Each Borrowing Request shall constitute a representation that the amount of the requested Borrowing shall not cause the total Credit Exposures to exceed the total Commitments (i.e., the lesser of the Aggregate Maximum Credit Amounts and the then effective Borrowing Base).

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

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

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

Section 2.05 Funding of Borrowings.

(a) Funding by Lenders. Each Lender shall make each Loan to be made by it hereunder on the proposed date thereof by wire transfer of immediately available funds by 1:00 p.m., New York, New York time, to the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders. The Administrative Agent will make such Loans available to the Borrower by promptly crediting the amounts so received, in like funds, to an account designated by the Borrower in the applicable Borrowing Request.

(b) Presumption of Funding by the Lenders. Unless the Administrative Agent shall have received notice from a Lender prior to the proposed date of any Borrowing (or, in the case of any ABR Borrowing, prior to 12:00 p.m., New York, New York time, on the date of such Borrowing) that such Lender will not make available to the Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in accordance with Section 2.05(a) and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing available to the Administrative Agent, then the applicable Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (i) in the case of such Lender, the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation or (ii) in the case of the Borrower, the interest rate applicable to ABR Loans. If such Lender pays such amount to the Administrative Agent, then such amount shall constitute such Lender’s Loan included in such Borrowing.

Upon any Redetermination of the Borrowing Base pursuant to Section 2.07(b), Section 2.07(c) or Section 2.07(d), the recalculated or redetermined Borrowing Base shall become effective and applicable to the Borrower, the Administrative Agent, the Issuing Bank and the Lenders automatically on the applicable Redetermination Date without any necessary action of the Borrower, the Administrative Agent, the Lenders, or any other Person, and shall be effective until the next Redetermination of the Borrowing Base pursuant to this Agreement. The Administrative Agent shall promptly deliver notice of any such recalculated or redetermined Borrowing Base to the Borrower and the Lenders; provided that any failure by the Administrative Agent to deliver such notice shall not negate the effectiveness of such recalculated or redetermined Borrowing Base.

Section 2.08 Letters of Credit.

(a) General. Subject to the terms and conditions set forth herein, the Borrower may request the Issuing Bank to issue US dollar denominated Letters of Credit for its own account or for the account of any other Loan Party, in a form reasonably acceptable to the Administrative Agent and the Issuing Bank, at any time and from time to time during the period from the Effective Date until the day which is five (5) Business Days prior to the end of the Availability Period. In the event of any inconsistency between the terms and conditions of this Agreement and the terms and conditions of any form of letter of credit application or other agreement submitted by the Borrower to, or entered into by the Borrower with, the Issuing Bank relating to any Letter of Credit, the terms and conditions of this Agreement shall control.

(b) Notice of Issuance, Amendment, Renewal, Extension; Certain Conditions. To request the issuance of a Letter of Credit (or the amendment, renewal or extension of an outstanding Letter of Credit), the Borrower shall hand deliver or telecopy (or transmit by

- 31 -

electronic communication, if arrangements for doing so have been approved by the Issuing Bank) to the Issuing Bank and the Administrative Agent (unless otherwise agreed by the Issuing Bank, not less than three (3) Business Days in advance of the requested date of issuance, amendment, renewal or extension) a notice:

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

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

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

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

(v) specifying the name and address of the beneficiary thereof and such other information as shall be necessary to prepare, amend, renew or extend such Letter of Credit; and

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

Each notice shall constitute a representation that after giving effect to the requested issuance, amendment, renewal or extension, as applicable, (x) the LC Exposure shall not exceed the LC Commitment and (y) the total Credit Exposures shall not exceed the total Commitments (i.e., the lesser of the Aggregate Maximum Credit Amounts and the then effective Borrowing Base).

If requested by the Issuing Bank, the Borrower also shall submit a letter of credit application on the Issuing Bank’s standard form in connection with any request for a Letter of Credit and shall guarantee the reimbursement of any Letter of Credit issued for the account of a Loan Party.

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

(d) Participations. By the issuance of a Letter of Credit (or an amendment to an existing Letter of Credit increasing the amount thereof) and without any further action on the part of the Issuing Bank or the Lenders, the Issuing Bank hereby grants to each Lender, and each Lender hereby acquires from the Issuing Bank, a participation in such Letter of Credit equal to such Lender’s Applicable Percentage of the aggregate amount available to be drawn under such Letter of Credit. In consideration and in furtherance of the foregoing, each Lender hereby absolutely and unconditionally agrees to pay to the Administrative Agent, for the account of the

- 32 -

Issuing Bank, such Lender’s Applicable Percentage of each LC Disbursement made by the Issuing Bank and not reimbursed by the Borrower on the date due as provided in Section 2.08(e), or of any reimbursement payment required to be refunded to the Borrower for any reason. Each Lender acknowledges and agrees that its obligation to acquire participations pursuant to this Section 2.08(d) in respect of Letters of Credit is absolute and unconditional and shall not be affected by any circumstance whatsoever, including any amendment, renewal or extension of any Letter of Credit or the occurrence and continuance of a Default or reduction or termination of the Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever.

(e) Reimbursement. If the Issuing Bank shall make any LC Disbursement, the Borrower shall reimburse such LC Disbursement by paying to the Administrative Agent an amount equal to such LC Disbursement not later than the fifth (5th) Business Day after the Borrower shall have received notice of such LC Disbursement, together with interest on the amount disbursed from and including the date of disbursement until payment in full of such disbursed amount at a varying rate per annum equal to (i) the then applicable interest rate for ABR Loans for each day such LC Disbursement shall remain outstanding through the fifth (5th) Business Day following its receipt of notice of such disbursement and (ii) thereafter, the post default rate for ABR Loans for the period from and including the sixth Business Day following the date of such disbursement to and including the date of repayment in full of such disbursed amount; provided that, unless the Borrower shall have notified the Administrative Agent to the contrary not later than 10:00 a.m., New York City time, on the Business Day next following the date on which the Borrower shall have been notified of such LC Disbursement, the Borrower will be deemed to have requested, and the Borrower does hereby request under such circumstances, in accordance with Section 2.03 that such payment be financed with an ABR Borrowing on such Business Day in an equivalent amount and, to the extent the Borrower satisfies the condition precedent to such ABR Borrowing set forth in Section 6.02(b), the Borrower’s obligation to make such payment shall be discharged with the proceeds of the requested ABR Borrowing. If the Borrower fails to make such payment when due and the Borrower is not entitled to make a Borrowing in the amount of such payment, the Administrative Agent shall notify each Lender of the applicable LC Disbursement, the payment then due from the Borrower in respect thereof and such Lender’s Applicable Percentage thereof. Promptly following receipt of such notice, each Lender shall pay to the Administrative Agent its Applicable Percentage of the payment then due from the Borrower, in the same manner as provided in Section 2.05 with respect to Loans made by such Lender (and Section 2.05 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Administrative Agent shall promptly pay to the Issuing Bank the amounts so received by it from the Lenders. Promptly following receipt by the Administrative Agent of any payment from the Borrower pursuant to this Section 2.08(e), the Administrative Agent shall distribute such payment to the Issuing Bank or, to the extent that Lenders have made payments pursuant to this Section 2.08(e) to reimburse the Issuing Bank, then to such Lenders and the Issuing Bank as their interests may appear. Any payment made by a Lender pursuant to this Section 2.08(e) to reimburse the Issuing Bank for any LC Disbursement shall not constitute a Loan and shall not relieve the Borrower of its obligation to reimburse such LC Disbursement.

(f) Obligations Absolute. The Borrower’s obligation to reimburse LC Disbursements as provided in Section 2.08(e) shall be absolute, unconditional and irrevocable,

- 33 -

and shall be performed strictly in accordance with the terms of this Agreement under any and all circumstances whatsoever and irrespective of (i) any lack of validity or enforceability of any Letter of Credit, any Letter of Credit Agreement or this Agreement, or any term or provision therein, (ii) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect, (iii) payment by the Issuing Bank under a Letter of Credit against presentation of a draft or other document that does not comply with the terms of such Letter of Credit or any Letter of Credit Agreement, or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section 2.08(f), constitute a legal or equitable discharge of, or provide a right of setoff against, the Borrower’s obligations hereunder. Neither the Administrative Agent, the Lenders nor the Issuing Bank, nor any of their Related Parties shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of the Issuing Bank; provided that the foregoing shall not be construed to excuse the Issuing Bank from liability to the Borrower to the extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by the Borrower to the extent permitted by applicable law) suffered by the Borrower that are caused by the Issuing Bank’s failure to exercise care when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof. The parties hereto expressly agree that, in the absence of gross negligence or willful misconduct on the part of the Issuing Bank, the Issuing Bank shall be deemed to have exercised all requisite care in each such determination. In furtherance of the foregoing and without limiting the generality thereof, the parties agree that, with respect to documents presented which appear on their face to be in substantial compliance with the terms of a Letter of Credit, the Issuing Bank may, in good faith, either accept and make payment upon such documents without responsibility for further investigation or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit.

