 Section 3.4 Restricted Securities. ESAS understands that the Securities have not

concerning EXCO and to obtain additional information that it has requested to verify the information contained in this Section 3.6. With the assistance of ESAS’s own professional advisors, to the extent that ESAS has deemed
appropriate, ESAS has made its own legal, tax, accounting and financial evaluation of the merits and risks of an investment in Securities and the consequences of this Agreement. ESAS has considered the suitability of the Securities as an investment
in light of its own circumstances and financial condition, and ESAS is able to bear any economic risks associated with such investment. Notwithstanding the foregoing, nothing contained herein will operate to modify or limit in any respect the other
representations, warranties or covenants of EXCO or to relieve it from any obligations to ESAS for breach thereof or for the making of misleading statements or the omission of material facts in connection with the transactions contemplated herein.

violation of, any of the terms or provisions of, or constitute a default under (in each case, with or without notice or lapse of time, or both), or result, in the acceleration of, or the creation of any Lien under, any indenture, mortgage, deed of
trust, loan agreement or other

agreement, instrument, contract or other arrangement to which ESAS is a party or by which ESAS is bound or to which any of the property or assets of ESAS is subject, (ii) will not result in

default, acceleration, Lien, termination or impairment which would not reasonably be expected to result in an ESAS Material Adverse Effect. 

Section 3.8 Consents, Approvals or Waivers. No consent, approval, authorization, Order, Permit, registration or qualification of
any Third Party or with any Governmental Authority is required to be obtained or made by ESAS in connection with the execution and delivery of the Transaction Documents, the compliance by ESAS with any of the provisions hereof and thereof, or the
consummation of the transactions contemplated hereby, except for (i) such consents, approvals, authorizations, registrations or qualifications as may be required under state securities or “blue sky” Laws in connection with the

defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act) to provide reasonable assurance that information required to be disclosed by EXCO in the reports that it files or submits with the SEC is recorded, processed, summarized and reported
within the time periods specified in the SEC’s rules, regulations and forms, and is accumulated and communicated to EXCO’s management as appropriate to allow timely decisions regarding required disclosure, and (2) has disclosed, based
on its most recent evaluation of internal control over financial reporting, to EXCO’s outside auditors and the Audit Committee of the Board of Directors (A) all significant deficiencies and material weaknesses in the design or operation of
internal control over financial reporting that would reasonably be expected to adversely affect EXCO’s ability to record, process, summarize and report financial information and (B) any fraud, whether or not material, that involves
management or other employees who have a significant role in EXCO’s internal control over financial reporting, all of which information described in clauses (A) and (B) above has been disclosed by EXCO to ESAS prior to the Execution
Date. 
 (d) Any material change in internal control over financial reporting required to be disclosed in any SEC Filings has
been so disclosed. Since December 31, 2011, to the Knowledge of EXCO, neither EXCO nor any of its Subsidiaries has received any complaint, allegation, assertion or claim regarding the accounting or auditing practices, procedures, methodologies
or methods of EXCO or any of its Subsidiaries or their respective internal accounting controls relating to periods after December 31, 2011, except for any complaints, allegations, assertions or claims that have not had, and would not reasonably
be expected to have, individually or in the aggregate, an EXCO Material Adverse Effect. 
 (e) Each of the principal
executive officer of EXCO and the principal financial officer of EXCO (or each former principal executive officer of EXCO and each former principal financial officer EXCO, as applicable) has made all certifications required by Rules 13a-14 and
15d-14 under the Exchange Act and Sections 302 and 906 of the Sarbanes-Oxley Act of 2002, as amended (“SOX”), with respect to the SEC Filings, and the statements contained in such certifications are true and complete. For purposes
of this Agreement, “principal executive officer” and “principal financial officer” shall have the meanings given to such terms in SOX.

the other transactions contemplated in any of the Transaction Documents.

confidentiality obligation set forth in this Section 5.4 shall not apply to (a) Confidential Information (i) that becomes, through no violation of the provisions of this Section 5.4 by the applicable Party or such
Party’s Representatives, part of the public domain or publically available by publication or otherwise, (ii) which is obtained by the applicable Party or such Party’s Representatives from a source that is not known to it to be
prohibited from disclosing such Confidential Information to such Party or such Party’s Representatives, by any legal, fiduciary or contractual obligation of confidentiality to another Party, as evidenced by the receiving Party’s written

the Confidential Information as such disclosing Party is advised by legal counsel that it is reasonably required to disclose and shall exercise its commercially reasonable efforts to obtain reliable assurance that confidential treatment shall be
accorded such Confidential Information. The confidentiality restrictions on each Party set forth in this Section 5.4 shall terminate upon the first anniversary of the earlier of (a) Closing Date and (b) the Termination Date.

