ARTICLE II

THE CREDITS

Section 2.01 Commitments . Subject to the terms and conditions set forth herein, each Lender agrees to make 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 such Lender’s Commitment or (b) the total Revolving Credit Exposures exceeding the total Commitments. 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 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 $100,000 and not less than $500,000. At the time that each ABR Borrowing is made, such Borrowing shall be in an aggregate amount that is an integral multiple of $100,000 and not less than $500,000; 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(e). Borrowings of more than one Type may be outstanding at the same time, provided that there shall not at any time be more than a total of eight (8) Eurodollar Borrowings outstanding. 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 . If requested by a Lender, the Loans made by such Lender shall be evidenced by a single promissory note of the Borrower in substantially the form of Exhibit A,

27

dated, in the case of (i) any Lender party hereto as of the date of this Agreement, as of the date of this Agreement, (ii) any Lender that becomes a party hereto pursuant to an Assignment and Assumption, as of the effective date of the Assignment and Assumption, or (iii) any Lender that becomes a party hereto in connection with an increase in the Aggregate Elected Commitment Amounts pursuant to Section 2.06(c), as of the effective date of such increase, payable to such Lender in a principal amount equal to its Maximum Credit Amount as in effect on such date, and otherwise duly completed. In the event that any Lender’s Maximum Credit Amount increases or decreases for any reason (whether pursuant to Section 2.06, Section 12.04(b) or otherwise), the Borrower shall deliver or cause to be delivered, to the extent such Lender is then holding a Note, on the effective date of such increase or decrease, a new Note payable to such Lender in a principal amount equal to its Maximum Credit Amount after giving effect to such increase or decrease, and otherwise duly completed, and each Lender shall return to the Borrower the Note so replaced. 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, the Borrower shall notify the Administrative Agent of such request by telephone (a) in the case of a Eurodollar Borrowing, not later than 12:00 noon, 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 noon, New York City time, on the date 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(e). Each such telephonic Borrowing Request shall be irrevocable and shall be confirmed promptly by hand delivery or facsimile or, subject to Section 12.01(b), e-mail 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:

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 total Commitments (i.e., the least of (x) the Aggregate Maximum Credit Amounts, (y) the then effective Borrowing Base, and (z) the Aggregate Elected Commitment Amounts).

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 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.

(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;

(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 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 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 . Each Lender shall make each Loan to be made by it hereunder on the proposed date thereof by wire transfer of immediately available funds by 1:00 p.m., New York City time, 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 ABR Loans made to finance the reimbursement of an LC Disbursement as provided in Section 2.08(e) shall be remitted by the Administrative Agent to the Issuing Bank. 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

30

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 to ABR Loans. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender’s Loan included in such Borrowing. Any payment by the Borrower shall be without prejudice to any claim the Borrower may have against a Lender that shall have failed to make such payment to the Administrative Agent.

Section 2.06 Termination and Reduction of Aggregate Maximum Credit Amounts; Increase and Reduction of Aggregate Elected Commitment Amounts .

(a) Scheduled Termination of Commitments . Unless previously terminated, the Commitments shall terminate on the Maturity Date.

(ii) The Borrower shall notify the Administrative Agent of any election to terminate or reduce the Aggregate Maximum Credit Amounts 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 Aggregate Maximum Credit Amounts 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

31

Administrative Agent on or prior to the specified effective date) if such condition is not satisfied. Any termination or reduction of the Aggregate Maximum Credit Amounts shall be permanent and may not be reinstated. Each reduction of the Aggregate Maximum Credit Amounts shall be made ratably among the Lenders in accordance with each Lender’s Applicable Percentage.

(c) Increase and Reduction of Aggregate Elected Commitment Amounts .

(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 8.12(a) and (c), and, in the case of an Interim Redetermination, pursuant to Section 8.12(b) and (c), and (B) such other reports, data and supplemental information, including the information provided pursuant to Section 8.12(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 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 other Debt, the Credit Parties’ other assets, liabilities, fixed charges, cash flow, business, properties, management, hedged and unhedged exposure to price, interest rate and operating cost changes, and price and production scenarios) as the Administrative Agent deems appropriate in its sole discretion and consistent with its normal oil and gas lending criteria as it exists at the particular time. In no event shall the Proposed Borrowing Base exceed the Aggregate Maximum Credit Amounts;

(ii) The Administrative Agent shall notify the Borrower and the Lenders of the Proposed Borrowing Base (the “ Proposed Borrowing Base Notice ”) 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 or deemed to have been approved by all of the Lenders 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

35

approved by the Required Lenders 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, 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, at the end of such 15-day period, all of the 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 been 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, all of the Lenders or the Required Lenders, as applicable, have not approved or been deemed to have approved, as aforesaid, then the Administrative Agent shall (A) notify the Borrower of the Proposed Borrowing Base and which Lenders have not approved or been deemed to have approved of the Proposed Borrowing Base, and (B) 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, all of the 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 all of the Lenders or the Required Lenders, as applicable, pursuant to Section 2.07(c)(iii) or adjusted pursuant to Section 2.07(e) or (f), the Administrative Agent shall 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 8.12(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 notice, or (B) if the Administrative Agent shall not have received the Engineering Reports required to be delivered by the Borrower pursuant to Section 8.12(a) and (c) in a timely and complete manner, then on the Business Day next succeeding delivery of such notice; and

(ii) in the case of an Interim Redetermination, on the Business Day next succeeding delivery of such 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) or Section 8.13(c), whichever occurs first. Notwithstanding the foregoing, no Scheduled Redetermination, Interim Redetermination, or adjusted Borrowing Base shall become effective until the New Borrowing Base Notice related thereto is received by the Borrower.

36

(e) Reduction of Borrowing Base Upon Issuance of Permitted Unsecured Notes . In addition to the other redeterminations of the Borrowing Base provided for herein, and notwithstanding anything to the contrary set forth herein, upon the issuance of any Permitted Unsecured Notes permitted by Section 9.02(h) after the Effective Date, the Borrowing Base then in effect shall be automatically reduced by an amount equal to the product of 0.25 multiplied by the stated principal amount of such Permitted Unsecured Notes (without regard to any initial issue discount), and, in each case, 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 Issuing Bank, and the Lenders on such date until the next redetermination or modification of the Borrowing Base pursuant to this Agreement; provided, that, notwithstanding the foregoing to the contrary, no such reduction of the Borrowing Base shall occur with respect to (i) the first $300,000,000 of Permitted Unsecured Notes issued by the Borrower or any Restricted Subsidiary following the Effective Date or (ii) the issuance of any Permitted Unsecured Notes to refinance or replace any then existing Permitted Unsecured Notes (up to the principal amount of such refinanced Permitted Unsecured Notes plus accrued interest, any applicable premium and transaction expenses).

(f) Reduction of Borrowing Base upon Sale of Properties or Termination of Swap Agreements . In addition to the other redeterminations of the Borrowing Base provided for herein, if at any time the aggregate Borrowing Base Value of Properties sold or disposed of and Swap Agreements in respect of commodities terminated or otherwise monetized, in each case pursuant to Section 9.11(d), in any period between Redetermination Dates exceeds ten percent (10%) of the Borrowing Base as of the last Redetermination Date, then the Borrowing Base shall be automatically reduced, effective immediately upon such sale or disposition (or, in the case of a Swap Agreement, termination or other monetization) by an amount equal to the Borrowing Base Value of such Properties sold or disposed of and Swap Agreements in respect of commodities terminated or otherwise monetized. Immediately upon such reduction, if applicable, the Borrowing Base shall be automatically redetermined to reflect such reduction and shall become the new Borrowing Base effective and applicable to the Borrower, the Administrative Agent, the Issuing Bank and the Lenders until the next redetermination or other adjustment of the Borrowing Base pursuant to this Agreement.

