(Unaudited)

(1) General

Unless the context requires otherwise, references to “we,” “us,” “our” or the “Partnership” mean Crosstex Energy, L.P. and its consolidated subsidiaries.

Crosstex Energy, L.P., a Delaware limited partnership formed on July 12, 2002, is engaged in the gathering, transmission, processing and marketing of natural gas and natural gas liquids (NGLs). The Partnership connects the wells of natural gas producers in the geographic areas of its gathering systems in order to gather for a fee or purchase the gas production, processes natural gas for the removal of NGLs, transports natural gas and NGLs and ultimately provides natural gas and NGLs to a variety of markets. In addition, the Partnership purchases natural gas and NGLs from producers not connected to its gathering systems for resale and markets natural gas and NGLs on behalf of producers for a fee.

Crosstex Energy GP, LLC is the general partner of the Partnership. Crosstex Energy GP, LLC is a direct, wholly-owned subsidiary of Crosstex Energy, Inc. (CEI).

The accompanying condensed consolidated financial statements are prepared in accordance with the instructions to Form 10-Q, are unaudited and do not include all the information and disclosures required by generally accepted accounting principles for complete financial statements. All adjustments that, in the opinion of management, are necessary for a fair presentation of the results of operations for the interim periods have been made and are of a recurring nature unless otherwise disclosed herein. The results of operations for such interim periods are not necessarily indicative of results of operations for a full year. All significant intercompany balances and transactions have been eliminated in consolidation. Certain reclassifications have been made to the consolidated financial statements for the prior year to conform to the current presentation. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Partnership’s annual report on Form 10-K for the year ended December 31, 2010.

The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management of the Partnership 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 period. Actual results could differ from these estimates.

(2) Long-Term Debt

As of March 31, 2011 and December 31, 2010, long-term debt consisted of the following (in thousands):

	March 31,			December 31,
	2011			2010
Bank credit facility (due 2016), interest based on Prime and/or LIBOR plus an applicable margin, interest rate at March 31, 2011 and December 31, 2010 was 4.75% and 4.0%, respectively	$	16,000		$	—
Senior unsecured notes (due 2018), net of discount of $13.0 million and $13.5 million, respectively, which bear interest at the rate of 8.875%	711,986			711,512
Series B secured note assumed in the Eunice transaction (due 2011), which bears interest at the rate of 9.5%	7,058			7,058
	735,044			718,570
Less current portion	(7,058		)	(7,058		)
Debt classified as long-term	$	727,986		$	711,512

Credit Facility. As of March 31, 2011, there was $73.2 million in outstanding letters of credit and $16.0 million borrowed under the bank credit facility leaving approximately $330.8 million available for future borrowing based on the borrowing capacity of $420.0 million. In May 2011 the Partnership amended its credit facility as discussed in Note (11).

Table of Contents

CROSSTEX ENERGY, L.P.

Notes to Condensed Consolidated Financial Statements-(Continued)

The credit facility is guaranteed by substantially all of the Partnership’s subsidiaries and is secured by first priority liens on substantially all of the Partnership’s assets and those of the guarantors, including all material pipeline, gas gathering and processing assets, all material working capital assets and a pledge of all of the Partnership’s equity interests in substantially all of its subsidiaries.

Non Guarantors. The senior unsecured notes are jointly and severally guaranteed by each of the Partnership’s current material subsidiaries (the “Guarantors”), with the exception of its regulated Louisiana subsidiaries (which may only guarantee up to $500.0 million of the Partnership’s debt), CDC (the Partnership’s joint venture in Denton County, Texas which is not 100% owned by the Partnership) and Crosstex Energy Finance Corporation (a wholly owned Delaware corporation that was organized for the sole purpose of being a co-issuer of certain of the Partnership’s indebtedness, including the senior unsecured notes). Guarantors may not sell or otherwise dispose of all or substantially all of their properties or assets to, or consolidate with or merge into another company if such a sale would cause a default under the terms of the senior unsecured notes. Since certain wholly owned subsidiaries do not guarantee the senior unsecured notes, the condensed consolidating financial statements of the guarantors and non-guarantors for the three months ended March 31, 2011 and 2010 are disclosed below in accordance with Rule 3-10 of Regulation S-X.

(4) Partners’ Capital

(a) Cash Distributions

Unless restricted by the terms of the Partnership’s credit facility and/or senior unsecured note indenture, the Partnership must make distributions of 100% of available cash, as defined in the partnership agreement, within 45 days following the end of each quarter.

The Partnership’s fourth quarter 2010 distribution on its common and preferred units of $0.26 per unit was paid on February 11, 2011. The Partnership increased its first quarter 2011 distribution on its common and preferred units to $0.29 per unit to be paid on May 13, 2011.

(b) Earnings per Unit and Dilution Computations

The Partnership had common units and preferred units outstanding during the three months ended March 31, 2011 and 2010. The preferred units were issued in January 2010 at a discount, which represents a beneficial conversion feature (BCF), totaling $22.3 million to the market price of the common units they are convertible into. The BCFs attributable to the preferred units represent non-cash distributions that are treated in the same way as a cash distribution for earnings per unit computations for the three months ended March 31, 2010.

The preferred units are entitled to a quarterly distribution equal to the greater of $0.2125 per unit or the amount of the quarterly distribution per unit paid to common unitholders, subject to certain adjustments. Income is allocated to the preferred units in an amount equal to the quarterly distribution with respect to the period earned.

CROSSTEX ENERGY, L.P.

Notes to Condensed Consolidated Financial Statements-(Continued)

As required under FASB ASC 260-10-45-61A, unvested share-based payments that entitle employees to receive non-forfeitable distributions are considered participating securities, as defined in FASB ASC 260-10-20, for earnings per unit calculations. The following table reflects the computation of basic earnings per limited partner units for the periods presented (in thousands except per unit amounts):

	Three Months Ended March 31,
	2011			2010
Limited partners’ interest in net loss	$	(3,615	)	$	(41,236	)
Distributed earnings allocated to:
Common units (1)	$	14,625		$	—
Unvested restricted units (1)	299			—
Total distributed earnings	$	14,924		$	—
Undistributed loss allocated to:
Common units	$	(18,231	)	$	(40,129	)
Unvested restricted units	(308		)	(1,107		)
Total undistributed loss	$	(18,539	)	$	(41,236	)
Net loss allocated to:
Common units	$	(3,606	)	$	(40,129	)
Unvested restricted units	(9		)	(1,107		)
Total limited partners’ interest in net loss	$	(3,615	)	$	(41,236	)
Basic and diluted net loss per unit:
Basic and diluted common unit	$	(0.07	)	$	(0.81	)

(1) Represents declared distribution of $0.29 per unit payable on May 13, 2011.

