 EOC has formed TGGT Holdings, LLC, a Delaware limited liability company (the “Company”) and at
Closing EOC desires to contribute the membership interests of GP Holding and the limited partner interests in each of TGG and Talco to the Company on the terms and conditions hereinafter set forth. 
 BG desires to contribute a specified amount of cash to the Company on the terms and conditions hereinafter set forth and the Company desires to issue to
BG a fifty percent (50%) membership interest in the Company on the terms and conditions hereinafter set forth.

 3.5 Final Settlement Statement. A final settlement statement (the
“Final Settlement Statement”) will be prepared by EXCO, based on actual income and expenses during the Interim Period and which takes into account all final adjustments made to the Closing Cash Contribution and shows the resulting
final Closing Cash Contribution (the “Final Cash Amount”), and is delivered to BG on or before 120 days after Closing. The Final Settlement Statement shall set forth the actual proration of the amounts required by this Agreement.
EXCO shall, at BG’s request, supply all reasonable documentation in its or its Affiliates’ possession available to support the actual revenue, expenses and other items for which adjustments are made. As soon as practicable, and in any
event within 45 days after receipt of the Final Settlement Statement, BG shall return a written report containing any proposed changes to the Final Settlement Statement and an explanation of any such changes and the reasons therefor (the
“Dispute Notice”). If the Final Cash Amount set forth in the Final Settlement Statement is mutually agreed upon by EXCO and BG, the Final Settlement Statement and the Final Cash Amount, shall be final and binding on the Parties.

 3.6 Disputes. If EXCO and BG are unable to resolve the matters addressed in the Dispute Notice, each of BG and
EXCO shall within 14 Business Days after the delivery of such Dispute Notice, summarize its position with regard to such dispute in a written document and submit such summaries to Ernst & Young LLP in Dallas, Texas, or such other Person as
may be selected pursuant to this Section (the “Accounting Arbitrator”), together with the Dispute Notice, the Final Settlement Statement and any other documentation such Party may desire to submit. The Accounting Arbitrator shall
also be furnished with a copy of this Agreement. Should Ernst & Young LLP fail or refuse to agree to serve as Accounting Arbitrator within 20 days after receipt of a written request from any Party to serve, the Parties shall request
Deloitte & Touche LLP to serve as Accounting Arbitrator. Should Deloitte & Touche LLP fail or refuse to agree to serve as Accounting Arbitrator within 20 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 10 days after the end of that 20 day period, or should no replacement Accounting Arbitrator agree to serve within 60 days after the original written request
pursuant to this Section, the Accounting Arbitrator shall be appointed by the Dallas office of the American Arbitration Association. Within 20 Business Days after receiving the Parties’ respective submissions, the Accounting Arbitrator shall
render a decision choosing either EXCO’s position or BG’s position with respect to each matter addressed in any Dispute Notice, whichever is most accurate based on the terms of this Agreement and the materials described above. Any decision
rendered by the Accounting Arbitrator pursuant hereto shall be final, conclusive and binding on EXCO and BG and will be enforceable against any of the Parties in any court of competent jurisdiction. The Accounting Arbitrator shall act as an expert
for the limited purpose of determining the specific disputed aspects of the Final Settlement Statement submitted by any Party and may not award damages, interest, or penalties to any Party with respect to any matter. The costs of such Accounting
Arbitrator shall be borne one-half by BG and one-half by EXCO. 
 3.7 Adjustment for Final Settlement Statement.
Subject to adjustments for revenues and expenses paid by the Parties pursuant to Section 2.4(b) and 2.4(c), any difference in the Adjusted Closing Cash Contribution as paid at Closing pursuant to the Preliminary Settlement
Statement and the Final Cash Amount as determined pursuant to Section 3.5 and, if applicable, Section 3.6, shall, if the Adjusted Closing Cash Consideration exceeds the Final Cash Amount, be contributed to the Company by EXCO
or, if the Adjusted Closing Cash Consideration is less than the Final Cash Amount, be contributed to the Company by BG, in each case together with interest from the Closing Date to the date of payment at a rate equal to the one month London 

  

 8 








 
Inter-Bank Offer Rate (as published in the Wall Street Journal) plus an additional 2.5 percentage points (or, if such rate is contrary to any applicable
usury Law, the maximum rate permitted by such applicable Law), within 10 days of final determination hereunder and the Parties shall cause the Company to promptly make a distribution of such amount to the other Party. All amounts paid pursuant to
this Section 3.7 shall be delivered in United States currency by wire transfer of immediately available funds to the account specified in writing by the relevant Party. 
 3.8 Allocation for Imbalances at Closing. If, prior to Closing, BG or EXCO discovers an error in the Imbalances set forth in
Schedule 4.12, then the Closing Cash Contribution shall be further adjusted at Closing pursuant to Section 3.2(a)(iv) or Section 3.2(b)(v), as applicable, and Schedule 4.12 will be deemed amended
immediately prior to the Closing to reflect the Imbalances for which the Closing Cash Contribution is so adjusted. 
 3.9
Maintenance of Value. 
 (a) EXCO shall receive at Closing pursuant to the special distribution
described in Section 4.5(e) of the Limited Liability Company Agreement in excess of $200 million from the Adjusted Closing Cash Contribution. EOC agrees that until December 31, 2011, it will maintain a minimum of $200 million of such
consideration (the “Minimum Consideration”) in EOC and shall not dividend or otherwise distribute any of such Minimum Consideration to any of EOC’s Affiliates, or use any of such Minimum Consideration to repay debt to any of
EOC’s Affiliates or to satisfy any obligation on behalf of any of EOC’s Affiliates, other than (in each case) EOC’s own direct or indirect wholly-owned subsidiaries; provided, however, EOC may use all or any portion of such Minimum
Consideration to (i) pay expenses or costs in connection with EOC’s general corporate purposes, (ii) keep such amounts as cash or cash equivalents and make other short-term investments of such amounts, (iii) acquire properties or
other assets, (iv) make capital expenditures, including the payment of any costs of New Business or Acquired Business (as each such term is defined in the Limited Liability Company Agreement), (v) make capital contributions to the Company,
(vi) satisfy the debt described in clause (a) of the definition of “EXCO Debt Instruments” by making a payment to reduce the outstanding principal and interest thereunder to the extent such payment is made because of a mandatory
reduction of the borrowing base under such EXCO Debt Instrument in connection with the contribution of the Contributed Interests to the Company as part of the transactions contemplated by this Agreement and (vii) satisfy the debt described in
clause (b) of the definition of “EXCO Debt Instruments” by paying off the outstanding principal and interest under such EXCO Debt Instrument and all of such uses shall be considered maintenance of such consideration in EOC as required
pursuant to foregoing. To the extent that EOC or its direct or indirect wholly-owned subsidiaries uses all or any portion of such Minimum Consideration for the purposes set forth in clause (i), (iii), (iv), (v) (vi) or (vii),
the amount required to be maintained by EOC as Minimum Consideration shall be decreased by the amount of such usage, and, in the event the amount required to be maintained by EOC as Minimum Consideration is reduced to zero, then this
Section 3.9(a) shall thereafter terminate and be of no further force and effect, subject, however, to Section 3.9(b). 
 (b) Notwithstanding Section 3.9(a), should a portion of the consideration be used to pay off amounts owing pursuant to the EXCO Debt Instruments and (i) the payment does not satisfy the requirements
of Section 3.9(a)(vi) or (vii), then additional amounts thereafter 

  

 9 








 
borrowed under such EXCO Debt Instruments, up to the amount previously repaid that did not satisfy the requirements of Section 3.9(a)(vi) or
(vii), shall again be subject to the restrictions in Section 3.9(a) or (ii) the debt represented in the EXCO Debt Instruments be consolidated with other debt from any of EOC’s Affiliates (other than its own direct or
indirect wholly-owed subsidiaries) or be replaced by a new credit arrangement providing for indebtedness of both EOC and one or more of its Affiliates (other than its own direct or indirect wholly-owed subsidiaries), EOC shall provide BG and the
Company with a payment guarantee of EOC’s obligations for additional contributions under Article 3 of the Limited Liability Company Agreement from EOC’s ultimate parent entity (presently EXCO Resources, Inc.) in a form substantially
similar to the BG Parent Guaranty Agreement, provided that such guaranty shall terminate at the same time that the Joint Development Agreement (as that term is defined in the Purchase and Sale Agreement) terminates, and the restrictions on use of
consideration in Section 3.9(a) shall thereafter terminate and be of no further effect. If BG in the future enters into any agreement for borrowed money or security arrangements that are in whole or in part for the benefit of BG’s
Affiliates (other than its own direct or indirect wholly-owed subsidiaries) as borrowers, BG shall provide EOC and the Company with a payment guarantee of BG’s obligations for additional contributions under Article 3 of the Limited Liability
Company Agreement from BG’s ultimate parent entity (for this purpose, presently BG Energy Holdings Limited) in a form substantially similar to the BG Parent Guaranty Agreement, provided that such guaranty shall terminate at the same time that
the Joint Development Agreement (as that term is defined in the Purchase and Sale Agreement) terminates.

