The Credits

Section 2.01. Commitments. Subject to the terms and conditions set forth herein, each Lender that was a Lender under and as defined in the Original Credit Agreements agrees to continue the Original Loans and each Lender agrees to make Loans to the Borrower from time to time during the Availability Period in an aggregate principal amount that will not result in (a) such Lender’s Credit Exposure exceeding such Lender’s Commitment or (b) the Aggregate Credit Exposure exceeding the Aggregate Commitment. Within the foregoing limits and subject to the terms and conditions set forth herein, the Borrower may borrow, prepay and reborrow Loans.

Section 2.02. Termination and Reduction of the Aggregate Commitment.

(a) Unless previously terminated, the Aggregate Commitment shall terminate on the Maturity Date.

(b) The Borrower may at any time terminate, or from time to time reduce, the Aggregate Commitment; provided that (i) each reduction of the Aggregate Commitment shall be in an amount that is an integral multiple of $5,000,000 and not less than $10,000,000 and (ii) the Borrower shall not terminate or reduce the Aggregate Commitment if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 2.11 and Section 2.12, the Aggregate Credit Exposure would exceed the Aggregate Commitment.

(c) The Borrower shall notify the Administrative Agent of any election to terminate or reduce the Aggregate Commitment under paragraph (b) of this Section at least three Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof. Promptly following receipt of any notice, the Administrative Agent shall advise the Lenders of the contents thereof. Each notice delivered by the Borrower pursuant to this Section shall be irrevocable; provided that a notice of termination of the Aggregate Commitment delivered by the Borrower may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by the Borrower (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied. Any termination of the Aggregate Commitment shall be permanent. Each reduction of the Aggregate Commitment shall be made ratably among the Lenders in accordance with their respective Commitment.

(d) With respect to any sale, transfer or disposition of Borrowing Base Properties (other than sales, transfers or dispositions permitted under Section 7.03(a)(vi)), the Borrowing Base shall be automatically reduced by an amount equal to the value assigned to such Borrowing Base Properties by the Required Lenders at the time of such sale, transfer or other disposition.

EXCO CREDIT AGREEMENT – Page 33

Section 2.03. Additional Lenders; Increases in the Aggregate Commitment. If (a) no Default exists as of the date of such increase or would be caused by such increase, (b) the Borrower shall concurrently pay any additional fees required as a result of such increase, (c) immediately after giving effect to such increase, the Aggregate Commitment does not exceed the Borrowing Base then in effect, and (d) at the time of and immediately after giving effect to such increase, the Borrower is in pro forma compliance with the financial covenants set forth in Section 7.11 as of the last day of the most recently ended fiscal quarter for which the financial statements and compliance certificate required under Section 6.01 have been delivered to the Administrative Agent and the Lenders, the Borrower may, at any time and from time to time, increase the Aggregate Commitment to an amount not to exceed the Maximum Facility Amount by providing written notice of such increase to the Administrative Agent. Each Lender shall have the right, but not the obligation, in each such Lender’s sole discretion, to provide a portion of such increase in the Aggregate Commitment up to the portion of such increase that such Lender’s existing Commitment bears to the aggregate amount of the existing Commitments of all Lenders electing to participate in such requested increase by executing and delivering to the Borrower and the Administrative Agent a certificate substantially in the form of Exhibit F hereto (a “Lender Certificate”). In the event that within 10 Business Days of the Administrative Agent’s receipt of such written notice the existing Lenders fail to provide increases in their respective Commitments sufficient to satisfy such requested increase in the Aggregate Commitment, the Borrower may adjust the previously requested increase to reflect the increased Commitments of existing Lenders or one or more financial institutions reasonably acceptable to the Administrative Agent may become a Lender under this Agreement by executing and delivering to the Borrower and the Administrative Agent a Lender Certificate. Upon receipt by the Administrative Agent of Lender Certificates representing increases to existing Lender Commitments and/or Commitments from new Lenders as provided in this Section 2.03 in an aggregate amount equal to the requested increase (as the same may have been adjusted), (i) the Aggregate Commitment (including the Commitment of any Person that becomes a Lender by delivery of such a Lender Certificate) automatically without further action by the Borrower, the Administrative Agent or any Lender shall be increased on the effective date set forth in such Lender Certificates by the amount indicated in such Lender Certificates, (ii) the Register shall be amended to add the Commitment of each additional Lender or to reflect the increase in the Commitment of each existing Lender, and the Applicable Percentages of the Lenders shall be adjusted accordingly to reflect each additional Lender or the increase in the Commitment of each existing Lender, (iii) any such additional Lender shall be deemed to be a party in all respects to this Agreement and any other Loan Documents to which the Lenders are a party, and (iv) upon the effective date set forth in such Lender Certificate, any such Lender party to the Lender Certificate shall purchase and each existing Lender shall assign to such Lender a pro rata portion of the outstanding Credit Exposure of each of the existing Lenders such that the Lenders (including any additional Lender, if applicable) shall have the appropriate portion of the Aggregate Credit Exposure of the Lenders (based in each case on such Lender’s Applicable Percentage, as revised pursuant to this Section), and the Borrower shall have paid to the Lenders any amounts due pursuant to Section 2.17 as a result of such purchase and assignment.

EXCO CREDIT AGREEMENT – Page 34

Section 2.04. Loans and Borrowings.

(a) Each Loan shall be made as part of a Borrowing consisting of Loans made by the Lenders ratably in accordance with their respective Commitments. The failure of any Lender to make any Loan required to be made by it shall not relieve any other Lender of its obligations hereunder; provided that the Commitments of the Lenders are several and no Lender shall be responsible for any other Lender’s failure to make Loans as required.

(b) Subject to Section 2.15, each Borrowing shall be comprised entirely of ABR Loans or Eurodollar Loans as the Borrower may request in accordance herewith. Each Lender at its option may make any Eurodollar Loan by causing any domestic or foreign branch or Affiliate of such Lender to make such Loan; provided that any exercise of such option shall not affect the obligation of the Borrower to repay such Loan in accordance with the terms of this Agreement.

(c) At the commencement of each Interest Period for any Eurodollar Borrowing, such Borrowing shall be in an aggregate amount that is an integral multiple of $1,000,000 and not less than $1,000,000. At the time that each ABR Borrowing is made, such Borrowing shall be in an aggregate amount that is an integral multiple of $1,000,000 and not less than $1,000,000; provided that an ABR Borrowing may be in an aggregate amount that is equal to the entire unused balance of the Aggregate Commitment or that is required to finance the reimbursement of an LC Disbursement as contemplated by Section 2.07(e). Borrowings of more than one Type may be outstanding at the same time; provided that there shall not at any time be more than a total of eight (8) Eurodollar Borrowings outstanding.

(d) Notwithstanding any other provision of this Agreement, the Borrower shall not be entitled to request, or to elect to convert or continue, any Eurodollar Borrowing if the Interest Period requested with respect thereto would end after the Maturity Date.

Section 2.05. Requests for Borrowings. To request a Borrowing, the Borrower shall notify the Administrative Agent of such request by telephone (a) in the case of a Eurodollar Borrowing, not later than 11:00 a.m., three (3) Business Days before the date of the proposed Eurodollar Borrowing or (b) in the case of an ABR Borrowing, not later than 11:00 a.m., one (1) Business Day before the date of the proposed Borrowing; provided that any such notice of an ABR Borrowing to finance the reimbursement of an LC Disbursement as contemplated by Section 2.07(e) may be given not later than 10:00 a.m., on the date of the proposed Borrowing. Each such telephonic Borrowing Request shall be irrevocable and shall be confirmed promptly by hand delivery, telecopy or electronic mail to the Administrative Agent of a written Borrowing Request in a form approved by the Administrative Agent and signed by the Borrower. Each such telephonic and written Borrowing Request shall specify the following information in compliance with Section 2.04:

(i) the aggregate amount of the requested Borrowing;

(ii) the date of such Borrowing, which shall be a Business Day;

(iii) whether such Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing;

EXCO CREDIT AGREEMENT – Page 35

(iv) in the case of a Eurodollar Borrowing, the initial Interest Period to be applicable thereto, which shall be a period contemplated by the definition of the term “Interest Period”; and

(v) the location and number of the Borrower’s account to which funds are to be disbursed, which shall comply with the requirements of Section 2.08.

If no election as to the Type of Borrowing is specified, then the requested Borrowing shall be an ABR Borrowing. If no Interest Period is specified with respect to any requested Eurodollar Borrowing, then the Borrower shall be deemed to have selected an Interest Period of one (1) month’s duration. Promptly following receipt of a Borrowing Request in accordance with this Section, the Administrative Agent shall advise each Lender of the details thereof and of the amount of such Lender’s Loan to be made as part of the requested Borrowing.

Section 2.06. Reserved.

Section 2.07. Letters of Credit.

(a) General. Subject to the terms and conditions set forth herein, the Borrower may request the issuance of Letters of Credit for its own or the account of any Restricted Subsidiary in a form reasonably acceptable to the Administrative Agent and the Issuing Bank, at any time and from time to time during the Availability Period. In the event of any inconsistency between the terms and conditions of this Agreement and the terms and conditions of any form of letter of credit application or other agreement submitted by the Borrower to, or entered into by the Borrower with, the Issuing Bank relating to any Letter of Credit, the terms and conditions of this Agreement shall control.

(b) Notice of Issuance, Amendment, Renewal, Extension; Certain Conditions. To request the issuance of a Letter of Credit (or the amendment, renewal or extension of an outstanding Letter of Credit), the Borrower shall hand deliver or telecopy (or transmit by electronic communication, if arrangements for doing so have been approved by the Issuing Bank) to the Issuing Bank and the Administrative Agent (reasonably in advance of the requested date of issuance, amendment, renewal or extension) a notice requesting the issuance of a Letter of Credit, or identifying the Letter of Credit to be amended, renewed or extended, and specifying the date of issuance, amendment, renewal or extension (which shall be a Business Day), the date on which such Letter of Credit is to expire (which shall comply with paragraph (c) of this Section), the amount of such Letter of Credit, the name and address of the beneficiary thereof and such other information as shall be necessary to prepare, amend, renew or extend such Letter of Credit. If requested by the Issuing Bank, the Borrower also shall submit a letter of credit application on the Issuing Bank’s standard form in connection with any request for a Letter of Credit. A Letter of Credit shall be issued, amended, renewed or extended only if (and upon issuance, amendment, renewal or extension of each Letter of Credit the Borrower shall be deemed to represent and warrant that), after giving effect to such issuance, amendment, renewal or extension (i) the LC Exposure shall not exceed $100,000,000 and (ii) the Aggregate Credit Exposure shall not exceed the Aggregate Commitment.

EXCO CREDIT AGREEMENT – Page 36

(c) Expiration Date. Each Letter of Credit shall expire at or prior to the close of business on the earlier of (i) the date one year after the date of the issuance of such Letter of Credit (or, in the case of any renewal or extension thereof, one year after such renewal or extension) and (ii) the date that is five (5) Business Days prior to the Maturity Date.

(d) Participations. By the issuance of a Letter of Credit (or an amendment to a Letter of Credit increasing the amount thereof) and without any further action on the part of the Issuing Bank or the Lenders, the Issuing Bank hereby grants to each Lender, and each Lender hereby acquires from the Issuing Bank, a participation in such Letter of Credit equal to such Lender’s Applicable Percentage of the aggregate amount available to be drawn under such Letter of Credit. In consideration and in furtherance of the foregoing, each Lender hereby absolutely and unconditionally agrees to pay to the Administrative Agent, for the account of the Issuing Bank, such Lender’s Applicable Percentage of each LC Disbursement made by the Issuing Bank and not reimbursed by the Borrower on the date due as provided in paragraph (e) of this Section, or of any reimbursement payment required to be refunded to the Borrower for any reason. Each Lender acknowledges and agrees that its obligation to acquire participations pursuant to this paragraph in respect of Letters of Credit is absolute and unconditional and shall not be affected by any circumstance whatsoever, including any amendment, renewal or extension of any Letter of Credit or the occurrence and continuance of a Default or reduction or termination of the Aggregate Commitment, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever.

