For so long as the Torch Agreements (or any similar agreement) are in effect, Torch and its Subsidiaries shall also be deemed Affiliates of the Related Persons.

ARTICLE II - The Loans Section 2.1. Advances. Subject to the terms and conditions hereof, each Lender agrees to make advances to Borrower (herein called such Lender's "Advances") upon request from time to time during the Commitment Period so long as (a) each Advance by such Lender does not exceed such Lender's Percentage Share of the aggregate amount of Advances then requested from all Lenders, and (b) the aggregate amount of such Lender's Advances outstanding at any time does not exceed such Lender's Percentage Share of the Available Borrowing Base determined as of the date on which the requested Advance is to be made. The aggregate amount of all Advances 26 requested of all Lenders in any Request for Advances must be greater than or equal to $3,000,000 or must equal the unadvanced portion of the Available Borrowing Base. The obligation of Borrower to repay to each Lender the aggregate amount of all Advances made by such Lender (herein called such Lender's "Loan"), together with interest accruing in connection therewith, shall be evidenced by a single promissory note (herein called such Lender's "Note") made by Borrower payable to the order of such Lender in the form of Exhibit A with appropriate insertions. The amount of principal owing on any Lender's Note at any given time shall be the aggregate amount of all Advances theretofore made by such Lender minus all payments of principal theretofore received by such Lender on such Note. Interest on each Note shall accrue and be due and payable as provided herein and therein. Subject to the terms and conditions hereof, Borrower may borrow, repay, and reborrow hereunder. Section 2.2. Requests for Advances. Borrower must give to Administrative Agent written notice, or telephonic notice promptly confirmed in writing, of any requested Advances, which notice must be received by Administrative Agent not later than 10:00 a.m., Dallas, Texas time, on the date of the requested Advances (or three Business Days prior to the date of the requested Advances if Borrower is desires for all or any part of such Advances to make up a Tranche of Fixed Rate Portions on such date). After receiving any such notice Administrative Agent shall give each Lender prompt notice of the requested Advances. Each such written request or confirmation must be made in the form and substance of the "Request for Advances" attached hereto as Exhibit B, duly completed. Each such telephonic request shall be deemed a representation, warranty, acknowledgment and agreement by Borrower as to the matters which are required to be set out in such written confirmation. If all conditions precedent to such Advances have been met, each Lender will on the date requested promptly remit to Administrative Agent at Administrative Agent's office in Dallas, Texas the amount of such Lender's Advance in immediately available funds, and upon receipt of such funds, unless to its actual knowledge any conditions precedent to such Advances have been neither met nor waived as provided herein, Administrative Agent shall promptly make the Advances available to Borrower. Each Request for Advances shall be irrevocable and binding on Borrower. Unless Administrative Agent shall have received prompt notice from a Lender that such Lender will not make available to Administrative Agent such Lender's Advance, Administrative Agent may in its discretion assume that such Lender has made such Advance available to Administrative Agent in accordance with this section and Administrative Agent may if it chooses, in reliance upon such assumption, make such Advance available to Borrower. If and to the extent such Lender shall not so make its Advance available to Administrative Agent, such Lender and Borrower severally agree to pay or repay to Administrative Agent within three days after demand the amount of such Advance together with interest thereon, for each day from the date such amount is made available to Borrower until the date such amount is paid or repaid to Administrative Agent, at (i) the Federal Funds Rate, in the case of such Lender, or (ii) the interest rate applicable at the time to the other Advances made on such date, in the case of Borrower. The failure of any Lender to make any Advance to be made by it hereunder shall not relieve any other Lender of its obligation hereunder, if any, to make its Advance, but neither Administrative Agent, Documentation Agent, nor any other Lender shall be responsible for the failure of such Lender to make any Advance to be made by such Lender. 27 Section 2.3. Use of Proceeds. Borrower shall use all funds from Advances for general corporate purposes. In no event shall the funds from any Advance be used directly or indirectly by any Person for personal, family, household or agricultural purposes. Borrower represents and warrants to Lender that Borrower is not engaged principally, or as one of Borrower's important activities, in the business of extending credit to others for the purpose of purchasing or carrying any "margin stock" (as such term is defined in Regulation U promulgated by the Board of Governors of the Federal Reserve System). Section 2.4. Rate Elections. Borrower may from time to time designate all or any portions of the Loans (including any yet to be made Advances which are to be made prior to or at the beginning of the designated Interest Period but excluding any portions of the Loans which are required to be repaid prior to the end of the designated Interest Period) as a "Tranche", which term refers to a set of Fixed Rate Portions with identical Interest Periods and with each Lender participating in such Tranche in accordance with its Percentage Share. Without the consent of Majority Lenders, Borrower may make no such election during the continuance of a Default under Section 5.2 or of an Event of Default, and Borrower may make such an election with respect to already existing Fixed Rate Portions only if such election will take effect at or after the termination of the Interest Period applicable thereto. Each election by Borrower of a Tranche shall: (a) Be made in writing in the form and substance of the "Rate Election" attached hereto as Exhibit C, duly completed; (b) Specify the aggregate amount of the Loans which Borrower desires to designate as such Tranche, the first day of the Interest Period which is to apply thereto, and the length of such Interest Period; and (c) Be received by Administrative Agent not later than 10:00 a.m., Dallas, Texas time, on the third Business Day preceding the first day of the specified Interest Period. Promptly after receiving any such election (herein called a "Rate Election") which meets the requirements of this section, Administrative Agent shall notify each Lender thereof. Each Rate Election shall be irrevocable. Borrower may make no Rate Election which does not specify an Interest Period complying with the definition of "Interest Period" in Section 1.1, and the aggregate amount of the Tranche elected in any Rate Election must be $3,000,000 or more. Upon the termination of each Interest Period the portion of each Loan within the related Tranche shall, unless the subject of a new Rate Election then taking effect, automatically become a part of the Base Rate Portion of such Loan and become subject to all provisions of the Loan Documents governing such Base Rate Portion. Borrower shall have no more than five Tranches in effect at any time. Section 2.5. Facility Fees. In consideration of each Lender's commitment to make Advances, Borrower will pay to Administrative Agent for the account of each Lender a facility fee, determined on a daily basis, equal to (a) the per annum percentage set forth in the first column of the following table opposite the range set forth in the second column of such table in 28 which range is included the Borrowing Base Utilization, times (b) the Maximum Loan Amount from time to time in effect: Per Annum Rate Borrowing Base Utilization 0.25% less than 25% 0.375% 25% or more but less than 75% 0.5% 75% or more provided that, if such Maximum Loan Amount exceeds the Borrowing Base in effect at the same time, the facility fee for such excess shall be reduced to one- eighth of one percent (0.125%) per annum and provided further that, upon any increase in the Borrowing Base, Borrower shall pay an additional facility fee equal to any unpaid facility fee which would have been due (at the applicable full prorated rate of 0.25%, 0.375% or 0.5% per annum, as the case may be) had such increased Borrowing Base been in effect for the one year period preceding the date of such increase (or, if less, for the period from the beginning of the Commitment Period to the date of such increase). These facility fees shall be due and payable in arrears on the last day of each Fiscal Quarter and at the end of the Commitment Period. Section 2.6. Administrative Agent's Fees. In addition to all other amounts due to Administrative Agent under the Loan Documents, Borrower will pay certain fees to Administrative Agent in accordance with the Fee Letter or as otherwise from time to time hereafter agreed by Administrative Agent and Borrower. Section 2.7. Optional Prepayments. Borrower may from time to time and without premium or penalty make optional prepayments of the Notes, in whole or in part, so long as the aggregate amounts of all partial prepayments of principal on the Notes equals $3,000,000 or more and Borrower concurrently pays all amounts then due under Section 2.16. Borrower shall give notice of any such prepayment to Administrative Agent not later than 10:00 a.m., Dallas, Texas time, on the date of such prepayment, provided that such notice must be given at least three Business Days prior to such date if all or any part of Fixed Rate Portions are to be prepaid. Each prepayment of principal under this section shall be accompanied by all interest then accrued and unpaid on the principal so prepaid (provided that Borrower may, if it wishes, defer payment of any such interest on Base Rate Portions of Loans until the next "Base Rate Payment Date" specified in the Notes). Any principal or interest prepaid pursuant to this section shall be in addition to, and not in lieu of, all payments otherwise required to be paid under the Loan Documents at the time of such prepayment. Section 2.8. Mandatory Prepayments. (a) If at any time the aggregate unpaid principal balance of the Loans exceeds the Maximum Loan Amount (whether due to a reduction in the Maximum Loan Amount in accordance with this Agreement, or otherwise), Borrower shall immediately upon demand prepay the principal of the Loans in an amount at least equal to such excess. 29 (b) If at any time the aggregate unpaid principal balance of the Loans is less than the Maximum Loan Amount but in excess of the Available Borrowing Base (such excess being herein called a "Borrowing Base Deficiency") Borrower shall, within five Business Days after Administrative Agent gives notice of such fact to Borrower, either: (i) prepay the principal of the Loans or (subject to Section 5.2(c)) the principal of Additional Senior Indebtedness in an aggregate amount at least equal to such Borrowing Base Deficiency, or (ii) give notice to Administrative Agent electing to prepay the principal of the Loans in up to six (or, at the option of Majority Lenders, up to twelve) monthly installments in an aggregate amount at least equal to such Borrowing Base Deficiency, with each such installment equal to or in excess of the percentage of such Borrowing Base Deficiency equal to one divided by the number of such scheduled installments, and with the first such installment to be paid one month after the giving of such notice and the subsequent installments to be due and payable at one month intervals thereafter until such Borrowing Base Deficiency has been eliminated, or (iii) give notice to Administrative Agent that Borrower desires to provide Administrative Agent with deeds of trust, mortgages, chattel mortgages, security agreements, financing statements and other security documents in form and substance satisfactory to Administrative Agent, granting, confirming, and perfecting first and prior liens or security interests in Oil and Gas Properties or other collateral acceptable to Majority Lenders, to the extent needed to allow Majority Lenders to increase the Borrowing Base (as they in their reasonable discretion deem consistent with prudent oil and gas banking industry lending standards at the time) to an amount which eliminates such Borrowing Base Deficiency, and then provide such security documents within thirty days after Administrative Agent specifies such Oil and Gas Properties or other collateral to Borrower. (If, prior to any such specification by Administrative Agent, Majority Lenders determine that the giving of such security documents will not serve to eliminate such Borrowing Base Deficiency, then, within five Business Days after receiving notice of such determination, Borrower will elect to make, and thereafter make, the prepayments specified in either of the preceding subsections (i) or (ii) of this subsection (b).) (c) For so long as any Borrowing Base Deficiency has occurred and is continuing, Borrower will keep account of all asset sales and other transactions thereafter made by the Related Persons which are permitted under Section 5.2(f)(iii). At each time when the aggregate proceeds from such transactions (net of transaction costs and taxes) equals or exceeds $3,000,000, Borrower will, if such Borrowing Base Deficiency still exists, prepay the Loans in an amount equal to such aggregate net proceeds. Such prepayments shall be applied to any installments due under the preceding subsection (b)(ii) as directed by Borrower. (d) Each prepayment of principal under this section shall be accompanied by all interest then accrued and unpaid on the principal so prepaid. Any principal or interest prepaid pursuant to this section shall be in addition to, and not in lieu of, all payments otherwise required to be paid under the Loan Documents at the time of such prepayment. 30 Section 2.9. Payments to Lenders. Borrower will make each payment which it owes under the Loan Documents to Administrative Agent for the account of Administrative Agent or the Lender to whom such payment is owed. Each such payment must be received by Administrative Agent not later than 11:00 a.m., Dallas, Texas time, on the date such payment becomes due and payable, in lawful money of the United States of America, without set-off, deduction or counterclaim, and in immediately available funds. Any payment received by Administrative Agent after such time will be deemed to have been made on the next following Business Day. Should any such payment become due and payable on a day other than a Business Day, the maturity of such payment shall be extended to the next succeeding Business Day, and, in the case of a payment of principal or past due interest, interest shall accrue and be payable thereon for the period of such extension as provided in the Loan Document under which such payment is due. Each payment under a Loan Document shall be due and payable at the place provided therein and, if no specific place of payment is provided, shall be due and payable at the place of payment of Administrative Agent's Note. When Administrative Agent collects or receives money on account of the Obligations or otherwise pursuant to the Security Documents, Administrative Agent shall distribute all money so collected or received, and Lenders and Administrative Agent shall apply all such money so distributed, as follows: (a) first, for the payment of all Obligations which are then due (and if such money is insufficient to pay all such Obligations, first to any reimbursements due Administrative Agent under Section 5.1(i) or (j) and then to the partial payment of all other Obligations then due in proportion to the amounts thereof, or as Supermajority Lenders shall otherwise agree); (b) then for the prepayment of amounts owing under the Loan Documents (other than principal on the Notes) if so specified by Borrower; (c) then for the prepayment of principal on the Notes, together with accrued and unpaid interest on the principal so prepaid; and (d) then, for the payment or prepayment of any other Obligations; and (e) then, to the extent such money received is pursuant to the exercise of remedies under the Security Documents only, for the pro rata payment of any other indebtedness or obligations to Lenders secured by the Security Documents, including without limitation any indebtedness or obligations under any Derivative Contracts between any Related Person and any Lender; and (f) the remainder, if any, to Borrower. All payments applied to principal or interest on any Note shall be applied first to any interest then due and payable, then to principal then due and payable, and last to any prepayment of principal and interest in compliance with Sections 2.7 and 2.8. All distributions of amounts described in any of subsections (b), (c) or (d) above shall be made by Administrative Agent pro rata to Administrative Agent and each Lender then owed Obligations described in such subsection in 31 proportion to all amounts owed to Administrative Agent and all Lenders which are described in such subsection. Section 2.10. Initial Borrowing Base. During the period from the date hereof to the first Determination Date the Borrowing Base shall be $200,000,000. Section 2.11. Subsequent Determinations of Borrowing Base. (a) By each Evaluation Date, Borrower shall furnish to each Lender the Engineering Report described in Section 5.1(b)(iv), together with all other information and data which Administrative Agent has then reasonably requested concerning the Related Persons' businesses and properties. Within thirty days after receiving such reports and other information and data, or as promptly thereafter as practicable, Administrative Agent shall propose to Lenders an amount for the Borrowing Base, and within thirty days thereafter each Lender will notify Administrative Agent of whether or not it accepts such proposed amount. Failure of any Lender to give such notice within such time period shall be deemed to constitute acceptance of such proposed amount by such Lender. If such proposed amount is not accepted by Majority Lenders (or, if Administrative Agent has proposed an increase in the Borrowing Base, by Supermajority Lenders), Administrative Agent and Lenders shall continue to discuss a new Borrowing Base until such time as Administrative Agent and Majority Lenders (or, if the Borrowing Base is to be increased, Supermajority Lenders) shall have agreed upon an amount for the new Borrowing Base, and promptly thereafter Administrative Agent shall notify Borrower of such amount. (b) Within five Business Days after receipt of such notice from Administrative Agent, Borrower shall by notice to Administrative Agent either accept such amount as the new Borrowing Base or reduce the Borrowing Base from the amount proposed by Administrative Agent to any lesser amount. (Failure by Borrower to take either such action within such five Business Day period shall be deemed acceptance of such amount.) Upon any such acceptance or deemed acceptance by Borrower, a new Borrowing Base in the amount accepted shall take effect on such date (herein called a "Determination Date") and shall remain in effect until but not including the next Determination Date. Upon any such reduction by Borrower, a new Borrowing Base in the reduced amount specified by Borrower shall take effect on such date (herein also called a "Determination Date") and shall remain in effect until but not including the next Determination Date. (c) Whenever any of the following events occur: (i) the Related Persons, in one or more transactions after the Determination Date immediately preceding the time in question (or, prior to the first Determination Date, after the date hereof) make aggregate Borrowing Base Asset Sales of $50,000,000 or more, or (ii) Borrower decides, as contemplated in Section 5.2(b)(iv), to make any unscheduled payment of Subordinated Indebtedness, or (iii) the Related Persons, in one or more transactions after the Determination Date immediately preceding the time in question (or, prior to the first Determination Date, after 32 the date hereof) make aggregate Forward Sales/Production Payments of $10,000,000 or more, then Borrower will promptly give notice of such event to Administrative Agent and each Lender and, upon receipt of such notice, Majority Lenders (acting through Administrative Agent) may, at their option, either (1) specify an additional Evaluation Date as contemplated in subsection (d) of the definition in Section 1.1 of "Evaluation Date" and thereafter receive the reports and information, and make the determinations, contemplated above in this Section 2.11, or (2) request any supplemental information which they reasonably desire from Borrower without requiring all such reports and other information, and then designate a new Borrowing Base as they deem appropriate in light of such event and such supplemental information (provided that any increase in the Borrowing Base must be consented to by Supermajority Lenders). Upon any such designation, a new Borrowing Base in the amount designated shall take effect on such date (herein also called a "Determination Date") and shall remain in effect until but not including the next Determination Date. (d) If Borrower does not furnish all of the reports, information, and data referred to in the first sentence of subsection (a) of this section by the date specified in such sentence, or promptly furnish any supplemental information which Administrative Agent requests as contemplated in clause (2) of subsection (c) of this section, then Administrative Agent may designate the Borrowing Base at any amount which Administrative Agent and Majority Lenders (or Supermajority Lenders, in the case of an increase) determine and may redesignate the Borrowing Base from time to time thereafter until each Lender receives all such information, reports and data, whereupon Administrative Agent and Lenders shall determine, and Borrower shall accept or reduce, a new Borrowing Base as described in subsections (a), (b) and (c) of this section. Section 2.12. Prudent Industry Lending Standards. Administrative Agent and Majority Lenders (or Supermajority Lenders) shall determine the amount of the Borrowing Base based upon the loan value which they in their reasonable discretion assign to the various Borrowing Base Assets of the Related Persons at the time in question and based upon such other credit factors as they in their reasonable discretion deem consistent with prudent oil and gas banking industry lending standards at the time (such as general market conditions, pricing forecasts, and the assets, liabilities, cash flow, hedged and unhedged exposures to product price and interest rate changes, business, properties, management and ownership of Borrower and its Affiliates). It is expressly understood that Lenders and Administrative Agent have no obligation to agree upon or designate the Borrowing Base at any particular amount, whether in relation to the Maximum Loan Amount or otherwise, and that Lenders' commitments to advance funds hereunder are determined by reference to the Available Borrowing Base as from time to time in effect. Section 2.13. Capital Reimbursement. If at any time after the date hereof, and from time to time, any Lender determines that the adoption or modification of any applicable law, rule or regulation regarding such Lender's required levels of reserves, deposits, insurance or capital (including any allocation of capital requirements or conditions), or similar requirements, or any interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation, administration or compliance of such Lender with any of such requirements, has or would have the effect of (a) increasing such Lender's costs 33 relating to the Obligations owing to such Lender, or (b) reducing the yield or rate of return of such Lender on such Obligations, to a level below that which such Lender could have achieved but for the adoption or modification of any such requirements, Borrower shall, within 30 days after any request sent by such Lender to Borrower (with a copy to Administrative Agent), pay to Administrative Agent for the account of such Lender such additional amounts as (in such Lender's reasonable judgment, after reasonable computation) will compensate such Lender for such increase in costs or reduction in yield or rate of return of such Lender. Subject to Section 2.18(b), no failure by such Lender to immediately demand payment of any additional amounts payable under this section shall constitute a waiver of such Lender's right to demand payment of such amounts at any subsequent time. Nothing herein contained shall be construed or so operate as to require Borrower to pay any interest, fees, costs or charges not permitted by Section 9.6. Section 2.14. Increased Cost of Fixed Rate Portions. If the introduction of or any change in any applicable domestic or foreign law, treaty, rule or regulation (whether now in effect or hereinafter enacted or promulgated, including Regulation D) or any interpretation or administration thereof by any governmental authority charged with the interpretation or administration thereof (whether or not having the force of law): (a) shall change the basis of taxation of payments to any Lender of any principal, interest, or other amounts attributable to any Fixed Rate Portion or otherwise due under this Agreement in respect of any Fixed Rate Portion (other than franchise taxes or income taxes imposed on the overall net income, assets, net worth or shareholders' capital of such Lender or of any lending office of such Lender by any jurisdiction in which such Lender's principal office or any such lending office is located); or (b) shall change, impose, modify, apply or deem applicable any Reserve Requirement or other reserve, special