NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

JUNE 30, 2011

(Unaudited)

NOTE 1 – BASIS OF PRESENTATION

Atlas Pipeline Partners, L.P. (the “Partnership”) is a publicly-traded (NYSE: APL) Delaware limited partnership engaged in the gathering and processing of natural gas in the Mid-Continent and Appalachia regions and the transportation of NGLs in the Mid-Continent. The Partnership’s operations are conducted through subsidiary entities whose equity interests are owned by Atlas Pipeline Operating Partnership, L.P. (the “Operating Partnership”), a wholly-owned subsidiary of the Partnership. At June 30, 2011, Atlas Pipeline Partners GP, LLC (the “General Partner”) owned a combined 2.0% general partner interest in the consolidated operations of the Partnership, through which it manages and effectively controls both the Partnership and the Operating Partnership. The remaining 98.0% ownership interest in the consolidated operations consists of limited partner interests. At June 30, 2011, the Partnership had 53,574,565 common units outstanding, including 1,641,026 common units held by the General Partner and 4,113,227 common units held by Atlas Energy, L.P., a publicly-traded partnership (NYSE: ATLS), formerly known as Atlas Pipeline Holdings, L.P. The General Partner is a wholly-owned subsidiary of Atlas Energy, L.P.

On February 17, 2011, Atlas Energy, Inc., a formerly publicly-traded company, completed an agreement and plan of merger with Chevron Corporation (“Chevron”), pursuant to which, among other things, Atlas Energy, Inc. became a wholly-owned subsidiary of Chevron (the “Chevron Merger”). At the time of the Chevron Merger, Atlas Energy, Inc. owned a 64.3% ownership interest in Atlas Energy, L.P.’s common units, and 1,112,000 of the Partnership’s common units, along with 8,000 $1,000 par value 12% cumulative Class C preferred limited partner units. The Partnership’s common units and 12% cumulative Class C preferred units held directly by Atlas Energy, Inc. were acquired by Chevron as part of the Chevron Merger. Atlas Energy, Inc. contributed Atlas Energy, L.P.’s general partner, Atlas Energy GP, LLC (formerly known as Atlas Pipeline Holdings GP, LLC) to Atlas Energy, L.P., so that Atlas Energy GP, LLC became Atlas Energy, L.P.’s wholly-owned subsidiary. In addition, Atlas Energy, Inc. distributed to its stockholders all Atlas Energy, L.P.’s common units that it held. On May 27, 2011, the Partnership redeemed the 8,000 $1,000 par value 12% cumulative Class C preferred limited partner units held by Chevron (see Note 5).

The Partnership has adjusted its consolidated financial statements and related footnote disclosures presented within this Form 10-Q from the amounts previously presented to reflect the September 16, 2010 sale of its Elk City and Sweetwater, Oklahoma natural gas gathering systems (collectively “Elk City”) (see Note 4). The Partnership has retrospectively adjusted its prior period consolidated financial statements to reflect the amounts related to the operations of Elk City as discontinued operations.

The accompanying consolidated financial statements, which are unaudited except that the balance sheet at December 31, 2010 is derived from audited financial statements, are presented in accordance with the requirements of Form 10-Q and accounting principles generally accepted in the United States for interim reporting. They do not include all disclosures normally made in financial statements contained in Form 10-K. In management’s opinion, all adjustments necessary for a fair presentation of the Partnership’s financial position, results of operations and cash flows for the periods disclosed have been made. These interim consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto presented in the Partnership’s Annual Report on Form 10-K for the year ended December 31, 2010. The results of operations for the six month period ended June 30, 2011 may not necessarily be indicative of the results of operations for the full year ending December 31, 2011.

NOTE 2 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

In addition to matters discussed further within this note, a more thorough discussion of the Partnership’s significant accounting policies is included in its audited consolidated financial statements and notes thereto in its Annual Report on Form 10-K for the year ended December 31, 2010.

Capitalized Interest

The Partnership capitalizes interest on borrowed funds related to capital projects only for periods that activities are in progress to bring these projects to their intended use. The weighted average interest rate used to capitalize interest on borrowed funds was 7.3% and 7.4% for the three months ended June 30, 2011 and 2010, respectively, and 7.7% and 7.4% for the six months ended June 30, 2011 and 2010, respectively. The amount of interest capitalized was $1.1 million and $0.2 million for the three months ended June 30, 2011 and 2010, respectively, and $1.3 million and $0.3 million for the six months ended June 30, 2011 and 2010, respectively.

Intangible Assets

The Partnership has recorded intangible assets with finite lives in connection with certain consummated acquisitions. The following table reflects the components of intangible assets being amortized at June 30, 2011 and December 31, 2010 (in thousands):


	June 30, 2011			December 31, 2010			Estimated Useful Lives In Years
Customer relationships:
Gross carrying amount	$	205,313		$	205,313		7–10
Accumulated amortization		(90,486	)		(78,934	)

Net carrying amount	$	114,827		$	126,379

The Partnership amortizes intangible assets with finite useful lives over their estimated useful lives. If an intangible asset has a finite useful life, but the precise length of that life is not known, that intangible asset must be amortized over the best estimate of its useful life. At a minimum, the Partnership will assess the useful lives of all intangible assets on an annual basis to determine if adjustments are required. The estimated useful life for the Partnership’s customer relationship intangible assets is based upon the estimated average length of non-contracted customer relationships in existence at the date of acquisition, adjusted for management’s estimate of whether these individual relationships will continue in excess or less than the average length. The weighted-average amortization period for customer relationships is 9.1 years. The Partnership recorded amortization expense on intangible assets of $5.8 million for both the three months ended June 30, 2011 and 2010, and $11.6 million for both the six months ended June 30, 2011 and 2010 on its consolidated statements of operations. Amortization expense related to intangible assets is estimated to be as follows for each of the next five calendar years: 2011 to 2013 - $23.1 million per year; 2014 - $19.5 million; 2015 - $14.5 million.

Stock-Based Compensation

All share-based payments to employees, including grants of employee stock options, are recognized in the financial statements based on their fair values and are generally accounted for as equity on the Partnership’s consolidated balance sheets. Share-based awards, which have a cash option, are classified as liabilities on the Partnership’s consolidated balance sheets. All other share-based awards are classified as equity on the Partnership’ consolidated balance sheets. Compensation expense associated

with share-based payments is recognized within general and administrative expenses on the Partnership’s statements of operations from the date of the grant through the date of vesting, amortized on a straight-line method. Generally, no expense is recorded for awards that do not vest due to forfeiture.

Net Income (Loss) Per Common Unit

Basic net income (loss) attributable to common limited partners per unit is computed by dividing net income (loss) attributable to common limited partners by the weighted average number of common limited partner units outstanding during the period. Net income (loss) attributable to common limited partners is determined by deducting net income attributable to participating securities, if applicable, and net income (loss) attributable to the General Partner’s and the preferred unitholders’ interests. The General Partner’s interest in net income (loss) is calculated on a quarterly basis based upon its 2% general partner interest and incentive distributions to be distributed for the quarter (see Note 6), with a priority allocation of net income to the General Partner’s incentive distributions, if any, in accordance with the partnership agreement, and the remaining net income (loss) allocated with respect to the General Partner’s and limited partners’ ownership interests.

The Partnership presents net income (loss) per unit under the two-class method for master limited partnerships, which considers whether the incentive distributions of a master limited partnership represent a participating security when considered in the calculation of earnings per unit under the two-class method. The two-class method considers whether the partnership agreement contains any contractual limitations concerning distributions to the incentive distribution rights that would impact the amount of earnings to allocate to the incentive distribution rights for each reporting period. If distributions are contractually limited to the incentive distribution rights’ share of currently designated available cash for distributions as defined under the partnership agreement, undistributed earnings in excess of available cash should not be allocated to the incentive distribution rights. Under the two-class method, management of the Partnership believes that the partnership agreement contractually limits cash distributions to available cash and, therefore, undistributed earnings are not allocated to the incentive distribution rights.

Unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and are included in the computation of earnings per unit pursuant to the two-class method. The Partnership’s phantom unit awards, which consist of common units issuable under the terms of its long-term incentive plans and incentive compensation agreements (see Note 13), contain non-forfeitable rights to distribution equivalents of the Partnership. The participation rights result in a non-contingent transfer of value each time the Partnership declares a distribution or distribution equivalent right during the award’s vesting period. However, unless the contractual terms of the participating securities require the holders to share in the losses of the entity, net loss is not allocated to the participating securities. As such, the net income (loss) utilized in the calculation of net income (loss) per unit must be after the allocation of only net income to the phantom units on a pro-rata basis.

The following is a reconciliation of net income (loss) from continuing operations and net income from discontinued operations allocated to the General Partner and common limited partners for purposes of calculating net income (loss) attributable to common limited partners per unit (in thousands):

Net income attributable to common limited partners’ ownership interest is allocated to the phantom units on a pro-rata basis (weighted average phantom units outstanding as a percentage of the sum of the weighted average phantom units and common limited partner units outstanding). For the three and six months ended June 30, 2010, net loss attributable to common limited partners’ ownership interest is not allocated to approximately 112,000 and 81,000 phantom units, respectively, because the contractual terms of the phantom units as participating securities do not require the holders to share in the losses of the entity.

Diluted net income (loss) attributable to common limited partners per unit is calculated by dividing net income (loss) attributable to common limited partners, plus income allocable to participating securities, by the sum of the weighted average number of common limited partner units outstanding plus the dilutive effect of outstanding participating securities and unit option awards, as calculated by the treasury stock method. Unit options consist of common units issuable upon payment of an exercise price by the participant under the terms of the Partnership’s long-term incentive plans (see Note 13).

The following table sets forth the reconciliation of the Partnership’s weighted average number of common limited partner units used to compute basic net income (loss) attributable to common limited partners per unit with those used to compute diluted net income (loss) attributable to common limited partners per unit (in thousands):


	Three Months Ended June 30,				Six Months Ended June 30,

(1)	For the three and six months ended June 30, 2010, approximately 112,000 and 81,000 phantom units, respectively, were excluded from the computation of diluted earnings attributable to common limited partners per unit because the inclusion of such phantom units would have been anti-dilutive.

