Commitments to Lend; Notes. Subject to the terms and conditions hereof, each Lender agrees to make loans to Borrower (herein called such Lender's "Loans") upon Borrower's request from time to time during the Commitment Period, provided that (a) subject to Sections 3.3, 3.4 and 3.6, all Lenders are requested to make Loans of the same Type in accordance with their respective Percentage Shares and as part of the same Borrowing, and (b) after giving effect to such Loans, the Facility Usage does not exceed the Borrowing Base determined as of the date on which the requested Loans are to be made or the Commitment. The aggregate amount of all Loans in any Borrowing of ABR Loans must be greater than or equal to $500,000 (any higher multiple of $100,000) or must equal the remaining availability under the Borrowing Base. The aggregate amount of all Loans in any Borrowing of Eurodollar Loans must be greater than or equal to $500,000 (any higher multiple of $100,000) or must equal the remaining availability under the Borrowing Base. Borrower may have no more than three Borrowings of Eurodollar Loans outstanding at any time. The obligation of Borrower to repay to each Lender the aggregate amount of all Loans made by such Lender, together with interest accruing in connection therewith, shall be evidenced by a single promissory note (herein called such Lender's "Note") made by Borrower payable to the order of such Lender in the form of Exhibit A with appropriate insertions. The amount of principal owing on any Lender's Note at any given time shall be the aggregate amount of all Loans theretofore made by such Lender minus all payments of principal theretofore received by such Lender on such Note. Interest on each Note shall accrue and be due and payable as provided herein and therein, with Eurodollar Loans bearing interest at the Eurodollar Rate and ABR Loans bearing interest at the Alternate Base Rate (subject to the applicability of the Default Rate and limited by the provisions of Section 10.9). Subject to the terms and conditions hereof, Borrower may borrow, repay, and reborrow hereunder. Section 2.2. Requests for New Loans. Borrower must give to Agent written notice (or telephonic notice promptly confirmed in writing) of any requested Borrowing of new Loans to be advanced by Lenders. Each such notice constitutes a "Borrowing Notice" hereunder and must: (a) specify (i) the aggregate amount of any such Borrowing of new ABR Loans and the date on which such ABR Loans are to be advanced, or (ii) the aggregate amount of any such Borrowing of new Eurodollar Loans, the date on which such Eurodollar Loans are to be advanced (which shall be the first day of the Interest Period which is to apply thereto), and the length of the applicable Interest Period; and (b) be received by Agent not later than 12:00 noon, New York City time, on (i) the day on which any such ABR Loans are to be made, or (ii) the third Business Day preceding the day on which any such Eurodollar Loans are to be made. Each such written request or confirmation must be made in the form and substance of the "Borrowing Notice" attached hereto as Exhibit B, duly completed. Each such telephonic request shall be deemed a representation, warranty, acknowledgment and agreement by Borrower as to the matters which are required to be set out in such written confirmation. Upon receipt of any such Borrowing Notice, Agent shall give each Lender prompt notice of the terms thereof. If all conditions precedent to such new Loans have been met, each Lender will on the date requested 18 promptly remit to Agent at Agent's office in Houston, Texas, the amount of such Lender's new Loan in immediately available funds, and upon receipt of such funds, unless to its actual knowledge any conditions precedent to such Loans have been neither met nor waived as provided herein, Agent shall promptly make such Loans available to Borrower. Unless Agent shall have received prompt notice from a Lender that such Lender will not make available to Agent such Lender's new Loan, Agent may in its discretion assume that such Lender has made such Loan available to Agent in accordance with this section and Agent may if it chooses, in reliance upon such assumption, make such Loan available to Borrower. If and to the extent such Lender shall not so make its new Loan available to Agent, such Lender and Borrower severally agree to pay or repay to Agent within three days after demand the amount of such Loan together with interest thereon, for each day from the date such amount was made available to Borrower until the date such amount is paid or repaid to Agent, with interest at (i) the Federal Funds Rate, if such Lender is making such payment and (ii) the interest rate applicable at the time to the other new Loans made on such date, if Borrower is making such repayment. If neither such Lender nor Borrower pay or repay to Agent such amount within such three-day period, Agent shall in addition to such amount be entitled to recover from such Lender and from Borrower, on demand, interest thereon at the Default Rate, calculated from the date such amount was made available to Borrower. The failure of any Lender to make any new Loan to be made by it hereunder shall not relieve any other Lender of its obligation hereunder, if any, to make its new Loan, but no Lender shall be responsible for the failure of any other Lender to make any new Loan to be made by such other Lender. Section 2.3. Continuations and Conversions of Existing Loans. Borrower may make the following elections with respect to Loans already outstanding: to convert ABR Loans to Eurodollar Loans, to convert Eurodollar Loans to ABR Loans on the last day of the Interest Period applicable thereto, or to continue Eurodollar Loans beyond the expiration of such Interest Period by designating a new Interest Period to take effect at the time of such expiration. In making such elections, Borrower may combine existing Loans made pursuant to separate Borrowings into one new Borrowing or divide existing Loans made pursuant to one Borrowing into separate new Borrowings. To make any such election, Borrower must give to Agent written notice (or telephonic notice promptly confirmed in writing) of any such conversion or continuation of existing Loans, with a separate notice given for each new Borrowing. Each such notice constitutes a "Continuation/Conversion Notice" hereunder and must: (a) specify the existing Loans which are to be continued or converted; (b) specify (i) the aggregate amount of any Borrowing of ABR Loans into which such existing Loans are to be continued or converted and the date on which such continuation or conversion is to occur, or (ii) the aggregate amount of any Borrowing of Eurodollar Loans into which such existing Loans are to be continued or converted, the date on which such continuation or conversion is to occur (which shall be the first day of the Interest Period which is to apply to such Eurodollar Loans), and the length of the applicable Interest Period; and (c) be received by Agent not later than 12:00 noon, New York City time, on (i) the day on which any such continuation or conversion to ABR Loans is to occur, or 19 (ii) the third Business Day preceding the day on which any such continuation or conversion to Eurodollar Loans is to occur. Each such written request or confirmation must be made in the form and substance of the "Continuation/Conversion Notice" attached hereto as Exhibit C, duly completed. Each such telephonic request shall be deemed a representation, warranty, acknowledgment and agreement by Borrower as to the matters which are required to be set out in such written confirmation. Upon receipt of any such Continuation/Conversion Notice, Agent shall give