ARTICLE II

THE CREDITS

Section 2.01 Commitments. Subject to the terms and conditions set forth herein, each Lender agrees to make revolving loans (“Revolving Loans”) to the Borrower during the Availability Period in an aggregate principal amount that will not result in (a) such Lender’s Revolving Credit Exposure exceeding its Applicable Percentage of the Loan Limit or (b) the total Revolving Credit Exposures exceeding the Loan Limit. Within the foregoing limits and subject to the terms and conditions set forth herein, the Borrower may borrow, repay and reborrow the Loans.

Section 2.02 Loans and Borrowings.

(a) Borrowings; Several Obligations. 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 are several and no Lender shall be responsible for any other Lender’s failure to make Loans as required.

(b) Types of Loans. Subject to Section 3.03, each Borrowing (other than Borrowings of Swingline Loans) 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) Minimum Amounts; Limitation on Number of Borrowings. 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 $5,000,000. At the time that each ABR Borrowing is made, such Borrowing shall be in an aggregate amount that is an integral multiple of $500,000 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 total Commitments or that is required to finance the reimbursement of an LC Disbursement as contemplated by Section 2.08(c). 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 ten (10) Eurodollar Borrowings outstanding. Notwithstanding any other provision of this Agreement, the Borrower shall not be entitled to request, or to elect to convert or continue, any Borrowing if the Interest Period requested with respect thereto would end after the Maturity Date.

(d) Notes. The Revolving Loans made by each Lender shall be evidenced by a single promissory note of the Borrower in substantially the form of Exhibit A-1, dated, in the case of (i) any Lender party hereto as of the date of this Agreement, as of the date of this Agreement, or (ii) any Lender that becomes a party hereto pursuant to an Assignment and Assumption, as of the effective date of the Assignment and Assumption, payable to such Lender and otherwise duly completed. The Swingline Loans made by the Swingline Lender shall be evidenced by a single promissory note of the Borrower in substantially the form of Exhibit A-2, dated as of the date of this Agreement. The date, amount, Type, interest rate and, if applicable,

Interest Period of each Loan made by each Lender, and all payments made on account of the principal thereof, shall be recorded by such Lender on its books for its Note. Failure to make any such recordation shall not affect any Lender’s or the Borrower’s rights or obligations in respect of such Loans or affect the validity of such transfer by any Lender of its Note.

Section 2.03 Requests for Borrowings. To request a Borrowing of Revolving Loans, the Borrower shall notify the Administrative Agent of such request by telephone (a) in the case of a Eurodollar Borrowing, not later than 1:00 p.m., New York City time, three Business Days before the date of the proposed Borrowing or (b) in the case of an ABR Borrowing, not later than 12:00 p.m., New York City time, on the same Business Day of the proposed Borrowing; provided that no such notice shall be required for any deemed request of an ABR Borrowing to finance the reimbursement of an LC Disbursement as provided in Section 2.08(c) or any deemed request of an ABR Borrowing to repay any Swingline Loan as provided in Section 2.09(c). Each such telephonic Borrowing Request shall be irrevocable and shall be confirmed promptly by hand delivery, email or fax to the Administrative Agent of a written Borrowing Request in substantially the form of Exhibit B and signed by the Borrower. Each such telephonic and written Borrowing Request shall specify the following information in compliance with Section 2.02:

(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;

(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”;

(v) the amount of the then effective Borrowing Base, the amount of the then effective Aggregate Commitment, the current total Revolving Credit Exposures (without regard to the requested Borrowing) and the pro forma total Revolving Credit Exposures (giving effect to the requested Borrowing); and

(vi) the location and number of the Borrower’s account to which funds are to be disbursed, which shall comply with the requirements of Section 2.05.

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 month’s duration. Each Borrowing Request shall constitute a representation by the Borrower that the amount of the requested Borrowing shall not cause the total Revolving Credit Exposures to exceed the Loan Limit.

Promptly following receipt of a Borrowing Request in accordance with this Section 2.03, 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 2.04 Interest Elections.

(a) Conversion and Continuance. Each Borrowing (other than Borrowings of Swingline Loans) 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. 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 2.04. 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) Interest Election Requests. To make an election pursuant to this Section 2.04, the Borrower shall notify the Administrative Agent of such election by telephone by the time that a Borrowing Request would be required under Section 2.03 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, email or fax to the Administrative Agent of a written Interest Election Request in substantially the form of Exhibit C and signed by the Borrower.

(c) Information in Interest Election Requests. Each telephonic and written Interest Election Request shall specify the following information in compliance with Section 2.02

(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 Section 2.04(c)(iii) and (iv) 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”.

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 month’s duration.

(d) Notice to Lenders by the Administrative Agent. 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) Effect of Failure to Deliver Timely Interest Election Request and Events of Default and Borrowing Base Deficiencies on Interest Election. 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 or a Borrowing Base Deficiency has occurred and is continuing: (i) no outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing (and 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) unless repaid, each Eurodollar Borrowing shall be converted to an ABR Borrowing at the end of the Interest Period applicable thereto.

Section 2.05 Funding of Borrowings.

(a) Funding by Lenders. Not later than 1:00 p.m., New York City time, on the date specified in the applicable Borrowing Request, each Lender shall make each Revolving Loan to be made by it hereunder by wire transfer of immediately available funds 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 maintained with the Administrative Agent and designated by the Borrower in the applicable Borrowing Request; provided that (A) ABR Loans made to finance the reimbursement of an LC Disbursement as provided in Section 2.08(c) shall be remitted by the Administrative Agent to the Issuing Bank and (B) Loans to be made for the purpose of refinancing Swingline Loans shall be made by the Lenders as provided in Section 2.09(c). Nothing herein shall be deemed to obligate any Lender to obtain the funds for its Loan in any particular place or manner or to constitute a representation by any Lender that it has obtained or will obtain the funds for its Loan in any particular place or manner.

(b) Presumption of Funding by the Lenders. 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 Section 2.05(a) 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 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 for the respective Loan. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender’s Loan included in such Borrowing. Nothing in this Section 2.05 shall be deemed to relieve any Lender from its obligation to fulfill its commitments hereunder or to prejudice any rights that the Borrower may have against any Lender as a result of any breach by such Lender of its obligations hereunder (it being understood, however, that no Agent or Lender shall be responsible for the failure of any other Lender to fulfill its commitments hereunder).

Section 2.06 Termination and Reduction of Commitments and Maximum Aggregate Amount.

(a) Scheduled Termination of Commitments. Unless previously terminated, the Aggregate Commitment shall terminate on the Maturity Date. If at any time the Maximum Aggregate Amount or the Borrowing Base is terminated (except due to an Investment Grade Period) or reduced to zero, then the Aggregate Commitment shall terminate on the effective date of such termination or reduction.

(b) Optional Termination and Reduction of Maximum Aggregate Amount or Aggregate Commitment.

(i) The Borrower may at any time terminate, or from time to time reduce, the Maximum Aggregate Amount or Aggregate Commitment; provided that (A) upon any reduction of the Maximum Aggregate Amount to an amount less than the Aggregate Commitment, the Aggregate Commitment shall automatically be reduced (ratably in accordance with each Lender’s Applicable Percentage) so that the Aggregate Commitment equals the Maximum Aggregate Amount (as so reduced), (B) each reduction shall be in an amount that is an integral multiple of $1,000,000 and not less than $5,000,000 and (C) the Borrower shall not terminate or reduce the Maximum Aggregate Amount or the Aggregate Commitment if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 3.04(c), the total Revolving Credit Exposures would exceed the Loan Limit.

(ii) The Borrower shall notify the Administrative Agent of any election to terminate or reduce the Maximum Aggregate Amount or Aggregate Commitment under Section 2.06(b)(i) 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 2.06(b)(ii) shall be irrevocable; provided that a notice of termination of the Maximum Aggregate Amount or 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 or reduction of the Maximum Aggregate Amount or Aggregate Commitment shall be permanent and may not be reinstated. Each reduction of the Maximum Aggregate Amount or Aggregate Commitment shall be made ratably among the Lenders in accordance with each Lender’s Applicable Percentage.

(iii) Upon any redetermination or other adjustment in the Borrowing Base pursuant to this Agreement that would otherwise result in the Borrowing Base becoming less than the Aggregate Commitment, the Aggregate Commitment shall be automatically reduced (ratably among the Lenders in accordance with each Lender’s

Applicable Percentage) so that it equals such redetermined Borrowing Base (and Annex I shall be deemed amended to reflect such amendments to each Lender’s Commitment and the Aggregate Commitment).

Section 2.07 Borrowing Base.

(a) Initial Borrowing Base. For the period from and including the Effective Date to but excluding the first Redetermination Date, the amount of the Borrowing Base shall be $2,100,000,000. Notwithstanding the foregoing, the Borrowing Base may be subject to further adjustments in between Scheduled Redeterminations from time to time pursuant to this Section 2.07 or Section 8.12(c).

(b) Scheduled and Interim Redeterminations. The Borrowing Base shall be redetermined semi-annually in accordance with this Section 2.07 (a “Scheduled Redetermination”), and, subject to Section 2.07(d), such redetermined Borrowing Base shall become effective and applicable to the Borrower, the Agents, the Issuing Bank and the Lenders on April 1st and October 1st of each year (or, in each case, such date promptly thereafter as reasonably practicable), commencing April 1, 2015. In addition, the Borrower may, by notifying the Administrative Agent thereof, and the Administrative Agent may, at the direction of the Required Lenders, by notifying the Borrower thereof, one time between Scheduled Redeterminations, each elect to cause the Borrowing Base to be redetermined between Scheduled Redeterminations (an “Interim Redetermination”) in accordance with this Section 2.07. In addition to, and not including and/or limited by the Interim Redetermination rights above, the Borrower may, by notifying the Administrative Agent thereof, at any time between Scheduled Redeterminations, request additional Interim Redeterminations of the Borrowing Base pursuant to Section 2.07(g) below in connection with acquisitions of Oil and Gas Properties described therein.

(i) Each Scheduled Redetermination and each Interim Redetermination shall be effectuated as follows: upon receipt by the Administrative Agent of (A) the Reserve Report and the certificate required to be delivered by the Borrower to the Administrative Agent, in the case of a Scheduled Redetermination, pursuant to Section 8.11(a) and (c), and, in the case of an Interim Redetermination, pursuant to Section 8.11(b) and (c), and (B) such other reports, data and supplemental information, including the information provided pursuant to Section 8.11(c), as may, from time to time, be reasonably requested by the Required Lenders (the Reserve Report, such certificate and such other reports, data and supplemental information being the “Engineering Reports”), the Administrative Agent shall evaluate the information contained in the Engineering Reports and shall in good faith in its sole discretion propose a new Borrowing Base (the “Proposed Borrowing Base”) based upon such information and such other information (including the status of title information with respect to the Oil and Gas Properties as described in the Engineering Reports and the existence of any Swap Agreements or any other Debt) as the Administrative Agent deems appropriate in accordance with its usual and customary oil and gas lending criteria as it exists at the particular time;

(ii) The Administrative Agent shall notify the Borrower and the Lenders of the Proposed Borrowing Base (the “Proposed Borrowing Base Notice”) promptly after the Administrative Agent has received complete Engineering Reports from the Borrower and has had a reasonable opportunity to determine the Proposed Borrowing Base in accordance with Section 2.07(c)(i); and

(iii) Any Proposed Borrowing Base that would increase the Borrowing Base then in effect must be approved by the Borrowing Base Increase Lenders (in each such Lender’s good faith in its sole discretion in accordance with such Lender’s usual and customary oil and gas lending criteria as it exists at the particular time) as provided in this Section 2.07(c)(iii); and any Proposed Borrowing Base that would decrease or maintain the Borrowing Base then in effect must be approved or be deemed to have been approved by the Required Lenders (in each such Lender’s good faith in its sole discretion in accordance with such Lender’s usual and customary oil and gas lending criteria as it exists at the particular time) as provided in this Section 2.07(c)(iii). Upon receipt of the Proposed Borrowing Base Notice, each Lender shall have fifteen (15) days to agree with the Proposed Borrowing Base or disagree with the Proposed Borrowing Base by proposing an alternate Borrowing Base. If, in the case of any Proposed Borrowing Base that would decrease or maintain the Borrowing Base then in effect, at the end of such fifteen (15) days, any Lender has not communicated its approval or disapproval in writing to the Administrative Agent, such silence shall be deemed to be an approval of the Proposed Borrowing Base. If, in the case of any Proposed Borrowing Base that would increase the Borrowing Base then in effect, at the end of such fifteen (15) days, any Lender has not communicated its approval or disapproval in writing to the Administrative Agent, such silence shall be deemed to be a disapproval of the Proposed Borrowing Base. If, at the end of such 15-day period, the Borrowing Base Increase Lenders, in the case of a Proposed Borrowing Base that would increase the Borrowing Base then in effect, or the Required Lenders, in the case of a Proposed Borrowing Base that would decrease or maintain the Borrowing Base then in effect, have approved or, in the case of a decrease or reaffirmation, deemed to have approved, as aforesaid, then the Proposed Borrowing Base shall become the new Borrowing Base, effective on the date specified in Section 2.07(d). If, however, at the end of such 15-day period, the Borrowing Base Increase Lenders or the Required Lenders, as applicable, have not approved or, in the case of a decrease or reaffirmation, deemed to have approved, as aforesaid, then the Administrative Agent shall promptly thereafter poll the Lenders to ascertain the highest Borrowing Base then acceptable to (x) in the case of a decrease or reaffirmation, a number of Lenders sufficient to constitute the Required Lenders and (y) in the case of an increase, the Borrowing Base Increase Lenders, and such amount shall become the new Borrowing Base, effective on the date specified in Section 2.07(d).

(d) Effectiveness of a Redetermined Borrowing Base. After a redetermined Borrowing Base is approved or is deemed to have been approved by the Borrowing Base Increase Lenders or the Required Lenders, as applicable, pursuant to Section 2.07(c)(iii), the Administrative Agent shall promptly thereafter notify the Borrower and the Lenders of the amount of the redetermined Borrowing Base (the “New Borrowing Base Notice”), and such amount shall become the new Borrowing Base, effective and applicable to the Borrower, the Administrative Agent, the Issuing Bank and the Lenders:

(i) in the case of a Scheduled Redetermination, (A) if the Administrative Agent shall have received the Engineering Reports required to be delivered by the Borrower pursuant to Section 8.11(a) and (c) in a timely and complete manner, then on the April 1st or October 1st (or, in each case, such date promptly thereafter as reasonably practicable), as applicable, following such New Borrowing Base Notice, or (B) if the Administrative Agent shall not have received the Engineering Reports required to be delivered by the Borrower pursuant to Section 8.11(a) and (c) in a timely and complete manner, then on the Business Day next succeeding delivery of such New Borrowing Base Notice; and

(ii) in the case of an Interim Redetermination, on the Business Day next succeeding delivery of such New Borrowing Base Notice.

Such amount shall then become the Borrowing Base until the next Scheduled Redetermination Date, the next Interim Redetermination Date or the next adjustment to the Borrowing Base under Section 2.07(e), Section 2.07(f), Section 2.07(g) or Section 8.12(c), whichever occurs first. Notwithstanding the foregoing, no Scheduled Redetermination or Interim Redetermination shall become effective until the New Borrowing Base Notice related thereto is received by the Borrower.

(e) Reduction Upon Issuance of Senior Notes. If the Borrower issues any Senior Notes during the period between Scheduled Redetermination dates, then (i) on the date on which such Senior Notes are issued, the Borrowing Base then in effect shall be reduced by an amount equal to the product of 0.25 multiplied by the stated principal amount of such Senior Notes, and (ii) the Borrowing Base as so reduced shall become the new Borrowing Base immediately upon the date of such issuance, effective and applicable to the Borrower, the Administrative Agent, the Swingline Lender, the Issuing Bank and the Lenders on such date until the next redetermination or modification thereof hereunder. For purposes of this Section 2.07(e), if any such Debt is issued at a discount or otherwise sold for less than “par”, the reduction shall be calculated based upon the stated principal amount without reference to such discount. Notwithstanding the foregoing, no such reduction to the Borrowing Base shall be required with respect to (x) Senior Notes issued to refinance the Existing Senior Notes up to the principal amount of the Existing Senior Notes (and for the avoidance of doubt, any principal amounts issued in excess thereof shall be subject to the foregoing reduction) or (y) Senior Notes in an aggregate stated principal amount not to exceed $300,000,000 issued by the Borrower prior to April 1, 2015 (and for the avoidance of doubt, any principal amounts issued in excess thereof shall be subject to the foregoing reduction).

(f) Reduction Upon Asset Sales and Swap Liquidations. If, during the period between Scheduled Redetermination dates, there are (i) sales or other dispositions of Borrowing Base Properties or any interest therein (including as a result of any Casualty Events), (ii) sales or dispositions of any Restricted Subsidiary owning Borrowing Base Properties and/or (iii) the Liquidation of any Swap Agreements in respect of commodities, then in each case, the Borrowing Base shall be reduced if required by Section 9.12(d)(iv), in the manner set forth therein.

(g) Acquisition Redetermination. In connection with any acquisition (or series of acquisitions during the period between Scheduled Redetermination dates) of Oil and Gas Properties by the Credit Parties with a purchase price exceeding 5% of the Borrowing Base then in effect, the Borrower may, upon written notice to the Administrative Agent, elect to cause the Borrowing Base to be redetermined in accordance with the procedures set forth for Interim Redeterminations, to be effective on or about the closing of such acquisition.

(h) Administrative Agent Data. The Administrative Agent hereby agrees to provide promptly, and in any event within 3 Business Days, following its receipt of a request by the Borrower, an updated Bank Price Deck. In addition, the Administrative Agent and the Lenders agree, upon request, to meet with the Borrower to discuss their evaluation of the reservoir engineering of the Oil and Gas Properties included in the Reserve Report and their respective methodologies for valuing such properties and the other factors considered in calculating the Borrowing Base.

(i) Investment Grade Period. Notwithstanding anything in this Agreement to the contrary, during any Investment Grade Period, the provisions of clauses (a) through (g) of this Section 2.07, Section 8.12(c) and Section 9.12(d)(iv) and any other provisions tied to the Borrowing Base and/or a Borrowing Base Deficiency will be deemed to be inapplicable and shall be disregarded for all purposes. Upon the end of any Investment Grade Period, (i) the Borrowing Base will be, until so redetermined pursuant to clause (ii), the most recent Borrowing Base that was in effect prior to such Investment Grade Period and (ii) the Borrower will provide to the Administrative Agent a Reserve Report of the type described in Section 8.11(b) no later than thirty (30) days following the end of such Investment Grade Period, and the Borrowing Base will be redetermined using the procedures for Interim Redeterminations set forth above.

