existing under the Laws of Texas (“EPC”), and EXCO Operating Company, LP, a limited partnership organized and existing under the Laws of the State of Delaware (“EOC” and together with EPC, “EXCO”).
BG and EXCO shall sometimes be referred to herein together as the “Parties”, and individually as a “Party”. The Parties shall sometimes be referred to herein together in their capacities as working interest owners
in the Subject Oil and Gas Assets as the “Development Parties”, and individually as a “Development Party”. Capitalized terms used herein and not otherwise defined shall have the meanings given such terms in Appendix
I. 
 RECITALS 
 WHEREAS,
on the Closing Date, BG and EXCO consummated certain transactions contemplated in the Purchase Agreement, which transactions included the purchase by BG and the sale by EXCO of undivided interests in certain Oil and Gas Assets; and 
 WHEREAS, the Development Parties desire to develop the Subject Oil and Gas Assets located in the East Texas/North Louisiana Area in a coordinated manner
using EXCO Operator as operator; and 
 WHEREAS, the Parties now desire to set forth their respective rights and obligations with respect to
all such arrangements. 
 NOW THEREFORE, IN CONSIDERATION OF THE MUTUAL AGREEMENTS HEREIN CONTAINED, THE PARTIES HEREBY AGREE AS FOLLOWS:

 ARTICLE 1 
 INTERPRETATION 
 All references in this Agreement to Exhibits, Appendices, Articles, Sections, subsections and other
subdivisions refer to the corresponding Exhibits, Appendices, Articles, Sections, subsections and other subdivisions of or to this Agreement unless expressly provided otherwise. Titles appearing at the beginning of any Articles, Sections,
subsections and other subdivisions of this Agreement are for convenience only, do not constitute any part of this Agreement, and shall be disregarded in construing the language hereof. The words “this Agreement,” “herein,”
“hereby,” “hereunder” and “hereof,” and words of similar import, refer to this Agreement as a whole and not to any particular Article, Section, subsection or other subdivision unless expressly so limited. The words
“this Article,” “this Section,” and “this subsection,” and words of similar import, refer only to Article, Section or subsection hereof in which such words occur. The word “including” (in its various forms)
means including without limitation. All references to “$” or “dollars” shall be deemed references to United States dollars. Each accounting term not defined herein will have the meaning given to it under GAAP as interpreted as of
the date of this Agreement. Pronouns in masculine, feminine or neuter genders shall be construed to state and include any other gender, and words, terms and titles (including terms defined herein) in the

singular form shall be construed to include the plural and vice versa, unless the context otherwise requires. Appendices and Exhibits referred to herein are
attached to and by this reference incorporated herein for all purposes. References to any Law or agreement shall mean such Law or agreement as it may be amended from time to time. 
 ARTICLE 2 
 CERTAIN OBLIGATIONS 
 Section 2.1 Carry of Eligible Costs. 
  

	 	(a)	From and after the Closing Date and until the Carry Termination Event, and notwithstanding the terms of any Applicable Operating Agreement to the contrary, BG shall pay seventy-five
percent (75%) of EXCO’s share under each Applicable Operating Agreement of all Eligible Costs incurred in accordance with an approved Annual Work Program and Budget or pursuant to a Sole Risk Development Operation undertaken by EXCO with
respect to the Deep Rights (all such Eligible Costs that BG is obligated to pay pursuant to this Section 2.1, “Carried Costs”). As used herein, “Carry Termination Event” means the time at which the aggregate
amount of Carried Costs paid by BG equals the Carried Cost Obligation. Joint Development Operator shall maintain an accurate record of the Carried Costs paid by BG from time to time, and shall provide each Development Party with a monthly statement
showing the Calendar Month and inception to date payments by BG. 

  

	 	(b)	Until the Carry Termination Event, all Carried Costs shall be paid by BG in the same manner and at the same time it pays its share of billings or requests for advances pursuant to
Section 2.2. BG shall be entitled to exercise all rights available to the parties under the Applicable Operating Agreements to contest charges and audit the accounts of the operator thereunder with respect to such payments. Any reimbursements
for any Carried Costs paid by BG shall be paid by EXCO or the applicable reimbursing party to BG promptly after the determination thereof (and, to the extent reimbursable by Person other than EXCO and paid to EXCO, receipt by EXCO of such amounts),
provided that any amounts so reimbursed to BG shall be deducted from the calculation of the Carried Costs paid by BG for purposes of this Agreement, including the determination of the Carry Termination Event. In the event EXCO receives a credit in
respect of Carried Costs paid by BG, at the request of BG, EXCO shall request that such credit be paid directly to BG (and any such credit actually paid to BG shall be deducted from the calculation of Carried Costs paid by BG pursuant to this
Agreement). 

 Section 2.2 Payment Procedure. 
  

	 	(a)	In response to each statement or invoice issued by an operator to the Participating Parties in a Development Operation under this Agreement or an Applicable Operating Agreement,
each Participating Party shall pay its share of expenditures for the conduct of such Development Operations in accordance with the escrow provisions set forth in Exhibit “H” attached hereto. 

  

 2 









	 	(b)	Each Participating Party shall have the right to audit the Joint Development Operator’s and its Affiliates’ accounts with respect to Development Operations in which it
participates or is a non-consenting party on the same basis as is provided in Exhibit “C” to the Joint Development Operating Agreement. 

 Section 2.3 Development Costs. Except as set forth in Section 2.1 above, each Development Party shall bear and pay its proportionate share of all Development Costs incurred from and after the
Closing Date in accordance with, and subject to, the terms and conditions of this Agreement and the Applicable Operating Agreements. 
 ARTICLE 3

Development Parties shall be revised accordingly. 

 Section 3.3 Operations Subject to Laws, Leases and Operating
Agreement. All operations conducted pursuant to this Agreement by Joint Development Operator or any Applicable Operating Agreement by any Party Operator shall be conducted in compliance with 
  

 3 








 
the terms and conditions of: (a) all applicable Laws; (b) those Leases upon which such operations are conducted; (c) the Applicable Operating
Agreements, to the extent applicable to such operations; and (d) once agreed in accordance with Section 4.10, appropriate HSSE guidelines and principles. Joint Development Operator, while conducting operations under this Agreement, and any
Party Operator, while conducting operations under any Applicable Operating Agreement, shall conduct such activities as a reasonably prudent operator, in a good and workmanlike manner with due diligence and dispatch, in accordance with good oilfield
practice and appropriate technical standards and guidelines issued by the American Petroleum Institute, the American Society of Mechanical Engineers and the American National Standards Institute, among others. Within twelve months of signing this
Agreement, the Development Parties shall perform a gap analysis against a set of agreed technical standards for design, construction and operation of the wells and facilities within the East Texas/North Louisiana Area. These standards shall be
submitted to the Operating Committee for its approval and shall include appropriate technical standards and guidelines (as mentioned above), including agreed exceptions, and shall adhere to HSSE guidelines and principles agreed upon pursuant to
Section 4.10. 
 Section 3.4 Operating Agreements. 
  

	 	(a)	All Leases in the East Texas/North Louisiana Area: (i) in which only the Development Parties hold interests as of the Effective Date and which are not subject to a Third Party
Operating Agreement; or (ii) in which the Development Parties hereafter acquire interests and which are not subject to a Third Party Operating Agreement at the time of acquisition shall be deemed to be subject to and governed by an operating
agreement in the form attached hereto as Exhibit “B” (each a “Joint Development Operating Agreement”). 

  

	 	(b)	In addition, the Parties agree to use all commercially reasonable efforts to have the form attached hereto as Exhibit “B” adopted as the operative operating agreement by
all working interest owners for any Leases in the East Texas/North Louisiana Area in which the Development Parties and other Persons hold working interests but which are not presently subject to a Third Party Operating Agreement.


  

	 	(c)	A separate Joint Development Operating Agreement shall be deemed to cover each drilling and production unit now or hereafter designated by the Parties or by order or rule of a
Governmental Authority having jurisdiction in the East Texas/North Louisiana Area for which the Development Parties hold the entirety of the working interest for such unit, provided that in the event any Person that is not a Development Party is to
acquire a working interest in such unit or this Agreement terminates, the Development Parties shall execute a Joint Development Operating Agreement for such unit prior to such acquisition or termination. 

  

 4 









	 	(d)	There shall be no retroactive adjustment of expenses incurred or revenues received with respect to any separate Joint Development Operating Agreement which is deemed to come into
existence as a consequence of the designation of a new unit. 

  

	 	(e)	Each Joint Development Operating Agreement in which no third party participates and, as between the Parties only, each Joint Development Operating Agreement in which a third party
participates and each Third Party Operating Agreement, shall be subject to the provisions of Exhibit G hereto unless and until the applicability of such provisions to the Subject Oil and Gas Assets subject to such operating agreement terminates in
accordance with the terms of Exhibit G. 

 Section 3.5 Appointment and Removal of Party Operator.

  

	 	(a)	EXCO Operator is hereby designated and agrees to serve as the initial operator under each Joint Development Operating Agreement and to operate the Subject Oil and Gas Assets covered
by such Joint Development Operating Agreement in accordance with the terms and conditions thereof, subject (in each case) to the terms of this Agreement. To the extent EOC or EPC serves as operator under any Third Party Operating Agreement, such
Person is hereby designated and agrees to serve as operator under such Third Party Operating Agreement and to operate the Subject Oil and Gas Assets covered by such Third Party Operating Agreement in accordance with the terms and conditions thereof,
subject (in each case) to the terms of this Agreement. The designations set forth in this Section 3.5(a) are personal to the applicable EXCO Operator, as a consequence of the specific skills it holds with respect to shale operations, and
operations in the Haynesville shale in particular. For the avoidance of doubt, a Party Operator shall conduct each Sole Risk Development Operation conducted pursuant to the Joint Development Operating Agreement for which it is operator on behalf of
all of the parties participating in such operation, unless otherwise agreed by such participating parties in accordance with the terms of such Joint Development Operating Agreement. 

  

	 	(b)	A Party Operator may be removed as operator under any Joint Development Operating Agreement, or if any Person that is not a Development Party is party to such Joint Development
Operating Agreement, then a Party Operator may be required to resign as operator under such Joint Development Operating Agreement, under the following circumstances: 

 (i) by the affirmative vote of the Development Parties that are parties to such Joint Development Operating Agreement, other than Party
Operator and its Affiliates, holding a majority of the Participating Interest held by such Development Parties: (A) if there is a Change in Control of such Party Operator; or (B) for good cause, provided that in the case of removal or a
required resignation for good cause, such vote shall not be deemed effective until a written notice has been delivered to such Party Operator by another 

  

 5 








 
Party that is a party to such Joint Development Operating Agreement detailing the alleged default and such Party Operator has failed to cure the default
within thirty (30) days from its receipt of the notice or, if the default concerns an operation then being conducted, within forty-eight (48) hours of its receipt of the notice; 
 (ii) by the affirmative vote of the Development Parties that are parties to such Joint Development Operating Agreement holding a majority
of the Participating Interest in the event that Party Operator’s and its Affiliates’ aggregate Participating Interest falls below twelve and a half percent (12.5%); or 
 (iii) solely with respect to those After Acquired Units for which EXCO or any Affiliate of EXCO serves as Party Operator under the
relevant Joint Development Operating Agreement, upon a change in Control of the ultimate parent company of EXCO. 
 For purposes hereof, “good
cause” shall mean not only gross negligence and willful misconduct, but also the material breach of or inability to meet the standards of operation contained in Section 3.3, or a material failure or inability of a Party Operator to perform
its obligations under the relevant Joint Development Operating Agreement. As used herein, “gross negligence” and “willful misconduct” shall include material unlawful acts committed by an operator of which such operator had actual
knowledge at the time in question. Notwithstanding anything to the contrary herein, (I) if there is a dispute as to whether a condition resulting in good cause to remove a Party Operator has occurred, or whether such condition has been cured,
such Party Operator shall continue to serve and discharge its duties in such capacity until the dispute has been resolved in accordance with Section 13.2, and (II) a change of a corporate name or structure of a Party Operator or Transfer of a
Party Operator’s interest to another direct or indirect Wholly-Owned Affiliate of the same ultimate parent company shall not be the basis for removal of such Party Operator. 
 During the term of this Agreement, for avoidance of doubt, as between the Parties, the provisions of this Section 3.5(b) and Section 3.5(c) shall be in lieu of any provisions in any Joint Development
Operating Agreement for the removal or resignation of the operator thereunder. 
  

