NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1. ORGANIZATION AND DESCRIPTION OF BUSINESS

Description of Business—Eagle Rock Energy Partners, L.P. ("Eagle Rock Energy" or the "Partnership") is a growth-oriented limited partnership engaged in (i) the business of gathering, compressing, treating, processing, transporting, marketing and trading natural gas; fractionating, transporting and marketing natural gas liquids ("NGLs"); and crude oil and condensate logistics and marketing (the “Midstream Business”); and (ii) the business of developing and producing interests in oil and natural gas properties (the “Upstream Business”). The Partnership's midstream assets are strategically located in four productive, mature natural gas producing regions: the Texas Panhandle; East Texas/Louisiana; South Texas; and the Gulf of Mexico. The Partnership's natural gas pipelines gather natural gas from designated points near producing wells and transport these volumes to third-party pipelines, the Partnership's gas processing plants, utilities and industrial consumers. Natural gas transported to the Partnership's gas processing plants, either in the Partnership's pipelines or third party pipelines, is treated to remove contaminants and conditioned or processed into marketable natural gas and NGLs. The Partnership reports its Midstream Business results through three segments: the Texas Panhandle Segment; the East Texas and Other Midstream Segment; and the Marketing and Trading Segment.  The Partnership's upstream assets are characterized by long-lived, high-working interest properties with extensive production histories and development opportunities. Its upstream assets are located primarily in South Alabama (where it also operates the associated gathering and processing assets), Texas, Oklahoma, Mississippi and Arkansas. The Partnership reports its Upstream Business through one segment.

The general partner of Eagle Rock Energy is Eagle Rock Energy GP, L.P., and the general partner of Eagle Rock Energy GP, L.P. is Eagle Rock Energy G&P, LLC, both of which are wholly-owned subsidiaries of the Partnership.

NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation and Principles of Consolidation—The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP"). These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements presented in the Partnership's Annual Report on Form 10-K for the year ended December 31, 2012. In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all appropriate adjustments, all of which are normally recurring adjustments unless otherwise noted, considered necessary to present fairly the financial position of the Partnership and its consolidated subsidiaries and the results of operations and cash flows for the respective periods. Operating results for the three and six months endedJune 30, 2013 are not necessarily indicative of the results that may be expected for the full year ending December 31, 2013.

Eagle Rock Energy is the owner of non-operating undivided interests in certain gas processing plants and gas gathering systems. Eagle Rock Energy owns these interests as tenants-in-common with the majority owner-operator of the facilities. Accordingly, Eagle Rock Energy includes its pro-rata share of assets, liabilities, revenues and expenses related to these assets in its financial statements. All intercompany accounts and transactions are eliminated in the unaudited condensed consolidated financial statements.

The Partnership has provided a discussion of significant accounting policies in its Annual Report on Form 10-K for the year ended December 31, 2012. Certain items from that discussion are repeated or updated below as necessary to assist in the understanding of these financial statements.

Use of Estimates—The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reported period. Significant estimates are required for proved oil and natural gas reserves, which can affect the carrying value of oil and natural gas properties. The Partnership evaluates its estimates and assumptions on a regular basis. The Partnership bases its estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ from those estimates and such differences could be material.

Inventory—Inventory is stated at the lower of cost or market, with cost being determined using the average cost method. At June 30, 2013 and December 31, 2012, the Partnership had $0.6 million and $0.8 million, respectively, of crude oil finished goods inventory, which is recorded as part of Other Current Assets within the unaudited condensed consolidated balance sheet.

EAGLE ROCK ENERGY PARTNERS, L.P.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Impairment of Long-Lived Assets—Management evaluates whether the carrying value of non-oil and natural gas long-lived assets has been impaired when circumstances indicate the carrying value of those assets may not be recoverable. This evaluation is based on undiscounted cash flow projections. The carrying amount is not recoverable if it exceeds the undiscounted sum of cash flows expected to result from the use and eventual disposition of the assets. Management considers various factors when determining if these assets should be evaluated for impairment, including, but not limited to:

• significant adverse changes in legal factors or in the business climate;

• a current-period operating or cash flow loss combined with a history of operating or cash flow losses or a projection or forecast which demonstrates continuing losses associated with the use of a long-lived asset;

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

• significant adverse changes in the extent or manner in which an asset is used or in its physical condition;

• a significant change in the market value of an asset; or

• a current expectation that, more likely than not, an asset will be sold or otherwise disposed of before the end of its estimated useful life.

For its oil and natural gas long-lived assets, accounted for utilizing the successful efforts method, the Partnership reviews its proved properties at the depletion unit when management determines that events or circumstances indicate that the recorded carrying value of the properties may not be recoverable. Such events include a negative revision to the proved reserves estimates, unfavorable projections of future prices, the timing of future production and estimates of future costs to produce the oil and natural gas. Unproved properties (both individually significant and insignificant) are assessed periodically within specific geographic areas and, if necessary, impairments are charged to expense.

If the carrying value is not recoverable on an undiscounted basis, the impairment loss is measured as the excess of the asset's carrying value over its fair value. Management assesses the fair value of long-lived assets using commonly accepted techniques, and may use more than one method, including, but not limited to, recent third party comparable sales, internally developed discounted cash flow analysis and analysis from outside advisors. Significant changes in market conditions resulting from events such as the condition of an asset or a change in management's intent to utilize the asset would generally require management to reassess the cash flows related to the long-lived assets.  

See Notes 4 and 6 for further discussion on impairment charges.

Revenue Recognition—The Partnership's primary types of sales and service activities reported as operating revenue include:

• sales of natural gas, NGLs, crude oil, condensate and sulfur; 

• natural gas gathering, processing and transportation, from which the Partnership generates revenues primarily through the compression, gathering, treating, processing and transportation of natural gas; and 

• NGL transportation from which the Partnership generates revenues from transportation fees.

Revenues associated with sales of natural gas, NGLs, crude oil, condensate and sulfur are recognized when title passes to the customer, which is when the risk of ownership passes to the customer and physical delivery occurs. Revenues associated with transportation and processing fees are recognized in the period when the services are provided.

For gathering and processing services, the Partnership either receives fees or commodities from natural gas producers under various types of contracts including percentage-of-proceeds, fixed recovery and percent-of-index arrangements. The Partnership also recognizes fee-based service revenues for services such as transportation, compression and processing.

The Partnership's Upstream Segment recognizes natural gas revenues based on the amount of natural gas sold to purchasers. The volumes of natural gas sold may differ from the volumes to which the Partnership is entitled based on its interests in the properties. Differences between volumes sold and volumes based on entitlements create natural gas imbalances. Material imbalances are reflected as adjustments to reported natural gas reserves and future cash flows.  For the Upstream Segment, as of , the Partnership had long-term imbalance payables totaling $0.3 million and $0.6 million as of June 30, 2013 and December 31, 2012, respectively.

Transportation and Exchange Imbalances—In the course of transporting natural gas and NGLs for others, the Partnership may receive for redelivery different quantities of natural gas or NGLs than the quantities actually delivered. These transactions result in transportation and exchange imbalance receivables or payables which are recovered or repaid through the

7

EAGLE ROCK ENERGY PARTNERS, L.P.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

receipt or delivery of natural gas or NGLs in future periods, if not subject to cash out provisions. Imbalance receivables are included in accounts receivable and imbalance payables are included in accounts payable on the unaudited condensed consolidated balance sheets and marked-to-market using current market prices in effect for the reporting period of the outstanding imbalances. For the Midstream Business, as of June 30, 2013, the Partnership had imbalance receivables totaling $1.2 million and imbalance payables totaling $2.6 million. For the Midstream Business, as of December 31, 2012, the Partnership had imbalance receivables totaling $0.2 million and imbalance payables totaling $2.1 million. Changes in market value and the settlement of any such imbalance at a price greater than or less than the recorded imbalance results in either an upward or downward adjustment, as appropriate, to the cost of natural gas sold.

Derivatives—Authoritative guidance establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities. It requires an entity to recognize all derivatives as either assets or liabilities in the statement of financial position and measure those instruments at fair value. The guidance provides that normal purchase and sale contracts, when appropriately designated, are not subject to the guidance. Normal purchases and sales are contracts which provide for the purchase or sale of something, other than a financial instrument or derivative instrument, that will be delivered in quantities expected to be used or sold by the reporting entity over a reasonable period in the normal course of business. The Partnership's forward natural gas and crude oil purchase and sales contracts are designated as normal purchases and normal sales, with the exception of certain contracts with it's natural gas trading and marketing business. The Partnership uses financial instruments such as swaps, collars and other derivatives to mitigate the risks to cash flows resulting from changes in commodity prices and interest rates. The Partnership recognizes these financial instruments on its unaudited condensed consolidated balance sheet at the instrument's fair value with changes in fair value reflected in the unaudited condensed consolidated statement of operations, as the Partnership has not designated any of these derivative instruments as hedges. The cash flows from derivatives are reported as cash flows from operating activities unless the derivative contract is deemed to contain a financing element. Derivatives deemed to contain a financing element are reported as a financing activity in the unaudited condensed consolidated statement of cash flows. See Note 10 for a description of the Partnership's risk management activities.

Other Reclassifications—Certain prior period financial statement balances have been reclassified to conform to the current year presentation. These reclassifications had no effect on the recorded net income.

NOTE 3. NEW ACCOUNTING PRONOUNCEMENTS

In December 2011, the Financial Standards Accounting Board ("FASB") issued new guidance related to disclosure requirements about the nature of an entity's rights of set-off and related arrangements associated with its financial instruments and derivative instruments. The new disclosures are designed to make financial statements that are prepared under U.S. GAAP more comparable to those prepared under International Financial Reporting Standards ("IFRS"). To better facilitate comparison between financial statements prepared under U.S. GAAP and IFRS, the new disclosures will give financial statement users information about both gross and net exposures. The disclosure requirements were effective for the Partnership on January 1, 2013, and did not have a material impact on the Partnership's financial statements for the six months ended June 30, 2013. See Notes 10 and 11 for the disclosures related to the Partnership's rights of set-off and the gross and net exposure related to its derivative instruments.

________________________________

(a) During the three and six months endedJune 30, 2013, the Partnership incurred impairment charges in its Upstream Business related to certain proved property primarily in the Permian region due to lower commodity prices and continued high operating costs.

(b) During the three and six months endedJune 30, 2012, the Partnership incurred impairment charges in its Upstream Business related to certain unproved property leaseholds expected to expire in 2013.

(c) During the six months endedJune 30, 2012, the Partnership incurred impairment charges in its Midstream Business related to certain plants and pipelines in its East Texas and Other Segment due to (i) reduced throughput volumes as its producer customers curtailed their drilling activity in response to the continued depressed natural gas price environment during the first three months of 2012 and (ii) the loss of significant gathering contracts on its Panola system during the three months endedJune 30, 2012.

NOTE 5. ASSET RETIREMENT OBLIGATIONS

The Partnership recognizes asset retirement obligations associated with the retirement of tangible long-lived assets that result from the acquisition, construction and development of the assets. The Partnership records the fair value of a liability for an asset retirement obligation in the period in which it is incurred and a corresponding increase in the carrying amount of the

related long-lived asset. The Partnership makes estimates of property abandonment costs that, in some cases, will not be incurred until a substantial number of years in the future. Such cost estimates could be subject to significant revisions in subsequent years due to changes in regulatory requirements, technological advances and other factors that may be difficult to predict. Although uncertainty about the timing and/or method of settlement may exist and may be conditional upon a future event, the obligation to perform the asset retirement activity is unconditional. Accordingly, the Partnership is required to recognize a liability for the fair value of a conditional asset retirement obligation upon initial recognition if the fair value of the liability can be reasonably estimated. The fair value of additions to the asset retirement obligations is estimated using valuation techniques that convert future cash flows to a single discounted amount. Significant inputs to the valuation include estimates of (i) remediation costs, (ii) remaining lives, (iii) future inflation factors and (iv) a credit-adjusted risk free interest rate.