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

(h) Interim Interest. If the Issuing Bank shall make any LC Disbursement, then, until the Borrower shall have reimbursed the Issuing Bank for such LC Disbursement, the unpaid amount thereof shall bear interest, for each day from and including the date such LC Disbursement is made to but excluding the date that the Borrower reimburses such LC Disbursement, at the rate per annum then applicable to ABR Loans. Interest accrued pursuant to this Section 2.08(h) shall be for the account of the Issuing Bank, except that interest accrued on and after the date of payment by any Lender pursuant to Section 2.08(e) to reimburse the Issuing Bank shall be for the account of such Lender to the extent of such payment.

- 34 -

(i) Cash Collateralization. If (i) any Event of Default shall occur and be continuing and the Borrower receives notice from the Administrative Agent or the Majority Lenders demanding the deposit of cash collateral pursuant to this Section 2.08(i), or (ii) the Borrower is required to pay to the Administrative Agent the excess attributable to an LC Exposure in connection with any prepayment pursuant to Section 3.04(c), then the Borrower shall deposit not later than one Business Day after receipt of notice from the Administrative Agent (or, if such notice is received after 12:00 p.m. Noon, New York, New York time, not later than the second Business Day after receipt of such notice), in a deposit account with the Administrative Agent, cash collateral for the benefit of the Lenders in an amount equal to, in the case of an Event of Default, the LC Exposure, and in the case of a payment required by Section 3.04(c), the amount of such excess as provided in Section 3.04(c), as of such date plus any accrued and unpaid interest thereon; provided that such deposit shall become immediately due and payable, without demand or notice of any kind, upon the occurrence of any Event of Default with respect to the Borrower or any Restricted Subsidiary described in Section 10.01(g) or Section 10.01(h). The Borrower hereby grants to the Administrative Agent, for the benefit of the Issuing Bank and the Lenders, a first priority perfected security interest in and Lien on such account and all cash, checks, drafts, certificates and instruments, if any, from time to time deposited or held in such account, all deposits or wire transfers made thereto, any and all investments purchased with funds deposited in such account, all interest, dividends, cash, instruments, financial assets and other Property from time to time received, receivable or otherwise payable in respect of, or in exchange for, any or all of the foregoing, and all proceeds, products, accessions, rents, profits, income and benefits therefrom, and any substitutions and replacements therefor. The Borrower’s obligation to deposit amounts pursuant to this Section 2.08(i) shall be absolute and unconditional, without regard to whether any beneficiary of any such Letter of Credit has attempted to draw down all or a portion of such amount under the terms of a Letter of Credit, and, to the fullest extent permitted by applicable law, shall not be subject to any defense or be affected by a right of set-off, counterclaim or recoupment which the Borrower or any Restricted Subsidiray may now or hereafter have against any such beneficiary, the Issuing Bank, the Administrative Agent, the Lenders or any other Person for any reason whatsoever. Such deposit shall be held as collateral securing the payment and performance of the Borrower’s and the other Loan Parties’ obligations under this Agreement and the other Loan Documents in a “securities account” (within the meaning of Article 8 of the UCC) over which the Administrative Agent shall have “control” (within the meaning of the UCC). Notwithstanding the foregoing, the Borrower may direct the Administrative Agent and the “securities intermediary” (within the meaning of the UCC) to invest amounts credited to the securities account, at the Borrower’s risk and expense, in Investments described in Section 9.05(c) through (f). Interest or profits, if any, on such investments shall accumulate in such account. Moneys in such account shall be applied by the Administrative Agent to reimburse, on a pro rata basis, the Issuing Bank for LC Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the Borrower for the LC Exposure at such time or, if the maturity of the Loans has been accelerated, be applied to satisfy other obligations of the Borrower and the Loan Parties under this Agreement or the other Loan Documents. If the Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, and the Borrower is not otherwise required to pay

- 35 -

to the Administrative Agent the excess attributable to an LC Exposure in connection with any prepayment pursuant to Section 3.04(c), then such amount (to the extent not applied as aforesaid) shall be returned to the Borrower within three Business Days after all Events of Default have been cured or waived.

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

(i) all or any part of such LC Exposure shall be reallocated among the non-Defaulting Lenders in accordance with their respective Applicable Percentages but only to the extent (x) the sum of all non-Defaulting Lenders’ Credit Exposures does not exceed the total of all non-Defaulting Lenders’ Commitments, (y) no non-Defaulting Lender’s Credit Exposure exceeds such non-Defaulting Lender’s Commitment, and (z) the conditions set forth in Section 6.02 are satisfied at such time;

(ii) if the reallocation described in clause (i) above cannot, or can only partially, be effected, the Borrower shall within one (1) Business Day following notice by the Administrative Agent (or, if such notice is received after 12:00 p.m. Noon, New York, New York time, within two (2) Business Days following receipt of such notice) cash collateralize such Defaulting Lender’s LC Exposure (after giving effect to any partial reallocation pursuant to clause (i) above) in accordance with the procedures set forth in Section 2.08(i) for so long as such LC Exposure is outstanding;

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

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

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

Notwithstanding any provision of this Agreement to the contrary, so long as any Lender is a Defaulting Lender, the Issuing Bank shall not be required to issue, amend or increase any Letter of Credit, unless it is satisfied that the related exposure will be 100% covered by the

- 36 -

Commitments of the non-Defaulting Lenders and/or cash collateral will be provided by the Borrower in accordance with Section 2.08(j), and participating interests in any such newly issued or increased Letter of Credit shall be allocated among non-Defaulting Lenders in a manner consistent with Section 2.08(j)(i) (and any Defaulting Lender shall not participate therein).

ARTICLE III

(c) Post-Default Rate. Notwithstanding the foregoing, if any principal of or interest on any Loan or any fee or other amount payable by the Borrower or any other Loan Party hereunder or under any other Loan Document is not paid when due, whether at stated maturity, upon acceleration or otherwise, such overdue amount shall bear interest, after as well as before judgment, at a rate per annum equal to 2.0% plus the rate applicable to ABR Loans as provided in Section 3.02(a), or if no rate is then applicable to such amount, at a rate per annum equal to 2.0% plus the highest rate then applicable to ABR Loans as provided in Section 3.02(a).

The applicable Alternate Base Rate, Adjusted LIBO Rate or LIBO Rate shall be determined by the Administrative Agent, and such determination shall be conclusive absent manifest error, and be binding upon the parties hereto.

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

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

Section 3.04 Prepayments.

(a) Optional Prepayments. The Borrower shall have the right at any time and from time to time to prepay any Borrowing in whole or in part, subject to prior notice in accordance with Section 3.04(b), but each prepayment must be in an amount that is an integral multiple of $100,000 and not less than $1,000,000.

Each such notice shall be irrevocable and shall specify the prepayment date and the principal amount of each Borrowing or portion thereof to be prepaid. Promptly following receipt of any such notice relating to a Borrowing, the Administrative Agent shall advise the Lenders of the contents thereof. Each partial prepayment of any Borrowing (other than pursuant to Section 3.04(c)) shall be in an amount that would be permitted in the case of an advance of a Borrowing of the same Type as provided in Section 2.02. Each prepayment of a Borrowing shall be applied ratably to the Loans included in the prepaid Borrowing. Prepayments shall be accompanied by accrued interest to the extent required by Section 3.02.

(i) If, after giving effect to any termination or reduction of the Aggregate Maximum Credit Amounts pursuant to Section 2.06(b), a Commitment Deficiency exists, then the Borrower shall (A) prepay the Borrowings on the date of such termination or reduction in an aggregate principal amount sufficient to fully eliminate such Commitment Deficiency, and (B) if any Commitment Deficiency remains after prepaying all of the

- 38 -

Borrowings as a result of an LC Exposure, pay to the Administrative Agent on behalf of the Lenders an amount equal to such Commitment Deficiency to be held as cash collateral as provided in Section 2.08(i).

(ii) Upon any Redetermination of the Borrowing Base pursuant to Section 2.07, if a Commitment Deficiency results therefrom, the Borrower shall (A) prepay Borrowings in an aggregate principal amount, if any, necessary to fully eliminate such Commitment Deficiency, and (B) if any Commitment Deficiency remains after prepaying all Borrowings as a result of an LC Exposure, pay to the Administrative Agent on behalf of the Lenders an amount equal to such remaining Commitment Deficiency to be held as cash collateral as provided in Section 2.08(i). The Borrower shall make such prepayment and/or deposit of cash collateral on or prior to the second Business Day immediately following the date it receives notice from the Administrative Agent of such reduction of the Borrowing Base and resulting Commitment Deficiency.

- 39 -

its own account, a fronting fee, which shall accrue at the rate of 0.125% per annum on the average daily amount of the LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the date of this Agreement to but excluding the later of the date of termination of the Commitments and the date on which there ceases to be any LC Exposure, provided that in no event shall such fee be less than $500 during any year, and (iii) to the Issuing Bank, for its own account, its standard and customary fees with respect to the issuance, amendment, renewal or extension of any Letter of Credit or processing of drawings thereunder. Participation fees and fronting fees accrued through and including the last day of March, June, September and December of each year will be payable on the third Business Day following such last day, commencing on the first such date to occur after the date of this Agreement; provided that all such fees will be payable on the Termination Date and any such fees accruing after the Termination Date will be payable on demand.

