Seller desires to sell the Stock, and Purchaser desires to purchase the same, upon and subject to the terms and conditions set forth in this Agreement. NOW, THEREFORE, in consideration of the premises, the mutual representations, warranties, and covenants which are hereinafter set forth, and other good and valuable consideration, the legal sufficiency of which are hereby acknowledged, the parties hereto have agreed and do hereby agree as follows: ARTICLE I PURCHASE AND SALE Section 1.01 THE STOCK. Subject to all of the terms and conditions of this Agreement, Seller hereby agrees to sell, transfer, and deliver, and Purchaser hereby agrees to purchase, pay for, and accept, at the Closing (hereinafter defined), all of the Stock. Section 1.02 PRE-CLOSING DISTRIBUTION OF CERTAIN ASSETS.

In connection with such distribution, upon Closing, Seller agrees to indemnify and hold the Company and Purchaser harmless from and against any and all claims, demands, causes of action, liabilities, losses, and/or expenses (including, without limitation, reasonable attorneys' fees and other expenses of litigation) arising from or in connection with the acquisition, ownership, operation, use, or distribution of the Excluded Assets by the Company, specifically including, without limitation, any adverse tax consequences occasioned to or suffered by the Company or Purchaser as a consequence of the distribution of the Excluded Assets to Seller pursuant to this Section 1.02. 2 Section 1.03 PURCHASE PRICE.

Pending Closing, Purchaser shall have the right to inspect, review, and audit the assets of the Company and all books, records, data, and other information of Seller and the Company relating to the business and financial affairs of the Company, the title to and ownership of the assets of the Company, and the conduct of the Business. All expenses incurred by the Purchaser relating to its inspections, reviews, and audits shall be borne and paid exclusively by the Purchaser. Seller and the Company shall cooperate with Purchaser in all reasonable respects in facilitating such inspections, reviews, and audits. Without limiting the foregoing, Seller and the Company agree that, during the Inspection Period and thereafter until Closing, they will (a) provide or cause to be provided to Purchaser and its counsel, accountants, consultants, and other authorized representatives, during normal business hours or otherwise, if necessary, full access to all of their, assets, books, agreements, commitments and records; and (b) furnish Purchaser and its representatives with such data, records, and other information concerning any of their operations and affairs as Purchaser may reasonably request. Seller further agrees that, upon request by Purchaser following Closing, he will execute and deliver to Purchaser or its accountants such audit response letters and further confirmations as Purchaser or its accountants may reasonably require for purposes of verification of the accuracy, validity, and completeness of all financial and other information provided or made available by Seller and the Company to Purchaser in connection with the transactions contemplated by this Agreement. Section 5.02 EXCLUSIVE DEALING. Unless and until this Agreement shall have been terminated in accordance with the terms hereof, neither Seller nor the Company shall directly or indirectly, solicit, initiate, or participate in negotiations with, or provide any information to, any corporation, partnership, person or other entity or group (other than the Purchaser or an affiliate or an associate of the Purchaser) concerning, or enter into any agreement providing for any sale of the assets of the Company, any sale of shares of capital stock in the Company, or any similar transactions involving the Company. Section 5.03 CONSENTS, APPROVALS, AND FILINGS. Seller, the Company, and Purchaser shall each use its reasonable efforts to obtain at the earliest practicable date and, in any event, prior to the Closing Date, all consents and approvals, including any third party consents, and to make all filings - -------------------------------------------------------------------------------- STOCK PURCHASE AGREEMENT Page 13 14 required to be obtained or made under any federal, state, or local laws or any agreement or other instrument (including, without limitation, any consent or approval necessary to avoid the loss of any rights under any agreement) prior to consummating the transactions contemplated hereby, whether such consent, approval or filing is to be obtained from or made with private parties or applicable governmental authorities. Section 5.04 BROKERS AND FINDERS. Purchaser, on the one hand, and Seller and the Company, on the other hand, shall indemnify each other and hold each other harmless from any claim against the other for a broker's or finder's fee, commission, or other like payment in connection with the transactions contemplated by this Agreement which arises from or is based upon arrangements made by or through the indemnifying party. Section 5.05 PUBLIC ANNOUNCEMENTS.

