Based on such notices given to the Agent, which the Agent shall forward to the Borrower, the Borrower shall: (x) in the case of a Prepayment, prepay on the date specified in the Notice of Prepayment the Tranche B Loans of the Tranche B Lenders, if any, participating in such Prepayment and prepay the Prime Loans on such date or give a Notice of Borrowing with respect to a reborrowing of the Tranche A Loans due on such date such that the portion of such Prepayment which, together with all such prior Prepayments and Prospective Prepayments, does not exceed $20,000,000 shall, after giving effect to any repayment, prepayment and reborrowing of Loans on such day, assuming the conditions precedent set forth in Section 3.02 are met on such day, have been applied pro rata (based on the then outstanding amounts of the Loans) to the Loans of the Tranche B Lenders, if any, participating in such Prepayment and the Tranche A Lenders; or (y) in the case of a Prospective Prepayment, the Agent shall make such changes in the amounts of the scheduled installments due on the Tranche B Loans under Section 2.04(b) and the reductions of the Commitments under Section 2.06(c) scheduled to occur on the relevant Reduction Date, such that, after giving effect to any repayment, prepayment and reborrowing of Loans on such day, assuming the conditions precedent set forth in Section 3.02 are met on such day, the portion of such Prospective Prepayment which, together with all such prior Prepayments and Prospective Prepayments, does not exceed $20,000,000, shall have been applied pro rata (based on the then outstanding amounts of the Loans) to the Loans of the Tranche B Lenders, if any, participating in such Prospective Prepayment and the Tranche A Lenders. -29- (iii) In the case of any Prepayment or Prospective Prepayment, or a portion thereof, which, together with all prior Prepayments and Prospective Prepayments as to which notice has been given under this Section, exceeds $20,000,000, the Borrower shall: (x) in the case of a Prepayment, prepay on the date specified in the Notice of Prepayment the Tranche B Loans of the Tranche B Lenders and prepay the Prime Loans on such date or give a Notice of Borrowing with respect to a reborrowing of the Tranche A Loans due on such date such that the portion of such Prepayment which, together with all such prior Prepayments and Prospective Prepayments, exceeds $20,000,000 shall, after giving effect to any repayment, prepayment and reborrowing of Loans on such day, assuming the conditions precedent set forth in Section 3.02 are met on such day, have been applied pro rata (based on the then outstanding amounts of the Loans) to all of the Loans of the Lenders; or (y) in the case of a Prospective Prepayment, the Agent shall make such changes in the amounts of the scheduled installments due on the Tranche B Loans under Section 2.04(b) and the reductions of the Commitments under Section 2.06(c) scheduled to occur on the relevant Reduction Date, such that, after giving effect to any repayment, prepayment and reborrowing of Loans on such day, assuming the conditions precedent set forth in Section 3.02 are met on such day, the portion of such Prospective Prepayment which, together with all such prior Prepayments and Prospective Prepayments, exceeds $20,000,000, shall have been applied pro rata (based on the then outstanding amounts of the Loans) to all of the Loans of the Lenders. (d) Upon receipt of a Notice of Prepayment or Notice of Prospective Prepayment pursuant to this Section, the Agent shall promptly notify each Lender of the contents thereof, and such notice shall not thereafter be revocable by the Borrower. The Agent shall promptly advise each Lender of the portion of any Prepayment or Prospective Prepayment which is applicable to its Loan determined in accordance with subsection (c) above and shall also advise such Lender of the corresponding adjustments in the remaining scheduled reductions of such Loan under Section 2.04(b) or Section 2.06(c) and (d) as relevant. With respect to any prepayment of a -30- Tranche B Loan made as part of a Prepayment or as to the portion of any installment of a Tranche B Loan which is attributable to a Prospective Prepayment, the amount of each scheduled installment of such Loan which would have been required to be paid on a subsequent Reduction Date but for such Prepayment or Prospective Prepayment shall be for purposes of this Section 2.07 referred to as an "Eliminated Payment"; PROVIDED that the "Eliminated Payments" associated with any prepayment of a Tranche B Loan shall also include the reductions (if any) in Eliminated Payments occurring under subsection (e)(iii) below as a consequence of such prepayment. (e) (i) Any prepayment of Prime Loans