(c) If Lenders constituting at least the Required Lenders approve the extension of the then scheduled Termination Date and if one (1) or more of the Lenders shall notify, or be deemed to notify, the Administrative Agent pursuant to clause (a) of this Section 2.2 that it will not extend the then scheduled Termination Date (such Lenders herein called the "Declining Lenders"), then (A) the Administrative Agent shall promptly so notify the Company and the Accepting Lenders, (B) the Accepting Lenders shall, upon the Company's election to extend the then scheduled Termination Date in accordance with clause (i) or (ii) below, extend the then scheduled Termination Date and (C) the Company shall pursuant to a notice delivered to the Administrative Agent, the Accepting Lenders and the Declining Lenders, no later than the fifth day following the date by which each Lender is required, pursuant to Section 2.2(a), to approve or disapprove the requested extension of the Aggregate Commitment, either: (i) elect to extend the Termination Date with respect to the Accepting Lenders and direct the Declining Lenders to terminate their Commitments, which termination shall become effective on the date which would have been the Termination Date except for the operation of this Section 2.2. On such date, (x) the Company shall deliver a notice of the effectiveness of such termination to the Declining Lenders with a copy to the Administrative Agent and (y) the Company shall pay in full in immediately available funds all Obligations of the Company owing to the Declining Lenders and (z) upon the occurrence of the events set forth in clauses (x) and (y), the Declining Lenders shall each cease to be a Lender hereunder for all purposes, other than for purposes of Section 14.7, and shall cease to have any obligations or any Commitment hereunder, other than to the Agents pursuant to Section 15.8 and the Administrative Agent shall promptly notify the Accepting Lenders and the Company of the new Aggregate Commitment; or (ii) elect to extend the Termination Date with respect to the Accepting Lenders and, prior to or no later than the then scheduled Termination Date, (A) to replace one or more of the Declining Lender or Lenders with another lender or lenders reasonably acceptable to the Administrative Agent (such lenders herein called the "Replacement Lenders") and (B) the Company shall pay in full in immediately available funds all Obligations of the Company owing to the Declining Lenders which are not being replaced, as provided in clause (i) above; provided that (x) the Replacement Lender or Lenders shall purchase, and the Declining Lender or Lenders shall sell, the Notes of the Declining Lender 20 27 or Lenders being replaced and the Declining Lender's or Lenders' rights hereunder without recourse or expense to, or warranty by, such Declining Lender or Lenders being replaced for a purchase price equal to the aggregate outstanding principal amount of the Note or Notes payable to such Declining Lender or Lenders plus any accrued but unpaid interest on such Note or Notes and accrued but unpaid fees in respect of such Declining Lender's or Lenders' Loans and Commitments hereunder, and (y) all obligations of the Company owing under or in connection with this Agreement to the Declining Lender or Lenders being replaced (including, without limitation, such increased costs, breakage fees payable under Section 6.3 and all other costs and expenses payable to each such Declining Lender) shall be paid in full in immediately available funds to such Declining Lender or Lenders concurrently with such replacement, and (z) upon the payment of such amounts referred to in clauses (x) and (y), the Replacement Lender or Lenders shall each constitute a Lender hereunder and the Declining Lender or Lenders being so replaced shall no longer constitute a Lender (other than for purposes of Section 14.7), and shall no longer have any obligations hereunder, other than to the Agents pursuant to Section 15.8; or (iii) elect to revoke and cancel the extension request in such Annual Certificate of Extension by giving notice of such revocation and cancellation to the Administrative Agent (which shall promptly notify the Lenders thereof) no later than the fifth day following the date by which each Lender is required, pursuant to Section 2.2(a), to approve or disapprove the requested extension of the Aggregate Commitment. If the Company fails to timely provide the election notice referred to in this clause(c), the Company shall be deemed to have revoked and cancelled the extension request in the Annual Certificate of Extension and to have elected not to extend the Aggregate Commitment, and the concomitant Termination Date with respect to the Accepting Lenders, and on the then scheduled Termination Date the Company shall repay in full all amounts outstanding under the Loans. 2.3. Borrowing Base. (a) Initial Borrowing Base; Scheduled Semi-Annual and Discretionary Determinations of the Borrowing Base; Procedures for Determination of the Borrowing Base. The initial Borrowing Base shall be $450,000,000. The Borrowing Base shall be redetermined upon receipt by the Administrative Agent, the Co-Agent and the Lenders of the relevant Approved Engineers' Report or Company's Engineers' Report, as the case may be, pursuant to Sections 2.3(b) or (e), 4.2(d), 9.1(d), (e) or (f). Additionally, the Borrowing Base may be redetermined under each of the circumstances set forth in Sections 2.3(d), 2.3(e) and 11.1. The redeterminations of the Borrowing Base described in the preceding sentences shall be made as follows: The Administrative Agent and Co-Agent shall make a determination of the Borrowing Base in accordance with the criteria described in clause (c) of this Section 2.3 within thirty (30) days after receipt of the Approved Engineers' Report or the Company's Engineers' Report, as the case may be. Within ten (10) days following such determination, the Administrative Agent shall notify the Lenders in writing of such determination. Each Lender shall notify the Administrative Agent in writing, by telex or by facsimile transmission whether it approves or disapproves of any such determination of the Borrowing Base within ten (10) Business Days of its receipt of such notice from the Administrative Agent; provided that any Lender which does not so notify the Administrative Agent shall be deemed to have approved of such determination. Upon the approval (or deemed approval) by the Required Lenders, such determination shall thereafter be the Borrowing Base, and the Administrative Agent shall within five (5) days of such approval notify the Company in writing of such redetermined Borrowing Base. The 21 28 Administrative Agent shall promptly notify the Company and the Lenders of any change in the Borrowing Base. (b) Determination of Borrowing Base at Request of Company. The Company may request one Borrowing Base determination between regularly scheduled semi-annual redeterminations of the Borrowing Base by delivery to the Administrative Agent, the Co-Agent and the Lenders of a written request for such determination; provided that a deemed request for a determination of the Borrowing Base pursuant to Section 11.1(c), (d) or (e) shall not preclude the Company's requesting a Borrowing Base determination to which it is otherwise entitled pursuant to this clause (b). In connection with such determination the Company shall deliver to the Administrative Agent, the Co-Agent and the Lenders such reports and information concerning the Properties (which may include in the Administrative Agent's and Co-Agent's sole discretion an Approved Engineers' Report or a Company's Engineers' Report as of such date) as the Administrative Agent and the Co- Agent shall deem appropriate in their sole discretion. (c) Criteria for Determination of the Borrowing Base. Each determination by the Administrative Agent and the Co-Agent and the approval by the Required Lenders of the Borrowing Base attributable to the Properties owned by the Company and its Subsidiaries including Properties owned through partnerships (but not to exceed in each case an undivided share of such Properties equal to the Company's ownership share of such partnerships) shall be made by them in the exercise of their respective sole discretion based on their then current engineering criteria and oil and gas lending criteria, all as determined using the then most recently received Approved Engineers' Report or Company's Engineers' Report, as the case may be, and, subject to the approval of the Required Lenders to the extent set forth in clause (a) of this Section 2.3, shall be conclusive and binding in the absence of manifest error. (d) Redeterminations of Borrowing Base Upon Material Adverse Effect. In the event of: (i) the assertion or filing of any adverse claim, defect or encumbrance affecting or purporting to affect the title of the Company or any Subsidiary to any Property; or (ii) any blow out or other casualty affecting any Property or the production of oil and gas therefrom; or (iii) any withholding after one hundred twenty (120) days following commencement of production by any Person of sums due the Company or any Subsidiary in respect of Hydrocarbons produced, which withholding results from an allegation or claim affecting such Person's rights to such payment; which would have or be a Material Adverse Effect, the Administrative Agent and the Co-Agent shall have the right in their sole discretion to reduce the Borrowing Base, either temporarily or permanently, by the amount included therein with respect to the interest as to which a claim, defect, encumbrance, withholding or dispute has arisen or exists or a casualty has occurred. The failure of the Administrative Agent and the Co-Agent to make any such reduction upon receipt of any notice with respect to any such claim, dispute or casualty shall not preclude their later election to so reduce the Borrowing Base. (e) Redetermination of Borrowing Base Upon Material Changes. In the event that "material changes" occur between the dates of determination of the Borrowing Base in (i) oil and/or gas prices, (ii) taxes, (iii) anticipated rates or amounts of production from any Properties included in the Borrowing Base, (iv) the Company's or any Subsidiary's, as the case may be, title or purported title to the Properties, (v) operating, lease, royalty and other arrangements relating 22 29 to the Properties or (vi) operating costs with respect to the Properties, then in any such event the Administrative Agent and the Co-Agent may, in their sole discretion, redetermine the Borrowing Base in accordance with the standards set forth in Section 2.3(c) prior to the receipt of either a new Approved Engineers' Report or a new Company's Engineers' Report by adjusting the Borrowing Base to reflect the changes which have occurred. For the purposes hereof, "material changes" shall be deemed to have occurred for purposes of this Section 2.3(e) when such changes would in the aggregate result in a material decrease in the Borrowing Base as determined by the Administrative Agent and the Co-Agent in their sole and absolute discretion. (f) Reduction of Borrowing Base Upon Sales of Certain Properties. Upon consummation of the Sale of any Property in the Borrowing Base constituting a permitted and designated Sale under clause (iii) of Section 11.3, the Borrowing Base shall be reduced on account of such Sale by an amount equal to the proceeds of such Sale net of reasonable incidental brokerage and legal costs actually paid to third parties, net of taxes associated with such Sale payable in cash concurrently with the consummation of such Sale, and net of federal and state income taxes estimated to be due in respect of such Sale by the Company acting reasonably and in good faith, provided reserves for such taxes are established by the Company. Upon the consummation of the Sale of any Property in the Borrowing Base constituting a permitted Sale under clause (iv) of Section 11.3, the Borrowing Base shall be reduced by an amount equal to the amount of the mandatory prepayment, if any, required to be made under Section 4.2(d) on account of such Sale. (g) Title Warranty. Delivery to the Lenders of any Approved Engineers' Report or Company's Engineers' Report shall be deemed to be a reaffirmation as of the date of delivery of such report of the representation and warranties in Section 8.14. 2.4. (Intentionally Omitted.) 2.5. Facility Fee; Other Fees. (a) Facility Fee. (i) The Company agrees to pay to the Administrative Agent for the account of each Lender a facility fee for the period from (and including) the date hereof to the Termination Date, at the applicable rate per annum set forth below on such Lender's ratable portion of the Aggregate Available Commitment as in effect from time to time; provided, however, that a reduction in a Lender's portion of the Aggregate Available Commitment pursuant to Section 2.1(d) shall not reduce such Lender's ratable portion of the Aggregate Available Commitment for the purposes of this Section 2.5(a)(i): Rating of the Company's Long- Term Debt by 2 or Debt/Capitalization Ratio more Rating Agencies Facility Fee Greater than or equal to .60 to 1.0 Lower than BBB-/Baa3 .50% Greater than or equal to .60 to 1.0 BBB-/Baa3 or higher .375% Greater than or equal to .50 to 1.0 but Not applicable .375% less than .60 to 1.0 Greater than or equal to .45 to 1.0 but BBB-/Baa3 or lower .375% less than .50 to 1.0 23 30 Rating of the Company's Long-Term Debt by 2 or Debt/Capitalization Ratio more Rating Agencies Facility Fee Greater than or equal to .45 BBB/Baa2 or higher .25% to 1.0 but less than .50 to 1.0 Less than .45 to 1.0 Not applicable .25% (ii) The Company agrees to pay to the Administrative Agent for the account of each Lender a facility fee for the period from (and including) the date hereof to the Termination Date, at one-half of the rate applicable per annum set forth in clause (i) above on such Lender's ratable portion of the Aggregate Unavailable Commitment as in effect from time to time; provided, however, that a reduction in a Lender's portion of the Aggregate Available Commitment pursuant to Section 2.1(d) shall not reduce such Lender's ratable portion of the Aggregate Unavailable Commitment for the purposes of this Section 2.5(a)(ii). Facility fees accruing pursuant to this Section 2.5(a) shall be payable in arrears on each Payment Date hereafter and on the Termination Date. In addition to the foregoing, the Company agrees to pay all fees accruing prior to date hereof with respect to each Lender's commitments under the April 1992 Agreement. (b) Participation Fee. The Company agrees to pay to the Administrative Agent for the account of each Lender, on the Effective Date, a participation fee in an amount equal to .125% of each Lender's Commitment, as in effect on the Effective Date. (c) Agents' Fees. The Company shall pay to each Agent for its own respective account such fees in connection with this Agreement as previously have been agreed in a writing among them (as such writing may hereafter be amended, supplemented, restated or otherwise modified and in effect). ARTICLE III BORROWING; SELECTING RATE OPTIONS; ETC. 3.1. Method of Borrowing. (a) Revolving Loans. Not later than noon Chicago time on each Borrowing Date for Revolving Loans, each Lender shall make available its Loan or Loans, in funds immediately available in Chicago, to the Administrative Agent at its address specified pursuant to Article XVIII.

The Company shall select the Rate Option and Interest Period applicable to each Revolving Advance from time to time. The Company shall give the Administrative Agent irrevocable notice (a "Borrowing Notice") not later than (a) 10:00 a.m. Chicago time at least one (1) Business Day before the Borrowing Date of each Floating Rate Revolving Advance, and (b) 11:00 a.m. Chicago time at least three (3) Business Days before the Borrowing Date for each Eurodollar Revolving Advance, specifying: (i) the Borrowing Date, which shall be a Business Day, of such Revolving Advance, (ii) the aggregate amount of such Revolving Advance, (iii) the Rate Option selected for such Revolving Advance, and (iv) in the case of each Eurodollar Revolving Advance, the Interest Period applicable thereto. Each Eurodollar Revolving Advance shall bear interest from and including the first day of the Interest Period applicable thereto to (but not including) the last day of such Interest Period at the interest rate determined from time to time as applicable to such Eurodollar Revolving Advance. The Company shall select Interest Periods with respect to Eurodollar Revolving Advances so that it is not necessary to pay a Eurodollar Revolving Advance prior to the last day of the applicable Interest Period in order to make the mandatory repayment on the Termination Date. 3.4. Competitive Bid Loans. (a) Competitive Bid Quote Request. When the Company wishes to request offers to make Competitive Bid Loans under this Agreement, it shall transmit to the Administrative Agent by telex or telecopy a Competitive Bid Quote Request substantially in the form of Exhibit E hereto so as to be received no later than (i) 10:00 a.m. (Chicago time) at least four Business Days prior to the Borrowing Date proposed therein, in the case of a Eurodollar Auction or (ii) 9:00 a.m. (Chicago time) at least one Business Day prior to the Borrowing Date proposed therein, in the case of a Floating Rate Auction specifying: (i) the proposed Borrowing Date, which shall be a Business Day, for the proposed Competitive Bid Advance; (ii) the aggregate principal amount of such Competitive Bid Advance; (iii) whether the Competitive Bid Quotes requested are to set forth a Eurodollar Bid Rate or a Floating Bid Rate, or both; (iv) in the case of each Floating Rate Auction, the maturity date (relative to each Competitive Bid Loan, its "Stated Maturity Date") for the proposed Competitive Bid Advance (which Stated Maturity Date may not be earlier than the date occurring seven (7) days after the proposed Borrowing Date of such Competitive Bid Advance or later than the earlier of (x) the date occurring 185 days after the proposed Borrowing Date of such Competitive Bid Advance and (y) the Termination Date); and (v) in the case of each Eurodollar Bid Rate Advance, the Interest Period applicable thereto (which may not end after the Termination Date); provided that the final day of the Interest Period applicable to each Eurodollar Bid Rate Loan shall be the Stated Maturity Date thereof. 