Item 1.01.                Entry into a Material Definitive Agreement.

Indenture

On March 23, 2018, in connection with the previously announced offering by USA Compression Partners, LP, a Delaware limited partnership (the “Partnership”), and its wholly-owned subsidiary, USA Compression Finance Corp., a Delaware corporation (“Finance Corp.” and, together with the Partnership, the “Issuers”) of $725 million in aggregate principal amount of the Issuers’ 6.875% senior notes due 2026 (the “Notes”), the Partnership entered into an Indenture (the “Indenture”), among the Issuers, the Guarantors (as defined below) and Wells Fargo Bank, National Association, as trustee. The Notes are guaranteed (the “Guarantees”), jointly and severally, on a senior unsecured basis by the Partnership’s existing subsidiaries (other than Finance Corp.) and each of its future restricted subsidiaries that either borrows under, or guarantees, the Partnership’s senior secured asset-based revolving credit facility or guarantees certain of the Partnership’s other indebtedness (collectively, the “Guarantors”).

On March 23, 2018, the Notes were issued pursuant to the Indenture in a transaction exempt from the registration requirements under the Securities Act of 1933, as amended (the “Securities Act”). The Notes will be resold within the United States only to persons reasonably believed to be qualified institutional buyers in reliance on Rule 144A under the Securities Act, and outside the United States only to non-U.S. persons in reliance on Regulation S under the Securities Act. The Notes will accrue interest from March 23, 2018 at the rate of 6.875% per year. Interest on the Notes will be payable semi-annually in arrears on each April 1 and October 1, commencing on October 1, 2018.

The net proceeds from the issuance and sale of the Notes and the Guarantees, together with the net proceeds from a private placement of preferred units of the Partnership and borrowings under its asset-based revolving credit facility, will be used to fund the cash purchase price of the Partnership’s previously announced acquisition of all of the issued and outstanding membership interests in CDM Resource Management LLC and CDM Environmental & Technical Services LLC from Energy Transfer Partners, L.P. (the “CDM Acquisition”). If the CDM Acquisition is not completed on or prior to April 30, 2018 or, if prior to such date, the contribution agreement providing for the CDM Acquisition is terminated, the Notes will be subject to a special mandatory redemption at a redemption price payable in cash equal to 100.0% of the initial issue price of the Notes, plus accrued and unpaid interest to, but excluding, the date of redemption.

The Indenture contains customary terms, events of default and covenants relating to, among other things, the incurrence of debt, the payment of distributions or similar restricted payments, undertaking transactions with affiliates and limitations on asset sales.

At any time prior to April 1, 2021, the Issuers may redeem up to 35% of the aggregate principal amount of the Notes at a redemption price equal to 106.875% of the principal amount redeemed, plus accrued and unpaid interest, if any, to the redemption date, in an amount not greater than the net proceeds from one or more equity offerings, provided that at least 65% of the aggregate principal amount of the Notes remain outstanding immediately after the occurrence of such redemption (excluding Notes held by the Partnership and its subsidiaries) and redemption occurs within 180 days of the date of the closing of such equity offering. At any time prior to April 1, 2021, the Issuers may redeem the Notes, in whole or in part, at a redemption price equal to sum of the principal amount of the Notes plus a “make-whole” premium, plus accrued and unpaid interest, if any, to the redemption date. The Issuers may also redeem all or a part of the Notes at any time on or after April 1, 2021, at the redemption prices set forth in the Indenture, plus accrued and unpaid interest, if any, to the redemption date. If the Issuers experience a change of control followed by a ratings decline, unless the Issuers have previously exercised or concurrently exercise the right to redeem the Notes (as described above), the Issuers may be required to offer to repurchase the Notes at a purchase price equal to 101% of the principal amount repurchased, plus accrued and unpaid interest, if any, to the repurchase date.

The Notes and the Guarantees are the general unsecured obligations of the Issuers and the Guarantors and rank equally in right of payment with all of the Issuers’ and the Guarantors’ existing and future senior indebtedness and senior to all of the Issuers’ and the Guarantors’ future subordinated indebtedness, if any. The Notes and the Guarantees are effectively subordinated in right of payment to all of the Issuers’ and the Guarantors’ existing and

2

future secured debt, including debt under the Partnership’s senior secured credit facilities and guarantees thereof, to the extent of the value of the assets securing such debt, and are structurally subordinated to all indebtedness of any of the Partnership’s subsidiaries that do not guarantee the Notes.

The summary of the Indenture set forth in this Item 1.01 does not purport to be complete and is qualified by reference to such agreement, a copy of which is being filed as Exhibit 4.1 hereto and is incorporated herein by reference.

Registration Rights Agreement

Also on March 23, 2018, in connection with the closing of the Offering, the Issuers and each of the Guarantors entered into a Registration Rights Agreement (the “Registration Rights Agreement”) with J.P. Morgan Securities LLC and Barclays Capital Inc., as representatives of the initial purchasers named therein, pursuant to which the Issuers and Guarantors agreed (a) (i) to file with the Securities and Exchange Commission a registration statement (the “Exchange Offer Registration Statement”) on an appropriate form under the Securities Act, with respect to a registered offer to exchange any and all of the Notes (including the Guarantees) for a like aggregate principal amount of registered notes that are identical in all material respects to the Notes (except that the exchange notes will not be subject to restrictions on transfer or to any increase in annual interest rate for failure to comply with the Registration Rights Agreement ) and/or (ii) under certain circumstances set forth in the Registration Rights Agreement, a shelf registration statement pursuant to Rule 415 under the Securities Act (the “Shelf Registration Statement”) relating to the resale by certain holders of the Notes and the Guarantees thereof, (b) to use their reasonable best efforts to cause the (i) Exchange Offer Registration Statement to become effective under the Securities Act and remain effective until 180 days following the last Exchange Date (as defined in the Registration Rights Agreement) or (ii) if applicable, the Shelf Registration Statement to become and remain effective under the Securities Act until the Notes cease to be Registrable Securities (as defined in the Registration Rights Agreement), and (c) to use their reasonable best efforts to complete the exchange offer not later than 60 days after the date on which the Exchange Offer Registration Statement is declared effective. If the Issuers fail to comply with certain obligations under the Registration Rights Agreement, including if the exchange offer is not completed or if the Shelf Registration Statement is not declared effective by March 23, 2019, the interest rate borne by the Notes will be increased by 0.25% per annum (which rate will be increased by an additional 0.25% per annum for each subsequent 90-day period that such additional interest continues to accrue, provided that the rate at which such additional interest accrues may in no event exceed 1.00% per annum), commencing on the 365th day following issuance of the Notes until the exchange offer is completed or the Shelf Registration Statement is declared effective (or becomes automatically effective or is no longer required to be effective) in accordance with the provisions of the Registration Rights Agreement.

The summary of the Registration Rights Agreement set forth in this Item 1.01 does not purport to be complete and is qualified by reference to such agreement, a copy of which is being filed as Exhibit 4.3 hereto and is incorporated herein by reference.

WHEREAS, the Issuers have duly authorized the issue of 6.875% Senior Notes due 2026 (as they may be issued from time to time under this Indenture, including any Additional Notes issued pursuant to Section 1.03 of this Indenture, the “Notes”), initially in an aggregate principal amount not to exceed $725,000,000, and in connection therewith, the Issuers and the Initial Guarantors have duly determined to make, execute and deliver this Indenture to set forth the terms and provisions of the Notes;

WHEREAS, all things necessary to make the Notes, when executed by the Issuers and authenticated and delivered by the Trustee or a duly authorized authenticating agent and to make the Subsidiary Guarantees of each of the Guarantors as set forth herein, when the Notes have been so executed, authenticated and delivered, the valid and legally binding obligations of the Issuers and the Guarantors, respectively, have been done; and

WHEREAS, all things necessary to make this Indenture a valid and legally binding agreement according to its terms, have been done.