or Tranche B Loans under subsection (c)(ii)(x) or subsection (c)(iii)(x) above shall be effected by payment by the Borrower to the Agent for the accounts of the relevant Lenders of the principal amount to be prepaid together with accrued interest thereon to the date of prepayment and, in the case of the portion of any Tranche B Loans prepaid pursuant to subsection (c)(iii)(x) above, an amount equal to the excess, if any, of (x) the net present value, at the time of such prepayment, of all future scheduled payments of principal and interest with respect to the corresponding Eliminated Payments, calculated as if such prepayment were not being made and using a discount rate equal to the yield, which shall be imputed by linear interpolation from the yields (as most recently published in Federal Reserve Statistical Release H.15 (519) or any successor publication thereto) of those United States Treasury notes which have maturities as close as practicable to the remaining weighted average life of such Eliminated Payments; OVER (y) the amount of such prepayment. (ii) If any portion of an installment of any Tranche B Loan due on a Reduction Date pursuant to Section 2.04(b) is payable due to a Prospective Prepayment (or portion thereof) described in subsection (c)(iii)(y) above, the Borrower shall also pay to the Agent for the account of the relevant Tranche B Lender an amount equal to the excess, if any, of (x) the net present value, at the time of such payment, of all future scheduled payments of principal and interest with respect to the corresponding Eliminated Payments, calculated as if such Prospective Prepayment (or portion thereof) had not occurred and using a discount rate equal to the yield, which shall be imputed by linear interpolation from the yields (as most recently published in Federal Reserve Statistical Release H.15 (519) or any successor publication thereto) of those United States Treasury notes which have maturities as close as practicable to the remaining weighted average life of such -31- Eliminated Payments; OVER (y) such portion of such installment. (iii) For purposes hereof, any reduction of a scheduled installment of a Tranche B Loan under Section 2.04 attributable to a prepayment of such Tranche B Loan under subsection (c)(iii)(x) shall be applied at the time of such prepayment first to reduce the portion, if any, of such installment which is then attributable to Prospective Prepayments described in subsection (c)(iii)(y) above and shall also reduce (on a pro rata basis, if there is more than one such Eliminated Payment) the corresponding Eliminated Payments associated with such portion of such installment. SECTION 2.08. GENERAL PROVISIONS AS TO PAYMENTS. The Borrower shall make each payment of principal of, and interest on, the Loans hereunder not later than 11:00 A.M. (New York City time) on the date when due, in Federal or other funds immediately available in New York City, to the Agent at its address referred to in Section 9.01. The Agent will wire transfer to each Lender, in accordance with the most recent wire transfer instructions previously delivered by such Lender to the Agent, the amount of each such payment received by the Agent for the account of such Lender. If such payment is received by the Agent at or before 11:00 A.M. (New York City time) on any date, such wire transfer shall be made by the Agent on such date. If such payment is received after 11:00 A.M. (New York City time), such wire transfer shall be made by the Agent on the next succeeding Domestic Business Day.

Whenever any payment of principal of, or interest on, the Euro-Dollar Loans shall be due on a day which is not a Euro-Dollar Business Day, the date for payment thereof shall be extended to the next succeeding Euro-Dollar Business Day unless such Euro-Dollar Business Day falls in another calendar month, in which case the date for payment thereof shall be the next preceding Euro-Dollar Business Day. If the date for any payment of principal is extended by operation of law or otherwise, interest thereon shall be payable for such extended time. SECTION 2.09. FUNDING LOSSES.

SECTION 2.10. COMPUTATION OF INTEREST AND FEES. Interest on Domestic Loans based on the Prime Rate shall be computed on the basis of a year of 365 days (or 366 days in a leap year) and paid for the actual number of days elapsed (including the first day but excluding the last day). Interest on Domestic Loans based on the Adjusted CD Rate and interest on Euro-Dollar Loans shall be computed on the basis of a year of 360 days and paid for the actual number of days elapsed, calculated as to each Interest Period or period fixed pursuant to Section 2.05(d) from and including the first day thereof to but excluding the last day thereof.

