RECITALS

WHEREAS, the Issuer is the owner of the Owner Compressors;

WHEREAS, the Manager is in the business of providing contract compression services relating to the use of Compressors to various Users thereof; and

WHEREAS, the Issuer and the Manager desire to enter into this Agreement pursuant to which the Manager will operate, maintain, manage and provide contract compression services for the Owner Compressors to Users on behalf of the Issuer.

NOW, THEREFORE, in consideration of the premises and mutual representations, warranties, covenants and agreements contained herein, the parties hereto hereby agree as follows:

1.             DEFINITIONS

Capitalized terms used in this Agreement and not otherwise defined herein shall have the meanings assigned to such terms in Appendix A to the Indenture, dated as of October 28, 2005 (as amended, modified or supplemented from time to time in accordance with its terms, the “Indenture”), between the Issuer and ▇▇▇▇▇ Fargo Bank, National Association, as indenture trustee (together with its successors and assigns, the “Indenture Trustee”), as such Appendix A may be amended, supplemented or otherwise modified from time to time in accordance with the provisions of the Indenture, and the rules of usage set forth in such Appendix A shall apply to this Agreement.

2.             APPOINTMENT OF THE MANAGER

2.1           Appointment.  Upon the terms and conditions hereinafter provided, the Issuer hereby appoints UCI as the initial Manager of the Owner Compressors.  The Manager shall be responsible for providing contract compression services, maintaining, operating and managing the Owner Compressors on behalf of the Issuer. UCI, as initial Manager, and each other Replacement Manager as may from time to time become Manager hereunder, hereby accepts such appointment and agrees to so maintain, operate and manage the Owner Compressors, and provide contract compression services therefor, in accordance with this Agreement.

2.2           Standard of Performance.  In performing its obligations hereunder (including UCI’s obligations (x) to identify Collections that are allocable to the Securitization Collateral and (y) to perform its obligations under the Intercreditor Agreement), the Manager shall use such efforts which are in

1

accordance with the Services Standard.  The duties of the Manager will be limited to those expressly set forth in this Agreement and the Related Documents and the Manager will not have any fiduciary or other implied duties or obligations to the Issuer or any of its assignees.

2.3           Conflicts of Interest.  The Manager shall perform its duties and obligations under this Agreement on a fair and equitable basis.  Without prejudice to the generality of the foregoing, the Manager will not discriminate between the Owner Compressors and any Other UCI Compressor (or, in the case of any Manager other than UCI or a Universal Affiliate, Compressors or any other equipment of a type similar to the Owner Compressors that is owned, managed or for which contract compression services are provided by such Manager for its own account) on any basis which could reasonably be considered discriminatory or adverse.

2.4           Similar Services.  It is expressly understood and agreed that nothing herein shall be construed to prevent, prohibit or restrict the Manager or any Affiliate of the Manager from providing the same or similar services as those provided under this Agreement to any other Person or from manufacturing, selling, owning, providing contract compression services, managing, maintaining, operating or otherwise dealing with Compressors on its or others’ behalf; provided that no such activity shall in any way reduce the obligations of the Manager hereunder to comply with the Services Standard.

2.5           Use of Affiliates.  The Issuer hereby consents to and agrees that, in performing its duties hereunder, the Manager may further contract with its Affiliates to provide any or all services to be provided by the Manager pursuant to this Agreement; provided that the Manager shall remain liable for all services to be provided by the Manager which its Affiliates have contracted to perform; provided, further, that the Manager shall pay the fees and expenses (which shall be negotiated and determined at an arms-length basis) of all such Affiliates with which the Manager shall have so contracted.

2.6           Relationship between the Issuer and the Manager.  All of the functions, duties and services performed by the Manager under this Agreement shall be performed by the Manager as an independent contractor and not as an agent of the Issuer except to the limited extent set forth in the following sentence.  The Manager does not have the authority to act as an agent of the Issuer and the Manager, in its capacity as such, does not, except as to the execution of User Contracts with respect to the Owner Compressors, have the authority to bind the Issuer or its assets.  The Issuer shall not have any liability for the acts of the Manager.  Any fee or other compensation payable by the Issuer to the Manager is an ordinary and necessary business expense of the Issuer.

2.7           Back-up Manager.  If the Back-up Manager or any other Person shall become the Replacement Manager, then the Requisite Global Majority shall have the right to appoint another Eligible Back-up Manager as Back-up Manager.

3.             MANAGEMENT TERM

3.1           Duration of Management Term.  The Management Term shall commence as of the Closing Date and shall continue in force with respect to an Owner Compressor until the earliest to occur of:  (i) the occurrence of a Compressor Termination Event with respect to such Owner Compressor, (ii) the date on which the Indenture is discharged in accordance with its terms and all Outstanding Obligations (including all amounts owing to any Series Enhancer pursuant to any Enhancement Agreement) have been paid in full, and (iii) with respect to any Manager, the removal and replacement of the Manager in accordance with the provisions of Section 12 hereof.  Except as set forth in this Section 3 or Section 12 hereof, the rights and obligations of the Manager hereunder may not be terminated by, or on behalf of, the Issuer for any reason.

