The Person that is so notified shall be referred to herein as the “Offeree.” Such notice shall include an offer (the “Offer”) by the Acquiring Party to sell the Acquired Exterran Restricted Business or the Acquired Partnership Restricted Business, as the case may be (the “Offered Assets”), to the Offeree, together with a proposed definitive agreement to effectuate the purchase and sale of the Offered Assets (the “Purchase Agreement”). The Offer shall set forth the Acquiring Party’s proposed terms relating to the sale of the Offered Assets to the Offeree, including the purchase price, any liabilities to be assumed by the Offeree as part of the Offer and the other terms of the Offer; provided, that the representations and warranties regarding the Offered Assets and the indemnification provision contained in the Purchase Agreement shall be substantially consistent with the terms contained in the definitive purchase agreement pursuant to which the Acquiring Party acquired the Offered Assets or the entity that owned the Offered Assets, subject to such adjustments that the Acquiring Party reasonably determines are necessary to reflect the differences in the transaction.

(b) As soon as practicable after the Offer is made, the Acquiring Party will deliver to the Offeree all information prepared by or on behalf of or in the possession of such Acquiring Party relating to the Offered Assets and reasonably requested by the

Offeree. As soon as practicable, but in any event, within 60 days after receipt of the notification called for in Section 2.4(a), the Offeree shall notify the Acquiring Party in writing that either:

(i) the Offeree (with the concurrence of the Conflicts Committee if the Offeree is the Partnership) has elected not to purchase (or not to cause any of its Subsidiaries to purchase) any of such Offered Assets; or

(ii) the Offeree (with the concurrence of the Conflicts Committee if the Offeree is the Partnership) has elected to purchase (or to cause any of its Subsidiaries to purchase) all of such Offered Assets; provided, that if the Offeree is the Partnership, and in the opinion of outside counsel to the Partnership Entities, less than 90% of the gross income from the operations of such Offered Assets consists of “qualifying income” under Section 7704 of the Code (such portion of such Offered Assets that does not so qualify being referred to herein as the “Non-Qualifying Business”), then the Partnership (with the concurrence of the Conflicts Committee) may condition its obligation to purchase the Non-Qualifying Business (but not the portion of the Offered Assets that do not constitute the Non-Qualifying Business (the “Qualifying Business”)) on the conversion of the agreements pursuant to which the Non-Qualifying Business provides Competitive Services to its customers to agreements substantively similar to the Form Compression Services Agreement from a federal income tax treatment perspective (from the Partnership’s perspective) and otherwise having substantially the same economic terms as the agreements being converted (the “Conversion Condition”); provided further, that in such event, each of the Exterran Entities and the Partnership Entities shall use commercially reasonable efforts to satisfy the Conversion Condition as soon as commercially practicable. If the Offeree elects to purchase the Offered Assets, the following procedures shall be followed:

A. After the receipt of the Offer by the Offeree, the Acquiring Party and the Offeree shall negotiate in good faith the fair market value of the Offered Assets that are subject to the Offer (including the specific fair market value of any Offered Assets that constitute a Non-Qualifying Business) and the other terms of the Offer on which the Offered Assets will be sold to the Offeree. If the Acquiring Party and the Offeree agree (with the concurrence of the Conflicts Committee) on the fair market value of the Offered Assets that are subject to the Offer and the other terms of the Offer during the 30-day period (the “Offer Period”) after receipt by the Acquiring Party of the Offeree’s election to purchase (or to cause any Subsidiary of the Offeree to purchase) the Offered Assets, the Offeree shall purchase (or cause any of its Subsidiaries to purchase) and the Acquiring Party shall sell the Offered Assets on such terms as soon as commercially practicable after such agreement has been reached, which obligation may require such parties to consummate the purchase and sale of the Qualifying Business prior to satisfaction of the Conversion Condition.

B. If the Acquiring Party and the Offeree are unable to agree on the fair market value of the Offered Assets that are subject to the Offer or on any other terms of the Offer during the Offer Period, the Acquiring Party and the Offeree will engage an independent investment banking firm prior to the end of the Offer Period to determine the fair market value of the Offered Assets (including the specific fair market value of any Offered Assets that constitute a Non-Qualifying Business) and/or the other terms on which the Acquiring Party and the Offeree are unable to agree. In determining the fair market value and other terms on which the Offered Assets are to be sold, the investment banking firm will have access to the proposed sale and purchase values and terms for the Offer submitted by the Acquiring Party and the Offeree, respectively, and to all information prepared by or on behalf of the Acquiring Party relating to the Offered Assets and reasonably requested by the investment banking firm. In determining the terms on which the Offered Assets are to be sold (other than the fair market value of the Offered Assets), the investment banking firm shall give substantial weight to the terms contained in the definitive purchase agreement pursuant to which the Acquiring Party acquired the Offered Assets or the entity that owned the Offered Assets. Such investment banking firm will determine the fair market value of the Offered Assets and/or the other terms on which the Acquiring Party and the Offeree are unable to agree within 60 days of its engagement and furnish the Acquiring Party and the Offeree its determination. The fees and expenses of the investment banking firm will be divided equally between the Acquiring Party and the Offeree. Upon receipt of such determination, the Offeree will have the option, but not the obligation, to (with the concurrence of the Conflicts Committee if the Offeree is the Partnership):

1. purchase the Offered Assets on such terms as determined above; or

2. elect not to purchase such Offered Assets.

