PAYMENT AMOUNT

     Section 4.1 Payment Amount.

     (a) The Partnership shall on a quarterly basis (i) pay Encore Operating a fixed fee of $1.75 per BOE of the Partnership Group’s total net oil and gas production for the then completed quarter (the “Administrative Fee”) and (ii) reimburse Encore Operating for all third-party expenses that Encore Operating incurs on behalf of the Partnership Group (collectively with the Administrative Fee, the “Payment Amount”). In addition to the Payment Amount, Encore Operating shall be entitled to retain any COPAS overhead charges associated with drilling and operating wells that would otherwise be paid by third

parties to the operator of a well. For the avoidance of doubt, the Partnership will pay all expenses that are directly chargeable to wells under their respective joint operating agreements.

     (b) The Administrative Fee shall increase in the following circumstances:

     (i) Beginning on the first day of April in each year beginning with April 1, 2008, the Administrative Fee shall increase by an amount equal to the product of the then-current Administrative Fee multiplied by COPAS Wage Index Adjustment for the current year.

     (ii) If the Partnership or any other member of the Partnership Group acquires additional assets, then Encore Operating may propose a revised Administrative Fee that covers the provision of Services for such additional assets. If the General Partner, on behalf of the Partnership Group and with the concurrence of the conflicts committee of the board of directors of the General Partner, agrees to such revised Administrative Fee, Encore Operating shall provide Services for the additional assets pursuant to the terms set forth herein.

     (iii) If the Partnership and Encore Operating otherwise agree to increase the Administrative Fee; provided, however, that any such increase shall be approved by the board of directors of the General Partner with the concurrence of the conflicts committee of such board.

     Section 4.2 Payment of Payment Amount. Encore Operating shall invoice the Partnership within 25 days after the close of each quarter for the estimated Payment Amount, plus or minus any adjustment necessary to correct prior estimated billings to actual billings. Subject to Section 4.3, all invoices shall be due and payable, in immediately available funds, within thirty days after receipt of each invoice. Upon the request of the Partnership, Encore Operating shall furnish a reasonable detail of the Services provided and charges assessed during any quarter.

     Section 4.3 Disputed Charges. THE PARTNERSHIP MAY, WITHIN 120 DAYS AFTER RECEIPT OF A CHARGE FROM ENCORE OPERATING, TAKE WRITTEN EXCEPTION TO SUCH CHARGE, ON THE GROUND THAT THE SAME WAS NOT A CORRECT CALCULATION OF THE ADMINISTRATIVE FEE AND/OR A REASONABLE COST INCURRED BY ENCORE OPERATING OR ITS AFFILIATES IN CONNECTION WITH THE SERVICES. THE PARTNERSHIP SHALL NEVERTHELESS PAY ENCORE OPERATING IN FULL WHEN DUE THE FULL PAYMENT AMOUNT OWED TO ENCORE OPERATING. 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 ENCORE OPERATING 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 ENCORE

OPERATING 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 ENCORE OPERATING.

     Section 4.4 Set Off. In the event that Encore Operating 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 Encore Operating may discharge their obligations by netting those amounts against any amounts owed by the Partnership to Encore Operating under this Agreement. If the Partnership or Encore Operating owes the other party a greater aggregate amount, that Party may pay to the other Party the difference between the amounts owed.

     Section 4.5 Encore Operating’s Employees. The obligations under Sections 4.1 and 4.2, to the extent they relate to Services provided by employees of Encore Operating or its Affiliates, shall be limited to payment to Encore Operating for expenses in connection with its or its Affiliates’ employees engaged in the provision of Services hereunder, and the Partnership shall not be obligated to pay to Encore Operating’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 may, at its option, compensate such employees under one or more equity-based incentive compensation plans for the provision of Services hereunder; and provided further, however, that if Encore Operating fails to pay any employee, with the exception of employee claims for amounts owed that Encore Operating disputes in good faith, within 30 days of the date such employee’s payment is due:

     (a) The Partnership may (i) pay such employee directly, (ii) employ such employee directly, (iii) notify Encore Operating and begin to pay all employees providing service to the Partnership directly, or (iv) notify Encore Operating that this Agreement is terminated and employ all employees directly; and

     (b) Encore Operating shall reimburse the Partnership, as the case may be, the amount the Partnership paid to Encore Operating for employee services that Encore Operating did not pay to any such employee.

     Section 4.6 Approval of Expenses. Encore Operating acknowledges that all charges for Services assessed by Encore Operating and included in the Payment Amount must be approved by the persons authorized to approve such Payment Amount pursuant to the Partnership’s governance and delegation-of-authority process. Additionally, Encore Operating 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 Payment Amounts 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 4.3. In addition to the information Encore Operating is obligated to provide pursuant to Section 4.2, Encore Operating shall provide such other information as reasonably necessary to determine the veracity or appropriateness of any Payment Amount hereunder.

     Section 4.7 Tax Reimbursement. The Partnership shall reimburse EAC for any additional state income, franchise or similar tax paid by EAC resulting from EAC’s inclusion of

one or more members of the Partnership Group with EAC in a combined state income, franchise or similar tax report. With respect to any such combined state income, franchise or other tax report, the amount of the Partnership’s reimbursement to EAC shall be equal to the tax that those Partnership Group members included with EAC on such tax report would have paid had such Partnership Group members not been included on such report. Any reimbursement payment required under this provision will be due within 45 days after EAC makes the tax payment giving rise to such reimbursement.

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 Encore Operating, Encore Operating shall use reasonable efforts to continue to perform all obligations hereunder by utilizing its management personnel and that of its Affiliates.

ASSIGNMENTS AND SUBCONTRACTS

     Section 6.1 Assignments.

     (a) Without the prior consent of Encore Operating, none of the Partnership or the other members or the Partnership Group may sell, assign, transfer or convey any of its rights, or delegate any of its obligations, under this Agreement to any Person.

Subject to the above, Encore Operating shall, to the extent practicable, engage employees who reside in or whose businesses are located in the local area or state where the Services are performed.