each Lender prompt notice of the terms thereof. Each Borrowing Notice shall be irrevocable and binding on Borrower. During the continuance of any Default, Borrower may not make any election to convert existing Loans into Eurodollar Loans or continue existing Loans as Eurodollar Loans. If (due to the existence of a Default or for any other reason) Borrower fails to timely and properly give any notice of continuation or conversion with respect to a Borrowing of existing Eurodollar Loans at least three days prior to the end of the Interest Period applicable thereto, such Eurodollar Loans shall automatically be converted into ABR Loans at the end of such Interest Period. No new funds shall be repaid by Borrower or advanced by any Lender in connection with any continuation or conversion of existing Loans pursuant to this section, and no such continuation or conversion shall be deemed to be a new advance of funds for any purpose; such continuations and conversions merely constitute a change in the interest rate applicable to already outstanding Loans. Section 2.4. Use of Proceeds. Borrower shall use all Loans to refinance indebtedness under the Existing Credit Agreement or the Acquisition Agreement, finance capital expenditures, and provide working capital for its operations and for other general business purposes. In no event shall the funds from any Loan be used directly or indirectly by any Person (i) for personal, family, household or agricultural purposes or (ii) for the purpose, whether immediate, incidental or ultimate, of purchasing, acquiring or carrying any "margin stock" or any "margin securities" (as such terms are defined respectively in Regulation U and Regulation G promulgated by the Board of Governors of the Federal Reserve System) or to extend credit to others directly or indirectly for the purpose of purchasing or carrying any such margin stock or margin securities or (iii) for the acquisition of any Person unless such acquisition has been approved by the board of directors, management committee or partners, as the case may be of such Person. Borrower represents and warrants that Borrower is not engaged principally, or as one of Borrower's important activities, in the business of extending credit to others for the purpose of purchasing or carrying such margin stock or margin securities. Section 2.5. Fees. (a) Commitment Fees. In consideration of each Lender's commitment to make Loans, Borrower will pay to Agent for the account of each Lender a commitment fee determined on a daily basis by applying the Commitment Fee Rate to such Lender's Percentage Share of the unused portion of the Borrowing Base on each day during the Commitment Period, determined for each such day by deducting from the amount of the Borrowing Base at the end of such day the Facility Usage. This commitment fee shall be due and payable in arrears on each ABR Payment Date and at the end of the Commitment Period. 20 (b) Other Fees. In addition to all other amounts due to Agent under the Loan Documents, Borrower will pay fees to Agent as described in a letter agreement of even date herewith between Agent and Borrower. Section 2.6. Optional Prepayments. Borrower may, upon one Business Day's notice in the case of ABR Loans, or three Business Days' notice in the case of Eurodollar Loans, to Agent for the account of each Lender, from time to time and without premium or penalty prepay the Notes, in whole or in part, so long as the aggregate amounts of all partial prepayments of principal on the Notes equals $500,000 or any higher integral multiple of $100,000, so long as Borrower pays all breakage costs associated with the prepayment of any Eurodollar Loan as provided in Section 3.5, and so long as Borrower does not make any prepayments which would reduce the unpaid principal balance of any Loan to less than $100,000 without first either (a) terminating this Agreement or (b) providing assurance satisfactory to Agent in its discretion that Lenders' legal rights under the Loan Documents are in no way affected by such reduction. Each prepayment of principal of a Eurodollar Loan under this section shall be accompanied by all interest then accrued and unpaid on the principal so prepaid. Any principal or interest prepaid pursuant to this section shall be in addition to, and not in lieu of, all payments otherwise required to be paid under the Loan Documents at the time of such prepayment. Section 2.7. Mandatory Prepayments. (a) If at any time the Facility Usage exceeds the Commitment (whether due to a reduction in the Commitment in accordance with this Agreement, or otherwise), Borrower shall immediately upon demand prepay the principal of the Loans in an amount at least equal to such excess. (b) If at any time the Facility Usage is less than the Commitment but in excess of the Borrowing Base (such excess being herein called a "Borrowing Base Deficiency"), Borrower shall, within five Business Days after Agent gives notice of such fact to Borrower, either: (i) prepay the principal of the Loans in an aggregate amount at least equal to such Borrowing Base Deficiency, or (ii) give notice to Agent electing to prepay the principal of the Loans in up to three monthly installments in an aggregate amount at least equal to such Borrowing Base Deficiency, with each such installment equal to or in excess of one-third of such Borrowing Base Deficiency, and with the first such installment to be paid one month after the giving of such notice and the subsequent installments to be due and payable at one month intervals thereafter until such Borrowing Base Deficiency has been eliminated, or (iii) give notice to Agent that Borrower desires to provide Agent with deeds of trust, mortgages, chattel mortgages, security agreements, financing statements and other security documents in form and substance satisfactory to Agent, granting, confirming, and perfecting first and prior liens or security interests in collateral acceptable to Required Lenders, to the extent needed to 21 allow Required Lenders to increase the Borrowing Base (as they in their reasonable discretion deem consistent with prudent oil and gas banking industry lending standards at the time) to an amount which eliminates such Borrowing Base Deficiency, and then provide such security documents within thirty days after Agent specifies such collateral to Borrower. If, prior to any such specification by Agent, Required Lenders determine that the giving of such security documents will not serve to eliminate such Borrowing Base Deficiency, then, within five Business Days after receiving notice of such determination, Borrower will elect to make, and thereafter make, the prepayments specified in either of the preceding subsections (i) or (ii) of this subsection (b). (c) Each prepayment of principal of a Eurodollar Loan under this section shall be accompanied by all interest then accrued and unpaid on the principal so prepaid. Any principal or interest prepaid pursuant to this section shall be in addition to, and not in lieu of, all payments otherwise required to be paid under the Loan Documents at the time of such prepayment. Section 2.8. Initial Borrowing Base. During the period from the date hereof to the first Determination Date the Borrowing Base shall be $80,000,000. Section 2.9. Subsequent Determinations of Borrowing Base. By each Evaluation Date (or in the case of an Evaluation Date pursuant to clause (a) of the definition of "Evaluation Date", within thirty days after such Evaluation Date), Borrower shall furnish to each Lender all information, reports and data which Agent has then requested concerning Restricted Persons' businesses and properties (including their oil and gas properties and interests and the reserves and