(e) Reimbursement. If the Issuing Bank shall make any LC Disbursement in respect of a Letter of Credit, the Borrower shall reimburse such LC Disbursement by paying to the Administrative Agent an amount equal to such LC Disbursement not later than 12:00 noon on the date that such LC Disbursement is made, if the Borrower shall have received notice of such LC Disbursement prior to 10:00 a.m. on such date, or, if such notice has not been received by the Borrower prior to such time on such date, then not later than 12:00 noon on the Business Day immediately following the day that the Borrower receives such notice; provided that the Borrower may, subject to the conditions to borrowing set forth herein, request in accordance with Section 2.05 that such payment be financed with an ABR Borrowing in an equivalent amount and, to the extent so financed, the Borrower’s obligation to make such payment shall be discharged and replaced by the resulting ABR Borrowing. If the Borrower fails to make such payment when due, the Administrative Agent shall notify each Lender of the applicable LC Disbursement, the payment then due from the Borrower in respect thereof and such Lender’s Applicable Percentage thereof. Promptly following receipt of such notice, each Lender shall pay to the Administrative Agent its Applicable Percentage of the payment then due from the Borrower, in the same manner as provided in Section 2.08 with respect to Loans made by such Lender (and Section 2.08 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Administrative Agent shall promptly pay to the Issuing Bank the amounts so received by it from the Lenders. Promptly following receipt by the Administrative Agent of any payment from the Borrower pursuant to this paragraph, the Administrative Agent shall distribute such payment to the Issuing Bank or, to the extent that Lenders have made payments pursuant to this paragraph to reimburse the Issuing Bank, then to such Lenders and the Issuing Bank as their interests may appear. Any payment made by a Lender pursuant to this paragraph to reimburse the Issuing Bank for any LC Disbursement (other than the funding of ABR Loans as contemplated above) shall not constitute a Loan and shall not relieve the Borrower of its obligation to reimburse such LC Disbursement.

EXCO CREDIT AGREEMENT – Page 37

(f) Obligations Absolute. The Borrower’s obligation to reimburse LC Disbursements as provided in paragraph (e) of this Section shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement under any and all circumstances whatsoever and irrespective of (i) any lack of validity or enforceability of any Letter of Credit or this Agreement, or any term or provision therein, (ii) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect, (iii) payment by the Issuing Bank under a Letter of Credit against presentation of a draft or other document that does not comply with the terms of such Letter of Credit, or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section, constitute a legal or equitable discharge of, or provide a right of setoff against, the Borrower’s obligations hereunder. Neither the Administrative Agent, the Lenders nor the Issuing Bank, nor any of their Related Parties, shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of the Issuing Bank; provided that the foregoing shall not be construed to excuse the Issuing Bank from liability to the Borrower to the extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by the Borrower to the extent permitted by applicable law) suffered by the Borrower that are caused by the Issuing Bank’s failure to exercise care when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof. The parties hereto expressly agree that, in the absence of gross negligence or willful misconduct on the part of the Issuing Bank (as finally determined by a court of competent jurisdiction), the Issuing Bank shall be deemed to have exercised care in each such determination. In furtherance of the foregoing and without limiting the generality thereof, the parties agree that, with respect to documents presented which appear on their face to be in substantial compliance with the terms of a Letter of Credit, the Issuing Bank may, in its sole discretion, either accept and make payment upon such documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit.

(g) Disbursement Procedures. The Issuing Bank shall, promptly following its receipt thereof, examine all documents purporting to represent a demand for payment under a Letter of Credit. The Issuing Bank shall promptly notify the Administrative Agent and the Borrower by telephone (confirmed by telecopy) of such demand for payment and whether the Issuing Bank has made or will make an LC Disbursement thereunder; provided that any failure to give or delay in giving such notice shall not relieve the Borrower of its obligation to reimburse the Issuing Bank and the Lenders with respect to any such LC Disbursement.

EXCO CREDIT AGREEMENT – Page 38

(h) Interim Interest. If the Issuing Bank shall make any LC Disbursement, then, unless the Borrower shall reimburse such LC Disbursement in full on the date such LC Disbursement is made, the unpaid amount thereof shall bear interest, for each day from and including the date such LC Disbursement is made to but excluding the date that the Borrower reimburses such LC Disbursement, at the rate per annum then applicable to ABR Loans; provided that, if the Borrower fails to reimburse such LC Disbursement when due pursuant to paragraph (e) of this Section, then Section 2.14(c) shall apply. Interest accrued pursuant to this paragraph shall be for the account of the Issuing Bank, except that interest accrued on and after the date of payment by any Lender pursuant to paragraph (e) of this Section to reimburse the Issuing Bank shall be for the account of such Lender to the extent of such payment.

(i) Replacement of the Issuing Bank. The Issuing Bank may be replaced at any time by written agreement among the Borrower, the Administrative Agent, the replaced Issuing Bank and the successor Issuing Bank. The Administrative Agent shall notify the Lenders of any such replacement of the Issuing Bank. At the time any such replacement shall become effective, the Borrower shall pay all unpaid fees accrued for the account of the replaced Issuing Bank pursuant to Section 2.13(b). From and after the effective date of any such replacement, (i) the successor Issuing Bank shall have all the rights and obligations of the Issuing Bank under this Agreement with respect to Letters of Credit to be issued thereafter and (ii) references herein to the term “Issuing Bank” shall be deemed to refer to such successor or to any previous Issuing Bank, or to such successor and all previous Issuing Banks, as the context shall require. After the replacement of an Issuing Bank hereunder, the replaced Issuing Bank shall remain a party hereto and shall continue to have all the rights and obligations of an Issuing Bank under this Agreement with respect to Letters of Credit issued by it prior to such replacement, but shall not be required to issue additional Letters of Credit.

(j) Cash Collateralization.

(i) If any Event of Default shall occur and be continuing, on the Business Day that the Borrower receives notice from the Administrative Agent or the Required Lenders (or, if the maturity of the Loans has been accelerated, Lenders with LC Exposure representing at least sixty-six and two-thirds percent (66²/3%) of the total LC Exposure) demanding the deposit of cash collateral pursuant to this paragraph, the Borrower shall deposit in the Cash Collateral Account an amount in cash equal to the total LC Exposure as of such date plus any accrued and unpaid interest thereon; provided that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become immediately due and payable, without demand or other notice of any kind, upon the occurrence of any Event of Default with respect to the Borrower described in clauses (h) or (i) of Article IX.

(ii) All cash collateral provided by Borrower or any other Credit Party pursuant to the request of the Administrative Agent in accordance with Section 2.21(c) shall be deposited in the Cash Collateral Account.

(iii) Deposits in the Cash Collateral Account made pursuant to either the foregoing paragraph (i) of this Section 2.07(j) or Section 2.21(c) shall be held by the Administrative Agent as collateral for the payment and performance of the Obligations

EXCO CREDIT AGREEMENT – Page 39

under this Agreement and Borrower hereby grants a security interest in such cash and each deposit account into which such cash is deposited to secure the Obligations under this Agreement. The Administrative Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over the Cash Collateral Account. Other than interest at the rate per annum in effect for accounts of the same type maintained with the Administrative Agent at such time and any interest earned on the investment of such deposits, which investments shall be of the type described in clause (b) of the definition of Permitted Investments and shall be made by the Administrative Agent in consultation with the Borrower (unless an Event of Default shall have occurred and be continuing, in which case, such investments shall be made at the option and sole discretion of the Administrative Agent) and at the Borrower’s risk and expense, such deposits shall not bear interest. Interest or profits, if any, on such investments shall accumulate in such account. Moneys in the Cash Collateral Account shall be applied by the Administrative Agent to reimburse the Issuing Bank for LC Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the Borrower for the LC Exposure at such time or, if the maturity of the Loans has been accelerated (but subject to the consent of Lenders with LC Exposure representing sixty-six and two-thirds percent (66²/3%) or more of the total LC Exposure), be applied to satisfy other Obligations under this Agreement.

(v) If the Borrower is required to provide cash collateral pursuant to either paragraph (i) of this Section 2.07(j) or Section 2.21(c), the amount of such cash collateral (to the extent not applied as aforesaid) shall be returned to the Borrower within three (3) Business Days after (x) in the case of cash collateral provided pursuant to paragraph (i) above, all Events of Default have been cured or waived and (y) in the case of cash collateral provided pursuant to Section 2.21(c), the date on which such cash collateral is no longer required pursuant to Section 2.21(c).

Section 2.08. Funding of Borrowings.

(a) Each Lender shall make each Loan to be made by it hereunder on the proposed date thereof by wire transfer of immediately available funds by 12:00 noon to the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders. The Administrative Agent will make such Loans available to the Borrower by promptly crediting the amounts so received, in like funds, to an account of the Borrower designated by the Borrower in the applicable Borrowing Request; provided that ABR Loans made to finance the reimbursement of an LC Disbursement as provided in Section 2.07(e) shall be remitted by the Administrative Agent to the Issuing Bank.

(b) Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any Borrowing that such Lender will not make available to the Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with paragraph (a) of this Section and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing available to the Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such

EXCO CREDIT AGREEMENT – Page 40

corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (i) in the case of such Lender, the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation or (ii) in the case of the Borrower, the interest rate applicable to ABR Loans. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender’s Loan included in such Borrowing.

Section 2.09. Interest Elections.

(a) Each Borrowing initially shall be of the Type specified in the applicable Borrowing Request and, in the case of a Eurodollar Borrowing, shall have an initial Interest Period as specified in such Borrowing Request; provided that all Borrowings on the Effective Date shall be ABR Borrowings. Thereafter, the Borrower may elect to convert such Borrowing to a different Type or to continue such Borrowing and, in the case of a Eurodollar Borrowing, may elect Interest Periods therefor, all as provided in this Section. The Borrower may elect different options with respect to different portions of the affected Borrowing, in which case each such portion shall be allocated ratably among the Lenders holding the Loans comprising such Borrowing, and the Loans comprising each such portion shall be considered a separate Borrowing.

(b) To make an election pursuant to this Section, the Borrower shall notify the Administrative Agent of such election by telephone by the time that a Borrowing Request would be required under Section 2.05 if the Borrower were requesting a Borrowing of the Type resulting from such election to be made on the effective date of such election. Each such telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by hand delivery, telecopy or electronic mail to the Administrative Agent of a written Interest Election Request in a form approved by the Administrative Agent and signed by the Borrower.

(c) Each telephonic and written Interest Election Request shall specify the following information in compliance with Section 2.04:

(i) the Borrowing to which such Interest Election Request applies and, if different options are being elected with respect to different portions thereof, the portions thereof to be allocated to each resulting Borrowing (in which case the information to be specified pursuant to clauses (iii) and (iv) below shall be specified for each resulting Borrowing);

(ii) the effective date of the election made pursuant to such Interest Election Request, which shall be a Business Day;

(iii) whether the resulting Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing; and

(iv) if the resulting Borrowing is a Eurodollar Borrowing, the Interest Period to be applicable thereto after giving effect to such election, which shall be a period contemplated by the definition of the term “Interest Period”.

EXCO CREDIT AGREEMENT – Page 41

If any such Interest Election Request requests a Eurodollar Borrowing but does not specify an Interest Period, then the Borrower shall be deemed to have selected an Interest Period of one (1) month’s duration.

(d) Promptly following receipt of an Interest Election Request, the Administrative Agent shall advise each Lender of the details thereof and of such Lender’s portion of each resulting Borrowing.

(e) If the Borrower fails to deliver a timely Interest Election Request with respect to a Eurodollar Borrowing prior to the end of the Interest Period applicable thereto, then, unless such Borrowing is repaid as provided herein, at the end of such Interest Period such Borrowing shall be converted to an ABR Borrowing. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing and the Administrative Agent, at the request of the Majority Lenders, so notifies the Borrower, then, so long as an Event of Default is continuing (i) no outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing and (ii) unless repaid, each Eurodollar Borrowing shall be converted to an ABR Borrowing at the end of the Interest Period applicable thereto.

Section 2.10. Repayment of Loans; Evidence of Debt.

(a) The Borrower hereby unconditionally promises to pay to the Administrative Agent for the account of each Lender the then unpaid principal amount of each Loan on the Maturity Date.

(b) Borrower and each surety, endorser, guarantor and other party ever liable for payment of any sums of money payable under this Agreement, jointly and severally waive presentment and demand for payment, notice of intention to accelerate the maturity, protest, notice of protest and nonpayment, as to the payments due under this Agreement or any other Loan Document and as to each and all installments hereunder and thereunder, and agree that their liability under this Agreement or any other Loan Document shall not be affected by any renewal or extension in the time of payment hereof, or in any indulgences, or by any release or change in any security for the payment of the Obligations, and hereby consent to any and all such renewals, extensions, indulgences, releases or changes.