(2)

For the three and six months ended June 30, 2010, 100,000 unit options were excluded from the computation of diluted earnings attributable to common limited partners per unit because the inclusion of such unit options would have been anti-dilutive. There were no unit options outstanding for the three and six months ended June 30, 2011.

Comprehensive Income

Comprehensive income includes net income (loss) and all other changes in the equity of a business during a period from transactions and other events and circumstances from non-owner sources. These changes, other than net income (loss), are referred to as “other comprehensive income” or “OCI” and for the Partnership only include changes in the fair value of unsettled derivative contracts which were previously accounted for as cash flow hedges (see Note 9). The following table sets forth the calculation of the Partnership’s comprehensive income (in thousands):

Revenue Recognition

The Partnership’s revenue primarily consists of the sale of natural gas and NGLs along with the fees earned from its gathering and processing operations. Under certain agreements, the Partnership purchases natural gas from producers and moves it into receipt points on its pipeline systems, and then sells the natural gas, or produced NGLs, if any, off of delivery points on its systems. Under other agreements, the Partnership gathers natural gas across its systems, from receipt to delivery point, without taking title to the natural gas. Revenue associated with the physical sale of natural gas is recognized upon physical delivery of the natural gas. In connection with the Partnership’s gathering and processing operations, it enters into the following types of contractual relationships with its producers and shippers:

Fee-Based Contracts. These contracts provide a set fee for gathering and/or processing raw natural gas. Revenue is a function of the volume of natural gas that the Partnership gathers and processes

and is not directly dependent on the value of the natural gas. The Partnership is also paid a separate compression fee on many of its systems. The fee is dependent upon the volume of gas flowing through its compressors and the quantity of compression stages utilized to gather the gas.

Percentage of Proceeds (“POP”) Contracts. These contracts provide for the Partnership to retain a negotiated percentage of the sale proceeds from residue gas and NGLs it gathers and processes, with the remainder being remitted to the producer. In this contract-type, the Partnership and the producer are directly dependent on the volume of the commodity and its value; the Partnership effectively owns a percentage of the commodity and revenues are directly correlated to its market value. POP contracts may include a fee component which is charged to the producer.

Keep-Whole Contracts. These contracts require the Partnership, as the processor and gatherer, to gather or purchase raw natural gas at current market rates. The volume of gas gathered or purchased is based on the measured volume at an agreed upon location (generally at the wellhead). The volume of gas redelivered or sold at the tailgate of the Partnership’s processing facility will be lower than the volume purchased at the wellhead primarily due to NGLs extracted when processed through a plant. The Partnership must make up or “keep the producer whole” for this loss in volume. To offset the make-up obligation, the Partnership retains the NGLs which are extracted and sells them for its own account. Therefore, the Partnership bears the economic risk (the “processing margin risk”) that (i) the volume of residue gas available for redelivery to the producer may be less than received from the producer; or (ii) the aggregate proceeds from the sale of the processed natural gas and NGLs could be less than the amount that the Partnership paid for the unprocessed natural gas. In order to help mitigate the risk associated with Keep-Whole contracts the Partnership generally imposes a fee to gather the gas that is settled under this arrangement. Also, because the natural gas volumes contracted under some Keep-Whole agreements is lower in BTU content and thus, can meet downstream pipeline specifications without being processed, the natural gas can be bypassed around the processing plants on these systems and delivered directly into downstream pipelines during periods of margin risk.

The Partnership accrues unbilled revenue due to timing differences between the delivery of natural gas, NGLs, and condensate and the receipt of a delivery statement. This revenue is recorded based upon volumetric data from the Partnership’s records and management estimates of the related gathering and compression fees which are, in turn, based upon applicable product prices. The Partnership had unbilled revenues at June 30, 2011 and December 31, 2010 of $67.2 million and $57.8 million, respectively, which are included in accounts receivable within its consolidated balance sheets.

Recently Issued Accounting Standards

In May 2011, the FASB issued Accounting Standards Update (“ASU”) 2011-04, “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs,” which, among other changes, requires (1) additional disclosures for fair value measurements categorized within Level 2 and Level 3 of the fair value hierarchy; and (2) additional disclosures for items that are not measured at fair value in the Partnership’s consolidated balance sheets but for which the fair value is required to be disclosed. These requirements are effective for interim and annual reporting periods beginning after December 15, 2011. Early adoption is prohibited. The Partnership will apply these requirements upon the adoption of this ASU on December 31, 2011. The Partnership does not expect the adoption to have a material impact on its financial position and results of operations.

In June 2011, the FASB issued ASU 2011-05, “Comprehensive Income (Topic 220) – Presentation of Comprehensive Income,” which, among other changes, eliminates the option to present components of other comprehensive income as part of the statement of changes in equity. The amendments in this update require that “all nonowner changes in equity be presented either in a single

continuous statement of comprehensive income or in two separate but consecutive statements.” The update does not change the components of comprehensive income that must be presented. These requirements are effective for interim and annual reporting periods beginning after December 15, 2011. Early adoption is permitted. The Partnership will apply these requirements upon the adoption of this ASU on December 31, 2011. The Partnership does not expect the adoption to have a material impact on its financial position and results of operations.

NOTE 3 – INVESTMENT IN JOINT VENTURES

Laurel Mountain

On February 17, 2011, the Partnership completed the sale of its 49% non-controlling interest in Laurel Mountain Midstream, LLC (“Laurel Mountain”), a Delaware limited liability company, to Atlas Energy Resources, LLC (“Atlas Energy Resources”), a wholly-owned subsidiary of Atlas Energy, Inc. (the “Laurel Mountain Sale”) for $409.5 million in cash, including closing adjustments and net of expenses. Concurrently, Atlas Energy, Inc. became a wholly-owned subsidiary of Chevron and divested its interests in Atlas Energy, L.P. (see Note 1), resulting in the Laurel Mountain sale being classified as a third party sale. The Partnership recognized on its consolidated statements of operations a net gain on the sale of assets of $253.5 million. The Partnership recognized a $0.3 million loss during the three months ended June 30, 2011 for expenses related to the sale and recognized a $255.7 million gain during the six months ended June 30, 2011. A $2.2 million loss was also recognized during the year ended December 31, 2010 for expenses related to the sale. Laurel Mountain is a joint venture, which owns and operates the Appalachia natural gas gathering system previously owned by the Partnership. Subsidiaries of The Williams Companies, Inc. (NYSE: WMB) (“Williams”) hold the remaining 51% ownership interest. The Partnership utilized the proceeds from the sale to repay its indebtedness (see Note 11) and for general company purposes.

The Partnership recognized its 49% non-controlling ownership interest in Laurel Mountain as an investment in joint venture on its consolidated balance sheets at fair value. The Partnership accounted for its ownership interest in Laurel Mountain under the equity method of accounting, with recognition of its ownership interest in the income of Laurel Mountain as equity income on its consolidated statements of operations. Since the Partnership accounted for its ownership as an equity investment, the Partnership did not reclassify the earnings or the gain on sale related to Laurel Mountain to discontinued operations upon the sale of its ownership interest.

The Partnership retained its preferred distribution rights with respect to an $8.5 million note receivable due from Williams, an investment grade rated entity, related to the formation of Laurel Mountain in 2009, including interest due on this note. Interest is received on the last day of each quarter. The preferred distribution rights with respect to the note receivable have been reclassified from investment in joint venture to notes receivable on the Partnership’s consolidated balance sheets. Any amount that remains outstanding on this note after June 1, 2012 will be paid to the Partnership in cash.

West Texas LPG Pipeline Limited Partnership

On May 11, 2011, the Partnership acquired a 20% interest in West Texas LPG Pipeline Limited Partnership (“WTLPG”) from Buckeye Partners, L.P. (NYSE: BPL) for $85.0 million. WTLPG owns a 2,295 mile common-carrier pipeline system that transports NGLs from New Mexico and Texas to Mont Belvieu, Texas for fractionation. WTLPG is operated by Chevron Pipeline Company, an affiliate of Chevron, which owns the remaining 80% interest. The Partnership recognizes its 20% interest in WTLPG as an investment in joint venture on its consolidated balance sheets. The Partnership accounts for its ownership interest in WTLPG under the equity method of accounting, with recognition of its

ownership interest in the income of WTLPG as equity income on its consolidated statements of operations. The Partnership incurred costs of $0.6 million during the three and six months ended June 30, 2011, related to the acquisition of WTLPG, which are reported as other costs within the Partnership’s consolidated statements of operations.

The following tables summarize the components of the investment in joint ventures on the Partnership’s consolidated balance sheets and the components of equity income on the Partnership’s statements of operations (in thousands).

NOTE 4 – DISCONTINUED OPERATIONS

On September 16, 2010, the Partnership completed the sale of its Elk City and Sweetwater, Oklahoma natural gas gathering systems, and the related processing and treating facilities (including the Prentiss treating facility and the Nine Mile processing plant, collectively, “Elk City”) to a subsidiary of Enbridge Energy Partners, L.P. (NYSE: EEP) for $682.0 million in cash, excluding working capital adjustments and transaction costs, and recognized a gain of $312.1 million on the sale of Elk City within income from discontinued operations on its consolidated statements of operations, during the year ended December 31, 2010. During the six months ended June 30, 2011, the Partnership recorded, within its consolidated statements of operations, a reduction to the gain on sale of Elk City of $81 thousand to recognize the final settlement of working capital adjustments and transaction costs. The Partnership accounted for the earnings of Elk City as discontinued operations within its consolidated financial statements. Elk City was previously included within the Partnership’s formerly reported Mid-Continent segment of operations, which was reclassified to the Partnership’s current processing and gathering segment of operations.

The following table summarizes the components included within income from discontinued operations on the Partnership’s consolidated statements of operations (in thousands):


	Three Months Ended					Six Months Ended

Loss on asset sales and other		—		—			(81	)		—

Income (loss) from discontinued operations	$	—	$	7,976		$	(81	)	$	14,757

The Partnership’s continuing operations include $17.0 million and $17.4 million within natural gas and liquids revenue on the consolidated statements of operations for the three and six months ended June 30, 2010, respectively, for intercompany sales from the Chaney Dell system to Elk City, which were previously eliminated on the Partnership’s consolidated statement of operations. In periods subsequent to the sale of Elk City, these sales have been and will be made directly to third parties.

