Section 3. SUBORDINATION IN THE EVENT OF CERTAIN DEFAULTS. Subordinated Creditor and each Loan Party agree as follows: (a) If, from time to time, any default in the payment on account of any principal of or interest on, or any other amounts owing in respect of any Senior Debt (whether at maturity or at a date fixed for prepayment or by declaration, acceleration or otherwise) occurs or exists, then (i) the rights of Subordinate Creditor to receive any payments or other distributions with respect to the Subordinate Debt shall be suspended from and after the date of such default, and (ii) no payment or distribution of any character, whether in cash or cash equivalents, securities or other property (other than as permitted in Section 3(c) below) shall be made by any Loan Party, or received or accepted by Subordinate Creditor, on account of the Subordinate Debt until the Senior Debt is paid in full or all defaults are cured. (b) If, from time to time, any default, other than a payment default, under the Senior Loan Documents occurs or exists, then (i) the rights of Subordinate Creditor to receive any payments or other distributions with respect to the Subordinate Debt shall be suspended from and after the date that Subordinate Creditor receives a notice to suspend payments under the Subordinate Debt (a "STOP PAYMENT NOTICE"), and (ii) no payment or distribution of any character, whether in cash or cash equivalents, securities or other property (other than as permitted in Section 3(c) below) shall be made by any Loan Party, or received or accepted by Subordinate Creditor from any Loan Party, on account of the Subordinate Debt, or in respect of the redemption, retirement, purchase or other acquisition thereof, unless and until such default shall have been cured or waived or 179 days shall have elapsed since the date upon which Subordinate Creditor received such Stop Payment Notice, whichever is earlier, unless a payment default is then outstanding (including as a result of acceleration of the Senior Debt following a non-payment default in which event Section 3(a) shall govern); provided, however, that the Senior Creditors shall not be entitled to send a Stop Payment Notice for a period of 179 days after the expiration of a Stop Payment Notice unless an Enforcement Notice shall have been given. (c) Notwithstanding the foregoing, nothing herein shall prevent Subordinate Creditor from converting its Subordinated Debt to common stock equity of Texoil, Inc. as provided in the Subordinate Loan Documents prior to the commencement of a Proceeding and retaining the -4- same free of the provisions of this Agreement. The effect of any conversion or attempted conversion after the commencement of a Proceeding is governed by Section 4 hereof. Section 4. SUBORDINATION IN THE EVENT OF INSOLVENCY, ETC. In the event and during the continuance of any Proceeding, Subordinated Creditor and each Loan Party agree that all Senior Debt shall first be finally and irrevocably paid in full in cash or cash equivalents before any payment or distribution of any character, whether in cash or cash equivalents, securities or other property (including securities that are subordinate and junior in right of payment to the payment of Senior Debt to at least the extent provided for in this Agreement) shall be made, received or accepted for or on account of any Subordinate Debt. In the event of any Proceeding, any payment or distribution in any such Proceeding of any kind or character, whether in cash or cash equivalents, securities or other property which would otherwise (but for this Agreement) be payable or deliverable in respect of any Subordinate Debt shall be paid or delivered by the person making such distribution or payment, whether a trustee in bankruptcy, receiver, assignee for the benefit of creditors, liquidating trustee or agent, or otherwise, directly to Agent for the benefit of Senior Creditors, for application in payment of the Senior Debt in accordance with the priorities then existing among such holders, to the extent necessary to pay in full all Senior Debt then remaining unpaid, after giving effect to any concurrent payment or distribution to the holders of Senior Debt. Subordinate Creditor may appear and be heard on any matter relating to Subordinate Creditor's claim, but Subordinate Creditor agrees that it shall not (a) vote in favor of any plan of reorganization that would cause Subordinate Creditor to be paid ahead of any Senior Creditor in violation of the provisions of this Agreement, or (b) seek to assert rights contrary to the provisions of this Agreement. Section 5. STANDSTILL. Subordinate Creditor agrees not to accelerate the maturity of the