The following are the unit amounts used to compute the basic and diluted earnings per limited partner unit for the three months ended March 31, 2011 and 2010 (in thousands):

	Three Months Ended March 31,
	2011	2010
Basic and diluted weighted average units outstanding:
Weighted average limited partner common units outstanding	50,472	49,739

All common unit equivalents were antidilutive in the three months ended March 31, 2011 and March 31, 2010 because the limited partners were allocated net losses in these periods.

The general partner is entitled to a 2.0% distribution with respect to all distributions made to common unitholders. If the distributions are in excess of $0.2125 per unit, distributions are made 98.0% to the common and preferred unitholders and 2.0% to the general partner, subject to the payment of incentive distributions as described below to the extent that certain target levels of cash distributions are achieved.

When quarterly distributions are made pro-rata to common and preferred unitholders, net income for the general partner consists of incentive distributions to the extent earned, a deduction for stock-based compensation attributable to CEI’s stock options and restricted shares and 2.0% of the original Partnership’s net income (loss) adjusted for the CEI stock-based compensation specifically allocated to the general partner. When quarterly distributions are made solely to the preferred unitholders, the net income for the general partner consists of the CEI stock-based compensation deduction and 2.0% of the Partnership’s net income (loss) after the allocation of income to the preferred unitholders with respect to their preferred distribution adjusted for the CEI stock-based compensation specifically allocated to the general partner.

(5) Employee Incentive Plans

(a) Long-Term Incentive Plans

The Partnership accounts for share-based compensation in accordance with FASB ASC 718, which requires compensation related to all stock-based awards, including stock options, be recognized in the consolidated financial statements.

The Partnership and CEI each have similar unit or share-based payment plans for employees, which are described below. Share-based compensation associated with the CEI share-based compensation plan awarded to officers and employees of the Partnership are recorded by the Partnership since CEI has no operating activities other than its interest in the Partnership. Amounts recognized in the consolidated financial statements with respect to these plans are as follows (in thousands):

	Three Months Ended
	March 31,
	2011		2010

(e) Crosstex Energy, Inc.’s Stock Options

CEI stock options have not been granted to officers or employees of the Partnership since 2005. There are 37,500 CEI stock options vested and exercisable at March 31, 2011.

(6) Derivatives

Commodity Swaps

The Partnership manages its exposure to fluctuations in commodity prices by hedging the impact of market fluctuations. Swaps are used to manage and hedge price and location risks related to these market exposures. Swaps are also used to manage margins on offsetting fixed-price purchase or sale commitments for physical quantities of natural gas and NGLs.

The Partnership commonly enters into various derivative financial transactions which it does not designate as accounting hedges. These transactions include “swing swaps,” “third party on-system financial swaps,” “storage swaps,” “basis swaps,” “processing margin swaps,” and “put options.” Swing swaps are generally short-term in nature (one month), and are usually entered into to protect

Table of Contents

CROSSTEX ENERGY, L.P.

Notes to Condensed Consolidated Financial Statements-(Continued)

against changes in the volume of daily versus first-of-month index priced gas supplies or markets. Third party on-system financial swaps are hedges that the Partnership enters into on behalf of its customers who are connected to its systems, wherein the Partnership fixes a supply or market price for a period of time for its customers, and simultaneously enters into the derivative transaction. Storage swap transactions protect against changes in the value of gas that the Partnership has stored to serve various operational requirements. Basis swaps are used to hedge basis location price risk due to buying gas into one of the Partnership’s systems on one index and selling gas off that same system on a different index. Processing margin financial swaps are used to hedge fractionation spread risk at the Partnership’s processing plants relating to the option to process versus bypassing the Partnership’s equity gas. Put options are purchased to hedge against declines in pricing and as such represent options, not obligations, to sell the related underlying volumes at a fixed price.

The remaining term of the contracts extend no later than December 2012 for derivatives. Changes in the fair value of the Partnership’s mark to market derivatives are recorded in earnings in the period the transaction is entered into. The effective portion of changes in the fair value of cash flow hedges is recorded in accumulated other comprehensive income until the related anticipated future cash flow is recognized in earnings. The ineffective portion is recorded in earnings immediately.

On all transactions where the Partnership is exposed to counterparty risk, the Partnership analyzes the counterparty’s financial condition prior to entering into an agreement, establishes limits and monitors the appropriateness of these limits on an ongoing basis. The Partnership primarily deals with two types of counterparties, financial institutions and other energy companies, when entering into financial derivatives on commodities. The Partnership has entered into Master International Swaps and Derivatives Association Agreements that allow for netting of swap contract receivables and payables in the event of default by either party. If the Partnership’s counterparties failed to perform under existing swap contracts, the Partnership’s maximum loss as of March 31, 2011 of $9.1 million would be reduced to $3.3 million due to the netting feature, all of which relates to other energy companies.

Impact of Cash Flow Hedges

The impact of realized gains or losses from derivatives designated as cash flow hedge contracts in the consolidated statements of operations is summarized below (in thousands):

	Three Months Ended

Increase (Decrease) in Midstream Revenue	2011			2010
Liquids	$	(660	)	$	(842	)
Realized loss included in Midstream revenue	$	(660	)	$	(842	)

Natural Gas

As of March 31, 2011, the Partnership has no balances in accumulated other comprehensive income related to natural gas.

Liquids

As of March 31, 2011, an unrealized derivative fair value net loss of $1.9 million related to cash flow hedges of liquids price risk was recorded in accumulated other comprehensive loss. Of this net amount, an approximate loss of $1.7 million is expected to be reclassified into earnings through March 2012. The actual reclassification to earnings will be based on mark to market prices at the contract settlement date, along with the realization of the gain or loss on the related physical volume, which amount is not reflected above.