25 32 The Company may request offers to make Competitive Bid Loans for more than one Interest Period in a single Competitive Bid Quote Request. No Competitive Bid Quote Request shall be given within 5 Business Days (or such other number of days as the Company and the Administrative Agent may agree) of any other Competitive Bid Quote Request. A Competitive Bid Quote Request that does not conform substantially to the format of Exhibit E hereto shall be rejected, and the Administrative Agent shall promptly notify the Company of such rejection by telex or telecopy. (b) Invitation for Competitive Bid Quotes. Promptly and in any event before the close of business on the same Business Day of receipt of a Competitive Bid Quote Request that is not rejected pursuant to Section 3.4(a), the Administrative Agent shall send to each of the Lenders by telex or telecopy an Invitation for Competitive Bid Quotes substantially in the form of Exhibit H hereto, which shall constitute an invitation by the Company to each Lender to submit Competitive Bid Quotes offering to make the Competitive Bid Loans to which such Competitive Bid Quote Request relates in accordance with this Section 3.4. (c) Submission and Contents of Competitive Bid Quotes. (i) Each Lender may, in its sole discretion, submit a Competitive Bid Quote containing an offer or offers to make Competitive Bid Loans in response to any Invitation for Competitive Bid Quotes. Each Competitive Bid Quote must comply with the requirements of this Section 3.4(c) and must be submitted to the Administrative Agent by telex or telecopy at its offices specified pursuant to Article XVIII not later than (a) 10:00 a.m. (Chicago time) at least three Business Days prior to the proposed Borrowing Date, in the case of a Eurodollar Auction or (b) 9:00 a.m. (Chicago time) on the proposed Borrowing Date, in the case of a Floating Rate Auction (or, in either case upon reasonable prior notice to the Lenders, such other time and date as the Company and the Administrative Agent may agree); provided that Competitive Bid Quotes submitted by First Chicago may only be submitted if the Administrative Agent or First Chicago notifies the Company of the terms of the offer or offers contained therein not later than 15 minutes prior to the latest time at which the relevant Competitive Bid Quotes must be submitted by the other Lenders. Subject to Articles VII and XII, any Competitive Bid Quote so made shall be irrevocable except with the written consent of the Administrative Agent given on the instructions of the Company. (ii) Each Competitive Bid Quote shall be in substantially the form of Exhibit K hereto and shall in any case specify: a. the proposed Borrowing Date, which shall be the same as that set forth in the applicable Invitation for Competitive Bid Quotes; b. the Stated Maturity Date and the principal amount of the Competitive Bid Loan for which each such offer is being made, which principal amount (1) may be greater than, less than or equal to the Commitment of the quoting Lender, (2) must be at least $10,000,000 and an integral multiple of $1,000,000 in the case of a Eurodollar Bid Rate Advance and at least $7,000,000 and an integral multiple of $500,000 in the case of a Floating Bid Rate Advance, and (3) may not exceed the principal amount of Competitive Bid Loans for which offers were requested; c. the Competitive Bid Margin offered for each such Competitive Bid Loan; 26 33 d. the minimum amount, if any, of the Competitive Bid Loan which may be accepted by the Company; and e. the identity of the quoting Lender. (iii) The Administrative Agent shall reject any Competitive Bid Quote that: a. is not substantially in the form of Exhibit K hereto or does not specify all of the information required by Section 3.4(c)(ii); b. contains qualifying, conditional or similar language, other than any such language contained in Exhibit K hereto; c. proposes terms other than or in addition to those set forth in the applicable Invitation for Competitive Bid Quotes; or d. arrives after the time set forth in Section 3.4(c)(i). If any Competitive Bid Quote shall be rejected pursuant to this Section 3.4(c)(iii), then the Administrative Agent shall notify the relevant Lender of such rejection as soon as practical. (d) Notice to Company. The Administrative Agent shall promptly notify the Company of the terms (i) of any Competitive Bid Quote submitted by a Lender that is in accordance with Section 3.4(c) and (ii) of any Competitive Bid Quote that amends, modifies or is otherwise inconsistent with a previous Competitive Bid Quote submitted by such Lender with respect to the same Competitive Bid Quote Request. Any such subsequent Competitive Bid Quote shall be disregarded by the Administrative Agent unless such subsequent Competitive Bid Quote specifically states that it is submitted solely to correct a manifest error in such former Competitive Bid Quote. The Administrative Agent's notice to the Company shall specify the aggregate principal amount of Competitive Bid Loans for which offers have been received for each Interest Period or Stated Maturity Date specified in the related Competitive Bid Quote Request and the respective principal amounts and Eurodollar Bid Rates or Floating Bid Rates, as the case may be, so offered. (e) Acceptance and Notice by Company. Not later than (i) 11:00 a.m. (Chicago time) at least three Business Days prior to the proposed Borrowing Date, in the case of a Eurodollar Auction or (ii) 10:00 a.m. (Chicago time) on the proposed Borrowing Date, in the case of a Floating Rate Auction (or, in either case upon reasonable prior notice to the Lenders, such other time and date as the Company and the Administrative Agent may agree), the Company shall notify the Administrative Agent of its acceptance or rejection of the offers so notified to it pursuant to Section 3.4(d); provided, however, that the failure by the Company to give such notice to the Administrative Agent shall be deemed to be a rejection of all such offers. In the case of acceptance, such notice (a "Competitive Bid Borrowing Notice") shall specify the aggregate principal amount and the Interest Period and Stated Maturity Date of each offer that is accepted. The Company may accept any Competitive Bid Quote in whole or in part (subject to the terms of Section 3.4(c)(ii)d); provided that: a. the aggregate principal amount of each Competitive Bid Advance may not exceed the applicable amount set forth in the related Competitive Bid Quote Request; 27 34 b. acceptance of offers may only be made on the basis of ascending Eurodollar Bid Rates or Floating Bid Rates, as the case may be; and c. the Company may not accept any offer that is described in Section 3.4(c)(iii) or that otherwise fails to comply with the requirements of this Agreement. (f) Allocation by Administrative Agent. If offers are made by two or more Lenders with the same Eurodollar Bid Rates or Floating Rates, as the case may be, for a greater aggregate principal amount than the amount in respect of which offers are accepted for the related Interest Period, the principal amount of Competitive Bid Loans in respect of which such offers are accepted shall be allocated by the Administrative Agent among such Lenders as nearly as possible (in such multiples, not greater than $1,000,000, as the Administrative Agent may deem appropriate) in proportion to the aggregate principal amount of such offers; provided, however, that no Lender shall be allocated a portion of any Competitive Bid Advance which is less than the minimum amount which such Lender has indicated that it is willing to accept. Allocations by the Administrative Agent of the amounts of Competitive Bid Loans shall be conclusive in the absence of manifest error. The Administrative Agent shall promptly, but in any event on the same Business Day, notify each Lender of its receipt of a Competitive Bid Borrowing Notice and the aggregate principal amount of such Competitive Bid Advance allocated to each participating Lender. 3.5. Minimum Amount of Each Advance. Each requested Eurodollar Bid Rate Advance and Eurodollar Revolving Advance shall be in the minimum amount of $10,000,000 (and in multiples of $1,000,000 if in excess thereof), and each requested Floating Bid Rate Advance and Floating Rate Revolving Advance shall be in the minimum amount of $7,000,000 (and in multiples of $500,000 if in excess thereof); provided, however, that any Floating Bid Rate Advance and any Floating Rate Revolving Advance may be in the amount of the difference between (i) the Aggregate Available Commitment minus (ii) the sum of the outstanding principal amount of all Loans. 3.6. Continuation and Conversion Elections. By providing a Continuation/Conversion Notice to the Administrative Agent on or before 11:00 a.m. Chicago time, in the case of a Eurodollar Revolving Loan, or 10:00 a.m. Chicago time, in the case of a Floating Rate Revolving Loan, on a Business Day, the Company may from time to time irrevocably elect, on, in the case of a Eurodollar Revolving Loan, not less than three nor more than five, and in the case of a Floating Rate Revolving Loan not less than one or more than three, Business Days' notice, that all, or any portion in an aggregate minimum amount of $10,000,000 and an integral multiple of $1,000,000 or the remaining balance of any Revolving Loans be, in the case of Floating Rate Revolving Loans converted into Eurodollar Revolving Loans or, in the case of Eurodollar Revolving Loans converted into Floating Rate Revolving Loans or continued as Eurodollar Revolving Loans (in the absence of delivery of a Continuation/Conversion Notice with respect to any Eurodollar Revolving Loan at least three Business Days before the last day of the then current Interest Period with respect thereto, such Eurodollar Revolving Loan shall, on such last day, automatically convert to a Floating Rate Revolving Loan); provided, however, that no portion of the outstanding principal amount of any Loans may be continued as, or be converted into, a Eurodollar Advance when any Default has occurred and is continuing. 3.7. Telephonic Notices. The Company hereby authorizes the Lenders and the Administrative Agent to extend Advances, effect Rate Option selections and submit Competitive Bid Quotes based on telephonic notices made by any Person or Persons the Administrative Agent or any Lender in good faith believes to be acting on behalf of the Company. The Company agrees to deliver promptly to the Administrative Agent a written confirmation of each telephonic notice signed by an Authorized Officer. If the written confirmation differs in any material respect from the action taken by the Administrative Agent and the Lenders, the records of the Administrative Agent and the Lenders shall govern absent manifest error. 28 35 3.8. Rate after Maturity. Except as provided in the next sentence, any Advance not paid at maturity, whether by acceleration or otherwise, shall bear interest until paid in full at a rate per annum equal to the Floating Revolving Rate plus 2%. In the case of a Eurodollar Advance the maturity of which is accelerated, such Eurodollar Advance shall bear interest for the remainder of the applicable Interest Period, at the higher of the rate (including the Eurodollar Spread or the Competitive Bid Margin, as applicable) otherwise applicable to such Interest Period plus 2% per annum or the Floating Revolving Rate plus 2% per annum. 