The Lenders shall participate in such Letters of Credit according to their respective Percentage Shares. Each of the Letters of Credit shall (i) be issued by Issuing Bank, (ii) contain such terms and provisions as are reasonably required by Issuing Bank, including a term of not more than one year from the date of issuance, (iii) be for the account of Borrower or a Subsidiary and (iv) expire not later than five (5) days before the Revolving Credit Termination Date.

(b) Mandatory Prepayments.

(i) Termination or Reduction of Aggregate Maximum Credit Amounts. If, after giving effect to any termination or reduction of the Aggregate Maximum Credit Amounts pursuant to Section 2.03(b), the outstanding aggregate principal amount of the Revolving Credit Loans plus the LC Exposure exceeds the Aggregate Maximum Credit Amounts, Borrower shall (i) prepay the Loans on the date of such termination or reduction in an aggregate principal amount equal to the excess, together with interest on the principal amount paid accrued to the date of such prepayment and (ii) if any excess remains after prepaying all of the Loans because of LC Exposure, pay to Agent on behalf of the Lenders an amount equal to the excess to be held as cash collateral as provided in Section 2.10(b) hereof.

(ii) Redetermination of Borrowing Base. Upon any redetermination of the amount of the Borrowing Base in accordance with Section 2.08, if the redetermined Borrowing Base results in a Borrowing Base Deficiency, then Borrower shall within thirty (30) days of receipt of written notice thereof (w) prepay the Loans in an aggregate principal amount sufficient to eliminate such Borrowing Base Deficiency (together with interest on the principal amount paid accrued to the date of such prepayment), (x) grant to Agent a first priority Lien on additional Properties of Borrower, which in the Lenders’ sole determination, have sufficient value to eliminate such Borrowing Base Deficiency, (y) elect to make a payment equal to one-sixth of such Borrowing Base Deficiency (together with interest on the principal amount paid accrued to the date of such prepayment) on such election date and on the corresponding day of the month in each five (5) consecutive months occurring after the month of such election date (provided that if any such month does not have a corresponding day, then with respect to such month(s), the last day of the month shall be deemed to be such corresponding day and if any corresponding day is not a Business Day, then the immediately succeeding Business Day shall be deemed to be such corresponding day) or (z) eliminate the Borrowing Base Deficiency through a combination of the actions described in clauses (w), (x) and (y). If, because of LC Exposure, a Borrowing Base Deficiency remains after prepaying all of the Loans and granting first priority Liens in additional Properties to Agent, Borrower shall pay to Agent on behalf of the Lenders an amount equal to such remaining Borrowing Base Deficiency to be held as cash collateral as provided in Section 2.10(b).

(iii) Monthly Reduction Amount. If any reduction of the amount of the Borrowing Base by operation of the Monthly Reduction Amount in accordance with Section 2.08 results in a Borrowing Base Deficiency, then Borrower shall immediately prepay the Loans in an aggregate principal amount equal to such Borrowing Base Deficiency, together with interest on the principal amount paid accrued to the date of such prepayment. If, because of LC Exposure, a Borrowing Base Deficiency remains after prepaying all of the Loans, Borrower shall pay to Agent on behalf of the Lenders an amount equal to such remaining Borrowing Base Deficiency to be held as cash collateral as provided in Section 2.10(b).

(iv) Transfer. If, after a Transfer of any Property to the extent allowed by Section 9.13 and the reduction in the Borrowing Base pursuant to Section 2.08(f), a Borrowing Base Deficiency exists, then Borrower shall, concurrently with the receipt thereof, prepay the Loans with the net proceeds received from such Transfer in an amount necessary to eliminate such Borrowing Base Deficiency. If, because of LC Exposure, a Borrowing Base Deficiency remains after prepaying all of the Loans, Borrower shall pay to Agent on behalf of the Lenders an amount equal to such remaining Borrowing Base Deficiency to be held as cash collateral as provided in Section 2.10(b). Notwithstanding anything in this Agreement to the contrary, if at the time of any permitted Transfer a Borrowing Base Deficiency exists, then Borrower shall, concurrently with the receipt thereof, prepay the Loans with the net proceeds received from such Transfer to the extent necessary to eliminate the portion of the Borrowing Base Deficiency resulting from such Transfer and such preexisting Borrowing Base Deficiency; and Borrower shall remain obligated, pursuant to the terms of this Agreement, to eliminate any Borrowing Base Deficiency remaining after prepaying the Loans with the net proceeds from such Transfer. If Borrower Transfers any Property at such time as a Default exits, Borrower shall, concurrently with the receipt of proceeds therefrom, prepay the Loans in an amount equal to the lesser of (x) the aggregate principal amount outstanding on the Loans and (y) 100% of the net proceeds received

from such Transfer. The preceding sentence shall not be interpreted as permitting the sale of any Property at such time as a Default exists without the prior written consent of the Lenders.

(v) Proceeds from Hedging Agreements. At any time that a Default exists, any proceeds received by Borrower under any Hedging Agreements, including as a result of the termination or early termination thereof, shall be used immediately upon receipt thereof to prepay the Loans in an amount equal to the lesser of (x) the aggregate principal amount outstanding on the Loans and (y) 100% of the net proceeds received.

(vi) Triggering Event. Upon each reduction of the Borrowing Base under Section 2.08(g) from the occurrence of a Triggering Event, if a Borrowing Base Deficiency then exists or results therefrom, then Borrower shall prepay the Loans or, if the Loans have been repaid in full, pay to Agent on behalf of the Lenders an amount equal to the excess to be held as cash collateral as provided in Section 2.10(b) hereof, in an amount equal to (A) such portion of the Borrowing Base Deficiency resulting from such reduction plus (B) if a Borrowing Base Deficiency exists prior to such reduction, then an amount equal to the lesser of (i) the net cash proceeds of such Triggering Event and (ii) such portion of the Borrowing Base Deficiency in existence immediately prior to such reduction.

(c) Generally. Prepayments permitted or required under this Section 2.07 shall be without premium or penalty except as required under Section 5.05 for prepayment of LIBOR Loans. Any prepayments on the Loans may be reborrowed subject to the then effective Aggregate Commitments.

Section 2.08 Borrowing Base.

(a) Borrowing Base and Monthly Reduction Amount. The Borrowing Base and the Monthly Reduction Amount shall be determined in accordance with Section 2.08(b) by Agent and the Majority Lenders (in the case of any reaffirmation or decrease in the Borrowing Base or reaffirmation or increase in the Monthly Reduction Amount) or Agent and all of the Lenders (in the case of any increase in the Borrowing Base or decrease in the Monthly Reduction Amount) and are subject to redetermination in accordance with Sections 2.08(d), (e) and (f). Upon any redetermination of the Borrowing Base or the Monthly Reduction Amount, such redetermination shall remain in effect until the next successive Redetermination Date; provided, however, the then effective Borrowing Base shall reduce on the last day of each month by the then effective Monthly Reduction Amount. So long as any of the Commitments are in effect or any LC Exposure or Loans are outstanding hereunder, this facility shall be governed by the then effective Borrowing Base and Monthly Reduction Amount. During the period from and after the Closing Date until the next redetermination pursuant to Sections 2.08(d), (e) or (f) or adjusted pursuant to Section 8.08(c), the amount of the Borrowing Base shall be $80,000,000, as reduced on a cumulative basis on the last day of each month following such effective date by the applicable

Monthly Reduction Amount. The Monthly Reduction Amount shall be $0 (zero dollars) each month until the next redetermination thereof pursuant to Sections 2.08(d), (e) or (f). No delay for any reason whatsoever in a redetermination of the Monthly Reduction Amount shall affect Borrower’s obligations under Section 2.07(b)(iii).

(b) Determination Procedure. Upon receipt of the reports required by Section 8.07 and such other reports, data and supplemental information as may from time to time be reasonably requested by Agent (the “Engineering Reports”), Agent and the Majority Lenders (in the case of any reaffirmation or decrease in the Borrowing Base or reaffirmation or increase in the Monthly Reduction Amount) or Agent and all of the Lenders (in the case of any increase in the Borrowing Base or decrease in the Monthly Reduction Amount) will redetermine the Borrowing Base and the Monthly Reduction Amount. Such redetermination will be in accordance with their normal and customary practices and procedures for evaluating oil and gas reserves and other related assets as such exist at that particular time, and may also take into consideration the financial condition, Debt, and business of Borrower and its Subsidiaries and such other factors as Agent customarily deems appropriate. Agent, in its sole discretion, may make adjustments to the rates, volumes and prices and other assumptions set forth therein in accordance with its normal and customary procedures for evaluating oil and gas reserves and other related assets as such exist at that particular time. Agent shall propose to the Lenders a new Borrowing Base and Monthly Reduction Amount within 15 days following receipt by Agent and the Lenders of the Engineering Reports in a timely and complete manner. After having received notice of such proposal by Agent, the Majority Lenders (in the case of any reaffirmation or decrease in the Borrowing Base or reaffirmation or increase in the Monthly Reduction Amount) or all of the Lenders (in the case of any increase in the Borrowing Base or decrease in the Monthly Reduction Amount) shall have 15 days to agree or disagree with such proposal. If the Majority Lenders notify Agent within 15 days of their disapproval of a proposed reaffirmation, decrease or increase in the Borrowing Base and/or reaffirmation, decrease or increase in the Monthly Reduction Amount, the Majority Lenders shall, within a reasonable period of time, agree on a new Borrowing Base and Monthly Reduction Amount. Notwithstanding anything herein to the contrary, Agent and all of the Lenders must approve any increase in the Borrowing Base and any reduction in the Monthly Reduction Amount.

(c) Excluded Property. Agent may exclude any Oil and Gas Property or portion of production therefrom or any income from any other Property from the Borrowing Base, at any time, because title and/or environmental information is not reasonably satisfactory, such Property is not Mortgaged Property or such Property is not assignable.

(d) Redeterminations. So long as any of the Commitments are in effect and until payment in full of all Loans hereunder, on or around the first Business Day of each May and November (each being a “Scheduled Redetermination Date”), the Lenders shall redetermine the amount of the Borrowing Base and the Monthly Reduction Amount in accordance with Section 2.08(b).

(e) Unscheduled Redeterminations. In addition to the redeterminations of the Borrowing Base and the Monthly Reduction Amount described in Section 2.08(d), (i) Borrower may initiate a redetermination of the Borrowing Base and/or the Monthly Reduction Amount at any other time as it so elects by specifying in writing to Agent (who will promptly notify the Lenders) the date by which Borrower will furnish to Agent and the Lenders a Reserve Report in accordance with Section 8.07(b) and the date by which such redetermination is requested to occur; provided, however, that Borrower may initiate such unscheduled redetermination (x) once per fiscal year and (y) from time to time, pursuant to an acquisition of additional Oil and Gas

Properties by the Borrower or any of its Subsidiaries, and (ii) the Majority Lenders or Agent may initiate a redetermination of the Borrowing Base and/or the Monthly Reduction Amount at any other time they so elect by specifying in writing to Borrower the date by which Borrower is to furnish a Reserve Report in accordance with Section 8.07(b) and the date on which such redetermination is to occur.

(f) Redetermination Concurrent with Transfer. To the extent allowed by Section 9.13, if Borrower Transfers any Property between Scheduled Redetermination Dates with an aggregate fair market value in excess of $500,000, the Borrowing Base shall automatically be reduced upon execution of such Transfer by an amount equal to the Borrowing Base values (as determined by the Majority Lenders in their reasonable discretion) attributed in the immediately preceding determination of the Borrowing Base to the Property which is the subject of such Transfer.

(g) Redetermination Concurrent with Triggering Event. Effective immediately upon the occurrence of a Triggering Event, the Borrowing Base shall automatically be reduced on the date such Triggering Event is effected by an amount equal to the value, if any, assigned to the hedge position or Hedging Agreement under the then effective Borrowing Base, as reasonably determined by Agent.

(h) Effective Upon Notice. Promptly following any redetermination of the Borrowing Base, Agent shall notify in writing Borrower and the Lenders of the new Borrowing Base and/or Monthly Reduction Amount. Any such redetermination of the Borrowing Base and/or Monthly Reduction Amount shall not be effective until Borrower receives written notice thereof.

