Subject to the terms and conditions hereof, and the terms and conditions of the Loan Documents as hereafter defined, each Bank agrees to amend and restate its extension of credit to the Borrower to the extent of its Pro Rata Part and the Borrower agrees to such amendment and restatement of its extension of credit from the Banks (the "Term Loan"), in the maximum principal amount of Twenty Four Million Three Hundred Thousand and No/100 Dollars ($24,300,000.00). This amount represents the outstanding principal indebtedness of the Former Term Notes and shall be evidenced by the Term Notes. The proceeds of the Term Notes shall refinance and be a continuation of a portion of the outstanding indebtedness evidenced by the Former Term Notes. The obligation of the Borrowers hereunder shall be evidenced by this Agreement and the Term Notes issued in connection herewith, said Term Notes to be as described in Section 3.1 hereof. 2.2 Terms of Revolving Commitment. Subject to the terms and conditions hereof, and the terms and conditions of the Loan Documents as hereafter defined, each Bank agrees severally to make Advances to the Borrowers from time to time during the period beginning on the Effective Date and ending on the Revolving Maturity Date in such amounts as the Borrowers may request up to an amount not to exceed, in the aggregate principal amount outstanding at any time, the Revolving Commitment. The obligation of the Borrowers hereunder shall be evidenced by this Agreement and the Revolving Notes issued in connection herewith, said Revolving Notes to be as described in Section 3.2 hereof. Notwithstanding any other provision of this Agreement, no Advance shall be required to be made hereunder if any Event of Default (as hereinafter defined) has occurred and is continuing or if any event or condition has occurred or failed to occur which with the passage of time or service of notice, or both, would constitute an Event of Default. Each Advance under the Revolving Commitment shall be an aggregate amount of at least $100,000 or a whole number multiple thereof except an Advance of the entire remaining unborrowed Revolving Commitment. Irrespective of the face amount of the Revolving Note or Notes, the Banks shall never have the obligation to Advance any amount or amounts in excess of the Available Commitment or to increase the Revolving Commitment. The total number of Tranches under the Revolving Commitment which may be outstanding at any time hereunder shall never exceed five (5), whether such Tranches are Prime Rate Loans, LIBOR Loans, or a combination thereof. Within the limit of each Bank's Revolving Commitment, the Borrowers may borrow, repay and reborrow under this Section 2 prior to the Revolving Maturity Date. 2.3 Procedure for Borrowing. Whenever the Borrowers desire an Advance hereunder, they shall give Agent telegraphic, telex, facsimile or telephonic notice ("Notice of Borrowing") of such requested Advance, which in the case of telephonic notice, shall be promptly confirmed in writing. Each Notice of Borrowing shall be in the form of Exhibit "A" attached hereto and shall be received by Agent not later than 11:00 a.m. Oklahoma City, Oklahoma time, (i) one Business Day prior to the Borrowing Date in the case of the Prime Rate Loan, or (ii) two London Business Days prior to any proposed Borrowing Date in the case of LIBOR Loans. Each Notice of Borrowing shall specify (i) the Borrowing Date (which, if at Prime Rate Loan, shall be a Business Day and if a LIBOR Loan, a London Business Day), (ii) the principal amount to be borrowed, (iii) the portion of the Advance constituting Prime Rate Loans and/or LIBOR Loans and (iv) if any portion of the proposed Advance is to constitute LIBOR Loans, the initial Interest Period selected by Borrowers pursuant to Section 4 hereof to be applicable thereto. Upon receipt of such Notice, Agent shall advise each Bank thereof; provided, that if the Banks have received at least one (1) day's notice of such Advance prior to funding of a Prime Rate Loan, or at least two (2) days' notice of each Advance prior to funding in the case of a LIBOR Loan, each Bank shall provide Agent at its office at 501 N.W. Grand Blvd., Oklahoma City, Oklahoma 73118, not later than 1:00 p.m., Oklahoma City, Oklahoma time, on the Borrowing Date, in immediately available funds, its pro rata share of the requested Advance, but the aggregate of all such fundings by each Bank shall never exceed such Bank's Revolving Commitment. Not later than 2:00 p.m., Oklahoma City, Oklahoma time, on the Borrowing Date, Agent shall make available to the Borrowers at the same office, in like funds, the aggregate amount of such requested Advance. Neither Agent nor any Bank shall incur any liability to the Borrowers in acting upon any Notice of Borrowing which Agent or such Bank believes in good faith to have been given by a duly authorized officer or other person authorized to borrow on behalf of Borrowers or for otherwise acting in good faith under this Section 2.3 . Upon funding of Advances by Banks in accordance with this Agreement, pursuant to any such Notice, the Borrowers shall have effected Advances hereunder. 2.4 Letters of Credit. On the terms and conditions hereinafter set forth, the Agent shall from time to time during the period beginning on the Effective Date and ending on the Revolving Maturity Date upon request of Borrowers issue standby and/or commercial Letters of Credit for the account of Borrowers (the "Letters of Credit") in such face amounts as Borrowers may request, but not to exceed in the aggregate face amount at any time outstanding the sum of Two Million Dollars ($2,000,000.00). The face amount of all Letters of Credit issued and outstanding hereunder shall be considered as Advances for Borrowing Base purposes and all payments made by the Agent on such Letters of Credit shall be considered as Advances under the Revolving Notes. Each Letter of Credit issued for the account of Borrowers hereunder shall (i) be in favor of such beneficiaries as specifically requested by Borrowers, (ii) have an expiration date not exceeding one year from the Revolving Maturity Date, and (iii) contain such other terms and provisions as may be reasonably required by Bank. Each Bank (other than Agent) agrees that, upon issuance of any Letter of Credit hereunder, it shall automatically acquire a participation in the Agent's liability under such Letter of Credit in an amount equal to such Bank's Revolving Commitment Percentage of such liability, and each Bank (other than Agent) thereby shall absolutely, unconditionally and irrevocably assume, as primary obligor and not as surety, and shall be unconditionally obligated to Agent to pay and discharge when due, its Revolving Commitment Percentage of Agent's liability under such Letter of Credit. The Borrowers hereby unconditionally agree to pay and reimburse the Agent for the amount of each demand for payment under any Letter of Credit that is in substantial compliance with the provisions of any such Letter of Credit at or prior to the date on which payment is to be made by the Agent to the beneficiary thereunder, without presentment, demand, protest or other formalities of any kind. Upon receipt from any beneficiary of any Letter of Credit of any demand for payment under such Letter of Credit, the Agent shall promptly notify the Borrowers of the demand and the date upon which such payment is to be made by the Agent to such beneficiary in respect of such demand. Forthwith upon receipt of such notice from the Agent, Borrowers shall advise the Agent whether or not they intend to borrow hereunder to finance their obligations to reimburse the Agent, and if so, submit a Notice of Borrowing as provided in Section 2.3 hereof. If Borrowers fail to so advise Agent and thereafter fail to reimburse Agent, the Agent shall notify each Bank of the demand and the failure of the Borrowers to reimburse the Agent, and each Bank shall reimburse the Agent for its Revolving Commitment Percentage of each such draw paid by the Agent and unreimbursed by the Borrowers. All such amounts paid by Agent and/or reimbursed by the Banks shall be treated as an Advance or Advances under the Revolving Commitment, which Advances shall be immediately due and payable and shall bear interest at the Default Rate. 2.5 Procedure for Obtaining Letters of Credit. The amount and date of issuance, renewal, extension or reissuance of a Letter of Credit pursuant to the Banks' commitment above in Section 2.4 shall be designated by Borrowers' written request delivered to Agent at least three (3) Business Days prior to the date of such issuance, renewal, extension or reissuance. Concurrently with or promptly following the delivery of the request for a Letter of Credit, Borrowers shall execute and deliver to the Agent an application and agreement with respect to the Letters of Credit, said application and agreement to be in the form used by the Agent. The Agent shall not be obligated to issue, renew, extend or reissue such Letters of Credit if (A) the amount thereon when added to the face amount of all outstanding Letters of Credit plus any Reimbursement Obligations exceeds Two Million Dollars ($2,000,000.00) or (B) the amount thereof when added to the Revolving Loans outstanding would exceed the Available Commitment. Borrowers agree to pay the Agent for the benefit of the Banks the following commissions and fees for issuing the Letters of Credit (calculated separately for each Letter of Credit): a fee in an amount equal to the greater of: (i) one percent (1%) per annum on the maximum face amount of the Letter of Credit due quarterly in arrears computed on a basis of a year containing 360 days or (ii) $500.00. Borrowers further agree to pay Agent an additional fronting fee equal to one-eighth of one percent (.125%) per annum on the maximum face amount of each Letter of Credit due and payable at the time the Letter of Credit is issued. Borrowers hereby agree to pay such other amounts as are customary for letter of credit as are published by Agent from time to time. Such commissions shall be payable prior to the issuance of each Letter of Credit and thereafter on each anniversary date of such issuance while such Letter of Credit is outstanding. 2.6 Voluntary Reduction of Revolving Commitment. The Borrowers may at any time, or from time to time, upon not less than three (3) Business Days' prior written notice to Agent, reduce or terminate the Revolving Commitment; provided, however, that (i) each reduction in the Revolving Commitment must be in the amount of $500,000 or more, in increments of $100,000 and (ii) each reduction must be accompanied by a prepayment of the Revolving Notes in the amount by which the outstanding principal balance of the Revolving Notes exceeds the Revolving Commitment as reduced pursuant to this Section 2. 