Each Lender acknowledges and agrees that its obligation to acquire participations pursuant to this paragraph in respect of Letters of Credit is absolute and unconditional and shall not be affected by any circumstance whatsoever, including any amendment, renewal or extension of any Letter of Credit or the occurrence and continuance of a Default or reduction or termination of the Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever.

2.20.5 Reimbursement. If the LC Issuer shall make any LC Disbursement in respect of a Letter of Credit, the Borrower shall reimburse such LC Disbursement by paying to the Agent an amount equal to such LC Disbursement not later than 12:00 noon on the date that such LC Disbursement is made, if the Borrower shall have received notice of such LC Disbursement prior to 10:00 a.m. on such date, or, if such notice has not been received by the Borrower prior to such time on such date, then not later than 12:00 noon on the Business Day immediately following the day that the Borrower receives such notice. If the Borrower fails to make such payment when due, the Agent shall notify each Lender of the applicable LC Disbursement, the payment then due from the Borrower in respect thereof and such Lender's Pro Rata Share thereof. Promptly following receipt of such notice, each Lender shall pay to the Agent its Pro Rata Share of the payment then due from the Borrower, in the same manner as provided in this Article with respect to Loans made by such Lender, and the Agent shall promptly pay to the LC Issuer the amounts so received by it from the Lenders. Promptly following receipt by the Agent of any payment from the

Borrower pursuant to this paragraph, the Agent shall distribute such payment to the LC Issuer or, to the extent that Lenders have made payments pursuant to this paragraph to reimburse the LC Issuer, then to such Lenders and the LC Issuer as their interests may appear. Any payment made by a Lender pursuant to this paragraph to reimburse the LC Issuer for any LC Disbursement shall not constitute a Loan and shall not relieve the Borrower of its obligation to reimburse such LC Disbursement.

2.20.6 Obligations Absolute. The Borrower's obligation to reimburse LC Disbursements as provided in Section 2.20.5 shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement under any and all circumstances whatsoever and irrespective of (i) any lack of validity or enforceability of any letter of credit application, any Letter of Credit or this Agreement, or any term or provision therein, (ii) any draft or other document presented under a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect, (iii) payment by the LC Issuer under a Letter of Credit against presentation of a draft or other document that does not comply with the terms of such Letter of Credit or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section, constitute a legal or equitable discharge of, or provide a right of setoff against, the Borrower's Obligations hereunder. None of the Agent, the Lenders or the LC Issuer, nor any of their Affiliates, shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of the LC Issuer, provided that the foregoing shall not be construed to excuse the LC Issuer from liability to the Borrower to the extent of any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by the Borrower to the extent permitted by applicable law) suffered by the Borrower that are caused by the LC Issuer's failure to exercise care when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof. The parties hereto expressly agree that, in the absence of gross negligence or willful misconduct on the part of the LC Issuer (as finally determined by a court of competent jurisdiction), the LC Issuer shall be deemed to have exercised care in each such determination. In furtherance of the foregoing and without limiting the generality thereof, the parties agree that, with respect to documents presented that appear on their face to be in substantial compliance with the terms of a Letter of Credit, the LC Issuer may, in its sole discretion, either accept and make payment upon such documents without responsibility for further investigation, unless it has received written notice to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit.

2.20.7 Disbursement Procedures. The LC Issuer shall, promptly following its receipt thereof, examine all documents purporting to represent a demand for payment under a Letter of Credit. The LC Issuer shall promptly notify the Agent and the Borrower by telephone (confirmed by telecopy) of such demand for payment and whether the LC Issuer has made or will make an LC Disbursement thereunder, provided that any failure to give or delay in giving such notice shall not relieve the Borrower of its obligation to reimburse the LC Issuer and the Lenders with respect to any such LC Disbursement.

2.20.8 Interim Interest. If the LC Issuer shall make any LC Disbursement, then, unless the Borrower shall reimburse such LC Disbursement in full on the date such LC Disbursement is made, the unpaid amount thereof shall bear interest, for each day from and including the date such LC Disbursement is made to but excluding the date that the Borrower reimburses such LC Disbursement, at the rate per annum then applicable to Floating Rate Advances, provided that, if the Borrower fails to reimburse such LC Disbursement when due pursuant to Section 2.20.5 hereof, then Section 2.11 shall apply. Interest accrued pursuant to this paragraph shall be for the account of the LC Issuer, except that interest accrued on and after the date of payment by any Lender pursuant to Section 2.20.5 hereof to reimburse the LC Issuer shall be for the account of such Lender to the extent of such payment.

2.20.9 Replacement of the LC Issuer. The LC Issuer may be replaced at any time by written agreement among the Borrower, the Agent, the replaced LC Issuer and the successor LC Issuer. The Agent shall notify the Lenders of any such replacement of the LC Issuer. At the time any such replacement shall become effective, the Borrower shall pay all unpaid fees accrued for the account of the replaced LC Issuer. From and after the effective date of any such replacement, (i) the successor LC Issuer shall have all the rights and obligations of the LC Issuer under this Agreement with respect to Letters of Credit to be issued thereafter and (ii) references herein to the term "LC Issuer" shall be deemed to refer to such successor or to any previous LC Issuer, or to such successor and all previous LC Issuers, as the context shall require. After the replacement of an LC Issuer hereunder, the replaced LC Issuer shall remain a party hereto and shall continue to have all the rights and obligations of an LC Issuer under this Agreement with respect to Letters of Credit issued by it prior to such replacement, but shall not be required to issue additional Letters of Credit.

2.20.10 Cash Collateralization. If any Default shall occur and be continuing or if the Aggregate Commitments shall be terminated for any reason, on the Business Day that the Borrower receives notice from the Agent demanding the deposit of cash collateral pursuant to this paragraph, the Borrower shall deposit in an account with the Agent, in the name of the Agent and for the benefit of the Lenders, an amount in cash equal to the LC Exposure as of such date plus any accrued and unpaid interest thereon, provided that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become immediately due and payable, without demand or other notice of any kind, upon the occurrence of any Default with respect to the Borrower described in Section 7.6 or Section 7.7 hereof. Each such deposit shall be held by the Agent as collateral for the payment and performance of the Obligations of the Borrower under this Agreement. The Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account. Other than any interest earned on the investment of such deposits, which investments shall be made at the option and sole discretion of the Agent and at the Borrower's risk and expense, such deposits shall not bear interest. Interest or profits, if any, on such investments shall accumulate in such account. Moneys in such account shall be applied by the Agent to reimburse the LC Issuer for LC Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the Borrower for the LC Exposure at such time or, if the maturity of the Advances has been accelerated, be applied to satisfy other Obligations of the Borrower under

this Agreement. If the Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of a Default, such amount (to the extent not applied as aforesaid) shall be returned to the Borrower within three Business Days after all Defaults have been cured or waived.