Section 2.08 Letters of Credit.

(a) General. Subject to the terms and conditions set forth herein, the Borrower may request the issuance of dollar denominated Letters of Credit for its own account or for the account of any of its Restricted Subsidiaries, 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; provided that the Borrower may not request the issuance, amendment, renewal or extension of a Letter of Credit hereunder if a Borrowing Base Deficiency exists at such time or would exist as a result of the issuance of such Letter of Credit. 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, email or fax (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 (not less than three (3) Business Days in advance of the requested date of issuance, amendment, renewal or extension) a notice:

(i) requesting the issuance of a Letter of Credit or identifying the Letter of Credit to be amended, renewed or extended;

(ii) specifying the date of issuance, amendment, renewal or extension (which shall be a Business Day);

(iii) specifying the date on which such Letter of Credit is to expire (which shall comply with Section 2.08(c));

(iv) specifying the amount of such Letter of Credit;

(v) specifying 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; and

(vi) specifying the amount of the then effective Borrowing Base and whether a Borrowing Base Deficiency exists at such time, the current total Revolving Credit Exposures (without regard to the requested Letter of Credit or the requested amendment, renewal or extension of an outstanding Letter of Credit) and the pro forma total Revolving Credit Exposures (giving effect to the requested Letter of Credit or the requested amendment, renewal or extension of an outstanding Letter of Credit).

Each notice shall constitute a representation and warranty by the Borrower that after giving effect to the requested issuance, amendment, renewal or extension, as applicable, (x) the LC Exposure shall not exceed the LC Commitment and (y) the total Revolving Credit Exposures shall not exceed the Loan Limit.

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; provided that, in the event of any conflict between such application or any Letter of Credit Agreement and the terms of this Agreement, the terms of this Agreement shall control.

The Issuing Bank shall not be under any obligation to issue any Letter of Credit if: (x) any order, judgment or decree of any Governmental Authority or arbitrator shall by its terms purport to enjoin or restrain the Issuing Bank from issuing the Letter of Credit, or any law applicable to the Issuing Bank or any request or directive (whether or not having the force of law) from any Governmental Authority with jurisdiction over the Issuing Bank shall prohibit, or request that the Issuing Bank refrain from, the issuance of letters of credit generally or the Letter of Credit in particular or shall impose upon the Issuing Bank with respect to the Letter of Credit any restriction, reserve or capital requirement (for which the Issuing Bank is not otherwise compensated hereunder) not in effect on the Effective Date, or shall impose upon the Issuing Bank any unreimbursed loss, cost or expense which was not applicable on the Effective Date and which the Issuing Bank in good faith deems material to it, or (y) the issuance of the Letter of Credit would violate one or more policies of the Issuing Bank applicable to letters of credit generally.

Upon at least one (1) Business Day’s prior written notice (or telephonic notice promptly confirmed in writing) to the Administrative Agent and the Issuing Bank (which notice the

Administrative Agent shall promptly transmit to each of the Lenders), the Borrower shall have the right, on any day, permanently to terminate the LC Commitment in whole or in part; provided that, after giving effect to such termination or reduction, the outstanding LC Exposure shall not exceed the LC Commitment.

(i) Each Letter of Credit shall expire (the “LC Maturity Date”) at or prior to the close of business on the earlier of (A) the date that is one year after the date of the issuance of such Letter of Credit (or fifteen (15) months with respect to Letters of Credit issued for the benefit of the Texas Railroad Commission or such longer period as the Issuing Bank may agree in its sole discretion), or in the case of any renewal or extension thereof, one year after such renewal or extension (or fifteen (15) months with respect to Letters of Credit issued for the benefit of the Texas Railroad Commission or such longer period as the Issuing Bank may agree in its sole discretion) and (B) the date that is five Business Days prior to the Maturity Date.

(ii) If the Borrower so requests, the Issuing Bank may, in its sole and absolute discretion, agree to issue a Letter of Credit that has automatic extension provisions (each, an “Auto-Extension Letter of Credit”); provided that any such Auto-Extension Letter of Credit must permit the Issuing Bank to prevent any such extension at least once in each 12-month period (commencing with the date of issuance of such Letter of Credit) by giving prior notice to the beneficiary thereof not later than a day (the “Non-Extension Notice Date”) in each such 12-month period to be agreed upon at the time such Letter of Credit is issued. Once an Auto-Extension Letter of Credit has been issued, the Lenders shall be deemed to have authorized (but may not require) the Issuing Bank to permit the extension of such Letter of Credit at any time to an expiry date not later than the date that is five Business Days prior to the Maturity Date; provided, however, that the Issuing Bank shall not permit any such extension if (A) the Issuing Bank has determined that it would not be permitted, or would have no obligation, at such time to issue such Letter of Credit in its revised form (as extended) under the terms hereof (by reason of the provisions of Section 2.08(a) or otherwise), or (B) it has received notice (which may be by telephone, email or in writing) on or before the day that is five Business Days before the Non-Extension Notice Date (I) from the Administrative Agent that the Majority Lenders have elected not to permit such extension or (II) from the Administrative Agent, any Lender or the Borrower that one or more of the applicable conditions specified in Section 6.02 are not then satisfied, and in each such case directing the Issuing Bank not to permit such extension.

(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 Section 2.08(e), 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 Section 2.08(d) 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, the existence of a Borrowing Base Deficiency or any reduction or termination of the Commitments, 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 not later than 2:00 p.m., New York City time by paying to the Administrative Agent an amount equal to such LC Disbursement 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., New York City time, 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 2:00 p.m., New York City time on (i) the Business Day that the Borrower receives such notice, if such notice is received prior to 10:00 a.m., New York City time, on the day of receipt, or (ii) the Business Day immediately following the day that the Borrower receives such notice, if such notice is not received prior to such time on the day of receipt; provided that the Borrower shall, subject to the conditions to Borrowing set forth herein, be deemed to have requested, and the Borrower does hereby request under such circumstances, 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 (and Borrower’s failure to make such reimbursement payment shall not constitute a payment Default hereunder). If the Borrower fails to make such reimbursement payment when due, or is unable to finance such payment with an ABR Borrowing because it cannot satisfy the conditions in Section 6.02, 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 2.05 with respect to Loans made by such Lender (and Section 2.05 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 Section 2.08(e), the Administrative Agent shall distribute such payment to the Issuing Bank or, to the extent that Lenders have made payments pursuant to this Section 2.08(e) 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 Section 2.08(e) 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.

(f) Obligations Absolute. The Borrower’s obligation to reimburse LC Disbursements as provided in Section 2.08(e) 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, any Letter of Credit Agreement 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 any Letter of Credit Agreement, 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 2.08(f), 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 (i) 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 or (ii) be construed to excuse the Administrative Agent, the Lenders, the Issuing Bank, or any of their Related Parties from liability for its own gross negligence or willful misconduct. 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 all requisite 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 email or fax) 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.

(h) Interim Interest. If the Issuing Bank shall make any LC Disbursement, then, until the Borrower shall have reimbursed the Issuing Bank for such LC Disbursement (either with its own funds or a Borrowing under Section 2.08(e)), 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. Interest accrued pursuant to this Section 2.08(h) 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 Section 2.08(e) 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 3.05(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 the Issuing Bank hereunder, the replaced Issuing Bank shall remain a party hereto and shall continue to have all the rights and obligations of the 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. If (i) any Event of Default shall occur and be continuing and the Borrower receives notice from the Administrative Agent indicating that the Required Lenders require the deposit of cash collateral pursuant to this Section 2.08(j) or (ii) the Borrower is required to pay to the Administrative Agent the excess attributable to an LC Exposure in connection with any prepayment pursuant to Section 3.04(c), then the Borrower shall deposit, in an account with the Administrative Agent, in the name of the Administrative Agent and for the benefit of the Lenders, an amount in cash equal to, in the case of an existing Event of Default, the LC Exposure, and in the case of a payment required by Section 3.04(c), the amount of such excess as provided in Section 3.04(c), as of such date; 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 or any Restricted Subsidiary described in Section 10.01(h) or Section 10.01(i). The Borrower hereby grants to the Administrative Agent, for the benefit of the Issuing Bank and the Lenders, an exclusive first priority and continuing perfected security interest in and Lien on such account and all cash, checks, drafts, certificates and instruments, if any, from time to time deposited or held in such account, all deposits or wire transfers made thereto, any and all investments purchased with funds deposited in such account, all interest, dividends, cash, instruments, financial assets and other Property from time to time received, receivable or otherwise payable in respect of, or in exchange for, any or all of the foregoing, and all proceeds, products, accessions, rents, profits, income and benefits therefrom, and any substitutions and replacements therefor. The Borrower’s obligation to deposit amounts pursuant to this Section 2.08(j) shall be absolute and unconditional, without regard to whether any beneficiary of any such Letter of Credit has attempted to draw down all or a portion of such amount under the terms of a Letter of Credit, and, to the fullest extent permitted by applicable law, shall not be subject to any defense or be affected by a right of set-off, counterclaim or recoupment which the Borrower or any of its Subsidiaries may now or hereafter have against any such beneficiary, the Issuing Bank, the Administrative Agent, the Lenders or any other Person for any reason whatsoever. Such deposit shall be held as collateral securing the payment and performance of the Borrower’s and the

Guarantor’s obligations under this Agreement and the other Loan Documents. The Administrative Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account. Other than any interest earned on the investment of such deposits, which 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 such 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, be applied to satisfy other obligations of the Borrower and the Guarantors under this Agreement or the other Loan Documents. If the Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence and continuance of an Event of Default, and the Borrower is not otherwise required to pay to the Administrative Agent the excess attributable to an LC Exposure in connection with any prepayment pursuant to Section 3.04(c), then such amount (to the extent not applied as aforesaid) shall be returned to the Borrower within two Business Days after all Events of Default have been cured or waived.

(k) Applicability of ISP. Unless otherwise expressly agreed by the Issuing Bank and the Borrower when a Letter of Credit is issued, the rules of the ISP shall apply to each Letter of Credit. Notwithstanding the foregoing, the Issuing Bank shall not be responsible to the Borrower for, and the Issuing Bank’s rights and remedies against the Borrower shall not be impaired by, any action or inaction of the Issuing Bank required or permitted under any law, order, or practice that is required or permitted to be applied to any Letter of Credit or this Agreement, including the law or any order of a jurisdiction where the Issuing Bank or the beneficiary is located, the practice stated in the ISP or in the decisions, opinions, practice statements, or official commentary of the ICC Banking Commission, the Bankers Association for Finance and Trade – International Financial Services Association (BAFT-IFSA), or the Institute of International Banking Law & Practice, whether or not any Letter of Credit chooses such law or practice.

(l) Defaulting Lenders. If, at any time, a Defaulting Lender exists hereunder, then, within one (1) Business Day following the written request of the Issuing Bank, the Borrower shall cash collateralize the Fronting Exposure of the Issuing Bank with respect to such Defaulting Lender (determined after giving effect to Section 2.11(a)(iv) and any cash collateral provided by such Defaulting Lender) with respect to the Defaulting Lender in an amount equal to the lesser of (x) the amount of such Fronting Exposure and (y ) an amount otherwise agreeable to the Issuing Bank and the Administrative Agent in their sole discretion.

(i) Grant of Security Interest. The Borrower and, to the extent provided by any Defaulting Lender, such Defaulting Lender, hereby grants to the Administrative Agent, for the benefit of the Issuing Bank, and agrees to maintain, a first priority security interest in all such cash collateral as security for the Defaulting Lenders’ obligation to fund participations in respect of LC Exposure, to be applied pursuant to clause (ii) below. Such Borrower or Defaulting Lender, as applicable, shall execute any documents and agreements, including the Administrative Agent’s standard form assignment of deposit accounts, that the Administrative Agent reasonably requests in

connection therewith to establish such cash collateral account and to grant the Administrative Agent, for the benefit of the Issuing Bank, a first priority security interest in such account and the funds therein. If at any time the Administrative Agent determines that cash collateral is subject to any right or claim of any Person other than the Administrative Agent and the Issuing Bank as herein provided, or that the total amount of such cash collateral is less than the amount required under Section 2.08(l) above, the Borrower will, promptly upon demand by the Administrative Agent, pay or provide to the Administrative Agent additional cash collateral in an amount sufficient to eliminate such deficiency (after giving effect to any cash collateral provided by the Defaulting Lender).

(ii) Application. Notwithstanding anything to the contrary contained in this Agreement, cash collateral provided under this Section 2.08(l) or Section 2.11 in respect of Letters of Credit shall be applied to the satisfaction of the Defaulting Lender’s obligation to fund participations in respect of LC Exposure (including, as to cash collateral provided by a Defaulting Lender, any interest accrued on such obligation) for which the cash collateral was so provided, prior to any other application of such property as may otherwise be provided for herein.

(iii) Termination of Requirement. Cash collateral (or the appropriate portion thereof) provided to reduce the Issuing Bank’s Fronting Exposure shall no longer be required to be held as cash collateral pursuant to this Section 2.08(l) following (A) the elimination of the applicable Fronting Exposure (including by the termination of Defaulting Lender status of the applicable Lender), or (B) the determination by the Administrative Agent and the Issuing Bank that there exists excess cash collateral; provided that, subject to Section 2.11, (x) the Issuing Bank may determine in its sole discretion that cash collateral provided by a Defaulting Lender shall be held to support future anticipated Fronting Exposure or other obligations of such Defaulting Lender and (y) the Borrower and the Issuing Bank may agree that cash collateral provided by the Borrower shall be held to support future anticipated Fronting Exposure or other obligations; and provided further that to the extent that such cash collateral was provided by the Borrower, such cash collateral shall remain subject to the security interest granted pursuant to the Loan Documents.

(m) LC Exposure Determination. For all purposes of this Agreement, the amount of a Letter of Credit that, by its terms or the terms of any document related thereto, provides for one or more automatic increases in the stated amount thereof shall be deemed to be the maximum stated amount of such Letter of Credit after giving effect to all such increases, whether or not such maximum stated amount is in effect at the time of determination.

Section 2.09 Swingline Loans.

(a) Availability. Subject to the terms and conditions set forth herein, the Swingline Lender agrees to make Swingline Loans to the Borrower from time to time during the Availability Period; provided that (i) after giving effect to any amount requested, the total Revolving Credit Exposures shall not exceed the Loan Limit and (ii) the aggregate principal amount of all outstanding Swingline Loans (after giving effect to any amount requested), shall

not exceed the Swingline Commitment; and provided further that no Swingline Loan may be requested to refinance any outstanding Swingline Loan. Within the foregoing limits and subject to the terms and conditions set forth herein, the Borrower may borrow, repay and reborrow the Swingline Loans. Each Swingline Loan shall be a LIBOR Market Index Rate Loan. Immediately upon the making of a Swingline Loan, each Lender with a Commitment shall be deemed to, and hereby irrevocably and unconditionally agrees to, purchase from the Swingline Lender a risk participation in such Swingline Loan in an amount equal to the product of such Lender’s Applicable Percentage times the amount of such Swingline Loan.

(b) Borrowing Procedures. Each Borrowing of Swingline Loans may be made upon the Borrower’s irrevocable notice to the Swingline Lender and the Administrative Agent, which may be given by telephone. Each such notice must be received by the Swingline Lender and the Administrative Agent not later than 1:00 p.m., New York City time, on the requested borrowing date, and shall specify (i) the amount to be borrowed, which shall be a minimum of $500,000 or a whole multiple of $100,000 in excess thereof and (ii) the requested borrowing date, which shall be a Business Day. Each such telephonic notice must be confirmed promptly by delivery to the Swingline Lender and the Administrative Agent of a written Borrowing Request in substantially the form of Exhibit B and signed by the Borrower. Promptly after receipt by the Swingline Lender of any telephonic Borrowing Request, the Swingline Lender will confirm with the Administrative Agent (by telephone or in writing) that the Administrative Agent has also received such Borrowing Request and, if not, the Swingline Lender will notify the Administrative Agent (by telephone or in writing) of the contents thereof. Unless the Swingline Lender has received notice (by telephone or in writing) from the Administrative Agent (including at the request of any Lender) prior to 2:00 p.m., New York City time, on the date of the proposed Borrowing of Swingline Loans (A) directing the Swingline Lender not to make such Swingline Loan as a result of the limitations set forth in the first proviso to the first sentence of Section 2.09(a) or (2) that one or more of the applicable conditions specified in Section 6.02 is not then satisfied, then, subject to the terms and conditions hereof, the Swingline Lender will, not later than 3:00 p.m., New York City time, on the borrowing date specified in such Borrowing Request, make the amount of its Swingline Loan available to the Borrower.

The Swingline Lender shall not be under any obligation to issue any Swingline Loan if: (x) any order, judgment or decree of any Governmental Authority or arbitrator shall by its terms purport to enjoin or restrain the Swingline Lender from making Swingline Loans, or any law applicable to the Swingline Lender or any request or directive (whether or not having the force of law) from any Governmental Authority with jurisdiction over the Swingline Lender shall prohibit, or request that the Swingline Lender refrain from, the making of swing line loans generally or the Swingline Loans in particular or shall impose upon the Swingline Lender with respect to the Swingline Loans any restriction, reserve or capital requirement (for which the Issuing Bank is not otherwise compensated hereunder) not in effect on the Effective Date, or shall impose upon the Swingline Lender any unreimbursed loss, cost or expense which was not applicable on the Effective Date and which the Swingline Lender in good faith deems material to it, or (y) the issuance of the Swingline Loans would violate one or more policies of the Swingline Lender applicable to swing line loans generally.

(i) The Swingline Lender at any time in its sole discretion may request, on behalf of the Borrower (which hereby irrevocably authorizes the Swingline Lender to so request on their behalf), that each Lender make a Revolving Loan in an amount equal to such Lender’s Applicable Percentage of the amount of Swingline Loans then outstanding. Additionally, if a Swingline Loan is not repaid by Borrower on or before the date required for such Swingline Loan under Section 3.01, Borrower shall, subject to the conditions set forth in Section 6.02 herein, be deemed to have requested, and the Borrower does hereby request under such circumstances, that such Swingline Loan be refinanced with an ABR Borrowing in an equivalent amount and, to the extent so financed, the Borrower’s obligation to repay such Swingline Loan shall be discharged and replaced by the resulting ABR Borrowing. If the Borrower does not repay a Swingline Loan when due, and instead requests (or is deemed to have requested pursuant to the terms hereof) that such payment be refinanced with a Revolving Loan, (i) the Administrative Agent shall request that each Lender make a Revolving Loan in an amount equal to such Lender’s Applicable Percentage of the amount of such Swingline Loan and (ii) Borrower’s failure to repay such Swingline Loan on the date required by Section 3.01 shall not constitute a payment Default hereunder. Any such request hereunder from the Administrative Agent shall be made in writing (which written request shall be deemed to be a Borrowing Request for purposes hereof) and in accordance with the requirements of Section 2.03, without regard to the minimum and multiples specified in Section 2.02(c) for the principal amount of such Loans, but subject to the conditions set forth in Section 6.02, and provided that the after giving effect to such Borrowing, the total Revolving Credit Exposures shall not exceed the Loan Limit. The Swingline Lender shall furnish the Borrower with a copy of the applicable Borrowing Request promptly after delivering such notice to the Administrative Agent. Each Lender shall make an amount equal to its Applicable Percentage of the amount specified in such Borrowing Request available to the Administrative Agent in immediately available funds (and the Administrative Agent may apply cash collateral available with respect to the applicable Swingline Loan) for the account of the Swingline Lender at the Administrative Agent’s Office not later than 1:00 p.m., New York City time, on the day specified in such Borrowing Request, whereupon, subject to Section 2.09(c)(ii), each Lender that so makes funds available shall be deemed to have made a Revolving Loan to the Borrower in such amount. The Administrative Agent shall remit the funds so received to the Swingline Lender.