Derivatives Other Than Cash Flow Hedges

Assets and liabilities related to third party derivative contracts, swing swaps, basis swaps, storage swaps, processing margin swaps and put options purchased are included in the fair value of derivative assets and liabilities and the profit and loss on the mark to market value of these contracts are recorded net as (gain) loss on derivatives in the consolidated statement of operations. The Partnership estimates the fair value of all of its energy trading contracts using actively quoted prices. The estimated fair value of energy trading contracts by maturity date was as follows (in thousands):

	Maturity Periods
	Less than one year			One to two years			More than two years		Total fair value
March 31, 2011	$	(2,809	)	$	(115	)	$	—	$	(2,924	)

(7) Fair Value Measurements

FASB ASC 820 sets forth a framework for measuring fair value and required disclosures about fair value measurements of assets and liabilities. Fair value under FASB ASC 820 is defined as the price at which an asset could be exchanged in a current transaction between knowledgeable, willing parties. A liability’s fair value is defined as the amount that would be paid to transfer the liability to a new obligor, not the amount that would be paid to settle the liability with the creditor. Where available, fair value is based on observable market prices or parameters or derived from such prices or parameters. Where observable prices or inputs are not available, use of unobservable prices or inputs are used to estimate the current fair value, often using an internal valuation model. These valuation techniques involve some level of management estimation and judgment, the degree of which is dependent on the item being valued.

FASB ASC 820 established a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.

The Partnership’s derivative contracts primarily consist of commodity swap contracts which are not traded on a public exchange. The fair values of commodity swap contracts are determined using discounted cash flow techniques. The techniques incorporate Level 1 and Level 2 inputs for future commodity prices that are readily available in public markets or can be derived from information available in publicly quoted markets. These market inputs are utilized in the discounted cash flow calculation considering the instrument’s term, notional amount, discount rate and credit risk and are classified as Level 2 in hierarchy.

Net assets (liabilities) measured at fair value on a recurring basis are summarized below (in thousands):

	March 31, 2011			December 31, 2010
	Level 2			Level 2
Commodity Swaps*	$	(5,017	)	$	(2,444	)
Total	$	(5,017	)	$	(2,444	)

*		Unrealized gains or losses on commodity derivatives qualifying for hedge accounting are recorded in accumulated other comprehensive income at each measurement date.

(8) Fair Value of Financial Instruments

The estimated fair value of the Partnership’s financial instruments has been determined by the Partnership using available market information and valuation methodologies. Considerable judgment is required to develop the estimates of fair value; thus, the estimates provided below are not necessarily indicative of the amount the Partnership could realize upon the sale or refinancing of such financial instruments (in thousands).

Fair value of derivative liabilities	11,041		11,041		9,136		9,136

The carrying amounts of the Partnership’s cash and cash equivalents, accounts receivable, and accounts payable approximate fair value due to the short-term maturities of these assets and liabilities.

The Partnership had $16.0 million in borrowings under its revolving credit facility included in long-term debt as of March 31, 2011 and no borrowing at December 31, 2010 and accrued interest under floating interest rate structures. Accordingly, the carrying value of such indebtedness approximates fair value for the amounts outstanding under the credit facility. As of March 31, 2011 and December 31, 2010, the Partnership also had borrowings totaling $712.0 million and $711.5 million, respectively, under senior unsecured notes with a fixed rate of 8.875% and a series B secured note with a principal amount of $7.1 million and $7.1 million, respectively, with a fixed rate of 9.5%. The fair value of the senior unsecured notes as of March 31, 2011 and December 31, 2010 was based on third party market quotations. The fair values of the series B secured note as of March 31, 2011 and December 31, 2010 were adjusted to reflect current market interest rates for such borrowings on the applicable date. The fair value of derivative contracts included in assets or liabilities for risk management activities represents the amount at which the instruments could be exchanged in a current arms-length transaction adjusted for credit risk of the Partnership and/or the counterparty as required under FASB ASC 820.

(9) Commitments and Contingencies

(a) Employment Agreements

Certain members of management of the Partnership are parties to employment contracts with the general partner. The employment agreements provide those senior managers with severance payments in certain circumstances and prohibit each such person from competing with the general partner or its affiliates for a certain period of time following the termination of such person’s employment.

(b) Environmental Issues

The Partnership acquired LIG Pipeline Company and its subsidiaries on April 1, 2004. Contamination from historical operations was identified during due diligence at a number of sites owned by the acquired companies. The seller, AEP, has indemnified the Partnership for these identified sites. Moreover, AEP has entered into an agreement with a third party company pursuant to which the remediation costs associated with these sites have been assumed by this third party company that specializes in remediation work. The Partnership does not expect to incur any material liability with these sites; however, there can be no assurance that the third parties who have assumed responsibility for remediation of site conditions will fulfill their obligations. In addition, the Partnership has disclosed possible Clean Air Act monitoring deficiencies it has discovered to the Louisiana Department of Environmental Quality (LDEQ) and is working with the department to correct these deficiencies and to address modifications to facilities to bring them into compliance. The Partnership does not expect to incur any material environmental liability associated with these issues.

(c) Other

The Partnership is involved in various litigation and administrative proceedings arising in the normal course of business. In the opinion of management, any liabilities that may result from these claims would not individually or in the aggregate have a material adverse effect on its financial position or results of operations.

On June 7, 2010, Formosa Plastics Corporation, Texas, Formosa Plastics Corporation, America, Formosa Utility Venture, Ltd., and Nan Ya Plastics Corporation, America filed a lawsuit against Crosstex Energy, Inc., Crosstex Energy, L.P., Crosstex Energy GP, L.P., Crosstex Energy GP, LLC, Crosstex Energy Services, L.P., and Crosstex Gulf Coast Marketing, Ltd. in the 24th Judicial District Court of Calhoun County, Texas, asserting claims for negligence, res ipsa loquitor, products liability and strict liability relating to the alleged receipt by the plaintiffs of natural gas liquids into their facilities from facilities operated by the Partnership. The lawsuit alleges that the plaintiffs have incurred at least $65.0 million in damages, including damage to equipment and lost profits. The

Table of Contents

CROSSTEX ENERGY, L.P.

