3.1 Consideration. The aggregate consideration for (a) the transfer by EXCO of the Newco Membership Interests and the
dedication by EXCO of its interests in the Reorganized Subs to the Joint Development Agreement and the creation of the AMI Rights and the Preferential Rights as contemplated therein, (b) the sale by EXCO of the Operator Membership Interests,
and (c) the sale by EXCO of the Midstream Membership Interests (collectively, the “Transaction Components”) shall be an aggregate amount equal to $800,000,000 to be paid in cash at Closing by BG to EXCO (the “Closing
Cash Consideration”), as adjusted pursuant to this Agreement, payable in United States currency by wire transfer in same day funds as and when provided in this Agreement. The portions of the Closing Cash Consideration allocable to the
transaction in clause (a) above (the “Newco Consideration”), that allocable to the transaction referenced in clause (b) above (the “Operator Consideration”) and that allocable to the transaction referenced
in clause (c) above (the “Midstream Consideration”) shall be the amounts set forth on Schedule 3.1 hereto, and each adjustment to the Closing Cash Consideration made pursuant to the provisions of this Agreement shall be
apportioned as an adjustment to the Newco Consideration, the Operator Consideration and/or the Midstream Consideration based upon the Transaction Component(s) to which the adjustment relates. 

3.2 Deposit. 

(a) Within 2 Business Days following the execution of this Agreement (the “Deposit Date”), BG will deposit by wire
transfer in same day funds with Escrow Agent, to be held in escrow pursuant to the Escrow Agreement, an amount equal to $47,500,000 (such amount, together with any interest actually earned thereon, the “Deposit”). If Closing occurs,
the Deposit shall be applied toward the Closing Cash Consideration at the Closing. 
 (b) If the transactions contemplated by
this Agreement are not consummated on or before the Termination Date because of the willful breach by BG of any of its covenants or agreements hereunder in any material respect, including BG’s covenants under Section 9.3 (other than
as a result of EXCO’s breach of this Agreement), then, in such event, EXCO shall have the option to (i) terminate this Agreement, receive the Deposit (and the Parties shall instruct the Escrow Agent to release the Deposit to EXCO pursuant
to the terms of the Escrow Agreement) as liquidated damages and EXCO’s sole and exclusive remedy (other than EXCO’s remedy for breaches by BG of Sections 5.9, 10.1(c) and (e), 10.2 and 14.4) free of any claims by BG
thereto, (ii) seek the rights and remedies set forth in Section 14.2, or (iii) terminate this Agreement, instruct the Escrow Agent to release the Deposit to BG pursuant to the terms of the Escrow Agreement and seek the rights
and remedies set forth in Section 14.3. 
  

 3 








 (c) If this Agreement is terminated by the mutual written agreement of BG and EXCO, or if
the Closing does not occur on or before the Termination Date for any reason other than as set forth in Section 3.2(b), then BG shall be entitled to the delivery of the Deposit, free of any claims by EXCO with respect thereto and BG and
EXCO shall instruct the Escrow Agent to release the Deposit to BG pursuant to the terms of the Escrow Agreement. BG and EXCO shall thereupon have the rights and obligations set forth in Sections 14.2 and 14.3. 

3.3 Adjustments to Closing Cash Consideration. All adjustments to the Closing Cash Consideration shall be made (y) in
accordance with the terms of this Agreement and, to the extent not inconsistent with this Agreement, in accordance with GAAP as consistently applied by EXCO in the preparation of the Illustrative Calculation of Effective Time Working Capital on
Exhibit I-1 and, with respect to any items not reflected in such illustrative calculation, in the preparation of the Unaudited Financials and the Pro Forma Financials and (z) without duplication. The Closing Cash Consideration shall be
adjusted as follows, and the resulting amount shall be herein called the “Adjusted Closing Cash Consideration”: 

(a) The Closing Cash Consideration shall be adjusted upward by the following amounts (without duplication): 

(i) 50% of the aggregate amount of: (A) the capital contributions and intercompany loans (including contributions or loans used to
acquire the Additional Interests) made by EXCO or any of its Affiliates (other than any EXCO Sub) to any EXCO Sub after the Effective Time and through and including March 31, 2010 set forth on Schedule 3.3(a)(i) attached hereto;

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 Price set forth in the Final Settlement
Statement is mutually agreed upon by EXCO and BG, the Final Settlement Statement and the Final Cash Price shall be final and binding on the Parties. 

3.7 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 Deloitte & Touche 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 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, 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 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 (the “AAA”). 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.

Closing Cash Consideration for purposes of Section 15.4.

 6.3 Governmental Bonds. BG acknowledges that none of the bonds, letters of credit and guarantees, if any,
posted by EXCO or its Affiliates (other than any EXCO Sub) with Governmental Authorities and relating to the Subject Interests are transferable in connection with the transactions contemplated hereby. As soon as practicable following the
Reorganization, the Parties shall cause Operator to post bonds or other security required to be posted by Operator as the operator of the Subject Interests with any applicable Governmental Authorities meeting the requirements of such authorities to
own the Subject Interests. 
 6.4 Notifications. If either EXCO or BG obtains actual knowledge that the other
Party apparently has breached a representation, warranty, covenant or other agreement under this Agreement, that Party shall promptly inform the other Party of such potential breach so that it may attempt to remedy or cure such breach prior to
Closing. Notwithstanding the foregoing, this Section shall not apply to breach of the Parties’ obligations at Closing and shall not operate to delay Closing. If any of EXCO’s or BG’s representations or warranties is untrue, or
EXCO’s or BG’s covenants or agreements have not been performed or observed, but such breach or failure is cured to the reasonable satisfaction of the other Party by Closing (or, if Closing does not occur, by the Termination Date), then
such breach or failure shall be deemed not to have occurred for all purposes of this Agreement. Notwithstanding the other terms of this Section 6.4, the other provisions of this Agreement and the various documents and agreements to be
executed and delivered pursuant hereto relating to representations, warranties, indemnities and agreements of EXCO or BG shall not be altered or modified by BG’s or EXCO’s knowledge of any event, or failure to provide notice of the same,
or BG’s or EXCO’s review of any documents or other matters. 
 6.5 HSR Act. Within 10 Business Days
following the execution by BG and EXCO of this Agreement, BG and EXCO will, to the extent necessary, each prepare and simultaneously file with the DOJ and the FTC the notification and report form required for the transactions contemplated by this
Agreement by the HSR Act, and request early termination of the waiting period thereunder. BG and EXCO agree to respond promptly to any inquiries from the DOJ or the FTC concerning such filings and to comply in all material respects with the filing

  

 27 








 
requirements of the HSR Act. BG and EXCO shall cooperate with each other and, subject to the terms of the Confidentiality Agreement, shall promptly furnish all information to the other Party that
is necessary in connection with BG’s and EXCO’s compliance with the HSR Act. BG and EXCO shall keep each other fully advised with respect to any requests from or communications with the DOJ or FTC concerning such filings and shall consult
with each other with respect to all responses thereto. Each of EXCO and BG shall use its reasonable efforts to take all actions reasonably necessary and appropriate in connection with any HSR Act filing to consummate the transactions consummated

6.6 Amendment to Schedules. As of the Closing Date, all Schedules to Article IV may be deemed amended and
supplemented by EXCO to include reference to any matter (a) relating to EXCO or the Subject Interests which first arises or occurs after the date of this Agreement and does not result from a breach by EXCO of any provision of Article IV,
or this Article VI or (b) which results in an adjustment to the Closing Cash Consideration pursuant to Section 3.3 as a result of the removal under the terms of this Agreement of any Subject Interest from the transactions
contemplated by this Agreement. 
 6.7 Additional Interests. The Parties acknowledge that the EXCO Subs will be
acquiring additional Leases in the AMI Area from and after the Effective Time up to (and including) 10 days before the Closing Date (all such Leases actually acquired by EXCO Subs during such period, the “Additional Interests”).