NOW, THEREFORE, the Issuers, the Guarantors and the Trustee agree as follows for the benefit of each other and for the equal and ratable benefit of the Holders of the Notes:

(a) The Notes shall be designated as the “6.875% Senior Notes due 2026.” The aggregate principal amount of Notes that may be authenticated and delivered under this Indenture is not limited. The aggregate principal amount of Notes initially authorized for authentication and delivery pursuant to this Indenture is limited to $725,000,000 (except for Notes authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of other Notes pursuant to Section 1.07, Section 1.08, Section 1.09, Section 3.06, Section 3.09, Section 4.15 and Section 8.05 hereof). The Issuers may, and shall be entitled to, from time to time, without notice to or the consent of the Holders of the Notes, in accordance with Section 1.03 below, increase the principal amount of Notes and issue such increased principal amount (or any portion thereof) of Notes as “Additional Notes” under this Indenture.

(b)                                 Payments of the principal of and interest on the Notes shall be made in U.S. dollars, and the Notes shall be denominated in U.S. dollars and in minimum amounts of at least

$2,000 and integral multiples of $1,000 in excess of $2,000. The Place of Payment where the principal of and any other payments due on the Notes are payable shall initially be at the office or agency of the Issuers maintained for that purpose in accordance with Section 4.02 of this Indenture.

(c)                                  The Company will maintain an office or agency where Notes may be presented for registration of transfer or for exchange (“Registrar”) and an office or agency where Notes may be presented for payment (“Paying Agent”). Initially, the Trustee will act as Paying Agent and Registrar. The Issuers may appoint and change any Paying Agent or Registrar or co-registrar without notice. The Company or any of its domestically organized wholly owned Restricted Subsidiaries may act as Paying Agent or Registrar or co-registrar.

(d)                                 All payments of principal, premium, if any, and interest due on all Global Notes will be made by wire transfer of immediately available funds to the accounts specified by the Holder or Holders thereof. Principal of, premium, if any, and interest on Notes in certificated form will be payable at the office or agency of the Issuers maintained for such purpose or, at the option of the Issuers, payment of interest may be made by check mailed to the Holders of the Notes at their respective addresses set forth in the register of Holders, except that if a Holder of at least $5.0 million principal amount of Notes has given wire transfer instructions to the Issuers to an account in the continental United States, the Issuers will pay all principal, interest and premium, if any, on that Holder’s Notes in accordance with those instructions. Until otherwise designated by the Issuers, the Issuers’ office or agency will be the office of the Trustee maintained for such purpose. Notwithstanding the foregoing, payment may be made pursuant to the Applicable Procedures of the Depository in the case of Global Notes.

(e)                                  The Notes shall be guaranteed by each of the Initial Guarantors and any additional Subsidiary Guarantors in accordance with Section 4.13 and Article Nine of this Indenture.

Section 1.02     Form of Notes. (a) The Notes shall be substantially in the form set forth in Exhibit A hereto, which is incorporated in and made a part of this Indenture.

(b)                                 Any of the Notes may have such letters, numbers or other marks of identification and such notations, legends or endorsements as the officers executing the same may approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of this Indenture or as may be required to comply with any law or with any rule or regulation made pursuant thereto or with any rule or regulation of any securities exchange or automated quotation system on which the Notes may be listed or designated for issuance, or to conform to usage or to indicate any special limitations or restrictions to which any particular Notes are subject.

(c)                                  The terms and provisions contained in the form of Note attached as Exhibit A hereto shall constitute, and are hereby expressly made, a part of this Indenture and, to the extent applicable, the Issuers and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby.

Section 1.03     Additional Notes.

(a)                                 The Issuers shall be entitled, subject to their compliance with Section 4.09, to issue Additional Notes under this Indenture which shall have identical terms as the Initial Notes issued on the Issue Date, other than with respect to the date of issuance, issue price, the date from which interest begins to accrue, applicable transfer restrictions and whether or not Section 3.10 shall apply with respect to such Additional Notes. The Initial Notes issued on the Issue Date and any Additional Notes shall be treated as a single class for all purposes under this Indenture, including waivers, consents, directions, declarations, amendments, redemptions and offers to purchase; and none of the Holders of any Initial Notes or any Additional Notes shall have the right to vote or consent as a separate class on any matter to which such Holders are entitled to vote or consent.

(b)                                 With respect to any Additional Notes, the Issuers shall set forth in an Issuer Order, which shall be delivered to the Trustee, the following information:

(1)                                 the aggregate principal amount of such Additional Notes to be authenticated and delivered pursuant to this Indenture;

(2)                                 the issue price, the issue date and the CUSIP number and any corresponding ISIN of such Additional Notes;

(3)                                 if applicable, that such Additional Notes shall be issuable in whole or in part in the form of one or more Global Notes and, in such case, the respective depositaries for such Global Notes, the form of any legend or legends which shall be borne by such Global Notes in addition to or in lieu of those set forth in Exhibit A hereto and any circumstances in addition to or in lieu of those set forth in Exhibit A in which any such Global Notes may be exchanged in whole or in part for Additional Notes registered, or any transfer of such Global Note in whole or in part may be registered, in the name or names of Persons other than the depositary for such Global Note or a nominee thereof.

Section 1.04     Execution and Authentication. (a) At least one Officer must sign the Notes for each of the Company and Finance Corp. by manual or facsimile signature. If an Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note will nevertheless be valid. A Note will not be valid until authenticated by the manual signature of the Trustee. The signature will be conclusive evidence that the Note has been authenticated under this Indenture.

(b)                                 The Trustee will, upon receipt of an Issuer Order, authenticate Notes for original issue that may be validly issued under this Indenture, including any Additional Notes. The Issuer Order shall specify the principal amount of the Notes to be authenticated and the date on which the original issue of such Notes is to be authenticated. The aggregate principal amount of Notes outstanding at any time may not exceed the aggregate principal amount of Notes authorized for issuance by the Company pursuant to one or more Issuer Orders, except as provided in Section 1.09. The Trustee may appoint an authenticating agent acceptable to the Company to authenticate the Notes. An authenticating agent may authenticate Notes whenever the Trustee

3

may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with Holders or an Affiliate of the Company.

Section 1.05     Non-Business Day Payments. If any Interest Payment Date, the Stated Maturity, any redemption date, any Settlement Date or any Change of Control Payment Date falls on a day that is not a Business Day, then the required payment or delivery will be made on the next succeeding Business Day with the same force and effect as if made on the date that the payment or delivery was due, and no additional interest will accrue on that required payment or delivery for the period from and after the Interest Payment Date, Stated Maturity, Redemption Date, Settlement Date or Change of Control Payment Date, as the case may be, to that next succeeding Business Day.

Section 1.06     Defaulted Interest. (a) Interest on any Note which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Notes is registered at the close of business on the Regular Record Date for such interest (or, if no business is conducted by the Trustee at its Corporate Trust Office on such date, at 5:00 P.M. New York City time on such date).

(b)                                 Any interest on the Notes which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date after giving effect to any applicable grace period (herein called “Defaulted Interest”) shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Issuers, at its election in each case, as provided in clause (1) or (2) below:

(1)                                 The Issuers may elect to make payment of any Defaulted Interest payable on any Notes to the Persons in whose names such Notes are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Issuers shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each of such Notes and the date of the proposed payment, and at the same time the Issuers shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon, the Issuers shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Issuers shall promptly notify the Trustee of such Special Record Date and, the Trustee, in the name and at the expense of the Issuers, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be given to each Holder of such Notes in the manner set forth in Section 1.10, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so sent, such Defaulted Interest shall be paid to the Persons in whose names such Notes are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (2).

4

(2)                                 The Issuers may make payment of any Defaulted Interest on any Notes in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Notes may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Issuers to the Trustee of the proposed payment pursuant to this Clause, such manner of payment shall be deemed practicable by the Trustee.

