	1.  Basis of Presentation and Summary of Significant Accounting Policies
	The accompanying unaudited condensed consolidated financial statements of Exterran Partners, L.P. (“we,” “our,” “us,” or the “Partnership”) included herein have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S.”) (“GAAP”) for interim financial information and the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP are not required in these interim financial statements and have been condensed or omitted. Management believes that the information furnished includes all adjustments, consisting only of normal recurring adjustments, that are necessary to present fairly our consolidated financial position, results of operations and cash flows for the periods indicated. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements presented in our Annual Report on Form 10-K for the year ended December 31, 2013. That report contains a more comprehensive summary of our accounting policies. The interim results reported herein are not necessarily indicative of results for a full year.
	Organization
	Exterran General Partner, L.P. is our general partner and an indirect wholly-owned subsidiary of Exterran Holdings, Inc. (individually, and together with its wholly-owned subsidiaries, “Exterran Holdings”). As Exterran General Partner, L.P. is a limited partnership, its general partner, Exterran GP LLC, conducts our business and operations, and the board of directors and officers of Exterran GP LLC, which we refer to herein as our board of directors and our officers, make decisions on our behalf.
	Comprehensive Income (Loss)
	Components of comprehensive income (loss) are net income (loss) and all changes in equity during a period except those resulting from transactions with our limited partners or general partner. Our accumulated other comprehensive income (loss) consists only of derivative financial instruments. Changes in accumulated other comprehensive income (loss) represent changes in the fair value of derivative financial instruments that are designated as cash flow hedges and to the extent the hedge is effective and the amortization of terminated interest rate swaps. See Note 7 for additional disclosures related to comprehensive income (loss).
	Financial Instruments
	Our financial instruments consist of cash, escrow deposit, trade receivables, interest rate swaps and debt. At March 31, 2014 and December 31, 2013, the estimated fair values of these financial instruments approximated their carrying amounts as reflected in our condensed consolidated balance sheets. The fair value of our fixed rate debt was estimated based on quoted market yields in inactive markets, which are Level 2 inputs. The fair value of our floating rate debt was estimated using a discounted cash flow analysis based on interest rates offered on loans with similar terms to borrowers of similar credit quality, which are Level 3 inputs. See Note 8 for additional information regarding the fair value hierarchy.
	The following table summarizes the carrying amount and fair value of our debt as of March 31, 2014 and December 31, 2013 (in thousands):
		March 31, 2014					December 31, 2013
		Carrying			Fair Value		Carrying		Fair Value
		Amount					Amount
	Fixed rate debt	$	345,095		$	350,000	$	344,955	$	346,000
	Floating rate debt	456,500			457,000		413,000		413,000
	Total debt	$	801,595		$	807,000	$	757,955	$	759,000
	GAAP requires that all derivative instruments (including certain derivative instruments embedded in other contracts) be recognized in the balance sheet at fair value and that changes in such fair values be recognized in earnings (loss) unless specific hedging criteria are met. Changes in the values of derivatives that meet these hedging criteria will ultimately offset related earnings effects of the hedged item pending recognition in earnings.
	Earnings (Loss) Per Common Unit
	The computation of earnings (loss) per common unit is based on the weighted average number of common units (also referred to as limited partner units) outstanding during the applicable period. Basic earnings (loss) per common unit is determined by dividing net income (loss) allocated to the common units after deducting the amount allocated to our general partner (including distributions to our general partner on its incentive distribution rights) by the weighted average number of outstanding common units during the period.
	When computing earnings per common unit in periods when distributions are greater than earnings (loss), the amount of the incentive distribution rights, if any, is deducted from net income (loss) and allocated to our general partner for the corresponding period. The remaining amount of net income (loss), after deducting the incentive distribution rights, is allocated between the general partner and common units based on how our partnership agreement allocates net losses.
	When computing earnings (loss) per common unit in periods when earnings (loss) are greater than distributions, earnings are allocated to the general partner and common units based on how our partnership agreement would allocate earnings if the full amount of earnings for the period had been distributed. This allocation of net income (loss) does not impact our total net income (loss), consolidated results of operations or total cash distributions; however, it may result in our general partner being allocated additional incentive distributions for purposes of our earnings (loss) per unit calculation, which could reduce net income per common unit. However, as required by our partnership agreement, we determine cash distributions based on available cash and determine the actual incentive distributions allocable to our general partner based on actual distributions.