production relating thereto), together with the Engineering Report described in Section 6.2 which is then due, if any; provided that in the case of any "Evaluation Date" pursuant to clause (a) of the definition thereof, Borrower shall deliver to Agent an Engineering Report of the type described in Section 6.2(e) by such Evaluation Date. Within thirty days after receiving such information, reports and data (or in the case of a determination of the Borrowing Base with respect to an Evaluation Date described in clause (d) of the definition of "Evaluation Date", within thirty days after such Evaluation Date), Required Lenders shall agree upon an amount for the Borrowing Base and Agent shall by notice to Borrower designate such amount as the new Borrowing Base available to Borrower hereunder, which designation shall take effect immediately on the date such notice is sent (herein called a "Determination Date") and shall remain in effect until but not including the next date as of which the Borrowing Base is redetermined. If Borrower does not furnish all such information, reports and data by the date specified in the first sentence of this section, Agent may nonetheless designate the Borrowing Base at any amount which Required Lenders determine and may redesignate the Borrowing Base from time to time thereafter until each Lender receives all such information, reports and data, whereupon Required Lenders shall designate a new Borrowing Base as described above. Required Lenders shall determine the amount of the Borrowing Base based upon the loan collateral value which they in their discretion assign to the various oil and gas properties included in the Collateral at the time in question and based upon such other credit factors (including without limitation the assets, liabilities, cash flow, hedged and unhedged exposure to price, foreign exchange rate, and interest rate changes, business, properties, 22 prospects, management and ownership of Borrower and its Affiliates) as they in their discretion deem significant. It is expressly understood that Lenders and Agent have no obligation to agree upon or designate the Borrowing Base at any particular amount, whether in relation to the Commitment or otherwise, and that Lenders' commitments to advance funds hereunder is determined by reference to the Borrowing Base from time to time in effect, which Borrowing Base shall be used to the extent permitted by Law and regulatory authorities, for the purposes of capital adequacy determination and reimbursements under Section 3.2. Should the last day for Lenders to redetermine the Borrowing Base in connection with a particular Evaluation Date be a day other than a Business Day, the period for such redetermination shall be extended to the next succeeding Business Day. Section 2.10. Maturity Date and Requests for Extension. The Loans shall be finally due and payable on the Maturity Date, subject to earlier maturity in accordance with the terms hereof; provided, that the Maturity Date may be extended at the written request of the Borrower for an additional one-year period upon the written approval of each Lender, which shall be determined in each Lender's sole discretion. Unless the Agent shall have received from the Borrower a written request regarding the extension of the Maturity Date at least sixty (60) days prior to the Maturity Date then in effect, the Lenders will not consider extending and will not extend the Maturity Date. If the Agent has received such a request for extension by such time, the Agent will notify the Borrower whether or not Lenders will extend the Maturity Date in writing at least thirty (30) days prior to the Maturity Date then in effect. ARTICLE III - Payments to Lenders Section 3.1. General Procedures. Borrower will make each payment which it owes under the Loan Documents to Agent for the account of the Lender Party to whom such payment is owed. Each such payment must be received by Agent not later than 12:00 noon, New York City time, on the date such payment becomes due and payable, in lawful money of the United States of America, without set-off, deduction or counterclaim, and in immediately available funds. Any payment received by Agent after such time will be deemed to have been made on the next following Business Day. Should any such payment become due and payable on a day other than a Business Day, the maturity of such payment shall be extended to the next succeeding Business Day, and, in the case of a payment of principal or past due interest, interest shall accrue and be payable thereon for the period of such extension as provided in the Loan Document under which such payment is due. Each payment under a Loan Document shall be due and payable at the place provided therein and, if no specific place of payment is provided, shall be due and payable at the place of payment of Agent's Note. When Agent collects or receives money on account of the Obligations, Agent shall distribute all money so collected or received, and each Lender Party shall apply all such money so distributed, as follows: (a) first, for the payment of all fees and expenses of Agent and its counsel which are then due; (b) then for the payment of all other Obligations which are then due (and if such money is insufficient to pay all such Obligations, first to any reimbursements due Agent under Section 6.9 or 10.4 and second to the partial payment of all other 23 Obligations then due in proportion to the amounts thereof, or as Lender Parties shall otherwise agree); (c) then for the prepayment of amounts owing under the Loan Documents (other than principal on the Notes) if so specified by Borrower; (d) then for the prepayment of principal on the Notes, together with accrued and unpaid interest on the principal so prepaid; and (e) last, for the payment or prepayment of any other Obligations. All payments applied to principal or interest on any Note shall be applied first to any interest then due and payable, then to principal then due and payable, and last to any prepayment of principal and interest in compliance with Sections 2.6 and 2.7. All distributions of amounts described in any of subsections (c), (d) or (e) above shall be made by Agent pro rata to each Lender Party then owed Obligations described in such subsection in proportion to all amounts owed to all Lender Parties which are described in such subsection. Section 3.2. Capital Reimbursement. If either (a) the introduction or implementation of or the compliance with or any change in or in the interpretation of any Law, or (b) the introduction or implementation of or the compliance with any 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 Lender Party (or any assignee of such Lender Party) or any corporation controlling any Lender Party (or its assignee), then, upon demand by such Lender Party, Borrower will pay to Agent for the benefit of such Lender Party, from time to time as specified by such Lender Party, such additional amount or amounts which such Lender Party shall reasonably determine to be appropriate to compensate such Lender Party or any corporation controlling such Lender Party in light of such circumstances, to the extent that such Lender Party reasonably determines that the amount of any such capital would be increased or the rate of return on any such capital would be reduced by or in whole or in part based on the existence of the face amount of such Lender Party's Loans or commitments under this Agreement. Section 3.3. Increased Cost of Eurodollar Loans. If any applicable Law (whether now in effect or hereinafter enacted or promulgated, including Regulation D) or any interpretation or administration thereof by any governmental authority charged with the interpretation or administration