NOTE 5 – PREFERRED UNIT EQUITY OFFERINGS

On June 30, 2010, the Partnership sold 8,000 newly-created 12% Cumulative Class C Preferred Units of limited partner interest (the “Class C Preferred Units”) to Atlas Energy, Inc. for cash consideration of $1,000 per Class C Preferred Unit (the “Class C Preferred Unit Face Value”). The Class C Preferred Units were entitled to receive distributions of 12.0% per annum, paid quarterly on the same date as the distribution payment date for the Partnership’s common units. The Class C Preferred Units were not convertible into common units of the Partnership. The Partnership had the right at any time to redeem some or all of the outstanding Class C Preferred Units for cash at an amount equal to the Class C Preferred Face Value being redeemed plus accrued but unpaid dividends.

On February 17, 2011, the Class C Preferred Units were acquired by Chevron as part of the Chevron Merger (see Note 1). On May 27, 2011, the Partnership redeemed all 8,000 Class C Preferred Units outstanding for cash at the liquidation value of $1,000 per unit, or $8.0 million, plus $0.2 million, representing the accrued dividends on the 8,000 Class C Preferred Units prior to the Partnership’s redemption. There are no longer any Class C Preferred Units outstanding. The Partnership recognized $0.2 million and $0.4 million of preferred dividends for the three and six months ended June 30, 2011, respectively, which are presented as reductions of net income (loss) to determine net income (loss) attributable to common limited partners and the General Partner on its consolidated statements of operations.

NOTE 6 – CASH DISTRIBUTIONS

The Partnership is required to distribute, within 45 days after the end of each quarter, all of its available cash (as defined in its partnership agreement) for that quarter to its common unitholders and the General Partner. If common unit distributions in any quarter exceed specified target levels, the General Partner will receive between 15% and 50% of such distributions in excess of the specified target levels. Common unit and General Partner distributions declared by the Partnership from January 1, 2010 through June 30, 2011 were as follows:


For Quarter Ended	Date Cash Distribution Paid	Cash Distribution Per Common Limited Partner Unit		Total Cash Distribution to Common Limited Partners		Total Cash Distribution to the General Partner
				(in thousands)		(in thousands)
March 31, 2010	None	$	0.00	$	—	$	—

March 31, 2011	May 13, 2011		0.40		21,400		439

On July 26, 2011, the Partnership declared a cash distribution of $0.47 per unit on its outstanding common limited partner units, representing the cash distribution for the quarter ended June 30, 2011. The $26.2 million distribution, including $1.0 million to the General Partner for its general partner interest and incentive distribution rights, will be paid on August 12, 2011 to unitholders of record at the close of business on August 5, 2011.

NOTE 7 – PROPERTY, PLANT AND EQUIPMENT

The following is a summary of property, plant and equipment (in thousands):


	June 30, 2011			December 31, 2010			Estimated Useful Lives in Years
Pipelines, processing and compression facilities	$	1,437,321		$	1,340,944		2 – 40
Rights of way		157,677			156,713		20 – 40

		1,625,903			1,527,344
Less – accumulated depreciation		(212,799	)		(186,342	)

	$	1,413,104		$	1,341,002

Property, plant and equipment are stated at cost or, upon acquisition of a business, at the fair value of the assets acquired. Maintenance and repairs are expensed as incurred. Major renewals and improvements that extend the useful lives of property are capitalized. Depreciation and amortization expense is based on cost less the estimated salvage value primarily using the straight-line method over the asset’s estimated useful life. The Partnership follows the composite method of depreciation and has determined the composite groups to be the major asset classes of its gathering and processing systems. Under the composite depreciation method, any gain or loss upon disposition or retirement of pipeline, gas gathering and processing components is recorded to accumulated depreciation. When entire pipeline systems, gas plants or other property and equipment are retired or sold, any gain or loss is included in the Partnership’s results of operations. The Partnership recorded depreciation expense on property, plant and equipment of $13.3 million and $12.8 million for the three months ended June 30, 2011 and 2010, respectively, and $26.4 million and $25.5 million for the six months ended June 30, 2011 and 2010, respectively, on its consolidated statements of operations.

During the six months ended June 30, 2010, the Partnership entered into capital lease arrangements having obligations of $0.9 million at inception. Leased property and equipment meeting capital lease criteria are capitalized at the original cost of the equipment and are included within property plant and equipment on the Partnership’s consolidated balance sheets. Amortization is calculated on a straight-line method based upon the estimated useful lives of the assets. The Partnership did not enter into any capital lease arrangements during the six months ended June 30, 2011.

NOTE 8 – OTHER ASSETS

The following is a summary of other assets (in thousands):


	June 30,		December 31,
	2011		2010
Deferred finance costs, net of accumulated amortization of $31,929 and $24,436 at June 30, 2011 and December 31, 2010, respectively	$	18,967	$	26,227
Security deposits		2,458		2,841

	$	21,425	$	29,068

Deferred finance costs are recorded at cost and amortized over the term of the respective debt agreement (see Note 11). During the three and six months ended June 30, 2011, the Partnership recorded $5.2 million related to accelerated amortization of deferred financing costs associated with the retirement of its 8.125% Senior Notes and partial redemption of its 8.75% Senior Notes. This expense is included in

loss on early extinguishment of debt on the Partnership’s consolidated statements of operations (see Note 11). Amortization expense of deferred finance costs was $1.0 million and $1.6 million for the three months ended June 30, 2011 and 2010, respectively, and $2.3 million and $3.2 million for the six months ended June 30, 2011 and 2010, respectively, which is recorded within interest expense on the Partnership’s consolidated statements of operations. Amortization expense related to deferred finance costs is estimated to be as follows for each of the next five calendar years: 2011 - $4.3 million; 2012 to 2014 - $4.0 million per year; 2015 - $3.7 million.

NOTE 9 – DERIVATIVE INSTRUMENTS

The Partnership uses derivative instruments in connection with its commodity price risk management activities. The Partnership enters into financial swap and option instruments to hedge its forecasted natural gas, NGLs and condensate sales against the variability in expected future cash flows attributable to changes in market prices. It also previously entered into financial swap instruments to hedge certain portions of its floating interest rate debt against the variability in market interest rates. Swap instruments are contractual agreements between counterparties to exchange obligations of money as the underlying natural gas, NGLs and condensate are sold or interest payments on the underlying debt instrument are due. Under its swap agreements, the Partnership receives a fixed price and remits a floating price based on certain indices for the relevant contract period. The swap agreement sets a fixed price for the product being hedged. Commodity-based option instruments are contractual agreements that require the payment of a premium and grant the purchaser of the option the right to receive the difference between a fixed, or strike, price and a floating price based on certain indices for the relevant contract period, if the floating price is lower than the fixed price. The option agreement sets a floor price for commodity sales being hedged.

The Partnership no longer applies hedge accounting for its derivatives. As such, changes in fair value of derivatives are recognized immediately within other income (loss), net in its consolidated statements of operations. The change in fair value of commodity-based derivative instruments, which was previously recognized in accumulated other comprehensive loss within Equity on the Partnership’s consolidated balance sheets, will be reclassified to the Partnership’s consolidated statements of operations in the future at the time the originally hedged physical transactions affect earnings. The Partnership will reclassify $5.3 million of the $7.8 million net loss in accumulated other comprehensive loss, within Equity on the Partnership’s consolidated balance sheets at June 30, 2011, to natural gas and liquids revenue on the Partnership’s consolidated statements of operations over the next twelve-month period. Aggregate losses of $2.5 million will be reclassified to natural gas and liquids revenue on the Partnership’s consolidated statements of operations in later periods.

Derivatives are recorded on the Partnership’s consolidated balance sheets as assets or liabilities at fair value. Premium costs for purchased options are recorded on the Partnership’s consolidated balance sheets as the initial value of the options. Changes in the fair value of the options are recognized within other income (loss), net as unrealized gain (loss) on the Partnership’s consolidated statements of operations. Premium costs are reclassified to realized gain (loss) within other income (loss), net at the time the option expires or is exercised. The Partnership reflected net derivative liabilities on its consolidated balance sheets of $3.0 million and $10.2 million, at June 30, 2011 and December 31, 2010, respectively.

The fair value of the Partnership’s derivative instruments was included in its consolidated balance sheets as follows (in thousands):

NOTE 10 – FAIR VALUE OF FINANCIAL INSTRUMENTS

Derivative Instruments

The Partnership uses a valuation framework based upon inputs that market participants use in pricing an asset or liability, which are classified into two categories: observable inputs and unobservable inputs. Observable inputs represent market data obtained from independent sources; whereas, unobservable inputs reflect the Partnership’s own market assumptions, which are used if observable inputs are not reasonably available without undue cost and effort. These two types of inputs are further prioritized into the following hierarchy:

Level 1– Unadjusted quoted prices in active markets for identical, unrestricted assets and liabilities that the reporting entity has the ability to access at the measurement date.

Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset and liability or can be corroborated with observable market data for substantially the entire contractual term of the asset or liability.

Level 3 – Unobservable inputs that reflect the entity’s own assumptions about the assumption that market participants would use in the pricing of the asset or liability and are consequently not based on market activity but rather based upon particular valuation techniques.

The Partnership uses a fair value methodology to value the assets and liabilities for its outstanding derivative contracts (see Note 9). At June 30, 2011, all of the Partnership’s derivative contracts are defined as Level 2, with the exception of the Partnership’s NGL fixed price swaps and NGL options. The Partnership’s Level 2 commodity derivatives include natural gas and crude oil swaps and options which are calculated based upon observable market data related to the change in price of the underlying commodity. These swaps and options are calculated by utilizing the New York Mercantile Exchange (“NYMEX”) quoted price for futures and option contracts traded on NYMEX that coincide with the underlying commodity, expiration period, strike price (if applicable) and pricing formula. Valuations for the Partnership’s NGL fixed price swaps are based on a forward price curve modeled on a regression analysis of quoted price curves for NGL’s for similar locations, and therefore are defined as Level 3. Valuations for the Partnership’s NGL options are based on forward price curves developed by financial institutions, and therefore are defined as Level 3.