	 	(c)	Upon the occurrence of a Material Event with respect to a Party Operator, it shall be deemed to have resigned as operator under each Joint Development Operating Agreement for which
it serves as operator, or if any Person that is not a Development Party is party to such Joint Development Operating Agreement, then a Party Operator shall be required to resign as operator under such Joint Development Operating Agreement, without
any action by the other Parties, except the selection of a successor pursuant to the terms and conditions of the relevant Joint Development Operating Agreement. 

  

	 	(d)	Following any resignation or removal of EXCO Operator as operator under any Applicable Operating Agreement, if BG or one of its Affiliates is still a Party to this Agreement, EXCO
shall vote for BG or BG’s designee to serve as the successor operator under such Applicable Operating Agreement. 

  

 6 









	 	(e)	Each Party Operator shall conduct all operations in accordance with and subject to the terms of Article 4, and Sections 3.3, 3.4, this 3.5, 3.7, 3.10 and 3.11, in addition to any
terms set forth in the relevant Applicable Operating Agreements. 

 Section 3.6 Joint Development Operator.

  

	 	(a)	EOC is hereby designated and agrees to serve as the initial Joint Development Operator in accordance with the terms and conditions of this Agreement. The designation set forth in
this Section 3.6(a) is personal to EOC, as a consequence of the specific skills it holds with respect to shale operations, and operations in the Haynesville shale in particular. 

  

	 	(b)	Joint Development Operator may resign at any time by giving at least ninety (90) days’ prior written notice to the other Development Parties. Joint Development Operator
shall be deemed to have resigned without any action by the other Development Parties, except for selection of a successor, under the following circumstances: (i) Joint Development Operator terminates its legal existence (other than as part of a
reorganization that results in the Transfer of all of its rights and obligations in the East Texas/North Louisiana Area to a Wholly-Owned Affiliate of the same ultimate parent company of such Joint Development Operator); (ii) Joint Development
Operator no longer possesses the corporate capability to serve as Joint Development Operator (provided that, for the avoidance of doubt, corporate capability is not a measure of Joint Development Operator’s knowledge and expertise regarding the
performance of drilling operations, but instead concerns Joint Development Operator’s ability to function as a business generally); or (iii) any payment default or acceleration of debt (other than an acceleration of debt caused by a Change
in Control of Joint Development Operator or any of its Affiliates) by Joint Development Operator or any of its Affiliates shall have occurred and be continuing under (in each case) any material (I) agreement for borrowed money of Joint
Development Operator or any of its Affiliates or (II) guarantee by Joint Development Operator or its Affiliates of another Person’s payment or performance obligations. 

  

	 	(c)	Joint Development Operator may be removed under the following circumstances: 

 (i) by the affirmative vote of the Development Parties other than Joint Development Operator and its Affiliates holding a majority of the
Participating Interest held by such Development Parties: (A) if there is a Change in Control of Joint Development Operator; or (B) for good cause, provided that in the case of removal for good cause, such vote shall not be deemed effective
until a written notice has been delivered to Joint Development Operator by another Party detailing the alleged default and Joint Development Operator has failed to cure the default within thirty (30) days from its receipt of the notice or, if
the default concerns an operation then being conducted, within forty-eight (48) hours of its receipt of the notice; or 
  

 7 








 (ii) by the affirmative vote of the Development Parties holding a majority of the
Participating Interest in the event that Joint Development Operator’s and its Affiliates’ aggregate Participating Interest falls below twelve and a half percent (12.5%). 
 For purposes hereof, “good cause” shall mean not only gross negligence or willful misconduct but also the material breach of or inability to meet the standards of operation contained in
Section 3.3, or material failure or inability to perform its obligations under this Agreement. Notwithstanding anything to the contrary herein, (I) if there is a dispute as to whether a condition resulting in good cause to remove Joint
Development Operator has occurred, or whether such condition has been cured, Joint Development Operator shall continue to serve and discharge its duties in such capacity until the dispute has been resolved in accordance with Section 13.2, and
(II) a change of a corporate name or structure of Joint Development Operator or Transfer of Joint Development Operator’s interest to another direct or indirect Wholly-Owned Affiliate of the same ultimate parent company shall not be the basis
for removal of Joint Development Operator. 
  

	 	(d)	Upon the occurrence of a Material Event with respect to Joint Development Operator, it shall be deemed to have resigned without any action by the other Parties, except the selection
of a successor pursuant to Section 3.6(e). If a petition for relief under the federal bankruptcy laws is filed by or against Joint Development Operator, and the removal of Joint Development Operator is prevented by the terms of the Bankruptcy
Code or actions of the federal bankruptcy court, then, to the extent allowed by Law, the Operating Committee shall serve as Joint Development Operator until Joint Development Operator has elected to reject or assume this Agreement pursuant to the
Bankruptcy Code, and an election to reject this Agreement by Joint Development Operator as a debtor in possession, or by a trustee in bankruptcy, shall be deemed a resignation as Joint Development Operator without any action by the other Parties,
except the selection of a successor. 

  

	 	(e)	 Following any resignation or removal of EOC as Joint Development Operator, if BG or one of its Affiliates is still a Party to this Agreement, BG or its designated
Affiliate shall be entitled to become successor Joint Development Operator. Should BG and its Affiliates elect not to become successor Joint Development Operator, or should none of BG and its Affiliates be a Party to this Agreement, a successor
Joint Development Operator shall be selected by the Parties by the affirmative vote of Parties holding collectively at least seventy-five percent (75%) of the Participating Interests eligible to vote. If Joint Development Operator has been
removed for cause or is deemed to have resigned or votes only to succeed itself, it and its Affiliates shall not be entitled to vote for the successor Joint Development Operator (but any transferee of all or any part of the Joint Development
Operator’s Participating Interest shall be entitled to vote for the successor Joint Development Operator). The Joint Development Operator’s resignation or removal shall not become effective until 7:00 o’clock am on the first day of
the Calendar Month following the expiration of ninety (90) days after the giving of notice of resignation by the Joint Development Operator, the 



  

 8 









	 	 
deemed resignation of the Joint Development Operator or action by BG or the non-operators to remove Joint Development Operator, unless a successor Joint
Development Operator has been selected and assumes the duties of Joint Development Operator at an earlier date. 


  

	 	(f)	Subject to the terms and conditions of this Agreement, in addition to those certain other duties and responsibilities expressly set forth herein, Joint Development Operator shall:


 (i) notwithstanding the terms of any Applicable Operating Agreement to the contrary, at the option of any
Development Party, pay such Development Party’s share of: (A) rentals, shut-in well payments and minimum royalties required to be paid to lessees under the Leases included in the Subject Oil and Gas Assets; and (B) royalties,
overriding royalties and other burdens required to be paid to lessees and holders of overriding royalties and other burdens on the Leases included in the Subject Oil and Gas Assets, provided that the Development Party’s share of the payments
described in clauses (A) and (B) shall be billed to or advanced by, as the case may be, such Development Party in accordance with Section 2.2; 
 (ii) at the option of any Development Party, pay such Development Party’s share of joint interest billings and cash calls
(including, in the case of BG, Carried Costs) from third party operators relating to wells in the East Texas/North Louisiana Area not operated by a Party Operator, provided that the Development Party’s share of such payments shall be billed to
or advanced by, as the case may be, such Development Party in accordance with Section 2.2; and 
 (iii) notwithstanding
the terms of any Applicable Operating Agreement to the contrary, at the option of any Development Party, at such Development Party’s expense, secure any title curative matters and pooling amendments or agreements required of such Development
Party under the Applicable Operating Agreement in connection with Leases or other rights to oil and gas included in the Subject Oil and Gas Assets, provided that the Development Party’s expenses for such requested actions shall be billed to or
advanced by, as the case may be, such Development Party in accordance with Section 2.2. 
 Section 3.7 Liability of
Operator. 
  

	 	(a)	 Subject to the rights of a Development Party to remove any Party acting as Joint Development Operator under this Agreement or Party Operator under any Applicable
Operating Agreement in accordance with the terms hereof, in no event shall any Party serving as Joint Development Operator or a Party Operator have any liability as Joint Development Operator under this Agreement or Party Operator under any
Applicable Operating Agreement for any claim, damage, loss or liability sustained or incurred in connection with any Development Operation or any breach of Section 3.3 or any similar provision regarding the standard of performance of a Party
Operator in performing operations under any Applicable

Party exceeds such Development Party’s Working Interest share of the Section 3.12 Overhead Rates for such Development Party for such Calendar Month (such Development Party’s “Actual Operating Agreement Charges”), then
such Party Operator shall credit to such Development Party the difference between its Working Interest share of the Other Overhead Rates paid by such Development Party and its Actual Operating Agreement Charges for such Calendar Month; or

  

 15 








 (ii) to the extent that a Development Party’s Working Interest share of such Other Overhead Rates
in any Calendar Month paid by such Development Party is less than the Actual Operating Agreement Charges for such Development Party for such Calendar Month, then (upon notice by such Party Operator) such Development Party shall pay such Party
Operator the difference between its Actual Operating Agreement Charges and its Working Interest share of such Other Overhead Rates for such Calendar Month in accordance with Section 2.2. 
  

	 	(g)	Each Development Party shall bear its Participating Interest share of the Technical Services Costs and its Working Interest share of overhead rates chargeable to each Development
Party pursuant to this Section 3.12; provided that, in the case of Sole Risk Operations, the costs and expenses of such overhead shall be chargeable solely to the Participating Parties with respect to such Sole Risk Development Operations in

Each Development Party shall appoint one (1) representative and one (1) alternate representative to serve on the Operating Committee, and shall appoint its initial representative and alternate representative by notice to the others on or
prior to the first to occur of the first meeting of the Operating Committee or the first vote of the Operating Committee pursuant to Section 4.1(n). All actions of a Development Party taken with respect to the Operating Committee shall be taken
through its representative or alternate representative. 

  

	 	(b)	Each Development Party shall have the right to change its representative and alternate at any time by giving notice of such change to the other Parties.

	 	(d)	The representative of a Development Party, or in his absence his alternate representative, shall be authorized to represent and bind such Development Party with respect to any
matter which is within the powers of the Operating Committee and is properly brought before the Operating Committee. Each such representative shall have a vote equal to the Participating Interest of the Development Party that appointed such
representative. Each alternate representative shall be entitled to attend all Operating Committee meetings but shall have no vote at such meetings except in the absence of the representative for whom he is the alternate. In addition to the
representative and alternate representative, each Development Party may also bring to any Operating Committee meetings such advisors as it may deem appropriate. 

  

	 	(e)	Joint Development Operator may call a meeting of the Operating Committee by giving notice to the Development Parties at least fifteen (15) days in advance of such meeting. Any
Development Party may request a meeting of the Operating Committee by giving notice to the other Development Parties and Joint Development Operator, which notice shall include any proposals being proposed by such Development Party for consideration
at the meeting (including appropriate supporting information not previously distributed to the Development Parties). Upon receiving such request, Joint Development Operator shall call such meeting for a date not less than fifteen (15) days nor
more than twenty (20) days after receipt of the request. 

  

	 	(f)	The Operating Committee may establish such subcommittees as the Operating Committee may deem appropriate. The functions of such subcommittees shall be to serve in an advisory
capacity only. Each Development Party shall have the right to appoint a representative to each subcommittee. The Operating Committee is hereby deemed to have established an implementation committee whose purpose shall be to brainstorm, develop and
discuss strategies for the efficient development of the Subject Oil and Gas Assets, implementation of such strategies through the Development Work Program and Annual Work Program and Budgets, and potential acquisitions (whether by leasing, purchase,
farm-in or otherwise) of other Oil and Gas Assets (provided that, for the avoidance of doubt, no Development Party or Affiliate of a Development Party shall have any obligation to offer another Development Party the opportunity to participate in
acquisitions of Oil and Gas Assets except as provided in Article 9). 

  

	 	(g)	 Each notice of a meeting of the Operating Committee as provided by Joint Development Operator shall contain: (i) the date, time and location of the meeting;
(ii) an agenda of the matters and proposals to be considered and/or voted upon; and (iii) copies of all proposals to be considered at the meeting (including

appropriate supporting information not previously distributed to the Development Parties). A Development Party, by notice to the other Development Parties
and Joint Development Operator, which notice shall include any additional proposals being proposed by such Development Party to be considered at the meeting (including appropriate supporting information not previously distributed to the Development
Parties), given not less than five (5) Business Days prior to a meeting, may add additional matters to the agenda for a meeting. On the request of a Development Party, and with the unanimous consent of all Development Parties, the Operating
Committee may consider at a meeting a proposal not contained in such meeting agenda. 


