ARTICLE IV
PAYMENT AMOUNT

Section 4.1 Administrative Fee.

(a)

The Partnership shall on a quarterly basis reimburse Pioneer USA and its Affiliates for their costs in providing the Services (the “Administrative Fee”), pursuant to any methodology determined in accordance with this Section 4.1. Initially and until changed as provided in this Section 4.1, the Administrative Fee will be based on a methodology of determining the Partnership Group’s share, on a per BOE basis, of certain of the general and administrative costs incurred by Pioneer USA and its Affiliates (excluding the Partnership Group). Under this initial methodology, the per BOE cost for Services during any period will be determined by dividing (i) the aggregate United States general and administrative costs of Pioneer USA and its Affiliates (excluding the Partnership Group) during such period, excluding such costs directly attributable to Pioneer USA’s and its Affiliates’ Alaska operations, by (ii) the sum of (x) the United States production during such period of Pioneer USA and its Affiliates (which for the avoidance of doubt includes the production of the Partnership

			Group), excluding any production attributable to Pioneer USA’s and its Affiliates’ Alaska operations, plus (y) the volumes delivered under all VPPs during such period. The Administrative Fee will then be determined by multiplying the per BOE costs by the total production of the Partnership during such period. For 2007, it is estimated that the Administrative Fee for the Partnership Group will be $1.08 per BOE of the Partnership Group’s production. The Administrative Fee may be based on amounts estimated by Pioneer USA if actual amounts are not available as determined by Pioneer USA. The Administrative Fee for the quarter containing the Effective Date shall equal the Administrative Fee that would have been payable for the full quarter multiplied by a fraction the numerator of which is equal to the number of days from the Effective Date until the end of such quarter and the denominator of which is equal to the number of days in such quarter.

	(b)		From time to time, Pioneer USA may propose changes to the methodology of calculating the Administrative Fee. Any change in the methodology of calculation will take effect when the General Partner, on behalf of the Partnership Group, consents to such change. The consent of the General Partner will not be unreasonably withheld, delayed or conditioned, so long as the methodology proposed reasonably compensates Pioneer USA and its Affiliates for their costs in providing the Services.

	(c)		On an annual basis, commencing with fiscal year 2008, Pioneer USA will review the Administrative Fee charged during the previous twelve month period. The review of the previous twelve month period shall involve a comparison of the final general and administrative expense and production amounts to the amounts used to calculate the Administrative Fee for the previous twelve month period in order to determine if the Partnership was overcharged or undercharged. Any overcharged or undercharged amounts will be reflected as a decrease or increase, respectively, to the Administrative Fee for the then current fiscal quarter.

Section 4.2 Direct Costs. The Partnership shall reimburse Pioneer USA and its Affiliates for all third-party expenses that Pioneer USA and its Affiliates incur on behalf of the Partnership Group, if any (the “Direct Costs”).

Section 4.3 XXXXX Fee. Pioneer USA shall be entitled to retain any XXXXX overhead charges associated with drilling and operating xxxxx billed in accordance with operating agreements to the extent that it is the operator of such xxxxx. The Partnership will pay all expenses that are directly chargeable to xxxxx under operating agreements.

Section 4.4 Payment Terms.

(a)

Pioneer USA shall invoice the Partnership within twenty-five (25) days after the close of each quarter for the actual or estimated amount of the Administrative Fee, plus or minus any adjustments necessary to correct

			estimated xxxxxxxx to actual xxxxxxxx. Subject to Section 4.5, all invoices shall be due and payable, in immediately available funds within fifteen (15) days after receipt of each invoice. Upon the request of the Partnership, Pioneer USA shall furnish a reasonable detail of the calculation of the Administrative Fee during any quarter. Pioneer USA has the right to charge the Partnership interest on all past due invoices at the Default Rate.

