(iii) unless in the case of issuance of a new Letter of Credit, the borrower has delivered to the Issuing Bank a completed and executed Letter of Credit Application;

(iv) as to each requested Carve Out LCs, the Borrower must provide acceptable cash collateral, cash equivalent collateral or a back to back letter of credit from a reputable banking institution to the Agent, as beneficiary, acceptable to the Agent, the Issuing Bank and the Lenders providing not less than 100% coverage of the outstanding and unfunded amount thereof to the Agent for the benefit of the Issuing Bank and the Lenders in form, scope and substance acceptable to the Agent and the Issuing Bank not less than ninety (90) days prior to the Final Maturity Date; and

Section 2.02 Borrowings, Continuations and Conversions, Letters of Credit.

(a) Borrowings. The Borrower shall give the Agent (which shall promptly notify the Lenders) advance notice as hereinafter provided of each borrowing hereunder, which shall specify (i) the aggregate amount of such borrowing, (ii) the date (which shall be a Business Day) of the Loans to be borrowed, and (iii) the duration of the Interest Period for each LIBOR Loan.

Without in any way limiting the Borrower’s obligation to confirm in writing any telephonic notice, the Agent may act without liability upon the basis of telephonic notice believed by the Agent in good faith to be from the Borrower prior to receipt of written confirmation. In each such case, the Borrower hereby waives the right to dispute the Agent’s record of the terms of such telephonic notice except in the case of gross negligence or willful misconduct by the Agent. Agent shall promptly forward such notice of borrowing to each of the other Lenders on the same date of receipt thereof from the Borrower.

All or any part of any outstanding Loan may be converted as provided herein, provided that (i) any conversion of any permitted Base Rate Loan into a LIBOR Loan shall be (as to each such Loan into which there is a conversion for an applicable Interest Period) in amounts of at least $1,000,000.00 or any whole multiple of $500,000.00 in excess thereof and (ii) no Default shall have occurred and be continuing. If an Event of Default shall have occurred and be continuing, no permitted Base Rate Loan may be converted into a LIBOR Loan.

The amounts so received by the Agent shall, subject to the terms and conditions of this Agreement, be made available to the Borrower by depositing the same, in immediately available funds, in an account of the Borrower, designated by the Borrower and maintained at the Principal Office.

(g) Letters of Credit. The Borrower shall give the Issuing Bank (which shall promptly notify the Lenders of such request and their Percentage Share of such Letter of Credit), a Letter of Credit Application to be received by the Issuing Bank not later than 11:00 a.m. Tulsa, Oklahoma, time not less than two (2) Business Days prior thereto of each request for the issuance, and at least ten (10) Business Days prior to the date of the renewal or extension, of a Letter of Credit hereunder which request shall specify (i) the amount of such Letter of Credit, (ii) the date (which shall be a Business Day) such Letter of Credit is to be issued, renewed or extended, (iii) the duration thereof, (iv) the name and address of the beneficiary thereof, (v) the form and type of the Letter of Credit and (vi) such other information as the Issuing Bank may reasonably request, all of which shall be reasonably satisfactory to the Issuing Bank. Subject to the terms and conditions of this Agreement, on the date specified for the issuance, renewal or extension of a Letter of Credit, the Issuing Bank shall issue, renew or extend such Letter of Credit to the beneficiary thereof.

In conjunction with the issuance of each Letter of Credit, the Borrower and the Subsidiary, if the account party, shall execute a Letter of Credit Agreement. In the event of any conflict between any provision of a Letter of Credit Agreement and this Agreement, the Borrower, the Issuing Bank, the Agent and the Lenders hereby agree that the provisions of this Agreement shall govern.

Section 2.03 Changes of Revolving Credit Commitments.

(a) The Aggregate Revolving Credit Commitments shall at all times be equal to the lesser of (i) the Aggregate Maximum Revolving Credit Commitment Amounts after adjustments resulting from reductions pursuant to Sections 2.03(b), 2.07(b) or 2.08 or increases pursuant to Section 2.03(d) or (ii) the Borrowing Base as determined from time to time.

(b) Effective only as of each regularly scheduled semi-annual Redetermination Date, the Borrower shall have the right to reduce the amount of the Aggregate Maximum Revolving Credit Commitment Amounts at any time, or from time to time, upon not less than thirty (30) days’ prior written notice to the Agent of each such reduction, which notice shall specify the effective date thereof and the amount of any such reduction (which shall not be less than $5,000,000.00 or any whole multiple of $1,000,000.00 in excess thereof) and shall be irrevocable and effective only upon receipt by the Agent.

(d) The Aggregate Maximum Revolving Credit Commitment Amounts may be increased in accordance with the terms and provisions of Section 12.06(h) upon Additional Lenders becoming signatory parties hereto and/or one or more of the existing Lenders increasing the amount of such Lender’s Maximum Revolving Credit Commitment; provided, however, in no event shall the Aggregate Maximum Revolving Credit Commitment Amounts exceed $150,000,000.00 without the prior written consent of all of the Lenders, the Agent and the Borrower.

Section 2.04 Fees.

(a) Revolving Credit Commitment Fee/Loan Facility Fee. The Borrower shall pay to the Agent for the account of each Lender a Revolving Credit Commitment Fee on the daily average Aggregate Revolving Credit Commitments for the period from and including the Closing Date up to, but excluding, the earlier of the date the Aggregate Revolving Credit Commitments are terminated or the Final Maturity Date at a rate per annum equal to the amount reflected on the appropriate intersection in the table set forth in the definition of “Applicable Revolving Credit Commitment Fee,” subject to the then applicable Revolving Credit Commitment Fee Cap (which such Revolving Credit Commitment Fee Cap must be reset and modified by the Lenders as of each Redetermination Date (whether a regularly scheduled semi-annual Redetermination Date or an unscheduled Redetermination Date as requested by the Borrower or required by the Lenders in accordance with the terms, provisions and limitations of this Agreement). Accrued Revolving Credit Commitment Fees shall be payable quarterly in arrears on each Quarterly Date and on the earlier of the date the Aggregate Revolving Credit Commitments are terminated or the Final Maturity Date. The Borrower shall also pay to the Agent for the benefit of the Lenders (i) a loan facility fee in the amount of $37,500 (0.125% of the additional $30,000,000 in Revolving Credit Commitments established concurrently herewith), and (ii) a 0.125% loan facility fee for the Additional Lenders’ Revolving Credit Commitment amount or increase in the existing Lenders’ Revolving Credit Commitment amounts in accordance with the provisions of Sections 2.03(d) and 12.06(h), each of which such loan facility fee shall be deemed fully earned and non-refundable.

(b) Letter of Credit Fees.

(i) The Borrower agrees to pay the Agent, for the account of each Lender, commissions for issuing the Letters of Credit on the daily average outstanding of the maximum liability of the Issuing Bank existing from time to time under such Letter of Credit (calculated separately for each Letter of Credit) at the rate per annum equal 1.00% (subject to a minimum $500.00 issuance fee) plus standard and customary documentation and processing fees associated therewith. Each Letter of Credit shall be deemed to be outstanding up to the full face amount of the Letter of Credit until the Issuing Bank has received the canceled Letter of Credit or a written cancellation of the Letter of Credit from the beneficiary of such Letter of Credit in form and substance acceptable to the Issuing Bank in its sole discretion, or for any reductions in the amount of the Letter of Credit (other than from a drawing), written notification from the beneficiary of such Letter of Credit. Such commissions are payable quarterly in arrears on each Quarterly Date and upon cancellation or expiration of each such Letter of Credit.

(iii) Upon each drawing of any Letter of Credit, the Borrower shall pay to the Issuing Bank for its own account a negotiation fee in an amount which is in accordance with the Issuing Bank’s then-current Letter of Credit fee policy; provided that such fee shall not be a condition to any drawing.

(iv) Upon each amendment of any Letter of Credit, the Borrower shall pay to the Issuing Bank for its own account a sum in an amount which is in accordance with its then current Letter of Credit amendment fee policy or schedule.

Section 2.05 Several Obligations. The failure of any Lender to make any Loan to be made by it or to provide funds for disbursements or reimbursements under Letters of Credit on the date specified therefore shall not relieve any other Lender of its obligation to make its Loan or provide funds on such date, but no Lender shall be responsible for the failure of any other Lender to make a Loan to be made by such other Lender or to provide funds to be provided by such other Lender.

Section 2.06 Notes. The Loans made by each Lender shall be evidenced by a single promissory note of the Borrower in substantially the form of Exhibit A, dated (i) the Closing Date or (ii) the effective date of an Assignment pursuant to Section 12.06(b) or an Additional Lender or increase by an existing Lender pursuant to Section 12.06(h), as applicable, payable to the order of such Lender in a principal amount equal to its Maximum Revolving Credit Amount as originally in effect and otherwise duly completed and such substitute Notes as required by Sections 12.06(b) or 12.06(h), as applicable. The date, amount, Type, interest rate and Interest Period of each Loan made by each Lender, and all payments made on account of the principal thereof, shall be recorded by such Lender on its books for its Note, and, prior to any transfer may be endorsed by such Lender on the schedule attached to such Note or any continuation thereof or on any separate record maintained by such Lender. Failure to make any such notation or to attach a schedule shall not affect any Lender’s or the Borrower’s rights or obligations in respect of such Loans or affect the validity of such transfer by any Lender of its Note. Notwithstanding the aggregate face amount of the Notes issued from time to time to the order of the respective Lenders, in no event shall the sum of all (i) Loans advanced and outstanding hereunder plus (ii) unfunded amounts of unexpired Letters of Credit issued pursuant hereto exceed the Aggregate Maximum Revolving Credit Amounts in effect from time to time.

Section 2.07 Prepayments.

(a) Voluntary Prepayments. The Borrower may prepay the Base Rate Loans upon the same Business Day prior notice to the Agent not later than 11:00 o’clock a. m. (Tulsa, Oklahoma time), which Agent shall promptly notify the Lenders), which notice shall specify the prepayment date (which shall be a Business Day) and the amount of the prepayment (which shall be at least $1,000,000.00 and a multiple of $250,000.00 or the remaining aggregate principal balance outstanding on the Notes) and shall be irrevocable and effective only upon receipt by the Agent, provided that interest on the principal prepaid, accrued to the prepayment date, shall be paid on the prepayment date. The Borrower may prepay LIBOR Loans on the same conditions as for Base Rate Loans (except that prior notice to the Agent shall be not less than three (3) Business Days for LIBOR Loans) and in addition such prepayments of LIBOR Loans shall be subject to the terms of Section 5.05 and shall be in an amount equal to all of the LIBOR Loans for the Interest Period prepaid.

(b) Mandatory Prepayments.

(i) If, after giving effect to any reduction of the Aggregate Revolving Credit Commitments pursuant to Section 2.03(b), the outstanding aggregate principal amount of the Loans plus the LC Exposure exceeds the Aggregate Maximum Revolving Credit Amounts, the Borrower shall (i) prepay the Loans on the date of such 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 the 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) Upon any redetermination of the amount of the Borrowing Base in accordance with Section 2.08, if the redetermined Borrowing Base is less than the aggregate outstanding principal amount of the Loans plus the LC Exposure, then the Borrower shall within thirty (30) days of such Borrowing Base redetermination do one or any combination of the following: (i) prepay the Loans in an aggregate principal amount equal to such excess, together with interest on the principal amount paid accrued to the date of such prepayment, (ii) notify the Agent that Borrower will prepay, in equal monthly installments commencing thirty (30) days after such Borrowing Base redetermination and continuing on the same day the next four months (unless there is no corresponding day, in which event, it will be paid on the last day of such month), the Loans in an aggregate principal amount equal to such excess, together with interest on the principal amount paid accrued to the date of such prepayment; or (iii) promptly and in any event within thirty (30) days of notice of such Borrowing Base deficiency provide additional collateral acceptable to the Agent and all Lenders to increase the Borrowing Base to an amount at least equal to the aggregate outstanding principal amounts of the Loans, and if a Borrowing Base deficiency remains after prepaying all of the Loans because of LC Exposure, the Borrower shall pay to the Agent on behalf of the Lenders an amount equal to such Borrowing Base deficiency to be held as cash collateral as provided in Section 2.10(b).