 (a) All Additional Interests acquired up to (and including) 10 Business Days prior to the Execution Date and the amounts paid
by the EXCO Subs for such Additional Interests are set forth on Schedule 6.7. At or prior to Closing, EXCO will amend Schedule 6.7 to reflect all Additional Interests acquired between the Execution Date and the date that is ten days
before the Closing and the amounts paid for such Additional Interests. For all purposes of this Agreement, except to the extent it becomes a Rejected Interest, all Additional Interests shall be treated upon Closing as if they had been acquired by
the applicable EXCO Sub prior to the Reorganization and will be treated as Subject Non-Operating Assets, Operating Assets, Gathering Assets and/or other assets, as applicable, of the EXCO Subs. EXCO will use its commercially reasonable efforts to
assign a share of its rights and obligations under the acquisition documents related to each Additional Interest to BG; provided that EXCO shall not be required to pay cash or otherwise surrender value or incur any liability to obtain any such
assignment. 
 (b) BG will have the right, up to 60 days following the Closing, to reject the acquisition of any Additional
Interest (any such rejected Additional Interest, a “Rejected Interest”). Any such election by BG shall be communicated to EXCO by written notice (each, a “Rejection Notice”). The Adjusted Closing Cash Consideration
shall account for any Rejected Interests that are the subject of a Rejection Notice delivered to EXCO not less than seven (7) Business Days prior to the Closing as provided in Section 3.3(b)(viii). In the case of any Rejection
Notice delivered after the day that is seven (7) Business Days prior to the Closing, promptly following any such rejection (but in any event, after the Closing), the applicable Newco shall convey, and EXCO and BG shall cause Operator to convey,
the applicable Rejected Interests to EXCO pursuant to an assignment with a special warranty of 
  

 28 








 
title against claims by, through or under the applicable assignor or its Affiliates, but not otherwise, and upon EXCO’s receipt of such assignments, EXCO shall pay BG the amount paid for
the applicable Rejected Interests as set forth on Schedule 6.7. The Parties agree to take any and all measures necessary to effectuate any such conveyances of Rejected Interests requested by BG in a timely delivered Rejection
Notice. 
 6.8 Negotiation of Ancillary Agreements and Development Plans and Budgets. Each of EXCO and BG
shall use its reasonable efforts to complete negotiation of and agree in writing upon the form of the Ancillary Agreements and the forms of the Development Plans and Budgets to be attached as Exhibits to the Joint Development Agreement.

(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, including Third Party operators of the Assets (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
Assets and all Records and other documents in EXCO’s or any of its Affiliates’ possession relating primarily to the Assets or the EXCO Subs. 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 Assets or the EXCO Subs 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 Assets or the EXCO Subs 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 and any applicable Third Party operator’s safety rules, regulations and operating policies of which they are informed while conducting its due diligence evaluation of the Assets including any
environmental or other inspection or assessment of the Assets. 
 (b) Before conducting any sampling, boring, drilling or other
invasive investigation activities (“Invasive Activities”) on or with respect to any of the Properties, 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 Properties, 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 AECOM and DNV as environmental consulting firms that may conduct such
Invasive Activities, and each of AECOM and DNV is hereby deemed to be a “BG’s Representative.” BG, AECOM or DNV shall obtain all permits necessary to conduct 

 

 36 








 
any such Invasive Activities from any applicable Governmental Authorities, provided that upon request, EXCO shall provide BG, AECOM or DNV with assistance (at no cost or liability to EXCO)
reasonably requested by BG, AECOM or DNV that may be necessary to secure such permits. EXCO shall have the right, at its option and expense, to split any samples collected from the Properties with BG. 

(c) BG hereby defends, indemnifies and holds harmless each of the operators of the Assets and 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 Affiliates’ or any Third Party operator’s rules, regulations or operating policies of which BG or 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 or the EXCO Subs (whether prior to or after the execution hereof), 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 AECOM or DNV 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 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 Assets in connection with BG’s due diligence, (ii) restore the 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 Assets in connection with BG’s due diligence. Any disturbance to the Assets (including the real property associated with such
Assets) resulting from BG’s due diligence will be promptly corrected by BG.

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 Assets that are excluded from the transactions contemplated hereby pursuant to the provisions of this Agreement, and (b) the Excluded Assets).

ARTICLE XI 

TITLE MATTERS; CASUALTIES; TRANSFER RESTRICTIONS 

11.1 General Disclaimer of Title Warranties and Representations. Without limiting
BG’s remedies for Title Defects set forth in this Article XI, EXCO makes no warranty or representation, express, implied, statutory or otherwise, with respect to EXCO’s title to any of the Assets and BG hereby acknowledges and
agrees that BG’s sole remedy for any defect of title, including any Title Defect, with respect to any of the Subject Interests (a) on or before the Title Defect Claim Date, shall be as set forth in Section 11.2 and
(b) without duplication, from and after the Title Defect Claim Date, shall be under Section 13.1(b) relating to a breach by EXCO of Section 6.1(f) or Section 6.1(h). 

11.2 Notice of Title Defects; Defect Adjustments. 

(a) Title Defect Notices. On or before the Title Defect Claim Date, BG may deliver claim notices to EXCO meeting the requirements
of this Section 11.2(a) (collectively the “Title Defect Notices” and individually a “Title Defect Notice”) setting forth any matters which, in BG’s reasonable opinion, constitute Title Defects and
which BG intends to assert as a Title Defect pursuant to this Article XI. For all purposes of this Agreement and notwithstanding anything herein to the contrary, BG shall be deemed to have waived, and EXCO shall have no liability for,
any Title Defect which BG fails to assert as a Title Defect by a Title Defect Notice 
  

 39 








 
received by EXCO on or before the Title Defect Claim Date, provided that any breach of Section 4.7 or Section 4.25 which could also be a Title Defect may be resolved pursuant to
Article XIII, or as a Title Defect pursuant to this Article XI, but not both, and, provided further, that any breach of Section 4.4 or Section 4.10 shall be resolved only pursuant to such Section and may not be
asserted as a Title Defect. To be effective, each Title Defect Notice shall be in writing, and shall include (i) a description of the alleged Title Defect(s), (ii) the Warranty Wells or Leases affected by the Title Defect (each a
“Title Defect Property”), (iii) the Allocated Value and Allocated Carry of the Subject Interest in each Title Defect Property, (iv) supporting documents available to BG reasonably necessary for EXCO to verify the existence
of the alleged Title Defect(s), and (v) the amount by which BG reasonably believes the Allocated Value and Allocated Carry of the Subject Interest in each Title Defect Property is reduced by the alleged Title Defect(s) and the computations upon
which BG’s belief is based. To give EXCO an opportunity to commence reviewing and curing Title Defects, BG agrees to use reasonable efforts to give EXCO, during the period prior to the Title Defect Claim Date, periodic written notices of all
Title Defects discovered by BG since the last such interim notice, which interim notices may be preliminary in nature and supplemented prior to the expiration of the Title Defect Claim Date, provided that failure to provide preliminary notice of a
Title Defect shall not prejudice BG’s right to assert such Title Defect hereunder. BG shall also on or before the Title Defect Claim Date furnish EXCO with written notice of any Title Benefit which is reported by any of BG’s or any of its
Affiliate’s employees, title attorneys, landmen or other title examiners to the BG employee directly responsible for undertaking and supervising BG’s title diligence activities hereunder while conducting BG’s due diligence with
respect to the Assets prior to the Title Defect Claim Date. 
 (b) Title Benefit Notices. In addition to any Title
Benefits reported by BG pursuant to Section 11.2(a), EXCO shall have the right, but not the obligation, to deliver to BG on or before the Title Defect Claim Date a notice setting forth any additional matters which, in EXCO’s
reasonable opinion, constitute Title Benefits and which EXCO intends to assert as Title Benefits pursuant to this Article XI (each, a “Title Benefit Notice”). To be effective, each Title Benefit Notice shall be in writing,
and shall include (i) a description of the Title Benefit, (ii) the Warranty Wells or Leases affected by the Title Benefit, (iii) supporting documents available to EXCO reasonably necessary for BG to verify the existence of the alleged
Title Benefit and (iv) the amount by which EXCO reasonably believes the Allocated Value and Allocated Carry of the Subject Interest in each affected Lease is increased by the alleged Title Benefit and the computations upon which EXCO’s
belief is based. Other than Title Benefits which BG is required to report to EXCO pursuant to Section 11.2(a), EXCO shall be deemed to have waived all Title Benefits of which it has not given notice on or before the Title Defect Claim
Date. 
 (c) EXCO’s Right to Cure. EXCO shall have the right, but not the obligation, to attempt, at its sole cost,
to cure at any time prior to the Title Defect Remedy Date (the “Title Cure Period”), any Title Defects of which it has been advised by BG. 