A reconciliation of the Partnership's liability for asset retirement obligations is as follows:

_____________________________________

(a) As of June 30, 2013 and December 31, 2012, $9.9 million and $3.9 million, respectively, were included within accrued liabilities in the Unaudited Condensed Consolidated Balance Sheets.

During the six months endedJune 30, 2013, the Partnership made revisions of $6.6 million to increase certain asset retirement obligations due to changes in the estimate of the costs to remediate.

NOTE 6. INTANGIBLE ASSETS

Intangible assets consist of rights-of-way and easements and acquired customer contracts, which the Partnership amortizes over the term of the agreement or estimated useful life. The amortization period for the Partnership's rights-of-way and easements is 20 years. The amortization periods for contracts range from 5 to 20 years.  Intangible assets consisted of the following:

The Partnership currently pays an annual fee of 0.50% on the unused commitment under the revolving credit facility. As of June 30, 2013, the Partnership had approximately $25.3 million of outstanding letters of credit and approximately $164.4 million of availability under its revolving credit facility, based on its borrowing base of $803 million. The revolving credit facility matures on June 22, 2016.

On July 23, 2013, the Partnership and its lenders amended the revolving credit facility to allow for a temporary step-up in the Total Leverage Ratio and the Senior Secured Leverage Ratio, as defined therein, through the third quarter of 2014 and the third quarter of 2013, respectively. The amendment also extends the period of time the Partnership is subject to the Senior Secured Leverage Ratio from September 30, 2013 to September 30, 2014. The amendment was effective as of June 30, 2013, and adjusts the Total Leverage Ratio and Senior Secured Leverage Ratio covenants as follows:

NOTE 10. RISK MANAGEMENT ACTIVITIES

Interest Rate Swap Derivative Instruments

To mitigate its interest rate risk, the Partnership has entered into interest rate swaps. These swaps convert a portion of the Partnership's obligations under it's variable-rate revolving credit facility into a fixed-rate obligation. The purpose of entering into these swaps is to eliminate interest rate variability by converting LIBOR-based variable-rate payments to fixed-rate payments. Amounts received or paid under these swaps were recorded as reductions or increases in interest expense.

For accounting purposes, the Partnership has not designated any of its interest rate derivative instruments as hedges; instead it marks these derivative contracts to fair value (see Note 11).  Changes in fair values of the interest rate derivative instruments are recorded as an adjustment to the mark-to-market gains (losses) on risk management transactions within other income (expense).

The following table sets forth certain information regarding the Partnership's interest rate swaps as of June 30, 2013:

Effective Date	Expiration Date	Notional Amount		Fixed Rate
6/22/2011	6/22/2015	$	250,000,000	2.950	%

Commodity Derivative Instruments

The prices of crude oil, natural gas and NGLs are subject to fluctuations in response to changes in supply, demand, market uncertainty and a variety of additional factors which are beyond the Partnership's control.  These risks can cause significant changes in the Partnership's cash flows and affect its ability to achieve its distribution objectives and comply with the covenants of its revolving credit facility.  In order to manage the risks associated with changes in the future prices of crude oil, natural gas and NGLs on its forecasted equity production, the Partnership engages in risk management activities that take the form of commodity derivative instruments.  Historically, the Partnership has hedged a substantial portion of its expected production in an attempt to meaningfully reduce its future cash flow volatility.  The Partnership generally limits its hedging levels to less than its total expected future production. While hedging at this level of production does not attempt to eliminate all of the volatility in the Partnership's cash flows, it allows the Partnership to mitigate the risk of situations where a modest loss of production would not put it in an over-hedged position.  At times, the Partnership's strategy may involve entering into hedges with strike prices above current future prices or resetting existing hedges to higher price levels in order to meet its cash flow objectives or to stay in compliance with the covenants under its revolving credit facility.  In addition, the Partnership may also terminate or unwind hedges or portions of hedges when the expected future volumes do not support the level of hedges.  Expected future production for its Upstream Business is derived from the proved reserves, adjusted for price-dependent expenses and revenue deductions.  For the Midstream Business, expected future production is based on the expected production from wells currently flowing to the Partnership's processing plants, plus additional volumes the Partnership expects to receive from future drilling activity by its producer customer base.  The Partnership's expectations for its Midstream Business volumes associated with future drilling are based on information it receives from its producer customer base and historical observations. The Partnership applies the appropriate contract terms to these projections to determine its expected future equity share of the commodities.

The Partnership uses fixed-price swaps, costless collars and put options to achieve its hedging objectives. Historically, the Partnership has hedged its expected future commodity volumes either with derivatives of the same commodity ("direct hedges") or with derivatives of another commodity which the Partnership expects will correlate well with the underlying commodity ("proxy hedges").  For example, the Partnership will often hedge the changes in future NGL prices using crude oil hedges because NGL prices have been highly correlated to crude oil prices and hedging NGLs directly is usually less attractive due to the relative illiquidity in the NGL forward market.  The Partnership may use natural gas hedges to hedge a portion of its expected future ethane production because forward prices for ethane are often heavily discounted from its current prices.  Also, natural gas prices provide support for ethane prices because in many processing plants ethane can be recombined with the residue gas stream and sold as natural gas.  When the Partnership uses proxy hedges, it converts the expected volumes of the underlying commodity to equivalent volumes of the hedged commodity.  In the case of NGLs hedged with crude oil derivatives, these conversions are based on the historical relationship of the prices of the two commodities and management's judgment regarding future price relationships of the commodities.  In the case where ethane is hedged with natural gas derivatives, the conversion is based on the thermal content of ethane. In recent quarters, the correlation of price changes in crude oil and NGLs

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

has weakened relative to longer-term averages as NGL prices have fallen while crude index prices have risen. This dynamic has negatively impacted our hedging objectives.

For accounting purposes, the Partnership has not designated any of its commodity derivative instruments as hedges; instead it marks these derivative contracts to fair value (see Note 11).  Changes in fair values of the commodity derivative instruments are recorded as an adjustment to the mark-to-market gains (losses) on risk management transactions within revenue.

By using derivative instruments to economically hedge exposure to changes in commodity prices, the Partnership exposes itself to counterparty credit risk. Historically, the Partnership's counterparties have all been participants or affiliates of participants within its revolving credit facility, which is secured by substantially all of the assets of the Partnership. Therefore, the Partnership is not currently required to post any collateral, nor does it require collateral from its counterparties. The Partnership minimizes the credit risk in derivative instruments by limiting exposure to any single counterparty and monitoring the creditworthiness of its counterparties on an ongoing basis. In addition, the Partnership's derivative contracts for certain counterparties are subject to counterparty netting agreements governing such derivatives, and when possible, the Partnership nets the open positions of each counterparty. See Note 11 for the impact to the Partnership's unaudited condensed consolidated balance sheets of the netting of these derivative contracts.

Commodity Derivative Instruments - Marketing & Trading

The Partnership conducts natural gas marketing and trading activities. The Partnership engages in activities intended to capitalize on favorable price differentials between various receipt and delivery locations. The Partnership's activities are governed by its risk policy.

As part of its natural gas marketing and trading activities, the Partnership enters into both financial derivatives and physical contracts. These financial derivatives, primarily basis swaps, are transacted: (i) to economically hedge subscribed capacity exposed to market rate fluctuations; and (ii) to mitigate the price risk related to other purchase and sales of natural gas. By entering into a basis swap, one pricing index is exchanged for another, effectively locking in the margin between the natural gas purchase and sale by removing index spread risk on the combined physical and financial transaction.

A commodity-related derivative contract may be designated as a "normal" purchase or sale if the commodity is to be physically received or delivered for use or sale in the normal course of business. If designated as "normal," the derivative contract is accounted for under the accrual method of accounting (not marked-to-market) with no balance sheet or income statement recognition of the contract until settlement. Commodity-related contracts that do not qualify for the normal designation are accounted for as derivatives and are marked-to-market each period.

Through the Partnership's natural gas marketing activity, the Partnership has credit exposure to additional counterparties. The Partnership minimizes the credit risk associated with natural gas marketing by limiting its exposure to any single counterparty and monitoring the creditworthiness of its counterparties on an ongoing basis. In addition, the Partnership's natural gas purchase and sale contracts for certain counterparties, are subject to counterparty netting agreements governing settlement under such natural gas purchase and sales contracts, and when possible, the Partnership nets the open positions of each counterparty. See Note 11 for the impact to the Partnership's unaudited condensed consolidated balance sheets of the netting of these contracts.

NOTE 11. FAIR VALUE OF FINANCIAL INSTRUMENTS

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). The Partnership utilizes market data or assumptions that market participants would use in pricing the asset or liability, including assumptions about risk inherent in the inputs to the valuation technique. The authoritative guidance establishes a fair value hierarchy that prioritizes the inputs used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements).

The three levels of the fair value hierarchy are as follows:

16

EAGLE ROCK ENERGY PARTNERS, L.P.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Level 1 – Quoted prices are available in active markets for identical assets and liabilities as of the reporting date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide information on an ongoing basis.

Level 2 – Pricing inputs are other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable as of the reporting date. Level 2 includes those financial instruments that are valued using models or other valuation methodologies. These models are primarily industry-standard models that consider various assumptions, including quoted forward prices for commodities, time value, volatility factors and current market and contractual prices for the underlying instruments, as well as other relevant economic measures. Substantially all of these assumptions are observable in the market place throughout the full term of the instrument, can be derived from observable data or are supported by observable levels at which transactions are executed in the marketplace.

Level 3 – Pricing inputs include significant inputs that are generally less observable from objective sources. These inputs may be used with internally developed methodologies that result in management's best estimate of fair value.

As of June 30, 2013, the Partnership recorded its interest rate swaps and commodity derivative instruments (see Note 10), which includes crude oil, natural gas and NGLs, at fair value. The Partnership reviews the classification of the inputs at the end of each period and classified the inputs to measure the fair value of its interest rate swaps, crude oil derivatives, NGL derivatives and natural gas derivatives as Level 2. 

The following tables disclose the fair value of the Partnership's derivative instruments as of June 30, 2013 and December 31, 2012:

Fair Value of Assets and Liabilities Measured on a Non-recurring Basis

For periods in which impairment charges have been incurred, the Partnership is required to write down the value of the impaired asset to its fair value. See Note 4 for a further discussion of the impairment charges recorded during the three and six months endedJune 30, 2013. The following table discloses the fair value of the Partnership's assets measured at fair value on a nonrecurring basis during the six months ended June 30, 2013:

	June 30, 2013		Level 1		Level 2		Level 3		Total Losses
	($ in thousands)
Proved properties	$	1,546	$	—	$	—	$	1,546	$	1,839

The Partnership calculated the fair value of the impaired assets using a discounted cash flow analysis to determine the excess of the asset's carrying value over its fair value. Significant inputs to the valuation of fair value of the proved properties included estimates of (i) future estimated cash flows, including revenue, expenses and capital expenditures, (ii) estimated timing of cash flows, (iii) estimated forward commodity prices, adjusted for estimate location differentials and (iv) a discount rate reflective of our cost of capital.

The carrying amount of cash equivalents is believed to approximate their fair values because of the short maturities of these instruments. The fair value of accounts receivable and accounts payable are not materially different from their carrying amounts because of the short-term nature of these instruments.

