D. The Borrower, the Agent and the Banks desire to amend and restate the Original Credit Agreement in its entirety, to provide for among other things, the modification, extension and renewal of the "Revolving Commitments" under the Original Credit Agreement, which are the Commitments referred to herein. Accordingly, in consideration of the foregoing and the mutual covenants set forth herein, the parties agree that the Original Credit Agreement is hereby amended and restated in its entirety to read as follows: HOU04:43581.4 ARTICLE I DEFINITIONS, ETC.

HOU04:43581.4 ARTICLE II COMMITMENTS AND TERMS OF CREDIT Section 2.01. Commitments. (a) (i) Each Bank severally agrees, on the terms and conditions hereinafter set forth, to make one or more loans (the "Loans") to the Borrower from time to time on any Business Day during the period from the Effective Date up to, but excluding, the Maturity Date in an aggregate amount outstanding for such Bank not to exceed at any time an amount equal to such Bank's Commitment. Each Loan shall be made as either a Base Rate Loan or a Eurodollar Rate Loan and as part of a single Borrowing made on the same day by the Banks ratably according to their respective Commitment Percentages. Each Base Rate Borrowing shall be in an aggregate amount not less than $2,000,000, or, if less, the entire unfunded portion of the Total Commitment. Each Eurodollar Rate Borrowing shall be in an aggregate amount not less than $2,000,000 or an integral multiple of $1,000,000 in excess thereof. Within the limits set forth above and subject to the terms and conditions of this Agreement, the Borrower may borrow, repay pursuant to Section 2.07 or prepay pursuant to Section 2.09 and reborrow under this Section 2.01(a). (ii) The Issuing Bank agrees, on the terms and conditions hereinafter set forth, to issue standby or commercial letters of credit for the account of the Borrower (the "Letters of Credit") from time to time on any one or more Business Days during the period from the Effective Date up to, but excluding, the ninetieth (90th) day preceding the Maturity Date in an aggregate amount for all Outstanding Letters of Credit not exceeding at any time the Letter of Credit Limit. Each Letter of Credit shall be denominated in Dollars, shall expire no later than the date set forth in Section 2.03(a), and shall be in such form as approved from time to time by the Issuing Bank and the Borrower. Each Bank severally agrees, on the terms and conditions hereinafter set forth, to purchase participations in the Letters of Credit issued by the Issuing Bank pursuant to this Agreement in an amount equal to such Bank's Commitment Percentage of the face amount of such Letter of Credit. Upon the issuance of each Letter of Credit, the Issuing Bank shall be deemed, without further action by any party hereto, to have sold to each Bank, and each Bank shall be deemed, without further action by any party hereto, to have purchased from the Issuing Bank, a participation, to the extent of such Bank's Commitment Percentage, in such Letter of Credit, the obligations of the Issuing Bank thereunder and in the reimbursement obligations of the Borrower due in respect of drawings made under such Letter of Credit. Subject to the terms of the Loan Documents, the Banks will execute any other documents the Issuing Bank may reasonably request to evidence the purchase of such participation. On each day during the period commencing with the issuance by the Issuing Bank of any Letter of Credit and ending on the date when such Letter of Credit shall have expired or been terminated, and, irrespective of whether such Letter of Credit has expired or terminated if such Letter of Credit has been drawn upon and the amount so drawn has not been reimbursed to the Issuing Bank, the Commitment of each Bank shall be deemed to be utilized for all purposes hereof in an amount equal to such Bank's Commitment Percentage of the Outstanding Letters of Credit. HOU04:43581.4 (iii) Notwithstanding any other term or provision hereof (A) no Loan shall be made and no Letter of Credit shall be issued if after giving effect to the making of such Loan or issuance of such Letter of Credit the aggregate amount of Credit Outstanding would exceed the Total Commitment and (B) no Letter of Credit shall be issued if after giving effect to the issuance of such Letter of Credit the aggregate amount of Outstanding Letters of Credit would exceed the Letter of Credit Limit. (b) Loans of more than one Type may be outstanding at the same time, but the Borrower shall not be entitled to request any Borrowing or to Convert Loans comprising any Borrowing into Loans of another Type, if after giving effect to such Borrowing or Conversion, as the case may be, any Bank would have outstanding (i) at any one time more than four (4) different Types of Loans. Loans having different Interest Periods, regardless of whether they commence on the same date or have the same type of interest rate, shall be considered different Types of Loans; provided, however, that all Base Rate Loans are the same type of Loan so long as they remain Base Rate Loans. Section 2.02. Borrowing Procedures; Conversions. (a) (i) Each Borrowing shall be made upon the written, telecopied or facsimile transmitted request of the Borrower, given to the Agent not later than 11:00 a.m. (New York time) on (A) the third Business Day prior to the proposed Borrowing Date in the case of a Eurodollar Rate Borrowing, or (B) the Business Day immediately preceding the proposed Borrowing Date in the case of a Base Rate Borrowing, and the Agent shall give each other member of the Bank Group prompt notice of such request by telecopier, telex or cable. (ii) Each request for a Borrowing (a "Borrowing Request") made by the Borrower shall be in substantially the form of Exhibit 2.02(a), specifying therein (A) the Borrowing Date for such Borrowing, (B) the Type of Loans comprising such Borrowing, (C) the aggregate amount of such Borrowing and (D) in the case of a Eurodollar Rate Borrowing, the Interest Period for the Loans comprising such Borrowing. Each Bank shall, before 12:00 Noon (New York time) on the date of such Borrowing, make available for the account of its Applicable Lending Office to the Agent at its address referred to in Section 9.03, in same day funds, such Bank's ratable portion of such Borrowing. After the Agent's receipt of such funds and upon fulfillment of the applicable conditions set forth in Article III, the Agent will make such funds available to the Borrower at the Agent's aforesaid address. Each Borrowing Request shall be irrevocable and binding on the Borrower. (b) Unless the Agent shall have received notice from a Bank prior to the date of any Borrowing that such Bank will not make available to the Agent such Bank's ratable portion of such Borrowing, the Agent may assume that such Bank has made such portion available to the Agent on the date of such Borrowing in accordance with subsection (a) of this Section 2.02 and the Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Bank shall not have HOU04:43581.4 so made such ratable portion available to the Agent, such Bank and the Borrower severally agree to repay to the Agent forthwith on demand such corresponding amount, together with interest thereon for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Agent at (i) in the case of the Borrower, the interest rate applicable at the time to the Loans comprising such Borrowing and (ii) in the case of such Bank, the Federal Funds Rate. If such Bank shall repay to the Agent such corresponding amount, such amount so repaid shall constitute such Bank's Loan as part of such Borrowing for purposes of this Agreement, and Borrower shall be relieved of Borrower's obligation to repay such amount under this Section 2.02(b). The failure of any Bank to make the Loan to be made by it as part of any Borrowing shall not relieve any other Bank of its obligation, if any, hereunder to make its Loan on the date of such Borrowing or any subsequent Borrowing Date, but no Bank shall be responsible for the failure of any other Bank to make the Loan to be made by such other Bank on the date of any Borrowing. (c) The Borrower may, subject to the terms of this Agreement, on any Business Day, upon written, telecopied or facsimile transmitted notice to the Agent, given not later than 11:00 a.m. (New York time) on (i) the third Business Day prior to the proposed Conversion Date in the case of a Conversion of Loans into Eurodollar Rate Loans, or (ii) the Business Day immediately preceding the proposed Conversion Date in the case of a Conversion of Loans into Base Rate Loans, Convert Loans into Borrowings comprised of Loans of another Type, and the Agent shall promptly transmit the contents of such notice to each other member of the Bank Group by telecopier, telex or cable. Notwithstanding any other term or provision hereof, after giving effect to any such Conversion, the size of all Borrowings outstanding hereunder, and the number of different Types of Loans outstanding hereunder, shall conform to the requirements of Section 2.01. In the event of any Conversion of Eurodollar Rate Loans on any day other than the last day of the Interest Period applicable thereto, the Borrower shall be obligated to reimburse the Banks in respect thereof pursuant to Section 2.13. Each notice of a Conversion (a "Conversion Notice") given by the Borrower shall be in substantially the form of Exhibit 2.02(c) hereto, specifying therein (A) the Conversion Date for such Conversion, (B) the Loans to be Converted, (C) the Type of Loans to which such Loans are to be Converted and (D) in the case of a Conversion into Eurodollar Rate Loans, the Interest Period for such Converted Loans. If the Borrower shall fail to give a timely Conversion Notice conforming to the requirements of this Agreement with respect to any Eurodollar Rate Loans prior to the expiration of the Interest Period applicable thereto, such Eurodollar Rate Loans shall, automatically on the last day of such Interest Period, be Converted into Base Rate Loans. Section 2.03. Issuing and Reimbursing the Letters of Credit. (a) Each Letter of Credit shall, subject to the terms of this Agreement, be issued upon the written or facsimile transmitted request (an original of which shall be immediately forwarded by overnight courier to the Issuing Bank) of the Borrower given to the Agent not later than 11:00 a.m. (New York time) on the third Business Day prior to the proposed date of issuance of such Letter of HOU04:43581.4 Credit. Each such request for a Letter of Credit (a "Letter of Credit Request") made by the Borrower shall be in substantially the form of Exhibit 2.03 hereto and shall specify the Business Day on which such Letter of Credit is to be issued, the beneficiary of such Letter of Credit, the amount of such Letter of Credit, the draw conditions applicable thereto and shall provide for an expiry date which is not later than thirty days prior to the Maturity Date. (b) Upon satisfaction of the applicable terms and conditions set forth in Article III, the Issuing Bank shall issue such Letter of Credit to the specified beneficiary not later than the close of business (New York time) on the date so specified. The Issuing Bank shall provide each other member of the Bank Group with a copy of each Letter of Credit so issued, but any failure of the Issuing Bank to provide such Persons with a copy of such Letter of Credit shall not in any way affect the Borrower's obligation to reimburse the Issuing Bank for any amount paid by the Issuing Bank under any Letter of Credit or the Banks' obligation to reimburse the Issuing Bank for such amount, to the extent provided herein, in the event the Borrower fails to do so. Each such Letter of Credit shall (i) provide for the payment of drafts or