Investor shall also on or before the Defect Claim Date use its good faith efforts to furnish EXCO Parent with written notice of any Title Defect or Title Benefit that is discovered by Investor or any of its Representatives while conducting Investor’s due diligence with respect to the Production Assets prior to the Defect Claim Date.

(b) Upon EXCO Parent’s delivery of a Remedy Notice to Investor prior to Closing, EXCO Parent shall have the right, but not the obligation, to attempt, at its sole cost, to cure or remove (or cause to be cured or removed) on or before the 90th day after the Closing Date (the “Cure Period”) any Title Defects for which EXCO Parent has received a Title Defect Notice from Investor prior to the Defect Claim Date. With respect to any Title Defect (i) for which EXCO Parent has provided a Remedy Notice to Investor prior to or on the Closing Date which is not cured by EXCO Parent prior to Closing or (ii) for which EXCO Parent disputes the existence of a Title Defect or disputes the Title Defect Amount with respect to a Title Defect where the Parties have agreed on the remedy set forth in Section 3.2(c)(i) with respect thereto (in each case, a “Disputed Title Defect”), then, subject to the Individual Title Defect Threshold and the Aggregate Defect Deductible, at or substantially concurrent with Closing, an Escrow Amount determined in accordance with Section V.a of Annex A, computed using the Reference Title Defect Amount applicable to such Title Defect, shall be deposited in accordance with Section V.a of Annex A into an escrow account with an escrow agent mutually agreeable to Investor and EXCO Parent (such escrow agent, the “Escrow Agent” and such account, the “Title Defect Escrow Account”), and the Transaction Items shall be adjusted accordingly in accordance with Section V.a of Annex A. If any Title Defect with respect to which EXCO Parent has provided a Remedy Notice to Investor, and with respect to which the Escrow Amount relating thereto has been deposited into the Title Defect Escrow Account is cured prior to the expiration of the Cure Period, then the Parties shall effect the actions required by Section V.b of Annex A in respect of such Title Defect. If any Title Defect with respect to which EXCO Parent has provided a Remedy Notice to Investor is not cured by EXCO Parent within the Cure Period, then, on or before the fifth day after the expiration of the Cure Period (the “Remedy Deadline”), or if later on or before the fifth day after the final determination of the applicable Title Defect Amount pursuant to Section 3.4, the Parties shall effect the actions required by Section V.c, Section V.d or Section V.e of Annex A, as applicable, with respect to such Title Defect. Notwithstanding the foregoing, any disputes with respect to (x) the proper and adequate cure for any such Title Defect, (y) any Title Defect Amount or (z) whether the alleged Title Defect constitutes a Title Defect, shall be finally and exclusively resolved in accordance with the provisions of Section 3.4, and the Parties shall effect the actions required by Section V of Annex A in accordance with the determination of the Title Arbitrator pursuant to Section 3.4. An election by EXCO Parent to attempt to cure a Title Defect shall be without prejudice to its rights under Section 3.4 and shall not constitute an admission against interest or a waiver of EXCO Parent’s right to dispute the existence, nature or value of, or cost to cure, the alleged Title Defect. Any Disputed Title Defects (including disputes with respect to whether any Disputed Title Defect has been cured) that have not been waived or otherwise resolved by EXCO Parent and Investor prior to the Remedy Deadline shall be exclusively and finally resolved in accordance with the provisions of Section 3.4.

(c) In the event that any Title Defect is not either waived by Investor or cured (as agreed by the Parties), in each case prior to the Closing, EXCO Parent and Investor shall mutually agree upon one of the following remedies (subject to the Individual Title Defect Threshold and the Aggregate Defect Deductible):

(i) make an adjustment to the Transaction Items pursuant to (x) Section II.a of Annex A if the Title Defect Amount applicable to such Title Defect is agreed by the Parties or (y) Section V.a of Annex A if the Title Defect Amount applicable to such Title Defect is disputed by the Parties;

(ii) have the applicable EXCO Party retain the entirety of the Title Defect Property (and any Assets solely related to such Title Defect Property) that is adversely affected by such Title Defect in which event the Transaction Items shall be adjusted pursuant to Section II.a of Annex A, based on the Allocated Value of such Title Defect Property and such Title Defect Property (and any Assets solely related to such Title Defect Property) shall no longer be included within the definition of Assets or Production Assets (or EXCO Parent Assets or EOC Assets, as applicable) for any purpose under this Agreement and such Title Defect Property (and any Assets solely related to such Asset) shall become an Excluded Asset hereunder and the Assumed Obligations shall not include liabilities or obligations relating to such Excluded Asset; or

(iii) have EXCO Parent indemnify MLP LLC, pursuant to a written indemnity agreement, in form and substance reasonably satisfactory to Investor, for any and all Damages arising out of or resulting from such Title Defect.

With respect to any Title Defect, if Investor and EXCO Parent cannot agree upon the remedy for such Title Defect under Section 3.2(c)(i), Section 3.2(c)(ii) or Section 3.2(c)(iii) above prior to the Closing, then Investor and EXCO Parent shall be deemed to have chosen the remedy under Section 3.2(c)(ii) with respect to such Title Defect.

(d) The Title Defect Amount resulting from a Title Defect shall be the amount by which the Allocated Value of the Title Defect Property adversely affected by such Title Defect is reduced as a result of the existence of such Title Defect and shall be determined in accordance with the following methodology, terms and conditions:

(i) if Investor and EXCO Parent agree on the Title Defect Amount, that amount shall be the Title Defect Amount;

(ii) if the Title Defect is a lien, encumbrance or other charge that is undisputed and liquidated in amount, then the Title Defect Amount shall be the amount necessary to be paid to remove the Title Defect from the applicable EXCO Party’s interest in the affected Title Defect Property;

(iii) if the Title Defect reflects a discrepancy (with a proportional decrease in the Working Interest for the affected Title Defect Property) between (A) the Net Revenue Interest for the affected Title Defect Property and (B) the Net Revenue Interest stated in Schedule 2.4 or Schedule 3.2 (as applicable), then the Title Defect Amount shall be the product of the Allocated Value of such Title Defect Property multiplied by a fraction, the numerator of which is the amount of the Net Revenue Interest decrease and the denominator of which is the Net Revenue Interest stated in Schedule 2.4 or Schedule 3.2 (as applicable);

(iv) if the Title Defect represents an obligation, encumbrance, burden or charge upon or other defect in title to the Title Defect Property of a type not described in subsections (ii) or (iii) above, the Title Defect Amount shall be determined by taking into account the Allocated Value of the Title Defect Property, the portion of the Title Defect Property adversely affected by the Title Defect, the legal effect of the Title Defect, the potential economic effect of the Title Defect over the life of the Title Defect Property, the reasonable cost and expense of curing or remediating, as applicable, such Title Defect, and such other factors as are necessary to make a proper evaluation;

(v) the Title Defect Amount with respect to a Title Defect shall be determined without duplication of any costs or losses included in any other Title Defect Amount hereunder, or for which Investor otherwise receives credit in the calculation of the adjustments to the Transaction Items pursuant to Section 2.3;

(vi) notwithstanding anything to the contrary in this Article 4, the aggregate Title Defect Amounts attributable to the effects of all Title Defects upon any Title Defect Property shall not exceed the Allocated Value of such Title Defect Property; and

(vii) if the Parties agree on the remedy set forth in Section 3.2(c)(i) but the Parties do not agree by the scheduled Closing with respect to any Title Defect Amounts relating thereto, then the provisions of Section 3.2 and Section 3.4 shall apply.

Section 3.3 Title Benefits.

(a) In addition to any Title Benefits reported by Investor pursuant to Section 3.2, EXCO Parent has the right, but not the obligation, to deliver to Investor on or before the Defect Claim Date with respect to each Title Benefit discovered by EXCO Parent a notice (a “Title Benefit Notice”) in writing and including (i) a description of the Title Benefit reasonably sufficient to determine the basis of the alleged Title Benefit, (ii) the Subject Well affected by such Title Benefit (a “Title Benefit Property”), (iii) the Allocated Value of each Title Benefit Property, (iv) EXCO Parent’s estimate of the Title Benefit Amount attributable to the Title Benefit and the computations and information upon which EXCO Parent’s belief is based on or before the Defect Claim Date with respect to each Title Benefit discovered by EXCO Parent. EXCO Parent shall deliver to Investor copies of all documents upon which EXCO Parent relies for its assertion of a Title Benefit, including, at a minimum, supporting documents reasonably necessary for Investor (as well as any title attorney or examiner hired by Investor) to verify the existence of the alleged Title Benefit.

(b) With respect to each Title Benefit Property affected by any Title Benefits reported under Section 3.2(a) or Section 3.3(a), the Title Benefit Amount attributable to such Title Benefit shall be used to reduce the amount of the aggregate Title Defect Amounts and Remedy Amounts attributable to Title Defects and Environmental Defects properly and timely raised by Investor after taking into account the Individual Title Defect Threshold and the Individual Environmental Defect Threshold, as applicable.