As of June 30, 2013, the outstanding debt associated with the Partnership's revolving credit facility bore interest at a floating rate; as such, the Partnership believes that the carrying value of this debt approximates its fair value. The Partnership's 8.375% Senior Notes bear interest at a fixed rate; based on the market price of the Senior Notes as of June 30, 2013, the Partnership estimates that the fair value of the Senior Notes was $561.0 million compared to a carrying value of $544.9 million. Fair value of the Senior Notes was estimated based on prices quoted from third-party financial institutions, which are characteristic of Level 2 fair value measurement inputs.

NOTE 12. COMMITMENTS AND CONTINGENCIES

Litigation—The Partnership is subject to lawsuits which arise from time to time in the ordinary course of business, such as the interpretation and application of contractual terms related to the calculation of payment for liquids and natural gas

18

EAGLE ROCK ENERGY PARTNERS, L.P.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

proceeds. The Partnership had no accruals as of June 30, 2013 or December 31, 2012 related to legal matters, and current lawsuits are not expected to have a material adverse effect on our financial position, results of operations or cash flows. The Partnership has been indemnified up to a certain dollar amount for two lawsuits. If there ultimately is a finding against the Partnership in these two indemnified cases, the Partnership would expect to make a claim for indemnification up to the contractual limits.

Insurance—The Partnership covers its operations and assets with insurance which management believes is consistent with that in force for other companies engaged in similar commercial operations with similar type properties.  This insurance includes: (1) commercial general liability insurance covering liabilities to third parties for bodily injury, property damage and pollution arising out of the Partnership's operations; (2) workers’ compensation liability coverage for employees to required statutory limits; (3) automobile liability insurance covering liability to third parties for bodily injury and property damage arising out of the operation of all owned, hired and non-owned vehicles by its employees on company business; (4) property insurance covering the replacement cost of all owned real and personal property, including coverage for losses due to boiler and machinery breakdown, earthquake, flood and consequent business interruption/extra expense; (5) control of well/operator's extra expense insurance for operated and non-operated wells in the Upstream Segment; and (6) corporate liability insurance, including coverage for directors and officers and employment practices liabilities.  In addition, the Partnership maintains excess liability insurance providing limits in excess of the established primary limits for commercial general liability and automobile liability insurance.

Environmental—The operation of pipelines, plants and other facilities for gathering, transporting, processing, treating, or storing natural gas, NGLs and other products is subject to stringent and complex laws and regulations pertaining to health, safety and the environment. As an owner or operator of these facilities, the Partnership must comply with United States laws and regulations at the federal, state and local levels that relate to air and water quality, hazardous and solid waste management and disposal and other environmental matters. The cost of planning, designing, constructing and operating pipelines, plants, and other facilities must incorporate compliance with environmental laws and regulations and safety standards. Failure to comply with these laws and regulations may trigger a variety of administrative, civil and potentially criminal enforcement measures, including citizen suits, which can include the assessment of monetary penalties, the imposition of remedial requirements and the issuance of injunctions or restrictions on operation. Management believes that, based on currently known information, compliance with these laws and regulations will not have a material adverse effect on the Partnership's combined results of operations, financial position or cash flows. At June 30, 2013 and December 31, 2012, the Partnership had accrued approximately $2.9 million and $2.8 million for environmental matters, respectively.

Retained Revenue Interest—Certain assets of the Partnership's Upstream Segment are subject to retained revenue interests.  These interests were established under purchase and sale agreements that were executed by the Partnership's predecessors in title.  The terms of these agreements entitle the owners of the retained revenue interests to a portion of the revenues received from the sale of the hydrocarbons above specified base oil and natural gas prices.  These retained revenue interests do not represent a real property interest in the hydrocarbons.  The Partnership's reported revenues are reduced to account for the retained revenue interests on a monthly basis.

The retained revenue interests affect the Partnership's interest in the Big Escambia Creek, Flomaton and Fanny Church fields in Escambia County, Alabama. With respect to the Partnership's Flomaton and Fanny Church fields, these retained revenue interests are in effect for any calendar year in which the Partnership surpasses certain average net production rates. The Partnership did not surpass such rates in 2012 and does not anticipate doing so in 2013. With respect to the Partnership's Big Escambia Creek field, the retained revenue interest commenced in 2010 and continues through the end of 2019.

Other Commitments—The Partnership utilizes assets under operating leases for its corporate office, certain rights-of-way and facilities locations, vehicles and in several areas of its operations. Rental expense, including leases with no continuing commitment, amounted to approximately $2.3 million, $4.4 million, $2.0 million and $4.4 million for the three and six months endedJune 30, 2013 and 2012, respectively. Rental expense for leases with escalation clauses is recognized on a straight-line basis over the initial lease term.

NOTE 13. SEGMENTS

Based on the Partnership’s approach to managing its assets, the Partnership believes its operations consist of three segments in its Midstream Business, one Upstream segment and one Corporate segment:

(i)Midstream—Texas Panhandle Segment: gathering, compressing, treating, processing and transporting natural gas; fractionating, transporting and marketing NGLs;

19

EAGLE ROCK ENERGY PARTNERS, L.P.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(ii)    Midstream—East Texas and Other Midstream Segment: gathering, compressing, processing and treating natural gas and marketing of natural gas, NGLs and condensate in South Texas, East Texas, Louisiana, Gulf of Mexico and inland waters of Texas;

(iii)        Midstream—Marketing and Trading Segment: crude oil and condensate logistics and marketing in the Texas Panhandle and Alabama; and natural gas marketing and trading;

(iv)    Upstream Segment: crude oil, condensate, natural gas, NGLs and sulfur production from operated and non-operated wells; and

(v)    Corporate and Other Segment: risk management, intersegment eliminations and other corporate activities such as general and administrative expenses.

The Partnership's chief operating decision maker ("CODM") currently reviews its operations using these segments. The CODM evaluates segment performance based on segment operating income or loss from continuing operations. Summarized financial information concerning the Partnership's reportable segments is shown in the following tables:

NOTE 14. INCOME TAXES

Provision for Income Taxes -The Partnership's provision for income taxes relates to (i) state taxes for the Partnership and (ii) federal taxes for Eagle Rock Energy Acquisition Co., Inc. and Eagle Rock Energy Acquisition Co. II, Inc. and their wholly-owned subsidiary corporations, Eagle Rock Upstream Development Company, Inc. and Eagle Rock Upstream Development Company II, Inc., all of which are subject to federal income taxes.

Effective Rate - The effective rate for the six months endedJune 30, 2013 was 10.4% compared to (1.5)% for the six months endedJune 30, 2012. Due to the fact that the effective rate is a ratio of total tax expense compared to pre-tax book net income, the change is due primarily to book and tax temporary differences for the six months endedJune 30, 2013 as compared to the six months endedJune 30, 2012.

NOTE 15. EQUITY-BASED COMPENSATION

Eagle Rock Energy G&P, LLC, the general partner of the general partner of the Partnership, has a long-term incentive plan (as amended, the "LTIP"), for its employees, directors and consultants who provide services to the Partnership and its subsidiaries and affiliates. The LTIP provides for the issuance of an aggregate of up to 7,000,000 common units to be granted either as options, restricted units or phantom units, of which, as of June 30, 2013, a total of 674,069 common units remained available for issuance. Grants under the LTIP are made at the discretion of the board and to date have only been made in the

21

EAGLE ROCK ENERGY PARTNERS, L.P.

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

form of restricted units. Distributions declared and paid on outstanding restricted units, where such restricted units are eligible to receive distributions, are paid directly to the holders of the restricted units. No options or phantom units have been issued to date.

Grants of restricted units eligible to receive distributions are valued at the market price as of the date issued, while grants of restricted units not eligible to receive distributions are valued at the market price as of the date issued less the present value of the expected distribution stream over the vesting period using the risk-free interest rate. The awards generally vest over three years on the basis of one-third of the award each year. The Partnership recognizes compensation expense on a straight-line basis over the requisite service period for the restricted unit grants. During the restriction period, distributions associated with the granted awards are distributed to the awardees.

A summary of the changes in outstanding restricted common units for the six months endedJune 30, 2013 is provided below:

	Number of Restricted Units		Weighted Average Fair Value
Outstanding at December 31, 2012	2,608,035		$	9.38
Granted	1,579,005		$	9.28
Vested	(481,478	)	$	9.44
Forfeited	(157,053	)	$	9.79
Outstanding at June 30, 2013	3,548,509		$	9.31

For the three and six months endedJune 30, 2013 and 2012, non-cash compensation expense of approximately $3.5 million, $6.2 million, $2.8 million and $5.0 million, respectively, was recorded related to the granted restricted units as general and administrative expense on the unaudited condensed consolidated statements of operations.

As of June 30, 2013, unrecognized compensation costs related to the outstanding restricted units under the LTIP totaled approximately $25.0 million. The remaining expense is to be recognized over a weighted average of 1.98 years.

In connection with the vesting of certain restricted units during the three months endedJune 30, 2013, the Partnership cancelled 114,812 of the newly-vested common units in satisfaction of $1.0 million of employee tax liability paid by the Partnership. Pursuant to the terms of the LTIP, these cancelled units are available for future grants under the LTIP.

NOTE 16. EARNINGS PER UNIT

Basic earnings per unit is computed by dividing the net income (loss) by the weighted average number of units outstanding during a period. To determine net income (loss) allocated to each class of ownership (common and restricted common units), the Partnership first allocates net income (loss) in accordance with the amount of distributions made for the quarter by each class, if any. The remaining net income (loss) is allocated to each class in proportion to the class weighted average number of units outstanding for a period, as compared to the weighted average number of units for all classes for the period.

As of June 30, 2013 and 2012, the Partnership had unvested restricted common units outstanding, which are considered dilutive securities. These units are considered in the diluted weighted average common units outstanding number in periods of net income. In periods of net losses, these units are excluded from the diluted weighted average common units outstanding number.

The Partnership had warrants outstanding through May 15, 2012. Any warrants outstanding during a reporting period were considered to be dilutive securities. These outstanding warrants were considered in the diluted weighted average common units outstanding number in periods of net income, except in cases where the exercise price of the outstanding warrant was greater than the average market price of the common units for such periods. In periods of net losses, the outstanding warrants were excluded from the diluted weighted average common units outstanding.

The majority of the restricted units granted under the LTIP, as discussed in Note 15, contain non-forfeitable rights to the distributions declared by the Partnership and therefore meet the definition of participating securities. Participating securities are required to be included in the computation of earnings per unit pursuant to the two-class method. Restricted units granted in

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

2013 to certain senior executives and members of the board of directors are not eligible to receive the distributions declared by the Partnership and therefore do not meet the definition of participating securities.

The following table presents the Partnership's calculation of basic and diluted units outstanding for the periods indicated:

	Three Months Ended June 30,		Six Months Ended June 30,
	2013	2012	2013	2012
	(in thousands)
Weighted average units outstanding during period:
Common units - Basic	155,269	131,905	150,860	130,034
Effect of Dilutive Securities:
Warrants	—	366	—	960
Restricted Units (non-participating securities)	285	—	—	—
Restricted Units (participating securities)	1,156	1,168	—	1,107
Common units - Diluted	156,710	133,439	150,860	132,101

For the three months endedJune 30, 2013 and the three and six months endedJune 30, 2012, the Partnership determined that it is more dilutive to apply the two-class method versus the treasury stock method in calculating dilutive earnings per unit. Thus, these unvested restricted common units are included in the computation of the diluted weighted average common unit outstanding calculation, but the denominator in the computation of diluted earnings per unit only includes the basic weighted average common units outstanding, the weighted average warrants and restricted units (non-participating securities) outstanding.