	The potentially dilutive securities issued by us include phantom units, which do not require an adjustment to the amount of net income (loss) used for computing dilutive earnings per common unit. The following table shows the potential common units that were included in computing diluted earnings (loss) per common unit (in thousands):
		Three Months Ended March 31,
		2014		2013
	Weighted average common units outstanding — used in basic earnings per common unit	49,429		42,278
	Net dilutive potential common units issuable:

April 2014 MidCon Acquisition and March 2013 Contract Operations Acquisition	'
	2.  April 2014 MidCon Acquisition and March 2013 Contract Operations Acquisition
	On February 27, 2014, we entered into a Purchase and Sale Agreement with MidCon Compression, L.L.C. (“MidCon”) to acquire natural gas compression assets, including a fleet of 337 compressor units, comprising approximately 444,000 horsepower, a tract of real property and the facility located thereon, a fleet of vehicles, personal property and parts inventory from MidCon (the “April 2014 MidCon Acquisition”). In connection with entering into this agreement, we made an escrow deposit of $17.0 million, which is reflected in intangible and other assets, net, in our condensed consolidated balance sheet as of March 31, 2014. The compressor units were previously used by MidCon to provide compression services to a subsidiary of Access Midstream Partners LP (“Access”). On April 10, 2014, we completed the April 2014 MidCon Acquisition for $362.8 million, funding it with a combination of net proceeds from an equity offering and a senior notes offering (see Note 13). Effective as of the closing of the acquisition, we and Access entered into a seven-year contract operations services agreement under which we will provide compression services to Access. During the three months ended March 31, 2014, we incurred transaction costs of approximately $1.5 million related to the April 2014 MidCon Acquisition, which is reflected in other (income) expense, net, in our condensed consolidated statements of operations.
	At the closing of the acquisition, we directed MidCon to sell $9.4 million of the assets acquired in the acquisition, including a tract of real property and the facility located thereon, a fleet of vehicles, personal property and parts inventory, to a wholly-owned subsidiary of Exterran Holdings that is our indirect parent company. Our portion of the total purchase price was $353.4 million.
	The initial accounting for the April 2014 MidCon Acquisition was incomplete at the time these financial statements were available for issuance. We intend to complete the allocation of the acquisition price to identifiable assets and liabilities associated with the April 2014 MidCon Acquisition in the second quarter of 2014 and provide required disclosures in our consolidated financial statements beginning in the second quarter of 2014.
	In March 2013, we acquired from Exterran Holdings contract operations customer service agreements with 50 customers and a fleet of 363 compressor units used to provide compression services under those agreements, comprising approximately 256,000 horsepower, or 8% (by then available horsepower) of the combined U.S. contract operations business of Exterran Holdings and us (the “March 2013 Contract Operations Acquisition”). The acquired assets also included 204 compressor units, comprising approximately 99,000 horsepower, previously leased from Exterran Holdings to us and contracts relating to approximately 6,000 horsepower of compressor units we already owned and previously leased to Exterran Holdings. At the acquisition date, the acquired fleet assets had a net book value of $158.5 million, net of accumulated depreciation of $94.9 million. Total consideration for the transaction was approximately $174.0 million, excluding transaction costs. In connection with this acquisition, we issued approximately 7.1 million common units to Exterran Holdings and approximately 145,000 general partner units to our general partner.
	In connection with this acquisition, we were allocated $3.1 million finite life intangible assets associated with customer relationships of Exterran Holdings’ North America contract operations segment. The amounts allocated were based on the ratio of fair value of the net assets transferred to us to the total fair value of Exterran Holdings’ North America contract operations segment. These intangible assets are being amortized through 2024, based on the present value of income expected to be realized from these intangible assets.
	Because Exterran Holdings and we are considered entities under common control, GAAP requires that we record the assets acquired and liabilities assumed from Exterran Holdings in connection with the March 2013 Contract Operations Acquisition using Exterran Holdings’ historical cost basis in the assets and liabilities. The difference between the historical cost basis of the assets acquired and liabilities assumed and the purchase price is treated as either a capital contribution or distribution. As a result, we recorded a capital distribution of $12.4 million for the March 2013 Contract Operations Acquisition during the three months ended March 31, 2013.
	An acquisition of a business from an entity under common control is generally accounted for under GAAP by the acquirer with retroactive application as if the acquisition date was the beginning of the earliest period included in the financial statements. Retroactive effect to the March 2013 Contract Operations Acquisition was impracticable because such retroactive application would have required significant assumptions in a prior period that cannot be substantiated. Accordingly, our financial statements include the assets acquired, liabilities assumed, revenue and direct operating expenses associated with the acquisition beginning on the date of such acquisition. However, the preparation of pro forma financial information allows for certain assumptions that do not meet the standards of financial statements prepared in accordance with GAAP.
	Pro Forma Financial Information
	Pro forma financial information for the three months ended March 31, 2013 has been included to give effect to the additional assets acquired in the March 2013 Contract Operations Acquisition. The March 2013 Contract Operations Acquisition is presented in the pro forma financial information as though the transaction occurred as of January 1, 2013. The pro forma financial information reflects the following transactions:
	As related to the March 2013 Contract Operations Acquisition:
	·                       our acquisition in March 2013 of certain contract operations customer service agreements and compression equipment from Exterran Holdings; and
	·                       our issuance of approximately 7.1 million common units to Exterran Holdings and approximately 145,000 general partner units to our general partner.