(c)                                  Except as may otherwise be provided in this Section 1.06, the Person to whom Defaulted Interest shall be payable on any Note that first becomes payable on a day that is not an Interest Payment Date shall be the Holder of such Note on the day such interest is paid.

(d)                                 Subject to the foregoing provisions of this Section 1.06, each Note delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Note.

(e)                                  The Trustee will have no duty whatsoever to determine whether any Defaulted Interest is payable or the amount thereof.

Section 1.07     Temporary Notes. (a) Pending the preparation of Definitive Notes, the Issuers may execute, and upon Issuer Order, the Trustee shall authenticate and deliver, temporary Notes which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the Definitive Notes in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Notes, respectively, may determine, as evidenced by their execution of such Notes, respectively.

(b)                                 If temporary Notes are issued, the Issuers will cause Definitive Notes to be prepared without unreasonable delay. After the preparation of Definitive Notes, the temporary Notes shall be exchangeable for Definitive Notes upon surrender of the temporary Notes at the office or agency of the Issuers in a Place of Payment, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Notes, the Issuers shall execute and the Trustee shall authenticate and deliver in exchange therefor one or more Definitive Notes, of any authorized denominations and of like tenor and aggregate principal amount. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits under this Indenture as Definitive Notes.

Section 1.08     Transfer and Exchange.

(a)                                 Transfer and Exchange of Global Notes. A Global Note may not be transferred except as a whole by the Depositary to a nominee of the Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. Global Notes will be exchanged by the Issuers for Definitive Notes if:

(1)                                 the Issuers deliver to the Trustee notice from the Depositary that it is unwilling or unable to continue to act as Depositary or that it is no longer a clearing agency registered under the Exchange Act and, in either case, a successor Depositary is

5

not appointed by the Issuers within 90 days after the date of such notice from the Depositary; or

(2)                                 there has occurred and is continuing a Default or Event of Default with respect to the Notes and the Depositary notifies the Trustee of its decision to exchange Global Notes for Definitive Notes.

Upon the occurrence of either of the preceding events in (1) or (2) above, Definitive Notes shall be issued in such names as the Depositary shall instruct the Trustee. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Section 1.07 and Section 1.09 hereof. Every Note authenticated and delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 1.08 or Section 1.07 or Section 1.09 hereof, shall be authenticated and delivered in the form of, and shall be, a Global Note. A Global Note may not be exchanged for another Note other than as provided in this Section 1.08(a), however, beneficial interests in a Global Note may be transferred and exchanged as provided in Section 1.08(b) or (f) hereof.

(b)                                 Transfer and Exchange of Beneficial Interests in the Global Notes. The transfer and exchange of beneficial interests in the Global Notes will be effected through the Depositary, in accordance with the provisions of this Indenture and the Applicable Procedures. Beneficial interests in the Restricted Global Notes will be subject to restrictions on transfer comparable to those set forth herein to the extent required by the Securities Act. Transfers of beneficial interests in the Global Notes also will require compliance with either subparagraph (1) or (2) below, as applicable, as well as one or more of the other following subparagraphs, as applicable:

(1)                                 Transfer of Beneficial Interests in the Same Global Note. Beneficial interests in any Restricted Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in the same Restricted Global Note in accordance with the transfer restrictions set forth in the Private Placement Legend; provided, however, that prior to the expiration of the Restricted Period, transfers of beneficial interests in the Regulation S Global Note may not be made to a U.S. Person or for the account or benefit of a U.S. Person (other than an initial purchaser). Beneficial interests in any Unrestricted Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in an Unrestricted Global Note. No written orders or instructions shall be required to be delivered to the Registrar to effect the transfers described in this Section 1.08(b)(1).

(2)                                 All Other Transfers and Exchanges of Beneficial Interests in Global Notes. In connection with all transfers and exchanges of beneficial interests that are not subject to Section 1.08(b)(1) above, the transferor of such beneficial interest must deliver to the Registrar either:

(A)                               both:

(i)                                     a written order from a Participant or an Indirect Participant given to the Depositary in accordance with the Applicable Procedures directing the Depositary to credit or cause to be credited a beneficial

6

interest in another Global Note in an amount equal to the beneficial interest to be transferred or exchanged; and

(ii)                                  instructions given in accordance with the Applicable Procedures containing information regarding the Participant account to be credited with such increase; or

(B)                               both:

(i)                                     a written order from a Participant or an Indirect Participant given to the Depositary in accordance with the Applicable Procedures directing the Depositary to cause to be issued a Definitive Note in an amount equal to the beneficial interest to be transferred or exchanged; and

(ii)                                  instructions given by the Depositary to the Registrar containing information regarding the Person in whose name such Definitive Note shall be registered to effect the transfer or exchange referred to in (1) above.

Upon consummation of an Exchange Offer by the Issuers in accordance with Section 1.08(f) hereof, the requirements of this Section 1.08(b)(2) shall be deemed to have been satisfied upon receipt by the Registrar of the instructions contained in the Letter of Transmittal delivered by the Holder of such beneficial interests in the Restricted Global Notes. Upon satisfaction of all of the requirements for transfer or exchange of beneficial interests in Global Notes contained in this Indenture and the Notes or otherwise applicable under the Securities Act, the Trustee shall adjust the principal amount of the relevant Global Note(s) pursuant to Section 1.08(h) hereof.

(3)                                 Transfer of Beneficial Interests to Another Restricted Global Note. A beneficial interest in any Restricted Global Note may be transferred to a Person who takes delivery thereof in the form of a beneficial interest in another Restricted Global Note if the transfer complies with the requirements of Section 1.08(b)(2) above and the Registrar receives the following:

(A)                               if the transferee will take delivery in the form of a beneficial interest in the 144A Global Note, then the transferor must deliver a certificate in the form of Exhibit B hereto, including the certifications in item (1) thereof; and

(B)                               if the transferee will take delivery in the form of a beneficial interest in the Regulation S Global Note, then the transferor must deliver a certificate in the form of Exhibit B hereto, including the certifications in item (2) thereof.

(4)                                 Transfer and Exchange of Beneficial Interests in a Restricted Global Note for Beneficial Interests in an Unrestricted Global Note. A beneficial interest in any Restricted Global Note may be exchanged by any holder thereof for a beneficial interest in an Unrestricted Global Note or transferred to a Person who takes delivery thereof in the form of a beneficial interest in an Unrestricted Global Note if the exchange or transfer complies with the requirements of Section 1.08(b)(2) above and:

7

(A)                               such exchange or transfer is effected pursuant to the Exchange Offer in accordance with the Registration Rights Agreement and the holder of the beneficial interest to be transferred, in the case of an exchange, or the transferee, in the case of a transfer, certifies in the applicable Letter of Transmittal that it is not (i) a Broker-Dealer, (ii) a Person participating in the distribution of the Exchange Notes or (iii) a Person who is an affiliate (as defined in Rule 144) of the Issuers;

(B)                               such transfer is effected pursuant to the Shelf Registration Statement in accordance with the Registration Rights Agreement;

Notwithstanding the foregoing, nothing herein shall prevent the Issuers, the Trustee or any agent of the Issuers or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or such nominee, as the case may be, that impair, as between the Depositary, members or participants of the Depositary and any other Person on whose behalf a member or participant of the Depositary may act, the operation of customary practices of such Persons governing the exercise of the rights of a beneficial holder of any Global Note.  Neither the Trustee nor any agent of the Trustee shall have any responsibility or liability for any actions taken or not taken by the Depositary.

(9)                                 Neither the Trustee nor any agent of the Trustee shall have any obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

(a) If (1) any mutilated Note is surrendered to the Trustee or (2) both (i) there shall be delivered to the Issuers and the Trustee (A) a claim by a Holder as to the destruction, loss or wrongful taking of any Note of such Holder and a request thereby for a new replacement Note, and (B) such indemnity bond as required by them to save each of them and any agent of either of them harmless and (ii) such other reasonable requirements as may be imposed by the Issuers as permitted by Section 8—405 of the Uniform Commercial Code have been satisfied, then, in the absence of notice to an Issuer or the Trustee that such Note has been acquired by a “protected purchaser” within the meaning of Section 8—405 of the Uniform Commercial Code, the Issuers shall execute and upon its request the Trustee shall authenticate and deliver, in lieu of any such mutilated, destroyed, lost or wrongfully taken Note, a new Note of like tenor and principal amount and bearing a number not contemporaneously Outstanding.

