ARTICLE II

THE CREDITS

2.1. Commitment. From and including the date of this Agreement and prior to the Facility Termination Date, each Lender severally agrees, on the terms and conditions set forth in this Agreement, to (i) make Loans to the Borrower and (ii) participate in Facility LCs issued upon the request of the Borrower, in an amount not to exceed at any time outstanding the lesser of (x) the Commitment of such Lender or (y) the Pro Rata Share of such Lender of the Borrowing Base then in effect, provided that, after giving effect to the making of each such Loan and the issuance of each such Facility LC, such Lender’s Outstanding Credit Exposure shall not exceed its Commitment. Subject to the terms of this Agreement, the Borrower may borrow, repay and reborrow at any time prior to the Facility Termination Date. The Commitments to extend credit hereunder shall expire on the Facility Termination Date. The LC Issuer will issue Facility LCs hereunder on the terms and conditions set forth in Section 2.19.

2.2. Required Payments; Termination. The Aggregate Outstanding Credit Exposure and all other unpaid Obligations shall be paid in full by the Borrower on the Facility Termination Date.

2.3. Ratable Loans. Each Advance hereunder shall consist of Loans made from the several Lenders ratably according to their Pro Rata Shares.

2.4. Types of Advances. The Advances may be Floating Rate Advances or Eurodollar Advances, or a combination thereof, selected by the Borrower in accordance with Sections 2.8 and 2.9.

2.5. Commitment Fee; Increases and Reductions in Aggregate Commitment.

(i) The Borrower agrees to pay to the Administrative Agent for the account of each Lender according to its Pro Rata Share a commitment fee at a per annum rate equal to the Applicable Fee Rate on the average daily Available Aggregate Commitment from the date hereof to and including the Facility Termination Date, payable on each Payment Date hereafter and on the Facility Termination Date. All accrued commitment fees shall be payable on the effective date of any termination of the obligations of the Lenders to make Credit Extensions hereunder.

(ii) The Borrower shall have the right, with the prior written consent of the Administrative Agent (provided that such consent shall not be unreasonably withheld or delayed), to increase the Aggregate Commitment; provided that notwithstanding anything to the contrary in this Agreement, (a) the Aggregate Commitment after giving effect to such proposed increase or increases shall not exceed the lesser of (1) the Borrowing Base then in effect, and (2) $300,000,000, (b) each Lender shall be offered a Pro Rata Share of such proposed increase, (c) no Default or Unmatured Default shall have occurred and be continuing at the effective date of such proposed increase, (d) on the effective date of such increase, no Eurodollar Loans shall be outstanding (or if any Eurodollar Loans are outstanding, the effective date of such increase shall

be the last day of the Interest Period in respect of such Eurodollar Loans), (e) no Lender’s Commitment may be increased or decreased without the consent of such Lender and (f) if necessary, other eligible financial institutions may become Lenders to accommodate such proposed increase.

If the Borrower desires to effect an increase in the Aggregate Commitment, the Borrower and the financial institution(s) that the Borrower proposes to become a Lender hereunder, and, if applicable, the existing Lender(s) that the Borrower proposes to increase its existing Commitment shall (subject at all times to the consent of each such financial institution or each such existing Lender, as applicable) execute and deliver to the Administrative Agent a certificate substantially in the form of Exhibit D hereto (an “Additional Lender Certificate”). Upon receipt of such Additional Lender Certificate, if the Administrative Agent consents to the proposed increase in the Aggregate Commitment: (1) the amount of the Aggregate Commitment shall be so increased, (2) the Administrative Agent shall amend and distribute to the Borrower and the Lenders a revised schedule of Commitments for each Lender adding or amending, as applicable, the Commitment of any Lender executing the Additional Lender Certificate and the revised Pro Rata Shares of the Lenders, (3) any such additional Lender shall be deemed to be a party in all respect to this Agreement and the other Loan Documents as of the effective date set forth in such Additional Lender Certificate and (4) upon the effective date set forth in such Additional Lender Certificate, any such Lender party to the Additional Lender Certificate shall purchase a pro rata portion of the outstanding Loans (and participation interests in Facility LCs) of each of the current Lenders such that the Lenders (including any additional Lender, if applicable) shall hold their Pro Rata Share of the outstanding Loans (and participation interests) as reflected in the revised schedule of Commitments required by this Section 2.5(ii). If the Administrative Agent does not consent to the increase in the Aggregate Commitment in accordance with this Section 2.5(ii), the Commitment shall remain unchanged.

(iii) The Borrower shall have the right to permanently reduce the Aggregate Commitment in whole, or in part ratably among the Lenders in integral multiples of $5,000,000, upon at least three Business Days’ written notice to the Administrative Agent, which notice shall specify the amount of any such reduction, provided, however, that the amount of the Aggregate Commitment may not be reduced below the Aggregate Outstanding Credit Exposure.

2.6. Minimum Amount of Each Advance. Each Eurodollar Advance shall be in the minimum amount of $1,000,000 (and in multiples of $500,000 if in excess thereof), and each Floating Rate Advance shall be in the minimum amount of $500,000 (and in multiples of $100,000 if in excess thereof), provided, however, that any Floating Rate Advance may be in the amount of the Available Aggregate Commitment.

2.7. Prepayments.

2.7.1. Optional Payments. The Borrower may from time to time pay, without penalty or premium, all outstanding Floating Rate Advances, or, in a minimum aggregate amount of $1,000,000 or any integral multiple of $1,000,000 in excess thereof, any portion of the outstanding Floating Rate Advances upon one Business Day’s prior notice to the Administrative Agent. The Borrower may from time to time pay, subject to the payment of any funding indemnification amounts required by Section 3.4 but without penalty or premium, all outstanding

Eurodollar Advances, or, in a minimum aggregate amount of $1,000,000 or any integral multiple of $1,000,000 in excess thereof, any portion of the outstanding Eurodollar Advances upon three Business Days’ prior notice to the Administrative Agent.

2.7.2. Mandatory Payments. If at any time the Aggregate Outstanding Credit Exposure exceeds the Borrowing Base then in effect (whether as a result of any adjustment or redetermination of the Borrowing Base in accordance with Sections 2.21, 6.1.8(iv) or 6.2.11 or otherwise), the Borrower shall (a) prepay the Loans 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 any funding indemnification amounts required by Section 3.4, and (b) if a Borrowing Base Deficiency remains after prepaying all of the Loans as a result of LC Obligations, pay to the Administrative Agent on behalf of the Lenders an amount equal to such Borrowing Base Deficiency to be held as cash collateral in a special collateral account as provided in Section 2.19.11. The Borrower shall be obligated to make such prepayment and/or deposit of cash collateral within sixty (60) days following its receipt of written notice from the Administrative Agent of any Borrowing Base Deficiency.

2.8. Method of Selecting Types and Interest Periods for New Advances. The Borrower shall select the Type of Advance and, in the case of each Eurodollar Advance, the Interest Period applicable thereto from time to time. The Borrower shall give the Administrative Agent irrevocable notice (a “Borrowing Notice”) not later than 10:00 a.m. (Chicago time) at least one Business Day before the Borrowing Date of each Floating Rate Advance and three Business Days before the Borrowing Date for each Eurodollar Advance, specifying: (i) the Borrowing Date, which shall be a Business Day, of such Advance, (ii) the aggregate amount of such Advance, (iii) the Type of Advance selected, and (iv) in the case of each Eurodollar Advance, the Interest Period applicable thereto. Not later than noon (Chicago time) on each Borrowing Date, each Lender shall make available its Loan or Loans in funds immediately available in Chicago to the Administrative Agent at its address specified pursuant to Article XIII. The Administrative Agent will make the funds so received from the Lenders available to the Borrower at the Administrative Agent’s aforesaid address.

2.9. Conversion and Continuation of Outstanding Advances. Floating Rate Advances shall continue as Floating Rate Advances unless and until such Floating Rate Advances are converted into Eurodollar Advances pursuant to this Section 2.9 or are repaid in accordance with Section 2.7. Each Eurodollar Advance shall continue as a Eurodollar Advance until the end of the then applicable Interest Period therefor, at which time such Eurodollar Advance shall be automatically converted into a Floating Rate Advance unless (x) such Eurodollar Advance is or was repaid in accordance with Section 2.7 or (y) the Borrower shall have given the Administrative Agent a Conversion/Continuation Notice (as defined below) requesting that, at the end of such Interest Period, such Eurodollar Advance continue as a Eurodollar Advance for the same or another Interest Period. Subject to the terms of Section 2.6, the Borrower may elect from time to time to convert all or any part of a Floating Rate Advance into a Eurodollar Advance. The Borrower shall give the Administrative Agent irrevocable notice (a “Conversion/Continuation Notice”) of each conversion of a Floating Rate Advance into a Eurodollar Advance or continuation of a Eurodollar Advance not later than 10:00 a.m. (Chicago time) at least three Business Days prior to the date of the requested conversion or continuation, specifying: (i) the requested date, which shall be a Business Day, of such conversion or

continuation, (ii) the aggregate amount and Type of the Advance which is to be converted or continued, and (iii) the amount of such Advance which is to be converted into or continued as a Eurodollar Advance and the duration of the Interest Period applicable thereto.

2.10. Changes in Interest Rate, etc. Each Floating Rate Advance shall bear interest on the outstanding principal amount thereof, for each day from and including the date such Advance is made or is automatically converted from a Eurodollar Advance into a Floating Rate Advance pursuant to Section 2.9, to but excluding the date it is paid or is converted into a Eurodollar Advance pursuant to Section 2.9 hereof, at a rate per annum equal to the Floating Rate for such day. Changes in the rate of interest on that portion of any Advance maintained as a Floating Rate Advance will take effect simultaneously with each change in the Alternate Base Rate. Each Eurodollar Advance shall bear interest on the outstanding principal amount thereof from and including the first day of the Interest Period applicable thereto to (but not including) the last day of such Interest Period at the interest rate determined by the Administrative Agent as applicable to such Eurodollar Advance based upon the Borrower’s selections under Sections 2.8 and 2.9 and otherwise in accordance with the terms hereof. No Interest Period may end after the Facility Termination Date.

2.11. Rates Applicable After Default. Notwithstanding anything to the contrary contained in Section 2.8, 2.9 or 2.10, during the continuance of a Default or Unmatured Default the Required Lenders may, at their option, by notice to the Borrower (which notice may be revoked at the option of the Required Lenders notwithstanding any provision of Section 8.2 requiring unanimous consent of the Lenders to changes in interest rates), declare that no Advance may be made as, converted into or continued as a Eurodollar Advance. During the continuance of a Default the Required Lenders may, at their option, by notice to the Borrower (which notice may be revoked at the option of the Required Lenders notwithstanding any provision of Section 8.2 requiring unanimous consent of the Lenders to changes in interest rates), declare that (i) each Eurodollar Advance shall bear interest for the remainder of the applicable Interest Period at the rate otherwise applicable to such Interest Period plus two percent (2%) per annum, (ii) each Floating Rate Advance shall bear interest at a rate per annum equal to the Floating Rate in effect from time to time plus two percent (2%) per annum and (iii) the LC Fee shall be increased by two percent (2%) per annum, provided that, during the continuance of a Default under Section 7.1(vi) or 7.1(vii), the interest rates set forth in clauses (i) and (ii) above and the increase in the LC Fee set forth in clause (iii) above shall be applicable to all Credit Extensions without any election or action on the part of the Administrative Agent or any Lender.

2.12. Method of Payment. All payments of the Obligations hereunder shall be made, without setoff, deduction, or counterclaim, in immediately available funds to the Administrative Agent at the Administrative Agent’s address specified pursuant to Article XIII, or at any other Lending Installation of the Administrative Agent specified in writing by the Administrative Agent to the Borrower, by noon (local time) on the date when due and shall (except in the case of Reimbursement Obligations for which the LC Issuer has not been fully indemnified by the Lenders, or as otherwise specifically required hereunder) be applied ratably by the Administrative Agent among the Lenders. Each payment delivered to the Administrative Agent for the account of any Lender shall be delivered promptly by the Administrative Agent to such Lender in the same type of funds that the Administrative Agent received at its address specified pursuant to Article XIII or at any Lending Installation specified in a notice received by the

Administrative Agent from such Lender. The Administrative Agent is hereby authorized to charge the account of the Borrower maintained with Bank One for each payment of principal, interest, Reimbursement Obligations and fees as it becomes due hereunder. Each reference to the Administrative Agent in this Section 2.12 shall also be deemed to refer, and shall apply equally, to the LC Issuer, in the case of payments required to be made by the Borrower to the LC Issuer pursuant to Section 2.19.6.