deposit or similar requirement in respect of any Fixed Rate Portion of any Lender or against assets of, deposits with or for the account of, or credit extended by, such Lender; or (c) shall impose on any Lender or the interbank eurocurrency deposit market any other condition affecting any Fixed Rate Portion, the result of which is to increase the cost to any Lender of funding or maintaining any Fixed Rate Portion or to reduce the amount of any sum receivable by any Lender in respect of any Fixed Rate Portion by an amount deemed by such Lender to be material, then such Lender shall promptly notify Administrative Agent and Borrower in writing of the happening of such event and of the amount required to compensate such Lender for such event, whereupon (i) Borrower shall pay such amount to Administrative Agent for the account of such Lender and (ii) Borrower may elect, by giving to Administrative Agent and Lender not less than three Business Days' notice, to convert all (but not less than all) of any such Fixed Rate Portion into a part of the Base Rate Portion. Section 2.15. Availability. If (a) any change in applicable laws, treaties, rules or regulations or in the interpretation or administration thereof of or in any jurisdiction whatsoever, 34 domestic or foreign, shall make it unlawful or impracticable for any Lender to fund or maintain Fixed Rate Portions, or shall materially restrict the authority of any Lender to purchase or take offshore deposits of dollars (i.e., "eurodollars"), or (b) any Lender determines that matching deposits appropriate to fund or maintain any Fixed Rate Portion are not available to it, or (c) any Lender determines that the formula for calculating the Adjusted Eurodollar Rate does not fairly reflect the cost to such Lender of making or maintaining loans based on such rate, then, upon notice by such Lender to Borrower and Administrative Agent, Borrower's right to elect Fixed Rate Portions of such Lender's Loan shall be suspended to the extent and for the duration of such illegality, impracticability or restriction and all Fixed Rate Portions of such Lender's Loan (or portions thereof) which are then outstanding or are then the subject of any Rate Election and which cannot lawfully or practicably be maintained or funded shall immediately become or remain part of the Base Rate Portion of such Lender's Loan. Borrower agrees to indemnify Administrative Agent and each Lender and hold it harmless against all costs, expenses, claims, penalties, liabilities and damages which may result from any such change in law, treaty, rule, regulation, interpretation or administration. Section 2.16. Funding Losses. In addition to its other obligations hereunder, Borrower will indemnify Administrative Agent and each Lender against, and reimburse Administrative Agent and each Lender on demand for, any loss or expense incurred or sustained by Administrative Agent or such Lender (including any loss or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by a Lender to fund or maintain Fixed Rate Portions or Advances), as a result of any payment or prepayment (whether authorized or required hereunder or otherwise) of all or a portion of a Fixed Rate Portion on a day other than the day on which the applicable Interest Period ends, any payment or prepayment, whether required hereunder or otherwise, of a Loan made after the delivery, but before the effective date, of a Rate Election, if such payment or prepayment prevents such Rate Election from becoming fully effective, the failure of any Advance to be made or of any Rate Election to become effective due to any condition precedent not being satisfied or due to any other action or inaction of any Related Person, or any conversion (whether authorized or required hereunder or otherwise) of all or any portion of any Fixed Rate Portion into a Base Rate Portion or into a different Fixed Rate Portion on a day other than the day on which the applicable Interest Period ends. Section 2.17. Reimbursable Taxes. Borrower covenants and agrees that: (a) Borrower will indemnify Administrative Agent and each Lender against and reimburse Administrative Agent and each Lender for all present and future income, stamp and other taxes, levies, costs and charges whatsoever imposed, assessed, levied or collected on or in respect of this Agreement or any Fixed Rate Portions (whether or not legally or correctly imposed, assessed, levied or collected), excluding, however, any franchise taxes or income taxes imposed on or measured by the overall net income, assets, net worth or shareholders' capital of Administrative Agent or such Lender or any lending office of Administrative Agent or such Lender by any jurisdiction in which Administrative Agent or such Lender or any such lending office is located (all such non-excluded taxes, levies, costs and charges being collectively called "Reimbursable 35 Taxes" in this section). Such indemnification shall be on an after-tax basis, taking into account any taxes imposed on the amounts paid as indemnity. (b) All payments on account of the principal of, and interest on, each Lender's Loan and each Lender's Note, and all other amounts payable by Borrower to Administrative Agent and each Lender hereunder, shall be made in full without set-off or counterclaim and shall be made free and clear of and without deductions or withholdings of any nature by reason of any Reimbursable Taxes, all of which will be for the account of Borrower. In the event of Borrower being compelled by law or other regulations to make any such deduction or withholding from any payment to Administrative Agent or any Lender, Borrower shall pay on the due date of such payment, by way of additional interest, such additional amounts as are needed to cause the amount receivable by Administrative Agent or such Lender after such deduction or withholding to equal the amount which would have been receivable in the absence of such deduction or withholding. If Borrower should make any deduction or withholding as aforesaid, Borrower shall within 60 days thereafter forward to Administrative Agent or such Lender an official receipt or other official document evidencing payment of such deduction or withholding. (c) If Borrower is ever required to pay any Reimbursable Tax with respect to any Fixed Rate Portion, Borrower may elect, by giving to Administrative Agent and each Lender not less than three Business Days' notice, to convert all (but not less than all) of any such Fixed Rate Portion into a part of the Base Rate Portion, but such election shall not diminish Borrower's obligation to pay all Reimbursable Taxes. (d) Notwithstanding the foregoing provisions of this section, Borrower shall be entitled, to the extent it is required to do so by law, to deduct or withhold (and not to make any indemnification or reimbursement for) income or other similar taxes imposed by the United States of America (other than any portion thereof attributable to a change in federal income tax laws effected after the date hereof) from interest, fees or other amounts payable hereunder for the account of any Lender, other than a Lender (i) who is a U.S. person for Federal income tax purposes or (ii) who has the Prescribed Forms on file with Administrative Agent (with copies provided to Borrower) for the applicable year to the extent deduction or withholding of such taxes is not required as a result of the filing of such Prescribed Forms, provided that if Borrower shall so deduct or withhold any such taxes, it shall provide a statement to Administrative Agent and such Lender, setting forth the amount of such taxes so deducted or withheld, the applicable rate and any other information or documentation which such Lender may reasonably request for assisting such Lender to obtain any allowable credits or deductions for the taxes so deducted or withheld in the jurisdiction or jurisdictions in which such Lender is subject to tax. As used in this section, "Prescribed Forms" means such duly executed forms or statements, and in such number of copies, which may, from time to time, be prescribed by law and which, pursuant to applicable provisions of (x) an income tax treaty between the United States and the country of residence of the Lender providing the forms or statements, (y) the Internal Revenue Code of 1986, as amended from time to time, or (z) any applicable 36 rules or regulations thereunder, permit Borrower to make payments hereunder for the account of such Lender free of such deduction or withholding of income or similar taxes. Section 2.18. Change of Lending Office and Lender; Time Limit; etc. (a) Each Lender agrees that, upon the occurrence of any event giving rise to the operation of Sections 2.13 through 2.17 with respect to such Lender, it will, if requested by Borrower, use reasonable efforts (subject to overall policy considerations of such Lender) to designate another lending office for its Loan (provided that such designation is made on such terms that such Lender and its lending office suffer no economic, legal or regulatory disadvantage) with the object of avoiding the consequence of the event giving rise to the operation of any such section. Nothing in this subsection shall affect or postpone any of the obligations of Borrower or the right of any Lender provided in Sections 2.13 through 2.17. (b) If any Lender elects to pass through to Borrower any charge or cost under Sections 2.13 through 2.17 or elects to terminate the availability of Fixed Rate Portions for any period of time, Borrower may elect to terminate such Lender as a party to this Agreement; provided that, prior to or concurrently with such termination, Borrower must either (i) if Administrative Agent and each non-terminated Lender consent, pay to the terminated Lender all principal, interest, fees, costs and other Obligations owed to such Lender and accrued through the date of termination and terminate such Lender's commitment to make Advances hereunder, in which event the Maximum Loan Amount shall be reduced by the Percentage Share thereof of the terminated Lender, or (ii) arrange for one or more Eligible Transferees to purchase the rights and duties of the terminated Lender pursuant to Section 9.4(c), in which event the terminated Lender will assign all of such rights and duties to such Eligible Transferees. Prior to arranging for any Person other than an existing Lender to be such an Eligible Transferee, Borrower shall notify the other Lenders of its intention to replace the terminated Lender and, during the sixty day period after such notice, the other Lenders shall have a right of first refusal to purchase the rights and duties of the terminated Lender, pro rata in accordance with their Percentage Shares. (c) Notwithstanding anything to the contrary in Sections 2.13 through 2.17, Borrower shall not be required to reimburse or pay any costs or expenses to any Lender as required under such sections which have accrued more than ninety (90) days prior to such Lender's giving notice to Borrower that such Lender has suffered or incurred such costs or expenses.

ARTICLE IV - Representations and Warranties Section 4.1. Borrower's Representations and Warranties. To confirm each Lender's understanding concerning Borrower and Borrower's business, properties and obligations and to induce Administrative Agent and each Lender to enter into this Agreement and to make the Loans, Borrower and each other Related Person which is a party hereto represents and warrants to Administrative Agent and each Lender that: (a) No Default. No Related Person is in default in the performance of any of the covenants and agreements contained herein. No event has occurred and is continuing which constitutes a Default. (b) Organization and Good Standing. Each Related Person which is a corporation or partnership is duly organized, validly existing and in good standing under the laws of its state of organization, having all corporate or partnership powers required to carry on its business and enter into and carry out the transactions contemplated hereby. Each such Related Person is duly qualified, in good standing, and authorized to do business in all other jurisdictions within the United States wherein the character of the properties owned or held by it or the nature of the business transacted by it makes such qualification necessary, except where the failure to so qualify, be in good standing, or be authorized to do business has no material probability of having a Material Adverse Effect. Each such Related Person has taken all actions and procedures customarily taken in order to enter, for the purpose of conducting business or owning property, each jurisdiction outside the United States wherein the character of the properties owned or held by it or the nature of the business transacted by it makes such actions and procedures prudent, except where the failure to do so has no material probability of having a Material Adverse Effect. 39 (c) Authorization. Each Related Person which is a corporation or partnership has duly taken all corporate or partnership action necessary to authorize the execution and delivery by it of the Loan Documents to which it is a party and to authorize the consummation of the transactions contemplated thereby and the performance of its obligations thereunder. Borrower is duly authorized to borrow funds hereunder. (d) No Conflicts or Consents. The execution and delivery by the various Related Persons of the Loan Documents to which each is a party, the performance by each of its obligations under such Loan Documents, and the consummation of the transactions contemplated by the various Loan Documents, do not and will not: (i) conflict with the articles or certificate of incorporation, bylaws, charter, or partnership agreement or certificate of any Related Person, (ii) conflict with any provision of any domestic or foreign law, statute, rule or regulation, or with any agreement, judgment, license, order or permit applicable to or binding upon any Related Person or any Unrestricted Subsidiary, (iii) result in the acceleration of any Liability owed by any Related Person, or (iv) result in or require the creation of any Lien upon any assets or properties of any Related Person in any way which causes a Default to occur hereunder, which has a material probability of having a Material Adverse Effect, or which adversely affects the enforceability of the Loan Documents. No consent, approval, authorization or order of, and no notice to or filing with, any court or governmental authority or third party (other than recording of Security Documents with appropriate governmental authorities) is required in connection with the execution, delivery or performance by any Related Person of any Loan Document to which it is a party or to consummate any transactions contemplated by the Loan Documents, except for those which, if not obtained, do not cause any Default to occur hereunder, do not cause any Material Adverse Effect, and do not adversely affect the enforceability of the Loan Documents. The Obligations evidenced by the Notes constitute "Senior Indebtedness" of the Company as defined in the TECON Debentures, "Specified Senior Indebtedness" as defined in the 1996 Indenture, and equivalent "Senior Indebtedness" (regardless of how named) with respect to any other Permitted Subordinated Trust Indebtedness and Permitted Preferred Trust Securities. The Obligations of the Subsidiary Guarantors, if any, with respect to the Notes constitute "Specified Guarantor Senior Indebtedness" as defined in the 1996 Indenture. All borrowings made under the Notes are and will be made in compliance with the restrictions contained in Section 10.12(a) of the 1996 Indenture. (e) Enforceable Obligations. This Agreement is, and the other Loan Documents when duly executed and delivered will be, legal, valid and binding obligations of each Related Person which is a party hereto or thereto, enforceable in accordance with their terms except as such enforcement may be limited by bankruptcy, insolvency or similar laws of general 40 application relating to the enforcement of creditors' rights or by the discretionary application by a court of general principles of equity. (f) Initial Financial Statements. The Initial Financial Statements fairly present the matters addressed therein. Since the date of the audited annual Initial Financial Statements no event or condition having a Material Adverse Effect has occurred, except as reflected in the Disclosure Schedule or a Disclosure Report. All Initial Financial Statements were prepared in accordance with GAAP. (g) Other Obligations and Restrictions. No Related Person has any outstanding Liabilities of any kind (including contingent obligations, tax assessments, and unusual forward or long-term commitments) which are, in the aggregate, material to Borrower or material with respect to the consolidated financial condition of Borrower and its Subsidiaries and not shown in the Initial Financial Statements or disclosed in the Disclosure Schedule or a Disclosure Report. Except as shown in the Initial Financial Statements or disclosed in the Disclosure Schedule or a Disclosure Report, no Related Person is subject to or restricted by any franchise, contract, deed, charter restriction, or other instrument or restriction which has a material probability of having a Material Adverse Effect.

There is no fact known to any Related Person (other than industry- wide risks normally associated with the types of businesses conducted by the Related Persons) that has not been disclosed to Administrative Agent and each Lender in writing which has a material probability of having a Material Adverse Effect. All data and information which the Related Persons have furnished to the Approved Petroleum Engineers or any Lender in connection with any Engineering Report is true, correct and complete in all material respects, and, to the best knowledge of Borrower, there are no statements or conclusions in any Engineering Report which are based upon or include misleading data and information or fail to take into account material data and information regarding the matters reported therein.

Borrower has heretofore delivered to Administrative Agent and each Lender true, correct and complete copies of the Initial Financial Statements and the Initial Engineering Report. (i) Litigation. Except as disclosed in the Initial Financial Statements or in the Disclosure Schedule or a Disclosure Report: (i) to the best knowledge of Borrower, there are no actions, suits or legal, equitable, arbitrative or administrative proceedings pending or threatened against any Related Person or Unrestricted Subsidiary before any federal, state, municipal or other court, department, commission, body, board, bureau, agency, or instrumentality, domestic or foreign, which have a material probability of having a Material Adverse Effect, and (ii) there are no outstanding judgments, injunctions, writs, rulings or orders by any such governmental entity against any Related Person, any Unrestricted Subsidiary, or any Related Person's stockholders, partners, directors or officers which have a material probability of having a Material Adverse Effect.

(m) Names and Places of Business. Neither Borrower nor any Subsidiary Guarantor has, during the preceding five years, had, been known by, or used any other corporate, partnership, trade, or fictitious name, except as disclosed in the Disclosure Schedule or a Disclosure Report. Except as otherwise indicated in the Disclosure Schedule or a Disclosure Report, the chief executive office and principal place of business of Borrower and each Subsidiary Guarantor is located at the address of Borrower set out in Section 9.3. (n) Borrower's Subsidiaries. All of Borrower's Subsidiaries are either Restricted Subsidiaries or Unrestricted Subsidiaries; as of the date hereof Borrower has no Material Restricted Subsidiaries. Borrower does not have any Unrestricted Subsidiary or any Restricted Subsidiary or own, directly or indirectly, any stock or other Equity Interest in any other Person except those listed in the Disclosure Schedule or a Disclosure Report. No Related Person is a member of any general or limited partnership, joint venture or association of any type whatsoever except (i) those listed in the Disclosure Schedule or a Disclosure Report and (ii) associations, joint ventures or other relationships (1) which are established pursuant to a standard form operating agreement or similar agreement or which are partnerships for purposes of income taxation only, (2) which are not corporations or partnerships (or subject to the Uniform Partnership Act) under applicable state law, and (3) whose businesses are limited to the exploration, development and operation of oil, gas or mineral properties and interests owned directly by the parties in such associations, joint ventures or relationships. Except as otherwise revealed in a Disclosure Report, Borrower owns, directly or indirectly, the Equity Interest in each of its Subsidiaries which is indicated in the Disclosure Schedule. 43 (o) Title to Properties; Licenses. Each Related Person has good and defensible title to (i) all Collateral and all material Borrowing Base Assets which it purports to possess, as of the time in question, and (ii) all of its other material properties and assets in the United States, free and clear in all cases of all Liens other than Permitted Liens and of all encumbrances which interfere in any material respect with the ordinary conduct of the business of the owner of the property or assets subject thereto, except that (1) no representation or warranty is made with respect to any oil, gas or mineral property or interest to which no proved oil or gas reserves are properly attributed and (2) Borrower may be required, in connection with the California Real Estate and other acquisitions, to obtain various post-closing consents to assignments and transfers which are normally obtained in the ordinary course of the oil and gas business following the acquisition of oil and gas properties. Each Related Person possesses all licenses, permits, franchises, patents, copyrights, trademarks and trade names, and other intellectual property (or otherwise possesses the right to use such intellectual property) which are reasonably necessary to carry out its business as presently conducted and as presently proposed to be conducted hereafter, and no Related Person is in violation of the terms under which it possesses such intellectual property or the right to use such intellectual property in any way which has a material probability of having a Material Adverse Effect. (p) Government Regulation. Neither Borrower nor any other Related Person owing Obligations is subject to regulation under the Public Utility Holding Company Act of 1935, the Federal Power Act, the Investment Company Act of 1940 (as any of the preceding acts have been amended) or any other statute, law, regulation or decree which restricts the incurring by such Person of any Obligations, including statutes, laws, regulations or decrees relating to common contract carriers or the sale of electricity, gas, steam, water or other public utility services. (q) Benefit to Guarantors. At such time as any Subsidiary Guarantor shall become a party hereto pursuant to Section 6.1, and so long thereafter as any Subsidiary Guarantor shall be a party hereto, Borrower, each Subsidiary Guarantor, and the other Restricted Subsidiaries are mutually dependent on each other in the conduct of their respective businesses under a holding company structure, with the credit needed from time to time by each often being provided by another or by means of financing obtained by one with the support of the others for their mutual benefit, and the ability of each to obtain such financing is dependent on the successful operations of the others. The board of directors of each Subsidiary Guarantor has determined that such Subsidiary Guarantor's execution, delivery and performance of this Agreement may reasonably be expected to directly or indirectly benefit such Subsidiary Guarantor and are in the best interests of such Subsidiary Guarantor. (r) Reasonable Consideration for Guaranties. At such time as any Subsidiary Guarantor shall become a party hereto pursuant to Section 6.1, and so long thereafter as any Subsidiary Guarantor shall be a party hereto, the direct or indirect value of the consideration received and to be received by each Subsidiary Guarantor in connection herewith is reasonably worth at least as much as the liability and obligations of such Subsidiary Guarantor hereunder, and the incurrence of such liability and obligations in return for such consideration may reasonably be expected to benefit such Subsidiary Guarantor, directly or indirectly. 44 (s) No Insolvencies. Neither Borrower nor any Subsidiary Guarantor is "insolvent" on the date hereof (that is, the sum of such Person's absolute and contingent liabilities, including the Obligations, does not exceed the fair market value of such Person's assets, including any rights of contribution, reimbursement or indemnity). Each of Borrower and the Subsidiary Guarantors has capital which is adequate for the businesses in which such Person is engaged and intends to be engaged. Neither Borrower nor any Subsidiary Guarantor has incurred (whether hereby or otherwise), nor does Borrower or any Subsidiary Guarantor intend to incur or believe that it will incur, Liabilities which will be beyond its ability to pay as such Liabilities mature. Section 4.2. Representation by Lenders. Each Lender hereby represents that it will acquire its Note for its own account in the ordinary course of its commercial lending business; however, the disposition of such Lender's property shall at all times be and remain within its control and, in particular and without limitation, such Lender may sell or otherwise transfer its Note, any participation interest or other interest in its Note, or any of its other rights and obligations under the Loan Documents as set forth in Section 9.4. ARTICLE V - Covenants of Borrower Section 5.1. Affirmative Covenants.