(c) The Title Benefit Amount resulting from a Title Benefit shall be the amount by which the Allocated Value of the Title Benefit Property affected by such Title Benefit is increased as a result of the existence of such Title Benefit and shall be determined in accordance with the following methodology, terms and conditions:

(i) if Investor and EXCO Parent agree on the Title Benefit Amount, that amount shall be the Title Benefit Amount;

(ii) if the Title Benefit reflects a difference (with a proportional increase in the Working Interest for the affected Title Defect Property) between (A) the Net Revenue Interest for the affected Title Benefit Property and (B) the Net Revenue Interest stated in Schedule 2.4 or Schedule 3.2 (as applicable), then the Title Benefit Amount shall be the product of the Allocated Value of such Title Benefit Property multiplied by a fraction, the numerator of which is the amount of the Net Revenue Interest increase and the denominator of which is the Net Revenue Interest stated in Schedule 2.4 or Schedule 3.2 (as applicable); and

(iii) if the Title Benefit represents a benefit in the ownership or title to the Title Benefit Property of a type not described in subsection (ii) above, the Title Benefit Amount shall be determined by taking into account the Allocated Value of the Title Benefit Property, the portion of the Title Benefit Property benefitted by the Title Benefit, the legal effect of the Title Benefit, the potential economic effect of the Title Benefit over the life of the Title Benefit Property and such other factors as are necessary to make a proper evaluation.

(d) If the Parties cannot reach an agreement on alleged Title Benefits or Title Benefit Amounts (in each case, a “Disputed Title Benefit”) by the scheduled Closing, then (i) the average of EXCO’s and Investor’s good faith estimate of such disputed Title Benefit Amount shall be used in calculating the reduction to the Title Defect Amounts and Remedy Amounts pursuant to Section 3.3(b) to the extent applicable, and (ii) the provisions of Section 3.4 shall apply.

Section 3.4 Title Disputes.

(a) If, after the Remedy Deadline, the Parties are unable to agree on any Disputed Title Defects or Disputed Title Benefits (the “Disputed Title Matters”) such dispute(s), and only such dispute(s), shall be exclusively and finally resolved in accordance with the following provisions of this Section 3.4. Investor shall provide to EXCO Parent by not later than the tenth Business Day following the Remedy Deadline a written description meeting the requirements of Section 3.2(a) or Section 3.3(a), as applicable, together with supporting documentation, of the Disputed Title Matters. By not later than ten Business Days after EXCO Parent’s receipt of Investor’s written description of the Disputed Title Matters, EXCO Parent shall provide to Investor a written response setting forth EXCO Parent’s position with respect to the Disputed Title Matters together with supporting documentation.

(b) By not later than ten Business Days after Investor’s receipt of EXCO Parent’s written response to Investor’s written description of the Disputed Title Matters and supporting documentation, either EXCO or Investor may initiate a non-administered arbitration of any such dispute(s) conducted in accordance with the Commercial Arbitration Rules of the AAA, to the extent that such rules do not conflict with the terms of this Section 3.4, by written notice (the “Title Arbitration Notice”) to the other Party of any Disputed Title Matters not otherwise resolved or waived that are to be resolved by arbitration (“Final Disputed Title Matters”).

(c) The arbitration shall be held before a one member arbitration panel (the “Title Arbitrator”), determined as follows. The Title Arbitrator shall be an attorney with at least 15 years’ experience examining oil and gas titles in the State of Texas. Within two Business Days following the receipt by EXCO or Investor of the Title Arbitration Notice from the other Party, EXCO Parent and Investor shall each exchange lists of three acceptable, qualified arbitrators. Within two Business Days following the exchange of lists of acceptable arbitrators, the Parties shall select by mutual agreement the Title Arbitrator from their original lists of three acceptable arbitrators. If no such agreement is reached within five Business Days following the delivery of Title Arbitration Notice, the Houston, Texas office of the AAA shall select an arbitrator from the original lists provided by the Parties to serve as the Title Arbitrator.

(d) Within two Business Days following the selection of the Title Arbitrator, the following initial information shall be submitted to the Title Arbitrator (with copies to the other Parties): (i) EXCO Parent shall submit a copy of this Agreement, with specific reference to this Section 3.4 and the other applicable provisions of this Article 3; (ii) Investor shall submit a copy of Investor’s written description of the Final Disputed Title Matters, together with the supporting documents that were provided to EXCO Parent; (iii) EXCO Parent shall submit a copy of EXCO Parent’s written response to Investor’s written description of the Final Disputed Title Matters, together with the supporting documents that were provided to Investor; and (iv) EXCO Parent shall submit a copy of the Title Arbitration Notice. The Parties may then supplement such initial information with one final supplement and/or response to the other Party’s position with respect to the Final Disputed Title Matters submitted to the Title Arbitrator within three Business Days after all of such initial information has been submitted. The Title Arbitrator shall resolve the Final Disputed Title Matters based only on the foregoing submissions. Neither Investor nor EXCO Parent shall have the right to submit additional documentation to the Title Arbitrator nor to demand discovery on the other Party.

(e) The Title Arbitrator shall make its determination by written decision within 20 Business Days following his/her selection pursuant to Section 3.4(c) (the “Title Arbitration Decision”). The Title Arbitration Decision shall be final and binding upon the Parties, without right of appeal. In making his/her determination, the Title Arbitrator shall be bound by the provisions of this Article 3. The Title Arbitrator may consult with and engage disinterested Third Parties (including Louisiana counsel if any Final Disputed

Title Matter relates to properties located in Louisiana) to advise the Title Arbitrator, but shall disclose to the Parties the identities of such consultants and shall only use such Third Parties to the extent necessary to resolve the Final Disputed

Title Matters. Any such consultant shall not have worked as an employee or consultant for either Party or its Affiliates during the five-year period preceding the arbitration nor have any financial interest in the dispute.

(f) The Title Arbitrator shall act as an expert for the limited purpose of determining the specific disputed Title Defects and Title Defect Amounts or Title Benefits and Title Benefit Amounts and shall not be empowered to award damages, interest or penalties to either Party with respect to any matter.

(g) The fees, costs and expenses of the Title Arbitrator, shall be allocated between EXCO Parent, on the one hand, and Investor, on the other hand, based upon the percentage which the portion of the Disputed Title Matters not awarded to such Party bears to the amount actually contested by such Party. For example, if Investor claims that the appropriate adjustments are $1,000 greater than the amount determined by EXCO Parent and if the Title Arbitrator ultimately resolves the Disputed Title Matters by awarding to Investor $300 of the $1,000 contested, then the fees, costs and expenses of the Title Arbitrator will be allocated 30% (i.e., 300 ÷ 1,000) to EXCO Parent and 70% (i.e., 700 ÷ 1,000) to Investor. Each Party shall each bear its own legal fees and other costs of preparing and presenting its case.

(h) The Parties shall implement the Title Arbitration Decision as follows: (i) in the case of alleged Title Defects determined to be Title Defects, EXCO Parent shall remedy, at its sole election, such Title Defects pursuant to Section 3.2(c) in a manner reasonably satisfactory to Investor within ten Business Days following EXCO Parent’s receipt of the Title Arbitration Decision (with any amounts owed, as a result of such election, to be made and accounted for at the times set forth in Section 10.5(b)), (ii) in the case of disputed Title Defect Amounts or where an alleged Title Defect is determined to be a Title Defect and remains uncured ten Business Days following EXCO Parent’s receipt of the Title Arbitration Decision, any amounts determined to be owed by either Party shall be accounted for in accordance Section V.c, Section V.d or Section V.e of Annex A, as applicable, and the Parties shall effect the actions required thereby in connection therewith. Any alleged Title Defects determined not to be Title Defects or alleged Title Benefits determined not to be Title Benefits (in each case) under the Title Arbitration Decision shall be final and binding as not being Title Defects or Title Benefits, as applicable.

(i) Any dispute over the interpretation or application of this Section 3.4 shall be decided by the Title Arbitrator with reference to the Laws of the State of Texas.

Section 3.5 Limitations on Applicability.

(a) The right of Investor or EXCO Parent to assert a Title Defect or Title Benefit, respectively, under this Article 3 shall terminate on the Defect Claim Date, except that until the alleged Title Defect or Title Benefit or Title Defect Amount or Title

Benefit Amount, as applicable, is resolved in accordance with this Agreement, there shall be no termination of Investor’s or EXCO Parent’s rights under this Article 3 with respect to any alleged Title Defect or Title Benefit properly reported in accordance with Section 3.4 on or before the Defect Claim Date. Thereafter, except pursuant to the special warranty of title set forth in the Production Assets Assignments, Investor (on its own behalf and on behalf of the Partnership Entities) shall be deemed to have waived any Title Defect of which Investor has not provided notice prior to the Defect Claim Date. Notwithstanding the foregoing, if a Title Defect under this Article 3 results from any matter that could also result in the breach of any representation or warranty of EXCO Parent as set forth in Article 5 or a breach of any EXCO Party’s special warranty of title set forth in the Production Assets Assignments and (in either case) (i) Investor has Actual Knowledge of such matter prior to the Defect Claim Date after consultation with its consultants and counsel engaged by Investor to conduct title due diligence or (ii) the Title Defect was apparent from a recorded instrument to which EXCO or its Affiliate is or was a party which was recorded prior to the Effective Time, then, other than a Title Defect consisting of an EXCO Transfer or Lien arising by through or under EXCO or an Affiliate of EXCO, Investor shall only be entitled to assert such matter as a Title Defect to the extent permitted by this Article 3 and, for the avoidance of doubt, Investor and the Partnership Entities shall be precluded from also asserting such matter as the basis of the breach of any such representation or warranty or as a claim against any EXCO Party’s special warranty of title provided in the Production Assets Assignments.

