SECTION 2

AMOUNT AND TERMS OF COMMITMENTS

2.1 Commitments. (a) Subject to the terms and conditions hereof, including, without limitation, the satisfaction of the conditions precedent set forth in Section 6 hereof, each Lender severally agrees to make Loans (“Loans”) to the Borrowers from time to time during the Commitment Period in an aggregate principal amount at any one time outstanding not to exceed the amount of such Lender’s Commitment, provided that no Lender shall make any Loans if, after giving effect thereto, the sum of such Lender’s Loans and Commitment Percentage of Letter of Credit Outstandings (in each case, after giving effect to the Loans requested to be made and the Letters of Credit requested to be issued on such date) exceeds the lesser of (i) such Lender’s Commitment and (ii) such Lender’s Commitment Percentage of the Borrowing Base then in effect. During the Commitment Period, the Borrowers may use the Commitments by borrowing, prepaying the Loans in whole or in part, and reborrowing, all in accordance with the terms and conditions hereof.

-21-

(b) The Loans may from time to time be (i) Eurodollar Loans, (ii) ABR Loans or (iii) a combination thereof, as determined by the Borrowers’ Representative and notified to the Administrative Agent in accordance with Sections 2.2 and 4.3, provided that no Loan shall be made as a Eurodollar Loan after the day that is one month prior to the Termination Date.

2.2 Procedure for Borrowing. The Borrowers may borrow under the Commitments during the Commitment Period on any Business Day, provided that the Borrowers’ Representative shall give the Administrative Agent irrevocable notice (which notice must be received by the Administrative Agent prior to (a) 12:00 Noon, New York City time, three Business Days prior to the requested Borrowing Date, if all or any part of the requested Loans initially are to be Eurodollar Loans or (b) 10:00 a.m. on the requested Borrowing Date if the requested Loans are ABR Loans), specifying (i) the amount to be borrowed, (ii) the requested Borrowing Date, (iii) whether the borrowing is to be of Eurodollar Loans, ABR Loans or a combination thereof and (iv) if the borrowing is to be entirely or partly of Eurodollar Loans, the respective amounts of each such Type of Loan and the respective lengths of the initial Interest Periods therefor. Each borrowing under the Commitments shall be in an amount equal to (x) in the case of ABR Loans, $5,000,000 or a whole multiple of $1,000,000 in excess thereof (or, if the then Available Commitments, or the amount of outstanding Eurodollar Loans after any repayment of any Eurodollar Loans, are less than $5,000,000, such lesser amount) and (y) in the case of Eurodollar Loans, $5,000,000 or a whole multiple of $1,000,000 in excess thereof. Upon receipt of any such notice from the Borrowers’ Representative, the Administrative Agent shall promptly notify each Lender thereof. Each Lender will make the amount of its pro rata share of each borrowing available to the Administrative Agent for the account of the Borrowers at the office of the Administrative Agent specified in Section 11.2 prior to 12:00 Noon, New York City time, on the Borrowing Date requested by the Borrowers’ Representative in funds immediately available to the Administrative Agent. Such borrowing will then be made available to the Borrowers by the Administrative Agent crediting the account of the Borrowers specified in the borrowing notice with the aggregate of the amounts made available to the Administrative Agent by the Lenders and in like funds as received by the Administrative Agent.

2.3 Repayment of Loans. (a) The Borrowers hereby unconditionally promise to pay to the Administrative Agent for the account of each Lender the then unpaid principal amount of each Loan of such Lender on the Termination Date (or such earlier date on which the Loans become due and payable pursuant to Section 9.1). The Borrowers hereby further agree to pay interest on the unpaid principal amount of the Loans from time to time outstanding from the date hereof to but not including the date the Loans are paid in full at the rates per annum, and on the dates, set forth in Section 4.1.

-22-

(b) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing indebtedness of the Borrowers to such Lender resulting from each Loan of such Lender from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time under this Agreement.

(c) The Administrative Agent shall maintain the Register pursuant to Section 11.6(d), and a subaccount therein for each Lender, in which shall be recorded (i) the amount of each Loan made hereunder, the Type thereof and each Interest Period applicable thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrowers to each Lender hereunder and (iii) both the amount of any sum received by the Administrative Agent hereunder from the Borrowers and each Lender’s share thereof.

(d) The entries made in the Register and the accounts of each Lender maintained pursuant to Section 11.6(d) shall, to the extent permitted by applicable law, be prima facie evidence of the existence and amounts of the obligations of the Borrowers therein recorded; provided, however, that the failure of the Administrative Agent or any Lender to maintain the Register or any such account, or any error therein, shall not in any manner affect the obligation of the Borrowers to repay (with applicable interest) the Loans made to the Borrowers by such Lender in accordance with the terms of this Agreement.

2.4 Evidence of Debt. Upon the request of any Lender, the Borrowers will execute and deliver to such Lender a promissory note of the Borrowers evidencing the Loans of such Lender, substantially in the form of Exhibit A with appropriate insertions as to date and principal amount (a “Note”).

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

(i) Such Defaulting Lender’s right to approve or disapprove any amendment, waiver or consent with respect to this Agreement or any other Loan Document shall be restricted as set forth in Section 11.1.

(ii) Any payment of principal, interest, fees or other amounts received by the Administrative Agent for the account of that Defaulting Lender (whether voluntary or mandatory, at maturity, or otherwise or received by the Administrative Agent from such Defaulting Lender pursuant to Section 11.8) shall be applied at such time or times as may be determined by the Administrative Agent as follows:

first, to the payment of any amounts owing by that Defaulting Lender to the Administrative Agent hereunder;

second, to the payment on a pro rata basis of any amounts owing by such Defaulting Lender to the Issuing Lenders hereunder;

third, to Cash Collateralize the Issuing Lenders’ Fronting Exposure with respect to such Defaulting Lender in accordance with Section 3.8;

-23-

fourth, as the Borrowers may request (so long as no Default or Event of Default exists), to the funding of any Loan in respect of which that Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Administrative Agent;

fifth, if so determined by the Administrative Agent and the Borrowers, to be held in a deposit account and released pro rata in order to (x) satisfy such Defaulting Lender’s potential future funding obligations with respect to Loans under this Agreement and (y) Cash Collateralize the Issuing Lenders’ future Fronting Exposure with respect to such Defaulting Lender with respect to future Letters of Credit issued under this Agreement, in accordance with Section 3.8;

sixth, to the payment of any amounts owing to the Lenders and the Issuing Lenders as a result of any judgment of a court of competent jurisdiction obtained by any Lender or any Issuing Lender against that Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement;

seventh, so long as no Default or Event of Default exists, to the payment of any amounts owing to the Borrowers as a result of any judgment of a court of competent jurisdiction obtained by a Borrower against such Defaulting Lender as a result of that Defaulting Lender’s breach of its obligations under this Agreement; and

eighth, to such Defaulting Lender or as otherwise directed by a court of competent jurisdiction; provided that if (x) such payment is a payment of the principal amount of any Loans or L/C Disbursements in respect of which that Defaulting Lender has not fully funded its appropriate share, and (y) such Loans were made or the related Letters of Credit were issued at a time when the conditions set forth in Section 6.2 were satisfied or waived, such payment shall be applied solely to pay the Loans of, and L/C Disbursements owed to, all Non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Loans of, or L/C Disbursements owed to, such Defaulting Lender until such time as all Loans and funded and unfunded participations in L/C Disbursements are held by the Lenders pro rata in accordance with the Commitments without giving effect to Section 2.5(a)(iv).

Any payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender or to post Cash Collateral pursuant to this Section 2.5(a)(ii) shall be deemed paid to and redirected by such Defaulting Lender, and each Lender irrevocably consents hereto.

(iii) Certain Fees.

(A) No Defaulting Lender shall be entitled to receive any fee described in Section 4.6(a) for any period during which that Lender is a Defaulting Lender (and the Borrowers shall not be required to pay any such fee that otherwise would have been required to have been paid to that Defaulting Lender).

(B) Each Defaulting Lender shall be entitled to receive fees described in 3.3 for any period during which it is a Defaulting Lender only to the extent allocable to the percentage of the stated amount of Letters of Credit for which it has provided Cash Collateral pursuant to Section 3.8.

-24-

(C) With respect to any fee described in Section 4.6(a) or Section 3.3 not required to be paid to any Defaulting Lender pursuant to clause (A) or (B) above, the Borrowers shall (x) pay to each Non-Defaulting Lender that portion of any such fee otherwise payable to such Defaulting Lender with respect to such Defaulting Lender’s participation in Letter of Credit Outstandings that has been reallocated to such Non-Defaulting Lender pursuant to clause (iv) below, (y) pay to the Issuing Lender the amount of any such fee otherwise payable to such Defaulting Lender to the extent allocable to the Issuing Lender’s Fronting Exposure to such Defaulting Lender, and (z) not be required to pay the remaining amount of any such fee.

(iv) All or any part of such Defaulting Lender’s participation in Letter of Credit Outstandings shall be reallocated among the Non-Defaulting Lenders in accordance with their respective Commitment Percentages (calculated without regard to such Defaulting Lender’s Commitment) but only to the extent that such reallocation does not cause any Non-Defaulting Lender’s Aggregate Credit Exposure to exceed such Non-Defaulting Lender’s Commitment. No reallocation hereunder shall constitute a waiver or release of any claim of any party hereunder against a Defaulting Lender arising from that Lender having become a Defaulting Lender, including any claim of a Non-Defaulting Lender as a result of such Non-Defaulting Lender’s increased exposure following such reallocation.

(v) If the reallocation described in clause (iv) above cannot, or can only partially, be effected, the Borrowers shall, without prejudice to any right or remedy available to it hereunder or under law, Cash Collateralize the Issuing Lenders’ Fronting Exposure in accordance with the procedures set forth in Section 3.8.

(b) If the Borrowers, the Administrative Agent, and each Issuing Lender agree in writing that a Lender is no longer a Defaulting Lender, the Administrative Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include arrangements with respect to any Cash Collateral), that Lender will, to the extent applicable, purchase at par that portion of outstanding Loans of the other Lenders or take such other actions as the Administrative Agent may determine to be necessary to cause the Loans and funded and unfunded participations in Letters of Credit to be held pro rata by the Lenders in accordance with the Commitments (without giving effect to Section 2.5(a)(iv)), whereupon such Lender will cease to be a Defaulting Lender; provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrowers while that Lender was a Defaulting Lender; and provided, further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender.

(c) So long as any Lender is a Defaulting Lender, no Issuing Lender shall be required to issue, extend, renew or increase any Letter of Credit unless it is satisfied that it will have no Fronting Exposure after giving effect thereto.

3.1 The L/C Commitment. (a) Subject to the terms and conditions hereof, including, without limitation, the satisfaction of the conditions precedent set forth in Section 6 hereof, the Issuing Lender, in reliance on the agreements of the other Lenders set forth in Section 3.4(a), agrees to issue letters of credit (the “Letters of Credit”) for the account of any Borrower or any Subsidiary or Affiliate of a Borrower in which EPEP has a direct or indirect investment, on any Business Day during the Commitment Period in such form as may be approved from time to time by the Issuing Lender; provided that the Issuing Lender shall not issue any Letter of Credit if, after giving effect to such issuance and after giving effect to any Loans requested to be made or Letters of Credit requested to be issued on such date (i) the sum of the Loans and Letter of Credit Outstandings would exceed the lesser of (A) the Commitments and (B) the Borrowing Base then in effect or (ii) the Letter of Credit Outstandings would exceed the L/C Sublimit. Each Letter of Credit shall (x) be issued to support obligations of any Borrower or any Subsidiary or Affiliate of a Borrower in which EPEP has a direct or indirect investment, contingent or otherwise, and (y) shall expire no later than the earlier of (I) three years (or such later date agreed to by the Issuing Lender) after the date of issuance and (II) five Business Days prior to the Termination Date, provided that any Letter of Credit may provide for the extension thereof for additional one-year periods (which shall in no event extend beyond the date referred to in clause (II) above). Each Letter of Credit shall be denominated in Dollars.

(b) Each Letter of Credit shall be subject to the Uniform Customs or, at the option of the Issuing Lender if acceptable to the beneficiary, the ISP, and, to the extent not inconsistent therewith, the laws of the State of New York.

(d) No Issuing Lender shall be under any obligation to issue any Letter of Credit if any Lender is at that time a Defaulting Lender, unless the applicable Borrower or such Defaulting Lender has Cash Collateralized such Issuing Lender’s actual or potential Fronting Exposure (after giving effect to Section 2.5(a)(iv)) with respect to the Defaulting Lender arising from the Letter of Credit then proposed to be issued.

3.2 Procedure for Issuance of Letters of Credit. The Borrowers’ Representative may from time to time request that the Issuing Lender issue a Letter of Credit by delivering to the Issuing Lender and the Administrative Agent at their respective addresses for notices specified herein a letter of credit application. Upon receipt of any letter of credit application, the Issuing Lender will process such letter of credit application on (i) the Business Day on which such letter of credit application is received, provided that such letter of credit application is received no later than 11:00 a.m. (New York time) on such Business Day, or (ii) the first Business Day next succeeding receipt of such letter of credit application if received after such time. Upon receipt by the Issuing Lender of confirmation from the Administrative Agent that issuance of such Letter of Credit will not contravene Section 3.1, the Issuing Lender shall promptly issue the Letter of Credit requested thereby (but in no event shall the Issuing Lender be required to issue any Letter of Credit earlier than noon New York time on the Business Day of its receipt of the letter of credit application) by issuing the original of such Letter of Credit to the beneficiary thereof or as otherwise may be agreed by the Issuing Lender and the Borrowers’ Representative. The Issuing Lender shall furnish a copy of such Letter of Credit to the Borrowers’ Representative and the Administrative Agent promptly following the issuance thereof, and, thereafter, the Administrative Agent shall promptly furnish a copy thereof to the Lenders.