If the Offeree elects to so purchase the Offered Assets, the Offeree shall purchase (or cause any of its Subsidiaries to purchase) and the Acquiring Party shall sell the Offered Assets on such terms as soon as commercially practicable after such agreement has been reached, which obligation may require such parties to consummate the purchase and sale of the Qualifying Business prior to satisfaction of the Conversion Condition.

2.5 Scope of the Prohibition. Except as provided in this Article II, each of the Parties shall be free to engage (whether directly or through the acquisition of or investment in equity or debt interests in any Person) in any business activity whatsoever, including those that may be in direct competition with any of the other Parties.

2.6 New Customers. The Parties agree that any offer by any of the Parties hereto to provide Competitive Services to New Customers in any state or territory of the United States shall be first made on behalf of the Partnership Entities and shall include an offer to provide such Competitive Services under an agreement substantially in the form of the Form Compression Services Agreement. If the New Customer is unwilling to enter into an agreement with a Partnership Entity that is substantively similar to the Form Compression Services Agreement from a federal income tax treatment perspective (from the Partnership’s perspective), an Exterran Entity may enter into an agreement to provide Competitive Services to such New Customer for its own account provided that any agreement between such Exterran Entity and such New Customer is not substantively similar to the Form Compression Services Agreement from a federal income tax treatment perspective (from the Partnership’s perspective). If a New Customer enters into an agreement with a member of the Partnership Group for Competitive Services, then such New Customer will then constitute a Partnership Customer for the purposes of this Agreement and if, in accordance with this Section 2.6, a New Customer enters into an agreement with an Exterran Entity for Competitive Services, then such New Customer will then constitute an Exterran Customer for the purposes of this Agreement.

2.7 Enforcement. Each Party agrees and acknowledges that the other Parties hereto do not have an adequate remedy at law for the breach by such Party of the covenants and agreements set forth in this Article II, and that any breach by such Party of the covenants and agreements set forth in this Article II would result in irreparable harm to the other Parties hereto. Each Party further agrees and acknowledges that the other Parties hereto may, in addition to the other remedies that may be available to the other Parties hereto, file a suit in equity to enjoin such Party from such breach, and consents to the issuance of injunctive relief under this Agreement.

2.8 Termination. Unless this Agreement has otherwise terminated pursuant to Section 8.4, this Article II shall terminate on the third anniversary of the Effective Date. In addition, unless this Agreement has otherwise been terminated pursuant to Section 8.4 or this Article II has otherwise been terminated pursuant to the first sentence of this Section 2.8, Sections 2.1, 2.2, 2.3, 2.4 and 2.6 shall terminate upon a Change of Control of Exterran. Unless this Agreement has otherwise terminated pursuant to Section 8.4 or this Article II has terminated pursuant to the first sentence of this Section 2.8, and in the event that Sections 2.1, 2.2, 2.3, 2.4 and 2.6 terminate pursuant to the immediately preceding sentence, without the prior written approval of the Conflicts Committee, the Exterran Entities shall be prohibited from providing (whether directly or through the acquisition of or investment in equity or debt securities of any Person) Competitive Services to a particular Partnership Customer at the particular Site at which the Partnership Group was providing Competitive Services to such Partnership Customer on the date of the Change of Control of Exterran.

ARTICLE III
SERVICES

3.1 Provision, Allocation and Reimbursement for Services

(a) Subject to Article V, the Exterran Entities shall, upon the reasonable request of the General Partner, provide the Partnership Group with all personnel and

services reasonably necessary to run the business of the Partnership Group, which services may include, without limitation, those services set forth on Schedule 3.1(a) (collectively, the “Services”). For the avoidance of doubt, the Services shall not include the services described on Schedule 3.1(b). These Services shall be substantially similar in nature to the services of such type previously provided by the Exterran Entities in connection with their management and operation of the Partnership Assets and any other assets of a similar nature directly or indirectly conveyed, contributed or otherwise transferred to the Partnership Group, in each case during the 12-month period prior to such transfer.

(b) The Exterran Entities shall provide the Services to the Partnership Group in a manner that is in the good faith judgment of Exterran commercially reasonable; provided, that for so long as the Exterran Entities exercise at least the same degree of care, skill and prudence in providing the Services as customarily exercised by it for its own operation of the USCSB, then Exterran will be deemed to have provided such Services in a commercially reasonable manner. EXCEPT AS SET FORTH IN THE PRECEDING SENTENCE, THE EXTERRAN ENTITIES MAKE NO (AND HEREBY DISCLAIM AND NEGATE ANY AND ALL) WARRANTIES OR REPRESENTATIONS WHATSOEVER, EXPRESS OR IMPLIED, WITH RESPECT TO THE SERVICES. IN NO EVENT SHALL ANY EXTERRAN ENTITY OR ANY OF THEIR AFFILIATES BE LIABLE TO ANY MEMBER OF THE PARTNERSHIP GROUP OR TO ANY OTHER PERSON FOR ANY EXEMPLARY, PUNITIVE, INDIRECT, INCIDENTAL, CONSEQUENTIAL, OR SPECIAL DAMAGES RESULTING FROM ANY ERROR IN THE PERFORMANCE OF THE SERVICES, REGARDLESS OF WHETHER THE PERSON PROVIDING SUCH SERVICES, ITS AFFILIATES, OR OTHERS MAY BE WHOLLY, CONCURRENTLY, PARTIALLY, OR SOLELY NEGLIGENT OR OTHERWISE AT FAULT.