Section 2.09 Assumption of Risks

. Borrower assumes all risks of the acts or omissions of any beneficiary of any Letter of Credit or any transferee thereof with respect to its use of such Letter of Credit. Neither Issuing Bank (except in the case of gross negligence or willful misconduct on the part of Issuing Bank or any of its employees), its correspondents nor any Lender shall be responsible for the validity, sufficiency or genuineness of certificates or other documents or any endorsements thereon, even if such certificates or other documents should in fact prove to be invalid, insufficient, fraudulent or forged; for errors, omissions, interruptions or delays in transmissions or delivery of any messages by mail, telex, or otherwise, whether or not they be in code; for errors in translation or for errors in interpretation of technical terms; the validity or sufficiency of any instrument transferring or assigning or purporting to transfer or assign any Letter of Credit or the rights or benefits thereunder or proceeds thereof, in whole or in part, which may prove to be invalid or ineffective for any reason; the failure of any beneficiary or any transferee of any Letter of Credit to comply fully with conditions required in order to draw upon any Letter of Credit; or for any other consequences arising from causes beyond Issuing Bank’s control or the control of Issuing Bank’s correspondents. In addition, neither Issuing Bank, Agent nor any Lender shall be responsible for any error, neglect, or default of any of Issuing Bank’s correspondents; and none of the above shall affect, impair or prevent the vesting of any of Issuing Bank’s, Agent’s or any Lender’s rights or powers hereunder or under the Letter of Credit Agreements, all of which rights shall be cumulative. Issuing Bank and its correspondents may accept certificates or other documents that appear on their face to be in order, without responsibility for further investigation of any matter contained therein regardless of any notice or information to the contrary. In furtherance and not in limitation of the foregoing provisions, Borrower agrees that any action, inaction or omission taken or not taken by Issuing Bank or by any correspondent for Issuing Bank in good faith in connection with any Letter of Credit, or any related drafts, certificates, documents or instruments, shall be binding on Borrower and shall not put Issuing Bank or its correspondents under any resulting liability to Borrower.

Section 2.10 Obligation to Reimburse and to Prepay.

(a) Reimbursement Obligations. If a disbursement by Issuing Bank is made under any Letter of Credit, Borrower shall pay to Agent within two (2) Business Days after notice of any such disbursement is received by Borrower, the amount of each such disbursement made by Issuing Bank under the Letter of Credit (if such payment is not sooner effected as may be required under this Section 2.10 or under other provisions of the Letter of Credit), 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 Base Rate Loans through the second Business Day after notice of such disbursement is received by Borrower and (ii) thereafter, the Post Default Rate for Base Rate Loans (but in no event to exceed the Highest Lawful Rate) for the period from and including the third Business Day following the date of such disbursement to and including the date of repayment in full of such disbursed amount. The obligations of Borrower under this Agreement with respect to each Letter of Credit shall be absolute, unconditional and irrevocable and shall be paid or performed strictly in accordance with the terms of this Agreement under all circumstances whatsoever, including, without limitation, but only to the fullest extent permitted by applicable law, the following circumstances: (i) any lack of validity or enforceability of this Agreement, any Letter of Credit or any of the Security Instruments; (ii) any amendment or waiver of (including any default), or any consent to departure from this Agreement (except to the extent permitted by any amendment or waiver), any Letter of Credit or any of the Security Instruments; (iii) the existence of any claim, set-off, defense or other rights which Borrower may have at any time against the beneficiary of any Letter of Credit or any transferee of any Letter of Credit (or any Persons for whom any such beneficiary or any such transferee may be acting), Issuing Bank, Agent, any Lender or any other Person, whether in connection with this Agreement, any Letter of Credit, the Security Instruments, the transactions contemplated hereby or any unrelated transaction; (iv) any statement, certificate, draft, notice or any other document presented under any Letter of Credit proves to have been forged, fraudulent, insufficient or invalid in any respect or any statement therein proves to have been untrue or inaccurate in any respect whatsoever; (v) payment by Issuing Bank under any Letter of Credit against presentation of a draft or certificate which appears on its face to comply, but does not comply, with the terms of such Letter of Credit; (vi) any affiliation between Issuing Bank and any Lender, and (vii) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing. Notwithstanding anything in this Agreement to the contrary, Borrower will not be liable for payment or performance that results from the gross negligence or willful misconduct of Issuing Bank, except where Borrower or any Subsidiary actually recovers the proceeds for itself or Issuing Bank of any payment made by Issuing Bank in connection with such gross negligence or willful misconduct.

(b) Cash Collateral for LC Exposure. In the event of the occurrence of any Event of Default, a payment or prepayment pursuant to Section 2.07(b) or the maturity of the Notes, whether by acceleration or otherwise, an amount equal to 105% of the LC Exposure (or the excess in the case of Section 2.07(b)) shall be deemed to be forthwith due and owing by Borrower to Issuing Bank, Agent and the Lenders as of the date of any such occurrence; Borrower shall prepay the fees payable under Section 2.04(b) with respect to such issued and outstanding Letters of Credit for the full remaining terms of such Letters of Credit; and Borrower’s obligation to pay such amounts 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 Borrower may now or hereafter have against any such beneficiary, Issuing Bank, Agent, the Lenders or any other Person for any reason whatsoever.

Such payments shall be held by Issuing Bank on behalf of the Lenders as cash collateral securing the LC Exposure in an account or accounts at the Principal Office; and Borrower hereby grants to and by its deposit with Agent grants to Agent a security interest in such cash collateral. In the event of any such payment by Borrower of amounts contingently owing under outstanding Letters of Credit and in the event that thereafter drafts or other demands for payment complying with the terms of such Letters of Credit are not made prior to the respective expiration dates thereof, Agent agrees, if no Event of Default has occurred and is continuing or if no other amounts are outstanding under this Agreement, the Notes or any other Loan Documents, to remit to Borrower amounts for which the contingent obligations evidenced by the Letters of Credit have ceased.

(c) Lender Reimbursement. Each Lender severally and unconditionally agrees that it shall promptly reimburse Issuing Bank an amount equal to such Lender’s Percentage Share of any disbursement made by Issuing Bank under any Letter of Credit that is not reimbursed according to this Section 2.10.

(d) Automatic Funding as Loan. Notwithstanding anything to the contrary contained herein, if no Default exists or would result therefrom, to the extent Borrower has not reimbursed Issuing Bank for any drawn upon Letter of Credit within two (2) Business Days after notice of such disbursement has been received by Borrower, the amount of such Letter of Credit reimbursement obligation shall automatically be funded by the Lenders as a Loan hereunder and used by the Lenders to pay such Letter of Credit reimbursement obligation. If an Event of Default exists, such Letter of Credit reimbursement obligation shall not be funded as a Loan, but instead shall accrue interest as provided in Section 2.10(a).

Section 2.11 Lending Offices

The Loans of each Type made by each Lender shall be made and maintained at such Lender’s Applicable Lending Office for Loans of such Type.

ARTICLE III.

(b) Generally. Borrower will pay to Agent, for the account of each Lender, the principal payments required by this Section 3.01.

Section 3.02 Interest.

(a) Interest Rates. Borrower will pay to Agent, for the account of each Lender, interest on the unpaid principal amount of each Loan made by such Lender for the period commencing on the date such Loan is made to, but excluding, the date such Loan shall be paid in full, at the following rates per annum:

(i) if such a Loan is a Base Rate Loan or any other Obligation other than a LIBOR Loan, the Base Rate (as in effect from time to time) plus the Applicable Margin, but in no event to exceed the Highest Lawful Rate; and

(ii) if such Loan is a LIBOR Loan, for each Interest Period relating thereto, the LIBOR Adjusted Rate for such Loan plus the Applicable Margin (as in effect from time to time), but in no event to exceed the Highest Lawful Rate.

ARTICLE IV.

PAYMENTS; PRO RATA TREATMENT; COMPUTATIONS; ETC.

Section 4.01 Payments

Except to the extent otherwise provided herein, all payments of principal, interest and other amounts to be made by Borrower under this Agreement, the Notes or any other Loan Document shall be made in Dollars, in immediately available funds, to Agent at such account as Agent shall specify by notice to Borrower from time to time, not later than 11:00 a.m. Houston, Texas time on the date on which such payments shall become due (each such payment made after such time on such due date to be deemed to have been made on the next succeeding Business Day). Such payments shall be made without (to the fullest extent permitted by applicable law) defense, set-off or counterclaim and in connection therewith, Borrower hereby waives (to the fullest extent permitted by applicable law) all defenses, rights of set-off and counterclaims it may have with respect to such payments. Each payment received by Agent under this Agreement or any Note for account of a Lender shall be paid promptly to such Lender in immediately available funds. Except as otherwise provided in the definition of “Interest Period”, if the due date of any payment under this Agreement or any Note would otherwise fall on a day which is not a Business Day such date shall be extended to the next succeeding Business Day and interest shall be payable for any principal so extended for the period of such extension. At the time of each payment to Agent of any principal of or interest on any borrowing, Borrower shall notify Agent of the Loans to which such payment shall apply. In the absence of such notice Agent may specify the Loans to which such payment shall apply, but to the extent possible such payment or prepayment will be applied first to the Loans comprised of Base Rate Loans.

Section 4.02 Pro Rata Treatment

Except to the extent otherwise provided herein each Lender agrees that: (i) each borrowing from the Lenders under Section 2.01 and each continuation and conversion under Section 2.02 shall be made from the Lenders pro rata in accordance with their

Percentage Share, each payment of fees under Section 2.04(a) and Section 2.04(b)(i) shall be made for account of the Lenders pro rata in accordance with their Percentage Share, and each termination or reduction of the amount of the Aggregate Maximum Credit Amounts under Section 2.03(b) shall be applied to the Commitment of each Lender, pro rata according to the amounts of its respective Commitment; (ii) each payment of principal of Loans by Borrower shall be made for account of the Lenders pro rata in accordance with the respective unpaid principal amount of the Loans held by the Lenders; (iii) each payment of interest on Loans by Borrower shall be made for account of the Lenders pro rata in accordance with the amounts of interest due and payable to the respective Lenders; and (iv) each reimbursement by Borrower of disbursements under Letters of Credit shall be made for account of Issuing Bank or, if funded by the Lenders, pro rata for the account of the Lenders, in accordance with the amounts of reimbursement obligations due and payable to each respective Lender.

Section 4.03 Computations Interest on LIBOR Loans and fees shall be computed on the basis of a year of 360 days and actual days elapsed (including the first day but excluding the last day) occurring in the period for which such interest is payable, unless such calculation would exceed the Highest Lawful Rate, in which case interest shall be calculated on the per annum basis of a year of 365 or 366 days, as the case may be. Interest on Base Rate Loans shall be computed on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed (including the first day but excluding the last day) occurring in the period for which such interest is payable.

Section 4.04 Non-receipt of Funds by Agent

(a) Funding by Lenders; Presumption by Agent. Unless Agent shall have received notice from a Lender, prior to the proposed date of any borrowing that such Lender will not make available to Agent such Lender’s share of such borrowing, Agent may assume that such Lender has made such share available on such date and may, in reliance upon such assumption, make available to Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable borrowing available to Agent, then the applicable Lender and Borrower severally agree to pay to Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including the date such amount is made available to Borrower to but excluding the date of payment to Agent, at (i) in the case of a payment to be made by such Lender, the greater of the Federal Funds Rate and a rate determined by Agent in accordance with banking industry rules on interbank compensation, and (ii) in the case of a payment to be made by Borrower, the interest rate applicable to Base Rate Loans. If Borrower and such Lender shall pay such interest to Agent for the same or an overlapping period, Agent shall promptly remit to Borrower the amount of such interest paid by Borrower for such period. If such Lender pays its share of the applicable borrowing to Agent, then the amount so paid shall constitute such Lender’s Loan included in such borrowing. Any payment by Borrower shall be without prejudice to any claim Borrower may have against a Lender that shall have failed to make such payment to Agent.

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

Section 4.05 Set-off, Sharing of Payments, Etc.

(a) If an Event of Default shall have occurred and be continuing, Agent, each Lender, Issuing Bank, and each of their respective Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by applicable law, to set off and apply any and all deposits (general or special, time or demand, provisional or final, in whatever currency) at any time held, and other obligations (in whatever currency) at any time owing, by Agent, such Lender, Issuing Bank or any such Affiliate, to or for the credit or the account of Borrower or any other Loan Party against any and all of the obligations of Borrower or such Loan Party now or hereafter existing under this Agreement or any other Loan Document to Agent, such Lender or Issuing Bank or their respective Affiliates, irrespective of whether or not Agent, such Lender, Issuing Bank or Affiliate shall have made any demand under this Agreement or any other Loan Document and although such obligations of Borrower or such Loan Party may be contingent or unmatured or are owed to a branch, office or Affiliate of Agent, such Lender or Issuing Bank different from the branch, office or Affiliate holding such deposit or obligated on such indebtedness; provided that in the event that any Defaulting Lender shall exercise any such right of setoff, (x) all amounts so set off shall be paid over immediately to Agent for further application in accordance with the provisions of Section 12.07 and, pending such payment, shall be segregated by such Defaulting Lender from its other funds and deemed held in trust for the benefit of Agent, Issuing Bank, and the Lenders, and (y) the Defaulting Lender shall provide promptly to Agent a statement describing in reasonable detail the Obligations owing to such Defaulting Lender as to which it exercised such right of setoff. The rights of Agent, each Lender, Issuing Bank and their respective Affiliates under this Section are in addition to other rights and remedies (including other rights of setoff) that Agent, such Lenders, Issuing Bank or their respective Affiliates may have. Each Lender and Issuing Bank agrees to notify Borrower and Agent promptly after any such setoff and application; provided that the failure to give such notice shall not affect the validity of such setoff and application.