2.7 Commitment Reductions. The Borrowing Base shall be reduced from time to time in accordance with Section 7.2 hereof. If, as a result of any such reduction in the Borrowing Base, the Total Outstandings ever exceed the Borrowing Base then in effect, the Borrowers shall make the mandatory prepayment of principal required pursuant to Section 9.2 hereof. 2.8 Several Obligations. The obligations of the Banks under the Revolving Commitment and pursuant to the Term Commitment are several and not joint. The failure of any Bank to make an Advance required to be made by it shall not relieve any other Bank of its obligation to make its Advance, and no Bank shall be responsible for the failure of any other Bank to make the Advance to be made by such other Bank. 3. Notes Evidencing Loans. The loans described above in Section 2 shall be evidenced by promissory notes of Borrowers as follows: 3.1 Form of Term Notes. The Term Loan shall be evidenced by the Term Notes in the aggregate face amount of $24,300,000, and shall be in the form of Exhibit "B-2" hereto with appropriate insertions (each a "Term Note"). Although the Term Notes may be dated as of the Effective Date, interest in respect thereof shall be payable only for the period during which the loans evidenced thereby are outstanding and, although the stated amount of the Term Notes may be higher, the Term Notes shall be enforceable, with respect to Borrowers' obligation to pay the principal amount thereof, only to the extent of the unpaid principal amount of the loans. Banks shall have no obligation to advance any additional funds pursuant to the Term Loan or Term Notes. 3.2 Form of Revolving Notes. The Revolving Loan shall be evidenced by a Note or Notes in the aggregate face amount of $45,700,000, and shall be in the form of Exhibit "B-1" hereto with appropriate insertions (each a "Revolving Note"). Notwithstanding the face amount of the Revolving Notes, the actual principal amount due from the Borrowers to Banks on account of the Revolving Notes, as of any date of computation, shall be the sum of Advances then and theretofore made on account thereof, less all principal payments actually received by Banks in collected funds with respect thereto. Although the Revolving Notes may be dated as of the Effective Date, interest in respect thereof shall be payable only for the period during which the loans evidenced thereby are outstanding and, although the stated amount of the Revolving Notes may be higher, the Revolving Notes shall be enforceable, with respect to Borrowers' obligation to pay the principal amount thereof, only to the extent of the unpaid principal amount of the loans. Irrespective of the face amount of the Revolving Notes, no Bank shall ever be obligated to advance on the Revolving Commitment any amount in excess of its Revolving Commitment then in effect. 3.3 Issuance of Additional Notes. From time to time new Notes may be issued to other Banks as such Banks become parties to this Agreement. Upon request from Agent, the Borrowers shall execute and deliver to Agent any such new or additional Notes. From time to time as new Notes are issued the Agent shall require that each Bank exchange their Notes for newly issued Notes to better reflect the extent of each Bank's Commitment hereunder. The notes replaced shall be marked to indicate that they have been replaced and/or returned to the Borrowers. 3.4 Interest Rates. The unpaid principal balance of the Notes shall bear interest from time to time as set forth in Section 4 hereof. 3.5 Payment of Interest. Interest on the Notes shall be payable on each Interest Payment Date. 3.6 Payment of Principal. 3.6.1 Beginning March 31,2002, and continuing on or before the last day of each calendar quarter thereafter through the Term Maturity Date, Borrower shall, in addition to the payment of interest required pursuant to Section 3.5 above, make a payment of principal on the Term Notes for the ratable benefit of the Banks in the amount of $1,350,000.00. All outstanding principal plus all accrued but unpaid interest due on the Term Notes shall be due and payable in full on the Term Maturity Date. 3.6.2 Principal of the Revolving Notes shall be due and payable to the Agent for the ratable benefit of the Banks on the Revolving Maturity Date unless earlier due in whole or in part as a result of an acceleration of the amount due or pursuant to the mandatory prepayment provisions of Section 9.2 hereof. 3.7 Payment to Banks. Each Bank's Pro Rata Part of each payment or prepayment of the Loans shall be directed by wire transfer to such Bank by the Agent at the address provided to the Agent for such Bank for payments no later than 2:00 p.m., Oklahoma City, Oklahoma, time on the Business Day such payments or prepayments are deemed hereunder to have been received by Agent; provided, however, in the event that any Bank shall have failed to make an Advance as contemplated under Section 2 hereof (a "Defaulting Bank") and the Agent or another Bank or Banks shall have made such Advance, payment received by Agent for the account of such Defaulting Bank or Banks shall not be distributed to such Defaulting Bank or Banks until such Advance or Advances shall have been repaid in full to the Bank or Banks who funded such Advance or Advances. Any payment or prepayment received by Agent at any time after 12:00 noon, Oklahoma City, Oklahoma, time on a Business Day shall be deemed to have been received on the next Business Day. Interest shall cease to accrue on any principal as of the end of the day preceding the Business Day on which any such payment or prepayment is deemed hereunder to have been received by Agent. If Agent fails to transfer any principal amount to any Bank as provided above, then Agent shall promptly direct such principal amount by wire transfer to such Bank. 3.8 Sharing of Payments, Etc. If any Bank shall obtain any payment (whether voluntary, involuntary, or otherwise) on account of the Loans, (including, without limitation, any set-off) which is in excess of its Pro Rata Part of payments on either of the Loans, as the case may be, obtained by all Banks, such Bank shall purchase from the other Banks such participation as shall be necessary to cause such purchasing Bank to share the excess payment pro rata with each of them; provided that, if all or any portion of such excess payment is thereafter recovered from such purchasing Bank, the purchase shall be rescinded and the purchase price restored to the extent of the recovery. The Borrowers agree that any Bank so purchasing a participation from another Bank pursuant to this Section may, to the fullest extent permitted by law, exercise all of its rights of payment (including the right of offset) with respect to such participation as fully as if such Bank were the direct creditor of the Borrowers in the amount of such participation. 3.9 Non-Receipt of Funds by the Agent. Unless the Agent shall have been notified by a Bank or the Borrowers (the "Payor") prior to the date on which such Bank is to make payment to the Agent of the proceeds of a Loan to be made by it hereunder or the Borrowers are to make a payment to the Agent for the account of one or more of the Banks, as the case may be (such payment being herein called the "Required Payment"), which notice shall be effective upon receipt, that the Payor does not intend to make the Required Payment to the Agent, the Agent may assume that the Required Payment has been made and may, in reliance upon such assumption (but shall not be required to), make the amount thereof available to the intended recipient on such date and, if the Payor has not in fact made the Required Payment to the Agent, the recipient of such payment shall, on demand, pay to the Agent the amount made available to it together with interest thereon in respect of the period commencing on the date such amount was made available by the Agent until the date the Agent recovers such amount at the rate applicable to such portion of the applicable Loan. 3.10 Capital Adequacy. If either (i) the introduction or implementation of or the compliance with or any change in or in the interpretation of any law, rule or regulation or (ii) the introduction or implementation of or the compliance with any mandatory request, directive or guideline from any central bank or other governmental authority (whether or not having the force of law) affects or would affect the amount of capital required or expected to be maintained by any Bank or any corporation controlling any Bank as a result of maintaining its Pro Rata Part of the Revolving Commitment, then within fifteen (15) days after demand by such Bank, the Borrowers will pay to such Bank, from time to time as specified by such Bank, such additional amount or amounts which such Bank shall reasonably determine to be appropriate to compensate such Bank or any corporation controlling such Bank in light of such circumstances, to the extent that such Bank reasonably determines that the amount of any such capital would be increased, or the rate of return on any such capital would be reduced in whole or in part, based on the existence of the amount of the Loans or such Bank's Revolving Commitment under this Agreement; provided, however, that to the extent such notice is given by any such Bank more than 180 days after the occurrence of the event giving rise to the additional costs of the type described in this Section, such Bank shall not be entitled to compensation pursuant to this Section for any amounts incurred or accruing prior to the date 180 days before the giving of such notice, except to the extent such law, rule, regulation, request, directive or guideline shall have been given retroactive effective affecting a period beginning more than 180 days prior to such notice. 4. Interest Rates. 4.1 Options. 