Subject to the terms of this Agreement, Seller agrees to and does hereby issue, sell and deliver the Note and the Warrants to Purchaser at the Closing (as defined herein), and Purchaser agrees to and does hereby purchase and accept the Note and the Warrants from Seller. 1.2 Consideration for Purchase of the Note. Subject to the terms of this Agreement, Purchaser hereby agrees to pay to Seller, by check or wire transfer to the account of Black Warrior, $10,000,000, as the consideration for the purchase of the Note (the "Note Consideration"). It is the intention of the parties that the Note Consideration shall be advanced in multiple advances, with $1,000,000 being paid at the time of the execution of the Asset Purchase Agreement (the "Phoenix Agreement") between Seller and Phoenix Drilling Services, Inc., and an additional $1,000,000 being paid on March 1, 1998 if the acquisition made the subject of the Phoenix Agreement has not been closed by such date. Interest under the Note shall accrue on amounts actually advanced. 1.3 Consideration for Purchase of the Warrants. Subject to the terms of this Agreement, Purchaser hereby agrees to pay to Seller, by check or wire transfer to the account of Black Warrior, $100,000 (or $0.05 per share subject to the Warrants) as the consideration for the purchase of the Warrants (the "Warrant Consideration"; the Note Consideration and the Warrant Consideration are collectively referred to herein as the "Consideration"). It is the intention of the parties that the Warrant Consideration shall be paid in multiple payments with $10,000 being paid at Closing, and with $1,000 being paid for each additional $100,000 advanced by Purchaser to Seller hereunder. 1.4 Origination Fee. Seller agrees to pay Purchaser at Closing a one-time origination fee in the amount of $125,000 (the "Origination Fee") for the payment of the Note Consideration. 1.5 Subordination to Future Financing. Purchaser agrees to enter into subordination agreements with senior secured lenders that provide financing to Seller in an amount not to exceed $4,500,000 with respect to a term loan and $3,000,000 with respect to a revolving credit facility (in this section, the "Senior Lenders"), pursuant to which Purchaser would subordinate its security interests and rights to the security interests of the Senior Lenders. Such subordination agreements shall be on terms and conditions acceptable to all parties (including Purchaser, which agrees to negotiate in good faith with respect to the subordination agreement) at the time they are entered into. Such subordination agreements shall not obligate Purchaser to "stand still" for a period of time longer than 60 days after a default by Seller in its obligations to the Senior Lender(s). 1.6 Future Financings. If Seller, at any time so long as the Note is outstanding, intends to issue or sell any shares of capital stock, debt securities or securities convertible into, exchangeable for or exercisable for shares of capital stock or debt securities (a "Financing"), Seller shall give Purchaser written notice (the "Offer") of its intent to engage in a Financing, specifying its basic terms and conditions. If Purchaser gives notice to Seller, specifying Purchaser's basic terms and conditions, of its intent to provide Financing on a basis materially similar to the proposal set forth in the Offer within five (5) business days after receipt of the Offer (a "Financing Notice"), then Seller shall be obligated to 2 consummate the Financing only with Purchaser and Purchaser shall be obligated to provide the financing at the time committed by the third party whose commitment gave rise to the Offer. If Purchaser does not within five (5) business days after receipt of the Offer give to Seller a Financing Notice, Purchaser shall be deemed to have waived its rights to provide the Financing under this Section, and Seller may thereafter obtain such Financing from a third party or parties if such third party Financing is on the same basic terms and conditions as those set forth in the Offer. Any proposed Financing on terms materially different from those basic terms and conditions in the Offer deemed waived by Purchaser shall require a new Offer and compliance by Seller with the provisions of this Section. Notwithstanding the foregoing, Seller shall not be required to comply with this Section in connection with: (i) the issuance and sale of Common Stock or convertible securities in connection with any employee stock option plan, arrangement or agreement now or hereafter in effect; (ii) the issuance of capital stock of Seller upon exercise of the Warrants or otherwise issued to Purchaser or its assigns; (iii) the issuance of capital stock upon exercise of any stock purchase warrant or option (other than the options referred to in clause (i) above) or other convertible security outstanding on the date hereof or hereafter issued; (iv) a public offering of securities; (v) any loan from a regular commercial lending source; or (vi) any securities issued with the favorable vote of Purchaser's designee as a director of the Seller. 1.7 Other Permitted Debt.

The execution and delivery of the Transaction Documents do not, and the consummation of the transactions contemplated hereby and thereby will not, conflict with or result in a breach of or the acceleration of any obligation under, or constitute a default or event of default (or event which, with notice or lapse of time or both, would constitute a default or event of default) under, any provision of any charter, bylaw, indenture, mortgage, lien, lease, agreement, contract, instrument, order, judgment, decree, ordinance or regulation, or any restriction to which any property of Seller is subject or by which Seller is bound, the effect of which would be materially adverse to Seller. Seller is not, nor does Seller have knowledge that it is alleged to be, in material violation or default of any applicable law, statute, order, rule or regulation promulgated or judgment entered by any court, administrative agency or commission or other governmental agency or instrumentality, domestic or foreign (a "Governmental Entity"), relating to or affecting the operation, conduct or ownership of the property or business of Seller. 2.3 Approvals.

All of the Common Stock issued on the exercise of the Warrants will be fully paid, non-assessable and free and clear of any 5 Encumbrances. As used in this Agreement, the term "Encumbrance" means and includes (i) any security interest, mortgage, deed of trust, lien, charge, pledge, proxy, adverse claim, equity, power of attorney, or restriction of any kind, including but not limited to, any restriction or servitude on the use, transfer, receipt of income, or other exercise of any attributes of ownership, and (ii) any Uniform Commercial Code financing statement or other public filing, notice or record that by its terms purports to evidence or notify interested parties of any of the matters referred to in clause (i) that has not been terminated or released by another proper public filing, notice or record. 2.8 Subsidiaries.

Except as set forth in Schedule 2.8, all outstanding shares of capital stock of the Active Subsidiary were duly and validly issued and are fully paid, nonassessable and owned by Seller or a subsidiary of Seller, free and clear of all Encumbrances. There are no options, warrants or other rights, agreements or commitments (including preemptive rights) obligating Seller or the Active Subsidiary to issue, to sell or to transfer any shares of capital stock or other securities of the Active Subsidiary.