Any Tranche A Lender wishing to require payment of such additional interest (x) shall so notify the Borrower and the Agent, in which case such additional interest on the Euro-Dollar Loans of such Tranche A Lender shall be payable to such Tranche A Lender at the place indicated in such notice with respect to each Interest Period commencing at least five Domestic Business Days after the giving of such notice and (y) shall notify the Borrower at least five Domestic Business Days prior to each date on which interest is payable on the Tranche A Loans of the amount then due it under this Section. SECTION 2.12. INCREASE OF AGGREGATE LOANS. (a) The aggregate Commitments and Loans hereunder may from time to -33- time after the first Borrowing be increased by the addition of a new Lender and its commitment to this facility or by increasing the Commitment of any existing Lender under this facility, in the manner described in this Section. (b) At any time that the Borrower desires to increase the aggregate Commitments and Loans hereunder, it shall give notice thereof to the Agent, and shall specify whether it wishes such Commitments and Loans to be Tranche A Commitments and Loans or Tranche B Commitments and Loans or some combination thereof. In the case of any proposed increase in Tranche B Commitments and Loans hereunder, the Borrower shall, in such notice, state the interest rate per annum at which such Loans shall be made. The Agent shall promptly advise the Lenders of any such notice it receives from the Borrower. With respect to any proposed increase in Tranche A Commitments and Loans hereunder, each existing Tranche A Lender shall, within ten Domestic Business Days, advise the Agent as to whether it is willing to provide its share of such increase pro rata in proportion to the existing Commitments of the Tranche A Lenders. With respect to any proposed increase in Tranche B Commitments and Loans hereunder, each existing Tranche B Lender shall, within ten Domestic Business Days, advise the Agent as to whether it is willing to provide its share of such increase pro rata in proportion to the existing Commitments of the Tranche B Lenders. If any existing Tranche A or Tranche B Lenders hereunder are not willing to provide the full amounts of their shares of any such increase in the Commitments and Loans hereunder, the resulting shortfall shall be allocated among the remaining Tranche A or Tranche B Lenders, as relevant, as determined by the Borrower and the Agent, or the Borrower may designate one or more new Lenders, satisfactory to the Agent, to provide one or more new Commitments and Loans hereunder in the amount of such shortfall, and, in the case of Tranche B Loans, at the rate of interest per annum specified in the notice of the Borrower to the Agent described above. (e) The increase in existing Commitments or the addition of Commitments of new Lenders hereunder shall be effected by execution of an addendum to this Agreement as provided in Section 9.05. Simultaneously with the execution of such an addendum, the Borrower shall execute and deliver to the Agent a Euro-Dollar Note and a Domestic Note for each Lender that is a new Tranche A Lender, or a Tranche B Note for each Lender that is a Tranche B Lender making a new Loan under this Section, in each case dated the date of such addendum, and shall, in any case, execute and deliver such documents as the Agent may reasonably request relating to the authorization -34- for and validity of such addendum and, if relevant, such new Note or Notes. If the Borrower shall have provided security under Section 5.08 or 5.11, the documents relating to such security shall be amended as necessary or advisable to take account of the increased Commitments and Loans hereunder. (d) The Lender executing such addendum shall, not later than 11:00 A.M. (New York City time) on the date specified in such addendum, advance a Loan to the Borrower in an amount equal to, in the case of a new Lender, its Commitment, or, in the case of an existing Lender, the increase in its Commitment by making such amount available, in Federal or other funds immediately available in New York City, to the Agent at its address specified in or pursuant to Section 9.01. If such Loan is a Tranche A Loan, it shall be of the same type (Prime, CD or Euro-Dollar) as the then-outstanding Tranche A Loans and the Interest Period for such Tranche A Loan shall commence on such date and end on the last day of the then current Interest Period for the then-outstanding Tranche A Loans. Such Tranche A Loan shall mature, and the principal amount thereof be due and payable, on the last day of the Interest Period applicable thereto. If such Loan is a Tranche B Loan, the principal thereof shall be payable and interest thereon shall accrue and be payable as provided in Sections 2.04(b) and 2.05(e). (e) The borrowing of any Loan by the Borrower under this Section shall constitute a representation and warranty by the Borrower to all of the Lenders that: (i) immediately after such borrowing, no Default shall have occurred and be continuing; and (ii) the fact that the representations and warranties of the Borrower contained in this Agreement (except the representation and warranty set forth in Section 4.04(d) as to any material adverse change which has theretofore been disclosed in writing by the Borrower to the Lenders) are true on and as of the date of such borrowing. -35- ARTICLE III CONDITIONS TO BORROWINGS SECTION 3.01.