(d) Remedies for Title Defects. With respect to any Title Defect that has not been waived in writing by BG, or cured on or before
the Title Defect Remedy Date, subject to EXCO’s right to dispute the existence of such Title Defect and/or the Title Defect Amount or Title Carry Reduction Amount asserted with respect thereto and subject to the applicable Individual Title
Defect Threshold and the Title Deductible (except with respect to Title Defects relating to Pineton Warranty Wells and/or Pineton Leases), the Parties shall mutually elect to: 

(i) subject to the applicable Individual Title Defect Threshold and the Title Deductible (except with respect to Title Defects relating
to Pineton Warranty Wells and/or Pineton Leases), make a payment from EXCO to BG in an amount equal to the Title Defect Amount of such Title Defect, and reduce the Carried Cost Obligation by an amount equal to the Title Carry Reduction Amount for
such Title Defect; 
  

 40 








 (ii) have the applicable Newco and the Operator reassign to EXCO, with special warranty of
title against claims by, through or under such Person, but not otherwise, the Title Defect Property that is subject to such Title Defect, together with all associated Assets, and, concurrently therewith, EXCO shall pay to BG an amount equal to the
Allocated Value of the Subject Interest attributable to such Title Defect Property and the Carried Cost Obligation shall be reduced by an amount equal to the Title Carry Reduction Amount attributable to such Title Defect Property and such property
and assets shall become Excluded Assets hereunder; or 
 (iii) have EXCO indemnify BG with respect to such Title Defect by an
indemnity in form and substance satisfactory to BG. 
 In the event that the Parties do not agree in writing by the Title Defect Remedy Date on
an election of alternative (i), (ii) or (iii) above with respect to any Title Defect, they shall be deemed to have elected alternative (i), provided that if the existence of a Title Defect or the Title Defect Amount asserted with respect
thereto is disputed, no payment shall be made until the dispute is resolved pursuant to Section 11.2(j). 
 (e)
Remedies for Title Benefits. 
 (i) In the case of each Title Benefit, the aggregate Title Defect Amounts attributable to
all uncured Title Defects shall be reduced by an amount equal to the Title Benefit Amount of such Title Benefit and the aggregate Title Carry Reduction Amounts attributable to all uncured Title Defects shall be reduced by an amount equal to the
Title Carry Increase Amount for such Title Benefit. 
 (ii) Notwithstanding anything to the contrary, (A) in no
event shall there be any adjustments to the Final Cash Price or reductions to the aggregate Title Defect Amount or increases in the Carried Cost Obligation for any individual Title Benefit for a Warranty Well for which the Title Benefit Amount does
not exceed $25,000, or for any individual Title Benefit for a Lease for which the Title Benefit Amount does not exceed $10,000 (in either case, the applicable “Individual Title Benefit Threshold”), (B) in no event shall there
be any adjustments to the Final Cash Price or reductions to the aggregate Title Defect Amount or increases in the Carried Cost Obligation unless the sum of the Title Benefit Amounts of all Title Benefits in excess of the applicable Individual Title
Benefit Threshold exceeds $9,500,000 and (C) in no event shall there be any adjustments to the Final Cash Price or reductions to the aggregate Title Defect Amount to the extent the aggregate of such Title Benefit Amounts in excess of the
applicable Individual Title Benefit Threshold exceed the aggregate Title Defect Amounts and (D) in no event shall there be any increases in the Carried Cost Obligation (I)

 

 41 








 
unless there is an adjustment for the related Title Benefit Amount, and then only in the same proportion as an adjustment is made for the related Title Benefit Amount or (II) to the extent the
aggregate of Title Carry Increase Amounts related to Title Benefit Amounts in excess of the Individual Title Benefit Threshold exceed the aggregate Title Carry Reduction Amounts. The Parties agree that if the same Title Benefit affects more than one
Lease, then the Title Benefit Amounts for each Lease affected by such Title Benefit shall be aggregated for the purposes of determining whether the applicable Individual Title Benefit Threshold has been met with respect to such Title Benefit.

 (f) Exclusive Remedy. Except for BG’s rights under Section 13.1(a) relating to a breach by EXCO of
Sections 4.7 or 4.25 which could also be a Title Defect and under Section 13.1(b) relating to a breach by EXCO of Section 6.1(f) or 6.1(h), the provisions of Section 11.2(d) shall be the
exclusive right and remedy of BG with respect to the failure of the EXCO Subs to have Defensible Title with respect to any Asset. 

(g) Title Defect Amount. The Title Defect Amount resulting from a Title Defect shall be the amount by which the Allocated Value of
the Subject Interest attributed to the affected Title Defect Property is reduced as a result of the existence of such Title Defect and shall be determined in accordance with the following terms and conditions: 

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

(ii) if the Title Defect is an Encumbrance 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 Title Defect Property; 
 (iii) if the Title Defect represents a
discrepancy between (A) the Net Revenue Interest for any Title Defect Property and (B) the Net Revenue Interest stated in Exhibit B (or, with respect to a Lease in Exhibit A, the Net Revenue Interest determined by
subtracting the royalties, overriding royalties and other burdens shown on Exhibit A for such Lease from 100%) and the Working Interest is not reduced proportionately, then the Title Defect Amount shall be the product of the Allocated Value
of the Subject Interest attributed to such Title Defect Property multiplied by a fraction, the numerator of which is the Net Revenue Interest decrease and the denominator of which is the Net Revenue Interest stated in Exhibit B (or, with
respect to a Lease in Exhibit A, the Net Revenue Interest determined by subtracting the royalties, overriding royalties and other burdens shown on Exhibit A for such Lease from 100%); 

(iv) if the Title Defect represents a discrepancy between (A) the Net Acres for any Title Defect Property and (B) the Net
Acres for such Title Defect Property stated in Exhibit A, then the Title Defect Amount shall be the product obtained by multiplying the positive difference between such Net Acres amounts by the Net Acre Allocation applicable to such Title
Defect Property; 
 (v) if the Title Defect represents an obligation or Encumbrance upon or other defect in title to the Title
Defect Property of a type not described above, the Title Defect Amount shall be determined by taking into account the Allocated Value of the Subject Interest 