 -22- 








 
further understood and agreed that monetary damages would not be a sufficient remedy for any breach of this Section 5.4. Accordingly, it is agreed by each Party that the other Parties
shall be entitled to an injunction or injunctions (without the posting of any bond and without proof of actual damages) to prevent breaches or threatened breaches of this Section 5.4 and/or to specific performance of this
Section 5.4, and that neither a Party nor any of its Representatives may oppose the granting of such relief, provided, however, that such Party and its Representatives are entitled to dispute whether or not any Confidential

Section 5.4. “Confidential Information” means any and all information, documents, instruments, data with respect to EXCO, ESAS or of any other nature provided by or on behalf of a Party to any Representative or another

to the extent practicable, be provided to ESAS), EXCO shall not include the name of any member of the ESAS Group (that was not previously disclosed in any public disclosure) in any press release with respect to the transactions set forth herein or
in the other Transaction Documents without the prior written consent and approval of ESAS. 
 (b) From and after the
Execution Date, except as contemplated by this Section 5.5, neither EXCO, on the one hand, nor ESAS, on the other hand, shall make, and each of EXCO and ESAS shall cause each of its Affiliates not to make, any public press release or

commercially reasonable efforts to file as and when required under the HSR Act), (b) cooperate with the other Parties and furnish all information in such Party’s possession that is necessary in connection with such other Party’s
filings, (c) use commercially reasonable efforts to cause the expiration or termination of the notice or waiting periods under the HSR Act and, if applicable, any other Laws with respect to the transactions contemplated by this Agreement as
promptly as is reasonably practicable, (d) promptly inform the other Party of (and, at the other Party’s reasonable request, supply to such other Party) any communication (or other correspondence or memoranda) from or to, and any proposed
understanding or agreement with, any Governmental Authority in respect of such filings, (e) consult and cooperate with the other Party in connection with any analyses, appearances, presentations, memoranda, briefs, arguments and opinions made

contemplated by this Agreement, and (h) use commercially reasonable efforts to contest and resist any action or proceeding instituted (or threatened in writing to be instituted) by any Governmental Authority challenging the transactions
contemplated by this Agreement as in violation of any Law. If a Party or any of its Affiliates intends to participate in any meeting or discussion with any Governmental Authority with respect to such filings or the transactions contemplated by this
Agreement (other than any meetings or discussions with the SEC), it will give the other Party reasonable prior notice of, and an opportunity to participate in, such meeting or discussion. Notwithstanding anything to the contrary set forth herein, in
no event shall any Party be required to make any payment, other than filing fees, to such Governmental Authority or concede anything of value, other than such payments or concessions that are de minimis in nature and do not exceed $100,000 in
value, in the aggregate, to obtain any such consent, approval or waiver; provided, however, that if any Party is required to make a payment or concession in excess of the forgoing, the other Party may, to the extent possible, elect to
make a substitute payment or concession on the first Party’s behalf. No Party shall voluntarily extend any waiting period under the HSR Act or any competition/investment Law or enter into any agreement with any Governmental Authority to delay
or not to consummate the transactions contemplated by this Agreement, except with the prior written consent of the other Parties (such consent not to be unreasonably withheld, conditioned or delayed).