2.20.11 Letter of Credit Fees. The Borrower shall pay to the Agent for the account of each Lender in accordance with its Pro Rata Share a Letter of Credit fee for each Letter of Credit equal to the rate per annum then applicable to Eurodollar Advances (which rate shall be determined in accordance with Section 2.11 hereof after the occurrence of any Default) times the actual daily maximum amount available to be drawn under each Letter of Credit. Such fee for each Letter of Credit shall be due and payable on the last Business Day of each March, June, September and December, commencing with the first such date to occur after the issuance of such Letter of Credit, and on the expiration of the LC Availability Period. If there is any change in the Eurodollar Rate during any quarter, the actual daily amount of each Letter of Credit shall be computed and multiplied by the applicable Eurodollar Rate separately for each period during such quarter that such applicable Eurodollar Rate was in effect.

2.20.12 Fronting Fee and Documentary and Processing Charges Payable to LC Issuer. The Borrower shall pay directly to the LC Issuer for its own account a fronting fee with respect to each Letter of Credit equal to ¹/8 of one percent per annum on the daily maximum amount available to be drawn thereunder due and payable quarterly in arrears on the last Business Day of each March, June, September and December, commencing with the first such date to occur after the issuance of such Letter of Credit, and on the expiration of the LC Availability Period. In addition, the Borrower shall pay directly to the LC Issuer for its own account the customary issuance, presentation, amendment and other processing fees, and other standards costs and charges, of the LC Issuer relating to letters of credit from time to time in effect. Such fees and charges are due and payable on demand and are not refundable.

2.21 Borrowing Base.

2.21.1 Definition; Initial Borrowing Base. The term "Borrowing Base" means, as of the date of determination thereof, an amount as determined by the Agent with the approval of the Required Lenders in their discretion in accordance with then-current practices, economic and pricing parameters, and customary procedures and standards established by them from time to time for their petroleum industry customers including without limitation (a) an analysis of such reserve and production data with respect to the Mineral Interests of the Borrower in all of its oil and gas properties, including the Mortgaged Properties, as is provided to the Agent in accordance herewith, (b) an analysis of the assets, liabilities, cash flow, business, properties, prospects, management and the ownership of the Borrower and its Affiliates, and (c) such other credit factors consistently applied as the Lenders customarily consider in evaluating similar oil and gas credits. The Agent and the Lenders have no obligation to agree upon or determine the Borrowing Base at any particular amount, whether in relation to the Aggregate Commitments or otherwise. If the Required Lenders cannot agree on the amount of the Borrowing Base, then the Borrowing Base shall be determined on the basis of the weighted arithmetic average of the Borrowing Base as determined by the each individual Lender. Notwithstanding anything to the contrary contained herein, the amount of the Borrowing Base may not be increased at any time without the consent of 100% of the Lenders. The Borrowing Base shall initially be $40,000,000.

2.21.2 Periodic Determinations of Borrowing Base. The Borrowing Base shall be redetermined by the Lenders as of October 1 and April 1 of each year (each a "Determination Date") until maturity, commencing October 1, 2002. The Borrowing Base, as redetermined, shall remain in effect until the next Determination Date, provided the Borrowing Base may be redetermined between Determination Dates in accordance with Section 2.21.4 hereof.

2.21.3 Engineering Data to be Provided Prior to Scheduled Determination Dates.

(a) On or before February 15 of each year for the Determination Date of April 1, the Borrower shall deliver to the Agent a Reserve Report. Bank shall then determine the Borrowing Base for the six (6) month period commencing April 1.

(b) On or before August 15 of each year for the Determination Date of October 1, the Borrower shall deliver to the Agent such information, reports and data pertaining to Mineral Interests of the Borrower in all of its oil and gas properties, including those oil and gas properties which constitute the Mortgaged Properties, as the Agent may reasonably request. Such information shall (i) set forth the historical production data of the oil and gas reserves included in such properties, (ii) set forth for each property prices received for production, lease operating expenses, capital expenditures, gross revenues, net revenues, taxes and such other information as Bank may deem necessary or appropriate, (iii) set forth for each property any changes since the date of most recent Reserve Report, if any, in its working interest or net revenue interest therein, and (iv) be accompanied by a certification of the Borrower to the effect that no material adverse changes have occurred since the date of the last Reserve Report except those which have previously been disclosed to the Agent in writing. The Lenders shall then determine the Borrowing Base for the next six (6) month period.

2.21.4 Special Determinations of Borrowing Base. Special determinations of the Borrowing Base may be requested by the Borrower not more than one (1) time per calendar year or by the Lenders at any time during the term hereof. If any special determination is requested by the Borrower, it shall be accompanied by engineering data described in Section 2.21.3(b) and a deposit in the amount of $5,000 for each Lender for the administrative fees of each Lender. If any special determination is requested by the Lenders, the Borrower will provide the Agent with the information specified in Section 2.21.3(b) hereof as soon as is reasonably possible following the request. The determination whether to increase or decrease the Borrowing Base shall then be made by the Lenders in their sole discretion in accordance with the standards set forth in Section 2.21.1 hereof. In the event of any special determination of the Borrowing Base pursuant to this Section, the Lenders in the exercise of their discretion may suspend the next regularly scheduled determination of the Borrowing Base.

2.21.5 Borrowing Base Deficiency. If by reason of any adjustment to the Borrowing Base, the total Revolving Exposure then outstanding exceeds the amount of the Borrowing Base, then the Agent shall notify the Borrower of the same, and Borrower shall within thirty (30) days following receipt of such notice elect whether to (i) prepay an amount which will reduce the total Revolving Exposure to the amount of the Borrowing Base, or (ii) execute and deliver to the Agent instruments mortgaging such other collateral as is acceptable to the Lenders, pursuant to security documents acceptable to the Agent having present values which, in the opinion of the Lenders, based upon the Lenders' evaluation of the engineering data provided it, taken in the aggregate are sufficient to increase the Borrowing Base to an amount at least equal to the total Revolving Exposure then outstanding, or (iii) do any combination of the foregoing as is acceptable to the Agent. If the Borrower so elects to mortgage additional oil and gas properties, then clause (ii) above shall be accomplished within forty-five (45) days from the Agent's date of notification. If the Borrower fails to make an election among clauses (i) through (iii) above within thirty (30) days from the Agent's notification, then the Borrower shall be deemed to have selected the payment option specified in clause (i) thereof.