(c) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to such Lender resulting from each Loan made by such Lender, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder.

(d) The Administrative Agent shall maintain accounts in which it shall record (i) the amount of each Loan made hereunder, the Type thereof and the Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder and (iii) the amount of any sum received by the Administrative Agent hereunder for the account of the Lenders and each Lender’s share thereof.

(e) The entries made in the accounts maintained pursuant to paragraph (d) or (e) of this Section shall be prima facie evidence of the existence and amounts of the obligations

recorded therein; provided that the failure of any Lender or the Administrative Agent to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Loans in accordance with the terms of this Agreement.

(f) Any Lender or Participant may request that Loans made by it be evidenced by a promissory note. In such event, the Borrower shall prepare, execute and deliver to such Lender or Participant a promissory note payable to the order of such Lender or Participant (or, if requested by such Lender or Participant, to such Lender or Participant and its registered assigns) and in the form attached hereto as Exhibit E. Thereafter, the Loans evidenced by such promissory note and interest thereon shall at all times (including after assignment pursuant to Section 11.04) be represented by one or more promissory notes in such form payable to the order of the payee named therein (or, if such promissory note is a registered note, to such payee and its registered assigns).

Section 2.11. Optional Prepayment of Loans.

(a) The Borrower shall have the right at any time and from time to time to prepay any Borrowing in whole and or in part, subject to prior notice in accordance with paragraph (b) of this Section; provided that any prepayment made at any time a Borrowing Base Deficiency exists shall be applied ratably to the prepayment of Borrowings to the extent required to eliminate such Borrowing Base Deficiency.

(b) The Borrower shall notify the Administrative Agent by telephone (confirmed by telecopy or electronic mail) of any prepayment hereunder (i) in the case of prepayment of a Eurodollar Borrowing, not later than 11:00 a.m. three (3) Business Days before the date of prepayment or (ii) in the case of prepayment of an ABR Borrowing, not later than 11:00 a.m. one (1) Business Day before the date of prepayment. Each such notice shall be irrevocable and shall specify the prepayment date and the principal amount of each Borrowing or portion thereof to be prepaid; provided that, if a notice of prepayment is given in connection with a conditional notice of termination or reduction of the Aggregate Commitment as contemplated by Section 2.02, then such notice of prepayment may be revoked if such notice of termination or reduction is revoked in accordance with Section 2.02. Promptly following receipt of any such notice relating to a Borrowing, the Administrative Agent shall advise the Lenders of the contents thereof. Each partial prepayment of any Borrowing shall be in an amount that would be permitted in the case of an advance of a Borrowing of the same Type as provided in Section 2.04. Each prepayment of a Borrowing shall be applied ratably to the Loans included in the prepaid Borrowing. Prepayments shall be accompanied by accrued interest to the extent required by Section 2.14.

Section 2.12. Mandatory Prepayment of Loans.

(a) Except as otherwise provided in Section 2.12(b), in the event a Borrowing Base Deficiency exists, the Borrower shall either (a) within fifteen (15) days after written notice from the Administrative Agent to the Borrower of such Borrowing Base Deficiency, by instruments satisfactory in form and substance to the Lenders, provide the Lenders with additional security consisting of Oil and Gas Interests with value and quality satisfactory to the Lenders in their sole discretion to eliminate such Borrowing Base Deficiency, or prepay, subject to the payment of any funding indemnification amounts required by Section 2.17 but without premium or penalty,

EXCO CREDIT AGREEMENT – Page 43

the principal amount of the Loans in an amount sufficient to eliminate such Borrowing Base Deficiency (or by a combination of such additional security and such prepayment eliminate such Borrowing Base Deficiency), or (b) within fifteen (15) days after written notice from the Administrative Agent to the Borrower of such Borrowing Base Deficiency, elect to prepay, subject to the payment of any funding indemnification amounts required by Section 2.17 but without premium or penalty, the principal amount of such Borrowing Base Deficiency in not more than six (6) equal monthly installments plus accrued interest thereon with the first such monthly payment being due upon the thirtieth (30^th) day after the Borrower’s receipt of notice of such Borrowing Base Deficiency.

(b) If the Borrower or any Restricted Subsidiary sells, transfers or otherwise disposes of any Borrowing Base Properties at any time (whether pursuant to a sale, transfer, or other disposition of Equity Interests of a Restricted Subsidiary permitted pursuant to Section 7.03 or otherwise), the Borrower shall prepay the Borrowings to the extent necessary to eliminate any Borrowing Base Deficiency that may exist or that may have occurred as a result of such sale, transfer or other disposition within one (1) Business Day of the date it or any Restricted Subsidiary receives the Net Cash Proceeds from such sale, transfer or other disposition and any Net Cash Proceeds in excess of the amount necessary to eliminate any such Borrowing Base Deficiency shall be used within three hundred sixty (360) days after such disposition to (i) acquire property, plant and equipment or any business entity used or useful in carrying on the business of the Borrower and its Restricted Subsidiaries and having a fair market value at least equal to the fair market value of the properties sold or otherwise disposed of or to improve or replace any existing property of the Borrower and its Restricted Subsidiaries used or useful in carrying on the business of the Borrower and its Restricted Subsidiaries or (ii) prepay the Loans in accordance with the instructions of the Borrower (unless an Event of Default exists in which event any amounts prepaid shall be applied to the Loans at the discretion of the Administrative Agent).

(c) In the event a Borrowing Base Deficiency occurs as a result of the consummation of the Marcellus Joint Venture and the reduction in the Borrowing Base pursuant to Section 3.05, the Borrower shall prepay the Loans with the Net Cash Proceeds received as a result of the consummation of the Marcellus Joint Venture on the Business Day on which it receives such Net Cash Proceeds to the extent necessary to eliminate such Borrowing Base Deficiency.

(d) In the event that the Aggregate Credit Exposure exceeds (i) the Maximum Facility Amount or (ii) the Aggregate Commitment at any time other than, with respect to this clause (ii), as a result of the occurrence of a Borrowing Base Deficiency, the Borrower shall immediately prepay, without penalty or premium but otherwise subject to any funding indemnification amounts required by Section 2.17, the principal amount of the Loans to the extent necessary to eliminate such excess.

(e) Amounts applied to the prepayment of Borrowings pursuant to this Section shall be first applied ratably to ABR Borrowings then outstanding and, upon payment in full of all outstanding ABR Borrowings, second, to Eurodollar Borrowings then outstanding, and if more than one Eurodollar Borrowing is then outstanding, to each such Eurodollar Borrowing beginning with the Eurodollar Borrowing with the least number of days remaining in the Interest Period applicable thereto and ending with the Eurodollar Borrowing with the most number of

EXCO CREDIT AGREEMENT – Page 44

days remaining in the Interest Period applicable thereto. Any prepayments pursuant to this Section shall be without penalty or premium but otherwise accompanied by accrued interest to the extent required by Section 2.14 and any funding indemnification amounts required by Section 2.17. Amounts applied to the payment of Borrowings pursuant to this Section may be reborrowed subject to and in accordance with the terms of this Agreement.

Section 2.13. Fees.

(a) The Borrower agrees to pay to the Administrative Agent, for the account of each Lender, an unused commitment fee (the “Unused Commitment Fee”) equivalent to the Applicable Rate times the daily average of the Aggregate Unused Commitments. Such Unused Commitment Fee shall be calculated on the basis of a year consisting of 360 days. The Unused Commitment Fee shall be payable in arrears on the last day of March, June, September and December of each year, commencing with the first such date to occur after the Effective Date, and on the Maturity Date for any period then ending for which the Unused Commitment Fee shall not have been theretofore paid. In the event the Aggregate Commitment terminates on any date other than the last day of March, June, September or December of any year, the Borrower agrees to pay to the Administrative Agent, for the account of each Lender, on the date of such termination, the total Unused Commitment Fee due for the period from the last day of the immediately preceding March, June, September or December, as the case may be, to the date such termination occurs.

(b) The Borrower agrees to pay (i) to the Administrative Agent for the account of each Lender a participation fee with respect to its participations in Letters of Credit, which shall accrue at the same Applicable Rate used to determine the interest rate applicable to Eurodollar Loans on the average daily amount of such Lender’s LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the Effective Date to but excluding the later of the date on which such Lender’s Commitment terminates and the date on which such Lender ceases to have any LC Exposure, and (ii) to the Issuing Bank a fronting fee, which shall accrue at the rate equal to 0.125% per annum on the average daily amount of the LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the Effective Date to but excluding the later of the date of termination of the Aggregate Commitment and the date on which there ceases to be any LC Exposure, as well as the Issuing Bank’s standard fees with respect to the issuance, amendment, renewal or extension of any Letter of Credit or processing of drawings thereunder. Participation fees and fronting fees accrued through and including the last day of March, June, September and December of each year shall be payable on the third Business Day following such last day, commencing on the first such date to occur after the Effective Date; provided that all such fees shall be payable on the date on which the Aggregate Commitment terminates and any such fees accruing after the date on which the Aggregate Commitment terminates shall be payable on demand. Any other fees payable to the Issuing Bank pursuant to this paragraph shall be payable within ten (10) days after demand. All participation fees and fronting fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

EXCO CREDIT AGREEMENT – Page 45

(c) Borrower agrees to pay to the Administrative Agent and J.P. Morgan, for their respective accounts, the fees set forth in the Fee Letter payable to the Administrative Agent and J.P. Morgan and such other fees payable in the amounts and at the times separately agreed upon between the Borrower, the Administrative Agent and J.P. Morgan.

(d) All fees payable hereunder shall be paid on the dates due, in immediately available funds, to the Administrative Agent (or to the Issuing Bank, in the case of fees payable to it) for distribution, in the case of Unused Commitment Fees and participation fees, to the Lenders. Subject to Section 11.13, fees paid shall not be refundable under any circumstances.

Section 2.14. Interest.

(a) The Loans comprising each ABR Borrowing shall bear interest at the Alternate Base Rate plus the Applicable Rate.

(b) The Loans comprising each Eurodollar Borrowing shall bear interest at the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Rate.

(c) Notwithstanding the foregoing, if any principal of or interest on any Loan or any fee or other amount payable by the Borrower hereunder is not paid when due, whether at stated maturity, upon acceleration or otherwise, such overdue amount shall bear interest, after as well as before judgment, at a rate per annum equal to (i) in the case of overdue principal of any Loan, two percent (2%) plus the rate otherwise applicable to such Loan as provided in the preceding paragraphs of this Section or (ii) in the case of any other amount, two percent (2%) plus the rate applicable to ABR Loans as provided in paragraph (a) of this Section.

(d) Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan and upon termination of the Aggregate Commitment and on the Maturity Date; provided that (i) interest accrued pursuant to paragraph (c) of this Section shall be payable on demand, (ii) in the event of any repayment or prepayment of any Loan (other than a prepayment of an ABR Loan prior to the end of the Availability Period at a time when no Borrowing Base Deficiency exists), accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment and (iii) in the event of any conversion of any Eurodollar Loan prior to the end of the current Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion.

(e) All interest hereunder shall be computed on the basis of a year of 360 days, except that interest computed by reference to the Alternate Base Rate at times when the Alternate Base Rate is based on the Prime Rate shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and in each case shall be payable for the actual number of days elapsed (including the first day but excluding the last day). The applicable Alternate Base Rate, Adjusted LIBO Rate or LIBO Rate shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error.

EXCO CREDIT AGREEMENT – Page 46

Section 2.15. Alternate Rate of Interest. If prior to the commencement of any Interest Period for a Eurodollar Borrowing:

(a) the Administrative Agent determines (which determination shall be conclusive absent manifest error) that adequate and reasonable means do not exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period; or

(b) the Administrative Agent is advised by the Majority Lenders that the Adjusted LIBO Rate or the LIBO Rate, as applicable, for such Interest Period will not adequately and fairly reflect the cost to such Lenders (or Lender) of making or maintaining their Loans (or its Loan) included in such Borrowing for such Interest Period;

then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by telephone, telecopy or electronic mail as promptly as practicable thereafter and, until the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective, and (ii) if any Borrowing Request requests a Eurodollar Borrowing, such Borrowing shall be made as an ABR Borrowing.

Section 2.16. Increased Costs.