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. 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 . The Existing Letters of Credit shall be deemed to have been issued hereunder as of the Effective Date. To request the issuance of a Letter of Credit (or the amendment, renewal or extension of an outstanding Letter of Credit), the Borrower shall hand deliver or facsimile (or transmit by

37

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 five (5) 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 the Aggregate Elected Commitment Amounts 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 total Commitments (i.e., the least of (1) the Aggregate Maximum Credit Amounts, (2) the then effective Borrowing Base and (3) the Aggregate Elected Commitment Amounts). No letter of credit issued by the Issuing Bank (if the Issuing Bank is not the Administrative Agent) shall be deemed to be a “Letter of Credit” issued under this Agreement unless the Issuing Bank has requested and received written confirmation from the Administrative Agent that the representations by Borrower contained in the foregoing clauses (x) and (y) are true and correct.

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.

(c) Expiration Date . Each Letter of Credit shall expire at or prior to the close of business on the earlier of (i) the date that is one year after the date of the issuance of such Letter of Credit (or, in the case of any renewal or extension thereof, one year after such renewal or extension) and (ii) the date that is five Business Days prior to the Maturity Date. Each Letter of Credit with a one (1) year term may provide for the renewal thereof for additional one (1) year periods; provided that no such period shall extend beyond the date described in clause (ii) of the preceding sentence.

38

(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 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 by paying to the Administrative Agent an amount equal to such LC Disbursement not later than 12:00 noon, New York City time, 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 12:00 noon, 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, unless the Borrower has notified the Administrative Agent that it intends to reimburse all or part of such LC Disbursement without using Loan proceeds or has submitted a Borrowing Request with respect thereto, 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. If the Borrower fails to make such payment when due, the Administrative Agent shall notify each Lender of the applicable LC Disbursement, the payment then due from the Borrower in respect thereof and such Lender’s Applicable Percentage thereof. Promptly following receipt of such notice, each Lender shall pay to the Administrative Agent its Applicable Percentage of the payment then due from the Borrower, in the same manner as provided in Section 2.05 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)

39

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 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, nor shall the provisions of Section 12.03 be construed to provide indemnity to the Issuing Bank with respect to any such failure or the consequences thereof. The parties hereto expressly agree that, in the absence of gross negligence or willful misconduct on the part of the Issuing Bank (as finally determined by a court of competent jurisdiction), the Issuing Bank shall be deemed to have exercised 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 facsimile) of such demand for payment and whether the

40

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 (acting at the direction of the Required Lenders) demanding the deposit of cash collateral pursuant to this Section 2.08(j), (ii) the LC Exposure exceeds the LC Commitment at any time as a result of a reduction in the Borrowing Base or (iii) 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 Event of Default, the LC Exposure (or such lesser amount as may be agreed to by the Required Lenders), in the case of the LC Exposure exceeding the LC Commitment, the amount of such excess, 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 plus any accrued and unpaid interest thereon; provided that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become immediately due and payable, without demand or other notice of any kind, upon the occurrence of any Event of Default with respect to the Borrower 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

41

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 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 three Business Days after all Events of Default have been cured or waived.

(k) Defaulting Lenders . Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a Defaulting Lender, and any LC Exposure exists at the time a Lender becomes a Defaulting Lender, then:

(i) all or any part of such LC Exposure shall be reallocated among the non-Defaulting Lenders in accordance with their respective Applicable Percentages but only to the extent (x) the sum of all non-Defaulting Lenders’ Revolving Credit Exposures does not exceed the total of all non-Defaulting Lenders’ Commitments and (y) the conditions set forth in Section 6.02 are satisfied at such time;

(ii) if the reallocation described in clause (i) above cannot, or can only partially, be effected, the Borrower shall within one (1) Business Day following notice by the Administrative Agent cash collateralize such Defaulting Lender’s LC Exposure (after giving effect to any partial reallocation pursuant to clause (i) above) in accordance with the procedures set forth in Section 2.08(j) for so long as such LC Exposure is outstanding;

42

(iii) if the Borrower cash collateralizes any portion of such Defaulting Lender’s LC Exposure pursuant to this Section 2.08(k), the Borrower shall not be required to pay any fees to such Defaulting Lender pursuant to Section 3.05(b) with respect to such Defaulting Lender’s LC Exposure during the period such Defaulting Lender’s LC Exposure is cash collateralized;

(iv) if the LC Exposure of the non-Defaulting Lenders is reallocated pursuant to this Section 2.08(k), then the fees payable to the Lenders pursuant to Section 3.05(a) and Section 3.05(b) shall be adjusted in accordance with such non-Defaulting Lenders’ Applicable Percentages; or

(v) if any Defaulting Lender’s LC Exposure is neither cash collateralized nor reallocated pursuant to this Section 2.08(k), then, without prejudice to any rights or remedies of the Issuing Bank or any Lender hereunder, all commitment fees that otherwise would have been payable to such Defaulting Lender (solely with respect to the portion of such Defaulting Lender’s Commitment that was utilized by such LC Exposure) under Section 3.05(a) and letter of credit fees payable under Section 3.05(b) with respect to such Defaulting Lender’s LC Exposure shall be payable to the Issuing Bank until such LC Exposure is cash collateralized and/or reallocated.

Notwithstanding any provision of this Agreement to the contrary, so long as any Lender is a Defaulting Lender, the Issuing Bank shall not be required to issue, amend or increase any Letter of Credit, unless it is satisfied that the related exposure will be 100% covered by the Commitments of the non-Defaulting Lenders and/or cash collateral will be provided by the Borrower in accordance with Section 2.08(j), and participating interests in any such newly issued or increased Letter of Credit shall be allocated among non-Defaulting Lenders in a manner consistent with Section 2.08(k)(i) (and any Defaulting Lender shall not participate therein).

(l) 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.

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 Loan on 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 for ABR Loans, but in no event to exceed the Highest Lawful Rate.

43

(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 for Eurodollar Loans, but in no event to exceed the Highest Lawful Rate.

(c) 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) has occurred and is continuing, or (ii) the Required Lenders so elect (or direct the Administrative Agent to so elect) in connection with the occurrence and continuance of any other Event of Default, then in each case all Loans outstanding shall bear interest, after as well as before judgment, at a rate per annum equal to two percent (2%) plus the rate otherwise applicable to such Loans (including the Applicable Margin applicable with respect to such Loans), but in no event to exceed the Highest Lawful Rate. In the case of the foregoing clause (i), such increase in the interest rate shall become effective automatically upon the occurrence of any such Event of Default. In the case of the foregoing clause (ii), such increase in the interest rate shall become effective upon the election of the Required Lenders (or the election of the Administrative Agent at the direction of the Required Lenders).

(d) 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 interest accrued pursuant to Section 3.02(c) shall be payable on demand. 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 in the event of any conversion of any Eurodollar Loan prior to the end of the current Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion.

(e) 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, 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 determines (which determination shall be conclusive absent manifest error) that adequate and reasonable means do not exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate 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;

44

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

Section 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 .

Promptly following receipt of any such notice relating to a Borrowing, the Administrative Agent shall advise the Lenders of the contents thereof. Each partial prepayment of any Borrowing shall be in an amount that would be permitted in the case of an advance of a Borrowing of the same Type as provided in Section 2.02.