(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 Revolving Credit Commitments.

Section 2.08 Borrowing Base.

(a) The Borrowing Base shall be determined in accordance with Section 2.08(b) by the Agent with the concurrence of the Lenders as provided in Section 2.08(b) and is subject to redetermination in accordance with Section 2.08(d). Upon any redetermination of the Borrowing Base and the concurrent modification of Schedule 2.08 to reflect such redetermination, such redetermination shall remain in effect until the next successive Redetermination Date. “Redetermination Date” shall mean the date that the redetermined Borrowing Base and Schedule 2.08 becomes effective subject to the notice requirements specified in Section 2.08(e) both for scheduled redeterminations and unscheduled redeterminations. So long as any of the Revolving Credit 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 Schedule 2.08. During the period from and after the Closing Date until the first redetermination pursuant to Section 2.08(d) or adjusted pursuant to Section 8.08(c), the amount of the Borrowing Base shall be $65,000,000.00, with such initial Borrowing Base to be available for general corporate purposes as approved by the Required Lenders, for drilling and development purposes and other capital expenditures, the issuance of standby letters of credit in accordance with the terms, conditions and limitations hereof and for acquisitions of Oil and Gas Properties, and to the extent required by Section 8.08, such properties must be mortgaged to the Agent by documents in form and substance satisfactory to Agent and applicable title information furnished satisfactory to Agent and subject to no liens or encumbrances of any kind whatsoever except those acceptable to Agent in Agent’s sole discretion.

(b) Upon receipt of the reports required by Section 8.07 and such other reports, data and supplemental information from the Borrower as may from time to time be reasonably requested by the Agent or the Lenders (collectively, the “Engineering Reports”) with respect to the Oil and Gas Properties included or to be included in the Borrowing Base, the Agent will redetermine the Borrowing Base and Schedule 2.08.

(i) Each Engineering Report will be satisfactory to Agent and the Lenders, will contain sufficient information to enable the Borrower to meet the reporting requirements concerning oil and gas Proven Reserves contained in Regulations S-K and S-X promulgated by the SEC, will take into account any “over/under produced” status under gas balancing arrangements, and will contain information and analysis comparable in scope to that contained in the Engineering Report most recently submitted to the Agent prior to the Closing Date and other information received by the Agent and the Lenders relating to the Proven Reserves of the Borrower and its Subsidiaries.

(ii) Such proposed redetermination initially will be submitted by the Agent for the approval of the Lenders as provided below, in accordance with their normal and customary procedures for evaluating oil and gas reserves and other related assets as such exist at that particular time. Each Lender, 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, practices, standards and policies (including pricing parameters, assumptions and methodology) for evaluating oil and gas reserves and other related assets as such exist at that particular time. The Agent shall propose to the Lenders a new Borrowing Base and Schedule 2.08 within thirty (30) days following receipt by the Agent and the Lenders of the Engineering Reports. Lenders holding 100% of the Aggregate Commitments must approve increases to the then existing Borrowing Base, while the approval of the Required Lenders is required to approve a decrease in, or maintain, such existing Borrowing Base.

(iii) After having received notice of such proposal by the Agent, all of the Lenders shall have ten (10) days to agree or disagree with such proposal. If at the end of such ten (10) days, no Lender shall have communicated its approval or disapproval of the proposed Borrowing Base and revised Schedule 2.08, such silence or lack of communication to the Agent shall be deemed to be an approval of the Agent’s proposed Borrowing Base, and the Agent’s proposal shall be the new Borrowing Base. If however, within the time prescribed by the preceding sentence, (i) all the Lenders have not approved (or have not been deemed to have approved) the Agent’s proposal with respect to an increase in the Borrowing Base, or (ii) the Required Lenders have not approved (or have not been deemed to have approved) the Agent’s proposal with respect to a decrease in, or maintenance of, the Borrowing Base, the Agent and, as applicable, any all the Lenders (with respect to an increase in the Borrowing Base) or the Required Lenders (with respect to a decrease in, or maintenance of, the Borrowing Base) shall, within an additional seven (7) days, diligently attempt in good faith to agree upon a new Borrowing Base and Schedule 2.08.

(iv) If the Agent and, as applicable, either all the Lenders or the Required Lenders cannot otherwise agree on a redetermination of the Borrowing Base within such additional seven (7) day period, then the proposed Borrowing Base shall be set at the lesser of (i) the Borrowing Base proposed by the Agent or (ii) the amount calculated by the Agent as the “weighted arithmetic average” (as hereinafter calculated) of the Borrowing Base, as determined by each individual Lender and communicated to the Agent in writing, and such Borrowing Base shall then become the Borrowing Base. However, the amount of the Borrowing Base shall never be increased at any time above or in excess of the then existing Borrowing Base without the unanimous written consent of all of the Lenders, notwithstanding anything else herein to the contrary. For purposes of this paragraph, the “weighted arithmetic average” of the Borrowing Base shall be determined by first multiplying the Borrowing Base proposed in writing to the Agent by each Lender by the ratio of such Lender’s Percentage Share over the sum of the Percentage Shares of all Lenders, and then adding the results of each such calculation, with the resultant sum being the Borrowing Base.

(v) Borrower acknowledges that the determination of the Borrowing Base contains an equity cushion (market value in excess of loan value), which is essential for the adequate protection of the Agent and the Lenders. No Proven Reserves shall be included or considered for inclusion in the Borrowing Base unless the Agent and the Lenders shall have received, at Borrower’s expense, the title data and information otherwise required in this Agreement.

(c) The 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 information is not reasonably satisfactory, such Property is not Mortgaged Property or such Property is not assignable.

(d) So long as any of the Revolving Credit Commitments are in effect and until payment in full of all Loans hereunder, on or around the last day of each March and September, commencing September 30, 2006, (each such semi-annual date, together with each unscheduled redetermination thereof as requested by the Borrower or required by the Agent and the Lenders in accordance with the terms, provisions and limitations hereof, being a “Redetermination Date”), the Lenders shall redetermine the amount of the Borrowing Base in accordance with Section 2.08(b). In addition, the Borrower may initiate one unscheduled redetermination of the Borrowing Base between each semi-annual scheduled Redetermination Date if the Borrower acquires additional Oil and Gas Properties by specifying in writing to the non-initiating party the date on which Borrower is to furnish a Reserve Report in accordance with Section 8.07(b) and the date as of which such redetermination is to occur. The Agent and the other Lenders reserve the right to schedule additional redeterminations from time to time in addition, but not in lieu of, the semi-annual scheduled Redetermination Dates.

(e) The Agent shall promptly notify in writing the Borrower and the Lenders of the new Borrowing Base. Any redetermination of the Borrowing Base shall not be in effect until written notice thereof is sent by the Agent to the Borrower.

Section 2.09 Assumption of Risks. The 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 the Issuing Bank (except in the case of gross negligence or willful misconduct on the part of the 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 the Issuing Bank’s control or the control of the Issuing Bank’s correspondents. In addition, neither the Issuing Bank, the Agent nor any Lender shall be responsible for any error, neglect, or default of any of the Issuing Bank’s correspondents; and none of the above shall affect, impair or prevent the vesting of any of the Issuing Bank’s, the Agent’s or any Lender’s rights or powers hereunder under the Letter of Credit Agreements, all of which rights shall be cumulative. The 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, the Borrower agrees that any action, inaction or omission taken or not taken by the Issuing Bank or by any correspondent for the Issuing Bank in good faith in connection with any Letter of Credit, or any related drafts, certificates, documents or instruments, shall be binding on the Borrower and shall not put the Issuing Bank or its correspondents under any resulting liability to the Borrower.

Section 2.10 Obligation to Reimburse and to Prepay.

(a) If a disbursement by the Issuing Bank is made under any Letter of Credit, the Borrower shall pay to the Issuing Bank ON DEMAND but in no event later than two (2) Business Days after notice of any such disbursement is received by the Borrower, the amount of each such disbursement made by the 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 the 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 the 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 the 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), the Issuing Bank, the 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 the 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; and (vi) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing.

Notwithstanding anything in this Agreement to the contrary, the Borrower will not be liable for payment or performance that results from the gross negligence or willful misconduct of the Issuing Bank, except where the Borrower or any Subsidiary actually recovers the proceeds for itself or the Issuing Bank of any payment made by the Issuing Bank in connection with such gross negligence or willful misconduct.

(b) 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 the LC Exposure (or the excess in the case of Section 2.07(b)) shall be deemed to be forthwith due and owing by the Borrower to the Agent as of the date of any such occurrence; and the Borrower’s obligation to pay such amount shall be absolute and unconditional, without regard to whether any beneficiary of any such Letter of Credit has attempted to draw down all or a portion of such amount under the terms of a Letter of Credit, and, to the fullest extent permitted by applicable law, shall not be subject to any defense or be affected by a right of set-off, counterclaim or recoupment which the Borrower may now or hereafter have against any such beneficiary, the Issuing Bank, the Agent, the Lenders or any other Person for any reason whatsoever. Such payments shall be held by the Agent on behalf of the Lenders as cash collateral securing the LC Exposure in an interest-bearing account or accounts (such interest being for the account of the Borrower, but must remain pledged as security in favor of the Agent on behalf of the Lenders) at the Principal Office; and the Borrower hereby grants to and by its deposit with the Agent grants to the Agent a security interest in such cash collateral. Upon request by the Agent, the Borrower shall immediately execute and deliver to the Agent the Cash Collateral Account Agreement. In the event of any such payment by the 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, the 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 the Security Instruments, to remit to the Borrower amounts for which the contingent obligations evidenced by the Letters of Credit have ceased.

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

(d) Notwithstanding anything to the contrary contained herein, if no Default exists and subject to availability under the Aggregate Revolving Credit Commitments (after reduction for LC Exposure), to the extent the Borrower has not reimbursed the Issuing Bank for any drawn upon Letter of Credit within two (2) Business Day after notice of such disbursement has been received by the 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 has occurred and is continuing, or if the funding of such Letter of Credit reimbursement obligation as a Loan would cause the aggregate amount of all Loans outstanding to exceed the Aggregate Revolving Credit Commitments (after reduction for LC Exposure), 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.

Section 2.12 Termination of Hedging Agreement. If and to the extent any Hedging Agreement or similar price protection or derivative product (interest rate or commodity risk management device, protection agreement or otherwise) pursuant to Hedging Transactions of the Borrower is used in calculation of the Borrowing Base, such Hedging Agreement issued cannot be cancelled, liquidated or “unwound” thereby without the prior written consent of the Required Lenders and the Agent.