Section 5.07 NOTICE OF DEVELOPMENTS. Prior to the Closing, Seller and the Company will give prompt notice to Purchaser of any material event affecting the assets, liabilities, business, financial condition, operations, results of operations, or future prospects of the Company. No disclosure pursuant to this Section 5.07 shall, however, be deemed to amend or supplement this Agreement or the schedules hereto or to prevent or cure any misrepresentation, breach of warranty, or breach of covenant under this Agreement. Section 5.08 PRELIMINARY AND FINAL COMPUTATIONS OF NFA. As part of its diligence processes in this transaction, Purchaser intends to have the books and records of the Company audited by certified professional accountants and to have audited financial statements prepared for the Company in compliance with generally accepted accounting principles ("GAAP"). Prior to Closing, Seller and Purchaser shall have their respective accounting groups perform audit work of the Company, with each to bear its own accounting and other expenses incident thereto. If there is a difference in the financial statements, the parties will try to reconcile the differences prior to Closing, it being recognized that the financial data necessary to permit a final computation of NFA may not be available at such time. The parties accordingly agree to estimate NFA at Closing utilizing the audit opinions of both accounting groups and to finalize their calculation of NFA on a post-Closing basis within sixty (60) days following the Closing. At least three (3) business days prior to the Closing, Purchaser shall deliver to Seller, and Seller shall deliver to Purchaser, a preliminary settlement statement, reflecting their good faith estimates of NFA as of the Closing Date based upon the best information then available to them. Upon receipt of these preliminary settlement statements, Seller and Purchaser shall attempt to reconcile any differences they may have regarding - -------------------------------------------------------------------------------- STOCK PURCHASE AGREEMENT Page 14 15 the same. If there are any items the parties are unable to reconcile prior to Closing, Purchaser's position shall prevail to enable Closing to proceed, but without prejudice to the right of either party to dispute any item of the final settlement statement. Within forty-five (45) days after the Closing Date, Purchaser shall deliver to Seller an audited balance sheet of the Company for the period ended as of the Closing Date, prepared in accordance with GAAP, and a proposed final settlement statement including Purchaser's final computation of NFA. Seller shall have ten (10) days from its receipt of the such balance sheet and proposed settlement statement to notify Purchaser of its objections, if any, to the information set forth therein, including the opportunity of Seller to have independent auditing or to employ the Company's auditors to prepare a final computation of NFA on behalf of Seller. If Seller fails to timely notify Purchaser of any such objections, Seller shall be deemed to have irrevocably accepted the computations and substance of such balance sheet and proposed final settlement statement for all purposes of this Agreement. If Seller timely and properly contests any items within such balance sheet or proposed final settlement statement, Seller and Purchaser shall promptly meet and utilize their best efforts to resolve their differences, it being the intention of the parties to finalize all post-Closing adjustments within sixty (60) days following the Closing Date. If the parties are unable to reach final agreement on any such post-Closing matters, they shall resolve their differences by means of the dispute resolution procedures set forth in Section 10.02 and final settlement between the parties shall be deferred pending conclusion of such procedures. At the conclusion of the post-Closing accounting contemplated by this Section 5.08, Seller or Purchaser, as appropriate, shall immediately remit to the other, in immediately available funds, the net sum determined owning by such party in the final settlement statement, whether finalized by agreement of the parties or through dispute resolution processes. As used in this Agreement, "Final Balance Sheet" and "Final Settlement Statement" shall mean the final balance sheet and the final settlement statement proposed by Purchaser, as the same may be modified either by agreement of the parties or dispute resolution pursuant to the foregoing. Section 5.09 ACCOUNTS RECEIVABLE. Seller expressly represents and warrants that all accounts receivable of the Company reflected on the Final Balance Sheet as of the Closing Date are collectible in the normal course of business within 150 days from the Closing Date without resort to litigation or the retention of collection