4.1.1 Prime Rate Loans. On Prime Rate Loans the Borrowers agree to pay interest on the Notes calculated on the basis of the actual days elapsed in a year consisting of 360 days with respect to the unpaid principal amount of each Prime Rate Loan from the date the proceeds thereof are advanced to Borrowers until maturity (whether by acceleration or otherwise), at a varying rate per annum equal to the lesser of (i) the Maximum Rate, or (ii) the sum of the Prime Rate plus the Prime Rate Margin. Subject to the provisions of this Agreement as to prepayment, the principal of the Notes representing Prime Rate Loans shall be payable as specified in Section 3.6 hereof and the interest in respect of each Prime Rate Loan shall be payable on each Interest Payment Date. Past due principal and, to the extent permitted by law, past due interest in respect to each Prime Rate Loan, shall bear interest, payable on demand, at a rate per annum equal to the Default Rate 4.1.2 LIBOR Loans. On LIBOR Loans the Borrowers agree to pay interest calculated on the basis of a year consisting of 360 days with respect to the unpaid principal amount of each LIBOR Loan from the date the proceeds thereof are advanced to Borrowers until maturity (whether by acceleration or otherwise), at a varying rate per annum equal to the lesser of (i) the Maximum Rate, or (ii) the LIBOR Rate plus the LIBOR Margin. Subject to the provisions of this Agreement with respect to prepayment, the principal of the Notes shall be payable as specified in Section 3.6 hereof and the interest with respect to each LIBOR Loan shall be payable on each Interest Payment Date. Past due principal and, to the extent permitted by law, past due interest shall bear interest, payable on demand, at a rate per annum equal to the Default Rate. Upon three (3) London Business Days' written notice prior to the making by the Banks of any LIBOR Loan (in the case of the initial Interest Period therefor) or the expiration date of each succeeding Interest Period (in the case of subsequent Interest Periods therefor), Borrowers shall have the option, subject to compliance by Borrowers with all of the provisions of this Agreement, as long as no Event of Default exists, to specify whether the Interest Period commencing on any such date shall be a one (1), two (2), three (3) or six (6) month period. If Agent shall not have received timely notice of a designation of such Interest Period as herein provided, Borrowers shall be deemed to have elected to convert all maturing LIBOR Loans to Prime Rate Loans. 4.2 Interest Rate Determination. The Leverage Ratio shall be determined as of the end of each fiscal quarter of the Borrowers' fiscal year based upon the Borrowers' financial statements delivered pursuant to Section 12.1.2 below. Each change in the Prime Rate Margin and the LIBOR Margin resulting from a change in the Leverage Ratio shall be effective during the period commencing on and including the date of delivery to the Agent of such financial statements indicating such change and ending on the date immediately preceding the effective date of the next change. Agent shall determine each interest rate applicable to the Loans hereunder in accordance with the provisions of this Agreement. The Agent shall give prompt notice to the Borrowers and the Banks of each rate of interest so determined and its determination thereof shall be conclusive absent error. 4.3 Conversion Option. Borrowers may elect from time to time (i) to convert all or any part of its LIBOR Loans to Prime Rate Loans by giving Agent irrevocable notice of such election in writing prior to 10:00 a.m. (Oklahoma City, Oklahoma time) on the conversion date and such conversion shall be made on the requested conversion date, provided that any such conversion of a LIBOR Loan shall only be made on the last day of the LIBOR Interest Period with respect thereof, (ii) to convert all or any part of its Prime Rate Loans to LIBOR Loans by giving the Agent irrevocable written notice of such election three (3) London Business Days prior to the proposed conversion and such conversion shall be made on the requested conversion date or, if such requested conversion date is not a London Business Day or a Business Day, as the case may be, on the next succeeding London Business Day or Business Day, as the case may be. Any such conversion shall not be deemed to be a prepayment of any of the loans for purposes of this Agreement or the Notes. 4.4 Recoupment. If at any time the applicable rate of interest selected pursuant to Sections 4.1.1 or 4.1.2 above shall exceed the Maximum Rate, thereby causing the interest on the Notes to be limited to the Maximum Rate, then any subsequent reduction in the interest rate so selected or subsequently selected shall not reduce the rate of interest on the Notes below the Maximum Rate until the total amount of interest accrued on the Note equals the amount of interest which would have accrued on the Notes if the rate or rates selected pursuant to Sections 4.1.1 or 4.1.2, as the case may be, had at all times been in effect. 5. Change of Circumstances. 5.1 Unavailability of Funds or Inadequacy of Pricing. In the event that, in connection with any proposed LIBOR Loan, the Agent determines, which determination shall, absent manifest error, be final, conclusive and binding upon all parties, due to changes in circumstances since the date hereof, adequate and fair means do not exist for determining the LIBOR Rate or such rate will not accurately reflect the costs to the Banks of funding LIBOR Loans for such LIBOR Interest Period, the Agent shall give notice of such determination to the Borrowers and the Banks, whereupon, until the Agent notifies the Borrowers and the Banks that the circumstances giving rise to such suspension no longer exist, the obligations of the Banks to make, continue or convert Loans into LIBOR Loans shall be suspended, and all loans to Borrowers shall be Prime Rate Loans during the period of suspension. 5.2 Change in Laws. If at any time any new law or any change in existing laws or in the interpretation of any new or existing laws shall make it unlawful for any Bank to make or continue to maintain or fund LIBOR Loans hereunder, then such Bank shall promptly notify Borrowers in writing and such Bank's obligation to make, continue or convert Loans into LIBOR Loans under this Agreement shall be suspended until it is no longer unlawful for such Bank to make or maintain LIBOR Loans. Upon receipt of such notice, Borrowers shall either repay the outstanding LIBOR Loans owed to the Banks, without penalty, on the last day of the current Interest Periods (or, if any Bank may not lawfully continue to maintain and fund such LIBOR Loans, immediately), or Borrowers may convert such LIBOR Loans at such appropriate time to Prime Rate Loans. 5.3 Increased Cost or Reduced Return. 5.3.1 If, after the date hereof, the adoption of any applicable law, rule, or regulation, or any change in any applicable law, rule, or regulation, or any change in the interpretation or administration thereof by any governmental authority, central bank, or comparable agency charged with the interpretation or administration thereof, or compliance by any Bank with any request or directive (whether or not having the force of law) of any such governmental authority, central bank, or comparable agency: (A) shall subject such Bank to any tax, duty, or other charge with respect to any LIBOR Loans, its Notes, or its obligation to make LIBOR Loans, or change the basis of taxation of any amounts payable to such Bank under this Agreement or its Notes in respect of any LIBOR Loans (other than franchise taxes and taxes imposed on the overall net income of such Bank); (B) shall impose, modify, or deem applicable any reserve, special deposit, assessment, or similar requirement (other than reserve requirements, if any, taken into account in the determination of the LIBOR Rate) relating to any extensions of credit or other assets of, or any deposits with or other liabilities or commitments of, such Bank, including the Commitment of such Bank hereunder; or (C) shall impose on such Bank or on the London interbank market any other condition affecting this Agreement or its Notes or any of such extensions of credit or liabilities or commitments; and the result of any of the foregoing is to increase the cost to such Bank of making, converting into, continuing, or maintaining any LIBOR Loans or to reduce any sum received or receivable by such Bank under this Agreement or its Notes with respect to any LIBOR Loans, then Borrowers shall pay to such Bank on demand such amount or amounts as will compensate such Bank for such increased cost or reduction. If any Bank requests compensation by Borrowers under this Section 5.3, Borrowers may, by notice to such Bank (with a copy to Agent), suspend the obligation of such Bank to make or continue LIBOR Loans, or to convert all or part of the Prime Rate Loan owing to such Bank to LIBOR Loans, until the event or condition giving rise to such request ceases to be in effect (in which case the provisions of Section 5.3 shall be applicable); provided that such suspension shall not affect the right of such Bank to receive the compensation so requested. 5.3.2 If, after the date hereof, any Bank shall have determined that the adoption of any applicable law, rule, or regulation regarding capital adequacy or any change therein or in the interpretation or administration thereof by any governmental authority, central bank, or comparable agency charged with the interpretation or administration thereof, or any request or directive regarding capital adequacy (whether or not having the force of law) of any such governmental authority, central bank, or comparable agency, has or would have the effect of reducing the rate of return on the capital of such Bank or any corporation controlling such Bank as a consequence of such Bank's obligations hereunder to a level below that which such Bank or such corporation could have achieved but for such adoption, change, request, or directive (taking into consideration its policies with respect to capital adequacy), then from time to time upon demand Borrowers shall pay to such Bank such additional amount or amounts as will compensate such Bank for such reduction. 5.3.3 Each Bank shall promptly notify Borrowers and Agent of any event of which it has knowledge, occurring after the date hereof, which will entitle such Bank to compensation pursuant to this Section 5.3 will designate a separate lending office, if applicable, if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the judgment of such Bank, be otherwise disadvantageous to it. Any Bank claiming compensation under this Section 5.3 shall furnish to Borrowers and Agent a statement setting forth the additional amount or amounts to be paid to it hereunder which shall be conclusive in the absence of manifest error. In determining such amount, such Bank may use any reasonable averaging and attribution methods. 5.3.4 Any Bank giving notice to the Borrowers through the Agent, pursuant to Section 5.3 shall give to the Borrowers a statement signed by an officer of such Bank setting forth in reasonable detail the basis for, and the calculation of such additional cost, reduced payments or capital requirements, as the case may be, and the additional amounts required to compensate such Bank therefor. 