2.13. Noteless Agreement; Evidence of Indebtedness. (i) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to such Lender resulting from each Loan made by such Lender from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder.

(ii) The Administrative Agent shall also maintain accounts in which it will record (a) the amount of each Loan made hereunder, the Type thereof and the Interest Period with respect thereto, (b) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder, (c) the original stated amount of each Facility LC and the amount of LC Obligations outstanding at any time, and (d) the amount of any sum received by the Administrative Agent hereunder from the Borrower and each Lender’s share thereof.

(iii) The entries maintained in the accounts maintained pursuant to paragraphs (i) and (ii) above shall be prima facie evidence of the existence and amounts of the Obligations therein recorded; provided, however, that the failure of the Administrative Agent or any Lender to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Obligations in accordance with their terms.

(iv) Any Lender may request that its Loans be evidenced by a promissory note (a “Note”). In such event, the Borrower shall prepare, execute and deliver to such Lender a Note payable to the order of such Lender in a form supplied by the Administrative Agent. Thereafter, the Loans evidenced by such Note and interest thereon shall at all times (prior to any assignment pursuant to Section 12.3) be represented by one or more Notes payable to the order of the payee named therein, except to the extent that any such Lender subsequently returns any such Note for cancellation and requests that such Loans once again be evidenced as described in paragraphs (i) and (ii) above.

2.14. Telephonic Notices. The Borrower hereby authorizes the Lenders and the Administrative Agent to extend, convert or continue Advances, effect selections of Types of Advances and to transfer funds based on telephonic notices made by any person or persons the Administrative Agent or any Lender in good faith believes to be acting on behalf of the Borrower, it being understood that the foregoing authorization is specifically intended to allow Borrowing Notices and Conversion/Continuation Notices to be given telephonically. The Borrower agrees to deliver promptly to the Administrative Agent a written confirmation, if such confirmation is requested by the Administrative Agent or any Lender, of each telephonic notice signed by an Authorized Officer. If the written confirmation differs in any material respect from the action taken by the Administrative Agent and the Lenders, the records of the Administrative Agent and the Lenders shall govern absent manifest error.

2.15. Interest Payment Dates; Interest and Fee Basis. Interest accrued on each Floating Rate Advance shall be payable on each Payment Date, commencing with the first such date to occur after the date hereof, on any date on which the Floating Rate Advance is prepaid, whether due to acceleration or otherwise, and at maturity. Interest accrued on that portion of the outstanding principal amount of any Floating Rate Advance converted into a Eurodollar Advance on a day other than a Payment Date shall be payable on the date of conversion. Interest accrued on each Eurodollar Advance shall be payable on the last day of its applicable Interest Period, on any date on which the Eurodollar Advance is prepaid, whether by acceleration or otherwise, and at maturity. Interest accrued on each Eurodollar Advance having an Interest Period longer than three months shall also be payable on the last day of each three-month interval during such Interest Period. Interest and commitment fees for Eurodollar Advances and LC Fees shall be calculated for actual days elapsed on the basis of a 360-day year. Interest and commitment fees for Floating Rate Advances shall be calculated for actual days elapsed on the basis of a 365-day, or where appropriate 366-day, year. Interest shall be payable for the day an Advance is made but not for the day of any payment on the amount paid if payment is received prior to noon (local time) at the place of payment. If any payment of principal of or interest on an Advance shall become due on a day which is not a Business Day, such payment shall be made on the next succeeding Business Day and, in the case of a principal payment, such extension of time shall be included in computing interest in connection with such payment.

2.16. Notification of Advances, Interest Rates, Prepayments and Commitment Reductions. Promptly after receipt thereof, the Administrative Agent will notify each Lender of the contents of each Aggregate Commitment reduction notice, Borrowing Notice, Conversion/Continuation Notice, and repayment notice received by it hereunder. Promptly after notice from the LC Issuer, the Administrative Agent will notify each Lender of the contents of each request for issuance of a Facility LC hereunder. The Administrative Agent will notify each Lender of the interest rate applicable to each Eurodollar Advance promptly upon determination of such interest rate and will give each Lender prompt notice of each change in the Alternate Base Rate.

2.17. Lending Installations. Each Lender may book its Loans and its participation in any LC Obligations and the LC Issuer may book the Facility LCs at any Lending Installation selected by such Lender or the LC Issuer, as the case may be, and may change its Lending Installation from time to time. All terms of this Agreement shall apply to any such Lending Installation and the Loans, Facility LCs, participations in LC Obligations and any Notes issued hereunder shall be deemed held by each Lender or the LC Issuer, as the case may be, for the benefit of any such Lending Installation. Each Lender and the LC Issuer may, by written notice to the Administrative Agent and the Borrower in accordance with Article XIII, designate replacement or additional Lending Installations through which Loans will be made by it or Facility LCs will be issued by it and for whose account Loan payments or payments with respect to Facility LCs are to be made.

2.18. Non-Receipt of Funds by the Administrative Agent. Unless the Borrower or a Lender, as the case may be, notifies the Administrative Agent prior to the date on which it is scheduled to make payment to the Administrative Agent of (i) in the case of a Lender, the proceeds of a Loan or (ii) in the case of the Borrower, a payment of principal, interest or fees to the Administrative Agent for the account of the Lenders, that it does not intend to make such

payment, the Administrative Agent may assume that such payment has been made. The Administrative Agent may, but shall not be obligated to, make the amount of such payment available to the intended recipient in reliance upon such assumption. If such Lender or the Borrower, as the case may be, has not in fact made such payment to the Administrative Agent, the recipient of such payment shall, on demand by the Administrative Agent, repay to the Administrative 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 Administrative Agent until the date the Administrative Agent recovers such amount at a rate per annum equal to (x) in the case of payment by a Lender, the Federal Funds Effective Rate for such day for the first three days and, thereafter, the interest rate applicable to the relevant Loan or (y) in the case of payment by the Borrower, the interest rate applicable to the relevant Loan.

2.19. Facility LCs.

2.19.1. Issuance. The LC Issuer hereby agrees, on the terms and conditions set forth in this Agreement, to issue standby and commercial letters of credit (each, a “Facility LC”) and to renew, extend, increase, decrease or otherwise modify each Facility LC (“Modify,” and each such action a “Modification”), from time to time from and including the date of this Agreement and prior to the Facility Termination Date upon the request of the Borrower; provided that immediately after each such Facility LC is issued or Modified, (i) the aggregate amount of the outstanding LC Obligations shall not exceed $20,000,000 and (ii) the Aggregate Outstanding Credit Exposure shall not exceed the Aggregate Commitment. No Facility LC shall have an expiry date later than the earlier of (x) the fifth Business Day prior to the Facility Termination Date and (y) one year after its issuance, provided, however, that any Facility LC with a one-year term may provide for the renewal thereof for additional one-year periods (which shall in no event extend beyond the fifth business day prior to the Facility Termination Date) unless the Issuer provides prior notice of non-renewal to the beneficiary.

2.19.2. Participations. Upon the issuance or Modification by the LC Issuer of a Facility LC in accordance with this Section 2.19, the LC Issuer shall be deemed, without further action by any party hereto, to have unconditionally and irrevocably sold to each Lender, and each Lender shall be deemed, without further action by any party hereto, to have unconditionally and irrevocably purchased from the LC Issuer, a participation in such Facility LC (and each Modification thereof) and the related LC Obligations in proportion to its Pro Rata Share.

2.19.3. Notice. Subject to Section 2.19.1, the Borrower shall give the LC Issuer notice prior to 10:00 a.m. (Chicago time) at least five Business Days prior to the proposed date of issuance or Modification of each Facility LC, specifying the beneficiary, the proposed date of issuance (or Modification) and the expiry date of such Facility LC, and describing the proposed terms of such Facility LC and the nature of the transactions proposed to be supported thereby. Upon receipt of such notice, the LC Issuer shall promptly notify the Administrative Agent, and the Administrative Agent shall promptly notify each Lender, of the contents thereof and of the amount of such Lender’s participation in such proposed Facility LC. The issuance or Modification by the LC Issuer of any Facility LC shall, in addition to the conditions precedent set forth in Article IV (the satisfaction of which the LC Issuer shall have no duty to ascertain), be subject to the conditions precedent that such Facility LC shall be satisfactory to the LC Issuer and that the Borrower shall have executed and delivered such application agreement and/or such

other instruments and agreements relating to such Facility LC as the LC Issuer shall have reasonably requested (each, a “Facility LC Application”). In the event of any conflict between the terms of this Agreement and the terms of any Facility LC Application, the terms of this Agreement shall control.

2.19.4. LC Fees. The Borrower shall pay to the Administrative Agent, for the account of the Lenders ratably in accordance with their respective Pro Rata Shares, with respect to each standby Facility LC, a letter of credit fee at a per annum rate equal to the Applicable Margin for Eurodollar Loans in effect from time to time (which fee shall be increased by two percent (2%) per annum after the occurrence of an Default) on the average daily undrawn stated amount under such standby Facility LC, such fee to be payable in arrears on each Payment Date beginning with the first Payment Date after such Facility LC is issued (“LC Fee”). The Borrower shall also pay to the LC Issuer for its own account (i) at the time of issuance of each Facility LC, a fronting fee for each Facility LC equal to the greater of (x) $500 or (y) 0.125% per annum on the initial stated amount thereof, such fee to be payable in arrears on each Payment Date beginning with the first Payment Date after such Facility LC is issued, and (ii) documentary and processing charges in connection with the issuance, Modification, cancellation, negotiation or transfer of and draws under Facility LCs in accordance with the LC Issuer’s standard schedule for such charges as in effect from time to time.

2.19.5. Administration; Reimbursement by Lenders. Upon receipt from the beneficiary of any Facility LC of any demand for payment under such Facility LC, the LC Issuer shall notify the Administrative Agent and the Administrative Agent shall promptly notify the Borrower and each other Lender as to the amount to be paid by the LC Issuer as a result of such demand and the proposed payment date (the “LC Payment Date”). The responsibility of the LC Issuer to the Borrower and each Lender shall be only to determine that the documents (including each demand for payment) delivered under each Facility LC in connection with such presentment shall be in conformity in all material respects with such Facility LC. The LC Issuer shall endeavor to exercise the same care in the issuance and administration of the Facility LCs as it does with respect to letters of credit in which no participations are granted, it being understood that in the absence of any gross negligence or willful misconduct by the LC Issuer, each Lender shall be unconditionally and irrevocably liable without regard to the occurrence of any Default or any condition precedent whatsoever, to reimburse the LC Issuer on demand for (i) such Lender’s Pro Rata Share of the amount of each payment made by the LC Issuer under each Facility LC to the extent such amount is not reimbursed by the Borrower pursuant to Section 2.19.6 below, plus (ii) interest on the foregoing amount to be reimbursed by such Lender, for each day from the date of the LC Issuer’s demand for such reimbursement (or, if such demand is made after 11:00 a.m. (Chicago time) on such date, from the next succeeding Business Day) to the date on which such Lender pays the amount to be reimbursed by it, at a rate of interest per annum equal to the Federal Funds Effective Rate for the first three days and, thereafter, at a rate of interest equal to the rate applicable to Floating Rate Advances.

2.19.6. Reimbursement by Borrower. The Borrower shall be irrevocably and unconditionally obligated to reimburse the LC Issuer on or before the applicable LC Payment Date for any amounts to be paid by the LC Issuer upon any drawing under any Facility LC, without presentment, demand, protest or other formalities of any kind; provided that neither the Borrower nor any Lender shall hereby be precluded from asserting any claim for direct (but not

consequential) damages suffered by the Borrower or such Lender to the extent, but only to the extent, caused by (i) the willful misconduct or gross negligence of the LC Issuer in determining whether a request presented under any Facility LC issued by it complied with the terms of such Facility LC or (ii) the LC Issuer’s failure to pay under any Facility LC issued by it after the presentation to it of a request strictly complying with the terms and conditions of such Facility LC. All such amounts paid by the LC Issuer and remaining unpaid by the Borrower shall bear interest, payable on demand, for each day until paid at a rate per annum equal to (x) the rate applicable to Floating Rate Advances for such day if such day falls on or before the applicable LC Payment Date and (y) the sum of two percent (2%) plus the rate applicable to Floating Rate Advances for such day if such day falls after such LC Payment Date. The LC Issuer will pay to each Lender ratably in accordance with its Pro Rata Share all amounts received by it from the Borrower for application in payment, in whole or in part, of the Reimbursement Obligation in respect of any Facility LC issued by the LC Issuer, but only to the extent such Lender has made payment to the LC Issuer in respect of such Facility LC pursuant to Section 2.19.5. Subject to the terms and conditions of this Agreement (including without limitation the submission of a Borrowing Notice in compliance with Section 2.8 and the satisfaction of the applicable conditions precedent set forth in Article IV), the Borrower may request an Advance hereunder for the purpose of satisfying any Reimbursement Obligation.