(a) If any Change in Law shall:

(i) impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender (except any such reserve requirement reflected in the Adjusted LIBO Rate) or the Issuing Bank; or

(ii) impose on any Lender or the Issuing Bank or the London interbank market any other condition affecting this Agreement or Eurodollar Loans made by such Lender or any Letter of Credit or participation therein;

and the result of any of the foregoing shall be to increase the cost to such Lender of making or maintaining any Eurodollar Loan (or of maintaining its obligation to make any such Loan) or to increase the cost to such Lender or the Issuing Bank of participating in, issuing or maintaining any Letter of Credit or to reduce the amount of any sum received or receivable by such Lender or the Issuing Bank hereunder (whether of principal, interest or otherwise), then the Borrower will pay to such Lender or the Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or the Issuing Bank, as the case may be, for such additional costs incurred or reduction suffered.

(b) If any Lender or the Issuing Bank determines that any Change in Law regarding capital requirements has or would have the effect of reducing the rate of return on such Lender’s or the Issuing Bank’s capital or on the capital of such Lender’s or the Issuing Bank’s holding company, if any, as a consequence of this Agreement or the Loans made by, or participations in Letters of Credit held by, such Lender, or the Letters of Credit issued by the Issuing Bank, to a level below that which such Lender or the Issuing Bank or such Lender’s or the Issuing Bank’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or the Issuing Bank’s policies and the policies of such Lender’s or the Issuing

EXCO CREDIT AGREEMENT – Page 47

Bank’s holding company with respect to capital adequacy), then from time to time the Borrower will pay to such Lender or the Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or the Issuing Bank or such Lender’s or the Issuing Bank’s holding company for any such reduction suffered.

(c) A certificate of a Lender or the Issuing Bank setting forth (i) the amount or amounts reasonably necessary to compensate such Lender or the Issuing Bank or its holding company, as the case may be, as specified in paragraph (a) or (b) of this Section, (ii) the factual basis for such compensation and (iii) the manner in which such amount or amounts were calculated shall be delivered to the Borrower. Such certificate shall be conclusive absent manifest error. The Borrower shall pay such Lender or the Issuing Bank, as the case may be, the amount shown as due on any such certificate within 10 days after receipt thereof.

(d) Failure or delay on the part of any Lender or the Issuing Bank to demand compensation pursuant to this Section shall not constitute a waiver of such Lender’s or the Issuing Bank’s right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender or the Issuing Bank pursuant to this Section for any increased costs or reductions incurred more than one hundred eighty (180) days prior to the date that such Lender or the Issuing Bank, as the case may be, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or the Issuing Bank’s intention to claim compensation therefor; provided further that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 180-day period referred to above shall be extended to include the period of retroactive effect thereof.

Section 2.17. Break Funding Payments. In the event of (a) the payment of any principal of any Eurodollar Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto, (c) the failure to borrow, convert, continue or prepay any Eurodollar Loan on the date specified in any notice delivered pursuant hereto (regardless of whether such notice may be revoked under Section 2.11(b) and is revoked in accordance therewith), (d) the assignment of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto as a result of a request by the Borrower pursuant to Section 2.20, then, in any such event, the Borrower shall compensate each Lender for the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest which would have accrued on the principal amount of such Loan had such event not occurred, at the Adjusted LIBO Rate that would have been applicable to such Loan, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest which would accrue on such principal amount for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the eurodollar market. A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section shall be delivered to the Borrower within one hundred eighty (180) days after such Lender incurs such loss, cost or expense and shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within ten (10) days after receipt thereof.

EXCO CREDIT AGREEMENT – Page 48

Section 2.18. Taxes.

(a) Any and all payments by or on account of any obligation of the Borrower hereunder shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if the Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section) the Administrative Agent, Lender or Issuing Bank (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

(b) In addition, the Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c) The Borrower shall indemnify the Administrative Agent, each Lender and the Issuing Bank, within 10 days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent, such Lender or the Issuing Bank, as the case may be, on or with respect to any payment by or on account of any obligation of the Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate delivered to the Borrower by a Lender or the Issuing Bank, or by the Administrative Agent on its own behalf or on behalf of a Lender or the Issuing Bank, setting forth (i) the amount of such payment or liability reasonably necessary to compensate the Administrative Agent, such Lender or the Issuing Bank, as the case may be, (ii) the factual basis for such compensation and (iii) the manner in which such amount or amounts were calculated, shall be conclusive absent manifest error.

(d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(e) Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which the Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Borrower as will permit such payments to be made without withholding or at a reduced rate.

EXCO CREDIT AGREEMENT – Page 49

(f) If the Administrative Agent or a Lender determines, in its sole discretion, that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified by the Borrower or with respect to which the Borrower have paid additional amounts pursuant to this Section 2.18, it shall pay over such refund to the Borrower (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section 2.18 with respect to the Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of the Administrative Agent or such Lender and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund); provided, that the Borrower, upon the request of the Administrative Agent or such Lender, agrees to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent or such Lender in the event the Administrative Agent or such Lender is required to repay such refund to such Governmental Authority. This Section shall not be construed to require the Administrative Agent or any Lender to make available its tax returns (or any other information relating to its taxes which it deems confidential) to the Borrower or any other Person.

Section 2.19. Payments Generally; Pro Rata Treatment; Sharing of Set-offs.

(a) The Borrower shall make each payment required to be made by it hereunder (whether of principal, interest, fees or reimbursement of LC Disbursements, or of amounts payable under Section 2.16, Section 2.17 or Section 2.18, or otherwise) prior to 12:00 noon on the date when due, in immediately available funds, without set-off or counterclaim. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at its offices at JPMorgan Chase Bank, N.A., Mail Code IL1-0010, 10 South Dearborn, 7^th Floor, Chicago, Illinois 60603-2003, except payments to be made directly to the Issuing Bank as expressly provided herein and except that payments pursuant to Section 2.16, Section 2.17, Section 2.18 and Section 11.03 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments hereunder shall be made in Dollars.

(b) If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, unreimbursed LC Disbursements, interest, fees and other Obligations then due hereunder, such funds shall be applied (i) first, towards payment of interest and fees then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, towards payment of principal and unreimbursed LC Disbursements then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal and unreimbursed LC Disbursements then due to such parties; provided that in the event such funds are received by and available to the Administrative Agent as a result of the exercise of any rights and remedies with respect to any collateral under the Security Instruments, the parties entitled to a ratable share of such funds pursuant to the foregoing clause (ii) and the determination of each

EXCO CREDIT AGREEMENT – Page 50

parties’ ratable share shall include, on a pari passu basis, (x) the Lender Counterparties with respect to Lender Hedging Obligations then due and owing to each Lender Counterparty by any Credit Party as a result of the early termination of any transactions under any Swap Agreements (after giving effect to any netting agreements) and (y) any Lender or any of its Affiliates with respect to Cash Management Obligations then due and owing to such Lender or any of its Affiliates by any Credit Party.

(c) If any Lender shall, by exercising any right of set-off or counterclaim or otherwise (including any right of set-off exercised with respect to a Swap Agreement), obtain payment in respect of any principal of or interest on any of its Loans or participations in LC Disbursements resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and participations in LC Disbursements and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Loans and participations in LC Disbursements of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and participations in LC Disbursements; provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this paragraph shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or participations in LC Disbursements to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this paragraph shall apply). The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

(d) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders or the Issuing Bank hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders or the Issuing Bank, as the case may be, the amount due. In such event, if the Borrower have not in fact made such payment, then each of the Lenders or the Issuing Bank, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or Issuing Bank with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.

(e) If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.07(d), Section 2.07(e), Section 2.08(b), Section 2.19(d) or Section 11.03(c), then the Administrative Agent may, in its discretion and notwithstanding any contrary provision hereof

EXCO CREDIT AGREEMENT – Page 51

(i) apply any amounts thereafter received by the Administrative Agent for the account of such Lender and for the benefit of the Administrative Agent or the Issuing Bank to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid, and/or (ii) hold any such amounts in a segregated account as cash collateral for, and application to, any future funding obligations of such Lender under such Sections, in the case of each of (i) and (ii) above, in any order as determined by the Administrative Agent in its discretion.

Section 2.20. Mitigation Obligations; Replacement of Lenders.

(a) If any Lender requests compensation under Section 2.16, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.18, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or Affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.16 or Section 2.18, as the case may be, in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b) If any Lender requests compensation under Section 2.16, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.18, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 11.04), all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (i) the Borrower shall have received the prior written consent of the Administrative Agent (and if a Commitment is being assigned, the Issuing Bank), which consent shall not unreasonably be withheld, (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans, participations in LC Disbursements, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under Section 2.16 or payments required to be made pursuant to Section 2.18, such assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

(c) If (i) in connection with any proposed amendment, modification, termination, waiver or consent with respect to any of the provisions of this Agreement or any other Loan Document that requires approval of all of the Lenders under Section 11.02, the consent of Super-Majority Lenders shall have been obtained but the consent of one or more of such other Lenders (each a “Non-Consenting Lender”) whose consent is required has not been obtained or (ii) a Lender is a Defaulting Lender; then, in each case, the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, elect to replace such Non-

EXCO CREDIT AGREEMENT – Page 52

Consenting Lender or Defaulting Lender, as the case may be, as a Lender party to this Agreement in accordance with and subject to the restrictions contained in, and consents required by Section 11.04; provided that (x) the Borrower shall have received the prior written consent of the Administrative Agent (and if a Commitment is being assigned, the Issuing Bank), which consent shall not unreasonably be withheld, and (y) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and participations in LC Disbursements, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts). A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a consent by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply or, in the case of a Defaulting Lender, such Lender is no longer a Defaulting Lender.

Section 2.21. Defaulting Lenders. Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a Defaulting Lender, then the following provisions shall apply for so long as such Lender is a Defaulting Lender:

(a) the fees described in Section 2.13(a) shall cease to accrue on the unfunded portion of the Commitment of such Defaulting Lender;

(b) the Commitment and Credit Exposure of such Defaulting Lender shall not be included in determining whether all Lenders, Super-Majority Lenders, Required Lenders, or the Majority Lenders have taken or may take any action hereunder (including any consent to any amendment or waiver pursuant to Section 11.02), provided that (i) any waiver, consent, amendment or modification requiring the consent of all Lenders shall require the consent of such Defaulting Lender (except in respect of any increases in the Borrowing Base or the Maximum Facility Amount), (ii) any waiver, consent, amendment or modification requiring the consent of each affected Lender which affects such Defaulting Lender differently than other affected Lenders shall require the consent of such Defaulting Lender, and (iii) the Commitment of such Defaulting Lender may not be increased or extended without the consent of such Defaulting Lender.

(i) all or any part of such LC Exposure shall be reallocated among the non-Defaulting Lenders in accordance with their respective Applicable Percentages but only to the extent (x) the sum of all non-Defaulting Lenders’ Credit Exposures plus such Defaulting Lender’s LC Exposure does not exceed the total of all non-Defaulting Lenders’ Commitments and (y) the conditions set forth in Section 5.02 are satisfied at such time;

(ii) if the reallocation described in clause (i) above cannot, or can only partially, be effected, the Borrower shall, within one (1) Business Day following notice by the Administrative Agent, cash collateralize such Defaulting Lender’s LC Exposure (after giving effect to any partial reallocation pursuant to clause (i) above) in accordance with the procedures set forth in Section 2.07(j) for so long as such LC Exposure is outstanding;

EXCO CREDIT AGREEMENT – Page 53

(iii) if the Borrower cash collateralizes any portion of such Defaulting Lender’s LC Exposure pursuant to this Section 2.21(c), the Borrower shall not be required to pay any fees to such Defaulting Lender pursuant to Section 2.13(b) with respect to such Defaulting Lender’s LC Exposure during the period such Defaulting Lender’s LC Exposure is cash collateralized;

(iv) if the LC Exposure of the non-Defaulting Lenders is reallocated pursuant to this Section 2.21(c), then the fees payable to the Lenders pursuant to Section 2.13(a) and Section 2.13(b) shall be adjusted in accordance with such non-Defaulting Lenders’ Applicable Percentages; and

(v) if any Defaulting Lender’s LC Exposure is neither cash collateralized nor reallocated pursuant to Section 2.21(c), then, without prejudice to any rights or remedies of the Issuing Bank or any Lender hereunder, all participation fees payable under Section 2.13(b) with respect to such Defaulting Lender’s LC Exposure shall be payable to the Issuing Bank until such LC Exposure is cash collateralized and/or reallocated;

(d) so long as any Lender is a Defaulting Lender, the Issuing Bank shall not be required to issue, amend, renew or extend any Letter of Credit, unless it is satisfied that the related exposure will be 100% covered by the Commitments of the non-Defaulting Lenders and/or cash collateral will be provided by the Borrower in accordance with Section 2.21(c); and

(e) the Borrower shall have the right, to the extent permitted by applicable law, to set-off any amounts owed to it or any of its Restricted Subsidiaries by any Defaulting Lender in respect of deposit account liabilities against amounts due by the Borrower to such Defaulting Lender under this Agreement; provided that the amount of such set-off shall not exceed the amount of such Defaulting Lender’s Credit Exposure and any accrued and unpaid interest with respect thereto.