other forms of payment to be presented for honor thereunder by the beneficiary in accordance with the terms thereon, at sight when accompanied by the documents described therein and (ii) be subject to the Uniform Customs and Practice for Documentary Credits (1993 Revision), International Chamber of Commerce Publication No. 500, (and any subsequent revisions thereof approved by a Congress of the International Chamber of Commerce and adhered to by the Issuing Bank) (the "UCP") and shall, as to matters not governed by the UCP, be governed by, and construed and interpreted in accordance with, the governing law specified in this Agreement. (c) Upon presentment to the Issuing Bank of any draft for honor under any Letter of Credit by the beneficiary thereof and the determination by the Issuing Bank that such draft is in order, the Issuing Bank shall give prompt notice (a "Reimbursement Notice") to the Borrower of (i) the Letter of Credit to which such Reimbursement Notice relates, (ii) the amounts to be paid on account of such draft (the "Reimbursement Amount") and (iii) the date on which such amounts are to be paid (the "Reimbursement Date"), but any failure to so notify the Borrower shall not in any way affect the Borrower's obligations to reimburse the Issuing Bank for any amount paid by the Issuing Bank under any Letter of Credit. (d) Upon receipt of any Reimbursement Notice, the Borrower shall reimburse the Issuing Bank by forthwith paying to the Agent for the benefit of the Issuing Bank (who shall promptly notify the Issuing Bank of such payment) no later than 10:00 a.m. (New York time) on the Reimbursement Date specified in such Reimbursement Notice an amount equal to the Reimbursement Amount specified in such Reimbursement Notice, and, if the Issuing Bank is not fully reimbursed by the Borrower on such Reimbursement Date, together with interest from such Reimbursement Date until such reimbursement is made by the Borrower at a fluctuating rate per annum equal to the lesser of (i) the Highest Lawful Rate and (ii) the Base Rate in effect during the time such reimbursement HOU04:43581.4 obligation remains unpaid plus the Applicable Margin for Base Rate Loans from such Reimbursement Date until the third day immediately following the delivery of such Reimbursement Notice by the Issuing Bank to Borrower and (B) thereafter, the Default Rate. To the extent availability may then exist, and upon compliance with the relevant terms and conditions of this Agreement, the Borrower may repay any or all of the obligations described in this paragraph by requesting a Borrowing and applying the proceeds thereof accordingly. (e) If the Borrower shall fail to reimburse the Issuing Bank for any payment by the Issuing Bank under a Letter of Credit by 12:00 noon. (New York time) on the Reimbursement Date specified in the Reimbursement Notice related thereto, the Agent shall give prompt notice thereof to each other member of the Bank Group. Upon receipt of such notice, each Bank shall, notwithstanding any other provision of this Agreement (including the occurrence and continuance of a Default or an Event of Default), make available to the Agent for the benefit of the Issuing Bank an amount equal to its Commitment Percentage of the Reimbursement Amount specified in the related Reimbursement Notice no later than the close of business on such Reimbursement Date. If such amount is not in fact made available to the Agent by such Bank on such Reimbursement Date, such Bank shall pay to the Agent for the account of the Issuing Bank, on demand made by the Issuing Bank, in addition to such amount, interest on such amount for the number of days that elapse from such Reimbursement Date to the date on which the amount equal to such Bank's Commitment Percentage of such Reimbursement Amount becomes immediately available to the Issuing Bank at a rate per annum equal to the average daily Federal Funds Rate for such days. Any amount received by the Agent or the Issuing Bank from the Borrower in respect of a draft honored under a Letter of Credit after one or more of the Banks have made funds available for the payment of such draft pursuant to this paragraph shall be paid over by the Agent or the Issuing Bank, as the case may be, to the Banks, pro rata according to the amounts so made available by the Banks, promptly upon receipt by the Agent or the Issuing Bank of such amount. Nothing in this Agreement shall diminish the Borrower's obligation under this Agreement to provide the funds for the payment of, or on demand to reimburse the Issuing Bank for payment of, any draft presented to, and duly honored by, the Issuing Bank under any Letter of Credit. (f) In order to induce the issuance of Letters of Credit by the Issuing Bank and the purchase of participations therein by the Banks, the Borrower irrevocably agrees (i) that the obligation of the Borrower to reimburse the Issuing Bank for amounts paid by the Issuing Bank under any Letter of Credit, including accrued interest thereon, as set forth herein is absolute and unconditional, (ii) that no member of the Bank Group shall be responsible or liable for, and the Borrower's unconditional obligation to reimburse the Issuing Bank through the Agent for amounts paid by the Issuing Bank on account of drafts honored under the Letters of Credit shall not be affected by, any circumstance, act or omission whatsoever relating to any Letter of Credit, whether or not known to any member of the Bank Group, unless such circumstance, act or omission results in the wrongful payment or the wrongful dishonor of any Letter of Credit HOU04:43581.4 or is otherwise the result of the gross negligence or willful misconduct of such member of the Bank Group, (iii) that any action taken or omitted to be taken by any member of the Bank Group under or in connection with any Letter of Credit or any related draft, document or property shall be binding on the Borrower and shall not put any member of the Bank Group under any resulting liability to the Borrower, unless such action or omission results in the wrongful payment or the wrongful dishonor of any Letter of Credit or otherwise is the result of the gross negligence or willful misconduct of such member of the Bank Group and (iv) to indemnify, defend and hold each member of the Bank Group harmless from and against any and all liabilities, damages, claims or reasonable expenses (including reasonable attorneys' fees and amounts paid in settlement) arising out of or based on any Letter of Credit, except to the extent the same is the result of the wrongful payment or the wrongful dishonor of any Letter of Credit or is otherwise the result of the gross negligence or willful misconduct of the Person seeking indemnity hereunder, IT BEING THE EXPRESS INTENTION OF THE BORROWER THAT EACH MEMBER OF THE BANK GROUP SHALL BE INDEMNIFIED AND HELD HARMLESS AGAINST ANY AND ALL LIABILITIES, CLAIMS, OR REASONABLE EXPENSES ARISING OUT OF OR RESULTING FROM THE ORDINARY NEGLIGENCE (WHETHER SOLE OR CONTRIBUTORY) OF SUCH MEMBER OF THE BANK GROUP. The Borrower hereby waives presentment for payment and notice of dishonor, protest and notice of protest with respect to drafts honored under the Letters of Credit. (g) The provisions of this Agreement and the other Loan Documents concerning collateral, standard of care of the Issuing Bank, timing of payments, interest rates applicable to any reimbursement obligation relating to any Letter of Credit, any representations, warranties, covenants, events of default, remedies and governing law shall supersede in their entirety the provisions of any Letter of Credit application relating to such matters. In the event any other provision of any Letter of Credit application is inconsistent with, or in conflict of any provision of this Agreement or any Loan Documents, the provisions of this Agreement or the Loan Documents shall govern. Section 2.04. Borrowing Base. (a) The Borrowing Base in effect from time to time shall represent the maximum amount (subject to the Total Commitment) of Loans that the Banks will make to the Borrower. During the period from and after the Effective Date until the Borrowing Base is redetermined in accordance with this Section, the amount of the Borrowing Base shall be $20,000,000. The Borrowing Base shall be determined in accordance with Section 2.04(b) by the Agent and approved by all of the Banks or the Majority Banks, as applicable. The Borrowing Base is subject to redetermination in accordance with Section 2.04(d). Upon any redetermination of the Borrowing Base, such redetermination shall remain in effect until the next successive date that the redetermined Borrowing Base becomes effective subject to the notice requirements specified in Section 2.04(e) for both the scheduled redetermination and unscheduled redeterminations. So long as any part of the Commitments are in effect and until all of the Loans outstanding hereunder are paid in full, this Agreement shall be governed by the then effective Borrowing Base. HOU04:43581.4 (b) The Agent will after receipt of the most recent Reserve Report delivered to the Banks under Section 5.10, and such other data and supplemental information as may from time to time be reasonably requested by the Agent, but in no event later than May 1 and November 1 of each year commencing May 1, 1997, redetermine the Borrowing Base based on such Reserve Report. The Agent and each Bank will redetermine the Borrowing Base in accordance with their respective normal and customary oil and gas lending criteria as such exist at that particular time taking into account all of the assets and liabilities of the Borrower and its Subsidiaries. The Agent and each Bank, in their sole discretion, may make reasonable adjustments to the rates, volumes and prices and other assumptions set forth in the Reserve Reports and such other data and supplemental information. Each redetermination of the Borrowing Base which would increase the Borrowing Base must be approved by all of the Banks, and each other redetermination of the Borrowing Base must be approved by the Majority Banks. Failure of a Bank to object to a redetermination within 14 days after notice of such redetermination is given to such Bank by the Agent shall be deemed an approval of such redetermination by such Bank. (c) The Agent may exclude any Oil and Gas Property or portion of production therefrom from the Borrowing Base, at any time, because the status of title to such Oil or Gas Property is not reasonably satisfactory to Agent or because such Oil and Gas Property is not subject to a first priority lien in favor of the Agent as security for the Obligations. (d) So long as any of the Commitments are in effect and until payment in full of all Loans hereunder, effective on or about May 1 and November 1 of each year commencing May 1, 1997 (each being a "Scheduled Redetermination Date"), the Agent with the approval of all of the Banks or the Majority Banks, as applicable, shall redetermine the amount of the Borrowing Base in accordance with Section 2.04(b). In addition, at any time after the first scheduled Redetermination Date, (i) the Borrower may request a redetermination of the Borrowing Base on its own initiation at any time in connection with a proposed acquisition of Oil and Gas Properties with a fair market value in excess of $10,000,000 and at one additional time during any consecutive twelve (12) month period, and (ii) the Agent and Majority Banks may each initiate a redetermination of the Borrowing Base at any time as they so elect; provided, however, that the Agent and Majority Banks may each initiate only one such unscheduled redetermination during any consecutive twelve (12) month period (each being an "Unscheduled Redetermination Date"). Any redetermination of the Borrowing Base on an Unscheduled Redetermination Date