(b) Notwithstanding anything to the contrary in this Agreement, in no event shall there be any adjustments to the Transaction Items or other remedies available in respect of Title Defects under this Article 3 (i) for any Title Defect Amount with respect to an individual Title Defect if such amount does not exceed $25,000 (each, an “Individual Title Defect Threshold”); and (ii) with respect to any Title Defect Amount that exceeds the Individual Title Defect Threshold unless (A) the amount of (1) the sum of (x) all of the Title Defect Amounts of such Title Defects that exceed the Individual Title Defect Threshold (for the avoidance of doubt, including the portion of such Title Defect Amounts that is less than the Individual Title Defect Threshold), excluding any Title Defect Amounts attributable to Title Defects cured by EXCO Parent or waived by Investor, plus (y) the Remedy Amounts of all Environmental Defects, in the aggregate, excluding any individual Environmental Defect for which the Remedy Amount does not exceed the Individual Environmental Threshold and excluding any Environmental Defects cured by EXCO Parent or waived by Investor, minus (2) all Title Benefit Amounts attributable to Title Benefits, exceeds (B) the Aggregate Defect Deductible after which point, subject to the Individual Title Defect Threshold, Investor shall be entitled to adjustments to the Transaction Items or other remedies chosen by Investor and EXCO Parent in accordance with Section 3.2(c) only with respect to Title Defect Amounts in excess of such Aggregate Defect Deductible and only to the extent that Title Defect Amounts exceed the Aggregate Defect Deductible. If any Asset is excluded pursuant to Section 3.2(c), the Title Defect Amount relating to such excluded Asset will not be counted towards the Aggregate Defect Deductible.

Section 3.6 Consents to Assignment and Preferential Rights to Purchase.

(a) Promptly after the Execution Date, EXCO Parent shall prepare and send (i) notices to the holders of any required consents to assignment that are set forth in Schedule 5.13B (including the Specified Consent Requirements that are set forth in Schedule 5.13B) requesting consents to the Production Assets Assignments and, if applicable, the transactions contemplated hereby, and (ii) notices to the holders of any applicable preferential rights to purchase or similar rights that are set forth in Schedule 5.13A in compliance with the terms of such rights and requesting waivers of such rights. EXCO Parent shall use commercially reasonable efforts to cause such consents to assignment and waivers of preferential rights to purchase or similar rights (or the exercise thereof) to be obtained and delivered prior to Closing, provided that EXCO Parent shall not be required to make payments or undertake obligations to or for the benefit of the holders of such rights in order to obtain the required consents and waivers. Investor shall cooperate with EXCO Parent in seeking to obtain such consents to assignment and waivers of preferential rights, provided that Investor shall not be required to make payments or undertake obligations to or for the benefit of the holders of such rights in order to obtain the required consents and waivers. Any preferential purchase right must be exercised subject to all terms and conditions set forth in this Agreement (including all thresholds, deductibles and other amounts except for the cash consideration), including the successful Closing of this Agreement pursuant to Article 8 as to those Assets for which preferential purchase rights have not been exercised; provided, however, that the exercise of such preferential purchase rights will be for cash consideration only (based on the Allocated Value) and no partnership with the holder of such right will be formed pursuant hereto. The consideration payable under this Agreement for any particular Asset for purposes of preferential purchase right notices shall be the Allocated Value for such Asset, subject to adjustment pursuant to Section 2.2(a) and Section 2.2(b). If, prior to the Closing Date, any Party discovers any required consents or preferential rights to purchase (applying to the Assets) for which notices have not been delivered pursuant to the first sentence of this Section 3.6(a), then, without limiting any rights for indemnification pursuant to Section 12.2(b)(ii) on account of a breach of EXCO’s representations set forth in Section 5.13, (A) the Party making such discovery shall provide the other Party with written notification of such consents or preferential rights, as applicable, (B) EXCO Parent, following delivery or receipt of such written notification, as applicable, will promptly send notices to the holders of the required consents requesting consents to the Production Assets Assignments and, if applicable, the transactions contemplated hereby, and notices to the holders of preferential rights to purchase in compliance with the terms of such rights and requesting waivers of such rights and (C) the terms and conditions of this Section 3.6 shall apply to the Assets subject to such consents or preferential rights to purchase, as applicable.

(b) No Asset for which a Specified Consent Requirement has not been satisfied shall be included in any of the Production Assets Assignments. In cases in which the Asset subject to such a requirement is a Contract and MLP LLC is assigned the other Assets to which the Contract relates, but the Contract is not transferred to MLP LLC due to the unwaived Specified Consent Requirement, then, to the extent practicable, (i) EXCO Parent shall continue after Closing to use commercially reasonable efforts to satisfy the Specified Consent Requirement so that such Contract can be transferred to MLP LLC upon receipt of the Specified Consent Requirement, (ii) the Contract shall be

held by the applicable EXCO Party for the benefit of MLP LLC until the Specified Consent Requirement is satisfied or the Contract has terminated, and (iii) MLP LLC shall pay all amounts due thereunder, perform all obligations thereunder and, subject to the rights of MLP LLC under the Related Agreements, indemnify the EXCO Parties and their Affiliates against any Damages incurred or suffered by any such EXCO Party or Affiliate as a consequence of an EXCO Party remaining a party to such Contract (in each case, except to the extent any such Damages resulted from the gross negligence or willful misconduct of any EXCO Party or its Representatives and subject to the same requirements and procedures applicable to Article 7 of the Administrative Services Agreement, applied mutatis mutandis) until the Specified Consent Requirement is satisfied or the Contract has terminated. In cases in which the Asset subject to such a Specified Consent Requirement is a Property or other real property interest and such consent is not satisfied by Closing, the affected Asset (and any Assets solely related to such Asset) shall not be transferred pursuant to the Production Assets Assignments, and the Transaction Items shall be appropriately adjusted in accordance with Section III.a of Annex A based upon the Allocated Value of such Asset. In such event, unless and until such Assets are thereafter transferred to MLP LLC as provided in Section 3.6(c) and subject to the foregoing provisions (including MLP LLC’s indemnification obligations under this Section 3.6(b), which provisions shall control in event of any conflict with the other provisions of this Agreement), such excluded Assets (and any Assets solely related to such Assets), shall no longer be included within the definition of Assets or Production Assets (or EXCO Parent Assets or EOC Assets, as applicable) for any purpose under this Agreement and shall become an Excluded Asset hereunder, and the Assumed Obligations shall not include liabilities or obligations relating to such Excluded Assets.

(c) If an unsatisfied Specified Consent Requirement with respect to which an adjustment to the Transaction Items is made under Section 2.3 is subsequently satisfied prior to the fifth Business Day prior to Final Statement Date, a separate closing shall be held within five Business Days thereof at which (i) the applicable EXCO Party shall contribute and convey the affected Assets to MLP LLC in accordance with this Agreement, and (ii) the Parties shall take the actions required by Section III.b of Annex A on the account of such contribution of such Assets.

(d) If such consent requirement is not satisfied by the date of delivery of the final settlement statement, the EXCO Parties shall have no further obligation to contribute and convey such Assets to MLP LLC, and such Assets (and any Assets solely related to such Assets) shall be deemed to be deleted from the Exhibits and Schedules to this Agreement for all purposes. For any required consent that is not a Specified Consent Requirement, notwithstanding anything herein to the contrary, but subject to the rights for indemnification pursuant to Section 12.2(b) on account of a breach of EXCO’s representations set forth in Section 5.13, MLP LLC shall be responsible from and after the Closing for any and all liabilities arising from the failure to obtain such consent except to the extent that the failure to obtain such consent results from the breach by any of the EXCO Parties of its covenants set forth in this Section 3.6.

(e) If any preferential right to purchase any Assets is exercised prior to the Reorganization or the Closing (as applicable), the Transaction Items shall be adjusted in accordance with Section III.a of Annex A based upon the Allocated Value of such Assets, and the affected Assets (and any Assets solely related to such Assets) shall be deemed to be deleted from Exhibits and Schedules to this Agreement for all purposes. The applicable EXCO Party shall retain the consideration paid by the Third Party. Should a Third Party fail to exercise its preferential right to purchase as to any portion of the Assets prior to the Reorganization or the Closing (as applicable) and the time for exercise or waiver has not yet expired, the affected Assets (and any Assets solely related to such Assets) shall not be transferred to MLP LLC pursuant to the Production Assets Assignments and the Transaction Items shall be adjusted in accordance with Section III.a of Annex A based upon the Allocated Value of such Assets. In the event that such Third Party exercises its preferential right to purchase following the Closing, the EXCO Parties shall have no further obligation to contribute and convey such Assets to MLP LLC, and such Assets shall be deemed to be deleted from the Exhibits and Schedules to this Agreement for all purposes and shall constitute Excluded Assets hereunder. If, on the other hand, the applicable preferential purchase rights are waived or expire (including based on the failure of a Third Party holder of an exercised preferential purchase right to consummate the purchase of the affected Assets) on the fifth Business Day prior to the Final Statement Date, then a separate closing shall be held within five Business Days thereof at which (i) the applicable EXCO Party shall contribute and convey such affected Assets to MLP LLC in accordance with this Agreement and (ii) the Parties shall take the actions required by Section III.b of Annex A on the account of such contribution of such Assets. With respect to any Assets excluded from the transactions contemplated hereby pursuant to this Section 3.6(e) (unless and until such Assets are thereafter transferred to MLP LLC as provided in this this Section 3.6(e)), such excluded Assets shall constitute Excluded Assets hereunder and, for the avoidance of doubt, the Assumed Obligations shall not include liabilities and obligations relating to such Excluded Assets.

Section 3.7 Maintenance of Uniform Interest Waivers.