2

3.2           Resignation by Manager.  Neither UCI nor any successor Manager may resign from its obligations and duties as the Manager hereunder, except (i) with the prior written consent of the Requisite Global Majority or (ii) upon a determination that the performance by UCI or any successor Manager, as the case may be, of its duties under this Agreement is no longer permissible under Applicable Law, which determination shall be evidenced by an Opinion of Counsel, in form and substance reasonably satisfactory to the Requisite Global Majority, to such effect addressed and delivered to the Indenture Trustee (on behalf of the Noteholders, each Series Enhancer and the other Persons specified in the Indenture), the Issuer and each Series Enhancer.  No such resignation will become effective until a Replacement Manager has assumed the obligations and duties of the Manager under this Agreement in accordance with the terms hereof.

3.3           Termination with Respect to an Owner Compressor.  Notwithstanding the other provisions of this Section 3 to the contrary (but subject to the provisions of Section 12), the Management Term shall terminate with respect to any Owner Compressor which is subject to a Casualty Loss, sold, foreclosed upon, lost, stolen, damaged beyond repair, requisitioned (other than a temporary requisition for a period of not more than 180 days) by any Governmental Authority, worn out, unsuitable for use or economically obsolete (any of the foregoing, a “Compressor Termination Event”) as of the date of such Compressor Termination Event after the deposit into the Trust Account of all Casualty Proceeds and other amounts received with respect to such Owner Compressor.  The Issuer and the Manager shall notify the other party and the Indenture Trustee promptly after it obtains knowledge of any Compressor Termination Event.

4.             OWNERSHIP OF OWNER COMPRESSORS

4.1           Retention of Title.  The Issuer  shall at all times retain full legal and equitable title to its Owner Compressors, notwithstanding the management thereof by the Manager hereunder. The Manager shall not make reference to or otherwise deal with or treat the Owner Compressors in any manner except in conformity with this Section 4.1.

4.2           Liens.  The Manager will promptly pay or discharge any and all sums claimed by any party which, if unpaid, might become a Lien, charge, security interest or other encumbrance upon or with respect to any Owner Compressor, including any accession thereto, or any part thereof or the interest of the Issuer therein other than Permitted Encumbrances (each a “Lien Claim”) and will promptly discharge any Lien Claim which arises; provided, however, that the Manager shall be under no obligation to pay or discharge any Lien Claim so long as it is contesting the validity thereof in good faith, in a reasonable manner and by appropriate legal proceedings, and the nonpayment thereof does not, in the commercially reasonable opinion of the Manager, adversely affect the title, property or rights of any Entitled Party thereto.  Without limiting the generality of this Section 4.2, the Manager shall be required to pay or discharge any Lien Claim (1) that results from an act or omission by the Manager with respect to which the Manager would not be entitled to indemnification pursuant to Section 16 hereof (“Manager Malfeasance”) or (2) if prior to such payment or discharge, the Manager receives from the Issuer the amount thereof (the “Owner Lien Claim Amount”).  If any Lien Claim shall have resulted from Manager Malfeasance and shall have been paid by the Issuer, whether directly or by payment of the Owner Lien Claim Amount to the Manager, then, in either case, the Manager shall promptly reimburse the Issuer, upon presentation of an invoice therefor.

5.             DUTIES/RIGHTS OF THE MANAGER

5.1           Duties of the Manager.  Subject to the terms and provisions hereof, the Manager shall provide the services specified in this Section 5 to, and on behalf of, the Issuer during the Management Term with respect to the Owner Compressors. The parties hereto acknowledge and agree that, if an

3

Owner Compressor is then subject to a User Contract, the User under such User Contract may provide certain of the obligations set forth in Sections 5.6, 5.7, 5.8 and 5.9 hereof; provided, however, that as long as UCI or a Universal Affiliate is the Manager hereunder, UCI shall remain the primary obligor of all such obligations and liable for any breaches thereof.