  

	 	(h)	There shall be at least one (1) but not more than three (3) meetings of the Operating Committee per Calendar Quarter unless all Development Parties agree in writing to the
contrary. The restriction on number of meetings contained in this Section shall not restrict the number of proposals that may be submitted without a meeting pursuant to Section 4.1(m). Meetings of each subcommittee shall take place as often as
the Operating Committee shall determine. All meetings of the Operating Committee and each subcommittee shall be held in the offices of Joint Development Operator, or elsewhere as the Operating Committee or such subcommittee may mutually decide.


  

	 	(i)	Except as provided otherwise in this Section 4.1(i) and in Section 5.2, all decisions, approvals and other actions of the Operating Committee on all proposals coming
before it that are within its powers to approve or disapprove, shall be decided by the affirmative vote of Development Parties holding collectively at least seventy-five percent (75%) of the Participating Interests of the Development Parties
entitled to vote on such proposals, provided that (i) any Development Operation proposed to the Operating Committee that is not approved by the Operating Committee and that may be proposed and conducted as a Sole Risk Development Operation
under the terms of the Applicable Operating Agreement may be so proposed and conducted by the Development Parties desiring to participate in such Development Operation and (ii) any Area-Wide Operation proposed to the Operating Committee which
is not approved by the Operating Committee may be conducted by those Development Parties desiring to participate in such Development Operation at their sole risk and expense. Notwithstanding the preceding, any proposal to reduce the quantity of work
to be conducted under the Development Work Program or any Annual Work Program and Budget (to the extent relating to any Development Operations included in any Development Work Program) with respect to any period prior to the Carry Termination Event
shall also require the affirmative vote of EXCO.

the agenda; (ii) organization and conduct of the meeting; and (iii) preparation of a written record or minutes of each meeting. 

  

 18 









	 	(k)	Joint Development Operator shall have the right to appoint the chairman of the Operating Committee and each subcommittee, provided that, for the avoidance of doubt, the chairman

each Operating Committee meeting. Each Development Party shall sign and be provided a copy of such record at the end of such meeting, and it shall be considered the final record of the decisions of the Operating Committee. 


 

	 	(l)	The secretary shall provide each Development Party with a copy of the minutes of each Operating Committee meeting within fifteen (15) Business Days after the end of the
meeting. Each Development Party shall have fifteen (15) days after receipt of such minutes to give notice to the secretary of any objections to the minutes. A failure to give notice specifying objection to such minutes within said fifteen
(15) day period shall be deemed to be approval of such minutes. In any event, the votes recorded under Section 4.1(j) shall take precedence over the minutes described above. 

  

	 	(m)	 In lieu of a meeting, any Development Party may submit any proposal that is within the Operating Committee’s powers to approve or disapprove to the Operating
Committee for a vote by notice. The proposing Development Party or Development Parties shall notify Joint Development Operator with written materials describing the proposal and Joint Development Operator shall provide a copy of such proposal to
each Development Party. Any such proposal by a proposing Development Party shall include with such proposal adequate documentation to enable the other Development Parties to make a decision. Each Development Party (including the proposing
Development Party) shall communicate its vote on the proposal by notice to Joint Development Operator and the other Development Parties within fifteen (15) days after receipt of the proposal from the Joint Development Operator, unless such
proposal, together with any other increases to an approved Annual Work Program and Budget for a Calendar Year, if accepted, would result in aggregate spending pursuant to such Annual Work Program and Budget of more than ten percent (10%) in
excess of the original amount of the Annual Work Program and Budget approved pursuant to Section 4.4 (or, in the case of the Annual Work Program and Budget for Calendar Year 2009, attached hereto as Exhibit “E-1”) or, once amended to
increase the amount of the Annual Work Program and Budget ten percent (10%) above the then existing amount in accordance with Section 4.4(e), the amended amount of the Annual Work Program and Budget, in which case each Development Party
(including the proposing Development Party) shall 



  

 19 









	 	 
communicate its vote on the proposal by notice to Joint Development Operator and the other Development Parties within sixty (60) days after receipt of
the proposal from the Joint Development Operator. Any Development Party failing to communicate its vote in a timely manner shall be deemed to have voted against such proposal. Within five (5) Business Days following the expiration of the
relevant time period, Joint Development Operator shall give each Development Party a confirmation notice stating the tabulation and results of the vote on such proposal. 


  

	 	(n)	From time to time, the Operating Committee may approve guidelines, standards or procedures regarding the implementation of Development Operations to be observed in the conduct of
Development Operations by Joint Development Operator and each Party Operator. 

  

	 	(o)	All decisions taken by the Operating Committee pursuant to this Section 4.1 shall be conclusive and binding on all Parties. 

  

	 	(p)	All notices and communications required or permitted to be given under Section 3.10 or Article 4 to the Development Parties or a Party Operator or the members of the Operating

 Section 4.2 Development Work Program.

  

	 	(a)	The Operating Committee shall adopt, and modify from time to time, a multi-year work program for Development Operations (the “Development Work Program”) as follows:


 (i) The Operating Committee is hereby deemed to have approved the work program attached hereto as Exhibit
“D” for Development Operations to be performed through Calendar Year 2012. Such work program shall constitute the Development Work Program applicable through Calendar Year 2012 except as otherwise revised, amended or modified by the
Operating Committee. 
 (ii) On or before August 15 of each Calendar Year, commencing in Calendar Year 2011, Joint
Development Operator shall prepare and submit to the Operating Committee a revised Development Work Program setting forth the Development Operations to be carried out during the following two Calendar Years. Such proposed Development Work Program
shall automatically include any Development Operations which were approved for such period as part of the prior Development Work Program unless the Operating Committee determines to the contrary. Within sixty (60) days after distribution of the
proposed Development Work Program (or such later date as may agreed by the Operating Committee), the Operating Committee shall meet to consider, modify (if necessary) and approve or reject the proposed Development Work Program. If the Operating
Committee does not approve any such Development Work Program on or prior to the first day of the following Calendar Year (for purposes of this Section 4.2(a)(ii), the “current Calendar Year”), then the Development Work Program
for the then-current Calendar Year shall be the Development Work Program, if any, approved for the then-current Calendar Year in the preceding Calendar Year. 
  

	 	(b)	Except as otherwise agreed in writing by the Operating Committee, the Annual Work Program and Budget for each Calendar Year shall contain not less than those Development Operations
to be performed during such Calendar Year as set forth in the Development Work Program. 

 Section 4.3 Initial
Annual Work Plan and Budgets. The Annual Work Program and Budget for the remainder of Calendar Year 2009 is hereby approved by the Operating Committee and is attached hereto as Exhibit “E-1”. The first draft of an Annual Work
Program and Budget for Calendar Year 2010 attached hereto as Exhibit “E-2” is hereby deemed approved by the Operating Committee, provided that the Operating Committee shall approve such further details as would be required under the terms
of Section 4.4 on or before October 15, 2009. 
  

 22 








 Section 4.4 Subsequent Annual Work Plan and Budgets. For each Calendar Year during the
term of this Agreement commencing with Calendar Year 2010, each Annual Work Program and Budget shall be adopted as follows: 
  

	 	(a)	On or before August 15 in the Calendar Year immediately preceding the relevant Calendar Year, Joint Development Operator shall prepare and submit to the Operating Committee a
proposed Annual Work Program and Budget for such applicable Calendar Year (provided that in the case of the proposed Annual Work Program and Budget for Calendar Year 2010, the draft Annual Work Program and Budget attached hereto as Exhibit
“E-2” shall be basis for such proposed Annual Work Program and Budget). Each such proposed Annual Work Program and Budget shall contain at least the following: 

 (i) all Development Operations that are to be conducted during such Calendar Year pursuant to the Development Work Program, except with
the approval of the Operating Committee to the contrary; 
 (ii) all lease maintenance costs and expenditures required under
the terms of existing Leases or existing third party contracts held by Joint Development Operator for the benefit of Joint Development Operations (including each Development Party’s share thereof), except with the approval of the Operating
Committee to the contrary; 
 (iii) estimates of all Technical Services Costs associated with Technical Services to be
provided by Joint Development Operator; 
 (iv) itemized estimates of the Development Costs (including each Development
Party’s share thereof) for Joint Development Operations covered by the proposed Annual Work Program and Budget by budget category and allocated between Shallow Rights and Deep Rights, and Area-Wide Operations, containing sufficient detail (to
the extent available) to afford the ready identification of the nature, scope and duration of the activity in question; 
 (v) the number of wells to be drilled as part of the Joint Development Operations in each of the Shallow Rights and the Deep Rights during such Calendar Year, the proposed locations of such wells (to the extent reasonably ascertainable at
the time such Annual Work Program and Budget is proposed), and the estimated Development Costs (including each Development Party’s share thereof) associated therewith; 
 (vi) estimates of the schedule pursuant to which the Development Parties’ share of Development Costs for Joint Development
Operations included in the Annual Work Program and Budget are anticipated to be incurred by the Development Parties; and 
 (vii) any other information requested in writing by a Development Party that can reasonably be provided by the Joint Development Operator. 
  

 23 









	 	(b)	Itemized expenditures in an Annual Work Program and Budget may extend over more than one Calendar Year because such itemized expenditures represent activities or operations that
require commitments in excess of one Calendar Year. Once itemized expenditures are approved, Joint Development Operator shall not be required to resubmit them for approval of the Operating Committee on an annual or other periodic basis, but instead
all such items shall be automatically included in future Annual Work Program and Budgets as items which have already been approved. 

  

	 	(c)	Joint Development Operator shall regularly consult with the Operating Committee and the implementation subcommittee during the preparation of each proposed Annual Work Program and
Budget. Following receipt of Joint Development Operator’s proposed Annual Work Program and Budget, each Development Party shall furnish to Joint Development Operator and the other Development Parties any comments, suggestions or proposed
amendments it may have respecting the proposed Annual Work Program and Budget as soon as may be reasonably practicable, and Joint Development Operator shall consider and discuss such comments, suggestions and proposed amendments with the Operating
Committee. Unless otherwise extended by the Operating Committee, within sixty (60) days after distribution of the proposed Annual Work Program and Budget for a Calendar Year, the Operating Committee and Joint Development Operator shall meet to
consider, modify (if necessary) and approve or reject the proposed Annual Work Program and Budget. Subject to Section 4.4(d), approval of an Annual Work Program and Budget shall require the approval of the Operating Committee. Inclusion of an
operation in an approved Annual Work Program and Budget or an approved amendment thereof shall, subject to the terms of Section 4.6: (i) bind all Development Parties to participate in such operation, and no Development Party shall have the
right to make any nonconsent election under an Applicable Operating Agreement with respect to such operation; and (ii) authorize Joint Development Operator to conduct such operation for the account of all of the Development Parties under the
relevant Applicable Operating Agreement (provided that, to the extent any third parties are party to such Applicable Operating Agreement, Joint Development Operator shall propose such operation to such third parties in accordance with the terms of
such Applicable Operating Agreement, though, for the avoidance of doubt, Joint Development Operator need not re-propose such operation to the Development Parties), and each Party Operator to conduct such operation, subject to the budgetary
provisions of such Annual Work Program and Budget and Sections 4.4(i) and 4.7, without further authorization from the Operating Committee. Each Development Party agrees to provide such notices, make such elections and take such actions as may
reasonably be required under any Applicable Operating Agreement to implement this provision. For the avoidance of doubt, no Development Party shall be obligated to participate in acquisitions of Leases included in an Annual Work Program and Budget,
but instead shall have the right but not the obligation to participate in such acquisitions pursuant to Article 9. 

  

 24 









	 	(d)	In the event that an Annual Work Program and Budget is not approved on or prior to the first day of the Calendar Year to which such Annual Work Program and Budget pertains (for
purposes of this Section 4.4(d), the “relevant Calendar Year”), the Operating Committee shall be deemed to have approved an Annual Work Program and Budget for such relevant Calendar Year that includes the following:
(i) the Development Operations scheduled to be performed during the relevant Calendar Year as set forth in the Development Work Program, if any, and associated Development Costs reasonably required to implement such Development Operations;
(ii) Operating Expenses equal to the product of the amount of Operating Expenses approved in the preceding Calendar Year’s Annual Work Program and Budget and the Operating Expense Multiplier for the relevant Calendar Year;
(iii) Technical Services Costs equal to the amount of Technical Services Costs approved in the preceding Calendar Year’s Annual Work Program and Budget; (iv) those multi-year expenditures previously approved by the Development Parties
pursuant to Section 4.4(b) that are attributable to the relevant Calendar Year; (v) existing payment commitments to third parties under Leases and contracts binding with respect to the Subject Oil and Gas Assets; and (vi) taxes
payable with respect to the Subject Oil and Gas Assets by any operator under the terms of any Applicable Operating Agreement. 