shall be in accordance with Section 2.04(b). (e) The Agent shall promptly notify in writing the Borrower and the Banks of the new Borrowing Base. Such redetermination of the Borrowing Base shall not be in effect until notice is given to the Borrower. HOU04:43581.4 Section 2.05. The Notes. The Loans made by each Bank shall be evidenced by a single Note issued to such Bank by the Borrower, (i) dated the date of this Agreement (or such other date as may be specified in Section 9.02), (ii) payable to the order of such Bank in a principal amount equal to such Bank's Commitment Percentage of the Aggregate Maximum Commitment and (iii) otherwise duly completed. Each Loan made by a Bank to the Borrower and all payments made on account of the principal amount thereof shall be entered by such Bank in its records or on the schedule (or a continuation thereof) attached to the Note of such Bank, provided, that prior to any transfer of any such Note, such Bank shall endorse the amount and maturity of any outstanding Loans on the schedule (or a continuation thereof) attached to such Note. Section 2.06. Reduction of the Commitments. (a) The Borrower shall have the right, upon at least three Business Days' notice to the Agent to terminate in whole or reduce ratably in part the unused portions of the Aggregate Maximum Commitment; provided, that each partial reduction in the Aggregate Maximum Commitment shall be in the aggregate amount of $1,000,000 or an integral multiple of $1,000,000 in excess thereof. Any such reduction or termination shall be irrevocable by the Borrower. (b) On each Commitment Reduction Date, the Reducing Commitment Amount shall automatically be reduced by an amount equal to 8.2% of the Reducing Commitment Amount as of the first Commitment Reduction Date. On the Maturity Date the Commitment of each Bank shall automatically be reduced to zero. Section 2.07. Mandatory Repayment of Loans. (a) The Borrower shall from time to time repay the Loans comprising part of the same Borrowing or provide cover for Outstanding Letters of Credit in such amounts as shall be necessary so that at all times the Credit Outstanding shall not be in excess of the Total Commitment. Except to the extent that repayment or cover is required to be made in three equal monthly installments under Section 2.07(b), any repayment or cover required by this Section 2.07(a) shall be due and payable on the date such repayment or cover obligation accrues pursuant to the preceding sentence. (b) The Borrower shall from time to time repay the Loans comprising part of the same Borrowing or provide cover for Outstanding Letters of Credit (as provided below) in whole or ratably in part in an amount equal to the excess of (i) the Credit Outstanding as of any redetermination of the Borrowing Base pursuant to Section 2.04 over (ii) the Borrowing Base as of such date. Any repayment or cover required by this Section 2.07(b) shall be due and payable in three equal monthly installments, each in an amount equal to one third (1/3rd) of the original amount of such excess, commencing on the last day of the calendar month immediately following such redetermination of the Borrowing Base and continuing on the same day of each subsequent calendar month. HOU04:43581.4 (c) In the event that the Borrower shall be required pursuant to this Section 2.07 to repay Loans or provide cover for Outstanding Letters of Credit, the Borrower shall make such repayment and provide such cover in the following order: (i) first, pay the amount of all unreimbursed drawings under the Letters of Credit, (ii) second, repay the principal of the Loans and (iii) third, provide cover for Letters of Credit. Cover for Letters of Credit shall be effected by paying to the Agent immediately available funds, to be held by the Agent in an account under the sole dominion and control of the Agent, for the benefit of the Bank Group, as security for the obligations of the Borrower under the Loan Documents until the earlier of (A) the occurrence in this Section 2.07 which necessitated such cover no longer exists or (B) such time as the Letters of Credit have been terminated and all obligations of the Borrower to the Bank Group (including the Issuing Bank) in respect thereof have been paid in full, at which time the Agent shall remit the amount of such cover, in immediately available funds, at the direction or instruction of the Borrower. Any funds delivered pursuant to the preceding sentence shall be placed in an interest bearing account selected by the Agent and so long as no Default has occurred and is continuing, any accrued interest on such funds shall be distributed monthly to the Borrower. (d) All outstanding Loans shall be fully due and payable on the Maturity Date, together with any unpaid interest accrued thereon. (e) Each repayment of Loans required by this Section 2.07 shall be accompanied by payment of accrued interest to the date of such payment on the principal amount paid. In the event of any payment of a Eurodollar Rate Loan, the Borrower shall be obligated to reimburse the Banks in respect thereof pursuant to Section 2.13. All principal payments required by this Section 2.07 shall first be applied to Base Rate Borrowings, and second to Eurodollar Rate Borrowings. Section 2.08. Interest Accrual, Payments. (a) Accrual and Payment. Subject to the provisions of Section 9.13, the Borrower shall pay interest on the unpaid principal amount of each Loan made by each Bank from the date of such Loan until such principal amount shall be paid in full, on the dates and at the rates per annum specified as follows: (i) Base Rate Loans. If such Loan is a Base Rate Loan, a rate per annum equal at all times to the lesser of (A) the Highest Lawful Rate and (B) the Base Rate in effect from time to time plus the Applicable Margin in effect from time to time, and unpaid accrued interest on such Loans shall be due and payable on each Quarterly Payment Date and on the date such Base Rate Loan shall be paid in full; provided, however, that if the Borrower has not been notified by the Agent of the amount of such accrued interest at least one Business Day prior to such date, such accrued interest shall be due and payable one Business Day after the Borrower is notified of such amount. (ii) Eurodollar Rate Loans. If such Loan is a Eurodollar Rate Loan, a rate per annum equal at HOU04:43581.4 all times during the Interest Period for such Loan to the lesser of (A) the Highest Lawful Rate and (B) the sum of the Eurodollar Rate for such Interest Period plus the Applicable Margin in effect as of the first day of such Interest Period, and unpaid accrued interest on such Loans shall be due and payable on the last day of such Interest Period; provided, however, that if the Borrower has not been notified by the Agent of the amount of such accrued interest at least one Business Day prior to such date, such accrued interest shall be due and payable one Business Day after the Borrower is notified of such amount. Any amount of principal or, to the extent permitted by applicable law, interest which is not paid when due (whether at stated maturity, by acceleration or otherwise) shall bear interest from the date on which such amount is due until such amount is paid in full, at a rate per annum equal at all times to the lesser of (A) the Highest Lawful Rate and (B) the Base Rate in effect from time to time during the applicable period plus the Applicable Margin in effect from time to time during such period plus two percent (2%) (the "Default Rate"), payable on demand. (b) Determination of Interest Rates. (i) The Agent shall give prompt notice to the Borrower and each other member of the Bank Group of the applicable interest rate determined by the Agent hereunder for each Borrowing. Each determination by the Agent of an interest rate hereunder shall be conclusive and binding for all purposes, absent manifest error. (ii) If the Majority Banks shall, at least one Business Day before the date of any requested Eurodollar Rate Borrowing, notify the Agent that the Eurodollar Rate applicable to such Borrowing will not adequately reflect the cost to such Banks of making, funding or maintaining their respective Eurodollar Rate Loans for such Borrowing, the right of the Borrower to select Eurodollar Rate Loans for such Borrowing or any subsequent Borrowing shall be suspended until the Agent shall notify the Borrower and each other member of the Bank Group that the circumstances causing such suspension no longer exist, and each Loan comprising such Borrowing shall be made as, or Converted into, as applicable, a Base Rate Loan. (c) Applicable Margin. As used in this Agreement and the other Loan Documents, "Applicable Margin" means, as to Loans consisting of a single Borrowing, a rate per annum determined by reference to the Type of Loans comprising such Borrowing as follows: (i) if the aggregate amount of Loans outstanding as of the date of determination is equal to or greater than 66.7% of the Total Commitment as of such date, then such rate per annum shall be one-half of one percent (1/2%) for Base Rate Loans, and two percent (2%) for Eurodollar Rate Loans; (ii) if the aggregate amount of Loans outstanding as HOU04:43581.4 of the date of determination is equal to or greater than 33.3% but less than 66.7% of the Total Commitment as of such date, such rate per annum shall be one-half of one percent (1/2%) for Base Rate Loans and one and three-quarters (1 3/4%) for Eurodollar Rate Loans; and (iii) if the aggregate amount of Loans outstanding as of the date of determination is less than 33.3% of the Total Commitment as of such date, such rate per annum shall be one-half of one percent (1/2%) for Base Rate Loans, and one and one-quarter percent (1 1/4%) for Eurodollar Rate Loans. Section 2.09. Optional Prepayments. (a) The Borrower may, from time to time on any Business Day, upon notice to the Agent stating the proposed date and aggregate principal amount thereof, and if such notice is given the Borrower shall, prepay the outstanding principal amount of the Base Rate Loans (without premium or penalty) comprising part of the same Borrowing in whole or ratably in part; provided, that any partial prepayment of such Base Rate Loans shall be in an aggregate principal amount of not less than $500,000. The Borrower may from time to time upon at least three Business Days' notice to the Agent stating the proposed date and the aggregate principal amount thereof, and if such notice is given the Borrower shall, prepay the outstanding principal amount of the Eurodollar Rate Loans comprising part of the same Borrowing in whole or ratably in part; provided, that any partial prepayment of such Eurodollar Rate Loans shall be in an aggregate principal amount of not less than $500,000 or an integral multiple of $100,000 in excess thereof. (b) Each prepayment of Loans made pursuant to this Section 2.09 shall be accompanied by a payment of accrued interest to the date of such prepayment on the principal amount prepaid. In the event of any prepayment of a Eurodollar Rate Loan, the Borrower shall be obligated to reimburse the Banks in respect thereof pursuant to Section 2.13. Section 2.10. Payments, Notice of Certain Repayments and Computations. (a) All payments of principal, interest, commitment fees and other amounts hereunder, under the Notes and the other Loan Documents (other than Bank Group Derivatives) shall be made in Dollars to the Agent at its address specified in Section 9.03 for the account of each of the Banks, in immediately available funds not later than 11:00 a.m. (New York time) on the date when due. Upon receipt of such payments, the Agent will promptly cause to be distributed like funds relating to the payment of principal or interest or commitment fees ratably (other than amounts payable pursuant to Section 