Section 2.13 Lender/Agent Non-liability to Royalty Owners/Third Parties. Nothing in this Agreement or in the other Loan Documents is intended to affect in any way the manner in which the Borrower performs or complies with its contractual obligations under oil and gas leases or other applicable contracts. In the event that the manner in which the Borrower markets production does not satisfy the duties owing by the Borrower to royalty owners or other parties under applicable law or contract, the Borrower covenants and agrees that it will pay any such additional sums as may be required under applicable law or contract to satisfy its obligations to such royalty owners and to such third parties.

Section 2.14 MCR. As of the first (1^st) day of each calendar month, commencing May 1, 2006, the amount available under the Revolving Credit Commitments shall be automatically reduced by the then applicable monthly commitment reduction (“MCR”) amount as determined by the Required Lenders. To the extent the sum of (i) the outstanding principal balance of the Notes plus (ii) the LC Exposure is in excess of the adjusted amount of the Aggregate Revolving Credit Commitment Amounts, the Borrower shall make a mandatory principal prepayment on the Notes in such amount as is necessary to reduce the sum of (i) the outstanding principal balance of the Notes plus (ii) the LC Exposure to an amount less than or equal to the adjusted Revolving Credit Commitments, which such mandatory principle prepayment shall be made within five (5) days of the applicable MCR application. The amount of the MCR (initially stipulated to be zero dollars ($0)) shall be evaluated and redetermined by the Required Lenders concurrent with each semi-annual Borrowing Base redetermination in accordance with the provisions of Section 2.08.

(a) Interest Rates. Except as otherwise provided in Section 3.02(b), the Borrower will pay to the 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 required to be a Base Rate Loan, the Base Rate (as in effect from time to time), but in no event to exceed the Highest Lawful Rate; and

(ii) if such a Loan is a LIBOR Loan, for each Interest Period relating thereto, the LIBOR Rate plus the LIBOR Margin for such LIBOR Loan 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 the Borrower under this Agreement, the Notes and the Letter of Credit Agreements shall be made in Dollars, in immediately available funds, to the Agent at such account as the Agent shall specify by notice to the Borrower from time to time, not later than 11:00 a.m. Tulsa, Oklahoma 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. Each payment received by the 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 the Agent of any principal of or interest on any borrowing, the Borrower shall notify the Agent of the Loans to which such payment shall apply. In the absence of such notice the 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 commitment fee or other fees under Section 2.04 shall be made for account of the Agent or the Lenders pro rata (as applicable) in accordance with their Percentage Share, and each reduction of the amount of the Aggregate Maximum Revolving Credit Amounts under Section 2.03(b) shall be applied to the Revolving Credit Commitment of each Lender, pro rata according to the amount of its respective Revolving Credit Commitment; (ii) each payment of principal of Loans by the Borrower shall be made for account of the Lenders pro rata in accordance with their respective Percentage Shares; and (iii) each payment of interest on Loans by the Borrower shall be made for account of the Lenders pro rata in accordance with their respective Percentage Shares; and (iv) each reimbursement by the Borrower of disbursements under Letters of Credit shall be made for account of the Issuing Bank or, if funded by the Lenders, pro rata for the account of the Lenders, in accordance with their respective Percentage Shares.

Section 4.03 Computations. Interest on Loans and fees shall be computed on the basis of a year of three hundred sixty (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 three hundred sixty five (365) days.

Section 4.04 Non-receipt of Funds by the Agent. Unless the Agent shall have been notified by a Lender or the Borrower prior to the date on which such notifying party is scheduled to make payment to the Agent (in the case of a Lender) of the proceeds of a Loan or a payment under a Letter of Credit to be made by it hereunder or (in the case of the Borrower) a payment to the Agent for account of one or more of the Lenders hereunder (such payment being herein called the “Required Payment”), which notice shall be effective upon receipt, that it does not intend to make the Required Payment to the Agent, the Agent may assume that the Required Payment has been made and may, in reliance upon such assumption (but shall not be required to), make the amount thereof available to the intended recipient(s) on such date and, if such Lender or the Borrower (as the case may be) has not in fact made the Required Payment to the Agent, the recipient(s) of such payment shall, on demand, repay to the Agent the amount so made available together with interest thereon in respect of each day during the period commencing on the date such amount was so made available by the Agent until, but excluding, the date the Agent recovers such amount at a rate per annum which, for any Lender as recipient, will be equal to the Federal Funds Rate, and for the Borrower as recipient, will be equal to the Base Rate.

Section 4.05 Set-off, Sharing of Payments.

(a) The Borrower agrees that, in addition to (and without limitation of) any right of set-off, bankers’ lien or counterclaim a Lender may otherwise have, each Lender shall have the right and be entitled (after consultation with the Agent), at its option, to offset balances held by it or by any of its Affiliates for account of the Borrower [or any Subsidiary] at any of its offices, in Dollars or in any other currency, against any principal of or interest on any of such Lender’s Loans, or any other amount payable to such Lender hereunder, which is not paid when due (regardless of whether such balances are then due to the Borrower), in which case it shall promptly notify the Borrower and the Agent thereof, provided that such Lender’s failure to give such notice shall not affect the validity thereof.

(b) If any Lender shall obtain payment of any principal of or interest on any Loan made by it to the Borrower under this Agreement (or reimbursement as to any Letter of Credit) through the exercise of any right of set-off, banker’s lien or counterclaim or similar right or otherwise, and, as a result of such payment, such Lender shall have received a greater percentage of the principal or interest (or reimbursement) then due hereunder by the Borrower to such Lender than the percentage received by any other Lenders, it shall promptly (i) notify the Agent and each other Lender thereof and (ii) purchase from such other Lenders participations in (or, if and to the extent specified by such Lender, direct interests in) the Loans (or participations in Letters of Credit) made by such other Lenders (or in interest due thereon, as the case may be) in such amounts, and make such other adjustments from time to time as shall be equitable, to the end that all the Lenders shall share the benefit of such excess payment (net of any expenses which may be incurred by such Lender in obtaining or preserving such excess payment) pro rata in accordance with the unpaid principal and/or interest on the Loans held by each of the Lenders (or reimbursements of Letters of Credit). To such end all the Lenders shall make appropriate adjustments among themselves (by the resale of participations sold or otherwise) if such payment is rescinded or must otherwise be restored. The Borrower agrees that any Lender so purchasing a participation (or direct interest) in the Loans made by other Lenders (or in interest due thereon, as the case may be) may exercise all rights of set-off, banker’s lien, counterclaim or similar rights with respect to such participation as fully as if such Lender were a direct holder of Loans (or Letters of Credit) in the amount of such participation. Nothing contained herein shall require any Lender to exercise any such right or shall affect the right of any Lender to exercise, and retain the benefits of exercising, any such right with respect to any other indebtedness or obligation of the Borrower. 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) Payments Free and Clear. Any and all payments by the Borrower hereunder shall be made, in accordance with Section 4.01, free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of each Lender, the Issuing Bank and the Agent, taxes imposed on its income, and franchise or similar taxes imposed on it, by (i) any jurisdiction (or political subdivision thereof) of which the Agent, the Issuing Bank or such Lender, as the case may be, is a citizen or resident or in which such Lender has an Applicable Lending Office, (ii) the jurisdiction (or any political subdivision thereof) in which the Agent, the Issuing Bank or such Lender is organized, or (iii) any jurisdiction (or political subdivision thereof) in which such Lender, the Issuing Bank or the Agent is presently doing business which taxes are imposed solely as a result of doing business in such jurisdiction (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as “Taxes”). If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder to the Lenders, the Issuing Bank or the Agent (i) the sum payable shall be increased by the amount necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 4.06) such Lender, the Issuing Bank or the Agent (as the case may be) shall receive an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant taxing authority or other Governmental Authority in accordance with applicable law.

(b) Other Taxes. In addition, to the fullest extent permitted by applicable law, the Borrower agrees to pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies that arise from any payment made hereunder or from the execution, delivery or registration of, or otherwise with respect to, this Agreement, any Assignment or any Security Instrument (hereinafter referred to as “Other Taxes”).

(C) INDEMNIFICATION. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE BORROWER WILL INDEMNIFY EACH LENDER AND THE ISSUING BANK AND THE AGENT FOR THE FULL AMOUNT OF TAXES AND OTHER TAXES (INCLUDING, BUT NOT LIMITED TO, ANY TAXES OR OTHER TAXES IMPOSED BY ANY GOVERNMENTAL AUTHORITY ON AMOUNTS PAYABLE UNDER THIS SECTION 4.06) PAID BY SUCH LENDER, THE ISSUING BANK OR THE AGENT (ON THEIR BEHALF OR ON BEHALF OF ANY LENDER), AS THE CASE MAY BE, AND ANY LIABILITY (INCLUDING PENALTIES, INTEREST AND EXPENSES) ARISING THEREFROM OR WITH RESPECT THERETO, WHETHER OR NOT SUCH TAXES OR OTHER TAXES WERE CORRECTLY OR LEGALLY ASSERTED UNLESS THE PAYMENT OF SUCH TAXES WAS NOT CORRECTLY OR LEGALLY ASSERTED AND SUCH LENDER’S PAYMENT OF SUCH TAXES OR OTHER TAXES WAS THE RESULT OF ITS GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. ANY PAYMENT PURSUANT TO SUCH INDEMNIFICATION SHALL BE MADE WITHIN THIRTY (30) DAYS AFTER THE DATE ANY LENDER, THE ISSUING BANK OR THE AGENT, AS THE CASE MAY BE, MAKES WRITTEN DEMAND THEREFOR. IF ANY LENDER, THE ISSUING BANK OR THE AGENT RECEIVES A REFUND OR CREDIT IN RESPECT OF ANY TAXES OR OTHER TAXES FOR WHICH SUCH LENDER, ISSUING BANK OR THE AGENT HAS RECEIVED PAYMENT FROM THE BORROWER IT SHALL PROMPTLY NOTIFY THE BORROWER OF SUCH REFUND OR CREDIT AND SHALL, IF NO DEFAULT HAS OCCURRED AND IS CONTINUING, WITHIN THIRTY (30) DAYS AFTER RECEIPT OF A REQUEST BY THE BORROWER (OR PROMPTLY UPON RECEIPT, IF THE BORROWER HAS REQUESTED APPLICATION FOR SUCH REFUND OR CREDIT PURSUANT HERETO), PAY AN AMOUNT EQUAL TO SUCH REFUND OR CREDIT TO THE BORROWER WITHOUT INTEREST (BUT WITH ANY INTEREST SO REFUNDED OR CREDITED), PROVIDED THAT THE BORROWER, UPON THE REQUEST OF SUCH LENDER, THE ISSUING BANK OR THE AGENT, AGREES TO RETURN SUCH REFUND OR CREDIT (PLUS PENALTIES, INTEREST OR OTHER CHARGES) TO SUCH LENDER OR THE AGENT IN THE EVENT SUCH LENDER OR THE AGENT IS REQUIRED TO REPAY SUCH REFUND OR CREDIT.

(d) Lender Representations.