  

	 	(e)	Any Development Party may propose to amend the Development Work Program or an Annual Work Program and Budget by notice to the Operating Committee and Joint Development Operator.
Approval of any such amendment shall require the approval of the Operating Committee. Notwithstanding any provision of Section 4.1 to the contrary, each Development Party shall have sixty (60) days to consider any proposed amendment that
would increase the estimated costs of the Development Work Program for any Calendar Year or any Annual Work Program and Budget by more than ten percent (10%). To the extent that such amendment is approved by the Operating Committee, the Development
Work Program and relevant Annual Work Program and Budget shall, subject to any required approvals under any Applicable Operating Agreement, be deemed amended accordingly, provided that any such amendment shall not invalidate any commitment or
expenditure already made by an operator under an Applicable Operating Agreement in accordance with any previous authorization given pursuant hereto. 

  

	 	(f)	 Notwithstanding anything to the contrary in this Section 4.4, any Development Party may propose Development Operations that are not included in the Development
Work Program or a then-current approved Annual Work Program and Budget (a “Non-Budgeted Operation”). Any such Non-Budgeted Operation proposed by a Development Party in which all Development Parties agree to participate shall
automatically be added to the Development Work Program and the applicable approved Annual Work Program and Budget(s) and shall cease to be a Non-Budgeted Operation. Any such Non-Budgeted Operation in which less than all of the Development Parties
elect to participate (i) that may be undertaken 



  

 25 









	 	 
as a Sole Risk Development Operation under the terms of the relevant Applicable Operating Agreement or (ii) that is an Area-Wide Operation may be
proposed and conducted as a Sole Risk Development Operation. Notwithstanding the preceding, until December 31, 2012, no Non-Budgeted Operation may be performed as a Sole Risk Development Operation for the benefit of a Development Party if the
sum of the estimated costs of conducting such Non-Budgeted Operation for the account of such Development Party, together with costs incurred or to be incurred by such Development Party with respect to other Sole Risk Development Operations performed
or to be performed in such Calendar Year, together with all Joint Development Operations performed or to be performed in such Calendar Year, exceeds one hundred twenty percent (120%) of the total amount of the approved Annual Work Program and
Budget for such Calendar Year. 


  

	 	(g)	Any Development Operation proposed by a third party pursuant to an Applicable Operating Agreement shall be subject to the terms and conditions of such Applicable Operating
Agreement. Any such Development Operation proposed by a third party in which all Development Parties elect to participate shall automatically be added to the Development Work Program and the applicable approved Annual Work Program and Budget(s). Any
such Development Operation in which less than all of the Development Parties elect to participate that may be undertaken as a Sole Risk Development Operation under the terms of the relevant Applicable Operating Agreement may be so proposed and
conducted. 

  

	 	(h)	Approval by the Operating Committee of an Annual Work Program and Budget shall constitute the Operating Committee’s deemed approval for any Party Operator to expend up to ten
percent (10%) in excess of the authorized amount applicable to its operations within each Annual Work Program and Budget category, not to exceed in the aggregate ten percent (10%) of the aggregate amount applicable to its operations in
such Annual Work Program and Budget, less, in each case, any amounts included as line items for contingencies and overruns with respect to such operations in such category or Annual Work Program and Budget. Each Party Operator shall promptly
notify the Operating Committee of any expenditure made by it in the exercise of its rights pursuant to this Section 4.4(h). The ten percent (10%) deemed approval levels set forth in this Section 4.4(h) shall be calculated with respect
to the original amount of an Annual Work Program and Budget or, once amended, the amended amount of the Annual Work Program and Budget, provided that no expenditures incurred pursuant to Section 4.4(i) shall be deemed to be included in an
approved Annual Work Program and Budget for purposes of calculating the ten percent (10%) deemed approvals pursuant to this Section 4.4(h), nor shall any such expenditures be considered to be amounts expended in excess of the authorized
amount of any Annual Work Program and Budget for purposes of calculating the ten percent (10%) deemed approval levels. 

  

 26 









	 	(i)	Notwithstanding anything to the contrary in this Agreement, any Party Operator is expressly authorized to make expenditures and incur liabilities without prior authorization or
approval when necessary or advisable, in such Party Operator’s good faith judgment, to deal with emergencies, including well blowouts, fires, oil spills, or any other similar event, which may endanger property, lives, or the environment. Each
Party Operator shall as soon as practicable report to the Development Parties the nature of any such emergency which arises, the measures it intends to take in respect of such emergency and the estimated related expenditures.


  

	 	(j)	To the extent reasonably within the control of any Party Operator or the other Development Party or Development Parties conducting any Joint Development Operation, the Joint
Development Operation shall be conducted at the time prescribed in the applicable Annual Work Program and Budget. 

  

	 	(k)	For the avoidance of doubt, any reference in this Agreement to an approved Annual Work Program and Budget shall include an Annual Work Program and Budget that is deemed to have been
approved by the Operating Committee, and shall incorporate all approved amendments thereto and all modifications to Annual Work Program and Budgets described herein that require no action on the part of the Parties. 

 Section 4.5 Statements of Estimated Expenditures. Not later than twenty (20) days prior to the commencement of each
Calendar Quarter during the term of this Agreement, Joint Development Operator shall provide the Development Parties a statement of the estimated Development Costs to be incurred in such Calendar Quarter pursuant to this Agreement, including
Development Costs associated with Joint Development Operations. Such statement shall be for informational purposes only, and, except as otherwise provided in Section 4.6, no approval of the Operating Committee shall be required for any of the
Development Costs identified therein to the extent such Development Costs are included in an approved Annual Work Program and Budget, or are covered by Section 4.4(h). 
 Section 4.6 AFEs. 
  

	 	(a)	Prior to: (i) spudding any well as a Joint Development Operation, (ii) making any material expenditures or incurring any material commitments for work on any Wellbore
Operation to be conducted as a Joint Development Operation that is estimated to cost in excess of five hundred thousand dollars (US$500,000), or (iii) making any material expenditures or incurring any material commitments for work on any
Area-Wide Operation to be conducted as a Joint Development Operation that is estimated to cost in excess of one million dollars (US$1,000,000), the Party Operator or Joint Development Operator, as the case may be, shall submit for the approval of
the Operating Committee an AFE. Where the necessary information is available, such AFE may be submitted and approved for designated wells and Wellbore Operations as part of the proposed Annual Work Program and Budget for a Calendar Year, in which
case no separate subsequent AFE shall be required. 

  

 27 









	 	(b)	Each Development Party shall communicate an Operating Committee vote to approve or reject the AFE within fifteen (15) days following receipt of the AFE (or forty-eight
(48) hours (exclusive of Saturday, Sunday and legal holidays) in the event of a Wellbore Operation when a drilling rig is on location). Any Development Party failing to communicate its vote within the applicable time period shall be deemed to
have voted against the AFE. 

  

	 	(c)	If the Operating Committee approves an AFE for the operation within the applicable period, the Party Operator or Joint Development Operator shall be authorized to conduct the
operation under the terms of this Agreement. If the Operating Committee fails to approve an AFE for the operation within the applicable time period, the operation shall be deemed rejected. The Party Operator or Joint Development Operator shall
promptly notify the Parties if the operation has been rejected, and, subject to Section 4.4(f), any Development Party may thereafter conduct the operation as a Sole Risk Development Operation under the terms of the Applicable Operating
Agreement. 

  

	 	(d)	For purposes of any Applicable Operating Agreement that contains a casing point election, approval of an AFE that includes the costs associated with completing a well shall be
deemed to be an election to participate in the completion of such well pursuant to the relevant provisions of such Applicable Operating Agreement. 

  

	 	(e)	When an operation is approved for greater amounts than those provided for in the applicable line items of the approved Annual Work Program and Budget, the Annual Work Program and
Budget shall be deemed to be revised accordingly. 

 Section 4.7 Contract Awards. Notwithstanding the
terms of any Applicable Operating Agreement to the contrary: 
  

	 	(a)	Subject to Sections 4.7(b), (c) and (d), Joint Development Operator and each Party Operator shall award each Development Operations Contract to the best qualified contractor
considering cost, ability, availability and HSSE performance considerations (in each case, in Joint Development Operator’s or Party Operator’s reasonable opinion), to perform the contract without the obligation to tender and without
informing or seeking the approval of the Operating Committee. The procedures set forth in this Section 4.7 shall not apply to any contracts that have been awarded, or in respect of which invitations to tender have been issued, on or before the
Closing Date, provided that the procedures set forth in this Section 4.7 shall apply to confirmations, service orders or purchase orders (whether written or oral) entered into on and after the Closing Date pursuant to existing master service
agreements that were effective prior to the Closing Date. 

  

 28 









	 	(b)	Prior to Joint Development Operator or any Party Operator entering into a Development Operations Contract with a Development Party or an Affiliate of a Development Party for which
one or more other Development Parties participating in such Development Operation that are not Affiliates of such Development Operations Contract counterparty will be responsible for all or a portion of the costs and expenses payable thereunder
(“Unaffiliated Participating Parties”), Joint Development Operator or such Party Operator shall obtain the affirmative vote of the Operating Committee members appointed by Unaffiliated Participating Parties holding collectively at
least seventy-five percent (75%) of the Participating Interests held by the Unaffiliated Participating Parties. 

 (c)

 (i) From and after January 1, 2010, prior to entering into a Development Operations Contract that can reasonably be
expected to result in aggregate payments to the counterparty of more than one million dollars (US$1,000,000) during any twelve (12) consecutive Calendar Month period, commencing as of January 1 in any Calendar Year, except as provided in
Section 4.7(c)(ii), Joint Development Operator and any Party Operator shall obtain proposals for such services from at least two (2) service providers. For the avoidance of doubt, a contract that automatically renews (is evergreen) on a
month-to-month or other periodic basis that would meet the $1,000,000 threshold if it remained in effect for an entire twelve (12) consecutive Calendar Month period commencing as of January 1 in any Calendar Year shall be considered
subject to the requirements of the preceding sentence. 
 (ii) If the Joint Development Operator or any Party Operator
desires to award a Development Operations Contract that would otherwise be subject to Section 4.7(c)(i) without tender of proposals from more than one service provider, whether because only one competent service provider can provide the
contracted-for-service or otherwise, the Joint Development Operator or such Party Operator may do so with the prior approval of the Operating Committee. Joint Development Operator and any Party Operator shall present a copy of the proposed
Development Operations Contract to the Operating Committee. Each Development Party shall notify the Joint Development Operator or such Party Operator, and the rest of the Operator Committee, of its approval or rejection of such Development
Operations Contract within fifteen (15) Business Days of its receipt of such Development Operations Contract. Failure of a Development Party to respond within such period shall be deemed an approval of the award of such Development Operations
Contract. Joint Development Operator and a Party Operator may only enter into a proposed Development Operations Contract that would otherwise be subject to Section 4.7(c)(i) without tender of proposals from more than one service provider if the
Operating Committee approves such Development Operations Contract. 
  

 29 








 (iii) To the extent that Joint Development Operator or any Party Operator enters into a
Development Operations Contract for which Joint Development Operator or any Party Operator is not required to obtain proposals from at least two (2) service providers pursuant to Section 4.7(c)(i) and such Development Operations Contract
can reasonably be expected to result in aggregate payment to the counterparty of more than one hundred thousand dollars (US$100,000), Joint Development Operator or such Party Operator shall keep a written record in its files that are subject to the
audit provisions of Section 2.2 of this Agreement and Exhibit “C” of the relevant Applicable Operating Agreement explaining why multiple bids were not obtained for such services 
 (iv) In connection with the foregoing, Joint Development Operator and each Party Operator shall keep a written record in its files that
are subject to the audit provisions of Section 2.2 of this Agreement and Exhibit “C” of each Joint Development Operating Agreement that (i) in the event that the Development Operations Contract is awarded pursuant to
Section 4.7(c)(i), includes the proposals obtained from the prospective service providers; or (ii) in the event that the Development Operations Contract is awarded pursuant to Section 4.7(c)(ii), includes the notice to the Operating
Committee and Operating Committee responses. 
  