 ARTICLE 10 
 ACCESS / DISCLAIMERS 
 10.1 Access. 
 (a) From and after the date hereof and up to and including the Closing Date (or earlier termination of this Agreement) but subject to the
other provisions of this Section 10.1 and obtaining any required consents of Third Parties, (with respect to which consents EXCO shall use commercially reasonable efforts to obtain) EXCO shall afford to BG and its officers, employees,
agents, accountants, attorneys, investment bankers, consultants and other authorized representatives (“BG’s Representatives”) full access, during normal business hours, to the Subject Assets and all Records and other documents
in EXCO’s or any of their respective Affiliates’ possession relating primarily to the Contributed Interests or Subject Assets. EXCO shall also make available to BG and BG’s Representatives, upon reasonable notice during normal
business hours, EXCO’s personnel knowledgeable with respect to the Subject Assets in order that BG may make such diligence investigation as BG considers necessary or appropriate. All investigations and due diligence conducted by BG or any
BG’s Representative shall be conducted at BG’s sole cost, risk and expense and any conclusions made from any examination done by BG or any BG’s Representative shall result from BG’s own independent review and judgment. BG shall
coordinate its access rights and physical inspections of the Subject Assets with EXCO to reasonably minimize any inconvenience to or interruption of the conduct of business by EXCO. BG shall, and shall cause all BG’s Representatives to, abide
by EXCO’s safety rules, regulations, and operating policies of which they are informed while conducting its due diligence evaluation of the Subject Assets including any environmental or other inspection or assessment of the Subject Assets.

 (b) Before conducting any sampling, boring, drilling or other invasive investigation activities (“Invasive
Activities”) on or with respect to any of the Subject Assets, BG shall furnish EXCO with a written description of the proposed scope of the Invasive Activities to be conducted, including a description of the activities to be conducted and a
description of the approximate location and expected timing of such activities. If any of the proposed Invasive Activities may unreasonably interfere with normal operation of the Subject Assets, EXCO may request an appropriate modification of the
proposed Invasive Activity. Any Invasive Activities shall be conducted by a reputable environmental consulting or engineering firm, approved in advance by EXCO (such approval not to be unreasonably withheld or delayed) and, once approved, such
environmental consulting or engineering firm shall be deemed to be a “BG’s Representative.” EXCO hereby approves ERM NA Holdings Corp., ERM Group Holdings Limited and any Affiliate thereof as an environmental consulting firm that may
conduct such Invasive Activities and such environmental consulting firm is hereby deemed to be a “BG’s Representative.” EXCO shall have the right, at its option and expense, to split any samples collected from the Subject Assets with
BG 
 (c) BG hereby defends, indemnifies and holds harmless each of EXCO Indemnified Parties from and against any and all
Liabilities attributable to personal injury, death or physical property damage, or violation of EXCO’s or its Affiliate’s rules, regulations or operating policies of which BG or the BG’s Representative associated with the Liabilities
had been informed arising out of, resulting from or relating to any field visit, environmental property

assessment, or other due diligence activity conducted by BG or any BG’s Representative with respect to the Assets, EVEN IF SUCH LIABILITIES ARISE OUT
OF OR RESULT FROM, SOLELY OR IN PART, THE SOLE, ACTIVE, PASSIVE, CONCURRENT OR COMPARATIVE NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT OR VIOLATION OF LAW OF OR BY A MEMBER OF EXCO INDEMNIFIED PARTIES, EXCEPTING ONLY LIABILITIES ACTUALLY RESULTING
ON THE ACCOUNT OF THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF A MEMBER OF EXCO INDEMNIFIED PARTIES. 
 (d) BG agrees to
review the report prepared by Environmental Resource Management Southwest, Inc. with respect to certain of the Assets and to disclose to EXCO such portions thereof as BG deems reasonably appropriate to support any claims for Environmental Defects,
or otherwise deems reasonably appropriate, and which BG does not believe in good faith need to remain privileged. Neither BG by its delivery of said documents nor EXCO by its receipt of said documents or otherwise shall be deemed to have made any
representation or warranty, expressed, implied or statutory, as to the condition to the Subject Assets or to the accuracy of said documents or the information contained therein. 
 (e) Upon completion of BG’s due diligence, BG shall at its sole cost and expense and without any cost or expense to EXCO or its
Affiliates, (i) repair all physical damage done to the Subject Assets in connection with BG’s due diligence, (ii) restore the Subject Assets to the approximate same or better physical condition than it was prior to commencement of
BG’s due diligence and (iii) remove all equipment, tools or other property brought onto the Subject Assets in connection with BG’s due diligence. Any disturbance to the Subject Assets (including the real property associated with such
Subject Assets) resulting from BG’s due diligence will be promptly corrected by BG. 
 10.2 Confidentiality. BG
acknowledges that, pursuant to its right of access to the Records or the Subject Assets, BG will become privy to confidential and other information of EXCO and that such confidential information shall be held confidential by BG and BG’s
Representatives in accordance with the terms of the Confidentiality Agreement. If the Closing should occur, the foregoing confidentiality restriction on BG, including the Confidentiality Agreement, shall terminate (except as to (a) any Subject
Assets that are excluded from the transactions contemplated hereby pursuant to the provisions of this Agreement, and (b) the Excluded Assets).

AGREEMENT OR THE CERTIFICATES OF EXCO TO BE DELIVERED AT CLOSING PURSUANT TO SECTION 9.3(g), (I) EXCO MAKES NO REPRESENTATIONS OR WARRANTIES, EXPRESS, STATUTORY OR IMPLIED, AND (II) EXCO EXPRESSLY DISCLAIMS ALL LIABILITY AND

 (b) EXCEPT AS EXPRESSLY SET FORTH IN ARTICLE 4 OF THIS AGREEMENT OR THE
CERTIFICATES OF EXCO TO BE DELIVERED AT CLOSING PURSUANT TO SECTION 9.3(g), AND WITHOUT LIMITING THE GENERALITY OF THE FOREGOING, EXCO EXPRESSLY DISCLAIMS ANY REPRESENTATION OR WARRANTY, EXPRESS, STATUTORY OR IMPLIED, AS TO (I) TITLE TO

AGREEMENT OR ANY DISCUSSION OR PRESENTATION RELATING THERETO, AND (VI) ANY IMPLIED OR EXPRESS WARRANTY OF FREEDOM FROM PATENT OR TRADEMARK INFRINGEMENT. EXCEPT AS EXPRESSLY REPRESENTED OTHERWISE IN ARTICLE 4 OF THIS AGREEMENT OR THE
CERTIFICATES OF EXCO TO BE DELIVERED AT CLOSING PURSUANT TO SECTION 9.3(g), EXCO FURTHER DISCLAIMS ANY REPRESENTATION OR WARRANTY, EXPRESS, STATUTORY OR IMPLIED, OF MERCHANTABILITY, FREEDOM FROM LATENT VICES OR DEFECTS, FITNESS FOR A
PARTICULAR PURPOSE OR CONFORMITY TO MODELS OR SAMPLES OF MATERIALS OF ANY SUBJECT ASSETS, RIGHTS OF A PURCHASER UNDER APPROPRIATE STATUTES TO CLAIM DIMINUTION OF CONSIDERATION OR RETURN OF THE PURCHASE PRICE OR CONSIDERATION, IT BEING EXPRESSLY

(KNOWN OR UNKNOWN, LATENT, DISCOVERABLE OR UNDISCOVERABLE), AND THAT BG HAS MADE OR CAUSED TO BE MADE SUCH INSPECTIONS AS BG DEEMS APPROPRIATE. 
 (c) OTHER THAN THOSE REPRESENTATIONS SET FORTH IN SECTION 4.14 AND AS REPEATED IN THE CERTIFICATES OF EXCO TO BE DELIVERED AT CLOSING PURSUANT TO SECTION 9.3(g), EXCO HAS NOT AND WILL NOT MAKE ANY
REPRESENTATION OR WARRANTY REGARDING ANY MATTER OR CIRCUMSTANCE RELATING TO ENVIRONMENTAL LAWS, THE RELEASE OF MATERIALS INTO THE ENVIRONMENT OR THE PROTECTION OF HUMAN HEALTH, SAFETY, NATURAL RESOURCES OR THE ENVIRONMENT, OR ANY OTHER ENVIRONMENTAL

SUBJECT ASSETS IN AN “AS IS” AND “WHERE IS” CONDITION WITH ALL FAULTS FOR PURPOSES OF THEIR ENVIRONMENTAL CONDITION AND THAT BG HAS MADE OR CAUSED TO BE MADE SUCH ENVIRONMENTAL INSPECTIONS AS BG DEEMS APPROPRIATE. 
 (d) The Parties agree that, to the extent required by applicable law to be effective, the disclaimers of certain representations and
warranties contained in this Section 10.3 are “conspicuous” disclaimers for the purpose of any applicable Law. 
 ARTICLE 11 
 CASUALTIES; TRANSFER RESTRICTIONS 
 11.1 Intentionally Omitted. 
 11.2 Intentionally Omitted. 
 11.3 Casualty or Condemnation Loss.