5.2           Marketing.

(a)           During the Management Term, Manager shall market, service, maintain, operate and provide contract compression services for the Owner Compressors consistent with the Services Standard.  In addition, for so long as UCI or a Universal Affiliate is the Manager, UCI or such Universal Affiliate shall keep the Owner Compressors under User Contracts subject to the same utilization rates and contract rates and in the same manner as Other UCI Compressors.  In addition, the Manager shall, consistent with the Services Standard, negotiate the terms and conditions of all User Contracts; provided that the terms and conditions of such User Contracts must be consistent with those of User Contracts for Other UCI Compressors (or, if the Manager is not UCI or a Universal Affiliate, any Compressors or equipment of a type similar to the Owner Compressors, for which contract compression services are provided, operated or managed by such Manager for its own account and third parties other than the Issuer) and, in any event, must comply with (i) then generally accepted industry standards, (ii) for so long as the Manager is UCI or a Universal Affiliate, the terms of the Contribution Agreement and (iii) the requirements of the Related Documents.  The Manager shall market, operate, provide contract compression services for and maintain the Owner Compressors in compliance with the Services Standard and using such efforts which are at least equal to the efforts used by the Manager (or any appointed subcontractor) with respect to (x) if the Manager is UCI or any Universal Affiliate, the Other UCI Compressors, and (y) if the Manager is not UCI or any Universal Affiliate, any Compressors or equipment of a type similar to the Compressors owned, managed, operated or for which contract compression services are provided by the Manager (or any appointed subcontractor) for its own account and third parties other than the Issuer.

(b)           In performing its marketing duties pursuant to this Section 5.2, UCI shall use its best efforts to comply with the applicable concentration limits set forth in Appendix A to the Indenture in the definitions  of Excess 99 hp Amount, Excess 299 hp Amount, Excess 599 hp Amount, Excess 999 hp Amount and Excess Customer Concentration Amount.

5.3           Contract and Administration Obligations.  The Manager shall, consistent with the Services Standard, cause to be performed when due, on behalf of the Issuer, all of the Issuer’s performance obligations under the User Contracts and the other Related Documents to which the Issuer is a party; provided, however, that nothing contained herein shall be construed as creating credit recourse to the Manager for (i) principal, interest or premium payments on the Notes or (ii) indemnification payments otherwise the obligation of the Issuer pursuant to the Related Documents (except to the extent that the Manager would otherwise be liable for such indemnification payment pursuant to the provisions of Section 16 hereof).

5.4           Billing and Other Information.  During the Management Term, the Manager shall ▇▇▇▇, on behalf of the Issuer, for all contract payments and other sums due to the Issuer with respect to those Owner Compressors then subject to a User Contract and shall also be responsible for the collection thereof.  Such bills may be prepared in summary format for all Compressors for which contract compression services are provided to a User, but shall contain a detailed listing of each Compressor so contracted.

4

5.5           Defaults by Users; Contract Amendments and Waiver.

(a)           In the event of any breach or default by a User under a User Contract, the Manager shall, consistent with the Services Standard, take appropriate remedial action, in the name of the Issuer, with respect to such defaulted User Contract including, without limitation, (i) the termination of such User Contract as to any or all Owner Compressors subject thereto, (ii) the recovery of possession of any or all Owner Compressors subject thereto and (iii) the enforcement of any other rights or remedies of the Issuer under such User Contract, including, without limitation, the right to payment for any contract compression services or payment of other amounts owed by such User under such User Contract. In furtherance of the foregoing, the Manager shall, consistent with the Services Standard, (i) institute and prosecute such legal proceedings in the name of the Issuer as is permitted by Applicable Law in order to accomplish the foregoing, (ii) settle, compromise and/or terminate such proceedings or (iii) reinstate such User Contract; provided that the Manager shall not be required to take any such action if, in the exercise of its reasonable commercial judgment, the Manager would not take such action if such Owner Compressors were Other UCI Compressors (or, if the Manager is not UCI or a Universal Affiliate, Compressors or equipment of a type similar to the Compressors that is owned,  managed, maintained, operated or for which contract compression services are provided by such Manager for its own account and third parties other than the Issuer).  All amounts expended by the Manager in performing its obligations pursuant to the provisions of this Section 5.5, after reduction of such amounts for enforcement costs actually received by the Manager pursuant to the terms of the related User Contracts, shall be a Reimbursable Service.  The Issuer reserves the right to take, upon written notice to the Manager, in its sole discretion, any or all of the actions described in this Section 5.5 directly in its own name and on its own behalf.  In such an event the Manager, at the Issuer’s expense, shall cooperate with the Issuer (or its designee or assignee) and provide the Issuer (or its designee or assignee) with such assistance as the Issuer may reasonably request.

(b)           In performing its obligations hereunder, the Manager may, acting in the name of the Issuer and without the necessity of obtaining the prior consent of the Issuer or any Entitled Party, grant consents or enter into and grant modifications, waivers and amendments to the terms of any User Contract except for consents, modifications, waivers or amendments that (x) are inconsistent with the Services Standard or (y) contravene (or permit the contravention of) any provision of the Indenture (including without limitation, Sections 636 through 649 thereof).