2.19.7. Obligations Absolute. The Borrower’s obligations under this Section 2.19 shall be absolute and unconditional under any and all circumstances and irrespective of any setoff, counterclaim or defense to payment which the Borrower may have or have had against the LC Issuer, any Lender or any beneficiary of a Facility LC. The Borrower further agrees with the LC Issuer and the Lenders that the LC Issuer and the Lenders shall not be responsible for, and the Borrower’s Reimbursement Obligation in respect of any Facility LC shall not be affected by, among other things, the validity or genuineness of documents or of any endorsements thereon, even if such documents should in fact prove to be in any or all respects invalid, fraudulent or forged, or any dispute between or among the Borrower, any of its Affiliates, the beneficiary of any Facility LC or any financing institution or other party to whom any Facility LC may be transferred or any claims or defenses whatsoever of the Borrower or of any of its Affiliates against the beneficiary of any Facility LC or any such transferee. The LC Issuer shall not be liable for any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with any Facility LC. The Borrower agrees that any action taken or omitted by the LC Issuer or any Lender under or in connection with each Facility LC and the related drafts and documents, if done without gross negligence or willful misconduct, shall be binding upon the Borrower and shall not put the LC Issuer or any Lender under any liability to the Borrower. Nothing in this Section 2.19.7 is intended to limit the right of the Borrower to make a claim against the LC Issuer for damages as contemplated by the proviso to the first sentence of Section 2.19.6.

2.19.8. Actions of LC Issuer. The LC Issuer shall be entitled to rely, and shall be fully protected in relying, upon any Facility LC, draft, writing, resolution, notice, consent, certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype message, statement, order or other document believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons, and upon advice and statements of legal counsel, independent accountants and other experts selected by the LC Issuer. The LC Issuer shall be fully justified in failing or refusing to take any action under this Agreement unless it shall first

have received such advice or concurrence of the Required Lenders as it reasonably deems appropriate or it shall first be indemnified to its reasonable satisfaction by the Lenders against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. Notwithstanding any other provision of this Section 2.19, the LC Issuer shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement in accordance with a request of the Required Lenders, and such request and any action taken or failure to act pursuant thereto shall be binding upon the Lenders and any future holders of a participation in any Facility LC.

2.19.9. Indemnification. The Borrower hereby agrees to indemnify and hold harmless each Lender, the LC Issuer and each Agent, and their respective directors, officers, agents and employees from and against any and all claims and damages, losses, liabilities, costs or expenses which such Lender, the LC Issuer or such Agent may incur (or which may be claimed against such Lender, the LC Issuer or such Agent by any Person whatsoever) by reason of or in connection with the issuance, execution and delivery or transfer of or payment or failure to pay under any Facility LC or any actual or proposed use of any Facility LC, including, without limitation, any claims, damages, losses, liabilities, costs or expenses which the LC Issuer may incur by reason of or in connection with (i) the failure of any other Lender to fulfill or comply with its obligations to the LC Issuer hereunder (but nothing herein contained shall affect any rights the Borrower may have against any defaulting Lender) or (ii) by reason of or on account of the LC Issuer issuing any Facility LC which specifies that the term “Beneficiary” included therein includes any successor by operation of law of the named Beneficiary, but which Facility LC does not require that any drawing by any such successor Beneficiary be accompanied by a copy of a legal document, satisfactory to the LC Issuer, evidencing the appointment of such successor Beneficiary; provided that the Borrower shall not be required to indemnify any Lender, the LC Issuer or such Agent for any claims, damages, losses, liabilities, costs or expenses to the extent, but only to the extent, caused by (x) the willful misconduct or gross negligence of the LC Issuer in determining whether a request presented under any Facility LC complied with the terms of such Facility LC or (y) the LC Issuer’s failure to pay under any Facility LC after the presentation to it of a request strictly complying with the terms and conditions of such Facility LC. Nothing in this Section 2.19.9 is intended to limit the obligations of the Borrower under any other provision of this Agreement.

2.19.10. Lenders’ Indemnification. Each Lender shall, ratably in accordance with its Pro Rata Share, indemnify the LC Issuer, its affiliates and their respective directors, officers, agents and employees (to the extent not reimbursed by the Borrower) against any cost, expense (including reasonable counsel fees and disbursements), claim, demand, action, loss or liability (except such as result from such indemnitees’ gross negligence or willful misconduct or the LC Issuer’s failure to pay under any Facility LC after the presentation to it of a request strictly complying with the terms and conditions of the Facility LC) that such indemnitees may suffer or incur in connection with this Section 2.19 or any action taken or omitted by such indemnitees hereunder.

2.19.11. Facility LC Collateral Account. The Borrower agrees that it will, upon the request of the Administrative Agent or the Required Lenders and until the final expiration date of any Facility LC and thereafter as long as any amount is payable to the LC Issuer or the Lenders in respect of any Facility LC, maintain a special collateral account pursuant to

arrangements satisfactory to the Administrative Agent (the “Facility LC Collateral Account”) at the Administrative Agent’s office at the address specified pursuant to Article XIII, in the name of such Borrower but under the sole dominion and control of the Administrative Agent, for the benefit of the Lenders and in which such Borrower shall have no interest other than as set forth in Section 8.1. The Borrower hereby pledges, assigns and grants to the Administrative Agent, on behalf of and for the ratable benefit of the Administrative Agent, the Lenders and the LC Issuer, a security interest in all of the Borrower’s right, title and interest in and to all funds which may from time to time be on deposit in the Facility LC Collateral Account to secure the prompt and complete payment and performance of the Obligations. The Administrative Agent will invest any funds on deposit from time to time in the Facility LC Collateral Account in certificates of deposit of Bank One having a maturity not exceeding 30 days. Nothing in this Section 2.19.11 shall either obligate the Administrative Agent to require the Borrower to deposit any funds in the Facility LC Collateral Account or limit the right of the Administrative Agent to release any funds held in the Facility LC Collateral Account in each case other than as required by Section 2.7.2 or Section 8.1.

2.19.12. Rights as a Lender. In its capacity as a Lender, the LC Issuer shall have the same rights and obligations as any other Lender.

2.20. Limitation of Interest; Applicability of Texas Finance Code Chapter 346.

(a) The Borrower, the Administrative Agent and the Lenders intend to strictly comply with all applicable laws, including applicable usury laws. Accordingly, the provisions of this Section 2.20 shall govern and control over every other provision of this Agreement or any other Loan Document which conflicts or is inconsistent with this Section 2.20, even if such provision declares that it controls. As used in this Section 2.20, the term “interest” includes the aggregate of all charges, fees, benefits or other compensation which constitute interest under applicable law, provided that, to the maximum extent permitted by applicable law, (a) any non-principal payment shall be characterized as an expense or as compensation for something other than the use, forbearance or detention of money and not as interest, and (b) all interest at any time contracted for, reserved, charged or received shall be amortized, prorated, allocated and spread, in equal parts during the full term of the Obligations. In no event shall the Borrower or any other Person be obligated to pay, or any Lender have any right or privilege to reserve, receive or retain, (a) any interest in excess of the maximum amount of nonusurious interest permitted under the applicable laws (if any) of the United States or of any other applicable state, or (b) total interest in excess of the amount which such Lender could lawfully have contracted for, reserved, received, retained or charged had the interest been calculated for the full term of the Obligations at the Highest Lawful Rate. On each day, if any, that the interest rate (the “Stated Rate”) called for under this Agreement or any other Loan Document exceeds the Highest Lawful Rate, the rate at which interest shall accrue shall automatically be fixed by operation of this sentence at the Highest Lawful Rate for that day, and shall remain fixed at the Highest Lawful Rate for each day thereafter until the total amount of interest accrued equals the total amount of interest which would have accrued if there were no such ceiling rate as is imposed by this sentence. Thereafter, interest shall accrue at the Stated Rate unless and until the Stated Rate again exceeds the Highest Lawful Rate when the provisions of the

immediately preceding sentence shall again automatically operate to limit the interest accrual rate. The daily interest rates to be used in calculating interest at the Highest Lawful Rate shall be determined by dividing the applicable Highest Lawful Rate per annum by the number of days in the calendar year for which such calculation is being made. None of the terms and provisions contained in this Agreement or in any other Loan Document which directly or indirectly relate to interest shall ever be construed without reference to this Section 2.20, or be construed to create a contract to pay for the use, forbearance or detention of money at an interest rate in excess of the Highest Lawful Rate. If the term of any Obligation is shortened by reason of acceleration of maturity as a result of any Default or by any other cause, or by reason of any required or permitted prepayment, and if for that (or any other) reason any Lender at any time, including but not limited to, the stated maturity, is owed or receives (and/or has received) interest in excess of interest calculated at the Highest Lawful Rate, then and in any such event all of any such excess interest shall be canceled automatically as of the date of such acceleration, prepayment or other event which produces the excess, and, if such excess interest has been paid to such Lender, it shall be credited pro tanto against the then-outstanding principal balance of the Borrower’s obligations to such Lender, effective as of the date or dates when the event occurs which causes it to be excess interest, until such excess is exhausted or all of such principal has been fully paid and satisfied, whichever occurs first, and any remaining balance of such excess shall be promptly refunded to its payor.

(b) Chapter 346 of the Texas Finance Code (which regulates certain revolving credit accounts (formerly Tex. Rev. Civ. Stat. Ann. Art. 5069, Ch. 15)) shall not apply to this Agreement or to any Loan, nor shall this Agreement or any Loan be governed by or be subject to the provisions of such Chapter 346 in any manner whatsoever.

2.21. Borrowing Base.

(i) Amount. For the period from and including the Closing Date to but not including the first Redetermination Date, the amount of the Borrowing Base shall be $200,000,000 (provided that the initial Aggregate Commitment shall be $150,000,000, until such time as the Borrower exercises its right to increase the Aggregate Commitment in accordance with Section 2.5(ii) or the Aggregate Commitments are otherwise adjusted in accordance with this Agreement). Notwithstanding the foregoing, the Borrowing Base will be subject to interim adjustments pursuant to either Section 6.1.8(iv) or Section 6.2.11.

(ii) Redetermination. On or before March 15th and September 15th of each year, commencing March 15, 2004, the Administrative Agent shall propose in writing to the Borrower and the Lenders a new Borrowing Base in accordance with Section 2.21(iii) (assuming receipt by the Administrative Agent of the Engineering Reports in a timely and complete manner). After having received notice of such proposal by the Administrative Agent, each Lender shall have fifteen (15) days to agree with such proposal or disagree by proposing an alternate Borrowing Base. If at the end of such fifteen (15) days, any Lender has not communicated its approval or disapproval, such silence shall be deemed to be an approval. If, however, at the end of such 15-day period, the Lenders or the Required Lenders, as applicable, have not approved or deemed to have approved, as aforesaid, the proposed Borrowing Base, then the Borrowing Base shall be

determined in accordance with Section 2.21(iv). After such redetermined Borrowing Base is approved by (a) all Lenders in the case of any increase in the Borrowing Base, (b) the Required Lenders in the case of any maintenance or any decrease in the Borrowing Base, or (c) as otherwise determined as provided in Section 2.21(iv), the Administrative Agent will notify the Borrower and the Lenders of the amount of the redetermined Borrowing Base, and such amount shall become effective and applicable to the Borrower, the Agents, the LC Issuer and the Lenders as of the next succeeding April 1st or October 1st, as applicable. Notwithstanding the foregoing, however, any increase in the Borrowing Base shall require approval or deemed approval of all the Lenders as set forth in this Section 2.21(ii).

(iii) Engineering Reports. Upon receipt of the Reserve Report and such other reports, data and supplemental information, including the information provided pursuant to Section 6.1.7(iii), as may, from time to time, be reasonably requested by the Required Lenders (the “Engineering Reports”), the Administrative Agent will evaluate such information. The Administrative Agent, with the approval or deemed approval of the Lenders as set forth in Section 2.21(ii), but subject to the terms of Section 2.21(ii), shall, in good faith, redetermine the Borrowing Base based upon such information and such other information (including, without limitation, information described in the Engineering Reports, the status of title with respect to the Oil and Gas Properties and the existence of any other Indebtedness) as the Administrative Agent deems appropriate and consistent with its normal oil and gas lending criteria as it exists at the particular time. Such redetermination shall be accomplished not later than and effective as of the first (1st) day of each April and October of each calendar year, assuming that the Borrower shall have furnished the Engineering Reports in a timely and complete manner as required by Section 6.1.7. In assessing whether to approve or reject a proposed Borrowing Base, each Lender will assess, in good faith, the Engineering Reports and the other information as they deem appropriate and consistent with its respective oil and gas lending criteria and procedures as they exist at the particular time.