Notes to Condensed Consolidated Financial Statements-(Continued)

Partnership has submitted the claim to its insurance carriers and intends to vigorously defend the lawsuit. The Partnership believes that any recovery would be within applicable policy limits. Although it is not possible to predict the ultimate outcome of this matter, the Partnership does not expect that an award in this matter will have a material adverse impact on its consolidated results of operations or financial condition.

At times, the Partnership’s gas-utility subsidiaries acquire pipeline easements and other property rights by exercising rights of eminent domain provided under state law. As a result, the Partnership (or its subsidiaries) is a party to a number of lawsuits under which a court will determine the value of pipeline easements or other property interests obtained by the Partnership’s gas utility subsidiaries by condemnation. Damage awards in these suits should reflect the value of the property interest acquired and the diminution in the value of the remaining property owned by the landowner. However, some landowners have alleged unique damage theories to inflate their damage claims or assert valuation methodologies that could result in damage awards in excess of the amounts anticipated. Although it is not possible to predict the ultimate outcomes of these matters, the Partnership does not expect that awards in these matters will have a material adverse impact on its consolidated results of operations or financial condition.

The Partnership (or its subsidiaries) is defending a number of lawsuits filed by owners of property located near processing facilities or compression facilities constructed by the Partnership as part of its systems. The suits generally allege that the facilities create a private nuisance and have damaged the value of surrounding property. Claims of this nature have arisen as a result of the industrial development of natural gas gathering, processing and treating facilities in urban and occupied rural areas. Although it is not possible to predict the ultimate outcomes of these matters, the Partnership does not believe that these claims will have a material adverse impact on its consolidated results of operations or financial condition.

(10) Segment Information

In 2010, the Partnership’s management realigned the composition of its segments. Accordingly, the Partnership has recast its segment information for prior periods to reflect this new alignment.

Identification of operating segments is based principally upon regions served. The Partnership’s reportable segments consist of the natural gas gathering, processing and transmission operations located in north Texas (NTX), the pipelines and processing plants located in Louisiana (LIG) and the south Louisiana processing and NGL assets (PNGL). Operating activity for assets sold in the comparative periods that was not considered discontinued operations as well as intersegment eliminations is shown in the corporate segment.

The Partnership evaluates the performance of its operating segments based on operating revenues and segment profits. Corporate expenses include general partnership expenses associated with managing all reportable operating segments. Corporate assets consist principally of property and equipment, including software, for general corporate support, working capital and debt financing costs.

Summarized financial information concerning the Partnership’s reportable segments is shown in the following table.

In May 2011, the Partnership amended its bank credit facility. The borrowing capacity under the credit facility has been increased from $420.0 million to $485.0 million and the maturity was extended from February 2014 to May 2016. Additionally, the amendment to the Partnership’s credit facility, among other things, (i) increased the maximum permitted leverage ratios during certain fiscal quarters and (ii) decreased the interest rate the Partnership pays on the obligations under the credit facility. Also under the amended credit facility, we increased the accordian from $100.0 million to $150.0 million, which permits us to increase our borrowing base if any bank in the credit facility or a new bank is willing to undertake such commitment.

The Partnership may prepay all loans under the amended credit facility at any time without premium or penalty (other than customary LIBOR breakage costs), subject to certain notice requirements.

Under the amended credit facility, borrowings bear interest at the Partnership’s option at the Eurodollar Rate (the British Bankers Association LIBOR Rate) plus an applicable margin or the Base Rate (the highest of the Federal Funds Rate plus 0.50%, the 30-day Eurodollar Rate plus 1.0%, or the administrative agent’s prime rate) plus an applicable margin. The Partnership pays a per annum fee (as described below) on all letters of credit issued under the amended credit facility and a commitment fee of between 0.375% and 0.50% per annum on the unused availability under the amended credit facility. The commitment fee, letter of credit fee and the applicable margins for the interest rate vary quarterly based on the Partnership’s leverage ratio (as defined in the credit facility, being generally computed as the ratio of total funded debt to consolidated earnings before interest, taxes, depreciation, amortization and certain other non-cash charges) and are as follows:

	Base Rate		Eurodollar Rate		Letter of Credit
Leverage Ratio	Loans		Loans		Fees
Greater than or equal to 4.50 to 1.00	2.00	%	3.00	%	3.00	%
Greater than or equal to 4.00 to 1.00 and less than 4.50 to 1.00	1.75	%	2.75	%	2.75	%

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

You should read the following discussion of our financial condition and results of operations in conjunction with the financial statements and notes thereto included elsewhere in this report.

Overview

We are a Delaware limited partnership formed on July 12, 2002. Our primary focus is on the gathering, processing, transmission and marketing of natural gas and natural gas liquids (NGLs), which we manage as regional reporting segments of midstream activity. Our geographic focus is in the north Texas Barnett Shale (NTX) and in Louisiana which has two reportable business segments (LIG and the south Louisiana processing and NGL assets, or PNGL). We manage our operations by focusing on gross operating margin because our business is generally to purchase and resell natural gas for a margin, or to gather, process, transport or market natural gas and NGLs for a fee. We define gross operating margin as operating revenue minus cost of purchased gas and NGLs.

Our gross operating margins are determined primarily by the volumes of natural gas gathered, transported, purchased and sold through our pipeline systems, processed at our processing facilities, and the volumes of NGLs handled at our fractionation facilities. We generate revenues from four primary sources:

· purchasing and reselling or transporting natural gas on the pipeline systems we own;

· processing natural gas at our processing plants;

· fractionating and marketing the recovered NGLs; and

· providing compression services.

We generally gather or transport gas owned by others through our facilities for a fee, or we buy natural gas from a producer, plant or shipper at either a fixed discount to a market index or a percentage of the market index, then transport and resell the natural gas at the market index. We attempt to execute all purchases and sales substantially concurrently, or we enter into a future delivery obligation, thereby establishing the basis for the margin we will receive for each natural gas transaction. Our gathering and transportation margins related to a percentage of the index price can be adversely affected by declines in the price of natural gas. We are also party to certain long-term gas sales commitments that we satisfy through supplies purchased under long-term gas purchase agreements. When we enter into those arrangements, our sales obligations generally match our purchase obligations. However, over time the supplies that we have under contract may decline due to reduced drilling or other causes and we may be required to satisfy the sales obligations by buying additional gas at prices that may exceed the prices received under the sales commitments. In our purchase/sale transactions, the resale price is generally based on the same index at which the gas was purchased. However, on occasion we have entered into certain purchase/sale transactions in which the purchase price is based on a production-area index and the sales price is based on a market-area index, and we capture the difference in the indices (also referred to as basis spread), less the transportation expenses from the two areas, as our margin. Changes in the basis spread can increase or decrease our margins.