5.6           Maintenance; Manager’s Expenses.

(a)           The Manager shall, consistent with the Services Standard, cause the Owner Compressors to be maintained in good operating order and condition. The standard for such maintenance shall be the highest of the following:  (i) any standard required or set forth for the Owner Compressors by Applicable Law, (ii) the Services Standard, and (iii) with respect to the Owner Compressors provided to any User, any standard set forth in the related User Contract.  All amounts expended by the Manager for maintenance (other than an overhaul made in compliance with Section 5.6(b) hereof) of the Owner Compressors, after reduction of such amounts for maintenance payments actually received by the Manager pursuant to the terms of any related User Contract, shall be at the expense of the Manager.

(b)           The Manager shall conduct, or cause to be conducted, overhauls of the Owner Compressors at such intervals and in such detail as it conducts overhauls of the Other UCI Compressors (or, if the Manager is not UCI or a Universal Affiliate, Compressors or equipment of a type similar to the Compressors that is owned, maintained, operated, managed or for which contract compression services are provided by such Manager for its own account and third parties other than the Issuer).

5

(c)           Maintenance, modifying, repackaging and/or overhauls of the Owner Compressors may be performed by the Manager or third parties as reasonably determined by the Manager. For maintenance, modifying, repackaging and/or overhauls of the Owner Compressor(s), the Issuer will pay for (i) materials, supplies and parts at the Manager’s actual out-of-pocket cost therefor and (ii) labor at hourly rates established by the Manager from time to time; provided that such costs and rates are reasonable and consistent with industry expenses for such services (the sum of (i) and (ii), an “Overhaul Fee”).  Such hourly rates shall be based upon the Manager’s direct costs of labor plus amounts for the Manager’s plant or facility overhead based on the Manager’s job cost system for allocating overhead.

5.7           Insurance.

(a)           The Manager will cause to be carried and maintained, at its sole expense, with respect to all Owner Compressors at all times during the Management Term thereof and for the geographic area in which any Owner Compressor is at any time located (i) physical damage insurance insuring against risks of physical loss or damage to the Owner Compressors (“Property Insurance”) with an aggregate annual loss limit of  not less than $20,000,000 per occurrence except for certain perils which have sub-limits in the amounts set forth on Schedule 5.7(a) attached hereof, and (ii) liability insurance against liability for bodily injury, death and property damage resulting from the use and operation of the Owner Compressors (“Liability Insurance”) with an aggregate loss limit of not less than $20,000,000 per occurrence except for certain perils which have sub-limits in the amounts set forth on Schedule 5.7(a) hereof and in each case shall be on terms consistent with current practices; provided, however, that if by reason of a force majeure event or other event outside of the control of the Manager, one or more of the terms of such insurance as required hereby are not available in the commercial insurance markets on commercially reasonable terms, the Manager shall nevertheless be deemed to have complied with this Section 5.7 if the Manager obtains such insurance on commercially reasonable terms then available to the Manager with such premiums, deductibles and policy limits that are consistent with industry standards which are reasonably satisfactory to each Series Enhancer.  Property Insurance and Liability Insurance shall be subject to deductibles that are consistent with industry standards.  The policies of insurance required under this Section 5.7(a) shall be valid and enforceable policies issued by insurers having an A.M. Best Company general policyholder rating of “A-” and a financial rating of “IX” or in each case better or otherwise acceptable to each Series Enhancer and shall provide coverage with respect to incidents occurring anywhere in the United States.

(b)           Such Property Insurance policy or policies will name the Issuer, each Series Enhancer and the Indenture Trustee, individually and on behalf of the Entitled Parties, as the loss payees, as their respective interest may appear.  Such Liability Insurance policy or policies will name the Issuer, each Series Enhancer and the Indenture Trustee, individually and on behalf of the Entitled Parties, as additional insureds (each an “Additional Insured”).  Each such policy shall provide that (i) the insurers waive any claim for premiums and any right of subrogation or setoff against Additional Insureds, (ii) it may not be invalidated against any Additional Insured by reason of any violation of a condition or breach of warranty of the policies or the application therefor by Manager or the Issuer, (iii) it may be canceled by the insurer only after no less than ten (10) days’ prior written notice from the Manager’s insurance broker to Indenture Trustee and each Series Enhancer, and (iv) the insurer will give written notice to Indenture Trustee and each Series Enhancer in the event of nonpayment of premium by the Manager when due.

(c)           On the Closing Date, and thereafter not less than five (5) days prior to the expiration dates of any expiring policies required under this Section 5.7, the Manager shall furnish the Indenture Trustee and each Series Enhancer with certificates of the insurance or replacement insurance coverage required by this Section 5.7.

6

(d)           Any deductibles or losses that are not covered by either the Property Insurance or Liability Insurance shall be paid by, and for the account, of the Manager.  The Manager agrees to promptly, but in any event within three (3) Business Days after receipt of proceeds of such loss, deposit such amounts into the Trust Account or the Purchase Account, as applicable, in accordance with Section 302(b) of the Indenture for distribution in accordance with Section 302 of the Indenture.