 

 42 








 
attributed to the Title Defect Property, the portion of the Title Defect Property 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 values placed upon the Title Defect by BG and EXCO and such other reasonable factors as are necessary to make a proper evaluation; provided, however, that if such Title Defect is reasonably
capable of being cured, the Title Defect Amount shall not be greater than the lesser of (A) the reasonable cost and expense of curing such Title Defect and (B) the Allocated Value of the Subject Interest attributable to the Title Defect
Property; 
 (vi) the Title Defect Amount with respect to a Title Defect Property shall be determined without duplication of
any costs or losses included in another Title Defect Amount pertaining to such Title Defect Property hereunder; and 
 (vii)
notwithstanding anything to the contrary in this Article XI, 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 the Subject Interest
attributable to such Title Defect Property. 
 The Title Carry Reduction Amount resulting from a Title Defect shall equal the same percentage of
the Allocated Carry for each affected Lease that the Title Defect Amount bears to the Allocated Value of such Lease. Notwithstanding anything to the contrary in this Article XI, the aggregate Title Carry Reduction Amounts attributable to
the effects of all Title Defects upon any Title Defect Property shall not exceed the Allocated Carry of the Conveyed Interest attributable to such Title Defect Property. 

(h) Title Benefit Amount. The Title Benefit Amount resulting from a Title Benefit shall be determined in accordance with the
following methodology, terms and conditions: 
 (i) if BG and EXCO agree on the Title Benefit Amount, then that amount shall be
the Title Benefit Amount; and 
 (ii) if the Title Benefit represents a discrepancy between (A) the Net Revenue Interest
for any Warranty Well or Lease and (B) the Net Revenue Interest stated in Exhibit B (or, with respect to a Lease in Exhibit A, the Net Revenue Interest determined by subtracting the royalties, overriding royalties and other
burdens shown on Exhibit A for such Lease from 100%) and the Working Interest is not increased proportionately, then the Title Benefit Amount shall be the product of the Allocated Value of the Subject Interest attributable to the affected
Warranty Well or Lease multiplied by a fraction, the numerator of which is the Net Revenue Interest increase and the denominator of which is the Net Revenue Interest stated in Exhibit B (or, with respect to a Lease in Exhibit A,
the Net Revenue Interest determined by subtracting the royalties, overriding royalties and other burdens shown on Exhibit A for such Lease from 100%); provided that if the Net Revenue Interest increase does not affect the Warranty Well
or Lease throughout the entire life of the Warranty Well or Lease, the Title Benefit Amount determined under this Section 11.2(h) shall be reduced to take into account the applicable time period only; and 

 

 43 








 (iii) If the Title Benefit represents a discrepancy between (A) the Net Acres for any
Lease and (B) the Net Acres for such Lease stated in Exhibit A, then the Title Benefit Amount shall be the product obtained by multiplying the positive difference between such Net Acres amounts by the Net Acre Allocation applicable to
such Lease. 
 The Title Carry Increase Amount resulting from a Title Benefit shall equal the same percentage of the Allocated Carry for each
affected Lease that the Title Benefit Amount bears to the Allocated Value of such Lease. 
 (i) Title Deductibles.
Notwithstanding anything to the contrary herein, but subject to the following sentence, (i) in no event shall there be any adjustments to the Final Cash Price or other remedies provided by EXCO (including Section 11.2(d)) or
reductions in the Carried Cost Obligation for any individual Title Defect for a Warranty Well for which the Title Defect Amount does not exceed $25,000, or for any individual Title Defect for a Lease for which the Title Defect Amount does not exceed
$10,000 (in either case, the applicable “Individual Title Defect Threshold”), (ii) in no event shall there be any adjustments to the Final Cash Price or other remedies provided by EXCO (for any Title Defect that exceeds the
applicable Individual Title Defect Threshold) pursuant to Section 11.2(d)(i) unless (A) the sum of the Title Defect Amounts of all such Title Defects that exceed the applicable Individual Title Defect Threshold, in the aggregate,
excluding any Title Defect Amounts attributable to Title Defects cured by EXCO, Title Defect Properties distributed to, and retained by, EXCO pursuant to Section 11.2(d)(ii) or Title Defect Properties for which EXCO indemnifies BG
pursuant to Section 11.2(d)(iii) exceeds (B) the Title Deductible, after which point BG shall be entitled to such remedies only with respect to aggregate Title Defect Amounts in excess of such Title Deductible, and (iii) in no
event shall there be any decreases in the Carried Cost Obligation unless there is an adjustment for the related Title Defect Amount, and then only in the same proportion as an adjustment is made for the related Title Defect Amount. BG shall be
entitled to adjustments to the Final Cash Price, other remedies provided by EXCO (including Section 11.2(d)) and/or reductions in the Carried Cost Obligation for each Title Defect relating to Pineton Warranty Wells and/or Pineton Leases
without regard to whether the Title Defect Amount for such Title Defect satisfies the Individual Title Defect Threshold, and without regard to whether the Title Deductible has been satisfied. The Parties agree that if the same Title Defect affects
more than one Lease, then the Title Defect Amounts for each Lease affected by such Title Defect shall be aggregated for the purposes of determining whether the applicable Individual Title Defect Threshold has been met with respect to such Title
Defect. If the Parties elect to have any Title Defect Property distributed to, and retained by, EXCO pursuant to Section 11.2(d)(ii), then the Final Cash Price shall be reduced by the Allocated Value of the Subject Interest attributable
to such Title Defect Property, the Carried Cost Obligation shall be reduced by the Allocated Carry of the Subject Interest attributable to such Title Defect Property and the Title Defect Amount relating to such Subject Interest will not be counted
towards the Title Deductible. 
 (j) Title Dispute Resolution. EXCO and BG shall attempt to agree on all disputes
relating to Title Defects, Title Benefits, and the Title Defect Amounts, Title Carry Reduction Amounts, Title Benefit Amounts and Title Carry Increase Amounts relating thereto prior to the Title Remedy Date. If EXCO and BG are unable to agree by
such date, such disputes shall be exclusively and finally resolved pursuant to this Section 11.2(j). There shall be a single 

 

 44 








 
arbitrator, who shall be a title attorney with at least 10 years experience in oil and gas titles involving properties in the regional area in which the Title Defect Properties are located, as
selected by mutual agreement of BG and EXCO within 15 days after the end of the applicable Title Cure Period, and absent such agreement, by the Dallas office of the AAA (the “Title Arbitrator”). The Title Arbitrator shall not have
worked as an employee or outside counsel for any Party or its Affiliates during the 5 year period preceding the arbitration or have any financial interest in the dispute. The arbitration proceeding shall be held in Dallas, Texas and shall be
conducted in accordance with the Commercial Arbitration Rules of the AAA, to the extent such rules do not conflict with the terms of this Section. The Title 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 Title Arbitrator shall be bound by the rules set forth in Sections 11.2(g) and 11.2(h) and, subject to the
foregoing, may consider such other matters as in the opinion of the Title Arbitrator are necessary to make a proper determination. The Title Arbitrator, however, may not award BG a greater Title Defect Amount or Title Carry Reduction Amount than the
Title Defect Amount or Title Carry Reduction Amount claimed by BG in its applicable Title Defect Notice nor a lower Title Defect Amount or Title Carry Reduction Amount than the Title Defect Amount or Title Carry Reduction Amount proposed by EXCO in
its response to such Title Defect Notice and may not award EXCO a greater Title Benefit Amount or Title Carry Increase Amount than the Title Benefit Amount or Title Carry Increase Amount claimed by EXCO in its applicable Title Benefit Notice nor a
lower Title Benefit Amount or Title Carry Increase Amount than the Title Benefit Amount or Title Carry Increase Amount proposed by BG in its response to such Title Benefit Notice. The Title Arbitrator shall act as an expert for the limited purpose
of determining the specific disputed Title Defect, Title Benefit, Title Defect Amounts, Title Carry Reduction Amounts, Title Benefit Amounts and/or Title Carry Increase 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 Title Arbitrator. To the extent
that the award of the Title Arbitrator with respect to any Title Defect Amount or any Title Benefit Amount is not taken into account as an adjustment to the Final Cash Price pursuant to Section 3.6 and the applicable Party would
otherwise be entitled to an adjustment under the provisions of this Section 11.2, then within 10 days after the Title Arbitrator delivers written notice to BG and EXCO of his award with respect to such Title Defect Amount or such Title
Benefit Amount, (A) BG shall pay to EXCO the amount, if any, so awarded by the Title Arbitrator to EXCO and (B) EXCO shall pay to BG the amount, if any, so awarded by the Title Arbitrator to BG. 