The following table represents the Partnership’s derivative assets and liabilities recorded at fair value as of June 30, 2011 and December 31, 2010 (in thousands):

Other Financial Instruments

The estimated fair value of the Partnership’s other financial instruments has been determined based upon its assessment of available market information and valuation methodologies. However, these estimates may not necessarily be indicative of the amounts that the Partnership could realize upon the sale or refinancing of such financial instruments.

The Partnership’s current assets and liabilities on its consolidated balance sheets, other than the derivatives discussed above, are considered to be financial instruments for which the estimated fair values

of these instruments approximate their carrying amounts due to their short-term nature. The estimated fair values of the Partnership’s total debt at June 30, 2011 and December 31, 2010, which consists principally of borrowings under the revolving credit facility, the 8.125% Senior Notes and the 8.75% Senior Notes, were $344.0 million and $532.3 million, respectively, compared with the carrying amounts of $359.0 million and $566.0 million, respectively. The Senior Notes were valued based upon available market data for similar issues. The carrying value of outstanding borrowings under the revolving credit facility, which bear interest at a variable interest rate, approximate their estimated fair value.

NOTE 11 – DEBT

Total debt consists of the following (in thousands):


	June 30,			December 31,
	2011			2010
Revolving credit facility	$	142,500		$	70,000
8.125% Senior notes – due 2015		—			272,181
8.75% Senior notes – due 2018		215,822			223,050

Less current maturities		(217	)		(210	)

Total long term debt	$	358,744		$	565,764

Cash payments for interest related to debt, net of capitalized interest, were $16.5 million and $37.0 million for the three months ended June 30, 2011 and 2010, respectively, and $17.2 million and $54.9 million for the six months ended June 30, 2011 and 2010, respectively.

Revolving Credit Facility

At June 30, 2011, the Partnership had a $350.0 million senior secured revolving credit facility with a syndicate of banks, which matures in December 2015. On July 8, 2011, the revolving credit facility was increased to $450.0 million (see Note 17). Borrowings under the revolving credit facility bear interest, at the Partnership’s option, at either (i) the higher of (a) the prime rate, (b) the federal funds rate plus 0.50% and (c) three-month LIBOR plus 1.0%, or (ii) the LIBOR rate for the applicable period (each plus the applicable margin). The weighted average interest rate for borrowings on the revolving credit facility, at June 30, 2011, was 3.2%. Up to $50.0 million of the revolving credit facility may be utilized for letters of credit, of which $1.7 million was outstanding at June 30, 2011. These outstanding letter of credit amounts were not reflected as borrowings on the Partnership’s consolidated balance sheets. At June 30, 2011, the Partnership had $205.8 million of remaining committed capacity under its revolving credit facility.

Borrowings under the revolving credit facility are secured by a lien on and security interest in all of the Partnership’s property and that of its subsidiaries, except for the assets owned by Chaney Dell and Midkiff/Benedum joint ventures; and by the guaranty of each of the Partnership’s consolidated subsidiaries other than the joint venture companies. The revolving credit facility contains customary covenants, including restrictions on the Partnership’s ability to incur additional indebtedness; make certain acquisitions, loans or investments; make distribution payments to its unitholders if an event of default exists; or enter into a merger or sale of assets, including the sale or transfer of interests in its subsidiaries. The Partnership is also unable to borrow under its revolving credit facility to pay distributions of available cash to unitholders because such borrowings would not constitute “working capital borrowings” pursuant to its partnership agreement.

The events which constitute an event of default for the revolving credit facility are also customary for loans of this size, including payment defaults, breaches of representations or covenants contained in the credit agreement, adverse judgments against the Partnership in excess of a specified amount, and a change of control of the Partnership’s General Partner. As of June 30, 2011, the Partnership was in compliance with all covenants under the revolving credit facility.

Senior Notes

At June 30, 2011, the Partnership had $215.8 million principal amount outstanding of 8.75% senior unsecured notes due on June 15, 2018 (“8.75% Senior Notes”). Interest on the 8.75% Senior Notes is payable semi-annually in arrears on June 15 and December 15. The 8.75% Senior Notes are redeemable at any time after June 15, 2013, at certain redemption prices, together with accrued and unpaid interest to the date of redemption. The 8.75% Senior Notes are subject to repurchase by the Partnership at a price equal to 101% of their principal amount, plus accrued and unpaid interest, upon a change of control or upon certain asset sales if the Partnership does not reinvest the net proceeds within 360 days. The 8.75% Senior Notes are junior in right of payment to the Partnership’s secured debt, including the Partnership’s obligations under its revolving credit facility.

On April 7, 2011, the Partnership redeemed $7.2 million of the 8.75% Senior Notes, which were tendered upon its offer to purchase the 8.75% Senior Notes, at par. The sale of the Partnership’s 49% non-controlling interest in Laurel Mountain on February 17, 2011 constituted an “Asset Sale” pursuant to the terms of the indenture of the 8.75% Senior Notes. As a result of the Asset Sale, the Partnership offered to purchase any and all of the 8.75% Senior Notes.

The indenture governing the 8.75% Senior Notes contains covenants, including limitations of the Partnership’s ability to: incur certain liens; engage in sale/leaseback transactions; incur additional indebtedness; declare or pay distributions if an event of default has occurred; redeem, repurchase or retire equity interests or subordinated indebtedness; make certain investments; or merge, consolidate or sell substantially all of its assets. The Partnership is in compliance with these covenants as of June 30, 2011.

On April 8, 2011, the Partnership redeemed all of the 8.125% senior unsecured notes due on December 15, 2015 (“8.125% Senior Notes”). The redemption price was determined in accordance with the indenture for the 8.125% Senior Notes, plus accrued and unpaid interest thereon to the redemption date. The Partnership paid $293.7 million to redeem the $275.5 million principal plus $11.2 million premium and $7.0 million accrued interest. There were no 8.125% Senior Notes outstanding at June 30, 2011.

NOTE 12 – COMMITMENTS AND CONTINGENCIES

The Partnership has certain long-term unconditional purchase obligations and commitments, primarily take-or-pay agreements. These agreements provide transportation services to be used in the ordinary course of the Partnership’s operations.

The Partnership is, or may become, a party to various routine legal proceedings arising out of the ordinary course of its business. Management of the Partnership believes that the ultimate resolution of these actions, individually or in the aggregate, will not have a material adverse effect on its financial condition or results of operations.

On February 26, 2010, the Partnership received notice from Williams, its former joint venture partner in Laurel Mountain, alleging that certain title defects exist with respect to the real property contributed by the Partnership to Laurel Mountain. Under the Formation and Exchange Agreement with

Williams (“Formation Agreement”): (i) Williams had nine months after closing (the “Claim Date”) to assert any alleged title defects, and (ii) the Partnership had 30 days following the Claim Date to contest the title defects asserted by Williams and 180 days following the Claim Date to cure those title defects, which was extended by agreement until March 31, 2011. On March 26, 2010, the Partnership delivered notice, disputing Williams’ alleged title defects as well as the amounts claimed. The Partnership has delivered documentation to Williams, which should resolve many of the alleged title defects. Although the Partnership’s cure period has technically expired, the Partnership, without objection from Williams, continues work to resolve the remaining alleged title defects. In addition, Atlas Energy, Inc. delivered a proposed assignment to Laurel Mountain that should resolve some of the alleged deficiencies. Williams also claims, in a letter dated August 26, 2010, that the alleged title defects violate the Partnership’s representation with respect to sufficiency of the assets contributed to Laurel Mountain. If valid, this would make Williams’ title defect claims subject to a higher aggregate cap (which is noted below). The Partnership believes its representations with respect to title are Williams’ sole and exclusive remedy with respect to title matters.

In August 2010, Williams asserted additional indemnity claims under the Formation Agreement totaling approximately $19.8 million. Williams’ claims are generally based on the Partnership’s alleged failure to construct and maintain the assets contributed to Laurel Mountain in accordance with “standard industry practice” or applicable law. As a preliminary matter, the Partnership believes Williams has overstated its claim by forty-nine percent (49%), because, under the Formation Agreement, these claims are reduced on a pro-rata basis to equal Williams’ percentage ownership interest in Laurel Mountain. The Partnership has received some additional information from Williams and, based on the Partnership’s analysis of that information, believes that an adverse outcome is probable with respect to some portion of Williams’ claims.

There were no substantive developments with respect to Williams’ indemnity claims during the three months ended June 30, 2011. As previously reported, the Partnership has established an accrual with respect to the portion of Williams’ claims that it deems probable, which is less than 51% of the amounts asserted by Williams. Under the Formation Agreement, Williams’ indemnity claims are capped, in the aggregate, at $27.5 million. In addition, the Partnership may be entitled to indemnification from Atlas Energy, Inc. with respect to a small portion of Williams’ claims.

NOTE 13 – BENEFIT PLANS

Generally, all share-based payments to employees, which are not cash settled, including grants of unit options and phantom units, are recognized within equity in the financial statements based on their fair values on the date of the grant. Share-based payments to non-employees, which have a cash settlement option, are recognized within liabilities in the financial statements based upon their current fair market value.

A phantom unit entitles a grantee to receive a common limited partner unit upon vesting of the phantom unit. In tandem with phantom unit grants, participants may be granted a distribution equivalent right (“DER”), which is the right to receive cash per phantom unit in an amount equal to and at the same time as the cash distributions the Partnership makes on a common unit during the period the phantom unit is outstanding. Except for phantom units awarded to non-employee managing board members of the General Partner and within the guidelines proscribed in each long term incentive plan, a committee (the “LTIP Committee”) appointed by the General Partner’s managing board determines the vesting period for phantom units.

A unit option entitles a grantee to purchase a common limited partner unit upon payment of the exercise price for the option after completion of vesting of the unit option. The exercise price of the unit

option is equal to the fair market value of the common unit on the date of grant of the option. The LTIP Committee shall determine how the exercise price may be paid by the grantee. The LTIP Committee will determine the vesting and exercise period for unit options. Unit option awards expire 10 years from the date of grant.