(b) If any Lender shall, by exercising any right of setoff or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans or other obligations hereunder resulting in such Lender receiving payment of a proportion of the aggregate amount of its Loans and accrued interest thereon or other such obligations greater than its pro rata share thereof as provided herein, then the Lender receiving such greater proportion shall (x) notify Agent of such fact, and (y) purchase (for cash at face value) participations in the Loans and such other obligations of the other Lenders, or make such other adjustments as shall be equitable, 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 other amounts owing them; provided that:

(i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest; and

(ii) the provisions of this paragraph shall not be construed to apply to (x) any payment made by Borrower pursuant to and in accordance with the express terms of this Agreement (including the application of funds arising from the existence of a Defaulting Lender), or (y) 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 Letters of Credit to any assignee or participant, other than to the Borrower or any Subsidiary thereof (as to which the provisions of this paragraph shall apply).

Each Loan Party consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against each Loan Party rights of setoff and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of each Loan Party in the amount of such participation. If under any applicable bankruptcy, insolvency or other similar law, any Lender receives a secured claim in lieu of a set-off to which this Section 4.05 applies, such Lender shall, to the extent practicable, exercise its rights in respect of such secured claim in a manner consistent with the rights of the Lenders entitled under this Section 4.05 to share the benefits of any recovery on such secured claim.

Section 4.06 Taxes.

(a) Defined Terms. For purposes of this Section 4.06, the term “Lender” includes Issuing Bank and the term “applicable law” includes FATCA.

(b) Payments Free and Clear. Any and all payments by or on account of any obligation of any Loan Party under any Loan Document shall be made without deduction or withholding for any Taxes, except as required by applicable law. If any applicable law (as determined in the good faith discretion of an applicable Withholding Agent) requires the deduction or withholding of any Tax from any such payment by a Withholding Agent, then the applicable Withholding Agent shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with applicable law and, if such Tax is an Indemnified Tax, then the sum payable by the applicable Loan Party shall be increased as necessary so that after such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums payable under this Section) the applicable Recipient receives an amount equal to the sum it would have received had no such deduction or withholding been made.

(c) Other Taxes. The Loan Parties shall timely pay to the relevant Governmental Authority in accordance with applicable law, or at the option of Agent timely reimburse it for the payment of, any Other Taxes.

(d) INDEMNIFICATION BY LOAN PARTIES. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE LOAN PARTIES SHALL JOINTLY AND SEVERALLY INDEMNIFY EACH RECIPIENT, WITHIN 10 DAYS AFTER DEMAND THEREFOR, FOR THE FULL AMOUNT OF ANY INDEMNIFIED TAXES (INCLUDING INDEMNIFIED TAXES IMPOSED OR ASSERTED ON OR ATTRIBUTABLE TO AMOUNTS PAYABLE UNDER THIS SECTION) PAYABLE OR PAID BY SUCH RECIPIENT OR REQUIRED TO BE WITHHELD OR DEDUCTED FROM A PAYMENT TO SUCH RECIPIENT AND ANY REASONABLE EXPENSES ARISING THEREFROM OR WITH RESPECT THERETO, WHETHER OR NOT SUCH INDEMNIFIED TAXES WERE CORRECTLY OR LEGALLY IMPOSED OR ASSERTED BY THE RELEVANT GOVERNMENTAL AUTHORITY. A CERTIFICATE AS TO THE AMOUNT OF SUCH PAYMENT OR LIABILITY DELIVERED TO BORROWER BY A LENDER (WITH A COPY TO AGENT), OR BY AGENT ON ITS OWN BEHALF OR ON BEHALF OF A LENDER, SHALL BE CONCLUSIVE ABSENT MANIFEST ERROR.

(e) INDEMNIFICATION BY THE LENDERS. EACH LENDER SHALL SEVERALLY INDEMNIFY AGENT, WITHIN 10 DAYS AFTER DEMAND THEREFOR, FOR (I) ANY INDEMNIFIED TAXES ATTRIBUTABLE TO SUCH LENDER (BUT ONLY TO THE EXTENT THAT ANY LOAN PARTY HAS NOT ALREADY INDEMNIFIED AGENT FOR SUCH INDEMNIFIED TAXES AND WITHOUT LIMITING THE

OBLIGATION OF THE LOAN PARTIES TO DO SO), (II) ANY TAXES ATTRIBUTABLE TO SUCH LENDER’S FAILURE TO COMPLY WITH THE PROVISIONS OF SECTION 12.06 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 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 AGENT SHALL BE CONCLUSIVE ABSENT MANIFEST ERROR. EACH LENDER HEREBY AUTHORIZES 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 AGENT TO THE LENDER FROM ANY OTHER SOURCE AGAINST ANY AMOUNT DUE TO AGENT UNDER THIS SECTION 4.06(E).

(f) Evidence of Payments. As soon as practicable after any payment of Taxes by any Loan Party to a Governmental Authority pursuant to this Section 4.06, such Loan Party shall deliver to 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 Agent.

(g) Status of Lenders.

(i) Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Loan Document shall deliver to Borrower and Agent, at the time or times reasonably requested by Borrower or Agent, such properly completed and executed documentation reasonably requested by Borrower or Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably requested by Borrower or Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by Borrower or Agent as will enable Borrower or 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 4.06(g)(ii)(1), (ii)(2) and (ii)(4) 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,

(1) any Lender that is a U.S. Person shall deliver to Borrower and 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 Agent), executed originals of IRS Form W-9 certifying that such Lender is exempt from U.S. federal backup withholding tax;

(2) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to Borrower and 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 Borrower or Agent), whichever of the following is applicable:

(a) 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;

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

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

(d) to the extent a Foreign Lender is not the beneficial owner, executed originals of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN, a U.S. Tax Compliance Certificate substantially in the form of Exhibit H-2 or Exhibit H-3, IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Lender is a partnership and one or more direct or indirect partners of such Foreign Lender are claiming the portfolio interest exemption, such Foreign Lender may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit H-4 on behalf of each such direct and indirect partner;

(3) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to Borrower and 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 Borrower or Agent), executed originals of any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in U.S. federal withholding Tax, duly completed, together with such supplementary documentation as may be prescribed by applicable law to permit Borrower or Agent to determine the withholding or deduction required to be made; and

(4) 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 Borrower and Agent at the time or times prescribed by law and at such time or times reasonably requested by Borrower or 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 Borrower or Agent as may be necessary for Borrower and 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 (4), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

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 Agent in writing of its legal inability to do so.

(h) Treatment of Certain Refunds. If any party determines, in its sole discretion exercised in good faith, that it has received a refund of any Taxes as to which it has been indemnified pursuant to this Section 4.06 (including by the payment of additional amounts pursuant to this Section 4.06), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section 4.06 with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such indemnified party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over pursuant to this Section 4.06(h) (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event that such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this Section 4.06(h), in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this Section 4.06(h) the payment of which would place the indemnified party in a less favorable net after-Tax position than the indemnified party would have been in if the Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax had never been paid.

ARTICLE V.

CAPITAL ADEQUACY AND ADDITIONAL COSTS

Section 5.01 Additional Costs.

(a) LIBOR Regulations, etc. If any Regulatory Change shall:

(i) impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement against assets of, deposits with

or for the account of, or credit extended or participated in by, any Lender (except any reserve requirement reflected in the LIBOR Adjusted Rate) or Issuing Bank;

(ii) subject any Recipient to any Taxes (other than (A) Indemnified Taxes, (B) Taxes described in clauses (b) through (d) of the definition of Excluded Taxes and (C) Connection Income Taxes) on its Loans, loan principal, letters of credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto; or

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

and the result of any of the foregoing shall be to increase the cost to such Lender or such other Recipient of making, converting to, continuing or maintaining any Loan or of maintaining its obligation to make any such Loan, or to increase the cost to such Lender, Issuing Bank or such other Recipient of participating in, issuing or maintaining any Letter of Credit (or of maintaining its obligation to participate in or to issue any Letter of Credit), or to reduce the amount of any sum received or receivable by such Lender, Issuing Bank or other Recipient hereunder (whether of principal, interest or any other amount) then, upon request of such Lender, Issuing Bank or other Recipient, Borrower will pay to such Lender, Issuing Bank or other Recipient, as the case may be, such additional amount or amounts as will compensate such Lender, Issuing Bank or other Recipient, as the case may be, for such additional costs incurred or reduction suffered. If any Lender requests compensation from Borrower under this Section 5.01(a), Borrower may, by notice to such Lender, suspend the obligation of such Lender to make additional Loans of the Type with respect to which such compensation is requested until the Regulatory Change giving rise to such request ceases to be in effect (in which case the provisions of Section 5.04 shall be applicable).

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

(c) Certificates for Reimbursement. A certificate of a Lender or Issuing Bank setting forth the amount or amounts necessary to compensate such Lender or Issuing Bank or its holding company, as the case may be, as specified in Section 5.01(a) or (b) and delivered to Borrower, shall be conclusive absent manifest error. Borrower shall pay such Lender or Issuing Bank, as the case may be, the amount shown as due on any such certificate within 10 days after receipt thereof.

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

Section 5.02 Limitation on LIBOR Loans Anything herein to the contrary notwithstanding, if, on or prior to the determination of any LIBOR Adjusted Rate for any Interest Period:

(a) Agent determines (which determination shall be conclusive, absent manifest error) that quotations of interest rates for the relevant deposits referred to in the definition of “LIBOR Adjusted Rate” in Section 1.02 are not being provided in the relevant amounts or for the relevant maturities for purposes of determining rates of interest for LIBOR Loans as provided herein; or

(b) Agent determines (which determination shall be conclusive, absent manifest error) that the relevant rates of interest referred to in the definition of “LIBOR Adjusted Rate” in Section 1.02 upon the basis of which the rate of interest for LIBOR Loans for such Interest Period is to be determined are not sufficient to adequately cover the cost to the Lenders of making or maintaining LIBOR Loans;

then Agent shall give Borrower prompt notice thereof, and so long as such condition remains in effect, the Lenders shall be under no obligation to make additional LIBOR Loans.

Section 5.03 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 LIBOR Loans hereunder, then such Lender shall promptly notify Borrower thereof and such Lender’s obligation to make LIBOR Loans shall be suspended until such time as such Lender may again make and maintain LIBOR Loans (in which case the provisions of Section 5.04 shall be applicable).

Section 5.04 Base Rate Loans Pursuant to Sections 5.01, 5.02 and 5.03 If the obligation of any Lender to make LIBOR Loans shall be suspended pursuant to Sections 5.01, 5.02 or 5.03 (“Affected Loans”), all Affected Loans which would otherwise be made by such Lender shall be made instead as Base Rate Loans (and, if an event referred to in Section 5.01(a) or Section 5.03 has occurred and such Lender so requests by notice to Borrower, all Affected Loans of such Lender then outstanding shall be automatically converted into Base Rate 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) Base Rate Loans, all payments of principal which would otherwise be applied to such Lender’s Affected Loans shall be applied instead to its Base Rate Loans.

Section 5.05 Compensation Borrower shall pay to each Lender within thirty (30) days of receipt of written request of such Lender (which request shall set forth, in reasonable detail, the basis for requesting such amounts and which shall be conclusive and binding for all purposes provided that such determinations are made on a reasonable basis), such amount or amounts as shall compensate it for any loss, cost, expense or liability which such Lender determines are attributable to:

(a) any payment, prepayment or conversion of a LIBOR Loan properly made by such Lender or Borrower for any reason (including, without limitation, the acceleration of the

Loans pursuant to Section 10.01) on a date other than the last day of the Interest Period for such Loan; or

(b) any failure by Borrower for any reason (including but not limited to, the failure of any of the conditions precedent specified in Article VI to be satisfied) to borrow, continue or convert a LIBOR Loan from such Lender on the date for such borrowing, continuation or conversion specified in the relevant notice given pursuant to Section 2.02(c). Without limiting the effect of the preceding sentence, such compensation shall include an amount equal to the excess, if any, of (i) the amount of interest which would have accrued on the principal amount so paid, prepaid or converted or not borrowed for the period from the date of such payment, prepayment or conversion or failure to borrow to the last day of the Interest Period for such Loan (or, in the case of a failure to borrow, the Interest Period for such Loan which would have commenced on the date specified for such borrowing) at the applicable rate of interest for such Loan provided for herein over (ii) the interest component of the amount such Lender would have bid in the London interbank market for Dollar deposits of leading banks in amounts comparable to such principal amount and with maturities comparable to such period (as reasonably determined by such Lender).