(iv) Consensus and Failure of Consensus. Except as hereinafter provided, the decision of the Lenders or Required Lenders, as applicable, with respect to any Borrowing Base determination shall control; provided, however, if the Lenders or Required Lenders, as applicable, have not approved or are not deemed to have approved the Borrowing Base as of the date such a determination is called for in Section 2.21(ii), the Administrative Agent shall determine the weighted arithmetic average of the Borrowing Bases determined by each Lender or each of the Required Lenders, as applicable, (weighted in accordance with each such Lender’s Pro Rata Share) for purposes of this Section 2.21 and such amount shall then become the Borrowing Base until the next Scheduled Redetermination Date or the next date on which an interim redetermination occurs under Section 2.21(v) or the next adjustment under either Section 6.1.8(iv) or Section 6.2.11. Notwithstanding the foregoing, however, any increase in the Borrowing Base shall require approval or deemed approval of all the Lenders as set forth in Section 2.21(ii).

(v) Interim Redeterminations. The Borrower may, at its option, one time during any 12-month period initiate an interim redetermination of the Borrowing Base. In addition, the Borrower may, at its option, in connection with any acquisition (or any series of acquisitions occurring since the most recent redetermination of the Borrowing Base) by the Borrower or a Restricted Subsidiary of Oil and Gas Properties having a purchase price, either individually or in

the aggregate, of $50,000,000 or more, initiate an interim redetermination of the Borrowing Base. The Administrative Agent (at the direction of the Required Lenders, in their option) may one time during any 12-month period initiate an interim redetermination of the Borrowing Base. The Borrowing Base also may be redetermined in accordance with Section 6.2.10(i).

ARTICLE III

YIELD PROTECTION; TAXES

3.1. Yield Protection. If, on or after the date of this Agreement, the adoption of any law or any governmental or quasi-governmental rule, regulation, policy, guideline or directive (whether or not having the force of law), or any change in the interpretation or administration thereof by any governmental or quasi-governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Lender or applicable Lending Installation or the LC Issuer with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency:

(i) subjects any Lender or any applicable Lending Installation or the LC Issuer to any Taxes, or changes the basis of taxation of payments (other than with respect to Excluded Taxes) to any Lender or the LC Issuer in respect of its Eurodollar Loans, Facility LCs or participations therein, or

(ii) imposes or increases or deems applicable any reserve, assessment, insurance charge, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender or any applicable Lending Installation or the LC Issuer (other than reserves and assessments taken into account in determining the interest rate applicable to Eurodollar Advances), or

(iii) imposes any other condition the result of which is to increase the cost to any Lender or any applicable Lending Installation or the LC Issuer of making, funding or maintaining its Eurodollar Loans, or of issuing or participating in Facility LCs or reduces any amount receivable by any Lender or any applicable Lending Installation or the LC Issuer in connection with its Eurodollar Loans or Facility LC or participation therein, or requires any Lender or any applicable Lending Installation or the LC Issuer to make any payment calculated by reference to the amount of Eurodollar Loans, Facility LCs or participations therein held or interest or LC Fees received by it, by an amount deemed material by such Lender or the LC Issuer, as the case may be,

and the result of any of the foregoing is to increase the cost to such Lender or applicable Lending Installation or the LC Issuer, as the case may be, of making or maintaining its Eurodollar Loans or Commitment or of issuing or participating in Facility LCs or to reduce the return received by such Lender or applicable Lending Installation or the LC Issuer, as the case may be, in connection with such Eurodollar Loans, Commitment, Facility LCs or participations therein, then, within 15 days of demand by such Lender or the LC Issuer, as the case may be, the Borrower shall pay such Lender or the LC Issuer, as the case may be, such additional amount or amounts as will compensate such Lender or the LC Issuer, as the case may be, for such increased cost or reduction in amount received.

3.2. Changes in Capital Adequacy Regulations. If a Lender or the LC Issuer determines the amount of capital required or expected to be maintained by such Lender or the LC Issuer, any Lending Installation of such Lender or the LC Issuer, or any corporation controlling such Lender or the LC Issuer is increased as a result of a Change, then, within 15 days of demand by such Lender or the LC Issuer, the Borrower shall pay such Lender or the LC Issuer the amount necessary to compensate for any shortfall in the rate of return on the portion of such increased capital which such Lender or the LC Issuer determines is attributable to this Agreement, its Outstanding Credit Exposure or its Commitment to make Loans and issue or participate in Facility LCs, as the case may be, hereunder (after taking into account such Lender’s or the LC Issuer’s policies as to capital adequacy). “Change” means (i) any change after the date of this Agreement in the Risk-Based Capital Guidelines or (ii) any adoption of or change in any other law, governmental or quasi-governmental rule, regulation, policy, guideline, interpretation, or directive (whether or not having the force of law) after the date of this Agreement which affects the amount of capital required or expected to be maintained by any Lender or the LC Issuer or any Lending Installation or any corporation controlling any Lender or the LC Issuer. “Risk-Based Capital Guidelines” means (i) the risk-based capital guidelines in effect in the United States on the date of this Agreement, including transition rules, and (ii) the corresponding capital regulations promulgated by regulatory authorities outside the United States implementing the July 1988 report of the Basle Committee on Banking Regulation and Supervisory Practices Entitled “International Convergence of Capital Measurements and Capital Standards,” including transition rules, and any amendments to such regulations adopted prior to the date of this Agreement.

3.3. Availability of Types of Advances. If any Lender determines that maintenance of its Eurodollar Loans at a suitable Lending Installation would violate any applicable law, rule, regulation, or directive, whether or not having the force of law, or if the Required Lenders determine that (i) deposits of a type and maturity appropriate to match fund Eurodollar Advances are not available or (ii) the interest rate applicable to Eurodollar Advances does not accurately reflect the cost of making or maintaining Eurodollar Advances, then the Administrative Agent shall suspend the availability of Eurodollar Advances and require any affected Eurodollar Advances to be repaid or converted to Floating Rate Advances, subject to the payment of any funding indemnification amounts required by Section 3.4.

3.4. Funding Indemnification. If any payment of a Eurodollar Advance occurs on a date which is not the last day of the applicable Interest Period, whether because of acceleration, prepayment or otherwise, or a Eurodollar Advance is not made on the date specified by the Borrower for any reason other than default by the Lenders, the Borrower will indemnify each Lender for any loss or cost incurred by it resulting therefrom, including, without limitation, any loss or cost in liquidating or employing deposits acquired to fund or maintain such Eurodollar Advance.

3.5. Taxes. (i) All payments by the Borrower to or for the account of any Lender, the LC Issuer or the Administrative Agent hereunder or under any Note or Facility LC Application shall be made free and clear of and without deduction for any and all Taxes. If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder to any Lender, the LC Issuer or the Administrative Agent, (a) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to

additional sums payable under this Section 3.5) such Lender, the LC Issuer or the Administrative Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (b) the Borrower shall make such deductions, (c) the Borrower shall pay the full amount deducted to the relevant authority in accordance with applicable law and (d) the Borrower shall furnish to the Administrative Agent the original copy of a receipt evidencing payment thereof within 30 days after such payment is made.

(ii) In addition, the Borrower hereby agrees to pay any present or future stamp or documentary taxes and any other excise or property taxes, charges or similar levies which arise from any payment made hereunder or under any Note or Facility LC Application or from the execution or delivery of, or otherwise with respect to, this Agreement or any Note or Facility LC Application (“Other Taxes”).

(iii) The Borrower hereby agrees to indemnify the Administrative Agent, the LC Issuer and each Lender for the full amount of Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes imposed on amounts payable under this Section 3.5) paid by the Administrative Agent, the LC Issuer or such Lender as a result of its Commitment, any Loans made by it hereunder, any Facility LC issued or participated in, or otherwise, in connection with its participation in this Agreement and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto. Payments due under this indemnification shall be made within 30 days of the date the Administrative Agent, the LC Issuer or such Lender makes demand therefor pursuant to Section 3.6.

(iv) Each Lender that is not incorporated under the laws of the United States of America or a state thereof (each a “Non-U.S. Lender”) agrees that it will, not more than ten Business Days after the date of this Agreement, (a) deliver to the Administrative Agent two duly completed copies of United States Internal Revenue Service Form W-8BEN or W-8ECI, certifying in either case that such Lender is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes, and (b) deliver to the Administrative Agent a United States Internal Revenue Form W-8 or W-9, as the case may be, and certify that it is entitled to an exemption from United States backup withholding tax. Each Non-U.S. Lender further undertakes to deliver to each of the Borrower and the Administrative Agent (x) renewals or additional copies of such form (or any successor form) on or before the date that such form expires or becomes obsolete, and (y) after the occurrence of any event requiring a change in the most recent forms so delivered by it, such additional forms or amendments thereto as may be reasonably requested by the Borrower or the Administrative Agent. All forms or amendments described in the preceding sentence shall certify that such Lender is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes, unless an event (including without limitation any change in treaty, law or regulation) has occurred prior to the date on which any such delivery would otherwise be required which renders all such forms inapplicable or which would prevent such Lender from duly completing and delivering any such form or amendment with respect to it and such Lender advises the Borrower and the Administrative Agent that it is not capable of receiving payments without any deduction or withholding of United States federal income tax.

(v) For any period during which a Non-U.S. Lender has failed to provide the Borrower with an appropriate form pursuant to clause (iv), above (unless such failure is due to a

change in treaty, law or regulation, or any change in the interpretation or administration thereof by any governmental authority, occurring subsequent to the date on which a form originally was required to be provided), such Non-U.S. Lender shall not be entitled to indemnification under this Section 3.5 with respect to Taxes imposed by the United States.

(vi) Any Lender that is entitled to an exemption from or reduction of withholding tax with respect to payments under this Agreement or any Note pursuant to the law of any relevant jurisdiction or any treaty shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law as will permit such payments to be made without withholding or at a reduced rate.

(vii) If the U.S. Internal Revenue Service or any other governmental authority of the United States or any other country or any political subdivision thereof asserts a claim that the Administrative Agent did not properly withhold tax from amounts paid to or for the account of any Lender (because the appropriate form was not delivered or properly completed, because such Lender failed to notify the Administrative Agent of a change in circumstances which rendered its exemption from withholding ineffective, or for any other reason), such Lender shall indemnify the Administrative Agent fully for all amounts paid, directly or indirectly, by the Administrative Agent as tax, withholding therefor, or otherwise, including penalties and interest, and including taxes imposed by any jurisdiction on amounts payable to the Administrative Agent under this subsection, together with all costs and expenses related thereto (including attorneys fees and time charges of attorneys for the Administrative Agent, which attorneys may be employees of the Administrative Agent). The obligations of the Lenders under this Section 3.5(vii) shall survive the payment of the Obligations and termination of this Agreement.

3.6. Lender Statements; Survival of Indemnity. To the extent reasonably possible, each Lender shall designate an alternate Lending Installation with respect to its Eurodollar Loans to reduce any liability of the Borrower to such Lender under Sections 3.1, 3.2 and 3.5 or to avoid the unavailability of Eurodollar Advances under Section 3.3, so long as such designation is not, in the judgment of such Lender, disadvantageous to such Lender. Each Lender shall deliver a written statement of such Lender to the Borrower (with a copy to the Administrative Agent) as to the amount due, if any, under Section 3.1, 3.2, 3.4 or 3.5. Such written statement shall set forth in reasonable detail the calculations upon which such Lender determined such amount and shall be final, conclusive and binding on the Borrower in the absence of manifest error. Determination of amounts payable under such Sections in connection with a Eurodollar Loan shall be calculated as though each Lender funded its Eurodollar Loan through the purchase of a deposit of the type and maturity corresponding to the deposit used as a reference in determining the Eurodollar Rate applicable to such Loan, whether in fact that is the case or not. Unless otherwise provided herein, the amount specified in the written statement of any Lender shall be payable on demand after receipt by the Borrower of such written statement. The obligations of the Borrower under Section 3.1, 3.2, 3.4 and 3.5 shall survive payment of the Obligations and termination of this Agreement.

3.7. Time Limit; Etc.

(i) Time Limit. Notwithstanding anything to the contrary contained in Sections 3.1 through 3.6, the Borrower shall not be required to reimburse or pay any costs or expenses to any Lender as required by such Sections that have accrued more than 180 days prior to such Lender’s giving notice to the Borrower that such Lender has suffered or incurred such costs or expenses.