Long-Term Incentive Plans

The Partnership has a 2004 Long-Term Incentive Plan (“2004 LTIP”) and a 2010 Long-Term Incentive Plan, which was modified on April 26, 2011 (“2010 LTIP” and collectively with the 2004 LTIP, the “LTIPs”), in which officers, employees, non-employee managing board members of the General Partner, employees of the General Partner’s affiliates and consultants are eligible to participate. The LTIPs are administered by the LTIP Committee. Under the LTIPs, the LTIP Committee may make awards of either phantom units or unit options for an aggregate of 3,435,000 common units. At June 30, 2011, the Partnership had 436,425 phantom units outstanding under the Partnership’s LTIPs, with 2,370,494 phantom units and unit options available for grant. The Partnership generally issues new common units for phantom units and unit options, which have vested and have been exercised.

Partnership Phantom Units. Through June 30, 2011, phantom units granted to employees under the LTIPs generally had vesting periods of four years. Phantom units awarded to non-employee managing board members will vest over a four year period. Awards may automatically vest upon a change of control, as defined in the LTIPs. At June 30, 2011, there were 193,195 units outstanding under the LTIPs that will vest within the following twelve months. The Partnership is authorized to repurchase common units to cover employee-related taxes on certain phantom units, when they have vested. The Partnership repurchased and retired 23,345 common units for a cost of $813 thousand during the three and six months ended June 30, 2011, which was recorded as a reduction of Partners’ capital on the Partnership’s consolidated balance sheet. On February 17, 2011, the employment agreement with the Chief Executive Officer (“CEO”) of the General Partner was terminated in connection with the Chevron Merger (see Note 1) and 75,250 outstanding phantom units, which represents all outstanding phantom units held by the CEO, automatically vested and were issued.

All phantom units outstanding under the LTIPs at June 30, 2011 include DERs granted to the participants by the LTIP Committee. The amounts paid with respect to LTIP DERs were $0.1 and $0.3 million during the three months and six months ended June 30, 2011, respectively. These amounts were recorded as a reduction of Partners’ capital on the Partnership’s consolidated balance sheets. No DERs were paid during the six months ended June 30, 2010.

The following table sets forth the Partnership’s LTIPs phantom unit activity for the periods indicated:

Employee Incentive Compensation Plan and Agreement

A wholly-owned subsidiary of the Partnership has an incentive plan (the “Cash Plan”), which allows for equity-indexed cash incentive awards to employees of the Partnership (the “Participants”). The Cash Plan is administered by a committee appointed by the CEO of the General Partner. Under the Cash Plan, cash bonus units may be awarded to Participants at the discretion of the committee. During 2009, the committee granted 375,000 bonus units (“Bonus Units”). A Bonus Unit entitles the employee to receive the cash equivalent of the then-fair market value of a common limited partner unit, without payment of an exercise price, upon vesting of the Bonus Unit. Bonus Units vest ratably over a three year period from the date of grant and will automatically vest upon a change of control, death, or termination without cause, each as defined in the governing document. Vesting will terminate upon termination of employment with cause. In conjunction with the approval of the 2010 LTIP, the holders of 300,000 of the then outstanding 375,000 Bonus Units agreed to exchange their Bonus Units for phantom units, during the six months ended June 30, 2010.

At June 30, 2011, the Partnership had 25,500 outstanding Bonus Units, which will all vest within the following twelve months. The Partnership recognizes compensation expense related to these awards based upon the fair value, which is re-measured each reporting period based upon the current fair value of the underlying common units. The Partnership recognized expense of $0.1 million and $0.6 million in the three and six months ended June 30, 2011, respectively, within general and administrative expense on its consolidated statements of operations. In the three and six months ended June 30, 2010, the Partnership recognized a credit of $0.3 million and $1.0 million of compensation expense, respectively, within general and administrative expense on its consolidated statements of operations, related to the re-measurement of the outstanding Bonus Units during these periods. The Partnership had $0.6 million and $0.8 million, at June 30, 2011 and December 31, 2010, respectively, included within accrued liabilities on its consolidated balance sheet with regard to these awards, which represents their fair value as of those dates.

NOTE 14 – RELATED PARTY TRANSACTIONS

The Partnership does not directly employ any persons to manage or operate its business. These functions are provided by the General Partner and employees of Atlas Energy, L.P. The General Partner does not receive a management fee in connection with its management of the Partnership apart from its interest as general partner and its right to receive incentive distributions. The Partnership reimburses the General Partner and its affiliates for compensation and benefits related to its employees who perform services for the Partnership based upon an estimate of the time spent by such persons on activities for the Partnership. Other indirect costs, such as rent for offices, are allocated to the Partnership by Atlas Energy, L.P. based on the number of its employees who devote their time to activities on the Partnership’s behalf.

The partnership agreement provides that the General Partner will determine the costs and expenses that are allocable to the Partnership in any reasonable manner determined by the General Partner at its sole discretion. These costs and expenses are limited to $1.8 million for the twelve months following the closing of the Chevron Merger (see Note 1). The Partnership reimbursed the General Partner and its affiliates $0.5 million and $0.4 million for the three months ended June 30, 2011 and 2010, respectively, and $0.9 million $0.8 million for the six months ended June 30, 2011 and 2010, respectively, for compensation and benefits related to its employees. There were no reimbursements for direct expenses incurred by the General Partner and its affiliates for the six months ended June 30, 2011 and 2010. The General Partner believes that the method utilized in allocating costs to the Partnership is reasonable.

On February 17, 2011, the Partnership completed the sale of its 49% interest in Laurel Mountain to Atlas Energy Resources for $409.5 million; including closing adjustments and net of expenses (see Note 3).

NOTE 15 – SEGMENT INFORMATION

On February 17, 2011, the Partnership sold its 49% interest in Laurel Mountain, which was reported as part of the Partnership’s previous Appalachia segment (see Note 3). On May 11, 2011, the Partnership acquired a 20% interest in WTLPG (see Note 3). As a result of these two transactions, the Partnership realigned the reportable segments into two new segments: Gathering and Processing; and Pipeline Transportation (“Pipeline”). These reportable segments reflect the way the Partnership will manage its operations going forward. The Partnership has adjusted its segment presentation from the amounts previously presented to reflect the realignment of the segments.

The Gathering and Processing segment consists of (1) the Chaney Dell, Velma and Midkiff/Benedum operations, which are comprised of natural gas gathering and processing assets servicing drilling activity in the Anadarko and Permian Basins, and which were formerly included within the previous Mid-Continent segment; (2) the natural gas gathering assets located in Tennessee, which were formerly included in the previous Appalachia segment; and (3) the revenues and gain on sale related to the Partnership’s 49% interest in Laurel Mountain, which were formerly included in the previous Appalachia segment. Gathering and Processing revenues are primarily derived from the sale of residue gas and NGLs and gathering of natural gas.

The Pipeline segment consists of the equity income generated by the newly acquired interest in WTLPG, which owns a 2,295 mile common-carrier pipeline system that transports NGLs from New Mexico and Texas to Mont Belvieu, Texas for fractionation. Pipeline revenues are primarily derived from transportation fees.

The following summarizes the Partnership’s reportable segment data for the periods indicated (in thousands):

NOTE 17 – SUBSEQUENT EVENTS

On July 8, 2011, the Partnership exercised the $100.0 million accordion feature on its revolving credit facility to increase the capacity from $350.0 million to $450.0 million. The other terms of the credit agreement remain unchanged.

On July 15, 2011, the Partnership amended an operating lease for eight natural gas compressors to include a mandatory purchase of the equipment at the end of the term of the lease, thereby converting the agreement into a capital lease upon the effective date of the amendment. The Partnership will include $11.4 million within property plant and equipment with an offsetting liability within debt on the Partnership’s consolidated balance sheets based on the minimum payments required under the lease and the Partnership’s incremental borrowing rate. Expected minimum lease payments, including the mandatory purchase of the equipment, are estimated to be as follows: 2011 - $1.0 million; 2012 - $2.4 million; 2013 - $9.1 million.

General

The following discussion provides information to assist in understanding our financial condition and results of operations. This discussion should be read in conjunction with our consolidated financial statements and related notes thereto appearing elsewhere in this report and with our Annual Report on Form 10-K for the year ended December 31, 2010.

Overview

We are a publicly-traded Delaware limited partnership formed in 1999 whose common units are listed on the New York Stock Exchange under the symbol “APL.” We are a leading provider of natural gas gathering, processing and treating services in the Anadarko and Permian Basins located in the southwestern and mid-continent regions of the United States; a provider of natural gas gathering services in the Appalachian Basin in the northeastern region of the United States; and a provider of NGL transportation services in the southwestern region of the United States.

Due to the sale of our 49% non-controlling interest in Laurel Mountain Midstream, LLC (“Laurel Mountain”), a Delaware limited liability company and our acquisition of a 20% interest in West Texas LPG Pipeline Limited Partnership (“WTLPG”) (see “–Recent Events”), we realigned the management of our business in the midstream segment of the natural gas industry into two new reportable segments: Gathering and Processing; and Pipeline Transportation.

The Gathering and Processing segment consists of (1) the Chaney Dell, Velma and Midkiff/Benedum operations, which are comprised of natural gas gathering and processing assets servicing drilling activity in the Anadarko and Permian Basins, and which were formerly included within the previous Mid-Continent segment; (2) the natural gas gathering assets located in Tennessee, which were formerly included in the previous Appalachia segment; and (3) the revenues and gain on sale related to our 49% interest in Laurel Mountain, which were formerly included in the previous Appalachia segment. Gathering and Processing revenues are primarily derived from the sale of residue gas and NGLs and gathering of natural gas.

Our Gathering and Processing operations, as of June 30, 2011, own, have interests in and operate five natural gas processing plants with aggregate capacity of approximately 520 MMCFD, which are connected to approximately 8,600 miles of active natural gas gathering systems located in Oklahoma, Kansas and Texas. These assets were formerly included in our previous Mid-Continent segment. In addition we own and operate approximately 70 miles of active natural gas gathering systems located in

Tennessee, which were formerly included in our previous Appalachia segment. Our gathering systems gather gas from wells and central delivery points and deliver to natural gas processing and treating plants, as well as third-party pipelines.