(i) Each Lender represents that it is either (1) a banking association or corporation organized under the laws of the United States of America or any state thereof or (2) it is entitled to complete exemption from United States withholding tax imposed on or with respect to any payments, including fees, to be made to it pursuant to this Agreement (A) under an applicable provision of a tax convention to which the United States of America is a party or (B) because it is acting through a branch, agency or office in the United States of America and any payment to be received by it hereunder is effectively connected with a trade or business in the United States of America. Each Lender that is not a banking association or corporation organized under the laws of the United States of America or any state thereof agrees to provide to the Borrower and the Agent on the Closing Date, or on the date of its delivery of the Assignment pursuant to which it becomes a Lender, and at such other times as required by United States law or as the Borrower or the Agent shall reasonably request, two accurate and complete original signed copies of either (A) Internal Revenue Service Form W-8ECI (or successor form) certifying that all payments to be made to it hereunder will be effectively connected to a United States trade or business (the “Form W-8ECI Certification”) or (B) Internal Revenue Service Form W-8BEN (or successor form) certifying that it is entitled to the benefit of a provision of a tax convention to which the United States of America is a party which completely exempts from United States withholding tax all payments to be made to it hereunder (the “Form W-8BEN Certification”). In addition, each Lender agrees that if it previously filed a Form W-8ECI Certification, it will deliver to the Borrower and the Agent a new Form W-8ECI Certification prior to the first payment date occurring in each of its subsequent taxable years; and if it previously filed a Form W-8BEN Certification, it will deliver to the Borrower and the Agent a new certification prior to the first payment date falling in the third year following the previous filing of such certification. Each Lender also agrees to deliver to the Borrower and the Agent such other or supplemental forms as may at any time be required as a result of changes in applicable law or regulation in order to confirm or maintain in effect its entitlement to exemption from United States withholding tax on any payments hereunder, provided that the circumstances of such Lender at the relevant time and applicable laws permit it to do so. If a Lender determines, as a result of any change in either (i) a Governmental Requirement or (ii) its circumstances, that it is unable to submit any form or certificate that it is obligated to submit pursuant to this Section 4.06, or that it is required to withdraw or cancel any such form or certificate previously submitted, it shall promptly notify the Borrower and the Agent of such fact. If a Lender is organized under the laws of a jurisdiction outside the United States of America, unless the Borrower and the Agent have received a Form W-8BEN Certification or Form W-8ECI Certification satisfactory to them indicating that all payments to be made to such Lender hereunder are not subject to United States withholding tax, the Borrower shall withhold taxes from such payments at the applicable statutory rate. Each Lender agrees to indemnify and hold harmless the Borrower or Agent, as applicable, from any United States taxes, penalties, interest and other expenses, costs and losses incurred or payable by (i) the Agent as a result of such Lender’s failure to submit any form or certificate that it is required to provide pursuant to this Section 4.06 or (ii) the Borrower or the Agent as a result of their reliance on any such form or certificate which such Lender has provided to them pursuant to this Section 4.06.

(ii) For any period with respect to which a Lender has failed to provide the Borrower with the form required pursuant to this Section 4.06, if any, (other than if such failure is due to a change in a Governmental Requirement occurring subsequent to the date on which a form originally was required to be provided), such Lender shall not be entitled to indemnification under Section 4.06 with respect to taxes imposed by the United States which taxes would not have been imposed but for such failure to provide such forms; provided, however, that if a Lender, which is otherwise exempt from or subject to a reduced rate of withholding tax, becomes subject to taxes because of its failure to deliver a form required hereunder, the Borrower shall take such steps as such Lender shall reasonably request to assist such Lender to recover such taxes.

(iii) Any Lender claiming any additional amounts payable pursuant to this Section 4.06 shall use reasonable efforts (consistent with legal and regulatory restrictions) to file any certificate or document requested by the Borrower or the Agent or to change the jurisdiction of its Applicable Lending Office or to contest any tax imposed if the making of such a filing or change or contesting such tax would avoid the need for or reduce the amount of any such additional amounts that may thereafter accrue and would not, in the sole determination of such Lender, be otherwise disadvantageous to such Lender.

Section 4.07 Disposition of Proceeds. The Mortgages contain an assignment by the Borrower unto and in favor of the Agent for the benefit of the Lenders of all production and all proceeds attributable thereto which may be produced from or allocated to the Mortgaged Property, and the Mortgages further provide in general for the application of such proceeds to the satisfaction of the Obligations and other indebtedness, liabilities and obligations described therein and secured thereby. Notwithstanding the assignment contained in the Mortgages, until the occurrence of a Default, the Lenders agree that they will neither notify the purchaser or purchasers of such production nor take any other action to cause such proceeds to be remitted to the Lenders, but the Lenders will instead permit such proceeds to be paid to the Borrower.

ARTICLE V

CAPITAL ADEQUACY AND ADDITIONAL COSTS

Section 5.01 Capital Adequacy and Additional Costs.

(a) Lender Costs. The Borrower shall pay directly to each Lender from time to time on request such amounts as such Lender may determine to be necessary to compensate such Lender or its parent or holding company for any costs which it determines are attributable to the maintenance by such Lender or its parent or holding company, pursuant to any Governmental Requirement, of capital in respect of its Revolving Credit Commitment or making, funding or maintaining any Loans or Letters of Credit (such compensation to include, without limitation, an amount equal to any reduction of the rate of return on assets or equity of such Lender or its parent or holding company to a level below that which such Lender or its parent or holding company could have achieved but for such Governmental Requirement). Each Lender will notify the Borrower that it is entitled to compensation pursuant to this Section 5.01(a) as promptly as practicable after it determines to request such compensation.

(b) Conclusions. Determinations and allocations by any Lender for purposes of this Article V shall be conclusive, provided that such determinations and allocations are made on a reasonable basis.

(c) LIBOR Regulations. The Borrower shall pay directly to each Lender from time to time such amounts as such Lender may determine to be necessary to compensate such Lender for any costs which it determines are attributable to its making or maintaining of any LIBOR Loans or issuing or participating in Letters of Credit hereunder or its obligation to make any LIBOR Loans or issue or participate in any Letters of Credit hereunder, or any reduction in any amount receivable by such Lender hereunder in respect of any of such LIBOR Loans, Letters of Credit or such obligation (such increases in costs and reductions in amounts receivable being herein called “Additional Costs”), resulting from any Regulatory Change which: (i) changes the basis of taxation of any amounts payable to such Lender under this Agreement or any Note in respect of any of such LIBOR Loans or Letters of Credit (other than taxes imposed on the overall net income of such Lender or of its Applicable Lending Office for any of such LIBOR Loans by the jurisdiction in which such Lender has its principal office or Applicable Lending Office); or (ii) imposes or modifies any reserve, special deposit, minimum capital, capital ratio or similar requirements relating to any extensions of credit or other assets of, or any deposits with or other liabilities of such Lender, or the Revolving Credit Commitment or Loans of such Lender or the LIBOR interbank market; or (iii) imposes any other condition affecting this Agreement or any Note (or any of such extensions of credit or liabilities) or such Lender’s Revolving Credit Commitment or Loans. Each Lender will notify the Agent and the Borrower of any event occurring after the Closing Date which will entitle such Lender to compensation pursuant to this Section 5.01(c) as promptly as practicable after it obtains knowledge thereof and determines to request such compensation, and will designate a different Applicable Lending Office for the Loans of such Lender affected by such event if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the sole opinion of such Lender, be disadvantageous to such Lender, provided that such Lender shall have no obligation to so designate an Applicable Lending Office located in the United States. If any Lender requests compensation from the Borrower under this Section 5.01(c), the 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).

(d) Regulatory Change. Without limiting the effect of the provisions of Section 5.01(c), in the event that at any time (by reason of any Regulatory Change or any other circumstances arising after the Closing Date affecting (A) any Lender, (B) the LIBOR interbank market or (C) such Lender’s position in such market), the LIBOR Rate, as determined in good faith by such Lender, will not adequately and fairly reflect the cost to such Lender of funding its LIBOR Loans, then, if such Lender so elects, by notice to the Borrower and the Agent, the obligation of such Lender to make additional LIBOR Loans shall be suspended until such Regulatory Change or other circumstances ceases to be in effect (in which case the provisions of Section 5.04 shall be applicable).

(e) Capital Adequacy. Without limiting the effect of the foregoing provisions of this Section 5.01 (but without duplication), the Borrower shall pay directly to any Lender from time to time on request such amounts as such Lender may reasonably determine to be necessary to compensate such Lender or its parent or holding company for any costs which it determines are attributable to the maintenance by such Lender or its parent or holding company (or any Applicable Lending Office), pursuant to any Governmental Requirement following any Regulatory Change, of capital in respect of its Revolving Credit Commitment, its Note, or its Loans or any interest held by it in any Letter of Credit, such compensation to include, without limitation, an amount equal to any reduction of the rate of return on assets or equity of such Lender or its parent or holding company (or any Applicable Lending Office) to a level below that which such Lender or its parent or holding company (or any Applicable Lending Office) could have achieved but for such Governmental Requirement. Such Lender will notify the Borrower that it is entitled to compensation pursuant to this Section 5.01(e) as promptly as practicable after it determines to request such compensation.

(f) Compensation Procedure. Any Lender notifying the Borrower of the incurrence of Additional Costs under this Section 5.01 shall in such notice to the Borrower and the Agent set forth in reasonable detail the basis and amount of its request for compensation. Determinations and allocations by each Lender for purposes of this Section 5.01 of the effect of any Regulatory Change pursuant to Section 5.01(c) or (d), or of the effect of capital maintained pursuant to Section 5.01(e), on its costs or rate of return of maintaining Loans or its obligation to make Loans or issue Letters of Credit, or on amounts receivable by it in respect of Loans or Letters of Credit, and of the amounts required to compensate such Lender under this Section 5.01, shall be conclusive and binding for all purposes, provided that such determinations and allocations are made on a reasonable basis. Any request for additional compensation under this Section 5.01 shall be paid by the Borrower within thirty (30) days of the receipt by the Borrower of the notice described in this Section 5.01(f).

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

(i) the 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 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

(ii) the Agent determines (which determination shall be conclusive, absent manifest error) that the relevant rates of interest referred to in the definition of “LIBOR 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 the Agent shall give the Borrower prompt notice thereof, and so long as such condition remains in effect, the Lenders shall be under no obligation to make additional or other 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 the 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 or Section 5.03 has occurred and such Lender so requests by notice to the 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, if any. Notwithstanding any other terms or provisions of this Agreement or the Notes, the Borrower, the Lenders and the Agent stipulate, acknowledge and agree that all Loans made hereunder and all interest calculations and accruals on the principal amounts outstanding from time to time on the Notes and on all other Obligations shall be made, continued and treated in all respects as LIBOR Loans except only as otherwise expressly provided in this Section 5.04.

Section 5.05 Compensation. The 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:

(i) any payment, prepayment or conversion of a LIBOR Loan properly made by such Lender or the Borrower for any reason (including, without limitation, the acceleration of the Loans pursuant to Article X) on a date other than the last day of the Interest Period for such Loan; or

(ii) any failure by the 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 breakage and other similar compensation shall include, in addition to such Lender’s standard breakage administration fee, 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 Replacement Lenders.

(a) If any Lender (i) has notified the Borrower and the Agent of its incurring Additional Costs under Section 5.01, (ii) has required the Borrower to make payments for Taxes under Section 4.06, (iii) defaults in its obligations to fund advances hereunder or participate in LC Exposure, or (iv) is a Non-Extending Lender pursuant to Section 5.07 then the Borrower may, at its sole cost, expense and effort, provided that no Event of Default then exists, unless such Lender has notified the Borrower and the Agent in writing that the circumstances giving rise to such notice, event or circumstance no longer apply or such Lender otherwise withdraws its request for such additional compensation, terminate, in whole but not in part, the Revolving Credit Commitment of any Lender (other than the Agent) (in any such case, the “Terminated Lender”) at any time within ninety (90) days of such Lender notification, upon thirty (30) days’ prior written notice to the Terminated Lender and the Agent (such notice referred to herein as a “Notice of Termination”).