Subordinate Debt or to exercise or enforce any rights or remedies under the Subordinate Loan Documents with respect to a default or otherwise to collect or seek to collect the Subordinate Debt (including by way of example and not of limitation, upon the occurrence of a Change in Control (as defined in the Subordinate Loan Documents) unless it gives the Agent an Enforcement Notice and until the latest of occur of: (a) 45 days following receipt by the Agent of the Enforcement Notice, (b) expiration of 135 days after receipt of a Stop Payment Notice delivered to Subordinate Creditor within 45 days after receipt by the Agent of an Enforcement Notice and (c) any payment defaults on the Senior Debt are cured. The failure to make a payment of principal of, interest on, or fees, costs or expenses relative to any of the Subordinate Debt by reason of any provision of this Agreement shall not be construed as preventing the occurrence of a default or event of default with respect to such Subordinate Debt. Nothing in this Section 5 affects the provisions and agreements of any Loan Party or Subordinate Creditor found in Sections 3 or 4 hereof. Section 6. PAYMENTS NOTWITHSTANDING. No payment or distribution of any character, whether in cash, cash equivalents, securities or other property (including securities which are subordinate and junior in right of payment to the payment of Senior Debt to at least the extent provided for in this Agreement) to which Subordinate Creditor would have been entitled except for the provisions of this Agreement and that shall have been made to or for the account of any Senior Creditor shall, as between each Loan Party and its creditors (other than Agent and Senior Creditors), -5- be deemed to be a payment or distribution by such Loan Party to or for the account of Senior Creditors, and from and after the payment in full in cash or cash equivalents of all Senior Debt, Subordinate Creditor shall be subrogated to all rights of Senior Creditors to receive any further payments or distribution applicable to the Senior Debt until the principal of and interest on the Subordinate Debt shall be paid in full, and no such payment or distribution made pursuant to such rights of subrogation to Subordinate Creditor that otherwise would be payable or distributable to or for the account of Agent or Senior Creditors or any or some of them shall, as between each Loan Party and its creditors (other than Subordinate Creditor), be deemed to be a payment or distribution by such Loan Party to Subordinate Creditor or on account of the Subordinate Debt. Section 7. NO PREJUDICE OR IMPAIRMENT. The provisions of this Agreement are solely for the purposes of defining the relative rights of Agent and Senior Creditors, on the one hand and Subordinate Creditor, on the other hand. Neither Agent nor any Senior Creditor shall be prejudiced in the right to enforce subordination of the Subordinate Debt by any act or failure to act by any Loan Party or anyone in custody of its assets or property. Nothing herein shall impair, as between each Loan Party and Subordinate Creditor, the obligation of such Loan Party, which is unconditional and absolute, to pay to Subordinate Creditor the principal of and interest on the Subordinate Debt as and when the same shall become due in accordance with their terms, nor shall anything herein prevent Subordinate Creditor from exercising all remedies otherwise permitted by applicable law upon default under the Subordinate Loan Documents, subject, however, to the provisions of this Agreement and the rights of Agent and each Senior Creditor to the extent provided herein. Nothing contained in this Section 7 (or elsewhere in this Agreement) shall limit the right of Agent or any Senior Creditor to recover from Subordinate Creditor any payments prohibited by this Agreement, including any payments or other distributions made during the existence of a payment default on the Senior Debt (regardless of whether Subordinate Creditor has any notice or knowledge thereof at the time of such payment or distribution). Section 8. TURNOVER OF PAYMENTS. If any payment, distribution or security (including securities which are subordinate and junior in right of payment to the payment of Senior Debt to at least the extent provided for in this Agreement), or the proceeds of any thereof, shall be collected or received by Subordinate Creditor in contravention of any of the terms of this Agreement and prior to the irrevocable payment in full in cash or cash equivalents of Senior Debt at the time outstanding, the holder thereof will forthwith deliver such payment, distribution, security or proceeds (with the endorsement, without recourse or