3.9. Interest Payment Dates; Determination of Interest and Fees. (a) Interest Payment Dates. (i) Interest accrued and unpaid on each Floating Rate Revolving Advance shall be payable on each Payment Date and on any date on which such Floating Rate Revolving Advance is paid or prepaid, whether due to acceleration or otherwise. Interest accrued on each Eurodollar Revolving Advance shall be payable on the last day of its applicable Interest Period and on any date on which such Eurodollar Revolving Advance is prepaid, whether due to acceleration or otherwise. Interest accrued on each Eurodollar Revolving Advance having an Interest Period longer than three (3) months shall also be payable on the last day of each three-month interval during such Interest Period. (ii) Interest on the outstanding principal amount of Competitive Bid Loans shall be payable on the Stated Maturity Date for each such Competitive Bid Loan; provided, however, that in the case of a Eurodollar Bid Rate Advance having an Interest Period longer than three (3) months, interest accrued on such Eurodollar Bid Rate Advance shall also be payable on the last day of each three-month interval during such Interest Period. Interest shall be payable for the day an Advance is made but not for the day of any payment on the amount paid if payment is received prior to noon (local time) at the place of payment. If any payment of principal of, or interest on, an Advance shall become due on a day which is not a Business Day, such payment shall be made on the next succeeding Business Day (except as provided in the definition of Interest Period) and, in the case of a principal payment, such extension of time shall be included in computing interest in connection with such payment. (b) Determination of Interest and Fees. Interest on any Advance or portion thereof bearing interest at the Floating Revolving Rate or the Floating Bid Rate and facility fees shall be calculated for actual days elapsed on the basis of a 365- or, if applicable, 366-day year, and all other interest and fees shall be calculated for actual days elapsed on the basis of a 360-day year. Changes in the Alternate Base Rate Spread and the Eurodollar Spread attributable to a change in the Debt/Capitalization Ratio or to a change in the Company's Long-term Debt Rating, if any, shall be effective on the forty-fifth (45th) day of a calendar quarter. 3.10. Notification of Advances, Interest Rates, Prepayments and Commitment Reductions. Promptly after receipt thereof, the Administrative Agent will notify each Lender of the contents of each commitment reduction notice, Borrowing Notice, Continuation/Conversion Notice, Competitive Bid Quote Request and repayment notice received by it hereunder. The Administrative Agent will notify each Lender of the Eurodollar Rate applicable to each Eurodollar Advance promptly upon determination of such Eurodollar Rate and will give each Lender prompt notice of each change in the Alternate Base Rate. Each Reference Lender agrees to furnish timely information for the purpose of determining the Eurodollar Rate. 3.11. Non-Receipt of Funds by the Administrative Agent. Unless the Company or a Lender, as the case may be, notifies the Administrative Agent prior to the date on which it is scheduled to make payment to the Administrative Agent 29 36 of (i) in the case of a Lender, the proceeds of a Loan or (ii) in the case of the Company, a payment of principal, interest, fees or other amounts to the Administrative Agent for the account of the Lenders or any Agent, that it does not intend to make such payment, the Administrative Agent may assume that such payment has been made. The Administrative Agent may, but shall not be obligated to, make the amount of such payment available to the intended recipient in reliance upon such assumption. If such Lender or the Company, as the case may be, has not in fact made such payment to the Administrative Agent, the recipient of such payment shall, on demand by the Administrative Agent, repay to the Administrative Agent the amount so made available together with interest thereon in respect of each day during the period commencing on the date such amount was so made available by the Administrative Agent until the date the Administrative Agent recovers such amount at a rate per annum equal to (i) in the case of payment by a Lender or any Agent, the Federal Funds Effective Rate for such day or (ii) in the case of payment by the Company, the interest rate applicable to the relevant Loan or, in the case of payments in respect of interest, fees or other amounts, at a rate equal to the Floating Rate. ARTICLE IV MANDATORY PAYMENTS; REDUCTIONS OF COMMITMENTS; ETC. 4.1. (Intentionally Omitted.) 4.2. Mandatory Prepayments. (a) Mandatory Prepayment on Account of Excess of Outstandings Over Aggregate Available Commitment. In the event that after giving effect to all other payments or prepayments required to be made under this Section 4.2 on any Business Day the aggregate outstanding principal amount of the Loans shall at any time exceed the Aggregate Available Commitment, the Company shall within ninety (90) days make a mandatory prepayment on the Loans in an amount equal to such excess together with all interest accrued on the amount of such prepayment to the date thereof. Notwithstanding that the Company shall have a 90-day period in which to make any mandatory prepayment specified in this Section 4.2(a), (i) the Company shall not be entitled to borrow Loans during such period without meeting the test under Section 2.1(b) and (ii) the Company shall make all other prepayments and payments required under or in connection with this Agreement as required; provided, that for purposes of the foregoing provisions of this sentence the conversion of an outstanding Eurodollar Loan into a Floating Rate Loan during such period shall not be deemed to be the borrowing of a Loan. (b) Mandatory Prepayment on Account of Sales of Certain Properties Included in the Borrowing Base. Promptly upon the consummation of any Sale of any Property included in the Borrowing Base constituting (and designated by the Company in a notice to the Administrative Agent as constituting) a permitted Sale under clause (iii) of Section 11.3 and in any event within three (3) Business Days thereof, the Company shall make a mandatory prepayment hereunder equal to the amount, if any, by which the aggregate outstanding principal amount of all Loans on the date of such mandatory prepayment exceeds the Aggregate Available Commitment (as then in effect after giving effect to any reduction thereof resulting from such Sale). (c) (Intentionally Omitted.) (d) Mandatory Prepayment on Account of Extraordinary Sales of Properties. In the event the Company or any Subsidiary proposes to consummate a Sale of any Property, which Sale is not otherwise permitted under clause (i) or (ii) of Section 11.3 or otherwise permitted and designated under clause (iii) of Section 11.3, the Company shall promptly notify the Administrative Agent, the Co-Agent and the Lenders of such proposed Sale, which notice shall describe such Property and, if known, 30 37 the proposed terms of Sale. In connection therewith the Company shall deliver to the Administrative Agent, the Co-Agent and the Lenders such reports and information concerning such Property (which may include in the Administrative Agent's and Co-Agent's sole discretion an Approved Engineers' Report or a Company's Engineers' Report as of such date) and such Sale as the Administrative Agent and the Co-Agent shall deem appropriate in their sole discretion; provided, however, that in the event the Company or any Subsidiary proposes to consummate a Sale of the type described in this Section 4.2(d), with respect to a Property not included within the Borrowing Base, no mandatory prepayment shall be required; and further, provided, that in no event shall the Borrowing Base be reduced by an amount in excess of the proceeds of such Sale net of costs, charges, and taxes incidental to the Sale, as provided in Section 2.3(f) for Sales pursuant to clause (iii) of Section 11.3. Promptly following receipt of such report and information, and upon approval of such Sale by the Administrative Agent and the Co-Agent, the Administrative Agent and the Co-Agent shall make a recommendation to the Lenders in writing of the amount of prepayment that the Company shall be required to make under this Section 4.2(d) (which amount shall also be the amount of the reduction in the Borrowing Base pursuant to Section 2.3(f)), which recommendation shall be made by the Administrative Agent and the Co-Agent in the exercise of their sole discretion. Each Lender shall notify the Administrative Agent in writing, by telex or by facsimile transmission whether it approves or disapproves (which approval or disapproval shall be made by each Lender in the exercise of its sole discretion) of such recommendation by the Administrative Agent and the Co-Agent within ten (10) Business Days of its receipt of such recommendation from the Administrative Agent; provided, that any Lender which does not so notify the Administrative Agent shall be deemed to have approved of such Sale, such amount of prepayment and such reduction in the Borrowing Base. Upon the approval of the Required Lenders, the Administrative Agent shall promptly notify the Company of such determination. The Company promptly upon the consummation of any such permitted Sale and in any event within three (3) Business Days thereof, shall, if required, make a mandatory prepayment hereunder in the amount so determined in accordance with this clause (d). (e) Application of Mandatory Prepayments. Each mandatory prepayment made under this Section 4.2 shall be applied (i) first, ratably among the Lenders with respect to any principal and interest due in connection with Revolving Loans, (ii) second, after all amounts described in clause (i) have been satisfied, ratably among those Lenders for whom any payment of principal and interest is due in connection with any Competitive Bid Loans and (iii) third, after all amounts described in clauses (i) and (ii) have been satisfied, ratably to any other Obligations then due. 4.3. Voluntary Prepayments. The Company may from time to time, at its option, prepay outstanding Advances, upon three (3) Business Days' prior notice to the Administrative Agent in the case of a Eurodollar Advance, or upon one (1) Business Day's prior notice to the Administrative Agent in the case of a Floating Rate Advance; provided that each such prepayment shall be in a minimum aggregate amount of $4,000,000 or any integral multiple of $1,000,000 in excess thereof without penalty or premium, except that if such prepayment of a Eurodollar Loan occurs prior to a last day of any applicable Interest Period, the Company shall also pay the amount specified in Section 6.3 at the time of such prepayment. Such prepayments shall be applied, at the Company's option, against outstanding Revolving Loans and Competitive Bid Loans and against installments or amounts due on account thereof in such order of application as the Company shall direct; provided, that if the Company fails to direct an order of application at or prior to the time of such notice of prepayment, then such prepayments shall be applied (i) first, ratably among the Lenders with respect to any principal and interest due in connection with Revolving Loans, (ii) second, after all amounts described in clause (i) have been satisfied, ratably among those Lenders for whom any payment of principal and interest is due in connection with any Competitive Bid Loans and (iii) third, after all amounts described in clauses (i) and (ii) have been satisfied, ratably to any other 31 38 Obligations then due; provided, further, that if, at the time of any such prepayment, any Default shall have occurred and shall be continuing, then the holders of the Obligations shall share such prepayment on a pro rata basis, based on the respective amount of Obligations owing to each such holder (whether or not matured and currently payable and whether consisting of principal, accrued interest, fees, expenses, indemnities or other types of Obligations) as of the date of occurrence of such Default. 4.4. Method of Payment. All payments of principal, interest, and fees hereunder shall be made by noon (local time at the place of payment) on the date when due in immediately available funds to the Administrative Agent at the Administrative Agent's address specified pursuant to Article XVIII, or at any other single Lending Installation of the Administrative Agent specified not less than five (5) days prior to the date when due in writing by the Administrative Agent to the Company and shall be applied (i) first, ratably among the Lenders with respect to any principal and interest due in connection with Revolving Loans, (ii) second, after all amounts described in clause (i) have been satisfied, ratably among those Lenders for whom any payment of principal and interest is due in connection with any Competitive Bid Loans and (iii) third, after all amounts described in clauses (i) and (ii) have been satisfied, ratably to any other Obligations then due; provided, however, that, if, at the time of any such payment, any Default shall have occurred and shall be continuing, then the holders of the Obligations shall share such payment on a pro rata basis, based on the respective amount of Obligations owing to each such holder (whether or not matured and currently payable and whether consisting of principal, accrued interest, fees, expenses, indemnities or other types of Obligations) as of the date of occurrence of such Default. As between the Company and any Lender, the timely receipt of any payment by the Administrative Agent from the Company for the account of such Lender shall constitute receipt by such Lender. Each payment delivered to the Administrative Agent for the account of any Lender shall be delivered promptly by the Administrative Agent to such Lender in the same type of funds which the Administrative Agent received at its address specified pursuant to Article XVIII or at any Lending Installation specified in a notice received by the Administrative Agent from such Lender. Each of the Company and the Administrative Agent shall be deemed to have complied with this Section 4.4 with respect to any payment if it shall have initiated a wire transfer to the appropriate recipient thereof and furnished such recipient with the identifying number of such wire transfer. 4.5. Notes. Each Lender is hereby authorized to record the principal amount of each of its Loans and each repayment thereof, on the schedule attached to each of its Notes, provided, however, that the failure to so record shall not affect the Company's obligations under any such Note. 4.6. Voluntary Reductions of Commitments. The Company may permanently reduce the Aggregate Commitment in whole, or in part, ratably among the Lenders, in a minimum aggregate amount of $5,000,000 or any integral multiple of $1,000,000 in excess thereof; provided, however, that the amount of the Aggregate Commitment may not be reduced to an amount which would cause it to be less than the outstanding principal amount of the Loans. All accrued facility fees shall be payable on the effective date of any such reduction or termination of the Aggregate Commitment. 4.7. Voluntary and Mandatory Prepayments. Any prepayments of principal of the Loans, whether voluntary or mandatory, shall include accrued interest to, but not including, the date of the prepayment on the principal amount being prepaid. ARTICLE V (Intentionally Omitted.) 32 39 ARTICLE VI CHANGE IN CIRCUMSTANCES; TAXES 6.1. Yield Protection. If any law or any governmental or quasi-governmental rule, regulation, policy, guideline or directive (whether or not having the force of law), or any reasonable interpretation thereof, or compliance of any Lender with such, (a) imposes or increases or deems applicable any reserve, assessment, insurance charge, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender or any applicable Lending Installation (other than reserves and assessments taken into account in determining the interest rate applicable to Eurodollar Advances), or (b) imposes any other condition the result of which is to increase the cost to any Lender or any applicable Lending Installation of making, funding or maintaining Loans or reduces any amount receivable by any Lender or any applicable Lending Installation in connection with Loans, or requires any Lender or any applicable Lending Installation to make any payment calculated by reference to the amount of Loans held or interest received, by an amount reasonably deemed material by such Lender, then, within 15 days of demand by such Lender, the Company shall pay such Lender that portion of such increased expense incurred or reduction in an amount received which such Lender reasonably determines is attributable to making, funding and maintaining its Loans and its Commitment. 6.2. Availability of Rate Options. If any Lender determines that maintenance of its Eurodollar Loans at a suitable Lending Installation would violate any applicable law, rule, regulation or directive, whether or not having the force of law, (i) the Administrative Agent shall suspend the availability of the Eurodollar Rate with respect to such Lender until such time as such situation is no longer the case, (ii) any Eurodollar Loans from such Lender then outstanding shall bear interest at the Floating Rate for the remainder of the Interest Period applicable to such Loan and (iii) until such time as such situation is no longer the case, any Eurodollar Advance made thereafter shall consist of a Floating Rate Loan made by such Lender(s) and Eurodollar Loans made by each other Lender. If the Required Lenders reasonably determine that deposits of a type or maturity appropriate to match fund Eurodollar Advances are not available, the Administrative Agent shall suspend the availability of the Eurodollar Rate with respect to any Eurodollar Advances made after the date of any such determination until such time as such situation is no longer the case. If the Required Lenders determine that the Eurodollar Rate does not accurately reflect the cost of making a Eurodollar Advance at such Eurodollar Rate, then, if for any reason whatsoever the provisions of Section 6.1 are inapplicable, the Administrative Agent shall suspend the availability of the Eurodollar Rate with respect to any Eurodollar Advances made on or after the date of any such determination until such time as such situation is no longer the case and shall require any outstanding Eurodollar Advances to be repaid. 6.3. Funding Indemnification. If any payment of a Eurodollar Advance occurs on a date which is not the last day of the applicable Interest Period, whether because of acceleration, prepayment, conversion or otherwise (except pursuant to Section 6.2), or a Eurodollar Advance is not made on the date specified by the Company for any reason other than default by the Lenders, the Company will indemnify each Lender for any loss or cost incurred by it resulting therefrom, including, without limitation, any loss or cost in liquidating or employing deposits acquired to fund or maintain the Eurodollar Advance (net of any cost or expense, unless Section 6.1, 6.5 or 6.6 is applicable thereto, which the Lender would have incurred with respect to such Eurodollar Advance had such prepayment or failure to fund not occurred). 33 40 6.4. Lending Installations. Each Lender may book its Loans at any Lending Installation selected by such Lender and may change its Lending Installation from time to time. All terms of this Agreement shall apply to any such Lending Installation and the Notes shall be deemed held by each Lender for the benefit of such Lending Installation. Each Lender may, by written or telex or facsimile notice to the Administrative Agent and the Company, designate a Lending Installation through which Loans will be made by it and for whose account Loan payments are to be made. To the extent reasonably possible, each Lender shall designate an alternate Lending Installation with respect to its Eurodollar Loans to reduce any liability of the Company to such Lender under Sections 6.1, 6.5 and 6.6 or to avoid the unavailability of a Rate Option under Section 6.2, so long as such designation is not disadvantageous to such Lender in the sole opinion of such Lender. 