Section 5.06 Mitigation Obligations; Replacement of Lenders

(a) Designation of a Different Lending Office. If any Lender requests compensation under Section 5.01, or requires Borrower to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 4.06, then such Lender shall (at the request of Borrower) use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 5.01 or Section 4.06, as the case may be, in the future, and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b) Replacement of Lenders. If any Lender requests compensation under Section 5.01, or requires Borrower to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 4.06, and, in each case, such Lender has declined or is unable to designate a different lending office in accordance with Section 5.06(a), or if any Lender is a Defaulting Lender, then Borrower may, at its sole expense and effort, upon notice to such Lender and Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in, and consents required by, Section 12.06), all of its interests, rights (other than its existing rights to payments pursuant to Section 5.01 or Section 4.06) and obligations under this Agreement and the related Loan Documents to an Eligible Assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that:

(i) Borrower shall have paid to Agent the assignment fee (if any) specified in Section 12.06;

(ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and participations in disbursements under Letters of Credit that have not yet been reimbursed, accrued interest thereon, accrued fees and all other amounts payable to it hereunder and under the other Loan Documents (including any amounts under Section 5.05) 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);

(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 4.06, such assignment will result in a reduction in such compensation or payments thereafter; and

(iv) such assignment does not conflict with applicable Governmental Requirements.

A Lender shall not be required to make any such assignment or delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances entitling Borrower to require such assignment and delegation cease to apply.

REPRESENTATIONS AND WARRANTIES

Borrower represents and warrants to Agent and the Lenders that (each representation and warranty herein is given as of the Closing Date and shall be deemed repeated and reaffirmed on the dates of each borrowing and issuance, renewal, extension or reissuance of a Letter of Credit as provided in Section 6.02):

Section 7.04 No Breach Neither the execution and delivery of the Loan Documents, nor compliance with the terms and provisions thereof, will conflict with or result in a breach of, or require any consent which has not been obtained as of the Closing Date under, the respective Charter Documents of Borrower or any Subsidiary, or any Governmental Requirement or any agreement or instrument to which Borrower or any Subsidiary is a party or by which it is bound or to which it or its Properties are subject, or constitute a default under any such agreement or instrument, or result in the creation or imposition of any Lien upon any of the revenues or assets of Borrower or any Subsidiary pursuant to the terms of any such agreement or instrument other than the Liens created by the Loan Documents.

Section 7.05 Authority Borrower and each Subsidiary have all necessary entity power and authority to execute, deliver and perform its obligations under the Loan Documents to which it is a party; and the execution, delivery and performance by Borrower and each Subsidiary of the Loan Documents to which it is a party, have been duly authorized by all necessary entity action on its part; and the Loan Documents constitute the legal, valid and binding obligations of Borrower and each Subsidiary party thereto, enforceable in accordance with their terms.

(d) No Plan (other than a defined contribution plan) or any trust created under any such Plan has been terminated since September 2, 1974.

Section 7.15 Defaults Neither Borrower nor any Subsidiary is in default nor has any event or circumstance occurred which, but for the expiration of any applicable grace period or the giving of notice, or both, would constitute a default under any material agreement or instrument to which Borrower or any Subsidiary is a party or by which Borrower or any Subsidiary is bound which default would have a Material Adverse Effect. No Default hereunder has occurred and is continuing.

Section 7.16 Environmental Matters Except (i) as provided in Schedule 7.16 or (ii) as would not have a Material Adverse Effect (or with respect to (c), (d) and (e) below, where the failure to take such actions would not have a Material Adverse Effect):

(e) Borrower has taken all steps reasonably necessary to determine, and has determined, that no hazardous substances, solid waste, or oil and gas exploration and production wastes, have been disposed of or otherwise released and there has been no threatened release of any hazardous substances on or to any Property of Borrower or any Subsidiary except in compliance with Environmental Laws and so as not to pose an imminent and substantial endangerment to public health or welfare or the environment;

(f) To the extent applicable, all Property of Borrower and each Subsidiary currently satisfies all design, operation, and equipment requirements imposed by the OPA or scheduled as of the Closing Date to be imposed by the OPA during the term of this Agreement, and Borrower does not have any reason to believe that such Property, to the extent subject to OPA, will not be able to maintain compliance with the OPA requirements during the term of this Agreement; and

(g) Neither Borrower nor any Subsidiary has any known contingent liability in connection with any release or threatened release of any oil, hazardous substance or solid waste into the environment.

Section 7.17 Compliance with the Law

. Neither Borrower nor any Subsidiary has violated any Governmental Requirement or failed to obtain any license, permit, franchise or other governmental authorization necessary for the ownership of any of its Properties or the conduct of its business, which violation or failure would have (in the event such violation or failure were asserted by any Person through appropriate action) a Material Adverse Effect. Except for such acts or failures to act as would not have a Material Adverse Effect, the Oil and Gas Properties (and properties unitized therewith) have been maintained, operated and developed in a good and workmanlike manner and in conformity with all applicable laws and all rules, regulations and orders of all duly constituted authorities having jurisdiction and in conformity with the provisions of all leases, subleases or other contracts comprising a part of the Hydrocarbon Interests and other contracts and agreements forming a part of the Oil and Gas Properties; specifically in this connection, (i) after the Closing Date, no Oil and Gas Property is subject to having allowable production reduced below the full and regular allowable (including the maximum permissible tolerance) because of any overproduction (whether or not the same was permissible at the time) prior to the Closing Date and (ii) none of the xxxxx comprising a part of the Oil and Gas Properties (or properties unitized therewith) are deviated more than the maximum permitted by applicable laws, regulations, rules and orders, and such xxxxx are, in fact, bottomed under and are producing from, and the well bores are wholly within, the Oil and Gas Properties (or in the case of xxxxx located on properties unitized therewith, such unitized properties).

Section 7.21 Material Agreements. Set forth on Schedule 7.21 hereto is a complete and correct list of all material agreements, leases (other than Hydrocarbon Interests), indentures, purchase agreements, letters of credit, guarantees, joint venture agreements and other agreements and contracts in effect or to be in effect on the Closing Date (other than Hedging Agreements) providing for, evidencing, securing or otherwise relating to any Debt of Borrower or any of its Subsidiaries, and all obligations of Borrower or any of its Subsidiaries to issuers of surety or appeal bonds issued for account of Borrower or any such Subsidiary.

Section 7.22 Solvency. Immediately upon the Closing Date, the Borrower and its Subsidiaries are Solvent.

Section 7.23 Gas Imbalances. Except as set forth on Schedule 7.23 or on the most recently delivered Reserve Report Certificate, on a net basis there are no gas imbalances, take or pay or other prepayments with respect to Borrower’s or any Subsidiary’s Oil and Gas Properties which would require Borrower or a Subsidiary to deliver, in the aggregate, two percent (2%) or more of the monthly production from Hydrocarbons produced from Borrower’s or such Subsidiary’s Oil and Gas Properties at some future time without then or thereafter receiving full payment therefor.

Section 7.24 Improved Real Estate. There is no “Building” (as defined in the applicable Flood Insurance Regulation) or Manufactured (Mobile) Home (as defined in the applicable Flood Insurance Regulation) located on the lands covered by the Mortgaged Property that are critical to the operations of any Mortgaged Property for the exploration and production of oil and gas.

Neither Borrower nor any of its Subsidiaries (a) is a Sanctioned Person or a Sanctioned Entity, (b) has its assets located in Sanctioned Entities, or (c) derives revenues from investments in, or transactions with Sanctioned Persons or Sanctioned Entities. No proceeds of any Loan will be used to fund any operations in, finance any investments or activities in, or make any

Neither Borrower nor any of its Subsidiaries or, to their knowledge, any of their Related Parties (a) is an “enemy” or an “ally of the enemy” within the meaning of Section 2 of the Trading with the Enemy Act of the United States (50 U.S.C. App. §§ 1 et seq.), (b) is in violation of (i) the Trading with the Enemy Act, (ii) any of the foreign assets control regulations of the United States Treasury Department (31 CFR, Subtitle B, Chapter V) or any enabling legislation or executive order relating thereto or (iii) the PATRIOT Act (collectively, the “Anti-Terrorism Laws”) or (c) is a Sanctioned Person. No part of the proceeds of any Loan or Letter of Credit hereunder will be unlawfully used directly or indirectly to fund any operations in, finance any investments or activities in or make any payments to, a Sanctioned Person or a Sanctioned Country, or in any other manner that will result in any violation by any Person (including any Lender, the Agent or the Issuing Bank) of any Anti-Terrorism Laws, or for any payments to any governmental official or employee, political party, official of a political party, candidate for political office, or anyone else acting in an official capacity, in order to obtain, retain or direct business or obtain any improper advantage, in violation of the United States Foreign Corrupt Practices Act of 1977, as amended and in effect from time to time.

(c) the purpose of any Swap Agreements in respect of any commodity entered into or executed in connection with this Agreement is to hedge commodity price risks incidental to the Borrower’s and its Subsidiaries’ business and arising from potential changes in the price of such commodity; and

(d) each Swap Agreement entered into or executed in connection with this Agreement mitigates against the risk of repayment hereof and is not for the purpose of speculation.

For purposes of this Section 7.26, the term (i) “financial term” shall include, without limitation, the duration or term of this Agreement, rate of interest, the currency or currencies in which the Loan is made and its principal amount, and (ii) “transfer of principal” means any draw of principal under this Agreement, and any amendment, restructuring, extension or other modification of this Agreement.

Section 8.02 Litigation Borrower shall promptly give to Agent notice of: (i) all legal or arbitral proceedings, and of all proceedings before any Governmental Authority affecting Borrower or any Subsidiary, except proceedings which, if adversely determined, would not have a Material Adverse Effect, and (ii) of any litigation or proceeding against or adversely affecting Borrower or any Subsidiary in which the amount involved is not covered in full by insurance (subject to normal and customary deductibles and for which the insurer has not assumed the defense), or in which injunctive or similar relief is sought.

Section 8.03 Maintenance, Etc.

(a) Generally. Borrower shall and shall cause each Subsidiary to: preserve and maintain its corporate existence and all of its material rights, privileges, licenses, franchises and other rights necessary to conduct its business; keep books of record and account in which full, true and correct entries will be made of all dealings or transactions in relation to its business and activities; comply with all Governmental Requirements if failure to comply with such requirements will have a Material Adverse Effect; pay and discharge all taxes, assessments and governmental charges or levies imposed on it or on its income or profits or on any of its Property prior to the date on which penalties attach thereto, except for any such tax, assessment, charge or levy the payment of which is being contested in good faith and by proper proceedings and against which adequate reserves are being maintained; upon reasonable notice, permit representatives of Agent or any Lender, during normal business hours, to examine, copy and make extracts from its books and records, to inspect its Properties, and to discuss its business and affairs with its officers, all to the extent reasonably requested by such Lender or Agent (as the case may be).

(b) Insurance. Borrower shall and shall cause each Subsidiary to keep, or cause to be kept, insured by financially sound and reputable insurers (having a minimum A.M. Best rating of A, size category VII) all Property of a character usually insured by Persons engaged in the same or similar business similarly situated against loss or damage of the kinds and in the amounts customarily insured against by such Persons and carry such other insurance as is usually carried by such Persons including, without limitation, environmental risk insurance to the extent reasonably available, or as Agent may reasonably request. Borrower shall promptly obtain endorsements to such insurance policies naming “BOKF, NA dba Bank of Texas, as Agent for the Beneficiaries” as an additional insured, assignee and loss payee (which shall include, as applicable, identification as mortgagee), as applicable, on each insurance policy required to be maintained pursuant to this Section 8.03(b) and containing provisions that such policies will not be canceled without 30 days prior written notice having been given by the insurance company to Agent. Borrower will not, and will not permit any Subsidiary to, bring or keep any article on any business location of any Loan Party, or cause or allow any condition to exist, if the presence of such article or the occurrence of such condition could reasonably cause the invalidation of any insurance required by this Section 8.03(b), or would otherwise be prohibited by the terms thereof. In the event Borrower fails to provide Agent with evidence of the insurance coverage required by this Agreement, Agent may purchase insurance at Borrower’s expense to protect Agent’s interests in the Collateral. This insurance may, but need not, protect Borrower’s interests. The coverage

purchased by Agent may not pay any claim made by Borrower or any claim that is made against Borrower in connection with the Collateral. Borrower may later cancel any insurance purchased by Agent, but only after providing Agent with evidence that Borrower has obtained insurance as required by this Agreement. If Agent purchases insurance for the Collateral, to the fullest extent provided by law Borrower will be responsible for the costs of that insurance, including interest and other charges imposed by Agent in connection with the placement of the insurance, until the effective date of the cancellation or expiration of the insurance. The costs of the insurance may be added to the Obligations. The costs of the insurance may be more than the cost of insurance Borrower is able to obtain on its own.