In the event that the Administrative Agent, the Borrower, and the Issuing Bank each agrees that a Defaulting Lender has adequately remedied all matters that caused such Lender to be a Defaulting Lender, then the LC Exposure of the Lenders shall be readjusted to reflect the inclusion of such Lender’s Commitment and on such date such Lender shall purchase at par such of the Loans of the other Lenders as the Administrative Agent shall determine may be necessary in order for such Lender to hold such Loans in accordance with its Applicable Percentage.

Article III

Borrowing Base

Section 3.01. Reserve Report; Proposed Borrowing Base. During the period from the Effective Date until the first Redetermination after the Effective Date, the Borrowing Base shall be $1,300,000,000 (the “Initial Borrowing Base”). As soon as available and in any event by March 1 and September 1 of each year, beginning September 1, 2010, the Borrower shall deliver to the Administrative Agent and each Lender a Reserve Report, prepared as of the immediately

EXCO CREDIT AGREEMENT – Page 54

preceding December 31 and June 30, respectively, in form and substance reasonably satisfactory to the Administrative Agent and prepared by an Approved Petroleum Engineer (or, in the case of the Reserve Report due on September 1 of each year, by either an Approved Petroleum Engineer or petroleum engineers employed by the Borrower), said Reserve Report to utilize economic and pricing parameters established from time to time by the Administrative Agent, together with such other information, reports and data concerning the value of the Borrowing Base Properties as the Administrative Agent shall deem reasonably necessary to determine the value of such Borrowing Base Properties. Simultaneously with the delivery to the Administrative Agent and the Lenders of each Reserve Report, the Borrower shall submit to the Administrative Agent and each Lender the Borrower’s requested amount of the Borrowing Base as of the next Redetermination Date. Promptly after the receipt by the Administrative Agent of such Reserve Report and Borrower’s requested amount for the Borrowing Base, the Administrative Agent shall submit to the Lenders a recommended amount of the Borrowing Base to become effective for the period commencing on the next Redetermination Date.

Section 3.02. Scheduled Redeterminations of the Borrowing Base; Procedures and Standards. Based in part on the Reserve Reports made available to the Administrative Agent and the Lenders pursuant to Section 3.01, the Lenders shall redetermine the Borrowing Base on or prior to the next Redetermination Date (or such date promptly thereafter as reasonably possible based on the engineering and other information available to the Lenders). Any Borrowing Base which becomes effective as a result of any Redetermination shall be subject to the following restrictions: (a) such Borrowing Base shall not exceed the Maximum Facility Amount, (b) to the extent such Borrowing Base represents an increase in the Borrowing Base in effect prior to such Redetermination, such Borrowing Base must be approved by all Lenders, and (c) to the extent such Borrowing Base represents a decrease in the Borrowing Base in effect prior to such Redetermination or a reaffirmation of such prior Borrowing Base, such Borrowing Base must be approved by the Administrative Agent and Required Lenders. If a redetermined Borrowing Base is not approved by the Administrative Agent and Required Lenders within twenty (20) days after the submission to the Lenders by the Administrative Agent of its recommended Borrowing Base pursuant to Section 3.01, or by all Lenders within such twenty (20) day period in the case of any increase in the Borrowing Base, the Administrative Agent shall notify each Lender that the recommended Borrowing Base, as the case may be, has not been approved and request that each Lender submit to the Administrative Agent within ten (10) days thereafter its proposed Borrowing Base. Promptly following the tenth (10^th) day after the Administrative Agent’s request for each Lender’s proposed Borrowing Base, the Administrative Agent shall determine the Borrowing Base for such Redetermination by calculating the highest Borrowing Base then acceptable to the Administrative Agent and a number of Lenders sufficient to constitute Required Lenders (or all Lenders in the case of an increase in the Borrowing Base). Each Redetermination shall be made by the Lenders in their sole discretion, but based on the Administrative Agent’s and such Lender’s usual and customary procedures for evaluating Oil and Gas Interests as such exist at the time of such Redetermination, and including adjustments to reflect the effect of any Swap Agreements of the Borrower and the Restricted Subsidiaries as such exist at the time of such Redetermination. The Borrower acknowledges and agrees that each Redetermination shall be based upon the loan collateral value which the Administrative Agent and each Lender in its sole discretion (using such methodology, assumptions and discount rates as the Administrative Agent and such Lender customarily uses in assigning collateral value to Oil and Gas Interests) assigns to the Borrowing Base Properties at the time in question and

EXCO CREDIT AGREEMENT – Page 55

based upon such other credit factors consistently applied (including, without limitation, the assets, liabilities, cash flow, business, properties, prospects, management and ownership of the Credit Parties) as the Administrative Agent and such Lender customarily considers in evaluating similar oil and gas credits. It is expressly understood that the Administrative Agent and Lenders shall have no obligation to designate the Borrowing Base at any particular amounts, except in the exercise of their discretion, whether in relation to the Maximum Facility Amount or otherwise. If the Borrower does not furnish all information, reports and data required to be delivered by any date specified in this Article III, unless such failure is not the fault of the Borrower, the Administrative Agent and Lenders may nonetheless designate the Borrowing Base at any amounts which the Administrative Agent and all Lenders or Required Lenders, as the case may be, in their reasonable discretion determine and may redesignate the Borrowing Base from time to time thereafter until the Administrative Agent and the Lenders receive all such information, reports and data, whereupon the Administrative Agent and all Lenders or Required Lenders, as the case may be, shall designate a new Borrowing Base, as described above.

Section 3.03. Special Redeterminations. In addition to Scheduled Redeterminations, the Borrower shall be permitted to request a Special Redetermination of the Borrowing Base once between each Scheduled Redetermination and the Required Lenders shall be permitted to request a Special Redetermination at any time. Any request by Borrower pursuant to this Section 3.03 shall be submitted to the Administrative Agent and each Lender and at the time of such request (or within twenty (20) days thereafter in the case of the Reserve Report) Borrower shall (1) deliver to the Administrative Agent and each Lender a Reserve Report prepared as of a date prior to the date of such request that is reasonably acceptable to the Administrative Agent and such other information which the Administrative Agent shall reasonably request, and (2) notify the Administrative Agent and each Lender of the Borrowing Base requested by Borrower in connection with such Special Redetermination. Any request by Required Lenders for a Special Redetermination pursuant to this Section 3.03 shall be submitted to the Administrative Agent and the Borrower. Any Special Redetermination shall be made by the Administrative Agent and Lenders in accordance with the procedures and standards set forth in Section 3.02; provided that no Reserve Report is required to be delivered to the Administrative Agent or the Lenders in connection with any Special Redetermination requested by the Required Lenders pursuant to this Section 3.03.

Section 3.04. Notice of Redetermination. Promptly following any Redetermination of the Borrowing Base, the Administrative Agent shall notify the Borrower of the amount of the redetermined Borrowing Base, which Borrowing Base shall be effective as of the date specified in such notice, and such Borrowing Base shall remain in effect for all purposes of this Agreement until the next Redetermination.

Section 3.05. Mandatory Borrowing Base Reduction. Upon the consummation of the Marcellus Joint Venture in accordance with the terms of this Agreement, the Borrowing Base then in effect shall be reduced by $100,000,000 and shall remain at such amount until the earlier of (i) the next Redetermination of the Borrowing Base and (ii) the date such Borrowing Base is otherwise reduced pursuant to the terms of this Agreement.

Article IV

Representations and Warranties

Each Credit Party represents and warrants to the Lenders that (it being understood and agreed that with respect to the Effective Date such representations and warranties are deemed to be made concurrently with and after giving effect to the consummation of the Transactions):

Section 4.01. Organization; Powers. Each Credit Party is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization, has all requisite power and authority to carry on its business as now conducted and, except where the failure to do so, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect, is qualified to do business in, and is in good standing in, every jurisdiction where such qualification is required.

Section 4.02. Authorization; Enforceability. The Transactions are within each Credit Party’s corporate, limited liability company or partnership powers and have been duly authorized by all necessary corporate, limited liability company or partnership and, if required, stockholder action. This Agreement has been duly executed and delivered by each Credit Party and constitutes a legal, valid and binding obligation of each Credit Party, enforceable in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other laws affecting creditors’ rights generally and subject to general principles of equity, regardless of whether considered in a proceeding in equity or at law.

Section 4.03. Governmental Approvals; No Conflicts. The Transactions (a) do not require any consent or approval of, registration or filing with, or any other action by, any Governmental Authority, except such as have been obtained or made and are in full force and effect and, after the Effective Date, the filing of this Agreement and related Loan Documents by the Borrower with, and other required disclosures required by, the Securities and Exchange Commission pursuant to the requirements of the Securities Exchange Act of 1934, as amended, (b) will not violate any applicable law or regulation or the charter, by-laws or other Organizational Documents of the Borrower or any Restricted Subsidiary or any order of any Governmental Authority, (c) will not violate or result in a default under any indenture, agreement or other instrument evidencing Material Indebtedness or a Material Sales Contract binding upon the Borrower or any Restricted Subsidiary or any of their respective assets, or give rise to a right thereunder to require any payment to be made by the Borrower or any Restricted Subsidiary, and (d) will not result in the creation or imposition of any Lien on any asset of the Borrower or any Restricted Subsidiary not otherwise permitted under Section 7.02.

(a) The Borrower has heretofore furnished to the Lenders the consolidated balance sheet and related statements of income and cash flows of the Borrower and its Consolidated Subsidiaries (i) as of and for each of the fiscal years ended December 31, 2008, reported on by KPMG LLP, independent public accountants, and December 31, 2009, reported on by KPMG LLP, independent public accountants and (ii) as of and for the calendar months and portion of the fiscal year ended February 28, 2010, setting forth in comparative form the figures for the

EXCO CREDIT AGREEMENT – Page 57

corresponding period of (or, in the case of the balance sheet, as of the end of) the previous fiscal year, all certified by a Responsible Officer. Such financial statements present fairly, in all material respects, the financial position and results of operations and cash flows of the Borrower and its Consolidated Subsidiaries as of such dates and for such periods in accordance with GAAP, subject to year-end audit adjustments and the absences of footnotes, in the case of the statements referred to in clause (ii).

(b) Since December 31, 2009, there has been no material adverse change in the business, assets, operations, prospects or condition, financial or otherwise, of the Borrower and its Restricted Subsidiaries, taken as a whole (it being understood that changes in commodity prices for Hydrocarbons affecting the oil and gas industry as a whole do not constitute a material adverse change).

Section 4.05. Properties.

(a) Except as otherwise provided in Section 4.15 with respect to proved reserves included in the Oil and Gas Interests of the Borrower and each Restricted Subsidiary, the Borrower and each Restricted Subsidiary has good title to, or valid leasehold interests in, all such real and personal property material to its business, except for minor defects in title that do not interfere with its ability to conduct its business as currently conducted or to utilize such properties for their intended purposes.

(b) The Borrower and each Restricted Subsidiary owns, or is licensed to use, all trademarks, tradenames, copyrights, patents and other intellectual property material to its business, and the use thereof by the Borrower and such Restricted Subsidiaries, as the case may be, does not infringe upon the rights of any other Person, except for any such infringements that, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect.

Section 4.06. Litigation and Environmental Matters.

(a) There are no actions, suits, investigations or proceedings by or before any arbitrator or Governmental Authority pending against or, to the knowledge of the Borrower, threatened against or affecting the Borrower or any Restricted Subsidiary, (i) as to which there is a reasonable possibility of an adverse determination and that, if adversely determined, could reasonably be expected, individually or in the aggregate, to result in a Material Adverse Effect (other than the Disclosed Matters) or (ii) that involve this Agreement or the Transactions.