2.12, Section 2.13, Section 2.14 or Section 2.15) to the Banks, for the account of their respective Applicable Lending Offices, and like funds relating to the payment of any other amount payable to any Bank, to such Bank for the account of its Applicable Lending Office, in each case to be applied in accordance with the terms of this Agreement. (b) Unless the Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Banks under the HOU04:43581.4 Loan Documents that the Borrower will not make such payment in full, the Agent may assume that the Borrower has made such payment in full to the Agent on such date and the Agent may, in reliance upon such assumption, cause to be distributed to each Bank on such due date an amount equal to the amount then due such Bank. If and to the extent the Borrower shall not have made such payment in full to the Agent each Bank shall repay to the Agent forthwith on demand such amount distributed to such Bank, together with interest thereon for each day from the date such amount is distributed to such Bank until the date such Bank repays such amount to the Agent at the Federal Funds Rate. (c) All payments by the Borrower of the fees payable to the Agent or the Issuing Bank shall be made in Dollars directly to such Person at its address specified in Section 9.03 in immediately available funds not later than 11:00 a.m. (New York time) on the date when due. (d) All computations of interest based on the Base Rate shall be made on the basis of a year of 365 or 366 days, as the case may be, and all computations of interest based on the Eurodollar Rate or the Federal Funds Rate, as well as commitment fees, shall be made on the basis of a year of 360 days (unless use of a 360 day year would cause the interest contracted for, charged or received hereunder to exceed the Highest Lawful Rate, in which case such computations shall be made on the basis of a year of 365 or 366 days, as the case may be), in each case for the actual number of days (including the first day but excluding the last day) occurring in the period for which such interest or commitment fees are payable. (e) Whenever any payment under the Loan Documents shall be stated to be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day, and such extension of time shall in such case be included in the computation of payment of interest or commitment fee, as the case may be; provided, if such extension would cause payment of interest on or principal of Eurodollar Rate Loans to be made in the next following calendar month, such payment shall be made on the immediately preceding Business Day. (f) If any Bank shall obtain any payment (whether voluntary, involuntary, through the exercise of any right of setoff, or otherwise) on account of the Loans made by it (other than pursuant to Section 2.08(b), Section 2.12, Section 2.13, Section 2.14 or Section 2.15), or payments by the Issuing Bank made pursuant to Section 2.03, in excess of its ratable share of payments on account of the Loans or payments by the Issuing Bank made pursuant to Section 2.03, obtained by all the Banks, such Bank shall forthwith purchase from the other Banks such participations in the Loans made by such other Banks, or the reimbursement obligations in respect of the payments by the Issuing Bank made pursuant to Section 2.03, as the case may be, as shall be necessary to cause such purchasing Bank to share the excess payment ratably with each of them. The Borrower agrees that any Bank so purchasing a participation from another Bank pursuant to this Section 2.10(f) may, to the fullest extent HOU04:43581.4 permitted by law and this Agreement, exercise all its rights of payment (including the right of setoff) with respect to such participation as fully as if such Bank were the direct creditor of the Borrower in the amount of such participation. Section 2.11. Fees. (a) Subject to the provisions of Section 9.13, the Borrower agrees to pay to each Bank a commitment fee equal to one-half of one percent (1/2%) per annum on the average unused portion of the Commitment of such Bank in effect from time to time for the period from the Execution Date to, but excluding, the Maturity Date (or if earlier, the termination in full of the Commitment). Accrued commitment fees shall be due and payable in arrears on each Quarterly Payment Date in each year, on the date of any reduction or termination of the Commitment of such Bank and on the Maturity Date (or if earlier, the termination in full of the Commitment); provided that if the Borrower has not been notified by Agent of the amount of such fee at least one Business Day prior to any such date, such fee shall be due and payable one Business Day after the Borrower is notified by Agent of such amount, and shall be computed for the period commencing with the day to which such fee was last paid (or, in the case of the first commitment fee payment date, for the period commencing with and including the Execution Date) to the date such fee is due and payable. Subject to the provisions of Section 9.13, so long as any Obligation shall remain outstanding or any Banks shall have any Commitment hereunder the Borrower shall pay the Agent an annual agency fee of $25,000 on the Execution Date and on each anniversary date thereof. (b) (i) The Borrower agrees to pay the Issuing Bank a fee in respect of each Letter of Credit issued for the account of the Borrower (the "L/C Fees"). With respect to each Letter of Credit, Borrower agrees to pay an L/C Fee, for the period from the date of issuance of such Letter of Credit in an amount equal to 1 1/4 % per annum on the outstanding face amount of such Letter of Credit. All L/C Fees shall be paid in immediately available funds and shall based on a 360 day year and actual days elapsed. Accrued L/C Fees for each Letter of Credit shall be due and payable in arrears on each Quarterly Payment Date and on the termination or expiration date of such Letter of Credit (or if earlier, the termination in full of the Commitments). The Issuing Bank shall be entitled to retain, solely for the Issuing Bank's account, .15% per annum as an issuing fee on all Letters of Credit (the "Retained L/C Fees") and pay to the Agent for the pro rata benefit of the Banks all remaining L/C Fees. In addition to the L/C Fees, the Borrower shall pay the Issuing Bank, solely for the Issuing Bank's account, its customary administrative service charges relating to the issuance of, amendment to, payment under and transfer of any Letters of Credit. Such amounts to be due and payable when such services are rendered by the Issuing Bank. (ii) On each Quarterly Payment Date, the Issuing Bank shall pay the aggregate amount of all L/C Fees collected by the Issuing Bank during the quarterly period then ended, net of the amount of any Retained L/C Fees retained by the Issuing Bank for such period, to the Agent. Upon receipt by the Agent, the Agent shall distribute such net amount of L/C Fees to the Banks ratably according to their respective Commitment Percentages. Within ten (10) HOU04:43581.4 Business Days after each Quarterly Payment Date, the Issuing Bank shall give a written report to the other members of the Bank Group specifying the gross amount of all L/C Fees collected by the Issuing Bank during the quarterly period then ended, the amount of all Retained L/C Fees, and the net amount of such L/C Fees delivered to the Agent for distribution to the Banks. Section 2.12. Setoff, Counterclaims and Taxes. (a) All payments of principal, interest, expenses, reimbursements, compensation, commitment fees, L/C Fees, arrangement fees or administration fees and any other amount from time to time due under the Notes, this Agreement or any other Loan Document shall be made by the Borrower without setoff or counterclaim and shall be made free and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto, excluding, in the case of each member of the Bank Group, taxes imposed on its income, and franchise taxes imposed on it, by the jurisdiction under the laws of which such member of the Bank Group is organized or any political subdivision thereof and, in the case of each Bank, taxes imposed on its income, and franchise taxes imposed on it, by the jurisdiction of such Bank's Applicable Lending Office or any political subdivision thereof (all such non-excluded taxes, levies, imposts, deductions, charges, withholdings and liabilities being hereinafter referred to as "Taxes"). If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder or under any Loan Document to any member of the Bank Group, (i) the sum payable shall be increased as may be necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 2.12) such member of the Bank Group receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable law. (b) In addition, the Borrower agrees to pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies which arise from any payment made hereunder or under the Notes or the other Loan Documents or from the execution, delivery or registration of, or otherwise with respect to, this Agreement, the Notes or the other Loan Documents (hereinafter referred to as "Other Taxes"). (c) The Borrower will indemnify each member of the Bank Group for the full amount of Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this Section 2.12) paid, by such member of the Bank Group (whether paid on its own behalf or on behalf of any other member of the Bank Group) and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto. This indemnification shall be made within 10 days from the date such member of the Bank Group makes written demand therefor. HOU04:43581.4 (d) Within 30 days after the date of any payment of Taxes, the Borrower will furnish to the Agent, at its address referred to in Section 9.03, the original or a certified copy of a receipt evidencing payment thereof. If no Taxes are payable in respect of any payment hereunder or under the Notes or the other Loan Documents, upon the reasonable request of the Agent, the Borrower will furnish to the Agent at its address referred to in Section 9.03, a certificate from each appropriate taxing authority, or an opinion of counsel acceptable to the Agent stating that such payment is exempt from or not subject to Taxes. (e) Without prejudice to the survival of any other agreement of the Borrower hereunder, the agreements and obligations of the Borrower contained in this Section 2.12 shall survive the payment in full of the Credit Outstanding and all other amounts owing under the other Loan Documents. The provisions of this Section 2.12 are in all respects subject to Section 9.13 hereof. (f) Each Bank represents and warrants to the Agent, the Issuing Bank, the Borrower and the Guarantor that such Bank is either (i) a corporation organized under the laws of the United States or a state thereof or (ii) entitled to complete exemption from United States withholding tax imposed on or with respect to any payments, including fees, to be made to it pursuant to this Agreement and the other Loan Documents (x) under an applicable provision of a tax convention to which the United States is a party or (y) because it is acting through a branch, agency or office in the United States and any payment to be received by it hereunder is effectively connected with a trade or business in the United States. Upon becoming a party to this Agreement (whether by assignment or as an original signatory hereto), and in any event, from time to time upon the request of the Agent or the Borrower, each Bank which is not a corporation organized under the laws of the United States or any state thereof shall deliver to the Agent and the Borrower such forms, certificates or other instruments as may be required by the Agent in order to establish that such Bank is entitled to complete exemption from United States withholding taxes imposed on or with respect