 Section 5.7 Non-Solicitation. For a period beginning on the Execution Date and
ending on the one (1) year anniversary of the earlier to occur of (a) the Termination Date or (b) the expiration of the obligations of ESAS under Section 5.18, each of EXCO, on the one hand, and ESAS, on the other hand,
shall not, without the other Party’s prior written consent, directly or indirectly solicit, encourage or otherwise induce any of the other Party’s or its Affiliates’ employees to leave their respective employment or become the
employee or contractor of the soliciting Party or its Affiliates. Notwithstanding the foregoing, nothing contained in this Section 5.7 shall prohibit the hiring or contracting for the services of any employee who has terminated his or
her employment relationship without any direct or indirect solicitation or inducement by the soliciting Party or its Affiliates. A general advertisement for employment that is not targeted at any such employee shall not constitute a breach of any
Party’s obligations under this Section 5.7. It is further understood and agreed that monetary damages would not be a sufficient remedy for any breach of this Section 5.7. Accordingly, it is agreed by each of EXCO, on the
one hand, and ESAS, on the other hand, that the other Party shall be entitled to an injunction or injunctions (without the posting of any bond and without proof of actual damages) to prevent breaches or threatened breaches of this
Section 5.7 and/or to specific performance of this Section 5.7, and that neither a Party nor any of its Affiliates may oppose the granting of such relief, provided, however, that such Party and its Affiliates
are entitled to dispute whether or not any violation of this Section 5.7 has occurred. Each Party agrees that equitable relief is not exclusive of other remedies to which the other Party may be entitled at Law or in equity for a breach
of this Section 5.7. 
 Section 5.8 Listing. EXCO shall use its commercially reasonable efforts to include all of
the Initial Shares and, when issued, the Warrant Shares for listing on the NYSE if the Common Stock is then listed on the NYSE or, if the Common Stock is not then listed on the NYSE, on the primary national securities exchange or automated quotation
system on which the Common Stock is then listed or authorized for quotation. 
 Section 5.9 Proxy Statement. 

(a) As promptly as practicable after execution of this Agreement and in any event not more than thirty (30) days after the
Execution Date, EXCO shall, in consultation with ESAS, prepare, and EXCO shall file with the SEC, preliminary proxy materials in compliance with Section 14 of the Exchange Act (the “Proxy Statement”). As promptly as practicable
after comments, if any, are received from the SEC thereon and after the furnishing by EXCO and ESAS of all information required to be contained therein, EXCO shall, in consultation with ESAS, prepare and EXCO shall file any required amendments, if
any, with the SEC. EXCO shall notify ESAS promptly of the receipt of any comments from the SEC or its staff and of any request by the SEC or its staff for amendments or supplements to the Proxy Statement or for additional information and shall
consult with ESAS regarding, and supply ESAS with copies of, all correspondence between EXCO or any of its Representatives, on the one hand, and the SEC or its staff, on the other hand, with respect to the Proxy Statement. Prior to filing or mailing
any proposed amendment of or supplement to the Proxy Statement, EXCO shall 

  
 -25- 








 
provide ESAS a reasonable opportunity to review and comment on such document. EXCO shall use its commercially reasonable efforts to have the Proxy Statement cleared by the SEC and shall
thereafter mail to the shareholders of Common Stock as promptly as possible the Proxy Statement and all other proxy materials for the Shareholder Meeting. 

(b) ESAS shall use its commercially reasonable efforts to furnish EXCO any information required to be included in the Proxy
Statement and reasonably requested from ESAS by EXCO; provided that no information that ESAS or its Affiliates has furnished, or will furnish, to EXCO shall be included in the Proxy Statement unless ESAS shall have expressly consented in
writing to such information being included in the Proxy Statement. Any information relating to ESAS furnished to EXCO in writing by ESAS expressly for use in the Proxy Statement will not contain an untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. 

(c) EXCO hereby covenants and agrees that (i) the Proxy Statement will, when filed, comply as to form in all material
respects with the applicable requirements of the Exchange Act and (ii) none of the information included or incorporated by reference in the Proxy Statement will, at the date it is first mailed to the shareholders of Common Stock or at the time
of the Shareholder Meeting or at the time of any amendment or supplement thereof, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein,
in light of the circumstances under which they are made, not misleading. 
 Section 5.10 Shareholder Approval; Meeting of
Shareholders. EXCO shall take, in accordance with applicable Law and the EXCO Organizational Documents, all action necessary to convene the Shareholder Meeting as promptly as practicable, but no later than sixty (60) days after
clearance of the proxy statement by the SEC, to submit for approval by the requisite vote of the shareholders of EXCO the Shareholder Proposals. In connection with each meeting of shareholders at which either of the Shareholder Proposals is
submitted for a vote of the shareholders of EXCO, to the fullest extent permitted by applicable Law, (i) the Board of Directors shall recommend that its shareholders vote in favor of the Shareholder Proposals, and (ii) neither the Board of
Directors nor any committee thereof shall withdraw or modify, or propose or resolve to withdraw or modify in a manner materially adverse to ESAS, the recommendation of the Board of Directors that the shareholders of EXCO vote in favor of the
Shareholder Proposals; provided that, at any time prior to obtaining such shareholder approval, the Board of Directors may withdraw such recommendation if such Board of Directors determines in good faith (after consultation with outside
counsel) that failure to take such action violates its fiduciary duties under applicable Law. EXCO shall take all lawful action to solicit from the shareholders proxies in favor of the Shareholder Proposals and take all other action necessary or
advisable to secure the vote or consent of the EXCO shareholders that are required by the rules of the NYSE and applicable Law, including, if necessary or appropriate, adjourning the Shareholder Meeting to solicit additional proxies.