These financial statements shall contain a consolidated and consolidating balance sheet as of the end of such Fiscal Year, consolidated and consolidating statements of operations for such Fiscal Year, and consolidated statements 45 of cash flows and of changes in stockholders' equity for such Fiscal Year, each setting forth in comparative form the corresponding figures for the preceding Fiscal Year. In addition, within ninety days after the end of each Fiscal Year Borrower will furnish a report signed by such accountants stating that they have read this Agreement and that in making the examination and reporting on the consolidated financial statements described above they did not conclude that any Default existed at the end of such Fiscal Year or at the time of their report, or, if they did conclude that a Default existed, specifying its nature and period of existence. (ii) As soon as available, and in any event within forty-five days after the end of each Fiscal Quarter (A) a consolidated balance sheet of Borrower and its Subsidiaries as of the end of such Fiscal Quarter, consolidated statements of their operations, and consolidated statements of their cash flows for the period from the beginning of the then current Fiscal Year to the end of such Fiscal Quarter, all in reasonable detail and prepared in accordance with GAAP, subject to changes resulting from normal year-end adjustments, each setting forth in comparative form the corresponding figures for the same Fiscal Quarter in the prior Fiscal Year, and (B) upon request of Administrative Agent, consolidating work sheets generated in connection with such consolidated balance sheet and statements, which need not be prepared in full accordance with GAAP. In addition Borrower will, together with each such set of financial statements and each set of financial statements furnished under subsection (b)(i) of this section, furnish a certificate in the form of Exhibit E, appropriately completed and signed by the Chief Financial Officer of Borrower. (iii) Promptly upon their becoming available, copies of all financial statements, reports, notices and proxy statements sent by any Related Person to its stockholders generally and all registration statements, periodic reports and other statements and schedules (other than transmittal letters) filed by any Related Person with any securities exchange, the Securities and Exchange Commission or any similar governmental authority. (iv) By (A) March 1 of each year, one or more engineering reports prepared as of the preceding January 1 by (1) with respect to Oil and Gas Properties consisting of Collateral, Approved Petroleum Engineers (provided, if Borrower is maintaining a BBB/Baa2 Debt Rating, such reports may be prepared by Borrower's or Torch's internal reserve engineers, subject, at the sole option of Administrative Agent, to external audit) and (2) with respect to Oil and Gas Properties not constituting Collateral, Borrower's or Torch's internal reserve engineers, and audited by Approved Petroleum Engineers (provided, if Borrower is maintaining a BBB/Baa2 Debt Rating, such audit shall not be mandatory and shall be at the sole option of Administrative Agent), and (B) by August 15 of each year (and within 45 days after any other Evaluation Date) an engineering report prepared by Borrower's or Torch's internal reserve engineers, in each case concerning all material Oil and Gas Properties owned by any Related Person which are located in or offshore of the United States and which have proved oil or gas reserves attributable thereto.

Each report shall also distinguish (or shall be delivered together with a certificate from an appropriate officer of Borrower which distinguishes) those properties treated in the report which are Collateral from those properties treated in the report which are not Collateral. (v) Promptly after entering into any Derivative Contracts (or any unwinding of any Derivative Contracts), at or about the same time, which together cover more than twenty-five percent (25%) of the Related Persons' anticipated production of oil and gas in any calendar year, notice that such contracts have been entered into and describing the general terms thereof. (c) Other Information; Inspections; Confidentiality. Each Related Person will furnish to Administrative Agent and each Lender any information which Administrative Agent may from time to time reasonably request in writing concerning any covenant, provision or condition of the Loan Documents or any matter in connection with the Related Persons' businesses and operations. Each Related Person will permit representatives appointed by Administrative Agent (including independent accountants, agents, attorneys, appraisers and any other Persons) to visit and inspect any of such Related Person's property, including its books of account, other books and records, and any facilities or other business assets, and to make extra copies therefrom and photocopies and photographs thereof, and to write down and record any information such representatives obtain, and each Related Person shall permit Administrative Agent or its representatives to investigate and verify the accuracy of the information furnished to Administrative Agent or any Lender in connection with the Loan Documents and to discuss all such matters with its officers, employees and representatives, in each case during normal business hours. Each of Administrative Agent and Lenders agrees that it will take all reasonable steps to keep confidential any proprietary information given to it by any Related Person, provided, however, that this restriction shall not apply to disclosures of information: (i) made in connection with any enforcement or defense by Administrative Agent or any Lender of its rights and remedies under the Loan Documents, (ii) which has at the time in question entered the public domain, (iii) which is required to be disclosed by law or by any order, rule or regulation (whether valid or invalid) of any court or governmental agency or authority, to (iv) Administrative Agent's or any Lender's Affiliates, auditors, attorneys, advisors, or agents (provided that Administrative Agent and each Lender shall be responsible for causing its own Affiliates, auditors, attorneys, advisors, or agents to comply with the foregoing confidentiality provisions), (v) or to any other Lender or to any purchaser or prospective purchaser of participations or other interests in any Loan or Loan Document (provided that any such purchaser or prospective purchaser has agreed to be bound by the foregoing confidentiality provisions). 47 (d) Notice of Material Events and Change of Address. Borrower will promptly notify Administrative Agent and each Lender: (i) of any event or condition having a Material Adverse Effect, (ii) of the occurrence of any Default or Borrowing Base Deficiency, (iii) of the acceleration of the maturity of any Indebtedness owed by any Related Person or of any default by any Related Person under any indenture, mortgage, agreement, contract or other instrument to which any of them is a party or by which any of them or any of their properties is bound, if such acceleration or default has a material probability of having a Material Adverse Effect, (iv) of the occurrence of any Termination Event known to Borrower, (v) of any claim of $1,000,000 or more, any notice of potential liability under any Environmental Laws which might exceed such amount, or any other material adverse claim, which is asserted against any Related Person or with respect to any Related Person's properties, and (vi) of the filing of any suit or proceeding against any Related Person in which an adverse decision would have a material probability of having a Material Adverse Effect. Upon the occurrence of any of the foregoing the Related Persons will take all necessary or appropriate steps to remedy promptly any such Default, acceleration, default or Termination Event, to protect against any such Material Adverse Effect or adverse claim, to defend any such suit or proceeding, and to resolve all controversies on account of any of the foregoing. Borrower will also notify Administrative Agent and Thompson & Knight, P.C., Administrative Agent's counsel (or such other counsel for Administrative Agent as may be designated by Administrative Agent) in writing at least thirty Business Days prior to the date that any Related Person changes its name or the location of its chief executive office or principal place of business or the place where it keeps its books and records concerning the Collateral, furnishing with such notice any necessary financing statement amendments or requesting Administrative Agent and its counsel to prepare the same. (e) Maintenance of Properties. Each Related Person will, in compliance with prudent industry practices, maintain, preserve, protect, and keep all Collateral and all of its other property in good condition and in material compliance with all applicable laws, rules and regulations, and will from time to time make all repairs, renewals and replacements needed to do the foregoing. Each Related Person will operate, or cause to be operated, all of its material Oil and Gas Properties in accordance with prudent industry practices. (f) Maintenance of Existence and Qualifications. Each Related Person which is a corporation or partnership will maintain and preserve its corporate or partnership existence (except for any mergers or consolidations expressly permitted by this Agreement and except for the dissolution of any Restricted Subsidiaries which no longer have any significant business or 48 assets) and its rights and franchises in full force and effect and will qualify to do business as a foreign corporation or partnership in all states or jurisdictions where required by applicable law, except where the failure so to qualify would not have a material probability of having a Material Adverse Effect. (g) Payment of Trade Liabilities, Taxes, etc. Each Related Person will (i) timely file all required tax returns; (ii) timely pay all taxes, assessments, and other governmental charges or levies imposed upon it or upon its income, profits or property; (iii) within ninety (90) days after the same becomes due pay all Liabilities owed by it on ordinary trade terms to vendors, suppliers and other Persons providing goods and services used by it in the ordinary course of its business; (iv) pay and discharge when due all other material Liabilities now or hereafter owed by it; and (v) maintain appropriate accruals and reserves for all of the foregoing in accordance with GAAP. Each Related Person may, however, delay paying or discharging any of the foregoing so long as it is in good faith contesting the validity thereof by appropriate proceedings and has set aside on its books adequate reserves therefor. (h) Insurance. Each Related Person will keep or cause to be kept adequately insured by financially sound and reputable insurers its surface equipment, vehicles and all other property of a character usually insured by similar Persons engaged in the same or similar businesses in the relevant area of operations. Each Related Person shall at all times maintain adequate insurance against its liability for injury to persons or property, which insurance shall be by financially sound and reputable insurers and shall provide the coverages usually maintained by similar Persons in the relevant area of operations. Upon written demand by Administrative Agent: (a) any insurance policies covering Collateral shall be endorsed (i) to provide for payment of losses to Administrative Agent for the account of Lenders as their interests may appear, pursuant to a mortgage clause (without contribution) of standard form made part of the applicable policy, (ii) to provide that such policies may not be cancelled, reduced or affected in any manner for any reason without fifteen days prior notice to Administrative Agent, (iii) to provide for insurance against fire, casualty and any other hazards normally insured against, in the amount of the full value (less a reasonable deductible not to exceed amounts customary in the industry for similarly situated businesses and properties) of the property insured, and (iv) to provide for any other matters which Administrative Agent may reasonably require; and (b) any insurance policies covering liability for injury to persons or property shall name Administrative Agent and Lenders as additional insured. (i) Payment of Expenses. Whether or not the transactions contemplated by this Agreement are consummated, Borrower will promptly (and in any event, within 30 days after any invoice or other statement or notice) pay all reasonable out- of-pocket costs and expenses (including reasonable attorneys' fees) incurred by or on behalf of (i) Administrative Agent in connection with the negotiation, preparation, execution and delivery of the Loan Documents, and any and all consents, waivers or other documents or instruments relating thereto, and the filing, recording, refiling and re-recording of any Loan Documents and any other documents or instruments or further assurances required to be filed or recorded or refiled or re-recorded by the terms of any Loan Document, and (ii) Administrative Agent or any Lender in connection with the defense or enforcement of the Loan Documents or the defense of Administrative Agent's or any 49 Lender's exercise of its rights thereunder (including reasonable costs and expenses of determining whether and how to carry out such defense or enforcement). (j) Performance on Borrower's Behalf. If any Related Person fails to pay any taxes, insurance premiums, expenses, attorneys' fees or other amounts it is required to pay under any Loan Document, Administrative Agent or any Lender may pay the same. Borrower shall immediately reimburse Administrative Agent or any such Lender for any such payments and each amount paid by Administrative Agent or any such Lender shall constitute an Obligation owed hereunder which is due and payable on the date such amount is paid by Administrative Agent or such Lender. (k) Interest. Borrower hereby promises to Administrative Agent and Lenders to pay interest at the Late Payment Rate on all Obligations which Borrower has in this Agreement promised to pay (including Obligations to pay fees or to reimburse or indemnify Administrative Agent or any Lender) and which are not paid when due. Such interest shall accrue from the date such Obligations become due until they are paid. (l) Compliance with Agreements and Law . Each Related Person will perform all obligations it is required to perform under the terms of each indenture, mortgage, deed of trust, security agreement, lease, franchise, agreement, contract or other instrument or obligation to which it is a party or by which it or any of its properties is bound, except where the failure to do so would not have a material probability of having a Material Adverse Effect. Each Related Person will conduct its business and affairs in compliance with all laws, regulations, and orders applicable thereto, including Environmental Laws, except where the failure to do so would not have a material probability of having a Material Adverse Effect. Without limitation of the foregoing, no Related Person will knowingly transport or arrange for the transportation or disposal of any Hazardous Material in violation of any Environmental Laws, and no Related Person will incur any material Liability under any Environmental Laws or in connection with the release into the environment, or the storage or disposal, of any Hazardous Materials. (m) Evidence of Compliance. Borrower will at its own expense furnish to each Lender all evidence which Administrative Agent from time to time reasonably requests in writing as to the accuracy and validity of or compliance with all representations, warranties and covenants made by any Related Person in the Loan Documents, the satisfaction of all conditions contained therein, and all other matters pertaining thereto. (n) Agreement to Deliver Security Documents. Borrower agrees to deliver, and to cause its Subsidiaries to deliver, to further secure the Obligations whenever requested by Administrative Agent in its sole and absolute discretion, deeds of trust, mortgages, chattel mortgages, security agreements, financing statements and other Security Documents in form and substance satisfactory to Administrative Agent, for the purpose of granting, confirming, and perfecting first and prior liens or security interests in Oil and Gas Properties with a value (as reasonably determined by Administrative Agent based upon the most- recent Engineering Report delivered by Borrower pursuant to Section 5.1(b)(iv)) at all times of not less than eighty-five percent (85%) of the aggregate value of all Borrowing Base Assets, together with legal opinions in form and substance reasonably satisfactory to Administrative Agent and its counsel confirming 50 that such Oil and Gas Properties are subject to Security Documents securing the Obligations that constitute and create legal, valid and duly perfected deed of trust or mortgage liens in such Oil and Gas Properties and assignments of and security interests in the oil and gas attributable to such Oil and Gas Properties and the proceeds thereof. Borrower also agrees to deliver, whenever requested by Administrative Agent in its sole and absolute discretion upon the occurrence and during the continuance of an Event of Default, favorable title opinions from legal counsel acceptable to Administrative Agent with respect to any such Oil and Gas Properties as may from time to time be designated by Administrative Agent, based upon abstract or record examinations to dates acceptable to Administrative Agent (a) stating that such Related Person has good and defensible title to such properties and interests, free and clear of all Liens other than Permitted Liens, (b) confirming that such properties and interests are subject to Security Documents securing the Obligations that constitute and create legal, valid and duly perfected first deed of trust or mortgage liens in such properties and interests and first priority assignments of and security interests in the oil and gas attributable to such properties and interests and the proceeds thereof, and (c) covering such other matters as Administrative Agent may request. (o) Perfection and Protection of Security. Each Related Person will from time to time Interests and Liens deliver to Administrative Agent any financing statements, continuation statements, extension agreements and other documents, properly completed and executed (and acknowledged when required) by the Related Persons in form and substance satisfactory to Administrative Agent, which Administrative Agent requests for the purpose of perfecting, confirming, or protecting any Liens or other rights in Collateral securing any Obligations. (p) Production Proceeds. Notwithstanding that, by the terms of the various Security Documents, Related Persons are and will be assigning to Administrative Agent and Lenders all of the "Production Proceeds" (as defined therein) accruing to the property covered thereby, so long as no Event of Default as described in Section 7.1(a), (b), (h) or (i) has occurred and is continuing, Related Persons may continue to receive from the purchasers of production all such Production Proceeds, subject, however, to the Liens created under the Security Documents, which Liens are hereby affirmed and ratified. Upon the occurrence and during the continuance of an Event of Default as described in Section 7.1(a), (b), (h) or (i), Administrative Agent and Lenders may exercise all rights and remedies granted under the Security Documents, including the right to obtain possession of all Production Proceeds then held by any Related Person or to receive directly from the purchasers of production all other Production Proceeds. In no case shall any failure, whether purposed or inadvertent, by Administrative Agent or Lenders to collect directly any such Production Proceeds constitute in any way a waiver, remission or release of any of their rights under the Security Documents, nor shall any release of any Production Proceeds by Administrative Agent or Lenders to any Related Person constitute a waiver, remission, or release of any other Production Proceeds or of any rights of Administrative Agent or Lenders to collect other Production Proceeds thereafter. Section 5.2. Negative Covenants. To conform with the terms and conditions under which each Lender is willing to have credit outstanding to Borrower, and to induce Administrative Agent and each Lender to enter into this Agreement and make the Loans, Borrower and each other Related Person which is a party hereto covenants and agrees that until 51 the full and final payment of the Obligations and the termination of this Agreement, unless Majority Lenders have previously agreed otherwise: (a) Guaranties and Indebtedness. No Restricted Subsidiary will at any time have any Liability under any guaranty of any Indebtedness other than guaranties of the Obligations and guaranties constituting Permitted Priority Senior Indebtedness. No Related Person will guarantee any Liability of any Unrestricted Subsidiary or of any Restricted Subsidiary which is obligated for Non-Recourse Indebtedness. No Related Person will directly or indirectly create, incur, assume, guarantee, or otherwise become or be liable with respect to any Indebtedness except: (i) the Obligations; (ii) Permitted Priority Senior Indebtedness owing by any Related Person; (iii) Additional Senior Indebtedness owing by Borrower (but no other Related Person) which is not Permitted Priority Senior Indebtedness; (iv) Subordinated Indebtedness owing by Borrower (but no other Related Person); (v) Indebtedness owing by Borrower (but no other Related Person) arising under Derivative Contracts, provided that such Derivative Contracts are in compliance with Section 5.2(g); (vi) Intercompany Indebtedness; and (vii) Non-Recourse Indebtedness owing by any Restricted Subsidiary, provided in each case that, both immediately before and after such Indebtedness is created, incurred, assumed, guaranteed, or otherwise becomes a liability of any such Related Person, no Borrowing Base Deficiency, Default under Section 5.2, or Event of Default exists (unless the proceeds of such Indebtedness are applied in such a way that no Borrowing Base Deficiency or Default exists immediately thereafter). For the purposes of this subsection, any Indebtedness owing by a Person at the time it becomes a Restricted Subsidiary