to any payments, including fees, to be made to such Bank under this Agreement and the other Loan Documents. Each Bank also agrees to deliver to the Borrower and the Agent and such other supplemental forms as may at any time be required as a result of the passage of time or changes in applicable law or regulation in order to confirm or maintain in effect its entitlement to exemption from U.S. withholding tax on any payments hereunder; provided, that the circumstances of the Bank at the relevant time and applicable laws permit it to do so. If a Bank determines, as a result of any change in either (1) applicable law, regulation or treaty, or in any official application thereof or (2) its circumstances, that it is unable to submit any form or certificate that it is obligated to submit pursuant to this Section 2.12(f), or that it is required to withdraw or cancel any such form or certificate previously submitted, it shall promptly notify the Borrower and the Agent of such fact. If a Bank is organized under the laws of a jurisdiction outside the United States, and the Borrower and the Agent have not received forms, certificates or other instruments indicating to their satisfaction that all payments to be made to such Bank hereunder or under the Guaranty are not subject to United States withholding tax or the Agent otherwise has reason to believe HOU04:43581.4 that such Bank is subject to U.S. withholding tax, the Borrower and the Guarantor shall withhold taxes from such payments at the applicable statutory rate. Each Bank shall indemnify and hold the Borrower, the Guarantor, the Issuing Bank and the Agent harmless from any United States taxes, penalties, interest and other expenses, costs and losses incurred or payable by them as a result of either (A) such Bank's failure to submit any form or certificate that it is required to provide pursuant to this Section 2.12(f) or (B) reliance by the Borrower, the Guarantor, the Issuing Bank or the Agent on any such form or certificate which such Bank has provided to them pursuant to this Section 2.12(f). HOU04:43581.4 Section 2.13. Funding Losses. The Borrower shall indemnify each Bank against any loss or reasonable expense (including, but not limited to, any loss or reasonable expense sustained or incurred or to be sustained or incurred in liquidating or reemploying deposits from third parties acquired to effect or maintain such Loan or any part thereof as a Eurodollar Rate Loan) which such Bank may sustain or incur as a consequence of (a) any failure by the Borrower to fulfill on the date of any Borrowing hereunder the applicable conditions set forth in Article III, (b) any failure by the Borrower to borrow hereunder, or to Convert Loans hereunder or to cause a Letter of Credit to be issued after a Borrowing Request, Letter of Credit Request or Conversion Notice, respectively, has been given, (c) any payment, prepayment or Conversion of a Eurodollar Rate Loan required or permitted by any other provisions of this Agreement, including, without limitation, payments made due to the acceleration of the maturity of the Notes pursuant to Section 7.01, or otherwise made on a date other than the last day of the applicable Interest Period, (d) any default in the payment or prepayment of the principal amount of any Loan or any part thereof or interest accrued thereon, as and when due and payable (at the due date thereof, by notice of prepayment or otherwise) or (e) the occurrence of an Event of Default. Such loss or reasonable expense shall include, without limitation, an amount equal to the excess, if any, as determined by each Bank of (i) its cost of obtaining the funds for the Loan being paid, prepaid or Converted or not borrowed or Converted (based on the Eurodollar Rate applicable thereto) for the period from the date of such payment, prepayment or Conversion or failure to borrow or Convert to the last day of the Interest Period for such Loan (or, in the case of a failure to borrow or Convert, the Interest Period for the Loan which would have commenced on the date of such failure to borrow or Convert) over (ii) the amount of interest (as estimated by such Bank) that would be realized by such Bank in reemploying the funds so paid, prepaid or Converted or not borrowed or Converted for such period or Interest Period, as the case may be. A certificate of each Bank setting forth any amount or amounts which such Bank is entitled to receive pursuant to this Section 2.13 shall be delivered to the Borrower (with a copy to the Agent and the Co-Agent) and shall be conclusive, if made in good faith, absent manifest error. The Borrower shall pay to the Agent for the account of each Bank the amount shown as due on any certificate within 10 days after its receipt of the same. Notwithstanding the foregoing, in no event shall any Bank be permitted to receive any compensation hereunder constituting interest in excess of the Highest Lawful Rate. Without prejudice to the survival of any other obligations of the Borrower hereunder, the obligations of the Borrower under this Section 2.13 shall survive the termination of this Agreement and/or the payment or assignment of any of the Notes. Section 2.14. Change of Law. (a) If at any time any Bank determines in good faith (which determination shall be conclusive) that any change in any applicable law, rule or regulation or in the interpretation, application or administration thereof makes it unlawful, or any central bank or other Governmental Authority asserts that it is unlawful, for such Bank or its foreign branch or branches to fund or maintain any Eurodollar Rate Loan (any of the foregoing determinations being a "Eurodollar Event"), then, such Bank, at its option, may: (i) declare that Eurodollar Rate Loans will no longer be made HOU04:43581.4 or maintained by such Bank, whereupon the right of the Borrower to select Eurodollar Rate Loans for any Borrowing shall be suspended until such Bank shall notify the Agent that the circumstances causing such Eurodollar Event no longer exist; (ii) with respect to any Eurodollar Rate Loans of such Bank then outstanding, require that all such Eurodollar Rate Loans be Converted to Base Rate Loans, in which event all such Eurodollar Rate Loans shall automatically be Converted into Base Rate Loans on the effective date of such notice and all payments or prepayments of principal that would have otherwise been applied to repay such Converted Eurodollar Rate Loans shall instead be applied to repay the Base Rate Loans resulting from such Conversion; and/or (iii) with respect to any Eurodollar Rate Loans requested of such Bank but not yet made as or Converted into such, require that such Eurodollar Rate Loans be made as or Converted into, as applicable, Base Rate Loans. (b) Upon the occurrence of any Eurodollar Event, and at any time thereafter so long as such Eurodollar Event shall continue, such Bank may exercise its aforesaid option by giving written notice thereof to the Agent and the Borrower, such notice to be effective upon receipt thereof by the Borrower. Any Conversion of any Eurodollar Rate Loan which is required under this Section 2.14 shall be made, together with accrued and unpaid interest and all other amounts payable to such Bank under this Agreement with respect to such Converted Loan (including, without limitation, amounts payable pursuant to Section 2.13 hereof), on the date stated in the notice to the Borrower referred to above. Section 2.15. Increased Costs. (a) If, due to either (i) the introduction of or any change in or in the interpretation of any law or regulation or (ii) the compliance with any guideline issued or request made by any central bank or other Governmental Authority (whether or not having the force of law) after the date hereof, there shall be any increase in the cost to any Bank of agreeing to make or making, funding or maintaining Eurodollar Rate Loans, then the Borrower shall from time to time, subject to the provisions of Section 9.13, pay to the Agent for the account of such Bank additional amounts sufficient to compensate such Bank for such increased cost upon demand by such Bank. (b) If any Bank shall have determined in good faith that any law, rule, regulation or guideline adopted after the date hereof pursuant to or arising out of the July 1988 report of the Basle Committee on Banking Regulations and Supervisory Practices entitled "International Convergence of Capital Measurement and Capital Standards" or that the adoption after the date hereof of any applicable law, rule, regulation or guideline regarding capital adequacy, or any change after the date hereof in any of the foregoing or in the interpretation or administration thereof by any central bank or other Governmental Authority charged with the interpretation or administration thereof, or compliance by such Bank (or any lending office of such Bank) with any request or directive regarding capital adequacy (whether or not having the force of law) of any such Governmental Authority or comparable agency, affects or would affect the amount of capital required or expected to be maintained by such Bank or any corporation controlling such Bank, then the Borrower shall from HOU04:43581.4 time to time, subject to the provisions of Section 9.13, pay to such Bank upon demand additional amounts sufficient to compensate such Bank or such corporation in the light of such circumstances, to the extent that such Bank reasonably determines such increase in capital to be allocable to the existence of such Bank's Commitment hereunder. (c) If any law, executive order or regulation is adopted or interpreted by any central bank or other Governmental Authority so as to affect any of the Borrower's obligations or the compensation to any Bank or the Issuing Bank in respect of the Letters of Credit or the cost to such Bank or the Issuing Bank of establishing and/or maintaining the Letters of Credit (or any participation therein), then the Borrower shall from time to time upon demand, subject to the provisions of Section 9.13, reimburse or indemnify such Bank or the Issuing Bank, as the case may be, with respect thereto so that such Bank or the Issuing Bank, as the case may be, shall be in the same position as if there had been no such adoption or interpretation. (d) Each Bank or the Issuing Bank, as the case may be, will notify the Borrower of any event occurring after the date of this Agreement which will entitle such Bank or the Issuing Bank, as the case may be, to compensation pursuant to this Section 2.15 as promptly as practicable after such Bank obtains knowledge of the occurrence of such event. A certificate of such Bank or the Issuing Bank, as the case may be, setting forth in reasonable detail (i) such amount or amounts as shall be necessary to compensate such Bank (or participating banks or other entities pursuant to Section 9.02) or the Issuing Bank, as the case may be, as specified above and (ii) the calculation of such amount or amounts shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay to such Bank or to the Issuing Bank, as the case may be, the amount shown as due on any such certificate within ten (10) days after its receipt of the same. The failure of any Bank or the Issuing Bank to demand compensation for any increased costs or reduction in amounts received or receivable or reduction in return on capital shall not constitute a waiver of the right of such Bank, any other Bank or the Issuing Bank, to demand compensation for any increased costs or reduction in amounts received or receivable or reduction in return on capital as such rights are set forth herein. The protection of this Section 2.15 shall be available to the Issuing Bank and the Banks regardless of any possible contention of invalidity or inapplicability of law, regulation or condition which shall have been imposed.