5.8           Taxes.  The Manager shall cause to be paid when due, and will indemnify each Entitled Party from and against, all local, state, federal and foreign personal property, sales or use taxes, license fees, assessments, charges, fines, interest and penalties (all such taxes, license fees, assessments, charges, fines, interest and penalties being hereinafter called “Impositions”) hereafter levied or imposed upon any Entitled Party, in connection with or measured by the possession, contract for services, use or operation of any Owner Compressors but excluding any federal, state or local tax calculated based on the taxable income of the applicable Entitled Party.  The Manager (whether such Manager is UCI or a Universal Affiliate or a Replacement Manager) will promptly remit all Excluded Payments received by it pursuant to Section 302(c), Section 302(d)(2) or 302(e)(2) of the Indenture to the relevant taxing authority.  The Manager will also pay (if the Manager is not UCI or a Universal Affiliate, such payments will be paid pursuant to a distribution under Section 302 of the Indenture) all Impositions that might in any way affect the title of the Issuer, or result in a Lien upon any Owner Compressors or result in a Material Adverse Change, in each case, before the same shall become delinquent; provided, however, that the Manager shall not be required to pay any Imposition of any kind so long as it is contesting such Imposition in good faith and by appropriate legal proceedings, provided, further, that the nonpayment thereof shall not, in the reasonable opinion of the Manager, adversely affect the title, property or rights of the Issuer. In the event any reports or returns with respect to Impositions are required to be filed, the Manager will prepare and file such reports or returns, or cause such reports or returns to be prepared and filed, in such manner as to show the interests of the Issuer in the Owner Compressors.

5.9           Compliance with Law.  The Manager, at the expense of the Issuer, shall, consistent with the Services Standard, cause the Owner Compressors to comply, and each User Contract entered into or renewed after the date hereof shall require the User thereunder to comply, in all material respects with all Applicable Laws and Section 604 of the Indenture.   In the event that such Applicable Laws require any alteration of an Owner Compressor, or in the event that any equipment or appliance of an Owner Compressor shall be required to be changed or replaced, or in the event that any additional or other equipment or appliance is required to be installed on an Owner Compressor in order to materially comply with such Applicable Laws, the Manager, at the expense of the Issuer, shall make such alteration, change, replacement or addition (a “Mandatory Alteration”); provided, however, that the Manager, in good faith, shall contest the validity or application of any such Applicable Law which it would have contested if the affected Owner Compressor had been an Other UCI Compressor (or, if the Manager is not UCI or any Universal Affiliate, any Compressors or equipment of a type similar to the Compressors owned, managed, operated or for which contract compression services are provided by the Manager (or any appointed subcontractor) for its own account and third parties other than the Issuer), in any reasonable manner which does not, in the opinion of the Manager, adversely affect the title, property or rights of the Issuer.

5.10         Records and Information.  The Manager shall, consistent with the Services Standard, maintain separate, complete and accurate records relating to the Owner Compressors and all matters covered by this Agreement in the same form and to the same extent as the Manager customarily maintains records in respect of the Other UCI Compressors (or, if the Manager is not UCI or any Universal Affiliate, any Compressors or equipment of a type similar to the Compressors owned, managed, operated or for which contract compression services are provided by the Manager (or any appointed subcontractor) for its own account and third parties other than the Issuer).  The Manager shall promptly, upon request of  the Issuer or any Series Enhancer, deliver to the Issuer, such Series Enhancer or any designee of any of

7

the foregoing such records. Upon request, the Manager shall promptly supply the Issuer with all information necessary for the Issuer to prepare all reports required of the Issuer under the Related Documents.

5.11         User Contract.  The Manager shall store at its offices at ▇▇▇▇ ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇, all User Contracts and all compression services documents related thereto, including without limitation, the related Contract File, in a locked, fire retardant storage facility.  The Manager shall provide the Issuer, the Indenture Trustee and each Series Enhancer thirty (30) days prior written notice of a change in the location of Manager’s offices which shall include the relocation address.  Within ninety (90) days after the Closing Date (or, in the case of any Owner Compressor acquired by the Issuer after the Closing Date, within thirty (30) days after the related Contribution Date or Substitution Date), the Manager shall stamp Schedule A (or the appropriate counterpart of Schedule A or the appropriate schedule of equipment attached to each User Contract) of each User Contract relating to an Owner Compressor acquired by the Issuer on the Closing Date or any subsequent Contribution Date or Substitution Date to indicate the Indenture Trustee’s security interest in such User Contract.

5.12         Other Services.  The Manager shall be responsible for the provision of such other services incidental to the foregoing as may from time to time be required under the User Contracts and other Related Documents or may be reasonably necessary in connection with the ownership, maintenance, and the Domestic Contract Compression Business of the Owner Compressors.