5.3.5 Within five (5) Business Days after receipt by the Borrowers of any notice referred to in Section 5.3, the Borrowers shall pay to the Agent for the account of the Bank issuing such notice such additional amounts as are required to compensate such Bank for the increased cost, reduce payments or increase capital requirements identified therein, as the case may be; provided, that the Borrowers shall not be obligated to compensate such Bank for any increased costs, reduced payments or increased capital requirements to the extent that such Bank incurs the same prior to a date six (6) months before such Bank gives the required notice. 5.4 Discretion of Bank as to Manner of Funding. Notwithstanding any provisions of this Agreement to the contrary, each Bank shall be entitled to fund and maintain its funding of all or any part of its Loans in any manner it sees fit, it being understood, however, that for the purposes of this Agreement all determinations hereunder shall be made as if each Bank had actually funded and maintained each LIBOR Loan through the purchase of deposits having a maturity corresponding to the last day of the LIBOR Interest Period applicable to such LIBOR Loan and bearing an interest rate to the applicable interest rate for such LIBOR Period. 5.5 Breakage Fees. Without duplication under any other provision hereof, if any Bank incurs any loss, cost or expense (including, without limitation, any loss of profit and loss, cost, expense or premium reasonably incurred by reason of the liquidation or re-employment of deposits or other funds acquired by such Bank to fund or maintain any LIBOR Loan or the relending or reinvesting of such deposits or amounts paid or prepaid to the Banks) as a result of any of the following events other than any such occurrence as a result in the change of circumstances described in Sections 5.1 and 5.2 above: 5.5.1 any payment, prepayment or conversion of a LIBOR Loan on a date other than the last day of its LIBOR Interest Period (whether by acceleration, prepayment or otherwise); 5.5.2 any failure to make a principal payment of a LIBOR Loan on the due date thereof; or 5.5.3 any failure by the Borrowers to borrow, continue, prepay or convert to a LIBOR Loan on the dates specified in a notice given pursuant to Section 2.3 or 4.3 hereof; then the Borrowers shall pay to such Bank such amount as will reimburse such Bank for such loss, cost or expense. If any Bank makes such a claim for compensation, it shall furnish to Borrowers and Agent a statement setting forth the amount of such loss, cost or expense in reasonable detail (including an explanation of the basis for and the computation of such loss, cost or expense) and the amounts shown on such statement shall be conclusive and binding absent manifest error. 6. Collateral Security. 6.1 Pledge of Collateral. To secure the performance by Borrowers of their obligations hereunder, and under the Notes and Security Instruments, whether now or hereafter incurred, matured or unmatured, direct or contingent, joint or several, or joint and several, including extensions, modifications, renewals and increases thereof, and substitutions therefore, Borrowers have heretofore granted and assigned to Bank One-Oklahoma and/or MidFirst Bank a first and prior lien on certain of their Oil and Gas Properties, certain related equipment, oil and gas inventory and the proceeds of the foregoing. Contemporaneously with the execution of this Agreement and the Notes, the Borrowers shall grant and assign to Agent for the ratable benefit of the Banks a first and prior Lien on certain of its Oil and Gas Properties, certain related equipment, oil and gas inventory, certain bank accounts, the System, the Plant and proceeds of the foregoing. The Oil and Gas Properties heretofore and herewith mortgaged to the Agent shall represent not less than 70% of the Borrowers' aggregate present worth in proved developed producing properties, as determined by Borrowers' most recent engineering report dated January 1, 2002. All Oil and Gas Properties and other collateral in which Borrowers have heretofore granted to Bank One-Oklahoma, or herewith grant or hereafter grant to Agent for the ratable benefit of the Banks a first and prior Lien (to the satisfaction of the Agent) in accordance with this Section 6, as such properties and interests are from time to time constituted, are hereinafter collectively called the "Collateral". 6.2 Documentation and Title Review. The granting and assigning of such security interests and Liens by Borrowers shall be pursuant to Security Instruments in form and substance reasonably satisfactory to the Agent. Concurrently with the delivery of each of the Security Instruments or within a reasonable time thereafter, Borrowers shall furnish to the Agent mortgage and title opinions and other title information satisfactory to Agent with respect to the title and Lien status of Borrowers' interests in not less than 80% of the Engineered Value of the Oil and Gas Properties covered by the Security Instruments as Agent shall have designated. "Engineered Value" for this purpose shall mean future net revenues discounted at the discount rate being used by the Agent as of the date of any such determination utilizing the pricing parameters used in the engineering report furnished to the Agent for the ratable benefit of the Banks, pursuant to Sections 7 and 12 hereof. Borrowers will cause to be executed and delivered to the Agent, in the future, additional Security Instruments if the Agent reasonably deems such are necessary to insure perfection or maintenance of Banks' security interests and Liens in the Collateral or any part thereof. 6.3 Letters in Lieu of Transfer Orders. The Borrowers shall provide the Agent for the benefit of the Banks, undated letters in lieu of transfer orders, in form and substance satisfactory to Agent, from the Borrowers to each purchaser of hydrocarbons and disburser proceeds of hydrocarbons from and attributable to the Oil and Gas Properties, together with additional letters with addresses left blank authorizing and directing the addressees to make future payments attributable to hydrocarbons from the Oil and Gas Properties directly to the Agent for the benefit of the Banks. The Banks agree that none of the letters in lieu of transfer orders provided by the Borrowers pursuant to this Section 6.3 will be sent to the address prior to the occurrence of an Event of Default, at which time the Agent may, at its option and in addition to the exercise of any of its other rights and remedies, send any and all of such letters to such addressees; provided, however, that upon the occurrence of an Event of Default other than those specified in Sections 14.6 and 14.7, the Agent shall not send any or all of such letters until the applicable period to cure, if any, such Default has lapsed without such Default being cured. Borrowers hereby designate the Agent as its agent and attorney-in-fact, to act in its name, place and stead for the purpose of completing and delivering any and all letters in lieu of transfer orders delivered by the Borrowers to the Agent for the benefit of the Banks pursuant to Sections 6.3 and 12.24 hereof, including, without limitation, completing any blanks contained in such letters and attaching exhibits thereto describing the relevant Collateral. Borrowers hereby ratify and confirm all that the Agent shall lawfully do or cause to be done by virtue of this power of attorney and the rights granted with respect to such power of attorney. This power of attorney is coupled with the interests of the Agent in the Collateral, shall commence and be in full force and effect as of the Effective Date and shall remain in full force and effect and shall be irrevocable until the obligations, if any, of the Agent hereunder have terminated and the full satisfaction of all obligations due hereunder or under the Notes. The powers conferred on Agent by this appointment may only be exercised by the Agent by execution by any Person who, at the time of exercise, is an officer of the Agent, and are solely to protect the interests of the Agent and the Banks under the Loan Documents and shall not impose any duty upon the Agent to exercise any such powers. The Agent shall be accountable only for amounts that it actually receives or has expressly directed that others receive as a result of the exercise of such powers and shall not be responsible to the Borrowers, or any other Person for any act or failure to act with respect to such powers, except for gross negligence or willful misconduct. 7. Borrowing Base. 7.1 Initial Borrowing Base. At the Effective Date, the Borrowing Base shall be $70,000,000.00. 7.2 Subsequent Determinations of Borrowing Base. Subsequent determinations of the Borrowing Base shall be made by the Banks at least semi-annually based on engineering reports effectively dated January 1 and July 1 of each year beginning January 1, 2002 or as otherwise required to accommodate Unscheduled Redeterminations. The Borrowers shall furnish to the Banks as soon as possible but in any event no later than April 1 of each year, beginning April 1, 2002, with an engineering report in form and substance satisfactory to the Agent prepared by an independent petroleum engineering firm acceptable to Agent covering the Oil and Gas Properties utilizing economic and pricing parameters used by Agent as established from time to time, together with such other information concerning the value of the Oil and Gas Properties as the Agent shall deem necessary to determine the value of the Oil and Gas Properties. By October 1 of each year, or within thirty (30) days after either (i) receipt of notice from Agent that the Banks require an Unscheduled Redetermination, or (ii) the Borrowers give notice to Agent of their desire to have an Unscheduled Redetermination performed, the Borrowers shall furnish to the Banks an engineering report in form and substance satisfactory to Agent prepared by Borrowers' in-house engineering staff valuing the Oil and Gas Properties utilizing economic and pricing parameters used by the Agent as established from time to time, together with such other information, reports and data concerning the value of the Oil and Gas Properties as Agent shall deem reasonably necessary to determine the value of such Oil and Gas Properties. Agent shall by notice to the Borrowers no later than May 1 and November 1 of each year, or within a reasonable time thereafter (herein called the "Determination Date"), notify the Borrowers of the designation by the Banks of the new Borrowing