(ii) Upon any redetermination of or adjustment to the amount of the Borrowing Base in accordance with Section 2.07 (other than Section 2.07(e) and Section 2.07(f))

45

or Section 8.13(c), if there exists a Borrowing Base Deficiency, then the Borrower shall, within five (5) Business Days following receipt of the New Borrowing Base Notice or the date the adjustment occurs, as applicable, deliver written notice to the Administrative Agent stating the action which the Borrower proposes to take to eliminate such Borrowing Base Deficiency, and the Borrower shall thereafter, at its option, either:

(A) within thirty (30) days following its delivery of the Election Notice, by instruments reasonably satisfactory in form and substance to the Administrative Agent, provide the Administrative Agent with additional security consisting of Oil and Gas Properties owned by the Borrower or its Restricted Subsidiaries with value and quality satisfactory to the Administrative Agent and the Required Lenders in their sole discretion to eliminate such Borrowing Base Deficiency,

(B) within thirty (30) days following its delivery of the Election Notice, prepay without premium or penalty, the Borrowings in an amount sufficient to eliminate such Borrowing Base Deficiency and, 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 remaining Borrowing Base Deficiency to be held as cash collateral as provided in Section 2.08(j),

(C) prepay (and thereafter pay), without premium or penalty, the principal amount necessary to eliminate such Borrowing Base Deficiency in not more than six (6) equal monthly installments plus accrued interest thereon with the first such monthly payment being due within thirty (30) days following the effectiveness of such redetermination or other adjustment of the Borrowing Base (and, 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 remaining Borrowing Base Deficiency to be held as cash collateral as provided in Section 2.08(j)), or

(D) by any combination of prepayment and additional security as provided in the preceding clauses (A), (B) or (C), 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.

(iii) Upon any adjustment to the Borrowing Base pursuant Section 2.07(e) or Section 2.07(f), if there exists a Borrowing Base Deficiency, the Borrower shall (A) prepay Borrowings in an aggregate principal amount, if any, necessary to fully eliminate such Borrowing Base Deficiency, and (B) if any Borrowing Base Deficiency remains after prepaying all Borrowings as a result of an LC Exposure, pay to the Administrative Agent on behalf of the Lenders an amount equal to such remaining Borrowing Base Deficiency to be held as cash collateral as provided in Section 2.08(j). The Borrower shall make such prepayment and/or deposit of cash collateral on the date it receives notice from the Administrative Agent of such adjustment of the Borrowing Base.

(iv) Promptly following the incurrence of any Debt by any Credit Party (other than Debt permitted under Section 9.02), the Borrower shall prepay the Loans in an aggregate amount equal to one hundred percent (100%) of the Net Proceeds received in respect

46

of such Debt. Nothing in this paragraph is intended to permit any Credit Party to incur Debt other than as permitted under Section 9.02, and any such incurrence of Debt shall be a violation of Section 9.02 and a breach of this Agreement.

(v) Promptly following the receipt of Net Proceeds by any Credit Party in respect of any Casualty Event, the Borrower shall prepay the Loans in an aggregate amount equal to one hundred percent (100%) of such Net Proceeds (to the extent that such Net Proceeds exceed the aggregate amount of $1,000,000 in any fiscal year); provided , that if the Borrower delivers to the Administrative Agent a certificate of a Responsible Officer to the effect that the Credit Parties intend to apply the Net Proceeds from such Casualty Event (or a portion thereof as specified in such certificate), within 180 days after receipt of such Net Proceeds, to purchase assets useful in the business of the Credit Parties, then, so long as no Default or Borrowing Base Deficiency then exists, no prepayment shall be required pursuant to this paragraph in respect of the Net Proceeds specified in such certificate; provided further, that to the extent any such Net Proceeds have not been so applied by the end of such 180 day period, a prepayment shall be required in an amount equal to such Net Proceeds that have not been so applied.

(vi) Each prepayment of Borrowings pursuant to this Section 3.04(c) shall be applied, first, ratably to any ABR Borrowings then outstanding, and, second, 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.

The Borrower agrees to pay to the Administrative Agent for the account of each Lender 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. 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 interest 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).

47

(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, which shall accrue at the rate of 0.25% per annum on the average daily amount of the LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the 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, provided that in no event shall such fee be less than $500 during any quarter, 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. Participation fees and fronting fees accrued through and including the last day of March, June, September and December of each year shall be payable on the third Business Day following such last day, commencing on the first such date to occur after the 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 fees 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 interest 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 in the Fee Letter.

(e) Commitment Increase Fees . On the effective date of any increase to the total Commitments, the Borrower agrees to pay to the Administrative Agent, for the account of each Lender (including any Additional Lender) whose Commitment is increasing on such date, a Commitment increase fee in an amount to be set forth in a separate written agreement.

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 12:00 noon, 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, absent manifest error. 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 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 resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and participations in LC Disbursements and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Loans and participations in LC Disbursements of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and participations in LC Disbursements; provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this 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

49

Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or participations in LC Disbursements to any assignee or participant, other than to the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this 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) 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. If at any time prior to the acceleration or maturity of the Loans, the Administrative Agent shall receive any payment in respect of principal of a Loan or a reimbursement of an LC Disbursement while one or more Defaulting Lenders shall be party to this Agreement, the Administrative Agent shall apply such payment first to the Borrowing(s) for which such Defaulting Lender(s) shall have failed to fund its pro rata share until such time as such Borrowing(s) are paid in full or each Lender (including each Defaulting Lender) is owed its Applicable Percentage of all Loans then outstanding. 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 has occurred and is continuing, (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

50

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);

(ii) subject any Lender to any Taxes (other than (A) Indemnified Taxes, or (B) Excluded 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 London interbank market any other condition affecting this Agreement or Eurodollar Loans made by such Lender;

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

(b) Capital Requirements . If any Lender or the Issuing Bank determines that any Change in Law 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, upon receipt of a certificate described in the following subsection (c), 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) and reasonably detailed calculations therefor 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.

51

(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 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 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 compensate each Lender for the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest which would have accrued on the principal amount of such Loan had such event not occurred, at the Adjusted LIBO Rate that would have been applicable to such Loan, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest which would accrue on such principal amount for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the eurodollar market.

A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section 5.02 and reasonably detailed calculations therefor shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 30 days after receipt thereof.

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 Withholding Agent shall be required by applicable law to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions

52

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 applicable Withholding Agent shall make such deductions and (iii) the applicable Withholding Agent 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 or Other 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 or Other Taxes imposed or asserted on or attributable to amounts payable under this Section 5.03) and any penalties, interest and reasonable out-of-pocket expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate 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. Notwithstanding the foregoing, Borrower shall not be required to compensate any Administrative Agent, Lender or Issuing Bank pursuant to this Section 5.03(c) for any Indemnified Taxes to the extent that such Indemnified Taxes (i) are attributable to the period beginning 180 days after such Administrative Agent, Lender or Issuing Bank received written notice of the imposition of the Indemnified Taxes if such Administrative Agent, Lender or Issuing Bank has not made a written demand for compensation pursuant to this Section 5.03(c) within 180 days after the receipt of such written notice, and (ii) would not have been imposed if such Lender had designated a different lending office pursuant to Section 5.04(a) or such Lender had been replaced pursuant to Section 5.04(b).

(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).

53

(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, 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 prescribed by law or reasonably requested by the Withholding Agent, such properly completed and executed documentation prescribed by law or 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 (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) any Lender that is a “United States person” as defined in Section 7701(a)(3) of the Code 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;

54

(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 H-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 H-2 or Exhibit H-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 H-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 this Agreement would be subject to United States federal withholding tax imposed by FATCA if such Lender fails 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

55

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) Tax Refunds . If an Administrative Agent or a Lender determines, in its reasonable discretion, that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified by the Borrower or with respect to which the Borrower has paid additional amounts pursuant to this Section 5.03, it shall pay over such refund to the Borrower (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section 5.03 with respect to the Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of such Administrative Agent or such Lender and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund); provided , that the Borrower, upon the request of such Administrative Agent or such Lender, agrees to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to such Administrative Agent or such Lender in the event such Administrative Agent or such Lender is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this Section 5.03(h), in no event will the applicable Administrative Agent or Lender be required to pay any amount to the Borrower pursuant to this Section 5.03(h) the payment of which would place the applicable Administrative Agent or Lender in a less favorable net-after Tax position than such Administrative Agent or Lender 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 Section 5.03 shall not be construed to require any Administrative Agent or any Lender to make available its Tax returns (or any other information relating to its Taxes which it deems confidential) to the Borrower or any other Person.