(ii) Non-Discriminatory Basis. None of the Lenders shall be permitted to pass through to the Borrower costs and expenses under Sections 3.1 through 3.6 on a discriminatory basis (i.e. which are not also passed through by such Lender to other customers of such Lender similarly situated when such customer is subject to documents containing similar provisions as those contained in such Sections).

There are no statements or conclusions in any Reserve Report which are based upon or include misleading information or fail to take into account material information regarding the matters reported therein, it being understood that each Reserve Report is necessarily based upon professional opinions, estimates and projections and that Borrower does not warrant that such opinions, estimates and projections will ultimately prove to have been accurate.

No Default hereunder has occurred and is continuing.

(ii) On or before the delivery to the Administrative Agent and the Lenders of each Reserve Report required by Section 6.1.7(i), the Borrower will deliver title information in form and substance acceptable to the Administrative Agent covering enough of the Oil and Gas Properties evaluated by such Reserve Report that were not included in the immediately preceding Reserve Report, so that the Administrative Agent shall have received together with title information previously delivered to the Administrative Agent, satisfactory title information on at least 60% of the value of the Oil and Gas Properties evaluated by such Reserve Report.

(iii) If the Borrower has provided title information for additional Properties under Section 6.1.8(ii), the Borrower shall, within 60 days of notice from the Administrative Agent that title defects or exceptions exist with respect to such additional Properties, either (i) cure any such title defects or exceptions (including defects or exceptions as to priority) which are not permitted by Section 6.2.3 raised by such information, (ii) substitute acceptable Mortgaged Properties with no title defects or exceptions (except for Excepted Liens) having an equivalent value or (iii) deliver title information in form and substance acceptable to the Administrative Agent so that the Administrative Agent shall have received, together with title information previously delivered to the Administrative Agent, satisfactory title information on at least 60% of the value of the Oil and Gas Properties evaluated by such Reserve Report.

To the extent that the Administrative Agent or the Lenders are not satisfied with title to any Mortgaged Property after the 60-day period has elapsed, such unacceptable Mortgaged Property shall not count towards the 60% requirement,

and the Administrative Agent may send a notice to the Borrower and the Lenders that the then outstanding Borrowing Base shall be reduced by an amount as determined by the Majority Lenders to cause the Borrower to be in compliance with the requirement to provide acceptable title information on 60% of the value of the Oil and Gas Properties evaluated in the most recent Reserve Report.

In the event that the Mortgaged Properties do not represent at least the lesser or (i) 75% of such total value or (ii) 125% of the Aggregate Commitment, then the Borrower shall, and shall cause its Restricted Subsidiaries to, grant to the Administrative Agent as security for the Obligations a first-priority Lien interest (subject only to Excepted Liens of the type described in clauses (i) to (v), (vii) and (viii) of the definition thereof) on additional Oil and Gas Properties not already subject to a Lien of the Collateral Documents such that after giving effect thereto, the Mortgaged Properties will represent at least the lesser of (i) 75% of such total value or (ii) 125% of the Aggregate Commitment. All such Liens will be created and perfected by and in accordance with the provisions of mortgages, deeds of trust, security agreements and financing statements, or other Collateral Documents, all in form and substance reasonably satisfactory to the Administrative Agent and in sufficient executed (and acknowledged where necessary or appropriate) counterparts for recording purposes. In order to comply with the foregoing, if any Restricted Subsidiary places a Lien on its Oil and Gas Properties and such Restricted Subsidiary is not a Guarantor, then it shall become a Guarantor and comply with Section 6.1.9(ii).

6.2.10. Mergers, Etc. Neither the Borrower nor any Restricted Subsidiary will merge into or with or consolidate with any other Person, or sell, lease or otherwise dispose of (whether in one transaction or in a series of transactions) all or substantially all of its Property or assets to any other Person (any such transaction, a “consolidation”); provided that

(i) the Borrower or any Restricted Subsidiary may participate in a consolidation with any other Person; provided that (a) no Default or Unmatured Default is continuing, (b) any such consolidation would not cause a Default or Unmatured Default hereunder, (c) if the Borrower consolidates with any Person, the Borrower shall be the surviving Person, (d) if any Restricted Subsidiary consolidates with any Person (other than the Borrower or a Restricted Subsidiary) and such Restricted Subsidiary is not the surviving Person, such surviving Person shall expressly assume in writing (in form and substance satisfactory to the Administrative Agent) all obligations of such Restricted Subsidiary under the Loan Documents and (e) the Borrowing Base will be redetermined in accordance with Section 2.21; and

(ii) any Restricted Subsidiary may participate in a consolidation with the Borrower (provided that the Borrower shall be the continuing or surviving corporation) or any other Restricted Subsidiary (provided that the surviving entity shall be a Restricted Subsidiary).

6.2.11. Sale of Oil and Gas Properties. The Borrower will not, and will not permit any Restricted Subsidiary to, sell, assign, farm-out, convey or otherwise transfer any Oil and Gas Property or any interest in any Oil and Gas Property except for (i) the sale of Hydrocarbons in the ordinary course of business; (ii) farmouts of undeveloped acreage and assignments in connection with such farmouts; (iii) the sale or transfer of equipment that is no longer necessary for the business of the Borrower or such Restricted Subsidiary or is replaced by equipment of at least comparable value and use; (iv) the sale, transfer or other disposition of equity interests in Unrestricted Subsidiaries; (v) the sale, transfer or other disposition of the Oil and Gas Properties described on Schedule 6.2.11 - West Texas Asset Disposition; and (vi) sales or other dispositions (including Casualty Events and dispositions resulting from the exercise of eminent domain, condemnation or nationalization) of Oil and Gas Properties or any interest therein or, with the prior written consent of the Required Lenders, all capital stock or other

equity interests in Restricted Subsidiaries owning Oil and Gas Properties; provided that such sales or other dispositions of Oil and Gas Properties or of Restricted Subsidiaries owning Oil and Gas Properties included in the most recently delivered Reserve Report during any period between two successive Scheduled Redetermination Dates having a fair market value in excess of $15,000,000, individually or in the aggregate, shall result in an adjustment to the Borrowing Base in an amount equal to the value, if any, assigned such Property by the Required Lenders in good faith as provided in Section 2.21(ii); and provided further that if any such sale or other disposition is of a Restricted Subsidiary owning Oil and Gas Properties, such sale or other disposition shall include all the capital stock of such Restricted Subsidiary. To determine the amount by which the Borrowing Base shall be adjusted, the Borrower shall give the Administrative Agent and the Lenders notice of the proposed sale or other disposition not less than ten (10) days prior to the date of the proposed sale or other disposition. The Administrative Agent shall, in good faith and utilizing the Engineering Reports delivered in connection with the most recent redetermination of the Borrowing Base (or the initial determination, as applicable), propose to the Lenders a reduction to the Borrowing Base to reflect the value of the Properties being sold or otherwise disposed of. Thereafter, the Lenders shall have five (5) days to approve or object to such proposed amount; and any failure to object shall be deemed to be an approval. In the event there is no approval or deemed approval, the Administrative Agent shall poll the Lenders to ascertain the lowest reduction to the Borrowing Base then acceptable to a number of Lenders sufficient to constitute the Required Lenders for purposes of this Section 6.2.11 and such amount shall then be the allocated value of the Property subject to such sale or disposition.

6.2.12. Environmental Matters. Neither the Borrower nor any Restricted Subsidiary will cause or permit any of its Property to be in violation of, or do anything or permit anything to be done which will subject any such Property to any remedial obligations under any Environmental Laws, assuming disclosure to the applicable Governmental Authority of all relevant facts, conditions and circumstances, if any, pertaining to such Property where such violations or remedial obligations could reasonably be expected to result in an Environmental Liability to the Borrower or any of its Restricted Subsidiaries in excess of $4,000,000.

6.2.13. Transactions with Affiliates. Neither the Borrower nor any Restricted Subsidiary will enter into any transaction, including, without limitation, any purchase, sale, lease or exchange of Property or the rendering of any service, with any Affiliate (other than the Guarantors and wholly-owned Subsidiaries of the Borrower) unless such transactions are otherwise permitted under this Agreement and are upon fair and reasonable terms no less favorable to it than it would obtain in a comparable arm’s length transaction with a Person not an Affiliate.

6.2.14. Subsidiaries. The Borrower shall not, and shall not permit any Restricted Subsidiary to, create or acquire any additional Restricted Subsidiary or redesignate an Unrestricted Subsidiary as a Restricted Subsidiary unless the Borrower complies with Section 6.1.9(ii). The Borrower shall not, and shall not permit any Restricted Subsidiary to, sell, assign or otherwise dispose of any capital stock in any Restricted Subsidiary except in compliance with Section 6.2.11(vi).

6.2.15. Negative Pledge Agreements. Neither the Borrower nor any Restricted Subsidiary will create, incur, assume or suffer to exist any contract, agreement or understanding

(other than this Agreement, the Collateral Documents, instruments governing Indebtedness permitted under Section 6.2.2(viii) or other instruments creating Liens permitted by Section 6.2.3(iii) and (v)) which in any way prohibits or restricts the granting, conveying, creation or imposition of any Lien on any of its Property in favor of the Agents, the LC Issuer and the Lenders or restricts any Restricted Subsidiary from paying dividends to the Borrower, or which requires the consent of or notice to other Persons in connection therewith.

6.2.16. Gas Imbalances, Take-or-Pay or Other Prepayments. The Borrower will not allow gas imbalances, take-or-pay or other prepayments with respect to the Oil and Gas Properties of the Borrower and its Restricted Subsidiaries that would require the Borrower or its Restricted Subsidiaries to deliver Hydrocarbons produced on Oil and Gas Properties at some future time without then or thereafter receiving full payment therefor in excess of two (2) Bcf of gas (or its equivalent) in the aggregate on a net basis for the Borrower and its Restricted Subsidiaries.

6.2.17. Fiscal Year; Fiscal Quarter. The Borrower shall not, and shall not permit any of its Subsidiaries to, change its Fiscal Year or any of its Fiscal Quarters.

6.2.18. Rate Management Transactions. The Borrower will not enter into, and the Borrower will not permit any of its Restricted Subsidiaries to enter into, any Rate Management Transactions in respect of Hydrocarbons which would cause the amount of Hydrocarbons which are the subject of Rate Management Transactions in existence at such time to exceed either (i) eighty percent (80%) of the Borrower’s and its Restricted Subsidiaries’ projected production from Proved Hydrocarbon Reserves during the term of such existing Rate Management Transactions as set forth on the most current Reserve Report or (ii) ninety percent (90%) of the Borrower’s and its Restricted Subsidiaries’ projected production from Proved Developed Producing Hydrocarbon Reserves during the term of such existing Rate Management Transactions as set forth on the most current Reserve Report. The Borrower will not, and the Borrower will not permit any of its Restricted Subsidiaries to, post letters of credit to secure obligations under Rate Management Transactions which, when added to the amount of cash and other securities pledged under Section 6.2.3(iv) exceeds $7,500,000 in aggregate for all such Rate Management Transactions. For purposes of this Section 6.2.18, forecasts of projected production shall equal the projections for Proved Hydrocarbon Reserves or Proved Developed Producing Hydrocarbon Reserves, as applicable, set out in the most recent Reserve Report as revised to account for any increase or decrease therein anticipated because of information obtained by Borrower subsequent to the publication of the most recent Reserve Report including the Borrower’s internal forecasts of production decline rates for existing wells and additions to or deletions from anticipated future production from new wells and acquisitions coming on stream or failing to come on stream.

6.2.19. Restricted Subsidiaries. Except as permitted by Sections 6.2.10 and 6.2.11(vi), at all times, the Borrower shall directly or indirectly through a wholly-owned Restricted Subsidiary retain full, absolute and unencumbered title to all of the issued and outstanding stock or other ownership interests in each Restricted Subsidiary.