-26-

3.3 Fees, Commissions and Other Charges. (a) The Borrowers shall pay to the Administrative Agent, for the account of (i) the Issuing Lender and the Participating Lenders, a letter of credit commission with respect to each Letter of Credit, computed for the period from the date such Letter of Credit is issued to the date upon which the next payment is due under this Section 3.3(a) (and, thereafter, from the date of payment under this Section 3.3(a) to the date upon which the next payment is due under this Section 3.3(a)) at the rate per annum equal to the Applicable Margin in effect from time to time for Eurodollar Loans of the daily aggregate amount available to be drawn under such Letter of Credit during such period, and (ii) the Issuing Lender, a letter of credit commission with respect to each Letter of Credit in an amount equal to .20% per annum of the daily aggregate amount available to be drawn under such Letter of Credit. The letter of credit commissions payable pursuant to clause (i) and (ii) above shall be payable quarterly in arrears on the last day of each March, June, September and December, commencing June 30, 2011, and on the Termination Date.

(b) In addition to the foregoing fees and commissions, the Borrowers shall pay to the Issuing Lender (i) a fee of $750 for issuing each Letter of Credit, and (ii) a fee of $250 for amending any Letter of Credit.

(c) The Administrative Agent shall, promptly following its receipt thereof, distribute to the Issuing Lender and the Participating Lenders all fees and commissions received by the Administrative Agent for their respective accounts pursuant to this Section 3.3.

3.4 L/C Participations. (a) Effective on the date of issuance of each Letter of Credit issued after the Effective Date, the Issuing Lender irrevocably agrees to grant and hereby grants to each Participating Lender, and each Participating Lender irrevocably agrees to accept and purchase and hereby accepts and purchases from the Issuing Lender, on the terms and conditions hereinafter stated, for such Participating Lender’s own account and risk an undivided interest equal to such Participating Lender’s Commitment Percentage in the Issuing Lender’s obligations and rights under each Letter of Credit issued by the Issuing Lender and the amount of each draft paid by the Issuing Lender thereunder. Each Participating Lender unconditionally and irrevocably agrees with the Issuing Lender that, if a draft is paid under any Letter of Credit for which such Issuing Lender is not reimbursed in full by the Borrowers in accordance with the terms of this Agreement, such Participating Lender shall pay to the Administrative Agent, for the account of the Issuing Lender, upon demand at the Administrative Agent’s address specified in Section 11.2, an amount equal to such Participating Lender’s Commitment Percentage of the amount of such draft, or any part thereof, which is not so reimbursed. On the date that any Assignee becomes a Lender party to this Agreement in accordance with Section 11.6, participating interests in any outstanding Letters of Credit held by the transferor Lender from which such Assignee acquired its interest hereunder shall be proportionately reallotted between such Assignee and such transferor Lender. Each Participating Lender hereby agrees that its obligation to participate in each Letter of Credit, and to pay or to reimburse the Issuing Lender for its participating share of the drafts drawn or amounts otherwise paid thereunder, is absolute, irrevocable and unconditional and shall not be affected by any circumstances whatsoever (including, without limitation, the occurrence or continuance of any Default or Event of Default), and that each such payment shall be made without offset, abatement, withholding or other reduction whatsoever.

-27-

(b) If any amount required to be paid by any Participating Lender to the Issuing Lender pursuant to Section 3.4(a) in respect of any unreimbursed portion of any draft paid by the Issuing Lender under any Letter of Credit is paid to the Issuing Lender within three Business Days after the date such payment is due, such Participating Lender shall pay to the Administrative Agent, for the account of the Issuing Lender, on demand, an amount equal to the product of (i) such amount, times (ii) the daily average Federal Funds Effective Rate during the period from and including the date such draft is paid to the date on which such payment is immediately available to the Issuing Lender, times (iii) a fraction the numerator of which is the number of days that elapse during such period and the denominator of which is 360. If any such amount required to be paid by any Participating Lender pursuant to Section 3.4(a) is not in fact made available to the Administrative Agent, for the account of the Issuing Lender, by such Participating Lender within three Business Days after the date such payment is due, the Issuing Lender shall be entitled to recover from such Participating Lender, on demand, such amount with interest thereon calculated from such due date at the rate per annum applicable to ABR Loans hereunder. A certificate of the Issuing Lender submitted to any Participating Lender with respect to any amounts owing under this subsection shall be conclusive in the absence of manifest error.

(c) Whenever, at any time after the Issuing Lender has paid a draft under any Letter of Credit and has received from any Participating Lender its pro rata share of such payment in accordance with Section 3.4(a), the Issuing Lender receives any reimbursement on account of such unreimbursed portion, or any payment of interest on account thereof, the Issuing Lender will pay to the Administrative Agent, for the account of such Participating Lender, its pro rata share thereof; provided, however, that in the event that any such payment received by the Issuing Lender shall be required to be returned by the Issuing Lender, such Participating Lender shall return to the Administrative Agent for the account of the Issuing Lender, the portion thereof previously distributed to it.

3.5 Reimbursement Obligation of the Borrowers. If any draft shall be presented for payment under any Letter of Credit, the Issuing Lender shall notify the Borrowers and the Administrative Agent of the date and the amount thereof. The Borrowers agree to reimburse the Issuing Lender (whether with their own funds or with proceeds of the Loans) on each date on which the Issuing Lender pays a draft so presented under any Letter of Credit for the amount of (i) such draft so paid and (ii) any taxes, fees, charges or other costs or expenses incurred by the Issuing Lender in connection with such payment; provided that unless the Borrowers’ Representative shall have notified the Administrative Agent otherwise, the Borrowers’ obligations shall be financed with an ABR Loan made under this Section 3.5 in an equivalent amount and, to the extent so financed, the Borrowers’ obligation to reimburse such Letter of Credit disbursement shall be discharged and replaced by the resulting ABR Loan, which ABR Loans shall not be subject to the conditions precedent in Section 6.2. The borrowing date with respect to any such ABR Loans shall be the date of the remittance by the Issuing Lender of the proceeds of such drawing. Each such payment shall be made to the Issuing Lender at its address for notices specified herein in lawful money of the United States of America and in immediately available funds.

-28-

3.6 Obligations Absolute. The Borrowers’ obligations under this Section 3 shall be absolute and unconditional under any and all circumstances and irrespective of any set-off, counterclaim or defense to payment which the Borrowers or any other Person may have or have had against any Issuing Lender or any other Lender or any beneficiary of a Letter of Credit. The Borrowers also agree with the Issuing Lenders that the Issuing Lenders shall not be responsible for, and the Borrowers’ obligations under Section 3.5 shall not be affected by, among other things, the validity or genuineness of documents or of any endorsements thereon, even though such documents shall in fact prove to be invalid, fraudulent or forged, or any dispute between or among the Borrowers and any beneficiary of any Letter of Credit or any other party to which such Letter of Credit may be transferred or any claims whatsoever of the Borrowers against any beneficiary of such Letter of Credit or any such transferee. The Issuing Lenders shall not be liable for any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with any Letter of Credit, IN ALL CASES, WHETHER OR NOT CAUSED BY OR ARISING, IN WHOLE OR IN PART, OUT OF THE COMPARATIVE, CONTRIBUTORY OR SOLE NEGLIGENCE OF THE ISSUING LENDER, except for errors or omissions caused by such Issuing Lender’s gross negligence or willful misconduct. The Borrowers agree that any action taken or omitted by an Issuing Lender under or in connection with any Letter of Credit or the related drafts or documents, if done in the absence of gross negligence or willful misconduct and in accordance with the standards of care specified in the Uniform Commercial Code of the State of New York, including, without limitation, Article 5 thereof, shall be binding on the Borrowers and shall not result in any liability of such Issuing Lender to the Borrowers; provided that the foregoing shall not be construed to excuse such Issuing Lender from liability to a Borrower to the extent of any direct damages suffered by a Borrower that are caused by such Issuing Lender’s failure to comply with the requirements of the ISP or the Uniform Customs, as applicable, when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof. In furtherance of the foregoing, the parties agree that, with respect to documents presented which appear on their face to be in compliance with the terms of a Letter of Credit, the Issuing Lender that issued such Letter of Credit may, to the extent it is permitted to do so under the ISP or Uniform Customs, as applicable, and otherwise 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 (unless the applicable obligor Borrower shall consent to payment thereon notwithstanding such lack of strict compliance).

3.7 Letter of Credit Payments. Without limitation of Section 3.6, the responsibility of the Issuing Lenders to the Borrowers in connection with any draft presented for payment under any Letter of Credit shall, in addition to any payment obligation expressly provided for in such Letter of Credit, be limited to determining that the documents (including each draft) delivered under such Letter of Credit in connection with such presentment are in conformity with such Letter of Credit.

-29-

3.8 Cash Collateralization of Fronting Exposure. At any time that there shall exist a Defaulting Lender, within five Business Days following the written request of the Administrative Agent or an Issuing Lender, the Borrowers shall Cash Collateralize 105% of the Fronting Exposure (after giving effect to Section 2.5(a)(iv) and any Cash Collateral provided by the Defaulting Lender). Each Borrower, and to the extent provided by a Defaulting Lender, such Defaulting Lender, hereby grants to the Administrative Agent, for the benefit of the Issuing Lenders, a first priority security interest in all such cash, deposit accounts and all balances therein and in all other property so provided as collateral pursuant to this Section 3.8 as security for the obligations for which such Cash Collateral is provided, to be applied as set forth herein. If at any time the Administrative Agent determines that Cash Collateral provided pursuant to this Section 3.8 is less than 105% of the applicable Fronting Exposure secured thereby, the Borrowers will, promptly (but in any event within 5 Business Days) upon demand by the Administrative Agent, pay or provide to the Administrative Agent additional Cash Collateral in an amount sufficient to eliminate such deficiency (after giving effect to any Cash Collateral provided by the Defaulting Lender). Notwithstanding anything to the contrary contained in this Agreement, Cash Collateral provided under this Agreement in respect of Letters of Credit shall be held and applied to the satisfaction of the specific Letter of Credit Outstandings (including, as to Cash Collateral provided by a Defaulting Lender, any interest accrued on such obligation) for which the Cash Collateral was so provided, prior to any other application of such property as may otherwise be provided for herein. Cash Collateral (or the appropriate portion thereof) provided to reduce any Issuing Lender’s Fronting Exposure or other obligations shall be released promptly following (a) the elimination of the applicable Fronting Exposure or payment in full of all other obligations giving rise thereto (including by the termination of Defaulting Lender status of the applicable Lender or, as appropriate, its assignee following compliance with Section 11.6(i)) or (b) the Administrative Agent’s good faith determination that there exists excess Cash Collateral; provided, however, that the Person providing Cash Collateral pursuant to this Section 3.8 and each Issuing Lender may agree that such Cash Collateral shall be held to support future anticipated Fronting Exposure and other obligations and shall remain subject to the security interest granted pursuant to the Loan Documents; and provided further that Cash Collateral furnished by or on behalf of a Borrower pursuant to this Section 3.8 shall not be released during the continuance of an Event of Default.

SECTION 4

(d) Interest shall be payable in arrears on each Interest Payment Date, provided that interest accruing pursuant to Section 4.1(c) shall be payable from time to time on demand.

4.2 Computation of Interest and Fees. (a) Whenever, in the case of ABR Loans, it is calculated on the basis of the Prime Rate, interest shall be calculated on the basis of a 365- (or 366-, as the case may be) day year for the actual days elapsed; and, otherwise, interest and fees shall be calculated on the basis of a 360-day year for the actual days elapsed (including the first day and excluding the last day). The Administrative Agent shall as soon as practicable notify the Borrowers’ Representative and the Lenders of each determination of a Eurodollar Rate. Any change in the interest rate on a Loan resulting from a change in the Alternate Base Rate or the Eurocurrency Reserve Requirements shall become effective as of the opening of business on the day on which such change becomes effective. The Administrative Agent shall as soon as practicable notify the Borrowers’ Representative and the Lenders of the effective date and the amount of each such change in interest rate.

(b) Each determination of an interest rate by the Administrative Agent pursuant to any provision of this Agreement shall be conclusive and binding on the Borrowers and the Lenders in the absence of manifest error. The Administrative Agent shall, at the request of the Borrowers’ Representative, deliver to the Borrowers a statement showing the quotations and calculations used by the Administrative Agent in determining any interest rate pursuant to Sections 4.1(a), (b) and (c).