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
Interests, Midstream LLC, Newcos and the Operator shall assume all risk of loss with respect to production of Hydrocarbons through normal depletion (including watering out of any well, collapsed casing or sand infiltration of any well) and the
depreciation of personal property due to ordinary wear and tear, in each case, and BG shall not assert such matters as any casualty losses or Title Defects hereunder. 

 

 45 








 (b) If, after the date of this Agreement but prior to the Closing Date, any portion of the
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 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 the Newcos, Operator and Midstream LLC, as applicable, through a document to be delivered at Closing reasonably acceptable to EXCO and BG against any costs or expenses that any of the Newcos, Operator or
Midstream LLC reasonably incurs to repair or restore any Assets affected by such casualty or taking. In each case, EXCO and its Affiliates shall retain 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 Asset or portion thereof after the date of this Agreement, but no taking of such 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 Newcos, Operator and Midstream LLC or subrogate such Persons to all of EXCO’s and its Affiliates’ 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 Interests threatened to be taken, except that EXCO and its Affiliates shall reserve and retain (and the Newcos, Operator
and Midstream LLC shall assign to EXCO) all rights, titles, interests and claims against Third Parties for the recovery of EXCO’s and its Affiliates’ costs and expenses incurred prior to the Closing in defending or asserting rights in such
action with respect to the Subject Interests. 
 11.4 Preferential Purchase Rights and Consents to Assign.

 (a) Within three Business Days after the Execution Date, the Parties will jointly decide the applicability of any preferential
purchase right to the transactions contemplated hereby and, 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. For the avoidance of doubt, if the Parties are not able to come to agreement regarding the applicability of a specific preferential purchase right to the transactions contemplated hereby, such preferential purchase
right shall be considered applicable and EXCO will send a notice to the holder of such right pursuant to the terms of this Section 11.4. In addition, within three Business Days after the Execution Date, the Parties will jointly decide
the applicability of any right to consent to assignment pertaining to the Subject Interests and the transactions contemplated hereby and, EXCO, within 10 days after the date of this Agreement, shall send to each holder of such an applicable consent
right a notice, in material compliance with the contractual provisions applicable to such right, seeking such holder’s consent to the transactions contemplated hereby. For the avoidance of doubt, if the Parties are not able to come to agreement
regarding the applicability of a specific right to consent to assignment pertaining to the Subject Interests and the transactions contemplated hereby, such consent right shall be considered applicable and EXCO will send a notice to the holder of
such right pursuant to the terms of this Section 11.4. Any preferential purchase right must be 
  

 46 








 
exercised subject to all terms and conditions set forth in this Agreement, including the successful closing of this Agreement pursuant to Article IX and the obligation to bear the
Allocated Carry for such Subject Interest based upon the terms of the Joint Development Agreement. The consideration payable under this Agreement for any particular Subject Interest for purposes of preferential purchase right notices shall be the
Allocated Value of such Subject Interest. 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 Interest to which its preferential purchase right applies, then the Subject Interest shall be excluded from the Subject Interests to the extent of the interest affected by the preferential purchase right, such Subject Interest shall be
distributed to EXCO, the Closing Cash Consideration shall be reduced by the Allocated Value of the relevant Subject Interest and the Carried Cost Obligation shall be reduced by the Allocated Carry for the relevant Subject Interest (and such Subject
Interest shall be considered an Excluded Asset for purposes of the other adjustments in Section 3.3). EXCO shall be entitled to all proceeds paid by a Person exercising a preferential purchase right prior to the Closing. If such holder
of such preferential purchase right thereafter fails to consummate the purchase of the Subject Interest covered by such right, then EXCO shall so notify BG, and BG shall purchase on or before 10 days following receipt of such notice, subject to
BG’s satisfaction that such preferential purchase right has been waived or the time for exercising such right has expired, such Subject Interest from EXCO, under the terms of this Agreement for a price equal to the portion of the Closing Cash
Consideration previously allocated to it, as adjusted pursuant to Section 3.3 and the Carried Cost Obligation shall be increased by the amount of the previous reduction for the Allocated Carry for the relevant Subject Interest.

 (c) All Subject Interests for which preferential purchase rights have been waived, or as to which the period to exercise such
right has expired prior to the Closing, shall be retained by Midstream LLC, the Newcos and/or the Operator, as applicable, at the Closing pursuant to the provisions of this Agreement. If, for any reason, any preferential purchase right burdening a
Subject Interest is validly exercised after the Closing, BG shall cause the Newcos, and BG and EXCO shall cause Operator and Midstream LLC, to convey the relevant Subject Interest to the holder of such preferential purchase right in accordance with
the terms thereof, BG shall be entitled to the proceeds paid by the holder of such preferential purchase right with respect to such Subject Interest, and the Carried Cost Obligation shall be reduced by the Allocated Carry for such Subject Interest.

 (d) If (i) EXCO fails to obtain a consent set forth in Schedule 4.4, Part 2 prior to the Closing and the failure
to obtain such consent would cause (A) the indirect assignment of the Subject Interest affected thereby to BG to be void or (B) the termination of a Lease 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 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 that portion of such Subject Interest shall be excluded from the Subject Interests to be conveyed to BG, such Subject Interest

  

 47 








 
shall be distributed to EXCO, the Closing Cash Consideration shall be reduced by the Allocated Value of that portion of such Subject Interest and the Carried Cost Obligation shall be reduced by
the Allocated Carry of that portion of such Subject Interest. In the event that such required consent (with respect to a Subject Interest excluded pursuant to this Section 11.4(d)) that was not obtained prior to Closing is obtained
following Closing then within 10 days after such consent is obtained, BG shall cause either Newco, Operator or Midstream LLC, as applicable, to purchase such Subject Interest that was so excluded, pay to EXCO the amount by which the Closing Cash
Consideration was reduced with respect to such Subject Interest or portion thereof, the Carried Cost Obligation shall be increased by the amount of the previous reduction for the Allocated Carry and EXCO shall assign to such Person such Subject
Interest or portion thereof pursuant to an assignment with a special warranty of title against claims by, through or under EXCO and its Affiliates, but not otherwise. 