beneficially own an amount in excess of such percentage solely to the extent resulting exclusively from actions or omissions taken by EXCO or under the terms of any agreements, contracts or instruments that no member of the ESAS Group is party.

(A) If EXCO’s Percentile Rank based on the one-year period preceding such anniversary is less than 50, the Incentive

 -29- 








 
and the Warrants shall be forfeited to the extent set forth in the Warrants and (2) EXCO’s right to terminate this Agreement, the retention of such amounts in the Escrow Account and the
forfeiture of the Warrants shall constitute liquidated damages hereunder, which remedy shall be the sole and exclusive remedy available to EXCO for any such ESAS Forfeiture Event, termination or failure. Each Party acknowledges and agrees that
(A) EXCO’s actual damages upon the event of such ESAS Forfeiture Event, termination or failure are difficult to ascertain with any certainty, (B) the amounts in the Escrow Account is a fair and reasonable estimate by the Parties of
such aggregate actual damages of EXCO and (C) such liquidated damages do not constitute a penalty. 
 (iii) In the event
that the Closing has occurred, on the date sixteen (16) Business Days after the Investment Obligation Test Date, if EXCO is not entitled under Section 5.18(e)(ii) to receive Monthly Fees and Incentive Payments (including all

reasonably requested by ESAS in order for ESAS to perform and provide the Services and comply with the obligations of ESAS under this Section 5.18. 

(g) In the performance of any Services by ESAS for EXCO, ESAS, its Affiliates, their employees or officers and Wilder (other
than solely in his capacity as a director or as Executive Chairman of EXCO, as applicable) shall be each deemed an independent contractor, free and clear of any dominion or control by EXCO in the manner in which said services are to be performed or
the establishment of hours of labor, and as such ESAS, its Affiliates, their employees or officers and Wilder (other than solely in his capacity as a director or as Executive Chairman of EXCO, as applicable) shall not be, and shall not represent
themselves as, an agent or employee of EXCO or its Affiliates, including for tax purposes. Notwithstanding anything herein to the contrary, ESAS retains the authority and right to direct and control all the details of ESAS’s performance of the
Services. EXCO shall have no right or authority to supervise or give directions or instructions to the employees, agents, or representatives of ESAS, its Affiliates or Wilder (other than solely in his capacity as a director or as Executive Chairman

 Section 5.20 Agreement to Invest. Subject to applicable Law, from the period after
the Closing Date through the first anniversary of the Closing Date, the ESAS Group shall purchase shares of Common Stock of EXCO through open market purchases from unaffiliated Third Parties such that (when including all or any portion of the
Initial Investment held by the ESAS Group on the Investment Obligation Test Date) shall own, directly or indirectly, beneficially or of record, as of the first anniversary of the Closing Date, shares of Common Stock of EXCO with an aggregate cost
basis (net of the aggregate cost basis of all shares of Common Stock sold by the ESAS Group during the same period) of at least fifty million dollars ($50,000,000) (such purchases, excluding the Initial Investment, the “Remaining
Investment”); provided, however, (a) ESAS, at its sole option to be exercised by the delivery of written notice to EXCO on or before the first anniversary of the Closing Date, may extend such deadline by up to three
(3) months from the first anniversary of the Closing Date (such deadline, as validly extended in accordance with this Section 5.20, the “Investment Obligation Test Date”) in the event that the ESAS Group is unable
to purchase and own such shares of Common Stock due to blackout dates (other than normal quarterly blackouts that do not exceed seventy-five (75) days with respect to the last fiscal quarter and forty-five (45) days with respect to the
first, second and third fiscal quarters) or other restrictions under applicable Laws or this Agreement, (b) ESAS shall not be required to comply with its obligations under this Section 5.20 to the extent that such compliance would

