Purchase Agreement

On March 22, 2013, Exterran Partners, L.P. (“we”) and our subsidiary, EXLP Finance Corp., as co-issuers, and certain of our subsidiaries, as guarantors (the “Guarantors”), entered into a Purchase Agreement (the “Purchase Agreement”) with Wells Fargo Securities, LLC, as representative of the initial purchasers named therein (the “Initial Purchasers”), pursuant to which we agreed to sell $350.0 million in aggregate principal amount of 6% Senior Notes due 2021 (the “Notes”). The 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 United States 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 will issue the Notes only to qualified institutional buyers pursuant to Rule 144A under the Securities Act and to persons outside the United States pursuant to Regulation S. The information contained in this Current Report on Form 8-K, including the exhibits, shall not constitute an offer to sell or the solicitation of an offer to buy the Notes nor shall there be any sale of the Notes in any state in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state.

The Purchase Agreement contains customary representations and warranties of the parties and indemnification and contribution provisions under which we, EXLP Finance Corp. and the Guarantors, on one hand, and the Initial Purchasers, on the other, have agreed to indemnify each other against certain liabilities, including liabilities under the Securities Act. In addition, the Purchase Agreement requires the execution of a registration rights agreement, described below, relating to the Notes.

We used the net proceeds of this offering of approximately $336 million (after deducting discounts, commissions and estimated offering expenses), to repay outstanding indebtedness under our revolving senior secured credit facility.

The foregoing summary of the Purchase Agreement is qualified in its entirety by reference to the full text of the Purchase Agreement, which is filed as Exhibit 1.1 to this Current Report on Form 8-K and is incorporated herein by reference.

Indenture

On March 27, 2013, we entered into an Indenture (the “Indenture”), by and among us, EXLP Finance Corp., the Guarantors and Wells Fargo Bank, National Association, as trustee (the “Trustee”), in connection with the private placement of the Notes. On March 27, 2013, we issued the Notes pursuant to the Indenture in a transaction exempt from registration requirements under the Securities Act. The Notes were resold to qualified institutional buyers pursuant to Rule 144A under the Securities Act and to persons outside the United States pursuant to Regulation S under the Securities Act. The Notes will mature on April 1, 2021. The interest payment dates are April 1 and October 1 of each year, beginning on October 1, 2013.

Prior to April 1, 2017, we may redeem all or a part of the Notes at a redemption price equal to the sum of (i) the principal amount thereof, plus (ii) a make-whole premium at the redemption date, plus accrued and unpaid interest, if any, to the redemption date. In addition, we may redeem up to 35% of the aggregate principal amount of the Notes prior to April 1, 2016 with the net proceeds of one or more equity offerings at a redemption price of 106.000% of the principal amount of the Notes, plus any accrued and unpaid interest to the date of redemption, if at least 65% of the aggregate principal amount of the Notes issued under the Indenture remains outstanding after such redemption and the redemption occurs within 180 days of the date of the closing of such equity offering. On or after April 1, 2017, we may redeem all or a part of the Notes at redemption prices (expressed as percentages of principal amount) equal to 103.000% for the twelve-month period beginning on April 1, 2017, 101.500% for the twelve-month period beginning on April 1, 2018 and 100.000% for the twelve-month period beginning on April 1, 2019 and at any time thereafter, plus accrued and unpaid interest, if any, to the applicable redemption date on the Notes.

The Indenture contains customary covenants that restrict our ability and the ability of certain of our subsidiaries to: (i) pay distributions on, repurchase or redeem our units or repurchase or redeem our subordinated debt; (ii) make investments; (iii) incur or guarantee additional indebtedness or issue preferred units; (iv) create or incur certain liens; (v) sell assets; (vi) consolidate, merge or transfer all or substantially all of our assets; (vii) enter into agreements that restrict distributions or other payments from our restricted subsidiaries to us; (viii) engage in transactions with affiliates; and (ix) create unrestricted subsidiaries. These covenants are subject to a number of

2

important exceptions and qualifications. If the Notes achieve an investment grade rating from each of Moody’s Investors Service, Inc. and Standard & Poor’s Ratings Services and no Default (as defined in the Indenture) has occurred and is continuing, many of these covenants will terminate.