ARTICLE VIII

ACCELERATION, WAIVERS, AMENDMENTS AND REMEDIES

8.1. Acceleration; Facility LC Collateral Amount. (i) If any Default described in Section 7.1(vi) or Section 7.1(vii) occurs with respect to the Borrower or any Guarantor, the obligations of the Lenders to make Loans hereunder and the obligation and power of the LC Issuer to issue Facility LCs shall automatically terminate and the Obligations shall immediately become due and payable without any election or action on the part of the Administrative Agent, the LC Issuer or any Lender and the Borrower will be and become thereby unconditionally obligated, without any further notice, act presentment, demand, protest, notice of intent to accelerate, notice of acceleration or other formalities of any kind, all of which are hereby expressly waived by the Borrower, to pay to the Administrative Agent an amount in immediately available funds, which funds shall be held in the Facility LC Collateral Account, equal to the difference of (x) the amount of LC Obligations at such time, less (y) the amount on deposit in the Facility LC Collateral Account at such time which is free and clear of all rights and claims of third parties and has not been applied against the Obligations (such difference, the “Collateral Shortfall Amount”). If any other Default occurs, the Required Lenders (or the Administrative Agent with the consent of the Required Lenders) may (a) terminate or suspend the obligations of the Lenders to make Loans hereunder and the obligation and power of the LC Issuer to issue Facility LCs, or declare the Obligations to be due and payable, or both, whereupon the Obligations shall become immediately due and payable, without presentment, demand, protest, notice of intent to accelerate, notice of acceleration or other formalities of any kind, all of which are hereby expressly waived by the Borrower, and (b) upon notice to the Borrower and in addition to the continuing right to demand payment of all Obligations, make demand on the Borrower to pay, and the Borrower will, forthwith upon such demand and without any further notice or act, pay to the Administrative Agent the Collateral Shortfall Amount, which funds shall be deposited in the Facility LC Collateral Account.

(ii) If at any time while any Default is continuing, the Administrative Agent determines that the Collateral Shortfall Amount at such time is greater than zero, the Administrative Agent may make demand on the Borrower to pay, and the Borrower will, forthwith upon such demand and without any further notice or act, pay to the Administrative Agent the Collateral Shortfall Amount, which funds shall be deposited in the Facility LC Collateral Account.

(iii) The Administrative Agent may at any time or from time to time after funds are deposited in the Facility LC Collateral Account, apply such funds to the payment of the Obligations and any other amounts as shall from time to time have become due and payable by the Borrower to the Lenders or the LC Issuer under the Loan Documents.

(iv) At any time while any Default is continuing, neither the Borrower nor any Person claiming on behalf of or through the Borrower shall have any right to withdraw any of the funds held in the Facility LC Collateral Account. After all of the Obligations have been indefeasibly paid in full and the Aggregate Commitment has been terminated, any funds remaining in the Facility LC Collateral Account shall be returned by the Administrative Agent to the Borrower or paid to whomever may be legally entitled thereto at such time.

(v) If, within thirty (30) days after acceleration of the maturity of the Obligations or termination of the obligations (subject to the conditions of this Agreement) of the Lenders to make Loans and the obligation and power of the LC Issuer to issue Facility LCs hereunder as a result of any Default (other than any Default as described in Section 7.1(vi) or Section 7.1(vii) with respect to the Borrower) and before any judgment or decree for the payment of the Obligations due shall have been obtained or entered, the Required Lenders (in their sole discretion) shall so direct, the Administrative Agent shall, by notice to the Borrower, rescind and annul such acceleration and/or termination.

(vi) In the case of the occurrence of a Default, the Administrative Agent, the LC Issuer and the Lenders will have all other rights and remedies available at law and equity.

8.2. Amendments. Subject to the provisions of this Section 8.2, the Required Lenders (or the Administrative Agent with the consent in writing of the Required Lenders) and the Borrower may enter into agreements supplemental hereto for the purpose of adding or modifying any provisions to the Loan Documents or changing in any manner the rights of the Lenders or the Borrower hereunder or waiving any Default hereunder; provided, however, that no such supplemental agreement shall: (i) without the consent of all of the Lenders, (a) extend the final maturity of any Loan, or extend the expiry date of any Facility LC to a date after the Facility Termination Date, or postpone any regularly scheduled payment or date for mandatory prepayment of principal of any Loan or forgive all or any portion of the principal amount thereof or any Reimbursement Obligation related thereto, or reduce the rate or extend the time of payment of interest or fees thereon or Reimbursement Obligations related thereto; (b) forgive the principal amount of any Obligation under this Agreement or any other Loan Document; (c) reduce the interest rate applicable to the Loans or the fees payable to the Lenders generally; (d) reduce either percentage set forth in Section 6.1.9 to less than 75% or 125%, respectively; (e) reduce the percentage specified in the definition of Required Lenders; (f) increase the Borrowing Base; (g) modify Section 2.21; (h) amend this Section 8.2 or Section 12.3 or any related definitions contained in Section 1.1; (i) except as provided in the Collateral Documents, release any Guarantor or release all or substantially all of the Collateral (other than as provided in Section 10.16); or (j) permit the Borrower to assign its rights under this Agreement; or (ii) increase the amount of the Commitment of any Lender hereunder without the consent of such Lender.

No amendment, modification or waiver of any provision of this Agreement which modifies the rights, duties or obligations of, or which otherwise relates to, any Agent shall be effective without the written consent of such Agent, and no amendment, modification or waiver of any provision which modifies the rights, duties or obligations of, or which otherwise relates to, the LC Issuer shall be effective without the written consent of the LC Issuer. The Administrative Agent may waive payment of the fee required under Section 12.3.3 without obtaining the consent of any other party to this Agreement. Any supplement to Schedule 5.14 (Subsidiaries) shall be effective simply by delivering to the Administrative Agent a supplemental schedule clearly marked as such and, upon receipt, the Administrative Agent will promptly deliver a copy thereof to the Lenders.

8.3. Preservation of Rights. No delay or omission of the Lenders, the LC Issuer or the Administrative Agent in the exercise of any right under the Loan Documents shall impair such

right or be construed to be a waiver of any Default or an acquiescence therein, and the making of a Credit Extension notwithstanding the existence of a Default or the inability of the Borrower to satisfy the conditions precedent to such Credit Extension shall not constitute any waiver or acquiescence. Any single or partial exercise of any such right shall not preclude other or further exercise thereof or the exercise of any other right, and no waiver, amendment or other variation of the terms, conditions or provisions of the Loan Documents whatsoever shall be valid unless in writing signed by the Lenders required pursuant to Section 8.2, and then only to the extent in such writing specifically set forth. All remedies contained in the Loan Documents or by law afforded shall be cumulative and all shall be available to the Agents, the LC Issuer and the Lenders until the Obligations have been paid in full.

8.4. Application of Payments. Any amount received by the Administrative Agent from the exercise of any rights or remedies hereunder or under any of the Collateral Documents shall be applied by the Administrative Agent to payment of the Obligations in the following order unless a court of competent jurisdiction shall otherwise direct:

(a) FIRST, to payment of all reasonable costs and expenses of the Administrative Agent incurred in connection with the collection and enforcement of the Obligations or of any security interest granted to the Administrative Agent in connection with any collateral securing the Obligations;

(b) SECOND, to payment of that portion of the Obligations constituting accrued and unpaid interest and fees, pro rata among the Lenders and their Affiliates in accordance with the amount of such accrued and unpaid interest and fees owing to each of them;

(c) THIRD, to payment of the principal of the Obligations and the net early termination payments and any other Lender Party Rate Management Obligations then due and unpaid from the Borrower to any of the Lenders or their Affiliates, pro rata among the Lenders and their Affiliates in accordance with the amount of such principal and such net early termination payments and other Lender Party Rate Management Obligations then due and unpaid owing to each of them;

(d) FOURTH, to payment of any Obligations (other than those listed above) pro rata among those parties to whom such Obligations are due in accordance with the amounts owing to each of them; and

(e) FIFTH, any surplus thereafter remaining shall be paid to the Borrower or it successor or assigns as its or their interests shall appear.

The failure of any Lender to perform any of its obligations hereunder shall not relieve any other Lender from any of its obligations hereunder. This Agreement shall not be construed so as to confer any right or benefit upon any Person other than the parties to this Agreement and their respective successors and assigns, provided, however, that the parties hereto expressly agree that the Co-Lead Arrangers shall enjoy the benefits of the provisions of Sections 9.6, 9.10 and 10.11 to the extent specifically set forth therein and shall have the right to enforce such provisions on its own behalf and in its own name to the same extent as if it were a party to this Agreement.

9.6. Expenses; Indemnification. (i) The Borrower shall reimburse the Administrative Agent, the LC Issuer and the Co-Lead Arrangers for any costs, internal charges and out-of-pocket expenses (including attorneys’ fees and time charges of attorneys for the Administrative Agent), paid or incurred by the Administrative Agent, the LC Issuer or the Co-Lead Arrangers in connection with the preparation, negotiation, execution, delivery, syndication, distribution (including, without limitation, via the internet), review, amendment, modification, and administration of the Loan Documents. The Borrower also agrees to reimburse the Agents, the Co-Lead Arrangers, the LC Issuer and the Lenders for any costs, internal charges and out-of-pocket expenses (including attorneys’ fees and time charges of attorneys for such Agent, the Co-Lead Arrangers, the LC Issuer and the Lenders), paid or incurred by such Agent, the Co-Lead Arrangers, the LC Issuer or any Lender in connection with the preservation of rights under, enforcement of, and refinancing, renegotiation or restructuring of, the Loan Documents and any amendment, waiver or consent related thereto and to satisfy any obligation of the Borrower under this Agreement or any Loan Document, including, without limitation, all costs and expenses of foreclosure. Expenses being reimbursed by the Borrower under this Section include, without limitation, costs and expenses incurred in connection with the Reports described in the following sentence.

(ii) The Borrower hereby further agrees to indemnify the Agents, the Co-Lead Arrangers, the LC Issuer, each Lender, their respective Affiliates, and each of their directors, officers and employees (the “Indemnified Parties”) against all losses, claims, damages, penalties, judgments, liabilities and expenses (including, without limitation, all expenses of litigation or preparation therefor whether or not such Agent, the Co-Lead Arrangers, the LC Issuer, any Lender or any affiliate is a party thereto) which any of them may pay or incur arising out of or relating to this Agreement, the other Loan Documents, the transactions contemplated hereby or the direct or indirect application or proposed application of the proceeds of any Credit Extension hereunder except to the extent that they are determined in a final non-appealable judgment by a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of the party seeking indemnification; PROVIDED THAT IT IS THE INTENTION OF THE PARTIES HERETO THAT THE INDEMNIFIED PARTIES BE INDEMNIFIED IN THE CASE OF THEIR OWN NEGLIGENCE, REGARDLESS OF WHETHER SUCH NEGLIGENCE IS SOLE OR CONTRIBUTORY, ACTIVE OR PASSIVE, IMPUTED, JOINT OR TECHNICAL. The obligations of the Borrower under this Section 9.6 shall survive the termination of this Agreement.

9.7. Numbers of Documents. All statements, notices, closing documents, and requests hereunder shall be furnished to the Administrative Agent with sufficient counterparts so that the Administrative Agent may furnish one to each of the Lenders.

9.8. Accounting. Except as provided to the contrary herein, all accounting terms used herein shall be interpreted and all accounting determinations hereunder shall be made in accordance with GAAP.

9.9. Severability of Provisions. Any provision in any Loan Document that is held to be inoperative, unenforceable, or invalid in any jurisdiction shall, as to that jurisdiction, be inoperative, unenforceable, or invalid without affecting the remaining provisions in that jurisdiction or the operation, enforceability, or validity of that provision in any other jurisdiction, and to this end the provisions of all Loan Documents are declared to be severable.

9.10. Nonliability of Lenders. The relationship between the Borrower on the one hand and the Lenders, the LC Issuer and the Administrative Agent on the other hand shall be solely that of borrower and lender. Neither the Agents, the Co-Lead Arrangers, the LC Issuer nor any Lender shall have any fiduciary responsibilities to the Borrower or any of its Subsidiaries. None of the Agents, the Co-Lead Arrangers, the LC Issuer nor any Lender undertakes any responsibility to the Borrowers to review or inform the Borrower of any matter in connection with any phase of the Borrower’s or such Subsidiary’s business or operations. The Borrower agrees that none of the Agents, the Co-Lead Arrangers, the LC Issuer nor any Lender shall have liability to the Borrower or any of its Subsidiaries (whether sounding in tort, contract or otherwise) for losses suffered by the Borrower or any of its Subsidiaries in connection with, arising out of, or in any way related to, the transactions contemplated and the relationship established by the Loan Documents, or any act, omission or event occurring in connection therewith, unless it is determined in a final non-appealable judgment by a court of competent

jurisdiction that such losses resulted from the gross negligence or willful misconduct of the party from which recovery is sought. None of the Agents, the Co-Lead Arrangers, the LC Issuer nor any Lender shall have any liability with respect to, and the Borrower hereby waives, releases and agrees not to sue for, any special, indirect, consequential or punitive damages suffered by the Borrower or any of its Subsidiaries in connection with, arising out of, or in any way related to the Loan Documents or the transactions contemplated thereby.