Base for the period beginning on such Determination Date and continuing until, but not including, the next Determination Date. If an Unscheduled Redetermination is made by the Banks, the Agent shall notify the Borrowers within a reasonable time after receipt of all requested information of the new Borrowing Base, and such new Borrowing Base shall continue until the next Determination Date. If the Borrowers do not furnish all such information, reports and data by any date specified in this Section 7.2, the Banks may nonetheless designate the Borrowing Base at any amount which the Banks in their discretion determine and may redesignate the Borrowing Base from time to time thereafter until the Banks receive all such information, reports and data, whereupon the Banks shall designate a new Borrowing Base as described above. Each Bank shall determine the amount of the Borrowing Base based upon the loan value which such Bank in its discretion (using such methodology, assumptions and discounts rates as such Bank customarily uses in assigning loan value to oil and gas properties, oil and gas gathering systems, gas processing and plant operations) assigns to such Oil and Gas Properties and other Collateral of the Borrowers at the time in question and based upon such other credit factors consistently applied (including, without limitation, the assets, liabilities, cash flow, business, properties, prospects, management and ownership of the Borrowers and their affiliates) as such Bank customarily considers in evaluating similar oil and gas credits, but such Bank in its discretion shall not be required to give any additional positive value to any Oil and Gas Property over the current economic and pricing parameters used by such Bank for such Determination Date which additional value is derived directly from a hedging, forward sale or swap agreement covering such Oil and Gas Property as of the date of such determination. All determinations or Unscheduled Redeterminations of the Borrowing Base require the approval of Majority Banks; provided, however, that notwithstanding anything to the contrary herein, the amount of the Borrowing Base may not be increased, without the approval of all Banks. If the Banks cannot otherwise agree on the Borrowing Base, each Bank shall submit in writing to the Agent its proposed Borrowing Base and the Borrowing Base shall be set on the basis of the weighted average of the Borrowing Bases proposed by the Banks. If at any time any of the Oil and Gas Properties are sold, the Borrowing Base then in effect may be reduced as a result of an Unscheduled Redetermination . It is expressly understood that the Banks have no obligation to designate the Borrowing Base at any particular amounts, except in the exercise of their discretion. Provided, however, that the Banks shall not have the obligation to designate a Borrowing Base in an amount in excess of the Commitment or its legal or internal lending limits. The Banks shall have the right to perform an Unscheduled Redetermination of the Borrowing Base. 8. Fees. 8.1 Unused Commitment Fee. The Borrowers shall pay to Agent for the ratable benefit of the Banks an unused commitment fee (the "Unused Commitment Fee") equivalent to the Unused Fee Rate times the unadvanced amount of the Revolving Commitment (calculated on a daily basis). The Unused Commitment Fee shall be payable in arrears on the last Business Day of each calendar quarter beginning March 31, 2002 with the final fee payment due on the Revolving Maturity Date for any period then ending for which the Unused Commitment Fee shall not have been theretofore paid. In the event the Revolving Commitment terminates on any date prior to the end of any such monthly period, the Borrowers shall pay to the Agent for the ratable benefit of the Banks, on the date of such termination, the total Unused Commitment Fee due for the period in which such termination occurs. 8.2 The Letter of Credit Fee. Borrowers shall pay to the Agent the Letter of Credit fees required above in Section 2.5. 8.3 Upfront Fee. Borrowers shall pay to the Agent for the ratable benefit of Lenders an upfront fee in the amount of $50,000.00. Lenders not increasing their Commitment shall not be entitled to share in the Upfront Fee. 8.4 Other Fees. The Borrowers shall pay to the Agent such other fees as are agreed upon by Agent and Borrowers. 9. Prepayments. 9.1 Voluntary Prepayments. Subject to the provisions of Section 5.5 hereof, the Borrowers may at any time and from time to time, without penalty or premium, prepay the Notes, in whole or in part. Each such prepayment shall be made on at least three (3) London Business Days' notice to Agent in the case of LIBOR Loan Tranches and without notice in the case of Prime Rate Loan Tranches and shall be in a minimum amount of $100,000.00 or any larger multiple thereof or the unpaid balance on the Notes, whichever is less, plus accrued interest thereon to the date of prepayment. 9.2 Mandatory Prepayment For Borrowing Base Deficiency. In the event the Total Outstandings ever exceed the Borrowing Base as determined by Banks pursuant to Section 7.2 hereof, the Borrowers shall, within thirty (30) days after notification from the Agent, either (A) by instruments reasonably satisfactory in form and substance to the Bank, provide the Agent with collateral with value and quality in amounts satisfactory to all of the Banks in their discretion in order to increase the Borrowing Base by an amount at least equal to such excess, or (B) prepay, without premium or penalty, the principal amount of the Term Notes or the Revolving Notes, in Banks' discretion, in an amount at least equal to such excess plus accrued interest thereon to the date of prepayment. If the Total Outstandings ever exceed the Commitment as a result of any required reduction in the Commitment, then in such event, Borrowers shall immediately prepay the principal amount of the Term Notes or the Revolving Notes, in Banks' discretion, in an amount at least equal to such excess plus accrued interest to the date of prepayment. 10.

Nothing contained in this Section 14 shall be construed to limit or amend in any way the Events of Default enumerated in the Note, or any other document executed in connection with the transaction contemplated herein. Upon the occurrence and during the continuance of any Event of Default, the Banks are hereby authorized at any time and from time to time, without notice to the Borrowers (any such notice being expressly waived by the Borrowers), to set-off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by any of the Banks to or for the credit or the account of the Borrowers against any and all of the indebtedness of the Borrowers under the Notes and the Loan Documents, including this Agreement, irrespective of whether or not the Banks shall have made any demand under the Loan Documents, including this Agreement or the Notes and although such indebtedness may be unmatured. Any amount set-off by any of the Banks shall be applied against the indebtedness owed the Banks by the Borrowers pursuant to this Agreement and the Notes. The Banks agree promptly to notify the Borrowers after any such setoff and application, provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of the Bank under this Section are in addition to other rights and remedies (including, without limitation, other rights of set-off) which the Banks may have. 15. The Agent and the Banks. 15.1 Appointment and Authorization. Each Bank hereby appoints Agent as its nominee and agent, in its name and on its behalf: (i) to act as nominee for and on behalf of such Bank in and under all Loan Documents; (ii) to arrange the means whereby the funds of Banks are to be made available to the Borrowers under the Loan Documents; (iii) to take such action as may be requested by any Bank under the Loan Documents (when such Bank is entitled to make such request under the Loan Documents); (iv) to receive all documents and items to be furnished to Banks under the Loan Documents; (v) to be the secured party, mortgagee, beneficiary, and similar party in respect of, and to receive, as the case may be, any collateral for the benefit of Banks; (vi) to promptly distribute to each Bank all material information, requests, documents and items received from the Borrowers under the Loan Documents; (vii) to promptly distribute to each Bank such Bank's Pro Rata Part of each payment or prepayment (whether voluntary, as proceeds of insurance thereon, or otherwise) in accordance with the terms of the Loan Documents and (viii) to deliver to the appropriate Persons requests, demands, approvals and consents received from Banks. Each Bank hereby authorizes Agent to take all actions and to exercise such powers under the Loan Documents as are specifically delegated to Agent by the terms hereof or thereof, together with all other powers reasonably incidental thereto. With respect to its commitments hereunder and the Notes issued to it, Agent and any successor Agent shall have the same rights under the Loan Documents as any other Bank and may exercise the same as though it were not the Agent; and the term "Bank" or "Banks" shall, unless otherwise expressly indicated, include Agent and any successor Agent in its capacity as a Bank. Agent and any successor Agent and its Affiliates may accept deposits from, lend money to, act as trustee under indentures of and generally engage in any kind of business with the Borrowers, and any person which may do business with the Borrowers, all as if Agent and any successor Agent was not Agent hereunder and without any duty to account therefor to the Banks; provided that, if any payments in respect of any property (or the proceeds thereof) now or hereafter in the possession or control of Agent which may be or become security for the obligations of the Borrowers arising under the Loan Documents by reason of the general description of indebtedness secured or of property contained in any other agreements, documents or instruments related to any such other business shall be applied to reduction of the obligations of the Borrowers arising under the Loan Documents, then each Bank shall be entitled to share in such application according to its pro rata part thereof. Each Bank, upon request of any other Bank, shall disclose to all other Banks all indebtedness and liabilities, direct and contingent, of the Borrowers to such Bank as of the time of such request. 