Section 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 additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 5.03, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 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 of Lenders . If (i) any Lender requests compensation under Section 5.01, (ii) the Borrower is required to pay any additional amount to any Lender or any

56

Governmental Authority for the account of any Lender pursuant to Section 5.03, (iii) any Lender is a Defaulting Lender, (iv) any Lender is a Non-Consenting Lender, or (v) any Lender has Affected Loans under Section 5.05, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent (and in the case of clause (iv) above, within thirty (30) days after the date such Lender becomes a Non-Consenting Lender), (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 its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment) or (B) require such Lender to be removed as a Lender under this Agreement and the other Loan Documents with a corresponding reduction in the Aggregate Elected Commitment Amounts and Aggregate Maximum Credit Amount equal to the Elected Commitment and Maximum Credit Amount, respectively, of such Lender; provided that (1) if a Lender is removed as a Lender hereunder, the Borrower has paid such Lender all amounts due and owing under this Agreement and the other Loan Documents, including all principal, accrued interest, fees and breakage costs, (2) in the case of a required assignment of interest, the Borrower shall have received the prior written consent of the Administrative Agent and the Issuing Bank, which consent shall not unreasonably be withheld, (3) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and participations in LC Disbursements, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts) and (4) 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. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

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.

Section 7.14 Subsidiaries .

Each Restricted Subsidiary’s jurisdiction of organization, name as listed in the public

66

records of its jurisdiction of organization and organizational identification number in its jurisdiction of organization is stated on Schedule 7.14 (or as set forth in a notice delivered pursuant to Section 8.01(k)).

After giving full effect to the Excepted Liens, and with the exception of Immaterial Title Deficiencies, the Borrower or the Restricted Subsidiary specified as the owner owns the net interests in production attributable to the Hydrocarbon Interests as reflected in the most recently delivered Reserve Report, and the ownership of such Properties shall not in any material respect obligate the Borrower or such Restricted Subsidiary to bear the costs and expenses relating to the maintenance, development and operations of each such Property in an amount in excess of the working interest of each Property set forth in the most recently delivered Reserve Report that is not offset by a corresponding proportionate increase in the Borrower’s or such Restricted Subsidiary’s net revenue interest in such Property.

(b) Except as would not reasonably be expected to have a Material Adverse Effect, all oil and gas leases and agreements necessary for the conduct of the business of the Borrower and its Restricted Subsidiaries are valid and subsisting, in full force and effect, and there exists no default or event or circumstance which with the giving of notice or the passage of time or both would give rise to a default under any such lease or leases.

Section 7.18 Swap Agreements and Qualified ECP Guarantor . Schedule 7.18, as of the date hereof, and after the date hereof, each report required to be delivered by the Borrower pursuant to Section 8.01(e), sets forth, a true and complete list of all Swap Agreements of the Borrower and each Restricted Subsidiary, the material terms thereof (including the type, term, effective date, termination date and notional amounts or volumes), the estimated net mark to market value thereof, all credit support agreements relating thereto not listed on Schedule 7.18 (including any margin required or supplied) and the counterparty to each such agreement.

Section 7.21 Foreign Corrupt Practices . Neither the Borrower nor any of its Subsidiaries, nor any director, officer, agent, employee or Affiliate of the Borrower or any of its Subsidiaries is aware of or has taken any action, directly or indirectly, that would result in a material violation by such Persons of the FCPA, including making use of the mails or any means or instrumentality of interstate commerce corruptly in furtherance of an offer, payment, promise to pay or authorization of the payment of any money, or other property, gift, promise to give, or authorization of the giving of anything of value to any “foreign official” (as such term is defined in the FCPA) or any foreign political party or official thereof or any candidate for foreign political office, in contravention of the FCPA; and, the Borrower, its Subsidiaries and its and their Affiliates have conducted their business in material compliance with the FCPA and have instituted and maintain policies and procedures designed to ensure, and which are reasonably expected to continue to ensure, continued compliance therewith.

76

of the chief engineer of the Borrower who shall certify such Reserve Report to be based on information that was prepared in good faith based upon assumptions believed to be reasonable at the time and to have been prepared in accordance with the procedures used in the immediately preceding January 1 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 forty-five (45) days following the receipt of such request.

(b) If the Borrower has provided title information for additional Properties under Section 8.13(a), the Borrower shall, within 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 except for Excepted Liens (other than Excepted Liens described in clauses (e), (g) and (h) of such definition) having an equivalent value or (iii) deliver title information in form and substance acceptable to the Administrative

77

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 75% of the total value of the proved Oil and Gas Properties evaluated by such Reserve Report.

(c) If the Borrower is unable to cure (or elects not to cure) any title defect requested by the Administrative Agent or the Lenders to be cured within the 60-day period or the Borrower does not comply with the requirements to provide acceptable title information covering 75% of the value of the proved 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 60-day period has elapsed, such unacceptable Mortgaged Property shall not count towards the 75% 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 75% of the value of the proved Oil and Gas Properties. This new Borrowing Base shall become effective immediately after receipt of such notice.

Section 8.14 Collateral and Guarantors .

(a) In connection with each redetermination of the Borrowing Base, the Borrower shall review the Reserve Report and the list of current Mortgaged Properties (as described in Section 8.12(c)(vi)) to ascertain whether the Mortgaged Properties represent at least 80% of the total value of the proved Oil and Gas Properties evaluated in the most recently completed Reserve Report after giving effect to exploration and production activities, acquisitions, dispositions and production.

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 50% of the then 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 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 75% of the then 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 maturity date of such Debt.

(b) If, after the end of any calendar quarter, commencing with calendar quarter ending June 30, 2014, the Borrower determines that the aggregate notional volumes of all Swap Agreements in respect of commodities for such calendar quarter (other than basis differential swaps on volumes already hedged pursuant to other Swap Agreements) exceeded 100% of actual production of Hydrocarbons in such calendar quarter, then the Borrower (i) shall promptly notify the Administrative Agent of such determination and (ii) if requested by the Required Lenders, shall within 30 days of such determination, terminate (only to the extent such terminations are permitted pursuant to Section 9.11), create off-setting positions, or otherwise unwind or monetize (only to the extent such unwinds or monetizations are permitted pursuant to Section 9.11) existing Swap Agreements such that, at such time, future hedging volumes will not exceed 100% of reasonably anticipated projected production for the then-current and any succeeding calendar quarters.

(c) In no event shall any Swap Agreement contain any requirement, agreement or covenant for the Borrower or any Restricted Subsidiary to post collateral or margin to secure their obligations under such Swap Agreement or to cover market exposures other than

90

any requirement, agreement or covenant to enter into or maintain the Security Instruments; provided , that, notwithstanding the foregoing, the Borrower and its Restricted Subsidiaries may request that Letters of Credit be issued hereunder for the benefit of, and to secure the obligations owing to, its counterparties in respect of commodity Swap Agreements so long as the aggregate amount of such Letters of Credit outstanding at any one time shall not exceed $10,000,000.

(d) The Borrower will not, and will not permit any Restricted Subsidiary to, terminate or monetize 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 9.11.

(e) For purposes of entering into or maintaining Swap Agreement trades or transactions under Section 9.16(a)(i) and Section 9.16(b), respectively, forecasts of reasonably anticipated production from the Borrower’s and its Restricted Subsidiaries’ Proved Reserves or Proved Developed Producing Reserves, as applicable, 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 9.17 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 or any Equity Interests in any Subsidiaries.

