Subject to the terms and conditions of this Agreement, Bank agrees to make one or more Advances to Borrower from time to time prior to the Commitment Termination Date, provided that the aggregate amount of all Advances at any time outstanding shall not exceed the lesser of (i) the Borrowing Base in effect from time to time; or (ii) the amount of the Commitment. Subject to the foregoing limitations and other terms of this Agreement, Borrower may borrow, repay and reborrow under the Commitment. The Obligation to repay the Advances made to Borrower pursuant to the Commitment shall be evidenced by Borrower's Note in the form of Exhibit 2.1 hereto, payable to the order of Bank. 16 Page 12 2.2 Borrowing Base. (a) On or before February 15 and August 15 of each year Borrower shall furnish to Bank (i) a report in form and substance satisfactory to Bank, of a petroleum engineer satisfactory to Bank, which report shall be dated as of January 1 and July 1 of such year and shall set forth the proven oil and gas reserves of Borrower, as of such date; (ii) any updated production history of the proven oil and gas reserves of Borrower; (iii) the discounted net present value (at a rate reasonably acceptable to Bank); (iv) the net general overhead and administrative expenses and the lease operating expenses attributable to the Oil and Gas Properties of Borrower for the prior twelve month period; and (v) such other information as to the operations of Borrower as Bank shall reasonably request. Together with each of the reports to be furnished pursuant to this Section 2.2(a) Borrower shall furnish to Bank such additional data and information concerning pricing, quantities or volume of production from or attributable to the Oil and Gas Properties with respect thereto as Bank may reasonably request. (b) After receipt of all of the information required by Section 2.2(a), Bank may redetermine the amount of the Borrowing Base in accordance with the customary practices of Bank for oil and gas loans to be effective as of April 1 and October 1 of such year. In connection with the initial Redetermination of the Borrowing Base as set forth herein, Borrower agrees to pay to Bank an Engineering Fee in the amount of $5,000.00. Thereafter, upon delivery to Bank of the information required by 2.2(a), Borrower shall pay to Bank an Engineering Fee in the amount of $5,000.00. Until the next determination of the amount of the Borrowing Base by Bank, the amount of the Borrowing Base as of the Closing Date shall be deemed to be $500,000 and thereafter, until each new determination of Borrowing Base is made by Bank, the amount of the Borrowing Base shall be deemed to be the Borrowing Base last deemed or calculated, as the case may be. In addition to the foregoing, Bank or Borrower may initiate a redetermination of the Borrowing Base at any other time as it so elects, provided, however, that Borrower may initiate only two (2) such unscheduled redeterminations during any consecutive twelve (12) month period by specifying in writing to Bank the date on which Borrower will furnish the information required by Section 2.2(a) and the date on which it desire such redetermination to occur. Bank shall have at least forty-five (45) days after the delivery of the information required by Section 2.2(a) to make any unscheduled redetermination of the Borrowing Base requested by Borrower. Bank may, at any time and at its expense, initiate an unscheduled redetermination of the Borrowing Base by specifying in writing to Borrower the date by which Borrower is to furnish the information required by Section 2.2(a) and the projected date on which such redetermination is to occur. Failure of Borrower to timely furnish such information required by Section 2.2(a) shall not preclude Bank's right to redetermine the Borrowing Base based on information previously furnished to Bank. Bank shall promptly notify in writing Borrower of the new Borrowing Base. Any redetermination of the Borrowing Base shall not be effective until written notice is sent to Borrower. 17 Page 13 (c) In the event the aggregate unpaid principal amount of all Advances, shall, at any time, be in excess of the amount of the Borrowing Base in effect at such time, then Borrower shall, within thirty (30) days of such event, at the option of Borrower, subject to the approval of Bank, either (i) subject to the Bank Lien, by instruments satisfactory in form and substance to Bank, provide additional collateral with value in amounts satisfactory to Bank, in order to increase the Borrowing Base by an amount at least equal to such excess; or (ii) prepay the outstanding principal of the Note in an aggregate amount at least equal to such excess; or (iii) pay to Bank up to one hundred percent (100%) of the Net Proceeds from Production until the aggregate unpaid principal amount of all Advances, is equal to or less than the Borrowing Base then in effect. 