(d) Unless Lender shall otherwise state in writing, during the existence of an Event of Default, Borrower may not elect to have a Loan converted into or continued as a LIBOR Rate Loan. (e) Notwithstanding any other provision contained in this Agreement, after giving effect to any conversion or continuation of any LIBOR Rate Loans, there shall not be more than five (5) different Interest Periods in effect. 2.4 - Scheduled Amortization of the Loan.

Borrower may make optional prepayments on the outstanding principal balance of any Base Rate Loan without penalty or premium, at any time, and from time to time, in integral multiples of $100,000 or such lesser amount equal to the then outstanding balance, together with accrued and unpaid interest on the principal amount so paid. LIBOR Rate Loans may not be prepaid, except if it is necessary so that Borrower can be in compliance with Section 3.4. Borrower shall give Lender one Business Day's notice in advance of any optional payment on the Base Rate Loan, and three Business Day's notice in advance of any prepayment on the LIBOR Rate Loan required pursuant to Section 3.4. Such notices shall specify what portion of the Loan is to be prepaid and the date of prepayment. Such notices shall be irrevocable by Borrower.

(b) Interest, computed on the unpaid balance of the Note shall be due and payable as it accrues monthly, commencing on February 15, 1997 and on the same day of each and every succeeding month thereafter during the term hereof, and at maturity, October 15, 2001, when the entire amount of the Note, principal and accrued, unpaid interest, shall be due and payable. (c) Interest on the Loan shall accrue daily and shall be computed on the basis of a year of 365 or 366 days, as appropriate, for Base Rate Loans, and a year of 360 days for LIBOR Rate Loans. Interest on the Loans shall be payable in arrears on the Interest Payment Date. (d) Notwithstanding anything to the contrary contained in this Agreement, overdue principal, and (to the extent permitted under applicable law) overdue interest, whether caused by acceleration of maturity or otherwise, shall bear interest at a fluctuating rate, adjustable the day of any change in such rate, equal to the Highest Lawful Rate, until paid, and shall be due and payable immediately. 2.8 - Payments by Borrower. All payments of principal and interest hereunder shall be made at Lender's office at 500 West Texas Avenue, Midland, Texas 79701 (or at such other place as Lender shall have designated to Borrower in writing at least one Business Day prior to the due date or prepayment date, as the case may be) in immediately available funds free and clear of any and all taxes and without set-off or counterclaim or deduction of any kind. If any payment to be made by Borrower hereunder or under the Note shall become due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day and such extension of time shall be included in computing any interest and fees in respect of such payment, unless the result of such extension would be to carry any Interest Period relating to a LIBOR Rate Loan into another calendar month in which event such Interest Period shall end on the immediately preceding Business Day. 2.9 - Origination Fee. Upon execution of this Agreement and the Note, Borrower shall pay to Lender an origination fee in the amount of $15,000.00 (referred to herein as the "Origination Fee"). 2.10 - Redetermination Fee. In addition to the Origination Fee, at such time as Borrower requests an increase in the Borrowing Base, Borrower shall pay to Lender a redetermination fee in the amount of one-half of one percent (0.5%) of the amount of the requested increase (referred to herein as the "Redetermination Fee"). The parties specifically agree that the Borrower shall pay the Redetermination Fee to Lender regardless of whether Lender agrees to the increase in the Borrowing Base or whether the increase is actually funded. ARTICLE III BORROWING BASE 3.1 - Borrowing Base . The term "Borrowing Base" shall refer to an amount that is the loan value attributable, at the time in question, by Lender (acting in its sole discretion but determined in accordance with its usual and customary practices and methods and economic assumptions and standards applied generally to Lender's energy credits at the time the determination is made) to the ownership interests of the Borrower in the Mortgaged Properties that are subject to a first and prior Bank Lien and not subject to any other Liens except those permitted under the Loan Agreement. The Borrowing Base under the Loan is set at the sum of $18,000,000.00. The Borrowing Base shall reduce on a monthly basis by the Borrowing Base Reduction Amount, which Lender initially sets at the amount of $250,000.00. Borrower may request an increase in the Borrowing Base at any time. Each request shall be subject to Lender's approval, said approval to be in Lender's sole discretion and to be based upon Lender's satisfactory review of approved engineering evaluations to be submitted by Borrower or commissioned by Lender. 