shall be deemed to have been incurred at such time. (b) Prepayments of Subordinated Indebtedness. No Related Person will make any unscheduled payment on any Subordinated Indebtedness, except: (i) unscheduled payments of any Subordinated Indebtedness in exchange for, or out of the aggregate net cash proceeds of a substantially concurrent issuance and sale (other than to another Related Person) of Non- Redeemable Common Stock or of options or warrants giving the holders thereof only the right to acquire Non-Redeemable Common Stock; 52 (ii) unscheduled payments of any Subordinated Indebtedness in exchange for, or out of the aggregate net cash proceeds of a substantially concurrent incurrence (other than to another Related Person) of new Subordinated Indebtedness of Borrower that is permitted under subsection (iv) of the immediately preceding subsection (a), provided that such new Subordinated Indebtedness has a stated interest rate that is the same or less than the stated interest rate of the Subordinated Indebtedness being paid, purchased, redeemed, defeased, acquired, or retired, and has a weighted average life to maturity that is longer than the weighted average life to maturity of the Subordinated Indebtedness being paid, purchased, redeemed, defeased, acquired, or retired; and (iii) other unscheduled payments of any Subordinated Indebtedness, provided that Borrower must give Agent and each Lender at least forty-five (45) days' advance notice of its decision to do so and must defer making any such unscheduled payments until (1) Majority Lenders have determined whether or not to designate a new Borrowing Base pursuant to Section 2.11(c), (2) any Borrowing Base Deficiency (whether resulting from such a designation or previously existing) has been eliminated, and (3) no Default exists. Each Related Person will take all actions (such as, for example, reinvesting asset sales proceeds or using asset sales proceeds to pay the Obligations or Additional Senior Indebtedness) necessary to avoid becoming obligated to make any unscheduled payment on any Subordinated Indebtedness except as provided above. For the purpose of this subsection, Section 2.11, and the immediately following subsection (c), "unscheduled payment" means any payment on or purchase, redemption, defeasance, or other acquisition or retirement for value of any Subordinated Indebtedness or Additional Senior Indebtedness, excluding only principal payments and sinking fund payments which are scheduled to occur at specified times in the documents governing such Indebtedness without regard to the occurrence of any default, triggering event (such as asset sales, failure to maintain financial ratios, or a change of control) or other contingency. For the purpose of this subsection, the "weighted average life to maturity" of any Subordinated Indebtedness means, as of any date of determination, the quotient of (1) the sum of the products of (A) the number of years (and any portion thereof) from such date of determination to the date of each successive scheduled payment of principal on such Subordinated Indebtedness, times (B) the amount of each such scheduled payment, divided by (2) the sum of all such scheduled payments. (c) Prepayments of Additional Senior Indebtedness. No Related Person will make any unscheduled payment (as defined in the immediately preceding subsection (b)) on any Additional Senior Indebtedness at any time when a Borrowing Base Deficiency or Default exists (unless immediately after the making of such unscheduled payment no Borrowing Base Deficiency or Default will exist) or if such incurrence would cause any Borrowing Base Deficiency or Default to exist. Each Related Person will take all actions necessary to avoid becoming obligated to make any unscheduled payment on any Additional Senior Indebtedness in violation of the preceding sentence. (d) Limitation on Liens. No Related Person will create, assume or permit to exist any Lien other than Permitted Liens upon any of the properties or assets which it now owns or hereafter acquires. 53 (e) Limitation on Mergers, Issuances of Securities. Except as expressly provided in this subsection no Related Person will merge or consolidate with or into any other business entity. Any Unrestricted Subsidiary may be merged into or consolidated with another Unrestricted Subsidiary (including any Restricted Subsidiary which in compliance herewith is designated as an Unrestricted Subsidiary in anticipation of such merger) or any other Person that is not a Related Person. Any Person may be merged into or consolidated with (i) a Restricted Subsidiary, so long as a Restricted Subsidiary is the surviving business entity and no Default is caused by such merger and any guaranties then required by Article VI hereof are concurrently maintained or given, or (ii) Borrower, so long as Borrower is the surviving business entity and no Default is caused by such merger. Borrower will not hereafter issue any Equity Interests other than shares of Non-Redeemable Common Stock and any options or warrants giving the holders thereof only the right to acquire Non-Redeemable Common Stock. No Restricted Subsidiary will hereafter issue any Equity Interests, other than Permitted Preferred Trust Securities, and, to the extent not otherwise forbidden under the terms hereof, Equity Interests issued to another Related Person. Except as provided in Section 5.2(f), no Restricted Subsidiary which is a partnership will allow any diminution of Borrower's interest (direct or indirect) therein. (f) Limitation on Sales of Property. No Related Person will sell, lease, exchange, alienate, dispose of, or otherwise transfer any Collateral or any of its material assets or properties or any material interest therein to any Person other than a Related Person, except: (i) equipment or other tangible personal property which is worthless or obsolete or which is replaced by items of equal suitability and value. (ii) oil, gas and other hydrocarbons which are sold in the ordinary course of business after production or processing, and parcels of California surface real estate (excluding mineral rights) which are sold in the ordinary course of business. (iii) other assets and properties (including (A) Forward Sales/Production Payments, or (B) all, or any part, of the stock of or partnership interests in any of Borrower's Subsidiaries) which are sold or otherwise transferred on an arm's-length basis, provided that (1) the receipt of any consideration therefor other than cash will be deemed the making of an Investment by the Related Person which receives such consideration, and such sale or other transfer may be made only if such Investment can be made in compliance herewith after giving effect to such sale or transfer, and (2) any sale or other transfer to any of such Related Person's Affiliates must also be in compliance with Section 5.2(j). No Related Person will otherwise sell, transfer or otherwise dispose of capital stock of any Restricted Subsidiary except that any Restricted Subsidiary may sell or issue its own capital stock to the extent permitted under Section 5.2(e). No Related Person will discount, sell, pledge or assign any notes payable to it, accounts receivable or future income except to the extent expressly permitted under the Loan Documents. So long as no Default then exists or would be caused thereby, Administrative Agent will, at Borrower's request and expense (and each Lender hereby irrevocably authorizes Administrative Agent to) execute a release, satisfactory to Borrower and 54 Administrative Agent, of any Collateral so sold, leased, exchanged, alienated, disposed or otherwise transferred pursuant to clause (iii) above. (g) Derivative Contracts. No Restricted Subsidiary will be a party to or be bound by any Derivative Contract. Borrower will not be a party to or bound by any Derivative Contract, unless: (i) such Derivative Contract, at the time it is entered into (A) is not a speculative investment, and, unless it is a hedge of oil and gas production, qualifies under GAAP as a hedge of floating or fixed rate Indebtedness, or foreign currency needs, and (B) is entered into by Borrower in the ordinary course of the Related Persons' businesses. (ii) such Derivative Contract does not require any Related Person to provide any Lien to secure Borrower's obligations thereunder, except for Permitted Liens described in subsections (b) and (k) of the definition thereof in Section 1.1. (iii) all Derivative Contracts relating to the Related Persons' anticipated total sales (measured in unit volumes, not by sales price) of oil and gas in the ordinary course of their businesses (excluding any such production committed to fixed price sales contracts) do not, in the aggregate, cover amounts greater than the percentages of the Related Persons' production (determined looking only to anticipated production from reserves which are proved, developed producing reserves at the time in question and excluding any such production committed to fixed price sales contracts) for terms which are longer than those set out in the following table: Percentage of Anticipated Production Length of Contract Terms 0% to but not including 20% up to 7 years 20% to but not including 40% up to 5 years 40% to but not including 60% up to 3 years 60% to but not including 80% up to 1 year over 80% up to 3 months (h) Restricted Payments and Investments. No Related Person will incur any Liability to make any Investment in any Restricted Subsidiary which is obligated for Non-Recourse Indebtedness. No Related Person will make any Investment in any Restricted Subsidiary which is obligated for Non-Recourse Indebtedness at any time when, either immediately before or after giving effect to such Investment, any Borrowing Base Deficiency, Default under Section 5.2, or Event of Default would exist. No Related Person will declare, make or incur any Liability to make any Restricted Payment or any Restricted Investment (including the sale, issuance or entering into of any Allowed Put), unless both immediately before and after giving effect to such action: (i) no Borrowing Base Deficiency, Default under Section 5.2, or Event of Default would exist, and 55 (ii) the sum of the aggregate amount of Restricted Investments (valued immediately after such action), plus the aggregate amount of Restricted Payments of the Related Persons declared or made during the period commencing on January 1, 1996, and ending on the date such Restricted Payment or Restricted Investment is declared or made, inclusive, would not exceed the sum of (1) $10,000,000, plus (2) 50% of Adjusted Net Income for such period (or minus 100% of Adjusted Net Income for such period if Adjusted Net Income for such period is a loss), plus (3) twenty-five percent (25%) of the aggregate proceeds (whether or not in cash, but net of transaction costs) in excess of $130,000,000 received after December 31, 1995 and prior to January 1, 1998 from sales, exchanges, conversions or other issuances of Equity Interests of any kind, including the TECONS and other Permitted Preferred Trust Securities, by Borrower or any of its Restricted Subsidiaries (other than from issuances to each other which are permitted hereunder), plus (4) fifty percent (50%) of the aggregate proceeds (whether or not in cash, but net of transaction costs) received on or after January 1, 1998 and through the end of such period from sales, exchanges, conversions or other issuances of Equity Interests of any kind, including Permitted Preferred Trust Securities, by Borrower or any of its Restricted Subsidiaries (other than from issuances to each other which are permitted hereunder), plus (5) the aggregate net cash proceeds received during such period by the Related Persons, after elimination of inter-company transactions between themselves, constituting a return of capital from any Restricted Investment Notwithstanding the foregoing subsection (ii), Borrower may make the following Restricted Payments and Restricted Investments (which will nonetheless be included in all calculations thereafter made under such subsection (ii)): (A) the payment of any dividend on any other capital stock of any Related Person within 60 days after the date of declaration thereof, if at such declaration date such declaration complied with the foregoing subsections (i) and (ii) (and such payment shall be deemed to have been paid on such date of declaration for purposes of any calculation required by the provisions of such subsection (ii)). (i) Limitation on Acquisitions, New Businesses, and Margin Stock. No Related Person will: (i) make any expenditure or commitment or incur any obligation or enter into or engage in any transaction except in the ordinary course of business, (ii) engage directly or indirectly in any business other than the Oil and Gas Business, the development or sale of California surface real estate (excluding mineral rights) currently owned or as part of future 56 acquisitions of Oil and Gas Properties in California, or activities ancillary to the foregoing, (iii) make any significant acquisitions of or investments in any properties other than Oil and Gas Properties, the foregoing California real estate, and ancillary properties used or useful in the Oil and Gas Business. Borrower will not at any time, directly or indirectly, own "margin stock" (as such term is defined in Regulation U promulgated by the Board of Governors of the Federal Reserve System) which constitute more than twenty-five percent of the value of Borrower's assets, and Borrower will not use the proceeds of any Advances to acquire five percent or more of any class of publicly-traded Equity Interests issued by any Person. (j) Transactions with Affiliates. No Related Person will engage in any material transaction (including any series of related transactions, but excluding any extension of credit to employees which is described in subsection (c) of the definition herein of "Restricted Investment") with any of its Affiliates (other than another Related Person) unless (i) the terms of such transaction are at least as favorable to it as those which would be obtainable at the time in arm's-length dealings with Persons who are not its Affiliates, and (ii) if such transaction involves payments in excess of $5,000,000, a majority of those members of Borrower's Board of Directors who are not related to such Affiliate have approved such transaction. (k) Certain Prohibited Contracts; Torch Agreements; Multiemployer ERISA Plans. Except as expressly provided for in the Loan Documents, no Related Person will, directly or indirectly, enter into, create, or otherwise allow to exist any contract or other consensual restriction on the ability of any Restricted Subsidiary to: (i) pay dividends or make other distributions to Borrower or another Restricted Subsidiary, (ii) redeem Equity Interests held in it by Borrower or another Restricted Subsidiary, (iii) repay loans and other Indebtedness owing by it to Borrower or another Restricted Subsidiary, or (iv) transfer any of its assets to Borrower or another Restricted Subsidiary (other than leased assets or licenses which require the lessor's or licensor's consent to any transfer). No Related Person will enter into any "take-or-pay" contract or other contract or arrangement for the purchase of goods or services which obligates it to pay for such goods or service regardless of whether they are delivered or furnished to it. Borrower will (1) promptly notify Administrative Agent and each Lender in writing not less than thirty days prior to any proposed amendment or supplement to or replacement or termination of the Torch Agreements or any related marketing agreement, and (2) from time to time upon request of Administrative Agent or any Lender, permit representatives appointed by Administrative Agent or such Lender to visit Borrower's offices and review any such proposed or final amendment, supplement or replacement. No Related Person will incur any obligation to contribute to any "multiemployer plan" as defined in Section 4001 of ERISA. (l) Unrestricted Subsidiaries. Borrower will not have any Subsidiary that is neither a Restricted Subsidiary nor an Unrestricted Subsidiary. Borrower will insure that no Unrestricted Subsidiary creates, incurs, assumes or otherwise becomes liable with respect to any Indebtedness other than Non-Recourse Indebtedness. Borrower will (without violating Section 5.2(h) or any other provision of any Loan Document) insure that each Unrestricted Subsidiary complies with each indenture, mortgage, deed of trust, security agreement, lease, franchise, agreement, contract or other instrument or obligation to which such Unrestricted Subsidiary is a party or by which it or any of its properties is bound, and with all laws, regulations, and orders applicable to such Unrestricted Subsidiary or its properties, business and affairs, including Environmental Laws, if 57 such Unrestricted Subsidiary's failure so to comply would impose any Liability on any Related Person, require any Related Person to pay or perform any Liability owing by any Unrestricted Subsidiary, or otherwise have a material probability of having a Material Adverse Effect. Borrower will (without violating Section 5.2(h) or any other provision of any Loan Document) insure that no Unrestricted Subsidiary takes, or omits to take, any action if such action or omission would cause Borrower to be unable to remake its representations and warranties hereunder. (m) EBITDAX to Fixed Charges. At the end of any Fiscal Quarter, either: (i) the EBITDAX/Fixed Charge Ratio will not be less than 2.0 to 1 or (ii) if such Fiscal Quarter ends on or prior to March 31, 2000, the Adjusted EBITDAX/Fixed Charge Ratio will not be less than 2.5 to 1. (n) Indebtedness to Capitalization. The Debt to Capitalization Ratio shall not exceed 0.65 to 1 at any time. ARTICLE VI - Subsidiary Guaranties and Subordination Section 6.1 Subsidiary Guarantors. Any Subsidiary of Borrower, whether now existing or hereafter created or acquired or otherwise coming into existence after the date hereof, that shall at any time qualify as a Material Restricted Subsidiary hereunder shall promptly become a party to this Agreement by executing and delivering to Administrative Agent a supplement hereto in the form attached hereto as Exhibit G, with such modifications therein as Administrative Agent shall from time to time reasonably specify. Each such Material Restricted Subsidiary shall deliver to Administrative Agent, simultaneously with its delivery of such supplement, written evidence satisfactory to Administrative Agent and its counsel that such Material Restricted Subsidiary has taken all corporate or partnership action necessary to duly approve and authorize its execution, delivery and performance thereof and of any other documents which it is required to execute. Section 6.2. Guaranty. (a) Each Subsidiary Guarantor, by becoming a party to this Agreement, irrevocably, absolutely, and unconditionally guarantees to Administrative Agent and each Lender the prompt, complete, and full payment when due, and no matter how the same shall become due, of (i) each Note, including all principal, all interest thereon and all other sums payable thereunder, and (ii) all other sums payable under this Agreement and the other Loan Documents, whether for principal, interest, fees or otherwise. Without limiting the generality of the foregoing, each Subsidiary Guarantor's liability hereunder shall extend to and include all post-petition interest, expenses, and other duties and liabilities of Borrower described above in this subsection (a), or below in the following subsection (b), which would be owed by Borrower but for the fact that they are unenforceable or not allowable due to the existence of a bankruptcy, reorganization, or similar proceeding involving Borrower. 