warranty, of Subordinate Creditor where necessary) to Agent for the benefit of Senior Creditors and, until so delivered, the same shall be held in trust by such holder as the property of Senior Creditors. If Subordinate Creditor fails to make any endorsement required under this Agreement, Agent and each Senior Creditor, and their respective officers and employees on their behalf, are hereby irrevocably appointed as attorneys-in-fact (coupled with an interest) for the Subordinate Creditor to make such endorsement in Subordinate Creditor's name. Without limiting the foregoing, in the event any payment on the Senior Debt is recovered by or required to be paid over to a Loan Party or any receiver, trustee in bankruptcy, liquidating trustee, agent or other person in any Proceeding, any payments made by a Loan Party to Subordinate Creditor shall be held in trust for Agent and Senior Creditors and immediately remitted to Agent for the benefit of Senior Creditors upon demand. -6- Section 9. PRIORITIES REGARDING COLLATERAL. Any and every lien and security interest in the Collateral in favor of or held for the benefit of Agent or any Senior Creditor has and shall have priority over any lien or security interest that Subordinate Creditor now has or may hereafter acquire in the Collateral notwithstanding any statement or provision contained in the Subordinate Loan Documents or otherwise to the contrary and irrespective of the time or order of filing or recording of financing statements, deeds of trust, mortgages or other notices of security interests, liens or assignments granted pursuant thereto, and irrespective of anything contained in any filing or agreement to which any party hereto or its respective successors and assigns may now or hereafter be a party, and irrespective of the ordinary rules for determining priorities under the Uniform Commercial Code or under any other law governing the relative priorities of secured creditors. Subordinate Creditor has no Collateral, and shall not seek or take from any Loan Party Collateral for the Subordinate Debt. Section 10. COMPROMISE OF CLAIMS. Until the Senior Creditor has received indefeasible payment in full in cash or cash equivalents of all of the Senior Debt, the Subordinate Creditor agrees that the Senior Creditor may at any time and from time to time, without the Subordinate Creditor's consent, and without notice to the Subordinate Creditor, do any one or more of the following in the Senior Creditor's sole and absolute discretion: (a) renew, accelerate, extend the time for payment of, or increase the Senior Debt beyond the amount permitted in the definition thereof found in this Agreement and any or all of the obligations of any Loan Party, of any guarantors of any Loan Parties, or of any other party at any time directly or contingently liable for the payment of any of the Senior Debt; (b) grant any other indulgence to any Loan Parties, or any other person in respect of any or all of the Senior Debt or any other matter; (c) amend, alter, waive, or change in any respect whatsoever any term or provision relating to any or all of the Senior Debt, including the rate of interest thereon, or the Senior Loan Documents; (d) substitute or add, or take any action or omit to take any action which results in the release of any one or more endorsers or guarantors of all or any part of the Senior Debt; (e) apply any sums received from a Loan Party, any guarantor, endorser, or cosigner, or from the disposition of any Collateral or security, to any indebtedness whatsoever owing from such person or secured by such Collateral or security, in such manner and order as Agent determines in its sole discretion, and regardless of whether such indebtedness is part of the Senior Debt, is secured, or is due and payable; (f) permit a Loan Party to use proceeds of the Collateral for any purpose; (g) make loans or advances to a Loan Party secured in whole or in part by the Collateral or refrain from making any such loans or advances; (h) accept partial payments of, compromise or settle, refuse to enforce, or release all or any parties to, any or all of the Senior Debt; (i) settle, release (by operation of law or otherwise), compound, compromise, collect or liquidate any of the Senior Debt or the Collateral in any manner permitted by applicable law; (j) accept, release, waive, surrender, enforce, exchange, modify, impair or extend the time for the performance, discharge or payment of, any and all property of any kind securing any or all of the Senior Debt or any guaranty of any or all of the Senior Debt, or on which Agent or any Senior Creditor at any time may have a lien, or refuse to enforce its rights or make any