9.11. Confidentiality. Each Lender agrees to hold any confidential information which it may receive from the Borrower or any of its Restricted Subsidiaries pursuant to this Agreement or the other Loan Documents in confidence, except for disclosure (i) to its Affiliates and to other Lenders and their respective Affiliates, (ii) to legal counsel, accountants, and other professional advisors to such Lender or to a Transferee, (iii) to regulatory officials, (iv) to any Person as requested pursuant to or as required by law, regulation, or legal process, (v) to any Person in connection with any legal proceeding to which such Lender is a party, (vi) to such Lender’s direct or indirect contractual counterparties in swap agreements or to legal counsel, accountants and other professional advisors to such counterparties, (vii) permitted by Section 12.4 and (viii) to rating agencies if requested or required by such agencies in connection with a rating relating to the Advances hereunder. Notwithstanding anything to the contrary set forth herein or in any other agreement to which the parties hereto are parties or by which they are bound, the obligations of confidentiality contained herein and therein, as they relate to the transactions contemplated hereby (the “Transaction”), shall not apply to the tax structure or tax treatment of the Transaction, and each party hereto (and any employee, representative or agent of any party hereto) may disclose to any and all persons without limitation of any kind, the tax structure and tax treatment of the Transaction and all materials of any kind (including opinions or other tax analyses) that are provided to such party relating to such tax treatment and tax structure.

9.12. Nonreliance. Each Lender hereby represents that it is not relying on or looking to any margin stock (as defined in Regulation U of the Board of Governors of the Federal Reserve System) for the repayment of the Credit Extensions provided for herein.

9.13. Disclosure. The Borrower and each Lender hereby acknowledge and agree that Bank One and/or its Affiliates from time to time may hold investments in, make other loans to or have other relationships with the Borrower and its Affiliates.

9.14. Renewal and Continuation of Existing Indebtedness. Upon the effectiveness of this Agreement, all of the Existing Indebtedness outstanding on such date shall hereby be restructured, rearranged, renewed, extended and continued as provided in this Agreement and all Loans outstanding under the Prior Credit Agreement shall become Loans outstanding hereunder.

In connection herewith, the Prior Lenders have sold, assigned, transferred and conveyed, and Lenders party to this Agreement have purchased and accepted, and hereby purchase and accept, so much of the Existing Indebtedness such that each Lender’s percentage of the loans and obligations outstanding pursuant to the Prior Credit Agreement, as restructured, rearranged, renewed, extended and continued pursuant to this Agreement, shall be equal to such Lender’s Pro Rata Share upon the effectiveness of this Agreement. The Lenders acknowledge and agree that the assignment, transfer and conveyance of the Existing Indebtedness is without recourse to the Prior Lenders and without any warranties whatsoever by any Prior Lender, except as expressly set forth in the Assignment of Secured Indebtedness or the Mortgage Assignment and Amendment.

9.15. Collateral Matters; Lender Party Rate Management Agreements. The benefit of the Collateral Documents and of the provisions of this Agreement relating to the Collateral shall also extend to and be available on a pro rata basis (as set forth in Section 8.4 of this Agreement) to each Lender or Affiliate of a Lender that is a counterparty to a Lender Party Rate Management Agreement in respect of any obligations of the Borrower or any of its Restricted Subsidiaries arising under such Lender Party Rate Management Transaction, but only so long as such Lender or its Affiliate remains a party to this Agreement and this Agreement remains in effect. No Lender or Affiliate of a Lender shall have any voting or consent right under this Agreement or any Collateral Document as a result of the existence of obligations owed to it under a Lender Party Rate Management Transaction.

10.1. Appointment; Nature of Relationship. Bank One, NA is hereby appointed by each of the Lenders and the LC Issuer as its contractual representative (herein referred to as the “Administrative Agent”) hereunder and under each other Loan Document, and each of the Lenders and the LC Issuer irrevocably authorizes the Administrative Agent to act as the contractual representative of such Lender and the LC Issuer with the rights and duties expressly set forth herein and in the other Loan Documents. The Administrative Agent agrees to act as such contractual representative upon the express conditions contained in this Article X. Notwithstanding the use of the defined term “Administrative Agent,” it is expressly understood and agreed that the Administrative Agent shall not have any fiduciary responsibilities to any Lender or the LC Issuer by reason of this Agreement or any other Loan Document and that the Administrative Agent is merely acting as the contractual representative of the Lenders and the LC Issuer with only those duties as are expressly set forth in this Agreement and the other Loan Documents. In its capacity as the Lenders’ and LC Issuer’s contractual representative, the Administrative Agent (i) does not hereby assume any fiduciary duties to any of the Lenders or the LC Issuer, (ii) is a “representative” of the Lenders and the LC Issuer within the meaning of the term “secured party” as defined in the Illinois Uniform Commercial Code and (iii) is acting as an independent contractor, the rights and duties of which are limited to those expressly set forth in this Agreement and the other Loan Documents. Each of the Lenders and the LC Issuer hereby agrees to assert no claim against the Administrative Agent on any agency theory or any other theory of liability for breach of fiduciary duty, all of which claims each Lender and the LC Issuer hereby waives.

The Administrative Agent shall have and may exercise such powers under the Loan Documents as are specifically delegated to the Administrative Agent by the terms of each thereof, together with such powers as are reasonably incidental thereto.

10.3. General Immunity. Neither the Administrative Agent nor any of its directors, officers, agents or employees shall be liable to the Borrower, the Lenders or any Lender or the LC Issuer for any action taken or omitted to be taken by it or them hereunder or under any other Loan Document or in connection herewith or therewith except to the extent such action or inaction is determined in a final non-appealable judgment by a court of competent jurisdiction to have arisen from the gross negligence or willful misconduct of such Person.

10.4. No Responsibility for Loans, Recitals, Etc. Neither the Administrative Agent nor any of its directors, officers, agents or employees shall be responsible for or have any duty to ascertain, inquire into, or verify (i) any statement, warranty or representation made in connection with any Loan Document or any borrowing hereunder; (ii) the performance or observance of any of the covenants or agreements of any obligor under any Loan Document, including, without limitation, any agreement by an obligor to furnish information directly to each Lender or the LC Issuer; (iii) the satisfaction of any condition specified in Article IV, except receipt of items required to be delivered solely to the Administrative Agent; (iv) the existence or possible existence of any Default or Unmatured Default; (v) the validity, enforceability, effectiveness, sufficiency or genuineness of any Loan Document or any other instrument or writing furnished in connection therewith; (vi) the value, sufficiency, creation, perfection or priority of any Lien in any collateral security; or (vii) the financial condition of the Borrower or any guarantor of any of the Obligations or of any of the Borrower’s or any such guarantor’s respective Subsidiaries. The Administrative Agent shall have no duty to disclose to the Lenders or the LC Issuer information that is not required to be furnished by the Borrower to the Administrative Agent at such time, but is voluntarily furnished by the Borrower to the Administrative Agent (either in its capacity as Administrative Agent or in its individual capacity).

10.5. Action on Instructions of Lenders. The Administrative Agent shall in all cases be fully protected in acting, or in refraining from acting, hereunder and under any other Loan Document in accordance with written instructions signed by the Required Lenders, and such instructions and any action taken or failure to act pursuant thereto shall be binding on all of the Lenders and the LC Issuer. The Lenders and the LC Issuer hereby acknowledge that the Administrative Agent shall be under no duty to take any discretionary action permitted to be taken by it pursuant to the provisions of this Agreement or any other Loan Document unless it shall be requested in writing to do so by the Required Lenders. The Administrative Agent shall be fully justified in failing or refusing to take any action hereunder and under any other Loan Document unless it shall first be indemnified to its satisfaction by the Lenders pro rata against any and all liability, cost and expense that it may incur by reason of taking or continuing to take any such action.

10.6. Employment of Agents and Counsel. The Administrative Agent may execute any of its duties as Administrative Agent hereunder and under any other Loan Document by or through employees, agents, and attorneys-in-fact and shall not be answerable to the Lenders or the LC Issuer, except as to money or securities received by it or its authorized agents, for the default or misconduct of any such agents or attorneys-in-fact selected by it with reasonable care. The Administrative Agent shall be entitled to advice of counsel concerning the contractual arrangement between the Administrative Agent and the Lenders and the LC Issuer and all matters pertaining to the Administrative Agent’s duties hereunder and under any other Loan Document.

10.7. Reliance on Documents; Counsel. The Administrative Agent shall be entitled to rely upon any Note, notice, consent, certificate, affidavit, letter, telegram, statement, paper or document believed by it to be genuine and correct and to have been signed or sent by the proper person or persons, and, in respect to legal matters, upon the opinion of counsel selected by the Administrative Agent, which counsel may be employees of the Administrative Agent.

10.8. Administrative Agent’s Reimbursement and Indemnification. The Lenders agree to reimburse and indemnify the Administrative Agent and the LC issuer ratably in proportion to their respective Commitments (or, if the Commitments have been terminated, in proportion to their Commitments immediately prior to such termination) (i) for any amounts not reimbursed by the Borrower for which the Administrative Agent or the LC Issuer is entitled to reimbursement by the Borrower under the Loan Documents, (ii) for any other expenses incurred by the Administrative Agent on behalf of the Lenders, in connection with the preparation, execution, delivery, administration and enforcement of the Loan Documents (including, without limitation, for any expenses incurred by the Administrative Agent in connection with any dispute between the Administrative Agent and any Lender or between two or more of the Lenders) and (iii) for any 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 Administrative Agent or the LC Issuer in any way relating to or arising out of the Loan Documents or any other document delivered in connection therewith or the transactions contemplated thereby (including, without limitation, for any such amounts incurred by or asserted against the Administrative Agent or the LC Issuer in connection with any dispute between the Administrative Agent or the LC Issuer and any Lender or between two or more of the Lenders), or the enforcement of any of the terms of the Loan Documents or of any such other documents, provided that (i) no Lender shall be liable for any of the foregoing to the extent any of the foregoing is found in a final non-appealable judgment by a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of the Administrative Agent or the LC Issuer, as applicable, and (ii) any indemnification required pursuant to Section 3.5(vii) shall, notwithstanding the provisions of this Section 10.8, be paid by the relevant Lender in accordance with the provisions thereof. The obligations of the Lenders under this Section 10.8 shall survive payment of the Obligations and termination of this Agreement.

10.9. Notice of Default. The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Unmatured Default hereunder unless the Administrative Agent has received written notice from a Lender or the Borrower referring to this Agreement describing such Default or Unmatured Default and stating that such notice is a “notice of default”. In the event that the Administrative Agent receives such a notice, the Administrative Agent shall give prompt notice thereof to the Lenders.

10.10. Rights as a Lender. In the event the Administrative Agent is a Lender, the Administrative Agent shall have the same rights and powers hereunder and under any other Loan Document with respect to its Commitment and its Loans as any Lender and may exercise the same as though it were not the Administrative Agent, and the term “Lender” or “Lenders” shall, at any time when the Administrative Agent is a Lender, unless the context otherwise indicates, include the Administrative Agent in its individual capacity. The Administrative Agent and its Affiliates may accept deposits from, lend money to, and generally engage in any kind of trust, debt, equity or other transaction, in addition to those contemplated by this Agreement or any

other Loan Document, with the Borrower or any of its Subsidiaries in which the Borrower or such Subsidiary is not restricted hereby from engaging with any other Person. The Administrative Agent, in its individual capacity, is not obligated to remain a Lender.

10.11. Lender Credit Decision. Each Lender acknowledges that it has, independently and without reliance upon any Agent, the Co-Lead Arrangers, the LC Issuer or any other Lender and based on the financial statements prepared by the Borrower and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement and the other Loan Documents. Each Lender also acknowledges that it will, independently and without reliance upon any Agent, the Co-Lead Arrangers, the LC Issuer or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement and the other Loan Documents.