(e) If (i) EXCO fails to obtain a consent set forth in Schedule 4.4, Part 2 prior to the Closing and the failure to obtain
such consent would not cause (A) the indirect assignment of the Subject Interest affected thereby to BG to be void or (B) the termination of a Lease 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 Interest subject to such failed consent shall be retained by Midstream LLC, the Newcos and/or the Operator, as applicable, at Closing as part of the Subject Interests and BG
shall have no claim against, and EXCO shall have no Liability for, the failure to obtain such consent; provided that if the affected Subject Interest subject to such requirement is a Well or Lease, then BG may elect prior to Closing to treat the
unsatisfied consent requirement affecting such Well or Lease as a Title Defect (provided that such Title Defect shall not be subject to the Individual Title Defect Threshold or the Title Deductible) and receive the appropriate adjustment to the
Final Cash Price in accordance with Section 11.2. 
 ARTICLE XII 

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”) on or before the applicable Environmental 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 4.15 and BG’s rights under Section 13.1, BG 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 final Environmental Defect Claim Date. Notwithstanding anything to the contrary herein, if environmental diligence conducted by BG or its designees (including AECOM or DNV) shows
reasonable evidence that a material portion of the Properties upon which environmental diligence was conducted is subject to an Environmental Defect that could potentially be a systemic 

 

 48 








 
Environmental Defect affecting other Properties (a “Potential Systemic Environmental Defect”), BG shall have the right, which right shall be exercised (if at all) by notice to
EXCO at any time prior to the occurrence of the Post-Closing Environmental Defect Claim Date, to extend the Post-Closing Environmental Defect Claim Date by 60 days in respect of Environmental Defects asserted by BG on other Properties that are
substantially similar to the Potential Systemic Environmental Defect. 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 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. BG shall use its good faith efforts to inform EXCO of any Environmental Defect relating to the Assets of which BG obtains knowledge prior to Closing through the environmental
diligence conducted by BG or its designees (including AECOM or DNV) or otherwise. EXCO shall have the right, but not the obligation, to cure any properly claimed Pre-Closing Environmental Defect on or before Closing. 

(b) EXCO’s Right to Cure. EXCO shall have the right, but not the obligation, to attempt, at its sole cost, to cure at any
time prior to (i) Closing, in the case of any Pre-Closing Environmental Defects, and (ii) the Post-Closing Environmental Defect Remedy Date, in the case of any Post-Closing Environmental Defects (the “Environmental Cure
Period”), any Environmental Defects of which it has been advised by BG. 
 (c) Remedies for Environmental
Defects. 
 (i) In the event that any Pre-Closing 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 right to dispute the existence of a Environmental Defect and/or the Remediation Amount asserted with respect thereto, the Parties
shall mutually elect to: 
 (A) subject to the Individual Environmental Threshold and the Environmental Deductible, reduce the
Closing Cash Consideration by the Remediation Amount; 
 (B) to the extent attributable to the Subject Interests, have EXCO
assume responsibility for the Remediation of such Environmental Defect and indemnify and hold harmless the BG Indemnified Parties from and against all Liabilities associated with such Environmental Defect and Remediation by an indemnity in form and
substance satisfactory to BG; 
 (C) have the entirety of the Asset, or, at the option of BG, that portion of such Asset
pertaining to the Shallow Rights, that is subject to such Environmental Defect, together with all associated Assets, distributed to, and retained by EXCO in which event the Closing Cash Consideration shall be reduced by an amount equal to the
Allocated Value of the affected Subject Interest and the Carried Cost Obligation shall be reduced by an amount equal to the Allocated Carry for the affected Subject Interest; or 

 

 49 








 (D) to the extent attributable to the Subject Interests, have EXCO indemnify and hold
harmless the BG Indemnified Parties 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 (A), (B), (C) or (D) above with respect to any
Pre-Closing Environmental Defect, they shall be deemed to have elected alternative (A), provided that if the existence of the Pre-Closing Environmental Defect or the Remediation Amount is disputed, no reduction shall be made in the Closing Cash
Consideration pursuant to Section 3.3(b)(v) 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 (A) above, then from and after the Closing, BG and its Affiliates (other than Midstream LLC and Operator) shall be responsible and pay for 50% of the costs and expenses attributable to the Remediation of the
applicable Pre-Closing Environmental Defect (net to the interest of the EXCO Subs in the underlying properties prior to the Closing) and 50% of all Liabilities (net to the interest of the EXCO Subs in the underlying properties prior to the Closing)
with respect thereto. If the Parties elect the option set forth in clause (B) 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 (1) 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 (2) 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. 
 (ii) With respect to any
Post-Closing Environmental Defect that has not been waived in writing by BG, or cured on or before the Post-Closing Environmental Defect Remedy Date, subject to EXCO’s right to dispute the existence of such Environmental Defect and/or the
Remediation Amount asserted with respect thereto and subject to the Individual Environmental Defect Threshold and the Environmental Deductible, the Parties shall mutually elect to: 

(A) subject to the Individual Environmental Defect Threshold and the Environmental Deductible, make a payment from EXCO to BG in an
amount equal to the Remediation Amount of such Environmental Defect; 
 (B) have the applicable Newco reassign to EXCO, with
special warranty of title against claims by, through or under BG, but not otherwise, the Subject Interests, or, at the option of BG, that portion of the Subject Interests pertaining to the Shallow Rights, that are subject to such Environmental
Defect, and the Operator reassign to EXCO, with special warranty of title against claims by, through or under Operator, but not otherwise, the Assets, or, at the option of BG, that portion of the Assets pertaining to the Shallow Rights, that are
subject 
  

 50 








 
to such Environmental Defect, in each case, together with all associated Assets, and, concurrently therewith, EXCO shall pay to BG an amount equal to the Allocated Value of the applicable Subject
Interests, the Carried Cost Obligation shall be reduced by an amount equal to the Allocated Carry for the applicable Subject Interests and such property and assets shall become Excluded Assets hereunder; or 

(C) have EXCO indemnify BG with respect to such Environmental Defect by an indemnity in form and substance satisfactory to BG.

 In the event that the Parties do not agree in writing by the Post-Closing Environmental Defect Remedy Date on an election of alternative (A),
(B) or (C) above with respect to any Post-Closing Environmental Defect, they shall be deemed to have elected alternative (B); provided that if the existence of a Post-Closing Environmental Defect or the Remediation Amount asserted with
respect thereto is disputed, no reassignment shall be made until the dispute is resolved pursuant to Section 12.1(f). 

(d) Exclusive Remedy. Subject to BG’s remedy for a breach of EXCO’s representation contained in
Section 4.15 and BG’s rights under Section 13.1, Section 12.1(c) shall be the exclusive right and remedy of BG with respect to any Environmental Defect. No matter claimed as an Environmental Defect
pursuant to this Article XII may also be claimed as a breach of Section 4.15. 
 (e) Environmental
Deductibles. Notwithstanding anything to the contrary, (i) in no event shall there be any adjustments to the Closing Cash Consideration or other remedies provided by EXCO for any individual Environmental Defect for which the Remediation
Amount does not exceed $25,000 (“Individual Environmental Threshold”), and (ii) in no event shall there be any adjustments to the Closing Cash Consideration or other remedies provided by EXCO for any Environmental Defect for
which the Remediation Amount exceeds the Individual Environmental Threshold pursuant to Section 12.1(c)(i)(A) or Section 12.1(c)(ii)(A) 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 Interests that are subject to Environmental Defects which EXCO: (1) assumes pursuant to
Section 12.1(C)(i)(B); (2) retains pursuant to Section 12.1(c)(i)(C); (3) is conveyed pursuant to Section 12.1(c)(ii)(B); and (4) indemnifies BG pursuant to Section 12.1(c)(i)(D) or
Section 12.1(c)(ii)(C) 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 Consideration only with respect to aggregate
Remediation Amounts in excess of such Environmental Deductible. If the Parties elect to have any Subject Interests related to any Environmental Defect distributed to, and retained by, EXCO, then pursuant to Section 12.1(c)(i)(C), the
Closing Cash Consideration shall be reduced by the Allocated Value of such retained Subject Interests, the Carried Cost Obligation shall be reduced by the Allocated Carry for such retained Subject Interests and the Remediation Amount for the
Environmental Defect relating to such retained Subject Interests will not be counted towards the Environmental Deductible. The Parties agree that if the same Environmental Defect affects more than one Asset, then the Environmental Defect Amounts for
each Asset affected by such Environmental Defect shall be aggregated for the purposes of determining whether the Individual Environmental Defect Threshold has been met with respect to such Environmental Defect. 