 (a) Notwithstanding anything herein to the contrary, from and after the Effective Time if Closing occurs, with respect to
the Subject Assets, the Contributed Companies shall bear all risk of loss with respect to the depreciation of personal property due to ordinary wear and tear and neither BG nor any Contributed Company shall assert such matters as any casualty losses
or Title Defects hereunder. 
 (b) If, after the date of this Agreement but prior to the Closing Date, any portion of the
Subject Assets is damaged or destroyed by fire or other casualty or is taken in condemnation or under right of eminent domain, then BG shall not as a result be excused from Closing and EXCO shall elect by written notice to BG prior to Closing either
(i) to cause the Subject Assets affected by such casualty or taking to be repaired or restored to at least its condition prior to such casualty or taking, at EXCO’s sole cost, as promptly as reasonably practicable (which work may extend
after the Closing Date) or (ii) to indemnify BG and the Contributed Companies through a document to be delivered at Closing reasonably acceptable to EXCO and BG against any costs or expenses that BG and the Contributed Companies reasonably
incur to repair or restore any Subject Assets affected by such casualty or taking. In each case, EXCO shall be entitled to all rights to insurance, condemnation awards and other claims against Third Parties with respect to the casualty or taking
except to the extent the Parties otherwise agree in writing. 
 (c) If any action for condemnation or taking under right of
eminent domain is pending or threatened with respect to any Subject Asset or portion thereof after the date of this Agreement, but no taking of such Subject Asset or portion thereof occurs prior to the Closing Date, BG shall nevertheless be required
to close and EXCO, at Closing, shall assign, transfer and set over to the Midstream Companies or subrogate the Midstream Companies to all of EXCO’s right, title and interest (if any) in such condemnation or eminent domain action, including any
future awards therein, to the extent (and only to the extent) attributable to the Subject Assets threatened to be taken, except that EXCO shall reserve and retain (and the Midstream Companies shall assign to EXCO) all rights, titles, interests and
claims against Third Parties for the recovery of EXCO’s costs and expenses incurred prior to the Closing in defending or asserting rights in such action with respect to the Subject Assets. 
  

 32 








 11.4 Preferential Purchase Rights and Consents to Assign. 
 (a) With respect to any preferential purchase right pertaining to a Subject Asset and the transactions contemplated hereby, EXCO, within
10 days after the date of this Agreement, shall send to the holder of each such right a notice, in material compliance with the contractual provisions applicable to such right requesting a waiver of such right. In addition, EXCO, within 10 days
after the date of this Agreement, shall send to each holder of a right to consent to assignment pertaining to the Subject Assets and the transactions contemplated hereby a notice seeking such holder’s consent to the transaction contemplated
hereby. Any preferential purchase right must be exercised subject to all terms and conditions set forth in this Agreement, including the successful closing of this Agreement pursuant to Article 9. The consideration payable under this
Agreement for any particular Subject Asset for purposes of preferential purchase right notices shall be the reasonably allocated value of such Subject Asset. EXCO shall use commercially reasonable efforts to cause such waivers of preferential
purchase rights (or exercise thereof) and consents to assignment to be obtained and delivered prior to Closing, provided that EXCO 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 waivers and consents. 
 (b) If, prior to the Closing, any holder of a preferential purchase
right notifies EXCO that it intends to consummate the purchase of the Subject Asset to which its preferential purchase right applies, then the Closing Cash Contribution shall be reduced by 50% of the reasonably allocated value of the relevant
Subject Asset (and such Subject Asset shall no longer be considered subject to this Agreement for purposes of the other adjustments in Section 3,2). The Midstream Companies shall be entitled to all proceeds paid by a Person exercising a
preferential purchase right prior to the Closing and, for the avoidance of doubt, shall be entitled to distribute all such proceeds to EOC immediately prior to Closing. If the Closing occurs and (i) any holder of a preferential purchase right
has notified EXCO that it intends to consummate the purchase of the Subject Asset to which its preferential purchase right applies, but the consummation thereof has not occurred or (ii) the time for exercising a preferential purchase right has
not then expired, then the Closing Cash Contribution shall not be reduced at Closing and, if the holder of the applicable preferential purchase right thereafter consummates the purchase of the Subject Asset covered by such right, then the Closing
Cash Contribution shall be reduced in the final settlement pursuant to Section 3.5 or Section 3.6 by an amount equal to 50% of the reasonably allocated value of the relevant Subject Asset (and such Subject Asset shall no
longer be considered subject to this Agreement for purposes of the other adjustments in Section 3,2), and the proceeds paid by the Person exercising the preferential purchase right shall be distributed to EOC. 
 (c) If (i) EXCO fails to obtain a required consent prior to the Closing and the failure to obtain such consent would cause
(A) the rights of the applicable Midstream Company with respect to the Subject Asset affected thereby to be void or (B) the termination of a Right-of-Way under the express terms thereof or (ii) a consent requested by EXCO is denied in
writing and in either case, (iii) the consent is not a consent of a Governmental Authority or a material 

  

 33 








 
consent required from any other Person as a condition to Closing under Section 7.6, or BG has waived in writing the requirement with respect to
such consent under Section 7.6, then if permitted within the terms of such consent requirement, the applicable Midstream Company will transfer that portion of such Subject Asset to another Affiliate of EXCO, and the Closing Cash
Contribution shall be reduced by 50% of the reasonably allocated value of that portion of such Subject Asset, and, if such Subject Asset is necessary for the operation of the Systems, the Parties shall negotiate in good faith a commercially
reasonable basis on which the applicable Midstream Company may continue to use such Subject Asset. In the event that a required consent (with respect to a Subject Asset excluded pursuant to this Section 11.4(c)) that was not obtained
prior to Closing is obtained following Closing then within 10 days after such consent is obtained, EXCO shall cause such Subject Interest to be conveyed to the applicable Midstream Company, BG shall contribute to the Company the amount by which the
Closing Cash Contribution was reduced with respect to such Subject Asset or portion thereof and EXCO and BG shall cause the Company to make a special distribution to EXCO in an amount equal to BG’s contribution. 
 (d) If (i) EXCO fails to obtain a required consent prior to the Closing and the failure to obtain such consent would not cause
(A) the rights of the applicable Midstream Company with respect to the Subject Asset affected thereby to be void or (B) the termination of a Right-of-Way under the express terms thereof, and (ii) the consent is not denied in writing
and (iii) the consent is not a consent of a Governmental Authority or a material consent required from any other Person as a condition to Closing under Section 7.6, or BG has waived in writing the requirement with respect to such
consent under Section 7.6, then the portion of the Subject Asset subject to such failed consent shall remain in the applicable Midstream Company as part of the Subject Assets and BG and the Contributed Companies shall have no claim
against, and EXCO shall have no Liability for, the failure to obtain such consent; provided that if the affected Subject Asset subject to such requirement is a Right-of-Way, then BG may elect prior to Closing to treat the unsatisfied consent
requirement affecting such Right-of-Way as a breach of Section 4.29. 
 ARTICLE 12 
 ENVIRONMENTAL MATTERS 
 12.1
Environmental Defects. 
 (a) Assertions of Environmental Defects. BG must deliver claim notices to EXCO
meeting the requirements of this Section 12.1(a) (collectively the “Environmental Defect Notices” and individually an “Environmental Defect Notice”) not later than the Defect Claim Date setting forth any
matters which, in BG’s reasonable opinion, constitute Environmental Defects and which BG intends to assert as Environmental Defects pursuant to this Section 12.1. For all purposes of this Agreement but subject to BG’s remedy
for a breach of EXCO’s representation contained in Section 4.14 and BG’s rights under Section 13.2, BG and the Contributed Companies shall be deemed to have waived any Environmental Defect which BG fails to assert
as an Environmental Defect by an Environmental Defect Notice received by EXCO on or before the Defect Claim Date. To be effective, each Environmental Defect Notice shall be in writing and shall include (i) a description of the matter
constituting the alleged Environmental Defect, (ii) a description of each Asset (or portion thereof) that is affected by the alleged 