ARTICLE IV REPRESENTATIONS AND WARRANTIES In order to induce the Bank Group to enter into this Agreement, the Borrower hereby represents and warrants to the Bank Group as follows: Section 4.01. Corporate Existence. Each of the Borrower and its Subsidiaries is a corporation duly organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation, and is duly qualified or licensed to transact business as a foreign corporation and is in good standing under the laws of each jurisdiction in which the conduct of its operations or the ownership or leasing of its properties requires such qualification or licensing, except where the failure to be so qualified or licensed will not have a Material Adverse Effect on such Person. Schedule 4.01 is a complete list of the Borrower's Subsidiaries. Section 4.02. Corporate Authority; Binding Obligations. Each of the Borrower and its Subsidiaries has all requisite corporate power and HOU04:43581.4 authority to conduct its business, to own, operate and encumber its Property, and to execute, deliver and perform all of its obligations under the Loan Documents executed by, or to be executed by, such Person. The execution, delivery and performance of each of the Loan Documents to which the Borrower or any of its Subsidiaries is a party and the consummation of the transactions contemplated thereby have been duly authorized by all necessary corporate action. Each of the Loan Documents to which the Borrower or any of its Subsidiaries is a party has been duly executed and delivered by such Person, is in full force and effect and constitutes the legal, valid and binding obligation of such Person, enforceable against it in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting the enforcement of creditor's rights generally and general principles of equity. The Security Documents create valid Liens in the collateral described therein, securing the secured obligations described therein. Section 4.03. No Conflict. The execution, delivery and performance by the Borrower or any of its Subsidiaries of each Loan Document to which such Person is a party and the consummation of each of the transactions contemplated thereby do not and shall not, by the lapse of time, the giving of notice or otherwise: (a) constitute a violation of any Requirement of Law or a breach of any provision contained in the articles or certificate of incorporation or bylaws of such Person, or any shareholder agreement pertaining to such Person, or contained in any material agreement, instrument or document to which it is now a party or by which it or its properties is bound, except for such violations or breaches that will not have a Material Adverse Effect on any such Person; or (b) result in or require the creation or imposition of any Lien whatsoever upon any of the properties or assets of the Borrower or any of its Subsidiaries (other than Excepted Liens and Liens in favor of the Agent arising pursuant to the Loan Documents). Section 4.04. No Consent. No authorization, consent, approval, license, or exemption of or filing or registration with, any Governmental Authority or any other Person, which has not been obtained, was, is or will be necessary for the valid execution, delivery or performance by the Borrower or any of its Subsidiaries of any of the Loan Documents to which it is a party and the consummation of each of the transactions contemplated thereby or the Borrower's or any of its Subsidiaries' ownership, use or operation of any of their Properties other than (a) those listed on Schedule 4.04 and (b) those that the failure to obtain, file or make will not have a Material Adverse Effect on any such Person. Section 4.05. No Defaults or Violations of Law. No Default or Event of Default has occurred and is continuing. No default (or event or circumstance occurred which, but for the passage of time or the giving of notice, or both, would constitute a default) has occurred and is continuing with respect to any note, indenture, loan agreement, mortgage, lease, deed or other agreement to which the Borrower or any of its Subsidiaries is a party or by which any of them or their Properties is bound, except for such defaults that will not have a Material Adverse Effect on the Borrower or any of its Subsidiaries. Neither the Borrower nor HOU04:43581.4 any of its Subsidiaries is in violation of any applicable Requirement of Law except for such violations that will not have a Material Adverse Effect on any such Person. Section 4.06. Financial Position. (a) Prior to the Execution Date, the Borrower has furnished to the Agent and the Bank Group audited financials of the Borrower and its Subsidiaries as of December 31, 1995 and unaudited financials of the Borrower as of June 30, 1996. The audited financials referred to in the previous sentence have been prepared in accordance with generally accepted accounting principles consistently applied throughout the periods involved and present fairly the financial condition of the Borrower and its Subsidiaries as of the dates thereof and the results of their operations for the periods then ended. No event has occurred since June 30, 1996 that could reasonably be expected to have a Material Adverse Effect on the Borrower or any of its Subsidiaries. (b) Except as fully reflected in the audited financials referred to in paragraph (a) of this Section 4.06, as of the date hereof, there are no liabilities or obligations of the Borrower or any of its Subsidiaries of any nature whatsoever (whether absolute, accrued, contingent or otherwise and whether or not due) which, either individually or in aggregate, would have a Material Adverse Effect on the Borrower or any of its Subsidiaries. Section 4.07. Litigation. Except as set out in Schedule 4.07, there are no actions, suits or proceedings pending or, to the knowledge of the Borrower threatened against or affecting the Borrower or any of its Subsidiaries, or the Properties of any such Person, before or by any Governmental Authority or other Person, which, if determined adversely to such Person could have a Material Adverse Effect on any such Person. Section 4.08. Use of Proceeds. (a) The Borrower's uses of the proceeds of the Loans and of the Letters of Credit are, and will continue to be, legal and proper corporate uses (duly authorized by Borrower's board of directors), and such uses are consistent with the terms of the Loan Documents, including, without limitation, Section 5.09, and all Requirements of Law. (b) Neither the Borrower nor any of its Subsidiaries is engaged in the business of extending credit for the purpose of purchasing or carrying margin stock (within the meaning of Regulation U), and no part of the proceeds of any Loan or Letter of Credit will be used, directly or indirectly, (i) to purchase or carry any margin stock or to extend credit to others for the purpose of purchasing or carrying any margin stock or (ii) for the purpose of purchasing, carrying or trading in any securities under such circumstances as to involve the Borrower or any of its Subsidiaries in a violation of Regulation X. Section 4.09. Governmental Regulation. Neither the Borrower nor any of its Subsidiaries is subject to regulation under the Public Utility Holding Company Act, as amended, the Investment Company Act of 1940, as amended, or any other Requirement of Law such that the ability of any such HOU04:43581.4 Person to incur indebtedness is limited or its ability to consummate the transactions contemplated by this Agreement, the other Loan Documents or any document executed in connection therewith is impaired. Section 4.10. Disclosure. The schedules, documents, exhibits, reports, certificates and other written statements and information furnished by or on behalf of the Borrower or any of its Subsidiaries to the Bank Group do not contain any Material misstatement of fact, or omit to state a Material fact necessary in order to make the statements contained therein, in light of the circumstances under which they were made, not misleading. Neither the Borrower nor any of its Subsidiaries has intentionally withheld any fact known to it which has or is reasonably likely to have a Material Adverse Effect on the Borrower or any of its Subsidiaries. Section 4.11. ERISA. (a) The Borrower, and each ERISA Affiliate and Subsidiary have operated and administered each Pension Plan and Other Benefit Plan in compliance with all applicable laws, except for such instances of noncompliance as have not resulted in and could not reasonably be expected to result in a Material Adverse Effect. Neither the Borrower nor any ERISA Affiliate or Subsidiary has incurred any liability pursuant to Title I or IV of ERISA or the penalty or excise tax provisions of the Internal Revenue Code relating to employee benefit plans (as defined in Section 3 of ERISA), and no event, transaction or condition has occurred or exists or is threatened that could reasonably be expected to result in the incurrence of any such liability by the Borrower or any ERISA Affiliate or Subsidiary, or in the imposition of any Lien on any of the rights, properties or assets of the Borrower or any ERISA Affiliate or Subsidiary, in either case pursuant to Title I or IV of ERISA or to such penalty or excise tax provisions or to Section 401(a)(29) or 412 of the Internal Revenue Code, other than such liabilities or Liens as would not be, individually or in the aggregate, Material. (b) The present value of the aggregate benefit liabilities under each Pension Plan subject to Title IV of ERISA, determined as of the end of such Pension Plan's most recently ended plan year on the basis of the actuarial assumptions specified for funding purposes in such Pension Plan's most recent actuarial valuation report, did not exceed the aggregate current value of the assets of such Pension Plan allocable to such benefit liabilities. The term "benefit liabilities" has the meaning specified in section 4001 of ERISA and the terms "current value" and "present value" have the meaning specified in Section 3 of ERISA. (c) The Borrower and its ERISA Affiliates and Subsidiaries do not currently and have never had any liability or obligation with respect to any liabilities (and are not subject to contingent withdrawal liabilities) under section 4201 or 4204 of any Multiemployer Plan. (d) The expected post-retirement benefit obligation (determined as of the last day of the Borrower's most recently ended fiscal year in accordance with Financial HOU04:43581.4 Accounting Standards Board Statement No. 106, without regard to liabilities attributable to continuation coverage mandated by section 4980B of the Internal Revenue Code ("COBRA")) of the Borrower and its ERISA Affiliates and Subsidiaries is not Material and, except as modified by COBRA, such obligations can be unilaterally terminated at any time by the Borrower, or its ERISA Affiliates and Subsidiaries without any Material liability. Section 4.12. Payment of Taxes. The Borrower has filed, and has caused each of its Subsidiaries to file, all federal, state and local tax returns and other reports that the Borrower and each such Subsidiary are required by law to file and have paid all taxes and other similar charges that are due and payable pursuant to such returns and reports, except to the extent any of the same may be contested in good faith by appropriate proceedings promptly initiated and diligently conducted, and with respect to which adequate reserves have been set aside on the books of such Person in accordance with generally accepted accounting principles. Section 4.13. Title and Liens. (a) Except as set out in Schedule 4.13 the Borrower and its Subsidiaries have good and defensible title to its Properties, free and clear of all Liens except Liens permitted by Section 6.02. Except as set forth in Schedule 4.13, after giving full effect to the Excepted Liens, the Borrower owns the net interests in production attributable to the Oil and Gas Properties reflected in the Initial Reserve Report and the ownership of such Oil and Gas Properties shall not in any material respect obligate the Borrower to bear the costs and expenses relating to the maintenance, development and operations of each such Oil and Gas Property in an amount in excess of the working interest of each Oil and Gas Property set forth in the Initial Reserve Report. Further, upon delivery of each Reserve Report, the statements made in the preceding sentence shall be true with respect to such furnished Reserve Reports including the ownership of the Oil and Gas Properties set forth therein. To the best of the Borrower's knowledge, all information contained in the Initial Reserve Report is true and correct in all material respects as of the date thereof. (b) All material leases and agreements necessary for the conduct of the business of the Borrower and its Subsidiaries are valid and subsisting, in full force and effect and, to the knowledge of the Borrower, there exists no default or event or circumstance which with the giving of notice or the passage of time or both would give rise to a default under any such lease or leases, which would affect in any material respect the conduct of the business of the Borrower and its Subsidiaries. (c) The rights, properties and other assets presently owned, leased or licensed by the Borrower and its Subsidiaries including, without limitation, all easements and rights of way, include all rights, properties and other assets necessary to permit the Borrower and its Subsidiaries to conduct their business in all material respects in the same manner as their business has been conducted prior to the date hereof. HOU04:43581.4 (d) All of the assets and properties of the Borrower and its Subsidiaries which are reasonably necessary for the operation of its business are in good working condition and are maintained in accordance with prudent business standards. Section 4.14. Gas Imbalances. As of the date of this Agreement, except as set forth in Schedule 4.14 or on the most recent certificate delivered pursuant to Section 5.10(c), on a net basis there are no gas imbalances, take or pay or other prepayments with respect to the Borrower's Oil and Gas Properties which would require the Borrower to deliver Hydrocarbons produced from the Oil and Gas Properties at some future time without then or thereafter receiving full payment therefor exceeding a market value of $100,000 in the aggregate.

Upon the occurrence of an Event of Default, the Agent may exercise all rights and remedies granted under the Security Documents, including the right to obtain possession of all such Hydrocarbon proceeds then held by the Borrower or to receive directly from the purchasers of production all other such Hydrocarbon proceeds. In no case shall any failure, whether purposed or inadvertent, by the Agent to collect directly any such Hydrocarbon proceeds constitute in any way a waiver, remission or release of any of its rights under the Security Documents, nor shall any release of any such Hydrocarbon proceeds by the Agent to the Borrower constitute a waiver, remission or release of any other such Hydrocarbon proceeds or of any rights of the Agent to collect other such proceeds thereafter. Section 7.05. Application of Proceeds After Acceleration. If any Event of Default shall have occurred and be continuing, and if the Obligations have become due and payable, all cash collateral held by the Agent under this Agreement and the proceeds of any sale, disposition or other realization by the Agent upon the Mortgaged Property (or any portion thereof) pursuant to the Security Documents, shall be distributed in whole or in part by the Agent in the following order of priority, unless otherwise directed by all of the Banks: First, to the Agent and the Co-Agent, ratably, in an amount equal to all costs and expenses of the Agent and the Co-Agent due and payable as of the date of such distribution; Second, to the Banks, ratably, in an amount equal to all accrued interest and fees owing to the Banks under the Credit Agreement due and payable as of the date of such distribution; provided, however, that in case such proceeds shall be insufficient to pay in full all such Obligations, then to the payment thereof to the Banks, ratably, in proportion to its percentage of the sum of the aggregate amounts of all such Obligations; HOU04:43581.4 Third, to the Banks, ratably, in an amount equal to all unreimbursed drawings under the Letters of Credit owing to the Banks due and payable as of the date of such distribution; provided, however, that in case such proceeds shall be insufficient to pay in full all such Obligations, then to the payment thereof to the Banks, ratably, in proportion to its percentage of the sum of the aggregate amounts of all such Obligations; Fourth, to the Banks, ratably, in an amount equal to the principal of all Loans owing to the Banks under the Credit Agreement due and payable as of the date of such distribution; provided, however, that in case such proceeds shall be insufficient to pay in full all such Obligations, then to the payment thereof to the Banks, ratably, in proportion to its percentage of the sum of the aggregate amounts of all such Obligations; Fifth, to the Agent as cash collateral in an amount equal to all Outstanding Letters of Credit; Sixth, to the Banks, ratably, in an amount equal to all amounts owing to the Banks under all Bank Group Derivatives due and payable as of the date of such distribution; provided, however, that in case such proceeds shall be insufficient to pay in full all such Obligations, then to the payment thereof to the Banks, ratably, in proportion to its percentage of the sum of the aggregate amounts of all such Obligations; Seventh, to the Banks in an amount equal to all other Obligations due and payable as of the date of such distribution; provided, however, that in case such proceeds shall be insufficient to pay in full all such Obligations, then to the payment thereof to the Banks, ratably, in proportion to its percentage of the sum of the aggregate amounts of all such Obligations; and Eighth, to the extent of any surplus, to the Borrower, as its interests may appear, except as may be provided otherwise by law; it being understood that the Borrower shall remain liable to the extent of any deficiency between the amount of the proceeds of the Mortgaged Property and the aggregate of the sums referred to in clauses First through Seventh above.