	The pro forma financial information below is presented for informational purposes only and is not necessarily indicative of our results of operations that would have occurred had the transaction been consummated at the beginning of the period presented, nor is it necessarily indicative of future results. The pro forma consolidated financial information below was derived by adjusting our historical financial statements.
	The following table shows pro forma financial information for the three months ended March 31, 2013 (in thousands, except per unit amounts):
		Three Months
		Ended March 31,
		2013
	Revenue	$	118,407
	Net income	$	18,876
	Basic earnings per common unit	$	0.35
	Diluted earnings per common unit	$	0.35
	Pro forma net income (loss) per common unit is determined by dividing the pro forma net income (loss) that would have been allocated to our common unitholders by the weighted average number of common units outstanding after the completion of the transactions included in the pro forma consolidated financial statements. To the extent that the quarterly distributions exceed certain targets, our partnership agreement entitles our general partner to receive certain incentive distributions that will result in more net income (loss) proportionately being allocated to our general partner than to our common unitholders. The pro forma net income (loss) per limited partner unit calculations reflect pro forma incentive distributions to our general partner. There was no additional pro forma reduction of net income allocable to our limited partners, including the amount of additional incentive distributions that would have occurred, for the three months ended March 31, 2013.

	3.  Related Party Transactions
	We are a party to an omnibus agreement with Exterran Holdings, our general partner and others (as amended and/or restated, the “Omnibus Agreement”), which includes, among other things:
	·             certain agreements not to compete between Exterran Holdings and its affiliates, on the one hand, and us and our affiliates, on the other hand;
	·             Exterran Holdings’ obligation to provide all operational staff, corporate staff and support services reasonably necessary to operate our business and our obligation to reimburse Exterran Holdings for such services, subject to certain limitations and the cost caps discussed below;
	·             the terms under which we, Exterran Holdings, and our respective affiliates may transfer, exchange or lease compression equipment among one another;
	·             the terms under which we may purchase newly-fabricated contract operations equipment from Exterran Holdings;
	·             Exterran Holdings’ grant to us of a license to use certain intellectual property, including our logo; and
	·             Exterran Holdings’ and our obligations to indemnify each other for certain liabilities.
	The Omnibus Agreement will terminate upon a change of control of Exterran GP LLC, our general partner or us, and certain provisions of the Omnibus Agreement will terminate upon a change of control of Exterran Holdings. Provisions such as non-competition, transfers of compression equipment and caps on operating and selling, general and administrative (“SG&A”) expenses will terminate on December 31, 2014, unless extended.
	Pursuant to the Omnibus Agreement, we may purchase newly-fabricated compression equipment from Exterran Holdings or its affiliates at Exterran Holdings’ cost to fabricate such equipment plus a fixed margin of 10%, which may be modified with the approval of Exterran Holdings and the conflicts committee of our board of directors. During the three months ended March 31, 2014 and 2013, we purchased $40.7 million and $22.5 million, respectively, of newly-fabricated compression equipment from Exterran Holdings. Transactions between us and Exterran Holdings and its affiliates are transactions between entities under common control. Under GAAP, transfers of assets and liabilities between entities under common control are to be initially recorded on the books of the receiving entity at the carrying value of the transferor. Any difference between consideration given and the carrying value of the assets or liabilities is treated as a capital distribution or contribution. As a result, the newly-fabricated compression equipment purchased during the three months ended March 31, 2014 and 2013 was recorded in our condensed consolidated balance sheets as property, plant and equipment of $36.7 million and $20.3 million, respectively, which represents the carrying value of the Exterran Holdings’ affiliates that sold it to us, and as a distribution of equity of $4.0 million and $2.2 million, respectively, which represents the fixed margin we paid above the carrying value in accordance with the Omnibus Agreement. During the three months ended March 31, 2014 and 2013, Exterran Holdings contributed to us $2.6 million and $6.2 million, respectively, primarily related to the completion of overhauls on compression equipment that was exchanged with us or contributed to us and where overhauls were in progress on the date of exchange or contribution.
	If Exterran Holdings determines in good faith that we or Exterran Holdings’ contract operations services business need to transfer, exchange or lease compression equipment between Exterran Holdings and us, the Omnibus Agreement permits such equipment to be transferred, exchanged or leased if it will not cause us to breach any existing contracts, suffer a loss of revenue under an existing compression services contract or incur any unreimbursed costs. In consideration for such transfer, exchange or lease of compression equipment, the transferee will either (1) transfer to the transferor compression equipment equal in value to the appraised value of the compression equipment transferred to it, (2) agree to lease such compression equipment from the transferor or (3) pay the transferor an amount in cash equal to the appraised value of the compression equipment transferred to it. These provisions will terminate on December 31, 2014 unless the Omnibus Agreement is terminated earlier as discussed above.