services. Following Closing, the Company shall apply partial payments by customers to the respective outstanding receivables of such customers in the order of their aging (i.e. older accounts paid first). To the extent any such receivables remain unpaid following such 150-day period, Purchaser and the Company shall first offset the face amount of such unpaid receivables against the unpaid principal balance of the Note, if any, and, to the extent of any deficiency, may then require Seller to immediately purchase the remaining unpaid receivables from the Company at full face value and without subsequent recourse of any kind upon the Company or Purchaser. Section 5.10 TAXES AND TAX RETURNS. Seller shall be responsible for the timely preparation and filing (without extension, unless otherwise agreed by Purchaser in writing) of all federal, state, and local Tax Returns covering or for (or based upon income received or realized during) all periods prior to the end of the April 30, 2000 fiscal year of the Company. Purchaser shall be responsible for the timely preparation and filing (without extension, unless otherwise agreed by - -------------------------------------------------------------------------------- STOCK PURCHASE AGREEMENT Page 15 16 Purchaser in writing) of all federal, state, and local Tax Returns covering or for (or based upon income received or realized during) all periods following the end of the April 30, 2000 fiscal year of the Company. Seller shall prepare all such Tax Returns for which Seller is responsible in accordance with applicable law and shall submit such Tax Returns to the Company and Purchaser for their review and concurrence at least ten (10) business days prior to filing. If, after the Closing Date, any applicable taxing authority shall determine there to be a deficiency in the amount of any federal, state, or local Tax paid or payable by the Company which is not reserved for or reflected on the Final Balance Sheet and which relates to any period prior to the Closing Date, Seller shall be fully responsible for the payment of any such deficiency. Following Closing, if any Tax Return covering a period of time prior to the Closing Date shall be audited by an applicable taxing authority, the Company shall promptly notify Seller of such audit. Seller and Purchaser and the Company shall jointly conduct all discussions and negotiations with applicable taxing authorities regarding each such audited Tax Return as it may relate to periods prior to the Closing Date and any decision to compromise, settle, or pay a disputed matter under any such audited Tax Return shall require joint approval of Seller and Purchaser and the Company, which rights of negotiation and approval shall in all events between the parties be exercised in good faith. The Company shall have exclusive authority to conduct all discussions and negotiations with applicable taxing authorities regarding Tax Returns relating to periods from and after the Closing Date and shall be solely responsible for the payment of all Taxes attributable to such periods. Section 5.11 EMPLOYMENT MATTERS. To the extent Purchaser or the Company shall elect to continue the employment of current employees of the Company following Closing, each employee so retained by Purchaser or the Company following Closing shall be eligible for participation in Purchaser's current employee benefit programs with full credit for length of service prior to Closing with the Company. Seller and the Company acknowledge and agree that the decision to hire any current employees of the Company is solely in the discretion of Purchaser and that Purchaser has no obligation of any kind to employ any of the existing employees of the Company following Closing. Section 5.12 INDEMNIFICATION. (a) Indemnification by Seller. Seller agrees to indemnify and hold harmless Purchaser and the Company after the Closing Date against and in respect of any of the following matters which may be asserted or established: (i) All liabilities of the Company of any nature, whether accrued, absolute, contingent, or otherwise, which existed as of the Closing Date and are not provided for or reflected in the Final Balance Sheet; (ii) Any and all damages, losses, expenses, or deficiencies resulting from any breach of the warranties, representations and covenants of Seller and the Company contained herein or in any schedule hereto; and - -------------------------------------------------------------------------------- STOCK PURCHASE AGREEMENT Page 16 17 (iii) All demands, assessments, judgments, costs, and expenses (including reasonable legal fees and other expenses of litigation, both at the trial and appellate level) arising from or in connection with any action, suit, proceeding, or claim incident to any of the foregoing. (b) Indemnification by Purchaser.