thereof (whether or not having the force of Law): (a) shall change the basis of taxation of payments to any Lender Party of any principal, interest, or other amounts attributable to any Eurodollar Loan or otherwise due under this Agreement in respect of any Eurodollar Loan (other than taxes imposed on the overall net income of such Lender Party or any lending office of such Lender Party by any jurisdiction in which such Lender Party or any such lending office is located); or (b) shall change, impose, modify, apply or deem applicable any reserve, special deposit or similar requirements in respect of any Eurodollar Loan (excluding those for which such Lender Party is fully compensated pursuant to adjustments made in 24 the definition of Eurodollar Rate) or against assets of, deposits with or for the account of, or credit extended by, such Lender Party; or (c) shall impose on any Lender Party or the interbank eurocurrency deposit market any other condition affecting any Eurodollar Loan, the result of which is to increase the cost to any Lender Party of funding or maintaining any Eurodollar Loan or to reduce the amount of any sum receivable by any Lender Party in respect of any Eurodollar Loan by an amount deemed by such Lender Party to be material, then such Lender Party shall promptly notify Agent and Borrower in writing of the happening of such event and of the amount required to compensate such Lender Party for such event (on an after-tax basis, taking into account any taxes on such compensation), whereupon (i) Borrower shall pay such amount to Agent for the account of such Lender Party and (ii) Borrower may elect, by giving to Agent and such Lender Party not less than three Business Days' notice, to convert all (but not less than all) of any such Eurodollar Loans into ABR Loans. Section 3.4. Availability. If (a) any change in applicable Laws, or in the interpretation or administration thereof of or in any jurisdiction whatsoever, domestic or foreign, shall make it unlawful or impracticable for any Lender Party to fund or maintain Eurodollar Loans, or shall materially restrict the authority of any Lender Party to purchase or take offshore deposits of dollars (i.e., "eurodollars"), or (b) any Lender Party determines that matching deposits appropriate to fund or maintain any Eurodollar Loan are not available to it, or (c) any Lender Party determines that the formula for calculating the Adjusted Eurodollar Rate does not fairly reflect the cost to such Lender Party of making or maintaining loans based on such rate, then, upon notice by such Lender Party to Borrower and Agent, Borrower's right to elect Eurodollar Loans from such Lender Party shall be suspended to the extent and for the duration of such illegality, impracticability or restriction and all Eurodollar Loans of such Lender Party which are then outstanding or are then the subject of any Borrowing Notice and which cannot lawfully or practicably be maintained or funded shall immediately become or remain, or shall be funded as, ABR Loans of such Lender Party. Borrower agrees to indemnify each Lender Party and hold it harmless against all costs, expenses, claims, penalties, liabilities and damages which may result from any such change in Law, interpretation or administration. Such indemnification shall be on an after-tax basis, taking into account any taxes imposed on the amounts paid as indemnity. Section 3.5. Funding, Losses. In addition to its other obligations hereunder, Borrower will indemnify each Lender Party against, and reimburse each Lender Party on demand for, any loss or expense incurred or sustained by such Lender Party (including any loss or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by a Lender Party to fund or maintain Eurodollar Loans), as a result of (a) any payment or prepayment (whether authorized or required hereunder or otherwise) of all or a portion of a Eurodollar Loan on a day other than the day on which the applicable Interest Period ends, (b) any payment or prepayment, whether required hereunder or otherwise, of a Loan made after the delivery, but before the effective date, of a Continuation/Conversion Notice, if such payment or prepayment prevents such Continuation/Conversion Notice from becoming fully effective, (c) the failure of any Loan to be made or of any Continuation/Conversion Notice to become effective due to any condition precedent not being satisfied or due to any other action or inaction of any Restricted Person, or (d) any conversion (whether authorized or required hereunder or 25 otherwise) of all or any portion of any Eurodollar Loan into an ABR Loan or into a different Eurodollar Loan on a day other than the day on which the applicable Interest Period ends. Such indemnification shall be on an after-tax basis, taking into account any taxes imposed on the amounts paid as indemnity. Section 3.6. Reimbursable Taxes. Borrower covenants and agrees that: (a) Borrower will indemnify each Lender Party against and reimburse each Lender Party for all present and future income, stamp and other taxes, levies, costs and charges whatsoever imposed, assessed, levied or collected on or in respect of this Agreement or any Eurodollar Loans (whether or not legally or correctly imposed, assessed, levied or collected), excluding, however, any taxes imposed on or measured by the overall net income of Agent or such Lender Party or any lending office of such Lender Party by any jurisdiction in which such Lender Party or any such lending office is located (all such non-excluded taxes, levies, costs and charges being collectively called "Reimbursable Taxes" in this section). Such indemnification shall be on an after-tax basis, taking into account any taxes imposed on the amounts paid as indemnity. (b) All payments on account of the principal of, and interest on, each Lender Party's Loans and Note, and all other amounts payable by Borrower to any Lender Party hereunder, shall be made in full without set-off or counterclaim and shall be made free and clear of and without deductions or withholdings of any nature by reason of any Reimbursable Taxes, all of which will be for the account of Borrower. In the event of Borrower being compelled by Law to make any such deduction or withholding from any payment to any Lender Party, Borrower shall pay on the due date of such payment, by way of additional interest, such additional amounts as are needed to cause the amount receivable by such Lender Party after such deduction or withholding to equal the amount which would have been receivable in the absence of such deduction or withholding. If Borrower should make any deduction or withholding as aforesaid, Borrower shall within 60 days thereafter forward to such Lender Party an official receipt or other official document evidencing payment of such deduction or withholding. (c) If Borrower is ever required to pay any Reimbursable Tax with respect to any Eurodollar Loan, Borrower may elect, by giving to Agent and such Lender Party not less than three Business Days' notice, to convert all (but not less than all) of any such Eurodollar Loan into an ABR Loan, but such election shall not diminish Borrower's obligation to pay all Reimbursable Taxes. (d) Notwithstanding the foregoing provisions of this section, Borrower shall be entitled, to the extent it is required to do so by Law, to deduct or withhold (and not to make any indemnification or reimbursement for) income or other similar taxes imposed by the United States of America (other than any portion thereof attributable to a change in federal income tax Laws effected after the date hereof) from interest, fees or other amounts payable hereunder for the account of any Lender Party, other than a Lender Party (i) who is a