	During the three months ended March 31, 2014, pursuant to the terms of the Omnibus Agreement, we transferred ownership of 83 compressor units, totaling approximately 35,800 horsepower with a net book value of approximately $16.0 million, to Exterran Holdings. In exchange, Exterran Holdings transferred ownership of 84 compressor units, totaling approximately 28,200 horsepower with a net book value of approximately $15.1 million, to us. During the three months ended March 31, 2013, pursuant to the terms of the Omnibus Agreement, we transferred ownership of 43 compressor units, totaling approximately 20,900 horsepower with a net book value of approximately $9.1 million, to Exterran Holdings. In exchange, Exterran Holdings transferred ownership of 46 compressor units, totaling approximately 13,800 horsepower with a net book value of approximately $5.2 million, to us. During the three months ended March 31, 2014 and 2013, we recorded capital distributions of approximately $0.9 million and $3.9 million, respectively, related to the differences in net book value on the exchanged compression equipment. No customer contracts were included in the transfers. Under the terms of the Omnibus Agreement, such transfers must be of equal appraised value, as defined in the Omnibus Agreement, with any difference being settled in cash.
	At March 31, 2014, we had equipment on lease to Exterran Holdings with an aggregate cost and accumulated depreciation of $7.0 million and $3.3 million, respectively. During each of the three month periods ended March 31, 2014 and 2013, we had revenue of $0.1 million from Exterran Holdings related to the lease of our compression equipment. During the three months ended March 31, 2014 and 2013, we had cost of sales of $1.4 million and $2.1 million, respectively, with Exterran Holdings related to the lease of Exterran Holdings’ compression equipment.
	During the three months ended March 31, 2013, we sold compression equipment with a net book value of $1.3 million to Exterran Holdings for $3.4 million. Under GAAP, assets sales between entities under common control are to be initially recorded on the books of the receiving entity at the carrying value of the transferor. Any difference between consideration received and the carrying value of the assets sold is treated as a capital distribution or contribution. During the three months ended March 31, 2013, we recorded a capital contribution of $2.1 million related to the difference between the sales price and the carrying value of the compression equipment assets sold. During the three months ended March 31, 2014, we did not sell any compression equipment to Exterran Holdings.
	Exterran Holdings provides all operational staff, corporate staff and support services reasonably necessary to run our business. These services may include, without limitation, operations, marketing, maintenance and repair, periodic overhauls of compression equipment, inventory management, legal, accounting, treasury, insurance administration and claims processing, risk management, health, safety and environmental, information technology, human resources, credit, payroll, internal audit, taxes, facilities management, investor relations, enterprise resource planning system, training, executive, sales, business development and engineering.
	Exterran Holdings charges us for costs that are directly attributable to us. Costs that are indirectly attributable to us and Exterran Holdings’ other operations are allocated among Exterran Holdings’ other operations and us. The allocation methodologies vary based on the nature of the charge and include, among other things, revenue and horsepower. We believe that the allocation methodologies used to allocate indirect costs to us are reasonable.
	Under the Omnibus Agreement, our obligation to reimburse Exterran Holdings for any cost of sales that it incurs in the operation of our business and any cash SG&A expense allocated to us is capped (after taking into account any such costs we incur and pay directly) through December 31, 2014. Cost of sales was capped at $21.75 per operating horsepower per quarter through December 31, 2013, and is capped at $22.50 per operating horsepower per quarter from January 1, 2014 through December 31, 2014. SG&A costs were capped at $10.5 million per quarter through March 31, 2013 and at $12.5 million per quarter from April 1, 2013 through December 31, 2013, and are capped at $15.0 million per quarter from January 1, 2014 through April 9, 2014 and at $17.7 million per quarter from April 10, 2014 through December 31, 2014 (see Note 13). These caps may be subject to future adjustment or termination in connection with expansion of our operations through the acquisition or construction of new assets or businesses.
	Our cost of sales exceeded the cap provided in the Omnibus Agreement by $2.6 million and $3.5 million during the three months ended March 31, 2014 and 2013, respectively. Our SG&A expenses exceeded the cap provided in the Omnibus Agreement by $3.6 million and $1.9 million during the three months ended March 31, 2014 and 2013, respectively. The excess amounts over the caps are included in the condensed consolidated statements of operations as cost of sales or SG&A expense. The cash received for the amounts over the caps has been accounted for as a capital contribution in our condensed consolidated balance sheets and condensed consolidated statements of cash flows.