15.2 Note Holders. From time to time as other Banks become a party to this Agreement, Agent shall obtain execution by the Borrowers of additional Notes in amounts representing the Commitment of each such new Bank, up to an aggregate face amount of all Revolving Notes not exceeding $45,700,000.00 and up to an aggregate face amount of all Term Notes not exceeding $24,300,000.00. The obligation of such Bank shall be governed by the provisions of this Agreement, including but not limited to, the obligations specified in Section 2 hereof. From time to time, Agent may require that the Banks exchange their Notes for newly issued Notes to better reflect the Commitments of the Banks. Agent may treat the payee of any Note as the holder thereof until written notice of transfer has been filed with it, signed by such payee and in form satisfactory to Agent. 15.3 Consultation with Counsel. Banks agree that Agent may consult with legal counsel selected by Agent and shall not be liable for any action taken or suffered in good faith by it in accordance with the advice of such counsel. 15.4 Documents. Agent shall not be under a duty to examine or pass upon the validity, effectiveness, enforceability, genuineness or value of any of the Loan Documents or any other instrument or document furnished pursuant thereto or in connection therewith, and Agent shall be entitled to assume that the same are valid, effective, enforceable and genuine and what they purport to be. 15.5 Resignation or Removal of Agent. Subject to the appointment and acceptance of a successor Agent as provided below, Agent may resign at any time by giving written notice thereof to Banks and the Borrowers, and Agent may be removed at any time with or without cause by all Banks. If no successor Agent has been so appointed by all Banks (and approved by the Borrowers) and has accepted such appointment within 30 days after the retiring Agent's giving of notice of resignation or removal of the retiring Agent, then the retiring Agent may, on behalf of Banks, appoint a successor Agent. Any successor Agent must be approved by Borrowers, which approval will not be unreasonably withheld. 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 and duties of the retiring Agent, and the retiring Agent, shall be discharged from its duties and obligations hereunder. After any retiring Agent's resignation or removal hereunder as Agent, the provisions of this Section 15 shall continue in effect for its benefit in respect to any actions taken or omitted to be taken by it while it was acting as Agent. To be eligible to be an Agent hereunder the party serving, or to serve, in such capacity must own a Pro Rata Part of the Commitments equal to the level of Commitment required to be held by any Bank pursuant to Section 28 hereof. 15.6 Responsibility of Agent. It is expressly understood and agreed that the obligations of Agent under the Loan Documents are only those expressly set forth in the Loan Documents as to each and that Agent, shall be entitled to assume that no Default or Event of Default has occurred and is continuing, unless Agent has actual knowledge of such fact or has received notice from a Bank or the Borrowers that such Bank or the Borrowers considers that a Default or an Event of Default has occurred and is continuing and specifying the nature thereof. Neither Agent nor any of its directors, officers, attorneys or employees shall be liable for any action taken or omitted to be taken by them under or in connection with the Loan Documents, except for its or their own gross negligence or willful misconduct. Agent shall not incur liability under or in respect of any of the Loan Documents by acting upon any notice, consent, certificate, warranty or other paper or instrument believed by it to be genuine or authentic or to be signed by the proper party or parties, or with respect to anything which it may do or refrain from doing in the reasonable exercise of its judgment, or which may seem to it to be necessary or desirable. Agent shall not be responsible to Banks for any of the Borrowers' recitals, statements, representations or warranties contained in any of the Loan Documents, or in any certificate or other document referred to or provided for in, or received by any Bank under, the Loan Documents, or for the value, validity, effectiveness, genuineness, enforceability or sufficiency of or any of the Loan Documents or for any failure by the Borrowers to perform any of its obligations hereunder or thereunder. Agent may employ agents and attorneys-in-fact and shall not be answerable, except as to money or securities received by it or its authorized agents, for the negligence or misconduct of any such agents or attorneys-in-fact selected by it with reasonable care. The relationship between Agent and each Bank is only that of agent and principal and has no fiduciary aspects. Nothing in the Loan Documents or elsewhere shall be construed to impose on Agent any duties or responsibilities other than those for which express provision is therein made. In performing its duties and functions hereunder, Agent does not assume and shall not be deemed to have assumed, and hereby expressly disclaims, any obligation or responsibility toward or any relationship of agency or trust with or for the Borrower or any of its beneficiaries or other creditors. As to any matters not expressly provided for by the Loan Documents, Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of all Banks and such instructions shall be binding upon all Banks and all holders of the Notes; provided, however, that Agent shall not be required to take any action which is contrary to the Loan Documents or applicable law. Agent shall have the right to exercise or refrain from exercising, without notice or liability to the Banks, any and all rights afforded to Agent by the Loan Documents or which Agent may have as a matter of law; provided, however, Agent shall not (i) except as provided in Section 7.2 hereof, without the consent of Majority Banks designate the amount of the Borrowing Base or (ii) without the consent of Majority Banks, take any other action with regard to amending the Loan Documents, waiving any default under the Loan Documents or taking any other action with respect to the Loan Documents which requires consent of all Banks. Provided further, however, that no amendment, waiver, or other action shall be effected pursuant to the preceding clause (ii) without the consent of the Banks which: (i) would increase the Borrowing Base, (ii) would reduce any fees hereunder, or the principal of, or the interest on, any Bank's Note or Notes, (iii) would postpone any date fixed for any payment of any fees hereunder, or any principal or interest of any Bank's Note or Notes, (iv) would materially increase any Bank's obligations hereunder or would materially alter Agent's obligations to any Bank hereunder, (v) would release Borrowers from their obligation to pay any Bank's Note or Notes or to honor the terms of any guaranty agreement executed in conjunction herewith, (vi) release any of the Collateral, (vii) would change the definition of all Banks, (viii) would amend, modify or change any provision of this Agreement requiring the consent of all the Banks, (ix) would waive any of the conditions precedent to the Effective Date or the making of any Loan or issuance of any Letter of Credit or (x) would extend the Revolving Maturity Date or (xi) would amend this sentence or the previous sentence. Agent shall not have liability to Banks for failure or delay in exercising any right or power possessed by Agent pursuant to the Loan Documents or otherwise unless such failure or delay is caused by the gross negligence of the Agent, in which case only the Agent responsible for such gross negligence shall have liability therefor to the Banks. 15.7 Independent Investigation. Each Bank severally represents and warrants to Agent that it has made its own independent investigation and assessment of the financial condition and affairs of the Borrowers in connection with the making and continuation of its participation hereunder and has not relied exclusively on any information provided to such Bank by Agent in connection herewith, and each Bank represents, warrants and undertakes to Agent that it shall continue to make its own independent appraisal of the credit worthiness of the Borrowers while the Notes are outstanding or its commitments hereunder are in force. Agent shall not be required to keep itself informed as to the performance or observance by the Borrowers of this Agreement or any other document referred to or provided for herein or to inspect the properties or books of the Borrowers. Other than as provided in this Agreement, Agent shall not have any duty, responsibility or liability to provide any Bank with any credit or other information concerning the affairs, financial condition or business of the Borrowers which may come into the possession of Agent. 15.8 Indemnification. Banks agree to indemnify Agent, ratably according to their respective Commitments on a Pro Rata basis, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any proper and reasonable kind or nature whatsoever which may be imposed on, incurred by or asserted against Agent in any way relating to or arising out of the Loan Documents or any action taken or omitted by Agent under the Loan Documents, provided that no Bank shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from Agent's gross negligence or willful misconduct. Each Bank shall be entitled to be reimbursed by the Agent for any amount such Bank paid to Agent under this Section 15.8 to the extent the Agent has been reimbursed for such payments by the Borrowers or any other Person. The parties intend for the provisions of this Section to apply to and protect the Agent from the consequences of any liability including strict liability imposed or threatened to be imposed on Agent as well as from the consequences of its own negligence, whether or not that negligence is the sole, contributing or concurring cause of any such liability. 15.9 Benefit of Section 15. The agreements contained in this Section 15 are solely for the benefit of Agent and the Banks and are not for the benefit of, or to be relied upon by, the Borrowers, any affiliate of the Borrowers or any other person. 15.10 Pro Rata Treatment. Subject to the provisions of this Agreement, each payment (including each prepayment) by the Borrowers and collection by Banks (including offsets) on account of the principal of and interest on the Notes and fees provided for in this Agreement, payable by the Borrowers shall be made Pro Rata; provided, however, in the event that any Defaulting Bank shall have failed to make an Advance as contemplated under Section 3 hereof and Agent or another Bank or Banks shall have made such Advance, payment received by Agent for the account of such Defaulting Bank or Banks shall not be distributed to such Defaulting Bank or Banks until such Advance or Advances shall have been repaid in full to the Bank or Banks who funded such Advance or Advances. 