NOTE 17. SUBSIDIARY GUARANTORS

The Partnership has issued registered debt securities guaranteed by its subsidiaries.  As of June 30, 2013, all guarantors were wholly-owned or available to be pledged and such guarantees were joint and several and full and unconditional.  Although the guarantees of our subsidiary guarantors are considered full and unconditional, the guarantees are subject to certain customary release provisions. Such guarantees may be released in the following customary circumstances:

• in connection with any sale or other disposition of all or substantially all of the properties or assets of that guarantor (including by way of merger or consolidation) to a person that is not (either before or after giving effect to such transaction) an issuer or a restricted subsidiary of us;

• in connection with any sale or other disposition of capital stock of that guarantor to a person that is not (either before or after giving effect to such transaction) an issuer or a restricted subsidiary of us, such that, the guarantor ceases to be a restricted subsidiary of us as a result of the sale or other disposition;

• if we designate any restricted subsidiary that is a guarantor to be an unrestricted subsidiary in accordance with the applicable provisions of the indenture;

• upon legal defeasance or satisfaction and discharge of the indenture;

• upon the liquidation or dissolution of such guarantor provided no default or event of default has occurred that is continuing;

• at such time as such guarantor ceases to guarantee any other indebtedness of either of the issuers or any guarantor; or

• upon such guarantor consolidating with, merging into or transferring all of its properties or assets to us or another guarantor, and as a result of, or in connection with, such transaction such guarantor dissolving or otherwise ceasing to exist.

In accordance with Rule 3-10 of SEC Regulation S-X, the Partnership has prepared Unaudited Condensed Consolidating Financial Statements as supplemental information.  The following unaudited condensed consolidating balance sheets at June 30, 2013 and December 31, 2012, and unaudited condensed consolidating statements of operations for the three and six months endedJune 30, 2013 and 2012, and unaudited condensed consolidating statements of cash flows for the six

NOTE 18. SUBSEQUENT EVENTS

Successful Startup of Wheeler Plant

On July 8, 2013, the Partnership announced the successful startup of its 60 MMcf/d cryogenic processing facility

in Wheeler County, Texas (the "Wheeler Plant"). Eagle Rock also constructed other intra-system pipeline enhancements in the immediate area to further facilitate product gathering, transportation and marketing to and from the Wheeler Plant. The supporting infrastructure and plant site were designed to accommodate one or more additional expansions. The construction of the facilities, associated gathering and pipelines cost approximately $65 million.

Amended Credit Facility

On July 23, 2013, the Partnership announced that the Partnership and its lending group amended the Partnership's existing senior secured credit facility to allow for a temporary step-up in the Total Leverage Ratio and the Senior Secured Leverage Ratio, as defined in the credit facility, through the third quarter of 2014 and the third quarter of 2013, respectively. The amendment also extends the period of time the Partnership is subject to the Senior Secured Leverage Ratio from September 30, 2013 to September 30, 2014. The amendment is effective as of June 30, 2013. See Note 7 for a description of the amendment to the senior secured credit facility.

OVERVIEW

The following discussion and analysis of financial condition and results of operations should be read in conjunction with our unaudited condensed consolidated financial statements, and the notes thereto, appearing elsewhere in this report, as well as our Annual Report on Form 10-K for the year ended December 31, 2012 filed with the Securities and Exchange Commission. For a description of oil and natural gas terms, see our Annual Report on Form 10-K for the year ended December 31, 2012.

We are a domestically-focused, growth-oriented, publicly-traded Delaware limited partnership engaged in the following two businesses:

• Midstream Business—gathering, compressing, treating, processing, transporting, marketing and trading natural gas; fractionating, transporting and marketing NGLs; and crude oil and condensate logistics and marketing; and

• Upstream Business—developing and producing oil and natural gas property interests.

We conduct, evaluate and report on our Midstream Business within three segments—the Texas Panhandle Segment, the East Texas and Other Midstream Segment and the Marketing and Trading Segment. On October 1, 2012, we completed our acquisition of BP America Production Company's ("BP") Texas Panhandle midstream assets (the "Panhandle Acquisition"), as discussed further below. Our Texas Panhandle Segment consists of gathering and processing assets in the Texas Panhandle. Our East Texas and Other Midstream Segment consists of gathering and processing assets in East Texas/Northern Louisiana, South Texas, Southern Louisiana, the Gulf of Mexico and Galveston Bay. Our Marketing and Trading Segment consists of crude oil and condensate logistics and marketing in the Texas Panhandle and Alabama and natural gas marketing and trading.  During the three and six months endedJune 30, 2013, our Midstream Business had operating income of $8.4 million and $16.0 million, respectively, compared to operating losses of $12.1 million and $46.2 million during the three and six months endedJune 30, 2012, respectively.  

We conduct, evaluate and report on our Upstream Business as one segment, which includes operated and non-operated wells located in the Mid-Continent (which includes areas in Oklahoma, Arkansas, and the Texas Panhandle); Permian (which includes areas in West Texas); East Texas / South Texas / Mississippi; and Southern Alabama (which also includes two treating facilities and one natural gas processing plant and related gathering systems).  During the three and six months endedJune 30, 2013, our Upstream Business had operating income of $12.9 million and $25.1 million, respectively, compared to operating income of $9.1 million and $29.3 million during the three and six months endedJune 30, 2012, respectively.  

Our final reporting segment is our Corporate and Other Segment, which is where we account for our risk management activity (excluding any risk management activity associated with our natural gas marketing and trading activities), intersegment eliminations and our general and administrative expenses.  During the three and six months endedJune 30, 2013, our Corporate and Other Segment had an operating income of $10.6 million and an operating loss of $26.8 million, respectively, compared to operating income of $76.9 million and $52.2 million during the three and six months endedJune 30, 2012, respectively.  Results reflected a net gain, realized and unrealized, on our commodity derivatives of $30.5 million and $12.6 million during the three and six months endedJune 30, 2013, respectively, compared to a net gain, realized and unrealized, on our commodity derivatives of $96.0 million and $87.4 million during the three and six months endedJune 30, 2012, respectively.  See "-Results of Operations - Corporate and Other Segment" for a further discussion of the impact of our commodity derivatives.

Acquisitions

On October 1, 2012, we completed the Panhandle acquisition, including the Sunray and Hemphill processing plants and associated 2,500 mile gathering system, for $230.6 million, which included certain closing adjustments.

In addition, on October 1, 2012, we entered into a 20-year, fixed-fee Gas Gathering and Processing Agreement with BP under which we will gather and process BP's natural gas production from the existing wells connected to the newly-acquired Panhandle System. Furthermore, BP has committed itself to us under the same agreement, and committed its farmees to us under substantially the same terms, with respect to all future natural gas production from new wells drilled within an initial two-year period from closing, subject to mutually-agreed extensions, and within a two-mile radius of any portion of our gathering system serving such BP connected wells.

31

Impairment

During the three and six months endedJune 30, 2013, we recorded an impairment charge of $1.8 million in our Upstream Business related to certain proved properties primarily in the Permian region due to lower commodity prices and continued high operating costs. During the three and six months endedJune 30, 2013, we recorded no impairment charges in our Midstream Businesses. During the three and six months endedJune 30, 2012, we recorded an impairment charge of $20.6 million and $66.1 million, respectively, in our Midstream Business related to certain plants and pipelines in our East Texas and Other Segment due to (i) reduced throughput volumes as its producer customers curtailed their drilling activity in response to the continued depressed natural gas price environment during the first three months of 2012 and (ii) the loss of significant gathering contracts on the Panola system during the three months endedJune 30, 2012. During the three and six months endedJune 30, 2012, we recorded an impairment charge of $0.8 million in our Upstream Business related to certain unproved property leaseholds expected to expire in 2013.

Pursuant to accounting principles generally accepted in the United States of America ("GAAP"), our impairment analysis does not take into account the value of our commodity derivative instruments, which generally increase as the estimates of future prices decline.  Further declines in commodity prices and other factors could result in additional impairment charges and changes to the fair value of our derivative instruments.

Subsequent Events

Successful Startup of Wheeler Plant

On July 8, 2013, we announced the successful startup of our 60 MMcf/d cryogenic processing facility

in Wheeler County, Texas (the "Wheeler Plant"). We also constructed other intra-system pipeline enhancements in the immediate area to further facilitate product gathering, transportation and marketing to and from the Wheeler Plant. The supporting infrastructure and plant site were designed to accommodate one or more additional expansions. The construction of the facilities, associated gathering and pipelines cost approximately $65 million.

Amended Credit Facility

On July 23, 2013, we announced that we and our lending group amended our existing senior secured credit facility to allow for a temporary step-up in the Total Leverage Ratio and the Senior Secured Leverage Ratio, as defined in the credit facility, through the third quarter of 2014, respectively. The amendment also extends the period of time the Partnership is subject to the Senior Secured Leverage Ratio from September 30, 2013 to September 30, 2014. The amendment is effective as of June 30, 2013. See Note 7 for a description of the amendment to the senior secured credit facility.

(a) Gathering volumes (Mcf/d) and natural gas positions (MMbtu/d) are calculated by taking the total volume and then dividing by the number of days in the respective period.

(b) Includes the cost of gathering, compression, processing and treating fees of $0.7 million, $1.0 million, $0.7 million and $0.7 million, respectively, for the three and six months ended June 30, 2013 and 2012.

(c) Excludes the impact of adjustments related to prior periods, including true-ups of estimates.

(d) The three and six months endedJune 30, 2012 included the receipt of an insurance payment of $2.9 million for business interruption related to the downtime to our Cargray plant caused by the severe winter weather in 2011.

Revenues and Cost of Natural Gas, NGLs, Condensate and Helium. For the three and six months endedJune 30, 2013, revenues minus cost of natural gas, NGLs, condensate and helium for our Texas Panhandle Segment operations totaled $41.7 million and $77.5 million, respectively, compared to $30.6 million and $62.6 million for the three and six months endedJune 30, 2012, respectively. The addition of volumes from the Panhandle Acquisition, which closed on October 1, 2012, positively impacted the Texas Panhandle Segment's revenues minus cost of natural gas, NGLs, condensate and helium relative to the corresponding prior year period by $14.2 million and $25.6 million during the three and six months endedJune 30, 2013, respectively. This increase resulting from the Panhandle Acquisition was partially offset by the following: (i) lower condensate and NGL prices, (ii) the harsh winter storms in the Texas Panhandle in early January and late February 2013, which resulted in lower volumes and lower-than-normal NGL recovery rates and (iii) adjustments related to amounts recorded during the three months ended December 31, 2012. During the three and six months endedJune 30, 2013, we received new information related to the assets acquired in the Panhandle Acquisition, which were operated by BP during the three months ended December 31, 2012. We were informed that the cost of natural gas, NGLs and condensate on the assets was higher than previously

34

communicated. Due to these adjustments, our results for the three and six months endedJune 30, 2013 were negatively impacted by $0.8 million and $2.0 million, respectively.

Our NGL equity volumes were lower in part due to our decision to reject ethane during the three and six months endedJune 30, 2013. Our election to reject ethane is an economic decision based on our contract portfolio and the price spread between ethane and natural gas.  This decision also has a positive impact on our natural gas volumes as the ethane remains unprocessed and sold as natural gas.