4.3 Conversion and Continuation Options. (a) The Borrowers may elect from time to time to convert Eurodollar Loans to ABR Loans by having the Borrowers’ Representative give the Administrative Agent at least one Business Day’s prior irrevocable notice of such election, provided that any such conversion of Eurodollar Loans may only be made on the last day of an Interest Period with respect thereto. The Borrowers’ Representative may elect from time to time to convert ABR Loans to Eurodollar Loans by giving the Administrative Agent at least three Business Days’ prior irrevocable notice of such election. Any such notice of conversion to Eurodollar Loans shall specify the length of the initial Interest Period or Interest Periods therefor. Upon receipt of any such notice the Administrative Agent shall promptly notify each Lender thereof. All or any part of outstanding Eurodollar Loans and ABR Loans may be converted as provided herein, provided that (i) no Loan may be converted into a Eurodollar Loan when any Event of Default has occurred and is continuing and the Administrative Agent has or the Required Lenders have determined that such a conversion is not appropriate and (ii) no Loan may be converted into a Eurodollar Loan after the date that is one month prior to the Termination Date.

-31-

4.4 Minimum Amounts Maximum Number of Tranches. All borrowings, conversions and continuations of Loans hereunder and all selections of Interest Periods hereunder shall be in such amounts and be made pursuant to such elections so that, after giving effect thereto, the aggregate principal amount of the Loans comprising each Eurodollar Tranche shall be equal to $5,000,000 or a whole multiple of $1,000,000 in excess thereof. In no event shall there be more than 10 Eurodollar Tranches outstanding at any time.

4.5 Optional Prepayments and Commitment Reductions. (a) The Borrowers may, on the last day of any Interest Period with respect thereto, in the case of Eurodollar Loans, or at any time and from time to time, in the case of ABR Loans, prepay the Loans, in whole or in part, without premium or penalty, upon at least one Business Day’s irrevocable notice to the Administrative Agent in the case of ABR Loans, and upon at least three Business Days’ irrevocable notice to the Administrative Agent in the case of Eurodollar Loans, in each case specifying the date and amount of prepayment and whether the prepayment is of Eurodollar Loans, ABR Loans or a combination thereof, and, in each case if of a combination thereof, the amount allocable to each. Upon receipt of any such notice the Administrative Agent shall promptly notify each Lender thereof. If any such notice is given, the amount specified in such notice shall be due and payable on the date specified therein, together with any amounts payable pursuant to Section 4.14. Partial prepayments of Eurodollar Loans shall be in an aggregate principal amount of $5,000,000 or a whole multiple of $1,000,000 in excess thereof.

(b) Subject to Section 4.5(c), the Borrowers shall have the right, upon not less than three Business Days’ notice to the Administrative Agent, to terminate the Commitments or, from time to time, to reduce the amount of the Commitments. Any such reduction shall be in an amount equal to $5,000,000 or a whole multiple of $1,000,000 in excess thereof and shall reduce permanently the Commitments then in effect. Termination of the Commitments shall also terminate the obligation of the Issuing Lender to issue Letters of Credit.

(c) In the event of the termination by the Borrowers of all Commitments, the Borrowers shall on the date of such termination repay or prepay all of its outstanding Loans (together with accrued and unpaid interest on the Loans and any amounts payable pursuant to Section 4.14 and any other amounts payable hereunder), reduce the Letter of Credit Outstandings to zero and cause all Letters of Credit to be canceled and returned to the Issuing Lender (or shall Cash Collateralize the Letter of Credit Outstandings on terms and pursuant to documentation reasonably satisfactory to the Issuing Lender and the Administrative Agent). In the event of any partial reduction of the Commitments, then (i) at or prior to the effective date of such reduction, the Administrative Agent shall notify the Borrowers’ Representative and the Lenders of the Aggregate Credit Exposure of all the Lenders and (ii) if the Aggregate Credit Exposure of all the Lenders would exceed the aggregate Commitments after giving effect to such reduction, then, prior to giving effect to such reduction, the Borrowers shall, on the date of such reduction, then, repay or prepay Loans and, second, reduce the Letter of Credit Outstandings (or Cash Collateralize the Letter of Credit Outstandings on terms and pursuant to documentation reasonably satisfactory to the Issuing Lender and the Administrative Agent), in an aggregate amount sufficient to eliminate such excess.

-32-

(d) The Loans shall be repaid, and the Letter of Credit Outstandings shall be reduced or Cash Collateralized, to the extent required by Section 4.10. All such prepayments and cash collateralization shall be made in accordance with this Section 4.5.

(e) In the event the amount of any prepayment of the Loans required to be made above shall exceed the aggregate principal amount of the outstanding ABR Loans (the amount of any such excess being called the “Excess Amount”), the Borrowers shall have the right, in lieu of making such prepayment in full, to prepay all the outstanding applicable ABR Loans and to deposit an amount equal to the Excess Amount with, and in the event that Letter of Credit Outstandings are required to be Cash Collateralized, the Borrowers shall deposit an amount equal to the aggregate amount of Letter of Credit Outstandings to be Cash Collateralized with, the Administrative Agent in a cash collateral account maintained (pursuant to documentation reasonably satisfactory to the Administrative Agent) by and in the sole dominion and control of the Administrative Agent. Any amounts so deposited shall be held by the Administrative Agent as collateral for the obligations of the Borrowers under this Agreement and applied to the prepayment of the applicable Eurodollar Loans at the end of the current Interest Periods applicable thereto or Letter of Credit Outstandings, as the case may be, or, during an Event of Default, to payment of any obligations under this Agreement (including obligations in respect of the Letters of Credit). On any Business Day on which (i) collected amounts remain on deposit in or to the credit of such cash collateral account after giving effect to the payments made on such day pursuant to this Section 4.5(e) and (ii) the Borrowers’ Representative shall have delivered to the Administrative Agent a written request or a telephonic request (which shall be promptly confirmed in writing) that such remaining collected amounts be invested in the Cash Equivalent specified in such request, the Administrative Agent shall use its reasonable efforts to invest such remaining collected amounts in such Cash Equivalent, provided, however, that the Administrative Agent shall have continuous dominion and full control over any such investments (and over any interest that accrues thereon) to the same extent that it has dominion and control over such cash collateral account and no Cash Equivalent shall mature after the end of the Interest Period for which it is to be applied. The Borrowers shall not have the right to withdraw any amount from such cash collateral account until the applicable Eurodollar Loans and accrued interest thereon and Letter of Credit Outstandings are paid in full or if a Default or Event of Default then exists or would result. Any prepayment or collateralization pursuant to this Section 4.5(e) shall be applied in the order set forth in clause (ii) of the second sentence of Section 4.5(c).

4.6 Commitment Fee; Administrative Agent’s Fee; Other Fees. (a) The Borrowers agree to pay to the Administrative Agent for the account of each Lender (except for any Defaulting Lender) a commitment fee for the period from and including, for each Lender, the Effective Date to but not including the Termination Date, computed at the Commitment Fee Rate on the average daily amount of the lesser of (i) the Available Commitment of such Lender and (ii) the Borrowing Base Availability with respect to such Lender, during the period for which payment is made, payable quarterly in arrears on the last day of each March, June, September and December (subject to Section 4.8) (commencing on June 30, 2011) and on the Termination Date or such earlier date as the Commitments shall terminate as provided herein, commencing on the first of such dates to occur after the date hereof. Commitment fees shall be nonrefundable when paid unless payment was made in error.

-33-

(b) The Borrowers shall pay to the Administrative Agent the fees set forth in the Administrative Agent Fee Letter.

(c) The Borrowers shall pay to the Lenders (other than any Defaulting Lender) such additional fees as may be agreed to by the Borrowers and the Lenders.

4.7 Inability to Determine Interest Rate. If prior to the first day of any Interest Period:

(a) the Administrative Agent shall have determined (which determination shall be conclusive and binding upon the Borrowers) that, by reason of circumstances affecting the relevant market, adequate and reasonable means do not exist for ascertaining the Eurodollar Rate for such Interest Period, or

(b) the Administrative Agent shall have received notice from the Required Lenders that the Eurodollar Rate determined or to be determined for such Interest Period will not adequately and fairly reflect the cost to such Lenders (as conclusively certified by such Lenders) of making or maintaining their affected Loans during such Interest Period,

the Administrative Agent shall give telecopy or telephonic notice thereof to the Borrowers and the Lenders as soon as practicable thereafter. If such notice is given (x) any Eurodollar Loans requested to be made on the first day of such Interest Period shall be made as ABR Loans, (y) any Loans that were to have been converted on the first day of such Interest Period to Eurodollar Loans shall be continued as ABR Loans and (z) any outstanding Eurodollar Loans shall be converted, on the first day of such Interest Period, to ABR Loans. Until such notice has been withdrawn by the Administrative Agent, no further Eurodollar Loans shall be made or continued as such, nor shall the Borrowers have the right to convert Loans to Eurodollar Loans.

4.8 Pro Rata Treatment and Payments. (a) Each borrowing by the Borrowers from the Lenders hereunder, each payment by the Borrowers on account of any commitment fee hereunder and any reduction of the Commitments of the Lenders shall be made pro rata according to the respective Commitment Percentages of the Lenders. Each payment (including each prepayment) by the Borrowers on account of principal of and interest on the Loans shall be made pro rata according to the respective outstanding principal amounts of the Loans then held by the Lenders. All payments (including prepayments) to be made by the Borrowers hereunder, whether on account of principal, interest, fees or otherwise, shall be made without set off or counterclaim and shall be made prior to 12:00 Noon, New York City time, on the due date thereof to the Administrative Agent, for the account of the Lenders, at the Administrative Agent’s office specified in Section 11.2, in Dollars and in immediately available funds. The Administrative Agent shall distribute such payments to the Lenders promptly upon receipt in like funds as received. If any payment hereunder becomes due and payable on a day other than a Business Day, such payment shall be extended to the next succeeding Business Day, and, with respect to payments of principal, interest thereon shall be payable at the then applicable rate during such extension.

-34-

(b) Unless the Administrative Agent shall have been notified in writing by any Lender prior to a borrowing that such Lender will not make the amount that would constitute its Commitment Percentage of such borrowing available to the Administrative Agent, the Administrative Agent may assume that such Lender is making such amount available to the Administrative Agent, and the Administrative Agent may, in reliance upon such assumption, make available to the Borrowers a corresponding amount. If such amount is not made available to the Administrative Agent by the required time on the Borrowing Date therefor, such Lender shall pay to the Administrative Agent, on demand, such amount with interest thereon at a rate equal to the daily average Federal Funds Effective Rate for the period until such Lender makes such amount immediately available to the Administrative Agent. A certificate of the Administrative Agent submitted to any Lender with respect to any amounts owing under this Section 4.8(b) shall be conclusive in the absence of manifest error. If such Lender’s Commitment Percentage of such borrowing is not made available to the Administrative Agent by such Lender within three Business Days after such Borrowing Date, the Administrative Agent shall also be entitled to recover such amount with interest thereon at the rate per annum applicable to ABR Loans hereunder, on demand, from the Borrowers.

4.9 Computation of Borrowing Base. (a) Borrowing Base. The Borrowing Base in effect from time to time shall represent the maximum principal amount (subject to the aggregate amount of the Commitments) of Loans and Letter of Credit Outstandings that the Lenders will allow to remain outstanding during the Commitment Period. The Borrowing Base will be determined by the Technical Banks in their sole discretion based upon the total assets, cash flow and liabilities of the Borrowers and upon the value of Proved Reserves attributable to the Borrowing Base Properties of the Borrowers determined by the Technical Banks in their sole discretion, and will be determined by the Technical Banks in accordance with paragraph (d) of this Section 4.9, subject to approval by Super Majority Lenders or all of the Lenders, as the case may be. Until the Commitments are no longer in effect, all Letters of Credit have terminated and all of the Loans and all other obligations under this Agreement are paid in full, this Agreement shall be subject to the then effective Borrowing Base.

(b) Reserve Reports. The Borrowers’ Representative shall, at its own expense, furnish to the Administrative Agent and each Lender (i) prior to March 31 of each year, a Reserve Report prepared by the Independent Engineer, dated no earlier than the immediately preceding December 31, (ii) prior to September 30 of each year, a Reserve Report prepared by the engineers employed by the Borrowers dated no earlier than the immediately preceding June 30 and (iii) within 30 days following the delivery of a Borrower Redetermination Notice or a Lender Redetermination Notice, a Reserve Report prepared by the engineers employed by the Borrowers and, if requested by the Required Lenders or the Administrative Agent, within 90 days following the delivery of such notice a Reserve Report prepared by the engineers employed by the Borrowers and audited by the Independent Engineer, in each case certified by a Responsible Officer of the Borrowers’ Representative. If the Borrowers fail to deliver a Reserve Report within the time period provided for, then the Administrative Agent and the Lenders shall have the right to rely on the last Reserve Report previously delivered by the Borrowers with any such adjustments and taking into account any additional information as the Technical Banks may deem appropriate in their sole discretion. Concurrently with the delivery of the Reserve Reports, the Borrowers shall furnish to the Administrative Agent and each Lender a certificate of a Responsible Officer showing any material additions to or material deletions from the Oil and Gas Properties and the Borrowing Base Properties listed in the Reserve Report, which additions or deletions were made by the Borrowers since the date of the previous Reserve Report. Each Technical Bank shall be deemed to have approved each Reserve Report delivered pursuant to this Section 4.9(b) unless such Technical Bank shall have delivered an objection in writing to the Borrowers’ Representative within 15 days of the delivery of such Reserve Report.