	Long-term debt	$	801,595	$	757,955
	In March 2013, we amended our senior secured credit agreement (the “Credit Agreement”) to reduce the borrowing capacity under our revolving credit facility by $100.0 million to $650.0 million and extend the maturity date of the term loan and revolving credit facilities to May 2018. As a result of the March 2013 amendment, we expensed $0.7 million of unamortized deferred financing costs, which is reflected in interest expense in our condensed consolidated statements of operations. During the three months ended March 31, 2013, we incurred transaction costs of approximately $4.3 million related to the amendment to our Credit Agreement. These costs were included in intangible and other assets, net, and are being amortized over the terms of the facilities. As of March 31, 2014, we had undrawn and available capacity of $343.5 million under our revolving credit facility.
	In March 2013, we issued $350.0 million aggregate principal amount of 6% senior notes due April 2021 (the “6% Notes”). We used the net proceeds of $336.9 million, after original issuance discount and issuance costs, to repay borrowings outstanding under our revolving credit facility. During the three months ended March 31, 2013, we incurred $7.6 million in transaction costs related to this issuance. These costs were included in intangible and other assets, net, and are being amortized to interest expense over the term of the 6% Notes. The 6% Notes were issued at an original issuance discount of $5.5 million, which is being amortized using the effective interest method at an interest rate of 6.25% over their term. In January 2014, holders of the 6% Notes exchanged their 6% Notes for registered notes with the same terms.
	The 6% Notes are guaranteed on a senior unsecured basis by all of our existing subsidiaries (other than EXLP Finance Corp., which is a co-issuer of the 6% Notes) and certain of our future subsidiaries. The 6% Notes and the guarantees, respectively, are our and the guarantors’ general unsecured senior obligations, rank equally in right of payment with all of our and the guarantors’ other senior obligations, and are effectively subordinated to all of our and the guarantors’ existing and future secured debt to the extent of the value of the collateral securing such indebtedness. In addition, the 6% Notes and guarantees are effectively subordinated to all existing and future indebtedness and other liabilities of any future non-guarantor subsidiaries. All of our subsidiaries are 100% owned, directly or indirectly, by us and guarantees by our subsidiaries are full and unconditional and constitute joint and several obligations. We have no assets or operations independent of our subsidiaries, and there are no significant restrictions upon our subsidiaries’ ability to distribute funds to us. EXLP Finance Corp. has no operations and does not have revenue other than as may be incidental as co-issuer of the 6% Notes. Because we have no independent operations, the guarantees are full and unconditional and constitute joint and several obligations of our subsidiaries other than EXLP Finance Corp., and as a result we have not included consolidated financial information of our subsidiaries.

Long-Term Incentive Plan (the “Plan”) in October 2006 for employees, directors and consultants of us, Exterran Holdings and our respective affiliates. A maximum of 1,035,378 common units, common unit options, restricted units and phantom units are available under the Plan. The Plan is administered by our board of directors or a committee thereof (the “Plan Administrator”).
	Phantom units are notional units that entitle the grantee to receive a common unit upon the vesting of the phantom unit or, at the discretion of the Plan Administrator, cash equal to the fair market value of a common unit. Certain phantom units granted under the Plan include nonforfeitable tandem distribution equivalent rights to receive cash distributions on unvested phantom units in the quarter in which distributions are paid on common units.

	7.  Accounting for Derivatives
	We are exposed to market risks associated with changes in interest rates. We use derivative financial instruments to minimize the risks and/or costs associated with financial activities by managing our exposure to interest rate fluctuations on a portion of our debt obligations. We do not use derivative financial instruments for trading or other speculative purposes.
	Interest Rate Risk
	At March 31, 2014, we were a party to interest rate swaps with a notional value of $250.0 million, pursuant to which we make fixed payments and receive floating payments. We entered into these swaps to offset changes in expected cash flows due to fluctuations in the associated variable interest rates. Our interest rate swaps expire in May 2018. As of March 31, 2014, the weighted average effective fixed interest rate on our interest rate swaps was 1.7%. We have designated these interest rate swaps as cash flow hedging instruments so that any change in their fair values is recognized as a component of comprehensive income (loss) and is included in accumulated other comprehensive income (loss) to the extent the hedge is effective. As the swap terms substantially coincide with the hedged item and are expected to offset changes in expected cash flows due to fluctuations in the variable rate, we currently do not expect a significant amount of ineffectiveness on these hedges. We perform quarterly calculations to determine whether the swap agreements are still effective and to calculate any ineffectiveness. There was no ineffectiveness related to interest rate swaps during the three months ended March 31, 2014 and 2013. We estimate that $3.8 million of deferred losses attributable to interest rate swaps and included in our accumulated other comprehensive income (loss) at March 31, 2014, will be reclassified into earnings as interest expense at then-current values during the next twelve months as the underlying hedged transactions occur. Cash flows from derivatives designated as hedges are classified in our condensed consolidated statements of cash flows under the same category as the cash flows from the underlying assets, liabilities or anticipated transactions, unless the derivative contract contains a significant financing element; in this case, the cash settlements for these derivatives are classified as cash flows from financing activities in our condensed consolidated statements of cash flows.