(a) Promptly after the Execution Date, EXCO Parent shall prepare and send notices to the Working Interests owners (the “WI Owners”) that are parties with an EXCO Party to one or more of those joint operating agreements affecting the Properties that contain a maintenance of uniform interest provision (“MUI”) and that are set forth in Schedule 5.13C. EXCO Parent shall use commercially reasonable efforts to cause waivers of such MUIs to be obtained and delivered prior to undertaking the Reorganization, provided that EXCO Parent shall not be required to make payments or undertake obligations to or for the benefit of the holders of such rights in order to obtain such waivers. Investor shall cooperate with EXCO Parent in seeking to obtain such waivers of the MUIs; provided that Investor shall not be required to make payments or undertake obligations to or for the benefit of the holders of such rights in order to obtain such waivers. If, prior to the Closing Date, any Party discovers any joint operating agreements affecting the Properties and containing a MUI for which notices have not been delivered pursuant to the first sentence of this Section 3.7(a), then, without limiting the rights for indemnification pursuant to Section 12.2(b)(ii) on account of a breach of EXCO’s representations set forth in Section 5.13, (i) the Party making such discovery shall provide the other Party with written notification of such MUIs, (ii) EXCO Parent, following delivery or receipt of such written notification, will promptly send notices to the WI Owners that are subject to such MUIs requesting waivers of such MUIs, and (iii) the terms and conditions of this Section 3.7 shall apply to the Assets subject to such MUIs.

(b) Unless the Parties otherwise agree in writing, no Asset for which less than all of the waivers of the MUI affecting such Asset from the applicable WI Owners subject thereto have been received shall be included in any of the Production Assets Assignments. Unless the Parties otherwise agree in writing, if any such waivers of an MUI affecting an Assets are not obtained, then the Asset affected thereby (and any Assets solely related thereto) shall not be transferred pursuant to the Production Assets Assignments and the Transaction Items shall be adjusted in accordance with Section III.a of Annex A. If all of the waivers of such MUI are subsequently obtained prior to the fifth Business Day prior to the Final Statement Date, a separate closing shall be held within five Business Days thereof at which (i) the applicable EXCO Party shall contribute and convey such Assets to MLP LLC in accordance with this Agreement and (ii) the Parties shall take the actions required by Section III.b of Annex A on account of the such contribution of such Assets. If all of such waivers are not obtained by the Final Statement Date, then the EXCO Parties shall have no further obligation to contribute and convey such Assets to MLP LLC, and such Assets shall be deemed to be deleted from the Exhibits and Schedules to this Agreement for all purposes. With respect to any Assets excluded from the transactions contemplated hereby pursuant to this Section 3.7 (unless and until such Assets are thereafter transferred to MLP LLC as provided in this Section 3.7(b)), such excluded Assets shall constitute Excluded Assets hereunder and, for the avoidance of doubt, the Assumed Obligations shall not include liabilities and obligations relating to such Excluded Assets.

Section 3.8 Casualty or Condemnation Loss.

ENVIRONMENTAL MATTERS

Section 4.1 Environmental Defects.

(a) To assert a claim of an Environmental Defect, Investor must deliver a claim notice to EXCO Parent (a “Environmental Defect Notice”) promptly after the discovery thereof, but in no event later than the Defect Claim Date. Investor shall also, from time to time prior to the Defect Claim Date, use its good faith efforts to furnish EXCO Parent with written notice of any Environmental Defect that is discovered by Investor or any of its Representatives while conducting Investor’s due diligence with respect to the Assets prior to the Defect Claim Date. To be effective, each Environmental Defect Notice shall be in writing and (i) include a description of the alleged Environmental Defect that is reasonably sufficient for EXCO Parent to determine the basis of the alleged Environmental Defect, (ii) identify the Asset adversely affected by the Environmental Defect (a “Environmental Defect Property”), (iii) set forth the Allocated Value of each Environmental Defect Property, and (iv) specify Investor’s estimate of the Remedy Amount with respect to the alleged Environmental Defect and the computations and information upon which Investor’s belief is based, including any analysis by any environmental consultant hired by Investor. Investor shall furnish to EXCO Parent copies of all documents upon which Investor relies for its assertion of an Environmental Defect, including, at a minimum, supporting documents in Investor’s possession reasonably necessary for EXCO Parent (as well as any Environmental attorney or examiner hired by EXCO Parent) to verify the existence of the alleged Environmental Defect.

(b) EXCO Parent shall have the right, but not the obligation, to attempt, at its sole cost, to Remedy (or cause to be Remedied) on or before the Closing Date any Environmental Defects for which EXCO Parent has received an Environmental Defect Notice from Investor prior to the Defect Claim Date.

(c) In the event that any Environmental Defect is not waived by Investor or Remedied prior to Closing, or any dispute exists as to whether an Environmental Defect exists or a Remedy has been effected, EXCO Parent and Investor shall mutually agree upon one of the following actions (subject to the Individual Environmental Defect Threshold and the Aggregate Defect Deductible):

(i) make an adjustment to the Transaction Items pursuant to (x) Section II.a of Annex A if the Remedy Amount applicable to such Environmental Defect is agreed by the Parties or (y) Section IV.a of Annex A if the Remedy Amount applicable to such Environmental Defect is disputed by the Parties;

(ii) have the applicable EXCO Party retain the entirety of the Environmental Defect Property (and any other Assets solely related to such Environmental Defect Property) that is adversely affected by such Environmental Defect in which event the Transaction Items shall be adjusted in accordance with Section II.a of Annex A based upon the Allocated Value of such Environmental Defect Property and such Environmental Defect Property (and any other Assets solely related to such Environmental Defect Property) shall no longer be included within the definition of Assets or Production Assets (or EXCO Parent Assets or EOC Assets, as applicable) for any purpose under this Agreement and shall become an Excluded Asset hereunder, and the Assumed Obligations shall not include liabilities or obligations relating to such Excluded Assets; or

With respect to any Environmental Defect, if Investor and EXCO Parent cannot agree upon the remedy for such Environmental Defect under Section 4.1(c)(i), Section 4.1(c)(ii) or Section 4.1(c)(iii) above prior to Closing, then Investor and EXCO Parent shall be deemed to have chosen the remedy under Section 4.1(c)(ii) with respect to such Environmental Defect.

Section 4.2 Environmental Disputes.

(a) The Parties shall attempt to agree on all Environmental Defects and Remedy Amounts prior to Closing. If the Parties are unable to agree on the existence of any Environmental Defect that is not excluded pursuant to Section 4.1(c)(ii) or if the Parties are unable to agree on any Remedy Amounts for which an adjustment is to be made to the Transaction Items pursuant to Section 4.1(c)(i), (in each case) by the scheduled Closing, then the average of EXCO’s and Investor’s good faith estimate of the Remedy Amount relating thereto shall be used to determine the adjustments to the Transaction Items pursuant to Section IV.a of Annex A. If, after the Closing, the Parties are unable to agree on an alleged Environmental Defect or the Remedy Amount (the “Disputed Environmental Matters”) such dispute(s), and only such dispute(s), shall be exclusively and finally resolved in accordance with the following provisions of this

Section 4.2. Investor shall provide to EXCO Parent by not later than the tenth Business Day following the Closing a written description meeting the requirements of Section 4.1(a), together with all supporting documentation, of the Disputed Environmental Matters. By not later than ten Business Days after EXCO Parent’s receipt of Investor’s written description of the Disputed Environmental Matters, EXCO Parent shall provide to Investor a written response setting forth EXCO Parent’s position with respect to the Disputed Environmental Matters, together with all supporting documentation.

(b) By not later than 15 Business Days after Investor’s receipt of EXCO Parent’s written response and supporting documentation to Investor’s written description of the Disputed Environmental Matters, either EXCO or Investor may initiate a non-administered arbitration of any such dispute(s) conducted in accordance with the Commercial Arbitration Rules of the AAA, to the extent that such rules do not conflict with the terms of this Section 4.2, by written notice (the “Environmental Arbitration Notice”) to the other Party of any Disputed Environmental Matters not otherwise resolved or waived that are to be resolved by arbitration (“Final Disputed Environmental Matters”).

(c) The arbitration shall be held before a one member arbitration panel (the “Environmental Arbitrator”), determined as follows. The Environmental Arbitrator shall be an attorney with at least 15 years’ experience in environmental law in the State of Texas. Within two Business Days following the receipt by EXCO or Investor of the Environmental Arbitration Notice from the other Party, EXCO Parent and Investor shall each exchange lists of three acceptable, qualified arbitrators. Within two Business Days following the exchange of lists of acceptable arbitrators, the Parties shall select by mutual agreement the Environmental Arbitrator from their original lists of three acceptable arbitrators. If no such agreement is reached within five Business Days following the delivery of Environmental Arbitration Notice, the Houston, Texas office of the AAA shall select an arbitrator from the original lists provided by the Parties to serve as the Environmental Arbitrator.

(d) Within two Business Days following the selection of the Environmental Arbitrator, the following initial information shall be submitted to the Environmental Arbitrator (with copies to the other Parties): (i) EXCO Parent shall submit a copy of this Agreement, with specific reference to this Section 4.2 and the other applicable provisions of this Article 4, (ii) Investor shall submit a copy of Investor’s written description of the Final Disputed Environmental Matters, together with the supporting documents that were provided to EXCO Parent, (iii) EXCO Parent shall submit a copy of EXCO Parent’s written response to Investor’s written description of the Final Disputed Environmental Matters, together with the supporting documents that were provided to Investor and (iv) EXCO Parent shall submit a copy of the Environmental Arbitration Notice. The Parties may then supplement such initial information with one final supplement and/or response to the other Party’s position with respect to the Final Disputed Environmental Matters submitted to the Environmental Arbitrator within three Business Days after all of such initial information has been submitted. The Environmental Arbitrator shall resolve the Final Disputed Environmental Matters based only on the foregoing submissions. Neither Investor nor EXCO Parent shall have the right to submit additional documentation to the Environmental Arbitrator nor to demand discovery on the other Party.