2.21.6 Borrowing Base Increase Fee. A fee shall be paid for each incremental increase in the new Borrowing Base over the previously existing Borrowing Base. The amount of each such fee shall be one quarter of one percent (0.25%) of the incremental increase. There shall be no obligation imposed upon the Borrower to accept an increase of the Borrowing Base proposed by the Lenders. However, if the Borrower accepts the increase in the Borrowing Base, the fee shall be

due and payable immediately and without regard as to whether the Borrower ever borrows the increased amount available under such new Borrowing Base. Determinations of when a fee is due shall be made by Bank and shall be conclusive and binding on the parties absent manifest error. Determinations of when a fee is due shall be made by the Agent and shall be conclusive and binding on the parties absent manifest error.

2.22 Arrangement and Agency Fees. In addition to the fees payable pursuant to Sections 2.5, 2.20.11, 2.20.12, and 2.21.6, the Borrower shall pay an arrangement fee to the Arranger for the Arranger's own account, and shall pay an agency fee to the Agent for the Agent's own account, in the amounts and at the times specified in separate written agreements with the Arranger and with the Agent. Such fees shall be fully earned when paid and shall be nonrefundable for any reason whatsoever.

2.23 Limitation of Interest. The Borrower, the Agent and the Lenders intend to strictly comply with all applicable laws, including applicable usury laws. Accordingly, the provisions of this Section 2.23 shall govern and control over every other provision of this Agreement or any other Loan Document which conflicts or is inconsistent with this Section 2.23, even if such provision declares that it controls. As used in this Section 2.23, the term "interest" includes the aggregate of all charges, fees, benefits or other compensation which constitute interest under applicable law, provided that, to the maximum extent permitted by applicable law, (a) any non-principal payment shall be characterized as an expense or as compensation for something other than the use, forbearance or detention of money and not as interest, and (b) all interest at any time contracted for, reserved, charged or received shall be amortized, prorated, allocated and spread, in equal parts during the full term of the Obligations. In no event shall the Borrower or any other Person be obligated to pay, or any Lender have any right or privilege to reserve, receive or retain, (a) any interest in excess of the maximum amount of nonusurious interest permitted under the laws of the State of Texas or the applicable laws (if any) of the United States or of any other applicable state, or (b) total interest in excess of the amount which such Lender could lawfully have contracted for, reserved, received, retained or charged had the interest been calculated for the full term of the Obligations at the Highest Lawful Rate. On each day, if any, that the interest rate (the "Stated Rate") called for under this Agreement or any other Loan Document exceeds the Highest Lawful Rate, the rate at which interest shall accrue shall automatically be fixed by operation of this sentence at the Highest Lawful Rate for that day, and shall remain fixed at the Highest Lawful Rate for each day thereafter until the total amount of interest accrued equals the total amount of interest which would have accrued if there were no such ceiling rate as is imposed by this sentence. Thereafter, interest shall accrue at the Stated Rate unless and until the Stated Rate again exceeds the Highest Lawful Rate when the provisions of the immediately preceding sentence shall again automatically operate to limit the interest accrual rate. The daily interest rates to be used in calculating interest at the Highest Lawful Rate shall be determined by dividing the applicable Highest Lawful Rate per annum by the number of days in the calendar year for which such calculation is being made. None of the terms and provisions contained in this Agreement or in any other Loan Document which directly or indirectly relate to interest shall ever be construed without reference to this Section 2.23, or be construed to create a contract to pay for the use, forbearance or detention of money at an interest rate in excess of the Highest Lawful Rate. If the term of any Obligation is shortened by reason of acceleration of maturity as a result of any Default or by any other cause, or by reason of any required or permitted prepayment, and if for that (or any other) reason any Lender at any time, including but not limited to, the stated maturity, is owed or receives (and/or has received) interest in excess of interest calculated at the Highest Lawful Rate, then and in any such event all of any such excess interest shall be canceled automatically as of the date of such acceleration, prepayment or other event which produces the excess, and, if such excess interest has been paid to such Lender, it shall be credited pro tanto against the then-outstanding principal balance of the Borrower's obligations to such Lender, effective as of the date or dates when the event occurs which causes it to be excess interest, until such excess is exhausted or all of such principal has been fully paid and satisfied,

whichever occurs first, and any remaining balance of such excess shall be promptly refunded to its payor. Chapter 346 of the Texas Finance Code (which regulates certain revolving credit accounts (formerly Tex. Rev. Civ. Stat. ▇▇▇. Art. ▇▇▇▇, ▇▇. 15) shall not apply to this Agreement or to any Loan, nor shall this Agreement or any Loan be governed by or be subject to the provisions of such Chapter 346 in any manner whatsoever.

2.24 Interest Act (Canada). The parties acknowledge that some of the Mortgaged Properties are located in Canada. For purposes of the Interest Act (Canada), the annual rates of interest applicable to Eurodollar Loans are the rates as determined hereunder multiplied by that actual number of days in a period of one year commencing on the first day of the period for which such interest is payable and divided by 360.

ARTICLE III YIELD PROTECTION; TAXES

3.1 Yield Protection. If, on or after the date of this Agreement, the adoption of any law or any governmental or quasi-governmental rule, regulation, policy, guideline or directive (whether or not having the force of law), or any change in the interpretation or administration thereof by any governmental or quasi-governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Lender or applicable Lending Installation or the LC Issuer with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency:

(i) subjects any Lender or any applicable Lending Installation or the LC Issuer to any Taxes, or changes the basis of taxation of payments (other than with respect to Excluded Taxes) to any Lender in respect of its Eurodollar Loans or Letters of Credit or participations therein, or

(ii) imposes or increases or deems applicable any reserve, assessment, insurance charge, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender or any applicable Lending Installation or the LC Issuer (other than reserves and assessments taken into account in determining the interest rate applicable to Eurodollar Advances), or

(iii) imposes any other condition the result of which is to increase the cost to any Lender or any applicable Lending Installation or the LC Issuer of making, funding or maintaining its Eurodollar Loans or reduces any amount receivable by any Lender or any applicable Lending Installation in connection with its Eurodollar Loans and issue or participate in Letters of Credit, as the case may be, or requires any Lender or any applicable Lending Installation to make any payment calculated by reference to the amount of Eurodollar Loans or Letters of Credit or participations therein, held or interest or Letters of Credit fees received by it, by an amount deemed material by such Lender or the LC Issuer as the case may be, and the result of any of the foregoing is to increase the cost to such Lender or applicable Lending Installation of making or maintaining its Eurodollar Loans or Commitment or of issuing or participating in Letters of Credit or to reduce the return received by such Lender or applicable Lending Installation or the LC Issuer as the case may be, in connection with such Eurodollar Loans or Commitment or Letters of Credit or participations therein, then, within 15 days of demand by such Lender or the LC Issuer as the case may be, the Borrower shall pay such Lender or the LC Issuer as the case may be, such additional amount or amounts as will compensate such Lender or the LC Issuer as the case may be, for such increased cost or reduction in amount received.

