DURHAM d/b/a TRINITY SERVICES ("Payee"), at P. O. Box 153, Kingsville, Texas 78364, the principal sum of TWO HUNDRED FIFTY THOUSAND AND NO/100 DOLLARS ($250,000.00), together with interest on the unpaid principal balance from day to day outstanding prior to default or maturity at a floating per annum rate which shall from quarter to quarter be equal to the lesser of (i) the Prime Rate (hereinafter defined) in effect hereunder (the "Established Rate") (calculated on the basis of actual days elapsed in a year consisting of 365 or 366 days, as appropriate) or (ii) the Maximum Rate (hereinafter defined) (calculated on the basis of actual days elapsed in a year consisting of 365 or 366 days, as appropriate). The interest rate on this Note shall initially be determined as of the first Friday most immediately preceding the date of this Note that is a business day (the "Initial Determination Date") and shall thereafter be redetermined quarterly until maturity based upon the Prime Rate in effect as of the first Friday most immediately preceding each ensuing calendar quarter from the date hereof that is a business day (each such date being hereinafter referred to as a "Redetermination Date"). Each change in the rate of interest charged hereunder shall, subject to the terms hereof, become effective, without notice to Maker, upon the applicable quarterly adjustment date (as opposed to the Redetermination Date). If at any time and from time to time the Established Rate exceeds the Maximum Rate, thereby causing the interest payable to be limited to the Maximum Rate, then any subsequent reduction in the Established Rate shall not reduce the rate of interest hereunder below the Maximum Rate until the total amount of interest accrued hereon equals the amount of interest that would have accrued if the Established Rate had at all times been in effect. All past due principal of and accrued interest on this Note shall bear interest at the Maximum Rate. As used herein, "Prime Rate" shall mean the floating rate of interest denominated and published as such by the Wall Street Journal on the Initial Determination Date and thereafter on each applicable Redetermination Date. As used herein, "Maximum Rate" shall mean the maximum non-usurious rate of interest that at any time, or from time to time, may be contracted for, taken, reserved, charged, or received under applicable law on the indebtedness evidenced by this Note, after taking into account, to the extent required by applicable law, any and all relevant payments, charges, or other amounts under this Note and all instruments securing payment of this Note. To the extent that Chapter 303 of the Texas Finance Code, as amended, is relevant for purposes of determining the Maximum Rate, Payee hereby notifies Maker that the applicable rate ceiling shall be the "applicable interest rate ceiling" from time to time in effect, as limited by Section 303.009 of the Texas Finance Code, as amended; provided, however, that to the extent permitted by applicable law, Payee reserves the right to change the applicable rate ceiling from time to time by further notice to Maker; and, provided further, that the Maximum Rate shall not be limited to the applicable interest rate ceiling under Chapter 303 if federal laws or other state laws now or hereafter in effect and applicable to this Note (and the interest contracted for, charged and collected hereunder) shall permit a higher rate of interest. The principal of this Note is due and payable fifteen (15) months from the date hereof. Interest on this note is due and payable monthly as it accrues, commencing on the first day of the first month following the month of Closing under the Asset Purchase Agreement (hereinafter defined) and continuing on the first day of each month thereafter until the entire principal balance and all accrued and unpaid interest on this note have 26 been paid in full. This Note may be prepaid in whole or in part without penalty. Partial prepayments shall be applied first to any accrued and unpaid interest and the balance remaining, if any, to principal. This Note is secured by that certain Security Agreement of even date herewith, between Maker, as Debtor, and Payee, as Secured Party, covering all of the collateral therein described. It is understood and agreed that in the event of default in the payment of this Note or any installment hereof, principal or interest, and if such default shall continue unremedied for more than ten (10) days following written notice thereof from Payee to Maker, or in the event of any default (other than non-payment of this Note) in any instrument securing payment of this Note and if such default shall continue unremedied for more than thirty (30) days following written notice thereof from Payee to Maker, the entire principal balance of and all accrued and unpaid interest on this Note shall at once become due and payable without notice, at the option of Payee. Failure by Payee to exercise this option on any one or more occasions shall not constitute a waiver of the right to exercise such option in the event of subsequent default. Except as otherwise herein expressly provided, the makers, signers, sureties, and endorsers of this Note jointly and severally waive demand, presentment, notice of dishonor, notice of intent to demand or accelerate payment hereof, diligence in collecting, grace, notice, and protest, and agree to one or more extensions for any period or periods of time and partial payments, before or after maturity, without prejudice to Payee; and if this Note shall be collected by legal proceedings or through probate or bankruptcy court, or shall be placed in the hands of an attorney for collection after default or maturity, Maker agrees to pay all costs of collection, including reasonable attorney's fees. All agreements between Maker and Payee, whether now existing or hereafter arising and whether written or oral, are hereby limited so that under no contingency, whether by reason or demand for payment or acceleration of the maturity hereof or otherwise, shall the interest contracted for, charged, or received by Payee exceed the Maximum Rate. If, for any circumstance whatsoever, interest would otherwise be payable to Payee in excess of the Maximum Rate, the interest payable to Payee hereunder shall be reduced to the Maximum Rate; and if for any circumstance Payee shall ever receive anything of value deemed interest by applicable law in excess of the Maximum Rate, then an amount equal to any such excess shall be applied to the reduction of the principal hereof and not the payment of interest, or if such excessive interest exceeds the unpaid balance of principal hereof, such excess shall be refunded to Maker. All interest paid or agreed to be paid to Payee shall, to the extent permitted by applicable law, be amortized, prorated, allocated, and spread throughout the full period until payment in full of the principal (including the period of any renewal or extension hereof) so that the interest hereon for such full period shall not exceed the Maximum Rate. This Note is in all respects subject to that certain Asset Purchase Agreement (the "Asset Purchase Agreement") dated as of February 10, 2000, between Payee, as Seller, and Maker, as Purchaser. This Note shall be governed by and construed in accordance with the laws of the State of Texas. SIERRA WELL SERVICE, INC.