Investment, ESAS shall use commercially reasonable efforts to comply with the limitations and restrictions set forth in Rule 10b-18(b) promulgated under the Exchange Act. Within three (3) Business Days after the Investment Obligation Test Date,
ESAS shall submit a certificate stating compliance together with reasonable documentation supporting such compliance. ESAS may make open market purchases or sales of any other EXCO securities at its own discretion. 

Section 5.21 Limitation on Losses. EXCO and ESAS shall, and shall cause their respective Affiliates to, cooperate in good faith
to determine whether any transactions contemplated by this Agreement, including a Remaining Investment pursuant to Section 5.20 or the vesting, forfeiture or exercise of any Warrants pursuant to the terms of the applicable Form of
Warrant, would, or reasonably would be expected to, cause an ownership change of EXCO under Section 382 of the Code or any comparable provision of any state or local Law, limiting or restricting the utilization of net operating losses of EXCO
(collectively, an “Ownership Change”). If EXCO and ESAS agree that any such transactions would, or reasonably would be expected to cause an Ownership Change, the Parties shall use commercially reasonable efforts to negotiate a
modification mutually acceptable to EXCO and ESAS to avoid such Ownership Change.

management, Board of Directors or policies of EXCO or its Affiliates or Subsidiaries or to request, call or seek to call a meeting of the stockholders of EXCO, (C) any acquisition of any of EXCO’s or any of its Affiliates’ or
Subsidiaries’ respective loans, debt securities, equity securities or assets, or rights or options to acquire interests in any of EXCO’s or any of its Affiliates’ or Subsidiaries’ loans, debt securities, equity securities or
assets, (D) any request or proposal to waive, terminate or amend the provisions of this Section 5.22 or (E) any proposal, arrangement or other statement that is inconsistent with the terms of this Agreement, including this

Article 9, during the twenty (20) Trading Days prior to the first, second, third and fourth anniversaries of the Execution Date, ESAS shall not, and shall cause Wilder and each other member of the ESAS Group acting on behalf of, or in

express rights to terminate this Agreement under Article 9, the retention of any amounts in the Escrow Account permitted under Section 5.18(e)(ii) and the forfeiture of the Warrants pursuant to the terms thereof shall constitute

 -46- 








 
or other agents and experts reasonably incident to matters indemnified against, and the costs of prosecution, defense, preparations for defense, investigation and/or monitoring of such matters,
and the costs of enforcement of the indemnity; provided, however, that “Damages” shall not include (i) any adjustment for Taxes that may be assessed on payments under this Article 10 or for Tax benefits received
by the Indemnified Person as a consequence of any Damages, (ii) to the extent provided in Section 11.12, any loss of profits, whether actual or consequential, or other consequential damages suffered by the Party (whether on its own

(c) Any claim for indemnity under this Article 10 by (i) any member of the ESAS Group must be brought and
administered by ESAS and (ii) any member of the EXCO Group must be brought and administered by EXCO. No Indemnified Person other than ESAS and EXCO shall have any rights against either ESAS or EXCO under the terms of this Article 10

Section 10.5 Indemnification Actions. All claims for indemnification under Article 10 shall be asserted and resolved as
follows: 
 (a) For purposes of this Article 10, the term “Indemnifying Party” when used in
connection with particular Damages shall mean the Person(s) having an obligation to indemnify another Person(s) with respect to such Damages pursuant to this Article 10, and the term “Indemnified Person” when used in
connection with particular Damages shall mean a Person(s) having the right to be indemnified with respect to such Damages pursuant to this Article 10. 