Section 9.18 Amendments to Permitted Unsecured Notes Documents . The Borrower will not, and will not permit any Restricted Subsidiary to, amend, modify, waive or otherwise change, consent or agree to any amendment, modification, waiver or other change to, any of the terms of the Permitted Unsecured Notes if (a) the effect thereof would be to shorten the maturity of the Permitted Unsecured Notes or shorten the average life or increase the amount of any payment of principal thereof or increase the rate or scheduled recurring fee or add call or pre-payment premiums or shorten any period for payment of interest thereon, (b) such action requires the payment of a consent fee (howsoever described), (c) such action increases the interest rate margins applicable to the Permitted Unsecured Notes or alters the calculation of interest thereunder, (d) such action adds or amends any representations and warranties, covenants or events of default to be more restrictive or burdensome than this Agreement without this Agreement being contemporaneously amended to add similar provisions or (e) such action adds or changes any redemption, put or prepayment provisions; provided that the foregoing shall not prohibit the execution of supplemental agreements to add guarantors if required by the terms thereof ( provided that any such guarantor also guarantees the Indebtedness pursuant to the Guaranty and Pledge Agreement and each of Borrower and such guarantor otherwise complies with Section 8.14); and provided further that nothing in this Section 9.18 shall prohibit the Borrower from (i) extending, refinancing, or renewing of the Permitted Unsecured Notes pursuant to Section 9.02(h) or (ii) permitting any Restricted Subsidiary to extend, refinance or renew the Permitted Unsecured Notes pursuant to Section 9.02(h).

ARTICLE XI

THE AGENTS

Section 11.01 Appointment; Powers . Each of the Lenders and the Issuing Bank hereby irrevocably (subject to Section 11.06) 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

95

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 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 proposed closing date 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, 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, no Agent (other than the Administrative Agent) 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, Required Lenders or each Lender, as applicable, (or such

96

other number or percentage of the 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 the Required 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 that is a Lender. 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 removal of the retiring Administrative Agent, then the retiring Administrative Agent may, on behalf of the Lenders and the Issuing Bank, appoint a successor Administrative Agent which shall be a bank with an office in New York, New York, or an Affiliate of any such bank. Upon the acceptance of its appointment as Administrative Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its

97

duties and obligations hereunder. The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the Administrative Agent’s resignation hereunder, the provisions of this Article XI and Section 12.03 shall continue in effect for the benefit of such retiring Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as Administrative Agent.

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 Arranger 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.

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 Restricted 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

98

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 .

(a) Each Lender and the Issuing Bank hereby authorizes the Administrative Agent to take the following actions and the Administrative Agent hereby agrees to take such actions at the request of the Borrower:

(c) 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.

Section 12.02 Waivers; Amendments .

(a) No failure on the part of the Administrative Agent, any other Agent, the Issuing Bank or any Lender to exercise and no delay in exercising, and no course of dealing with respect to, any right, power or privilege, or any abandonment or discontinuance of steps to enforce such right, power or privilege, under any of the Loan Documents shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege under any of the Loan Documents preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies of the Administrative Agent, any other Agent, the Issuing Bank and the Lenders hereunder and under the other Loan Documents are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or any other Loan Document or consent to any departure by the Borrower therefrom shall in any event be effective unless the same shall be permitted by Section 12.02(b), and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan or issuance of a Letter of Credit shall not be construed as a waiver of any Default, regardless of whether the Administrative Agent, any other Agent, any Lender or the Issuing Bank may have had notice or knowledge of such Default at the time.

(b) Neither this Agreement nor any provision hereof nor any Security Instrument nor any provision thereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Borrower and the Majority Lenders or by the Borrower and the Administrative Agent with the consent of the Majority Lenders; provided that no such agreement shall (i) increase the Commitment, Elected Commitment or the Maximum Credit Amount of any Lender without the written consent of such Lender, (ii) increase the Borrowing Base without the written consent (or deemed approval, as set forth herein) of each Lender (other than any Defaulting Lender), decrease or maintain the Borrowing Base without the consent (or deemed consent, as set forth herein) of the Required Lenders, or modify Section 2.07 in any manner that results in an increase in the Borrowing Base without the consent of each Lender (other than any Defaulting Lender), (iii) reduce the principal amount of any Loan or LC Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, or reduce any other Indebtedness hereunder or under any other Loan Document, without the written consent of each Lender affected thereby, (iv) postpone the scheduled date of payment or

101

prepayment of the principal amount of any Loan or LC Disbursement, or any interest thereon, or any fees payable hereunder, or any other Indebtedness hereunder or under any other Loan Document, or reduce the amount of, waive or excuse any such payment, or postpone or extend the Termination Date without the written consent of each Lender affected thereby, (v) change Section 4.01(b) or Section 4.01(c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, (vi) waive or amend Section 3.04(c), Section 6.01, Section 10.02(c) or Section 12.14 or change the definition of the terms “Domestic Subsidiary”, “Foreign Subsidiary” or “Subsidiary”, without the written consent of each Lender (other than any Defaulting Lender), (vii) release any Guarantor (except as set forth in Section 11.10 or in the Guaranty and Pledge Agreement), release all or substantially all of the collateral (other than as provided in Section 11.10), or reduce the percentage set forth in Section 8.14(a) to less than 80%, without the written consent of each Lender (other than any Defaulting Lender), or (viii) change any of the provisions of this Section 12.02(b) or the definitions of “Majority Lenders”, “Required Lenders”, “Supermajority Lenders” or any other provision hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or under any other Loan Documents or make any determination or grant any consent hereunder or any other Loan Documents, without the written consent of each Lender (other than any Defaulting Lender); provided further that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent, any other Agent, or the Issuing Bank hereunder or under any other Loan Document without the prior written consent of the Administrative Agent, such other Agent or the Issuing Bank, as the case may be. Notwithstanding the foregoing, (x) any supplement to Schedule 7.14 (Subsidiaries) shall be effective simply by delivering to the Administrative Agent a supplemental schedule clearly marked as such and, upon receipt, the Administrative Agent will promptly deliver a copy thereof to the Lenders, (y) the Borrower and the Administrative Agent may amend this 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.

THE BORROWER AND ITS SUBSIDIARIES BY THE BORROWER AND ITS SUBSIDIARIES, (vii) ANY ASSERTION THAT THE LENDERS WERE NOT ENTITLED TO RECEIVE THE PROCEEDS RECEIVED PURSUANT TO THE SECURITY INSTRUMENTS, (viii) ANY ENVIRONMENTAL LAW APPLICABLE TO THE BORROWER OR ANY SUBSIDIARY OR ANY OF THEIR PROPERTIES OR OPERATIONS, INCLUDING, THE PRESENCE, GENERATION, STORAGE, RELEASE, THREATENED RELEASE, USE, TRANSPORT, DISPOSAL, ARRANGEMENT OF DISPOSAL OR TREATMENT OF HAZARDOUS MATERIALS ON OR AT ANY OF THEIR PROPERTIES, (ix) THE BREACH OR NON-COMPLIANCE BY THE BORROWER OR ANY SUBSIDIARY WITH ANY ENVIRONMENTAL LAW APPLICABLE TO THE BORROWER OR ANY SUBSIDIARY, (x) THE PAST OWNERSHIP BY THE BORROWER OR ANY SUBSIDIARY OF ANY OF THEIR PROPERTIES OR PAST ACTIVITY ON ANY OF THEIR PROPERTIES WHICH, THOUGH LAWFUL AND FULLY PERMISSIBLE AT THE TIME, COULD RESULT IN PRESENT LIABILITY, (xi) THE PRESENCE, USE, RELEASE, STORAGE, TREATMENT, DISPOSAL, GENERATION, THREATENED RELEASE, TRANSPORT, ARRANGEMENT FOR TRANSPORT OR ARRANGEMENT FOR DISPOSAL OF HAZARDOUS MATERIALS ON OR AT ANY OF THE PROPERTIES OWNED OR OPERATED BY THE BORROWER OR ANY SUBSIDIARY OR ANY ACTUAL OR ALLEGED PRESENCE OR RELEASE OF HAZARDOUS MATERIALS ON OR FROM ANY PROPERTY OWNED OR OPERATED BY THE BORROWER OR ANY OF ITS SUBSIDIARIES, (xii) ANY ENVIRONMENTAL LIABILITY RELATED IN ANY WAY TO THE BORROWER OR ANY OF ITS SUBSIDIARIES, OR (xiii) ANY OTHER ENVIRONMENTAL, HEALTH OR SAFETY CONDITION IN CONNECTION WITH THE LOAN DOCUMENTS, OR (xiv) ANY ACTUAL OR PROSPECTIVE CLAIM, LITIGATION, INVESTIGATION OR PROCEEDING RELATING TO ANY OF THE FOREGOING, WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY AND REGARDLESS OF WHETHER ANY INDEMNITEE IS A PARTY THERETO, AND SUCH INDEMNITY SHALL EXTEND TO EACH INDEMNITEE NOTWITHSTANDING THE SOLE OR CONCURRENT NEGLIGENCE OF EVERY KIND OR CHARACTER WHATSOEVER, WHETHER ACTIVE OR PASSIVE, WHETHER AN AFFIRMATIVE ACT OR AN OMISSION, INCLUDING WITHOUT LIMITATION, ALL TYPES OF NEGLIGENT CONDUCT IDENTIFIED IN THE RESTATEMENT (SECOND) OF TORTS OF ONE OR MORE OF THE INDEMNITEES OR BY REASON OF STRICT LIABILITY IMPOSED WITHOUT FAULT ON ANY ONE OR MORE OF THE INDEMNITEES; provided THAT SUCH INDEMNITY SHALL NOT, AS TO ANY INDEMNITEE, BE AVAILABLE TO THE EXTENT THAT SUCH LOSSES, CLAIMS, DAMAGES, LIABILITIES OR RELATED EXPENSES (A) ARE DETERMINED BY A COURT OF COMPETENT JURISDICTION BY FINAL AND NONAPPEALABLE JUDGMENT TO HAVE RESULTED FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF SUCH INDEMNITEE, (B) RELATE TO CLAIMS BETWEEN OR AMONG ANY OF THE LENDERS, THE AGENTS, ARRANGER OR ANY OF THEIR SHAREHOLDERS, PARTNERS OR MEMBERS OR (C) IN RESPECT OF ANY PROPERTY FOR ANY OCCURRENCE ARISING FROM THE ACTS OR OMISSIONS OF ANY AGENT OR ANY LENDER DURING THE PERIOD AFTER WHICH SUCH PERSON, ITS SUCCESSORS OR ASSIGNS SHALL HAVE OBTAINED POSSESSION OF SUCH PROPERTY (WHETHER BY FORECLOSURE OR DEED IN LIEU OF FORECLOSURE, AS MORTGAGEE-IN-POSSESSION OR OTHERWISE).