3.2 Changes in Capital Adequacy Regulations. If a Lender or the LC Issuer determines the amount of capital required or expected to be maintained by such Lender or the LC Issuer, any Lending Installation of such Lender or the LC Issuer or any corporation controlling such Lender or the LC Issuer is increased as a result of a Change, then, within 15 days of demand by such Lender or the LC Issuer, the Borrower shall pay such Lender or the LC Issuer the amount necessary to compensate for

any shortfall in the rate of return on the portion of such increased capital which such Lender or the LC Issuer determines is attributable to this Agreement, its Revolving Exposure or its Commitment to make Loans and issue or participate in Letters of Credit, as the case may be, hereunder (after taking into account such Lender's or the LC Issuer's policies as to capital adequacy). "Change" means (i) any change after the date of this Agreement in the Risk-Based Capital Guidelines or (ii) any adoption of or change in any other law, governmental or quasi-governmental rule, regulation, policy, guideline, interpretation, or directive (whether or not having the force of law) after the date of this Agreement which affects the amount of capital required or expected to be maintained by any Lender or any Lending Installation or any corporation controlling any Lender. "Risk-Based Capital Guidelines" means (i) the risk-based capital guidelines in effect in the United States on the date of this Agreement, including transition rules, and (ii) the corresponding capital regulations promulgated by regulatory authorities outside the United States implementing the July 1988 report of the Basle Committee on Banking Regulation and Supervisory Practices Entitled "International Convergence of Capital Measurements and Capital Standards," including transition rules, and any amendments to such regulations adopted prior to the date of this Agreement.

3.3 Availability of Types of Advances. If any Lender determines that maintenance of its Eurodollar Loans at a suitable Lending Installation would violate any applicable law, rule, regulation, or directive, whether or not having the force of law, or if the Required Lenders determine that (i) deposits of a type and maturity appropriate to match fund Eurodollar Advances are not available or (ii) the interest rate applicable to Eurodollar Advances does not accurately reflect the cost of making or maintaining Eurodollar Advances, then the Agent shall suspend the availability of Eurodollar Advances and require any affected Eurodollar Advances to be repaid or converted to Floating Rate Advances, subject to the payment of any funding indemnification amounts required by Section 3.4.

3.4 Funding Indemnification. If any payment of a Eurodollar Advance occurs on a date which is not the last day of the applicable Interest Period, whether because of acceleration, prepayment or otherwise, or a Eurodollar Advance is not made on the date specified by the Borrower for any reason other than default by the Lenders, the Borrower will indemnify each Lender for any loss or cost incurred by it resulting therefrom, including, without limitation, any loss or cost in liquidating or employing deposits acquired to fund or maintain such Eurodollar Advance.

3.5 Taxes. (i) All payments by the Borrower to or for the account of any Lender, the LC Issuer or the Agent hereunder or under any Note or Letter of Credit application shall be made free and clear of and without deduction for any and all Taxes. If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder to any Lender, the LC Issuer or the Agent, (a) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 3.5) such Lender, the LC Issuer or the Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (b) the Borrower shall make such deductions, (c) the Borrower shall pay the full amount deducted to the relevant authority in accordance with applicable law and (d) the Borrower shall furnish to the Agent the original copy of a receipt evidencing payment thereof within 30 days after such payment is made.

(ii) In addition, the Borrower hereby agrees to pay any present or future stamp or documentary taxes and any other excise or property taxes, charges or similar levies which arise from any payment made hereunder or under any Note or Letter of Credit application or from the execution or delivery of, or otherwise with respect to, this Agreement or any Note or Letter of Credit application ("Other Taxes").

(iii) The Borrower hereby agrees to indemnify the Agent, the LC Issuer and each Lender for the full amount of Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes imposed on amounts payable under this Section 3.5) paid by the Agent, the LC Issuer or such

Lender and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto. Payments due under this indemnification shall be made within 30 days of the date the Agent or such Lender makes demand therefor pursuant to Section 3.6.

(iv) Each Lender that is not incorporated under the laws of the United States of America or a state thereof (each a "Non-U. S. Lender") agrees that it will, not less than ten Business Days after the date of this Agreement, (i) deliver to each of the Borrower and the Agent two duly completed copies of United States Internal Revenue Service Form 1001 or 4224, certifying in either case that such Lender is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes, and (ii) deliver to each of the Borrower and the Agent a United States Internal Revenue Form W-8 or W-9, as the case may be, and certify that it is entitled to an exemption from United States backup withholding tax. Each Non-U. S. Lender further undertakes to deliver to each of the Borrower and the Agent (x) renewals or additional copies of such form (or any successor form) on or before the date that such form expires or becomes obsolete, and (y) after the occurrence of any event requiring a change in the most recent forms so delivered by it, such additional forms or amendments thereto as may be reasonably requested by the Borrower or the Agent. All forms or amendments described in the preceding sentence shall certify that such Lender is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes, unless an event (including without limitation any change in treaty, law or regulation) has occurred prior to the date on which any such delivery would otherwise be required which renders all such forms inapplicable or which would prevent such Lender from duly completing and delivering any such form or amendment with respect to it and such Lender advises the Borrower and the Agent that it is not capable of receiving payments without any deduction or withholding of United States federal income tax.

(v) For any period during which a Non-U. S. Lender has failed to provide the Borrower with an appropriate form pursuant to clause (iv), above (unless such failure is due to a change in treaty, law or regulation, or any change in the interpretation or administration thereof by any governmental authority, occurring subsequent to the date on which a form originally was required to be provided), such Non-U. S. Lender shall not be entitled to indemnification under this Section 3.5 with respect to Taxes imposed by the United States; provided that, should a Non-U. S. Lender which is otherwise exempt from or subject to a reduced rate of withholding tax become subject to Taxes because of its failure to deliver a form required under clause (iv), above, the Borrower shall take such steps as such Non-U. S. Lender shall reasonably request to assist such Non-U. S. Lender to recover such Taxes.

(vi) Any Lender that is entitled to an exemption from or reduction of withholding tax with respect to payments under this Agreement or any Note pursuant to the law of any relevant jurisdiction or any treaty shall deliver to the Borrower (with a copy to the Agent), at the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law as will permit such payments to be made without withholding or at a reduced rate.