-35-

(c) Redetermination of the Borrowing Base. The Technical Banks shall redetermine the Borrowing Base in their sole discretion, and the Administrative Agent shall notify the Borrowers’ Representative and the Lenders of the Technical Banks’ redetermination of the Borrowing Base (i) with respect to regularly scheduled Reserve Reports, (A) on or before April 30 (in the case of Reserve Reports due on March 31) and (B) on or before October 31 (in the case of Reserve Reports due on September 30), and (ii) with respect to a Lender Redetermination Notice or a Borrower Redetermination Notice, as promptly as practicable following delivery to the Administrative Agent of all information (including Reserve Reports) requested from the Borrowers, or if no such information is delivered by Borrowers following such request, then at such time as the Administrative Agent determines is practicable but, in any case, no later than 30 days after delivery of such information or, if such information is not timely delivered, 30 days after the date such information was required to be delivered. Within 15 days after receipt from the Administrative Agent of the amount of a redetermination of the Borrowing Base, each Lender shall notify the Administrative Agent in writing stating whether or not such Lender agrees with that redetermination. Failure of any Lender to give such notice within such period of time shall not be deemed to constitute an acceptance of such redetermination. The Borrowing Base may be decreased from the then effective Borrowing Base with the consent of the Super Majority Lenders but may only be increased from the then effective Borrowing Base with the consent of all of the Lenders. If the Super Majority Lenders or all of the Lenders, as the case may be, agree with that redetermination, then the Administrative Agent promptly shall notify the Borrowers’ Representative of the Borrowing Base as so redetermined. Redeterminations made in connection with regularly scheduled Reserve Reports shall become effective (and shall remain effective until the Borrowing Base is again redetermined as provided in this subsection (c)) on May 15 (in the case of Reserve Reports due on March 31) and November 15 (in the case of Reserve Reports due on September 30), and other redeterminations shall become effective upon written notice from the Administrative Agent to the Borrowers’ Representative and the Lenders of the redetermined Borrowing Base. If Super Majority Lenders or all of the Lenders, as the case may be, have not approved in writing the Borrowing Base within the 15 day period following their receipt of the proposed amount from the Administrative Agent, the Borrowing Base shall be set at the amount of the then current Borrowing Base and the Borrowing Base shall remain at such level until Super Majority Lenders or all of the Lenders, as the case may be, utilizing the procedure outlined herein, agree on a new Borrowing Base and the Administrative Agent shall give notice thereof to the Borrowers. Each redetermination provided for by this Section 4.9(c) shall be made in accordance with the provisions of Section 4.9(d).

-36-

(d) Criteria. All determinations and redeterminations by the Technical Banks provided for in this Section 4.9 (and any determinations and decisions by either or both of the Technical Banks and Super Majority Lenders or all of the Lenders, as the case may be, in connection therewith, including effecting any redetermination of the value of any component contained in a Reserve Report) shall be made by the Technical Banks and the Lenders in their sole discretion based upon the application by the Technical Banks and the Lenders of their respective oil and gas lending criteria as they customarily use at the time of determination in assigning collateral value to oil and gas properties for similarly situated customers of the Technical Banks and the Lenders and using, when determining such value, any hedging that may be allocated to the Oil and Gas Properties in the Borrowing Base.

(e) Subordinated Indebtedness. At least thirty (30) days prior to the incurrence of Subordinated Indebtedness, the Borrower which proposes to incur such Subordinated Indebtedness shall so notify the Administrative Agent. Following the receipt of such notice the Required Banks shall have the right to serve a Lender Redetermination Notice on the Borrowers’ Representative, which Lender Redetermination Notice shall not count towards the maximum number of such Notices which the Required Lenders may otherwise serve between Scheduled Redetermination Dates.

(f) Mandatory Reductions. Following the Disposition of any Borrowing Base Property pursuant to Section 8.6(d) for consideration with a value in excess of $50,000,000.00 (a “Specified Disposition”), the Borrowing Base shall be redetermined (by reference to the most recent Reserve Report) taking into account the PV-10 Value of the Properties remaining in the Borrowing Base, unless such Borrowing Base Property is contemporaneously replaced by a Borrower with substitute Borrowing Base Property with a PV-10 Value reasonably acceptable to the Technical Banks or, pending delivery of such Borrowing Base Property, with Cash Collateral equal to or greater than such PV-10 Value. The Borrowers’ Representative shall provide at least 5 Business Days’ advance written notice to the Technical Banks of any Specified Disposition.

(g) Initial Borrowing Base. The initial Borrowing Base hereunder shall be $1,000,000,000.00.

4.10 Mandatory Prepayments.

(a) Borrowing Base Deficiency. Upon the occurrence of a Borrowing Base Deficiency, the Administrative Agent shall notify the Borrowers’ Representative of such Borrowing Base Deficiency. Within 20 days from and after the Borrowing Base Deficiency Notification Date, the Borrowers’ Representative shall notify the Administrative Agent that the Borrowers elect to take one of the following actions:

(i) Execute and deliver to the Administrative Agent supplemental or additional Security Documents, in form and substance reasonably satisfactory to the Administrative Agent and its counsel, securing payment of the Notes and the other Obligations and covering additional Hydrocarbon Interests directly owned by any Borrower which are not then designated as Borrowing Base Properties and which are of a type and nature, and having a value (determined by the Administrative Agent in its sole discretion using the standards applicable to a Borrowing Base redetermination), in addition to other Borrowing Base Properties reasonably satisfactory to the Administrative Agent and the Required Lenders, sufficient to eliminate the Borrowing Base Deficiency;

-37-

(ii) Make a payment with respect to the Obligations (which shall be applied, or held for application, as the case may be, by the Administrative Agent to the payment of the aggregate unpaid principal amount of those Loans then outstanding and then Letter of Credit Outstandings) in an aggregate principal amount sufficient to eliminate such Borrowing Base Deficiency within thirty (30) days after the Borrowing Base Deficiency Notification Date;

(iii) Execute and deliver additional Security Documents, as provided in clause (i) above, sufficient to eliminate a portion of the Borrowing Base Deficiency and make a payment as provided in clause (ii) above in an aggregate principal amount sufficient to eliminate the balance of the Borrowing Base Deficiency; or

(iv) Make six (6) consecutive prepayments of principal of the outstanding Loans, each of which shall be in an amount equal to 1/6th of the amount of the Borrowing Base Deficiency, commencing on the first Monthly Date following delivery of the notice of Borrower’s election, and continuing on (or, at the Borrowers’ option, before) each Monthly Date thereafter until such Deficiency has been eliminated by such prepayments, addition of properties to the Borrowing Base Properties or a combination of the foregoing.

(b) Security Documents. If the Borrowers elect to execute and deliver supplemental or additional Security Documents to the Administrative Agent pursuant to Section 4.10(a)(i) or (a)(iii) above, it shall provide the Administrative Agent and each Lender with descriptions of the additional assets to be collaterally assigned (together with current valuations satisfactory to the Technical Banks or engineering reports as to the new Properties, Security Documents, and, if necessary to comply with the Continuing 70% Test, title evidence applicable thereto, each of which shall be in form and substance reasonably satisfactory to the Administrative Agent), within twenty (20) days after the Borrowing Base Deficiency Notification Date, except that title evidence may be furnished within ninety (90) days after such Date. If the Borrowers’ Representative fails to take any of the actions described above within the relevant period, then without any necessity for notice to the Borrowers or any other person, the Borrowers shall become obligated to pay Obligations in an aggregate principal amount equal to the applicable Borrowing Base Deficiency within three (3) days after the end of the relevant period.

4.11 Illegality. Notwithstanding any other provision herein, if the adoption of or any change in any Requirement of Law or in the interpretation or application thereof after the date hereof shall make it unlawful for any Lender to make or maintain Eurodollar Loans as contemplated by this Agreement (a) the commitment of such Lender hereunder to make Eurodollar Loans, continue Eurodollar Loans as such and convert ABR Loans to Eurodollar Loans shall forthwith be canceled and (b) such Lender’s Loans then outstanding as Eurodollar Loans, if any, shall be converted automatically to ABR Loans on the respective last days of the then current Interest Periods with respect to such Loans or within such earlier period as required by law. If any such conversion of a Eurodollar Loan occurs on a day which is not the last day of the then current Interest Period with respect thereto, the Borrowers shall pay to such Lender such amounts, if any, as may be required pursuant to Section 4.14.

-38-

4.12 Requirements of Law. (a) If the adoption of or any change in any Requirement of Law or in the interpretation or application thereof after the date hereof or compliance by any Lender with any request or directive (whether or not having the force of law) from any central bank or other Governmental Authority made subsequent to the date hereof:

(i) shall subject any Lender to any tax of any kind whatsoever with respect to this Agreement, any Note, any Letter of Credit, any letter of credit application or any Eurodollar Loan made by it, or change the basis of taxation of payments to such Lender in respect thereof (except for Non-Excluded Taxes covered by Section 4.13, changes in the rate or computation of tax on the overall net income of such Lender, franchise taxes imposed in lieu of net income taxes and doing business taxes);

(ii) shall impose, modify or hold applicable any reserve, special deposit, compulsory loan or similar requirement against assets held by, deposits or other liabilities in or for the account of, advances, loans or other extensions of credit by, or any other acquisition of funds by, any office of such Lender which is not otherwise included in the determination of the Eurodollar Rate hereunder, or

(iii) shall impose on such Lender any other condition;

and the result of any of the foregoing is to increase the cost to such Lender, by an amount which such Lender deems to be material, of making, converting into, continuing or maintaining Eurodollar Loans or issuing or participating in Letters of Credit or to reduce any amount receivable hereunder in respect thereof, then, in any such case, the Borrowers shall promptly pay such Lender such additional amount or amounts as will compensate such Lender for such increased cost or reduced amount receivable.

(b) If any Lender shall have determined that the adoption of or any change in any Requirement of Law regarding capital adequacy or in the interpretation or application thereof or compliance by such Lender or any corporation controlling such Lender with any request or directive regarding capital adequacy (whether or not having the force of law) from any Governmental Authority made subsequent to the date hereof shall have the effect of reducing the rate of return on such Lender’s or such corporation’s capital as a consequence of its obligations hereunder or under any Letter of Credit to a level below that which such Lender or such corporation could have achieved but for such adoption, change or compliance (taking into consideration such Lender’s or such corporation’s policies with respect to capital adequacy) by an amount deemed by such Lender to be material, then from time to time, the Borrowers shall promptly pay to such Lender such additional amount or amounts as will compensate such Lender for such reduction.

(c) If any Lender becomes entitled to claim any additional amounts pursuant to this Section 4.12, it shall promptly notify the Borrowers’ Representative (with a copy to the Administrative Agent) of the event by reason of which it has become so entitled. A certificate as to any additional amounts payable pursuant to this Section 4.12 submitted by such Lender to the Borrowers’ Representative (with a copy to the Administrative Agent) shall be conclusive in the absence of manifest error. The agreements in this Section 4.12 shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder.

-39-

(d) For purposes of this Section 4.12, (i) the Dodd-Frank Wall Street Reform and Consumer Protection Act and all requests, rules, requirements, guidelines and directives thereunder, issued in connection therewith or in implementation thereof and (ii) all requests, rules, requirements, guidelines and directives promulgated by the Bank for International Settlements, the Basel Committee or Banking Supervision (or any successor or similar authority) or the United States or foreign regulatory authorities, in each case pursuant to Basel III, shall in each case be deemed to be a change in a Requirement of Law regardless of the date enacted, adopted, issued or implemented.

4.13 Taxes. (a) All payments made by the Borrowers under this Agreement and any Notes shall be made free and clear of, and without deduction or withholding for or on account of, any present or future income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now or hereafter imposed, levied, collected, withheld or assessed by any Governmental Authority, excluding net income taxes (including taxes imposed under FATCA), franchise taxes (imposed in lieu of net income taxes) and doing business taxes imposed on the Administrative Agent or any Lender as a result of a present or former connection between the Administrative Agent or such Lender and the jurisdiction of the Governmental Authority imposing such tax or any political subdivision or taxing authority thereof or therein (other than any such connection arising solely from the Administrative Agent or such Lender having executed, delivered or performed its obligations or received a payment under, or enforced, this Agreement or any Note). If any such non-excluded taxes, levies, imposts, duties, charges, fees, deductions or withholdings (“Non-Excluded Taxes”) are required to be withheld from any amounts payable to the Administrative Agent or any Lender hereunder or under any Note, the amounts so payable to the Administrative Agent or such Lender shall be increased to the extent necessary to yield to the Administrative Agent or such Lender (after payment of all Non-Excluded Taxes) interest or any such other amounts payable hereunder at the rates or in the amounts specified in this Agreement, provided, however, that the Borrowers shall not be required to increase any such amounts payable to any Non-U.S. Lender if such Non-U.S. Lender fails to comply with the requirements of paragraph (b) of this Section 4.13. Whenever any Non-Excluded Taxes are payable by the Borrowers, as promptly as possible thereafter the Borrowers shall send to the Administrative Agent for their own account or for the account of such Lender, as the case may be, a certified copy of an original official receipt received by the Borrowers showing payment thereof. If, when the Borrowers are required by this Section 4.13(a) to pay any Non-Excluded Taxes, the Borrowers fail to pay any Non-Excluded Taxes when due to the appropriate taxing authority or fail to remit to the Administrative Agent the required receipts or other required documentary evidence, the Borrowers shall indemnify the Administrative Agent and the Lenders for any incremental taxes, interest or penalties that may become payable by the Administrative Agent or any Lender as a result of any such failure. The agreements in this Section 4.13 shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder.