One contract (the “Delivery Contract”) has a term to 2019 that obligates us to supply approximately 150,000 MMBtu/d of gas. At the time that we entered into the Delivery Contract in 2008, we had dedicated supply sources in the Barnett Shale that exceeded the delivery obligations under the Delivery Contract. Our agreements with these suppliers generally provided that the purchase price for the gas was equal to a portion of our sales price for such gas less certain fees and costs. Accordingly, we were initially able to generate a positive margin under the Delivery Contract. However, since entering into the Delivery Contract, there has been both (1) a reduction in the gas available under our supply contracts and (2) the discovery of other shale reserves, most notably the Haynesville and the Marcellus Shales, which has increased the supplies available to East Coast markets and reduced the basis spread between north Texas-area production and the market indices used in the Delivery Contract. Due to these factors, we have had to purchase a portion of the gas to fulfill our obligations under the Delivery Contract at market prices, resulting in negative margins under the Delivery Contract.

We have recorded a loss of approximately $3.0 million during the three months ended March 31, 2011 on the Delivery Contract. We currently expect that we will record a loss of approximately $10.0 million to $14.0 million on the Delivery Contract for the year ending December 31, 2011. This estimate is based on forward prices, basis spreads and other market assumptions as of March 31, 2011. These assumptions are subject to change if market conditions change during the remainder of 2011, and actual results under the Delivery Contract in 2011 could be substantially different from our current estimates, which may result in a greater loss than currently estimated.

Table of Contents

We also realize gross operating margins from our processing services primarily through three different contract arrangements: processing margins (margin), percentage of liquids (POL) or fixed-fee based. Under margin contract arrangements our gross operating margins are higher during periods of high liquid prices relative to natural gas prices. Gross operating margin results under POL contracts are impacted only by the value of the liquids produced with margins higher during periods of higher liquids prices. Under fixed-fee based contracts our gross operating margins are driven by throughput volume. See “Item 3. Quantitative and Qualitative Disclosures about Market Risk — Commodity Price Risk.”

Operating expenses are costs directly associated with the operations of a particular asset. Among the most significant of these costs are those associated with direct labor and supervision, property insurance, property taxes, repair and maintenance expenses, contract services and utilities. These costs are normally fairly stable across broad volume ranges, and therefore do not normally decrease or increase significantly in the short term with decreases or increases in the volume of gas or liquids moved through the asset.

Our general and administrative expenses are dictated by the terms of our partnership agreement. These expenses include the costs of employee, officer and director compensation and benefits properly allocable to us, and all other expenses necessary or appropriate to the conduct of business and allocable to us. Our partnership agreement provides that our general partner determines the expenses that are allocable to us in any reasonable manner determined by our general partner in its sole discretion.

Recent Developments

Credit Facility. On May 2, 2011, we amended our bank credit facility. This amendment increased our borrowing capacity from $420.0 million to $485.0 million, reduced its interest rates and improved terms of other covenants under the facility. See Note (11) to the condensed consolidated financial statements for a discussion of the amended terms.

Asset Expansions. We completed two expansion projects on our natural gas gathering system in the Barnett Shale play in North Texas that we expect will contribute to gathered volumes. We also reactivated our Eunice natural gas liquids (NGL) fractionator in south central Louisiana, which will give us operational flexibility, increased fractionation capacity and the ability to capture new NGL-related business. The two North Texas projects became operational in late March 2011 and the Eunice NGL fractionator became operational in early April 2011.

We expanded our natural gas gathering system in North Texas with the construction of a $25.0 million, 15-mile pipeline extension to serve major Barnett Shale producers. The project, which is supported by volumetric commitments, includes a seven-mile low-pressure pipeline, an eight-mile high-pressure pipeline and a compressor station in southwest Tarrant County that provides customers with greater takeaway capacity to accommodate their transportation requirements.

We also entered into a 10-year firm gathering and compression agreement with a major Barnett Shale producer for an additional 50 MMcf/d on our North Texas gathering system. We constructed a compressor station on an existing gathering line to accommodate the customer’s transportation requirements.

In south central Louisiana, our Eunice NGL fractionator was reactivated with the necessary equipment to accommodate 15,000 barrels of NGLs per day (“Bbls/d”). Additional capacity of 21,000 Bbls/d can be restarted as supplies grow. The Eunice start-up and expansion project increased our fractionation capacity for liquids products from 40,000 Bbls/d to 55,000 Bbls/d.

Non-GAAP Financial Measures

We include the following non-GAAP financial measures: Adjusted EBITDA and gross operating margin. We provide reconciliations of these non-GAAP financial measures to their most directly comparable financial measures as calculated and presented in accordance with generally accepted accounting principles, or GAAP.

We define adjusted EBITDA as net income plus interest expense, provision for income taxes and depreciation and amortization expense, impairments, stock-based compensation, loss on extinguishment of debt, (gain) loss on noncash derivatives and minority interest; less gain on sale of property. Adjusted EBITDA is used as a supplemental performance measure by our management and by external users of our financial statements such as investors, commercial banks, research analysts and others, to assess:

· financial performance of our assets without regard to financing methods, capital structure or historical cost basis;

Table of Contents

· the ability of our assets to generate cash sufficient to pay interest costs, support our indebtedness and make cash distributions to our unitholders and our general partner;

· our operating performance and return on capital as compared to those of other companies in the midstream energy sector, without regard to financing methods or capital structure; and

· the viability of acquisitions and capital expenditure projects and the overall rates of return on alternative investment opportunities.

Adjusted EBITDA is one of the critical inputs into the financial covenants within our credit facility. The rates we pay for borrowings under our credit facility are determined by the ratio of our debt to adjusted EBITDA. The calculation of these ratios allows for further adjustments to adjusted EBITDA for recent acquisitions and dispositions.