(ii) If for any reason any Swingline Loan cannot be refinanced by such a Revolving Loan in accordance with Section 2.09(c)(i), the request for Revolving Loans submitted by the Swingline Lender as set forth herein shall be deemed to be a request by the Swingline Lender that each of the Lenders fund its risk participation in the relevant Swingline Loan and each Lender’s payment to the Administrative Agent for the account of the Swingline Lender pursuant to Section 2.09(c)(i) shall be deemed payment in respect of such participation.

(iii) If any Lender fails to make available to the Administrative Agent for the account of the Swingline Lender any amount required to be paid by such Lender

pursuant to the foregoing provisions of this Section 2.09(c) by the time specified in Section 2.09(c)(i), the Swingline Lender shall be entitled to recover from such Lender (acting through the Administrative Agent), on demand, such amount with interest thereon for the period from the date such payment is required to the date on which such payment is immediately available to the Swingline Lender at a rate per annum equal to the greater of the Federal Funds Effective Rate and a rate determined by the Swingline Lender in accordance with banking industry rules on interbank compensation, plus any administrative, processing or similar fees customarily charged by the Swingline Lender in connection with the foregoing. If such Lender pays such amount (with interest and fees as aforesaid), the amount so paid shall constitute such Lender’s Revolving Loan included in the relevant Borrowing or funded participation in the relevant Swingline Loan, as the case may be. A certificate of the Swingline Lender submitted to any Lender (through the Administrative Agent) with respect to any amounts owing under this clause (iii) shall be conclusive absent manifest error.

(iv) Each Lender’s obligation to make Revolving Loans or to purchase and fund risk participations in Swingline Loans pursuant to this Section 2.09(c) shall be absolute and unconditional and shall not be affected by any circumstance, including (A) any setoff, counterclaim, recoupment, defense or other right which such Lender may have against the Swingline Lender, the Borrower or any other Person for any reason whatsoever, (B) the occurrence or continuance of a Default or an Event of Default, or (C) any other occurrence, event or condition, whether or not similar to any of the foregoing; provided, however, that each Lender’s obligation to make Revolving Loans pursuant to this Section 2.09(c) is subject to the conditions set forth in Section 6.02. No such funding of risk participations shall relieve or otherwise impair the obligation of the Borrower to repay Swingline Loans, together with interest as provided herein.

(d) Repayment of Participations.

(i) At any time after any Lender has purchased and funded a risk participation in a Swingline Loan, if the Swingline Lender receives any payment on account of such Swingline Loan, the Swingline Lender will distribute to such Lender its Applicable Percentage (appropriately adjusted, in the case of interest payments, to reflect the period of time during which such Lender’s risk participation was funded) thereof in the same funds as those received by the Swingline Lender.

(ii) If any payment received by the Swingline Lender in respect of principal or interest on any Swingline Loan is required to be returned by the Swingline Lender under any of the circumstances described in Section 12.05(b) (including pursuant to any settlement entered into by the Swingline Lender in its discretion), each Lender shall pay to the Swingline Lender its Applicable Percentage thereof on demand of the Administrative Agent, plus interest thereon from the date of such demand to the date such amount is returned, at a rate per annum equal to the Federal Funds Effective Rate. The Administrative Agent will make such demand upon the request of the Swingline Lender. The obligations of the Lenders under this clause shall survive the payment in full of the Indebtedness and the termination of this Agreement.

(e) Interest for Account of Swingline Lender. The Swingline Lender shall be responsible for invoicing the Borrower for interest on the Swingline Loans. Until each Lender funds its Revolving Loans or risk participation pursuant to this Section 2.09 to refinance such Lender’s Applicable Percentage of any Swingline Loan, interest in respect of such Applicable Percentage shall be solely for the account of the Swingline Lender.

(f) Payments Directly to Swingline Lender. The Borrower shall make all payments of principal and interest in respect of the Swingline Loans directly to the Swingline Lender.

(g) Resignation of Swingline Lender. The Swingline Lender may resign at any time by giving 30 days’ prior notice to the Administrative Agent, the Lenders and the Borrower. After the resignation of a Swingline Lender hereunder, the retiring Swingline Lender shall remain a party hereto and shall continue to have all the rights and obligations of a Swingline Lender under this Agreement and the other Loan Documents with respect to Swingline Loans made by it prior to such resignation, but shall not be required to make any additional Swingline Loans.

Section 2.10 Increase in Aggregate Commitment.

(a) At (i) any time that is not an Investment Grade Period, if the Borrowing Base exceeds the Aggregate Commitment, or (ii) any time during an Investment Grade Period, the Borrower may, by written notice to the Administrative Agent, request one or more increases in the Aggregate Commitment (an “Incremental Commitment”); provided that (i) at any time that is not an Investment Grade Period, no Incremental Commitment shall exceed an amount equal to the Borrowing Base at the time of such request minus the Aggregate Commitment (prior to giving effect to such Incremental Commitment) at such time, (ii) no such Incremental Commitment shall be permitted if after giving effect thereto, the Aggregate Commitment would exceed the Maximum Aggregate Amount, and (iii) the total amount of each Incremental Commitment shall be in a minimum principal amount of $10,000,000 (unless, at any time that is not an Investment Grade Period, prior to giving effect to such increase, the Borrowing Base exceeds the Aggregate Commitment by less than $10,000,000 and after giving effect to such increase, the Aggregate Commitment will equal the Borrowing Base). Each such notice shall specify the date (each, an “Increase Date”) on which the Borrower proposes that any Incremental Commitment shall be effective, which shall be a date not less than five (5) Business Days after the date on which such notice is delivered to Administrative Agent. The Borrower may invite (x) any Lender, any Affiliate of any Lender and/or any Approved Fund (an “Increase Lender”), and/or (y) any other Person (other than an Affiliate of the Borrower) reasonably satisfactory to the Administrative Agent, the Issuing Bank and the Swingline Lender to provide an Incremental Commitment (any such Person, an “Additional Lender”). Any Increase Lender or any Additional Lender offered or approached to provide all or a portion of any Incremental Commitment may elect or decline, in its sole discretion, to provide such Incremental Commitment. Any Incremental Commitment shall become effective as of such Increase Date; provided that:

(i) the Borrower may not, during any period that is not an Investment Grade Period, request more than one increase in the Aggregate Commitment between

Scheduled Redetermination dates, it being understood that an increase in the Aggregate Commitment may also be requested on any Scheduled Redetermination date (for the sake of clarity, all increases in the Aggregate Commitment effective on a single day shall be deemed a single increase in the Aggregate Commitment for purposes of this subsection);

(ii) no Default or Event of Default shall exist on such Increase Date before or after giving effect to any Incremental Commitment and the making of any Loans pursuant thereto;

(iii) no Lender’s Commitment may be increased without the consent of such Lender;

(iv) all of the terms and conditions applicable to such Incremental Commitments (and the Loans made pursuant thereto) shall be identical to the terms and conditions applicable to Commitments and Loans under this Agreement (other than with respect to any arrangement, structuring, upfront or other fees or discounts payable in connection with such Incremental Commitment as may have been agreed to between the Borrower and the Increase Lender or Additional Lender, as applicable, and/or the Administrative Agent);

(v) if the Borrower elects to increase the Aggregate Commitment by increasing the Commitment of one or more Increase Lenders, the Borrower and each such Increase Lender shall execute and deliver to the Administrative Agent a certificate substantially in the form of Exhibit J (a “Commitment Increase Certificate”) and the Borrower shall pay any applicable fees as may have been agreed to between the Borrower and such Increase Lender and/or the Administrative Agent;

(vi) if the Borrower elects to increase the Aggregate Commitment by causing one or more Additional Lenders to become a party to this Agreement, then the Borrower and each such Additional Lender shall execute and deliver to the Administrative Agent a certificate substantially in the form of Exhibit K (an “Additional Lender Certificate”), together with an Administrative Questionnaire and a processing and recordation fee of $3,500 for each Additional Lender, which shall be payable by the Borrower to the Administrative Agent unless waived by the Administrative Agent, and the Borrower shall (A) if requested by any Additional Lender, deliver a Note payable to such Additional Lender in a principal amount equal to its Commitment, and otherwise duly completed and (B) pay any applicable fees as may have been agreed to between the Borrower and any Additional Lender and/or the Administrative Agent;

(vii) the Borrower shall deliver or cause to be delivered any customary legal opinions or other documents (including, without limitation, a resolution duly adopted by the board of directors (or equivalent governing body) of each Credit Party authorizing such Incremental Commitment) reasonably requested by Administrative Agent; and

(viii) after giving effect to the Incremental Commitments, (A) the Aggregate Commitment shall be increased automatically on the Increase Date by the

aggregate amount indicated in the Commitment Increase Certificates and/or Additional Lender Certificates, as applicable, without further action by the Borrower, the Administrative Agent, the Swingline Lender, the Issuing Bank or any Lender, (B) Annex I and the Register shall each be amended to reflect the increase in the Commitment of an Increase Lender or to add such Additional Lender’s Commitment, as applicable, and the Applicable Percentages of the Lenders shall be adjusted accordingly to reflect any Incremental Commitment of an Increase Lender and/or each Additional Lender, (C) the Administrative Agent shall distribute to the Borrower, the Administrative Agent, the Swingline Lender, the Issuing Bank and each Lender such revised Annex I, (D) 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 (E) the outstanding Revolving Loans, Swingline Loans and LC Exposure will be reallocated by the Administrative Agent on the applicable Increase Date among the Lenders and/or the Additional Lenders, as applicable, in accordance with their revised Applicable Percentages (and (x) the Lenders and/or Additional Lenders, as applicable, shall make all payments and adjustments necessary to effect such reallocation, and (y) the Borrower shall pay any and all costs required pursuant to Section 5.02 in connection with such reallocation as if such reallocation were a repayment).

Section 2.11 Defaulting Lenders.

(a) Defaulting Lender Adjustments. Notwithstanding anything to the contrary contained in this Agreement, if any Lender becomes a Defaulting Lender, then, until such time as such Lender is no longer a Defaulting Lender, to the extent permitted by applicable law:

(i) Waivers and Amendments. Such Defaulting Lender’s right to approve or disapprove any amendment, waiver or consent with respect to this Agreement shall be restricted as set forth in the definitions of “Borrowing Base Increase Lenders”, “Required Lenders” and “Majority Lenders”.

(ii) Defaulting Lender Waterfall. Any payment of principal, interest, fees or other amounts received by the Administrative Agent for the account of such Defaulting Lender (whether voluntary or mandatory, at maturity, pursuant to Article X or otherwise) shall be applied at such time or times as may be determined by the Administrative Agent as follows: first, to the payment of any amounts owing by such Defaulting Lender to the Administrative Agent hereunder; second, to the payment on a pro rata basis of any amounts owing by such Defaulting Lender to the Issuing Bank or Swingline Lender hereunder; third, to cash collateralize the Issuing Bank’s Fronting Exposure with respect to such Defaulting Lender in accordance with Section 2.08(l); fourth, as the Borrower may request (so long as no Default or Event of Default exists), to the funding of any Loan in respect of which such Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Administrative Agent; fifth, if so determined by the Administrative Agent and the Borrower, to be held in a deposit account and released pro rata in order to (x) satisfy such Defaulting Lender’s potential future funding obligations with respect to Loans under this Agreement and (y) cash collateralize the Issuing Bank’s future Fronting Exposure with respect to such

Defaulting Lender with respect to future Letters of Credit issued under this Agreement, in accordance with Section 2.08(l); sixth, to the payment of any amounts owing to the Lenders, the Issuing Bank and the Swingline Lender as a result of any judgment of a court of competent jurisdiction obtained by any Lender, the Issuing Bank or the Swingline Lender against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; seventh, so long as no Default or Event of Default exists, to the payment of any amounts owing to the Borrower as a result of any judgment of a court of competent jurisdiction obtained by the Borrower against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; and eighth, to such Defaulting Lender or as otherwise directed by a court of competent jurisdiction; provided that if (x) such payment is a payment of the principal amount of any Loans or LC Exposure in respect of which such Defaulting Lender has not fully funded its appropriate share, and (y) such Loans were made or the related Letters of Credit were issued at a time when the conditions set forth in Section 6.02 were satisfied or waived, such payment shall be applied solely to pay the Loans of, and Letter of Credit obligations owed to, all Non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Loans of, or LC Exposure owed to, such Defaulting Lender until such time as all Loans and funded and unfunded participations in LC Exposure and Swingline Loans are held by the Lenders pro rata in accordance with the Commitments without giving effect to Section 2.11(a)(iv). Any payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender or to post cash collateral pursuant to this Section 2.11(a)(ii) shall be deemed paid to and redirected by such Defaulting Lender, and each Lender irrevocably consents hereto.

(iii) Certain Fees.

(A) No Defaulting Lender shall be entitled to receive any commitment fee pursuant to Section 3.05(a) for any period during which that Lender is a Defaulting Lender (and the Borrower shall not be required to pay any such fee that otherwise would have been required to have been paid to that Defaulting Lender).

(B) Each Defaulting Lender shall be entitled to receive fees pursuant to Section 3.05(b) for any period during which that Lender is a Defaulting Lender only to the extent allocable to its Applicable Percentage of the stated amount of Letters of Credit for which it has provided cash collateral pursuant to Section 2.08(l).

(C) With respect to any fee pursuant to Section 3.05(b) not required to be paid to any Defaulting Lender pursuant to clause (B) above, the Borrower shall (x) pay to each Non-Defaulting Lender that portion of any such fee otherwise payable to such Defaulting Lender with respect to such Defaulting Lender’s participation in Letter of Credit obligations or Swingline Loans that has been reallocated to such Non-Defaulting Lender pursuant to clause (iv) below, (y) pay to the Issuing Bank or Swingline Lender, as applicable, the amount of any such fee otherwise payable to such Defaulting Lender to the extent allocable to the Issuing Bank’s or Swingline Lender’s Fronting Exposure to such Defaulting Lender, and (z) not be required to pay the remaining amount of any such fee.

(iv) Reallocation of Participations to Reduce Fronting Exposure. All or any part of such Defaulting Lender’s participation in LC Exposure and Swingline Loans shall be reallocated among the Non-Defaulting Lenders in accordance with their respective Applicable Percentages (calculated without regard to such Defaulting Lender’s Commitment) but only to the extent that (x) the conditions set forth in Section 6.02 are satisfied at the time of such reallocation (and, unless the Borrower shall have otherwise notified the Administrative Agent at such time, the Borrower shall be deemed to have represented and warranted that such conditions are satisfied at such time), and (y) such reallocation does not cause the Revolving Credit Exposure of any Non-Defaulting Lender to exceed such Non-Defaulting Lender’s Commitment then in effect. No reallocation hereunder shall constitute a waiver or release of any claim of any party hereunder against a Defaulting Lender arising from that Lender having become a Defaulting Lender, including any claim of a Non-Defaulting Lender as a result of such Non-Defaulting Lender’s increased exposure following such reallocation.

(v) Cash Collateral. If the reallocation described in clause (iv) above cannot, or can only partially, be effected, the Borrower shall, without prejudice to any right or remedy available to it hereunder or under law, (A) first, prepay Swingline Loans in an amount equal to the Swingline Lender’s Fronting Exposure and (B) second, cash collateralize the Issuing Bank’s Fronting Exposure in accordance with the procedures set forth in Section 2.08(l).

(b) Defaulting Lender Cure. If the Borrower, the Administrative Agent, the Swingline Lender and the Issuing Bank agree in writing that a Lender is no longer a Defaulting Lender, the Administrative Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include arrangements with respect to any cash collateral), that Lender will, to the extent applicable, purchase at par that portion of outstanding Loans of the other Lenders or take such other actions as the Administrative Agent may determine to be necessary to cause the Loans and funded and unfunded participations in Letters of Credit to be held pro rata by the Lenders in accordance with the Commitments (without giving effect to Section 2.11(a)(iv)), whereupon such Lender will cease to be a Defaulting Lender; provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrower while that Lender was a Defaulting Lender; and provided, further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender.

(c) New Letters of Credit and Swingline Loans. So long as any Lender is a Defaulting Lender, (i) the Swingline Lender shall not be required to fund any Swingline Loans unless it is satisfied that it will have no Fronting Exposure after giving effect to such Swingline Loan and (ii) the Issuing Bank shall not be required to issue, extend, renew or increase any Letter of Credit unless it is satisfied that it will have no Fronting Exposure after giving effect thereto.

ARTICLE III

PAYMENTS OF PRINCIPAL AND INTEREST; PREPAYMENTS; FEES

Section 3.01 Repayment of Loans. The Borrower hereby unconditionally promises to pay to the Administrative Agent for the account of each Lender the then unpaid principal amount of each Revolving Loan on the Termination Date. The Borrower shall repay each Swingline Loan (or refinance such Swingline Loan with a Revolving Loan pursuant to Section 2.09(c)) on the earlier to occur of (i) the date ten Business Days after such Swingline Loan is made and (ii) the Termination Date.

Section 3.02 Interest.

(a) ABR Loans. The Loans comprising each ABR Borrowing shall bear interest at the Alternate Base Rate plus the Applicable Margin, but in no event to exceed the Highest Lawful Rate.

(b) Eurodollar Loans. 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 Margin, but in no event to exceed the Highest Lawful Rate.

(c) Swingline Loans. Each Borrowing of Swingline Loans shall bear interest at the LIBOR Market Index Rate plus the Applicable Margin, but in no event to exceed the Highest Lawful Rate.

