Not later than noon (Houston time) on each Borrowing Date, each Lender shall make available its Loan or Loans in funds immediately available in Houston to the Agent at its address specified pursuant to Article XIII. The Agent will make the funds so received from the Lenders available to the Borrower at the Agent’s aforesaid address.

2.10. 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 2.10 or are repaid in accordance with Section 2.8. 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 2.8 or (y) the Borrower shall have given the 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 2.7, 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 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. (Houston 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.

2.11. 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 2.10, to but excluding the date it is paid or is converted into a Eurodollar Advance pursuant to Section 2.10 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 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.

2.12. Rates Applicable After Default. Notwithstanding anything to the contrary contained in Sections 2.9 or 2.10, 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 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 2% per annum and (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 2% per annum, provided that, during the continuance of a Default under Sections 7.6 or 7.7, the interest rates set forth in clauses (i) and (ii) above shall be applicable to all Credit Extensions without any election or action on the part of the Agent or any Lender.

2.13. Method of Payment. All payments of the Obligations hereunder shall be made, without setoff, deduction, or counterclaim, in immediately available funds to the Agent at the Agent’s address specified pursuant to Article XIII, or at any other Lending Installation of the Agent specified in writing by the 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 Lenders, or as otherwise specifically required hereunder) be applied ratably by the Agent among the Lenders. Each payment delivered to the Agent for the account of any Lender shall be delivered promptly by the Agent to such Lender in the same type of funds that the Agent received at its address specified pursuant to Article XIII or at any Lending

Installation specified in a notice received by the Agent from such Lender. Each reference to the Agent in this Section 2.13 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 2.21.6. The Agent is hereby authorized to charge the account of the Borrower maintained with JPMorgan Chase for each payment of principal, interest and fees as it becomes due hereunder.

2.14. 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 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 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 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 Agent. Thereafter, the Loans evidenced by such Note and interest thereon shall at all times (including after any assignment pursuant to Section 12.3) be represented by one or more Notes payable to the order of the payee named therein or any assignee pursuant to Section 12.3, except to the extent that any such Lender or assignee subsequently returns any such Note for cancellation and requests that such Loans once again be evidenced as described in paragraphs (i) and (ii) above.

2.15. Telephonic Notices. The Borrower hereby authorizes the Lenders and the 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 designated in writing by the Borrower from time to time, 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 Agent a written confirmation, if such confirmation is requested by the 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 Agent and the Lenders, the records of the Agent and the Lenders shall govern absent manifest error.

2.16. 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 on Floating Rate Advances, commitment fees and LC Fees shall be calculated for actual days elapsed on a basis of a 365, or when appropriate 366, day per year. 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 on Eurodollar Advances shall be calculated for actual days elapsed on the basis of a 360-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 a Floating Rate 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.

2.17. Notification of Advances, Interest Rates, Facility LCs, Prepayments and Commitment Reductions. Promptly after receipt thereof, the 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 Agent will notify each Lender of the contents of each request for issuance of a Facility LC hereunder. The 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.

2.18. 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 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.

2.19. Non-Receipt of Funds by the Agent. Unless the Borrower or a Lender, as the case may be, notifies the Agent prior to the date on which it is scheduled to make payment to the 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 Agent for the account of the Lenders, that it does not intend to make such payment, the Agent may assume that such payment has been made. The 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 Agent, the recipient of such payment shall, on demand by the Agent, repay to the Agent the amount so made available together with interest thereon in respect of each day during the period commencing on the date such amount was so made available by the Agent until the date the 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.

2.20. Replacement of Lender. If the Borrower is required pursuant to Sections 3.1, 3.2 or 3.5 to make any additional payment to any Lender or if any Lender’s obligation to make or continue, or to convert Floating Rate Advances into, Eurodollar Advances shall be suspended pursuant to Section 3.3 (any Lender so affected an “Affected Lender”), the Borrower may elect, if such amounts continue to be charged or such suspension is still effective, to replace such Affected Lender as a Lender party to this Agreement, provided that no Default or Unmatured Default shall have occurred and be continuing at the time of such replacement, and provided further that, concurrently with such replacement, (i) another bank or other entity which is reasonably satisfactory to the Borrower and the Agent shall agree, as of such date, to purchase for cash the Advances and other Obligations due to the Affected Lender pursuant to an assignment substantially in the form of Exhibit C and to become a Lender for all purposes under this Agreement and to assume all obligations of the Affected Lender to be terminated as of such date and to comply with the requirements of Section 12.3 applicable to assignments, and (ii) the Borrower shall pay to such Affected Lender in same day funds on the day of such replacement (A) all interest, fees and other amounts then accrued but unpaid to such Affected Lender by the Borrower hereunder to and including the date of termination, including without limitation payments due to such Affected Lender under Sections 3.1, 3.2 and 3.5, and (B) an amount, if any, equal to the payment which would have been due to such Lender on the day of such replacement under Section 3.4 had the Loans of such Affected Lender been prepaid on such date rather than sold to the replacement Lender.

2.21. Facility LCs.

2.21.1. Issuance. Except as provided below, 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 $15,000,000 and (ii) the Aggregate Outstanding Credit Exposure shall not exceed the lesser of (a) the Aggregate Commitment and (b) the Borrowing Base. 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 tenor 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 LC Issuer provides prior notice of non-renewal to the beneficiary of such Facility LC.

2.21.2. Participations. Upon the issuance or Modification by the LC Issuer of a Facility LC in accordance with this Section 2.21, 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.

2.21.3. Notice. Subject to Section 2.21.1, the Borrower shall give the LC Issuer notice prior to 10:00 a.m. (Houston 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 Agent, and the 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.