15.11 Assumption as to Payments. Except as specifically provided herein, unless Agent shall have received notice from the Borrowers prior to the date on which any payment is due to Banks hereunder that the Borrowers will not make such payment in full, Agent may, but shall not be required to, assume that the Borrowers have made such payment in full to Agent on such date and Agent may, in reliance upon such assumption, cause to be distributed to each Bank on such due date an amount equal to the amount then due such Bank. If and to the extent the Borrowers shall not have so made such payment in full to Agent, each Bank shall repay to Agent forthwith on demand such amount distributed to such Bank together with interest thereon, for each day from the date such amount is distributed to such Bank until the date such Bank repays such amount to Agent, at the interest rate applicable to such portion of the Revolving Loan. 15.12 Other Financings. Without limiting the rights to which any Bank otherwise is or may become entitled, such Bank shall have no interest, by virtue of this Agreement or the Loan Documents, in (a) any present or future loans from, letters of credit issued by, or leasing or other financial transactions by, any other Bank to, on behalf of, or with the Borrowers (collectively referred to herein as "Other Financings") other than the obligations hereunder; (b) any present or future guarantees by or for the account of the Borrowers which are not contemplated by the Loan Documents; (c) any present or future property taken as security for any such Other Financings; or (d) any property now or hereafter in the possession or control of any other Bank which may be or become security for the obligations of the Borrowers arising under any loan document by reason of the general description of indebtedness secured or property contained in any other agreements, documents or instruments relating to any such Other Financings. 15.13 Interests of Banks. Nothing in this Agreement shall be construed to create a partnership or joint venture between Banks for any purpose. Agent, Banks and the Borrowers recognize that the respective obligations of Banks under the Commitment shall be several and not joint and that neither Agent nor any of Banks shall be responsible or liable to perform any of the obligations of the other under this Agreement. Each Bank is deemed to be the owner of an undivided interest in and to all rights, titles, benefits and interests belonging and accruing to Agent under the Security Instruments, including, without limitation, liens and security interests in any collateral, fees and payments of principal and interest by the Borrowers under the Commitment on a Pro Rata basis. Each Bank shall perform all duties and obligations of Banks under this Agreement in the same proportion as its ownership interest in the Loans outstanding at the date of determination thereof. 15.14 Investments. Whenever Agent in good faith determines that it is uncertain about how to distribute to Banks any funds which it has received, or whenever Agent in good faith determines that there is any dispute among the Banks about how such funds should be distributed, Agent may choose to defer distribution of the funds which are the subject of such uncertainty or dispute. If Agent in good faith believes that the uncertainty or dispute will not be promptly resolved, or if Agent is otherwise required to invest funds pending distribution to the Banks, Agent may invest such funds pending distribution (at the risk of the Borrowers). All interest on any such investment shall be distributed upon the distribution of such investment and in the same proportions and to the same Persons as such investment. All monies received by Agent for distribution to the Banks (other than to the Person who is Agent in its separate capacity as a Bank) shall be held by the Agent pending such distribution solely as Agent for such Banks, and Agent shall have no equitable title to any portion thereof. 16. Exercise of Rights. No failure to exercise, and no delay in exercising, on the part of the Agent or the Banks, any right hereunder shall operate as a waiver thereof, nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right. The rights of the Agent and the Banks hereunder shall be in addition to all other rights provided by law. No modification or waiver of any provision of the Loan Documents, including this Agreement, or the Note nor consent to departure therefrom, shall be effective unless in writing, and no such consent or waiver shall extend beyond the particular case and purpose involved. No notice or demand given in any case shall constitute a waiver of the right to take other action in the same, similar or other circumstances without such notice or demand. 17. Notices. Any notices or other communications required or permitted to be given by this Agreement or any other documents and instruments referred to herein must be given in writing (which may be by facsimile transmission) and must be personally delivered or mailed by prepaid certified or registered mail to the party to whom such notice or communication is directed at the address of such party as follows: (a) BORROWERS: c/o CONTINENTAL RESOURCES, INC., P.O. Box 1032, Enid, Oklahoma 73702, Facsimile No.: 580/548-5281, Attention: Harold Hamm and Roger Clement; (b) AGENT: MIDFIRST BANK, MidFirst Plaza, P.O. Box 268879, Oklahoma City, Oklahoma 73126, Facsimile No.405/767-7120, Attention: Shawn Brewer, Assistant Vice President. Any such notice or other communication shall be deemed to have been given (whether actually received or not) on the day it is personally delivered or delivered by facsimile as aforesaid or, if mailed, on the third day after it is mailed as aforesaid. Any party may change its address for purposes of this Agreement by giving notice of such change to the other party pursuant to this Section 17. Any notice required to be given to the Banks shall be given to the Agent and distributed to all Banks by the Agent. 18. Expenses. The Borrowers shall pay (i) all reasonable and necessary out-of-pocket expenses of the Banks, including reasonable fees and disbursements of special counsel for the Agent, in connection with the preparation of this Agreement, any waiver or consent hereunder or any amendment hereof or any default or Event of Default or alleged default or Event of Default hereunder, (ii) all reasonable and necessary out-of-pocket expenses of the Agent, including reasonable fees and disbursements of special counsel for the Agent in connection with the preparation of any participation agreement for a participant or participants requested by the Borrowers or any amendment thereof and (iii) if a default or an Event of Default occurs, all reasonable and necessary out-of-pocket expenses incurred by the Banks, including reasonable fees and disbursements of counsel, in connection with such default and Event of Default and collection and other enforcement proceedings resulting therefrom. The Borrowers shall indemnify the Banks against any transfer taxes, document taxes, assessments or charges made by any governmental authority by reason of the execution, delivery and filing of the Loan Documents. The obligations of this Section 18 shall survive any termination of this Agreement, the expiration of the Loans and the payment of all indebtedness of the Borrowers to the Banks hereunder and under the Notes. 19. Indemnity. The Borrowers agree to indemnify and hold harmless the Banks and their respective officers, employees, agents, attorneys and representatives (singularly, an "Indemnified Party", and collectively, the "Indemnified Parties") from and against any loss, cost, liability, damage or expense (including the reasonable fees and out-of-pocket expenses of counsel to the Banks, including all local counsel hired by such counsel) ("Claim") incurred by the Banks in investigating or preparing for, defending against, or providing evidence, producing documents or taking any other action in respect of any commenced or threatened litigation, administrative proceeding or investigation under any federal securities law, federal or state environmental law, or any other statute of any jurisdiction, or any regulation, or at common law or otherwise, which is alleged to arise out of or is based upon any acts, practices or omissions or alleged acts, practices or omissions of the Borrowers or their agents or arises in connection with the duties, obligations or performance of the Indemnified Parties in negotiating, preparing, executing, accepting, keeping, completing, countersigning, issuing, selling, delivering, releasing, assigning, handling, certifying, processing or receiving or taking any other action with respect to the Loan Documents and all documents, items and materials contemplated thereby even if any of the foregoing arises out of an Indemnified Party's ordinary negligence. The indemnity set forth herein shall be in addition to any other obligations or liabilities of the Borrowers to the Banks hereunder or at common law or otherwise, and shall survive any termination of this Agreement, the expiration of the Loans and the payment of all indebtedness of the Borrowers to the Banks hereunder and under the Notes, provided that the Borrowers shall have no obligation under this Section to the Bank with respect to any of the foregoing arising out of the gross negligence or willful misconduct of the Bank. If any Claim is asserted against any Indemnified Party, the Indemnified Party shall endeavor to notify the Borrowers of such Claim (but failure to do so shall not affect the indemnification herein made except to the extent of the actual harm caused by such failure). The Indemnified Party shall have the right to employ, at the Borrowers' expense, counsel of the Indemnified Parties' choosing and to control the defense of the Claim. The Borrowers may at their own expense also participate in the defense of any Claim. Each Indemnified Party may employ separate counsel in connection with any Claim to the extent such Indemnified Party believes it reasonably prudent to protect such Indemnified Party. The parties intend for the provisions of this Section to apply to and protect each Indemnified Party from the consequences of any liability including strict liability imposed or threatened to be imposed on Agent as well as from the consequences of its own negligence, whether or not that negligence is the sole, contributing, or concurring cause of any Claim. 