PRELIMINARY STATEMENTS Texoil, Inc., a Nevada corporation (the "COMPANY") and the Noteholders have entered into that certain Note Purchase Agreement, dated as of December 31, 1997 (the "NOTE AGREEMENT") whereby the Noteholders have committed to purchase $10,000,000 of Convertible Subordinated General Obligation Notes issued by the Company. It is a condition precedent to the obligation of the Noteholders to purchase the Notes under the Note Agreement that Subsidiary shall have executed and delivered this Agreement. The Subsidiary has determined that it will receive a substantial benefit if the Notes are purchased by the Noteholders from the Company under the Note Agreement. In consideration of the mutual covenants herein contained the Subsidiary and the Noteholders agree as follows: ARTICLE I DEFINITIONS, ETC. SECTION 1.01. CERTAIN DEFINED TERMS. Capitalized terms used in this Agreement and not otherwise defined herein shall have the respective meanings set forth in the Note Agreement and the Annex A attached thereto (such meanings to be equally applicable to both singular and plural forms of the terms defined). SECTION 1.02. COVENANT CONSTRUCTION. Each covenant contained herein shall be construed (absent express provision to the contrary) as being independent of each other covenant contained herein, so that compliance with any one covenant shall not (absent such an express contrary provision) be deemed to excuse compliance with any other covenant. Where any provision herein refers to action to be taken by any Person, or which such Person is prohibited from taking, such provision shall be applicable whether such action is taken directly or indirectly by such Person. SECTION 1.03. OTHER RULES OF CONSTRUCTION. The words "hereof," "herein" and "hereunder" and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement. All references herein to articles, sections, annexes, exhibits and schedules shall, unless the context requires a different construction, be deemed to be references to the articles and sections of this Agreement and the annexes, exhibits and schedules attached hereto and made a part hereof. In this Agreement, unless a clear contrary intention appears, the word "including" (and with correlative meaning "include") means including, without limiting the generality of any description preceding such term. The headings of the various articles and sections of this Agreement are for convenience only and shall not affect the meaning of the terms and conditions of this Agreement. No provision of this Agreement shall be interpreted or construed against any party solely because that party or its legal representative drafted such provision. ARTICLE II GUARANTY SECTION 2.01. GUARANTY. Subsidiary hereby unconditionally and irrevocably guarantees the full and punctual payment when due, whether at stated maturity or earlier by acceleration or otherwise, of any and all debts, liabilities and obligations of the Company now or hereafter existing under the Note Agreement or the Notes whether for principal, interest (including, without limitation, all interest that accrues after the commencement of any proceeding by or against the Company under any bankruptcy, insolvency, liquidation, moratorium, receivership, reorganization or other similar debtor relief law), fees, expenses or otherwise (such obligations being the "OBLIGATIONS"), and agrees to pay any and all reasonable costs and expenses (including counsel fees and legal expenses) incurred by the Noteholders in connection with the protection, defense or enforcement of any rights under this Agreement and any of the other Transaction Documents. SECTION 2.02. GUARANTY ABSOLUTE.

The liability of Subsidiary under this Agreement shall be absolute and unconditional irrespective of: (a) any lack of validity or enforceability of the Note Agreement, the Notes, the other Transaction Documents or any other agreement or instrument relating thereto (unless such invalidity or unenforceability results from a failure of consideration on the part of the Noteholders); (b) any change in the time, manner or place of payment of, or in any other term of, all or any of the Obligations, or any other amendment or waiver of or any consent to departure from the Note Agreement, the Notes or the other Transaction Documents; (c) any taking, exchange, release or non-perfection of any collateral, or any release or amendment or waiver of or consent to departure from any other guaranty, for all or any of the Obligations; (d) any manner of application of collateral, or proceeds thereof, to all or any of the Obligations, or any manner of sale or other disposition of any collateral for all or any of the Obligations or any other assets of the Company; (e) any change, restructuring or termination of the corporate structure or existence of the Company; or (f) any other circumstances which might otherwise constitute a defense available to, or a discharge of, the Company or a guarantor (except full and indefeasible payment of the Obligations). -2- The obligations of Subsidiary under this Agreement shall not be subject to reduction, termination or other impairment by reason of any setoff, recoupment, counterclaim or defense or for any other reason (except full and indefeasible payment of the Obligations). This Agreement is to be in addition to and is not to prejudice or be prejudiced by any other securities or guaranties (including any guaranty signed by Subsidiary) which the Noteholders may now or hereafter hold from or on account of the Company and is to be binding on Subsidiary as a continuing security notwithstanding any payments from time to time made to the Noteholders or any settlement of account or disability or incapacity affecting Subsidiary or any other thing whatsoever. This Agreement is a continuing guaranty and shall remain in full force and effect until payment in full of the Obligations and all other amounts payable under this Agreement and the termination of the Commitments.

Notwithstanding the provisions of SECTION 4.12, Subsidiary hereby expressly waives each and every right to which it may be entitled by virtue of the suretyship laws of the State of Texas, including, without limitation, any and all rights it may have pursuant to Rule 31 or Rule 32, Texas Rules of Civil Procedure, Section 17.001 of the Texas Civil Practice and Remedies Code and Chapter 34 of the Texas Business and Commerce Code. Subsidiary hereby waives marshalling of assets and liabilities, sale in inverse order of alienation, notice by the Noteholders of any indebtedness or liability to which it applies or may apply any amounts received by the Noteholders, and of the creation, advancement, increase, existence, extension, renewal, rearrangement and/or modification of the Obligations. SECTION 2.04. WAIVER OF SUBROGATION; ETC. Subsidiary will not exercise any rights of subrogation under this Agreement, by any payment made hereunder or otherwise, until such time as the Noteholders have received full payment of the Obligations and the Commitments have terminated. If, notwithstanding the preceding sentence, any amount shall be paid to Subsidiary on account of subrogation rights at any time when all the Obligations shall not have been paid in full, such amount shall be held in trust for the benefit of the Noteholders and shall forthwith be paid to the Noteholders to be credited and applied upon the Obligations in accordance with the terms of the Note Agreement.

SECTION 2.08. NO WAIVER; REMEDIES.

The remedies herein provided are cumulative and not exclusive of any remedies provided by law. SECTION 2.09. FURTHER ASSURANCES. Subsidiary hereby agrees to execute and deliver all such instruments and take all such action as the Noteholders may from time to time reasonably request in order to fully effectuate the purpose of this Agreement.
