(a) The Indemnified Party agrees that promptly after it becomes aware of facts giving rise to a claim for indemnification under this Article IV, it will provide notice thereof in writing to the Indemnifying Party, specifying the nature of and specific basis for such claim.

(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 IV, including 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 (which consent shall not be unreasonably withheld, conditioned or delayed) 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 IV, including 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 4.6.

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, net of any related incremental insurance premiums that become due and payable by the Indemnified Party as a result of the associated claim, (ii) the amount of tax benefits received by the Indemnified Party with respect to such loss, cost, damage or expense and (iii) all amounts recovered by the Indemnified Party under contractual indemnities from third Persons.

ARTICLE V
RIGHT OF FIRST OFFER

5.1 EXCO Right of First Offer. For as long as the MLP remains an Affiliate of EXCO, and subject to the applicable provisions of the OLP Credit Agreement, if any Partnership Group Member (the "Partnership Disposing Party") desires to Transfer any EXCO Subject Assets, the Partnership Disposing Party shall provide the EXCO Group a right of first offer to acquire such EXCO Subject Assets pursuant to the procedures set forth below.

(a) The Partnership Disposing Party, with the approval of the Conflicts Committee, shall deliver a written offer (the "Partnership Disposing Party Offer") to EXCO, on behalf of the EXCO Group, which Partnership Disposing Party Offer shall describe the EXCO Subject Assets, the purchase price (payable in cash) at which it wishes to sell the EXCO Subject Assets and the proposed terms of sale. The Partnership Disposing Party Offer shall constitute a binding offer to sell the EXCO Subject Assets to the EXCO Group on the terms set forth therein.

(b) EXCO, on behalf of the EXCO Group, shall have a period of 30 days (the "EXCO Negotiation Period") from the date of the Partnership Disposing Party Offer to accept the Partnership Disposing Party Offer or negotiate alternative terms of sale acceptable to EXCO, on behalf of the EXCO Group, and the Partnership Disposing Party, with the approval of the Conflicts Committee.

(c) If the Partnership Disposing Party, with the approval of the Conflicts Committee, and EXCO, on behalf of the EXCO Group, agree upon the terms of sale for the EXCO Subject Assets prior to the expiration of the EXCO Negotiation Period, such Parties shall enter into definitive documentation to effect such transfer, which shall be closed within 30 days after the end of the EXCO Negotiation Period or such longer period as may be reasonably necessary to complete a stockholder vote by EXCO (if required) or a financing (if required) or to obtain any required consents.

(d) If, at the end of the EXCO Negotiation Period, the Partnership Disposing Party, with the approval of the Conflicts Committee, and EXCO, on behalf of the EXCO Group, each acting in good faith, have not agreed upon the terms of sale for the EXCO Subject Assets, or if the Transfer is not timely completed pursuant to Section 5.1(c), the Partnership Disposing Party may thereafter (i) Transfer the EXCO Subject Assets (subject to any changes in form or condition, financial or otherwise, which in the opinion of the Partnership Disposing Party, acting in good faith, are not material taken as a whole) to a bona fide third party dealing at arm's length with the Partnership Disposing Party (a "Partnership Third Party Transferee") at a price and on terms and conditions that, taken as a whole, in the reasonable opinion of the Partnership Disposing Party are not more favorable to the Partnership Third Party Transferee than those contained in the Partnership Disposing Party Offer taking into account any alternative terms proposed by EXCO or (ii) conduct a bona fide auction for the EXCO Subject Assets, seeking offers to be submitted to the Partnership Disposing Party by a specified date (the "Partnership Offer Date") from two or more Partnership Third Party Transferees and, if EXCO so desires, from EXCO, on behalf of the EXCO Group (each, a "Partnership Offer"), for consideration by the Partnership Disposing Party.

(e) If the Partnership Disposing Party conducts an auction pursuant to Section 5.1(d), the Partnership Disposing Party may accept the Partnership Offer that the Partnership Disposing Party, acting in good faith, determines is the best Partnership Offer. If EXCO does not submit a Partnership Offer on behalf of the EXCO Group or its Partnership Offer is not accepted by the Partnership Disposing Party, the EXCO Group thereafter waives all rights to the purchase of the EXCO Subject Assets, provided that the Partnership Disposing Party and the Partnership Third Party Transferee consummate the Transfer of the EXCO Subject Assets within 90 days from the expiration of the EXCO Negotiation Period.

(f) If the Partnership Disposing Party and the Partnership Third Party Transferee fail to consummate the Transfer of the EXCO Subject Assets within 90 days from the expiration of the EXCO Negotiation Period, the EXCO Group's rights under this Article V with respect to the EXCO Subject Assets shall again become effective, and the Partnership Disposing Party shall not thereafter Transfer any of the EXCO Subject Assets without first offering such assets to the EXCO Group in the manner provided in this Section 5.1.