(c) Proof of Insurance. Contemporaneously with the delivery of the financial statements required by Section 8.01(a) to be delivered for each year, Borrower will furnish or cause to be furnished to Agent and the Lenders a certificate of insurance coverage from the insurer in form and substance satisfactory to Agent and, if requested, will furnish Agent and the Lenders copies of the applicable policies.

(d) Oil and Gas Properties. Borrower will and will cause each Subsidiary to, at its own expense, do or cause to be done all things reasonably necessary to preserve and keep in good repair, working order and efficiency all of its Oil and Gas Properties and other material Properties including, without limitation, all equipment, machinery and facilities, and from time to time will make all the reasonably necessary repairs, renewals and replacements so that at all times the state and condition of its Oil and Gas Properties and other material Properties will be fully preserved and maintained, except to the extent a portion of such Properties is no longer capable of economically producing Hydrocarbons. Borrower will and will cause each Subsidiary to promptly: (i) pay and discharge, or make reasonable and customary efforts to cause to be paid and discharged, all delay rentals, royalties, expenses and indebtedness accruing under the leases or other agreements affecting or pertaining to its Oil and Gas Properties, (ii) perform or make reasonable and customary efforts to cause to be performed, in accordance with industry standards, the obligations required by each and all of the assignments, deeds, leases, subleases, contracts and agreements affecting its interests in its Oil and Gas Properties and other material Properties, and (iii) do all other things necessary to keep unimpaired, except for Liens described in Section 9.02, its rights with respect to its Oil and Gas Properties and other material Properties and prevent any forfeiture thereof or a default thereunder, except to the extent a portion of such Properties is no longer capable of producing Hydrocarbons in economically reasonable amounts and except for dispositions not prohibited by Section 9.13. Borrower will and will cause each Subsidiary to operate its Oil and Gas Properties and other material Properties or cause or make reasonable and customary efforts to cause such Oil and Gas Properties and other material Properties to be operated in the manner of a prudent operator in accordance with the practices of the industry and in compliance with all applicable contracts and agreements and in compliance in all material respects with all Governmental Requirements. Borrower shall, and shall cause each Subsidiary to, subordinate in favor of Agent for the benefit of the Lenders any contractual or statutory Liens held by the Borrower or such Subsidiary as co-working interest owner under joint operating agreements or similar contractual arrangements with respect to the Borrower’s or such Subsidiary’s share of the expense of exploration, development and operation of oil, gas and mineral leasehold or fee interests jointly owned with others and operated by the Borrower or any Subsidiary.

Section 8.04 Environmental Matters.

(a) Establishment of Procedures. Borrower will and will cause each Subsidiary to establish and implement such procedures as may be reasonably necessary to continuously

determine and assure that any failure of the following does not have a Material Adverse Effect: (i) all Property of Borrower and its Subsidiaries and the operations conducted thereon and other activities of Borrower and its Subsidiaries are in compliance with and materially do not violate the requirements of any Environmental Laws, (ii) no oil, hazardous substances or solid wastes are disposed of or otherwise released on or to any Property owned by any such party except in compliance with Environmental Laws, (iii) no hazardous substance will be released on or to any such Property in a quantity equal to or exceeding that quantity which requires reporting pursuant to Section 103 of CERCLA, and (iv) no oil, oil and gas exploration and production wastes or hazardous substance is released on or to any such Property so as to pose an imminent and substantial endangerment to public health or welfare or the environment.

(b) Notice of Action. Borrower will promptly notify Agent and the Lenders in writing of any threatened action, investigation or inquiry by any Governmental Authority of which Borrower has knowledge in connection with any Environmental Laws, excluding routine testing and corrective action.

(c) Future Acquisitions. Borrower will and will cause each Subsidiary to provide environmental audits and tests as reasonably requested by Agent and the Lenders (or as otherwise required to be obtained by Agent or the Lenders by any Governmental Authority) in connection with any future acquisitions of Oil and Gas Properties or other material Properties.

Section 8.05 Further Assurances Borrower will and will cause each Subsidiary to cure promptly any defects in the creation and issuance of the Notes and the execution and delivery of this Agreement and any other Loan Document. Borrower, at its expense, will and will cause each Subsidiary to promptly execute and deliver to Agent upon request all such other documents, agreements and instruments to comply with or accomplish the covenants and agreements of Borrower or any Subsidiary, as the case may be, in this Agreement and any other Loan Document, or to further evidence and more fully describe the Collateral intended as security for the Obligations or to correct any omissions in the Loan Documents, or to state more fully the security obligations set out herein or in any of the Loan Documents, or to perfect, protect or preserve any Liens created pursuant to any of the Security Instruments, or to make any recordings, to file any notices or obtain any consents, all as may be necessary or appropriate in connection therewith.

Section 8.06 Performance of Obligations Borrower will pay the Notes according to the reading, tenor and effect thereof; and Borrower will and will cause each Subsidiary to do and perform every act and discharge all of the obligations to be performed and discharged by them under the Loan Documents, at the time or times and in the manner specified.

Section 8.07 Engineering Reports.

(a) Scheduled Redetermination. Not less than 30 days prior to each Scheduled Redetermination Date, Borrower shall furnish to Agent and the Lenders a Reserve Report. The March 1 Reserve Report of each year shall be prepared by certified independent petroleum engineers or other independent petroleum consultant(s) reasonably acceptable to Agent and the September 1 Reserve Report of each year shall be prepared by or under the supervision of the chief engineer of Borrower who shall certify such Reserve Report to be true and accurate and to have been prepared in accordance with the procedures used in the immediately preceding March 1 Reserve Report.

(b) Unscheduled Redetermination. In the event of an unscheduled redetermination, Borrower shall furnish to Agent and the Lenders a Reserve Report prepared by or under the supervision of the chief engineer of Borrower who shall certify such Reserve Report to be true

and accurate and to have been prepared in accordance with the procedures used in the immediately preceding Reserve Report. For any unscheduled redetermination requested by the Majority Lenders, Agent or Borrower pursuant to Section 2.08(e)), Borrower shall provide as soon as possible, but in any event no later than 30 days following the receipt of the request by Agent, such Reserve Report with an “as of” date not more than 60 days prior to the anticipated date of redetermination or as otherwise required by the Majority Lenders or Agent.

Section 8.08 Title Information Delivery On or before the delivery to Agent and the Lenders of each Reserve Report required by Section 8.07(a), Borrower will deliver title information in form and substance reasonably acceptable to Agent covering enough of the Mortgaged Properties evaluated by such Reserve Report that were not included in the immediately preceding Reserve Report, so that Agent shall have received together with title information previously delivered to Agent, satisfactory title information on at least (80%) of the value of the Oil and Gas Properties evaluated in the most recent Reserve Report that are Proven Reserves).

(a) Cure of Title Defects. Borrower shall cure any title defects or exceptions which are not Excepted Liens raised by such information, or substitute acceptable Mortgaged Properties with no title defects or exceptions, except for Excepted Liens covering Mortgaged Properties of an equivalent value, within 60 days after a request by Agent or the Lenders to cure such defects or exceptions.

(b) Failure to Cure Title Defects. If Borrower is unable to cure any title defect requested by Agent or the Lenders to be cured within the 60 day period or Borrower does not comply with the requirements to provide acceptable title information covering at least (80%) of the value of the Oil and Gas Properties evaluated in the most recent Reserve Report that are Proven Reserves), such default shall not be a Default or an Event of Default, but instead Agent and the Lenders shall have the right to exercise the following remedy in their sole discretion from time to time, and any failure to so exercise this remedy at any time shall not be a waiver as to future exercise of the remedy by Agent or the Lenders. To the extent that Agent or the Lenders are not satisfied with title to any Mortgaged Property after the time period in Section 8.08(b) has elapsed, such unacceptable Mortgaged Property shall not count towards the minimum eighty percent (80%) requirement, and Agent may send a notice to Borrower and the Lenders that the then outstanding Borrowing Base shall be reduced by an amount as determined by all of the Lenders to cause Borrower to be in compliance with the requirement to provide acceptable title information on at least eighty percent (80%) of the value of the Oil and Gas Properties evaluated in the most recent Reserve Report that are Proven Reserves). This new Borrowing Base shall become effective immediately after receipt of such notice.

Section 8.09 Collateral.

(a) Collateral. The Obligations shall be secured by a perfected first priority Lien (subject only to Excepted Liens) granted to Agent for the benefit of the Beneficiaries in (i) all of Borrower’s and each Subsidiary’s rights, titles and interests, now owned or hereafter acquired, in any Oil and Gas Properties (and all contracts and any other rights related thereto), other than any Properties of de minimis value as determined by the Agent in its sole discretion (provided, however, in no event shall such Lien cover less than eighty percent (80%) of the value of the Oil and Gas Properties evaluated in the most recent Reserve Report that are Proven Reserves), (ii) all personal Property of Borrower and each Guarantor, and (iii) all rights, titles and interests of the equity of all of the Capital Securities of Borrower and Borrower’s Subsidiaries, and any Subsidiaries created or acquired after the Closing Date.

Agent is authorized to release any Collateral that is permitted to be sold or released pursuant to the terms of the Loan Documents.

Section 11.02 Reliance by Agent Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by the proper Person. Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper Person, and shall not incur any liability for relying thereon. In determining compliance with any condition hereunder to the making of a Loan, or the issuance, extension, renewal or increase of a Letter of Credit, that by its terms must be fulfilled to the satisfaction of a Lender or Issuing Bank, Agent may presume that such condition is satisfactory to such Lender or Issuing Bank unless Agent shall have received notice to the contrary from such Lender or Issuing Bank prior to the making of such Loan or the issuance of such Letter of Credit. In connection with taking any action pursuant to this Agreement, Agent may consult with legal counsel (who may be counsel for Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts, and such legal counsel, accountants and/or experts shall be afforded all of the indemnities and other protections afforded to Agent pursuant to Article XI.

Section 11.03 Default Agent shall not be deemed to have knowledge of the occurrence of a Default unless Agent has received notice from a Lender, Issuing Bank or Borrower specifying such Default and stating that such notice is a “Notice of Default.” Agent shall take such action with respect to such Default or Event of Default as may be requested by the Majority Lenders (or all or such other portion of the Lenders as shall be prescribed by this Agreement) in accordance with the terms hereof. Unless and until Agent has received any such request, 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 interests of the Lenders.

Section 11.04 Rights as a Lender The Person serving as Agent hereunder shall have the same rights and powers under the Loans Documents as any other Lender and may exercise or refrains from exercising the same as though it were not acting as the Agent, and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated or unless the context otherwise requires, include the Person serving as Agent hereunder in its individual capacity. Such Person and its Affiliates may accept deposits from, lend money to, invest in, own securities of, act as the financial advisor or in any other advisory capacity for, and generally engage in any kind of business with, Borrower or any Subsidiary or other Affiliate thereof as if such Person were not Agent hereunder and without any duty to account therefor to the Lenders, and such Person and its Affiliates may accept fees and other consideration from Borrower for services in connection with this Agreement or otherwise without having to account for the same to the Lenders.