ARTICLE IV

Payments; Pro Rata Treatment; Sharing of Set-offs.

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

(a) Payments by the Borrower. The Borrower shall make each payment required to be made by it hereunder (whether of principal, interest, fees, or reimbursement of LC Disbursements or of amounts payable under Section 5.01, Section 5.02, Section 5.03 or otherwise) prior to 12:00 noon, New York, New York time, on the date when due, in immediately available funds, without defense, deduction, recoupment, set-off or counterclaim. Fees, once paid, shall be fully earned and shall not be refundable under any circumstances. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at its offices specified in Section 12.01, except payments to be made directly to the Issuing Bank as expressly provided herein and except that payments pursuant to Section 5.01, Section 5.02, Section 5.03 and Section 12.03 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment

- 40 -

hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments hereunder shall be made in dollars.

(b) Application of Insufficient Payments. If at any time prior the Termination Date, insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, unreimbursed LC Disbursements, interest, fees and other amounts then due hereunder, such funds shall be applied: first, ratably to reimbursement of expenses and indemnities provided for in this Agreement and the Security Instruments; second, to accrued interest on the Loans; third, to fees; fourth, pro rata to outstanding principal of the Loans and unreimbursed LC Disbursements; and fifth, if required by the terms of this Agreement, to serve as cash collateral to be held by the Administrative Agent to secure the LC Exposure; in each case, ratably among the parties entitled thereto in accordance with the amounts then due to such parties.

(c) Sharing of Payments by Lenders. If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans or participations in LC Disbursements resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and participations in LC Disbursements and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Loans and participations in LC Disbursements of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and participations in LC Disbursements; provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this Section 4.01(c) shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or participations in LC Disbursements to any assignee or participant, other than to a Loan Party or Affiliate thereof (as to which the provisions of this Section 4.01(c) shall apply). The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law and under this Agreement, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

Section 4.02 Presumption of Payment by the Borrower. Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders or the Issuing Bank that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders or the Issuing Bank, as the case may be, the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders or the Issuing Bank, as the case may be, severally agrees to repay to the Administrative Agent forthwith

- 41 -

on demand the amount so distributed to such Lender or Issuing Bank with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.

Section 4.03 Certain Deductions by the Administrative Agent. If any Lender shall fail to make any payment required to be made by it pursuant hereto then the Administrative Agent may, in its discretion (notwithstanding any contrary provision hereof), apply any amounts thereafter received by the Administrative Agent for the account of such Lender to satisfy such Lender’s obligations under such Sections until all such unsatisfied obligations are fully paid. If at any time prior to the acceleration or maturity of the Loans, the Administrative Agent shall receive any payment in respect of principal of a Loan or a reimbursement of an LC Disbursement while one or more Defaulting Lenders shall be party to this Agreement, the Administrative Agent shall apply such payment first to the Borrowing(s) for which such Defaulting Lender(s) shall have failed to fund its pro rata share until such time as such Borrowing(s) are paid in full or each Lender (including each Defaulting Lender) is owed its Applicable Percentage of all Loans then outstanding. After acceleration or maturity of the Loans, all principal will be paid ratably as provided in Section 10.02(c).

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

Increased Costs; Break Funding Payments; Taxes

Section 5.01 Increased Costs.

(a) Eurodollar Changes in Law. If any Change in Law shall:

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

- 42 -

(ii) impose on any Lender or the London interbank market any other condition (other than Excluded Taxes) affecting this Agreement or Eurodollar Loans made by such Lender;

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

(b) Capital Requirements. If any Lender or the Issuing Bank determines that any Change in Law regarding capital or liquidity requirements has or would have the effect of reducing the rate of return on such Lender’s or the Issuing Bank’s capital or on the capital of such Lender’s or the Issuing Bank’s holding company, if any, in each case by an amount deemed by such Lender to be material, as a consequence of this Agreement or the Loans made by, or participations in Letters of Credit held by, such Lender, or the Letters of Credit issued by the Issuing Bank, to a level below that which such Lender or the Issuing Bank or such Lender’s or the Issuing Bank’s holding company would have achieved but for such Change in Law (taking into consideration such Lender’s or the Issuing Bank’s policies and the policies of such Lender’s or the Issuing Bank’s holding company with respect to capital adequacy and liquidity), then from time to time the Borrower will pay to such Lender or the Issuing Bank such additional amount or amounts as will compensate such Lender or the Issuing Bank or such Lender’s or the Issuing Bank’s holding company for any such reduction suffered.

(c) Certificates. A certificate of a Lender or the Issuing Bank setting forth the amount or amounts necessary to compensate such Lender or the Issuing Bank or its holding company, as the case may be, as specified in Section 5.01(a) or (b) and reasonably detailed calculations therefor shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender or the Issuing Bank, as the case may be, the amount shown as due on any such certificate within 30 days after receipt thereof.

(d) Effect of Failure or Delay in Requesting Compensation. Failure or delay on the part of any Lender or Issuing Bank to demand compensation pursuant to this Section 5.01 shall not constitute a waiver of such Lender’s or the Issuing Bank’s right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender or the Issuing Bank pursuant to this Section 5.01 for any increased costs or reductions incurred more than 180 days prior to the date that such Lender or the Issuing Bank, as the case may be, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or the Issuing Bank’s intention to claim compensation therefor; provided further that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 180-day period referred to above shall be extended to include the period of retroactive effect thereof.

Section 5.02 Break Funding Payments. In the event of (a) the payment of any principal of any Eurodollar Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan into an ABR Loan other than on the last day of the Interest Period applicable thereto, or (c) the failure to

- 43 -

borrow, convert, continue or prepay any Eurodollar Loan on the date specified in any notice delivered pursuant hereto, or (d) the assignment of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto as a result of a request by the Borrower pursuant to Section 5.05, then, in any such event, the Borrower shall compensate each Lender for the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of interest which would have accrued on the principal amount of such Loan had such event not occurred, at the Adjusted LIBO Rate that would have been applicable to such Loan, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest which would accrue on such principal amount for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the eurodollar market.

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

Section 5.03 Taxes.

(a) Payments Free of Taxes. Any and all payments by or on account of any obligation of the Borrower or any Guarantor under any Loan Document shall be made free and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided that if the Borrower or any Guarantor shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (a) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 5.03(a)), the Administrative Agent, Lender or the Issuing Bank (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (b) the Borrower or such Guarantor shall make such deductions and (c) the Borrower or such Guarantor shall pay the full amount deducted to the relevant Governmental Authority in accordance with applicable law.

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

(c) Indemnification by the Borrower. The Borrower shall indemnify the Administrative Agent, each Lender and the Issuing Bank, within 10 days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent, such Lender or the Issuing Bank, as the case may be, on or with respect to any payment by or on account of any obligation of the Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section 5.03) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate of the Administrative Agent, a Lender or the Issuing Bank as to the amount of such payment or liability under this Section 5.03) shall be delivered to the Borrower and shall be conclusive absent manifest error.

- 44 -

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

(e) Status of Lenders.

In addition, any Lender, if reasonably requested by the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Section 5.03(e)(ii)(A), (ii)(B) and (ii)(D) below) shall not be required if in the Lender’s reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender.

(ii) Without limiting the generality of the foregoing,

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

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

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

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

- 46 -

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

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

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

(h) Tax Refunds. If the Administrative Agent or any Lender determines, in its sole discretion, that it has received a refund of any Taxes or Other Taxes as to which it has been indemnified by the Borrower or with respect to which the Borrower has paid additional amounts pursuant to this Section 5.03, it shall pay over such refund to the Borrower (but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section 5.03 with respect to the Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of the Administrative Agent or such Lender and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund); provided that the Borrower, upon the request of the Administrative Agent or such Lender, agrees to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to the Administrative Agent or such Lender in the event the Administrative Agent or such Lender is required to repay such refund to such Governmental Authority. This Section 5.03 shall not be construed to require the Administrative Agent or any Lender to make available its tax returns (or any other information relating to its taxes which it deems confidential) to the Borrower or any other Person.

- 47 -

(i) Survival. The agreements in this Section 5.03 shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder.

Section 5.04 Designation of Different Lending Office. If any Lender requests compensation under Section 5.01, or if the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 5.03, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (a) would eliminate or reduce amounts payable pursuant to Section 5.01 or Section 5.03, as the case may be, in the future and (b) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

Section 5.05 Replacement of Lenders. If (a) any Lender requests compensation under Section 5.01, (b) the Borrower is required to pay any additional amount to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 5.03, (c) any Lender becomes a Defaulting Lender, or (d) any Lender has not approved a proposed waiver or amendment requiring 100% approval or consent but which has been approved by Lenders holding 50% or more of the then outstanding Commitments, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 12.04(b)), all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (i) the Borrower shall have received the prior written consent of the Administrative Agent, which consent shall not unreasonably be withheld, (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and participations in LC Disbursements, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts), and (iii) in the case of any such assignment resulting from a claim for compensation under Section 5.01 or payments required to be made pursuant to Section 5.03, such assignment will result in a reduction in such compensation or payments.