(c) Any Direct Compression Equipment Costs and Expenses that are incurred by any Exterran Entity in connection with providing the Services shall be allocated to the Partnership at the actual cost to the applicable Exterran Entity providing such Services.

(d) The General Partner shall be entitled to allocate to the Partnership any costs and expenses (other than Direct Compression Equipment Costs and Expenses) incurred by any Exterran Entity in connection with providing the Services on any reasonable basis determined by the General Partner. In the event that such Services are associated with Exterran’s operation of both of the businesses of the USCSB and the Partnership Group, including, without limitation, general and administrative functions, such reasonable basis may include, at the election of the General Partner, allocating a portion of such costs and expenses incurred during a particular period to the Partnership on a pro rata basis based on the Partnership Group’s Percentage Interest.

(e) Subject to Section 3.2, the Partnership Group hereby agrees to reimburse the Exterran Entities for all costs and expenses allocated to the Partnership Group in accordance with the manners set forth in Sections 3.1(c) and (d).

3.2 Limitations on Reimbursement.

(a) Notwithstanding Section 3.1, the amount that the Exterran Entities are entitled to receive from the Partnership Group pursuant to Section 3.1 for selling, general and administrative costs during any particular quarter commencing with the quarter ending September 30, 2007 during the Limit Period shall not exceed $4.75 million (the “SG&A Limit”); provided, that with respect to the quarter ending September 30, 2007, it means $2.12 million. The SG&A Limit shall be reduced by any cash selling, general and administrative costs incurred directly by the Partnership Group during the applicable period. In the event that during the Limit Period the Partnership Group makes any additional acquisitions of assets or businesses or the businesses or the business of the Partnership Group otherwise expands after the date hereof, then the Parties shall negotiate in good faith any appropriate increase in the SG&A Limit in order to account for any adjustments in the nature and extent of the selling, general and administrative services provided by the Exterran Entities to the Partnership Group, with any such increase in the SG&A Limit subject to the approval of the Conflicts Committee

(b) Notwithstanding Section 3.1, the amount that the Exterran Entities are entitled to receive from the Partnership Group pursuant to Section 3.1 for Cost of Sales during any particular quarter during the Limit Period shall not exceed $18.00 times the Average Horsepower of the Partnership Group during such quarter (the “Cost of Sales Limit”). The Cost of Sales Limit shall be reduced by any Cost of Sales incurred directly by the Partnership Group during the applicable period. In the event that during the Limit Period the Partnership Group makes any additional acquisitions of assets or businesses or the business of the Partnership Group otherwise expands after the date hereof, then the Parties shall negotiate in good faith any appropriate increase in the Cost of Sales Limit in order to account for any adjustments in the Cost of Sales of the Partnership Group (on a per horsepower basis) as a result of such acquisition or expansion, with any such increase in the Cost of Sales Limit subject to the approval of the Conflicts Committee.

ARTICLE IV
COMPRESSION EQUIPMENT TRANSFERS

4.1 Transfer Mechanics

(a) In the event that Exterran determines in good faith that there exists a need on the part of the CCSB or on the part of the Partnership Group to transfer Compression Equipment between the Exterran Entities, on the one hand, and the Partnership Group, on the other hand, to meet the compression services obligations of either of the CCSB or the Partnership Group, such Compression Equipment shall be so transferred (or, to the extent provided in Section 4.2, leased), at the election of Exterran, from a member of the Exterran Entities to a member of the Partnership Group, or from a member of the Partnership Group to a member of the Exterran Entities, as the case may be; provided, that all of the following conditions are satisfied with respect to such transfer or lease (each such transfer or lease for the purposes of this Article IV, unless set forth otherwise, a “transfer”) at the Effective Time (as defined below) of such transfer:

4.2 Settlement; Appraised Value

(a) Prior to the Effective Time of any transfer pursuant to Section 4.1, the Partnership Group and Exterran will determine the aggregate Appraised Value of the Compression Equipment to be so transferred.