Our Pipeline Transportation operations, as of June 30, 2011, own a 20% interest in WTLPG, which was acquired on May 11, 2011 (see “–Recent Events”). WTLPG owns a 2,295 mile common-carrier pipeline system that transports NGLs from New Mexico and Texas to Mont Belvieu, Texas for fractionation. WTLPG is operated by Chevron Pipeline Company, an affiliate of Chevron, which owns the remaining 80% interest.

Recent Events

On February 17, 2011, we completed the sale to Atlas Energy Resources, LLC of our 49% non-controlling interest in Laurel Mountain for $409.5 million in cash, net of expenses and including adjustments based on certain capital contributions we made to and distributions we received from Laurel Mountain after January 1, 2011. We retained the preferred distribution rights under the limited liability company agreement of Laurel Mountain entitling APL Laurel Mountain, LLC, our wholly-owned subsidiary, to receive all payments made under a note issued to Laurel Mountain by Williams Laurel Mountain, LLC in connection with the formation of Laurel Mountain. We intend to utilize the proceeds from the sale to repay our indebtedness, to fund future capital expenditures, and for general corporate purposes.

On April 7, 2011, we purchased $7.2 million, or 3.24%, of the outstanding 8.75% Senior Notes, which represented all of the 8.75% Senior Notes validly tendered pursuant to our offer to purchase the 8.75% Senior Notes, at par, and paid $0.2 million in accrued and unpaid interest for a total payment of $7.4 million (see “–Senior Notes”). We funded the purchase from a portion of the net proceeds from the sale of our 49% non-controlling interest in Laurel Mountain.

On April 8, 2011, we redeemed all of our 8.125% Senior Notes for a total redemption of $293.7 million, including accrued interest of $7.0 million and premium of $11.2 million (see “–Senior Notes”). The redemption was funded with a portion of the net proceeds from the sale of our 49% non-controlling interest in Laurel Mountain.

On May 11, 2011, we acquired a 20% interest in WTLPG from Buckeye Partners, L.P. for $85.0 million. WTLPG owns a 2,295 mile common-carrier pipeline system that transports NGLs from New Mexico and Texas to Mont Belvieu, Texas for fractionation and is operated by Chevron Pipeline Company, an affiliate of Chevron, which owns the remaining 80% interest.

On May 27, 2011, we redeemed our 8,000 units of Class C Preferred Units for cash at the liquidation value of $1,000 per unit, or $8.0 million plus $0.2 million accrued dividends. There are no longer any Class C Preferred Units outstanding (see “–Preferred Units”).

Subsequent Events

On July 8, 2011, we exercised the $100.0 million accordion feature on our revolving credit facility to increase the capacity from $350.0 million to $450.0 million. The other terms of the credit agreement remain unchanged.

On July 15, 2011, we amended an operating lease for eight natural gas compressors to include a mandatory purchase of the equipment at the end of the term of the lease, thereby converting the agreement into a capital lease upon the effective date of the amendment. We will include $11.4 million within property plant and equipment with an offsetting liability within debt on our consolidated balance sheets based on the minimum payments required under the lease and our incremental borrowing rate.

Contractual Revenue Arrangements

Our principal revenue is generated from the gathering and sale of natural gas, NGLs and condensate. Variables that affect our revenue are:

•

the volumes of natural gas we gather and process, which in turn, depend upon the number of wells connected to our gathering systems, the amount of natural gas the wells produce, and the demand for natural gas, NGLs and condensate;

•

the price of the natural gas we gather and process and the NGLs and condensate we recover and sell, which is a function of the relevant supply and demand in the mid-continent, mid-Atlantic and northeastern areas of the United States;

•

the NGL and BTU content of the gas that is gathered and processed;

•

the contract terms with each producer; and

•

the efficiency of our gathering systems and processing plants.

Revenue consists of the sale of natural gas and NGLs and the fees earned from our gathering and processing operations. Under certain agreements, we purchase natural gas from producers and move it into receipt points on our pipeline systems and then sell the natural gas and NGLs off delivery points on our systems. Under other agreements, we gather natural gas across our systems, from receipt to delivery point, without taking title to the natural gas. Revenue associated with the physical sale of natural gas is recognized upon physical delivery of the natural gas (see “Item 1. Notes to Consolidated Financial Statements (Unaudited) –Note 2–Revenue Recognition” for further discussion of contractual revenue arrangements).

(1)	Restated to reflect amounts reclassified to discontinued operations due to our sale of the Elk City system (see “Item 1. Notes to Consolidated Financial Statements (Unaudited) –Note 4”).

Natural gas and liquids revenue for the three months ended June 30, 2011 increased primarily due to a favorable price change as a result of higher realized commodity prices combined with higher production volumes across all systems.

Volumes on the Velma system increased for the three months ended June 30, 2011 when compared to the prior year period primarily due to new production gathered on the Madill-to-Velma gas gathering pipeline. Volumes on the Chaney Dell system increased for the three months ended June 30, 2011 compared to the prior year due to the completion of an expansion into Kansas in June 2010. Midkiff/Benedum system volumes for the three months ended June 30, 2011 increased when compared to the prior year period due to increased volumes from Pioneer Natural Resources (NYSE: PXD) (“Pioneer”) as a result of their continued drilling program.

Other income (loss), net, including the impact of certain gains and losses recognized on derivatives had a favorable variance for the three months ended June 30, 2011 due primarily to $1.1 million lower net cash settlements on commodity-based derivatives. We enter into derivative instruments solely to hedge our forecasted natural gas, NGLs and condensate sales against the variability in expected future cash flows attributable to changes in market prices. See further discussion of derivatives under “Item 3: Quantitative and Qualitative Disclosures About Market Risk.”

Costs and Expenses. The following table details the costs and expenses changes between the three months ended June 30, 2011 and 2010 (in thousands):

(1)	Restated to reflect amounts reclassified to discontinued operations due to our sale of the Elk City system (see “Item 1. Notes to Consolidated Financial Statements (Unaudited) –Note 4”).

Natural gas and liquids cost of goods sold for the three months ended June 30, 2011 increased primarily due to an increase in average commodity prices and processed volumes in comparison to the prior year period, as discussed above in “Revenues.”

Plant operating expense for the three months ended June 30, 2011 increased primarily due to increased processed volumes in comparison to the prior year period, as discussed above in “Revenues.”

Transportation and compression expenses for the three months ended June 30, 2011 decreased due to lower throughput volumes on the Tennessee gathering system.

General and administrative expense, including amounts reimbursed to affiliates, increased for the three months ended June 30, 2011 primarily due to an increase in salaries and wages resulting mainly from a $2.1 million credit to bonus expense in the prior year period.

Other costs for the three months ended June 30, 2011 are associated with the acquisition of WTLPG in May 2011 (see “–Recent Events”).

Interest expense for the three months ended June 30, 2011 decreased primarily due to a $7.3 million decrease in interest expense associated with our term loan retired in the prior year; a $5.2 million decrease in interest expense associated with the 8.125% Senior Notes and a $4.3 million decrease in interest expense associated with our revolving credit facility. The lower interest expense on our term loan and revolving credit facility is primarily due to the retirement of the term loan and a reduction of the credit facility borrowings in September 2010 with proceeds from the sale of Elk City. The lower interest expense on our 8.125% Senior Notes is due to the redemption of the 8.125% Senior Notes in April 2011, with proceeds from the sale of our 49% non-controlling interest in Laurel Mountain (see “–Recent Events”).

Other income items. The following table details the changes between the three months ended June 30, 2011 and 2010 for other income items (in thousands):


	Three Months Ended June 30,
	2011			2010⁽¹⁾			Variance			Percent Change
Equity income in joint ventures	$	687		$	888		$	(201	)		(22.6	)%

Income attributable to non-controlling interests		(1,545	)		(945	)		(600	)		(63.5	)%

(1)	Restated to reflect amounts reclassified to discontinued operations due to our sale of the Elk City system (see “Item 1. Notes to Consolidated Financial Statements (Unaudited) –Note 4”).

Equity income in joint ventures for the current year period represents our ownership interest in the net income of WTLPG, which we purchased on May 11, 2011 (see “–Recent Events”). Equity income in joint ventures for the prior year period represents our ownership interest in the net income of Laurel Mountain, which we sold on February 17, 2011 (see “–Recent Events”).

Loss on asset sales and other for the three months ended June 30, 2011 includes amounts associated with the sale of our 49% interest in Laurel Mountain on February 17, 2011 (see “–Recent Events”).

Loss on early extinguishment of debt for the three months ended June 30, 2011 represents the premium paid for the redemption of the 8.125% Senior Notes and the recognition of deferred finance costs related to the redemption (see “–Recent Events”).

Income from discontinued operations, which consists of amounts associated with the Elk City system, decreased from the prior year period due to its sale in September 2010.

Income attributable to non-controlling interests increased primarily due to higher net income for the Midkiff/Benedum and Chaney Dell joint ventures, which were formed to accomplish our acquisition of control of the systems. The increase in net income of the joint ventures was principally due to higher gross margins on the sale of commodities, resulting from higher prices and volumes. The non-controlling interest expense represents Anadarko Petroleum Corporation’s interest in the net income of the Chaney Dell and Midkiff/Benedum joint ventures.

Six Months Ended June 30, 2011 Compared to Six Months Ended June 30, 2010

(1)	Restated to reflect amounts reclassified to discontinued operations due to our sale of the Elk City system (see “Item 1. Notes to Consolidated Financial Statements (Unaudited) –Note 4”).

Natural gas and liquids revenue for the six months ended June 30, 2011 increased primarily due to a favorable price change as a result of higher realized commodity prices combined with higher production volumes across all systems.

Volumes on the Velma system increased for the six months ended June 30, 2011 when compared to the prior year period primarily due to new production gathered on the Madill-to-Velma gas gathering pipeline. Volume on the Chaney Dell system increased for the six months ended June 30, 2011 compared to the prior year due to the completion of an expansion into Kansas in June 2010. Midkiff/Benedum system volumes for the six months ended June 30, 2011 increased when compared to the prior year period due to increased volumes from Pioneer as a result of their continued drilling program.