58 (b) Each Subsidiary Guarantor hereby irrevocably, absolutely, and unconditionally guarantees to Administrative Agent and each Lender the prompt, complete and full performance, when due, and no matter how the same shall become due, of all obligations and undertakings of Borrower to Administrative Agent or Lenders under, by reason of, or pursuant to any of the Loan Documents. (c) If Borrower shall for any reason fail to pay any Obligation, as and when such Obligation shall become due and payable, whether at its stated maturity, as a result of the exercise of any power to accelerate, or otherwise, each Subsidiary Guarantor will, forthwith upon demand by Administrative Agent, pay such Obligation in full to Administrative Agent for the benefit of Administrative Agent or the Lenders to whom such Obligation is owed. If Borrower shall for any reason fail to perform promptly any Obligation, each Subsidiary Guarantor will, forthwith upon demand by Administrative Agent, cause such Obligation to be performed or, if specified by Administrative Agent, provide sufficient funds, in such amount and manner as Administrative Agent shall in good faith determine, for the prompt, full and faithful performance of such Obligation by Administrative Agent or such other Person as Administrative Agent shall designate. (d) If either Borrower or any Subsidiary Guarantor fails to pay or perform any Obligation as described in the immediately preceding subsections (a), (b), or (c), each Subsidiary Guarantor will incur the additional obligation to pay to Administrative Agent, and each Subsidiary Guarantor will forthwith upon demand by Administrative Agent pay to Administrative Agent, the amount of any and all expenses, including reasonable fees and disbursements of Administrative Agent's counsel and of any experts or agents retained by Administrative Agent, which Administrative Agent may incur as a result of such failure. (e) It is the intention of all parties that the guarantees by each Subsidiary Guarantor under this Article VI not constitute fraudulent transfers or fraudulent conveyances for purposes of the federal Bankruptcy Code, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act, or any similar federal or state law. Therefore, and notwithstanding any provision to the contrary in this Agreement, the obligations of each Subsidiary Guarantor from time to time owing under this Agreement shall be limited to the maximum amount as will (after giving effect to all other Liabilities of such Subsidiary Guarantor, including any Liability under any guarantee of the 1996 Notes or the 1998 Notes, if any, and any adjustments to such Liability from time to time under Section 13.4 of the 1996 Indenture or Section 13.4 of the 1998 Indenture, and after giving effect to all assets of such Subsidiary Guarantor consisting of rights to subrogation, reimbursement, indemnity, exoneration or contribution) result in such obligations of such Subsidiary Guarantor not constituting such a fraudulent conveyance or fraudulent transfer. Section 6.3. Unconditional Guaranty. (a) No action which Administrative Agent or any Lender may take or omit to take in connection with any of the Loan Documents, any of the Obligations (or any other Liabilities owing by Borrower to Administrative Agent or any Lender), or any Security, and no course of dealing of Administrative Agent or any Lender with any Related Person or any other Person, shall release or diminish any Subsidiary Guarantor's obligations, liabilities, agreements or duties 59 hereunder or afford any Subsidiary Guarantor any recourse against Administrative Agent or any Lender, regardless of whether any such action or inaction may increase any risks to or liabilities of Administrative Agent or any Lender or any Related Person or increase any risk to or diminish any safeguard of any Security. Without limiting the foregoing, each Subsidiary Guarantor hereby expressly agrees that Administrative Agent and Lenders may, from time to time, without notice to or the consent of any Subsidiary Guarantor, do any or all of the following: (i) consent to, or participate in making, any amendment, change or modification, in whole or in part, to any one or more of the Loan Documents, and give or refuse to give any waivers or other indulgences with respect thereto. (ii) neglect, delay, fail, or refuse to take or prosecute any action for the collection or enforcement of any of the Obligations, to foreclose or take or prosecute any action in connection with any Security or Loan Document, to bring suit against any Related Person or any other Person, or to take any other action concerning the Obligations or the Loan Documents. (iii) accelerate, change, rearrange, extend, or renew the time, rate, terms, or manner for payment or performance of any one or more of the Obligations (whether for principal, interest, fees, expenses, indemnifications, affirmative or negative covenants, or otherwise). (iv) compromise or settle any unpaid or unperformed Obligation or any other obligation or amount due or owing, or claimed to be due or owing, under any one or more of the Loan Documents. (v) take, exchange, amend, eliminate, surrender, release, or subordinate any or all Security for any or all of the Obligations, accept additional or substituted Security therefor, and perfect or fail to perfect Administrative Agent's or Lenders' rights in any or all Security. (vi) discharge, release, substitute or add Subsidiary Guarantors or other guarantors of the Obligations. (vii) apply all amounts received from the Related Persons or others, or from any Security for any of the Obligations, as required herein or as Administrative Agent or Lenders may otherwise determine, without in any way being required to marshall Security or assets or to apply all or any part of such amounts upon any particular Obligations. (b) No action or inaction of any Related Person or any other Person, and no change of law or circumstances, shall release or diminish any Subsidiary Guarantor's obligations, liabilities, agreements, or duties hereunder or afford any Subsidiary Guarantor any recourse against Administrative Agent or any Lender. Without limiting the foregoing, the obligations, liabilities, agreements, and duties of each Subsidiary Guarantor under this Agreement shall not be released, diminished, impaired, reduced, or affected by the occurrence of any or all of the following from 60 time to time, even if occurring without notice to or without the consent of any Subsidiary Guarantor: (i) any voluntary or involuntary liquidation, dissolution, sale of all or substantially all assets, marshalling of assets or liabilities, receivership, conservatorship, assignment for the benefit of creditors, insolvency, bankruptcy, reorganization, arrangement, or composition of any Related Person or any other proceedings involving any Related Person or any of the assets of any Related Person under laws for the protection of debtors, or any discharge, impairment, modification, release, or limitation of the liability of, or stay of actions or lien enforcement proceedings against, any Related Person, any properties of any Related Person, or the estate in bankruptcy of any Related Person in the course of or resulting from any such proceedings. (ii) the failure by Administrative Agent or any Lender to file or enforce a claim in any proceeding described in the immediately preceding subsection (i) or to take any other action in any proceeding to which any Related Person is a party. (iii) the release by operation of law of any Related Person from any of the Obligations or any other obligations to Administrative Agent or any Lender. (iv) the invalidity, deficiency, illegality, or unenforceability of any of the Obligations or the Loan Documents, in whole or in part, any bar by any statute of limitations or other law of recovery on any of the Obligations, or any defense or excuse for failure to perform on account of force majeure, act of God, casualty, impossibility, impracticability, or other defense or excuse whatsoever. (v) the failure of any Related Person or any other Person to sign any guaranty or other instrument or agreement within the contemplation of any Related Person, Administrative Agent or any Lender. (vi) without limiting any of the foregoing, any fact or event (whether or not similar to any of the foregoing) which in the absence of this provision would or might constitute or afford a legal or equitable discharge or release of or defense to a guarantor or surety other than the actual, full and final payment and performance of the Obligations in accordance with their terms or the release of such Subsidiary Guarantor pursuant to Section 6.8. (c) Administrative Agent and Lenders may invoke the benefits of this Agreement against any one or more Subsidiary Guarantors before pursuing any remedies against any Related Person or any other Person and before proceeding against any Security now or hereafter existing for the payment or performance of any of the Obligations. Administrative Agent and Lenders may maintain an action against any Subsidiary Guarantor without joining any other Related Person therein and without bringing a separate action against any other Related Person. (d) If any payment to Administrative Agent or any Lender by any Related Person is held to constitute a preference or a voidable transfer under applicable state or federal laws, or if for 61 any other reason Administrative Agent or any Lender is required to refund such payment to the payor thereof or to pay the amount thereof to any other Person, such payment to Administrative Agent or such Lender shall not constitute a release of any Subsidiary Guarantor from any liability hereunder, and each Subsidiary Guarantor agrees to pay such amount to Administrative Agent or such Lender on demand and agrees and acknowledges that this Agreement shall continue to be effective or shall be reinstated, as the case may be, to the extent of any such payment or payments. Any transfer by subrogation which is made as contemplated in Section 6.6 prior to any such payment or payments shall (regardless of the terms of such transfer) be automatically voided upon the making of any such payment or payments, and all rights so transferred shall thereupon revert to and be vested in Administrative Agent and Lenders. (e) This Article VI constitutes a continuing guaranty and shall apply to and cover all Obligations and renewals and extensions thereof and substitutions therefor from time to time. Section 6.4. Waivers. Each Subsidiary Guarantor hereby waives, with respect to the Obligations, this Agreement, and the other Loan Documents: (a) notice of the incurrence of any Obligation by Borrower, and notice of any kind concerning the assets, liabilities, financial condition, creditworthiness, businesses, prospects, or other affairs of Borrower (it being understood and agreed that: (i) each Subsidiary Guarantor shall take full responsibility for informing itself of such matters, (ii) neither Administrative Agent nor any Lender shall have any responsibility of any kind to inform any Subsidiary Guarantor of such matters, and (iii) Administrative Agent and Lenders are hereby authorized to assume that each Subsidiary Guarantor, by virtue of its relationships with Borrower, has full and complete knowledge of such matters whenever Lenders extend credit to Borrower or take any other action which may change or increase any Subsidiary Guarantor's liabilities or losses hereunder). (b) notice that Administrative Agent, any Lender, any Related Person, or any other Person has taken or omitted to take any action under any Loan Document or any other agreement or instrument relating thereto or relating to any Obligation. (c) notice of acceptance of the guarantee provided in this Article VI, and all rights of any Subsidiary Guarantor under (S)3.605 or (S)34.02 of the Texas Business and Commerce Code. (d) demand, presentment for payment, and notice of demand, dishonor, nonpayment, or nonperformance. (e) notice of intention to accelerate, notice of acceleration, protest, notice of protest, notice of any exercise of remedies (as described in the following section or otherwise), and all other notices of any kind whatsoever. Section 6.5. Exercise of Remedies. Administrative Agent and Lenders shall have the right to enforce, from time to time and in any order, any rights, powers and remedies which they may have under the Loan Documents or otherwise, including judicial foreclosure, the exercise of rights of power of sale, the taking of a deed or assignment in lieu of foreclosure, the appointment 62 of a receiver to collect rents, issues and profits, the exercise of remedies against personal property, or the enforcement of any assignment of leases, rentals, oil or gas production, or other properties or rights, whether real or personal, tangible or intangible; and each Subsidiary Guarantor shall be liable to Administrative Agent and each Lender hereunder for any deficiency resulting from the exercise by Administrative Agent or any Lender of any such right or remedy even though any rights which such Subsidiary Guarantor may have against Borrower or others may be destroyed or diminished by exercise of any such right or remedy. No failure on the part of Administrative Agent or any Lender to exercise, and no delay in exercising, any right hereunder or under any other Loan Document shall operate as a waiver thereof; nor shall any single or partial exercise of any right preclude any other or further exercise thereof or the exercise of any other right. The rights, powers and remedies of Administrative Agent and each Lender provided herein and pursuant to the other Loan Documents are cumulative and are in addition to, and not exclusive of, any other rights, powers or remedies provided by law or in equity. The rights of Administrative Agent and each Lender hereunder are not conditional or contingent on any attempt by Administrative Agent or any Lender to exercise any of its rights under any other Loan Document against any Related Person or any other Person. Section 6.6. Delayed Subrogation. Until all of the Obligations have been paid and performed in full, no Subsidiary Guarantor shall have any right to exercise any right of subrogation, reimbursement, indemnity, exoneration, contribution or any other claim which it may now or hereafter have against or to any Related Person or any Security in connection with this Agreement (including any right of contribution or subrogation under (S)3.116 or (S)34.04 of the Texas Business and Commerce Code), and each Subsidiary Guarantor hereby waives any rights to enforce any remedy which any Subsidiary Guarantor may have against Borrower or any other Subsidiary Guarantor and any right to participate in any Security until such time. If any amount shall be paid to any Subsidiary Guarantor on account of any such subrogation or other rights, any such other remedy, or any Security at any time when all of the Obligations and all other expenses guaranteed pursuant hereto shall not have been paid in full, such amount shall be held in trust for the benefit of Administrative Agent and Lenders, shall be segregated from the other funds of such Subsidiary Guarantor, and shall forthwith be paid over to Administrative Agent to be held by Administrative Agent as collateral for, or then or at any time thereafter applied in whole or in part by Administrative Agent against, all or any portion of the Obligations, whether matured or unmatured, in such order as Administrative Agent shall elect. If any Subsidiary Guarantor shall make payment to Administrative Agent of all or any portion of the Obligations and if all of the Obligations shall be finally paid in full, Administrative Agent will, at such Subsidiary Guarantor's request and expense, execute and deliver to such Subsidiary Guarantor (without recourse, representation or warranty) appropriate documents necessary to evidence the transfer by subrogation to such Subsidiary Guarantor of an interest in the Obligations resulting from such payment by such Subsidiary Guarantor, provided that such transfer shall be subject to Section 6.3(d). Section 6.7. Subordination. Each Restricted Subsidiary which at any time is a party hereto hereby subordinates and makes inferior to the Obligations any and all Liabilities now or at any time hereafter owed by Borrower to such Restricted Subsidiary. Each Restricted Subsidiary agrees that during the continuance of any Event of Default it will neither permit Borrower to repay such Liabilities or 63 any part thereof nor accept payment from Borrower of such Liabilities or any part thereof. If any such Restricted Subsidiary receives any such payment, the amount so paid shall be held in trust for the benefit of Lenders, shall be segregated from the other funds of such Restricted Subsidiary, and shall forthwith be paid over to Administrative Agent to be held by Administrative Agent as collateral for, or then or at any time thereafter applied in whole or in part by Administrative Agent against, all or any portions of the Obligations in such order as Administrative Agent and Majority Lenders shall elect. Section 6.8. Release of Guarantor. (a) Upon any sale or disposition (by merger or otherwise) of a Subsidiary Guarantor to a Person other than Borrower or another Subsidiary Guarantor, pursuant to a transaction that is otherwise permitted by and in compliance with the Loan Documents, such Subsidiary Guarantor shall automatically and without further action by Administrative Agent or any Lender be released from its obligations as a Subsidiary Guarantor hereunder. The Administrative Agent shall (and each Lender hereby irrevocably authorizes Administrative Agent to) deliver an appropriate instrument evidencing such release upon (i) compliance with all provisions of the Loan Documents with respect to such sale or disposition and (ii) receipt of a request from Borrower certifying such compliance. (b) Each Subsidiary Guarantor that may from time to time be designated as an Unrestricted Subsidiary in accordance with the provisions of this Agreement shall be released from its guarantee as a Subsidiary Guarantor hereunder for so long as it remains an Unrestricted Subsidiary. The Administrative Agent shall (and each Lender hereby irrevocably authorizes Administrative Agent to) deliver an appropriate instrument evidencing such release upon (i) the satisfaction of all requirements hereunder with respect to any such designation and (ii) receipt by Administrative Agent of certified resolutions of Borrower's Board of Directors designating such Subsidiary Guarantor as an Unrestricted Subsidiary. (c) If at any time any Subsidiary Guarantor shall no longer qualify as a Material Restricted Subsidiary, then, provided that an Event of Default shall not have occurred and be continuing, upon the request of Borrower to Administrative Agent, Administrative Agent shall (and each Lender hereby irrevocably authorizes Administrative Agent to) release such Subsidiary Guarantor from its obligations as a Subsidiary Guarantor hereunder. ARTICLE VII - Events of Default and Remedies Section 7.1. Events of Default. Each of the following events constitutes an Event of Default under this Agreement: (a) Any Related Person fails to pay the principal amount of any Obligation owed by it when due and payable, whether at a date for the payment of a fixed installment or as a contingent or other payment becomes due and payable or as a result of acceleration or otherwise;

(f) Any Related Person (i) fails to pay any portion, when such portion is due, of any Indebtedness (other than the Obligations) owing by it (whether as principal, guarantor or otherwise) in an aggregate amount in excess of $5,000,000, or (ii) breaches or defaults in the performance of any agreement or instrument by which any such Indebtedness is issued, evidenced, governed, or secured, and any such failure, breach or default continues beyond any applicable period of grace provided therefor;

Section 7.2 Acceleration; Other Remedies. Upon the occurrence of an Event of Default described in subsection (i)(i), (i)(ii) or (i)(iii) of Section 7.1 with respect to Borrower, all of the Obligations shall thereupon be immediately due and payable, without demand, presentment, notice of demand or of dishonor and nonpayment, protest, notice of protest, notice of intention to accelerate, declaration or notice of acceleration, or any other notice or declaration of any kind, all of which are hereby expressly waived by Borrower and each Related Person who at any time ratifies or approves this Agreement. Upon any such acceleration, any obligation of any Lender to make any further Advances shall be terminated. During the continuance of any other Event of Default, Administrative Agent may (provided it has received the consent of Majority Lenders), at any time and from time to time and without notice to Borrower or any other Related Person, do either or both of the following: (a) terminate any obligation of Lenders to make Advances hereunder, and (b) declare any or all of the Obligations immediately due and payable, and all such Obligations shall thereupon be immediately due and payable, without demand, presentment, notice of demand or of dishonor and nonpayment, protest, notice of protest, notice of intention to accelerate, declaration or notice of acceleration, or any other notice or declaration of any kind, all of which are hereby expressly waived by Borrower and each Related Person who at any time ratifies or approves this Agreement. 66 After the occurrence of any Event of Default Administrative Agent may, on behalf of itself and Lenders (i) protect and enforce their rights under the Loan Documents by any appropriate proceedings, including proceedings to obtain specific performance of any covenant or agreement contained in any Loan Document or to enforce any other legal or equitable right, and (ii) enforce and foreclose on the Liens upon Collateral evidenced by the Security Documents in any manner provided therein or provided for by law. All rights, remedies and powers conferred upon Administrative Agent and Lenders under the Loan Documents shall be deemed cumulative and not exclusive of any other rights, remedies or powers available under the Loan Documents or at law or in equity; provided that no Lender shall individually give any notice to any holder of Subordinated Indebtedness (or any trustee for such holders) which would have the effect of suspending payments on such Subordinated Indebtedness, and any such notice shall be given only by Administrative Agent with the consent of Majority Lenders. Section 7.3. Indemnity. As used in this section the term "Indemnified Parties" refers to Administrative Agent, Documentation Agent, each Lender, and each director, officer, agent, attorney, employee, representative and Affiliate of Administrative Agent, Documentation Agent or any Lender. Borrower hereby agrees to indemnify each Indemnified Party, upon demand, from and against any and all liabilities, obligations, claims, losses, damages, penalties, fines, actions, judgments, suits, settlements, costs, expenses or disbursements (including reasonable fees of attorneys, accountants, experts and advisors) of any kind or nature whatsoever (in this section collectively called "liabilities and costs") which to any extent (in whole or in part) may be imposed on, incurred by, or asserted against such Indemnified Party growing out of, resulting from or in any other way associated with any of the Loan Documents and the transactions and events (including the enforcement or defense thereof) at any time associated therewith or contemplated therein (including any violation or noncompliance with any Environmental Laws by any Related Person or any liabilities or duties of any Related Person or any Indemnified Party with respect to Hazardous Materials found in or released into the environment). THE FOREGOING INDEMNITIES SHALL EXTEND TO THE INDEMNIFIED PARTIES NOTWITHSTANDING THE SOLE OR CONCURRENT NEGLIGENCE OF EVERY KIND OR CHARACTER WHATSOEVER, WHETHER ACTIVE OR PASSIVE, WHETHER AN AFFIRMATIVE ACT OR AN OMISSION, INCLUDING ALL TYPES OF NEGLIGENT CONDUCT IDENTIFIED IN THE RESTATEMENT (SECOND) OF TORTS, OF ONE OR MORE OF THE INDEMNIFIED PARTIES OR BY REASON OF STRICT LIABILITY IMPOSED WITHOUT FAULT ON ONE OR MORE OF THE INDEMNIFIED PARTIES, unless and only to the extent that it shall be judicially determined (including without limitation by agreed alternative dispute resolution) that such liabilities and costs were proximately caused by the gross negligence or willful misconduct of any Indemnified Party, in which event the foregoing indemnities (a) shall continue for the benefit of the other Indemnified Parties in all respects, and (b) shall also continue for the benefit of such Indemnified Party but shall only extend to those portions of the liabilities and costs that are 67 not determined to have been proximately caused by the gross negligence or willful misconduct of such Indemnified Party. Section 7.4. Bank Accounts; Offset. In this section Borrower and Subsidiary Guarantors which are parties hereto are each called a "Grantor". To secure the repayment of the Obligations, each Grantor hereby grants to Administrative Agent and to each Lender a right of offset, which shall be in addition to all other interests and rights of Administrative Agent or any Lender at common law, under the Loan Documents, or otherwise, and which shall be upon and against (a) any and all moneys, securities or other property (and the proceeds therefrom) of such Grantor now or hereafter held or received by or in transit to Administrative Agent or any Lender from or for the account of such Grantor, whether for safekeeping, custody, pledge, transmission, collection or otherwise, (b) any and all deposits (general or special, time or demand, provisional or final) of such Grantor with Administrative Agent or any Lender, and (c) any other credits and claims of such Grantor at any time existing against Administrative Agent or any Lender, including claims under certificates of deposit. At any time and from time to time during the continuation of any Event of Default, each of Administrative Agent and Lenders is hereby authorized to offset against the Obligations then due and payable (in either case without notice to such Grantor) any and all items hereinabove referred to. If Administrative Agent or any Lender ever exercises such right of offset, it shall give Borrower (or the other affected Grantor) notice of such offset promptly thereafter, but failure or delay in giving such notice shall in no way affect the validity or enforceability of such offset. ARTICLE VIII - Administrative Agent Section 8.1. Appointment and Authority. Each Lender hereby irrevocably authorizes Administrative Agent, and Administrative Agent hereby undertakes, to receive payments of principal, interest and other amounts due hereunder as specified herein and to take all other actions and to exercise such powers under the Loan Documents as are specifically delegated to Administrative Agent by the terms hereof or thereof, together with all other powers reasonably incidental thereto. The relationship of Administrative Agent to Lenders is only that of one commercial bank acting as administrative agent for others, and nothing in the Loan Documents shall be construed to constitute Administrative Agent a trustee or other fiduciary for any holder of any of the Notes or of any participation therein nor to impose on Administrative Agent duties and obligations other than those expressly provided for in the Loan Documents. With respect to any matters not expressly provided for in the Loan Documents and any matters which the Loan Documents place within the discretion of Administrative Agent, Administrative Agent shall not be required to exercise any discretion or take any action, and it may request instructions from Lenders with respect to any such matter, in which case it shall be required to act or to refrain from acting (and shall be fully protected and free from liability to all Lenders in so acting or refraining from acting) upon the instructions of Majority Lenders (including itself), provided, however, that Administrative Agent shall not be required to take any action which exposes it to a risk of personal liability that it considers unreasonable or which is contrary to the Loan Documents or to applicable law. Upon receipt by Administrative Agent from Borrower of any communication calling for action on the part of Lenders or upon notice from any Lender to Administrative Agent of any Default or Event of Default, Administrative Agent shall promptly notify each Lender thereof. 