(b) In consideration for such transfer, the Transferee, at its discretion (subject to the provisos of Sections 4.2(b)(ii) and (ii) and subject to Sections 4.2(b) and (c)), shall take any one or more of the following actions prior to or contemporaneously with the Effective Time of such transfer:

(i) Transfer Compression Equipment to the Transferor of equal or greater Appraised Value than the Appraised Value of the Compression Equipment to be transferred to the Transferee pursuant to Section 4.1 (provided, that if such Compression Equipment is of greater Appraised Value than the Appraised Value of the Compression Equipment to be transferred to the Transferee pursuant to Section 4.1, such excess Appraised Value shall be deemed to be a transfer of Compression Equipment with a value equal to such excess Appraised Value and Transferor shall be required to take one or more of the actions contemplated by this Section 4.2(b) in consideration for such excess Appraised Value) in accordance with this Article IV;

(ii) Execute and deliver a lease agreement substantially in the form of the Form Lease Agreement pursuant to which the Transferee agrees to lease from the Transferor the Compression Equipment to be transferred to the Transferee pursuant to Section 4.1, which lease agreement shall be counter-signed by the Transferor (provided, however, that the ability of the Transferee to execute and deliver such a lease may be limited in the sole discretion of Exterran, to the extent that an Exterran Entity is the Transferor, or in the sole discretion of the Conflicts Committee, to the extent that a member of the Partnership Group is the Transferor); or

(iii) Deliver to the Transferor cash (or an obligation to make payment in cash no later than the end of the fiscal quarter in which the transfer is effected) in the amount of the aggregate Appraised Value of the Compression Equipment to be transferred to the Transferee pursuant to Section 4.1 (provided, however, that the ability of the Transferee to make such a payment may be limited in the sole discretion of Exterran, to the extent that an Exterran Entity is the Transferor, or in the sole discretion of the Conflicts Committee, to the extent that a member of the Partnership Group is the Transferor).

(c) In the event that the Transferee cannot through the use of its commercially reasonable efforts provide adequate consideration to the Transferor for Compression Equipment to be transferred in any of the manners set forth in Section 4.2(b), then no such transfer pursuant to the terms of this Article IV shall occur.

(d) Notwithstanding Section 4.2(b), if the Transferor is a member of the Partnership Group, the Transferee shall not be entitled to take the actions contemplated by Section 4.2(b)(ii) if such action would cause the Partnership to be treated as an association taxable as a corporation or otherwise to be taxed as an entity for federal income tax purposes. In such event, if compliance by Exterran with Sections 4.2(i) or (iii) is not commercially practicable, the Partnership and Exterran shall negotiate in good faith to reach agreement on another manner in which to reimburse the Partnership for such Compression Equipment; provided, that the final terms of such reimbursement shall be approved by the Conflicts Committee.

4.3 Appraisal. Exterran shall, at its sole cost and expense, cause an Appraisal of all Compression Equipment then owned by the CCSB and the Partnership Group to be conducted and prepared (i) no later than the end of the fiscal quarter in which the second anniversary of the Closing Date occurs and (ii) no less frequently than every two years thereafter.

4.4 Like-Kind Exchange Treatment. Each Party agrees to cooperate to the extent reasonably necessary to allow the other, if the other so desires, to treat the transactions contemplated by Section 4.1(b) as a like-kind exchange under Section 1031 of the Code, and relevant Treasury regulations and/or under relevant state law provisions, if any. Any Party seeking such treatment acknowledges that it has consulted or will consult with independent tax counsel regarding the applicability and benefits/detriments of such treatment and in no way has relied upon any representations of the other party regarding the same.

4.5 Other Sales Permitted. Nothing otherwise set forth in this Article IV shall be deemed to preclude any of the Exterran Entities and any member of the Partnership Group from negotiating or consummating at any time the purchase and sale of newly fabricated Compression Equipment, existing Compression Equipment or all or any part of the USCSB; provided, however, that such negotiations or purchase and sale shall be conducted pursuant to the terms and procedures then mutually agreed upon by Exterran and the General Partner or the Conflicts Committee, as applicable.

4.6 Termination. Unless this Agreement has otherwise terminated pursuant to Section 8.4, this Article IV shall terminate on the third anniversary of the Effective Date.

Ad valorem taxes relating to the ownership of Compression Equipment transferred pursuant to Section 4.1 shall be prorated on a daily basis between the Exterran Entities and the Partnership Group with the Exterran Entities and the Partnership Group responsible for the prorated portion of such taxes for the period of their respective ownership of such transferred Compression Equipment. As between the Exterran Entities and the Partnership Group, the party that receives the ad valorem tax billing (the “Billed Party”) shall provide a copy of such billing to the other party together with a calculation of the prorated ad valorem taxes owed by each party. The party that did not receive the ad valorem tax billing shall pay its prorated portion of the ad valorem taxes to the Billed Party prior to the due date of such taxes and the Billed Party shall be responsible for the timely payment of the ad valorem taxes to the taxing authorities.

(iii) all federal, state and local income tax liabilities attributable to the operation of the Partnership Assets prior to the Closing Date, including any such income tax liabilities of Exterran that may result from the consummation of the formation transactions for the Partnership Entities;

provided, however, that in the case of clauses (i) and (ii) above, such indemnification obligations shall terminate on the third anniversary of the Closing Date; and that in the case of clause (iii) above, such indemnification obligations shall survive until sixty (60) days after the termination of any applicable statute of limitations.