-40-

(b) Each Lender (or Transferee) that is not a citizen or resident of the United States of America, a corporation, partnership or other entity created or organized in or under the laws of the United States of America, or any estate or trust that is subject to federal income taxation regardless of the source of its income (a “Non-U.S. Lender”) shall deliver to the Borrowers’ Representative and the Administrative Agent (or, in the case of a Participant, to the Lender from which the related participation shall have been purchased) (i) two copies of either U.S. Internal Revenue Service Form W-8BEN, Form W-8ECI or successors forms, and is otherwise exempt from IRS interest withholding obligations or (ii) in the case of a Non-U.S. Lender claiming exemption from U.S. federal withholding tax under Section 871(h) or 881(c) of the Code with respect to payments of “portfolio interest,” a Form W-8, or any subsequent versions thereof or successors thereto (and, if such Non-U.S. Lender delivers a Form W-8, an annual certificate representing that such Non-U.S. Lender (x) is not a “bank” for purposes of Section 881(c) of the Code (and is not subject to regulatory or other legal requirements as a bank in any jurisdiction, and has not been treated as a bank in any filing with or submission made to any Governmental Authority or rating agency), (y) is not a 10% shareholder (within the meaning of Section 871(h)(3)(B) of the Code) of the Borrowers and (z) is not a controlled foreign corporation related to the Borrowers (within the meaning of Section 864(d)(4) of the Code)) or (iii) if a payment made to a Lender under any Loan Document would be subject to U.S. federal withholding imposed by FATCA (provided that, solely for purposes of this Section 4.13(b), FATCA shall include any amendments made to FATCA after the date of this Agreement) if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code), properly completed and duly executed by such Non-U.S. Lender claiming complete exemption from U.S. federal withholding tax on all payments by the Borrowers under this Agreement and the other Loan Documents, along with such other additional forms as the Borrowers, the Administrative Agent (or, in the case of a Participant, the Lender from which the related participation shall have been purchased) may reasonably request to establish the availability of such exemption. Such forms shall be delivered by each Non-U.S. Lender on or before the date it becomes a party to this Agreement (or, in the case of any Participant, on or before the date such Participant purchases the related participation), and if a Person cannot deliver such forms because such Person is not exempt from U.S. federal withholding tax under the Code as described above, then such Person shall not become a Lender or Transferee hereunder or a party hereto.

4.14 Indemnity. The Borrowers agree to indemnify each Lender and to hold each Lender harmless from any loss or expense which such Lender may sustain or incur IN ALL CASES, WHETHER OR NOT CAUSED BY OR ARISING, IN WHOLE OR IN PART, OUT OF THE COMPARATIVE, CONTRIBUTORY OR SOLE NEGLIGENCE OF THE ISSUING LENDER (other than through such Lender’s gross negligence or willful misconduct) as a consequence of (a) default by the Borrowers in making a borrowing of, conversion into or continuation of Eurodollar Loans after the Borrowers’ Representative has given a notice requesting the same in accordance with the provisions of this Agreement, (b) default by the Borrowers in making any prepayment of a Eurodollar Loan after the Borrowers’ Representative has given a notice thereof in accordance with the provisions of this Agreement or (c) the making of a prepayment of or a conversion of Eurodollar Loans on a day which is not the last day of an Interest Period with respect thereto. Such indemnification may include an amount equal to the excess, if any, of (i) the amount of interest which would have accrued on the amount so prepaid, or converted, or not so borrowed, converted or continued, for the period from the date of such prepayment or conversion or of such failure to borrow, convert or continue to the last day of the applicable Interest Period (or, in the case of a failure to borrow, convert or continue, the Interest Period that would have commenced on the date of such failure) in each case at the applicable rate of interest for such Eurodollar Loans provided for herein (excluding, however, the percentage added to the Eurodollar Rate pursuant to Section 4.1 (a) to the extent included therein) over (ii) the amount of interest (as reasonably determined by such Lender) which would have accrued to such Lender on such amount by placing such amount on deposit for a comparable period with leading banks in the interbank eurodollar market. This covenant shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder.

-41-

4.15 Change of Lending Office. Each Lender agrees that if it makes any demand for payment under Section 4.12 or 4.13(a), or if any adoption or change of the type described in Section 4.11 shall occur with respect to it, it will use reasonable efforts (consistent with its internal policy and legal and regulatory restrictions and so long as such efforts would not be disadvantageous to it, as determined in its sole discretion) to designate a different lending office if the making of such a designation would reduce or obviate the need for the Borrowers to make payments under Section 4.12 or 4.13(a), or would eliminate or reduce the effect of any adoption or change described in Section 4.11.

4.16 Collateral Security.

(a) Mortgages. To secure the performance by the Borrowers of the Obligations hereunder and under the Notes, the Security Documents and any Secured Hedging Agreement, whether now or hereafter incurred, matured or unmatured, direct or contingent, including extensions, modifications, renewals and increases thereof, and substitutions therefore, the Borrowers shall, on or before June 15, 2011, have, pursuant to the Mortgages, granted and assigned to the Administrative Agent, for the ratable benefit of the Secured Parties, a first priority Lien, subject only to Permitted Liens, on Borrowing Base Properties representing 95% of the PV-10 Value of the Borrowing Base Properties.

(b) Form of Security Documents. The granting and assigning of such security interests and Liens by the Borrowers shall be pursuant to the Security Documents in form and substance reasonably satisfactory to the Administrative Agent.

(c) Title Work. Borrowers are not required to deliver new or updated title opinions for Borrowing Base Properties that have been previously delivered to the Lenders on the existing Borrowing Base. Within 120 days after the Effective Date, the Borrowers shall have furnished to the Administrative Agent title documents, including those previously delivered on the existing Borrowing Base Properties, reasonably satisfactory to the Administrative Agent, with respect to the title and Lien status of at least 60% of the PV-10 Value of the Borrowing Base Properties, and, within 180 days after the Effective Date, the Borrowers shall have furnished to the Administrative Agent title documents, including those previously delivered on the existing Borrowing Base Properties, reasonably satisfactory to the Administrative Agent, with respect to the title and Lien status of at least 70% of the PV-10 Value of the Borrowing Base Properties. Thereafter, the Borrowers shall furnish to the Administrative Agent title documents reasonably satisfactory to the Administrative Agent with respect to the title and Lien status of a sufficient number of Properties so that the Administrative Agent shall at all times have title documents with respect to at least 70% of the PV-10 Value of the Borrowing Base Properties of the Borrowers (the “Continuing 70% Test”). If at any time after the 180th day after the Effective Date, the Borrowers fail to provide title documents reasonably satisfactory to the Administrative Agent for a sufficient number of Borrowing Base Properties to meet the Continuing 70% Test, such failure shall not constitute an Event of Default, but the Technical Banks may redetermine the Borrowing Base by written notice to the Borrowers’ Representative as required to bring the Borrowers into compliance with the Continuing 70% Test until such title documents are provided. Without regard to whether the Borrowers provide satisfactory title documents with respect to a particular Oil and Gas Property owned by such Person, such Oil and Gas Property shall, if necessary to meet the requirements of Section 7.9 hereof, be encumbered by a Mortgage in favor of the Administrative Agent for the ratable benefit of the Secured Parties, and shall be included in the collateral.

-42-

(d) Security for Hedge Parties. The Administrative Agent and the Lenders agree that upon execution and delivery of a Hedging Agreement by a Hedge Party, such Hedge Party shall possess a pari passu Lien in the collateral provided in the Security Documents and the cash proceeds therefrom as security for the obligations of the Borrowers under such Hedging Agreement.

(e) Substitution of Collateral. The Borrowers shall have the right, subject to the consent of the Technical Banks, such consent not to be unreasonably withheld, to substitute Oil and Gas Properties of a Borrower for Oil and Gas Properties subject to a Mortgage, or, pending delivery of the Mortgage on such Properties, to substitute Cash Collateral for such Properties, provided that:

(i) The Borrowers’ Representative provides notice of substitution to the Administrative Agent fifteen (15) days prior to the proposed substitution date;

(ii) Neither an Event of Default nor a Borrowing Base Deficiency exists on the proposed substitution date;

(iii) The Oil and Gas Properties proposed to be substituted for the Oil and Gas Properties subject to a Mortgage are either (A) of a type and nature similar to the Oil and Gas Properties subject to a Mortgage or (B) are consented to by the Technical Banks, such consent not to be unreasonably withheld;

(iv) The substitution of the Oil and Gas Properties will not result in a decrease in the Borrowing Base as determined by the Technical Banks in their sole discretion; and

(v) The Borrowers provide the supplemental or additional Security Documents referred to in Section 4.10(b) hereof.

If the Oil and Gas Properties being substituted have a value in excess of 15% of the PV-10 Value of the Borrowing Base Properties at such time, the Borrowing Base shall be redetermined prior to the date of such substitution in accordance with the procedures set forth in Section 4.9 which would have applied had a Borrower Redetermination Notice or a Lender Redetermination Notice been delivered.

-43-

(f) If the conditions set forth in Section 4.16(e) have been satisfied, then upon request by EPEP, the Administrative Agent will release its lien on any Borrowing Base Property being exchanged for other Borrowing Base Property pursuant to Section 4.16(e).

4.17 Replacement of Lenders. If (i) any Lender requests compensation under Section 4.12, or (ii) if any Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 4.13, or (iii) if any Lender is a Defaulting Lender or (iv) any Lender refuses to grant its approval with respect to any matter requiring the approval of all Lenders or any increases to the Borrowing Base and such matter or increase to the Borrowing Base shall have been approved by Lenders having Commitments in excess of 50% of the aggregate Commitments, then the Borrowers’ Representative may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 11.6), all its interests, rights and obligations under this Agreement to an assignee identified by the Borrowers’ Representative (other than a Borrower or any Subsidiary of a Borrower) that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (1) the Borrowers’ Representative shall have received the prior written consent of the Administrative Agent, which consent shall not unreasonably be withheld, (2) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrowers (in the case of all other amounts) and (3) in the case of any such assignment resulting from a claim for compensation under Section 4.12 or payments required to be made pursuant to Section 4.13, 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 Borrowers’ Representative to require such assignment and delegation cease to apply.

SECTION 5

Each of the Borrowers (a) is duly formed, validly existing and in good standing under the laws of the jurisdiction of its formation, (b) has the power and authority, and the legal right, to own and operate its Property, to lease the Property it operates as lessee and to conduct the business in which it is currently engaged, (c) is duly qualified as a foreign entity and in good standing under the laws of each jurisdiction where its ownership, lease or operation of Property or the conduct of its business requires such qualification except to the extent that the failure to be so qualified and in good standing could not reasonably be expected to have, in the aggregate, a Material Adverse Effect and (d) is in compliance with all applicable Requirements of Law (including, without limitation, Environmental Laws) except to the extent that the failure to comply therewith could not reasonably be expected to have, in the aggregate, a Material Adverse Effect.

5.4 Corporate Power; Authorization; Enforceable Obligations. Each Borrower has the power and authority, and the legal right, to make, deliver and perform the Loan Documents to which it is a party and to borrow hereunder and has taken all necessary action to authorize the execution, delivery and performance of the Loan Documents to which it is a party. No consent or authorization of, filing with, notice to or other act by or in respect of, any Governmental Authority or any other Person is required in connection with the borrowings hereunder or the delivery, performance, validity or enforceability of the Loan Documents to which any Borrower is a party other than the filings of the Mortgages and UCC-1 financing statements and those which have been obtained and are in full force and effect.

5.5 No Legal Bar. The execution, delivery and performance of the Loan Documents, the granting of the Liens under the Security Documents, the borrowings hereunder and the use of the proceeds thereof will not violate any applicable Requirement of Law or Contractual Obligation of the Borrowers and will not result in, or require, the creation or imposition of any Lien on any of its or their respective Properties or revenues pursuant to any such Requirement of Law or Contractual Obligation, other than any Lien created pursuant to the Security Documents.

-45-

5.6 No Material Litigation. No litigation, investigation or proceeding of or before any arbitrator or Governmental Authority is pending or, to the knowledge of any Borrower, threatened by or against any Borrower or against any of its respective Properties or revenues (a) with respect to any of the Loan Documents or any of the transactions contemplated hereby or thereby, or (b) which could reasonably be expected to have a Material Adverse Effect.

There are no “back-in” or “reversionary” interests held by third parties which could materially reduce the interest of the Borrowers in such Borrowing Base Properties except as expressly set forth in such Reserve Report. The ownership of the Borrowing Base Properties by the Borrowers shall not in any material respect obligate any Borrower to bear the costs and expenses relating to the maintenance, development or operations of each such Borrowing Base Property in an amount in excess of the working interest of such Borrower in each Borrowing Base Property set forth in the most recent Reserve Report unless there is a corresponding increase in net revenue interest.

5.9 [Reserved].