68 Section 8.2. Exculpation, Administrative Agent's Reliance, Etc. Neither Administrative Agent nor any of its directors, officers, agents, attorneys, or employees shall be liable for any action taken or omitted to be taken by any of them under or in connection with the Loan Documents, INCLUDING THEIR NEGLIGENCE OF ANY KIND, except that each shall be liable for its own gross negligence or willful misconduct. Without limiting the generality of the foregoing, Administrative Agent (a) may treat the payee of any Note as the holder thereof until Administrative Agent receives written notice of the assignment or transfer thereof in accordance with this Agreement, signed by such payee and in form satisfactory to Administrative Agent; (b) may consult with legal counsel (including counsel for 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 warranty or representation to any Lender and shall not be responsible to any Lender for any statements, warranties or representations made in or in connection with the Loan Documents, or for the adequacy, accuracy or completeness of any title, environmental or other review or evidence referred to in Article III; (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 the Loan Documents on the part of any Related Person or to inspect the property (including the books and records) of any Related Person; (e) shall not be responsible to any Lender for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of any Loan Document or any instrument or document furnished in connection therewith; (f) may rely upon the representations and warranties of the Related Persons and the Lenders in exercising its powers hereunder; and (g) shall incur no liability under or in respect of the Loan Documents by acting upon any notice, consent, certificate or other instrument or writing (including any telecopy, telegram, cable or telex) believed by it to be genuine and signed or sent by the proper Person or Persons. Section 8.3. Lenders' Credit Decisions. Each Lender acknowledges that it has, independently and without reliance upon Administrative Agent or any other Lender, made its own analysis of Borrower and the transactions contemplated hereby and its own independent decision to enter into this Agreement and the other Loan Documents. Each Lender also acknowledges that it will, independently and without reliance upon Administrative Agent or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under the Loan Documents. Section 8.4. Indemnification. As used in this section the term "Indemnified Parties" refers to Administrative Agent and each director, officer, agent, attorney, employee, representative and Affiliate of Administrative Agent. Each Lender hereby agrees to indemnify each Indemnified Party, upon demand, from and against any and all liabilities, obligations, claims, losses, damages, penalties, fines, actions, judgments, suits, settlements, costs, expenses or disbursements (including reasonable fees of attorneys, accountants, experts and advisors) of any kind or nature whatsoever (in this section collectively called "liabilities and costs") which to any extent (in whole or in part) may be imposed on, incurred by, or asserted against such Indemnified Party growing out of, resulting from or in any other way associated with any of the Loan Documents and the transactions and events (including the enforcement or defense thereof) at any time associated therewith or 69 contemplated therein (including any violation or noncompliance with any Environmental Laws by any Related Person or any liabilities or duties of any Related Person or any Indemnified Party with respect to Hazardous Materials found in or released into the environment). THE FOREGOING INDEMNITIES SHALL EXTEND TO THE INDEMNIFIED PARTIES NOTWITHSTANDING THE SOLE OR CONCURRENT NEGLIGENCE OF EVERY KIND OR CHARACTER WHATSOEVER, WHETHER ACTIVE OR PASSIVE, WHETHER AN AFFIRMATIVE ACT OR AN OMISSION, INCLUDING ALL TYPES OF NEGLIGENT CONDUCT IDENTIFIED IN THE RESTATEMENT (SECOND) OF TORTS, OF ONE OR MORE OF THE INDEMNIFIED PARTIES OR BY REASON OF STRICT LIABILITY IMPOSED WITHOUT FAULT ON ONE OR MORE OF THE INDEMNIFIED PARTIES, unless and only to the extent that it shall be judicially determined (including without limitation by agreed alternative dispute resolution) that such liabilities and costs were proximately caused by the gross negligence or willful misconduct of any Indemnified Party, in which event the foregoing indemnities (a) shall continue for the benefit of the other Indemnified Parties in all respects, and (b) shall also continue for the benefit of such Indemnified Party but shall only extend to those portions of the liabilities and costs that are not determined to have been proximately caused by the gross negligence or willful misconduct of such Indemnified Party. Section 8.5. Rights as Lender. In its capacity as a Lender, Administrative Agent shall have the same rights and obligations as any Lender and may exercise such rights as though it were not Administrative Agent. Administrative Agent may accept deposits from, lend money to, act as Trustee under indentures of, and generally engage in any kind of business with any of the Related Persons or their Affiliates, all as if it were not Administrative Agent hereunder and without any duty to account therefor to any other Lender. Section 8.6. Sharing of Set-Offs and Other Payments. Each of Administrative Agent and Lender agrees that if it shall, whether through the exercise of rights under security documents or rights of banker's lien, set off, or counterclaim against Borrower or otherwise, obtain payment of a portion of the aggregate Obligations owed to it which, taking into account all distributions made by Administrative Agent under Section 2.9, causes Administrative Agent or such Lender to have received more than it would have received had such payment been received by Administrative Agent and distributed pursuant to Section 2.9, then (a) it shall be deemed to have simultaneously purchased and shall be obligated to purchase interests in the Obligations as necessary to cause Administrative Agent and all Lenders to share all payments as provided for in Section 2.9, and (b) such other adjustments shall be made from time to time as shall be equitable to ensure that Administrative Agent and all Lenders share all payments of Obligations as provided in Section 2.9; provided, however, that nothing herein contained shall in any way affect the right of Administrative Agent or any Lender to obtain payment (whether by exercise of rights of banker's lien, set- off or counterclaim or otherwise) of indebtedness other than the Obligations. Borrower expressly consents to the foregoing arrangements and agrees that any holder of any 70 such interest or other participation in the Obligations, whether or not acquired pursuant to the foregoing arrangements, may to the fullest extent permitted by law exercise any and all rights of banker's lien, set-off, or counterclaim as fully as if such holder were a holder of the Obligations in the amount of such interest or other participation. If all or any part of any funds transferred pursuant to this section is thereafter recovered from the seller under this section which received the same, the purchase provided for in this section shall be deemed to have been rescinded to the extent of such recovery, together with interest, if any, if interest is required pursuant to court order to be paid on account of the possession of such funds prior to such recovery. Section 8.7. Investments. Whenever Administrative Agent in good faith determines that it is uncertain about how to distribute to Lenders any funds which it has received, or whenever Administrative Agent in good faith determines that there is any dispute among Lenders about how such funds should be distributed, Administrative Agent may choose to defer distribution of the funds which are the subject of such uncertainty or dispute. If Administrative Agent in good faith believes that the uncertainty or dispute will not be promptly resolved, or if Administrative Agent is otherwise required to invest funds pending distribution to Lenders, Administrative Agent shall invest such funds pending distribution; all interest on any such investment shall be distributed upon the distribution of such investment and in the same proportion and to the same Persons as such investment. All moneys received by Administrative Agent for distribution to Lenders (other than to the Person who is Administrative Agent in its separate capacity as a Lender) shall be held by Administrative Agent pending such distribution solely as Administrative Agent for such Lenders, and Administrative Agent shall have no equitable title to any portion thereof. Section 8.8. Benefit of Article VIII. The provisions of this Article (other than the following Section 8.9) are intended solely for the benefit of Administrative Agent and Lenders, and no Related Person shall be entitled to rely on any such provision or assert any such provision in a claim or defense against Administrative Agent or any Lender. Administrative Agent and Majority Lenders may waive or amend such provisions (other than the following Section 8.9) as they desire without any notice to or consent of Borrower or any Related Person. Section 8.9. Resignation. Administrative Agent may resign at any time by giving written notice thereof to Lenders and Borrower, which notice shall set forth the date of such resignation. Administrative Agent may be removed at any time, with or without cause, by action of Majority Lenders. Upon any such resignation or removal, Borrower may, with the written concurrence of Majority Lenders, designate a successor Administrative Agent. If within fifteen days after the date of such resignation or removal Borrower makes no such designation or such written concurrence is not given, Majority Lenders shall have the right to appoint a successor Administrative Agent. A successor must be appointed for any retiring or removed Administrative Agent, and such Administrative Agent's resignation or removal shall become effective when such successor accepts such appointment. If, within thirty days after the date of the Administrative Agent's resignation or removal, no successor Administrative Agent has been appointed and has accepted such appointment, then the retiring or removed Administrative Agent may appoint a successor Administrative Agent, which shall be a commercial bank organized or licensed to conduct a banking or trust business under the laws of the United States of America or of any state thereof. Upon the acceptance of any appointment as Administrative Agent hereunder 71 by a successor Administrative Agent, the retiring or removed Administrative Agent shall be discharged from its duties and obligations under this Agreement and the other Loan Documents. After any resignation or removal of an Administrative Agent hereunder, the provisions of this Article VIII shall continue to inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under the Loan Documents. ARTICLE IX - Miscellaneous Section 9.1. Waivers and Amendments; Acknowledgments. (a) Waivers and Amendments. No failure or delay (whether by course of conduct or otherwise) by Administrative Agent or any Lender in exercising any right, power or remedy which Administrative Agent or such Lender may have under any of the Loan Documents shall operate as a waiver thereof or of any other right, power or remedy, nor shall any single or partial exercise by Administrative Agent or such Lender of any such right, power or remedy preclude any other or further exercise thereof or of any other right, power or remedy. No waiver of any provision of any Loan Document and no consent to any departure therefrom shall ever be effective unless it is in writing and signed as provided below in this section, and then such waiver or consent shall be effective only in the specific instances and for the purposes for which given and to the extent specified in such writing. No notice to or demand on any Related Person shall in any case of itself entitle any Related Person to any other or further notice or demand in similar or other circumstances. No waiver, consent, release, modification or amendment of or supplement to this Agreement or the other Loan Documents shall be valid or effective against any party hereto unless the same is in writing and signed by (i) if such party is Borrower, by Borrower, (ii) if such party is Administrative Agent, by Administrative Agent and (iii) if such party is a Lender, by such Lender or by Administrative Agent on behalf of Lenders with the written consent of Majority Lenders (which consent has already been given as provided in Section 9.7). Notwithstanding the foregoing or anything to the contrary herein, Administrative Agent shall not, without the prior consent of each individual Lender affected thereby, execute and deliver on behalf of such Lender any waiver or amendment which would: (1) waive any of the conditions specified in Article III (provided that Administrative Agent may in its discretion withdraw any request it has made under Section 3.2(f)), (2) increase any Lender's commitment to make Advances to any amount greater than its Percentage Share of $400,000,000, (3) reduce any fees hereunder, or the principal of, or interest on, such Lender's Note, (4) postpone any date fixed for any payment of any fees hereunder, or principal of, or interest on, such Lender's Note, (5) amend the definition herein of "Majority Lenders" or "Supermajority Lenders", or otherwise change the aggregate amount of Percentage Shares which is required for Administrative Agent, Lenders or any of them to take any particular action under the Loan Documents, or amend this Section 9.1(a), (6) release Borrower from its obligation to pay such Lender's Note or (except as provided in Section 6.8) release any Subsidiary Guarantor from its guaranty of such payment, or (7) release any Collateral, except such releases relating to sales of property as permitted under Section 5.2(f). (b) Acknowledgments and Admissions. Borrower hereby represents, warrants, acknowledges and admits that (i) it has been advised by counsel in the negotiation, execution and delivery of the Loan Documents to which it is a party, (ii) neither Administrative Agent nor any 72 Lender has any fiduciary obligation toward Borrower with respect to any Loan Document or the transactions contemplated thereby, (iii) the relationship pursuant to the Loan Documents between Borrower, on one hand, and Administrative Agent and each Lender, on the other hand, is and shall be solely that of debtor and creditor, respectively, (iv) no partnership or joint venture exists with respect to the Loan Documents between any of Borrower, Administrative Agent and Lenders, (v) Administrative Agent is not Borrower's Administrative Agent, but Administrative Agent for Lenders, (vi) should an Event of Default or Default occur or exist Administrative Agent and each Lender will determine in its sole discretion and for its own reasons what remedies and actions it will or will not exercise or take at that time, (vii) and without limiting any of the foregoing, Borrower is not relying upon any representation or covenant by Administrative Agent or any Lender, or any representative thereof, and no such representation or covenant has been made, that Administrative Agent or any Lender will, at the time of an Event of Default or Default, or at any other time, waive, negotiate, discuss, or take or refrain from taking any action permitted under the Loan Documents with respect to any such Event of Default or Default or any other provision of the Loan Documents. (c) Integration. This Agreement and the other Loan Documents set forth the entire understanding between the parties hereto with respect to the transactions contemplated herein and therein and supersede all prior discussions and understandings, written or oral, with respect to the subject matter hereof and thereof, and there are no representations, warranties, covenants, undertakings or agreements by any of the parties hereto relating to the subject matter hereof except as expressly set out in this Agreement or in another Loan Document. THIS WRITTEN AGREEMENT AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES. Section 9.2. Survival of Agreements; Cumulative Nature. All of the Related Persons' various representations, warranties, covenants and agreements in the Loan Documents shall survive the execution and delivery of this Agreement and the other Loan Documents and the performance hereof and thereof, including the making or granting of the Loans and the delivery of the Notes and the other Loan Documents, and shall further survive until all of the Obligations are paid in full to Administrative Agent and Lenders and all of Administrative Agent's and Lenders' obligations to Borrower are terminated. All statements and agreements contained in any certificate or other instrument delivered by any Related Person to Administrative Agent or any Lender under any Loan Document shall be deemed representations and warranties by Borrower or agreements and covenants of Borrower under this Agreement. The representations, warranties, indemnities, and covenants made by the Related Persons in the Loan Documents, and the rights, powers, and privileges granted to Administrative Agent and Lenders in the Loan Documents, are cumulative, and, except for expressly specified waivers and consents, no Loan Document shall be construed in the context of another to diminish, nullify, or otherwise reduce 73 the benefit to Administrative Agent or any Lender of any such representation, warranty, indemnity, covenant, right, power or privilege. In particular and without limitation, no exception set out in this Agreement to any representation, warranty, indemnity, or covenant herein contained shall apply to any similar representation, warranty, indemnity, or covenant contained in any other Loan Document, and each such similar representation, warranty, indemnity, or covenant shall be subject only to those exceptions which are expressly made applicable to it by the terms of the various Loan Documents. Section 9.3. Notices. All notices, requests, consents, demands and other communications required or permitted under any Loan Document shall be in writing, unless otherwise specifically provided in such Loan Document (provided that Administrative Agent may give telephonic notices to Lenders), and shall be deemed sufficiently given or furnished if delivered by personal delivery, by telecopy, by delivery service with proof of delivery, or by registered or certified United States mail, postage prepaid, to Borrower and the Related Persons at the address of Borrower specified on the signature pages hereto and to Administrative Agent and the other Lenders at their addresses specified on the signature pages hereto (unless changed by similar notice in writing given by the particular Person whose address is to be changed). Any such notice or communication shall be deemed to have been given (a) in the case of personal delivery or delivery service, as of the date of delivery at the address provided herein, (b) in the case of telecopy, upon receipt, or (c) in the case