2.21.4. LC Fees. The Borrower shall pay to the Agent, for the account of the Lenders ratably in accordance with their respective Pro Rata Shares, with respect to each Facility LC, a letter of credit fee at a per annum rate equal to the Applicable Margin for Eurodollar Rate Loans per annum on the average daily undrawn stated amount under such standby Facility LC, such fee to be payable in arrears on each Payment Date (such fee described in this sentence an “LC Fee”); provided, that during the continuance of a Default the LC Fee shall be the sum of 2% plus the Applicable Margin for Eurodollar Rate Loans per annum. The Borrower shall also pay to the LC Issuer for its own account (x) in arrears on each Payment

Date, a fronting fee of .25% per annum of the face amount of each Facility LC, and (y) documentary and processing charges in connection with the issuance or Modification 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.

2.21.5. 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 Agent and the 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 pursuant to Section 2.21.6 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. (Houston 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.

2.21.6. 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 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 2.21.5. Subject to the terms and conditions of this Agreement (including without limitation the submission of a Borrowing Notice in compliance with Section 2.9 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.

2.21.7. Obligations Absolute. The Borrower’s obligations under this Section 2.21 shall be absolute and unconditional under any and all circumstances and irrespective of any setoff, counterclaim or defense to payment that 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 2.21.7 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 2.21.6.

2.21.8. 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 2.21, 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.

2.21.9. Indemnification. The Borrower hereby agrees to indemnify and hold harmless each Lender, the LC Issuer and the 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 the Agent may incur (or which may be claimed against such Lender, the LC Issuer or the 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 the 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 2.21.9 is intended to limit the obligations of the Borrower under any other provision of this Agreement.

2.21.10. 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 2.21 or any action taken or omitted by such indemnitees hereunder.

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

2.22. Collateral

2.22.1 First Lien. The full and complete payment and performance of the Obligations shall be secured under the Collateral Documents by (i) first and prior Lender Liens in, to and on at least ninety percent (90%) of the PDP Present Value of Oil and Gas Properties located in the United States or its offshore waters and at least eighty percent (80%) of the aggregate Proved Reserves of Oil and Gas Properties located in the United States or its offshore waters, in each case, now owned or hereafter acquired by the Borrower or any of its Subsidiaries and (ii) the Pledge Agreements.

2.22.2 Lender Liens. The Lender Liens in the Collateral shall be further evidenced and governed by the Collateral Documents.

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 or 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 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 LCs or participations 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 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 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 or Commitment or Facility LCs or participations therein, then, within 15 days of demand by such Lender or the LC Issuer, the Borrower shall pay such Lender or the LC Issuer such additional amount or amounts as will compensate such Lender or the LC Issuer 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 30 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, 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 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.

3.5.1 All payments by the Borrower to or for the account of any Lender, the LC Issuer or the 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 Agent, (i) 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 Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions, (iii) the Borrower shall pay the full amount deducted to the relevant authority in accordance with applicable Law and (iv) the Borrower shall furnish to the Agent the original copy of a receipt evidencing payment thereof within 30 days after such payment is made.

3.5.2 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”).

3.5.3 The Borrower hereby agrees to indemnify the 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 Agent, the LC Issuer or such Lender 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 Agent, the LC Issuer or such Lender makes demand therefor pursuant to Section 3.6.

3.5.4 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 less than ten Business Days after the date of this Agreement, (i) deliver to each of the Borrower and the 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 (ii) deliver to each of the Borrower and the 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 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 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 Agent that it is not capable of receiving payments without any deduction or withholding of United States federal income tax.

3.5.5 For any period during which a Non-U.S. Lender has failed to provide the Borrower with an appropriate form pursuant to Section 3.5.4 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; provided that, should a Non-U.S. Lender which is otherwise exempt from or subject to a reduced rate of withholding tax become subject to Taxes because of its failure to deliver a form required under Section 3.5.4, the Borrower shall take such steps as such Non-U.S. Lender shall reasonably request to assist such Non-U.S. Lender to recover such Taxes.

3.5.6 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 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.

3.5.7 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 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 Agent of a change in circumstances which rendered its exemption from withholding ineffective, or for any other reason), such Lender shall indemnify the Agent fully for all amounts paid, directly or indirectly, by the Agent as tax, withholding therefor, or otherwise, including penalties and interest, and including taxes imposed by any jurisdiction on amounts payable to the Agent, under this Section 3.5.7, together with all costs and expenses related thereto (including attorneys’ fees and time charges of attorneys for the Agent, which attorneys may be employees of the Agent). The obligations of the Lenders under this Section 3.5.7 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 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 Sections 3.1, 3.2, 3.4 and 3.5 shall survive payment of the Obligations and termination of this Agreement.

The Parent is a corporation duly organized validly existing and in good standing under the Laws of Delaware. Each of the Parent, the Borrower and their Subsidiaries is a corporation, partnership or limited liability company duly and properly incorporated or organized, as the case may be, validly existing and (to the extent such concept applies to such entity) in good standing under the Laws of its jurisdiction of incorporation or organization. Each of the Parent, the Borrower and their Subsidiaries has all requisite authority to conduct its business in each jurisdiction in which its business is conducted. Except as set forth in Schedule 5.1, neither the Parent, the Borrower nor any of their Subsidiaries has used or transacted business under any other name in the five (5) year period preceding the date hereof. The Borrower is a Wholly-Owned Subsidiary of the Parent.

5.2. Authorization and Validity. The Parent, the Borrower and their Subsidiaries have the power and authority and legal right to execute and deliver the Loan Documents to which they respectively are a party and to perform their respective obligations thereunder. The execution and delivery by the Parent, the Borrower and their Subsidiaries of the Loan Documents to which they respectively are a party and the performance of their respective obligations thereunder have been duly authorized by proper corporate, partnership or limited liability company proceedings, and the Loan Documents to which they respectively are a party constitute their legal, valid and binding obligations enforceable against them in accordance with their terms, except as enforceability may be limited by bankruptcy, insolvency or similar Laws affecting the enforcement of creditors’ rights generally.