(b) In addition to and not in limitation of the indemnification provided under Section 7.1(b) and the Partnership Agreement and except as otherwise set forth in any Exhibit hereto, the Partnership Group shall indemnify, defend and hold harmless Exterran and its Affiliates from and against any claims, losses and expenses (including, without limitation, court costs and reasonable attorney’s and expert’s fees) of any and every kind or character, known or unknown, fixed or contingent, suffered or incurred by Exterran

and its Affiliates by reason of or arising out of events and conditions associated with the operation of the Partnership Assets and occurring on or after the Closing Date unless such indemnification would not be permitted under the Partnership Agreement by reason of one of the provisos contained in Section 7.7(a) of the Partnership Agreement.

7.3 Limitations Regarding Indemnification. (a) The aggregate liability of Exterran under Section 7.1(a) shall not exceed $5.0 million.

(c) Notwithstanding anything herein to the contrary, in no event shall Exterran have any indemnification obligations under Section 7.1(a) for claims made as a result of additions to or modifications of Environmental Laws promulgated after the Closing Date.

7.4 Indemnification Procedures

(a) The Indemnified Party agrees that promptly after it becomes aware of facts giving rise to a claim for indemnification under this Article VII, it will provide notice thereof in writing to the Indemnifying Party, specifying the nature of and specific basis for such claim; provided, however, that the Indemnified Party shall not submit claims more frequently than once a calendar quarter (or twice in the case of the last calendar quarter prior to the expiration of the applicable indemnity coverage under this Agreement).

(b) The Indemnifying Party shall have the right to control all aspects of the defense of (and any counterclaims with respect to) any claims brought against the Indemnified Party that are covered by the indemnification under this Article VII, including, without limitation, the selection of counsel, determination of whether to appeal any decision of any court and the settling of any such matter or any issues relating thereto; provided, however, that no such settlement shall be entered into without the consent of the Indemnified Party (with the concurrence of the Conflicts Committee in the case of the Partnership Group) unless it includes a full release of the Indemnified Party from such matter or issues, as the case may be, and does not include the admission of fault, culpability or a failure to act, by or on behalf of such Indemnified Party.

(c) The Indemnified Party agrees to cooperate fully with the Indemnifying Party, with respect to all aspects of the defense of any claims covered by the indemnification under this Article VII, including, without limitation, the prompt furnishing to the Indemnifying Party of any correspondence or other notice relating thereto that the Indemnified Party may receive, permitting the name of the Indemnified Party to be utilized in connection with such defense, the making available to the Indemnifying Party of any files, records or other information of the Indemnified Party

that the Indemnifying Party considers relevant to such defense and the making available to the Indemnifying Party, at no cost to the Indemnifying Party, of any employees of the Indemnified Party; provided, however, that in connection therewith the Indemnifying Party agrees to use reasonable efforts to minimize the impact thereof on the operations of the Indemnified Party and further agrees to endeavor to maintain the confidentiality of all files, records and other information furnished by the Indemnified Party pursuant to this Section 7.4. In no event shall the obligation of the Indemnified Party to cooperate with the Indemnifying Party as set forth in the immediately preceding sentence be construed as imposing upon the Indemnified Party an obligation to hire and pay for counsel in connection with the defense of any claims covered by the indemnification set forth in this Article VII; provided, however, that the Indemnified Party may, at its own option, cost and expense, hire and pay for counsel in connection with any such defense. The Indemnifying Party agrees to keep any such counsel hired by the Indemnified Party informed as to the status of any such defense, but the Indemnifying Party shall have the right to retain sole control over such defense.

(d) In determining the amount of any loss, cost, damage or expense for which the Indemnified Party is entitled to indemnification under this Agreement, the gross amount of the indemnification will be reduced by (i) any insurance proceeds realized by the Indemnified Party and (ii) all amounts recovered by the Indemnified Party under contractual indemnities from third Persons. The Partnership hereby agrees to use commercially reasonable efforts to realize any applicable insurance proceeds or amounts recoverable under such contractual indemnities.

(e) The date on which the Indemnifying Party receives notification of a claim for indemnification shall determine whether such claim is timely made.

If Lessee fails to pay any rental or other sum when due, Lessee also shall pay to Lessor interest thereon from the due date thereof to the date of payment at a rate equal to the lesser of 18% per annum or the maximum rate permitted by applicable law (“Applicable Rate”). All payments by Lessee hereunder shall be payable at the office of Lessor set forth below, or at such other place as Lessor from time to time may designate in writing. It is the intent of the parties that each Schedule shall have a Minimum Term that is no greater than a whole or fractional month less than 75% of the useful life of the Equipment subject to said Schedule. Notwithstanding anything in this Agreement to the contrary, a Schedule may be terminated prior to the expiration of its Minimum Term upon the purchase and sale or exchange between Lessor and Lessee of the Equipment subject to said Schedule in accordance with the term of the Omnibus Agreement.

3. Taxes. Lessee agrees to reimburse, promptly when due, all license fees and assessments and all sales, use, property, excise and other taxes or charges (including any interest and penalties), now or hereafter imposed by any governmental body or agency upon the Equipment or the purchase, ownership, possession, leasing, operation, use, or disposition thereof hereunder, or the rentals or other payments hereunder (excluding taxes on or measured by the net income of Lessor) and prepare and file promptly with the appropriate offices any and all tax and other similar returns required to be filed with respect thereto (sending copies thereof to Lessor) or, if requested by Lessor, notify Lessor of such requirement and furnish Lessor with all information required by Lessor so that it may effect such filing.