6.5. Increased Capital Costs. If any change in, or the introduction, adoption, effectiveness, interpretation, reinterpretation or phase-in of, any law or regulation, directive, guideline, decision or request (whether or not having the force of law) of any court, central bank, regulator or other governmental authority affects or would affect the amount of capital required or expected to be maintained by any Lender or any Person controlling such Lender, and such Lender determines (in its sole and absolute discretion) that the rate of return on its or such controlling Person's capital as a consequence of its Commitments or the Loans made by such Lender is reduced to a level below that which such Lender, or such controlling Person, as the case may be, could have achieved but for the occurrence of any such circumstance (taking into account such Person's policies as to capital adequacy), then, in any such case upon notice from time to time by such Lender to the Company, the Company shall immediately pay directly to such Lender additional amounts sufficient to compensate such Lender or such controlling Person for such reduction in rate of return. A statement of such Lender as to any such additional amount or amounts (including calculations thereof in reasonable detail) shall, in the absence of manifest error, be conclusive and binding on the Company. In determining such amount, such Lender may use any method of averaging and attribution that it (in its sole and absolute discretion) shall deem applicable. 6.6. Taxes. All payments by the Company and MW Petroleum of principal of, and interest on, the Loans and all other amounts payable hereunder and in connection herewith shall be made free and clear of and without deduction for any present or future income, excise, stamp or franchise taxes and other taxes, fees, duties, withholdings or other charges of any nature whatsoever imposed by any taxing authority, but excluding franchise taxes and taxes imposed on or measured by any Agent's or any Lender's, as applicable, net income or receipts (such non-excluded items being called "Taxes"). In the event that any withholding or deduction from any payment to be made by the Company or MW Petroleum hereunder or under any Loan Document is required in respect of any Taxes pursuant to any applicable law, rule or regulation, then the Company will (a) pay directly to the relevant authority the full amount required to be so withheld or deducted; (b) promptly forward to the Administrative Agent an official receipt or other documentation satisfactory to the Administrative Agent or the relevant Agent or Lender evidencing such payment to such authority; and (c) pay to the Administrative Agent for the account of the Agents and the Lenders such additional amount or amounts as is necessary to ensure that the net amount actually received by each Agent and Lender will equal the full amount such Agent or Lender would have received had no such withholding or deduction been required. Moreover, if any Taxes are directly asserted against any Agent or any Lender, with respect to any payment received by it hereunder or in connection herewith, the relevant Agent or Lender may pay such Taxes and the Company will promptly pay such additional amounts (including any penalties, interest or expenses) as is necessary in order that the net amount received by such Person after the payment 34 41 of such Taxes (including any Taxes on such additional amount) shall equal the amount such Person would have received had not such Taxes been asserted. If the Company fails to pay any Taxes when due to the appropriate taxing authority or fails to remit to the Administrative Agent, for the account of the respective Agents and Lenders, the required receipts or other required documentary evidence, the Company shall indemnify the Agents and the Lenders for any incremental Taxes, interest or penalties that may become payable by any Agent or Lender as a result of any such failure. For purposes of this Section 6.6, a distribution hereunder by the Administrative Agent or any other Agent or any Lender to or for the account of any Agent or Lender shall be deemed a payment by the Company. Notwithstanding the foregoing, if any Agent or any Lender not incorporated or organized under the laws of the United States of America, or a state thereof, fails to timely deliver the forms required to be delivered pursuant to Section 6.8 in a situation in which timely delivery of such forms would eliminate some or all requirements for withholding of United States federal income taxes by the Company or MW Petroleum in connection with payments under this Agreement or the other Loan Documents, then the Company shall not be required to pay or reimburse to the Lender or Agent any amount in respect of such Taxes withheld that would not have been required to be withheld if such Lender or Agent had timely delivered such forms. 6.7. Lender Statements; Survival of Indemnity; Substitution of Lenders; Limitation on Claims by Lenders. Each Agent and Lender shall deliver to the Company and the Administrative Agent a written statement of such Agent or Lender, as the case may be, as to the amount due, if any, under Sections 6.1, 6.3, 6.5 or 6.6. Such written statement shall set forth in reasonable detail the calculations upon which such Agent or Lender, as the case may be, determined such amount and shall be final, conclusive and binding on the Company in the absence of manifest error. Determination of amounts payable under such Sections in connection with a Eurodollar Loan shall be calculated as though each Lender funded its Eurodollar Loan through the purchase of a deposit of the type and maturity corresponding to the deposit used as a reference in determining the Eurodollar Rate applicable to such Loan, whether in fact that is the case or not. Unless otherwise provided herein, the amount specified in the written statement shall be payable on demand after receipt by the Company of the written statement. The obligations of the Company under Sections 6.1, 6.3, 6.5 and 6.6 shall survive payment of the Obligations and termination of this Agreement. In the event that any Lender shall deliver to the Company and the Administrative Agent a written statement as to an amount due under Section 6.1, 6.3, 6.5 or 6.6, the Company may, at its sole expense and effort, require such Lender to transfer and assign, without recourse (in accordance with Section 17.3) all of its interests, rights and obligations under this Agreement to an assignee which shall assume such assigned obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (i) such assignment shall not conflict with any law, rule or regulation or order of any court or other governmental authority, (ii) the Company shall have received a written consent of the Administrative Agent and the Co-Agent in the case of an entity that is not a Lender, which consent shall not be unreasonably withheld, (iii) the Company or such assignee shall have paid to the assigning Lender in immediately available funds the principal of and interest accrued to the date of such payment on the Loans made by it hereunder and all other amounts owed to it hereunder and the fee payable to the Administrative Agent pursuant to Section 17.3(b) and (iv) that nothing in the foregoing is intended or shall be construed as obligating any Lender to locate such an assignee. The Company shall not be required to pay to any Lender any amount under Section 6.1, 6.3, 6.5, or 6.6 in respect of any time or period more than twelve months prior to the time such Lender notifies or bills the Company of or for such amount. 6.8. Withholding Tax Exemption. At least five (5) Business Days prior to the first date on which interest or fees are payable hereunder (but in no event prior to the Effective Date) for the account of any Lender or any Agent, each Lender or Agent that is not incorporated or organized under the laws of the United States of America, or a state thereof, agrees that it will deliver to each 35 42 of the Company and the Administrative Agent two (2) duly completed copies of United States Internal Revenue Service Form 1001 or 4224, certifying in either case that such Lender or Agent, as the case may be, is entitled to receive payments under this Agreement and the Notes without deduction or withholding of any United States federal income taxes. Each Lender or Agent which so delivers a Form 1001 or 4224 further undertakes to deliver to each of the Company and the Administrative Agent two (2) additional copies of such form (or a successor form) on or before the date that such form expires (currently, three (3) successive calendar years for Form 1001 and one (1) calendar year for Form 4224) or becomes obsolete or after the occurrence of any event requiring a change in the most recent forms so delivered by it, and such amendments thereto or extensions or renewals thereof as may be reasonably requested by the Company or the Administrative Agent, in each case certifying that such Lender or Agent, as the case may be, is entitled to receive payments under this Agreement and the Notes without deduction or withholding of any United States federal income taxes, unless an event (including without limitation any change in treaty, law or regulation) has occurred prior to the date on which any such delivery would otherwise be required which renders all such forms inapplicable or which would prevent such Lender or Agent from duly completing and delivering any such form with respect to it and such Lender or Agent, as the case may be, advises the Company and the Administrative Agent that it is not capable of receiving payments without any deduction or withholding of United States federal income tax.