If the Company at any time after the Issuance Date shall declare a dividend on its Common Stock payable in stock or other securities of the Company or of any other corporation or other entity, or in property or otherwise than in cash, to the holders of its Common Stock, the holder of a Warrant shall, without additional cost, be entitled to receive upon any exercise of a Warrant, in addition to the Common Stock to which such holder would otherwise be entitled upon such exercise, the number of shares of stock or other securities or property which such holder would have been entitled to receive if he had been a holder immediately prior to the record date for such dividend (or, if no record date shall have been established, the payment date for such dividend) of the number of shares of Common Stock purchasable on exercise of such Warrant immediately prior to such record date or payment date, as the case may be. (d) Items Constituting Common Stock. For the purposes of this Section 3, the term "shares of Common Stock" shall mean shares of (i) the class of stock designated as the Common Stock at the date hereof or (ii) any other class of stock resulting from successive changes or reclassifications of such shares consisting solely of changes in par value, or from par value to no par value, or from no par value to par value. If at any time, because of an adjustment pursuant to subsection (a), the Warrants shall entitle the holders to purchase any securities other than shares of Common Stock, thereafter the number of such other securities so purchasable upon exercise of each Warrant and the Exercise Price of such securities shall be subject to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to the Common Stock contained in this Section 3. 30 (e) Calculation of Exercise Price. The Exercise Price in effect from time to time shall be calculated to four decimal places and rounded to the nearest thousandth. 4. NOTICE OF ADJUSTMENTS. Whenever the Exercise Price or the number of shares of Common Stock is required to be adjusted as provided in Section 3, the Company shall forthwith compute the adjusted Exercise Price or the number of shares of Common Stock issuable and shall prepare and mail to the holder hereof a certificate setting forth such adjusted Exercise Price or such number of shares of Common Stock, showing in reasonable detail the facts upon which the adjustment is based. 5. NOTICES TO WARRANT HOLDERS. In the event: (a) of any consolidation or merger to which the Company is a party and for which approval of any stockholders of the Company is required, or of the conveyance or sale of all or substantially all of the assets of the Company, or of any reclassification or change of the Common Stock or other securities issuable upon exercise of the Warrants (other than a change in par value, or from par value to no par value, or from no par value to par value or as a result of a subdivision or combination), or a tender offer or exchange offer for shares of Common Stock (or other securities issuable upon the exercise of the Warrants); or (b) the Company shall declare any dividend (or any other distribution) on the Common Stock, other than regular cash dividends; or (c) the Company shall authorize the granting to the holders of Common Stock of rights or warrants to subscribe for or purchase any shares of any class or series of capital stock; or (d) of the voluntary or involuntary dissolution, liquidation or winding up of the Company; then the Company shall cause to be sent to the holder hereof, at least 30 days prior to the applicable record date hereinafter specified, or promptly in the case of events for which there is no record date, a written notice stating (x) the date for the determination of the holders of record of shares of Common Stock (or other securities issuable upon the exercise of the Warrants) entitled to receive any such dividends or other distribution, (y) the initial expiration date set forth in any tender offer or exchange offer for shares of Common Stock (or other securities issuable upon the exercise of the Warrants), or (z) the date on which any of the events specified in subsections (a)-(e) is expected to become effective or consummated, and the date as of which it is expected that holders of record of shares of Common Stock (or other securities issuable upon the exercise of the Warrants) shall be entitled to exchange such shares for securities or other property, if any, deliverable upon any such event. Failure to give such notice or any defect therein shall not affect the legality or validity of any such event, or the vote upon any such action. 6. REPORTS TO WARRANT HOLDERS.

(b) The Company shall pay all expenses, taxes (other than stock transfer taxes or charges) and other charges payable in connection with the preparation, issuance and delivery of new warrant certificates on transfer of the Warrants.

(d) All original issue taxes payable in respect of the issuance of shares of Common Stock to the registered holder hereof upon the exercise of the Warrants shall be borne by the Company; provided, that the Company shall not be required to pay any tax or charge imposed in connection with any transfer involved in the issuance of any certificate representing shares of Common Stock (and other securities) in any name other than that of the registered holder hereof, and in such case the Company shall not be required to issue or deliver any certificate representing shares of Common Stock (and other securities) until such tax or other charge has been paid or it has been established to the Company's satisfaction that no such tax or charge is due. 8. NO RIGHTS AS STOCKHOLDER.