(b) To make claim for indemnification, defense or reimbursement under this Article 10, EXCO or ESAS, as applicable,
shall notify the Indemnifying Party of its claim, including the specific details (including supporting documentation of the alleged Damages and such Indemnified Party’s good faith estimate of the applicable claim) of and specific basis under
this Agreement for its claim (the “Claim Notice”). 
 (c) In the event that any claim for indemnification
set forth in any Claim Notice is based upon a claim by a Third Party against the Indemnified Person (a “Third Party Claim”), EXCO or ESAS, as applicable, shall provide its Claim Notice promptly after EXCO or ESAS, as applicable, has
actual knowledge of the Third Party Claim and shall enclose a copy of all papers (if any) served with respect to the Third Party Claim; 

  
 -47- 








 
provided that the failure of any Indemnified Person to give notice of an Third Party Claim as provided in this Section 10.5 shall not relieve the Indemnifying Party of its
obligations under this Article 10 except to the extent such failure results in insufficient time being available to permit the Indemnifying Party to effectively defend against the Third Party Claim or otherwise prejudices the Indemnifying
Party’s ability to defend against the Third Party Claim. In the event that the claim for indemnification is based upon an alleged inaccuracy or breach of a representation, warranty, covenant or agreement, the Claim Notice shall specify the
representation, warranty, covenant or agreement that was allegedly inaccurate or breached. 
 (d) In the case of a claim for
indemnification based upon an Third Party Claim, the Indemnifying Party shall have thirty (30) days from its receipt of the Claim Notice to notify the Indemnified Person whether it admits or denies its obligation to defend the Indemnified
Person against such Third Party Claim under this Article 10. The Indemnified Person is authorized, prior to and during such thirty (30) day period, to file any motion, answer or other pleading that it shall deem necessary or appropriate
to protect its interests or those of the Indemnifying Party and that is not prejudicial to the Indemnifying Party. If the Indemnifying Party fails to notify the Indemnified Person within such thirty (30) day period regarding whether the
Indemnifying Party admits or denies its obligation to defend the Indemnified Person, then until such date as the Indemnifying Party admits or it is finally determined by an non-appealable judgment that such obligation exists, the Indemnified Person
may file any motion, answer or other pleading, settle any Third Party Claim or take any other action that the Indemnified Person deems necessary or appropriate to protect its interest, regardless of whether the Indemnifying Party is prejudiced or
adversely impacted by any such actions. 
 (e) If the Indemnifying Party admits its indemnity obligations under this
Article 10 with respect to any Third Party Claim, then such Indemnifying Party shall have (i) the right and obligation to diligently prosecute and control the defense, at its sole cost and expense, the Third Party Claim and
(ii) have full control of such defense and proceedings, including any compromise or settlement thereof unless the compromise or settlement includes the payment of any amount (not indemnified by the Indemnifying Party) by, the performance of any
obligation by, or the limitation of any right or benefit of, the Indemnified Person, in which event such settlement or compromise shall not be effective without the consent of the Indemnified Person, which shall not be unreasonably withheld or
delayed. If requested by the Indemnifying Party, the Indemnified Person agrees at the cost and expense of the Indemnifying Party to cooperate in contesting any Third Party Claim which the Indemnifying Party elects to contest; provided,
however, that the Indemnified Person shall not be required to bring any counterclaim or cross-complaint against any Person. The Indemnified Person may participate in, but not control, any defense or settlement of any Third Party Claim
controlled by the Indemnifying Party pursuant to this Section 10.5(e); provided that the Indemnified Person may file initial pleadings as described in the last sentence of paragraph (c) above if required by court or
procedural rules to do so within the thirty (30) day period in paragraph (c) above. An Indemnifying Party shall not, without the written consent of the Indemnified Person, settle any Third Party Claim or consent to the entry of any
judgment with respect thereto that (A) does not result in a final resolution of the Indemnified 

  
 -48- 








 
Person’s liability with respect to the Third Party Claim (including, in the case of a settlement, an unconditional written release of the Indemnified Person from all further liability in
respect of such Third Party Claim) or (B) may materially and adversely affect the Indemnified Person (other than as a result of money damages covered by the indemnity). 