5.13         Mutual Maintenance and Servicing.  So long as the Manager is UCI or a Universal Affiliate, the Manager and the Issuer agree that in order for the Manager to provide mutually beneficial maintenance and servicing of the Owner Compressors in the same manner as it maintains and provides for the Other UCI Compressors, the Manager is permitted to use parts, engines, inventory or supplies from (x) Other UCI Compressors to service and maintain the Owner Compressors and the Other UCI Compressors, and (y) Owner Compressors to service and maintain the Owner Compressors and the Other UCI Compressors, in all instances in accordance with Sections 2.2 and 2.3 hereof and in the normal and customary business practices of the Manager; provided however, in the event any Owner Compressor is utilized for parts in accordance with the foregoing mutual maintenance and servicing provisions, such Owner Compressor, to the extent not repaired, replaced or rebuilt by the end of the calendar month in which such parts or engines were utilized, will become an Ineligible Compressor.  The Manager will have the option to replace such Ineligible Compressor with another Compressor of equal or greater value (based on and subject to the criteria set forth in Section 3.04 of the Contribution Agreement) as the Ineligible Compressor by the end of the calendar month in which such utilization of parts or engines first occurred.  To the extent the Compressor added in replacement of any such Ineligible Compressor exceeds the value of such Ineligible Compressor, an appropriate adjustment to approximate such excess value shall be made for the benefit of the Manager to the Operations Fee and Overhaul Fee.  The Issuer and the Manager acknowledge and agree that each party derives independent and mutual benefit from this maintenance and servicing arrangement set forth in this Section 5.13.

5.14         Purchase Account.  Subject to the conditions, covenants and agreements set forth in Section 315 of the Indenture, the Manager and the Issuer agree that the Manager shall (a) remit, or shall cause to be remitted, any and all Compressor Reinvestment Sales Proceeds to the Purchase Account, (b) use, or shall cause the use of, all or any portion of the Compressor Reinvestment Sales Proceeds on deposit in the Purchase Account to purchase Additional Compressors, and (c) direct, or shall cause the direction of, the Indenture Trustee to liquidate as necessary any and all Eligible Investments credited to the Purchase Account and to transfer from the Purchase Account to the Trust Account, (i) in accordance with, and at the times required by, Section 315(c) of the Indenture, any unused portion of such Compressor Reinvestment Sales Proceeds and (ii) in accordance with, and at the times required by, Section 315(d) of the Indenture, all funds in the Purchase Account.

6.             AUTHORITY AND CONSENTS.

6.1           Issuer.  The Issuer confers on the Manager all such authorities and grants all such consents as may be necessary for the Manager’s performance of its duties under this Agreement, and will, at the request of the Manager, confirm any such authorities and consents to any third parties, execute such other documents and do such other things as the Manager may reasonably request for the purpose of giving full effect to this Agreement and enabling the Manager to carry out its duties hereunder.

6.2           Manager Default.  After the occurrence and during the continuance of a Manager Default, the Manager irrevocably, and by way of security to the Issuer for the obligations of the Manager herein, appoints the Issuer or the Issuer’s designee (which shall be the Indenture Trustee so long as any Outstanding Obligations remain unpaid) to be its attorney-in-fact with full power of substitution on behalf of the Manager and in its name or otherwise to execute any documents contemplated by this Agreement and any Related Document, and to give any notice and to do any act or thing which the Manager is obliged to execute or do under this Agreement and any Related Document.  The Manager hereby confirms and agrees to ratify and confirm whatever any such attorney shall do or propose to do in the exercise or purported exercise of all or any of the powers, authorities and discretion referred to in this paragraph.

7.             ACCOUNTS AND PAYMENTS

7.1           Lockbox Accounts.

(a)           On or prior to the Closing Date, the Lockbox Account shall have been established and shall be under the exclusive control of the Intercreditor Collateral Agent, and UCI, as Manager, shall, or shall cause, all Collections related to its Domestic Contract Compression Business to be deposited in the Lockbox Account, in each case, in accordance with the terms of the Intercreditor Agreement and the Letter Agreement.  So long as the Manager is UCI or a Universal Affiliate, UCI shall comply with its obligations and duties under the Intercreditor Agreement and the Letter Agreement.  Immediately after the completion of such daily allocation, all Collections allocable to the Securitization Collateral will be transferred to the Trust Account.

(b)           During the continuation of a Trigger Event, the Manager shall, on a weekly basis, provide to the Issuer, each Series Enhancer and the Indenture Trustee a copy of each daily cash reconciliation prepared during the preceding week.  At any time during the continuation of a Trigger Event, each of the Issuer, each Series Enhancer and the Indenture Trustee and their respective accountants and attorneys shall be entitled, at the expense of the Manager, to visit the Manager’s office and conduct a review of all backup documentation supporting the daily cash allocation report.