(e) The Environmental Arbitrator shall make its determination by written decision within 20 Business Days following his/her selection pursuant to Section 4.2(c) (the “Environmental Arbitration Decision”). The Environmental Arbitration Decision shall be final and binding upon the Parties, without right of appeal. In making his/her determination, the Environmental Arbitrator shall be bound by the provisions of this Article 4. The Environmental Arbitrator may consult with and engage disinterested Third Parties (including Louisiana counsel if any Final Disputed Environmental Matter relates to properties located in Louisiana) to advise the Environmental Arbitrator, but shall disclose to the Parties the identities of such consultants and shall only use such Third Parties to the extent necessary to resolve the Final Disputed Environmental Matters. Any such consultant shall not have worked as an employee or consultant for either Party or its Affiliates during the five-year period preceding the arbitration nor have any financial interest in the dispute.

(f) The Environmental Arbitrator shall act as an expert for the limited purpose of determining the specific disputed Environmental Defects and Remedy Amounts and shall not be empowered to award damages, interest or penalties to either Party with respect to any matter.

(g) The fees, costs and expenses of the Environmental Arbitrator, shall be allocated between EXCO Parent, on the one hand, and Investor, on the other hand, based upon the percentage which the portion of the disputed matters not awarded to such Party bears to the amount actually contested by such Party. Each Party shall each bear its own legal fees and other costs of preparing and presenting its case.

(h) The Parties shall implement the Environmental Arbitration Decision with respect to which the Parties chose the remedy set forth in Section 4.1(c)(i) by taking the actions required by Section IV.b, Section IV.c or Section IV.d, of Annex A, as applicable, based upon the finally determined Remedy Amount (or, if the alleged Environmental Defect is determined not to have been an Environmental Defect, based upon a Remedy Amount of $0).

(i) Any dispute over the interpretation or application of this Section 4.2 shall be decided by the Environmental Arbitrator with reference to the Laws of the State of Texas.

Section 4.3 Limitations on Applicability.

(a) The right of Investor to assert an Environmental Defect under this Article 4 shall terminate on the Defect Claim Date, except that until the alleged Environmental Defect or Remedy Amount, as applicable, is resolved in accordance with this Agreement, there shall be no termination of Investor’s rights under this Article 4 with respect to any alleged Environmental Defect properly reported in accordance with Section 4.1 on or before the Defect Claim Date. Except for Investor’s rights for any breach by EXCO of Section 5.18, Investor (on its own behalf and on behalf of the Partnership Entities) shall be deemed to have waived any Environmental Defect of which Investor has not provided notice prior to the Defect Claim Date.

(b) Notwithstanding anything to the contrary in this Agreement, in no event shall there be any adjustments to the Transaction Items or other remedies available in respect of Environmental Defects under this Article 4 (i) for any Remedy Amount with respect to an individual Environmental Defect Property if such amount does not exceed $75,000 (each, an “Individual Environmental Defect Threshold”); and (ii) with respect to any Remedy Amount that exceeds the Individual Environmental Defect Threshold unless (A) the amount of (1) the sum of (x) all of the Remedy Amounts of such Environmental Defects that exceed the Individual Environmental Defect Threshold (for the avoidance of doubt, including the portion of such Remedy Amounts that is less than the Individual Environmental Defect Threshold), excluding any Remedy Amounts attributable to Environmental Defects cured by EXCO Parent or waived by Investor, plus (y) the Title Defect Amounts of all Title Defects, in the aggregate, excluding any individual Title Defect for which the Title Defect Amount does not exceed the Individual Title Defect Threshold and excluding any Title Defects cured by EXCO Parent or waived by Investor, minus (2) all Title Benefit Amounts attributable to Title Benefits, exceeds (B) the Aggregate Defect Deductible after which point, subject to the Individual Environmental Defect Threshold, Investor shall be entitled to the adjustments to the Transaction Items or other remedies chosen by Investor and EXCO Parent in accordance with Section 4.1(c) only with respect to Remedy Amounts in excess of such Aggregate Defect Deductible and only to the extent that Remedy Amounts exceed the Aggregate Defect Deductible. If any Asset is excluded pursuant to Section 4.1(c)(ii), the Remedy Amount relating to such excluded Asset will not be counted towards the Aggregate Defect Deductible.

(c) Without prejudice to any of the other dates by which performance or the exercise of rights is due hereunder, or the Parties’ rights or obligations in respect thereof, the Parties hereby acknowledge that, as set forth more fully in Section 14.15, time is of the essence in performing their obligations and exercising their rights under this Article 4, and, as such, that each and every date and time by which such performance or exercise is due shall be the firm and final date and time.

EXCO shall supply

reasonable documentation available to support any credit, charge, receipt or other item included in the Final Settlement Statement, including the Vernon Working Capital. Following delivery of the Final Settlement Statement, EXCO Parent shall provide the Investor with such information, and access to those employees of EXCO Parent and its subsidiaries, as the Investor reasonably requests in connection with the Investor’s review and examination of such statement. Investor, on behalf of the Partnership Entities shall deliver to EXCO Parent a written report containing any changes that such Persons propose be made to the Final Settlement Statement no later than the 60th day following the Investor’s receipt thereof.

(c) In the event that the Parties cannot reach agreement within the Final Statement Review Period, any Party may refer the remaining matters in dispute to the Houston, Texas office of Ernst & Young LLP or such other Person as may be selected pursuant to this Section 10.5(c) (the “Accounting Arbitrator”) for review and final determination by arbitration. Should Ernst & Young LLP fail or refuse to agree to serve as Accounting Arbitrator within ten days after receipt of a written request from any Party to serve, the Parties shall request another nationally recognized accounting firm to serve as Accounting Arbitrator. Should such selected firm fail or refuse to agree to serve as Accounting Arbitrator within ten days after receipt of a written request from any Party to serve, and should the Parties fail to agree in writing on another replacement Accounting Arbitrator within five days after the end of that ten day period, or should no replacement Accounting Arbitrator agree to serve within 30 days after the original written request pursuant to this Section, the Accounting Arbitrator shall be a nationally recognized accounting firm appointed by the Houston office of the American Arbitration Association (the “AAA”).

In determining the proper amount of any adjustment to the Cash Adjustment Amount, the Accounting Arbitrator shall not increase the Cash Adjustment Amount more than the increase proposed by EXCO Parent nor decrease the Cash Adjustment Amount more than the decrease proposed by Investor, as applicable. The Accounting Arbitrator shall act as an expert for the limited purpose of determining the specific disputed matters submitted by the Parties with respect to the Final Settlement Statement and may not award damages or penalties to the Parties with respect to any matter. Investor and EXCO Parent shall each bear its own legal fees and other costs of presenting its case. The fees, costs and expenses of the Accounting Arbitrator, shall be allocated between EXCO Parent, on the one hand, and the Investor, on the other hand, based upon the percentage which the portion of the disputed matters not awarded to such Party bears to the amount actually contested by such Party.

(d) Within five Business Days after the date on which the Cash Adjustment Amount is finally determined in accordance with Section 10.5(b) or Section 10.5(c), as applicable, (A) Investor shall pay to EXCO Parent 74.5% of the amount by which the final Cash Adjustment Amount exceeds the Cash Adjustment Amount used to determine the Cash Contribution at Closing or (B) EXCO Parent shall pay to the Investor 74.5% of the amount by which the Cash Adjustment Amount used to determine Cash Contribution at Closing exceeds the final Cash Adjustment Amount, as applicable.

(e) All payments made or to be made under this Agreement shall be made by electronic transfer of immediately available funds to the accounts designated in writing by the applicable recipient.

(f) In the event that any assets are contributed to MLP LLC pursuant to Article 3 or Article 4 following the Final Statement Date which assets, if included in the Assets at Closing, would have resulted in changes to the Cash Adjustment Amount, the Parties shall repeat the procedures above, applied mutatis mutandis (but with such shorter time periods as the parties may agree) in order to give effect to the intent of this Section 10.5. Such procedure shall be replicated no more than once every 90 days (or such shorter period as the Parties may agree).

(f) by either EXCO Parent or Investor if the sum of (i) all Title Defect Amounts (or, to the extent applicable in lieu thereof, Reference Title Defect Amounts) which would adjust the Transaction Items as of Closing (taking into account any off-setting Title Benefits but excluding any Title Defect Amounts attributable to Title Defects cured by EXCO prior to Closing), (ii) all Remedy Amounts (or, to the extent applicable in lieu thereof, Averaged Remedy Amounts) which would adjust the Transaction Items as of Closing (excluding any Remedy Amounts attributable to Environmental Defects cured by EXCO prior to Closing) and (iii) the Allocated Values of all of the Assets excluded pursuant to Article 3, Article 4 or Section 7.4 shall not, in the aggregate, exceed $70,000,000;

Section 11.2 Effect of Termination. If this Agreement is terminated pursuant to Section 11.1, this Agreement shall become void and of no further force or effect (except for the provisions of Section 1.1, Section 5.6, Section 6.6, Section 7.1(d), Section 7.3, Section 7.10(b), Section 11.1, this Section 11.2, Section 11.3, Section 11.4 and Article 14, which shall continue in full force and effect) and, without prejudice to the rights of the Parties under Section 11.3, EXCO, Vernon and, if applicable, MLP LLC shall be free immediately to enjoy all rights of ownership of the Assets that would otherwise apply and to sell, transfer, encumber or otherwise dispose of the Assets to any Person without any restriction under this Agreement.

Section 11.3 Remedies Upon Termination.