 

 51 








 (f) Environmental Dispute Resolution. EXCO and BG shall attempt to agree on all
disputes (i) relating to Pre-Closing Environmental Defects, the Remediation Amounts relating thereto prior to Closing or (ii) relating to Post-Closing Environmental Defects, the Remediation Amounts relating thereto prior to the
Post-Closing Title Remedy Date. If EXCO and BG are unable to agree by such date, the Environmental Defects and/or Remediation Amounts in dispute shall be exclusively and finally resolved by arbitration pursuant to this Section 12.1(f).
There shall be a single arbitrator, who shall be an environmental attorney with at least 10 years experience in environmental matters involving oil and gas producing properties in the regional area in which the affected Subject Interests are
located, as selected by mutual agreement of BG and EXCO within 15 days after the end of the applicable Environmental Cure Period, and absent such agreement, by the Dallas office of the AAA (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 AAA, 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 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 Consideration pursuant to Section 3.5 or Section 3.6 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 Consideration shall not be adjusted
therefor as of the Closing and subsequent adjustments thereto, if any, will be made pursuant to Section 3.6, Section 3.7 or this Section 12.1.  

12.2 NORM, Wastes and Other Substances. BG acknowledges that the Subject Interests have
been used for exploration, development and production of oil and gas and that there may be petroleum, produced water, wastes or other substances or materials located in, on or under the Subject Interests or associated with the Subject Interests.
Equipment and sites included in the Subject Interests may contain asbestos, NORM or other Hazardous Substances. 
  

 52 








 
NORM may affix or attach itself to the inside of wells, materials, and equipment as scale, or in other forms. The wells, materials, and equipment located on the Subject Interests or included in
the Subject Interests 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 Interests. This Section shall not limit BG’s
remedies under the other terms of this Agreement.

13.6 Indemnification Procedures. All claims for indemnification under
Sections 10.1(c), 13.1 and 13.2 shall be asserted and resolved as follows: 
 (a) For purposes of this
Article XIII, 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 XIII, 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 XIII. 
 (b) To make claim for indemnification under Sections 10.1(c),
13.1 or 13.2, an Indemnified Party shall notify the Indemnifying Party of its claim under this Section 13.6, 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 13.6 shall not relieve the Indemnifying Party of its obligations under Sections 10.1(c), 13.1 or 13.2 (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. 
  

 56 








 (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. 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 13.6(d) (provided, however, that the Indemnified Party shall not be required to bring any counterclaim or cross-complaint against any Person). 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). 

(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. 
  

 57 








 13.7 Survival. 

(a) The representations and warranties of the Parties in Articles IV and V (other than the representations and
warranties in Sections 4.1, 4.2, 4.6, 4.16, 4.17, 4.20(a), 4.26, 5.7, 5.8 and 5.9) and the covenants and agreements of the Parties in Sections 6.1, 6.3, 6.4 and 9.4
shall survive the Closing for a period of 18 months. The representations and warranties of EXCO in Sections 4.6 and 4.16 shall survive the Closing for the applicable statute of limitations. Subject to the foregoing and as set forth in

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
13.1(a), 13.1(b), 13.2(a) and 13.2(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
Sections 13.1(d) and 13.1(f) shall survive the Closing for a period of 18 months. EXCO’s indemnities set forth in Sections 13.1(c), 13.1(e), 13.1(g), 13.1(h), 13.1(i) and 13.1(j), and BG’s
indemnities set forth in Section 13.2(c) 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 13.1(a)
through 13.1(j) or Section 13.2(a) through 13.2(c) prior to the date of termination for such indemnity. 

13.8 Non-Compensatory Damages. None of the BG Indemnified Parties nor EXCO Indemnified
Parties shall be entitled to recover from EXCO or BG, 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 EXCO, on behalf of each of EXCO Indemnified Parties, 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. 

13.9 Cooperation by BG Concerning Retained Litigation. BG agrees to use reasonable
efforts to cooperate with EXCO in connection with EXCO’s defense and other actions relating to or arising out of the litigation and claims set forth on Schedule 4.7, Part 1 and Schedule 4.7, Part 2 (provided, however,
that BG shall not be required to bring any claim, counterclaim or cross-complaint against any Person). 
  

 58 








 13.10 Exclusion of Certain Matters.

shall not be subject to this Article XIII (other than Section 13.8 which shall apply in all respects). 

ARTICLE XIV 

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 July 1, 2010 (the
“Termination Date”); 
 (b) by EXCO or BG upon mutual written consent; or 

(c) by EXCO, if EXCO, BG and Escrow Agent have entered into the Escrow Agreement but BG fails to deposit the Deposit with the Escrow
Agent by the Deposit Date pursuant to Section 3.2; 
 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. 
 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, 3.2, 4.17, 5.9, 10.1(c), 10.1(e),
10.2, 10.3, 13.8, this Section 14.3, 14.4 and Article XV (other than Sections 15.2(b), 15.2(c), 15.3, 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 3.2, and elects to retain the Deposit pursuant to Section 3.2, then such retention shall constitute full and complete satisfaction of any and all damages and remedies EXCO may
have against BG under this Agreement for claims and actions arising at or prior to the termination of this Agreement except for EXCO’s remedies under Sections 5.9, 10.1(c), 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. 
  

 59 








 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 Interests 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 XV 

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. 

(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 evidence title to the Assets in a Reorganized Entity shall be allocated to such Reorganized Entity and borne by BG or EXCO, as applicable, in proportion to their ownership interests in such Reorganized
Entity after completing the transactions described in this Agreement. 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 (i) with respect to the transactions described in this Agreement and (ii) with respect to the EXCO Subs, for all periods (or portions thereof) ending on or prior to the Closing Date. BG 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 transfer of Assets to a Reorganized Entity to the extent of its ownership interests in
such Reorganized Entity after completing 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 Interests for
(A) any period ending prior to the Effective Time and (B) any 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 Interests arising on or after the Effective Time (including all Straddle Period Taxes not apportioned to EXCO in
the preceding sentence) 
  

 60 








 
shall be allocated to and borne by BG and EXCO in accordance with their proportionate direct and indirect ownership of the Assets as determined after the transactions contemplated by this
Agreement have been completed. Upon determination of the actual amount of Asset Taxes, EXCO shall pay to BG 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. 
 (c) EXCO shall prepare and timely file any Tax returns of EXCO PA and EXCO WV that are required to be filed for
any period that ends on or before the Closing Date and shall pay any Taxes required to be paid with respect to such Tax Returns. In addition, EXCO shall timely file any return with respect to Asset Taxes due after the Effective Time and 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 BG is
responsible under Section 15.2(b). Within 15 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 (which approval will not be unreasonably withheld or delayed).