The Borrower will cause Hydrocarbons produced from the Petroleum Properties to be marketed in a commercially reasonable manner at commercially reasonable prices. The Borrower will have no Subsidiaries (i) except with the prior written consent of the Required Lenders, such consent not to be unreasonably withheld provided that the provisions of this Agreement are amended to take account thereof as deemed appropriate by the Required Lenders and (ii) except for Subsidiaries which may exist on a transitory basis not to exceed 90 days in the course of an acquisition by the Borrower of oil and gas properties by way of a purchase of stock or partnership interests.

SECTION 5.07. DEBT. The Borrower shall not incur any Debt on or after the date of this Agreement unless, immediately after such incurrence of Debt, (i) no Default shall have occurred and be continuing and (ii) the Life-of Reserves Coverage Ratio is equal to or greater than 1.75 and the Annual Coverage Ratio is equal to or greater than 1.20. -45- Furthermore, the Borrower shall not incur any Debt after a Triggering Event, or an event described in clause (II) or (III) of Section 5.11(a), has occurred until it has complied with Section 5.11(a) or such compliance is, pursuant to a waiver granted under Section 5.11(b) or pursuant to the provisions of Section 5.11(c), no longer required. For purposes of this Section, a Rollover shall not be deemed an incurrence of Debt. SECTION 5.08. COVERAGE RATIOS; SECURITY (a) If the Life-of-Reserves Coverage Ratio set forth in any certificate delivered pursuant to Section 5.01(c) or Coverage Report delivered pursuant to Section 5.01(i)(z) is less than 1.75, or if the Annual Coverage Ratio set forth in such certificate or Coverage Report is less than 1.20, then, within 60 days of the date of such report, the Borrower shall (i) reduce Debt, (ii) in accordance with Section 2.07(c), adjust the amounts of installments of Tranche B Loans under Section 2.04(b) and the amounts of mandatory reductions of Commitments under Section 2.06(c) so that amounts scheduled to be paid under such Sections are reduced for later Reduction Dates and increased (by an equal amount in aggregate) for earlier Reduction Dates or (iii) acquire additional Recognized Proved Reserves (acceptable to the Required Lenders and included in a supplement, prepared by an Independent Petroleum Engineer and delivered to the Lenders within such 60-day period, to the Most Recent Engineering Report) such that, based on a new Coverage Report delivered to the Lenders within such 60-day period, the Life-of-Reserves Coverage Ratio is equal to or greater than 1.75 and the Annual Coverage Ratio is equal to or greater than 1.20; PROVIDED that, if a Triggering Event, or an event described in clause (II) or (III) of Section 5.11(a), has occurred, the Life-of-Reserves Coverage Ratio shall not on any day be less than 1.90 unless the Borrower has complied with Section 5.11(a) or such compliance is, pursuant to a waiver granted under Section 5.11(b) or pursuant to the provisions of Section 5.11(c), no longer required.

(c) If the Borrower provides security pursuant to clause (b)(i) above, it shall at all times thereafter maintain a perfected first priority (except as aforesaid) lien for the benefit of the Lenders covering the lesser of (l) the Lenders' Pro Rata Share (as calculated from time to time) of 80% (in Relative Value) of the Petroleum Properties not subject to Liens described in Section 5.10(a) and (2) such Petroleum Properties (x) the Cash Flow Available for Debt Service from which for the period of twenty fiscal years commencing with the fiscal year in which the date of determination occurs equals or exceeds (y) 190% of the sum of the aggregate outstanding principal amount of the Loans and interest scheduled to accrue on the Loans (using the interest rates for the Loans as set forth in the most recent Approved Assumptions).

SECTION 7.06. INDEMNIFICATION. Each Lender shall, ratably in accordance with its outstanding Loans, indemnify the Agent (to the extent not reimbursed by the Borrower) against any cost, expense (including counsel fees and disbursements), claim, demand, action, loss or liability (except such as result from the Agent's gross negligence or willful misconduct) that the Agent may suffer or incur in connection with this Agreement or any action taken or omitted by the Agent hereunder. SECTION 7.07. CREDIT DECISION.