(d) Post-Default Rate. Notwithstanding the foregoing, (i) if any Event of Default of the type described in Section 10.01(a), Section 10.01(b), Section 10.01(h), Section 10.01(i) or Section 10.01(j) occurs and is continuing, then all outstanding principal, fees and other obligations under any Loan Document shall automatically bear interest at a rate per annum of two percent (2%) plus the rate applicable to ABR Loans as provided in Section 3.02(a) (including the Applicable Margin), but in no event to exceed the Highest Lawful Rate, and shall be payable on demand by the Administrative Agent and (ii) if any Event of Default occurs and continues (other than an Event of Default described in Section 10.01(a), Section 10.01(b), Section 10.01(h), Section 10.01(i) or Section 10.01(j)), then at the election of the Required Lenders (or the Administrative Agent at the direction of Required Lenders), all outstanding principal, fees and other obligations under any Loan Document shall bear interest at a rate per annum of two percent (2%) plus the rate applicable to ABR Loans as provided in Section 3.02(a) (including the Applicable Margin), but in no event to exceed the Highest Lawful Rate, and shall be payable on demand by the Administrative Agent.

(e) Interest Payment Dates. Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan and on the Termination Date; provided that (i) interest accrued pursuant to Section 3.02(d) shall be payable on demand, (ii) in the event of any repayment or prepayment of any Loan (other than an optional prepayment of an ABR Loan prior to the Termination Date), 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.

(f) Interest Rate Computations. All interest hereunder shall be computed on the basis of a year of 360 days, unless such computation would exceed the Highest Lawful Rate, in which case interest shall be computed on the basis of a year of 365 days (or 366 days in a leap year), 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, LIBOR Market Index Rate, Adjusted LIBO Rate or LIBO Rate shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error, and be binding upon the parties hereto.

Section 3.03 Alternate Rate of Interest. If prior to the commencement of any Interest Period for a Eurodollar Borrowing:

(a) the Administrative Agent or the Required Lenders determine (which determination shall be conclusive absent manifest error) that, because of changes arising on or after the Effective Date affecting the interbank LIBOR market, adequate and reasonable means do not exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate for such Interest Period; or

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

then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by telephone, email or fax 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 either as an ABR Borrowing or at an alternate rate of interest determined by the Required Lenders in good faith as their cost of funds.

Section 3.04 Prepayments.

(a) Optional Prepayments. The Borrower shall have the right at any time and from time to time to prepay any Borrowing in whole or in part, subject to prior notice in accordance with Section 3.04(b).

(b) Notice and Terms of Optional Prepayment. The Borrower shall notify the Administrative Agent by telephone (confirmed by email or fax) of any prepayment hereunder (i) in the case of prepayment of a Eurodollar Borrowing, not later than 12:00 noon, New York City time, three Business Days before the date of prepayment, (ii) in the case of prepayment of an ABR Borrowing, not later than 12:00 noon, New York City time, on the date of prepayment or (iii) in the case of prepayment of a Swingline Loan, not later than 12:00 noon, New York City time, one 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 of the Commitments as contemplated by Section 2.06(b), then such notice of prepayment may be revoked if such notice of termination is revoked in accordance with Section 2.06(b). 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 Borrowing of the same Type as provided in Section 2.02(c), or with respect to prepayments of Swingline Loans, Section 2.09(b). 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 3.02.

(i) If, after giving effect to any termination or reduction of the Aggregate Commitment pursuant to Section 2.06(b), the total Revolving Credit Exposures exceeds the Loan Limit (as so reduced), then the Borrower shall (A) prepay the Borrowings on the date of such termination or reduction in an aggregate principal amount equal to such excess, and (B) if as a result of an LC Exposure any excess remains after prepaying all of the Borrowings, pay to the Administrative Agent on behalf of the Lenders an amount equal to such excess to be held as cash collateral as provided in Section 2.08(j).

(ii) Upon any redetermination of or adjustment to the amount of the Borrowing Base in accordance with Section 2.07 (other than pursuant to Section 2.07(e) or Section 2.07(f)) or Section 8.12(c), if a Borrowing Base Deficiency shall result therefrom, then the Borrower shall eliminate such Borrowing Base Deficiency by electing to (w) make such prepayment and/or deposit of cash collateral in an aggregate principal amount equal to such Borrowing Base Deficiency within thirty (30) days after such redetermination or adjustment, (x) repay such Borrowing Base Deficiency in six (6) equal and consecutive monthly installments, the first installment being due and payable 30 days after receipt of Administrative Agent’s notice of the new Borrowing Base and each subsequent installment being due and payable on the same day in each of the 5 subsequent calendar months, (y) provide additional Oil and Gas Properties or other collateral acceptable to the Borrowing Base Increase Lenders (together with title information with respect thereto acceptable to the Administrative Agent) to increase the Borrowing Base by an amount at least equal to such Borrowing Base Deficiency; or (z) effect any combination of the foregoing clauses (w), (x) and (y) in amounts necessary to eliminate such Borrowing Base Deficiency; provided that all payments required to be made pursuant to this Section 3.04(c)(ii) must be made on or prior to the Termination Date. The Borrower shall make such election in writing to the Administrative Agent within thirty (30) days after Borrower’s receipt of the Administrative Agent’s notice of the new Borrowing Base. If a Borrowing Base Deficiency remains after prepaying all of the Borrowings as a result of an LC Exposure, the Borrower shall pay to the Administrative Agent on behalf of the Lenders an amount equal to such Borrowing Base Deficiency to be held as cash collateral as provided in Section 2.08(j). Notwithstanding the foregoing, no mandatory prepayment under this Section 3.04(c)(ii) shall be required during any Investment Grade Period.

(iii) Upon any adjustments to the Borrowing Base pursuant to Section 2.07(f), if a Borrowing Base Deficiency shall result therefrom, then the Borrower shall (A) prepay the Borrowings in an aggregate principal amount equal to such Borrowing Base Deficiency, and (B) if any Borrowing Base Deficiency remains after prepaying all of the Borrowings as a result of an LC Exposure, pay to the Administrative Agent on behalf of the Lenders an amount equal to such Borrowing Base Deficiency to be held as cash collateral as provided in Section 2.08(j). The Borrower shall be obligated to make the foregoing prepayment and/or deposit of cash collateral prior to or contemporaneously with the closing date of the applicable disposition or Liquidation. Notwithstanding the foregoing, no mandatory prepayment under this Section 3.04(c)(iii) shall be required during any Investment Grade Period.

(iv) Upon any adjustments to the Borrowing Base pursuant to Section 2.07(e), if a Borrowing Base Deficiency shall result therefrom, then the Borrower shall (A) prepay the Borrowings in an aggregate principal amount equal to such Borrowing Base Deficiency, and (B) if any excess remains after prepaying all of the Borrowings as a result of an LC Exposure, pay to the Administrative Agent on behalf of the Lenders an amount equal to such Borrowing Base Deficiency to be held as cash collateral as provided in Section 2.08(j). The Borrower shall be obligated to make such prepayment and/or deposit of cash collateral required by this Section 3.04(c)(iv) on the date it issues such Senior Notes. Notwithstanding the foregoing, no mandatory prepayment under this Section 3.04(c)(iv) shall be required during any Investment Grade Period.

(v) If for any reason the aggregate outstanding principal amount of all Swingline Loans at any time exceeds the Swingline Commitment, the Borrower shall immediately prepay Swingline Loans in an aggregate amount equal to such excess.

(vi) Each prepayment of Borrowings pursuant to this Section 3.04(c) shall be applied, first, ratably to any Swingline Loans then outstanding, second, ratably to any ABR Borrowings then outstanding, and, third, to any Eurodollar Borrowings then outstanding, and if more than one Eurodollar Borrowing is then outstanding, to each such Eurodollar Borrowing in order of priority 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 days remaining in the Interest Period applicable thereto.

(vii) Each prepayment of Borrowings pursuant to this Section 3.04(c) shall be applied ratably to the Loans included in the prepaid Borrowings. Prepayments pursuant to this Section 3.04(c) shall be accompanied by accrued interest to the extent required by Section 3.02.

(d) No Premium or Penalty. Prepayments permitted or required under this Section 3.04 shall be without premium or penalty, except as required under Section 5.02.

Section 3.05 Fees.

(a) Commitment Fees. The Borrower agrees to pay to the Administrative Agent for the account of each Lender (other than a Defaulting Lender pursuant to Section 2.11(a)(iii)(A)) a commitment fee, which shall accrue at the applicable Commitment Fee Rate on the average daily amount of the unused amount of the Commitment of such Lender during the period from and including the date of this Agreement to but excluding the Termination Date; provided, that the amount of outstanding Swingline Loans shall not be considered usage of the Commitments for the purpose of calculating such fee. Accrued commitment fees shall be payable in arrears on the last day of March, June, September and December of each year and on the Termination Date, commencing on the first such date to occur after the date hereof. All commitment fees shall be computed on the basis of a year of 360 days, unless such computation would exceed the Highest Lawful Rate, in which case such fees shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

(b) Letter of Credit Fees. 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 Margin 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 date of this Agreement 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, (ii) to the Issuing Bank a fronting fee at the rate separately agreed upon between the Borrower and the Issuing Bank, 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 date of this Agreement to but excluding the later of the date of termination of the Commitments and the date on which there ceases to be any LC Exposure and (iii) to the Issuing Bank, for its own account, its standard fees with respect to the issuance, amendment, renewal or extension of any Letter of Credit or processing of drawings thereunder, in the amounts separately agreed upon between the Borrower and the Issuing Bank. Participation 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 date of this Agreement; provided that all such fees shall be payable on the Termination Date and any such fees accruing after the Termination Date shall be payable on demand. Any other fees payable to the Issuing Bank pursuant to this Section 3.05(b) shall be payable within 10 days after demand. All participation and fronting fees shall be computed on the basis of a year of 360 days, unless such computation would exceed the Highest Lawful Rate, in which case such fees shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

(c) Administrative Agent Fees. The Borrower agrees to pay to the Administrative Agent, for its own account, fees payable in the amounts and at the times separately agreed upon between the Borrower and the Administrative Agent.

ARTICLE IV

PAYMENTS; PRO RATA TREATMENT; SHARING OF SET-OFFS

Section 4.01 Payments Generally; Pro Rata Treatment; Sharing of Set-offs.

(a) Payments by the Borrower. 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 5.01, Section 5.02, Section 5.03 or otherwise) prior to 2:00 p.m., New York City time, on the date when due, in immediately available funds, without defense, deduction, recoupment, set-off or counterclaim. Fees, once paid, shall be fully earned and shall not be refundable under any circumstances. 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 specified in Section 12.01, except payments to be made directly to the Issuing Bank or Swingline Lender as expressly provided herein and except that payments pursuant to Section 5.01, Section 5.02, Section 5.03 and Section 12.03 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) Application of Insufficient Payments. 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 and fees 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.

(c) Sharing of Payments by Lenders. If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans or participations in LC Disbursements and Swingline Loans resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and participations in LC Disbursements and Swingline Loans 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 and Swingline Loans 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 and Swingline Loans; 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 Section 4.01(c) 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 and Swingline Loans to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this Section 4.01(c) 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.

Section 4.02 Presumption of Payment by the Borrower. 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 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 has 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.

Section 4.03 Certain Deductions by the Administrative Agent. If any Lender shall fail to make any payment required to be made by it pursuant to Section 2.05(a), Section 2.08(d), Section 2.08(e), Section 2.09(c), Section 2.09(d) or Section 4.02, or otherwise hereunder, then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid. After acceleration or maturity of the Loans, all principal will be paid ratably as provided in Section 10.02(c).

Section 4.04 Disposition of Proceeds. The Security Instruments contain an assignment by the Borrower and/or the Guarantors unto and in favor of the Administrative Agent for the benefit of the Secured Parties of all of the Borrower’s or each Guarantor’s interest in and to production and all proceeds attributable thereto which may be produced from or allocated to the Mortgaged Property. The Security Instruments further provide in general for the application of such proceeds to the satisfaction of the Indebtedness and other obligations described therein and secured thereby. Notwithstanding the assignment contained in such Security Instruments, unless an Event of Default exists, (a) the Administrative Agent and the Lenders agree that they will neither notify the purchaser or purchasers of such production nor take any other action to cause such proceeds to be remitted to the Administrative Agent or the Lenders, but the Lenders will instead permit such proceeds to be paid to the Borrower and its Restricted Subsidiaries and (b) the Lenders hereby authorize the Administrative Agent to take such actions as may be necessary to cause such proceeds to be paid to the Borrower and/or such Restricted Subsidiaries.

ARTICLE V

INCREASED COSTS; BREAK FUNDING PAYMENTS; TAXES; ILLEGALITY

Section 5.01 Increased Costs.

(a) Eurodollar Changes in Law. 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;

(ii) subject any Lender or the Issuing Bank to any Taxes (other than (A) Indemnified Taxes, (B) Taxes described in subparagraphs (ii) through (iv) of the definition of Excluded Taxes or (C) Connection Income Taxes) on its loans, loan principal, letters of credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto; or

(iii) impose on any Lender or the Issuing Bank or the London interbank market any other condition (other than Taxes) affecting this Agreement or Eurodollar Loans made by such Lender or any Letter of Credit issued by the Issuing Bank;

and the result of any of the foregoing shall be to increase the cost to such Lender or the Issuing Bank of making or maintaining any Eurodollar Loan or issuing any Letter of Credit (or of maintaining its obligation to make any such Loan or Letter of Credit) or to reduce the amount of any sum received or receivable by such Lender or Issuing Bank (whether of principal, interest or otherwise), then upon request of such Lender or the Issuing Bank, the Borrower will pay to such Lender or the Issuing Bank, as applicable, 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) Capital Requirements. If any Lender or the Issuing Bank determines that any Change in Law affecting such Lender or the Issuing Bank regarding capital or liquidity 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 Bank’s holding company with respect to capital adequacy and liquidity), 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) Certificates. A certificate of a Lender or the Issuing Bank setting forth the amount or amounts necessary to compensate such Lender or the Issuing Bank or its holding company, as the case may be, as specified in Section 5.01(a) or (b) shall be delivered to the

Borrower and 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) Effect of Failure or Delay in Requesting Compensation. Failure or delay on the part of any Lender or the Issuing Bank to demand compensation pursuant to this Section 5.01 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 5.01 for any increased costs or reductions incurred more than 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 5.02 Break Funding Payments. In the event of (a) the payment by Borrower 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 into an ABR 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 by the Borrower pursuant hereto, or (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 5.04(b), then, in any such event, the Borrower shall after the Borrower’s receipt of a written request from any Lender (which request shall set forth in reasonable detail the basis for requesting such amount and the amount that such Lender is entitled to receive, which shall be conclusive absent manifest error) pay to such Lender (within fifteen days after such request) any amounts required to compensate such Lender for any additional loss, cost and expense that such Lender may reasonably incur as a result of such event, including any loss, cost or expense (excluding loss of anticipated profits) actually incurred by reason of the liquidation or reemployment of deposits or other funds acquired by any Lender to fund or maintain such Eurodollar Loan.

Section 5.03 Taxes.

(a) Payments Free of Taxes. Any and all payments by or on account of any obligation of the Borrower or any Guarantor under any Loan Document shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes (except as required by applicable law); provided that if the Borrower or any Guarantor shall be required to deduct any Indemnified Taxes or Other Taxes from such payments (as determined in good faith by a Credit Party), then (i) the sum payable by Borrower or such Guarantor shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 5.03(a)), 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 or such Guarantor shall make such deductions and (iii) the Borrower or such Guarantor shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

(b) Payment of Other Taxes by the Borrower. The Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(c) Indemnification by the Borrower. 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 payable or 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 imposed or asserted on or attributable to amounts payable under this Section 5.03) and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate of the Administrative Agent, a Lender or the Issuing Bank as to the amount of such payment or liability under this Section 5.03 shall be delivered to the Borrower and shall be conclusive absent manifest error.

(d) Indemnification by the Lenders. Each Lender shall severally indemnify the Administrative Agent, within 10 days after demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that Borrower has not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of the Borrower to do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 12.04(c) relating to the maintenance of a Participant Register and (iii) any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by the Administrative Agent in connection with any Loan Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Lender by the Administrative Agent shall be conclusive absent manifest error. Each Lender hereby authorizes the Administrative Agent to set off and apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by the Administrative Agent to the Lender from any other source against any amount due to the Administrative Agent under this paragraph (d).

(e) Evidence of Payments. As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower or a Guarantor to a Governmental Authority pursuant to this Section 5.03, 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.

(f) Status of Lenders. (i) Any Lender that is entitled to an exemption from or reduction of withholding tax with respect to payments made under any Loan Document shall deliver to the Withholding Agent, at the time or times reasonably requested by the Withholding Agent, such properly completed and executed documentation reasonably requested by the Withholding Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender shall deliver such other documentation prescribed by applicable law or reasonably requested by the Withholding Agent as will enable the Withholding Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding

two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Section 5.03(f)(ii)(A) and Section 5.03(f)(ii)(B) and Section 5.03(g) below) shall not be required if in the Lender’s reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender.

(ii) Without limiting the generality of the foregoing, in the event that the Borrower is a “United States Person” as defined in Section 7701(a)(30) of the Code (a “U.S. Person”),

(A) any Lender that is a U.S. Person shall deliver to the Withholding Agent on or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Withholding Agent), executed originals of IRS Form W-9 certifying that such Lender is exempt from U.S. federal backup withholding tax;

(B) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Withholding Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Withholding Agent), whichever of the following is applicable:

(1) in the case of a Foreign Lender claiming the benefits of an income tax treaty to which the United States is a party (x) with respect to payments of interest under any Loan Document, executed originals of IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “interest” article of such tax treaty and (y) with respect to any other applicable payments under any Loan Document, IRS Form W-8BEN establishing an exemption from, or reduction of, U.S. federal withholding tax pursuant to the “business profits” or “other income” article of such tax treaty;

(2) executed originals of IRS Form W-8ECI;

(3) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code, (x) a certificate substantially in the form of Exhibit I-1 to the effect that such Foreign Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, a “10 percent shareholder” of the Borrower within the meaning of Section 871(h)(3)(B) of the Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code (a “U.S. Tax Compliance Certificate”) and (y) executed originals of IRS Form W-8BEN; or

(4) to the extent a Foreign Lender is not the beneficial owner, executed originals of IRS Form W-8IMY, accompanied by IRS

Form W-8ECI, IRS Form W-8BEN, a U.S. Tax Compliance Certificate substantially in the form of Exhibit I-2 or Exhibit I-3, IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign Lender are claiming the portfolio interest exemption, such Foreign Lender may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit I-4 on behalf of each such direct and indirect partner; and

(C) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Withholding Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Withholding Agent), executed originals of any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in U.S. federal withholding tax, duly completed, together with such supplementary documentation as may be prescribed by applicable law to permit the Withholding Agent to determine the withholding or deduction required to be made.