(b) In order to effect the termination of the Revolving Credit Commitment of the Terminated Lender, the Borrower shall: (i) obtain an agreement with one or more Lenders to increase their Revolving Credit Commitment or Revolving Credit Commitments and/or (ii) request any one or more other banking or lending institutions to become parties to this Agreement in place and instead of such Terminated Lender and agree to accept a Revolving Credit Commitment or Revolving Credit Commitments; provided, however, that such one or more other banking or lending institutions are reasonably acceptable to the Agent and become parties by executing an Assignment (the Lenders or other banking institutions that agree to accept in whole or in part the Revolving Credit Commitment of the Terminated Lender being referred to herein as the “Replacement Lenders”) without recourse from the Terminated Lender, such that the aggregate increased and/or accepted Revolving Credit Commitments of the Replacement Lenders under clauses (i) and (ii) above equal the Revolving Credit Commitment of the Terminated Lender.

(c) The Notice of Termination shall include the name of the Terminated Lender, the date the termination will occur (the “Lender Termination Date”), and the Replacement Lender or Replacement Lenders to which the Terminated Lender will assign its Revolving Credit Commitment and, if there will be more than one Replacement Lender, the portion of the Terminated Lender’s Revolving Credit Commitment to be assigned to each Replacement Lender.

(d) On the Lender Termination Date, (i) the Terminated Lender shall by execution and delivery of an Assignment assign, without recourse, its Revolving Credit Commitment and all of its interests, rights and obligations under this Agreement and the related Loan Documents to the Replacement Lender or Replacement Lenders (pro rata, if there is more than one Replacement Lender, in proportion to the Percentage Share of the Terminated Lender’s Revolving Credit Commitment to be assigned to each Replacement Lender) indicated in the Notice of Termination and shall assign to the Replacement Lender or Replacement Lenders each of its Loans (if any) then outstanding and participation interests in Letters of Credit (if any) then outstanding pro rata as aforesaid), (ii) the Terminated Lender shall endorse its Note, payable without recourse, representation or warranty to the order of the Replacement Lender or Replacement Lenders (Percentage Share as aforesaid), (iii) the Replacement Lender or Replacement Lenders shall purchase the Note held by the Terminated Lender (pro rata as aforesaid) at a price equal to the unpaid principal amount thereof (including its participation in and Percentage Share of the LC Exposure) plus interest, facility fees, Revolving Credit Commitment Fees and other fees accrued and unpaid to the Lender Termination Date, and (iv) the Replacement Lender or Replacement Lenders will thereupon (pro rata as aforesaid) succeed to and be substituted in all respects for the Terminated Lender with like effect as if becoming a Lender pursuant to the terms of Section 12.06(b), and the Terminated Lender will have the rights and benefits of an assignor under Section 12.06(b). To the extent not in conflict, the terms of Section 12.06(b) shall supplement the provisions of this Section 5.06(d). For each assignment made under this Section 5.06, the Replacement Lender shall pay to the Agent the processing fee provided for in Section 12.06(b). The Borrower will be responsible for the concurrent payment of any breakage costs associated with termination and Replacement Lenders, as set forth in Section 5.05.

The election of any Lender to agree to such extension shall not obligate any other Lender to so agree.

(c) Notification by Agent. The Agent shall notify the Borrower of each Lender’s determination under this Section no later than the date 30 days prior to the Existing Maturity Date (or, if such date is not a Business Day, on the next preceding Business Day).

Section 8.08 Title Information and Mortgage Coverage.

(a) Mortgage and Title Coverage. The Borrower will provide the Agent with (i) title information in form and substance reasonably acceptable to the Agent and (ii) Mortgages on the Oil and Gas Properties of the Borrower and its Subsidiaries, in form and substance satisfactory to Agent, and subject only to Excepted Liens, which are, at all times, sufficient to cause the value of the proved Oil and Gas Properties of the Borrower and its Subsidiaries that are covered both by such title information and by Mortgages in favor of the Agent for the benefit of the Lenders to satisfy the Eighty Percent Coverage Requirement..

(b) Cure of Title Defects. The Borrower shall promptly proceed in good faith to cure any title defects or exceptions which are not Excepted Liens raised by such title information, or substitute acceptable Oil and Gas Properties with no material title defects or exceptions except for Excepted Liens covering Oil and Gas Property sufficient to cause the Eighty Percent Coverage Requirement to be maintained, as promptly as reasonable, and in any event, within ninety (90) days after a request by the Agent or the Lenders to cure such defects or exceptions. With respect to this Section 8.08(b), “material title defects or exceptions” shall mean the defects and exceptions relating to all the Oil and Gas Properties that could reasonably be expected to materially affect the revenue stream attributable to such Oil and Gas Properties and the cost to cure such defects or exceptions could reasonably be expected to exceed $100,000 individually or $1,000,000 in the aggregate to cure.

(c) Failure to Cure Title Defects. If the Borrower is unable to cure any title defect requested by the Agent or the Lenders to be cured within the ninety (90)-day period or the Borrower does not substitute acceptable Oil and Gas Properties sufficient to cause the Eighty Percent Coverage Requirement to be maintained, such default shall not be a Default or an Event of Default, but instead the 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 the Agent or the Lenders. To the extent that the Agent or the Lenders are not satisfied with title to any such Oil and Gas Property after the time period in Section 8.08(b) has elapsed, such unacceptable Oil and Gas Property shall not count towards the Eighty Percent Coverage Requirement, and the Agent may send a notice to the Borrower and the Lenders that the then outstanding Borrowing Base shall be reduced by an amount as determined by the Lenders to cause the Borrower to be in compliance with the Eighty Percent Coverage Requirement as to the value of the Oil and Gas Properties. This new Borrowing Base shall become effective immediately after receipt of such notice.

Section 8.09 Additional Collateral.

(a) Lien on Acquired Oil and Gas Properties.

ARTICLE XI

THE AGENT

Section 11.01 Appointment, Powers and Immunities. Each Lender hereby irrevocably appoints and authorizes the Agent to act as its agent hereunder and under the Security Instruments with such powers as are specifically delegated to the Agent by the terms of this Agreement and the Security Instruments, together with such other powers as are reasonably incidental thereto. The Agent (which term as used in this sentence and in Section 11.05 and the first sentence of Section 11.06 shall include reference to its Affiliates and its and its Affiliates’ officers, directors, employees, attorneys, accountants, experts and agents): (i) shall have no duties or responsibilities except those expressly set forth in the Loan Documents, and shall not by reason of the Loan Documents be a trustee or fiduciary for any Lender; (ii) makes no representation or warranty to any Lender and shall not be responsible to the Lenders for any recitals, statements, representations or warranties contained in this Agreement, or in any certificate or other document referred to or provided for in, or received by any of them under, this Agreement, or for the value, validity, effectiveness, genuineness, execution, effectiveness, legality, enforceability or sufficiency of this Agreement, any Note or any other document referred to or provided for herein or for any failure by the Borrower or any other Person (other than the Agent) to perform any of its obligations hereunder or thereunder or for the existence, value, perfection or priority of any collateral security or the financial or other condition of the Borrower, its Subsidiaries or any other obligor or guarantor; (iii) except pursuant to Section 11.07 shall not be required to initiate or conduct any litigation or collection proceedings hereunder; and (iv) shall not be responsible for any action taken or omitted to be taken by it hereunder or under any other document or instrument referred to or provided for herein or in connection herewith including its own ordinary negligence, except for its own gross negligence or willful misconduct. The Agent may employ agents, accountants, attorneys and experts and shall not be responsible for the negligence or misconduct of any such agents, accountants, attorneys or experts selected by it in good faith or any action taken or omitted to be taken in good faith by it in accordance with the advice of such agents, accountants, attorneys or experts. The Agent may deem and treat the payee of any Note as the holder thereof for all purposes hereof unless and until a written notice of the assignment or transfer thereof permitted hereunder shall have been filed with the Agent. The 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. The Agent shall be entitled to rely upon any Note, certification, notice, consent, affidavit, letter, statement, paper, document or other communication (including any thereof by telephone, , courier, hand delivery, telex, telecopier, telegram or cable) believed by it to be genuine and correct and to have been signed or sent by or on behalf of the proper Person or Persons, and upon advice and statements of legal counsel, independent accountants and other experts selected by the Agent.

Section 11.03 Defaults. The Agent shall not be deemed to have knowledge of the occurrence of a Default (other than the non-payment of principal of or interest on Loans or of fees or failure to reimburse for Letter of Credit drawings) unless the Agent has received notice from a Lender or the Borrower specifying such Default and stating that such notice is a “Notice of Default.” In the event that the Agent receives such a notice of the occurrence of a Default, the Agent shall give prompt notice thereof to the Lenders. In the event of a payment Default, the Agent shall give each Lender prompt notice of each such payment Default.

Section 11.04 Rights as a Lender. With respect to its Revolving Credit Commitments and the Loans made by it and its participation in the issuance of Letters of Credit, MidFirst (and any successor acting as Agent) in its capacity as a Lender hereunder shall have the same rights and powers hereunder as any other Lender and may exercise the same as though it were not acting as the Agent, and the term “Lender” or “Lenders” shall, unless the context otherwise indicates, include the Agent in its individual capacity. MidFirst (and any successor acting as Agent) and its Affiliates may (without having to account therefore to any Lender) accept deposits from, lend money to and generally engage in any kind of banking, trust or other business with the Borrower (and any of its Affiliates) as if it were not acting as the Agent, and MidFirst and its Affiliates may accept fees and other consideration from the 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 THE AGENT AND THE 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 THE BORROWER UNDER SECTION 12.03, BUT WITHOUT LIMITING THE OBLIGATIONS OF THE 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 THE AGENT OR THE ISSUING BANK IN ANY WAY RELATING TO OR ARISING OUT OF: (I) THIS AGREEMENT, THE SECURITY INSTRUMENTS 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 SECURITY INSTRUMENT 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 THE AGENT OR THE 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 THE AGENT.

Section 11.06 Non-Reliance on Agent and other Lenders. Each Lender acknowledges and agrees that it has, independently and without reliance on the Agent or any other Lender, and based on such documents and information as it has deemed appropriate, made its own credit analysis of the Borrower and its decision to enter into this Agreement, and that it will, independently and without reliance upon the Agent or any other Lender, and based on such documents and information as it shall deem appropriate at the time, continue to make its own analysis and decisions in taking or not taking action under this Agreement. The Agent shall not be required to keep itself informed as to the performance or observance by the Borrower of this Agreement, the Notes, the Security Instruments or any other document referred to or provided for herein or to inspect the properties or books of the Borrower. Except for notices, reports and other documents and information expressly required to be furnished to the Lenders by the Agent hereunder, the 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 the Borrower (or any of its Affiliates) which may come into the possession of the Agent or any of its Affiliates. In this regard, each Lender acknowledges that ▇▇▇▇▇ & ▇▇▇▇▇▇▇ is acting in this transaction as special counsel to MidFirst, as a Lender, and as the Agent only, except to the extent otherwise expressly stated in any legal opinion or any Loan Document, and that such law firm does not represent any of the other Lenders in connection with this Agreement and the transactions contemplated hereby. 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. Except for action or other matters expressly required of the Agent hereunder, the Agent shall in all cases be fully justified in failing or refusing to act hereunder unless it shall (i) receive written instructions from the Required Lenders (or all of the Lenders as expressly required by Section 12.04) specifying the action to be taken, and (ii) be indemnified to its satisfaction by the Lenders against any and all liability and expenses which may be incurred by it by reason of taking or continuing to take any such action. The instructions of the Required Lenders (or all of the Lenders as expressly required by Section 12.04) and any action taken or failure to act pursuant thereto by the Agent shall be binding on all of the Lenders. If a Default has occurred and is continuing, the Agent shall take such action with respect to such Default as shall be directed by the Required 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 the Agent shall have received such directions, the Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default as it shall deem advisable in the best interests of the Lenders. In no event, however, shall the Agent be required to take any action which exposes the Agent to personal liability or which is contrary to this Agreement and the Security Instruments or applicable law.