Adjusted EBITDA should not be considered an alternative to, or more meaningful than, net income, operating income, cash flows from operating activities or any other measure of financial performance presented in accordance with GAAP. Our adjusted EBITDA may not be comparable to similarly titled measures of other companies because other entities may not calculate adjusted EBITDA in the same manner.

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 cash available for distribution. 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 earnings determined under GAAP, as well as adjusted EBITDA, to evaluate our overall performance.

The following table provides a reconciliation of adjusted EBITDA to net income (loss):

Other (a)	1.8		3.2
Adjusted EBITDA	$	53.6	$	43.8

(a) Includes financial derivatives marked-to-market; income taxes; and minority interest.

We define gross operating margin, generally, as revenues minus cost of sales. We present gross operating margin by segment in “Results of Operations.” We disclose gross operating margin in addition to total revenue because it is the primary performance measure used by our management. We believe gross operating margin is an important measure because our business is generally to purchase and resell natural gas for a margin or to gather, process, transport or market natural gas and NGLs for a fee. Operating expense is a separate measure used by management to evaluate operating performance of field operations. Direct labor and supervision, property insurance, property taxes, repair and maintenance, utilities and contract services comprise the most significant portion of our operating expenses. These expenses are largely independent of the volumes we transport or process and fluctuate depending on the activities performed during a specific period. We do not deduct operating expenses from total revenue in calculating gross operating margin because we separately evaluate commodity volume and price changes in these margin amounts. As an indicator of our operating performance, gross operating margin should not be considered an alternative to, or more meaningful than, net income as determined in accordance with GAAP. Our gross operating margin may not be comparable to similarly titled measures of other companies because other entities may not calculate these amounts in the same manner.

Three Months Ended March 31, 2011 Compared to Three Months Ended March 31, 2010

Gross Operating Margin. Gross operating margin was $89.8 million for the quarter ended March 31, 2011 compared to $81.2 million for the three months ended March 31, 2010, an increase of $8.6 million, or 10.6%. The increase was due to higher margins on our gathering and transmission throughput volume, as well as a favorable NGL market throughout the quarter. The following provides additional details regarding this change in gross operating margin:

· The LIG segment contributed gross operating margin growth of $3.9 million for the three months ended March 31, 2011 compared to the three months ended March 31, 2010. The gathering and transmission assets generated approximately $3.1 million of gross operating margin growth primarily due to improved pricing and higher volumes on the northern part of the system. The improved processing environment contributed to a gain in the gross operating margins for the LIG processing plants for the period. The Plaquemine and Gibson plants combined for a gross operating margin gain of $0.8 million.

· The NTX segment had gross operating margin improvement of $1.8 million for the three months ended March 31, 2011 compared to the three months ended March 31, 2010. A gross operating margin increase of $3.9 million on the gathering and transmission assets in north Texas was offset by increased losses of $2.1 million on the Delivery Contract discussed previously.

· The improved processing and NGL marketing environment contributed to a $2.9 million increase in gross operating margin for the PNGL segment for the three months ended March 31, 2011 compared to the three months ended March 31, 2010. Fractionation and marketing activity generated a gross operating margin increase of approximately $1.8 million. In addition to the improved marketing environment, the inlet volume supplied to the fractionators was significantly increased through deliveries from rail cars and trucks. The Blue Water processing plant contributed a gross operating margin increase of $1.1 million due to an increase in plant run time and inlet volumes.

Operating Expenses. Operating expenses were $25.0 million for the three months ended March 31, 2011 compared to $26.5 million for the three months ended March 31, 2010, a decrease of $1.4 million, or 5.4%. The decrease is primarily due to normal fluctuations of repair and maintenance work during the three months ended March 31, 2011 compared to three months ended March 31, 2010.

General and Administrative Expenses. General and administrative expenses were $11.8 million for the three months ended March 31, 2011 compared to $12.7 million for the three months ended March 31, 2010, a decrease of $0.9 million, or 7.1%. The decrease is primarily due to a decrease in professional fees and services.

Gain on Sale of Property. Assets sold during the three months ended March 31, 2010 generated a net gain of $14.3 million, resulting primarily from the sale of the east Texas assets.

Gain/Loss on Derivatives. We had a loss on derivatives of $3.4 million for the three months ended March 31, 2011 compared to a loss of $3.7 million for the three months ended March 31, 2010. The derivative transaction types contributing to the net (gain) loss are as follows (in millions):

	Three Months Ended March 31,

Net losses related to commodity swaps	$	3.4	$	1.8		$	3.7		$	1.4

Depreciation and Amortization. Depreciation and amortization expenses were $29.7 million for the three months ended March 31, 2011 compared to $27.1 million for the three months ended March 31, 2010, an increase of $2.6 million, or 9.6%. The increase is primarily due to intangible amortization related to downward revision in future throughput volumes attributable to the gathering system in north Texas.

Interest Expense. Interest expense was $19.8 million for the three months ended March 31, 2011 compared to $26.9 million for the three months ended March 31, 2010, a decrease of $7.1 million, or 26.4%. Net interest expense consists of the following (in millions):

	Three Months Ended

Amortization of debt issue costs	1.6		2.1
Other	0.3		0.8
Total	$	19.8	$	26.9

Loss on Extinguishment of Debt. We recognized a loss on extinguishment of debt during the three months ended March 31, 2010 of $14.7 million. In February 2010, we repaid our existing credit facility and senior secured notes which resulted in make-whole interest payments on our senior secured notes and the write-off of unamortized debt costs totaling $14.7 million.

Critical Accounting Policies

Information regarding the Partnership’s Critical Accounting Policies is included in Item 7 of the Partnership’s Annual Report on Form 10-K for the year ended December 31, 2010.

Liquidity and Capital Resources

Cash Flows from Operating Activities. Net cash provided by operating activities was $1.8 million for the three months ended March 31, 2011 compared to net cash used in operating activities of $24.2 million for three months ended March 31, 2010. Income before non-cash income and expenses and changes in working capital for comparative periods were as follows (in millions):

	Three Months Ended
	March 31,
	2011			2010

Income before non-cash income and expenses	$	35.4		$	(26.9	)
Changes in working capital	$	(33.6	)	$	2.6

The primary reason for the increase in cash flow from income before non-cash income and expenses of $62.3 million from 2010 to 2011 relates to payments in 2010 for settlements of interest rate swaps, make-whole payments, and PIK notes associated with the extinguishment of debt combined with an increase in gross margin and a decrease in interest expense between the first quarter of 2011 as compared to the first quarter of 2010.