(b)                                 In case any such mutilated, destroyed, lost or wrongfully taken Note has become or is about to become due and payable, the Issuers in their discretion may, instead of issuing a new Note, pay such Note.

(c)                                  Upon the issuance of any new Note under this Section, the Issuers may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed

20

in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.

(d)                                 Every new Note issued pursuant to this Section in lieu of any destroyed, lost or wrongfully taken Note shall constitute an original additional contractual obligation of the Issuers, whether or not the destroyed, lost or wrongfully taken Note shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Notes duly issued hereunder.

(e)                                  The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or wrongfully taken Notes.

Section 1.10     Notice to Holders; Waiver. (a) Where this Indenture provides for notice to Holders of any event, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first—class postage prepaid, to each Holder affected by such event, at his address as it appears in the Register, not later than the latest date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such notice. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

(b)                                 In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder.

(c)                                  Notwithstanding anything to the contrary herein, where this Indenture provides for notice of any event to a Holder of a Global Note, such notice shall be sufficiently given if given to the Depositary for such Note (or its designee), pursuant to its Applicable Procedures, not later than the latest date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such notice.

Section 1.11     Cancellation. All Notes surrendered for payment, redemption, registration of transfer or exchange or conversion or for credit against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly canceled by it. The Issuers may at any time deliver to the Trustee for cancellation any Notes previously authenticated and delivered hereunder which the Issuers may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any Notes previously authenticated hereunder which the Issuers have not issued and sold, and all Notes so delivered shall be promptly canceled by the Trustee. No Notes shall be authenticated in lieu of or in exchange for any Notes canceled as provided in this Section, except as expressly permitted by this Indenture. All canceled Notes held by the

21

Trustee shall be disposed of in accordance with its customary procedures and the Trustee shall deliver copies of cancelled Notes to the Issuers pursuant to an Issuer Order; provided, however, that the Trustee shall not be required to destroy such canceled Notes.

Any such notice may be cancelled at any time prior to the mailing of notice of such redemption to any Holder and shall thereby be void and of no effect.

Section 3.02     Selection of Notes to Be Redeemed.

(a)                                 If less than all of the Notes are to be redeemed at any time, the Trustee shall select the Notes to be redeemed among the Holders as follows: (1) if the Notes are listed on any national securities exchange, in compliance with the requirements of the principal national securities exchange on which the Notes are listed; or (2) if the Notes are not listed on any national securities exchange, on a pro rata basis (except that any Notes represented by a Global Note will be selected by such method as DTC or its nominee or successor may require or, where such nominee or successor is the Trustee, a method that most nearly approximate pro rata selection unless otherwise required by law).

(b)                                 The Trustee shall promptly notify the Issuers in writing of the Notes selected for redemption and, in the case of any Note selected for partial redemption, the principal amount thereof to be redeemed. Notes and portions of Notes selected shall be in minimum amounts of at least $2,000 or integral multiples of $1,000 in excess of $2,000; except that if all of the Notes of a Holder are to be redeemed, the entire outstanding amount of Notes held by such Holder, even if not $2,000 or a multiple of $1,000, shall be redeemed. Provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption.

Section 3.03     Notice of Redemption.

(a)                                 At least 30 days but not more than 60 days before a redemption date, except that redemption notices may be sent more than 60 days prior to a redemption date if the notice is issued in connection with a Legal Defeasance, Covenant Defeasance or a satisfaction and discharge of this Indenture, the Issuers shall send a notice of redemption to each Holder whose Notes are to be redeemed at its registered address. Any redemption notice may, at the Company’s discretion, be subject to one or more conditions specified in the redemption notice, including completion of the related Equity Offering or the occurrence of the Change of Control, as applicable. The Issuers will provide the Trustee with notice of the satisfaction or waiver of such conditions, the delay of such redemption or the rescission of such notice of redemption in

58

the same manner that the related notice of redemption was given to the Trustee, and the Trustee will send a copy of such notice to the Holders in the same manner that the related notice of redemption was given to such Holders.

(b)                                 The notice shall identify the Notes to be redeemed and shall state:

(i)                                     the redemption date;

(ii)                                  the redemption price or, if the redemption price is not then determinable, the manner in which it is to be determined;

(iii)                               if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the redemption date upon surrender of such Note, a new Note or Notes in a principal amount equal to the unredeemed portion shall be issued in the name of the Holder upon cancellation of the original Note;

(iv)                              the name and address of the Paying Agent;

(v)                                 that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price;

(vi)                              that, unless the Issuers default in making such redemption payment, interest on Notes called for redemption shall cease to accrue on and after the redemption date and the only remaining right of the Holders of such Notes is to receive payment of the redemption price upon surrender to the Paying Agent of the Notes redeemed;

(vii)                           the paragraph of the Notes and/or Section of this Indenture pursuant to which the Notes called for redemption are being redeemed;

(viii)                        that no representation is made as to the correctness or accuracy of the CUSIP or ISIN number, if any, listed in such notice or printed on the Notes; and

(ix)                              any conditions precedent to the redemption and, if applicable, that, in the Company’s discretion, the date of redemption may be delayed until such time as any or all such conditions shall be satisfied or waived (provided that in no event shall such date of redemption be delayed to a date later than 60 days after the date on which such notice was sent), or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied or waived by the Issuers by the date of redemption, or by the date of redemption as so delayed.

(c)                                  If any of the Notes to be redeemed is in the form of a Global Note, then the Issuers shall modify such notice to the extent necessary to accord with the procedures of the Depository applicable to redemption.

(d)                                 A notice of redemption with respect to any redemption pursuant Section 3.07(c) need not set forth the Make-Whole Premium but only the manner of calculation thereof in reasonable detail. The Issuers will notify the Trustee of the Make-Whole Premium with respect

59

to any such redemption promptly after the calculation, and the Trustee shall not be responsible for such calculation.

(e)                                  At the Issuers’ request, the Trustee shall give the notice of optional redemption in the Issuers’ names and at their expense; provided, however, that the Issuers shall have delivered to the Trustee, as provided in Section 3.01, an Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in Section 3.03(b).

Section 3.04     Effect of Notice of Redemption.

Once notice of redemption is sent in accordance with Section 3.03 or Section 3.10 hereof, Notes called for redemption become irrevocably due and payable on the redemption date at the redemption price, subject to satisfaction of any conditions specified in the notice of redemption. If sent in the manner provided for in Section 3.03, the notice of redemption shall be conclusively presumed to have been given whether or not a Holder receives such notice. Failure to give timely notice or any defect in the notice shall not affect the validity of the redemption.

Section 3.05     Deposit of Redemption Price.

(a)                                 Prior to 11:00 a.m., New York City time, on the redemption date, the Issuers shall deposit with the Paying Agent (or, if the Company or a Subsidiary thereof is acting as its own Paying Agent, segregate and hold in trust as provided in Section 4.18 of this Indenture) money sufficient in same day funds to pay the redemption price of and accrued interest, if any, on all Notes to be redeemed on that date. The Paying Agent shall promptly return to the Issuers any money deposited with the Paying Agent by an Issuer in excess of the amounts necessary to pay the redemption price of and accrued interest, if any, on all Notes to be redeemed.