Other income (loss), net, including the impact of certain gains and losses recognized on derivatives had an unfavorable variance for the six months ended June 30, 2011 due primarily to a $19.1 million unfavorable variance in non-cash mark-to-market adjustments on commodity-based derivatives. We enter into derivative instruments solely to hedge our forecasted natural gas, NGLs and condensate sales against the variability in expected future cash flows attributable to changes in market prices. See further discussion of derivatives under “Item 3: Quantitative and Qualitative Disclosures About Market Risk.”

(1)	Restated to reflect amounts reclassified to discontinued operations due to our sale of the Elk City system (see “Item 1. Notes to Consolidated Financial Statements (Unaudited) –Note 4”).

Natural gas and liquids cost of goods sold for the six months ended June 30, 2011 increased primarily due to an increase in average commodity prices and processed volumes in comparison to the prior year period, as discussed above in “Revenues.”

Plant operating expense for the six months ended June 30, 2011 increased primarily due to increased processed volumes in comparison to the prior year period, as discussed above in “Revenues.”

Transportation and compression expenses for the six months ended June 30, 2011 decreased due to lower throughput volumes on the Tennessee gathering system.

General and administrative expense, including amounts reimbursed to affiliates, increased for the six months ended June 30, 2011 mainly due to an increase in net salaries and wages and share based compensation of $0.8 million and increased outside services of $0.7 million. The increase in the net salaries and wages and share based compensation resulted partially from $0.5 million related to accelerated vesting of phantom units and options in the current year.

Other costs for the six months ended June 30, 2011 are associated with the acquisition of WTLPG in May 2011 (see “–Recent Events”).

Interest expense for the six months ended June 30, 2011 decreased primarily due to a $14.5 million decrease in interest expense associated with our term loan retired during the prior year; a $9.0 million decrease in interest expense associated with our revolving credit facility; and a $5.2 million decrease in interest expense associated with the 8.125% Senior Notes. The lower interest expense on our term loan and revolving credit facility is primarily due to the retirement of the term loan and a reduction of the credit facility borrowings in September 2010 with proceeds from the sale of Elk City. The lower interest expense on our 8.125% Senior Notes is due to the redemption of the 8.125% Senior Notes in April 2011, with proceeds from the sale of our 49% non-controlling interest in Laurel Mountain (see “–Recent Events”).

(1)	Restated to reflect amounts reclassified to discontinued operations due to our sale of the Elk City system (see “Item 1. Notes to Consolidated Financial Statements (Unaudited) –Note 4”).

Equity income in joint ventures decreased for the six months ended June 30, 2011, primarily due to the sale of our ownership interest in Laurel Mountain on February 17, 2011, resulting in $1.9 million lower equity earnings from Laurel Mountain (see “–Recent Events”); partially offset by $0.7 million equity earnings generated in the current period from our 20% ownership interest in WTPLG, which was purchased in May 2011 (see “–Recent Events”).

Gain on asset sales and other for the six months ended June 30, 2011 includes amounts associated with the sale of our 49% interest in Laurel Mountain on February 17, 2011 (see “–Recent Events”).

Loss on early extinguishment of debt for the six months ended June 30, 2011 represents the premium paid for the redemption of the 8.125% Senior Notes and the recognition of deferred finance costs related to the redemption (see “–Recent Events”).

Income (loss) from discontinued operations, which consists of amounts associated with the Elk City system, decreased from the prior year period due to its sale in September 2010.

Liquidity and Capital Resources

General

Our primary sources of liquidity are cash generated from operations and borrowings under our revolving credit facility. Our primary cash requirements, in addition to normal operating expenses, are for debt service, capital expenditures and quarterly distributions to our common unitholders and General Partner. In general, we expect to fund:

•

cash distributions and maintenance capital expenditures through existing cash and cash flows from operating activities;

•

expansion capital expenditures and working capital deficits through the retention of cash and additional capital raising; and

•

debt principal payments through operating cash flows and refinancings as they become due, or by the issuance of additional limited partner units or asset sales.

At June 30, 2011, we had $142.5 million outstanding borrowings under our $350.0 million senior secured revolving credit facility and $1.7 million of outstanding letters of credit, which are not reflected as borrowings on our consolidated balance sheets, with $205.8 million of remaining committed capacity under the revolving credit facility, (see “–Revolving Credit Facility”). On July 8, 2011, the revolving credit facility was increased to $450.0 million (see “–Subsequent Events”). We were in compliance with the credit facility’s covenants at June 30, 2011. We had a working capital deficit of $35.2 million at June 30, 2011 compared with a $36.6 million working capital deficit at December 31, 2010. We believe that we will have sufficient liquid assets, cash from operations and borrowing capacity to meet our financial commitments, debt service obligations, contingencies and anticipated capital expenditures for at least the next twelve-month period. However, we are subject to business, operational and other risks that could adversely affect our cash flow. We may need to supplement our cash generation with proceeds from financing activities, including borrowings under our credit facility and other borrowings, the issuance of additional limited partner units and sales of our assets.

Instability in the financial markets, as a result of recession or otherwise, may cause volatility in the markets and may impact the availability of funds from those markets. This may affect our ability to raise capital and reduce the amount of cash available to fund our operations. We rely on our cash flow from operations and our revolving credit facility to execute our growth strategy and to meet our financial commitments and other short-term liquidity needs. We cannot be certain that additional capital will be available to the extent required and on acceptable terms.

Cash Flows – Six Months Ended June 30, 2011 Compared to Six Months Ended June 30, 2010

The following table details the cash flow changes between the six months ended June 30, 2011 and 2010 (in thousands):


	Six Months Ended June 30,									Percent
	2011			2010			Variance			Change
Net cash provided by (used in):
Operating activities	$	51,910		$	57,126		$	(5,216	)		(9.1	)%
Investing activities		222,562			(29,377	)		251,939			857.6	%
Financing activities		(274,470	)		(28,610	)		(245,860	)		(859.3	)%

Net change in cash and cash equivalents	$	2		$	(861	)	$	863			100.2	%

Net cash provided by operating activities for the six months ended June 30, 2011 decreased due to a $30.9 million decrease in the change in working capital and a $4.4 million decrease in cash provided by discontinued operations; offset by a $30.1 million increase in net earnings from continuing operations excluding non-cash charges. The decrease in the change in working capital is primarily due to a $41.2 million reduction in receivables during the prior year period. The increase in net earnings from continuing operations excluding non-cash charges is primarily due to increased revenues from the sale of natural gas and NGLs (see “–Results of Operations”).

Net cash provided by investing activities for the six months ended June 30, 2011 increased as a result of the net proceeds of $411.5 million received from the sale of our 49% interest in Laurel Mountain (see “–Recent Events”); partially offset by the $85.0 million paid for the acquisition of WTLPG (see “– Recent Events”) and a $72.1 million increase in capital expenditures compared to the prior year period (see further discussion of capital expenditures under “–Capital Requirements”).

Net cash used in financing activities for the six months ended June 30, 2011 increased mainly due to $293.9 million paid for the redemption of the 8.125% Senior Notes and a portion of the 8.75% Senior Notes in the current period; combined with a $42.9 million increase in distributions paid; partially offset by a $113.5 million net increase in borrowings on our revolving credit facility. The proceeds from the sale of Laurel Mountain were utilized in the redemption of the Senior Notes (see “–Recent Events”).

Capital Requirements

Our operations require continual investment to upgrade or enhance existing operations and to ensure compliance with safety, operational, and environmental regulations. Our capital requirements consist primarily of:

•

maintenance capital expenditures to maintain equipment reliability and safety and to address environmental regulations; and

•

expansion capital expenditures to acquire complementary assets and to expand the capacity of our existing operations.

The following table summarizes maintenance and expansion capital expenditures, excluding amounts paid for acquisitions, for the periods presented (in thousands):


	Three Months Ended June 30,				Six Months Ended June 30,
	2011		2010⁽¹⁾		2011		2010⁽¹⁾
Maintenance capital expenditures	$	5,211	$	3,008	$	8,471	$	3,883
Expansion capital expenditures		68,425		10,053		83,498		16,855

Total	$	73,636	$	13,061	$	91,969	$	20,738

(1)	Restated to reflect amounts reclassified to discontinued operations due to our sale of the Elk City system (see “Item 1. Notes to Consolidated Financial Statements (Unaudited) –Note 4”).

Expansion capital expenditures increased for the three and six months ended June 30, 2011 primarily due to processing facility expansions, compressor upgrades and pipeline projects. The increase in maintenance capital expenditures for the three and six months ended June 30, 2011 when compared with the prior year period was due to fluctuations in the timing of scheduled maintenance activity. As of June 30, 2011, we have approved additional expenditures of approximately $210.6 million on processing facility expansions; pipeline extensions; and compressor station upgrades. We expect to fund these projects through operating cash flow and borrowings under our existing revolving credit facility.

Partnership Distributions

Our partnership agreement requires that we distribute 100% of available cash to our common unitholders and our General Partner within 45 days following the end of each calendar quarter in accordance with their respective percentage interests. Available cash consists generally of all of our cash receipts, less cash disbursements and net additions to reserves, including any reserves required under debt instruments for future principal and interest payments.

Our General Partner is granted discretion by our partnership agreement to establish, maintain and adjust reserves for future operating expenses, debt service, maintenance capital expenditures and distributions for the next four quarters. These reserves are not restricted by magnitude, but only by type of future cash requirements with which they can be associated. When our General Partner determines our quarterly distributions, it considers current and expected reserve needs along with current and expected cash flows to identify the appropriate sustainable distribution level.

Available cash is initially distributed 98% to our common limited partners and 2% to our General Partner. These distribution percentages are modified to provide for incentive distributions to be paid to our General Partner if quarterly distributions to common limited partners exceed specified targets. Incentive distributions are generally defined as all cash distributions paid to our General Partner that are in excess of 2% of the aggregate amount of cash being distributed. Our General Partner, holder of all of our incentive distribution rights, has agreed to allocate up to $3.75 million of its incentive distribution rights per quarter back to us after the General Partner receives the initial $7.0 million of incentive distribution rights per quarter. No incentive distributions were declared during the six months ended June 30, 2011 and 2010.