BASIS FOR DETERMINING INTEREST RATE INADEQUATE OR UNFAIR. If on or prior to the first day of any Interest Period: (a) the Agent is advised by the Reference Banks that deposits in dollars (in the applicable amounts) are not being offered to the Reference Banks in the relevant market for such Interest Period, or (b) Tranche A Lenders having 66 2/3% or more of the aggregate amount of the Tranche A Commitments advise the Agent that the Adjusted CD Rate or the London Interbank Offered Rate, as the case may be, as determined by the Agent will not adequately and fairly reflect the cost to such Tranche A Lenders of funding their Fixed Rate Loans for such Interest Period, the Agent shall forthwith give notice thereof to the Borrower and the Tranche A Lenders, whereupon until the Agent notifies the Borrower that the circumstances giving rise to such suspension no longer exist, the obligations of the Tranche A Lenders to make CD Loans or Euro-Dollar Loans, as the case may be, shall be suspended. Unless the Borrower notifies the Agent at least two Domestic Business Days before the date of any Fixed Rate Borrowing for which a Notice of Borrowing has previously been given that it elects not to borrow on such date, such Borrowing shall instead be made as a Prime Borrowing. SECTION 8.02. ILLEGALITY. If, after the date of this Agreement, the adoption of any applicable law, rule or regulation, or any change therein, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Tranche A Lender (or its Euro-Dollar Lending Office) with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency shall make it unlawful or impossible for any Tranche A Lender (or its Euro-Dollar Lending Office) to make, maintain or fund its Euro-Dollar Loans and such Tranche A Lender shall so notify the Agent, the Agent shall forthwith give notice thereof to -58- the other Tranche A Lenders and the Borrower, whereupon until such Tranche A Lender notifies the Borrower and the Agent that the circumstances giving rise to such suspension no longer exist, the obligation of such Tranche A Lender to make Euro-Dollar Loans shall be suspended. Before giving any notice to the Agent pursuant to this Section, such Tranche A Lender shall designate a different Euro-Dollar Lending Office if such designation will avoid the need for giving such notice and will not, in the judgment of such Tranche A Lender, be otherwise materially disadvantageous to such Tranche A Lender. If such Tranche A Lender shall determine that it may not lawfully continue to maintain and fund any of its outstanding Euro-Dollar Loans to maturity and shall so specify in such notice, the Borrower shall immediately prepay in full the then outstanding principal amount of each such Euro-Dollar Loan, together with accrued interest thereon. Concurrently with prepaying each such Euro-Dollar Loan, the Borrower shall borrow a Prime Loan in an equal principal amount from such Tranche A Lender (on which interest and principal shall be payable contemporaneously with the related Euro-Dollar Loans of the other Tranche A Lenders), and such Tranche A Lender shall make such a Prime Loan. SECTION 8.03. INCREASED COST AND REDUCED RETURN. (a) If after the date hereof, the adoption of any applicable law, rule or regulation, or any change therein, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Tranche A Lender (or its Lending Office) with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency: (i) shall subject any Tranche A Lender (or its Lending Office) to any tax, duty or other charge with respect to its Fixed Rate Loans, its Notes or its obligation to make Fixed Rate Loans, or shall change the basis of taxation of payments to any Tranche A Lender (or its Lending Office) of the principal of or interest on its Fixed Rate Loans or any other amounts due under this Agreement in respect of its Fixed Rate Loans or its obligation to make Fixed Rate Loans (except for changes with respect to tax on net income or any tax computed by reference to net income of such Tranche A Lender or its applicable Lending Office imposed by the jurisdiction in which such Tranche A Lender's principal executive office or applicable Lending Office is located); or -59- (ii) shall impose, modify or deem applicable any reserve, special deposit or similar requirement (including, without limitation, any such requirement imposed by the Board of Governors of the Federal Reserve System, but excluding (A) with respect to any CD Loan any such requirement included in an applicable Domestic Reserve Percentage and (B) with respect to any Euro-Dollar Loan any such requirement for which such Tranche A Lender is entitled to compensation during the relevant Interest Period pursuant to Section 2.11) against assets of, deposits with or for the account of, or credit extended by, any Tranche A Lender (or its Lending Office) or shall impose on any Tranche A Lender (or its Lending Office) or on the United States market for certificates of deposit or the London interbank market any other condition affecting its Fixed Rate Loans, its Notes or its obligation to make Fixed Rate Loans; and the result of any of the foregoing is to increase the cost to such Tranche A Lender (or its Lending Office) of making or maintaining any Fixed Rate Loan, or to reduce the amount of any sum received