5.3. No Conflict; Government Consent. Neither the execution and delivery by the Parent, the Borrower or any of their Subsidiaries of the Loan Documents to which they respectively are a party, nor the consummation of the transactions therein contemplated, nor compliance with the provisions thereof will violate (i) any Law, rule, regulation, order, writ, judgment, injunction, decree or award binding on them or (ii) the Parent’s, the Borrower’s or any Subsidiary’s articles or certificate of incorporation, partnership agreement, certificate of partnership, articles or certificate of organization, by-laws, or operating or other management agreement, as the case may be, or (iii) the provisions of any indenture, instrument or agreement to which the Parent, the Borrower or any of their Subsidiaries is a party or is subject, or by which it, or its Property, is bound, or conflict with or constitute a default thereunder, or result in, or require, the creation or imposition of any Lien in, of or on the Property of the Parent, the Borrower or a Subsidiary pursuant to the terms of any such indenture, instrument or agreement.

No order, consent, adjudication, approval, license, authorization, or validation of, or filing, recording or registration with, or exemption by, or other action in respect of any governmental or public body or authority, or any subdivision thereof, which has not been obtained by the Parent, the Borrower or any of their Subsidiaries, is required to be obtained by the Parent, the Borrower or any of their Subsidiaries in connection with the execution and delivery of the Loan Documents, the borrowings under this Agreement, the payment and performance by the Borrower of the Obligations or the legality, validity, binding effect or enforceability of any of the Loan Documents.

5.4. Financial Statements. The September 30, 2005 consolidated financial statements of the Parent, and its consolidated subsidiaries heretofore delivered to the Agent were prepared in accordance with Agreement Accounting Principles in effect on the date such statements were prepared and fairly present the consolidated financial condition and operations of the Parent and its consolidated subsidiaries at such date and the consolidated results of their operations for the period then ended.

5.5. Material Adverse Effect. Since the date of the financial statements delivered pursuant to Section 5.4, there has been no change in the business, Property, prospects, condition (financial or otherwise) or results of operations of the Parent, the Borrower and their Subsidiaries which could reasonably be expected to have a Material Adverse Effect.

The United States income tax returns of the Parent, the Borrower and their Subsidiaries have not been audited by the Internal Revenue Service during the time period between September, 2000 and the date of this Agreement. No tax liens have been filed and no claims are being asserted with respect to any such Taxes.

5.7. Litigation and Contingent Obligations. Except as set forth on Schedule 5.7, there is no litigation, arbitration, governmental investigation, proceeding or inquiry pending or, to the knowledge of any of their officers, threatened against or affecting the Borrower or any of its Subsidiaries which could reasonably be expected to have a Material Adverse Effect or which seeks to prevent, enjoin or delay the making of any Credit Extension. Other than any liability incident to any litigation, arbitration or proceeding which (i) could not reasonably be expected to have a Material Adverse Effect or (ii) is set forth on Schedule 5.7, the Borrower has no material contingent obligations not provided for or disclosed in the financial statements referred to in Section 5.4.

5.10. Accuracy of Information. Neither the Loan Documents nor any other agreement, document, certificate, statement, information, exhibit or report (other than projections and review reports) furnished to the Agent or any Lender by or on behalf of the Borrower or any Subsidiary in connection with the transactions contemplated in any of the Loan Documents contains any untrue statement of a material fact or omits to state a material fact necessary in order to make the statements contained herein or therein not misleading. All writings heretofore or hereafter exhibited or delivered to the Agent or any Lender by or on behalf of the Borrower or any Subsidiary are and will be genuine and in all respects what they purport to be.

5.11. Regulation U. Margin stock (as defined in Regulation U) constitutes less than 25% of the value of those assets of the Parent, the Borrower and their Subsidiaries which are subject to any limitation on sale, pledge, or other restriction hereunder.

5.12. Material Agreements. Neither the Parent, the Borrower nor any Subsidiary is a party to any agreement or instrument or subject to any charter or other corporate restriction which could reasonably be expected to have a Material Adverse Effect.

5.13. Compliance With Laws.

5.13.1. The Parent, the Borrower and their Subsidiaries have complied with all applicable statutes, rules, regulations, orders and restrictions of any domestic or foreign

government or any instrumentality or agency thereof having jurisdiction over the conduct of their respective businesses or the ownership of their respective Property except for any failure to comply with any of the foregoing which could not reasonably be expected to have a Material Adverse Effect.

The Parent, the Borrower and their Subsidiaries have all material licenses, permits, franchises, or other governmental authorizations necessary for the ownership and, if it is the operator, operation of their Oil and Gas Properties and the conduct of their respective businesses, and are in compliance in all material respects with the terms and conditions of all such licenses, permits, franchises, or other governmental authorizations. Their Oil and Gas Properties (and properties unitized therewith) operated by Borrower or its Subsidiaries have been maintained, operated and developed in a good and workman like manner and in conformity with all applicable Laws and all rules, regulations and orders of all duly constituted Tribunals having jurisdiction and in conformity with the provisions of all leases, subleases or other contracts comprising a part of the Hydrocarbon Interests and other contracts and agreements forming a part of the Oil and Gas Properties; specifically in this connection, (i) after the date of this Agreement, no Oil and Gas Property is subject to having allowable production reduced below the full and regular allowable (including the maximum permissible tolerance) because of any overproduction (whether or not the same was permissible at the time) prior to the date of this Agreement; and (ii) none of the wells comprising a part of the Oil and Gas Properties (or properties unitized therewith) are deviated from the vertical more than the maximum permitted by applicable Laws and regulations, rules and orders of any Tribunal having appropriate jurisdiction, and such wells are, in fact, bottomed under and are producing from, and the wellbores are wholly within, the Oil and Gas Properties (or in the case of wells located on properties unitized therewith, such unitized properties).