	(b)		The Partnership shall reimburse Pioneer USA or its Affiliates within five (5) days after receipt of an invoice and related support, for Direct Costs incurred by Pioneer USA and its Affiliates. Pioneer USA has the right to charge the Partnership interest on all past due invoices at the Default Rate.

Section 4.5 Disputed Charges. THE PARTNERSHIP MAY, WITHIN 120 DAYS AFTER RECEIPT OF A CHARGE FROM PIONEER USA, TAKE WRITTEN EXCEPTION TO SUCH CHARGE, ON THE GROUND THAT THE CHARGE WAS NOT A CORRECT CALCULATION OF THE ADMINISTRATIVE FEE AND/OR A REASONABLE COST INCURRED BY PIONEER USA OR ITS AFFILIATES IN CONNECTION WITH THE SERVICES. THE PARTNERSHIP SHALL NEVERTHELESS PAY PIONEER USA IN FULL WHEN DUE THE FULL ADMINISTRATIVE FEE AND ANY DIRECT COSTS CHARGED TO PIONEER USA. SUCH PAYMENT SHALL NOT BE DEEMED A WAIVER OF THE RIGHT OF THE PARTNERSHIP TO RECOUP ANY CONTESTED PORTION OF ANY AMOUNT SO PAID. HOWEVER, IF THE AMOUNT AS TO WHICH SUCH WRITTEN EXCEPTION IS TAKEN, OR ANY PART THEREOF, IS ULTIMATELY DETERMINED NOT TO BE A CORRECT CALCULATION OF THE ADMINISTRATIVE FEE AND/OR A REASONABLE COST INCURRED BY PIONEER USA OR ITS AFFILIATES IN CONNECTION WITH ITS PROVIDING THE SERVICES HEREUNDER, SUCH AMOUNT OR PORTION THEREOF (AS THE CASE MAY BE) SHALL BE REFUNDED BY PIONEER USA TO THE PARTNERSHIP TOGETHER WITH INTEREST THEREON AT THE DEFAULT RATE DURING THE PERIOD FROM THE DATE OF PAYMENT BY THE PARTNERSHIP TO THE DATE OF REFUND BY PIONEER USA.

Section 4.6 Set Off. In the event that Pioneer USA owes the Partnership a sum certain in an uncontested amount under any other agreement, then any such amounts may be aggregated and the Partnership and Pioneer USA may discharge their obligations by netting those amounts against any amounts owed by the Partnership to Pioneer USA under this Agreement. If the Partnership or Pioneer USA owes the other party a greater aggregate amount, that Party may pay to the other Party the difference between the amounts owed.

Section 4.7 Pioneer USA’s Employees. The Partnership shall not be obligated to pay to Pioneer USA’s or its Affiliates’ employees directly any compensation, salaries, wages, bonuses, benefits, social security taxes, workers’ compensation insurance, retirement and insurance benefits, training and other such expenses; provided, however, that the Partnership or the General Partner or its Affiliates may, at its option, compensate such employees under one or more equity-based incentive compensation plans for the provision of Services hereunder and the Partnership will reimburse the General Partner or such Affiliate for the cost incurred for such compensation.

Section 4.8 Approval of Expenses. Pioneer USA acknowledges that the Audit Committee of the Board of Directors of the General Partner, or if there is no Audit Committee, the entire Board of Directors of the General Partner, may at any time review the Administrative Fee, any Direct Costs and the levels of Services and, as a result, may direct the Partnership to decrease the level of Services or to dispute a prior invoice pursuant to Section 4.5. In addition to the information Pioneer USA is obligated to provide pursuant to Section 4.4(a), Pioneer USA shall provide such other information as reasonably necessary to determine the veracity or appropriateness of any Administrative Fee or Direct Costs hereunder.