3.2 - Borrowing Base and Required Prepayments Under Note . As to the oil and gas properties, Lender shall redetermine the Borrowing Base at least on a semi-annual basis and may redetermine the Borrowing Base at any time in Lender's sole discretion but in accordance with the standards set forth in Section 3.3 hereinbelow. Promptly following each redetermination of the Borrowing Base, Lender shall notify Borrower of any change in the amount of the Borrowing Base or in the amount of the Borrowing Base Reduction Amount. 3.3 - Standards for Redetermination . The Borrowing Base redetermination shall be made by Lender in accordance with its usual and customary practices. In redetermining the Borrowing Base, Lender shall determine the loan value which it assigns to the oil and gas properties that are proven reserves, developed and producing and that are covered by the Deeds of Trust. As to the oil and gas properties, the loan value shall be based on Lender's engineering evaluation which utilizes Lender's then current policy for oil and gas prices, discount factors, coverage percentage and appropriate risk factors. 3.4 - Mandatory Increase in Collateral or Prepayment of Principal of the Note. In the event that the unpaid principal balance of the Note shall, at the time of notification of the Borrowing Base by Lender to Borrower, be in excess of the Commitment, Lender, acting in its sole discretion, may require Borrower to either, (i) within ten (10) business days thereafter, by instruments satisfactory in form and substance to Lender, provide Lender with additional Collateral with value in amounts satisfactory to Lender in order to increase the Borrowing Base by an amount at least equal to such excess; (ii) within ten (10) business days thereafter, prepay the principal of the Note (together with accrued interest on the principal amount so prepaid) in an amount at least equal to such excess; or (iii) amortize the overage by payments of six equal monthly installments. ARTICLE IV YIELD PROTECTION AND ILLEGALITY 4.1 - Illegality. (a) If Lender shall determine that the introduction of any law, rule or regulations, or any change in any law, rule or regulation or in the interpretation or administration thereof, has made it unlawful, or that any central bank or other governmental authority has asserted that it is unlawful, for Lender to make LIBOR Rate Loans, then, on notice thereof by Lender to Borrower, the obligation of Lender to make LIBOR Rate Loans shall be suspended until Lender shall have notified Borrower that the circumstances giving rise to such determination no longer exist. (b) If Lender shall determine that it is unlawful to maintain any LIBOR Rate Loan, and, if any LIBOR Rate Loans are then outstanding, Lender shall give notice thereof to Borrower, and within three Business Days after receipt of such notice Borrower shall elect either (A) to prepay in full all LIBOR Rate Loans of Lender then outstanding, together with interest accrued thereon, either on the last day of the Interest Period thereof if Lender may lawfully continue to maintain such LIBOR Rate Loans to such day, or immediately, if Lender may not lawfully continue to maintain such LIBOR Rate Loans, together with any amounts required to be paid in connection therewith pursuant to this Agreement, or (B) to immediately convert such LIBOR Rate Loans to Base Rate Loans in accordance with Article II of this Agreement. (c) If the obligation of Lender to make or maintain LIBOR Rate Loans has been terminated, Borrower may elect, by giving notice to Lender that all Loans which would otherwise be made by Lender as LIBOR Rate Loans shall be instead Base Rate Loans. 4.2 - Increased Costs and Reduction of Return. (a) If Lender shall determine that, due to either (i) the introduction of or any change (other than any change by way of imposition of or increase in reserve requirements included in the calculation of the LIBOR Rate) in or in the interpretation of any law or regulation or (ii) the compliance with any guideline, or request from any central bank or other governmental authority (whether or not having the force of law) issued after January 31, 1997, there shall be any increase in the cost to Lender of agreeing to make or making, funding or maintaining any LIBOR Rate Loans (other than changes in the rate of taxes on the overall net income of Lender), then Lender shall give notice of such determination to Borrower, and Borrower shall have the option either (iii) to immediately convert all outstanding LIBOR Rate Loans to Base Rate Loans in accordance with Article II or (iv) Borrower shall be liable for, and shall from time to time, upon