(b)                                 If the Issuers comply with the provisions of Section 3.05(a), on and after the redemption date, interest shall cease to accrue on the Notes or the portions of Notes called for redemption whether or not such Notes are presented for payment, and the only remaining right of the Holders of such Notes shall be to receive payment of the redemption price upon surrender to the Paying Agent of the Notes redeemed. If any Note called for redemption shall not be so paid upon surrender for redemption because of the failure of an Issuer to comply with Section 3.05(a), interest shall be paid on the unpaid principal, from the redemption date until such principal is paid, and to the extent lawful, on any interest not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01 hereof.

Section 3.06     Notes Redeemed in Part.

Upon surrender of a Note that is redeemed in part, the Issuers shall issue in the name of the Holder and the Trustee shall authenticate for the Holder at the expense of the Issuers a new Note equal in principal amount to the unredeemed portion of the Note surrendered; provided that each new Note shall be in a minimum principal amount of $2,000 or an integral multiple of $1,000 in excess thereof.

(4)                                 make any Restricted Investment

(all such payments and other actions set forth in these clauses (1) through (4) above being collectively referred to as “Restricted Payments”), unless, at the time of and after giving effect to such Restricted Payment, no Default (except a Reporting Default) or Event of Default has occurred and is continuing or would occur as a consequence of such Restricted Payment and either:

(a)           Available Cash from Operating Surplus with respect to the Company’s immediately preceding fiscal quarter, plus

(b)           100% of the aggregate net cash proceeds received by the Company, or the fair market value of any Permitted Business or long-term assets that are used or useful in a Permitted Business to the extent acquired in consideration of Equity Interests of the Company (other than Disqualified Stock), after the date of the completion of the Compression Acquisition as a contribution to its common equity capital or from the issue or sale of Equity Interests of the Company (other than Disqualified Stock) or from the

(e)           the aggregate amount of Incremental Funds previously expended pursuant to this clause (i) and clause (ii) below; or

(ii)           if the Fixed Charge Coverage Ratio for the Trailing Four Quarters is less than 1.75 to 1.0, such Restricted Payment, together with (without duplication of amounts included in clauses (a) or (b) below) the aggregate amount of all other Restricted Payments made by the Company and its Restricted Subsidiaries since the Issue Date (excluding Restricted Payments permitted by clauses (2), (3), (4), (5), (6), (7), (8), (9) and (10) of Section 4.07(b)) with respect to the quarter for which such Restricted Payment is made, is less than the sum, without duplication, of:

(3)           the purchase, redemption, defeasance or other acquisition or retirement of Indebtedness of the Company or any Guarantor that is subordinate in right of payment to the Notes or such Guarantor’s Subsidiary Guarantee thereof or Disqualified Stock of the Company or any Guarantor with the net cash proceeds from a substantially concurrent incurrence of, or in exchange for, Permitted Refinancing Indebtedness;

(6)           the purchase, redemption or other acquisition or retirement for value of Indebtedness of the Company or any Guarantor that is subordinated in right of payment to the Notes or a Subsidiary Guarantee at a purchase price not greater than (i) 101% of the principal

70

amount of such subordinated Indebtedness in the event of a Change of Control or (ii) 100% of the principal amount of such subordinated Indebtedness in the event of an Asset Sale, in each case, plus accrued and unpaid interest thereon, in connection with any offer to purchase similar to a Change of Control Offer or Asset Sale Offer required by the terms of such Indebtedness, but only if:

(a)           in the case of a Change of Control, the Company has first complied with and fully satisfied its obligations under Section 4.15; or

(b)           in the case of an Asset Sale, the Company has first complied with and fully satisfied its obligations in accordance with Section 4.10;

(c)                                  The amount of all Restricted Payments (other than cash) will be the fair market value on the date of the Restricted Payment or the Restricted Investment proposed to be made or the asset(s) or securities proposed to be transferred or issued by the Company or such Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment, except that the fair market value of any non-cash dividend or distribution made within 60 days after the date of declaration shall be determined as of such date of declaration. The fair market value of any Restricted Investment, assets or securities that are required to be valued by this Section 4.07 shall be determined, in the case of amounts under $50.0 million, by an officer of the General Partner and, in the case of amounts over $50.0 million, by the Board of Directors of the Company, whose determination shall be evidenced by a Board Resolution. For purposes of determining compliance with this Section 4.07, (x) in the event that a Restricted Payment meets the criteria of more than one of the exceptions described in clauses (1) through (10) of Section 4.07(b), the Company shall be permitted, in its sole discretion, to classify such Restricted Payment, or later

71

classify, reclassify or re-divide all or a portion of such Restricted Payment, in any manner that complies with this Section 4.07; and (y) in the event a Restricted Payment is made pursuant to clause (i) or (ii) of Section 4.07(a), the Company will be permitted to classify whether all or any portion thereof is being made with Incremental Funds.

Section 4.08          Limitation on Dividend and Other Payment Restrictions Affecting Subsidiaries.

(a)                                 The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or permit to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary to:

(i)            pay dividends or make any other distributions on its Capital Stock to the Company or any of its Restricted Subsidiaries, or pay any Indebtedness or other obligations owed to the Company or any of its Restricted Subsidiaries; provided that preferences on payments of dividends or distributions in preferred securities will not be deemed to constitute a restriction under the foregoing so long as the terms of such preferred securities do not expressly restrict the ability of such Restricted Subsidiary to pay dividends or make distributions on its Capital Stock;

(ii)           make loans or advances to the Company or any of its Restricted Subsidiaries; or

(iii)          transfer any of its properties or assets to the Company or any of its Restricted Subsidiaries.

(b)                                 However, Section 4.08(a) will not apply to encumbrances or restrictions existing under or by reason of:

(i)            agreements (including the Credit Agreement) as in effect on the Issue Date and any amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings of those agreements or the Indebtedness to which they relate, provided that the amendments, modifications, restatements, renewals, increases, supplements, refundings, replacements or refinancings are not materially more restrictive, taken as a whole, with respect to such dividend, distribution and other payment and transfer restrictions than those contained in those agreements on the Issue Date;

(ii)           this Indenture, the Notes and the Subsidiary Guarantees;

(iii)          Applicable Law;

(iv)          any instrument of a Person acquired by the Company or any of its Restricted Subsidiaries as in effect at the time of such acquisition, which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired, provided that, in the case of any instrument governing Indebtedness, such Indebtedness was otherwise permitted by the terms of this Indenture to be incurred;

72

(v)           Capital Lease Obligations, mortgage financings or purchase money obligations, in each case for property acquired in the ordinary course of business that impose restrictions on that property of the nature described in clause (iii) of Section 4.08(a);

(vi)          any agreement for the sale or other disposition of all or substantially all the Capital Stock or assets of a Restricted Subsidiary of the Company that restricts distributions by that Restricted Subsidiary pending its sale or other disposition or other customary restrictions pursuant thereto;

(vii)         Permitted Refinancing Indebtedness, provided that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being Refinanced, as determined in good faith by the Company;

(viii)        Liens securing Indebtedness otherwise permitted to be incurred under the provisions of Section 4.12 that limit the right of the debtor to dispose of the assets subject to such Liens;

(ix)          customary provisions limiting the disposition or distribution of assets or property in joint venture agreements, asset sale agreements, stock sale agreements and other similar agreements or other customary restrictions pursuant thereto;

(xi)          restrictions on cash, Cash Equivalents or other deposits or net worth imposed by customers under contracts entered into in the ordinary course of business;

(xii)         any other agreement governing Indebtedness or Disqualified Stock or preferred securities of the Company or any Guarantor that is permitted to be incurred or issued by Section 4.09; provided, however, that such encumbrances or restrictions either (a) are not materially more restrictive, taken as a whole, than those contained in this Indenture or the Credit Agreement as in effect on the Issue Date, or (b) in the good faith judgment of a responsible officer of the Company, would not reasonably be expected to have a material adverse effect on the Company’s ability to make required payments on the Notes; and

(xiii)        Hedging Contracts permitted from time to time under this Indenture.