ARTICLE V
FORCE MAJEURE

Section 5.1 Force Majeure. A Party’s obligation under this Agreement shall be excused when and to the extent its performance of that obligation is prevented due to Force Majeure; provided, however, that a Party shall not be excused by Force Majeure from any obligation to pay money. The Party that is prevented from performing its obligation by reason of Force Majeure shall promptly notify the other Parties of that fact and shall exercise due diligence to end its inability to perform as promptly as practicable. Notwithstanding the foregoing, a Party is not required to settle any strike, lockout or other labor dispute in which it may be involved; provided, however, that, in the event of a strike, lockout or other labor dispute affecting Pioneer USA, Pioneer USA shall use reasonable efforts to continue to perform all obligations hereunder by utilizing its management personnel and that of its Affiliates.

ARTICLE VI

	(c)		Notwithstanding the foregoing, a merger shall not be deemed to be an assignment and a transfer of the rights and an assumption of the obligations under this Agreement in connection with the transfer of all or substantially all of the assets of a Party shall not be deemed an assignment of such rights or obligations of such Party to this Agreement.

ARTICLE VII

Section 10.3 Entire Agreement. This Agreement constitutes the entire agreement of the Parties relating to the matters contained herein, superseding all prior contracts or agreements, whether oral or written, relating to the matters contained herein.

Section 10.4 Further Action. In connection with this Agreement and all transactions contemplated by this Agreement, each Party agrees to execute and deliver such additional documents and instruments and to perform such additional acts as may be necessary or appropriate to effectuate, carry out and perform all of the terms, provisions and conditions of this Agreement and all such transactions.

Section 10.5 Binding Effect. This Agreement shall be binding upon and inure to the benefit of the Parties hereto and their heirs, executors, administrators, successors, legal representatives and permitted assigns.

Section 10.6 Creditors. None of the provisions of this Agreement shall be for the benefit of, or shall be enforceable by, any creditor of the Partnership.

Section 10.7 Effect of Waiver or Consent. No waiver or consent, express or implied, by any Party to or of any breach or default by any Person in the performance by such Person of its obligations hereunder shall be deemed or construed to be a consent or waiver to or of any other breach or default in the performance by such Person of the same or any other obligations of such Person hereunder. Failure on the part of a Party to complain of any act of any Person or to declare any Person in default, irrespective of how long such failure continues, shall not constitute a waiver by such Party of its rights hereunder until the applicable statute of limitations period has run.

Section 10.8 Counterparts. This Agreement may be executed in counterparts, all of which together shall constitute an agreement binding on all the Parties hereto, notwithstanding that all such Parties are not signatories to the original or the same counterpart. Each Party shall become bound by this Agreement immediately upon affixing its signature hereto.

Section 10.9 Invalidity of Provisions. If any provision of this Agreement or the application thereof to any Person or circumstance shall be held invalid or unenforceable to any extent, the remainder of this Agreement and the application of such provision to other Persons

or circumstances shall not be affected thereby and shall be enforced to the greatest extent permitted by law.

Section 10.10 Amendment or Restatement. This Agreement may be amended or restated only by a written instrument executed by each of the Parties; provided, however, that after the completion of the Partnership’s initial public offering of common units representing limited partner interests, the Partnership may not, without the prior approval of the conflicts committee of the board of directors of the General Partner or, if there is no such committee, the independent members of such board of directors, agree to any amendment or modification of this Agreement that the General Partner determines will adversely affect the holders of such Common Units. The Parties hereto agree that, for purposes of this Section 10.10, any material change in the nature, quantity or duration of the Services to be provided under this Agreement shall constitute a modification of this Agreement.

Section 10.11 Withholding or Granting of Consent. Each Party may, with respect to any consent or approval that it is entitled to grant pursuant to this Agreement, grant or withhold such consent or approval in its sole and uncontrolled discretion, with or without cause, and subject to such conditions as it shall deem appropriate.

Section 10.12 Directly or Indirectly. Where any provision of this Agreement refers to action to be taken by any Party, or which such Party is prohibited from taking, such provision shall be applicable whether such action is taken directly or indirectly by such Party, including actions taken by or on behalf of any Affiliate of such Party.