U.S. person for Federal income tax purposes or (ii) who has the Prescribed Forms on file with Agent (with copies provided to Borrower) for the applicable year to the extent deduction or withholding of such taxes is not required as a 26 result of the filing of such Prescribed Forms, provided that if Borrower shall so deduct or withhold any such taxes, it shall provide a statement to Agent and such Lender Party, setting forth the amount of such taxes so deducted or withheld, the applicable rate and any other information or documentation which such Lender Party may reasonably request for assisting such Lender Party to obtain any allowable credits or deductions for the taxes so deducted or withheld in the jurisdiction or jurisdictions in which such Lender Party is subject to tax. As used in this section, "Prescribed Forms" means such duly executed forms or statements, and in such number of copies, which may, from time to time, be prescribed by Law and which, pursuant to applicable provisions of (x) an income tax treaty between the United States and the country of residence of the Lender Party providing the forms or statements, (y) the Internal Revenue Code of 1986, as amended from time to time, or (z) any applicable rules or regulations thereunder, permit Borrower to make payments hereunder for the account of such Lender Party free of such deduction or withholding of income or similar taxes. Section 3.7. Change of Applicable Lending Office. Each Lender Party agrees that, upon the occurrence of any event giving rise to the operation of any of Sections 3.2, 3.3, 3.4, 3.5 or 3.6 with respect to such Lender Party, it will, if requested by Borrower, use reasonable efforts (subject to overall policy considerations of such Lender Party) to designate another Lending Office, provided that such designation is made on such terms that such Lender Party and its Lending Office suffer no economic, legal or regulatory disadvantage, with the object of avoiding the consequence of the event giving rise to the operation of any such section. Nothing in this section shall affect or postpone any of the obligations of Borrower or the rights of any Lender Party provided in any of Sections 3.2, 3.3, 3.4, 3.5 or 3.6. Section 3.8. Replacement of Lenders. If any Lender Party seeks reimbursement for increased costs under any of Sections 3.2, 3.3, 3.4, 3.5 or 3.6, then within ninety days thereafter -- provided no Event of Default then exists -- Borrower shall have the right (unless such Lender Party withdraws its request for additional compensation) to replace such Lender Party by requiring such Lender Party to assign its Loans, Notes, Acquisition Notes and its commitments hereunder and under the Acquisition Agreement to an Eligible Transferee reasonably acceptable to Agent and to Borrower, provided that: (i) all Obligations of Borrower owing to such Lender Party being replaced (including such increased costs, but excluding principal and accrued interest on the Notes being assigned) shall be paid in full to such Lender Party concurrently with such assignment, and (ii) the replacement Eligible Transferee shall purchase the Note being assigned by paying to such Lender Party a price equal to the principal amount thereof plus accrued and unpaid interest thereon. In connection with any such assignment Borrower, Agent, such Lender Party and the replacement Eligible Transferee shall otherwise comply with Section 10.6. Notwithstanding the foregoing rights of Borrower under this section, however, Borrower may not replace any Lender Party which seeks reimbursement for increased costs under any of Sections 3.2, 3.3, 3.4, 3.5 or 3.6, unless Borrower is at the same time replacing all Lender Parties which are then seeking such compensation. In connection with any such replacement of a Lender Party, Borrower shall pay all costs that would have been due to such Lender Party pursuant to Section 3.5 if such Lender Party's Loans had been prepaid at the time of such replacement. 27 Section 3.9. Participants. If a Lender has assigned a participation in its Loans or commitment hereunder to another Person in accordance with Section 10.6, any amount otherwise payable by Borrower to such Lender under Section 3.3 through 3.6 (in this section called "Increased Costs"), shall include that portion of the Increased Costs determined by such Lender to be allocable to the amount of any interest or participation transferred by such Lender in such Lender's Loan or commitments under this Agreement.

The relationship of Agent to the other Lender Parties is only that of one commercial lender acting as administrative agent for others, and nothing in the Loan Documents shall be construed to constitute Agent a trustee or other fiduciary for any holder of any of the Notes or of any participation therein nor to impose on Agent duties and obligations other than those expressly provided for in the Loan Documents. With respect to any matters not expressly provided for in the Loan Documents and any matters which the Loan Documents place within the discretion of Agent, Agent shall not be required to exercise any discretion or take any action, and it may request instructions from Lenders with respect to any such matter, in which case it shall be required to act or to refrain from acting (and shall be fully protected and free from liability to all Lenders in so acting or refraining from acting) upon the instructions of Required Lenders (including itself), provided, however, that Agent shall not be required to take any action which exposes it to a risk of personal liability that it considers unreasonable or which is contrary to the Loan Documents or to applicable Law.

Each Lender Party acknowledges that it has, independently and without reliance upon any other Lender Party, made its own analysis of Borrower and the transactions contemplated hereby and its own independent decision to enter into this Agreement and the other Loan Documents. Each Lender Party also acknowledges that it will, independently and without reliance upon any other Lender Party and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under the Loan Documents. Section 9.4. Indemnification. Each Lender agrees to indemnify Agent (to the extent not reimbursed by Borrower within ten (10) days after demand) from and against such Lender's Percentage Share of any and all liabilities, obligations, claims, losses, damages, penalties, fines, actions, judgments, suits, settlements, costs, expenses or disbursements (including reasonable fees of attorneys, accountants, experts and advisors) of any kind or nature whatsoever (in this section collectively called "liabilities and costs") which to any extent (in whole or in part) may be imposed on, incurred by, or asserted against Agent growing out of, resulting from or in any other way associated with any of the Collateral, the Loan Documents and the transactions and events (including the enforcement thereof) at any time associated therewith or contemplated therein (including any Environmental Claims or violation or noncompliance with any Environmental Laws by any Person or any liabilities or duties of any Person with respect to the presence or Release of Hazardous Materials found in or released into the environment). THE FOREGOING INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH LIABILITIES AND COSTS ARE IN ANY WAY OR TO ANY EXTENT OWED, IN WHOLE OR IN PART, UNDER ANY CLAIM OR THEORY OF STRICT LIABILITY, OR ARE CAUSED, IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR OMISSION OF ANY KIND BY AGENT, provided only that no Lender shall be obligated under this section to indemnify Agent for that portion, if any, of any liabilities and costs which is proximately caused by Agent's own 50 individual gross