5.14.1. Except as set forth on Schedule 5.14, on the date of this Agreement, the Parent, the Borrower and their Subsidiaries will have good and defensible title, free of all Liens other than those permitted by Section 6.15 or contemplated otherwise in this Agreement, all of the Collateral (including but not limited to their respective material Oil and Gas Properties).

After giving full effect to the Liens permitted under Section 6.15, except as set out in Schedule 5.14, the Parent, the Borrower or their Subsidiaries own the net interests in production attributable to the wells and units evaluated in the Initial Reserve Report or the most recent Reserve Report furnished to the Lenders pursuant to Sections 6.1(x) or (xi). The ownership of the Oil and Gas Properties shall not in any material respect obligate the Borrower or any Subsidiary to bear the costs and expenses relating to the maintenance, development and operations of each such Oil and Gas Property in any amount in excess of the working interest of each Oil and Gas Property set forth in the Initial Reserve Report or the most recent Reserve Report furnished to the Lenders pursuant to Sections 6.1(x) or (xi). The Parent, the Borrower and their Subsidiaries shall have paid all royalties payable under the oil and gas leases to which

5.14.4 Upon filing of the Deeds of Trust with the Clerk of the County or Parish where the Property thereby covered is located and the financing statements with the appropriate governmental entity, and upon filing financing statements relating to the other Collateral Documents with the appropriate governmental entity, the Collateral Documents will constitute legal, valid and continuing perfected first liens on the Collateral as security for the Obligations, free and clear of all other Liens, except for the Liens permitted by Section 6.15.

5.15. Plan Assets; Prohibited Transactions. The Borrower is not an entity deemed to hold “plan assets” within the meaning of 29 C.F.R. § 2510.3-101 of an employee benefit plan (as defined in Section 3(3) of ERISA) which is subject to Title I of ERISA or any plan (within the meaning of Section 4975 of the Code), and neither the execution of this Agreement nor the making of Loans hereunder gives rise to a prohibited transaction within the meaning of Section 406 of ERISA or Section 4975 of the Code.

As used in this subsection, the term “Projected Oil Production” and “Projected Gas Production” means, in the case of each such commodity, the projected production of oil or gas, as the case may be, (measured by volume unit or BTU equivalent, not sales price) for the term of the contracts or a particular month, as applicable, from Oil and Gas Properties and interests owned by the Parent, the Borrower and their Subsidiaries which are located in or offshore of the United States of America and which have attributable to them Proved Reserves, as such production is determined by the Agent using the most recent Reserve Report delivered pursuant to Section 6.1, after deducting projected production from any properties or interests sold or under contract for sale that had been included in such report and after adding projected production from any properties or interests that had not been reflected in such report but that are reflected in a separate or supplemental reports meeting the requirements of Section 6.1 above and otherwise are satisfactory to the Agent; and

(ii)

contracts entered into by the Borrower or any Subsidiary with the purpose and effect of fixing interest rates on a principal amount of indebtedness of such Person that is accruing interest at a variable rate, provided that (a) the aggregate notional amount of such contracts never exceeds eighty-five percent (85%) of the anticipated outstanding principal balance of the Indebtedness to be hedged by such contracts or an average of such principal balances calculated using a generally accepted method of matching interest swap contracts to declining principal balances, (b) the floating rate index of each such contract generally matches the index used to determine the floating rates of interest on the corresponding indebtedness to be hedged by such contract, and (c) each such contract is with a counterparty or has a guarantor of the obligation of the counterparty who (unless such counterparty is a Lender or one of its Affiliates) at the time the contract is made has (or whose company has) long-term obligations rated AA or AA2 or better, respectively, by either S&P or Moody’s or is an investment grade-rated industry participant.

6.24. Sale of Accounts. Neither the Borrower nor any Subsidiary will sell or otherwise dispose of any notes receivable or accounts receivable, with or without recourse.

6.25. Sale and Leaseback Transactions and Other Off-Balance Sheet Liabilities. Neither the Borrower nor any Subsidiary will enter into or suffer to exist any (i) Sale and Leaseback Transaction or (ii) any other transaction pursuant to which it incurs or has incurred Off-Balance Sheet Liabilities, except for (i) Non-Recourse Indebtedness permitted to be incurred under the terms of Section 6.11; and (ii) Rate Management Transactions permitted to be incurred under the terms of Section 6.23.

6.26. Contingent Obligations. Neither the Borrower nor any Subsidiary will make or suffer to exist any Contingent Obligation (including, without limitation, any Contingent Obligation with respect to the obligations of a Subsidiary), other than those in connection with guarantees of the obligations of Subsidiaries in connection with owning and operating Oil and Gas Properties in the ordinary course of business, except (i) by endorsement of instruments for deposit or collection in the ordinary course of business, (ii) the Reimbursement Obligations, and (iii) that the Borrower or any Subsidiary may incur Contingent Obligations with respect to Obligations permitted hereunder.

6.27. Financial Contracts. Neither the Borrower nor any Subsidiary will enter into or remain liable upon any Financial Contract, except for Rate Management Transactions required or permitted under Section 6.25.

6.28. Financial Covenants.

6.28.1 Debt Coverage Ratio. The Borrower will not permit the ratio of (A) Consolidated Indebtedness to (B) annualized Consolidated EBITDDA, determined on a

rolling four quarter basis (and taking into account, on a proforma basis, the revenues and expenses attributable to any Oil and Gas Properties acquired during the rolling four quarter period and deducting any revenues and expenses attributable to Oil & Gas Properties disposed of during such period) to be greater than 2.50 to 1.00.

6.28.2 Current Ratio. The Borrower will not permit the ratio of Consolidated Current Assets to Consolidated Current Liabilities, excluding current maturities of long term debt and current payables resulting from any Rate Management Transaction, to be less than 1.0 to 1.0 at any time.