The Indenture also contains customary Events of Defaults. Each of the following is an Event of Default: (i) default for 30 days in the payment when due of interest or special interest, if any, on the Notes; (ii) default in payment when due of the principal of, or premium, if any, on the Notes; (iii) our failure to comply with certain covenants relating to asset sales, repurchases of the Notes, merger or consolidation; (iv) our failure for 180 days after notice to comply with our reporting obligations under the Securities Exchange Act of 1934; (v) our failure for 60 days after notice to comply with any of the other agreements in the Indenture; (vi) default under any mortgage, indenture or instrument governing any indebtedness for money borrowed or guaranteed by us or any of our restricted subsidiaries, whether such indebtedness or guarantee now exists or is created after the date of the Indenture, if such default: (a) is caused by a payment default; or (b) results in the acceleration of such indebtedness prior to its stated maturity, and, in each case, the principal amount of the indebtedness, together with the principal amount of any other such indebtedness under which there has been a payment default or acceleration of maturity, aggregates $25.0 million or more, subject to a cure provision; (vii) our failure or any of our restricted subsidiaries’ failure to pay final judgments aggregating in excess of $25.0 million (to the extent not covered by insurance), which judgments are not paid, discharged or stayed for a period of 60 days; (viii) except as permitted by the Indenture, any subsidiary guarantee is held in any judicial proceeding to be unenforceable or invalid or ceases for any reason to be in full force or effect, or any Guarantor, or any person acting on behalf of any Guarantor, denies or disaffirms its obligations under its subsidiary guarantee; and (ix) certain events of bankruptcy, insolvency or reorganization described in the Indenture with respect to us or any of our restricted subsidiaries that is a significant subsidiary or any group of restricted subsidiaries that, taken together, would constitute a significant subsidiary. Upon a continuing Event of Default, the Trustee, by notice to us, or the holders of at least 25% in principal amount of the then outstanding Notes, by notice to us and the Trustee, may declare the Notes immediately due and payable, except that an Event of Default resulting from entry into a bankruptcy, insolvency or reorganization with respect to us, EXLP Finance Corp., any restricted subsidiary that is a significant subsidiary or any group of restricted subsidiaries that, taken together, would constitute a significant subsidiary, will automatically cause the Notes to become due and payable.

The foregoing summary of the Indenture is qualified in its entirety by reference to the full text of the Indenture, which is filed as Exhibit 4.1 to this Current Report on Form 8-K and is incorporated herein by reference.

Registration Rights Agreement

On March 27, 2013, we entered into a Registration Rights Agreement (the “Registration Rights Agreement”) with EXLP Finance Corp., the Guarantors and Wells Fargo Securities, LLC, as representative of the Initial Purchasers, in connection with the private placement of the Notes.

Under the Registration Rights Agreement, we will cause to be filed with the Securities and Exchange Commission a registration statement with respect to an offer to exchange the Notes and the related guarantees for substantially identical notes and guarantees that are registered under the Securities Act. We will use our commercially reasonable efforts to cause such exchange offer registration statement to become effective under the Securities Act. In addition, we will use our commercially reasonable efforts to cause the exchange offer to be consummated not later than 365 days after March 27, 2013. Under some circumstances, in lieu of, or in addition to, a registered exchange offer, we have agreed to file a shelf registration statement with respect to the Notes and guarantees. We are required to pay additional interest if we fail to comply with our obligations to register the Notes and guarantees within the specified time periods.

The foregoing summary of the Registration Rights Agreement is qualified in its entirety by reference to the full text of the Registration Rights Agreement, which is filed as Exhibit 4.2 to this Current Report on Form 8-K and is incorporated herein by reference.

Third Amendment to Amended and Restated Senior Secured Credit Agreement

On March 27, 2013, we, as Guarantor, and EXLP Operating LLC (“EXLP Operating”), our wholly owned subsidiary, as Borrower, entered into the Third Amendment to Amended and Restated Senior Secured Credit Agreement (the “Credit Agreement Amendment”) with Wells Fargo Bank, National Association, as Administrative Agent, and the other lenders signatory thereto. The Credit Agreement Amendment amends the Amended and Restated Senior Secured Credit Agreement, dated as of November 3, 2010, as subsequently amended (as amended, the “Credit Agreement”), among us, EXLP Operating, Wells Fargo Bank, National Association, as Administrative Agent, Bank of America, N.A. and

3

JPMorgan Chase Bank, N.A., as Co-Syndication Agents, Barclays Bank plc and The Royal Bank of Scotland plc, as Co-Documentation Agents, and the other lenders signatory thereto, in order to, among other things, (i) extend the maturity date of the credit facility to May 15, 2018 and (ii) reduce the aggregate borrowing capacity under the revolving credit facility by $100 million. The Credit Agreement now provides for a $650 million revolving credit facility (with a $50 million sublimit for letters of credit and a $50 million sublimit for swingline loans) and a $150 million term loan facility.

The foregoing summary of the Credit Agreement Amendment is qualified in its entirety by reference to the full text of the Credit Agreement Amendment, which is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.

Relationships

An affiliate of Wells Fargo Securities, LLC, one of the Initial Purchasers, is the trustee for the Notes and the Administrative Agent under the Credit Agreement. Many of the Initial Purchasers or their affiliates are lenders under our credit facility and, in that capacity, will receive a portion of the proceeds from the offering. Some of the Initial Purchasers and their affiliates have engaged in, and may in the future engage in, investment banking and other commercial dealings in the ordinary course of business with us or our affiliates. They have received, or may in the future receive, customary fees and commissions for these transactions.