Upon the satisfaction by the Company of the conditions in Sections 7.1 and 7.2, each Lender shall deliver to the Company the revolving Note delivered to such Lender pursuant to the April 1992 Agreement, each such revolving Note to be marked "amended, renewed and extended." ARTICLE VIII REPRESENTATIONS AND WARRANTIES The Company represents and warrants to the Lenders and the Agents that: 8.1. Corporate Existence and Standing. The Company is a corporation, and each Subsidiary is a corporation or other legal entity, in either case duly incorporated or otherwise properly organized, validly existing and in good standing under the laws of its jurisdiction of incorporation or organization and has all requisite authority, permits and approvals, and is in good standing to conduct its business in each jurisdiction in which its business is conducted. 8.2. Authorization and Validity. The Company and each Subsidiary has the corporate or partnership power and authority and legal right to execute and deliver the Loan Documents and to perform its respective obligations thereunder. The execution and delivery by the Company and each Subsidiary of the Loan Documents to which it is a party and the performance of its obligations thereunder have been duly authorized by proper corporate or partnership proceedings, and the Loan Documents have been duly executed and delivered and constitute legal, valid and binding obligations of the Company and each Subsidiary enforceable against the Company and each Subsidiary in accordance with their terms, except as enforceability may be limited by bankruptcy, insolvency or similar laws affecting the enforcement of creditors' rights generally. 8.3. No Conflict; Government Consent. Neither the execution and delivery by the Company and each Subsidiary of the Loan Documents nor the consummation of the transactions therein contemplated, nor compliance with the provisions thereof will violate any law, rule, regulation, order, writ, judgment, injunction, decree or award binding on the Company or any Subsidiary or the Company's or any Subsidiary's articles of incorporation or by-laws or partnership agreement or the provisions of any indenture, instrument or agreement to which the Company or any Subsidiary is a party or is subject, or by which it, or its property, is bound, or conflict with or constitute a default thereunder, or result in the creation or imposition of any Lien in, of or on all or any part of the property of the Company or any Subsidiary. No order, consent, approval, license, authorization, or validation of, or filing, recording or registration with, or exemption by, any governmental or public body or authority, or any subdivision thereof, is required to authorize, or is required in connection with the execution, delivery and performance of, or the legality, validity, binding effect or enforceability of, any of the Loan Documents. 8.4. Financial Statements. The consolidated financial statements of the Company dated December 31, 1993 heretofore delivered to the Lenders were prepared in accordance with generally accepted accounting principles in effect on the date such statements were prepared and fairly present the consolidated financial condition of the Company and the Subsidiaries at such date and the consolidated results of their operations for the period then ended. 8.5. Material Adverse Change. Since December 31, 1993, there has been no change in the business, assets, properties, operations, condition (financial or otherwise) or results of operations or prospects of the Company and its Subsidiaries or MW Petroleum and its Subsidiaries or any legal or regulatory development which could have or be a Material Adverse Effect. 8.6. Taxes. The Company and the Subsidiaries have filed all United States federal tax returns and all other tax returns which are required to be filed and have paid all taxes due pursuant to said returns or pursuant to any 38 45 assessment received by the Company or any Subsidiary, except such taxes, if any, as are being contested in good faith and as to which adequate reserves have been provided. The United States income tax returns of the Company and the Subsidiaries (other than MW Petroleum and MWJR) have been audited by the Internal Revenue Service or, if no audit was performed, the statute of limitations permitting such an audit has run, through the fiscal year ended December 31, 1982. No tax liens have been filed and no claims are being asserted with respect to any such taxes. The charges, accruals and reserves on the books of the Company and the Subsidiaries in respect of any taxes or other governmental charges are adequate. 8.7. Litigation and Contingent Obligations. There is no litigation, arbitration, governmental investigation, proceeding or inquiry pending or, to the knowledge of any of their officers, threatened against or affecting the Company or any Subsidiary which is or could have a Material Adverse Effect. The Company and its Subsidiaries have no material contingent obligations not provided for or disclosed in the financial statements referred to in Section 8.4. 8.8. Subsidiaries. Schedule 8.8 hereto contains an accurate list of all of the presently existing Subsidiaries of the Company as of the date of this Agreement, setting forth their respective jurisdictions of incorporation or organization and the percentage of their respective capital stock or, the revenue share attributable to the general and limited partnership interests, as the case may be, owned by the Company or other Subsidiaries. All of the issued and outstanding shares of capital stock of such Subsidiaries which are corporations have been duly authorized and issued and are fully paid and non-assessable. 8.9. ERISA. The Unfunded Liabilities of all Plans do not in the aggregate exceed $5,000,000. Each Plan complies in all material respects with all applicable requirements of law and regulations, no Reportable Event has occurred with respect to any Plan, neither the Company nor any other members of the Controlled Group has withdrawn from any Plan or initiated steps to do so, and no steps have been taken to terminate any Plan. 8.10. Accuracy of Information. No information, exhibit or report furnished by the Company or any Subsidiary to any Agent or to any Lender in connection with the negotiation of, or compliance with, the Loan Documents contained any material misstatement of fact or omitted to state a material fact or any fact necessary to make the statements contained therein not misleading. 8.11. Regulation-U. Margin stock (as defined in Regulation U) constitutes less than 25% of those assets of the Company and the Subsidiaries which are subject to any limitation on sale, pledge, or other restriction hereunder. 8.12. Material Agreements. Neither the Company nor any Subsidiary is in default in the performance, observance or fulfillment of any of the obligations, covenants or conditions contained in (i) any agreement to which it is a party, which default might have a Material Adverse Effect or (ii) any agreement or instrument evidencing or governing Indebtedness. 8.13. Compliance With Laws. The Company and the Subsidiaries have complied in all material respects with all applicable statutes, rules, regulations, orders and restrictions of any domestic or foreign government or any instrumentality or agency thereof, having jurisdiction over the conduct of their respective businesses or the ownership of their respective Properties. Neither the Company nor any of the Subsidiaries has received any notice to the effect that it, its operations or the Properties are not in material compliance with any of the requirements of applicable federal, state or local environmental, health and safety statutes and regulations, or are the subject of any federal or state investigation evaluating whether any remedial action is needed to respond to a release of any toxic or hazardous waste or substance into the environment, whether from the Properties or elsewhere, which in any case would have a Material Adverse Effect. 39 46 8.14. Title to Properties. Each of the Company and the Subsidiaries has legal, valid and defensible title to substantially all of its properties and assets and valid and defensible title, whether legal or beneficial, to all of its properties and assets, free and clear of any and all Liens other than those Liens permitted by Section 11.5. The 1994 Engineers' Report refers to and covers all of the reserves in the Properties as of the Effective Date and such Report covers no reserves other than in such Properties. 8.15.

All remedies contained in the Loan Documents or afforded by law shall be cumulative and all shall be available to the Agents and the Lenders until the Obligations have been paid in full. No delay or omission of the Lenders, the Agents or any of them to exercise any right under the Loan Documents shall impair such right or be construed to be a waiver of any Default or an acquiescence therein, and the making of a Loan notwithstanding the existence of a Default or the inability of the Company to satisfy the conditions precedent to such Loan shall not constitute any waiver or acquiescence. Any single or partial exercise of any such right shall not preclude other or further exercise thereof or the exercise of any other right, and no waiver, amendment or other variation of the terms, conditions or provisions of the Loan Documents whatsoever shall be valid unless in writing signed by the Lenders and the Agents required pursuant to Section 13.2, and then only to the extent specifically set forth in such writing.

Each Lender agrees to reimburse and indemnify each of the Administrative Agent, the Collateral Agent, the Co-Agent ratably in proportion to such Lender's Aggregate Commitments, (i) for any amounts (other than principal or interest) not reimbursed by the Company or the Guarantor for which such Agent is entitled to reimbursement by the Company under the Loan Documents, and (ii) for any liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind and nature whatsoever which may be imposed on, incurred by or asserted against such Agent in any way relating to or arising out of the Loan Documents or any other document delivered in connection therewith or the transactions contemplated thereby, or the enforcement of any of the terms thereof or of any such other documents, provided that no Lender shall be so liable to the extent any of the foregoing is found by a final order of a court of competent 59 66 jurisdiction to have arisen solely from such Agent's gross negligence or willful misconduct. 15.9. Rights as a Lender. With respect to its Commitments, Loans made by it and the Notes issued to it, each Agent shall have the same rights and powers hereunder and under each other Loan Document as any Lender and may exercise the same as though it did not hold such role, and the term "Lender" or "Lenders" shall, unless the context otherwise indicates, include each of them in its individual capacity. In addition to, and not by way of limitation of the rights set forth in Section 14.14, each Agent may accept deposits from, lend money to, and generally engage in any kind of banking or trust business with the Company or any Subsidiary or any other Affiliate of the Company as if it did not hold such role. 15.10. Lender Credit Decision. Each Lender acknowledges that it has, independently and without reliance upon any Agent or any other Lender and based on the financial statements prepared by the Company and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement and the other Loan Documents. Each Lender also acknowledges that it will, independently and without reliance upon any Agent or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement and the other Loan Documents. 15.11. Certain Successor Agents. Any Agent may resign at any time by giving thirty (30) days' prior written notice thereof to the Lenders and the Company. Upon any such resignation, the Company shall, if no Default or Unmatured Default has occurred and is continuing, have the right (subject to the consent of the Required Lenders) to appoint, on behalf of the Company and the Lenders, a Lender as a successor Agent. If no successor Agent shall have been so appointed by the Company and shall have accepted such appointment within thirty (30) days' after the retiring Agent's giving notice of resignation, then the retiring Agent may appoint, on behalf of the Company and the Lenders, a Lender as a successor Agent; provided, however, that the Company may, within the one year period following the appointment of a successor Agent, and upon thirty (30) days written notice to the Lenders, remove the successor Agent and appoint a successor Agent acceptable to the Company (subject to the consent of the Required Lenders). Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and Obligations (but not any liability arising from its gross negligence or wilful misconduct as established by a final order of a court of competent jurisdiction) hereunder and under the other Loan Documents. After any retiring Agent's resignation hereunder as Agent, the provisions of this Article XV shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was acting as an Agent hereunder and under the other Loan Documents. ARTICLE XVI SETOFF; RATABLE PAYMENTS 16.1. Setoff. In addition to, and without limitation of, any rights of the Lenders under applicable law, if the Company becomes insolvent, however evidenced, or any Default or Unmatured Default occurs, any indebtedness from any Lender to the Company (including all account balances, whether provisional or final and whether or not collected or available) may be offset and applied toward the payment of the Obligations owing to such Lender, whether or not the Obligations, or any part hereof, shall then be due and payable. 16.2. Ratable Payments. If any Lender, whether by setoff or otherwise, has payment made to it upon its Loans in a greater proportion than it would have received pursuant to an allocation using the method set forth in Section 4.3 or 4.4 (except for payments made to Lenders with respect to 1992 Revolving Loans which are outstanding on the Effective Date including, without limitation, 60 67 payments made to Banque Indosuez and Norwest Bank Denver, N.A. pursuant to Section 9.16), such Lender agrees, promptly upon demand, to purchase a portion of the Loans held by the other Lenders so that after such purchase each Lender will hold its ratable proportion of such type of Loans. If any Lender, whether in connection with setoff or amounts which might be subject to setoff or otherwise, receives collateral or other protection for its Obligations or such amounts which may be subject to set off, such Lender agrees, promptly upon demand, to take such action necessary such that all Lenders share in the benefits of such collateral ratably in proportion to the Obligations owing to each of them. In case any such payment is disturbed by legal process, or otherwise, appropriate further adjustments shall be made. ARTICLE XVII BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS 17.1. Successors and Assigns. The terms and provisions of the Loan Documents shall be binding upon and inure to the benefit of the Company, the Agents and the Lenders and their respective successors and assigns, except that the Company shall not have the right to assign its rights or obligations under the Loan Documents and any assignment by any Lender must be made in compliance with Section 17.3. The Administrative Agent and the Collateral Agent may treat the payee of any Note as the owner thereof for all purposes hereof unless and until such payee complies with Section 17.3 in the case of an assignment thereof or, in the case of any other transfer, a written notice of the transfer is filed with such Agent. Any assignee or transferee of a Note agrees by acceptance thereof to be bound by all the terms and provisions of the Loan Documents. Any request, authority or consent of any Person, who at the time of making such request or giving such authority or consent is the holder of any Note, shall be conclusive and binding on any subsequent holder, transferee or assignee of such Note or of any Note or Notes issued in exchange therefor. 17.2. Participations. (a) Any Lender, in the ordinary course of its business and in accordance with applicable law, at any time may sell to one or more banks or other entities ("Participants") participating interests in any Loan owing to such Lender, any Note held by such Lender, any Commitment of such Lender or any other interest of such Lender under the Loan Documents. In the event of any such sale by a Lender of participating interests to a Participant, such Lender's Obligations under the Loan Documents shall remain unchanged, such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, such Lender shall remain the holder of any such Note or Obligation for all purposes under the Loan Documents, and the Company and the Agents shall continue to deal solely and directly with such Lender in connection with such Lender's rights and obligations under the Loan Documents. (b) Each Lender shall retain the sole right to approve, without the consent of any Participant, any amendment, modification or waiver of any provision of the Loan Documents other than any amendment, modification or waiver with respect to any Loan or Commitment in which such Participant has an interest which forgives principal, interest or fees or reduces the interest rate or fees payable with respect to any such Loan or Commitment, postpones any date fixed for any regularly-scheduled payment of principal of, or interest or fees on, or reimbursement obligation with respect to, any such Loan or Commitment, releases any guarantor of any such Obligation or releases all or substantially all of the collateral (except as permitted by Section 13.2(d)), if any, securing any such Obligation. (c) The Company agrees that each Participant shall be deemed to have the right of setoff provided in Section 16.1 in respect of its participating interest in amounts owing under the Loan Documents to the same extent as if the amount of its participating interest were owing directly to it as a Lender under the Loan Documents, provided that each 61 68 Lender shall retain the right of setoff provided in Section 16.1 with respect to the amount of participating interests sold to each Participant. The Lenders agree to share with each Participant, and each Participant, by exercising the right of setoff provided in Section 16.1, agrees to share with each Lender, any amount received pursuant to the exercise of its right of setoff, such amounts to be shared in accordance with Section 16.2 as if each Participant were a Lender. The Company also agrees that each Participant shall be entitled to the benefits of Sections 6.1 and 6.3 with respect to its participation in the Commitments or the Loans outstanding from time to time; provided, that no Participant shall be entitled to receive any greater amount pursuant to such Sections than the transferor Lender would have been entitled to receive in respect of the amount of the participation transferred by such transferor Lender to such Participant had no such transfer occurred. 17.3. Assignments. (a) Any Lender may, in the ordinary course of its business and in accordance with applicable law and with the consent of the Company, at any time assign to one or more banks or other entities ("Purchasers") all or any part of its rights and obligations under the Loan Documents subject to a minimum of $15,000,000 or such lesser amount as may be agreed to by the Company; provided that with respect to any Purchaser which is an Affiliate of such Lender, such consent of the Company shall not be unreasonably withheld. Such assignment shall be substantially in the form of Exhibit "D" hereto. The consent of the Administrative Agent shall also be required prior to an assignment becoming effective with respect to a Purchaser which is not a Lender. All such consents shall be substantially in the form attached as Exhibits "D-II" or "D- III" to Exhibit "D" hereto and shall not be unreasonably withheld. (b) Upon (i) delivery to the Administrative Agent of a notice of assignment, substantially in the form attached as Exhibit "D-I" to Exhibit "D" hereto (a "Notice of Assignment"), together with any consents required by Section 17.3.(a), and (ii) payment of a $2,500 fee to the Administrative Agent for processing such assignment, such assignment shall become effective on the effective date specified in such Notice of Assignment; provided, however, that any amounts paid by the Company to, or for the benefit of, the assigning Lender, on or before the execution date of the assignment, if such date is later than the effective date of the assignment, shall be deemed paid to and for the benefit of the Purchaser for all purposes. On and after the effective date of such assignment, such Purchaser shall for all purposes be a Lender, party to this Agreement and any other Loan Document executed by the Lenders, and shall have all the rights and obligations of a Lender under the Loan Documents, to the same extent as if it were an original party hereto, and no further consent or action by the Company, the Lenders or any Agent shall be required to release the transferor Lender, with respect to the percentages of the Commitment, and the Loans assigned to such Purchaser and the transferor Lender shall henceforth be so released. Upon the consummation of any assignment to a Purchaser pursuant to this Section 17.3(b), the Company shall issue replacement Notes to such transferor Lender and shall issue new Notes or, as appropriate, replacement Notes, to such Purchaser, in each case in principal amounts reflecting their respective Commitments, as adjusted pursuant to such assignment. (c) The provisions of the foregoing clauses (a) and (b) shall not apply to or restrict, or require the consent of or notice to any Person to effectuate, the pledge or assignment by any Agent or Lender of its rights or obligations under any Loan Documents to any Federal Reserve Bank. 17.4. Dissemination of Information. The Company authorizes each Agent and each Lender to disclose to any Participant or Purchaser or any other Person acquiring an interest in the Loan Documents by operation of law (each a "Transferee") and any prospective Transferee any and all information in such 62 69 Lender's possession concerning the creditworthiness of the Company and the Subsidiaries, provided that such Transferee and prospective Transferee agrees in writing to be bound by Section 14.13 of this Agreement. 17.5. Tax Treatment. If any interest in any Loan Document is transferred to any Transferee which is organized under the laws of any jurisdiction other than the United States or any State thereof, the transferor Lender shall cause such Transferee, concurrently with the effectiveness of such transfer, to comply with the provisions of Section 6.8. ARTICLE XVIII NOTICES 18.1. Giving Notice. Except as otherwise permitted by Section 4.5 with respect to borrowing notices, all notices and other communications provided to any party hereto under this Agreement or any other Loan Document shall be in writing or by telex or by facsimile and addressed or delivered to such party at its address set forth below its signature hereto or at such other address as may be designated by such party in a notice to the other parties. Any notice, if mailed and properly addressed with postage prepaid, shall be deemed given when received; any notice, if transmitted by telex or facsimile, shall be deemed given when transmitted (answerback confirmed in the case of telexes). 18.2. Change of Address. The Company, the Administrative Agent, the Co-Agent, the Collateral Agent and the Lenders may each change the address for service of notice upon it by a notice in writing to the other parties hereto. ARTICLE XIX COUNTERPARTS This Agreement may be executed in any number of counterparts, all of which taken together shall constitute one agreement, and any of the parties hereto may execute this Agreement by signing any such counterpart. This Agreement shall be effective when it has been executed by the Company, the Agents and the Lenders and each party has notified the Administrative Agent, by telex, facsimile or telephone, that it has taken such action. ARTICLE XX NO ORAL AGREEMENTS THIS WRITTEN AGREEMENT, THE NOTES, 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 AMONG THE PARTIES. IN WITNESS WHEREOF, the Company, the Lenders and the Agents have executed this Agreement as of the date first above written.