(g) Upon any Transfer to a Third-Party Transferee, subject to paragraph (d) above, the Partnership Disposing Party shall deliver to EXCO, on behalf of the EXCO Group, a copy of the documents evidencing such Transfer.

ARTICLE VIII
POWERS OF ATTORNEY

8.1 Contributing Parties. Each of the Parties that is a transferor with respect to any Pre-Closing Assignment or any of the Closing Assignments and Assumptions (each, a "Contributing Party") hereby constitutes and appoints the Party that is the transferee in the relevant Pre-Closing Assignment or Closing Assignment and Assumption and its successors and assigns (the "Receiving Party"), its true and lawful attorney-in-fact with full power of substitution for it and in its name, place and stead or otherwise on behalf of the applicable Contributing Party and its successors and assigns, and for the benefit of the applicable Receiving Party and its successors and assigns, to demand and receive from time to time the applicable Assets contributed and to execute in the name of the applicable Contributing Party and its successors and assigns instruments of conveyance, instruments of further assurance and to give receipts and releases in respect of the same, and from time to time to institute and prosecute in the name of the applicable Contributing Party for the benefit of the applicable Receiving Party as may be appropriate, any and all proceedings at law, in equity or otherwise which the applicable Receiving Party and its successors and assigns, may deem proper in order to (A) collect, assert or enforce any claims, rights or titles of any kind in and to the applicable Assets, (B) defend and compromise any and all actions, suits or proceedings in respect of any of the applicable Assets and (C) do any and all such acts and things in furtherance of this Agreement as the applicable Receiving Party or its successors or assigns shall deem advisable.

ARTICLE IX
MISCELLANEOUS

9.1 Order of Completion of Transactions. The transactions provided for in Article II (except as otherwise noted) of this Agreement shall be completed or be deemed to have been completed, as the case may be, at the Effective Time in the following order (the completion of each such transaction being conditioned on the concurrent completion of the other transactions).

(a) First, the transactions provided for in Article II shall be completed in the order set forth therein;

(b) Second, the transactions provided for in Section 3.1 shall be completed contemporaneously with the transactions provided for in Section 2.6;

(c) Third, the transactions provided for in Section 3.2 shall be completed contemporaneously with the transactions provided for in Section 2.7;

(d) Fourth, the transactions provided for in Section 3.3 shall be completed contemporaneously with the transactions provided for in Section 2.8; and

(e) Fifth, the transactions provided for in Section 3.4, Section 3.5, Section 3.6 and Section 3.7 shall be completed contemporaneously with the transactions provided for in Section 2.11.

9.2 Consents; Restriction on Assignment. If there are prohibitions against or conditions to the contribution and conveyance of one or more of the Assets without the prior written consent of third parties, including, without limitation, Governmental Authorities (other than consents of a ministerial nature which are normally granted in the ordinary course of business), which if not satisfied would result in a breach of such prohibitions or conditions or would give an outside party the right to terminate rights of the Party to whom the applicable Assets were intended to be conveyed (the "Beneficial Owner") with respect to such portion of the Assets (herein called a "Restriction"), then any provision contained in this Agreement to the contrary notwithstanding, the transfer of title to or

interest in each such portion of the Assets (herein called the "Restricted Asset") shall not become effective unless and until such Restriction is satisfied, waived or no longer applies. When and if such a Restriction is so satisfied, waived or no longer applies, to the extent permitted by applicable Law and any applicable contractual provisions, the assignment of the Restricted Asset subject thereto shall become effective automatically as of the Effective Time, without further action on the part of any Party. Each of the applicable Parties that were involved with the conveyance of a Restricted Asset agrees to use its commercially reasonable efforts to obtain on a timely basis satisfaction of any Restriction applicable to any Restricted Asset conveyed by or acquired by any of them. The description of any portion of the Assets as a "Restricted Asset" shall not be construed as an admission that any Restriction exists with respect to the transfer of such portion of the Assets. In the event that any Restricted Asset exists, the applicable Party agrees to continue to hold such Restricted Asset in trust for the exclusive benefit of the applicable Party to whom such Restricted Asset was intended to be conveyed and to otherwise use its commercially reasonable efforts to provide such other Party with the benefits thereof, and the party holding such Restricted Asset will enter into other agreements, or take such other action as it may deem necessary, in order to ensure that the applicable Party to whom such Restricted Asset was intended to be conveyed has the assets and concomitant rights necessary to enable the applicable Party to operate such Restricted Asset in all material respects as it was operated prior to the Effective Time.

9.3 Costs. OLP shall pay all sales, use and similar taxes arising out of the contributions, conveyances and deliveries to be made under the Specific Conveyances and hereunder, and shall pay all documentary, filing, recording, transfer, deed, and conveyance taxes and fees required in connection therewith. In addition, OLP shall be responsible for all costs, liabilities and expenses (including court costs and reasonable attorneys' fees) incurred in connection with the satisfaction or waiver of any Restriction pursuant to Section 9.2 to the extent that such Restriction was disclosed to OLP at or before the Effective Time.