Cash Flows from Investing Activities. Net cash used in investing activities was $21.5 million for the three months ended March 31, 2011 and net cash provided by investing activities was $30.9 million for the three months ended March 31, 2010. Cash flows from investing activities for the three months ended March 31, 2010 includes proceeds from property sales of $39.7 million related to the sale of east Texas assets. Our primary investing outflows were capital expenditures, net of accrued amounts, as follows (in millions):

	Three Months Ended
	March 31,
	2011		2010
Growth capital expenditures	$	19.2	$	7.5
Maintenance capital expenditures	2.4		2.2
Total	$	21.6	$	9.7

Cash Flows from Financing Activities. Net cash provided by financing activities was $2.9 million for the three months ended March 31, 2011 and net cash used in financing activities was $6.9 million for the three months ended March 31, 2010. Our financings have primarily consisted of repayments under our bank credit facilities, repayments under capital lease obligations, senior secured note repayments, senior unsecured note borrowings and debt refinancing costs.

	Three Months Ended
	March 31,
	2011			2010
Net borrowings (repayments) under bank credit facilities	$	16.0		$	(491.6	)

Net repayments under capital lease obligations	(0.7		)	(0.6		)
Debt refinancing costs	(0.1		)	(28.1		)

Distributions to unitholders and our general partner also represent a primary use of cash in financing activities. No cash distributions were paid to common unitholders or the general partner due to the Partnership’s continued focus on reducing leverage during the three months ended March 31, 2010. Total cash distributions made during the three months ended March 31, 2011 were as follows (in millions):

	Three Months Ended
	March 31,
	2011
Common units	$	13.3
Preferred units	3.8
General partner	0.4
Total	$	17.5

In order to reduce our interest costs, we do not borrow money to fund outstanding checks until they are presented to the bank. Fluctuations in drafts payable are caused by timing of disbursements, cash receipts and draws on our revolving credit facility. We borrow money under our credit facility to fund checks as they are presented. As of March 31, 2011, we had approximately $330.8 million of available borrowing capacity under this facility. Changes in drafts payable for the three months ended 2011 and 2010 were as follows (in millions):

	Three Months Ended
	March 31,
	2011		2010
Increase (decrease) in drafts payable	$	6.3	$	(1.6	)

Working Capital Deficit. We had a working capital deficit of $12.2 million as of March 31, 2011. Changes in working capital may fluctuate significantly between periods even though our trade receivables and payables are typically collected and paid in 30 to 60 day pay cycles. A large volume of our revenues are collected and a large volume of our gas purchases are paid near each month end or the first few days of the following month so receivable and payable balances at any month end may fluctuate significantly depending on the timing of these receipts and payments. In addition, although we strive to minimize our natural gas and NGLs in inventory, these working inventory balances may fluctuate significantly from period to period due to operational reasons and due to changes in natural gas and NGL prices. Working capital also includes our mark to market derivative assets and liabilities associated with our commodity derivatives which may fluctuate significantly due to the changes in natural gas and NGL prices.

Off-Balance Sheet Arrangements. We had no off-balance sheet arrangements as of March 31, 2011.

Capital Requirements. During the three months ended March 31, 2011, our growth capital investments were $19.2 million, which were funded by internally generated cash flow and from borrowings under our credit facility. Our current capital spending projection for 2011 is approximately $50.0 million related to identified growth projects including $19.2 million incurred during the first quarter of 2011. We may identify more growth projects during 2011 in addition to projects currently budgeted.

As of March 31, 2011, our bank credit facility had a borrowing capacity of $420.0 million and there was $73.2 million in letters of credit issued and outstanding under the bank credit facility and $16.0 million of borrowings outstanding, leaving approximately $330.8 million available for future borrowing. The bank credit facility is guaranteed by substantially all of our subsidiaries. The bank credit facility matures in February 2014.

On May 2, 2011, we amended our bank credit facility. This amendment increased our borrowing capacity from $420.0 million to $485.0 million, reduced our interest rates and improved terms of other covenants under the facility. See Note (11) to the condensed consolidated financial statement for a discussion of the amended terms.

Recent Accounting Pronouncements

In January 2010, the FASB issued Accounting Standards Update (ASU) 2010-06, Improving Disclosures about Fair Value Measurements, which amends FASB ASC Topic 820, Fair Value Measurements and Disclosures. The ASU requires reporting entities to make new disclosures about recurring or nonrecurring fair-value measurements including significant transfers into and out of Level 1 and Level 2 fair-value measurements and information about purchases, sales, issuances, and settlements on a gross basis in the reconciliation of Level 3 fair-value measurements. The ASU also clarifies existing fair-value measurement disclosure guidance about the level of disaggregation, inputs, and valuation techniques. We have evaluated the ASU and determined that we are not currently impacted by the update.

Disclosure Regarding Forward-Looking Statements

This Quarterly Report on Form 10-Q includes forward-looking statements. Statements included in this report which are not historical facts are forward-looking statements. These statements can be identified by the use of forward-looking terminology including “forecast,” “may,” “believe,” “will,” “expect,” “anticipate,” “estimate,” “continue” or other similar words. These statements discuss future expectations, contain projections of results of operations or of financial condition or state other “forward-looking” information. Such statements reflect our current views with respect to future events based on what we believe are reasonable assumptions; however, such statements are subject to certain risks and uncertainties. In addition to specific uncertainties discussed elsewhere in this Form 10-Q, the risk factors set forth in Part I, “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2010, and those set forth in Part II, “Item 1A. Risk Factors” of this report, if any, may affect our performance and results of operations. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may differ materially from those in the forward-looking statements. We disclaim any intention or obligation to update or review any forward-looking statements or information, whether as a result of new information, future events or otherwise.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Market risk is the risk of loss arising from adverse changes in market rates and prices. Our primary market risk is the risk related to changes in the prices of natural gas and NGLs. In addition, we are exposed to the risk of changes in interest rates on our floating rate debt.