10.12. Successor Administrative Agent. The Administrative Agent may resign at any time by giving written notice thereof to the Lenders and the Borrower, such resignation to be effective upon the appointment of a successor Administrative Agent or, if no successor Administrative Agent has been appointed, forty-five days after the retiring Administrative Agent gives notice of its intention to resign. The Administrative Agent may be removed at any time with or without cause by written notice received by the Administrative Agent from the Required Lenders, such removal to be effective on the date specified by the Required Lenders. Upon any such resignation or removal, the Required Lenders shall have the right to appoint, on behalf of the Borrower and the Lenders, a successor Administrative Agent. If no successor Administrative Agent shall have been so appointed by the Required Lenders within thirty days after the resigning Administrative Agent’s giving notice of its intention to resign, then the resigning Administrative Agent may appoint, on behalf of the Borrower, the LC Issuer and the Lenders, a successor Administrative Agent. Notwithstanding the previous sentence, the Administrative Agent may at any time without the consent of the Borrower, the LC Issuer or any Lender, appoint any of its Affiliates which is a commercial bank as a successor Administrative Agent hereunder. If the Administrative Agent has resigned or been removed and no successor Administrative Agent has been appointed, the Lenders may perform all the duties of the Administrative Agent hereunder and the Borrower shall make all payments in respect of the Obligations to the applicable Lender and for all other purposes shall deal directly with the Lenders. No successor Administrative Agent shall be deemed to be appointed hereunder until such successor Administrative Agent has accepted the appointment. Any such successor Administrative Agent shall be a commercial bank having capital and retained earnings of at least $100,000,000. Upon the acceptance of any appointment as Administrative Agent hereunder by a successor Administrative Agent, such successor Administrative Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the resigning or removed Administrative Agent. Upon the effectiveness of the resignation or removal of the Administrative Agent, the resigning or removed Administrative Agent shall be discharged from its duties and obligations hereunder and under the Loan Documents. After the effectiveness of the resignation or removal of an Administrative Agent, the provisions of this Article X shall continue in effect for the benefit of such Administrative Agent in respect of any actions taken or omitted to be taken by it while it was acting as the Administrative Agent hereunder and under the other Loan Documents. In the event that there is a successor to the Administrative Agent by merger, or the Administrative Agent assigns its duties and obligations to an Affiliate pursuant to this Section 10.12, then the term “Prime Rate” as used in this Agreement shall mean the prime rate, base rate or other analogous rate of the new Administrative Agent.

10.13. Fees. The Borrower agrees to pay to the Administrative Agent, for its own account, the fees agreed to by the Borrower and the Administrative Agent pursuant to the Fee Letter, or as otherwise agreed from time to time.

10.14. Delegation to Affiliates. The Borrower and the Lenders agree that the Administrative Agent may delegate any of its duties under this Agreement to any of its Affiliates. Any such Affiliate (and such Affiliate’s directors, officers, agents and employees) which performs duties in connection with this Agreement shall be entitled to the same benefits of the indemnification, waiver and other protective provisions to which the Administrative Agent is entitled under Articles IX and X.

10.15. Execution of Collateral Documents. The Lenders hereby empower and authorize the Administrative Agent to execute and deliver to the Borrower on their behalf the Collateral Documents 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 Collateral Documents.

10.16. Collateral Releases. The Lenders hereby empower and authorize the Administrative Agent to execute and deliver to the Borrower on their behalf any agreements, documents or instruments as shall be necessary or appropriate to effect any releases of Collateral which shall be permitted by the terms hereof or of any other Loan Document or which shall otherwise have been approved by the Required Lenders (or, if required by the terms of Section 8.2, all of the Lenders) in writing. Notwithstanding anything herein to the contrary, the Lenders hereby authorize the Administrative Agent to release from the Lien of the Mortgage upon with the effectiveness of this Agreement any and all of the Oil and Gas Properties described on Schedule 6.2.11 - West Texas Asset Disposition.

10.17. Co-Agents, Documentation Agent, Syndication Agent, etc. Neither any of the Lenders identified in this Agreement as a “co-agent” nor the Documentation Agent or the Syndication Agent shall have any right, power, obligation, liability, responsibility or duty under this Agreement other than those applicable to all Lenders as such. Without limiting the foregoing, none of such Lenders shall have or be deemed to have a fiduciary relationship with any Lender. Each Lender hereby makes the same acknowledgments with respect to such Lenders as it makes with respect to the Administrative Agent in Section 10.11.

ARTICLE XI

SETOFF; RATABLE PAYMENTS

11.1. Setoff. In addition to, and without limitation of, any rights of the Lenders under applicable law, if the Borrower 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 the Borrower may be offset and applied toward the payment of the Obligations owing to such Lender, whether or not the Obligations, or any part thereof, shall then be due.

11.2. Ratable Payments. If any Lender, whether by setoff or otherwise, has payment made to it upon its Outstanding Credit Exposure (other than payments received pursuant to Section 3.1, 3.2, 3.4 or 3.5) in a greater proportion than that received by any other Lender, such Lender agrees, promptly upon demand, to purchase a portion of the Aggregate Outstanding Credit Exposure held by the other Lenders so that after such purchase each Lender will hold its Pro Rata Share of the Aggregate Outstanding Credit Exposure. 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 respective Pro Rata Shares of the Aggregate Outstanding Credit Exposure. In case any such payment is disturbed by legal process, or otherwise, appropriate further adjustments shall be made.

ARTICLE XII

BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS

12.1. Successors and Assigns. The terms and provisions of the Loan Documents shall be binding upon and inure to the benefit of the Borrower and the LC Issuer and the Lenders and their respective successors and assigns permitted hereby, except that (i) the Borrower shall not have the right to assign its rights or obligations under the Loan Documents without the prior written consent of each Lender and the LC Issuer, (ii) any assignment by any Lender must be made in compliance with Section 12.3, and (iii) any transfer by Participation must be made in compliance with Section 12.2. Any attempted assignment or transfer by any party not made in compliance with this Section 12.1 shall be null and void, unless such attempted assignment or transfer is treated as a participation in accordance with Section 12.3.2. The parties to this Agreement acknowledge that clause (ii) of this Section 12.1 relates only to absolute assignments and this Section 12.1 does not prohibit assignments creating security interests, including, without limitation, (x) any pledge or assignment by any Lender of all or any portion of its rights under this Agreement and any Note to a Federal Reserve Bank or (y) in the case of a Lender which is a Fund, any pledge or assignment of all or any portion of its rights under this Agreement and any Note to its trustee in support of its obligations to its trustee; provided, however, that no such pledge or assignment creating a security interest shall release the transferor Lender from its obligations hereunder unless and until the parties thereto have complied with the provisions of Section 12.3. The Administrative Agent may treat the Person which made any Loan or which holds any Note as the owner thereof for all purposes hereof unless and until such Person complies with Section 12.3; provided, however, that the Administrative Agent may in its discretion (but shall not be required to) follow instructions from the Person which made any Loan or which holds any Note to direct payments relating to such Loan or Note to another Person. Any assignee of the rights to any Loan or any Note agrees by acceptance of such assignment to be bound by all the terms and provisions of the Loan Documents. Any request, authority or consent of any Person, who at the time of making such request or giving such authority or consent is the owner of the rights to any Loan (whether or not a Note has been issued in evidence thereof), shall be conclusive and binding on any subsequent holder or assignee of the rights to such Loan.

12.2. Participations.

12.2.1. Permitted Participants; Effect. Any Lender may at any time sell to one or more banks or other entities (“Participants”) participating interests in any Outstanding Credit Exposure of such Lender, any Note held by such Lender, any Commitment of such Lender or any other interest of such Lender under the Loan Documents. In the event of any such sale by a Lender of participating interests to a Participant, such Lender’s obligations under the Loan Documents shall remain unchanged, such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, such Lender shall remain the owner of its Outstanding Credit Exposure and the holder of any Note issued to it in evidence thereof for all purposes under the Loan Documents, all amounts payable by the Borrower under this Agreement shall be determined as if such Lender had not sold such participating interests, and the Borrower and the Administrative Agent shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under the Loan Documents.

12.2.2. Voting Rights. Each Lender shall retain the sole right to approve, without the consent of any Participant, any amendment, modification or waiver of any provision of the Loan Documents other than any amendment, modification or waiver with respect to any Credit Extension or Commitment in which such Participant has an interest which would require consent of all of the Lenders pursuant to the terms of Section 8.2 or of any other Loan Document. Participates shall have no voting rights except with respect to any amendment, modification or waiver of any provision with respect to any Credit Extension or Commitment in which such Participant has an interest which would require consent of all of the Lenders pursuant to the terms of Section 8.2 or of any other Loan Document.

12.2.3. Benefit of Certain Provisions. The Borrower agrees that each Participant shall be deemed to have the right of setoff provided in Section 11.1 in respect of its participating interest in amounts owing under the Loan Documents to the same extent as if the amount of its participating interest were owing directly to it as a Lender under the Loan Documents, provided that each Lender shall retain the right of setoff provided in Section 11.1 with respect to the amount of participating interests sold to each Participant. The Lenders agree to share with each Participant, and each Participant, by exercising the right of setoff provided in Section 11.1, agrees to share with each Lender, any amount received pursuant to the exercise of its right of setoff, such amounts to be shared in accordance with Section 11.2 as if each Participant were a Lender. The Borrower further agrees that each Participant shall be entitled to the benefits of Sections 3.1, 3.2, 3.4 and 3.5 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to Section 12.3, provided that (i) a Participant shall not be entitled to receive any greater payment under Section 3.1, 3.2 or 3.5 than the Lender who sold the participating interest to such Participant would have received had it retained such interest for its own account, unless the sale of such interest to such Participant is made with the prior written consent of the Borrower, and (ii) any Participant not incorporated under the laws of the United States of America or any State thereof agrees to comply with the provisions of Section 3.5 to the same extent as if it were a Lender.

12.3. Assignments.

12.3.1. Permitted Assignments. Any Lender may at any time assign to one or more banks or other entities (“Purchasers”) all or any part of its rights and obligations under the Loan Documents. Such assignment shall be substantially in the form of Exhibit B or in such other form as may be agreed to by the parties thereto. Each such assignment with respect to a Purchaser which is not a Lender or an Affiliate of a Lender or an Approved Fund shall either be in an amount equal to the entire applicable Commitment and Loans of the assigning Lender or (unless each of the Borrower, the LC Issuer and the Administrative Agent otherwise consents) be in an aggregate amount not less than $5,000,000. The amount of the assignment shall be based on the Commitment or outstanding Loans (if the Commitment has been terminated) subject to the assignment, determined as of the date of such assignment or as of the “Trade Date,” if the “Trade Date” is specified in the assignment.

12.3.2. Consents. The consent of the Borrower shall be required prior to an assignment becoming effective unless the Purchaser is a Lender, an Affiliate of a Lender or an Approved Fund, provided that the consent of the Borrower shall not be required if a Default has occurred and is continuing. The consent of the Administrative Agent and the LC Issuer shall be required prior to an assignment becoming effective unless the Purchaser is a Lender, an Affiliate of a Lender or an Approved Fund. Any consent required under this Section 12.3.2 shall not be unreasonably withheld or delayed.

12.3.3. Effect; Effective Date. Upon (i) delivery to the Administrative Agent of an assignment, together with any consents required by Sections 12.3.1 and 12.3.2, and (ii) payment of a $3,500 fee to the Administrative Agent for processing such assignment (unless such fee is waived by the Administrative Agent), such assignment shall become effective on the effective date specified in such assignment. The assignment shall contain a representation by the Purchaser to the effect that none of the consideration used to make the purchase of the Commitment and Outstanding Credit Exposure under the applicable assignment agreement constitutes “plan assets” as defined under ERISA and that the rights and interests of the Purchaser in and under the Loan Documents will not be “plan assets” under ERISA. On and after the effective date of such assignment, such Purchaser shall for all purposes be a Lender party to this Agreement and any other Loan Document executed by or on behalf of the Lenders and shall have all the rights and obligations of a Lender under the Loan Documents, to the same extent as if it were an original party thereto, and the transferor Lender shall be released with respect to the Commitment and Outstanding Credit Exposure assigned to such Purchaser without any further consent or action by the Borrower, the Lenders or the Administrative Agent. In the case of an assignment covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a Lender hereunder but shall continue to be entitled to the benefits of, and subject to, those provisions of this Agreement and the other Loan Documents which survive payment of the Obligations and termination of the applicable agreement. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 12.3 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with Section 12.2. Upon the consummation of any assignment to a Purchaser pursuant to this Section 12.3.3, the transferor Lender, the Administrative Agent and the Borrower shall, if the transferor Lender or the Purchaser desires that its Loans be evidenced by Notes, make appropriate arrangements so

that new Notes or, as appropriate, replacement Notes are issued to such transferor Lender and new Notes or, as appropriate, replacement Notes, are issued to such Purchaser, in each case in principal amounts reflecting their respective Commitments, as adjusted pursuant to such assignment.

12.3.4. Register. The Administrative Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at one of its offices in Chicago, Illinois a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

12.4. Dissemination of Information. The Borrower authorizes each Lender to disclose to any Participant or Purchaser or any other Person acquiring an interest in the Loan Documents by operation of law (each a “Transferee”) and any prospective Transferee any and all information in such Lender’s possession concerning the creditworthiness of the Borrower and its Subsidiaries, including without limitation any information contained in any Reports; provided that each Transferee and prospective Transferee agrees to be bound by Section 9.11 of this Agreement.

12.5. Tax Treatment. If any interest in any Loan Document is transferred to any Transferee that is not incorporated under the laws of the United States or any State thereof, the transferor Lender shall cause such Transferee, concurrently with the effectiveness of such transfer, to comply with the provisions of Section 3.5(iv).