Section 5.06 Illegality. Notwithstanding any other provision of this Agreement, in the event that it becomes unlawful for any Lender or its applicable lending office to honor its obligation to make or maintain Eurodollar Loans either generally or having a particular Interest Period hereunder, then (a) such Lender shall promptly notify the Borrower and the Administrative Agent thereof and such Lender’s obligation to make such Eurodollar Loans shall be suspended (the “Affected Loans”) until such time as such Lender may again make and maintain such Eurodollar Loans and (b) all Affected Loans which would otherwise be made by such Lender shall be made instead as ABR Loans (and, if such Lender so requests by notice to

- 48 -

the Borrower and the Administrative Agent, all Affected Loans of such Lender then outstanding shall be automatically converted into ABR Loans on the date specified by such Lender in such notice) and, to the extent that Affected Loans are so made as (or converted into) ABR Loans, all payments of principal which would otherwise be applied to such Lender’s Affected Loans shall be applied instead to its ABR Loans; provided that the Borrower shall not be required to make any payments pursuant to Section 5.02 as a result of the conversion of any Affected Loans under this Section 5.06.

ARTICLE XI

The Administrative Agent And The Issuing Bank

Section 11.01 Appointment and Authorization of Administrative Agent; Secured Swap Agreements.

(a) Each Lender hereby irrevocably (subject to Section 11.10) appoints, designates and authorizes the Administrative Agent to take such action on its behalf under the provisions of this Agreement and each other Loan Document and to exercise such powers and perform such duties as are expressly delegated to it by the terms of this Agreement or any other Loan Document, together with such powers as are reasonably incidental thereto. Notwithstanding any provision to the contrary contained elsewhere herein or in any other Loan Document, the Administrative Agent shall not have any duties or responsibilities, except those expressly set forth herein, nor shall the Administrative Agent have or be deemed to have any fiduciary relationship with any Lender or participant, 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. Without limiting the generality of the foregoing sentence, the use of the term “agent” herein and in the other Loan Documents with reference to the Administrative Agent, any syndication agent or documentation agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties.

(b) The Issuing Bank shall act on behalf of the Lenders with respect to any Letters of Credit issued by it and the documents associated therewith until such time (and except for so long) as the Administrative Agent may agree at the request of the Majority Lenders to act for the Issuing Bank with respect thereto; provided, however, that the Issuing Bank shall have all of the benefits and immunities (i) provided to the Administrative Agent in this Article XI with

- 83 -

respect to any acts taken or omissions suffered by the Issuing Bank in connection with Letters of Credit issued by it or proposed to be issued by it and the application and agreements for letters of credit pertaining to the Letters of Credit as fully as if the term “Administrative Agent” as used in this Article XI included the Issuing Bank with respect to such acts or omissions, and (ii) as additionally provided herein with respect to the Issuing Bank.

Section 11.02 Delegation of Duties. The Administrative Agent may execute any of its duties under this Agreement or any other Loan Document by or through agents, sub-agents, employees or attorneys in fact and shall be entitled to advice of counsel and other consultants or experts concerning all matters pertaining to such duties. The Administrative Agent shall not be responsible for the negligence or misconduct of any agent or attorney in fact that it selects in the absence of gross negligence or willful misconduct.

Section 11.03 Default; Collateral.

(a) Upon the occurrence and continuance of a Default or Event of Default, the Lenders agree to promptly confer in order that the Majority Lenders or the Lenders, as the case may be, may agree upon a course of action for the enforcement of the rights of the Lenders; and the Administrative Agent shall be entitled to refrain from taking any action (without incurring any liability to any Person for so refraining) unless and until the Administrative Agent shall have received instructions from the Majority Lenders or the Lenders, as the case may be. All rights of action under the Loan Documents and all right to the Collateral, if any, hereunder may be enforced by the Administrative Agent and any suit or proceeding instituted by the Administrative Agent in furtherance of such enforcement shall be brought in its name as the Administrative Agent without the necessity of joining as plaintiffs or defendants any other Lender, and the recovery of any judgment shall be for the benefit of the Lenders (and, with respect to Secured Swap Agreements and Bank Products, Affiliates, if applicable) subject to the expenses of the Administrative Agent. In actions with respect to any Property of the Borrower or any Restricted Subsidiary, the Administrative Agent is acting for the ratable benefit of each Lender (and, with respect to Secured Swap Agreements and Bank Products, Affiliates, if applicable). Any and all agreements to subordinate (whether made heretofore or hereafter) other indebtedness or obligations of Borrower to the Indebtedness shall be construed as being for the ratable benefit of each Lender (and, with respect to Secured Swap Agreements and Bank Products, Affiliates, if applicable).

(b) Each Lender authorizes and directs the Administrative Agent to enter into the Security Instruments on behalf of and for the benefit of the Lenders (and, with respect to Secured Swap Agreements and Bank Products, Affiliates, if applicable)(or if previously entered into, hereby ratifies the Administrative Agent’s (or any predecessor administrative agent’s) previously entering into such agreements and Security Instruments).

(c) Except to the extent unanimity (or other percentage set forth in Section 12.02) is required hereunder, each Lender agrees that any action taken by the Majority Lenders in accordance with the provisions of the Loan Documents, and the exercise by the Majority Lenders of the power set forth herein or therein, together with such other powers as are reasonably incidental thereto, shall be authorized and binding upon all of the Lenders.

- 84 -

(d) The Administrative Agent is hereby authorized on behalf of the Lenders, without the necessity of any notice to or further consent from any Lender, from time to time to take any action with respect to any Collateral or Security Instruments which may be necessary to perfect and maintain perfected the Liens upon the Collateral granted pursuant to the Security Instruments.

(e) The Administrative Agent shall not have any obligation whatsoever to any Lender or to any other Person to assure that the Collateral exists or is owned (whether in fee or by leasehold) by the Person purporting to own it or is cared for, protected, or insured or has been encumbered or that the Liens granted to the Administrative Agent (or any predecessor administrative agent) herein or pursuant thereto have been properly or sufficiently or lawfully created, perfected, protected, or enforced, or are entitled to any particular priority, or to exercise at all or in any particular manner or under any duty of care, disclosure, or fidelity, or to continue exercising, any of the rights granted or available to the Administrative Agent in this Section 11.03 or in any of the Security Instruments; IT BEING UNDERSTOOD AND AGREED THAT IN RESPECT OF THE COLLATERAL, OR ANY ACT, OMISSION, OR EVENT RELATED THERETO, THE ADMINISTRATIVE AGENT MAY ACT IN ANY MANNER IT MAY DEEM APPROPRIATE, IN ITS SOLE DISCRETION, GIVEN THE ADMINISTRATIVE AGENT’S OWN INTEREST IN THE COLLATERAL AS ONE OF THE LENDERS AND THAT THE ADMINISTRATIVE AGENT SHALL HAVE NO DUTY OR LIABILITY WHATSOEVER TO ANY LENDER (AND, WITH RESPECT TO SECURED SWAP AGREEMENTS AND BANK PRODUCTS, AFFILIATES), OTHER THAN TO ACT WITHOUT GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.

(f) The Lenders hereby irrevocably authorize the Administrative Agent, at its option and in its discretion, to release any Lien granted to or held by the Administrative Agent upon any Collateral: (A) constituting property in which neither Borrower nor any Restricted Subsidiary owned an interest at the time the Lien was granted or at any time thereafter; (B) constituting property leased to the Borrower or a Restricted Subsidiary under a lease which has expired or been terminated in a transaction permitted under the Loan Documents or is about to expire and which has not been, and is not intended by the Borrower or such Restricted Subsidiary to be, renewed; or (C) consisting of an instrument or other possessory collateral evidencing Debt or other obligations pledged to the Administrative Agent (for the benefit of the Lenders), if the Debt or obligations evidenced thereby has been paid in full or otherwise superseded. In addition, the Lenders irrevocably authorize the Administrative Agent to release Liens upon Collateral and to release any Guarantor from the Guaranty Agreement as contemplated herein and in the other Loan Documents, or if approved, authorized, or ratified in writing by the requisite Lenders. Upon request by the Administrative Agent at any time, the Lenders will confirm in writing the Administrative Agent’s authority to release particular types or items of Collateral pursuant to this Section 11.03.