compromise or settlement or agreement therefor in respect of any or all of such property, (k) fail to perfect any Collateral and (l) take or fail to take any action the consequence of which would be to release a surety or guarantor of the Senior Debt. Neither Agent nor any Senior Creditor is under nor shall any of them hereafter be under any obligation to marshal any assets in favor of the -7- Subordinate Creditor, or against or in payment of any or all of the Senior Debt, and may proceed against any of the Collateral in such order and manner as it elects. Notwithstanding the foregoing, the Borrowers and the Senior Creditors agree that they will not extend the final maturity of the Senior Debt without the prior written consent of the Subordinate Creditor. Section 11. BENEFIT OF AGREEMENT; AMENDMENTS OF CERTAIN DOCUMENTS; ETC. This Agreement shall constitute a continuing offer to all persons who, in reliance upon such provisions, become a Senior Creditor, and such provisions are made for the benefit of such Senior Creditor and each of them may enforce such provisions. Acceptance and notice of acceptance hereof by any Senior Creditor are expressly waived. The provisions of the Subordinate Loan Documents may not be altered, amended or modified in any respect that adversely affects Senior Creditor or violates the terms of the Senior Loan Documents as such documents are in effect as of the date of such amendment or modification without each Senior Creditor's written consent. Neither Agent or any Senior Creditor nor Subordinate Creditor shall have any obligation to preserve rights in the Collateral against any prior parties or to marshal any of the Collateral for the benefit of any person. No failure to exercise, and no delay in exercising on the part of any party hereto, any right, power or privilege under this Agreement shall operate as a waiver thereof; nor shall any single or partial exercise of any right, power or privilege under this Agreement preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies provided in this Agreement are cumulative and shall not be exclusive of any rights or remedies provided by law. Any agreements, documents or instruments which at any time evidence the Subordinate Debt or any part thereof shall state that payment thereunder is subject to the terms and provisions of this Agreement. If Subordinate Creditor should fail to file a proof of claim on account of the Subordinate Debt in any Proceeding within 30 days before the expiration of the time period within which creditors must file their proofs of claim, Subordinate Creditor agrees that Agent may file such claim in the Subordinate Creditor's place and stead, and as Subordinate Creditor's attorney-in-fact (coupled with an interest) for such purposes for the term of this Agreement. Section 12. REPRESENTATIONS AND WARRANTIES; ETC. Each of the parties hereto hereby represents and warrants that (a) it has full power, authority and legal right to make and perform this Agreement, and (b) this Agreement is its legal, valid and binding obligation, enforceable against it in accordance with its terms. Section 13. AMENDMENT. Neither this Agreement nor any of the terms hereof may be amended, waived, discharged or terminated unless such amendment, waiver, discharge or termination is in writing signed by Agent and Subordinate Creditor. Section 14. SUCCESSORS AND ASSIGNS. This Agreement, and the terms, covenants and conditions hereof, shall be binding upon and inure to the benefit of the parties hereto, and their respective successors and assigns. Subordinate Creditor and Agent (on behalf of the Senior Creditors) further agree between themselves and solely for their own collective benefit, that if a Borrower is in the process of refinancing all or a portion of the Senior Debt with a new lender or lenders, and if the party who wishes to be refinanced makes a request of the other parties hereto, -8- Subordinate Creditor shall agree to enter into a new, substitute agreement with the new lender; PROVIDED, HOWEVER, that if any such new, substitute agreement shall be in a form (other than with appropriate date, name and address changes), and contain such terms and conditions other than as provided herein, the form, terms and conditions of such new, substitute agreement shall be acceptable to the party whose financial accommodations to Borrowers are not being refinanced; and PROVIDED, FURTHER, HOWEVER, that in no circumstances shall the party hereto whose financial accommodations to a Borrower are not being refinanced be obligated to enter into such an agreement if the substitute agreement deprives it of any material right, privilege or benefit accorded to it hereunder.