6.30. Senior Notes. The Senior Notes will be unsecured obligations of Parent and the Borrower, as co-issuers, guarantied by the unsecured guaranties of the Subsidiary Guarantors (as such term is described in the Senior Notes Indenture).

The Borrower will not, and will not permit any Guarantor or any Subsidiary to, make any (i) amendment or modification to the Senior Notes or the Senior Notes Indenture (other than supplemental indentures to add subsidiary guarantors as contemplated by the Senior Notes Indenture or, in the event of any discrepancy, to conform the Senior Notes Indenture to the terms in the Senior Notes Indenture) which would be materially adverse to the Lenders without the prior written consent of the Required Lenders; or (ii) directly or indirectly voluntarily prepay, defease or in substance defease, purchase, redeem, retire or otherwise acquire, any portion of the Senior Notes without the prior written consent of the Required Lenders; provided that (I) Parent may redeem Senior Notes out of the net cash proceeds of Equity Offerings (as that term is defined in the Senior Notes Indenture) to the extent described in the Senior Notes; and (II) the Borrower and Parent may comply with their obligations with respect to the purchase of Senior Notes upon (x) an Asset Disposition (as that term is defined in the Senior Notes Indenture) to the extent set forth in the Senior Notes Indenture so long as, prior to such purchase, the Borrower shall have offered to prepay the Obligations to the Lenders by a like amount and the Lenders shall have declined that offer or (y) a Change of Control (as that term is defined in the Senior Notes Indenture) to the extent set forth in the Senior Notes Indenture so long as, if such Change of Control constitutes an Unmatured Default or an Event of Default, the Obligations to the Lender shall have been paid in full prior to such purchase.

ARTICLE VIII

ACCELERATION, WAIVERS, AMENDMENTS AND REMEDIES

8.1. Acceleration. If any Default described in Sections 7.6, 7.7 or 7.20 occurs with respect to the Borrower or any of its Subsidiaries, 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 Agent, the LC Issuer or any Lender and the Borrower will be and become thereby unconditionally obligated, without any further notice, act or demand, to pay to the Agent an amount in immediately available funds, which funds shall be held in the Facility LC Collateral Account, equal to the excess of (x) the amount of LC Obligations at such time, over (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 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 notice of any kind, all of which the Borrower hereby expressly waives, and (b) upon notice to the Borrower and in addition to the continuing right to demand payment of all amounts payable under this Agreement, 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 Agent the Collateral Shortfall Amount, which funds shall be deposited in the Facility LC Collateral Account.

	(i)		If at any time while any Default is continuing, the Agent determines that the Collateral Shortfall Amount is greater than zero, the 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 Agent the Collateral Shortfall Amount, which funds shall be deposited in the Facility LC Collateral Account.

	(ii)		The 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 or 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.

	(iii)		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 Agent to the Borrower or paid to whomever may be legally entitled thereto at such time.

	(iv)		If, within ten (10) days after acceleration of the maturity of the Obligations or termination of the obligations 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 Sections 7.6, 7.7 or 7.20 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 Agent shall, by notice to the Borrower, rescind and annul such acceleration and/or termination.

8.2. Amendments. Subject to the provisions of this Article VIII, the Required Lenders (or the 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, without the consent of all of the Lenders:

	(i)		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 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;

	(ii)		reduce the percentage specified in the definition of Required Lenders;

	(iii)		extend the Facility Termination Date, or reduce the amount or extend the payment date for, the mandatory payments required under Section 2.2.7, or increase the Commitment of any Lender hereunder or the commitment to issue Facility LCs, or permit the Borrower to assign its rights under this Agreement;

	(iv)		amend this Section 8.2; or

	(v)		except as provided in the Collateral Documents, release all or substantially all of the Collateral.

No amendment of any provision of this Agreement relating to the Agent shall be effective without the written consent of the Agent, and no amendment of any provision relating to the LC Issuer shall be effective without the written consent of the LC Issuer. The Agent may waive payment of the fee required under Section 12.3.2 without obtaining the consent of any other party to this Agreement.

8.3. Preservation of Rights. No delay or omission of the Lenders, the LC Issuer or the Agent to exercise 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 Agent, the LC Issuer and the Lenders until the Obligations have been paid in full.

9.3. Headings. Section headings in the Loan Documents are for convenience of reference only, and shall not govern the interpretation of any of the provisions of the Loan Documents.

9.4. ENTIRE AGREEMENT. THE LOAN DOCUMENTS EMBODY THE ENTIRE AGREEMENT AND UNDERSTANDING AMONG THE BORROWER, THE AGENT, THE LC ISSUER AND THE LENDERS AND SUPERSEDE ALL PRIOR AGREEMENTS AND UNDERSTANDINGS AMONG THE BORROWER, THE AGENT, THE LC ISSUER AND THE LENDERS RELATING TO THE SUBJECT MATTER THEREOF OTHER THAN THE FEE LETTER DESCRIBED IN SECTION 10.13.

9.5. Several Obligations; Benefits of this Agreement. The respective obligations of the Lenders hereunder are several and not joint and no Lender shall be the partner or agent of any other (except to the extent to which the Agent is authorized to act as such). 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 Arranger 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 Agent and the Arranger for any costs, internal charges and out-of-pocket expenses (including attorneys’ fees and time charges of outside attorneys for the Agent, the Arranger, the LC Issuer and the Lenders) paid or incurred by the Agent or the Arranger in connection with the preparation, negotiation, execution, delivery, syndication, review, amendment, modification, and administration of the Loan Documents. The Borrower also agrees to reimburse the Agent, the Arranger, the LC Issuer and the Lenders for any costs, internal charges and out-of-pocket expenses (including attorneys’ fees and time charges of outside attorneys for the Agent, the Arranger, the LC Issuer and the Lenders) paid or incurred by the Agent, the Arranger, the LC Issuer or any Lender in connection

with the collection and enforcement of the Loan Documents. The Borrower acknowledges that from time to time JPMorgan Chase may prepare and may distribute to the Lenders (but shall have no obligation or duty to prepare or to distribute to the Lenders) certain audit reports (the “Reports”) pertaining to the Borrower’s assets for internal use by JPMorgan Chase from information furnished to it by or on behalf of the Borrower, after JPMorgan Chase has exercised its rights of inspection pursuant to this Agreement.