negligence or willful misconduct, as determined in a final judgment. Cumulative of the foregoing, each Lender agrees to reimburse Agent promptly upon demand for such Lender's Percentage Share of any costs and expenses to be paid to Agent by Borrower under Section 10.4(a) to the extent that Agent is not timely reimbursed for such expenses by Borrower as provided in such section. As used in this section the term "Agent" shall refer not only to the Person designated as such in Section 1.1 but also to each director, officer, agent, attorney, employee, representative and Affiliate of such Person. Section 9.5. Rights as Lender. In its capacity as a Lender, Agent shall have the same rights and obligations as any Lender and may exercise such rights as though it were not Agent. Agent may accept deposits from, lend money to, act as Trustee under indentures of, and generally engage in any kind of business with any Restricted Person or their Affiliates, all as if it were not Agent hereunder and without any duty to account therefor to any other Lender. Section 9.6. Sharing of Set-Offs and Other Payments. Each Lender Party agrees that if it shall, whether through the exercise of rights under Security Documents or rights of banker's lien, set off, or counterclaim against Borrower or otherwise, obtain payment of a portion of the aggregate Obligations owed to it which, taking into account all distributions made by Agent under Section 3.1, causes such Lender Party to have received more than it would have received had such payment been received by Agent and distributed pursuant to Section 3.1, then (a) it shall be deemed to have simultaneously purchased and shall be obligated to purchase interests in the Obligations as necessary to cause all Lender Parties to share all payments as provided for in Section 3.1, and (b) such other adjustments shall be made from time to time as shall be equitable to ensure that Agent and all Lenders share all payments of Obligations as provided in Section 3.1; provided, however, that nothing herein contained shall in any way affect the right of any Lender Party to obtain payment (whether by exercise of rights of banker's lien, set-off or counterclaim or otherwise) of indebtedness other than the Obligations. Borrower expressly consents to the foregoing arrangements and agrees that any holder of any such interest or other participation in the Obligations, whether or not acquired pursuant to the foregoing arrangements, may to the fullest extent permitted by Law exercise any and all rights of banker's lien, set-off, or counterclaim as fully as if such holder were a holder of the Obligations in the amount of such interest or other participation. If all or any part of any funds transferred pursuant to this section is thereafter recovered from the seller under this section which received the same, the purchase provided for in this section shall be deemed to have been rescinded to the extent of such recovery, together with interest, if any, if interest is required pursuant to Tribunal order to be paid on account of the possession of such funds prior to such recovery. Section 9.7. Investments. Whenever Agent in good faith determines that it is uncertain about how to distribute to Lenders any funds which it has received, or whenever Agent in good faith determines that there is any dispute among Lenders 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 Lenders, Agent shall invest such funds pending distribution; all interest on any such investment shall be distributed upon the distribution of such investment and in the same proportion and to the same Persons as such investment. All moneys received by Agent for distribution to Lenders (other than to the Person who is Agent in its separate capacity as a Lender) shall be held by 51 Agent pending such distribution solely as Agent for such Lenders, and Agent shall have no equitable title to any portion thereof. Section 9.8. Benefit of Article IX. The provisions of this Article (other than the following Section 9.9) are intended solely for the benefit of Lender Parties, and no Restricted Person shall be entitled to rely on any such provision or assert any such provision in a claim or defense against any Lender Party. Lender Parties may waive or amend such provisions as they desire without any notice to or consent of Borrower or any Restricted Person. Section 9.9. Resignation. Agent may resign at any time by giving written notice thereof to Lenders and Borrower; provided that if Agent so resigns hereunder, it shall also resign as agent under the Acquisition Agreement. Each such notice shall set forth the date of such resignation. Required Lenders shall have the right to appoint a successor Agent; provided that they shall appoint the same Person as successor agent under the Acquisition Agreement. A successor must be appointed for any retiring Agent, and such Agent's resignation shall become effective when such successor accepts such appointment. If, within thirty days after the date of the retiring Agent's resignation, no successor Agent has been appointed and has accepted such appointment, then the retiring Agent may appoint a successor Agent, which shall be a financial institution organized under the Laws of the United States of America or of any state thereof. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, the retiring Agent shall be discharged from its duties and obligations under this Agreement and the other Loan Documents. After any retiring Agent's resignation hereunder the provisions of this Article IX shall continue to inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under the Loan Documents. Section 9.10. Lenders to Remain Pro Rata. It is the intent of all parties hereto that the pro rata share of each Lender in the Obligations and in the Acquisition Agreement Obligations shall be substantially the same at all times during the term of this Agreement. Accordingly, the initial Percentage Share of each Lender in the Commitment will be the same as the initial Percentage Share of such Lender in the Acquisition Commitment. All subsequent assignments and adjustments of the interests of the Lenders in the Obligations and the Acquisition Agreement Obligations will be made so as to maintain such a pro rata arrangement; provided that for the purposes of determining these pro rata shares, any Percentage Share held by any Lender's Affiliates shall be included in determining the interests of such Lender. ARTICLE X - Miscellaneous Section 10.1. Waivers and Amendments; Acknowledgments. (a) Waivers and Amendments. No failure or delay (whether by course of conduct or otherwise) by any Lender Party in exercising any right, power or remedy which such Lender Party may have under any of the Loan Documents shall operate as a waiver thereof or of any other right, power or remedy, nor shall any single or partial exercise by any Lender Party of any such right, power or remedy preclude any other or further exercise thereof or of any other right, power or remedy.