2.3 Repayment. Accrued interest on the Advances shall be due and payable monthly commencing on June 30th and continuing on the last day of each day of each month thereafter until all Advances are paid in full. All principal and unpaid interest thereon shall be due and payable on the Commitment Termination Date. All payments received on the Advances shall be applied first to accrued interest and then to principal. 2.4 Interest. (a) Subject to Sections 2.4 (b) and (c), the principal amount of all Advances shall bear interest at a rate per annum from day to day equal to the lesser of (i) the Highest Lawful Rate in effect from day to day; or (ii) the sum of one percent (1%) plus the Prime Rate in effect from day to day (the "Contract Rate"). Each change in the rate of interest charged shall be subject to the terms of this Section 2.4, and shall become effective, without notice to Borrower, upon the effective date of each change in the Highest Lawful Rate or the Prime Rate, as the case may be. (b) Notwithstanding the foregoing, if at any time the Contract Rate exceeds the Highest Lawful Rate, any subsequent reductions in the Contract Rate shall not reduce the rate of interest hereunder below the Highest Lawful Rate until the total amount of interest accrued approximately equals (but does not exceed) the amount of interest which would have accrued if the Contract Rate had at all times been in effect. In the event that at maturity (whether stated or by acceleration) or at final payment of the Note, the total amount of interest paid or accrued on the Note is less than the amount of interest which would have accrued if the Contract Rate had at all times been in effect with respect thereto, then at such time Borrower shall pay to Bank an amount equal to the difference between (i) the lesser of the amount of interest which would have accrued if the Contract Rate had at all times been in effect and the amount of interest which would have accrued if the Highest Lawful Rate had at all times been in effect; and (ii) the amount of interest actually accrued on the Note. (c) Notwithstanding the foregoing, all past-due principal of and interest on the Note shall bear interest at a rate per annum from day to day equal to the lesser of (i) the 18 Page 14 Highest Lawful Rate in effect from day to day; or (ii) the Prime Rate plus 5% (the "Default Rate"), from maturity (whether stated or by acceleration) until paid. (d) Each determination of the Contract Rate or the Default Rate shall be on the basis of actual days elapsed but computed as if each calendar year consisted of 360 days; unless such calculation would result in a usurious rate, in which case the rate shall be calculated on a year based upon 365 or 366 days, as the case may be. Each such determination shall, in the absence of an arithmetic or clerical error, be conclusive. 2.5 Voluntary Prepayments. Borrower shall be entitled to prepay the Advances from time to time and at any time, in whole or in part, without penalty; provided that unless Borrower and Bank otherwise agree in writing (a) all accrued interest and any and all fees and other sums then due and payable to Bank under the Loan Documents shall be paid; (b) a prepayment shall be applied to installments of principal of the Advances in inverse order of maturity; (c) any partial prepayment must be at least $100,000 and must be an integral multiple of $25,000; and (d) Borrower must have given Bank one (1) Business Day prior written notice of the intention to prepay any part of the Advances. 2.6 Manner and Application of Payments and Prepayments. Each payment or prepayment of interest or principal on the Advances must be paid at Bank's principal office in Houston, Texas, in funds which are or will be available for immediate use by Bank by 12:00 noon Central Time on the day such payment or prepayment is due. In any case, where a payment of principal of or interest on the Advances is due on a day which is not a Business Day, Borrower shall be entitled to delay such payment until the next succeeding Business Day, but interest shall continue to accrue at the rate then effective under the Note until the payment is in fact made. 2.7 Mandatory Prepayments. If, at any time, the sum of the outstanding principal balance under the Note exceeds the Borrowing Base, or if at any time the Borrower has knowledge that the sum of the outstanding principal balance under the Note exceeds the Borrowing Base, then Borrower shall forthwith prepay the amount of such excess for application towards reduction of the outstanding principal balance of the Note. Such prepayment shall be with no premium or penalty, and shall be made together with the payment of accrued interest on the amount prepaid. 