Section 11.05 INDEMNIFICATION THE LENDERS AGREE TO INDEMNIFY AGENT AND ISSUING BANK RATABLY IN ACCORDANCE WITH THEIR PERCENTAGE SHARES FOR THE INDEMNITY MATTERS AS DESCRIBED IN SECTION 12.03 TO THE EXTENT NOT INDEMNIFIED OR REIMBURSED BY BORROWER UNDER SECTION 12.03, BUT WITHOUT LIMITING THE OBLIGATIONS OF BORROWER UNDER SAID SECTION 12.03 AND FOR ANY AND ALL OTHER LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES OR DISBURSEMENTS OF ANY KIND AND NATURE WHATSOEVER WHICH MAY BE IMPOSED ON, INCURRED BY OR ASSERTED AGAINST AGENT OR ISSUING BANK IN ANY WAY RELATING TO OR ARISING OUT OF: (I) THIS AGREEMENT, THE OTHER LOAN DOCUMENTS OR ANY OTHER DOCUMENTS CONTEMPLATED BY OR REFERRED TO HEREIN OR THE TRANSACTIONS CONTEMPLATED HEREBY, BUT EXCLUDING, UNLESS A DEFAULT HAS OCCURRED AND IS CONTINUING, NORMAL ADMINISTRATIVE COSTS AND EXPENSES INCIDENT TO THE PERFORMANCE OF ITS AGENCY DUTIES HEREUNDER OR (II) THE ENFORCEMENT OF ANY OF THE TERMS OF THIS AGREEMENT, ANY LOAN DOCUMENT OR OF ANY SUCH OTHER DOCUMENTS; WHETHER OR NOT ANY OF THE FOREGOING SPECIFIED IN THIS SECTION 11.05 ARISES FROM THE SOLE OR CONCURRENT NEGLIGENCE OF AGENT OR ISSUING BANK, PROVIDED THAT NO LENDER SHALL BE LIABLE FOR ANY OF THE FOREGOING TO THE EXTENT THEY ARISE FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF AGENT.

Section 11.06 Non-Reliance on Agent and other Lenders Each Lender and Issuing Bank acknowledges and agrees that it has, independently and without reliance on Agent or any other Lender or any of their Related Parties and based on such documents and information as it has deemed appropriate, made its own credit analysis of Borrower and its decision to enter into this Agreement, and that it will, independently and without reliance upon Agent or any other Lender or any of their Related Parties, and based on such documents and information as it shall deem appropriate at the time, continue to make its own analysis and decisions in taking or not taking action under or based upon this Agreement, any other Loan Document or any related agreement or any document furnished hereunder or thereunder. Agent shall not be required to keep itself informed as to the performance or observance by Borrower of this Agreement, the Notes, any other Loan Document or any other document referred to or provided for herein or to inspect the properties or books of Borrower. Except for notices, reports and other documents and information expressly required to be furnished to the Lenders by Agent hereunder, Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the affairs, financial condition or business of Borrower (or any of its Affiliates) which may come into the possession of Agent or any of its Affiliates. In this regard, each Lender acknowledges that Xxxxxx and Xxxxx, LLP is acting in this transaction as special counsel to Agent only. Each Lender will consult with its own legal counsel to the extent that it deems necessary in connection with the Loan Documents and the matters contemplated therein.

Section 11.07 Action by Agent; Delegation of Duties. Agent shall not be liable for any action taken or not taken by it (i) with the consent or at the request of the Majority Lenders (or such other number or percentage of the Lenders as shall be necessary, or as Agent shall believe in good faith shall be necessary, under the circumstances as provided in Section 10.02 and Section 12.04 ), and (ii) in the absence of its own gross negligence or willful misconduct as determined by a court of competent jurisdiction by final and nonappealable judgment. The instructions of the Majority Lenders (or all of the Lenders as expressly required by Section 12.04) and any action taken or failure to act pursuant thereto by Agent shall be binding on all of the Lenders. If a Default has occurred and is continuing, Agent shall take such action with respect to such Default as shall be directed by the Majority Lenders (or all of the Lenders as required by Section 12.04) in the written instructions (with indemnities) described in this Section 11.07, provided that, unless and until Agent shall have received such directions, Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default as it shall deem advisable in the best interests of the Lenders. In no event, however, shall Agent be required to take any action which exposes Agent to personal liability or which is contrary to this Agreement and the other Loan Documents or applicable law. Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other Loan Document by or through any one or more sub-agents appointed by Agent. Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions of this Article shall apply to any such sub-agent and to the Related Parties of Agent and any such sub-agent, and shall apply to their respective activities in connection with the syndication of the credit facility created by this Agreement, as well as activities as Agent. Agent shall not be responsible for the negligence or misconduct of any sub-agents except to the extent that a court of competent jurisdiction determines in a final and nonappealable judgment that Agent acted with gross negligence or willful misconduct in the selection of such sub-agents.

Section 11.08 Resignation of Agent

(a) Agent may at any time give notice of its resignation to the Lenders, Issuing Bank and Borrower. Upon receipt of any such notice of resignation, the Majority Lenders shall have the right, in consultation with Borrower, to appoint a successor. If no such successor shall have been so appointed by the Majority Lenders and shall have accepted such appointment within 30 days after the retiring Agent gives notice of its resignation (or such earlier day as shall be agreed by the Majority Lenders) (the “Resignation Effective Date”), then the retiring Agent may (but shall not be obligated to), on behalf of the Lenders and Issuing Bank, appoint a successor Agent. Whether or not a successor has been appointed, such resignation shall become effective in accordance with such notice on the Resignation Effective Date.

(b) If the Person serving as Agent is a Defaulting Lender pursuant to clause (d) of the definition thereof, the Majority Lenders may, to the extent permitted by applicable law, by notice in writing to Borrower and such Person remove such Person as Agent and, in consultation with Borrower, appoint a successor. If no such successor shall have been so appointed by the Majority Lenders and shall have accepted such appointment within 30 days (or such earlier day as shall be agreed by the Majority Lenders) (the “Removal Effective Date”), then such removal shall nonetheless become effective in accordance with such notice on the Removal Effective Date.

(c) With effect from the Resignation Effective Date or the Removal Effective Date (as applicable) (1) the retiring or removed Agent shall be discharged from its duties and obligations hereunder and under the other Loan Documents (except that in the case of any collateral security held by Agent on behalf of the Lenders or Issuing Bank under any of the Loan Documents, the retiring or removed Agent shall continue to hold such collateral security until such time as a successor Agent is appointed) and (2) except for any indemnity payments owed to the retiring or removed Agent, all payments, communications and determinations provided to be

made by, to or through Agent shall instead be made by or to each Lender and Issuing Bank directly, until such time, if any, as the Majority Lenders appoint a successor Agent as provided for above. Upon the acceptance of a successor’s appointment as Agent hereunder, such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring or removed Agent (other than any rights to indemnity payments owed to the retiring or removed Agent), and the retiring or removed Agent shall be discharged from all of its duties and obligations hereunder or under the other Loan Documents. The fees payable by Borrower to a successor Agent shall be the same as those payable to its predecessor unless otherwise agreed between Borrower and such successor. After the retiring or removed Agent’s resignation or removal hereunder and under the other Loan Documents, the provisions of this Article and Section 12.03 shall continue in effect for the benefit of such retiring or removed Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while the retiring or removed Agent was acting as Agent.

Section 11.09 Authorization to Execute other Loan Documents, Releases, Etc.

Each Lender (on behalf of itself and its Affiliates that are Approved Counterparties) and Issuing Bank irrevocably authorize Agent, at its option and in its discretion:

(a) to execute on behalf of such Lender all Loan Documents to which it is a party (other than this Agreement) on its behalf and to take such actions as Agent on its behalf and to exercise such powers under the Loan Documents as are delegated to Agent by the terms thereof, together with all such powers as are reasonably incidental thereto;

(b) to release any Lien on any property granted to or held by Agent under any Loan Document (x) upon termination of all Commitments and payment in full of all Obligations (other than contingent indemnification obligations) and the expiration or termination of all Letters of Credit (other than Letters of Credit as to which other arrangements satisfactory to Agent and Issuing Bank shall have been made), (y) that is sold or otherwise disposed of or to be sold or otherwise disposed of as part of or in connection with any sale or other disposition permitted under the Loan Documents, or (z) subject to Section 12.04, if approved, authorized or ratified in writing by the Majority Lenders;

(c) to release any Guarantor from its obligations under the Guaranty if such Person ceases to be a Subsidiary as a result of a transaction permitted under the Loan Documents; and

(d) subject to the terms of Section 12.04 and to the terms of the other Loan Documents, amend, modify, or waive any provisions of this Agreement or the other Loan Documents on behalf of Lenders.

Upon request by Agent at any time, the Majority Lenders will confirm in writing Agent’s authority to release its interest in particular types or items of property, or to release any Guarantor from its obligations under the Guaranty pursuant to this Section 11.09. Agent shall not be responsible for or have a duty to ascertain or inquire into any representation or warranty regarding the existence, value or collectability of the Collateral, the existence, priority or perfection of Agent’s Lien thereon, or any certificate prepared by any Loan Party in connection therewith, nor shall Agent be responsible or liable to the Lenders for any failure to monitor or maintain any portion of the Collateral.

Section 11.10 Agent May File Proofs of Claim.

In case of the pendency of any proceeding under any Debtor Relief Law or any other judicial proceeding relative to any Loan Party, Agent (irrespective of whether the principal of any Loan or Letter of Credit Obligation shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether Agent shall have made any demand on Borrower) shall be entitled and empowered (but not obligated) 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, Letters of Credit and all other Obligations 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, Issuing Bank and Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders, Issuing Bank and Agent and their respective agents and counsel and all other amounts due the Lenders, Issuing Bank and Agent under this Agreement) 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 Agent and, in the event that Agent shall consent to the making of such payments directly to the Lenders and Issuing Bank, to pay to Agent any amount due for the reasonable compensation, expenses, disbursements and advances of Agent and its agents and counsel, and any other amounts due Agent under this Agreement.

Section 11.11 Agency for Perfection.

Agent and each Lender hereby appoint each other Lender as agent for the purpose of perfecting Agent’s security interest in assets which, in accordance with the Uniform Commercial Code in any applicable jurisdiction, can be perfected by possession or control. Should any Lender (other than Agent) obtain possession or control of any such assets, such Lender shall notify Agent thereof, and, promptly upon Agent’s request therefor, shall deliver such assets to Agent or in accordance with Agent’s instructions or transfer control to Agent in accordance with Agent’s instructions. Each Lender agrees that it will not have any right individually to enforce or seek to enforce any Security Instrument or to realize upon any Collateral for the Obligations unless instructed to do so by Agent, it being understood and agreed that such rights and remedies may be exercised only by Agent.

Section 11.12 Right to Perform, Preserve and Protect.

If any Loan Party fails to perform any obligation hereunder or under any other Loan Document Agent itself may, but shall not be obligated to, cause such obligation to be performed at Borrower’s expense. Agent is further authorized by Borrower and the Lenders to make expenditures from time to time which Agent, in its reasonable business judgment, deems necessary or desirable to (a) preserve or protect the business conducted by Borrower, the Collateral, or any portion thereof and/or (b) enhance the likelihood of, or maximize the amount of, repayment of the Loans and other Obligations. Borrower hereby agrees to reimburse Agent on demand for any and all costs, liabilities and obligations incurred by Agent pursuant to this Section 11.12. Each Lender hereby agrees to indemnify Agent upon demand for any and all costs, liabilities and obligations incurred by Agent pursuant to this Section 11.12.

Section 11.13 Additional Titled Agents.

Except for rights and powers, if any, expressly reserved under this Agreement to any bookrunner, arranger or to any titled agent named on the cover page of this Agreement, other than Agent (collectively, the “Additional Titled Agents”), and except for obligations, liabilities, duties and responsibilities, if any, expressly assumed under this Agreement by any Additional Titled Agent, no Additional Titled Agent, in such capacity, has any rights, powers, liabilities, duties or responsibilities hereunder or under any of the other Loan Documents. Without limiting the foregoing, no Additional Titled Agent shall have nor be deemed to have a fiduciary relationship with any Lender. At any time that any Lender serving as an Additional Titled Agent shall have transferred to any other Person (other than any Affiliates) all of its interests in the Loans and in the Commitment, such Lender shall be deemed to have concurrently resigned as such Additional Titled Agent.

ARTICLE XII.

MISCELLANEOUS

Section 12.01 Waiver No failure on the past of Agent or any Lender to exercise and no delay in exercising, and no course of dealing with respect to, any 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.

(b) Assignments by Lenders. Any Lender may at any time assign to one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it); provided that any such assignment shall be subject to the following conditions:

(i) Minimum Amounts.

(1) in the case of an assignment of the entire remaining amount of the assigning Lender’s Commitment and/or the Loans at the time owing to it or contemporaneous assignments to related Approved Funds that equal at least the amount specified in paragraph (b)(i)(2) of this Section in the aggregate or in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund, no minimum amount need be assigned; and

(2) in any case not described in paragraph (b)(i)(1) of this Section, the aggregate amount of the Commitment (which for this purpose includes Loans

outstanding thereunder) or, if the applicable Commitment is not then in effect, the principal outstanding balance of the Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment with respect to such assignment is delivered to Agent or, if “Trade Date” is specified in the Assignment, as of the Trade Date) shall not be less than $5,000,000, unless each of Agent and, so long as no Default has occurred and is continuing, Borrower otherwise consents.