(g) In furtherance of the authorizations set forth in this Section 11.03, each Lender hereby irrevocably appoints the Administrative Agent its attorney-in-fact, with full power of substitution, for and on behalf of and in the name of each such Lender (i) to enter into Security Instruments (including, without limitation, any appointments of substitute trustees under any Security Instruments), (ii) to take action with respect to the Collateral and Security Instruments to perfect, maintain, and preserve the Lenders’ Liens, and (iii) to execute instruments of release

- 85 -

or to take other action necessary to release Liens upon any Collateral to the extent authorized herein or in the other Loan Documents. This power of attorney shall be liberally, not restrictively, construed so as to give the greatest latitude to the Administrative Agent’s power, as attorney, relative to the Collateral matters described in this Section 11.03. The powers and authorities herein conferred on the Administrative Agent may be exercised by the Administrative Agent through any Person who, at the time of the execution of a particular instrument, is an officer of the Administrative Agent (or any Person acting on behalf of the Administrative Agent pursuant to a valid power of attorney). The power of attorney conferred by this Section 11.03(g) to the Administrative Agent is granted for valuable consideration and is coupled with an interest and is irrevocable so long as the Indebtedness, or any part thereof, shall remain unpaid or the Lenders are obligated to make any Loan or issue any Letter of Credit under the Loan Documents.

Section 11.04 Liability of Administrative Agent. NO RELATED PARTY OF THE ADMINISTRATIVE AGENT SHALL (A) BE LIABLE FOR ANY ACTION TAKEN OR OMITTED TO BE TAKEN BY ANY OF THEM UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (EXCEPT FOR ITS OWN GROSS NEGLIGENCE OR WILLFUL MISCONDUCT IN CONNECTION WITH ITS DUTIES EXPRESSLY SET FORTH HEREIN), or (b) be responsible in any manner to any Lender or participant for any recital, statement, representation or warranty made by the Borrower or any Restricted Subsidiary or any officer thereof, contained herein or in 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 the validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other Loan Document, or for the creation, perfection or priority of any Liens purported to be created by any of the Loan Documents, or the validity, genuineness, enforceability, existence, value or sufficiency of any collateral security, or to make any inquiry respecting the performance by the Borrower of its obligations hereunder or under any other Loan Document, or for any failure of the Borrower or any Restricted Subsidiary or any other party to any Loan Document to perform its obligations hereunder or thereunder. No Related Party of the Administrative Agent shall be under any obligation to any Lender or Participant 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 the Borrower or any Restricted Subsidiary or any Affiliate thereof.

Section 11.05 Reliance by Administrative Agent.

(a) The Administrative Agent shall be entitled to rely, and shall be fully protected in relying, upon any writing, communication, signature, resolution, representation, notice, consent, certificate, affidavit, letter, telegram, facsimile, electronic mail, or telephone message, statement 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 counsel to the Borrower or any Restricted Subsidiary), independent accountants and other experts selected by the Administrative Agent. The Administrative Agent shall be fully justified in failing or refusing to take any action under any Loan Document unless it shall first receive such advice or concurrence of the Majority Lenders as it deems appropriate and, if it so requests, it shall first be indemnified to its satisfaction by the

- 86 -

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 or any other Loan Document in accordance with a request or consent of the Majority Lenders or all the Lenders, if required hereunder, and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders and Participants. Where this Agreement expressly permits or prohibits an action unless the Majority Lenders or Super Majority Lenders otherwise determine, the Administrative Agent shall, and in all other instances, the Administrative Agent may, but shall not be required to, initiate any solicitation for the consent or a vote of the requisite Lenders.

(b) For purposes of determining compliance with the conditions specified in Section 6.01, each Lender that has funded its Applicable Percentage of the initial Loan on the Effective Date (or, if there is no Loan made on such date, each Lender other than the Lenders who gave written objection to the Administrative Agent prior to such date) shall be deemed to have consented to, approved or accepted, or to be satisfied with, each document or other matter either sent by the Administrative Agent to such Lender (or otherwise made available for such Lender on SyndTrak Online, DXSyndicate™ or any similar website) for consent, approval, acceptance or satisfaction, or required hereunder to be consented to or approved by or acceptable or satisfactory to a Lender.

Section 11.06 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, except with respect to defaults in the payment of principal, interest and fees required to be paid to the Administrative Agent for the account of the Lenders, unless the Administrative Agent shall have received written notice from a Lender or the Borrower referring to this Agreement, describing such Default or Event of Default and stating that such notice is a “notice of default.” The Administrative Agent will notify the Lenders of its receipt of any such notice. The Administrative Agent shall take such action with respect to such Default or Event of Default as may be directed by the Majority Lenders in accordance with this Agreement; provided, however, that unless and until the Administrative Agent has received any such direction, 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 or in the best interest of the Lenders.

Section 11.07 Credit Decision; Disclosure of Information by Administrative Agent. Each Lender acknowledges that no Related Party of the Administrative Agent has made any representation or warranty to it, and that no act by the Administrative Agent hereinafter taken, including any consent to and acceptance of any assignment or review of the affairs of the Borrower or any Restricted Subsidiary or any Affiliate thereof, shall be deemed to constitute any representation or warranty by any Related Party of the Administrative Agent to any Lender as to any matter, including whether Related Parties of the Administrative Agent have disclosed material information in their possession. Each Lender represents to the Administrative Agent that it has, independently and without reliance upon any Related Party of the Administrative Agent and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, prospects, operations, property, financial and other condition and creditworthiness of the Borrower, any Guarantor and their respective Subsidiaries, and all applicable bank or other regulatory laws relating to the transactions contemplated hereby, and made its own decision to enter into this Agreement and to extend credit

- 87 -

to the Borrower hereunder. Each Lender also represents that it will, independently and without reliance upon any Related Party of the Administrative Agent 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 investigations as it deems necessary to inform itself as to the business, prospects, operations, property, financial and other condition and creditworthiness of the Borrower and the other Loan Parties. In this regard, each Lender acknowledges that Vinson & Elkins L.L.P. is acting in this transaction as counsel to the Administrative Agent. Each other party hereto will consult with its own legal counsel to the extent that it deems necessary in connection with the Loan Documents and the matters contemplated therein. Except for notices, reports and other documents expressly required to be furnished to the Lenders by the Administrative Agent herein, the Administrative Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the business, prospects, operations, property, financial and other condition or creditworthiness of any of the Loan Parties or any of their respective Affiliates which may come into the possession of any Related Party of the Administrative Agent.

Section 11.08 Indemnification of Agents. WHETHER OR NOT THE TRANSACTIONS CONTEMPLATED HEREBY ARE CONSUMMATED, THE LENDERS SHALL INDEMNIFY UPON DEMAND EACH RELATED PARTY OF THE ADMINISTRATIVE AGENT (TO THE EXTENT NOT REIMBURSED BY OR ON BEHALF OF THE BORROWER AND WITHOUT LIMITING THE OBLIGATION OF THE BORROWER TO DO SO), IN ACCORDANCE WITH THEIR RESPECTIVE APPLICABLE PERCENTAGES, AND HOLD HARMLESS EACH RELATED PARTY OF THE ADMINISTRATIVE AGENT FROM AND AGAINST ANY AND ALL INDEMNIFIED LIABILITIES INCURRED BY IT (INCLUDING SUCH RELATED PARTY OF THE ADMINISTRATIVE AGENT’S OWN NEGLIGENCE); PROVIDED, HOWEVER, THAT NO LENDER SHALL BE LIABLE FOR THE PAYMENT TO ANY RELATED PARTY OF THE ADMINISTRATIVE AGENT OF ANY PORTION OF SUCH INDEMNIFIED LIABILITIES RESULTING FROM SUCH PERSON’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT; provided, however, that no action taken in accordance with the directions of the Majority Lenders shall be deemed to constitute gross negligence or willful misconduct for purposes of this Section 11.08. Without limitation of the foregoing, each Lender shall reimburse the Administrative Agent upon demand for its ratable share of any costs or out-of-pocket expenses (including counsel fees) incurred by the Administrative Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement, any other Loan Document, or any document contemplated by or referred to herein, to the extent that the Administrative Agent is not reimbursed for such expenses by or on behalf of the Borrower. The undertaking in this Section 11.08 shall survive termination of the Commitments, the payment of all Indebtedness hereunder and the resignation or replacement of the Administrative Agent.

Section 11.09 Administrative Agent in its Individual Capacity. Wells Fargo and its Affiliates may make loans to, accept deposits from, acquire equity interests in and generally engage in any kind of banking, trust, financial advisory, underwriting or other business with the Borrower and its Affiliates as though Wells Fargo were not the Administrative Agent or the

- 88 -

Issuing Bank hereunder and without notice to or consent of the Lenders. The Lenders acknowledge that, pursuant to such activities, Wells Fargo or its Affiliates may receive information regarding the Borrower or its Affiliates (including information that may be subject to confidentiality obligations in favor of the Borrower or such Affiliate) and acknowledge that the Administrative Agent shall be under no obligation to provide such information to them. With respect to its Loans, Wells Fargo shall have the same rights and powers under this Agreement as any other Lender and may exercise such rights and powers as though it were not the Administrative Agent or the Issuing Bank, and the terms “Lender” and “Lenders” include Wells Fargo in its individual capacity.