(vii) If the U.S. Internal Revenue Service or any other governmental authority of the United States or any other country or any political subdivision thereof asserts a claim that the Agent did not properly withhold tax from amounts paid to or for the account of any Lender (because the appropriate form was not delivered or properly completed, because such Lender failed to notify the Agent of a change in circumstances which rendered its exemption from withholding ineffective, or for any other reason), such Lender shall indemnify the Agent fully for all amounts paid, directly or indirectly, by the Agent as tax, withholding therefor, or otherwise, including penalties and interest, and including taxes imposed by any jurisdiction on amounts payable to the Agent under this subsection, together with all costs and expenses related thereto (including attorneys fees and

time charges of attorneys for the Agent, which attorneys may be employees of the Agent). The obligations of the Lenders under this Section 3.5(vii) shall survive the payment of the Obligations and termination of this Agreement.

3.6 Lender Statements: Survival of Indemnity. To the extent reasonably possible, each Lender shall designate an alternate Lending Installation with respect to its Eurodollar Loans to reduce any liability of the Borrower to such Lender under Sections 3.1, 3.2 and 3.5 or to avoid the unavailability of Eurodollar Advances under Section 3.3, so long as such designation is not, in the judgment of such Lender, disadvantageous to such Lender. Each Lender shall deliver a written statement of such Lender to the Borrower (with a copy to the Agent) as to the amount due, if any, under Section 3.1, 3.2, 3.4 or 3.5.

ARTICLE VIII ACCELERATIONS, WAIVERS, AMENDMENTS AND REMEDIES

8.1 Acceleration. (i) If any Default described in Section 7.6 or 7.7 occurs with respect to the Borrower, the obligations of the Lenders to make Loans hereunder and the obligation and power of the LC Issuer to issue Letters of Credit shall automatically terminate and the Obligations shall immediately become due and payable without any election or action on the part of the Agent, the LC Issuer or any Lender. If any other Default occurs, the Required Lenders (or the Agent with the consent of the Required Lenders) may terminate or suspend the obligations of the Lenders to make Loans hereunder, and the obligation and power of the LC Issuer to issue Letters of Credit, or declare the Obligations to be due and payable, or both, whereupon the Obligations shall become immediately due and payable, without presentment, demand, protest or notice of any kind, all of which the Borrower hereby expressly waives.

(ii) If within thirty (30) days after acceleration of the maturity of the Obligations or termination of the obligations of the Lenders to make Loans and the obligation and power of the LC Issuer to issue Letters of Credit hereunder as a result of any Default (other than any Default as described in Sections 7.6 or 7.7 with respect to the Borrower) and before any judgment or decree for the payment of the Obligations due shall have been obtained or entered, the required Lenders (in their sole discretion) shall so direct, the Agent shall, by notice to the Borrower, rescind and annul such acceleration and/or termination.

8.2 Amendments. Subject to the provisions of this Article VIII, the Required Lenders (or the Agent with the consent in writing of the Required Lenders) and the Borrower may enter into agreements supplemental hereto for the purpose of adding or modifying any provisions to the Loan Documents or changing in any manner the rights of the Lenders or the Borrower hereunder or waiving any Default hereunder; provided, however, that no such supplemental agreement shall, without the consent of all of the Lenders:

(i) Extend the final maturity of any Loan, or extend the expiry date of any Letter of Credit to a date after the Facility Termination Date or forgive all or any portion of the principal amount thereof or any reimbursement obligation of a Letter of Credit, or reduce the rate or extend the time of payment of interest or fees thereon or any reimbursement obligation of a Letter of Credit related thereto.

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

8.3 Preservation of Rights. No delay or omission of the Lenders, the LC Issuer or the Agent to exercise any right under the Loan Documents shall impair such right or be construed to be a waiver of any Default or an acquiescence therein, and the making of a Credit Extension notwithstanding the existence of a Default or the inability of the Borrower to satisfy the conditions precedent to such Credit Extension shall not constitute any waiver or acquiescence. Any single or partial exercise of any such right shall not preclude other or further exercise thereof or the exercise of any other right, and no waiver, amendment or other variation of the terms, conditions or provisions of the Loan Documents whatsoever shall be valid unless in writing signed by the Lenders required pursuant to Section 8.2, and then only to the extent in such writing specifically set forth.

9.10 Nonliability of Lenders. The relationship between the Borrower on the one hand and the Lenders, the LC Issuer and the Agent on the other hand shall be solely that of borrower and lender. Neither the Agent, the Arranger, the LC Issuer nor any Lender shall have any fiduciary responsibilities to the Borrower. Neither the Agent, the Arranger, the LC Issuer nor any Lender undertakes any responsibility to the Borrower to review or inform the Borrower of any matter in connection with any phase of the Borrower's business or operations. The Borrower agrees that neither the Agent, the Arranger nor any Lender shall have liability to the Borrower (whether sounding in tort, contract or otherwise) for losses suffered by the Borrower in connection with, arising out of, or in any way related to, the transactions contemplated and the relationship established by the Loan Documents, or any act, omission or event occurring in connection therewith, unless it is determined in a final non-appealable judgment by a court of competent jurisdiction that such losses resulted from the gross negligence or willful misconduct of the party from which recovery is sought. Neither the Agent, the Arranger, the LC Issuer nor any Lender shall have any liability with respect to, and the Borrower hereby waives, releases and agrees not to ▇▇▇ for, any special, indirect or consequential damages suffered by the Borrower in connection with, arising out of, or in any way related to the Loan Documents or the transactions contemplated thereby.

10.1 Appointment Nature of Relationship. Bank One is hereby appointed by each of the Lenders as its contractual representative (herein referred to as the "Agent") hereunder and under each other Loan Document, and each of the Lenders irrevocably authorizes the Agent to act as the contractual representative of such Lender with the rights and duties expressly set forth herein and in the other Loan Documents (the Agent may be referred to as the "Collateral Agent" in the other Loan Documents). The Agent agrees to act as such contractual representative upon the express conditions contained in this Article X. Notwithstanding the use of the defined term "Agent," it is expressly understood and agreed that the Agent shall not have any fiduciary responsibilities to any Lender by reason of this Agreement or any other Loan Document and that the Agent is merely acting as the contractual representative of the Lenders with only those duties as are expressly set forth in this Agreement and the other Loan Documents. In its capacity as the Lenders' contractual representative, the Agent (i) does not hereby assume any fiduciary duties to any of the Lenders, (ii) is a "representative" of the Lenders within the meaning of Section 9.102 of the Uniform Commercial Code and (iii) is acting as an independent contractor, the rights and duties of which are limited to those expressly set forth in this Agreement and the other Loan Documents.

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

10.3 General Immunity. Neither the Agent nor any of its directors, officers, agents or employees shall be liable to the Borrower, the Lenders or any Lender for any action taken or omitted to be taken by it or them hereunder or under any other Loan Document or in connection herewith or therewith except to the extent such action or inaction is determined in a final non-appealable judgment by a court of competent jurisdiction to have arisen from the gross negligence or willful misconduct of such Person.