(a) If EXCO Parent terminates this Agreement (i) under Section 11.1(e), (ii) under Section 11.1(b) in circumstances where EXCO Parent would have had the right to terminate under Section 11.1(e), or (iii) under Section 11.1(g), and, in any such case, as of the date of such termination, all of the conditions to Closing set forth in Section 9.2 have been satisfied or waived as of such date of termination (or, with respect to conditions capable of being satisfied only at Closing, upon an immediate Closing, would be satisfied as of such Closing), then, in any such event, Investor shall pay, or cause to be paid, by wire transfer of immediately available funds to an account or accounts designated by EXCO Parent, within two (2) Business Days after the date on which this Agreement is so terminated, the Termination Fee.

(b) If Investor terminates this Agreement (i) under Section 11.1(d), (ii) under Section 11.1(b) in circumstances where Investor would have had the right to terminate under Section 11.1(d), or (iii) under Section 11.1(h), and, in any such case, as of the date of such termination, all of the conditions to Closing set forth in Section 9.1 have been satisfied or waived as of such date of termination (or, with respect to conditions capable of being satisfied only at Closing, upon an immediate Closing, would be satisfied as of such Closing), then, in any such event, EXCO Parent shall pay, or cause to be paid, by wire transfer of immediately available funds to an account or accounts designated by Investor, within two (2) Business Days after the date on which this Agreement is so terminated, the Termination Fee.

(c) For the avoidance of doubt, neither EXCO Parent nor Investor shall be required to pay the Termination Fee more than once.

Section 11.4 Limitations.

(a) In any circumstance in which a Party has the right to terminate this Agreement and has the right to receive the Termination Fee pursuant to Section 11.3, such Party’s termination of this Agreement and receipt of the Termination Fee shall be the sole and exclusive remedy of such Party and its Affiliates against the other Party or Parties and their respective Affiliates for any loss suffered as a result of any breach of this Agreement (including any willful and material breach), or the failure of the transactions contemplated hereby or thereby to be consummated, or in respect of any oral representation made or alleged to be have been made in connection herewith or therewith, whether in equity or at law, in contract, in tort or otherwise, and upon such termination

and receipt of the Termination Fee, no member of the Investor Group, in the case of any payment of the Termination Fee by or on behalf of Investor, or no member of the EXCO Group, in the case of any payment of the Termination Fee by or on behalf of EXCO Parent, shall have any further liability or obligation, including consequential, indirect or punitive damages, relating to or arising out of any breach of this Agreement (including any willful and material breach), or the failure of the transactions contemplated hereby or thereby to be consummated, or in respect of any oral representation made or alleged to be have been made in connection herewith or therewith, whether in equity or at law, in contract, in tort or otherwise. Prior to Closing, the maximum aggregate monetary liability of either Investor, on the one hand, or EXCO, on the other hand, for any loss suffered as a result of any breach of this Agreement (including any willful and material breach), or the failure of the transactions contemplated hereby or thereby to be consummated, or in respect of any oral representation made or alleged to be have been made in connection herewith or therewith, whether in equity or at law, in contract, in tort or otherwise, shall be limited to the Termination Fee, and in no event shall any Party or Representative or Affiliate thereof seek to recover any money damages (including consequential, indirect or punitive damages) in excess of such amount.

(b) Upon termination of this Agreement, except as expressly set forth above in Section 11.3 and Section 11.4(a), neither Investor Group nor EXCO Group shall have any further liability or obligation relating to or arising out of this Agreement (including any willful and material breach), or the failure of the transactions contemplated hereby or thereby to be consummated, or in respect of any oral representation made or alleged to have been made in connection herewith or therewith, whether in equity or at law, in contract, in tort or otherwise, and in such event, except as expressly set forth above in Section 11.3 and Section 11.4(a), neither Investor Group nor EXCO Group shall seek to recover any money damages (including consequential, indirect, lost profits or punitive damages) or obtain any equitable relief from EXCO Group or Investor Group, as the case may be.

(c) No Investor Group member, except Investor and HGI (but only to the extent expressly set forth herein or in any Related Agreements, to the extent set forth therein, and in the Guarantee), shall have any liability for any obligation or liability of the Parties pursuant to this Agreement or for any claim for any loss suffered as a result of any breach of this Agreement (including any willful and material breach), or the failure of the transactions contemplated hereby or thereby to be consummated, or in respect of any oral representation made or alleged to have been made in connection herewith or therewith, whether in equity or at law, in contract, in tort or otherwise.

(d) No EXCO Group member, except EXCO Parent and EOC (but only to the extent set forth herein or in any Related Agreements to the extent set forth therein), shall have any liability for any obligation or liability of the Parties to this Agreement or for any claim for any loss suffered as a result of any breach of this Agreement (including any willful and material breach), or the failure of the transactions contemplated hereby or thereby to be consummated, or in respect of any oral representation made or alleged to have been made in connection herewith or therewith, whether in equity or at law, in contract, in tort or otherwise.

(e) Each Party acknowledges and agrees that the agreements contained in this Section 11.4 are an integral part of the transactions contemplated hereby, and that without these agreements the Parties would not have entered into this Agreement. Accordingly, if any Party fails promptly to pay the Termination Fee when due pursuant to this Section 11.4 (the “Owing Party”), and, in order to obtain such payment, the other Party commences a suit that results in a judgment against the Owing Party for the Termination Fee, the Owing Party will pay to such other Party, from the date such payment was required to be made, interest at the Default Rate on the Termination Fee. The Parties acknowledge that the Termination Fee shall not constitute a penalty but is liquidated damages, in a reasonable amount that will compensate the respective Parties in the circumstances in which the Termination Fee is payable for their respective efforts and resources expended and opportunities foregone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the transactions contemplated hereby, which amount would otherwise be impossible to calculate with precision.

EXCEPT FOR THE REMEDIES CONTAINED UNDER THE RELATED AGREEMENTS (OTHER THAN THE CLOSING CERTIFICATES) IN SECTION 7.1(D), SECTION 12.2 AND SECTION 13.1, EACH OF THE EXCO PARTIES AND THE INVESTOR (EACH ON THEIR OWN BEHALF AND ON BEHALF OF THE PARTNERSHIP GROUP) RELEASE, REMISE AND FOREVER DISCHARGE THE OTHER PARTIES AND THEIR AFFILIATES AND ALL SUCH PARTIES’ REPRESENTATIVES FROM ANY AND ALL SUITS, LEGAL OR ADMINISTRATIVE PROCEEDINGS, CLAIMS, DEMANDS, DAMAGES, LOSSES, COSTS, LIABILITIES, INTEREST OR CAUSES OF ACTION WHATSOEVER, IN LAW OR IN EQUITY, KNOWN OR UNKNOWN, WHICH SUCH PARTIES MIGHT NOW OR SUBSEQUENTLY MAY HAVE, BASED ON, RELATING TO OR ARISING OUT OF (I) THIS AGREEMENT, (II) EXCO’S OR VERNON’S OWNERSHIP, USE OR OPERATION OF THE ASSETS OR (III) THE CONDITION, QUALITY, STATUS OR NATURE OF THE ASSETS, INCLUDING, IN EACH SUCH CASE, RIGHTS TO CONTRIBUTION UNDER CERCLA OR ANY OTHER ENVIRONMENTAL LAW, BREACHES OF STATUTORY OR IMPLIED WARRANTIES, NUISANCE OR OTHER TORT ACTIONS, RIGHTS TO PUNITIVE DAMAGES AND COMMON LAW RIGHTS OF CONTRIBUTION, RIGHTS UNDER AGREEMENTS BETWEEN ANY EXCO PARTY AND ANY PERSONS WHO ARE AFFILIATES OF SUCH EXCO PARTY, AND RIGHTS UNDER INSURANCE MAINTAINED BY ANY EXCO PARTY OR ANY PERSON WHO IS AN AFFILIATE OF ANY EXCO PARTY, EVEN IF CAUSED IN WHOLE OR IN PART BY THE NEGLIGENCE (WHETHER SOLE, JOINT OR CONCURRENT), STRICT LIABILITY OR OTHER LEGAL FAULT OF ANY RELEASED PERSON.

(e) Any claim for indemnity under this Section 12.2 by any Third Person must be brought and administered by a Party to this Agreement. No Indemnified Person (including any Person within the EXCO Group, the Investor Group or the Partnership Group) other than the Parties shall have any rights against any EXCO Party, MLP LLC or Investor under the terms of this Section 12.2 except as may be exercised on its behalf by MLP LLC, Investor or EXCO, as applicable, pursuant to this Section 12.2. Each Party may elect to exercise or not to exercise indemnification rights under this Section 12.2 on behalf of the other Indemnified Persons affiliated with it in its sole discretion and shall have no liability to any such other Indemnified Person for any action or inaction under this Section 12.2.

Section 12.3 Indemnification Actions. All claims for indemnification under Section 12.2 shall be asserted and resolved as follows:

(a) For purposes hereof, (i) the term “Indemnifying Person” when used in connection with particular Damages shall mean the Person or Persons having an obligation to indemnify another Person or Persons with respect to such Damages pursuant to this Article 12 and (ii) the term “Indemnified Person” when used in connection with particular Damages shall mean the Person or Persons having the right to be indemnified with respect to such Damages by another Person or Persons pursuant to this Article 12.