Section 5.13 RELEASE AND WAIVER BY SELLER. Any provisions of this Agreement to the contrary notwithstanding, following Closing hereunder, Seller shall have no right of contribution, indemnity, reimbursement, or other legal or equitable right of recourse upon the Company based upon or attributable to the breach or non-performance by Seller or the Company of any of their jointly made representations, warranties, and covenants under this Agreement, and Seller, as of Closing hereunder, expressly releases and waives any and all such rights of contribution, indemnity, reimbursement or other recourse upon or against the Company. Section 5.14 INVESTMENT REPRESENTATIONS BY SELLERS. Upon Closing and in connection with any conversion of the unpaid balance of the Note into common stock of Purchaser as more particularly provided in the Note, Seller expressly represents, warrants, acknowledges, and agrees to and with Purchaser and the Company that: (a) any such stock so acquired by Seller (the "Stock") may not have been registered under the Securities Act of 1933 or any other state securities laws (collectively, the "Securities Acts") because Purchaser may or will issue the Stock in reliance upon this Section 5.16 and the exemptions from the registration requirements of the Securities Acts providing for issuance of securities not involving a public offering; (b) Seller will acquire any Stock for Seller's own account, for investment, and not with a view to the resale or distribution thereof; (c) Seller will not transfer, sell or offer for sale any portion of the Stock unless there is an effective registration or other qualification relating thereto under the Securities Act of 1933 and under any applicable state securities laws or - -------------------------------------------------------------------------------- STOCK PURCHASE AGREEMENT Page 17 18 unless the holder of the Stock delivers to Purchaser an opinion of counsel, satisfactory to Purchaser, that such registration or other qualification under such Act and applicable state securities laws is not required in connection with such transfer, offer or sale; (d) Purchaser is under no obligation to register the Stock or to assist Seller in complying with any exemption from registration under the Acts if Seller should at a later date wish to dispose of the Stock; (e) Prior to entering into this Agreement, Seller has made an investigation of Purchaser and its business and has obtained or had made available to Seller all information with respect thereto which Seller needed to make an informed decision to structure the transactions contemplated hereby as provided in this Agreement; (f) Seller possesses adequate experience and sophistication as investors for the evaluation of the merits and risks of investment in the Stock; and (g) Seller is an "accredited investor," as defined in Regulation D as promulgated under the Securities Act of 1933, as amended, (the "1933 Act").

O. Box 880, Eunice, New Mexico 88231, the principal sum of FOUR HUNDRED THOUSAND AND NO/100 DOLLARS ($400,000.00), together with interest on the unpaid principal balance from day to day outstanding prior to default or maturity at per annum rate 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). 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 rate of interest denominated and published as such by the Wall Street Journal on the first Friday most immediately preceding the date of this Note that is a business day. 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. The principal of and accrued interest on this Note are due and payable one year from the date hereof. 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 Eunice Well Servicing, Inc., as Grantor, and Payee, as Secured Party, covering all of the equipment and other tangible personal property 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. - -------------------------------------------------------------------------------- STOCK PURCHASE AGREEMENT Page 33 33 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. Any provisions of this Agreement to the contrary notwithstanding, if Maker shall successfully conclude an initial public offering of common stock in Maker through a nationally recognized stock exchange at any time prior to maturity of this Note, whether stated or by acceleration, (the "Sierra IPO") Maker shall confer written notice thereof upon Payee and Payee shall thereupon have the right, exercisable at any time prior to maturity hereof as hereinafter provided, at its sole option, to convert the unpaid balance of this note to common stock in Maker at a per share price equivalent to the per share price at which Sierra issued its common stock in the Sierra IPO. Payee shall exercise such optional right by conferring written notice of exercise upon Maker prior to maturity hereof, whether stated or by acceleration, accompanied by the original of this note, marked "PAID," in return for which Maker shall issue the requisite number of shares of its common stock to Payee. The failure by Payee to exercise optional right in the time and manner specified shall cause such right to terminate automatically and without necessity of further action by Payee. This Note is in all respects subject to that certain Stock Purchase Agreement dated as of February 29, 2000, between Rex Busby and Madie Walker, as Seller, Eunice Well Servicing, Inc., as the Company, and Maker, as Purchaser.