Our Texas Panhandle Segment lies within 14 counties in Texas and consists of our East Panhandle System and our West Panhandle System. The combination of our contract mix and the high NGL content of the natural gas gathered in the West Panhandle System provides us with a high level of equity NGL and condensate production; however, the limited drilling activity on this system is not sufficient to offset the natural declines of the existing wells. As such, any declines in gathered volumes from the West Panhandle System must be offset with increases in gathered volumes from other systems on a greater than one-to-one basis in order to maintain our total equity NGL and condensate production. We have seen continued drilling activity in the East Panhandle System by our producer customers and expect drilling activity and the resulting volumes to continue during the remainder of 2013.

Operating Expenses. Operating expenses, including taxes other than income, for the three and six months endedJune 30, 2013, increased $9.6 million and $14.5 million, respectively, as compared to the three and six months endedJune 30, 2012. The increase was primarily driven by $8.9 million and $13.9 million, respectively, of costs related to the operation of the assets acquired in the Panhandle Acquisition for the three and six months endedJune 30, 2013. Excluding the acquisition, operating expenses increased primarily due to higher chemical costs and increased labor and related expenses, partially offset by repair costs related to the incident at our Phoenix processing facility in 2012.

Depreciation and Amortization. Depreciation and amortization expenses for the three and six months endedJune 30, 2013 increased $4.1 million and $8.5 million, respectively, from the three and six months endedJune 30, 2012. The increase was due to increased depreciation expense primarily associated with the new Woodall Plant, the assets acquired in the Panhandle Acquisition and other capital projects placed into service during the period.

Capital Expenditures. Capital expenditures for the three and six months endedJune 30, 2013, decreased by $17.3 million and $32.4 million, respectively, compared to the three and six months endedJune 30, 2012. The decrease was primarily driven by spending related to the construction of our Woodall Plant in 2012, partially offset by spending related to construction of our Wheeler Plant in 2013.

On July 8, 2013, we announced the successful startup of previously announced 60 MMcf/d high-efficiency cryogenic processing plant in Wheeler County, Texas, in the heart of the Granite Wash play. With the completion of the Wheeler Plant, we now have in excess of 500 MMcf/d of high-efficiency cryogenic processing capacity serving the Granite Wash play. The construction of the Wheeler Plant and associated gathering and compression is expected to cost approximately $65 million, of which $59.1 million had been spent through June 30, 2013.

_________________________

(a) Gathering volumes (Mcf/d) and natural gas positions (MMbtu/d) are calculated by taking the total volume and then dividing by the number of days in the respective period.

(b) Includes the cost of gathering, compression, processing and treating fees of $0.7 million, $1.2 million, $1.3 million and $2.8 million, respectively, for the three and six months ended June 30, 2013 and 2012.

(c) Excludes the impact of adjustments related to prior periods, including true-ups of estimates.

Revenues and Cost of Natural Gas, NGLs and Condensate. For the three and six months endedJune 30, 2013, revenues minus cost of natural gas and NGLs for our East Texas and Other Midstream Segment totaled $11.0 million and $22.1 million, respectively, compared to $12.0 million and $23.8 million for the three and six months endedJune 30, 2012, respectively. During the three and six months endedJune 30, 2013 and 2012, we recorded revenues associated with indemnity payments of $1.9 million, $4.0 million, $0.7 million and $0.7 million, respectively. We receive indemnity payments under certain of our gathering contracts when delivered volumes fail to meet certain thresholds. These amounts are included within gathering and treating services revenue. Excluding these indemnity payments, revenues minus cost of natural gas, NGLs and condensate for the three and six months endedJune 30, 2013 and 2012, would have been $9.1 million, $18.1 million, $11.3 million and $23.1 million, respectively. The decrease, excluding indemnity payments, for the three and six months endedJune 30, 2013 compared to the three and six months endedJune 30, 2012, is primarily due to a decrease in gathering and equity volumes and lower condensate and NGL prices.

The gathering, NGL and condensate volumes for the three and six months endedJune 30, 2013, decreased as compared to the three and six months endedJune 30, 2012, due in part to the impact of Hurricane Isaac in August 2012, which caused significant damage to the Yscloskey Plant in Louisiana, in which we have a non-operated ownership interest. The owners of the Yscloskey Plant elected to shut down the facility following Hurricane Isaac. We estimate this negatively impacted gathering volumes by approximately 52 MMcf/d and NGL volumes by approximately 14,400 Bbls for the six months ended June 30, 2013. In addition, our volumes declined due to the loss of customers on our Panola system, which we estimate

36

negatively impacted gathering volumes by approximately 4 MMcf/d, NGL volumes by approximately 18,300 Bbls and condensate volumes by approximately 4,100 Bbls for the six months ended June 30, 2013. Also contributing to the decrease in gathering, NGL and condensate volumes were natural declines in the production of the existing wells and reduced drilling activity in dry-gas formations related to a decline in natural gas prices.

Operating Expenses. Operating expenses for the three and six months endedJune 30, 2013, decreased $0.8 million and $1.1 million, respectively, compared to the three and six months endedJune 30, 2012, primarily due to the lower operating expenses at Yscloskey and Panola.

Impairment. No impairment charges were recorded during the three and six months endedJune 30, 2013. We recorded impairment charges of $20.6 million and $66.1 million during the three and six months endedJune 30, 2012, respectively, on certain assets due to (i) reduced throughput volumes as our producer customers curtailed their drilling activity in response to the continued depressed natural gas price environment during the first three months of 2012 and (ii) the loss of significant gathering contracts on our Panola system during the three months endedJune 30, 2012.

Depreciation and Amortization. Depreciation and amortization expenses for the three and six months endedJune 30, 2013, decreased $1.7 million and $3.8 million, respectively, compared to the three and six months endedJune 30, 2012. The decrease was a result of the impairment charges recorded during 2012.

Capital Expenditures. Capital expenditures for the three and six months endedJune 30, 2013 increased $0.1 million and decreased $0.8 million, respectively, compared to the three and six months endedJune 30, 2012. The decrease for the six months endedJune 30, 2013, was due to capital expenditures incurred in 2012 related to the Indian Springs plant.

Our Marketing and Trading Segment is comprised of our crude and condensate marketing operations and our natural gas marketing and trading activities. Our crude and condensate operations consist of developing and implementing marketing uplift strategies surrounding crude oil and condensate production in Alabama and in the Texas Panhandle. Through our natural gas marketing and trading activities, we seek to capitalize on opportunities that naturally extend from our upstream and midstream assets. Where in the past, we generally sold to wholesale buyers at the tailgates and wellheads of our assets, now we hold transportation agreements and move our product to many locations and types of buyers. This strategy diversifies our credit and performance risk and allows us to capitalize on daily, monthly and seasonal changes in market conditions.

As part of our natural gas marketing and trading activities, we enter into both financial derivatives and physical contracts. Our financial derivatives, primarily basis swaps, are transacted, among other things: (i) to economically hedge subscribed capacity exposed to market rate fluctuations; and (ii) to mitigate the price risk related to other purchase and sales of

37

natural gas. By entering into a basis swap, one pricing index is exchanged for another, effectively locking in the margin between the natural gas purchase and sale by removing index spread risk on the combined physical and financial transaction.

A commodity-related derivative contract may be designated as a "normal" purchase or sale if the commodity is to be physically received or delivered for use or sale in the normal course of business. If designated as "normal," the derivative contract is accounted for under the accrual method of accounting (not marked-to-market) with no balance sheet or income statement recognition of the contract until settlement. Commodity-related contracts that do not qualify for the normal designation are accounted for as derivatives and are marked-to-market each period.

For the three and six months endedJune 30, 2013 and 2012, revenues minus cost of oil and condensate totaled $1.7 million, $3.4 million, $0.7 million and $2.3 million, respectively. The second quarter and year-to-date increases were due to increased natural gas marketing and trading activity. Revenues for the three and six months endedJune 30, 2013, include an unrealized mark-to-market gain of $0.2 million and a loss of $0.1 million, respectively, and a loss of $0.5 million and $0.3 million for the three and six months endedJune 30, 2012, respectively, related to the financial derivatives and physical contracts.

Revenues. For the three and six months endedJune 30, 2013, Upstream Segment revenues increased by $4.1 million and decreased by $5.8 million, respectively, as compared to the three and six months endedJune 30, 2012.  The increase in revenues for the three months endedJune 30, 2013 compared to the three months endedJune 30, 2012 was due to higher realized oil and natural gas prices and higher oil, NGL and sulfur volumes, partially offset by lower natural gas volumes and lower realized NGL and sulfur prices.

The decrease in revenues for the six months endedJune 30, 2013 compared to the six months endedJune 30, 2012 was due to the lower realized oil, NGL and sulfur prices and lower oil and natural gas volumes, partially offset by higher realized natural gas prices and higher NGL and sulfur volumes. Volumes during the six months ended June 30, 2013 were negatively impacted by suspended operations at our Flomaton separation and treating facility, increased fuel consumption at our Big Escambia Creek treating and processing facility, production delays associated with certain wells' extended drilling time in the Mid-Continent, an unsuccessful development well due to mechanical issues in the Mid-Continent and less than expected volumes from our Mid-Continent and Permian recompletion projects.

On February 7, 2013, we suspended operations at our Flomaton treating facility in Escambia County, Alabama due to the failure of certain plant equipment and inlet volumes that were insufficient to operate the facility's sulfur recovery unit. To increase inlet volumes of the field to operate the treating facility we attempted to restore production from two wells connected to the facility, but these operations were unsuccessful. We resumed facility operations on April 18, 2013, after repairing the equipment and increasing inlet volumes by diverting production from a nearby operated well; however, on May 24, 2013, we again suspended operations due to equipment failure at the treating facility. We estimate that during the six months ended June 30, 2013 we lost revenues of approximately $1.2 million and incurred increased facility expenses of $0.2 million. During the first three months of 2013 we incurred increased operating expenses of approximately $2.4 million related to the production restoration attempts. On July 31, 2013, we received approval from the required percentage of owners of the Big Escambia Creek and Flomaton plants to resume operations by re-routing gas from the Flomaton facility to our Big Escambia Creek facility for treating and processing, while continuing to stabilize and sell the Flomaton field condensate at the Flomaton facility.

In March 2012, we completed a scheduled turnaround of the Flomaton facility which took approximately twelve days. We estimate the lost revenue due to the downtime was approximately $0.5 million and the turnaround expense was approximately $0.6 million for the six months endedJune 30, 2012.

In March 2013, we booked an adjustment related to 2011 revenues for certain of our wells in East Texas that are processed at the third-party owned Eustace plant. These adjustments were made by the third-party plant operator and decreased previously reported revenues by approximately $0.8 million.

On December 20, 2012, we sold our Barnett Shale properties located in Denton and Tarrant Counties, Texas. During the six months endedJune 30, 2012, the properties produced an average of 5.9 MMcfe/d with revenues of $1.8 million and operating expenses of $2.0 million.

Operating Expenses. Operating expenses, including severance and ad valorem taxes, decreased $0.9 million and $1.6 million for the three and six months endedJune 30, 2013, respectively, as compared to the three and six months endedJune 30, 2012.  The decrease was primarily due to the sale of our Barnett Shale properties, lower severance taxes resulting from decreased sales and from a refund received from the state of Oklahoma for taxes paid in prior years. These items were offset by higher workover costs related to the two attempts to restore production to the Flomaton facility and to higher post-production costs.

Depletion, Depreciation and Amortization. Depletion, depreciation and amortization expense increased by $0.1 million and decreased by $1.2 million for the three and six months endedJune 30, 2013, respectively, as compared to the same period in the prior year.  The decrease for the six months ended June 30, 2013 was primarily a result of the sale of our Barnett Shale properties and impairment charges recorded during 2012.