Each Bank hereby appoints and authorizes the Agent and the Issuing Bank to take such action in such capacity on such Bank's behalf and to exercise such powers under this Agreement and the other Loan Documents as are delegated to the Agent or the Issuing Bank by the terms hereof and thereof, together with such powers as are reasonably incidental thereto. As to any matters not expressly provided for by this Agreement (including, without limitation, enforcement or collection of the Notes or of amounts owing under the other Loan Documents), neither the Agent nor the Issuing Bank shall be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Majority Banks, and such instructions shall be binding upon all Banks and any other holders of Notes; provided, however, that neither the Agent nor the Issuing Bank shall be required to take any action which exposes it to personal liability or which is contrary to the Loan Documents or applicable law. Each of the Agent and the Issuing Bank is hereby expressly authorized on behalf of the other members of the Bank Group, without hereby limiting any implied authority, (a) to receive on behalf of each of the other members of the Bank Group any payment of principal of or interest on the Loans outstanding hereunder, any Letters of Credit and all other amounts accrued hereunder paid to such Persons, and promptly to distribute to each other member of the Bank Group its proper share of all payments so received; (b) to give notice within a reasonable time on behalf of each other member of the Bank Group to the Borrower of any Default or Event of Default specified in this Agreement of which the Agent has actual knowledge as provided in Section 8.09; (c) to distribute to the other members of the Bank Group copies of all notices, agreements and other material as provided for in this Agreement as received by such Person; and (d) to distribute to the Borrower any and all requests, demands and approvals received by such Person from any other member of the Bank Group. Nothing herein contained shall be construed to constitute the Agent or the Issuing Bank as a trustee for any holder of the Notes or of a participation therein, nor to impose on the Agent any duties or obligations other than those expressly provided for in the Loan Documents. Section 8.02. Reliance, Etc. None of the Agent, the Issuing Bank, their Affiliates and their respective directors, officers, agents or employees shall be liable for any action taken or omitted to be taken by it or them under or in connection with this Agreement, except for its or their own gross negligence or willful misconduct. Without limitation of the generality of the foregoing, the Agent and the Issuing Bank: (a) may treat the payee of any Note as the holder thereof until the Agent receives and accepts an Assignment and Acceptance entered into by the Bank which is the payee of such Note, as assignor, and an Eligible Assignee, as assignee, as provided in Section 9.02; (b) may consult with legal counsel (including counsel for the Borrower), independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts; (c) makes no HOU04:43581.4 warranty or representation to any Bank and shall not be responsible to any Bank for any statements, warranties or representations (whether written or oral) made in or in connection with this Agreement or the other Loan Documents; (d) shall not have any duty to ascertain or to inquire as to the performance or observance of any of the terms, covenants or conditions of this Agreement or the other Loan Documents on the part of the Borrower or any other Person or to inspect the property (including the books and records) of the Borrower or any other Person; (e) shall not be responsible to any Bank for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of any Loan Document, any collateral provided for therein, or any other instrument or document furnished pursuant thereto; and (f) shall incur no liability under or in respect of this Agreement by acting upon any notice, consent, certificate or other instrument or writing (which may be by telecopier, telegram, cable or telex) believed by it to be genuine and signed or sent by the proper party or parties. None of the Agent, the Issuing Bank, their Affiliates and their respective directors, officers, employees or agents shall have any responsibility to the Borrower on account of the failure or delay in performance or breach by any Bank of any of its obligations hereunder or to any Bank on account of the failure of or delay in performance or breach by any other Bank or the Borrower of any of its obligations hereunder or in connection herewith; provided, however, that the foregoing shall not relieve BTCo of its obligations as a Bank hereunder. Section 8.03. BTCo and Affiliates. Without limiting the right of any other Bank to engage in any business transactions with the Borrower or any of its Affiliates, with respect to its Commitment, the Loans made by it, the Notes issued to it and its interest in the Outstanding Letters of Credit, Bankers Trust Company ("BTCo") shall have the same rights and powers under this Agreement as any other Bank and may exercise the same as though it were not the Issuing Bank or the Agent; and the term "Bank" or "Banks" shall, unless otherwise expressly indicated, include BTCo in its individual capacity. BTCo, or any of its Affiliates, may be engaged in, or may hereafter engage in, one or more loan, Letter of Credit, leasing, derivative or other financing activities not the subject of the Loan Documents (collectively, the "Other Financings") with the Borrower or any of its Affiliates, or may act as trustee on behalf of, or depositary for, or otherwise engage in other business transactions with the Borrower or any of its Affiliates (all Other Financings and other such business transactions being collectively, the "Other Activities") with no responsibility to account therefor to the Banks. Without limiting the rights and remedies of the Banks specifically set forth in the Loan Documents, no other Bank shall have any interest in (a) any Other Activities, (b) any present or future guarantee by or for the account of the Borrower not contemplated or included in the Loan Documents, (c) any present or future offset exercised by BTCo in respect of any such Other Activities, (d) any present or future property taken as security for any such Other Activities or (e) any property now or hereafter in the possession or control of BTCo which may be or become security for the obligations of the Borrower under the Loan Documents by reason of the general description of indebtedness secured, or of property, contained in any other agreements, documents or instruments related to such Other Activities; provided, that if any HOU04:43581.4 payment in respect of such guarantees or such property or the proceeds thereof shall be applied to reduction of the obligations evidenced hereunder and by the Notes, then each Bank shall be entitled to share in such application according to its pro rata portion of such obligations. Section 8.04. Bank Credit Decision. Each Bank acknowledges that it has, independently and without reliance upon any other member of the Bank Group and based on the financial statements referred to in Section 4.06 and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Bank also acknowledges that it will, independently and without reliance upon any other member of the Bank Group 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. Section 8.05. Indemnification. The Banks agree to indemnify each of the Agent and the Issuing Bank, the Co-Agent, its Affiliates or any of their respective directors, officers, agents or employees (to the extent not reimbursed by the Borrower), ratably according to its Commitment Percentages, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by, or asserted against any such Person in any way relating to or arising out of this Agreement or the other Loan Documents or any action taken or omitted by any such Person under this Agreement or the other Loan Documents, provided, that no Bank shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from such Person's gross negligence or willful misconduct. IT IS THE EXPRESS INTENTION OF THE PARTIES HERETO THAT THE AGENT, THE CO-AGENT, THE ISSUING BANK AND THEIR AFFILIATES AND THEIR DIRECTORS, OFFICERS, AGENTS OR EMPLOYERS SHALL BE INDEMNIFIED AND HELD HARMLESS AGAINST ANY AND ALL LIABILITIES, OBLIGATIONS, LOSSES, DAMAGES, PENALTIES, ACTIONS, JUDGMENTS, SUITS, COSTS, EXPENSES OR DISBURSEMENTS OF ANY KIND ARISING OUT OF OR RESULTING FROM THE ORDINARY NEGLIGENCE (WHETHER SOLE OR CONTRIBUTORY) OF SUCH PERSON. Neither the Agent, the Issuing Bank nor the Co-Agent shall be required to do any act hereunder or under any other document or instrument delivered hereunder or in connection herewith or take any action toward the execution or enforcement of the agencies hereby created, or to prosecute or defend any suit in respect of this Agreement or the Loan Documents or any collateral security, unless indemnified to its satisfaction by the holders of the Notes against loss, cost, liability, and expense. If any indemnity furnished to the Agent, the Issuing Bank and the Co-Agent for any purpose is, in the opinion of such Person insufficient or becomes impaired, such Person may call for additional indemnity and not commence or cease to do the acts indemnified against until such additional indemnity is furnished. Without limitation of the foregoing, each Bank agrees to reimburse the Agent, the Issuing Bank or the Co-Agent promptly upon demand for its ratable share of any out-of-pocket expenses (including HOU04:43581.4 counsel fees) incurred by such Person in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement and the other Loan Documents, to the extent that the Agent, the Issuing Bank or the Co-Agent is not reimbursed for such expenses by the Borrower.

Each of the Agent and the Issuing Bank may, and upon the written instruction of the Majority Banks shall, enforce on behalf of the Banks any claims which the Agent and/or the Banks may have against any such employee, agent or attorney-in-fact, and any recovery therefrom shall be applied for the pro rata benefit of the Banks. Section 8.07. Successor Agent. The Agent may resign at any time by giving written notice thereof to the other members of the Bank Group and the Borrower and may be removed at any time with or without cause by the Majority Banks.

If no successor Agent shall have been so appointed by the Majority Banks, and shall have accepted such appointment, within thirty (30) days after the retiring Agent's giving of notice of resignation or the Majority Banks' removal of the retiring Agent, then the retiring Agent may, on behalf of the Banks, appoint a successor Agent, which shall be a commercial bank or corporation organized under the laws of the United States of America or of any State thereof and having a combined capital and surplus of at least $500,000,000. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations under this Agreement, subject to the requirement that such retiring Agent will execute such documents and take such actions as may be necessary or desirable to cause the successor Agent to be vested with all such rights, powers, privileges and duties.