(a) To the extent permitted by applicable law, no party hereto shall assert, and each party hereto hereby waives, any claim against any other party hereto, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any other Loan Document or any agreement or instrument contemplated hereby or thereby, the Transactions, any Loan or Letter of Credit or the use of the proceeds thereof.

(d) All amounts due under this Section 12.03 shall be payable promptly after written demand therefor.

Section 12.04 Successors and Assigns .

(a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby (including any Affiliate of the Issuing Bank that issues any Letter of Credit), except that (i) the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by the Borrower without such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section 12.04. Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby (including any Affiliate of the Issuing Bank that issues any Letter of Credit), Participants (to the extent provided in Section 12.04(c)) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent, the Issuing Bank and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement, and except for the foregoing Persons there are no third party beneficiaries to this Agreement.

(b) (i) Subject to the conditions set forth in Section 12.04(b)(ii), any Lender may assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it) with the prior written consent (such consent not to be unreasonably withheld) of:

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

105

(B) the Administrative Agent, provided that no consent of the Administrative Agent shall be required for an assignment to an assignee that is a Lender immediately prior to giving effect to such assignment.

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

(A) except in the case of an assignment to a Lender or an Affiliate of a Lender or an assignment of the entire remaining amount of the assigning Lender’s Commitment or Loans, the amount of the Commitment or Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent) shall not be less than $10,000,000 unless each of the Borrower and the Administrative Agent otherwise consent, provided that no such consent of the Borrower shall be required if an Event of Default has occurred and is continuing;

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

(C) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee payable by the assigning Lender of $3,500; provided that the Administrative Agent may, in its sole discretion, elect to waive such processing and recordation fee in the case of any assignment;

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

(E) in no event may any Lender assign all or a portion of its rights and obligations under this Agreement to the Borrower, any Affiliate of the Borrower, any natural person, or an Industry Competitor; and

(F) no such assignment shall be made to a Defaulting Lender or any of its subsidiaries, or any Person who, upon becoming a Lender hereunder, would constitute a Defaulting Lender or a Subsidiary of a Defaulting Lender.

(iii) Subject to Section 12.04(b)(iv) and the acceptance and recording thereof by the Administrative Agent, 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 assignment by a Defaulting Lender will constitute a waiver or release of any claim of

106

any party hereunder arising from that Lender’s 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 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 Maximum Credit Amount and Elected Commitment 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, and the Borrower, the Administrative Agent, the Issuing Bank and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower, 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 Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in Section 12.04(b) 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).

(c) (i) Any Lender may, without the consent of the Borrower, the Administrative Agent or the Issuing Bank, sell participations to one or more banks or other Persons (other than the Borrower, any Affiliate of the Borrower 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) such Participant must first agree to comply with Section 12.11, (D) no such participation may be sold to a natural Person or an Industry Competitor, (E) the Borrower, the Administrative Agent, the Issuing Bank and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the proviso to Section 12.02(b) that 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

107

Participant shall be entitled to the benefits of Section 5.01, Section 5.02 and Section 5.03 and shall be subject to the requirements of and limitations in Section 5.01, 5.02, 5.03 and 5.05 (it being understood that the documentation required under Section 5.03(g) shall be delivered to the participating Lender, i.e., the Lender selling such participation) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to Section 12.04(b); provided that such Participant shall not be entitled at any time 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 at such time. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 5.03 unless the Borrower is notified of the participation sold to such Participant and such Participant complies with Section 5.03(d) as though it were a Lender. Each Lender that sells participation agrees, at the Borrower’s request and expense, to use reasonable efforts to cooperate with the Borrower to effectuate the provisions of Section 5.05 with respect to any Participant. 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.

(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.

108

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.

Delivery of an executed counterpart of a signature page of this Agreement by facsimile or other electronic transmission (e.g. .pdf) 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 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; provided that the failure to give such notice shall not affect the validity of such setoff and application.

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 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.

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 Swap Agreement including any 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 another Secured Swap Provider that is not a Lender or an Affiliate of a Lender.

(d) In the event of default by the Borrower or any other Credit Party in payment of the Indebtedness, or any part thereof, when such Indebtedness becomes due, either by its terms or as the result of the exercise of any power to accelerate, each Grantor shall, on demand, and without further notice of dishonor and without any notice having been given to such Grantor previous to such demand of the acceptance by Secured Parties of this Agreement, and without any notice having been given to such Grantor previous to such demand of the creating or incurring of such Indebtedness, pay the amount due thereon to Secured Parties at Administrative Agent’s office as set forth in the Credit Agreement, and it shall not be necessary for any Secured Party, in order to enforce such payment by any Grantor, first, to institute suit or exhaust its remedies against Borrower, any other Grantor or others liable on such Indebtedness, to have the Borrower joined with any Grantor in any suit brought under this Agreement or to enforce its rights against any security which shall ever have been given to secure such indebtedness; provided, however, that in the event any Secured Party elects to enforce and/or exercise any remedies it may possess with respect to any security for the Indebtedness prior to demanding payment from any Grantor, such Grantor shall nevertheless be obligated hereunder for any and all sums still owing to Secured Parties on the Indebtedness and not repaid or recovered incident to the exercise of such remedies.

(e) Each Grantor hereby subordinates and makes inferior any and all indebtedness now or at any time hereafter owed by any Credit Party to any Grantor to the

Indebtedness evidenced by the Credit Agreement and agrees if an Event of Default shall have occurred and be continuing, not to permit any Credit Party to repay, or to accept payment from any Credit Party of, such indebtedness or any part thereof without the prior written consent of Majority Lenders. Each Grantor further agrees that if Administrative Agent so requests, such indebtedness of Borrower to such Grantor shall be collected, enforced and received by such Grantor as trustee for Administrative Agent (for the benefit of the Secured Parties) and shall be paid over to Administrative Agent (for the benefit of the Secured Parties) on account of the Indebtedness but without reducing or affecting in any manner the liability of such Grantor under the other provisions of this Agreement.