Off Balance Sheet Arrangements

As of June 30, 2011, our off balance sheet arrangements include our letters of credit, issued under the provisions of our revolving credit facility, totaling $1.7 million. These are in place to support various performance obligations as required by (i) statutes within the regulatory jurisdictions where we operate, (ii) surety and (iii) counterparty support.

We also have certain long-term unconditional purchase obligations and commitments, primarily take-or-pay agreements. These agreements provide transportation services to be used in the ordinary course of our operations.

Preferred Units

On June 30, 2010, we sold 8,000 newly-created 12% Cumulative Class C Preferred Units of limited partner interest (the “Class C Preferred Units”) to Atlas Energy, Inc. for cash consideration of $1,000 per Class C Preferred Unit, for total proceeds of $8.0 million.

The Class C Preferred Units received distributions of 12% per annum, paid quarterly on the same date as the distribution payment date for our common units. The record date for the determination of holders entitled to receive distributions was the same as the record date for determination of common unit holders entitled to receive quarterly distributions. We had the right to redeem some or all of the Class C Preferred Units for an amount equal to the face value of the Class C Preferred Units being redeemed plus all accrued but unpaid dividends.

On May 27, 2011, we redeemed the 8,000 Class C Preferred units for cash, at the liquidation value of $1,000 per unit, or $8.0 million, plus $0.2 million, representing the accrued dividends on the 8,000 Class C Preferred Units prior to our redemption. There are no Class C Preferred Units outstanding at June 30, 2011.

Revolving Credit Facility

At June 30, 2011, we had a $350.0 million senior secured revolving credit facility with a syndicate of banks, which matures in December 2015. On July 8, 2011, the revolving credit facility was increased to $450.0 million (see “–Subsequent Events”). Borrowings under the revolving credit facility

bear interest, at our option, at either (i) the higher of (a) the prime rate, (b) the federal funds rate plus 0.50% or (c) three-month LIBOR plus 1.0%, or (ii) the LIBOR rate for the applicable period (each plus the applicable margin). The weighted average interest rate for borrowings on the revolving credit facility, at June 30, 2011, was 3.2%. Up to $50.0 million of the revolving credit facility may be utilized for letters of credit, of which $1.7 million was outstanding at June 30, 2011. These outstanding letter of credit amounts were not reflected as borrowings on our consolidated balance sheets.

Borrowings under the revolving credit facility are secured by a lien on and security interest in all of our property and that of our subsidiaries, except for the assets owned by the Chaney Dell and Midkiff/Benedum joint ventures. Borrowings are also secured by the guaranty of each of our consolidated subsidiaries other than the joint venture companies. The revolving credit facility contains customary covenants, including covenants to maintain specified financial ratios, restrictions on our ability to incur additional indebtedness; make certain acquisitions, loans or investments; make distribution payments to our unitholders if an event of default exists; or enter into a merger or sale of assets, including the sale or transfer of interests in our subsidiaries. We are also unable to borrow under our revolving credit facility to pay distributions of available cash to unitholders because such borrowings would not constitute “working capital borrowings” pursuant to our partnership agreement.

The events which constitute an event of default for our revolving credit facility include payment defaults, breaches of representations or covenants contained in the credit agreement, adverse judgments against us in excess of a specified amount, and a change of control of our General Partner. As of June 30, 2011, we were in compliance with all covenants under the revolving credit facility.

Senior Notes

At June 30, 2011, we had $215.8 million principal amount outstanding of 8.75% senior unsecured notes due on June 15, 2018 (“8.75% Senior Notes”). Interest on the 8.75% Senior Notes is payable semi-annually in arrears on June 15 and December 15. The 8.75% Senior Notes are redeemable at any time after June 15, 2013, at certain redemption prices, together with accrued and unpaid interest to the date of redemption. The 8.75% Senior Notes are subject to repurchase by us at a price equal to 101% of their principal amount, plus accrued and unpaid interest, upon a change of control or upon certain asset sales if we do not reinvest the net proceeds within 360 days. The 8.75% Senior Notes are junior in right of payment to our secured debt, including our obligations under our revolving credit facility.

On April 7, 2011, we redeemed $7.2 million of the 8.75% Senior Notes, which were tendered upon our offer to purchase the 8.75% Senior Notes, at par. The sale of our 49% non-controlling interest in Laurel Mountain on February 17, 2011 constituted an “Asset Sale” pursuant to the terms of the indenture of the 8.75% Senior Notes. As a result of the Asset Sale, we offered to purchase any and all of the 8.75% Senior Notes.

The indenture governing the 8.75% Senior Notes contains covenants, including limitations of our ability to: incur certain liens; engage in sale/leaseback transactions; incur additional indebtedness; declare or pay distributions if an event of default has occurred; redeem, repurchase or retire equity interests or subordinated indebtedness; make certain investments; or merge, consolidate or sell substantially all of our assets. We were in compliance with these covenants as of June 30, 2011.

On April 8, 2011, we redeemed all of the 8.125% senior unsecured notes due on December 15, 2015 (“8.125% Senior Notes”). The redemption price was determined in accordance with the indenture for the 8.125% Senior Notes, plus accrued and unpaid interest thereon to the redemption date. We paid $293.7 million to redeem the $275.5 million principal plus $11.2 million premium and $7.0 million accrued interest. There are no 8.125% Senior Notes outstanding at June 30, 2011.

Critical Accounting Policies and Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires making estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of actual revenue and expenses during the reporting period. Although we base our estimates on historical experience and various other assumptions we believe to be reasonable under the circumstances, actual results may differ from the estimates on which our financial statements are prepared at any given point of time. Changes in these estimates could materially affect our financial position, results of operations or cash flows. Significant items that are subject to such estimates and assumptions include revenue and expense accruals, depreciation and amortization, asset impairment, fair value of derivative instruments, the probability of forecasted transactions and the allocation of purchase price to the fair value of assets acquired. A discussion of our significant accounting policies we have adopted and followed in the preparation of our consolidated financial statements is included within our Annual Report on Form 10-K for the year ended December 31, 2010, and there have been no material changes to these policies through June 30, 2011.

ITEM 3.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The primary objective of the following information is to provide forward-looking quantitative and qualitative information about our potential exposure to market risks. The term “market risk” refers to the risk of loss arising from adverse changes in interest rates and oil and natural gas prices. The disclosures are not meant to be precise indicators of expected future losses, but rather indicators of reasonable possible losses. This forward-looking information provides indicators of how we view and manage our ongoing market risk exposures. All of our market risk sensitive instruments were entered into for purposes other than trading.

General

All of our assets and liabilities are denominated in U.S. dollars, and as a result, we do not have exposure to currency exchange risks.

We are exposed to various market risks, principally fluctuating interest rates and changes in commodity prices. These risks can impact our results of operations, cash flows and financial position. We manage these risks through regular operating and financing activities and periodic use of derivative instruments. The following analysis presents the effect on our results of operations, cash flows and financial position as if the hypothetical changes in market risk factors occurred on June 30, 2011. Only the potential impact of hypothetical assumptions is analyzed. The analysis does not consider other possible effects that could impact our business.

Current market conditions elevate our concern over counterparty risks and may adversely affect the ability of these counterparties to fulfill their obligations to us, if any. The counterparties to our commodity-based derivatives are banking institutions, or their affiliates, currently participating in our revolving credit facility. The creditworthiness of our counterparties is constantly monitored, and we are not aware of any inability on the part of our counterparties to perform under our contracts.

Interest Rate Risk. At June 30, 2011, we had a $350.0 million senior secured revolving credit facility with $142.5 million outstanding borrowings and no interest rate derivative contracts. Borrowings under the revolving credit facility bear interest, at our option, at either (i) the higher of (a) the prime rate, (b) the federal funds rate plus 0.50% or (c) three-month LIBOR plus 1.0%, or (ii) the LIBOR rate for the applicable period (each plus the applicable margin). The weighted average interest rate for the revolving credit facility borrowings was 3.2% at June 30, 2011. Based upon the outstanding borrowings on the senior secured revolving credit facility and holding all other variables constant, a 100 basis-point, or 1%, change in interest rates would change our annual interest expense by approximately $1.4 million.

Commodity Price Risk. We are exposed to commodity prices as a result of being paid for certain services in the form of natural gas, NGLs and condensate rather than cash. For gathering services, we receive fees or commodities from the producers to bring the raw natural gas from the wellhead to the processing plant. For processing services, we either receive fees or commodities as payment for these services, based on the type of contractual agreement. We use a number of different derivative instruments in connection with our commodity price risk management activities. We enter into financial swap and option instruments to hedge our forecasted natural gas, NGLs and condensate sales against the variability in expected future cash flows attributable to changes in market prices. Swap instruments are contractual agreements between counterparties to exchange obligations of money as the underlying natural gas, NGLs and condensate are sold. Under swap agreements, we receive a fixed price and remit a floating price based on certain indices for the relevant contract period. Commodity-based option instruments are contractual agreements that grant the right to receive the difference between a fixed price and a floating price based on certain indices for the relevant contract period, if the floating price is lower than the fixed price. See “Item 1. Notes to Consolidated Financial Statements (Unaudited) –Note 9” for further discussion of our derivative instruments. Average estimated market prices for NGLs, natural gas and condensate, based upon twelve-month forward price curves as of July 5, 2011, are $1.31 per gallon, $4.61 per million BTU and $98.97 per barrel, respectively. A 10% change in these prices would change our forecasted gross margin for the twelve-month period ended June 30, 2012 by approximately $15.0 million.

ITEM 4.

CONTROLS AND PROCEDURES

We maintain disclosure controls and procedures designed to ensure information required to be disclosed in our Securities Exchange Act of 1934 reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and such information is accumulated and communicated to our management, including our General Partner’s Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, our management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and our management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Under the supervision of our General Partner’s Chief Executive Officer and Chief Financial Officer and with the participation of our disclosure committee appointed by such officers, we have carried out an evaluation of the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report. Based upon that evaluation, our General Partner’s Chief Executive Officer and Chief Financial Officer concluded that as of June 30, 2011, our disclosure controls and procedures were effective at the reasonable assurance level.

There have been no changes in our internal control over financial reporting during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