5.10 Taxes. Each Borrower has filed all material tax returns which, to the knowledge of such Borrower, are required to be filed by it and has paid or caused to be paid all taxes shown on said returns and all assessments, fees and other governmental charges levied upon it or upon any of its Property or income which are due and payable, other than such taxes, assessments, fees and other governmental charges, if any, as are being diligently contested in good faith and by appropriate proceedings and with respect to which there have been established adequate reserves on the books of the Borrowers in accordance with GAAP.

The Loans and other transactions contemplated hereunder will not violate the provisions of Regulations T and X.

-46-

(d) Neither EPEP nor any nor any ERISA Affiliate has incurred, or is reasonably expected to incur, any Withdrawal Liability to any Multiemployer Plan which, when aggregated with all other amounts required to be paid to Multiemployer Plans in connection with Withdrawal Liability (as of the date of determination), would have a Material Adverse Effect.

5.13 Investment Company Act; Other Regulations. No Borrower is an “investment company,” or a company “controlled” by an “investment company,” within the meaning of the Investment Company Act of 1940, as amended.

third, to pay the unpaid principal of all Loans, all unreimbursed L/C Disbursements, to Cash Collateralize all outstanding Letters of Credit and to pay Obligations due and payable under each Secured Hedging Agreement, all ratably until the principal of all Loans, all unreimbursed L/C Disbursements and all Obligations due and payable under Secured Hedging Agreements shall have been paid in full and all Letters of Credit shall have been Cash Collateralized;

fourth, to pay all other Obligations ratably, until payment in full of all such other Obligations shall have been made; and

fifth, to pay to the applicable Borrower any surplus then remaining from amounts received from it or the proceeds of the collateral owned by it or, in either case, as a court of competent jurisdiction may direct.

The Administrative Agent may make such distributions in cash or in kind or, on a ratable basis, in any combination thereof.

9.3 Cash Collateral. With respect to all Letters of Credit with respect to which presentment for honor shall not have occurred at the time of an acceleration pursuant to the preceding paragraph, the Borrowers shall at such time deposit in a cash collateral account opened by the Administrative Agent an amount equal to the aggregate then unexpired amount that is available to be drawn under such Letters of Credit. The Borrowers hereby grant to the Administrative Agent, for the benefit of the Issuing Lender and the L/C Participants, a security interest in such cash collateral to secure all obligations of the Borrowers under this Agreement and the other Loan Documents. Amounts held in such cash collateral account shall be applied by the Administrative Agent to the payment of drafts drawn under such Letters of Credit, and the unused portion thereof after all such Letters of Credit shall have expired, been cancelled or been fully drawn upon, if any, shall be applied to repay other obligations of the Borrowers hereunder and under the Notes. After all such Letters of Credit shall have expired, been cancelled or been fully drawn upon, all Reimbursement Obligations shall have been satisfied and all other obligations of the Borrowers hereunder and under the other Loan Documents shall have been paid in full, the balance, if any, in such cash collateral account shall be returned to the Borrowers. The Borrowers shall execute and deliver to the Administrative Agent, for the account of the Issuing Lender and the L/C Participants, such further documents and instruments as the Administrative Agent may reasonably request to evidence the creation and perfection of the within security interest in such cash collateral account. Except as expressly provided above in this Section, presentment, demand, protest and all other notices of any kind are hereby expressly waived.

SECTION 10

THE ADMINISTRATIVE AGENT

10.1 Appointment. Each Lender hereby irrevocably designates and appoints BNPP as Administrative Agent of such Lender under this Agreement and the other Loan Documents, and each such Lender irrevocably authorizes the Administrative Agent, in such capacity, to take such action on its behalf under the provisions of this Agreement and the other Loan Documents and to exercise such powers and perform such duties as are expressly delegated to the Administrative Agent by the terms of this Agreement and the other Loan Documents, together with such other powers as are reasonably incidental thereto. Notwithstanding any provision to the contrary contained elsewhere in this Agreement, the Administrative Agent shall not have any duties or responsibilities, except those expressly set forth herein, or any fiduciary relationship with any Lender, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into this Agreement or any other Loan Document or otherwise exist against the Administrative Agent.

-66-

10.2 Delegation of Duties. The Administrative Agent may execute any of its duties under this Agreement and the other Loan Documents by or through agents or attorneys-in-fact and shall be entitled to advice of counsel concerning all matters pertaining to such duties. The Administrative Agent shall not be responsible for the negligence or misconduct of any agents or attorneys-in-fact selected by it with reasonable care.

10.3 Exculpatory Provisions. None of the Technical Banks nor any of their respective officers, directors, employees, agents, attorneys-in-fact or Affiliates shall be (i) liable for any action lawfully taken or omitted to be taken by it or such Person under or in connection with this Agreement or any other Loan Document (except for its or such Person’s own gross negligence or willful misconduct) or (ii) responsible in any manner to any of the Lenders for any recitals, statements, representations or warranties made by either Borrower or any Restricted Subsidiary or any officer thereof contained in this Agreement or any other Loan Document or in any certificate, report, statement or other document referred to or provided for in, or received by the Administrative Agent under or in connection with, this Agreement or any other Loan Document or for the value, validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other Loan Document or for any failure of either Borrower or any Restricted Subsidiary to perform its obligations hereunder or thereunder. The Administrative Agent shall not be under any obligation to any Lender to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Agreement or any other Loan Document, or to inspect the properties, books or records of either Borrower or any Restricted Subsidiary.

10.4 Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely, and shall be fully protected in relying, upon any Note, writing, resolution, notice, consent, certificate, affidavit, letter, telecopy, telex or teletype message, statement, order or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons and upon advice and statements of legal counsel (including, without limitation, counsel to either Borrower or any Restricted Subsidiary), independent accountants and other experts selected by the Administrative Agent. The Administrative Agent may deem and treat the payee of any Note as the owner thereof for all purposes unless a written notice of assignment, negotiation or transfer thereof shall have been filed with the Administrative Agent. The Administrative Agent shall be fully justified in failing or refusing to take any action under this Agreement or any other Loan Document unless it shall first receive such advice or concurrence of the Required Lenders (or, where unanimous consent of the Lenders is expressly required hereunder, such Lenders) as it deems appropriate or it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. The Administrative Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement and the other Loan Documents in accordance with a request of the Required Lenders (or, where unanimous consent of the Lenders or the Required Lenders is expressly required hereunder, such Lenders or Required Lenders, as applicable), and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders and all future holders of the Loans. The Administrative Agent shall not be required to take any action that, in its opinion or the opinion of its counsel, may expose the Administrative Agent to liability or that is contrary to any Loan Document or applicable law, including for the avoidance of doubt any action that may be in violation of the automatic stay under any Debtor Relief Law or that may effect a forfeiture, modification or termination of property of a Defaulting Lender in violation of any Debtor Relief Law.

-67-

10.5 Notice of Default. The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default hereunder unless the Administrative Agent has received notice from a Lender or a Borrower referring to this Agreement, describing such Default or Event of Default and stating that such notice is a “notice of default.” In the event that the Administrative Agent receives such a notice, the Administrative Agent shall promptly give notice thereof to the Lenders. The Administrative Agent shall take such action with respect to such Default or Event of Default as shall be reasonably directed by the Required Lenders; 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 or Event of Default as it shall deem advisable in the best interests of the Lenders.

10.6 Non-Reliance on Administrative Agent and Other Lenders. Each Lender expressly acknowledges that neither the Administrative Agent nor any of its officers, directors, employees, agents, attorneys-in-fact or Affiliates has made any representations or warranties to it and that no act by the Administrative Agent hereafter taken, including any review of the affairs of either Borrower, shall be deemed to constitute any representation or warranty by the Administrative Agent to any Lender. Each Lender represents to the Administrative Agent that it has, independently and without reliance upon the Administrative Agent or any other Lender, and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, operations, property, financial and other condition and creditworthiness of each Borrower and made its own decision to make its Extensions of Credit hereunder and enter into this Agreement. Each Lender also represents that it will, independently and without reliance upon the Administrative Agent or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Loan Documents, and to make such investigation as it deems necessary to inform itself as to the business, operations, property, financial and other condition and creditworthiness of each Borrower. Except for notices, reports and other documents expressly required to be furnished to the Lenders by the Administrative Agent hereunder, the Administrative Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the business, operations, property, condition (financial or otherwise), prospects or creditworthiness of either Borrower which may come into the possession of the Administrative Agent or any of its officers, directors, employees, agents, attorneys-in-fact or Affiliates.

-68-

10.7 Indemnification. The Lenders agree to indemnify the Administrative Agent in its capacity as such (to the extent not reimbursed by the Borrowers and without limiting the obligation the Borrowers to do so), ratably according to their respective Commitment Percentages in effect on the date on which indemnification is sought, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever which may at any time (including, without limitation, at any time following the payment of the obligations under this Agreement) be imposed on, incurred by or asserted against the Administrative Agent in any way relating to or arising out of, the Commitments, this Agreement, any of the other Loan Documents or any documents contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby or any action taken or omitted by the Administrative Agent under or in connection with any of the foregoing; provided that no Lender shall be liable for the payment of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting solely from the Administrative Agent’s gross negligence or willful misconduct. The agreements in this Section 10.7 shall survive the payment of all obligations under this Agreement and all other amounts payable hereunder.

10.8 Administrative Agent in Its Individual Capacity. The Administrative Agent and its Affiliates may make loans to, accept deposits from and generally engage in any kind of business with either Borrower or any Restricted Subsidiary as though the Administrative Agent were not the Administrative Agent hereunder and under the other Loan Documents. With respect to the Extensions of Credit made by it, the Administrative Agent shall have the same rights and powers under this Agreement and the other Loan Documents as any Lender and may exercise the same as though it were not the Administrative Agent, and the terms “Lender” and “Lenders” shall include the Administrative Agent in its individual capacity.

10.9 Successor Administrative Agent. The Administrative Agent may resign as Administrative Agent upon 30 days’ notice to the Lenders. If the Administrative Agent shall resign as Administrative Agent under this Agreement and the other Loan Documents, then the Required Lenders shall appoint from among the Lenders a successor agent for the Lenders, which successor agent, with the consent of the Borrowers (such consent not to be unreasonably withheld or delayed), shall succeed to the rights, powers and duties of the Administrative Agent hereunder. Effective upon such appointment and approval, the term “Administrative Agent” shall mean such successor agent, and the former Administrative Agent’s rights, powers and duties as Administrative Agent shall be terminated, without any other or further act or deed on the part of such former Administrative Agent or any of the parties to this Agreement or any holders of the Loans. After any retiring Administrative Agent’s resignation as Administrative Agent, the provisions of this Section 10 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under this Agreement and the other Loan Documents. The Administrative Agent may be removed at any time with or without cause by the Required Lenders (which for this purpose, shall not include the Loans or Commitments of the Administrative Agent), provided that on the effectiveness of such removal the Obligations owing to such Administrative Agent as a Lender are repaid in full and as an Issuing Lender are Cash Collateralized or otherwise secured. If the Administrative Agent is removed, the procedures set forth in this Section 10.9 shall apply in appointing a successor Administrative Agent.

-69-

10.10 Issuing Lender. The provisions of this Section 10 applicable to the Administrative Agent shall apply to the Issuing Lender in the performance of its duties under the Loan Documents, mutatis mutandis.

10.11 Others. None of the Joint Lead Arrangers, the Joint Book Running Managers, the Syndication Agent, nor the Documentation Agents, in such respective capacities, shall have any duties or responsibilities, or incur any liabilities, under this Agreement or the other Loan Documents.

10.12 Hedging Arrangements. To the extent any Affiliate of a Lender is a party to a Hedging Agreement with the Borrowers and thereby becomes a beneficiary of the Liens described in Section 4.16 hereof pursuant to the Security Documents, such Affiliate of a Lender shall be deemed to appoint the Administrative Agent its nominee and agent, to act for and on behalf of such Affiliate in connection with the Security Documents and to be bound by the terms of this Section 10.