Each Lender agrees that if any form or certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the Withholding Agent in writing of its legal inability to do so.

(g) FATCA. If a payment made to a Lender under any Loan Document would be subject to United States federal withholding tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Withholding Agent, at the time or times prescribed by law and at such time or times reasonably requested by the Withholding Agent, such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Withholding Agent as may be necessary for the Withholding Agent to comply with its obligations under FATCA, to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this Section 5.03(g), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

(h) Treatment of Certain Refunds. If any party determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section 5.03 (including by the payment of additional amounts pursuant to this Section 5.03), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such indemnified party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over pursuant to this

paragraph (h) (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event that such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this paragraph (h), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this paragraph (h) the payment of which would place the indemnified party in a less favorable net after-Tax position than the indemnified party would have been in if the Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax had never been paid. This paragraph shall not be construed to require any indemnified party to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the indemnifying party or any other Person.

(i) For the avoidance of doubt, (A) the term “Lender” in this Section 5.03 includes the Issuing Bank and the Swingline Lender and (B) for the purposes of this Section 5.03, the term “applicable law” includes FATCA.

Section 5.04 Mitigation Obligations; Replacement of Lenders.

(a) Designation of Different Lending Office. If any Lender requests compensation under Section 5.01, or if the Borrower is required to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 5.03, then such Lender shall (at the request of Borrower) 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 5.01 or Section 5.03, 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) Replacement or Removal of Lenders. If (i) any Lender requests compensation under Section 5.01, (ii) the Borrower is required to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 5.03, (iii) any Lender becomes a Defaulting Lender hereunder, (iv) any Lender becomes a Non-Consenting Lender or (v) any Lender provides a notice pursuant to Section 5.05, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, (A) require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 12.04(b)), all of its interests, rights and obligations under this Agreement and the related Loan Documents to an Eligible Assignee that shall assume such obligations (which Eligible Assignee may be another Lender, if a Lender accepts such assignment) or (B) remove such Lender by terminating its Commitment hereunder (and the Aggregate Commitment shall be automatically reduced by such amount); provided that (1) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and participations in LC Disbursements and Swingline Loans, 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, or in the case of removal of such Lender, all

amounts) and (2) in the case of any such assignment resulting from a claim for compensation under Section 5.01 or payments required to be made pursuant to Section 5.03, such assignment will result in a reduction in such compensation or payments thereafter. A Lender shall not be required to make any such assignment or delegation, or be subject to removal, 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 or removal cease to apply. Notwithstanding the foregoing, a Lender shall not be required to make any such assignment and delegation or be subject to removal if such Lender is a Secured Swap Provider with any outstanding Swap Agreements with any Credit Party (to the extent obligations under such Swap Agreements constitute Indebtedness), unless on or prior thereto, all such Swap Agreements have been terminated or novated to another Approved Counterparty and such Lender (or its Affiliate) shall have received payment of all amounts, if any, payable to it in connection with such termination or novation.

Section 5.05 Illegality. Notwithstanding any other provision of this Agreement, in the event that it becomes unlawful for any Lender or its applicable lending office to honor its obligation to make or maintain Eurodollar Loans either generally or having a particular Interest Period hereunder, then (a) such Lender shall promptly notify the Borrower and the Administrative Agent thereof and such Lender’s obligation to make such Eurodollar Loans shall be suspended (the “Affected Loans”) until such time as such Lender may again make and maintain such Eurodollar Loans and (b) all Affected Loans which would otherwise be made by such Lender shall be made instead as ABR Loans (and, if such Lender so requests by notice to the Borrower and the Administrative Agent, all Affected Loans of such Lender then outstanding shall be automatically converted into ABR Loans on the date specified by such Lender in such notice) and, to the extent that Affected Loans are so made as (or converted into) ABR Loans, all payments of principal which would otherwise be applied to such Lender’s Affected Loans shall be applied instead to its ABR Loans.

in full force and effect its legal existence and the rights, licenses, permits, privileges and franchises material to the conduct of its business and maintain, if necessary, its qualification to do business in each other jurisdiction in which its Oil and Gas Properties are located or the ownership of its Properties requires such qualification, except where the failure to so qualify would not reasonably be expected to have a Material Adverse Effect; provided that the foregoing shall not prohibit any merger, consolidation, liquidation or dissolution permitted under Section 9.05, Section 9.11 or Section 9.12.

Section 8.04 Payment of Obligations. The Borrower will, and will cause each Restricted Subsidiary to, pay its obligations, including Tax liabilities of the Borrower and all of its Subsidiaries before the same shall become delinquent or in default, except where (a) the validity or amount thereof is being contested in good faith by appropriate proceedings, (b) the Borrower or such Restricted Subsidiary has set aside on its books adequate reserves with respect thereto to the extent required by and in accordance with GAAP and (c) the failure to make payment pending such contest would not reasonably be expected to result in a Material Adverse Effect or result in the seizure or levy of any material Property of the Borrower or any Restricted Subsidiary.

Section 8.05 Operation and Maintenance of Properties. The Borrower, at its own expense, will, and will cause each Restricted Subsidiary, except in each case, where the failure to do so, either individually or in the aggregate, would not reasonably be expected to have a Material Adverse Effect, to:

(a) operate its Oil and Gas Properties and other Properties or cause such Oil and Gas Properties and other Properties to be operated in a careful and efficient manner in accordance with the customary practices of the industry and in compliance with all applicable contracts and agreements and in compliance with all Governmental Requirements, including applicable proration requirements and Environmental Laws, and all applicable laws, rules and regulations of every other Governmental Authority from time to time constituted to regulate the development and operation of its Oil and Gas Properties and the production and sale of Hydrocarbons and other minerals therefrom;

The loss payable clauses or provisions in said insurance policy or policies insuring any of the collateral for the Loans shall be endorsed in favor of and made payable to the Administrative Agent as its interests may appear and such policies shall name the Administrative Agent and the Lenders as “additional insureds” or “lender’s loss payee”, as applicable, and provide that the insurer will endeavor to give at least thirty (30) days prior notice of any cancellation to the Administrative Agent. The insurance hereunder shall be maintained with, in the good faith judgment of Borrower, financially sound and reputable insurance companies or through self-insurance, and may be subject to co-insurance, deductibility or similar clauses which, in effect, result in self-insurance of certain losses, provided that such self-insurance is in accordance with the customary practices of business enterprises of established reputation similarly situated, and adequate insurance reserves are maintained in connection with such self-insurance, and, notwithstanding the foregoing provisions of this Section 8.06, any Credit Party may effect workers’ compensation or similar insurance in respect of operations in any state or any other jurisdiction through an insurance fund operated by such state or other jurisdiction by causing to be maintained a system or systems of self-insurance in accordance with applicable laws.

Section 8.07 Books and Records; Inspection Rights. The Borrower will, and will cause each Restricted Subsidiary to, keep proper books of record and account in which full, true and correct entries in conformity with GAAP consistently applied shall be made for all financial transactions and matters involving the assets and business of the Borrower and its Restricted Subsidiaries. The Borrower will, and will cause each Restricted Subsidiary to, permit any representatives designated by the Administrative Agent or any Lender, upon reasonable prior notice, to visit and inspect its Properties, to examine and make extracts from its books and records (in each case, subject to compliance with reasonable confidentiality agreements and requirements and applicable copyright laws), and to discuss its affairs, finances and condition with its officers and independent accountants, all at such reasonable times during normal business hours and as often as reasonably requested (but, unless an Event of Default exists, no more frequently than once during any calendar year at the expense of the Borrower), upon reasonable advance notice to the Borrower; provided, however, (i) unless an Event of Default exists, only the Administrative Agent on behalf of the Lenders may exercise the rights of the Administrative Agent and Lenders under this Section 8.07 and (ii) if an Event of Default exists, the Administrative Agent or any Lender may do any of the foregoing at the expense of the Borrower at any time during normal business hours without advance notice. Notwithstanding

anything to the contrary in this Section 8.07 or Section 8.01(n), neither the Borrower nor any Restricted Subsidiary will be required to disclose, permit the inspection, examination or making copies and abstracts of, or discuss any document, information or other matter (x) that constitutes non-financial trade secrets or non-financial proprietary information, (y) in respect of which disclosure to the Administrative Agent or any Lender (or their respective representatives or contractors) is prohibited by any Governmental Requirements or any binding agreement or (z) that is subject to attorney-client privilege or constitutes attorney work product.

Section 8.08 Compliance with Laws. The Borrower will, and will cause each Restricted Subsidiary to, comply with all laws, rules, regulations and orders of any Governmental Authority applicable to it or its Property, except where the failure to do so, individually or in the aggregate, would not reasonably be expected to result in a Material Adverse Effect. The Borrower will maintain in effect and enforce policies and procedures designed to ensure compliance by the Borrower, its Subsidiaries and their respective directors, officers, employees and agents with Anti-Corruption Laws and applicable Sanctions.

Section 8.09 Environmental Matters. The Borrower shall at its sole expense: (i) comply, and shall cause its Properties and operations and each Credit Party and each other Credit Party’s Properties and operations to comply, with all applicable Environmental Laws, except where the failure to so comply would not reasonably be expected to have a Material Adverse Effect; (ii) not Release, and shall cause each other Credit Party not to Release, any Hazardous Material on, under, about or from any of the Borrower’s or the other Credit Parties’ Properties or any other Property to the extent caused by the Borrower’s or any other Credit Party’s operations except and unless (x) in material compliance with applicable Environmental Laws, (y) such Credit Party promptly commences and diligently prosecutes to completion any assessment, evaluation, investigation, monitoring, containment, cleanup, removal, repair, restoration, remediation or other remedial obligations (collectively, the “Remedial Work”) in the event any Remedial Work is required by applicable Environmental Laws because of or in connection with such Release or (z) such Release (and the failure to conduct Remedial Work in connection therewith) would not reasonably be expected to have a Material Adverse Effect; (iii) timely obtain or file, and shall cause each other Credit Party to timely obtain or file, all Environmental Permits, if any, required under applicable Environmental Laws to be obtained or filed in connection with the operation or use of the Borrower’s or any other Credit Party’s Properties, which failure to obtain or file would reasonably be expected to have a Material Adverse Effect.

Section 8.10 Further Assurances.

(a) Subject to the applicable limitations set forth in the Security Instruments, the Borrower at its sole expense will, and will cause each Restricted Subsidiary to, promptly execute and deliver to the Administrative Agent all such other documents, agreements and instruments reasonably requested by the Administrative Agent to perfect, protect or preserve any Liens created pursuant to this Agreement or any of the Security Instruments or the priority thereof, or to make any recordings, file any notices or obtain any consents, all as may be reasonably necessary or appropriate, in the reasonable discretion of the Administrative Agent, in connection therewith. Notwithstanding anything herein to the contrary, if the Administrative Agent determines (in its sole discretion) that the cost of creating or perfecting any Lien on any Property is excessive in relation to the benefits afforded to the Lenders thereby, then such Property may be excluded from the Collateral for all purposes of the Loan Documents.

(b) The Borrower hereby authorizes the Administrative Agent to file one or more financing or continuation statements, and amendments thereto, relative to all or any part of the Mortgaged Property without the signature of the Borrower or any other Guarantor where permitted by law. A carbon, photographic or other reproduction of the Security Instruments or any financing statement covering the Mortgaged Property or any part thereof shall be sufficient as a financing statement where permitted by law. The Borrower acknowledges and agrees that any such financing statement filed in connection with the Guarantor Security Agreement may describe the collateral as “all assets” of the applicable Guarantor or words of similar effect as may be required by the Administrative Agent. Any financing statement filed in connection with the Borrower Security Agreement shall use the collateral description included in the Borrower Security Agreement.

Section 8.11 Reserve Reports.

(a) On or before March 1st and September 1st of each year, commencing March 1, 2015, the Borrower shall furnish to the Administrative Agent (for distribution to the Lenders) a Reserve Report evaluating the proved Oil and Gas Properties of the Credit Parties as of the immediately preceding December 31st and June 30^th, respectively. Each Reserve Report as of December 31^st (each, a “Year-End Reserve Report”) shall be prepared, at the Borrower’s election (i) by or under the supervision of the senior reservoir engineer of the Credit Parties and be audited by one or more Approved Petroleum Engineers; provided that so long as the audit covers at least 80% of the total value of the proved Oil and Gas Properties set forth in such Reserve Report, the remaining value may be covered by a report prepared by or under the supervision of the senior reservoir engineer of the Credit Parties or (ii) by one or more Approved Petroleum Engineers; provided so long such report covers at least 80% of the total value of the proved Oil and Gas Properties set forth in the Reserve Report, with the remaining value covered by a report prepared by or under the supervision of the senior reservoir engineer of the Credit Parties. Each Reserve Report as of June 30 shall be prepared by or under the supervision of the senior reservoir engineer of the Credit Parties, who shall certify such Reserve Report to be true and accurate and to have been prepared in accordance with the procedures used in the immediately preceding Year-End Reserve Report.

(b) In the event of an Interim Redetermination, the Borrower shall furnish to the Administrative Agent (for distribution to the Lenders) a Reserve Report prepared by or under the supervision of the senior reservoir engineer of the Credit Parties who shall certify such Reserve Report to be true and accurate and to have been prepared in accordance with the procedures used in the immediately preceding Year-End Reserve Report. For any Interim Redetermination requested by the Administrative Agent or the Borrower pursuant to Section 2.07(b), the Borrower shall provide such Reserve Report with an “as of” date as required by the Administrative Agent as soon as possible, but in any event no later than thirty (30) days, in the case of any Interim Redetermination requested by Borrower, or forty-five (45) days, in the case of any Interim Redetermination requested by the Administrative Agent or the Lenders, following the receipt of such request.

(c) With the delivery of each Reserve Report, the Borrower shall provide to the Administrative Agent (for delivery to the Lenders) a certificate from a Responsible Officer certifying that in all material respects: (i) the Reserve Report and any other written information delivered in connection therewith have been prepared in good faith, and to the knowledge of such officer, there are no statements or conclusions therein which are based upon or include misleading information or fail to take into account material information regarding the matters reported therein (it being understood that projections concerning volumes attributable to the Oil and Gas Properties of the Borrower and the Restricted Subsidiaries and production costs and estimates contained therein are based upon professional opinions, estimates and projections and that the Borrower and the Restricted Subsidiaries do not warrant that such professional opinions, estimates and projections will ultimately prove to have been correct), (ii) the Borrower or a Restricted Subsidiary owns good and defensible title to the Oil and Gas Properties evaluated in such Reserve Report (other than Oil and Gas Properties that have been sold in accordance with the terms and conditions of this Agreement and are set forth on an exhibit to the certificate, which exhibit shall list such Oil and Gas Properties in such detail as is reasonably required by the Administrative Agent) and such Properties are free of all Liens except for Excepted Liens and Liens securing the Indebtedness, (iii) except as set forth on an exhibit to the certificate, on a net basis there are no gas imbalances, take or pay or other prepayments in excess of the volume specified in Section 7.18 with respect to its Oil and Gas Properties evaluated in such Reserve Report which would require the Borrower or any Restricted Subsidiary to deliver Hydrocarbons either generally or produced from such Oil and Gas Properties at some future time without then or thereafter receiving full payment therefor, (iv) none of their Oil and Gas Properties have been sold since the date of the last Borrowing Base determination except as set forth on an exhibit to the certificate, which certificate shall list all of its Oil and Gas Properties sold and in such detail as reasonably required by the Administrative Agent and (v) the Borrower has reviewed the Reserve Report and the then-current Mortgaged Properties and ascertained that Mortgaged Properties represent at least 80% of the PV-9 of the Oil and Gas Properties evaluated in such Reserve Report in compliance with Section 8.13(a).

(d) During an Investment Grade Period, the Borrower will not be required to comply with this Section 8.11, so long as the Borrower has both (i) an unsecured rating from Moody’s of Baa3 or better and (ii) an unsecured rating from S&P of BBB- or better.

Section 8.12 Title Information. At any time that is not an Investment Grade Period:

(a) on or before the delivery to the Administrative Agent of each Reserve Report required by Section 8.11(a), the Borrower will deliver, if requested by the Administrative Agent, title information consistent with usual and customary standards for the geographic region in which the Borrowing Base Properties are located (taking into account the size, scope and number of leases and wells of the Borrower and the other Credit Parties), covering enough of the Oil and Gas Properties evaluated by such Reserve Report that were not included in the immediately preceding Reserve Report, so that the Administrative Agent shall have received together with title information previously delivered to the Administrative Agent, satisfactory title information on at least 80% of the total value of the Oil and Gas Properties evaluated by such Reserve Report.

(b) If the Borrower has provided title information for additional Properties under Section 8.12(a), the Borrower shall, within sixty (60) days after notice from the Administrative Agent that title defects or exceptions exist with respect to such additional Properties, either (i) cure any such title defects or exceptions (including defects or exceptions as to priority) which are not permitted by Section 9.03 raised by such information, (ii) substitute acceptable Mortgaged Properties with no title defects or exceptions (other than Excepted Liens) having an equivalent or higher value or (iii) deliver title information in form and substance reasonably acceptable to the Administrative Agent so that the Administrative Agent shall have received, together with title information previously delivered to the Administrative Agent, satisfactory title information on at least 80% of the value of the Oil and Gas Properties evaluated by such Reserve Report.

(c) If the Borrower is unable to cure any title defect requested by the Administrative Agent or the Lenders to be cured within the sixty (60) day period or the Borrower does not comply with the requirements to provide acceptable title information covering 80% of the value of the Oil and Gas Properties evaluated in the most recent Reserve Report, such default shall not be a Default, but instead the Administrative Agent and/or the Required Lenders shall have the right to exercise the following remedy in their sole discretion from time to time, and any failure to so exercise this remedy at any time shall not be a waiver as to future exercise of the remedy by the Administrative Agent or the Lenders. To the extent that the Administrative Agent or the Required Lenders are not satisfied with title to any Mortgaged Property after the sixty (60) day period has elapsed, such unacceptable Mortgaged Property shall not count towards the 80% requirement, and the Administrative Agent may send a notice to the Borrower and the Lenders that the then outstanding Borrowing Base shall be reduced by an amount as determined by the Required Lenders to cause the Borrower to be in compliance with the requirement to provide acceptable title information on 80% of the value of the Oil and Gas Properties. This new Borrowing Base shall become effective immediately after receipt of such notice.

Section 8.13 Collateral and Guaranty Agreements.