9.4 Notices. All notices or other communications required or permitted under, or otherwise in connection with, this Agreement must be in writing and must be given by depositing same in the U.S. mail, addressed to the Person to be notified, postpaid and registered or certified with return receipt requested or by transmitting by national overnight courier or by delivering such notice in person or by facsimile to such Party. Notice given by mail, national overnight courier or personal delivery shall be effective upon actual receipt. Notice given by facsimile shall be effective upon confirmation of receipt when transmitted by facsimile if transmitted during the recipient's normal business hours or at the beginning of the recipient's next business day after receipt if not transmitted during the recipient's normal business hours.

The words "hereof," "herein" and "hereunder" and words of similar import, when used in this Agreement, shall refer to this Agreement as a whole, including without limitation, all Schedules attached hereto, and not to any particular provision of this Agreement. All references herein to Articles, Sections and Schedules shall, unless the context requires a different construction, be deemed to be references to the Articles, Sections and Schedules of this Agreement, respectively, and all such Schedules attached hereto are hereby incorporated herein and made a part hereof for all purposes. All personal pronouns used in this Agreement, whether used in the masculine, feminine or neuter gender, shall include all other genders, and the singular shall include the plural and vice versa. The use herein of the word "including" following any general statement, term or matter shall not be construed to limit such statement, term or matter to the specific items or matters set forth immediately following such word or to similar items or matters, whether or not non-limiting language (such as "without limitation," "but not limited to," or words of similar import) is used with reference thereto, but rather shall be deemed to refer to all other items or matters that could reasonably fall within the broadest possible scope of such general statement, term or matter.

9.6 Assignment; Successors and Assigns. No Party hereto may sell, assign, transfer or convey any of its rights, or delegate any of its obligations, under this Agreement to any person without the prior written consent of the other Parties hereto provided, that any Partnership Group Member may assign all of its right, title and interests under this Agreement to secure debt for borrowed money and other obligations, including guarantees of such debt.

9.8 Counterparts. This Agreement may be executed in any number of counterparts, all of which together shall constitute one agreement binding on the Parties.

9.9 Governing Law; Submission to Jurisdiction. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Texas applicable to contracts made and to be performed wholly within such state without giving effect to conflict of law principles thereof, except to the extent that it is mandatory that the law of some other jurisdiction, wherein the Assets are located, shall apply. The Parties hereby submit to the jurisdiction of the state and federal courts of the State of Texas sitting in Dallas County, Texas.

9.10 Severability. If any of the provisions of this Agreement are held by any court of competent jurisdiction to contravene, or to be invalid under, the laws of any political body having jurisdiction over the subject matter hereof, such contravention or invalidity shall not invalidate the entire Agreement. Instead, this Agreement shall be construed as if it did not contain the particular provision or provisions held to be invalid and an equitable adjustment shall be made and necessary provision added so as to give effect to the intention of the Parties as expressed in this Agreement at the time of execution of this Agreement.

9.11 Deed; ▇▇▇▇ of Sale; Assignment. To the extent required and permitted by applicable law, this Agreement shall also constitute a "deed," "▇▇▇▇ of sale" or "assignment" in respect of the Closing Assignments.

9.12 Amendment or Modification. This Agreement may be amended or modified from time to time only by the written agreement of all the Parties hereto; provided, however, that, if at the time of such amendment or modification the limited partner interests of MLP are listed or traded on an

"exchange," as defined in Section 4(a)(1) of the Securities Exchange Act of 1934, as amended, such amendment or modification must be approved by the Conflicts Committee unless the General Partner determines in good faith that such amendment or modification will not adversely affect the Limited Partners in any material respect.

9.13 Integration. This Agreement, the instruments referenced herein, the Administrative Services Agreement, the Master Operating Agreement and the Deep Rights Farmout Agreement, supersede all previous understandings or agreements among the Parties, whether oral or written, with respect to the subject matter hereof. This Agreement, such instruments, the Administrative Services Agreement, the Master Operating Agreement and the Deep Rights Farmout Agreement, contain the entire understanding of the Parties with respect to the subject matter hereof and thereof. No understanding, representation, promise or agreement, whether oral or written, is intended to be or shall be included in or form part of this Agreement unless it is contained in a written amendment hereto executed by the Parties after the date of this Agreement.

9.14 Waiver. No failure by any Party to insist upon the strict performance of any covenant, duty, agreement or condition of this Agreement or to exercise any right or remedy consequent upon a breach thereof shall constitute waiver of any such breach of any other covenant, duty, agreement or condition.

9.15 Laws and Regulations. Notwithstanding any provision of this Agreement to the contrary, no Party hereto 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.