  

 34 








 
Environmental Defect, (iii) supporting documents available to BG reasonably necessary for EXCO to verify the existence of the alleged Environmental
Defect, and (iv) a calculation of the Remediation Amount (itemized in reasonable detail) that BG asserts is attributable to such alleged Environmental Defect. BG’s calculation of the Remediation Amount included in the Environmental Defect
Notice must describe in reasonable detail the Remediation proposed for the Environmental Condition that gives rise to the asserted Environmental Defect and identify all assumptions used by BG in calculating the Remediation Amount, including the
standards that BG asserts must be met to comply with Environmental Laws. EXCO shall have the right, but not the obligation, to cure any claimed Environmental Defect on or before Closing. 
 (b) Remedies for Environmental Defects. In the event that any Environmental Defect timely asserted by BG in accordance with
Section 12.1(a) is not waived in writing by BG or cured on or before Closing, then, subject to EXCO’s continuing right to dispute the existence of a Environmental Defect and/or the Remediation Amount asserted with respect thereto,
the Parties shall mutually elect to: 
 (i) subject to the Individual Environmental Threshold and the Environmental
Deductible, reduce the Closing Cash Contribution by the Remediation Amount; 
 (ii) to the extent attributable to the Subject
Assets, have EXCO assume responsibility for the Remediation of such Environmental Defect and indemnify and hold harmless the BG Indemnified Parties and the Contributed Companies from and against all Liabilities associated with such Environmental
Defect and Remediation in an indemnity in form and substance satisfactory to BG; 
 (iii) have the applicable Midstream
Company assign the entirety of the Subject Asset that is subject to such Environmental Defect, together with all associated Subject Assets, to EXCO in which event the Closing Cash Contribution shall be reduced by an amount equal to the reasonably
allocated value of the affected Subject Asset; or 
 (iv) to the extent attributable to the Subject Assets, have EXCO
indemnify and hold harmless the BG Indemnified Parties and the Contributed Companies from and against all Liabilities associated with such Environmental Defect by an indemnity in form and substance reasonably satisfactory to BG. 
 In the event the Parties do not agree in writing by Closing on an election of alternative (i), (ii), (iii) or (iv) above with respect to any Environmental
Defect, they shall be deemed to have elected alternative (i), provided that if the existence of the Environmental Defect or the Remediation Amount is disputed, no reduction shall be made in the Closing Cash Contribution pursuant to
Section 3.2(b)(iii) at Closing and instead such adjustment, if any, shall be made as part of the final settlement pursuant to Section 3.6, or if not yet then resolved, thereafter. If the Parties elect the option set forth in
clause (i) above, then the Midstream Companies shall be deemed to have assumed responsibility for all of the costs and expenses attributable to the Remediation of the applicable Environmental Defect (net to their interest in the underlying
properties prior to the Closing) and all Liabilities (net to their interest in the underlying properties prior to the Closing) with respect thereto and the foregoing shall be deemed to constitute obligations of the Midstream Companies. If the
Parties elect the option set forth in 

  

 35 








 
clause (ii) above, EXCO shall implement such Remediation in a manner which is consistent with the requirements of Environmental Laws in a timely fashion
for the type of Remediation that EXCO elects to undertake. EXCO will be deemed to have adequately completed the Remediation required in the immediately preceding sentence (A) upon receipt of a certificate or approval from the applicable
Governmental Authority that the Remediation has been implemented to the extent necessary to comply with existing regulatory requirements or (B) upon receipt of a certificate from a licensed professional engineer reasonably acceptable to BG that
the Remediation has been implemented to the extent necessary to comply with existing regulatory requirements. 
 (c)
Exclusive Remedy. Subject BG’s remedy for a breach of EXCO’s representation contained in Section 4.14 and BG’s rights under Section 13.2, Section 12.1(b) shall be the exclusive right and remedy of BG and the
Contributed Companies with respect to any Environmental Defect. No matter claimed as an Environmental Defect pursuant to this Article 12 may also be claimed as a breach of Section 4.14. 
 (d) Environmental Deductibles. Notwithstanding anything to the contrary, (i) in no event shall there be any adjustments to the
Closing Cash Contribution or other remedies provided by EXCO for any individual Environmental Defect for which the Remediation Amount does not exceed $75,000 (“Individual Environmental Threshold”), and (ii) in no event shall
there be any adjustments to the Closing Cash Contribution or other remedies provided by EXCO for any Environmental Defect for which the Remediation Amount exceeds the Individual Environmental Threshold unless (A) the sum of the Remediation
Amounts of all such Environmental Defects that exceed the Individual Environmental Threshold, in the aggregate, excluding any Remediation Amounts attributable to Subject Assets that are subject to Environmental Defects which EXCO assumes pursuant to
Section 12.1(b)(ii), Environmental Defects with respect to which the Parties elect to have such assets assigned to EXCO pursuant to Section 12.1(b)(iii) and Environmental Defects for which EXCO indemnifies BG pursuant to
Section 12.1(b)(iv) and any Environmental Defects cured by EXCO (B) exceeds the Environmental Deductible, after which point BG shall be entitled to adjustments to the Closing Cash Contribution only with respect to aggregate
Remediation Amounts in excess of such Environmental Deductible. If EXCO and BG elect to have EXCO receive assignment of any Subject Assets related to any Environmental Defect pursuant to Section 12.1(b)(iii), the Closing Cash
Contribution shall be reduced by the reasonably allocated value of such retained Subject Assets and the Remediation Amount for the Environmental Defect relating to such retained Subject Assets will not be counted towards the Environmental
Deductible. 
 (e) Environmental Dispute Resolution. EXCO and BG shall attempt to agree on all Environmental Defects
and Remediation Amounts prior to Closing. If EXCO and BG are unable to agree by Closing, the Environmental Defects and/or Remediation Amounts in dispute shall be exclusively and finally resolved by arbitration pursuant to this
Section 12.1(e). There shall be a single arbitrator, who shall be an environmental attorney with at least 10 years experience in environmental matters in the regional area in which the affected Subject Assets are located, as selected by
mutual agreement of BG and EXCO within 15 days after the Closing Date, and absent such agreement, by the Dallas office of the American Arbitration Association (the “Environmental Arbitrator”). The arbitration proceeding shall be
held in Dallas, Texas and shall be conducted in accordance with the Commercial Arbitration Rules of the American 

  

 36 








 
Arbitration Association, to the extent such rules do not conflict with the terms of this Section. The Environmental Arbitrator shall not have worked as an
employee or outside counsel for any Party or its Affiliates during the five (5) year period preceding the arbitration or have any financial interest in the dispute. The Environmental Arbitrator’s determination shall be made within 20 days
after submission of the matters in dispute and shall be final and binding upon both Parties, without right of appeal. In making his determination, the Environmental Arbitrator shall be bound by the rules set forth in this
Section 12.1 and, subject to the foregoing, may consider such other matters as in the opinion of the Environmental Arbitrator are necessary or helpful to make a proper determination. The Environmental Arbitrator, however, may not award
BG a greater Remediation Amount than the Remediation Amount claimed by BG in its applicable Environmental Defect Notice nor a lower Remediation Amount than the Remediation Amount proposed by EXCO in its response to such Environmental Defect Notice.
The Environmental Arbitrator shall act as an expert for the limited purpose of determining the specific disputed Environmental Defects and/or Remediation Amounts submitted by either Party and may not award damages, interest or penalties to either
Party with respect to any matter. EXCO and BG shall each bear its own legal fees and other costs of presenting its case. Each of EXCO and BG shall bear one-half of the costs and expenses of the Environmental Arbitrator. To the extent that the award
of the Environmental Arbitrator with respect to any Remediation Amount is not taken into account as an adjustment to the Closing Cash Contribution pursuant to Section 3.4 or Section 3.5 and the applicable Party would
otherwise be entitled to an adjustment under the provisions of this Section 12.1, then within 10 days after the Environmental Arbitrator delivers written notice to BG and EXCO of his award with respect to a Remediation Amount, and
subject to this Section 12.1, (i) BG shall pay to EXCO the amount, if any, so awarded by the Environmental Arbitrator to EXCO and (ii) EXCO shall pay to BG the amount, if any, so awarded by the Environmental Arbitrator to BG.
Nothing herein shall operate to cause the Closing to be delayed on account of any arbitration hereunder and to the extent any adjustments are not agreed upon by the Parties as of the Closing, the Closing Cash Contribution shall not be adjusted
therefor as of the Closing and subsequent adjustments thereto, if any, will be made pursuant to Section 3.5, Section 3.6 or this Section 12.1. 
 12.2 NORM, Wastes and Other Substances. BG acknowledges that the Subject Assets have been used for transportation of
Hydrocarbons and that there may be petroleum, produced water, wastes, or other substances or materials located in, on or under the Subject Assets or associated with the Subject Assets. Equipment and sites included in the Subject Assets may contain
asbestos, NORM or other Hazardous Substances. NORM may affix or attach itself to the inside of materials and equipment as scale, or in other forms. The materials and equipment located on the Subject Assets or included in the Subject Assets may
contain NORM and other wastes or Hazardous Substances. NORM containing material and/or other wastes or Hazardous Substances may have come in contact with various environmental media, including water, soils or sediment. Special procedures may be
required for the assessment, remediation, removal, transportation, or disposal of environmental media, wastes, asbestos, NORM and other Hazardous Substances from the Subject Assets. This Section shall not limit BG’s remedies under the other
terms of this Agreement.