4. Inspection and Acceptance. Within 48 hours after delivery of the Equipment to be leased to Lessee under each Schedule, Lessee shall inspect the Equipment. Unless within said 48 hour period Lessee notifies Lessor in writing to the contrary stating the details of any defects, Lessee shall be

Exhibit B-1

conclusively presumed to have accepted the Equipment in its then condition. If within said 48 hour period Lessee notifies Lessor in writing of the unacceptability of the Equipment, Lessor’s obligations to lease the Equipment shall cease forthwith. Upon acceptance of delivery, Lessee assumes the care, custody, supervision and control of the Equipment and of any and all persons or property in the vicinity of the Equipment during the time of delivery, operation and return. Lessee acknowledges that all Equipment rented hereunder and specified in the Schedule(s) is of the size, design and capacity selected for the operating conditions furnished to Lessor by Lessee and is suitable for Lessee’s purposes. Lessee acknowledges that that Lessor is not the manufacturer or supplier of the Equipment and any quotations or recommendations made by Lessor are based on information supplied by Lessee and the manufacturer or supplier of the Equipment.

5. Freight. Lessee agrees to bear all of the cost of connecting the Equipment and of disconnecting the Equipment prior to returning the Equipment to Lessor. Except as otherwise provided in the Schedule, all costs of transporting the Equipment from Lessor’s yard to Lessee’s Site described on the Schedule and of transporting the Equipment from such Site back to Lessor’s yard will be at the expense of Lessee.

6. Insurance. Lessee shall, at Lessee’s sole cost and expense, maintain insurance or Lessor-approved self-insurance in such amounts, against such risks (including, without limitation, all risk and public liability insurance with respect to the Equipment), with such carriers and in such form as shall be satisfactory to Lessor naming Lessee as an insured and Lessor as an additional insured. Lessee shall provide Lessor with evidence of such insurance. The policies for such insurance shall provide that Lessor receive thirty (30) days notice of any termination, cancellation or alteration of the terms of such insurance, shall provide that the coverage afforded to Lessor shall not be rescinded, impaired or invalidated by any act or neglect of lessee and shall provide for waiver of subrogation and contribution by Lessee and Lessee’s insured against Lessor and Lessor’s employees and agents.

7. Use / Lessee’s Responsibilities. Lessee agrees to use the Equipment in a careful and prudent manner with competent agents, employees or subcontractors only for the compression of gas in accordance with the specifications of the manufacturer of the Equipment. Lessee agrees to pay for damages to the Equipment resulting from free water, excessive condensate or foreign solids, or impurities contained in the gas stream. Lessee further agrees to pay for all damages to the Equipment resulting from abusive use, failure to maintain the Equipment in accordance with this agreement or from any negligence on the part of Lessee, its agents, employees or subcontractors.

In addition to any Lessee obligations contained elsewhere in this Agreement and within any Schedules hereto, Lessee agrees to and shall:

a. Provide Lessor with authorized ingress and egress to and from the site designated in the Schedule for installation of the Equipment (the “Site”). Should Lessor be denied access to the Site for any reason not reasonably within Lessor’s control, any time lost by Lessor shall be paid for by Lessee at the applicable rate. Recognizing that Lessee has superior knowledge of the Site and access routes to the Site, Lessee must advise Lessor of any conditions or obstructions which Lessor might encounter while en route to the Site. Lessee agrees to maintain the road and Site in such a condition that will allow free access and movement to and from the Site in an ordinarily equipped highway type vehicle. If because of an attribute of Lessee’s operations, Lessor is required to use any specialized transportation equipment, cranes or other services and supplies, Lessee shall furnish the same at its expense and without cost to Lessor;

b. Prepare a sound location at the Site adequate in size and capable of properly supporting the Equipment; and

Exhibit B-2

c. Immediately mitigate and repair any stoppage, malfunction or leaks of oil or coolant from the Equipment.

8. No Maintenance / Bare Rental. Lessee acknowledges that Lessor is providing the Equipment as a “bare rental” and, therefore, Lessor will have no maintenance or inspection obligations with respect to the Equipment.

9. Inspection. Lessor shall have the right at all reasonable times to enter upon the premises where the Equipment may be located for the purpose of inspecting it or observing its use.

10. Title; Personal Property; Encumbrances; Location. Lessee covenants that:

b. The Equipment will be installed and used at the location specified in the Schedule pertaining thereto and that it shall not be removed therefrom without the permission of Lessor;

c. That Lessee will not, except as expressly authorized in this Agreement, sell, secrete, mortgage, assign, transfer, lease, sublet, loan part with possession of, or encumber the Equipment or permit any liens or charges to become effective thereon or permit or attempt to do any of the acts aforesaid. Lessee agrees, at Lessee’s own expense, to take such action as may be necessary to remove any such encumbrance, lien or charge and to prevent any third party from acquiring any other interest in the Equipment (including, without limitation, by reason of such Equipment being deemed to be a fixture or a part of any realty); and

d. Lessee will not change or remove any insignia, serial number or lettering of the Equipment.

