to Consolidated Financial Statements in this Quarterly Report.

Pipeline Safety - We are subject to United States Department of Transportation regulations, including integrity management regulations. The Pipeline Safety Improvement Act requires pipeline companies to perform integrity assessments on pipeline segments that pass through densely populated areas or near specifically designated high consequence areas. To our knowledge, we are in compliance with all material requirements associated with the various pipeline safety regulations. Further, we cannot assure that existing pipeline safety regulations will not be revised or that new regulations will not be adopted that could result in increased compliance costs or additional operating restrictions.

Air and Water Emissions - The federal Clean Air Act, the federal Clean Water Act and analogous state laws impose restrictions and controls regarding the discharge of pollutants into the air and water in the United States. Under the Clean Air Act, a federally enforceable operating permit is required for sources of significant air emissions. We may be required to incur certain capital expenditures for air pollution-control equipment in connection with obtaining or maintaining permits and approvals for sources of air emissions. The Clean Water Act imposes substantial potential liability for the removal of pollutants discharged to waters of the United States and remediation of waters affected by such discharge. To our knowledge, we are in compliance with all material requirements associated with the various regulations.

The United States Congress is actively considering legislation to reduce greenhouse gas emissions, including carbon dioxide and methane. In addition, state and regional initiatives to regulate greenhouse gas emissions are under way. We are monitoring federal and state legislation to assess the potential impact on our operations. We estimate our direct greenhouse gas emissions annually as we collect all applicable greenhouse gas emission data for the previous year. Our most recent estimate, based on 2008 data, indicates that our emissions are less than 5 million metric tons of carbon dioxide equivalents on an annual basis. We will continue efforts to improve our ability to better quantify direct greenhouse gas emissions and will report such emissions as required by any mandatory reporting rule, including the rules anticipated to be issued by the United States Environmental Protection Agency (EPA) in late-2009.

Superfund - The Comprehensive Environmental Response, Compensation and Liability Act, also known as CERCLA or Superfund, imposes liability, without regard to fault or the legality of the original act, on certain classes of persons who contributed to the release of a hazardous substance into the environment. These persons include the owner or operator of a facility where the release occurred and companies that disposed or arranged for the disposal of the hazardous substances found at the facility. Under CERCLA, these persons may be liable for the costs of cleaning up the hazardous substances released into the environment, damages to natural resources and the costs of certain health studies.

Chemical Site Security - The United States Department of Homeland Security (Homeland Security) released an interim rule in April 2007 that requires companies to provide reports on sites where certain chemicals, including many hydrocarbon products, are stored. We completed the Homeland Security assessments, and our facilities were subsequently assigned one of four risked-based tiers ranging from high (Tier 1) to low (Tier 4) risk, or not tiered at all due to low risk. A majority of our facilities were not tiered. We are currently waiting for Homeland Security’s analysis to determine if any of the tiered facilities will require Site Security Plans and possible physical security enhancements. In addition, the Transportation Security Administration, along with the Department of Transportation, has completed a review and inspection of our “critical facilities” with no material issues.

Table of Contents

Environmental Footprint - Our environmental and climate change strategy focuses on taking steps to minimize the impact of our operations on the environment. These strategies include: (i) developing and maintaining an accurate greenhouse gas emissions inventory, according to rules anticipated to be issued by the EPA in late 2009, (ii) improving the efficiency of our various pipelines, natural gas processing facilities and natural gas liquids fractionation facilities, (iii) following developing technologies for emissions control, (iv) following developing technologies to capture carbon dioxide to keep it from reaching the atmosphere, and (v) analyzing options for future energy investment.

We participate in the EPA’s Natural Gas STAR Program to voluntarily reduce methane emissions. We were honored in 2008 as the “Natural Gas STAR Gathering and Processing Partner of the Year” for our efforts to positively address environmental issues through voluntary implementation of emission-reduction opportunities. In addition, we continue to focus on maintaining low rates of lost-and-unaccounted-for methane gas through expanded implementation of best practices to limit the release of methane gas during pipeline and facility maintenance and operations. Our 2008 calculation of our annual lost-and-unaccounted-for natural gas, for all of our business operations, is less than 1 percent of total throughput.

CONTROLS AND PROCEDURES

Quarterly Evaluation of Disclosure Controls and Procedures - As of the end of the period covered by this report, the Chief Executive Officer (Principal Executive Officer) and the Chief Financial Officer (Principal Financial Officer) of ONEOK Partners GP, our general partner, evaluated the effectiveness of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to management of ONEOK Partners GP, including the officers of ONEOK Partners GP who are the equivalent of our principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Based on their evaluation, they concluded that as of June 30, 2009, our disclosure controls and procedures were effective in ensuring that the information required to be disclosed by us in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

Changes in Internal Control Over Financial Reporting - We have made no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act) during the second quarter ended June 30, 2009, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II - OTHER INFORMATION

ITEM 1.

LEGAL PROCEEDINGS

Additional information about our legal proceedings is included under Part I, Item 3, Legal Proceedings, in our Annual Report.

Mont Belvieu Emissions, Texas Commission on Environmental Quality - As previously reported, we are in discussions with the Texas Commission on Environmental Quality (TCEQ) staff regarding air emissions at our Mont Belvieu fractionator, which may have exceeded the emissions allowed under our air permit. On March 13, 2009, the TCEQ issued a Notice of Enforcement, alleging that we failed to isolate the source of the emissions in a timely manner. In a letter dated April 15, 2009, the TCEQ proposed settling the matter by entering into an Agreed Order with an administrative penalty of $160,000 and requiring us to perform certain preventative procedures. On May 13, 2009, we submitted our response to the settlement proposal letter. While our response remained under consideration by the TCEQ staff, the time for accepting the settlement lapsed, and, in a letter dated June 24, 2009, the Enforcement Division of the TCEQ withdrew its settlement offer and referred the matter to its Litigation Division. This does not foreclose the possibility of a settlement, and we continue to communicate with the TCEQ staff in both divisions regarding resolution of this matter.