or receivable by such Tranche A Lender (or its Lending Office) under this Agreement or under its Notes with respect thereto, by an amount deemed by such Tranche A Lender to be material, such Tranche A Lender shall promptly after its determination of such occurrence give notice thereof to the Agent (which shall promptly give notice to the Borrower), and the Borrower shall pay to such Tranche A Lender from time to time, within 30 days of demand, such amount as such Tranche A Lender certifies to be the amount that will compensate it for such increased costs, provided that the Borrower's obligation to pay such Tranche A Lender shall be limited to the increased costs that are attributable to the period of time commencing with the date 30 days prior to the date on which such Tranche A Lender's notice is received by the Borrower. (b) If after the date hereof, any Tranche A Lender shall have determined that the adoption of any applicable law, rule or regulation regarding capital adequacy, or any change therein, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Tranche A Lender (or its Lending Office) with any request or directive regarding capital adequacy (whether or not having the force of law) -60- of any such authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on such Tranche A Lender's capital as a consequence of its obligations hereunder to a level below that which such Tranche A Lender could have achieved but for such adoption, change or compliance (taking into consideration such Tranche A Lender's policies with respect to capital adequacy) by an amount deemed by such Tranche A Lender to be material, such Tranche A Lender shall promptly after its determination of such occurrence give notice thereof to the Agent (which will promptly give notice to the Borrower), and the Borrower shall pay to such Tranche A Lender from time to time, within 30 days of demand, such amount as such Tranche A Lender certifies to be the amount that will compensate it for such reduction provided that the Borrower's obligation to pay such Tranche A Lender shall be limited to the reduction that is attributable to the period of time commencing with the date 30 days prior to the date on which such Tranche A Lender's notice is received by the Borrower. (c) Each Tranche A Lender will promptly notify the Borrower and the Agent of any event of which it has knowledge, occurring after the date hereof, which will entitle such Tranche A Lender to compensation pursuant to this Section and will designate a different Lending Office if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the judgment of such Tranche A Lender, be otherwise materially disadvantageous to such Tranche A Lender. A certificate of any Tranche A Lender claiming compensation under this Section and setting forth the additional amount or amounts to be paid to it hereunder shall be conclusive in the absence of manifest error. In determining such amount, such Tranche A Lender may use any reasonable averaging and attribution methods. SECTION 8.04. PRIME LOANS SUBSTITUTED FOR AFFECTED FIXED RATE LOANS. If (i) the obligation of any Tranche A Lender to make Euro-Dollar Loans has been suspended pursuant to Section 8.02 or (ii) any Tranche A Lender has demanded compensation under Section 8.03(a) and the Borrower shall, by at least five Euro-Dollar Business Days' prior notice to such Tranche A Lender through the Agent, have elected that the provisions of this Section shall apply to such Tranche A Lender, then, unless and until such Tranche A Lender notifies the Borrower that the circumstances giving rise to such suspension or demand for compensation no longer apply: (a) all Loans which would otherwise be made by such Tranche A Lender as CD Loans or Euro-Dollar -61- Loans, as the case may be, shall be made instead as Prime Loans (on which interest and principal shall be payable contemporaneously with the related Fixed Rate Loans of the other Tranche A Lenders), and (b) after each of its CD Loans or Euro-Dollar Loans, as the case may be, has been repaid, all payments of principal which would otherwise be applied to repay such Fixed Rate Loans shall be applied to repay its Prime Loans instead. SECTION 8.05. SUBSTITUTION OF LENDER. If (i) the obligation of any Tranche A Lender to make Euro-Dollar Loans has been suspended pursuant to Section 8.02 or (ii) any Tranche A Lender has demanded compensation under Section 8.03, the Borrower shall have the right, with the assistance of the Agent, to seek a mutually satisfactory (to the Borrower and the Agent) substitute lender or lenders (which may be one or more of the Lenders) to purchase the Notes and assume the Tranche A Commitment of such Tranche A Lender. ARTICLE IX MISCELLANEOUS SECTION 9.01. NOTICES. All notices, requests and other communications to any party hereunder shall be in writing (including bank wire, telex, telecopy or similar writing) and shall be given to such party at its address or telex or telecopy number set forth on the signature pages hereof or such other address or telex or telecopy number as such party may hereafter specify for the purpose by notice to the Agent and the Borrower. Each such notice, request or other communication shall be effective (i) if given by telex or telecopy, when such telex or telecopy is transmitted