Section 11.08 Resignation or Removal of Agent. Subject to the appointment and acceptance of a successor Agent as provided below, the Agent may resign at any time by giving notice thereof to the Lenders and the Borrower, and the Agent may be removed at any time with cause (excluding in such instance the vote of the Agent as a Lender) or without cause in writing by the Required Lenders (including the vote of the Agent in such instance). Upon any such resignation or removal, the Required Lenders shall have the right to appoint a successor Agent. If no successor Agent shall have been so appointed by the Required Lenders and shall have accepted such appointment within thirty (30) days after the retiring Agent’s giving of notice of resignation or the Required Lenders’ removal of the retiring Agent, then the retiring Agent may, on behalf of the Lenders, appoint a successor Agent. Upon the acceptance of such appointment hereunder by a successor Agent, such successor Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations hereunder. After any retiring Agent’s resignation or removal hereunder as Agent, the provisions of this Article XI and Section 12.03 shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was acting as the Agent.

Section 11.09 Execution of Security Instruments. The Lenders hereby empower and authorize the Agent to execute and deliver to the Borrower on their behalf the Security Instruments and all related financing statements and any financing statements, agreements, documents or instruments as shall be necessary or appropriate to effect the purposes of the Security Instruments.

ARTICLE XII

(a) The Borrower may not assign its rights or obligations hereunder or under the Notes or any Letters of Credit without the prior consent of all of the Lenders and the Agent.

(b) Any Lender may, upon the written consent of the Agent and, if no Event of Default has occurred and is continuing, the Borrower (which consent will not be unreasonably withheld), may assign to one or more assignees all or a portion of its rights and obligations under this Agreement pursuant to an Assignment Agreement substantially in the form of Exhibit D (an “Assignment”); provided, however, that (i) any such assignment shall be in the amount of at least $5,000,000.00 or such lesser amount to which the Borrower has consented and (ii) the assignee or assignor shall pay to the Agent a processing and recordation fee of $1,000.00 for each assignment. Any such assignment will become effective upon the execution and delivery to the Agent of the Assignment and the consent of the Agent. Promptly after receipt of an executed Assignment, the Agent shall send to the Borrower a copy of such executed Assignment. Upon receipt of such executed Assignment, the Borrower, will, at its own expense, execute and deliver new Notes to the assignor and/or assignee, as appropriate, in accordance with their respective interests as they appear. Upon the effectiveness of any assignment pursuant to this Section 12.06(b), the assignee will become a “Lender”, if not already a “Lender,” for all purposes of this Agreement and the Security Instruments. The assignor shall be relieved of its obligations hereunder to the extent of such assignment (and if the assigning Lender no longer holds any rights or obligations under this Agreement, such assigning Lender shall cease to be a “Lender” hereunder except that its rights under Sections 4.06, 5.01, 5.05 and 12.03 shall not be affected). The Agent will prepare on the last Business Day of each month during which an assignment has become effective pursuant to this Section 12.06(b), a new Annex I giving effect to all such assignments effected during such month, and will promptly provide the same to the Borrower and each of the Lenders.

(c) Each Lender may transfer, grant or assign participations in all or any part of such Lender’s interests hereunder pursuant to this Section 12.06(c) to any Person, provided that: (i) such Lender shall remain a “Lender” for all purposes of this Agreement and the transferee of such participation shall not constitute a “Lender” hereunder; and (ii) no participant under any such participation shall have rights to approve any amendment to or waiver of any of the Loan Documents except to the extent such amendment or waiver would (x) forgive any principal owing on any Obligations or extend the final maturity of the Loans, (y) reduce the interest rate (other than as a result of waiving the applicability of any post-default increases in interest rates) or fees applicable to any of the Revolving Credit Commitments or Loans or Letters of Credit in which such participant is participating, or postpone the payment of any thereof, or (z) release any guarantor of the Obligations or release all or substantially all of the collateral (except as provided in the Loan Documents) supporting any of the Revolving Credit Commitments or Loans or Letters of Credit in which such participant is participating. In the case of any such participation, the participant shall not have any rights under this Agreement or any of the Security Instruments (the participant’s rights against the granting Lender in respect of such participation to be those set forth in the agreement with such Lender creating such participation), and all amounts payable by the Borrower hereunder shall be determined as if such Lender had not sold such participation, provided that such participant shall be entitled to receive additional amounts under Article V on the same basis as if it were a Lender and be indemnified under Section 12.03 as if it were a Lender. In addition, each agreement creating any participation must include an agreement by the participant to be bound by the provisions of Section 12.15.

(d) The Lenders may furnish any information concerning the Borrower in the possession of the Lenders from time to time to assignees and participants (including prospective assignees and participants); provided that, such Persons agree to be bound by the provisions of Section 12.15.

(e) Notwithstanding anything in this Section 12.06 to the contrary, any Lender may assign and pledge its Note to any Federal Reserve Bank as collateral security pursuant to Regulation A of the Board of Governors of the Federal Reserve System and any operating circular issued by such Federal Reserve System and/or such Federal Reserve Bank. No such assignment and/or pledge shall release the assigning and/or pledging Lender from its obligations hereunder.

(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 the Borrower to file a registration statement with the SEC or to qualify the Loans under the “Blue Sky” laws of any state.

(g) Borrower acknowledges that the Initial Reserve Report will be furnished to all the Lenders and such Lenders must be satisfied, in each such Lenders’ sole discretion, that the Borrowing Base is valued at $65,000,000.00, and if not, such Lenders will not become one of the syndicated Lenders; and in connection therewith, if such other Lenders reasonably need additional engineering information, Borrower will provide same.

(h) This Agreement permits certain increases in a Lender’s Commitment and the admission of new or additional Lenders (“Additional Lenders”) providing new Commitments, none of which requires any consents or approvals from the other Lenders unless the Aggregate Maximum Revolving Credit Commitment Amount is increased above $150,000,000.00. Any amendment hereto for such an increase or addition shall be in the form attached hereto as Exhibit E and shall only require the written signatures of the Agent, the Borrower and the Additional Lender(s) being added or Lender(s) increasing its or their Maximum Revolving Credit Commitment(s). In addition, within a reasonable time after the effective date of any increase, the Agent shall, and is hereby authorized and directed to, revise Annex I reflecting such addition and/or increase and shall distribute such revised Annex I 1 to each of the Lenders and the Borrowers, whereupon such revised Annex I shall replace the old Annex I and become part of this Agreement. On the Business Day following any such addition and/or increase, all outstanding LC Exposure and Revolving Credit Loans shall be reallocated among the Lenders (including any Additional Lender(s)) in accordance with the Lenders’ respective revised Percentage Shares.

Section 12.07 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 12.14 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 Oklahoma 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 the Borrower); and (ii) in the event that the maturity of the Notes is accelerated by reason of an election of the holder thereof resulting from any Event of Default under this Agreement or otherwise, or in the event of any required or permitted prepayment, then such consideration that constitutes interest under law applicable to any Lender may never include more than the maximum amount allowed by such applicable law, and excess interest, if any, provided for in this Agreement or otherwise shall be canceled automatically by such Lender as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited by such Lender on the principal amount of the 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 the Borrower). All sums paid or agreed to be paid to any Lender for the use, forbearance or detention of sums due hereunder shall, to the extent permitted by law applicable to such Lender, be amortized, prorated, allocated and spread throughout the 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.

Section 12.15 Confidentiality. In the event that the Borrower provides to the Agent or the Lenders written confidential information belonging to the Borrower, if the Borrower shall denominate such information in writing as “confidential”, the 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 the Agent or the Lenders breaching their obligation of confidence to the Borrower, (iii) are previously known by the Agent or the Lenders from some source other than the Borrower, (iv) are hereafter developed by the Agent or the Lenders without using the Borrower’s information, (v) are hereafter obtained by or available to the Agent or the Lenders from a third party who owes no obligation of confidence to the Borrower with respect to such information or through any other means other than through disclosure by the Borrower, (vi) are disclosed with the Borrower’s consent, (vii) must be disclosed either pursuant to any Governmental Requirement or to Persons regulating the activities of the 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, the 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 Security Instrument, 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 the 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 the 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 the 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. The Borrower waives any and all other rights it may have to confidentiality as against the Agent and the Lenders arising by contract, agreement, statute or law except as expressly stated in this Section 12.15.

Section 12.16 Effectiveness. This Agreement shall be effective on the Closing Date (the "Effective Date").

Section 12.17 Exculpation Provisions. Each of the parties hereto specifically agrees that it has a duty to read this Agreement and the Security Instruments and agrees that it is charged with notice and knowledge of the terms of this Agreement and the Security Instruments; 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 Security Instruments; and has received the advice of its attorney in entering into this Agreement and the Security Instruments; and that it recognizes that certain of the terms of this Agreement and the Security Instruments 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 Security Instruments on the basis that the party had no notice or knowledge of such provision or that the provision is not “conspicuous.”

Section 12.18 Automatic Debit of Borrower’s Operating Account. Upon Borrower’s failure to pay all such costs and expenses owed by Borrowers under Section 12.03 of this Agreement within thirty (30) days of the Agent’s submission of invoices therefore, the Agent will pay such costs and expenses by debit to the operating account of Borrowers with the Agent without further or other notice to Borrower.

Section 12.19 Lost Documents. On receipt of an affidavit of an officer of the Agent as to the loss, theft, destruction or mutilation of the Notes or Security Instruments which is not of public record, and, in the case of any mutilation, on the surrender and cancellation of the Notes or Security Instruments, the Borrower or any Subsidiary Guarantors will issue, in lieu thereof, a replacement Note(s) or other Security Instruments in the same principal amount thereof (in the case of any of the Notes) and otherwise of like tenor.

Section 12.20 Syndication Agent. No Lender identified in this Agreement as the Syndication Agent will have any right, power, obligation, liability, responsibility or duty under this Agreement other than those applicable to all Lenders as such. Without limiting the foregoing, no Lender will have or be deemed to have a fiduciary relationship with any other Lender. Each Lender hereby makes the same acknowledgments with respect to such Lenders as it makes with respect to the Agent in Article XI.

Section 12.21 Restatement. This Agreement amends and restates the Existing Credit Agreement in its entirety. Borrower hereby agrees that (a) the indebtedness outstanding under the Existing Credit Agreement and the Loan Documents and Security Instruments (as defined in the Existing Credit Agreement; together with the Existing Credit Agreement, the “Existing Credit Documents”) and all accrued and unpaid interest thereon and (b) all accrued and unpaid fees under the Existing Credit Documents shall be deemed to be outstanding under and governed by this Agreement. Borrower hereby acknowledges, warrants, represents, and agrees that this Agreement is not intended to be, and shall not be deemed or construed to be, a novation or release of the Existing Credit Documents. Each Lender (which is a Lender under the Existing Credit Documents) hereby waives any requirements for notice of prepayment, minimum amounts of prepayments of the loans thereunder, ratable reductions of the commitments of Lenders under the Existing Credit Documents and ratable payments on account of the principal or interest of any loan under the Existing Credit Documents to the extent that any such prepayment, reductions or payments are required to ensure that, upon the effectiveness of this Agreement, the loans of the Lenders shall be outstanding on a ratable basis in accordance with their respective Percentage Share. Each Lender hereby authorizes Agent and Borrower to request borrowing advances from Lenders, to make prepayment of the loans under the Existing Credit Documents and to reduce the commitments under the Existing Credit Documents among Lenders in order to ensure that, upon the effectiveness of this Agreement, the loans of Lenders shall be outstanding on a ratable basis in accordance with their respective Percentage Share.