10.4 No Responsibility for Loans, Recitals, etc. Neither the Agent nor any of its directors, officers, agents or employees shall be responsible for or have any duty to ascertain, inquire into, or verify (a) any statement, warranty or representation made in connection with any Loan Document or any borrowing hereunder, (b) the performance or observance of any of the covenants or agreements of any obligor under any Loan Document, including, without limitation, any agreement by an obligor to furnish information directly to each Lender; (c) the satisfaction of any condition specified in Article IV, except receipt of items required to be delivered solely to the Agent; (d) the existence or possible existence of any Default or Unmatured Default; (e) the validity, enforceability, effectiveness, sufficiency or genuineness of any Loan Document or any other instrument or writing furnished in connection therewith; (f) the value, sufficiency, creation, perfection or priority of any Lien in any collateral security; or (g) the financial condition of the Borrower or any guarantor of any of the Obligations or of any of the Borrower's or any such guarantor's respective Subsidiaries.

10.5 Action on Instructions of Lenders. The Agent shall in all cases be fully protected in acting, or in refraining from acting, hereunder and under any other Loan Document in accordance with written instructions signed by the Required Lenders, and such instructions and any action taken or failure to act pursuant thereto shall be binding on all of the Lenders. The Lenders hereby acknowledge that the Agent shall be under no duty to take any discretionary action permitted to be taken by it pursuant to the provisions of this Agreement or any other Loan Document unless it shall be requested in writing to do so by the Required Lenders. The Agent shall be fully justified in failing or refusing to take any action hereunder and under any other Loan Document unless it shall first be indemnified to its satisfaction by the Lenders pro rata against any and all liability, cost and expense that it may incur by reason of taking or continuing to take any such action.

10.6 Employment of Agents and Counsel. The Agent may execute any of its duties as Agent hereunder and under any other Loan Document by or through employees, agents, and attorneys-in-fact and shall not be answerable to the Lenders, except as to money or securities received by it or its authorized agents, for the default or misconduct of any such agents or attorneys-in-fact selected by it with reasonable care.

(including, without limitation, for any such amounts incurred by or asserted against the Agent in connection with any dispute between the Agent and any Lender or between two or more of the Lenders), or the enforcement of any of the terms of the Loan Documents or of any such other documents, provided that (i) no Lender shall be liable for any of the foregoing to the extent any of the foregoing is found in a final non-appealable judgment by a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of the Agent and (ii) any indemnification required pursuant to Section 3.5(vii) shall, notwithstanding the provisions of this Section 10.8, be paid by the relevant Lender in accordance with the provisions thereof. The obligations of the Lenders under this Section 10.8 shall survive payment of the Obligations and termination of this Agreement.

10.9 Notice of Default. The Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Unmatured Default hereunder unless the Agent has received written notice from a Lender or the Borrower referring to this Agreement describing such Default or Unmatured Default and stating that such notice is a "notice of default". In the event that the Agent receives such a notice, the Agent shall give prompt notice thereof to the Lenders.

10.10 Rights as a Lender. In the event the Agent is a Lender, the Agent shall have the same rights and powers hereunder and under any other Loan Document with respect to its Commitment and its Loans as any Lender and may exercise the same as though it were not the Agent, and the term "Lender" or "Lenders" shall, at any time when the Agent is a Lender, unless the context otherwise indicates, include the Agent in its individual capacity. The Agent and its Affiliates may accept deposits from, lend money to, and generally engage in any kind of trust, debt, equity or other transaction, in addition to those contemplated by this Agreement or any other Loan Document, with the Borrower or any of its Subsidiaries in which the Borrower or such Subsidiary is not restricted hereby from engaging with any other Person. The Agent, in its individual capacity, is not obligated to remain a Lender.

10.11 Lender Credit Decision. Each Lender acknowledges that it has, independently and without reliance upon the Agent, the Arranger or any other Lender and based on the financial statements prepared by the Borrower and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement and the other Loan Documents. Each Lender also acknowledges that it will, independently and without reliance upon the Agent, the Arranger or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement and the other Loan Documents.

10.12 Successor Agent. The Agent may resign at any time by giving written notice thereof to the Lenders and the Borrower, such resignation to be effective upon the appointment of a successor Agent or, if no successor Agent has been appointed, forty-five days after the retiring Agent gives notice of its intention to resign. The Agent may be removed at any time with or without cause by written notice received by the Agent from the Required Lenders, such removal to be effective on the date specified by the Required Lenders. Upon any such resignation or removal, the Required Lenders shall have the right to appoint, on behalf of the Borrower and the Lenders, a successor Agent. If no successor Agent shall have been so appointed by the Required Lenders within thirty days after the resigning Agents giving notice of its intention to resign, then the resigning Agent may appoint, on behalf of the Borrower and the Lenders, a successor Agent. Notwithstanding the previous sentence, the Agent may at any time without the consent of the Borrower or any Lender, appoint any of its Affiliates which is a commercial bank as a successor Agent hereunder. If the Agent has resigned or been removed and no successor Agent has been appointed, the Lenders may perform all the duties of the Agent hereunder and the Borrower shall make all payments in respect of the Obligations to the applicable Lender and for all other purposes shall deal directly with the Lenders. No successor Agent shall be deemed to be appointed hereunder until such successor Agent has accepted the appointment. Any such successor Agent shall be a commercial bank having capital and retained earnings of at least $100,000,000. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent

shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the resigning or removed Agent. Upon the effectiveness of the resignation or removal of the Agent, the resigning or removed Agent shall be discharged from its duties and obligations hereunder and under the Loan Documents. After the effectiveness of the resignation or removal of an Agent, the provisions of this Article X shall continue in effect for the benefit of such Agent in respect of any actions taken or omitted to be taken by it while it was acting as the Agent hereunder and under the other Loan Documents. In the event that there is a successor to the Agent by merger, or the Agent assigns its duties and obligations to an Affiliate pursuant to this Section 10.12, then the term "Alternate Base Rate" as used in this Agreement shall mean the prime rate, base rate or other analogous rate of the new Agent.

Any such Affiliate (and such Affiliate's directors, officers, agents and employees) which performs duties in connection with this Agreement shall be entitled to the same benefits of the indemnification, waiver and other protective provisions to which the Agent is entitled under Articles IX and X.

10.15 Execution of Loan Documents.

The Lenders hereby empower and authorize the Agent to execute and deliver to the Borrower on their behalf any agreements, documents or instruments as shall be necessary or appropriate to effect any releases of collateral which shall be permitted by the terms hereof or of any other Loan Document or which shall otherwise have been approved by the Required Lenders (or, if required by the terms of Section 8.2, all of the Lenders) in writing.