	In May 2013, we amended our interest rate swap agreements with a notional value of $250.0 million to adjust the fixed interest rates and extend the maturity dates to May 2018 consistent with the maturity date of our Credit Agreement. These amendments effectively created new derivative contracts and terminated the old derivative contracts. As a result, we designated the new hedge relationships under the amended terms and de-designated the original hedge relationships as of the termination date. The original hedge relationships qualified for hedge accounting and were included at their fair value in our balance sheet as a liability and accumulated other comprehensive income (loss). The fair value of the interest rate swap agreements immediately prior to the execution of the amendments was a liability of $8.8 million. The associated amount in accumulated other comprehensive income (loss) is being amortized into interest expense over the original terms of the swaps.

We have no specific collateral posted for our derivative instruments. The counterparties to our interest rate swaps are also lenders under our senior secured credit facility and, in that capacity, share proportionally in the collateral pledged under the related facility.

	The accounting standard for fair value measurements and disclosures establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into the following three broad categories:
	·                       Level 1 — Quoted unadjusted prices for identical instruments in active markets to which we have access at the date of measurement.
	·                       Level 2 — Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets. Level 2 inputs are those in markets for which there are few transactions, the prices are not current, little public information exists or prices vary substantially over time or among brokered market makers.
	·                      Level 3 — Model derived valuations in which one or more significant inputs or significant value drivers are unobservable. Unobservable inputs are those inputs that reflect our own assumptions regarding how market participants would price the asset or liability based on the best available information.

	During the three months ended March 31, 2014, we evaluated the future deployment of our idle fleet and determined to retire and either sell or re-utilize the key components of approximately 25 idle compressor units, representing approximately 7,000 horsepower, previously used to provide services. As a result, we performed an impairment review and recorded a $2.5 million asset impairment to reduce the book value of each unit to its estimated fair value. The fair value of each unit was estimated based on either the expected net sale proceeds compared to other fleet units we recently sold and/or a review of other units recently offered for sale by third parties, or the estimated component value of the equipment we plan to use.
	During the three months ended March 31, 2013, we evaluated the future deployment of our idle fleet and determined to retire and either sell or re-utilize the key components of approximately 40 idle compressor units, representing approximately 7,000 horsepower, previously used to provide services. As a result, we performed an impairment review and recorded a $1.5 million asset impairment to reduce the book value of each unit to its estimated fair value.

	In January 2014, Exterran Holdings announced a plan to centralize its make ready operations to improve the cost and efficiency of its shops and further enhance the competitiveness of our and Exterran Holdings’ combined U.S. compressor fleet. As part of this plan, Exterran Holdings examined both recent and anticipated changes in the U.S. market, including the throughput demand of its shops and the addition of new equipment to our and Exterran Holdings’ combined U.S. compressor fleet. To better align its costs and capabilities with the current market, Exterran Holdings has determined to close several of its make ready shops. The centralization of its make ready operations is expected to be completed by the middle of 2014.
	During the three months ended March 31, 2014, we incurred $0.4 million of restructuring charges comprised of an allocation of expenses, including termination benefits associated with the centralization of Exterran Holdings’ make ready operations, from Exterran Holdings to us pursuant to the terms of the Omnibus Agreement based on revenue and horsepower. These charges are reflected as restructuring charges in our condensed consolidated statements of operations. We currently estimate that we will incur additional charges allocated to us with respect to the centralization of Exterran Holdings’ make ready operations of approximately $0.4 million. The estimated additional charges will result in payables to Exterran Holdings.

	In 2011, the Texas Legislature enacted changes related to the appraisal of natural gas compressors for ad valorem tax purposes by expanding the definitions of “Heavy Equipment Dealer” and “Heavy Equipment” effective from the beginning of 2012 (the “Heavy Equipment Statutes”). Under the revised statutes, we believe we are a Heavy Equipment Dealer, that our natural gas compressors are Heavy Equipment and that we, therefore, are required to file our ad valorem tax renditions under this new methodology. A large number of appraisal review boards denied our position, and we filed petitions for review in the appropriate district courts.
	During 2013 and the first quarter of 2014, we were party to three Heavy Equipment Statutes cases tried and completed in Texas state district courts. In each case the court held that the revised Heavy Equipment Statutes apply to natural gas compressors. However, in each case the court further held that the revised Heavy Equipment Statutes are unconstitutional as applied to natural gas compressors, which is favorable to the county appraisal districts. We continue to believe that the revised statutes are constitutional as applied to natural gas compressors and have appealed the courts’ decisions in our cases. In addition, we have filed motions for summary judgment in two other state district court cases but have yet to receive the courts’ decisions.