 (e) the disposal or transportation of any Hazardous Substances from Subject Assets operated by a Midstream Company attributable to the
period of the Midstream Company’s ownership of the Subject Assets to any location not on the Subject Assets in violation of any Environmental Law; 
 (f) any ERISA Liability, Income Tax Liability or Franchise Tax Liability; 
 (g) any working
interest, royalty, overriding royalty, and other interest owner revenues or proceeds attributable to sales of Hydrocarbons purchased by the Midstream Companies, and rentals and other periodic payments under Rights-of-Way, in each case held in
suspense by any Midstream Company as of Closing, or any interest accrued in escrow accounts for such suspended funds; and 
 (h) any Liability of the Contributed Companies for gross negligence or willful misconduct solely in connection with the operation prior to Closing of the Subject Assets. 
 13.3 Indemnities of BG. Effective as of the Closing, BG and its successors and assigns shall assume, be responsible for, shall pay on a
current basis, and hereby defends, indemnifies, holds harmless and forever releases EXCO and its Affiliates, and all of their respective equity holders, partners and members (excluding, in each case, equity holders, 

  

 38 








 
partners or members solely by virtue of holding publicly traded shares, units or other interests), and directors, officers, managers, employees, agents and
representatives (collectively, “EXCO Indemnified Parties”) and the Company from and against any and all Liabilities arising from, based upon, related to or associated with: 
 (a) any breach by BG of its representations or warranties contained in Article 5; or 
 (b) any breach by BG of its covenants and agreements under this Agreement other than under Article 14; 
 but excepting (in each case) Liabilities against which EXCO is required to indemnify BG under Section 13.2 at the time that the Claim Notice is presented by
the EXCO Indemnified Party to BG. 
 13.4 Limitation on Liability. 
 (a) EXCO shall not have any liability for any indemnification under this Agreement unless (i) the individual amount of any Liability
for which a Claim Notice is delivered by BG to EXCO under this Article 13 and for which EXCO is liable exceeds $75,000, and (ii) the aggregate amount of all Liabilities for which EXCO is liable under this Agreement after the
application of the provisions of clause (i) above exceeds $3,735,000 and then only to the extent such damages or costs exceed $3,735,000; provided that EXCO’s indemnities under Sections 13.2(c) through 13.2(g) and
EXCO’s indemnities in Section 13.2(b) for breaches of Articles 2, 3, 9, 11, 12 and 15 and Sections 4.15(f) – (k), 6.7 and 6.8, shall not be limited by this Section 13.4(a). For
purposes of determining whether there has been a breach of any of EXCO’s representations and warranties for which BG is entitled to indemnification under Section 13.2(a), any dollar or materiality qualifiers in EXCO’s
representations or warranties (except for EXCO’s representations and warranties under Section 4.8(a)) shall be disregarded. 
 (b) Notwithstanding anything to the contrary contained in this Agreement, EXCO shall not be required to indemnify the BG Indemnified Parties or the Contributed Companies for aggregate Liabilities under
Sections 13.2(a) and 13.2(b) in excess of $87,150,000, provided that, EXCO’s indemnitees in Section 13.2(b) for breaches of Articles 1, 3, 9 and 15 and Sections 6.7 and 6.8 shall not be
limited by this Section 13.4(b). 
 (c) The amount of Liability for which an Indemnified Party is entitled to
indemnity under this Article 13 shall be reduced by the amount of insurance proceeds realized by the Indemnified Party or its Affiliates with respect to such Liability (net of any collection costs, and excluding the proceeds of any insurance
policy issued or underwritten by the Indemnified Party or its Affiliates). 
 13.5 Express Negligence. EXCEPT AS
OTHERWISE PROVIDED IN SECTION 10.1(c), THE INDEMNIFICATION, RELEASE, ASSUMED OBLIGATIONS, WAIVER AND LIMITATION OF LIABILITY PROVISIONS PROVIDED FOR IN THIS AGREEMENT SHALL BE APPLICABLE WHETHER OR NOT THE LIABILITIES, LOSSES, COSTS,
EXPENSES AND DAMAGES IN QUESTION AROSE OR RESULTED SOLELY OR IN PART FROM THE GROSS, SOLE, ACTIVE, PASSIVE, CONCURRENT OR COMPARATIVE NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT OR VIOLATION OF LAW OF OR BY ANY INDEMNIFIED PARTY. BG AND EXCO
ACKNOWLEDGE THAT THIS STATEMENT COMPLIES WITH THE EXPRESS NEGLIGENCE RULE AND IS CONSPICUOUS. 
  

 39 








 13.6 Exclusive Remedy. Notwithstanding anything to the contrary contained in
this Agreement, from and after Closing, Sections 10.1(c), 13.2 and 13.3 contains the Parties and the Contributed Companies’ exclusive remedy against each other with respect to breaches of the representations,
warranties, covenants and agreements of the Parties contained in Article 4, Article 5 and Article 6 and the affirmations of such representations, warranties, covenants and agreements contained in the certificate
delivered by each Party at Closing pursuant to Section 9.3(f) or 9.3(g), as applicable. Except for (a) the remedies contained in this Article 13, (b) any other remedies available to the Parties and the Contributed
Companies at Law or in equity for breaches of provisions of this Agreement other than Article 4, Article 5 and Article 6 and (c) the remedies available at Law or in equity in connection with any other
document delivered by a Party in connection with the consummation of the transactions contemplated hereby (other than the certificates delivered by the Parties pursuant to Sections 9.3(f) and 9.3(g)), from and after Closing, EXCO
and BG, on its own behalf and on behalf of its Affiliates and on behalf of the Contributed Companies, each releases, remises, and forever discharges the other and its Affiliates and all such Persons’ equity holders, partners, members, officers,
directors, employees, agents, advisors and representatives from any and all Liabilities 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 this Agreement or the
consummation of the transactions contemplated hereby. Except for the remedies contained in (i) Sections 10.1(c), 13.2 and 13.3, (ii) any other remedies available at Law or in equity for breaches of the provisions
of this Agreement other than Article 4, Article 5 and Article 6 and (iii) the remedies available at Law or in equity in connection with any other document delivered by a Party in connection with the
transactions contemplated hereby or the Assignment or the Limited Liability Company Agreement, but excluding the certificates delivered by the Parties pursuant to Sections 9.3(f) or 9.3(g), effective as of Closing, each Party, on its own
behalf and on behalf of its Affiliates and on behalf of the Contributed Companies, hereby releases, remises and forever discharges the other Party and its Affiliates and all such Persons’ equity holders, partners, members, directors, officers,
employees, agents and representatives from any and all Liabilities in Law or in equity, known or unknown, which such Persons might now or subsequently may have, based on, relating to or arising out of the ownership, use or operation of the Subject
Assets prior to the Closing, or the condition, quality, status or nature of the Subject Assets prior to the Closing, including rights to contribution under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as
amended, breaches of statutory or implied warranties, nuisance or other tort actions, rights to punitive damages, common law rights of contribution, and rights under insurance maintained by either Party or any of its Affiliates. 
 13.7 Indemnification Procedures. All claims for indemnification under Sections 10.1(c), 13.2 and 13.3 shall be asserted
and resolved as follows: 
 (a) For purposes of this Article 13, the term “Indemnifying Party”
when used in connection with particular Liabilities shall mean the Party having an obligation to indemnify another Party or Person(s) with respect to such Liabilities pursuant to this Article 13, and the term “Indemnified
Party” when used in connection with particular Liabilities shall mean the Party or Person(s) having the right to be indemnified with respect to such Liabilities by a Party pursuant to this Article 13. 
  