Section 11.10 Successor Administrative Agent and Issuing Bank. The Administrative Agent or the Issuing Bank may resign at any time upon 30 days’ notice to the Lenders with a copy of such notice to the Borrower. If the Administrative Agent or Issuing Bank resigns under this Agreement, the Majority Lenders shall appoint from among the Lenders a successor administrative agent or issuing bank for the Lenders which successor administrative agent or issuing bank shall be consented to by the Borrower at all times other than during the existence of an Event of Default (which consent of the Borrower shall not be unreasonably withheld, delayed or conditioned). If no successor administrative agent or issuing bank is appointed prior to the effective date of the resignation of the Administrative Agent or Issuing Bank, the Administrative Agent may appoint, after consulting with the Lenders and, so long as no Event of Default has occurred which is continuing, upon written approval of the Borrower (which approval of the Borrower shall not be unreasonably withheld, delayed or conditioned), a successor administrative agent and/or issuing bank from among the Lenders. Upon the acceptance of its appointment as successor administrative agent and/or issuing bank hereunder, such successor administrative agent and/or issuing bank shall succeed to all the rights, powers and duties of the retiring Administrative Agent or Issuing Bank and the term “Administrative Agent” and “Issuing Bank” shall mean such successor administrative agent or issuing bank and the retiring Administrative Agent’s or Issuing Bank’s appointment, powers and duties as Administrative Agent or Issuing Bank shall be terminated. The resigning Issuing Bank shall remain the Issuing Bank with respect to any Letters of Credit outstanding on the effective date of its resignation and the provisions affecting the Issuing Bank with respect to Letters of Credit shall inure to the benefit of the resigning Issuing Bank until the termination of all such Letters of Credit. After any retiring Administrative Agent’s resignation hereunder as Administrative Agent, the provisions of this Article XI and Sections 12.03 and 12.05 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. If no successor administrative agent has accepted appointment as Administrative Agent by the date which is 30 days following a retiring Administrative Agent’s notice of resignation, the retiring Administrative Agent’s resignation shall nevertheless thereupon become effective and the Lenders shall perform all of the duties of the Administrative Agent hereunder until such time, if any, as the Majority Lenders appoint a successor agent as provided for above; provided that in the case of any security held by the Administrative Agent on behalf of the Lenders or the Issuing Bank under the Loan Documents, the retiring Administrative Agent shall continue to hold such security until such time as a successor administrative agent is appointed.

Section 11.11 Syndication Agent; Other Agents; Arrangers. None of the Lenders or other Persons identified on the facing page or signature pages of this Agreement as a “syndication agent,” as a “co-documentation agent,” any other type of agent (other than the

- 89 -

Administrative Agent), “arranger,” or “bookrunner” shall have any right, power, obligation, liability, responsibility or duty under this Agreement other than those applicable to all Lenders as such. Without limiting the foregoing, none of the Lenders so identified shall have or be deemed to have any fiduciary relationship with any Lender. Each Lender acknowledges that it has not relied, and will not rely, on any of the Lenders so identified in deciding to enter into this Agreement or in taking or not taking action hereunder.

Section 11.12 Administrative Agent May File Proof of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Borrower or any Restricted Subsidiary, the Administrative Agent (irrespective of whether the principal of any Loan or LC Exposure shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent shall have made any demand on the Borrower) shall be entitled and empowered, by intervention in such proceeding or otherwise

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

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

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

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

Section 11.13 Secured Swap Agreements. To the extent any Affiliate of a Lender is a party to a Secured Swap Agreement with the Borrower or any of the Restricted Subsidiaries and thereby becomes a beneficiary of the Liens pursuant to any Security Instrument, 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 such Security Instruments and to be bound by the terms of this Article XI and the other provisions of this Agreement.

- 90 -

Section 11.14 Bank Product Obligations. To the extent any Affiliate of a Lender provides any Bank Products and thereby becomes a beneficiary of the Liens pursuant to any Security Instrument, 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 such Security Instruments and to be bound by the terms of this Article XI and the other provisions of this Agreement.

Section 12.02 Waivers; Amendments.

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

(b) Neither this Agreement nor any provision hereof nor any Security Instrument nor any provision thereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Loan Parties party thereto and the Majority Lenders or by the Borrower and the Administrative Agent with the consent of the Majority Lenders; provided that no such agreement shall

(i) increase the Maximum Credit Amount of any Lender without the written consent of such Lender,

(ii) increase the advance rates used in the definitions of “APL Borrowing Base Component” or “ARP Borrowing Base Component” or otherwise change any of

- 92 -

other definitions used directly or indirectly in the calculation of the Borrowing Base if any such change would result in an increase in the Borrowing Base without the written consent of all Lenders (other than any Defaulting Lender),

(iii) reduce the principal amount of any Loan or LC Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of each Lender directly and adversely affected thereby,

(iv) postpone the scheduled date of payment of the principal amount of any Loan or LC Disbursement, or any interest thereon, or any fees payable hereunder, or reduce the amount of, waive or excuse any such payment, or postpone or extend the Termination Date without the written consent of each Lender directly and adversely affected thereby,

(v) change Section 4.01(b) or Section 4.01(c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender adversely affected thereby,

(vi) release any Guarantor (except as set forth in the Guaranty Agreement) or release all or substantially all of the Collateral, without the written consent of each Lender (other than any Defaulting Lender), or

(vii) change any of the provisions of this Section 12.02(b) or the definitions of “Super Majority Lenders” or “Majority Lenders”, or Section 9.11(f) or any other provision hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or under any other Loan Documents or make any determination or grant any consent hereunder or any other Loan Documents, without the written consent of each Lender directly and adversely affected thereby;

provided further, that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent or the Issuing Bank hereunder or under any other Loan Document without the prior written consent of the Administrative Agent or the Issuing Bank, as the case may be. Notwithstanding the foregoing, any supplement to Schedule 7.15 (Subsidiaries) shall be effective simply by delivering to the Administrative Agent a supplemental schedule clearly marked as such and, upon receipt, the Administrative Agent will promptly deliver a copy thereof to the Lenders.

Section 12.03 Expenses, Indemnity; Damage Waiver.

(a) The Borrower shall pay (i) all reasonable and documented out-of-pocket expenses incurred by the Administrative Agent and its Affiliates, including, without limitation, the reasonable fees, charges and disbursements of counsel and other outside consultants for the Administrative Agent, the reasonable travel, photocopy, mailing, courier, telephone and other similar expenses, and the cost of environmental audits and surveys and appraisals, in connection with the syndication of the credit facilities provided for herein, the preparation, negotiation, execution, delivery and administration (both before and after the execution hereof and including advice of counsel to the Administrative Agent as to the rights and duties of the Administrative Agent and the Lenders with respect thereto) of this Agreement and the other Loan Documents and any amendments, modifications or waivers of or consents related to the provisions hereof or

- 93 -

thereof (whether or not the transactions contemplated hereby or thereby shall be consummated), (ii) all reasonable and documented out-of-pocket costs, expenses, taxes, assessments and other charges incurred by the Administrative Agent or any Lender in connection with any filing, registration, recording or perfection of any security interest contemplated by this Agreement or any Security Instrument or any other document referred to therein, and (iii) all out-of-pocket expenses incurred by the Administrative Agent or any Lender, including the fees, charges and disbursements of any counsel for the Administrative Agent, the Issuing Bank or any Lender, in connection with the enforcement or protection of its rights in connection with this Agreement or any other Loan Document, including its rights under this Section 12.03, or in connection with the Loans made or Letters of Credit issued hereunder, including, without limitation, all such out-of-pocket expenses incurred during any workout, restructuring or similar negotiations in respect of such Loans or Letters of Credit.