Section 10.13 Laws and Regulations. Notwithstanding any provision of this Agreement to the contrary, no Party shall be required to take any act, or fail to take any act, under this Agreement if the effect thereof would be to cause such Party to be in violation of any applicable law, statute, rule or regulation.

Section 10.14 Negation of Rights of Limited Partners, Assignees and Third Parties. Except as set forth in Article IX, the provisions of this Agreement are enforceable solely by the Parties, and no limited partner, member, or assignee of the Partnership or other Person shall have the right, separate and apart from the Partnership, to enforce any provision of this Agreement or to compel any Party to comply with the terms of this Agreement.

Section 10.15 No Recourse Against Officers or Directors. For the avoidance of doubt, the provisions of this Agreement shall not give rise to any right of recourse against any officer or director of any member of the Partnership Group or any Pioneer Indemnified Party.

Section 10.16 Arbitration. Any claim, counterclaim, demand, cause of action, dispute, or any other controversy arising out of or relating in any way to this Agreement or to the subject matter of this Agreement or to any relationship created thereby (each a “Dispute”) shall be resolved by binding arbitration. A Dispute must be resolved through arbitration regardless of whether the Dispute involves claims that this Agreement is unlawful, unenforceable, void or voidable or involves claims sounding in tort, contract, statute or common law. This Section 10.16 shall be binding on and shall inure to the benefit of the Parties and their Affiliates, the Partnership Group and the Pioneer Indemnified Parties. The validity, construction and

interpretation of this agreement to arbitrate, and all other procedural aspects of the arbitration conducted pursuant hereto, shall be decided by the arbitral tribunal. Any arbitration under this Agreement shall be administered by the American Arbitration Association (“AAA”) and conducted in accordance with the Commercial Arbitration Rules (the “Rules”) of the AAA in existence at the time of the arbitration. In resolving any Dispute, the arbitral tribunal shall refer to the governing law as specified in Section 10.1 of this Agreement. The arbitral tribunal shall not be empowered to award exemplary, punitive, indirect, consequential, remote, speculative, treble, multiple or special damages, and the Parties and their Affiliates, the Partnership Group and the Pioneer Indemnified Parties waive any right they may have to recover such damages from one another. The arbitral tribunal shall not be empowered to decide any dispute ex aequo et xxxx or amiable compositeur. The seat (or legal place) and venue of the arbitration shall be in Dallas, Texas. The arbitration shall be conducted in the English language.

The Dispute shall be decided by a panel of three neutral arbitrators. The claimant or claimants shall nominate an arbitrator at the time of service of a request for arbitration. The respondent or respondents shall nominate an arbitrator at the time of service of the response to the request for arbitration. If the claimant(s) or respondent(s) fail to appoint an arbitrator, then that arbitrator shall be appointed in accordance with the Rules. The two appointed arbitrators shall together agree upon a third arbitrator to recommend to the AAA to chair the arbitration. If the two party-appointed arbitrators are unable to agree upon an arbitrator within 15 days of the respondent’s appointment of an arbitrator, then the chairman shall be chosen according to the Rules. Notwithstanding the foregoing, if two or more respondents have interests with regard to a Dispute that are not completely common, then all arbitrators shall be appointed in accordance with the Rules and not by nomination or appointment by the Parties. Any arbitration award may be enforced by the courts sitting in Dallas, Texas or any other court of competent subject matter jurisdiction (including any jurisdiction in which a Party holds or keeps assets). Any action to challenge, vacate or set aside the award in whole or in part must be brought in the courts sitting in Dallas, Texas. The Parties and their Affiliates, the Partnership Group and the Pioneer Indemnified Parties agree to waive any objections they may have to personal jurisdiction, venue or forum non-conveniens for any action brought to enforce the award in the courts sitting in Dallas, Texas or any other jurisdiction where a party against which enforcement of the award is sought holds or keeps assets.

IN WITNESS WHEREOF, the Parties have executed this Agreement on, and effective as of, the Effective Date.