On July 21, 2010, President Obama signed the Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd-Frank”) into law, a part of which relates to increased regulation of the markets for derivative products of the type we use to manage areas of market risk. While the Commodity Futures Trading Commission has yet to issue regulations to implement this increased regulation, Dodd-Frank may result in increased costs to us to implement our market risk management strategy.

Interest Rate Risk

We are exposed to interest rate risk on our variable rate bank credit facility. At March 31, 2011, we had $16.0 million in borrowings under this facility. A 1% increase or decrease in interest rates would not materially impact the interest expense on this borrowing.

At March 31, 2011, we had total fixed rate debt obligations of $719.0 million, consisting of our senior unsecured notes with an interest rate of 8.875% and a series B secured note with an interest rate of 9.5%. The fair value of these fixed rate obligations was approximately $810.6 million as of March 31, 2011. We estimate that a 1% increase or decrease in interest rates would increase or decrease the fair value of such debt by $29.6 million.

Commodity Price Risk

We are subject to significant risks due to fluctuations in commodity prices. Our exposure to these risks is primarily in the gas processing component of our business. We currently process gas under three main types of contractual arrangements:

1. Processing margin contracts: Under this type of contract, we pay the producer for the full amount of inlet gas to the plant, and we make a margin based on the difference between the value of liquids recovered from the processed natural gas as compared to the value of the natural gas volumes lost (“shrink”) and the cost of fuel used in processing. The shrink and fuel losses are referred to as plant thermal reduction or PTR. Our margins from these contracts are high during periods of high liquids prices relative to natural gas prices, and can be negative during periods of high natural gas prices relative to liquids prices. However, we mitigate our risk of processing natural gas when margins are negative primarily through our ability to bypass processing when it is not profitable for us, or by contracts that revert to a minimum fee for processing if the natural gas must be processed to meet pipeline quality specifications.

2. Percent of liquids contracts: Under these contracts, we receive a fee in the form of a percentage of the liquids recovered, and the producer bears all the cost of the natural gas shrink. Therefore, our margins from these contracts are greater during

Table of Contents

periods of high liquids prices. Our margins from processing cannot become negative under percent of liquids contracts, but do decline during periods of low NGL prices.

3. Fee based contracts: Under these contracts we have no commodity price exposure and is paid a fixed fee per unit of volume that is processed.

Gas processing margins by contract types and gathering and transportation margins as a percent of total gross operating margin for the comparative year-to-date periods are as follows:

	Three Months Ended
	March 31,
	2011		2010
Gathering and transportation margin	55.7	%	60.2	%

Gas processing margins:
Processing margin	17.9	%	13.4	%
Percent of liquids	12.2	%	13.7	%
Fee based	14.2	%	12.7	%
Total gas processing	44.3	%	39.8	%

Total	100.0	%	100.0	%

We have hedges in place at March 31, 2011 covering a portion of the liquids volumes we expect to receive under percent of liquids (POL) contracts. The hedges done via swaps are set forth in the following table. The relevant payment index price is the monthly average of the daily closing price for deliveries of commodities into Mont Belvieu, Texas as reported by the Oil Price Information Service (OPIS).

In addition, we have hedges in place covering 132 MBbls of Ethane for the final two quarters of 2011 done via the purchase of puts. The net fair value asset of the puts as of March 31, 2011 was less than $0.1 million.

We have hedged our exposure to declines in prices for NGL volumes produced for our account. The NGL volumes hedged, as set forth above, focus on our POL contracts. We hedge our POL exposure based on volumes we consider hedgeable (volumes committed under contracts that are long term in nature) versus total POL volumes that include volumes that may fluctuate due to contractual

terms, such as contracts with month to month processing options. We have hedged 76.3% of our hedgeable volumes at risk through December 2011 (31.7% of total volumes at risk through December 2011). We have also hedged 28.6% of our hedgeable volumes at risk for 2012 (12.6% of total volumes at risk for 2012).

We also have hedges in place at March 31, 2011 covering the fractionation spread risk related to our processing margin contracts as set forth in the following table:

* weighted average

In relation to our fractionation spread risk, as set forth above, we have hedged 55.2% of our hedgeable liquids volumes at risk through December 31, 2011 (20.4% of total liquids volumes at risk) and 59.2% of the related hedgeable PTR volumes through December 31, 2011 (21.5% of total PTR volumes). We have also hedged 50.6% of our hedgeable liquids volumes at risk for the first six months of 2012 (18.8% of total liquids volumes at risk) and 61.3% of the related hedgeable PTR volumes for the first six months of 2012 (22.3% of total PTR volumes).

We are also subject to price risk to a lesser extent for fluctuations in natural gas prices with respect to a portion of our gathering and transport services. Approximately 8.9% of the natural gas we market is purchased at a percentage of the relevant natural gas index price, as opposed to a fixed discount to that price.

Another price risk we face is the risk of mismatching volumes of gas bought or sold on a monthly price versus volumes bought or sold on a daily price. We enter each month with a balanced book of natural gas bought and sold on the same basis. However, it is normal to experience fluctuations in the volumes of natural gas bought or sold under either basis, which leaves us with short or long positions that must be covered. We use financial swaps to mitigate the exposure at the time it is created to maintain a balanced position.

Our primary commodity risk management objective is to reduce volatility in our cash flows. We maintain a risk management committee, including members of senior management, which oversees all hedging activity. We enter into hedges for natural gas and NGLs using over-the-counter derivative financial instruments with only certain well-capitalized counterparties which have been approved by our risk management committee.

Table of Contents

The use of financial instruments may expose us to the risk of financial loss in certain circumstances, including instances when (1) sales volumes are less than expected requiring market purchases to meet commitments or (2) our counterparties fail to purchase the contracted quantities of natural gas or otherwise fail to perform. To the extent that we engage in hedging activities we may be prevented from realizing the benefits of favorable price changes in the physical market. However, we are similarly insulated against unfavorable changes in such prices.

As of March 31, 2011, outstanding natural gas swap agreements, NGL swap agreements, swing swap agreements, storage swap agreements and other derivative instruments were a net fair value liability of $5.0 million. The aggregate effect of a hypothetical 10% increase in gas and NGL prices would result in an increase of approximately $3.4 million in the net fair value liability of these contracts as of March 31, 2011 to a net fair value liability of approximately $8.4 million.

Item 4. Controls and Procedures