(f) Each Grantor hereby agrees that to the extent that any Grantor shall have paid more than its proportionate share of any payment made hereunder, such Grantor shall be entitled to seek and receive contribution from and against any other Grantor hereunder which has not paid its proportionate share of such payment. Each Grantor’s right of contribution shall be subject to the terms and conditions of Section 2.1(g) . The provisions of this Section 2.1(f) shall in no respect limit the obligations and liabilities of any Grantor to the Secured Parties, and each Grantor shall remain liable to the Secured Parties for the full amount guaranteed by such Grantor hereunder.

(g) Notwithstanding any payment made by any Grantor hereunder or any set off or application of funds of any Grantor by any Secured Party, no Grantor shall be entitled to be subrogated to any of the rights of any Secured Party against the Borrower or any Grantor or any Collateral security or guaranty or right of offset held by any Secured Party for the payment of the Indebtedness, nor shall any Grantor seek or be entitled to seek any indemnity, exoneration, participation, contribution or reimbursement from the Borrower or any Grantor in respect of payments made by such Grantor hereunder, until all amounts owing to the Secured Parties by the Credit Parties on account of the Indebtedness are Paid In Full. If any amount shall be paid to any Grantor on account of such subrogation rights at any time when all of the Indebtedness shall not have been Paid In Full, such amount shall be held by such Grantor in trust for Administrative Agent (for the benefit of the Secured Parties), segregated from other funds of such Grantor, and shall, forthwith upon receipt by such Grantor, be turned over to Administrative Agent (for the benefit of the Secured Parties) in the exact form received by such Grantor (duly endorsed by such Grantor to Administrative Agent, if required), to be applied against the Indebtedness whether matured or unmatured.

(h) If all or any part of the Indebtedness at any time is secured, each Grantor agrees that Administrative Agent and/or Lenders may at any time and from time to time, at their discretion and with or without valuable consideration, allow substitution or withdrawal of Collateral or other security and release Collateral or other security or compromise or settle any amount due or owing under the Credit Agreement or amend or modify in whole or in part the Credit Agreement or any Loan Document executed in connection with same without impairing or diminishing the Indebtedness of each Grantor hereunder. Each Grantor further agrees that if any Credit Party executes in favor of any Secured Party any collateral agreement, mortgage or other security instrument, the exercise by any Secured Party of any right or remedy thereby conferred on such Secured Party shall be wholly discretionary with such Secured Party, and that the exercise or failure to exercise any such right or remedy shall in no way impair or diminish the obligation of each Grantor hereunder. Each Grantor further agrees that Secured Parties and the

5

Administrative Agent shall not be liable for their failure to use diligence in the collection of the Indebtedness or in preserving the liability of any person liable for the Indebtedness, and each Grantor hereby waives presentment for payment, notice of nonpayment, protest and notice thereof (including, notice of acceleration), and diligence in bringing suits against any Person liable on the Indebtedness, or any part thereof.

(i) Each Grantor agrees that Secured Parties, in their discretion, may (but subject to any applicable provisions of the Loan Documents) (i) bring suit against all Grantors (including, without limitation, each Grantor hereunder) of the Indebtedness jointly and severally or against any one or more of them, (ii) compound or settle with any one or more of such Grantors for such consideration as Secured Parties may deem proper, and (iii) release one or more of such Grantors from liability hereunder, and that no such action shall impair the rights of Secured Parties to collect the Indebtedness (or the unpaid balance thereof) from other such Grantors of the Indebtedness, or any of them, not so sued, settled with or released. Each Grantor agrees, however, that nothing contained in this paragraph, and no action by Secured Parties permitted under this paragraph, shall in any way affect or impair the rights or Indebtedness of such Grantors among themselves.

(j) Each Grantor acknowledges and agrees that any interest on any portion of the Indebtedness which accrues after the commencement of any insolvency or bankruptcy proceeding (or, if interest on any portion of the Indebtedness ceases to accrue by operation of law by reason of the commencement of said proceeding, such interest as would have accrued on such portion of the Indebtedness if said proceedings had not been commenced) shall be included in the Indebtedness because it is the intention of each Grantor and the Secured Parties that the Indebtedness which is guaranteed by each Grantor pursuant to this Guaranty should be determined without regard to any rule of law or order which may relieve any Credit Party of any portion of such Indebtedness. Each Grantor will permit any trustee in bankruptcy, receiver, debtor in possession, assignee for the benefit of creditors or similar person to pay the Secured Parties or Administrative Agent, or allow the claim of the Secured Parties or Administrative Agent in respect of, any such interest accruing after the date on which such proceeding is commenced.

(k) Notice to any Grantor of the acceptance of this Agreement and of the making, renewing or assignment of the Indebtedness and each item thereof, are hereby expressly waived by each Grantor.

ARTICLE VI

EVENTS OF DEFAULT AND REMEDIES

6.1 Events of Default . The occurrence of any “Event of Default” under, and as defined in, the Credit Agreement shall constitute an Event of Default hereunder.

6.2 Remedies .

(a) Upon the occurrence and during the continuance of an Event of Default, the Administrative Agent may, or at the direction of the Required Lenders, shall, exercise any or all of the following rights and remedies:

13

(b) The Administrative Agent, on behalf of the Secured Parties, may comply with any applicable state or federal law requirements in connection with a disposition of the Collateral and compliance will not be considered to adversely affect the commercial reasonableness of any sale of the Collateral.

(c) The Administrative Agent shall have the right upon any such public sale or sales and, to the extent permitted by law, upon any such private sale or sales, to purchase for the benefit of the Administrative Agent and the Secured Parties, the whole or any part of the Collateral so sold, free of any right of equity redemption, which equity redemption the Grantor hereby expressly releases.

(d) Until the Administrative Agent is able to affect a sale, lease, or other disposition of Collateral, the Administrative Agent shall have the right to hold or use Collateral, or any part thereof, to the extent that it deems appropriate for the purpose of preserving Collateral or its value or for any other purpose deemed appropriate by the Administrative Agent. The Administrative Agent may, if it so elects, seek the appointment of a receiver or keeper to take possession of Collateral and to enforce any of the Administrative Agent’s remedies (for the benefit of the Administrative Agent and Secured Parties), with respect to such appointment without prior notice or hearing as to such appointment.

(e) Notwithstanding the foregoing, neither the Administrative Agent nor any Secured Party shall be required to 1. make any demand upon, or pursue or exhaust any of their rights or remedies against, any Grantor, any other obligor, guarantor, pledgor or any other Person with respect to the payment of the Indebtedness or to pursue or exhaust any of their rights or remedies with respect to any Collateral therefor or any direct or indirect guarantee thereof, 2. marshal the Collateral or any guarantee of the Indebtedness or to resort to the Collateral or any such guarantee in any particular order, or 3. effect a public sale of any Collateral.

(f) Each Grantor recognizes that the Administrative Agent may be unable to effect a public sale of any or all the Pledged Collateral and may be compelled to resort to one or more private sales thereof in accordance with clause (a) above. Each Grantor also acknowledges that any private sale may result in prices and other terms less favorable to the seller than if such sale were a public sale and, notwithstanding such circumstances, agrees that any such private sale shall not be deemed to have been made in a commercially unreasonable manner solely by virtue of such sale being private. The Administrative Agent shall be under no obligation to delay a sale of any of the Pledged Collateral for the period of time necessary to permit any Grantor or

14

the issuer of the Pledged Collateral to register such securities for public sale under the Securities Act of 1933, as amended, or under applicable state securities laws, even if the applicable Grantor and the issuer would agree to do so.