10.17 Co-Agents, Documentation Agent, Syndication Agent. Etc. Neither any of the Lenders identified in this Agreement as a "co-agent" nor the Documentation Agent or the Syndication Agent shall have any right, power, obligation, liability, responsibility or duty under this Agreement other than those applicable to all Lenders as such. Without limiting the foregoing, none of such Lenders shall have or be deemed to have a fiduciary relationship with any Lender. Each Lender hereby makes the same acknowledgments with respect to such Lenders as it makes with respect to the Agent in Section 10.11.

ARTICLE XI SET OFF: RATABLE PAYMENTS

11.1 Setoff. In addition to, and without limitation of, any rights of the Lenders under applicable law, if the Borrower becomes insolvent, however evidenced, or any Default occurs, any and all deposits (including all account balances, whether provisional or final and whether or not collected or available) and any other Indebtedness at any time held or owing by any Lender or any Affiliate of any Lender to or for the credit or account of the Borrower 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.

11.2 Ratable Payments. If any Lender, whether by setoff or otherwise, has payment made to it upon its total Revolving Exposure (other than payments received pursuant to Section 3.1, 3.2, 3.4 or 3.5) in a greater proportion than that received by any other Lender, such Lender agrees, promptly upon demand, to purchase a portion of the aggregate total Revolving Exposure held by the other

Lenders so that after such purchase each Lender will hold its Pro Rata Share of the aggregate total Revolving Exposure. If any Lender, whether in connection with setoff or amounts which might be subject to setoff or otherwise, receives collateral or other protection for its Obligations or such amounts which may be subject to setoff, such Lender agrees, promptly upon demand, to take such action necessary such that all Lenders share in the benefits of such collateral ratably in proportion to their respective Pro Rata Shares of the aggregate outstanding Revolving Exposure. In case any such payment is disturbed by legal process, or otherwise, appropriate further adjustments shall be made.

ARTICLE XII BENEFIT OF AGREEMENT; ASSIGNMENT; PARTICIPATIONS

12.1 Successors and Assigns. The terms and provisions of the Loan Documents shall be binding upon and inure to the benefit of the Borrower and the Lenders and their respective successors and assigns, except that (i) the Borrower shall not have the right to assign its rights or obligations under the Loan Documents and (ii) any assignment by any Lender must be made in compliance with Section 12.3. The parties to this Agreement acknowledge that clause (ii) of this Section 12.1 relates only to absolute assignments and does not prohibit assignments creating security interests, including, without limitation, any pledge or assignment by any Lender of all or any portion of its rights under this Agreement and any Note to a Federal Reserve Bank; provided, however, that no such pledge or assignment creating a security interest shall release the transferor Lender from its obligations hereunder unless and until the parties thereto have complied with the provisions of Section 12.3. The Agent may treat the Person which made any Loan or which holds any Note as the owner thereof for all purposes hereof unless and until such Person complies with Section 12.3; provided, however, that the Agent may in its discretion (but shall not be required to) follow instructions from the Person which made any Loan or which holds any Note to direct payments relating to such Loan or Note to another Person. Any assignee of the rights to any Loan or any Note agrees by acceptance of such assignment to be bound by all the terms and provisions of the Loan Documents. Any request, authority or consent of any Person, who at the time of making such request or giving such authority or consent is the owner of the rights to any Loan or Note, shall be conclusive and binding on any subsequent holder or assignee of the rights to such Loan or Note.

12.2 Participations.

(i) Permitted Participants: Effect. Any Lender may, at any time sell to one or more banks or other entities ("Participants") participating interests in any Revolving Exposure owing to such Lender, any Note held by such Lender, any Commitment of such Lender or any other interest of such Lender under the Loan Documents. In the event of any such sale by a Lender of participating interests to a Participant, such Lender's obligations under the Loan Documents shall remain unchanged, such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, such Lender shall remain the owner of its Revolving Exposure and the holder of any Note issued to it in evidence thereof for all purposes under the Loan Documents, all amounts payable by the Borrower under this Agreement shall be determined as if such Lender had not sold such participating interests, and the Borrower and the Agent shall continue to deal solely and directly with such Lender in connection with such Lender's rights and obligations under the Loan Documents.

(ii) Voting Rights. Each Lender shall retain the sole right to approve, without the consent of any Participant, any amendment, modification or waiver of any provision of the Loan Documents other than any amendment, modification or waiver with respect to any Credit Extension or Commitment in which such Participant has an interest which forgives principal, interest or fees or reduces the interest rate or fees payable with respect to any such Loan or Commitment, extends the Facility Termination Date, postpones any date fixed for any regularly-scheduled payment of principal of, or interest or fees on, any such Loan or Commitment, releases any guarantor of any such Loan or releases all or substantially all of the collateral, if any, securing any such Loan.

(iii) Benefit of Setoff. The Borrower agrees that each Participant shall be deemed to have the right of setoff provided in Section 11. 1 in respect of its participating interest in amounts owing under the Loan Documents to the same extent as if the amount of its participating interest were owing directly to it as a Lender under the Loan Documents, provided that each Lender shall retain the right of setoff provided in Section 11 .1 with respect to the amount of participating interests sold to each Participant. The Lenders agree to share with each Participant, and each Participant, by exercising the right of setoff provided in Section 11 .1, agrees to share with each Lender, any amount received pursuant to the exercise of its right of setoff, such amounts to be shared in accordance with Section 11.2 as if each Participant were a Lender.

12.3 Assignments.

(i) Permitted Assignments. Any Lender may, 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. Such assignment shall be substantially in the form of Exhibit C or in such other form as may be agreed to by the parties thereto. The consent of the Borrower and the Agent and the LC Issuer shall be required prior to an assignment becoming effective with respect to a Purchaser which is not a Lender or an Affiliate thereof, provided, however, that if a Default has occurred and is continuing, the consent of the Borrower shall not be required. Such consent shall not be unreasonably withheld or delayed. Each such assignment with respect to a Purchaser which is not a Lender or an Affiliate thereof shall (unless each of the Borrower and the Agent otherwise consents) be in an amount not less than the lesser of (i) $5,000,000 or (ii) the remaining amount of the assigning Lender's Commitment (calculated as at the date of such assignment) or outstanding Loans (if the applicable Commitment has been terminated).