2.8 Capital Adequacy. If either (i) the introduction of or any change in or in the interpretation of any Law or regulation; or (ii) compliance by Bank with any guideline or request from any central bank or other Tribunal (whether or not having the force of Law) affects or would affect the amount of capital required or expected to be maintained by Bank or any corporation controlling Bank and Bank determines that the amount of such capital is increased by or based upon the existence of Bank's obligations and commitments hereunder and other obligations and commitments of this type, then, upon demand by Bank, Borrower shall 19 Page 15 immediately pay to Bank, from time to time as specified by Bank, additional amounts sufficient to compensate Bank in the light of such circumstances, to the extent that Bank reasonably determines that such increase in capital to be allocable to the existence of Bank's obligations and commitments hereunder. A certificate as to such amounts submitted to Borrower by Bank, shall, in the absence of manifest error, be conclusive and binding for all purposes. 2.9 Facility Fee. At Closing, Borrower shall pay to Bank a Facility Fee equal to one percent (1%) of the initial Borrowing Base. Thereafter, Borrower shall pay to Bank a Facility Fee equal to one percent (1%) of any increase in the Borrowing Base as redetermined from time to time. 2.10 Commitment Fee. From the date hereof until the Commitment Termination Date, Borrower shall pay to Bank a commitment fee, as it accrues on the tenth (10th) day of each July, October, January, and April equal to one-half of one percent (1/2%) per annum (calculated on the basis of actual days elapsed, but computed as if each calendar year consisted of 360 days) on the daily average difference, during the preceding calendar quarter or portion thereof preceding such payment date, between Borrowing Base in effect for such calendar quarter and the principal amount outstanding under the Note. 2.11 Use of Proceeds. Borrower may use the proceeds of the Advances to refinance Debt in favor of Stratum under the Stratum Documents; finance future acquisitions, working capital and other general corporate purposes. ARTICLE 3. COLLATERAL 3.1 Bank Lien in Collateral. The full and complete payment and performance of the Obligation shall be secured under the Security Instruments by first and prior Bank Liens in, to and on all of Borrower's respective Rights, titles and interests in and to (but none of Borrower's obligations with respect to) the following items and types of property (the "Collateral"), all as more particularly set forth and described in the Security Instruments: (a) All present and future Rights, titles and interests that Borrower may now have or hereafter acquire in and to the Oil and Gas Properties, including, but not limited to, oil and gas and/or oil, gas and mineral leases and interests, royalty and overriding royalty interests, production payment and net profits interests, mineral fee interests, and Rights therein, including, without limitation, all reversionary or carried interests relating to the foregoing, together with all present and future Rights, titles and interests in and to all present and future unitization, communitization and pooling agreements (and all properties covered and units created thereby), whether arising by contract or operation of Law, which now or hereafter include all or any part of the foregoing and together with all lands now or hereafter subject to any of the foregoing, and all tenements, hereditaments, appurtenances, and properties in anywise appertaining, belonging, 20 Page 16 affixed or incidental to any of the foregoing.

The Bank Liens in the Collateral shall be further evidenced and governed by the Security Instruments. 3.3 Proceeds Account. The Security Instruments contain an assignment by Borrower to Bank of all production of Borrower's Hydrocarbons and all proceeds attributable thereto properly allocable to the Oil and Gas Properties of Borrower. Borrower and Bank hereby agree to open an account with Bank into which all such proceeds from the production of Hydrocarbons shall be deposited (the "Proceeds Account"). Borrower hereby grants to Bank, subject to the prior assignment in favor of Bank of Borrower's production and its proceeds, a security interest in that portion of the Proceeds Account attributable to the Hydrocarbon Interests. Notwithstanding the foregoing, Borrower may, until Bank shall give notice to the contrary, have access to all such proceeds in the Proceeds Account.