(f) If the Indemnifying Party does not admit its obligation or admits its obligation but fails to diligently defend or settle
the Third Party Claim, then the Indemnified Person shall have the right, but not the obligation, to defend and control the defense against the Third Party Claim (at the sole cost and expense of the Indemnifying Party, if the Indemnified Person is
entitled to indemnification hereunder), with counsel of the Indemnified Person’s choosing, subject to the right of the Indemnifying Party to admit its obligation to indemnify the Indemnified Person and assume the defense of the Third Party
Claim at any time prior to settlement or final determination thereof. If the Indemnifying Party has not yet admitted its obligation to indemnify the Indemnified Person, the Indemnified Person shall send written notice to the Indemnifying Party of
any proposed settlement and the Indemnifying Party shall have the option for ten (10) days following receipt of such notice to (i) admit in writing its obligation for indemnification with respect to such Third Party Claim and (ii) if
its obligation is so admitted, assume the defense of the Third Party Claim, including the power to reject the proposed settlement. If the Indemnified Person settles any Third Party Claim over the objection of the Indemnifying Party after the
Indemnifying Party has timely admitted its obligation for indemnification in writing and assumed the defense of the Third Party Claim, the Indemnified Person shall be deemed to have waived any right to indemnity with respect to the Third Party
Claim. If the Indemnifying Party does not timely object to the proposed settlement, then the Indemnified Person may accept such settlement and continue to pursue indemnity for all Damages, including such settlement, from the Indemnifying Party. 

(g) In the case of a claim for indemnification not based upon a Third Party Claim, (a “Direct Claim”) shall be
asserted by giving the Indemnifying Party reasonably prompt Claim Notice thereof, but in any event not later than thirty (30) days after the Indemnified Person becomes aware of the events that gave rise to such Direct Claim. Such Claim Notice
by the Indemnified Party shall describe the Direct Claim in reasonable detail, shall include copies of all available material written evidence thereof and shall indicate the estimated amount, if reasonably practicable, of Damages that have been or
may be sustained by the Indemnified Person. The Indemnifying Party shall have sixty (60) days from its receipt of the Claim Notice to (i) cure the Damages complained of, (ii) admit its obligation to provide indemnification with
respect to such Damages or (iii) dispute the claim for such Damages. If the Indemnifying Party does not notify the Indemnified Person within such sixty (60) day period that it has cured the Damages or that it disputes the claim for such
Damages, the Indemnifying Party shall be conclusively deemed obligated to provide indemnification hereunder with respect to such Direct Claim.

 Section 11.4 Dispute Resolution. 

(a) Each Party to this Agreement agrees that any dispute, controversy, matter or claim between the Parties (each, subject to
such exceptions, a “Dispute”), that cannot be resolved among the Parties shall be resolved in accordance with procedures specified herein, which shall constitute the sole and exclusive procedures for the resolution of Disputes.
Excepting the right of a Party to seek the relief described under Section 11.4(d) below, all Disputes, whether sounding in tort, contract or otherwise, shall be resolved by binding, self-administered arbitration pursuant to the
Commercial Arbitration Rules of the American Arbitration Association (the “AAA”), and all such proceedings shall be subject to the Federal Arbitration Act; provided, however, arbitrators shall be appointed in
accordance with the provisions of this Section 11.4(a). There shall be three (3) arbitrators (“Arbitration Panel”). EXCO shall designate one arbitrator and ESAS shall designate one arbitrator, neither of whom need
be neutral but both of whom must have expertise or experience in the U.S. oil and gas industry, within thirty (30) days of the notification of a Party’s intent to proceed with arbitration hereunder. The two (2) arbitrators so
designated shall elect a third arbitrator, which shall be neutral and have experience or expertise in the U.S. oil and gas industry. If either Party fails to designate an arbitrator within the time specified or the two Parties’ arbitrators fail
to designate the neutral third arbitrator within thirty (30) days of their appointment, the remaining arbitrator(s) shall be appointed by the AAA using the listing ranking and striking method. 

(b) Each Party shall cooperate in reasonable, prompt discovery prior to presenting the case to the arbitrators. Within thirty
(30) calendar days of the appointment of the arbitrators, they shall establish (i) the scope of discovery and (ii) a limited discovery schedule. All discovery activities shall be conducted under the rules of the AAA. The award of the
Arbitration Panel shall (A) be based on the decision of a majority of the members of the Arbitration Panel, (B) be final and binding upon the Parties, (C) be issued within ninety (90) days after the submittal of the Dispute to
the AAA or as otherwise determined by the Arbitration Panel or the Parties, (D) be in writing, and (E) set forth the factual and legal bases for such award. EXCO shall pay for the expenses incurred by its designated arbitrator, and ESAS
shall pay for the expenses incurred by their designated arbitrator. The costs of the third, neutral arbitrator shall be borne as to one half by EXCO and as to the other half by ESAS. Each Party shall bear its own attorneys’ fees, subject to the
right of the Arbitration Panel to award attorneys’ fees and costs of the arbitration to any Party. As between the Parties, only damages allowed pursuant to this Agreement may be awarded and, without limiting the foregoing, arbitrators shall
have no authority to award any damages that are excluded under any express provision of the Agreement. Each Party hereby undertakes without delay to implement, perform, or comply with the provisions of any arbitral award or decision. 