of registered or certified United States mail, three days after deposit in the mail; provided, however, that no Request for Advances or Rate Election shall become effective until actually received by Administrative Agent. Section 9.4. Joint and Several Liability; Parties in Interest. All Obligations which are incurred by two or more Related Persons shall be their joint and several obligations and liabilities. All grants, rights, covenants and agreements contained in the Loan Documents shall bind and inure to the benefit of the parties thereto and their respective successors and assigns; provided, however, that no Related Person may assign or transfer any of its rights or delegate any of its duties or obligations under any Loan Document without the prior consent of all Lenders. Neither any Related Person nor any Affiliate of any Related Person shall directly or indirectly purchase or otherwise retire any Obligations owed to any Lender nor will any Lender knowingly accept any offer to do so, unless each Lender shall have received substantially the same offer with respect to the same Percentage Share of the Obligations owed to it. If any Related Person or any Affiliate of any Related Person at any time purchases some but less than all of the Obligations owed to Administrative Agent and all Lenders, such purchaser shall not be entitled to any rights under the Loan Documents unless and until such Persons and their Affiliates have purchased all of the Obligations. (b) No Lender shall sell any participation interest in its commitment to make Advances or any of its rights under its Loan or under the Loan Documents to any Person other than an Eligible Transferee, and then only if the agreement between such Lender and such participant at all times provides: (i) that such participation exists only as a result of the agreement between such participant and such Lender and that such transfer does not give such participant any right 74 to vote as a Lender or any other direct claims or rights against any Person other than such Lender, (ii) that such participant is not entitled to payment from any Related Person under Sections 2.13 through 2.17 of amounts in excess of those payable to such Lender under such sections (determined without regard to the sale of such participation), and (iii) unless such participant is an Affiliate of such Lender, that such participant shall not be entitled to require such Lender to take any action under any Loan Document or to obtain the consent of such participant prior to taking any action under any Loan Document, except for actions which would require the consent of all Lenders under subsection (a) of Section 9.1. No Lender selling such a participation shall, as between the other parties hereto and such Lender, be relieved of any of its obligations hereunder as a result of the sale of such participation. Each Lender which sells any such participation to any Person (other than an Affiliate of such Lender) shall give prompt notice thereof to Administrative Agent and Borrower. (c) Except for sales of participations under the immediately preceding subsection (b), no Lender shall make any assignment or transfer of any kind of its commitment to make Advances or any of its rights under its Loan or under the Loan Documents, except for assignments to an Eligible Transferee, and then only if such assignment is made in accordance with the following requirements: (i) Each such assignment: (1) shall apply to all Obligations owing to the assignor Lender under this Agreement and to the unused portion of the assignor Lender's commitment to make Advances, so that after such assignment is made the assignor Lender shall have a fixed (and not a varying) Percentage Share (which shall be zero percent (0%) in the case of a total assignment) and be committed to make that Percentage Share of all future Advances and the assignee shall have a fixed (and not a varying) Percentage Share and be committed to make that Percentage Share of all future Advances, and (2) shall be in such an amount that, after such assignment is made, neither the assignor Lender nor the assignee will have interests in Loans and Notes under this Agreement which, together with their respective unused commitments to make Advances (and any other Loans which may be held by them hereunder), will be less than $15,000,000 in the aggregate (provided that such $15,000,000 limit shall not apply to any assignment made during the existence of any Event of Default). (ii) The parties to each such assignment shall execute and deliver to Administrative Agent, for its acceptance and recording in the "Register" (as defined below in this section), an Assignment and Acceptance in the form of Exhibit F, 75 appropriately completed, together with the Note subject to such assignment and a processing fee payable to Administrative Agent of $3500. Upon such execution, delivery, and payment and upon the satisfaction of the conditions set out in such Assignment and Acceptance, then (1) Borrower shall issue new Notes to such assignor (if appropriate) and assignee, and (2) as of the "Settlement Date" specified in such Assignment and Acceptance the assignee thereunder shall be a party hereto and a Lender hereunder and Administrative Agent shall thereupon deliver to Borrower and each Lender a schedule showing the revised Percentage Shares of such assignor Lender and such assignee Lender and the Percentage Shares of all other Lenders. (iii) Each assignee Lender which is not a United States person (as such term is defined in Section 7701(a)(30) of the Internal Revenue Code of 1986, as amended) for Federal income tax purposes, shall (to the extent it has not already done so) provide Administrative Agent and Borrower with the "Prescribed Forms" referred to in Section 2.17(d). (d) Nothing contained in this section shall prevent or prohibit any Lender from assigning or pledging all or any portion of its Loan and Note to any Federal Reserve Bank as collateral security pursuant to Regulation A of the Board of Governors of the Federal Reserve System and any Operating Circular issued by such Federal Reserve Bank; provided that no such assignment or pledge shall relieve such Lender from its obligations hereunder. (e) By executing and delivering an Assignment and Acceptance, each assignee Lender thereunder will be confirming to and agreeing with Administrative Agent and each other Lender hereunder that such assignee understands and agrees to the terms of this Agreement, including Section 2.11 and Article VIII hereof. (f) Administrative Agent shall maintain a copy of each Assignment and Acceptance and a register for the recordation of the names and addresses of the Lenders and the commitment to make Advances of, and principal amount of the Loan owing to, each Lender from time to time (in this section called the "Register"). The entries in the Register shall be conclusive, in the absence of manifest error, and Borrower, Administrative Agent and Lenders may treat each person whose name is recorded in the Register as a Lender hereunder for all purposes. The Register shall be available for inspection by Borrower or any Lender at any reasonable time and from time to time upon reasonable prior notice. Section 9.5. Governing Law; Submission to Process. Except to the extent that the law of another jurisdiction is expressly elected in a Loan Document, the Loan Documents shall be deemed contracts and instruments made under the laws of the State of Texas and shall be construed and enforced in accordance with and governed by the laws of the State of Texas and the laws of the United States of America, without regard to principles of conflicts of law. Chapter 346 of the Texas Finance Code, as amended (formerly Chapter 15 of Texas Revised Civil Statutes Annotated Article 5069) (which regulates certain revolving credit loan accounts and revolving tri-party accounts) does not apply to this Agreement or to the Notes. Borrower hereby irrevocably submits itself and each other Related Person to the non-exclusive jurisdiction of the state and federal courts sitting in the State of Texas and agrees and consents that service of 76 process may be made upon it or any of the Related Persons in any legal proceeding relating to the Loan Documents or the Obligations by any means allowed under Texas or federal law. Section 9.6. Limitation on Interest. Administrative Agent, Lenders, the Related Persons and any other parties to the Loan Documents intend to comply strictly with applicable usury law from time to time in effect. In furtherance thereof such Persons stipulate and agree that none of the terms and provisions contained in the Loan Documents shall ever be construed to create a contract to pay, for the use, forbearance or detention of money, interest in excess of the maximum amount of interest permitted by applicable law from time to time in effect. Neither any Related Person nor any present or future guarantors, indorsers, or other Persons hereafter becoming liable for payment of any Obligation shall ever be liable for unearned interest thereon or shall ever be required to pay interest thereon in excess of the maximum amount permitted by applicable law from time to time in effect, and the provisions of this section shall control over all other provisions of the Loan Documents which may be in conflict or apparent conflict herewith. Administrative Agent and Lenders expressly disavow any intention to contract for, receive, charge or collect excessive unearned interest or finance charges in the event the maturity of any Obligation is accelerated or any Obligation is prepaid. If (a) the maturity of any Obligation is accelerated for any reason, (b) any Obligation is prepaid and as a result any amounts held to constitute interest are determined to be in excess of the maximum amount permitted by applicable law then in effect, or (c) Administrative Agent or any Lender or any other holder of any or all of the Obligations shall otherwise collect moneys which are determined to constitute interest which would otherwise increase the interest on any or all of the Obligations to an amount in excess of that permitted by applicable law then in effect, then all sums determined to constitute interest in excess of the maximum amount then permitted by applicable law shall, without penalty, be promptly applied to reduce the then outstanding principal of the related Obligations or, if all Obligations have been paid in full or if Administrative Agent or such Lender or holder otherwise prefers, promptly returned to Borrower or the other payor thereof upon such determination. In determining whether or not the interest paid or payable, under any specific circumstance, exceeds the maximum amount permitted under applicable law, Administrative Agent, Lenders and the Related Persons (and any other payors thereof) shall to the greatest extent permitted under applicable law, (i) characterize any non-principal payment as an expense, fee or premium rather than as interest, (ii) exclude voluntary prepayments and the effects thereof, and (iii) amortize, prorate, allocate, and spread the total amount of interest throughout the entire contemplated term of the instruments evidencing the Obligations in accordance with the amounts outstanding from time to time thereunder and the maximum lawful rate of interest from time to time in effect under applicable law. In the event applicable law provides for an interest ceiling under Chapter 303 of the Texas Finance Code (the "Texas Finance Code") and Chapter 1D of Title 79, Tex. Rev. Civ. Stats. 1925 ("Chapter 1D") as amended, respectively for that day, the ceiling shall be the "indicated rate ceiling" or "weekly ceiling" as defined in the Texas Finance Code and Chapter 1D and shall be used when appropriate in determining the Highest Lawful Rate. As used in this section the term "applicable law" means the laws of the State of Texas or the laws of the United States of America, whichever laws allow the greater interest, as such laws now exist or may be changed or amended or come into effect in the future. Section 9.7. Termination; Limited Survival. In its sole and absolute discretion Borrower may at any time that no Obligations are owing elect in a written notice delivered to 77 Administrative Agent to terminate this Agreement. Upon receipt by Administrative Agent of such a notice, if no Obligations are then owing this Agreement and all other Loan Documents shall thereupon be terminated and the parties thereto released from all prospective obligations thereunder. Notwithstanding the foregoing or anything herein to the contrary, any waivers or admissions made by any Related Person in any Loan Document, any Obligations under Sections 2.13 through 2.17, and any obligations which any Person may have to indemnify or compensate Administrative Agent or any Lender shall survive any termination of this Agreement or any other Loan Document. At the request and expense of Borrower, Administrative Agent shall prepare and execute all necessary instruments to reflect and effect such termination of the Loan Documents. Administrative Agent is hereby authorized to execute all such instruments on behalf of all Lenders, without the joinder of or further action by any Lender. Section 9.8. Severability. If any term or provision of any Loan Document shall be determined to be illegal or unenforceable all other terms and provisions of the Loan Documents shall nevertheless remain effective and shall be enforced to the fullest extent permitted by applicable law. Section 9.9. Counterparts. This Agreement may be separately executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to constitute one and the same Agreement. SECTION 9.10. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY KNOWINGLY, VOLUNTARILY, INTENTIONALLY, AND IRREVOCABLY WAIVES, TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR DIRECTLY OR INDIRECTLY AT ANY TIME ARISING OUT OF, UNDER OR IN CONNECTION WITH THE LOAN DOCUMENTS, BEFORE OR AFTER MATURITY; CERTIFIES THAT NO PARTY HERETO NOR ANY REPRESENTATIVE OR AGENT OR COUNSEL FOR ANY PARTY HERETO HAS REPRESENTED, EXPRESSLY OR OTHERWISE, OR IMPLIED THAT SUCH PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, AND ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT, THE OTHER LOAN DOCUMENTS AND THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS CONTAINED IN THIS SECTION. Section 9.11. Restatement. Borrower has heretofore been indebted to Lenders under the Original Agreement. Upon the execution and delivery of this Agreement by each of the parties hereto: (a) any loans made under the Original Agreement and outstanding as of the date hereof shall be deemed Loans made hereunder as of the date hereof and shall be deemed made under, and evidenced by, the Notes and subject to the terms and conditions hereof and thereof, (b) the "Base Rate Portion" (as defined in the Original Agreement) of any such outstanding loan shall constitute a Base Rate Portion hereunder, and (c) each "Fixed Rate Portion" and related "Interest Period" (as defined in the Original Agreement) of any such outstanding loan shall carryover and continue as a Fixed Rate Portion hereunder, with an Interest Period ending on the last day of such 78 related "Interest Period", and in no event shall such carrying over and continuing of such Fixed Rate Portions (i) constitute a payment or prepayment of all or a portion of any "Fixed Rate Portion" or (ii) entitle any Lender to any reimbursement under Section 2.16 of the Original Agreement or Section 2.16 hereof with respect thereto. This Agreement amends and restates the Original Agreement in its entirety, and upon the effectiveness hereto, all terms and provisions hereof shall supersede the terms and provisions thereof. 79 IN WITNESS WHEREOF, this Agreement is executed as of the date first written above.

This Note (a) is issued and delivered under that certain Second Restated Credit Agreement dated June 30, 1999 among Borrower, certain of its Subsidiaries from time to time a party thereto, NationsBank, N.A., as Administrative Agent, and the financial institutions (including Lender) referred to therein (herein, as from time to time supplemented, amended or restated, called the "Credit Agreement"), and is a "Note" as defined therein, and (b) is subject to the terms and provisions of the Credit Agreement, which contains provisions for payments and prepayments hereunder and acceleration of the maturity hereof upon the happening of certain stated events. Payments on this Note shall be made and applied as provided herein and in the Credit Agreement. Reference is hereby made to the Credit Agreement for a description of certain rights, limitations of rights, obligations and duties of the parties hereto and for the meanings assigned to terms used and not defined herein. For the purposes of this Note, the following terms have the meanings assigned to them below: "Base Rate Payment Date" means (i) the last day of each March, June, September and December, beginning June 30, 1999, and (ii) any day on which past due interest or principal is owed hereunder and is unpaid. If the terms hereof or of the Credit Agreement provide that payments of interest or principal hereon shall be deferred from one Base Rate Payment Date to another day, such other day shall also be a Base Rate Payment Date. "Fixed Rate Payment Date" means, with respect to any Fixed Rate Portion: (i) the day on which the related Interest Period ends (and, if such Interest Period is three months or longer, the three-month anniversary of the first day of such Interest Period), and (ii) any day on which past due interest or past due principal is owed hereunder with respect to such Fixed Rate Portion and is unpaid. If the terms hereof or of the Credit Agreement 1 provide that payments of interest or principal with respect to such Fixed Rate Portion shall be deferred from one Fixed Rate Payment Date to another day, such other day shall also be a Fixed Rate Payment Date. Upon the occurrence of certain events as set forth in the Credit Agreement, all or a portion of the principal amount of this Note may be subject to mandatory prepayment. The principal amount of this Note, together with all interest accrued hereon, shall be due and payable in full on April 1, 2003. The Base Rate Portion of the Loan (exclusive of any past due principal or interest) from time to time outstanding shall bear interest on each day outstanding at the Base Rate in effect on such day. On each Base Rate Payment Date, Borrower shall pay to the holder hereof all unpaid interest which has accrued on the Base Rate Portion to but not including such Base Rate Payment Date. Each Fixed Rate Portion of the Loan (exclusive of any past due principal or interest) shall bear interest on each day during the related Interest Period at the related Fixed Rate in effect on such day. On each Fixed Rate Payment Date relating to such Fixed Rate Portion, Borrower shall pay to the holder hereof all unpaid interest which has accrued on such Fixed Rate Portion to but not including such Fixed Rate Payment Date. All past due principal of and past due interest on the Loan shall bear interest on each day outstanding at the Late Payment Rate in effect on such day, and such interest shall be due and payable daily as it accrues. Notwithstanding the foregoing provisions of this paragraph: (a) this Note shall never bear interest in excess of the Highest Lawful Rate, and (b) if at any time the rate at which interest is payable on this Note is limited by the Highest Lawful Rate (by the foregoing clause (a) or by reference to the Highest Lawful Rate in the definitions of Base Rate, Fixed Rate, and Late Payment Rate), this Note shall bear interest at the Highest Lawful Rate and shall continue to bear interest at the Highest Lawful Rate until such time as the total amount of interest accrued hereon equals (but does not exceed) the total amount of interest which would have accrued hereon had there been no Highest Lawful Rate applicable hereto. Notwithstanding the foregoing paragraph and all other provisions of this Note, in no event shall the interest payable hereon, whether before or after maturity, exceed the maximum amount of interest which, under applicable law, may be charged on this Note, and this Note is expressly made subject to the provisions of the Credit Agreement which more fully set out the limitations on how interest accrues hereon. In the event applicable law provides for an interest ceiling under Chapter303 of the Texas Finance Code (the "Texas Finance Code") and Chapter 1D of Title 79, Tex. Rev. Civ. Stats. 1925 ("Chapter 1D") as amended, respectively for that day, the ceiling shall be the "indicated rate ceiling" or "weekly ceiling" as defined in the Texas Finance Code and Chapter 1D and shall be used in this Note for calculating the Highest Lawful Rate and for all other purposes. The term "applicable law" as used in this Note shall mean the laws of the State of Texas or the laws of the United States, whichever laws allow the greater interest, as such laws now exist or may be changed or amended or come into effect in the future. If this Note is placed in the hands of an attorney for collection after default, or if all or any part of the indebtedness represented hereby is proved, established or collected in any court or in any bankruptcy, receivership, debtor relief, probate or other court proceedings, Borrower and all indorsers, sureties and guarantors of this Note jointly and severally agree to pay reasonable 2 attorneys' fees and collection costs to the holder hereof in addition to the principal and interest payable hereunder. Borrower and all indorsers, sureties and guarantors of this Note hereby severally waive demand, presentment, notice of demand and of dishonor and nonpayment of this Note, protest, notice of protest, notice of intention to accelerate the maturity of this Note, declaration or notice of acceleration of the maturity of this Note, diligence in collecting, the bringing of any suit against any party and any notice of or defense on account of any extensions, renewals, partial payments or changes in any manner of or in this Note or in any of its terms, provisions and covenants, or any releases or substitutions of any security, or any delay, indulgence or other act of any trustee or any holder hereof, whether before or after maturity. This Note and the rights and duties of the parties hereto shall be governed by the laws of the State of Texas (without regard to principles of conflicts of law), except to the extent the same are governed by applicable federal law.