SECTION 11

MISCELLANEOUS

11.1 Amendments and Waivers. Neither this Agreement nor any other Loan Document, nor any terms hereof or thereof may be amended, supplemented or modified except in accordance with the provisions of this Section 11.1. The Required Lenders may, or, with the written consent of the Required Lenders, the Administrative Agent may, from time to time, (a) enter into with the applicable Borrower written amendments, supplements or modifications hereto and to the other Loan Documents for the purpose of adding any provisions to this Agreement or the other Loan Documents or changing in any manner the rights of the Lenders or of the applicable Borrower hereunder or thereunder or (b) waive, on such terms and conditions as the Required Lenders or the Administrative Agent, as the case may be, may specify in such instrument, any of the requirements of this Agreement or the other Loan Documents or any Default or Event of Default and its consequences; provided, however, that no such waiver and no such amendment, supplement or modification shall (i) reduce the principal amount, or extend the scheduled date of final maturity, of any Loan, or reduce the stated rate of any interest or fee payable hereunder or extend the scheduled date of any payment thereof or increase the principal amount or extend the expiration date of any Lender’s Commitments, or change the limits on Letter of Credit Outstandings as set forth in Section 3.1(a), in each case without the consent of each Lender affected thereby, (ii) amend, modify or waive the definition of Technical Lenders, any provision of Section 4.9, 4.10, 4.16 or 9.2 without the written consent of each Lender, (iii) amend, modify or waive any provision of this Section 11.1 or reduce the percentage specified in the definition of Required Lenders or Super Majority Lenders (or modify any provision of this Agreement or any other Loan Document to provide that an action currently requiring the approval of or consent by the Required Lenders or Super Majority Lenders, as applicable, may be taken with the consent or approval by a lower percentage of Lenders), or consent to the assignment or transfer by either Borrower of any of its rights and obligations under this Agreement and the other Loan Documents other than in accordance with the terms of the applicable Loan Documents, in each case without the written consent of all the Lenders, (iv) release, or subordinate the interest of the Administrative Agent in, any substantial portion of the collateral for the Obligations hereunder (except as specifically provided herein) without the written consent of each Lender, (v) change Section 4.8(a) or Section 11.8(a) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, or (vi) amend, modify or waive any provision of Section 10 without the written consent of the then Administrative Agent and Issuing Lender. Any such waiver and any such amendment, supplement or modification shall apply equally to each of the Lenders and shall be binding upon the Borrowers, the Lenders, the Administrative Agent and all future holders of the Loans. In the case of any waiver, the Borrowers, the Lenders and the Administrative Agent shall be restored to their former positions and rights hereunder and under the other Loan Documents, and any Default or Event of Default waived shall be deemed to be cured and not continuing; no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon. Notwithstanding anything to the contrary herein, no Defaulting Lender shall have any right to approve or disapprove any amendment, waiver or consent hereunder (and any amendment, waiver or consent which by its terms requires the consent of all Lenders or each affected Lender may be effected with the consent of the Lenders other than Defaulting Lender), except that (x) the Commitments of any Defaulting Lender may not be increased or extended, nor the principal amount of any Loan owed to such Defaulting Lender reduced or the final maturity thereof extended, without the consent of such Lender, (y) any waiver, amendment or modification requiring the consent of all Lenders or each affected Lender that by its terms affects any Defaulting Lender more adversely than other affected Lenders shall require the consent of such Defaulting Lender, and (z) any waiver, amendment or modification changing the voting rights of a Defaulting Lender shall require the consent of each Lender, including the Defaulting Lender. Notwithstanding anything to the contrary contained herein, solely for purposes of this Section 11.1, the term “Loan Documents” shall not include the Fee Letters.

-73-

11.6 Successors and Assigns; Participations and Assignments. (a) This Agreement shall be binding upon and inure to the benefit of the Borrowers, the Lenders, the Administrative Agent, all future holders of the Loans and any Notes hereunder and their respective successors and assigns, except that the Borrowers may not assign or transfer any of its rights or obligations under this Agreement without the prior written consent of each Lender.

(b) Any Lender may, in the ordinary course of its commercial banking or lending business and in accordance with applicable law and at no cost or expense to the Borrowers, at any time sell to one or more banks or other entities (other than a Defaulting Lender or a subsidiary thereof) (“Participants”) participating interests in any Loan owing to such Lender, any Commitment of such Lender or any other interest of such Lender hereunder and under the other Loan Documents. In the event of any such sale by a Lender of a participating interest to a Participant, (i) such Lender’s obligations under this Agreement to the other parties to this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible for the performance thereof, (iii) such Lender shall remain the holder of any such Loan (and any Note evidencing such Loan) for all purposes under this Agreement and the other Loan Documents, (iv) the Borrowers and the Administrative Agent shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement and the other Loan Documents, and (v) in any proceeding under the Bankruptcy Code the Lender shall be, to the extent permitted by law, the sole representative with respect to the obligations held in the name of such Lender, whether for its own account or for the account of any Participant. No Lender shall be entitled to create in favor of any Participant, in the participation agreement pursuant to which such Participant’s participating interest shall be created or otherwise, any right to vote on, consent to or approve any matter relating to this Agreement or any other Loan Document except for those specified in clauses (i), (ii) and (v) of the proviso to Section 11.1. The Borrowers agree that each Participant shall be entitled to the benefits of Sections 4.13 and 4.14 with respect to its participation in the Commitments and the Loans and Letters of Credit outstanding from time to time as if it was a Lender; provided that, in the case of Section 4.13, such Participant shall have complied with the requirements of said Section and provided, further, that no Participant shall be entitled to receive any greater amount pursuant to any such Section than the transferor Lender would have been entitled to receive in respect of the amount of the participation transferred by such transferor Lender to such Participant had no such transfer occurred.

-74-

(c) Any Lender may, in the ordinary course of its commercial banking or lending business and in accordance with applicable law, at any time and from time to time assign to any Lender or any Affiliate thereof or, with the prior written consent of the Administrative Agent, each Issuing Lender and the Borrowers (which in each case shall not be unreasonably withheld), to an additional bank or financial institution or other entity (other than a Defaulting Lender or any of its subsidiaries or any Person who, upon becoming a Lender hereunder, would constitute any of the foregoing Persons) (an “Assignee”) all or any part of its rights and obligations under this Agreement and the other Loan Documents including, without limitation, its Commitments, L/C Commitments, Loans and L/C Participating Interests, pursuant to an Assignment and Acceptance, substantially in the form of Exhibit C, executed by such Assignee, such assigning Lender (and, in the case of an Assignee that is not then a Lender, by the Borrowers, the Administrative Agent and each Issuing Lender) and delivered to the Administrative Agent for its acceptance and recording in the Register, provided that (i) (unless EPEP and the Administrative Agent otherwise consent in writing) no such transfer to an Assignee (other, than a Lender or any Affiliate thereof) shall be in an aggregate principal amount less than $1,000,000 in the aggregate (or, if less, the full amount of such assigning Lender’s Loans, L/C Participating Interests and Commitments), and (ii) if any Lender assigns all or any part of its rights and obligations under this Agreement to one of its Affiliates in connection with or in contemplation of the sale or other disposition of its interest in such Affiliate, the Borrowers’ prior written consent shall be required for such assignment (which shall not be unreasonably withheld). Upon such execution, delivery, acceptance and recording, from and after the effective date determined pursuant to such Assignment and Acceptance, (x) the Assignee thereunder shall be a party hereto and, to the extent provided in such Assignment and Acceptance, have the rights and obligations of a Lender hereunder with a Commitment and L/C Commitment as set forth therein, and (y) the assigning Lender thereunder shall, to the extent provided in such Assignment and Acceptance, be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all or the remaining portion of an assigning Lender’s rights and obligations under this Agreement, such assigning Lender shall cease to be a party hereto). Notwithstanding any provision of this paragraph (c) and paragraph (e) of this Section 11.6, the consent of the Borrowers shall not be required, and, unless requested by the Assignee and/or the assigning Lender, new Notes shall not be required to be executed and delivered by the Borrowers, for any assignment which occurs at any time when any of the events described in Section 9.1 shall have occurred and be continuing.

(d) The Administrative Agent, on behalf of the Borrowers, shall maintain at the address of the Administrative Agent referred to in Section 11.2 a copy of each Assignment and Acceptance delivered to it and a register (the “Register”) for the recordation of the names and addresses of the Lenders and the Commitments of, and principal amounts of the Loans owing to, each Lender from time to time. In addition, the Administrative Agent shall maintain on the Register information regarding the designation, and revocation of designation, of any Lender as a Defaulting Lender. The entries in the Register shall be conclusive, in the absence of manifest error, and the Borrowers, the Administrative Agent and the Lenders may (and, in the case of any Loan or other obligation hereunder not evidenced by a Note, shall) treat each Person whose name is recorded in the Register as the owner of a Loan or other obligation hereunder as the owner thereof for all purposes of this Agreement and the other Loan Documents, notwithstanding any notice to the contrary. Any assignment of any Loan or other obligation hereunder not evidenced by a Note shall be effective only upon appropriate entries with respect thereto being made in the Register. The Register shall be available for inspection by the Borrowers or any Lender at any reasonable time and from time to time upon reasonable prior notice.

-75-

(e) Notwithstanding anything in this Agreement to the contrary, no assignment under Section 11.6(c) of any rights or obligations under or in respect of the Loans, the Notes or the Letters of Credit shall be effective unless and until the Administrative Agent shall have recorded the assignment pursuant to Section 11.6(d). Upon its receipt of an Assignment and Acceptance executed by an assigning Lender and an Assignee (and, in the case of an Assignee that is not then a Lender or an affiliate thereof, by the Borrowers and the Administrative Agent) together with payment to the Administrative Agent of a registration and processing fee of $3,500 (other than in the case of an assignment by a Lender to an affiliate of such Lender), the Administrative Agent shall (i) promptly accept such Assignment and Acceptance and (ii) on the effective date determined pursuant thereto record the information contained therein in the Register and give notice of such acceptance and recordation to the Lenders and the Borrowers. On or prior to such effective date, the assigning Lender shall surrender any outstanding Notes held by it all or a portion of which are being assigned, and the Borrowers, at their own expense, shall, upon the request to the Administrative Agent by the assigning Lender or the Assignee, as applicable, execute and deliver to the Administrative Agent (in exchange for the outstanding Notes of the assigning Lender) a new Note to the order of such Assignee in an amount equal to the lesser of (A) the amount of such Assignee’s Commitment and (B) the aggregate principal amount of all Loans made by such Assignee, after giving effect to such Assignment and Acceptance and, if the assigning Lender has retained a Commitment hereunder, a new Note to the order of the assigning Lender in an amount equal to the lesser of (A) the amount of such Lender’s Commitment and (B) the aggregate principal amount of all Loans made by such Lender, after giving effect to such Assignment and Acceptance. Any such new Notes shall be dated the Effective Date and shall otherwise be in the form of the Note replaced thereby. Any Notes surrendered by the assigning Lender shall be returned by the Administrative Agent to the Borrowers marked “canceled.”

(f) The Borrowers authorize each Lender to disclose to any Participant or Assignee (each, a “Transferee”) and any prospective Transferee, any and all financial information in such Lender’s possession concerning the Borrowers and their Affiliates which has been delivered to such Lender by or on behalf of the Borrowers pursuant to this Agreement or which has been delivered to such Lender by or on behalf of the Borrowers in connection with such Lender’s credit evaluation of the Borrowers and their Affiliates prior to becoming a party to this Agreement.

(g) For avoidance of doubt, the parties to this Agreement acknowledge that the provisions of this Section concerning assignments of Loans and Notes relate only to absolute assignments and that such provisions do not prohibit assignments creating security interests, including, without limitation, any pledge or assignment by a Lender of any Loan or Note to any Federal Reserve Bank or central bank with jurisdiction over such Lender in accordance with applicable law.

(h) Notwithstanding any provision of this Section, a Lender may not (i) assign an interest in the Loans or its Note to (x) any Defaulting Lender or any of its subsidiaries, or any Person who, upon becoming a Lender hereunder, would constitute any of the foregoing Persons or (y) a Borrower or an Affiliate of a Borrower or (ii) grant a participation in the Loans or its Note to a Defaulting Lender, a subsidiary thereof, a Borrower or an Affiliate of a Borrower.

-76-

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

(j) 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 any party hereunder arising from that Lender’s having been a Defaulting Lender.

11.7 Confidentiality. Each of the Administrative Agent, each Issuing Lender and each Lender agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ directors, officers, employees and agents, including accountants, legal counsel and other advisors involved in the financing provided for herein (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by any regulatory authority, (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, applicable to it, (d) to any other party to this Agreement, (e) in connection with the exercise of any remedies hereunder or any suit, action or proceeding relating to this Agreement or the enforcement of rights hereunder, (f) subject to an agreement to comply with the provisions of this Sections 11.7 or a separate agreement containing provisions at least as restrictive as those of this Section, to (i) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement, (ii) any pledgee referred to in Section 11.6(g), or (iii) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to any Borrower and its obligations, (g) with the consent of a Borrower or (h) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section or (ii) becomes available to the Administrative Agent, any Issuing Lender or any Lender on a nonconfidential basis from a source other than a Borrower or any of its Subsidiaries, the Administrative Agent, any Issuing Lender or any other Lender. For the purposes of this Section, “Information” means all information received from a Borrower or any of its Subsidiaries relating to any Borrower or any of its Subsidiaries or its businesses, other than any such information that is available to the Administrative Agent, any Issuing Lender or any Lender on a nonconfidential basis prior to disclosure by such Borrower; provided that, in the case of information received from a Borrower after the date hereof, such information is clearly identified at the time of delivery as confidential. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person would accord to its own confidential information; and nothing in the foregoing authorization shall apply to any disclosure that would constitute a violation of applicable federal and state securities laws.

-77-

11.8 Adjustments; Set-off. (a) If any Lender (a “Benefitted Lender”) shall at any time receive any payment of all or part of its Loans or Reimbursement Obligations, or interest thereon, or receive any collateral in respect thereof (whether voluntarily or involuntarily, by set-off, pursuant to events or proceedings of the nature referred to in Section 9.1(f), or otherwise), in a greater proportion than any such payment to or collateral received by any other Lender, if any, in respect of such other Lender’s Loans or Reimbursement Obligations, or interest thereon, other than payments expressly permitted by this Agreement, the Loan Documents, or in connection with any assignments or participations permitted by this Agreement, such Benefitted Lender shall purchase for cash from the other Lenders a participating interest in such portion of each such other Lender’s Loans or Reimbursement Obligations, or shall provide such other Lenders with the benefits of any such collateral, or the proceeds thereof, as shall be necessary to cause such Benefitted Lender to share the excess payment or benefits of such collateral or proceeds ratably with each of the Lenders; provided, however, that if all or any portion of such excess payment or benefits is thereafter recovered from such Benefitted Lender, such purchase shall be rescinded, and the purchase price and benefits returned, to the extent of such recovery, but without interest.