(b) THE BORROWER SHALL INDEMNIFY THE ARRANGERS, THE ADMINISTRATIVE AGENT, THE ISSUING BANK AND EACH LENDER, AND EACH RELATED PARTY OF ANY OF THE FOREGOING PERSONS (EACH SUCH PERSON BEING CALLED AN “INDEMNITEE”) AGAINST, DEFEND AND HOLD EACH INDEMNITEE HARMLESS FROM, ANY AND ALL LOSSES, CLAIMS, DAMAGES, PENALTIES, LIABILITIES AND RELATED EXPENSES, INCLUDING THE REASONABLE FEES, CHARGES AND DISBURSEMENTS OF ANY COUNSEL FOR ANY INDEMNITEE, INCURRED BY OR ASSERTED AGAINST ANY INDEMNITEE ARISING OUT OF, IN CONNECTION WITH, OR AS A RESULT OF (1) THE EXECUTION OR DELIVERY OF THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR ANY AGREEMENT OR INSTRUMENT CONTEMPLATED HEREBY OR THEREBY, THE PERFORMANCE BY THE PARTIES HERETO OR THE PARTIES TO ANY OTHER LOAN DOCUMENT OF THEIR RESPECTIVE OBLIGATIONS HEREUNDER OR THEREUNDER OR THE CONSUMMATION OF THE TRANSACTIONS CONTEMPLATED HEREBY OR BY ANY OTHER LOAN DOCUMENT, (2) THE FAILURE OF THE BORROWER OR ANY RESTRICTED SUBSIDIARY TO COMPLY WITH THE TERMS OF ANY LOAN DOCUMENT, INCLUDING THIS AGREEMENT, OR WITH ANY LAW, (3) ANY INACCURACY OF ANY REPRESENTATION OR ANY BREACH OF ANY WARRANTY OR COVENANT OF THE BORROWER OR ANY GUARANTOR SET FORTH IN ANY OF THE LOAN DOCUMENTS OR ANY INSTRUMENTS, DOCUMENTS OR CERTIFICATIONS DELIVERED IN CONNECTION THEREWITH, (4) ANY LOAN OR LETTER OF CREDIT OR THE USE OF THE PROCEEDS THEREFROM, INCLUDING, WITHOUT LIMITATION, (a) ANY REFUSAL BY THE ISSUING BANK TO HONOR A DEMAND FOR PAYMENT UNDER A LETTER OF CREDIT IF THE DOCUMENTS PRESENTED IN CONNECTION WITH SUCH DEMAND DO NOT STRICTLY COMPLY WITH THE TERMS OF SUCH LETTER OF CREDIT, OR (b) THE PAYMENT OF A DRAWING UNDER ANY LETTER OF CREDIT NOTWITHSTANDING THE NON-COMPLIANCE, NON-DELIVERY OR OTHER IMPROPER PRESENTATION OF THE DOCUMENTS PRESENTED IN CONNECTION THEREWITH, (5) ANY OTHER ASPECT OF THE LOAN DOCUMENTS, (6) THE OPERATIONS OF THE BUSINESS OF THE BORROWER AND THE RESTRICTED SUBSIDIARIES, (7) ANY ASSERTION THAT THE LENDERS WERE NOT ENTITLED TO RECEIVE THE PROCEEDS RECEIVED PURSUANT TO THE SECURITY INSTRUMENTS, (8) ANY ENVIRONMENTAL LAW

- 94 -

APPLICABLE TO THE BORROWER OR ANY RESTRICTED SUBSIDIARY OR ANY OF THEIR PROPERTIES, INCLUDING WITHOUT LIMITATION, THE PRESENCE, GENERATION, STORAGE, RELEASE, THREATENED RELEASE, USE, TRANSPORT, DISPOSAL, ARRANGEMENT OF DISPOSAL OR TREATMENT OF OIL, OIL AND GAS WASTES, SOLID WASTES OR HAZARDOUS SUBSTANCES ON ANY OF THEIR PROPERTIES, (9) THE BREACH OR NON-COMPLIANCE BY THE BORROWER OR ANY RESTRICTED SUBSIDIARY WITH ANY ENVIRONMENTAL LAW APPLICABLE TO THE BORROWER OR ANY RESTRICTED SUBSIDIARY, (10) THE PAST OWNERSHIP BY THE BORROWER OR ANY RESTRICTED SUBSIDIARY OF ANY OF THEIR PROPERTIES OR PAST ACTIVITY ON ANY OF THEIR PROPERTIES WHICH, THOUGH LAWFUL AND FULLY PERMISSIBLE AT THE TIME, COULD RESULT IN PRESENT LIABILITY, (11) THE PRESENCE, USE, RELEASE, STORAGE, TREATMENT, DISPOSAL, GENERATION, THREATENED RELEASE, TRANSPORT, ARRANGEMENT FOR TRANSPORT OR ARRANGEMENT FOR DISPOSAL OF OIL, OIL AND GAS WASTES, SOLID WASTES OR HAZARDOUS SUBSTANCES ON OR AT ANY OF THE PROPERTIES OWNED OR OPERATED BY THE BORROWER OR ANY RESTRICTED SUBSIDIARY OR ANY ACTUAL OR ALLEGED PRESENCE OR RELEASE OF HAZARDOUS MATERIALS ON OR FROM ANY PROPERTY OWNED OR OPERATED BY THE BORROWER OR ANY OF THE RESTRICTED SUBSIDIARIES, (12) ANY ENVIRONMENTAL LIABILITY RELATED IN ANY WAY TO THE BORROWER OR ANY OF THE RESTRICTED SUBSIDIARIES, OR (13) ANY OTHER ENVIRONMENTAL, HEALTH OR SAFETY CONDITION IN CONNECTION WITH THE LOAN DOCUMENTS, OR (14) ANY ACTUAL OR PROSPECTIVE CLAIM, LITIGATION, INVESTIGATION OR PROCEEDING RELATING TO ANY OF THE FOREGOING, WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY AND REGARDLESS OF WHETHER ANY INDEMNITEE IS A PARTY THERETO, AND SUCH INDEMNITY SHALL EXTEND TO EACH INDEMNITEE NOTWITHSTANDING THE SOLE OR CONCURRENT NEGLIGENCE OF EVERY KIND OR CHARACTER WHATSOEVER, WHETHER ACTIVE OR PASSIVE, WHETHER AN AFFIRMATIVE ACT OR AN OMISSION, INCLUDING WITHOUT LIMITATION, ALL TYPES OF NEGLIGENT CONDUCT IDENTIFIED IN THE RESTATEMENT (SECOND) OF TORTS OF ONE OR MORE OF THE INDEMNITEES OR BY REASON OF STRICT LIABILITY IMPOSED WITHOUT FAULT ON ANY ONE OR MORE OF THE INDEMNITEES; PROVIDED THAT SUCH INDEMNITY SHALL NOT, AS TO ANY INDEMNITEE, BE AVAILABLE TO THE EXTENT THAT SUCH LOSSES, CLAIMS, DAMAGES, LIABILITIES OR RELATED EXPENSES HAVE RESULTED FROM (A) THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF SUCH INDEMNITEE (AS DETERMINED BY A FINAL, NONAPPEALABLE JUDGMENT OF A COURT OF COMPETENT JURISDICTION), (B) A MATERIAL BREACH OF THE MATERIAL OBLIGATIONS OF SUCH INDEMNITEE UNDER THE LOAN DOCUMENTS OR (C) ANY PROCEEDING THAT IS SOLELY AMONG INDEMNITEES.

- 95 -

unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent or the Issuing Bank in its capacity as such.

(d) To the extent permitted by applicable law, the Borrower shall not assert, and hereby waives, any claim against any indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any other Loan Document or any agreement or instrument contemplated hereby or thereby, the Transactions, any Loan or Letter of Credit or the use of the proceeds thereof.

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

Section 12.04 Successors and Assigns.

Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby (including any Affiliate of the Issuing Bank that issues any Letter of Credit), Participants (to the extent provided in Section 12.04(c)) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent, the Issuing Bank, and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) (i) Subject to the conditions set forth in paragraph (b)(ii) below, any Lender may assign to one or more assignees (each, an “Assignee”) all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it) with the prior written consent of:

(A) the Borrower (such consent not to be unreasonably withheld, conditioned or delayed), provided that no consent of the Borrower shall be required for an assignment to a Lender, an Affiliate of a Lender, an Approved Fund (as defined below) or, if an Event of Default has occurred and is continuing, any other Person; and

(B) the Administrative Agent and the Issuing Bank (such consent not to be unreasonably withheld, conditioned or delayed), provided that no consent of the Administrative Agent or the Issuing Bank shall be required for an assignment to a Lender, an Affiliate of a Lender, or an Approved Fund.

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

- 96 -

(A) except in the case of an assignment to a Lender, an affiliate of a Lender or an Approved Fund or an assignment of the entire remaining amount of the assigning Lender’s Commitment or Loans, the amount of the Commitment or Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent) shall not be less than $5,000,000 or, if smaller, the entire remaining amount of the assigning Lender’s Maximum Credit Amount, unless each of the Borrower and the Administrative Agent otherwise consent, provided that (1) no such consent of the Borrower shall be required if an Event of Default has occurred and is continuing and (2) such amounts shall be aggregated in respect of each Lender and its Affiliates or Approved Funds, if any;

(B) the parties to each assignment (other than assignments to an Affiliate of a Lender or an Approved Fund) shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500 unless such fee is waived by the Administrative Agent;

(C) the Assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire; and

(iii) Subject to acceptance and recording thereof pursuant to paragraph (b)(iv) below, from and after the effective date specified in each Assignment and Assumption the Assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Section 5.01, Section 5.02, Section 5.03 and Section 12.03). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 12.04(b) shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with Section 12.04(c).

(iv) The Administrative Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Maximum Credit Amount of, and principal amount of the Loans and LC Exposures owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent, the

- 97 -

Issuing Bank and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower, the Issuing Bank and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(v) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an Assignee, the Assignee’s completed Administrative Questionnaire (unless the Assignee shall already be a Lender hereunder), the processing and recordation fee referred to in Section 12.04(b), and any written consent to such assignment required by Section 12.04(b), the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the Register. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this Section 12.04(b).