(a) At any time that is not an Investment Grade Period, in connection with each redetermination (but not adjustment) of the Borrowing Base, the Borrower shall review the applicable Reserve Report and the current Mortgaged Properties to ascertain whether the Mortgaged Properties represent at least 80% of the PV-9 of the Oil and Gas Properties evaluated in the most recently completed Reserve Report after giving effect to exploration and production activities, acquisitions, dispositions and production. In the event that the Mortgaged Properties do not represent at least 80% of such PV-9, then the Borrower shall, and shall cause the other Credit Parties to, grant, within thirty (30) days of delivery of the certificate required under Section 8.11(c) (or such longer period as the Administrative Agent may agree in its reasonable discretion), to the Administrative Agent as security for the Indebtedness a first-priority Lien interest (provided that Excepted Liens may exist) on additional Oil and Gas Properties of the Credit Parties and which Oil and Gas Properties are not already subject to a Lien of the Security Instruments such that after giving effect thereto, the Mortgaged Properties will represent at least 80% of such PV-9. All such Liens will be created and perfected by and in accordance with the provisions of deeds of trust, mortgages, security agreements and financing statements or other Security Instruments, all in form and substance reasonably satisfactory to the Administrative Agent and in sufficient executed (and acknowledged where necessary or appropriate)

counterparts for recording purposes. In order to comply with the foregoing, if any Restricted Subsidiary places a Lien on its Oil and Gas Properties in favor of the Administrative Agent pursuant to the terms of the Loan Documents and such Restricted Subsidiary is not a Guarantor, then it shall become a Guarantor and comply with Section 8.13(b).

(b) In the event that (i) the Borrower determines that any Restricted Subsidiary is a Material Subsidiary, or (ii) the Borrower or any Restricted Subsidiary forms or acquires any Restricted Subsidiary that is a Material Subsidiary, the Borrower shall promptly cause such Restricted Subsidiary to guarantee the Indebtedness pursuant to the Guaranty Agreement. In connection with any such guaranty, the Borrower shall, or shall cause such Restricted Subsidiary to execute and deliver (A) a supplement to the Guaranty Agreement, (B) at any time that is not an Investment Grade Period, a supplement to the Guarantor Security Agreement executed by such Subsidiary, together with a pledge of all of the Equity Interests of such new Subsidiary unless not otherwise required pursuant to the applicable Security Agreement (including, to the extent applicable, delivery of original certificates evidencing the Equity Interests of such Subsidiary, together with an appropriate undated Equity Interest powers for each certificate duly executed in blank by the registered owner thereof) and (C) such other additional closing documents, certificates and legal opinions as shall reasonably be requested by the Administrative Agent. Notwithstanding anything to the contrary set forth herein, if the Immaterial Subsidiaries that are Restricted Subsidiaries and Wholly-Owned Subsidiaries have (1) aggregate revenues in any fiscal year exceeding 10% of the consolidated total revenues of the Borrower and its Subsidiaries or (2) aggregate total assets exceeding 10% of Total Assets, the Borrower shall, as soon as reasonably practicable, but in no event later than twenty (20) Business Days (as such deadline may be extended by the Administrative Agent in its sole discretion), cause one or more of such Subsidiaries to comply with the foregoing requirements of this Section 8.13(b), so that, after giving effect thereto, the Immaterial Subsidiaries which are Restricted Subsidiaries and Wholly-Owned Subsidiaries have aggregate revenues in any fiscal year less than or equal to 10% of the consolidated total revenues of the Borrower and its Subsidiaries and aggregate total assets of less than or equal to 10% of Total Assets.

(c) At any time that is not an Investment Grade Period, the Borrower will at all times cause the following Property to be subject to a Lien of the Security Instruments: (i) the other tangible and intangible personal Property of the Borrower and each Guarantor described in the applicable Security Agreement and (ii) such real Property of the Guarantors not constituting Oil and Gas Properties necessary so that the fair market value of all such non-mortgaged real Property does not exceed $25,000,000.

(d) Subject to any applicable limitations set forth in the Security Instruments, the Borrower will, within sixty (60) days of the end of any Investment Grade Period (or such longer period as the Administrative Agent may agree in its reasonable discretion), execute and cause its Restricted Subsidiaries to execute: (i) the applicable Security Agreement and any other documentation that may be required pursuant to Section 8.13(b) and (ii) any mortgages and any other documentation that may be required pursuant to Section 8.13(a) such that after giving effect thereto the Mortgaged Properties represent at least 80% of the PV-9 of the Oil and Gas Properties evaluated in the most recently completed Reserve Report.

(e) Notwithstanding any provision in any of the Loan Documents to the contrary, in no event is any Building (as defined in the applicable Flood Insurance Regulations) or Manufactured (Mobile) Home (as defined in the applicable Flood Insurance Regulations) owned by any Credit Party included in the Mortgaged Property and no Building or Manufactured (Mobile) Home shall be encumbered by any Security Instrument; provided, that (A) the applicable Credit Party’s interests in all lands and Hydrocarbons situated under any such Building or Manufactured (Mobile) Home shall be included in the Mortgaged Property and shall be encumbered by the Security Instruments and (B) the Borrower shall not, and shall not permit any of its Restricted Subsidiaries to, permit to exist any Lien on any Building or Manufactured (Mobile) Home except Excepted Liens and other than Liens permitted by Section 9.03.

(f) Notwithstanding any provision of this Agreement or of any other Loan Document to the contrary, so long as the Existing Indenture remains in effect, the Borrower shall not pledge or otherwise grant a Lien to the Administrative Agent for the benefit of the Secured Parties to secure the Indebtedness on any of its Property other than such Property that constitutes “Excepted Property”, as such term is defined in the Existing Indenture.

Section 8.14 ERISA Compliance. The Borrower will promptly furnish to the Administrative Agent upon becoming aware of the occurrence of a “prohibited transaction,” as described in section 406 of ERISA or in section 4975 of the Code, in connection with any Plan or any trust created thereunder, that would have a Material Adverse Effect or any ERISA Event that, when taken together will all other ERISA Events that have occurred on or after the Effective Date, would reasonably be expected to result in liability of the Borrower, its Subsidiaries or any ERISA Affiliates in an aggregate amount exceeding $50,000,000, a written notice signed by a Responsible Officer of the Borrower, the Subsidiary or the ERISA Affiliate, as the case may be, specifying the nature thereof, what action the Borrower, the Subsidiary or the ERISA Affiliate is taking or proposes to take with respect thereto, and, when known, any action taken or proposed by the Internal Revenue Service, the Department of Labor or the PBGC with respect thereto.

Section 8.15 Unrestricted Subsidiaries. The Borrower:

(a) will cause the management, business and affairs of each of the Borrower and its Restricted Subsidiaries to be conducted in such a manner (including by keeping separate books of account, furnishing separate financial statements of Unrestricted Subsidiaries to creditors and potential creditors thereof and by not permitting Properties of the Borrower and its respective Restricted Subsidiaries to be commingled with those of the Unrestricted Subsidiaries) so that each Unrestricted Subsidiary that is a corporation will be treated as a corporate entity separate and distinct from the Borrower and the Restricted Subsidiaries.

(b) will not, and will not permit any of the Restricted Subsidiaries to, incur, assume, guarantee or be or become liable for any Debt of any of the Unrestricted Subsidiaries.

(c) will not permit any Unrestricted Subsidiary to hold any Equity Interest in, or any Debt (other than Permitted Unrestricted Subsidiary Debt) of, the Borrower or any Restricted Subsidiary.

Section 8.16 Commodity Exchange Act Keepwell Provisions. The Borrower hereby guarantees the payment and performance of all Indebtedness of each Credit Party (other than the Borrower) and absolutely, unconditionally and irrevocably undertakes to provide such funds or other support as may be needed from time to time by each Credit Party (other than the Borrower) in order for such Credit Party to honor its obligations under its respective Guaranty Agreement including obligations with respect to Swap Agreements (provided, however, that the Borrower shall only be liable under this Section 8.16 for the maximum amount of such liability that can be hereby incurred without rendering its obligations under this Section 8.16, or otherwise under this Agreement or any Loan Document, as it relates to such other Credit Parties, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer, and not for any greater amount). The obligations of the Borrower under this Section 8.16 shall remain in full force and effect until all Indebtedness (excluding contingent indemnification obligations not due and payable) is paid in full to the Lenders, the Administrative Agent and all other Secured Parties (or, for purposes of Letters of Credit, such Letters of Credit are cash collateralized to the reasonable satisfaction of the Issuing Bank) and all of the Lenders’ Commitments are terminated. The Borrower intends that this Section 8.16 shall constitute, and this Section 8.16 shall be deemed to constitute, a “keepwell, support, or other agreement” for the benefit of each other Credit Party for all purposes of Section 1a(18)(A)(v)(II) of the Commodity Exchange Act.

ARTICLE IX

NEGATIVE COVENANTS

Until the Commitments have expired or terminated and the principal of and interest on each Loan and all fees payable hereunder and all other amounts payable under the Loan Documents have been paid in full and all Letters of Credit have expired or terminated (or cash collateralized on terms and conditions reasonably satisfactory to the Issuing Bank following the termination of the Commitments) and all LC Disbursements shall have been reimbursed, the Borrower covenants and agrees with the Lenders that:

Section 9.01 Financial Covenants.

(a) Ratio of Total Debt to EBITDAX. The Borrower will not, as of the last day of each fiscal quarter (each, a “Determination Date”), permit its ratio of Total Debt as of such Determination Date to EBITDAX for the four fiscal quarters ending on such Determination Date, to be greater than 4.0 to 1.0.

(b) Current Ratio. The Borrower will not permit, as of any Determination Date, its ratio of (i) consolidated current assets of the Borrower and its Consolidated Restricted Subsidiaries (including the Availability as of such Determination Date), but excluding non-cash assets under ASC 815) to (ii) consolidated current liabilities of the Borrower and its Consolidated Restricted Subsidiaries (excluding non-cash obligations under ASC 815 and current maturities under this Agreement), to be less than 1.0 to 1.0.

Section 9.17 Swap Agreements.

(a) Subject to Section 9.17(b), the Borrower will not, and will not permit any Restricted Subsidiary to, enter into any Swap Agreements with any Person other than:

(i) Swap Agreements with an Approved Counterparty in respect of commodities entered into not for speculative purposes (including Swap Agreements entered into to unwind or offset other permitted Swap Agreements) the notional volumes for which (when aggregated and netted with other commodity Swap Agreements then in effect other than basis differential swaps on volumes already hedged pursuant to other Swap Agreements) do not exceed, as of the date such Swap Agreement is entered into for each month during the period during which such Swap Agreement is in effect, (x) 85% of the reasonably anticipated production of crude oil (including natural gas liquids and condensate) and (y) 85% of the reasonably anticipated production of natural gas, in each case, as such production is projected from the Borrower’s and its Restricted Subsidiaries’ proved Oil and Gas Properties as set forth on the most recent Reserve Report delivered pursuant to the terms of this Agreement; provided, however, that (A) such Swap Agreements shall not, in any case, have a tenor of greater than five (5) years, and (B) (without duplication) the Borrower and its Restricted Subsidiaries shall be permitted to enter into Swap Agreements, trades or transactions with respect to reasonably anticipated production of natural gas liquids and condensate by entering into Swap Agreements, trades or transactions for crude oil on a conversion/equivalency basis based on the then-existing market price differential between a volume unit of crude oil to the same volume unit of natural gas liquids or condensate which conversion/equivalency calculation is reasonably acceptable to the Administrative Agent. It is understood that Swap Agreements in respect of commodities which may, from time to time, “hedge” the same volumes, but different elements of commodity risk thereof, shall not be aggregated together when calculating the foregoing limitations on notional volumes.

(ii) Swap Agreements in respect of interest rates with an Approved Counterparty, as follows:

(A) Swap Agreements effectively converting interest rates from fixed to floating, the notional amounts of which (when aggregated with all other Swap Agreements of the Borrower and its Restricted Subsidiaries then in effect effectively converting interest rates from fixed to floating) do not exceed 100% of the then anticipated maximum outstanding principal amount of the Credit Parties’ Debt for borrowed money which bears interest at a fixed rate, and which Swap Agreements shall not, in any case, have a tenor beyond the original stated maturity date of such Debt, and

(B) Swap Agreements effectively converting interest rates from floating to fixed, the notional amounts of which (when aggregated with all other Swap Agreements of the Borrower and its Restricted Subsidiaries then in effect effectively converting interest rates from floating to fixed) do not exceed 100% of the then anticipated maximum outstanding principal amount of the Credit Parties’ Debt for borrowed money which bears interest at a floating rate, and which Swap Agreements shall not, in any case, have a tenor beyond the original stated maturity date of such Debt.

110

(b) In no event shall any Swap Agreement contain any requirement, agreement or covenant for the Borrower or any Restricted Subsidiary to post collateral, credit support (including in the form of letters of credit, but excluding unsecured guarantees thereof to the extent permitted pursuant to Section 9.02) or margin, except for the Security Instruments, to secure their obligations under such Swap Agreement or to cover market exposures.

(c) It is understood that for purposes of this Section 9.17 the following Swap Agreements shall not be deemed speculative or entered into for speculative purposes: (i) any commodity Swap Agreement intended, at inception of execution, to hedge or manage any of the risks related to existing and/or forecasted Hydrocarbon production of the Borrower or its Restricted Subsidiaries (whether or not contracted) and (ii) any Swap Agreement intended, at inception of execution, (A) to hedge or manage the interest rate exposure associated with any Debt or leases (existing or forecasted) of the Borrower or its Restricted Subsidiaries, (B) for foreign exchange or currency exchange management, (C) to manage commodity portfolio exposure associated with changes in interest rates or (D) to hedge any exposure that the Borrower or its Restricted Subsidiaries may have to counterparties under other Swap Agreements such that the combination of such Swap Agreement is not speculative taken as a whole.

(d) The Borrower will not, and will not permit any Restricted Subsidiary to, Liquidate any Swap Agreement in respect of commodities without the prior written consent of the Required Lenders except to the extent such terminations are permitted pursuant to Section 9.12.

(e) For purposes of entering into or maintaining Swap Agreement trades or transactions under Section 9.17(a)(i), forecasts of reasonably anticipated production from the Borrower’s and its Restricted Subsidiaries’ proved Oil and Gas Properties as set forth on the most recent Reserve Report delivered pursuant to the terms of this Agreement shall be revised to account for any increase or decrease therein anticipated because of information obtained by the Borrower or any of its Restricted Subsidiaries subsequent to the publication of such Reserve Report including the Borrower’s or any of its Restricted Subsidiaries’ internal forecasts of production decline rates for existing wells and additions to or deletions from anticipated future production from new wells and completed acquisitions coming on stream or failing to come on stream.

Section 9.18 Non-Qualified ECP Guarantors. The Borrower shall not permit any Credit Party that is not a Qualified ECP Guarantor to own, at any time, any Oil and Gas Properties that are included in the Borrowing Base or any Equity Interests in any Subsidiaries owning Oil and Gas Properties that are included in the Borrowing Base.

Section 9.19 Repayment of Senior Notes; Amendment to Terms of Senior Notes; Repayment of Permitted Unrestricted Subsidiary Debt.

(a) The Borrower will not, and will not permit any Restricted Subsidiaries to, prior to the date that is ninety-one (91) days after the Maturity Date: (i) call, make or offer to

make any optional or voluntary Redemption of or otherwise optionally or voluntarily Redeem (whether in whole or in part) the Existing Senior Notes (other than Redemption of the Existing Senior Notes Due 2017 on the scheduled maturity date thereof) or the Senior Notes; provided that the Borrower may prepay or otherwise Redeem the Existing Senior Notes or Senior Notes in whole or in part with the net cash proceeds of (A) any sale of Equity Interests (other than Disqualified Capital Stock) of the Borrower, (B) any Permitted Refinancing of the Existing Senior Notes or Senior Notes or (C) any combination thereof, (ii) amend, modify, waive or otherwise change, consent or agree to any amendment, modification, waiver or other change to, any of the terms of the Existing Senior Notes, the Existing Indenture, the Senior Notes or the Senior Notes Indenture if the effect thereof would be to shorten its maturity or average life or increase the amount of any payment of principal thereof or increase the rate or shorten any period for payment of interest thereon or (iii) with respect to Senior Notes that are subordinated to the Indebtedness or any other Debt, designate any Debt (other than obligations of the Borrower and the Credit Parties pursuant to the Loan Documents) as “designated senior debt” or “designated guarantor senior debt” or give any such other Debt any other similar designation for the purposes of any Indenture related to Senior Notes that are subordinated to the Indebtedness or any other Debt.

(b) The Borrower will not, and will not permit any Restricted Subsidiaries to, call, make or offer to make any Redemption of (whether in whole or in part) any Permitted Unrestricted Subsidiary Debt unless (i) no Default or Event of Default then exists or would result therefrom, (ii) no Borrowing Base Deficiency then exists and (iii) Liquidity is not less than 10% of the then effective Loan Limit (on a pro forma basis after giving effect to such Redemption).

Section 9.20 Use of Loans and Letters of Credit. The Borrower will not request any Borrowing or Letter of Credit, and the Borrower shall not use, and shall ensure that its Subsidiaries and its or their respective directors, officers, employees and agents shall not use, the proceeds of any Borrowing or Letter of Credit (a) in furtherance of an offer, payment, promise to pay, or authorization of the payment or giving of money, or anything else of value, to any Person in violation of any Anti-Corruption Laws, (b) for the purpose of funding, financing or facilitating any activities, business or transaction of or with any Sanctioned Person, or in any Sanctioned Country or (c) in any manner that would result in the violation of any Sanctions applicable to any party hereto.

Section 10.02 Remedies.

(a) In the case of an Event of Default other than one described in Section 10.01(h), Section 10.01(i) or Section 10.01(j), at any time thereafter during the continuance of such Event of Default, the Administrative Agent may, and at the request of the Required Lenders, shall, by notice to the Borrower, take either or both of the following actions, at the same or different times: (i) terminate the Commitments, and thereupon the Commitments shall terminate immediately, and (ii) declare the Notes and the Loans then outstanding to be due

114

and payable in whole (or in part, in which case any principal not so declared to be due and payable may thereafter be declared to be due and payable), and thereupon the principal of the Loans so declared to be due and payable, together with accrued interest thereon and all fees and other obligations of the Borrower and the Guarantors accrued hereunder and under the Notes and the other Loan Documents (including the payment of cash collateral to secure the LC Exposure as provided in Section 2.08(j)), shall become due and payable immediately, without presentment, demand, protest, notice of intent to accelerate, notice of acceleration or other notice of any kind, all of which are hereby waived by the Borrower and each Guarantor; and in case of an Event of Default described in Section 10.01(h), Section 10.01(i) or Section 10.01(j), the Commitments shall automatically terminate and the Notes and the principal of the Loans then outstanding, together with accrued interest thereon and all fees and the other obligations of the Borrower and the Guarantors accrued hereunder and under the Notes and the other Loan Documents (including the payment of cash collateral to secure the LC Exposure as provided in Section 2.08(j)), shall automatically become due and payable, without presentment, demand, protest or other notice of any kind, all of which are hereby waived by the Borrower and each Guarantor.