11. Licenses, Permits and Compliance. Lessee, at its sole expense, shall;

a. Comply with all applicable rules and regulations of any Federal, Provincial, State, County, City, local, municipal or regulatory agency (hereinafter referred to as “Governing Bodies”) relating to the construction or operation of the Equipment in the Location, or environmental requirements associated therewith (including but not limited to air emission, noise and environmental discharges); and

b. Obtain and maintain throughout the Minimum Term, or any extension thereof, any and all licenses and/or permit fees assessed as a result of this Agreement or against said Equipment. Lessee further agrees to defend, protect, indemnify and hold harmless Lessor from any and all liability associated with its failure to comply with the foregoing provision.

12. Waste Disposal. Lessee bears responsibility for disposal of liquids, solid, and hazardous waste discharged by the Equipment at the location in accordance with federal, state and local environmental rules and regulations.

b. Lessee shall dissolve, or become insolvent (however evidenced) or bankrupt, commit any act of bankruptcy, make an assignment for the benefit of creditors, suspend the transaction of its usual

Exhibit B-3

business or consent to the appointment of a trustee or receiver, or a trustee or a receiver shall be appointed for Lessee or for a substantial part of its property, or bankruptcy, reorganization, insolvency, or similar proceedings shall be instituted by or against Lessee; or

c. an order, judgment, or decree shall be entered against Lessee by a court of competent jurisdiction and such order, judgment or decree shall continue unpaid or unsatisfied and in effect for any period of sixty (60) consecutive days without a stay of execution, or any execution or writ or process shall be issues in connection with any action or proceeding against Lessee or its property whereby the Equipment or any substantial part of Lessee’s property may be taken or restrained; or

d. any indebtedness of Lessee for borrowed money shall become due and payable by acceleration of maturity thereof;

e. Lessor shall in good faith believe that the prospect of payment or performance by Lessee is impaired,

then and in any such event, Lessor may, by written notice to Lessee:

(1) Immediately terminate this Agreement as to any or all Schedules, at its option, and Lessee’s rights thereunder; and/or

(2) Declare immediately due, and payable all rental installments and other sums hereunder forthwith due and payable whereupon the same shall forthwith become due and payable as liquidated damages and not as a penalty; and/or

(3) Proceed by appropriate court action or actions either at law or in equity, to enforce performance by Lessee of the applicable covenants of this Agreement or to recover damages for the breach thereof; and/or

(4) Without necessity of process or other legal action, enter onto the premises of Lessee or such other premises as the Equipment may then be located and stop the operation of the Equipment and/or take possession of the Equipment, disconnecting and separating the Equipment from any other property and using all force necessary or permitted by applicable law, without Lessor incurring any liability to Lessee or any other person arising out of the taking of any such action. Lessee agrees to and shall indemnify and hold harmless Lessor from any and all claims, losses, damages, causes of action, suits and liabilities of any kind arising in favor of Lessee, or any interest owner that Lessee represents or serves as operator and arising out of or in connection with the stopping of the operation of the Equipment and/or the removal of the Equipment as aforesaid, whether same result from the forfeiture of any oil, gas or mineral lease, damage to a producing reservoir or lease operations, lost production or other event or condition. In addition, Lessee shall continue to be liable for all other indemnities under this Agreement and for all legal fees and other costs and expenses resulting from the foregoing defaults or the exercise of Lessor’s remedies. Lessor shall be entitled to take or retain, by way of offset against any or all amounts due and owing under this Agreement, any assets, tangible or intangible, of Lessee which may then be in the possession of Lessor, its correspondents or agents, wheresoever situated.

14. Holding Over. Unless a party gives the other party thirty (30) days advance written notice of termination prior to the expiration of the Minimum Term specified in a Schedule, that Schedule will continue to bind the parties on a month-to-month basis as to the Equipment, subject thereafter to termination by either party with thirty (30) days advance written notice.. Notwithstanding the foregoing, after the expiration of the Minimum Term, Lessor may modify the rental fees and other charges assessed under this Agreement.

Exhibit B-4

15. Indemnity of Lessor.

a. Lessee is responsible and liable for loss of or damage to Equipment arising between the time of delivery and redelivery of the Equipment and Lessee shall protect, defend, indemnify and hold Lessor harmless from and against any such loss or damage, however arising, including but not limited to, improper operation, improper maintenance (unless Lessor performs maintenance), negligent acts of Lessee, compression of dirty or wet gas, fire, freezing, theft, windstorm, hailstorm, flood, riot, insurrection or explosion, except to the extent such loss or damage arises directly as a result of the negligence of Lessor.

b. Lessee shall protect, defend, indemnify and hold Lessor harmless from and against any loss, damage, liability, suit, expense, cost or claim, however occurring as the result of loss of or damage to property (other than the Equipment), arising between the time of delivery and redelivery of the Equipment, whether such property is owned by Lessee or third party, and for injury to or death of persons, whether Lessee or its employees or third parties.