to the telex or telecopy number specified in this Section and, in the case of a telex, the appropriate answerback is received, (ii) if given by mail, 72 hours after such communication is deposited in the mails with first class postage prepaid, addressed as aforesaid or (iii) if given by any other means, when delivered at the address specified in this Section; PROVIDED that notices to the Agent under Article II and requests to the Lenders under Section 5.11(c)(ii) shall not be effective until received. -62- SECTION 9.02. NO WAIVERS. No failure or delay by the Agent or any Lender in exercising any right, power or privilege hereunder or under any Note or any Mortgage shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by law. SECTION 9.03. EXPENSES; DOCUMENTARY TAXES. The Borrower shall pay (i) all reasonable out-of-pocket expenses of the Agent, including reasonable fees and disbursements of special counsel for the Lenders and the Agent, in connection with the preparation of this Agreement, any waiver or consent hereunder or any amendment hereof or any Default or alleged Default hereunder, (ii) all out-of-pocket expenses of the Agent, including fees and disbursements of counsel for the Lenders and the Agent, in connection with the preparation, execution, recordation, or administration of any Mortgage and (iii) if an Event of Default occurs, all out-of-pocket expenses incurred by the Agent or any Lender, including fees and disbursements of counsel, in connection with such Event of Default and collection and other enforcement proceedings resulting therefrom. The Borrower shall indemnify each Lender against any transfer taxes, recording taxes, documentary taxes, assessments or charges made by any governmental authority by reason of the execution and delivery of this Agreement or the Notes or of the execution and recordation of any Mortgage. SECTION 9.04. SHARING OF SET-OFFS. Each Lender agrees that if it shall, by exercising any right of set-off or counterclaim or otherwise, receive payment of a proportion of the aggregate amount of principal and interest due with respect to any Note held by it which is greater than the proportion received by any other Lender in respect of the aggregate amount of principal and interest due with respect to any Note held by such other Lender, the Lender receiving such proportionately greater payment shall purchase such participations in the Notes held by the other Lenders, and such other adjustments shall be made, as may be required so that all such payments of principal and interest with respect to the Notes held by the Lenders shall be shared by the Lenders pro rata; PROVIDED that nothing in this Section shall impair the right of any Lender to exercise any right of set-off or counterclaim it may have and to apply the amount subject to such exercise to the payment of indebtedness of the Borrower other than its indebtedness under the Notes. The Borrower -63- agrees, to the fullest extent it may effectively do so under applicable law, that any holder of a participation in a Note, whether or not acquired pursuant to the foregoing arrangements, may exercise rights of set-off or counterclaim and other rights with respect to such participation as fully as if such holder of a participation were a direct creditor of the Borrower in the amount of such participation. SECTION 9.05. AMENDMENTS AND WAIVERS. Any provision of this Agreement or the Notes or the Mortgage may be amended or waived if, but only if, such amendment or waiver is in writing and is signed by the Borrower and the Required Lenders (and, if the rights or duties of the Agent are affected thereby, by the Agent); PROVIDED that no such amendment or waiver shall, unless signed by all the Lenders, (i) increase the Commitment of any Lender or subject any Lender to any additional obligation, except as contemplated by Section 2.12 and the further PROVISO below, (ii) reduce the principal of or rate of interest on any Loan or any fees hereunder, (iii) effect any amendment in the provisions of Section 2.07, 6.03, 6.04 or 9.04, (iv) effect any amendment in Section 5.08 or 5.11 or permit the release of any Mortgage except pursuant to a waiver granted under Section 5.11(b) or pursuant to the provisions of Section 5.12(b), (v) postpone the date fixed for any payment of principal of or interest on any Loan or any fees hereunder or (vi) change the percentage of the Commitments or of the aggregate unpaid principal amount of the Notes which shall be required for the Lenders or any of them to take any action under this Section or any other provision of this Agreement; PROVIDED FURTHER that the signature pages hereof may be amended to include a new Lender and to set forth its Commitment or to increase the Commitment of an existing Lender (as contemplated by Section 2.12) and to reflect the resulting increase in the aggregate Commitments by execution of an addendum hereto by the Borrower, the Agent and such Lender, and all references herein, or in any other document, to this Agreement shall thereafter be deemed to refer to this Agreement as amended by such addendum. The Agent shall promptly give notice to the Borrower and all Lenders of any amendment or waiver of this Agreement or the Notes or any Mortgage. SECTION 9.06. SUCCESSORS AND