	 	(d)	From and after the Closing Date, prior to entering into a Development Operations Contract not specifically and expressly approved as part of an approved Annual Work Program and
Budget that can reasonably be expected to result in aggregate payments to the counterparty of more than five million dollars (US$5,000,000) during any twelve (12) consecutive Calendar Month period, Joint Development Operator and any Party
Operator shall present a copy of the proposed Development Operations Contract to each Development Party, together with the tender list and tender evaluation criteria used to secure such proposed Development Operations Contract. Each Development
Party shall notify the Joint Development Operator or such Party Operator and the Operating Committee, of its approval or rejection of such Development Operations Contract within fifteen (15) Business Days of its receipt of such materials.
Failure of a Development Party to respond within such period shall be deemed an approval of such Development Operations Contract. Joint Development Operator and a Party Operator may only enter into such proposed Development Operations Contract to
the extent that the Operating Committee approves such Development Operations Contract. 

  

	 	(e)	Upon the reasonable written request of a Party, Joint Development Operator or a Party Operator shall provide such Party a copy of any written contract or contracts of a material
nature that are utilized in connection with Joint Development Operations or Sole Risk Development Operations in which such Party is participating, as well as other information that can reasonably be provided by such operator regarding the use and
performance of any such contract or contracts, except to the extent Joint Development Operator or such Party Operator may be prohibited from making any such disclosure under the terms and conditions of such contract and is unable through
commercially reasonable efforts to obtain consent for such disclosure. 

  

 30 









	 	(f)	With respect to written contracts that are reasonably expected to be effective for a period of one (1) or more Calendar Years and that are entered into from and after the
Closing Date, Joint Development Operator and each Party Operator shall include, in the case of Development Operations Contracts subject to Section 4.7(b), each of items (i) through (v) (inclusive) below, and shall use commercially
reasonable efforts to include, in the case of Development Operations Contracts subject to Section 4.7(c) or (d), each of items (i) through (iv) (inclusive) below: 

 (i) A right to assign such Development Operations Contract to a successor operator. 
 (ii) A right for the operator to enforce the Development Operations Contract on behalf of all beneficiaries and to recover the full
amount of damages suffered by all beneficiaries on their behalf. 
 (iii) A statement that the Participating Parties are
third party beneficiaries of the Development Operations Contract. 
 (iv) A right for any Participating Party to hold, review
and use any data and information, including seismic, geological, geophysical and other technical data and information that is the subject of such Development Operations Contract. 
 (v) A right for any Participating Party to enforce the contract as a third party beneficiary without a requirement to join the operator.

 Section 4.8 Area-Wide Operations. 
  

	 	(a)	Joint Development Operator shall conduct Area-Wide Operations on behalf of the Development Parties pursuant to the applicable approved Annual Work Program and Budget.


  

	 	(b)	All costs and liabilities incurred in Area-Wide Operations shall be borne and paid, and all assets acquired in such operations owned, by the Participating Parties in proportion to
their Participating Interests. 

  

	 	(c)	Each Development Party shall pay its share of estimated expenditures for Area-Wide Operations in which it participates, and such amounts shall be billed to or advanced by, as the
case may be, such Development Party in accordance with Section 2.2. 

  

 31 








 Section 4.9 Third Party Operators. For the avoidance of doubt, the Parties agree that
(a) the Development Work Program, Annual Work Program and Budget and other terms of Sections 4.1, 4.2, 4.3, 4.4, 4.5, 4.6, 4.8, 4.9 and 4.10 shall, though binding as between the Parties, not be binding upon any operator or non-operator that is
not a Party and (b) the terms of Section 4.7 shall not apply to any operations conducted by an operator that is not a Party. 
 Section 4.10 HSSE. 
  

	 	(a)	Within thirty (30) days following the Closing Date, the Development Parties shall use good faith efforts to develop HSSE principles to be observed in the conduct of Development
Operations (the “HSSE Principles”) which at a minimum include: (i) the goals of preventing injuries and providing a healthy, safe and secure working environment; (ii) protection of the environment; (iii) the
responsibility to seek continuous improvement in HSSE performance; and (iv) the principle that level of risk is the primary criterion for facilities design. 

  

	 	(b)	Within one hundred twenty (120) days following the Closing Date, the Development Parties shall use good faith efforts to develop an HSSE plan to be observed in the conduct of
Development Operations (the “HSSE Plan”) relating to the conduct of activities under this Agreement which is consistent with the HSSE Principles and the relevant technical standards and codes of practice issued by American
professional bodies, including the American Petroleum Institute, the American Society of Mechanical Engineers, the American National Standards Institute, and all applicable Laws. 

  

	 	(c)	Within two (2) years following the Closing Date, Joint Development Operator and each Party Operator shall have used good faith efforts to develop and implement an HSSE
management system to be observed in the conduct of Development Operations (an “HSSE Management System”) which addresses the HSSE risks specific to its duties under this Agreement, and any Applicable Operating Agreement, and the
management of controls to eliminate, reduce or mitigate HSSE risks. 

  

	 	(d)	From time to time, the Operating Committee may amend the HSSE Principles, HSSE Plan, and the HSSE Management System, as the case may be, subject to the voting thresholds and
procedures set forth herein. 

  

 32 








 ARTICLE 5 
 DEFAULT 
 Section 5.1 Default. 
  

	 	(a)	Any Development Party that fails to pay when due any amounts owed and undisputed under the terms of this Agreement or any Associated Agreement (including any amount included in an
approved Annual Work Program and Budget) and such failure is not cured within fifteen (15) days of such Development Party’s receipt of a Default Notice shall be in default under this Agreement, and shall be referred to herein as a
“Defaulting Party”. Joint Development Operator shall (or any Affected Party may) give notice of such default (a “Default Notice”) to the Defaulting Party and each of the other non-Defaulting Parties.


  

	 	(b)	For purposes of this Article 5, “Default Period” means the period beginning fifteen (15) days from the date of a Development Party’s receipt of a Default
Notice if such Development Party remains in default under Section 5.1(a), and ending when all of the Defaulting Party’s defaults have been remedied in full. 

  

	 	(c)	All amounts in default and not paid when due under this Agreement shall bear interest at the Default Interest Rate from the due date to the date of payment.


  

	 	(d)	For the avoidance of doubt (i) EXCO shall not be in default with respect to the payment of its Participating Interest share of Development Costs to the extent that BG is
responsible for such Development Costs as required by Section 2.1 and BG fails to pay its Carried Costs when due, and (ii) in the event BG fails to pay its Carried Costs when due and BG has not exercised its rights under
Section 5.1(e) with respect to such Carried Costs (if applicable), then BG shall be in default under this Agreement upon its receipt of a Default Notice and its failure to so cure such default as provided in Section 5.1(a). Except as set
forth in Section 5.1(e), no default by EXCO under this Agreement shall affect BG’s obligation to pay the Carried Costs when due as required by Section 2.1. 

  

	 	(e)	Notwithstanding anything to the contrary herein, at any time upon which EXCO is a Defaulting Party hereunder and prior to the Carry Termination Event, BG shall have the right but
not the obligation to set off its obligation to pay Carried Costs against the Total Amount in Default of EXCO upon notice to EXCO and, upon such set off, such obligation to pay such Carried Costs (to the extent of the amount so set off) shall be
deemed satisfied. 

 Section 5.2 Certain Consequences of Default. 
  

	 	(a)	Notwithstanding any other provision in this Agreement or any Associated Agreement to the contrary, during the Default Period, the Defaulting Party shall be subject to all rights and
remedies available to the Affected Parties under the relevant Applicable Operating Agreements, and in addition, shall have no right to: 

 (i) make or elect to participate in any proposal under this Agreement or any Applicable Operating Agreement; 
  

 33 








 (ii) vote on any matter with respect to which approval is required under the express terms of this
Agreement or any Associated Agreement (excluding any amendment or waiver of the terms of any such agreement); 
 (iii) call any Operating
Committee or subcommittee meeting; 
 (iv) vote on any matter coming before the Operating Committee or any subcommittee (except for any
amendment to the Development Work Program pursuant to Section 4.1); 
 (v) access any data or information relating to any operation
conducted under this Agreement or any Associated Agreement (except to the extent that the Defaulting Party is Joint Development Operator or is a Party Operator, in which case such Defaulting Party shall be entitled to such data and information as
may be necessary to perform its responsibilities in such capacity); 
 (vi) Transfer all or any part of its interests in its Joint
Development Interest or any other Subject Oil and Gas Asset, or Encumber all or any part of its interests in its Subject Oil and Gas Assets except in a case of (a) a Transfer of a Joint Development Interest to a Person or Encumbrance in favor
of a Person who simultaneously with such Transfer or Encumbrance satisfies in full the Total Amount in Default, or (b) a Credit Facility Encumbrance granted pursuant to a borrowing for which all or a portion of the proceeds thereof are used to
pay the entire amount of the Total Amount in Default; 
 (vii) withhold consent to any Transfer of all or an undivided portion of the Joint
Development Interest or a Material Interest of a non-defaulting Development Party pursuant to Article 7, or exercise its preferential purchase right provided for in Section 8.1 in the event of such a Transfer by a non-defaulting Development
Party or in Section 8.2 in the event of a Change in Control of a non-defaulting Development Party; or 
 (viii) elect to acquire any
portion of an Acquired Interest pursuant to Article 9. 
  

	 	(b)	In addition to the other remedies available to the Affected Parties under this Agreement and any other rights available to each Affected Party to recover its share of the Total
Amount in Default from and after the later to occur of the thirtieth (30th) day of the Default Period or the time upon which the Defaulting Party’s Escrow Account Balance is equal to zero (0), a Defaulting Party shall have no right to
receive its Entitlement from the Leases included in the Subject Oil and Gas Assets and the Affected Parties shall have the right to collect such Entitlement. 

  


 34 









	 	(c)	Furthermore, during the Default Period, the Defaulting Party shall be deemed to have approved, and shall join with the non-defaulting Development Party in taking, any actions
approved by the non-defaulting Development Parties during the Default Period which cannot be conducted as Sole Risk Development Operations under the terms of any Applicable Operating Agreement. 

  

	 	(d)	Any Default Notice shall include a statement of the amount of money that the Defaulting Party has failed to pay. 

  

	 	(e)	Upon the commencement of the Default Period, except with respect to any Carried Costs, Joint Development Operator, or if Joint Development Operator or any Affiliate of Joint
Development Operator is the Defaulting Party, any Affected Party or Affected Parties, shall send the non-defaulting Development Parties a statement of the sum of money that the Defaulting Party failed to pay, and the non-defaulting Development
Parties shall pay such amount within fifteen (15) days following receipt of the statement. If any non-defaulting Development Party fails to timely satisfy such obligations, such non-defaulting Development Party shall thereupon be a Defaulting
Party subject to the provisions of this Article 5. If all non-defaulting Development Parties fail to timely satisfy such obligations, the Development Parties shall be deemed to have unanimously determined not to make such expenditure and the
Defaulting Party shall no longer be deemed to be in default with respect to such expenditure. 

 Section 5.3 Right
to Costs of Enforcement. Each Affected Party shall be entitled to recover from the Defaulting Party all reasonable attorneys’ fees and other reasonable costs sustained in the collection of amounts owed by the Defaulting Party.

 Section 5.4 Cumulative and Additional Remedies. The rights and remedies granted to an Affected Party in this Article 5
shall be cumulative, not exclusive, and shall be in addition to any other rights and remedies that may be available to the Affected Party, at law, in equity or otherwise. Each right and remedy available to an Affected Party may be exercised from
time to time and so often and in such order as may be considered expedient by an Affected Party in its sole discretion. 
 Section 5.5 Reassignment Obligation. 
  

	 	(a)	 If BG becomes a Defaulting Party with respect to any Carried Costs, (a “Carried Cost Default”), then in addition to a Default Notice with respect
thereto, EXCO will give notice of such Carried Cost Default (a “Carried Cost Default Notice”) to BG. If BG fails to pay such owed and undisputed Carried Costs within fifteen (15) days of BG’s receipt of a Carried Cost
Default Notice, then EXCO (at the option of EXCO exercisable at any time prior to the cure of such Carried Cost Default, which option shall be exercised by notice to BG) may require BG to reassign to EXCO, effective as of the date of BG’s
failure to pay such Carried Costs when due, with special warranty of title against, and free and clear of, all claims by, through or under BG or its Affiliates, but not otherwise, an undivided 



  

 35 









	 	 
one-half ( 1/2
) of the Unpaid Carried Costs Percentage as of such time of all of BG’s and its Affiliates’ interests in the Deep Rights assigned by EXCO to BG pursuant to the Purchase Agreement and related
Subject Oil and Gas Assets, including wells (including all wells drilled on such Deep Rights in which BG and/or its Affiliates have participated). For the avoidance of doubt, no Deep Rights acquired by BG pursuant to Article 9 shall be subject to
the reassignment obligation. If EXCO elects to exercise its reassignment rights pursuant to this Section 5.5, BG shall be deemed to no longer be in default of its obligations to pay Carried Costs in accordance with the terms of Sections 2.1 and
2.2 of this Agreement, and such obligation to pay Carried Costs shall be deemed to be fully satisfied and this Agreement shall terminate. EXCO shall be entitled to exercise any and all rights and remedies that may be available to EXCO to enforce its
rights under this Section 5.5, whether set forth in this Agreement, the Applicable Operating Agreement, at Law, in equity (including specific performance of this Agreement) or otherwise. 