(ii) The Borrower hereby further agrees to indemnify the Agent, the Arranger, the LC Issuer, each Lender, their respective Affiliates, and each of their directors, officers and employees against all losses, claims, damages, penalties, judgments, liabilities and expenses (including, without limitation, all expenses of litigation or preparation therefor whether or not the Agent, the Arranger, 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. 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 Agent with sufficient counterparts so that the 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 Agreement Accounting Principles, except that any calculation or determination which is to be made on a consolidated basis shall be made for the Borrower and all its Subsidiaries, including those Subsidiaries, if any, which are unconsolidated on the Borrower’s audited financial statements.

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 Agent on the other hand shall be solely that of the Borrower and Lender. Neither the Agent, the Arranger, the LC Issuer nor any Lender shall have any fiduciary responsibilities to the Borrower. Neither the Agent, the Arranger, the LC Issuer nor any Lender undertakes any responsibility to the Borrower to review or inform the Borrower of any matter in connection with any phase of the Borrower’s business or operations. The

Borrower agrees that neither the Agent, the Arranger, the LC Issuer nor any Lender shall have liability to the Borrower (whether sounding in tort, contract or otherwise) for losses suffered by the Borrower 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. Neither the Agent, the Arranger, 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 in connection with, arising out of, or in any way related to the Loan Documents or the transactions contemplated thereby.

9.11. Confidentiality. 9.11. Each Lender agrees to hold any confidential information which it may receive from the Borrower pursuant to this Agreement 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 herein to the contrary, confidential information shall not include, and each Lender (and each employee, representative or other agent of any Lender) may disclose to any and all Persons, without limitation of any kind, the “tax treatment” and “tax structure” (in each case, within the meaning of Treasury Regulation Section 1.6011-4) of the transactions contemplated hereby and all materials of any kind (including opinions or other tax analyses) that are or have been provided to such Lender relating to such tax treatment or tax structure; provided that with respect to any document or similar item that in either case contains information concerning such tax treatment or tax structure of the transactions contemplated hereby as well as other information, this sentence shall only apply to such portions of the document or similar item that relate to such tax treatment or 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 (i) acknowledge and agree that JPMorgan Chase and/or its Affiliates from time to time may hold investments in, make other loans to or have other relationships with the Parent, the Borrower and their Affiliates, and (ii) waive any liability of JPMorgan Chase or such Affiliate of JPMorgan Chase to the Borrower or any Lender, respectively, arising out of or resulting from such investments, loans or relationships

other than liabilities arising out of the gross negligence or willful misconduct of JPMorgan Chase or its Affiliates.

9.14 Interest. It is the intention of the Parties to comply with applicable usury Laws; accordingly, it is agreed that notwithstanding any provisions to the contrary in any Loan Document, in no event shall any Loan Document permit the collection of interest in excess of the maximum amount permitted by such Laws. If any such excess of interest is contracted for, charged or received under any Loan Document or if the maturity of the Obligation is accelerated in whole or in part, or in the event that all or part of the principal or interest of the Obligation shall be prepaid, so that under any of such circumstances the amount of interest contracted for, charged or received under any Loan Document on the amount of principal actually outstanding from time to time under the Obligation shall exceed the maximum amount of interest permitted by applicable usury Laws, then in any such event: (i) the provisions of this Section 9.14 shall govern and control; (ii) no Person now or hereafter liable for the payment of the Obligation shall be obligated to pay the amount of such interest to the extent that it is in excess of the maximum amount of interest permitted to be contracted for by, charged to or received from the Person obligated thereon under the applicable usury Laws; (iii) any such excess which may have been collected shall be either applied as a credit against the then unpaid principal amount on the Obligation or refunded to the Person paying the same, at the holder’s option; and (iv) the effective rate of interest shall be automatically reduced to the maximum lawful rate of interest permitted to be contracted for by, charged to or received from the Person obligated thereon under the applicable usury Laws as now or hereafter construed by the courts having jurisdiction thereof. To the extent the Laws of the State of Texas are applicable for purposes of determining the “Highest Lawful Rate,” such term shall mean the “weekly rate ceiling” from time to time in effect under Chapter 303 of the Texas Finance Code, as amended from time to time in effect, subject to the Lender’s right subsequently to change such method in accordance with applicable Law. The provisions of Chapter 346 of Tex. Finance Code Ann. (Vernon 2002), regulating certain revolving credit accounts shall not govern or in any manner apply to the Obligation.

9.15 NO ORAL AGREEMENTS. THIS WRITTEN LOAN AGREEMENT, THE OTHER LOAN DOCUMENTS AND THE FEE LETTER REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

ARTICLE X

THE AGENT

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

10.2. Powers. The Agent shall have and may exercise such powers under the Loan Documents as are specifically delegated to the Agent by the terms of each thereof, together with such powers as are reasonably incidental thereto. The Agent shall have no implied duties to the Lenders, or any obligation to the Lenders to take any action thereunder except any action specifically provided by the Loan Documents to be taken by the Agent.