All grants, covenants and agreements contained in the Loan Documents shall bind and inure to the benefit of the parties thereto and their respective successors and assigns; provided, however, that no Restricted Person may assign or transfer any of its rights or delegate any of its duties or obligations under any Loan Document without the prior consent of Required Lenders. Neither Borrower nor any Affiliates of Borrower shall directly or indirectly purchase or otherwise retire any Obligations owed to any Lender nor will any Lender accept any offer to do so, unless each Lender shall have received substantially the same offer with respect to the same Percentage Share of the Obligations owed to it. If Borrower or any Affiliate of Borrower at any time purchases some but less than all of the Obligations owed to all Lender Parties, such purchaser shall not be entitled to any rights of any Lender Party under the Loan Documents unless and until Borrower or its Affiliates have purchased all of the Obligations. Section 10.6. Assignments. (a) Any Lender may sell a participation interest in its commitment hereunder or any of its rights under its Loans or under the Loan Documents to any Person, provided 56 that the agreement between such Lender and such participant must at all times provide: (i) that such participation exists only as a result of the agreement between such participant and such Lender and that such transfer does not give such participant any right to vote as a Lender or any other direct claims or rights against any Person other than such Lender, (ii) that such participant is not entitled to payment from any Restricted Person under any of Sections 3.2, 3.3, 3.4, 3.5 or 3.6 of amounts in excess of those payable to such Lender under such sections (determined without regard to the sale of such participation), and (iii) unless such participant is an Affiliate of such Lender, that such participant shall not be entitled to require such Lender to take any action under any Loan Document or to obtain the consent of such participant prior to taking any action under any Loan Document, except for actions which would require the consent of all Lenders under the next-to-last sentence of subsection (a) of Section 10.1. No Lender selling such a participation shall, as between the other parties hereto and such Lender, be relieved of any of its obligations hereunder as a result of the sale of such participation. Each Lender which sells any such participation to any Person (other than an Affiliate of such Lender) shall give prompt notice thereof to Agent and Borrower. (b) Except for sales of participations under the immediately preceding subsection (a), no Lender shall make any assignment or transfer of any kind of its commitments or any of its rights under its Loans or under the Loan Documents, except for assignments to an Eligible Transferee, and then only if such assignment is made in accordance with the following requirements: (i) Each such assignment shall apply to all Obligations owing to the assignor Lender hereunder and to the unused portion of the assignor Lender's commitments, so that after such assignment is made the assignor Lender shall have a fixed (and not a varying) Percentage Share in its Loans and Note and be committed to make that Percentage Share of all future Loans, the assignee shall have a fixed Percentage Share in such Loans and Note and be committed to make that Percentage Share of all future Loans, and the Percentage Share of the aggregate of the Commitment and the Acquisition Commitment of both the assignor and assignee shall equal or exceed $5,000,000. (ii) The parties to each such assignment shall execute and deliver to Agent, for its acceptance and recording in the "Register" (as defined below in this section), an Assignment and Acceptance in the form of Exhibit E, appropriately completed, together with the Note subject to such assignment and a processing fee payable to Agent of $4,000. Upon such execution, delivery, and payment and upon the satisfaction of the conditions set out in such Assignment and Acceptance, then (i) Borrower shall issue new Notes to such assignor and assignee upon return of the old Notes to Borrower, and (ii) as of the "Settlement Date" specified in such Assignment and Acceptance the assignee thereunder shall be a party hereto and a Lender hereunder and Agent shall thereupon deliver to Borrower and each Lender a schedule showing the revised Percentage Shares of such assignor Lender and such assignee Lender and the Percentage Shares of all other Lenders. 57 (iii) Each assignee Lender which is not a United States person (as such term is defined in Section 7701(a)(30) of the Internal Revenue Code of 1986, as amended) for Federal income tax purposes, shall (to the extent it has not already done so) provide Agent and Borrower with the "Prescribed Forms" referred to in Section 3.6(d). (iv) Together with each such assignment of its rights and obligations under this Agreement, such Lender shall assign the same Percentage Share of its rights and obligations under the Acquisition Agreement to the same Eligible Transferee or an Affiliate of such Eligible Transferee. (c) Nothing contained in this section shall prevent or prohibit any Lender from assigning or pledging all or any portion of its Loans and Note to any Federal Reserve Bank as collateral security pursuant to Regulation A of the Board of Governors of the Federal Reserve System and any Operating Circular issued by such Federal Reserve Bank or to one of its Affiliates; provided that no such assignment or pledge shall relieve such Lender from its obligations hereunder. (d) By executing and delivering an Assignment and Acceptance, each assignee Lender thereunder will be confirming to and agreeing with Borrower, Agents and each other Lender hereunder that such assignee understands and agrees to the terms hereof, including Article IX hereof. (e) Agent shall maintain a copy of each Assignment and Acceptance and a register for the recordation of the names and addresses of Lenders and the Percentage Shares of, and principal amount of the Loans owing to, each Lender from time to time (in this section called the "Register"). The entries in the Register shall be conclusive, in the absence of manifest error, and Borrower and each Lender Party may treat each Person whose name is recorded in the Register as a Lender hereunder for all purposes. The Register shall be available for inspection by Borrower or any Lender Party at any reasonable time and from time to time upon reasonable prior notice. Section 10.7. Confidentiality. Each Lender Party agrees that it will take all reasonable steps to keep confidential any proprietary information given to it by any Restricted Person, provided, however, that this restriction shall not apply to information which (i) has at the time in question entered the public domain, (ii) is required to be disclosed by Law (whether valid or invalid) of any Tribunal, (iii) is disclosed to any Lender Party's Affiliates, auditors, attorneys, or agents, (iv) is furnished to any other Lender Party or to any purchaser or prospective purchaser of participations or other interests in any Loan or Loan Document (provided each such purchaser or prospective purchaser first agrees to hold such information in confidence on the terms provided in this section), or (v) is disclosed in the course of enforcing its rights and remedies during the existence of an Event of Default. Section 10.8. Governing Law; Submission to Process. Except to the extent that the law of another jurisdiction is expressly elected in a Loan Document, the Loan Documents shall be deemed contracts and instruments made under the laws of the State of Texas and shall be construed and enforced in accordance with and governed by the laws of the State 58 of Texas and the laws of the United States of America, without regard to principles of conflicts of law. Chapter 346 of the Texas Finance Code (which regulates certain revolving credit loan accounts and revolving tri-party accounts) does not apply to this Agreement or to the Notes. Borrower hereby irrevocably submits itself and each other Restricted Person to the non-exclusive jurisdiction of the state and federal courts sitting in the State of Texas and agrees and consents that service of process may be made upon it or any Restricted Person in any legal proceeding relating to the Loan Documents or the Obligations by any means allowed under Texas or federal