(ii) Proportionate Amounts. Each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement with respect to the Loan or the Commitment assigned.

(iii) Required Consents. No consent shall be required for any assignment except to the extent required by paragraph (b)(i)(2) of this Section and, in addition:

(1) the consent of Borrower (such consent not to be unreasonably withheld or delayed) shall be required unless (x) a Default has occurred and is continuing at the time of such assignment, or (y) such assignment is to a Lender, an Affiliate of a Lender or an Approved Fund; provided that Borrower shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to Agent within five (5) Business Days after having received notice thereof;

(2) the consent of Agent (such consent not to be unreasonably withheld or delayed) shall be required if such assignment is to a Person that is not a Lender, an Affiliate of such Lender or an Approved Fund with respect to such Lender; and

(3) the consent of Issuing Bank shall be required.

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

(v) No Assignment to Certain Persons. No such assignment shall be made to (1) Borrower or any of Borrower’s Affiliates or Subsidiaries or (2) to any Defaulting Lender or any of its Subsidiaries, or any Person who, upon becoming a Lender hereunder, would constitute any of the foregoing Persons described in this clause (2).

(vi) No Assignment to Natural Persons. No such assignment shall be made to a natural Person.

(vii) Certain Additional Payments. In connection with any assignment of rights and obligations of any Defaulting Lender hereunder, no such assignment shall be effective unless and until, in addition to the other conditions thereto set forth herein, the parties to the assignment shall make such additional payments to Agent in an aggregate amount sufficient, upon distribution thereof as appropriate (which may be outright payment, purchases by the assignee of participations or subparticipations, or other compensating actions, including funding, with the consent of Borrower and Agent, the applicable pro rata share of Loans previously requested but not funded by the Defaulting

Lender, to each of which the applicable assignee and assignor hereby irrevocably consent), to (1) pay and satisfy in full all payment liabilities then owed by such Defaulting Lender to Agent, Issuing Bank and each other Lender hereunder (and interest accrued thereon), and (2) acquire (and fund as appropriate) its full pro rata share of all Loans and participations in Letters of Credit in accordance with its Percentage Share. Notwithstanding the foregoing, in the event that any assignment of rights and obligations of any Defaulting Lender hereunder shall become effective under applicable law without compliance with the provisions of this paragraph, then the assignee of such interest shall be deemed to be a Defaulting Lender for all purposes of this Agreement until such compliance occurs.

Subject to acceptance and recording thereof by Agent pursuant to paragraph (c) of this Section, from and after the effective date specified in each Assignment, the assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment, 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, be released from its obligations under this Agreement (and, in the case of an Assignment 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 Sections 4.06, 5.01, 5.05 and 12.03 with respect to facts and circumstances occurring prior to the effective date of such assignment; provided, that except to the extent otherwise expressly agreed by the affected parties, no assignment by a Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this paragraph shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (d) of this Section.

(c) Agent, acting solely for this purpose as an agent of Borrower, shall maintain a copy of each Assignment delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts (and stated interest) of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive absent manifest error, and Borrower, Agent and the Lenders shall 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. The Register shall be available for inspection by Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(d) Participations. Any Lender may at any time, without the consent of, or notice to, Borrower or Agent, sell participations to any Person (other than a natural Person or Borrower or any of Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, and (iii) Borrower, Agent, Issuing Bank and the Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. For the avoidance of doubt, each Lender shall be responsible for the indemnity under Section 11.05 (d) with respect to any payments made by such Lender to its Participant(s).

Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any

amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver that requires the consent of all Lenders that affects such Participant. Borrower agrees that each Participant shall be entitled to the benefits of Sections 4.06, 5.01 and 5.05 (subject to the requirements and limitations therein, including the requirements under Section 4.06 (it being understood that the documentation required under Section 4.06 shall be delivered to the participating Lender)) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section; provided that such Participant (A) agrees to be subject to the provisions of Section 5.06 as if it were an assignee under paragraph (b) of this Section; and (B) shall not be entitled to receive any greater payment under Sections 4.06, 5.01 and 5.05, with respect to any participation, than its participating Lender would have been entitled to receive, except to the extent such entitlement to receive a greater payment results from a Regulatory Change that occurs after the Participant acquired the applicable participation. Each Lender that sells a participation agrees, at the Borrower's request and expense, to use reasonable efforts to cooperate with the Borrower to effectuate the provisions of Section 5.06 with respect to any Participant. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 4.05(a) as though it were a Lender; provided that such Participant agrees to be subject to Section 4.05(b) as though it were a Lender. Each Lender that sells a participation shall, acting solely for this purpose as an agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Loans or other obligations under the Loan Documents (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any Participant or any information relating to a Participant's interest in any commitments, loans, letters of credit or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such commitment, loan, letter of credit or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, Agent (in its capacity as Agent) shall have no responsibility for maintaining a Participant Register.

(e) Certain Pledges. 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; provided that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

(f) Notwithstanding any other provisions of this Section 12.06, no transfer or assignment of the interests or obligations of any Lender or any grant of participations therein shall be permitted if such transfer, assignment or grant would require Borrower to file a registration statement with the SEC or to qualify the Loans under the “Blue Sky” laws of any state.

Section 12.07 Defaulting Lenders

(a) Defaulting Lender Adjustments. Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a Defaulting Lender, then to the extent permitted by applicable law the following provisions shall apply for so long as such Lender is a Defaulting Lender:

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

(ii) Defaulting Lender Waterfall. Any payment of principal, interest, fees or other amounts received by Agent for the account of such Defaulting Lender (whether voluntary or mandatory, at maturity, pursuant to Article X or otherwise) or received by Agent from a Defaulting Lender pursuant to Section 4.05(b) shall be applied at such time or times as may be determined by Agent as follows: first, to the payment of any amounts owing by such Defaulting Lender to Agent hereunder; second, to the payment on a pro rata basis of any amounts owing by such Defaulting Lender to Issuing Bank hereunder; third, to Cash Collateralize the Issuing Banks’ Fronting Exposure with respect to such Defaulting Lender in accordance with Section 12.07(e); fourth, as Borrower may request (so long as no Default or Event of Default exists), to the funding of any Loan in respect of which such Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by Agent; fifth, if so determined by Agent and Borrower, to be held in a deposit account and released pro rata in order to (x) satisfy such Defaulting Lender’s potential future funding obligations with respect to Loans under this Agreement and (y) Cash Collateralize Issuing Bank’s future Fronting Exposure with respect to such Defaulting Lender with respect to future Letters of Credit issued under this Agreement, in accordance with Section 12.07(e); sixth, to the payment of any amounts owing to Agent, the Lenders or Issuing Bank as a result of any judgment of a court of competent jurisdiction obtained by Agent, any Lender or Issuing Bank against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; seventh, so long as no Default or Event of Default exists, to the payment of any amounts owing to Borrower as a result of any judgment of a court of competent jurisdiction obtained by Borrower against such Defaulting Lender as a result of such Defaulting Lender's breach of its obligations under this Agreement; and eighth, to such Defaulting Lender or as otherwise directed by a court of competent jurisdiction; provided that if (x) such payment is a payment of the principal amount of any Loans or disbursements under Letters of Credit in respect of which such Defaulting Lender has not fully funded its appropriate share, and (y) such Loans were made or the related Letters of Credit were issued at a time when the conditions set forth in Section 6.02 were satisfied or waived, such payment shall be applied solely to pay the Loans of, and Letter of Credit disbursements owed to, all Non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Loans of, or Letter of Credit disbursements owed to, such Defaulting Lender until such time as all Loans and funded and unfunded participations in Letters of Credit are held by the Lenders pro rata in accordance with the Commitments without giving effect to Section 12.07(a)(iv). Any payments, prepayments or other amounts paid or payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender or to post Cash Collateral pursuant to this Section 12.07(a)(ii) shall be deemed paid to and redirected by such Defaulting Lender, and each Lender irrevocably consents hereto.

(iii) Certain Fees. No Defaulting Lender shall be entitled to receive any unused Commitment fee pursuant to Section 2.04(a) for any period during which that Lender is a Defaulting Lender (and Borrower shall not be required to pay any such fee that otherwise would have been required to have been paid to that Defaulting Lender);

(iv) Reallocation of Participations to Reduce Fronting Exposure. All or any part of such Defaulting Lender’s participation in Letters of Credit shall be reallocated

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

(v) Cash Collateral. If the reallocation described in clause (iv) above cannot, or can only partially, be effected, Borrower shall, without prejudice to any right or remedy available to it hereunder or under law, Cash Collateralize Issuing Bank’s Fronting Exposure in accordance with the procedures set forth in Section 12.07(e).

(b) Defaulting Lender Cure. If Borrower, Agent and Issuing Bank agree in writing that a Lender is no longer a Defaulting Lender, Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include arrangements with respect to any Cash Collateral), that Lender will, to the extent applicable, purchase at par that portion of outstanding Loans of the other Lenders or take such other actions as Agent may determine to be necessary to cause the Loans and funded and unfunded participations in Letters of Credit to be held pro rata by the Lenders in accordance with the Commitments (without giving effect to Section 12.07(a)(iv)), whereupon such Lender will cease to be a Defaulting Lender; provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of Borrower while that Lender was a Defaulting Lender; and provided, further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender.

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

(d) Replacement of Defaulting Lenders. If any Lender becomes a Defaulting Lender, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 12.06), 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 Agent (and if any Commitment is being assigned, the Issuing Bank), which consent shall not unreasonably be withheld, and (ii) such Lender shall have received payment of an amount equal to the outstanding principal of its Loans and participations in disbursements under Letters of Credit, accrued interest thereon, accrued fees and all other amounts payable to it hereunder, from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts). A Defaulting Lender shall not be required to make any such assignment and delegation if, prior thereto, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

(e) Cash Collateral. At any time that there shall exist a Defaulting Lender, within one Business Day following the written request of Agent or Issuing Bank (with a copy to Agent) Borrower shall Cash Collateralize Issuing Bank’s Fronting Exposure with respect to such Defaulting Lender (determined after giving effect to Section 12.07(a)(iv) and any Cash Collateral provided by such Defaulting Lender) in an amount not less than the Minimum Collateral Amount.

(i) Grant of Security Interest. Borrower, and to the extent provided by any Defaulting Lender, such Defaulting Lender, hereby grants to Agent, for the benefit of Issuing Bank, and agrees to maintain, a first priority security interest in all such Cash Collateral as security for the Defaulting Lenders’ obligation to fund participations in respect of Letters of Credit, to be applied pursuant to clause (ii) below. If at any time Agent determines that Cash Collateral is subject to any right or claim of any Person other than Agent and Issuing Bank as herein provided, or that the total amount of such Cash Collateral is less than the Minimum Collateral Amount, Borrower will, promptly upon demand by Agent, pay or provide to Agent additional Cash Collateral in an amount sufficient to eliminate such deficiency (after giving effect to any Cash Collateral provided by the Defaulting Lender).

(ii) Application. Notwithstanding anything to the contrary contained in this Agreement, Cash Collateral provided under this Section 12.07 in respect of Letters of Credit shall be applied to the satisfaction of the Defaulting Lender’s obligation to fund participations in respect of Letters of Credit (including, as to Cash Collateral provided by a Defaulting Lender, any interest accrued on such obligation) for which the Cash Collateral was so provided, prior to any other application of such property as may otherwise be provided for herein.

(iii) Termination of Requirement. Cash Collateral (or the appropriate portion thereof) provided to reduce Issuing Bank’s Fronting Exposure shall no longer be required to be held as Cash Collateral pursuant to this Section 12.07(e) following (i) the elimination of the applicable Fronting Exposure (including by the termination of Defaulting Lender status of the applicable Lender), or (ii) the determination by Agent and Issuing Bank that there exists excess Cash Collateral; provided that, subject to Section 12.07 the Person providing Cash Collateral and each Issuing Bank may agree that Cash Collateral shall be held to support future anticipated Fronting Exposure or other obligations and provided further that to the extent that such Cash Collateral was provided by Borrower, such Cash Collateral shall remain subject to the security interest granted pursuant to the Loan Documents.

Section 12.08 Invalidity In the event that any one or more of the provisions contained in any of the Loan Documents, the Letters of Credit or the Letter of Credit Agreements shall, for any reason, be held invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provision of the Notes, this Agreement or any other Loan Document.