10.3. General Immunity. Neither the Agent nor any of its directors, officers, agents or employees shall be liable to the Borrower, the Lenders or any Lender 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 Agent nor any of its directors, officers, agents or employees shall be responsible for or have any duty to ascertain, inquire into, or verify: (a) any statement, warranty or representation made in connection with any Loan Document or any borrowing hereunder; (b) 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; (c) the satisfaction of any condition specified in Article IV, except receipt of items required to be delivered solely to the Agent; (d) the existence or possible existence of any Default or Unmatured Default; (e) the validity, enforceability, effectiveness, sufficiency or genuineness of any Loan Document or any

other instrument or writing furnished in connection therewith; (f) the value, sufficiency, creation, perfection or priority of any Lender Lien in any Collateral; or (g) 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 Agent shall have no duty to disclose to the Lenders information that is not required to be furnished by the Borrower to the Agent at such time, but is voluntarily furnished by the Borrower to the Agent (either in its capacity as Agent or in its individual capacity).

10.5. Action on Instructions of Lenders. The 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. The Lenders hereby acknowledge that the 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 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 Agent may execute any of its duties as 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, 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 Agent shall be entitled to advice of counsel concerning the contractual arrangement between the Agent and the Lenders and all matters pertaining to the Agent’s duties hereunder and under any other Loan Document.

10.7. Reliance on Documents; Counsel. The 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 Agent, which counsel may be employees of the Agent.

10.8. Agent’s Reimbursement and Indemnification. The Lenders agree to reimburse and indemnify the Agent 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 Agent is entitled to reimbursement by the Borrower under the Loan Documents, (ii) for any other expenses incurred by the 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 Agent in connection with any dispute between the 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 Agent 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 Agent in connection with any dispute between the Agent 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 Agent and (ii) any indemnification required pursuant to Section 3.5.7 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 Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Unmatured Default hereunder unless the 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 Agent receives such a notice, the Agent shall give prompt notice thereof to the Lenders.

10.10. Rights as a Lender. In the event the Agent is a Lender, the 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 Agent, and the term “Lender” or “Lenders” shall, at any time when the Agent is a Lender, unless the context otherwise indicates, include the Agent in its individual capacity. The Agent and its Affiliates may accept deposits from, lend money to, and generally engage in any kind of trust, debt, equity, hedge, swap 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.

10.11. Lender Credit Decision. Each Lender acknowledges that it has, independently and without reliance upon the Agent, the Arranger 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 the Agent, the Arranger 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 Agent. The Agent or the Syndication 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 Agent or Syndication Agent or, if no successor has been

appointed, forty-five days after the retiring Agent or Syndication Agent gives notice of its intention to resign. The Agent or the Syndication Agent may be removed at any time with or without cause by written notice received by the such Agent or Syndication 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 Agent or Syndication agent, as the case may be . If no successor Agent or Syndication Agent shall have been so appointed by the Required Lenders within thirty days after the giving notice of its intention to resign, then the resigning Agent or Syndication Agent may appoint, on behalf of the Borrower and the Lenders, a successor Agent or Syndication Agent, as the case may be. Notwithstanding the previous sentence, the Agent or the Syndication Agent may at any time without the consent of the Borrower or any Lender, appoint any of its Affiliates which is a commercial bank as a successor Agent or Syndication Agent hereunder. If the Agent or Syndication Agent has resigned or been removed and no successor Agent or Syndication Agent has been appointed, the Lenders may perform all the duties of the Agent or Syndication 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 Agent or Syndication Agent shall be deemed to be appointed hereunder until such successor Agent or Syndication Agent has accepted the appointment. Any such successor Agent or Syndication Agent shall be a commercial bank having capital and retained earnings of at least $1,000,000,000. Upon the acceptance of any appointment as Agent or Syndication Agent hereunder by a successor Agent or Syndication Agent, such successor Agent or Syndication Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the resigning or removed Agent or Syndication Agent as the case may be. Upon the effectiveness of the resignation or removal of the Agent or Syndication Agent, the resigning or removed Agent or Syndication 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 Agent or Syndication Agent, the provisions of this Article X shall continue in effect for the benefit of such Agent or Syndication Agent in respect of any actions taken or omitted to be taken by it while it was acting as the Agent or Syndication Agent hereunder and under the other Loan Documents. In the event that there is a successor to the Agent by merger, or the Agent assigns its duties and obligations to an Affiliate pursuant to this Section 10.12, then the term “Corporate Base Rate” as used in this Agreement shall mean the prime rate, base rate or other analogous rate of the new Agent.

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

10.14. Delegation to Affiliates. The Borrower and the Lenders agree that the 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 Agent is entitled under Articles IX and X.

10.15. Execution of Collateral Documents. The Lenders hereby empower and authorize the 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 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.

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 or any Guarantor 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 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 Share of the Aggregate Outstanding Credit Exposure. In case any such payment is disturbed by legal process, or otherwise, appropriate further adjustments shall be made.

11.3 Application of Collateral. The proceeds of the Collateral at any time received by the Agent following an Enforcement Action shall, when received by the Agent in cash or its equivalent, be applied by the Agent as follows:

(i) first, to the payment and satisfaction of all sums paid and costs and expenses (including reasonable attorneys’ fees and court costs) incurred by the Agent in connection herewith or under the Collateral Documents, including such amounts paid or incurred in connection with protecting, preserving or realizing upon the Collateral or enforcing any of the terms of the Collateral Documents to the extent the Agent is not reimbursed therefor by the Borrower or any Guarantor; and

(ii) second, to the payment of all remaining Obligations pro rata to each Lender with each Lender’s Pro Rata Share calculated based on a fraction, the numerator of which is the amount owing to such Lender in connection with any Loan Document and/or Rate Management Transaction and the denominator of which is the aggregate amount owing to all Lenders in connection with the Loan Documents and/or Rate Management Transactions.

The Borrower and Guarantors shall remain liable to the Agent and the Lenders for any deficiency. Any surplus remaining after the full, indefeasible payment and satisfaction of the foregoing shall be returned to the Borrower or to whomsoever a court of competent jurisdiction shall determine to be entitled thereto. After any Lender has been paid in full for all Obligations of the Borrower owed to it under the Loan Documents and/or Rate Management Transactions, such Lender shall hold in trust for, and immediately return to, the Agent any Collateral or proceeds thereof received or held hereunder.