(b) In addition to any rights and remedies of the Lenders provided by law, each Lender shall have the right, without prior notice to the Borrowers, any such notice being expressly waived by the Borrowers to the extent permitted by applicable law, upon any amount becoming due and payable by the Borrowers hereunder (whether at the stated maturity, by acceleration or otherwise) to set-off and appropriate and apply against such amount any and all deposits (general or special, time or demand, provisional or final), in any currency, and any other credits, indebtedness or claims, in any currency, in each case whether direct or indirect, absolute or contingent, matured or unmatured, at any time held or owing by such Lender or any branch or agency thereof to or for the credit or the account of the Borrowers, as the case may be. Each Lender agrees promptly to notify the Borrowers and the Administrative Agent after any such set-off and application made by such Lender, provided that, to the extent permitted by applicable law, the failure to give such notice shall not affect the validity of such set-off and application. In the event that any Defaulting Lender shall exercise any such right of set-off, (a) all amounts so set off shall be paid over immediately to the Administrative Agent for further application in accordance with the provisions of Section 2.5 and, pending such payment, shall be segregated by such Defaulting Lender from its other funds and deemed held in trust for the benefit of the Administrative Agent, the Issuing Lenders and the Lenders, and (b) the Defaulting Lender shall provide promptly to the Administrative Agent a statement describing in reasonable detail the Obligations owing to such Defaulting Lender as to which it exercised such right of setoff.

11.9 Counterparts. This Agreement may be executed by one or more of the parties to this Agreement on any number of separate counterparts (including by facsimile or other electronic transmission), and all of said counterparts taken together shall be deemed to constitute one and the same instrument. A set of the copies of this Agreement signed by all the parties shall be lodged with the Borrowers and the Administrative Agent.

-78-

11.10 Severability. Any provision of this Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. Without limiting the foregoing provisions of this Section 11.10, if and to the extent that the enforceability of any provisions in this Agreement relating to Defaulting Lenders shall be limited by applicable law, as determined in good faith by the Administrative Agent or any Issuing Lender, as applicable, then such provisions shall be deemed to be in effect only to the extent not so limited.

11.11 Integration. This Agreement and the other Loan Documents represent the agreement of the Borrowers, the Administrative Agent and the Lenders with respect to the subject matter hereof, and there are no promises, undertakings, representations or warranties by the Administrative Agent or any Lender relative to subject matter hereof not expressly set forth or referred to herein or in the other Loan Documents. THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT AMONG THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR ORAL AGREEMENTS AMONG THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG THE PARTIES.

11.12 GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

11.13 Submission To Jurisdiction; Waivers. Each party hereto hereby irrevocably and unconditionally:

(a) submits for itself and its property in any legal action or proceeding relating to this Agreement and the other Loan Documents to which it is a party, or for recognition and enforcement of any judgment in respect thereof, to the non-exclusive general jurisdiction of the Supreme Court of the State of New York sitting in New York County and of the United States District Court of the Southern District of New York, and appellate courts from any thereof;

(b) consents that any such action or proceeding may be brought in such courts and waives any objection that it may now or hereafter have to the venue of any such action or proceeding in any such court or that such action or proceeding was brought in an inconvenient court and agrees not to plead or claim the same;

(c) agrees that service of process in any such action or proceeding may be effected by mailing a copy thereof by registered or certified mail (or any substantially similar form of mail), postage prepaid, to it at its address set forth in Section 11.2 or at such other address of which the Administrative Agent shall have been notified pursuant thereto;

-79-

(d) agrees that nothing herein shall affect the right to effect service of process in any other manner permitted by law or shall limit the right to sue in any other jurisdiction; and

(e) waives, to the maximum extent not prohibited by law, but without limiting or otherwise impairing any Borrower’s obligations under Section 11.5, any right it may have to claim or recover in any legal action or proceeding arising out of, in connection with, or as a result of, this Agreement, any other Loan Document or any agreement or instrument contemplated hereby, the transactions contemplated hereby or thereby, any Loan or Letter of Credit or the use of the proceeds thereof, any special, exemplary, punitive or consequential damages.

11.14 Acknowledgments. The Borrowers hereby acknowledge that:

(a) they have been advised by counsel in the negotiation, execution and delivery of this Agreement and the other Loan Documents;

(b) neither the Administrative Agent nor any Lender has any fiduciary relationship with or duty to the Borrowers arising out of or in connection with this Agreement or any of the other Loan Documents, and the relationship between Administrative Agent and Lenders, on one hand, and the Borrower, on the other hand, in connection herewith or therewith is solely that of debtor and creditor; and

(c) no joint venture is created hereby or by the other Loan Documents or otherwise exists by virtue of the transactions contemplated hereby among the Lenders or among the Borrowers and the Lenders.

11.15 WAIVERS OF JURY TRIAL. THE BORROWERS, THE ADMINISTRATIVE AGENT AND THE LENDERS HEREBY KNOWINGLY AND INTENTIONALLY, IRREVOCABLY AND UNCONDITIONALLY WAIVE TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AND FOR ANY COUNTERCLAIM THEREIN.

11.16 Release of Borrowing Base Properties; Consent to Release of Producer’s Lien. The Administrative Agent is hereby authorized by the Lenders, and hereby agrees, (a) to execute, at the cost and expense of the Borrowers and pursuant to documentation reasonably acceptable to the Administrative Agent, partial releases of the Borrowing Base Properties to the extent such Borrowing Base Properties are substituted in accordance with Section 4.16(e) or sold in accordance with the terms of the Mortgage and Section 8.6 and (b) to consent, at the cost and expense of the Borrowers and pursuant to documentation reasonably acceptable to the Administrative Agent, to the release of any producer’s Lien securing any obligations owed to a Borrower.

11.17 Limitation on Interest. The Borrowers, the Administrative Agent and the Lenders intend to contract in strict compliance with applicable usury law from time to time in effect. In furtherance thereof such persons stipulate and agree that none of the terms and provisions contained in the Loan Documents shall ever be construed to provide for interest in excess of the maximum amount of interest permitted to be charged by applicable law from time to time in effect. Neither either Borrower nor any present or future guarantors, endorsers, or other Persons hereafter becoming liable for payment of any Obligation shall ever be liable for unearned interest thereon or shall ever be required to pay interest thereon in excess of the maximum amount that may be lawfully charged under applicable law from time to time in effect, and the provisions of this section shall control over all other provisions of the Loan Documents which may be in conflict or apparent conflict herewith. The Administrative Agent and the Lenders expressly disavow any intention to charge or collect excessive unearned interest or finance charges in the event the maturity of any Obligation is accelerated. If (a) the maturity of any Obligation is accelerated for any reason, (b) any Obligation is prepaid and as a result any amounts held to constitute interest are determined to be in excess of the legal maximum, or (c) any Lender or may other holder of any or all of the Obligations shall otherwise collect moneys which are determined to constitute interest which would otherwise increase the interest on any or all of the Obligations to an amount in excess of that permitted to be charged by applicable law then in effect, then all sums determined to constitute interest in excess of such legal limit shall, without penalty, be promptly applied to reduce the then outstanding principal of the related Obligations or, at such Lender’s or holder’s option, promptly returned to Borrower or the other payor thereof upon such determination. In determining whether or not the interest paid or payable, under any specific circumstance, exceeds the maximum amount permitted under applicable law, Lenders, the Administrative Agent and the Borrowers (and any other payers thereof) shall to the greatest extent permitted under applicable law, (i) characterize any non-principal payment as an expense, fee or premium rather than as interest, (ii) exclude voluntary prepayments and the effects thereof, and (iii) amortize, prorate, allocate, and spread the total amount of interest throughout the entire contemplated term of the instruments evidencing the Obligations in accordance with the amounts outstanding from time to time thereunder and the maximum legal rate of interest from time to time in effect under applicable law in order to lawfully charge the maximum amount of interest permitted under applicable law. To the extent that the interest rate laws of the State of Texas are applicable to this Agreement, any Note or any other Loan Document, the applicable interest rate ceiling is the indicated (weekly) ceiling determined in accordance with Chapter 303 of the Texas Finance Code, as amended, and, to the extent that any Obligation under this Agreement, any Note or any other Loan Document is deemed an open end account as such term is defined in Chapter 302 of the Texas Finance Code, as amended, Administrative Agent retains the right to modify the interest rate in accordance with applicable law.

11.18 Joint and Several Obligations of Borrowers.

(a) The Borrowers state and acknowledge that: (i) pursuant to this Agreement, the Borrowers desire to utilize their borrowing potential on a consolidated basis to the same extent possible if they were merged into a single entity and that this Agreement reflects the establishment of credit facilities which would not otherwise be available to such entity if each Borrower were not jointly and severally liable for payment of the Indebtedness; (ii) each Borrower has determined that it will benefit specifically and materially from the advances of credit contemplated by this Agreement; (iii) it is both a condition precedent to the obligations of the Lenders hereunder and a desire of the Borrowers that each Borrower execute and deliver this Agreement; and (iv) each Borrower has requested and bargained for the structure and terms of and security for the advances contemplated by this Agreement.

(b) Each Borrower hereby irrevocably and unconditionally: (i) agrees that it is jointly and severally liable to Lenders for the full and prompt payment of the Indebtedness and the performance by each Borrower of its obligations hereunder in accordance with the terms hereof; (ii) agrees to fully and promptly perform all of its Obligations hereunder with respect to each advance of credit hereunder as if such advance had been made directly to it; and (iii) agrees as a primary obligation to indemnify Lenders on demand for and against any loss incurred by a Lender as result of any of the obligations of any one or more of the Borrowers being or becoming void, voidable, unenforceable or ineffective for any reason whatsoever, whether or not known to a Lender or any Person, the amount of such loss being the amount which each Lender would otherwise have been entitled to recover from any one or more of the Borrowers whose obligation becomes void, voidable, unenforceable or ineffective.

-81-

It is the intent of each Borrower that the Indebtedness, obligations and liability hereunder of no one of them be subject to challenge on any basis, including, without limitation, pursuant to any applicable fraudulent conveyance or fraudulent transfer laws. Accordingly, as of the date hereof, the liability of each Borrower under this Section 11.18, together with all of its other liabilities to all Persons as of the date hereof and as of any other date on which a transfer or conveyance is deemed to occur by virtue of this Agreement, calculated in amount sufficient to pay its probable net liabilities on its existing Indebtedness as the same become absolute and matured (“Dated Liabilities”) is, and is to be, less than the amount of the aggregate of a fair valuation of its property as of such corresponding date (“Dated Assets”). To this end, each Borrower under this Section 11.18, (a) grants to and recognizes in each other Borrower, ratably, rights of subrogation and contribution in the amount, if any, by which the Dated Assets of such Borrower, but for the aggregate of subrogation and contribution in its favor recognized herein, would exceed the Dated Liabilities of such Borrower or, as the case may be, and (b) acknowledges receipt of and recognizes its right to subrogation and contribution ratably from each of the other Borrowers in the amount, if any, by which the Dated Liabilities of such Borrower, but for the aggregate of subrogation and contribution in its favor recognized herein, would exceed the Dated Assets of such Borrower under this Section 11.18. In recognizing the value of the Dated Assets and the Dated Liabilities, it is understood that Borrowers will recognize, to at least the same extent of their aggregate recognition of liabilities hereunder, their rights to subrogation and contribution hereunder. It is a material objective of this Section 11.18 that each Borrower recognizes rights to subrogation and contribution rather than be deemed to be insolvent (or in contemplation thereof) by reason of an arbitrary interpretation of its joint and several obligations hereunder. In addition to and not in limitation of the foregoing provisions of this Section 11.18, the Borrowers and Lenders hereby agree and acknowledge that it is the intent of each Borrower and of each Lender that the obligations of each Borrower hereunder be in all respects in compliance with, and not be voidable pursuant to, applicable fraudulent conveyance and fraudulent transfer laws.

11.19 Amendment and Restatement. The Borrowers, the Administrative Agent and the Lenders agree that this Agreement is an amendment and restatement of the Existing Credit Agreement in its entirety, and the terms and provisions hereof supersede the terms and provisions thereof. The parties further agree that this Agreement is not a new or substitute credit agreement or a novation of the Existing Credit Agreement, and that (a) the Indebtedness of the Borrowers under the Existing Credit Agreement shall be deemed to be Indebtedness of the Borrowers outstanding under and governed by this Agreement, and (b) all Liens securing the Obligations of the Borrowers under the Existing Credit Agreement and Loan Documents shall continue in full force and effect to secure the Obligations under this Agreement and the Loan Documents.

-82-

11.20 USA Patriot Act Notice. Each Lender and the Administrative Agent (for itself and not on behalf of any Lender) hereby notifies the Borrowers that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”), it is required to obtain, verify and record information that identifies the Borrowers, which information includes the name and address of the Borrowers and other information that will allow such Lender or the Administrative Agent, as applicable, to identify the Borrowers in accordance with the Act.