  

	 	(b)	Notwithstanding anything to the contrary in this Section 5.5, for the avoidance of doubt, unless and until EXCO exercises its rights to require BG to reassign a portion of the
Deep Rights under and in accordance with Section 5.5(a), BG shall have record title to the interests in the Deep Rights Transferred to BG pursuant to the Purchase Agreement and the conveyances executed in connection therewith and, except in the
event of the exercise by EXCO of its rights under Section 5.2(b) or in the event that EXCO exercises its right to require BG to reassign a portion of the Deep Rights under and in accordance with Section 5.5(a) effective as of the date of
BG’s failure to pay such Carried Costs when due, BG shall be entitled to all production from or attributable to such interests. 

 ARTICLE 6 
 TRANSFERS 
 Section 6.1 Maintenance of Uniform Interest; Minimum Participating Interest; Transfers by Defaulting Parties. 
  

	 	(a)	For the purpose of maintaining uniformity of ownership in the East Texas/North Louisiana Area as among the Development Parties, from and after the Closing Date, no Development Party
shall Transfer any portion of its Joint Development Interest unless such Transfer covers the entirety of such Development Party’s Joint Development Interest, or an undivided percentage of such Development Party’s Joint Development
Interest. Any Transfer of a Joint Development Interest shall also transfer a proportionate share of the Transferring Development Party’s interest in this Agreement and all of the Associated Agreements other than the Secondment Agreement. For
the avoidance of doubt, nothing in this Section 6.1(a) shall prevent a Development Party from Transferring a Material Interest or an Other Interest in accordance with the terms and conditions of this Agreement. 

  

 36 









	 	(b)	Except in the case of a Development Party transferring all of its Joint Development Interest, no Transfer of its Joint Development Interest shall be made by a Development Party
which results in the transferor or transferee holding a Participating Interest of less than ten percent (10%). 

  

	 	(c)	No Defaulting Party may Transfer all or any part of its Joint Development Interest or any other Subject Oil and Gas Asset unless and until the Total Amount in Default is paid by
such Defaulting Party or its transferee or any other Person on behalf of such Defaulting Party. 

 Section 6.2
Requirements for Transfer. 
  

	 	(a)	Any Transfer of all or any portion of a Joint Development Interest or any other interest of a Development Party in the Subject Oil and Gas Assets or Encumbrance of all or any
portion of a Subject Oil and Gas Asset must expressly be made subject to this Agreement and the Associated Agreements. No Credit Facility Encumbrance shall be subject to the terms and conditions of this Agreement or any Associated Agreement, except
that Credit Facility Encumbrances granted at or after the Closing Date (other than Credit Facility Encumbrances granted pursuant to the Existing EXCO Credit Facility) shall be subject to Section 3.5 (excluding Section 3.5(e)) and Article 8
of this Agreement and all Joint Development Operating Agreements. 

  

	 	(b)	A transferee of any Transfer of a Joint Development Interest shall have no rights in this Agreement or the Associated Agreements unless and until it provides the non-transferring
Development Parties, and Joint Development Operator executed counterparts of the instrument or instruments providing for such Transfer; by execution and delivery of an instrument in substantially the form attached hereto as Exhibit “F”
(the “Assumption Agreement”) expressly undertakes to be bound by the terms of this Agreement and the Associated Agreements. 

 Section 6.3 Liability of Transferor/Transferee. With respect to any Transfer of a Joint Development Interest, a transferring Development Party shall, notwithstanding such Transfer, be liable to the
other Development Parties and Joint Development Operator for its obligation to fund its Participating Interest share (as of the time of the Transfer) of the Development Operations included in approved Annual Work Program and Budgets (including
multi-year expenditures included in more than one Annual Work Program and Budget) and Sole Risk Development Operations in which such Development Party is participating, and for all other obligations, in each case, accrued under this Agreement or any
Associated Agreement on or prior to such Transfer, but shall be released from any other obligations thereafter accruing under this Agreement or such Associated Agreement with respect to the Joint Development Interest being Transferred, except in the
case where the Transfer at issue is made to an Affiliate or where the lender(s) with respect to a Credit Facility Foreclosure foreclose(s) on all or any part of a Development Party’s Joint Development Interest, in which cases the transferring
Development Party or Development Party subject to the foreclosure, as applicable, shall remain 
  

 37 








 
primarily liable for all such obligations. For purposes of this Section 6.3, costs of plugging and abandoning wells and decommissioning facilities in
which the transferring Development Party has participated (or has paid a share of the costs under the preceding sentence) shall be considered to accrue at the time when applicable operator cash calls such amounts or the Development Parties are
required to provide security for such amounts under the terms of this Agreement or the Associated Agreements, whichever is earlier. 
 Section 6.4 Encumbrances by Parties. 
  

	 	(a)	Nothing contained in this Article 6 or in Articles 7 or 8 shall prevent a Development Party from Encumbering all or any undivided share of its Joint Development Interest or any
other interest in the Subject Oil and Gas Interests to a third party after the Closing Date, provided that: 

 (i) such
Development Party shall remain liable for all obligations relating to such Joint Development Interest except as provided in Section 6.3; and 
 (ii) other than with respect to a Credit Facility Encumbrance, such Encumbrance shall be expressly subordinated to the rights of the other Parties under this Agreement, including any mortgage or security interest provided for herein or in
the Associated Agreements, which subordination shall be expressly for the benefit of the other Parties. 
  

	 	(b)	The liens and security interests created for the benefit of the Development Parties under this Agreement and any Applicable Operating Agreement (other than the Development
Parties’ security interest in the Escrow Deposit Account) are and will be, in all respects, subordinate to the liens and security interests created pursuant to a Credit Facility Encumbrance regardless of the time of execution of the instruments
creating such liens and/or security interests and/or the filing of such liens and security interests in the applicable county or parish or other governmental office. Each Development Party agrees to execute any instruments requested by any Credit
Facility Encumbrance lender reasonably necessary to reflect the subordination of any liens or security interests created for the benefit of the Development Parties under this Agreement or any Associated Agreement (other than the Development
Parties’ security interests in the Escrow Deposit Account) to the liens and security interests created pursuant to such Credit Facility Encumbrance. 

 ARTICLE 7 
 CONSENT TO ASSIGNMENT 
 Section 7.1 Certain Transfers during Initial Three Year Period. From and after the Closing Date and until the third anniversary of the
Closing Date (such period, the “Initial Three Year Period”), no Development Party shall be permitted to Transfer all or any part of its Joint Development Interest or other Material Interest or undergo a Change in Control without the
prior written consent of each other Development Party, which consent may be withheld for any reason in the sole discretion of such other Development Party, provided that no such consent 
  

 38 








 
shall be required for any Transfer of all or any part of a Development Party’s Joint Development Interest or other Material Interest to an Affiliate of
such Development Party, provided that any subsequent Transfer of a Material Interest by such Affiliate of such Development Party to a Person that is not an Affiliate of such Development Party during the Initial Three Year Period shall require the
prior written consent of the other Development Parties, which consent may be withheld for any reason in the sole discretion of such other Development Parties. Further, during the Initial Three Year Period, no Affiliate of a Development Party that
has been Transferred a Material Interest may undergo a Change in Control without the prior written consent of each other Development Party, which consent may be withheld for any reason in the sole discretion of such other Development Party.

 Section 7.2 Other Transfers. A Development Party shall be permitted to Transfer all or any part of its Joint
Development Interest after the Initial Three Year Period, provided that a transferee must have the financial ability to perform its future payment obligations hereunder and under the Associated Agreements and the technical ability to participate in
the planning of future operations. 
 Section 7.3 Additional Consent Requirements. For the avoidance of doubt, any
Transfer of a Joint Development Interest or a Material Interest shall also be subject to any restrictions on Transfer set forth in the Associated Agreements in addition to those set forth in this Agreement, provided that to the extent any such
Associated Agreement contains a right to withhold consent to Transfer or a preferential purchase right in favor of another Development Party, as between the transferring Development Party and the other Development Parties that are parties to such
Associated Agreement, any such consent right or preferential purchase right in such Associated Agreement shall not apply. 
 Section 7.4 Consents for Transfer of Joint Development or Party Operatorship. Neither Joint Development Operator nor any Party Operator may transfer all or any part of its rights or obligations as Joint Development
Operator hereunder or as Party Operator under any Applicable Operating Agreement without the prior written consent of each Development Party, which consent may be withheld for any reason in the sole discretion of such Development Party. 

ARTICLE 8 
 PREFERENTIAL RIGHT TO
PURCHASE; CHANGES IN CONTROL 
 Section 8.1 Preferential Right to Purchase. Any Transfer of all or a portion of a
Development Party’s Joint Development Interest or a Material Interest, other than a Transfer thereof to a Wholly-Owned Affiliate shall be subject to the following procedure. 
  

	 	(a)	 Once the final terms and conditions of such Transfer have been fully negotiated and are binding upon the parties thereto, the transferring Development Party shall
disclose all such final terms and conditions as are relevant to the acquisition of the Joint Development Interest or Material Interest, as applicable (and, if applicable, the determination of the Cash Value of the Joint Development Interest or
Material Interest, as applicable) in a notice to the non-transferring Development Parties, which notice shall be accompanied by a copy of all instruments or relevant 



  

 39 









	 	 
portions of instruments establishing such terms and conditions. Each non-transferring Development Party shall have the right to acquire the Joint Development
Interest or any Material Interest, as applicable, subject to such proposed Transfer from the transferring Development Party on the terms and conditions described in Sections 8.1(c) and 8.1(d), as applicable, if, within sixty (60) days of the
transferring Development Party’s notice, the non-transferring Development Party delivers to the transferring Development Party a counter-notification that it accepts such terms and conditions without reservations or conditions (subject to the
other provisions of this Section 8.1, where applicable). If no non-transferring Development Party delivers such counter-notification within such time, such Transfer to the proposed transferee may proceed without further notice, subject to the
other provisions of this Agreement, under terms and conditions no more favorable to the transferee than those set forth in the notice to the non-transferring Development Parties, provided that such Transfer shall be concluded within one hundred
twenty (120) days from the date of the notice. If such Transfer fails to be concluded within such period and the parties thereto desire thereafter to proceed with such proposed Transfer, the transferring Development Party shall be required to
re-offer the Joint Development Interest or Material Interest, as applicable, subject to the Transfer to the non-transferring Development Parties in accordance with the terms and conditions of this Section 8.1. No Development Party shall have a
right under this Section 8.1 to acquire any asset other than a Joint Development Interest or Material Interest, as applicable, nor shall a Development Party be required to acquire any asset other than a Joint Development Interest or Material
Interest, as applicable, regardless of whether other properties are included in the Transfer at issue. 


  

	 	(b)	If more than one non-transferring Development Party counter-notifies that it intends to acquire the transferring Development Party’s Joint Development Interest or Material
Interest, as applicable, that is subject to the proposed Transfer, then each such Development Party shall acquire a proportion of the Joint Development Interest or Material Interest, as applicable, to be transferred equal to the ratio of its own
Participating Interest to the total Participating Interests of all counter-notifying Development Parties, unless the counter-notifying Development Parties otherwise agree. 

  

	 	(c)	In the event of a Cash Transfer that does not involve other properties as part of a wider transaction, each non-transferring Development Party shall have a right to acquire the
Joint Development Interest or Material Interest, as applicable, subject to the proposed Transfer on the same final terms and conditions as were negotiated with the proposed transferee. 