Except as otherwise indicated herein, capitalized terms used in this opinion letter are defined as set forth in the Agreement. We have acted as counsel for Borrower in connection with the loan transactions provided for in the Agreement. As such counsel we have assisted in the negotiation of the Agreement and the other Loan Documents. We have examined executed counterparts (or, where indicated, photostatic copies of executed counterparts) of the documents listed in Annex II (attached hereto). (The documents listed in Annex II are hereinafter referred to as the "Principal Documents".) We have discussed the matters addressed in this opinion with officers and representatives of the Borrower to the extent we have deemed appropriate to enable us to render this opinion letter. In preparing this opinion letter we have also examined (subject to the qualification confirmed in lettered paragraph (c) below) original counterparts or photostatic or certified copies of all other instruments, agreements, certificates, records and other documents NationsBank, N.A., as Administrative Agent Morgan Guaranty Trust Company of New York, as Documentation Agent Each of the Lenders Named in Annex I June 30, 1999 Page 2 (whether of the borrower, its officers, directors, shareholders and representatives, public officials, or other persons) which we have considered relevant to the opinions hereinafter expressed. In making this examination we have assumed, with respect to all documents which we have examined: the genuineness of all signatures thereon, the authenticity of all documents submitted to us as originals, the conformity to the originals of all documents submitted to us as copies, the authenticity of the originals of such copies and the completeness of all such documents and copies. As to certain questions of fact material to such opinions we have, where such facts were not otherwise verified or established, relied upon the factual representations contained in the Agreement and the other Loan Documents and on the certificates attached hereto as Annex III made by officers of the Borrower. Based upon the foregoing, and subject to the qualifications and limitations hereinafter set forth, we are of the opinion that: 1. The Borrower is duly incorporated, validly existing and in good standing under the laws of the State of Delaware. 2. The Borrower has the corporate power and authority to execute and deliver each Principal Document and to perform its obligations thereunder. Each Principal Document has been duly authorized, executed and delivered by the Borrower. 3. Each Principal Document is enforceable against the Borrower. 4. The execution and delivery by the Borrower of the Principal Documents, and the consummation of the loan transactions contemplated by the Principal Documents, do not (a) violate any provision of the charter of bylaws of the Borrower, or (b) to our knowledge, breach or result in a default under or result in the maturing of any Indebtedness pursuant to any material agreement to which the Borrower is a party and which has been filed by the Borrower as an exhibit to any filing of the Borrower with the Securities and Exchange Commission, or (c) violate applicable provisions of statutory law or regulation or, to our knowledge, any material judgment, order, decree, determination or award of any court or governmental authority which is now in effect and applicable to the Borrower or any of its properties. 5. Except for any which have been obtained or completed, to our knowledge no consent, approval, waiver, license, authorization or action by or filing with any court or governmental authority is or was required for the execution and delivery by the Borrower of any of the Principal Documents, or the consummation of the loan transactions contemplated thereby (other than such filings and other actions as may be necessary to perfect the liens and security interests contemplated thereby). NationsBank, N.A., as Administrative Agent Morgan Guaranty Trust Company of New York, as Documentation Agent Each of the Lenders Named in Annex I June 30, 1999 Page 3 6. The Borrower is not subject to regulation under the Public Utility Holding Company Act of 1935, the Federal Power Act or the Investment Company Act of 1940 (as any of the preceding acts have been amended). 7. The Deed of Trust creates in favor of the Administrative Agent, for the ratable benefit of the Lenders, a security interest in all of the Borrower's right, title and interest in those items and types of Collateral described in the Deed of Trust in which a security interest may be created under Article 9 of the Uniform Commercial Code as in effect in the State of Texas (the "Texas UCC"). 8. The filing of the Texas Financing Statement in the Office of the Secretary of State of Texas will result in the perfection of the security interests (the "Texas Security Interests") in all Collateral (as such term is defined in the Deed of Trust) with respect to which (i) a security interest has been created under the Deed of Trust, (ii) perfection would, under the Texas UCC, be governed by the laws of the State of Texas, and (iii) a security interest may be perfected by the filing of a financing statement under the Texas UCC. 9. The acceptance of the Deed of Trust and the Texas Financing Statement by the Administrative Agent, its possession and retention of its rights thereunder and its presentation of the Texas Financing Statement for filing and recording as described in paragraph 8 hereof will not require the Administrative Agent or any Lender to pay or otherwise subject the Administrative Agent or any Lender to any Texas documentary, stamp or similar tax, fee or other charge, except the uniform fees prescribed under the Texas UCC. This opinion letter is limited by, subject to and based on the following: (a) This opinion is limited in all respects to the General Corporation Law of the State of Delaware, the laws of the State of Texas and applicable federal law. As you are aware, we are not members of the bar of the State of Delaware and our knowledge of the General Corporation Law of the State of Delaware is derived from a reading of those statutes without consideration of any judicial or administrative interpretations thereof. (b) In rendering this opinion we have assumed that each of the Principal Documents in which Administrative Agent's Documentation Agent's or any Lender's execution is provided for has been duly authorized, executed and delivered by such Person, and that each Lender is concurrently herewith advancing funds to Borrower or otherwise "giving value" as contemplated in Section 9.203 of the Code. (c) The qualification of any opinion or statement herein by the use of the words "to our knowledge" or "known to us" means that during the course of our representation as described in this opinion letter, no information has come to the attention of the attorneys in this firm involved in the loan transactions described which would give such attorneys current actual knowledge of the existence of the facts so qualified. We have not undertaken any review of court or other public records or other investigation to determine the existence of any facts or the accuracy or completeness of any representations, warranties, data or other information, written or oral, made or furnished to NationsBank, N.A., as Administrative Agent Morgan Guaranty Trust Company of New York, as Documentation Agent Each of the Lenders Named in Annex I June 30, 1999 Page 4 us or to you, and no inference as to our knowledge thereof shall be drawn from the fact of our representation of any party or otherwise. (d) Our opinion set forth in numbered paragraph 3 above is subject in all respects to the General Qualifications (i.e., the Bankruptcy and Insolvency Exception, the Equitable Principles Limitation and the Other Common Qualifications) as set forth, and as defined, in the Legal Opinion Accord (the "Accord") of the ABA Section of Business Law (1991). In addition to being subject to the General Qualifications as set forth in the Accord, our opinion as to the enforceability of the documents specified therein is subject to the further qualification that we give no opinion as to the enforceability of: (i) provisions restricting access to courts or to legal or equitable remedies or purporting to affect the jurisdiction or venue of courts; (ii) provisions purporting to establish evidentiary standards for suits or proceedings to enforce the Principal Documents; (iii) provisions purporting to waive rights to notice, legal defenses, statutes of limitations or other benefits that cannot be waived under applicable law; (iv) provisions granting powers of attorney or authority to execute documents or to act by power of attorney on behalf of the Borrower; (v) self-help remedies provided for in the documents; (vi) provisions providing that remedies are cumulative; (vii) provisions that decisions by a party are conclusive; (viii) provisions purporting to grant to or limit rights of third parties; (ix) provisions purporting to create a trust or constructive trust without compliance with applicable trust law; (x) provisions regarding contractual rights of set-off greater than such rights under applicable law; (xi) provisions purporting to impose restrictions on the alienation of property; and (xii) provisions purporting to establish standards for service of process in suits or proceedings to enforce the Principal Documents. (e) No opinion is expressed as to any usury savings provision in the Agreement or the other Loan Documents to the extent that it (i) purports to permit the cure of any violation of applicable usury laws by the rescission of any demand or charge, or the NationsBank, N.A., as Administrative Agent Morgan Guaranty Trust Company of New York, as Documentation Agent Each of the Lenders Named in Annex I June 30, 1999 Page 5 refunding,or the crediting against principal, of any interest that has been charged or received in violation of any applicable usury law or (ii) characterizes any non-principal payment as an expense, fee or premium rather than as interest or excludes voluntary prepayments and the effects thereof. (f) The opinions given herein as the creation and perfection of security interests do not cover real property or other property or transactions excluded from the coverage of the Texas UCC, nor timber to be cut, or minerals or the like or accounts subject to Subsection (e) of Section 9.103 of the Texas UCC or goods which are or are to become fixtures. (g) We express no opinion regarding the accuracy or completeness of any property descriptions contained in the Loan Documents, or the title to any assets pledged by the Borrower or the priority of any security interests created under the Loan Documents. (h) We express no opinion with respect to the enforceability of the Deed of Trust to the extent it purports to govern the creation, perfection or enforcement of any liens, security interests or other rights or remedies with respect to real property or related interests, including without limitation leases, fixtures and production and proceeds arising therefrom.

ANNEX III Officers' Certificates (see attached) EXHIBIT D-2 FORM OF OPINION OF CALIFORNIA COUNSEL FOR BORROWER 3 EXHIBIT D-2 [LETTERHEAD OF TIMOTHY J. LEWY APPEARS HERE] August 3, 1999 NationsBank, N.A., as Administrative Agent 700 Louisiana, 8th Floor Houston, Texas 77002 Attn: Energy Finance Division Re: Nuevo Energy Company Gentlemen: We have acted as counsel in the State of California for Nuevo Energy Company ("Borrower") in connection with the Security Documents (as defined below). All capitalized terms used and not defined herein shall have the same meanings as set forth in the Security Documents. We have examined executed copies of the following documents (the "Security Documents"): (1) Second Restated Credit Agreement, dated June 30, 1999, by and among Borrower, Administrative Agent and the Lenders named therein (the "Credit Agreement"). (2) Deed of Trust, Mortgage, Assignment, Security Agreement, Fixture Filing and Financing Statement, dated June 30, 1999, from Borrower to Marcia Bateman, Trustee, and NationsBank, N.A., Agent ("Administrative Agent") (the "Mortgage"). NationsBank, N.A. August 3, 1999 Page 2 (3) UCC-1 Financing Statement showing Borrower, as Debtor, and Administrative Agent, as Secured Party (the "Financing Statement"). Based upon the foregoing (and further subject to the qualifications and assumptions set forth below), we are of the opinion that: (1) The Security Documents constitute legal, valid and binding obligations of the Borrower, enforceable by the Administrative Agent, individually and as agent for the benefit of the Lenders, in accordance with their respective terms, to the extent that the laws of the State of California are applicable. (2) The forms of the Mortgage and the Financing Statement comply with all applicable laws and regulations of the State of California, including all applicable recording, filing and registration laws and regulations, and are adequate and legally sufficient under the laws and regulations of the State of California for the purposes intended to be accomplished thereby. (3) The Mortgage creates, to secure the indebtedness described in the Mortgage, a lien on the "Mortgaged Property" (as defined in the Mortgage) in favor of the Administrative Agent, individually and as agent for the ratable benefit of the Lenders, located in the State of California, and a security interest in the "Collateral" (as such term is defined in the Mortgage), and the proceeds of the "Collateral" in favor of the Administrative Agent, individually and as agent for the ratable benefit of the Lenders, with respect to which a security interest can be created under the California Uniform Commercial Code (the "Code"). (4) The following filings and recordations should be made: (A) A fully executed counterpart of the Mortgage, with the applicable portion of Exhibit "A" attached, is required to be recorded in the appropriate real property records of the Office of the County Recorder of each County in California in which all or any portion of the Mortgage Property is located; and NationsBank, N.A. August 3, 1999 Page 3 (B) A fully executed copy of the Financing Statement is required to be filed in the Office of the California Secretary of State and recorded in the appropriate real property records in the Office of the County Recorder of each County in California in which all or any portion of the Mortgaged Property is located. Once such Documents are filed and recorded, no further or subsequent filing or recording will be necessary in the State of California in order to perfect or continue the lien and security interest created by the Mortgage and the Financing Statement (or to continue the perfection of the lien and security interest created thereby which are covered by this Opinion), except that: (a) In the event that any of the indebtedness secured by the Mortgage has not been paid before ten (10) years after the stated maturity date of any Note described therein, then an extension agreement providing for the renewal and extension of such indebtedness should be entered into and recorded in the records of the County(s) where the Mortgage has been recorded; (b) A continuation statement with respect to the Financing Statement must be filed under the Code in the Office of the California Secretary of State within six (6) months prior to the expiration of five (5) years from the date of the original filing in such Office, and subsequent continuation statements must be filed within six (6) months prior to the end of each subsequent five (5) year period; and (c) Amendments or supplements to the Financing Statement and/or additional financing statements may be required to be filed in the event of the change of name, identity, or corporate structure of the Debtor, or in the event that the Financing Statement otherwise becomes inaccurate or incomplete. (5) The acceptance of the Security Documents by the Administrative Agent, the possession and retention of rights thereunder, and the presentation of such NationsBank, N.A. August 3, 1999 Page 4 instruments for filing and recording, as described in Paragraph 4 hereof, will not require the Administrative Agent or any Lender to pay, or otherwise subject the Administrative Agent or any Lender to, any tax, fee or other charge except the customary fee charged by each filing or recording officer on a per page or per instrument basis. Neither the Administrative Agent nor any Lender is required to qualify to do business in the State of California or otherwise to register or make any filing (other than those described in Paragraph 4 hereof) with any state or local official in the State of California solely as a result of the acceptance of such instruments, the possession and retention of rights thereunder, or the filing or recording thereof. The opinions expressed herein are subject to the following qualifications and assumptions: (1) This Opinion is limited to the laws of the State of California, and applicable federal law. We express no opinion as to the laws of any other jurisdiction. The Mortgage provides that it is to be governed by the laws of the State of Texas, except to the extent that the laws of another state where the Mortgaged Property (as defined in the Mortgage) is located necessarily, or appropriately, govern; we express no opinion as to such choice of Texas law, and have assumed, for purposes of this Opinion, that the Mortgage is to be interpreted and governed by the laws of the State of California. California securities laws are hereby expressly excepted from this Opinion. (2) We have considered the Security Documents solely from the point of view of their sufficiency under presently existing California law. This Opinion is intended to apply only to those presently existing facts, elements and consequences of such Documents, and to the transactions contemplated thereunder, as governed by presently existing California law. We undertake no responsibility for subsequent changes in any facts, elements or consequences of such Documents, or in any aspect of applicable law, including statutory and decisional law. (3) We have assumed that the Borrower and the Administrative Agent each are duly formed and validly existing, that the Borrower and the Administrative NationsBank, N.A. August 3, 1999 Page 5 Agent each has all requisite power and authority to enter into and perform its obligations under the Security Documents, and that the Borrower has duly authorized the execution and delivery, and has duly executed and delivered, the Security Documents. We have assumed that the Borrower is duly qualified to do business in the State of California, and is in good standing under all of the rules and regulations of the California Department of Corporations and the California Franchise Tax Board. (4) We have assumed that the Credit Agreement and the Notes are valid, binding and enforceable in accordance with their terms, and that loans have been or will be made to Borrower thereunder, which loans are intended to be secured by the Mortgage. (5) We have made no examination of, and express no opinion with respect to (i) the title to, or (except as to adequacy as to form) the descriptions of the properties described in the Mortgage, (ii) the priority of the liens created by the Mortgage or whether there are any other liens, security interests, charges or encumbrances on the properties described in the Mortgage, or (iii) whether the properties described in the Mortgage are the properties and interests intended to be covered thereby. (6) The obligations of Borrower under the Security Documents, and the availability of certain remedies provided for therein, may be affected by applicable bankruptcy, insolvency, moratorium, reorganization and other similar laws affecting creditors' rights generally (including, without limitation, applicable fraudulent transfer laws) and/or by general principles of equity including, without limitation, concepts of materiality, reasonableness, good faith and fair dealing (regardless of whether such enforceability is considered in a proceeding of equity or at law). Certain rights, remedies and waivers contained in the Security Documents may be limited or rendered ineffective by applicable laws governing such rights, remedies or waivers, and the exercise of certain rights, remedies or waivers contained in the Security Documents may affect the validity or enforceability of the Security Documents. Default, acceleration, termination and repossession under the Security Documents may all be subject to equitable supervision and, accordingly, may be based only upon material breaches. NationsBank, N.A. August 3, 1999 Page 6 However, in our view, the Security Documents contain adequate remedies, if properly invoked, for the practical realization of the security afforded thereby (except for the consequences of procedural delay that may result therefrom). (7) The obligations of Borrower under the Security Documents, and the availability of certain remedies provided for therein, may be affected by California's so-called "anti-deficiency" and "one action" statutes which appear to be fundamental state policies. Because the "anti-deficiency" and "one action" statutes have a long history in California of judicial protection, it is doubtful that the Administrative Agent or Lenders could avoid the fair value hearing requirements of California Code of Civil Procedure Sections 580a and 726 (if suit were brought in California for a deficiency judgment) or the one action requirements of Section 726 (if suit were brought in California directly on any Note secured by California real property, or if suit were brought in another state obtaining a personal money judgment against Borrower prior to the foreclosure of the California real property security), even if there is a foreign state choice of law provision in the Note or Security Documents and the foreign state permits deficiency judgments and direct actions on the Note, and even if the parties are domiciled in the foreign state and the Note is to be paid in the foreign state. On the basis of the foregoing, caution should be taken not to file an action or obtain a judgment in any state against the Borrower prior to the non-judicial foreclosure of the Mortgage in California. (8) Administrative Agent and Lenders should also be aware that Sections 2924 and 2924b of the California Civil Code provide that a power of sale contained in a deed of trust or mortgage may not be exercised until after the recordation of a notice of default (identifying the mortgage or deed of trust and stating, among other things, the nature of the default), and that within ten (10) days following recordation of the notice of default a copy of such notice must be delivered to each trustor or mortgagor and to each party who has previously recorded a request for such a copy. Section 2924c of the California Civil Code provides, in pertinent part, that whenever the maturity of an obligation secured by a deed of trust or mortgage is accelerated by reason of default in the payment of interest or of any installment of principal or other sum secured thereby, the trustor or mortgagor and certain other entitled persons have the right, at any NationsBank, N.A. August 3, 1999 Page 7 time within the period commencing with the date of recordation of the notice of default under such deed of trust and ending on the date that is five (5) business days prior to the date of foreclosure sale set forth in the initial recorded notice of sale, to cure such default by paying the entire amount then due (including certain reasonable costs and expenses incurred in enforcing such obligations, but excluding any amount that would not otherwise be due but for such acceleration) and thereby to reinstate such deed of trust or mortgage and the obligations secured thereby to the same effect as if no such acceleration had occurred. (9) We express no opinion with respect to any security interest in the Collateral, or the proceeds of the Collateral, other than the Collateral, or the proceeds of the Collateral, with respect to which a security interest can be created under the Code and perfected by the filing of a financing statement in the State of California. To the extent that any Security Document purports to create a security interest, we have assumed (without opining) that Borrower has rights in the applicable Collateral, that sufficient value has been given for the security interest, and that no agreement exists postponing attachment of the security interest. (10) In the case of proceeds of the Collateral, continuation or perfection of the security interest therein is limited to the extent set forth in Section 9-306 of the Code. (11) The definition of the Mortgaged Property in the Mortgage has been broadly drafted. The opinions expressed herein relating to the enforceability of the Mortgage and the creation of a mortgage lien with respect to the portion of the Mortgaged Property which is real property only apply to the interests of Borrower in and to leases and other interests described in Exhibit "A" to the Mortgage which Borrower had acquired prior to the execution of the Mortgage. We express no opinion with respect to any after acquired or other types of real property included in the description of the Mortgaged Property contained in the Mortgage. NationsBank, N.A. August 3, 1999 Page 8 (12) In the event that the Administrative Agent takes over the operation or control of any of the Mortgaged Property and/or any related Collateral in the State of California, pursuant to the Mortgage, or if the Mortgage is foreclosed, various filings and other acts may be required in the State of California in connection with the use or operation of such Mortgaged Properties and the related Collateral. The opinions expressed in Paragraph 5 above do not extend to any such filings or acts. This Opinion is solely for the benefit of the Administrative Agent and the Lenders, and may not be used or relied upon by any other person except the Administrative Agent and the Lenders, their successors and assigns, and by Thompson & Knight, P.C., counsel to Administrative Agent, without our express written consent. This Opinion is subject to future changes in applicable law. Very truly yours _______________________________________ TIMOTHY J.

EXHIBIT G SUPPLEMENT TO CREDIT AGREEMENT FOR ADDITIONAL SUBSIDIARY GUARANTOR THIS SUPPLEMENT TO CREDIT AGREEMENT (herein called this "Supplement") is executed as of _____________, _____ by ____________________, a _____________ (herein called "New Guarantor") for the benefit of NationsBank, N.A. , as Administrative Agent ("Administrative Agent"), Morgan Guaranty Trust Company of New York, as Documentation Agent ("Documentation Agent"), and each of the "Lenders" (as therein defined and herein so called) who are parties to that certain Second Restated Credit Agreement dated as of June 30, 1999 (as heretofore, now or hereafter amended, modified or supplemented, the "Credit Agreement") by and among Nuevo Energy Company, as Borrower (herein called "Borrower"), certain subsidiaries of Borrower from time to time a party thereto, as Subsidiary Guarantors, Administrative Agent, Documentation Agent, and Lenders. RECITALS: 1. The Credit Agreement contains various restrictions upon the ability of Borrower to make loans or other investments, but these restrictions generally do not apply to loans to or other investments in subsidiaries of Borrower which have become parties to the Credit Agreement as "Subsidiary Guarantors" (as therein defined and herein so called). 2. New Guarantor is a [wholly-owned // majority-owned] subsidiary of Borrower. New Guarantor desires to be able to receive such loans and investments to the maximum extent permitted under the Credit Agreement, and New Guarantor will require such loans and investments from time to time in order to carry out its business. The [board of directors] of New Guarantor has determined that New Guarantor's execution, delivery and performance of this Supplement, and its becoming a Subsidiary Guarantor pursuant hereto, may reasonably be expected to be of material benefit, direct and indirect, to New Guarantor and that the consummation of the transactions contemplated by this Supplement is in the best interests of New Guarantor. NOW, THEREFORE, in consideration of the premises and the mutual covenants and agreements contained herein and in the Credit Agreement, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and in order to induce Lenders to advance funds hereafter under the Credit Agreement, New Guarantor, Borrower, the other Subsidiary Guarantors, and Administrative Agent (on behalf of itself, Documentation Agent, and Lenders) hereby agree as follows: Section 1. Terms Defined in the Credit Agreement. Unless the context otherwise requires or unless otherwise expressly defined herein, the terms defined in the Credit Agreement shall have the same meanings whenever used in this Supplement. Section 2. Addition of New Guarantor as Party to Credit Agreement. New Guarantor is hereby added as a party to the Credit Agreement. Each reference to the term "Subsidiary Guarantor" or "Subsidiary Guarantors" in the Credit Agreement shall be deemed to include New Guarantor. New Guarantor hereby makes and confirms its irrevocable, absolute and unconditional guarantee, pursuant to Section 6.2 and the other provisions of Article VI of the Credit Agreement, of each Note, of all other sums payable under the Credit Agreement and the other Loan Documents, and of all obligations and undertakings of Borrower to Administrative Agent or Lenders under, by reason of, or pursuant to any of the Loan Documents.