 40 








 (b) To make claim for indemnification under Sections 10.1(c), 13.2 or 13.3, an
Indemnified Party shall notify the Indemnifying Party of its claim under this Section 13.7, including 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 Party (a “Claim”), the Indemnified Party shall provide its Claim Notice promptly after the Indemnified Party has actual knowledge of the Claim
and shall enclose a copy of all papers (if any) served with respect to the Claim; provided that the failure of any Indemnified Party to give notice of a Claim as provided in this Section 13.7 shall not relieve the Indemnifying Party of its
obligations under Sections 10.1(c), 13.2 or 13.3 (as applicable) except to the extent such failure results in insufficient time being available to permit the Indemnifying Party to effectively defend against the Claim or otherwise materially
prejudices the Indemnifying Party’s ability to defend against the 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 Claim, the Indemnifying Party shall have 30 days from its receipt of the Claim Notice to notify the Indemnified Party whether it admits or denies its obligation to defend the Indemnified Party against such Claim at the
sole cost and expense of the Indemnifying Party. The Indemnified Party is authorized, prior to and during such 30 day period, at the expense of the Indemnifying Party, to file any motion, answer or other pleading that it shall deem necessary or
appropriate to protect its interests or those of the Indemnifying Party and that is not prejudicial to the Indemnifying Party. 
 (d) If the Indemnifying Party admits its obligation to indemnify a Claim, it shall have the right and obligation to diligently defend, at its sole cost and expense, the Claim. The Indemnifying Party shall have full control of such defense
and proceedings, including any compromise or settlement thereof. If requested by the Indemnifying Party, the Indemnified Party agrees to cooperate in contesting any Claim which the Indemnifying Party elects to contest (provided, however, that the
Indemnified Party shall not be required to bring any counterclaim or cross-complaint against any Person). The Indemnified Party may participate in, but not control, at its own expense, any defense or settlement of any Claim controlled by the
Indemnifying Party pursuant to this Section 13.7(d). An Indemnifying Party shall not, without the written consent of the Indemnified Party, (i) settle any Claim or consent to the entry of any judgment with respect thereto which does
not result in a final resolution of the Indemnified Party’s Liability in respect of such Claim (including, in the case of a settlement, an unconditional written release of the Indemnified Party from all Liability in respect of such Claim) or
(ii) settle any Claim or consent to the entry of any judgment with respect thereto in any manner that may materially and adversely affect the Indemnified Party (other than as a result of money damages covered by the indemnity). 
  

 41 








 (e) If the Indemnifying Party does not admit its obligation to indemnify and bear all
expenses associated with a Claim or admits its obligation to indemnify and bear all expenses associated with a Claim but fails to diligently prosecute or settle the Claim, then the Indemnified Party shall have the right to defend against the Claim
at the sole cost and expense of the Indemnifying Party, with counsel of the Indemnified Party’s choosing, subject to the right of the Indemnifying Party to admit its obligation to indemnify and bear all expenses associated with a Claim and
assume the defense of the Claim at any time prior to settlement or final determination thereof. If the Indemnifying Party has not yet admitted its obligation to indemnify and bear all expenses associated with a Claim, the Indemnified Party shall
send written notice to the Indemnifying Party of any proposed settlement and the Indemnifying Party shall have the option for 10 days following receipt of such notice to (i) admit in writing its obligation to indemnify and bear all expenses
associated with a Claim and (ii) if such obligation is so admitted, reject, in its reasonable judgment, the proposed settlement. If the Indemnified Person settles any Claim without the written consent of the Indemnifying Party after the
Indemnifying Party has timely admitted its obligation in writing and assumed the defense of a Claim, the Indemnified Party shall be deemed to have waived any right to indemnity therefor. 
 (f) In the case of a claim for indemnification not based upon a Claim, the Indemnifying Party shall have 30 days from its receipt of the
Claim Notice to (i) cure the Liabilities complained of, (ii) admit its obligation to indemnify for and bear all expenses associated with such Liability or (iii) dispute the claim for such Liabilities. If the Indemnifying Party does
not notify the Indemnified Party within such 30 day period that it has cured the Liabilities or that it disputes the claim for such Liabilities, the amount of such Liabilities shall conclusively be deemed a liability of the Indemnifying Party
hereunder. 
 13.8 Survival. 
 (a) The representations and warranties of the Parties in Articles 4 and 5 (other than the representations and warranties in
Sections 4.6, 4.15, 4.16, 4.18, 4.22, 4.23, 5.7, 5.8 and 5.9) and the covenants and agreements of the Parties in Sections 6.1, 6.2, 6.3 and 9.4 shall survive the Closing for a period of 18 months. The representations and warranties of EXCO
in Sections 4.6, 4.15 and 4.18 shall survive the Closing for the applicable statute of limitations. Subject to the foregoing and as set forth in Section 13.8(b), the remainder of this Agreement (including, without limitation,
Sections 4.16, 4.22, 4.23, 5.7, 5.8 and 5.9) shall survive the Closing without time limit. 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 bona fide 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 Sections 13.2(a), 13.2(b), 13.3(a) and 13.3(b) shall terminate as of the termination date of each respective
representation, warranty, covenant or agreement that is subject to indemnification. EXCO’s indemnities set forth in Section 13.2(d) shall survive the Closing for a period of 18 months. EXCO’s indemnities set forth in
Sections 13.2(c), 13.2(e), 13.2(f), 13.2(g) and 13.2(h) shall survive the Closing without time limit. Notwithstanding the foregoing, there shall be no termination of any bona fide claim asserted pursuant the indemnities in Sections 13.2(a)
through 13.2(h) or Sections 13.3(a) through 13.3(b) prior to the date of termination for such indemnity. 
  

 42 








 13.9 Non-Compensatory Damages. None of the BG Indemnified Parties or EXCO
Indemnified Parties or Contributed Companies shall be entitled to recover from EXCO, BG or the Contributed Companies, or their respective Affiliates, any indirect, consequential, punitive or exemplary damages or damages for lost profits of any kind
arising under or in connection with this Agreement or the transactions contemplated hereby, except to the extent any such Party suffers such damages (including costs of defense and reasonable attorney’s fees incurred in connection with
defending of such damages) to a Third Party, which damages (including costs of defense and reasonable attorney’s fees incurred in connection with defending against such damages) shall not be excluded by this provision as to recovery hereunder.
Subject to the preceding sentence, BG, on behalf of each of the BG Indemnified Parties and the Contributed Companies, and EXCO, on behalf of each of EXCO Indemnified Parties and the Contributed Companies, waive any right to recover punitive,
special, exemplary and consequential damages, including damages for lost profits, arising in connection with or with respect to this Agreement or the transactions contemplated hereby. This Section shall not restrict any Party’s right to obtain
specific performance or other equitable remedies by way of injunction pursuant to Section 14.2. 
 13.10 Exclusion
of Certain Matters. Notwithstanding anything to the contrary elsewhere in this Agreement, (a) claims for Operating Expenses shall be exclusively handled pursuant to Sections 2.4 and 3.2 and shall not be subject to this
Article 13, (b) claims for Environmental Defects asserted under Article 12 shall be handled exclusively under such Article and Article 3 and shall not be subject to this Article 13 and (c) claims with respect to
the termination of this Agreement prior to Closing shall be handled exclusively under Section 3.1 and Article 14 and shall not be subject to this Article 13 (other than Section 13.9, which shall apply in all
respects). 
 ARTICLE 14 
 TERMINATION, DEFAULT AND REMEDIES 
 14.1 Right of Termination. This Agreement and the
transactions contemplated herein may be terminated at any time at or prior to Closing: 
 (a) by EXCO or BG if the Closing
shall not have occurred on or before September 14, 2009 (the “Termination Date”); 
 (b) by EXCO or BG
upon mutual written consent; or 
 (c) by EXCO, if BG fails to deposit the Deposit with the Escrow Agent by the date required
pursuant to Section 3.1. 
 provided, however, that no Party shall have the right to terminate this Agreement pursuant to Section 14.1(a)
above if such Party or its Affiliates willfully failed to perform or observe in any material respect its covenants and agreements hereunder. 
 14.2 Failure to Close and Remedies. Without prejudice to other rights and remedies that may be available to the non-breaching Party, the Parties agree that in the event Closing does not occur by the Termination
Date as a result of the willful breach by a Party of any of its covenants or agreements hereunder in any material respect, the other Party shall be entitled, at its option, in lieu of terminating this Agreement, to enforce specific performance and
other equitable remedies by way of injunction. Each Party agrees to waive any requirement for the posting of a bond in connection with any such equitable relief in favor of the other Party. 
  