THE RELATIONSHIP ESTABLISHED BETWEEN THEM IN CONNECTION WITH THIS AGREEMENT, AND WHETHER ARISING IN CONTRACT, TORT, EQUITY OR OTHERWISE, SHALL BE RESOLVED ONLY BY THE TERMS AND PROVISIONS OF THE CURRENT ARBITRATION PROGRAM OF BANK WHICH IS ATTACHED HERETO AS EXHIBIT 8.4(b) AND IS INCORPORATED HEREIN BY REFERENCE, PURSUANT TO WHICH ANY AND ALL DISPUTES SHALL BE RESOLVED BY MANDATORY BINDING ARBITRATION UPON THE REQUEST OF ANY PARTY. 8.5 Interest. It is the intention of the Parties to comply with applicable usury Laws; accordingly, it is agreed that notwithstanding any provisions to the contrary in any Loan Document, in no event shall any Loan Document permit the collection of interest in excess of the maximum amount permitted by such Laws. If any such excess of interest is contracted for, charged or received under any Loan Document or if the maturity of the Obligation is accelerated in whole or in part, or in the event that all or part of the principal or interest of the Obligation shall be prepaid, so that under any of such circumstances the amount of interest contracted for, charged or received under any Loan Document on the amount of principal actually outstanding from time to time under the Obligation shall exceed the maximum amount of interest permitted by applicable usury Laws, then in any such event (a) the provisions of this Section 8.5 shall govern and control; (b) no Person now or hereafter liable for the payment of the Obligation shall be obligated to pay the amount of such interest to the extent that it is in excess of the maximum amount of interest permitted to be contracted for by, charged to or received from the Person obligated thereon under the applicable usury Laws; (c) any such excess which may have been collected shall be either applied as a credit against the then unpaid principal amount on the Obligation or refunded to the Person paying the same, at the holder's option; and (d) the effective rate of interest shall be automatically reduced to the maximum lawful rate of interest permitted to be contracted for by, charged to or received from the Person obligated thereon under the applicable usury Laws as now or hereafter construed by the courts having jurisdiction thereof. To the extent the Laws of the State of Texas are applicable for purposes of determining the "Highest Lawful Rate," such term shall mean the "indicated rate ceiling" from time to time in effect under Article 1.04, Title 79, Revised Civil Statutes of Texas, 1925, as amended, or, if permitted by applicable Law and effective upon the giving of the notices required by such Article 1.04 (or effective upon any other date otherwise specified by applicable Law), the "monthly ceiling," the "quarterly ceiling," or "annualized ceiling" from time to time in effect under such Article 1.04, whichever Bank shall elect to substitute for the "indicated rate ceiling," and vice versa, each such substitution to have the effect provided in such Article 1.04; and Bank shall be entitled to make such election from time to time and one or more times and, without notice to Borrower, to leave any such substitute rate in effect for subsequent periods in accordance with subsection (h)(1) of such Article 1.04. Pursuant 42 Page 38 to Article 15.10(b) of Chapter 15, Subtitle 79, Revised Civil Statutes of Texas, 1925, as amended, Borrower agrees that such Chapter 15 shall not govern or in any manner apply to the Obligation. 