(b) Except for the Disclosed Matters and except with respect to any other matters that, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect, neither the Borrower nor any Restricted Subsidiary to the Borrower’s knowledge (i) has failed to comply with any Environmental Law or to obtain, maintain or comply with any permit, license or other approval required under any Environmental Law, (ii) has become subject to any Environmental Liability, (iii) has received notice of any claim with respect to any Environmental Liability or (iv) knows of any basis for any Environmental Liability.

EXCO CREDIT AGREEMENT – Page 58

(c) Since the date of this Agreement, there has been no change in the status of the Disclosed Matters that, individually or in the aggregate, has resulted in, or materially increased the likelihood of, a Material Adverse Effect.

Section 4.07. Compliance with Laws and Agreements. The Borrower and each Restricted Subsidiary is in compliance with all laws, regulations and orders of any Governmental Authority applicable to it or its property and all indentures, agreements and other instruments binding upon it or its property, except where the failure to do so, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect. No Default has occurred and is continuing.

Section 4.08. Investment Company Status. Neither the Borrower nor any Restricted Subsidiary is an “investment company” as defined in, or subject to regulation under, the Investment Company Act of 1940.

Section 4.09. Taxes. The Borrower and each Restricted Subsidiary has timely filed or caused to be filed all Tax returns and reports required to have been filed and has paid or caused to be paid all Taxes required to have been paid by it, except (a) Taxes that are being contested in good faith by appropriate proceedings and for which the Borrower or such Restricted Subsidiary, as applicable, has set aside on its books adequate reserves or (b) to the extent that the failure to do so could not reasonably be expected to result in a Material Adverse Effect.

Section 4.10. ERISA. No ERISA Event has occurred or is reasonably expected to occur that, when taken together with all other such ERISA Events for which liability is reasonably expected to occur, could reasonably be expected to result in a Material Adverse Effect. The present value of all accumulated benefit obligations under each Plan (based on the assumptions used for purposes of FASB Statement 87) did not, as of the date of the most recent financial statements reflecting such amounts, exceed by more than $5,000,000 the fair market value of the assets of such Plan, and the present value of all accumulated benefit obligations of all underfunded Plans (based on the assumptions used for purposes of FASB Statement 87) did not, as of the date of the most recent financial statements reflecting such amounts, exceed by more than $5,000,000 the fair market value of the assets of all such underfunded Plans.

Section 4.11. Disclosure. The Borrower has disclosed to the Lenders all agreements, instruments and corporate or other restrictions to which it or any Restricted Subsidiary is subject, and all other matters known to it, that, individually or in the aggregate, could reasonably be expected to result in a Material Adverse Effect. None of the other reports, financial statements, certificates or other information furnished by or on behalf of the Borrower or any Restricted Subsidiary to the Administrative Agent or any Lender in connection with the negotiation of this Agreement or delivered hereunder (as modified or supplemented by other information so furnished) contains any material misstatement of fact or omits to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided that, with respect to the Projections, the Borrower represents only that such information was prepared in good faith based on assumptions believed to be reasonable at the time.

EXCO CREDIT AGREEMENT – Page 59

Section 4.12. Labor Matters. There are no strikes, lockouts or slowdowns against the Borrower or any of its Restricted Subsidiaries pending or, to the knowledge of the Borrower, threatened that could reasonably be expected to have a Material Adverse Effect. The hours worked by and payments made to employees of the Borrower and its Restricted Subsidiaries have not been in violation of the Fair Labor Standards Act or any other Law dealing with such matters to the extent that such violation could reasonably be expected to have a Material Adverse Effect.

Section 4.13. Capitalization and Credit Party Information. Schedule 4.13 lists, as of the Effective Date (a) each Subsidiary that is an Unrestricted Subsidiary, (b) for the Borrower, its full legal name, its jurisdiction of organization and its federal tax identification number, and (c) for each Restricted Subsidiary its full legal name, its jurisdiction of organization, its federal tax identification number, the number of shares of capital stock or other Equity Interests outstanding and the owner(s) of such Equity Interests.

Section 4.14. Margin Stock. Neither the Borrower nor any Restricted Subsidiary is engaged principally, or as one of its important activities, in the business of extending credit for the purpose of purchasing or carrying margin stock (within the meaning of Regulation U issued by the Board), and no part of the proceeds of any Loan will be used to purchase or carry any margin stock or to extend credit to others for the purpose of purchasing or carrying margin stock.

Section 4.15. Oil and Gas Interests. Each Credit Party has good and defensible title to all proved reserves included in the Oil and Gas Interests (for purposes of this Section 4.15, “proved Oil and Gas Interests”) described in the most recent Reserve Report provided to the Administrative Agent, free and clear of all Liens except Liens permitted pursuant to Section 7.02. All such proved Oil and Gas Interests are valid, subsisting, and in full force and effect, and all rentals, royalties, and other amounts due and payable in respect thereof have been duly paid. Without regard to any consent or non-consent provisions of any joint operating agreement covering any Credit Party’s proved Oil and Gas Interests, such Credit Party’s share of (a) the costs for each proved Oil and Gas Interest described in the Reserve Report is not materially greater than the decimal fraction set forth in the Reserve Report, before and after payout, as the case may be, and described therein by the respective designations “working interests,” “WI,” “gross working interest,” “GWI,” or similar terms (except in such cases where there is a corresponding increase in the net revenue interest), and (b) production from, allocated to, or attributed to each such proved Oil and Gas Interest is not materially less than the decimal fraction set forth in the Reserve Report, before and after payout, as the case may be, and described therein by the designations “net revenue interest,” “NRI,” or similar terms. Each well drilled in respect of proved producing Oil and Gas Interests described in the Reserve Report (1) is capable of, and is presently, either producing Hydrocarbons in commercially profitable quantities or in the process of being worked over or enhanced, and the Credit Party that owns such proved producing Oil and Gas Interests is currently receiving payments for its share of production, with no funds in respect of any thereof being presently held in suspense, other than any such funds being held in suspense pending delivery of appropriate division orders, and (2) has been drilled, bottomed, completed, and operated in compliance with all applicable laws, in the case of clauses (1) and (2), except where any failure to satisfy clause (1) or to comply with clause (2) would not have a Material Adverse Effect, and no such well which is currently producing Hydrocarbons is subject to any penalty in production by reason of such well having produced in excess of its allowable production.

EXCO CREDIT AGREEMENT – Page 60

Section 4.16. Insurance. The certificate signed by the Responsible Officer that attests to the existence and adequacy of, and summarizes, the property and casualty insurance program maintained by the Credit Parties that has been furnished by the Borrower to the Administrative Agent and the Lenders as of the Effective Date, is complete and accurate in all material respects as of the Effective Date and demonstrates the Borrower’s and the Restricted Subsidiaries’ compliance with Section 6.05.

Section 4.17. Solvency.

(a) Immediately after the consummation of the Transactions and immediately following the making of the initial Borrowing made on the Effective Date and after giving effect to the application of the proceeds thereof, (1) the fair value of the assets of the Credit Parties on a consolidated basis, at a fair valuation, will exceed the debts and liabilities, subordinated, contingent or otherwise, of the Credit Parties on a consolidated basis; (2) the present fair saleable value of the real and personal property of the Credit Parties on a consolidated basis will be greater than the amount that will be required to pay the probable liability of the Credit Parties on a consolidated basis on their debts and other liabilities, subordinated, contingent or otherwise, as such debts and other liabilities become absolute and matured; (3) the Credit Parties on a consolidated basis will be able to pay their debts and liabilities, subordinated, contingent or otherwise, as such debts and liabilities become absolute and matured; and (4) the Credit Parties on a consolidated basis will not have unreasonably small capital with which to conduct the businesses in which they are engaged as such businesses are now conducted and are proposed to be conducted after the date hereof.

(b) The Credit Parties do not intend to, and do not believe that they will, incur debts beyond their ability to pay such debts as they mature, taking into account the timing of and amounts of cash to be received by it and the timing of the amounts of cash to be payable on or in respect of its Indebtedness.

Section 4.18. Deposit Accounts. Except for the BG Escrow Account, the BG Operating Account and other deposit and investment accounts maintained at financial institutions other than the Administrative Agent or any Lender the aggregate balance of which does not exceed $250,000 at any time for all such other deposit and investment accounts taken as a whole, no Credit Party maintains any deposit or investment account into which either (a) proceeds of Hydrocarbon production from the Oil and Gas Interests included in the Borrowing Base Properties are deposited or (b) distributions and dividends on Equity Interests owned by any Credit Party are paid and deposited, in each case, other than (x) deposit or investment accounts maintained with the Administrative Agent or any other Lender or (y) deposit or investment accounts maintained with any other financial institutions acceptable to the Administrative Agent with respect to which a control agreement in favor of the Administrative Agent for the benefit of the Secured Parties, in form and substance reasonably satisfactory to the Administrative Agent, has been executed and delivered.

The Borrower will not, nor will it permit any of its Restricted Subsidiaries to, enter into or maintain any Swap Agreement, except the Existing Swap Agreements, and Swap Agreements entered into in the ordinary course of business with Approved Counterparties and not for speculative purposes to:

As used in this Section, “forecasted production from total proved reserves” means the forecasted production of Crude Oil and Natural Gas as reflected in the most recent Reserve Report delivered to the Administrative Agent pursuant to Section 6.01, after giving effect to any pro forma adjustments for the consummation of any acquisitions or dispositions since the effective date of such Reserve Report.

In the event any Credit Party enters into a Swap Agreement (including the Existing Swap Agreements), the terms and conditions of such Swap Agreement may not be amended or modified, nor may any Credit Party sell, assign, monetize, transfer, cancel or otherwise dispose of any of its rights and interests in any such Swap Agreement without the prior written consent of the Majority Lenders (it being understood that any Lender Counterparty may sell, assign, transfer, novate, or otherwise dispose of its rights and interests in any Swap Agreement to any Approved Counterparty at any time); provided that, notwithstanding the foregoing, any Credit

EXCO CREDIT AGREEMENT – Page 80

Party may enter into a Swap Modification so long as (i) within three (3) Business Days thereafter, the Borrower provides written notice to the Administrative Agent of the terms of such Swap Modification, setting forth in reasonable detail, (x) the effect of such Swap Modification on the aggregate notional volume of Crude Oil and Natural Gas subject to the Credit Parties’ Swap Agreements and (y) the amount of Net Cash Proceeds received by such Credit Party as a result of such Swap Modification, (ii) the aggregate notional volume of Crude Oil and Natural Gas affected by such Swap Modification, together with all other Swap Modifications consummated since the most recent Redetermination Date, does not exceed ten percent (10%) of the aggregate notional volume of Crude Oil and Natural Gas subject to the Credit Parties’ Swap Agreements in effect as of the most recent Redetermination Date, and (iii) the Borrower applies the Net Cash Proceeds received by any Credit Party as a result of such Swap Modification to prepay the Loans.

Each Credit Party and each Lender agrees and acknowledges that (i) the Existing Swap Agreements are Swap Agreements permitted under this Section 7.05, (ii) as of the Effective Date, the counterparty to each Existing Swap Agreement is a Lender Counterparty (or was a Lender Counterparty under and as defined in the Original Credit Agreements), (iii) the obligations of the Credit Parties under the Existing Swap Agreements are included in the defined term “Lender Hedging Obligations” and such obligations are entitled to the benefits of, and are secured by the Liens granted under, the Security Instruments and (iv) as of the Effective Date, the aggregate notional volume of Hydrocarbons under all Swap Agreements of the Credit Parties then in effect does not exceed the percentages of forecasted production from total proved reserves permitted pursuant to this Section 7.05 (calculated as if a Credit Party was entering into a new transaction under a Swap Agreement on the Effective Date).

Section 7.06. Restricted Payments. The Borrower will not, nor will it permit any of its Restricted Subsidiaries to, declare or make, or agree to pay or make, directly or indirectly, any Restricted Payment, except that (a) the Borrower may declare and make Restricted Payments with respect to its Equity Interests payable solely in its Equity Interests (other than Disqualified Stock), (b) the Borrower may make Restricted Payments pursuant to and in accordance with stock option plans or other benefit plans for management or employees of the Borrower and its Restricted Subsidiaries in an aggregate amount not to exceed $2,000,000 in any fiscal year, (c) any Restricted Subsidiary may make Restricted Payments to the Borrower or any Guarantor; provided that no Default has occurred and is continuing or would result from the making of such Restricted Payment, and (d) the Borrower may declare and pay cash dividends to the holders of its common stock; provided that on the date of and after giving effect to any such Restricted Payment, (i) no Default has occurred and is continuing, (ii) the aggregate amount of such cash dividends declared and paid in any period of four consecutive fiscal quarters shall not exceed $50,000,000, (iii) the Aggregate Commitment exceeds Aggregate Credit Exposure by an amount equal to or greater than ten percent (10%) of the Aggregate Commitment, and (iv) such Restricted Payment is permitted under the terms of the Indenture.