(c)           Upon an Event of Default or a Manager Default and the continuation of such event, as the case may be, the Back-up Manager and the Requisite Global Majority (or their designees), are each hereby authorized and empowered, as the Issuer’s attorney-in-fact, to endorse any contract compression payments relating to an Owner Compressor deposited in a lockbox or presented for deposit in any lockbox account requiring the endorsement of the Issuer, which authorization is coupled with an interest.

11.2         S&A Fee.

(a)           The selling and administration fee payable to UCI as initial Manager for each Collection Period (or any portion thereof) shall be the product of (i) the Monthly S&A Fee Rate and (ii) Gross Compressor Contract Revenues actually received by the Manager during such Collection Period (such product, the “UCI S&A Fee”).  The S&A Fee for any Manager other than UCI or any Universal Affiliate shall be the amount calculated in accordance with the definition thereof, subject to the adjustments and limitations contained therein and herein.

(b)           The monthly selling and administration fee rate during the first year following the Closing Date shall be six percent (6%), which percentage shall be adjusted annually thereafter in accordance with the provisions of Section 11.2(c) (the “Monthly S&A Fee Rate”).

(c)           The Monthly S&A Fee Rate may be recomputed by the Manager or any Replacement Manager and automatically adjusted each year, prior to a Trigger Event, on the last day of the quarter following the Manager’s fiscal year end, to reflect the actual selling and administrative costs

incurred by the Manager to manage the UCI Compressors during such fiscal year.  Any such adjustment shall be accompanied by a certification by the Manager that any increase in the Monthly S&A Fee Rate reflects increases in selling and administrative costs which are also being incurred in respect of all of the UCI Compressors. The reasonableness of the amount of such cost increase will, at the request of any Entitled Party, be verified by a third party consultant selected by the Requisite Global Majority and reasonably satisfactory to the Manager.  Increases in the S&A Fee in excess of the levels permitted in the definition of S&A Fee shall be payable at a subordinated level in accordance with Sections 302(d) and (e) of the Indenture.  In addition to the adjustment set forth above, the Monthly S&A Fee Rate may be adjusted with the prior consent of the Manager, the Issuer, and the Requisite Global Majority to reflect material non-recurring costs incurred in any year.

(b)           The Operations Fee Rate may be recomputed by UCI and automatically adjusted each year, prior to a Trigger Event, on the last day of the quarter following the Manager’s fiscal year end, to reflect the actual operating costs incurred by the Manager to manage the UCI Compressors during such fiscal year then ended.  Any such adjustment shall be accompanied by a certification by the Manager that any increase in the Operations Fee Rate reflects increases in costs which are also being incurred in respect of all of the UCI Compressors. The reasonableness of the amount of such cost increase will, at the request of any Entitled Party, be verified by a third party consultant selected by the Requisite Global Majority and reasonably satisfactory to the Manager.  Increases in the Operations Fee in excess of the levels permitted in the definition of Operations Fee shall be payable at a subordinated level in accordance with Sections 302(d) and (e) of the Indenture.  In addition to the adjustment set forth above, the Monthly Operations Fee Rate may be adjusted with the prior consent of the Manager, the Issuer, and the Requisite Global Majority to reflect material non-recurring costs incurred in any year.

Credit and Collection Policies

[Section 9.1(e)]

21.          CREDIT/COLLECTION GUIDELINES

21.1        CREDIT

•      ALL new customers should complete and sign a standard account application.  No Account Number will be assigned until completed.

•      When received, if potential sale is over $2,500, pull a credit report according to location. (If under $2,500, manually check a minimum of four trade references   Four bureaus are available, NACM — Houston and Dallas, Experian, and Dun & Bradstreet. For sales over $2,500, if insufficient information is available from the credit bureaus, manually check the trade and bank references.  Again, there should be a minimum of four trade references.

•      Evaluate credit worthiness based on trade payment history, length of time in business, and overall financial condition and ability to repay.

•      Any customer with a trend towards slow pay, a high debt ratio, and/or start ups may be approved with A/R Manager Approval  and may require a down payment.  Contract deposits are normally the equivalent of two months while parts deposit vary from 30 – 50% based upon whether it is a special order.

•      Credit representatives have approval authority up to $25,000.  Anything above this must be referred to manager.  Approval authority is assigned by the Vice President — Financial Services and is based on level of experience of employees.  Any Credit Limit over $1 million must be approved by the Vice President — Financial Services.

•      Once account is approved (or declined) an account number will  be assigned in the system and a customer file  will be made by  whom ever completes the credit investigation.

•      If customer is tax exempt, enter into system.

•      Advise salesperson of decision via telephone or email.