	As a result of the new methodology, our ad valorem tax expense (which is reflected on our condensed consolidated statements of operations as a component of cost of sales (excluding depreciation and amortization expense)) includes a benefit of $1.8 million during the three months ended March 31, 2014. Since the change in methodology became effective in 2012, we have recorded an aggregate benefit of $12.3 million as of March 31, 2014, of which approximately $2.1 million has been agreed to by a number of appraisal review boards and county appraisal districts and $10.2 million has been disputed and is currently in litigation. Recognizing the similarity of the issues and that these cases will ultimately be resolved by the Texas appellate courts, we have reached, or intend to reach, agreements with appraisal districts to stay or abate other pending district court cases. If we are unsuccessful in any of the cases with the appraisal districts, we would be required to pay ad valorem taxes up to the aggregate benefit we have recorded, and the additional ad valorem tax payments may also be subject to penalties and interest. In addition, if we are unsuccessful in any of the cases with the appraisal districts, we would likely be required to pay the ad valorem taxes under the old methodology going forward, which would increase our quarterly cost of sales expense up to approximately the amount of our then most recent quarterly benefit recorded, and as a result impact our future results of operations and cash flows, including our cash available for distribution.
	In the ordinary course of business, we are also involved in various other pending or threatened legal actions. While management is unable to predict the ultimate outcome of these actions, it believes that any ultimate liability arising from any of these other actions will not have a material adverse effect on our consolidated financial position, results of operations or cash flows, including our ability to make cash distributions to our unitholders. However, because of the inherent uncertainty of litigation and arbitration proceedings, we cannot provide assurance that the resolution of any particular claim or proceeding to which we are a party will not have a material adverse effect on our consolidated financial position, results of operations or cash flows, including our ability to make cash distributions to our unitholders.
	We are subject to a number of state and local taxes that are not income-based. As many of these taxes are subject to audit by the taxing authorities, it is possible that an audit could result in additional taxes due. We accrue for such additional taxes when we determine that it is probable that we have incurred a liability and we can reasonably estimate the amount of the liability. As of March 31, 2014 and December 31, 2013, we have accrued $3.9 million and $4.7 million, respectively, for the outcomes of non-income based tax audits. We do not expect that the ultimate resolutions of these audits will result in a material variance from the amounts accrued. We do not accrue for unasserted claims for tax audits unless we believe the assertion of a claim is probable, it is probable that it will be determined that the claim is owed and we can reasonably estimate the claim or range of the claim. We do not have any unasserted claims from non-income based tax audits that we have determined are probable of assertion. We also believe the likelihood is remote that the impact of potential unasserted claims from non-income based tax audits could be material to our consolidated financial position, but it is possible that the resolution of future audits could be material to our results of operations or cash flows for the period in which the resolution occurs.

	On April 2, 2014, we sold, pursuant to a public underwritten offering, 6,210,000 common units, including 810,000 common units pursuant to an over-allotment option. We received net proceeds of $169.5 million, after deducting underwriting discounts, commissions and offering expenses, which we used to fund a portion of the April 2014 MidCon Acquisition. In connection with this sale and as permitted under our partnership agreement, we issued and sold approximately 126,000 general partner units to our general partner so it could maintain its approximate 2.0% general partner interest in us. We received net proceeds of $3.6 million from the general partner contribution which we used to repay borrowings outstanding under our revolving credit facility.
	On April 7, 2014, we issued $350.0 million aggregate principal amount of 6% senior notes due October 2022 (the “2014 Notes”). We received net proceeds of $337.4 million, after original issuance discount and issuance costs, from this offering, which we used to fund a portion of the April 2014 MidCon Acquisition and repay borrowings under our revolving credit facility. The 2014 Notes were issued at an original issuance discount of $5.7 million, which will be amortized using the effective interest method at an interest rate of 6.25% over their term. We incurred $6.9 million in transaction costs related to this issuance. These costs will be included in intangible and other assets, net, and amortized to interest expense over the term of the 2014 Notes. The 2014 Notes have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or any state securities laws, and unless so registered, may not be offered or sold in the U.S. except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and applicable state securities laws. We offered and issued the 2014 Notes only to qualified institutional buyers pursuant to Rule 144A under the Securities Act and to persons outside the U.S. pursuant to Regulation S. Pursuant to a registration rights agreement, we are required to register the 2014 Notes no later than 365 days after April 7, 2014.