8.6 INDEMNIFICATION. BORROWER HEREBY INDEMNIFIES BANK AND EACH AFFILIATE THEREOF AND THEIR RESPECTIVE OFFICERS, DIRECTORS, EMPLOYEES, ATTORNEYS, AND AGENTS FROM, AND HOLDS EACH OF THEM HARMLESS AGAINST, ANY AND ALL LOSSES, LIABILITIES, CLAIMS, DAMAGES, PENALTIES, JUDGMENTS, COSTS, AND EXPENSES (INCLUDING ATTORNEYS' FEES) TO WHICH ANY OF THEM MAY BECOME SUBJECT DIRECTLY OR INDIRECTLY ARISE FROM OR RELATE TO (A) THE NEGOTIATION, EXECUTION, DELIVERY, PERFORMANCE, ADMINISTRATION, OR ENFORCEMENT OF ANY OF THE LOAN DOCUMENTS, (B) ANY OF THE TRANSACTIONS CONTEMPLATED BY THE LOAN DOCUMENTS, (C) ANY BREACH BY ANY OBLIGATED PARTY OF ANY REPRESENTATION, WARRANTY, COVENANT, OR OTHER AGREEMENT CONTAINED IN ANY OF THE LOAN DOCUMENTS, (D) THE PRESENCE, RELEASE, THREATENED RELEASE, DISPOSAL, REMOVAL, OR CLEANUP OF ANY HAZARDOUS SUBSTANCE LOCATED ON, ABOUT, WITHIN, OR AFFECTING ANY OF THE PROPERTIES OR ASSETS OF BORROWER OR ANY SUBSIDIARY, OR (E) ANY INVESTIGATION, LITIGATION, OR OTHER PROCEEDING, INCLUDING, WITHOUT LIMITATION, ANY THREATENED INVESTIGATION, LITIGATION, OR OTHER PROCEEDING RELATING TO ANY OF THE FOREGOING OR RELATING TO ANY OF THE INVENTORY PRODUCED OR SOLD BY BORROWER. WITHOUT LIMITING ANY PROVISION OF THIS AGREEMENT OR OF ANY OTHER LOAN DOCUMENT, IT IS THE EXPRESS INTENTION OF THE PARTIES THERETO THAT EACH PERSON TO BE INDEMNIFIED UNDER THIS SECTION SHALL BE INDEMNIFIED FROM AND HELD HARMLESS AGAINST ANY AND ALL LOSSES, LIABILITIES, CLAIMS, DAMAGES, PENALTIES, JUDGMENTS, COSTS, AND EXPENSES (INCLUDING ATTORNEY'S FEES) ARISING OUT OF OR RESULTING FROM THE SOLE OR CONTRIBUTORY NEGLIGENCE OF THE PERSON TO BE INDEMNIFIED. THE OBLIGATIONS OF BORROWER UNDER THIS SECTION SHALL SURVIVE THE REPAYMENT OF THE OBLIGATIONS. 8.7 Severability. If any provision of any of the Loan Documents is held to be illegal, invalid or unenforceable under present or future Laws effective during the term thereof, such provision shall be fully severable; the appropriate Loan Document shall be construed and enforced as if such illegal, invalid or unenforceable provision had never comprised a part thereof; and the remaining provisions thereof shall remain in full force and effect and shall not be affected by the illegal, invalid or unenforceable provision or by its severance therefrom. Furthermore, in lieu of such illegal, invalid or unenforceable provision, there shall be added automatically as a part of such Loan Document a provision as similar in terms to such illegal, invalid or unenforceable 43 Page 39 provision as may be possible and be legal, valid and enforceable. 8.8 Entire Agreement. This instrument embodies the entire agreement among the Parties with respect to the subject matter hereof, supersedes all prior agreements and understandings, if any, relating to the subject matter hereof, and may be amended only by an instrument in writing executed jointly by authorized officers of Borrower and Bank, and supplemented only by documents delivered or to be delivered in accordance with the express terms hereof. 8.9 Multiple Counterparts. This Agreement may be executed in a number of identical counterparts, each of which shall be deemed an original for all purposes and all of which constitute, collectively, one agreement; but, in making proof of this Agreement, it shall not be necessary to produce or account for more than one such counterpart. 8.10 Successors. This Agreement shall be binding upon and inure to the benefit of Borrower and Bank and their respective successors and assigns. Borrower expressly recognizes and agrees that Bank may sell to other financial institutions interests in the Loans incurred by Borrower hereunder, and may in connection therewith, assign to such financial institutions any Right, Bank Lien, or any part thereof created or arising out of any Loan Document. 8.11 Survival of Representations. All representations and warranties herein contained or made in writing in connection with this Agreement shall survive the execution and delivery of this Agreement and the making of the Loans hereunder and shall continue in full force and effect until the Obligation shall have been paid in full. 8.12 NO ORAL AGREEMENTS. THIS WRITTEN LOAN AGREEMENT AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES. 44 Page 40 IN WITNESS WHEREOF, the Parties have caused this Agreement to be duly executed and delivered by their proper and duly authorized officers as of the day and year first above written.