Section 7.07. Transactions with Affiliates. The Borrower will not, nor will it permit any of its Restricted Subsidiaries to, sell, lease or otherwise transfer any property or assets to, or purchase, lease or otherwise acquire any property or assets from, or otherwise engage in any other transactions with, any of its Affiliates, except (a) in the ordinary course of business at prices and on terms and conditions not less favorable to the Borrower or such Restricted

Article VIII

Guarantee of Obligations

Section 8.01. Guarantee of Payment. Each Guarantor unconditionally and irrevocably guarantees to the Administrative Agent for the benefit of the Secured Parties, the punctual payment of all Obligations now or which may in the future be owing by any Credit Party (the “Guaranteed Liabilities”). This Guarantee is a guaranty of payment and not of collection only. The Administrative Agent shall not be required to exhaust any right or remedy or take any action against the Borrower or any other Person or any collateral. The Guaranteed Liabilities include interest accruing after the commencement of a proceeding under bankruptcy, insolvency or similar laws of any jurisdiction at the rate or rates provided in the Loan Documents, or the Swap Agreements between any Credit Party and any Secured Party, as the case may be, regardless of whether such interest is an allowed claim. Each Guarantor agrees that, as between the Guarantor and the Administrative Agent, the Guaranteed Liabilities may be declared to be due and payable for the purposes of this Guarantee notwithstanding any stay, injunction or other prohibition which may prevent, delay or vitiate any declaration as regards the Borrower or any other Guarantor and that in the event of a declaration or attempted declaration, the Guaranteed Liabilities shall immediately become due and payable by each Guarantor for the purposes of this Guarantee.

Section 8.02. Guarantee Absolute. Each Guarantor guarantees that the Guaranteed Liabilities shall be paid strictly in accordance with the terms of this Agreement and the Swap Agreements to which any Secured Party is a party. The liability of each Guarantor hereunder is absolute and unconditional irrespective of: (a) any change in the time, manner or place of payment of, or in any other term of, all or any of the Loan Documents or the Guaranteed Liabilities, or any other amendment or waiver of or any consent to departure from any of the terms of any Loan Document or Guaranteed Liability, including any increase or decrease in the rate of interest thereon; (b) any release or amendment or waiver of, or consent to departure from, any other guaranty or support document, or any exchange, release or non-perfection of any collateral, for all or any of the Loan Documents or Guaranteed Liabilities; (c) any present or future law, regulation or order of any jurisdiction (whether of right or in fact) or of any agency thereof purporting to reduce, amend, restructure or otherwise affect any term of any Loan Document or Guaranteed Liability; (d) without being limited by the foregoing, any lack of validity or enforceability of any Loan Document or Guaranteed Liability; and (e) any other setoff, defense or counterclaim whatsoever (in any case, whether based on contract, tort or any other theory) with respect to the Loan Documents or the transactions contemplated thereby which might constitute a legal or equitable defense available to, or discharge of, the Borrower or a Guarantor.

Section 8.03. Guarantee Irrevocable. This Guarantee is a continuing guaranty of the payment of all Guaranteed Liabilities now or hereafter existing under this Agreement and such Swap Agreements to which any Secured Party is a party and shall remain in full force and effect until payment in full of all Guaranteed Liabilities and other amounts payable hereunder and until this Agreement and the Swap Agreements are no longer in effect or, if earlier, when the Guarantor has given the Administrative Agent written notice that this Guarantee has been revoked; provided that any notice under this Section shall not release the revoking Guarantor from any Guaranteed Liability, absolute or contingent, existing prior to the Administrative Agent’s actual receipt of the notice at its branches or departments responsible for this Agreement and such Swap Agreements and reasonable opportunity to act upon such notice.

EXCO CREDIT AGREEMENT – Page 84

Section 8.04. Reinstatement. This Guarantee shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Guaranteed Liabilities is rescinded or must otherwise be returned by any Secured Party on the insolvency, bankruptcy or reorganization of the Borrower, or any other Credit Party, or otherwise, all as though the payment had not been made.

Section 8.05. Subrogation. No Guarantor shall exercise any rights which it may acquire by way of subrogation, by any payment made under this Guarantee or otherwise, until all the Guaranteed Liabilities have been paid in full and this Agreement and the Swap Agreements to which any Lender Counterparty is a party are no longer in effect. If any amount is paid to the Guarantor on account of subrogation rights under this Guarantee at any time when all the Guaranteed Liabilities have not been paid in full, the amount shall be held in trust for the benefit of the Lenders and the Lender Counterparties and shall be promptly paid to the Administrative Agent to be credited and applied to the Guaranteed Liabilities, whether matured or unmatured or absolute or contingent, in accordance with the terms of this Agreement and such Swap Agreements. If any Guarantor makes payment to the Administrative Agent, Lenders, or any Lender Counterparties of all or any part of the Guaranteed Liabilities and all the Guaranteed Liabilities are paid in full and this Agreement and such Swap Agreements are no longer in effect, the Administrative Agent, Lenders and Lender Counterparties shall, at such Guarantor’s request, execute and deliver to such Guarantor appropriate documents, without recourse and without representation or warranty, necessary to evidence the transfer by subrogation to such Guarantor of an interest in the Guaranteed Liabilities resulting from the payment.

Section 8.06. Subordination. Without limiting the rights of the Administrative Agent, the Lenders and the Lender Counterparties under any other agreement, any liabilities owed by the Borrower to any Guarantor in connection with any extension of credit or financial accommodation by any Guarantor to or for the account of the Borrower, including but not limited to interest accruing at the agreed contract rate after the commencement of a bankruptcy or similar proceeding, are hereby subordinated to the Guaranteed Liabilities, and such liabilities of the Borrower to such Guarantor, if the Administrative Agent so requests, shall be collected, enforced and received by any Guarantor as trustee for the Administrative Agent and shall be paid over to the Administrative Agent on account of the Guaranteed Liabilities but without reducing or affecting in any manner the liability of the Guarantor under the other provisions of this Guarantee.

Section 8.07. Payments Generally. All payments by the Guarantors shall be made in the manner, at the place and in the currency (the “Payment Currency”) required by the Loan Documents and the Swap Agreement to which any Lender Counterparty is a party, as the case may be; provided, however, that (if the Payment Currency is other than Dollars) any Guarantor may, at its option (or, if for any reason whatsoever any Guarantor is unable to effect payments in the foregoing manner, such Guarantor shall be obligated to) pay to the Administrative Agent at its principal office the equivalent amount in Dollars computed at the selling rate of the Administrative Agent or a selling rate chosen by the Administrative Agent, most recently in effect on or prior to the date the Guaranteed Liability becomes due, for cable transfers of the Payment Currency to the place where the Guaranteed Liability is payable. In any case in which any Guarantor makes or is obligated to make payment in Dollars, the Guarantor shall hold the Administrative Agent, the Lenders and the Lender Counterparties harmless from any loss

EXCO CREDIT AGREEMENT – Page 85

incurred by the Administrative Agent, any Lender or any Lender Counterparty arising from any change in the value of Dollars in relation to the Payment Currency between the date the Guaranteed Liability becomes due and the date the Administrative Agent, such Lender or such Lender Counterparty is actually able, following the conversion of the Dollars paid by such Guarantor into the Payment Currency and remittance of such Payment Currency to the place where such Guaranteed Liability is payable, to apply such Payment Currency to such Guaranteed Liability.

Section 8.08. Setoff. Each Guarantor agrees that, in addition to (and without limitation of) any right of setoff, banker’s lien or counterclaim the Administrative Agent, any Lender or any Lender Counterparty may otherwise have, the Administrative Agent, such Lender or such Lender Counterparty shall be entitled, at its option, to offset balances (general or special, time or demand, provisional or final) held by it for the account of any Guarantor at any office of the Administrative Agent, such Lender or such Lender Counterparty, in Dollars or in any other currency, against any amount payable by such Guarantor under this Guarantee which is not paid when due (regardless of whether such balances are then due to such Guarantor), in which case it shall promptly notify such Guarantor thereof; provided that the failure of the Administrative Agent, such Lender, or such Lender Counterparty to give such notice shall not affect the validity thereof.

Section 8.09. Formalities. Each Guarantor waives presentment, notice of dishonor, protest, notice of acceptance of this Guarantee or incurrence of any Guaranteed Liability and any other formality with respect to any of the Guaranteed Liabilities or this Guarantee.

Section 8.10. Limitations on Guarantee. The provisions of the Guarantee under this Article VIII are severable, and in any action or proceeding involving any state corporate law, or any state, federal or foreign bankruptcy, insolvency, reorganization or other law affecting the rights of creditors generally, if the obligations of any Guarantor under this Guarantee would otherwise be held or determined to be avoidable, invalid or unenforceable on account of the amount of such Guarantor’s liability under this Guarantee, then, notwithstanding any other provision of this Guarantee to the contrary, the amount of such liability shall, without any further action by the Guarantors, the Administrative Agent, any Lender or any Lender Counterparty, be automatically limited and reduced to the highest amount that is valid and enforceable as determined in such action or proceeding (such highest amount determined hereunder being the relevant Guarantor’s “Maximum Liability”). This Section 8.10, with respect to the Maximum Liability of the Guarantors, is intended solely to preserve the rights of the Administrative Agent, Lenders and Lender Counterparties hereunder to the maximum extent not subject to avoidance under applicable law, and no Guarantor nor any other Person shall have any right or claim under this Section 8.10 with respect to the Maximum Liability, except to the extent necessary so that none of the obligations of any Guarantor hereunder shall be rendered voidable under applicable law.

Article IX

Article X

The Administrative Agent

Each of the Lenders and the Issuing Bank hereby irrevocably appoints the Administrative Agent as its agent and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof, together with such actions and powers as are reasonably incidental thereto.

The bank serving as the Administrative Agent hereunder shall have the same rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Administrative Agent, and such bank and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with any Credit Party or other Affiliate thereof as if it were not the Administrative Agent hereunder.

The Administrative Agent shall not have any duties or obligations except those expressly set forth herein. Without limiting the generality of the foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing, (b) the Administrative Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby that the Administrative Agent is required to exercise in writing as directed by the Majority Lenders or the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 11.02), and (c) except as expressly set forth herein, the Administrative Agent shall not have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to any Credit Party that is communicated to or obtained by the bank serving as Administrative Agent or any of its Affiliates in any capacity. The Administrative Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Majority Lenders or the Required Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 11.02) or in the absence of its own gross negligence or willful misconduct. The Administrative Agent shall be deemed not to have knowledge of any Default unless and until written notice thereof is given to the Administrative Agent by the Borrower or a Lender, and the Administrative Agent shall not be responsible for or have any

EXCO CREDIT AGREEMENT – Page 89

duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement, (ii) the contents of any certificate, report or other document delivered hereunder or in connection herewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement or any other agreement, instrument or document, or (v) the satisfaction of any condition set forth in Article V or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent. No Person identified as a Co-Syndication Agent, Co-Documentation Agent or Co-Lead Arranger, in each case in its respective capacity as such, shall have any responsibilities or duties, or incur any liability, under this Agreement or the other Loan Documents.

The Administrative Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed or sent by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or by telephone and believed by it to be made by the proper Person, and shall not incur any liability for relying thereon. The Administrative Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

The Administrative Agent may perform any and all its duties and exercise its rights and powers by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers through their respective Related Parties. The exculpatory provisions of the preceding paragraphs shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent.

Subject to the appointment and acceptance of a successor Administrative Agent as provided in this paragraph, the Administrative Agent may resign at any time by notifying the Lenders, the Issuing Bank and the Borrower. Upon any such resignation, the Majority Lenders shall have the right, in consultation with the Borrower, to appoint a successor. If no successor shall have been so appointed by the Majority Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may, on behalf of the Lenders and the Issuing Bank, appoint a successor Administrative Agent which shall be a bank with an office in Chicago, Illinois or New York, New York, or an Affiliate of any such bank. Upon the acceptance of its appointment as Administrative Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder. The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the Administrative Agent’s resignation hereunder, the provisions of this Article and Section 11.03 shall continue in effect for the benefit of such retiring Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as Administrative Agent.