Section 12.09 Counterparts; Delivery of Electronic Signature Page This Agreement may be executed in any number of counterparts, all of which taken together shall constitute one and the same instrument and any of the parties hereto may execute this Agreement by signing any such counterpart. Delivery of an executed signature page of this Agreement and the other Loan Documents by telecopier, email or other electronic means shall be effective as delivery of an original executed signature page of this Agreement and such other Loan Documents and shall be binding on the parties hereto and thereto. Any party delivering an executed counterpart signature

page of this Agreement and any other Loan Documents by electronic means shall also physically deliver original executed counterpart signature pages of this Agreement and such other Loan Documents in the manner and quantity as requested by Agent or Agent’s counsel, but the failure to physically deliver such original executed counterpart signature pages shall not affect the validity, enforceability, and binding effect of this Agreement or such other Loan Documents.

Section 12.10 Survival The obligations of the parties under Section 4.06, Article V, and Sections 11.05 and 12.03 shall survive the repayment of the Loans and the termination of the Commitments. To the extent that any payments on the Obligations or proceeds of any Collateral are subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be repaid to a trustee, debtor in possession, receiver or other Person under any bankruptcy law, common law or equitable cause, then to such extent, the Obligations so satisfied shall be revived and continue as if such payment or proceeds had not been received and Agent’s and the Lenders’ Liens, security interests, rights, powers and remedies under this Agreement and each of the other Loan Documents shall continue in full force and effect. In such event, each Loan Document shall be automatically reinstated and Borrower shall take such action as may be reasonably requested by Agent and the Lenders to effect such reinstatement.

Section 12.11 Captions Captions and section headings appearing herein are included solely for convenience of reference and are not intended to affect the interpretation of any provision of this Agreement.

Section 12.12 NO ORAL AGREEMENTS THE LOAN DOCUMENTS EMBODY THE ENTIRE AGREEMENT AND UNDERSTANDING BETWEEN THE PARTIES AND SUPERSEDE ALL OTHER AGREEMENTS AND UNDERSTANDINGS BETWEEN SUCH PARTIES RELATING TO THE SUBJECT MATTER HEREOF AND THEREOF. THE LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

Section 12.13 GOVERNING LAW; SUBMISSION TO JURISDICTION.

(a) THIS AGREEMENT, EACH NOTE AND EACH OTHER LOAN DOCUMENT, AND ALL MATTERS RELATING HERETO OR THERETO OR ARISING THEREFROM (WHETHER SOUNDING IN CONTRACT LAW, TORT LAW OR OTHERWISE), SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF TEXAS, WITHOUT REGARD TO CONFLICTS OF LAWS PRINCIPLES, EXCEPT TO THE EXTENT THAT UNITED STATES FEDERAL LAW PERMITS ANY LENDER TO CHARGE INTEREST AT THE RATE ALLOWED BY THE LAWS OF THE STATE WHERE SUCH LENDER IS LOCATED. CH. 346 OF THE TEXAS FINANCE CODE (WHICH REGULATES CERTAIN REVOLVING CREDIT LOAN ACCOUNTS AND REVOLVING TRI-PARTY ACCOUNTS) SHALL NOT APPLY TO THIS AGREEMENT OR THE NOTES.

(b) BORROWER HEREBY CONSENTS TO THE JURISDICTION OF ANY STATE OR FEDERAL COURT LOCATED WITHIN THE COUNTY OF XXXXXX, STATE OF TEXAS AND IRREVOCABLY AGREES THAT, SUBJECT TO AGENT’S ELECTION, ALL ACTIONS OR PROCEEDINGS ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE OTHER LOAN DOCUMENTS SHALL BE LITIGATED IN SUCH COURTS. BORROWER HEREBY IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING, WITHOUT LIMITATION, ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY SUCH ACTION OR PROCEEDING IN SUCH JURISDICTION. THIS SUBMISSION TO JURISDICTION IS NON-EXCLUSIVE AND

DOES NOT PRECLUDE AGENT OR ANY LENDER FROM OBTAINING JURISDICTION OVER BORROWER IN ANY COURT OTHERWISE HAVING JURISDICTION.

(c) BORROWER HEREBY IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OF ANY OF THE AFOREMENTIONED COURTS IN ANY SUCH ACTION OR PROCEEDING BY THE MAILING OF COPIES THEREOF BY REGISTERED OR CERTIFIED MAIL, POSTAGE PREPAID, TO BORROWER AT ITS SAID ADDRESS, SUCH SERVICE TO BECOME EFFECTIVE TEN (10) DAYS AFTER SUCH MAILING. NOTHING HEREIN SHALL AFFECT THE RIGHT OF AGENT, ANY LENDER OR ANY HOLDER OF A NOTE TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR TO COMMENCE LEGAL PROCEEDINGS OR OTHERWISE PROCEED AGAINST BORROWER OR ITS PROPERTIES IN ANY OTHER JURISDICTION.

(d) BORROWER, AGENT AND EACH LENDER HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THE LOAN DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED THEREBY AND AGREE THAT ANY SUCH ACTION OR PROCEEDING SHALL BE TRIED BEFORE A COURT AND NOT BEFORE A JURY. BORROWER, AGENT AND EACH LENDER ACKNOWLEDGES THAT THIS WAIVER IS A MATERIAL INDUCEMENT TO ENTER INTO A BUSINESS RELATIONSHIP, THAT EACH HAS RELIED ON THE WAIVER IN ENTERING INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS, AND THAT EACH WILL CONTINUE TO RELY ON THIS WAIVER IN THEIR RELATED FUTURE DEALINGS. BORROWER, AGENT AND EACH LENDER WARRANTS AND REPRESENTS THAT EACH HAS HAD THE OPPORTUNITY OF REVIEWING THIS JURY WAIVER WITH LEGAL COUNSEL, AND THAT EACH KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY TRIAL RIGHTS.

Section 12.14 Interest It is the intention of the parties hereto that each Lender shall conform strictly to usury laws applicable to it. Accordingly, if the transactions contemplated hereby would be usurious as to any Lender under laws applicable to it (including the laws of the United States of America and the State of Texas or any other jurisdiction whose laws may be mandatorily applicable to such Lender notwithstanding the other provisions of this Agreement), then, in that event, notwithstanding anything to the contrary in any of the Loan Documents or any agreement entered into in connection with or as security for the Notes, it is agreed as follows: (i) the aggregate of all consideration which constitutes interest under law applicable to any Lender that is contracted for, taken, reserved, charged or received by such Lender under any of the Loan Documents or agreements or otherwise in connection with the Notes shall under no circumstances exceed the maximum amount allowed by such applicable law, and any excess shall be canceled automatically and if theretofore paid shall be credited by such Lender on the principal amount of the Obligations (or, to the extent that the principal amount of the Obligations shall have been or would thereby be paid in full, refunded by such Lender to Borrower); and (ii) in the event that the maturity of the Notes is accelerated by reason of an election of the holder thereof resulting from any Event of Default under this Agreement or otherwise, or in the event of any required or permitted prepayment, then such consideration that constitutes interest under law applicable to any Lender may never include more than the maximum amount allowed by such applicable law, and excess interest, if any, provided for in this Agreement or otherwise shall be canceled automatically by such Lender as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited by such Lender on the principal amount of the Obligations (or, to the extent that the principal amount of the Obligations shall have been or would thereby be paid in full, refunded by such Lender to Borrower). All sums paid or agreed to be paid to any Lender for the use, forbearance or detention of sums due hereunder shall, to the extent permitted by law applicable to such Lender, be amortized, prorated, allocated and spread throughout the full term of the Loans evidenced by the Notes until payment in full so that the rate or

amount of interest on account of any Loans hereunder does not exceed the maximum amount allowed by such applicable law. If at any time and from time to time (i) the amount of interest payable to any Lender on any date shall be computed at the Highest Lawful Rate applicable to such Lender pursuant to this Section 12.14 and (ii) in respect of any subsequent interest computation period the amount of interest otherwise payable to such Lender would be less than the amount of interest payable to such Lender computed at the Highest Lawful Rate applicable to such Lender, then the amount of interest payable to such Lender in respect of such subsequent interest computation period shall continue to be computed at the Highest Lawful Rate applicable to such Lender until the total amount of interest payable to such Lender shall equal the total amount of interest which would have been payable to such Lender if the total amount of interest had been computed without giving effect to this Section 12.14. To the extent that Chapter 303 of the Texas Finance Code is relevant for the purpose of determining the Highest Lawful Rate, such Lender elects to determine the applicable rate ceiling under such Chapter by the indicated weekly rate ceiling from time to time in effect.

Section 12.15 Confidentiality In the event that Borrower provides to Agent or the Lenders confidential information belonging to Borrower, if Borrower shall (a) denominate any such written information as “confidential” or (b) preface the dissemination of any information communicated in any manner other than in writing as “confidential”, Agent and the Lenders shall thereafter maintain such information in confidence in accordance with the standards of care and diligence that each utilizes in maintaining its own confidential information. This obligation of confidence shall not apply to such portions of the information which (i) are in the public domain, (ii) hereafter become part of the public domain without Agent or the Lenders breaching their obligation of confidence to Borrower, (iii) are previously known by Agent or the Lenders from some source other than Borrower, (iv) are hereafter developed by Agent or the Lenders without using Borrower’s information, (v) are hereafter obtained by or available to Agent or the Lenders from a third party who owes no obligation of confidence to Borrower with respect to such information or through any other means other than through disclosure by Borrower, (vi) are disclosed with Borrower’s consent, (vii) must be disclosed either pursuant to any Governmental Requirement or to Persons regulating the activities of Agent or the Lenders, or (viii) as may be required by law or regulation or order of any Governmental Authority in any judicial, arbitration or governmental proceeding. Further, Agent or a Lender may disclose any such information to any other Lender, any independent petroleum engineers or consultants, any independent certified public accountants, any legal counsel employed by such Person in connection with this Agreement or any other Loan Document, including without limitation, the enforcement or exercise of all rights and remedies thereunder, or any assignee or participant (including prospective assignees and participants) in the Loans; provided, however, that Agent or the Lenders shall receive a confidentiality agreement from the Person to whom such information is disclosed such that said Person shall have the same obligation to maintain the confidentiality of such information as is imposed upon Agent or the Lenders hereunder. Notwithstanding anything to the contrary provided herein, this obligation of confidence shall cease three (3) years from the date the information was furnished, unless Borrower requests in writing at least thirty (30) days prior to the expiration of such three year period, to maintain the confidentiality of such information for an additional three year period. Borrower waives any and all other rights it may have to confidentiality as against Agent and the Lenders arising by contract, agreement, statute or law except as expressly stated in this Section 12.15.

Section 12.16 USA Patriot Act Each Lender hereby notifies Borrower that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”) is required to obtain, verify and record information that identifies Borrower, which information includes the name and address of Borrower and other information that will allow such Lender to identify Borrower in accordance with the Act.

Section 12.17 EXCULPATION PROVISIONS EACH OF THE PARTIES HERETO SPECIFICALLY AGREES THAT IT HAS A DUTY TO READ THIS AGREEMENT AND THE

OTHER LOAN DOCUMENTS AND AGREES THAT IT IS CHARGED WITH NOTICE AND KNOWLEDGE OF THE TERMS OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; THAT IT HAS IN FACT READ THIS AGREEMENT AND IS FULLY INFORMED AND HAS FULL NOTICE AND KNOWLEDGE OF THE TERMS, CONDITIONS AND EFFECTS OF THIS AGREEMENT; THAT IT HAS BEEN REPRESENTED BY INDEPENDENT LEGAL COUNSEL OF ITS CHOICE THROUGHOUT THE NEGOTIATIONS PRECEDING ITS EXECUTION OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; AND HAS RECEIVED THE ADVICE OF ITS ATTORNEY IN ENTERING INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; AND THAT IT RECOGNIZES THAT CERTAIN OF THE TERMS OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS RESULT IN ONE PARTY ASSUMING THE LIABILITY INHERENT IN SOME ASPECTS OF THE TRANSACTION AND RELIEVING THE OTHER PARTY OF ITS RESPONSIBILITY FOR SUCH LIABILITY. EACH PARTY HERETO AGREES AND COVENANTS THAT IT WILL NOT CONTEST THE VALIDITY OR ENFORCEABILITY OF ANY EXCULPATORY PROVISION OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS ON THE BASIS THAT THE PARTY HAD NO NOTICE OR KNOWLEDGE OF SUCH PROVISION OR THAT THE PROVISION IS NOT “CONSPICUOUS.”