Each Bank will take reasonable steps to protect the confidentiality of any information concerning the Borrower or its Subsidiaries provided to a respective participant or assignee and known by such Bank to be confidential, and, if requested by the Borrower, such Bank will identify the prospective assignees and participants that have received such information.

All covenants contained in the Loan Documents shall be given independent effect so that if a particular action or condition is not permitted by any of such covenants, the fact that such action or condition would be permitted by an exception to, or otherwise be within the limitations of, another covenant shall not avoid the occurrence of a Default or an Event of Default if such action is taken or condition exists. Section 9.07. Survival of Representations and Warranties. All representations and warranties contained in this Agreement and the other Loan Documents or made in writing by the Borrower or the Guarantor in connection herewith or therewith, shall survive the execution and delivery of this Agreement, the Notes and the other Loan Documents, the expiration of the Letters of Credit and the repayment of the Loans.

Section 9.11. Governing Law. THIS AGREEMENT (INCLUDING THE VALIDITY AND ENFORCEABILITY HEREOF) SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK. Chapter 15, Subtitle 3, Title 79, of the Revised Civil Statutes of Texas, 1925, as amended (relating to revolving loans and revolving triparty accounts), shall not apply to this Agreement or the Notes or the transactions contemplated hereby. HOU04:43581.4 Section 9.12. Submission to Jurisdiction. (a) The Borrower hereby irrevocably submits to the non-exclusive jurisdiction of any New York state court located in the Borough of Manhattan, City and State of New York, or any federal court located in the Southern District of New York over any action or proceeding arising out of or relating to this Agreement or any of the other Loan Documents, and each of the Borrower irrevocably agrees that all claims in respect of such action or proceeding may be heard and determined in such New York state or federal court; provided, nothing in this Section 9.12 is intended to waive the right of any member of the Bank Group to remove any such action or proceeding commenced in any such New York state court to an appropriate New York federal court to the extent the basis for such removal exists under applicable law. The Borrower hereby irrevocably appoints CT Corporation (the "Process Agent"), with an office on the date hereof at 1633 Broadway, New York, New York 10019, as its agent to receive on behalf of it and its properties service of copies of the summons and complaint and any other process which may be served in any such action or proceeding. Such service may be made by mailing by certified mail a copy of such process to the Borrower in care of the Process Agent at the Process Agent's above address, with a copy to such Person at its address specified herein and each of the Borrower hereby irrevocably authorizes and directs the Process Agent to accept such service on its behalf. As an alternative method of service, each of the Borrower also irrevocably consents to the service of any and all process in any such action or proceeding by the mailing by certified mail of copies of such process to it at its address specified herein. The Borrower agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. (b) Nothing in this Section 9.12 shall affect the right of any member of the Bank Group to serve legal process in any other manner permitted by law or affect the right of any member of the Bank Group to bring any action or proceeding against the Borrower, or such Person's properties, in the courts of any other jurisdiction. Section 9.13. Limitation on Interest. Each provision in this Agreement and each other Loan Document is expressly limited so that in no event whatsoever shall the amount paid, or otherwise agreed to be paid, by the Borrower for the use, forbearance or detention of the money to be loaned under this Agreement or any other Loan Document or otherwise (including any sums paid as required by any covenant or obligation contained herein or in any other Loan Document which is for the use, forbearance or detention of such money), exceed that amount of money which would cause the effective rate of interest to exceed the Highest Lawful Rate, and all amounts owed under this Agreement and each other Loan Document shall be held to be subject to reduction to the effect that such amounts so paid or agreed to be paid which are for the use, forbearance or detention of money under this Agreement or such Loan Document shall in no event exceed that amount of money which would cause the effective rate of interest to exceed the Highest Lawful Rate. To the extent that the Highest Lawful Rate applicable to a Bank is at any time determined by Texas law, such rate shall be the "indicated rate ceiling" described in Section (a)(1) of Article 1.04 of HOU04:43581.4 Chapter 1, Subtitle 1, Title 79, of the Revised Civil Statutes of Texas, 1925, as amended; provided, to the extent permitted by such Article, the Banks from time to time by notice from the Agent to Borrower may revise the aforesaid election of such interest rate ceiling as such ceiling affects the then-current or future balances of the Loans outstanding under the Notes. Notwithstanding any provision in this Agreement or any other Loan Document to the contrary, if the maturity of the Notes or the obligations in respect of the other Loan Documents are accelerated for any reason, or in the event of prepayment of all or any portion of the Notes or the obligations in respect of the other Loan Documents by the Borrower or in any other event, earned interest on the Loans and such other obligations of the Borrower may never exceed the maximum amount permitted by applicable law, and any unearned interest otherwise payable under the Notes or the obligations in respect of the other Loan Documents that is in excess of the maximum amount permitted by applicable law shall be cancelled automatically as of the date of such acceleration or prepayment or other such event and, if theretofore paid, shall be credited on the principal of the Notes or, if the principal of the Notes has been paid in full, held as collateral for any contingent or unmatured obligation of the Borrower, or, if there are no contingent or unmatured obligations of the Borrower then outstanding, refunded to the Borrower. In determining whether or not the interest paid or payable, under any specific contingency, exceeds the Highest Lawful Rate, the Borrower and the Banks shall, to the maximum extent permitted by applicable law, amortize, prorate, allocate and spread, in equal parts during the period of the actual term of this Agreement, all interest at any time contracted for, charged, received or reserved in connection with this Agreement. Section 9.14. Indemnification. The Borrower agrees to indemnify, defend and hold the Agent, the Co-Agent and each member of the Bank Group, their Affiliates and their officers, employees, agents, directors, shareholders and Affiliates (collectively, "Indemnified Persons") harmless from and against any and all loss, liability, damage, judgment, claim, deficiency or reasonable expense (including interest, penalties, reasonable attorneys' fees and amounts paid in settlement) incurred by or asserted against any Indemnified Person arising out of, in any way connected with, or as a result of (i) the execution and delivery of this Agreement and the other documents contemplated hereby, the performance by the parties hereto and thereto of its obligations hereunder and thereunder (including but not limited to the making of the Commitments of each Bank) and consummation of the transactions contemplated hereby and thereby, (ii) the actual or proposed use of the Letters of Credit or the proceeds of the Loans, (iii) any violation by the Borrower or any of its Subsidiaries of any Requirement of Law, including but not limited to Environmental Laws, (iv) ownership by the Bank Group of any real or personal property following foreclosure under the Security Documents, to the extent such losses, liabilities, damages, judgments, claims, deficiencies or expenses arise out of or result from the presence, disposal or release of any hazardous materials or solid waste in, on or under such property during the period owned, leased or operated by the Borrower or any of its Subsidiaries, including, without limitation, losses, liabilities, damages, judgments, claims, deficiencies or expenses which are imposed under Environmental Laws upon Persons by virtue of their ownership, (v) any member of the Bank Group being deemed an HOU04:43581.4 operator of any such real or personal property in circumstances in which no member of the Bank Group is generally operating or generally exercising control over such property, to the extent such losses, liabilities, damages, judgments, claims, deficiencies or expenses arise out of or result from any hazardous materials or solid waste located in, on or under such property or (vi) any claim, litigation, investigation or proceeding relating to any of the foregoing, whether or not any Indemnified Person is a party thereto; provided that such indemnity shall not apply to any such losses, claims, damages, liabilities or related expenses that are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or willful misconduct of such Indemnified Person. WITHOUT LIMITING ANY PROVISION OF THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS, IT IS THE EXPRESS INTENTION OF THE BORROWER THAT EACH INDEMNIFIED PERSON SHALL BE INDEMNIFIED AND HELD HARMLESS AGAINST ANY AND ALL LOSSES, LIABILITIES, CLAIMS, DEFICIENCIES, JUDGMENTS OR REASONABLE EXPENSES ARISING OUT OF OR RESULTING FROM THE ORDINARY NEGLIGENCE (WHETHER SOLE OR CONTRIBUTORY) OF SUCH INDEMNIFIED PERSON. THE OBLIGATIONS OF THE BORROWER UNDER THIS SECTION 9.14 SHALL SURVIVE THE TERMINATION OF THIS AGREEMENT. Section 9.15. Ratification of Security Documents. The Borrower hereby ratifies, adopts and confirms the Liens granted by and under the Security Documents as security for all of the Obligations. The Borrower further acknowledges and agrees that the term "Secured Obligations" as defined in the Security Agreement shall include, without limitation, the payment and performance of the Obligations as defined in this Agreement. Section 9.16. Confidentiality. In the event that the Borrower provides to the Agent or the Banks written confidential information belonging to the Borrower, if the Borrower shall denominate such information in writing as "confidential", the Agent and the Banks shall thereafter maintain such information in confidence in accordance with the standards of care and diligence that each utilizes in maintaining its own confidential information. This obligation of confidence shall not apply to such portions of the information which (i) are in the public domain, (ii) hereafter become part of the public domain without the Agent or the Banks breaching their obligation of confidence to the Borrower, (iii) are previously known by the Agent or the Banks from some source other than the Borrower, (iv) are hereafter obtained by or available to the Agent or the Banks from a third party who owes no obligation of confidence to the Borrower with respect to such information or through any other means other than through disclosure by the Borrower, (vi) are disclosed with the Borrower's consent, (vii) must be disclosed either pursuant to any Requirements of Law or to Persons regulating the activities of the Agent or the Banks, or (viii) as may be required by law or regulation or order of any Governmental Authority in any judicial, arbitration or governmental proceeding. Further, the Agent or a Bank may disclose any such information to any other Bank, any independent petroleum engineers or consultants, any independent certified public HOU04:43581.4 accountants, any legal counsel employed by such Person in connection with this Agreement or any Security Document, including without limitation, the enforcement or exercise of all rights and remedies thereunder, or any assignee or participant (including prospective assignees and participants) in the Loans; provided, however, that the Agent or Bank imposes on the Person to whom such information is disclosed the same obligation to maintain the confidentiality of such information as is imposed upon it hereunder. Notwithstanding anything to the contrary provided herein, this obligation of confidence shall cease three (3) years from the date the information was furnished, unless the Borrower requests in writing at least thirty (30) days prior to the expiration of such three year period, to maintain the confidentiality of such information for an additional three year period. The Borrower waives any and all other rights it may have to confidentiality as against the Agent and the Banks arising by contract, agreement, statute or law except as expressly stated in this Section 9.16.