demand therefor by Lender, pay to Lender such additional amounts as are sufficient to compensate Lender for such increased costs. If Borrower elects to convert to Base Rate Loans, it shall nevertheless be liable for any increased costs incurred by Lender regarding LIBOR Rate Loans accrued prior to the date of conversion. (b) If Lender shall have determined that (i) the introduction of any capital adequacy regulation, (ii) any change in any capital adequacy regulation, (iii) any change in the interpretation or administration of any capital adequacy regulation by any central bank or other governmental authority charged with the interpretation or administration thereof, or (iv) compliance by Lender or any corporation controlling the Lender, with any capital adequacy regulation; affects or would affect the amount of capital required or expected to be maintained by Lender or any corporation controlling Lender and (taking into consideration Lender's or such corporations' policies with respect to capital adequacy and Lender's desired return on capital) determines that the amount of such capital is increased as a consequence of its commitment to make the Loan, credits or other obligations under this Agreement, then Lender shall give notice of such determination to Borrower, and Borrower shall have the option either (v) to immediately convert all outstanding LIBOR Rate Loans to Base Rate Loans in accordance with Article II or (vi) to pay to Lender, from time to time as specified by Lender, additional amounts sufficient to compensate Lender for such increase. 4.3 - Funding Losses. Borrower agrees to reimburse Lender and to hold Lender harmless from any loss or expense which Lender may sustain or incur as a consequence of: (a) The failure of Borrower to make any payment or mandatory prepayment of principal of any LIBOR Rate Loan (including payments made after any acceleration thereof); (b) The failure of Borrower to borrow, continue or convert a Loan after Borrower has given (or is deemed to have given) a Request for Advance or a Notice of Conversion/Continuation; (c) The failure of Borrower to make any prepayment after Borrower has given a notice in accordance with Section 2.3; (d) The prepayment (including pursuant to Section 2.3) of a LIBOR Rate Loan on a day which is not the last day of the Interest Period with respect thereto; or (e) The conversion pursuant to of any LIBOR Rate Loan to a Base Rate Loan on a day that is not the last day of the respective Interest Period; including any such loss or expense arising from the liquidation or reemployment of funds obtained by it to maintain its LIBOR Rate Loans hereunder or from fees payable to terminate the deposits from which such funds were obtained. 4.4 - Inability to Determine Rates. If Lender shall have determined that for any reason adequate and reasonable means do not exist for ascertaining the LIBOR Rate for any requested Interest Period with respect to a proposed LIBOR Rate Loan or that the LIBOR Rate applicable for any requested Interest Period with respect to a proposed LIBOR Rate Loan does not adequately and fairly reflect, in Lender's reasonable judgment, the cost to Lender of funding such Loan, Lender shall forthwith give notice of such determination to Borrower. Thereafter, the obligation of Lender to make or maintain LIBOR Rate Loans, as the case may be, hereunder shall be suspended until Lender revokes such notice in writing, unless means exist for ascertaining the LIBOR Rate and Borrower agrees to pay such amount as Lender determines in its sole and absolute discretion is necessary to reflect the cost of Lender of funding such Loan. Upon receipt of such notice, Borrower may revoke any Request for Advance or Notice of Conversion/Continuation then submitted by it. If Borrower does not revoke such request or notice prior to the time that such Loan is made, Lender shall make, convert or continue the Loan, as proposed by Borrower in the amount specified in the applicable request or notice submitted by Borrower, but such Loan shall be made, converted or continued as Base Rate Loans instead of LIBOR Rate Loans. 4.5 - Certificate of Lender. If Lender claims reimbursement or compensation pursuant to this Article IV, Lender shall deliver to Borrower a certificate setting forth in reasonable detail the amount payable to Lender hereunder and such certificate shall be binding on Borrower unless Borrower objects to the contents of such certificate within five Business Days after receipt thereof.

Borrower agrees to pay all legal, engineering, and environmental fees and expenses reasonably incurred by Lender in connection with the investigation and negotiation of the financing, as well as the preparation and execution of the Loan Papers; provided, however, that all of such fees, costs, and expenses shall be credited against the Origination Fee.