16. Savings Clause. The parties agree that the indemnities in this Agreement are limited to the extent necessary to comply with applicable state or federal law and that this Agreement shall be deemed to be amended to comply with those laws to the extent their requirements are at variance with any indemnification provisions set forth in this Agreement.

17. Limitation of Liability. In no event shall Lessor, its agents and employees (for purposes of this Paragraph 17, such persons shall collectively be referred to as “Lessor”) be liable to Lessee, for any general, compensatory, special indirect, incidental or consequential damages related to or in connection with the use and operation of the Equipment and/or the performance of this Agreement, including but not limited to any injury, loss or damage to any property, any loss of profits or business opportunity, and any loss of use of the Equipment, irrespective of the reason or cause of such damages, whether any of such damages occur during or after the period of this Agreement, or that the claim for such damages is based on warranty, contract, tort or other theory of any nature whatsoever.

18. Assignment By Lessor. Lessor may assign its rights and delegate its duties under this Agreement. Lessor covenants to Lessee that Lessor is empowered to execute this Agreement. Conditioned upon Lessee’s performing the conditions hereof, Lessee shall peaceably and quietly hold, possess and use the Equipment during the Minimum Term and any extensions thereof without hindrance. If Lessor assigns the rents reserved herein or all or any of Lessor’s rights hereunder, such assignee’s rights shall be independent of any claim of Lessee against Lessor. Lessee on receiving notice of any such assignment shall abide thereby and make payment as may therein be directed. Following such assignment, the term “Lessor’ shall be deemed to include or refer to Lessor’s assignee, except such assignee’s rights shall be independent of any claim of Lessee against Lessor as hereinabove provided.

19. Assignment and Subleasing by Lessee. EXCEPT AS OTHERWISE EXPRESSLY PROVIDED IN THIS PARAGRAPH 19, LESSEE SHALL NOT, WITHOUT THE PRIOR CONSENT OF LESSOR, ASSIGN, TRANSFER OR ENCUMBER ITS RIGHTS, INTERESTS OR OBLIGATIONS UNDER THIS AGREEMENT. ANY ATTEMPTED ASSIGNMENT, TRANSFER OR ENCUMBRANCE BY LESSEE OF ITS RIGHTS, INTERESTS OR OBLIGATIONS UNDER THIS AGREEMENT SHALL BE NULL AND VOID. So long as no material event of default shall have occurred and be continuing, Lessee may, without the consent of Lessor, sublease one or more of the Equipment to any third party (each third part a “User” and each such lease a “User Lease”), provided that all of the following requirements shall be satisfied with respect to each such User Lease entered into pursuant to this Paragraph 19:

Exhibit B-5

a. the Equipment is and will remain physically located within the United States;

b. such User Lease shall be in writing, shall identify the Equipment by unit number, engine, frame and number of cylinders and shall expressly prohibit any further sublease or transfer by User of any rights or interests in the Equipment without Lessee’s permission;

c. such User Lease shall prohibit the User from making any alterations or modifications to the Compressors that would violate the provisions of Paragraph 23 of this Agreement; and

d. such User Lease shall require the User (and/or Lessee) (i) to maintain the Equipment in accordance with Paragraph 7 and the relevant Schedule and (ii) to engage in activities with the Equipment in a manner consistent with the Equipment’s intended purpose and in accordance with the Equipment’s specifications.

No such subleasing by Lessee will reduce or affect any of the obligations of Lessee hereunder or the rights of Lessor under this Agreement, and all of the obligations of Lessee hereunder shall be and remain primary and shall continue in full force and effect as the obligations of a principal and not of a guarantor or surety.

20. No Lessor Equipment Warranties. LESSOR LEASES THE EQUIPMENT TO LESSEE AS-IS AND EXPRESSLY DISCLAIMS AND MAKES NO WARRANTIES, EXPRESS OR IMPLIED, AS TO THE CONDITION, DESIGN, QUALITY, CAPACITY, MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE OF, OR ANY OTHER MATTER, CONCERNING THE EQUIPMENT. LESSEE HEREBY WAIVES ANY CLAIM (INCLUDING ANY CLAIM BASED ON STRICT OR ABSOLUTE LIABILITY IN TORT) IT MAY HAVE AGAINST LESSOR FOR ANY LOSS, DAMAGE (INCLUDING INCIDENTAL OR CONSEQUENTIAL DAMAGE) OR EXPENSES CAUSED BY OR RELATING TO THE EQUIPMENT.

21. Enforceability. If any part hereof is contrary to, prohibited by or deemed invalid under applicable laws or regulations of any jurisdiction, such provision shall be inapplicable and deemed omitted but shall not invalidate the remaining provisions hereof.

22. No Conditional Sale. It is the intention of the parties hereto to hereby create a lease on the Equipment described herein, and not a conditional sale. To provide solely for the eventuality that a court might hold this to be a conditional sale, Lessor hereby retains a purchase money security interest to secure payment of the sales price of the Equipment as determined by such court, and Lessee grants to Lessor all rights given to a secured party under the Uniform Commercial Code in addition to Lessor’s other rights hereunder. It is the intention of the parties that the Equipment shall be deemed personal property and that it not be deemed a fixture, even though it may be attached in some manner to realty.