Section 12.22 Set off. In addition to, and without limitation of, any rights of the Lenders under applicable law, if Borrower, Guarantor or any Material Subsidiary becomes insolvent, however evidenced, or any Default occurs, any and all deposits (including all account balances, whether provisional or final and whether or not collected or available) and any other indebtedness at any time held or owing by any Lender or any Affiliate of any Lender to or for the credit or account of Borrower, Guarantor or any Material Subsidiary may be offset and applied toward the payment of the Obligations owing to such Lender, whether or not the Obligations, or any party thereof, shall be due.

Section 12.23 Ratable Payments. If any Lender, whether by setoff or otherwise, has payment made to it upon its Loans (other than payments received pursuant to Section 5.01 or 5.05) in a greater proportion than that received by any other Lender, such Lender agrees, promptly upon demand, to purchase a portion of the Loans held by the other Lenders so that after such purchase each Lender will hold its ratable proportion of Loans. If any Lender, whether in connection with setoff or amounts which might be subject to setoff or otherwise, receives collateral or other protection for its Obligations or such amounts which may be subject to setoff, such Lender agrees, promptly upon demand, to take such action necessary such that all Lenders share in the benefits of such collateral ratably in proportion to their Loans. In case any such payment is disturbed by legal process, or otherwise, appropriate further adjustments shall be made.

Section 12.24 Special New Mexico Indemnity Provisions. The parties reaffirm their intent that this Agreement be governed by the laws of the State of Oklahoma except the procedural or remedial laws of the state in which the Mortgaged Property is situated are to apply, without giving effect to the situs state’s principles of conflicts of law. Nevertheless, notwithstanding any other term or condition of this Agreement, to the extent, if at all, that (A) any provision requiring one party to indemnify, hold harmless, insure, or defend another party (including such other party’s agents or employees) contained herein or in any related Loan Document is found to be within the scope of NMSA (1978), § 56-7-1 (2003) or in any way subject to, or conditioned upon consistency with, the provisions of NMSA (1978), § 56-7-1 (2003), for its enforceability, then such provision, regardless of whether it makes reference to this or any other limitation provision, shall not extend to liability, claims, damages, losses or expenses, including attorney fees, arising out of bodily injury to persons or damage to property caused by or resulting from, in whole or in part, the negligence, act or omission of the indemnitee or additional insured, as the case may be, its officers, employees or agents, and shall be further modified, if required, by provisions of NMSA (1978), § 56-7-1 (B) (2003), or (B) NMSA (1978), § 56-7-2 (2003), as amended from time to time, is applicable to any agreement, covenant, or promise to indemnify another party, including such party’s employees or agents, contained herein or in any related Loan Document, such agreement does not purport to indemnify such indemnitee against loss or liability for damages arising from: (i) the sole or concurrent negligence of such indemnitee or the agents or employees of such indemnitee; (ii) the sole or concurrent negligence of an independent contractor who is directly responsible to such indemnitee; or (iii) an accident that occurs in operations carried on at the direction or under the supervision of such indemnitee, an employee or representative of such indemnitee or in accordance with methods and means specified by such indemnitee or the employees or representatives of such indemnitee.

Section 12.25 USA PATRIOT Act Notice. IMPORTANT INFORMATION ABOUT PROCEDURES FOR OPENING A NEW ACCOUNT. To help the government fight the funding of terrorism and money laundering activities, federal law requires all financial institutions to obtain, verify, and record information that identifies each person or entity that opens an account, including any deposit account, treasury management account, loan, other extension of credit, or other financial services product. What this means for Borrower: When a borrower opens an account, the Lenders will ask for the borrower’s name, residential address, tax identification number, and other information that will allow the Lenders to identify the borrower, including the borrower’s date of birth if the borrower is an individual. The Lenders may also ask, if the borrower is an individual, to see the borrower’s driver’s license or other identifying documents, and, if the borrower is not an individual, to see the borrower’s legal organizational documents or other identifying documents. The Lenders will verify and record the information the Lenders obtain from the Borrower pursuant to the USA PATRIOT Act, and will maintain and retain that record in accordance with the regulations promulgated under the USA PATRIOT Act.

Section 12.26 Not a Reportable Transaction. The parties signatory hereto acknowledge and stipulate and the Borrower represents to the Administrative Agent and the Lenders that the transactions contemplated by this Agreement do not constitute a “Reportable Event” as that term is described and defined in regulations of the Treasury Department of the United States.

FORM OF SUBSIDIARY GUARANTY

THIS GUARANTY AGREEMENT (“Guaranty”) is made and entered into effective as of May 3, 2006, by the undersigned guarantor (the “Guarantor”), in favor of (i) the Lenders from time to time parties to the Credit Agreement described below and (ii) MidFirst Bank, as Administrative Agent for the Lenders under the Credit Agreement.

RECITALS

A. Arena Resources, Inc., a Nevada corporation (the “Borrower”), the Lenders therein named, and MidFirst Bank, as Administrative Agent for the Lenders, are parties to that certain First Amended and Restated Credit Agreement dated effective as of even date herewith (as amended, modified, supplemented, restated and in effect from time to time, the “Credit Agreement”).

B. Capitalized terms used herein and not otherwise defined herein have the respective meanings assigned to them in the Credit Agreement.

C. Pursuant to the Credit Agreement, the Lenders have severally agreed to establish in favor of the Borrower certain Commitments for loan advances and an LC Exposure sub-limit resulting from the issuance of standby letters of credit for the account of the Borrower and/or its subsidiaries in the Aggregate Maximum Revolving Credit Commitment Amounts, subject to the Maximum Revolving Credit Amount available under the Credit Agreement from time to time in accordance with its terms, provisions, limitations and conditions.

D. The Guarantor is a Material Subsidiary and will receive substantial and valuable consideration and benefit from the Commitments and the Loans advanced and the LCs issued from time to time by the Lenders and the LC Issuer, respectively, to the Borrower pursuant to the Credit Agreement.

E. It is a condition precedent to the closing of the Credit Agreement and to each extension of credit thereunder that the Guarantor executes and delivers this Guaranty whereby the Guarantor shall absolutely and unconditionally guarantee the prompt and punctual payment when due of all of the Guaranteed Obligations (as hereinafter defined).

NOW, THEREFORE, in consideration of the credit to be extended pursuant to the Credit Agreement, and as a material inducement therefor, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Guarantor hereby covenants and agrees as follows:

SECTION 1. Guaranty. Subject only to Section 9 hereof, the Guarantor hereby guarantees to the Lenders and the Administrative Agent, absolutely, unconditionally and irrevocably, and without limitation as to amount, the full and prompt performance and payment when due (whether at a stated maturity or earlier by reason of acceleration or otherwise) of all Loans, LC Exposure and all other Obligations (as each such term is defined in the Credit Agreement), including, without limitation, principal, interest and fees, and all other liabilities and obligations now or hereafter owing by the Borrower to the Lenders under the Credit Agreement, the Notes and other relevant Loan Documents, including, without limitation, indemnities, reasonable attorneys’ fees, filing and recording costs, out-of-pocket expenses, collection costs and other amounts payable under the Loan Documents, including any such liabilities, indebtedness or obligations incurred or accrued during the pendency of any bankruptcy, insolvency, receivership or other similar proceeding, whether or not allowed or allowable in such proceeding (all of the foregoing liabilities and obligations being hereinafter collectively referred to as the “Guaranteed Obligations”). This Guaranty is a guaranty of payment and not just of collectibility and is in no way conditioned or contingent upon any attempt to collect from the Borrower or upon any other event, contingency or circumstance whatsoever. If for any reason whatsoever the Borrower shall fail or be unable duly, punctually and fully to pay such amounts as and when the same shall become due and payable, the Guarantor, without demand, presentment, protest or notice of any kind, will forthwith pay or cause to be paid such amounts to the Administrative Agent under the terms of the Credit Agreement, any Note or other relevant Loan Document, in lawful money of the United States, at the place specified in the Credit Agreement, or perform or comply with the same or cause the same to be performed or complied with, together with interest (to the extent provided for under the Credit Agreement) on any amount due and owing from the Borrower. The Guarantor, promptly after demand, will pay to the Administrative Agent the reasonable costs and expenses of collecting such amounts or otherwise enforcing this Guaranty, including, without limitation, the reasonable fees and expenses of counsel. Notwithstanding the foregoing, the right of recovery against the Guarantor under this Guaranty is limited to the extent it is judicially determined with respect to any Guarantor that entering into this Guaranty would violate Section 548 of the United States Bankruptcy Code or any comparable provisions of any state law, in which case such Guarantor shall be liable under this Guaranty only for amounts aggregating up to the largest amount that would not render such Guarantor’s obligations hereunder subject to avoidance under Section 548 of the United States Bankruptcy Code or any comparable provisions of any state law.

SECTION 2. Guarantor’s Obligations Unconditional. The obligations of the Guarantor under this Guaranty shall be primary, absolute and unconditional obligations of the Guarantor, shall not be subject to any counterclaim, set-off, deduction, diminution, abatement, recoupment, suspension, deferment, reduction or defense based upon any claim the Guarantor or any other Person may have against the Borrower or any other Person, and to the full extent permitted by applicable law shall remain in full force and effect without regard to, and shall not be released, discharged or in any way affected by, any circumstance or condition whatsoever (whether or not the Guarantor or the Borrower shall have any knowledge or notice thereof), including:

(a) any termination, amendment or modification of or deletion from or addition or supplement to or other change in the Credit Agreement, the Loan Documents or any other instrument or agreement applicable to any of the parties to any of the Loan Documents;

(b) any furnishing or acceptance of any security, or any release of any security, for the Guaranteed Obligations, or the failure of any security or the failure of any Person to perfect any interest in any collateral;

(c) any failure, omission or delay on the part of the Borrower to conform or comply with any term of any of the Loan Documents or any other instrument or agreement referred to in subsection (a) above, including, without limitation, failure to give notice to the Guarantor of the occurrence of a “Default” or an “Event of Default” under any Loan Document;

(d) any waiver of the payment, performance or observance of any of the obligations, conditions, covenants or agreements contained in any Loan Document, or any other waiver, consent, extension, indulgence, compromise, settlement, release or other action or inaction under or in respect of any of the Loan Documents or any other instrument or agreement referred to in subsection (a) above or any obligation or liability of the Borrower, or any exercise or non-exercise of any right, remedy, power or privilege under or in respect of any such instrument or agreement or any such obligation or liability;

(e) any failure, omission or delay on the part of any of the Administrative Agent or the Lenders to enforce, assert or exercise any right, power or remedy conferred on the Administrative Agent or the Lenders in this Guaranty, or any such failure, omission or delay on the part of the Administrative Agent or the Lenders in connection with any Loan Document, or any other action on the part of the Administrative Agent or the Lenders;

(f) any voluntary or involuntary bankruptcy, insolvency, reorganization, arrangement, readjustment, assignment for the benefit of creditors, composition, receivership, conservatorship, custodianship, liquidation, marshaling of assets and liabilities or similar proceedings with respect to the Borrower, any Guarantor or any other Person or any of their respective properties or creditors, or any action taken by any trustee or receiver or by any court in any such proceeding;

(g) any discharge, termination, cancellation, frustration, irregularity, invalidity or unenforceability, in whole or in part, of any of the Loan Documents or any other agreement or instrument referred to in subsection (a) above or any term hereof;

(h) any merger or consolidation of the Borrower or any Guarantor into or with any other corporation, or any sale, lease or transfer of any of the assets of the Borrower or any Guarantor to any other Person;

(i) any change in the ownership of any shares of capital stock of the Borrower or any change in the corporate relationship between the Borrower and the Guarantor, or any termination of such relationship;

(j) any release or discharge, by operation of law, of the Guarantor from the performance or observance of any obligation, covenant or agreement contained in this Guaranty; or

(k) any other occurrence, circumstance, happening or event whatsoever, whether similar or dissimilar to the foregoing, whether foreseen or unforeseen, and any other circumstance which might otherwise constitute a legal or equitable defense or discharge of the liabilities of a guarantor or surety or which might otherwise limit recourse against the Guarantor.