(b) In the case of the occurrence of an Event of Default, the Administrative Agent and the Lenders will have all other rights and remedies available at law and equity. The Borrower, the Administrative Agent and each Secured Party hereby agree that, except as expressly set forth in the Loan Documents, no Secured Party shall have any right individually to realize upon any collateral granted to or held by the Administrative Agent for the benefit of the Secured Parties under the Loan Documents or to enforce the Guaranty Agreement (it being understood and agreed that, except as expressly set forth in the Loan Documents, all powers, rights and remedies hereunder may be exercised solely by the Administrative Agent on behalf of the Secured Parties in accordance with the terms hereof and all powers, rights and remedies under the Security Instruments may be exercised solely by the Administrative Agent). Nothing in this paragraph shall preclude any Secured Party from (i) exercising any rights of setoff granted to it pursuant to the Loan Documents or (ii) making or filing claims in any bankruptcy or insolvency proceeding to the extent it is legally entitled to do so.

(c) All proceeds realized from the liquidation or other disposition of collateral or otherwise received after maturity of the Loans, whether by acceleration or otherwise, shall be applied:

(i) first, to payment or reimbursement of that portion of the Indebtedness constituting fees, expenses and indemnities payable to the Administrative Agent in its capacity as such, the Issuing Bank in its capacity as such and the Swingline Lender in its capacity as such, ratably among them in proportion to the respective amounts described in this clause payable to them;

115

Borrower at such time, (C) cash collateral to be held by the Administrative Agent to secure the remaining LC Exposure and (D) Indebtedness under Secured Swap Agreements owing to each Secured Swap Provider;

Notwithstanding the foregoing, amounts received from the Borrower or any Guarantor that is not an “eligible contract participant” under the Commodity Exchange Act shall not be applied to any Excluded Swap Obligations (it being understood, that in the event that any amount is applied to Indebtedness other than Excluded Swap Obligations as a result of this clause, the Administrative Agent shall make such adjustments as it determines are appropriate to distributions pursuant to clause fourth above from amounts received from “eligible contract participants” under the Commodity Exchange Act to ensure, as nearly as possible, that the proportional aggregate recoveries with respect to Indebtedness described in clause fourth above by the holders of any Excluded Swap Obligations are the same as the proportional aggregate recoveries with respect to other Indebtedness pursuant to clause fourth above).

ARTICLE XI

THE AGENTS

Section 11.01 Appointment; Powers. 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 and the other Loan Documents, together with such actions and powers as are reasonably incidental thereto.

Section 11.02 Duties and Obligations of Administrative Agent. The Administrative Agent shall not have any duties or obligations except those expressly set forth in the Loan Documents. 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 (the use of the term “agent” herein and in the other Loan Documents with reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law; rather, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties), (b) the Administrative Agent shall have no duty to take any discretionary action or exercise any discretionary powers, except as provided in Section 11.03, 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 the Borrower or any of its Subsidiaries 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 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 shall not be responsible for or have any duty to ascertain or inquire

116

into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other document delivered hereunder or under any other Loan Document or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or in any other Loan Document, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document, (v) the satisfaction of any condition set forth in Article VI or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent or as to those conditions precedent expressly required to be to the Administrative Agent’s satisfaction, (vi) the existence, value, perfection or priority of any collateral security or the financial or other condition of the Borrower and its Subsidiaries or any other obligor or guarantor, or (vii) any failure by the Borrower or any other Person (other than itself) to perform any of its obligations hereunder or under any other Loan Document or the performance or observance of any covenants, agreements or other terms or conditions set forth herein or therein. For purposes of determining compliance with the conditions specified in Article VI, each Lender shall be deemed to have consented to, approved or accepted or to be satisfied with, each document or other matter required thereunder to be consented to or approved by or acceptable or satisfactory to a Lender unless the Administrative Agent shall have received written notice from such Lender prior to the effectiveness of this Agreement specifying its objection thereto.

Section 11.03 Action by Administrative Agent. The Administrative Agent shall have no duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that the Administrative Agent is required to exercise in writing as directed by the Majority Lenders (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 12.02) and in all cases the Administrative Agent shall be fully justified in failing or refusing to act hereunder or under any other Loan Documents unless it shall (a) receive written instructions from the Majority Lenders, the Required Lenders or each Lender, as applicable (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 12.02), specifying the action to be taken and (b) be indemnified to its satisfaction by the Lenders against any and all liability and expenses which may be incurred by it by reason of taking or continuing to take any such action. The instructions as aforesaid and any action taken or failure to act pursuant thereto by the Administrative Agent shall be binding on all of the Lenders. If a Default has occurred and is continuing, then the Administrative Agent shall take such action with respect to such Default as shall be directed by the requisite Lenders in the written instructions (with indemnities) described in this Section 11.03, provided that, unless and until the Administrative Agent shall have received such directions, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default as it shall deem advisable in the best interests of the Lenders. In no event, however, shall the Administrative Agent be required to take any action which exposes the Administrative Agent to personal liability or which is contrary to this Agreement, the Loan Documents or applicable law. If a Default has occurred and is continuing, neither the Syndication Agent nor the Co-Documentation Agents shall have any obligation to perform any act in respect thereof. 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, the Required Lenders or each Lender, as applicable (or such other number or percentage of the

117

Lenders as shall be necessary under the circumstances as provided in Section 12.02), and otherwise the Administrative Agent shall not be liable for any action taken or not taken by it hereunder or under any other Loan Document or under any other document or instrument referred to or provided for herein or therein or in connection herewith or therewith INCLUDING ITS OWN ORDINARY NEGLIGENCE, except for its own gross negligence or willful misconduct.

Section 11.04 Reliance by Administrative Agent. 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 and each of the Borrower, the Lenders and the Issuing Bank hereby waives the right to dispute the Administrative Agent’s record of such statement, except in the case of gross negligence or willful misconduct by the Administrative Agent. 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 deem and treat the payee of any Note as the holder thereof for all purposes hereof unless and until a written notice of the assignment or transfer thereof permitted hereunder shall have been filed with the Administrative Agent.

Section 11.05 Subagents. 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 Sections of this Article XI 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.

Section 11.06 Resignation or Removal of Administrative Agent. Subject to the appointment and acceptance of a successor Administrative Agent as provided in this Section 11.06, the Administrative Agent may resign at any time by notifying the Lenders, the Issuing Bank and the Borrower, and the Administrative Agent may be removed by Majority Lenders if the Administrative Agent in its capacity as a Lender is a Defaulting Lender pursuant to clause (d) of the definition thereof. Upon any such resignation or removal, the Majority Lenders shall have the right, in consultation with and upon the approval of the Borrower (so long as no Event of Default has occurred and is continuing), to appoint a successor Administrative Agent. If no successor shall have been so appointed by the Majority Lenders and shall have accepted such appointment within thirty (30) days after the retiring Administrative Agent gives notice of its resignation or the removal of the removed Administrative Agent, then the retiring or removed 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 New York, New York, or an Affiliate of any such bank; provided that in no event shall any such successor Administrative Agent be a Defaulting Lender or an Affiliate of a Defaulting Lender. Upon the acceptance of its

118

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 or removed Administrative Agent, and the retiring or removed 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 or removal hereunder, the provisions of this Article XI and Section 12.03 shall continue in effect for the benefit of such retiring or removed 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. Any resignation by Wells Fargo as Administrative Agent pursuant to this Section shall also constitute its resignation as Issuing Bank and Swingline Lender.

Section 11.07 Agents as Lenders. Each bank serving as an 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 an Agent, and such bank and its Affiliates may accept deposits from, lend money to and generally engage in any kind of business with the Borrower or any Subsidiary or other Affiliate thereof as if it were not an Agent hereunder.

Section 11.08 No Reliance. Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent, any other 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 and each other Loan Document to which it is a party. Each Lender also acknowledges that it will, independently and without reliance upon the Administrative Agent, any other 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 other Loan Document, any related agreement or any document furnished hereunder or thereunder. The Agents shall not be required to keep themselves informed as to the performance or observance by the Borrower or any of its Subsidiaries of this Agreement, the Loan Documents or any other document referred to or provided for herein or to inspect the Properties or books of the Borrower or its Subsidiaries. Except for notices, reports and other documents and information expressly required to be furnished to the Lenders by the Administrative Agent hereunder, no Agent or the Arrangers shall have any duty or responsibility to provide any Lender with any credit or other information concerning the affairs, financial condition or business of the Borrower (or any of its Affiliates) which may come into the possession of such Agent or any of its Affiliates. In this regard, each Lender acknowledges that Vinson & Elkins L.L.P. is acting in this transaction as special counsel to the Administrative Agent only, except to the extent otherwise expressly stated in any legal opinion or any Loan Document. Each other party hereto will consult with its own legal counsel to the extent that it deems necessary in connection with the Loan Documents and the matters contemplated therein.

119

Section 11.09 Administrative Agent May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Borrower or any of its Subsidiaries, the Administrative Agent (irrespective of whether the principal of any Loan shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent shall have made any demand on the Borrower) shall be entitled and empowered, by intervention in such proceeding or otherwise:

(a) to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans and all other Indebtedness that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Lenders and the Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders and the Administrative Agent and their respective agents and counsel and all other amounts due the Lenders and the Administrative Agent under Section 12.03) allowed in such judicial proceeding; and

(b) to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender to make such payments to the Administrative Agent and, in the event that the Administrative Agent shall consent to the making of such payments directly to the Lenders, to pay to the Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Administrative Agent and its agents and counsel, and any other amounts due the Administrative Agent under Section 12.03.

Nothing contained herein shall be deemed to authorize the Administrative Agent to authorize or consent to or accept or adopt on behalf of any Lender any plan of reorganization, arrangement, adjustment or composition affecting the Indebtedness or the rights of any Lender or to authorize the Administrative Agent to vote in respect of the claim of any Lender in any such proceeding.

Section 11.10 Authority of Administrative Agent to Release Collateral, Liens and Guarantors; Assignment of Swap Agreements. Each Lender and the Issuing Bank hereby authorizes the Administrative Agent to take the following actions (all without further consent or joinder of, or notice to, any Lender or any other Secured Party) and the Administrative Agent hereby agrees to take such actions at the request of the Borrower: (a) to release any Lien on any collateral or other property granted to or held by the Administrative Agent under any Loan Document (i) as provided for by such Loan Document, (ii) that is sold, released or otherwise disposed of as permitted pursuant to the terms of the Loan Documents (including any collateral owned by a Restricted Subsidiary that is designated as an Unrestricted Subsidiary in accordance with Section 9.06(b) or as permitted by Section 9.12), (iii) to the extent such collateral is comprised of property leased to a Credit Party, upon termination or expiration of such lease, (iv) if approved, authorized or ratified in writing by the Majority Lenders (or, if such approval, authorization or ratification by all Lenders is required under Section 12.02(b), then by all Lenders), and (v) to the extent such collateral is owned by any Guarantor, upon the release of such Guarantor in accordance with the following clause or the Guaranty Agreement; (b) to release any Guarantor if 100% of the Equity Interests in such Guarantor are sold in a transaction permitted under the Loan Documents, if such Guarantor ceases to be a Material Subsidiary, or if such Guarantor ceases to be a Restricted Subsidiary as a result of a transaction permitted under the Loan Documents; (c) to release all Liens on the collateral and other property and all obligations under any Security Instruments (i) upon the Borrower’s election to enter into an

120

Investment Grade Period pursuant to Section 12.18 and the Administrative Agent’s receipt of the written notice contemplated therein (but excluding the Guaranty Agreement, which shall not be released upon the Borrower’s election to enter into an Investment Grade Period) or (ii) upon termination of all Commitments and payment in full of all Indebtedness (other than any contingent obligations or indemnification obligations not then due) and the expiration or termination of all Letters of Credit (other than Letters of Credit that have been cash collateralized in manner satisfactory to the Administrative Agent and the Issuing Bank have been made); (d) to subordinate (or release) any Lien on any collateral or other property granted to or held by the Administrative Agent under any Loan Document to any Lien on such property that is permitted by Section 9.03(c); and (e) 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 necessary, useful or otherwise reasonably requested by the Borrower to accomplish or evidence the foregoing. By accepting the benefit of the Liens granted pursuant to the Security Instruments, each Person secured by such Liens that is not a party hereto agrees to the terms of this Section 11.10 . Each Lender hereby agrees (on behalf of itself and any of its Affiliates party to any Secured Swap Agreement) that the rights of the Borrower and the Restricted Subsidiaries under Secured Swap Agreements with such Secured Swap Provider may be included in the collateral granted to or held by the Administrative Agent under the Loan Documents.

Section 11.11 The Arrangers, the Syndication Agent and the Co-Documentation Agents. The Arrangers, the Syndication Agent and the Co-Documentation Agents shall have no duties, responsibilities or liabilities under this Agreement and the other Loan Documents other than their duties, responsibilities and liabilities in their capacity as Lenders hereunder.

122

123

Agreement or any other Loan Document without the consent of the Lenders in order to correct, amend or cure any ambiguity, inconsistency or defect or correct any typographical error or other manifest error in any Loan Document, and (z) the Administrative Agent and the Borrower (or other applicable Credit Party) may enter into any amendment, modification or waiver of this Agreement or any other Loan Document or enter into any agreement or instrument to effect the granting, perfection, protection, expansion or enhancement of any security interest in any Mortgaged Property or Property to become Mortgaged Property to secure the Indebtedness for the benefit of the Lenders or as required by any Governmental Requirement to give effect to, protect or otherwise enhance the rights or benefits of any Lender under the Loan Documents without the consent of any Lender.

(iii) Subject to Section 12.04(b)(iv) and the acceptance and recording thereof, from and after the effective date specified in each Assignment and Assumption the assignee thereunder shall be a party hereto and, to the extent of the 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 5.01, Section 5.02, Section 5.03 and Section 12.03) with respect to facts and circumstances occurring prior to the effective date of such assignment; provided, that except to the extent otherwise expressly agreed by the affected parties, no such assignment by a Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender having been a Defaulting Lender. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 12.04 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 Section 12.04(c).

(iv) The Administrative Agent, acting solely for this purpose as a non-fiduciary agent of the Borrower, shall maintain at one of its offices in the United States of America 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 Commitments of, and principal amount (and stated interest) 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 absent manifest error, and the Borrower, the Administrative Agent, the Swingline Lender, 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 Borrower, the Swingline Lender, the Issuing Bank and any Lender, at any reasonable time and from time to time upon reasonable prior notice. In connection with any changes to the Register, if necessary, the Administrative Agent will reflect the revisions on Annex I and forward a copy of such revised Annex I to the Borrower, the Issuing Bank and each Lender.

(v) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an assignee, the assignee’s completed

129

Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in Section 12.04(b) (unless waived by the Administrative Agent) and any written consent to such assignment required by Section 12.04(b), the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the Register. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this Section 12.04(b).

(vi) In connection with any assignment of rights and obligations of any Defaulting Lender hereunder, no such assignment shall be effective unless and until, in addition to the other conditions thereto set forth herein, the parties to the assignment shall make such additional payments to the Administrative Agent in an aggregate amount sufficient, upon distribution thereof as appropriate (which may be outright payment, purchases by the assignee of participations or subparticipations, or other compensating actions, including funding, with the consent of the Borrower and the Administrative Agent, the applicable pro rata share of Loans previously requested but not funded by the Defaulting Lender, to each of which the applicable assignee and assignor hereby irrevocably consent), to (x) pay and satisfy in full all payment liabilities then owed by such Defaulting Lender to the Administrative Agent, the Issuing Bank, the Swingline Lender and each other Lender hereunder (and interest accrued thereon), and (y) acquire (and fund as appropriate) its full pro rata share of all Loans and participations in Letters of Credit and Swingline Loans in accordance with its Applicable Percentage. Notwithstanding the foregoing, in the event that any assignment of rights and obligations of any Defaulting Lender hereunder shall become effective under applicable law without compliance with the provisions of this paragraph, then the assignee of such interest shall be deemed to be a Defaulting Lender for all purposes of this Agreement until such compliance occurs.

(c)(i) Any Lender may, without the consent of the Borrower, the Administrative Agent, the Swingline Lender or the Issuing Bank, sell participations to one or more banks or other Persons (other than the Borrower, any Affiliate of the Borrower, any Defaulting Lender or subsidiary of a Defaulting Lender or any natural person) (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); 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 Swingline Lender, 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 proviso to Section 12.02(b) that adversely affects such Participant. In addition such agreement must provide that the Participant be bound by the provisions of Section 12.03. Subject to Section 12.04(c)(ii), the Borrower agrees that each Participant shall be entitled to the benefits of Section 5.01, Section 5.02 and Section 5.03 (subject to the

130

requirements and limitations therein, including the requirements under Sections 5.03(f) and 5.03(g) (it being understood that the documentation required under Sections 5.03(f) and 5.03(g) shall be delivered to the Lender who sells the participation)) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to Section 12.04(b). To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 12.08 as though it were a Lender, provided such Participant agrees to be subject to Section 4.01(c) as though it were a Lender. Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Loans or other obligations under the Loan Documents (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant’s interest in any commitments, loans, letters of credit or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such commitment, loan, letter of credit or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrative Agent (in its capacity as Administrative Agent) shall have no responsibility for maintaining a Participant Register.

(ii) Each Participant agrees (A) to be subject to the provisions of Section 5.04 as if it were an assignee under paragraph (b) of this Section; and (B) that it shall not be entitled to receive any greater payment under Section 5.01 or Section 5.03, with respect to any participation, than its participating Lender would have been entitled to receive, except to the extent such entitlement to receive a greater payment results from a Change in Law that occurs after the Participant acquired the applicable participation. Each Lender that sells a participation agrees, at the Borrower’s request and expense, to use commercially reasonable efforts to cooperate with the Borrower to effectuate the provisions of Section 5.04 with respect to any Participant.

(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 any pledge or assignment to secure obligations to a Federal Reserve Bank or other central bank having jurisdiction over such Lender, and this Section 12.04 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.

(e) Notwithstanding any other provisions of this Section 12.04, no transfer or assignment of the interests or obligations of any Lender or any grant of participations therein shall be permitted if such transfer, assignment or grant would require the Borrower and the Guarantors to file a registration statement with the SEC or to qualify the Loans under the “Blue Sky” laws of any state.

131

Section 12.05 Survival; Revival; Reinstatement.

(a) All covenants, agreements, representations and warranties made by the Borrower herein and in the certificates or other instruments delivered in connection with or pursuant to this Agreement or any other Loan Document 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, any other 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 Commitments have not expired or terminated. The provisions of Section 5.01, Section 5.02, Section 5.03 and Section 12.03 and Article XI shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Letters of Credit and the Commitments or the termination of this Agreement, any other Loan Document or any provision hereof or thereof.