Section 4.09          Limitation on Incurrence of Indebtedness and Issuance of Preferred Securities.  (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness (including Acquired Debt); the Company will not, and will not permit any of its Restricted Subsidiaries to, issue any Disqualified Stock; and the Company will not permit any of its Restricted Subsidiaries to issue any preferred securities; provided, however, that the Issuers and any of the Guarantors may incur Indebtedness (including Acquired Debt) or issue Disqualified Stock or preferred securities, if, for the Company’s most recently ended four full

73

fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock or preferred securities are issued, the Fixed Charge Coverage Ratio would have been at least 2.0 to 1.0, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or Disqualified Stock or preferred securities had been issued, as the case may be, at the beginning of such four-quarter period.

(b)                                 Section 4.09(a) will not prohibit the incurrence or issuance of any of the following items of Indebtedness or Disqualified Stock or preferred securities (collectively, “Permitted Debt”) described below:

(1)           the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness (including letters of credit) under one or more Credit Facilities, provided that, after giving effect to any such incurrence, the aggregate principal amount of all Indebtedness incurred under this clause (1) (with letters of credit being deemed to have a principal amount equal to the maximum potential liability of the Company and its Subsidiaries thereunder) and then outstanding does not exceed the greater of (a) $1.6 billion and (b) the sum of $820.0 million and 30.0% of the Company’s Consolidated Net Tangible Assets as of the date of incurrence;

(2)           the incurrence by the Company or its Restricted Subsidiaries of the Existing Indebtedness;

(3)           the incurrence by the Issuers and the Guarantors of Indebtedness represented by the Notes and the related Subsidiary Guarantees issued on the Issue Date and the Exchange Notes and related guarantees to be issued in exchange for the Notes and the Subsidiary Guarantees pursuant to the Registration Rights Agreement (other than any Additional Notes);

(4)           the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case, incurred for the purpose of financing all or any part of the purchase price or cost of construction or improvement of property, plant or equipment used in the business of the Company or such Restricted Subsidiary, including all Permitted Refinancing Indebtedness incurred to extend, refinance, renew, replace, defease or refund any Indebtedness incurred pursuant to this clause (4), provided that after giving effect to any such incurrence, the principal amount of all Indebtedness incurred pursuant to this clause (4) and then outstanding does not exceed the greater of (a) $40.0 million and (b) 2.0% of the Company’s Consolidated Net Tangible Assets as of the date of incurrence;

(5)           the incurrence or issuance by the Company or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to, extend, refinance, renew, replace, defease or refund, Indebtedness (other than intercompany Indebtedness) or Disqualified Stock of the Company or any Restricted Subsidiary that was permitted by this Indenture to be incurred under Section 4.09(a) or clauses (2), (3) or (11) of this Section 4.09(b) or this clause (5);

74

(6)           the incurrence by the Company or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries; provided, however, that:

(a)           if the Company is the obligor on such Indebtedness and a Guarantor is not the obligee, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations with respect to the Notes, or if a Guarantor is the obligor on such Indebtedness and neither the Company nor another Guarantor is the obligee, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all Obligations with respect to the Subsidiary Guarantee of such Guarantor; and

(b)           (i)  any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary of the Company and (ii) any sale or other transfer of any such Indebtedness to a Person that is neither the Company nor a Restricted Subsidiary of the Company will be deemed, in each case, to constitute an incurrence (as of the date of such issuance or transfer) of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (6);

(7)           the incurrence by the Company or any of its Restricted Subsidiaries of obligations under Hedging Contracts in the ordinary course of business and not for speculative purposes;

(8)           the guarantee by the Company or any of its Restricted Subsidiaries of Indebtedness of the Company or any of its Restricted Subsidiaries that was permitted to be incurred by another provision of this Section 4.09; provided that in the event such Indebtedness being guaranteed is subordinated in right of payment to the Notes or the Subsidiary Guarantees, then the guarantee shall be subordinated in right of payment to the Notes or the Subsidiary Guarantees, as the case may be;

(9)           the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness in respect of self-insurance, bid, performance, surety and similar bonds issued for the account of the Company and any of its Restricted Subsidiaries in the ordinary course of business, including guarantees and obligations of the Company or any of its Restricted Subsidiaries with respect to letters of credit supporting such obligations (in each case other than an obligation for money borrowed);

(10)         the issuance by any of the Company’s Restricted Subsidiaries to the Company or to any of its Restricted Subsidiaries of any Disqualified Stock or preferred securities; provided, however, that:

(a)           any subsequent issuance or transfer of Equity Interests that results in any such Disqualified Stock or preferred securities being held by a Person other than the Company or a Restricted Subsidiary of the Company; and

(b)           any sale or other transfer of any such Disqualified Stock or preferred securities to a Person that is not either the Company or a Restricted Subsidiary of the Company,

75

shall be deemed, in each case, to constitute an issuance of such Disqualified Stock or preferred securities by such Restricted Subsidiary that was not permitted by this clause (10);

(11)         the incurrence by the Company or any of its Restricted Subsidiaries of Acquired Debt in connection with a merger or consolidation satisfying either one of the financial tests set forth in Section 5.01(a)(iv);

(12)         the incurrence of Indebtedness of the Company or any of its Restricted Subsidiaries arising from the honoring by a bank or other financial institution of a check, draft or similar instrument inadvertently (except in the case of daylight overdrafts) drawn against insufficient funds in the ordinary course of business; provided, however, that such Indebtedness is extinguished within five Business Days of incurrence;

(13)         the incurrence of Indebtedness or the issuance of Disqualified Stock or preferred securities of any of the Company and the Restricted Subsidiaries to the extent the net proceeds thereof are concurrently (a) used to redeem all of the outstanding Notes or (b) deposited to effect Covenant Defeasance or Legal Defeasance or satisfy and discharge this Indenture as described in Article Seven and Article Ten;

(14)         the incurrence of Indebtedness of the Company or any of its Restricted Subsidiaries consisting of the financing of insurance premiums in customary amounts consistent with the operations and business of the Company and the Restricted Subsidiaries; and

(15)         the incurrence by the Company or any of its Restricted Subsidiaries of additional Indebtedness or the issuance by the Company or any of its Restricted Subsidiaries of Disqualified Stock; provided that, after giving effect to any such incurrence or issuance, the aggregate principal amount of all Indebtedness incurred and Disqualified Stock issued under this clause (15) and then outstanding does not exceed the greater of (a) $75.0 million and (b) 4.0% of the Company’s Consolidated Net Tangible Assets as of the date of incurrence or issuance.

(c)                                  For purposes of determining compliance with this Section 4.09, in the event that an item of Indebtedness or Disqualified Stock or preferred securities (including Acquired Debt) meets the criteria of more than one of the categories of Permitted Debt described in clauses (1) through (15) above, or is entitled to be incurred pursuant to Section 4.09(a), the Company will be permitted to classify (or later classify or reclassify in whole or in part in its sole discretion) such item of Indebtedness or Disqualified Stock or preferred securities in any manner (including by dividing and classifying such item of Indebtedness or Disqualified Stock or preferred securities in more than one type of Indebtedness or Disqualified Stock or preferred securities permitted under such covenant) that complies with this Section 4.09; provided that any Indebtedness under the Credit Facilities on the Issue Date and on the date of the completion of the Compression Acquisition shall be considered incurred under clause (1) of the definition of “Permitted Debt” and may not later be reclassified. The dollar equivalent principal amount of any Indebtedness denominated in a foreign currency and incurred pursuant to any dollar- denominated restriction on the incurrence of Indebtedness shall be calculated based on the relevant exchange rates in effect at the time of incurrence, in the case of term Indebtedness, or first committed, in the case of revolving credit Indebtedness.