In the event that Lender discovers or otherwise becomes aware of an indemnification claim arising under Section 8.8 of this Agreement, Lender shall give written notice to Borrower, specifying such claim, and may thereafter exercise any remedies available to Lender under this Agreement; provided, however, that the failure of Lender to give notice as provided herein shall not relieve Borrower of any obligations hereunder, to the extent Borrower is not materially prejudiced thereby. Further, promptly after receipt by Lender of written notice of the commencement of any action or proceeding with respect to which a claim for indemnification may be made pursuant to Section 8.8, Lender shall, if a claim in respect thereof is to be made against Borrower, give written notice to Borrower of the commencement of such action; provided however, that the failure of Lender to give notice as provided herein shall not relieve Borrower of any obligations hereunder, to the extent Borrower is not materially prejudiced thereby. In case any such action is brought against Lender, Borrower shall be entitled to participate in and to assume the defense thereof, jointly with any other indemnifying party similarly notified, to the extent that it may wish, with counsel reasonably satisfactory to Lender, and after notice from Borrower to Lender of its election so to assume the defense thereof, Borrower shall not be liable to Lender for any legal or other expenses subsequently incurred by the latter in connection with the defense thereof unless Borrower has failed to assume the defense of such claim and to employ counsel reasonably satisfactory to Lender. If Borrower elects not to assume the defenses of a claim, Borrower shall not be liable for the fees and expenses of more than one counsel in any single jurisdiction with respect to such claim or with respect to claims separate but similar or related in the same jurisdiction arising out of the same general allegations. Notwithstanding any of the foregoing to the contrary, Lender will be entitled to select its own counsel and assume defense of any action brought against it if Borrower fails to select counsel reasonably satisfactory to Lender, the expenses of such defense to be paid by Borrower. Borrower shall not consent to entry of any judgment or enter into any settlement with respect to a claim without the consent of Lender, which consent shall not be unreasonably withheld, or unless such judgment or settlement includes as an unconditional term thereof a release of Lender by the claimant or plaintiff from all liability with respect to such claim. Lender shall not consent to entry of any judgment or enter into any settlement of any such action, the defense of which has been assumed by Borrower, without the consent of Borrower, which consent shall not be unreasonably withheld. In the event that Lender becomes entitled to compensation from Borrower pursuant to the provisions of Section 8.8, any such compensation shall bear interest at that Highest Lawful Rate per annum from the date of Lender's payment of any claims until paid by Borrower and shall be part of the Obligation secured by the Bank Liens. 8.10 - Curing of Defects . Borrower will promptly cure any defects in the execution and delivery of any of the Loan Papers, and in any other instrument or document referred to or mentioned herein. Borrower will immediately execute and deliver to Lender upon request, all such other and further instruments as may be reasonably required or desired by Lender from time to time in compliance with or accomplishment of the covenants and agreements of Borrower made in the Loan Papers. 8.11 - Inspection and Visitation . Borrower will grant Lender access to all of its books and records, as well as to all of the Collateral, and allow inspection and copying of same by Lender or its designated representatives at any time during normal business hours or such other time as Lender may reasonably request; provided, however, that nothing in this Section 8.11 shall require Borrower to provide access to Lender to any books, records, or other materials covered by a confidentiality agreement that has been entered into as the result of arms-length negotiations between Borrower and an unrelated third party. 8.12 - Notices . Borrower will give prompt written notice to Lender of any proceedings instituted against it by or in any federal or state court or before any commission or other regulatory body, federal, state or local, which, if adversely determined, would cause a Material Adverse Change. 8.13 - Compliance . Borrower will observe and comply with: (a) All laws, statutes, codes, acts, ordinances, rules, regulations, directions and requirements of all federal, state, county, municipal and other governments, departments, commissions, boards, courts, authorities, officials and officers, domestic and foreign, including but not limited to all applicable regulatory requirements promulgated by any governmental agency including OSHA, the EPA, the Pension Benefit Guaranty Fund, ERISA, and any other applicable regulatory agency, where the failure to observe or comply would cause a Material Adverse Change; (b) all orders, judgments, decrees, injunctions, certificates, franchises, permits, licenses, and authorizations of all federal, state, county, municipal, and other governments, departments, commissions, boards, courts, authorities, officials, and officers, domestic and foreign, which the failure to observe or comply would cause a Material Adverse Change and against which it shall maintain such reserves as are appropriate under GAAP; and (c) GAAP in all of its accounting procedures. 8.14 - Compliance With Environmental Laws . Borrower, to the best of its knowledge, is in substantial compliance with all state and federal environmental laws and regulations and will remain in substantial compliance with same and will not place or permit to be placed any Hazardous Materials on any of its properties in violation of applicable state and federal environmental laws. In the event Borrower should discover any Hazardous Materials on any of their properties which could result in a breach of the foregoing covenant, Borrower shall notify Lender within three (3) days after such discovery. Borrower shall dispose of all material amounts of Hazardous Materials generated by it only at facilities and/or with carriers that Borrower reasonably believes maintain valid governmental permits under the Resource Conservation and Recovery Act, 42 U.S.C. ss.6901. In the event of any notice or filing of any procedure against Borrower alleging a violation of any environmental law or regulation, Borrower shall give notice to Lender within five (5) days after receiving notice of such notice or filing. 8.15 - Post-Closing Title Review. Within sixty (60) days of the execution of this Agreement, Lender shall obtain title reports covering Mortgaged Properties that represent eighty percent (80%) or more of the net proven value of Lender's most recent engineering evaluation. Such title reports shall be prepared by legal counsel of Lender's choice. The cost of such title reports shall be included in the Origination Fee. To the extent possible, the title reports will be based upon prior title opinions obtained from Borrower's files and reports prepared by landmen selected by Lender during the course of its due diligence review. Within thirty (30) days of Lender's receipt of such title reports, Borrower shall cure any title defects reported therein for which curative activity is reasonably required by Lender, acting in its sole discretion.