(c) (i) Any Lender may, without the consent of the Borrower or the Administrative Agent, sell participations to one or more banks or other entities other than the Borrower or any Affiliate of the Borrower (each a “Participant”) in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans owing to it); provided that (A) such Lender’s obligations under this Agreement shall remain unchanged, (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, and (C) the Borrower, the Administrative Agent, the Issuing Bank and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver that (1) requires the consent of each Lender directly affected thereby pursuant to Section 12.02(b) and (2) directly affects such Participant. Subject to paragraph (c)(ii) of this Section, the Borrower agrees that each Participant shall be entitled to the benefits of Section 5.01, Section 5.02, and Section 5.03 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to Section 12.04(b). To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 12.08 as though it were a Lender, provided such Participant shall be subject to Section 4.01 as though it were a Lender. Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Loans or other obligations under the Loan Documents (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant’s interest in any commitments, loans, letters of credit or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such commitment, loan, letter of credit or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement

- 98 -

notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrative Agent (in its capacity as Administrative Agent) shall have no responsibility for maintaining a Participant Register.

(ii) A Participant shall not be entitled to receive any greater payment under Section 5.01 or Section 5.03 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the Borrower’s prior written consent. Any Participant that is a Foreign Lender shall not be entitled to the benefits of Section 5.03 unless the Borrower is notified of the participation sold to such Participant and such Participant agrees, for the benefit of the Borrower, to comply with Section 5.03(e).

(d) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section shall not apply to any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or Assignee for such Lender as a party hereto.

(e) Notwithstanding the foregoing, any Lender may grant to a Conduit Lender the option to provide to the Borrower all or any part of any Loan that a Lender would be required to make, and any Conduit Lender may assign any or all of the Loans it may have funded hereunder to its designating Lender, in each case, without the consent of the Borrower or the Administrative Agent and without regard to the limitations set forth in Section 12.04(b). Each of the Borrower, each Lender and the Administrative Agent hereby confirms that it will not institute against a Conduit Lender or join any other Person in instituting against a Conduit Lender any bankruptcy, reorganization, arrangement, insolvency or liquidation proceeding under any state bankruptcy or similar law, for one year and one day after the payment in full of the latest maturing commercial paper note issued by such Conduit Lender; provided, however, that each Lender designating any Conduit Lender hereby agrees to indemnify, save and hold harmless each other party hereto for any loss, cost, damage or expense arising out of its inability to institute such a proceeding against such Conduit Lender during such period of forbearance.

Section 12.05 Survival; Revival; Reinstatement.

(a) All covenants, agreements, representations and warranties made by the Borrower herein and by the Restricted Subsidiaries in the certificates or other instruments delivered in connection with or pursuant to this Agreement or any other Loan Document shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of this Agreement and the making of any Loans and issuance of any Letters of Credit regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent, the Issuing Bank or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Commitments have not expired or terminated. The provisions of Section 5.01, Section 5.02, Section 5.03 and

- 99 -

Section 12.03 and ARTICLE XI shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Letters of Credit and the Commitments or the termination of this Agreement, any other Loan Document or any provision hereof or thereof.

(b) To the extent any payment by or on behalf of the Borrower is made to the Administrative Agent, the Issuing Bank or any Lender, and such payment or any part thereof is subsequently invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by the Administrative Agent, the Issuing Bank or any Lender in its discretion) to be repaid to a trustee, receiver or any other party, in connection with any proceeding under any bankruptcy or other laws for the relief of debtors or otherwise, then to the extent of such recovery, the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made.

Section 12.06 Counterparts; Integration; Effectiveness.

(a) This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract.

(b) This Agreement, the other Loan Documents and any separate letter agreements with respect to fees payable to the Administrative Agent constitute the entire contract among the parties relating to the subject matter hereof and thereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof and thereof. This Agreement and the other Loan Documents represent the final agreement among the parties hereto and thereto and may not be contradicted by evidence of prior, contemporaneous or subsequent oral agreements of the parties. There are no unwritten oral agreements between the parties.

(c) Except as provided in Section 6.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement by email (in .pdf or similar format) or telecopy shall be effective as delivery of a manually executed counterpart of this Agreement.

Section 12.07 Severability. Any provision of this Agreement or any other Loan Document held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof or thereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

Section 12.08 Right of Setoff. If an Event of Default under Section 10.01(a) or Section 10.01(b) shall have occurred and be continuing, each Lender and each of its Affiliates is hereby

- 100 -

authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other obligations (of whatsoever kind, including, without limitations obligations under Swap Agreements) at any time owing by such Lender or Affiliate to or for the credit or the account of the Borrower or any Restricted Subsidiary against any of and all the obligations of the Borrower or any Restricted Subsidiary owed to such Lender now or hereafter existing under this Agreement or any other Loan Document, irrespective of whether or not such Lender shall have made any demand under this Agreement or any other Loan Document and although such obligations may be unmatured. Such Lender shall promptly notify the Borrower after any such set off and application made by such Lender, but the failure to give such notice will not affect the validity of such set off and application. The rights of each Lender under this Section 12.08 are in addition to other rights and remedies (including other rights of setoff) which such Lender or its Affiliates may have.

Section 12.11 Confidentiality. Each of the Administrative Agent and each Lender agrees to keep confidential all non-public information provided to it by the Borrower or any of the Restricted Subsidiaries, the Administrative Agent or any Lender pursuant to or in connection with this Agreement that is designated by the provider thereof as confidential; provided that nothing herein shall prevent the Administrative Agent or any Lender from disclosing any such information (a) to the Administrative Agent, any other Lender or any affiliate thereof (subject, in the case of such disclosure to any affiliate of the Administrative Agent or a Lender, to the Administrative Agent or such Lender, as applicable, being responsible for compliance by such affiliate with the provisions of this Section 12.11), (b) subject to an agreement to comply with the provisions of this Section, to any actual or prospective Transferee or any direct or indirect counterparty to any Swap Agreement (or any professional advisor to such counterparty), (c) to its employees, directors, agents, attorneys, accountants and other professional advisors or those of any of its affiliates (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), (d) upon the request or demand of any Governmental Authority or self-regulatory bodies that claim oversight over the Administrative Agent, the Issuing Bank, any Arranger or their respective Affiliates or businesses, (e) in response to any order of any court or other Governmental Authority or as may otherwise be required pursuant to any Law, (f) if requested or required to do so in connection with any litigation or similar proceeding, (g) that has been publicly disclosed, (h) to the National Association of Insurance Commissioners or any similar organization or any nationally recognized rating agency that requires access to information about a Lender’s investment portfolio in connection with ratings issued with respect to such Lender, or (i) in connection with the exercise of any remedy hereunder or under any other Loan Document.

- 102 -

Each Lender acknowledges that information furnished to it pursuant to this Agreement or the other Loan Documents may include material non-public information concerning the Borrower and its Affiliates and their related parties or their respective securities, and confirms that it has developed compliance procedures regarding the use of material non-public information and that it will handle such material non-public information in accordance with those procedures and applicable law, including Federal and state securities laws.

All information, including requests for waivers and amendments, furnished by the Borrower or the Administrative Agent pursuant to, or in the course of administering, this Agreement or the other Loan Documents will be syndicate-level information, which may contain material non-public information about the Borrower and its Affiliates and their related parties or their respective securities. Accordingly, each Lender represents to the Borrower and the Administrative Agent that it has identified in its Administrative Questionnaire a credit contact who may receive information that may contain material non-public information in accordance with its compliance procedures and applicable law, including Federal and state securities laws.

Section 12.12 Interest Rate Limitation. It is the intention of the parties hereto that each Lender shall conform strictly to usury laws applicable to it. Notwithstanding anything herein to the contrary, if at any time the interest rate applicable to any Loan, together with all fees, charges and other amounts which are treated as interest on such Loan under applicable law (collectively the “Charges”), shall exceed the maximum lawful rate (the “Maximum Rate”) which may be contracted for, charged, taken, received or reserved by the Lender holding such Loan in accordance with applicable law, the rate of interest payable in respect of such Loan, together with all Charges payable in respect thereof, shall be limited to the Maximum Rate and, to the extent lawful, the interest and Charges that would have been payable in respect of such Loan but were not payable as a result of the operation of this Section shall be cumulated and the interest and Charges payable to such Lender in respect of other Loans or periods shall be increased (but not above the Maximum Rate therefor) until such cumulated amount, together with interest thereon at the Federal Funds Effective Rate to the date of repayment, shall have been received by such Lender.

There are no third party beneficiaries.

Section 12.14 Collateral Matters; Swap Agreements. The benefit of the Security Instruments and of the provisions of this Agreement relating to any collateral securing the Indebtedness shall also extend to and be available to those Lenders or their Affiliates which are counterparties to any Secured Swap Agreement with the Borrower or any of the Restricted Subsidiaries on a pro rata basis in respect of any obligations of the Borrower or any of the Restricted Subsidiaries which arise under any such Secured Swap Agreement while such Person or its Affiliate is a Lender. For the avoidance of doubt, the obligations under any such Secured Swap Agreement will continue to be secured if the Person that is a counterparty to such Secured

- 103 -

Swap Agreement ceases to be a Lender or an Affiliate of a Lender, subject to the limitations set forth in the definition of “Secured Swap Agreement”. No Lender or any Affiliate of a Lender shall have any voting rights under any Loan Document as a result of the existence of obligations owed to it under any Swap Agreements.