•      If an account has had no activity in over one year, a complete inquiry should be done by the credit representative responsible for that account to determine continued ability to repay. This consists of pulling an updated credit bureau and rechecking references.

•      Monthly a list of “Problem” Accounts will be forwarded to the Sales Departments. Additional sales should not be approved until the problem is addressed satisfactorily.

•      If a customer wishes to purchase and/or contract in an amount that would put them over their credit limit, an inquiry should be done to determine if their credit limit could be raised. Limits are raised based on previous pay history with UCI and information obtained from an updated credit report.  This

1

is done by the credit representative responsible for the account or, based on the amount of the sale, the credit manager or Vice President – Financial Services.

•      If there are any questions regarding these, please contact the Credit Manager for clarification.

21.2        COLLECTIONS – Over $10,000 (Under $10,000 Pending)

•      Collections are done from an aging report that is divided among the collectors.

•      Calls are made according to individual collectors preference.  However, any account with a balance over $10,000 must be contacted when it reaches 45 days outstanding and BEFORE it reaches 60 days outstanding.  This information is included in a report to manager due by the 3^rd working day of each month and is updated monthly.  This report is  reviewed by the A/R Manager and the Vice President – Financial Services and is forwarded to both sales and the district managers.

•      When customer is contacted, all pertinent information should be entered into the customer notes section of the customer master.   Information such as faxes sent, money promised, as well as follow up dates need to be entered.   The collectors initials MUST always be included and the note should include sufficient information to stand on its own.  This information is reviewed by the manager and is included in  the monthly over $10,000/over 60 day report.

•      Statements are to go out by the 4^th working day of the month.  Collectors should go through the statements individually, highlighting past due items, etc.  Use this as an opportunity to bring these items to the customer’s attention.

•      Calls received by customers are to be responded to as soon as possible, but no longer that 24 hours from the time the call is received.  Requests for faxed copies, etc. should be handled in the same manner.

•      Customer calls regarding invoice problems not collection related need to be directed to the appropriate person right away.   This information should be relayed in writing (fax, e-mail, interoffice mail, etc.).   Notes indicating who is handling the account need to be made in C3.

•      If a customer has missed two payments or has a balance outstanding more than 60 days, with no response to collection efforts, a Customer Collection Form MUST be completed by the collector, approved by the A/R Manager and forwarded via email to the salesman.  A copy of the form is to be printed and placed in an active file by date.  The salesman will be expected to contact their customer to try to obtain payment.  Any resolution should be noted on the Customer Collection Form which would be removed from the active file and placed in the customer folder.

•      For any Customer Collection form for which remains in the Active File after 10 business days, the following will be sent to the customer:

•      For contract units, a letter warning that the machine(s) will be disabled will be sent by certified mail.  .

•      For Parts & Service / Fabrication, a “10 Day” Demand Letter.

Any Customer reaching this point will have their Account placed on hold, preventing further sales until the account is cleared.

•      Contract Compression - Upon  reaching 90 days outstanding with no payment or satisfactory resolution, a “Disable Unit” Form is sent via an email to the district manager and the Regional Sales

2

manager.  They will then contact the appropriate field personnel who go the lease site and remove the magneto from the compressor, rendering it inoperable.  If, after 30 days, payment still has not been received, or appropriate arrangements made, the unit will be removed from the lease. The District Manager will contact the Area Supervisor and advise them to schedule the pick up and removal of the unit.  This can usually be done within a one week period.

•      Parts/Service – Upon  reaching 90 days outstanding with no payment or satisfactory resolution, appropriate action will be taken (filing in small claims, placing for collection with an agency, etc.) A report showing these items and their status will be maintained by the Credit Manager and Reviewed by the Vice President — Financial Services at least monthly.

•      A copy of the Disable Unit Form is placed in a Disabled Unit File until resolved or removed from the lease, and then filed in the customer file.  A report showing all units currently recommended to be disabled, and their status will be sent to the Vice President – Financial Services and the CFO on the last day of each month.

•      Liens will also be filed on the contract at 90 days outstanding   The credit manager will  handle this process.  Paperwork is prepared and filed in the appropriate county and/or parish.  Laws and forms are provided using the LienWrite software package.  Filing of the lien, in most cases, can be done within a two week period.  (Most states allow 6 months from the last date of service to file.)    From here, the account is handled by the credit manager who will work on getting payment by using the lien process, pursuing judgment, etc.  If efforts still fail, the balance will be sent to an outside collection agency or referred to UCI’s legal department for further action.

•      If a customer requests payment terms or extensions due to cash flow problems, we will normally try to work with them as they stay in contact and promised payments are received.  Any payment plan must be in writing with terms clearly spelled out.  It must be signed by both parties and should allow for further legal action should the customer default.

•      Collector performance is measured by the total number of accounts of their responsibility are over 60 days past due, as well as total number of dollars over 60 days past due.