 15.3 Tax Treatment. 

(a) The Parties intend and expect that the transactions contemplated by this Agreement and the Joint Development 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, as resulting in (a) the sale to BG by EXCO of 50% of the outstanding
membership interests in Operator and Midstream LLC, which, under Rev. Rul 99-5, 1999-1 C.B. 434, is treated for federal tax purposes as a sale by EXCO of an undivided 50% interest in the assets of Operator and Midstream LLC, followed by the
contribution by each of EXCO and BG of undivided 50% interests in such assets to newly formed partnerships corresponding in legal form to Operator and Midstream LLC; (b) the creation of a partnership (the “Tax Partnership”) in
which the Reorganized Subs, Newcos and Operator are treated as partners, with the Tax Partnership being treated for Tax purposes as holding the Non-Operating Assets and engaging in all activities of the Parties with respect to the Non-Operating
Assets and other similar interests in oil and gas properties that may be acquired by the Parties pursuant to the Joint Development Agreement, (c) a contribution to the Tax Partnership by EXCO of 99.5% of the Non-Operating Assets and a
commitment to fund the costs allocable to it under the Joint Development Agreement in exchange for a 49.75% interest therein; (d) a contribution to the Tax Partnership by Operator of 0.5% of the Non-Operating Assets and a commitment to fund the
costs allocable to it under the Joint Development Agreement in exchange for a 0.5% interest therein; (e) a contribution to the Tax Partnership of the Newco Consideration, as adjusted, and a commitment to fund the costs allocable to it under the
Joint Development Agreement to the Tax Partnership by BG in exchange for a 49.75% interest therein; (f) a distribution to EXCO of the Newco Consideration, as adjusted (i) as a reimbursement of EXCO’s “preformation
expenditures” with respect to the Non-Operating Assets referred to in clause (c) above, as such term is used in 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, of such Non-Operating Assets to the Tax Partnership to the extent Treasury Regulations Section 1.707-4(d) is
inapplicable; and (g) the realization by the Tax Partnership of all items of income or gain and the incurrence by the Tax 

 

 61 








 
Partnership of all items of costs or expenses attributable to the ownership, operation or disposition of the Non-Operating Assets and other similar interests in oil and gas properties that may be
acquired by the Parties pursuant to the Joint Development Agreement, notwithstanding that such items are realized, paid or incurred by the Parties individually, all as set forth in the Tax Partnership Agreement attached as Exhibit “G” to
the Joint Development Agreement. 
 (b) The Parties further intend and expect that the Tax Partnership Agreement will use the
remedial allocation method under Treasury Regulations Section 1.704-3(d) in order to enable BG to realize tax benefits in the same amount and at the same rate and character as if BG had purchased its share of Tax Partnership’s assets as an
outright asset purchase outside of a tax partnership arrangement. 
 15.4 Allocation of
Consideration for Tax Purposes. EXCO and BG agree that the Closing Cash Consideration, as adjusted, shall be allocated among the Transaction Components, and within each Transaction Component to the costs covered thereby that are treated for
federal Tax purposed, in whole or in part, as being the subject of a sale transaction (collectively, the “Allocable Amounts”). The initial draft of such allocations shall be prepared in a manner consistent with the Allocated Values
by EXCO and shall be provided to BG concurrently with the delivery of the Final Settlement Statement. EXCO and BG shall then cooperate to prepare a final schedule of the Allocable Amounts, which shall also be materially consistent with the Allocated
Values (as adjusted, the “Allocation Schedule”). The Allocation Schedule shall be updated to reflect any adjustments to Allocable Amounts. The allocation of the Allocable Amounts shall be reflected on completed Internal Revenue
Service Forms 8594 (Asset Acquisition Statement under Section 1060), which Forms will be timely filed separately by EXCO and BG (and/or the Tax Partnership, as appropriate) with the Internal Revenue Service pursuant to the requirements of
Section 1060(b) of the Code. Each Party agrees not to (and to cause the Tax Partnership not to) take any position inconsistent with the allocations set forth in the Allocation Schedule unless required by applicable Law or with the consent of
the other Party. The Parties further agree that the allocations set forth on the Allocation Schedule will represent reasonable estimates of the fair market values of the assets described therein. In the event that EXCO and BG cannot agree on a
mutually satisfactory Allocation Schedule within 30 days of the finalization of the Final Settlement Statement pursuant to Section 3.6, such dispute shall be resolved in a manner similar to that described in Section 3.7.

 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.

 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. 

 

 62 








 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

consult with each other, and each shall promptly pay its 
  

 64

with the foregoing covenant. 
 15.10 Filings, Notices and Certain Governmental

(d) file the Reorganization Certificate of Merger and any other certificate required by any Governmental Authority in connection with the Reorganization in all counties where the Assets are located. All costs of the foregoing shall be borne in
equal shares by the Parties. 
 15.11 Entire Agreement; Conflicts. THIS AGREEMENT, THE
EXHIBITS HERETO, THE TRANSACTION DOCUMENTS AND THE CONFIDENTIALITY AGREEMENT COLLECTIVELY CONSTITUTE THE ENTIRE AGREEMENT AMONG EXCO AND BG PERTAINING TO THE SUBJECT MATTER HEREOF AND SUPERSEDE ALL PRIOR AGREEMENTS, UNDERSTANDINGS, NEGOTIATIONS, AND
DISCUSSIONS, WHETHER ORAL OR WRITTEN, OF THE PARTIES PERTAINING TO THE SUBJECT MATTER HEREOF. THERE ARE NO WARRANTIES, REPRESENTATIONS, OR OTHER AGREEMENTS AMONG THE PARTIES RELATING TO THE SUBJECT MATTER HEREOF EXCEPT AS SPECIFICALLY SET FORTH IN
THIS AGREEMENT, AND NEITHER EXCO NOR BG SHALL BE BOUND BY OR LIABLE FOR ANY ALLEGED REPRESENTATION, PROMISE, INDUCEMENT, OR STATEMENTS OF INTENTION NOT SO SET FORTH. IN THE EVENT OF A CONFLICT BETWEEN THE TERMS AND PROVISIONS OF THIS AGREEMENT AND

 15.14
Waiver; Rights Cumulative. Any of the terms, covenants, representations, warranties, or conditions hereof may be waived only by a written instrument executed by or on behalf of the Party waiving compliance. No course of
dealing on the part of EXCO or BG, or their respective officers, employees, agents, or representatives, nor any failure by EXCO or BG to exercise any of its rights under this Agreement shall operate as a waiver thereof or affect in any way the right
of such Party at a later time to enforce the performance of such provision. No waiver by any Party of any condition, or any breach of any term, covenant, representation, or warranty contained in this Agreement, in any one or more instances, shall be
deemed to be or construed as a further or continuing waiver of any such condition or breach or a waiver of any other condition or of any breach of any other term, covenant, representation, or warranty. The rights of EXCO and BG under this Agreement
shall be cumulative, and the exercise or partial exercise of any such right shall not preclude the exercise of any other right. 

15.15 Governing Law; Jurisdiction; Venue; Jury Waiver. THIS AGREEMENT AND THE
LEGAL RELATIONS AMONG THE PARTIES SHALL BE GOVERNED AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS, EXCLUDING ANY CONFLICTS OF LAW RULE OR PRINCIPLE THAT MIGHT REFER CONSTRUCTION OF SUCH PROVISIONS TO THE LAWS OF ANOTHER
JURISDICTION. SUBJECT TO SECTION 15.16, ALL OF THE PARTIES HERETO CONSENT TO THE EXERCISE OF JURISDICTION IN PERSONAM BY THE COURTS OF THE STATE OF TEXAS FOR ANY DISPUTE. EACH PARTY HERETO WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE

 15.16
Arbitration. 
 (a) Except for matters that are subject to the dispute resolution procedures set forth in
Sections 3.7, 11.2(j) and 12.1(f) and for the matters set forth in Section 10.2, any Dispute among 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 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 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 

 

 66 








 
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 for U.S. dollar deposits (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. 
  

 67 








 (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.