	The 2014 Notes are guaranteed on a senior unsecured basis by all of our existing subsidiaries (other than EXLP Finance Corp., which is a co-issuer of the 2014 Notes) and certain of our future subsidiaries. The 2014 Notes and the guarantees, respectively, are our and the guarantors’ general unsecured senior obligations, rank equally in right of payment with all of our and the guarantors’ other senior obligations, and are effectively subordinated to all of our and the guarantors’ existing and future secured debt to the extent of the value of the collateral securing such indebtedness. In addition, the 2014 Notes and guarantees are effectively subordinated to all existing and future indebtedness and other liabilities of any future non-guarantor subsidiaries. All of our subsidiaries are 100% owned, directly or indirectly, by us and guarantees by our subsidiaries are full and unconditional and constitute joint and several obligations. We have no assets or operations independent of our subsidiaries, and there are no significant restrictions upon our subsidiaries’ ability to distribute funds to us. EXLP Finance Corp. has no operations and does not have revenue other than as may be incidental as co-issuer of the 2014 Notes.
	On April 10, 2014, we completed the April 2014 MidCon Acquisition for total cash consideration of $362.8 million, of which a wholly-owned subsidiary of Exterran Holdings that is our indirect parent company paid $9.4 million for specified assets. See Note 2 for further discussion of this acquisition. In connection with the April 2014 MidCon Acquisition, the Omnibus Agreement was amended to increase the cap on SG&A expenses from $15.0 million per quarter to $17.7 million per quarter from April 10, 2014 through December 31, 2014.

Comprehensive Income (Loss)	'
	Comprehensive Income (Loss)
	Components of comprehensive income (loss) are net income (loss) and all changes in equity during a period except those resulting from transactions with our limited partners or general partner. Our accumulated other comprehensive income (loss) consists only of derivative financial instruments. Changes in accumulated other comprehensive income (loss) represent changes in the fair value of derivative financial instruments that are designated as cash flow hedges and to the extent the hedge is effective and the amortization of terminated interest rate swaps. See Note 7 for additional disclosures related to comprehensive income (loss).
Financial Instruments	'
	Financial Instruments
	Our financial instruments consist of cash, escrow deposit, trade receivables, interest rate swaps and debt. At March 31, 2014 and December 31, 2013, the estimated fair values of these financial instruments approximated their carrying amounts as reflected in our condensed consolidated balance sheets. The fair value of our fixed rate debt was estimated based on quoted market yields in inactive markets, which are Level 2 inputs. The fair value of our floating rate debt was estimated using a discounted cash flow analysis based on interest rates offered on loans with similar terms to borrowers of similar credit quality, which are Level 3 inputs. See Note 8 for additional information regarding the fair value hierarchy.
	The following table summarizes the carrying amount and fair value of our debt as of March 31, 2014 and December 31, 2013 (in thousands):
		March 31, 2014					December 31, 2013
		Carrying			Fair Value		Carrying		Fair Value
		Amount					Amount
	Fixed rate debt	$	345,095		$	350,000	$	344,955	$	346,000
	Floating rate debt	456,500			457,000		413,000		413,000
	Total debt	$	801,595		$	807,000	$	757,955	$	759,000
	GAAP requires that all derivative instruments (including certain derivative instruments embedded in other contracts) be recognized in the balance sheet at fair value and that changes in such fair values be recognized in earnings (loss) unless specific hedging criteria are met. Changes in the values of derivatives that meet these hedging criteria will ultimately offset related earnings effects of the hedged item pending recognition in earnings.
Earnings (Loss) Per Common Unit	'
	Earnings (Loss) Per Common Unit
	The computation of earnings (loss) per common unit is based on the weighted average number of common units (also referred to as limited partner units) outstanding during the applicable period. Basic earnings (loss) per common unit is determined by dividing net income (loss) allocated to the common units after deducting the amount allocated to our general partner (including distributions to our general partner on its incentive distribution rights) by the weighted average number of outstanding common units during the period.
	When computing earnings per common unit in periods when distributions are greater than earnings (loss), the amount of the incentive distribution rights, if any, is deducted from net income (loss) and allocated to our general partner for the corresponding period. The remaining amount of net income (loss), after deducting the incentive distribution rights, is allocated between the general partner and common units based on how our partnership agreement allocates net losses.
	When computing earnings (loss) per common unit in periods when earnings (loss) are greater than distributions, earnings are allocated to the general partner and common units based on how our partnership agreement would allocate earnings if the full amount of earnings for the period had been distributed. This allocation of net income (loss) does not impact our total net income (loss), consolidated results of operations or total cash distributions; however, it may result in our general partner being allocated additional incentive distributions for purposes of our earnings (loss) per unit calculation, which could reduce net income per common unit. However, as required by our partnership agreement, we determine cash distributions based on available cash and determine the actual incentive distributions allocable to our general partner based on actual distributions.
	The potentially dilutive securities issued by us include phantom units, which do not require an adjustment to the amount of net income (loss) used for computing dilutive earnings per common unit. The following table shows the potential common units that were included in computing diluted earnings (loss) per common unit (in thousands):