(b) To make a claim for indemnification under Section 12.2, an Indemnified Person shall notify the Indemnifying Person of its claim under this Section 12.3, including, to the extent known to such Person, the specific details of and specific basis under this Agreement for its claim (the “Claim Notice”). In the event that the claim for indemnification is based upon a claim by a Third Party against the Indemnified Person (a “Third Person Claim”), the Indemnified Person shall provide its Claim Notice promptly after the Indemnified Person has actual knowledge of the Third Person Claim and shall enclose a copy of all papers (if any) served with respect to the Third Person Claim; provided that the failure of any Indemnified Person to give notice of a Third Person Claim as provided in this Section 12.3 shall not relieve the Indemnifying Person of its obligations under Section 12.2 except to the extent such failure materially prejudices the Indemnifying Person’s ability to defend against the Third Person Claim. In the event that the claim for indemnification is based upon an inaccuracy or breach of a representation, warranty, covenant or agreement, the Claim Notice shall specify the representation, warranty, covenant or agreement that was inaccurate or breached.

(c) In the case of a claim for indemnification based upon a Third Person Claim, the Indemnifying Person shall have 30 days from its receipt of the Claim Notice to notify the Indemnified Person whether it admits or denies its obligation to defend the Indemnified Person against such Third Person Claim under this Article 12. If the Indemnifying Person does not notify the Indemnified Person within such 30-day period whether the Indemnifying Person admits or denies its obligation to defend the Indemnified Person, it shall be conclusively deemed to have denied such indemnification obligation hereunder. The Indemnified Person is authorized, prior to and during such 30-day period, to file any motion, answer or other pleading that it shall deem necessary or appropriate to protect its interests or those of the Indemnifying Person and that is not, with respect to the Indemnifying Person’s rights or claims with respect to Third Parties, prejudicial to the Indemnifying Person.

(d) If the Indemnifying Person admits its obligation, it shall have the right and obligation to diligently defend, at its sole cost and expense, the Third Person Claim; provided, that the Indemnifying Person shall not be entitled to control the defense of any Third Person Claim if (i) the Indemnified Person has been advised by counsel that an

actual conflict of interest exists between the Indemnifying Person and the Indemnified Person in connection with the defense of such Third Person Claim, (ii) the Third Person Claim, individually or in the aggregate with any other claim, involves potential Damages that exceed the amount of the indemnification available under this Article 12, (iii) the Third Person Claim seeks injunctive relief or is part of a criminal proceeding or (iv) the Third Person Claim would reasonably be expected to have a material adverse effect on the Indemnified Person’s business or relates to its customers, suppliers, vendors or other service providers; provided, however, in the event that the Indemnifying Person is not entitled to assume exclusive control of the defense, then the Indemnifying Person shall not be bound by any determination resulting from any compromise or settlement effected without its consent (which may not be unreasonably withheld or delayed). If the Indemnifying Person elects to control the defense of a Third Person Claim in accordance with this Section 12.3(d), the Indemnifying Person shall have full control of such defense and proceedings, including any compromise or settlement thereof. If the Indemnifying Person elects to control the defense of a Third Person Claim in accordance with this Section 12.3(d), (x) if requested by the Indemnifying Person, the Indemnified Person agrees to reasonably cooperate (without incurring any out-of-pocket expenses or other material expense) in contesting any Third Person Claim that the Indemnifying Person elects to contest (provided, however, that the Indemnified Person shall not be required to bring any counterclaim or cross-complaint against any Person) and (y) the Indemnified Person may at its own expense participate in, but not control, any defense or settlement of any Third Person Claim controlled by the Indemnifying Person pursuant to this Section 12.3(d). An Indemnifying Person shall not, without the written consent of the Indemnified Person, settle any Third Person Claim or consent to the entry of any judgment with respect thereto which (i) does not result in a final resolution of the Indemnified Person’s liability with respect to the Third Person Claim (including, in the case of a settlement, an unconditional written release of the Indemnified Person), (ii) provides for remedies other than the payment of money damages that are fully indemnified pursuant to this Article 12 or (iii) includes any admission of liability on the part of any Indemnified Person.

(e) If the Indemnifying Person does not elect to, or is not entitled pursuant to Section 12.3(d) to, control the defense of a Third Person Claim, then the Indemnified Person shall have the right to defend against the Third Person Claim (at the sole cost and expense of the Indemnifying Person, if the Indemnified Person is entitled to indemnification hereunder, subject to the other provisions of this Section 12.3), with counsel of the Indemnified Person’s choosing. If the Indemnified Person settles any Third Person Claim over the objection of the Indemnifying Person at a time when the Indemnifying Person either controls, or is entitled to control, the defense of the applicable Third Person Claim, the Indemnified Person shall be deemed to have waived any right to indemnity with respect to such settlement.

(f) In the case of a claim for indemnification not based upon a Third Person Claim, the Indemnifying Person shall have 30 days from its receipt of the Claim Notice to (i) cure the Damages complained of, (ii) admit its obligation to provide indemnification with respect to such Damages or (iii) dispute the claim for such indemnification. If the Indemnifying Person does not notify the Indemnified Person within such 30-day period that it has cured the Damages or that it disputes the claim for such indemnification, the Indemnifying Person shall be deemed to have disputed such claim for indemnification.

Section 12.4 Limitation on Actions.

(a) The representations and warranties of the Parties in Article 5 and Article 6, the corresponding representations and warranties given in the Closing Certificates and the indemnities in Section 12.2 for a breach of such representations or warranties, shall survive the Closing until the later of 12 months following the Closing or the completion of the audit of the financial statements for the fiscal year of the Partnership ending September 30, 2013 (the “Expiration Date”), except that (i) the EXCO Fundamental Representations and the Investor Fundamental Representations (and, in each case, the indemnities for the breach of such representations, warranties and acknowledgements in Section 12.2) shall survive indefinitely, and (ii) the representations and warranties in Section 5.8 (and the indemnities in Section 13.1 for the breach of such representations and warranties) shall survive Closing until the expiration of the applicable statute of limitations (including any applicable extensions).

Subject to Section 12.4(b), the remainder of this Agreement (including the disclaimers in Section 14.14) shall survive the Closing without time limit except (A) as may otherwise be expressly provided herein and (B) for the provisions of Article 13, which shall survive Closing until the expiration of the applicable statute of limitations (including any applicable extensions). Representations, warranties, covenants and agreements shall be of no further force and effect after the date of their expiration, provided that there shall be no termination of any claim asserted pursuant to this Agreement with respect to such a representation, warranty, covenant or agreement prior to its expiration date.

(b) The indemnities in Section 12.2(b)(i), Section 12.2(b)(ii), Section 12.2(c)(i) and Section 12.2(c)(ii) shall terminate as of the termination date of each respective representation, warranty, covenant or agreement that is subject to indemnification thereunder, except in each case as to matters for which a specific written claim for indemnity has been delivered to the Indemnifying Person on or before such termination date. The indemnities in Section 12.2(b)(iv) shall survive the Closing for a period of two years, except in each case as to matters for which a specific written claim for indemnity has been delivered to the Indemnifying Person on or before such termination date. The indemnities in Section 12.2(a) and Section 12.2(b)(iii) shall continue without time limit.

(c) EXCO Parent shall not have any liability for indemnification under Section 12.2(b)(ii) or Section 12.2(b)(iv) or in connection with the breach of any such Section (other than a failure to comply with the final resolution of a claim pursuant to such Section as determined by a final, non-appealable judgment or a settlement agreement) (x) with respect any individual claim (or series of related claims) until the aggregate amount of Damages with respect to such claim (or series of claims) exceeds $75,000 (after which point all such Damages shall, subject to the other limitations of this Section 12.4, be subject to indemnification hereunder) and (y) until and unless the aggregate amount of Damages for which Claim Notices are delivered with respect to Section 12.2(b)(ii) or Section 12.2(b)(iv) exceeds $14,000,000 and then, in the case of this clause (y), only to the extent such Damages exceed such amount.

(d) EXCO Parent shall not have any liability for any indemnification under Section 12.2(b)(ii) or Section 12.2(b)(iv) or in connection with the breach of any such Section (other than a failure to comply with the final resolution of a claim pursuant to such Section as determined by a final, non-appealable judgment or a settlement agreement) for Damages in excess of $70,000,000.

(e) Investor shall not have any liability for indemnification under Section 12.2(c)(ii) or in connection with the breach of such Section (other than a failure to comply with the final resolution of a claim pursuant to such Section as determined by a final, non-appealable judgment or a settlement agreement), (x) with respect any individual claim (or series of related claims) until the aggregate amount of Damages with respect to such claim (or series of claims) exceeds $75,000 (after which point all such Damages shall, subject to the other limitations of this Section 12.4, be subject to indemnification hereunder) and (y) until and unless the aggregate amount of Damages for which Claim Notices are delivered with respect to Section 12.2(c)(ii) exceeds $14,000,000 and then, in the case of this clause (y), only to the extent such Damages exceed such amount.

(f) Investor shall not have any liability for any indemnification under Section 12.2(c)(ii) or in connection with the breach of such Section (other than a failure to comply with the final resolution of a claim pursuant to such Section as determined by a final, non-appealable judgment or a settlement agreement) for Damages in excess of $70,000,000.

(g) For purposes of determining whether there has been a breach of any of Party’s representations and warranties for which another Person is entitled to indemnification under Section 12.2 and the Damages resulting therefrom, any dollar, materiality or Material Adverse Effect qualifiers in such representations or warranties (except for EXCO’s representations and warranties under Section 5.11(a)) shall be disregarded.

(h) The amount of any Damages for which an Indemnified Person is entitled to indemnity under this Article 12 shall be reduced by the amount of insurance proceeds realized by the Indemnified Person or its Affiliates with respect to such Damages (net of any collection costs, and excluding the proceeds of any insurance policy issued or underwritten by the Indemnified Person or its Affiliates), and each Indemnified Person shall use commercially reasonable efforts to claim such insurance coverage with respect to such Damages.