76

(d)                                 The accrual of interest, the accretion or amortization of original issue discount, the accretion of principal with respect to a non-interest bearing or other discount security, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, and the payment of dividends on Disqualified Stock or preferred securities in the form of additional shares of the same class of Disqualified Stock or preferred securities will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock or preferred securities for purposes of this Section 4.09. For purposes of this Section 4.09, (i) the accrual of an obligation to pay a premium in respect of Indebtedness or Disqualified Stock or preferred securities arising in connection with the issuance of a notice of redemption or making of a mandatory offer to purchase such Indebtedness or Disqualified Stock or preferred securities and (ii) unrealized losses or charges in respect of Hedging Contracts (including those resulting from the application of ASC-815) will, in case of clause (i) or (ii), not be deemed to be an incurrence of Indebtedness or issuance of Disqualified Stock or preferred securities. Further, the accounting reclassification of any obligation or Disqualified Stock or preferred securities of the Company or any of its Restricted Subsidiaries as Indebtedness or Disqualified Stock or preferred securities will not be deemed an incurrence of Indebtedness or issuance of Disqualified Stock or preferred securities for purposes of this Section 4.09; provided that, for the avoidance of doubt, if the Company permits any amendment, waiver or other action with respect to the Preferred Units such that the Preferred Units would constitute “Indebtedness” or “Disqualified Stock” under this Indenture, then such amendment, waiver or other action with respect to the Preferred Units will be deemed an incurrence of Indebtedness or issuance of Disqualified Stock, as applicable, for purposes of this covenant.

(e)                                  For purposes of determining any particular amount of Indebtedness under this Section 4.09, (i) guarantees of, or obligations in respect of letters of credit relating to, Indebtedness otherwise included in the determination of such amount shall not also be included and (ii) if obligations in respect of letters of credit are incurred pursuant to a Credit Facility and are being treated as incurred pursuant to clause (1) of the definition of “Permitted Debt” and the letters of credit relate to other Indebtedness, then such other Indebtedness shall not be included.

Section 4.10          Limitation on Asset Sales.

(a)                                 The Company will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless:

(i)            the Company (or a Restricted Subsidiary, as the case may be) receives consideration at the time of the Asset Sale at least equal to the fair market value, determined as of the date of the agreement with respect thereto, of the assets or Equity Interests issued or sold or otherwise disposed of; and

(ii)           at least 75% of the aggregate consideration received by the Company and its Restricted Subsidiaries in the Asset Sale and all other Asset Sales since the Issue Date, on a cumulative basis, is in the form of cash or Cash Equivalents. For purposes of this provision, each of the following will be deemed to be cash:

(1)                                 any liabilities, as shown on the Company’s most recent consolidated balance sheet, of the Company or such Restricted Subsidiary that are assumed by the transferee of any

77

such assets pursuant to an agreement that releases the Company or such Restricted Subsidiary from or indemnifies the Company or such Restricted Subsidiary against further liability;

(2)                                 any securities, notes or other obligations received by the Company or any Restricted Subsidiary from such transferee that are, within 180 days after the Asset Sale, converted by the Company or such Restricted Subsidiary into cash, to the extent of the cash received in that conversion;

(3)                                 any stock or assets of the kind referred to in clause (ii), (iii) or (v) of Section 4.10(b); and

(4)                                 any Designated Non-cash Consideration received by the Company or such Restricted Subsidiary in such Asset Sale having an aggregate fair market value, taken together with all other Designated Non-cash Consideration received since the Issue Date pursuant to this clause (4) that at the time has not been converted to cash, not to exceed the greater of (x) $75.0 million and (y) 3.5% of Consolidated Net Tangible Assets at the time of the receipt of such Designated Non-cash Consideration, with the fair market value of each item of Designated Non-cash Consideration being measured at the time received and without giving effect to subsequent changes in value.

(b)                                 Within 365 days after the receipt of any Net Proceeds from an Asset Sale, the Company or any Restricted Subsidiary may apply those Net Proceeds at its option to any combination of the following:

(i)            to repay, repurchase or redeem Senior Debt (and in the case of repaying Senior Debt under any revolving credit agreement, including the Credit Agreement, to permanently reduce commitments thereunder by a corresponding amount);

(ii)           to acquire all or substantially all of the properties or assets of a Person primarily engaged in a Permitted Business;

(iii)          to acquire Voting Stock of a Person primarily engaged in a Permitted Business, if such Person is, or after giving effect to any such acquisition, such Person becomes, a Restricted Subsidiary;

(iv)          to make capital expenditures in respect of a Permitted Business; or

(v)           to acquire other long-term assets that are used or useful in a Permitted Business.

(c)                                  The acquisition of stock or assets, or making of a capital expenditure, pursuant to clauses (ii), (iii), (iv) or (v) of Section 4.10(b) shall be deemed to be satisfied if an agreement committing to make the acquisitions or expenditure referred to therein is entered into by the Company or any Restricted Subsidiary within the time period specified in Section 4.10(b) and such Net Proceeds are subsequently applied in accordance with such agreement within six months following the date such agreement is entered into.

78

(d)                                 Pending the final application of any Net Proceeds, the Company or any Restricted Subsidiary may invest the Net Proceeds in any manner that is not prohibited by this Indenture. Any Net Proceeds from Asset Sales that are not applied or invested as provided in Section 4.10(b) will constitute “Excess Proceeds.”

(e)                                  On the 366th day after the Asset Sale (or, at the Company’s option, any earlier date), if the aggregate amount of Excess Proceeds then exceeds $25.0 million, the Company will make an Asset Sale Offer to all Holders (with a copy to the Trustee), and to all holders of other Pari Passu Indebtedness containing provisions similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets, to purchase the maximum principal amount of Notes and such other Pari Passu Indebtedness that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal to 100% of the principal amount plus accrued and unpaid interest, if any, to the Settlement Date, subject to the right of Holders of record on the relevant record date to receive interest due on an Interest Payment Date that is on or prior to the Settlement Date, and will be payable in cash. The Company may satisfy the foregoing obligations with respect to any Net Proceeds from an Asset Sale by making an Asset Sale Offer with respect to such Net Proceeds prior to the expiration of the relevant 365 days (or such longer period provided above). If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company or any Restricted Subsidiary may use those Excess Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Notes and other Pari Passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Company will select the Notes and such Pari Passu Indebtedness to be purchased on a pro rata basis as set forth in Section 3.09(c)(8). Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

(f)                                   The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.10, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.10 by virtue of such conflict.

(g)                                  The provisions under this Indenture relating to the Company’s obligation to make an offer to repurchase the Notes as a result of an Asset Sale may be waived or modified with the written consent of the Holders of a majority in principal amount of the outstanding Notes.

Section 4.11  Limitation on Transactions with Affiliates.

(a)                                 The Company will not, and will not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of the Company, in each case, other than any such transaction or series of transactions that does not involve consideration in excess of $5.0 million (each, an “Affiliate Transaction”), unless:

79

(i)            the Affiliate Transaction is on terms, taken as a whole, that are no less favorable to the Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person or, if in the good faith judgment of the Board of Directors of the Company, no comparable transaction is available with which to compare such Affiliate Transaction, such Affiliate Transaction is otherwise fair to the Company or the relevant Restricted Subsidiary from a financial point of view and when such transaction is taken in its entirety; and

(ii)           the Company delivers to the Trustee, with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of $35.0 million, an Officers’ Certificate certifying that such Affiliate Transaction complies with this Section 4.11 and that such Affiliate Transaction has been approved by a majority of the disinterested members of the Board of Directors of the Company or the Company’s Conflicts Committee (or other committee serving a similar function).