law. Section 10.9. Limitation on Interest. Lender Parties, Restricted Persons and any other parties to the Loan Documents intend to contract in strict compliance with applicable usury Law from time to time in effect. In furtherance thereof such Persons stipulate and agree that none of the terms and provisions contained in the Loan Documents shall ever be construed to create a contract to pay, for the use, forbearance or detention of money, interest in excess of the maximum amount of interest permitted to be charged by applicable Law from time to time in effect. Neither any Restricted Person nor any present or future guarantors, endorsers, or other Persons hereafter becoming liable for payment of any Obligation shall ever be liable for unearned interest thereon or shall ever be required to pay interest thereon in excess of the maximum amount that may be lawfully charged under applicable Law from time to time in effect, and the provisions of this section shall control over all other provisions of the Loan Documents which may be in conflict or apparent conflict herewith. Lender Parties expressly disavow any intention to charge or collect excessive unearned interest or finance charges in the event the maturity of any Obligation is accelerated. If (a) the maturity of any Obligation is accelerated for any reason, (b) any Obligation is prepaid and as a result any amounts held to constitute interest are determined to be in excess of the legal maximum, or (c) any Lender or any other holder of any or all of the Obligations shall otherwise collect moneys which are determined to constitute interest which would otherwise increase the interest on any or all of the Obligations to an amount in excess of that permitted to be charged by applicable Law then in effect, then all sums determined to constitute interest in excess of such legal limit shall, without penalty, be promptly applied to reduce the then outstanding principal of the related Obligations or, at such Lender's or holder's option, promptly returned to US Borrower or the other payor thereof upon such determination. In determining whether or not the interest paid or payable, under any specific circumstance, exceeds the maximum amount permitted under applicable Law, Lender Parties and Restricted Persons (and any other payors thereof) shall to the greatest extent permitted under applicable Law, characterize any non-principal payment as an expense, fee or premium rather than as interest, exclude voluntary prepayments and the effects thereof, and amortize, prorate, allocate, and spread the total amount of interest throughout the entire contemplated term of the instruments evidencing the Obligations in accordance with the amounts outstanding from time to time thereunder and the maximum legal rate of interest from time to time in effect under applicable Law in order to lawfully charge the maximum amount of interest permitted under applicable Law. In the event applicable Law provides for an interest ceiling under Chapter 303 of the Texas Finance Code (the "Texas Finance Code") as amended, for that day, the ceiling shall be the "weekly ceiling" as defined in the Texas Finance Code; provided that if any applicable Law permits greater interest, the Law permitting the greatest interest shall apply. As used in this section the term "applicable Law" means the Laws of the State of Texas or the Laws of the United States of America, whichever Laws allow the greater interest, as such Laws now exist or may be changed or amended or come into effect in the future. 59 Section 10.10. Termination: Limited Survival. In its sole and absolute discretion Borrower may at any time that no Obligations are owing elect in a written notice delivered to Agent to terminate this Agreement. Upon receipt by Agent of such a notice, if no Obligations are then owing this Agreement and all other Loan Documents shall thereupon be terminated and the parties thereto released from all prospective obligations thereunder. Notwithstanding the foregoing or anything herein to the contrary, any waivers or admissions made by any Restricted Person in any Loan Document, any Obligations under any of Sections 3.2, 3.3, 3.4, 3.5 or 3.6, and any obligations which any Person may have to indemnify or compensate any Lender Party shall survive any termination of this Agreement or any other Loan Document. At the request and expense of Borrower, Agent shall prepare and execute all necessary instruments to reflect and effect such termination of the Loan Documents. Agent is hereby authorized to execute all such instruments on behalf of all Lenders, without the joinder of or further action by any Lender. Section 10.11. Severability. If any term or provision of any Loan Document shall be determined to be illegal or unenforceable all other terms and provisions of the Loan Documents shall nevertheless remain effective and shall be enforced to the fullest extent permitted by applicable Law. Section 10.12. Counterparts. This Agreement may be separately executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to constitute one and the same Agreement. Section 10.13. Waiver of Jury Trial, Punitive Damages, etc. Borrower and each Lender Party hereby knowingly, voluntarily, intentionally, and irrevocably (a) waives, to the maximum extent not prohibited by Law, any right it may have to a trial by jury in respect of any litigation based hereon, or directly or indirectly at any time arising out of, under or in connection with the Loan Documents or any transaction contemplated thereby or associated therewith, before or after maturity; (b) waives, to the maximum extent not prohibited by Law, any right it may have to claim or recover in any such litigation any "Special Damages", as defined below, (c) certifies that no party hereto nor any representative or agent or counsel for any party hereto has represented, expressly or otherwise, or implied that such party would not, in the event of litigation, seek to enforce the foregoing waivers, and (d) acknowledges that it has been induced to enter into this Agreement, the other Loan Documents and the transactions contemplated hereby and thereby by, among other things, the mutual waivers and certifications contained in this section. As used in this section, "Special Damages" includes all special, consequential, exemplary, or punitive damages (regardless of how named), but does not include any payments or funds which any party hereto has expressly promised to pay or deliver to any other party hereto. Section 10.14. Release of Collateral. Agent and Lenders hereby agree that Agent shall release from the Security Documents, upon written request by Borrower and at Borrower's expense, interests in oil and gas properties sold by any Restricted Person in compliance with Section 7.5(c), upon receipt of the prepayment of the Loans required in connection with such sale, if any. No further authorization from Lenders shall be required in connection with any such release. 60 Section 10.15. Restatement. This Agreement restates and amends the Existing Revolving Credit Agreement in its entirety, and all of the terms and provisions hereof shall supersede the terms and conditions thereof. Borrower hereby agrees that (i) the Loans outstanding under the Existing Revolving Credit Agreement and all accrued and unpaid interest thereon, and (ii) all accrued and unpaid fees under the Existing Revolving Credit Agreement shall be deemed to be outstanding under and payable by this Agreement; provided that changes in the Percentage Shares, interest rates, or fee rates shall not change the amounts accrued and owing to each Lender under the Existing Revolving Credit Agreement. 61 IN WITNESS WHEREOF, this Agreement is executed as of the date first written above.