Impairment.  During the three and six months endedJune 30, 2013, we incurred impairment charges of $1.8 million related to certain proved properties in the Permian region due to lower commodity prices and continued high operating costs. During the three and six months endedJune 30, 2012, we incurred impairment charges of $0.8 million related to certain unproved property leasehold that is expected to expire in 2013.

Capital Expenditures.  Capital expenditures decreased by $10.4 million and $3.6 million for the three and six months endedJune 30, 2013, respectively, as compared to the three and six months endedJune 30, 2012, primarily due to reduced drilling activity offset by higher than expected drilling costs.  During the six months ended June 30, 2013, two of the

39

development wells we drilled and completed cost more than we expected due to hole stability problems, and we were unsuccessful drilling another development well due to mechanical problems.

On July 19, 2012, one of our operated wells in Wayne County, Mississippi experienced an uncontrolled flow event during a well workover operation. We have Control of Well insurance for this incident up to $20 million. We estimate the cost of the incident and the subsequent attempts to bring the well on-line were over $29.1 million. As of June 30, 2013, we had received $16.0 million of reimbursement for this incident and had a receivable of $4.0 million related to expected additional reimbursements; on July 25, 2013, we received the remaining $4.0 million. We have classified the costs above the $20 million recoverable under our insurance policy as capital expenditures.

During the three months endedJune 30, 2013, we drilled and completed five gross operated wells and participated in nine gross non-operated wells in the Mid-Continent region. Additionally, during the three months ended June 30, 2013, we conducted eleven capital workovers and six recompletions across our operations, two of which were unsuccessful.

Revenues. Our Corporate and Other Segment's revenue consists of our intersegment eliminations and our commodity derivative activity (excluding any risk management activity associated with our natural gas marketing and trading activity). Our commodity derivative activity impacts our Corporate and Other Segment revenues through: (i) the unrealized, non-cash, mark-to-market of our commodity derivatives scheduled to settle in future periods; and (ii) the realized gains or losses on our commodity derivatives settled in the indicated period. Our unrealized commodity gains and losses reflect the change in the mark-to-market value of our derivative position from the beginning of a period to the end.  In general, the change in the mark-to-market value of our derivative position may be due to several factors including the settlement of derivative instruments during the period, the addition of new derivative positions during the period, changes in the forward curves of the underlying commodities from the beginning to the end of the period, changes in interest rates used in the mark-to-market calculations from the beginning to the end of the period and the passage of time during the period.  

During the three and six months endedJune 30, 2013, unrealized gains in our commodity derivative portfolio decreased by $57.2 million and $70.3 million, respectively, as compared to the three and six months endedJune 30, 2012, due to increases in the natural gas, NGL and crude oil forward curves. 

40

During the three and six months endedJune 30, 2013, realized gains in our commodity derivatives decreased by $8.3 million and $4.5 million, respectively, compared to realized commodity derivative gains during the three and six months endedJune 30, 2012. The decrease in the realized gains for the three and six months endedJune 30, 2013, as compared to the same period in the prior year, was due to higher natural gas index prices, partially offset by lower crude oil and NGL index prices, in relation to the strike prices of our settled contracts, as compared to the same period in the prior year. In addition, the decrease in realized gains is due to the higher level of direct NGL product contracts that settled during the three and six months endedJune 30, 2012, as compared to the same period in 2013.

Given the uncertainty surrounding future commodity prices, and the general inability to predict future commodity prices as they relate to the strike prices at which we have hedged our exposure, it is difficult to predict the magnitude and impact that marking our hedges to market will have on our income from operations in future periods.

Intersegment Eliminations. During the three and six months endedJune 30, 2013 and 2012, our Upstream Segment sold natural gas and condensate to the Marketing and Trading Segment within our Midstream Business for resale. In addition, during the three and six months endedJune 30, 2013, our Upstream Segment sold natural gas to our Panhandle Segment.

General and Administrative Expenses. General and administrative expenses increased by $0.7 million and $2.7 million for the three and six months endedJune 30, 2013, respectively, as compared to the same periods in 2012. This increase was primarily due to higher salaries and benefits, which was due to (i) an increase in our headcount due to the Panhandle Acquisition and (ii) increased equity compensation expense due to additional grants.

We do not allocate our general and administrative expenses to our operational segments.

Total Other Expense.  Total other expense primarily consists of both realized and unrealized gains and losses from our interest rate swaps and interest expense related to our senior secured credit facility and our senior unsecured notes. During July 2012, in conjunction with our issuance of $250.0 million of senior unsecured notes, which increased our fixed interest rate exposure, we terminated the full $200.0 million notional amount of our existing 4.295% and 4.095% fixed rate interest rate swaps. During the three and six months endedJune 30, 2013, our realized settlement losses decreased by $1.8 million and $3.5 million, respectively, as compared to the three and six months endedJune 30, 2012, primarily due to the transactions described above. For the three and six months endedJune 30, 2013, we recognized unrealized gains of $1.5 million and $3.0 million, respectively, as compared to unrealized gains of $2.0 million and $3.8 million during the same period in 2012. These unrealized mark-to-market gains did not have any impact on cash activities for the period, and are excluded by definition from our calculation of Adjusted EBITDA.

Interest expense increased by $6.0 million and $12.8 million during the three and six months endedJune 30, 2013, respectively, as compared to the three and six months endedJune 30, 2012.  Interest expense is shown before the impact of our interest rate derivatives, which convert a portion of our outstanding debt from variable-rate interest obligations to fixed-rate interest obligations.  The increase in interest expense is due to the issuance of the senior unsecured notes, described above, along with increased borrowings on our revolving credit facility.

Income Tax (Benefit) Provision. Income tax provision for 2013 and 2012 relates to (i) state taxes due by us and (ii) federal taxes due by Eagle Rock Energy Acquisition Co., Inc. and Eagle Rock Energy Acquisition Co. II, Inc. and their wholly-owned subsidiary corporations, Eagle Rock Upstream Development Company, Inc. and Eagle Rock Upstream Development Company II, Inc., all of which are subject to federal income taxes.

Adjusted EBITDA

Adjusted EBITDA, as defined under "-Liquidity and Capital Resources - Non-GAAP Financial Measures," decreased by $1.8 million and $11.0 million from $57.7 million and $120.5 million for the three and six months endedJune 30, 2012, respectively, to $55.9 million and $109.5 million for the three and six months endedJune 30, 2013, respectively.

As described above, revenues minus cost of natural gas and NGLs for the Midstream Business (excluding unrealized gains from the Marketing and Trading Segment) increased by $10.6 million and increased by $14.1 million during the three and six months endedJune 30, 2013, respectively, as compared to the comparable period in 2012. The Upstream Segment revenues (excluding imbalances) increased $3.8 million and decreased by $6.0 million during the three and six months endedJune 30, 2013, respectively, as compared to the comparable period in 2012. Intercompany eliminations of revenues minus cost of natural gas and condensate resulted was flat for the three months endedJune 30, 2013 as compared to the comparable period in 2012. Intercompany eliminations of revenues minus cost of natural gas and condensate resulted in a $1.3 million decrease during the six months endedJune 30, 2013 as compared to the comparable period in 2012. Our Corporate and Other Segment's

41

realized commodity derivatives gains decreased by $8.3 million and $4.5 million during the three and six months endedJune 30, 2013, respectively, as compared to the comparable period in 2012. This resulted in total incremental revenues minus cost of natural gas and NGLs increasing by $6.1 million and $2.4 million during the three and six months endedJune 30, 2013, respectively, as compared to the comparable period in 2012.  The incremental revenue amounts are adjusted to exclude the impact of unrealized commodity derivatives and the non-cash mark-to-market Upstream Segment imbalances, none of which are included in the calculation of Adjusted EBITDA.

Operating expenses (including taxes other than income) for our Midstream Business increased by $8.9 million and $13.5 million for the three and six months endedJune 30, 2013, respectively, as compared to the same period in 2012, and operating expenses (including taxes other than income) for the Upstream Segment decreased $0.9 million and $1.6 million for the three and six months endedJune 30, 2013, respectively, as compared to the same period in 2012.

General and administrative expenses, excluding the impact of non-cash compensation charges related to our long-term incentive program and other non-recurring items and captured within our Corporate and Other Segment, decreased by less than $0.1 million for the three months endedJune 30, 2013 and increased by $1.5 million during the six months endedJune 30, 2013 as compared to the respective periods in 2012.

As a result, revenues (excluding the impact of unrealized commodity derivative activity) minus cost of natural gas, NGLs and condensate for the three and six months endedJune 30, 2013, as compared to the same period in 2012, increased by $6.1 million and $2.4 million, respectively, operating expenses increased by $8.0 million and $11.9 million, respectively, and general and administrative expenses was flat for the three months endedJune 30, 2013 as compared to the respective period in 2012 and increased by $1.5 million for the six months endedJune 30, 2013 as compared to the comparable period in 2012.  The decreases in revenues minus the cost of natural gas, NGLs and condensate and the increases in operating costs and general and administrative expenses, resulted in an decrease to Adjusted EBITDA for the three and six months endedJune 30, 2013, as compared to the three and six months endedJune 30, 2012.

LIQUIDITY AND CAPITAL RESOURCES

Historically, our sources of liquidity have included cash generated from operations, issuances of equity and debt securities and borrowings under our revolving credit facility. Our primary cash requirements have included general and administrative expenses, operating expenses, maintenance and growth capital expenditures, short-term working capital needs, interest payments on our outstanding debt, distributions to our unitholders and acquisitions of new assets or businesses.

We believe that our historical sources of liquidity will be sufficient to satisfy our short-term liquidity needs and to fund our committed capital expenditures for at least the next twelve months. Our growth strategy entails substantial expenditures on organic projects in our Midstream Business and new drilling activity in our Upstream Business. We also intend to continue to pursue attractive development and acquisition opportunities in the midstream and upstream sectors. Accordingly, we may utilize various available financing sources, including the issuance of equity or debt securities, to fund all or a portion of our organic growth expenditures and potential acquisitions. Our ability to complete future offerings of equity or debt securities and the timing of these offerings will depend upon various factors including prevailing market conditions and our financial condition.

Equity Offerings

On May 31, 2012, we announced a program through which we may issue common units, from time to time, with an aggregate market value of up to $100 million. We are under no obligation to issue equity under the program. We intend to use the net proceeds from any sales under the program for general partnership purposes, which may include, among other things, repayment of indebtedness, acquisitions, capital expenditures and additions to working capital. As of June 30, 2013, a total of 1,521,086 units had been issued under this program for net proceeds of approximately $13.0 million, of which 686,759 units were issued during the three months endedJune 30, 2013 for net proceeds of approximately $5.7 million. Issuance costs associated with the program for the three and six months endedJune 30, 2013 were $0.3 million.

During the first quarter of 2013, we closed an underwritten public offering of 10,350,000 common units for net proceeds of approximately $92.5 million. The net proceeds were used to repay a portion of the outstanding borrowings under our revolving credit facility.

Capital Expenditures

42

The energy business can be capital intensive, requiring significant investment for the acquisition or development of new facilities. We categorize our capital expenditures as (and, as necessary, allocate the attributable portion of our capital expenditures between) either:

• growth capital expenditures, which are made to (i) acquire, construct, expand or upgrade our gathering, processing and treating assets or (ii) grow our natural gas, NGL, crude or sulfur production; or

• maintenance capital expenditures, which are made to (i) replace partially or fully depreciated assets, meet regulatory requirements, or maintain the existing operating capacity of our gathering, processing and treating assets or (ii) maintain our natural gas, NGL, crude or sulfur production. With respect to maintenance capital expenditures intended to maintain the Partnership's natural gas, NGL, crude or sulfur production, we estimate these amounts based on current projections and expectations, and do not undertake to adjust any historical amounts based on the actual impact of such expenditures on production. As a result, the included amount of maintenance capital expenditures could fail to maintain production if actual performance does not meet projections and expectations, including, without limitation, on account of (i) unanticipated mechanical issues; (ii) unanticipated delays; (iii) lower than anticipated mechanical issues; and/or (iv) unanticipated loss of, or higher than anticipated decline in, existing production.