(b)                                 The following items will not be deemed to be Affiliate Transactions and, therefore, will not be subject to the provisions of Section 4.11(a):

(i)            any employment, severance, employee benefit, director or officer indemnification, equity award, equity option or equity appreciation or other compensation agreement or plan entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business and payments, awards, grants or issuances of securities pursuant thereto (including any of the foregoing for the benefit of employees, officer and directors of Affiliates of the Company);

(ii)           transactions between or among any of the Company and its Restricted Subsidiaries;

(iii)          transactions with a Person (other than an Unrestricted Subsidiary of the Company) that is an Affiliate of the Company solely because the Company owns, directly or through a Restricted Subsidiary, an Equity Interest in, or otherwise controls, such Person;

(iv)          transactions effected in accordance with (a) the terms of agreements or arrangements in effect on the Issue Date, including the Services Agreement, the Partnership Agreement in the form attached as Exhibit B to the Contribution Agreement and the other agreements governing the Transactions, (b) any amendment or replacement of any of such agreements or (c) any agreements entered into hereafter that are similar to any of such agreements, so long as, in the case of clause (b) or (c), the terms of any such amendment or replacement agreement or future agreement are, on the whole, either not materially less advantageous to the Company or not materially less favorable to the Holders than the agreement so amended or replaced or the similar agreement referred to in the preceding clause (a), respectively;

(v)           customary compensation, indemnification and other benefits made available to officers, directors or employees of the Company or a Restricted Subsidiary or Affiliate of the Company, including reimbursement or advancement of out-of-pocket expenses and provisions of officers’ and directors’ liability insurance;

80

(vi)          sales of Equity Interests (other than Disqualified Stock) to Affiliates of the Company, or receipt by the Company of capital contributions from holders of its Equity Interests, or payments to Affiliates with respect to Indebtedness of the Company or any Restricted Subsidiary in accordance with its terms, provided that the Affiliate is treated no more favorably than other holders of such Indebtedness;

(vii)         Permitted Investments or Restricted Payments that are permitted by Section 4.07;

(viii)        payments to the General Partner with respect to reimbursement for expenses in accordance with the Partnership Agreement in the form attached as Exhibit B to the Contribution Agreement and as it may be amended, modified or supplemented from time to time, so long as any such amendment, modification or supplement is no less favorable to the Company in any material respect than the agreement prior to such amendment, modification or supplement;

(ix)          (a) guarantees by the Company or any of its Restricted Subsidiaries of performance of obligations of Unrestricted Subsidiaries or Joint Ventures in the ordinary course of business, except for guarantees of Indebtedness in respect of borrowed money, and (b) pledges by the Company or any Restricted Subsidiary of Capital Stock in Unrestricted Subsidiaries or Joint Ventures for the benefit of lenders or other creditors of Unrestricted Subsidiaries or Joint Ventures as contemplated by clause (9) of the definition of “Permitted Liens” so long as any such transaction described in this clause (b), if involving aggregate consideration in excess of $50.0 million, has been approved by a majority of the disinterested members of the Board of Directors of the Company or the Conflicts Committee of the Company;

(x)           transactions between the Company and any Person, a director of which is also a director of the General Partner or, if applicable, the Company, and such common director is the sole cause for such other Person to be deemed an Affiliate of the Company or any of its Restricted Subsidiaries; provided, however, that such director abstains from voting as a director of the General Partner or, if applicable, the Company on any matter involving such other Person;

(xi)          any transaction in which the Company or any of its Restricted Subsidiaries, as the case may be, delivers to the Trustee a letter from an Independent Advisor stating that such transaction is fair to the Company or such Restricted Subsidiary from a financial point of view or that such transaction meets the requirements of clause (i) of Section 4.11(a); and

(xii)         in the case of contracts for supplies, raw materials, inventory or other goods or services or activities reasonably related or ancillary thereto, or other operational contracts, any such contracts are entered into in the ordinary course of business on terms substantially similar to those contained in similar contracts entered into by the Company or any Restricted Subsidiary and unrelated third parties, or if neither the Company nor any Restricted Subsidiary has entered into a similar contract with a third party, then the terms are no less favorable than those that would reasonably be expected to be available from third parties on an arm’s-length basis.

81

Section 4.12          Limitation on Liens.

The Company will not and will not permit any of its Restricted Subsidiaries to, create, incur, assume or otherwise cause or suffer to exist or become effective any Lien of any kind (other than Permitted Liens) securing Indebtedness upon any of their property or assets, now owned or hereafter acquired, unless the Notes or any Subsidiary Guarantee of such Restricted Subsidiary, as applicable, is secured on an equal and ratable basis with (or on a senior basis (to at least the same extent as the Notes or such Subsidiary Guarantee are senior in right of payment) to, in the case of obligations subordinated in right of payment to the Notes or such Subsidiary Guarantee, as the case may be) the obligations so secured until such time as such obligations are no longer secured by a Lien. Any Lien created for the benefit of the Holders pursuant to the preceding sentence shall provide by its terms that such Lien shall be automatically and unconditionally released and discharged upon the release and discharge of the initial Lien.

Section 4.13          Additional Subsidiary Guarantees.

If, after the Issue Date, any Restricted Subsidiary of the Company that is not already a Guarantor (x) borrows, or guarantees any Indebtedness of either of the Issuers or any other Guarantors, under the Credit Agreement or (y) guarantees any Indebtedness of either of the Issuers or any other Guarantor under any other Credit Facility in excess of the De Minimis Amount, then that Subsidiary will become a Guarantor by executing a supplemental indenture substantially in the form of Exhibit D hereto and delivering it to the Trustee within 20 Business Days of the date on which it guaranteed or incurred such Indebtedness, as the case may be, together with any Officers’ Certificate or Opinion of Counsel required by Section 8.06; provided, however, that the preceding shall not apply to Subsidiaries of the Company that have properly been designated as Unrestricted Subsidiaries in accordance with this Indenture for so long as they continue to constitute Unrestricted Subsidiaries. Notwithstanding the preceding, any Subsidiary Guarantee of a Restricted Subsidiary that was incurred pursuant to this Section 4.13 will be subject to the limitations and provisions, including the release provisions, described under Article Nine.

Section 4.14          Existence.

Except as otherwise permitted pursuant to the terms hereof (including consolidation and merger permitted by Section 5.01 or Section 9.04), the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect its partnership existence, and the corporate, partnership, limited liability company or other existence of each of its Restricted Subsidiaries, in accordance with the respective organizational documents (as the same may be amended from time to time) of the Company or any such Restricted Subsidiary; provided, however, that the Company shall not be required to preserve the existence of any of its Restricted Subsidiaries (except Finance Corp.) if the Company in good faith shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Restricted Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders.

82

Section 4.15          Offer to Repurchase Upon Change of Control.

(a)           If a Change of Control occurs, unless the Issuers have previously or concurrently exercised their right to redeem all of the Notes pursuant to Section 3.07, the Company shall make an offer (a “Change of Control Offer”) to repurchase all or any part (in minimum denominations of $2,000 or an integral multiple of $1,000 in excess of $2,000) of each Holder’s Notes at a purchase price (the “Change of Control Payment”) in cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest thereon to the date of settlement (the “Change of Control Settlement Date”), subject to the right of Holders of record on the relevant record date to receive interest due on an Interest Payment Date that is on or prior to the Change of Control Settlement Date. Within 30 days following a Change of Control, unless the Issuers have previously or concurrently exercised their right to redeem all of the Notes pursuant to Section 3.07, the Company shall send a notice of the Change of Control Offer to each Holder and the Trustee describing the transaction or transactions that constitute the Change of Control and stating:

(i)            that the Change of Control Offer is being made pursuant to this Section 4.15 and that all Notes validly tendered and not validly withdrawn will be accepted for payment;

(ii)           the purchase price and the expiration date of the offer and the Change of Control Settlement Date, which shall be no earlier than 30 days but no later than 60 days from the date such notice is sent; provided that the Change of Control Settlement Date may be delayed, in the Company’s discretion, until such time (provided that in no event shall such Change of Control Settlement Date be delayed to a date later than 60 days from the date such notice is sent) as any or all such conditions referred to in clause (ix) below shall be satisfied or waived;

(iii)          that the Change of Control Offer will expire as of the time specified in such notice and that the Company shall pay the Change of Control Payment for all Notes accepted for purchase as of the expiration date promptly thereafter on the Change of Control Settlement Date (which shall be no later than five Business Days after the date such Change of Control Offer expires);