ASSIGNS. (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns, except that (i) the Borrower may not assign or otherwise transfer any of its rights under this Agreement and (ii) no Tranche A Lender may, without the prior written consent of the Borrower, assign any Tranche A Loan -64- hereunder; PROVIDED that nothing herein shall be deemed to prohibit the granting by any Tranche A Lender of participation in any Tranche A Loan hereunder or the sale, assignment, pledge or other transfer by any Tranche A Lender of its Notes and its rights thereunder to any Federal Reserve Bank. (b) The Agent and the Borrower may, for all purposes of this Agreement, treat any Lender as the holder of any Note drawn to it or its order (and owner of the Loans evidenced thereby) until written notice of assignment, participation or other transfer shall have been received by them and reflected on the Borrower's books; PROVIDED that no Tranche A Lender or participant shall give any such written notice with respect to any participation referred to in the PROVISO contained in subsection (a) prior to the occurrence of an Event of Default. The Borrower shall promptly record on its books all notices it receives under this subsection (b). In the case of any transfer of a Tranche B Note, the Borrower shall execute and deliver a new Tranche B Note payable to the transferee upon surrender of the old Tranche B Note duly endorsed or accompanied by a written instrument of transfer duly executed by the registered holder of the old Tranche B Note. Such new Tranche B Note shall be dated and bear interest from the date to which interest has been paid on the surrendered Tranche B Note or from the date of the surrendered Note if no interest has been paid thereon. (c) No assignee, participant or other transferee of any Tranche A Lender's rights shall be entitled to receive any greater payment under Section 8.03 than such Lender would have been entitled to receive with respect to the rights transferred, except in the case of an assignment made with the Borrower's prior written consent or by reason of the provisions of Section 8.02 or 8.03 requiring such Lender to designate a different Lending Office under certain circumstances or at a time when the circumstances giving rise to such greater payment did not exist. (d) If any Reference Bank assigns its Notes to an unaffiliated institution, the Agent shall, in consultation with the Borrower and with the consent of the Tranche A Lenders, appoint another bank to act as a Reference Bank hereunder. SECTION 9.07. COLLATERAL. Each of the Lenders represents to the Agent and each of the other Lenders that it in good faith is not relying upon any "margin stock" (as defined in Regulation G and Regulation U) as collateral in the -65- extension or maintenance of the credit provided for in this Agreement. SECTION 9.08. REPRESENTATIONS OF LENDERS. Each Tranche A Lender represents that it is making its Loan in the ordinary course of its commercial banking business and not with a view toward distribution thereof, and each Tranche B Lender represents that it is acquiring its Tranche B Note for investment for its own account and not with a view toward distribution thereof, subject, nevertheless, to any requirement of law that the disposition of its property shall at all times be within its control. SECTION 9.09. CONFIDENTIALITY. Any information which any of the Lenders receives from the Borrower which is designated proprietary or confidential at the time of receipt thereof by such Lender shall not be disclosed by such Lender to any other Person, if such information is not otherwise in the public domain, other than (i) to its independent accountants and legal counsel, (ii) pursuant to statutory and regulatory requirements, (iii) pursuant to any mandatory court order, or (iv) to any other Lender or, subject to an agreement containing provisions substantially the same as those of this Section, to any participant in or assignee of, or prospective participant in or assignee of, any Loan. SECTION 9.10. NEW YORK LAW. This Agreement and each Note shall be construed in accordance with and governed by the law of the State of New York. SECTION 9.11. COUNTERPARTS; EFFECTIVENESS. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement shall become effective when the Agent shall have received counterparts hereof signed by all of the parties hereto. SECTION 9.12. NON-RECOURSE TO PARTNERS. No recourse shall be had for the payment of the principal of or interest on any Loan, or for any claim based thereon, or otherwise in respect thereof, or with respect to any other obligation hereunder, against any past, present or future partner of the Borrower or any partner thereof (including, without limitation, Santa Fe Pacific Exploration and Santa Fe Energy), and in no event shall any such Person be held liable, personally or otherwise with respect to the indebtedness evidenced by the Notes or for any obligations under this Agreement, whether by virtue of any statute or rule of law, or -66- by the enforcement of any assessment or penalty or otherwise, all such liability being expressly waived and released by the Agent and each Lender. IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed by their respective authorized officers as of the day and year first above written.