 43 








 14.3 Effect of Termination. If the obligation to close the transactions
contemplated by this Agreement is terminated pursuant to any provision of Section 14.1 hereof, then, except for the provisions of Sections 1.1, 1.2, 3.1, 4.16 5.9, 6.6, 10.1(c) and
10.1(e), 10.2, 10.3, 13.9, this Section 14.3, 14.4 and Article 15 (other than Sections 15.2(b), 15.2(c), 15.3, 15.4, 15.7, 15.9, and 15.10), this
Agreement shall forthwith become void and the Parties shall have no liability or obligation hereunder except and to the extent such termination results from the willful breach by a Party of any of its covenants or agreements hereunder; provided that
if EXCO is entitled to retain the Deposit as liquidated damages pursuant to Section 3.1, then such retention shall constitute full and complete satisfaction of any and all remedies and damages EXCO may have against BG under this
Agreement for claims and actions arising at or prior to termination of this Agreement, except for EXCO’s remedies under Sections 5.9, 6.6, 10.1(c) and 10.1(e), 10.2 and 14.4; and provided further that, except as stated above, in the case
of willful breach by either Party, the other Party shall be entitled to all remedies available at Law or in equity and shall be entitled to recover court costs and attorneys’ fees in addition to any other relief to which such Party may be
entitled. 
 14.4 Return of Documentation and Confidentiality. Upon termination of this Agreement, BG shall
destroy or return to EXCO all title, engineering, geological and geophysical data, environmental assessments and/or reports, maps and other information furnished by EXCO to BG or prepared by or on behalf of BG in connection with its due diligence
investigation of the Subject Assets and an officer of BG shall certify as to the return or destruction of such material to EXCO in writing, provided that BG shall be entitled to retain in its corporate records a copy of board papers, reports to
management and other documentation prepared in connection with its decision to enter into the transaction, the conduct thereof, and the termination thereof, so long as it maintains the confidentiality thereof in accordance with the Confidentiality
Agreement. 
 ARTICLE 15 
 MISCELLANEOUS 
 15.1 Exhibits, Schedules and Appendices. All of the Exhibits, Schedules and
Appendices referred to in this Agreement are hereby incorporated into this Agreement by reference and constitute a part of this Agreement. Each Party and its counsel have received a complete set of Exhibits, Schedules and Appendices prior to and as
of the execution of this Agreement. 
 15.2 Expenses and Taxes. 
 (a) Except as otherwise specifically provided, all fees, costs and expenses incurred by BG or EXCO in negotiating this Agreement or in
consummating the transactions contemplated by this Agreement shall be paid by the Party incurring the same, including legal and accounting fees, costs and expenses. 
  

 44 








 (b) All required documentary, filing and recording fees and expenses in connection with
the filing and recording of the assignments, conveyances or other instruments required to convey title to the Contributed Interests to the Company shall be borne by the Company. EXCO shall assume responsibility for, and shall bear and pay, all
federal income taxes, state income taxes, and other similar taxes (including any applicable interest or penalties) incurred or imposed with respect to the transactions described in this Agreement. The Company shall assume responsibility for, and
shall bear and pay, all state sales and use taxes (including any applicable interest or penalties) incurred or imposed with respect to the transactions described in this Agreement. EXCO shall assume responsibility for, and shall bear and pay, all
Asset Taxes assessed with respect to the ownership and operation of the Subject Assets for (i) any taxable period ending prior to the Effective Time and (ii) any Straddle Period in an amount equal to the Asset Taxes imposed for the entire
Straddle Period multiplied by a fraction, the numerator of which is the number of days in the Straddle Period ending immediately prior to the Effective Time and the denominator of which is the number of days in the entire Straddle Period. All Asset
Taxes with respect to the ownership or operation of the Subject Assets arising on or after the Effective Time (including all Straddle Period Asset Taxes not apportioned to EXCO) shall be allocated to and borne by the Company. To the extent the
actual amount of Asset Taxes is not determinable at Closing, the Company and EXCO shall utilize the most recent information available in estimating the amount of Asset Taxes for purposes of Sections 3.2(a)(iii) and 3.2(b)(iv). Upon
determination of the actual amount of Asset Taxes, EXCO shall pay to the Company to the extent not taken into account in the Final Settlement Statement any additional amount necessary to equal EXCO’s share of the Asset Taxes. In the event the
amount of Asset Taxes paid by EXCO or included as a reduction to the Closing Cash Contribution pursuant to Section 3.2(b)(iv) at Closing exceeds EXCO’s share of Asset Taxes, the Company shall pay the amount of any such overage to
EXCO. 
 (c) EXCO shall timely file any return with respect to Asset Taxes due on or before the Closing Date (a
“Pre-Closing Asset Tax Return”) and shall pay any Asset Taxes shown due and owing on such Pre-Closing Asset Tax Return, subject to EXCO’s right of reimbursement for any Asset Taxes for which the Company is responsible under
Section 15.2(b). Within thirty (30) days prior to filing, EXCO shall deliver to BG a draft of any such Pre-Closing Asset Tax Return for BG’s review and approval. 
 (d) EXCO shall assume responsibility for, and shall bear and pay, all Taxes (other than Asset Taxes) assessed with respect to the
ownership and operation of the Subject Assets or ownership of the Contributed Companies for (i) any period ending prior to the Effective Time and (ii) any Straddle Period to the extent such Taxes relate to the period before the Effective
Time, determined using an interim closing of the books method. All Taxes with respect to the ownership or operation of the Subject Assets or ownership of the Contributed Interests arising on or after the Effective Time (including all such Straddle
Period Taxes not apportioned to EXCO) shall be allocated to and borne by the Company. 
 (e) EXCO shall timely file any return
with respect to Taxes (other than Asset Taxes) due on or before the Closing Date and shall pay any Taxes shown due and owing on such Tax return, subject to EXCO’s right of reimbursement for any Taxes for which the Company is responsible under
Section 15.2(a). Within thirty (30) days prior to filing, EXCO shall deliver to BG a draft of any such Tax return for BG’s review and approval. EXCO shall include income 

  

 45 








 
earned by the Contributed Companies through the day prior to the Closing Date on a combined Texas franchise tax report that includes EXCO and the Contributed
Companies; and, the Company shall file a separate combined Texas franchise tax report including the income earned by the Contributed Companies for the period commencing on the Closing Date. 
 15.3 Tax Treatment. The Parties intend and expect that the transactions contemplated by this Agreement 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, as resulting in (a) the creation of the Company, in which EOC and BG will be treated as partners,
(b) subject to clause (d) below, a contribution by EOC of all of the Contributed Interests to the Company in exchange for a 50% interest therein; (c) a contribution by BG of the Final Cash Amount to the Company in exchange for a 50%
interest therein; and (d) a distribution by the Company to EOC of the Final Cash Amount (i) as a reimbursement of EOC’s preformation expenditures with respect to the Contributed Interests within the meaning of Treasury Regulations
Section 1.707-4(d) to the extent applicable, and (ii) in a transaction subject to treatment under Section 707(a) of the Code, and its implementing Treasury Regulations, as in part a sale, and in part a contribution, by EOC of the
Contributed Interests to the Company to the extent Treasury Regulations Section 1.707-4(d) is inapplicable. 
 15.4 Allocation of
Consideration for Tax Purposes. EXCO and BG agree that the portion of the Closing Cash Contribution, as adjusted, treated for federal tax purposes as consideration for a sale transaction (collectively, the “Allocable
Amount”) shall be allocated among the various Subject Assets for federal and state income tax purposes. The initial draft of such allocations shall be prepared in a manner consistent with the valuation of the Subject Assets by EXCO and
shall be provided to BG concurrently with the delivery of the Final Settlement Statement. EXCO, BG and the Company shall then cooperate to prepare a final schedule of the Allocable Amount among the Subject Assets (as adjusted, the
“Allocation Schedule”). The Allocation Schedule shall be updated to reflect any adjustments to the Allocable Amount. The allocation of the Allocable Amount shall be reflected on a completed Internal Revenue Service Form 8594 (Asset
Acquisition Statement under Section 1060) (or similar state or local form), which form will be timely filed separately by EXCO and BG (and/or the Company, as appropriate) with the Internal Revenue Service (or other applicable Governmental
Authority). The portion of the Closing Cash Contribution, as adjusted, other than the Allocable Amount, shall be allocated among the various Subject Assets for purposes of Section 755 of the Code in a manner consistent with the Allocation
Schedule, to the extent Section 755 of the Code is applicable (the “Section 755 Allocation”) Each Party agrees not to (and to cause the Company not to) take any position inconsistent with the allocations set forth in the
Allocation Schedule or the Section 755 Allocation unless required by applicable Law or with the consent of the other Party. 
 15.5 Assignment. This Agreement may not be assigned by any Party, in whole or in part, without the prior written consent of the other Parties, provided that BG shall be entitled to assign its rights and delegate
performance of its obligations to another direct or indirect wholly-owned Affiliate of BG’s ultimate parent company by written notice to EXCO at least 5 Business Days prior to Closing. No assignment hereunder by any Party shall relieve such
Party or its guarantor, if any, of any obligations and responsibilities hereunder or under any related guaranty. 
  