20. Governing Law. THIS AGREEMENT IS BEING EXECUTED AND DELIVERED, AND IS INTENDED TO BE PERFORMED, IN OKLAHOMA COUNTY, OKLAHOMA, AND THE SUBSTANTIVE LAWS OF OKLAHOMA SHALL GOVERN THE VALIDITY, CONSTRUCTION, ENFORCEMENT AND INTERPRETATION OF THIS AGREEMENT AND ALL OTHER DOCUMENTS AND INSTRUMENTS REFERRED TO HEREIN, UNLESS OTHERWISE SPECIFIED THEREIN. 21. Invalid Provisions. If any provision of this Agreement is held to be illegal, invalid, or unenforceable under present or future laws effective during the term of this Agreement, such provisions shall be fully severable and this Agreement shall be construed and enforced as if such illegal, invalid or unenforceable provision had never comprised a part of this Agreement, and the remaining provisions of the Agreement shall remain in full force and effect and shall not be affected by the illegal, invalid or unenforceable provision or by its severance from this Agreement. 22. Maximum Interest Rate. It is the intention of the parties hereto to comply strictly with any applicable usury laws as in effect from time to time and, in this regard, there shall never be taken, received, contracted for, collected, charged or received on any sums advanced hereunder interest in excess of that which would accrue at the Maximum Rate. If, under any circumstances, the aggregate amounts paid on the Notes or under this Agreement or any other Loan Document include amounts which by law are deemed interest and which would exceed the amount permitted if the Maximum Rate were in effect, the Borrowers stipulate that such payment and collection will have been and will be deemed to have been, to the fullest extent permitted by applicable laws of the State of Oklahoma or the United States of America, the result of mathematical error on the part of the Borrowers and the Agent; and the Agent shall promptly credit the amount of such excess to the principal amount due on the Notes, or if the principal amount due on the Notes shall have been paid in full, refund the amount of such excess to the Borrowers (to the extent only of such interest payments in excess of that which would have accrued and been payable on the basis of the Maximum Rate) upon discovery of such error by the Agent or notice thereof from the Borrowers. If the maturity of the Notes is accelerated by reason of an election of the Agent resulting from any Event of Default or otherwise in accordance with this Agreement, or in the event any prepayment, then such consideration that constitutes interest under applicable laws may never include amounts which are more than the Maximum Rate, and the amount of such excess, if any, provided for in this Agreement or otherwise shall be canceled automatically by the Agent as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited by the Agent on the principal amount due on the Notes, or if the principal amount due on the Notes shall have been paid in full, refunded by the Agent to the Borrowers. All sums paid, or agreed to be paid, to the Agent for the use, forbearance and detention of the proceeds of any Advance hereunder shall, to the extent permitted by applicable law, be amortized, prorated, allocated and spread throughout the full term hereof until paid in full so that the actual rate of interest is uniform but does not exceed the Maximum Rate throughout the full term hereof. 23. Amendments. This Agreement may be amended only by an instrument in writing executed by an authorized officer of the party against whom such amendment is sought to be enforced. 24. Multiple Counterparts. This Agreement may be executed in a number of identical separate counterparts, each of which for all purposes is to be deemed an original, but all of which shall constitute, collectively, one agreement. No party to this Agreement shall be bound hereby until a counterpart of this Agreement has been executed by all parties hereto. 25. Conflict. In the event any term or provision hereof is inconsistent with or conflicts with any provision of the Loan Documents, the terms or provisions contained in this Agreement shall be controlling. 26. Survival. All covenants, agreements, undertakings, representations and warranties made in the Loan Documents, including this Agreement, the Notes or other documents and instruments referred to herein shall survive all closings hereunder and shall not be affected by any investigation made by any party. 27. Parties Bound. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors, assigns, heirs, legal representatives and estates, provided, however, that the Borrowers may not, without the prior written consent of all of the Banks, assign any rights, powers, duties or obligations hereunder. 28. Assignments and Participations. 28.1 Each Bank shall have the right to sell, assign or transfer all or any part of its Note or Notes, its Commitments and its rights and obligations hereunder to one or more Affiliates, Banks, financial institutions, pension plans, insurance companies, investment funds, or similar Persons who are Eligible Assignees or to a Federal Reserve Bank; provided, that in connection with each sale, assignment or transfer (other than to an Affiliate, a Bank or a Federal Reserve Bank), the applicable Bank will consider the opinion and recommendation of Borrowers, which opinion and recommendation shall in no way be binding upon such Bank, and each such sale, assignment, or transfer (other than to an Affiliate, a Bank or a Federal Reserve Bank), shall require the consent of Agent, which consent will not be unreasonably withheld, and the assignee, transferee or recipient shall have, to the extent of such sale, assignment, or transfer, the same rights, benefits and obligations as it would if it were such Bank and a holder of such Note, Commitments and rights and obligations, including, without limitation, the right to vote on decisions requiring consent or approval of all Banks or Majority Banks and the obligation to fund its Commitments; provided, further, that (1) each such sale, assignment, or transfer (other than to an Affiliate, a Bank or a Federal Reserve Bank) shall be in an aggregate principal amount not less than $2,500,000.00, (2) each remaining Bank shall at all times maintain Commitments then outstanding in an aggregate principal amount at least equal to $2,500,000.00; (3) each such sale, assignment or transfer shall be of a Pro Rata portion of such Bank's Commitment , (4) no Bank may offer to sell its Note or Notes, Commitments, rights and obligations or interests therein in violation of any securities laws; and (5) no such assignments (other than to a Federal Reserve Bank) shall become effective until the assigning Bank and its assignee delivers to Agent and Borrowers an Assignment and Acceptance and the Note or Notes subject to such assignment and other documents evidencing any such assignment. An assignment fee in the amount of $5,000 for each such assignment (other than to an Affiliate, a Bank or the Federal Reserve Bank) will be payable to Agent by assignor or assignee. Within five (5) Business Days after its receipt of copies of the Assignment and Acceptance and the other documents relating thereto and the Note or Notes, the Borrowers shall execute and deliver to Agent (for delivery to the relevant assignee) a new Note or Notes evidencing such assignee's assigned Commitments and if the assignor Bank has retained a portion of its Commitments, a replacement Note in the principal amount of the Commitments retained by the assignor (except as provided in the last sentence of this Section 28.1 such Note or Notes to be in exchange for, but not in payment of, the Note or Notes held by such Bank). On and after the effective date of an assignment hereunder, the assignee shall for all purposes be a Bank, party to this Agreement and any other Loan Document executed by the Banks and shall have all the rights and obligations of a Bank under the Loan Documents, to the same extent as if it were an original party thereto, and no further consent or action by Borrowers, Banks or the Agent shall be required to release the transferor Bank with respect to its Commitments assigned to such assignee and the transferor Bank shall henceforth be so released. 28.2 Each Bank shall have the right to grant participations in all or any part of such Bank's Notes and Commitments hereunder to one or more pension plans, investment funds, insurance companies, financial institutions or other Persons, provided, that: (i) each Bank granting a participation shall retain the right to vote hereunder, and no participant shall be entitled to vote hereunder on decisions requiring consent or approval of Bank or Majority Banks (except as set forth in (iii) below); (ii) in the event any Bank grants a participation hereunder, such Bank's obligations under the Loan Documents shall remain unchanged, such Bank shall remain solely responsible to the other parties hereto for the performance of such obligations, such Bank shall remain the holder of any such Note or Notes for all purposes under the Loan Documents, and Agent, each Bank and Borrowers shall be entitled to deal with the Bank granting a participation in the same manner as if no participation had been granted; and (iii) no participant shall ever have any right by reason of its participation to exercise any of the rights of Banks hereunder, except that any Bank may agree with any participant that such Bank will not, without the consent of such participant (which consent may not be unreasonably withheld) consent to any amendment or waiver requiring approval of all Banks. 28.3 It is understood and agreed that any Bank may provide to assignees and participants and prospective assignees and participants financial information and reports and data concerning Borrowers' properties and operations which was provided to such Bank pursuant to this Agreement. 28.4 Upon the reasonable request of either Agent or Borrowers, each Bank will identify those to whom it has assigned or participated any part of its Notes and Commitment, and provide the amounts so assigned or participated. 29. Choice of Forum: Consent to Service of Process and Jurisdiction. THE OBLIGATIONS OF BORROWERS UNDER THE LOAN DOCUMENTS ARE PERFORMABLE IN OKLAHOMA COUNTY, OKLAHOMA. ANY SUIT, ACTION OR PROCEEDING AGAINST THE BORROWERS WITH RESPECT TO THE LOAN DOCUMENTS OR ANY JUDGMENT ENTERED BY ANY COURT IN RESPECT THEREOF, MAY BE BROUGHT IN THE COURTS OF THE STATE OF OKLAHOMA, COUNTY OF OKLAHOMA, OR IN THE UNITED STATES COURTS LOCATED IN OKLAHOMA COUNTY, OKLAHOMA AND THE BORROWERS HEREBY SUBMIT TO THE NON-EXCLUSIVE JURISDICTION OF SUCH COURTS FOR THE PURPOSE OF ANY SUCH SUIT, ACTION OR PROCEEDING.