The primary impact of this categorization is that we reduce the amount of cash we consider available for distribution by the amount of our maintenance capital expenditures.

Our current 2013 capital budget anticipates that we will spend approximately $208 million in total, of which we expect approximately $60 million to be categorized as maintenance capital expenditures and $148 million to be categorized as growth capital expenditures. Our capital expenditures were approximately $67.4 million and $123.3 million for the three and six months endedJune 30, 2013, respectively, of which $14.9 million and $27.6 million were related to maintenance capital expenditures and $52.5 million and $95.7 million were related to growth capital expenditures. As a result of the hole stability and mechanical problems encountered during the process of drilling certain wells, our capital expenditures in our Upstream Segment for the six months ended June 30, 2013, were $18.3 million higher than our expectations.

In order to lower sulfur dioxide (SO₂) emissions from our Big Escambia Creek processing facility in Alabama, as required by our existing air emissions permit, our operating subsidiary initiated the first phase of an SO₂ emissions reduction project at our Big Escambia Creek processing facility in December 2011. This phase of the project involved adding a Superclaus reactor to the existing sulfur recovery unit to achieve the desired reduction in SO₂ emissions. The new unit began operations on December 17, 2012, and through June 30, 2013 had resulted in increased sulfur production and reductions in SO₂ emissions to levels well below the required permitted levels. The total cost of this phase was approximately $22.3 million net to our interest.

The second and final phase of our SO₂ emissions reduction project involves replacing or upgrading certain components of our existing sulfur recovery unit at the Big Escambia Creek processing facility. This phase is designed to improve the operational reliability of the processing facility, further increase the quantity of marketable sulfur recovered from the inlet gas stream, reduce the frequency of facility turnarounds, extend the facility's operating life and achieve cost savings across our operations in Southern Alabama. The improvements to our sulfur recovery unit will also further reduce SO₂ emissions, helping to ensure our compliance with the National Ambient Air Quality Standards the Environmental Protection Agency enacted in mid-2010. In the first of these planned upgrades, we expect to replace the incinerator portion of the sulfur recovery unit in 2014 at a cost of approximately $11.6 million net to our interest.

Distribution Policy

Our distribution policy is to distribute to our unitholders, on a quarterly basis, all of our available cash in the manner described below and as further described in our partnership agreement. Available cash generally means, for any quarter ending prior to liquidation, all cash and cash equivalents on hand at the end of that quarter (or, if the general partner chooses, on the date of determination) less the amount of cash reserves established by the general partner to:

• provide for the proper conduct of our business, including for future capital expenditures and credit and other needs;

• comply with applicable law or any partnership debt instrument or other agreement; or

• provide funds for distributions to unitholders in respect of any one or more of the next four quarters.

43

The actual distributions we will declare will be subject to our operating performance, prevailing market conditions (including forward oil, natural gas and sulfur prices), the impact of unforeseen events and the approval of our Board of Directors and will be done pursuant to our distribution policy.

Revolving Credit Facility

On June 22, 2011, we entered into an Amended and Restated Credit Agreement (the "Credit Agreement") with Wells Fargo Bank, National Association, as administrative and documentation agent and swingline lender, Bank of America, N.A. and The Royal Bank of Scotland plc, as co-syndication agents, and the other lenders who are parties to the Credit Agreement.

On December 31, 2012, aggregate commitments under the Credit Agreement increased from $675 million to $820 million. We have the option to request further increases, subject to the terms and conditions of the Credit Agreement, up to a total aggregate amount of $1.2 billion. Availability under the revolving credit facility is subject to a borrowing base comprised of two components: the upstream component and the midstream component. As of June 30, 2013, our borrowing base totaled approximately $803 million.

On July 23, 2013, we and our lenders amended the Credit Agreement to allow for a temporary step-up in the Total Leverage Ratio and the Senior Secured Leverage Ratio, as defined therein, through the third quarter of 2014 and the third quarter of 2013, respectively. The amendment also extends the period of time we are subject to the Senior Secured Leverage Ratio from September 30, 2013 to September 30, 2014. The amendment is effective as of June 30, 2013, and adjusts the Total Leverage Ratio and Senior Secured Leverage Ratio covenants as follows:

	Total Leverage Ratio		Senior Secured Leverage Ratio
Quarter ended	Amended	Previous	Amended	Previous
June 30, 2013	5.50x	4.75x	3.15x	2.85x
September 30, 2013	5.50x	4.75x	3.15x	2.85x
December 31, 2013	5.50x	4.50x	3.15x	NA
March 31, 2014	5.25x	4.50x	3.10x	NA
June 30, 2014	5.00x	4.50x	3.05x	NA
September 30, 2014	4.75x	4.50x	2.95x	NA
Thereafter	4.50x	4.50x	NA	NA

As of June 30, 2013, we had approximately $164.4 million of availability under the revolving credit facility.

Senior Unsecured Notes

On May 27, 2011, we completed the sale of $300 million of our 8.375% senior unsecured notes due 2019 (the "Senior Notes") through a private placement, which were exchanged for registered notes on February 15, 2012. The Senior Notes will mature on June 1, 2019, and interest is payable on June 1 and December 1 each year. We used the net proceeds of approximately $290.3 million to repay borrowings outstanding under our revolving credit facility.

On July 13, 2012, we completed the sale of an additional $250.0 million of Senior Notes under the same indenture through a private placement. After the original discount of $3.7 million and excluding related offering expenses, we received net proceeds of approximately $246.3 million, which were used to repay borrowings outstanding under our revolving credit facility.

Debt Covenants

Our revolving credit facility requires us to maintain certain leverage, current and interest coverage ratios. As of June 30, 2013, we were in compliance with all of our debt covenants, and we believe that we will remain in compliance with our financial covenants through 2013. Our financial covenant requirements and actual ratios as of June 30, 2013, are as follows:

44

	Per Credit Agreement	Actual
Interest coverage ratio	2.5 (Min)	3.4
Total leverage ratio	5.5 (Max)	4.7
Senior secured leverage ratio	3.15 (Max)	2.5
Current ratio	1.0 (Min)	1.7

Our long-term target is to maintain our ratio of outstanding debt to Adjusted EBITDA, or "total leverage ratio," at or below 3.5 to 1.0 on a long-term basis, while acknowledging that at times this ratio may exceed our targeted levels, particularly following acquisitions or major development projects. For example, our total leverage ratio exceeded our long-term target as of June 30, 2013, due in part to: (i) our borrowings related to our Panhandle acquisition on October 1, 2012; (ii) our funding of ongoing drilling and other capital projects; and (iii) lower NGL prices and other factors negatively impacting our Adjusted EBITDA. We expect our efforts to maintain or reduce our leverage ratio during 2013 will be primarily through investing in attractive growth opportunities that will increase our Adjusted EBITDA.

Our Senior Notes were issued under an indenture that contains certain covenants limiting our ability to, among others, pay distributions, repurchase our equity securities, make certain investments, incur additional indebtedness, and sell assets. At June 30, 2013, we were in compliance with our covenants under the Senior Notes indenture.

For a further discussion of our revolving credit facility and Senior Notes, see Note 8 to our consolidated financial statements included in Part II, Item 8. Financial Statements and Supplementary Data of our Annual Report on Form 10-K for the year ended December 31, 2012.

Cash Flows

Cash Distributions

On January 28, 2013, we declared our fourth quarter 2012 cash distribution of $0.22 per unit to our common unitholders of record as of the close of business on February 7, 2013. The distribution was paid on February 14, 2013.

On April 23, 2013, we declared our first quarter 2013 cash distribution of $0.22 per unit to our common unitholders of record as of the close of business on May 7, 2013 (excluding certain restricted unit grants). The distribution was paid on May 15, 2013.

On July 23, 2013, we declared our second quarter 2013 cash distribution of $0.22 per unit to our common unitholders of record as of the close of business on August 7, 2013 (excluding certain restricted unit grants). The distribution will be paid on August 14, 2013.

Working Capital

Working capital is the amount by which current assets exceed current liabilities. As of June 30, 2013, working capital was a negative $29.2 million as compared to a positive $0.5 million as of December 31, 2012.

The net decrease in working capital of $29.6 million from December 31, 2012 to June 30, 2013, resulted primarily from the following factors:

• accounts payable increased by $23.0 million primarily as a result of higher volumes and the timing of payments of unbilled expenditures

• risk management net working capital balance decreased by a net $9.9 million as a result of changes in current portion of mark-to-market unrealized positions as a result of increases to the forward natural gas, oil and NGL price curves;

• accrued liabilities increased by $7.5 million primarily reflecting accrued interest:

• prepayment and other current assets decreased $0.8 million primarily due to amortization of prepaid expenses.

These decreases were partially offset by the following factor:

45

• trade accounts receivable increased by $11.5 million primarily from higher volumes and the timing of receipts.

Cash Flows for the Six Months Ended June 30,2013 Compared to the Six Months Ended June 30,2012

Cash Flow from Operating Activities. Cash flows from operating activities increased $43.3 million during the six months endedJune 30, 2013, as compared to the six months endedJune 30, 2012. This increase was primarily due to timing of cash payments, partially offset by the timing of cash receipts and a decrease in our results of operations as a result of increased operating costs and lower realized settlements. Increased natural gas prices during the six months endedJune 30, 2013, resulted in us realizing lower net settlement gains on our commodity derivatives, of which $0.9 million was reclassed to cash flows from financing activities. During the three months endedJune 30, 2012, $8.4 million was reclassed to cash flows from financing activities. During the six months endedJune 30, 2013, we did not make any payments to unwind any derivative contracts. We made a payment of $1.1 million to partially unwind certain commodity derivative contracts during the six months endedJune 30, 2012.

Cash Flows from Investing Activities. Cash flows used in investing activities for the six months endedJune 30, 2013 were $140.5 million, as compared to cash flows used in investing activities of $152.2 million for the six months endedJune 30, 2012. The key difference between periods was the $11.4 million decrease in capital expenditures, in particular, decreased spending on drilling in our Upstream Segment for the six months endedJune 30, 2013 as compared to the same period in 2012. In addition, during the six months endedJune 30, 2013, we were only constructing our Wheeler plant, as compared to the same period in 2012, when we were constructing both our Woodall and Wheeler plants.  

Cash Flows from Financing Activities. Cash flows provided by financing activities during the six months endedJune 30, 2013 were $35.5 million as compared to cash flows provided by financing activities of $89.6 million for the six months endedJune 30, 2012. Key differences between periods included net proceeds of $98.2 million from our equity offering which closed on March 12, 2013, compared to net proceeds of $31.8 million from the exercise of warrants during the six months endedJune 30, 2012. Cash inflows related to our net proceeds on our revolving credit facility were $4.5 million during the six months endedJune 30, 2013, as compared to net proceeds of $106.4 million during the six months endedJune 30, 2012. Cash outflows related to our distributions increased to $67.1 million during the six months endedJune 30, 2013, as compared to $56.7 million during the six months endedJune 30, 2012, as a result of an increase in our units outstanding.