(g) Each Grantor understands and agrees that any amounts of any Grantor on account with any Lender may, if an Event of Default shall have occurred and be continuing, be offset to satisfy the obligations of such Grantor hereunder.

(a) assemble and make available to the Administrative Agent the Collateral and all books and records relating thereto at any place or places specified by the Administrative Agent, whether at a Grantor’s premises or elsewhere; and

(b) permit the Administrative Agent, by the Administrative Agent’s representatives and agents, to enter, occupy and use any premises where all or any part of the Collateral, or the books and records relating thereto, or both, are located, to take possession of all or any part of the Collateral or the books and records relating thereto, or both, to remove all or any part of the Collateral or the books and records relating thereto, or both, and to conduct sales of the Collateral, without any obligation to pay the Grantor for such use and occupancy.

15

(b) All acts of said attorney or designee are hereby ratified and approved. The powers conferred on the Administrative Agent, for the benefit of the Administrative Agent and Secured Parties, under this Section 7.1 are solely to protect the Administrative Agent’s interests in the Collateral and shall not impose any duty upon the Administrative Agent or any Secured Party to exercise any such powers.

7.2 Proxy . EACH GRANTOR HEREBY IRREVOCABLY CONSTITUTES AND APPOINTS THE ADMINISTRATIVE AGENT AS ITS PROXY AND ATTORNEY-IN-FACT (TO THE EXTENT SET FORTH IN SECTION 7.1 ABOVE) WITH RESPECT TO ITS PLEDGED COLLATERAL, INCLUDING THE RIGHT TO VOTE SUCH PLEDGED COLLATERAL, WITH FULL POWER OF SUBSTITUTION TO DO SO DURING THE CONTINUANCE OF AN EVENT OF DEFAULT. IN ADDITION TO THE RIGHT TO VOTE ANY SUCH PLEDGED COLLATERAL, THE APPOINTMENT OF THE ADMINISTRATIVE AGENT AS PROXY AND ATTORNEY-IN-FACT SHALL INCLUDE THE RIGHT TO EXERCISE DURING THE CONTINUANCE OF AN EVENT OF DEFAULT ALL OTHER RIGHTS, POWERS, PRIVILEGES AND REMEDIES TO WHICH A HOLDER OF SUCH PLEDGED COLLATERAL WOULD BE ENTITLED (INCLUDING GIVING OR WITHHOLDING WRITTEN CONSENTS OF SHAREHOLDERS, CALLING SPECIAL MEETINGS OF SHAREHOLDERS AND VOTING AT SUCH MEETINGS). SUCH PROXY SHALL BE EFFECTIVE, AUTOMATICALLY AND WITHOUT THE NECESSITY OF ANY ACTION (INCLUDING ANY TRANSFER OF ANY SUCH PLEDGED COLLATERAL ON THE RECORD BOOKS OF THE ISSUER THEREOF) BY ANY PERSON (INCLUDING THE ISSUER OF SUCH PLEDGED COLLATERAL OR ANY OFFICER OR AGENT THEREOF), UPON THE OCCURRENCE OF A DEFAULT.

7.3 Nature of Appointment; Limitation of Duty . THE APPOINTMENT OF THE ADMINISTRATIVE AGENT AS PROXY AND ATTORNEY-IN-FACT IN THIS ARTICLE VII IS COUPLED WITH AN INTEREST AND SHALL BE IRREVOCABLE UNTIL THE DATE ON WHICH THIS AGREEMENT IS TERMINATED IN ACCORDANCE WITH SECTION 8.13 .

ARTICLE VIII

GENERAL PROVISIONS

8.1 Waivers . Each Grantor hereby waives notice of the time and place of any public sale or the time after which any private sale or other disposition of all or any part of the Collateral may be made. To the extent such notice may not be waived under applicable law, any notice made shall be deemed reasonable if sent to the Grantors, addressed as set forth in Article IX , at least ten days prior to 8.1.1 the date of any such public sale or 8.1.2 the time after which any such private sale or other disposition may be made. To the maximum extent permitted by applicable law, each Grantor waives all claims, damages, and demands against the Administrative Agent or any Secured Party arising out of the repossession, retention or sale of the Collateral, except such as arise solely out of the gross negligence or willful misconduct of the Administrative Agent or such Secured Party as finally determined by a court of competent jurisdiction. To the extent it may lawfully do so, each Grantor absolutely and irrevocably waives and relinquishes the benefit and advantage of, and covenants not to assert against the Administrative Agent or any Secured Party, any valuation, stay, appraisal, extension, moratorium, redemption or similar laws and any and all rights or defenses it may have as a surety now or hereafter existing which, but for this provision, might be applicable to the sale of any Collateral made under the judgment, order or decree of any court, or privately under the power of sale conferred by this Agreement, or otherwise. Except as otherwise specifically provided herein, each Grantor hereby waives presentment, demand, protest or any notice (to the maximum extent permitted by applicable law) of any kind in connection with this Agreement or any Collateral.

8.2 Limitation on Administrative Agent’s and any Secured Party’s Duty with Respect to the Collateral . The Administrative Agent and each Secured Party shall use reasonable care with respect to the Collateral in its possession or under its control. Neither the Administrative Agent nor any Secured Party shall have any other duty as to any Collateral in its possession or control or in the possession or control of any agent or nominee of the Administrative Agent or such Secured Party, or any income thereon or as to the preservation of rights against prior parties or any other rights pertaining thereto. To the extent that applicable law imposes duties on the Administrative Agent to exercise remedies in a commercially reasonable manner, each Grantor acknowledges and agrees that it is commercially reasonable for the Administrative Agent 8.2.1 to fail to incur expenses deemed significant by the Administrative Agent to prepare Collateral for disposition, 8.2.2 to advertise dispositions of Collateral through publications or media of general circulation, whether or not the Collateral is of a specialized nature, 8.2.3 to contact other Persons, whether or not in the same business as such Grantor, for expressions of interest in acquiring all or any portion of such Collateral, 8.2.4 to hire one or more professional auctioneers to assist in the disposition of Collateral, whether or not the Collateral is of a specialized nature, 8.2.5 to dispose of Collateral by utilizing internet sites that provide for the auction of assets of the types included in the Collateral or that have the reasonable capacity of doing so, or that match buyers and sellers of assets, or 8.2.6 to the extent deemed appropriate by the Administrative Agent, to obtain the services of other brokers, investment bankers, consultants and other professionals to assist the Administrative Agent in the collection or disposition of any of the Collateral. Each Grantor acknowledges that the purpose of this Section 8.2 is to provide non-exhaustive indications of what actions or omissions by the Administrative Agent would be commercially reasonable in the Administrative Agent’s exercise of remedies against the Collateral and that

17

other actions or omissions by the Administrative Agent shall not be deemed commercially unreasonable solely on account of not being indicated in this Section 8.2 . Without limitation upon the foregoing, nothing contained in this Section 8.2 shall be construed to grant any rights to any Grantor or to impose any duties on the Administrative Agent that would not have been granted or imposed by this Agreement or by applicable law in the absence of this Section 8.2 .

8.3 Specific Performance of Certain Covenants . Each Grantor acknowledges and agrees that a breach of any of the covenants contained herein will cause irreparable injury to the Administrative Agent and the Secured Parties, that the Administrative Agent and Secured Parties have no adequate remedy at law in respect of such breaches and therefore agrees that the covenants of the Grantors contained herein shall be specifically enforceable against the Grantors.

8.4 Administrative Agent Performance of Grantor Obligations . Without having any obligation to do so, the Administrative Agent may during the continuance of an Event of Default perform or pay any obligation which any Grantor has agreed to perform or pay in this Agreement and the Grantors shall reimburse the Administrative Agent for any amounts paid by the Administrative Agent pursuant to this Section 8.4 . The Grantors’ obligation to reimburse the Administrative Agent pursuant to the preceding sentence shall be Indebtedness payable on demand.

8.5 Dispositions Not Authorized .