 46 








 15.6 Preparation of Agreement. Both EXCO and BG and their respective counsel
participated in the preparation of this Agreement. In the event of any ambiguity in this Agreement, no presumption shall arise based on the identity of the draftsman of this Agreement. 
 15.7 Publicity. Until after Closing, without reasonable prior notice to the other Party, no Party will issue, or permit any
agent or Affiliate of it to issue, any press releases or otherwise make, or cause any agent or Affiliate of it to make, any public statements with respect to this Agreement and the transactions contemplated hereby, except where such release or
statement is deemed in good faith by the releasing Party to be required by Law or under the rules and regulations of a national stock exchange on which the shares of such Party or any of its Affiliates are listed. In each case to which such
exception applies, prior to making such press release or public statement, the releasing Party will provide a copy of such press release or public statement to the other Party. 
 15.8 Notices. All notices and communications required or permitted to be given hereunder shall be in writing and shall be
delivered personally, or sent by bonded overnight courier, or mailed by U.S. Express Mail or by certified or registered United States Mail with all postage fully prepaid, or sent by telex or facsimile transmission (provided any such telex or
facsimile transmission is confirmed either orally or by written confirmation), addressed to the appropriate Party at the address for such Party shown below or at such other address as such Party shall have theretofore designated by written notice

 15.9 Further Cooperation. After the Closing, BG, EXCO and the Contributed
Companies shall execute and deliver, or shall cause to be executed and delivered from time to time, such further instruments of conveyance and transfer, and shall take such other actions as any Party may reasonably request, to convey and deliver the
Contributed Interests as provided herein in the manner contemplated by this Agreement and to accomplish the transactions contemplated by this Agreement. If any Party receives monies belonging to the other Party, such amount shall immediately be paid
over to the proper Party. If an invoice or other evidence of an obligation is received by a Party, which is partially an obligation of both EXCO and BG, then the Parties shall consult with each other, and each shall promptly pay its portion of such
obligation to the obligee. Prior to Closing, EXCO shall use its commercially reasonable efforts to obtain all consents burdening the Contributed Interests or Subject Assets that are required to permit the assignment of the Contributed Interests by
EXCO as contemplated hereby and the consummation by EXCO of the transactions contemplated hereby; provided, however, EXCO shall not be required to incur any Liability or pay any money in order to be in compliance with the foregoing covenant.

 15.10 Filings, Notices and Certain Governmental Approvals. Promptly after Closing the Parties shall cause the
Contributed Companies to actively pursue all consents and approvals that may be reasonably required in connection with the assignment of the Contributed Interests as contemplated hereby and that shall not have been obtained prior to Closing, and
shall take any and all action reasonably required by any Governmental Authority in order to obtain such unconditional approval, including the posting of any and all bonds or other security that may be required in excess of its existing lease,
pipeline or area-wide bond. 
 15.11 Entire Agreement; Conflicts. THIS AGREEMENT, THE EXHIBITS HERETO, THE

 15.16 Arbitration. 
 (a) Except for matters that are subject to the dispute resolution procedures set forth in Sections 3.6 and 12.1(e) and the matters set
forth in Section 6.6 and 10.2, any Dispute between the Parties shall be resolved through final and binding arbitration. 
 (b) The arbitration shall be conducted in accordance with the Commercial Arbitration Rules of the American Arbitration Association (“AAA”) in effect at the time the arbitration of the Dispute is initiated (the “AAA
Rules”). 
 (c) The arbitration shall be conducted by 3 arbitrators and conducted in Dallas, Texas. Within 30 days of
either Party providing notice to the other Party of a Dispute, each of BG and EXCO shall appoint one arbitrator, and the 2 arbitrators so appointed shall select the third and presiding arbitrator within 30 days following appointment of the second
party-appointed arbitrator. If either Party fails to appoint an arbitrator within the permitted time period or if the Party-appointed arbitrators fail to appoint the presiding arbitrator within the permitted 

  

 50 








 
time period, then the missing arbitrator(s) shall be selected by the AAA as appointing authority in accordance with the AAA Rules. Any arbitrator appointed
by the Party-appointed arbitrators or the AAA shall be a member of the Large, Complex Commercial Case Panel of the AAA or a member of the Center of Public Resources Panel of Distinguished Neutrals. All arbitrators shall be and remain at all times
independent and impartial, and, once appointed, no arbitrator shall have any ex parte communications with any of the Parties concerning the arbitration or the underlying Dispute other than communications directly concerning the selection of the
presiding arbitrator, when applicable. All arbitrators shall be qualified by education, training, or experience to resolve the Dispute. No arbitrator shall have been an employee or consultant to any Party or any of its Affiliates within the 5 year
period preceding the arbitration, or have any financial interest in the Dispute. 
 (d) All decisions of the arbitral tribunal
shall be made by majority vote. The award of the arbitral tribunal shall be final and binding, subject only to grounds and procedures for vacating or modifying the award under the Federal Arbitration Act. Judgment on the award may be entered and
enforced by any court of competent jurisdiction hereunder. 
 (e) Notwithstanding the agreement to arbitrate Disputes in this
Section 15.16, any Party may apply to a court for interim measures pending appointment of the arbitration tribunal, including injunction, attachment, and conservation orders. The Parties agree that seeking and obtaining such
court-ordered interim measures shall not waive the right to arbitration. Additionally, the arbitrators (or in an emergency the presiding arbitrator acting alone in the event one or more of the other arbitrators is unable to be involved in a timely
fashion) may grant interim measures including injunctions, attachments, and conservation orders in appropriate circumstances, which measures may be immediately enforced by court order. Hearings on requests for interim measures may be held in person,
by telephone or video conference, or by other means that permit the Parties to present evidence and arguments. The arbitrators may require any Party to provide appropriate security in connection with such measures. 
 (f) The arbitral tribunal is authorized to award costs, attorneys’ fees, and expert witness fees and to allocate them among the
Parties. The award may include interest, at a rate equal to the one month London Inter-Bank Offer Rate (as published in the Wall Street Journal) plus an additional 2.5 percentage points (or, if such rate is contrary to any applicable usury Law, the
maximum rate permitted by such applicable Law), from the date of any default, breach, or other accrual of a claim until the arbitral award is paid in full. The arbitrators may not award indirect, consequential, special or punitive damages. Unless
otherwise directed by the arbitral tribunal, each Party shall pay its own expenses in connection with the arbitration. 
 (g)
All negotiations, mediation, arbitration, and expert determinations relating to a Dispute (including a settlement resulting from negotiation or mediation, an arbitral award, documents exchanged or produced during a mediation or arbitration
proceeding, and memorials, briefs or other documents prepared for the arbitration) are confidential and may not be disclosed by the Parties, their respective Affiliates and each of their respective employees, officers, directors, counsel,
consultants, and expert witnesses, except to the extent necessary to enforce any settlement agreement, arbitration award, or expert determination, to enforce other rights of a Party, as required by law or regulation, or for a bona fide business
purpose, such as disclosure to accountants, shareholders, or third-party purchasers; provided, however, that breach of this confidentiality provision shall not void any settlement, expert determination, or award. 
  

 51 








 (h) Any papers, notices, or process necessary or proper for an arbitration hereunder, or
any court action in connection with an arbitration or an award, may be served on a Party in the manner set forth in Section 15.8. 
 15.17 Severability. If any term or other provision of this Agreement is invalid, illegal, or incapable of being enforced by any rule of law or public policy, all other conditions and provisions of this Agreement shall
nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any adverse manner to any Party. Upon such determination that any term or other provision is invalid,
illegal, or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner to the end that the transactions
contemplated hereby are fulfilled to the extent possible. 
 15.18 Counterparts. This Agreement may be executed in any number
of counterparts, and each such counterpart hereof shall be deemed to be an original instrument, but all of such counterparts shall constitute for all purposes one agreement. Any signature hereto delivered by a Party by facsimile transmission shall
be deemed an original signature hereto. 
 15.19 Joint and Several Liability. The representations, warranties and covenants
made by (and the obligations of) EOC and Vaughan, as EXCO, in this Agreement are joint and several.