(i) In no event shall any Indemnified Person be entitled to duplicate compensation with respect to the same Damage, liability, loss, cost, expense, claim, award or judgment under more than one provision of this Agreement and the various documents delivered in connection with the Closing. No Indemnified Person shall be entitled to indemnification pursuant to this Article 12 to the extent that such Indemnified Person has been compensated with respect to the applicable Damages by an adjustment pursuant to Section 2.2(a) or Section 2.2(b) or Section 2.3.

(j) Notwithstanding anything herein to the contrary, in the case of any claim for indemnification where Damages have been suffered both by (i) a member of the EXCO Group or Investor or its Affiliates, on the one hand, and (ii) a member of the Partnership Group, on the other hand, to the extent the Indemnified Party can be made whole by the satisfaction of the indemnification claim of a member of the Partnership Group, the indemnification claim of such member of the Partnership Group shall be satisfied first.

(a) EXCO shall be liable for a proportionate share of the actual amount of such Property Taxes for the Current Tax Period determined by multiplying such amount by a fraction, the numerator of which is the number of days in the Current Tax Period prior to the Effective Time and the denominator of which is the total number of days in the Current Tax Period and the Partnership and MLP LLC shall be liable for a proportionate share of the actual amount of such Property Taxes for the Current Tax Period determined by multiplying such amount by a fraction, the numerator of which is the number of days (including the Closing Date) in the Current Tax Period on and after the Effective Time and the denominator of which is the total number of days in the Current Tax Period.

(b) In the case of Production Taxes for the Current Tax Period, EXCO shall be liable for a portion of such Taxes allocated based on the number of units or value of production actually produced and sold, as applicable, before the Effective Time and the Partnership and MLP LLC shall be liable for a portion of such Taxes allocated based on the number of units or value of production actually produced and sold, as applicable, at or after the Effective Time.

(c) In the case of any Sales/Use Taxes for the Current Tax Period, EXCO shall be liable for its share of any such Sales/Use Taxes imposed on the owner of the Assets as a result of any transaction occurring before the Effective Time. The Partnership and MLP LLC shall be liable for their share of any such Sales/Use Taxes imposed on the owner of the Assets as a result of any transaction occurring on or after the Effective Time.

(d) If EXCO or MLP LLC makes any payment of Property Taxes, Production Taxes or Sales/Use Taxes for which the other Party is liable pursuant to this Section 13.3, then to the extent that the Cash Consideration has not been adjusted pursuant to Section 2.1(a) or payments made pursuant to Section 8.3 to account for such payment, the applicable Party shall reimburse the other Party promptly but in no event later than ten days after the presentation of a statement setting forth the amount of reimbursement to which the presenting Party is entitled along with such supporting evidence as is reasonably necessary to calculate the amount of the reimbursement.

Section 13.4 Tax Refunds and Recoupments. Notwithstanding anything to the contrary (including Section 8.3), to the extent that the Partnership or MLP LLC receives any Tax refund or credit with respect to any Taxes for which EXCO is liable pursuant to this Agreement, or any recoupment of Taxes for any Tax periods or portions thereof ending on or before the Effective Time paid by EXCO or its Affiliates on behalf of other Working Interest owners, royalty interest owners, overriding royalty interest owners and other interests owners in such Production Assets that have not been recouped by EXCO before the Closing Date, the Partnership or MLP LLC shall promptly but in no event later than ten days after receipt of such refund, credit or recoupment, as applicable, pay such amount (net of any expenses incurred by the Partnership or Partnership Subsidiaries in obtaining such Tax Refund) to EXCO to the extent the Cash Contribution has not been increased pursuant to Section 2.1(a) on account thereof.

Section 13.5 Tax Cooperation. Each of EXCO, Investor, and the Partnership agree to furnish or cause to be furnished to the other, upon request, as promptly as practicable, such information and assistance relating to Taxes, including, without limitation, access to books and records, as is reasonably necessary for the filing of all Tax Returns by any such Party, the making of any election relating to Taxes, the preparation for any audit by any taxing authority and the prosecution or defense of any claim, suit or proceeding relating to any Tax.

Section 13.6 Characterization of Certain Payments. The Parties agree that any payments made pursuant to this Article 13, Article 12, Section 8.3 or Article 14 shall be treated for all Tax purposes as an adjustment to the Cash Contribution unless otherwise required by Law.

Section 13.7 Tax Treatment of the Transactions. The Parties intend and expect that the transactions contemplated by this Agreement, taken together, will be treated, for purposes of federal income taxation and for purposes of certain state income tax laws that incorporate or follow federal income tax principles (“Tax Purposes”), as resulting in the creation of a partnership in which EXCO and Investor are treated as partners. Accordingly, for Tax Purposes: (a) EXCO will be treated as contributing to the Partnership at Closing all of its interests in the Assets in exchange for an interest in the Partnership; (b) Investor will be treated as contributing to the Partnership at Closing the Cash Contribution (as adjusted) in exchange for an interest in the Partnership; and (c) EXCO will be treated as receiving a distribution from the Partnership at Closing: (i) first out of the proceeds of the Credit Agreement as a debt-finance transfer within the meaning of Treasury Regulations Section 1.707-5(b)(1) to the extent of EXCO’s allocable share of the indebtedness incurred under the Credit Agreement under Treasury Regulations Sections 1.707-5(a)(2), 1.707-5(b)(2) and 1.752-3(a)(3); (ii) to the extent the amount distributed to EXCO exceeds EXCO’s allocable share of the indebtedness incurred under the Credit Agreement as described in clause (i), as a reimbursement of EXCO’s preformation expenditures with respect to the Assets within the meaning of Treasury Regulations Section 1.707-4(d), to the extent applicable; and (iii) to the extent the amount distributed exceeds the amounts described in clauses (i) and (ii), in a transaction subject to treatment under Section 707(a)-(2)(B) of the Code and its implementing Treasury Regulations as in part a sale, and in part a contribution, of its interests in the Assets to the Partnership to the extent that Treasury Regulations Sections 1.707-4(d) and 1.707-5(b)(1) are inapplicable. The Parties shall file all Tax Returns in a manner consistent with this intended Tax treatment.

Section 13.8 Allocations for Tax Purposes. EXCO and Investor agree that to the extent the amount distributed by the Partnership to EXCO is treated for federal tax purposes as consideration for a sale of EXCO’s interests in the Assets pursuant to Section 707(a)(2)(B) of the Code (collectively, the “Allocable Amount”), such amount shall be allocated among the Assets treated as sold to the Partnership for federal and state income tax purposes. The initial draft of such allocations shall be prepared by EXCO and shall be provided to Investor as soon as practicable following the determination of the Cash Contribution pursuant to Section 2.1(a). EXCO and Investor shall then cooperate to prepare a final schedule (the “Allocation Schedule”) of the allocation of Allocable Amount among such Assets in accordance with Section 1060 of the Code and the Treasury regulations promulgated thereunder (and any similar provision of state, local or foreign law, as appropriate). The Allocation Schedule shall be updated to reflect any adjustments to the Allocable Amount. EXCO and Investor shall work in good faith to resolve any disputes relating to the Allocation Schedule. If EXCO and Investor are unable to resolve any dispute regarding the Allocation Schedule within thirty days, such dispute shall be resolved by a nationally recognized accounting firm acceptable to EXCO and Investor, the costs of which shall be borne equally by EXCO and Investor. EXCO and Investor shall file all Tax Returns (including, but not limited to, IRS Form 8594) consistent with the Allocation Schedule. Neither EXCO nor Investor shall take any Tax position inconsistent with such Allocation Schedule, and neither EXCO nor Investor shall agree to any proposed adjustment to the Allocation Schedule by any Taxing authority without first giving the other Party prior written notice; provided, however, that nothing contained herein shall prevent EXCO or Investor from settling any proposed deficiency or adjustment by any Taxing authority based upon or arising out of the Allocation Schedule, and neither EXCO nor Investor shall be required to litigate before any court any proposed deficiency or adjustment by any Taxing authority challenging such Allocation Schedule.

Prior to Closing, if pursuant to Article 3, Article 4 or Section 7.4, an adjustment is to be made to the Transaction Items based upon (x) an agreed upon Title Defect Amount or Remedy Amount or (y) the Allocated Value of an Asset to be excluded pursuant to Article 3, Article 4 or Section 7.4, other than an asset excluded pursuant to Section 3.6(b), Section 3.6(e) or Section 3.7(b) that is subject to potential post-Closing contribution to the Partnership pursuant to Section 3.6(c), Section 3.6(e) or Section 3.7(b) (such amount pursuant to clause (x) or (y), as applicable, the “Agreed Reduction Amount”), then:

IV.	Disputed Remedy Amounts.

Prior to Closing, if, pursuant to Section 4.2(a) or Section 4.2(c)(i), an adjustment is to be made to the Transaction Items based upon an amount equaling the average of the Parties’ Remedy Amounts with respect to any Environmental Defect (such average, the “Averaged Remedy Amount”), then:

(i) the Target Cash Contribution will be reduced by 51.4% of such Averaged Remedy Amount and (ii) the Target Investor Units will be reduced by the quotient of (A) the amount of the reduction in clause (i) divided by (B) $10;

ii.

the Target Initial Draw Amount will not be reduced;

iii.

(i) the Target Distribution Amount will be reduced by 82.4% of such Averaged Remedy Amount and (ii) the Target EXCO Units will be reduced by the quotient of (A) the product of (x) such Averaged Remedy Amount multiplied by (y) 17.6% divided by (B) $10;

Annex A - 3

iv.