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 Lenders and their respective successors and assigns, except that (i) the Borrower shall not have the right to assign its rights or obligations under the Loan Documents and (ii) any assignment by any Lender must be made in compliance with Section 12.3. The parties to this Agreement acknowledge that clause (ii) of this Section 12.1 relates only to absolute assignments and does not prohibit assignments creating security interests, including, without limitation, 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; 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 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 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, in the ordinary course of its business and in accordance with applicable Law, at any time sell to one or more banks or other entities (individually, a “Participant”) participating interests in any Outstanding Credit Exposure owing to 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 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 forgives principal, interest, fees or Reimbursement Obligation or reduces the interest rate or fees payable with respect to any such Credit Extension or Commitment, extends the Facility Termination Date or the expiration date for any Facility LC, postpones any date fixed for any regularly-scheduled payment of principal of or interest on any Loan in which such Participant has an interest, or any regularly-scheduled payment of fees on any such Credit Extension or Commitment, releases any Guarantor of any such Credit Extension or releases any Collateral held in the Facility LC Collateral Account (except in accordance with the terms hereof) or all or substantially all or any other Collateral, if any, securing any such Credit Extension.

12.2.3. Benefit of Setoff. The Borrower and each Guarantor 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.

12.3. Assignments.

12.3.1. Permitted Assignments. Any Lender may, in the ordinary course of its business and in accordance with applicable Law, at any time assign to one or more banks or other entities (individually, an “Eligible Assignee”) all or any part of its rights and obligations under the Loan Documents. Such assignment shall be substantially in the form of Exhibit C (the “Assignment Agreement”) or in such other form as may be agreed to by the parties thereto. The consent of the Borrower, the Agent and LC Issuer shall be required prior to an assignment becoming effective with respect to an Eligible Assignee which is not a Lender or an Affiliate thereof; provided, however, that if a Default has occurred and is continuing, the consent of the Borrower shall not be required. Such consent shall not be unreasonably withheld or delayed. Each such assignment with respect to an Eligible Assignee which is not a Lender or an Affiliate thereof shall (unless each of the Borrower and the Agent otherwise consents) be in an amount not less than the lesser of (i) $5,000,000 or (ii) the remaining amount of the assigning Lender’s Commitment (calculated as at the date of such assignment) or outstanding Credit Exposure (if the applicable Commitment has been terminated). Borrower shall not be required to pay any costs associated with any such assignment.

12.3.2. Effect; Effective Date. Upon (i) delivery to the Agent of an assignment, together with any consents required by Section 12.3.1, and (ii) payment of a $3,500 fee to the Agent for processing such assignment (unless such fee is waived by the Agent), such assignment

shall become effective on the effective date specified in such assignment. The assignment shall contain a representation by the Eligible Assignee 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 Eligible Assignee in and under the Loan Documents will not be “plan assets” under ERISA. On and after the effective date of such assignment, such Eligible Assignee 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 hereto, and no further consent or action by the Borrower, the Lenders, the LC Issuer or the Agent shall be required to release the transferor Lender with respect to the percentage of the Aggregate Commitment and Outstanding Credit Exposure assigned to such Eligible Assignee. Upon the consummation of any assignment to an Eligible Assignee pursuant to this Section 12.3.2, the transferor Lender, the Agent, the LC Issuer and the Borrower shall, if the transferor Lender or the Eligible Assignee desires that its Outstanding Credit Exposure 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 Eligible Assignee, in each case in principal amounts reflecting their respective Commitments, as adjusted pursuant to such assignment.

12.4. Dissemination of Information. The Borrower authorizes each Lender, upon prior written notice to Borrower to disclose to any Participant or Eligible Assignee 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 Parent, the Borrower and their 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 which is organized under the Laws of any jurisdiction other than 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 3.5.4.

ARTICLE XIV

COUNTERPARTS

14.1. Counterparts. This Agreement may be executed in any number of counterparts, all of which taken together shall constitute one agreement, and any of the parties hereto may execute this Agreement by signing any such counterpart.

14.2. Facsimile Documents and Signatures. For purposes of negotiating and finalizing this Agreement, if this document or any document executed in connection with it is transmitted by facsimile machine (“fax”), it shall be treated for all purposes as an original document. Additionally, the signature of any party on this document transmitted by way of a facsimile machine shall be considered for all purposes as an original signature.

NOTHING HEREIN SHALL LIMIT THE RIGHT OF THE AGENT, THE LC ISSUER OR ANY LENDER TO BRING PROCEEDINGS AGAINST THE BORROWER OR ANY GUARANTOR IN THE COURTS OF ANY OTHER JURISDICTION. ANY JUDICIAL PROCEEDING BY THE BORROWER OR ANY GUARANTOR AGAINST THE AGENT, THE LC ISSUER OR ANY LENDER OR ANY AFFILIATE OF THE AGENT, THE LC ISSUER OR ANY LENDER INVOLVING, DIRECTLY OR INDIRECTLY, ANY MATTER IN ANY WAY ARISING OUT OF, RELATED TO, OR CONNECTED WITH ANY LOAN DOCUMENT SHALL BE BROUGHT ONLY IN A COURT IN HOUSTON, TEXAS.

15.3. WAIVER OF JURY TRIAL. THE BORROWER, EACH GUARANTOR, THE AGENT, THE LC ISSUER AND EACH LENDER HEREBY WAIVE TRIAL BY JURY IN ANY JUDICIAL PROCEEDING INVOLVING, DIRECTLY OR INDIRECTLY, ANY MATTER (WHETHER SOUNDING IN TORT, CONTRACT OR OTHERWISE) IN ANY WAY ARISING OUT OF, RELATED TO, OR CONNECTED WITH ANY LOAN DOCUMENT OR THE RELATIONSHIP ESTABLISHED THEREUNDER.