SECTION 3. Full Recourse Obligations. The obligations of the Guarantor set forth herein constitute the full recourse payment obligations of the Guarantor enforceable thereagainst to the fullest extent of all each Guarantors’ assets and properties.

SECTION 4. Waiver. The Guarantor unconditionally waives, to the extent permitted by applicable law, (a) notice of any of the matters referred to in Section 2 hereof, (b) notice to the Guarantor of the incurrence of any of the Guaranteed Obligations, notice to the Guarantor or the Borrower of any breach or default by the Borrower or the Guarantor with respect to any of the Guaranteed Obligations or any other notice that may be required, by statute, rule of law or otherwise, to preserve any rights of the Administrative Agent or the Lenders against the Guarantor, (c) presentment to or demand of payment from the Borrower or the Guarantors with respect to any amount due under any Loan Document or protest for nonpayment or dishonor, (d) any right to the enforcement, assertion or exercise by the Administrative Agent or the Lenders of any right, power, privilege or remedy conferred in the Credit Agreement or any other Loan Document or otherwise, (e) any requirement of diligence on the part of any of the Administrative Agent or the Lenders, (f) any requirement to exhaust any remedies or to mitigate the damages resulting from any default under any Loan Document, (g) any notice of any sale, transfer or other disposition by any of the Lenders of any right, title to or interest in the Credit Agreement or in any other Loan Document, and (h) any other circumstance whatsoever which might otherwise constitute a legal or equitable discharge, release or defense of a guarantor or surety or which might otherwise limit recourse against the Guarantor.

SECTION 5. Subrogation, Contribution, Reimbursement or Indemnity. Until one year and one day after all Guaranteed Obligations have been indefeasibly paid in full, the Guarantor agrees not to take any action pursuant to any rights which may have arisen in connection with this Guaranty to be subrogated to any of the rights (whether contractual, under the United States Bankruptcy Code, as amended, including Section 509 thereof, under common law or otherwise) of any of the Lenders against the Borrower or against any collateral security or guaranty or right of offset held by the Administrative Agent or the Lenders for the payment of the Guaranteed Obligations. Until one year and one day after all Guaranteed Obligations have been indefeasibly paid in full, the Guarantor agrees not to take any action pursuant to any contractual, common law, statutory or other rights of reimbursement, contribution, exoneration or indemnity (or any similar right) from or against the Borrower which may have arisen in connection with this Guaranty. So long as the Guaranteed Obligations remain, if any amount shall be paid by or on behalf of the Borrower to any Guarantor on account of any of the rights waived in this Section 5, such amount shall be held by such Guarantor in trust, segregated from other funds of such Guarantor, and shall, forthwith upon receipt by such Guarantor, be turned over to the Administrative Agent (duly endorsed by such Guarantor to the Administrative Agent, if required), to be applied against the Guaranteed Obligations, whether matured or unmatured, in such order as the Administrative Agent may determine. The provisions of this Section 5 shall survive the term of this Guaranty and the payment in full of the Guaranteed Obligations.

SECTION 6. Effect of Bankruptcy or Insolvency Proceedings. This Guaranty shall continue to be effective or be automatically reinstated, as the case may be, if at any time payment, in whole or in part, of any of the sums due to any of the Lenders pursuant to the terms of the Credit Agreement or any other Loan Document is rescinded or must otherwise be restored or returned by such Lender upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of the Borrower or any other Person, or upon or as a result of the appointment of a custodian, receiver, trustee or other officer with similar powers with respect to the Borrower or other Person or any substantial part of its property, or otherwise, all as though such payment had not been made. If an event permitting the acceleration of the maturity of the principal amount of the Notes shall at any time have occurred and be continuing, and such acceleration shall at such time be prevented by reason of the pendency against the Borrower or any other Person of a case or proceeding under a bankruptcy or insolvency law, the Guarantor agrees that, for purposes of this Guaranty and its obligations hereunder, the maturity of the principal amount of the Notes and all other Guaranteed Obligations shall be deemed to have been accelerated with the same effect as if the Lenders had accelerated the same in accordance with the terms of the Credit Agreement or other applicable Loan Document, and the Guarantor shall forthwith pay such principal amount and interest thereon and any other amounts guaranteed hereunder without further notice or demand.

SECTION 7. Termination. This Guaranty shall terminate when, and only when, all of the Guaranteed Obligations have been paid and performed in full, all in accordance with the provisions of the Credit Agreement.

SECTION 8. Representations and Warranties. Guarantor represents and warrants that:

(a) It (i) is duly organized, validly existing in good standing under the laws of the jurisdiction of its incorporation or organization, (ii) has the corporate or other necessary organizational power and authority, and the legal right to own and operate its Properties, to lease the Properties it operates as lessee and to conduct the business in which it is currently engaged, (iii) is duly qualified as a foreign entity and in good standing under the laws of each jurisdiction where its ownership, lease or operation of Property or the conduct of its business requires such qualification, other than in such jurisdictions where the failure to be so qualified and in good standing has not had and could not have a Material Adverse Effect, and (iv) is in compliance with all applicable law, except to the extent that the failure to comply therewith has not had and could not be reasonably expected to have a Material Adverse Effect.

(b) It has the power and authority and legal right to execute and deliver this Guaranty and to perform its obligations hereunder. The execution and delivery by it of this Guaranty and the performance of its obligations hereunder have been duly authorized by proper proceedings. No consent or authorization of, filing with, notice to or other act by or in respect of, any Governmental Authority or other Person is required in connection with its execution and delivery of this Guaranty and performance of its obligations hereunder (other than those which have been obtained).

(c) This Guaranty constitutes a legal, valid and binding obligation of the Guarantor, enforceable against it in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors’ rights generally and by general equitable principles (whether enforcement is sought by proceedings in equity or at law).

(d) The execution, delivery and performance of this Guaranty will not violate any applicable law or any material agreement, instrument or undertaking to which any Guarantor is a party or by which it or any of its Property is bound (collectively, a “Contractual Obligation”) of the Guarantor (except those as to which waivers or consents have been obtained and those which could not reasonably be expected to have a Material Adverse Effect), and will not result in, or require, the creation or imposition of any Lien on any of its Properties or revenues pursuant to any applicable law or Contractual Obligation.

(e) It has a substantial economic interest in the Borrower and expects to derive benefits from transactions resulting in the creation of the Guaranteed Obligations hereby. The Administrative Agent and the Lenders may rely conclusively on a continuing warranty hereby made, that each Guarantor continues to be benefited by the Lenders’ extension of credit to the Borrower, and neither the Administrative Agent nor the Lenders shall have any duty to inquire into or confirm the receipt of any such benefits, and this Guaranty shall be effective and enforceable by the Administrative Agent and the Lenders without regard to the receipt, nature or value of any such benefits.

(f) It has received a full and complete copy of the executed Credit Agreement (with exhibits, annexes and schedules attached thereto).

SECTION 9. Limitations on Obligations.

(a) The provisions of this Guaranty are severable, and in any action or proceeding involving any state corporate law, or any state, federal or foreign bankruptcy, insolvency, reorganization or other law affecting the rights of creditors generally, if the obligations of any Guarantor under this Guaranty would otherwise be held or determined to be avoidable, invalid or unenforceable on account of the amount of such Guarantor’s liability under this Guaranty, then, notwithstanding any other provision of this Guaranty to the contrary, the amount of such liability shall, without any further action by such Guarantor, the Administrative Agent or the Lenders, be automatically limited and reduced to the highest amount that is valid and enforceable as determined in such action or proceeding (such highest amount determined hereunder being the relevant Guarantor’s “Maximum Liability”). This Section 9(a) with respect to the Maximum Liability of any Guarantor is intended solely to preserve the rights of the Administrative Agent and the Lenders to the maximum extent not subject to avoidance under applicable law, and neither any Guarantor nor any other Person or entity shall have any right or claim under this Section 9(a) with respect to the Maximum Liability, except to the extent necessary so that the obligations of any Guarantor hereunder shall not be rendered voidable under applicable law.

(b) The Guarantor agrees that the Guaranteed Obligations may at any time and from time to time exceed the Maximum Liability of Guarantor, and may exceed the aggregate Maximum Liability of any other guarantors, without impairing this Guaranty or affecting the rights and remedies of the Administrative Agent or the Lenders. Nothing in this Section 9(b) shall be construed to increase any Guarantor’s obligations hereunder beyond its Maximum Liability.

(c) In the event any Guarantor (a “Paying Guarantor”) shall make any payment or payments under this Guaranty or shall suffer any loss as a result of any realization upon any collateral granted by it to secure its obligations under this Guaranty, any other guarantor (each a “Non-Paying Guarantor”) shall contribute to such Paying Guarantor an amount equal to such Non-Paying Guarantor’s “Pro Rata Share” of such payment or payments made, or losses suffered, by such Paying Guarantor. For the purposes hereof, each Non-Paying Guarantor’s “Pro Rata Share” with respect to any such payment or loss by a Paying Guarantor shall be determined as of the date on which such payment or loss was made by reference to the ratio of (i) such Non-Paying Guarantor’s Maximum Liability as of such date (without giving effect to any right to receive, or obligation to make, any contribution hereunder) or, if such Non-Paying Guarantor’s Maximum Liability has not been determined, the aggregate amount of all monies received by such Non-Paying Guarantor from the Borrower after the date hereof (whether by loan, capital infusion or by other means) to (ii) the aggregate Maximum Liability of all guarantors hereunder (including such Paying Guarantor) as of such date (without giving effect to any right to receive, or obligation to make, any contribution hereunder), or to the extent that a Maximum Liability has not been determined for any guarantors, the aggregate amount of all monies received by such guarantors from the Borrower after the date hereof (whether by loan, capital infusion or by other means). Nothing in this Section 9(c) shall affect any Guarantor’s or any other guarantor’s several liability for the entire amount of the Guaranteed Obligations (up to such guarantor’s Maximum Liability). Each Guarantor covenants and agrees that its right to receive any contribution under this Guaranty from a Non-Paying Guarantor shall be subordinate and junior in right of payment to all the Guaranteed Obligations. The provisions of this Section 9(c) are for the benefit of the Administrative Agent, the Lenders and the Guarantor and may be enforced by any one, or more, or all of them in accordance with the terms hereof.