EXCO CREDIT AGREEMENT – Page 90

Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any related agreement or any document furnished hereunder or thereunder.

Each Lender and the Issuing Bank hereby authorizes the Administrative Agent to release any Collateral that it is permitted to be sold or released pursuant to the terms of the Loan Documents. Each Lender and the Issuing Bank hereby authorizes the Administrative Agent to execute and deliver to the Borrower, at the Borrower’s sole cost and expense, any and all releases of Liens, termination statements, assignments or other documents reasonably requested by the Borrower in connection with any sale or other disposition of Collateral to the extent such sale or other disposition is permitted by the terms of Section 7.03 or is otherwise authorized by the terms of the Loan Documents.

Section 11.02. Waivers; Amendments.

(a) No failure or delay by the Administrative Agent, the Issuing Bank or any Lender in exercising any right or power hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power.

(vi) change Section 2.19(b), Section 2.19(c) or Section 2.19(e) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender;

Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby (including any Affiliate of the Issuing Bank that issues any Letter of Credit), Participants (to the extent provided in paragraph (c) of this Section) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent, the Issuing Bank and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b)

(i) Subject to the conditions set forth in paragraph (b)(ii) below, any Lender may assign to one or more assignees all or a portion of its rights and obligations under

EXCO CREDIT AGREEMENT – Page 95

this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it) with the prior written consent (such consent not to be unreasonably withheld) of:

(A) the Borrower, provided that no consent of the Borrower shall be required for an assignment to a Lender, an Affiliate of a Lender, a Federal Reserve Bank, an Approved Fund or, if an Event of Default has occurred and is continuing, any other assignee;

(B) the Administrative Agent; and

(ii) Assignments shall be subject to the following additional conditions:

(A) except in the case of an assignment to a Lender, an Affiliate of a Lender, an Approved Fund or an assignment of the entire remaining amount of the assigning Lender’s Commitment or Loans, the amount of the Commitment or Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent) shall not be less than $5,000,000, unless each of the Borrower and the Administrative Agent otherwise consent, provided that no such consent of the Borrower shall be required if an Event of Default has occurred and is continuing;

(B) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations in respect of such Lender’s Commitment and such Lender’s Loans under this Agreement;

(C) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500; and

(D) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire.

EXCO CREDIT AGREEMENT – Page 96

interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Section 2.16, Section 2.17, Section 2.18 and Section 11.03). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 11.04 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (c) of this Section except that any attempted assignment or transfer by any Lender that does not comply with clause (C) of Section 11.04(b)(ii) shall be null and void.

(iv) The Administrative Agent, acting for this purpose as an agent of the Borrower, shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitment and Applicable Percentage of, and principal amount of the Loans and LC Disbursements owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Credit Parties, the Administrative Agent, the Issuing Bank and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Credit Parties, the Issuing Bank and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(v) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in paragraph (b) of this Section any written consent to such assignment required by paragraph (b) of this Section, the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the Register; provided that if either the assigning Lender or the assignee shall have failed to make any payment required to be made by it pursuant to Section 2.07(d) or Section 2.07(e), Section 2.08, Section 2.19(d) or Section 11.03(c), the Administrative Agent shall have no obligation to accept such Assignment and Assumption and record the information therein in the Register unless and until such payment shall have been made in full, together with all accrued interest thereon. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this paragraph.

(c)

(i) Any Lender may, without the consent of the Borrower, the Administrative Agent or the Issuing Bank, sell participations to one or more banks or other entities (a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans owing to it);

EXCO CREDIT AGREEMENT – Page 97

provided that (A) such Lender’s obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (C) the Borrower, the Administrative Agent, the Issuing Bank and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 11.02(b) that affects such Participant. Subject to paragraph (c)(ii) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Section 2.16, Section 2.17 and Section 2.18 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 11.08 as though it were a Lender, provided such Participant agrees to be subject to Section 2.19(c) as though it were a Lender.

(ii) A Participant shall not be entitled to receive any greater payment under Section 2.16 or Section 2.18 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the prior written consent of the Borrower. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 2.18 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 2.18(e) as though it were a Lender.

(d) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including without limitation any pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section shall not apply to any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

Section 11.05. Survival. All covenants, agreements, representations and warranties made by the Credit Parties herein and in the certificates or other instruments delivered in connection with or pursuant to this Agreement shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the making of any Loans and issuance of any Letters of Credit, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent, the Issuing Bank or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Aggregate Commitment has not expired or terminated. The provisions of Section 2.16, Section 2.17, Section 2.18 and Section 11.03 and Article X shall survive and remain in full force and effect regardless of the consummation of the transactions

EXCO CREDIT AGREEMENT – Page 98

contemplated hereby, the repayment of the Loans, the expiration or termination of the Letters of Credit and the Aggregate Commitment or the termination of this Agreement or any provision hereof.

Section 11.06. Counterparts; Integration; Effectiveness. This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement and any separate letter agreements with respect to fees payable to the Administrative Agent and J.P. Morgan constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT AMONG THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES. Except as provided in Section 5.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement by telecopy or other electronic means shall be effective as delivery of a manually executed counterpart of this Agreement.

Section 11.07. Severability. Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

Section 11.08. Right of Setoff. If an Event of Default shall have occurred and be continuing, each Lender and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other obligations at any time owing by such Lender or Affiliate to or for the credit or the account of the Borrower against any of and all the obligations of any Credit Party now or hereafter existing under this Agreement held by such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement and although such obligations may be unmatured. The rights of each Lender under this Section and Section 8.08 are in addition to other rights and remedies (including other rights of setoff) which such Lender may have.

Section 11.09. GOVERNING LAW; JURISDICTION; CONSENT TO SERVICE OF PROCESS.

(d) EACH PARTY TO THIS AGREEMENT IRREVOCABLY CONSENTS TO SERVICE OF PROCESS IN THE MANNER PROVIDED FOR NOTICES IN SECTION 11.01. NOTHING IN THIS AGREEMENT WILL AFFECT THE RIGHT OF ANY PARTY TO THIS AGREEMENT TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW.

Section 11.12. Confidentiality. Each of the Administrative Agent, the Issuing Bank and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ directors, officers, employees and agents, including accountants, legal counsel and other advisors (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by any regulatory authority or any self-regulatory authority or agency possessing investigative powers and the ability to sanction members for non-compliance, (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party to this Agreement, (e) in connection with the exercise of any remedies hereunder or any suit, action or proceeding relating to this Agreement or the enforcement of rights hereunder, (f) subject to an agreement containing provisions substantially the same as, or otherwise consistent with, those of this Section, to (i) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement or (ii) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to the Credit Parties and their obligations, (g) with the consent of the Borrower or (h) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section or (ii) becomes available to the Administrative Agent, the Issuing Bank or any Lender on a nonconfidential basis from a source other than a Credit Party. For the purposes of this Section, “Information” means all information received from any Credit Party relating to any Credit Party or its business, other than any such information that is available to the Administrative Agent, the Issuing Bank or any Lender on a nonconfidential basis prior to disclosure by any Credit Party; provided that, in the case of information received from any Credit Party after the date hereof, such information is clearly identified at the time of delivery as confidential. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information.

Section 11.13. Interest Rate Limitation. Notwithstanding anything herein to the contrary, if at any time the interest rate applicable to any Loan, together with all fees, charges and other amounts which are treated as interest on such Loan under applicable law (collectively the “Charges”), shall exceed the maximum lawful rate (the “Maximum Rate”) which may be contracted for, charged, taken, received or reserved by the Lender holding such Loan in accordance with applicable law, the rate of interest payable in respect of such Loan hereunder, together with all Charges payable in respect thereof, shall be limited to the Maximum Rate and, to the extent lawful, the interest and Charges that would have been payable in respect of such Loan but were not payable as a result of the operation of this Section shall be cumulated and the interest and Charges payable to such Lender in respect of other Loans or periods shall be increased (but not above the Maximum Rate therefor) until such cumulated amount, together with interest thereon at the Federal Funds Effective Rate to the date of repayment, shall have been received by such Lender. Chapter 346 of the Texas Finance Code (which regulates certain revolving credit accounts (formerly Tex. Rev. Civ. Stat. Ann. Art. 5069, Ch. 15)) shall not apply to this Agreement or to any Loan, nor shall this Agreement or any Loan be governed by or be subject to the provisions of such Chapter 346 in any manner whatsoever.

EXCO CREDIT AGREEMENT – Page 101

Section 11.14. USA PATRIOT Act. Each Lender that is subject to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”) hereby notifies each Credit Party that pursuant to the requirements of the Act, it is required to obtain, verify and record information that identifies each Credit Party, which information includes the name and address of each Credit Party and other information that will allow such Lender to identify each Credit Party in accordance with the Act. The Borrower shall, upon the request of the Administrative Agent or any Lender, provide all documentation and other information that the Administrative Agent or such Lender reasonably requires to comply with its ongoing obligations under applicable “know your customer” and anti-money laundering rules and regulations, including the Act.

Section 11.15. Original Credit Agreements. Upon the Effective Date, this Agreement shall supersede and replace in their respective entireties the Original Credit Agreements; provided, however, that (a) all loans, letters of credit, and other indebtedness, obligations and liabilities outstanding under the Original Credit Agreements on such date shall continue to constitute Loans, Letters of Credit and other indebtedness, obligations and liabilities under this Agreement, (b) the execution and delivery of this Agreement or any of the Loan Documents hereunder shall not constitute a novation, refinancing or any other fundamental change in the relationship among the parties and (c) the Loans, Letters of Credit, and other indebtedness, obligations and liabilities outstanding hereunder, to the extent outstanding under the Original Credit Agreements immediately prior to the date hereof, shall constitute the same loans, letters of credit, and other indebtedness, obligations and liabilities as were outstanding under the Original Credit Agreements.

Section 11.16. Reaffirmation and Grant of Security Interest. Each Credit Party hereby (i) confirms that each Security Instrument (as defined in the Original Credit Agreements) to which it is a party or is otherwise bound and all Collateral encumbered thereby, will continue to guarantee or secure, as the case may be, to the fullest extent possible in accordance with the Loan Documents, and regardless of whether any Guarantor under this Agreement was a “Borrower” under either of the Original Credit Agreements, the payment and performance of all Obligations and Guaranteed Liabilities under this Agreement and the Secured Indebtedness (as such term is defined in the Mortgages) under the Mortgages, as the case may be, and (ii) reaffirms its grant to the Administrative Agent for the benefit of the Secured Parties of a continuing Lien on and security interest in and to such Credit Party’s right, title and interest in, to and under all Collateral as collateral security for the prompt payment and performance in full when due of the Obligations and Guaranteed Liabilities under this Agreement and the Secured Indebtedness under the Mortgages (whether at stated maturity, by acceleration or otherwise) in accordance with the terms thereof.

Section 11.17. Reallocation of Commitments and Loans. The Lenders have agreed among themselves to reallocate their respective Commitments as contemplated by this Agreement and to adjust their interests in the Aggregate Commitment and the Loans accordingly. On the Effective Date and after giving effect to such reallocation and adjustment of the Aggregate Commitment, the Commitment and Applicable Percentage of each Lender shall be as

EXCO CREDIT AGREEMENT – Page 102

set forth on Schedule 2.01 and each Lender shall own its Applicable Percentage of the outstanding Loans. The reallocation and adjustment to the Commitments of each Lender as contemplated by this Section 11.17 shall be deemed to have been consummated pursuant to the terms of the Assignment and Assumption attached as Exhibit A hereto as if each of the Lenders had executed an Assignment and Assumption with respect to such reallocation and adjustment. The Borrower and Administrative Agent hereby consent to such reallocation and adjustment of the Commitments. The Administrative Agent hereby waives the $3,500 processing and recordation fee set forth in Section 11.04(b)(ii)(C) with respect to the assignments and reallocations of the Commitments contemplated by this Section 11.17. To the extent requested by any Lender, and in accordance with Section 2.17, the Borrower shall pay to such Lender, within the time period prescribed by Section 2.17, any amounts required to be paid by the Borrower under Section 2.17 in the event the payment of any principal of any Eurodollar Loan or the conversion of any Eurodollar Loan other than on the last day of an Interest Period applicable thereto is required in connection with the reallocation contemplated by this Section 11.17.