  

	 	(d)	 In the event of a Transfer of all or a portion of a Joint Development Interest or Material Interest, as applicable, that is not a Cash Transfer or involves other
properties included in a wider transaction (package deal), the transferring 



  

 40 









	 	 
Development Party shall include in its notification to the non-transferring Development Parties a statement of the proposed Cash Value of the Joint
Development Interest or Material Interest, as applicable, subject to the proposed Transfer, and each non-transferring Development Party shall have a right to acquire such Joint Development Interest or Material Interest, as applicable, on the same
final terms and conditions as were negotiated with the proposed transferee except that it shall pay the Cash Value in immediately available funds at the closing of the Transfer in lieu of the consideration payable in the third party offer, and the
terms and conditions of the applicable instruments shall be modified as necessary to reflect the acquisition of a Joint Development Interest or Material Interest, as applicable, for cash. In the case of a package sale, the non-transferring
Development Parties may not acquire the Joint Development Interest or Material Interest, as applicable, subject to the proposed package sale unless and until the completion of the wider transaction (as modified by the exclusion of properties subject
to preemptive rights or excluded for other reasons) with the package sale transferee. If for any reason the package sale terminates without completion, the non-transferring Development Parties’ rights to acquire the Joint Development Interest
or Material Interest, as applicable, subject to the proposed package sale shall also terminate. 


  

	 	(e)	For purposes of Section 8.1(d), the Cash Value proposed by the transferring Development Party in its notice shall be conclusively deemed correct unless any non-transferring
Development Party gives notice to the transferring Development Party within thirty (30) days of receipt of the transferring Development Party’s notice stating that it does not agree with the statement of the Cash Value, stating the Cash
Value it believes is correct, and providing any supporting information that it believes is helpful. In such event, the Development Parties shall have fifteen (15) days in which to attempt to negotiate an agreement on the applicable Cash Value.
If no agreement has been reached by the end of such fifteen (15) day period, any affected Development Party shall be entitled to refer the matter to an independent expert as provided in Section 13.3 for determination of the Cash Value,
provided that the transferring Development Party may elect to terminate the proposed Transfer, and any non-transferring Development Party may elect to revoke its notice of intention to purchase, in either case by notice to the other Development
Parties at any time prior to the time that the independent expert is retained pursuant to such provision. The Cash Value to be submitted to the independent expert by the transferring Development Party shall be the Cash Value provided by such
Development Party in the notice provided to the non-transferring Development Parties pursuant to Section 8.1(d), and the Cash Value to be submitted to the independent expert by each non-transferring Development Party shall be the Cash Value
provided by such Development Party in the notice provided to the transferring Development Party pursuant to this Section 8.1(e). 

  

 41 








 Section 8.2 Changes in Control. 
  

	 	(a)	Any Change in Control of a Development Party shall be subject to the terms and conditions of this Section 8.2. For purposes of this Section 8.2, the term “Acquired
Development Party” shall refer to the Development Party that is subject to a Change in Control, “Other Development Parties” shall refer to all other Development Parties not subject to the Change in Control, and
“Acquiror” shall refer to the third party proposing to acquire Control of the Acquired Development Party in the Change in Control. 

  

	 	(b)	Once the final terms and conditions of a Change in Control have been fully negotiated and are binding upon the parties thereto, the Acquired Development Party shall disclose all
such final terms and conditions as are relevant to the acquisition of such Acquired Development Party’s Joint Development Interest and other interests in the Subject Oil and Gas Assets and the determination of the Cash Value of that Joint
Development Interest and other interests in a notice to the Other Development Parties, which notice shall be accompanied by a copy of all instruments or relevant portions of instruments establishing such terms and conditions. Each Other Development
Party shall have the right to acquire the Acquired Development Party’s Joint Development Interest and other interests in the Subject Oil and Gas Assets on the terms and conditions described in Section 8.2(d) if, within sixty (60) days
of the Acquired Development Party’s notice, the Other Development Party delivers to the Acquired Development Party a counter-notification that it accepts such terms and conditions without reservations or conditions (subject to the other
provisions of this Section 8.2, where applicable). If no Other Development Party delivers such counter-notification, the Change in Control may proceed without further notice, subject to the other provisions of this Article 8, under terms and
conditions no more favorable to the Acquiror than those set forth in the notice to the Other Development Parties, provided that the Change in Control shall be concluded within one hundred twenty (120) days from the date of the notice. If the
Change in Control fails to be concluded within such period and the direct or indirect owners, as the case may be, of the Acquired Development Party desire thereafter to proceed with such proposed Change in Control, the Acquired Development Party
shall be required to re-offer the Joint Development Interest and other interests in the Subject Oil and Gas Assets subject to the Change in Control to the Other Development Parties in accordance with the terms and conditions of this
Section 8.2. No Other Development Party shall have a right under this Section 8.2 to acquire any asset other than a Joint Development Interest, nor shall any Other Development Party be required to acquire any asset other than a Joint
Development Interest and other interests in the Subject Oil and Gas Assets, regardless of whether other properties are subject to the Change in Control. 

  

 42 









	 	(c)	If more than one Other Development Party counter-notifies that it intends to acquire the Acquired Development Party’s Joint Development Interest and other interests in the
Subject Oil and Gas Assets that is subject to the proposed Change in Control, then each such Other Development Party shall acquire a proportion of the Joint Development Interest subject to the Change in Control equal to the ratio of its own
Participating Interest to the total Participating Interests of all counter-notifying Other Development Parties, unless the counter-notifying Other Development Parties otherwise agree. 

  

	 	(d)	The Acquired Development Party shall include in its notification to the Other Development Parties a statement of the proposed Cash Value of the Joint Development Interest subject to
the proposed Change in Control, and each Other Development Party shall have a right to acquire such Joint Development Interest and other interests in the Subject Oil and Gas Assets for the Cash Value, on the final terms and conditions negotiated
with the Acquiror that are relevant to the acquisition of a Joint Development Interest and other interests in the Subject Oil and Gas Assets for cash. No Other Development Party may acquire the Acquired Development Party’s Joint Development
Interest and other interests in the Subject Oil and Gas Assets pursuant to this Section 8.2 unless and until completion of the Change in Control. If for any reason the Change in Control agreement terminates without completion, the Other
Development Parties’ rights to acquire the Joint Development Interest and other interests in the Subject Oil and Gas Assets subject to the proposed Change in Control shall also terminate. 

  

	 	(e)	For purposes of Section 8.2(d), the Cash Value proposed by the Acquired Development Party in its notice shall be conclusively deemed correct unless any Other Development Party
gives notice to the Acquired Development Party within thirty (30) days of receipt of the Acquired Development Party’s notice stating that it does not agree with the Acquired Development Party’s statement of the Cash Value, stating the
Cash Value it believes is correct, and providing any supporting information that it believes is helpful. In such event, the Development Parties shall have fifteen (15) days in which to attempt to negotiate an agreement on the applicable Cash
Value. If no agreement has been reached by the end of such fifteen (15) day period, any affected Development Party shall be entitled to refer the matter to an independent expert as provided in Section 13.3 for determination of the Cash
Value, provided that the Acquired Development Party may elect to terminate the proposed Change in Control, and any Other Development Party may elect to revoke its notice of intention to purchase, in either case by notice to the other Development
Parties at any time prior to the time that the independent expert is retained pursuant to such provision. The Cash Value to be submitted to the independent expert by the Acquired Development Party shall be the Cash Value provided by such Acquired
Development Party in the notice provided to the non-transferring Development Parties pursuant to Section 8.2(d), and the Cash Value to be submitted to the independent expert by each Other Development Party shall be the Cash Value provided by
such Other Development Party in the notice provided to the acquired Development Party pursuant to this Section 8.2(e). 

  

 43 









	 	(f)	Within thirty (30) days of receiving notice of a proposed Change in Control of EXCO, BG shall have the right but not the obligation to require EOC to resign as Joint
Development Operator and to require EXCO Operator to resign as operator under each Applicable Operating Agreement in which it serves in such capacity, in each case, simultaneous with the consummation of such Change in Control. Such right shall be
exercisable by BG by notice to EXCO. Upon any such election by BG, simultaneous with the consummation of the Change in Control, BG or BG’s designee shall automatically be deemed to be Joint Development Operator and the successor operator under
each Joint Development Operating Agreement, and EXCO or its successor in interest shall vote for BG or BG’s designee to serve as the successor operator under each Applicable Operating Agreement where a successor operator is to be elected as a
result of EXCO Operator’s resignation. If for any reason the Change in Control agreement terminates without completion, BG’s right to require EOC and EXCO Operator to resign as Joint Development Operator and operator, respectively, subject
to the proposed Change in Control shall also terminate. 

 ARTICLE 9 
 AREA OF MUTUAL INTEREST; CERTAIN RENTALS 
 Section 9.1 Creation of Area of Mutual Interest. The Development Parties agree that the East Texas/North Louisiana Area shall be an area of mutual interest. 
 Section 9.2 Area of Mutual Interest Procedures. 
  

	 	(a)	 If, during the period commencing on June 29, 2009 and ending on the five (5) year anniversary of the Closing Date, a Development Party or any Affiliate
thereof (such Development Party, whether it or its Affiliate is the acquiror, an “Acquiring Development Party”) directly or indirectly acquires any interest from a non-Affiliate (a “Selling Party”) in any Oil and
Gas Asset (such Oil and Gas Asset, the “Acquired Interest”), whether by lease, sublease, purchase, farmout, acquisition of shares or other equity interests in an entity directly or indirectly owning the Acquired Interest or
otherwise, the Acquiring Development Party shall provide written notice (an “Offer Notice”) to the other Development Parties (each, a “Non-Acquiring Development Party”), provided that no Acquiring Development Party
shall be required to deliver any Offer Notices relating to the acquisition by such Acquiring Development Party or any of its Affiliates of any Acquired Interests acquired on or after June 29, 2009 but prior to the Closing Date until five
(5) Business Days after the Closing Date. Subject to the rights of any third parties under any relevant Applicable Operating Agreement, each Non-Acquiring Development Party shall have the right (but not the obligation) to acquire its undivided
Participating Interest share in the Acquired Interest (the 



  

 44 









	 	 
“Offered Interest”) upon the same terms and conditions on which the Acquiring Development Party or its Affiliate acquired the Acquired
Interest, subject to assuming its Participating Interest share of all duties and obligations with respect to the Acquired Interest and paying the Acquiring Development Party the Non-Acquiring Development Party’s Participating Interest share of
any consideration paid by the Acquiring Development Party or its Affiliate (and, in the case of Acquired Interests including Leases, any lease broker costs incurred in acquiring such Leases). Notwithstanding anything to the contrary in the preceding
sentence, in the event that one or more Non-Acquiring Development Parties elect not to acquire their Offered Interests, each Non-Acquiring Development Party’s Offered Interest shall be that portion of the Acquired Interest that such
Non-Acquired Development Party’s Participating Interest bears to the aggregate Participating Interests of the Acquiring Development Party and the Non-Acquiring Parties electing to participate in the acquisition of the Acquired Interest. An
Acquiring Development Party shall use commercially reasonable efforts to assign a share of its or its Affiliate’s rights and obligations under the acquisition documents to the Non-Acquiring Development Parties, provided that the Acquiring
Development Party shall not be required pay cash or otherwise surrender value or incur any liability to the Selling Party to obtain such a right. 


  

	 	(b)	Each Non-Acquiring Development Party shall have a period of sixty (60) days after receipt of the Offer Notice to notify the Acquiring Development Party in writing whether it
elects to acquire its Offered Interest. Failure to give timely notice of such election shall be deemed an election not to acquire its Offered Interest. If a Non-Acquiring Development Party timely elects to acquire its Offered Interest, then the
Acquiring Development Party and such Non-Acquiring Development Party shall enter into agreements for the Transfer of the Non-Acquiring Development Party’s Participating Interest share of such rights and obligations on substantially the same
terms as provided in the agreements between the Selling Party and the Acquiring Development Party or its Affiliate (with such changes as may be necessitated by the differences in parties, the transfer of only a Participating Interest share, the
inclusion of lease broker costs to the extent required by Section 9.2(a), and, if applicable, the apportionment of rights from a package deal or the payment of Cash Value in lieu of other consideration), provided that the Acquiring Development
Party shall in no event have liability to the Non-Acquiring Development Party for representations, warranties or indemnities with respect to the Acquired Interest in excess of the Non-Acquiring Party’s Participating Interest share of amounts
that the Acquiring Development Party or its Affiliate actually recovers under the third party acquisition agreement and related documents for the same matters. The Parties shall execute and deliver the applicable documents and take such other
actions as shall be reasonably required to accomplish the transfer promptly after the Non-Acquiring Development Party’s exercise of its option. 

  

 45 









	 	(c)	If the Acquired Interest arises out of a farmout agreement or similar agreement requiring the drilling of a well or the performance of other similar obligations, the election by a
Non-Acquiring Development Party to acquire its Offered Interest shall also constitute an election by such Non-Acquiring Development Party to join the Acquiring Development Party in all operations and obligations required to earn such Offered
Interest under such an agreement and to bear its proportion of the cost thereof (including, if applicable, any Carried Costs relating thereto and such operations shall automatically be added to the Development Work Program and the relevant Annual
Work Program and Budget). However, nothing in this Section 9.2(c) shall be construed to prevent any Development Party from electing not to join in a completion attempt of an earning or obligation well drilled under the terms of a farmout
agreement or similar agreement if such Development Party is not obligated to do so under the terms of such farmout agreement or similar agreement. 