Section 18. ADDITIONAL DOCUMENTATION. Each party hereto hereby agrees to execute such additional documents and instruments and take such further actions as may be reasonably required to carry out the purposes and intent of this Agreement. Section 19. CONSTRUCTION; INTERPRETATION. Each party hereto has cooperated in the drafting and preparation of this Agreement, and as a result this Agreement shall not be construed against any party. Whenever the context requires, all words used in the singular will be construed to have been used in the plural, and vice versa. The captions of the sections of this Agreement are for convenience only and do not define or limit any terms or provisions. The word "include(s)" means "include(s) without limitation" and the word "including" means "including but not limited to." Time is of the essence in the performance of this Agreement. If any provision of this Agreement shall for any reason be determined by a court of competent jurisdiction, and sustained on appeal, if any, to be unenforceable in any respect, such enforceability shall not affect any other provisions hereof, and this Agreement shall be construed if such unenforceable provision had not been contained herein; provided, if any provision of this Agreement shall be unenforceable by reason of a final judgment of a court of competent jurisdiction based upon such court's ruling, and sustained on appeal, if any, that such provision is unenforceable because of the unenforceable degree or magnitude of the obligation imposed thereby, such unenforceable obligation shall be reduced in magnitude or degree by the minimum amount necessary in order to provide the maximum degree or magnitude of rights which are enforceable, and this Agreement shall be automatically and retroactively amended accordingly to contain such maximum degree or magnitude of such obligation which is enforceable, rather than the more burdensome but enforceable original obligation. As used herein, "unenforceable" is used in the broadest and most comprehensive sense and includes the concepts of void and voidable. Section 20. COUNTERPARTS. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Section 21. WAIVER OF RIGHT TO TRIAL BY JURY. EACH PARTY TO THIS AGREEMENT HEREBY EXPRESSLY WAIVES ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (A) ARISING UNDER THIS AGREEMENT OR ANY OTHER INSTRUMENT, DOCUMENT OR AGREEMENT EXECUTED OR DELIVERED IN CONNECTION HEREWITH, OR (B) IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO OR ANY OF THEM WITH RESPECT TO THIS AGREEMENT OR ANY OTHER INSTRUMENT, DOCUMENT OR AGREEMENT EXECUTED OR DELIVERED IN CONNECTION HEREWITH, OR THE TRANSACTIONS RELATED HERETO OR THERETO, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT OR TORT OR OTHERWISE; AND EACH PARTY HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM, -11- DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY, AND THAT ANY PARTY TO THIS AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY. Section 22. SURETY ISSUES, ETC. The Subordinate Creditor hereby waives and agrees not to assert against Agent or any Senior Creditor any rights which a guarantor or surety could exercise (including any rights under Chapter 34 of the Texas Business and Commerce Code), but nothing in this Agreement shall make or constitute the Subordinate Creditor a guarantor or surety, and the Subordinate Creditor hereby waives the right, if any, to require that any Senior Creditor marshal or otherwise require any Senior Creditor to proceed to dispose of or foreclose upon collateral in any manner or order. Advances are senior and superior in right of payment to the Subordinate Debt even if made after a Senior Creditor has notice of default in the Subordinate Debt and/or irrespective of whether any such advance is objected to by Subordinate Creditor. No Senior Creditor shall be responsible to ascertain compliance with the Subordinate Loan Documents or be liable if Senior Debt is incurred in violation thereof. Section 23. REINSTATEMENT IN CERTAIN EVENTS. The provisions of this Agreement shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Senior Claims is rescinded or must otherwise be returned by any Senior Creditor or any or some of them upon the insolvency, bankruptcy or reorganization of a Borrower or otherwise, all as though such payment had not been made. Section 24. REPRESENTATIONS AND WARRANTIES OF SUBORDINATE CREDITORS.

Section 25. REPRESENTATION AND COVENANT OF AGENT. The Agent represents that the Commitment Termination Date under the Senior Loan Documents is August 4, 2000. Senior Creditors will not amend Section 6.8 of Amended and Restated Credit Agreement constituting one of the Senior Loan Documents without the prior written consent of the Subordinate Creditor.