(ii) Effect: Effective Date. Upon (i) delivery to the Agent of an assignment, together with any consents required by Section 12.3.1, and (ii) payment of a $4,000 fee to the Agent for processing such assignment (unless such fee is waived by the Agent), such assignment shall become effective on the effective date specified in such assignment. The assignment shall contain a representation by the Purchaser to the effect that none of the consideration used to make the purchase of the Commitment and Revolving Exposure under the applicable assignment agreement constitutes "plan assets" as defined under ERISA and that the rights and interests of the Purchaser in and under the Loan Documents will not be "plan assets" under ERISA. 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 or on behalf of the Lenders and shall have all the rights and obligations of a Lender under the Loan Documents, to the same extent as if it were an original party hereto, and no further consent or action by the Borrower, the Lenders or the Agent shall be required to release the transferor Lender with respect to the percentage of the Aggregate Commitment and Revolving Exposure assigned to such Purchaser. Upon the consummation of any assignment to a Purchaser pursuant to this Section 12.3.2, the transferor Lender, the Agent and the Borrower shall make appropriate arrangements so that new Notes or, as appropriate, replacement Notes are issued to such transferor Lender and new Notes or, as appropriate, replacement Notes, are issued to such Purchaser, in each case in principal amounts reflecting their respective Commitments, as adjusted pursuant to such assignment.

12.4 Dissemination of Information. The Borrower authorizes each Lender 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 Lender's possession concerning the creditworthiness of the Borrower and its Subsidiaries, including without limitation any information contained in any Reports; provided that each Transferee and prospective Transferee agrees to be bound by Section 9.11 of this Agreement.

12.5 Tax Treatment. If any interest in any Loan Document is transferred to any Transferee which is organized under the laws of any jurisdiction other than the United States or any State thereof, the

transferor Lender shall cause such Transferee, concurrently with the effectiveness of such transfer, to comply with the provisions of Section 3.5(iv).

ARTICLE XIII NOTICES

Except as otherwise permitted by Section 2.14 with respect to borrowing notices, all notices, requests and other communications to any party hereunder shall be in writing (including electronic transmission, facsimile transmission or similar writing) and shall be given to such party: (x) in the case of the Borrower or the Agent, at its address or facsimile number set forth on the signature pages hereof, (y) in the case of any Lender, at its address or facsimile number set forth in its administrative questionnaire or (z) in the case of any party, at such other address or facsimile number as such party may hereafter specify for the purpose by notice to the Agent and the Borrower in accordance with the provisions of this Section 13.1.

ARTICLE XV CHOICE OF LAW: CONSENT TO JURISDICTION: WAIVER OF JURY TRIAL

If requested to do so by any party, each party hereto agrees to waive service of process and to execute any and all documents necessary to implement such waiver in accordance with the Texas Rules of Civil Procedure.

(b) The parties recognize that courts outside of Dallas County, Texas, may also have jurisdiction over suits, actions or proceedings arising out of this Agreement and the Loan Documents. Except for proceedings brought by the Agent and/or the Lenders in those jurisdictions where the Mortgaged Properties are located, in the event any party shall institute a proceeding involving this Agreement or the Loan Documents in a jurisdiction outside Dallas County, Texas, the party instituting such litigation shall indemnify the other parties for any losses and expenses that may result from the breach of the foregoing covenant to institute such proceeding only in a state or federal court in Dallas County, Texas, including without limitation any additional expenses incurred as the result of litigating in another jurisdiction, such as the expenses and reasonable fees of local counsel and travel and lodging expenses of the indemnified parties, its witnesses, experts and support personnel.

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

FORM OF OPINION

As of April 12, 2002

The Agent, the Lenders who are parties to the
Credit Agreement described below, and Montreal
Trust Company of Canada.

Gentlemen/Ladies:

We are counsel for Equity Oil Company (the "Borrower"), and have represented the Borrower in connection with its execution and delivery of a Credit Agreement dated as of April 12, 2002 (the "Agreement") among the Borrower, the Lenders named therein, and Bank One, NA, as Agent, and providing for Advances in an aggregate principal amount not exceeding $75,000,000 at any one time outstanding. All capitalized terms used in this opinion and not otherwise defined herein shall have the meanings attributed to them in the Agreement.

We have examined the Borrower's **[describe constitutive documents of Borrower and appropriate evidence of authority to enter into the transaction] * *, the Loan Documents and such other matters of fact and law which we deem necessary in order to render this opinion. Based upon the foregoing, it is our opinion that:

1. Each of the Borrower and its Subsidiaries is a corporation, partnership or limited liability company duly and properly incorporated or organized, as the case may be, validly existing and (to the extent such concept applies to such entity) in good standing under the laws of its jurisdiction of incorporation or organization and has all requisite authority to conduct its business in each jurisdiction in which its business is conducted.

2. The execution and delivery by the Borrower of the Loan Documents to which it is a party and the performance by the Borrower of its obligations thereunder have been duly authorized by proper corporate proceedings on the part of the Borrower and will not:

(a) require any consent of the Borrower's shareholders or members (other than any such consent as has already been given and remains in full force and effect);

(b) violate (i) any law, rule, regulation, order, writ, judgment, injunction, decree or award binding on the Borrower or any of its Subsidiaries or (ii) the Borrower's or any Subsidiary's articles or certificate of incorporation, partnership agreement, certificate of partnership, articles or certificate of organization, by-laws, or operating or other management agreement, as the case may be, or (iii) the provisions of any indenture, instrument or agreement to which the Borrower or any of its Subsidiaries is a party or is subject, or by which it, or its Property, is bound, or conflict with or constitute a default thereunder; or

(c) result in, or require, the creation or imposition of any Lien in, of or on the Property of the Borrower or a Subsidiary pursuant to the terms of any indenture, instrument or agreement binding upon the Borrower or any of its Subsidiaries.

3. The Loan Documents to which the Borrower is a party have been duly executed and delivered by the Borrower and constitute legal, valid and binding obligations of the Borrower enforceable against the Borrower in accordance with their terms except to the extent the enforcement thereof may be limited by bankruptcy, insolvency or similar laws affecting the enforcement of creditors' rights generally and subject also to the availability of equitable remedies if equitable remedies are sought.

4. The Loan Documents to which each Subsidiary is a party have been duly executed and delivered by such Subsidiary and constitute legal, valid and binding obligations of such Subsidiary and forcible against such Subsidiary in accordance with their terms, except to the extent that the

enforcement thereof may be limited by bankruptcy, insolvency or similar laws affecting the enforcement of creditors' rights generally and subject also to the availability of equitable remedies if equitable remedies are sought.

5. There is no litigation, arbitration, governmental investigation, proceeding or inquiry pending or, to the best of our knowledge after due inquiry, threatened against the Borrower or any of its Subsidiaries which, if adversely determined, could reasonably be expected to have a Material Adverse Effect.

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

This opinion may be relied upon by the Agent, the Lenders and their participants, assignees and other transferees.

Very truly yours,