(c) The site of any arbitration brought pursuant to this Section 11.4 shall be Dallas, Texas, U.S.A. 

(d) The Parties hereby agree to continue to perform their respective obligations under the Agreement while any Dispute is
pending. Notwithstanding anything to the contrary herein, any Party may proceed to any court of competent jurisdiction to (i) obtain provisional injunctive, ancillary or other equitable relief if such action is necessary to avoid irreparable
harm or to preserve the status quo pending the resolution of the Dispute in accordance with the provisions of this Section 11.4 or (ii) enter and enforce any judgment on the award rendered by the Arbitration Panel in accordance with
applicable Laws. Notwithstanding the foregoing, the arbitration of the underlying Dispute shall proceed in accordance with the terms hereof during the pendency of the proceeding to obtain such provisional injunctive, ancillary or other equitable
relief.

CONSERVATORY MEASURES OF THE RULES OF ARBITRATION OF THE AAA OR DESCRIBED IN THIS SECTION 11.4. NOTHING HEREIN SHALL AFFECT THE RIGHT OF ANY PARTY TO BRING ANY SUIT, ACTION OR PROCEEDING SEEKING TO ENFORCE ANY ARBITRAL AWARD OR OTHER
ORDER OF THE ARBITRATORS ISSUED IN AN ARBITRATION PURSUANT TO THIS SECTION 11.4 OR SEEKING ANY INTERIM OR CONSERVATORY MEASURES PURSUANT TO THE RULES OF ARBITRATION OF THE AAA AGAINST ANY PARTY IN ANY OTHER JURISDICTION PERMITTED BY LAW.

 Section 11.5 Headings and Construction. The headings and captions herein are inserted for convenience of reference only and
are not intended to govern, limit or aid in the construction of any term or provision hereof. The rights and obligations of each Party shall be determined pursuant to this Agreement. ESAS and EXCO have had the opportunity to exercise business
discretion in relation to the negotiation of the details and terms of the transaction contemplated hereby. This Agreement is the result of arm’s length negotiations from equal bargaining positions. It is the intention of the Parties that every
covenant, term and provision of this Agreement shall be construed simply according to its fair meaning and not strictly for or against any Party (notwithstanding any rule of law requiring an agreement to be strictly construed against the drafting
Party) and no consideration shall be given or presumption made, on the basis of who drafted this Agreement or any particular provision thereof, it being understood that the Parties to this Agreement are sophisticated and have had adequate
opportunity and means to exercise business discretion in relation to the negotiation of the details of the transaction contemplated hereby and retain counsel to represent their interests and to otherwise negotiate the provisions of this Agreement.

 Section 11.6 Waivers. Any failure by any Party to comply with any of its obligations, agreements or conditions herein
contained may be waived by the Party to whom such compliance is owed by the application of the express terms hereof of by an instrument signed by the Party to whom compliance is owed and expressly identified as a waiver, but not in any other manner.
Except as otherwise expressly provided herein, no waiver of, or consent to a change in or modification of, any of the provisions of this Agreement shall be deemed or shall constitute a waiver of, or consent to a change in or modification, other

consent or thereafter shall be bound by any such amendment, modification, supplement, waiver or consent effected pursuant to this Section 11.10 as it relates to ownership and transfer of the Securities, whether or not any notice, writing
or marking indicating such amendment, modification, supplement, waiver or consent appears on the Securities or is delivered to such holder. Any amendment, supplement or modification of or to any provision of this Agreement, any waiver or any
provision of this Agreement, and any consent to any departure from the terms of any provision of this Agreement shall be effective only in the specific instance and for the specific purpose for which made or given. 

Section 11.11 No Third-Person Beneficiaries. Nothing in this Agreement shall entitle any Person other than EXCO or ESAS to any
