(a) As remuneration for the provision by EXCO to the Partnership Group of the Services, the Partnership shall on a monthly basis (i) pay EXCO an administrative services fee of $1,600,000 plus any applicable sales or use taxes, which amount represents EXCO's good-faith estimate of the actual time to be spent by its personnel performing the Services, plus related expenses (the "Administrative Services Fee") and (ii) reimburse EXCO for all third-party expenses that EXCO incurs on behalf of the Partnership Group, excluding any expenses that are directly chargeable to ▇▇▇▇▇ under the applicable joint operating agreements and the Master Operating Agreement (the "Expense Reimbursements", together with the Administrative Services Fee, the "Payment Amount"). For the avoidance of doubt, EXCO will pay all expenses that are directly chargeable to ▇▇▇▇▇ under their respective joint operating agreements and the Master Operating Agreement and the Partnership will reimburse EXCO for such expenses pursuant to the provisions of the Master Operating Agreement.

(b) The Administrative Services Fee paid EXCO pursuant to Section 4.1 of this Agreement shall be revised in the following circumstances:

(i) If the Partnership or any other member of the Partnership Group acquires additional assets or disposes of existing assets (including any acquisition or disposition of the equity of any entity), then EXCO or the Partnership may propose a revised Administrative Services Fee that covers the provision of Services following such acquisition or disposition. With respect to any revised Administrative Services Fee proposed by EXCO, if the General Partner, on behalf of the Partnership Group and with the concurrence of the Conflicts Committee, agrees to such revised Administrative Services Fee, then the new estimate of the Administrative Services Fee shall become part of this Agreement and replace the existing Administrative Services Fee. With respect to any revised Administrative Services Fee proposed by the Partnership (with the concurrence of the Conflicts Committee), if EXCO agrees to such revised Administrative Services Fee, then the new estimate of the Administrative Services Fee shall become part of this Agreement and replace the existing Administrative Services Fee. The Administrative Services Fee will remain in effect until such time as a new Administrative Services Fee is approved in accordance with the provisions of this Section 4.1(b) and EXCO shall continue to provide Services pursuant to the terms set forth herein.

(ii) EXCO shall review the Administrative Services Fee on an annual basis and propose a new Administrative Services Fee to the extent necessary to reflect any changes in the scope of Services, changes in personnel who are performing the Services, changes in the cost of such Services, including changes in compensation of such personnel, and changes in EXCO's good faith estimate of the time such personnel will spend performing Services on behalf of the Partnership Group. If approved by the General Partner and with the concurrence of the Conflicts Committee, then the new Administrative Services Fees shall become part of this Agreement and replace the existing Administrative Services Fee until such time as a new Administrative Services Fee is approved in accordance with the provisions of this Section 4.1(b) and EXCO shall continue to provide Services pursuant to the terms set forth herein.

(c) If EXCO and the Conflicts Committee are unable to agree on the amount of any revised Administrative Services Fee proposed pursuant to Section 4.1(b), EXCO and the Partnership will engage a mutually agreed upon independent registered public accounting firm to determine the Administrative Services Fee based on its estimate of the fair value of the Services provided to the Partnership Group by EXCO. Such independent registered public accounting firm will determine the revised Administrative Services Fee within 30 days of its engagement and furnish the Partnership and EXCO its determination, which shall be binding on all Parties. The fees of the independent registered public accounting firm will be split equally between EXCO and the Partnership.

Section 4.2 Payment of Payment Amount.

EXCO shall invoice the Partnership on or before the 20th day of each month for the estimated Payment Amount for the next succeeding month, plus or minus any adjustment necessary to correct prior estimated ▇▇▇▇▇▇▇▇ to actual ▇▇▇▇▇▇▇▇. Subject to Section 4.3, all invoices shall be due and payable, in immediately available funds, on the last day of the month to which the invoice relates. Upon the request of the Partnership, EXCO shall furnish a reasonable detail of the Services provided and charges assessed during any month.

Section 4.3 Disputed Charges.

THE PARTNERSHIP MAY, WITHIN 90 DAYS AFTER RECEIPT OF A CHARGE FROM EXCO, TAKE WRITTEN EXCEPTION TO SUCH CHARGE, ON THE GROUND THAT THE SAME WAS NOT A REASONABLE COST INCURRED BY EXCO OR ITS AFFILIATES IN CONNECTION WITH THE SERVICES. THE PARTNERSHIP SHALL NEVERTHELESS PAY EXCO IN FULL WHEN DUE THE FULL PAYMENT AMOUNT OWED TO EXCO. 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 REASONABLE COST INCURRED BY EXCO 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 EXCO 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 EXCO.

Section 4.4 Set Off.

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

Section 4.5 EXCO Employees.

The obligations of the Partnership under Sections 4.1 and 4.2, to the extent they relate to Services provided by employees of EXCO or its Affiliates, shall be limited to the Administrative Services Fee, and the Partnership shall not be obligated to pay directly to EXCO's or its Affiliates' employees any compensation, salaries, wages, bonuses, benefits, social security taxes, workers' compensation insurance, retirement and insurance benefits, training or other expenses; provided, however, that the Partnership may, at its option, compensate such employees under any long-term incentive plan of the Partnership for the provision of Services hereunder; and provided further, however, that if EXCO fails to pay any employee providing Services hereunder within 30 days of the date such employee's payment is due:

(a) The Partnership may (i) pay such employee directly or (ii) employ such employee directly; and

(b) EXCO shall reimburse the Partnership for the portion of the Administrative Services Fee representing employee compensation that the Partnership paid to EXCO with respect to such employee but that EXCO did not pay to such employee.

Section 4.6 Additional Review and Approvals.

EXCO acknowledges that all Expense Reimbursements assessed by EXCO and included in the Payment Amount must be approved by the persons authorized to approve such charges pursuant to the Partnership's governance processes. Additionally, EXCO acknowledges that the Conflicts Committee may direct the General Partner to modify the scope of Services pursuant to Section 2.3 or to revise the Administrative Services Fee pursuant to Section 4.1(b). In addition to the information EXCO is obligated to maintain and provide pursuant to Article III, EXCO shall provide such other information as reasonably necessary to determine the accuracy of any estimate relating to the Payment Amount hereunder.

ARTICLE V

FORCE MAJEURE

Section 5.1 Force Majeure.

If any party is rendered unable, wholly or in part, by force majeure to carry out its obligations under this Agreement, other than the obligation to indemnify or make money payments or furnish security, that party shall give to all other parties prompt written notice of the force majeure with reasonably full particulars concerning it; thereupon, the obligations of the party giving notice, so far as they are affected by the force majeure, shall be suspended during, but no longer than, the continuance of the force majeure. The term "force majeure", as here employed, shall mean an act of God, strike, lockout, or other industrial disturbance, act of the public enemy, war, blockade, public riot, lightning, fire, storm, flood or other act of nature, explosion, governmental action, governmental delay, restraint or inaction, unavailability of equipment, and any other cause, whether of the kind specifically enumerated above or otherwise, which is not reasonably within the control of the party claiming suspension. The affected party shall use all reasonable diligence to remove the force majeure situation as quickly as practicable. The requirement that any force majeure shall be remedied with all reasonable dispatch shall not require the settlement of strikes, lockouts, or other labor difficulty by the party involved, contrary to its wishes; how all such difficulties shall be handled shall be entirely within the discretion of the party concerned; provided, however, that in the event of a strike, lockout or other labor dispute involving EXCO, EXCO shall use reasonable efforts to continue to perform all obligations hereunder by utilizing its management personnel and that of its Affiliates.