  

	 	(d)	In the event an Acquired Interest is not acquired pursuant to a Cash Transfer or is acquired with other properties included in a wider transaction (package deal), the Acquiring
Development Party shall include in its notification to the Non-Acquiring Development Parties a statement of the Cash Value of the Acquired Interest (excluding the drilling of wells or performance of other obligations included as part of the
consideration), and each Non-Acquiring Development Party shall have a right to acquire its Offered Interest on the same final terms and conditions as were negotiated with the proposed transferor except that it shall pay the Cash Value in immediately
available funds to the Acquiring Development Party at the time of its acquisition of the Offered Interest in lieu of the consideration (excluding the drilling of wells or performance of other obligations included as part of the consideration)
payable in the third party offer, and the terms and conditions of the applicable instruments shall be modified to reflect the acquisition of the Offered Interest for cash. In the case of a package sale, the Non-Acquiring Development Parties may not
acquire an interest in the Acquired Interest subject to the proposed package sale unless and until the completion of the wider transaction (as modified by the exclusion of properties subject to preemptive rights or excluded for other reasons) with
the package sale transferor. If for any reason the package sale terminates without completion, the Non-Acquiring Development Parties’ rights to acquire the Acquired Interest subject to the proposed package sale shall also terminate.


  

	 	(e)	 For purposes of Section 9.2(d), the Cash Value proposed by the Acquiring Development Party in its notice shall be conclusively deemed correct unless any
Non-Acquiring Development Party gives notice to the Acquiring Development Party within thirty (30) days of its receipt of the Offer Notice stating that it does not agree with the Acquiring Development Party’s statement of the Cash Value,
stating the Cash Value (excluding the drilling of wells or performance of other obligations included as part of the consideration) it believes is correct, and providing any supporting information that it believes is helpful. In such event, the




  

 46 









	 	 
Development Parties shall have fifteen (15) days in which to attempt to negotiate an agreement on the applicable Cash Value. If no agreement has been
reached by the end of such fifteen (15) day period, any affected Development Party shall be entitled to refer the matter to an independent expert as provided in Section 13.3 for determination of the Cash Value, provided that the Acquiring
Development Party may elect to terminate the proposed acquisition of the Acquired Interest, and any Non-Acquiring Development Party may elect to revoke its notice of intention to purchase, in either case by notice to the other Development Parties at
any time prior to the time that the independent expert is retained pursuant to such provision. The Cash Value to be submitted to the independent expert by the Acquiring Development Party shall be the Cash Value provided by such Acquiring Development
Party in the notice provided to the Non-Acquiring Development Parties pursuant to Section 9.1(d), and the Cash Value to be submitted to the independent expert by each Non-Acquiring Development Party shall be the Cash Value provided by such
Non-Acquiring Development Party in the notice provided to the Acquiring Development Party pursuant to this Section 9.1(e). 


  

	 	(f)	If a Non-Acquiring Development Party elects not to acquire or fails to make a timely election to acquire the Offered Interest, such Non-Acquiring Development Party shall have no
further rights whatsoever with regard to the Acquired Interest and such Acquired Interest shall be excluded for all purposes from this Agreement and the Associated Agreements and the provisions thereof, except that, in the case that EXCO is a
Non-Acquiring Development Party that elects not to acquire or fails to make a timely election to acquire the Offered Interest, BG shall nonetheless have the right but not the obligation to require EXCO to operate such Acquired Interest on its behalf
pursuant to a Joint Development Operating Agreement. 

  

	 	(g)	Notwithstanding anything to the contrary herein, this Article 9 shall not be applicable to: (i) Transfers among a Development Party and its Affiliates; (ii) acquisitions
of interests in any entity or entities directly or indirectly owning an Acquired Asset if the direct or indirect interest in the Acquired Assets makes up less than twenty-five percent (25%) of the total Cash Value of the interest acquired or to
be acquired, or (iii) any Excluded Assets. 

  

	 	(h)	For the avoidance of doubt, the Additional Interests shall be Acquired Interests for purposes of this Agreement in accordance with the Purchase Agreement, and EXCO shall offer the
Additional Interests to BG on the Closing Date in accordance with the terms of this Section 9.2. 

  

	 	(i)	The Development Parties shall use commercially reasonable efforts to cause a Development Party, and not a third party, to serve as operator of any Acquired Interest.


  

 47 









	 	(j)	Each Development Party agrees to cause its Affiliates to comply with this Article 9. 

 Section 9.3 Payment of Certain Rentals. If, at any time within the period that is thirty (30) days prior to the expiration of any Lease included in the Subject Assets, no approved Annual Work
Program and Budget contemplates commencement of drilling operations or payment of delay rentals as may be necessary to maintain such Lease in existence, a Development Party with an interest in such Lease shall have the right to pay such delay rental
in order to maintain such Lease in existence (any Development Party paying such delay rental, a “Maintaining Development Party”), and within ten (10) days of the payment of any such delay rental, shall provide notice of such
payment (a “Delay Rental Notice”) to the other Parties. Each other Development Party with an interest in such Lease shall have the right (but not the obligation) to reimburse the Maintaining Development Party that portion of such
delay rental that its Participating Interest bears to the aggregate Participating Interests of those Development Parties with interests in such Lease (or, if there are Releasing Development Parties, that portion of such delay rental that its
Participating Interest bears to the aggregate Participating Interests of the Non-Releasing Development Parties) by notice to the other Parties and reimbursement of the Maintaining Development Party within ten (10) days of its receipt of the
Delay Rental Notice. Failure of a Development Party to so reimburse the Maintaining Development Party (any such Development Party, a “Releasing Development Party”) shall result in such Releasing Development Party being deemed to
have Transferred its interest in the applicable Lease to Maintaining Development Party and the Development Parties paying a portion of such delay rental (all such Development Parties, the “Non-Releasing Development Parties”) in the
proportions that such Non-Releasing Development Parties’ Participating Interests in such Lease bear to the aggregate Participating Interests in such Lease of such Non-Releasing Development Parties, effective as of the first day of the Calendar
Month in which such delay rental is paid. A Releasing Development Party shall, without delay following any request from any Non-Releasing Development Party, do any act required to be done by applicable Law or any applicable contract in order to
render the Transfer of an affected Lease legally valid, including obtaining all necessary consents and approvals, and shall execute any document and take such other actions as may be necessary in order to effect a prompt and valid transfer. The
Releasing Development Party shall be obligated to promptly remove any Encumbrances which may exist on the affected Lease. In the event required consents and approvals are not timely obtained, the Releasing Development Party shall hold the
Transferred Lease in trust for the Non-Releasing Development Parties. 
 ARTICLE 10 
 TAXES 
 Section 10.1 Tax
Partnership. The Development Parties intend and expect that the transactions contemplated by the Purchase Agreement, this Agreement and the Associated Agreements, 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 creation of a partnership (the “Tax Partnership”) in which BG and EXCO are treated as partners,
with the Tax Partnership being treated for tax purposes as holding the Subject Oil and Gas Assets and engaging in all activities of the Development Parties with respect to the Subject Oil and Gas Assets, (b) a contribution by EXCO of all of the
Subject 
  

 48 








 
Oil and Gas Assets to the Tax Partnership; (c) a contribution of the Adjusted Closing Cash Consideration (as defined in the Purchase Agreement) and a
commitment to fund the Carried Costs allocable to it under this Agreement to the Tax Partnership by BG in exchange for a fifty percent (50%) interest therein, (d) a distribution to EXCO of the Adjusted Closing Cash Consideration
(i) as a reimbursement of EXCO’s preformation expenditures with respect to the Subject Oil and Gas Assets within the meaning of Treasury Regulations Section 1.707-4(d) to the extent applicable and (ii) in a transaction subject to
treatment under Section 707(a) of the Internal Revenue Code of 1986, as amended, and its implementing Treasury Regulations as in part a sale, and in part a contribution, of the Subject Oil and Gas Assets to the Tax Partnership to the extent
that Treasure Regulations Section 1.707-4(d) is inapplicable, and (e) the realization by the Tax Partnership of all items of income or gain and the incurrence by the Tax Partnership of all items of costs or expenses attributable to the
ownership, operation or disposition of the Subject Oil and Gas Assets, notwithstanding that such items are realized, paid or incurred by the Parties individually. The governing terms and conditions of the Tax Partnership are set forth in Exhibit
“G” hereto. 
 Section 10.2 Tax Information. Joint Development Operator and each Party Operator shall
provide each Development Party, in a timely manner and at each Development Party’s sole expense, with information with respect to Development Operations as such Development Party may reasonably request for preparation of its tax returns or

Section 9.3. 
 ARTICLE 13 
 GOVERNING LAW; DISPUTE RESOLUTION; EXPERT PROCEEDINGS 
 Section 13.1 Governing Law. 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. 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 LAW, ANY RIGHT IT MAY HAVE TO A
TRIAL BY JURY IN RESPECT OF ANY DISPUTE. 
 Section 13.2 Dispute Resolution. 
  

	 	(a)	Except for matters that are expressly made subject to the dispute resolution procedures set forth in Section 13.3, 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 American Arbitration Association (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 any Party providing notice to the other Parties of a Dispute,
if there are two Parties or two groups of Parties to a Dispute, each Party or group of Parties to such Dispute 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 



  

 50 









	 	 
Party or group of Parties fails to appoint an 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. In the event that there are more than two Parties or groups of Parties to an arbitration, the Parties to the arbitration shall endeavor to agree on the appointment of the three arbitrators
within thirty (30) days of the written request for arbitration. In the event the Parties cannot reach agreement on the selection of three arbitrators within the time permitted, all arbitrators not yet appointed shall be appointed by the AAA in
accordance with the AAA Rules. Any arbitrator appointed by the Party-appointed arbitrators or the AAA shall be a member of the Large, Complex Commercial Case Panel of the AAA or a member of the Center of Public Resources Panel of Distinguished
Neutrals. All arbitrators shall be and remain at all times independent and impartial, and, once appointed, no arbitrator shall have any ex parte communications with any of the Parties concerning the arbitration or the underlying Dispute other than
communications directly concerning the selection of the presiding arbitrator, when applicable. All arbitrators shall be qualified by education, training, or experience to resolve the Dispute. No arbitrator shall have been an employee or consultant
to any Party or any of its Affiliates within the five (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 13.2, 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 the Default Interest Rate, from the date of any default, breach, or other 



  

 51 









	 	 
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. 

  

	 	(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 14.2. 

 Section 13.3 Expert Proceedings. For any decision referred to an
expert under this Agreement, the Parties hereby agree that such decision shall be conducted expeditiously by an expert selected unanimously by the Development Parties. The expert is not an arbitrator of the dispute and shall not be deemed to be
acting in an arbitral capacity. The expert shall not (without the written consent of the Development Parties) be appointed to act as an arbitrator or as adviser to any Development Party arbitrated pursuant to Section 13.2, provided that nothing
in this sentence shall preclude any Development Party from using the expert as a witness regarding the proper conduct of the expert procedure. The Development Party desiring an expert determination shall give the other Development Party written
notice of the request for such determination. If the Development Parties are unable to agree upon an expert within ten (10) days after receipt of the notice of request for an expert determination, then, upon the request of any of the
Development Parties, the AAA shall appoint such expert. The expert, once appointed, shall have no ex parte communications with the Development Parties concerning the expert determination or the underlying dispute. All communications between any
Development Party and the expert shall be conducted in writing, with copies sent simultaneously to the other Development Party in the same manner, or at a meeting to which all Development Parties have been invited and of which such Development
Parties have been provided at least five (5) Business Days notice. Within thirty (30) days after the expert’s acceptance of its appointment, the Development Parties shall provide the expert with a report containing their proposal for
the resolution of the matter and the reasons therefor, accompanied by all relevant supporting information and data. Within sixty (60) days of receipt of the above-described materials and after receipt of additional information or data as may be
required by the expert, the expert shall select the proposal which it finds more consistent with the terms of this Agreement. The expert 
  

 52 








 
may not propose alternate positions or award damages, interest or penalties to any Party with respect to any matter. The expert’s decision shall be
final and binding on the Development Parties. Any Party that fails or refuses to honor the decision of an expert shall be in default under this Agreement.