(b) To the extent that any payments on the Indebtedness or proceeds of any collateral are subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be repaid to a trustee, debtor in possession, receiver or other Person under any bankruptcy law, common law or equitable cause, then to such extent, the Indebtedness so satisfied shall be revived and continue as if such payment or proceeds had not been received and the Administrative Agent’s and the Lenders’ Liens, security interests, rights, powers and remedies under this Agreement and each Loan Document shall continue in full force and effect. In such event, each Loan Document shall be automatically reinstated and the Borrower shall take such action as may be reasonably requested by the Administrative Agent and the Lenders to effect such reinstatement.

Section 12.06 Counterparts; Integration; Effectiveness.

(a) 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.

(b) This Agreement, the other Loan Documents and any separate letter agreements with respect to fees payable to the Administrative Agent constitute the entire contract among the parties relating to the subject matter hereof and thereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof and thereof. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT AMONG THE PARTIES HERETO AND THERETO 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.

132

(c) Except as provided in Section 6.01, 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 fax or other electronic transmission (e.g., via email in .pdf format) shall be effective as delivery of a manually executed counterpart of this Agreement.

Section 12.07 Severability. Any provision of this Agreement or any other Loan Document 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 or thereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

Section 12.08 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 (of whatsoever kind, including, without limitations obligations under Swap Agreements) at any time owing by such Lender or Affiliate (but excluding any Plan accounts and assets and any other account for which setoff would be prohibited by applicable law) to or for the credit or the account of the Borrower or any Restricted Subsidiary against any of and all the obligations of the Borrower or any Restricted Subsidiary owed to such Lender now or hereafter existing under this Agreement or any other Loan Document, irrespective of whether or not such Lender shall have made any demand under this Agreement or any other Loan Document and although such obligations may be unmatured. The rights of each Lender under this Section 12.08 are in addition to other rights and remedies (including other rights of setoff) which such Lender or its Affiliates may have. Each Lender agrees to notify the Borrower and the Administrative Agent promptly after any such setoff and application.

Section 12.09 GOVERNING LAW; JURISDICTION; CONSENT TO SERVICE OF PROCESS.

(a) THIS AGREEMENT AND THE NOTES SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK EXCEPT TO THE EXTENT THAT UNITED STATES FEDERAL LAW PERMITS ANY LENDER TO CONTRACT FOR, CHARGE, RECEIVE, RESERVE OR TAKE INTEREST AT THE RATE ALLOWED BY THE LAWS OF THE STATE WHERE SUCH LENDER IS LOCATED.

(b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THE LOAN DOCUMENTS MAY BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK OR OF THE UNITED STATES OF AMERICA FOR THE SOUTHERN DISTRICT OF NEW YORK, IN EITHER CASE LOCATED IN NEW YORK COUNTY, NEW YORK, AND, BY EXECUTION AND DELIVERY OF THIS AGREEMENT, EACH PARTY HEREBY

133

ACCEPTS FOR ITSELF AND (TO THE EXTENT PERMITTED BY LAW) IN RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, THE JURISDICTION OF THE AFORESAID COURTS. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY SUCH ACTION OR PROCEEDING IN SUCH RESPECTIVE JURISDICTIONS. THIS SUBMISSION TO JURISDICTION IS NON-EXCLUSIVE AND DOES NOT PRECLUDE A PARTY FROM OBTAINING JURISDICTION OVER ANOTHER PARTY IN ANY COURT OTHERWISE HAVING JURISDICTION.

(c) EACH PARTY IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OF ANY OF THE AFOREMENTIONED COURTS IN ANY SUCH ACTION OR PROCEEDING BY THE MAILING OF COPIES THEREOF BY REGISTERED OR CERTIFIED MAIL, POSTAGE PREPAID, TO IT AT THE ADDRESS SPECIFIED IN SECTION 12.01 OR SUCH OTHER ADDRESS AS IS SPECIFIED PURSUANT TO SECTION 12.01 (OR ITS ASSIGNMENT AND ASSUMPTION), SUCH SERVICE TO BECOME EFFECTIVE THIRTY (30) DAYS AFTER SUCH MAILING. NOTHING HEREIN SHALL AFFECT THE RIGHT OF A PARTY OR ANY HOLDER OF A NOTE TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR TO COMMENCE LEGAL PROCEEDINGS OR OTHERWISE PROCEED AGAINST ANOTHER PARTY IN ANY OTHER JURISDICTION.

(d) EACH PARTY HEREBY (i) IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN; (ii) IRREVOCABLY WAIVES, TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY SUCH LITIGATION ANY SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES, OR DAMAGES OTHER THAN, OR IN ADDITION TO, ACTUAL DAMAGES; (iii) CERTIFIES THAT NO PARTY HERETO NOR ANY REPRESENTATIVE OR AGENT OR COUNSEL FOR ANY PARTY HERETO HAS REPRESENTED, EXPRESSLY OR OTHERWISE, OR IMPLIED THAT SUCH PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVERS, AND (iv) ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT, THE LOAN DOCUMENTS AND THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS CONTAINED IN THIS SECTION 12.09.

Section 12.10 Headings. Article and Section headings and the Table of Contents used herein are for convenience of reference only, are not part of this Agreement and shall not affect the construction of, or be taken into consideration in interpreting, this Agreement.

Section 12.11 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

134

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 required or requested by any regulatory authority purporting to have jurisdiction over such Person, (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 or any other Loan Document, (e) in connection with the exercise of any remedies hereunder or under any other Loan Document or any suit, action or proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section 12.11, 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 any Person invited to become an Additional Lender pursuant to Section 2.10 or (ii) any actual or prospective counterparty (or its advisors) to any Swap Agreement relating to the Borrower and its obligations, (g) on a confidential basis to (A) any rating agency in connection with rating the Borrower or its Subsidiaries or the credit facilities provided hereunder or (B) the CUSIP Service Bureau or any similar agency in connection with the issuance and monitoring of CUSIP numbers or other market identifiers with respect to the credit facilities provided hereunder, (h) with the consent of the Borrower or (i) to the extent such Information (1) becomes publicly available other than, to such Person’s knowledge, as a result of a breach of this Section 12.11 or (2) becomes available to the Administrative Agent, the Issuing Bank or any Lender on a nonconfidential basis from a source other than the Borrower that is not, to such Person’s knowledge, violating the terms of any applicable confidentiality agreement or arrangement. For the purposes of this Section 12.11, “Information” means all information received from a Credit Party or Subsidiary relating to the Credit Parties or any Subsidiary or any of their respective businesses (which includes all information obtained during an inspection conducted under Section 8.07), 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 a Credit Party or any Subsidiary. Any Person required to maintain the confidentiality of Information as provided in this Section 12.11 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. Each of the Administrative Agent, the Issuing Bank and the Lenders acknowledges that (a) the Information may include material non-public information concerning a Credit Party or a Subsidiary, as the case may be, (b) it has developed compliance procedures regarding the use and protection of material non-public information and (c) it will handle such material non-public information in accordance with applicable Law, including United States federal and state securities Laws.

Section 12.12 Interest Rate Limitation. It is the intention of the parties hereto that each Lender shall conform strictly to usury laws applicable to it. Accordingly, if the transactions contemplated hereby would be usurious as to any Lender under laws applicable to it (including the laws of the United States of America, the State of New York and the State of Texas or any other jurisdiction whose laws may be mandatorily applicable to such Lender notwithstanding the other provisions of this Agreement), then, in that event, notwithstanding anything to the contrary in any of the Loan Documents or any agreement entered into in connection with or as security for the Notes, it is agreed as follows: (i) the aggregate of all consideration which constitutes interest under law applicable to any Lender that is contracted for, taken, reserved, charged or received by such Lender under any of the Loan Documents or agreements or otherwise in connection with the Notes shall under no circumstances exceed the maximum amount allowed

135

by such applicable law, and any excess shall be canceled automatically and if theretofore paid shall be credited by such Lender on the principal amount of the Indebtedness (or, to the extent that the principal amount of the Indebtedness shall have been or would thereby be paid in full, refunded by such Lender to the Borrower); and (ii) in the event that the maturity of the Notes is accelerated by reason of an election of the holder thereof resulting from any Event of Default under this Agreement or otherwise, or in the event of any required or permitted prepayment, then such consideration that constitutes interest under law applicable to any Lender may never include more than the maximum amount allowed by such applicable law, and excess interest, if any, provided for in this Agreement or otherwise shall be canceled automatically by such Lender as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited by such Lender on the principal amount of the Indebtedness (or, to the extent that the principal amount of the Indebtedness shall have been or would thereby be paid in full, refunded by such Lender to the Borrower). All sums paid or agreed to be paid to any Lender for the use, forbearance or detention of sums due hereunder shall, to the extent permitted by law applicable to such Lender, be amortized, prorated, allocated and spread throughout the stated term of the Loans evidenced by the Notes until payment in full so that the rate or amount of interest on account of any Loans hereunder does not exceed the maximum amount allowed by such applicable law. If at any time and from time to time (i) the amount of interest payable to any Lender on any date shall be computed at the Highest Lawful Rate applicable to such Lender pursuant to this Section 12.12 and (ii) in respect of any subsequent interest computation period the amount of interest otherwise payable to such Lender would be less than the amount of interest payable to such Lender computed at the Highest Lawful Rate applicable to such Lender, then the amount of interest payable to such Lender in respect of such subsequent interest computation period shall continue to be computed at the Highest Lawful Rate applicable to such Lender until the total amount of interest payable to such Lender shall equal the total amount of interest which would have been payable to such Lender if the total amount of interest had been computed without giving effect to this Section 12.12. To the extent that Chapter 303 of the Texas Finance Code is relevant for the purpose of determining the Highest Lawful Rate applicable to a Lender, such Lender elects to determine the applicable rate ceiling under such Chapter by the weekly ceiling from time to time in effect. Chapter 346 of the Texas Finance Code does not apply to the Borrower’s obligations hereunder.

Section 12.13 EXCULPATION PROVISIONS. EACH OF THE PARTIES HERETO SPECIFICALLY AGREES THAT IT HAS A DUTY TO READ THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS AND AGREES THAT IT IS CHARGED WITH NOTICE AND KNOWLEDGE OF THE TERMS OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; THAT IT HAS IN FACT READ THIS AGREEMENT AND IS FULLY INFORMED AND HAS FULL NOTICE AND KNOWLEDGE OF THE TERMS, CONDITIONS AND EFFECTS OF THIS AGREEMENT; THAT IT HAS BEEN REPRESENTED BY INDEPENDENT LEGAL COUNSEL OF ITS CHOICE THROUGHOUT THE NEGOTIATIONS PRECEDING ITS EXECUTION OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; AND HAS RECEIVED THE ADVICE OF ITS ATTORNEY IN ENTERING INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; AND THAT IT RECOGNIZES THAT CERTAIN OF THE TERMS OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS RESULT IN ONE PARTY ASSUMING THE LIABILITY INHERENT IN SOME ASPECTS OF THE TRANSACTION AND RELIEVING THE OTHER PARTY OF ITS RESPONSIBILITY FOR SUCH LIABILITY. EACH PARTY

136

HERETO AGREES AND COVENANTS THAT IT WILL NOT CONTEST THE VALIDITY OR ENFORCEABILITY OF ANY EXCULPATORY PROVISION OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS ON THE BASIS THAT THE PARTY HAD NO NOTICE OR KNOWLEDGE OF SUCH PROVISION OR THAT THE PROVISION IS NOT “CONSPICUOUS.”

Section 12.14 Collateral Matters; Swap Agreements; Bank Products. The benefit of the Security Instruments and of the provisions of this Agreement relating to any collateral securing the Indebtedness shall also extend to and be available to the Secured Swap Providers with respect to any Secured Swap Agreement (in each case, after giving effect to all netting arrangements relating to such Secured Swap Agreement) including any Secured Swap Agreement in existence prior to the date hereof, but excluding any additional transactions or confirmations entered into (a) after such Secured Swap Provider ceases to be a Lender or an Affiliate of a Lender or (b) after assignment by a Secured Swap Provider to a Person that is not a Lender or an Affiliate of a Lender. The benefit of the Security Instruments and of the provisions of this Agreement relating to any collateral securing the Indebtedness shall further extend to and be available to each Bank Products Provider with respect to any Secured Bank Products Agreements, but only for so long as such Bank Products Provider is a Lender or an Affiliate of a Lender. No Person shall have any voting or consent rights under any Loan Document as a result of the existence of obligations owed to it under any such Secured Swap Agreements or any such Secured Bank Products Agreements.

Section 12.15 No Third Party Beneficiaries. This Agreement, the other Loan Documents, and the agreement of the Lenders to make Loans and the Issuing Bank to issue, amend, renew or extend Letters of Credit hereunder are solely for the benefit of the Borrower, and no other Person (including any Subsidiary of the Borrower, any obligor, contractor, subcontractor, supplier or materialsman) shall have any rights, claims, remedies or privileges hereunder or under any other Loan Document against the Administrative Agent, any other Agent, the Issuing Bank or any Lender for any reason whatsoever. There are no third party beneficiaries.

Section 12.16 USA Patriot Act Notice. Each Lender hereby notifies the Borrower that pursuant to the requirements of the Patriot Act, it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Lender to identify the Borrower in accordance with the Patriot Act.

Section 12.17 No Advisory or Fiduciary Responsibility. In connection with all aspects of each transaction contemplated hereby (including in connection with any amendment, waiver or other modification hereof or of any other Loan Document), the Borrower acknowledges and agrees, and acknowledges its Subsidiaries’ understanding, that: (a) (i) no fiduciary, advisory or agency relationship (except solely with respect to the Administrative Agent or the applicable Lender maintaining a Register or Participant Register, as applicable, as expressly provided in Section 12.04) between the Borrower and its Subsidiaries and the Administrative Agent or any Lender is intended to be or has been created in respect of the transactions contemplated hereby or by the other Loan Documents, irrespective of whether the Administrative Agent or any Lender has advised or is advising the Borrower or any Subsidiary on other matters; (ii) the arranging and

137

other services regarding this Agreement provided by the Administrative Agent and the Lenders are arm’s-length commercial transactions between the Borrower and its Subsidiaries, on the one hand, and the Administrative Agent and the Lenders, on the other hand; (iii) the Borrower has consulted its own legal, accounting, regulatory and tax advisors to the extent that it has deemed appropriate; and (iv) the Borrower is capable of evaluating, and understands and accepts, the terms, risks and conditions of the transactions contemplated hereby and by the other Loan Documents; and (b) (i) the Administrative Agent and the Lenders each is and has been acting solely as a principal and, except as expressly agreed in writing by the relevant parties, has not been, is not, and will not be acting as an advisor, agent or fiduciary for the Borrower or any of its Subsidiaries, or any other Person; (ii) neither the Administrative Agent nor the Lenders has any obligation to the Borrower or any of its Subsidiaries with respect to the transactions contemplated hereby except those obligations expressly set forth herein and in the other Loan Documents; and (iii) the Administrative Agent and the Lenders and their respective Affiliates may be engaged, for their own accounts or the accounts of customers, in a broad range of transactions that involve interests that differ from those of the Borrower and its Subsidiaries, and neither the Administrative Agent nor the Lenders has any obligation to disclose any of such interests to the Borrower or its Subsidiaries. To the fullest extent permitted by Law, the Borrower hereby waives and releases any claims that it may have against the Administrative Agent and the Lenders with respect to any breach or alleged breach of agency or fiduciary duty in connection with any aspect of any transaction contemplated hereby.

Section 12.18 Investment Grade Period.

(a) At any time that is not an Investment Grade Period after the date on which the Borrower delivers the financial statements required by Section 8.01(a) for the fiscal year ending December 31, 2014 when the Borrower has either (i) an unsecured rating from Moody’s of Baa3 or better or (ii) an unsecured rating from S&P of BBB- or better, the Borrower may provide written notice to the Administrative Agent of its election to enter into an Investment Grade Period, together with a certificate of an Responsible Officer of the Borrower confirming that (A) no Event of Default exists, (B) the release of the Security Instruments (other than the Guaranty Agreement) securing the Indebtedness does not violate, and would not result in an event of default, termination event or equivalent event under, the terms of any Secured Swap Agreement or Secured Bank Products Agreement, and (C) the Swap Agreements (including the Secured Swap Agreements) and the Bank Products (including any Secured Bank Products Agreements) of the Borrower and its Restricted Subsidiaries are not otherwise secured (except to the extent secured by a Lien permitted by Section 9.03), which Investment Grade Period will commence upon the Administrative Agent’s receipt of such notice.

(b) At any time during an Investment Grade Period, the Borrower may provide notice to the Administrative Agent of its election to exit such Investment Grade Period, which Investment Grade Period will end upon the Administrative Agent’s receipt of such notice.

SCHEDULE 7.05

LITIGATION

See items disclosed in Schedule 7.06 to this Agreement.

Items disclosed or referenced in this Schedule are not necessarily limited to matters required by this Agreement to be reflected herein. Such additional matters not required by this Agreement are set forth for informational purposes only and do not necessarily include other matters of a similar nature. The mere inclusion of an exception herein shall not be deemed an admission by the Borrower or any of its Subsidiaries that such exception represents a matter that is material for purposes of this Agreement, is necessarily expected to have a Material Adverse Effect or is required to be disclosed herein. Nothing herein shall constitute an admission to any third party.

SCHEDULE 7.05 – 1

SCHEDULE 7.06

ENVIRONMENTAL MATTERS

Under oversight of the Site Remediation Section of the Railroad Commission of Texas, Energen Resources Corporation is currently in the process of cleanup and remediation of oil and gas wastes in nine reserve pits in Mitchell County, Texas. The Borrower estimates that the cleanup, remediation and related costs will approximate $3.4 million of which $1.9 million has been incurred and $0.5 million has been reserved. Also included is a preliminary estimate of $1 million of exposure for further remediation which may be required by the Railroad Commission and is pending further review by the Borrower.

During January 2014, Energen Resources Corporation responded to a General Notice and Information Request from the Environmental Protection Agency (EPA) regarding the Reef Environmental Site in Sylacauga, Talladega County, Alabama. The letter identifies Energen Resources Corporation as a potentially responsible party (PRP) under The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) for the cleanup of the Site. In 2008, Energen Resources Corporation hired a third party to transport approximately 3,000 gallons of non-hazardous wastewater to Reef Environmental for wastewater treatment. Reef Environmental ceased operating its wastewater treatment system in 2010. Due to its one time use of Reef Environmental for a small volume of non-hazardous wastewater, Energen Resources Corporation has not accrued a liability for cleanup of the Site.