Hedging Strategy

We use a variety of hedging instruments such as fixed-price swaps, costless collars and put options to manage our risks related to our commodity price and interest rate exposure. At times our hedging strategy may involve adjusting strike prices of existing hedges to better reflect current market conditions or to meet other corporate objectives.  In addition, we may also terminate or unwind hedges or portions of hedges when the expected future volumes do not support the level of hedges.  Hedge transactions such as these impact our liquidity in that we are required to pay the present value of the difference between the hedged price and the current futures price.  These transactions also increase our exposure to the counterparties through which we execute the hedges.

For further description of our hedging activity, see Note 10 to our unaudited condensed consolidated financial statements included in Part I, Item 1. Financial Statements and Supplementary Data of this Form 10-Q.

Off-Balance Sheet Obligations

We had no off-balance sheet transactions or obligations as of June 30, 2013. 

Recent Accounting Pronouncements

For recent accounting pronouncements, please see Note 3 of our unaudited condensed consolidated financial statements included in Part I, Item 1. Financial Statements and Supplementary Data of this Form 10-Q.

Non-GAAP Financial Measures

We include in this report Adjusted EBITDA, a non-GAAP financial measure. We provide reconciliations of this non-GAAP financial measure to its most directly comparable financial measures as calculated and presented in accordance with U.S. GAAP.

46

We define Adjusted EBITDA as net income (loss) plus or (minus) income tax provision (benefit); interest-net, including realized interest rate risk management instruments and other expense; depreciation, depletion and amortization expense; impairment expense; other operating expense, non-recurring; other non-cash operating and general and administrative expenses, including non-cash compensation related to our equity-based compensation program; unrealized (gains) losses on commodity and interest rate risk management related instruments; gains (losses) on discontinued operations and other (income) expense.  We use Adjusted EBITDA as a measure of our core profitability to assess the financial performance of our assets. Adjusted EBITDA is also used as a supplemental financial measure by external users of our financial statements such as investors, commercial banks and research analysts.  For example, the compliance covenant used by our lenders under our revolving credit facility which is designed to measure the viability of us and our ability to perform under the terms of our revolving credit facility uses our Adjusted EBITDA.  We believe that investors benefit from having access to the same financial measures that our management team uses in evaluating performance.  Adjusted EBITDA is useful in determining our ability to sustain or increase distributions. By excluding unrealized derivative gains (losses), a non-cash, mark-to-market benefit (charge) which represents the change in fair market value of our executed derivative instruments and is independent of our assets’ performance or cash flow generating ability, we believe Adjusted EBITDA reflects more accurately our ability to generate cash sufficient to pay interest costs, support our level of indebtedness, make cash distributions to our unitholders and finance our maintenance capital expenditures. We further believe that Adjusted EBITDA also describes more accurately the underlying performance of our operating assets by isolating the performance of our operating assets from the impact of an unrealized, non-cash measure designed to describe the fluctuating inherent value of a financial asset. Similarly, by excluding the impact of non-recurring discontinued operations, Adjusted EBITDA provides users of our financial statements a more accurate picture of our current assets’ cash generation ability, independently from that of assets which are no longer a part of our operations. Our Adjusted EBITDA definition may not be comparable to Adjusted EBITDA or similarly titled measures of other entities, as other entities may not calculate Adjusted EBITDA in the same manner as us. For example, we include in Adjusted EBITDA the actual settlement revenue created from our commodity hedges by virtue of transactions undertaken by us to reset commodity hedges to higher prices or purchase puts or other similar floors despite the fact that we exclude from Adjusted EBITDA any charge for amortization of the cost of such commodity hedge reset transactions or puts. 

Adjusted EBITDA should not be considered an alternative to net income, operating income, cash flows from operating activities or any other measure of financial performance presented in accordance with U.S. GAAP.

Adjusted EBITDA does not include interest expense, income taxes or depreciation and amortization expense. Because we have borrowed money to finance our operations, interest expense is a necessary element of our costs and our ability to generate net income. Because we use capital assets, depreciation and amortization are also necessary elements of our costs. Therefore, any measures that exclude these elements have material limitations. To compensate for these limitations, we believe that it is important to consider both net income determined under U.S. GAAP, as well as Adjusted EBITDA, to evaluate our performance and liquidity.

The following table sets forth a reconciliation of Adjusted EBITDA to its most directly comparable financial measures calculated and presented in accordance with U.S. GAAP:

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Risk and Accounting Policies

We are exposed to market risks associated with adverse changes in commodity prices, interest rates and counterparty credit. We may use financial instruments such as put and call options, swaps and other derivatives to mitigate the effects of the identified risks. Adverse effects on our cash flow from changes in crude oil, natural gas, NGL product prices or interest rates could adversely impact our ability to make distributions to our unitholders, meet debt service obligations, fund required capital expenditures, and other similar requirements. Our management has established a comprehensive review of our market risks and has developed risk management policies and procedures to monitor and manage these market risks. Our general partner is responsible for the overall approval of market risk management policies, delegation of transaction authority levels, and for the establishment of a Risk Management Committee ("RMC"). The RMC is composed of officers (including, on an ex officio basis, our chief executive officer) who receive regular briefings on positions and exposures, credit exposures and overall risk management in the context of market activities. The RMC is responsible for the overall management of commodity price risk, interest rate risk and credit risk, including monitoring exposure limits.

Commodity Price Risk

We are exposed to the impact of market fluctuations in the prices of crude oil, natural gas, NGLs and other commodities as a result of our gathering, processing, producing and marketing activities, which produce a naturally long position in these commodities. Our profitability and cash flow are affected by changes in prices of these commodities. These prices are impacted by changes in the supply and demand for these commodities, as well as market uncertainty and other factors beyond our control. Historically, changes in the prices of NGLs have generally correlated with changes in the price of crude oil.

We manage this commodity price exposure through an integrated strategy that includes management of our contract portfolio, matching sales prices of commodities with purchases, optimization of our portfolio by monitoring basis and other price differentials in our areas of operations, and the use of derivative contracts. Crude oil, natural gas and NGL prices can also indirectly affect our profitability by influencing the level of drilling activity and related opportunities for our service.

We frequently use financial derivatives ("hedges") to reduce our exposure to commodity price risk. Historically, we have hedged a substantial portion of our exposure to changes in NGL prices with crude or natural gas hedges, which we call "proxy hedges." To the extent the price of the underlying physical product (NGL) does not correlate with the price of the designated proxy hedge product (crude or natural gas), these hedges can be ineffective in reducing our commodity price exposure. We have implemented a Risk Management Policy which allows management to execute crude oil, natural gas liquids and natural gas hedging instruments, which may include swaps, collars, options and other derivatives, in order to reduce exposure to substantial adverse changes in the prices of these commodities. These hedges are only intended to mitigate the risk associated with our natural physical position. We monitor and ensure compliance with this Risk Management Policy through senior level executives in our operations, finance and legal departments.

We have not designated our contracts as accounting hedges based on authoritative guidance. As a result, we mark our derivatives to market with the resulting change in fair value being included in our statement of operations. As of June 30, 2013, our commodity hedge portfolio totaled a net asset position of $47.4 million, consisting of assets aggregating $50.0 million and liabilities aggregating $2.6 million. For additional information about our hedging activities and related fair values, see Part I, Item 1. Financial Statement Notes 10 and 11.

We continually monitor our hedging and contract portfolio and expect to continue to adjust our hedge position as conditions warrant.

In addition, we market and trade natural gas. Though we intend for these activities to complement our existing operations, they may expose us to additional and different risks, as our activities are expected to be more comprehensive than our commodities derivative activities described above. To minimize our exposure to trading losses, we have established procedures to monitor and limit risk, including the use of value-at-risk metrics. 

Interest Rate Risk

We are exposed to variable interest rate risk as a result of borrowings under our revolving credit facility. To mitigate its interest rate risk, we have entered into various interest rate swaps. These swaps convert the variable-rate term loan into a fixed-rate obligation. The purpose of entering into these swaps is to eliminate interest rate variability by converting LIBOR-

49

based variable-rate payments to fixed-rate payments. Amounts received or paid under these swaps were recorded as reductions or increases in interest expense.

We have not designated our contracts as accounting hedges. As a result, we mark our derivatives to market with the resulting change in fair value included in our statement of operations. As of June 30, 2013, the fair value liability of these interest rate contracts totaled approximately $11.7 million. For additional information about our interest rate swaps and related fair values, see Part I, Item 1. Financial Statement Notes 10 and 11.

Credit Risk

Our principal natural gas sales customers are large gas marketing companies that, in turn, typically sell to large end users such as local distribution companies and electrical utilities. With respect to the sale of our NGLs and condensates, our principal customers are large natural gas liquids purchasers, fractionators and marketers, and large condensate aggregators that typically sell to large multi-national petrochemical and refining companies. We also sell a small amount of propane to medium sized, local distributors.

This concentration of credit risk may affect our overall credit risk in that these customers may be similarly affected by changes in the natural gas, natural gas liquids, petrochemical and other segments of the energy industry, the economy in general, the regulatory environment and other factors.

Our derivative counterparties at June 30, 2013, not including counterparties of our marketing and trading business, included BNP Paribas, Wells Fargo Bank, National Association, Comerica Bank, Bank of Nova Scotia, The Royal Bank of Scotland plc, Bank of America N.A., J Aron & Company (an affiliate of Goldman Sachs), ING Capital Markets LLC, BBVA Compass Bank, Royal Bank of Canada, Regions Financial Corporation and CITIBANK, N.A.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Based on the evaluation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act")) required by Exchange Act Rules 13a-15(b) or 15d-15(b), our principal executive officer and principal financial officer have concluded that as of the end of the period covered by this report, our disclosure controls and procedures were effective at the reasonable assurance level to ensure that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms, and include controls and procedures designed to ensure that information required to be disclosed by us in such reports is accumulated and communicated to our management, including the principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d - 15(f) under the Exchange Act) that occurred during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

Our operations are subject to a variety of risks and disputes normally incident to our business. As a result, we are and may, at any given time, be a defendant in various legal proceedings and litigation arising in the ordinary course of business. However, we are not currently a party to any material litigation. We maintain insurance policies with insurers in amounts and with coverage and deductibles that we, with the advice of our insurance advisors and brokers, believe are reasonable and prudent. We cannot, however, assure that this insurance will be adequate to protect us from all material expenses related to potential future claims for personal and property damage or that these levels of insurance will be available in the future at economical prices.

Item 1A. Risk Factors.

In addition to the other information set forth in this quarterly report on Form 10-Q, you should carefully consider the risks discussed in our annual report on Form 10-K for the year ended December 31, 2012, under the headings “Item 1. Business,” “Item 1A. Risk Factors,” “Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations” and “Item 7A. Quantitative and Qualitative Disclosures About Market Risk,” which risks could materially affect our business, financial condition or future results. There have been no material changes in our risk factors from those described in our Annual Report on Form 10-K for the year ended December 31, 2012.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

The following table sets forth certain information with respect to repurchases of common units during the three months endedJune 30, 2013:

Period	Total Number of Units Purchased		Average Price Paid Per Unit		Total Number of Units Purchased as Part of Publicly Announced Plans or Programs	Maximum Number (or Approximate Dollar Value) of Units that May Yet Be Purchased Under the Plans or Programs
April 1, 2013 - April 30, 2013	—		$	—	—	—
May 1, 2013 - May 31, 2013	(114,812	)	$	8.71	—	—
June 1, 2013 - June 30, 2013	—		$	—	—	—
Total	(114,812	)	$	8.71	—	—

All of the units were surrendered by employees to pay tax withholding in connection with the vesting of restricted common units. As a result, we are deeming the surrenders to be "repurchases." These repurchases were not part of a publicly announced program to repurchase our common units, nor do we have a publicly announced program to repurchase our common units.
